Leaflet resection and chordal reconstruction are established repair techniques for posterior mitral valve (MV) prolapse. check details This study aimed to compare the clinical results of the resect and respect approaches, with a particular focus on MV hemodynamics.

Overall, 291 patients who underwent elective MV repair for isolated posterior leaflet prolapse between 2012 and 2020 were enrolled. Patients who underwent leaflet resection alone were classified as the "resection" group (n = 166), while patients who underwent neochordal replacement with/without limited leaflet resection were classified as the "respect" group (n = 125). Early postoperative MV hemodynamics and midterm repair durability were compared between the groups.

The annuloplasty ring size was significantly larger in the respectgroup than in the resection group (31.0 ± 2.1vs. 30.4 ± 2.0 mm, p = .028). The respectgroup showed significantly lower mean MV gradient (2.6 ± 1.1vs. 3.0 ± 1.4 mmHg, p = .03) and larger effective orifice area (EOA) (1.86 ± 0.48vs. 1.66 ± 0.47 cm

, p < .001) than the resection group. Multivariable analysis identified the respect approach, younger age, female sex, larger ring size, and partial band as independent determinants of larger EOA. The rate of freedom from moderate or greater recurrent mitral regurgitation 5 years postoperatively was 90.9% in both groups.

The respect approach allowed for a lower MV gradient and a larger EOA than the resection approach, which is possibly due to the capability of implanting a larger annuloplasty ring.

This study aimed to identify a set of biomarkers through a GWAS for growth curve parameters in crossbred chickens using the Illumnia 60K chicken SNP Beadchip. Growth data were collected from a total of 301 birds from cross of a broiler line and native chickens. Using the Gompertz-Laird model, two growth curve parameters, the instantaneous growth rate per day (L) and the coefficient of relative growth or maturing index (k), were estimated. The L and k were used to estimate five derived parameters, namely asymptotic (mature) body weight, body weight at inflection point, age at the inflection point, average growth rate and maximum growth rate. These parameters were considered as phenotypic values in the GWAS based on generalized linear models. The results of the GWAS indicated 21 significant markers, which were located near or within 46 genes. A number of these genes, such as GH, RET, GRB14, FTSJ3 and CCK, are important for growth and meat quality in chickens, and some of them are growth related in other species such as sheep and cattle (GPI, XIRP2, GALNTL6, BMS1, THSD4, TRHDE, SHISA9, ACSL6 and DYNC1LI2). The other genes are associated with developmental biological pathways. These genes are particuarly related to body weight, average daily gain and growth QTL. The results of this study can shed light on the genetic mechanism of biological functions of growth factors in broiler chickens, which is useful for developing management practices and accelerating genetic progress in breeding programs.

Limited data exist on the utility of ultrasonographic evaluation of inferior vena cava (IVC) in acute respiratory distress syndrome (ARDS). We studied the value of IVC diameter in assessing cardio-circulatory performance in ARDS using strain echocardiography.

Retrospective cross-sectional analysis of Doppler echocardiograms of patients with moderate-severe ARDS was performed. Right ventricle (RV) parameters, IVC diameter, and left ventricle (LV) systolic and diastolic parameters were collected. RV free wall strain (RVFWS) and LV global longitudinal strain (LVGLS) were calculated.

Fifty-one patients were dichotomized into two groups with IVC>2.1cm (dilated) and with IVC≤2.1cm (nondilated). The dilated IVC group presented worse hypoxemic profile, hypotension, and poor perfusion markers. No significant associations with positive end-expiratory pressure or lung mechanics were observed. Dilated IVC was associated with impaired RV function, high central venous pressure, elevated pulmonary artery pressure, and LV systolic and diastolic dysfunctions. Strongest predictors of a dilated IVC were RVFWS, LVGLS, and tissue Doppler mitral annular early diastolic velocity. Dilated IVC predicted a global cardiac dysfunction defined by strain echocardiography (GCDS) with high sensitivity and specificity.

In ARDS, strain echocardiography analyses demonstrated that a dilated IVC is associated with GCDS and impaired hemodynamics independent of lung mechanics. A dilated IVC should be considered a marker of circulatory distress, signaling the potential necessity for improved hemodynamic optimization.

But, while for the aortic valve the competition, even for nonhigh risk patients, has become tightened, in the context of mitral regurgitation, the surgery seems to not have competitors. In fact looking the results of studies published so far, a question arises Is surgery the fair competitor for the Mitraclip? The meta-analysis by Abdul Khader et al. summarized few evidences present in this field, only 11 observational studies and 1 randomized trial, providing an awesome response "NO." Is therefore not a case if recently two trials, MITRA-FR and COAPT, chose to use as competitor for MitraClip, more rightly, medical therapy instead of surgery. In conclusions, in case of mitral regurgitation (MR), surgery is still largely the gold standard treatment and so MitraClip cannot be mention at all as competitor of surgery. It can be the right choice of case of primary MR where patients showed high risk for surgery. In case of secondary MR, especially with large and poor left ventricle we should wait for a clear answer on its role, yet.

Autoimmune bullous diseases (AIBD) are rare disorders characterized by autoantibody formation against components of adhesion molecules; in pemphigoid diseases (PD), these are proteins of hemidesmosomes and basement membrane, important for cell-matrix adhesion in skin and/or mucous membranes. Incidences of these diseases vary considerably between different populations.

To establish a registry prospectively recruiting all AIBD patients in a geographically well-defined region in Northern Germany (Schleswig-Holstein).

Only patients with verified disease (by clinical presentation, histology, direct and/or indirect immunofluorescence and /or ELISA) living in Schleswig-Holstein were included. Incidences of PD were estimated based on the total number of inhabitants in Schleswig-Holstein, stratified by birth year and sex.

Of 67 patients with PD [35 male, 32 female, mean age 75 (standard deviation 14.3years)], 83% were patients with bullous pemphigoid [n=56, 28 male, 28 female, mean age 78 (SD 9.9)]. The resultidence among PD patients was found for bullous pemphigoid. The incidence of bullous pemphigoid is considerably increased compared to previous reports and reveals regional differences. Further studies are needed in order to clarify these findings.

Workers' compensation claims among Medicare beneficiaries have not been described previously. To examine the healthcare burden of work-related injury and illness among Medicare beneficiaries, we assessed the characteristics, healthcare utilization, and financial costs among Medicare beneficiaries with claims for which workers' compensation was the primary payer.

We extracted final action fee-for-service Medicare claims from 1999 to 2016 where workers' compensation had primary responsibility for claim payment and beneficiary, claim type, diagnoses, and cost information from these claims.

During 1999-2016, workers' compensation was the primary payer for 2,010,200 claims among 330,491 Medicare beneficiaries, and 58.7% of these beneficiaries had more than one claim. Carrier claims submitted by noninstitutional providers constituted the majority (94.5%) of claims. Diagnosis codes indicated 19.4% of claims were related to diseases of the musculoskeletal system and connective tissue and 12.9% were related to dg Medicare beneficiaries resulting from employment and identifies a need for more comprehensive collection and surveillance of work-related medical claims.Study of vocal fold (VF) mucosal biology requires essential human vocal fold epithelial cell (hVFE) lines for use in appropriate model systems. We steadily transfected a retroviral construct containing human telomerase reverse transcriptase (hTERT) into primary normal hVFE to establish a continuously replicating hVFE cell line. Immortalized hVFE across passages have cobblestone morphology, express epithelial markers cytokeratin 4, 13 and 14, induced hTERT gene and protein expression, have similar RNAseq profiling, and can continuously grow for more than 8 months. DNA fingerprinting and karyotype analysis demonstrated that immortalized hVFE were consistent with the presence of a single cell line. Validation of the hVFE, in a three-dimensional in vitro VF mucosal construct revealed a multilayered epithelial structure with VF epithelial cell markers. Wound scratch assay revealed higher migration capability of the immortalized hVFE on the surface of collagen-fibronectin and collagen gel containing human vocal fold fibroblasts (hVFF). Collectively, our report demonstrates the first immortalized hVFE from true VFs providing a novel and invaluable tool for the study of epithelial cell-fibroblast interactions that dictate disease and health of this specialized tissue.

To evaluate if prostatic ductal adenocarcinoma (PDA) independently predicts poorer pathological and oncological outcomes after radical prostatectomy (RP).

Utilizing a large prospective uro-oncology registry, clinicopathological parameters of 1027 consecutive patients who underwent RP (2008-2017) were recorded. Oncological outcomes were determined by failure to achieve unrecordable PSA postoperatively and biochemical failure (BCF).

PDA was present in 79 (7.7%) patients, whereas 948 (92.3%) patients had conventional prostatic acinar adenocarcinoma (PAA). Patients with PDA were older (mean 64.4 vs. 62.8-years old; p = .045), had higher PSA at diagnosis (mean 12.53 vs. 10.80 ng/ml; p = .034), and a higher percentage of positive biopsy cores (mean 39.34 vs. 30.53%; p = .006). Compared to PAA, PDA exhibited a more aggressive tumor biology (1) Grade groups 4 or 5 (26.6 vs. 9.4%, p < .001), (2) tumor multifocality (89.9 vs. 83.6%; p = .049), and (3) tumor size (mean 2.97 vs. 2.00 cm; p < .001). On multivariate analysis, PDA was independently associated with locally advanced disease (p = .
