Recruitment of adequate number of healthy volunteers is vital for success of clinical trials but there is limited research on factors motivating the healthy volunteers to participate in clinical trials especially in developing countries. Pakistani researchers also faced the problems in enrollment of enough healthy volunteers during COVID-19 pandemic when a number of clinical trials began in Pakistan. Around 117 research proposals were processed by the National Bioethics Committee (NBC) of Pakistan in last two years. A major proportion of these clinical research studies target healthy populations as primary research subjects or as controls. Numerous studies have investigated factors such as motives, barriers, risks. benefits and ethical values affecting recruitment and participation of healthy volunteers in clinical trials. We have reviewed the literature to learn about factors that motivate or prevent the healthy persons to volunteer along with the pertaining ethical issues. Financial incentive is the principal motive for healthy... Continue Reading

Background and Objective: Dengue fever (DF) has been a major health concern globally. Pakistan is also combating this infection for the last decade. Cytokine genes play an important role in DF pathogenesis. This study aimed to analyze dendritic cell-specific intercellular adhesion molecule-3-grabbing non-integrin (DC-SIGN) and tumor necrosis factor α (TNF-α) genes promoter polymorphisms in DF patients. Methods: A total of 140 (n = 140) dDF patients were recruited for study at the Department of Human Genetics and Molecular Biology of University of Health Sciences, Lahore, Pakistan over a period of 3 years. Simple DF was noted in 105 patients (75%) while 35 (25%) showed bleeding complications. All patients were found positive for dengue non-structural protein or dengue IgM. All patients were tested for two polymorphisms in TNF-α (-238G/A, and -308G/A) and one polymorphism in DC-SIGN (-336G/A) using restriction fragment length polymorphism technique. A single nucleotide polymorphism stats program was used... Continue Reading

ABSTRACT Background and Objective: A global increase in the prevalence of diabetes mellitus (DM) is associated with increased morbidity and mortality. Oxidative stress is a fundamental component in the pathogenesis of DM Ajwa dates are known to have a high antioxidant content, especially in their seeds. Hence this study was designed to determine the preventive effects of Ajwa date fruit on alloxan-induced diabetes in an experimental rat model. Methods: This experimental study was conducted at the Post Graduate Medical Institute, Lahore, Pakistan. A total of forty Sprague-Dawley rats were divided into five groups with eight animals in each. Rats in group A were normal control, whereas rats in group B were induced with intraperitoneal alloxan (160 mg/kg body weight) to develop diabetes. Groups C, D, and E rats were fed on a diet supplemented with Ajwa flesh, seed, and whole Ajwa respectively for 1 week. Blood and urine glucose levels... Continue Reading

Background and Objective: Plastic surgeons face challenging conditions when dealing with soft tissue injuries or defects involving the lower part of the leg and the proximal part of the foot. The objective of the current study is to compare single-staged reverse sural artery flaps with two-staged interpolated flaps in distal lower limb injuries. Methods: It was a prospective study carried out at the Department of Plastic Surgery, Allama Iqbal Memorial Teaching Hospital, Sialkot, Pakistan, over 5 years from 2015 to 2020. Sixty-eight (n = 68) patients with distal lower limb soft-tissue defects were enrolled and randomly allotted a two-stage interpolated flap design (group A) or single-stage reverse sural artery flap design (group B). The measured outcomes included the frequency of flap-tip necrosis, epidermolysis, partial or total flap loss, and additional procedures needed for managing these complications. Results: Out of all the patients, 72% were of male gender and 28% were... Continue Reading

Background and Objectives: Poliomyelitis still remains a significant public health concern in developing countries though it has been eradicated from most of the world. Illiteracy, cultural constraints, and skepticism of the general public regarding vaccination are considered major impediments to its successful eradication from developing countries. In this study, the authors aimed to evaluate parental knowledge and attitudes about poliomyelitis and its immunization in a local population as well as to elucidate the determinants and barriers relating to the immunization process. Methods: This mixed-method study was conducted on 350 consenting parents who accompanied their children under 5 years of age at the pediatric outdoors of a tertiary care hospital in Sialkot, Pakistan. Parents of only those children were included for the study who had failed to receive a polio dose during the last two supplementary immunization activities The parents were interviewed on a pre-tested, semi structured questionnaire. Statistical Package for... Continue Reading

Background and Objective: The contagious and invasive nature has made coronavirus disease-19 (COVID-19) a critical health issue for the community. The lower respiratory tract is the major site of inflammation seen in COVID-19-positive individuals. Vitamin D (Vit D) has been proposed to have a positive role in immunomodulation, hence, this study aimed to determine the association between Vit D levels and the severity of COVID-19 in infected pediatric patients presenting at a secondary healthcare hospital in Pakistan. Methods: This cross-sectional analytical study was conducted on 100 pediatric patients of the age range 1-18 years from March to December 2021. These patients were hospitalized and diagnosed with coronavirus disease with confirmed results on a real‐time reverse transcription-polymerase chain reaction. Blood samples of the patients were taken to monitor the baseline levels of markers of acute infection and Vit D levels. Patients with serum Vit D levels ≤ 20ng/ml were labeled with...

Background and Objective: Manual therapy is a treatment approach by physical therapists where different techniques are applied to patients with hands for rehabilitation purposes. The objective of the study was to find the frequency of De’Quervain tenosynovitis and thumb and wrist pain in physical therapists working in different rehabilitation centers in relation to age, body mass index (BMI), and working hours. Methods: A cross-sectional study was conducted on 135 physical therapists working in different settings in Lahore, Pakistan. Physiotherapists were enrolled by convenience sampling. Data were recorded on a questionnaire form. Finkelstein test was performed to check De Quervain’s tenosynovitis. A numeric pain rating scale was sued to measure pain. The data were tested for significance using statistical tests. Results: On the dominant hand, 99 (73.3%) physical therapists had no wrist pain, 104 (77%) had no thumb pain, 28 (20.7%) had mild wrist pain and 20 (14.8%) had mild thumb... Continue Reading
