BACKGROUND: The prevalence of PPHN has been estimated at 1.9 per 1000 live births. After the discovery of iNO's, its efficacy and benefit in PPHN is well established. Even in the best of centers equipped with iNo and ECMO the mortality is around 20%. Also, iNO is expensive and difficult to administer and monitor which makes it difficult choice in our part of the world. Furthermore About 40% of patients do not respond or have rebound pulmonary hypertension after discontinuation. Owing to these reasons, other treatment modalities like phosphodiesterase inhibitors such as Sildenafil need to be evaluated...

Porcine epidemic diarrhea (PED), which is caused by porcine epidemic diarrhea virus (PEDV), is an acute, highly contagious enteric disease characterized by severe watery diarrhea, vomiting, dehydration, and high mortality in suckling piglets. A real-time reverse-transcription recombinase polymerase amplification assay (RT-RPA) was developed based on the nucleocapsid gene of PEDV. RT-RPA assay was performed at 40 °C for 20 min. The assay could detect both the classical and variant PEDV strains, and there was no cross-reaction with other pathogens tested...

Antibiotic resistance, the ability of some bacteria to resist antibiotic drug, has been a major global health burden due to the extensive use of antibiotic agents. Antibiotic resistance is encoded via respective genes, hence the specific detection of these genes is necessary for diagnostic and treat of antibiotic resistance cases. Conventional methods for monitoring antibiotic resistance genes require sample to be transported to a central laboratory for tedious and sophisticated tests, which is grueling and time-consuming...

The health and well-being of cattle is a significant concern for global agricultural output. In dairy production within low and middle income countries (LMICs), there is a significant biosensing challenge in detecting sexually transmitted infection (STI) pathogens during animal husbandry, due in part to difficulties associated with the limited infrastructure for veterinary medicine. Here we demonstrate low-cost, multiplexed and sample-to-answer paper-origami tests for the detection of three bovine infectious reproductive diseases in semen samples, collected at a test site in rural India...

Microfluidics has served as a technology for the design and development of a myriad of devices owing to their reduced reagent consumption rate and short sampling-to-result time. Chemotaxis is the movement of materials, particularly biological species, in response to the influence of chemical stimulation. Herein, we describe, for the first time, chemotactic behavior on a microfluidic paper-based analytical device (μPAD) to afford a distribution of products not obtainable under other (non-μPAD) experimental conditions using as a model enzyme-substrate system glucose oxidase (GOx) and glucose...

BACKGROUND: In the developing world, only a small minority of patients have access to radiological services. Over the past decade, technological developments of ultrasound equipment have led to the emergence of point-of-care ultrasonography (POCUS), which is widely used by healthcare professionals of nearly all specialties. We hypothesized that physicians with only basic POCUS training, but with telemedicine support, can use POCUS successfully in rural hospitals in sub-Saharan Africa...

BACKGROUND: Malaria rapid diagnostic tests (RDTs) are a great achievement in implementation of parasite based diagnosis as recommended by World Health Organization. A major drawback of RDTs is lack of positive controls to validate different batches/lots at the point of care. Dried Plasmodium falciparum-infected samples with the RDT target antigens have been suggested as possible positive control but their utility in resource limited settings is hampered by rapid loss of activity over time...

Panel data from the South African National Income Dynamics Study, a nationally representative sample of households (years 2008, 2010 and 2012), were used to examine the longitudinal association between religious involvement and depression risk. Approximately 89.6-91.8% identified themselves as religiously affiliated, while 88.0-90.3% perceived religion to be important in South Africa during the observed study periods. A short-term association between religious involvement and significant depressive symptomatology was not detected, but logistic regression models that accounted for the clustering of repeated observations within participants indicated that, over time, those with religious affiliations (aOR 0...

In contrast to the significant resources invested in diagnosis and prevention of C. difficile infection (CDI) in resource-rich settings, in resource-limited settings patients with community- and hospital-acquired diarrhea may not routinely be tested for CDI. Is CDI actually less frequent or severe in resource-limited settings, or might we be missing an important opportunity to prevent CDI-related morbidity and mortality (and to promote antibiotic stewardship) in these settings? Here, we review the literature to assess the overall burden of CDI in low- and middle-income countries...
