[PMID: 38357712 DOI: 10.1111/ijlh.14243] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/16/2023] [Accepted: 01/10/2024] [Indexed: 02/16/2024]
Abstract
BACKGROUND Altered T-cell repertoire with an aberrant T-cell activation and imbalance of the Th17/Treg cells has been reported in acquired aplastic anemia (aAA). miRNAs are well known to orchestrate T-cell activation and differentiation, however, their role in aAA is poorly characterized. The study aimed at identifying the profile of miRNAs likely to be involved in T-cell activation and the Th17/Treg-cell imbalance in aAA, to explore newer therapeutic targets. METHODS Five milliliters peripheral blood samples from 30 patients of aAA and 15 healthy controls were subjected to flow cytometry for evaluating Th17- and Treg-cell subsets. The differential expression of 7 selected miRNAs viz; hsa-miR-126-3p, miR-146b-5p, miR-155-5p, miR-16, miR-17, miR-326, and miR-181c was evaluated in the PB-MNCs. Expression analysis of the miRNAs was performed using qRT-PCR and fold change was calculated by 2-ΔΔCt method. The alterations in the target genes of deregulated miRNAs were assessed by qRT-PCR. The targets studied included various transcription factors, cytokines, and downstream proteins. RESULTS The absolute CD3+ lymphocytes were significantly elevated in the PB of aAA patients when compared with healthy controls (p < 0.0035), however, the CD4:CD8 ratio was unperturbed. Th17: Treg-cell ratio was altered in aAA patients (9.1 vs. 3.7%, p value <0.05), which correlated positively with disease severity and the PNH positive aAA. Across all severities of aAA, altered expression of the 07 miRNAs was noted in comparison to controls; upregulation of miR-155 (FC-2.174, p-value-0.0001), miR-146 (FC-2.006, p-value-0.0001), and miR-17 (FC-3.1, p-value-0.0001), and downregulation of miR-126 (FC-0.329, p-value-0.0001), miR-181c (FC-0.317, p-value-0.0001), miR-16 (FC-0.348, p-value-0.0001), and miR-326 (FC-0.334, p-value-0.0001). Target study for these miRNAs revealed an increased expression of transcription factors responsible for Th1 and Th17 differentiation (T-bet, RORϒt, IL-17, IL-6, and IFN-ϒ), T-cell activation (NFκB, MYC, and PIK3R2), downregulation of FOX-P3, and other regulatory downstream molecules like SHIP-1, ETS-1, IRAK-1, TRAF-6, and PTEN. CONCLUSION The study for the first time highlights the plausible role of different miRNAs in deregulating the Th17/Treg-cell imbalance in aAA, and comprehensively suggest the role of altered NF-kB and mTOR pathways in aAA. The axis may be actively explored for development of newer therapeutic targets in aAA.

Identification and mechanistic exploration of structural and conformational dynamics of NF-kB inhibitors: rationale insights from in silico and in vitro studies. J Biomol Struct Dyn 2024; 42:1485-1505. [PMID: 37054525 DOI: 10.1080/07391102.2023.2200490] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/06/2023] [Accepted: 04/02/2023] [Indexed: 04/15/2023]
Abstract
Increased expression of target genes that code for proinflammatory chemical mediators results from a series of intracellular cascades triggered by activation of dysregulated NF-κB signaling pathway. Dysfunctional NF-kB signaling amplifies and perpetuates autoimmune responses in inflammatory diseases, including psoriasis. This study aimed to identify therapeutically relevant NF-kB inhibitors and elucidate the mechanistic aspects behind NF-kB inhibition. After virtual screening and molecular docking, five hit NF-kB inhibitors opted, and their therapeutic efficacy was examined using cell-based assays in TNF-α stimulated human keratinocyte cells. To investigate the conformational changes of target protein and inhibitor-protein interaction mechanisms, molecular dynamics (MD) simulations, binding free energy calculations together with principal component (PC) analysis, dynamics cross-correlation matrix analysis (DCCM), free energy landscape (FEL) analysis and quantum mechanical calculations were carried out. Among identified NF-kB inhibitors, myricetin and hesperidin significantly scavenged intracellular ROS and inhibited NF-kB activation. Analysis of the MD simulation trajectories of ligand-protein complexes revealed that myricetin and hesperidin formed energetically stabilized complexes with the target protein and were able to lock NF-kB in a closed conformation. Myricetin and hesperidin binding to the target protein significantly impacted conformational changes and internal dynamics of amino acid residues in protein domains. Tyr57, Glu60, Lys144 and Asp239 residues majorly contributed to locking the NF-kB in a closed conformation. The combinatorial approach employing in silico tools integrated with cell-based approaches substantiated the binding mechanism and NF-kB active site inhibition by the lead molecule myricetin, which can be explored as a viable antipsoriatic drug candidate associated with dysregulated NF-kB.Communicated by Ramaswamy H.

Research Note: Effect of dietary xylo-oligosaccharide on growth performance, intestinal histomorphology, and specific cecal bacteria in broiler chickens. Poult Sci 2024; 103:103189. [PMID: 37939588 PMCID: PMC10665916 DOI: 10.1016/j.psj.2023.103189] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/28/2023] [Revised: 09/29/2023] [Accepted: 10/09/2023] [Indexed: 11/10/2023] Open
Abstract
This study was conducted to evaluate the prebiotic effect of xylo-oligosaccharide (XOS) supplemented in a corn-soybean meal (SBM) based conventional diet on growth performance, intestinal histomorphology, and quantification of specific bacteria in the ceca of broilers. A total of 240 d of hatch Cobb 500 male broiler chicks were randomly assigned to 4 dietary treatments (corn-SBM-based control diet) containing 0, 0.05, 0.1, and 0.2% XOS. The broilers were raised for 21 d in 6 replicate cages, each containing 10 birds. Growth performance parameters were obtained weekly. Additionally, small intestinal tissues were collected to evaluate histomorphometry and whole ceca were collected to quantify bacterial populations on D21. The results showed that inclusion of XOS has similar body weight (BW), body weight gain (BWG), feed intake (FI), and feed conversion ratio (FCR) as the control group during the 21-day study. The results further indicate a tendency for the jejunum villus to crypt ratio (VH:CD) to increase in birds given 0.05 and 0.2% XOS (P = 0.08). Cecal bacteria quantification showed a linear increase in Bifidobacterium with increasing XOS levels (P < 0.0001) and a decrease Clostridium perfringens levels compared to birds fed the control diet (P < 0.0001). However, there were no differences in the total counts of Lactobacillus and E. coli. Together these results showed that while there were no differences in growth parameters up to 21 d, the histomorphology findings and the increase in Bifidobacterium, along with the reduction in C. perfringens observed in the XOS groups, suggest a beneficial impact of XOS inclusion on gut health. Further research with longer feeding periods and higher XOS levels should be conducted to explore potential positive effects on both growth and gut health parameters.

"Primary" bulbar urethral ischemic necrosis following pelvic fracture urethral injury: A rare surgical challenge. Indian J Urol 2024; 40:62-64. [PMID: 38314075 PMCID: PMC10836446 DOI: 10.4103/iju.iju_329_23] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/27/2023] [Revised: 09/26/2023] [Accepted: 11/23/2023] [Indexed: 02/06/2024] Open
Abstract
Ischemic necrosis of the bulbar urethra in a patient with pelvic fracture urethral injury without a prior history of surgical intervention is extremely rare and results in long-segment obliterative strictures that are difficult to manage. Instead of the more traditional approach of vascular reconstruction followed by transpubic end-to-end urethroplasty, these patients are better managed by up-front urethroplasty with a tubed flap or as a staged procedure with grafting and tubularization. Herein, we report a case of primary bulbar urethral ischemic necrosis due to pelvic fracture managed with tubularized preputial flap (McAninch flap) urethroplasty.

Urodynamic assessment of detrusor function in the very acute phase of traumatic spinal cord injury: A prospective cohort study. Indian J Urol 2024; 40:31-36. [PMID: 38314069 PMCID: PMC10836447 DOI: 10.4103/iju.iju_315_23] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/17/2023] [Revised: 12/04/2023] [Accepted: 12/18/2023] [Indexed: 02/06/2024] Open
Abstract
Introduction The bladder is believed to be acontractile due to the phase of spinal shock and there is a lack of data on the detrusor function within the first few days after spinal cord injury (SCI). This study intended to assess the detrusor function with invasive urodynamics (UDS) during the first 15 days of SCI. Methods This prospective observational study was carried out from January 2020 to June 2021 and consecutive stable patients older than 18 years of age who had a history of traumatic SCI within the past 15 days were screened for inclusion. For each patient, the International Standards for Neurological Classification of SCI Worksheet was filled. All patients underwent bedside invasive UDS within 15 days of injury. Results There were a total of 41 patients with a mean age of 35 years. The thoracic cord was most commonly involved (46.3%) with Type A AISA grade being the most common (68.2%). The mean duration of injury at the time of UDS was 6 days. Abnormality in the filling phase could be identified in six patients. Three patients had neurogenic detrusor overactivity (NDO), with one having a high-pressure phasic NDO and one having a sustained NDO. Two patients had poor compliance and one had borderline poor compliance. None of the patients generated any detrusor pressure during voiding cystometry. Conclusions In patients with SCI, 14.5% of the patients had abnormal findings during the filling phase on the UDS performed within 15 days of the injury. These findings are in stark contrast to the traditional understanding that the detrusor is acontractile during the early phase of the SCI and merit further evaluation.

Miller-Fisher Syndrome Unveiled in the Presence of Cholangiocarcinoma. Cureus 2023; 15:e49016. [PMID: 38111454 PMCID: PMC10727167 DOI: 10.7759/cureus.49016] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Accepted: 11/17/2023] [Indexed: 12/20/2023] Open
Abstract
Miller-Fisher syndrome (MFS) is a rare variant of Guillain-Barré syndrome, characterized by ataxia, areflexia, ophthalmoplegia, and possible facial, swallowing and limb weakness alongside respiratory failure. Variations within MFS may include respiratory and limb weakness and Bickerstaff brainstem encephalitis (BBE), marked by altered consciousness, ataxia, ophthalmoparesis, and paradoxical hyperreflexia. MFS can emerge in both children and adults, often following bacterial or viral illness. While autoimmune-driven nerve damage occurs, most MFS patients recover within six months without specific treatment, with a low risk of lasting neurological deficits or relapses. Rarely fatal, MFS's co-occurrence with cholangiocarcinoma (CCA) presents unique management challenges. CCA, primarily affecting bile ducts, has a bleak prognosis; surgical resection offers limited cure potential due to late-stage detection and high recurrence rates. Advances in CCA's molecular understanding have led to novel diagnostic and therapeutic approaches, requiring a comprehensive interdisciplinary care approach for optimal MFS and CCA management outcomes. Herein, we present a 50-year-old male with a complex medical history who was admitted to the hospital due to abdominal discomfort, nausea, vomiting, and ascites. Imaging revealed pneumonia and secondary bacterial peritonitis. Later, he developed neurological symptoms, including weakness, gait abnormalities, and brainstem symptoms, leading to the diagnosis of MFS. Despite treatment efforts, his condition deteriorated, leading to acute liver failure and unexplained anasarca. N-acetyl cysteine was initiated for liver issues. Neurologically, he showed quadriparesis and areflexia. Intravenous immunoglobulin (IVIG) treatment improved his neurological symptoms but worsened gastrointestinal issues, including ileus and elevated CA19-9 levels, suggesting a potential carcinoma. A liver biopsy was performed. After IVIG treatment, he experienced widespread discomfort, emotional unresponsiveness, swallowing difficulties, and aspiration risk, ultimately leading to his demise.

EARLY IMPLANT OUTCOMES IN ADULTS WITH DENTAL DECAY TREATED WITH PHOTODYNAMIC TREATMENT. GEORGIAN MEDICAL NEWS 2023:19-26. [PMID: 38236093] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Subscribe] [Scholar Register] [Indexed: 01/19/2024]
Abstract
A fast implant is a kind of implant to place in the cavity right away after dental extraction. These implants are shown to maintain cervical marrow and reduce the number of surgery operations required for patients. The Photodynamic treatment (PDT) uses antimicrobial processes to supplement nonsurgical periodontal therapy. Combined through the scaling and root planning (SRP), and PDT is more effective. This study aims to assess the effects of PDT on initial findings with dental implants (DI) placed in patients having gum disease with SRP against patients who do not at the 12-month follow-up point. An aggregate of 25 implants were inserted in 16 patients, 12 of whom were in the test group (TG) and 13 of whom were in the control group (CG). SRP is conducted toward rapid implant assignment in the control site, while PDT as an adjunct to SRP (SRP + PDT) is executed prior to instant implant insertion in test sites. At the beginning, 4 months, 8 months, and 12 months, gingival index, radiovisiographs, inquiring pocket intensity, clinical attachment level, and plaque index were obtained. Basic durability was assessed after implant insertion, and the recovery index was measured a week later. In this analysis, Analysis of Variance (ANOVA) technique is used to predict tooth decay earlier. The CG experienced 1.10 mm of mean marginal bone loss after the 12-month research period, compared to 0.97 mm for the (SRP + PDT) group. After reaching the CG and TG, the differences in plaque score and probe depth were noteworthy. Clinical indicators compared to the basis in a year revealed unquestionable improvement, including the probing depth gingival index, plaque index and clinical attachment level. Twelve months were spent monitoring the implants in both groups. The little bone loss improved, although it isn't clinically important. The endurance rate for rapid implants in the PDT grouping is the same as that of the group that underwent SRP. The impact of PTD is utilized as a supplement to SRP. Yet, the consequence is marginal. Because of the improved results with PDT, it is used successfully as an addition to SRP.

Elucidating the zinc-binding proteome of Fusarium oxysporum f. sp. lycopersici with particular emphasis on zinc-binding effector proteins. Arch Microbiol 2023; 205:298. [PMID: 37516670 DOI: 10.1007/s00203-023-03638-1] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/01/2023] [Revised: 06/29/2023] [Accepted: 07/14/2023] [Indexed: 07/31/2023]
Abstract
Fusarium oxysporum f. sp. lycopersici is a soil-borne phytopathogenic species which causes vascular wilt disease in the Solanum lycopersicum (tomato). Due to the continuous competition for zinc usage by Fusarium and its host during infection makes zinc-binding proteins a hotspot for focused investigation. Zinc-binding effector proteins are pivotal during the infection process, working in conjunction with other essential proteins crucial for its biological activities. This work aims at identifying and analysing zinc-binding proteins and zinc-binding proteins effector candidates of Fusarium. We have identified three hundred forty-six putative zinc-binding proteins; among these proteins, we got two hundred and thirty zinc-binding proteins effector candidates. The functional annotation, subcellular localization, and Gene Ontology analysis of these putative zinc-binding proteins revealed their probable role in wide range of cellular and biological processes such as metabolism, gene expression, gene expression regulation, protein biosynthesis, protein folding, cell signalling, DNA repair, and RNA processing. Sixteen proteins were found to be putatively secretory in nature. Eleven of these were putative zinc-binding protein effector candidates may be involved in pathogen-host interaction during infection. The information obtained here may enhance our understanding to design, screen, and apply the zinc-metal ion-based antifungal agents to protect the S. lycopersicum and control the vascular wilt caused by F. oxysporum.

Abstract
Although duplication of the collecting system is fairly common, ureteropelvic junction obstruction of the upper moiety in a patient with duplex system is rare, more so if the obstruction is extrinsic and vascular. Herein, we report a case of obstruction of the upper moiety infundibulum by a crossing vein, in a patient with partially duplex system who presented with flank pain and focal hydronephrosis of the superior calyx, a clinical presentation similar to that of Fraley's syndrome. The infundibulum was transected and transposed anterior to the crossing vessel.

Abstract
The objective of the study was to investigate the effects of a dacitic tuff breccia (DTB) on Eimeria-infected broilers. A total of 600 one-day-old Cobb 500 male chickens were randomly assigned to 5 treatments with 10 replicates of 12 birds. Treatments were: an unchallenged control (UC), a challenged (CC) control (0% DTB), and 3 challenged groups with 0.125, 0.25, or 0.5% DTB. At d 14, birds in the CC and DTB groups were orally gavaged with mixed Eimeria spp., while the UC received water. Growth performance was evaluated during prechallenge, challenge, and postchallenge periods (0-14 d; 14-20 d; and 20-26 d, respectively). Gastrointestinal permeability was measured at 5 days postinfection (dpi). Intestinal histology and nutrient digestibility of dry matter (DM), crude protein (CP), and ileal digestible energy (IDE) were measured at 6 dpi. Liver activity of glutathione peroxidase (GSH-Px) was determined at 6 dpi, and concentrations of reduced (GSH) and oxidized glutathione (GSSG) were analyzed at 6 and 12 dpi. Data were analyzed using a linear mixed model analysis and Tukey's test (P ≤ 0.05). From 0 to 14 d, similar average daily gain (ADG) and average daily feed intake (ADFI, P > 0.05) were observed. Gain:feed ratio (GF) was higher in 0.125, 0.25, and 0.5% of DTB than the CC and UC (P < 0.001). From 14 to 20 d, the UC had the highest ADG, ADFI, and GF (P < 0.001). At 5 dpi, intestinal permeability was higher in the challenged groups than the UC. Additionally, the UC showed the highest apparent ileal digestibility of CP, whereas 0.125% DTB had higher CP digestibility than the CC and 0.5% DTB (P < 0.001). At 6 dpi, 0.125% DTB increased GSH-Px activity compared to the CC, 0.5% DTB, and UC (P < 0.001). At 12 dpi, 0.125% DTB showed increased GSH concentration compared to the CC, 0.25% DTB, and 0.5% DTB (P < 0.01). The mild coccidia infection negatively impacted growth performance, apparent ileal nutrient digestibility, intestinal histology, and gastrointestinal integrity in broilers. The use of 0.125% DTB exhibited potential in improving antioxidant responses, apparent ileal digestibility of CP, and growth performance.

Abstract
Glucokinase (GK), an isoform of hexokinase expressed predominantly in liver, pancreas and hypothalamus is crucial to blood glucose management. It is a critical component of the glucose-sensing mechanism of the pancreatic islet cells and glycogen regulation in hepatocytes. GK modulators such as allosteric GKAs (glucokinase activators) and GK-GKRP (glucokinase regulatory protein) disruptors have found potential applications as safer antihyperglycemics. Recent studies have also demonstrated the potential of GK modulators as antiparasitic agents. Researchers targeting GK often undertake the time-consuming task of independently collecting and compiling modulator information due to the lack of any dedicated single-platform resource. Towards this, in the present study we demonstrate the design and development of GlucoKinaseDB (GKDB), a comprehensive, curated, online resource of GK modulators. GKDB contains experimentally derived structural and bioactivity information of 1723 modulators along with their detailed molecular descriptors. The web-interface is user-friendly with features such as in-browser visualization, advanced search queries, cross-links to other databases and original reference etc. The bioactivity and descriptor data can be downloaded in bulk (for entire database) or for individual modulators. The 3D structures are also downloadable in multiple formats. GKDB employs a PHP-based web design with Bootstrap styling and a MySQL database backend. GKDB can be utilized for clinical and molecular research via development of pharmacophore hypotheses, QSAR/QSPR models, predictive machine learning models etc. GKDB is freely accessible online at https://glucokinasedb.in.

Abstract
Therapeutic agents being designed against COVID-19 have targeted either the virus directly or the host cellular machinery. A particularly attractive host target is the ubiquitous and constitutively active serine-threonine kinase, Protein kinase CK2 (CK2). CK2 enhances viral protein synthesis by inhibiting the sequestration of host translational machinery as stress granules and assists in viral egression via association with the N-protein at filopodial protrusions of the infected cell. CK2 inhibitors such as Silmitasertib have been proposed as possible therapeutic candidates in COVID-19 infections. The present study aims to optimize Silmitasertib, develop pharmacophore models and design unique scaffolds to modulate CK2. The lead optimization phase involved the generation of compounds structurally similar to Silmitasertib via bioisostere replacement followed by a multi-stage docking approach to identify drug-like candidates. Molecular dynamics (MD) simulations were performed for two promising candidates (ZINC-43206125 and PC-57664175) to estimate their binding stability and interaction. Top scoring candidates from the lead optimization phase were utilized to build ligand-based pharmacophore models. These models were then merged with structure-based pharmacophores (e-pharmacophores) to build a hybrid hypothesis. This hybrid hypothesis was validated against a decoy set and used to screen a diverse kinase inhibitors library to identify favored chemical features in the retrieved actives. These chemical features include; an anion, an aromatic ring and an H-bond acceptor. Based on the knowledge of these features; de-novo scaffold design was carried out which identified phenindiones, carboxylated steroids, macrocycles and peptides as novel scaffolds with the potential to modulate CK2.Communicated by Ramaswamy H.

Abstract
Abstract
Background
Dyslipidemia is directly related to morbidity and mortality in elderly prostate carcinoma patients. The purpose of this study was to evaluate the effects of androgen deprivation therapy (ADT) on the lipid profile among Indian patients with locally advanced and metastatic prostate carcinoma.
Methods
The prospective database of prostate carcinoma patients, who received ADT and whose lipid profile data for the first two years of treatment with ADT was available, were divided into two groups for retrospective analysis: Group A patients are those who had undergone bilateral orchidectomy, while group B patients received luteinizing hormone-releasing hormone agonist (LHRHa). The data analyzed include baseline characteristics, prostate-specific antigen (PSA), and lipid profile.
Results
A total of 69 eligible patients were divided into two groups: group A—29 patients and group B—40 patients. Patients of both the groups reported a significant decrease in the mean serum PSA level from the commencement of ADT and remained close to nadir level till 24 months. In the group A patients, lipid profile parameters except high-density lipoprotein cholesterol showed statistically insignificant deterioration with maximum impact at 6 months. Among the group B patients, the total cholesterol (11.9%), triglycerides (22.2%), and low-density lipoprotein cholesterol (21.1%) increased significantly at 6 months and returned to the near baseline at 12 months and thereafter persisted at the similar level. The mean very low-density lipoprotein level (15.5%) also increased significantly at 6 months and then showed a gradual decline till 24 months of follow-up.
Conclusions
LHRH agonist used as ADT for prostate carcinoma leads to a statistically significant but clinically insignificant temporary worsening in the lipid profile.

Abstract
BACKGROUND The study was done to evaluate the feasibility, safety and outcomes of a one-stop thyroid clinic (OSTC) in a low- and middle-income country (LMIC) setting. METHODS This was a prospective non-randomised case control study consisting of patients with thyroid nodules evaluated and managed at a tertiary referral centre in an LMIC between February 2019 and January 2020. Patients were divided into two groups based on the kind of preoperative evaluation protocol: OSTC group (n = 118) - OSTC protocol, and control group (CG, n = 108) - routine protocol. RESULTS Baseline clinical characteristics of the two groups including median age (p = 0.13) and gender distribution (p = 0.76) were comparable. The majority of patients in both groups belonged to a low-income group (46.6% vs 47.3%; p = 0.91), followed by a middle-income group (35.6% vs 30.5%; p = 0.41). The median number of outpatient department visits (1 vs 3 days; p = < 0.001), waiting time for neck ultrasonography (1 vs 3 days; p = < 0.0001), fine needle aspiration cytology (1 vs 2 days; p = < 0.0001), and out of pocket expenditure (INR 3 965 vs 6 624; p = < 0.001) was significantly less in the OSTC group compared to the CG. Patients in the OSTC group reported better satisfaction levels (p = < 0.0001). Accuracy of diagnosis did not differ between the two groups (p = 0.14). CONCLUSION OSTC practice is feasible, provides comparative clinical outcomes and seems cost effective in an LMIC. This protocol can be adopted as a routine practice in any health system.

Computational biology insights into genotype-clinical phenotype-protein phenotype relationships between novel SLC26A2 variants identified in inherited skeletal dysplasias. Eur J Med Genet 2022; 65:104595. [PMID: 36007841 DOI: 10.1016/j.ejmg.2022.104595] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/18/2022] [Revised: 07/13/2022] [Accepted: 08/17/2022] [Indexed: 11/29/2022]
Abstract
BACKGROUND Pathogenic variants in the transmembrane sulfate transporter protein SLC26A2 are associated with different phenotypes of inherited chondrodysplasias. As limited data is published from India, in this study we sought to elucidate the molecular basis of inherited chondrodysplasias in an Indian cohort. METHODS Molecular screening of 32 fetuses with antenatally diagnosed lethal skeletal dysplasia was performed by next generation sequencing and Sanger sequencing. The genotype-protein phenotype characterization was done using computational biology techniques like homology modelling, stability and pathogenicity predictions. RESULTS We identified five rare autosomal recessive SLC26A2 [NM_000112.4] variants, including three homozygous c.796dupA(p.Thr266Asnfs*12), c.1724delA(p.Lys575Serfs*10), and c.1375_1377dup(p.Val459dup) and two heterozygous variants (c.532C > T(p.Arg178*)) and (c.1382C > T(p.Ala461Val)) in compound heterozygous form in a total of four foetuses. Genotype-protein phenotype annotations highlighted that the clinically severe achondrogenesis 1B causative c.796dupA(p.Thr266Asnfs*12) and c.1724delA(p.Lys575Serfs*10)variants impact SLC26A2 protein structure by deletion of the protein core and transmembrane STAS domains, respectively. In clinically moderate atelosteogenesis type 2 phenotype, the c.1382C > T(p.Ala461Val) variant is predicted to distort alpha helix conformation and alter the bonding properties and free energy dynamics of transmembrane domains and the c.532C > T(p.Arg178*) variant results in loss of both core transmembrane and STAS domains of the SLC26A2 protein. The c.1375_1377dup(p.Val459dup) variant identified in clinically milder atelosteogenesis type II-diastrophic dysplasia spectrum lethal phenotype is predicted to decrease the Qualitative Model Energy Analysis (QMean), which affects major geometrical aspects of the SLC26A2 protein structure. CONCLUSION We expand the spectrum of SLC26A2 related lethal chondrodysplasia and report three novel variants correlating clinical severity and protein phenotype within the lethal spectrum of this rare dysplasia. We demonstrate the relevance of structural characterization to aid novel variant reclassification to provide better prenatal management and reproductive options to families with lethal antenatal skeletal disorder.

Background
India has among the world's highest burden of cardiovascular disease, potentially contributed by myocardial infarction. Despite growing trouble, there are no known post-discharge programs & randomized trials reporting health status outcomes & quality of life among post-myocardial infarction patients. Cardiac rehabilitation programs reduce mortality, therefore, it is crucial to understand the local burden of the disease, common challenges, public perceptions, develop timely & effective interventional programs.
Purpose
This study aimed to evaluate the effect of a nurse-led lifestyle modification follow-up program on health outcomes & quality of life among post-myocardial infarction patients.
Methods
A two-arm randomized controlled trial was adopted & 104 post-myocardial infarction patients were recruited from August to December 2021. An equal number of participants were randomly assigned to intervention & control group by random number table generator. The control group patients received routine care, while the intervention group was provided routine care along with a nurse-led lifestyle modification follow-up program(health education, educational booklet, & telephone follow- up). A low-cost intervention based on information-motivation-behavioural skill model was developed. It was designed according to the needs of patients to know their risk factors, help patients establish a knowledge base, & adapt to the post-illness lifestyle changes. Data were assessed & compared by using the demographic datasheet, health outcomes datasheet, & MacNew heart disease quality of life questionnaire. All evaluations were conducted at baseline after 12 weeks post-discharge, by face-to-face interview & biophysiological measurements.
Results
The nurse-led lifestyle modification follow-up program was convenient for clinical application. The intervention group showed a appreciable improvement in low density lipoprotein(p=0.045), systolic blood pressure(p=0.009), diastolic blood pressure(p=0.044), body mass index(p=0.043), and NT ProBNP(p=0.007). The program effectively improved the lifestyle behaviours thereby considerably improving the quality of life in all the subscales-physical, emotional & social (p<0.001) after 12 weeks of discharge.
Conclusion
In the Indian context, it is a novel & extensive approach to improve access to health care and emphasizes post-discharge self-management. The greatest benefit of this program was allowing the intervention group participants to consult with us immediately. Since lifestyles vary among different individuals, we considered individuality when providing education & involving them in implementation of an intervention to enhance their confidence & ultimately achieve optimal health outcomes & quality of life. The findings of this study are important for health care professionals caring for post-myocardial infarction patients & direct incorporation of such programs into routine practice to reduce morbidity & mortality.

Abstract
Methotrexate leading to hypercalcaemia is a rarely reported adverse event. We present three elderly patients with inflammatory arthritis who developed hypercalcemia probably due to methotrexate-induced granulomatous pneumonitis. All patients presented with worsening non-productive cough with dyspnea, nausea, loss of appetite, and confusion. Their clinical and radiologic features were consistent with methotrexate-induced pneumonitis. On evaluation, all patients concurrently had hypercalcemia with normal 25OH D3, and low PTH with markedly elevated levels of 1,25OH D3 seen in two patients. In all three patients, hypercalcemia and pneumonia responded to hydration, corticosteroids, and methotrexate withdrawal. There was no relapse of symptoms on long term follow-up. In these three patients with inflammatory arthritis, methotrexate-induced pneumonitis led to symptomatic hypercalcemia. Unless hypercalcemia is looked for and treated in this setting, the morbidity can be high.

Abstract
BackgroundCoronavirus Disease (covid 19) negatively impacted psychosocial health, health care accessibility and exercise regimen but problem’s scope and potential solutions remain elusive. We conducted a patient based online survey to understand these impacts and discussed potential solutions.ObjectivesAssess impact of Covid 19 on rheumatological disease status, accessibility to health care, patient anxiety and behavior and continuation of physical activity during pandemic.MethodsGoogle form (18-question) based questionnaire was sent via SMS/WhatsApp in Aug 2020, at height of first pandemic and responses were collected over next month.ResultsOnly 339 /2700 patients (12.5 %) responded to the survey. Other authors (1)(2) have observed a similar low response rate to online surveys. We recognise questionnaires with fewer questions tend to generate more responses, which should be considered critical in constructing future health-related surveys. Patients’ global assessment of their disease score was 7/10, with 0 representing the worst disease status and10 representing best disease status, also 1/3 patients not felt need for rheumatological consultation during six months (March 2020- Aug 2020) of lockdown. These may imply adequate rheumatic disease control over long periods and during subsequent waves of pandemic, rheumatology patients can be shielded by avoiding non-urgent hospital follow up visits. Significant number of patients (20%) were unable to contact their rheumatologist, implying a significant impact of covid 19 and lockdown on rheumatology care, as suggested by other authors (1). As expected, there was switch to tele consultancy mode of communication, with 22 per cent of patients already using it within 3 months of its introduction, which appears to be a good indicator of future adaptability and feasibility of teleconsultation. Identifying specific profile of patients during physical consultation who can be easily managed via teleconsultation, may reduce unnecessary hospital visits while also improving healthcare delivery. 1/3 of our patients had anxiety about disease flare, and 41 %were concerned about increased risk of covid 19 infection as they were on immunosuppressive medications as noted by other authors (3). Improving access to health care and increasing public awareness could help alleviate this anxiety. Reaching out to isolated rheumatology patients through SMS / educational video may improve the sense of health security. Contrary to our expectations, overall medication adherence was reasonable, likely due to be management of supply chains by local authorities .15% completely stopped exercising and 25% reduced their exercise regimen by 50%. Shifting to home-based exercise, educational videos on physical therapy and online teleconsultation with physiotherapists could overall have positive impact.ConclusionCovid 19 has significantly impacted rheumatological patients in terms of increased anxiety, decreased healthcare accessibility and decreased exercise and physical activities. Modifications in teleconsultation methodology are needed in the future. Patients’ anxiety can be alleviated by educating them through digital and social media platforms and enrolling them in online patient support groups.References[1]Ganapati A, Padiyar S, Nair A, et al.

Abstract
Wnt-β-catenin signaling plays a key role in orthodontic tooth movement (OTM), a common clinical practice for malocclusion correction. However, its targeted periodontal ligament (PDL) progenitor cells remain largely unclear. In this study, we first showed a synchronized increase in Wnt-β-catenin levels and Axin2+ PDL progenitor cell numbers during OTM using immunostaining of β-catenin in wild-type mice and X-gal staining in the Axin2-LacZ knock-in line. Next, we demonstrated time-dependent increases in Axin2+ PDL progenitors and their progeny cell numbers within PDL and alveolar bones during OTM using a one-time tamoxifen-induced Axin2 tracing line (Axin2CreERT2/+; R26RtdTomato/+). Coimmunostaining images displayed both early and late bone markers (such as RUNX2 and DMP1) in the Axin2Lin PDL cells. Conversely, ablation of Axin2+ PDL cells via one-time tamoxifen-induced diphtheria toxin subunit A (DTA) led to a drastic decrease in osteogenic activity (as reflected by alkaline phosphatase) in PDL and alveolar bone. There was also a decrease in new bone mass and a significant reduction in the mineral apposition rate on both the control side (to a moderate degree) and the OTM side (to a severe degree). Thus, we conclude that the Axin2+ PDL cells (the Wnt-targeted key cells) are highly sensitive to orthodontic tension force and play a critical role in OTM-induced PDL expansion and alveolar bone formation. Future drug development targeting the Axin2+ PDL progenitor cells may accelerate alveolar bone formation during orthodontic treatment.

Abstract
Background A midshaft clavicle fracture is a prevalent form of injury of the upper extremity that affects one's quality of life. Several treatment modalities facilitate fixation of the displaced midshaft clavicle to decrease nonunion and malunion of the clavicle fracture. Still, numerous factors influence choosing an optimal surgical intervention. Thus, this study investigates the functional outcome of two standard fixation techniques, titanium elastic nails (TENs) and locking plates, as a prospective comparative study for surgical management of displaced midshaft clavicle fractures. Methods We performed closed/open reduction and internal fixation in 62 patients (40 male and 22 female) with TENs and locking plates, respectively, which were followed up at regular intervals following the surgery (at two, six, 12, 24, and 48 weeks). The surgical outcome was assessed both from functional and radiological standpoints. The influence of surgical fixation on functional outcome was evaluated based on the Constant-Murley score and the fracture recuperation based on union times. Results When compared to plate fixation, TENs had lesser union times. Still, there was no statistical difference in union time between the two groups. The functional assessment graded by Constant-Murley score had a similar distribution of scores between the two groups.With a follow-up of twelve months, the Constant-Murley scores between the groups were not statistically different. While the average score for plate fixation was slightly higher than that of TENs, the nonunion rate was found to be similar in both groups. Conclusion Surgical interventions using both TENs and plate fixation are suitable for managing clavicle midshaft fractures as they have a similar functional outcome. However, considering early recovery with minimal surgical complications, TENs can be a preferred treatment choice for managing displaced midshaft clavicle fractures.

Abstract
Abstract
Aim
This study aims to assess the impact of pre-operative factors on the length of stay in patients following total knee replacement at our institution.
Method
A total of 478 patients following total knee replacement between January 2017-Decemeber 2019 are included in this study. All patients underwent total knee replacement with a medial rotating total knee prosthesis (MRK; Matt Ortho UK).
Data for each patient was collated retrospectively and included the following: Patient demographics (age and sex), American Society of Anaesthesiology (ASA) score, pre-operative range of movement (ROM), Body Mass Index (BMI), and pre-operative haemoglobin. Each factor was then compared with the length of stay for all 478 patients. Statistical significance was sort for each pre-operative factor for both men and women.
Results
Our cohort of patients includes 291 females and 187 males. Patients ranged from 39 to 90 years with an average age of 68. The average BMI of the cohort was 31.3(18.6–56.56) and the average ASA grade was 2.
Preoperative hemoglobin and the Age of the patient at the time of surgery were the only two factors which had a statistically significant impact on the length of hospital stay (p<0.05). BMI, Pre- operative range of motion and ASA scores had no statistically significant effect on the length of hospital stay in our cohort.
Conclusions
Low pre-operative hemoglobin and increasing age have significant effects on length of stay after total knee replacement. The BMI, pre-operative range of movement and ASA scores do not influence the length of hospital stay.

Abstract
This study was performed to investigate the effect of feeding Brassica spp. including full-fat rapeseed, canola meal, and allyl isothiocyanate (AITC) to broiler chicken challenged with E. maxima. A total of 576 one-day old male broiler chicks were completely randomized to 8 treatments with 6 replicated cages and 12 birds per cage. The treatment diets consisted of nonchallenge control (NC, corn-SBM based diet), challenge control (CC), 10% rapeseed (10RS), 30% rapeseed (30RS), 20% canola (20CLM), 40% canola (40CLM), 500 ppm AITC (500AITC), and 1,000 ppm AITC (1000AITC). At d 14, all birds were challenged, except NC group, with a subclinical dose of E. maxima. Intestinal permeability was conducted on 5 d post-infection (dpi) and for oocyst shedding 5 to 6 dpi feces were pooled and collected. On 6 dpi, growth performance, lesion score, histomorphology, and gene expression were measured. The growth performance result showed that 10RS and 30RS groups had lower BW, BWG, FI, and higher FCR (P < 0.0001). During the challenge and overall periods, NC group had highest BW, BWG, and FI, and lowest FCR. The inclusion of canola meal showed lower performance during prechallenge period but was able to catch up BWG during challenge period. The AITC levels showed similar growth performance to CC group. Intestinal permeability for 20CLM, 40CLM, 500AITC and 1000AITC was similar to NC group, whereas CC, 10RS, and 30RS had higher permeability compared to NC (P < 0.0001). Oocyst shedding was significantly lower for 40CLM and NC, whereas all other treatments had higher oocyst shedding (P < 0.0001). All the challenged treatment groups had higher lesion score and microscore than NC (P < 0.0001). Histomorphology data showed that jejunum villus height (VH) for 1000AITC was similar to NC group, whereas CC group had the lowest VH (P = 0.01). The 30RS group had lower VH: crypt depth (CD) ratio in the jejunum and ileum. The gene expression at 6 dpi for claudin1, occludin, IL2, IL6, GLUT5, EAAT, BoAT, and LAT1 was significantly changed among the treatments. The results suggest that 30RS retards growth performance and deteriorate gut health during coccidiosis and should not be fed to chicken during the starter phase. Canola meal showed decline in growth prechallenge but maintained growth and intestinal health during the challenge period at 40% inclusion. AITC at 1,000 ppm showed similar growth as control group, but with improved gut health during the challenge period. Canola meal could be a good alternative to SBM especially during coccidiosis, whereas AITC needs to be tested vigorously in animal feeding regime.

Abstract
Introduction: Injuries resulting from traffic accidents, industrial accidents, natural disasters, and assault are the cause of most fractures of the forearm and it is very important to regain the length, apposition, axial alignment, and rotational alignment of the radius and ulna while treating diaphyseal fractures to achieve a good range of motion. In such cases, open reduction and internal fixation are recommended. Aim: To determine the effectiveness of Locking Compression Plates (LCP) and Dynamic Compression Plates (DCP) in treating adult forearm fractures. Materials and Methods: A prospective interventional study was conducted from September 2020 to September 2021 in which 30 patients with both bone forearm fractures underwent open reduction and internal fixation with a Locking Compression Plate(n=15) or a Dynamic Compression Plate(n=15) at the Dr.D.Y. Patil Medical College, Hospital and Research Centre, Pimpri, Pune, India. For each LCP and DCP operated patient, radiographic findings regarding fracture union and functional outcomes regarding elbow joint range of motion was evaluated. Appropriate parametric tests (Chi-square test, Independent t-test) were conducted to identify significant differences in functional outcomes between the two interventions. Results: Out of total, 13 patients (86.7%) each who underwent both the DCP and LCP fixation had excellent outcomes, though the results were not significant according to Anderson LD et al., grading system. Although it was statistically insignificant (p-value= 0.18), patients who received LCP took less time to heal their fractures than those who received DCP. There was no significant difference between patients treated with DCP and those treated with LCP when it comes to achieving a complete range of motion (p-value=0.99). Conclusion: In terms of functional outcome, both the patient groups who were operated on with DCP as well as LCP had no significant difference. Proper preoperative planning, good patient care, proper surgical technique with minimal adjacent soft tissue damage, strict aseptic conditions, proper follow-up, and rehabilitation along with patient education are all required for good functional outcomes.

Influence of rapeseed, canola meal and glucosinolate metabolite (AITC) as potential antimicrobials: effects on growth performance, and gut health in Salmonella Typhimurium challenged broiler chickens. Poult Sci 2022; 101:101551. [PMID: 34871984 PMCID: PMC8649389 DOI: 10.1016/j.psj.2021.101551] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/05/2021] [Revised: 09/29/2021] [Accepted: 10/12/2021] [Indexed: 12/13/2022] Open
Abstract
Poultry is the major sources of foodborne salmonellosis. Antibiotic resistance and a surge in zoonotic diseases warrant the use of natural alternatives. Glucosinolates (GLs) are naturally occurring antimicrobial compounds in rapeseed and canola. This study investigated the effect of feeding rapeseed, canola meal, and allyl isothiocyanate (AITC; Brassica secondary metabolites) on growth performance (GP), gut health, and the potential antimicrobial activity against nalidixic acid-resistant Salmonella Typhimurium (STNR) in chickens. A total of 640 one-day-old male Cobb 500 broilers were randomly allocated to 8 treatments with 8 replicated cages and 10 birds per cage. Dietary treatments were nonchallenge control (NC, corn-SBM based), challenge (Salmonella) control (CC), 10% rapeseed (10RS), 30% rapeseed (30RS), 20% canola meal (20CLM), 40% canola meal (40CLM), 500 ppm AITC (500AITC), and 1,500 ppm AITC (1500AITC). On d 1, all the birds except NC were orally challenged with STNR (7 log CFU/bird). The chickens were reared for 21 d, and their FI and BW were recorded weekly. Salmonella cecal colonization and fecal shedding were quantified, whereas organ translocation (OT) of STNR to the spleen, liver, and kidney was tested on 0, 3, 6, 13, and 20-d postchallenge (dpc). Data were subjected to one-way ANOVA, and the means were separated by Duncan's test, except mortality and OT data analyzed after transformation by square root of (n +1) (P < 0.05). Overall, feeding 30RS resulted in reduced BW (P = 0.003), BWG (P = 0.003), and FI (P = 0.001) compared to CC, 500AITC, and 1500AITC. Similarly, feeding 20CLM resulted in lower BW and BWG compared to CC (P < 0.05) and increased FCR compared to 1500AITC (P = 0.03). Feeding CC resulted in higher mortality compared to NC and 30RS (P = 0.03). Cecal colonization of STNR was reduced (P < 0.0001) for 30RS on 6 dpc and 500AITC on 6 and 13 dpc (P < 0.0001). Although no difference in gut permeability was observed 6 dpc (P > 0.05), OT of STNR population was the highest for CC in the spleen (P = 0.05). In the liver, 10RS showed reduced OT compared to 20CLM on 13 dpc (P = 0.03), whereas 30RS showed the lowest OT on 6 dpc in the kidney. Fecal shedding was lowest for 30RS on 6 dpc (P = 0.004). Histomorphology showed 30RS had the highest duodenum (P = 0.01) and jejunum (P = 0.02) villus height (VH) and VH to crypt depth (CD) ratio compared to the other treatments, whereas 1500AITC showed similar results to 30RS. Both 30RS and 1500AITC contained comparatively higher functional GL metabolites and were able to maintain gut health. Including higher levels of rapeseed or AITC in poultry feed can reduce Salmonella colonization in the feces and their translocation to other organs.

Abstract
The Education system in India underwent a major change due to the sudden lockdown announced by the Government in view of COVID – 19 pandemic. Both teachers and students had to shift to online mode in a very short time period. The present study analysis the positive and negative aspect of this online mode of education and measures adopted by teachers to maintain the flow of education along with attendance. The sur- vey was conducted at JSS Academy of Technical Education, Noida. More than 100 teachers and students participated in the survey conducted. Also experienced faculty came up with sug- gestions and ideas to improve the online mode of education in view of such pandemic situations. Two teachers who were also teaching kids at an NGO school running in the campus prem- ises shared their view on what efforts they took to let education reach the kids at the NGO as digital divide was the main prob- lem there. Such findings will help in designing a future teach- ing model to cope with pandemic situations and not let educa- tion suffer.

Abstract
The classic retroperitoneal open surgical access to the kidney has been duplicated while performing laparoscopy but is less common than transperitoneal laparoscopy. We reviewed minimally invasive retroperitoneoscopic nephrectomy as a part of the international consultation on urological diseases and European Association of Urology international consultation on minimally invasive surgery in urology. A Pubmed/Medline search was performed to identify studies assessing the feasibility, safety and efficacy of laparoscopic and robotic retroperitoneoscopic nephrectomy. The articles were reviewed to assess outcomes after simple, radical and donor nephrectomy and comparative trials between retroperitoneoscopic versus the open and transperitoneal route were evaluated. Retroperitoneoscopic nephrectomy is feasible for most cases of benign non-functioning kidneys. Retroperitoneoscopic radical nephrectomy is also feasible for most tumours and may be better suited for posteriorly located tumours. Both retroperitoneoscopic and transperitoneal nephrectomy have similar outcomes but the operative time may be shorter for the former. The data are insufficient for robotic retroperitoneoscopic nephrectomy probably because of limited space and lack of benefit of a robot in ablative surgeries. Level of evidence: 3a

Abstract
Purpose: To summarize the scientific published literature on new robotic surgical platforms with potential use in the urological field, reviewing their evolution from presentation until the present day. Our goal is to describe the current characteristics and possible prospects for these platforms. Materials and Methods: A nonsystematic search of the PubMed, Cochrane library's Central, EMBASE, MEDLINE, and Scopus databases was conducted to identify scientific literature about new robotic platforms other than the Da Vinci® system, reviewing their evolution from inception until December 2020. Only English language publications were included. The following keywords were used: "new robotic platforms," "Revo-I robot," "Versius robot," and "Senhance robot." All relevant English-language original studies were analyzed by one author (R.F.) and summarized after discussion with an independent third party (E.M., S.Y., S.P., and M.A.). Results: Since 1995, Intuitive Surgical, Inc., with the Da Vinci surgical system, is the leading company in the robotic surgical market. However, Revo-I®, Versius®, and Senhance® are the other three platforms that recently appeared on the market with available articles published in peer-reviewed journals. Among these three new surgical systems, the Senhance robot has the most substantial scientific proof of its capacity to perform minimally invasive urological surgery and as such, it might become a contender of the Da Vinci robot. Conclusions: The Da Vinci surgical platform has allowed the diffusion of robotic surgery worldwide and showed the different advantages of this type of technique. However, its use has some drawbacks, especially its price. New robotic platforms characterized by unique features are under development. Of note, they might be less expensive compared with the Da Vinci robotic system. We found that these new platforms are still at the beginning of their technical and scientific validation. However, the Senhance robot is in a more advanced stage, with clinical studies supporting its full implementation.

Abstract
OBJECTIVES To evaluate the neurological safety and clinical efficacy of darifenacin and mirabegron in patients with a history of cerebrovascular accident (CVA) who had overactive bladder (OAB) symptoms. METHODS This prospective randomized study, approved by the institute's ethics committee, was carried out at a tertiary care center from December 2018 to June 2020. Treatment naïve adult patients with a past history of CVA with stable neurological status for atleast past 3 months with symptoms of OAB for 3 or more months were included. Eligible patients received either darifenacin or mirabegron for a period of 3 months and various parameters on the 3-day International Consultation on Incontinence Questionnaire (ICIQ) bladder diary, the Montreal Cognitive Assessment-Basic score (MoCA-B), and the adverse events at 3 months posttreatment were compared to that at the baseline. RESULTS A total of 60 patients were included, 30 in each arm. After 3 months of treatment with darifenacin or mirabegron, the majority of the ICIQ bladder diary parameters improved and there was no deterioration in the cognitive function as noted on the MoCA-B score in either of the arms. On intergroup comparison, the mean change in bladder diary parameters and the MoCA-B scores was similar between the two groups. CONCLUSION Darifenacin and mirabegron, in the short term, do not adversely affect the cognitive function in patients with a history of CVA with OAB symptoms. Both are safe and effective treatment options in patients with OAB post-CVA.

Abstract
BACKGROUND Recurrence of periampullary cancer after pancreatoduodenectomy is common. The aim of this study was to investigate patterns of recurrence, incidence, and factors associated with local and distant recurrences. METHODS This retrospective, single-centre study included consecutive patients with periampullary cancer who underwent resection with curative intent from January 2012 to January 2018. Survival, patterns of recurrence, and factors associated with recurrences were analysed. RESULTS Median overall survival (OS) and disease-free survival among 398 included patients was 58.4 and 49.5 months respectively. Twenty-three patients (5.8 per cent) developed isolated local recurrences (LR), 50 (12.6 per cent) developed LR along with distant metastasis (DM), and 103 (25.9 per cent) developed isolated DM. Median OS was 40.4 months for patients with isolated LR versus 23 months for those with DM (P < 0.001). Tumour subtype (distal common bile duct (CBD): odds ratio (OR) 6.18, 95 per cent c.i. 2.19 to 17.46) and node-positive status (OR 2.36, 1.26 to 4.43) were independently associated with higher rates of LR. The most common site for isolated LR was along the superior mesenteric artery (12 of 23 patients). Tumour subtype (distal CBD: OR 2.86, 1.09 to 7.52), nodal positivity (OR 2.46, 1.53 to 3.94), and presence of perineural invasion (OR 1.80, 1.02 to 3.18) were independently associated with DM. CONCLUSION Isolated LR is associated with better survival than DM and occurs most commonly along the superior mesenteric artery.

Abstract
Earthworms (Clitellata, Moniligastridae) of Chaliyar River Malappuram, Eravikulam National Park, Neyyar Wildlife Sanctuary, Parambikulam Tiger Reserve, Peppara Wildlife Sanctuary, Periyar National Park, Shendurney Wildlife Sanctuary and Wayanad Forest, Kerala, a component of the hotspot of Western Ghats, India, were studied by the standard method of taxonomy, and their DNA barcode signatures using the mitochondrial gene cytochrome c oxidase I (COI) were generated for the first time. This study
represents eleven species of earthworms of the family Moniligastridae: Drawida brunnea Stephenson, Drawida circumpapillata Aiyer, Drawida ghatensis Michaelsen, Drawida impertusa Stephenson, Drawida nilamburensis (Bourne), Drawida robusta (Bourne), Drawida scandens Rao, Drawida travancorense Michaelsen, Moniligaster aiyeri Gates, Moniligaster deshayesi Perrier, and Moniligaster gravelyi (Stephenson). In the phylogenetic analysis all the species were recovered in both neighbour–joining (NJ) and maximum likelihood (ML) trees with high clade support. The average K2P distance within and between species was 1.2 % and 22 %, whereas the clear barcode gap of 2–5 % was suggested by barcode gap analysis (BGA) of studied species, reflecting the accuracy of characterization. The study presents the first step in the molecular characterization of the native earthworm family Moniligastridae of India.

Abstract
OBJECTIVE To assess the clinical, urodynamic efficacy, and safety of mirabegron in patients with neurogenic detrusor overactivity (NDO) consequent to traumatic spinal cord injury (SCI). METHODS This prospective cohort study was performed between January 2018 and July 2019 and included adult patients with stable traumatic suprasacral SCI, performing clean intermittent catheterization (CIC), and demonstrating NDO on urodynamic study (UDS). A 3-day bladder diary was made at the baseline after which all patients were started on Mirabegron 50 mg. They were followed up at 6 weeks with a repeat bladder diary and UDS which were compared with those at the baseline. RESULTS A total of 30 patients (4 females, 26 males, mean age: 30.07 years) were included. After 6 weeks of treatment, 5 out of the 29 incontinent patients became completely dry. The mean frequency of CIC decreased from 6.63 at the baseline to 5.37 at 6 weeks (p = .002), the mean CIC volume increased from 275 ml to 341 ml (p = .0002), the mean number of incontinence episodes in between CIC reduced from 3.97 to 2.27 (p < .0001) and time from CIC to leakage increased from 1.73 h to 2.75 h (p < .0001). The mean cystometric capacity increased from 348 ml to 406 ml (p = .008) and the maximum amplitude of NDO decreased from 54 cm H2 O to 41 cm H2 O (p = .005) at 6 weeks. Only two patients reported new onset dry mouth. No major adverse events were noted and none discontinued treatment. CONCLUSION Mirabegron is efficacious and safe in patients with NDO consequent to traumatic SCI.
