Background: Superior vena cava (SVC) syndrome is caused by the obstruction of the SVC and can result in significant morbidity and mortality. In contemporary practice, endovascular therapy (ET) has become the standard of care for a majority of these patients. This study is a systematic review and meta-analysis of the available literature to assess technical success, restenosis, and recurrence of SVC syndrome following endovascular intervention. Methods: For this meta-analysis, we conducted a systematic literature review of PubMed, Cochrane Library, and Embase databases from inception to April 14, 2021 for studies on ET for SVC syndrome. Studies included full-length journal articles on the use of ET among adults with SVC syndrome. Case reports or case series with fewer than 20 patients were excluded. We evaluated the endpoints of technical success rate, restenosis rate, and recurrence rates in SVC syndrome patients after endovascular stenting. The results of this study were calculated using random-effects models. Findings: We identified 6,012 reports, of which 39 studies met our inclusion criteria and were included for analysis. A total of 2200 patients received ET for SVC syndrome. The weighted technical success rate was 98.8% (95% CI 98.2À99.3) with low heterogeneity (I 2 =17.4%, p = 0.185), restenosis rate was 10.5% (95% CI 8.4À12.6) with moderate heterogeneity (I 2 =53.5%, p<0.001), and recurrence rate was 10.8% (95% CI 8.1À13.5) with high heterogeneity (I 2 =75.8%, p<0.001). Total complication rate was 8.6% (95% CI 7.3%-9.9%) with a mean complication rate of 7.5% (95% CI 4.7%-10.3%). Interpretation: Our systematic review revealed high technical success, low restenosis, and low recurrence rates following ET. Collectively, these results support the paradigm of ET as an effective and safe treatment for patients with SVC syndrome.

Running Title: Boston DeclarationWord Count: 689 (not including the table) 2 Nearly three out of every four deaths globally in 2017 were caused by non-communicable diseases (NCDs). 1 Many countries have made progress reducing NCD risk factors such as tobacco use, hyperlipidemia, and hypertension, but no countries have successfully reversed the increasing trends in diabetes prevalence and mortality from diabetes is increasing. 1 This represents a massive global health failure considering the fact that type 2 diabetes is largely preventable with lifestyle modification and that cost-effective treatments exist for both type 2 and type 1 diabetes. 2 Specific concern is needed for type 1 diabetes, which without insulin, it is fatal.In parallel, forced migration has reached a record high with 68.5 million people displaced from their homes around the world, 85% being hosted in low or middle-income countries such as, Uganda, Lebanon, and Pakistan, and 65% occurring in protracted refugee situations. 3 In addition, there are over 100 million conflict-affected non-displaced people and 175 million people who are affected by natural disasters annually. 4 These individuals are particularly vulnerable in crises due to disrupted health services and unpredictable-and often unhealthy-food supplies, which may exacerbate their condition and lead to complications.To date, diabetes and other NCDs have largely been underserved in humanitarian settings. 5,6,7 The true scope of the problem has not been established and it is not known which interventions are efficacious, feasible, and cost-effective in these contexts. With respect to type 1 diabetes, arguably the most immediately life-threatening NCD, the supply and cost of insulin, blood glucose monitoring and diagnostic tools are barriers for both humanitarian responders and their host countries, as well as patient adherence, life expectancy, quality of life, follow-up and provider training in diabetes care.In order to begin to address these major gaps, on 4-5 April 2019, Harvard University convened a meeting of humanitarian and other actors in global health to discuss the immediate needs and barriers to tackling diabetes in humanitarian crises, and to adopt a unified, action-oriented agenda to address this pressing global health issue (http://globalendocrinology.bwh.harvard.edu/symposium). Whilst it was recognised that there are substantial gaps in care for diabetes in all low-resource settings, 8 not just humanitarian crises, and that many other NCDs (e.g., cardiovascular disease, chronic obstructive pulmonary disease and asthma) are also prevalent globally and inadequately addressed in humanitarian settings, 9 we chose to prioritize efforts on diabetes in humanitarian crises, for the following reasons:First, because people with type 1 diabetes who cannot access insulin and continuity of care in a crisis are at acute risk of death. The principles of the Humanitarian Charter and United Nations Universal Declaration of Human Rights include the right to life with dignity. 10 The human rig...

This nationwide observational study suggests that one-third of all patients undergoing CDT receive IVCFs. IVCF use was not associated with a decrease in in-hospital mortality but was associated with higher inpatient charges and longer length of stay.

INTRODUCTION: The outcomes of transjugular intrahepatic portosystemic shunt (TIPS) placement in patients with hepatic encephalopathy (HE) are controversial. We studied the relationship of pre-TIPS HE in patients undergoing TIPS for refractory ascites on all-cause mortality and development of post-TIPS HE. METHODS: A single-center retrospective comparison study was performed for patients undergoing TIPS for refractory ascites. Survival by history of pre-TIPS HE was demonstrated with Kaplan-Meier curves. Univariate and multivariate logistic regression analyses were performed to identify the predictors of post-TIPS clinical outcomes for patients with and without pre-TIPS HE. RESULTS: We identified 202 TIPS recipients (61% male, mean ± SD; age 59.1 ± 10.2 years; mean model for end-stage liver disease score 17.3 ± 6.9). Pre-TIPS HE did not predispose patients for increased all-cause mortality, increased risk of experiencing HE within 60 days, or increased risk of hospital admission for HE within 6 months. A multivariate analysis demonstrated that total bilirubin (odds ratio [OR] 1.03; P = 0.016) and blood urea nitrogen (OR 1.15; P = 0.002) were predictors for all-cause mortality within 6 months post-TIPS. Age ≥65 years (OR 3.92; P = 0.004), creatinine (OR 2.22; P = 0.014), and Child-Pugh score (OR 1.53; P = 0.006) were predictors for HE within 60 days post-TIPS. Predictors of intensive care admission for HE within 6 months post-TIPS included age ≥65 years (OR 8.84; P = 0.018), history of any admission for HE within 6 months pre-TIPS (OR 8.42; P = 0.017), and creatinine (OR 2.22; P = 0.015). DISCUSSION: If controlled, pre-TIPS HE does not adversely impact patient survival or clinical outcomes, such as development of HE within 60 days of TIPS or hospital admission for HE within 6 months. Patients may be able to undergo TIPS for refractory ascites despite a history of HE.

The prevalence of food allergies continues to rise, and with limited existing therapeutic options there is a growing need for new and innovative treatments. Food allergies are, in a large part, related to environmental influences on immune tolerance in early life, and represent a significant therapeutic challenge. An expanding body of evidence on molecular mechanisms in murine models and microbiome associations in humans have highlighted the critical role of gut dysbiosis in the pathogenesis of food allergies. As such, the gut microbiome is a rational target for novel strategies aimed at preventing and treating food allergies, and new methods of modifying the gastrointestinal microbiome to combat immune dysregulation represent promising avenues for translation to future clinical practice. In this review, we discuss the intersection between the gut microbiome and the development of food allergies, with particular focus on microbiome therapeutic strategies. These emerging microbiome approaches to food allergies are subject to continued investigation and include dietary interventions, pre- and probiotics, microbiota metabolism-based interventions, and targeted live biotherapeutics. This exciting frontier may reveal disease-modifying food allergy treatments, and deserves careful study through ongoing clinical trials.
