Abstract
Sickle cell disease (SCD) consists of a variety of hereditary hemoglobinopathies linked to alterations in the beta component of the hemoglobin (Hb) molecule. Acute SCD manifestations include stroke, acute chest syndrome (ACS), and pain, whereas chronic manifestations include avascular necrosis, chronic renal disease, and gallstones. This case report describes a rare instance of SCD-related pulmonary arterial hypertension (PAH) and cholelithiasis (CL). Following investigations, such as high-resolution CT scan thorax, chest X-ray, two-dimensional echocardiography, and ultrasonography of the abdomen and pelvis, PAH and CL were confirmed. The medical intervention mainly involved oxygenation, IV fluids, IV antibiotics, simple packed red blood cell transfusion (SBCT), folic acid, calcium supplementation, hydroxyurea, chest physiotherapy, and respiratory muscle strengthening exercises. The surgical intervention for CL was planned. Hence, the learning point from this case is that early multidisciplinary approach should be taken in order to control the progression of SCD.

Abstract
Endometrial receptivity is a complex and critical process fundamental to achieving a successful pregnancy. While researchers have made significant strides in understanding the underlying mechanisms governing endometrial receptivity, effective diagnostic and therapeutic strategies remain scarce. This review article aims to elucidate the various factors that contribute to endometrial receptivity, including the hormonal regulation and molecular mechanisms that govern this process, as well as potential biomarkers for assessing endometrial receptivity. One of the major challenges in identifying reliable biomarkers for endometrial receptivity is the intricate nature of the process itself. Nonetheless, recent advances in transcriptomic and proteomic technologies have identified several candidate biomarkers that could potentially enhance our ability to predict endometrial receptivity. Furthermore, emerging technologies such as single-cell RNA sequencing and mass spectrometry-based proteomics hold great promise for providing novel insights into the molecular mechanisms underlying endometrial receptivity. Despite the lack of reliable biomarkers, various therapeutic strategies have been proposed to improve endometrial receptivity. One promising approach involves the transplantation of mesenchymal stem cells (MSCs), which have been shown to increase endometrial thickness and receptivity in both animal models and clinical trials. Growth factors, cytokines, and exosomes derived from MSCs and other cell types may also have therapeutic potential for addressing endometrial dysfunction.

Abstract
Obestatin is a gut hormone composed of 23 amino acids that play a role in protecting the heart. It is synthesized from the same preproghrelin gut hormone gene as another gut hormone. The function and receptor of obestatin remain controversial, despite being present in various organs such as the liver, heart, mammary gland, pancreas, and more. The activity of obestatin is opposite to that of ghrelin, another hormone. The GPR-39 receptor is used by obestatin to exert its effects. Obestatin's cardioprotective role can be attributed to its ability to affect various factors, including adipose tissue, blood pressure regulation, heart, ischemia-reperfusion injury, endothelial cells, and diabetes. Because these factors are related to the cardiovascular system, modifying them via obestatin can provide cardioprotection. Furthermore, ghrelin, its antagonist hormone, regulates cardiovascular health. Diabetes mellitus, hypertension, and ischemia-reperfusion injury can all alter ghrelin/obestatin levels. Obestatin has also been shown to impact other organs, reducing weight and appetite, inhibiting food intake, and increasing adipogenesis. Obestatin has a brief half-life and is quickly degraded by proteases in the blood, liver, and kidneys after entering circulation. This article offers insights into the cardiac function of obestatin.

Abstract
The COVID-19 pandemic has had a devastating impact on a global scale, causing significant morbidity and mortality. The virus affects multiple organ systems, including the respiratory, cardiovascular, and coagulation systems, leading to severe pneumonia in some patients. Moreover, COVID-19 patients with severe pneumonia have a high incidence of thrombotic events, which can result in significant morbidity and mortality. Given the potential benefits of anticoagulation therapy in COVID-19 patients with thrombotic complications, recent studies have proposed high-dose prophylactic anticoagulation (HD-PA) therapy as a potential treatment option. In fact, some studies have suggested that HD-PA therapy may be more effective in reducing thrombotic events and mortality rates than other treatment options. This review aims to provide a comprehensive overview of the benefits and risks of HD-PA therapy for COVID-19 pneumonia patients. By synthesizing and analyzing the latest available research, we highlight patient selection criteria and discuss the optimal dosage, duration, and timing of therapy. Additionally, we review the potential risks associated with HD-PA therapy and provide recommendations for clinical practice. Ultimately, this review provides valuable insights into the use of HD-PA therapy in COVID-19 pneumonia patients and paves the way for further research in this critical area. By exploring the benefits and risks of this treatment option, we hope to provide healthcare professionals with the information they need to make informed decisions about the best course of treatment for their patients.

Abstract
Pesticide self-intoxication leading to suicide is a widespread phenomenon in India. Implementing regulations prohibiting the use of highly toxic pesticides in agriculture has proven effective in reducing the overall suicide rate in various South Asian countries without compromising agricultural production. In this study, we conducted a bibliometric analysis of scientific publications on pesticide poisoning in South Asian countries using various databases, including PubMed, Scopus, and Web of Science, using relevant Medical Subject Heading (MeSH) terms. To analyze the data, we employed R Studio and Microsoft Excel 2019, which enabled us to collect information on the number of scientific publications, citation frequency, and keyword trends. Our analysis involved 417 articles, and the results indicated a crucial need for greater awareness and improved management of pesticide poisoning in South Asian countries. Our findings provide valuable insights for policymakers and offer guidelines for pesticide control.

Abstract
Menopause is a physiological event in women's lives that typically transpires in midlife, denoting the cessation of ovarian function and ultimately leading to the end of reproductive capacity. However, women with schizophrenia-spectrum disorders may encounter unique challenges during this period because of the interaction between hormonal changes and their pre-existing mental health conditions. This literature review aims to investigate the consequences of menopause on women with schizophrenia-spectrum disorders, including modifications in symptomatology, cognitive function, and quality of life. Potential interventions will also be examined, including hormone replacement therapy and psychosocial support. The study findings suggest that menopause can worsen symptoms, such as hallucinations and delusions, and may also impair cognitive function, resulting in memory and executive function difficulties. Nevertheless, hormone replacement therapy and psychosocial support could offer potential avenues to manage symptoms and improve the quality of life for women with schizophrenia-spectrum disorders during menopause.

Abstract
Abstract
Aim
Consent is at the heart of the doctor-patient relationship. Valid consent should be voluntary, informed and the patient must have the capacity to make the decision. It is the doctor’s responsibility to ensure the patient can make an informed decision. The aim of this audit is to assess the validity of consent within Salford Royal Foundation Trust Orthopaedic department.
Method
We retrospectively reviewed 225 consent forms for four common orthopaedic trauma procedures: 44 wrist ORIF, 48 ankle fixation, 71 hip hemiarthroplasty and 62 fixations with DHS. BOA-endorsed OrthoConsent and SRFT-produced leaflets were utilised as a standard for reported surgical risks and complications. Collated patient consents were compared against these standards. Exclusion criteria included consent four and polytrauma patients.
Results
96 forms were excluded leaving 129 consent forms. In all four procedures, 86%-100% had documented infection, nerve injury and bleeding. Compartment syndrome was not documented for any wrist ORIF patients. CRPS was recorded in only 57% of wrist and 31% of ankle ORIF patients. Wound healing complications was documented in 17% of ankle ORIF. In 71% of DHS and 64% of hemiarthroplasty patients, risk of death was not recorded.
Conclusions
Targets for achieving satisfactory consent form documentation were not met and showed significant variation amongst clinicians. It suggests that patients are not being fully informed of benefits and risks of surgery. Recommendations include the introduction of posters and encouraging printing off patient information leaflets and improving education on valid consent for rotational doctors.

Abstract
Eukaryotic cells rely on multiple mechanisms to protect themselves from exogenous toxic compounds. For instance, cells can limit penetration of toxic molecules through the plasma membrane or sequester them within the specialized compartments. Plasma membrane transporters with broad substrate specificity confer multiple drug resistance (MDR) to cells. These transporters efflux toxic compounds at the cost of ATP hydrolysis (ABC-transporters) or proton influx (MFS-transporters). In our review, we discuss the possible costs of having an active drug-efflux system using yeast cells as an example. The pleiotropic drug resistance (PDR) subfamily ABC-transporters are known to constitutively hydrolyze ATP even without any substrate stimulation or transport across the membrane. Besides, some MDR-transporters have flippase activity allowing transport of lipids from inner to outer lipid layer of the plasma membrane. Thus, excessive activity of MDR-transporters can adversely affect plasma membrane properties. Moreover, broad substrate specificity of ABC-transporters also suggests the possibility of unintentional efflux of some natural metabolic intermediates from the cells. Furthermore, in some microorganisms, transport of quorum-sensing factors is mediated by MDR transporters; thus, overexpression of the transporters can also disturb cell-to-cell communications. As a result, under normal conditions, cells keep MDR-transporter genes repressed and activate them only upon exposure to stresses. We speculate that exploiting limitations of the drug-efflux system is a promising strategy to counteract MDR in pathogenic fungi.

Abstract
Cell-surface sphingomyelin (SM) inhibits binary and ternary complex activity of blood coagulation by an unknown mechanism. Here we show the OH functionality of SM contributes in forming the close assembly through intermolecular H-bond and through Ca2+ chelation, which restricts the protein–lipid/protein–protein interactions and thus inhibits the coagulation procedure. Cell-surface sphingomyelin (SM) inhibits binary and ternary complex activity of blood coagulation.![]()

Abstract
Deficiency in Sphingosine-1-phosphate lyase (S1P lyase) is associated with a multi-systemic disorder incorporating primary adrenal insufficiency (PAI), steroid resistant nephrotic syndrome and neurological dysfunction. Accumulation of sphingolipid intermediates, as seen with loss of function mutations in SGPL1, has been implicated in mitochondrial dysregulation, including alterations in mitochondrial membrane potentials and initiation of mitochondrial apoptosis. For the first time, we investigate the impact of S1P lyase deficiency on mitochondrial morphology and function using patient-derived human dermal fibroblasts and CRISPR engineered SGPL1-knockout HeLa cells. Reduced cortisol output in response to progesterone stimulation was observed in two patient dermal fibroblast cell lines. Mass spectrometric analysis of patient dermal fibroblasts revealed significantly elevated levels of sphingosine-1-phosphate, sphingosine, ceramide species and sphingomyelin when compared to control. Total mitochondrial volume was reduced in both S1P lyase deficient patient and HeLa cell lines. Mitochondrial dynamics and parameters of oxidative phosphorylation were altered when compared to matched controls, though differentially across the cell lines. Mitochondrial dysfunction may represent a major event in the pathogenesis of this disease, associated with severity of phenotype.

Abstract
Cisplatin is an effective anticancer drug used against a variety of cancers. The full therapeutic potential of cisplatin is often hampered due to concurrent development of various side effects in the hosts. Rutin, a naturally occurring bioflavonoid shows several pharmacological activities. It has been earlier reported by us that rutin and cisplatin in combination show better antitumor activity against murine ascites Dalton's lymphoma. As cisplatin is given to cancer-bearing hosts only, the present study was undertaken to explore the histoprotective effect of rutin against some toxicities induced by cisplatin in tumor-bearing mice. Cisplatin treatment caused severe damages in tissue architecture such as degenerated hepatocytes with nuclear condensation and sinusoidal dilatation in the liver, glomerular deterioration, infiltration of cells, and tubular congestion in the kidney, and vacuolization of Sertoli cells or dense granules in the cytoplasm and damaged seminiferous tubules in the testes. In the rutin plus cisplatin combination-treated mice, all the abnormal tissue architectural features were decreased. Further, as compared to cisplatin treatment, combination treatment did not show any significant elevation in the liver functional biomarkers (serum aspartate aminotransferase, alanine aminotransferase and alkaline phosphatase) and renal functional biomarkers (serum urea and creatinine levels). The combination treatment reduced the sperm abnormalities also as compared to the cisplatin alone treatment. The in vitro hemolysis assay of red blood cells and scanning electron microscopy revealed that combination treatment lessened the cisplatin-induced hemolysis and abnormalities in RBCs. Thus, the present findings demonstrate that rutin has histoprotective ability against cisplatin-induced toxicities in tumor-bearing mice.

Abstract
Background:Recent studies have demonstrated an increasing burden of musculoskeletal (MSK) diseases worldwide.1The importance of patient education (PE) is often overlooked in the management of long term inflammatory conditions. The European League Against Rheumatism recommends that PE should be integral to standard of care in inflammatory arthritis.2PE increases patients’ knowledge, skills and confidence in managing their condition and improves patient activation (PA). Evidence shows that improved PA results in better outcomes and improved experiences of care. We previously reported on improved knowledge and confidence amongst a small patient group with psoriatic arthritis (PsA) who had attended a pilot education session.3This education session was delivered to a wider group of patients with PsA over a 12 month period; we report on the evaluation received from this service.Objectives:To provide a PE programme to a wider group of patients with PsA, using a multi-disciplinary team (MDT) approach and to evaluate whether this improved patients’ knowledge, skills and confidence in managing their PsA.Methods:Adult patients with PsA attending their rheumatology clinic appointments were invited to a 2.5 hour MDT education session which covered: 1) a general overview of PsA; 2) medications used in PsA; 3) the role of physiotherapy and occupational therapy; 4) flares and self- management. These were interactive sessions, held in a small group setting to allow for informal discussion and questions to the MDT. Written materials including several booklets and online resources were also provided. Patients evaluated their knowledge or understanding before and after each topic covered, on the same day, using an evaluation tool with1-10 Likert scale items. Changes in ratings were analysed using student’s t-tests. Patients were also asked: which aspects they found particularly helpful; if there was anything they would like to have added/ have more of in the session; whether they found the session helpful; whether they would recommend it to other patients; whether they would be interested in developing a PsA patient support group.Results:Four sessions were held over a 12 month period. A total of 32 patients attended; 10 males and 22 females, across a range of age categories. Disease duration varied from less than1 year to over 10 years. There were statistically significant improvements in all topics covered: mean improvement of 91% in how well informed patients felt about PsA overall (p<0.0001); mean improvement of 74% in confidence in accessing help from the MDT (p<0.0001); mean improvement of 122% in how well informed patients were about medications used in PsA (p<0.0001); mean improvement of 99% in patients’ confidence in self-managing a flare (p<0.0001). Aspects that patients found particularly helpful included “The whole session”, “Asking questions to all different professionals”, “Meeting other sufferers”, “Management of flares”, “Fatigue information” and “Online resources”. Overall, 97% of patients (31 out of 32) found the session helpful and would recommend it to others. Over 40% of patients expressed interest in developing a local PsA support group.Conclusion:Following a 2.5 hour education session, improved knowledge, skills and confidence in managing their PsA was reported by 97% of patients, including patients with disease duration of > 10 years. This supports our previous finding that an interactive, group PsA education programme is a feasible and important adjunct to patient care.References:[1]Sebbag E, Felten R, Sagez F, et al.

Abstract
Supercapacitors (SCs) are used extensively in high-power potential energy applications like renewable energy systems, electric vehicles, power electronics, and many other industrial applications. This is due to SCs containing high-power density and the ability to respond spontaneously with fast charging and discharging demands. Advancements in material and fabrication techniques have induced a scope for research to improve the application of SCs. Many researchers have studied various SC properties and their effects on energy storage and management performance. In this paper, various fractional calculus-based SC models are summarized, with emphasis on analytical studies from derived classical SC models. Study prevails such parameterized resistor–capacitor networks have simplified the representation of electrical behavior of SCs to deal with the complicated internal structure. Fractional calculus has been used to develop SC models with the aim of understanding their complicated structure. Finally, the properties of different SC models utilized by various researchers to understand the behavior of SCs are listed using an equivalent circuit.

Abstract
BACKGROUND Cough is a common yet distressing symptom that results in significant health care costs from outpatient visits and related consultations. OBJECTIVE The understanding of the pathobiology of cough in recent times has undergone an evolution with Cough hypersensitivity syndrome (CHS) being suggested in most cases of dry cough. However, in the case of productive cough, ancillary mechanisms including impaired Mucociliary clearance, in addition to hypermucosecretory bronchospastic conditions of Smoker's cough, asthma-COPD overlap, bronchiectasis, and allergic bronchopulmonary aspergillosis, need to be critically addressed while optimizing patient care with symptomatic therapy in outpatient settings of India. METHODS In this review, evidence-based graded recommendations on use of antitussives - & protussives as a Position Paper were developed based on the Level and Quality of Scientific evidence as per Agency for Health Care and Quality (AHRQ) criteria listing and Expert opinions offered by a multidisciplinary EMA panel in India. RESULTS Management of acute or chronic cough involves addressing common issues of environmental exposures and patient concerns before instituting supportive therapy with antitussives or bronchodilatory cough formulations containing mucoactives, anti-inflammatory, or short-acting beta-2 agonist agents. CONCLUSION The analyses provides a real world approach to the management of acute or chronic cough in various clinical conditions with pro- or antitussive agents while avoiding their misuse in empirical settings.

BMC Health Serv Res 2019; 19:736. [PMID: 31640692 PMCID: PMC6805630 DOI: 10.1186/s12913-019-4606-z] [Citation(s) in RCA: 4] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/19/2018] [Accepted: 10/02/2019] [Indexed: 12/24/2022] Open
Abstract
BACKGROUND With about 50 million people infected with hepatitis B (HBV) in India the burden of disease is high. Stigma has been identified to have a major negative impact on screening, diagnosis and treatment of hepatitis B patients. The aim of this study was to assess the stigma in nurses and physicians in Bangalore, India; studies on stigma in HBV have only been published outside of India. METHODS Semi-structured in-depth-interviews were conducted in the period of March 20th and April 16th 2018 to study stigma and other problems in the care of hepatitis B patients. Stigma was pragmatically defined as a mark of disgrace associated with having a hepatitis B infection. Thirty physicians and nurses in different clinics and hospitals across the city of Bangalore were selected by purposeful sampling and snowball effect until theoretical saturation was reached. RESULTS The following themes were identified during the interviews: feelings when treating a patient; pregnancy and marriage; confidentiality; morality; improvement in care and the difference with HIV. The most stigma was discovered in the theme morality. The majority of our participants mentioned lack of awareness as biggest obstacle in health care of hepatitis B patients. CONCLUSIONS This is the first qualitative study in India exploring hepatitis B stigma among health care workers. Stigma was found in certain themes, such as morality. Though, no unwillingness to treat was found. There was a general lack of awareness amongst patients according to our participants and could jeopardize proper treatment. These results will further help in developing strategies to tackle hepatitis B in India.

Abstract
Mouse models of human diseases are an essential part of the translational pipeline. Orthotopic tumour mouse models are increasingly being used in cancer research due to their increased clinical relevance over subcutaneous xenograft models, particularly in relation to metastatic disease. In this study, we have developed orthotopic colorectal cancer liver metastases (CRCLM) and primary cholangiocarcinoma (CCA) models in BALB/c nude mice using minimally invasive ultrasound-guided intrahepatic injection. Due to its minimally invasive nature, the method reduced risk from surgical complications whilst being fast and easy to perform and resulted in measurable tumour volumes 1 to 3 weeks post-injection. Tumour volumes were monitored in vivo by weekly high-frequency ultrasound (HF-US) and/or twice weekly bioluminescence imaging (BLI) and confirmed with end-point histology. Take rates were high for human CRC cells (>73%) and for CCA cells (90%). We have demonstrated that this method reliably induces CRCLM and CCAs, in which tumour volume can be monitored throughout using HF-US and/or BLI. This provides a promising experimental tool for future testing of cancer therapeutics in an orthotopic model.
