Programmatic Implications of National Recent HIV Infection Surveillance in Cambodia.

We compared characteristics of HIV diagnosis and recent HIV infection (ie, likely acquired within the last year) in Cambodia. We included individuals ≥ 15 years old accessing HIV testing. From August 2020 to August 2022, 53 031 people were tested for HIV, 6868 were newly diagnosed, and 192 were recently infected. We found differences in geographical burden and risk behaviors with diagnosis and recency (eg, men who have sex with men, transgender women, and entertainment workers had a nearly 2-fold increased odds of testing positive for recent infection compared to being diagnosed with HIV). Recent infection surveillance may provide unique insights into ongoing HIV acquisition to inform programs.

Clinical sequelae among individuals with pauci-symptomatic or asymptomatic Ebola virus infection and unrecognised Ebola virus disease in Liberia: a longitudinal cohort study.

BACKGROUND: Whether or not individuals with pauci-symptomatic or asymptomatic Ebola virus infection and unrecognised Ebola virus disease develop clinical sequelae is unknown. We assessed current symptoms and physical examination findings among individuals with pauci-symptomatic or asymptomatic infection and unrecognised Ebola virus disease compared with Ebola virus disease survivors and uninfected contacts. METHODS: Between June 17, 2015, and June 30, 2017, we studied a cohort of Ebola virus disease survivors and their contacts in Liberia. Surveys, current symptoms and physical examination findings, and serology were used to characterise disease status of reported Ebola virus disease, unrecognised Ebola virus disease, pauci-symptomatic or asymptomatic Ebola virus infection, or no infection. We pre-specified findings known to be differentially prevalent among Ebola virus disease survivors versus their contacts (urinary frequency, headache, fatigue, muscle pain, memory loss, joint pain, neurological findings, chest findings, muscle findings, joint findings, abdominal findings, and uveitis). We estimated the prevalence and incidence of selected clinical findings by disease status. FINDINGS: Our analytical cohort included 991 reported Ebola virus disease survivors and 2688 close contacts. The median time from acute Ebola virus disease onset to baseline was 317 days (IQR 271-366). Of 222 seropositive contacts, 115 had pauci-symptomatic or asymptomatic Ebola virus infection and 107 had unrecognised Ebola virus disease. At baseline, prevalent findings of joint pain, memory loss, muscle pain, and fatigue were lowest among those with pauci-symptomatic or asymptomatic infection or no infection, higher among contacts with unrecognised Ebola virus disease, and highest in reported survivors of Ebola virus disease. Joint pain was the most prevalent finding, and was reported in 434 (18%) of 2466 individuals with no infection, 14 (12%) of 115 with pauci-symptomatic or asymptomatic infection, 31 (29%) of 107 with unrecognised Ebola virus disease, and 476 (48%) of 991 with reported Ebola virus disease. In adjusted analyses, this pattern remained for joint pain and memory loss. Survivors had an increased odds of joint pain compared with unrecognised Ebola virus disease contacts (adjusted odds ratio [OR] 2·13, 95% CI 1·34-3·39); unrecognised Ebola virus disease contacts had an increased odds of joint pain compared with those with pauci-symptomatic or asymptomatic infection and uninfected contacts (adjusted OR 1·89, 95% CI 1·21-2·97). The adjusted odds of memory loss was more than four-times higher among survivors than among unrecognised Ebola virus disease contacts (adjusted OR 4·47, 95% CI 2·41-8·30) and two-times higher among unrecognised Ebola virus disease contacts than in those with pauci-symptomatic or asymptomatic infection and uninfected contacts (adjusted OR 2·05, 95% CI 1·10-3·84). By 12 months, prevalent findings had decreased in the three infected groups. INTERPRETATION: Our findings provide evidence of post-Ebola virus disease clinical sequelae among contacts with unrecognised Ebola virus disease but not in people with pauci-symptomatic or asymptomatic Ebola virus infection.

Immunogenicity of rVSVΔG-ZEBOV-GP Ebola vaccination in exposed and potentially exposed persons in the Democratic Republic of the Congo.

Despite more than 300,000 rVSVΔG-ZEBOV-glycoprotein (GP) vaccine doses having been administered during Ebola virus disease (EVD) outbreaks in the Democratic Republic of the Congo (DRC) between 2018 and 2020, seroepidemiologic studies of vaccinated Congolese populations are lacking. This study examines the antibody response at 21 d and 6 mo postvaccination after single-dose rVSVΔG-ZEBOV-GP vaccination among EVD-exposed and potentially exposed populations in the DRC. We conducted a longitudinal cohort study of 608 rVSVΔG-ZEBOV-GP-vaccinated individuals during an EVD outbreak in North Kivu Province, DRC. Participants provided questionnaires and blood samples at three study visits (day 0, visit 1; day 21, visit 2; and month 6, visit 3). Anti-GP immunoglobulin G (IgG) antibody titers were measured in serum by the Filovirus Animal Nonclinical Group anti-Ebola virus GP IgG enzyme-linked immunosorbent assay. Antibody response was defined as an antibody titer that had increased fourfold from visit 1 to visit 2 and was above four times the lower limit of quantification at visit 2; antibody persistence was defined as a similar increase from visit 1 to visit 3. We then examined demographics for associations with follow-up antibody titers using generalized linear mixed models. A majority of the sample, 87.2%, had an antibody response at visit 2, and 95.6% demonstrated antibody persistence at visit 3. Being female and of young age was predictive of a higher antibody titer postvaccination. Antibody response and persistence after Ebola vaccination was robust in this cohort, confirming findings from outside of the DRC.

Safe reopening of college campuses during COVID-19: The University of California experience in Fall 2020.

BACKGROUND: Epidemics of COVID-19 in student populations at universities were a key concern for the 2020-2021 school year. The University of California (UC) System developed a set of recommendations to reduce campus infection rates. SARS-CoV-2 test results are summarized for the ten UC campuses during the Fall 2020 term. METHODS: UC mitigation efforts included protocols for the arrival of students living on-campus students, non-pharmaceutical interventions, daily symptom monitoring, symptomatic testing, asymptomatic surveillance testing, isolation and quarantine protocols, student ambassador programs for health education, campus health and safety pledges, and lowered density of on-campus student housing. We used data from UC campuses, the UC Health-California Department of Public Health Data Modeling Consortium, and the U.S. Census to estimate the proportion of each campus' student populations that tested positive for SARS-CoV-2 and compared it to the fraction individuals aged 20-29 years who tested positive in their respective counties. RESULTS: SARS-CoV-2 cases in campus populations were generally low in September and October 2020, but increased in November and especially December, and were highest in early to mid-January 2021, mirroring case trajectories in their respective counties. Many students were infected during the Thanksgiving and winter holiday recesses and were detected as cases upon returning to campus. The proportion of students who tested positive for SARS-CoV-2 during Fall 2020 ranged from 1.2% to 5.2% for students living on campus and was similar to students living off campus. For most UC campuses the proportion of students testing positive was lower than that for the 20-29-year-old population in which campuses were located. CONCLUSIONS: The layered mitigation approach used on UC campuses, informed by public health science and augmented perhaps by a more compliant population, likely minimized campus transmission and outbreaks and limited transmission to surrounding communities. University policies that include these mitigation efforts in Fall 2020 along with SARS-CoV-2 vaccination, may alleviate some local concerns about college students returning to communities and facilitate resumption of normal campus operations and in-person instruction.

Outdoor Transmission of SARS-CoV-2 and Other Respiratory Viruses: A Systematic Review.

BACKGROUND: While risk of outdoor transmission of respiratory viral infections is hypothesized to be low, there are limited data on SARS-CoV-2 transmission in outdoor compared to indoor settings. METHODS: We conducted a systematic review of peer-reviewed papers indexed in PubMed, EMBASE, and Web of Science and preprints in Europe PMC through 12 August 2020 that described cases of human transmission of SARS-CoV-2. Reports of other respiratory virus transmission were included for reference. RESULTS: Five identified studies found a low proportion of reported global SARS-CoV-2 infections occurred outdoors (<10%) and the odds of indoor transmission was very high compared to outdoors (18.7 times; 95% confidence interval, 6.0-57.9). Five studies described influenza transmission outdoors and 2 adenovirus transmission outdoors. There was high heterogeneity in study quality and individual definitions of outdoor settings, which limited our ability to draw conclusions about outdoor transmission risks. In general, factors such as duration and frequency of personal contact, lack of personal protective equipment, and occasional indoor gathering during a largely outdoor experience were associated with outdoor reports of infection. CONCLUSIONS: Existing evidence supports the wide-held belief that risk of SARS-CoV-2 transmission is lower outdoors but there are significant gaps in our understanding of specific pathways.

Behind bars: the burden of being a woman in Brazilian prisons.

BACKGROUND: Brazil has the third largest prison population in the world. In 2016, the female prison population totaled 42,000, an increase of 656% over the population recorded in the early 2000s. The objective of this study was to describe the socialeconomic and reproductive health of women in Brazilian prisons, and the specific assistance received within the prison system. METHODS: This is a first of its kind national survey conducted in 15 female prisons in eight Brazilian states between 2014 and 2015. The sample consisted of 1327 women in closed or semi-open prison regimes. Data collection used Audio Computer-Assisted Self-Interviewing (ACASI). STATA v.15. Was use in analysis. The study was submitted to the Research Ethics Committee of the Federal University of Ceará, under CEP protocol No. 1,024,053. RESULTS: The population was overwhelmingly Black or Brown, poor and little educated. When women worked previously, they had worked as domestic servants and were the sole source of income for their families. Most were mothers, with 39% having children less than 10 years old, now in the care of others. Most were in jail for drug-related crimes. Prisons were crowded, with more than 2/3rds of the inmates sharing a cell with 6 or more inmates. Services were provide, but women had not had a cervical cancer screening within the past 3 years and breast cancer screening was not conducted. CONCLUSIONS: Overall, given their backround and prison conditions they are unlikely to change the circumstances that brought them to prison in the first place.

Economic compensation interventions to increase uptake of voluntary medical male circumcision for HIV prevention: A systematic review and meta-analysis.

BACKGROUND: Economic compensation interventions may help support higher voluntary medical male circumcision (VMMC) coverage in priority sub-Saharan African countries. To inform World Health Organization guidelines, we conducted a systematic review of economic compensation interventions to increase VMMC uptake. METHODS: Economic compensation interventions were defined as providing money or in-kind compensation, reimbursement for associated costs (e.g. travel, lost wages), or lottery entry. We searched five electronic databases and four scientific conferences for studies examining the impact of such interventions on VMMC uptake, HIV testing and safer-sex/risk-reduction counseling uptake within VMMC, community expectations about compensation, and potential coercion. We screened citations, extracted data, and assessed risk of bias in duplicate. We conducted random-effects meta-analysis. We also reviewed studies examining acceptability, values/preferences, costs, and feasibility. RESULTS: Of 2484 citations identified, five randomized controlled trials (RCTs) and three non-randomized controlled trials met our eligibility criteria. Studies took place in Kenya, Malawi, South Africa, Tanzania, Uganda, Zambia, and Zimbabwe. Meta-analysis of four RCTs showed significant impact of any economic compensation on VMMC uptake (relative risk: 5.23, 95% CI: 3.13 to 8.76). RCTs of food/transport vouchers and conditional cash transfers generally showed increases in VMMC uptake, but lotteries, subsidized VMMC, and receiving a gift appeared somewhat less effective. Three non-randomized trials showed mixed impact. Six additional studies suggested economic compensation interventions were generally acceptable, valued for addressing key barriers, and motivating to men. However, some participants felt they were insufficiently motivating or necessary; one study suggested they might raise community suspicions. One study from South Africa found a program cost of US$91 per additional circumcision and US$450-$1350 per HIV infection averted. CONCLUSIONS: Economic compensation interventions, particularly transport/food vouchers, positively impacted VMMC uptake among adult men and were generally acceptable to potential clients. Carefully selected economic interventions may be a useful targeted strategy to enhance VMMC coverage.

Low bone mineral density among HIV-infected patients in Brazil.

Decrease in bone mineral density (BMD) has been a complication among people living with HIV/AIDS. To investigate the prevalence of osteopenia/osteoporosis among HIV-infected people living in São Paulo city, we studied 108 HIV-infected patients (79 men and 29 women). We extracted data from patients' medical records and BMD was measured by dual-energy X-ray absorptiometry (DXA). Median age of participants was 42 years (interquartile range [IQR] 36-48 years), and the median time since HIV diagnosis was 4.01 years (IQR 2-11 years). Patients had acquired HIV primarily by the sexual route (men who have sex with men 44%, heterosexual 49%). Median age, duration of HIV infection, duration of ART and CD4 nadir were similar for men and women. Plasma viral load was undetectable for 53 patients (49%). Median CD4 T cell count was 399 cells/µL (IQR 247 - 568). Twenty five patients (23%) had LBMD, and there was no statistically significant difference between men and women (<-1). The associated risk factors for LBMD were older age (≥ 50 years old) and smoking with a RR of 3.87 and 2.80, respectively. Thus, despite the lack of statistically significant relationship between the use of ART and LBMD or between duration of ART and LBMD, these factors should be addressed in larger studies.

Enhancing Maternal and Child Health using a Combined Mother & Child Health Booklet in Kenya.

Under Kenyan guidelines, HIV-exposed infants should be tested for HIV DNA at 6 weeks or at first clinical contact thereafter, as infants come for immunization. Following the introduction of early infant diagnoses programmes, however, many infants were not being tested and linked to care and treatment. We developed the Mother & Child Health Booklet to help relate mothers' obstetrical history to infants' healthcare providers to facilitate follow-up and timely management. The booklet contains information on the mother's pregnancy, delivery and postpartum course and her child's growth and development, immunization, nutrition and other data need to monitor the child to 5 years of age. It replaced three separate record clinical cards. In a 1 year pilot evaluation of the booklet in Nyanza province in 2007-08, the number of HIV DNA tests on infants increased by 34% from 9966 to 13 379. The booklet was subsequently distributed nationwide in 2009. Overall, the numbers of infants tested for HIV DNA rose from 27 000 in 2007 to 60 000 in 2012, which represents approximately 60% of the estimated HIV-exposed infants in Kenya. We believe that the booklet is an important strategy for identifying and treating infected infants and, thus, in progress toward Millennium Development Goal 4.

Treatment of Kaposi sarcoma in children with HIV-1 infection.

BACKGROUND: Kaposi sarcoma (KS) remains the second most frequently diagnosed HIV-related malignancy (HRM) worldwide and most common HRM in sub-Saharan Africa where HIV is most prevalent and human herpesvirus 8 (HHV-8), the precipitating agent for the development of KS, is endemic. The majority of KS patients would likely benefit from systemic chemotherapy in addition to the initiation of antiretroviral therapy (ART). However, as paediatric staging and treatment criteria are not readily available, there are no uniform treatment criteria. OBJECTIVES: To describe the efficacy and effectiveness of current treatment options for HIV-associated KS in ART-treated paediatric populations. SEARCH METHODS: We used standard Cochrane methods to search electronic databases and conference proceedings with relevant search terms without limits to language. SELECTION CRITERIA: Randomised controlled trials, cohort studies, and case-control studies of HIV-infected infants and children <18 years old treated with ART and diagnosed with KS. DATA COLLECTION AND ANALYSIS: Abstracts of all studies identified by electronic or bibliographic scanning were examined independently by two authors. We initially identified 920 references and examined 15 in detail for study eligibility. Data were abstracted independently using a standardised abstraction form. MAIN RESULTS: After initially screening 920 titles, 15 full-text articles were closely examined by two authors. We identified four cohort studies that met our inclusion criteria for data extraction, coding, and potential meta-analysis.Using the Newcastle-Ottawa Scale and Cochrane risk of bias assessments, all observational studies had cohorts that were representative of average (treated and untreated) HIV-infected children with Kaposi sarcoma. For all outcomes of interest, no study adjusted for any other potential confounders. Two of four observational studies either explicitly described complete follow up of the study participants and/or described the characteristics of the participants lost to follow up.The use of ART together with a chemotherapeutic regimen versus ART alone appears to increase the likelihood of KS remission in HIV-infected children diagnosed with KS, although data are sparse and not adequately adjusted for staging of disease and comorbidities. Additionally, though data are sparse, the use of ART together with a chemotherapeutic regimen versus chemotherapy alone in some analyses appears to increase the likelihood of KS remission and reduce the risk of death in HIV-infected children diagnosed with KS.In this analysis, we found that the quality of evidence was very low due to small sample sizes and a paucity of paediatric literature. AUTHORS' CONCLUSIONS: Data describing the efficacy of different treatment options for pediatric KS, to include chemotherapy and ART, are sparse. However, the use of ART together with a chemotherapy regimen may be superior to the use of ART alone or of chemotherapy alone.

Ultrasound measurements of carotid intima-media thickness and plaque in HIV-infected patients on the Mediterranean diet.

AIM: To evaluate the influence of food habits, specifically adherence to the Mediterranean diet, on carotid intima-media thickness (CIMT) and the presence of plaques in HIV-infected patients taking antiretroviral therapy (ART) and non-HIV-infected participants and to determine if HIV infection contributes independently to subclinical atherosclerosis. METHODS: We conducted a cross-sectional study of 110 HIV-infected patients on ART and 131 non-HIV-infected participants at the University Hospital for Infectious Diseases in Zagreb, Croatia, from 2009-2011. CIMT measurement and determination of carotid plaque presence was detected by ultrasound. Adherence to the Mediterranean diet was assessed by a 14-point food-item questionnaire. Subclinical atherosclerosis was defined by CIMT≥0.9 mm or ≥1 carotid plaque. RESULTS: In HIV-infected patients, subclinical atherosclerosis was associated with older age (Plt;0.001; Mann-Whitney test), higher body mass index (P=0.051; Mann-Whitney test), hypertension (Plt;0.001; χ(2) test), and a lower Mediterranean diet score (P=0.035; Mann-Whitney test), and in non-HIV-infected participants with older age (P lt; 0.001; Mann-Whitney test) and hypertension (P=0.006; χ(2) test). Multivariate analysis showed that decreased adherence to the Mediterranean diet was associated with higher odds of subclinical atherosclerosis (odds ratio [OR] 2.28, 95% confidence interval [CI] 1.10-4.72, P=0.027) as was current smoking (OR 2.86, 95% CI 1.28-6.40), hypertension (OR 3.04, 95% CI 1.41-6.57), and male sex (OR 2.35, 95% CI 0.97-5.70). There was a significant interaction of age and HIV status, suggesting that older HIV-infected patients had higher odds of subclinical atherosclerosis than controls (OR 3.28, 95% CI 1.24-8.71, P=0.017 at the age of 60 years). CONCLUSION: We confirmed the association between lower adherence to the Mediterranean diet and increased risk of subclinical atherosclerosis and found that treated HIV infection was a risk factor for subclinical atherosclerosis in older individuals.

Prevalence of sexually transmitted infections among HIV-infected women in Brazil.

This study aimed to evaluate the prevalence of sexually transmitted infections (STIs) and associated risk factors in HIV-infected pregnant women followed for prenatal care in Salvador, Bahia. This was a cross-sectional study of 63 women seeking prenatal care at a reference center. Participants were interviewed regarding socio-epidemiological and clinical history, and were tested for HBsAg, anti-HCV, anti HTLV I/II, VDRL, Chlamydia trachomatis, Neisseria gonorrhoeae, Mycoplasma hominis, Ureaplasma urealyticum, CD4 count, and HIV plasma viral load. The main outcome variable was the presence of any STI. The mean age of patients was 28.2 years (16-40 years). 23 (36.5%) were diagnosed with at least one STI. The frequency of diagnoses was: HBV, 3.2%; HCV, 8.1%; HTLV I/II, 3.4%; syphilis, 9.5%; Chlamydia trachomatis, 11.1%; HPV, 15.0%; Mycoplasma hominis, 2.1%, and Ureaplasma urealyticum, 2.1%. No case of Neisseria gonorrhoeae was identified. No association was found between socio-epidemiological variables and the presence of an STI. CD4 T lymphocyte < 500 cells/µL (p=0.047) and plasma viral load >1,000 copies (p = 0.027) were associated with the presence of STI. STIs are frequent in pregnant women infected with HIV, and all HIV-infected pregnant women should be screened to decrease transmission of these pathogens and to protect their own health.

Human herpesvirus 8 infection in children and adults in a population-based study in rural Uganda.

BACKGROUND: Human herpesvirus 8 (HHV-8) infection is endemic in sub-Saharan Africa. We examined sociodemographic, behavioral, and biological factors associated with HHV-8 infection in children and adults to determine HHV-8 seroprevalence and potential routes of transmission. METHODS: Participants were 1383 children and 1477 adults from a population-based sample in a rural community in Uganda. Serum samples were tested for HHV-8 antibodies with use of an enzyme immunoassay against K8.1. RESULTS: HHV-8 seroprevalence increased from 16% among children aged 1.5-2 years to 32% among children aged 10-13 years (P <.001) and from 37% among participants aged 14-19 years to 49% among adults aged ≥ 50 years (P <.05). HHV-8 seropositivity in children was independently associated with residing with a seropositive parent (P < .001) and residing with ≥ 1 other seropositive child aged <14 years (P < .001). History of sharing food and/or sauce plates was marginally associated with HHV-8 infection in children (P = .05). Among 1404 participants aged ≥ 15 years , there was no association between correlates of sexual behavior (eg, number of lifetime sex partners and HIV infection) and HHV-8 seropositivity (P > .10). CONCLUSIONS: Our data suggest that HHV-8 is acquired primarily through horizontal transmission in childhood from intrafamilial contacts and that transmission continues into adulthood potentially through nonsexual routes.

Distant sequelae of traumatic brain injury: premature mortality and intracranial neoplasms.

OBJECTIVE: Determine the relationship between traumatic brain injury (TBI) and premature mortality and intracranial neoplasms occurring 6 months or more after TBI. PARTICIPANTS: Not applicable. DESIGN: Systematic review of the published, peer-reviewed literature. PRIMARY MEASURES: Not applicable. RESULTS: We identified 23 studies that examined premature mortality following TBI and 16 that addressed intracranial neoplasms. There was clear evidence of an association between penetrating brain injury and premature mortality among patients surviving at least 6 months; and similarly compelling evidence of an association between moderate or severe TBI and premature mortality among patients injured severely enough to require acute rehabilitation. There was inadequate evidence to reach a conclusion about whether other closed head injuries were associated with premature mortality. For intracranial neoplasms, there was an apparent association between TBI and intracranial neoplasms diagnosed within 1 year following TBI; however, these tumors were likely incidentally found during evaluation for the TBI. For tumors diagnosed more than 1 year post injury, the evidence was inadequate to conclude that there was an association, although at least 1 very large registry-based study found a borderline association. CONCLUSION: More severe TBI (ie, penetrating and moderate and severe TBI requiring rehabilitation) is associated with premature mortality among patients surviving at least 6 months. There is no clear evidence for an association between TBI and intracranial neoplasms presenting more than 1 year following TBI.

Adherence to the Mediterranean diet is associated with a lower risk of body-shape changes in Croatian patients treated with combination antiretroviral therapy.

Lipoatrophy and lipohypertrophy have been observed during long-term combination antiretroviral therapy (CART). We investigated whether consumption of a Mediterranean diet is associated with lower risk of body-shape changes in Croatian patients treated with CART. Between May 2004 and June 2005, we conducted a cross-sectional study of 136 adults with HIV-1 infection who were treated with CART for at least 1 year. Lipoatrophy and lipohypertrophy were assessed by self-report and physical examination. Adherence to a Mediterranean diet was determined by a 150-item questionnaire; a 0-9 point diet scale was created that stratified respondents as having low adherence (<4 points) and moderate to high adherence (> or =4 points). Lipoatrophy was present in 41% and lipohypertrophy in 32% of participants. Non-smokers with a dietary score > or =4 had the lowest risk for lipoatrophy. Stavudine use, female gender, and duration of CART were also independently associated with a higher risk of lipoatrophy. A dietary score of > or =4 was associated with lower risk of lipohypertrophy (adjusted OR 0.3, 95% CI 0.1-0.7; P = 0.012). Female gender, longer duration of CART, and longer known duration of HIV infection prior to CART were also independently associated with higher risk of lipohypertrophy. In conclusion, Croatians who did not smoke and moderately or highly adhered to the Mediterranean diet were least likely to have the clinical syndrome of lipoatrophy. Moderate to high adherence to a Mediterranean diet was associated with a lower risk of lipohypertrophy.
