IMPORTANCEAs self-collected home antigen tests become widely available, a better understanding of their performance during the course of SARS-CoV-2 infection is needed. OBJECTIVE To evaluate the diagnostic performance of home antigen tests compared with reverse transcription-polymerase chain reaction (RT-PCR) and viral culture by days from illness onset, as well as user acceptability. DESIGN, SETTING, AND PARTICIPANTS This prospective cohort study was conducted from January to May 2021 in San Diego County, California, and metropolitan Denver, Colorado. The convenience sample included adults and children with RT-PCR-confirmed infection who used self-collected home antigen tests for 15 days and underwent at least 1 nasopharyngeal swab for RT-PCR, viral culture, and sequencing. EXPOSURES SARS-CoV-2 infection. MAIN OUTCOMES AND MEASURES The primary outcome was the daily sensitivity of home antigen tests to detect RT-PCR-confirmed cases. Secondary outcomes included the daily percentage of antigen test, RT-PCR, and viral culture results that were positive, and antigen test sensitivity compared with same-day RT-PCR and cultures. Antigen test use errors and acceptability were assessed for a subset of participants. RESULTS This study enrolled 225 persons with RT-PCR-confirmed infection (median [range] age, 29 [1-83] years; 117 female participants [52%]; 10 [4%] Asian, 6 [3%] Black or African American, 50 [22%] Hispanic or Latino, 3 [1%] Native Hawaiian or Other Pacific Islander, 145[64%] White, and 11 [5%] multiracial individuals) who completed 3044 antigen tests and 642 nasopharyngeal swabs. Antigen test sensitivity was 50% (95% CI, 45%-55%) during the infectious period, 64% (95% CI, 56%-70%) compared with same-day RT-PCR, and 84% (95% CI, 75%-90%) compared with same-day cultures. Antigen test sensitivity peaked 4 days after illness onset at 77% (95% CI, 69%-83%). Antigen test sensitivity improved with a second antigen test 1 to 2 days later, particularly early in the infection. Six days after illness onset, antigen test result positivity was 61% (95% CI, 53%-68%). Almost all (216 [96%]) surveyed individuals reported that they would be more likely to get tested for SARS-CoV-2 infection if home antigen tests were available over the counter. CONCLUSIONS AND RELEVANCEThe results of this cohort study of home antigen tests suggest that sensitivity for SARS-CoV-2 was moderate compared with RT-PCR and high compared with viral culture. The results also suggest that symptomatic individuals with an initial negative home antigen test result for SARS-CoV-2 infection should test again 1 to 2 days later because test sensitivity peaked several days after illness onset and improved with repeated testing.
Women living with HIV are at increased risk for psychosocial distress, especially among social and economically disadvantaged women living in rural areas. Little is known about how social support and wealth impacts the mental health of women caring for young children in low- and middle-income countries. The purpose of this paper was to assess demographic, socio-economic, and social support correlates of depression and anxiety in HIV-infected+ female caregivers living in rural Uganda. Depression and anxiety were assessed using the Hopkins Symptom Checklist (HSCL-25), two-domains of social support (family and community) were measured with the adapted Multidimensional Scale for Perceived Social Support, and wealth was measured using a checklist of material possessions and housing quality among 288 women. Multivariable linear regression models assessed the association of depression and anxiety with demographic and social predictors. Sixty one percent of women reported clinically significant symptoms of depression or anxiety using the standard HSCL-25 cut-off of >1.75. Lower wealth (p=0.01) and family support (p=0.01) were significantly associated with more depressive symptoms, with greater family support being more protective of depression in the highest wealth group (top 20%) compared to the lowest. More anxiety symptoms were associated with lower wealth (p=0.001), lower family support (p=0.02), and higher community support (p=0.003). Economic and social support factors are important predictors of caregiver mental health in the face of HIV disease in rural Uganda. Findings suggest that interventions should consider ways to increase economic opportunities and strengthen family support for HIV+ caregivers.
Objective Early childhood development (ECD) programs typically combine healthy nutrition and cognitive stimulation in an integrated model. We separately delivered these two components in a cluster randomized controlled trial (RCT) to evaluate their comparative effectiveness in promoting healthy child development and caregiver mental health. This is the first study to do so for HIV-affected children and their infected mothers,. Methods 221 HIV-exposed but uninfected (HEU) child (2 to 3 years old) and caregiver dyads in 18 geographic clusters in Eastern Uganda were randomized by cluster to receive biweekly individualized sessions of either 1) Mediational Intervention for Sensitizing Caregivers (MISC) training emphasizing cognitive stimulation, or 2) Uganda Community Based Association for Child Welfare program that delivered (UCOBAC) health and nutrition training. Children were evaluated at baseline, six months, one year (training conclusion), and one-year post-training with the Mullen Scales of Early Learning (MSEL), the Color-Object Association Test (COAT) for memory, the Early Childhood Vigilance Test (ECVT) of attention, and the Behavior Rating Inventory of Executive Function (BRIEF-parent). The Caldwell HOME was completed by observers to gauge caregiving quality after training. Caregiver depression/anxiety (Hopkins Symptom Checklist-25) and functionality (list of activities of daily living) were also evaluated. Data collectors were blinded to trial arm assignment. Results MISC resulted in significantly better quality of caregiving compared to UCOBAC mid-intervention with an adjusted mean difference (MadjDiff ) of 2.34 (95% CI: 1.54, 3.15, p<0.01), post intervention (MadjDiff=2.43, 95% CI: 1.61, 3.25, p<0.01) and at one year follow-up (MadjDiff=2.07, 95% CI: 1.23, 2.90, p<0.01). MISC caregivers reported more problems on the BRIEF for their child at one-year post-training only (p<0.01). Caregiving quality (HOME) was significantly correlated with MSEL composite performance one-year post training for both the MISC and the UCOBAC trial arms. Likewise, physical growth was significantly related to child development outcomes even though it did not differ between trial arms. Conclusions Even though MISC demonstrated an advantage of improving caregiving quality, it did not produce better child cognitive outcomes compared to health and nutrition training.
BackgroundKabul has over 12,000 people who inject drugs (PWID), most of them heroin users, and opioid substitution therapy has recently been introduced as an effective method to reduce opioid use. We aimed to evaluate a pilot Opioid Substitution Therapy Pilot Program (OSTPP) in Kabul, Afghanistan, particularly to (1) describe characteristics of the participants enrolled in the program and (2) identify factors associated with client retention in the OSTPP.FindingsTwo cross-sectional surveys evaluated participants attending the OSTPP at baseline (n = 83) and 18 months after (n = 57). Questionnaires assessed socio-demographic, drug use behavior, and general and mental health factors. After 18 months, 57 participants remained in the OSTPP. Participants lost to follow-up were younger (p < 0.01) and married (p < 0.01) and had no family contact (p < 0.01). Participants at 18 months reported no criminal activity in the last month and only two (3.5 %) reported heroin use in the last month, constituting significant decreases from baseline.ConclusionsWhile preliminary results are promising, further evaluation is needed to determine the feasibility of implementing OSTPP in this setting and effectiveness in reducing injection risk behaviors in Afghanistan.
Objective To assess the structural overlap between the Behavior Rating Inventory of Executive Function (BRIEF) and Achenbach Child Behavior Check List (CBCL) among children in Uganda. Methods Caregiver ratings for the BRIEF and CBCL were obtained for two independent samples of school-aged children: 106 children (5-12 years old, 50% males) with a history of severe malaria, and on 144 HIV-infected children (5-12 years old, 58% males) in Uganda. Exploratory factor analysis was used to evaluate the factor structure of the 8 sub-scales for the BRIEF and the 8 scales of the CBCL to determine correlation. Results Overall, children in the severe malaria group had higher (increased symptom) BRIEF and CBCL scores than children in the HIV-infected group. We identified 3 factors that provided a reasonable fit to the data and could be characterized as 3 specific domains: 1) Metacognition, which consisted of the scales in the BRIEF Metacognition domain; 2) Behavioral Adjustment, which was comprised of the scales in the BRIEF Behavioral Regulation domain and the Externalizing Symptoms scales in the CBCL; and 3) Emotional Adjustment, which mainly consisted of the Internalizing Symptoms scales in the CBCL. The BRIEF Behavior Regulation and CBCL Externalizing Symptoms scales, however, did overlap in terms of assessing similar behavior symptoms. These findings were consistent across the severe malaria and HIV-infected samples of children. Conclusion The BRIEF and CBCL instruments offer distinct, yet complementary, assessments of behavior in clinical pediatric populations in the Ugandan context, supporting the use of these measures for similar research settings.
Maternal mental health (particularly depression) may influence how they report on their child’s behavior. Few research studies have focused on Sub-Saharan countries where pediatric HIV concentrates and impacts child neuropsychological development and caregiver mental health. We investigated the associations between caregivers’ depressive symptoms and neuropsychological outcomes in HIV-infected (n=118) and HIV-exposed (n=164) Ugandan children aged 2–5 years. We compared performance-based tests of development (Mullen Scales of Early Learning, Color Object Association Test), to a caregiver report of executive function (Behavior Rating Inventory of Executive Function, BRIEF). Caregivers were assessed with Hopkins Symptom Checklist-25 depression subscale. The associations between all BRIEF indices and caregiver’s depression symptoms were differential according to child’s HIV status. Caregivers with greater depressive symptoms reported their HIV-infected children as having more behavioral problems related to executive functioning. Assessment of behavior of HIV-infected children should incorporate a variety of sources of information and screening of caregiver mental health.
