Background. Paired with other active antiretrovirals (ARVs), fostemsavir (FTR) may offer heavily treatment-experienced (HTE) people with HIV (PWH) options for continuing effective treatment. Durability and effectiveness of FTR-containing regimens in routine clinical care in the United States were assessed. Methods. Electronic health record data from the OPERA cohort were used to identify adults initiating FTR-containing regimens between 2JUL2020 (FDA approval) and 1SEP2021. Eligible PWH were followed from first FTR prescription (baseline) until FTR discontinuation, death, loss to follow up, or study end (28FEB2022). Durability was assessed as frequency of FTR discontinuation. Virologic outcomes assessed at 6 and 12 months (+/-3 months) included suppression (viral load [VL] < 50 copies/mL), virologic failure (2 consecutive VL >=200 copies/mL or 1 VL >=200 copies/ mL + FTR discontinuation within 120 days after suppression), and viral blips (1 VL >=50 copies/mL preceded and followed by VLs < 50 copies/mL). Analyses were stratified by baseline viral load (bVL < 50 copies/mL; bVL >=50 copies/mL). Results. Overall, 86 PWH initiated FTR (bVL < 50: 30; bVL >=50: 55), with median follow up of 10.8 months (IQR: 6.8, 15.3). Compared to PWH with bVL >=50, those with bVL < 50 were older and more likely to be white and have lived longer with HIV (Table 1). Over follow up, 20% discontinued FTR (Table 2). Most (82%) FTR discontinuations were switches to alternative regimens; the remaining were ARV interruptions (no ARVs for > 45 days). Among PWH with bVL < 50, most maintained suppression (6 months: 74%; 12 months: 82%; Figure). Among PWH with bVL >=50 and with follow up VL during the period assessed, 33% were suppressed at 6 months, 36% were suppressed at 12 months, and 48% achieved suppression at any time over the entire follow up (Figure). In either group, <=5 PWH experienced virologic failure or blip, though the proportion of PWH with multiple follow up VLs was low. Conclusion. Despite a heterogenous population and diverse regimens, most HTE PWH remained on FTR at study end. Most PWH with bVL < 50 remained suppressed and half of PWH with bVL >=50 achieved suppression over the entire study period. Virologic failure and blips were infrequent, although follow up was limited in this early evaluation of real-world FTR use

BACKGROUND/UNASSIGNED:Nonadherence to antihypertensive medications remains a persistent problem that leads to preventable morbidity and mortality. Behavioral economic strategies represent a novel way to improve antihypertensive medication adherence, but remain largely untested especially in vulnerable populations which stand to benefit the most. The Behavioral Economics Trial To Enhance Regulation of Blood Pressure (BETTER-BP) was designed in this context, to test whether a digitally-enabled incentive lottery improves antihypertensive adherence and reduces systolic blood pressure (SBP). DESIGN/UNASSIGNED:BETTER-BP is a pragmatic randomized trial conducted within 3 safety-net clinics in New York City: Bellevue Hospital Center, Gouveneur Hospital Center, and NYU Family Health Centers - Park Slope. The trial will randomize 435 patients with poorly controlled hypertension and poor adherence (<80% days adherent) in a 2:1 ratio (intervention:control) to receive either an incentive lottery versus passive monitoring. The incentive lottery is delivered via short messaging service (SMS) text messages that are delivered based on (1) antihypertensive adherence tracked via a wireless electronic monitoring device, paired with (2) a probability of lottery winning with variable incentives and a regret component for nonadherence. The study intervention lasts for 6 months, and ambulatory systolic blood pressure (SBP) will be measured at both 6 and 12 months to evaluate immediate and durable lottery effects. CONCLUSIONS/UNASSIGNED:BETTER-BP will generate knowledge about whether an incentive lottery is effective in vulnerable populations to improve antihypertensive medication adherence. If successful, this could lead to the implementation of this novel strategy on a larger scale to improve outcomes.

Objectives UpRi is a first-in-class NaPi2b ADC with a novel scaffold-linker-payload that enables high drug-to-antibody ratio and controlled bystander effect. NaPi2b is a sodium-dependent phosphate transporter protein broadly expressed in high-grade serous ovarian cancer (HGSOC), with limited expression in healthy tissues. Interim data from the Phase 1b expansion cohort of heavily pretreated patients with recurrent HGSOC has been reported. These data demonstrated clinically meaningful activity, notably in patients with NaPi2b-high tumors (TPS>=75). Effective and well-tolerated treatments for PROC remains an unmet medical need. The standard of care, singleagent chemotherapy, has limited efficacy, significant toxicities, and short duration of response. UPLIFT was designed as a single- arm Ph2 registrational trial for UpRi monotherapy in PROC. Methods UPLIFT is enrolling patients with PROC with up to 4 prior LoT. Prior bevacizumab is required for patients with 1-2 prior LoT only; it's not required for patients with 3-4 prior LoT. Patients may enroll regardless of NaPi2b expression; <= Grade 2 peripheral neuropathy is permitted. Primary platinum refractory patients are excluded. UPLIFT will enroll ~180 patients globally, including ~100 patients with high NaPi2b expression. UpRi is dosed IV at 36 mg/ m2 up to ~80 mg dose maximum Q4W. Baseline tumor samples (fresh or archived) will be collected for central analysis of NaPi2b expression. The primary endpoint is ORR in NaPi2b-high expressing patients. The cut-off for high NaPi2b expression is TPS>=75. Secondary endpoints include ORR in the overall population, duration of response, and safety. UPLIFT is conducted in collaboration with ENGOT (ENGOT-ov67) and GOG (GOG-3048). NCT03319628 Results trialinprogress Conclusions trialinprogress

BACKGROUND:Current guidelines suggest antibiotics prophylaxis is not necessary for patients with orthopedic prosthetics undergoing gastrointestinal endoscopy. Clinical evidence to support this recommendation is lacking. AIMS/OBJECTIVE:To analyze the association between inpatient gastrointestinal endoscopy and prosthetic joint infection (PJI) in patients with a recent arthroplasty. METHODS:We included patients admitted from July to October of each calendar year (index admissions) who had an arthroplasty in the same calendar year prior to the index admission. We followed the occurrence of PJI for 60 days after the index admission. Only admissions from July to October were chosen as index admissions, and the follow-up period was limited to 60 days because the database structure prohibits the analysis of events in different calendar years. We compared the rate of 60-day PJI between those who had gastrointestinal endoscopy on index admissions to those who had not. We excluded patients aged less than 18 years, who died on index admission, or had any infection in the same calendar year before or during the index admission. RESULTS:Of 1,831,218 patients with arthroplasty, 88,345 met the inclusion criteria, out of which 5,855 had gastrointestinal endoscopy. The rate of 60-day PJI in those who had endoscopy was 0.23%, and in those who had not was 0.52% (P < 0.001). EGD without excision (adjusted odds ratio [95% confidence interval]: 0.20 [0.03-1.42], P = 0.107), EGD with excision (0.58 [0.21-1.60], P = 0.295), colonoscopy without excision (0.43 [0.11-1.72], P = 0.233), colonoscopy with excision (0.31 [0.04-2.21], P = 0.241), and PEG/PEJ (0.38 [0.05-2.71], P = 0.337) were not associated with risk of 60-day PJI. We found no PJI cases in patients underwent esophageal dilation, ERCP, and EUS with FNA. CONCLUSIONS:Gastrointestinal endoscopy in hospitalized patients with a recent previous arthroplasty is not associated with an increased risk of 60-day prosthetic joint infection.

Background. HIV-associated wasting (i.e., progressive, involuntary weight loss with both fat and lean tissue loss; HIVAW) is an under-appreciated AIDS-defining illness; the 2012-2018 period prevalence was reported as 18% in a recent claims study in the United States. We aimed to assess the association between incident HIVAW/ low weight and all-cause mortality in the era of modern combination antiretroviral therapy (ART). Methods. In the Observational Pharmaco-Epidemiology Research & Analysis (OPERA) cohort, PWH without (a) any prior HIVAW/low weight, (b) malignancy within 3 years, and (c) opportunistic infection within 1 year who were active in care between 2016 and 2020 were followed through death, loss to follow-up, or study end (31OCT2021). HIVAW/low weight included a wasting or low BMI/underweight diagnosis (ICD codes, title search) or BMI < 20 kg/m2. Hazard ratios (HR) and 95% confidence intervals (CI) for the association between time-dependent incident HIVAW/low weight (exposure) and all-cause mortality (outcome) were estimated with extended Cox regression models. The adjusted model included age at baseline, race, ethnicity, and time-dependent covariates (log10 viral load, Veterans Aging Cohort Study [VACS] Mortality Index score). Viral load and VACS score were included as surrogate markers for ART use and comorbidities, respectively. Linear and quadratic terms of continuous variables were included. Results. Of 67,119 PWH without prior HIVAW/low weight in OPERA, 62,314 (93%) PWH had non-missing covariate data and were included in the models; baseline characteristics did not differ between the full and model study populations (Table 1). Over a median follow-up of 45 months (interquartile range: 27, 65), there were 4,755 (8%) cases of incident HIVAW/low weight and 1,354 (2%) deaths. In the adjusted model, PWH who experienced incident HIVAW/low weight had a significantly increased risk of death over follow-up than those who did not experience HIVAW/low weight (HR: 1.96; 95% CI: 1.68, 2.27) (Table 2). Conclusion. In this analysis of 62,314 PWH in care, incident HIVAW/low weight was associated with twice the risk for all-cause mortality in the modern ART era. Particular attention needs to be paid to HIVAW/low weight among PWH to restore health and potentially reduce the risk of death

Background: There is currently a paucity of data on urethral-related outcomes in metoidioplasty and phalloplasty gender affirming surgery (MaPGAS) with urethral lengthening (UL)and vaginectomy.
Method(s): A systematic review was performed utilizing MEDLINE, Web of Science, Cochrane Library, Europe PMC, OSF Preprints, and EMBASE. Methodologic quality was scored using Methodological Index for Non-Randomized Studies (MINORS) criteria. Four independent reviewers performed the article evaluation, data extraction, and methodologic quality assessment. Primary outcomes included standing to urinate/pee (STP), penile length, glanular meatus, urethral stricture, fistula, and flap necrosis. Results were summarized qualitatively with descriptive statistics.
Result(s): A total of 2,881 articles of which 11 retrospective reviews of 13 cohorts met criteria; 4.3/16 average (avg) MINORS score. Six metoidioplasty cohorts had an average penile length of 6 cm, 74% reported successful STP, and a quarter developed stricture or fistula. Phalloplasty cohorts included radial forearm flap (RF) and Anterolateral Thigh flap (ALT). Of the 4 RF studies nearly a third developed a stricture or fistula and only one study reported 99% STP with a glanular meatus. Three ALT studies reported no length but had 80-90% STP with a glanular meatus and a quarter with stricture or fistula.
Conclusion(s): Urethral complications in MaPGAS-UL in a cohort with prior vaginectomy are common and variably reported. Patient centered outcome measures as well as clearly defined outcome metrics created in partnership with community members are needed.
