Background Active case finding is a top priority for the global control of tuberculosis, but robust evidence for its effectiveness in high-prevalence settings is lacking. We sought to evaluate the effectiveness of household-contact investigation, as compared with standard, passive measures alone, in Vietnam. Methods We performed a cluster-randomized, controlled trial at clinics in 70 districts (local government areas with an average population of approximately 500,000 in urban areas and 100,000 in rural areas) in eight provinces of Vietnam...

Background: Urban heat island (UHI) effect, the ubiquitous consequence of urbanization, is considered to play a major role in population expansion of numerous insects. Cryptotympana atrata and Hyalessa fuscata are the most abundant cicada species in the Korean Peninsula, where their population densities are higher in urban than in rural areas. We predicted a positive relationship between the UHI intensities and population densities of these two cicada species in metropolitan Seoul. Methods: To test this prediction, enumeration surveys of cicada exuviae densities were conducted in 36 localities located within and in the vicinity of metropolitan Seoul...

Development of robust, cost-effective, and efficient catalyst is extremely necessary for oxygen reduction reaction (ORR) in fuel cell applications. Herein, we reported a well-defined nanostructured catalyst of highly dispersed CuAg@Ag core-shell nanoparticles (NPs) encapsulated nitrogen-doped graphene nanosheets (CuAg@Ag/N-GNS) to exhibit superior catalytic activity towards the ORR in alkaline medium. The synergistic effects produced from the unique properties of CuAg@Ag core-shell NPs and N-GNS nanosheets made such a novel nanohybrid to display a comparable catalytic behaviour to commercial Pt/C product...

OBJECTIVES: Ischaemic heart diseases (IHDs) are a leading cause of death worldwide. Although prescribing according to guidelines improves health outcomes, it remains suboptimal. We determined whether interventions targeted at healthcare professionals are effective to enhance prescribing and health outcomes in patients with IHDs. METHODS: We systematically searched PubMed and EMBASE for studies published between 1 January 2000 and 31 August 2017. We included original studies of interventions targeted at healthcare professionals to enhance prescribing guideline-recommended medications for IHDs...

OBJECTIVES: Postoperative atrial fibrillation (AF) following coronary artery bypass graft surgery (CABG) is significantly associated with reduced survival, but poor characterisation and inconsistent definitions present barriers to developing effective prophylaxis and management. We sought to address this knowledge gap. METHODS: From 2002 to 2010, 11 239 consecutive patients without AF underwent isolated CABG at five sites. Clinical data collected for the Society of Thoracic Surgeons (STS) Database were augmented with details on AF detected via continuous in-hospital ECG/telemetry monitoring to assess new-onset post-CABG AF (adjusted for STS risk of mortality); time to first AF; durations of first and longest AF episodes; total in-hospital time in AF; number of in-hospital AF episodes; operative mortality; stroke; discharge in AF; and length of stay (LOS)...

Indochina is a biodiversity hot spot and harbors a high number of endemic species, most of which are poorly studied. This study explores the genetic structure and reproductive system of the threatened endemic timber species Dalbergia cochinchinensis and Dalbergia oliveri using microsatellite data from populations across Indochina and relates it to landscape characteristics and life-history traits. We found that the major water bodies in the region, Mekong and Tonle Sap, represented barriers to gene flow and that higher levels of genetic diversity were found in populations in the center of the distribution area, particularly in Cambodia...

The so-called "Baekdudaegan" (BDDG), a mountain range that stretches along the Korean Peninsula, has been recently proposed as a major "southern" glacial refugium for boreal or temperate plant species based on palaeoecological and, especially, genetic data. Genetic studies comparing genetic variation between population occurring on the BDDG and more northern ones (i.e. in NE China and/or in Russian Far East) are, however, still too few to draw firm conclusions on the role of the BDDG as a refugium and a source for possible northward post-glacial recolonizations...

Coffee yields are adversely affected by plant-parasitic nematodes and the pathogens are largely under-reported because a simple and reliable identification method is not available. We describe a PCR-based approach to rapidly detect and quantify the major Pratylenchus and Meloidogyne nematode species that are capable of parasitising coffee. The procedure was applied to soil samples obtained from a number of coffee farms in Brazil, Vietnam and Indonesia to assess the prevalence of these species associated both with coffee (Coffea arabica and C...

Background: Hyperammonemia, a relatively uncommon condition characterized by elevated ammonia levels in the blood, presents with varied physiological etiologies that may send patients to the intensive care unit (ICU) with encephalopathy. An immediate decrease in ammonia levels is necessary to avert neurological damage. However, due to the multifaceted nature of hyperammonemia, a definite determination of etiology is not always possible. Objective: This case report examines the clinical and economic impact of a pharmacist in managing acute hyperammonemia of unknown etiology in a 62-year-old Hispanic man who had recently been diagnosed with metastatic medullary thyroid cancer and associated hypercalcemia...

Platycodon grandiflorum contains triterpenoid saponins, such as platycodin D and platyconic acid A, and acts as a multifold nutritious compound. Our previous research demonstrated that Platycodon grandiflorum-derived saponin (PS) improves high-fat diet-induced non-alcoholic steatohepatitis and inhibits osteoclast differentiation. The pivotal effects of PS on inflammatory mechanism were suppressed NF-κB and matrix metalloproteinase (MMPs). However, the effects of PS on skeletal muscle damage remain unknown...
