ABSTRACT

Background: Portal hypertension commonly occurs due to liver cirrhosis, and esophageal varices (EV) is one of the major complications associated with it. The most common cause of death in liver cirrhosis is EV bleeding. Hence, GE screening for EV is required, which is an invasive procedure. Regular use of endoscopy results in low compliance due to cost and discomfort for patients. Hence, identifying non-invasive markers that could grade EV provides a useful screening tool for family physicians and primary health centers (PHCs) by referring the patient to higher centers for definitive treatment, which could reduce mortality due to variceal bleeding in cirrhotic patients. Aims: To assess non-invasive predictors of grade EV in patients diagnosed with liver cirrhosis. Settings and Design: Cross-sectional study. Methods and Material: A total of 109 patients with liver cirrhosis underwent clinical and biochemical evaluation, USG abdomen with spleen bipolar diameter, ascitic fluid analysis, and upper GE with a grade of EV are recorded. Statistical Analysis Used: SPSS software with Student t-test, Chi-square t-test, analysis of variance, receiver operator characteristic (ROC) curves, and Spearman correlation with 95% CI is used. P <0.05 is considered significant. Results: Aminotransferase to Platelet count Ratio Index (APRI) score >1.815, PC/SD ≤909, and SAAG >1.1g/dl showed EV in liver cirrhosis (P < 0.05). The order of prediction with ROC curves shows APRI score > PC/SD > SAAG. In grading EV, APRI scores of 1.9-2.5 and >2.5 showed small and large EV, respectively (P < 0.05). Conclusions: APRI score may be used in PHC as an early intervention to grade EV and refer the patient to higher centers for definitive treatment. This would prevent the progression of varices to rupture and reduce mortality due to variceal bleeds in liver cirrhosis patients.

ABSTRACT

The intestinal tract encompasses one of the largest mucosal surfaces with a well-structured layer of intestinal epithelial cells supported by a network of underlying lamina propria immune cells maintaining barrier integrity. The commensal microflora in this environment is a major contributor to such functional outcomes due to its prominent role in the production of secondary metabolites. Of the several known metabolites of gut microbial origin, such as Short Chain Fatty Acids (SCFAs), amino acid derivatives, etc., secondary bile acids (BAs) are also shown to exhibit pleiotropic effects maintaining gut homeostasis in addition to their canonical role in dietary lipid digestion. However, dysbiosis in the intestine causes an imbalance in microbial diversity, resulting in alterations in the functionally effective concentration of these secondary metabolites, including BAs. This often leads to aberrant activation of the underlying lamina propria immune cells and associated signaling pathways, causing intestinal inflammation. Sustained activation of these signaling pathways drives unregulated cell proliferation and, when coupled with genotoxic stress, promotes tumorigenesis. Here, we aimed to discuss the role of secondary metabolites along with BAs in maintaining immune-gut homeostasis and regulation of inflammation-driven tumorigenesis with emphasis on the classical Wnt/ß-Catenin signaling pathway in colon cancer.

ABSTRACT

BACKGROUND: Depression and alcohol use are common among people living with HIV (PLWH) and associated with adverse outcomes. However, there is a paucity of studies exploring trajectories of depressive symptom presence over time among alcohol consuming men PLWH. METHODS: Men PLWH were repeatedly assessed for depressive symptoms from baseline through 27 months using the 10-item Center for Epidemiologic Studies-Depression scale. Group-based trajectory modeling was used to identify trajectories of depressive symptoms over time among control (n = 188) and intervention participants (n = 564). Multinomial logistic regression was used to explore the relationship between trajectory subgroups and baseline independent variables. RESULTS: Among intervention participants, the three subgroups were characterized as 'low' (85.8 % of the participants), 'fluctuating' (8.7 %), and 'persistently increasing' symptoms (5.5 %). Similarly, three trajectory subgroups among control participants were labeled as: "low" (54.4 %); "fluctuating" (33.5 %) and "persistently increasing'" (12.1 %). Among intervention participants, longer duration since HIV diagnosis (aOR: 1.05, 95 % CI: 1.01-1.12) and HIV-related stigma (aOR: 1.09, 95 % CI: 1.02-1.18) were associated with persistently increasing depressive symptoms trajectory. Further, alcohol drinking problems (aOR: 1.10, 95 % CI: 1.04-1.17) was associated with fluctuating depressive symptoms trajectory. Among control participants, only lower overall self-rated health status was associated with persistently increasing depressive symptoms trajectory (aOR: 0.96, 95 % CI: 0.93-0.99). LIMITATIONS: Selection bias; Information bias; Lack of causal interference; Generalizability. CONCLUSION: Identifying subgroups of men PLWH with different depressive symptoms trajectories may inform effective and tailored intervention approaches to address mental health treatment and prevention among alcohol consuming men PLWH in India and elsewhere.

ABSTRACT

This study examined the hypothesis that HIV-related stigma mediates the effect of alcohol use on health-related quality of life (HRQoL) among alcohol consuming Indian men living with HIV (PLWH). The study used baseline data from a randomized controlled clinical trial entitled 'Alcohol and ART adherence: Assessment, Intervention, and Modeling in India. Participants completed surveys assessing demographic characteristics, alcohol use, HIV-related stigma, HRQoL. Mediation analysis was conducted to establish the mediation effect of HIV-related stigma on the relationship between alcohol use and HRQoL. The final mediation model showed that the effect of alcohol use on HRQoL were partially mediated by overall HIV-related stigma. Specially, 27.1% of the effects of alcohol use on HRQoL was mediated through overall HIV stigma. In the HIV stigma subdomain analyses, negative self-image mediated 14% and concerns with public attitudes (anticipated stigma) mediated 17.3% of the effect of alcohol use on HRQoL respectively. The findings suggest that efforts to reduce the negative impact of alcohol use on HRQoL and improve HRQoL among PLWH should include interventions addressing both alcohol use and specific forms of HIV-related stigma.


RESUMEN: Este estudio examinó la hipótesis de que el estigma relacionado con el VIH mediaría el efecto del consumo de alcohol en la calidad de vida relacionada con la salud entre hombres indios que consumen alcohol y viven con VIH. El estudio utilizó datos de línea base de un ensayo clínico aleatorizado controlado titulado "Consumo de alcohol y adherencia al TAR: evaluación, intervención y modelización en India". Los participantes completaron encuestas que evaluaron características demográficas, consumo de alcohol, estigma relacionado con el VIH y calidad de vida relacionada con la salud (CVRS). Se realizó un análisis de mediación para establecer el efecto de la mediación del estigma relacionado con el VIH en la relación entre el consumo de alcohol y la CVRS. El modelo final de mediación mostró que el efecto del consumo de alcohol en la CVRS fue parcialmente mediado por el estigma general relacionado con el VIH. Específicamente, el 27,1% de los efectos del consumo de alcohol en la CVRS se medió a través del estigma general relacionado con el VIH. En los análisis de subdominios del estigma del VIH, la imagen negativa de sí mismo medió el 14% y las preocupaciones sobre las actitudes públicas (estigma anticipado) mediaron el 17,3% del efecto del consumo de alcohol en la CVRS, respectivamente. Los resultados sugieren que los esfuerzos para reducir el impacto negativo del consumo de alcohol en la CVRS y mejorar la CVRS entre las personas que viven con VIH deberían incluir intervenciones que aborden tanto el consumo de alcohol como formas específicas de estigma relacionado con el VIH.

ABSTRACT

Heavy alcohol use is negatively affecting antiretroviral therapy adherence, mental health and health-related quality of life among people living with HIV (PLWH). This paper aims to test the mediation model examining whether changes in depression symptoms mediate in the relationship between health-related quality of life and alcohol use among male PLWH who consume alcohol in India. The study is guided by the stress-coping model, which posits that individuals facing stress may turn to maladaptive coping mechanisms such as alcohol use to alleviate their distress, which includes depression and a low health-related quality of life due to various physical, psychological, and social factors associated with the HIV infection. This study used the data from a randomized controlled clinical trial entitled 'Alcohol and ART adherence: Assessment, Intervention, and Modeling in India'. Participants completed surveys assessing demographic characteristics, health-related quality of life, depressive symptoms, and alcohol use. Multiple simple mediation models were investigated to examine whether changes in depression symptoms mediated the association between the changes in health-related quality of life and alcohol use after a 9-month follow-up. A total of 940 male PLWH were recruited and interviewed, with 564 participants in the intervention group and 376 participants in the control group. After a 9-month intervention, the mediation results showed that, among intervention participants, a decrease in depressiove symptoms mediated the relationship between improved health-related quality of life and lower alcohol use. However, among control participants, changes in depressive symptoms did not mediate the relationship between changes in health-related quality of life and alcohol use. The study findings have practical and theoretical implications. From a practical perspective, the results suggest that interventions aimed at simultaneously improving HRQoL and depressive symptoms among male PLWH with alcohol use may help reduce alcohol consumption. Therefore, interventions that address depressive symptoms in addition to improving HRQoL may have an even greater impact on reducing alcohol use among this population. Theoretically, the study supports the use of the stress-coping theory in understanding the association between HRQoL, mental health, and alcohol use among male PLWH, contributing to existing literature on a gap in our understanding of the interactions among these factors among PLWH.

ABSTRACT

BACKGROUND: The anti-tumor immune response plays a key role in colorectal cancer (CRC) progression and survival. The T cell-inflamed gene expression profile (GEP) is a biomarker predicting response to checkpoint inhibitor immunotherapy across immunogenic cancer types, but the prognostic value in CRC is unknown. We evaluated associations with disease-specific survival, somatic mutations, and examined its differentially expressed genes and pathways among 84 sporadic CRC patients from the Seattle Colon Cancer Family Registry. METHODS: Gene expression profiling was performed using Nanostring's nCounter PanCancer IO 360 panel. Somatic mutations were identified by a targeted DNA sequencing panel. RESULTS: The T cell-inflamed GEP was positively associated with tumor mutation burden and microsatellite instability high (MSI-H). Higher T cell-inflamed GEP had favorable CRC-specific survival (hazard ratio [HR] per standard deviation unit = 0.50, p = 0.004) regardless of hypermutation or MSI status. Analysis of recurrently mutated genes having at least 10 mutation carriers, suggested that the T cell-inflamed GEP is positively associated with RYR1, and negatively associated with APC. However, these associations were attenuated after adjusting for hypermutation or MSI status. We also found that expression of genes RPL23, EPCAM, AREG and ITGA6, and the Wnt signaling pathway was negatively associated with the T cell-inflamed GEP, which might indicate immune-inhibitory mechanisms. CONCLUSIONS: Our results show that the T cell-inflamed GEP is a prognostic biomarker in non-hypermutated microsatellite-stable CRC. This also suggests that patient stratification for immunotherapy within this CRC subgroup should be explored further. Moreover, reported immune-inhibitory gene expression signals may suggest targets for therapeutic combination with immunotherapy.

ABSTRACT

BACKGROUND: The depression, anxiety, and stress is a major educational problem among students all around the world. The purposes of this study were to determine the depression, anxiety, and stress among the high school adolescent children in public and private schools in Rangareddy district, Telangana state. MATERIALS AND METHODS: The present study was a cross-sectional study. The study sample considered 120 children from private schools and 259 children from public schools were studied. The study tool used was a questionnaire containing DASS (Depression, Anxiety, and Stress scale and sociodemographic characteristics. The data were expressed as proportion and mean values (Analysis of variance, independed t-test, and Pearson correlation) spatially tests were used at a significance level of P < 0.05). RESULTS: The overall prevalence of depression in children from the public school was found to be only 5%, that of anxiety was 20.8%, and that of stress was 15.8%; the overall prevalence of depression in children from private schools was found to be 1.9%, that of anxiety was 20.5%, and that of stress was 20.1%. CONCLUSION: In both schools, anxiety and atress were found to be more among study participants. Depression was observed to be less. But if they have more anxiety and stress and if not taken proper care at this point of time, it might get converted into a state of Depression.

ABSTRACT

The proportion of older adults is on the rise. Management of dental problems in this group is different from the general population, and hence requires special training. Gerodontology is yet to find its place in the Indian dental curriculum. A lack of training would result in inadequate care delivery. In this article, we share our views on the need for inclusion of the subject, potential challenges, and a guide for incorporation of gerodontology in undergraduate and postgraduate curriculum in the Indian dental institutes. We propose a framework based on the salient features of Kern's 6-step approach for curriculum development and Kotter's 8-step change management model. Some features are common to both the models. A combination of these models includes the following salient features: Problem identification and general needs assessment, beginning with a sense of urgency and targeted needs assessment, communication of the vision for change, working in guided coalitions and defining clear goals and objectives, adopting the relevant educational strategies, implementation strategies to enable change and generating short-term wins, evaluating the effectiveness of the curricular reform and sustaining and anchoring the change. The proposed framework may also be useful for countries where gerodontology is yet to be implemented.

ABSTRACT

Natural radioactivity is released into the environment during the combustion process of coal at various thermal power plants. Coal contains higher contents of α-emitting radionuclides such as 238U, 232Th along with their decay elements, which pose a potential health risk to the population. In the present studies, the effluent waste samples were collected from a coal fired Thermal Power Plant. Samples were collected in the form of solid residues and filtrates. CR-39 detector pieces were then exposed for varying time with residue and filtrate samples for registering the alpha tracks for α-detection and measurement. Thus, registered alpha particles in CR-39 detectors were revealed by employing the conventionally used 6M NaOH/KOH etchant and 5% tetraethyl ammonium bromide (TEAB) as a phase transfer catalyst in 6M NaOH/KOH etchant. Under both compositions of the etchants, CR-39 detectors were etched at 60 °C for 6 h for developing alpha tracks for observations under optical transmission microscope. Alpha track densities (Td) and alpha track diameters in the etched CR-39 detectors for all samples were measured. The introduction of new chemical etchant effectively improved the uniformity in distribution of alpha tracks, enhanced the track density, and reduced the time of track revelation in CR-39 detectors. Therefore, it could be concluded that the phase transfer catalyst TEAB was highly effective in the etchant for alpha track revelation and detection as compared to conventionally used 6M NaOH etching method. Apart from measuring alpha radio activities, the amounts of 238U & 232Th in the samples were also measured by ICP-MS for understanding the alpha radio activities measured in the coal samples.

ABSTRACT

PURPOSE/OBJECTIVES: To investigate dental students' perceptions and concerns regarding the COVID-19 pandemic, their coping strategies and support resources, and their perceived stress levels. METHODS: A customized 19-item survey and the perceived stress scale (PSS) were applied to undergraduate dental students from the US, Spain, Ireland, Chile, India, and Brazil between April 10 and July 5, 2020. Linear modeling and mediation analysis were used to explore the relationships among demographics, stressors, coping mechanisms, social support, and stress RESULTS: A total of 4475 students responded to the survey. The majority (72.4%) were women, and 52.3% had no COVID-19 training at the time of the survey. The students reported that they had to accommodate to changes in patient care (96.6%) and didactic learning (95.2%) activities, while 88.5% of the respondents indicated at least one of their courses moved online. Transition to online courses went "smoothly with some troubles" for 51.8% of the respondents, and 48.3% perceived the faculty as prepared for the online transition; however, 45.9% reported feeling extremely concerned about the impact of COVID-19 on their education. The average PSS score was 21.9 of 40 (moderate stress). Multivariate models were built for participants with full data (n = 3899). Being male, having completed more dental coursework, and perceiving a smoother transition were associated with lower PSS scores; more concern about academic progress was associated with higher PSS. Faculty support mediated the relationship between a smoothness of transition and concern about academic progress and PSS scores CONCLUSION: Stress caused by the pandemic may be alleviated by smoother transition and good faculty support.

ABSTRACT

Cancer is a complicated long-term disease due to computable key molecular players involved in aggravating the disease. Among various kinds of cancer, hepatocellular carcinoma (HCC) is the ninth leading cause of cancer. Recently, plant-based products are gaining a lot of attention in the field of research because of their anti-tumor properties. In our previous study, we reported based on in-silico method that bromelain, a cysteine protease extracted from the stem of the pineapple, has high binding affinity with the transcription factors p53 and ß-catenin proteins which are key players in controlling the progression of hepatocellular carcinoma. Bromelain, isolated mainly from the stem of Pineapple (Ananas comosus), belongs to the family Bromeliaceae. The present study deals with preclinical analysis of bromelain as an anti-cancer agent and its intracellular effect on the expression of p53 and ß-catenin protein. Our study reports cytotoxic activity, cell proliferation, migration, invasion, arrest in the S-phase, and G2/M phase in cell cycle analysis by treating with bromelain in HepG2 cell lines. We also report up-regulation of p53 protein by drug-induced impediment leading to apoptotic process in HepG2 cells and down-regulation of ß-catenin protein in HepG2 cells which interferes in ß-catenin/TCF-DNA interaction further, down-regulating Wnt genes and suppressing the canonical pathway. Finally, we conclude that bromelain inhibits tumorigenic potential in HepG2 cell lines.

ABSTRACT

Increasing life expectancy, concepts of patient well-being, and the multiplicity of needs of the geriatric population, demand contribution, and collaboration of physicians, dentists, psychologists, pharmacists, and other allied health disciplines, to provide quality care to patients. Interprofessional education (IPE) is an approach to education that improves collaboration among health professionals and it can aid in better management of geriatric patients. Communication and cooperation affect health care performance and hence, influence patient outcomes. Currently, each of the disciplines mentioned has customized undergraduate and/or postgraduate training in geriatric care. Though a uni-disciplinary educational approach increases knowledge and skills of individual professions separately, IPE offers significant advantages. IPE seeks to have students learning together, as well as from each other to develop exemplary collaborative practice. The World Health Organization (WHO) has proposed that IPE will ensure optimum health care. However, IPE is yet to find its proper place in dental education. It would help dental students to develop a positive attitude toward geriatric patients and increase their empathy and efficiency in the management of these patients. This manuscript seeks to highlight the concept of interprofessional education (IPE) in gerodontology and develop recommendations for implementation of IPE in India.

ABSTRACT

We examined the association between alcohol consumption, adherence and viral load (VL) in a cohort of 940 alcohol-consuming, human immunodeficiency virus (HIV)-positive men receiving antiretroviral therapy in Mumbai. Some of the participants (16.7%) had missed >1 doses in the last four days and 17.6% reported >1 treatment interruptions in the last 12 months; 60.8% of the participants consumed alcohol >2 times/month, 62.8% consumed >3 drinks/typical day and 11.5% reported binge drinking >1 times/month; 76.4% of the participants had VL<200 copies/mL. Higher alcohol consumption was associated with nonadherence (odds ratio [OR]: 1.21; 95% confidence interval [CI]: 1.11-1.31) and treatment interruptions (OR: 1.20; 95% CI: 1.11-1.31). We found no association between alcohol use and VL. There was, however, a significant interaction effect of alcohol use and nonadherence on virological failure (Adjusted Odds Ratio [AOR]: 1.23; 95% CI: 1.03-1.47) implying that alcohol negatively impacts VL outcomes but mediated through adherence. Alcohol use was associated with poor adherence, which in turn was a strong predictor of virological failure.

ABSTRACT

PURPOSE: BRAF mutation and DNA hypermethylation have linked sessile serrated adenomas/polyps (SSA/Ps) to serrated colorectal cancer (CRC) in cross-sectional studies, but they have not been evaluated in a longitudinal study. We aimed to evaluate the associations between molecular markers of serrated polyps and subsequent advanced colorectal neoplasia. METHODS: Study subjects included Kaiser Permanente Washington members aged 20-75 years who received an index colonoscopy between 1/1/1998 and 12/31/2007 and had hyperplastic polyps (HPs) or SSA/Ps according to study pathology review. Polyps from index colonoscopies were removed and assayed for BRAF mutation, CpG island methylator phenotype (CIMP), and MLH1 methylation. Pathology reports and biopsies from the subsequent lower gastrointestinal endoscopy through 1/1/2013 were reviewed for advanced colorectal neoplasia. We identified additional incident CRC cases through linkage to the Seattle-Puget Sound Surveillance Epidemiology and End Results registry. We used generalized estimating equations to calculate adjusted odds ratios (OR) and 95% confidence intervals (CI) for subsequent advanced colorectal neoplasia, comparing index serrated polyps with different molecular markers. RESULTS: We included 553 individuals with index serrated polyps (420 HPs and 133 SSA/Ps) and 795 subsequent endoscopies. The prevalence of BRAF-mutant, CIMP-high, and MLH1-methylated serrated polyps were 51%, 4%, and 2%, respectively. BRAF and CIMP were not associated with subsequent advanced colorectal neoplasia. MLH1-methylated SSP/As were significantly more likely to have subsequent advanced neoplasia (OR = 4.66, 95% CI 1.06-20.51). CONCLUSION: Our results suggest that BRAF-mutant and CIMP-high serrated polyps are not associated with subsequent advanced colorectal neoplasia. Among SSA/Ps, MLH1 methylation may be an important marker to identify high-risk CRC precursors.

ABSTRACT

BACKGROUND: The current rise in the world's geriatric population has placed additional demands on dental professionals, as the management of geriatric patients requires distinct competencies. AIM: To review and perform a content analysis of the gerodontology undergraduate curriculum worldwide. DATA SOURCES: A search was carried out in PubMed, Web of Science, ERIC and EMBASE databases for the period-July 2008 till May 2019, using MeSH terms. A search for websites of Indian universities was also done, and undergraduate curricula were screened. STUDY ELIGIBILITY CRITERIA: The study included articles related to the undergraduate curriculum, which contained training in geriatric dentistry. Articles in foreign languages and those related to dental hygienists were excluded. RESULTS: A total of 218 articles were obtained, of which 19 met the inclusion criteria. A total of 301 colleges taught gerodontology. Amongst them, 50 colleges had a gerodontology department. Clinical training and outreach experience were provided in 175 and 73 colleges, respectively. There are no reports on the status of gerodontology in Asian countries (excluding Japan). In India, gerodontology is not taught as a separate subject. However, few gerodontology-related topics are covered in clinical subjects. CONCLUSIONS: There seems to be a wide variation in the content of gerodontology curriculum taught worldwide. Other than the European and American regions, gerodontology is yet to develop in other parts of the world. In India, a robust training programme is required to address the lack of dental care providers for the geriatric population using guidelines established by ECG and ADEA.

ABSTRACT

BACKGROUND AND AIM: Oral cancer is one of the most life-threatening conditions, early diagnosis of which greatly increases the probability of cure and survival rates. Knowledge regarding risk factors and early signs among the nonhealth professionals which help in early detection prevention and of the disease. Therefore, the aim of this study is to assess the awareness about tobacco use among nonhealth professional students in Bangalore city. METHODOLOGY: A cross-sectional descriptive questionnaire study was conducted to assess the knowledge and awareness about oral cancer among 800 nonhealth professional students in Bengaluru city. A self-administered questionnaire containing 26 questions pertaining to awareness, signs, symptoms and risk factors of tobacco use was administered to the students. RESULTS: The results revealed that the majority of the students (55.5%) were aware about oral cancer but have less knowledge in terms of its signs and symptoms of oral cancer. The main source for information pertaining to oral cancer was obtained from mass media, i.e., TV, radio and social media (21.5%). CONCLUSION: The study reveals that there is a need for education and raise awareness about oral cancer among nonhealth professional students.

ABSTRACT

BACKGROUND: Construction of appropriate test items is a challenge in preparing quality multiple choice questions. Item analysis provides valuable feedback data on validity of multiple choice questions. The present study was conducted to evaluate the difficulty index, discrimination index and distracter efficiency of the items present in the multiple choice questions of post graduate dental entrance examinations. METHODS: A list consisting of 20 MCQs was taken from the entrance exam books of MCQs on an introductory topic and administered to 104 undergraduate students. RESULTS: In the present study 15% of the MCQs related to impression making procedure were difficult with difficulty index (p) less than 30%, 15% were poor discriminators and 55% had at least one non-functional distracter. CONCLUSION: Item analysis of MCQs in post graduate entrance examinations demonstrated low difficulty index, discrimination index and distracter efficiency. Hence, we propose a strong need for faculty training in test constructors and their post validation.
