At 20.0% of the predicted CRE acquisition risk in the training set, the calibration-in-the-large was 0, slope of the calibration plot was 1, c-statistic was .93, sensitivity was 85.5%, and specificity was 84.8%. The performance was relatively good in the subsets and new test set.
The nomogram can be used to monitor the CRE acquisition risk for ICU patients who have a similar case mix to patients in the study hospitals. Future studies need to involve more rigorous methodology and larger samples.

Whether damage control orthopedics (DCO) or early total care (ETC) is the best way to treat polytrauma patients who have suffered a bilateral femoral shaft fracture remains unanswered. The aim of this study was to evaluate the morbidity of bilateral femur fractures treated by simultaneous intramedullary (IM) nailing according to ETC principles.
This retrospective single-centre study included all polytrauma patients who had suffered a femoral shaft fracture and were treated at our level I trauma centre. Demographic data, associated lesions, injury severity score (ISS) and occurrence of acute respiratory distress syndrome (ARDS) were collected prospectively in our trauma database. Unilateral fractures (UF) were compared to bilateral fractures (BF). The risk of ARDS was evaluated by multivariate logistic regression.
Between 2010 and 2019, 176 UF (88%) and 25 BF (12%) were included. Patients with BF had a higher ISS (36 vs. 25, p<0.001) and more brain injuries (44% vs. 15%, p=0.001) than patients with a UF. More blood transfusions were done in BF than UF (4.0 vs. 1.6 units, p=0.002). The incidence of ARDS was higher in BF patients than UF (36% vs. 4%) with longer stay in intensive care (18 vs. https://www.selleckchem.com/products/blu-667.html 12 days, p=0.02) and in the hospital (32 vs. 23 days, p=0.006). There were no deaths in either group. The risk of ARDS was correlated to ISS, but not to bilaterality.
Studies on DCO and ETC report similar mortality and ARDS rates for BF. ISS appears to determine the postoperative morbidity irrespective of how the patients are managed. In contrast with DCO, perioperative intensive care has a predominant role in ETC, allowing early definitive fixation of fractures, even in severely injured patients.
Bilateral femoral shaft fractures are a sign of severe trauma leading to high postoperative morbidity. The patient is likely to have concomitant severe injuries. Simultaneous ECM can be done emergently providing appropriate perioperative intensive care management.

Although one of the optimal treatment methods for fixing intertrochanteric femur fractures (ITFF) is the proximal femoral nail (PFN) that still has some complications, during implantation of PFN, there might be a V-effect on the trochanteric fracture line, which leads to hinging from the inferior of the femoral neck of the fracture and consequently, fixation of the hip in a varus position. The aim of this study was to identify the causes of the V-effect, and possible preventative solutions.
The V-effect is seen at a considerable rate and is an important iatrogenic complication with a high re-operation rate.
A retrospective review of ITFFs treated with PFN was conducted. link2 Fractures were classified from the injury films using the Arbeitsgemeinschaft für Osteosynthesefragen/Orthopedic Trauma Association (AO/OTA) classification, and quality of reduction, rate of complication and re-operation, and the V-effect was evaluated on the initial postoperative films.
A total of 667 patients met the inclusion criteria. The overall rate of complications was 19.8% and re-operation was 5.1%. According to the AO/OTA fracture classification, 393 (58.9%) fractures were stable, and 274 (41.1%) were unstable. The reduction was good in 538 patients (80.7%), acceptable in 14 (2.1%) and poor in 115 (17.2%) patients. The V-effect was detected in 9.4% (n=63) of all patients, and re-operation was required in 19.1% (n=12) of these.
The V-effect is an iatrogenic complication during fixation of ITFF with PFN. To avoid complications of the V-effect, either constant anatomic reduction should be provided during and before implantation of PFN, or a more suitable instrument should be selected.

Over the last decades, several progresses have been made in understanding the function and regulation of the prototypical inflammatory cytokine (IL-1) in human diseases. IL-1α and IL-1β deregulated signaling causes devastating diseases manifested by severe acute or chronic inflammation. In this review, we examine and compare the key aspects of IL-1α and IL-1β biology and regulation and discuss their importance in the initiation and maintenance of inflammation that underlie the pathology of many human diseases. We also report the current and ongoing inhibitors of IL-1 signaling, targeting IL-1α, IL-1β, their receptor or other molecular compounds as effective strategies to prevent or treat the onset and progression of various inflammatory disorders.Melanocortin-4 receptor (MC4R), the most important monogenetic cause of human metabolic disorders, has been of great interest to many researchers in the field of energy homeostasis and public health. Because MC4R is a vital pharmaceutical target for maintaining controllable appetite and body weight for professional athletes, previous studies have mainly focused on the central, rather than the peripheral, roles of MC4R. Thus, the local expression of MC4R and its behavioral regulation remain unclear. In an attempt to shed light on different directions for future studies of MC4R signaling, we review in this article a series of recent and important studies exploring the peripheral functions of MC4R and the direct physiological interaction between peripheral organs and central MC4R neurons.The characterization of the distinct dynamic functional connectivity (dFC) patterns that activate in the brain during rest can help to understand the underlying time-varying network organization. The presence and behavior of these patterns (known as meta-states) have been widely studied by means of functional magnetic resonance imaging (fMRI). However, modalities with high-temporal resolution, such as electroencephalography (EEG), enable the characterization of fast temporally evolving meta-state sequences. Mild cognitive impairment (MCI) and dementia due to Alzheimer's disease (AD) have been shown to disrupt spatially localized activation and dFC between different brain regions, but not much is known about how they affect meta-state network topologies and their network dynamics. The main hypothesis of the study was that MCI and dementia due to AD alter normal meta-state sequences by inducing a loss of structure in their patterns and a reduction of their dynamics. Moreover, we expected that patients with MCI degradation of dynamic brain flexibility.Resting state brain activity consumes most of brain energy, likely creating and maintaining a reserve of general brain functionality. The latent reserve if it exists may be reflected by the profound long-range fluctuations of resting brain activity. link3 The long-range temporal coherence (LRTC) can be characterized by resting state fMRI (rsfMRI)-based brain entropy (BEN) mapping. While BEN mapping results have shown sensitivity to neuromodulations or disease conditions, the underlying neuromechanisms especially the associations of BEN or LRTC to neurocognition still remain unclear. To address this standing question and to test a novel hypothesis that resting BEN reflects a latent functional reserve through the link to general functionality, we mapped resting BEN of 862 young adults and comprehensively examined its associations to neurocognitions using data from the Human Connectome Project (HCP). Our results unanimously highlighted two brain circuits the default mode network (DMN) and executive control network (ECN) through their negative associations of BEN to general functionality, which is independent of age and sex. While BEN in DMN/ECN increases with age, it decreases with education years. These results demonstrated the neurocognitive correlates of resting BEN in DMN/ECN and suggest resting BEN in DMN/ECN as a potential proxy of the latent functional reserve that facilitates general brain functionality and may be enhanced by education.Myelin water imaging techniques based on multi-compartment relaxometry have been developed as an important tool to measure myelin concentration in vivo, but are limited by the long scan time of multi-contrast multi-echo acquisition. In this work, a fast imaging technique, termed variable flip angle Echo Planar Time-Resolved Imaging (vFA-EPTI), is developed to acquire multi-echo and multi-flip-angle gradient-echo data with significantly reduced acquisition time, providing rich information for multi-compartment analysis of gradient-echo myelin water imaging (GRE-MWI). The proposed vFA-EPTI method achieved 26 folds acceleration with good accuracy by utilizing an efficient continuous readout, optimized spatiotemporal encoding across echoes and flip angles, as well as a joint subspace reconstruction. An approach to estimate off-resonance field changes between different flip-angle acquisitions was also developed to ensure high-quality joint reconstruction across flip angles. The accuracy of myelin water fraction (MWF) estimate under high acceleration was first validated by a retrospective undersampling experiment using a lengthy fully-sampled data as reference. Prospective experiments were then performed where whole-brain MWF and multi-compartment quantitative maps were obtained in 5 min at 1.5 mm isotropic resolution and 24 min at 1 mm isotropic resolution at 3T. Additionally, ultra-high resolution data at 600 µm isotropic resolution were acquired at 7T, which show detailed structures within the cortex such as the line of Gennari, demonstrating the ability of the proposed method for submillimeter GRE-MWI that can be used to study cortical myeloarchitecture in vivo.
The technical conduct of total laparoscopic hysterectomy (LH) is critical to surgical outcomes. This study explored the validity evidence of an objective scale specific to the assessment of technical skills (H-OSATS) for 7 tasks of an LH with salpingo-oophorectomy procedure performed in the operating room.
Observational cohort study.
Two academic hospitals in Marseille and Montpellier, France.
Three groups of operators (novice, intermediate, and experienced surgeons) were video recorded during their live performances of LH on a simple case. For each group, a dozen unedited videos were obtained for the following tasks division of the round ligament, division of the infundibulopelvic ligament, creation of the bladder flap, opening of the posterior peritoneum, division of the uterine vessels, colpotomy, and closure of the vault.
Two qualified raters blindly assessed each video using the H-OSATS rating scale. Inter-rater reliability and test-retest reliability were calculated as measures of internal structure.
