Objective At least half of patients with systemic lupus erythematosus (SLE) develop organ damage as a consequence of autoimmune disease or long-term therapeutic steroid use. This study synthesised evidence on the association between organ damage and mortality in patients with SLE. Design Systematic review and meta-analysis. Methods Electronic searches were performed in PubMed, Embase, Cochrane Library and Latin American and Caribbean Health Sciences Literature for observational (cohort, case-control and cross-sectional) studies published between January 2000 and February 2017. Included studies reported HRs or ORs on the association between organ damage (measured by the Systemic Lupus International Collaborating Clinics/American College of Rheumatology Damage Index (SDI) score) and mortality. Study quality was assessed using the modified Newcastle-Ottawa assessment. Pooled HRs were obtained using the DerSimonian and Laird random-effects model. Heterogeneity was assessed using the Cochrane Q (Q) and I2 statisti and decrease mortality for patients with SLE.Over the past 5 years, several studies have begun to uncover the links between the classical signal transduction pathways and the physical mechanisms that are used to sculpt branched tissues. These advances have been made, in part, thanks to innovations in live imaging and reporter animals. With modern research tools, our conceptual models of branching morphogenesis are rapidly evolving, and the differences in branching mechanisms between each organ are becoming increasingly apparent. Here, we highlight four branched epithelia that develop at different spatial scales, within different surrounding tissues and via divergent physical mechanisms. Each of these organs has evolved to employ unique branching strategies to achieve a specialized final architecture.Healthcare professionals' capacity to protect themselves, while caring for infected patients during an infectious disease pandemic, depends on their ability to practise universal precautions. https://www.selleckchem.com/ In turn, universal precautions rely on the availability of personal protective equipment (PPE). During the SARS-CoV2 outbreak many healthcare workers across the globe have been reluctant to provide patient care because crucial PPE components are in short supply. The lack of such equipment during the pandemic was not a result of careful resource allocation decisions in the global north, where the short supply could be explained through their high cost. Instead, they were the result of democratically elected governments prioritising low tax regimes over an adequate resourcing of their healthcare delivery systems. Such decisions were made despite global health experts warning about the high probability of pandemics like SARS-CoV2 occurring during our lifetimes. Avoidable allocation decisions by democratically elected political leaders resulted in a lack of sufficient PPE for healthcare professionals. After discussing and discounting various ethical arguments in support of a professional obligation to treat, even without or with suboptimal PPE, I conclude that these policy decisions were sufficiently grave that they provide a sound ethical rationale to justify healthcare workers' refusal to provide care to infected patients.Objective To refine and validate a model for predicting the risk of gastrointestinal (GI) cancer in iron deficiency anaemia (IDA) and to develop an app to facilitate use in clinical practice. Design Three elements (1) analysis of a dataset of 2390 cases of IDA to validate the predictive value of age, sex, blood haemoglobin concentration (Hb), mean cell volume (MCV) and iron studies on the probability of underlying GI cancer; (2) a pilot study of the benefit of adding faecal immunochemical testing (FIT) into the model; and (3) development of an app based on the model. Results Age, sex and Hb were all strong, independent predictors of the risk of GI cancer, with ORs (95% CI) of 1.05 per year (1.03 to 1.07, p less then 0.00001), 2.86 for men (2.03 to 4.06, p less then 0.00001) and 1.03 for each g/L reduction in Hb (1.01 to 1.04, p less then 0.0001) respectively. An association with MCV was also revealed, with an OR of 1.03 for each fl reduction (1.01 to 1.05, p less then 0.02). The model was confirmed to be robust by an internal validation exercise. In the pilot study of high-risk cases, FIT was also predictive of GI cancer (OR 6.6, 95% CI 1.6 to 51.8), but the sensitivity was low at 23.5% (95% CI 6.8% to 49.9%). An app based on the model was developed. Conclusion This predictive model may help rationalise the use of investigational resources in IDA, by fast-tracking high-risk cases and, with appropriate safeguards, avoiding invasive investigation altogether in those at ultra-low predicted risk.The adaptor protein ASC (apoptosis-associated speck-like protein containing a CARD) is known to facilitate caspase-1 activation, which is essential for innate host immunity via the formation of the inflammasome complex, a multiprotein structure responsible for processing IL1β and IL18 into their active moieties. Here, we demonstrated that ASC-deficient CD8+ T cells failed to induce severe graft-versus-host disease (GVHD) and had impaired capacity for graft rejection and graft-versus-leukemia (GVL) activity. These effects were inflammasome-independent because GVHD lethality was not altered in recipients of caspase-1/11-deficient T cells. We also demonstrated that ASC deficiency resulted in a decrease in cytolytic function, with a reduction in granzyme B secretion and CD107a expression by CD8+ T cells. Altogether, our findings highlight that ASC represents an attractive therapeutic target for improving outcomes of clinical transplantation.Background and purpose Tobacco use is declining but the use of electronic nicotine delivery systems (ENDS) has increased in young populations. The Interdisciplinary Tobacco Use Research Program (ITURP) developed a survey assessing tobacco and ENDS use, and a tobacco-free campus policy. This project analyzes the reliability and validity of the Tobacco Attitude and Behavior Survey (TABS). Methods Content and face validity, factor analysis, Cronbach's Alpha, and a process evaluation were assessed. Results Factor analysis revealed four constructs. Cronbach's alpha was .70. Process evaluation revealed that students involvement in TABS allowed rapid assessment of changes in ENDS use, and to modify questions based on student feedback. Conclusion Reliability and validity are adequate for a new tool.Objectives The transition from hospital to home is a period of risk, particularly for children with medical complexity. Our aim was to identify and address discharge challenges through execution of postdischarge phone calls. Methods In this prospective study, we designed and executed a postdischarge phone call for patients discharged from an inpatient complex care team between May and November 2018. The call included dichotomous and open-ended questions to identify challenges regarding health status, follow-up appointments, medications, home nursing, medical supplies and/or equipment, and discharge instructions. These were recorded in the electronic health record. Details regarding identified challenges and corrective actions were categorized by 2 reviewers and adjudicated by a third reviewer if disagreement occurred. Results Descriptive statistics were used to summarize these findings. Sixty-seven phone calls were completed within 1 week of discharge. Two-thirds of calls identified at least 1 challenge, and more than one-third of calls identified 2 or more challenges for a total of 90 challenges. The most common challenges involved health status (26.7%), follow-up appointments (21.1%), and medications (20%). The majority of challenges were addressed by either caregivers or the multidisciplinary team, with the exception of home nursing challenges. Conclusions Discharge challenges were commonly identified by caregivers of children with medical complexity. The majority of postdischarge challenges were addressed, with some addressed by families themselves. These results can inform health care providers about challenges to anticipate and suggest future interventions to mitigate anticipated challenges for a safe discharge and transition of care for these at-risk patients.Most antigenic peptides that bind stably to a major histocompatibility complex (MHC) I molecule for display to the immune system are approximately the same length, thanks in part to the expert trimming done by endoplasmic reticulum aminopeptidases (ERAPs), the final peptidases in the antigen-presentation pathway. An open question is whether ERAPs edit peptides to this optimal length while they are bound to MHC I molecules (using the latter as a pattern of sorts) or by free hand. Mavridis et al. present multiple lines of evidence that this trimming cannot readily occur on MHC I molecules, but rather only in solution, suggesting that ERAPs work alone to tailor the perfect fit for the immunopeptidome.Purpose Genomic methods can identify homologous recombination deficiency (HRD). Rigorous evaluation of their outcome association to DNA damage response-targeted therapies like platinum in pancreatic ductal adenocarcinoma (PDAC) is essential in maximizing therapeutic outcome. Experimental design We evaluated progression-free survival (PFS) and overall survival (OS) of patients with advanced-stage PDAC, who had both germline- and somatic-targeted gene sequencing. Homologous recombination gene mutations (HRm) were evaluated BRCA1, BRCA2, PALB2, ATM, BAP1, BARD1, BLM, BRIP1, CHEK2, FAM175A, FANCA, FANCC, NBN, RAD50, RAD51, RAD51C, and RTEL1 HRm status was grouped as (i) germline versus somatic; (ii) core (BRCAs and PALB2) versus non-core (other HRm); and (iii) monoallelic versus biallelic. Genomic instability was compared using large-scale state transition, signature 3, and tumor mutation burden. Results Among 262 patients, 50 (19%) had HRD (15% germline and 4% somatic). Both groups were analyzed together due to lack of difference in their genomic instability and outcome. Median [95% confidence interval (CI)] follow-up was 21.9 (1.4-57.0) months. Median OS and PFS were 15.5 (14.6-19) and 7 (6.1-8.1) months, respectively. Patients with HRD had improved PFS compared with no HRD when treated with first-line (1L) platinum [HR, 0.44 (95% CI 0.29-0.67); P less then 0.01], but not with 1L-non-platinum. Multivariate analysis showed HRD patients had improved OS regardless of their first-line treatment, but most had platinum exposure during their course. Biallelic HRm (11%) and core HRm (12%) had higher genomic instability, which translated to improved PFS on first-line platinum (1L-platinum) versus 1L-non-platinum. Conclusions Pathogenic HRm identifies HRD in patients with PDAC with the best outcome when treated with 1L-platinum. Biallelic HRm and core HRm further enriched benefit from 1L-platinum from HRD.Background PARP inhibitors (PARPis) are standard-of-care therapy for high-grade serous ovarian cancer (HGSOC). We investigated combining cediranib (antiangiogenic) with olaparib (PARPi) at emergence of PARPi resistance. Methods The proof-of-concept EVOLVE study (NCT02681237) assessed cediranib-olaparib combination therapy after progression on a PARPi. Women with HGSOC and radiographic evidence of disease progression were enrolled into one of three cohorts platinum sensitive after PARPi; platinum resistant after PARPi; or progression on standard chemotherapy after progression on PARPi (exploratory cohort). Patients received olaparib tablets 300 mg twice daily with cediranib 20 mg once daily until progression or unacceptable toxicity. The co-primary endpoints were objective response rate (RECIST v1.1) and progression-free survival (PFS) at 16 weeks. Archival tissue (PARPi-naïve) and baseline biopsy (post-PARPi) samples were mandatory. Genomic mechanisms of resistance were assessed by whole-exome and RNA sequencing.
