Association of Stathmin (Op18) with TNM Staging and Grading of Oral Squamous Cell Carcinoma and Its Role in Tumor Progression.

AIM: The purpose of the study was to evaluate the expression of stathmin in different histological grades and tumor, node, metastasis (TNM) staging of Oral carcinoma and various grades of oral dysplasia. The study also aims at observing the stathmin expression with respect to lymph node metastasis. MATERIALS AND METHODS: A total of 90 histopathologically confirmed tissue sections were acquired, of which 30 sections of oral dysplasia, 30 oral squamous cell carcinoma (OSCC) and 30 normal tissue sections were stained immunohistochemically with stathmin. The tissue sections, were categorized into different grades of oral dysplasia and OSCC based on histopathological examination. For estimation of stathmin expression, manual examination of 300 cells was done in a minimum of five different areas of tissue section and a mean proportion of positive-stained cells were determined. The statistical analysis of the results was done using ANOVA test. RESULTS: A statistically significant increase in mean staining scores of stathmin in OSCC group compared to dysplasia and control groups. A statistically significant difference was observed in different grades of dysplasia and OSCC groups. Stage III and stage IV OSCC tissue sections showed high intensity staining scores of stathmin expression. CONCLUSION: An increased expression of stathmin was detected in various grades of OSCC and also with respect to staging of oral cancer. Half the cases of OSCC with lymph node metastasis showed high intensity scores of stathmin. Based on the above facts, stathmin expression was indicated as a potential tool for predicting the outcome of oral cancer patients with lymph node metastasis and its expression was increased in the group with poor prognosis. CLINICAL SIGNIFICANCE: Any damage/mutation to stathmin can result in defects in cell division resulting in aneuploidy and in turn cancers. In this study, the results showed that there is a differential expression of stathmin in the early and the advanced grades and different TNM stages of OSCC. A high expression of stathmin was observed in all the cases with lymph node metastasis. These observations prove that stathmin has an important role in the progression, tumorigenicity, and prognosis of the oral cancer.

Assessment of Qol among COVID-19 Patients in South India: A Tertiary Care Center Study: An Original Research.

Introduction: The COVID-19 epidemic has brought about an unparalleled health disaster and fundamentally altered people's livelihoods. We intended to examine risk variables for "Health-Related Quality Of Life (HRQoL)" amid COVID-19 hospital discharged patients. Materials and Techniques: For this cross-sectional study, 1000 discharged patients who tested positive at the tertiary care center before January 2022 were included. The HRQoL was measured using a 5-level EuroQoL survey. The complete health state was evaluated using an Indian value set. The correlation of HRQoL and the clinical, sociodemographic parameters were investigated using appropriate statistical tools. Finally, regression model was utilized to identify all factors that predict the HRQoL dimensions. Results: It was found that 55% of patients said they had moderate or serious health issues. Forty percent of respondents said they had felt moderate-to-severe pain or discomfort, compared to 41% who said they had anxiety or sadness. The outcome of the logistic regression demonstrated the substantial influencers were "age, gender, occupation, location of care, heart conditions, and diabetes" on several HRQoL aspects. Conclusion: The COVID-19 dramatically worsens the patients' physical and mental health conditions. Therefore, the government and policymakers must develop comprehensive ways to lessen the patients' mental and physical health problems.

A Cross-Sectional Study: Are Myths on Cleft Lip and Palate Still Prevalent?

Background The etiology of cleft lip and palate (CL/P) remains largely unidentified. Evidence-based research shows a strong association with genetics, environmental factors, nutritional deficiency, smoking, alcohol, and drug misuse. Despite the increase in knowledge and widespread access to medical care beliefs contrary to science, folklores on CLP still occur in most developing countries. Methodology The study design was cross-sectional in nature and involved a sample of 136 parents of children with cleft lip and palate reporting to Smile Train Cleft Centers. It was conducted by using a self-structured questionnaire from December to March 2019. Results The highest recorded response was holding sharp objects, such as knives, scissors, or needles, during pregnancy (40.4%) and the least recorded response was for pregnant women going out on an auspicious day (3.7%). Conclusion The current study demonstrated that a majority of the parent's socioeconomic status was upper lower class. Some parents still believe in the myths around the etiology of CLP despite the advances in medicine and technology.

Sleep Quality in the Indian Adult Population During the COVID-19 Pandemic.

BACKGROUND: In response to the COVID-19 pandemic, social distancing measures such as stay-at-home orders were implemented for all non-essential workers. The consequent disruption in the defined daily work routine has impacted both the quality and duration of sleep. Our aim was to evaluate the quality of sleep in the Indian adult population during the COVID-19 pandemic. METHODS: The data were collected between April 17, 2020 and May 24, 2020, and participants were invited openly through social media platforms (Facebook, Twitter, WhatsApp, Instagram). Sleep quality was evaluated using the Pittsburgh Sleep Quality Index (PSQI) Questionnaire. RESULTS: The study population consisted of 808 participants (mean age 30.85 years, 56.7% female). The mean sleep score of the study population was 6.78 ± 3.19 on the PSQI, with a majority (57.2%) of respondents showing 'poor' sleep quality (>5 on PSQI). The mean sleep duration of the study population was found to be 6.9 ± 1.4 h, and sleep latency was 42.64 ± 51.6 min. The PSQI scores were comparable for age, gender, and work status and were not significant. However, a significant association between self-reported mental health and quality of sleep was found (p<0.05). Participants who reported a deterioration in mental health were more likely to have poor sleep quality than those who reported an improvement in their mental health. CONCLUSIONS: The results of this study show that poor sleep quality is widely prevalent among the the general population in India during the COVID-19 pandemic.
