The relationship between functional mitral stenosis (MS) after mitral valve (MV) repair and long-term clinical outcomes is not fully understood. Therefore, we reviewed an institutional series to identify the determinants of functional MS and its effect on long-term clinical outcomes after MV repair for degenerative mitral regurgitation.

Between January 1990 and December 2015, 792 patients who underwent MV repair for degenerative mitral regurgitation were retrospectively enrolled and divided into 2 groups functional MS (n= 192) (≥5 mm Hg mean diastolic pressure gradient across the MV) and nonfunctional MS (n= 600) (<5 mm Hg mean diastolic pressure gradient). Mean follow-up was 11.6 ± 5.8 years.

After propensity-score matching, patients' characteristics were comparable between groups (n=192/group). At 20 years, the functional MS group had significantly lower rates of freedom from new-onset atrial fibrillation (73.0% ± 5.6% versus 93.2% ± 2.3%; P= .003), overall survival (72.1% ± 4.6% versus 85.6%±4.3%; exacerbation. As a result, functional MS increased the risk for new-onset atrial fibrillation, MV reoperation, and decreased long-term survival.
Endoscopic submucosal dissection (ESD) is one of the curative treatment options for superficial esophageal cancer with minimal risk of lymph node metastasis. Prior to ESD, accurate clinical staging is important to select the appropriate candidate. We aimed to estimate the practicality of endoscopic ultrasound (EUS) to select pTis and pT1a.

We included patients with squamous esophageal cancers who underwent surgical resection or ESD between 2005 and 2018. Pathologic reports were reviewed retrospectively, and pathologic T staging was compared to clinical stage evaluated by EUS.

Among 532 cases, 321 cases were superficial esophageal cancer (pTis, 42; pT1a, 115; pT1b, 164). Accuracy rates, sensitivity, specificity, positive predicted value, and negative predicted value for selecting cT1a by EUS were 82.3%, 60.5%, 91.5%, 74.8%, and 84.7% respectively. The rate of overstaged pTis-T1a was 39.5%. In multivariable analysis, tumor size (>2 cm), poor differentiation, protruding gross type, and use of conventional EUS (vs. miniprobe) were associated factors for overstaging of pTis-T1a.

Prediction accuracy of EUS for selecting the mucosal esophageal cancer that can be treated with ESD was favorable. Target lesions with large size (>2 cm), poor differentiation, protruding morphology were related to T overstaging, and precaution should be taken in evaluating clinical stage for cancers with those conditions. Furthermore, miniprobe EUS provides higher accuracy for squamous esophageal cancers confined to mucosa.

Transforming growth factor β (TGF-β) has appeared as a neuroprotective protein in various indignities. However, the TGF-β mechanism of protective effects against oxidative stress damage in RGCs still undetermined. In our research, we investigated the regulatory mechanisms and potential effects of TGF-β1 & TGF-β2 in hydrogen peroxide (H2O2)-stimulated oxidative stress of RGCs in vitro. By a series of cell functional qualitative analysis, such as MTT cell viability assay, wound healing ability assay, apoptosis assay, intracellular ROS detection, immunoblot analysis, intracellular GSH content, and high-resolution respirometry, we illustrated the cell state in oxidative stress-induced injury. Results of protein expression showed that TGF-β1 & TGF-β2 was upregulated in RGCs after H2O2 stimulation. Cell functional assays resulted that knockdown of TGF-β1 & TGF-β2 reduced survival rate whereas enhanced apoptosis and accumulation of reactive oxygen species (ROS). Especially TGF-β1 upregulation promoted the protein expression of aldehyde dehydrogenase 3A1 (ALDH3A1) and increased the activity of antioxidant and neuroprotection pathways. find more Additionally, TGF-β1 & TGF-β2 on antioxidant signaling was related to activation of heme oxygenase-1 (HO-1) and nuclear factor erythroid 2-related factor (Nrf2), which are stress-response proteins. ROS accumulation followed by the accumulation of hypoxia-inducible factor (HIF-1α) caused mitochondrial damage and led to neurodegeneration. In summary, our results demonstrated that TGF-β1 preserves RGCs from free radicals-mediated injury by upregulating the activation of Nrf2 expression and HO-1 signaling balance HIF-1α upregulation, implying a prospective role of TGF-β1 in retinal neuroprotection-related therapies.Mitochondria play an essential role in cellular metabolism, generation of reactive oxygen species (ROS), and the initiation of apoptosis. These properties enable mitochondria to be crucial integrators in the pathways of tumorigenesis. An open question is to what extent variation in the mitochondrial genome (mtDNA) contributes to the biological heterogeneity observed in human tumors. In this review, we summarize our current understanding of the role of mtDNA genetics in relation to human cancers.
The aim of this review was to summarize the most common extrapulmonary manifestations in pediatric patients with COVID-19, as well as to discuss clinical, epidemiological, and pathophysiological aspects of these clinical presentations in children.

An extensive search of literature was performed in order to identify pediatric cases with extrapulmonary manifestations between January 1, 2020 and June 21, 2020. Generic keywords, such as "Novel coronavirus" or "Novel coronavirus 2019" or "2019 nCoV" or "COVID-19" or "SARS-CoV-2" were searched on PubMed database, associated either with age filters or generic pediatric terms.

A total of 28 articles, including 199 patients, were considered suitable to review and data extraction. The main findings were summarized in tables. The main non-pulmonary manifestations in pediatric patients, in decreasing order of frequency, were gastrointestinal, renal, cardiovascular, neurological, hematological and lymphatic, cutaneous, hepatic, ocular, olfactory, and gustatory. Multisystem impairment and Kawasaki-like disease were also described.
