Metaverse for mental health disorders:Opportunities and challenges

Several articles on the mental health impact of the metaverse and the need to balance its potential benefits with the risks of metaverse use has recently published.The metaverse consists of a combination of immersive technologies and artificial intelligence algorithms.The metaverse differs from the preceding digital psychiatric interventions due to its complex structure and interactions between components.The diverse functions of the metaverse ensure that it may have a substantial impact on mental health.However,the evidence for its efficacy in treating mental health disorders is limited to a few trials.The mental health benefits of immersive technologies are well-documented and suggest that metaverse-based psychiatric treatment may be similarly efficacious.The mental health risks of the metaverse are largely unknown,and it is not clear whether they will be greater than other digital psychiatric interventions.Much more research is needed to determine whether metaverse-based psychiatric treatment will meet the standards of appropriate mental healthcare.

Biologics in the management of pediatric inflammatory bowel disease:When and what to choose

Pediatric inflammatory bowel disease(PIBD)is a chronic inflammatory disorder of the gastrointestinal tract,with rising global incidence and prevalence.Over the past two decades,biologics have added to the therapeutic armamentarium and revolutionized the approach to treatment of inflammatory bowel disease.The available biologics include monoclonal antibodies which target inflammatory cytokines(anti-tumor necrosis factor alpha,anti-interleukin 12/23)or recruitment of leucocytes to the gastrointestinal tract(anti-alpha4beta7 integrin)and small molecules(Janus kinase inhibitors,sphingosine 1-phosphate-inhibitors)which modify the proinflammatory signaling.Considering their potential disease-modifying ability,recent pediatric guidelines from the West have advocated upfront use of biologics in appropriate clinical scenarios as a top-down approach rather than the conventional step-up approach.Although real-world studies are available regarding the clinical efficacy of biologics in PIBD,there is paucity of long-term outcome and safety data in children.Also,little information is available about the best approach in the newly industrialized-developing countries where PIBD is rising but at the same time,infections are prevalent and resources are limited.In this review,we summarize the efficacy and safety profile of biologics and small molecule drugs and discuss the challenges in the management of PIBD,especially in the developing world,and future directions.

Congenital anomalies of coronary artery misdiagnosed as coronary dilatations in Kawasaki disease:A clinical predicament

BACKGROUND 2D-echocardiography(2DE)has been the primary imaging modality in children with Kawasaki disease(KD)to assess coronary arteries.AIM To report the presence and implications of incidental congenital coronary artery anomalies that had been misinterpreted as coronary artery abnormalities(CAAs)on 2DE.METHODS Records of children diagnosed with KD,who underwent computed tomography coronary angiography(CTCA)at our center between 2013-2023 were reviewed.We identified 3 children with congenital coronary artery anomalies in this cohort on CTCA.Findings of CTCA and 2DE were compared in these 3 children.RESULTS Of the 241 patients with KD who underwent CTCA,3(1.24%)had congenital coronary artery anomalies on CTCA detected incidentally.In all 3 patients,baseline 2DE had identified CAAs.CTCA was then performed for detailed evaluation as per our unit protocol.One(11-year-boy)amongst the 3 patients had complete KD,while the other two(3.3-year-boy;4-month-girl)had incomplete KD.CTCA revealed separate origins of left anterior descending artery and left circumflex from left sinus[misinterpreted as dilated left main coronary artery(LCA)on 2DE],single coronary artery(interpreted as dilated LCA on 2DE)and dilated right coronary artery on 2DE in case of anomalous origin of LCA from the main pulmonary artery.The latter one was subsequently operated upon.CONCLUSION CTCA is essential for detailed assessment of coronary arteries in children with KD especially in cases where there is suspicion of congenital coronary artery anomalies.Relying solely on 2DE may not be sufficient in such cases,and findings from CTCA can significantly impact therapeutic decision-making.

Endoscopic techniques for the diagnosis of pancreatic cystic lesions

Pancreatic cysts are mostly incidental findings on computed tomography or magnetic resonance imaging scans,with few patients presenting with abdominal pain or other symptoms.The accurate diagnosis of cysts is important as management depends on the type(neoplastic or non-neoplastic).Cross-sectional imaging is fast being replaced with endoscopic ultrasound(EUS)and various techniques based on that such as EUS-guided fine needle aspiration,EUS-guided needle confocal laser endomicroscopy,EUS-through-the-needle biopsy,and contrast-enhanced EUS.Clinical studies have reported varying diagnostic and adverse event rates with these modalities.In addition,American,European,and Kyoto guidelines for the diagnosis and management of pancreatic cysts have provided different recommendations.In this editorial,we elaborate on the clinical guidelines,recent studies,and comparison of different endoscopic methods for the diagnosis of pancreatic cysts.

Metabolic dysfunction-associated steatotic liver disease:A silent pandemic

The worldwide epidemiology of non-alcoholic fatty liver disease(NAFLD)is showing an upward trend,parallel to the rising trend of metabolic syndrome,owing to lifestyle changes.The pathogenesis of NAFLD has not been fully understood yet.Therefore,NAFLD has emerged as a public health concern in the field of hepatology and metabolisms worldwide.Recent changes in the nomenclature from NAFLD to metabolic dysfunction-associated steatotic liver disease have brought a positive outlook changes in the understanding of the disease process and doctor-patient communication.Lifestyle changes are the main treatment modality.Recently,clinical trial using drugs that target‘insulin resistance’which is the driving force behind NAFLD,have shown promising results.Further translational research is needed to better understand the underlying pathophysiological mechanism of NAFLD which may open newer avenues of therapeutic targets.The role of gut dysbiosis in etiopathogenesis and use of fecal microbiota modification in the treatment should be studied extensively.Prevention of this silent epidemic by spreading awareness and early intervention should be our priority.

Utilising continuous glucose monitoring for glycemic control in diabetic kidney disease

In this editorial,we comment on the article by Zhang et al.Chronic kidney disease(CKD)presents a significant challenge in managing glycemic control,especially in diabetic patients with diabetic kidney disease undergoing dialysis or kidney transplantation.Conventional markers like glycated haemoglobin(HbA1c)may not accurately reflect glycemic fluctuations in these populations due to factors such as anaemia and kidney dysfunction.This comprehensive review discusses the limitations of HbA1c and explores alternative methods,such as continuous glucose monitoring(CGM)in CKD patients.CGM emerges as a promising technology offering real-time or retrospective glucose concentration measure-ments and overcoming the limitations of HbA1c.Key studies demonstrate the utility of CGM in different CKD settings,including hemodialysis and peritoneal dialysis patients,as well as kidney transplant recipients.Despite challenges like sensor accuracy fluctuation,CGM proves valuable in monitoring glycemic trends and mitigating the risk of hypo-and hyperglycemia,to which CKD patients are prone.The review also addresses the limitations of CGM in CKD patients,emphasizing the need for further research to optimize its utilization in clinical practice.Altogether,this review advocates for integrating CGM into managing glycemia in CKD patients,highlighting its superiority over traditional markers and urging clinicians to consider CGM a valuable tool in their armamentarium.

Hepatic pseudotumor:A diagnostic challenge

Hepatic pseudotumors are rare lesions of unknown origin,characterized by the proliferation of fibrous connective tissue and inflammatory cell infiltrates.They mimic malignant lesions clinically,and radiologically,given their non-specific clinical and imaging features.The pathophysiology of hepatic pseudotumor is incompletely understood and there are no standardized criteria for diagnosis.Pseudotumors have been reported to develop in various organs in the body with the lung and liver being the most common site.Hepatic pseudotumors develop in patients with underlying triggers of liver inflammation and injury,including infections,autoimmune liver diseases,bile duct injury,or surgery.Hepatic pse-udotumors respond well to conservative treatment with antibiotics,and steroids and some may regress spontaneously,thus avoiding unnecessary resection.This condition is rewarding to treat.It is important to recognize pseudotumor as a distinct clinical entity and include it in the differential of liver masses with atypical imaging features.

Fecal microbiota transplantation in the treatment of hepatic encephalopathy:A perspective

Due to its complex pathogenesis,treatment of hepatic encephalopathy(HE)continues to be a therapeutic challenge.Of late,gut microbiome has garnered much attention for its role in the pathogenesis of various gastrointestinal and liver diseases and its potential therapeutic use.New evidence suggests that gut micro-biota plays a significant role in cerebral homeostasis.Alteration in the gut microbiota has been documented in patients with HE in a number of clinical and experimental studies.Research on gut dysbiosis in patients with HE has opened newer therapeutic avenues in the form of probiotics,prebiotics and the latest fecal microbiota transplantation(FMT).Recent studies have shown that FMT is safe and could be effective in improving outcomes in advanced liver disease patients presenting with HE.However,questions over the appropriate dose,duration and route of administration for best treatment outcome remains unsettled.

Digital psychiatry in low-and-middle-income countries:New developments and the way forward

Low-and middle-income countries(LMICs)bear the greater share of the global mental health burden but are ill-equipped to deal with it because of severe resource constraints leading to a large treatment gap.The remote provision of mental health services by digital means can effectively augment conventional services in LMICs to reduce the treatment gap.Digital psychiatry in LMICs has always lagged behind high-income countries,but there have been encouraging developments in the last decade.There is increasing research on the efficacy of digital psychiatric interventions.However,the evidence is not adequate to conclude that digital psychiatric interventions are invariably effective in LMICs.A striking development has been the rise in mobile and smartphone ownership in LMICs,which has driven the increasing use of mobile technologies to deliver mental health services.An innovative use of mobile technologies has been to optimize task-shifting,which involves delivering mental healthcare services in community settings using non-specialist health professionals.Emerging evidence from LMICs shows that it is possible to use digital tools to train non-specialist workers effectively and ensure that the psychosocial interventions they deliver are efficacious.Despite these promising developments,many barriers such as service costs,underdeveloped infrastructure,lack of trained professionals,and significant disparities in access to digital services impede the progress of digital psychiatry in LMICs.To overcome these barriers,digital psychiatric services in LMICs should address contextual factors influencing the delivery of digital services,ensure collaboration between different stakeholders,and focus on reducing the digital divide.

Understanding the role of transmembrane 9 superfamily member 1 in bladder cancer pathogenesis

In this editorial we comment on the article by Wei et al,published in the recent issue of the World Journal of Clinical Oncology.The authors investigated the role of Transmembrane 9 superfamily member 1(TM9SF1)protein in bladder cancer(BC)carcinogenesis.Lentiviral vectors were used to achieve silencing or overexpression of TM9SF1 gene in three BC cell lines.These cell lines were then subject to cell counting kit 8,wound-healing assay,transwell assay,and flow cytometry.Proliferation,migration,and invasion of BC cells were increased in cell lines subjected to TM9SF1 overexpression.TM9SF1 silencing inhibited proliferation,migration and invasion of BC cells.The authors conclude that TM9SF1 may be an oncogene in bladder cancer pathogenesis.

Endoscopic ultrasound-guided pancreatic fluid collection drainage: Where are we?

Pancreatic fluid collections(PFCs)result from injury to the pancreas from acute or chronic pancreatitis,surgery,or trauma.Management of these collections has evolved over the last 2 decades.The choice of interventions includes percu-taneous,endoscopic,minimally invasive surgery,or a combined approach.Endoscopic drainage is the drainage of PFCs by creating an artificial communication between the collection and gastrointestinal lumen that is maintained by placing a stent across the fistulous tract.In this editorial,we endeavored to update the current status of endoscopic ultrasound-guided drainage of PFCs.

Hindi translation and validation of the English version of the gastrointestinal symptom rating scale questionnaire:An observational study

BACKGROUND The gastrointestinal symptom rating scale(GSRS)is a questionnaire in English language which is designed to assess the clinical symptoms in patients with irritable bowel syndrome(IBS)and peptic ulcer disease.This validated scale has questions on around 15 items and has been validated in patients with dyspepsia and IBS.AIM To translate and validate the English version of the GSRS questionnaire to the Hindi version.METHODS The purpose of the present work was to create a Hindi version of this questionnaire for use in the Indian population.The process involved various steps as per the World Health Organization methodology including initial forward translation,backward translation,and assessment by an expert committee.Initial pilot testing was followed by testing in healthy and diseased individuals.RESULTS The Hindi translation was pilot tested in 20 individuals and further validated in healthy controls(n=30,15 females)and diseased individuals(n=72,27 females).The diseased group included patients with functional dyspepsia and IBS.Cronbach's alpha for internal consistency on the final translated GSRS questionnaire was 0.715 which is considered adequate.Twelve questions significantly differentiated the diseased population from the healthy population(P value<0.05)in the translated Hindi version of the GSRS.CONCLUSION The translated Hindi GSRS can be used to evaluate gastrointestinal function in clinical trials and community surveys in Hindi speaking populations.

Reference gene panel for urinary exosome-based molecular diagnostics in patients with kidney disease

BACKGROUND Kidney disease is a severe complication of diabetes that often leads to end-stage renal disease.Early diagnosis is crucial for prevention or delay.However,the current diagnostic methods,with their limitations in detecting the disease in its early stages,underscore the urgency and importance of finding new solutions.miRNAs encapsulated inside urinary exosomes(UEs)have potential as early biomarkers for kidney diseases.The need for reference miRNAs for accurate interpretation currently limits their translational potential.AIM To identify consistently expressing reference miRNAs from UEs of controls and patients with type 2 diabetesmellitus(T2DM)and biopsy-confirmed kidney diseases.METHODS miRNA profiling was performed on UEs from 31 human urine samples using a rigorous and unbiased method.The UEs were isolated from urine samples collected from healthy individuals(n=6),patients with T2DM(n=13),and T2DM patients who also had kidney diseases(including diabetic nephropathy,n=5;membranous nephropathy,n=5;and IgA nephropathy,n=2)through differential ultracentrifugation.After characterizing the UEs,miRNA expression profiling using microarray technology was conducted.RESULTS Microarray data analysis identified 14 miRNAs that were consistently expressed in UEs from 31 human samples,representing various kidney conditions:diabetic controls,diabetic nephropathy,membrane nephropathy,IgA nephropathy,and healthy controls.Through in silico analysis,we determined that 10 of these miRNAs had significant potential to serve as reference genes in UEs.CONCLUSION We identified uniformly expressing UE miRNAs that could serve as reference genes kidney disease biomarkers.

Malignant pleural mesothelioma:The disdained member of thoracic oncology!

Pleural mesothelioma is a very aggressive malignancy that arises from the pleural mesothelial cell lining and is linked strongly to prior asbestos exposure.The ban on asbestos has helped to lower the incidence,but in developing countries like India,it is expected to rise.It has an extended latency period usually progressing over decades and presents with nonspecific symptoms.It has a median survival ranging between 10-22 months.The diagnosis of malignant pleural mesothelioma is challenging and is done using computed tomography(CT),magnetic resonance imaging,or positron emission tomography-CT,with the last two predicting the resectability of the tumor better than CT alone.A pleural biopsy along with an array of immunohistochemical markers,such as p16,BRCA1 associated protein 1,and claudin-4,are required for a definitive diagnosis.Several genetic alterations have prognostic significance as well.The current histological subtype identification is indispensable for decision making because of the new therapeutic avenues being explored.The combination of nivolumab and ipilimumab-based immunotherapy outperformed platinum and pemetrexed-based chemotherapy in terms of survival benefit and improved quality of life especially for non-epithelioid subtypes.However,the latter continues to be a robust treatment option for patients with the epithelioid subtype.Surgery is recommended for resectable cases with radiotherapy being indicated in neoadjuvant,adjuvant,and palliative settings along with systemic treatment.This review article provides an overview of epidemiology,etiology,clinical manifestations,diagnostic approaches(including immunohistochemical and genetic markers),staging,and multidisciplinary approaches to current treatment for malignant pleural mesothelioma using surgery,chemotherapy,immunotherapy,and radiotherapy.It also sheds light on some recent studies(EMPHACIS,CALGB30901,Checkmate-743,etc.)that have led to significant developments in recent years with clinically meaningful results.

Parents’s knowledge and awareness about hepatitis B can influence the vaccination of their children

BACKGROUND Birth-dose(Hep-BD)followed by three additional doses(Hep-B3)of hepatitis B virus(HBV)vaccine are key to eliminating HBV by 2030.Unfortunately,Hep-BD and Hep-B3 coverage in our country is poor.AIM To studied the parent’s knowledge and awareness about HBV infection,its prevention,consequences and vaccination.METHODS Parents of 6 months to 8 years old children were interviewed to assess their knowledge&awareness about hepatitis B,its transmission,prevention,illness caused by this,and vaccination.Eighteen close-ended questions were admini-stered,and responses were recorded as‘yes’,‘no’,or‘not sure’.HBV knowledge score was calculated based on the sum of correct answers.Each correct response scored one point and incorrect,missing or‘not sure’responses received no points.Categorical data are presented as number(%)and numerical data are expressed as median.Data were compared using Chi2 tests and level of significance was kept as P<0.05.RESULTS Parents(58.3%mothers)of 384 children(89.9%age<5 years;82%age-appropriately vaccinated)were included.Three hundred and twenty-two(83.9%)children were Hep-B3 vaccinated.94.3%,87.5%,and 29.2%parents knew about polio,tetanus,and hepatitis B vaccine.Overall,41.2%,15.8%,and 23%parents knew about hepatitis B transmission,consequences of infection,and prevention respectively.Only 7.6%parents knew about three-dose schedule of hepatitis B vaccination.Only 23%parents believed that vaccine could prevent HBV,15.7%knew that HBV affects liver.Parents of Hep-B3 vaccinated children were significantly more aware about HBV than the parents of unvaccinated children(P<0.05 for 17/18 questions).CONCLUSION The knowledge and awareness among the parents about hepatitis B is poor.The Increasing knowledge/awareness about HBV among parents may improve Hep-B3 vaccination coverage.

Intravitreal therapy for the management of diabetic retinopathy:A concise review

Diabetic retinopathy(DR)is a serious microvascular complication of diabetes mellitus and may result in irreversible visual loss.Laser treatment has been the gold standard treatment for diabetic macular edema and proliferative diabetic retinopathy for many years.Of late,intravitreal therapy has emerged as a cornerstone in the management of DR.Among the diverse pharmacotherapeutic options,anti-vascular endothelial growth factor agents have demonstrated remarkable efficacy by attenuating neovascularization and reducing macular edema,thus preserving visual acuity in DR patients.

Geogenic Pollution of Groundwater Quality in Gampaha District, Sri Lanka: A Case Study of Groundwater Acidification from Rathupaswala

Over recent decades, Gampaha district, Sri Lanka, has experienced significant urbanisation and industrial growth, increasing groundwater demand due to limited and polluted surface water resources. In 2013, a community uprising in Rathupaswala, a village in Gampaha district, accused a latex glove manufacturing factory of causing groundwater acidity (pH < 4). This study evaluates the spatial and temporal changes in geochemical parameters across three transects in the southern part of Gampaha district to 1) assess the impact of geological formations on groundwater;2) compare temporal variations in groundwater;and 3) explain acidification via a geochemical model. Seventy-two sample locations were tested for pH, electrical conductivity (EC), and anion concentrations (sulphate, nitrate, chloride and fluoride). Depth to the water table and distance from the sea were measured to study variations across sandy, peaty, lateritic, and crystalline aquifers. Results showed pH readings around 7 for sandy and crystalline aquifers, below 7 for peaty aquifers, and below 5 for lateritic aquifers, with significant water table fluctuations near Rathupaswala area. Principal component analysis revealed three principal components (PCs) explaining 86.0% of the variance. PC1 (40.6%) correlated with pH, EC, and sulphate (saltwater intrusion), while PC2 (32.0%) correlated with nitrates and depth to the water table (anthropogenic nutrient pollution). A geochemical transport model indicated a cone of depression recharged by acidic groundwater from peat-soil aquifers, leading to acidic groundwater in Rathupaswala area. Previous attributions of acidic pH to the over-exploitation of groundwater by the latex factory have been reevaluated;the results suggest natural acidification from prolonged water-rock interactions with iron-rich lateritic aquifers. Groundwater pH is influenced by local climate, geology, topography, and drainage systems. It is recommended that similar water-rock interaction conditions may be present throughout the wet zone of Sri Lanka, warranting detailed studies to confirm this hypothesis.

Th1/Th2 cytokines and their genotypes as predictors of hepatitis B virus related hepatocellular carcinoma

Hepatocellular carcinoma(HCC), the predominant type of primary liver cancer, is one of the most serious lifethreatening malignancies, worldwide. In majority of the cases, HCC develops after prolonged and persistent chronic liver disease. hepatitis B virus(HBV) or HCV infection is prominent etiological factors, attributing to this condition. It has been well documented that HBV, being the inducer of chronic inflammation, is the main causative agent in causing HCC, particularly in Asian countries. The HBV infection leads to a wide range of clinical symptoms from carrier state to malignancy. Cytokines being immune-modulatory molecules, are the key mediators in the defense mechanism against viral infection. In this regard, this review will detail the substantial role of key Th1: interleukin 1(IL-1), IL-2, IL-12, tumor necrosis factor-α, interferon-γ; Th2: IL-4, IL-10 and non Th1/Th2: IL-6, transforming growth factor-β1 cytokines genotypes in analyzing the variability in the clinical manifestations in an HBV-afflicted individual, which might finally, culminates into HCC. Since cytokine production is regulated genetically, the cytokine promoter region single-nucleotide polymorphisms induced changes, greatly affects the cytokine production, thus resulting into differential outcome of immune balance.
