SUMMARY:
PrEP is one of the most effective ways for you to lower your chance of getting HIV infection. It can be used in combination with other methods including condoms, making sure any sexual partners living with HIV are taking their meds the right way and staying undetectable, and not sharing needles or injection equipment if you inject drugs. PrEP can work for everyone regardless of biological sex, gender identity, or sexual orientation and can also reduce the chance of HIV transmitted through injection drug use. PrEP puts YOU in control of your sexual health.
What is PrEP?
- PrEP stands for Pre-Exposure Prophylaxis
- “Pre-exposure” means having medicine in your system even before you have sex
- “Prophylaxis” means the medicine prevents you from getting HIV even if your partner has it
- There are different PrEP options to choose from (read more about these medications by tapping the ‘More About PrEP Meds’ entry’ at the top of this entry)
TDF/FTC (pills)
- TDF/FTC is one pill that contains two medicines and is also known as
- Truvada
- Tenofovir disoproxil fumarate/emtricitabine
TAF/FTC (pills)
- TAF/FTC, similar to TDC/FTC, is one pill that contains two medicines and is also known as
- Descovy
- Tenofovir alafenamide/emtricitabine
Cabotegravir (injection)
- Cabotegravir injection is also known as
- Apretude
- CAB-LA
PrEP Works
- Many studies done across the globe have proven that when PrEP is taken correctly and consistently it is HIGHLY effective in preventing HIV infection
- When PrEP doesn’t work, it is usually because people miss too many doses of the medicine or don’t take it at all
PrEP is Safe
- Most people who take PrEP don’t have side effects
- When side effects do happen, they are usually mild and often go away after a few weeks of taking PrEP
Other Considerations:
- By law, almost all health insurances in the US must cover the costs of PrEP including
- Medicine
- Doctor visits
- Blood tests
- HIV testing
- STD testing
- PrEP can adapt to what’s happening in your life since your risk for HIV can change
- It’s a good idea to talk to your health care team about stopping PrEP before making that decision
- If things change again, you can restart
- PrEP does not protect against other STDs like gonorrhea, chlamydia, or syphilis
- Condoms are very good at preventing these infections when used correctly
NOTE: You have to be on most PrEP medicines for at least one week before you can be sure that they’re working, and for at least three weeks if you are a cisgender woman or transgender man who has vaginal sex | You will also need an HIV test before restarting

SUMMARY:
There are three PrEP Meds Available in the US. Two types you can take in a pill form by mouth and one type is a needle injection. All three can reduce your risk of HIV if taken according to instructions. Below, we review these medications that can help keep you safe and healthy.
TDF/FTC
- TDF/FTC is one pill that contains two medicines and is also known as
- Truvada
- Tenofovir disoproxil fumarate/emtricitabine
- Takes about a week to build up to protective levels in your system, except in the vagina where it can take three weeks
- TDF has been used as a medicine for HIV since 2001 and FTC since 2004
- These meds have been around for a long time
- The combination of these two medications, TDF/FTC, has been used in the US for PrEP since 2012
- Generic TDF/FTC has been used in the US since 2020
- This means that the pill can look different based on which company makes it
- Generic TDF/FTC is just as effective as “brand-name” Truvada
- When and how to take TDF/FTC
- It is a tablet that you take once a day, every day, if there’s a chance you could get HIV from your partner(s)
- You can take it with or without food
Side Effects
- TDC/FTC has very few side effects | In fact, most people will have no significant side effects
- Stomach
- Sometimes TDC/FTC can upset your stomach
- Unless it is making you very sick, this side effect usually passes after two to four weeks if you stay on the medicine
- Kidney (also known as renal)
- Side effects are very rare
- Your healthcare professional will want to do a blood test every six to twelve months to check your kidneys
- If there is a kidney problem on TDF/FTC, it usually gets better after stopping the medicine
- Thinning of bones
- Side effects are very rare but can also occur
- TDC/FTC does not usually cause pain
- Taking calcium and vitamin D pills may help to avoid bone side effects
TAF/FTC
- TAF/FTC, similar to TDC/FTC, is one pill that contains two medicines and is also known as
- Descovy
- Tenofovir alafenamide/emtricitabine
- Takes about a week to build up to protective levels in your system
- TAF has been used as a medicine for HIV since 2015 and FTC since 2004
- These meds have been around for a long time
- TAF/FTC has been used in the US for PrEP since 2019
- TAF/FTC is ONLY approved for use by
- Cisgender men
- Transgender women
- It is not known whether it works in cisgender women since its ability to prevent HIV in the vagina is uncertain
- When and how to take TAF/FTC
- Taken the same way as TDF/FTC
- One pill once per day, if there’s a chance you could get HIV from your partner(s)
- You can take it with or without food
Side Effects
- TAF/FTC has very few side effects | In fact, most people will have no significant side effects
- Stomach
- Sometimes it can upset your stomach
- Unless it is making you very sick, this side effect usually passes after two to four weeks if you stay on the medicine
- Kidney and bone effects
- TAF/FTC probably has fewer kidney and bone side effects than TDF/FTC
- Your healthcare professional will want to do a blood test every six to twelve months to check your kidneys
- Taking calcium and vitamin D pills may help to avoid bone side effects
Note: You don’t have to take PrEP pills at exactly the same time every day | It’s more important that if you’re taking oral PrEP you make sure to get it in your system every day
Cabotegravir
- Cabotegravir injection is also known as
- Apretude
- CAB-LA
- Cabotegravir has been used in the US as a medicine for HIV since January 2021
- In December 2021, cabotegravir was approved for PrEP as a long-acting injection every two months
- The protection that you get from cabotegravir every two months is at least as good as taking TDF/FTC or TAF/FTC every day
- One of the best things about cabotegravir is that you get the injection every two months, and you don’t have to worry about taking pills
- If you decide to take cabotegravir PrEP
- You will have to see your healthcare professional every two months for the injection
- If you’re worried you might miss an injection, you should speak to your healthcare professional
- To start cabotegravir PrEP
- You either have to get an injection every month for the first two months or
- You can take cabotegravir pills every day for a month before switching to an injection every two months
- It is not known how long you have to wait after your first injection until you are protected
- It would make sense to wait seven days as is done for the other types of PrEP
- If you are switching from TDF/FTC or TAF/FTC to cabotegravir, you do not have to wait
- The cabotegravir injections must be given in the buttocks
Side Effects
- In general, cabotegravir is considered safe
- The only common side effect is pain or swelling where you get the injection
- This usually happens less and less as you stay on the drug
- You can take over the counter pain relievers (like Tylenol) and/or use heating pads to relieve the pain
- It is rare for people to stop cabotegravir because of the pain
Other Things You Should Know
- What if you don’t want to take a pill every day?
- Depending on how frequently someone is at risk for HIV, taking a pill every day may not be the best option
- People with less frequent risk who have decided to take TDF/FTC may talk to their provider about the possibility of “on-demand” or “2-1-1” PrEP instead of taking a pill every day
- This is an option that has only been recommended for men who have sex with men, and you should discuss it with your provider if you don’t want to take a pill every day
- Switching from one PrEP drug to another
- If you want to switch from one PrEP medicine to another, it can probably be done safely, but it is something that you should discuss with your healthcare professional to make sure it is done safely and correctly
- Stopping and restarting PrEP
- You might consider stopping PrEP if you are no longer at risk for HIV
- Remember that once PrEP is stopped, you will no longer have protective levels of the medication in your system
- If you stop PrEP, you will need an HIV test first to make sure it is negative before you can restart

SUMMARY:
What is PrEP?
- PrEP stands for Pre-Exposure Prophylaxis
- “Pre-exposure” means having medicine in your system even before you have sex
- “Prophylaxis” means the medicine prevents you from getting HIV even if your partner has it
What’s Changed?
- Until 2012
- The only ways to avoid getting HIV from sex were
- To not have sex
- Never have sex with someone with HIV
- Use condoms properly every single time
- And still … way too many people still got HIV from sex
- The only ways to avoid getting HIV from sex were
- Today, there are more ways to reduce your risk of HIV
- Newer medications for people with HIV that really work
- If your partner has HIV, make sure your partner takes HIV meds and has an undetectable HIV viral load | “Undetectable” means that the HIV virus cannot be found in the person’s blood
- Someone who STAYS undetectable by taking meds the right way can’t give anyone else the virus through sex
- Take PrEP to protect yourself if you don’t have HIV
- Newer medications for people with HIV that really work
More on PrEP
- When PrEP medicine is taken correctly it provides safe and excellent protection against HIV
- IF YOU DON’T TAKE IT, IT CAN’T WORK
- In most states, you cannot get PrEP without a physician prescription | In certain states, pharmacists may provide PrEP to people without a doctor’s prescription
WHAT TO EXPECT WHEN YOU GO FOR A VISIT:
The Health Care Team Will Probably Ask You About
- Your sexual history, your sexual preferences, and your sexual risks
- Don’t be embarrassed
- These questions are important to help you and your health care team create an HIV prevention plan that works for you to keep you healthy
- Ask you about your other medical history
- Do a physical examination
- Test your blood for
- HIV test: You can’t take PrEP if you already have HIV
- Kidney test to see how your kidneys are working: Needed before starting some PrEP meds
- Pregnancy test (if you are able to get pregnant). Most PrEP treatments are considered to be safe during pregnancy, but pregnant women should review any medicines that they take with their health care teams.
- Test you for other infections that can be spread through sex
- These infections are also known as Sexually Transmitted Diseases or STDs | They are also sometimes called STIs (Sexually Transmitted Infections)
- The STDs that you will most likely be tested for are syphilis, gonorrhea, and chlamydia
- The tests usually involve swabs from the genital, anal, and oral areas | The syphilis test is a blood test
- Often, patients can collect their own swabs (like Q-tips) from these areas
- Hepatitis B: Tests for liver infection | Some of the PrEP medicines can cause problems in people who have hepatitis B infection (a type of liver infection caused by a virus)
The Healthcare Team Will Probably Discuss the Following with You
- What is PrEP?
- What are your different PrEP choices?
- How to take PrEP correctly
- What are the side effects to look for?
- Serious side effects are very rare!
- Safer sex: What are ways to avoid other STDs
Next Steps Before You Leave
- You will likely get a prescription
- To start PrEP right away or
- Start taking it after your blood tests come back okay
- Until December 2021, PrEP was only available as pills
- There is now another choice – an injection that you take every two months
- Your health care team may discuss with you the choice of pills or injections
- You will get an appointment for a follow-up visit in 1 to 3 months
- As long as you are on PrEP, your health care team will probably need to see you 2 to 4 times a year for a check-up, an HIV test, and STD testing

American Gastroenterology Association (AGA) Clinical Practice Obesity Guideline Including Pharmacological Interventions
Summary:
Obesity, defined by the CDC as a weight that is higher than what is considered healthy for a given height, has been increasing in prevalence over several decades. Roughly two thirds of adults are considered obese or overweight, with a recent estimate putting the prevalence of adults with obesity at nearly 42% of the population. It is customary to use BMI calculations as both a screening tool and to further characterize the degree of obesity, but it is important to note that BMI does not diagnose a patient’s health or even degree of body fat. Healthcare providers should combine appropriate clinical assessments, considering body weight, central fat distribution, functional status, and presence of obesity related complications, to create a more accurate picture of a patient’s health. In recent years we have gained a better understanding of what contributes to obesity and what helps a patient maintain a healthy weight. The AGA has accordingly updated their guidelines on pharmacological interventions for adults with obesity to better help clinicians care for their obese patients.
Diagnosis
All adults should be screened for obesity by obtaining a height and weight and calculating BMI during a routine physical exam (see ‘Learn More – Primary Sources’ for CDC BMI Calculator)
BMI can be calculated via calculator or by dividing weight (kg) over height (m)2
- Underweight: <18.5 kg/m 2
- Normal weight: ≥18.5 to 24.9 kg/m 2
- Overweight: ≥25.0 to 29.9 kg/m 2
- Obesity: ≥30 kg/m 2
Obesity can be further characterized by class
- Class I: 30.0 to 34.9 kg/m 2
- Class II: 35.0 to 39.9 kg/m 2
- Class III: ≥40 kg/m 2
A BMI over 25 kg/m 2 should prompt further evaluation including
- Measurement of waist circumference: > 40 inches in men and > 35 inches in women is associated with increased risk for obesity related complications
- Screening for obesity related complications (see below)
- Consideration of causes of weight gain not related to diet and activity level (e.g., hypothyroidism, drug side effect, depression, Cushing’s syndrome)
- Blood pressure measurement
- Fasting glucose and lipid levels
Note: A BMI > 23 kg/m2 may indicate the need for further evaluation in patients of South Asian, Southeast Asian, and East Asian descent as obesity related complications develop at lower BMIs in these populations
Obesity related complications
- Type 2 Diabetes Mellitus (T2DM), Prediabetes
- Cardiovascular disease
- Hypertension
- Hyperlipidemia
- Obstructive sleep apnea
- Obesity hypoventilation syndrome
- Nonalcoholic fatty liver disease
- Osteoarthritis
- Stroke
- Certain malignancies (e.g., colorectal cancer, endometrial cancer)
- Depression
- PCOS, Infertility
- GERD
- Urinary incontinence
- VTE
- Gallstones
Lifestyle Interventions
The cornerstones of weight loss management are individualized dietary changes and increased physical activity. Recent guidelines, including the USPSTF recommendations, recommend the use of behavioral therapy and a multidisciplinary approach involving weight loss counselors, psychologists, physical therapists and dieticians to assist the patient in establishing and reaching their weight loss goals.
Weight loss goals should be modest
- A weight reduction of 5% to 10% of initial body weight is sufficient to yield significant health benefits including decreased risk of diabetes and cardiovascular disease
- A 5% weight loss within 3 months is used by the US Food and Drug Administration (FDA) to assess the efficacy of medications to treat obesity
Increased calorie expenditure
- Adults should perform at least 150 minutes of moderate-intensity or 75 minutes of vigorous-intensity aerobic activity per week (or an equivalent combination of these)
Decreased calorie intake
- Reducing daily calorie intake to 1200 to 1500 for women and 1500 to 1800 for men
- Estimating an individual’s daily energy requirements and aiming for an energy deficit of 500 kcal/d or 750 kcal/d
Pharmacological Therapies
In adults with obesity or overweight with weight-related complications, who have had an inadequate response to lifestyle interventions, the AGA recommends adding pharmacological agents to lifestyle interventions over continuing lifestyle interventions alone.
Clinical Considerations
Anti-obesity medications (AOMs) are not recommended for:
- Pregnant women
- Patients with bulimia nervosa
Use caution when starting AOMs for patients with:
- Diabetes treated with insulin or insulin secretagogues (e.g., sulfonylureas) as AOMs may decrease blood sugar levels
- Hypertension or those on blood pressure lowering agents, as AOMs may lower blood pressure as weight is lost
- Binge eating disorder
Cost of AOMs may limit their access and data on cost-effectiveness is limited
Recommended Anti-Obesity Medications
Semaglutide (Wegovy)
- Largest magnitude of net benefit, so can be considered first line prior to other drugs
- Dosing is started at 0.25 mg/week escalated gradually to goal of 2.4 mg/week

Noninvasive Treatments for Acute, Subacute, and Chronic Low Back Pain: A Clinical Practice Guideline from the American College of Physicians
SUMMARY:
Low back pain is a common complaint in outpatient settings, with an estimated 25% of adults reporting an episode of low back pain lasting for at least one day in the past three months. It is associated with high healthcare costs and is a leading cause of activity limitation and missed worked days globally. The diagnosis of low back pain can be clinically frustrating, with the majority of cases unattributable to a specific cause. The American College of Physicians last released guidelines to aid in diagnosis and treatment of low back pain in 2007, and updated their treatment guidelines in 2017, stressing non-pharmacological therapies for most types of back pain.
Clinical Presentation
Diagnosis
- Obtain detailed history and physical
- Pay attention for signs and symptoms of radiculopathy or spinal stenosis
- Assess for other symptoms or illnesses that may contribute to back pain (e.g., history of autoimmune disease, falls, and injuries)
- Imaging is typically not recommended for non-specific back pain, and should only be done when it will change management
Etiologies
- Mechanical: Lumbar Strain | Fracture | Osteoporosis | Herniated Disc | Degenerative disc disease
- Non-Mechanical: Malignancy | Osteomyelitis | Abscess | Inflammatory arthritis
- Visceral: Prostatitis | Endometriosis | Pancreatitis | Nephrolithiasis | Aortic aneurysm
- The vast majority of back pain will be non-specific with no obvious etiology
Definitions
- Acute: Pain lasting less than 4 weeks
- Subacute: Pain lasting 4 to 12 weeks
- Chronic: Pain lasting over 12 weeks
Treatment for Acute/Sub-Acute Low Back Pain
Given that most patients with acute or subacute low back pain improve over time regardless of treatment, clinicians and patients should select nonpharmacologic treatment with superficial heat (moderate-quality evidence), massage, acupuncture, or spinal manipulation (low-quality evidence). If pharmacologic treatment is desired, clinicians and patients should select nonsteroidal anti-inflammatory drugs or skeletal muscle relaxants.
Pharmacologic therapy
- No benefit: Tylenol | Systemic steroids
- Small benefit
- NSAIDs: Improved pain and function | Should be used at lowest effective dose for short periods of time to reduce associated risks (e.g., renal, GI risks)
- Skeletal muscle relaxants (SMR): Provided short term pain relief with studies showing no difference in outcomes between different SMRs
- Insufficient evidence to determine benefit: Antidepressants | Opioids | Benzodiazepines | Antiepileptics
Non-Pharmacologic
- No benefit: Exercise | Lumbar supports
Benefit
- Improved pain and function: Massage | Heat wrap | Low-level laser therapy (in conjunction with NSAIDs)
- Acupuncture improved pain only
- Spinal manipulation improved function only
Insufficient evidence
- Transcutaneous electrical nerve stimulation (TENS) | Electrical muscle stimulation | Inferential therapy | Short-wave diathermy | Traction | Superficial cold (ice) | Motor control exercise (MCE) | Pilates | Tai chi | Yoga | Psychological therapies | Multidisciplinary rehabilitation | Ultrasound | Taping
Note: Clinicians should reassure patients that the vast majority of acute/subacute low back pain improves with time regardless of therapies used
Treatment for Chronic Low Back Pain
For patients with chronic low back pain, clinicians and patients should initially select nonpharmacologic treatment with exercise, multidisciplinary rehabilitation, acupuncture, mindfulness-based stress reduction, tai chi, yoga, motor control exercise, progressive relaxation, electromyography biofeedback, low-level laser therapy, operant therapy, cognitive behavioral therapy, or spinal manipulation.
Non-Pharmacologic Therapy
Should be used first line due to minimal associated risks compared to pharmacologic therapies
No benefit: Foot reflexology | Ultrasound | Transcutaneous electrical nerve stimulation (TENS) | Taping
Benefit
- Improved pain and function: Exercise | Motor control exercise (MCE) | Tai chi | Yoga | Psychologic therapies (e.g., progressive relaxation therapy) | Multidisciplinary rehabilitation | Acupuncture | Massage | Low-level laser therapy
- Improved pain only: Electromyography biofeedback | Operant therapy | Cognitive behavioral therapy | Spinal manipulation
Insufficient evidence
- Lumbar support | Electrical muscle stimulation | Interferential therapy | Short-wave diathermy | Traction | Superficial heat or cold
In patients with chronic low back pain who have had an inadequate response to nonpharmacologic therapy, clinicians and patients should consider pharmacologic treatment with nonsteroidal anti-inflammatory drugs as first-line therapy, or tramadol or duloxetine as second-line therapy.
Clinicians should only consider opioids as an option in patients who have failed the aforementioned treatments and only if the potential benefits out-weigh the risks for individual patients and after a discussion of known risks and realistic benefits with patients.
Pharmacologic Therapy
No benefit:
- TCAs | SSRIs
Benefit:
- NSAIDs: Improved pain with possible small improvement in function. No difference in outcomes between NSAID types. Should be given at lowest effective dose for short periods of time to reduce harm
- Opioids: Improved short-term pain and function. No clear difference between opioid types and formulations (e.g., long vs short acting). Tramadol also effective
- Benzodiazepines: Specifically, tetrazepam improved pain
- SNRIs: Duloxetine improved pain and function
Insufficient evidence: SMRs | Tylenol | Systemic steroids | Antiepileptics
Key Points:
- Patient should be encouraged to remain active as tolerated despite low back pain
- Improvements in pain and function with different therapies (pharmacologic and non-pharmacologic) were small and many studies reviewed had low-quality evidence
- Few differences exist between the different pharmacologic and non-pharmacologic therapies outlined above
- Providers should use shared decision-making with the patient to choose which therapy would be most likely to help, based on individual patient traits and discussion of risks and benefits

AAD Guidelines for Management of Acne Vulgaris
Summary:
Acne vulgaris (AV) is a multifactorial chronic inflammatory skin disease that affects an estimated 50 million people in the United States, including approximately 85% of teenagers. While AV is not life threatening in and of itself, it is associated with significant physical and psychological morbidity and healthcare costs. The American Academy of Dermatology (AAD) has released guidelines for managing acne in adolescents and adults.
Quick Navigation
Classification and Grading:
- Currently no universal classification or grading system in recommended
- Despite this, acne is typically divided into mild, moderate and severe categories to help guide treatment and monitor for improvement with therapies
Mild Acne
- Typically limited to scattered comedones without scarring or nodules
- First line treatment includes: Benzoyl peroxide (BP) | Topical retinoid | Topical combination (BP +/- Retinoid +/- antibiotic)

Moderate Acne
- Visually obvious nodules, papules and comedones

Syphilis: CDC Diagnosis and Treatment Guidelines
WHAT IS IT?
Syphilis is a sexually transmitted infection caused by Treponema pallidum. Symptoms, diagnostic tests and treatment vary depending on stage of the disease. The syphilis rate has continued to increase in the US over the past decade. Without treatment, syphilis can damage the brain, nerves, eyes, and cardiovascular system.
Screening for Syphilis
Who to Screen
- The USPSTF task force recommends screening for the following populations (Grade A recommendation: “Offer or provide this service”)
- Asymptomatic, nonpregnant adolescents and adults who are at increased risk for syphilis infection
- All pregnant women early in pregnancy
- Factors associated with increased risk for syphilis include
- Higher prevalence of infection in particular communities
- Sociodemographic and behavioral factors (e.g., multiple sex partners, prevalence of syphilis is higher in males, men who have sex with men, drug use, persons living with HIV, young adults, and persons with a history of incarceration, sex work, or military service)
How to Screen
- Traditional screening: Initial “nontreponemal” antibody test (i.e., Venereal Disease Research Laboratory [VDRL] test or rapid plasma reagin [RPR] test) to detect biomarkers released from damage caused by syphilis infection, followed by a confirmatory “treponemal” antibody detection test (i.e., fluorescent treponemal antibody absorption [FTA-ABS] or T pallidum particle agglutination test [TP-PA])
- Reverse sequence screening algorithm: Automated treponemal test (such as an enzyme-linked [EIA], chemiluminescence [CIA], or multiplex flow immunoassay [immunoblot]) performed first, followed by a nontreponemal test
- If the test results of the reverse sequence algorithm are discordant, a second treponemal test (preferably using a different treponemal antibody) is performed
Primary Syphilis
Early disease, characterized by an ulcer or chancre at the infection site approximately 3 weeks after infection
- Diagnosis
- Darkfield examination and molecular tests of fluid/tissue for T. pallidum are definitive methods or
- Presumptive diagnosis requires both a (1) nontreponemal test (VDRL or RPR) and (2) a treponemal test (FTA-ABS, EIA, CIAs and immunoblots, rapid treponemal tests or TP-PA)
- Treatment
- Benzathine penicillin G 2.4 million units IM in a single dose
Secondary Syphilis
Symptoms can be diffuse and variable
- Symptoms
- Skin rash (classically with involvement of palms and soles) | Mucocutaneous lesions | Lymphadenopathyn | Fever | Alopecia | Ocular symptoms | Headache | Hepatitis
- Typically develops several weeks to months after primary infection
- Diagnosis
- Same as for primary syphilis
- Treatment
- Same as for primary syphilis
Latent Syphilis
No symptoms and no current evidence of primary, secondary, or tertiary disease
- Diagnosis of early latent syphilis
- Documented seroconversion or sustained ( >2 weeks) fourfold or greater increase in nontreponemal test or unequivocal symptoms of primary/secondary syphilis or a sex partner with documented primary/secondary syphilis all within the past year
- Treatment
- Early latent (acquired within 1 yr): Benzathine penicillin G 2.4 million units IM single dose
- Late latent (acquired > 1 yr): Benzathine penicillin G 7.2 million units total given IM in 3 weekly doses of 2.4 million units each
Tertiary Syphilis
Gummas, cardiovascular syphilis (CNS involvement (for neurosyphilis treatment, see below)
- Diagnosis
- Appearance of soft skin lesions and ulcers
- CXR shows linear calcifications of aorta
- Perform LP to rule out neurosyphilis
- Treatment
- Benzathine penicillin G 7.2 million units administered as 3 weekly doses of 2.4 million units
Neurosyphilis
Note: Can occur at any stage | Includes cranial nerve dysfunction, meningitis, stroke, altered mental status, auditory/ophthalmic abnormalities | Tabes dorsalis and paresis are late manifestations and can occur 10 to 30 years after infection
- Diagnosis
- Lumbar puncture: Test CSF for white blood cell count, protein and VDRL
- Treatment
- Aqueous crystalline penicillin G, 3 to 4 million units IV every 4 hours for 10 to 14 days or penicillin G procaine, 2.4 million units IM daily plus probenicid 500 mg orally 4 times daily, for 10 to 14 days
Note: The durations of the recommended and alternative regimens for neurosyphilis are shorter than the duration of the regimen used for latent syphilis | Therefore, benzathine penicillin, 2.4 million units IM once per week for 1 to 3 weeks, can be considered after completion of these neurosyphilis treatment regimens to provide a comparable total duration of therapy
KEY CLINICAL POINTS:
- Penicillin Allergy
- Patients with penicillin allergy should be desensitized and treated with penicillin whenever possible
- Doxycycline 100 mg BID x 14 days or tetracycline 500 mg 4 times daily for 14 days can be used for nonpregnant penicillin-allergic patients with primary or secondary syphilis
- Counsel patients regarding Jarisch-Herxheimer reaction
- Acute febrile reaction frequently accompanied by headache, myalgia, and fever
- Occurs within initial 24 hours after initiation of any syphilis therapy
- Reaction to treatment and not an allergic reaction to penicillin
- Occurs most frequently among persons who have early syphilis (likely due to heavier bacterial loads at this stage)
- Manage with antipyretics
- Nontreponemal titers decline after treatment and eventually become negative
- Treponemal tests remain positive for life
- Follow-up at
- 6, 12, 18 and 24 months after therapy and should include serology
- If symptoms persist or recur, or there is a >4 fold increase in nontreponemal test titer persisting more than 2 weeks
- consider reinfection or treatment failure
- retreat and check HIV status
- Sexual transmission occurs only when mucocutaneous lesions are present and is uncommon after the first year
- Persons exposed sexually to those with primary, secondary or early latent syphilis should be evaluated clinically and serologically

Depressive Disorders: Diagnosis and Treatment
SUMMARY:
Depressive disorders are characterized by the presence of a sad, empty, or irritable mood and are accompanied by somatic and cognitive changes that significantly impair a person’s ability to function. Depression due to Major Depressive Disorder is a leading cause of disability worldwide, and the leading risk factor for suicide. In the primary care setting up to 18% of patients have depression and about 9% of the US population meet criteria for depression. Many of these patients are not seen by psychiatrists or psychologists and depend on management and screening by their primary care providers.
SYMPTOMS:
- Depressed mood most of the day, nearly every day (can be self-reported or based on observation of others)
- Markedly diminished interest or pleasure in almost all activities most of the day, nearly every day
- Change in weight or appetite, either increased or decreased
- Change in sleep patterns, either increased or decreased
- Psychomotor agitation or retardation
- Fatigue or loss of energy
- Feelings of worthlessness or excessive guilt
- Diminished ability to think, concentrate, or indecisiveness
- Recurrent thoughts of death, recurrent suicidal ideation with or without a specific plan, or a suicide attempt
DIAGNOSIS:

- Symptoms occur within 3 months of the onset of an identifiable stressor
- Symptoms must be severe enough to cause distress outside of what would be expected, or to impair daily functioning
- Cannot meet criteria for other psychiatric disorder (e.g., MDD)
Substance/Medication-Induced Depressive Disorder
- Depressive symptoms associated with the ingestion, inhalation or injection of a substance
- Persists beyond the expected length of physiological effects, intoxication or withdrawal period.
Depressive Disorder Due to Another Medical Condition
- Prominent and persistent period of depressed mood or diminished interest in activities that predominates the clinical picture
- Thought to be related to the direct physiological effects of another medical condition
- Commonly associated medical conditions including hypothyroidism, CVA, Parkinson’s disease and Huntington’s disease
Other Specified Depressive Disorders
- Recurrent brief depression
- Depressed mood and 4 other above symptoms for 2 to 13 days every month for the past 12 months

Screening
The USPSTF recommends screening for depression in individuals > 12 years of age when there are systems in place to accurately diagnose and effectively treat, and to provide appropriate follow-up. Individuals with depressive disorders should be evaluated for suicide risk and safety planning should be done when appropriate.
- Common Screening Tools
- Patient Health Questionnaire (PHQ-9 and PHQ-2)Patient Health Questionnaire (PHQ-9 and PHQ-2)
- Geriatric Depression Scale
- Edinburgh Postnatal Depression Scale (EPDS)
Testing
- Diagnosis should be made on history according to the DSM-5 criteria listed in the above section | Other diagnosis should be considered based on history and physical exam
- Lab work can be considered if certain medical conditions are suspected to be contributing (e.g., TSH | RPR | B12 | CBC)
- Patients should be carefully screened for current or past symptoms of manic episodes as this would change diagnosis and medication treatment
- Symptoms of psychotic features would affect medication choices
- Evaluate for medications or substances that may be affecting mood (e.g. Alcohol | Opiates | Beta blockers)
KEY POINTS
- Depression is a common and debilitating illness that affects a significant number of patients, most of whom seek help from their primary care providers
- All adults should be screened for depression via a screening test such as the PHQ-2
- Treatment depends on severity of symptoms and includes pharmacotherapy, psychotherapy, or a combination of both

Update from the CDC: Practice Guidelines for Prescribing Opioids
SUMMARY:
Pain is one of the most common reasons for a patient to visit their doctor, with one study showing roughly 50% of primary care visits related to a pain complaint. Prescriptions for opioids increased over the 1990s and 2000s, peaking in 2012 and decreasing since, though there remain pockets of high opioid dispensing rates scattered throughout America. As opioid use has become more ubiquitous, the death rate from drug overdoses has also increased steadily, with a sharp rise in deaths during the COVID pandemic. In recent years federal and local governments have attempted to address these worrisome trends with improved funding for resources for the treatment of opioid use disorder, and prevention strategies such as guidelines to help clinicians who prescribe opioids. Following the publication of the 2016 CDC guidelines for prescribing opioids, there was a sharp decrease in opioid prescriptions, with the dispensing rate falling to its lowest level in 15 years. The CDC has recently announced updates to its opioid prescribing guideline and has issued 12 key recommendations and 5 guiding principles to aid in implementation.
Guiding Principles
- Acute (< 1 month), subacute (1 to 3 months), and chronic pain (> 3 months) should be assessed and treated regardless of whether opioids are part of the treatment regimen
- Recommendations are voluntary and are intended to be flexible with individualized patient-centered care
- Following the 2016 CDC guideline publication there were several studies that demonstrated harm to patients due to provider rigidity over prescribing opioid pain medications, including “untreated and undertreated pain, serious withdrawal symptoms, worsening pain outcomes, psychological distress, overdose, and suicidal ideation and behavior”
- Use a multimodal and multidisciplinary approach to pain management including behavioral health and social support systems
- Avoid misapplying the guideline beyond its intended use or implementing policies derived from the guideline that may lead to harm or untreated pain
- Clinicians and health systems should be especially vigilant regarding healthcare inequities in prescribing pain medications
- Groups with highest rate of death from drug overdose: American Indian men | Alaska Native men | Black men
- In one study examining Medicare beneficiaries with disability, the annual prevalence of prescription opioid receipt was similar among Black and White patients, but Black patients received 36% fewer MME (Morphine Milligram Equivalent).

Note: The CDC excludes certain groups from the below recommendations, including those below the age of 18, and pain management related to sickle cell disease, cancer-related pain treatment, palliative care, and end-of-life care.
Key Recommendations
Initiating Opioids for Pain
- Prior to prescribing any opioids
- Clinicians should review the patient’s history of opioid use via the state prescription drug monitoring program (PDMP)
Acute Pain
- Nonopioid therapies are at least as effective as opioids for many common types of acute pain
- Nonopioid pharmacologic and nonpharmacologic therapies should be maximized prior to initiating opiates for acute pain
- Opioids for acute pain should only be given when benefits outweigh risks
- Risks of opioid use and possible benefits should be discussed with patient
- Acute Pain conditions where nonopioid therapy has been shown to be as effective include
- Low back pain | Neck pain | Minor MSK injuries | Minor surgeries | Kidney stones | Migraine
- Nonpharmacologic therapies include
- Ice | Heat | Elevation | Rest | Immobilization | Exercise | Massage
- Nonopioid Pharmacologics include
- Tylenol | NSAIDs | Menthol gel | Triptans | Muscle relaxants
Subacute and Chronic Pain
- Nonopioid therapies are preferred for subacute and chronic pain
- Maximize use of nonpharmacologic and nonopioid pharmacologic therapies as appropriate
- Consider initiating opioid therapy if benefits outweigh risks
- Discuss risks and benefits with patient
- Establish treatment goals | Make a plan to discontinue if benefits don’t outweigh the risks
- Nonpharmacologic therapies include
- Physical therapy | Weight loss | Psychological therapy | Spinal manipulation | Low-level laser therapy | Massage | Acupuncture | Cognitive behavior therapy | Mindfulness practices
- Nonopioid Pharmacologics include Topical NSAIDS | SNRIs | Tricyclics | Gabapentin | Pregabalin | Capsaicin | Lidocaine patches
NSAID Use
NSAIDs should be used at the lowest effective dose and shortest duration needed and should be used with caution, particularly in older adults and in patients with cardiovascular comorbidities, chronic renal failure, or previous gastrointestinal bleeding
Opioid Drug and Dose Selection
- When starting opioids for all pain types (Acute | Subacute | Chronic), begin with immediate release formulations
- Extended release/long-acting (ER/LA) opioids should be reserved for severe, continuous pain
- Some ER/LA opioids should be reserved for opioid-tolerant patients (Methadone | Fentanyl)
- Initiate the immediate release opioids at the lowest effective dosage for opioid-naïve patients
- Approximately 5 to 10 MME or a daily dosage of 20 to 30 MME/day
- If opioids are continued use caution
- Carefully evaluate individual benefits and risks when considering increasing dosage
- Avoid increasing dosage above levels likely to yield limited benefits with greater risks
- Doses ≥ 50 MME/day yield diminishing returns and progressively increasing risks which should be discussed with patient and carefully considered
- Once on opioid therapy, clinicians should carefully weigh benefits and risks when changing opioid dosage
- Patients who are at higher risk for adverse events
- Sleep apnea | Hepatic dysfunction | CKD/ESRD | Pregnancy | Substance use disorder | >65 years | Work in Safety Critical Jobs | Mental health disorders | Prior overdose
- If benefits do not outweigh risks of continued opioid therapy, optimize other therapies while working to gradually taper to lower dosages or appropriately taper and discontinue opioids
- Patient agreement is vitally important for a successful taper
- Reasons to taper include
- Patient request | Pain has improved and underlying cause may have resolved | Misuse | Development of comorbidities that increase risks from opioid use | Side effects diminish quality of life | Side effects impair function | Ongoing therapy has not improved pain | Overdose or serious adverse event has occurred
- Tapers of approximately 10% per month or slower are likely to be better tolerated when patients have been taking opioids for longer durations (≥ 1 year)
- Tapers of 10% per week may be tolerated for those on opioids for shorter durations (weeks to months)
- Do not abruptly discontinue or rapidly reduce to low doses unless there are indications of a life-threatening issue such as concern for impending overdose (e.g., confusion, sedation, slurred speech)
- Risks of abrupt withdrawal of opiates include: Acute withdrawal symptoms | Exacerbation of pain | Serious psychological distress | Suicidal ideation
Duration and Follow Up
Acute Pain
- Prescriptions dispensed for acute pain should contain only enough opioids for the expected duration of pain severe enough to require opioids
- For many causes of acute pain an initial opioid prescription of 4 to 7 days’ duration is sufficient
- Reevaluate and rule out other causes of pain if patient continues to need opioids for >2 weeks for acute pain
Subacute and Chronic Pain
- Reevaluate benefits and risks with patients within 1 to 4 weeks of starting or adjusting dosage of opioid therapy
- Interval for follow up after initiating or adjusting opioids should be shorter if
- Receiving > 50 MME/day | Starting methadone | Starting ER/LA opioids
- For patients on long term opioids follow up is recommended at least every 3 months
Risk Assessment
- Periodically during follow up
- Rediscuss risks of opioids with patient | Check PDMP to review dosages of opioids received | Discuss strategies to mitigate risk | Offer Naloxone (FDA approved OTC Naloxone spray March 2023)
- Consider using toxicology testing annually “to assess for prescribed opioids and other prescription and nonprescription controlled substances that increase risk for overdose when combined with opioids”
- Results should be used in a non-punitive manner and testing discussed prior to being undertaken with the patient
- Use caution when prescribing opioid pain medication and benzodiazepines together
- Consider tapering off benzos prior to initiating opioids
- Offer or arrange treatment with evidence-based medications to treat patients with opioid use disorder
- Opioid use disorder definition
- Defined by the DSM-5 (see ‘Primary Sources – Learn More’ below)
- FDA approved medication for opioid use disorder include
- Buprenorphine| Methadone | Naltrexone

ACP Guideline: Colonoscopy and Interventions to Prevent Recurrence Following Left-Sided Diverticulitis
Summary:
Diverticula are sac-like protrusions of the colonic wall that tend to occur at increasing rates with older age, with an estimated 50% of adults over the age of 60 developing diverticula. Diverticulosis is defined as the presence of diverticula, and 5 to 10% of patients with diverticulosis will go on to develop symptomatic disease such as diverticulitis, recurrent pain, and bleeding. Following an episode of diverticulitis, a recurrence will occur in 8% to 36% of patients at 1 to 10 years. Additionally, patients who present with complicated diverticulitis – or diverticulitis associated with abscess, bleeding, obstruction, fistula or perforation – have a higher prevalence of colorectal cancer that may be misdiagnosed or missed on initial imaging. The ACP has put together recommendations regarding follow up care after an episode of left-sided diverticulitis given these increased risks.
Definitions:
Uncomplicated Diverticulitis
- Left lower quadrant abdominal pain and change in bowel habits associated with localized inflammation of diverticula
- No signs or symptoms of sepsis
- Immunocompetent patients
Complicated Diverticulitis
- Diverticulitis with at least one of the following: Perforation | Bleeding | Obstruction | Abscess/Phlegmon | Fistula | Immunosuppressed patient
Colonoscopy for Diagnostic Evaluation:
“ACP suggests that clinicians refer patients for a colonoscopy after an initial episode of complicated left-sided colonic diverticulitis in patients who have not had recent colonoscopy”
- Evidence is inconclusive on whether there is a net benefit in obtaining colonoscopy following uncomplicated diverticulitis
- Evidence is also inconclusive on whether there is improved CRC mortality with colonoscopy following complicated diverticulitis
- Despite this, ACP recommends colonoscopy following complicated diverticulitis in patients with no recent colonoscopy to rule out CRC given that CRC may present with similar signs and symptoms to complicated diverticulitis
- Colonoscopy should be obtained at least 6 to 8 weeks after resolution of diverticulitis
- ACP does not define “recent colonoscopy”, but they do not recommend colonoscopy for patients who are otherwise up to date on their CRC screening
- Colonoscopy may be most beneficial for those at higher risk of CRC: Older age | Malnutrition | Weight loss | Change in bowel habits | Bloody stool | Persistent abdominal pain
Interventions to Prevent Recurrence:
“ACP recommends against clinicians using mesalamine to prevent recurrent diverticulitis”
- Diverticulitis is believed to be an inflammatory process, so there was interest in using anti-inflammatory medications to prevent recurrence
- Studies reviewed showed no benefit and more discontinuation of drug due to adverse events with mesalamine use
Dietary Interventions
- ACP did not review studies on dietary therapies (e.g. high fiber diet) for reduction of recurrent diverticulitis
- A large study in 2008 demonstrated no increased risk for diverticulitis with a diet including nuts, corn, and popcorn, despite the persistence of this belief in the medical community (see
Primary Sources – Learn More below)
“ACP suggests that clinicians discuss elective surgery to prevent recurrent diverticulitis after initial treatment in patients who have either uncomplicated diverticulitis that is persistent or recurs frequently or complicated diverticulitis. The informed decision whether to undergo surgery should be personalized based on a discussion of potential benefits, harms, costs, and patient’s preferences”
- Elective surgery should not be offered to patients with uncomplicated diverticulitis that is not persistent or recurring
- Discussion of surgery should include potential harms as 1.4% to 5.5% of surgical patients develop post-op complications (e.g. anastomotic leak, sepsis, MI)
- There is no minimum number of recurrences necessary for surgery and discussion should be tailored to the individual patient
- Evidence did show decreased rate of recurrent diverticulitis with surgery for patients with:
- Complicated or uncomplicated diverticulitis with long term symptoms following acute episode (> 3 months of symptoms)
- Complicated or uncomplicated diverticulitis with high rate of recurrence (> or = 3 over 2 years)

Screening for Sexually Transmitted Infections – Who, When and How Often?
SYNOPSIS:
There are an estimated 2.8 million new chlamydia infections each year in the US and 1.5 million new cases of gonorrhea diagnosed. The highest rates of both gonorrhea and chlamydia are reported in women aged 15 to 24. Symptoms are vague and sequelae can include pelvic inflammatory disease, ectopic pregnancy and infertility. A full comprehensive sexual history may identify other risk factors to prompt more comprehensive screening for sexually transmitted infections
CLINICAL ACTIONS:
Sexually transmitted infections (STIs) are common with potential for serious long term outcomes, and remain a serious public health concern. Here, we outline the recommendations for screening for STIs by population:
General Population
Gonorrhea and Chlamydia
- Annual screening for gonorrhea and chlamydia is recommended for all sexually active women <25 years | evidence is insufficient for routine testing of gonorrhea and chlamydia in heterosexual men, consider screening young men in high prevalence clinical settings e.g. adolescent clinics, correctional facilities, STI/sexual health clinic
- Re-testing is recommended 3 months after treatment due to high re-infection rates
- Screening is recommended for adults >25 years old at increased risk for infection (new partner, multiple partners, or a partner who has an STI)
- Consider testing for rectal chlamydia and pharyngeal gonorrhea based on sexual history practices
- Annual testing is recommended for men who have sex with men (MSM) at sites of contact (urethra, rectum)and every 3-6 months if at higher risk e.g. MSM on pre-exposure prophylaxis (PrEP), HIV infection, or if they or their sex partners have multiple partners
- Transgender and Gender Diverse Persons screening adapted based on anatomy
The USPSTF 2021 Update: Chlamydia and Gonorrhea Screening
…recommends screening for chlamydia in all sexually active women 24 years or younger and in women 25 years or older who are at increased risk for infection. (B recommendation)
…recommends screening for gonorrhea in all sexually active women 24 years or younger and in women 25 years or older who are at increased risk for infection. (B recommendation)
The USPSTF concludes that the current evidence is insufficient to assess the balance of benefits and harms of screening for chlamydia and gonorrhea in men
Syphilis
- Screening for syphilis is based on risk profile, with higher risk including history of incarceration, transactional sex work, geography, or male younger than 29 years old
- Annual screening for sexually active MSM | 3 to 6 months if at increased risk
- Annual screening for syphilis is recommended in transgender and gender diverse persons
HSV
- Consider type-specific HSV serologic testing in patients presenting for an STI evaluation (especially if multiple partners)
Note: USPSTF “recommends against routine serologic screening for genital HSV infection in asymptomatic adolescents and adults, including those who are pregnant”
Trichomonas
- Consider screening for trichomonas in high-prevalence settings or patients at higher risk for infection (multiple sex partners, transactional sex, drug misuse, or a history of STI or incarceration)
Hepatitis B
- Screen all adults aged ≥18 years at least once during a lifetime (CDC recommendation)
- Use triple Panel: 3 main serologic markers used to determine HBV infection status
- Hepatitis B surface antigen (HBsAg) | Antibody to hepatitis B surface antigen (anti-HBs) | Antibody to hepatitis B core antigen (anti-HBc)
- Test individuals with a history of risk for HBV infection, regardless of age, if they might have been susceptible during the period of risk
- Susceptible persons include those who have never been infected with HBV (i.e., total anti-HBc negative) and either did not complete a HepB vaccine series per ACIP recommendations or who are known vaccine nonresponders
- Periodically test susceptible persons, regardless of age, who have ongoing risk | Offer testing if the risk for exposure occurred after previous HBV serologic testing and while the person was susceptible
- CDC expands risk-based testing recommendations to the following populations
- Activities, exposures, or conditions associated with increased risk for HBV infection
- Persons incarcerated or formerly incarcerated in a jail, prison, or other detention setting
- Persons with a history of STIs or multiple sex partners
- Persons with a history of hepatitis C virus infection
- Offer testing to anyone who requests HBV testing
Hepatitis C
- Screening for hepatitis C infection (HCV) should take include all adults over age 18 years except in settings with HCV positivity < 0.1%
- All persons with risk factors (eg., persons with HIV, prior recipients of blood transfusions, persons who ever injected drugs and shared needles, and persons who are born to an HCV-infected mother) should be tested for HCV, with periodic testing while risk factors persist
HIV
- Screening for HIV should be performed in all individuals aged 15 to 65 | Younger adolescents and older adults who are at increased risk of infection should also be screened
- Annual HIV screening is recommended for MSM with more than one sexual partner, with consideration for more frequent 3-6 month intervals for testing
- The USPSTF recommends screening for HIV in all pregnant persons, including those who present in labor or at delivery whose HIV status is unknown
- People who are at increased risk for HIV should be screened at least annually
- People who inject drugs and their sex partners
- People who exchange sex for money or drugs
- Sex partners of people with HIV
- Sexually active gay, bisexual, and other men who have sex with men (more frequent testing may be beneficial [e.g., every 3–6 months])
- Heterosexuals who themselves or whose sex partners have had ≥1 sex partner since their most recent HIV test
- People receiving treatment for hepatitis, tuberculosis, or STIs
Persons Living With HIV
- At first HIV evaluation and annually afterwards, screen for
- Gonorrhea
- Chlamydia
- Syphilis
- Hepatitis B surface antigen and Hepatitis B immunity
- Hepatitis C screening for all persons with HIV and subsequent annual testing for MSM
- Specifically for women with HIV
- Screen for trichomonas for women at first evaluation and annually afterwards
- Women should be screened within 1 year of sexual activity with testing repeat 65 months later | 3 normal and consecutive pap tests, screening can be spaced out to every 3 years
- For pregnant women: repeat testing during the third trimester in women with risk factors and in women living or receiving care in high-incidence settings who had a negative test result earlier in pregnancy | CDC notes that repeat testing in the third trimester may be considered for all women with a negative test result early in pregnancy
KEY POINTS:
- Screen sexually active women ≥25 for gonorrhea and chlamydia if at increased risk
- More comprehensive screening for STIs include evaluation for trichomonas, syphilis, HIV, Hepatitis B and Hepatitis C
- CDC has updated guidelines to recommend universal Hepatitis C and Hepatitis B screening in all adults

Patient with Stable CVD: Rivaroxaban, Aspirin or Both to Prevent Recurrent Events?
BACKGROUND AND PURPOSE:
- Aspirin reduces risk of major CV events by 19% and CV death by 9% in those with CVD
- 5 to 10% of patients will still have recurrent CV events
- Eikelboom et al. (NEJM, 2017) assessed whether rivaroxaban, aspirin or both is most effective for secondary cardiovascular event prevention in those with stable atherosclerotic vascular disease
METHODS:
- Cardiovascular Outcomes for People Using Anticoagulation Strategies (COMPASS) trial
- 602 centers in 33 countries
- Double-blind randomized controlled (RCT) trial
- Inclusion criteria: Coronary artery disease, peripheral arterial disease, or both
- Participants were randomly assigned to 1 of 3 cohorts
- Rivaroxaban (2.5 mg twice daily) plus aspirin (100 mg once daily)
- Rivaroxaban (5 mg twice daily)
- Aspirin (100 mg once daily)
- Primary outcome
- Composite of cardiovascular death, stroke, or myocardial infarction
- The study was stopped short at 23 month follow-up, due to superiority of the rivaroxaban and aspirin group
RESULTS:
- Comparing to aspirin-alone group, the rivaroxaban-plus-aspirin group had
- Fewer patients (4.1% vs 5.4%) with adverse cardiovascular events (hazard ratio [HR] 0.76; 95% CI 0.66 to 0.86; P<0.001)
- More major bleeding events occurred (3.1% vs 1.9% HR 1.70; 95% CI 1.40 to 2.05; P<0.001)
- Most major bleeding was into the gastrointestinal tract
- There was no significant difference in intracranial bleeding, fatal bleeding or bleeding into a critical organ
- There were 313 deaths (3.4%) in the rivaroxaban-plus-aspirin group as compared with 378 (4.1%) in the aspirin-alone group ([HR] 0.82; 95% CI 0.71 to 0.96; P=0.01; threshold P value for significance, 0.0025)
- When comparing rivaroxaban-alone group than in the aspirin-alone group, there was no significant difference in primary outcome but there were more major bleeding events
CONCLUSION:
- Rivaroxaban-plus-aspirin had better cardiovascular outcomes compared to aspirin alone
- Rivaroxaban alone did not impact outcomes and had more major bleeding events than aspirin alone
