1. The effects of thyroxine treatment on soleus and extensor digitorum longus (EDL) muscle contractions and their cyclic adenosine 3',5'-monophosphate (cyclic AMP) levels were examined in anaesthetized cats. 2. Thyroxine treatment decreased the tension of incomplete tetanic contractions of the soleus as well as the EDL muscles. The effect on tension of these muscles was not associated with an increase in the cyclic AMP level of the muscle as is the case with a beta 2-adrenoceptor agonist effect. 3. The results do not support the involvement of cyclic AMP in the tension depressant effect of thyroxine on contractions of skeletal muscle. 4. It is suggested that the muscle weakness and tremor observed in thyrotoxicosis and during administration of beta 2-adrenoceptor agonists are mediated by different mechanisms.
Background: The 2019 coronavirus disease (COVID-19) outbreak, which was brought on by the SARS-CoV-2 novel coronavirus, has had a significant negative influence on our environment and exposed health-care personnel to a new level of risk. Very few studies have addressed the disturbances in the sleep quality of healthcare workers during COVID-19 pandemic. Aim and Objectives: The primary objective of the study was to examine the sleep quality of frontline healthcare workers during COVID-19 pandemic in a tertiary care center in northern Kerala. Materials and Methods: Healthcare workers belonging to a tertiary care center were invited to participate in the study. An online questionnaire including sociodemographics, Pittsburgh sleep quality index, and Insomnia severity index was used to evaluate sleep disturbances in healthcare workers. Univariate and bivariate analysis of the results were done to identify the predictors of poor sleep quality. Results: A total of 250 frontline healthcare workers were enrolled in the study, out of which 243 participants provided usable responses. About 27.6% of health workers showed features of poor sleep quality. The prevalence rate of poor sleep quality was highest among nurses, 55.2% followed by doctors and ambulance drivers, 22.4% and 11.9%, respectively. About 17.7% of the study population had subthreshold insomnia and 1.2% had clinical insomnia of moderate intensity. Conclusion: The prevalence of poor sleep quality is high among healthcare workers confronting COVID pandemic. This study emphasizes the need to implement specific protective measures for maintaining the sleep quality and decreasing stress among frontline health care workers during pandemics.
Background: The physical, social, and emotional difficulties posed by chronic illnesses can result in depression, anxiety, and stress, which are common mental health conditions. The severe acute respiratory syndrome-CoV-2 virus, which causes the novel respiratory illness COVID-19, has had a significant impact on the global population, especially those who already have underlying chronic illnesses. In this study, we tried to evaluate the psychological stress, depression, and anxiety experienced by COVID-positive patients with and without chronic health conditions, while they are quarantined as a result of the COVID-19 pandemic. Aim and Objectives: The objectives of this study were to assess the prevalence of depression, anxiety, and stress among COVID-positive patients and to compare the prevalence of depression, anxiety, and stress among COVID-positive patients with and without chronic illness in a district in North Kerala. Materials and Methods: This observational and cross-sectional study was carried out in a district in the northern state of Kerala, India. A study population of 251 individuals who had positive COVID tests participated in the study. Out of this group, 117 people had chronic health problems such as high blood pressure, diabetes, and heart disease, while the remaining 134 people were without any chronic illness. An online questionnaire including sociodemographics and depression, anxiety, and stress scale -21 was used to evaluate depression, anxiety, and stress among the participants. Results: COVID patients with chronic illnesses experienced severe depression at a rate of 77.8% compared to 20.1% in those without any chronic illness. Patients with chronic illnesses who tested positive for COVID-19 also experienced severe anxiety in 77.8% of cases, compared to the 23.8% of really severe cases of anxiety among COVID patients who do not have any chronic illnesses. Moderate stress levels were observed in 76.06% of COVID patients with chronic illness when compared to 22.4% in those with no comorbidities. Conclusion: According to the study’s findings, people with chronic illnesses experience higher levels of stress, anxiety, and depression than those who do not have those conditions. The existence of such a high prevalence and severity of psychological issues among quarantined patients with COVID-19 underscores the need for serious attention to the mental health status of these patients.
INTRODUCTIONMenopause is the time when permanent cessation of menstruation occurs following the loss of ovarian activity. The years prior to menopause that encompasses the change from normal ovulatory cycles to cessation of menses are known as peri-menopausal transitional years. It takes twelve months of amenorrhea to confirm that menopause has set in and therefore it is a retrospective diagnosis.During menopause, the levels of estrogen and progesterone are very low. In menopausal women the levels of Mg 2+ were sufficiently higher than the levels seen in normal cycling women. It was concluded that Mg 2+ level was inversely and significantly related to serum estrogen levels in menopausal women and in reproductive age group.It has been well documented that during the menopausal stage of a women's life, bone metabolism is increased to a point where breakdown is more prevalent than build up. ABSTRACTBackground: Menopause is the time when permanent cessation of menstruation occurs following the loss of ovarian activity. Though there is a relation between the divalent cations and sex hormones, and the lack of sufficient literature on their relation with sex hormones, the present study was conducted to compare and correlate the relation between levels of sex hormones and divalent cations in normal healthy menopausal women and the different phases of menstrual cycle in healthy women of reproductive age group. Methods: The study was performed after institutional ethical clearance and informed consent from all the subjects. The study included three groups of 30 subjects each of reproductive age and postmenopausal women with less than 10 years of menopause and more than 10 years of menopause. Blood samples were obtained from the control group, one each in early follicular phase, ovulatory phase and during luteal phase for estimation of calcium, magnesium and the level of sex hormones and compared with that of postmenopausal group using commercially available kit. The values are expressed as mean ± S.D. The comparison between the different phases of menstrual cycle in reproductive age group with menopausal women was performed using student t test. Correlation between different parameters were done using Pearson correlation test. P value less than 0.05 was considered significant. Results: The correlation of progesterone with magnesium and calcium/magnesium ratio in women of reproductive age group was significant. The correlation of estrogen with calcium and magnesium in women more than 10 years after menopause was found to be significant. Conclusions: A low level of estrogen supplementation may be more acceptable, because of its negative correlation with serum magnesium, and thus helping to maintain an adequate protective level of Mg 2+ circulating in the blood. Therefore, it is necessary for maintaining optimum Ca
