Management of possible serious bacterial infections in young infants where referral is not possible in the context of existing health system structure in Mbeya, Tanzania: Experience and lessons from the end line assessment.

Severe bacterial infections (SBIs) are a leading cause of neonatal deaths in low- and middle-income countries. World Health Organization's (WHO's) guideline for outpatient management of danger signs indicating possible serious bacterial infections (PSBI) when referral is not possible was adopted by three pilot district councils in Mbeya Region, in Tanzania (Busekelo, Kyela and Mbarali Districts) in 2018 (the PSBI project). This study documented changes in practice during the PSBI project, and lessons learned.

An electroporation cytometry system for long-term, live cell cycle analysis.

Electric fields are used in biology to address a broad range of questions and through a variety of techniques, including electroporation, gene electrotransfer (GET), electrostimulation (ES), and electrochemotherapy. Each of these modalities requires specific conditions and has drastically different target outcomes on the cell. ES has demonstrated that non-pore forming electric fields alter cell cycle progression.

Long term measurements of aerosol mass concentration with optical particle counters: Discrepancies with plausible reasons.

Gravimetry-based direct measurements of mass concentration require offline analysis which is not suited for field campaigns. Hence such campaigns rely on the estimation of mass concentration by indirect methods mostly calibrated in controlled laboratory conditions. Optical particle counter (OPC) employs algorithms converting the measured number concentration to mass concentration using appropriate conversion factors.

Unveiling potential inhibitors targeting the nucleocapsid protein of SARS-CoV-2: Structural insights into their binding sites.

The Nucleocapsid (N) protein of SARS-CoV-2 plays a crucial role in viral replication and pathogenesis, making it an attractive target for developing antiviral therapeutics. In this study, we used differential scanning fluorimetry to establish a high-throughput screening method for identifying high-affinity ligands of N-terminal domain of the N protein (N-NTD). We screened an FDA-approved drug library of 1813 compounds and identified 102 compounds interacting with N-NTD.

Quantifying health facility service readiness for small and sick newborn care: comparing standards-based and WHO level-2 + scoring for 64 hospitals implementing with NEST360 in Kenya, Malawi, Nigeria, and Tanzania.

Background: Service readiness tools are important for assessing hospital capacity to provide quality small and sick newborn care (SSNC). Lack of summary scoring approaches for SSNC service readiness means we are unable to track national targets such as the Every Newborn Action Plan targets.

Methods: A health facility assessment (HFA) tool was co-designed by Newborn Essential Solutions and Technologies (NEST360) and UNICEF with four African governments.

Health facility assessment of small and sick newborn care in low- and middle-income countries: systematic tool development and operationalisation with NEST360 and UNICEF.

Synthesis and Evaluation of Ivacaftor Derivatives with Reduced Lipophilicity.

Mutations in the unique ATP-binding cassette anion channel, the cystic fibrosis conductance regulator (CFTR), lead to the inherited fatal disease known as cystic fibrosis (CF). Ivacaftor enhances channel gating of CFTR by stabilizing its open state and has been approved as monotherapy for CF patients with CFTR gating mutations (e.g.

Proximity Mapping of Ciliary Proteins by BioID.

The primary cilium is a highly conserved microtubule-based organelle present in most vertebrate cell types. Mutations in ciliary protein genes can lead to dysfunctional or absent cilia and are the cause of a large group of heterogeneous diseases known as ciliopathies. ARL13B is a member of the ARF family of regulatory GTPases and is highly enriched on the ciliary membrane.

A Proteomic Survey of the Cystic Fibrosis Transmembrane Conductance Regulator Surfaceome.

The aim of this review article is to collate recent contributions of proteomic studies to cystic fibrosis transmembrane conductance regulator (CFTR) biology. We summarize advances from these studies and create an accessible resource for future CFTR proteomic efforts. We focus our attention on the CFTR interaction network at the cell surface, thus generating a CFTR 'surfaceome'.

Structural characterization of transcription-coupled repair protein UVSSA and its interaction with TFIIH protein.

UV-stimulated scaffold protein A (UVSSA) is a key protein in the Transcription-Coupled Nucleotide Excision Repair (TC-NER) pathway. UVSSA, an intrinsically disordered protein, interacts with multiple members of the pathway, tethering them into the complex. Several studies have reported that UVSSA recruits Transcription Factor IIH (TFIIH) via direct interaction, following which CSB is degraded and the lesion recognition TC-NER complex dissociates from the damage site to facilitate the DNA repair.

Hospitalization Outcomes of Acute Pancreatitis in Hematopoietic Stem Cell Transplant Recipients.

Background: Acute pancreatitis (AP) carries a significant morbidity and mortality worldwide. AP is a potential complication of hematopoietic stem cell transplantation (HSCT) although its incidence remains unclear. HSCT recipients are at increased risk of AP due to various factors but the effect of AP on mortality and resource utilization in the adult population has not been studied.

Implementation of distance learning IMCI training in rural districts of Tanzania.

Background: The standard face-to-face training for the integrated management of childhood illness (IMCI) continues to be plagued by concerns of low coverage of trainees, the prolonged absence of trainees from the health facility to attend training and the high cost of training. Consequently, the distance learning IMCI training model is increasingly being promoted to address some of these challenges in resource-limited settings. This paper examines participants' accounts of the paper-based IMCI distance learning training programme in three district councils in Mbeya region, Tanzania.

Effect of Hospital Teaching Status on Outcomes of Patients With Acute Pancreatitis.

Introduction Multiple studies have shown that outcomes of various diseases differ by the hospital teaching status. However, not much is known about the effects of hospital teaching status on outcomes of acute pancreatitis (AP). The aim of this study was to identify if there was an effect of hospital teaching status on the outcomes of AP.

Hospital frailty risk score predicts worse outcomes in patients with chronic pancreatitis.

Background: Chronic pancreatitis (CP) is a pathological fibroinflammatory response to persistent inflammation or stress to the pancreas. The effect of frailty on outcomes in patients with CP has not been previously examined. In this study, we examined the effect of frailty on outcomes in hospitalized patients with CP.

Predictors of leaving against medical advice in patients with alcohol-related hepatitis.

Background: Alcohol-related hepatitis is one of the most severe manifestations of alcohol-related liver disease and has been associated with significant morbidity, mortality and financial burden. Patients with alcohol use disorders are at risk of leaving against medical advice (LAMA); however, there is currently a lack of data in the literature to show which patients are at higher risk. In this study, we investigated the specific demographic factors and comorbidities associated with LAMA.

Seasonal Variations of Hospital Admissions for Alcohol-Related Hepatitis in the United States.

Background: Clinical experience suggests an increased hospitalization rate for alcohol-related hepatitis (AH) in the winter months; however, seasonal variations in the prevalence of hospitalizations for AH have not been described previously. We hypothesized that AH hospitalizations would be higher in the winter months due to the holiday season and increased alcohol sales.

Methods: Patients with primary or secondary discharge diagnosis of AH were included in the study (International Classification of Diseases, Clinical Modification-10th Revision codes K70.

Clusters of COVID-19 Indicators in India: Characterization, Correspondence and Change Analysis.

We conduct a long-term epidemiology study of COVID-19 in India from Mar 2020 to May 2021 using a number of indicators such as active cases, daily new cases, and deaths, on a micro (district level, per capita) and macro level (state level). Our automated shape-based cluster discovery of the per capita daily new cases () during the in India (between Mar 2020 and Jan 2021) revealed four distinct shape patterns: sharp-rise and decline, steady-rise and decline, plateau and multiple relatively high peaks. These clusters exhibit a strong geographical correlation.
