Revolutionizing Feature Selection: A Breakthrough Approach for Enhanced Accuracy and Reduced Dimensions, with Implications for Early Medical Diagnostics

Background: The system\u27s performance may be impacted by the high-dimensional feature dataset, attributed to redundant, non-informative, or irrelevant features, commonly referred to as noise. To mitigate inefficiency and suboptimal performance, our goal is to identify the optimal and minimal set of features capable of representing the entire dataset. Consequently, the Feature Selector (Fs) serves as an operator, transforming an m-dimensional feature set into an n-dimensional feature set. This process aims to generate a filtered dataset with reduced dimensions, enhancing the algorithm\u27s efficiency. Methods: This paper introduces an innovative feature selection approach utilizing a genetic algorithm with an ensemble crossover operation to generate the most robust offsprings, i.e., feature set solutions. The selection process is driven by computed minimum objective function values (OFVs). Experimental evaluations were conducted across diverse datasets sourced from various repositories, all processed through a standardized classifier. A comparative analysis was performed, contrasting the proposed feature selection system with various traditional counterparts. Results: Our innovative approach yielded superior results compared to conventional feature selection techniques in terms of accuracy and the reduction in the number of features. This holds significant promise as a valuable tool for the diagnosis of lung cancer and pancreatic cancer. Conclusion: In addition to surpassing traditional feature selection techniques in accuracy and feature reduction, our novel approach holds great potential across diverse fields, with a particularly promising impact in the medical domain for early diagnostics. This advancement could contribute significantly to the timely and effective identification of medical conditions, enhancing the overall capabilities of diagnostic processes

In vivo evaluation of ziram induced acute toxicity on pathomorphology of broiler chicken

Fungicides are usually used in agriculture and often find their way in poultry feed. Therefore, a study was undertaken to study the in vivo effect of one such fungicide (ziram) induced intoxication on pathomorphology of broiler chicken. After 2 weeks of age the birds were given fungicide (Ziram) in feed as a single oral dose of 100 mg/kg body weight. Out of 10 birds, 3 died due to ziram intoxication (30% mortality rate). Birds that died rapidly showed pronounced neurological signs like convulsions. The carcasses of ziram intoxicated birds appeared dehydrated and their mucous membrane was pale in colour. Marked vascular congestion was observed in brain on gross examination. The livers showed congestion and haemorrhages with necrotic foci. Kidneys and lungs had ecchymotic haemorrhages and heart revealed gelatinization of pericardium, distention and pericarditis. Atrophy of bursa of Fabricius and thymus; hypertrophy of thyroid was found. Histopathological examination revealed neuronal degeneration and necrosis associated with mild gliosis in brain. Lungs, pericardium and epicardium had severe congestion and there was degeneration with separation of myofibers. Glomeruli were congested and frequently revealed hypercellularity. There were sinusoidal congestion and varying degrees of hepatocellular degeneration. Bursa revealed mild depletion of lymphoid cells in few lobules while as thymus showed hypoplasia with depletion of lymphocytes. Thyroid had mild mononuclear cell infiltration and caecum showed marked necrosis and denudation of the mucosa. In conclusion, the depletion of lymphoid tissue from lymphoid organs was suggestive of immunosuppressive and immunomodulatory effects of ziram toxicity in broiler chicken

Prevalence and clinical correlates of psychiatric morbidity among caregivers of patients attending a psychiatric hospital in North India

Background: Consequent to the high prevalence of psychiatric disorders in present day world, their caregivers form an important group in the public health. Research on the physical and psychological well-being of caregivers is being carried worldwide with varied results. Psychological health of these caregivers is usually ignored both by these persons themselves and the health-care providers. The objective of the study was to screen for psychiatric morbidity among caregivers of patients attending a psychiatric hospital in North India, and to study the clinical correlates of the same.Methods: A total of 205 patients and their caregivers were consecutively recruited over a one month period. Sociodemographic and clinical information of patients was obtained either from the hospital records or from the caregiver. Scoring of the patient’s global assessment of functioning (GAF) was done by clinicians. The caregivers were administered a sociodemographic questionnaire, general health questionnaire (GHQ-12) and Zarit Burden interview. The presence of psychiatric morbidity was confirmed by a consultant psychiatrist.Results: Among the caregivers, 32.2% had GHQ scores of 3 and above. Majority of caregivers in this study were females (59.0%) while as majority of the patients were males (61.9%). Factors associated with psychiatric morbidity among caregivers include the high level of subjective burden of care, low level of functioning, and comorbid medical and psychiatric conditions.Conclusions: The study reveals a high level of psychiatric morbidity among the caregivers of patients with mental health problems

Inter-markets volatility spillover in U.S. bitcoin and financial markets

This paper investigates the volatility spillover dynamics between U.S. Bitcoin and financial markets from July 19, 2010 to December 29, 2017. Diebold and Yilmaz (2012) volatility spillover index, Barunik, Kocenda, and Vacha (2017) Spillover Asymmetry Measure, and Barunik and Krehlik (2018) frequency connectedness methodologies are applied to investigate the time varying dynamics of volatility spillover among U.S. Bitcoin and financial markets. The findings of the study indicate the presence of low level of integration and contagion between U.S. Bitcoin and financial markets. Asymmetric nature of volatility spillover is also detected. The connectedness among the U.S. Bitcoin and financial markets is found to be concentrated at high frequency, suggesting that markets process information rapidly. Moreover, the turbulence in Bitcoin market will have insignificant effect on U.S. financial markets. This non-contagion nature of Bitcoin markets provides significant risk hedging and diversification benefits for domestic and foreign investors in the U.S

KCNT1- related epilepsy: An international multicenter cohort of 27 pediatric cases

ObjectiveThrough international collaboration, we evaluated the phenotypic aspects of a multiethnic cohort of KCNT1- related epilepsy and explored genotype- phenotype correlations associated with frequently encountered variants.MethodsA cross- sectional analysis of children harboring pathogenic or likely pathogenic KCNT1 variants was completed. Children with one of the two more common recurrent KCNT1 variants were compared with the rest of the cohort for the presence of particular characteristics.ResultsTwenty- seven children (15 males, mean age = 40.8 months) were included. Seizure onset ranged from 1 day to 6 months, and half (48.1%) exhibited developmental plateauing upon onset. Two- thirds had epilepsy of infancy with migrating focal seizures (EIMFS), and focal tonic seizures were common (48.1%). The most frequent recurrent KCNT1 variants were c.2800G>A; p.Ala934Thr (n = 5) and c.862G>A; p.Gly288Ser (n = 4). De novo variants were found in 96% of tested parents (23/24). Sixty percent had abnormal magnetic resonance imaging (MRI) findings. Delayed myelination, thin corpus callosum, and brain atrophy were the most common. One child had gray- white matter interface indistinctness, suggesting a malformation of cortical development. Several antiepileptic drugs (mean = 7.4/patient) were tried, with no consistent response to any one agent. Eleven tried quinidine; 45% had marked (>50% seizure reduction) or some improvement (25%- 50% seizure reduction). Seven used cannabidiol; 71% experienced marked or some improvement. Fourteen tried diet therapies; 57% had marked or some improvement. When comparing the recurrent variants to the rest of the cohort with respect to developmental trajectory, presence of EIMFS, >500 seizures/mo, abnormal MRI, and treatment response, there were no statistically significant differences. Four patients died (15%), none of sudden unexpected death in epilepsy.SignificanceOur cohort reinforces common aspects of this highly pleiotropic entity. EIMFS manifesting with refractory tonic seizures was the most common. Cannabidiol, diet therapy, and quinidine seem to offer the best chances of seizure reduction, although evidence- based practice is still unavailable.Peer Reviewedhttps://deepblue.lib.umich.edu/bitstream/2027.42/154940/1/epi16480_am.pdfhttps://deepblue.lib.umich.edu/bitstream/2027.42/154940/2/epi16480.pd

Effect of quercetin on steroidogenesis and folliculogenesis in ovary of mice with experimentally-induced polycystic ovarian syndrome

IntroductionPolycystic Ovary syndrome (PCOS) affects the health of many women around the world. Apart from fundamental metabolic problems connected to PCOS, focus of our study is on the role of quercetin on genes relevant to steroidogenesis and folliculogenesis.MethodsEighteen mature parkes strain mice (4-5 weeks old) weighing 18–21 g were randomly divided into three groups of six each as follows: Group I serves as the control and was given water and a regular chow diet ad lib for 66 days; group II was given oral gavage administration of letrozole (LETZ) (6 mg/kg bw) for 21 days to induce PCOS and was left untreated for 45 days; For three weeks, Group III received oral gavage dose of LETZ (6 mg/kg), after which it received Quercetin (QUER) (125 mg/kg bw orally daily) for 45 days.ResultsIn our study we observed that mice with PCOS had irregular estrous cycle with increased LH/FSH ratio, decreased estrogen level and decline in expression of Kitl, Bmp1, Cyp11a1, Cyp19a1, Ar, lhr, Fshr and Esr1 in ovary. Moreover, we observed increase in the expression of CYP17a1, as well as increase in cholesterol, triglycerides, testosterone, vascular endothelial growth factor VEGF and insulin levels. All these changes were reversed after the administration of quercetin in PCOS mice.DiscussionQuercetin treatment reversed the molecular, functional and morphological abnormalities brought on due to letrozole in pathological and physiological setting, particularly the issues of reproduction connected to PCOS. Quercetin doesn’t act locally only but it acts systematically as it works on Pituitary (LH/FSH)- Ovary (gonad hormones) axis. the Side effects of Quercetin have to be targeted in future researches. Quercetin may act as a promising candidate for medical management of human PCOS

Effects of a high-dose 24-h infusion of tranexamic acid on death and thromboembolic events in patients with acute gastrointestinal bleeding (HALT-IT): an international randomised, double-blind, placebo-controlled trial

Background: Tranexamic acid reduces surgical bleeding and reduces death due to bleeding in patients with trauma. Meta-analyses of small trials show that tranexamic acid might decrease deaths from gastrointestinal bleeding. We aimed to assess the effects of tranexamic acid in patients with gastrointestinal bleeding. Methods: We did an international, multicentre, randomised, placebo-controlled trial in 164 hospitals in 15 countries. Patients were enrolled if the responsible clinician was uncertain whether to use tranexamic acid, were aged above the minimum age considered an adult in their country (either aged 16 years and older or aged 18 years and older), and had significant (defined as at risk of bleeding to death) upper or lower gastrointestinal bleeding. Patients were randomly assigned by selection of a numbered treatment pack from a box containing eight packs that were identical apart from the pack number. Patients received either a loading dose of 1 g tranexamic acid, which was added to 100 mL infusion bag of 0·9% sodium chloride and infused by slow intravenous injection over 10 min, followed by a maintenance dose of 3 g tranexamic acid added to 1 L of any isotonic intravenous solution and infused at 125 mg/h for 24 h, or placebo (sodium chloride 0·9%). Patients, caregivers, and those assessing outcomes were masked to allocation. The primary outcome was death due to bleeding within 5 days of randomisation; analysis excluded patients who received neither dose of the allocated treatment and those for whom outcome data on death were unavailable. This trial was registered with Current Controlled Trials, ISRCTN11225767, and ClinicalTrials.gov, NCT01658124. Findings: Between July 4, 2013, and June 21, 2019, we randomly allocated 12 009 patients to receive tranexamic acid (5994, 49·9%) or matching placebo (6015, 50·1%), of whom 11 952 (99·5%) received the first dose of the allocated treatment. Death due to bleeding within 5 days of randomisation occurred in 222 (4%) of 5956 patients in the tranexamic acid group and in 226 (4%) of 5981 patients in the placebo group (risk ratio [RR] 0·99, 95% CI 0·82–1·18). Arterial thromboembolic events (myocardial infarction or stroke) were similar in the tranexamic acid group and placebo group (42 [0·7%] of 5952 vs 46 [0·8%] of 5977; 0·92; 0·60 to 1·39). Venous thromboembolic events (deep vein thrombosis or pulmonary embolism) were higher in tranexamic acid group than in the placebo group (48 [0·8%] of 5952 vs 26 [0·4%] of 5977; RR 1·85; 95% CI 1·15 to 2·98). Interpretation: We found that tranexamic acid did not reduce death from gastrointestinal bleeding. On the basis of our results, tranexamic acid should not be used for the treatment of gastrointestinal bleeding outside the context of a randomised trial

Reducing the environmental impact of surgery on a global scale: systematic review and co-prioritization with healthcare workers in 132 countries

Abstract Background Healthcare cannot achieve net-zero carbon without addressing operating theatres. The aim of this study was to prioritize feasible interventions to reduce the environmental impact of operating theatres. Methods This study adopted a four-phase Delphi consensus co-prioritization methodology. In phase 1, a systematic review of published interventions and global consultation of perioperative healthcare professionals were used to longlist interventions. In phase 2, iterative thematic analysis consolidated comparable interventions into a shortlist. In phase 3, the shortlist was co-prioritized based on patient and clinician views on acceptability, feasibility, and safety. In phase 4, ranked lists of interventions were presented by their relevance to high-income countries and low–middle-income countries. Results In phase 1, 43 interventions were identified, which had low uptake in practice according to 3042 professionals globally. In phase 2, a shortlist of 15 intervention domains was generated. In phase 3, interventions were deemed acceptable for more than 90 per cent of patients except for reducing general anaesthesia (84 per cent) and re-sterilization of ‘single-use’ consumables (86 per cent). In phase 4, the top three shortlisted interventions for high-income countries were: introducing recycling; reducing use of anaesthetic gases; and appropriate clinical waste processing. In phase 4, the top three shortlisted interventions for low–middle-income countries were: introducing reusable surgical devices; reducing use of consumables; and reducing the use of general anaesthesia. Conclusion This is a step toward environmentally sustainable operating environments with actionable interventions applicable to both high– and low–middle–income countries

Narcissism, Self-esteem, and Dimensions of Aggression in Adolescents

The Subject of this study is narcissism, self-esteem, and aggression in adolescents. The aim of the current study was to investigate the relationship between narcissism, self-esteem and dimensions of aggression and compare sex differences in these variables in adolescents. 258 adolescents (124 boys and 134 girls) 14-18 years old, were selected by using multistage cluster random sampling method and were assessed by Narcissistic personality inventory (NPI-16) self- esteem and Aggression questionnaires. Data were analyzed using Pearson's correlation coefficient, multiple regression analysis and T test. The results showed positive significant relations between narcissism, self-esteem and aggression and negative relations between self-esteem and aggression. Multiple regression analysis showed that low self-esteem is most responsible in predicting aggression in adolescents. The findings showed no sex differences in features of narcissism and self esteem among adolescents and sex differences in the dimensions of aggression was observed only in physical aggression. The results of this study can be beneficial for a better understanding of theoretical and clinical relationship between narcissism, self-esteem, and aggression in adolescents

Pattern of winter depression among Kashmiri patients

Background: Seasonal affective disorder (SAD) or SAD is a type of recurring major depression having a seasonal pattern of onset and termination of mood episodes. Even though SAD can occur during the summer season, but the winter pattern is most commonly recognized. The prevalence of SAD varies with the climate and latitude of regions. In this study, we aimed to study the clinical profile of SAD among Kashmiri patients. Materials and Methods: It was a cross-sectional study among fifty patients attending an outpatient clinic of a tertiary care hospital in Kashmir, North India. Patients were diagnosed with SAD as per the diagnostic and statistical manual, 5th version, and were assessed for the clinical pattern of winter depression; months of September to May. Results: Patients were predominantly females (72%), in the age group of 20–30 years (36%), and were married (64%). Depressive mood (96%) and anxious mood (74%) were the most common mood symptoms. Decreased energy and decreased libido were present in 82% and 70% of patients. November to late April was the period when the majority of the patients had depressive symptoms (32%). In 44% of the patients, symptoms were most severe in late February. Conclusion: Females predominated the study group while the commonest age group was 20–30 years. Low/anxious mood and reduction in energy were the most common features. The onset of symptoms was in the months of September-December and remission in the months of March-May
