Association of moderate alcohol intake with in vivo amyloid-beta deposition in human brain: A cross-sectional study
by Jee Wook Kim, Min Soo Byun, Dahyun Yi, Jun Ho Lee, Kang Ko, So Yeon Jeon, Bo Kyung Sohn, Jun-Young Lee, Yu Kyeong Kim, Seong A Shin, Chul-Ho Sohn, Dong Young Lee, for the KBASE Research Group BackgroundAn emerging body of literature has indicated that moderate alcohol intake may be protective against Alzheimer disease (AD) dementia. However, little information is available regarding whether moderate alcohol intake is related to reductions in amyloid-beta (A β) deposition, or is protective via amyloid-independent mechanisms in the living human brain. Here we examined the associations of moderate alcohol intake with ...

Virological suppression and clinical management in response to viremia in South African HIV treatment program: A multicenter cohort study
ConclusionsIn this study, 90% virological suppression below the threshold of 1,000 copies/mL was observed in on-treatment analysis. However, this target was not met at the 50-copies/mL threshold or in intention-to-treat analysis. Clinical management in response to viremia was profoundly delayed, prolonging the duration of viremia and potential for transmission. Diagnostic tools to establish the cause of viremia are urgently needed to accelerate clinical decision-making. (Source: PLoS Medicine)

Changes in maternal age and prevalence of congenital anomalies during the enactment of China's universal two-child policy (2013 –2017) in Zhejiang Province, China: An observational study

Estimating progress towards meeting women ’s contraceptive needs in 185 countries: A Bayesian hierarchical modelling study
ConclusionsIn this study, we observed that large gaps remain in meeting family-planning needs. The projected increase in the number of women with need for family planning will create challenges to expand family-planning services fast enough to fulfil the growing need. Monitoring of family-planning indicators for all women, not just MWRA, is essential for accurately monitoring progress towards universal access to sexual and reproductive healthcare services —including family planning—by 2030 in the SDG era with its emphasis on ‘leaving no one behind.’ (Source: PLoS Medicine)

Advances in cervical cancer prevention: Efficacy, effectiveness, elimination?
by Karin Sundstr öm, K. Miriam Elfström With major advances in understanding the infectious etiology of cervical cancer, preventive medicine has obtained highly promising new tools. Human papillomavirus (HPV) vaccines, together with a growing arsenal of HPV-based screening tests, have the potential to radically change public health but require diligent, large-scale implementation to reach the final goal: the elimination of cervical cancer.

Prevalence and genetic profiles of isoniazid resistance in tuberculosis patients: A multicountry analysis of cross-sectional data
ConclusionsIn this study, the prevalence of Hr-TB among TB patients was higher than the prevalence of rifampicin resistance globally. Many patients with Hr-TB would be missed by current diagnostic algorithms driven by rifampicin testing, highlighting the need for new rapid molecular technologies to ensure access to appropriate treatment and care. The low prevalence of resistance to pyrazinamide and fluoroquinolones among patients with Hr-TB provides further justification for the recommended modified treatment regimen. (Source: PLoS Medicine)

ConclusionsOur findings suggest that efforts to close the quality gap would still produce substantial benefits at current levels of access or utilization. With estimated mortality rate declines of 21% –32% on average, gains from this first step would be significant if quality was improved for selected antenatal, intrapartum, and postnatal interventions to benefit pregnant women and newborns seeking care. Interventions provided at or around the time of childbirth are most critical and accounted for 64% of the impact overall estimated in this quality improvement analysis. (Source: PLoS Medicine)

ConclusionsOur study suggests that geographic targeting substantially improves the cost-effectiveness and impact of oral cholera vaccination campaigns. Districts with the poorest access to improved water and sanitation are not the same as districts with the greatest historical cholera incidence. While OCV campaigns can improve cholera control in the near term, without rapid progress in developing water and sanitation services or dramatic increases in OCV supply, our results suggest that vaccine use alone is unlikely to allow us to achieve the 2030 goal.

Homogeneity in the association of body mass index with type 2 diabetes across the UK Biobank: A Mendelian randomization study
by Michael Wainberg, Anubha Mahajan, Anshul Kundaje, Mark I. McCarthy, Erik Ingelsson, Nasa Sinnott-Armstrong, Manuel A. Rivas BackgroundLifestyle interventions to reduce body mass index (BMI) are critical public health strategies for type 2 diabetes prevention. While weight loss interventions have shown demonstrable benefit for high-risk and prediabetic individuals, we aimed to determine whether the same benefits apply to those at lower risk. Methods and findingsWe performed a multi-stratum Mendelian randomization study of the effect size of BMI on diabetes odds in 287,394 unrelated individuals of self-reported white Brit...

Incidence of maternal peripartum infection: A systematic review and meta-analysis
ConclusionsIn this study, we observed pooled infection estimates of almost 4% in labour and between 1% –2% of each infection outcome postpartum. This indicates maternal peripartum infection is an important complication of childbirth and that preventive efforts should be increased in light of antimicrobial resistance. Incidence risk appears lower than modelled global estimates, although differences in definitions limit comparability. Better-quality research, using standard definitions, is required to improve comparability between study settings and to demonstrate the influence of risk factors and protective interventi...
