Clinical characteristics and predictors of COVID-19 in a community sample from urban areas of Chennai, Southern India.

In early 2020, with the arrival of the first case of COVID-19 in India, the laboratory at The Tamil Nadu Dr. MGR Medical University was recognized as a national testing site and received samples from two zones of Greater Chennai Corporation. This descriptive study analyzed the testing outcomes, along with demographics, self-reported symptoms, potential exposure to COVID-19 that were recorded in Sample Report Forms between June and September 2020. Nasopharygeal/oropharyngeal swabs were tested for SARS CoV-2 by RT-PCR Test. Of the 18,082 samples that were tested, 18% (3267) received a COVID-19 positive RT-PCR result for COVID-19. Among the COVID-19 positives, 40.9% (1336) were females (p < 0.000). Individuals in the age groups 21-30 and 31-40 years included the largest number (767, 23.48% each) of COVID-19 positive cases. The largest number of cases were from those who were classified as Severe Acute Respiratory Illness (SARI) or Influenza Like Illness (ILI) (1657, 50.7%) followed by those who reported direct contact with a COVID-19 lab confirmed case (1163, 35.6%). Among those with symptoms, 1791 (28.9%) tested COVID-19 positive compared to 1476 who were COVID-19 positive and asymptomatic (p < 0.001). Main symptoms were cough (32.1%), fever (48.3%), body ache (21.04%) and sore throat (30.60%). In multivariable analysis, history of SARI/ILI, contact with a confirmed case and having fever, cough and sore throat were the main predictors of being COVID-19 positive. Therefore, clinical and demographic characteristics correlated with COVID-19 positivity. And classification of patients based on self-reported symptoms and risk categories offers a model to prioritize testing and vaccination efforts.

Brief Report: HIV Is Associated With Impaired Pulmonary Diffusing Capacity Independent of Emphysema.

BACKGROUND: HIV is associated with accelerated decline in lung function and increased risk for chronic obstructive pulmonary disease (COPD). Recently, there has been growing attention toward the impairment in the diffusing capacity of the lungs for carbon monoxide (DLCO), a marker of pulmonary gas exchange, observed among persons living with HIV. Although increased emphysema can contribute to the DLCO impairment observed, other factors may drive this association. METHODS: Using cross-sectional data from the Study of HIV in the Etiology of Lung Disease, we studied the association between HIV and DLCO independent of emphysema. We also analyzed the joint influence of HIV and COPD on DLCO impairment. An analysis was conducted among 339 participants (229 with HIV) with lung function and chest CT imaging data. Multivariable regression models were generated with percent predicted DLCO and odds of DLCO impairment as outcomes. RESULTS: After adjusting for confounders, including emphysema severity, HIV was associated with lower DLCO (ß -4.02%; P = 0.020) and higher odds of DLCO impairment (odds ratio 1.93; P = 0.017). Even among those without COPD, HIV was independently associated with lower DLCO (ß -3.89%; P = 0.049). Compared with HIV-uninfected participants without COPD, those with both HIV and COPD experienced the greatest impairment in DLCO (ß -14.81; P < 0.001). CONCLUSIONS: HIV is associated with impaired pulmonary gas exchange independent of emphysema severity. Our data also suggest a potentially additive influence between HIV and COPD on DLCO impairment. Further studies should investigate the other factors, including pulmonary vascular disease, which may contribute to DLCO impairment among persons living with HIV.

Association of Lung Function With HIV-Related Quality of Life and Health Care Utilization in a High-Risk Cohort.

BACKGROUND: Chronic respiratory disease represents an important comorbidity for persons living with HIV (PLWH). HIV itself is associated with greater impairment in lung function. We aimed to determine the association between declining lung function and both quality of life (QOL) and health care utilization for PLWH. METHODS: Using longitudinal data from the Study of HIV Infection in the Etiology of Lung Disease 2009-2017, we studied the association between changes in lung function and both QOL and acute care events (emergency department visit or hospitalization). The Medical Outcomes Studies-HIV Questionnaire provided QOL domains. Multivariable regression models were performed with generalized estimating equations accounting for 1499 participants, 485 with HIV, contributing 10,825 spirometry visits. RESULTS: Among PLWH, decreased FEV1 was associated with worse physical health for those with higher viral load [ß: -1.66, 95% confidence interval (CI): -3.11 to -0.39] compared to those with viral suppression (ß: -0.58, 95% CI: -1.06 to -0.162), even in those without airflow obstruction. Lower FEV1 was also associated with increased odds of both emergency department (odds ratio: 1.21, 95% CI: 1.09 to 1.34) and inpatient (odds ratio: 1.26, 95% CI: 1.12 to 1.42) hospitalizations for PLWH. Lung function was not associated with increased odds of acute care events for HIV-uninfected participants. CONCLUSIONS: FEV1 declines represent an independent predictor of QOL and acute care events among PLWH. Although the generalizability of these results may be limited, because of the high-risk population included, findings suggest that care for PLWH should involve monitoring FEV1 over time, especially in those with poor virologic control, with emphasis on the development and implementation of interventions to mitigate lung function decline.

Hypertension Self-management in Socially Disadvantaged African Americans: the Achieving Blood Pressure Control Together (ACT) Randomized Comparative Effectiveness Trial.

BACKGROUND: Effective hypertension self-management interventions are needed for socially disadvantaged African Americans, who have poorer blood pressure (BP) control compared to others. OBJECTIVE: We studied the incremental effectiveness of contextually adapted hypertension self-management interventions among socially disadvantaged African Americans. DESIGN: Randomized comparative effectiveness trial. PARTICIPANTS: One hundred fifty-nine African Americans at an urban primary care clinic. INTERVENTIONS: Participants were randomly assigned to receive (1) a community health worker ("CHW") intervention, including the provision of a home BP monitor; (2) the CHW plus additional training in shared decision-making skills ("DoMyPART"); or (3) the CHW plus additional training in self-management problem-solving ("Problem Solving"). MAIN MEASURES: We assessed group differences in BP control (systolic BP (SBP) < 140 mm Hg and diastolic BP (DBP) < 90 mmHg), over 12 months using generalized linear mixed models. We also assessed changes in SBP and DBP and participants' BP self-monitoring frequency, clinic visit patient-centeredness (i.e., extent of patient-physician discussions focused on patient emotional and psychosocial concerns), hypertension self-management behaviors, and self-efficacy. KEY RESULTS: BP control improved in all groups from baseline (36%) to 12 months (52%) with significant declines in SBP (estimated mean [95% CI] - 9.1 [- 15.1, - 3.1], - 7.4 [- 13.4, - 1.4], and - 11.3 [- 17.2, - 5.3] mmHg) and DBP (- 4.8 [- 8.3, - 1.3], - 4.0 [- 7.5, - 0.5], and - 5.4 [- 8.8, - 1.9] mmHg) for CHW, DoMyPART, and Problem Solving, respectively). There were no group differences in BP outcomes, BP self-monitor use, or clinic visit patient-centeredness. The Problem Solving group had higher odds of high hypertension self-care behaviors (OR [95% CI] 18.7 [4.0, 87.3]) and self-efficacy scores (OR [95% CI] 4.7 [1.5, 14.9]) at 12 months compared to baseline, while other groups did not. Compared to DoMyPART, the Problem Solving group had higher odds of high hypertension self-care behaviors (OR [95% CI] 5.7 [1.3, 25.5]) at 12 months. CONCLUSION: A context-adapted CHW intervention was correlated with improvements in BP control among socially disadvantaged African Americans. However, it is not clear whether improvements were the result of this intervention. Neither the addition of shared decision-making nor problem-solving self-management training to the CHW intervention further improved BP control. TRIAL REGISTRY: ClinicalTrials.gov Identifier: NCT01902719.

Improving urban African Americans' blood pressure control through multi-level interventions in the Achieving Blood Pressure Control Together (ACT) study: a randomized clinical trial.

BACKGROUND: Given their high rates of uncontrolled blood pressure, urban African Americans comprise a particularly vulnerable subgroup of persons with hypertension. Substantial evidence has demonstrated the important role of family and community support in improving patients' management of a variety of chronic illnesses. However, studies of multi-level interventions designed specifically to improve urban African American patients' blood pressure self-management by simultaneously leveraging patient, family, and community strengths are lacking. METHODS/DESIGN: We report the protocol of the Achieving Blood Pressure Control Together (ACT) study, a randomized controlled trial designed to study the effectiveness of interventions that engage patient, family, and community-level resources to facilitate urban African American hypertensive patients' improved hypertension self-management and subsequent hypertension control. African American patients with uncontrolled hypertension receiving health care in an urban primary care clinic will be randomly assigned to receive 1) an educational intervention led by a community health worker alone, 2) the community health worker intervention plus a patient and family communication activation intervention, or 3) the community health worker intervention plus a problem-solving intervention. All participants enrolled in the study will receive and be trained to use a digital home blood pressure machine. The primary outcome of the randomized controlled trial will be patients' blood pressure control at 12months. DISCUSSION: Results from the ACT study will provide needed evidence on the effectiveness of comprehensive multi-level interventions to improve urban African American patients' hypertension control.

Recruiting Black Men Who Have Sex with Men and Women (BMSMW) in an Urban Setting for HIV Prevention Research.

OBJECTIVES: Concerns related to stigma and confidentiality limit HIV-related study recruitment and retention of Black men who have sex with men and women (MSMW). This paper examines lessons learned from recruitment strategies utilized in enrolling 437 participants between 2007 and 2011 for a randomized controlled trial to test a culturally specific HIV risk-reduction intervention for Black MSMW. METHODS: Interested respondents completed a brief screener and participants completed surveys at baseline and at post, 3 and 6 months follow-up. Recruitment patterns were assessed by examining the source of study information reported when respondents were asked how they learned about the study. Chi-square tests were then conducted to examine differences in the distribution of participants by self-reported HIV status, age group and socio-economic status (SES) for each type of study information source. RESULTS: Regardless of HIV or SES, study respondents were more likely to have received information about the study through a service agency than from other sources. Participants ages 30-49 and 50+ years were most likely to have learned about the study from an agency (34.9% and 27.0%, respectively) or another participant/friend (20.1%, 23.1%) and least likely to have found out from bus (0.8%, 0.0%) or radio (1.3%, 0.0%) advertisements; whereas younger participants were more likely to have heard about the study through a friend/participant (23.4%) than an agency (15.4%). Although, 14.1% of participants' ages less than 30 years reported the Internet as their source of study information, this compared to just 2.7% and 4.8% for participants in the 30-49 and 50-plus age groups. CONCLUSIONS: While agencies and referrals from personal networks appear to be the most significant recruitment source for potential HIV research participants, there is evidence that Internet based tools may enhance recruitment, particularly among younger Black MSMW.

Efficacy of a culturally congruent HIV risk-reduction intervention for behaviorally bisexual black men: results of a randomized trial.

OBJECTIVES: Black men who have sex with men and women (MSMW) experience high HIV rates and may not respond to interventions targeting gay-identified men. We tested the efficacy of the Men of African American Legacy Empowering Self (MAALES), a multisession, small-group holistically framed intervention designed to build skills, address sociocultural issues, and reduce risk behaviors in black MSMW. DESIGN: From 2007 to 2011, we enrolled 437 black MSMW into a parallel randomized controlled trial that compared MAALES to the control condition, a single, individualized HIV risk-reduction session. METHODS: Participants completed surveys at baseline, 3 months, and 6 months postintervention. We used multiple regressions to compare risk behaviors at follow-up between the intervention and control groups while adjusting for baseline risk behaviors, time between assessments, other covariates, and clustering. We used inverse probability weighting (IPW) to adjust for loss-to-follow-up while carrying out these regressions with the 291 (76.4%) randomized participants who completed at least one follow-up. RESULTS: Participants were largely low-income (55% reported monthly incomes <$1000); nearly half had previously tested HIV positive. At 6 months of follow-up, unadjusted within-group analyses demonstrated reduced risk behaviors for the MAALES but not the control group. Adjusted results indicated significant intervention-associated reductions in the numbers of total anal or vaginal sex acts [risk ratio = 0.61; 95% confidence interval (CI) 0.49­0.76], unprotected sex acts with women (risk ratio = 0.50; 95% CI 0.37­0.66), and female partners (risk ratio = 0.56; 95% CI 0.44­0.72). Near significant reductions were observed for number of male intercourse partners. CONCLUSION: The MAALES intervention was efficacious at reducing HIV risk behaviors in black MSMW.

Facilitators and barriers to hypertension self-management in urban African Americans: perspectives of patients and family members.

INTRODUCTION: We aimed to inform the design of behavioral interventions by identifying patients' and their family members' perceived facilitators and barriers to hypertension self-management. MATERIALS AND METHODS: We conducted focus groups of African American patients with hypertension and their family members to elicit their views about factors influencing patients' hypertension self-management. We recruited African American patients with hypertension (n = 18) and their family members (n = 12) from an urban, community-based clinical practice in Baltimore, Maryland. We conducted four separate 90-minute focus groups among patients with controlled (one group) and uncontrolled (one group) hypertension, as well as their family members (two groups). Trained moderators used open-ended questions to assess participants' perceptions regarding patient, family, clinic, and community-level factors influencing patients' effective hypertension self-management. RESULTS: Patient participants identified several facilitators (including family members' support and positive relationships with doctors) and barriers (including competing health priorities, lack of knowledge about hypertension, and poor access to community resources) that influence their hypertension self-management. Family members also identified several facilitators (including their participation in patients' doctor's visits and discussions with patients' doctors outside of visits) and barriers (including their own limited health knowledge and patients' lack of motivation to sustain hypertension self-management behaviors) that affect their efforts to support patients' hypertension self-management. CONCLUSION: African American patients with hypertension and their family members reported numerous patient, family, clinic, and community-level facilitators and barriers to patients' hypertension self-management. Patients' and their family members' views may help guide efforts to tailor behavioral interventions designed to improve hypertension self-management behaviors and hypertension control in minority populations.

Learning from successful interventions: A culturally congruent HIV risk-reduction intervention for African American men who have sex with men and women.

Few HIV prevention interventions have been developed for African American men who have sex with men or who have sex with both men and women. Many interventions neglect the historical, structural or institutional, and sociocultural factors that hinder or support risk reduction in this high-risk group. We examined ways to incorporate these factors into Men of African American Legacy Empowering Self, a culturally congruent HIV intervention targeting African American men who have sex with men and women. We also studied how to apply key elements from successful interventions to future efforts. These elements include having gender specificity, a target population, a theoretical foundation, cultural and historical congruence, skill-building components, and well-defined goals.

Sexual behavior, sexual identity, and substance abuse among low-income bisexual and non-gay-identifying African American men who have sex with men.

We examined the role of drug use and addiction in same-sex sexuality among non-gay-identifying African American men who have sex with men or with both men and women (MSM/MSMW). Between July 2005 and February 2006, we conducted seven focus groups with 46 predominately low socioeconomic status African American MSM/MSMW. A total of 29 men self-identified as HIV-infected and 17 self-identified as uninfected. Focus group transcripts were analyzed using consensual qualitative research techniques. Alcohol, crack cocaine, and crystal methamphetamine were the primary drugs mentioned by participants. Drug use was identified as playing a central role in same-sex sexuality for many African American MSM/MSMW. Participants described alcohol use and drug transactions, use, and addiction as motivating sex with men, allowing and rationalizing same-sex activity and unprotected sex, and facilitating access to male sex partners. Some of those in treatment for substance abuse indicated that a readiness to admit their same-sex activity and come to terms with their homosexuality/bisexuality was necessary for recovery. Because successful engagement of non-gay-identifying African American MSM/MSMW is essential to the reduction of HIV transmission and substance abuse in Black communities, findings call for drug treatment approaches that acknowledge and accept diverse sexuality in clients. Service providers and policy-makers may be guided by these findings toward building cultural competency among direct service staff. Future research should examine interrelated dynamics of sexual activity, identity, and drug use as they evolve within individual African American MSM/MSMW and compare the frequency with which sex, condom use, and substance use co-occur with male versus female partners.
