This framework comprises four pillars aimed at the development of (a) an empirical definition of VILPA, (b) methods to reliably and accurately measure VILPA, (c) approaches to examine the short and long-term dose-response effects of VILPA, and (d) scalable and acceptable behavioural VILPA-promoting interventions.An amendment to this paper has been published and can be accessed via the original article.

Recurrence of Cushing disease (CD) can occur even decades after surgery. Biomarkers to predict recurrence of CD after surgery have been studied but are inconclusive.

The aim of our study was to identify specific biomarkers that can predict long-term remission after neurosurgery.

Identification of specific biomarkers to predict long-term remission of CD was performed by logistic regression analysis followed by Kaplan-Meier survival analysis, using recurrence as the dependent variable.

260 patients with CD identified from our institutional research patient data registry search tool and from patients who presented to our longitudinal multidisciplinary clinic between May 2008 and May 2018 underwent statistical analysis.

Data on clinical features, radiographs, pathology, biochemistry, treatments were collected by reviewing digital chart records.

Post-operative (post-op) cortisol as a biomarker to predict long-term remission after surgical treatment for CD.

By logistic regression analysis, post-op day one (POD1) morning (5-10 AM) serum cortisol, female sex and proliferative index had significant association with CD recurrence (OR=1.025, 95% CI1.002-1.048, p=0.032). In contrast, the post-op nadir cortisol (OR=1.081, 95% CI0.989-1.181, p=0.086), urinary free cortisol (OR=1.032, 95% CI0.994-1.07, p=0.098) and late night salivary cortisol (OR=1.383, 95% CI0.841-2.274, p=0.201) had no significant correlation with recurrence. A significant association between POD1 morning serum cortisol and long-term CD remission was verified by Kaplan-Meier analysis when using POD1 morning serum cortisol < 5 μg/dL as the cut-off.

The POD1 morning serum cortisol level has a significant association with CD recurrence.

The POD1 morning serum cortisol level has a significant association with CD recurrence.The gravitostat is purported to function as a leptin-independent, osteocyte-dependent mechanism for regulation of energy balance. If correct, reduced activation of gravitostat signaling caused by prolonged sitting may contribute to obesity. The gravitostat concept is supported by reduced body mass in rodents following surgical implantation of weighted capsules. However, the procedure induces a confounding injury response. We, therefore, sought to confirm a gravitostat by decreasing (microgravity and simulated microgravity) or increasing (simulated gravity) weight using less invasive models (spaceflight, hindlimb unloading and centrifugation). We also evaluated changes in weight following non-surgical injury (radiation). Male rats (Wistar, Sprague-Dawley and Fischer 344) ranging in age from 5-12 weeks at launch and flown for 4-19 days in low Earth orbit exhibited slightly lower (4-day flight) or no difference (all other studies) in weight compared to ground controls. Rats subjected to inflight (1.0 G) or ground (1.04 G and 1.56 G) centrifugation during a 19-day mission did not differ in weight. read more In female rats (Fischer 344), spaceflight (14 days) did not alter ovariectomy-induced weight gain. Finally, hindlimb unloading resulted in weight loss in lean and obese mice. The aforementioned findings are inconsistent with outcomes predicted by a gravitostat namely increased mass during weightlessness and decreased mass when subjected to >1 G simulated gravity. Injury (dose-associated graded increases in radiation) mimicked the leptin-independent weight changes attributed to a gravitostat. Taken together, these findings do not support gravitostat regulation of energy balance and suggest injury/stress as an alternative mechanism for weight loss induced by weighted capsules.

Little is known, or has been published previously, regarding consolidated data on the epidemiology of gynecologic cancers (GC) in Brazil. This article describes the incidence, morbidity, and mortality of women in Brazil affected with GC between the years of 2000 and 2017.

Incidence, morbidity, and mortality data from patients with a diagnosis of one out of the five most common GC, cervical (CC), uterine (UC), ovarian (OC), vulvar (VvC), and vaginal (VgC), were obtained from three governmental sources of data.

From 2000 to 2015 CC, OC, and VgC incidence rates (IRs) decreased, whereas the IRs for UC and VvC remained relatively stable. Data from 382,932 women with GC were analyzed. Most patients presented with locally advanced or advanced disease at diagnosis 60.1% of patients with CC, 31.2% of patients with UC, 67.2% of patients with OC, 45.2% of patients with VvC, and 67.0% of patients with VgC. Time from diagnosis to first treatment was ≥ 60 days in 58.0% of patients with CC, 58.5% of patients with UC, 27.0% of patients with OC, 55.3% of patients with VvC, and 52.7% of patients with VgC. Regarding mortality rates (MRs), with the exception of CC, UC, and VvC, which showed a slight decrease, MRs remained stable between 2000 and 2017.

A comparison with international data indicates that Brazilian patients are diagnosed with more advanced disease and face a longer delay between diagnosis and first treatment. Despite advances in screening and treatment, GC mortality has not decreased satisfactorily in this country.

An automated risk prediction assay has previously been shown to objectively identify patients with nondysplastic Barrett's esophagus (NDBE) who are at increased risk of malignant progression. To evaluate the predictive performance of the assay in 76 patients with NDBE of which 38 progressed to high-grade dysplasia/esophageal adenocarcinoma (progressors) and 38 did not (nonprogressors) and to determine whether assessment of additional (spatial) levels per endoscopy and/or multiple (temporal) time points improves assay performance.

In a blinded, nested case-control cohort, progressors and nonprogressors were matched (age, sex, and Barrett's esophagus length). All random biopsy levels from the baseline endoscopy (spatial samples) and all available previous endoscopies back to 10 years before progression (temporal samples) were assayed. Because the 11 ratio of progressors to nonprogressors does not reflect the real-world Barrett's population, negative and positive predictive values were adjusted for prevalence.
