IMPORTANCE: Bariatric surgery is the most effective treatment for severe obesity; yet it is unclear whether the long-term safety and comparative effectiveness of these operations differ across racial and ethnic groups. OBJECTIVE: To compare outcomes of Roux-en-Y gastric bypass (RYGB) and sleeve gastrectomy (SG) across racial and ethnic groups in the National Patient-Centered Clinical Research Network (PCORnet) Bariatric Study. DESIGN, SETTING, AND PARTICIPANTS: This was a retrospective, observational, comparative effectiveness cohort study that comprised 25 health care systems in the PCORnet Bariatric Study. Patients were adults and adolescents aged 12 to 79 years who underwent a primary (first nonrevisional) RYGB or SG operation between January 1, 2005, and September 30, 2015, at participating health systems. Patient race and ethnicity included Black, Hispanic, White, other, and unrecorded. Data were analyzed from July 1, 2021, to January 17, 2022. EXPOSURE: RYGB or SG. OUTCOMES: Percentage total weight loss (%TWL); type 2 diabetes remission, relapse, and change in hemoglobin A1c (HbA1c) level; and postsurgical safety and utilization outcomes (operations, interventions, revisions/conversions, endoscopy, hospitalizations, mortality, 30-day major adverse events) at 1, 3, and 5 years after surgery. RESULTS: A total of 36 871 patients (mean [SE] age, 45.0 [11.7] years; 29 746 female patients [81%]) were included in the weight analysis. Patients identified with the following race and ethnic categories: 6891 Black (19%), 8756 Hispanic (24%), 19 645 White (53%), 826 other (2%), and 783 unrecorded (2%). Weight loss and mean reductions in HbA1c level were larger for RYGB than SG in all years for Black, Hispanic, and White patients (difference in 5-year weight loss: Black, −7.6%; 95% CI, −8.0 to −7.1; P < .001; Hispanic, −6.2%; 95% CI, −6.6 to −5.9; P < .001; White, −5.9%; 95% CI, −6.3 to −5.7; P < .001; difference in change in year 5 HbA1c level: Black, −0.29; 95% CI, −0.51 to −0.08; P = .009; Hispanic, −0.45; 95% CI, −0.61 to −0.29; P < .001; and White, −0.25; 95% CI, −0.40 to −0.11; P = .001.) The magnitude of these differences was small among racial and ethnic groups (1%-3% of %TWL). Black and Hispanic patients had higher risk of hospitalization when they had RYGB compared with SG (hazard ratio [HR], 1.45; 95% CI, 1.17-1.79; P = .001 and 1.48; 95% CI, 1.22-1.79; P < .001, respectively). Hispanic patients had greater risk of all-cause mortality (HR, 2.41; 95% CI, 1.24-4.70; P = .01) and higher odds of a 30-day major adverse event (odds ratio, 1.92; 95% CI, 1.38-2.68; P < .001) for RYGB compared with SG. There was no interaction between race and ethnicity and operation type for diabetes remission and relapse. CONCLUSIONS AND RELEVANCE: Variability of the comparative effectiveness of operations for %TWL and HbA1c level across race and ethnicity was clinically small; however, differences in safety and utilization outcomes were clinically and statistically significant for Black and Hispanic patients who had RYGB compared with SG. These findings can inform shared decision-making regarding bariatric operation choice for different racial and ethnic groups of patients.

There are no studies comparing the prognosis for mature T-cell lymphoma (TCL) in people with HIV (PWH) to people without HIV (PWoH) and to AIDS-defining B-cell lymphomas (A-BCLs) in the modern antiretroviral therapy era. North American AIDS Cohort Collaboration on Research and Design and Comprehensive Oncology Measures for Peripheral T-cell Lymphoma Treatment are cohorts that enroll patients diagnosed with HIV and TCL, respectively. In our study, 52, 64, 101, 500, and 246 PWH with histologic confirmation of TCL, primary central nervous system lymphoma, Burkitt’s lymphoma, diffuse large B-cell lymphoma (DLBCL), and Hodgkin’s lymphoma (HL), respectively, and 450 TCLs without HIV were eligible for analysis. At the time of TCL diagnosis, anaplastic large-cell lymphoma (ALCL) was the most common TCL subtype within PWH. Although PWH with TCL diagnosed between 1996 and 2009 experienced a low 5-year survival probability at 0.23 (95% confidence interval [CI]: 0.13, 0.41), we observed a marked improvement in their survival when diagnosed between 2010 and 2016 (0.69; 95% CI: 0.48, 1; P = .04) in contrast to TCLs among PWoH (0.45; 95% CI: 0.41, 0.51; P = .53). Similarly, PWH with ALCLs diagnosed between 1996 and 2009 were associated with a conspicuously inferior 5-year survival probability (0.17; 95% CI: 0.07, 0.42) and consistently lagged behind A-BCL subtypes such as Burkitt’s (0.43; 95% CI:0.33, 0.57; P = .09) and DLBCL (0.17; 95% CI: 0.06, 0.46; P = .11) and behind HL (0.57; 95% CI: 0.50, 0.65; P < .0001). Despite a small number, those diagnosed between 2010 and 2016 experienced a remarkable improvement in survival (0.67; 95% CI: 0.3, 1) in comparison with PWoH (0.76; 95% CI: 0.66, 0.87; P = .58). Thus, our analysis confirms improved overall survival for aggressive B- and T-cell malignancies among PWH in the last decade.

Unhealthy alcohol use among persons living with HIV (PLWH) is linked to significant morbidity, and use of alcohol services may differ by HIV status. Our objective was to compare unhealthy alcohol use screening and treatment by HIV status in primary care. Cohort study of adult (≥18 years) PLWH and HIV‐uninfected participants frequency matched 20:1 to PLWH by age, sex, and race/ethnicity who were enrolled in a large integrated healthcare system in the United States, with information ascertained from an electronic health record. Outcomes included unhealthy alcohol screening, prevalence, provider‐delivered brief interventions, and addiction specialty care visits. Other predictors included age, sex, race/ethnicity, neighborhood deprivation index, depression, smoking, substance use disorders, Charlson comorbidity index, prior outpatient visits, insurance type, and medical facility. Cox proportional hazards models were used to compute hazard ratios (HR) for the outcomes of time to unhealthy alcohol use screening and time to first addiction specialty visit. Poisson regression with robust standard errors was used to compute prevalence ratios (PR) for other outcomes. 11,235 PLWH and 227,320 HIV‐uninfected participants were included. By 4.5 years after baseline, most participants were screened for unhealthy alcohol use (85% of PLWH and 93% of HIV‐uninfected), but with a lower rate among PLWH (adjusted HR 0.84, 95% CI 0.82 to 0.85). PLWH were less likely, compared with HIV‐uninfected participants, to report unhealthy drinking among those screened (adjusted PR 0.74, 95% CI 0.69 to 0.79), and among those who screened positive, less likely to receive brief interventions (adjusted PR 0.82, 95% CI 0.75 to 0.90), but more likely (adjusted HR 1.7, 95% CI 1.2 to 2.4) to have an addiction specialty visit within 1 year. Unhealthy alcohol use was lower in PLWH, but the treatment approach by HIV status differed. PLWH reporting unhealthy alcohol use received less brief interventions and more addiction specialty care than HIV‐uninfected participants. Unhealthy alcohol use can adversely impact people living with HIV (PLWH), but it is unknown if treatment varies by HIV status. We studied alcohol interventions among 11,235 PLWH and 227,320 HIV‐uninfected participants enrolled in a US‐based healthcare system. PLWH reporting unhealthy alcohol use were 18% less likely to have brief interventions in primary care compared with HIV‐uninfected, but 70% more likely to have an addiction specialty care visit. These results have important implications for integrating alcohol interventions in HIV care.

ObjectiveA rise in incidence of STIs has been noted in the USA and in the District of Columbia (DC). We aim to describe changes in incident STIs among persons in care for HIV in Washington, DC as well as trends in HIV viral load among those with incident STIs.MethodsWe conducted a retrospective DC Cohort analysis (n=7810) measuring STI incidence (syphilis, gonorrhoea and chlamydia) as well as incare viral load (ICVL) and percentage with all viral loads less than the limit of detection (%

AbstractBackground:Problematic use of alcohol and other drugs (AOD) is highly prevalent among people living with the human immunodeficiency virus (PLWH), and untreated AOD use disorders have particularly detrimental effects on human immunodeficiency virus (HIV) outcomes. The Healthcare Effectiveness Data and Information Set (HEDIS) measures of treatment initiation and engagement are important benchmarks for access to AOD use disorder treatment. To inform improved patient care, we compared HEDIS measures of AOD use disorder treatment initiation and engagement and health care utilization among PLWH and patients without an HIV diagnosis. Methods:Patients with a new AOD use disorder diagnosis documented between October 1, 2014, and August 15, 2015, were identified using electronic health records (EHR) and insurance claims data from 7 health care systems in the United States. Demographic characteristics, clinical diagnoses, and health care utilization data were also obtained. AOD use disorder treatment initiation and engagement rates were calculated using HEDIS measure criteria. Factors associated with treatment initiation and engagement were examined using multivariable logistic regression models. Results:There were 469 PLWH (93% male) and 86,096 patients without an HIV diagnosis (60% male) in the study cohort. AOD use disorder treatment initiation was similar in PLWH and patients without an HIV diagnosis (10% vs. 11%, respectively). Among those who initiated treatment, few engaged in treatment in both groups (9% PLWH vs. 12% patients without an HIV diagnosis). In multivariable analysis, HIV status was not significantly associated with either AOD use disorder treatment initiation or engagement. Conclusions:AOD use disorder treatment initiation and engagement rates were low in both PLWH and patients without an HIV diagnosis. Future studies need to focus on developing strategies to efficiently integrate AOD use disorder treatment with medical care for HIV.

Research is needed to better understand relations between immunosuppression and HIV viraemia and risk for non-Hodgkin lymphoma, a common cancer in people living with HIV. We aimed to identify key CD4 count and HIV RNA (viral load) predictors of risk for non-Hodgkin lymphoma, overall and by subtype.

Adults with HIV have an increased burden of non-AIDS-defining cancers, myocardial infarction, end-stage liver disease, and end-stage renal disease. The objective of this study was to estimate the population attributable fractions (PAFs) of preventable or modifiable HIV-related and traditional risk factors for non-AIDS-defining cancers, myocardial infarction, end-stage liver disease, and end-stage renal disease outcomes.

To date, there are no standardized, well-accepted, quality metrics that guide care for adults with sickle cell disease (SCD). The primary objective of this study was to evaluate the quality metrics that are in use at the Adult Sickle Cell Disease Program at Johns Hopkins Hospital (JHH) and the applicability of the metrics to Kaiser Permanente Mid-Atlantic States (KPMAS), an integrated healthcare system with a developing adult sickle cell disease program.

The National Patient-Centered Clinical Research Network (PCORnet) supports observational and clinical research using health care data. The PCORnet Antibiotics and Childhood Growth Study is one of PCORnet's inaugural observational studies. We sought to describe the processes used to integrate and analyze data from children across 35 participating institutions, the cohort characteristics, and prevalence of antibiotic use.

Hepatitis C virus infection remains a significant global health problem. Many individuals are unaware of their infection or disease stage. Innovations in care that promote rapid and easy identification of at-risk populations for screening, comprehensive diagnostic screening, and triage to curative direct-acting antiviral medications will accelerate efforts to eradicate hepatitis C.

HIV testing and incidence are stable, but trends for certain populations are concerning. Primary prevention must be reinvigorated and target vulnerable populations. Science and policy have progressed to improve the accuracy, speed, privacy, and affordability of HIV testing. More potent and much better tolerated HIV treatments and a multidisciplinary approach to care have increased adherence and viral suppression. Changes to health care law in the United States seek to expand the affordability and access of improved HIV diagnostics and treatment. Continued challenges include improving long-term outcomes in people on lifetime regimens, reducing comorbidities associated with those regimens, and preventing further transmission.

To determine the association of HIV infection and immunodeficiency with incidence of ischemic stroke.

An obesity epidemic has been documented among adult Latinos/as in Latin America and the United States (US); however, little is known about obesity among Latinos/as with HIV (PWH). Moreover, Latinos/as PWH in the US may have different weight trajectories than those in Latin America due to the cultural and environmental contexts. We assessed weight and body mass index (BMI) trajectories among PWH initiating antiretroviral therapy (ART) across 5 countries in Latin America and the Caribbean and the US.

Adults aged 50 years or older comprise a majority of people with HIV in the USA. Our objective was to describe observed differences by age in CD4 count at entry into HIV care, timing of antiretroviral therapy (ART) prescription, and CD4 count at time of ART prescription before (2004–11) and during (2012–18) the current era of universal treatment.

Nelfinavir was once one of the most commonly used protease inhibitors (PIs). To investigate the genetic mechanisms of multidrug resistance in protease isolates with the primary nelfinavir resistance mutation D30N, we analyzed patterns of protease mutations in 582 viruses with D30N from 460 persons undergoing HIV-1 genotypic resistance testing at Stanford University Hospital from 1997 to 2005. Three patterns of mutational associations were identified. First, D30N was positively associated with N88D but negatively associated with N88S. Second, D30N and L90M were negatively associated except in the presence of N88D, which facilitated the cooccurrence of D30N and L90M. Third, D30N + N88D + L90M formed a stable genetic backbone for the accumulation of additional protease inhibitor (PI) resistance mutations. In 16 patients having isolates with more than one combination of mutations at positions 30, 88, and 90, all exhibited one of the steps in the following progression: D30N→D30N + N88D→D30N + N88D + L90M→D30N + N88D + L90M + (L33F ± I84V or M46I/L ± I54V). Although nelfinavir is now used less frequently than other PIs, the well-delineated mutational pathway we describe is likely to influence patterns of cross-resistance in viruses from persons who experience virologic failure while receiving this PI.

HYPOTHESIS Matched patients who test positive or negative for human immunodeficiency virus (HIV) who are undergoing comparable operations have similar complication rates and outcomes. DESIGN A retrospective study of surgical outcomes in HIV-infected and matched HIV-noninfected patients. Baseline information including HIV-related laboratory results, complications, and mortality was collected from printed and electronic records through 12 postoperative months. SETTING Kaiser Permanente Medical Care Program–Northern California, an integrated health organization with more than 3 million members, including more than 5000 HIV-infected members. PATIENTS From July 1,1997, through June 30, 2002, HIV-infected members undergoing surgical procedures were matched 1:1 with HIV-noninfected patients undergoing surgical procedures by type, location, and year of surgery as well as by sex and age. Surgical procedures studied included appendectomy, arthrotomy or arthroscopy, bowel resection, cholecystectomy, cardiothoracic procedures, hernia repair, hysterectomy, hip or knee replacement, laparoscopy or laparotomy, and mammoplasty. MAIN OUTCOME MEASURES Complications and mortality through 12 postoperative months, comparisons between HIV-infected and HIV-noninfected patients using matched-pair analyses, and HIV-infected cohort data were analyzed using the Fisher exact test and logistic regression. RESULTS Of 332 HIV-infected–HIV-noninfected pairs (mean age, 46.7 years; male sex, 91%), more than 95.0% were followed up through 12 postoperative months or until their deaths. Pairs had similar comorbidities, length of hospital stay, and number of postoperative surgical visits (P>.05, all variables). Among HIV-infected patients, the median years with HIV infection was 8.4 years; median CD4 T-cell count was 379/μL; 61.5% of these patients had an HIV RNA level less than 500 copies per milliliter; and 68% were receiving highly active antiretroviral therapy. Various complications were no more frequent among HIV-infected than in HIV-noninfected patients (11.1% vs 10.2%; P = .79), except for pneumonia (P = .04). There were more deaths within the 12 postoperative months in HIV-infected patients (10/332 vs 2/332; P = .02); 2 patients died 30 days or less after being operated on. Among HIV-infected patients, viral load of 30 000 copies per milliliter or more was associated with increased complications (adjusted odds ratio, 2.95; P = .007), but a CD4 cell count less than 200/μL was not associated with poorer outcomes. CONCLUSIONS The HIV-infected patients had more incidences of postoperative pneumonia and higher 12-month mortality, although other operative outcomes were comparable for HIV-infected and HIV-noninfected patients. Viral suppression to fewer than 30 000 copies per milliliter reduced surgical complications.arch surg. 2006;141():1238-1245--

Background:Clinicopathological characteristics and prognosis for patients with HIV (PWH) and T-cell lymphomas (TCLs) in the current antiretroviral therapy (ART) era remains unknown. The primary objective of this study was to determine outcomes of patients with mature T and NK/T-cell lymphomas with and without HIV (PWoH) in North America. A secondary objective was to define variations in the survival of patients with TCLs and AIDS-defining B-cell lymphomas (A-BCLs) in the presence of ART.
