Zanzibar, a low-resource semiautonomous region of Tanzania, has an estimated prevalence of hepatitis B virus (HBV) infections of 3.6%. To assess the feasibility of care and treatment, a 5-year hepatitis B demonstration project was implemented in Zanzibar during January 2017-December 2021, following the 2015 WHO HBV care and treatment guidelines.

Pharmaco-Invasive Strategy With Half-Dose Tenecteplase in Patients With STEMI: Prespecified Pooled Analysis of Patients Aged ≥75 Years in STREAM-1 and 2.

Background: In STREAM-1 (Strategic Reperfusion Early After Myocardial Infarction), excess intracranial hemorrhage occurred in patients aged ≥75 years receiving full-dose tenecteplase as part of a pharmaco-invasive strategy, whereas no further intracranial hemorrhage occurred after halving the tenecteplase dose. In STREAM-2 (Second Strategic Reperfusion Early After Myocardial Infarction), half-dose tenecteplase was an effective and safe pharmaco-invasive strategy in older patients with ST-segment-elevation myocardial infarction presenting within <3 hours, compared with primary percutaneous coronary intervention (PCI). We prespecified evaluating the efficacy and safety of a half-dose versus full-dose pharmaco-invasive strategy and compared the half-dose pharmaco-invasive strategy to primary PCI in patients aged ≥75 years.

Community-associated methicillin-resistant in the Kimberley region of Western Australia, epidemiology and burden on hospitals.

This study presents surveillance data from 1 July 2003 to 30 June 2023 for community-associated methicillin-resistant (CA-MRSA) notified in the Kimberley region of Western Australia (WA) and describes the region's changing CA-MRSA epidemiology over this period. A subset of CA-MRSA notifications from 1 July 2003 to 30 June 2015 were linked to inpatient and emergency department records. Episodes of care (EOC) during which a positive CA-MRSA specimen was collected within the first 48 hours of admission and emergency presentations (EP) during which a positive CA-MRSA specimen was collected on the same day as presentation were selected and analysed further.

Projecting the benefit of vericiguat in PARADIGM-HF and DAPA-HF populations: Insights from the VICTORIA trial.

Aims: The VICTORIA trial demonstrated a significant reduction in the primary composite outcome of heart failure (HF) hospitalization or cardiovascular death with vericiguat relative to placebo in high-risk HF. This study aimed to contextualize treatment effects of vericiguat in populations with varying risk profiles simulated from the PARADIGM-HF and DAPA-HF trials.

Methods: Subgroups of VICTORIA participants (n = 5050) were generated to simulate PARADIGM-HF and DAPA-HF trial populations.

Evaluation of Hepatitis C Virus Transmission Through Endoscopy Procedures in the Country of Georgia.

Exposure to healthcare procedures might be a source of hepatitis C virus (HCV) transmission in Georgia, one of the few countries currently on track to eliminate hepatitis C. While there has been a history of iatrogenic transmission of HCV, the risk of HCV transmission related to endoscopic procedures has not been previously assessed in Georgia. The goal of this study was to assess HCV seroconversion among individuals undergoing endoscopic procedures to estimate the relative role and incidence of HCV infection attributable to endoscopic procedures.

Evaluation of Knowledge, Attitudes and Practices for Hepatitis B Virus Infection Among Primary Healthcare Physicians in Georgia.

A nationwide serosurvey among adults in 2021 showed a 2.7% (95% confidence interval [CI]: 2.3%-3.

Expanding the solvent diversity and perovskite compatibility of SnO inks that are directly deposited on perovskite layers.

Tin oxide (SnO) is an attractive electron transport material (ETM) for perovskite solar cells (PSCs) due to its optoelectronic properties, low-temperature solution processability, cost, and stability. However, solvent incompatibilities have largely limited its application to devices with SnO deposited below the perovskite. To expand its utility in other device structures, including inverted PSCs and tandem devices, alternate deposition strategies are needed.

An evolutionarily conserved function of C-reactive protein is to prevent the formation of amyloid fibrils.

C-reactive protein (CRP) binds to phosphocholine (PCh)-containing substances and subsequently activates the complement system to eliminate the ligand. The PCh-binding function of CRP has been conserved throughout evolution from arthropods to humans. Human CRP, in its structurally altered conformation at acidic pH, also binds to amyloid-β (Aβ) and prevents the formation of Aβ fibrils.

Hepatitis C virus attributable liver cancer in the country of Georgia, 2015-2019: a case-control study.

Background: Hepatitis C virus (HCV) infection can lead to a type of primary liver cancer called hepatocellular carcinoma (HCC). Georgia, a high HCV prevalence country, started an HCV elimination program in 2015. In addition to tracking incidence and mortality, surveillance for the HCV-attributable fraction of HCC is an important indicator of the program's impact.

Multiparameter phenotyping of platelets and characterization of the effects of agonists using machine learning.

Background: Platelet function is driven by the expression of specialized surface markers. The concept of distinct circulating subpopulations of platelets has emerged in recent years, but their exact nature remains debatable.

Objectives: To design a spectral flow cytometry-based phenotyping workflow to provide a more comprehensive characterization, at a global and individual level, of surface markers in resting and activated healthy platelets, and to apply this workflow to investigate how responses differ according to platelet age.

Proteomics Identify Clinical Phenotypes and Predict Functional Outcomes in Heart Failure With Preserved Ejection Fraction: Insights From VITALITY-HFpEF.

Background: Heart failure with preserved ejection fraction (HFpEF) is a heterogeneous syndrome that may emerge from overlapping systemic processes associated with comorbidities. We assessed whether unique clusters of circulating proteins are associated with specific clinical characteristics and functional status at baseline and follow-up in a well-phenotyped cohort of patients with HFpEF.

Methods: We evaluated 368 proteins associated with cardiovascular disease and inflammation in prerandomization blood samples from 763 VITALITY-HFpEF (Vericiguat to Improve Physical Functioning in Daily Living Activities of Patients With HFpEF) participants who had a left ventricular ejection fraction ≥45% and a heart failure decompensation event within 6 months.

Unexpected spontaneous expectoration of a grass bur: A case report.

Adult foreign body aspiration is rare and represents only 15%-25% of all foreign body aspirations and 1 in 400 bronchoscopy procedures. Typically, adults present non-emergently and exhibit non-specific symptoms, which makes the diagnosis of foreign body aspiration especially difficult when a history of aspiration cannot be elicited. We present a 63-year-old male with a past medical history of chronic obstructive pulmonary disease hospitalized for left thoracic empyema caused by the aspiration of a grass bur.

Comparing Analytical Methods for Composite End Points in Clinical Trials: Insights from the Vericiguat Global Study in Subjects with Heart Failure With Reduced Ejection Fraction Trial.

Background: In VICTORIA (Vericiguat Global Study in Subjects with Heart Failure with Reduced Ejection Fraction), participants with heart failure (HF) and reduced ejection fraction, vericiguat decreased the primary composite outcome (time to first HF hospitalization [HFH] or cardiovascular death [CVD]) (897 events) compared with placebo (972 events) (hazard ratio, 0.90; 95% confidence interval [CI], 0.82-0.

Biomarker profiles associated with reverse ventricular remodelling in patients with heart failure and a reduced ejection fraction: Insights from the echocardiographic substudy of the VICTORIA trial.

Aims: Reverse ventricular remodelling, defined as a decrease in left ventricular end-systolic volume indexed to body surface area (LVESVI) or an increase in left ventricular ejection fraction (LVEF), is associated with improved clinical outcomes in patients with heart failure with reduced ejection fraction (HFrEF). However, the underlying pathophysiological mechanisms remain unclear.

Methods And Results: We evaluated paired core-lab assessed echocardiograms and measurements of 92 biomarkers at baseline and 8 months thereafter in 419 participants with HFrEF.

Identification and Candidate Gene Evaluation of a Large Fast Neutron-Induced Deletion Associated with a High-Oil Phenotype in Soybean Seeds.

Since the dawn of agriculture, crops have been genetically altered for desirable characteristics. This has included the selection of natural and induced mutants. Increasing the production of plant oils such as soybean () oil as a renewable resource for food and fuel is valuable.

Modelling the potential impact of global hepatitis B vaccination on the burden of chronic hepatitis B in the United States.

About 80% of persons with chronic hepatitis B virus (HBV) infection in the United States are non-US-born. Despite improvements in infant hepatitis B vaccination globally since 2000, work remains to attain the World Health Organization's (WHO) global 2030 goal of 90% vaccination. We explore the impacts on the United States of global progress in hepatitis B vaccination since 2000 and of achieving WHO hepatitis B vaccination goals.

Bicarbonate and Serum Lab Markers as Predictors of Mortality in the Trauma Patient.

Introduction: Severe trauma-induced blood loss can lead to metabolic acidosis, shock, and death. Identification of abnormalities in the bicarbonate and serum markers may be seen before frank changes in vital signs in the hemorrhaging trauma patient, allowing for earlier lifesaving interventions. In this study the author aimed to evaluate the usefulness of serum bicarbonate and other lab markers as predictors of mortality in trauma patients within 30 days after injury.
