Effects Of Excessive Screen Time During Online Teaching On The Physical And Mental Health Of Medical And Dental Students.

To assess the effects of excessive screen time on the health of medical and dental students due to online teaching during the COVID-19 pandemic. It was a descriptive cross-sectional study, conducted in Bahria University of Health Sciences from June 2022 to September 2022 after getting ethical approval. A total of 200 students who attended online teaching modules for at least one year through online teaching Apps, were included. A structured questionnaire was distributed using google forms. The results revealed that factors including strain on the eyes, restlessness, declined academic performance and exercise during lockdown, along with feeling connected as a group had a significant association with increased screen time. Excessive screen time has various adverse effects on the physical and mental health of medical and dental students. For improving students' physical and mental health during online teaching we need to change teaching strategies and support the introduction of flipped classroom.

Follicular sensitivity index and insulin growth factor-1: Predictor of success after intracytoplasmic sperm injection.

To compare follicular sensitivity index (FSI) and Insulin Growth Factor (IGF) -1 for prediction of oocyte yield, embryo quality and the pregnancy consequence in infertile females booked for Intracytoplasmic Sperm Injection (ICSI). Study design was cross sectional where in 133 infertile females enrolled for ICSI were included. Antral follicle count (AFC), Pre-ovulatory follicle count (PFC), FSI, total dosages of follicle stimulating hormone (FSH); designed as pre-ovulatory follicle count × 100,000/ (antral follicle count × total administered stimulation doses) were estimated. IGF was measured by Enzyme Linked Immuno Sorbent Assay. Efficacious pregnancy conception after Intracytoplasmic Sperm Injection (ICSI) was established by means of intrauterine gestational sac with cardiac activity after transfer of embryo. Odds ratio was determined for clinical pregnancy by means of FSI and IGF-I, p-values <0.05 were considered significant. FSI was found to be a stronger predictor of pregnancy than IGF-I. Both IGF-I and FSI contributed positive association with clinical pregnancy consequences but FSI was found to be a more reliable predictor of clinical pregnancy. The advantage of using FSI over IGF-I is that FSI is a noninvasive test while IGF-I needs blood sampling. We recommend calculation of FSI for prediction of pregnancy outcomes.
