Ophthalmic adverse effects of miltefosine in the treatment of leishmaniasis: a systematic review.

OBJECTIVE: Miltefosine stands as the sole oral medication approved for the treatment of leishmaniasis. The appearance of severe ophthalmic toxicities induced by miltefosine in the context of leishmaniasis treatment is a matter of significant concern. The main objective of this study is to present a comprehensive summary of the ophthalmic adverse effects associated with miltefosine when used in the treatment of leishmaniasis. METHODS: A systematic search was performed on PubMed, ScienceDirect, Embase, Scopus, and Google Scholar, covering articles from inception up to June 2023, without language restrictions, to identify relevant studies documenting ocular toxicity following miltefosine treatment for leishmaniasis. RESULTS: A total of eight studies involving 31 leishmaniasis patients who developed ocular toxicities while undergoing miltefosine treatment were included in the analysis. These studies were conducted in various regions, with five originating from India, two from Bangladesh, and one from Nepal. Patients presented a spectrum of ophthalmic complications, including uveitis, keratitis, scleritis, and Mooren's ulcer. Commonly reported symptoms included pain, redness, excessive tearing, partial vision impairment, permanent blindness, light sensitivity, and the appearance of white spots on the eye. On average, patients received miltefosine treatment for a duration of 47 days before experiencing the onset of ocular problems. It is important to note that the risk of ocular toxicities increases with prolonged use of miltefosine. CONCLUSIONS: Therefore, to mitigate the potential for irreversible damage to the eyes, it is imperative that all individuals undergoing miltefosine therapy undergo regular eye examinations.

A Study on Drug Prescribing Patterns in Vitiligo Patients of Andhra Pradesh in a Tertiary Care Teaching Hospital.

BACKGROUND: Vitiligo is a dermatological condition characterized by the appearance of white spots or patches on the skin due to the loss of skin pigment called melanocytes. The estimated prevalence of vitiligo is about 0.5-2% of the world population, but in India, the prevalence rate varies from 2 to 8%, depending on the region. This study aimed to assess drug prescribing patterns in vitiligo patients. MATERIALS AND METHODS: A prospective cross-sectional study was carried out in the Dermatology Department of Government General Hospital, Andhra Pradesh, India, from December 2019 to 2020. Patients aged ≥18 years, both genders, and diagnosed and receiving treatment for vitiligo were included in the study. All medicines prescribed to the patients were collected on the predesigned case report form. Ethical approval for this study was taken from the Institutional Ethics Committee of Rajiv Gandhi Institute of Medical Science (RIMS). The collected data were analyzed by using SPSS version 18. RESULTS: The most commonly prescribed class of drugs was corticosteroids (42.9%), followed by calcineurin inhibitors (13.4%), vitamins (14.6%), basic fibroblast growth factor (BFGF) (9.5%), moisturizers (6.9%), antihistamines (6.5%), and minerals (6.2%). Among corticosteroids, betamethasone was the most commonly prescribed drug, followed by clobetasol propionate. Topical drugs were prescribed more often than orally. CONCLUSION: The prescription pattern in vitiligo patients is as per the guidelines and recommendations. However, further studies using multiple centers are recommended to verify our findings.

Diagnostic, prognostic, and predictive importance of neutrophil/lymphocyte ratio (NLR), platelet/lymphocyte ratio (PLR), and CA125 in endometrial hyperplasia and carcinoma.

BACKGROUND: Inflammation has an important role in the progression of endometrial carcinoma. AIMS: The aim of this study is to find the association between neutrophil/lymphocyte ratio (NLR), platelet/lymphocyte ratio (PLR), and CA125 in endometrial hyperplasia and endometrial carcinoma. The study also focuses on the association of CA125, NLR, and PLR with histopathological parameters in endometrial carcinoma that are of prognostic importance. MATERIALS AND METHODS: This is a prospective cross-sectional study on 57 biopsy-proven cases of endometrial hyperplasia and carcinoma conducted over a period of two years. The NLR, PLR, and CA125 were calculated and recorded in all the 57 cases. RESULTS: The 57 cases were divided into three groups: endometrial hyperplasia without atypia group which included 36 cases, endometrial atypical hyperplasia group which included 10 cases, and the endometrial carcinoma group which included 11 cases. Comparison was done between the groups, and parity, NLR, PLR, and CA125 were found to be significant, but patient age and postmenopausal status were not significant. NLR, PLR, and CA125 were found to increase with higher grade, pT-stage, and nodal stage for the endometrial carcinoma cases. CONCLUSION: NLR, PLR, and CA125 were marginally increased or normal in the case of endometrial hyperplasia without atypia and endometrial atypical hyperplasia, while they were significantly increased in endometrial carcinoma, and also correlated with an increase in grade, pT-stage, and nodal stage. Hence, these can be considered for additional screening as diagnostic, prognostic, and predictive markers in case of abnormal uterine bleeding with endometrial pathology.

Poor Glycemic Control Affecting Screening of Prostate Carcinoma.

Introduction Diabetes and cancer are commonly linked together. The possible links include insulin resistance, hyperinsulinemia, hyperglycemia, oxidative stress, and chronic inflammation. These are factors that have potential promoting effects on the progression of cancer in many ways. Measurement of prostate-specific antigen (PSA) is widely applied for early detection of prostate cancer. However, several factors influence serum PSA levels in men including age, benign prostatic hyperplasia, prostatitis, and body mass index (BMI). The risk of several malignancies is increased in diabetes but the risk of prostate carcinoma in diabetic patients is reduced secondary to lowering of testosterone levels during the state of hyperinsulinemia. A negative association between serum PSA levels and metformin use is also an explanation of low cancer prostate incidence with diabetes. Objective The study aims to evaluate the PSA levels in diabetic patients with poor glycemic control i.e., glycated hemoglobin (HbA1c) ≥ 7%) vs good glycemic control (HbA1c < 7%). Materials and methods Samples of PSA in diabetic patients collected in the Department of Biochemistry at Indira Gandhi Institute of Medical Sciences (IGIMS), Patna, were included. The observational study was carried out on clinically diagnosed 318 cases of diabetes attending both the outpatient and inpatient Department, IGIMS, Patna. Six ml venous blood samples were collected from patients after obtaining informed consent and ethical clearance. Patient details regarding age, complete clinical details, and general physical examinations were recorded. Serum levels of PSA, fasting plasma glucose (FPG) and HbA1c were analyzed and values were compared. The serum level of PSA was estimated by the chemiluminescent immunoassay (CLIA) method on an automated immunoassay analyzer in the Department of Biochemistry, maintaining all the quality control precautions using a control, calibrator, and reagent kit. HbA1c estimation was by chromatography technique. Fasting plasma glucose was estimated using the hexokinase method on an automated chemistry analyzer. Statistical analyses were performed using SPSS software, version 16.0 (SPSS Inc., Chicago). The median and interquartile range were calculated for numerical variables. Covariance analysis was used in the comparisons among groups. The Mann-Whitney U test was applied to detect the comparison between the two groups. Significance was determined by the P value. P value<0.05 was considered significant. Result Serum PSA value was found to be higher in (the good glycemic control group) with a median of 0.99 with an interquartile range of 3.14, than in (the bad glycemic control group) with a median of 0.49 with an interquartile range of 3.9, and the difference is statistically significant. The difference is also statistically significant in the subgroup (i) with PSA value <4 ng/ml. In subgroups (ii) and (iii), PSA values 4 ng/ml-8 ng/ml and PSA values >8 ng/ml respectively, no significant differences were found. Conclusion It was found that serum prostate-specific antigen levels have been lower in diabetic patients with poor glycemic control than in good glycemic control. Future studies with a larger sample size and detailed information on diabetes duration and management are recommended.

Delayed sowing and its ramifications: biophysical, yield and quality analysis of wheat cultivars in the northwest Indo-Gangetic plains.

BACKGROUND: The continuous cultivation of rice-wheat in the same field is a key element of double-cropping systems in the Indo-Gangetic plains. Yields of such cropping systems are increasingly challenged as climate change drives increases in temperature, terminal stress and uneven rainfall, delaying rice harvesting and subsequently delaying sowing of wheat. In this paper, we evaluate the optimum sowing dates to achieve high grain yield and quality of wheat cultivars in northwest India. Three cultivars of wheat, HD-2967, HD-3086 and PBW-723, were sown on three different dates at the research farm of ICAR-IARI, New Delhi, to generate different weather conditions at different phenological stages. Different biophysical attributes, photosynthetic rate, stomatal conductance and transpiration rate, were measured at different phenological stages. Yield and grain quality parameters such as protein, starch, amylopectin, amylose and gluten were measured in different cultivars sown on different dates. RESULTS: Biophysical parameters were found to be higher in timely sown crops followed by late-sown and very late-sown crops. Further, the different sowing dates had a significant (P < 0.05) impact on the grain quality parameters such as protein, starch, amylopectin, amylose and gluten content. Percentage increases in the value of starch and amylose content under timely sown were ~7% and 11.6%, ~5% and 8.4%, compared to the very late-sown treatment. In contrast, protein and amylopectin contents were found to increase by ~9.7% and 7.5%, ~13.8% and 16.6% under very late-sown treatment. CONCLUSION: High-temperature stress during the grain-filling periods significantly decreased the grain yield. Reduction in the grain yield was associated with a reduction in starch and amylose content in the grains. The protein content in the grains is less affected by terminal heat stress. Cultivar HD-3086 had higher growth, yield as well as quality parameters, compared to HD-2967 and PBW-723 in all treatments, hence could be adopted by farmers in northwest India. © 2024 Society of Chemical Industry.

Effect of Neck Rotation With Flexion on Ultrasonographic Optic Nerve Sheath Diameter in Patients Undergoing Elective Craniotomy.

Background Extreme neck positioning to facilitate craniotomy can result in impaired venous drainage from the brain and a subsequent rise in increased intracranial pressure (ICP). The effects of varied neck positioning intraoperatively on ultrasonographic optic nerve sheath diameter (USG-ONSD) are still unexplored. This study aims to quantify the angle of neck rotation and flexion that can cause a significant increase in USG-ONSD in patients undergoing elective craniotomy. Methods A total of 100 patients were recruited in this non-randomized study and equally divided into two groups. In one group, patients with neck rotation ≤30 degrees and in another group, patients with neck rotation >30 degrees with varying degrees of neck flexion were included. The average of three USG-ONSD measurements in both eyes was obtained and compared in both groups at baseline, after positioning, and at the end of the surgery after making the neck neutral. Results The results of 100 recruited patients were analyzed. All the patients had neck flexion in the range of 40° to 45°, whereas the neck rotation ranged from 10° to 45°. The USG-ONSD of both eyes changed significantly from baseline to post-positioning time point in patients with neck rotation >30° (right eye p=0.038, left eye p=0.04) when compared to neck rotation ≤30°. There was no significant change in USG-ONSD from baseline to the postoperative time point after making the neck neutral (right eye p=0.245, left eye p=0.850) in both groups. Conclusions This study demonstrates that USG-ONSD, a surrogate measure of ICP, increased significantly after neck flexion with rotation >30° in neurosurgical patients. However, USG-ONSD becomes comparable to baseline after putting the patient's neck in a neutral position after surgery.

Prevalence of self-medication practices among pregnant women in India: A systematic review and meta-analysis.

BACKGROUND: Self-medication practice among pregnant women is a global concern. However, its understanding in the Indian context is limited due to a lack of comprehensive studies. PURPOSE: This study aimed to comprehensively assess the prevalence of self-medication, the medications used for self-medication, diseases/conditions associated with self-medication, and the reasons for self-medication among Indian pregnant women. METHODS: This study was carried out following the guidelines outlined in the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA). A thorough search was done in PubMed, Embase, and Google Scholar to find articles that were published up until May 2023. Inclusion criteria comprised observational studies reporting self-medication prevalence among pregnant women in India. Data were extracted using a standardized sheet, and a random-effects model was applied to determine the overall prevalence of self-medication using R software. The I2 statistic was employed to assess the heterogeneity among the studies. RESULTS: This study analyzed eight studies with a collective sample size of 2208 pregnant women. The pooled prevalence of self-medication among pregnant Indian women was 19.3% (95% CI: 7.5%-41.3%; I2 = 99%; p < 0.01). Common self-treated conditions were cold, cough, fever, headache, and stomach disorders. Antipyretics, analgesics, antihistamines, and antacids were frequently used for self-medication. The perception of mild ailment, immediate alleviation, convenience, time savings, and advice from family, friends, or the media were all reasons for self-medication. Local pharmacies were the most usual source for obtaining drugs, and pharmacists, family, friends, and past prescriptions were common sources of medicine information. CONCLUSIONS: A low yet substantial number of pregnant women in India are engaged in self-medication practices. Appropriate strategies need to be planned to reduce self-medication practices to attain sustainable developmental goals for maternal health in India.

Nonadherence to antiepileptic medication and associated factors among persons with epilepsy in India: A systematic review and meta-analysis.

BACKGROUND: Nonadherence to antiepileptic drugs (AEDs) is a prevalent issue in India, contributing to suboptimal seizure control, higher morbidity and mortality, increased hospitalization rates, and a substantial effect on the overall quality of life for individuals with epilepsy. OBJECTIVES: This study aimed to measure the prevalence of medication adherence among individuals with epilepsy in India and to identify factors associated with nonadherence. METHODS: Following PRISMA guidelines, we searched PubMed, Scopus, Embase, and Google Scholar for studies on AED adherence in India. Quality assessment employed Newcastle Ottawa Scale adapted for cross-sectional studies. Pooled prevalence was ascertained using a random-effects model in R software (version 4.2.2), with a 95% confidence interval. Heterogeneity was estimated with the I2 statistic, and publication bias was appraised via a funnel plot. Subgroup analyses, based on study region and adherence measurement tool, were done to investigate heterogeneity. RESULTS: Nine cross-sectional studies with 1772 participants were analyzed. The pooled prevalence of adherence to AEDs in India stood at 49.9% (95% CI: 39.8%-60.1%). Subgroup analyses showed comparable adherence rates in the South (50.9%) and North (46.5%) regions of India. However, adherence rates varied substantially based on the measurement tool: Morisky Medication Adherence Scale-4 (MMAS-4) reported 71.3%, MMAS-8 indicated 45.9%, and Morisky Green Levine (MGL) adherence scale exhibited 42.0%. Factors contributing to non-adherence to antiepileptic therapies involved poor socioeconomic status, lower education levels, polytherapy, drug-related side effects, and substance abuse. CONCLUSIONS: Almost half of persons with epilepsy in India were non-adherent to their AEDs. This underscores the importance for healthcare professionals to pay greater attention to improving the adherence rate to AEDs within the healthcare service.

Traumatic implantation keratitis caused by Schizophyllum commune in Central India.

We present two cases with a history of trauma to the cornea and after a few days patients developed symptoms of corneal ulcers with one showing hypopyon as well. Due to strong suspicion of fungal keratitis both cases were treated with topical and intravenously voriconazole. Fungal culture showed white fluffy growth which was identified as Schizophyllum commune by conventional and molecular methods. In both cases surgical intervention was essential. Therapeutic keratoplasty was done in both cases but failed. Unfortunately, both patients lost vision in the affected eyes.

Comparison of Opioid-Based Versus Opioid-Sparing Anesthesia in Patients Undergoing Glioma Surgery.

Background In the neurosurgical population, opioids may cause respiratory depression, leading to hypercapnia, increased cerebral blood flow (CBF), and ultimately increased intracranial pressure (ICP), which can mask early signs of intracranial complications and delayed emergence. This study was designed to compare perioperative hemodynamic stability, analgesia, and recovery parameters in opioid-based (fentanyl) general anesthesia versus opioid-sparing (dexmedetomidine) general anesthesia in patients undergoing glioma surgeries. Methodology This prospective observational comparative study compared 52 patients in two groups. Twenty-six (50%) patients in group F received Inj. fentanyl IV (intravenous; bolus 2 mcg/kg 10 minutes before induction and then infusion 1 mcg/kg/hour till 30 minutes before skin closure), whereas 26 (50%) patients in group D received Inj. dexmedetomidine IV (0.5 mcg/kg infusion 10 minutes before induction and then maintenance with a 0.5 mcg/kg/hour infusion till 30 minutes before skin closure). Perioperative heart rate (HR), mean arterial pressure (MAP), Numerical Rating Scale for Pain (NRS) assessment and postoperative emergence time, modified Aldrete score, patient satisfaction, and surgeon satisfaction score were estimated and compared in both groups. Results The mean HR was less in group D compared to group F at following time points - 10 minutes after infusion (P = 0.006), laryngoscopy and intubation (P = 0.003), pinning of the skull (P < 0.001), one hour after dura opening (P = 0.007), two hours after dura opening (P = 0.006), five minutes after extubation (P < 0.001), and 30 minutes after extubation (P = 0.011). MAP was lower in group D compared to group F at the following time intervals: 10 minutes after infusion (P = 0.008), five minutes after extubation (P = 0.007), 30 minutes after extubation (P < 0.001), and one hour after extubation (P = 0.023). A significant decrease in emergence time in group D compared to group F (P < 0.001) was noted. NRS was lower in group D at eight hours (P = 0.005) and 12 hours (P < 0.001) post-extubation. Conclusions Dexmedetomidine can be used as an alternative to fentanyl in terms of perioperative hemodynamic stability, perioperative analgesia, smooth early recovery from anesthesia, patient satisfaction, and surgeon satisfaction.

Serum Zinc Level and Efficacy of Zinc Therapy in Cutaneous Leishmaniasis: a Systematic Review and Meta-analysis.

Cutaneous leishmaniasis is a parasitic skin disease prevalent in many parts of the world. Zinc has been investigated for its potential role in the immune response against Leishmania parasites. This study aimed to systematically review the literature and conduct meta-analyses to evaluate the serum zinc level and efficacy of zinc therapy in cutaneous leishmaniasis. A comprehensive search of electronic databases was performed to find studies reporting serum zinc levels and the efficacy of zinc therapy in cutaneous leishmaniasis. Meta-analyses were conducted using RevMan software (version 5.4), calculating the mean difference for serum zinc levels and risk ratio for the efficacy of zinc therapy. A total of 11 studies with 1009 participants were evaluated. Five of these studies, comprising 637 participants, examined serum zinc levels; the remaining six, involving 372 individuals, examined the effectiveness of zinc therapy in treating cutaneous leishmaniasis. The results showed that the serum zinc level was significantly lower in cutaneous leishmaniasis patients compared to controls (MD: - 26.65; 95% CI: [- 42.74, - 10.57]; p = 0.001). However, zinc therapy did not demonstrate a significant clinical improvement compared to standard treatment (RR: 0.96; 95% CI: [0.74, 1.23], p = 0.73).

Allergic contact dermatitis to lip care cosmetic products - a systematic review.

Aim: Lip care cosmetics products are any external preparation used by people to prevent drying, chapping, dullness, and beautification of lips. This study aimed to review the literature on allergic reactions induced by different types of lip care cosmetic products. Methods: A literature search was performed in PubMed from inception to June 2022. The study included articles published in English and available in full text. References of illegible articles were searched. Studies describing any patient who developed allergic contact dermatitis after the application of lip care cosmetic products were included. Results: A total of 47 reports consisting of 58 individuals experienced allergic reactions to lip care products. Several lip care cosmetics products, such as lipsticks, lip balms, lip salve, lip gloss, lip liner, and lip plumper, were found to be associated with allergic reactions. The most common ingredients that caused the allergic contact dermatitis were castor oil, benzophenone-3, gallate, wax, and colophony. Conclusions: Lip care cosmetics products contain several components that have been associated with allergic reactions. Awareness needs to be created among the general public and dermatologists regarding the presence of possible allergens in lip care cosmetic products.

Serum Levels of Vitamins and Trace Elements in Patients with Visceral Leishmaniasis: a Systematic Review and Meta-analysis.

Visceral leishmaniasis (VL), a fatal disease prevalent in more than 70 countries, poses significant health challenges, particularly in poor communities with limited access to healthcare. Vitamins and trace elements play a crucial role in immune function and may influence susceptibility to VL. This systematic review and meta-analysis aimed to assess the differences in serum vitamin and trace element levels in VL patients compared to healthy individuals. We conducted an extensive search of databases (PubMed, Embase, and Google Scholar) to identify potentially eligible articles published from inception to June 2023. Data extraction and quality assessment were carried out by two reviewers independently. RevMan software (version 5.4) was used for analysis. Standardized mean difference (SMD) with a confidence interval (CI) of 95% was used to summarize the findings. Ten studies comprising 546 VL patients and 535 controls were included in our study. The findings revealed significantly reduced serum retinol levels in VL patients in comparison to controls (SMD: - 0.67; 95% CI: [- 1.05, - 0.28]; p = 0.0008). Serum zinc levels were also substantially lower in VL patients, regardless of controls recruited from endemic (SMD: - 2.65; 95% CI: [- 3.86, - 1.44]; p < 0.0001) or non-endemic regions (SMD: - 1.99; 95% CI: [- 3.02, - 0.96]; p < 0.0002). However, VL patients exhibited significantly increased serum copper levels compared to controls (SMD: 2.51; 95% CI: [0.70, 4.32]; p = 0.007). Patients with VL had lower serum levels of zinc and retinol and higher levels of copper, indicating a possible role of these micronutrients in influencing VL susceptibility and progression.

A Retrospective Observational Study on the Comparison of Different Diagnostic Modalities of Post-COVID Mucormycosis.

Background Mucormycosis, attributed to a group of molds known as mucormycosis, is a rare yet life-threatening fungal infection often colloquially referred to as black fungus. While its incidence notably surged during the second wave of COVID-19 infections in India, it's essential to recognize that mucormycosis was a significant concern even before the advent of the pandemic. Understanding the prevalence and characteristics of this infection in the pre-COVID era provides a crucial context for evaluating its impact and dynamics during the pandemic. Multiple diagnostic methods, such as potassium hydroxide (KOH) mount, culture, matrix-assisted laser desorption ionization-time of flight mass spectrometry (MALDI-TOF MS), and histopathological examination (HPE), are available for identifying this lethal infection. The primary objective of this study is to ascertain the sensitivity of various diagnostic methods for mucormycosis and to analyze the comparative effectiveness of microbiological versus histopathological diagnoses. Methods We conducted a retrospective observational study spanning six months, from May 2021 to October 2021, encompassing all mucormycosis cases meeting the inclusion criteria and diagnosed via histopathological examination (HPE) in the departments of pathology and microbiology. Microbiological tests were performed prior to the histopathological examinations. Sensitivity was assessed through statistical analysis, and the relationship between microbiological and histopathological diagnoses was evaluated using the chi-square test. Results Biopsy samples of 77 patients were collected, comprising 56 male and 21 female patients. Regarding age distribution, most patients fell within the 41-60 age bracket, while the smallest proportion was over 60 years old. The sensitivity and specificity of histopathological diagnosis, confirmed with periodic acid-Schiff (PAS) and Grocott-Gomori's methenamine silver (GMS) staining, both recorded a flawless 100%. KOH mount sensitivity stood at 88.3%, while fungal culture and MALDI-TOF exhibited sensitivities of 75.3%. Histopathological analysis revealed that 17% of cases displayed minimal fungal hyphae alongside necrotic tissue, whereas 58% exhibited abundant fungal hyphae accompanied by inflammatory cells. Additionally, absolute neutrophilia was observed in 55% of cases. Conclusions In our study, histopathology and KOH mount emerged as not only compassionate but also cost-effective diagnostic tools for identifying mucormycosis. The economic aspect of these diagnostic methods is highlighted in the results section to provide a comprehensive understanding of their cost-effectiveness. Additionally, we utilized MALDI-TOF MS as a straightforward, economically viable, and expeditious method specifically for confirming the fungal subtype in mucormycosis cases. The rationale behind choosing either MALDI-TOF MS or KOH for the diagnosis is elucidated, contributing to a clearer interpretation of our diagnostic approach. Furthermore, our findings indicate that absolute neutrophilia consistently manifests in 55% of mucormycosis cases.

Prediction of glaciated area fraction over the Sikkim Himalayan Region, India: a comparative study using response surface method, random forest, and artificial neural network.

Glacier area fraction at high altitude mountains is a serious worry in today's time triggered by climate change. The current information on this natural resource is very important for the survival of humanity as it affects the water, food, and energy security of people dependent on it. Due to its problematic accessibility and tough environmental condition, ground monitoring is quite challenging. This study investigates the impact of environmental parameters and pollutants on glacier area fraction over the Eastern Himalaya region and its prediction through random forest (RF), multilayer perceptron (MLP), radial basis function analysis (RBFN), and response surface methodology (RSM) models. The data are obtained from the Goddard Earth Sciences Data and Information Services Center (GES DISC), NASA's data archive portal ( https://giovanni.gsfc.nasa.gov ). The collinearity of independent variables reveals that all selected input parameters are highly correlated with R2 value > 0.9. The RSM and RF model provided valuable insight of the predictor's significance in addition to their capability to predict the response. The model performance was evaluated in terms of R2 value and the error matrices. The model's R2 value was found to be 0.843, 0.839, 0.838, and 0.743 for MLP, RBFN, RF, and RSM respectively. Although, the neural network model R2 values are the highest, but the most reliable and suitable model is RF as the error matrices for this model are much lower than others. This study encourages the investigation of the hybridization of these models for more accurate prediction.

Barriers to the effective management and prevention of post kala-azar dermal leishmaniasis (PKDL) in the Indian subcontinent.

Post kala-azar dermal leishmaniasis (PKDL) is a skin disease that usually occurs among individuals with a past history of visceral leishmaniasis (VL). PKDL cases act as a reservoir of parasites and may play a significant role in disease transmission. Hence, prompt detection and complete treatment of PKDL cases are crucial for the control and elimination of VL. The purpose of this review was to highlight the barriers to effective control and prevention of VL/PKDL as well as potential solutions in India. Main obstacles are lack of knowledge about the disease and its vector, poor treatment-seeking behaviours, ineffective vector control measures, lack of confirmatory diagnostics in endemic areas, limited drug choices, treatment noncompliance among patients, drug resistance, and a lack of an adequate number of trained personnel in the health system. Therefore, in order to control and successfully eliminate VL in the Indian subcontinent, early detection of PKDL cases, improved diagnosis and treatment, raising awareness, and effective vector control mechanisms are necessary.

Rice WRKY13 TF protein binds to motifs in the promoter region to regulate downstream disease resistance-related genes.

In plants, pathogen resistance is brought about by the binding of certain transcription factor (TF) proteins to the cis-elements of certain target genes. These cis-elements are present upstream in the motif of the promoters of each gene. This ensures the binding of a specific TF to a specific promoter, therefore regulating the expression of that gene. Therefore, the study of each promoter sequence of all the rice genes would help identify the target genes of a specific TF. Rice 1 kb upstream promoter sequences of 55,986 annotated genes were analyzed using the Perl program algorithm to detect WRKY13 binding motifs (bm). The resulting genes were grouped using Gene Ontology and gene set enrichment analysis. A gene with more than 4 TF bm in their promoter was selected. Ten genes reported to have a role in rice disease resistance were selected for further analysis. Cis-acting regulatory element analysis was carried out to find the cis-elements and confirm the presence of the corresponding motifs in the promoter sequences of these genes. The 3D structure of WRKY13 TF and the corresponding ten genes were built, and the interacting residues were determined. The binding capacity of WRKY13 to the promoter of these selected genes was analyzed using docking studies. WRKY13 was considered for docking analysis based on the prior reports of autoregulation. Molecular dynamic simulations provided more details regarding the interactions. Expression data revealed the expression of the genes that helped provide the mechanism of interaction. Further co-expression network helped to characterize the interaction of these selected disease resistance-related genes with the WRKY13 TF protein. This study suggests downstream target genes that are regulated by the WRKY13 TF. The molecular mechanism involving the gene network regulated by WRKY13 TF in disease resistance against rice fungal pathogens is explored.
