ANN: adversarial news net for robust fake news classification.

With easy access to social media platforms, spreading fake news has become a growing concern today. Classifying fake news is essential, as it can help prevent its negative impact on individuals and society. In this regard, an end-to-end framework for fake news detection is developed by utilizing the power of adversarial training to make the model more robust and resilient. The framework is named "ANN: Adversarial News Net," emoticons have been extracted from the datasets to understand their meanings concerning fake news. This information is then fed into the model, which helps to improve its performance in classifying fake news. The performance of the ANN framework is evaluated using four publicly available datasets, and it is found to outperform baseline methods and previous studies after adversarial training. Experiments show that Adversarial Training improved the performance by 2.1% over the Random Forest baseline and 2.4% over the BERT baseline method in terms of accuracy. The proposed framework can be used to detect fake news in real-time, thereby mitigating its harmful effects on society.

Increase in acute pancreatitis, especially gallstone related, as the cause for emergency admissions: Temporal trend from Kashmir, India.

BACKGROUND: The incidence of acute pancreatitis is increasing globally. Gallstones (GS) and ascariasis are the major causes for acute pancreatitis in the Kashmiri population. In recent years, we have observed an increase in the admission rate of acute pancreatitis. Many patients who present first time as gallstone pancreatitis have asymptomatic gallstones. We aimed at studying the etiology and yearly admission rate of acute pancreatitis with main focus on gallstone pancreatitis and the contribution of asymptomatic gallstones. METHODS: This was a hospital-based, prospective, observational study from January 2015 to December 2019 for a period of five years. Patients of acute pancreatitis were evaluated for etiology and yearly admission rate. Patients of gallstone pancreatitis were evaluated in terms of clinical profile, risk factors, nature (symptomatic/asymptomatic, known/unknown gallstones), size of stones, treatment and outcome in terms of severity and mortality. The data was analyzed by Statistical Package for the Social Sciences (SPSS) version 20.0, as mean (SD), frequencies and percentages. RESULTS: As many as 702 (8.5%) patients of acute pancreatitis were admitted among 8245 gastrointestinal emergencies in five years. The yearly admission rate of acute pancreatitis was 5.6%, 7.3%, 8.7%, 9.5% and 10.3%, respectively (p = 0.013). Gallstones, Ascariasis, alcohol and idiopathic acute pancreatitis were 47.7%, 6.9%, 1.2% and 33.7%, respectively. Gallstone pancreatitis increased from 31% in 2015 to 52.4% in 2019 (p = 0.045) and ascariasis-related acute pancreatitis declined from 14.4% to 1.6% (p = 0.034). Asymptomatic gallstones constituted 87.7% of cases. Known/unknown asymptomatic gallstones and symptomatic gallstones were 24.4%, 63.2% and 12.2%, respectively. Gallstones < 5 mm and > 5 mm were76.1% and 23.8% respectively (p = 0.027). Cholecystectomy rate in index admission was 4.7%. Mild, moderate and severe gallstone pancreatitis was 60.2%, 18.8% and 20.8%, respectively. Mortality in gallstone pancreatitis was 10.4%. CONCLUSION: The incidence of acute pancreatitis is increasing due to gallstone pancreatitis. Ascariasis-related acute pancreatitis has declined. There is significant contribution of asymptomatic gallstones in patients who present for the first time as acute pancreatitis. Small gallstones < 5 mm are likely to be the risk factors for gallstone pancreatitis.

Determinants of body weight changes during Ramadan fasting in India amid COVID-19: A cross-sectional study.

Ramadan intermittent fasting (RIF) presents unique challenges and opportunities for public health and clinical practice, especially in populations with a high prevalence of non-communicable diseases. This study aims to investigate the impact of RIF on weight change among Indian Muslims and explore the associated demographic, dietary, and behavioral factors. A cross-sectional survey was conducted with a sample of Indian Muslim adults who observed RIF. Participants were asked to report their demographic information, family and personal health history, and dietary and lifestyle behaviors before and during Ramadan month. The primary outcome was body weight change, with secondary outcomes including changes in dietary patterns, physical activity, and other health-related lifestyle behaviors. The study found that during Ramadan, nearly half of the participants (48.5%) self-reported a retained initial weight, while a significant fraction (30.9%) self-reported a modest weight reduction between 0.5 to 2.5 kg at the end of Ramadan. Additionally, self-reported eating practices demonstrated moderately altered by about half (48.4%) of the study participants, with 32.2% reporting minor changes and 8.2% indicating substantial changes. An urban residence was associated with a higher likelihood of weight gain, where urban residents showed 3 times the odds of increased weight compared to rural inhabitants. Employment status emerged as a significant determinant for weight fluctuation, influencing both weight gain and loss. During Ramadan, there was a significant rise in snacking frequency, increasing from 21.7% to 32.6% in comparison with pre-Ramadan. The consumption of large quantities of food more frequently grew from 14.9% to 36%, and the incidence of eating despite not being hungry went up from 17.4% to 33.2%. The study demonstrates that RIF is associated with variable changes in body weight among adult Indian Muslims, influenced by urbanization, employment status, and dietary changes. The findings suggest that clinicians should provide tailored advice about body weight regulation during Ramadan and consider integrating community-based health initiatives within religious settings to improve health outcomes.

Can Transcranial Electrical Stimulation Facilitate Post-stroke Cognitive Rehabilitation? A Systematic Review and Meta-Analysis.

Background: Non-invasive brain stimulation methods have been widely utilized in research settings to manipulate and understand the functioning of the human brain. In the last two decades, transcranial electrical stimulation (tES) has opened new doors for treating impairments caused by various neurological disorders. However, tES studies have shown inconsistent results in post-stroke cognitive rehabilitation, and there is no consensus on the effectiveness of tES devices in improving cognitive skills after the onset of stroke. Objectives: We aim to systematically investigate the efficacy of tES in improving post-stroke global cognition, attention, working memory, executive functions, visual neglect, and verbal fluency. Furthermore, we aim to provide a pathway to an effective use of stimulation paradigms in future studies. Methods: Preferred reporting items for systematic reviews and meta-analysis (PRISMA) guidelines were followed. Randomized controlled trials (RCTs) were systematically searched in four different databases, including Medline, Embase, Pubmed, and PsychInfo. Studies utilizing any tES methods published in English were considered for inclusion. Standardized mean difference (SMD) for each cognitive domain was used as the primary outcome measure. Results: The meta-analysis includes 19 studies assessing at least one of the six cognitive domains. Five RCTs studying global cognition, three assessing visual neglect, five evaluating working memory, three assessing attention, and nine studies focusing on aphasia were included for meta-analysis. As informed by the quantitative analysis of the included studies, the results favor the efficacy of tES in acute improvement in aphasic deficits (SMD = 0.34, CI = 0.02-0.67, p = 0.04) and attention deficits (SMD = 0.59, CI = -0.05-1.22, p = 0.07), however, no improvement was observed in any other cognitive domains. Conclusion: The results favor the efficacy of tES in an improvement in aphasia and attentive deficits in stroke patients in acute, subacute, and chronic stages. However, the outcome of tES cannot be generalized across cognitive domains. The difference in the stimulation montages and parameters, diverse cognitive batteries, and variable number of training sessions may have contributed to the inconsistency in the outcome. We suggest that in future studies, experimental designs should be further refined, and standardized stimulation protocols should be utilized to better understand the therapeutic effect of stimulation.

Effectiveness of lever sign test for diagnosing anterior cruciate ligament rupture.

Objective: To evaluate the effectiveness of the Lever Sign test (LST) for diagnosing anterior cruciate ligament (ACL) ruptures. Methods: This prospective trial was conducted from January to December 2020. A total of 73 patients, aged 18 to 65 years, presenting with chief complaint as acute knee pain rated < 7/10 on a verbal numerical rating scale, having a minimum 20 to 120° range of motion and undergoing magnetic resonance imaging (MRI) were enrolled. Detailed history, physical examination and standard radiographic evaluation were done in all subjects. For the assessment of the integrity of the ACL, the anterior drawer, Lachman, pivot-shift and LST were performed on each symptomatic knee by a senior orthopedic consultant with a minimum five years post-fellowship experience. Sensitivity, specificity, positive predictive value (PPV), negative predictive value (NPV) and accuracy of the LST were recorded with respect to standard reference MRI findings. Results: Out of a total of 73 patients, there were 49 (67.1%) males. Mean age was noted to be 34.5±8.1 years. Area of residence was rural among 42 (57.5%) patients. Mean time since injury was noted to be 11.2±4.6 months. The MRI findings showed ACL intact among 31 (42.4%) patients while it showed ACL torn among 42 (57.5%) patients. The LST showed positive findings for ACL rupture in 39 (53.5%) patients while it was negative in remaining 34 (46.5%). The sensitivity, specificity, PPV, NPV and accuracy of LST with respect to standard reference finding (MRI) was found to be 86%, 90%, 92%, 82% and 88% respectively. Conclusion: The LST was found to have good specificity, sensitivity, PPV, NPV and accuracy to detect the status of the ACL. The LST is easy to perform can be used along with other standard assessment techniques to further increase the validation of the status of the ACL diagnosis.

In silico multi-epitope vaccine against covid19 showing effective interaction with HLA-B*15:03

The recent outbreak of severe acute respiratory syndrome (SARS) coronavirus (CoV)-2 (SARS-CoV-2) causing coronavirus disease (covid19) has posed a great threat to human health. Previous outbreaks of SARS-CoV and Middle East respiratory Syndrome CoV (MERS-CoV) from the same CoV family had posed similar threat to human health and economic growth. To date, not even a single drug specific to any of these CoVs has been developed nor any anti-viral vaccine is available for the treatment of diseases caused by CoVs. Subunits present in spike glycoproteins of SARS-CoV and SARS-CoV-2 are involved in binding to human ACE2 Receptor which is the primary method of viral invasion. As it has been observed in the previous studies that there are very minor differences in the spike glycoproteins of SARS-CoV and SARS-CoV-2. SARS-CoV-2 has an additional furin cleavage site that makes it different from SARS-CoV (Walls et al., 2020). In this study, we have analyzed spike glycoproteins of SARS-CoV-2 and SARS-CoV phylogenetically and subjected them to selection pressure analysis. Selection pressure analysis has revealed some important sites in SARS-CoV-2 and SARS-CoV spike glycoproteins that might be involved in their pathogenicity. Further, we have developed a potential multi-epitope vaccine candidate against SARS-CoV-2 by analyzing its interactions with HLA-B*15:03 subtype. This vaccine consists of multiple T-helper (TH) cells, B-cells, and Cytotoxic T-cells (CTL) epitopes joined by linkers and an adjuvant to increase its immunogenicity. Conservation of selected epitopes in SARS, MERS, and human hosts, suggests that the designed vaccine could provide cross-protection. The vaccine is designed in silico by following a reverse vaccinology method acknowledging its antigenicity, immunogenicity, toxicity, and allergenicity. The vaccine candidate that we have designed as a result of this work shows promising result indicating its potential capability of simulating an immune response.

Using fentanyl and propofol for tracheal intubation during sevoflurane induction without muscle relaxants in children: A randomized prospective study.

CONTEXT: Tracheal intubation is frequently facilitated with sevoflurane induction without the use of muscle relaxants in children. AIM: The aim of this study was to compare the effects of two different doses of propofol preceded by a fixed dose of fentanyl during sevoflurane induction on quality of tracheal intubation in children. SETTINGS AND DESIGN: This was a prospective randomized study. SUBJECTS AND METHODS: Ninety American Society of Anesthesiologists I-II children aged 2-6 years were randomly assigned to one of two equal groups to receive 2 µg/kg of fentanyl with 2 mg/kg of propofol (Group I) or 2 µg/kg of fentanyl with 3 mg/kg of propofol (Group II) during sevoflurane induction. The intubating conditions and hemodynamic responses were evaluated. The time from sevoflurane induction to loss of consciousness, to intravenous line insertion, and to intubation was measured. The occurrence of any adverse effect was recorded. STATISTICAL ANALYSIS USED: Results were analyzed using Student's t-test, paired t-test, and Chi-square test. P < 0.05 was considered statistically significant. RESULTS: The incidence of excellent intubating conditions was achieved more significantly in Group II (41/45 patients, 91%) than that in Group I (31/45 patients, 69%) (P = 0.008) (95% confidence interval [CI] =0.39-0.8). Whereas, there were no significant differences between the two groups in terms of the overall acceptable intubating conditions in Group I (40/45 patients, 89%) and Group II (43/45 patients, 96%) (P = 0.81) (95% CI = 0.71-1.31). No patient developed any adverse effect. CONCLUSION: The administration of 3 mg/kg propofol preceded by 2 µg/kg fentanyl provided a higher proportion of excellent intubating conditions compared with 2 mg/kg propofol preceded by 2 µg/kg fentanyl during sevoflurane induction in children without muscle relaxants.
