The heme nitric oxide/oxygen-binding proteins (H-NOX) are bacterial homologues of the sensor domain of mammalian soluble guanylate cyclase (sGC), a multidomain enzyme that catalyzes the production of cyclic guanosine monophosphate (cGMP) in response to NO. In facultative anaerobes, H-NOX proteins sense nitric oxide (NO) and regulate various communal behaviors including biofilm formation, motility, virulence, and quorum sensing. Rupture of the proximal heme iron-histidine bond during the formation of a five-coordinate low-spin ferrous nitrosyl (5cLS Fe(II)-NO) heme is thought to be required for H-NOX activation, allowing them to interact with downstream signaling partners such as diguanylate cyclases (DGC), phosphodiesterases (PDE), or histidine kinases (HK).

Lowering low-density lipoprotein cholesterol (LDL-C) plasma levels is crucial for the prevention of primary and secondary cardiovascular diseases (CVDs). Many patients struggle to obtain goal LDL-C levels, despite the availability of several lipid-lowering medications, because of limited efficaciousness and unfavorable side effects. Proprotein convertase subtilisin/kexin type 9 (PCSK9) targeting has drawn interest recently as a novel approach to further lower cardiovascular (CV) risk.

Article Synopsis
  • Bangladesh has faced over 560 H5N1 outbreaks in poultry since 2007, primarily affecting commercial chicken farms that use imported vaccines which may not align with local virus strains.
  • A study examined the effectiveness of these vaccines by sampling feces from vaccinated and unvaccinated chicken farms across the country, finding only a small percentage of farms tested positive for the virus.
  • Results indicated that vaccinated farms had a lower detection of H5N1 virus, but due to low vaccination rates and limited positive samples, the overall effectiveness of the vaccine in reducing viral shedding remains uncertain.

Affordable and accessible tests for COVID-19 allow for timely disease treatment and pandemic management. SalivaDirect is a faster and easier method to implement than NPS sampling. Patients can self-collect saliva samples at home or in other non-clinical settings without the help of a healthcare professional.

Background: The use of patient health and treatment information captured in structured and unstructured formats in computerized electronic health record (EHR) repositories could potentially augment the detection of safety signals for drug products regulated by the US Food and Drug Administration (FDA). Natural language processing and other artificial intelligence (AI) techniques provide novel methodologies that could be leveraged to extract clinically useful information from EHR resources.

Objective: Our aim is to develop a novel AI-enabled software prototype to identify adverse drug event (ADE) safety signals from free-text discharge summaries in EHRs to enhance opioid drug safety and research activities at the FDA.

Whole-genome sequencing (WGS) of influenza A virus (IAV) is crucial for identifying diverse subtypes and newly evolved variants and for selecting vaccine strains. In developing countries, where facilities are often inadequate, WGS is challenging to perform using conventional next-generation sequencers. In this study, we established a culture-independent, high-throughput native barcode amplicon sequencing workflow that can sequence all influenza subtypes directly from a clinical specimen.

Article Synopsis
  • The study investigates the prevalence and risk factors of avian influenza virus (AIV) in pigeons and quails at live bird markets in Bangladesh, emphasizing its impact on poultry production and food security.
  • A total of 626 bird samples were collected between 2017 and 2021, revealing an overall AIV prevalence of 25.56%, with quails showing a higher rate (38.75%) compared to pigeons (17.36%).
  • Key factors contributing to higher AIV prevalence include vendors having waterfowl, sourcing birds from wholesale markets, and mixing sick birds with healthy ones, indicating unsafe practices in live bird markets.

Rodents and shrews live in close proximity to humans and have been identified as important hosts of zoonotic pathogens. This study aimed to detect Group A rotavirus (RVA) and its potential risk factors in rodents and shrews in Bangladesh. We captured 417 small mammals from 10 districts with a high degree of contact between people and domestic animals and collected rectal swab samples between June 2011 and October 2013.

Coronavirus disease 19 (COVID-19)-caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2)-has spread rapidly around the world. The global shortage of equipment and health care professionals, diagnostic cost, and difficulty in collecting nasopharyngeal swabs (NPSs) necessitate the use of an alternative specimen type for SARS-CoV-2 diagnosis. In this study, we investigated the use of saliva as an alternative specimen type for SARS-CoV-2 detection.

This is the first study that explored the self-reported dietary habits of acute psychiatric inpatients. We found that 75% of the psychiatric inpatients have an unhealthy diet, which correlates with higher body mass index (BMI) and lower education level. We also found an increased sugar consumption in inpatients with schizophrenia.

Article Synopsis
  • - Rotavirus A (RVA) causes severe diarrhea in humans and animals, with animal-to-human transmission contributing to strain diversity in humans.
  • - In a study, feces from 416 bats were tested for RVA, revealing a 7% prevalence in Pteropus medius and 2% in Rousettus leschenaultii, while no RVA was found in Taphozous melanopogon.
  • - The identified RVA strains in bats were similar to those found in humans (G1 and G8), highlighting the need for monitoring wildlife to understand how zoonotic pathogens evolve and spread.

  • Group A rotavirus is a significant cause of severe diarrhea in newborn calves and goat kids, with a study conducted in Bangladesh revealing an 11.7% infection rate among 520 tested animals.
  • Cattle showed a 6.2% infection rate while goats had a higher rate of 16.5%, and various G and P genotypes were identified, with G8 and P[1] being the most common.
  • The study emphasizes the need for ongoing rotavirus monitoring in livestock to understand genetic diversity and the potential for zoonotic transmission.

Background and Purpose- Endovascular thrombectomy (EVT) is effective for acute ischemic stroke with large vessel occlusion and National Institutes of Health Stroke Scale (NIHSS) ≥6. However, EVT benefit for mild deficits large vessel occlusions (NIHSS, <6) is uncertain. We evaluated EVT efficacy and safety in mild strokes with large vessel occlusion.

In a group of 22 healthy pigs aged between 4 and 6 months, 2 pigs became ill with high fever, complete anorexia, cough and abnormal swaying movements on 22 June 2015. One of them died on June 24 and the second died on July 3. Shortly after, the remaining pigs also fell ill and died from the same illness by 10 August 2015.

Resistance to carbapenem antibiotics through the production of New Delhi metallo-β-lactamase-1 (NDM-1) constitutes an emerging challenge in the treatment of bacterial infections. To monitor the possible source of the spread of these organisms in Dhaka, Bangladesh, we conducted a comparative analysis of wastewater samples from hospital-adjacent areas (HAR) and from community areas (COM), as well as public tap water samples, for the occurrence and characteristics of NDM-1-producing bacteria. Of 72 HAR samples tested, 51 (71%) samples were positive for NDM-1-producing bacteria, as evidenced by phenotypic tests and the presence of the gene, compared to 5 of 41 (12.
