Background: The increased emphasis on pneumonia-related performance measures and patient outcomes has led hospitals to implement multifaceted approaches to quickly identify patients with community-acquired pneumonia (CAP), start timely therapy and reduce readmission. However, there has been minimal focus on duration of therapy (DOT) and patients often receive prolonged antibiotic courses. The IDSA and American Thoracic Society (IDSA/ATS) CAP guidelines recommend 5 days of therapy for clinically stable patients that quickly defervesce and stewardship teams are well positioned to influence prescribing practices...

PURPOSE: The Child Depression Inventory (CDI) is a commonly used measure of depression among youth and has been used in studies conducted in sub-Saharan Africa demonstrating positive effects of financial asset-building interventions on physical and mental health outcomes. However, before we can be certain that asset building does indeed improve mental health functioning, we must first be sure that the instruments used to measure mental health in this population are valid and culturally appropriate...

Introduction: The quality of clinical care can be reliably measured in multiple settings using standardised patients (SPs), but this methodology has not been extensively used in Sub-Saharan Africa. This study validates the use of SPs for a variety of tracer conditions in Nairobi, Kenya, and provides new results on the quality of care in sampled primary care clinics. Methods: We deployed 14 SPs in private and public clinics presenting either asthma, child diarrhoea, tuberculosis or unstable angina...

In sub-Saharan Africa (SSA), youths (23 years or younger)-who account for almost half the population-are particularly vulnerable to poverty and exclusion from financial markets and intermediaries. In addition, a significant factor in the financial instability of the region appears to be the economic functioning of its youths. In recent years, social work interventions throughout the region have focused on investing in the economic functioning of youths. This study looked at baseline data from one such intervention in Kenya (N = 3,965), using the financial capabilities framework to evaluate the factors related to youths' saving behaviors...

Alphaviruses, such as chikungunya virus, and flaviviruses, such as dengue virus, are (re)-emerging arboviruses that are endemic in tropical environments. In Africa, arbovirus infections are often undiagnosed and unreported, with febrile illnesses often assumed to be malaria. This cross-sectional study aimed to characterize the seroprevalence of alphaviruses and flaviviruses among children (ages 5-14, n = 250) and adults (ages 15 ≥ 75, n = 250) in western Kenya. Risk factors for seropositivity were explored using Lasso regression...

BACKGROUND: Radiographic study of developing teeth provides a reliable indication of chronological age. In Kenya, dentists are often required to estimate age. However, there is a paucity of publications on the performance of dental age estimation methods. AIM: To determine the accuracy of Willems' method of dental age estimation. SUBJECTS AND METHODS: A cross-sectional study was done at The University of Nairobi Dental Hospital. Panoramic radiographs of children aged 3...

A DRT protein was identified and proved to be involved in the poplar arsenic resistance through comparative proteomics analysis between arsenic sensitive and resistant cultivars. Arsenic pollution in soil has been a serious problem all over the world. It is very important to dissect plants arsenic stress-response mechanisms in phytoremediation. In this study, arsenate-tolerant Populus deltoides cv. 'zhonglin 2025' and arsenate-sensitive Populus × euramericana cv. 'I-45/51' were screened from 10 poplar varieties...

OBJECTIVE: Physical activity (PA) is beneficial for health, yet most African American women do not achieve recommended levels. Successful, sustainable strategies could help to address disparities in health outcomes associated with low levels of PA. The Learning and Developing Individual Exercise Skills (L.A.D.I.E.S.) for a Better Life study compared a faith-based and a secular intervention for increasing PA with a self-guided control group. DESIGN SETTING AND PARTICIPANTS: This cluster randomized, controlled trial was conducted from 2010 - 2011 in African American churches (n=31) in suburban North Carolina...

Rift Valley fever virus (RVFV) is a zoonotic arbovirus affecting livestock and people. This study was conducted in western Kenya where RVFV outbreaks have not previously been reported. The aims were to document the seroprevalence and risk factors for RVFV antibodies in a community-based sample from western Kenya and compare this with slaughterhouse workers in the same region who are considered a high-risk group for RVFV exposure. The study was conducted in western Kenya between July 2010 and November 2012. Individuals were recruited from randomly selected homesteads and a census of slaughterhouses...

Efforts to eliminate mother-to-child transmission of HIV in Tanzania are guided by a four-prong strategy advocated by the World Health Organization (WHO). Prong 2, prevention of unintended pregnancies among women living with HIV, has, however, received the least attention and contraceptive use to prevent unintended pregnancies remains low. This study explored the perceived barriers to the use of modern methods of contraception, and factors influencing contraceptive choice among HIV-positive women in urban Dar-es-Salaam, Tanzania...

BACKGROUND: Lymphatic filariasis (LF) is a debilitating disease associated with extensive disfigurement and is one of a diverse group of diseases referred to as neglected tropical diseases (NTDs) which mainly occur among the poorest populations. In line with global recommendations to eliminate LF, Kenya launched its LF elimination programme in 2002 with the aim to implement annual mass drug administration (MDA) in order to interrupt LF transmission. However, the programme faced financial and administrative challenges over the years such that sustained annual MDA was not possible...

The process of base excision repair (BER) recognizes and repairs small lesions or inappropriate bases on DNA through either a short-patch or long-patch pathway. The enzymes involved in BER have been well-characterized on DNA substrates, and, somewhat surprisingly, many of these enzymes, including several DNA glycosylases, AP endonuclease (APE), FEN1 endonuclease, and DNA ligases, have been shown to have activity on DNA substrates within nucleosomes. DNA polymerase β (Pol β), however, exhibits drastically reduced or no activity on nucleosomal DNA...

BACKGROUND: Promoting access to medicines requires concurrent efforts to strengthen quality assurance for sustained impact. Although problems of substandard and falsified medicines have been documented in low- and middle-income countries, reliable information on quality is rarely available. OBJECTIVE: The aim of this study was to validate an alternative post-market surveillance model to complement existing models. METHODS: The study used standardized patients or mystery clients (people recruited from the local community and trained to pose as real patients) to collect medicine samples after presenting a pre-specified condition...

OBJECTIVE: This analysis was focused on 1-year maternal and infant follow-up of a randomized trial that tested a weight management intervention conducted during pregnancy. METHODS: One hundred fourteen women with obesity (mean BMI 36.7 kg/m(2) ) were randomly assigned at a mean of 15 weeks gestation to a weight management intervention or usual care control condition. The intervention ended at delivery and resulted in less gestational weight gain and a lower proportion of large-for-gestational-age newborns among intervention compared with control participants...

BACKGROUND: Problems with misallocation and redirection of critical resources and benefits intended for PLHIV are not uncommon in Kenya. This study explores corruption in Kenya's HIV response system and the implications for health outcomes from the perspective of people living with HIV (PLHIV). Although they might not be directly responsible for health care fund management, PLHIV and their advocacy efforts have been central to the development of HIV system response and they have a vested interest in ensuring proper governance...

BACKGROUND: Rates of maternal mortality and morbidity vary markedly, both between and within countries. Documenting these variations, in a very unequal society like South Africa, provides useful information to direct initiatives to improve services. The study describes inequalities over time in access to maternal health services in South Africa, and identifies differences in maternal health outcomes between population groups and across geographical areas. METHODS: Data were analysed from serial population-level household surveys that applied multistage-stratified sampling...
