Pre-exposure prophylaxis (PrEP) is an important biomedical human immunodeficiency virus (HIV) prevention tool gaining more popularity among Parisian men who have sex with men (MSM) who engage in transactional sex. This study examines the knowledge of, and willingness to use, different modalities of PrEP among this subgroup. Broadcast advertisements were placed on a geosocial-networking smartphone application with a link to a Web-based survey during three 24-hour periods in October 2016. Modified Poisson regression models were used to assess the association between engagement in transactional sex and preferences for each of these PrEP modalities. A total of 444 respondents were included. About 14% reported engagement in transactional sex. In all, 90% of MSM who engaged in transactional sex were knowledgeable of daily oral PrEP, while 13.3% were knowledgeable about long-acting injectable PrEP or penile or rectal microbicides. They were more likely to be aware of long-acting injectable PrEP (aRR = 2.52, 95% CI = 1.16 to 5.47) and willing to use daily oral PrEP (aRR = 1.48; 95% CI = 1.11 to 1.98) or long-acting injectable PrEP (aRR = 1.40; 95% CI = 1.09 to 1.81) than MSM who had not engaged in transactional sex. Long-acting injectable PrEP may be an important HIV-prevention option for MSM who engage in transactional sex if this modality is proven effective.

Rectal douching is a common but potentially risky practice among MSM; MSM who douche may be ideal candidates for rectal microbicides as HIV prevention. Herein we explored rectal douching and its association with condomless receptive anal intercourse (CRAI), group sex, rates of HIV and other STIs, and likelihood to use rectal microbicide gels. We recruited a sample of 580 MSM from a geosocial-networking smartphone application in Paris, France in 2016. Regression models estimated adjusted risk ratios (aRRs) for associations between rectal douche use and (1) engagement in CRAI, (2) group sex, (3) self-reported HIV and STI diagnoses, and (4) likelihood to use rectal microbicide gels for HIV prevention. 54.3% of respondents used a rectal douche or enema in the preceding 3 months. Douching was significantly associated with CRAI (aRR: 1.77), participation in group sex (aRR: 1.42), HIV infection (aRR: 3.40), STI diagnosis (aRR: 1.73), and likelihood to use rectal microbicide gels (aRR: 1.78). Rectal douching is common among MSM, particularly those who practice CRAI, and rectal microbicide gels may be an acceptable mode of HIV prevention for MSM who use rectal douches.

This case report describes the development of withdrawal from phenibut, a gamma-aminobutyric acid-receptor type B agonist. Although phenibut is not an FDA-approved medication, it is available through online retailers as a nootropic supplement. There are reports of dependence in patients that misuse phenibut. We report a case in which a patient experienced withdrawal symptoms from phenibut and was successfully treated with a baclofen taper. This case report highlights the development of phenibut use disorder with coingestion of alcohol and potential management for phenibut withdrawal. We believe clinicians must be aware of how phenibut dependence may present and how to manage the withdrawal syndrome.

Primary cardiac tumors are a rare set of benign and malignant neoplasms found in the heart or pericardium. We describe a patient presenting with nonspecific symptoms and ultimately diagnosed with primary cardiac non-Hodgkin's lymphoma (PCL). Our patient had extensive tumor in the right ventricle, which extended into the right atrium and right ventricular outflow tract. The tumor also encased the right coronary artery, which manifested as ischemic changes on EKG and cardiac MRI. The patient was treated with chemotherapy and achieved complete remission, with dramatic and full resolution of the mass on repeat echocardiography in nine weeks. More studies are needed to understand the optimal management and prognosis of patients with PCL.

OBJECTIVE:Among chronic hemodialysis patients, hyperphosphatemia is common and associated with mortality. Behavioral economics and complementary behavior-change theories may offer valuable approaches to achieving phosphorus (PO4) control. The aim was to determine feasibility of implementing financial incentives and structured coaching to improve PO4 in the hemodialysis setting. DESIGN AND METHODS/METHODS:This pilot randomized controlled trial was conducted in 3 urban dialysis units for 10 weeks among 36 adults with elevated serum PO4 (median >5.5 mg/dL over 3 months). INTERVENTIONS/METHODS:Twelve participants each were randomized to: (1) financial incentives for lowering PO4, (2) coaching about dietary and medication adherence, or (3) usual care. PO4 was measured during routine clinic operations. Each incentives arm participant received the equivalent of $1.50/day if the PO4 was ≤5.5 mg/dL or >5.5 mg/dL but decreased ≥0.5 mg/dL since the prior measurement. The coach was instructed to contact coaching arm participants at least 3 times per week. MAIN OUTCOME MEASURES/METHODS:The outcome measures included: (1) enrollment rate, (2) dropout rate, and (3) change in PO4 from beginning to end of 10-week intervention period. RESULTS:Of 66 eligible patients, 36 (55%) enrolled. Median age was 53 years, 83% were black race, and 78% were male. Median baseline PO4 was 6.0 (interquartile range 5.6, 7.5). Using stratified generalized estimation equation analyses, the monthly decline in PO4 was -0.32 mg/dL (95% CI -0.60, -0.04) in the incentives arm, -0.40 mg/dL (-0.60, -0.20) in the coaching arm, and -0.24 mg/dL (-0.60, 0.08) in the usual care arm. No patients dropped out. All intervention arm participants expressed interest in receiving similar support in the future. CONCLUSIONS:This pilot trial demonstrated good feasibility in enrollment and implementation of novel behavioral health strategies to reduce PO4 in dialysis patients.

AIM/OBJECTIVE:To characterize defibrillation and cardiac arrest survival outcomes in movies. METHODS:Movies from 2003 to 2012 with defibrillation scenes were reviewed for patient and rescuer characteristics, scene characteristics, defibrillation characteristics, additional interventions, and cardiac arrest survival outcomes. Resuscitation actions were compared with chain of survival actions and the American Heart Association (AHA) Emergency Cardiovascular Care (ECC) 2020 Impact Goals. Cardiac arrest survival outcomes were compared with survival rates reported in the literature and targeted by the AHA ECC 2020 Impact Goals. RESULTS:Thirty-five scenes were identified in 32 movies. Twenty-five (71%) patients were male, and 29 (83%) rescuers were male. Intent of defibrillation was resuscitation in 29 (83%) scenes and harm in 6 (17%) scenes. Cardiac arrest was the indication for use in 23 (66%) scenes, and the heart rhythm was made known in 18 scenes (51%). When the heart rhythm was known, defibrillation was appropriately used for ventricular tachycardia or ventricular fibrillation in 5 (28%) scenes and inappropriately used for asystole in 7 (39%) scenes. In 8 scenes with in-hospital cardiac arrest, 7 (88%) patients survived, compared to survival rates of 23.9% reported in the literature and 38% targeted by an AHA ECC 2020 Impact Goal. In 12 movie scenes with out-of-hospital cardiac arrest, 8 (67%) patients survived, compared to survival rates of 7.9-9.5% reported in peer-reviewed literature and 15.8% targeted by an AHA ECC 2020 Impact Goal. CONCLUSION/CONCLUSIONS:In movies, defibrillation and cardiac arrest survival outcomes are often portrayed inaccurately, representing missed opportunities for public health education.

Case reports of kidney transplantation using HIV-positive (HIV+) donors in South Africa and advances in the clinical care of HIV+ transplant recipients have drawn attention to the legal prohibition of transplanting organs from HIV+ donors in the United States. For HIV+ transplant candidates, who face high barriers to transplant access, this prohibition violates beneficence by placing an unjustified limitation on the organ supply. However, transplanting HIV+ organs raises nonmaleficence concerns given limited data on recipient outcomes. Informed consent and careful monitoring of outcome data should mitigate these concerns, even in the rare circumstance when an HIV+ organ is intentionally transplanted into an HIV-negative recipient. For potential donors, the federal ban on transplanting HIV+ organs raises justice concerns. While in practice there are a number of medical criteria that preclude organ donation, only HIV+ status is singled out as a mandated exclusion to donation under the National Organ Transplant Act (NOTA). Operational objections could be addressed by adapting existing approaches used for organ donors with hepatitis. Center-specific outcomes should be adjusted for HIV donor and recipient status. In summary, transplant professionals should advocate for eliminating the ban on HIV+ organ donation and funding studies to determine outcomes after transplantation of these organs.
