Psychophysiological biomarkers to assess the effectiveness of surface electromyography biofeedback as an alternative therapy to reduce chronic low back pain: protocol for a randomised controlled trial.

The prevalence of chronic low back pain (CLBP) among the Pakistani population is reported to be as high as 78%, leading towards different physiological and psychosocial alterations, with the worst cases suffering from disabilities. This study protocol will be a randomised controlled trial designed to compare the effectiveness of biofeedback surface electromyography (sEMG) for CLBP in the Pakistani population. This will be a single-centre study to be conducted on patients with CLBP randomised into two groups, namely, Group A (intervention group) and Group B (control group) to receive biofeedback sEMG therapy as an intervention or no intervention, respectively.

Relationship Between Genetic Variant Of OXTR (Rs53576) And MTNR1B (Rs1387153) And Symptoms Of Psychological Stress In Females With Gestational Diabetes Mellitus.

Objective: To assess the association of oxytocin receptor (rs53576) and melatonin hormone receptor 1B (rs1387153) gene single nucleotide polymorphisms with psychological symptoms in women with gestational diabetes mellitus.

Methods: The case-control study was conducted from May 1 to June 1, 2022, at the Department of Physiology, University of Karachi, in collaboration with the Department of Biological and Biomedical Sciences, Aga Khan University, Karachi, and the Department of Obstetrics and Gynaecology, Jinnah Postgraduate Medical Centre, Karachi. Fifty gestational diabetic pregnant women and ninety healthy pregnant women were recruited.

Effect of nature-based physical activity on post-traumatic growth among healthcare providers with post-traumatic stress.

The purpose of this randomized control trial was to observe the effect of nature-based physical activity in achieving post traumatic growth and to estimate the combined effect of nature and physical activity on the psychophysiological outcomes. A 3-month therapy was provided to participants meeting eligibility criteria to receive the walk-in nature (experimental group) or sit-in nature (control group) in the 1:1 ratio. At baseline and 3-month follow-up, participants were assessed with Trauma Symptom Checklist 40, Traumatic Stress Scale, Post-Traumatic Growth Inventory (PTGI), Cortisol, C-Reactive Protein (CRP), Interleukin-6 (IL-6), Brain-Derived Neurotropic Factor (BDNF) and heart rate variability.

Physiological biomarkers of chronic stress: A systematic review.

Objective: The basic objective of this systematic review was to identify potential biomarkers for chronic stress.

Methods: A systematic review of studies linking biomarkers in people with chronic stress was conducted using PRISMA guidelines. The last 40 years' studies were included in the systematic review with no age restrictions; animal studies were excluded from the study.

Frequency of Cervical Nodal Metastasis in Early-Stage Squamous Cell Carcinoma of the Tongue.

 Oral cavity carcinoma is an aggressive tumor, with the tongue being one of the most common subsites of involvement. Surgery is a gold standard method of dealing with advanced-stage tumors. However, for early-stage carcinomas of the tongue, the management remains controversial.

Relationship of Tumor Thickness with Neck Node Metastasis in Buccal Squamous Cell Carcinoma: An Experience at a Tertiary Care Hospital.

 Squamous cell carcinoma is the most common malignancy of the head and neck, with the buccal mucosa being the most common site involved. Early locoregional metastasis is a hallmark of this disease, and early stage tumors may harbor metastatic nodes that are occult. Certain parameters can help identify high-risk patients for whom the pattern of occult nodal metastasis can be predicted.

Pilonidal sinus involving the nasal bridge: a rare manifestation.

Pilonidal sinus is very commonly associated with the sacrococcygeal area, but its presence within the head and neck is still unknown to many. Once diagnosed, it is easy to treat and should, therefore, be kept in mind as a possibility when coming across a discharging sinus swelling. We share our experience of two cases of pilonidal sinus presenting over the nasal bridge and their management.

Oral neurovascular hamartoma: an extraordinary verdict in the oral cavity.

The presence of a neurovascular hamartoma within the oral cavity is truly a rare entity. Scarcely reported in the literature, these hamartomas are smooth, pinkish masses and are painless, and therefore difficult to diagnose. They are benign in nature and apply pressure to their surroundings.

Tuberculosis verrucosa cutis in a patient with keloid over ear lobule.

Tuberculosis (TB) is a global health problem with predominance in resource-poor countries. Extrapulmonary TB constitutes approximately 10% of the cases and can present as different forms depending on the route of entry. Cutaneous TB is a small subset of the extrapulmonary TB.

Knowledge about breastfeeding in accordance with the national policy among doctors, paramedics and mothers in baby-friendly hospitals.

Objective: To assess the knowledge about the National Breastfeeding Policy among paramedics, doctors and mothers in baby-friendly hospitals.

Methods: A cross-sectional questionnaire based survey was conducted at the Paediatrics and Obstetrics' department of Civil Hospital, Karachi, Jinnah Postgraduate Medical Centre and Liaquat National Hospital in May 2008. A questionnaire was developed which was based on National Breastfeeding Policy by the investigators after literature search.
