Abstract
Introduction Diagnosis of wall-thickening type gallbladder cancer (GBC) is challenging. Computed tomography (CT) and magnetic resonance imaging (MRI) are commonly utilized to evaluate gallbladder wall thickening. However, there is a lack of data comparing the performance of CT and MRI for the detection of wall-thickening type GBC. Aim We aim to compare the diagnostic accuracy of CT and MRI in diagnosis of wall-thickening type GBC. Materials and methods This prospective study comprised consecutive patients suspected of wall-thickening type GBC who underwent preoperative contrast-enhanced CT and MRI. The final diagnosis was based on the histopathology of the resected gallbladder lesion. Two radiologists independently reviewed the characteristics of gallbladder wall thickening at CT and MRI. The association of CT and MRI findings with histological diagnosis and the interobserver agreement of CT and MRI findings were assessed. Results Thirty-three patients (malignancy, 13 and benign, 20) were included. None of the CT findings were significantly associated with GBC. However, at MRI, heterogeneous enhancement, indistinct interface with the liver, and diffusion restriction were significantly associated with malignancy (P = 0.006, <0.001, and 0.005, respectively), and intramural cysts were significantly associated with benign lesions (P = 0.012). For all MRI findings, the interobserver agreement was substantial to perfect (kappa = 0.697-1.000). At CT, the interobserver agreement was substantial to perfect (k = 0.631-1.000). Conclusion These findings suggest that MRI may be preferred over CT in patients with suspected wall thickening type GBC. However, larger multicenter studies must confirm our findings.

Abstract
Background Biliary obstruction in gallbladder cancer (GBC) is associated with worse prognosis and needs drainage. In patients with biliary confluence involvement, percutaneous biliary drainage (PBD) is preferred over endoscopic drainage. However, PBD catheters are associated with higher complications compared to endoscopic drainage. PBD with self-expandable metal stents (SEMS) is desirable for palliation. However, the data in patients with unresectable GBC is lacking. Materials and methods This retrospective study comprised consecutive patients with proven GBC who underwent PBD-SEMS insertion between January 2021 and December 2022. Technical success, post-procedural complications, clinical success, duration of stent patency, and biliary reinterventions were recorded. Clinical follow-up data was analysed at 30 days and 180 days of SEMS insertion and mortality was recorded. Results Of the 416 patients with unresectable GBC, who underwent PBD, 28 (median age, 50 years; 16 females) with PBD-SEMS insertion were included. All SEMS placement procedures were technically successful. There were no immediate/early post-procedural complications/deaths. The procedures were clinically successful in 63.6% of the patients with hyperbilirubinemia (n = 11). Biliary re-interventions were done in 6 (21.4%). The survival rate was 89.3 % (25/28) at 30 days and 50% at 180 days. The median follow-up duration was 80 days (range, 8-438 days). Conclusion PBD-SEMS has moderate clinical success and 6-months patency in almost half of the patients with metastatic GBC and must be considered for palliation.

Abstract
BACKGROUND Ferrum phosphoricum (FP) has been used by traditional medicine practitioners for various ailments since ancient times. However, scientific evidence on the safety of FP is still unavailable. Thus, the current study aimed to investigate the acute and sub-acute oral toxicity of homeopathic FP in experimental rats. METHODS In an acute toxicity investigation, a single dose of 2,000 µL/kg of FP 6c, 30c and 200c was administered to female Wistar rats, which were monitored for up to 14 days according to the Organization for Economic Cooperation and Development (OECD) guideline 423. For a sub-acute toxicity study, FP 6c, 30c and 200c (200 µL/kg) were administered to male and female rats for 28 days as per the OECD guideline 407. All the animals were observed for mortality, clinical signs and body weight during the study. At the end of the experiment, hematological, biochemical and histopathological assessments were performed. RESULTS During the acute toxicity study, no mortality was observed in rats administered with FP, and thus the median lethal dose (LD50) was identified as >2,000 µL/kg. In the sub-acute study, no mortality or adverse clinical signs were noticed with FP treatment. Moreover, weekly body weight gain was normal. Hematological and biochemical investigations revealed no abnormalities. Furthermore, histological analysis of FP-treated rats' vital organs revealed no pathological changes. CONCLUSION Overall, our findings imply that FP 6c, 30c and 200c potencies are safe and do not cause toxicity when given orally to Wistar albino rats for an extended period at a dose of 200 µL/kg.

Abstract
58S bioactive glass (BG) has effective biocompatibility and bioresorbable properties for bone tissue engineering; however, it has limitations regarding antibacterial, antioxidant, and mechanical properties. Therefore, we have developed BGAC biocomposites by reinforcing 58S BG with silver and ceria nanoparticles, which showed effective bactericidal properties by forming inhibited zones of 2.13 mm (against Escherichia coli) and 1.96 mm (against Staphylococcus aureus; evidenced by disc diffusion assay) and an increment in the antioxidant properties by 39.9%. Moreover, the elastic modulus, hardness, and fracture toughness were observed to be increased by ∼84.7% (∼51.9 GPa), ∼54.5% (∼3.4 GPa), and ∼160% (∼1.3 MPam1/2), whereas the specific wear rate was decreased by ∼55.2% (∼1.9 × 10-11 m3/Nm). X-ray diffraction, high-resolution transmission electron microscopy, and field emission scanning electron microscopy confirmed the fabrication of biocomposites and the uniform distribution of the nanomaterials in the BG matrix. The addition of silver nanoparticles in the 58S BG matrix (in BGA) increased mechanical properties by composite strengthening and bactericidal properties by damaging the cytoplasmic membrane of bacterial cells. The addition of nanoceria in 58S BG (BGC) increased the antioxidant properties by 44.5% (as evidenced by the 2,2-diphenyl-1-picrylhydrazyl assay). The resazurin reduction assay and MTT assay confirmed the effective cytocompatibility for BGAC biocomposites against mouse embryonic fibroblast cells (NIH3T3) and mouse bone marrow stromal cells. Overall, BGAC resulted in mechanical properties comparable to those of cancellous bone, and its effective antibacterial and cytocompatibility properties make it a good candidate for bone healing.

Abstract
PURPOSE To study the ophthalmologic manifestations of systemic sclerosis (SSc) and its correlation with autoantibody profile. METHODS A cross-sectional study on 200 eyes of 100 consecutive adult patients diagnosed with SSc was performed at a tertiary care center in Northern India. The examination of ocular adnexa, anterior segment, and posterior segment with slit-lamp biomicroscopy, tear film break-up time (TBUT), Schirmer's II test, and choroidal thickness measurement by swept-source ocular coherence tomography was done. Autoantibody profile was available for 85 patients, and its statistical association with the ocular examination findings was analyzed. RESULTS In total, 100 patients (93 females and 7 males) were included. The mean age was 45.11 ± 11.68 years, and the mean disease duration was 6.93 ± 3.68 years. Meibomian gland disease was more commonly found in patients with the diffuse subtype of SSc (P = 0.037). Choroidal thickness was increased in 34% and decreased in 7% (reference range = 307 ± 79 mm) patients. Reduced TBUT, meibomian gland dysfunction, and eyelid stiffness had a statistically significant association with the presence of anti-Scl-70 antibody (P = 0.003, <0.0001, and 0.004, respectively). These patients had ocular fatigue, foreign body sensation, and burning sensation. No significant association was noted with the presence of SS-A/Ro and SS-B/La antibodies. CONCLUSION This study highlights the need for an active comprehensive ophthalmic evaluation. Approximately 75% of the patients in our cohort had ocular involvement to varying extent. An isolated presence of anti-Scl70 antibody was also found to have a positive association with dry eye disease.

Abstract
Acute pancreatitis is an acute inflammatory condition of the pancreas that has not only local but systemic effects as well. Venous thrombosis is one such complication which can give rise to thrombosis of the peripheral vasculature in the form of deep vein thrombosis, pulmonary embolism, and splanchnic vein thrombosis. The prevalence of these complications increases with the severity of the disease and adds to the adverse outcomes profile. With better imaging and awareness, more cases are being detected, although many at times it can be an incidental finding. However, it remains understudied and strangely, most of the guidelines on the management of acute pancreatitis are silent on this aspect. This review offers an overview of the incidence, pathophysiology, symptomatology, diagnostic work-up, and management of venous thrombosis that develops in AP.

Abstract
Hepatocellular carcinoma (HCC) is one of the most common primary malignancies of the liver and a leading cause for cancer-related deaths worldwide. HCC surveillance aims at early detection. The recommended strategy for screening HCC is biannual ultrasound with or without alpha-fetoprotein. However, this strategy is associated with sub-optimal sensitivity. Abbreviated magnetic resonance imaging (AMRI) is a promising alternative to ultrasound (US) for surveillance of HCC. The data regarding the role of AMRI in HCC screening is evolving. There are different AMRI protocols, each having its merits and disadvantages. In this review, we discuss the need for AMRI, protocols of AMRI and hindrances to widespread adoption of AMRI.

Abstract
OBJECTIVE To describe the radiopathological characteristics of a new morphological "combined type" of gallbladder cancer (GBC) and compare it with the mass replacing gallbladder and thickening types of GBC. MATERIALS AND METHODS The imaging and pathological details of consecutive patients with GBC between August 2020 and December 2022 were retrospectively reviewed. Two radiologists reviewed computed tomography/magnetic resonance imaging in consensus for the morphological type of GBC. The radiologists classified GBC as mass replacing gallbladder, wall thickening, and combined type. The combined type was defined as a mass arising from the thickened wall of an adequately distended gallbladder that extended exophytically into the adjacent liver parenchyma. The presence of calculi, site, and size of lesion, biliary/portal vein involvement, liver, lymph node, and omental metastases was compared among the various types. The pathological characteristics were also compared. RESULTS Of the 481 patients (median age 55 years, 63.2% females) included in the study, mass replacing gallbladder, wall thickening, and combined-type GBC were seen in 42.8% (206/481), 40.5% (195/481), and 16.6% (80/481) of patients, respectively. In the combined type of GBC, biliary/portal vein involvement was seen in 63.7% (51/80) and 7.5% (6/80) of patients. Liver, lymph node, and omental metastases were seen in 67.5% (54/80), 40% (32/80), and 41.2% (33/80) patients, respectively. Liver metastases were significantly more common in the combined type (p = 0.002). There were no significant differences in pathological characteristics among the various types. CONCLUSION Combined-type GBC is less common than the mass replacing gallbladder and thickening types and is associated with a higher risk of liver metastases.

Abstract
Biliary tract cancers are malignant neoplasms arising from bile duct epithelial cells. They include cholangiocarcinomas and gallbladder cancer. Gallbladder cancer has a marked geographical preference and is one of the most common cancers in women in northern India. Biliary tract cancers are usually diagnosed at an advanced, unresectable stage. Hence, the prognosis is extremely dismal. The five-year survival rate in advanced gallbladder cancer is < 5%. Hence, early detection and radical surgery are critical to improving biliary tract cancer prognoses. Radiological imaging plays an essential role in diagnosing and managing biliary tract cancers. However, the diagnosis is challenging because the biliary tract is affected by many diseases that may have radiological appearances similar to cancer. Artificial intelligence (AI) can improve radiologists' performance in various tasks. Deep learning (DL)-based approaches are increasingly incorporated into medical imaging to improve diagnostic performance. This paper reviews the AI-based strategies in biliary tract cancers to improve the diagnosis and prognosis.

Abstract
BACKGROUND Although both nonsteroidal anti-inflammatory drugs (NSAIDs) and opioids are used for analgesia in acute pancreatitis (AP), the analgesic of choice is not known. We compared buprenorphine, an opioid, and diclofenac, an NSAID, for analgesia in AP. METHODS In a double-blind randomized controlled trial, AP patients were randomized to receive intravenous diclofenac or intravenous buprenorphine. Fentanyl was used as rescue analgesia, delivered through a patient-controlled analgesia pump. Primary outcome was the difference in the dose of rescue fentanyl required. Secondary outcomes were the number of effective and ineffective demands of rescue fentanyl, pain-free interval, reduction in visual analogue scale (VAS) score, adverse events, and organ failure development. RESULTS Twenty-four patients were randomized to diclofenac and 24 to buprenorphine. The 2 groups were matched at baseline. The total amount of rescue fentanyl required was significantly lower in the buprenorphine group:130 μg, interquartile range (IQR), 80-255 vs 520 μg, IQR, 380-1065 (P < .001). The number of total demands was 32 (IQR, 21-69) in the diclofenac arm vs 8 (IQR, 4-15) in the buprenorphine arm (P < .001). The buprenorphine group had more prolonged pain-free interval (20 vs 4 hours; P < .001), with greater reduction in the VAS score at 24, 48, and 72 hours compared with the diclofenac group. These findings were confirmed in the subgroup of moderately severe/severe pancreatitis. Adverse events profile was similar in the 2 groups. CONCLUSIONS Compared with diclofenac, buprenorphine appears to be more effective and equally safe for pain management in AP patients, even in the subcohort of moderately severe or severe pancreatitis (Trial Registration number: CTRI/2020/07/026914).

Abstract
BACKGROUND AND AIM Discrimination of gastrointestinal tuberculosis (GITB) and Crohn's disease (CD) is difficult. Use of artificial intelligence (AI)-based technologies may help in discriminating these two entities. METHODS We conducted a systematic review on the use of AI for discrimination of GITB and CD. Electronic databases (PubMed and Embase) were searched on June 6, 2022, to identify relevant studies. We included any study reporting the use of clinical, endoscopic, and radiological information (textual or images) to discriminate GITB and CD using any AI technique. Quality of studies was assessed with MI-CLAIM checklist. RESULTS Out of 27 identified results, a total of 9 studies were included. All studies used retrospective databases. There were five studies of only endoscopy-based AI, one of radiology-based AI, and three of multiparameter-based AI. The AI models performed fairly well with high accuracy ranging from 69.6-100%. Text-based convolutional neural network was used in three studies and Classification and regression tree analysis used in two studies. Interestingly, irrespective of the AI method used, the performance of discriminating GITB and CD did not match in discriminating from other diseases (in studies where a third disease was also considered). CONCLUSION The use of AI in differentiating GITB and CD seem to have acceptable accuracy but there were no direct comparisons with traditional multiparameter models. The use of multiple parameter-based AI models have the potential for further exploration in search of an ideal tool and improve on the accuracy of traditional models.

Abstract
Autoimmune gastrointestinal (GI) disorders comprise a heterogeneous group of diseases with non-specific clinical manifestations. These are divided into primary and secondary. A high index of clinical suspicion complemented with endoscopic and radiological imaging may allow early diagnosis. Due to the relatively low incidence of autoimmune disorder, the imaging literature is sparse. In this review, we outline the pathogenesis, classification, and imaging appearances of autoimmune GI disorders.

Abstract
Introduction Peripheral nerve injuries (PNIs) remain an important health problem. PNIs mostly affect young men as this age group is mostly involved in road traffic accidents and other injuries at workplace. PNI can occur from foreign bodies like metal chips while working in industries using lathe machines. Among PNI's, injuries to the ulnar nerve, the brachial plexus and the median nerve are the most frequent lesions encountered. Materials and methods This presentation is on a series of 18 cases of nerve injuries among industrial workers located from finger level up to the arm excluding the brachial plexus due to metallic foreign bodies entering while operating lathe machines over a period of two years with patients being followed-up over a one year period. Results Mean age in this series was 31.3 years with age range 16-40 years and all were males. Two patients had more than one nerve involvement and one patient had associated vascular injury. All the patients showed functional improvement. Most common nerve injured was median nerve. Most common site for nerve injury was forearm. Combined lesions most commonly involved the ulnar and median nerves. Conclusion Social cost of traumatic peripheral nerve injuries is significant since it has a higher incidence in young, previously healthy, and economically active people.

Abstract
BACKGROUND Fermented formulations are extensively used in Ayurveda due to several benefits like improved palatability, bioavailability, pharmacological potential, and shelf life. These formulations can also quench the heavy metals from the plant material and thus reduce the toxicity. Seeds of Silybum marianum (L.) Gaertn. are widely used for the management of many liver diseases. STUDY DESIGN AND METHODS In the present study, we developed a novel fermented formulation of S. marianum seeds and evaluated parameters like safety (heavy metal analysis) and effectiveness (hepatoprotective). As the developed formulation's validation is crucial, the critical process variables (time, pH, and sugar concentration) are optimized for alcohol and silybin content using the Box-Behnken design (BBD). RESULTS The response surface methodology coupled with BBD predicted the optimized conditions (fermentation time (28 days), pH 5.6, and sugar concentration (22.04%)) for the development of a fermented formulation of the selected herb. Moreover, the alcohol content (6.5 ± 0.9%) and silybin concentration (26.1 ± 2.1%) were confirmed in optimized formulation by GC-MS and HPTLC analysis. The optimized formulation was also analyzed for heavy metals (Pb, As, Hg, and Cd); their concentration is significantly less than the decoction of herbs. Further, the comparative evaluation of the developed formulation with the marketed formulation also confirmed that the fermented formulation's silybin concentration and percentage release were significantly enhanced. In addition, the developed fermented formulation's percentage recovery of HepG2 cell lines after treatment with CCl4 was significantly improved compared with the marketed formulation. CONCLUSION It can be summarized that the developed fermented formulation improves safety and effectiveness compared to other market formulations. Finally, it can be concluded that the developed fermented formulation could be further explored as a better alternative for developing Silybum marianum preparation.

Abstract
Pancreatic fistula is a highly morbid complication of pancreatitis. External pancreatic fistulas result when pancreatic secretions leak externally into the percutaneous drains or external wound (following surgery) due to the communication of the peripancreatic collection with the main pancreatic duct (MPD). Internal pancreatic fistulas include communication of the pancreatic duct (directly or via intervening collection) with the pleura, pericardium, mediastinum, peritoneal cavity, or gastrointestinal tract. Cross-sectional imaging plays an essential role in the management of pancreatic fistulas. With the help of multiplanar imaging, fistulous tracts can be delineated clearly. Thin computed tomography sections and magnetic resonance cholangiopancreatography images may demonstrate the communication between MPD and pancreatic fluid collections or body cavities. Endoscopic retrograde cholangiography (ERCP) is diagnostic as well as therapeutic. In this review, we discuss the imaging diagnosis and management of various types of pancreatic fistulas with the aim to sensitize radiologists to timely diagnosis of this critical complication of pancreatitis.

Abstract
INTRODUCTION U.S. veterans in the Veterans Affairs (VA) Healthcare System are managed in a national single-payer system with access to FDA-approved therapies. Prescribing patterns and outcomes of patients with CLL manage in the VA system are described. PATIENTS AND METHODS This is a retrospective analysis of adult patients diagnosed with CLL managed in the VA from January 1999 through December 2020. First line treatment patterns are trended over 20 years. Factors associated with survival were analyzed in both untreated and treated patients. RESULTS In the final analysis, 16,331 patients with CLL were included. The median overall survival (OS) for the whole cohort was 8.7 years (95% confidence interval [CI], 8.6-8.9). The median OS from diagnosis was 8.9 years (95% CI, 8.6-9.2 in untreated patients with CLL. In treated patients, the median time to first line treatment was 1.9 years (range, 0-21 years), and the median OS from initiation of treatment was 5.0 years (95% CI, 4.8-5.2). First line treatments varied over time, consistent with FDA approval of targeted therapies. Exposure to targeted therapies as either first line or in subsequent lines of therapy was associated longer survival: median OS of 8.5 years (95% CI, 8.0-9.1) compared to 3.5 years (95% CI, 3.5-3.9) in patients who never received targeted therapy (P < .0001). CONCLUSION Patients treated in the VA have received therapies in line with current evidence-based treatment practices over the past 20 years. Treatment with targeted therapies is associated with longer median OS both in the first line and relapsed/refractory setting.

Abstract
OBJECTIVES Many reverse transcription polymerase chain reaction (RT-PCR) methods exist that can detect SARS-CoV-2 RNA in different matrices. RT-PCR is highly sensitive, although viral RNA may be detected long after active infection has taken place. SARS-CoV-2 proteins have shorter detection windows hence their detection might be more meaningful. Given salivary droplets represent a main source of transmission, we explored the detection of viral RNA and protein using four different detection platforms including SISCAPA peptide immunoaffinity liquid chromatography-mass spectrometry (SISCAPA-LC-MS) using polyclonal capture antibodies. METHODS The SISCAPA-LC MS method was compared to RT-PCR, RT-loop-mediated isothermal amplification (RT-LAMP), and a lateral flow rapid antigen test (RAT) for the detection of virus material in the drool saliva of 102 patients hospitalised after infection with SARS-CoV-2. Cycle thresholds (Ct) of RT-PCR (E gene) were compared to RT-LAMP time-to-positive (TTP) (NE and Orf1a genes), RAT optical densitometry measurements (test line/control line ratio) and to SISCAPA-LC-MS for measurements of viral protein. RESULTS SISCAPA-LC-MS showed low sensitivity (37.7 %) but high specificity (89.8 %). RAT showed lower sensitivity (24.5 %) and high specificity (100 %). RT-LAMP had high sensitivity (83.0 %) and specificity (100.0 %). At high initial viral RNA loads (<20 Ct), results obtained using SISCAPA-LC-MS correlated with RT-PCR (R2 0.57, p-value 0.002). CONCLUSIONS Detection of SARS-CoV-2 nucleoprotein in saliva was less frequent than the detection of viral RNA. The SISCAPA-LC-MS method allowed processing of multiple samples in <150 min and was scalable, enabling high throughput.

Abstract
Background/Aims Association of sarcopenia with disease severity in ulcerative colitis (UC) is not clearly defined. We planned to estimate the prevalence of sarcopenia in patients with UC as per the revised definition and its relation with the disease severity. Methods A cross-sectional assessment of sarcopenia in patients with UC was performed. Disease activity was graded according to complete Mayo score. Hand grip strength was assessed with Jamar hand dynamometer, muscle mass using a dual energy X-ray absorptiometry scan, and physical performance with 4-m walk test. Sarcopenia was defined as a reduction of both muscle mass and strength. Severe sarcopenia was defined as reduced gait speed in presence of sarcopenia. Results Of 114 patients (62 males, mean age: 36.49±12.41 years), 32 (28%) were in remission, 46 (40.4%) had mild-moderate activity, and 36 (31.6%) had severe UC. Forty-three patients (37.7%) had probable sarcopenia, 25 (21.9%) had sarcopenia, and 14 (12.2%) had severe sarcopenia. Prevalence of sarcopenia was higher in active disease (2 in remission, 6 in active, and 17 in severe, P<0.001). Of 14 with severe sarcopenia, 13 had severe UC while 1 had moderate UC. On multivariate analysis, lower body mass index and higher Mayo score were associated with sarcopenia. Of 37 patients with acute severe colitis, 16 had sarcopenia. Requirement of second-line therapy was similar between patients with and without sarcopenia. On follow-up (median: 18 months), there was a non-significant higher rate of major adverse events in those with sarcopenia (47.4% vs. 33.8%, P=0.273). Conclusions Sarcopenia and severe sarcopenia in UC correlate with the disease activity.

Abstract
Cavernous hemangioma, currently known as "cavernous venous malformation," is a common, benign, non-infiltrative, slowly progressive vascular malformation of the orbit presenting in adults. We report the case of a 9-year-old girl who presented with a painless palpable mass over the right upper eyelid of 7 years' duration. A computed tomography scan of the orbits revealed a heterogeneously enhancing, well-circumscribed mass in the right upper eyelid with no orbital extension. A transcutaneous excisional biopsy with histopathology disclosed cavernous venous malformation. The majority of cavernous venous malformations are intraconal and present in the fourth to fifth decade of life.

Abstract
BACKGROUND In complementary and alternative medicinal systems, the Arsenicum album in ultra-high dilution was used in various therapeutic conditions, considering its effects on the body's immune system, including the COVID-19 pandemic. However, scientific evidence regarding its immunomodulatory effects is insufficient. OBJECTIVE The current study aimed to investigate the immunomodulatory effects of Arsenicum album in an experimental mouse model. MATERIALS AND METHODS Immunomodulatory activity of potentized dilutions of Arsenicum album i.e., 6C, 30C, 200C in BALB/c mice was evaluated by humoral antibody titer and delayed- type hypersensitivity assays wherein a fixed concentration (0.5 ml of 1× 109 cells/ml) of freshly prepared sheep RBC was administered as a foreign antigen to generate primary and secondary antibodies. RESULTS Arsenicum album showed significant immunomodulatory activity by increasing primary antibody titer evaluated on day 21 of the treatment in all the dilutions as compared to SRBC and vehicle control group in humoral immune response assay without showing any effect on delayed-type hypersensitivity. CONCLUSION The results of this preliminary study indicate that oral administration of Arsenicum album has the potential to augment primary humoral response at all dilutions. Hence, the possibility of using the Arsenicum album could be explored to treat immunological conditions, infections, etc., as an alternative therapy alongwith modern medicines.

Abstract
A one-pot, tandem reductive annulation of 2-nitrobenzenesulfonamides with aldehydes to the synthesis of substituted 3,4-dihydro-2H-1,2,4-benzothiadiazine-1,1-dioxides in the presence of sodium dithionite (Na2S2O4) is reported under mild conditions. The method involves in situ reduction of the nitro group followed by condensation with aldehydes to form an imine, which upon subsequent intramolecular cyclization forms the product under one-pot conditions. The protocol features use of inexpensive Na2S2O4 as the exclusive reagent, appreciable functional group tolerance, broad substrate scope, high product yields, and scalability.

Abstract
This study aims to evaluate the feasibility and utility of virtual reality (VR) for baffle planning in congenital heart disease (CHD), specifically by creating patient-specific 3D heart models and assessing a user-friendly VR interface. Patient-specific 3D heart models were created using high-resolution imaging data and a VR interface was developed for baffle planning. The process of model creation and the VR interface were assessed for their feasibility, usability, and clinical relevance. Collaborative and interactive planning within the VR space were also explored. The study findings demonstrate the feasibility and usefulness of VR in baffle planning for CHD. Patient-specific 3D heart models generated from imaging data provided valuable insights into complex spatial relationships. The developed VR interface allowed clinicians to interact with the models, simulate different baffle configurations, and assess their impact on blood flow. The VR space's collaborative and interactive planning enhanced the baffle planning process. This study highlights the potential of VR as a valuable tool in baffle planning for CHD. The findings demonstrate the feasibility of using patient-specific 3D heart models and a user-friendly VR interface to enhance surgical planning and patient outcomes. Further research and development in this field are warranted to harness the full benefits of VR technology in CHD surgical management.

Abstract
Radiologists across many imaging modalities commonly encounter gallbladder adenomyomatosis. The classic imaging appearances of gallbladder adenomyomatosis are well described and confirm benignity. However, in clinical practice, adenomyomatosis can be challenging to differentiate from other gallbladder pathologies that require cholecystectomy. In this article, we describe the common and uncommon appearances of gallbladder adenomyomatosis on multimodality imaging, helping differentiate adenomyomatosis from non-benign gallbladder abnormalities. Accurately differentiating adenomyomatosis from its mimics provides the surgical team with important clinical and surgical management information, improving patient outcomes.

Abstract
Discovery and optimization of a biotherapeutic monoclonal antibody requires a careful balance of target engagement and physicochemical developability properties. To take full advantage of the sequence diversity provided by different antibody discovery platforms, a rapid and reliable process for humanization of antibodies from nonhuman sources is required. Canonically, maximizing homology of the human variable region (V-region) to the original germline was believed to result in preservation of binding, often without much consideration for inherent molecular properties. We expand on this approach by grafting the complementary determining regions (CDRs) of a mouse anti-LAG3 antibody into an extensive matrix of human variable heavy chain (VH) and variable light chain (VL) framework regions with substantially broader sequence homology to assess the impact on complementary determining region-framework compatibility through progressive evaluation of expression, affinity, biophysical developability, and function. Specific VH and VL framework sequences were associated with major expression and purification phenotypes. Greater VL sequence conservation was correlated with retained or improved affinity. Analysis of grafts that bound the target demonstrated that initial developability criteria were significantly impacted by VH, but not VL. In contrast, cell binding and functional characteristics were significantly impacted by VL, but not VH. Principal component analysis of all factors identified multiple grafts that exhibited more favorable antibody properties, notably with nonoptimal sequence conservation. Overall, this study demonstrates that modern throughput systems enable a more thorough, customizable, and systematic analysis of graft-framework combinations, resulting in humanized antibodies with improved global properties that may progress through development more quickly and with a greater probability of success.

Abstract
Conventional three-dimensional (3D)-printed hydroxyapatite (HA)-based constructs have limited utility in bone tissue engineering due to their poor mechanical properties, elevated risk of microbial infection, and limited pore interconnectivity. 3D printing of complex multiple components to fabricate fully interconnected scaffolds is a challenging task; here, in this work, we have developed a procedure for fabrication of printable ink for complex systems containing multinanomaterials, i.e., HAACZ (containing 1 wt % Ag, 4 wt % CeO2, and 6 wt % ZnO) with better shear thinning and shape retention properties. Moreover, 3D-printed HAACZ scaffolds showed a modulus of 143.8 GPa, a hardness of 10.8 GPa, a porosity of 59.6%, effective antibacterial properties, and a fully interconnected pore network to be an ideal construct for bone healing. Macropores with an average size of ∼469 and ∼433 μm within the scaffolds of HA and HAACZ and micropores with an average size of ∼0.6 and ∼0.5 μm within the strut of HA and HAACZ were developed. The distribution of fully interconnected micropores was confirmed using computerized tomography, whereas the distribution of micropores within the strut was visualized using Voronoi tessellation. The water contact angle studies revealed the most suitable hydrophilic range of water contact angles of ∼71.7 and ∼76.6° for HA and HAACZ, respectively. HAACZ scaffolds showed comparable apatite formation and cytocompatibility as that of HA. Antibacterial studies revealed effective antibacterial properties for the HAACZ scaffold as compared to HA. There was a decrease in bacterial cell density for HAACZ from 1 × 105 to 1.2 × 103 cells/mm2 against Gram-negative (Escherichia coli) and from 1.9 × 105 to 5.6 × 103 bacterial cells/mm2 against Gram-positive (Staphylococcus aureus). Overall, the 3D-printed HAACZ scaffold resulted in mechanical properties, comparable to those of the cancellous bone, interconnected macro- and microporosities, and excellent antibacterial properties, which could be utilized for bone healing.

Abstract
BACKGROUND The radiological differentiation of xanthogranulomatous cholecystitis (XGC) and gallbladder cancer (GBC) is challenging yet critical. We aimed at utilizing the deep learning (DL)-based approach for differentiating XGC and GBC on ultrasound (US). METHODS This single-center study comprised consecutive patients with XGC and GBC from a prospectively acquired database who underwent pre-operative US evaluation of the gallbladder lesions. The performance of state-of-the-art (SOTA) DL models (GBCNet-convolutional neural network [CNN] and RadFormer, transformer) for XGC vs. GBC classification in US images was tested and compared with popular DL models and a radiologist. RESULTS Twenty-five patients with XGC (mean age, 57 ± 12.3, 17 females) and 55 patients with GBC (mean age, 54.6 ± 11.9, 38 females) were included. The performance of GBCNet and RadFormer was comparable (sensitivity 89.1% vs. 87.3%, p = 0.738; specificity 72% vs. 84%, p = 0.563; and AUC 0.744 vs. 0.751, p = 0.514). The AUCs of DenseNet-121, vision transformer (ViT) and data-efficient image transformer (DeiT) were significantly smaller than of GBCNet (p = 0.015, 0.046, 0.013, respectively) and RadFormer (p = 0.012, 0.027, 0.007, respectively). The radiologist labeled US images of 24 (30%) patients non-diagnostic. In the remaining patients, the sensitivity, specificity and AUC for GBC detection were 92.7%, 35.7% and 0.642, respectively. The specificity of the radiologist was significantly lower than of GBCNet and RadFormer (p = 0.001). CONCLUSION SOTA DL models have a better performance than radiologists in differentiating XGC and GBC on the US.

Abstract
BACKGROUND Endoscopic ultrasound (EUS)-guided drainage is the standard of care for drainage of pancreatic necrosis. Though initially it was mainly used for drainage of only walled-off necrosis, recently, a few studies have also shown its safety in the management of acute necrotic collections. We did a retrospective study to evaluate the safety and efficacy of EUS-guided drainage in the early phase of pancreatitis as compared to interventions in the late phase. METHODS We retrieved baseline disease-related, procedure-related and outcome-related details of patients who underwent EUS-guided drainage of pancreatic necrosis. Patients were divided into early (≤ 28 days from onset of pancreatitis) or delayed (> 28 days) drainage groups. Both groups were compared for disease-related characteristics and outcomes. RESULTS Total 101 patients were included in the study. The mean age of included patients was 35.54 ± 13.58 years and 75 were male. Thirty-five patients (34.7%) underwent early drainage. In the early group, a majority of patients underwent intervention due to infected collection (88.6% vs. 18.2%; p < 0.001). More patients in the early group had < 30% wall formation (28.6% vs. 0%; p < 0.001) and > 30% solid debris within the collection (42.9% vs. 15.2%; p = 0.005). Patients in the early group were also more likely to require endoscopic necrosectomy (57.1% vs. 27.3%; p = 0.003) and additional percutaneous drainage (31.4% vs. 12.1%; p = 0.018). Overall, three patients in the early group and one patient in the delayed group had procedure-related complications. Four patients in the early group and one patient in the delayed group succumbed to illness (p = 0.029). CONCLUSION Though delayed interventions remain standard of care in the management of acute pancreatitis, some patients may require early intervention due to infected collection with deteriorating clinical status. Early EUS-guided interventions in such carefully selected patients have in similar clinical outcomes and complication rates compared to delayed intervention. However, such patients are more likely to require additional endoscopic or percutaneous interventions.

Abstract
A prevalent psychiatric disorder called Child Separation Anxiety Disorder (SAD) is characterized by extreme discomfort when a child gets separated from their primary carers. While SAD's quick consequences on kids are well-researched, its long-term implications for teenage psychopathology have received less attention. This longitudinal study aims to ascertain the connection between child SAD and future psychopathological consequences in adolescents. 500 adolescents were chosen as part of the adolescent depression project, and at the age of 17, we retrospectively evaluated past and present mental disorders. At ages 25 and 32, they conducted diagnostic evaluations of these people during adolescence while they continued to monitor them. Based on childhood/adolescent assessments, the participants were split into different groups: SAD (n=34), other forms of Anxiety (n=76), a control group with combined psychiatric conditions (n=205), and mentally sound control group (n=185). Statistics were evaluated by hierarchical multiple logistic regression after various illnesses and pertinent demographic variables were considered. It implies that SAD has a high risk (80.2%) of being a significant risk indicator for the emergence of mental illnesses in young adults. This study highlights the importance of early SAD management and therapy and the possible advantages of treating SAD in lowering the likelihood of developing other mental health problems in adolescence. It also emphasizes the value of continuous studies to comprehend these connections and enhance the effects on SAD sufferers' psychological well-being.

Abstract
BACKGROUND The data evaluating contrast-induced-acute kidney injury (AKI) in patients with acute pancreatitis is scarce. This study aimed to compare the frequency of AKI in patients with acute necrotizing pancreatitis undergoing non-contrast computed tomography (NCCT) with those undergoing contrast-enhanced computed tomography (CECT) during hospitalization. METHODS This prospective randomized controlled trial (CTRI/2019/12/022206) screened consecutive patients with acute pancreatitis for eligibility and randomly allocated patients with acute necrotizing pancreatitis (based on CECT in the first week of illness) and normal renal functions to receive either NCCT or CECT during hospitalization. The incidence of development of new AKI and clinical outcomes was compared between the two groups. Post-hoc analysis was done to adjust for disease severity. RESULTS As many as 105 patients completed the study as per protocol (NCCT = 45 and CECT = 60). AKI occurred in 36 (34.3%) patients, nine (20%) in the NCCT and 27 (45%) in the CECT group. Contrast induced-AKI occurred in 11 (18.3%) patients, while 25 had AKI secondary to acute pancreatitis. The relative risk (RR) of AKI in the CECT group was 2.25 (95% CI 1.17-4.30, p = .0142). The frequency of intensive care unit (ICU) admission (RR = 2.1, 95% CI 1.34-3.27, p = .0001) and need for drainage of collections (RR = 1.39, 95% CI 1.1-1.7, p = .005) was significantly higher and the length of hospitalization (p = .001) and ICU admission (p = 0.001) were significantly longer in the CECT group. However, when adjusted for the severity of acute pancreatitis, there was no difference in AKI and clinical outcomes between the NCCT and CECT groups. The duration of AKI was significantly longer and the need for dialysis was significantly higher in patients who had AKI secondary to acute pancreatitis compared to those with contrast induced-AKI (p = .003). CONCLUSION CECT is not significantly associated with AKI in acute necrotizing pancreatitis.

Abstract
A major issue among adolescents in recent years has been social isolation, or the sensation cut off and alone from peers and society. The effects of social isolation on youngsters and adolescents are investigated with special attention paying to the possible negative effects on their physical and mental health. Multiple studies have shown a link between adversity in life domains and adolescent social isolation. Firstly, it can have a major effect on mental health, raising the probability of experiencing things like anxiety, sadness and even suicidal thoughts. Second, it prevents the development of vital social abilities, making it harder to make and keep close friends. In addition, social isolation is associated with worse academic performance, which in turn reduces the number of courses a student can take and the number of jobs they can have in the future. After looking over 520 papers, 15 were chosen for the systematic review. Four researches reported the implications on general health, while two investigations reported on ramifications affecting the Hypothalamic-pituitary-adrenal (HPA) axis area along with social and mental growth of children. In conclusion, social isolation affects youth development across a wide spectrum, including psychological well-being, interpersonal skills, and academic success. Children and adolescents who experience isolation are more likely to suffer from anxiety and sadness, according to the review's findings. Cortical levels rise and mental growth slows in socially isolated children. Children and adolescents should be monitored by health professionals during and after the COVID-19 pandemic to ensure that their mental and physical health needs are met.

Abstract
This paper targets the nuclease activity of polymeric chemical compounds toward bacterial genomic DNA and also elucidates their probable drug-like properties against the enzymes bacterial gyrase complex and human topoisomerase. Poly-o-chloroaniline, poly-m-chloroaniline, and poly-o,m-chloroaniline were synthesized by a chemical oxidation method. The structure of the polymers was characterized by the powder X-ray diffraction pattern, which suggested the ordered structure of the polymer, where the parallel and perpendicular periodicities of the polymeric chain were arranged systematically. The molecular transition of polymers was determined by a UV-visible spectrum study. A polymeric arrangement of the molecule can be seen in scanning electron microscopy (SEM) images. Among the three polymers chosen for the biological study and molecular docking studies, poly-m-chloroaniline showed more affinity to bind against both the selected targets (HT IIIb TB and SAGS) in comparison to the ortho- and ortho-meta substituents of polyaniline. The biophysical interaction analysis is in line with molecular docking, which shows that poly-m-chloroaniline forms many different categories of interactions and binds very strongly with the selected targets. The synthesized and tested molecules have potential nuclease activity, which is well aligned with molecular docking studies against the bacterial gyrase complex and human topoisomerase.

Abstract
BACKGROUND Plant-derived homeopathic medicines (HMs) are cheap and commercially available but are mechanistically less explored entities than conventional medicines. PURPOSE The aim of our study was to evaluate the impact of selected plant-derived HMs derived from Berberis aquifolium (BA), Berberis vulgaris (BV), Mentha piperita (MP), Curcuma longa (CL), Cinchona officinalis (CO), Thuja occidentalis (TO) and Hydrastis canadensis (HC) on cervical cancer (CaCx) cells in vitro. METHODS We screened the mother tincture (MT) and 30C potencies of the above-mentioned HMs for anti-proliferative and cytotoxic activity on human papillomavirus (HPV)-negative (C33a) and HPV-positive CaCx cells (SiHa and HeLa) by MTT assay. Total phenolic content (TPC) and the free-radical scavenging activity of each HM was also determined using standard assays. Phytochemicals reportedly available in these HMs were examined for their potential inhibitory action on HPV16 E6 by in silico molecular docking. RESULTS All tested MTs induced a differential dose-dependent cytotoxic response that varied with cell line. For C33a cells, the order of response was TO > CL > BA > BV > HC > MP > CO, whereas for SiHa and HeLa cells the order was HC > MP > TO > CO > BA > BV > CL and CL > BA > CO, respectively. 30C potencies of all HMs showed an inconsistent response. Further, anti-CaCx responses displayed by MTs did not follow the order of an HM's phenolic content or free radical scavenging activity. Analysis revealed anti-oxidant content of BA, BV and HC had the lowest contribution to their anti-CaCx activity. Using in silico modeling of molecular docking between the HPV16 E6 protein crystallographic structures (6SJA and 4XR8) and main phytochemical components of BV, BA, HC, CL and TO, their potential to inhibit the HPV16 E6 protein carcinogenic interactions was identified. CONCLUSION The study has shown a comparative evaluation of the potential of several plant-derived MTs and HMs to affect CaCx cell line survival in vitro (through cytotoxicity and free radical scavenging) and their theoretical molecular targets in silico for the first time. Data demonstrated that MTs of BA and BV are likely to be the most potent HMs that strongly inhibited CaCx growth and have a strong anti-HPV phytochemical constitution.

Abstract
Background and study aims Recently, larger-caliber metal stents have been increasingly used, resulting in higher efficacy in walled-off necrosis (WON) with more solid debris. However, none of the trials have included WON with significant solid debris. The aim of this study was to compare plastic stents and metal stents for drainage of symptomatic WON with significant solid debris (≥20%). Patients and methods We conducted a single-center, open-label, noninferiority trial including 48 patients. The primary endpoint was treatment success. Secondary outcomes were technical success, total number of procedures, adverse events (AEs), duration of procedure, and treatment failure. All the outcomes were assessed at 3 weeks after drainage. Patients were followed up for 3 months to assess recurrence. Results Treatment succeeded in 21 of 24 patients (87.5%) and 20 of 24 patients (83.3%) in the metal and plastic stent groups, respectively with P =1.05 (95% confidence interval 0.81-1.39). Assuming 10% non-inferiority margin, P <0.001 for non-inferiority, suggesting that plastic stents are non-inferior to metal stents. The technical success rate was 100%. Procedure duration was significantly shorter in the metal stent group (12.95±5.3 minutes versus 29.77±6.6 minutes, P <0.001). The number of total procedures was comparable (2.8±1 vs 2.2±1, P =0.097). There were more minor AEs in plastic stent arm but no significant difference between the two groups. A single asymptomatic recurrence was observed in the metal stent arm. Conclusions Plastic stents are not inferior to metal stents for WON drainage with significant solid debris. However, larger sample-size studies are needed to make definite conclusions.

Abstract
One of the biggest global causes of death is cancer. The side effects of currently available therapies have triggered the search for new drugs. The marine environment, with its vast biodiversity, including sponges, is a rich source of natural products with immense pharmaceutical potential. The aim of the study was to analyze the microbes associated with the marine sponge, Lamellodysidea herbacea, and explore them as resources for anticancer ability. This study includes the isolation of fungi from L. herbacea, and their evaluation for cytotoxic potential against human cancer cell lines such as A-549 (lung), HCT-116 (colorectal carcinoma), HT-1080 (Fibrosarcoma), and PC-3 (prostate) using MTT assay. This revealed that fifteen extracts showed significant anticancer ability (IC50 ≤ 20 µg/mL), at least against one of the cell lines. Three extracts, SPG12, SPG19, and SDHY 01/02, were found significant in terms of anticancer activity, at least against three to four cell lines (IC50 values ≤ 20 µg/mL). The fungus SDHY01/02 was identified by sequencing the internal transcribed spacer (ITS) region as Alternaria alternata. Its extract showed IC50 values < 10 µg/mL against all the tested cell lines and was further analysed through light and fluorescence microscopy. The extract of SDHY01/02 was active (lowest IC50 4.27 µg/mL) against A549 cells in a dose-dependent manner and caused apoptotic cell death. Further, the extract was fractionated and analyzed the constituents by GC-MS (Gas Chromatography-Mass Spectrometry). Di-ethyl ether fraction revealed the constituents (having anticancer activity) such pyrrolo[1,2-a] pyrazine-1,4-dione, hexahydro-3-(2-methyl propyl); 4,5,6,7-tetrahydro-benzo[C]rhiophene-1-carboxylic acid cyclopropylamide; 17-pentatriacontene; 9,12-octadecadienoic acid (Z, Z)-, methyl ester; while DCM fraction contained Oleic acid, eicosyl ester. This is the first report of A. alternata with anticancer potential that has been isolated from the sponge L. herbacea, as far as we are aware.This A. alternata can be exploited to get anticancer molecule(s) in the future.

Abstract
OBJECTIVE The objective of this study was to investigate the potential for erucic acid (EA), an omega-9 monounsaturated fatty acid, to act as a neuroprotective agent. MATERIALS AND METHODS In this study, EA was investigated against N2a cell lines and a rotenone (ROT)-induced model of Parkinson's disease for its neuroprotective potential. The N2a cell line was incubated with fetal bovine serum, penicillin, and streptomycin supplemented with Dulbecco's Modified Eagle's Medium, and the following assays were carried out: (i) MTT, (ii) biocompatibility, (iii) DCFDA, and (iv) diphenylamine. A cell morphology study was also performed. Further, ROT 1 mg/kg s.c. and EA 3 and 10 mg/kg p.o. were given to rats on a daily basis for 21 days, and the following parameters were assessed: (i) neurobehavioral studies, (ii) oxidative stress markers, (iii) neuroinflammatory markers, (iv) neurotransmitters, and (v) histopathological study. RESULTS The cell viability assay revealed that EA showed protection against ROT-induced toxicity in N2a cells, which was confirmed by a cell morphology study. EA decreased oxidative stress and % DNA fragmentation significantly. EA also prevented ROT-induced motor impairment and altered levels of oxidative stress markers, neurotransmitters, and neuroinflammatory markers significantly. When compared to the ROT group, a histological investigation of the EA group showed partial neuronal loss with the existence of intact neurons in between the vacuolated gaps. CONCLUSION This study revealed that EA possesses profound neuroprotective properties in in vitro and in vivo studies. Additional research can be carried out to study the mechanism of EA with respect to its neuroprotective potential.

Abstract
Background The differentiation of benign and malignant gallbladder wall thickening is challenging. The purpose of this study is to evaluate a new sonographic sign, "cervix sign" for differentiation of benign and malignant gallbladder neck thickening. Methods This retrospective study comprised consecutive patients with gallbladder neck thickening who underwent sonography between August 2019 and December 2021. The presence of "cervix sign" was assessed by two radiologists independently. Results Sixty-five patients had gallbladder neck thickening (28 malignant and 37 benign). The sonographic "cervix sign" was present in 18 (64%) patients with malignant thickening and in only one (2.7%) patient with benign thickening (P = 0.0001). The mean wall thickness was greater, and symmetric wall thickening and liver metastases were more common in malignant thickening with "cervix sign" (without reaching statistical significance). There was substantial agreement (kappa = 0.78) between the two observers for the cervix sign. Conclusion Sonographic "cervix sign" is a useful ancillary feature of gallbladder neck cancer.

Abstract
INTRODUCTION Endoscopic dilation is the preferred management strategy for caustic esophageal strictures (CES). However, the differences in outcome for different dilators are not clear. We compared the outcome of CES using bougie and balloon dilators. METHODS Between January 2000 and December 2016, the following data of all the patients with CES were collected: demographic parameters, substance ingestion, number of strictures, number of dilations required to achieve ≥ 14 mm dilation, post-dilation recurrence, and total dilations. Patients were divided into two groups for the type of dilator, i.e., bougie or balloon. The two groups were compared for baseline parameter, technical success, short- and long-term clinical success, refractory strictures, recurrence rates, and major complications. RESULTS Of the 189 patients (mean age 32.17 ± 12.12 years) studied, 119 (62.9%) were males. 122 (64.5%) patients underwent bougie dilation and 67 (35.5%) received balloon dilation. Technical success (90.1% vs. 68.7%, p < 0.001), short-term clinical success (65.6% vs. 46.3%, p value 0.01), and long-term clinical success (86.9% vs. 64.2%, p < 0.01) were higher for bougie dilators compared to balloon dilators. Twenty-four (12.7%) patients developed adverse events which were similar for two groups. On multivariate analysis, use of bougie dilators (aOR 4.868, 95% CI 1.027-23.079), short-term clinical success (aOR 5.785, 95% CI 1.203-27.825), and refractory strictures (aOR 0.151, 95% CI 0.033-0.690) were independent predictors of long-term clinical success. CONCLUSION Use of bougie dilators is associated with better clinical success in patients with CES compared to balloon dilators with similar rates of adverse events.

Abstract
BACKGROUND Streptococcus pneumoniae is leading bacterial cause of community acquired pneumonia and according to World Health Organization, responsible for 14 % death in children. There is effective vaccine available against Streptococcus pneumoniae. Hence the primary objective was to isolate Streptococcus pneumoniae from nasopharyngeal swabs in children aged 2-59 months with and without community acquired pneumonia and to assess their serotypes. METHODS This case-control study was conducted in tertiary teaching institutes in northern India. Hospitalized children, aged 2-59 months, with World Health Organization-defined community acquired pneumonia were included as cases. Age matched healthy controls were recruited from immunization clinic. All enrolments were done after written informed parental consent. Nasopharyngeal swabs were taken from both cases and controls, and were cultured on 5 % sheep blood agar with gentamycin plate for growth of Streptococcus pneumoniae and incubated in a jar at 370 for 18-24 hrs. Quellung reaction test was used for serotyping. RESULTS From March 2017 to December 2022, 2693 children (1910 cases and 783 controls), were recruited. The median age of cases was 7 months and controls 10 months. Almost all the cases had received antibiotics prior to hospitalization. Streptococcus pneumoniae positivity in nasopharyngeal swab was 8.1 % in cases, of which 56.8 % were vaccine serotypes and 23.6 % in controls, of which 37.8 % were vaccine serotypes. Adjusted odds ratio of isolating vaccine serotypes among cases as compared to controls was 1.77 (95 % CI, 1.09-2.88). CONCLUSION Streptococcus pneumoniae isolation from nasopharyngeal was found to be in lower proportion in cases as compared to control, though colonization with vaccine serotypes was higher in cases as compared to control. Therefore, pneumococcal vaccine coverage must be increased to prevent community acquired pneumonia.

Abstract
It is challenging to differentiate between tuberculous peritonitis and peritoneal carcinomatosis due to their insidious nature and intersecting symptoms. Computed tomography (CT) is the modality of choice in evaluating diffuse peritoneal disease. We conducted an ambispective analysis of patients suspected as having tuberculous peritonitis or peritoneal tuberculosis between Jan 2020 to Dec 2021. The study aimed to identify the clinical and radiological features differentiating the two entities. We included 44 cases of tuberculous peritonitis and 45 cases of peritoneal carcinomatosis, with a median age of 31.5 (23.5-40) and 52 (46-61) years, respectively (p ≤ 0.001). Fever, past history of tuberculosis, and loss of weight were significantly associated with tuberculous peritonitis (p ≤ 0.001, p = 0.038 and p = 0.001). Pain in the abdomen and history of malignancy were significantly associated with peritoneal carcinomatosis (p = 0.038 and p ≤ 0.001). Ascites was the most common radiological finding. Loculated ascites, splenomegaly and conglomeration of lymph nodes predicted tuberculous peritonitis significantly (p ≤ 0.001, p = 0.010, p = 0.038). Focal liver lesion(s) and nodular omental involvement were significantly associated with peritoneal carcinomatosis (p = 0.011, p = 0.029). The use of clinical features in conjunction with radiological findings provide better diagnostic yields because of overlapping imaging findings.
