Rotavirus diarrhea in hospitalized children under 5 years of age in Vientiane, Lao PDR, 2009-2015.

Background: Diarrhea is a leading cause of death in children <5 years worldwide, causing an estimated 215,000 deaths in 2013. This evaluation tracks the epidemiologic patterns and most common rotavirus genotypes among hospitalized children in this age group with acute gastroenteritis in Lao PDR.

Methods: Children <5 years in a central tertiary hospital in the capital city were prospectively enrolled into the surveillance platform during January 2009-December 2015.

Some sustained improvements in pneumonia case management four and five years following implementation of paediatric hospital guidelines in Lao PDR.

In 2010, WHO paediatric hospital guidelines were implemented in Lao PDR, along with training workshops and feedback audits, achieving significant improvements in pneumonia case management when assessed one-year post-intervention. The sustainability of these improvements is hereby assessed, four and five years post-intervention. Medical records of children aged 1-59 months, diagnosed with pneumonia in 2010, 2011, 2014 and 2015 from a central Lao hospital were reviewed.

A Qualitative Study of Provider Perceptions of Influences on Uptake of Pediatric Hospital Guidelines in Lao PDR.

Strategies to improve the quality of hospital care are needed if ongoing gains in child health and survival are to be made. We previously reported on improvements in the quality of case management in hospitals following a guideline-based intervention in Lao PDR, with variation in the degree of change achieved between clinical conditions. This study aims to understand the factors that influenced the uptake of the guideline-based intervention, and its impact on care.

APOE Genotype in the Ethnic Majority and Minority Groups of Laos and the Implications for Non-Communicable Diseases.

Background: Increasing age is associated with elevated risk of non-communicable diseases, including dementia and Alzheimer's disease (AD). The apolipoprotein E (APOE) ε4 allele is a risk factor not only for AD, but also for cognitive decline, depressive symptoms, stroke, hypertension, coronary heart disease, cardiovascular disease, and diabetes. The Lao People's Democratic Republic (Laos) is undergoing development; consequently, life expectancy has risen.

Epidemiological study of Japanese encephalitis virus in Vientiane, Lao PDR, in 1990s.

Phylogenetic analysis of Japanese encephalitis virus (JEV) was conducted using core-premembrane and envelope gene sequence data of two strains from Vientiane, Lao People's Democratic Republic, in 1993 and five from Okinawa, Japan, in 2002 and 2003, and previously published strains. The two Vientiane strains designated as LaVS56 and LaVS145 belonged to genotype 1 (G1) and the same subcluster of G1 as Australian strain in 2000, Thai strains in 1982-1985 and 2004-2005, and Vietnamese strain in 2005, but were distinct from the subcluster of recently distributing G1 strains widely in Asia including Okinawan strains and recent Lao strain in 2009. These clusters with own distinct distributions indicated involvements of different mechanisms and routes of spreading viruses and clarified that Australian G1 strain is from Southeast Asia, not from East Asia.

Implementing WHO hospital guidelines improves quality of paediatric care in central hospitals in Lao PDR.

Objectives: To evaluate the impact of implementing a multifaceted intervention based on the WHO Pocketbook of Hospital Care for Children on the quality of case management of common childhood illnesses in hospitals in Lao PDR.

Methods: The quality of case management of four sentinel conditions was assessed in three central hospitals before and after the implementation of the WHO Pocketbook as part of a broader mixed-methods study. Data on performance of key steps in case management in more than 600 admissions were collected by medical record abstraction pre- and post-intervention, and change was measured according to the proportion of cases which key steps were performed as well as an overall score of case management for each condition.

Clinically unapparent infantile thiamin deficiency in Vientiane, Laos.

Background: Beriberi occurs in Vientiane, Lao PDR, among breastfed infants. Clinical disease may be the tip of an iceberg with subclinical thiamin deficiency contributing to other illnesses. Thiamin treatment could improve outcome.

Erythrocyte transketolase activity, markers of cardiac dysfunction and the diagnosis of infantile beriberi.

Background: Infantile beriberi is a potentially lethal manifestation of thiamin deficiency, associated with traditional post-partum maternal food avoidance, which persists in the Lao PDR (Laos). There are few data on biochemical markers of infantile thiamin deficiency or indices of cardiac dysfunction as potential surrogate markers.

Methodology/principal Findings: A case control study of 47 infants with beriberi and age-matched afebrile and febrile controls was conducted in Vientiane, Laos.

Provider performance in treating poor patients--factors influencing prescribing practices in lao PDR: a cross-sectional study.

Background: Out-of-pocket payments make up about 80% of medical care spending at hospitals in Laos, thereby putting poor households at risk of catastrophic health expenditure. Social security schemes in the form of community-based health insurance and health equity funds have been introduced in some parts of the country. Drug and Therapeutics Committees (DTCs) have been established to ensure rational use of drugs and improve quality of care.

Causes of community-acquired bacteremia and patterns of antimicrobial resistance in Vientiane, Laos.

There is no published information on the causes of bacteremia in the Lao PDR (Laos). Between 2000 and 2004, 4512 blood culture pairs were taken from patients admitted to Mahosot Hospital, Vientiane, Laos, with suspected community-acquired bacteremia; 483 (10.7%) cultures grew a clinically significant community-acquired organism, most commonly Salmonella enterica serovar typhi (50.

Dietary and socio-economic factors associated with beriberi in breastfed Lao infants.

A case-control study was conducted to investigate the dietary and socio-economic factors associated with beriberi in infants attending three public hospitals in Vientiane, Lao PDR. Forty-three breast-feeding infants with a median (range) age of 3 (1-9) months were admitted with beriberi. This was defined as the presence of signs of congestive heart failure or shock in the absence of fever or other signs of sepsis, hypovolaemia or cardiac abnormalities, with rapid clinical improvement following parenteral thiamine.
