Hypertension, a key modifiable risk factor for cardiovascular diseases (CVD), significantly contributes to premature death and morbidity worldwide. Despite stabilization in age-adjusted global prevalence, the absolute number of hypertensive individuals doubled from 2000 to 2010, largely due to increases in low- and middle-income countries. In 2021, only 21% of hypertensive individuals globally had effective blood pressure (BP) control.

Background: Households are considered ideal settings for studying the transmission dynamics of an infectious disease.

Methods: A prospective study was conducted, based on the World Health Organization FFX protocol from October 2020 to January,2021. Household contacts of laboratory-confirmed index cases were followed up for their symptomatic history, nasal swabs for RT-PCR,and blood samples for anti-SARS CoV-2 antibodies were collected at enrollment and days 7, 14 and 28.

Objective: To determine population-based estimates of coronavirus disease 2019 (COVID-19) in a densely populated urban community of Karachi, Pakistan.

Methods: Three cross-sectional surveys were conducted in April, June and August 2020 in low- and high-transmission neighbourhoods. Participants were selected at random to provide blood for Elecsys immunoassay for detection of anti-severe acute respiratory syndrome coronavirus-2 antibodies.

Background: Hearing loss/deafness is a common otological disorder found in the Pakistani population due to the high prevalence of consanguineous unions, but the full range of genetic causes is still unknown.

Methods: A large consanguineous Pakistani kindred with hearing loss was studied. Whole-exome sequencing and Sanger sequencing were performed to search for the candidate gene underlying the disease phenotype.

Background: Reactive oxygen species are involved in the etiology and progress of many kinds of diseases such as cancer, cardiovascular diseases, inflammatory and neurodegenerative disorders. Epidemiological studies reported that fruits, vegetables, and wines containing a high percentage of phenolics and flavonoids showed a positive impact in treating inflammatory diseases, reducing cancer risk, and increasing life expectancy.

Objective: Some Mongolian medicinal plants were studied for their antioxidant activity and anticancer effects.

We aimed to detect the causative gene in five unrelated families with recessive inheritance pattern neurological disorders involving the central nervous system, and the potential function of the NEMF gene in the central nervous system. Exome sequencing (ES) was applied to all families and linkage analysis was performed on family 1. A minigene assay was used to validate the splicing effect of the relevant discovered variants.

Background Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) has spread to almost every country on the globe, and each country is reporting the symptomatic presentation of their patients to give better insight into the various clinical presentations of SARS-CoV-2. However, the epidemiological literature from Pakistan is scanty. Methods We retrospectively analyzed data from 412 patients who were residents of East Karachi and tested positive for SARS-CoV-2 between February 26 to April 24, 2020.
