RESUMEN
The enantioselective 1,4-addition reaction of pyrazolin-5-ones to α,ß-unsaturated ketones catalyzed by a cinchona alkaloid-derived primary amine-Brønsted acid composite is reported. Both enantiomers of the anticipated pyrazole derivatives were obtained in good to excellent yields (up to 97%) and high enantioselectivities (up to 98.5% ee) under mild reaction conditions. In addition, this protocol was further expanded to synthesize highly enantioenriched hybrid molecules bearing biologically relevant heterocycles.
RESUMEN
BACKGROUND: Assessing patients' satisfaction is an easy and cost-effective method of evaluating the outpatient services provided by health-care institutions. OBJECTIVES: The objectives of this study were to determine patient satisfaction among patients attending various outpatient departments (OPDs) at a tertiary care hospital and the factors affecting their satisfaction. MATERIALS AND METHODS: A cross-sectional study was conducted among patients attending various OPDs at a tertiary care hospital in Faridabad. Exit face-to-face interviews were conducted for 334 patients above 18 years of age who availed OPD services followed by pharmacy services. Information regarding sociodemography, rating of satisfaction with various attributes of OPD services on a 5-point Likert scale, and reasons for dissatisfaction was collected. Data were analyzed using SPSS version 22. Root cause analysis for the lowest-scoring attribute was done using fishbone diagram. RESULTS: About 64% of the patients were satisfied with the OPD services. "Attitude and communication of doctors" was the prime contributor to patient satisfaction. "Promptness at medicine distribution counter" was the attribute that scored lowest followed by "waiting time at the registration counter." The mean waiting time for registration was 38.2 min, for consultation with doctor 41.3 min, for collection of samples 49.6 min, and for drug dispensing 61 min. CONCLUSION: The issues related to pharmacy services need to be promptly acknowledged and addressed.

Background: Substance use is a complex condition with multidimensional determinants. The present study aims to find the prevalence and determinants of substance use among young people attending primary healthcare centers in India. Methods: A multicentric cross-sectional study was conducted across 15 states in India on 1,630 young people (10-24 years) attending primary health centers. The Alcohol, Smoking, and Substance Involvement Screening Test (ASSIST) was used to capture data on substance use. The degree of substance involvement was assessed and multivariate regression analysis was conducted to determine the risk factors of substance use. Results: The prevalence of substance use was 32.8%, with a median substance initiation age of 18 years. Among the substance users, 75.5% began before completing adolescence. Tobacco (26.4%), alcohol (26.1%) and cannabis (9.5%) were commonly consumed. Sociodemographic determinants included higher age, male gender, urban residence, positive family history, northeastern state residence and lower socioeconomic class. Over 80% of users had moderate or high involvement. Conclusions: High substance use prevalence among young people in Indian healthcare centers underscores the urgency of targeted intervention. Insights on determinants guide effective prevention strategies for this complex public health issue.
RESUMEN
Context: There has been an increasing prevalence of hypertension (HTN) affecting all populations of the world including the special occupational groups and industries workers. Aims: To estimate the prevalence of hypertension and to determine the associated factors among industrial workers in the Haryana state of India. Settings and Design: A cross-sectional study was conducted among 323 industrial workers of Faridabad, Haryana. Materials and Methods: A semi-structured and validated questionnaire was used to collect information regarding sociodemographic characteristics of the workers, their personal habits, and occupational history. The investigator also recorded the height, weight, blood pressure, blood glucose, and lipid profile of the workers. Statistical Analysis Used: Analysis of the data was done using SPSS Vs 21. Results: The prevalence of hypertension among industrial workers was 48.6%. Age of the worker, presence of smoking or alcohol consumption, having a longer duration of employment, and having deranged total cholesterol/TG/LDL-C levels, diabetes, or obesity were found to be independently associated with hypertension. Conclusion: Screening is required for early detection and prevention of complications. Lifestyle modification is of utmost importance. Employers should implement guidelines issued by the government to protect the health of the productive population.
RESUMEN
BACKGROUND: The information on healthcare expenditure is crucial to know the impact of the pandemic on public health budgets, thereby correctly managing the ongoing crisis and preparing for subsequent waves. OBJECTIVE: To estimate the length of stay and cost incurred on COVID-19 patients who died in the ICU. METHODS: It is a record-based descriptive study conducted on 76 deceased COVID-19 patients admitted to the ICU of a dedicated COVID-19 hospital (DCH) between April and October 2020. Central Government Health Services (CGHS) package rate list, Delhi-NCR, was used as a reference for the cost of the ICU bed, ventilator, investigations, and procedures. RESULTS: The median duration of stay in the hospital was 12 days, and in the ICU, it was eight days. The median total cost of managing the patient was 91,235.6 INR; of this, the median total cost for ICU stay per patient was 6,904 INR. The major proportion of total expenses was contributed by personal protective equipment (PPE) kits, an average of 11,091.33 INR per month. The median cost of stay in the ICU, on the ventilator, in the ward, and mean cost of investigations were higher among those with associated co-morbidities. CONCLUSION: Most elderly male with co-morbidities lost their battle after ventilator support in the ICU. Patients with co-morbidities and severe disease not only have a long duration of hospitalization and poor survival rate but also fetch an economic burden close to one lakh on the institute.
RESUMEN
Transcriptome-wide survey divulged a total of 181 ABC transporters in G. glabra which were phylogenetically classified into six subfamilies. Protein-Protein interactions revealed nine putative GgABCBs (-B6, -B14, -B15, -B25, -B26, -B31, -B40, -B42 &-B44) corresponding to five AtABCs orthologs (-B1, -B4, -B11, -B19, &-B21). Significant transcript accumulation of ABCB6 (31.8 folds), -B14 (147.5 folds), -B15 (17 folds), -B25 (19.7 folds), -B26 (18.31 folds), -B31 (61.89 folds), -B40 (1273 folds) and -B42 (51 folds) was observed under the influence of auxin. Auxin transport-specific inhibitor, N-1-naphthylphthalamic acid, showed its effectiveness only at higher (10 µM) concentration where it down regulated the expression of ABCBs, PINs (PIN FORMED) and TWD1 (TWISTED DWARF 1) genes in shoot tissues, while their expression was seen to enhance in the root tissues. Further, qRT-PCR analysis under various growth conditions (in-vitro, field and growth chamber), and subjected to abiotic stresses revealed differential expression implicating role of ABCBs in stress management. Seven of the nine genes were shown to be involved in the stress physiology of the plant. GgABCB6, 15, 25 and ABCB31 were induced in multiple stresses, while GgABCB26, 40 & 42 were exclusively triggered under drought stress. No study pertaining to the ABC transporters from G. glabra is available till date. The present investigation will give an insight to auxin transportation which has been found to be associated with plant growth architecture; the knowledge will help to understand the association between auxin transportation and plant responses under the influence of various conditions.

The recent advancements in sequencing technologies and informatic tools promoted a paradigm shift to decipher the hidden biological mysteries and transformed the biological issues into digital data to express both qualitative and quantitative forms. The transcriptomic approach, in particular, has added new dimensions to the versatile essence of plant genomics through the large and deep transcripts generated in the process. This has enabled the mining of super families from the sequenced plants, both model and non-model, understanding their ancestry, diversity, and evolution. The elucidation of the crystal structure of the WRKY proteins and recent advancement in computational prediction through homology modeling and molecular dynamic simulation has provided an insight into the DNA-protein complex formation, stability, and interaction, thereby giving a new dimension in understanding the WRKY regulation. The present review summarizes the functional aspects of the high volume of sequence data of WRKY transcription factors studied from different species, till date. The review focuses on the dynamics of structural classification and lineage in light of the recent information. Additionally, a comparative analysis approach was incorporated to understand the functions of the identified WRKY transcription factors subjected to abiotic (heat, cold, salinity, senescence, dark, wounding, UV, and carbon starvation) stresses as revealed through various sets of studies on different plant species. The review will be instrumental in understanding the events of evolution and the importance of WRKY TFs under the threat of climate change, considering the new scientific evidences to propose a fresh perspective.

The study reports cloning and characterization of complete biosynthetic gene cluster committed to glycyrrhizin biosynthesis along with their corresponding promoter regions from Glycyrrhiza glabra. The identified genes namely, ß-amyrin synthase, ß-amyrin-11-oxidase, 11-oxo-beta-amyrin 30-oxidase and UDP-dependent glucosyltransferase, were hetrologously expressed in Nicotiana benthamiana for functional validation. The phyto-hormone, naphthalene acetic acid was shown to prompt maximum up regulation (1.3-14.0 folds) of all the genes, followed by gibberellic acid (0.001-10.0 folds) and abscisic acid (0.2-7.7 folds) treatments. The promoter-GUS fusion constructs infiltrated leaves of the identified genes exhibited enhanced promoter activity of ß-amyrin synthase (3.9 & 3.0 folds) and 11-oxo-beta-amyrin 30-oxidase (3.6 & 3.2 folds) under the GA3 and NAA treatments, respectively as compared to their respective untreated controls. The transcriptional control of the three phytohormones studied could be correlated to the cis-responsive elements present in the upstream regions of the individual genes. The study provided an insight into the intricate interaction between hormone-responsive motifs with the corresponding co-expression of the glycyrrhizin biosynthetic pathway genes. The study will help in understanding the phytohormones-mediated regulation of glycyrrhizin biosynthesis and its modulation in the plant.

Objectives: This study was undertaken to determine the characteristics of COVID-19 deaths during the second wave and to compare these characteristics with the mortality during the first wave in a dedicated COVID hospital (DCH). Study Design: It was a hospital record-based descriptive study. Methodology: The study was conducted in a tertiary care COVID hospital, using a standard death audit proforma. The data were analyzed to know various demographic characteristics and factors related to mortality during the second wave from March to June 2021. The findings were compared with the mortality data during the first wave from April to July 2020 at the same hospital. Results: A total of 264 deaths occurred at the center during the study period with a mortality rate of 22.8%. Male cases were more in number, the age group was 21-70 years, the highest number of mortality was seen in the mid of the study period, duration of stay was five days on average and common causes of death were pneumonia alone or with acute respiratory distress syndrome with sepsis. In comparison to the first wave, the mortality rate was four times higher, the age group was younger and opportunistic infections viz. mucormycosis and aspergillosis were present during the second wave. Conclusion: The mortality rate was significantly higher and the younger age groups were involved during the second wave, with opportunistic fungal infections due to the use of immunomodulators.
RESUMEN
BACKGROUND: COVID-19 pandemic has havocked the entire world and India has not been spared. The focus is not only on the containment but on the reduction in mortality also. The objective of the study was to know the trend of COVID-19 deaths in a 510-bedded dedicated COVID-19 hospital and to determine the cause of death and various factors associated with these deaths. METHOD: A descriptive study was conducted in a COVID-dedicated hospital setting to analyze deaths occurring during April--July, 2020 using a standard death audit proforma. RESULTS: A total number of 95 COVID-19 patients died in ICU. The mortality rate among ICU patients varied from 24.6% to 52.9%. Most of the cases were referred from other hospitals. About 64% of the deceased was admitted in severe condition and 34% of cases were referred on ventilator support. The week-wise trend revealed a positive association between the number of deaths and the number of referred cases as well as the number of patients received on ventilator support and in severe condition. About one-third of cases were late in seeking treatment at health centers with the same weekly trend. Being unaware of the condition (1%) and the stigma associated with the disease (32%) were the reasons behind it. Common direct causes of death were pneumonia (73%), pneumonia complicated with sepsis (16%), and acute respiratory disease syndrome (ARDS) (7%). CONCLUSION: High case fatality rate in the ICU of a referral COVID-dedicated hospital is mainly because of the admission of patients in severe conditions.
RESUMEN
Squalene epoxidase (SQE) is a crucial regulatory enzyme for the biosynthesis of several important classes of compounds including sterols and triterpenoids. The present paper identified and characterised five SQE genes (GgSQE1 to GgSQE5) from Glycyrrhiza glabra through transcriptome data mining and homology-based cloning, for the first time. The phylogenetic analysis implied their functional divergence. The ORF corresponding to one of the five SQEs, namely, GgSQE1, was cloned and studied for its function in a heterologous system, following transient and stable expressions. The transient expression followed by GgSQE1 encoding protein purification suggested approximately 58.0-kDa protein following the predicted molecular mass of the deduced protein. The gene expression profiling based on qRT-PCR indicated its highest expression (6.4-folds) in the 10-month-old roots. Furthermore, ABA (12.4-folds) and GA3 (2.47) treatments upregulated the expression of GgSQE1 in the shoots after 10 and 12 hours, respectively, which was also reflected in glycyrrhizin accumulation. The inductive effects of ABA and GA3 over GgSQE1 expression were also confirmed through functional analysis of GgSQE1 promoters using GUS fusion construct. Stable constitutive expression of GgSQE1 in Nicotiana tabacum modulated the sterol contents. The study could pave the way for understanding the metabolic flux regulation concerning biosynthesis of related sterols and triterpenoids.

INTRODUCTION: Menstruation is a natural phenomenon among women who experience shedding of blood for 1-7 days every month which usually starts between age 11 and 14 years and continues until menopause at about 51 years of age. It is important to maintain menstrual hygiene, as poor practices increase vulnerability to reproductive and urinary tract infections. The present study was conducted with an aim to investigate the impact of focused group discussion (FGD) compared to didactic lectures (DLs) on the menstrual hygiene knowledge and practices. METHODS: The present cross-sectional study was conducted among 649 school girls during January to August 2019 using a convenience sampling technique. After collecting baseline information using a pretested, predesigned, standardized questionnaire, the participants in the control and intervention groups were exposed for the DLs and FGD, respectively, and 1 month after such intervention, the same questionnaire was again self-administered by participants. All tests were performed at a 5% level of significance using SPSS (version 22.0). RESULTS: The baseline characteristics of both the groups such as participants' mean age, mean age of menarche, mother's literacy status, religion, type of family, and socioeconomic status were comparable. There was a difference in the knowledge and practice mean score of participants in the control group for pre- and postintervention, which was highly statistically significant (P < 0.001). CONCLUSIONS: This study reveals that menstrual hygiene is far from satisfactory among most of the school girls. The DLs and FGD have improved the menstrual hygiene knowledge and practices among school girls.
RESUMEN
The study reports 147 full-length WRKY genes based on the transcriptome analysis of Glycyrrhiza genus (G. glabra and G. uralensis). Additional motifs in G. glabra included DivIVA (GgWRKY20) and SerS Superfamily (GgWRKY21) at the C-terminal, and Coat family motifs (GgWRKY55) at the N-terminal of the proteins, while Exo70 exo cyst complex subunit of 338 amino acid (GuWRKY9) was present at the N-terminal of G. uralensis only. Plant Zn cluster super-family domain (17 WRKYs) and bZIP domain (2 WRKYs) were common between the two species. Based on the number of WRKY domains, sequence alignment and phylogenesis, the study identified GuWRKY27 comprising of 3 WRKY domains in G. uralensis and a new subgroup-IIf (10 members), having novel zinc finger pattern (C-X4-C-X22-HXH) in G. glabra. Multiple WRKY binding domains (1-11) were identified in the promoter regions of the GgWRKY genes indicating strong interacting network between the WRKY proteins. Tissue-specific expression of 25 GgWRKYs, under normal and treated conditions, revealed 11 of the 18 induction factor triggered response corroborating to response observed in AtWRKYs. The study identified auxin-responsive GgWRKY 55 & GgWRKY38; GA3 responsive GgWRKYs15&59 in roots and GgWRKYs8, 20, 38, 57 &58 in the shoots of the treated plant. GgWRKYs induced under various stresses included GgWRKY33 (cold), GgWRKY4 (senescence), GgWRKYs2, 28 & 33 (salinity) and GgWRKY40 (wounding). Overall, 23 GgWRKYs responded to abiotic stress, and 17 WRKYs were induced by hormonal signals. Of them 13 WRKYs responded to both suggesting inter-connection between hormone signalling and stress response. The present study will help in understanding the transcriptional reprogramming, protein-protein interaction and cross-regulation during stress and other physiological processes in the plant.

BACKGROUND: Severe acute malnutrition (SAM) is a salient health problem in India. Federation of Indian Chamber of Commerce and Industry (FICCI) Research and Analysis Centre, New Delhi, prepared nutreal equivalent to ready-to-use therapeutic food by World Health Organization (WHO) for the management of SAM and defined food like homemade diet. OBJECTIVE: To compare acceptability and efficacy of nutreal over defined food for the management of SAM. METHODS: One hundred twelve children aged less than 5 years with SAM were enrolled as per the standard of WHO. Children were randomized into 2 groups to receive nutreal (n = 56) and defined food (n = 56) in unlimited amounts for 42 consecutive days and extended by 2 weeks as per demand. Calorie and protein intake, weight, and mid-upper arm circumference (MUAC) were recorded daily. RESULTS: Age range was 8 to 45 months. Ninety-three percent of children eagerly accepted nutreal but 7% does not. Whereas in the defined food group, 68% accepted eagerly, 30% did not accept eagerly, and 1.8% accepted poorly ( P = .004). At enrollment, mean weight in the nutreal group was 6.44 ± 1.60 kg and in the defined food group was 8.69 ± 1.76 kg, with MUAC in the nutreal group being 11.12 ± 0.47 cm and in the defined food group being 11.54 ± 0.34 cm. Mean weight in the nutreal and defined food groups at eighth week of intervention was 7.97 ± 1.8 kg and 9.71 ± 1.8 kg ( P < .001), respectively. Mid-upper arm circumference at eighth week was 12.10 ± 0.29 cm in the nutreal group and 12.49 ± 0.50 cm in the defined group ( P < .001). CONCLUSION: Acceptability, mean weight gain, and MUAC in the nutreal group are greater than the defined food.
RESUMEN
An efficient and reproducible protocol has been developed for in vitro propagation of Pithecellobium dulce (Roxb.) Benth (a multipurpose leguminous tree) from field grown nodal segments (axillary bud). Shoot bud induction occurred from nodal explants of 15-years-old tree on Murashige and Skoog (MS) basal medium supplemented with 4.4 µM 6-benzyladenine (BA) and multiplication was achieved on MS medium supplemented with 4.4 µM BA + 0.73 µM phenylacetic acid (PAA) i.e. up to 7 shoot buds in the period of 5-6 weeks. Addition of adenine sulphate (AdS) to this medium further enhanced the number of shoot buds up to 10. Proliferating shoot cultures were established by repeatedly subculturing primary culture on fresh medium (MS + 4.4 µM BA + 0.73 µM PAA) after every 25 days. In vitro rooting was achieved on MS medium supplemented with 2.46 µM Indole-3-butyric acid (IBA) + 41.63 µM activated charcoal (AC). The micropropagated shoots with well developed roots were acclimatized in green house in pots containing sand, soil and manure (1:1:1). Genetic stability of micropropagated clones was evaluated using Random amplified polymorphic DNA (RAPD) and Inter simple sequence repeat (ISSR) markers. The amplification products were monomorphic in micropropagated plants and similar to those of mother plant. No polymorphism was detected revealing the genetic uniformity of micropropagated plants. This is the first report of an efficient protocol for regeneration of P. dulce through organogenesis, which can be used for further genetic transformation and pharmaceutical purposes.
