Meta Analysis Comparative Study
Thoracic endovascular aortic repair versus open chest surgical repair for patients with type B aortic dissection: a systematic review and meta-analysis.
Aim: This meta-analysis study aimed to compare the efficacy and safety of TEVAR versus OCSR for TBAD patients. Methods: We systematically searched PubMed, EmBase, and the Cochrane library to identify studies compared the effectiveness of TEVAR and OCSR in TBAD patients from the inception up to July 2019. The summary results were calculated using a random-effects model. ⋯ Moreover, the reduced risk of acute renal failure, respiratory failure and bleeding was detected in TEVAR group. The treatment effects of TEVAR versus OCSR on specific complications should be further verified by a study with high-level of evidence. Key messageComprehensive collected studies investigated the treatment effectiveness between TEVAR and OCSR for TBAD patientsTEVAR resulted in more survival benefits, in addition to lower risk of acute renal failure, respiratory failure and bleedingThe results of stratified analyses according to patients' characteristics were conducted.

Albumin is the most abundant plasma protein and albumin infusion is commonly used. Conventionally, the biologic and therapeutic effects of albumin have been thought to be due to its oncotic properties. However, albumin has a variety of biologic functions, including molecular transport, anti-oxidation, anti-inflammation, endothelial stabilisation, anti-thrombotic effects, and the adjustment of capillary permeability. ⋯ Impaired albumin function has been reported in a variety of liver diseases, and is associated with disease severity and prognosis, thereby proposing the concept of 'effective albumin concentration'. Albumin dysfunction occurs earlier than other conventional indicators, and albumin dysfunction may be a new biomarker of early impairment in liver function. Many exogenous and endogenous factors lead to post-translational modifications of albumin, which alters the three-dimensional structure of albumin, resulting in a decrease in its biological activity.

Epidemiologically, high-density lipoprotein (HDL) cholesterol levels have been inversely associated to cardiovascular (CV) events, although a Mendelian Randomisation Study had failed to establish a clear causal role. Numerous atheroprotective mechanisms have been attributed to HDL, the main being the ability to promote cholesterol efflux from arterial walls; anti-inflammatory effects related to HDL ligands such as S1P (sphingosine-1-phosphate), resolvins and others have been recently identified. Experimental studies and early clinical investigations have indicated the potential of HDL to slow progression or induce regression of atherosclerosis. ⋯ Key messagesHigh-density lipoproteins have as a major activity that of removing excess cholesterol from tissues (particularly arteries). Knowledge on the activity of high-density lipoproteins on health have however significantly widened. HDL-therapy may help to improve stent biocompatibility and to reduce peripheral arterial resistance in heart failure.

Objective: To determine if presence of co-existing medically unexplained syndromes or psychiatric diagnoses affect symptom frequency, severity or activity impairment in Chronic Fatigue Syndrome. Patients: Sequential Chronic Fatigue Syndrome patients presenting in one clinical practice. Design: Participants underwent a psychiatric diagnostic interview and were evaluated for fibromyalgia, irritable bowel syndrome and/or multiple chemical sensitivity. ⋯ This paper shows that the presence of co-existing psychiatric diagnoses does not impact on any aspect of the phenomenology of medically unexplained fatigue also known as chronic fatigue syndrome. Therefore, psychiatric status is not an important causal contributor to CFS. In contrast, the presence of other medically unexplained syndromes (irritable bowel syndrome; fibromyalgia and/or multiple chemical sensitivity) do impact on the illness such that the more of these that co-exist the more health-related burdens the patient has.

Review
Insulin resistance takes center stage: a new paradigm in the progression of bipolar disorder.
Bipolar Disorder (BD) is a major psychiatric illness affecting up to 5% of the population. BD can progress over time to a chronic "neuroprogressive" course with cognitive and functional impairment. Currently, there are no validated predictors indicating which patients will develop a neuroprogressive course and there are no specific treatments. ⋯ Insulin resistance is present in more than half of all bipolar patients and is associated with a chronic course of illness, lack of response to mood stabilizing treatment, cognitive impairment and poor functional outcomes. Insulin resistance may modify the course of bipolar disorder and promote neuroprogression. Insulin resistance may be a testable and potentially modifiable risk factor for neuroprogression in bipolar disorder.
