RESUMEN

Long COVID (LC) refers to a condition characterized by a variety of lingering symptoms that persist for more than 4 to 12 weeks following the initial acute SARS-CoV-2 infection. Recent research has suggested that the FOXP4 gene could potentially be a significant factor contributing to LC. Owing to that, this study investigates FOXP4's role in LC by analyzing public datasets to understand its evolution and expression in diverse human populations and searching for drugs to reduce LC symptoms. Population genetic analysis of FOXP4 across human populations unmasks distinct genetic diversity patterns and positive selection signatures, suggesting potential population-specific susceptibilities to conditions like LC. Further, we also observed that FOXP4 experiences high expression during LC. To identify potential inhibitors, drug screening analysis identifies synthetic drugs like Glisoxepide, and natural compounds Kapurimycin A3 produced from Streptomyces sp, and Cucurbitacin B from Begonia nantoensis as promising candidates. Overall, our research contributes to understanding how FOXP4 may serve as a therapeutic target for mitigating the impact of LC.

RESUMEN

INTRODUCTION: Indian cigarillos (bidi) are low-cost alternatives to cigarettes with only 22% imposed taxes, and turnover of upto INR 4 million per annum exempted from taxation. This paper estimates revenue implications and potential loss of life years (YLLs) averted, if bidi industry is subjected to increased regulations and taxation. METHODS: Revenue estimated at 10% increased regulation and 100% regulation were calculated, followed by estimates at taxes equivalent to cigarettes and World Health Organization - Framework Convention on Tobacco Control (WHO-FCTC) recommendation. Price elasticity was considered to assess demand. Price change in separate fractions (previously regulated and unregulated) were calculated to obtain potential YLLs averted. RESULTS: Current revenue of USD 59.25 million is projected to increase to USD 179.25 million with 695,159 averted YLLs at cigarette equivalent taxes and 10% increased regulation; USD 639.38 million with 4,527,597 averted YLLs with 100% regulation; USD 54.75 million, at WHO recommended taxes with 2,233,740 YLLs averted at 10% increased regulation, and 10,486,192 YLLs at 100% regulation. CONCLUSION: Proposed estimates are inline with WHO recommendations as they consider price elasticity and suggest substantial increase in revenue, while averting YLLs. A national action is needed to drive the policy decisions towards increased regulation and taxation and revision of India's tobacco control legislation. IMPLICATIONS: Our study presented empirical evidence of how the currently underutilized tool of taxation, as proposed in the WHO-FCTC, can be utilized to decrease bidi smoking prevalence and save measurable life years while generating government revenue simultaneously. While the revenue statistics counter the misleading tobacco industry narratives, the projected reduction in mortality will be seen as an irrefutable driving force for policy reforms, targeted at strategic increase in regulation and taxation of the traditional Indian cigarillos industry.

RESUMEN

High-valent metal-oxo species serve as key intermediates in the activation of inert C-H bonds. Here, we present a comprehensive DFT analysis of the parameters that have been proposed as influencing factors in modeled high-valent metal-oxo mediated C-H activation reactions. Our approach involves utilizing DFT calculations to explore the electronic structures of modeled FeIVO (species 1) and CoIVO ↔ CoIII-O˙ (species 2), scrutinizing their capacity to predict improved catalytic activity. DFT and DLPNO-CCSD(T) calculations predict that the iron-oxo species possesses a triplet as the ground state, while the cobalt-oxo has a doublet as the ground state. Furthermore, we have investigated the mechanistic pathways for the first C-H bond activation, as well as the desaturation of the alkanes. The mechanism was determined to be a two-step process, wherein the first hydrogen atom abstraction (HAA) represents the rate-limiting step, involving the proton-coupled electron transfer (PCET) process. However, we found that the second HAA step is highly exothermic for both species. Our calculations suggest that the iron-oxo species (Fe-O = 1.672 Å) exhibit relatively sluggish behavior compared to the cobalt-oxo species (Co-O = 1.854 Å) in C-H bond activation, attributed to a weak metal-oxygen bond. MO, NBO, and deformation energy analysis reveal the importance of weakening the M-O bond in the cobalt species, thereby reducing the overall barrier to the reaction. This catalyst was found to have a C-H activation barrier relatively smaller than that previously reported in the literature.

RESUMEN

BACKGROUND: The majority of persons with dementia in Sweden reside in their own homes with support from family members. Approximately, 12% of persons with dementia have immigrant background. Within the next 20 years, the number of persons with dementia who are non-ethnic Swedes is said to double. Family caregivers with immigrant backgrounds are noted to receive less support in the community than ethnic Swedes and rate their health status lower than ethnic Swedish peers. The Swedish National Board of Health and Welfare have highlighted the importance of follow-up support for family caregivers with immigrant backgrounds as there is a recognized gap in research and available information tailored to meet the needs of this group. PURPOSE OF THE STUDY: The purpose of the study is to test effectiveness of an mHealth based intervention through which community social workers can improve caregiving competence of non-European immigrant family caregivers of people with dementia living at home in Sweden. The overarching aim is to reduce caregiver burden and depressive symptoms, and improve quality of life. METHODS: A randomized controlled trial (RCT) including wait list control group will be performed consisting of an intervention group (A, n = 44) and a wait list control group (B, n = 44), totaling a sample size of 88. On completion of the 10-weeks long intervention in the intervention group, the intervention will be delivered to group B. Effect of the intervention will be analyzed between and within groups over time. The content of the educational component of the intervention is inspired by the iSupport manual developed by the World Health Organization. The contents, in the form of a booklet, aims to equip the family caregivers with structured information on understanding dementia as a condition and its management at home, including self-care guidance designed specifically for family caregivers themselves. DISCUSSION: Similar telephone-delivered intervention studies targeted for family caregivers to persons with dementia are ongoing in Malaysia and will start in India using the same booklet adapted to the local context. These studies will provide evidence on the effectiveness of using digital technologies to deliver support to those who may not be reached or adequately served by the traditional healthcare system. TRIAL REGISTRATION: ISRCTN registry, Registration number ISRCTN64235563.

RESUMEN

BACKGROUND: Gestational diabetes mellitus (GDM) is frequently misdiagnosed during pregnancy. There is an abundance of evidence, but little is known regarding the regional prevalence estimates of GDM in India. This systematic review and meta-analysis aims to provide valuable insights into the national and regional prevalence of GDM among pregnant women in India. METHODS: We conducted an initial article search on PubMed, Scopus, Google Scholar, and ShodhGanga searches to identify quantitative research papers (database inception till 15th June,2022). This review included prevalence studies that estimated the occurrence of GDM across different states in India. RESULTS: Two independent reviewers completed the screening of 2393 articles, resulting in the identification of 110 articles that met the inclusion criteria, which collectively provided 117 prevalence estimates. Using a pooled estimate calculation (with an Inverse square heterogeneity model), the pooled prevalence of GDM in pregnant women was estimated to be 13%, with a 95% confidence interval (CI) ranging from 9 to 16%.. In India, Diabetes in Pregnancy Study of India (DIPSI) was the most common diagnostic criteria used, followed by International Association of Diabetes and Pregnancy Study Groups (IADPSG) and World Health Organization (WHO) 1999. It was observed that the rural population has slightly less prevalence of GDM at 10.0% [6.0-13.0%, I2=96%] when compared to the urban population where the prevalence of GDM was 12.0% [9.0-16.0%, I2 = 99%]. CONCLUSIONS: This review emphasizes the lack of consensus in screening and diagnosing gestational diabetes mellitus (GDM), leading to varied prevalence rates across Indian states. It thoroughly examines the controversies regarding GDM screening by analyzing population characteristics, geographic variations, diagnostic criteria agreement, screening timing, fasting vs. non-fasting approaches, cost-effectiveness, and feasibility, offering valuable recommendations for policy makers. By fostering the implementation of state-wise screening programs, it can contribute to improving maternal and neonatal outcomes and promoting healthier pregnancies across the country.

RESUMEN

BACKGROUND: Transgender people comprise an estimated 0.3-0.5% (25 million) of the global population. The public health agenda focuses on understanding and improving the health and well-being of gender minorities. Transgender (TG) persons often have complex healthcare needs and suffer significant health disparities in multiple arenas. The international literature suggests that this community is at a higher risk of depression, and other mental health problems, including HIV. Many transgender people experience gender dysphoria and seek specific medical needs such as sex reassignment surgeries, implants, hormonal therapies, etc., but are unable to access these services due to financial or social reasons. The objective of this study was to assess the healthcare needs and associated barriers experienced by transgender people in Western Rajasthan. METHODOLOGY: A qualitative study was carried out in which multilevel stakeholder interviews were conducted using interview and focus group discussion guides. Data was analyzed using the qualitative thematic analysis technique. RESULTS: Findings reveal that transgender people have expressed their need to access health services for general health needs, including but not limited to mental health, non-communicable diseases, and infectious diseases. Barriers to healthcare services were identified on 3 levels: health system, social and personal. Health system barriers include policy, accessibility, affordability, and acceptability issues. Social factors such as inadequate housing, education, and job opportunities also play an important role in affecting the individual's health-seeking behavior. The knowledge of healthcare providers in this context was also limited in context of health insurance schemes, package of services available for transgenders and the importance of gender sensitive healthcare. CONCLUSION: Transgender people expressed the need for mental health services, programs targeting nutritional improvement, gender-affirmation procedures besides regular screening of non-communicable diseases as operational for males and females. Levels of barriers have been identified at various levels ranging from absence of targeted policies to individual behavior.

RESUMEN

BACKGROUND: The purpose of this study is to provide comprehensive and efficient pre-anesthesia counseling (PAC) utilizing audiovisual aids and to examine their effect on parental anxiety. METHODS: For this prospective, controlled study, 174 parents were recruited and randomized into three groups of 58 (Group A: video, Group B: brochure, and Group C: verbal). During pre-anesthesia counseling, the parent was provided with a detailed explanation of preoperative preparation, fasting instructions, transport to the operating room, induction, the emergence of anesthesia, and nursing in the post-anesthesia care unit based on their assigned group. We evaluated parental anxiety using Spielberger's State-Trait Anxiety Inventory before and after the pre-anesthesia counseling. RESULTS: The results of our study show a statistically significant difference in the final mean STAI scores among the three groups (Group A: 34.69 ± 5.31, Group B: 36.34 ± 8.59, and Group C: 43.59 ± 3.39; p < .001). When compared to the brochure and verbal groups, the parents in the video group have the greatest difference in mean baseline and final Spielberger's State-Trait Anxiety Inventory scores (12.207 ± 5.291, p .001). CONCLUSION: The results of our study suggest that pre-anesthesia counseling by video or a brochure before the day of surgery is associated with a higher reduction in parental anxiety when compared to verbal communication.

RESUMEN

Forced intercalation peptide nucleic acids (FIT-PNAs) are DNA mimics that act as RNA sensors. The sensing event occurs due to sequence-specific RNA hybridization, leading to a substantial increase in fluorescence. The fluorophore in the FIT-PNA is termed a surrogate base. This molecule typically replaces a purine in the PNA sequence. BisQ is a surrogate base that connects two quinolines via a monomethine bond. BisQ-based FIT-PNAs have excellent biophysical features that include high brightness and red-shifted emission (λem, max = 613 nm). In this report, we detail two chemical approaches that allow for the facile synthesis of the BisQ PNA monomer. In both cases, the key compound used for the synthesis of BisQ-CH2COOH is the tBu-ester-modified quinoline synthon (compound 5). Subsequently, one method uses the Alloc acid-protected PNA backbone, whereas the other uses the tBu ester-protected PNA backbone. In the latter case, the overall yield for BisQ acid (compound 7) and BisQ PNA monomer syntheses was 61% in six synthetic steps. This is a substantial improvement to the published procedures to date (7% total yield). Lastly, we have prepared an 11-mer FIT-PNA with either BisQ or thiazole orange (TO) and studied their photophysical properties. We find superior photophysical properties for the BisQ FIT-PNA in terms of the brightness and selectivity, highlighting the added value of using this surrogate base for RNA sensing.

RESUMEN

BACKGROUND: In tuberculosis (TB) care and management, there are practical challenges existing at the patient-provider level leading to implementation barriers at the primary care level. OBJECTIVES: The objective of the study is to explore the challenges and barriers faced by people with TB and health-care workers in TB care and management. MATERIALS AND METHODS: This study was done as a part of a community intervention study between November 2021 and December 2022. Twenty interviews were taken with treatment for TB (n = 7) and health-care personnel (n = 13). Health-care personnel include nursing staff, medical officers, laboratory technicians, community health workers, and medical personnel from tertiary care hospital. Participants were recruited across all levels of health-care systems. Interviews were carried out in the Hindi language, audio recorded, and translated to English. Participants were asked about their experiences of challenges and barriers faced during TB care and management. Qualitative data were coded, and thematic analysis was done manually. RESULTS: The challenges and barriers at the level of people with TB were issues with communication between providers and people with TB, out-of-pocket expenditure, poor adherence to medicines, lack of proper diet, gender issues, and stigma. The challenges and barriers at the level of health-care providers were a lack of infrastructure and logistics, lack of awareness, COVID-19-related issues, lack of workforce, and technical issues. CONCLUSION: Communication between providers and people with TB must be improved to improve the drug adherence and satisfaction of the end user. Proper funding must be provided for the TB programs. People with TB must be counseled properly regarding the free health care services available near their homes to prevent out-of-pocket expenditure. These will help in fast-tracking the elimination of TB.

RESUMEN

This paper presents the results of two proficiency testing (PT) rounds conducted by the Export Inspection Agency (EIA) Chennai laboratory in 2021 for food testing laboratories in India. The PT program was designed in accordance with ISO/TS 22117, a standard for proficiency testing in food microbiology, and targeted Listeria monocytogenes and Salmonella spp as the organisms of focus. The samples were found to be stable and recoverable during the analysis, and all PT sample packages were delivered to participant laboratories in good condition. The participant laboratories reported high sensitivity rates of 100% for PT round 061021 M and 96.49% for PT round 050721 M. The accuracy rate in PT round 061021 M was 91.89% and 92.10% in case of PT round 050721 M. However, there were some false positive and false negative results reported by some participant laboratories in both PT rounds, which may have been caused by operational errors or inconsistencies in analysis. During the PT round 061021 M, out of a total of 38 participant laboratories, five laboratories reported false positive results and one laboratory reported a false negative result. Similarly, during the PT round 050721 M, six laboratories reported false positive results which resulted in their results being deemed unsatisfactory.
