RESUMEN
Fluoride exposure is a global public health concern. Understanding the knowledge, attitudes, and practices (KAP) of affected populations is essential for effective community management. This study aimed to develop and validate a KAP questionnaire to assess fluoride and its risk in general population. An extensive literature review and focus group discussions were conducted to construct the questionnaire. Content validity was assessed using the Content Validity Index (CVI) based on expert feedback. Factor analysis was performed for final tool validation, and item characteristics were analyzed using IBM SPSS v. 27 and IBM AMOS v. 26. A total of 300 responses were collected. Initially, 41 items were included in the questionnaire, which were reduced to 25 after expert review. The final version included 19 items, with an I-CVI ranging from 0.80 to 1.00, indicating no issues with item difficulty or discrimination. Cronbach's alpha ranged from 0.88 to 0.90, demonstrating good internal consistency. The Kaiser-Meyer-Olkin (KMO) value was 0.848, and Bartlett's test (χ2 = 6860.978, df = 156, p < 0.01) confirmed data suitability for factor analysis. Three constructs were extracted with factor loadings greater than 0.5. Confirmatory factor analysis demonstrated a good model fit. This study developed and validated a robust 19-item KAP questionnaire for assessing knowledge, attitudes, and practices related to fluoride exposure. The tool demonstrated excellent reliability, validity, and internal consistency, supporting its use in guiding effective community-level management and public health interventions in fluoride-endemic areas.
RESUMEN
AIM: This review presents specific insights on the molecular underpinnings of the connection between fluorosis, type 2 diabetes, and microvascular complications, along with the novel biomarkers that are available for early detection. SUMMARY: Fluoride is an essential trace element for the mineralization of teeth and bones in humans. Exposure to higher concentrations of fluoride has harmful effects that significantly outweigh its advantageous ones. Dental fluorosis and skeletal fluorosis are the common side effects of exposure to fluoride, which affect millions of individuals globally. Alongside, it also causes non-skeletal fluorosis, which affects the population suffering from non-communicable diseases like diabetes by impacting the soft tissues and causing diabetic microvascular complications. Previous studies reported the prevalence range of these diabetic complications of neuropathy (3-65â¯%), nephropathy (1-63â¯%), and retinopathy (2-33â¯%). Fluoride contributes to the development of these complications by causing oxidative stress, cellular damage, degrading the functioning capability of mitochondria, and thickening the retinal vein basement. CONCLUSION: Early diagnosis is a prompt way of prevention, and for that, biomarkers have emerged as an innovative and useful technique. This allows healthcare practitioners and policymakers in endemic areas to comprehend the molecular complexities involved in the advancement of diabetic microvascular problems in the context of high fluoride exposure.
RESUMEN
Background: The coronavirus disease 2019 (COVID-19) pandemic outbreak created a challenge to manage the health, especially the mental health of various care providers involved in treating the patients infected with the virus. Previously published literature has shown a significant effect of the pandemic on the psychological health of healthcare workers (HCWs) globally; so, this study aimed to describe the psychological health outcomes of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection among Indian HCWs. Methods: An extensive literature search was conducted in databases including PubMed and Google Scholar. The search was restricted from the COVID-19 outbreak until June 2022. Cross-sectional studies and other studies (telephonic interviews and survey-based studies) reported the prevalence of anxiety and depression among frontline HCWs since the onset of the COVID-19 pandemic. All the studies were critically evaluated by two individual authors in terms of screening and methodological quality evaluation. A total of 16 studies were included in the final meta-analysis. Results: The prevalence of depression among n = 12231 participants of 14 studies was 0.37 CI 95% [0.28-0.48]; the prevalence of anxiety among n = 9467 participants of 12 studies was 0.39 CI 95% [0.29-0.49]. The results of the overall meta-analysis indicate that 37% and 39% of HCWs in this study experienced mild-to-severe depression and anxiety, respectively. During the COVID-19 pandemic, a significant number of HCWs developed mental health issues, with a reported prevalence of depression (37%) and anxiety (39%). Conclusion: Frontline HCWs' mental health should get full consideration during public health emergencies, screening should be actively conducted, and specific steps should be taken to lower the fear associated with the risk of infections.
