The prevalence of undiagnosed attention-deficit/hyperactivity disorder among undergraduate medical students: a survey from Pakistan.

Background: Attention-deficit/hyperactivity disorder (ADHD) is now acknowledged as a significant public health concern, a persistent neurodevelopmental disorder. It poses challenges across various life domains, persisting into adulthood, and is often undiagnosed. From July 2023 to December 2023, this study investigated the prevalence, types, participants' knowledge and perceptions, and demographic determinants of undiagnosed adult ADHD among undergraduate medical students in Pakistan.

Coronary embolism and acute limb ischemia without pre-existing atrial fibrillation: Hunt for the hidden thrombus.

Coronary embolism (CE) is an infrequent etiology of myocardial infarction secondary to embolization of occlusive thrombi within the coronary arteries, typically arising in patients with pre-existing atrial fibrillation. Clinical presentation is similar to atherosclerotic myocardial infarction, however the condition is likely underrecognized. The simultaneous presence of other embolic manifestations may assist with diagnosis, although definitive therapy, medical or interventional, remains inconclusive.

Comparison between mono vs dual vs triple antiplatelet therapy in patients with ischemic heart disease undergoing PCI, a network meta-analysis.

Aims: We aim to research the efficacy and safety of single(SAPT), dual(DAPT), and triple(TAPT) antiplatelets approaches across IHD patients undergoing PCI.

Methods And Results: A network meta-analysis was conducted until April 1st, 2024, using the netmeta package in R studio 4.3.

Perils of reduced dose apixaban in atrial fibrillation/flutter - A case report with a brief literature review.

Patients with atrial fibrillation/atrial flutter (AF) are notoriously predisposed to thromboembolic events secondary to the development of thrombi within the left atrium of the heart. AF accompanied by a fairly decent CHA2DS2-VASc score is a known indication for full anticoagulation, frequently with direct oral anticoagulants (DOACs), such as apixaban. Following extensive studies weighing the benefits of anticoagulation versus risks of major bleeding, patients meeting two or more of the dose-reduction criteria (age ≥80 years, weight ≤60 kg, and/or creatinine ≥ 1.

The variable domain from dynamin-related protein 1 promotes liquid-liquid phase separation that enhances its interaction with cardiolipin-containing membranes.

Dynamins are an essential superfamily of mechanoenzymes that remodel membranes and often contain a "variable domain" important for regulation. For the mitochondrial fission dynamin, dynamin-related protein 1, a regulatory role for the variable domain (VD) is demonstrated by gain- and loss-of-function mutations, yet the basis for this is unclear. Here, the isolated VD is shown to be intrinsically disordered and undergo a cooperative transition in the stabilizing osmolyte trimethylamine N-oxide.

Glue embolization to the lung vasculature following histoacryl injection sclerotherapy: A neglected etiology of pulmonary embolism.

Pulmonary embolism is a significant complication of N-butyl-2-cyanoacrylate, commonly known as histoacryl, used to sclerose bleeding gastroesophageal varices. We present a 50-year-old female with seronegative chronic liver disease who was managed with endoscopic histoacryl injection sclerotherapy for bleeding gastric fundal varices. Following treatment, the patient developed sudden respiratory distress due to multiple pulmonary glue emboli, requiring inpatient supportive care along with close monitoring for a week.

Public Knowledge About COVID-19 Booster Vaccines in Pakistan: A Study Conducted in a Tertiary Care Hospital in Karachi.

The coronavirus disease 2019 (COVID-19) pandemic has deteriorated the healthcare system and economy worldwide. Globally, by making the primary vaccination against the coronavirus necessary, the surge in cases waned, but as the effects of this vaccination decreased after some time, to prevent another pandemic, vaccination was still necessary. As a result, receiving a COVID-19 booster shot can boost immunity against the coronavirus.

The variable domain from the mitochondrial fission mechanoenzyme Drp1 promotes liquid-liquid phase separation.

Dynamins are an essential superfamily of mechanoenzymes that remodel membranes and often contain a "variable domain" (VD) important for regulation. For the mitochondrial fission dynamin, Drp1, a regulatory role for the VD is demonstrated by mutations that can elongate, or fragment, mitochondria. How the VD encodes inhibitory and stimulatory activity is unclear.

Endovascular coil embolization of ruptured and unruptured intracranial aneurysms: review of a 15 year single center experience in Pakistan.

Objective: To assess the outcome of endovascular treatment of intracranial aneurysm over 15 years.

Methods: The retrospective study was conducted at the at Radiology Department of Aga Khan University Hospital, Karachi, and comprised medical records from April 2003 to April 2018 of patients who received endovascular treatment for intracranial aneurysm. Multiple variables reviewed included demographics, clinical presentation, aneurysm morphology, technique used, technique outcome and clinical outcome.

The Gene Expression Deconvolution Interactive Tool (GEDIT): accurate cell type quantification from gene expression data.

Background: The cell type composition of heterogeneous tissue samples can be a critical variable in both clinical and laboratory settings. However, current experimental methods of cell type quantification (e.g.

Acute Kidney Injury after Congenital Heart Disease Surgery: A Single-Center Experience in a Low- to Middle-Income Country.

Background Acute kidney injury (AKI) is a commonly recognized clinical problem after congenital heart disease (CHD) surgery. Increased perioperative morbidity, development of chronic kidney disease, and increased mortality are the major concerns. We investigated frequency, risk factors, and outcomes of AKI after CHD surgery at our hospital.

Angiography and Therapeutic Embolisation of Bleeding Aberrant Iliac Artery Branches.

A 78-year female presented with the complain of per rectal fresh bleeding for 4 days. She was known to have diabetes and hypertension, 3 weeks back. She had an episode of left middle cerebral artery (MCA) stroke.

Neuroimaging Findings in Tuberculosis: A Single-Center Experience in 559 Cases.

Background And Purpose: There is a paucity of literature related to the neuroimaging of CNS tuberculosis (TB) and largely covers pediatric CNS TB. The objective of this study was to determine the frequency of different forms of CNS TB and its associated complications and to study longitudinal disease course using computed tomography (CT) and MRI.

Methods: Retrospective chart and imaging review of patients diagnosed with CNS TB in a tertiary care hospital in Pakistan over a 10-year period.

Susceptibility profile of methicillin-resistant to linezolid in clinical isolates.

Objective: To determine the resistance and sensitivity pattern of methicillin-resistant Staphylococcus aureus (MRSA) isolates to linezolid (LZD) along with its prevalence in a tertiary care hospital of Karachi, Pakistan.

Materials And Methods: A cross-sectional study was carried out. This study lasted for about 1 year.
