RESUMEN
OBJECTIVES: India has taken several initiatives to provide health care to its population while keeping the related expenditure minimum. Since cardiovascular diseases are the most prevalent chronic conditions, in the present study, we aimed to analyze the difference in prices of medicines prescribed for three cardiovascular risk factors, based on (a) listed and not listed in the National List of Essential Medicines (NLEM) and (b) generic and branded drugs. MATERIALS AND METHODS: Outpatient prescriptions for diabetes mellitus, hypertension, and dyslipidemia were retrospectively analyzed from 12 tertiary centers. The prices of medicines prescribed were compared based on presence or absence in NLEM India-2015 and prescribing by generic versus brand name. The price was standardized and presented as average price per medicine per year for a given medicine. The results are presented in Indian rupee (INR) and as median (range). RESULTS: Of the 4,736 prescriptions collected, 843 contained oral antidiabetic, antihypertensive, and/or hypolipidemic medicines. The price per medicine per year for NLEM oral antidiabetics was INR 2849 (2593-3104) and for non-NLEM was INR 5343 (2964-14364). It was INR 806 (243-2132) for generic and INR 3809 (1968-14364) for branded antidiabetics. Antihypertensives and hypolipidemics followed the trend. The price of branded non-NLEM medicines was 5-22 times higher compared to generic NLEM which, for a population of 1.37 billion, would translate to a potential saving of 346.8 billion INR for statins. The variability was significant for sulfonylureas, angiotensin receptor blockers, beta-blockers, diuretics, and statins (P < 0.0001). CONCLUSION: The study highlights an urgent need for intervention to actualize the maximum benefit of government policies and minimize the out-of-pocket expenditure on medicines.

BACKGROUND OBJECTIVES: Irrational prescribing practices have major consequences on patient safety and also increase the economic burden. Real-life examples of impact of irrational prescription have potential to improve prescribing practices. In this context, the present study aimed to capture and evaluate the prevalence of deviations from treatment guidelines in the prescriptions, potential consequence/s of the deviations and corrective actions recommended by clinicians. METHODS: It was a cross-sectional observational study conducted in the outpatient departments of tertiary care hospitals in India wherein the 13 Indian Council of Medical Research Rational Use of Medicines Centres are located. Prescriptions not compliant with the standard treatment guidelines and incomplete prescriptions with respect to formulation, dose, duration and frequency were labelled as 'prescriptions having deviations'. A deviation that could result in a drug interaction, lack of response, increased cost, preventable adverse drug reaction (ADR) and/or antimicrobial resistance was labelled as an 'unacceptable deviation'. RESULTS: Against all the prescriptions assessed, about one tenth of them (475/4838; 9.8%) had unacceptable deviations. However, in 2667/4838 (55.1%) prescriptions, the clinicians had adhered to the treatment guidelines. Two thousand one hundred and seventy-one prescriptions had deviations, of which 475 (21.9%) had unacceptable deviations with pantoprazole (n=54), rabeprazole+domperidone (n=35) and oral enzyme preparations (n=24) as the most frequently prescribed drugs and upper respiratory tract infection (URTI) and hypertension as most common diseases with unacceptable deviations. The potential consequences of deviations were increase in cost (n=301), ADRs (n=254), drug interactions (n=81), lack of therapeutic response (n=77) and antimicrobial resistance (n=72). Major corrective actions proposed for consideration were issuance of an administrative order (n=196) and conducting online training programme (n=108). INTERPRETATION CONCLUSIONS: The overall prevalence of deviations found was 45 per cent of which unacceptable deviations was estimated to be 9.8 per cent. To minimize the deviations, clinicians recommended online training on rational prescribing and administrative directives as potential interventions.

Background: Various innovative teaching methods have been designed in an attempt to provide millennial students an interactive and stimulating learning environment. A jigsaw method is one such form of cooperative learning that enables students to develop critical-thinking and ability for effective communication and promotes positive student attitudes toward their own learning. The present study was thus undertaken to introduce a jigsaw-based cooperative learning method and to understand the perception of the students and faculty. Methodology: This was a cross-sectional study conducted among second year MBBS students. Students were randomly divided into 10 parent groups, with 10 students each. The topic was divided into 10 subtopics. Each student in the parent group was allotted a sub-topic. The students who were given the same sub-topic assembled to form an expert group. They interacted and discussed the subtopic. Students finally returned to their parent groups for peer teaching and presentation. A validated questionnaire was used to gather students and faculty feedback. Descriptive statistics were used to analyze responses to the Likert scale questions. Qualitative data was analyzed using thematic analysis. Results: The present study included 95 s year MBBS students. Majority (81%) students agreed that this teaching learning method enhanced their communication skills. Seventy-five percent of the students agreed that the activity helped in overcoming shyness and hesitation in the class. Overall the faculty also agreed that the jigsaw method was helpful for the students. Conclusions: Cooperative learning like jigsaw facilitates learning allowing student-student discussion, improving communication and teaching skills.

These findings underscore the importance of exploring microbial biodiversity for the discovery of novel antimicrobial agents. This study contributes to the growing knowledge of microbial secondary metabolites with potential therapeutic value.
RESUMEN
OBJECTIVE: The rational use of medicines as per the World Health Organization (WHO) should be practiced globally. However, data regarding the completeness of the prescriptions and their rational use is lacking from developing countries like India. Thus, the aim of this study was to assess the prescribing patterns of drugs and completeness of prescriptions as per WHO core drug use and complementary indicators to provide real-life examples for the Indian Council of Medical Research (ICMR) online prescribing skill course for medical graduates. METHODS: Prescriptions of the patients, fulfilling inclusion criteria, attending Outpatient Departments of various specialties of tertiary care hospitals, were collected by thirteen ICMR Rational use of medicines centers located in tertiary care hospitals, throughout India. Prescriptions were evaluated for rational use of medicines according to the WHO guidelines and for appropriateness as per standard treatment guidelines using a common protocol approved by local Ethics committees. RESULTS: Among 4838 prescriptions, an average of about three drugs (3.34) was prescribed to the patients per prescription. Polypharmacy was noted in 83.05% of prescriptions. Generic drugs were prescribed in 47.58% of the prescriptions. Further, antimicrobials were prescribed in 17.63% of the prescriptions and only 4.98% of prescriptions were with injectables. During the prescription evaluation, 38.65% of the prescriptions were incomplete due to multiple omissions such as dose, duration, and formulation. CONCLUSION: Most of the parameters in the present study were out of the range of WHO-recommended prescribing indicators. Therefore, effective intervention program, like training, for the promotion of rational drug use practice was recommended to improve the prescribing pattern of drugs and the quality of prescriptions all over the country.

Objective: Psychiatric disorders are chronic in nature which require medications for a long duration. These medications have been associated with many adverse events. Failure to recognize an adverse drug reaction (ADR) exposes the patient to continuing risk of ADR, leading to a significant impact on patient's quality of life. Thus, the present study carried out to identify the pattern of ADRs reported due to psychotropic medication. Methods: This was a cross-sectional study conducted to analyze ADRs reported from the psychiatry department of a tertiary care teaching hospital from October 2021 to March 2022. Findings: A total of 137 ADRs were identified from 102 patients. Majority of the ADRs were reported from antidepressants, with paroxetine being the leading offending drug. The central nervous system was most commonly affected, and dizziness (13.13%) was the most common ADR noted. On causality assessment, 97 ADRs (70.8%) were of "possible" type. Almost half of the patients with ADRs (47.5%) recovered spontaneously. No ADR encountered turned out to be fatal. Conclusion: The present study revealed that the majority of ADRs reported from psychiatry OPD were mild in nature. We reinforce the identification of ADR is crucial in the hospital setting process as it gives an insight into the risk-benefit ratio for rational use of the drug.
RESUMEN
BACKGROUND: The concept of listing essential medicines can lead to improved supply and access, more rational prescribing, and lower costs of drugs. However, these benefits hinge on the prescription of drugs from an Essential Medicines List (EML). Several studies have highlighted the problem of underutilization of EMLs by prescribers. Therefore, as part of prescription research by the Indian Council of Medical Research-Rational Use of Medicines Centres Network, we evaluated the extent of prescription of drugs not listed in the National List of Essential Medicines (NLEM). MATERIALS AND METHODS: Prescriptions of outpatients from participating centers were included after obtaining verbal/written informed consent as approved by the Ethics Committee, and evaluated for prescription of drugs from the NLEM 2015. RESULTS: Analysis of 4838 prescriptions from 13 tertiary health-care institutes revealed that 2677 (55.33%) prescriptions had at least one non-NLEM drug prescribed. In all, 5215 (31.12%) of the total 16,758 drugs prescribed were not in NLEM. Of these, 2722 (16.24%) were single drugs and 2493 (14.88%) were fixed-dose combinations (FDCs). These comprised 700 different drug products - 346 single drugs and 354 FDCs. The average number of non-NLEM drugs prescribed per prescription was 1.08, while the average number of all drugs prescribed was 3.35 per prescription. It was also found that some of the non-NLEM drugs prescribed had the potential to result in increased cost (for example, levocetirizine), increased adverse effects (dextromethorphan), and less effectiveness (losartan) when compared to their NLEM counterparts. Nonavailability of an essential drug (oral hydroxocobalamin) was another important finding of our study. CONCLUSION: This study highlights the extent and pattern of drugs prescribed from outside the NLEM at the tertiary health-care level and the need for training and enhanced awareness among prescribers for greater utilization of the NLEM.

BACKGROUND & OBJECTIVES: Hydroxychloroquine (HCQ), reported to inhibit severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) replication in in vitro studies, has been recommended for prophylaxis of COVID-19 in healthcare workers (HCWs). The objective of this study was to assess short-term adverse events (AEs) of HCQ in HCWs. METHODS: This cross-sectional study among consenting HCWs taking prophylaxis and working in hospitals with COVID-19 patients used online forms to collect details of HCWs, comorbidities, prophylactic drugs used and AEs after the first dose of HCQ. Verification of dose and AEs was done by personal contact. Multivariate logistic regression analysis was done to determine the effect of age, gender and dose of HCQ on AE. RESULTS: Of the 1303 HCWs included, 98.4 per cent (n=1282) took HCQ and 66 per cent (n=861) took 800 mg as first day's dose. Among the 19.9 per cent (n=259) reporting AEs, 1.5 per cent (n=20) took treatment for AE, none were hospitalized and three discontinued HCQ. Gastrointestinal AEs were the most common (172, 13.2%), with less in older [odds ratio (OR) 0.56, 95% confidence interval (CI) 0.35-0.89], with more in females (OR 2.46, 95% CI 1.78-3.38) and in those taking a total dose of 800 mg on day one compared to a lower dose. Hypoglycaemia (1.1%, n=14), cardiovascular events (0.7%, n=9) and other AEs were minimal. INTERPRETATION & CONCLUSIONS: HCQ prophylaxis first dose was well tolerated among HCWs as evidenced by a low discontinuation. For adverse effects, a small number required treatment, and none required hospitalization. The study had limitations of convenience sampling and lack of laboratory and electrocardiography confirmation of AEs.

BACKGROUND: It is critical for medical students to retain and apply their knowledge of basic sciences to become competent prescribing physicians. Poor long-term retention is a pervasive concern. We investigated the impact of 'spaced education' teaching modules to improve knowledge retention in medical students on a topic of public health: vitamin D and its role in health and disease. It is critical for medical students to retain and apply their knowledge of basic sciences to become competent prescribing physicians METHODS: In a self-matched design, 148 medical students were randomised and evaluated on vitamin D-related topics to assess reinforced and non-reinforced knowledge in a multiple-choice question format. Initial learning and long-term retention were assessed with an estimation of Cohen's effect size at 24 and 72 weeks, respectively. RESULTS: The administration of spaced educational material significantly improved composite formative test scores at 24 weeks (p < 0.001, effect size = 1.33). Although the scores dipped, there was a retention of knowledge at 72 weeks (effect size = 0.48). DISCUSSION: Spaced reinforcement and testing statistically improved knowledge retention among our medical students. Gaps in the present teaching could be bridged by motivating the students to extend their learning time by appropriate spacing intervals and to understand the relevance of course content in different scenarios as a physician. Further research could be instrumental in optimising interventions to enhance learning opportunities for medical students.

RESUMEN
Arterial/venous thrombosis is the major cardiovascular disorder accountable for substantial mortality; and the current demand for antithrombotic agents is extensive. Heparinases depolymerize unfractionated heparin (UFH) for the production of low molecular-weight heparins (LMWHs; used as anticoagulants against thrombosis). A microbial strain of Streptomyces sp. showing antithrombotic activity was isolated from the soil sample collected from north India. The strain was characterized by using 16S rRNA homology technique and identified as Streptomyces variabilis MTCC 12266 capable of producing heparinase enzyme. This is the very first communication reporting Streptomyces genus as the producer of heparinase. It was observed that the production of intracellular heparinase was [63.8 U/mg protein (specific activity)] 1.58 folds higher compared to extracellular heparinase [40.28 U/mg protein]. DEAE-Sephadex A-50 column followed by Sepharose-6B column purification of the crude protein resulted 19.18 folds purified heparinase. SDS-PAGE analysis of heparinase resulted an estimated molecular-weight of 42 kDa. It was also found that intracellular heparinase has the ability to depolymerize heparin to generate LMWHs. Further studies related to the mechanistic action, structural details, and genomics involved in heparinase production from Streptomyces variabilis are warranted for large scale production/purification optimization of heparinase for antithrombotic applications.

Printing of electronic devices on a paper substrate using 2D graphene-based ink is an opening gate to innovative applications, where devices would be biodegradable, eco-friendly and can be disposed of with negligible impact on the environment. A resistor is a key element of electronic devices and their application area depends upon its power rating and temperature coefficient of resistance (TCR). In this work, in house developed graphene ink is successfully utilized to fabricate a paper-based resistor using a bar coating technique. Dimensional patterning with precise known values of resistance is achieved using a laser with freedom of shape and size which has been explored for the first time on a paper substrate. The resistor has potential to handle â¼7 W power at room temperature with capacity to withstand up to 200 V which is the highest among reported printed resistors. A dual, low and high TCR is observed, correspondingly in cold (173 K to 300 K) and hot (300 K to 373 K) temperature regions with an activation energy E a of â¼8 meV for the cold region which is 375 percent lower than the hot region (â¼30 meV). The dual TCR behaviour is of great importance for application as a stable resistor up to room temperature, and as a thermistor above room temperature.
RESUMEN
During the screening programme for microbial cultures producing antimicrobial agents, an active microbial strain of Streptomyces was isolated from the agricultural soil of Narnaul, Haryana India. Physiological, biochemical characteristics and 16S ribosomal RNA sequence homology studies revealed that it was similar to Streptomyces levis (sequence similarity 100%). The microbial strain was submitted to Genomebio Technologies Pvt. Ltd., Pune, Maharashtra, India under Accession No. EU124569. The isolated strain was found to produce extracellular active compound showing strong antimicrobial activity against Klebsiella pneumoniae MTCC 109, Pseudomonas aeruginosa MTCC 741 and Staphylococcus aureus MTCC 96. The antibacterial compound was successfully isolated and purified. Structure elucidation of antibacterial metabolite with EI-MS/ HRMS showed molecular ion peak at m/z 686 [M+H]+. Whereas, elemental analysis of the said compound showed C = 61.31, H = 8.61, N = 2.04 and O = 28.02, and indicated a molecular formula of C35H59NO12. The presence of 'chromone' nucleus in the compound's chemical structure was confirmed by using 1HNMR studies. The present study reports the purification of potential antibacterial compound from Streptomyces levis isolated from the unexplored soil of north India and warrants for further characterization of this potential compound for optimum utilization for antimicrobial purposes.

The applicability of the statistical tools coupled with artificial intelligence techniques was tested to optimize the critical medium components for the production of extracellular cholesterol oxidase (COD; an enzyme of commercial interest) from Streptomyces rimosus MTCC 10792. The initial medium component screening was performed using Placket-Burman design with yeast extract, dextrose, starch and ammonium carbonate as significant factors. Response surface methodology (RSM) was attempted to develop a statistical model with a significant coefficient of determination (R2 = 0.89847), followed by model optimization using Genetic Algorithm (GA). RSM-GA based optimization approach predicted that the combination of yeast extract, dextrose, starch and ammonium carbonate at concentrations 0.99, 0.8, 0.1, and 0.05 g/100 ml respectively, has resulted in 3.6 folds increase in COD production (5.41 U/ml) in comparison with the un-optimized medium (1.5 U/ml). COD was purified 10.34 folds having specific activity of 12.37 U/mg with molecular mass of 54 kDa. The enzyme was stable at pH 7.0 and 40 °C temperature. The apparent Michaelis constant (Km) and Vmax values of COD were 0.043 mM and 2.21 µmol/min/mg, respectively. This is the first communication reporting RSM-GA based medium optimization, purification and characterization of COD by S. rimosus isolated from the forest soil of eastern India.

BACKGROUND: Stevens-Johnson syndrome (SJS) and toxic epidermal necrolysis (TEN) are life-threatening hypersensitivity reactions mainly caused by drugs. Data on incubation period, hospital stay, and outcome for HIV-positive patients are sparse. Role of corticosteroids in their management is still controversial. METHODS: Indoor cases of SJS, SJS-TEN overlap, and TEN were analyzed for causative drugs, incubation period, a severity-of-illness score for toxic epidermal necrolysis (SCORTEN) score, HIV status, treatment, and outcome. Comparison of parameters between HIV and non-HIV cases was done. Utilization pattern of corticosteroids and their role in outcome were evaluated. RESULTS: Four SJS, 15 SJS-TEN overlap, and 21 TEN cases were evaluated. Antimicrobials (27.1%), antiviral (23%), antiseizure drugs (8.4%), and analgesics (8.4%) were commonly associated drugs. Among 12 (30%) HIV-reactive cases, nevirapine (97.6%) and cotrimoxazole (41.6%) were common causative drugs. Males (75%) were affected more than females (25%) among HIV-positive individuals. Incubation period was significantly higher in HIV-reactive patients. Total 30 (75%) patients were treated with corticosteroids. Dexamethasone (90%) and prednisolone (26.6%) were most commonly used. No significant difference was found among cases treated with or without corticosteroids. CONCLUSIONS: Antimicrobial drugs are common to cause SJS/TEN. Among HIV-reactive patients, male have more risk, incubation period is more and severity of reaction is less. Effectiveness of corticosteroids for treatment of SJS/TEN is inconclusive.

Molecular hybridization approach is an emerging tool in drug discovery for designing new pharmacophores with biological activity. A novel, new series of coumarin-benzimidazole hybrids were designed, synthesized and evaluated for their broad spectrum antimicrobial activity. Among all the synthesized molecules, compound (E)-3-(2-1H-benzo[d]imidazol-1-yl)-1-((4-chlorobenzyl)oxy)imino)ethyl)-2H-chromen-2-one showed the most promising broad spectrum antibacterial activity against Pseudomonas aeruginosa, Staphylococcus aureus, Bacillus subtilis and Proteus vulgaris. In addition, it has showed no cytotoxicity and hemolysis at 10 times the MIC concentration. SAR studies indicate that position of the chlorine atom in the hybrid critically determines the antibacterial activity.

Vitamin D deficiency is prevalent across all age groups in epidemic proportions. The purpose of this study was to acquire a baseline assessment and create awareness among medical students regarding vitamin D. A cross-sectional, voluntary survey was conducted among undergraduate medical students. Data were collected using a questionnaire which assessed the level of knowledge students had with regard to where vitamin D comes from, what it does for health, how much is recommended, factors that affect its levels, and deficiency management. Majority of students were unaware that vitamin D deficiency has attained epidemic proportions. Though bone and skeletal disorders as a complication of vitamin D deficiency were known, a large number were unaware of systemic consequences (diabetes mellitus, cardiovascular diseases, and cancers). Only one-third of respondents were aware of duration and timing of sun exposure required for adequate serum vitamin D levels. However, we observed lack of awareness among students regarding the various biochemical forms, dose, and duration of vitamin D supplementation for treatment of nutritional deficiency. Our study highlighted a lack of knowledge about the importance of vitamin D, worldwide prevalence of vitamin D deficiency, and its management among medical students. Promoting vitamin D health awareness, if replicated across populations, could lead to positive health outcomes globally.

BACKGROUND: Caregiver burden in dementia is an important area of research. Providing care for a relative can be a potent source of chronic stress and can have deleterious consequences for both the physical and emotional health of caregivers. This study aims to evaluate the burden of care in caregivers of patients with Alzheimer-type dementia and compare it with elderly psychosis; and to also study the factors that influence burden of care in Alzheimer's dementia. METHODS: Thirty-two caregiver-patient dyads of Alzheimer-type dementia were compared with thirty-two caregiver-patient dyads of psychosis. Cognitive assessment, abilities to perform activities of daily living and severity of dementia was assessed in the patients. Zarit Burden Interview was used to study the caregiver burden in both groups. RESULTS: The mean burden score in dementia caregivers was high at 47.7, whereas the mean burden score for elderly psychosis caregivers was lesser at 33.6, and this difference in mean burden scores was found to be statistically significant. Spouses had the highest mean burden scores of 53.48. Caregiver burden in dementia was positively correlated with cognitive impairment and inability to carry out ADLs. Presence of psychological distress in caregivers was also an indicator for greater caregiver burden in dementia. CONCLUSION: The study revealed that dementia carries a greater caregiver burden when compared with elderly patients with psychosis. Innovative interventions are needed to remove burden from caregiving, making it a meaningful practice integral to the Indian society.
