An analysis of retracted studies in cardiology in the last two decades.

Background: The aim of this study is to analyze retracted studies in cardiovascular field. Methodology: PubMed and Embase databases were used to identify retracted publications from 2002 to 2022. Various characteristics of articles were retrieved, and an analysis was performed using R software. Results: We finally included 979 articles. Authors from China have the highest number of retracted studies (35.5%), followed by the USA (22.1%), and Japan (4%). The most common causes of retraction are mistakes and honest errors (24.5%) and duplicate data (17.7%). From 2002 to 2022, there has been a significant increase in retracted studies and a decrease in the impact factor of journals, number of citations, and time to retraction. Conclusion: The trend of retracting publications in cardiology is increasing.

Retracted publications are withdrawn publications. Recently, the number of retracted publications has increased. In our research, we try to find the characteristics and pattern of the retracted studies in heart published studies. PubMed and Embase databases were used to identify retracted publications from 2002 to 2022. Various characteristics of articles were retrieved, and statistical software was used to analyze them. We finally included 979 articles. Findings from our research showed authors from China, the USA, and Japan have the highest number of retracted studies. Honest errors, duplicate data, and fabricated data are common causes of retractions. From 2002 to 2022, there has been an increase in the number of retracted studies and a decrease in the impact factor of journals, the number of citations, and the time to retraction. We also compared the results between the first (2003­2012) and the second decade (SD; 2013­2022). In the SD, there are more retracted publications. We saw that in the first decade, the USA had more retractions; however, in the SD, China had more retractions. The retracted publications in the SD have less time to retract and fewer citations. There is no change regarding the funding of research or the parties' interest in conducting research. In the end, the trend of retracting publications in heart studies is increasing. Making the scientific world aware would be the most important to tackle this problem.

Prevalence of dyslipidemia, hypertension and diabetes among tribal and rural population in a south Indian forested region.

While NCDs are in rise globally, tribal and rural populations residing near to reserve forests with limited exposure to modern lifestyles may bear a unique burden. This study investigates the prevalence and risk factors of hypertension, diabetes, and dyslipidemia among these communities. We conducted a cross-sectional study between 2018 and 2020 in the forest-dwelling population of Chamarajanagar, India. Using multistage stratified sampling based on caste and remoteness, we enrolled 608 participants aged over 18 years, including 259 non-tribal and 349 tribal individuals. Data collection includes the administration of STEPS questionnaire and measurement of fasting blood sugar, lipid levels, and blood pressure. The prevalence of diabetes, hypertension, and dyslipidemia were 4.6%, 28.8%, and 85.7%, respectively, among the study population. We also found abnormal levels of low-density lipoprotein (LDL), high-density lipoprotein (HDL), Triglycerides (TGA), Total cholesterol (TC), and very low-density lipoprotein (VLDL)in 4.9%, 82.4%, 22.7%, 5.8%, and 7.4% of participants, respectively. Significant differences were observed in diabetes, LDL abnormality, TGA abnormality, VLDL abnormality, and TC abnormality, but not in hypertension, dyslipidemia, or HDL abnormality, across the Socio Geographic Discrimination Index. We found a significant difference in diabetes and HDL abnormality, but not in hypertension, dyslipidemia, LDL abnormality, TGA abnormality, TC abnormality, or VLDL abnormality, between tribal and non-tribal populations living in the forest-dwelling area. Waist circumference was a significant independent predictor of diabetes among tribal participants, while wealth index, age, and waist circumference were significant predictors of hypertension. There were no significant predictors for dyslipidemia among tribal participants. Our study suggests that tribal population living in a remote area are at a lower risk of developing diabetes compared to non-tribal populations living in the same geographic area. However, the prevalence of hypertension and dyslipidemia among tribal populations remains high and comparable to that of the general population.

A study of clinical profile, sequelae of COVID, and satisfaction of inpatient care at a government COVID care hospital in Karnataka.

Background: Coronavirus disease 2019 (COVID-19) is caused by SARS-CoV-2 virus has increased the morbidity and mortality across the world. The most common symptoms are fever, dry cough, tiredness, and the least common symptoms are aches and pains, sore throat, diarrhoea, conjunctivitis, headache and loss of taste or smell. In this current pandemic, the number of COVID-19 survivors being discharged from the hospital is increasing day by day and the long-term effect among the survivors is also increasing. Fatigue and dyspnea were the most reported Post COVID symptoms. The presence of these symptoms is also known as "Long COVID". COVID-19 disease has not only affected the physical health but also the mental health of the patients which also had led to decrease in their quality of life. Material and Methods: A retrospective cross-sectional study was conducted among 35 patients who were admitted in District hospital in Mysuru during the month of October 2020. Purposive Sampling was adopted for selecting the patients. Data was collected through telephone after their discharge. Data were entered in Microsoft Excel sheet and analysed using SPSS trial version 23. Descriptive statistics such as percentages and proportions were calculated. To see the association between the variables, Chi-square test, Fischer's exact test was used. P < 0.05 was taken as statistically significant. Results: The mean age of the study participants was 49.1 years. Majority of them had fever (68.6%) followed by Myalgia (65.7%), cough (60%), fatigue (42.9%), headache (37.1%) Majority of the patients had no symptoms after discharge (65.7%). After being discharged from the hospital, 22.9% of patients had difficulty in sleeping, 17.1% had loss of taste/smell and fatigue, 8.6% of them had breathlessness and 5.7% of the patients had a change in voice and loss of appetite. Conclusion: With the increasing number of cases across the world, we will most likely face an ongoing wave of COVID-19 sequelae. To Prevent this, an extensive rehabilitation program is necessary for patients during hospitalization and after discharge.

Ghrelin attenuates methylmercury-induced oxidative stress in neuronal cells.

Methylmercury (MeHg) is a global pollutant, which can cause damage to the central nervous system at both high-acute and chronic-low exposures, especially in vulnerable populations, such as children and pregnant women. Nowadays, acute-high poisoning is rare. However, chronic exposure to low MeHg concentrations via fish consumption remains a health concern. Current therapeutic strategies for MeHg poisoning are based on the use of chelators. However, these therapies have limited efficacy. Ghrelin is a gut hormone with an important role in regulating physiologic processes. It has been reported that ghrelin plays a protective role against the toxicity of several xenobiotics. Here, we explored the role of ghrelin as a putative protector against MeHg-induced oxidative stress. Our data show that ghrelin was able to ameliorate MeHg-induced reactive oxygen species (ROS) production in primary neuronal hypothalamic and hippocampal cultures. An analogous effect was observed in mouse hypothalamic neuronal GT 1-7 cells. Using this model, our novel findings show that antioxidant protection of ghrelin against MeHg is mediated by glutathione upregulation and induction of the NRF2/NQO1 pathway.

Screening for mental illness using GMHAT App of patients with Type 2 diabetes mellitus at a teaching institute hospital in India - A cross sectional study.

People with diabetes will have some coexisting mental illness most of the time and its evaluation and management are essential for the well-being of the person. With this background, the Global Mental Health Assessment Tool (GMHAT) app was used to screen for mental illness among type 2 diabetes mellitus patients attending a tertiary care hospital in Mysore, India. Methods: A cross-sectional study was conducted on 100 patients who were on treatment for type 2 diabetes for at least 6 months from the Out-Patient Department of KR Hospital, Mysore. Interviews were conducted using a structured GMHAT. Data were entered in MS Excel and analysed using SPSS version 21.0. Chi-square, Independent T-test/Mann-Whitney tests were used to investigate associations between the variables. Results: The mean age of the study participants was 48.8 ± 11.6 years. Among the 100 diabetic patients, 39% (n = 39) had mental illness and among the 39 subjects, 21% had depression, 14% had anxiety disorder and 4% suffered from organic disorder. Apart from diabetes, 29, 17, 13, 27, 23 and 20% had hypertension, chronic kidney disease, liver disease, retinopathy, neuropathy and nephropathy, respectively, as comorbid conditions. Conclusion: There is a higher prevalence of mental illness in patients with diabetes mellitus. The prevalence rate increases with an increase in the chronicity of diabetes. The use of the GMHAT app could help in rapid assessment and accurate diagnoses.

Global Awareness of Myocardial Infarction Symptoms in General Population: a Systematic Review and Meta-Analysis.

BACKGROUND AND OBJECTIVES: Knowledge about myocardial Infarction (MI) symptoms is crucial because inadequate awareness ensures direct association with patient delay and adverse health events subsequently. METHODS: PRISMA guidelines were followed while conducting the systematic review with PROSPERO number CRD42020219802. An electronic search was conducted comprehensively through 5 databases to find those relevant articles systematically. Prevalence was calculated for each typical symptom of MI separately and subgroup analysis according to continent, country, gender and ethnicity was done. Meta-Analysis was conducted by using statistical software R version 3.4.3. A random-effects model was used. RESULTS: Studies from 35 different countries with 120,988,548 individuals were included in the final analysis. The prevalence of chest pain awareness was highest, while it was lowest for jaw, back, and neck pain. There was no difference in terms of awareness in males and females. Prevalence of awareness of typical MI symptoms was higher in the Caucasian white, white, and non-Hispanic white groups than in other groups. The prevalence varies from less than 5% in African countries such as Kenya, Tanzania and Asian countries such as Nepal to as high as 90% in Germany. CONCLUSIONS: People are well aware of chest pain as a symptom of MI. However, there is limited knowledge regarding other typical symptoms of MI.

The antioxidant role of STAT3 in methylmercury-induced toxicity in mouse hypothalamic neuronal GT1-7 cell line.

Oxidative stress, impairment of antioxidant defenses, and disruption of calcium homeostasis are associated with the toxicity of methylmercury (MeHg). Yet, the relative contribution and interdependence of these effects and other molecular mechanisms that mediate MeHg-induced neurotoxicity remain uncertain. The signal transducer and activator of transcription 3 (STAT3) is a transcription factor that regulates the expression of anti-apoptotic and cell cycle progression genes. In addition to its role in cell growth and survival, STAT3 regulates redox homeostasis and prevents oxidative stress by the modulation of nuclear genes that encode for electron transport complexes (ETC) and antioxidant enzymes. Here we tested the hypothesis that STAT3 contributes to the orchestration of the antioxidant defense response against MeHg injury. We show that MeHg (>1 µM) exposure induced STAT3 activation within 1 h and beyond in mouse hypothalamic neuronal GT1-7 cells in a concentration-and time-dependent manner. Pharmacological inhibition of STAT3 phosphorylation exacerbated MeHg-induced reactive oxygen species (ROS) production and antioxidant responses. Finally, treatment with the antioxidant Trolox demonstrated that MeHg-induced STAT3 activation is mediated, at least in part, by MeHg-induced ROS generation. Combined, our results demonstrated a role for the STAT3 signaling pathway as an early response to MeHg-induced oxidative stress.
