In Italy elective bariatric and metabolic surgery was cancelled on February 21,2020 at the beginning of the so-called phase 1 of the SARS-CoV-2 outbreak. Gradually it was restarted on May 4,2020 at the beginning of the so-called phase 2, when epidemiological data showed containment of the infection. Before the outbreak in eight high-volume bariatric centers 840 patients were surgically treated developing a Covid-19 infection, during phase 1, in only 5 cases (0.6%) without mortality. The post-operative complication rate was similar when compared to the 836 subjects submitted to bariatric surgery the year before. Since the high prevalence of infection in subjects with BMI > 30, it was argued that early intervention on obesity during phase 2 could help to minimize the effects of the disease in the event of a possible reversion to a SARS-CoV-2 outbreak phase 1. At the same time a prospective observational study from July 1 till the WHO declaration of the end of the pandemic has started in the eight high volume centers to monitor the post-operative outcome and its effect on SARS-CoV-2 infection.
To assess outcomes following post-hemorrhagic ventricular dilatation (PHVD) among infants born at ≤26weeks of gestation.

Observational study of infants born April 1, 2011, to December 31, 2015, in the Eunice Kennedy Shriver National Institute of Child Health and Human Development Neonatal Research Network and categorized into 3 groups PHVD, intracranial hemorrhage without ventricular dilatation, or normal head ultrasound. PHVD was treated per center practice. Neurodevelopmental impairment at 18-26months was defined by cerebral palsy, Bayley Scales of Infant and Toddler Development, 3rd edition, cognitive or motor score <70, blindness, or deafness. Multivariable logistic regression examined the association of death or impairment, adjusting for neonatal course, center, maternal education, and parenchymal hemorrhage.

Of 4216 infants, 815 had PHVD, 769 had hemorrhage without ventricular dilatation, and 2632 had normal head ultrasounds. Progressive dilatation occurred among 119 of 815 infants; the initialreased among those with progressive ventricular dilation requiring intervention.Pancreatic cancer is a lethal disease with limited treatment options for cure. A high degree of intrinsic and acquired therapeutic resistance may result from cellular alterations in genes and proteins involved in drug transportation and metabolism, or from the influences of cancer microenvironment. Mechanistic basis for therapeutic resistance remains unclear and should profoundly impact our ability to understand pancreatic cancer pathogenesis and its effective clinical management. Recent evidences have indicated the importance of epigenetic changes in pancreatic cancer, including posttranslational modifications of proteins. We will review new knowledge on protein arginine methylation and its consequential contribution to therapeutic resistance of pancreatic cancer, underlying molecular mechanism, and clinical application of potential strategies of its reversal.
Insulin resistance in visceral adipose tissue (VAT), skeletal muscle and liver is a prominent feature of most patients with obesity. How this association arises remains poorly understood. selleck chemicals The objective of this study was to demonstrate that the decrease in insulin receptor (INSR) expression and insulin signaling in VAT from obese individuals is an early molecular manifestation that might play a crucial role in the cascade of events leading to systemic insulin resistance.

To clarify the role of INSR and insulin signaling in adipose tissue dysfunction in obesity, we first measured INSR expression in VAT samples from normal-weight subjects and patients with different degrees of obesity. We complemented these studies with experiments on high-fat diet (HFD)-induced obese mice, and in human and murine adipocyte cultures, in both normoxic and hypoxic conditions.

An inverse correlation was observed between increasing body mass index and decreasing INSR expression in VAT of obese humans. Our results indicate that VAT-specific downregulation of INSR is an early event in obesity-related adipose cell dysfunction, which increases systemic insulin resistance in both obese humans and mice. We also provide evidence that obesity-related hypoxia in VAT plays a determinant role in this scenario by decreasing INSR mRNA stability. This decreased stability is through the activation of a miRNA (miR-128) that downregulates INSR expression in adipocytes.

We present a novel pathogenic mechanism of reduced INSR expression and insulin signaling in adipocytes. Our data provide a new explanation linking obesity with systemic insulin resistance.

Heart transplantation is the mainstay of treatment for patients in end-stage heart failure. This study sought to contrast survival after transplantation with that of the general population to quantify standardized mortality rates using a nested case-control study design.

Control subjects were noninstitutionalized inhabitants of the United States identified through the National Longitudinal Mortality study. Case subjects were adults who underwent heart transplantation between 1990 and 2007 and identified through the Organ Procurement and Transplantation Network. Propensity-matching (51, nearest neighbor, caliper= 0.1) was utilized to identify suitable control subjects based on age, sex, race, and state of permanent residency. The primary study endpoint was 10-year survival.

In all, 31,883 heart transplant recipients were matched to 159,415 noninstitutionalized residents of the United States. The 10-year survival of heart transplant recipients was 53%. The population expected mortality rate was 15.9 deathtly declined over time and will likely continue to decrease.
Outcomes after segmentectomy compare favorably with those after lobectomy in patients with stage I non-small cell lung cancer (NSCLC). Whether long-term outcomes vary by segmentectomy location is unclear. We investigated whether disease-free survival (DFS) and overall survival (OS) differ by segmentectomy location after intentional segmentectomy for clinical T1 N0 M0 NSCLC.

Patients who received intentional segmentectomy for cT1 N0 M0 NSCLC from 2000 to 2018 were reviewed. Patients with prior lung cancer, forced expiratory volume in 1 second of less than 50%, or R1/R2 resection were excluded. Segmentectomy groups were left (L) basilar, L segment 6, L lingula, L trisegment; right (R) basilar (R_Bas), segment 6 (R_S6), and R upper. The 5- and 10-year DFS and OS were estimated using Kaplan-Meier and compared between groups using the log-rank test. Factors associated with DFS and OS were determined using Cox proportional hazards models.

In total, 416 patients met the inclusion criteria. Segmentectomy groups differed with regard to surgical approach, mediastinal lymphadenectomy, lymphovascular invasion, tumor histology, margin distance, and adjuvant therapy.
