Objective: This study aimed to explore the perceptions of frontline Healthcare Workers (HCWs) towards managing COVID-19 in Tertiary care hospital in Pakistan.

Method: This qualitative exploratory study was conducted from January to May 2021 at a Tertiary care hospital designated for COVID-19 patients in Rawalpindi Pakistan. Semi-structured in-depth interviews were conducted from twenty six HCWs.

Efficacy of Nicorandil in Preventing Myocardial Injury and Cardiovascular Outcomes in Patients Undergoing Percutaneous Coronary Intervention (PCI): A Systematic Review and Meta-Analysis.

Percutaneous coronary intervention (PCI) is a common procedure for treating coronary artery disease, but it carries a risk of periprocedural myocardial injury (PMI). This meta-analysis evaluated the efficacy of nicorandil, a hybrid compound with nitrate-like and potassium channel-opening properties, in preventing PMI during PCI. A comprehensive literature search identified 14 studies involving 1,762 patients, with 882 receiving nicorandil and 880 in the control group.

Effectiveness of silver diamine fluoride (SDF) in arresting coronal dental caries in children and adolescents: a systematic review.

Dental caries remains a significant public health issue for children globally, leading to adverse effects on health and development. Silver diamine fluoride (SDF) is a potential preventive agent that can prevent caries progression in children. This systematic review examined the effectiveness of silver diamine fluoride in arresting caries compared to other fluorides.

Composite Ensemble Learning Framework for Passive Drone Radio Frequency Fingerprinting in Sixth-Generation Networks.

The rapid evolution of drone technology has introduced unprecedented challenges in security, particularly concerning the threat of unconventional drone and swarm attacks. In order to deal with threats, drones need to be classified by intercepting their Radio Frequency (RF) signals. With the arrival of Sixth Generation (6G) networks, it is required to develop sophisticated methods to properly categorize drone signals in order to achieve optimal resource sharing, high-security levels, and mobility management.

An analysis of 105 female-perpetrated mass murders.

Most research on mass murderers to date has focused on perpetrators of male sex, while research on perpetrators of female sex has been relegated to case reports and series. We aimed to more fully examine the phenomenon of female-perpetrated mass murder. We analyzed 1715 worldwide incidents of personal-cause mass murder from 1900 to 2019, identifying 105 (6%) events perpetrated by females.

Positive Airway Pressure, Mortality, and Cardiovascular Risk in Older Adults With Sleep Apnea.

Importance: Positive airway pressure (PAP) is the first-line treatment for obstructive sleep apnea (OSA), but evidence on its beneficial effect on major adverse cardiovascular events (MACE) and mortality prevention is limited.

Objective: To determine whether PAP initiation and utilization are associated with lower mortality and incidence of MACE among older adults with OSA living in the central US.

Design, Setting, And Participants: This retrospective clinical cohort study included Medicare beneficiaries with 2 or more distinct OSA claims identified from multistate, statewide, multiyear (2011-2020) Medicare fee-for-service claims data.

Exploring stakeholder perceptions of implementing a pharmacist-led anticoagulation clinic in primary care settings: a cross-sectional study.

Background: Anticoagulation therapy is crucial for managing various cardiovascular and thrombotic conditions; however, optimal delivery remains challenging in primary care. Pharmacist-led anticoagulation services have emerged as a potential strategy for enhancing patient care and outcomes in such settings. Understanding the perspectives of key stakeholders is critical for successful implementation.

Off-pump vs. on-pump coronary artery bypass grafting in patients with chronic kidney disease: an updated systematic review and meta-analysis.

Background: In patients with chronic kidney disease (CKD), cardiovascular disease is found to be the primary cause of mortality, and after coronary artery bypass grafting (CABG), their prognosis deteriorates.

Methods: We conducted a meta-analysis comparing off-pump CABG versus on-pump CABG in CKD patients. We searched electronic databases, including PubMed, Cochrane, and Google Scholar, using relevant keywords.

Synthesis and bioactivity of a novel surfactin-based lipopeptide for mRNA delivery.

The effective delivery of messenger ribonucleic acid (mRNA) to specific cell types and target tissues poses a significant challenge in nonviral therapeutic strategies. Lipid-based nanoparticles (LNPs) have emerged as a leading carrier system for delivering mRNA, particularly for infectious diseases, such as COVID-19. This study aimed to describe the synthesis of a novel lipopeptide based on surfactin, a naturally occurring surfactant.

Glioblastoma: Overview and Magnetic Resonance Spectroscopy Analysis for Treatment.

Glioblastoma multiforme (GBM) is a very aggressive and fast-growing cancer of the brain that has a low life expectancy. Many new cases are diagnosed every year with each having a very poor prognosis. It is therefore of utmost concern to develop cures for such a devastating condition.

Risk Factors Associated With Anastomotic Stricture in Patients Undergoing Minimally Invasive Esophagectomy: Experience From a High-Volume Center.

Background: Esophageal cancer is a prevalent cancer, with a high incidence in low socioeconomic category countries. Minimally invasive esophagectomy is increasingly being used to treat this malignant condition. However, anastomotic stricture is a serious complication post esophagectomy.

Haemato-radiology: the role of the radiologist at MDT.

Haemato-radiology represents a relatively newly emerging, vast, and complex area of diagnostic imaging. Its complexity arises from the multimodality nature of patient assessment, the multisystem presentation of haematological malignancies and their complications, and the volume of imaging required for diagnosis and follow-up of the fifth most common malignancy type in the United Kingdom. Decisive and accurate assessment of disease by radiologists is at the heart of the haemato-oncology multidisciplinary team (MDT) and therefore essential for providing optimal patient care.

DFT and comparative adsorption study of NiO, MnO, and MnNiO nanomaterials for the removal of amaranth dye from synthetic water.

In the current study, NiO nanoparticles, MnO nanoparticles, and MnNiO nanocomposites (Ni-NPs, Mn-NPs and MN-NCs, respectively) were synthesized using a facile hydrothermal method, and their performance in the removal of amaranth (AM) dye from synthetic wastewater was compared. XRD, FTIR spectroscopy, SEM, BET analysis, and TGA were performed to characterize the produced catalysts. The effect of pertinent parameters, including pH, dosage of catalysts, temperature, and shaking speed on the uptake of AM was investigated through batch experiments.

Regulation of proteostasis by sleep through autophagy in models of Alzheimer's disease.

Sleep and circadian rhythm dysfunctions are common clinical features of Alzheimer's disease (AD). Increasing evidence suggests that in addition to being a symptom, sleep disturbances can also drive the progression of neurodegeneration. Protein aggregation is a pathological hallmark of AD; however, the molecular pathways behind how sleep affects protein homeostasis remain elusive.

Prospective exploratory evaluation of Cepheid Xpert Mycobacterium tuberculosis host response cartridge: a focus on adolescents and young adults.

Background: An accurate, rapid, non-sputum-based triage test for diagnosing tuberculosis (TB) is needed.

Methods: A prospective evaluation of the Xpert-MTB-HR cartridge, a prototype blood-based host-response mRNA signature assay, among individuals presenting with TB-like symptoms was performed in Pakistan and results were compared to three reference standards: Xpert MTB/RIF Ultra, bacteriological confirmation (Xpert MTB/RIF Ultra and/or culture positivity), and composite clinical diagnosis (clinician diagnosis, treatment initiation, Xpert MTB/RIF Ultra, and/or culture positivity). Analyses were conducted both for the entire study cohort and separately in the adolescent and young adult cohort (ages 10-24).
