    Abstract The purpose of the current investigation was to conduct a detailed analysis of the chemical components and medicinal properties of the methanolic crude extract derived from the leaves of Cassia fistula. This analysis was carried out using both experimental (in vivo) and computational (in silico) methods. Eleven chemicals were chromatographically isolated using GC-MS/MS, which utilizes a library of NIST and Wiley 2020 versions. FTIR analysis of the extract was performed to identify the functional group of the compounds. The glucose-lowering capacity, analgesic, and anti-diarrheal activities of methanolic crude extract were analyzed utilizing a well-known oral glucose tolerance test, tail immersion method, writhing assay, and castor oil-induced diarrheal mice methods, respectively. After 60 min, 120 min, and 180 min of loading the drugs, a significant reduction of blood glucose levels was examined (p < 0.05) in all the extracts of this plant (200 mg/kg, 400 mg/kg and 600 mg/kg) utilized in this research at a time-dependent manner. Similarly, all the crude extracts showed significant (p < 0.05) effects against pain centrally and peripherally compared to the standard drug morphine (2 mg/kg bw) and diclofenac sodium (50 mg/kg bw). Moreover, the methanol extract (400 mg/kg bw) manifested anti-diarrheal efficacy by inhibiting 72.0 % of the diarrheal episode in mice compared to the standard drug loperamide (inhibition = 80.0%). The results of the computational investigations corroborated existing in-vivo findings. Greater or close to equivalent binding affinity to the active binding sites of kappa opioid receptor, glucose transporter 3 (GLUT 3), and cyclooxygenase 2 was indicative of the potential anti-diarrheal, hypoglycemic, and analgesic characteristics of the isolated compounds (COX-2). Moreover, anticancer and antimicrobial potentiality was also found impressive through evaluation of binding affinity with epidermal growth factor receptor (EGFR) and dihydrofolate reductase (DHFR) receptors. Results from this study indicated that C. fistula might be a beneficial natural resource for treating diarrhea, hyperglycemia, and pain. However, additional research is required to conduct a comprehensive phytochemical screening and establish precise action mechanisms of the crude extract or the plant-derived compounds.

    Abstract Background: Work-life imbalance has been a growing issue globally particularly among healthcare workers including nurses as they must maintain a healthy work-life balance to deliver quality patient care-the primary objective of all healthcare organizations. Factors contributing to nurses' work-life imbalance have not been investigated well particularly in the Low-and-middle-income countries (LMIC) including Bangladesh. Aims: This study investigated the interrelationship of work-life imbalance, employee dissatisfaction, the impact of work on the family as well as the influence of family on work. Methods: This cross-sectional study was conducted among 656 nurses employed in various healthcare settings in Dhaka, Bangladesh using a convenient sampling technique. Face-to-face interviews were conducted between June 2 and December 15, 2022. Data were analyzed for descriptive and inferential statistics using STATA. This study adhered to Enhancing the Quality and Transparency of Health Research (EQUATOR) criteria. The probability of an event occurring and the correlations between predictive and outcome variables were determined using multivariate logistic regression. Results: Multinomial logistic regression revealed the highly influential parameters to work-life imbalance levels. The Pearson correlation showed the positive association between employees' unhappiness, family's negative impact on career, work's negative impact on family, and work-life imbalance. Conclusions: Maintaining nurses' work-life balance is critical in improving healthcare organizations' productivity, delivery of quality patient care and ensuring positive clinical outcomes.

    Abstract About 50% of the diabetic patients worldwide suffer from Diabetic peripheral neuropathy (DPN) which is characterized by chronic pain and loss of sensation, frequent foot ulcerations, and risk for amputation. Numerous factors like hyperglycemia, oxidative stress (OS), impaired glucose signaling, inflammatory responses, neuronal cell death are known to be the various mechanisms underlying DACD and DPN. Development of tolerance, insufficient and inadequate relief and potential toxicity of classical antinociceptives still remains a challenge in the clinical setting. Therefore, there is an emerging need for novel treatments which are both without any potential side effects as well as which focus more on the pathophysiological mechanisms underlying the disease. Also, sirtuins are known to deacetylate Nrf2 and contribute to its action of reducing ROS by generation of anti-oxidant enzymes. Therefore, targeting sirtuins could be a favourable therapeutic strategy to treat diabetic neuropathy by reducing ROS and thereby alleviating OS in DPN. In the present review, we outline the potential use of SIRT1 activators as therapeutic alternatives in treating DPN. We have tried to highlight how sirtuins are interlinked with Nrf2 and NF-κB and put forth how SIRT activators could serve as potential therapy for DPN.

    Abstract Behcet syndrome is a systemic vasculitic syndrome. Vascular involvement in Behcet syndrome affects both arterial and venous vascular systems, contributing to significant morbidity and mortality. However, diagnosing vascular lesions can be challenging due to their resemblance to common vascular diseases, leading to potential misdiagnoses. This case report emphasizes the importance of recognizing atypical manifestations of this disease to ensure a prompt and accurate diagnosis. This case report describes a unique presentation of Behcet syndrome in a 23-year-old male patient who presented with per rectal bleeding, abdominal distension, right quadrant abdominal pain, pleuritic chest pain, and fever. The patient also reported a history of recurrent oral and genital ulcers, skin lesions, and a previous episode of dural venous sinus thrombosis. Extensive investigations revealed the involvement of the inferior vena cava and right hepatic vein, representing an atypical vascular manifestation of Behcet syndrome. Prompt diagnosis by a multidisciplinary team led to appropriate treatment with cyclophosphamide and steroids, resulting in the resolution of vascular thrombosis. In this particular case, the patient presented with involvement of the inferior vena cava and right hepatic vein, a rare and unusual manifestation of the disease. This case highlights the diverse nature of vascular complications in Behcet syndrome and underscores the importance of considering this diagnosis in patients with unexplained vascular abnormalities. Overall, this case report highlights the importance of considering Behcet syndrome in the differential diagnosis of patients with unexplained vascular manifestations. It also emphasizes the need for a comprehensive clinical evaluation and collaborative approach to ensure timely and effective management.

    Abstract Background: The world faced a great health crisis during the COVID-19 pandemic. Consequently, the health care providers struggled and faced tremendous difficulties in treating high-load critical patients. This was particularly true in low- and middle-income countries where the work and patient loads are always higher and nurses at the forefront must deal with emergencies while being at high risk of exposure. However, little is known about the survival strategies of frontline nurses as dealt with the pandemic.
    Objectives: This study catalogued the coping strategies of frontline nurses to deal with caring for the COVID-19 patients during the pandemic.
    Methods: The Arksey O'Malley framework was followed to conduct a scoping review. A systematic literature search was conducted using three databases: Google Scholar, Scopus and PubMed; and out of the 192 studies, 12 met the inclusion criteria set for this review study.
    Results: A total of 44 strategies were identified that motivated nurses to deal with the COVID-19 situation, and these strategies could be categorized into five main themes: nurses' self-strategies, nurses' strategies at the ethical level, employers' strategies, nursing leaders' strategies and supplementary strategies.
    Conclusions: The findings of this study will provide guidance for health care workers, employers, policymakers, regulators and other stakeholders to adopt and promote different strategies in managing difficult emergency situations in future.
    Implications for nursing management: This study emphasizes the importance of learning how to deal with adversity by health care workers and organizations in an emergency.

    Abstract Altitude-related venous thrombosis (ARVT) is a condition of growing concern among individuals engaged in high-altitude travel and activities. This updated review explores the epidemiology, pathophysiological mechanisms, clinical presentations, and management of ARVT based on a thematic analysis and synthesis of the existing literature. ARVT's multifactorial etiology involves the interplay of hypobaric hypoxia and endothelial dysfunction, creating a procoagulant state and increasing the risk of thrombosis. Common clinical manifestations include pain, swelling, and redness in the extremities, necessitating accurate and timely diagnosis, particularly in remote settings. Thromboprophylaxis during high-altitude travel and activities plays a crucial role in reducing the risk of ARVT, while anticoagulation remains the mainstay of management. Further research is needed to optimize preventive and treatment strategies, enhancing patient outcomes and safety in high-altitude environments.
