Mayer-Rokitansky-Küster-Hauser syndrome (MRKHS) is a rare congenital disorder characterized by agenesis of the uterus and upper two-thirds of the vagina. It affects around 1 in 4000-5000 females and is of two types: type 1, also known as isolated Müllerian aplasia or Rokitansky, which involves only uterovaginal agenesis, and type 2, presents as uterovaginal agenesis along with renal, cardiac, and other organ anomalies. Despite the absence of vaginal and uterine structures, individuals with MRKHS typically present with normal secondary sexual characteristics and ovarian functions.

Introduction/objectives: Insomnia is a common sleep disorders that affects most individuals in the United States, and worldwide. Insomnia is linked with an increased risk of atrial fibrillation (AF) in adults, although the strengths of association were weak, especially in the elderly population. AF is estimated to affect approximately 3 to 6 million people in the United States.

Introduction: From 1996 to 2006, Nepal experienced a decade-long armed conflict that adversely impacted survivors of torture. The conflict posed threats to various facets of their lives, such as men-tal health, socio-economic status, human rights, and the process of reintegration into their original communities. This study was done with the survivors of torture from the armed conflict.

Article Synopsis
  • The One Health (OH) approach to combat antimicrobial resistance (AMR) is gaining recognition, but there’s a lack of clear guidance on implementing effective surveillance across different sectors.
  • In Nepal, the Tricycle Project utilized a multi-stage method to collect samples from humans, poultry, and wastewater to assess the prevalence of ESBL-producing bacteria.
  • The study found the highest prevalence of ESBL-producing bacteria in wastewater (91%), followed by bloodstream infections in humans (49%), poultry (38.6%), and healthy pregnant women (15%), leading to important insights for improving waste disposal and AMR control strategies.

  • * Results showed that heat treatment significantly reduced the total plate count of bacteria more effectively than HPP, but both methods minimized yeast, mold, and lactic acid bacteria compared to untreated milk.
  • * HPP at 600 MPa for 5 minutes effectively extended the milk's shelf-life by three weeks without affecting its pH, color, protein, or fat content, suggesting it as a viable alternative to heat treatment.*

  • The study assesses ChatGPT's ability to categorize nephrology patient messages as non-urgent, urgent, or emergent, crucial for timely medical care.
  • In trials involving 150 simulated messages, ChatGPT showed high accuracy, correctly triaging 93% of messages in both attempts, with slight variations in overestimations and underestimations.
  • The findings suggest that AI, like ChatGPT-4, could effectively improve patient communication triage in outpatient settings, enhancing operational efficiency and care quality.

Seafood is abundant in high-quality protein, healthy fats (n-3 and n-6 PUFAs), minerals (calcium, magnesium, copper, selenium, and so on), and vitamin D. Functional compounds in seafood can protect against lifestyle-related diseases. Having had all the merits mentioned, it is also a highly putrefiable food item.

Rapid cooling in fast-rate manufacturing processes such as additive manufacturing and stamp forming limits the development of crystallinity in semicrystalline polymer nanocomposites and, therefore, potential improvements in the mechanical performance. While the nucleation, chain mobility, and crystallization time from rapid cooling are known competing mechanisms in crystallization, herein we elucidate that the crystalline morphology and architecture also play a key role in tuning the mechanical performance. We explore how modifying the spherulite morphology via a cellulose nanocrystal (CNC) and graphene nanoplatelet (GNP) hybrid system in their pristine form can improve or preserve the mechanical properties of poly(ether ether ketone) (PEEK) nanocomposites under two extreme cooling rates (fast -460 °C/min and slow -0.

Background: Our goal was to identify what impact chronic kidney disease (CKD) and its associated risk factors, such as body mass index (BMI), diabetes and hypertension, have on preeclampsia and other adverse pregnancy outcomes in the CKD population.

Methods: This was a population-based cohort study of women with CKD who had a pregnancy from 2010 to 2022 (n = 95). At the time of the woman's pregnancy, data was collected on demographics, clinical measures, BMI, CKD etiology and other renal parameters.

Identifying factors that significantly affect drivers that are repeatedly involved in traffic violations or non-fatal crashes (defined here as recidivist drivers) is very important in highway safety studies. This study sought to understand the relationship between a set of variables related to previous driving violations and the duration between a previous non-fatal crash and a subsequent fatal crash, taking into account the age and gender of the driver. By identifying the characteristics of this unique driver population and the factors that influence the duration between their crash events strategies can be put in place to prevent the occurrence of future and potentially fatal crashes.

  • Subunit vaccines need adjuvants to stimulate an immune response, but current options often have safety concerns or limited effectiveness.
  • This study tested mannose-lipopeptide ligands as a potential way to enhance the immune response to a vaccine using a specific Group A Streptococcus (GAS) antigen.
  • The results showed that a particular mannose ligand significantly increased the production of protective antibodies without the negative side effects associated with traditional adjuvants, indicating its potential as a safer vaccine enhancer.

An increase in the consumption of carbohydrate-rich cereals over past few decades has led to increased metabolic disorders in population. This nutritional imbalance in diets may be corrected by substituting cereal grains with pseudocereals that are richer in high-quality proteins, dietary fibers, unsaturated fats, and bioactive compounds (e.g.

Introduction: Proteinuria is usually related with preeclampsia during pregnancy, although it can also be caused by other conditions such as renal disease or isolated proteinuria. Proteinuria during pregnancy can result in adverse fetomaternal outcomes. The study aimed to find the prevalence of proteinuria among pregnant women admitted to the Department of Obstetrics and Gynaecology of a tertiary care centre.

Peptide-based vaccines can trigger highly specific immune responses, although peptides alone are usually unable to confer strong humoral or cellular immunity. Consequently, peptide antigens are administered with immunostimulatory adjuvants, but only a few are safe and effective for human use. To overcome this obstacle, herein a peptide antigen was lipidated to effectively anchor it to liposomes and emulsion.
