The majority of facilities in Japan that offer artificial insemination as part of assisted reproduction programs currently perform semen collection in the early morning. The total motile sperm count of the semen used in intrauterine insemination is an important factor in achieving successful fertilization and subsequent childbirth. The present study was initiated to determine whether semen parameters varied with the time of day at which the semen sample was collected. The study subjects were 20 fertile males and 20 infertile males with abnormal seminograms who attended our Reproduction Center. Semen was collected early in the morning (morning collection group) and in the evening (evening collection group) from the same subjects, and total motile sperm count was assessed as the primary outcome measure. As secondary outcome measures, semen volume, sperm concentration, sperm motility and total sperm count were assessed. A sexual abstinence period of 3 days was set for all participants. The semen samples were anacount; TMSC total motile sperm count.Recent evidence on resting-state functional magnetic resonance imaging (rs-fMRI) suggests that healthy human brains have a temporal organization represented in a widely complex time-delay structure. This structure seems to underlie brain communication flow, integration/propagation of brain activity, as well as information processing. Therefore, it is probably linked to the emergence of highly coordinated complex brain phenomena, such as consciousness. Nevertheless, possible changes in this structure during an altered state of consciousness remain poorly investigated. In this work, we hypothesized that due to a disruption in high-order functions and alterations of the brain communication flow, patients with disorders of consciousness (DOC) might exhibit changes in their time-delay structure of spontaneous brain activity. learn more We explored this hypothesis by comparing the time-delay projections from fMRI resting-state data acquired in resting state from 48 patients with DOC and 27 healthy controls (HC) subjects. Results suggest that time-delay structure modifies for patients with DOC conditions when compared with HC. Specifically, the average value and the directionality of latency inside the midcingulate cortex (mCC) shift with the level of consciousness. In particular, positive values of latency inside the mCC relate to preserved states of consciousness, whereas negative values change proportionally with the level of consciousness in patients with DOC. These results suggest that the mCC may play a critical role as an integrator of brain activity in HC subjects, but this role vanishes in an altered state of consciousness.OBJECTIVES To describe risk factors for acquired infection during neonatal extracorporeal membrane oxygenation and to examine the predictive value of inflammatory markers in the diagnosis of infection. METHODS A retrospective study was conducted with data for patients under 30 days supported with extracorporeal membrane oxygenation from 2003 to April 2016, in a neonatal intensive care unit. RESULTS Our study included 160 neonatal patients, the average age of connection was 8.5 days and the duration of extracorporeal membrane oxygenation support was 9.7 days. The incidence of confirmed infection was 23%. Patients with confirmed infection present more frequently vaginal delivery, lower birth weight, female sex, diagnosis of congenital diaphragmatic hernia, and longer duration of extracorporeal membrane oxygenation. When comparing the group of patients with confirmed infection and suspicion of infection, there were no significant differences in the inflammatory markers. When calculating the slope for each one, the difference in white blood cell count slope 72 h before the infection is significant; in patients with confirmed infection, the count of white blood cell increases (slope 0.25), versus the group of patients with suspected infection in whom the count decreases (slope -0.39). No differences were found in other variables. CONCLUSION Our study describes that the factors that increase the risk of infection are lower birth weight, vaginal birth, duration of extracorporeal membrane oxygenation, and a positive trend of white blood cell 72 h prior to infection/suspicion. Further studies are necessary to include or definitively rule out the use of these factors and the biomarkers as predictors of infection in neonatal patients supported with extracorporeal membrane oxygenation.BACKGROUND Glycemic variability is an important factor to consider in diabetes management. It can be assessed with multiple glycemic variability metrics and quality of control indices based on Continuous Glucose Monitoring (CGM) recordings. For this, robust, repeatable calculation is important. A widely used tool for automated assessment is the EasyGV software. The aim of this work is to implement new methods of glycemic variability assessment in EasyGV and to validate implementation of each glucose metric in EasyGV against a reference implementation of the calculations. METHODS Validation data used came from the JDRF CGM study. Validation of the implementation of metrics that are available in EasyGV software v9 was carried out and the following new methods were added and validated PGS (personal Glycemic State), IGC (Index of Glycemic Control), times in ranges, and GVP (glycemic variability percentage). Reference values considered as gold standard calculations were derived from Matlab implementation of each metric. RESULTS The Pearson correlation coefficient was above 0.98 for all metrics, except for Mean Amplitude of Glycemic Excursion (MAGE, r=0.87) as EasyGV implements a fuzzy logic approach to assessment of variability. Bland-Altman plots demonstrated validation of the new software. CONCLUSIONS The new freely available EasyGV software v10 (https//www.phc.ox.ac.uk/research/technology-outputs/easygv) is a validated, robust tool for analysing different glycemic variability and control metrics.Introduction Although checkpoint inhibitors have provided a breakthrough in how melanoma is treated, about half of patients still do not respond due to primary or acquired resistance. New strategies are, therefore, required to increase the number of patients benefiting from immunotherapy. This systematic review investigates novel combinations that may overcome immune resistance in patients with melanoma.Areas covered We provide an overview of immune-related resistance mechanisms and the various therapeutic strategies that can be considered in attempting to overcome these barriers, including combined immunotherapy approaches and combinations with chemotherapy, radiotherapy, and targeted therapy.Expert opinion The immune response is a dynamic process in which the tumor microenvironment and immune cells interact in a variety of ways. New treatment approaches aim to enrich the tumor microenvironment with immune-infiltrate and increase response to immune checkpoint inhibitors.
