Objective: To determine the frequency of factor V leiden mutation.
Design: Observational study.
Place And Duration Of Study: One-year, January 2001 to December 2001 at the Armed Forces Institute of Pathology, Rawalpindi, Pakistan.
Patients And Methods: Two hundred subjects each of apparently healthy and unrelated Punjabi and Pathan origins were included in the study. Peripheral blood samples were collected in EDTA and DNA extracted by phenol-chloroform extraction method. DNA analysis was done by PCR for restriction fragment length polymorphism. The product was digested overnight with Mn/1 and electrophoresed on acrylamide gel to detect 67 and 153 base pair fragments of factor V leiden against 37, 67 and 116 base pair fragments of normal factor V.
Results: In the 400 subjects studied, only 5 cases of heterozygotes for factor V leiden were detected. The overall carrier rate was 1.3% (95% Cl 0.2-2.2%). The carrier rate in Punjabis and Pathans was 1% and 1.5% respectively.
Conclusion: This study confirms that the prevalence of factor V leiden is low in Asians and Africans as compared to the European population.

Importance: How epilepsy may promote cardiovascular disease remains poorly understood.
Objective: To estimate the odds of new-onset cardiovascular events (CVEs) over 6 years in older people with vs without epilepsy, exploring how enzyme-inducing antiseizure medications (EIASMs) and traditional cardiovascular risk factors mediate these odds.
Design, Setting, And Participants: This was a prospective cohort study using the comprehensive cohort of the Canadian Longitudinal Study on Aging (CLSA), with 6 years of follow-up (2015-2021, analysis performed in December 2023).

Objective: Temporal lobe epilepsy with hippocampal sclerosis (HS) is a surgically remediable syndrome. We determined temporal trends in the prevalence of hippocampal sclerosis surgeries and related factors.
Methods: We analysed a prospective cohort of adults who underwent epilepsy surgery at the NHNN, London, between 1990 and 2019.

Background: Conventional tests for inherited thrombophilia focus on the five most-established inherited thrombophilias; i.e. deficiencies in antithrombin, protein C, and protein S, and the factor V Leiden and prothrombin G20210A variants.

Axial spondyloarthritis manifests as a chronic inflammatory disease primarily affecting the sacroiliac joints and spine. Although chronic back pain and spinal stiffness are typical initial symptoms, peripheral (ie, enthesitis, arthritis, and dactylitis) and extra-musculoskeletal (ie, uveitis, inflammatory bowel disease, and psoriasis) manifestations are also common. Timely and accurate diagnosis is challenging and relies on identifying a clinical pattern with a combination of clinical, laboratory (HLA-B27 positivity), and imaging findings (eg, structural damage on pelvic radiographs and bone marrow oedema on MRI of the sacroiliac joints).

Prophages constitute a substantial portion of bacterial genomes, yet their effects on hosts remain poorly understood. We examine the abundance, distribution, and activity of prophages in Bacillus subtilis using computational and laboratory analyses. Genome sequences from the NCBI database and riverbank soil isolates reveal prophages primarily related to mobile genetic elements in laboratory strains.
