Clinical and molecular epidemiology of enterovirus infections in cerebrospinal fluid samples, 2019-2023.

We performed a comparative, retrospective analysis (March 2019-April 2023) of children diagnosed with non-polio enterovirus (NPEV) central nervous system (CNS) infections (n = 47 vs. 129 contemporaneous controls without NPEV, all <18 years old), requiring cerebrospinal fluid (CSF) testing upon presentation to hospital. We found that showed that admissions decreased during pandemic restrictions (13% vs. controls 33%, p = 0.003). The median age of children with NPEV was 41 days (IQR: 18-72), most were male (n = 76, 59%) and were less likely to present with symptoms of irritability (11% vs. controls 26%, p = 0.04), but more likely to be febrile (93% vs. controls 73%, p = 0.007), have higher respiratory rates (mean 44 bpm, SD 11, vs. controls 36 bpm, SD 14, p = 0.001), higher heart rates (mean 171 bpm, SD 27 vs. controls 141 bpm, SD 36, p < 0.001), higher CSF protein (median 0.66 g/L, interquartile range [IQR] 0.46-1.01, vs. controls 0.53 mg/mL, IQR 0.28-0.89, p = 0.04), higher CSF white cell count (WCC) (median WCC 9.5×106/L, IQR 1-16 vs. controls 3.15×106/L, IQR 2.7-3.6, p < 0.001), but lower CSF glucose (median 2.8 mmol/L, IQR 2.4-3.1 vs. controls 3.1 mmol/L, IQR 2.7-3.6, p < 0.001). Phylogenetic analysis showed that these NPEVs originated from Europe (EV A71, CV B4, E21, E6, CV B3, CV B5, E7, E11, E18), North America (CV B4, E18), South America (E6), Middle East (CV B5), Africa (CV B5, E18), South Asia (E15), East/Southeast Asia (E25, CV A9, E7, E11, E18), and Australia (CV B5).

Torsemide in the Management of Pulmonary Edema.

Pulmonary edema, either cardiogenic or noncardiogenic, is caused by fluid accumulation in the alveolar spaces. Cardiogenic pulmonary edema (CPE), one of the causes of congestive heart failure (CHF), is treated with loop diuretics. Torsemide and furosemide were found to be useful in the treatment of CHF-associated pulmonary edema due to their ability to lower pulmonary capillary pressure and left ventricular end-diastolic pressure, respectively. Pharmacological features of torsemide, such as greater bioavailability, higher absorption rate, and efficacy, make it a better alternative for treating pulmonary edema than the regularly used loop diuretic, furosemide. Torsemide administered intravenously was found to be both efficacious and well tolerated in CPE. However, more research is needed to determine its usefulness in non-CPE.

Study of Tumor-Infiltrating Lymphocytes in Breast Carcinoma and Their Association With Pathological and Prognostic Factors and Pathological Tumor-Node-Metastasis (pTNM) Staging.

OBJECTIVES: Breast carcinoma is the second most frequent type of cancer globally, with an estimated 2.08 million new carcinoma cases identified in 2018. Breast cancer prognosis is influenced by a number of variables, including the patient's age, morphological variant, stromal inflammatory reaction, elastotic, fibrotic focus, lymphovascular emboli, recurrence of tumor, etc. Recently, the morphological evaluation and extent of tumor-infiltrating lymphocytes (TIL) have also been studied in breast cancer. An attempt is being made to understand the role of TIL in determining the prognostication of carcinoma breast. Thus, the goal of the current academic study is to assess TIL in breast carcinoma. MATERIALS AND METHOD: The study was performed at a medical institution's pathology department, which covered newly diagnosed cases of infiltrating ductal carcinoma of the breast on histopathology during the January to December 2019 time frame. The gross and hematoxyline-eosin-stained paraffin sections were studied for histopathological examination. RESULTS: The study included 50 cases of infiltrating ductal carcinoma of the breast with a female-to-male ratio of 24:1. Stromal TIL was negative (0-10%) in 12 cases, while was positive (11-100 %) in 38 cases. The results of the receiver operating characteristic (ROC) curve study indicated that the specificity was 70.7% and the sensitivity was 85.3% when the cutoff of stromal TIL <11% was used to predict the live status of patients. CONCLUSION: Stromal TIL is an important parameter that must be reported in breast carcinoma cases. Positive stromal TIL shows a statistically significant difference with pathological tumor-node-metastasis (pTNM) staging, tumor laterality, size of the tumor, and involvement of nipple and areola.

Health Data Sciences and Cardiovascular Diseases in South Asia: Innovations and Challenges in Digital Health.

PURPOSE OF REVIEW: Health data sciences can help mitigate high burden of cardiovascular disease (CVD) management in South Asia by increasing availability and affordability of healthcare services. This review explores the current landscape, challenges, and strategies for leveraging digital health technologies to improve CVD outcomes in the region. RECENT FINDINGS: Several South Asian countries are implementing national digital health strategies that aim to provide unique health account numbers for patients, creating longitudinal digital health records while others aim to digitize healthcare services and improve health outcomes. Significant challenges impede progress, including lack of interoperability, inadequate training of healthcare workers, cultural barriers, and data privacy concerns. Leveraging digital health for CVD management involves using big data for early detection, employing artificial intelligence for diagnostics, and integrating multiomics data for health insights. Addressing these challenges through policy frameworks, capacity building, and international cooperation is crucial for improving CVD outcomes in region.

A review: Current trends and future perspectives of bacterial nanocellulose-based wound dressings.

Bacterial cellulose (BC) has gained significant attention as a base material for wound dressings due to its superior physical properties, biocompatibility, and non-toxicity. However, to produce wound dressings that actively facilitate wound healing, BC modification is essential. To provide a comprehensive analysis of the potential research developments and the trends in bacterial cellulose-based wound dressings (BCWD), this review focuses on the BCWD research conducted in the last decade. The review highlights the optimization of BC usage as a base material for active wound dressing, including the incorporation of miscellaneous materials and the enhancement of BC properties such as ultra-transparency, anti-leakage, stretchability/flexibility, adhesiveness, conductivity, injectability, pattern, and pH-sensor ability.

Flavopiridol inhibits adipogenesis and improves metabolic homeostasis by ameliorating adipose tissue inflammation in a diet-induced obesity model.

Repositioning of FDA approved/clinical phase drugs has recently opened a new opportunity for rapid approval of drugs, as it shortens the overall process of drug discovery and development. In previous studies, we predicted the possibility of better activity profiles of flavopiridol, the FDA approved orphan drug with better fit value 2.79 using a common feature pharmacophore model for anti-adipogenic compounds (CFMPA). The present study aimed to investigate the effect of flavopiridol on adipocyte differentiation and to determine the underlying mechanism. Flavopiridol inhibited adipocyte differentiation in different cell models like 3T3-L1, C3H10T1/2, and hMSCs at 150 nM. Flavopiridol was around 135 times more potent than its parent molecule rohitukine. The effect was mediated through down-regulation of key transcription factors of adipogenesis i.e. Peroxisome proliferator-activated receptor gamma (PPARγ), CCAAT/enhancer-binding protein alpha (C/EBPα), and their downstream targets, including adipocyte protein -2 (aP2) and fatty acid synthase (FAS). Further, results revealed that flavopiridol arrested the cell cycle in G1/S phase during mitotic clonal expansion by suppressing cell cycle regulatory proteins i.e. Cyclins and CDKs. Flavopiridol inhibited insulin-stimulated signalling in the early phase of adipocyte differentiation by downregulation of AKT/mTOR pathway. In addition, flavopiridol improved mitochondrial function in terms of increased oxygen consumption rate (OCR) in mature adipocytes. In the mouse model of diet-induced obesity, flavopiridol attenuated obesity-associated adipose tissue inflammation and improved serum lipid profile, glucose tolerance as well as insulin sensitivity. In conclusion, the FDA approved drug flavopiridol could be placed as a potential drug candidate for the treatment of cancer and obesity comorbid patients.

A Mononuclear [PtCl(tpy)]PF6 Complex for a Yellow Emitting Solution-Processable Organic Light Emitting Diode.

We report square planar mononuclear Pt(II)-complexes of terpyridines in the form of [PtCl(L1/L2)]PF6 as phosphorescent emitters (where L1 = 4-(3-pyridine)2,2':6',2''-terpyridine and L2 = 4'-(3-pyridinyl)-4,4''-di(tert-butyl)-2,2':6'2''-terpyridine). Complex 2 showed emission at 534 nm in the DCM solution with photoluminescence quantum efficiency (ΦPL) = 14%, while in the mCBP host (5-wt % doped), the emission shifted to 584 nm with ΦPL = 37.8% and a phosphorescence lifetime (τphos) of 37.8 µs. Complex 2 in mCBP was used to fabricate a solution-processed phosphorescent organic light-emitting diode (PhOLED) which showed maximum external quantum efficiency (EQEmax) = 7.4% with yellow emission at λEL = 570 nm and exhibited a low efficiency roll-off with an EQE drop to 7.0% at 1000 cd/m2.

Unlocking the role of herbal cosmeceutical in anti-ageing and skin ageing associated diseases.

The process of skin ageing is a natural biological phenomenon characterised by the emergence of wrinkles, age spots, sagging skin, and dryness over time. The increasing significance of skin in physical attractiveness has heightened skincare concerns. Anti-ageing cosmetics play a pivotal role in nurturing the skin, enhancing its quality, and promoting overall health. Today, cosmetics have evolved beyond mere aesthetics and are now integral to individual wellness. The contemporary quest for perpetual youth has intensified, prompting a deeper exploration into the skin ageing process. This comprehensive exploration delves into various elements involved in skin ageing, encompassing cells such as stem and endothelial cells, blood vessels, soft tissues, and signalling pathways. The molecular basis of skin ageing, including biochemical factors like reactive oxygen species, damaged DNA, free radicals, ions, and proteins (mRNA), is scrutinised alongside relevant animal models. The article critically analyzes the outcomes of utilising herbal components, emphasising their advantageous anti-ageing properties. The factors contributing to skin ageing, mechanistic perspectives, management approaches involving herbal cosmeceutical, and associated complications (especially cardiovascular diseases, Parkinson's, Alzheimer's, etc.) are succinctly addressed. In addition, the manuscript further summarises the recent patented innovations and toxicity of the herbal cosmeceuticals for anti-ageing and ageing associated disorders. Despite progress, further research is imperative to unlock the full potential of herbal components as anti-ageing agents.

Food contamination from packaging material with special focus on the Bisphenol-A.

Additives, such as bisphenol A (BPA) that are added to packaging material to enhance functionality may migrate into food products creating a concern for food safety. BPA has been linked to various chronic diseases, such as: diabetes, obesity, prostate cancer, impaired thyroid function, and several other metabolic disorders. To safeguard consumers, BPA migration limits have been defined by regulatory bodies. However, it is important to address the underlying factors and mechanisms so that they can be optimized in order to minimize BPA migration. In this review, we determine the relative importance of the factors, i.e. temperature, contact time, pH, food composition, storage time and temperature, package type, cleaning, and aging, and packaging damage that promote BPA migration in foods. Packaging material seems to be the key source of BPA and the temperature (applied during food production, storage, can sterilization and cleaning processes) was the critical driver influencing BPA migration.

Benzofuran Iboga-Analogs Modulate Nociception and Inflammation in an Acute Mouse Pain Model.

Pain management following acute injury or post-operative procedures is highly necessary for proper recovery and quality of life. Opioids and non-steroidal anti-inflammatory drugs (NSAIDS) have been used for this purpose, but opioids cause addiction and withdrawal symptoms whereas NSAIDS have several systemic toxicities. Derivatives of the naturally occurring iboga alkaloids have previously shown promising behavior in anti-addiction of morphine by virtue of their interaction with opioid receptors. On this frontier, four benzofuran analogs of the iboga family have been synthesized and their analgesic effects have been studied in formalin induced acute pain model in male Swiss albino mice at 30 mg/kg of body weight dose administered intraperitoneally. The antioxidant, anti-inflammatory and neuro-modulatory effects of the analogs were analyzed. Reversal of tail flick latency, restricted locomotion and anxiogenic behavior were observed in iboga alcohol, primary amide and secondary amide. Local neuroinflammatory mediators' substance P, calcitonin gene related peptide, cyclooxygenase-2 and p65 were significantly decreased whereas the depletion of brain derived neurotrophic factor and glia derived neurotrophic factor was overturned on iboga analog treatment. Behavioral patterns after oral administration of the best analog were also analyzed. Taken together, these results show that the iboga family of alkaloid has huge potential in pain management.

Recent Progress on Synthesis of Functionalized 1,5-Disubstituted Triazoles.

Immediately after the invention of 'Click Chemistry' in 2002, the regioselective 1,2,3- triazole scaffolds resulted from respective organic azides and terminal alkynes under Cu(I) catalysis have been well recognized as the functional heterocyclic core at the centre of modern organic chemistry, medicinal chemistry, and material sciences. This CuAAC reaction has several notable features including excellent regioselectivity, high-to-excellent yields, easy to execute, short reaction time, modular in nature, mild condition, readily available starting materials, etc. Moreover, the resulting regioselective triazoles can serve as amide bond isosteres, a privileged functional group in drug discovery and development. More than hundreds of reviews had been devoted to the 'Click Chemistry' in special reference to 1,4-disubstituted triazoles, while only little efforts were made for an opposite regioisomer i.e., 1,5-disubstituted triazole. Herein, we have presented various classical approaches for an expeditious synthesis of a wide range of biologically relevant 1,5- disubstituted 1,2,3-triazole analogues. The syntheses of such a class of diversly functionalized triazoles have emerged as a crucial investigation in the domain of chemistry and biology. This tutorial review covers the literature assessment on the development of various synthetic protocols for the functionalized 1,5-disubstituted triazoles reported during the last 12 years.

On the Target Detection Performance of a Molecular Communication Network With Multiple Mobile Nanomachines.

A network of nanomachines (NMs) can be used to build a target detection system for a variety of promising applications. They have the potential to detect toxic chemicals, infectious bacteria, and biomarkers of dangerous diseases such as cancer within the human body. Many diseases and health disorders can be detected early and efficiently treated in the future by utilizing these systems. To fully grasp the potential of these systems, mathematical analysis is required. This paper describes an analytical framework for modeling and analyzing the performance of target detection systems composed of multiple mobile nanomachines of varying sizes with passive/absorbing boundaries. We consider both direct contact detection, in which NMs must physically contact the target to detect it, and indirect sensing, in which NMs must detect the marker molecules emitted by the target. The detection performance of such systems is calculated for degradable and non-degradable targets, as well as mobile and stationary targets. The derived expressions provide various insights, such as the effect of NM density and target degradation on detection probability.
