Designing of an Enhanced Fuzzy Logic Controller of an Interior Permanent Magnet Synchronous Generator under Variable Wind Speed.

On account of active governmental stimulation operations in many countries, the residential production of electricity from renewable resources has increased considerably. Due to high efficiency and reliability, a recommended solution for residential wind energy conservation systems (WECS) is permanent magnet synchronous generators (PMSG). A higher torque ripple (TR), engendered by the contact of the stator with the rotor's magnetomotive force harmonics, is one foremost issue in PMSGs. To control the synchronous generator, numerous control schemes have been proposed. However, it still faces a challenge in the diminishment of the TR. An enhanced fuzzy logic controller (EFLC) in interior PMSG (IPSMG) under variable wind speed (WS) has been proposed in this article to address this challenge. Initially, the wind turbine (WT) system was designed, and the IPMSG was proposed. A hysteresis controller (HC) and fuzzy logic controller (FLC) are the two controller types utilized in this model to control TR. This methodology used the EFLC to eliminate errors during the control. By using the proper membership function (MF) for boundary selection in the WDCSO algorithm, an enhancement was executed. Better performance in TR reduction was attained by the proposed model grounded in the analysis.

Analysis of clinical profile and role of various prognostic factors in early bone marrow response in children with acute lymphoblastic leukemia treated by Modified Multicenter Protocol (MCP) 841 protocol: Experience from a tertiary care center in North India.

BACKGROUND: It is important to study the clinical profile of pediatric patients with acute lymphoblastic leukemia (ALL) and assess various prognostic factors implicated in response to induction chemotherapy for optimal treatment outcomes in India. The present study was done to evaluate the clinical profile and to find the correlation of day 7 and day 28 marrow blast response with already established prognostic factors in children with ALL in the region of North India using MCP 841 protocol for all patients. METHODS: A total of 60 children up to ages 14 years with ALL were given treatment in the form of induction remission (MCP-841 protocol) I1 cycle (induction 1) therapy for 29 days. Complete hemogram for blast cells and bone marrow examination (bone marrow aspiration and, if required, bone marrow biopsy) was done on days 7 and 28 (completion of I1 cycle) to see early bone marrow response. Early response to induction therapy was compared in patients with and without high-risk factors, and results were analyzed statistically. RESULTS: Out of 60 enrolled children, 56 (93.4%) patients were in complete remission at the end of induction 1 cycle. Various risk factors were found to be of prognostic significance in first remission and early response to induction therapy were initial total leukocyte count (TLC) at presentation, immunophenotype of ALL; while other factors including age and sex was not found to be significant. CONCLUSION: Prevalence and significance of various prognostic factors implicated in pediatric ALL tend to be different in various populations. A better understanding of such factors in these populations will help in the tailoring of risk-adapted treatment protocols to local needs.

Artificial Intelligence on Diagnostic Aid of Leprosy: A Systematic Literature Review.

Leprosy is a neglected tropical disease that can cause physical injury and mental disability. Diagnosis is primarily clinical, but can be inconclusive due to the absence of initial symptoms and similarity to other dermatological diseases. Artificial intelligence (AI) techniques have been used in dermatology, assisting clinical procedures and diagnostics. In particular, AI-supported solutions have been proposed in the literature to aid in the diagnosis of leprosy, and this Systematic Literature Review (SLR) aims to characterize the state of the art. This SLR followed the preferred reporting items for systematic reviews and meta-analyses (PRISMA) framework and was conducted in the following databases: ACM Digital Library, IEEE Digital Library, ISI Web of Science, Scopus, and PubMed. Potentially relevant research articles were retrieved. The researchers applied criteria to select the studies, assess their quality, and perform the data extraction process. Moreover, 1659 studies were retrieved, of which 21 were included in the review after selection. Most of the studies used images of skin lesions, classical machine learning algorithms, and multi-class classification tasks to develop models to diagnose dermatological diseases. Most of the reviewed articles did not target leprosy as the study's primary objective but rather the classification of different skin diseases (among them, leprosy). Although AI-supported leprosy diagnosis is constantly evolving, research in this area is still in its early stage, then studies are required to make AI solutions mature enough to be transformed into clinical practice. Expanding research efforts on leprosy diagnosis, coupled with the advocacy of open science in leveraging AI for diagnostic support, can yield robust and influential outcomes.

A Retrospective Study of Ultrasound-Guided Pericapsular Nerve Group Block With Dexamethasone: An Excellent Option for Early Mobility Following Total Hip Replacement Surgery.

Background Severe postoperative pain and immobility increase the length of hospital stay and immobility-related life-threatening complications after total hip replacement (THR). Pericapsular nerve group (PENG) block is a recent addition to pain management of neck of femur (NoF) fracture, the use of which has been incorporated into THR as alternative analgesia or as an adjunct with other regional analgesia techniques. The present study primarily aims to assess postoperative mobility. Secondary outcomes measured were the length of hospital stay, pain score, opioid consumption, and side effects. Methods This is a retrospective study of 50 patients who underwent primary THR. Twenty-eight patients received PENG block after spinal anesthesia (PENG Group), seven patients had general anesthesia (GA) with patient-controlled analgesia (PCA) postoperatively (PCA Group), and the remaining 15 received spinal anesthesia with fascia iliaca block (FIB Group). Mobilization was attempted in all patients (ability to stand and walk a few steps with a walker) 10 hours after the end of surgery. Data was collected for average postoperative pain score, time of mobilization, total opioid consumption (till discharge from the hospital), opioid-related side effects, and time of discharge. Results Mobilization was attempted in all patients 10 hours after the end of the surgery, irrespective of their anesthetic technique. In the PENG Group, 26 patients (n=28) could be mobilized after the first 10 hours without opioids. The total morphine requirement until discharge was significantly less in the PENG Group of patients compared to the FIB and GA+PCA patients. The average time of discharge (hours) from the hospital (22.1+/-4.9) was also significantly lower in the PENG Group compared to all other groups (31.7 +/- 3.4, p=<0.01). The average postoperative pain score was significantly low in the PENG Group within the first 48 hours. Conclusion The PENG block helps in early mobilization and enhanced recovery after THR.

Suicide deaths among medical students, residents and physicians in India spanning a decade (2010-2019): An exploratory study using on line news portals and Google database.

BACKGROUND: Despite having one of the world's largest medical education consortium, India lacks a comprehensive and nationally representative data on suicide deaths among medical students and physicians unlike the one found in most of the developed nations of the world. AIM: We aimed to explore the different characteristics of suicide deaths among medical students, residents and physicians in India over a decade (2010-2019). METHODS: Content analysis of all suicide death reports among medical students, residents and physicians available from online news portals and other publicly available sites was done. Search was done retrospectively using pertinent search words individually or in combination with language restricted to Hindi and English and timed from January 2010 to December 2019. Reports on completed suicide by allopathic medical students, residents and physicians from India were included. Socio-demographic and suicidological variables were analysed using R software. RESULTS: A total of 358 suicide deaths among medical students (125), residents (105) and physicians (128) were reported between 2010 and 2019. Around 7 out of 10 suicides happened before the age of 30 and had mean age 29.9 (±12.2) years. Female residents and physicians were younger than their male counterparts at the time of suicide. Overall maximum suicide deaths were concentrated in South India except the state of Kerala. The specialty of anesthesiology (22.4%) followed by obstetrics-gynaecology (16.0%) had the highest suicide deaths. Violent suicide methods were more commonly used by all, with hanging being the most common mean of suicide. Academic stress among medical students (45.2%) and residents (23.1%), and marital discord among physicians (26.7%) were the most noticeable reasons for suicide. Mental health problems were the next most common reason in medical students (24%) and physicians (20%) while harassment (20.5%) was in residents. Twenty six percent had exhibited suicide warning signs and only 13% had ever sought psychiatric help before ending their lives. A total of nine reports of suicide pact were found with the average deaths per pact being 2.4 and predominantly driven by financial reasons. CONCLUSION: Academic stress among medical students and residents, and marital discord in physicians emerged as the key reasons for suicide. However, this preventable domain should be further explored through focused research. This is the first of its kind study from India which attempted to explore this vital yet neglected public health issue using the most feasible and practical method of online news content-based analysis.

Seven versus Ten Days Antibiotics Course for Acute Pyogenic Meningitis in Children: A Randomized Controlled Trial.

OBJECTIVES: To compare the efficacy and safety of 7 d vs. 10 d empirical antibiotic therapy in cases of acute pyogenic meningitis in children aged 3 mo to 14 y with rapid initial recovery. METHODS: A total of 96 children aged 3 mo to 14 y with acute pyogenic meningitis were randomized to either 7 d or 10 d therapy on Day 5 of the therapy, if they were in clinical remission and had improving cerebrospinal fluid (CSF) abnormalities. The primary outcome was treatment failure in each group within 10 d of enrolment or relapse of meningitis defined as recurrence of signs and symptoms of meningitis within 2 wk of discharge. Secondary outcome was the presence of sequelae in patient at 30 d and 90 d follow-up post discharge. RESULTS: Out of 111 screened children, 96 patients completed the trial, 48 in each group. There were 7 treatment failures and relapses each in the group receiving 7 d antibiotics while 6 failures and relapses each were seen in 10 d antibiotics group. There was no statistically significant difference in treatment failure in both the groups [2.1 (-0.12-0.16); p = 0.76]. No deaths or significant adverse effects of the drugs occurred during this study. Four cases of nosocomial sepsis were reported with 2 cases in each group. On subsequent 30 d and 90 d follow-up, no statistically significant difference was found between the two groups regarding frequency of hearing impairment, frequency of hydrocephalus [-2.1 (-0.09-0.13); p = 0.65] and various neurological sequelae [6.2 (-0.06-0.19); p > 0.05]. CONCLUSIONS: Short course antibiotic therapy may be adequately effective for treatment of acute pyogenic meningitis beyond neonatal age in children with initial rapid recovery.

Impact of a Brief Structured Psychoeducation Session on Antiepileptic Drug Adherence and Treatment Outcome in Persons with Epilepsy: A Prospective Cohort Study.

BACKGROUND: Poor adherence to antiepileptic drugs is one of the most important causes of treatment failure in persons with epilepsy (PWE). This study was aimed at assessing the impact of psychoeducation on drug adherence and treatment outcome in PWE. METHODS: It was a prospective cohort study with a pre and posttest intervention design. A cohort of 100 epilepsy patients aged 18-65 years and on antiepileptic drugs for at least 6 months attending the outpatient department was enrolled in the study. Drug adherence was measured by Medication Adherence Rating Scale. A structured eight-domain epilepsy psychoeducation session with pictorial description was given to the study subjects in two parts (group and individually) lasting for a total of 30 min on the day of baseline assessment. Adherence and treatment outcome variables were assessed by an independent observer 4 months after the psychoeducation session. Chi-square test and paired t-test were used to analyze the data using SPSS version 20 with P value less than 0.05 considered as significant. RESULTS: There was a statistically significant (P < 0.001) increase in the number of patients who were adherent to medications after psychoeducation session. There was a significant reduction in mean seizure frequency (0.68 ± 0.65) and seizure severity in terms of injuries sustained during seizure episodes post intervention. Regularities in the follow-up visits were also witnessed. A significant decrease in the number of hospital admissions (0.09 ± 0.32), mean inpatient treatment days (0.44 ± 2.19), and emergency room visits (0.19 ± 0.15) was noted 4 months after the psychoeducation session indicative of better treatment outcome. CONCLUSION: The present study proves the efficacy of a structured educational program in improving drug adherence and treatment outcome in a cohort of people with epilepsy.

Factors Associated with Poor Antiepileptic Drugs Adherence in Below Poverty Line Persons with Epilepsy: A Cross-Sectional Study.

Background Adherence to antiepileptic drugs (AED) is essential for adequate seizure control in epilepsy. People with low socioeconomic status are more vulnerable to poor adherence to AED. The present study aimed to explore factors associated with poor adherence to antiepileptic drugs in below poverty line (BPL) persons with epilepsy (PWE). Methods The research had a cross-sectional design with inclusion of persons aged 18 to 65 years and an established diagnosis of epilepsy. Holding a BPL card (Yellow card) was taken as a measure for BPL criteria. Adherence to antiepileptic drugs was assessed using medication adherence rating scale (MARS). Univariate analysis with Chi-square test was used to determine the association between various variables and AED adherence, while the predictors of adherence were identified using multivariate logistic regression analysis. Results There was a total of 88 BPL PWE. The mean age of male and female patients was 35.0 ± 15.0 & 32.0 ± 10.1 years, respectively. Adherence for drugs were found to be 30.7% and nonadherence to be 44.3%. Low (illiterate or primary) education (OR 0.041 [0.01-0.21]), polytherapy (OR 0.088 [0.02-0.40]), and substance abuse (OR 0.05 [0.01-0.58]) were found to have significant association with nonadherence to AEDs. Age, gender, marital status, family composition, occupation, rural urban background, distance from health care facility, duration of epilepsy, and side effects of AED were not found to have significant association with adherence. Conclusion There is a need for psychoeducational programs for the people having low education status and polytherapy to form positive beliefs in AEDs. Substance abuse should also be addressed while treating them.

Comparison of Ultrasonography and X-Rays for the Diagnosis of Synovitis and Bony Erosions in Small Joints of Hands in Early Rheumatoid Arthritis: a Prospective Study.

Objective: Rheumatoid arthritis (RA) is the most common inflammatory joint disease. Many studies have shown that erosions and synovitis can be picked up at an early stage on ultrasonography (US) when X-rays appear normal. Ultrasonography exams in inflammatory arthritis helps in determining objective evidence of inflammatory arthritis- synovitis, erosions, effusions and also help in monitoring therapy in established RA patients. Materials and methods: Ninety patients aged over 18 years, who were diagnosed with RA (according to 2010 ACR criteria) of less than two years duration, were included in the study prospectively. Baseline data, disease activity score of 28 joints (DAS 28 score), complete clinical evaluation and laboratory investigations were registered. Conventional radiographs of both hands were taken in posteroanterior views. A power Doppler US was performed on all metacarpophalangeal (MCP) joints and proximal interphalangeal (PIP) joints of both hands. Results: Out of the 90 patients, 84 had positive findings on US and only 13 subjects had positive radiographic findings. The second MCP was the most common joint involved on US. The mean cumulative flow signal (CFS) score was 4.15±5.12. The relation between CFS and DAS 28 scores was highly significant, with p value <0.01. Conclusion: Ultrasonography can detect changes in joints at an earlier stage than radiographs. Both grey scale and power Doppler US have a role in detecting synovitis and erosions.

A comparative study of serum zinc levels in small for gestational age babies and appropriate for gestational age babies in a Tertiary Hospital, Punjab.

INTRODUCTION: Zinc deficiency is very much prevalent among pregnant women in developing countries. Zinc is required to maintain normal structure and function of multiple enzymes including those that are involved in foetal growth. Zinc deficiency increases risk of baby being born preterm, low birth weight, small for gestational age (SGA). AIMS AND OBJECTIVES: To compare serum zinc levels in small for gestational age babies with respect to appropriate for gestational age (AGA). MATERIAL AND METHODS: Out of total 200 newborn, hundred SGA newborn comprised the study group and hundred AGA newborn comprised the control group. Cord blood sample was collected immediately after birth and zinc levels were determined by atomic absorption spectrophotometry method. RESULTS: The mean (±SD) serum zinc levels of study and control groups were 56.8 ± 40.6 µg/dl and 107.4 ± 72 µg/dl respectively and difference between two groups were found to be statistically significant. The mean serum zinc levels of preterm SGA group and term SGA group were 46.26 ± 22.54 µg/dl and 63.35 ± 47.47µg/dl respectively. Statistically significant difference was found in mean serum zinc levels between the two groups. CONCLUSION: SGA neonates have significant zinc deficiency as compared to AGA neonates. This zinc deficiency is even more pronounced in SGA newborns that are born preterm. This warrants the future investigation and necessary intervention on zinc supplementation during pregnancy and to preterm and SGA babies for better maternal and child health outcomes.

Prevalence and risk factors for nonalcoholic fatty liver disease in obese children in rural Punjab, India.

BACKGROUND: Pediatric nonalcoholic fatty liver disease (NAFLD) is associated with insulin resistance, hypertension, metabolic syndrome, cardiovascular problems, and increased risk of chronic liver disease and Type II diabetes mellitus. The aim of the study was to assess the metabolic profiles and associated risk factors of NAFLD in obese children. MATERIALS AND METHODS: Children with a body mass index (BMI) of >27 kg/m2 an adult equivalent cutoff (Indian Academy of Paediatrics, 2015 guidelines) aged 5-18 years presenting to the pediatric outpatient unit of PGIMER Satellite Centre, Sangrur, India, were retrospectively recruited over a 1-year period. Anthropometry, lipid profile, thyroid levels, liver function test, fasting blood sugar, and blood pressure were measured. Ultrasonography was used to diagnose NAFLD. Logistic regression was used to assess the risk factors. RESULTS: A total of 100 children participated in the study. The mean age was 10.6 ± 2.6 years and the mean BMI-Z score was 2.6 ± 0.5. The prevalence of NAFLD was 62%. Alanine transaminase (ALT) was significantly elevated in all the children with NAFLD. Lipid levels and BMI Z-score were similar in both groups. Unadjusted odds ratio shows statistically significant association of ALT (2.058 [1.11-1.01]) and waist circumference (1.089 [1.19-0.99]) with NAFLD. With adjusted odds ratio only, ALT (1.12 [1.24-1.01]) was found to be significantly associated with NAFLD. CONCLUSION: There is quite a high prevalence of nonalcoholic fatty liver in obese Indian children. All children with raised liver enzymes should undergo sonography to rule out NAFLD.
