Efficacy and Safety of Prehospital Blood Transfusion in Traumatized Patients: A Systematic Review and Meta-Analysis.

Background: Approximately five million individuals have traumatic injuries annually. Implementing prehospital blood-component transfusion (PHBT), encompassing packed red blood cells (p-RBCs), plasma, or platelets, facilitates early hemostatic volume replacement following trauma. The lack of uniform PHBT guidelines persists, relying on diverse parameters and physician experience.

Current Approaches and Strategies Applied in First-in-class Drug Discovery.

First-in-class drug discovery (FICDD) offers novel therapies, new biological targets and mechanisms of action (MOAs) toward targeting various diseases and provides opportunities to understand unexplored biology and to target unmet diseases. Current screening approaches followed in FICDD for discovery of hit and lead molecules can be broadly categorized and discussed under phenotypic drug discovery (PDD) and target-based drug discovery (TBDD). Each category has been further classified and described with suitable examples from the literature outlining the current trends in screening approaches applied in small molecule drug discovery (SMDD).

Functional Evaluation of a Novel Homozygous ADCY3 Variant Causing Childhood Obesity.

Adenylate cyclase 3 () is a transmembrane protein predominantly expressed in the primary cilia of neurons. It plays a vital role in converting ATP to cAMP, a secondary messenger that regulates various downstream signaling pathways such as carbohydrates and lipids metabolism. Homozygous loss-of-function variants in the gene lead to severe early-onset obesity and insulin resistance whereas gain-of-function variants protect against obesity.

Gastrointestinal Sequelae of COVID-19: Investigating Post-Infection Complications-A Systematic Review.

These complications range from severe acute pancreatitis to colitis, adding complexity to diagnosis and management. A comprehensive database search was conducted using several databases.

New Onset of Acute and Chronic Hepatic Diseases Post-COVID-19 Infection: A Systematic Review.

The SARS-CoV-2 virus caused a pandemic in the 2020s, which affected almost every aspect of life. As the world is recovering from the effect of the coronavirus, the concept of post-COVID-19 syndrome has emerged. Multiple organ systems have been implicated, including the liver.

A rare case of an EBV-positive inflammatory follicular dendritic cell tumor of the spleen.

Epstein-Barr virus positive inflammatory pseudotumor follicular dendritic cell sarcoma (EBV+ FDCS) is a rare indolent neoplasm that presents primarily in the spleen and liver. We display a case of EBV+ FDCS in the spleen, its clinic-pathologic properties, and treatment. Our patient was evaluated following an incidental finding of a splenic mass on imaging after a traumatic injury.

Metachronous Tumours in the Head and Neck in a Retroviral Disease Positive Patient: A Case Report and Review of Literature.

Patients diagnosed with head and neck squamous cell carcinoma (HNSCC), particularly those seropositive for human immunodeficiency virus (HIV), face a heightened risk of second primary malignancies (SPMs), with common regions being the head, neck, lung, and oesophagus. This risk amplifies the severity of their clinical condition, as these SPMs contribute significantly to the mortality rates in patients with HNSCC. We detail a case of a young woman, seropositive for HIV, who developed a second squamous cancer in the nasopharynx after achieving remission from her initial oropharyngeal squamous cell carcinoma through chemo-radiotherapy.

Low-dose cryo-electron ptychography of proteins at sub-nanometer resolution.

Cryo-transmission electron microscopy (cryo-EM) of frozen hydrated specimens is an efficient method for the structural analysis of purified biological molecules. However, cryo-EM and cryo-electron tomography are limited by the low signal-to-noise ratio (SNR) of recorded images, making detection of smaller particles challenging. For dose-resilient samples often studied in the physical sciences, electron ptychography - a coherent diffractive imaging technique using 4D scanning transmission electron microscopy (4D-STEM) - has recently demonstrated excellent SNR and resolution down to tens of picometers for thin specimens imaged at room temperature.

Microbiological culture versus 16S/18S rRNA gene PCR-sanger sequencing for infectious keratitis: a three-arm, diagnostic cross-sectional study.

Background: To compare the diagnostic performance of microbiological culture and 16S/18S rRNA gene polymerase chain reaction (PCR)-Sanger sequencing for infectious keratitis (IK) and to analyse the effect of clinical disease severity on test performance and inter-test concordance.

Methods: This was a three-arm, diagnostic cross-sectional study. We included all eligible patients who presented with presumed bacterial/fungal keratitis to the Queen's Medical Centre, Nottingham, UK, between June 2021 and September 2022.

Computational models for improving surveillance for the early detection of direct introduction of cassava brown streak disease in Nigeria.

Cassava is a key source of calories for smallholder farmers in sub-Saharan Africa but its role as a food security crop is threatened by the cross-continental spread of cassava brown streak disease (CBSD) that causes high yield losses. In order to mitigate the impact of CBSD, it is important to minimise the delay in first detection of CBSD after introduction to a new country or state so that interventions can be deployed more effectively. Using a computational model that combines simulations of CBSD spread at both the landscape and field scales, we model the effectiveness of different country level survey strategies in Nigeria when CBSD is directly introduced.

Efficacy and safety of emodepside compared with albendazole in adolescents and adults with hookworm infection in Pemba Island, Tanzania: a double-blind, superiority, phase 2b, randomised controlled trial.

Background: Human hookworm is a cause of enormous global morbidity. Current treatments have insufficient efficacy and their extensive and indiscriminate distribution could also result in drug resistance. Therefore, we tested the efficacy and safety of emodepside, a strong anthelmintic candidate that is currently undergoing clinical development for onchocerciasis and soil-transmitted helminth infections.

Variations in fluorescence properties of humic acids from calcareous soils amended with different swine manures in a long-term soil experiment.

Molecular properties of soil humic acid (HA) can play an important role in the mechanisms regulating plant nutrient availability. This study explores how the structure of HA is altered by long-term treatment with different forms of swine manure and how these changes may influence nutrient availability. Liquid swine manure (LSM), solid swine manure (SSM), and swine manure compost (SMC) were applied to a calcareous soil over 17 years in a long-term soil fertility study.

A Randomized Controlled Trial to Optimize Antivenom Therapy for Carpet Viper (Echis romani)-Envenomed Children in Nigeria.

In an open randomized controlled trial, we compared one vial (10 mL) to two vials (20 mL) of EchiTAb-plus-ICP (EPI) antivenom among children with systemic carpet viper (Echis romani) envenoming of moderate severity in northeastern Nigeria. Systemic envenoming, presenting with incoagulable blood, was diagnosed using the 20-minute whole blood clotting test (20WBCT). Eligible patients with positive 20WBCT whose guardians assented were recruited and randomly allocated to receive either one vial or two vials of EPI administered either as a bolus or as a slow continuous infusion.

Comparison between the Smart Triage model and the Emergency Triage Assessment and Treatment guidelines in triaging children presenting to the emergency departments of two public hospitals in Kenya.

Several triage systems have been developed, but little is known about their performance in low-resource settings. Evaluating and comparing novel triage systems to existing triage scales provides essential information about their added value, reliability, safety, and effectiveness before adoption. This study included children aged < 15 years who presented to the emergency departments of two public hospitals in Kenya between February and December 2021.
