Long‐term cultivation drives soil carbon, nitrogen, and bacterial community changes in the black soil region of northeastern China
The deteriorating soil carbon, nutrients, and microbial habitat pose a serious threat to crop production. However, the effects of long‐term cultivation with soil erosion on soil carbon, nitrogen, and bacterial communities remain poorly understood. Consequently, this study aims to explore the changes in these soil indicators in the last 110 years and their responses to soil erosion. Luvic Phaeozems in hillslope and Haplic Phaeozems in flat were sa…
Predictors of seropositivity to Sars-CoV-2 among employees at a large urban medical center
Among workers in a large urban medical center, SARS-CoV-2 seropositivity was associated with work-related COVID-19 close contacts and low mask use outside of work, suggesting that non-workplace close contacts are also relevant routes of COVID-19 spread among healthcare workers

Adherence to Antiretrovirals and HIV Viral Suppression Under Covid-19 Pandemic Interruption – Findings from a Randomized Clinical Trial Using Ingestible Sensors to Monitor Adherence
The COVID-19 pandemic had a significant impact on vulnerable populations, including people living with HIV. California implemented a coronavirus lockdown (stay-at-home order) in March 2020, which ended in January 2021. We evaluated the pandemic's impact on both clinical outcomes of HIV RNA viral load (VL) and retention rate in a randomized clinical trial conducted from May 2018 to October 2020. The intervention group took co-encapsulated antiretr…

Random forest machine learning algorithm predicts virologic outcomes among HIV infected adults in Lausanne, Switzerland using electronically monitored combined antiretroviral treatment adherence
Machine Learning (ML) can improve the analysis of complex and interrelated factors that place adherent people at risk of viral rebound. Our aim was to build ML model to predict RNA viral rebound from medication adherence and clinical data. Patients were followed up at the Swiss interprofessional medication adherence program (IMAP). Sociodemographic and clinical variables were retrieved from the Swiss HIV Cohort Study (SHCS). Daily electronic medi…
Effectiveness of an HIV-risk reduction intervention to reduce HIV transmission among serodiscordant couples in Durban, South Africa. A randomized controlled trial
Lack of condom use by married or cohabiting couples in populations with high rates of HIV infection has become a significant public health issue. This study investigated whether an HIV risk-reduction intervention (RRI) would increase condom use when delivered to serodiscordant couples as a unit. Of the 62 couples that were screened, 30 serodiscordant couples were enrolled in the study, and randomized 2:1 to an immediate intervention-waitlist cont…
Racial/ethnic discrimination
500). Factor analyses revealed 4 dimensions: Social Rejection, Stereotyping, Direct Threats/Attacks, and Police Mistreatment. In multivariate analyses, full regression models were significantly related to PTS and depression symptoms. Among the individual predictors, Social Rejection and ethnicity (Latinx) uniquely contributed to PTS symptoms in men, whereas Stereotyping and Direct Threat/Attack were associated with PTS symptoms for women. In rega…
A hybrid effectiveness/implementation trial of an evidence-based intervention for HIV-serodiscordant African American couples
Couples-based behavioral HIV prevention interventions have demonstrated efficacy, but few are routinely available in community-based settings in the United States. The Eban intervention, designed for heterosexual African American serodiscordant couples and proven efficacious in a cluster randomized trial, was implemented in community-based HIV service organizations in two cities disproportionately affected by the HIV epidemic. This article report…

A Sexual Risk and Stress Reduction Intervention Designed for HIV-Positive Bisexual African American Men With Childhood Sexual Abuse Histories
Objectives. HIV transmission risk is high among men who have sex with men and women (MSMW), and it is further heightened by a history of childhood sexual abuse (CSA) and current traumatic stress or depression. Yet, traumatic stress is rarely addressed in HIV interventions. We tested a stress-focused sexual risk reduction intervention for African American MSMW with CSA histories. Methods. This randomized controlled trial compared a stress-focused …

Sex Drugs, Peer Connections, and HIV
African American and Latino young men who have sex with men are at high risk for HIV infection. We administered brief intercept surveys (N=416) at 18 Black and Latino gay pride events in Los Angeles and New York in 2006 and 2007. Ordinal logistic regressions were used to model the effects of substance use during sex, peer connectedness, relationship status, and homelessness on condom use. Alcohol use, crystal use, homelessness, and having a prima…

Intimate Partner Violence and Maternal Depression During the Perinatal Period
This study assessed the course of perinatal depression among 210 Latinas who were and were not affected by intimate partner violence (IPV) and identified associated psychosocial factors. Peak depression prevalence occurred prenatally among 45.7% of IPV-exposed and 24.6% of non-IPV-exposed Latinas. At each assessment, depression was significantly higher for IPV-exposed compared to non-IPV-exposed mothers. Mastery and social support were associated…

A Comparison Study of Multiple Measures of Adherence to HIV Protease Inhibitors
BACKGROUND: Poor adherence to HIV protease inhibitors may compromise the effectiveness of treatment. Few studies have compared methods for measuring adherence or have related adherence measures to a clinical outcome. OBJECTIVE: To examine the relationship among a composite score of adherence, the three primary measures of adherence, and HIV virologic response. DESIGN: Longitudinal cohort study. SETTING: Public HIV clinic. PATIENTS: 108 HIV-infect…

A Longitudinal Analysis of Unmet Need for Oral Treatment in a National Sample of Medical HIV Patients
This longitudinal study examines perceived unmet dental need in a nationally representative probability sample of HIV-infected persons in medical care. A logistic regression analysis modeled the relationship between unmet need and explanatory variables. We estimate that 40% of HIV/AIDS patients report an unmet need associated with being male, being unemployed, injecting drugs, being heterosexual, lacking dental insurance, and having less educatio…

What is the Concordance Between the Medical Record and Patient Self-Report as Data Sources for Ambulatory Care
BACKGROUND: The validity of quality of care assessments relies upon data quality, yet little is known about the relative completeness and validity of data sources for evaluating the quality of care. OBJECTIVES: We evaluated concordance between ambulatory medical record and patient survey data. Levels of concordance, variations by type of item, sources of disagreement between data sources, and implications for quality of care assessment efforts ar…
Psychometric Evaluation and Calibration of Health-Related Quality of Life Item Banks
BACKGROUND: The construction and evaluation of item banks to measure unidimensional constructs of health-related quality of life (HRQOL) is a fundamental objective of the Patient-Reported Outcomes Measurement Information System (PROMIS) project.

The PROMIS Steering Committee selected 5 HRQOL domains for initial f…
Item Response Theory Analyses of Physical Functioning Items in the Medical Outcomes Study
BACKGROUND: Constructing and evaluating item pools that measure a single domain of health-related quality of life (HRQOL) is one of the fundamental objectives of the Patient Reported Outcome Measurement and Information System (PROMIS) project. The initial focus of PROMIS is on 5 HRQOL domains: physical function, fatigue, pain, emotional distress, and social/role participation. Analysis of related, available data can inform construction of these n…
