Results of comprehensive genetic testing in patients presenting to a multidisciplinary inherited heart disease clinic in India.

OBJECTIVES: This study aims to analyze the results of comprehensive genetic testing in patients presenting to a dedicated multidisciplinary inherited heart disease clinic in India. METHODS: All patients presenting to our clinic from August 2017 to October 2023 with a suspected inherited heart disease and consenting for genetic testing were included. The probands were grouped into familial cardiomyopathies namely hypertrophic cardiomyopathy (HCM), dilated cardiomyopathy (DCM), arrhythmogenic cardiomyopathy (ACM) and peripartum cardiomyopathy (PPCM), channelopathies namely congenital long QT syndrome (LQTS) and Brugada syndrome (BrS), and heritable connective tissue disorder namely Marfan Syndrome (MFS). Next generation sequencing (NGS) was used, and pre-test and post-test counseling were provided to probands and cascade screening offered to relatives. RESULTS: Mean age of the subjects (n = 77; 48 probands, 29 relatives) was 43 ± 18 years, 68 % male and 44 % symptomatic, with 36 HCM, 3 DCM, 3 ACM, 1 PPCM, 3 LQTS, 1 BrS and 1 MFS probands. The diagnostic yield of NGS-based genetic testing was 31 %; variants of uncertain significance (VUS) were identified in 54 %; and 15 % were genotype-negative. Twenty-nine relatives from 18 families with HCM (n = 12), DCM (n = 3), ACM (n = 2) and MFS (n = 1) underwent genetic testing. The genotype positive probands/relatives and VUS carriers with strong disease phenotype and/or high risk variant were advised periodic follow-up; the remaining probands/relatives were discharged from further clinical surveillance. CONCLUSIONS: Genetic testing guides treatment and follow-up of patients with inherited heart diseases and should be carried out in dedicated multidisciplinary clinics with expertise for counseling and cascade screening of family members.

Monoolein-Based Wireless Capacitive Sensor for Probing Skin Hydration.

Capacitive humidity sensors typically consist of interdigitated electrodes coated with a dielectric layer sensitive to varying relative humidity levels. Previous studies have investigated different polymeric materials that exhibit changes in conductivity in response to water vapor to design capacitive humidity sensors. However, lipid films like monoolein have not yet been integrated with humidity sensors, nor has the potential use of capacitive sensors for skin hydration measurements been fully explored. This study explores the application of monoolein-coated wireless capacitive sensors for assessing relative humidity and skin hydration, utilizing the sensitive dielectric properties of the monoolein-water system. This sensitivity hinges on the water absorption and release from the surrounding environment. Tested across various humidity levels and temperatures, these novel double functional sensors feature interdigitated electrodes covered with monoolein and show promising potential for wireless detection of skin hydration. The water uptake and rheological behavior of monoolein in response to humidity were evaluated using a quartz crystal microbalance with dissipation monitoring. The findings from these experiments suggest that the capacitance of the system is primarily influenced by the amount of water in the monoolein system, with the lyotropic or physical state of monoolein playing a secondary role. A proof-of-principle demonstration compared the sensor's performance under varying conditions to that of other commercially available skin hydration meters, affirming its effectiveness, reliability, and commercial viability.

Folate-Mediated Targeting and Controlled Release: PLGA-Encapsulated Mesoporous Silica Nanoparticles Delivering Capecitabine to Pancreatic Tumor.

The discovery of specifically tailored therapeutic delivery systems has sparked the interest of pharmaceutical researchers considering improved therapeutic effectiveness and fewer adverse effects. The current study concentrates on the design and characterization of PLGA (polylactic-co-glycolic acid) capped mesoporous silica nanoparticles (MSN)-based systems for drug delivery for pH-sensitive controlled drug release in order to achieve a targeted drug release inside the acidic tumor microenvironment. The physicochemical properties of the nanoformulations were analyzed using TEM, zeta potential, AFM, TGA, FTIR, and BET analyses in addition to DLS size. The final formed PLGA-FoA-MSN-CAP and pure MSN had sizes within the therapeutic ranges of 164.5 ± 1.8 and 110.7 ± 2.2, respectively. Morphological characterization (TEM and AFM) and elemental analysis (FTIR and XPS) confirmed the proper capping and tagging of PLGA and folic acid (FoA). The PLGA-coated FoA-MSN exhibited a pH-dependent controlled release of the CAP (capecitabine) drug, showing efficient release at pH 6.8. Furthermore, the in vitro MTT test on PANC1 and MIAPaCa-2 resulted in an IC50 value of 146.37 µg/ml and 105.90 µg/ml, respectively. Mitochondrial-mediated apoptosis was confirmed from the caspase-3 and annexin V/PI flow cytometry assay, which displayed a cell cycle arrest at the G1 phase. Overall, the results predicted that the designed nanoformulation is a potential therapeutic agent in treating pancreatic cancer.

Scleral Buckle Removal: Long-Term Patient Outcomes.

PURPOSE: Scleral buckling has been a reliable treatment option in the repair of primary rhegmatogenous retinal detachments. Occasionally, patients require scleral buckles (SBs) to be removed for various reasons. While outcomes of SB removal have been investigated in this subset of patients, there has not been any large patient series to reach any conclusions. Long-term sequelae of SB removal are debated in the literature, specifically around the risk of redetachment. DESIGN: We performed a retrospective, observational study to evaluate the clinical indications for, and outcomes of, SB removal. PARTICIPANTS: No control patients in this retrospective, observational study. METHODS: Eighty-six individuals with a history of SB removal from June 1, 2000, to January 1, 2021, were followed from a large academic center and a private, retina-only practice in Chicago. Exclusion criteria were age of < 18 years and unplanned or self-explanted SB removal. MAIN OUTCOME MEASURES: Data extracted included patient symptoms before SB removal, indications for removal, resolution of symptoms following removal, rate of redetachment, and rate of additional ocular surgery. Secondary outcomes included identifying factors associated with poorer outcomes. RESULTS: Eighty-six eyes with history of SB removal were included with an average follow-up of 4 years. Approximately 60% were males and the mean age at the time of SB removal was 59 years. Leading indications for removal were exposure (61.63%), infection (20.93%), and diplopia/strabismus (19.77%). The average time from SB placement to removal was 12.28 ± 11.16 years. Most patients requiring SB removal presented with symptoms, specifically of pain and discomfort (65.12%), diplopia (22.09%), and drainage/discharge (18.60%). Of these patients, 86.59% experienced symptom resolution following SB removal. Notably, 6.56% (4 eyes) of all eyes with at least 1 year of follow-up experienced a redetachment requiring surgery. Within this subset, the average time from SB placement to removal was 2.05 ± 2.01 years and time to redetachment following removal was 15.95 ± 25.71 months. Nine percent of all eyes required additional strabismus or oculoplastic surgery. CONCLUSIONS: Scleral buckle removal provides a high rate of symptomatic relief and low risk of subsequent detachment. Nevertheless, close monitoring is warranted to monitor for recurrent retinal detachments.

CHARACTERISTICS, OUTCOMES, AND OPTICAL COHERENCE TOMOGRAPHY FEATURES OF MACULAR HOLE AFTER RHEGMATOGENOUS RETINAL DETACHMENT REPAIR.

PURPOSE: To investigate full-thickness macular holes (FTMHs) that develop after rhegmatogenous retinal detachment (RRD) repair. METHODS: Retrospective consecutive case series of patients who underwent RRD repair between 2015 and 2021 and subsequently developed FTMH. Twenty-three patients (23 eyes) were included. All eyes underwent pars plana vitrectomy + membrane peel for macular hole (MH) repair. RESULTS: The mean age at RRD diagnosis was 62 years and 52% were male. In total, 78% were macula-off RRDs. Fourteen eyes (60.9%) underwent pars plana vitrectomy alone, 7 (30.4%) underwent pars plana vitrectomy and scleral buckling, 1 (4.3%) underwent scleral buckling only, and 1 (4.3%) underwent pneumatic retinopexy. Median time from RRD repair to MH diagnosis was 116 days. Macula-off RRDs had a significantly lower time to MH diagnosis (mean 154 days, P < 0.05) than macula-on RRDs (mean 875 days). Twenty-one MH (91%) had optical coherence tomography evidence of an epiretinal membrane. Mean logMAR visual acuity at MH diagnosis was 1.05 (∼20/224) and significantly improved to 0.66 (∼20/91) at the final follow-up ( P < 0.001); 100% of MHs closed by the final follow-up. CONCLUSION: Pars plana vitrectomy for MH after RRD repair has a high closure rate and leads to significant VA improvement. MH formation after RRD repair may be associated with macula-off detachments and epiretinal membrane. Macula-off RRDs develop MH faster than macula-on RRDs.

Throughout this exploration, the review has emphasized the pivotal role of computational biologists, bioinformaticians, and biotechnologists in driving rapid advancements in clinical research and therapeutic development. By combining state-of-the-art computational techniques with insights from structural and molecular biology, the search for potent antiviral agents has been accelerated. The collaboration between these disciplines holds immense promise in addressing the transmissibility and virulence of SARS-CoV-2.

Biosynthesized nanoparticles: a novel approach for cancer therapeutics.

Nanotechnology has become one of the most rapid, innovative, and adaptable sciences in modern science and cancer therapy. Traditional chemotherapy has limits owing to its non-specific nature and adverse side effects on healthy cells, and it remains a serious worldwide health issue. Because of their capacity to specifically target cancer cells and deliver therapeutic chemicals directly to them, nanoparticles have emerged as a viable strategy for cancer therapies. Nanomaterials disclose novel properties based on size, distribution, and shape. Biosynthesized or biogenic nanoparticles are a novel technique with anti-cancer capabilities, such as triggering apoptosis in cancer cells and slowing tumour growth. They may be configured to deliver medications or other therapies to specific cancer cells or tumour markers. Despite their potential, biosynthesized nanoparticles confront development obstacles such as a lack of standardisation in their synthesis and characterization, the possibility of toxicity, and their efficiency against various forms of cancer. The effectiveness and safety of biosynthesized nanoparticles must be further investigated, as well as the types of cancer they are most successful against. This review discusses the promise of biosynthesized nanoparticles as a novel approach for cancer therapeutics, as well as their mode of action and present barriers to their development.

A Facile Synthesis of Flower-like Iron Oxide Nanoparticles and Its Efficacy Measurements for Antibacterial, Cytotoxicity and Antioxidant Activity.

The objective of this study was to investigate the rhombohedral-structured, flower-like iron oxide (Fe2O3) nanoparticles that were produced using a cost-effective and environmentally friendly coprecipitation process. The structural and morphological characteristics of the synthesized Fe2O3 nanoparticles were analyzed using XRD, UV-Vis, FTIR, SEM, EDX, TEM, and HR-TEM techniques. Furthermore, the cytotoxic effects of Fe2O3 nanoparticles on MCF-7 and HEK-293 cells were evaluated using in vitro cell viability assays, while the antibacterial activity of the nanoparticles against Gram-positive and Gram-negative bacteria (Staphylococcus aureus, Escherichia coli, and Klebsiella pneumoniae) was also tested. The results of our study demonstrated the potential cytotoxic activity of Fe2O3 nanoparticles toward MCF-7 and HEK-293 cell lines. The antioxidant potential of Fe2O3 nanoparticles was evidenced by the 1,1-diphenyl-2-picrylhydrazine (DPPH) and nitric oxide (NO) free radical scavenging assays. In addition, we suggested that Fe2O3 nanoparticles could be used in various antibacterial applications to prevent the spread of different bacterial strains. Based on these findings, we concluded that Fe2O3 nanoparticles have great potential for use in pharmaceutical and biological applications. The effective biocatalytic activity of Fe2O3 nanoparticles recommends its use as one of the best drug treatments for future views against cancer cells, and it is, therefore, recommended for both in vitro and in vivo in the biomedical field.

Hypercalcemia - An enigmatic cause of acute pancreatitis.

Background: Acute pancreatitis (AP) continues to be one of the common abdominal emergencies encountered in tertiary care hospitals. The majority of AP is caused by gall stones and alcohol. Hypercalcemia though uncommon has been reported to cause AP, recurrent AP, and chronic pancreatitis (CP). Aim: The aim of this study was to describe hypercalcemia-induced AP in different settings. Materials and Methods: In total 100 patients with AP, admitted from January 2021 to December 2021 at our center, etiologies were biliary (36%), alcohol (19%), idiopathic (21%), alcohol plus Biliary (5%), post-endoscopic retrograde cholangiopancreaticography (7%), drug-induced (6%), hypercalcemia (3%), and dengue infection (3%). Overall mortality was 11%. Results: In three patients with hypercalcemia-induced pancreatitis, causes of hypercalcemia were multiple myeloma, parathyroid adenoma leading to hyperparathyroidism, and hypervitaminosis D in association with hyperthyroidism. Conclusion: Hypercalcemia-induced AP is not a rare phenomenon and should be actively investigated to prevent further attacks of AP and progression to CP. Relevance for Patients: Hypercalcemia is a potentially treatable cause of AP and its identification will not only help to treat and prevent further episodes of pancreatitis but also to manage underlying diseases leading to hypercalcemia.

Heart rate variability as a marker of cardiovascular dysautonomia in post-COVID-19 syndrome using artificial intelligence.

INTRODUCTION: Cardiovascular dysautonomia comprising postural orthostatic tachycardia syndrome (POTS) and orthostatic hypotension (OH) is one of the presentations in COVID-19 recovered subjects. We aim to determine the prevalence of cardiovascular dysautonomia in post COVID-19 patients and to evaluate an Artificial Intelligence (AI) model to identify time domain heart rate variability (HRV) measures most suitable for short term ECG in these subjects. METHODS: This observational study enrolled 92 recently COVID-19 recovered subjects who underwent measurement of heart rate and blood pressure response to standing up from supine position and a 12-lead ECG recording for 60 s period during supine paced breathing. Using feature extraction, ECG features including those of HRV (RMSSD and SDNN) were obtained. An AI model was constructed with ShAP AI interpretability to determine time domain HRV features representing post COVID-19 recovered state. In addition, 120 healthy volunteers were enrolled as controls. RESULTS: Cardiovascular dysautonomia was present in 15.21% (OH:13.04%; POTS:2.17%). Patients with OH had significantly lower HRV and higher inflammatory markers. HRV (RMSSD) was significantly lower in post COVID-19 patients compared to healthy controls (13.9 ± 11.8 ms vs 19.9 ± 19.5 ms; P = 0.01) with inverse correlation between HRV and inflammatory markers. Multiple perceptron was best performing AI model with HRV(RMSSD) being the top time domain HRV feature distinguishing between COVID-19 recovered patients and healthy controls. CONCLUSION: Present study showed that cardiovascular dysautonomia is common in COVID-19 recovered subjects with a significantly lower HRV compared to healthy controls. The AI model was able to distinguish between COVID-19 recovered patients and healthy controls.

Portable Prussian Blue-Based Sensor for Bacterial Detection in Urine.

Bacterial infections can affect the skin, lungs, blood, and brain, and are among the leading causes of mortality globally. Early infection detection is critical in diagnosis and treatment but is a time- and work-consuming process taking several days, creating a hitherto unmet need to develop simple, rapid, and accurate methods for bacterial detection at the point of care. The most frequent type of bacterial infection is infection of the urinary tract. Here, we present a wireless-enabled, portable, potentiometric sensor for E. coli. E. coli was chosen as a model bacterium since it is the most common cause of urinary tract infections. The sensing principle is based on reduction of Prussian blue by the metabolic activity of the bacteria, detected by monitoring the potential of the sensor, transferring the sensor signal via Bluetooth, and recording the output on a laptop or a mobile phone. In sensing of bacteria in an artificial urine medium, E. coli was detected in ~4 h (237 ± 19 min; n = 4) and in less than 0.5 h (21 ± 7 min, n = 3) using initial E. coli concentrations of ~103 and 105 cells mL-1, respectively, which is under or on the limit for classification of a urinary tract infection. Detection of E. coli was also demonstrated in authentic urine samples with bacteria concentration as low as 104 cells mL-1, with a similar response recorded between urine samples collected from different volunteers as well as from morning and afternoon urine samples.

Biomolecules of mushroom: a recipe of human wellness.

The Indian system of medicine - Ayurveda says "When diet is wrong, medicine is of no use. When diet is correct, medicine is of no use". In this context, mushroom constitutes one of the major resources for nutraceuticals. Biomolecules of mushrooms have attracted the attention of researchers around the globe due to their proven healthy attributes. They have a plenitude of health-giving properties and these range from immunomodulatory, antiviral, antibacterial, antifungal, antioxidant, anti-inflammatory, antitumor, anticancer, anti-HIV, antidiabetic, anticholesterolic to antiarthritic activities.Mushrooms contain both primary and secondary metabolites. The primary metabolites provide energy while the secondary metabolite exhibits medicinal properties. Hence, the mushroom can be a recipe for human wellness and will play a significant role in fighting COVID-19 pandemics and other infectious diseases.The key findings suggested in this paper refer to the exploration of health and the healing traits of biomolecules of mushrooms. This article reviews the current status of the medicinal attributes of mushrooms and their biomolecules in different diseases such as cardiovascular, diabetes, reproductive diseases, cancer, and neurodegenerative diseases. The global malnutrition-related morbidity and mortality among children under five and lactating women presents a frightening picture and also a black spot on the human face. Malnutrition is responsible for more ill-health than any other cause. Mushrooms as a rich source of bioactive compounds can be claimed as "Best from the Waste" since they grow on the most abundant organic wastes of the Earth, the lignocellulosic substrate, and 'Best of the Rest' because they are excellent nutraceutical resources.

Parkinson's disease (PD) is one of the most debilitating brain diseases. Despite the availability of symptomatic treatments, response towards the health of PD patients remains scarce. To fulfil the medical needs of the PD patients, an efficacious and etiological treatment is required. In this review, we have compiled the information covering limitations of current therapeutic options in PD, novel drug targets for PD, and finally, the role of some critical beneficial natural products to control the progression of PD.

Two birds with one stone: oyster mushroom mediated bimetallic Au-Pt nanoparticles for agro-waste management and anticancer activity.

Agriculture has the most significant contribution in fulfilling the basic human need, sustaining life, and strengthening the economy of any country. To feed the exploding population of the world, there has been a quantum jump in the production of agricultural commodities, which has led to the production of a substantial considerable quantity of agricultural and agro-industrial wastes. The bulks of these wastes are lignocellulosic in nature and consist of three main polymeric constituents, i.e., cellulose, hemicellulose, and lignin, which are recalcitrant. The primary significant portions of these remain unutilized and are burnt in the field, leading to severe environmental aggression and wastage of resource. Farmers across the globe, including India, burn these agricultural wastes in their thousands of acre land, which contribute to spoiling the air quality index (AQI). This is very harmful, especially to children, pregnant women, old adults, and for patients suffering from respiratory diseases. The current manuscript sets up an agro-waste management platform by using paddy straw as a substrate for the production of nutritionally and medically rich oyster mushroom, Pleurotus florida (Pf) and which is further used in the green synthesis of bimetallic (gold-platinum) Au-Pt nanoparticle. Yield performance and biological efficiency of Pf were calculated from the degraded paddy straw. The green synthesized Au-Pt NPs were structurally characterized by ultraviolet-visible (UV-Vis), X-ray diffraction (XRD), transmission electron microscopy (TEM), energy dispersive spectroscopy (EDS), and zeta potential analysis. The prepared NPs showed a face-centered cubic crystal structure, icosahedral shape with a mean particle size of 16 nm. Furthermore, we examined the cytotoxic activity of Au-Pt NPs using 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyl tetrazolium bromide (MTT) assay, intracellular reactive oxygen species (ROS) generation, and apoptosis by propidium iodide assay. We found that Au-Pt NPs exerted apoptotic activity on the human colon cancer cell line (HCT 116) in a dose-dependent manner from 12.5 to 200 µg/mL. Overall, our findings create a prototype and open a new door to synthesizing functional nanoparticle by using oyster mushroom as the substrate for paddy straw agro-waste management and the applicability of Pf in the synthesis of eco-friendly Au-Pt NPs. This is the first kind of approach that kills two birds with one stone.

Mucuna pruriens in Parkinson's and in some other diseases: recent advancement and future prospective.

Mucuna pruriens (Mp) is an annual and perennial legume which belongs to the family Fabaceae having different types of therapeutic activity. Anti-oxidative, anti-inflammatory, anti-epileptic, anti-microbial, etc. are the example of some most common activities of Mp. It is widely utilized as a potent aphrodisiac. The anti-Parkinsonian activity of Mp was explored since the nineteenth century. The neuroprotective activity of Mp was shown by several researchers. Levodopa (L-DOPA) is the important constituents responsible for the anti-Parkinsonian activity of Mp. Apart from L-DOPA, several other important bioactive components like Ursolic acid (UA) and Betulinic acid (BA) also exhibit a similar neuroprotective activity. Parkinson's disease (PD) is mainly sporadic. A very small proportion shows the genetic nature of PD. The anti-Parkinsonian activity of Mp was explored in different toxin-induced PD models as like MPTP (1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine), Rotenone, Paraquat, 6-hydroxydopamine (6-OHDA) as suggested by several pieces of literature. Various parts of Mp's like seed, leaf, and stem exhibit potent neuroprotective attributes. Among different parts, seeds are widely utilized as anti-PD agents because of the higher percentage of L-DOPA. Besides anti-PD activity, Mp's neuroprotective potential was also explored in the ischemic model of stroke that also shows positive results. Recently, several clinical trials have been performed on the anti-PD activity of Mp on PD patients that show convincing results. Although, a small population-based study needs to be further validated in the broader population. Apart from anti-PD activity, Mp also shows its therapeutic activity in some other diseases like cancer, diabetes, skin infection, anemia, antihypertensive, etc. that are summarized in Table 1. In this review, we have discussed the anti-PD potential of Mp in the sporadic and genetic model along with some clinical trials that have performed on PD patients. Some other activity of Mp is also summarized in this review. There is a strong need to test the efficacy of Mp in some other neurodegenerative diseases along with PD. Following this, this review emphasizes the role of Mp in PD systematically through literature analysis available to date. [Table: see text].

Rapid eco-friendly synthesis, characterization, and cytotoxic study of trimetallic stable nanomedicine: A potential material for biomedical applications.

In the current scenario of the fight against cancer Integration of potential elements seems to be the best alternative since it overcomes the weaknesses of individuals and the combination of elements makes them formidable in the fight against the cancer war. Inspired by this objective and trusting our knowledge of paddy straw grown oyster mushroom, Pleurotus florida (Pf) mediated synthesis; a first-of-kind approach has been developed for the rapid synthesis of Au-Pt-Ag trimetallic nanoparticles (TMNPs). The developed method was successful, which was confirmed by Ultraviolet-Visible, X-ray diffraction, Transmission Electron Microscopy, Energy Dispersive Spectroscopy. Specifically, prepared TMNPs have been studied for their stability and size as a primary prerequisite for nanomedicine. Finally, the stable nanomedicine developed has been assessed for its performance against the highly metastatic breast cancer cell line (mda-mb-231). The performance was assessed using MTT assay and morphological readings, which were integrated with the cell viability data. We also determined the IC50 value, which was far superior to individual components and motivated us to postulate the possible breast cancer cell killing mechanism of TMNPs. The present study unlocks the new paths for the mushroom-mediated environmentally friendly, economic synthesis of trimetallic nanoparticles, which can be effectively used in cancer nanomedicine.

An overview of COVID-19 with an emphasis on computational approach for its preventive intervention.

SARS-CoV-2, a novel Betacoronavirus, has attracted global attention because of its extremely high infection rate and large number of human deaths. It possesses a positive-sense, single-stranded RNA of ~ 30 kb nucleotides as its genetic material. It is responsible for COVID-19 which has been declared a pandemic by WHO. Having reported for the first time in Wuhan, China, the virus infected over 21.48 million people and caused over 0.77 million deaths till mid-august 2020. SARS-CoV-2 contains the spike protein site that gets activated by an enzyme furin which is found in the lung, liver, and small intestine of humans. It shows the potentiality of virus for attacking multiple organs and their failures. Due to the absence of vaccines, the cure is restricted to supportive care including repurposed drugs. In silico approaches may offer an alternative screening to optimize hits to lead stages. It can provide important related to drug resistance, their lineages and evolution. This approach may also help to find an effective vaccine against COVID-19. This review focuses on the in silico aspects of genomics, proteomics, pathogenesis, phylogenetic analysis and viral receptor binding analysis in Betacoronavirus.
