Metabolically healthy obesity along with chance of cerebrovascular event: any meta-analysis of potential cohort reports.
We explore how MedShr works and the range of features which promote professional compliance, protect privacy and enable case-based education. We also discuss example cases, case series and discussion themes from MedShr. In summary, the MedShr platform provides a trusted, secure environment for clinicians that uses state of the art social network technology to support case discussion whilst protecting patient privacy and confidentiality.BACKGROUND The aim of this study was to investigate the association between left ventricular diastolic dysfunction (LVDD) and erectile dysfunction (ED) without overt cardiovascular disease. METHODS A total of 80 patients with LVDD and without a history of coronary artery disease were compared with 80 age- and gender-matched healthy controls. The International Index of Erectile Function Questionnaire (IIEF-5) was used to diagnose and grade ED. LVDD and its relation with ED severity were assessed. RESULTS The mean age, body mass index, total testosterone, low- and high-density lipoprotein cholesterol, and triglyceride levels did not significantly differ between the LVDD and control groups (p > 0.05). There was a negative correlation between the stage of LVDD and IIEF-5 score (r = -0.635, p less then 0.05). Additionally, the left atrial volume index, peak TR velocity and E/e' ratio were independent risk factors for lowering the IIEF-5 score. CONCLUSIONS This study indicates that LVDD is significantly associated with ED. There were significant associations between the increased severity of ED and the presence of LVDD in middle-aged men.The aim of this review is to summarize and update current research concerning the safety of drug-coated balloons (DCBs) and drug-eluting stents (DESs) with paclitaxel (PTX) in peripheral arteries. The data from the large randomized controlled trials showed evidence of the superiority of DCBs over plain balloon angioplasty concerning efficacy. Also, the safety parameters between the two groups did not differ. However, two meta-analyses identifying an increased late mortality risk after using PTX technologies were published only a short time ago (Katsanos et al, FDA meta-analysis). In contradiction, a lot of following studies (meta- analyses, real-world analysis, retrospective review) published in 2019 and 2020, did not confirm any significant difference in all-cause death between PTX and no-PTX cohorts. The safety of PTX technologies still represents the most serious and controversial issue in peripheral interventions. Until it is definitively solved further research must continue. In daily practice, recommendations for the use of PTX products include the treatment of restenosis after PTA (not of de novo lesions), the maintenance of patency of bypasses, and angioplasty for limb salvage. In heavily calcified lesions, a prior debulking with atherectomy is suitable. Generally, the risks and benefits of the application of PTX devices should be considered in every single patient.The current seasonal inactivated influenza vaccine protects only against a narrow range of virus strains as it triggers a dominant antibody response toward the hypervariable hemagglutinin (HA) head region. The discovery of rare broadly protective antibodies against conserved regions in influenza virus proteins has propelled research on distinct antigens and delivery methods to efficiently induce broad immunity toward drifted or shifted virus strains. Here, we report that adeno-associated virus (AAV) vectors expressing influenza virus HA or chimeric HA protected mice against homologous and heterologous virus challenges. Unexpectedly, immunization even with wild-type HA induced antibodies recognizing the HA-stalk and activating FcγR-dependent responses indicating that AAV-vectored expression balances HA head- and HA stalk-specific humoral responses. Immunization with AAV-HA partially protected also ferrets against a harsh virus challenge. Results from this study provide a rationale for further clinical development of AAV vectors as influenza vaccine platform, which could benefit from their approved use in human gene therapy. © 2020 The Authors.

The aim of this study was to determine the usage rates of IHC stains in BFC, their type and indications, and their diagnostic impact. We also attempted to estimate the optimal rate of IHC use in BFC by comparing the entire laboratory's and each individual cytopathologist's IHC use rates with their respective indeterminate and malignant diagnosis rates. METHODS We conducted a retrospective study of IHC stain use in BFC during a 5.5-year interval (2013-2018) and determined the laboratory's and each individual cytopathologist's IHC usage patterns according to the final diagnosis, site, and indications for their use. RESULTS A total of 477 out of 4144 (11.5%) BFC cases had 2128 individual immunostains performed, with an average of 4.5 immunostains per case. Individual cytopathologists used IHC stains on 6.7% to 22% of their BFC cases. Pathologists with higher rates of IHC stain use than the laboratory's mean were less experienced and had higher rates of indeterminate but not of malignant diagnoses. The most common indication for the use of IHC stains was differentiating mesothelial from malignant cells. MOC31, calretinin, Ber-EP4, CD68, and D2-40 were the most commonly used of the 67 different IHC stains used in BFC. CONCLUSIONS The laboratory's mean may represent the optimal IHC use rate, as higher IHC use rates did not lead to more diagnostic certainty or higher pickup rates of malignant cells.

The mechanisms underlying this protective effect, however, are incompletely understood. The molecular events that lead to protection have been partly defined, but remain to be fully characterized. So far, however, approaches based on evolutionary dynamics have not been discussed much, but can potentially offer important insights. The aim of this review is to highlight this line of investigation and the results that have been obtained. A core observation in this respect is that aspirin has a direct negative impact on the growth dynamics of the cells, by influencing the kinetics of tumor cell division and death. We discuss the application of mathematical models to experimental data to quantify these parameter changes. We then describe further mathematical models that have been used to explore how these aspirin-mediated changes in kinetic parameters influence the probability of successful colony growth versus extinction, and how they affect the evolution of the tumor during aspirin administration.
