abstract = {Introduction: Excessive smartphone usage among adolescents and young adults has been consistently linked to poor sleep. Moreover, smartphone overuse has been associated with daytime tiredness, longer sleeps latency, and reduced sleep duration. The significance of addressing poor sleep among adolescents and young adults is underscored by recent research linking it to adverse physical and psychological health outcomes, such as mood disturbances, impaired cognitive function, and increased risk incidence of hypertension and diabetes.
Aim: To evaluate the effects of smartphone usage on sleep quality among individuals using Pittsburgh Sleep Quality Index (PSQI) and hypnogram data.
Materials and Methods: In this cross-sectional observational study, sleep patterns were assessed using the PSQI questionnaire and Prime Nap sleep tracker app (version 1.1.4). The study was conducted by Deccan College of Medical Sciences, Hyderabad, Telangana, India. The data was collected in the form of a hypnogram and the study was conducted in the participants’ homes (under domicile conditions) in the city of Hyderabad, Telangana, India from March 2020 to April 2020. A total of 60 participants (both male and female) in the age group of 15-25 years were recruited and divided into two groups: one comprising 30 individuals with regular prolonged exposure to smartphone screens at night, and the other consisting of 30 individuals who experienced minimal or no smartphone exposure once they prepared to sleep. Descriptive statistics were applied to the collected data using Microsoft Excel and IBM Statistical Package for Social Sciences (SPSS) for Windows version 25.0.
Results: Adding up the average scores of the seven factors gives a global PSQI score from 0 to 21, with 0-4 indicating good sleep and 5-21 indicating poor sleep. Among those who used smartphones regularly at night time, 20 participants (66.67%) had PSQI score >5 and poor sleep quality, 24 participants (80%) had prolonged sleep latency, 18 participants (60%) had poor sleep duration, 27 participants (90%) had sleep disturbances, and 22 participants (73.33%) had increased daytime dysfunction. Hypnogram abnormalities were seen in >15 participants (50%) of subjects.
Conclusion: The prevalence of smartphone addiction is widely acknowledged in the medical literature, highlighting the need for its assessment, especially among adolescents and young adults. The study reveals that poor sleeping habits among participants were attributable either to a lack of awareness or neglect. By recognising the importance of adequate sleep, improvement in the quality of daily activities can be made by reducing daily screen time, consequently alleviating both physical and mental stress. Furthermore, the findings have implications for individuals whose work involves prolonged exposure to computer screens, especially during night time.},

abstract = {Introduction: Physical inactivity is a rapidly evolving public health issue that contributes to a wide range of chronic diseases and health consequences, including obesity, diabetes, and cancer. In addition to improving a patient’s overall health, increased physical activity has been demonstrated to be beneficial in the management of chronic conditions. The purpose of this research is to discover if there is a link between physical activity intensity and HbA1c levels in non-diabetic adults and, if so, which type of physical activity has the most impact on glycemic control.
Material and Methods: There were 90 healthy non-diabetic individuals in the study. The International Physical Activity Questionnaire (IPAQ) score was calculated after each subject’s physical activity questionnaire was evaluated. Based on their IPAQ scores, the participants were split into three groups: low, moderate, and vigorous physical activity. A 3 mL blood sample was taken in a vacutainer to determine HbA1c levels. The data was produced in Microsoft Excel and analyzed using the statistical application SPSS 17.0.
Result: HbA1c values were statistically significant in the moderate-physical-activity group, while IPAQ showed a statistical difference between males and females in the vigorous-physical-activity group. In all three groups, IPAQ scores were significantly different but not in HbA1c levels. The HbA1c and IPAQ scores had a modest negative connection. The difference between males and females in our study was statistically insignificant. The body mass index (BMI) and HbA1c, as well as BMI and IPAQ, were found to have a positive linkage.
Conclusion: Physical activity, particularly moderate-to-vigorous activity, has a bigger influence on non-diabetic people’s glycemic regulation.},

abstract = {Background: Stressful environment in medical school often has a negative effect on students’ psychosocial well‐being and COVID-19 has a further additive effect on it. The COVID-19 pandemic is found to affect the mental health of the population. Undergraduate medical students are especially prone to mental health disorders and hence could be more vulnerable to the impact of the pandemic. An in‐depth understanding of how medical students experience psychological distress and coping is necessary for prospective students.
Aim and Objective: To determine the effect of COVID-19 on mental health of medical students.
Methods: A web-based cross-sectional study was carried out on 299 undergraduate medical students in the medical colleges of Telangana and Andhra Pradesh, India. They were divided into 4 groups based on whether the participants, their family members, both or none of them were affected with COVID-19 infection. The questionnaires provided to the participants in this study consisted of three components – (i) the demographic information that required participants to provide their gender, age and year of study (ii) COVID-19 related questionnaire and (iii) Depression, Anxiety, and Stress Scale‐42 (DASS-42) items to measure the levels of psychological distress among participants. Chi square statistical test and One-way analysis of variance (ANOVA) were the statistical tools used in this study.
Results: It was observed that depression (χ=9.839, p=0.043) was found to be significant in participants who were not affected with COVID-19 infection. Statistically significant differences were observed in participants’ depression (χ=11.976, p=0.018) and stress (χ=9.839, p=0.043) levels whose family members were affected with COVID-19. One way ANOVA showed that anxiety levels (F(3,295)=4.267, p=0.006) was significantly higher when both participants and their family members (group 3) were affected with COVID-19 infection.
Conclusion: This study has shown that COVID-19 pandemic and subsequent lockdowns affected the mental health of young population.},

Prolonged use of high heels causes elevation or collapse of these arches by stress and strain over the weight-bearing bones, and also causes damage to the underlying soft tissues and ligaments. The aim of this study was to document the presence of any changes in medial longitudinal arches in young women using high heels through radiographic method taking into account body mass index, height of heels, and the type of shoes worn and to document lower back pain and foot pain.
Material and Methods: An observational study between 40 high-heel wearers and 40 flat wearers was done. Lateral radiographs of both feet were taken in weight-bearing position with medial border of the foot touching the cassette. Lateral talocalcaneal angle, lateral talar-first metatarsal angle, angle of longitudinal arch, and calcaneal pitch were measured by a protractor and goniometer. A questionnaire documented complaints of back pain and foot pain.
Results: Independent sample t-test showed a statistically significant difference in left lateral talar-first metatarsal angle between two groups. Pearson's correlation showed a negative correlation between left lateral talocalcaneal angle and low back pain, and a positive correlation between right lateral talar-first metatarsal angle and low back pain.
Discussion and Conclusion: Frequent and prolonged use of high-heeled footwear can result in damage to the foot architecture leading to foot and back pain. Thus, keeping the high heels reserved for occasional use is the best choice.},

Aims: The aim of this study was to correlate the systolic and diastolic time (DT) intervals (preejection period [PEP], ejection time [ET], upstroke time [UT], DT, pulse duration [PD], and ejection slope [ES]) of pulse waves recorded from all four limbs in relation to age, gender, weight, height, heart rate, and blood pressure and to compare these cardiac time intervals between individuals with or without parental history of hypertension. Settings and Design: Ninety-eight healthy MBBS students in the age group of 19–21 years were included. Subjects and Methods: Students' history and demographic data were noted. Anthropometric measurements were recorded. The measurement of peripheral arterial pressures (in all four limbs) and determination of cardiac intervals (PEP, ET, UT, DT, PD, and ES) was done by PeriScope™. Statistical Analysis Used: Data were analyzed using SPSS version 17.0. Results: Independent sample t-test showed statistically significant differences between genders with weight, height, waist circumference, and waist–hip ratio. Statistically significant differences existed between right arm systolic blood pressure, left arm systolic blood pressure, and left arm pulse pressure among males and females. Significant differences among males and females were observed in some of the cardiac time intervals. Mean arterial blood pressure recorded in all four limbs showed a significant negative correlation with right arm ES in males and left arm ES in females. Conclusion: Since gender, anthropometric parameters, and blood pressure influence cardiac time intervals, these should be adjusted for when deriving inference on left ventricular performance.},

abstract = {Background: The use of mobile phone has increased excessively these days which can have a deleterious effect on human tissues and organs, especially cardiovascular system (CVS). The effects on CVS can be detected at an early stage by analyzing alterations in heart rate variability (HRV).
Aims and Objectives: This study was designed to determine the effect of mobile phone use with different components of HRV.
Materials and Methods: In our study, HRV was measured in 95 college-going students (males: 49 and females: 46) using root mean square polyrite-D during 3 phases with each phase being recorded continuously for 2 min: Phase 1: Basal recording; Phase 2: Mobile phone use during active call with direct contact to the ear; and Phase 3: Mobile phone use during active call with earphones. Data obtained were subjected to statistical analysis using repeated measures non-parametric test followed by multiple comparison tests.
Results: There was a significant increase in mean HR and decrease in mean RR interval from baseline through Phase 3 to Phase 2. This study shows that there was statistically significant change in root of the mean of the sum of the squares of differences, low frequency (LF), high frequency (HF), and LF/HF ratio between basal recording and during active call (direct contact of mobile phone to the ear and also with use of earphones); however, no change was seen between direct contact of mobile phone to the ear and during the use of earphones. Standard deviation of all normal-to-normal intervals did not show any significant change. We also observed gender differences in some of the HRV parameters.
Conclusion: There is a considerable effect of mobile phone use on HR and HRV parameters. Furthermore, the changes noted are less with earphone use than when compared with the use of mobile phone in direct contact with the ear though these differences were not significant statistically.},

abstract = {Background and Aim: Diabetes and cholelithiasis are common diseases worldwide in this era of modern epidemics of non - communicable diseases. Studies revealed that diabetes is a risk factor for gallstones. Since both diseases are related to altered carbohydrate and lipid metabolism, we hypothesized that the vice‑versa, i.e., gallstone disease can be a risk factor for the development of diabetes. The aim of this study was to find the prevalence of diabetes mellitus among ultrasonographically diagnosed cholelithiasis patients and to find any correlation between parameters of gallstones and diabetes mellitus. Methods: This was a hospital‑based observational study. A total of 31 gallstone patients belonging to both genders (male = 9, female = 22) and in the age group of 20–80 years were enrolled in the study. From ultrasound report, parameters noted were: size of gallbladder, solitary or multiple gallstones, and size of the largest gallstone. All patients were asked about history of diabetes mellitus, (if history of diabetes is present – whether the diabetes was diagnosed before or after cholelithiasis), monthly family income, education status, and occupation. Data obtained were subjected to appropriate statistical analysis. P < 0.05 was considered statistically significant. Results: In this endeavor, we found that the prevalence of diabetes among cholelithiasis patients was only 35.48%; and of the 11 diabetic patients, 3 developed gallstones before the diagnosis of diabetes mellitus. Socioeconomic status did not have any bearing on the occurrence of diabetes and gallstones in our patients. Glycated hemoglobin levels did not correlate with the severity of gallstone disease which is assessed in the form of solitary/multiple stones and size of the largest gallstone. Conclusion: There is no increased prevalence of diabetes among cholelithiasis patients. Our hypothesis of gallstones acting as risk for developing diabetes could not be proved.},

abstract = {Background: Chronic diseases such as hypertension and diabetes have shown improvement in disease condition on isotonic exercises. But the same can cause deterioration in the health of patients with asthma, heart failure, and chronic obstructive pulmonary disease. Therefore, in such individuals, isometric exercise can be given a try. Isometric exercise is known to activate the autonomic nervous system, especially the parasympathetic fibers and thus has a bearing on the functioning of respiratory system.
Aims and Objectives: This study was undertaken with a purpose to find acute change in respiratory reserve during handgrip exercise.
Materials and Methods: 50 young apparently healthy volunteers between the ages of 18 to 35 years were enrolled for the study. Different spirometry volumes and capacities including inspiratory reserve volume (IRV) and expiratory reserve volume (ERV) were recorded on MedSpiror (RMS, Chandigarh, India) at baseline and during sustained hand grip using a hand dynamometer. Statistical analysis was done using SPSS 17.0 on the data obtained.
Result: This study showed that FVC was significantly reduced during handgrip exercise. FEV1, PEFR, FEF 25-75% and IRV decreased while FEV1/FVC and ERV increased but these changes were not significant statistically.
Conclusion: The reserve capacity of the lung does not change significantly during isometric exercise.},

abstract = {Background: the reactive oxygen species (ROS) are involved in multiple reproductive processes – maturation of oocyte, fertilization, development of embryo, pregnancy and parturition. However, the optimal levels and interplay of oxidants and antioxidants is crucial for a positive pregnancy outcome. Pregnancy induced hypertension (PIH) is shown to have defective trophoblast invasion leading to high pressures in utero-placental circulation; thus this stress imposed on placenta may disturb the oxidant-antioxidant balance.
Aim: the purpose of this study was to assess the oxidative stress during uncomplicated pregnancy and pregnancy associated with hypertension in primi-gravida women.
Materials and methods: a total of 90 women were enrolled and divided into 3 groups. Group 1: Healthy non-pregnant women (n=30), Group 2: Normotensive primi-gravida women (n=30) and Group 3: Pre-eclamptic primi-gravida women (n=30). Blood samples were analyzed for levels of malondialdehyde (MDA), superoxide dismutase (SOD), total anti-oxidant capacity (TAC) and uric acid using appropriate biochemical methods. ANOVA was used for assessing the difference between the groups and statistical significance was fixed at p<0.05.
Results: in the present study, levels of MDA, SOD and uric acid were significantly increased in pregnant compared to non-pregnant women and to a greater extent in pre-eclampsia women compared to normal pregnant women.TAC levels were significantly decreased in pregnant when compared to non-pregnant and much more decreased in pre-eclampsia women compared to normal pregnant women.
Conclusion: high pressures in feto-placental circulation can lead to increased elaboration of oxidative radicals which may cause oxidative damage to placenta and other organs.},
