Effect of Nigella sativa on Estradiol Levels and Menopausal Symptoms in Post-Menopausal Females

Introduction: Menopause is the permanent cessation of menses, typically occurs in women of 45-55 years. Menopause is associated with a number of somatic, psychological and sexual symptoms due to decline in estradiol levels resulting in poor quality of life of postmenopausal females. Aims & Objectives: The purpose of the current study was to determine the effect of Nigella sativa on menopausal symptoms and estradiol levels in postmenopausal females. Place and duration of study: Department of Physiology PGMI, Lahore for 8 weeks. Material & Methods: It was an interventional study conducted on 30 postmenopausal females. Nigella sativa was administered in the dose of 1g/day after breakfast for a period of 8 weeks. Menopausal Rating Scale (MRS) was filled and blood sample was taken before and after giving Nigella sativa for estradiol and testosterone levels. Data was analyzed by paired t-test using SPSS-21 and p- value less than 0.05 was considered significant. Results: The result of the study showed that there was statistically significant reduction in the overall score of MRS (p = 0.001) and in all its domains, somatic (p=0.001), psychological (p=0.001) and urogenital (p=0.017). There was also significant improvement in blood estradiol level after 8 weeks of Nigella sativa administration (p= 0.021). Conclusion: Nigella sativa supplementation increases estradiol level and decreases menopausal symptoms severity as indicted by significant reduction in the 3 domains of MRS and may be used by postmenopausal females on regular basis to improve their quality of life.

Food Insecurity and its Effect on Mental Health: A Systematic Review

Introduction: Food security is a rising concern worldwide. It is estimated that more than one billion people lack adequate supply of dietary energy and that at least half that amount suffers from micronutrient deficiencies. It is influenced by several factors: income, employment, race/ethnicity and disability, which adversely affect health. Food security has been considered as a risk factor for depression, stress and anxiety. Aims & Objectives: The research aimed to find the effect of food insecurity on mental health using systematic analysis. Place and duration of study: Data was gathered using Google Scholar, Medline, Embase, Science Direct and books from studies conducted between 2015 and 2020. Material & Methods: Systematic analysis was conducted with references to the literature. Results: This review showed a strong link of food insecurity with mental health status like depression, anxiety, and stress. Conclusion: Based on the results of this study, the tests of depression and mental health in both secured and foodinsecure food areas should be mandatory at the primary health level. It is suggested that food insecurity interventions on national and regional levels may help reduce the prevalence of depression, anxiety, and stress and improve the overall mental health status of the community.

Comparison of Covid-19 IgG Anti-Spike Antibody Titer after Vaccination with Sputnik V in Seropositive and Naïve Vaccinees

Introduction: Immunity to SARS-CoV-2 has shown to reduce the risk of having a severe infection and initiate a good degree of disease protection. Studies assessing the antibody titer after vaccination can be very helpful to see whether previously infected individuals have better immunological response as compared to uninfected or antibody naïve individuals. Aims & Objectives: Comparison of Anti-spike IgG antibody among vaccinees with or without previous exposure to COVID-19. To determine whether single dose regimen can produce significant antibody titer amongst previously infected cases and design vaccine dosage regimens accordingly. Place and duration of study: This study was conducted at Chughtai Institute of Pathology from April 2021 to June 2021. Material & Methods: Blood samples were collected from 83 adult male and female vaccinees at baseline, 3 weeks after the first dose and finally 7 days after the second dose. Previously infected individuals’ record was noted separately. Samples were immediately analyzed using Abbott SARS-CoV-2 IgG II quant two step immunoassay. Data was analyzed using SPSS 23.0. A p-value of <0.05 was considered significant.Results: Majority of the candidates (57 %) were females and on analysis it was found that 42% of the patients were seropositive whereas 58% of the patients were antibody naïve before receiving the first dose of vaccine. There was a significant difference between mean antibody titer of seropositive and seronegative study participants at day 0, day 21 and finally on day 28 (p value <0.001) with seropositive individuals having higher antibody titers even after first vaccine shot. Conclusion: Post vaccination immunological response was higher in seropositive individuals as compared to the antibody naïve and this finding can help the policy makers to design a single dose vaccine regimen for the former category.

Determination of Postmortem Interval by Estimating CSF Proteins Concentration after Death, by Dye Binding Method at a Tertiary Care Hospital in Lahore, Pakistan

Introduction: Postmortem interval (PMI) is the time lapse between death of a person and its postmortem examination i.e. autopsy. Estimating the postmortem interval (PMI) is an imperative perspective of forensic medicine. Aims & Objectives: This study was conducted to see the impact of CSF protein estimation on determination of PMI. Place and duration of study: It was an observational correlational study, conducted for one year at Department of Forensic Medicine, King Edward Medical University Lahore. Material & Methods: A total of 119 cadavers were included in this study. Chemicals used were disodium molybdate, pyrogallol, succinic acid. The minimum detectable concentration of total proteins in CSF with dye binding method using pyrogallol red was determined as 0.022g/l. Two ml of CSF was taken from each cadaver. Clear, colorless samples were taken in test tubes. Turbid and blood contained samples were not included in study. Protein concentration was determined using photospectrometry. Statistical analysis was done by SPSS-23. Quantitative variables like age were presented as mean ± SD. Qualitative variables like gender were presented as frequency and percentages. For comparison between PMI and CSF proteins concentration correlation was applied. Results: Males accounted for majority of our subjects. The mean value of proteins in CSF was 219.91± 113.121 mg/dl. The most common PMI was 11 to 20 hours. CSF proteins increased gradually over 72 hours after death. The results of present study showed a significant positive correlation between time of death and CSF proteins concentration after death. Conclusion: It is observed that as a whole protein concentration increased with increasing time of death. Hence, CSF protein concentration can be used in estimating time since death.

Results: It was revealed that 85.2% of the respondents reported minimal psychological impact, 14.8% had mild to moderate anxiety levels and 0.4% reported marked to severe anxiety. The impact was 2.5 times greater in subjects belonging to lower socioeconomic status (p=0.02). Conclusion: Population belonging to lower socioeconomic class is more vulnerable to be impacted by psychological disturbances due to the pandemic owing to economic losses that are magnified in the population with fragile earning sources.

Effect of Honey on Orthodontic Tooth Movement and Osteoclastic Activity in Psychologically Stressed Animals

Introduction: Orthodontics is a clinical specialty in dentistry related to the correction of dentofacial deformities. Psychological stress factors delay Orthodontic tooth movement (OTM). Honey can be considered a useful and harmless natural product to reduce stress levels, hence improves the efficacy of OTM. Aims & Objectives: To compare the differences in the rate of tooth movement and osteoclastic activity between control, psychologically stressed and honey treated psychologically stressed groups after 1 week of orthodontic force application in an animal model. Place and duration of study: This experimental study was conducted at the animal research laboratory and Histopathology Department of Post Graduate Medical Institute (PGMI), Lahore, Pakistan, from April 2019 to June 2020. Material & Methods: Thirty-six Sprague Dawley rats were randomly divided into A, B and C groups. Psychological Stress was induced in group A (PS group) while Honey was given orally as a therapeutic agent along with induction of psychological stress in group B (PSH group), and group C was the Control Group. Statistical analyses were performed using SPSS version 24 software. The quantitative variables were the orthodontic tooth movement, the osteoclast count, and the expression of RANKL. One-way ANOVA was applied to calculate the mean difference and Post hoc Tukey test applied for multiple comparisons among the groups. A p-value ? 0.05 was considered statistically significant in all 3 groups. Results: There was a significant difference (p-value <0.05) between control and experimental groups in the orthodontic tooth movement and levels of RANKL, however, there was no significant difference between PS and PSH groups. Conclusion: Psychological stress delays orthodontic tooth movement by causing a reduction in its rate and osteoclastic activity and honey has no significant correlation with lowering stress levels, hence does not improve orthodontic tooth movement efficiency.
