The use of osteobiologics, engineered materials designed to promote bone healing by enhancing bone growth, is becoming increasingly common for spinal fusion procedures, but the efficacy of some of these products is unclear. The authors performed a retrospective, multi-institutional study to investigate the clinical and radiographic characteristics of patients undergoing single-level anterior cervical discectomy with fusion performed using the osteobiologic agent Osteocel, an allograft mesenchymal stem cell matrix.<br /><br /> The medical records across 3 medical centers and 12 spine surgeons were retrospectively queried for patients undergoing single-level anterior cervical discectomy and fusion (ACDF) with the use of Osteocel. Pseudarthrosis was determined based on CT or radiographic imaging of the cervical spine. Patients were determined to have radiographic pseudarthrosis if they met any of the following criteria 1) lack of bridging bone on CT obtained &gt; 300 days postoperatively, 2) evidence of instrumentation versus 8.4% for patients with allograft implants (p = 0.04). Average lengths of follow-up were 27.6 and 23.8 months for patients with and those without pseudarthrosis, respectively. Multivariate analysis demonstrated osteopenia or osteoporosis (OR 4.97, 95% CI 1.51-16.4, p &lt; 0.01) and usage of PEEK implant (OR 2.24, 95% CI 1.04-4.83, p = 0.04) as independent predictors of pseudarthrosis.<br /><br /> In patients who underwent single-level ACDF, rates of pseudarthrosis associated with the use of the osteobiologic agent Osteocel are higher than the literature-reported rates associated with the use of alternative osteobiologics. This is especially true when Osteocel is combined with a PEEK implant.<br /><br />In patients who underwent single-level ACDF, rates of pseudarthrosis associated with the use of the osteobiologic agent Osteocel are higher than the literature-reported rates associated with the use of alternative osteobiologics.

Chaihuang granules (CHG), as a well-known TCMP, consists of Chaihu (Bupleuri Radix) and Huangqin (Scutellariae Radix) extract. In this work, we used pharmacokinetics and metabolomics to evaluate consistency of CHG products from two different manufacturers. In the pharmacokinetic study, a liquid chromatography tandem mass spectrometry (LC-MS/MS) method was applied to determine the plasma concentration-time profiles of baicalin in rat plasma. Pharmacokinetic parameters, including the maximum concentration in blood (Cmax), area under the curve (AUC), the time to reach Cmax (Tmax), and half-life (T1/2), were calculated to assess the consistency preliminarily. And there was no significant difference in these pharmacokinetic parameters between the two CHG. In LC-MS-based metabolomics, the metabolic response profiles changes based on relative distance values (RDV) to different CHG products were compared. Meanwhile, the kinetic process of 31 differential endogenous metabolites that altered by CHG were determined. Metabolomics data showed the similar metabolic regulation effects to rats of the two formulations. Both pharmacokinetic and metabolomics results indicated there was no significant difference between CHG products. Furthermore, metabolic pathways significantly altered by CHG were elucidated, including phenylalanine, tyrosine and tryptophan biosynthesis, valine, leucine and isoleucine biosynthesis, phenylalanine metabolism, and sphingolipid metabolism. Pharmacokinetics combined with metabolomics could provide a comprehensive perspective for consistency evaluation of CHG.<br /><br /> Several studies have investigated the association between erectile dysfunction (ED), its treatment, and female sexual dysfunction, but the impact of males blaming their female partners for their ED remains unknown.<br /><br /> To investigate whether women who are blamed by their male partners for their ED experience worse overall sexual function and satisfaction.<br /><br /> We performed a global, cross-sectional web-based survey to investigate female perceptions of ED. We distributed the 30-item survey via email, Reddit, Amazon Mechanical Turk, and Facebook. Women 18 years of age or older were eligible to participate and answered questions based on a 5-point Likert scale. Women were grouped by ages 18-29, 30-39, and 40 and older.<br /><br /> The survey collected data that included general demographics and questions regarding experiencing male blame for ED and its relationship with each subject's sexual health and wellness.<br /><br /> A total of 13,617 females participated in the survey. Of the women surveyed, 79% have experienced their partner male blame for their partner's ED which is associated with negative impacts on female mental health, sexual satisfaction and the success of the overall partnership. Because of its widespread impact on female wellness, male blame should be considered during evaluation of female sexual history and men must be educated on the significant impact their reactions during intimacy have on their female partners and their relationships as a whole.

Clinical features, perioperative assessment, time from injury to surgery, tunica defect properties, and presence of urethral injury were assessed.<br /><br /> Sexual function was evaluated by three parameters six months after surgical repair International Index of Erectile Function-5 (IIEF-5) questionnaire, penile curvature and the presence of a painful intercourse. All factors that could potentially influence these parameters were analyzed.<br /><br /> The mean age was 31.2 years (19-55). Presentation delay ranged from 1 to 5 days (mean=16.8 hours) while surgery delay was 14.3 hours ().The most common cause of penile fracture in our e incidence of ED after surgical repair of penile fractures.

Sex Med 2021;9100353.<br /><br /> Over the past decade, convolutional neural networks (CNNs) have revolutionized the field of medical image segmentation. Prompted by the developments in computational resources and the availability of large datasets, a wide variety of different two-dimensional (2D) and three-dimensional (3D) CNN training strategies have been proposed. However, a systematic comparison of the impact of these strategies on the image segmentation performance is still lacking. Therefore, this study aimed to compare eight different CNN training strategies, namely 2D (axial, sagittal and coronal slices), 2.5D (3 and 5 adjacent slices), majority voting, randomly oriented 2D cross-sections and 3D patches.<br /><br /> These eight strategies were used to train a U-Net and an MS-D network for the segmentation of simulated cone-beam computed tomography (CBCT) images comprising randomly-placed non-overlapping cylinders and experimental CBCT images of anthropomorphic phantom heads. The resulting segmentation performances were quantitatively compared by calculating Dice similarity coefficients. In addition, all segmented and gold standard experimental CBCT images were converted into virtual 3D models and compared using orientation-based surface comparisons.<br /><br /> The CNN training strategy that generally resulted in the best performances on both simulated and experimental CBCT images was majority voting. When employing 2D training strategies, the segmentation performance can be optimized by training on image slices that are perpendicular to the predominant orientation of the anatomical structure of interest. [https://www.selleckchem.com/ALK.html ALK inhibitor] Such spatial features should be taken into account when choosing or developing novel CNN training strategies for medical image segmentation.<br /><br /> The results of this study will help clinicians and engineers to choose the most-suited CNN training strategy for CBCT image segmentation.<br /><br />The results of this study will help clinicians and engineers to choose the most-suited CNN training strategy for CBCT image segmentation.<br /><br /> Clinical decision support systems (CDSSs) are developed to support healthcare practitioners with decision-making about therapy and diagnosis' confirmation, among others. Although there are many advantages of using CDSSs, there are still many challenges in their adoption. Therefore, it is essential to ensure the quality of the system, so that it can be used confidently and securely.<br /><br /> This study aims to propose a set of (sub)characteristics which should be considered in evaluating the quality-in-use of CDSSs, based on the ISO/IEC 25010 standard and on existing literature.<br /><br /> We reviewed the existing literature on CDSS assessment and presented a list of quality characteristics evaluated.<br /><br /> Ten quality characteristics and 56 sub-characteristics were identified and selected from the literature, in which usability was evaluated the most. An example of a scenario has been presented to illustrate our assessment approach of satisfaction and efficiency as important quality-in-use characteristics to be applied in the evaluation of a CDSS.<br /><br /> The proposed approach will contribute in bridging the gap between the quality of CDSSs and their adoption.<br /><br />The proposed approach will contribute in bridging the gap between the quality of CDSSs and their adoption.The intestine is a vital organ mediating absorption of nutrients and water. Following tissue damage, the intestine mounts a remarkable regenerative response by reprogramming cellular identity to facilitate reinstatement of homeostasis. Here we review recent advances within intestinal regenerative biology and the emerging concept of fetal-like reprogramming, in which the adult intestinal epithelium transiently enters a repair-associated state reminiscent of ontologically pre-existing stages. We focus on molecular mechanisms governing reprogramming of cellular identity via epithelial-mesenchymal crosstalk, and how novel approaches in organoid technologies enable identification and characterisation of cell-autonomous repair responses within epithelial cells. Transitioning from the single-cell level to tissue scale, we discuss clonal selection following regeneration and associated pathological repurcussions such as cancer and chronic inflammatory diseases.Diabetes is a group of metabolic disorders, which results from insufficient functional pancreatic β-cell mass either due to the autoimmune destruction of insulin producing β-cells, or their death or de-differentiation as compensation for insulin resistance. The ability to reprogram cell types within close developmental proximity to β-cells offers a strategy to replenish β-cell mass and a future possible treatment of diabetes. Here, we review recent advances in the fields of pancreas development and lineage reprogramming. We also probe the possibility of using reprogrammed cells as an approach by which to further understand developmental mechanisms, in particular roadblocks to changing cell identity. Finally, we highlight fundamental challenges that need to be overcome to advance lineage reprogramming for generating pancreatic cells.
