RESUMO

There is evidence, obtained both with animal model systems and with humans, that intermittent fasting (time restricted eating) has health benefits. These benefits include extended longevity, weight loss and counteracting various disease conditions. Such procedures influence human tissue-specific microbiomes and organellar apoptosis. In this review, we shall attempt to summarize the predominant evidence published in the scientific literature relevant to these conclusions.

RESUMO

BACKGROUND: Dehydration is a highly prevalent clinical challenge in adults which can go undetected. Although dehydration is commonly associated with an increased risk of hospitalization and mortality, only a few international guidelines provide recommendations regarding oral fluids, electrolytes, and energy (FEE) management in adults/geriatrics with dehydration due to nondiarrheal causes. Currently, there is a lack of comprehensive recommendations on the role of oral FEE in nondiarrheal dehydration in adult and geriatric Indian patients. MATERIALS AND METHODS: A modified Delphi approach was designed using an online questionnaire-based survey followed by a virtual meeting, and another round of online surveys was used to develop this consensus recommendation. In round one, 130 statements, including 21 open-ended questions, were circulated among ten national experts who were asked to either strongly agree, agree, disagree, or strongly disagree with statements and provide responses to open-ended questions. The consensus was predefined at 75% agreement (pooling "strongly agree" and "agree" responses). Presentation of relevant literature was done during a virtual discussion, and some statements (the ones that did not achieve predefined agreement) were actively discussed and deliberately debated to arrive at conclusive statements. Those statements that did not reach consensus were revised and recirculated during round two. RESULTS: Consensus was achieved for 130/130 statements covering various domains such as assessment of dehydration, dehydration in geriatrics, energy requirement, impact of oral FEE on patient outcome, and fluid recommendations in acute and chronic nondiarrheal illness. However, one statement was not added as a recommendation in the final consensus (129/130) as further literature review did not find any supporting data. Oral FEE should be recommended as part of core treatment from day 1 of acute nondiarrheal illness and started at the earliest feasibility in chronic illnesses for improved patient outcomes. Appropriately formulated fluids with known electrolyte and energy content, quality standards, and improved palatability may further impact patient compliance and could be a good option. CONCLUSION: These consensus recommendations provide guidance for oral FEE recommendations in Indian adult/geriatric patients with various nondiarrheal illnesses.

RESUMO

BACKGROUND: Dehydration due to reduced intake or increased losses including insensible losses in patients with acute nondiarrheal diseases may lead to fluid, electrolytes, and energy (FEE) deficits. The impact of oral FEE supplementation adjuvant to standard of care (SOC) treatment on recovery in patients with acute nondiarrheal diseases is yet to be evaluated. AIM: To determine the effectiveness of ORSL® variants (ORSL® Apple Drink and ORSL® PLUS Orange Drink), fruit juice-based electrolyte drinks as an adjuvant along with SOC in the restoration of oral FEE in patients with acute nondiarrheal disease with fever and/or general weakness who attended an outpatient department (OPD). MATERIALS AND METHODS: This was a prospective, interventional, open-label, multicenter, real-world, study conducted at eight sites across India. Patients with fever and/or general weakness due to an acute nondiarrheal illness were given either ORSL® Apple Drink or ORSL® PLUS Orange Drink as an adjuvant along with SOC treatment per physician's discretion. The primary endpoint of the study was to assess improvement from baseline in energy or hydration levels after ORSL® variants consumption at 6, 24, and 48 hours measured by a new aided recovery scale (ARS). Secondary endpoints were to assess the improvement in energy and hydration levels at 20, 40, and 60 minutes, as well as energy levels and hydration levels at 20, 40, and 60 minutes, 6, 24, and 48 hours after the consumption of ORSL® Apple Drink or ORSL® PLUS Orange Drink. The patient's consumption of ORSL® variants and treatment experience, physician's experience of recommending ORSL® variants, and product safety were evaluated. RESULTS: In total, 612 patients were enrolled with mean age 38.3 years, of whom 62.9% were male. The mean baseline level of energy and hydration was 1.59 (range 1.0-2.0) on ARS. Statistically significant (p < 0.0001) improvements were observed in energy or hydration 6 hours after first consumption of ORSL formulations. Furthermore, improvement was observed from 40 minutes, and in levels of energy, hydration, and both energy and hydration from 60 minutes. Patients and physicians reported a positive experience with ORSL® variants. CONCLUSION: ORSL® Apple Drink and ORSL® PLUS Orange Drink are clinically proven to provide hydration and/or energy to patients with fever and/or general weakness.

RESUMO

Acute nondiarrheal illnesses (NDIs) involve overt or subclinical dehydration, requiring rehydration and electrolyte repletion. Dehydration is frequently under-recognized and under-managed, both in outpatient departments (OPDs) and inpatient departments (IPDs). Postadmission dehydration is associated with longer hospital stays and higher inhospital mortality rates. Recognizing and understanding dehydration in hospitalized patients is necessary due to the adverse outcomes associated with this condition. In this article, we aimed to develop practical consensus recommendations on the role of oral fluid, electrolyte, and energy (FEE) management in hospitalized patients with FEE deficits in NDI. The modified Delphi consensus methodology was utilized to reach a consensus. A scientific committee comprising eight experts from India formed the panel. Relevant clinical questions within three major domains were formulated for presentation and discussion: (1) burden and factors contributing to dehydration in hospitalized patients; (2) assessment of fluid and electrolyte losses and increased energy requirements in hospitalized patients; and (3) management of FEE deficits in hospitalized patients [at admission, during intravenous (IV) therapy, IV to oral de-escalation, and discharge]. The consensus level was classified into agreement (mean score ≥4), no consensus (mean score <4), and exclusion (mean score <4 after the third round of discussion). The questions that lacked agreement were discussed during the virtual meeting. The experts agreed that the most common factors contributing to dehydration in patients with NDI hospitalized in IPDs include decreased oral fluid intake, increased fluid loss due to the illness, insensible fluid loss, and a lack of awareness among doctors about dehydration, which can result in poor fluid intake. Time constraints, discontinuity of care, lack of awareness of the principles of fluid balance, lack of formal procedures for enforcing hydration schemes, and lack of adequate training are most often barriers to the assessment of hydration status in hospital settings. Experts used hydration biomarkers, such as changes in body weight, serum, or plasma osmolality; fluid intake; and fluid balance charts; along with urine output, frequency, quantity, and color, to determine hydration status in hospital settings. Experts agreed that appropriate FEE supplementation in the form of ready-to-drink (RTD) fluids can restore FEE deficits and shorten the length of hospital stays in hospitalized patients at admission, during de-escalation from IV to oral therapy, and at discharge. RTD electrolyte solutions with known concentrations of electrolytes and energy are good choices to avoid taste fatigue and replenish FEE in hospitalized patients during transition care and at discharge.

RESUMO

This article represents a novel study of the design and analysis of a wind turbine system that includes a line-side permanent magnet synchronous generator (PMSG) with an ultra-step-up DC-DC converter for voltage regulation. Integrating renewable energy sources such as wind power into the grid requires efficient and reliable power conversion systems to handle fluctuating power and ensure a stable power supply. The wind turbine system utilizes a PMSG, which offers several advantages over traditional induction generators, including higher efficiency, reduced maintenance, and better power quality. The line-side configuration allows for increased control and flexibility, allowing the system to respond dynamically to grid conditions. This wind turbine system involves the integration of a grid-side PMSG-fed DC-DC converter between the PMSG and the grid. The converter enables a seamless flow of electricity between the wind turbine and the grid. By actively controlling the intermediate circuit voltage, the converter efficiently regulates the output voltage of the wind turbine and thus enables constant power generation regardless of fluctuating wind speeds. The simulation outcomes illustrate the efficacy of the proposed system in achieving voltage regulation and seamless integration with the grid. Performance is evaluated under various operating conditions and compared to conventional wind turbines.

RESUMO

The development of DC microgrids is reliant on multi-input converters, which offer several advantages, including enhanced DC power generation and consumption efficiency, simplified quality, and stability. This paper describes the development of a multiple input supply based modified SEPIC DC-DC Converter for efficient management of DC microgrid that is powered by two DC sources. Here Multi-Input SEPIC converter offers both versatility in handling output voltage ranges and efficiency in power flow, even under challenging operating conditions like lower duty cycle values. These features contribute to the converter's effectiveness in managing power within a DC microgrid. In this configuration, the DC sources can supply energy to the load together or separately, depending on how the power switches operate. The detailed working states with equivalent circuit diagrams and theoretical waveforms, under steady-state conditions, are shown along with the current direction equations. This paper also demonstrates the typical analysis of large-signal, small-signal, steady-state modeling techniques and detailed design equations. The proposed configuration is validated through the conceptual examination using theoretical and comprehensive MATLAB simulation results. Detailed performance analysis has been done for different cases with various duty ratios. Finally, to show the competitiveness, the multi-input SEPIC topology is compared with similar recent converters.

RESUMO

Background and Objective: Dental erosion is a condition that results from exposure of the enamel and dentin to non-bacterial acids of extrinsic and intrinsic origin, causing mineral loss on the surface of the tooth. Occupational exposure to sulfuric acid fumes has been described in association with dental erosion in battery manufacturing industry workers. Hence, this study aimed to assess the dental erosion among battery factory workers in HBL Power Systems Ltd, Hyderabad. Materials and Methods: The sample consisted of 90 battery factory workers (62 males and 28 females). Demographic data with regard to age, gender, and length of exposure were recorded. Clinical examination was done to assess dental erosion using the tooth wear index given by Smith and Knight. Data were statistically analyzed by using Fisher exact test. P <0.05 was considered statistically significant. Results: Among 90 workers examined, 43.3% showed prevalence of erosion with higher occurrence rate in females (54%) than males (38.7%). 66.6% of affected workers had erosion score of 1, and 33.4% showed erosion score of 2 and 3. We also observed statistically significant highest prevalence and increased severity of dental erosion in workers with prolonged duration of employment (>11 years). Conclusion: The present study revealed increased prevalence of dental erosion among battery factory workers. Hence, it highlights the importance of protective measures with efficient surveillance and monitoring in the workplace environment.

RESUMO

Fusarium wilt, caused by (Fusarium udum Butler), is a significant threat to pigeonpea crops worldwide, leading to substantial yield losses. Traditional approaches like fungicides and resistant cultivars are not practical due to the persistent and evolving nature of the pathogen. Therefore, native biocontrol agents are considered to be more sustainable solution, as they adapt well to local soil and climatic conditions. In this study, five isolates of F. udum infecting pigeonpea were isolated from various cultivars and characterized morphologically and molecularly. The isolate from the ICP 8858 cultivar displayed the highest virulence of 90%. Besides, 100 endophytic bacteria, 100 rhizosphere bacteria and three Trichoderma spp. were isolated and tested against F. udum isolated from ICP 8858 under in vitro conditions. Out of the 200 bacteria tested, nine showed highest inhibition, including Rb-4 (Bacillus sp.), Rb-11 (B. subtilis), Rb-14 (B. megaterium), Rb-18 (B. subtilis), Rb-19 (B. velezensis), Eb-8 (Bacillus sp.), Eb-11 (B. subtilis), Eb-13 (P. aeruginosa), and Eb-21 (P. aeruginosa). Similarly, Trichoderma spp. were identified as T. harzianum, T. asperellum and Trichoderma sp. Notably, Rb-18 (B. subtilis) and Eb-21 (P. aeruginosa) exhibited promising characteristics such as the production of hydrogen cyanide (HCN), cellulase, siderophores, ammonia and nutrient solubilization. Furthermore, treating pigeonpea seedlings with these beneficial microorganisms led to increased levels of key enzymes (POD, PPO, and PAL) associated with resistance to Fusarium wilt, compared to untreated controls. In field trials conducted for four seasons, the application of these potential biocontrol agents as seed treatments on the susceptible ICP2376 cultivar led to the lowest disease incidence. Specifically, treatments T2 (33.33) (P. aeruginosa) and T3 (35.41) (T. harzianium) exhibited the lowest disease incidence, followed by T6 (36.5) (Carbendizim), T1 (36.66) (B. subtilis), T4 (52.91) (T. asperellum) and T5 (53.33) (Trichoderma sp.). Results of this study revealed that, P. aeruginosa (Eb-21), B. subtilis (Rb-18) and T. harzianum can be used for plant growth promotion and management of Fusarium wilt of pigeonpea.

RESUMO

Fusarium wilt (FW) is the most severe soil-borne disease of chickpea that causes yield losses up to 100%. To improve FW resistance in JG 11, a high-yielding variety that became susceptible to FW, we used WR 315 as the donor parent and followed the pedigree breeding method. Based on disease resistance and yield performance, four lines were evaluated in station trials during 2017-2018 and 2018-2019 at Kalaburagi, India. Further, two lines, namely, Kalaburagi chickpea desi 5 (KCD 5) and KCD 11, which possesses the resistance allele for a specific single-nucleotide polymorphism marker linked with FW resistance, were evaluated across six different locations (Bidar, Kalaburagi, Raichur, Siruguppa, Bhimarayanagudi and Hagari) over a span of 3 years (2020-2021, 2021-2022 and 2022-2023). KCD 11 exhibited notable performance, showcasing yield advantages of 8.67%, 11.26% and 23.88% over JG 11, and the regional checks Super Annigeri 1 (SA 1) and Annigeri 1, respectively, with enhanced FW resistance in wilt sick plot. Further, KCD 11 outperformed JG 11, SA 1 and Annigeri 1 in multi-location trials conducted across three seasons in the North Eastern Transition Zone, North Eastern Dry Zone, and North Dry Zones of Karnataka. KCD 11 was also tested in trials conducted by All India Coordinated Research Project on chickpea and was also nominated for state varietal trials for its release as a FW-resistant and high-yielding variety. The selected line is anticipated to cater the needs of chickpea growers with the dual advantage of yield increment and disease resistance.

RESUMO

A finite difference numerical simulation scrutiny is executed to evaluate the combined impacts of heat generation, buoyancy forces, viscous dissipation and Joule heating in unsteady hydro-magnetic mixed convective chemically reactive and radiative Casson fluid flowing along an exponentially accelerating permeable vertical plate engrossed in a porous media by considering ramp surface concentration and temperature. The dimensionless non-linear coupled PDEs describing the flow model are dealt numerically by adopting the competent implicit Crank-Nicolson finite difference procedure. The variance of velocity, temperature, and concentration distributions are exposed via graphical representations due to the dissimilarity of the flow restrained parameters. Computational outcomes of the skin-friction, Nusselt and the Sherwood numbers are portrayed in the tabular pattern. The final outcomes of the research exposed that the impacts of thermal radiation, viscous dissipation, and heat production parameters enlarges the temperature and velocity distributions. The fluid motion deflates for growing Casson parameter and magnetic field intensity. The rising chemical reaction parameter suppresses the concentration and velocity distributions. Very importantly it is distinguished that fluid momentum, temperature, and concentration are quicker in the instance of isothermal plate temperature than ramp wall temperature. This kind of research may find specific industrial and medical utilizations such as glass manufacturing, crude oil purification, lubrication, paper production, blood transport study in cardiovascular design, etc.

RESUMO

Proxy procedures in psychiatry include proxy consultations, proxy prescriptions, covert and refill medications. Before Mental Healthcare Act (MHCA) 2017, there was minimal emphasis on the rights of individuals with Severe Mental Illness (SMI), leading family members to use proxy practices. With the new legislation, these practices have to be seen in a new light. Proxy consultations may be allowed for information, advice, etc. but not for giving medications or making a diagnosis. Proxy prescriptions can be given if the patient gives prior authorization or through nominated representative in advanced directive. Psychiatrists may consider covert medications if the patient lacks capacity, but not in emergencies. Medication refills can be given with physicians' recommendation for a specific duration.

RESUMO

Background: Micronutrients are necessary for proper growth and development of the human body, though required in small amounts. Dietary intake of these micronutrients by lactating women is essential for their own health as well as children's overall growth and development. objective of present study is to assess the adequacy of dietary B-group vitamins intake during lactation and to find out the factors associated with their inadequate intake. Design and methods: It was a analysis of data from prospective cohort study for 10 months carried out among 340 Scheduled Tribes mothers in 10 clusters in Guntur district, Andhra Pradesh, India. Data collection was done using a 24 h dietary recall questionnaire. A p-value less than 0.05 was considered to be statistically significant. Results: All the mothers (n = 340) were not having adequate intake of Thiamine, Riboflavin, Niacin, Pyridoxine, Pantothenic acid, Biotin and Folic acid. Methyl cobalamin intake was inadequate in 37.5% mothers (n = 136). The mean intake of Vitamin B12 was 40.98 + 42.8 (SD) µg/day. Age at marriage, location and parity were significantly associated with inadequate intake of Vitamin B12. Conclusions: The current diet pattern of mothers of vulnerable groups might affect the growth and development of the infant. We strongly recommend for supplementation of B-group vitamins to pregnant and lactating women in India.

RESUMO

The success of the mRNA vaccine against COVID-19 has garnered significant interest in the development of mRNA therapeutics against other diseases, but there remains a strong need for a stable and versatile delivery platform for these therapeutics. In this study, we report on a family of robust hybrid lipid nanocapsules (hLNCs) for the delivery of mRNA. The hLNCs are composed of kolliphore HS15, labrafac lipophile WL1349, 1,2-dioleoyl-sn-glycero-3-phosphoethanolamine (DOPE), and a conjugate of oleic acid (OA) and polyethylenimines of varying size (PEI─0.8, 1.8, and 25 kDa). They are prepared by a solvent-free, temperature-phase inversion method, yielding an average size of ∼40 nm and a particle distribution index (PDI) < 0.2. We demonstrate that the PDI remains <0.2 over a wide pH range and in a wide range of medium. We further show that the PDI and the functionality of mRNA condensed on the particles are robust to drying in a sugar glass and subsequent rehydration. Finally, we demonstrate that mRNA-loaded hLNCs yield reasonable transfection in vitro and in vivo settings.

RESUMO

The present work represents a novel methodology for the selective arylation of coumarin-3-carboxylates with arylboronic acids via a photochemical route, marking the first-ever attempt for the direct alkenyl C-H arylation using rose bengal as a photocatalyst, which is a readily available and cost-effective alternative to transition metal catalysis. The reaction proceeds smoothly in MeOH/H2O solvent media in the presence of radical initiator affording the arylated products in good yields (60-80 %). The reaction parameters such as visible light, radical initiator, oxidant, anhydrous solvent, and inert atmosphere play a crucial role for the success of this methodology. The substituents present on the substrate show a significant effect on the conversion. This study provides a valuable contribution to the field of organic synthesis offering a new and efficient approach to the arylation of coumarin-3-carboxylic acid esters with a broad substrate scope and high functional group tolerance. It is a versatile method and provides a direct access to biologically relevant 4-arylcoumarin-3-carboxylates.

RESUMO

The finite element simulations of the Soret-Dufour and angled magnetic field effects on conjugate heat and mass transportation of unsteady heat absorbing hydromagnetic Casson flow across a semi-infinite flat oscillatory plate engrafted in a porous medium with suction/blowing, radiation and chemical reaction is performed. The dimensionless coupled flow guiding nonlinear PDEs of the physical structure is handled numerically by the dynamic Galerkin finite element scheme. The demeanor of the velocity, concentration and the temperature profiles due to the alterations in the regulating flow parameters are examined graphically whereas the wall-friction, mass and heat transfer rates explicated by utilizing the tabular data. The research discovered that radiation; conjugate heat transfer and diffusion thermo effects heighten the temperature and velocity distributions whereas heat absorption has a reverse effect. Likewise, conjugate mass transfer and thermo-diffusion effects intensify the concentration and velocity distributions whereas the chemical reaction display overturns aspect. Increased radiation absorption, inclined magnetic field and porosity parameter stimulate fluid velocity whereas the Casson and magnetic parameters exhibit the converse impact. In the instance of suction, the profiles of concentration, velocity and temperature displayed a downturn nature but for the case of blowing, it was noticed a reversal trend. Further, a comparative analysis between the current findings and existing research works in the literature demonstrates our results are exact and accurate.

RESUMO

Short Title: Benzimidazoisoquinoline derivatives as potent antifibrotics Hepatic fibrosis is a pathological condition of liver disease with an increasing number of cases worldwide. Therapeutic strategies are warranted to target the activated hepatic stellate cells (HSCs), the collagen-producing cells, an effective strategy for controlling the disease progression. Benzimidazoisoquinoline derivatives were synthesized as hybrid molecules by the combination of benzimidazoles and isoquinolines to evaluate their anti-fibrotic potential using an in-vitro and in-vivo model of hepatic fibrosis. A small library of benzimidazoisoquinoline derivatives (1-17 and 18-21) was synthesized from 2-aryl benzimidazole and acetylene functionalities through C-H and N-H activation. Compounds (10 and its recently synthesized derivatives 18-21) depicted a significant decrease in PDGF-BB and/or TGFß-induced proliferation (1.7-1.9 -fold), migration (3.5-5.0 -fold), and fibrosis-related gene expressions in HSCs. These compounds could revert the hepatic damage caused by chronic exposure to hepatotoxicants, ethanol, and/or carbon tetrachloride as evident from the histological, biochemical, and molecular analysis. Anti-fibrotic effect of the compounds was supported by the decrease in the malondialdehyde level, collagen deposition, and gene expression levels of fibrosis-related markers such as α-SMA, COL1α1, PDGFRß, and TGFRIIß in the preclinical models of hepatic fibrosis. In conclusion, the synthesized benzimidazoisoquinoline derivatives (compounds 18, 19, 20, and 21) possess anti-fibrotic therapeutic potential against liver fibrosis.

RESUMO

A highly stereoselective total synthesis of polyrhacitide A, a polyketide natural product, has been accomplished by means of Prins cyclisation. The key precursor i.e. anti-1,3-diol for polyrhacitide A has been prepared from trans-2,6-disubstituted-3,4-dihydropyrans. In this approach, Prins cyclisation has successfully been utilised twice for the construction of 1,3-diol unit of polyrhacitide A. The key steps involved in this approach are Jacobsen hydrolytic kinetic resolution, Mitsunobu inversion, Prins cyclisation and Ring-closing metathesis (RCM).

RESUMO

Background In Andhra Pradesh, India, tribal communities face unique nutritional challenges due to limited access to healthcare and a predominantly plant-based diet. Maternal undernutrition is a significant concern, impacting the well-being of both mothers and their offspring. This study focuses on assessing the prevalence of undernutrition among tribal mothers in Andhra Pradesh using the BMI-for-age criterion. Objectives The aim of this study was to comprehensively evaluate the prevalence of undernutrition among tribal mothers, explore associations with demographic factors, and assess the impact of a nutritional intervention program. The ultimate goal was to contribute to targeted interventions and policies for improving the health and well-being of these communities. Materials and methods A cohort study was conducted in the Guntur district of Andhra Pradesh, involving 340 lactating mothers and their infants. Data collection and anthropometric measurements were performed. Results The study found that 67 (19.71%) of tribal mothers were underweight at baseline. There were statistically significant associations with the Yenadi tribe, low educational status of the mother, and history of lower segment Caesarean section with a high prevalence of being underweight. No significant associations with age, occupation, or socioeconomic status were observed. Undernutrition was more common among mothers with older children and was associated with specific obstetric factors. Conclusion While the prevalence of undernutrition is lower than in some previous studies, it remains a critical concern, particularly within disadvantaged communities. These undernourished mothers face health risks, including anemia. Urgent policy interventions and nutritional programs are needed to address this issue and enhance the well-being of tribal communities in Andhra Pradesh.

RESUMO

Meat is a rich source of high biological proteins, vitamins, and minerals, but it is devoid of dietary fiber, an essential non-digestible carbohydrate component such as cellulose, hemicellulose, pectin, lignin, polysaccharides, and oligosaccharides. Dietary fibers are basically obtained from various cereals, legumes, fruits, vegetables, and their by-products and have numerous nutritional, functional, and health-benefiting properties. So, these fibers can be added to meat products to enhance their physicochemical properties, chemical composition, textural properties, and organoleptic qualities, as well as biological activities in controlling various lifestyle ailments such as obesity, certain cancers, type-II diabetes, cardiovascular diseases, and bowel disorders. These dietary fibers can also be used in meat products as an efficient extender/binder/filler to reduce the cost of production by increasing the cooking yield as well as by reducing the lean meat content and also as a fat replacer to minimize unhealthy fat content in the developed meat products. So, growing interest has been observed among meat processors, researchers, and scientists in exploring various new sources of dietary fibers for developing dietary fiber-enriched meat products in recent years. In the present review, various novel sources of dietary fibers, their physiological effects, their use in meat products, and their impact on various physicochemical, functional, and sensory attributes have been focused.

RESUMO

Menstrual hygiene management, especially in resource-limited settings, is challenging. The acceptability of the menstrual cup is increasing recently in western countries whereas, in developing countries like India, the awareness, acceptability, and use of menstrual cups are very limited. We assessed the effectiveness of modified pre-post-test teaching-learning methodology in an online webinar series on menstrual cups using Moore's outcome assessment. An online webinar series on menstrual hygiene and the menstrual cup was conducted to raise awareness about the usage of menstrual cups among the health care workers like Auxiliary Nurse Midwife (ANMs), Accredited Social Health Activist (ASHAs), and Anganwadi Workers (AWWs) of the Guntur district, Andhra Pradesh, India. The questions of modified pre- and post-test were displayed. The questions were displayed to participants using the polling option in zoom. A total of 1597 health care workers participated in the menstrual cup webinar series. Of the total, 72.7% of participants responded to the job title question of which ASHA, ANMs, and AWWs were 16.8%, 34.2%, and 41.9%, respectively. The baseline knowledge of menstrual cups among primary health care workers for "heard of the menstrual cup" and "ever used/know anyone using menstrual cup" was 36.89% and 11.67%, respectively. After the webinar among the primary health care workers, the maximum gain in knowledge was seen for "menstrual cup can be cleaned in the home," 94.53%, and the minimum gain in knowledge was on "unmarried girls can use menstrual cups," 50.42%. The modified pre- and post-test model predicted an overall 50 percent rise in the knowledge of primary health care workers by the webinar series about a different aspect of the menstrual cup.As online webinar providers aim to provide more performance-based learning activities, current approaches to continuing medical education may become obsolete. The single most essential shift in online webinar planners can make is to incorporate modified pre-and post-test to allow for interactive and formative assessment during webinar activities.
