Abstract
BACKGROUND There is limited evidence available regarding patient satisfaction and quality of life assessment in patients with extraoral maxillofacial prostheses. OBJECTIVES This systematic review aims to understand the impact of extraoral implant retained prosthesis in improving the quality of life in patients with extraoral maxillofacial defects/abnormalities. METHODS A comprehensive search was performed of nine electronic databases up to August 2022, which yielded three articles that satisfied the inclusion criteria. The study characteristics and findings were extracted, and the included studies were assessed for quality. RESULTS Three cohort studies were selected. Despite the lack of uniformity in the quality of life instruments, there was a general trend in improvement in the quality of life for patients with implant retained extraoral prostheses. The studies were also deemed to be of high quality on assessment. CONCLUSION Given the limitations of this systematic review, there exists limited evidence indicating that implant prostheses may enhance the quality of life for individuals with extraoral maxillofacial defects or abnormalities.

Abstract
The success of CD19 Chimeric antigen receptor (CAR) T-cell therapy in large B-cell lymphoma (LBCL) has been partially offset by toxicity and logistical challenges, which off-the-shelf agents like CD20xCD3 bispecific antibodies might potentially overcome. However, when using CAR T outcomes as the 'standard-of-care comparator̕ for relapsed/refractory (r/r) LBCL, a potential learning curve with implementing a novel, complex therapy like CAR T needs to be considered. To address this, we analysed 726 UK patients intended to be treated with CD19 CAR T for r/r LBCL and compared outcomes between the first year of the national CAR T programme (Era 1; 2019) and the more recent treatment era (Era 2; 2020-2022). We identified significant improvements for Era 2 versus Era 1 in dropout rate (17% vs. 27%, p = 0.001), progression-free survival (1-year PFS 50% vs. 32%, p < 0.001) and overall survival (1-year OS 60% vs. 40%, p < 0.001). We also observed increased use of bridging therapy, improvement in bridging outcomes, more tocilizumab/corticosteroid use, reduced high-grade cytokine release syndrome (4% vs. 9%, p = 0.01) and intensive care unit admissions (20% vs. 32%, p = 0.001). Our results demonstrate significant improvement in CAR T outcomes over time, highlighting the importance of using up-to-date clinical data when comparing CAR T against new treatment options for r/r LBCL.

Abstract
AIM To compare the intraoperative findings with the preoperative imaging in detecting usable root stumps using magnetic resonance imaging (MRI) alone versus MRI combined with high-resolution ultrasonography (HRUS) in adults undergoing post-traumatic brachial plexus (BP) surgery. Further, when root stumps were present, the reliability of their measurements using both imaging methods was compared to their intraoperative length. MATERIALS AND METHODS A consecutive group of adults who were planned for post-traumatic BP surgery between July 2015 and April 2016 were evaluated prospectively. They underwent preoperative MRI and HRUS and the agreement (kappa value) between these imaging methods and their intraoperative findings in categorising roots were then compared. When stumps were present, the reliability of the extraforaminal measurements by each method were compared to their corresponding intraoperative stump length using intraclass correlation coefficients (ICC), and Bland-Altman plots. RESULTS Of the initial 60 patients, 48 patients with 82 roots were included in the study. Greater agreement was observed between HRUS and intraoperative findings in categorising BP root stumps (kappa value 0.70, SE 0.07) versus MRI and intraoperative findings (kappa value 0.42, SE 0.07). Similarly, there was a higher correlation between HRUS and intraoperative findings (ICC: 0.94, p<0.001) than that of MRI and intraoperative findings (ICC: 0.53, p<0.001) regarding stump length measurements. CONCLUSION Combining HRUS with MRI in the preoperative imaging of the adult BP injury can better predict the presence of usable nerve root stumps for intra-plexal nerve grafting. HRUS also gave reliable preoperative stump length measurements, and it was determined that a stump should be at least 1.3 cm to be deemed usable for nerve grafting.

Abstract
BACKGROUND Since the introduction of the combination treatment of anti-programmed death-ligand 1 antibody atezolizumab and anti-VEGF antibody bevacizumab (AB), median overall survival in HCC has drastically improved. However, evidence on the efficacy and safety of the novel treatment standard in patients with prior exposure to systemic treatment is scarce. The aim of this global, multicenter, observational study was to evaluate the efficacy and safety of AB in patients after previous systemic therapy. METHODS We screened our global, multicenter, prospectively maintained registry database for patients who received any systemic therapy before AB. The primary end point was overall survival; secondary end points were time-to-progression, progression-free survival, objective response rate, and safety (rate and severity of adverse events). RESULTS Among 493 patients who received AB for unresectable HCC, 61 patients received prior systemic therapy and were included in this analysis. The median age of the study population was 66 years, with 91.8% males. Predominant risk factors for HCC were viral hepatitis (59%) and alcohol (23%). Overall survival for AB was 16.2 (95% CI, 14.5-17.9) months, time-to-progression and progression-free survival were 4.1 (95% CI, 1.5-6.6) and 3.1 (95% CI, 1.1-5.1) months, respectively. The objective response rate was 38.2% (7.3% with complete and 30.9% with partial response). Overall survival was not influenced by treatment line (2nd vs. >2nd) or previous systemic treatment modality (tyrosine kinase inhibitors vs. immune checkpoint inhibitors). Treatment-related adverse events of all grades according to Common Terminology Criteria for Adverse Events were documented in 42.6% of patients, with only 13.1% of grade ≥3, including one death. CONCLUSION In this observational study, AB emerges as a safe and efficacious treatment option in patients with HCC previously treated with other systemic therapy.

Abstract
Neutrophils are key first responders to Clostridioides difficile infection (CDI). Excessive tissue and blood neutrophils are associated with worse histopathology and adverse outcomes, however their functional role during CDI remains poorly defined. Utilizing intestinal epithelial cell (IEC)-neutrophil co-cultures and a pre-clinical animal model of CDI, we show that neutrophils exacerbate C. difficile -induced IEC injury. We utilized cutting-edge single-cell transcriptomics to illuminate neutrophil subtypes and biological pathways that could exacerbate CDI-associated IEC damage. As such, we have established the first transcriptomics atlas of bone marrow (BM), blood, and colonic neutrophils after CDI. We found that CDI altered the developmental trajectory of BM and blood neutrophils towards populations that exhibit gene signatures associated with pro-inflammatory responses and neutrophil-mediated tissue damage. Similarly, the transcriptomic signature of colonic neutrophils was consistent with hyper-inflammatory and highly differentiated cells that had amplified expression of cytokine-mediated signaling and degranulation priming genes. One of the top 10 variable features in colonic neutrophils was the gene for neutrophil glycoprotein, Olfactomedin 4 (OLFM4). CDI enhanced OLFM4 mRNA and protein expression in neutrophils, and OLFM4 + cells aggregated to areas of severe IEC damage. Compared to uninfected controls, both humans and mice with CDI had higher concentrations of circulating OLFM4; and in mice, OLFM4 deficiency resulted in faster recovery and better survival after infection. Collectively, these studies provide novel insights into neutrophil-mediated pathology after CDI and highlight the pathogenic role of OLFM4 + neutrophils in regulating CDI-induced IEC damage. One Sentence Summary Utilizing single-cell transcriptomics, IEC-epithelial co-cultures, and pre-clinical models of CDI, we have identified a subset of neutrophils that are marked by OLFM4 expression as pathogenic determinants of IEC barrier damage after CDI.

Abstract
Background: Immune-mediated diarrhea and colitis (IMDC) frequently develop after treatment with immune checkpoint inhibitors. C-reactive protein (CRP) is a serum inflammatory biomarker used to stratify and monitor disease severity in many inflammatory conditions. However, CRP level is not specific and is widely influenced by various factors non-specific to bowel inflammation. We aimed to study the utility of CRP as a predictor of disease severity and therapy response in IMDC. Methods: We performed a retrospective analysis of patients diagnosed with IMDC who had CRP measured at IMDC onset and after treatment with selective immunosuppressive therapy (SIT: infliximab and vedolizumab), between 01/2016 and 02/2022 at MD Anderson Cancer Center. Patient demographics, clinical characteristics, and IMDC data were collected and analyzed. Results: Our sample of 128 patients had a median age of 67 years; most were white (89.8%); and male (65.6%). Prior to development of IMDC, 15 (11.7%) were initially treated with anti-CTLA-4, 42 (32.8%) with anti-PD-1 or PD-L1, and 71 (55.5%) with a combination of both. We found higher CRP level was associated with higher CTCAE grade of clinical symptoms such as diarrhea (p=0.015), colitis (p=0.013), and endoscopic findings (p=0.016). While CRP levels decreased after IMDC treatment, there was no significant association between CRP levels with clinical remission, endoscopic remission or histologic remission. There also was no significant correlation between CRP level and recurrence of IMDC, or with fecal calprotectin levels. Conclusion: CRP level may be useful to assess initial severity of IMDC, including grade of diarrhea and colitis and degree of endoscopic inflammation. However, CRP is not a robust surrogate biomarker for assessing treatment response or disease recurrence. Despite the reduction of CRP levels observed following IMDC treatment, this finding might be nonspecific and potentially confounded by concurrent clinical factors, such as underlying malignancy, other inflammatory processes, and systemic anti-cancer therapy. Further studies of the role of CRP are warranted in patients with cancer and IMDC.

Abstract
Obesity defined by high body mass index (BMI) has traditionally been associated with gastrointestinal inflammatory processes but has recently been correlated with better survival in patients receiving immune checkpoint inhibitors (ICI). We sought to investigate the association between BMI and immune-mediated diarrhea and colitis (IMDC) outcomes and whether BMI reflects body fat content on abdominal imaging. This retrospective, single-center study included cancer patients with ICI exposure who developed IMDC and had BMI and abdominal computed tomography (CT) obtained within 30 days before initiating ICI from April 2011 to December 2019. BMI was categorized as <25, ≥25 but <30, and ≥30. Visceral fat area (VFA), subcutaneous fat area (SFA), total fat area (TFA: VFA+SFA), and visceral to subcutaneous fat (V/S) ratio were obtained from CT at the umbilical level. Our sample comprised 202 patients; 127 patients (62.9%) received CTLA-4 monotherapy or a combination, and 75 (37.1%) received PD-1/PD-L1 monotherapy. Higher BMIs ≥ 30 were associated with a higher incidence of IMDC than BMIs ≤ 25 (11.4% vs. 7.9%, respectively; p = 0.029). Higher grades of colitis (grade 3-4) correlated with lower BMI (p = 0.03). BMI level was not associated with other IMDC characteristics or did not influence overall survival (p = 0.83). BMI is strongly correlated with VFA, SFA, and TFA (p < 0.0001). Higher BMI at ICI initiation was linked to a higher incidence of IMDC but did not appear to affect outcomes. BMI strongly correlated with body fat parameters measured by abdominal imaging, suggesting its reliability as an obesity index.

Abstract
BACKGROUND Survival is a key metric of the effectiveness of a health system in managing cancer. We set out to provide a comprehensive examination of worldwide variation and trends in survival from brain tumors in adults, by histology. METHODS We analyzed individual data for adults (15-99 years) diagnosed with a brain tumor (ICD-O-3 topography code C71) during 2000-2014, regardless of tumor behavior. Data underwent a 3-phase quality control as part of CONCORD-3. We estimated net survival for 11 histology groups, using the unbiased nonparametric Pohar Perme estimator. RESULTS The study included 556,237 adults. In 2010-2014, the global range in age-standardized 5-year net survival for the most common sub-types was broad: in the range 20%-38% for diffuse and anaplastic astrocytoma, from 4% to 17% for glioblastoma, and between 32% and 69% for oligodendroglioma. For patients with glioblastoma, the largest gains in survival occurred between 2000-2004 and 2005-2009. These improvements were more noticeable among adults diagnosed aged 40-70 years than among younger adults. CONCLUSIONS To the best of our knowledge, this study provides the largest account to date of global trends in population-based survival for brain tumors by histology in adults. We have highlighted remarkable gains in 5-year survival from glioblastoma since 2005, providing large-scale empirical evidence on the uptake of chemoradiation at population level. Worldwide, survival improvements have been extensive, but some countries still lag behind. Our findings may help clinicians involved in national and international tumor pathway boards to promote initiatives aimed at more extensive implementation of clinical guidelines.

Abstract
BACKGROUND The role of diastolic blood pressure (DBP) with cognitive functioning is under-explored in relation to levels of systolic blood pressure (SBP). METHODS We studied 5466 participants from the National Health and Nutrition Examination Survey. Blood pressure was measured 3 times manually with a standardized sphygmomanometer and averaged. Cognitive functioning was measured using the digit symbol substitution test (DSST). RESULTS Participants were 60 years or older, 55% female, and 81% non-Hispanic White. Most participants had a DBP between 70 to <80 mmHg (33.7%), between 60 to <70 mmHg (29.3%), or <60 mmHg (18.8%). From multivariable linear regression analyses, each 5 mmHg increment of DBP was associated with significantly higher DSST scores among individuals with SBP <120 only (ß: 0.56, 95% CI: 0.09, 1.03). CONCLUSIONS Among older US adults, at non-elevated levels of SBP, higher DBP is associated with better cognitive performance.

Abstract
Immune checkpoint blockade (ICB) therapy frequently induces immune-related adverse events. To elucidate the underlying immunobiology, we performed a deep immune analysis of intestinal, colitis, and tumor tissue from ICB-treated patients with parallel studies in preclinical models. Expression of interleukin-6 (IL-6), neutrophil, and chemotactic markers was higher in colitis than in normal intestinal tissue; T helper 17 (Th17) cells were more prevalent in immune-related enterocolitis (irEC) than T helper 1 (Th1). Anti-cytotoxic T-lymphocyte-associated antigen 4 (anti-CTLA-4) induced stronger Th17 memory in colitis than anti-program death 1 (anti-PD-1). In murine models, IL-6 blockade associated with improved tumor control and a higher density of CD4+/CD8+ effector T cells, with reduced Th17, macrophages, and myeloid cells. In an experimental autoimmune encephalomyelitis (EAE) model with tumors, combined IL-6 blockade and ICB enhanced tumor rejection while simultaneously mitigating EAE symptoms versus ICB alone. IL-6 blockade with ICB could de-couple autoimmunity from antitumor immunity.

Our knowledge of GI irAE in patients with luminal GI malignancies is poor. We aimed to characterize the incidence, clinical features, treatment, and outcomes of these GI irAEs. Methods This was a retrospective study of patients with malignancies involving the luminal GI tract and GI irAEs at MD Anderson Cancer Center from January 2010 to June 2020. Clinical data were collected and analyzed. Results Eighteen patients with luminal GI tract malignancies treated with ICIs had evidence of GI irAEs based on clinical symptoms and/or histology. The predominant GI irAE symptom was diarrhea (78%). Ten had non-ulcerative inflammation (56%) and 5 had ulcerative inflammation (28%) on endoscopy. Histologically, 3 patients (17%) had evidence of acute inflammation, 4 (22%) had chronic inflammation, and 9 (50%) had both. Ten patients (56%) received immunosuppressant treatment, which included steroids alone (n=2, 20%), steroids with biologics (infliximab or vedolizumab) (n=7, 70%), or biologics alone (n=1, 10%), with clinical remission in all cases. Of the 6 patients who previously had stable or ICI-responsive cancer and received immunosuppressants, none developed progression of GI luminal malignancy during the study period. Conclusions GI irAEs occurred in 2.4% of patients treated with ICI for cancer involving the luminal GI tract. Immunosuppressant therapies (e.g., vedolizumab) appear to be effective for GI irAEs, showing no association with further GI luminal cancer progression, recurrence, or a subsequent poor response to ICI therapy.

Abstract
Micro/nanostructured surfaces (MNSS) have shown the ability to inactivate bacterial cells by physical means. An enormous amount of research has been conducted in this area over the past decade. Here, we review the various surface factors that affect the bactericidal efficiency. For example, surface hydrophobicity of the substrate has been accepted to be influential on the bactericidal effect of the surface, but a review of the literature suggests that the influence of hydrophobicity differs with the bacterial species. Also, various bacterial viability quantification methods on MNSS are critically reviewed for their suitability for the purpose, and limitations of currently used protocols are discussed. Presently used static bacterial viability assays do not represent the conditions of which those surfaces could be applied. Such application conditions do have overlaying fluid flow, and bacterial behaviours are drastically different under flow conditions compared to under static conditions. Hence, it is proposed that the bactericidal effect should be assessed under relevant fluid flow conditions with factors such as shear stress and flowrate given due significance. This review will provide a range of opportunities for future research in design and engineering of micro/nanostructured surfaces with varying experimental conditions.

Abstract
BACKGROUND Chemopreventive effects of zinc for esophageal cancer have been well documented in animal models. This prospective study explores if a similar, potentially chemopreventive action can be seen in Barrett's esophagus (BE) in humans. AIMS To determine if molecular evidence can be obtained potentially indicating zinc's chemopreventive action in Barrett's metaplasia. METHODS Patients with a prior BE diagnosis were placed on oral zinc gluconate (14 days of 26.4 mg zinc BID) or a sodium gluconate placebo, prior to their surveillance endoscopy procedure. Biopsies of Barrett's mucosa were then obtained for miRNA and mRNA microarrays, or protein analyses. RESULTS Zinc-induced mRNA changes were observed for a large number of transcripts. These included downregulation of transcripts encoding proinflammatory proteins (IL32, IL1β, IL15, IL7R, IL2R, IL15R, IL3R), upregulation of anti-inflammatory mediators (IL1RA), downregulation of transcripts mediating epithelial-to-mesenchymal transition (EMT) (LIF, MYB, LYN, MTA1, SRC, SNAIL1, and TWIST1), and upregulation of transcripts that oppose EMT (BMP7, MTSS1, TRIB3, GRHL1). miRNA arrays showed significant upregulation of seven miRs with tumor suppressor activity (-125b-5P, -132-3P, -548z, -551a, -504, -518, and -34a-5P). Of proteins analyzed by Western blot, increased expression of the pro-apoptotic protein, BAX, and the tight junctional protein, CLAUDIN-7, along with decreased expression of BCL-2 and VEGF-R2 were noteworthy. CONCLUSIONS When these mRNA, miRNA, and protein molecular data are considered collectively, a cancer chemopreventive action by zinc in Barrett's metaplasia may be possible for this precancerous esophageal tissue. These results and the extensive prior animal model studies argue for a future prospective clinical trial for this safe, easily-administered, and inexpensive micronutrient, that could determine if a chemopreventive action truly exists.

Abstract
Background:Idiopathic inflammatory myositis (IIM) are a heterogeneous group of immune-mediated disorders with varied presentations and multiple organ involvement. Data on long term outcome among South Asian patients with IIM is sparse.Objectives:To study the long term clinical outcome, treatment responses and factors predicting outcome among adult patients with IIMMethods:Patients diagnosed as ‘Idiopathic Inflammatory Myositis’ under the department of Clinical Immunology and Rheumatology at CMC, Vellore, India were screened retrospectively. Patients aged 18 years and above, satisfying Bohan and Peter criteria, having follow up of one year or more with atleast two outpatient or inpatient visits between January 2010 and April 2019 were included in this study. Those patients with connective tissue disease associated myositis were not included. Details on muscle weakness, extramuscular involvement, muscle enzymes and treatment administered were recorded at baseline, 3, 6, 12, 18, 24 months and yearly thereafter. After assessing their cumulative response, categorization of patients into complete and partial responders was done. Complete responders were defined as patients with persistent muscle power of more than 4/5 and/or MMT 8 more than 76/80, complete resolution of skin, articular and lung involvement (if any) as well as muscle enzymes less than twice the upper limit of normal without any documented flares during the entire follow up period. Patients not satisfying the said criterias were grouped as Partial responders. Disease free survival duration was also analyzed.Results:Out of 310 patients of IIM identified, 187 (60.3%) patients satisfied the inclusion criteria. Women were 2.2 times more than men and mean age at symptom onset was 35.7±12.6 years. Dermatomyositis was the predominant myositis subtype seen. All patients were put on steroids with the mean dose being 45.9 ± 18.6 mg/day. At baseline, the key immunosuppressants used were methotrexate in 44.9% and mycophenolate in 37.6% patients. The median follow up duration was 48 (25-80) months. An associated malignancy was diagnosed in 3.2% after a median duration of 24.5 months. Five patients expired after a median duration of 80 months from diagnosis. Normal muscle power was attained in 76.1% patients and 88.6% were vocational by the last follow up visit. Steroids were discontinued in 56.7% patients after a median duration of 24 months (p=0.0002). Discontinuation of the immunosuppressant was feasible in 10.2% patients after a median duration of 44 months. Assessment of the cumulative responses revealed a relapsing and remitting course in 45.9%. Outcome predictors in univariate analysis were Jo-1 status, presence of arthritis, interstitial lung disease and pericardial effusion at baseline. On multivariate analysis, absence of pericardial effusion (p=0.011) and interstitial lung disease (p=0.067) at baseline were found to be predictors of complete response. Disease free survival probability estimated at 5 years and 10 years was 91.6% and 72.4% respectively. Estimating the probability gender wise, males achieved disease free status earlier than females.Conclusion:A favorable clinical and functional outcome was seen in a significant proportion of these patients with IIM on long term follow up. Pericardial effusion and ILD were identified as predictors of poor clinical outcome.References:[1]Taborda AL, Azevedo P, Isenberg DA.

Abstract
Background:Anti-phospholipid syndrome (APS) is an important cause for recurrent pregnancy losses (RPL). Conventional APS antibodies (aPLs) like lupus anti-coagulant (LA), anti-cardiolipin(ACL) and anti-beta 2 glycoprotein I (anti-β2 GP I) are not present in significant number of obstetric APS(OAPS) patients, leading to a state described as “ sero-negative” OAPS (SNOAPS). Recent literature shows non-conventional aPLs like Anti phosphatidylserine-prothrombin complex (Anti-PSPT) and Anti-Annexin V (Anti-Ann V) can be positive in up to 50% of SNOAPS patientsObjectives:Testing the performance of conventional and non-conventional aPLs in suspected OAPS patients (obstetric events as defined in the Sydney classification criteria for APS)Methods:We performed a retrospective chart review of 101 patients who underwent combined testing for non-conventional aPLs for suspected OAPS from May 2016 to November 2019 at our department. Patients were categorized into OAPS cases (n=50, median age 31 years) and controls (n=51, median age 30 years) based on their fulfillment of clinical definition of OAPS events defined by Sydney criteria. Conventional aPLs were tested by methods adapted in Sydney criteria and Anti PSPT /Anti Ann V were tested by commercial ELISA. The sample size(n=101) has 95% confidence interval with a margin of error of 10% for the objective of the study.Results:36 cases (72%) were ‘sero-positive’ & 14 cases (28%) were truly ‘sero-negative’ for conventional aPLs. 5 (35.7%) of the SNOAPS patients were positive for Ant-PSPT and/or Anti AnnV antibodies. Performance of the various aPLs in suspected OAPS is displayed in Table 1 & Figure 1.Table 1showing the performance of the various conventional and non-conventional APLs in suspected obstetric APS casesAntibodySensitivitySpecificityLikelihood Ratio(+)Likelihood Ratio (-)Positive Predictive ValueNegative Predictive ValueAccuracyYouden’s IndexLA50%94.1 %8.50.589.3%65.7%72.3%44.1%ACL32%98%16.30.794.1%59.5 %65.3%30 %anti β2 GP I IgM38.4%91.4 %4.50.783.3%57.1 %63.5%29.8%anti β2 GP I IgG24%96.1 %6.10.885.7%56.3%60.4%20.1%Anti PSPT28%96.1 %7.10.787.5%57.6 %62.4%24.1%Anti AnnV28%98 %14.30.793.3%58.1%63.4%26%Conventional APLs72%88.2%6.10.385.7%76.3 %79.8%60.2%Non-conventional APLS38%94.1%6.40.786.4%60.7 %66.3%32.1%All APLs82%86.3%6.000.2085.4%83 %84.2%68.3%Figure 1showing the comparative diagnostic performance of Conventional aPL testing vs Combined testing along with non-conventional aPLs in suspected obstetric APS scenarioConclusion:In a delicate situation like RPL, performance of non-conventional aPLs on their own, though not as sensitive as conventional aPLs, still demonstrate better specificity. Non-conventional APLs can newly identify 1/3rd of SNOAPS as APS. The real value of testing Anti PSPT & Anti Ann V in RPL, is combined testing with conventional aPLs wherein they improve the sensitivity and accuracy of diagnosis of OAPS by 10% & 4.4 % respectively, with only 1.9% drop in specificity. Non-conventional aPLs should be tested in SNOAPS.Disclosure of Interests:None declared

Abstract
Background:Physical function is a core domain to be measured in randomized controlled trials (RCTs) of psoriatic arthritis (PsA). The discriminative performance of patient reported outcome measures (PROMs) for physical function (PF) in RCTs has not been evaluated systematically.Objectives:In this systematic review, the GRAPPA-OMERACT working group aimed to evaluate the clinical trial discrimination of PF-PROMs in PsA RCTs.Methods:We searched PubMed and Scopus databases in English to identify all original RCTs conducted in PsA. We limited the review to RCTs of biologic and targeted synthetic DMARDs. Groups of two researchers extracted data independently for PF-PROMs. We assessed quality in each article using the OMERACT good method checklist. Effect sizes (ES) for the PF-PROMs were calculated and appraised usinga priorihypotheses. Evidence supporting clinical trial discrimination for each PF-PROM was summarized to derive recommendations.Results:32 articles were included (Figure 1). Four PF-PROMs had data for evaluation: HAQ-Disability Index (DI), HAQ-Spondyloarthritis (S), Short Form 36-item Health Survey Physical Component Summary (SF-36 PCS), and the Physical Functioning domain (SF-36 PF) (Table 1). The ES for intervention versus (vs.) control arms for HAQ-DI ranged from -0.55 to -1.81 vs. 0.24 to -0.52; and for SF-36 PCS ranged from 0.30 to 1.86 vs. -0.02 to 0.63.Table 1.Summary of Measurement Properties Table for clinical trial discriminationArticlesHAQ-DIHAQ-SSF-36 PCSSF-36 PFAntoni 2005 (IMPACT); Gottlieb 2009 (UST)+Antoni 2005 (IMPACT2)++Kavanaugh 2006 (IMPACT2)+Mease 2005 (ADEPT); Genovese 2007 (ADA); Mease 2010 (ETN); Kavanaugh 2009 (GO-REVEAL); Kavanaugh 2017 (GO-VIBRANT); Gladman 2014 (RAPID-PsA); Mease 2015 (FUTURE1); McInnes 2015 (FUTURE2); Kavanaugh, 2016 (FUTURE2)-subgroup; Nash 2018 (FUTURE3); Mease 2017 (SPIRIT-P1); Nash 2017 (SPIRIT-P2); Deodhar 2018 (GUS); Mease 2016 (CLZ)++Mease 2000 (ETN); McInne, 2013 (PSUMMIT 1); Ritchlin 2014 (PSUMMIT 2); Araugo 2019 (ECLIPSA)++Gniadecki 2012 (PRESTA)+Mease 2019 (SEAM-PsA)+/-+McInnes 2014 (SEC)++Mease 2014 (BRO)++Mease 2011 (ABT)+/-+Mease 2017 (ASTRAEA)++Mease 2006 (ALC)+/-Mease 2017 (OPAL Broaden); Gladman 2017 (OPAL Beyond)++Mease 2018 (EQUATOR)++Mease 2018 (ABT-122)+Total available articles311244Total articles for evidence synthesis291232Overall rating+++Color code in each box indicate study quality by OMERACT good methods.

Abstract
AIM India contributes towards a large part of the worldwide epidemic of diabetes and its associated complications. However, there are limited longitudinal studies available in India to understand the occurrence of diabetes complications over time. This pan-India longitudinal study was initiated to assess the real-world outcomes of diabetes across the country. METHODS The LANDMARC study is the first prospective, multicentre, longitudinal, observational study investigating a large cohort of people with type 2 diabetes mellitus across India over a period of 3 years. The primary objective of this ongoing study is to determine the proportion of people developing macrovascular diabetes complications over the duration of the study (36 months ± 45 days) distributed over seven visits; the secondary objective is to evaluate microvascular diabetes complications, glycaemic control and time-to-treatment adaptation or intensification. Overall, 6300 participants (aged 25-60 years) diagnosed with type 2 diabetes for at least 2 years will be included from 450 centres across India. Data will be recorded for baseline demographics, comorbidities, glycaemic measurements, use of anti-hyperglycaemic medications and any cardiovascular or other diabetes-related events occurring during the observational study period. CONCLUSIONS The LANDMARC study is expected to reveal the trends in complications associated with diabetes, treatment strategies used by physicians, and correlation among treatment, control and complications of diabetes within the Indian context. The findings of this study will help to identify the disease burden, emergence of early-onset complications and dose titration patterns, and eventually develop person-centred care and facilitate public health agencies to invest appropriate resources in the management of diabetes.

Abstract
Myocardial infarction (MI) is a relatively common medical condition in the community. A rare complication of acute MI is left ventricular rupture (LV) rupture. This usually follows a transmural infarct. The incidence of this is 2%-4% and this usually happens within 3-7 days of MI. The anterolateral wall is involved in the majority of cases. Atypical presentations can occur several weeks after the initial event. Symptoms may mimic gastrointestinal disorder. The prognosis of this condition is very grim. However, with appropriate treatment, they can make an excellent recovery. The definitive treatment for this is surgical repair. We present the case of a 70-year-old man who had LV rupture and his clinical journey.

Abstract
Abstract
Introduction
In 2014-15, 2.5 million patients over 75 years old underwent surgery compared to 1.5 million in 2006-7. The population is aging with increasing numbers of comorbidities, and associated frailty.1 The Royal College of Anaesthetists recommends that preoperative assessment for these complex older patients takes a “cross-specialty approach.”2 In Colchester the COPES clinic has been introduced in which selected high-risk patients are seen by a Consultant Anaesthetist and Consultant Geriatrician. This aims to medically optimise patients prior to surgery and to facilitate shared decision making.
Methods
The new clinic was introduced in October 2018. The following data was collected from COPES clinic letters from October to February 2018-19 (n=46):Patient/ surgery characteristics: age, comorbidities, frailty score and any cognitive impairmentInterventions: changes to medication, specialty referral, intravenous iron, diabetes optimisation, otherOutcomes of surgery following the COPES clinic
Patients were asked to complete feedback forms to evaluate the service.
Results
52% of patients had 4-6, and 28% had 7-9 comorbidities. The majority had Rockwood frailty scores of 4 or 5. 28% of patients had medications changed, 48% had specialty referrals, 17% received intravenous iron, 8.7% required diabetes optimisation and 28% of patients had investigations including echocardiograms, MRI and CT scans. 12/46 patients had surgery deemed unlikely to go ahead after shared decision making with patients in conjunction with the multidisciplinary team involved in their care. 2 patients died of their comorbidities after deciding not to proceed with surgery. 12/46 patients underwent surgery; 4 developed post-operative complications, none died and the mean length of stay was 3.38 days. The remaining 22/46 patients are awaiting surgery. Patient feedback questionnaires (n=10) were overwhelmingly positive. Everyone felt that they were treated with respect and that their fears were addressed and they were clear in the next steps in management.
Conclusions
The introduction of the ‘COPES’ clinic has helped address frailty and multiple comorbidities by optimising patients’ medical conditions and allowing alternatives to surgery to be considered. Patients were very satisfied with the COPES clinic and felt it has prepared them for upcoming surgery.

Abstract
Background Estrogen receptor-positive (ER-positive) metastatic breast cancer is often intractable due to endocrine therapy resistance. Although ESR1 promoter switching events have been associated with endocrine-therapy resistance, recurrent ESR1 fusion proteins have yet to be identified in advanced breast cancer. Patients and methods To identify genomic structural rearrangements (REs) including gene fusions in acquired resistance, we undertook a multimodal sequencing effort in three breast cancer patient cohorts: (i) mate-pair and/or RNAseq in 6 patient-matched primary-metastatic tumors and 51 metastases, (ii) high coverage (>500×) comprehensive genomic profiling of 287-395 cancer-related genes across 9542 solid tumors (5216 from metastatic disease), and (iii) ultra-high coverage (>5000×) genomic profiling of 62 cancer-related genes in 254 ctDNA samples. In addition to traditional gene fusion detection methods (i.e. discordant reads, split reads), ESR1 REs were detected from targeted sequencing data by applying a novel algorithm (copyshift) that identifies major copy number shifts at rearrangement hotspots. Results We identify 88 ESR1 REs across 83 unique patients with direct confirmation of 9 ESR1 fusion proteins (including 2 via immunoblot). ESR1 REs are highly enriched in ER-positive, metastatic disease and co-occur with known ESR1 missense alterations, suggestive of polyclonal resistance. Importantly, all fusions result from a breakpoint in or near ESR1 intron 6 and therefore lack an intact ligand binding domain (LBD). In vitro characterization of three fusions reveals ligand-independence and hyperactivity dependent upon the 3' partner gene. Our lower-bound estimate of ESR1 fusions is at least 1% of metastatic solid breast cancers, the prevalence in ctDNA is at least 10× enriched. We postulate this enrichment may represent secondary resistance to more aggressive endocrine therapies applied to patients with ESR1 LBD missense alterations. Conclusions Collectively, these data indicate that N-terminal ESR1 fusions involving exons 6-7 are a recurrent driver of endocrine therapy resistance and are impervious to ER-targeted therapies.

Abstract
A custom-built mask aligner (CBMA), which fundamentally covers all the key features of a commercial mask aligner, while being low cost and light weight and having low power consumption and high accuracy, is constructed. The CBMA is composed of a custom high fidelity light emitting diode light source, a vacuum chuck, a mask holder, high-precision translation and rotation stages, and high resolution digital microscopes. The total cost of the system is under $7500, which is over ten times cheaper than a comparable commercial system. It produces a collimated ultraviolet illumination of 1.8-2.0 mW cm-2 over an area of a standard 4-in. wafer, at the plane of photoresist exposure, and the alignment accuracy is characterized to be <3 μm, which is sufficient for most microfluidic applications. Moreover, this manuscript provides detailed descriptions of the procedures needed to fabricate multilayered master molds using our CBMA. Finally, the capabilities of the CBMA are demonstrated by fabricating two- and three-layer masters for micro-scale devices, commonly encountered in biomicrofluidic applications. The former is a flow-free chemical gradient generator, and the latter is an addressable microfluidic stencil. Scanning electron microscopy is used to confirm that the master molds contain the intended features of different heights.

Abstract
Preoperative CEA and CA 19–9 levels have been used in the past as prognostic indicators in colorectal cancer, but Dukes’ stage is still considered to be the most important prognostic factor. Recent survival estimates may have been influenced by the fact that in the last decade adjuvant chemotherapy and postoperative irradiation have been included in the routine management of advanced-stage disease. In a heterogeneous Kuwaiti population higher reference levels (95th percentile) of CEA and CA 19–9 have been found than those usually employed. In the present study 62 patients with Dukes’ stage B + C could be analyzed for two-year disease-free survival (DFS). Relapse was observed in 19 patients, 28 patients were disease free and 15 patients with censored observations were included. No significant difference in DFS was observed in Dukes’ B (69%) versus Dukes’ C (48%) patients (p=0.09). On the other hand, Dukes’ stage B+C patients with elevated preoperative levels of CEA or CA 19–9 had a significantly poorer DFS than patients with normal levels. For CEA levels below or above the cutoff the DFS was 74% versus 23% (p=0.003); for CA 19–9 levels below or above the cutoff the DFS was 71% versus 33% (p=0.004). In 54 patients with Dukes’ stage B+C for whom preoperative levels of both CEA and CA 19–9 were available multivariate analysis revealed a decreasing risk of relapse in the following order: CEA and/or CA 19–9 elevated (chi-square 7.09; p=0.008), CA 19–9 elevated (chi-square 6.27; p=0.01), CEA elevated (chi-square 5.47; p=0.02), and Dukes’ C (chi-square 2.08; p=0.15 n.s.). Hence, novel treatment protocols may have improved the disease-free survival, but the use of adjuvant chemotherapy and/or radiotherapy is of questionable benefit in patients who have elevated levels of CEA and/or CA 19–9 prior to treatment.

Abstract
The tumor markers CEA, CA 19-9, CA 72-4 and CYFRA 21-1 were analyzed in a group of apparently healthy subjects (n=232) in Kuwait using the ®Elecsys Relecsys 1010 analyzer. The distribution of the tumour marker levels was analyzed separately in Kuwaitis (n=103), non-Kuwaitis (n=129), smokers (n=68), non-smokers (n=164), males (n=138) and females (n=94). The distribution of CEA was significantly different in Kuwaitis vs. non-Kuwaitis in the total population (p=0.033) and in non-smokers (p=0.049); in males vs. females in the total population (p<0.0001) and in non-smokers (p=0.0002); and in smokers vs. non-smokers in the total population (p<0.0001) using the non-parametric Mann-Whitney U test. None of the other tumour markers showed significant differences in the subgroups. The upper reference level was defined as the 95th percentile of the normal values in each group. A higher reference level of CEA was observed in smokers (vs. non-smokers) in the total population. Also higher reference levels of CEA were observed in males (vs. females) both in the total population and in non-smokers. In the total population the respective reference levels were: CEA: 4.4 μg/L, CA 19-9: 35 kU/L, CA 72.4: 2.4 kU/L, and CYFRA 21.1: 2.1 μg/L. These results were compared with data in the kit inserts and literature data. The impact of 95th percentiles in a local heterogeneous population is discussed.

Abstract
Suspicion and subsequent detection of renal disease is by an assessment of the urinalysis and renal function in the clinical context. Our attempt in this study is to correlate initial presenting features of urinalysis and renal function to the final histopathological diagnosis. A retrospective analysis of 1059 native kidney biopsies performed from January 2002 to June 2015 at Amrita Institute of Medical Sciences was conducted. Correlative patterns between urinalysis, renal function, and final histopathological diagnosis were studied. Five hundred and eleven (48%) patients had nephrotic syndrome. Out of these, 193 (38%) had pure: nephrotic syndrome, 181 (35.8%) had associated microhematuria, 110 (21.7%) had microhematuria and renal failure, and 27 (5.3%) had only associated renal failure. Minimal change disease (MCD) (30%), membranous nephropathy (30%), and IgA nephropathy (29%) were the major diseases in the respective groups. Five hundred and five (47.6%) patients had subnephrotic proteinuria. Out of these, 29 (5.6%) had only subnephrotic proteinuria, 134 (27%) had additional microhematuria, 300 (59%) had subnephrotic proteinuria, microhematuria, and renal failure, and 42 (8%) had subnephrotic proteinuria with renal failure. Lupus Nephritis (45% and 40%) and IgA Nephropathy (32% and 21%) were the major disorders in the subgroups respectively. Forty-two patients (3.7%) were biopsied for isolated renal failure with bland urinary sediment. Cast nephropathy and acute interstitial nephritis were the major diseases. Out of 89 patients with diabetes who were biopsied, 15 (16.8%) had diabetic nephropathy, 45 (50.5%) had no diabetic nephropathy, and 29 (32.5%) had diabetic nephropathy along with a non-diabetic renal disease. Postinfectious glomerulonephritis was the major glomerular disease. IgA nephropathy (22.2%) and membranous nephropathy (15.5%) were the major diseases in patients with diabetes with no diabetic nephropathy. In our population, MCD and membranous nephropathy formed the majority of diseases in biopsied nephrotic syndrome. Added microhematuria did not seem to decrease the incidence of either disease on the whole. We found a significant number of patients with membranous nephropathy with nephrotic syndrome, microhematuria, and additional renal failure. IgA nephropathy formed a majority of cases with nephrotic syndrome, microhematuria, and renal failure. The presence of renal failure regardless of other abnormalities in urinalysis showed a trend toward IgA nephropathy. Membranous nephropathy may have a more varied presentation than was originally thought and IgA nephropathy presenting as nephrotic syndrome may not be uncommon. MCD is the major subgroup of diseases in the pediatric population and presents both as nephrotic syndrome as well as nephrotic syndrome with microhematuria. Thus, urinalysis and renal failure may be a valuable tool in assessing renal disease.

Abstract
More efficacious treatment regimens are needed for tuberculosis, however, drug development is impeded by a lack of reliable biomarkers of disease severity and of treatment effect. We conducted a directed screen of host biomarkers in participants enrolled in a tuberculosis clinical trial to address this need. Serum samples from 319 protocol-correct, culture-confirmed pulmonary tuberculosis patients treated under direct observation as part of an international, phase 2 trial were screened for 70 markers of infection, inflammation, and metabolism. Biomarker assays were specifically developed for this study and quantified using a novel, multiplexed electrochemiluminescence assay. We evaluated the association of biomarkers with baseline characteristics, as well as with detailed microbiologic data, using Bonferroni-adjusted, linear regression models. Across numerous analyses, seven proteins, SAA1, PCT, IL-1β, IL-6, CRP, PTX-3 and MMP-8, showed recurring strong associations with markers of baseline disease severity, smear grade and cavitation; were strongly modulated by tuberculosis treatment; and had responses that were greater for patients who culture-converted at 8weeks. With treatment, all proteins decreased, except for osteocalcin, MCP-1 and MCP-4, which significantly increased. Several previously reported putative tuberculosis-associated biomarkers (HOMX1, neopterin, and cathelicidin) were not significantly associated with treatment response. In conclusion, across a geographically diverse and large population of tuberculosis patients enrolled in a clinical trial, several previously reported putative biomarkers were not significantly associated with treatment response, however, seven proteins had recurring strong associations with baseline radiographic and microbiologic measures of disease severity, as well as with early treatment response, deserving additional study.

Abstract
BACKGROUND Lung cancer most commonly presents in advanced stages in developing countries, where combined modality treatment using chemo-radiotherapy (CTRT) is the standard of care. MATERIALS AND METHODS A retrospective audit of patients of nonsmall cell lung cancer (NSCLC) treated at a single Institute from January 2008 to December 2012 was conducted. Various prognostic factors affecting disease-free survival (DFS) and overall survival (OS) were studied by univariate and multivariate analysis. All patients were meticulously followed-up clinically and telephonic contacts. RESULTS Overall 171 patients of NSCLC were treated with definitive CTRT using concurrent chemotherapy in 66% patients and sequential therapy in 28% patients. The actuarial 2 years DFS was 17.5% and 2 years OS was 61.5%. Complete response to treatment resulted in significantly better DFS and OS. Definitive CTRT was very well-tolerated in these patients with good compliance. CONCLUSION Definitive CTRT, sequence being individualized depending on performance status and disease stage at presentation, is a feasible and effective treatment modality for locally advanced NSCLC patients in the developing world. Response to treatment is an important prognostic factor for treatment outcomes.

Abstract
This study was planned to analyze the hemodialysis practice patterns from a tertiary care referral centre as there is very limited data from India. All patients of ESRD on maintenance hemodialysis (MHD) in dialysis unit at AIMS, Kochi, Kerala for a minimum period of 3 months were included. A total of 134 patients (M: F 2:1) with age of 20 to 84 years (Mean: 59.83; SD: 11.98) were studied. The most common causes of ESRD in study population were diabetic nephropathy (DN) (59.7%) followed by unclassified group (19.4%), chronic glomerulonephritis (CGN) (11.9%). Majority (81%) were initiated on MHD through temporary vascular access on emergency basis. Majority (79%) of the patients were on twice weekly MHD. The range of eGFR (ml/min/1.73 m2) at the time of initiation of MHD was 1.26-11.78 by CG formula and 2.18-16.4 by MDRD equation. The mean duration on hemodialysis was 37.16 months and 50.7% patients had died during the follow-up period (3-108 months). The mean survival time on hemodialysis was 40.31 months (SD = 26.69). The mean survival time was lower in diabetic nephropathy (35.93 months) than in non-diabetic renal disease (47.46 months). The most common causes of deaths were cardiovascular events (51.5%), and infections (26.5%). In conclusion, males outnumbered females, among those on hemodialysis. There was no significant difference in eGFR at initiation of MHD based on etiologies. Initiation of MHD via temporary access, presence of LVH, acute coronary syndrome, use of acetate dialysate, need for parenteral iron therapy had impact on mortality. Survival rates while on hemodialysis at end 1st, 3rd, 5th and 7th years were 87.31, 45.52, 21.64 and 7.46 percentages respectively.

Abstract
Killer immunoglobulin-like receptors (KIRs) interact with human leucocyte antigen (HLA) class I ligands and play a key role in the regulation and activation of NK cells. The functional importance of KIR-HLA interactions has been demonstrated for a number of chronic viral infections, but to date only a few studies have been performed in the context of acute self-limited viral infections. During our investigation of CD8(+) T cell responses to a conserved HLA-B57-restricted epitope derived from dengue virus (DENV) non-structural protein-1 (NS1), we observed substantial binding of the tetrameric complex to non-T/non-B lymphocytes in peripheral blood mononuclear cells (PBMC) from a long-standing clinical cohort in Thailand. We confirmed binding of the NS1 tetramer to CD56(dim) NK cells, which are known to express KIRs. Using depletion studies and KIR-transfected cell lines, we demonstrated further that the NS1 tetramer bound the inhibitory receptor KIR3DL1. Phenotypical analysis of PBMC from HLA-B57(+) subjects with acute DENV infection revealed marked activation of NS1 tetramer-binding natural killer (NK) cells around the time of defervescence in subjects with severe dengue disease. Collectively, our findings indicate that subsets of NK cells are activated relatively late in the course of acute DENV illness and reveal a possible role for specific KIR-HLA interactions in the modulation of disease outcomes.
