BACKGROUND Septopreoptic holoprosencephaly is a mild form of holoprosencephaly in which the midline non-separation is restricted to the septal or preoptic regions. This entity has only been described in a small case series in which associated intracranial abnormalities were limited to the midline structures. OBJECTIVE To describe the radiologic findings of septopreoptic holoprosencephaly and highlight that it can be associated with a variety of intracranial abnormalities, not merely with abnormalities restricted to midline structures as previously reported. MATERIALS AND METHODS We retrospectively identified 22 children whose MRIs were confirmed to have non-separation restricted to the septal and preoptic region, fulfilling the criteria for septopreoptic holoprosencephaly. We then categorized MRIs as having, in addition, either intracranial abnormalities limited to the midline structures or major abnormalities not limited to the midline structures. RESULTS Five children had intracranial abnormalities limited to the midline structures. Seventeen children had major intracranial abnormalities not limited to the midline structures. The major abnormalities included patterning defects of the midbrain-hindbrain (elongated midbrain, shortened pons, shortened/elongated medulla, partial rhombencephalosynapsis), bilateral perisylvian polymicrogyria, microcephaly, megalencephaly and a spheno-ethmoidal encephalocele. Recognized syndromes/chromosomal abnormalities were also observed in this patient group. CONCLUSION Our results suggest that septopreoptic holoprosencephaly has been under-recognized and under-reported to date. We propose that searching for this anomaly should be part of the complete assessment of the midline in all children undergoing brain MRI for intracranial malformations.Rehospitalization following pediatric heart transplantation is common. Fluorouracil However, existing data remain somewhat limited. Using a novel linkage between administrative and clinical databases, pediatric heart transplant (HT) recipients from 29 centers who survived to discharge were retrospectively reviewed to determine the frequency, timing of, and indication for all-cause rehospitalizations in the year following transplant discharge. Of 2870 pediatric HT recipients, 1835 (63.9%) were rehospitalized in the first year post-discharge (5429 total readmissions). Rehospitalization rates varied significantly across centers (46% to 100%) and were inversely correlated to center transplant volume (r2 0.25, p  less then  0.01). The median number of rehospitalizations per patient was 2 (IQR 1-4) and the median time to first rehospitalization was 29 days (IQR 9-99 days). Independent risk factors for rehospitalization included younger age at HT (HR 0.99, 95% CI 0.97-0.99), congenital heart disease (HR 1.2, 95% CI 1.1-1.4), listing status 1B at transplant (HR 1.3, 95% CI 1.1-1.5), and post-transplant complications including rejection prior to discharge (HR 1.5 95% CI 1.3-1.8) and chylothorax (HR 1.3, 95% CI 1.0-1.6). Cardiac diagnoses were the most common indication for rehospitalization (n = 1600, 29.5%), followed by infection (n = 1367, 25.2%). These findings may serve to guide the development of interventions aimed at reducing post-HT hospitalizations.INTRODUCTION Robot-assisted simple prostatectomy (RASP) is a relatively new minimally invasive procedure for surgical treatment to manage symptomatic, therapy-refractory benign prostate hyperplasia (BPH) in prostate volumes >80 cm3. Thus, postoperative morbidity based on Clavien-Dindo and hematological parameters in RASP and open simple prostatectomy (OSP) procedures are examined. PATIENTS AND METHODS We retrospectively reviewed a total of 78 patients 39 patients underwent RAPS and 39 OSP. The following parameters were statistically evaluated and compared age, PSA value, prostate volume, ASA score, duration of hospital stay, operative time, Hb decrease on postoperative (po) day 1 and in the 5 five po days, CRP peak in the first 5 po days and transfusion rate. RESULTS The comparison between RASP and standard OSP showed no significant differences regarding the mean patient age (73 vs. 74 years; p =0.54), PSA values (7.7 vs. 10.7 ng/ml; p =0.17), ASA score (2.2 vs. 2.3; p =0.26) and prostate volume (130 vs. 113 cm3; p =0.07). Patients in the RAPAE group had statistically significant longer surgery (178 vs. 110 min; p = less then 0.01) with a significantly smaller decrease in Hb on po day 1 (1.9 vs. link2 3.3 g/dl; p ≤0.01) and in the first 5 po days (2.4 vs. 4.2 g/dl; p ≤0.01), lower need for preserved blood (3% vs. 26%; p =0.01) and number of blood bags (0.1 vs. 1.3; p =0.01), a lower po Clavien-Dindo score (0.44 vs. 1.23; p =0.003) and lower CRP values (52 vs. 104 mg/l; p ≤0.01) in the first 5 po days. CONCLUSION RASP is a safe procedure that offers the advantage of reduced blood loss and blood bag consumption and rare complications due to the minimally invasive surgical method. The OSP group showed an increased occurrence of complications due to bleeding, leading to prolonged hospitalization and significantly increased need for blood transfusion. The lesser increase of CRP in RASP group is a result of the lower invasiveness of the robot-assisted procedure.Distraction osteogenesis (DO) is a clinically effective procedure to regenerate large bone defects. However, the treatment duration is undesirably lengthy, especially in elderly patients. Exosomes derived from mesenchymal stem cells (MSC-Exos) could exert the beneficial effects while avoiding the possible complications of stem cell transplantation. This study aimed to evaluate the effects of MSC-Exos on bone regeneration during DO in older rats. Exosomes were isolated from the supernatants of young bone marrow mesenchymal stem cells (BMSCs) through ultra-centrifugation, and characterized using transmission electron microscopy, western blot, and tunable resistive pulse sensing analysis. The effects of MSC-Exos on the proliferation and differentiation of older BMSCs were evaluated using CCK-8 assay, ALP and ARS staining, and qRT-PCR. Unilateral tibial DO model was established on older Sprague-Dawley rats and MSC-Exos or phosphate buffer saline was locally injected into the distraction gaps after distraction weekly. Bone regeneration were evaluated using X-ray, Micro-CT, mechanical test, and histological staining. The MSC-Exos were round or cup-shaped vesicles ranging from 60 to 130 nm in diameter and expressed markers including CD9, CD63, and TSG101. The in vitro results indicated that MSC-Exos could enhance the proliferation and osteogenic differentiation of older BMSCs. Bone regeneration was markedly accelerated in rats treated with MSC-Exos according to the results of X-ray, micro-CT, and histological analysis. The distracted tibias from the MSC-Exos group also demonstrated better mechanical properties. link3 These results suggest that MSC-Exos promote DO-mediated bone regeneration in older rats through enhancing the proliferation and osteogenic capacity of BMSCs.A Gram-negative and facultative anaerobic bacterium, designated strain SN4T, was isolated from the stool sample of an obese Amazonian patient. The new isolate was characterized by the taxonogenomics approach. The strain SN4T was beige-colored, circular and not haemolytic. Cells are rod shaped and motile with several flagella. Strain SN4T grows optimally at pH 7 and can survive in the presence of a saline concentration of up to 75 g/l NaCl. The 16S ribosomal RNA gene sequence analysis of the novel strain SN4T showed 95.28% similarity in nucleotide sequence with Gorillibacterium massiliense G5T, the phylogenetically closest neighbor and the type species of this genus. Anteiso-C150, iso-C150 and C160 were found as the major components in the cellular fatty acid analysis of this isolate. The genomic draft of strain SN4T is 5,263,742 bp long with 53.33% of G+C content. The differences in physiological, biochemical characteristics and phylogenetic and genomic data make it possible to clearly distinguish the strain SN4T from G. massiliense G5T. Based on the taxonogenomic description and the phenotypic and biochemical characteristics of this bacterium presented in this article, we propose the SN4T strain (= CSUR P2011 = DSM 100,698) as a new species, Gorillibacterium timonense sp. nov.RATIONALE Cue avoidance training (CAT) reduces alcohol consumption in the laboratory. However, the neural mechanisms that underlie the effects of this intervention are poorly understood. OBJECTIVES The present study investigated the effects of a single session of CAT on event-related and readiness potentials during preparation of approach and avoidance movements to alcohol cues. METHODS Heavy drinking young adults (N = 60) were randomly assigned to complete either CAT or control training. After training, we recorded participants' event-related and motor readiness potentials as they were preparing to respond. RESULTS In the CAT group, N200 amplitude was higher when preparing to approach rather than avoid alcohol pictures. In the control group, N200 amplitudes did not differ for approach and avoidance to alcohol pictures. Regarding the late positive potential (LPP), in the CAT group, the negativity of this was blunted when preparing to avoid alcohol pictures relative to when preparing to avoid control pictures. In the control group, the negativity of the LPP was blunted when preparing to approach alcohol pictures relative to when preparing to approach control pictures. There were no effects on motor readiness potentials. Behavioural effects indicated short-lived effects of training on reaction times during the training block that did not persist when participants were given time to prepare their motor response before executing it during the EEG testing block. CONCLUSIONS After a single session of CAT, the enhanced N200 when approaching alcohol cues may indicate the engagement of executive control to overcome the associations learned during training. These findings clarify the neural mechanisms that may underlie the effects of CAT on drinking behaviour.Chronic kidney disease (CKD)-related osteoporosis is a major complication in patients with CKD, conferring a higher risk of adverse outcomes. We found that among those with diabetic kidney disease, this complication increased the risk of incident frailty, an important mediator of adverse outcomes. INTRODUCTION Renal osteodystrophy and chronic kidney disease (CKD)-related osteoporosis increases complications for patients with diabetic kidney disease (DKD). Since musculoskeletal degeneration is central to frailty development, we investigated the relationship between baseline osteoporosis and the subsequent frailty risk in patients with DKD. METHODS From the Longitudinal Cohort of Diabetes Patients in Taiwan (n = 840,000), we identified 12,027 patients having DKD with osteoporosis and 24,054 propensity score-matched controls having DKD but without osteoporosis. The primary endpoint was incident frailty on the basis of a modified FRAIL scale. Patients were prospectively followed-up until the development of endpoints or the end of this study. The Kaplan-Meier technique and Cox proportional hazard regression were used to analyze the association between osteoporosis at baseline and incident frailty in these patients. RESULTS The mean age of the DKD patients was 67.2 years, with 55.4% female and a 12.6% prevalence of osteoporosis at baseline. After 3.5 ± 2.2 years of follow up, the incidence rate of frailty in patients having DKD with osteoporosis was higher than that in DKD patients without (6.6 vs. 5.7 per 1000 patient-year, p = 0.04). A Cox proportional hazard regression showed that after accounting for age, gender, obesity, comorbidities, and medications, patients having DKD with osteoporosis had a significantly higher risk of developing frailty (hazard ratio, 1.19; 95% confidence interval, 1.02-1.38) than those without osteoporosis. CONCLUSIONS CKD-related osteoporosis is associated with a higher risk of incident frailty in patients with DKD.
