Background: The national malaria control programmes in Cambodia, Nepal, and Bhutan aim to achieve malaria elimination by 2025-2030. While the vivax malaria burden remains challenging, the consistent decline in falciparum malaria in these countries over the last five years suggests that the goal is achievable. However, unexpected cases in previously falciparum malaria-free districts continue to occur.

Background: Gene set tests can pinpoint genes and biological pathways that exert small to moderate effects on complex diseases like Type 2 Diabetes (T2D). By aggregating genetic markers based on biological information, these tests can enhance the statistical power needed to detect genetic associations.

Results: Our goal was to develop a gene set test utilizing Bayesian Linear Regression (BLR) models, which account for both linkage disequilibrium (LD) and the complex genetic architectures intrinsic to diseases, thereby increasing the detection power of genetic associations.

Article Synopsis
  • Peutz-Jeghers syndrome (PJS) is a rare genetic disorder that causes gastrointestinal polyps and skin pigmentation, leading to complications like abdominal pain and intestinal obstruction from intussusception.
  • A case study details a 36-year-old woman with symptoms such as flank pain and melena, who was diagnosed with PJS after imaging and surgery revealed jejuno-jejunal intussusception and multiple polyps.
  • PJS stems from mutations in the STK11 gene, and regular screenings are vital for detecting cancer and monitoring polyp growth, with surgical intervention recommended for significant polyps and intussusception cases.

Objective: Acute aortic dissection type A (AADA) is a condition that affects both genders and requires urgent surgical intervention as non-operative treatment is often associated with a poor prognosis. Studies have proven that less aggressive surgical treatments influence the outcome for female patients in the fields of several diseases. The purpose of this study was to report and analyze our results in the selective cohort of female patients with AADA to detect differences in the treatment of this group of patients.

The likelihood of antimicrobial failure in COVID-19 patients with bacterial superinfection arises from both phenotypic (biofilms) and genotypic mechanisms. This cross-sectional study aimed to determine the inhibitory concentrations of quinolones-nalidixic acid, norfloxacin, ciprofloxacin, ofloxacin, and levofloxacin-in biofilm formers (minimum biofilm inhibitory concentration [MBIC]) and nonformers (minimum inhibitory concentration [MIC]) and correlate inhibitory concentrations with plasmid-mediated quinolone resistance (PMQR) genes in quinolone-resistant bacteria isolated from COVID-19 inpatients. Quinolone-resistant bacteria (n = 193), verified through disc diffusion, were tested for quinolone inhibitory concentrations using broth microdilution and biofilm formation using microtiter plate methods.

Schwannomas, also known as neurilemmomas, are neurogenic, benign tumors of Schwann cells arising from peripheral nerve sheaths that may be present at almost any anatomical site. A primary mesenteric schwannoma is an extremely rare tumor, with only 12 cases reported in the literature to date. Preoperative diagnosis of mesenteric schwannomas is almost impossible because of the rarity of the case and their nonspecific symptoms.

  • Ascending-to-descending aortic bypass is a repair method for complex aortic coarctation, showing low early complications, but long-term results were previously unclear.
  • A study of 81 patients who had the procedure from 1985 to 2012 revealed 5, 10, and 20-year survival rates of 94%, 90%, and 85%, with no perioperative deaths and no significant complications related to the bypass.
  • Overall, this technique is considered safe with excellent long-term outcomes, improving systemic hypertension, and does not interfere with future surgeries through the same chest incision.

Background And Objective: Value-based payment programs link payments to the performance of providers on cost and quality of care to incentivize high-value care. To improve quality and lower costs, the Centers for Medicare and Medicaid Services (CMS) implemented the Quality Payment Program (QPP) for clinicians in 2017. Under the Medicare QPP, most eligible clinicians participate in one of the payment models: (a) Advanced Alternative Payment Models (A-APMs) through eligible APMs like Accountable Care Organizations (ACOs) or (b) the Merit-based Incentive Payment System (MIPS).

Genome-wide association studies (GWAS) provide valuable insights into the genetic architecture of complex traits, yet interpreting their results remains challenging due to the polygenic nature of most traits. Gene set analysis offers a solution by aggregating genetic variants into biologically relevant pathways, enhancing the detection of coordinated effects across multiple genes. In this study, we present and evaluate a gene set prioritization approach utilizing Bayesian Linear Regression (BLR) models to uncover shared genetic components among different phenotypes and facilitate biological interpretation.

Measuring the intracellular pH (pHi) is of interest for brain tumor diagnostics. Common metrics of CEST imaging like the amide proton transfer-weighted (APTw) MTR are pHi sensitive and allow differentiating malignant tumor from healthy tissue. Yet, the image contrast also depends on additional magnetization transfer effects and T1.

  • Clinical trials (CT) are essential for developing new medicines and require participant involvement, which is influenced by their attitudes and understanding of the trials.
  • A study at B.P. Koirala Institute of Health Sciences in Nepal assessed the knowledge and perceptions of 622 participants in a phase III CT, finding that a vast majority were literate, of indigenous backgrounds, and had not participated in a CT before.
  • Results showed that 91% of participants had adequate knowledge and 95.7% had a positive perception of CT, with most joining for disease protection and believing the trials benefit humanity, suggesting the need for future studies on knowledge before and after participation.

  • Hydrocele is a common condition involving fluid accumulation in the scrotum, leading to painless swelling, and has been minimally studied in Nepal.
  • A year-long study analyzed medical records from a surgical department in a tertiary care center, identifying cases of hydrocele surgery and gathering data on prevalence and patient demographics.
  • Findings revealed that out of 1812 surgeries, 95 were hydrocele-related, mainly non-communicating and unilateral; the majority of patients were around 50 years old, and 20% experienced postoperative complications.

During outbreaks of emerging infectious diseases, internationally connected cities often experience large and early outbreaks, while rural regions follow after some delay. This hierarchical structure of disease spread is influenced primarily by the multiscale structure of human mobility. However, during the COVID-19 epidemic, public health responses typically did not take into consideration the explicit spatial structure of human mobility when designing nonpharmaceutical interventions (NPIs).
