Human Metapneumovirus-Associated Hospitalization in HIV-1 Exposed Uninfected and HIV-1 Uninfected Children Less Than 5 Years in South Africa.

Using hospital surveillance data, we estimated Human metapneumovirus (hMPV) hospitalization incidence by age and HIV-exposure status. hMPV-associated hospitalization incidence was highest in <1-year children. Incidence rate ratios of HIV-exposed over unexposed children were 1.5 (95%CI 0.9-2.4) for <6-month children, 1.4 (95%CI 0.7-2.4) for 6- to 11-month children and 0.9 (95%CI 0.4-1.9) for 12- to 59-month children.

Fetal Transfer of Human Metapneumovirus-Neutralizing Antibodies Is Reduced From Mothers Living With HIV-1.

Transplacental hMPV-neutralizing antibody transfer was reduced from mothers living with HIV-1. However, a comparison of antibody titers at birth between hMPV hospitalization cases at <6 months and matched controls suggested that reduced maternal antibody might not be the primary cause of the previously reported elevated hMPV risk in HIV-1-exposed infants.

Epidemiology of Human Metapneumovirus-associated Lower Respiratory Tract Infections in African Children: Systematic Review and Meta-analysis.

BACKGROUND: Human metapneumovirus (hMPV) has been associated with upper and lower respiratory tract infections (LRTI) in children and adults. This systematic review evaluated the epidemiology of hMPV-associated LRTI, including severe acute respiratory infection (SARI) hospitalization or clinically diagnosed severe pneumonia, in African children under 5 years of age. METHODS: We searched Science Direct, PubMed, Cochrane Central, Scopus, and WHO regional databases using the terms "("Human metapneumovirus" AND "Africa") OR ("hMPV" AND "Africa")" up to September 17, 2020. Other sources included ClinicalTrials.gov to obtain unpublished data. Studies were included if children were less than 5 years of age and hospitalized with hMPV-associated LRTI, SARI or if clinically diagnosed with severe pneumonia in the community. The main outcomes were prevalence of hMPV identified among children with hospitalized LRTI or SARI. We further calculated odds ratios for hMPV in cases with LRTI compared with non-LRTI controls. Pooled results were calculated using a random-effects model. RESULTS: Thirty studies were eligible for inclusion in the review. The prevalence of hMPV-LRTI/SARI among hospitalized and severe pneumonia cases was 4.7% [95% confidence interval (CI): 3.9-5.6, I2 = 95.0]. The case-control studies indicated that hMPV was 2.0-fold (95% CI: 0.9-4.4) more likely to be identified in LRTI cases (10.3%) than controls (6.0%). Three of 5 studies reported hMPV-associated LRTI case fatality risk, with a pooled estimate of 1.3% (95% CI: 0.3-2.9; I2 = 49). CONCLUSIONS: hMPV was associated with approximately 5% of LRTI/SARI hospitalizations or severe pneumonia cases in Africa.

Quality of life and physical activity among older adults living in institutions compared to the community.

BACKGROUND: The environment of older adults plays an important role in their well-being. It influences their quality of life and physical activity level. In South Africa, there is a dearth of literature concerning this issue. METHODS: An analytic cross-sectional sample of 80 older adults living in old age homes and the community was compared in terms of level of physical activity and quality of life. The study was conducted in Soweto, Johannesburg. A computer-generated random sample of older adults aged 60 years and above participated. The Physical Activity Scale for the Elderly (PASE) and RAND 36 questionnaires were used for data collection. Descriptive statistics were used to describe the sample. Unpaired t-tests, Pearson's correlation coefficient and chi-squared test explored the differences and associations between institutionalised and community living older adults. RESULTS: Quality of life in old age home dwellers (M = 68.53 ± 19.55) was significantly lower (p = 0.025) than in community dwellers (M = 77.74 ± 16.25). The mean physical activity score was also significantly (p = 0.000) lower in old age home dwellers (M = 20.18 ± 24.52) compared with community dwellers (M = 190.31 ± 82.81). CONCLUSION: Older adults who live in the community have a higher quality of life and physical activity levels compared with those who live in institutions (old age homes).
