Safety Assessment of Streptococcus salivarius UBSS-01 in Rats and Double-Blind Placebo-Controlled Study in Healthy Individuals.

Streptococcus salivarius is a common, harmless, and prevalent member of the oral microbiota in humans. In the present study, the safety of S. salivarius UBSS-01 was evaluated using in silico methods and preclinical and clinical studies. In an acute toxicity study, rats were administered with 5 g/kg (500 × 109 CFU) S. salivarius UBSS-01. The changes in phenotypic behaviors and hematological, biochemical, electrolytes, and urine analyses were monitored. No toxicity was observed at 14 days post-treatment. The no observable effects limit (NOEL) of S. salivarius UBSS-01 was >5 g/kg in rats. In a 28-day repeat dose toxicity study, rats were administered S. salivarius UBSS-01 once daily at doses of 0.1, 0.5, and 1 g/kg (10, 50, and 100 billion CFU/kg, respectively) body weight. S. salivarius UBSS-01 did not influence any of the hematology parameters and clinical chemistry parameters in plasma and serum samples after 28-day repeated administration. No structural abnormality was observed in the histological examination of organs. Whole genome analysis revealed the absence of virulence factors or genes that may transmit antibiotic resistance. In the double-blind study with 60 human participants (aged 18-60 years), consumption of S. salivarius UBSS-01 for 30 days was found to be safe and results were comparable with placebo treatment These findings indicate that S. salivarius UBSS-01 may be safe for human consumption.

Reliable Prostate Cancer Risk Mapping From MRI Using Targeted and Systematic Core Needle Biopsy Histopathology.

OBJECTIVE: To compute a dense prostate cancer risk map for the individual patient post-biopsy from magnetic resonance imaging (MRI) and to provide a more reliable evaluation of its fitness in prostate regions that were not identified as suspicious for cancer by a human-reader in pre- and intra-biopsy imaging analysis. METHODS: Low-level pre-biopsy MRI biomarkers from targeted and non-targeted biopsy locations were extracted and statistically tested for representativeness against biomarkers from non-biopsied prostate regions. A probabilistic machine learning classifier was optimized to map biomarkers to their core-level pathology, followed by extrapolation of pathology scores to non-biopsied prostate regions. Goodness-of-fit was assessed at targeted and non-targeted biopsy locations for the post-biopsy individual patient. RESULTS: Our experiments showed high predictability of imaging biomarkers in differentiating histopathology scores in thousands of non-targeted core-biopsy locations (ROC-AUCs: 0.85-0.88), but also high variability between patients (Median ROC-AUC [IQR]: 0.81-0.89 [0.29-0.40]). CONCLUSION: The sparseness of prostate biopsy data makes the validation of a whole gland risk mapping a non-trivial task. Previous studies i) focused on targeted-biopsy locations although biopsy-specimens drawn from systematically scattered locations across the prostate constitute a more representative sample to non-biopsied regions, and ii) estimated prediction-power across predicted instances (e.g., biopsy specimens) with no patient distinction, which may lead to unreliable estimation of model fitness to the individual patient due to variation between patients in instance count, imaging characteristics, and pathologies. SIGNIFICANCE: This study proposes a personalized whole-gland prostate cancer risk mapping post-biopsy to allow clinicians to better stage and personalize focal therapy treatment plans.

INTEGRATING PROSTATE SPECIFIC ANTIGEN DENSITY BIOMARKER INTO DEEP LEARNING PROSTATE MRI LESION SEGMENTATION MODELS.

Prostate cancer lesion segmentation in multi-parametric magnetic resonance imaging (mpMRI) is crucial for pre-biopsy diagnosis and targeted biopsy guidance. Deep convolution neural networks have been widely utilized for lesion segmentation. However, these methods fail to achieve a high Dice coefficient because of the large variations in lesion size and location within the gland. To address this problem, we integrate the clinically-meaningful prostate specific antigen density (PSAD) biomarker into the deep learning model using feature-wise transformations to condition the features in latent space, and thus control the size of lesion prediction. We tested our models on a public dataset with 214 annotated mpMRI scans and compared the segmentation performance to a baseline 3D U-Net model. Results demonstrate that integrating the PSAD biomarker significantly improves segmentation performance in both Dice coefficient and centroid distance metric.

Social Determinants Predicting the Community Pharmacists' Workforce Preparedness for, and Response to, the Public Health Emergencies.

OBJECTIVES: To identify the predicting factors that contribute to preparedness for public health emergencies among community pharmacists in India. METHODS: Multistage cluster sampling was done. The geographic breakdown was done based on villages and areas and used as clusters. A simple random method was done in the first stage to select the villages as clusters. From each selected village, a simple random method was done in the second stage to select the areas. From each selected area, all the community pharmacies were selected. The survey questionnaire had 3 sections with 43 items: (A) demographic information, (B) preparedness, (C) response toward infectious diseases. The participants chose "Yes/No", in sections B and C. A score of 1 was given for "Yes", and a score of zero was given for "No". RESULTS: Multiple correlation analyses were conducted between participants' preparedness and response (PR) scores and independent variables. The independent variables such as "More than one Pharmacist working in a pharmacy", "Pharmacists who are trained more than once on disaster management", and encountered more than 1 patient with the infectious disease were positively and significantly correlated with the dependent variable (PR scores). CONCLUSIONS: Community pharmacists were aware of the issues they may face in their community concerning public health emergencies. They believed that the medications available in their pharmacy are sufficient to face any emergency. They could identify the clinical manifestations of public health emergency conditions and provide counselling to the customers toward them. Community pharmacists who were trained more than once in disaster management were the strongest predicting factor.

A novel multi-modality imaging phantom for validating interstitial needle guidance for high dose rate gynecological brachytherapy.

PURPOSE: To design, manufacture, and validate a female pelvic phantom for multi-modality imaging (CT, MRI, US) to benchmark a commercial needle tracking system with application in HDR gynecological (GYN) interstitial procedures. MATERIALS AND METHODS: A GYN needle-tracking phantom was designed using CAD software to model an average uterus from a previous patient study, a vaginal canal from speculum dimensions, and a rectum to accommodate a transrectal ultrasound (TRUS) probe. A target volume (CTVHR ) was designed as an extension from the cervix-uterus complex. Negative space molds were created from modeled anatomy and 3D printed. Silicone was used to cast the anatomy molds. A 3D printed box was constructed to house the manufactured anatomy for structural integrity and to accommodate the insertion of a speculum, tandem, needles, and TRUS probe. The phantom was CT-imaged to identify potential imperfections that might impact US visualization. Free-hand TRUS was used to guide interstitial needles into the phantom. The commercial tracking system was used to generate a 3D US volume. After insertion, the phantom was imaged with CT and MR and the uterus and CTVHR dimensions were verified against the CAD model. RESULTS/CONCLUSIONS: The manufactured phantom allows for accurate visualization with multiple imaging modalities and is conducive to applicator and needle insertion. The phantom dimensions from the CAD model were verified with those from each imaging modality. The phantom is low cost and can be reproducibly manufactured with the 3D printing and molding processes. Our initial experiments demonstrate the ability to integrate the phantom with a commercial tracking system for future needle tracking validation studies.

Metronidazole induced cutaneous adverse drug reaction- a systematic review of descriptive studies.

BACKGROUND: A substantial number of research studies on metronidazole-related cutaneous symptoms have recently been published. Our objective was to identify and evaluate descriptive studies that described metronidazole-related skin manifestations, therapeutic interventions, and consequences. METHODOLOGY: A comprehensive literature search was carried out in the PubMed, Scopus, and grey literature databases from inception to April 2022 without any constraints, as well as a snowball search in Google and a search in Google Scholar. Descriptive articles describing metronidazole-related cutaneous manifestations were considered for the review. Two distinct reviewers carried out the research selection, data extraction, and quality assessment; any discrepancies were resolved by consensus with the third reviewer. RESULTS: About 24 out of 4648 descriptive studies, including 26 patients (20 Female patients and 6 male patients), were included in this review. The included studies comprised a range of ages from 16 to 78 years old. Metronidazole was indicated for the treatment of bacterial vaginosis, trichomoniasis, sepsis, anti-infection therapy, perforated appendicitis, rosacea, vaginal discharge, dysentery, acne rosacea, trichomonal vaginitis, lichen planus, liver abscess, facial rosacea, intestinal amoebiasis, and gingivitis. Fixed drug eruption was the most common skin manifestation which was reported in 7 cases included in this review. Cutaneous manifestations were ameliorated by cessation of the offending drug and by apportioning antihistamines, topical steroids, parenteral corticosteroids, emollients, and topical moisturizers. CONCLUSION: Clinicians and healthcare professionals should be cognizant of the potential cutaneous adverse drug reactions (CADRs) induced by metronidazole to mitigate fatal circumstances. The management of the CADRs appears to respond effectively with immediate drug discontinuation and supportive therapy.

Atrial Fibrillation Ablation-induced Pulmonary Venous Occlusion Requiring Pneumonectomy.

A 71-year-old woman with a history of atrial fibrillation underwent a catheter-based ablation procedure. Months later, she presented with dyspnea and a left-sided pleural effusion. Diagnostic evaluation revealed left-sided pulmonary venous occlusion, with essentially absent left lung perfusion. The patient underwent left pneumonectomy, with left atrial appendage occlusion. Although lobectomy for pulmonary venous occlusion of a single vein after pulmonary vein isolation has been described, this appears to be a novel report of occluded pulmonary venous drainage of an entire lung necessitating pneumonectomy.

Knowledge and attitudes toward the COVID-19 vaccine among India's general rural population.

Introduction: Even after the enforcement of the lockdown, the government was unable to control the spread of the COVID-19 infection. Vaccination is the only remaining hope for preventing and controlling COVID-19 infections. The knowledge and attitude of the recipients can influence vaccine acceptance. In this study, we aim to assess the knowledge and attitude toward the COVID-19 vaccine among the general rural population of India. Methodology: A community-based, prospective, cross-sectional study was conducted from May 2021 to October 2021 in the rural part of the Mandya district of Karnataka, India. Individuals over the age of 18 who met the Ministry of Health and Family Welfare's vaccination eligibility criteria were included in the study. Demographic details of participants and assessment of knowledge and attitude towards the COVID-19 vaccine were done in a designed and validated data collection form. Results: The study included 596 participants, with females dominating males by 54.9 % (327). The average age of the participants was 31 years. Among them, 81.71% (487) had adequate knowledge, and 81.5% (486) had a positive attitude towards the COVID-19 vaccine. Females (85.3%, 279) tend to have a more positive attitude than males (77%, 207). Positive attitude participants (86.86 %, 423) have a higher level of knowledge about the COVID-19 vaccine than negative attitude participants (57.79 %, 63). Conclusion: In the study, we found that 81.71% had adequate knowledge and 81.5% had a positive attitude toward the COVID-19 vaccine.

Introducción: Incluso tras la obligatoriedad del confinamiento el gobierno fue incapaz de controlar la propagación de la infección por COVID-19.

Conclusión: En el estudio, encontramos que el 81,71% tuvo un conocimiento adecuado, y el 81,5% una actitud positiva hacia la vacuna contra la COVID-19.

Catheter-associated urinary tract infection: an overview.

CAUTIs (catheter-associated urinary tract infections) continue to be one of the most common health-care-related illnesses in the entire globe. CAUTIs are the cause of 40% of all hospital-acquired infections and 80% of all nosocomial urinary tract infections (UTIs). A urine catheter is implanted into a high percentage of inpatients at some point during their hospitalization, and indwelling urinary catheter adoption likely to be on the rise. Urinary catheters, made of plastic materials, inhibit the urinary tract's natural defence mechanisms and enhance the bacterial colonization or biofilm formation on the catheter surface, which may cause CAUTIs. It is associated with increased burden of disease, mortality, hospital bills and length of hospital stay. Therefore, to prevent these infections, technological innovations in catheter materials that limit biofilm formation will be required. Unfortunately, many health-care practitioners are unclear of the precise indications for bladder catheterization and accurate CAUTI criteria, which can lead to unnecessary catheterization, antibiotic overuse for asymptomatic bacteriuria and the spread of resistant organisms. As a result, we discuss CAUTIs in general, including definitions, pathophysiology, causation, indications for catheterization and a variety of effective CAUTI-fighting strategies.

Role of human leukocyte antigen in anti-epileptic drugs-induced Stevens-Johnson Syndrome/toxic epidermal necrolysis: A meta-analysis.

PURPOSE: Antiepileptic drugs (AEDs) are extensively used to manage epilepsy and other comorbidities associated with seizures. Human Leukocyte Antigen (HLA) has a strong association with AED-induced severe cutaneous adverse drug reactions. OBJECTIVE: We aimed to perform a systematic review and meta-analysis to identify, critically evaluate, and synthesize the best possible evidence on HLA-associated AED-induced Stevens-Johnson Syndrome/Toxic Epidermal Necrolysis (SJS/TEN). METHODS: MEDLINE/PubMed, Scopus, and the Cochrane Library were searched for literature from inception up to July 2022. We included case control studies analyzing association between HLA and AED-induced SJS/TEN. We assessed the studies' risk of bias in using Quality of genetic studies (Q-genie) tool. Outcomes focused on association (risk) between HLA and AED-induced SJS/TEN. The estimated risk was presented in the form of odds ratio (OR). RESULTS: We included 37 studies (51,422 participants; 7027 cases and 44,395 controls). There was a significantly higher risk of Carbamazepine-induced SJS/TEN with HLA-A (OR: 1.50; 95% CI: 1.03 to 2.17), HLA-B (OR: 1.94; 95% CI: 1.45 to 2.58), HLA-C (OR: 7.83; 95% CI: 4.72 to 12.98), and HLA-DRB1 (OR: 2.82; 95% CI: 1.94 to 4.12). Lamotrigine-induced SJS/TEN posed a higher risk with HLA-A (OR: 2.38; 95% CI: 1.26 to 4.46) and HLA-B (OR: 2.79; 95% CI: 1.75 to 4.46). Phenytoin-induced SJS/TEN showed a higher risk with HLA-A (OR: 3.47; 95% CI: 2.17 to 5.56), HLA-B (OR: 1.72; 95% CI: 1.38 to 2.15), and HLA-C (OR: 2.92; 95% CI: 1.77 to 4.83). Phenobarbital-induced SJS/TEN had a higher risk with HLA-A (OR: 6.98; 95% CI: 1.81 to 26.84), HLA-B (OR: 2.40; 95% CI: 1.39 to 4.17), and HLA-C (OR: 3.37; 95% CI: 1.03 to 11.01). Zonisamide-induced SJS/TEN was significantly associated with HLA-A*02:07 (OR: 9.77; 95% CI: 3.07 to 31.1), HLA-B*46:01 (OR: 6.73; 95% CI: 2.12 to 21.36), and HLA-DRB1×08:03 (OR: 3.78; 95% CI: 1.20 to 11.97). All other alleles of HLA were observed to have a non-significant association with AED-induced SJS/TEN. All included studies were of good quality, with a score of >50 and a mean score of 54.96 out of 77. CONCLUSION: Our study showed a significant association between few variants of HLA alleles and AED-induced SJS/TEN. Evidences from our study could help in population-based studies and in implementation of individualized treatment regimens. These findings could be part of translational research helping in precision therapy.

The prevalence of inverse health consequences of COVID-19 vaccines: A post-vaccination study.

Background: COVID-19 vaccinations are intended to help produce neutralizing antibodies which target surface spike protein to combat the SARS-Cov-2 virus. Similarly, COVID-19 recovered patients exhibit high levels of SARS-CoV-2 neutralizing antibodies, which predominantly target the surface spike protein and are associated with the occurrence of health consequences in survivors. Objective: The aim of the study is to explore the long-term health consequences of the COVID-19 vaccines. Methodology: A prospective, exploratory observational study conducted both online and offline using various questionnaires with all immunized individuals who had been inoculated for at least a month following their last COVID-19 vaccine either AZD1222® or BBV152® vaccines. Results: We evaluated 258 individuals who had taken the COVID vaccine and found that females made up the majority (54.3%) and that the mean age was 24 years. Post-vaccination long-term health issues were reported by 36.05% (93) of the participants, with 37.86% (53) of females and 33.9% (40) of males (p = 0.292). Myalgia was reported by 20.15% (52), fatigue was 13.95% (36), paresthesia was 1.16% (3), ageusia was 0.77% (2), sadness/irritability was 2.31% (6), and lack of concentration/excessive worry was 3.1% (8). Conclusions: Myalgia, fatigue, paresthesia, ageusia, coughs and colds, dyspnea, sadness/irritability, and lack of concentration/excessive worry are health consequences related to the COVID-19 vaccination which follow a similar pattern of post-COVID syndrome.

Antecedentes: El objetivo de las vacunas frente a la COVID-19 es el de ayudar a producir anticuerpos neutralizantes dirigidos a la proteína de la espícula para combatir el virus SARS-Cov-2. De igual modo, los pacientes que se recuperan de la COVID-19 exhiben grandes niveles de anticuerpos neutralizantes de SARS-CoV-2, que se dirigen predominantemente a la superficie de la proteína de la espícula, y están asociados a la incidencia de consecuencias para la salud de los sobrevivientes. Objetivo: El objetivo del estudio es explorar las consecuencias para la salud a largo plazo de las vacunas frente a la COVID-19. Metodología: Estudio prospectivo, exploratorio y observacional realizado tanto online como offline, utilizando diversos cuestionarios con todos los individuos vacunados a quienes se había inoculado en el plazo de al menos un mes, tras la última vacuna frente a la COVID-19, bien fueran las vacunas AZD1222® o BBV152®. Resultados: Evaluamos a 258 individuos que habían recibido la vacuna frente a la COVID, y encontramos que la mayoría eran mujeres (54,3%) con una edad media de 24 años. Las cuestiones de salud a largo plazo, tras la vacuna, fueron reportadas por un 36,05% (93) de los participantes, con un 37,86% (53) de mujeres y un 33.9% (40) de varones (p = 0,292). Se reportó mialgia en el 20,15% (52) de los casos, fatiga en el 13,95% (36), parestesia en el 1,16% (3), ageusia en el 0,77% (2), tristeza/irritabilidad en el 2,31% (6), y falta de concentración/preocupación excesiva en el 3,1% (8). Conclusiones: Mialgia, fatiga, parestesia, ageusia, tos y resfriado, disnea, tristeza/irritabilidad, y falta de concentración/preocupación excesiva son las consecuencias de salud relacionadas con la vacuna frente a la COVID-19, y siguen un patrón similar al del síndrome post-COVID.

Rasburicase induced methemoglobinemia: A systematic review of descriptive studies.

PURPOSE: There is an increased number of reports being published on rasburicase-induced methemoglobinemia recently. We aimed to identify and critically evaluate all the descriptive studies that described the rasburicase-induced methemoglobinemia, its treatment approach, and their outcomes. METHODOLOGY: PubMed, Scopus and grey literature databases were searched from inception to January 2022 using search terms "rasburicase" and "methemoglobinemia" without any language and date restriction. A bibliographic search was also done to find additional studies. Only descriptive studies on Rasburicase-induced methemoglobinemia were included for our review. Two contributors worked independently on study selection, data abstraction, and quality assessment, and any disagreements were resolved by consensus or discussion with a third reviewer. RESULT: A total of 24 reports including 27 patients (23 male, 3 female patients, and 1 study did not specify the gender of the patient) aged from 5 to 75 years were included in the review. Immediate withdrawal of the drug and administering methylene blue, ascorbic acid, blood transfusion, and supportive oxygen therapy are the cornerstone in the management of rasburicase-induced methemoglobinemia. CONCLUSION: Rasburicase administration should be followed by careful monitoring of patients for any severe complication and treat it as early as possible appropriately. In a patient who presents with rasburicase-induced haemolysis or methemoglobinemia, it is often important to expect a diagnosis of G6PD deficiency unless otherwise confirmed and to avoid administering methylene blue, even though the patient is from a low-risk ethnicity for G6PDD.

Catheter ablation for atrial fibrillation can be safely performed without invasive hemodynamic monitoring: A multi-center study.

BACKGROUND: Arterial invasive monitoring is the most common method in the USA for hemodynamic monitoring during atrial fibrillation (AF) ablation. Although studies have shown favorable comparison between non-invasive and invasive hemodynamic monitoring (IHM) in non-cardiac procedures under general anesthesia, limited data is available for complex cardiac procedures such as AF ablation in the USA. With progressive improvement in AF ablation procedural safety, particularly with routine use of intracardiac echocardiography (ICE) to monitor for pericardial effusion, it is unclear if invasive hemodynamic monitoring provides any advantage over non-invasive methods. Therefore, the purpose of this study is to determine whether noninvasive hemodynamic monitoring is non-inferior to invasive hemodynamic monitoring during AF ablation under general anesthesia in patients without major cardiac structural abnormality. METHODS: A multi-center retrospective data of AF ablation from July 2019 to December 2020 was extracted. A total of three hundred and sixty-two patients (362) were included, which were divided into group A (non-invasive hemodynamic monitoring) and group B (invasive hemodynamic monitoring). The primary outcome was to compare procedural safety between the two groups. RESULTS: Out of 362 patients, 184 (51%) received non-invasive and 178 (49%) received invasive hemodynamic monitoring with similar baseline characteristics. There was no significant difference between the two groups in complication rates (groin hematoma, pericardial effusion, cardiac tamponade). Mean procedure time was longer in group B with 3.35% arterial site discomfort. Urgent arterial access was required in only 1 patient in group A. CONCLUSION: This retrospective multicenter study strongly suggests that catheter ablation for atrial fibrillation under general anesthesia can be safely performed with noninvasive hemodynamic monitoring without requiring arterial access, with potential benefit in procedural duration and cost.

Atlas-based Semantic Segmentation of Prostate Zones.

Segmentation of the prostate into specific anatomical zones is important for radiological assessment of prostate cancer in magnetic resonance imaging (MRI). Of particular interest is segmenting the prostate into two regions of interest: the central gland (CG) and peripheral zone (PZ). In this paper, we propose to integrate an anatomical atlas of prostate zone shape into a deep learning semantic segmentation framework to segment the CG and PZ in T2-weighted MRI. Our approach incorporates anatomical information in the form of a probabilistic prostate zone atlas and utilizes a dynamically controlled hyperparameter to combine the atlas with the semantic segmentation result. In addition to providing significantly improved segmentation performance, this hyperparameter is capable of being dynamically adjusted during the inference stage to provide users with a mechanism to refine the segmentation. We validate our approach using an external test dataset and demonstrate Dice similarity coefficient values (mean±SD) of 0.91±0.05 for the CG and 0.77±0.16 for the PZ that significantly improves upon the baseline segmentation results without the atlas. All code is publicly available on GitHub: https://github.com/OnofreyLab/prostate_atlas_segm_miccai2022.

The rise in antimicrobial resistance: An obscure issue in COVID-19 treatment.

A saturated health care system with a lack of evidence-based antiviral medicine and ignorance of antimicrobial stewardship during pandemics has prompted clinicians to prescribe a broad-spectrum antibiotic more often. A prospective, cross-sectional study of COVID-infected patients was conducted to gain insight into antibiotic prescribing practices and their impact on antimicrobial resistance. The antibiotic susceptibility test was performed using the disc diffusion method. 318 patients met the study's inclusion criteria, with a mean age of 46 years and 55% (175) of them being males. Antibiotics were prescribed for 93.72% (209) of mild cases, 92.45% (49) of moderate cases, 96.15% (25) of severe cases, and 100% (16) of critical cases of COVID-19. A total of 95 samples were sent in for culture and antibiotic sensitivity testing, with 58.95% (56) confirming growth. The majority of the growth was found to contain E. coli (14). In 54.9% of cases, antibiotics with less than 50% sensitivity to curing bacterial infection were detected. In the study, we found that antibiotics were being used unnecessarily in excessive quantities and that more than half of the antibiotics were less sensitive to isolated bacteria.

Methotrexate related cutaneous adverse drug reactions: a systematic literature review.

OBJECTIVES: Recently, there is an increased number of reports being published on Methotrexate (MTX) related cutaneous manifestations. We aimed to identify and critically appraise descriptive studies describing the MTX related skin manifestations, treatment approach, and their outcomes. METHODOLOGY: An extensive literature search was performed in the PubMed, Embase, and Scopus databases from inception to April 2021 without any restrictions along with the bibliographic search of included studies, grey literature search, and a snowball search was performed in Google and Google Scholar to identify the relevant literature. Descriptive studies reporting MTX related cutaneous manifestations were considered for the review. The study selection, data extraction, and quality assessment were conducted by two independent reviewers and any disagreements were settled by consensus with the third reviewer. RESULTS: 31 out of 8,365 descriptive studies including 38 patients (22 females and 16 males) aged between 12 and 78 years prescribed for the management of rheumatoid arthritis, ankylosing spondylitis, and psoriasis were included in this review. Toxic epidermal necrolysis (TEN), papular eruption, vasculitis, erosions of psoriasis, ulcerated psoriatic plaques, local reactions, keratinocyte dystrophy, erythema multiforme, drug rash with eosinophilia and systemic symptoms, Steven Johnson syndrome and photosensitive dermatitis were the majority of MTX induced cutaneous reactions. Immediate withdrawal of MTX, providing appropriate care with anti-inflammatory, topical steroids, and supplementation with folic acid were reported to be effective for the management of the MTX related cutaneous manifestations. CONCLUSIONS: Clinicians and healthcare professionals should be aware of possible acute cutaneous drug reactions induced by MTX to avoid further consequences and fatal conditions. Immediate withdrawal of MTX and supportive care were reported as an efficacious therapeutic management of acute cutaneous drug reactions. PROSPERO REGISTRATION NUMBER: CRD42020220038.

Effect of Multi-strain Probiotic Formulation on Students Facing Examination Stress: a Double-Blind, Placebo-Controlled Study.

In this placebo-controlled, double-blind clinical trial, we have investigated the effect of multi-strain probiotic (Bacillus coagulans Unique IS2, Lactobacillus rhamnosus UBLR58, Bifidobacterium lactis UBBLa70, Lactobacillus plantarum UBLP40 (each of 2 billion CFU); Bifidobacterium breve UBBr01, Bifidobacterium infantis UBBI01 (each of 1 billion CFU)) capsule with glutamine (250 mg) on students facing examination stress. A total of 80 students (18-24 years) were enrolled and randomised to receive multi-strain probiotic or placebo capsules twice a day for 28 days (i.e. pre- and during examination). The stress was analysed at the baseline and the end of the treatment by using the perceived stress scale (PSS), depression anxiety stress scale (DASS), and state-trait anxiety inventory (STAI) questionnaire. The serum cortisol levels were also determined. As a result, at the end of the trial, a total of 74 students completed the study, and those who consumed probiotic capsules showed a significant reduction in PSS, DASS, and STAI scores, and serum cortisol levels from the baseline as compared with placebo. No adverse events were reported during the study. In conclusion, the multi-strain probiotic is effective in reducing stress associated with examination. CTRI/2019/03/018178.

Knowledge and beliefs towards universal safety precautions during the coronavirus disease (COVID-19) pandemic among the Indian public: a web-based cross-sectional survey.

Background: The novel coronavirus disease 2019 (COVID-19) is considered the most serious global health threat in recent times. As there is a current lack of approved treatments and vaccines, universal safety precautions (USPs) must be taken to deal with this emergency. Objective: The aim of this study was to assess the knowledge and beliefs of the Indian public with regard to USPs during the COVID-19 pandemic. Methods: A cross-sectional, web-based survey was conducted during March 2020. A 20-item self-administered questionnaire was developed, validated and distributed using Google Forms through social media networks. Binary logistic regression analysis was used to identify the factors influencing knowledge regarding COVID-19 USPs. Results: Of the 1117 individuals who participated in the survey, the mean age was 28.8 ± 10.9 years, 32.9% had a post-graduate education, 45% had a professional job, and 40% belonged to the upper-middle economic class. Overall, the mean correct response scores were 63% for USP knowledge and 83% for USP beliefs. All the sociodemographic variables were significantly (p < 0.001) associated with the USP knowledge levels. Importantly, students were less likely to have a lower level of USP knowledge compared with the other occupations (odds ratio 0.35, 95% CI 0.23-0.53; p < 0.001). Conclusion: Although the knowledge and beliefs of the Indian public towards USPs are encouraging, there is a need for long-term educational interventions as the dynamics and severity of COVID-19 rapidly change. These findings could guide public health authorities to make and implement precautionary measures to combat this pandemic.

Inappropriate Medication Use and Cost Comparison Analysis of Proton Pump Inhibitors: Evidence from an Indian Tertiary Care Facility.

RATIONALE AND OBJECTIVE: Proton pump inhibitor (PPI) is one of the most widely prescribed medicines and commonly used in gastric related disorders and there is a huge need to analyze the irrational use of PPI in a country like India. The present study was designed to describe the rational drug use and cost comparison analysis of PPI in a rural tertiary care hospital. METHODOLOGY: A prospective observational study was performed among 253 inpatients for a period of 9 months after getting ethical approval. Those who received the PPIs for any of its indications were included in the study without any gender or age restriction. US FDA guidelines were used to analyse the appropriateness of the drug use and cost comparison analysis of the branded versus generic PPIs was also performed. FINDINGS: Among the 253 inpatients, the majority (62%) were male and the mean age was 46±19 years. Mean hospital stay and the number of drugs in prescription were found to be 4.0 ± 1days 4.39 ±1.16 items, respectively. Pantoprazole (76%) was the most prescribed PPI even though the majority (57%) of the patients treated outside the FDA approved indication. Drug interaction has been reported in 14% and ADR in 9% of the population. The average cost of hospital stay estimated as 207.96+149.57 INR, and potential cost saving of INR 41582 was observed with generic replacement. CONCLUSION: The study inferred irrational drug use of PPI still prevalent, that too without considering the economic impact of it on general populations. Healthcare practitioners should be aware and cautious while prescribing the PPI to identify the actual need and to choose the most cost-effective alternative 1.
