To cross the outer membrane of the complex Gram-negative cell envelope, antibiotics permeate through porins, trimeric channel proteins that enable the exchange of small polar molecules. Mutations in porins contribute to the development of drug-resistant phenotypes. In this work, we show that a single point mutation in the porin PorB from Neisseria meningitidis, the causative agent of bacterial meningitis, can strongly affect the binding and permeation of beta-lactam antibiotics. Using X-ray crystallography, high-resolution electrophysiology, atomistic biomolecular simulation, and liposome swelling experiments, we demonstrate differences in drug binding affinity, ion selectivity and drug permeability of PorB. Our work further reveals distinct interactions between the transversal electric field in the porin eyelet and the zwitterionic drugs, which manifest themselves under applied electric fields in electrophysiology and are altered by the mutation. These observations may apply more broadly to drug-porin interactions in other channels. check details Our results improve the molecular understanding of porin-based drug-resistance in Gram-negative bacteria.Familial hypercholesterolemia (FH) is one of the most common genetic disorders in humans. It is an extremely atherogenic metabolic disorder characterized by lifelong elevations of circulating LDL-C levels often leading to premature cardiovascular events. In this review, we discuss the clinical phenotypes of heterozygous and homozygous FH, the genetic variants in four genes (LDLR/APOB/PCSK9/LDLRAP1) underpinning the FH phenotype as well as the most recent in vitro experimental approaches used to investigate molecular defects affecting the LDL receptor pathway. In addition, we review perturbations in the metabolism of lipoproteins other than LDL in FH, with a major focus on lipoprotein (a). Finally, we discuss the mode of action and efficacy of many of the currently approved hypocholesterolemic agents used to treat patients with FH, with a special emphasis on the treatment of phenotypically more severe forms of FH.
Survival after bridge to transplant with mechanical circulatory support (MCS) has yielded varying outcomes based on device type and baseline characteristics Continuous flow left ventricular assist devices (CF-LVADs) have significantly improved waitlist mortality, but recent changes to the transplant listing criteria have dramatically altered the use of MCS for bridge to transplant.

Orthotopic heart transplants from 1988-2019 at our institution were retrospectively reviewed and stratified by pre-transplant MCS status into CF-LVAD (n=224), Pulsatile LVAD (n=49), temporary MCS (n=71), and primary transplant (n=463) groups. Patients transplanted after the approval of CF-LVAD for bridge to transplant and before the 2018 allocation policy changes underwent subgroup analysis to evaluate predictors of survival and complications in a contemporary cohort.

Rates of primary transplant declined from 88% to 14% over the course of the study. No significant difference in survival was detected in the cohort stratified by MCS status (P=0.18). In the modern era, survival for CF-LVAD and temporary MCS patients was non-inferior to primary transplant (P=0.22). Notable predictors of long-term mortality included lower body mass index, peripheral vascular disease, prior coronary artery bypass graft, ABO non-identical transplant, and increased donor age (all P<0.02). There were no differences in major postoperative complications.

CF-LVAD has grown to account for the majority of transplants at our center in the last decade with no adverse effect on survival or postoperative complications. Temporary MCS has increased following the 2018 listing criteria change with acceptable early outcomes.

Video-assisted thoracoscopic surgery (VATS) for internal fixation of rib fracture is a promising approach for treating rib fractures and flail chest. link= check details Currently, the standard practice is to make one or several incisions on the chest wall, which will inevitably aggravate the original trauma.

We retrospectively analyzed the data of patients with rib fractures who were treated with memory alloy for internal fixation by complete VATS using a thoracoscopic transthoracic memory alloy rib coaptation board and an implantation tool through the clip applier method or the puncture, traction and suspension method at our hospital from October 2016 to June 2019.

There were 35 patients, of whom 12 had traumatic flail chest injury, and 23 had simple multiple rib fractures. Of the 23 patients with multiple rib fractures, 9 had fracture ends in the scapular or paravertebral region, and 14 had fracture ends located in the anterior or lateral chest walls. All surgeries were performed with complete VATS, and it showed quick recovery and good thoracic appearance and function, with no complications for all patients. Follow-up for 6-24 months revealed no detachment of the internal fixation device.

Internal memory alloy fixation with complete VATS for the treatment of rib fractures is a simple and minimally invasive method, which enables fixing fractured ribs internally while treating thoracic trauma with a thoracoscope.

Internal derangement and osteoarthritis are the most common degenerative temporomandibular joint diseases and initial treatment for such conditions relies on arthrocentesis. Microfragmentation of adipose tissue has been proven in orthopedic literature to represent a more effective method to preserve stem cells, but no application has ever been reported in the temporomandibular joint. The purpose of this randomized clinical trial is to compare standard treatment conducted by injecting hyaluronic acid after the procedure to the new treatment relying upon microfragmented adipose tissue injection using the Lipogems technology.

A randomized clinical trial was designed enrolling 20 patients in the control group receiving the standard treatment and 20 patients in the experimental group receiving microfragmented adipose tissue obtained through the Lipogems technology after arthrocentesis. Two main outcomes were defined, pain (visual analogic scale) and function (maximum interincisal opening). Both were measured if this clinical trial show that the injection of microfragmented adipose tissue can significantly improve outcomes of pain and function compared with the standard treatment and encourage to pursue research on this topic. Further studies with a longer follow-up time are needed to evaluate the clinical stability of the achieved improvement in pain and function.
There is no consensus on the impact of red blood cell (RBC) transfusion on patients with oral squamous cell carcinoma (OSCC). The purpose of this study was to investigate the association between RBC transfusions and overall survival (OS) and tumor-free survival (TFS) after operative treatment of OSCC.

In this retrospective cohort study, all patients treated with primary surgery between 2003 and 2017 because of OSCC were chart reviewed. The occurrence and amount of RBC transfusions (0; 1-3; >3 units) was correlated with OS and TFS by Kaplan-Meier survival and Cox regression analyses. check details Demographic, clinical, and pathological parameters were also evaluated in order to identify confounding factors.

Of 420 patients (243 [57.9%] male) with a mean age of 62.6years, 67 (16.0%) received RBC transfusion. There were statistically significant (P<.01) differences in 5-year OS respectively TFS in transfused patients for the Kaplan-Meier survival analysis (0 units=70.6%; [95% confidence interval CI 65.0-75.4%] respectively 63.2% [95% CI 57.4-68.4%], 1-3 units=47.2% [95% CI 29.4-63.1%] respectively 40.6% [95% CI 24.6-55.95%] and >3 units=48.9% [95% CI 20.9-72.1%] respectively 30.5% [95% CI 8.9-55.8%]). After multivariate adjustments for demographic, clinical, and pathological parameters, RBC transfusion could not be sustained as a significant prognostic factor in OS respectively TFS (1-3 units hazard ratio=1.5 [95% CI 0.7-3.2] respectively 1.3 [95% CI 0.7-2.6]; >3 units hazard ratio=1.2 [95% CI 0.5 - 3.0] respectively 1.1 [95% CI 0.5-2.4]).

Although RBC transfusion was not identified as a significant prognostic parameter in multivariate analysis, a clear trend for shorter OS and TFS for transfused patients in univariate and Kaplan-Meier survival analysis could be shown.

An uncommon, but serious complication of endodontic treatment is inferior alveolar nerve (IAN) injury warranting operative intervention for exploration, debridement, and repair. link2 The purpose of the study was to evaluate outcomes of microneurosurgical intervention for endotontic-related IAN injuries in terms of achievement of functional sensory recovery (FSR) and pain relief and to identify factors affecting outcomes.

A retrospective cohort study of patients who had microsurgical exploration and repair of IAN injuries sustained during endodontic therapy was performed. The primary predictor variable is time to surgery and the primary outcome variables were time to FSR, whether or not the patient regained FSR, and postoperative pain level at 12months (1-10 on a visual analog scale). link3 Secondary variables include intraoperative findings, surgical treatment rendered, sensory recovery, and preoperative pain level. Analyses include Kaplan-Meier estimation, Fisher exact test, 1-way and mixed-design analysis of variaevels, while only delivering a modest recovery of sensory function. link2 These injuries can be severe and debilitating and present with a variety of diagnoses and surgical findings. While this study fails to identify any particular factors affecting outcome, the data presented can help with clinician recommendations for treatment in patient-centered care.
To observe the proliferation and differentiation of human adipose-derived stem cells (hADSCs) on 2D and 3D scaffolds, the sodium alginate and collagen interpenetrating network hydrogel were developed to determine optimal properties for bone tissue engineering.

Three groups of scaffold materials were prepared according to the ratio of sodium alginate to collagen A (41), B (21), and C (11), respectively. For each group, gel beads (3D surfaces) and freeze-dried films (2D surfaces) were respectively prepared. link3 For gel beads, hADSCs were mixed during the preparation of the beads, and then stem cells were applied to the surface of each film after freeze-drying and sterilization during the preparation of the freeze-dried films. Cell proliferation and osteogenic differentiation potential were detected by cell counting kit, viable/dead cell staining kit, quantitative reverse transcription polymerase chain reaction, and immunofluorescent staining, respectively.

Results showed that cell proliferation rate progressively increased with the increase of collagen ratio, with group C of 3D surfaces of gel beads achieving the highest rate.
