Factors Associated with Dietary Diversity in Community-Dwelling Brazilian Older Adults

Background: Older populations are at high risk of nutritional inadequacy and monotonous diets, and assessing dietary diversity can be a practical measure to indicate groups at nutritional risk. We aimed to explore the dietary diversity of older adults enrolled in primary health care services in Brazil and to evaluate its associated factors. Methodology: In this cross-sectional study, we evaluated the dietary diversity score (DDS) of 581 participants (≥60 years) registered in primary care services. All foods mentioned in a 24 h food recall were classified into 10 groups, and factors associated with the DDS were analyzed using hierarchical linear regression models in two blocks: (1) sociodemographic and (2) health conditions and lifestyle. Results: The mean DDS was 5.07 (±1.34), and 67.5% of the sample reached the minimum dietary diversity (≥5 groups). In the final model, income, previous diagnosis of cancer, and sporadic intake of alcohol were positively associated with DDS. In contrast, cognitive decline, sedentary lifestyle, and anorexia of aging were negatively associated with DDS. Conclusions: These findings show that the entire structural, economic, and social system needs to facilitate access to quality food, adequate places and conditions for the practice of physical activity, and policies regarding tobacco and alcohol abuse, in addition to nutritional guidance.

Increased risk of stroke in non-rheumatic valvular disease associated with antiphospholipid syndrome (APS): a US nationwide study 2017-2019

Abstract Introduction Antiphospholipid syndrome (APS) is an autoimmune syndrome characterized by the presence of antiphospholipid autoantibodies, arterial and venous thrombosis, recurrent pregnancy loss and thrombocytopenia. Cardiac manifestations are also common which include coronary artery disease (CAD), non rheumatic valvular heart disorders (NRVHD), myocardial dysfunction, intracardiac thrombi and pulmonary hypertension. Valvular lesions occur likely due to immune complex deposition on the valves, causing fibrosis, calcification and subsequently valvular deformities. Literature review suggests prevalence of NRVHD in APS population is 30% and left sided valves are more involved than right. An increased risk of stroke has also been seen in APS patients with valvular disorders. Purpose Studies report variations in incidence of NRVHD in association with APS. To estimate the prevalence of NRVHD and their correlation with APS, we conducted a retrospective database analysis of hospitalizations across the United States. Additionally we investigated whether this association indicates a increased risk of ischemic stroke in this specific subpopulation. Methods The national inpatient sample (NIS) from 2017-2019 was queried for adult patients (age>18 yrs) admitted with a primary or secondary diagnosis of APS. These patients were stratified for different NRVHD including tricuspid stenosis, tricuspid insufficiency, pulmonary stenosis, pulmonary regurgitation, mitral stenosis, mitral insufficiency (MI), aortic stenosis (AS), and aortic regurgitation. Baseline risk factors and cardiac complications were compared. Multiple regression analysis was performed to study the association of NRVHD with stroke as the primary outcome in the subpopulation of APS hospitalizations. Results A total of 567600 adult patients hospitalized with diagnosis of APS were identified from the NIS 2017-2019 database. Among those, 33,095 had NRVHD with a mean age of 69 years. Of these, prevalence of males was 52.41% compared to females of 47.59%. In the cohort of APS, patients with NRVHD had a higher prevalence of coronary artery disease (43.78% vs 20.41%), diabetes mellitus (30.65% vs 27.56%), prior stroke (10.42% vs 7.78%) than those without valvular disorders. Among the APS population the most prevalent NRVHD were mitral insufficiency (MI), 2.45% and aortic stenosis (AS), 2.13%. In the cohort of NRVHD in APS hospitalizations, the odds of stroke was found to be 1.3 times higher with statistical significance (confidence interval (CI): 1.13-1.48, p <0.001) adjusted for relevant clinical and demographic risk factors such as tobacco abuse, CAD, diabetes mellitus, prior stroke. Conclusion This study shows 6.2% prevalence of NRVHD in APS population, of which MI and AS were common. NRVHD is also associated with higher odds of stroke in APS. Further studies are warranted in identifying the risk of stroke with NRVHD in APS population and emphasizing the need for early detection.

Flavokavains A- and B-Free Kava Enhances Resilience against the Adverse Health Effects of Tobacco Smoke in Mice

High prevalence of alcohol use disorder & psychiatric comorbidity among coal mine workers: Observations from a cross-sectional study in West Bengal.

Background & objectives Tobacco (30%), alcohol (21.4%) and cannabis (3%) are the three most commonly abused substances in India. Tobacco and alcohol abuse have higher prevalence rates among different occupational groups as compared to that in general population in the country. Both tobacco and alcohol lead to significant occupational harm in terms of absenteeism, injuries, sickness and lost productivity. This study estimated the patterns of substance use and associated common psychiatric comorbidity in a sample of coal mine workers. Methods Coal mine workers at the age of 18 yr or above engaged in mining activities (skilled/semi-skilled/unskilled) were recruited from the Raniganj - Asansol coal mining areas of Eastern Coalfields Limited (ECL). Participants were screened to identify patterns of substance use and other common mental health problems. All participants were administered ASSIST (The Alcohol, Smoking and Substance Involvement Screening Test); GENACIS (Gender, Alcohol and Culture: An International Study) modified questionnaire; and Hospital Anxiety and Depression Scale (HADS) for primary screening for anxiety and depression. Results Out of 202 participants 69 per cent (n=140) were found with either 'hazardous and harmful' (moderate risk); or 'dependent' (high risk) patterns of use of either tobacco or alcohol or cannabis or of more than one substance. Only 31 per cent (n=62) were 'low-risk' for all substances. Almost 65 per cent (n=132) and 49 per cent (n=99) participants out of the whole sample (n=202) belonged to 'hazardous and harmful' (moderate risk) and 'dependent' (high risk) pattern of tobacco and alcohol consumption, respectively. About 28.8 per cent (n=38) and 23.7 per cent (n=31) of all participants had anxiety and depression, respectively. Combined moderate to high use of both alcohol and tobacco use was significantly associated with the risk of having anxiety [adjusted odds ratio (AOR)=4.896, P<0.015] and depression (AOR=5.335, P<0.012). Interpretation & conclusions Alcohol and tobacco are major substance abuse problems among coal mine workers. This population requires early community and primary care based brief intervention as well as additional community-based pharmacotherapy for substance dependence problems as well as intervention for common mental health issues.

Predictors of white matter hyperintensities in the elderly Congolese population.

White matter hyperintensities (WMHs) are strongly linked to cardiovascular risk factors and other health conditions such as Alzheimer's disease. However, there is a dearth of research on this topic in low-income countries and underserved populations, especially in the Democratic Republic of Congo (DRC) where the population is aging rapidly with increasing cardiovascular risk factors and dementia-related diseases. This study evaluates health factors associated with WMH in the elderly Sub-Saharan Africa (SSA), specifically Congolese adults. In a cross-sectional study of 77 people from the DRC, participants underwent neuroimaging to analyze WMH volume and completed clinical evaluation, laboratory-based blood exams, self-reported questionnaires, and interviews. A simple linear regression model was conducted to test the association between WMH and potential predictors (neurological status, age, sex, hypertension, diabetes, tobacco abuse, stroke, high cholesterol, cardiovascular medication, and alcohol abuse). Stepwise selection and backward elimination analyses were performed to obtain the final model. Finally, a multiple linear regression model was conducted to assess the association between WMH and variables retained in the final model (neurological status, sex, and age). Of the 77 individuals, 47 (61%) had dementia, 40 (52.6%) were males, and the mean age was 73 years (± 8.0 years standard deviation). In simple linear regression models, WMH was significantly associated with dementia (expβ1=1.75, 95% CI=1.14 - 2.71, p-value=0.01) though it had a weak association with age (expβ1=1.03, 95% CI=1.00 - 1.05, p-value=0.05) and sex (male) (expβ1=0.66, 95% CI=0.43 - 1.01, p-value=0.05). In multiple linear regression models, WMH was statistically significantly associated with dementia (expβ1=1.97, 95% CI=1.31 - 2.95, p-value =0.001), male sex (expβ2=0.54, 95% CI=0.36 - 0.80, p-value=0.003), and age (expβ3=1.03, 95% CI=1.00 - 1.06, p-value=0.03). However, WMH was not significantly associated with common cardiovascular risk factors, such as high blood pressure, diabetes, tobacco use, obesity, and high cholesterol levels. WMH is significantly associated with neurological status, sex, and age in the Congolese population. Understanding these predictors may improve our ability to diagnose, assess, and develop preventative treatments for white matter disease in SSA/DRC populations, where neuroimaging is difficult to obtain.

Influence of Rurality on Oral Cancer Trends among Organisation for Economic Co-Operation and Development (OECD) Member Countries-A Scoping Review.

Oral cancer is the general term used to describe cancers of the oral cavity and oropharyngeal region. These cancers are one of the leading causes of death in elderly residents within the Organisation for Economic Co-operation and Development (OECD) member countries in the 21st century. This scoping review was carried out to assess the influence of rurality on oral cancer trends and patterns among OECD member countries. Four online databases (Medline, PubMed, Scopus, and CINAHL) were searched for studies that reported on oral cancer trends in rural and remote areas in OECD member countries. A total of 1143 articles were obtained initially; among them, 995 papers were screened to include 18 articles for this scoping review. Studies have reported increasing incidence and prevalence in the United States, Australia, Canada, and European countries wherein risk factors such as tobacco, alcohol, and human papilloma virus (HPV) infections were associated with oral and oropharyngeal cancers. Awareness among people living in rural areas about HPV-related cancers was very low, while rates of tobacco and alcohol abuse were noted to be rising more rapidly than among their urban counterparts. Furthermore, the ageing population was most affected compared to the younger age groups of people with oral and oropharyngeal cancer that are prevalent in these regions. Overall, despite living in developed countries, rurality was noted to be a significant factor in the lower life expectancy of oral cancer patients, mainly due to the limited accessibility to tertiary cancer care centres and advanced medical care.

The impact of public health policies on reducing tobacco and substance abuse among the community

Public health policies have significantly impacted the reduction of tobacco and substance abuse within communities. Legislative measures, including increased taxation on tobacco products, comprehensive smoking bans, and restrictions on advertising, have been instrumental in decreasing smoking rates and protecting non-smokers from second-hand smoke. Community-based interventions, such as school-based programs and peer-led initiatives, address the root causes of substance abuse by promoting education, social support, and healthy behaviors, tailored to meet the specific needs of local populations, ensuring their relevance and effectiveness. Public awareness campaigns leveraging mass media and educational efforts play a crucial role in changing social norms and attitudes towards tobacco and substance use. Campaigns like the "truth" campaign and programs such as life skills training (LST) have shown significant success in reducing smoking and substance use among adolescents and young adults. Integrating these campaigns with other strategies enhances their impact, creating a comprehensive approach to public health. A multifaceted strategy combining legislative action, community engagement, and public education is crucial for achieving sustained reductions in tobacco and substance abuse. Continued investment in these areas is necessary to address evolving challenges and ensure long-term public health benefits. Coordinated efforts involving diverse stakeholders, including policymakers, educators, healthcare providers, and community organizations, are essential for effectively combating tobacco and substance abuse. By fostering collaboration and leveraging local resources, communities can create supportive environments that discourage harmful behaviors and promote healthier lifestyles. These comprehensive strategies demonstrate that a well-rounded approach, incorporating legislative measures, community-based interventions, and public awareness campaigns, is effective in mitigating the prevalence of tobacco and substance abuse, ultimately contributing to improved public health outcomes.

AB-free kava enhances resilience against the adverse health effects of tobacco smoke in mice.

Tobacco smoke remains a serious global issue, resulting in serious health complications, contributing to the onsets of numerous preventive diseases, and imposing significant financial burdens. Despite regulatory policies and cessation measures aimed at curbing its usage, novel interventions are urgently needed for effective damage reduction. Our preclinical and pilot clinical studies showed that AB-free kava has the potential to reduce tobacco smoke-induced lung cancer risk, mitigate tobacco dependence, and reduce tobacco use. To understand the scope of its benefits in damage reduction and potential limitations, this study evaluated the effects of AB-free kava on a panel of health indicators in mice exposed to 2 - 4 weeks of daily tobacco smoke exposure. Our comprehensive assessments included global transcriptional profiling of the lung and liver tissues, analysis of lung inflammation, evaluation of lung function, exploration of tobacco nicotine withdrawal, and characterization of the causal PKA signaling pathway. As expected, Tobacco smoke exposure perturbed a wide range of biological processes and compromised multiple functions in mice. Remarkably, AB-free kava demonstrated the ability to globally mitigate tobacco smoke-induced deficits at the molecular and functional levels with promising safety profiles, offering a unique promise to mitigate tobacco smoke-related health damages. Further pre-clinical evaluation and clinical translation are warranted to fully harness the potential of AB-free kava in combating tobacco smoke-related harms.

Nicotine and fluoxetine alter adolescent dopamine-mediated behaviors via 5-HT1A receptor activation.

Abuse or misuse of tobacco, e-cigarettes, or antidepressants may have serious clinical consequences during adolescence, a sensitive period during brain development when the distinct neurobiology of adolescent serotonin (5-HT) and dopamine (DA) systems create unique behavioral vulnerabilities to drugs of abuse. Using a pharmacological approach, we modeled the behavioral and neurochemical effects of subchronic (4-day) nicotine (60µg/kg, i.v.) or fluoxetine (1mg/kg, i.v.) exposure in adolescent and adult male rats. Nicotine and fluoxetine significantly enhance quinpirole-induced locomotor activity and initial cocaine self-administration in adolescents, but not adults. These effects were blocked by serotonin 5-HT1A receptor antagonists, WAY-100,635 (100 µg/kg, i.v.) or S-15535 (300 µg/kg, i.v.). Neurochemical and anatomical autoradiographic analysis of 8-OH-DPAT-stimulated [35S]GTPγS reveal that prior exposure to nicotine and fluoxetine results in both overlapping and distinct effects on regional 5-HT1A receptor activity. Both fluoxetine and nicotine enhance adolescent 5-HT1A receptor activity in the primary motor cortex (M1), whereas fluoxetine alone targets prefrontal cortical neurocircuitry and nicotine alone targets the amygdala. Given their different pharmacological profiles, comparison between WAY-100,635 and S-15535 indicates that postsynaptic 5-HT1A receptors mediate the behavioral effects of prior nicotine and fluoxetine exposure. In addition, within the adolescent M1, maladaptive changes in 5-HT signaling and 5-HT1A activity after nicotine or fluoxetine exposure may potentiate hyper-responsiveness to dopaminergic drugs and prime adolescent vulnerability for future substance abuse.

Aspartate-β-hydroxylase and hypoxia marker expression in head and neck carcinomas: implications for HPV-associated tumors

BackgroundA proportion of head and neck carcinomas (HNSCCs) are induced by high-risk human papillomaviruses (HPVs) and are associated with better patient outcomes compared to patients with HNSCCs related to tobacco and alcohol abuse. In the microenvironment of solid tumors, including HNSCCs, oxygen levels are often reduced, and a hypoxic state is induced. This can lead to a poor treatment response and a worse patient prognosis. One of the hypoxia-responsive genes is aspartate-β-hydroxylase (ASPH), whose activity promotes the growth, invasiveness, and metastasis of many types of solid tumors.MethodsIn our study, HNSCC samples were analyzed for the expression of ASPH and selected endogenous hypoxia markers by real-time PCR and/or multiplex fluorescence immunohistochemistry.ResultsExcept for the EPAS1 gene, which had higher mRNA expression in the HPV-negative group of HNSCC (p < 0.05), we found no other differences in the expression of the tested genes that were related to HPV status. On the contrary, a statistically significantly higher number of cells producing ASPH (p < 0.0001), HIF1A (p < 0.0001), GLUT1 (p < 0.0001), and MMP13 (p < 0.05) proteins were detected in the HPV-positive tumor group than in the HPV-negative sample group. All the evaluated markers, except for MMP9/13, were more abundant in the tumor parenchyma than in the tumor stroma. The Cox proportional hazard models showed that increased numbers of cells with GLUT1 and HIF1A protein expression were positive prognostic markers for overall and disease-specific survival in patients independent of HPV tumor status.ConclusionThe study examined HNSCC samples and found that elevated ASPH and hypoxia marker proteins, typically associated with poor prognosis, may actually indicate active HPV infection, the strongest prognostic factor in HNSCC patients. In cases where HPV status is uncertain, increased expression of HIF1A and GLUT1 can serve as positive prognostic factors.

Interventions for Tobacco Prevention and Control in Humanitarian Settings: A Scoping Review.

Tobacco usage is an epidemic as statistics point towards smoking as the second leading cause of death. Populations experiencing humanitarian emergencies may experience a higher propensity for tobacco, alcohol, and other substance abuse disorders. This review aimed to map tobacco prevention and control interventions in humanitarian settings. The search for this scoping review was conducted in six databases and supplemented with a gray literature search. Articles were screened at title-abstract and full-text by two pairs of authors, and data was abstracted by three individuals independently. An adapted diffusion of governance framework is used to discuss the findings. A total of 26 articles were included from the searches conducted in the databases and grey literature. The interventions targeted all age groups. The documents retrieved from the grey literature search were classified as population-based interventions, as they were not restricted to a particular group of individuals. Interventions were delivered at various locations, using different methods and engaging multiple stakeholders. Interventions assessed were grouped into packaging, labeling, and other policy interventions (pricing and taxes). There are few tobacco prevention and control interventions in the humanitarian context. The diffusion of governance perspective in implementing these interventions in humanitarian settings provides a cue for inter-sectoral cooperation among different stakeholders and disciplines beyond the health sector. Our review recommends exploring complementarity between the demand and supply side interventions for tobacco control. The scoping review has highlighted various tobacco prevention and control efforts in humanitarian settings. The interventions were delivered using various modes, and yet the burden of smoking is higher among the humanitarian population. Further research may use impact evaluation techniques to assess the impact of these interventions to facilitate the re-design of the implementation approach and policy priorities.

INTEGRATED APPROACH TO YOUTH MENTAL HEALTH

This study aimed to analyze the mental health issues among students at the National University “Yuriy Kondratyuk Poltava Polytechnic”, taking into account the international experiences in implementing psychosocial diagnostic programs. Based on this analysis, recommendations were formulated for the effective implementation of programs aimed at enhancing the mental well-being of the Ukrainian student community. Materials and Methods: A total of 812 students from various specialties at Yuriy Kondratyuk Poltava Polytechnic National University participated in the study. The age range of the participants was between 18 and 22 years old, with 47% (382 individuals) being male and 53% (430 individuals) female, ensuring gender balance in the sample distribution and representing a diverse cross-section of respondents. The survey was conducted anonymously using a Google form, thereby upholding the principle of confidentiality in psychological research. Result and discussion. The survey revealed a correlation between military operations and an escalation in anxiety disorders among civilians and refugees within the Ukrainian context. However, there remains an incomplete understanding of the mental well-being of the youth demographic. Presently, numerous studies indicate a decline in the psycho-emotional state of Ukrainian students. A significant proportion of respondents reported feelings of depression, nervousness, loneliness, and anger, with an uptick in cases involving alcohol, tobacco, and sedative abuse. An investigation into the mental health of women within educational institutions, including female students and teachers, unveiled heightened levels of fear and diminished resilience to stressful situations. This methodological approach facilitated the organization of information, enabling an objective comprehension of the issue and the formulation of specific recommendations for future action. Notably, there is a pressing need to implement programs aimed at enhancing both mental and physical health. Initiatives incorporating physical activity, balanced nutrition, and relaxation techniques have demonstrated potential in reducing stress levels and fostering improved mental well-being among students. Conclusions: The proposed recommendations are geared towards enhancing mental health standards and mitigating the impact of psychological challenges on academic performance, social integration, and overall life satisfaction.

Morphological and clinical findings in placentas and newborns with a history of tobacco, alcohol, and other substance abuse during pregnancy.

Exposure to toxins during pregnancy is the main modifiable behavior that affects the placenta and, consequently, the fetus. In particular, smoking is a recognized risk factor for negative outcomes. Our study pretended to examine gross and microscopic placental features in women who reported exposure to tobacco, alcohol, or other psychoactive substances. In this observational case-control study, we collected 706 placentas to assess precise substance exposure histological-interaction features of in the placenta. We examined gross and microscopic placental features, and then recorded maternal and newborn clinical conditions. We found that 4.8% of mothers admitted to consumption of some type of (harmful) substance. The most common pre-existing maternal condition was obesity (20.3%); predominant complications included amniotic infection (32.3%), urinary tract infection (14.5%) and hypertensive disorders of pregnancy (14.5%). In newborns, we discovered positive associations as respiratory distress syndrome. Macroscopically, exposed mothers had heavier placentas, more true knots, and single umbilical artery; microscopically, they were more likely to exhibit fetal vascular malperfusion (FVM). Until our present study, no research linked umbilical cord defects to toxic substance exposure; our study results do confirm association with adverse outcomes in neonates and alterations in the neuro-cardio-placental circuit through FVM. The results are confirming the importance of this modifiable risk factor and how its presence may potentially affect the course of pregnancy, as well as the health of both mother and child.

A Study of Histological and Clinical Parameters and Their Correlation With Lymph Node Metastasis and Two-Year Survival in 50 Cases of Oral Squamous Cell Carcinoma.

Oral squamous cell carcinoma (OSCC)is one of the most prevalent malignant neoplasms in South Asia and a major public health problem in India. The purpose of the study was to identify correlations among various clinicopathological parameters of OSCC in a tertiary care center in the Eastern Uttar Pradesh population of North India.The study is imperative due to the scarcity of available data from this region. A retrospective observational study was conducted on the cases received in the Department of Pathology over the period of January 2021 to December 2021. The study analyzed cases of OSCC, focusing on various factors such as age, gender, habits, tumor site, tumor size, differentiation, tumor-stroma ratio, tumor-infiltrating lymphocytes, tumor budding, worst pattern of invasion, depth of invasion, perineural invasion, lymphovascular invasion, underlying bone and overlying skin involvement, regional lymph node metastasis, and overall two-year survival. The mean age of the patients was 47.80 ± 12.48 years, and the male-to-female ratio was 15.6:1. Buccal mucosa was the most frequently affected site followed by the tongue. Fifty-six percent of cases reported with a history of tobacco abuse. Thirty-six percent of the patients had regional lymph node metastasis and exhibited a strong association with younger age, substance abuse, higher tumor size, tongue as a site, moderate-to-poor tumor differentiation, low tumor-infiltrating lymphocytes, and higher perineural and lymphovascular invasion. Moreover, at the end of the two-year survival analysis, 34% of patients succumbed to the disease. Overall survival was observed to be significantly better with <2 cm maximum tumor size, well-differentiated tumor morphology, higher tumor-infiltrating lymphocytes, and no nodal metastasis. The study highlights the intricate correlations of various histopathological factors in OSCC, shedding light on their potential implications for prognosis.

Role of Platelet Indices for Cardiovascular Risk Assessment in Premenopausal Females with Metabolic Syndrome

Objectives: The study aimed to estimate platelet indices in premenopausal females with metabolic syndrome (MetS) and the prevalence of individual risk factors of MetS and their association with platelet indices. Materials and Methods: It was a hospital-based, cross-sectional, and observational study conducted for a period of 3 months with the 130 premenopausal females with MetS. The collected data comprised clinical profile, hematological parameters, fasting blood glucose (FBG), serum creatinine, and lipid profile and were subjected to statistical analysis with P &lt; 0.05 as level of significance. Results: The mean age of the participants was 39.95 ± 3.44 years. Substance abuse of tobacco and alcohol was present in 9.23% and 5.37% of participants. Salt intake more than 5 g/day was confirmed by majority (86.15%). Waist circumference &gt;80 centimeters (cm) was noted in 64.61% of participants. Body mass index in range of 25–29.9 kilograms (kg)/m2 and 30–40 kg/m2 was observed in 36.92% and 60.77%, respectively. Diabetes mellitus (DM) and hypertension (HTN) had prevalence of 86.92% and 30% of participants, respectively. FBG ≥100 mg/dL was observed in 43.84% participants. The participants with DM, HTN, and hyperlipidemia showed the highest mean platelet volume (MPV) value. Patients with glycosylated hemoglobin (HbA1C) &gt;6.5% exhibited statistically significantly higher values of platelet distribution width, MPV, and platelet–large cell ratio. Platelet indices exhibited significant positive correlation with HbA1C, FBG, total cholesterol, triglyceride, and negative correlation with high-density lipoprotein. Conclusion: The present study highlighted the high prevalence of components associated with MetS, notably hyperglycemia, HTN, and obesity. The study also elucidated the substantial impact of DM, HTN, and hyperlipidemia on platelet indices.

IJCM_350A: Tobacco Abuse Among Adolescents in Shivamogga

Background: Tobacco and alcohol are very commonly used by the youth in urban and rural areas. NFHS-3 data shows that, among adolescents, 29% and 4% is the prevalence of tobacco use among males and females respectively. These numbers represent the overall usage of tobacco in some form, either cigarette, beedis or gutka. Studies have also shown a direct relationship between depression and prevalence of higher daily smoking rates. Objective: To estimate the prevalence of tobacco abuse among adolescents Methodology: A cross-sectional study was conducted among 700 adolescent boys and girls aged 16-19 years in rural and urban field areas of SIMS Shivamogga from August 2020 to September 2020. A pre-tested semi structured questionnaire which included questions on demographic details and tobacco consumption was used to collect data. Data was entered into Microsoft Excel spread sheet. SPSS (Version 21) was used to perform statistical analysis. Results were expressed in terms of frequency and percentages. Results: The prevalence of smoking among urban and rural adolescents was 9.1% and 11.1% respectively. Pan masala was the most common form of smokeless tobacco used. Conclusion: The prevalence of tobacco use among adolescents in Shivamogga aligns consistently with findings observed in comparable studies conducted across various regions of India.

Preoperative Risk Factors for Periprosthetic Joint Infection: A Narrative Review of the Literature.

Periprosthetic joint infection (PJI) poses a challenging complication for many patients undergoing arthroplasty, and the literature identifies numerous risk factors. A comprehensive understanding of the primary risk and protective factors for PJI is valuable for surgeons. This article aims to compile and summarize the key risk factors for PJI documented in the literature. Some risk factors are related to the nutritional status of patients, with obesity, weight loss, hypovitaminosis, and malnutrition being frequently reported. Pathologies affecting patients also contribute to PJI risk, including septic arthritis, hepatitis, diabetes, urinary tract infections, anemia, hypothyroidism, osteoporosis, and dental pathologies. Unhealthy habits, such as tobacco and drug abuse, are significant factors. Previous corticosteroid injections may also play a role in infection development. A few protective factors are also reported in the literature (use of statins, preoperative decolonization, and preadmission skin preparation). The identification of risk factors and the implementation of evidence-based preoperative protocols are essential steps in reducing the incidence of PJI.

Smoking-Related Disease Impact in the Eastern Mediterranean Region: A Comprehensive Assessment Using Global Burden of Disease Data.

Smoking remains a significant risk factor for numerous health issues, including lung cancer, chronic obstructive pulmonary disease, ischemic heart disease, stroke, and respiratory infections. This study investigates the burden of tobacco-related diseases in the Middle East and North Africa (MENA) region. Utilizing the GBD data, we examined the risk of smoking and second-hand smoke exposure and their related causes of death and disability in the 22 MENA countries. Smoking prevalence and disease burden data were analyzed with estimates reported as age-standardized rates. Tobacco abuse accounted for 14.5% of all deaths and 23.2% of deaths tied to known risk factors, with an age-standardized death rate of 110.8 per 100,000. Cardiovascular diseases were the primary cause of smoking-related deaths and DALYs, representing 53.4% of all deaths and 50.3% of all DALYs. This was followed by neoplasms (24.6% of all deaths and 20.3% of all DALYs), chronic respiratory diseases(12.4% of all deaths and 11.9% of all DALYs), and respiratory infections and tuberculosis(4% of all deaths and 3.4% of all DALYs). Second-hand smoking caused 20.5% of tobacco-related deaths and 21.5% of tobacco-related DALYs, disproportionately affecting younger individuals. An increasing disease burden was observed in Lebanon, Turkey, Syria, Tunisia, UAE, and Libya, and declining rates were most evident in Oman and Qatar. Our study emphasizes the impact of smoking on cardiovascular disease, the primary cause of smoking-related mortality and morbidity in the MENA region. Our findings highlight the urgent need for effective tobacco control policies and interventions.

Nicotine Motivated Behavior in C. elegans.

To maximize the advantages offered by Caenorhabditis elegans as a high-throughput (HTP) model for nicotine dependence studies, utilizing its well-defined neuroconnectome as a robust platform, and to unravel the genetic basis of nicotine-motivated behaviors, we established the nicotine conditioned cue preference (CCP) paradigm. Nicotine CCP enables the assessment of nicotine preference and seeking, revealing a parallel to fundamental aspects of nicotine-dependent behaviors observed in mammals. We demonstrated that nicotine-elicited cue preference in worms is mediated by nicotinic acetylcholine receptors and requires dopamine for CCP development. Subsequently, we pinpointed nAChR subunits associated with nicotine preference and validated human GWAS candidates linked to nicotine dependence involved in nAChRs. Functional validation involves assessing the loss-of-function strain of the CACNA2D3 ortholog and the knock-out (KO) strain of the CACNA2D2 ortholog, closely related to CACNA2D3 and sharing human smoking phenotypes. Our orthogonal approach substantiates the functional conservation of the α2δ subunit of the calcium channel in nicotine-motivated behavior. Nicotine CCP in C. elegans serves as a potent affirmation of the cross-species functional relevance of GWAS candidate genes involved in nicotine seeking associated with tobacco abuse, providing a streamlined yet comprehensive system for investigating intricate behavioral paradigms within a simplified and reliable framework.
