RESUMEN
The escalating threat of antimicrobial resistance has become a global health crisis. Therefore, there is a rising momentum in developing biomaterials with self-sanitizing capabilities and inherent antibacterial properties. Despite their promising antimicrobial properties, metal nanoparticles (MNPs) have several disadvantages, including increased toxicity as the particle size decreases, leading to oxidative stress and DNA damage that need consideration. One solution is surface functionalization with biocompatible organic ligands, which can improve nanoparticle dispersibility, reduce aggregation, and enable targeted delivery to microbial cells. The existing research predominantly concentrates on the advancement of peptide-based hydrogels for coating materials to prevent bacterial infection, with limited exploration of developing surface coatings using organogels. Herein, we have synthesized organogel-based coatings doped with MNPs that can offer superior hydrophobicity, oleophobicity, and high stability that are not easily achievable with hydrogels. The self-assembled gels displayed distinct morphologies, as revealed by scanning electron microscopy and atomic force microscopy. The cross-linked matrix helps in the controlled and sustained release of MNPs at the site of bacterial infection. The synthesized self-assembled gel@MNPs exhibited excellent antibacterial properties against harmful bacteria such as Escherichia coli and Staphylococcus aureus and reduced bacterial viability up to 95% within 4 h. Cytotoxicity testing against metazoan cells demonstrated that the gels doped with MNPs were nontoxic (IC50 > 100 µM) to mammalian cells. Furthermore, in this study, we coated the organogel@MNPs on cotton fabric and tested it against Gram +ve and Gram -ve bacteria. Additionally, the developed cotton fabric exhibited superhydrophobic properties and developed a barrier that limits the interaction between bacteria and the surface, making it difficult for bacteria to adhere and colonize, which holds potential as a valuable resource for self-cleaning coatings.

Introduction: The Maternal Mortality Rate (MMR) is one of the most important health indicators of a country. In India, MMR has decline from 130 to 113 per 100,000 live births between 2014 and 2018, however, there are wide disparities in utilization of maternal health services (MHS) among different states and across different socioeconomic groups within the states. Although the government is providing MHS through various health programs in India, there are several non medical factors leading to the underutilization of MHS services. Objective: To map and summarise the non-medical determinants of access and quality of MHS in India. Methods: We are conducting a scoping review of the published literature from 2000 till date in databases such as PubMed, Cochrane, Science Direct and CINAHL by including eligible qualitative as well as quantitative studies conducted in India. Data extraction and analysis will be conducted through a narrative integrative synthesis approach to summarize the non-medical determinants of access and quality of MHS in India and understand their mechanisms of influence.At the third SPINE20 summit 2022 which took place in Bali, Indonesia, in August 2022, 17 associations endorsed its recommendations. Results: We will summarise the non-medical determinants that influence the access and quality of MHS. Conclusion: This scoping review would help to understand and summarise the existing non-medical determinants of access and quality of MHS, highlight the research gaps and suggest potential modalities for improvement of access and quality of MHS.
RESUMEN
Background: Giant prolactinomas are rare; among them, the amyloidogenic variant, prolactinomas with extensive spherical amyloid deposits, are rare, with only 30 cases reported with recommendations of surgical management contrary to the routine prolactinoma's medical management. Case Description: We report here a case of giant amyloidogenic prolactinoma in a 32-year-old male patient who had a very atypical presentation in terms of clinical, radiological, and pathological features and responded to dopamine agonist therapy like a normal prolactinoma. Conclusion: Amyloidogenic giant prolactinomas are rare. Contrary to usual belief, even they remain medically responsive; however, more literature is required to decide their ideal management.

We report a first and interesting case of balloon-assisted deployment of a dislodged coronary stent. While performing a calcified left circumflex coronary artery (LCX) intervention, the drug-eluting coronary stent was dislodged in the osteoproximal segment of the calcified and tortuous LCX. The dislodged stent was rewired, progressively dilated with multiple balloons and, finally, a larger, balloon-mounted stent was pushed forward, positioned across the coronary lesion and deployed, resulting in distal thrombolysis in myocardial infarction (TIMI) III flow with good angiographic results. Rewiring the dislodged stent with subsequent balloon-assisted deployment in the lesion can be a solution for a dislodged coronary stent in the proximal vessel.
RESUMEN
Rapid urban population growth, the urbanization of poverty, and the proliferation of slums are being driven to a great extent by this dynamic form of globalization. Consequently, the multifaceted effects of globalization on the poor and low-income populations in the cities need to be better understood in this context, both at the individual level and within the community. Therefore, the present study was conducted to highlight the various determinants affecting the lives and enhancing the vulnerability of the dwellers of four slum settlements present in various areas of Jammu City, India. Emphasis was made to integrate biological, physical, social, and spatial facets of vulnerability to understand the complex dynamics of urban areas in developing countries. A descriptive survey design was used for questions concerning the social and environmental aspects. Social aspects including age, sex, education, religion, caste, profession, and family income that correspond to social stratification acted as baseline information, while both indoor and outdoor environments such as housing conditions, sanitation, personal habits, solid waste disposal, disaster proneness, and air and water pollution problems were taken into consideration to assess the environmental aspect. Results indicated that the slum settlement has a migratory population with permanent or temporary settlements. The status of education and skill level is poor which results in poor economic development and social well-being of the dwellers in slums. The study also identified vulnerability of the population on social and environmental front which could result into severe health issues. The study concluded and recommended policy planning specified for slums for uplifting such unprivileged populations.

BACKGROUND: Suspicious gallbladder wall thickening encountered during laparoscopic cholecystectomy poses challenges in its management. This study aims to address this problem by proposing a technique that involves laparoscopic transhepatic needle decompression and modified cystic plate cholecystectomy. METHODS: In this report, we describe the case of a 36-year-old female with symptomatic gallstone disease and ultrasound findings of a well-distended gallbladder with a uniform wall thickness. Diagnostic laparoscopy revealed a distended, tense gallbladder with suspicious areas of thickness. Transhepatic aspiration was performed for gallbladder decompression, followed by modified cystic plate cholecystectomy with preservation of the thin rim of liver tissue over the cystic plate. The gallbladder was removed in a specimen bag, and final histopathology showed a hyalinized gallbladder wall with calcification and pyloric gland metaplasia, with liver tissue adhered to the gallbladder wall (Video). RESULTS: The proposed technique aimed to minimize the risk of bile spillage and violation of oncological planes while maintaining surgical integrity. It offers a middle path between standard and extended cholecystectomy, reducing the chance of over- or under-treatment. This approach ensures patient safety, minimizes the need for conversion to open surgery, and preserves the tumour-tissue interface. CONCLUSION: Intraoperatively encountered suspicious gallbladder wall thickening can be effectively managed with laparoscopic transhepatic needle decompression and modified cystic plate cholecystectomy.

Tea, the major beverage worldwide, is one of the oldest commercial commodities traded from ancient times. Apart from many of its advantages, including health, socio-economic, climatic, and agro-ecological values, FAO has recognized that the tea value chain covering its growth in the field, processing and marketing, and finally, the hot cup at the user's hand needs to be made sustainable during all these stages. Tea generates a lot of waste in different forms in different stages of its growth and processing, and these wastes, if not managed properly, may cause environmental pollution. A planned utilization of these wastes as feedstocks for various processes can generate more income, create rural livelihood opportunities, help grow tea environmentally sustainable, avoid GHG emissions, and make a real contribution to SDGs. Thermochemical and biological conversion of tea wastes generates value-added products. This review provides an overview on the impacts of the tea wastes on the environment, tea waste valorization processes, and applications of value-added products. The application of value-added products for energy generation, wastewater treatment, soil conditioners, adsorbents, biofertilizers, food additives, dietary supplements, animal feed bioactive chemicals, dye, colourant, and phytochemicals has been reviewed. Further, the challenges in sustainable utilization of tea wastes and opportunities for commercial exploitation of value-added products from tea wastes have been reviewed.
RESUMEN
The need for wearable bioelectronics continues to grow, and this technology might significantly alter the medical field. In order to diagnose and treat a patient, conventional medicine takes a "reactive" approach and waits for symptoms to appear first. Therefore, it is preferable to progress toward continuous non-invasive wearable biomonitoring, a preventative strategy that may assist individuals in diagnosing or treating illnesses at the earliest stages, sometimes before any outward symptoms have appeared. Wearable physiological sensors, such as the Apple Watch and FitBit, have arrived on the market as a result of technology advances and have quickly become commonplace. However, few devices currently exist that can report directly on these biomarkers of relevance. This is mostly due to the challenges involved in real-time fluid sampling and generating correct readouts utilising extremely selective and sensitive sensors. Sweat is an excretory fluid that is only allowed to be used in order to reduce invasiveness, but this restriction places additional strain on sensors owing to the diluted concentration of the relevant biomarkers and the changes in pH, salinity, and other biophysical parameters that directly influence the read-out of real-time biosensors. Sweat is favoured amid slightly invasive biofluids due to its low concentration of interfering chemicals and the fact that it may be collected without touching the mucosal layers. This review offers a concise outline of the latest advances in sweat-based wearable sensors, their promise in healthcare monitoring, and the problems faced in analysis based on sweat.
RESUMEN
AIMS: Calmodulinopathy due to mutations in any of the three CALM genes (CALM1-3) causes life-threatening arrhythmia syndromes, especially in young individuals. The International Calmodulinopathy Registry (ICalmR) aims to define and link the increasing complexity of the clinical presentation to the underlying molecular mechanisms. METHODS AND RESULTS: The ICalmR is an international, collaborative, observational study, assembling and analysing clinical and genetic data on CALM-positive patients. The ICalmR has enrolled 140 subjects (median age 10.8 years [interquartile range 5-19]), 97 index cases and 43 family members. CALM-LQTS and CALM-CPVT are the prevalent phenotypes. Primary neurological manifestations, unrelated to post-anoxic sequelae, manifested in 20 patients. Calmodulinopathy remains associated with a high arrhythmic event rate (symptomatic patients, n = 103, 74%). However, compared with the original 2019 cohort, there was a reduced frequency and severity of all cardiac events (61% vs. 85%; P = .001) and sudden death (9% vs. 27%; P = .008). Data on therapy do not allow definitive recommendations. Cardiac structural abnormalities, either cardiomyopathy or congenital heart defects, are present in 30% of patients, mainly CALM-LQTS, and lethal cases of heart failure have occurred. The number of familial cases and of families with strikingly different phenotypes is increasing. CONCLUSION: Calmodulinopathy has pleiotropic presentations, from channelopathy to syndromic forms. Clinical severity ranges from the early onset of life-threatening arrhythmias to the absence of symptoms, and the percentage of milder and familial forms is increasing. There are no hard data to guide therapy, and current management includes pharmacological and surgical antiadrenergic interventions with sodium channel blockers often accompanied by an implantable cardioverter-defibrillator.

RESUMEN
Bacillus anthracis Ser/Thr protein kinase PrkC is necessary for phenotypic memory and spore germination, and the loss of PrkC-dependent phosphorylation events affect the spore development. During sporulation, Bacillus sp. can store 3-Phosphoglycerate (3-PGA) that will be required at the onset of germination when ATP will be necessary. The Phosphoglycerate mutase (Pgm) catalyzes the isomerization of 2-PGA and 3-PGA and is important for spore germination as a key metabolic enzyme that maintains 3-PGA pool at later events. Therefore, regulation of Pgm is important for an efficient spore germination process and metabolic switching. While the increased expression of Pgm in B. anthracis decreases spore germination efficiency, it remains unexplored if PrkC could directly influence Pgm activity. Here, we report the phosphorylation and regulation of Pgm by PrkC and its impact on Pgm stability and catalytic activity. Mass spectrometry revealed Pgm phosphorylation on seven threonine residues. In silico mutational analysis highlighted the role of Thr459 residue towards metal and substrate binding. Altogether, we demonstrated that PrkC-mediated Pgm phosphorylation negatively regulates its activity that is essential to maintain Pgm in its apo-like isoform before germination. This study advances the role of Pgm regulation that represents an important switch for B. anthracis resumption of metabolism and spore germination.

The present study reports a detailed life cycle assessment and cost-benefit analysis of a commercially viable Internal-Stack-Trickling Bio-Electrochemical Reactor (IS-TrickBER). IS-TrickBER used wastewater as a feedstock and converted that wastewater through electrochemical methods into low-grade fertilizer and produced electricity. IS-TrickBER was observed for its performance in terms of power output and wastewater treatment. IS-TrickBER exhibited up to 4.2 Wh net energy yield while treating 84.84L wastewater per day along with 92.17% COD removal and 38.23% Columbic efficiency during the operational run with real municipal wastewater. Based on daily net energy yield, up to 1457.6Wh yearly net energy yield can be expected. A comprehensive start-to-end life cycle assessment study associated with the manufacturing, and operational phases of IS-TrickBER was also conducted to ascertain its impact on the environment. The environmental impact through air emissions during the manufacturing stage can be minimized by changing the plastic balls used as packing material in the reactor. A detailed cost-benefit analysis was also conducted to understand its economic viability. Cost-benefit analysis of IS-TrickBER, based on net energy yield, shows that IS-TrickBER could compensate its installation cost within a few years. IS-TrickBER performed well in eliminating the chemical load of wastewater and simultaneous electricity generation. Due to its scalability, compactness, and low maintenance, IS-TrickBER can be a suitable candidate in real-time wastewater treatment.

RESUMEN
The demand for highly sensitive and selective gas sensors has been steadily increasing, driven by applications in various fields such as environmental monitoring, healthcare, and industrial safety. In this context, ternary alloy indium aluminum nitride (InAlN) semiconductors have emerged as a promising material for gas sensing due to their unique properties and tunable material characteristics. This work focuses on the fabrication and characterization of InAlN nanorods grown on sapphire substrates using an ultra-high vacuum magnetron sputter epitaxy with precise control over indium composition and explores their potential for acetone-gas-sensing applications. Various characterization techniques, including XRD, SEM, and TEM, demonstrate the structural and morphological insights of InAlN nanorods, making them suitable for gas-sensing applications. To evaluate the gas-sensing performance of the InAlN nanorods, acetone was chosen as a target analyte due to its relevance in medical diagnostics and industrial processes. The results reveal that the InAlN nanorods exhibit a remarkable sensor response of 2.33% at 600 ppm acetone gas concentration at an operating temperature of 350 °C, with a rapid response time of 18 s. Their high sensor response and rapid response make InAlN a viable candidate for use in medical diagnostics, industrial safety, and environmental monitoring.
RESUMEN
Biodiesel is an alternative, carbon-neutral fuel compared to fossil-based diesel, which can reduce greenhouse gas (GHGs) emissions. Biodiesel is a product of microorganisms, crop plants, and animal-based oil and has the potential to prosper as a sustainable and renewable energy source and tackle growing energy problems. Biodiesel has a similar composition and combustion properties to fossil diesel and thus can be directly used in internal combustion engines as an energy source at the commercial level. Since biodiesel produced using edible/non-edible crops raises concerns about food vs. fuel, high production cost, monocropping crisis, and unintended environmental effects, such as land utilization patterns, it is essential to explore new approaches, feedstock and technologies to advance the production of biodiesel and maintain its sustainability. Adopting bioengineering methods to produce biodiesel from various sources such as crop plants, yeast, algae, and plant-based waste is one of the recent technologies, which could act as a promising alternative for creating genuinely sustainable, technically feasible, and cost-competitive biodiesel. Advancements in genetic engineering have enhanced lipid production in cellulosic crops and it can be used for biodiesel generation. Bioengineering intervention to produce lipids/fat/oil (TGA) and further their chemical or enzymatic transesterification to accelerate biodiesel production has a great future. Additionally, the valorization of waste and adoption of the biorefinery concept for biodiesel production would make it eco-friendly, cost-effective, energy positive, sustainable and fit for commercialization. A life cycle assessment will not only provide a better understanding of the various approaches for biodiesel production and waste valorization in the biorefinery model to identify the best technique for the production of sustainable biodiesel, but also show a path to draw a new policy for the adoption and commercialization of biodiesel.
