    In neuromuscular disorders (NMD), inspiratory muscle weakness may cause sleep-related hypoventilation requiring non-invasive ventilation (NIV). Alternatively, nasal high flow therapy (NHF) may ameliorate mild nocturnal hypercapnia (NH) through washout of anatomical dead space and generation of positive airway pressure. Selleck Tetramisole Ventilatory support by NIV or NHF might have favourable short-term effects on sympathovagal balance (SVB). This study comparatively investigated the effects of NHF and NIV on sleep-related breathing and SVB in NMD patients with evolving NH.

    ), peripheral oxygen saturation (SpO

    ), sleep outcomes and SVB (spectral analysis of heart rate, diastolic blood pressure variability) along with haemodynamic measures (cardiac index, total peripheral resistance index) were evaluated overnight in 17 patients. Polysomnographies (PSG) were randomly split into equal parts with no treatment, NIV and NHF at different flow rates (20l/min vs. 50l/min). In-depth analysis of SVB and haemodynamics was performed on 10-min segments of stable N2 sleep taken from each intervention.

    Compared with no treatment, NHF20 and NHF50 did not significantly change p

    or the apnea hypopnea index (AHI). NHF50 was poorly tolerated. In contrast, NIV significantly improved both gas exchange and AHI without adversely affecting sleep. During daytime, NHF20 and NHF50 had neutral effects on ventilation and oxygenation whereas NIV improved p

    NHF does not correct sleep-disordered breathing in NMD patients with NH. Both NHF and NIV exert no immediate effects on SVB.

Therefore, this study aimed to elaborate assessment of physico-chemical characteristics of the Dhaleshwari River (the adjacent river of newly shifted tannery industrial park) and also the discharged effluent from the central effluent treatment plant (CETP) considering both seasonal and spatial variations. Among the examined 30 water quality parameters (including 11 heavy metals), only TDS, Cl-, NO3-N, EC, Cu, Zn, Cd, and Ni met the standards for discharged wastewater from industrial units into inland surface water set by Bangladesh government. This indicated that the CETP is not fully and/or effectively functioning. Out of 19 parameters (excluding heavy metal), 14 parameters exceeded the Bangladesh standard for drinking water quality either spatially or seasonally. The river water quality indicated slowly biodegradable capacity with algal bloom risk. The concentrations of the studied heavy metals in the river water followed a decreasing order of Ca > K > Mg > Na > Fe > Cr > Pb > Ni > Cu > Zn > Cd, and Cr concentration in the winter season exceeded the standard values. The concentrations of other heavy metals met the quality standard that indicated still the river is capable to self-purify. Furthermore, strong (p less then 0.01) and significant (p less then 0.05) correlation were observed among the quality parameters in river water. This study suggested that the efficiency of the existing CETP needs to be enhanced, and the proper operation and maintenance are required to meet the desired discharge standard quality. Also, all the unauthorized wastewater outfalls from tanneries must be closed to save the Dhaleshwari River.

    The aim of this review is to systematically screen the literature for clinical and biomechanical studies dealing with posterior stabilization of acute traumatic mid-thoracic vertebral fractures in patients with normal bone quality.

    This review is based on articles retrieved by a systematic search in the PubMed and Web of Science database for publications up to December 2018 dealing with the posterior stabilization of fractures of the mid-thoracic spine.

    Altogether, 1012 articles were retrieved from the literature search. A total of 960 articles were excluded. A total of 16 articles were dealing with the timing of surgery in polytraumatized patients, patients suffering of neurologic deficits after midthoracic fractures, and the impact of concomitant thoracic injuries and were excluded. Thus, 36 remaining original articles were included in this systematic review depicting the topics biomechanics, screw insertion, and outcome after posterior stabilization. The overall level of evidence of the vast majority of studies is low.

    High quality studies are lacking. Long-segmental stabilization is indicated in unstable midthoracic fractures with concomitant sternal fractures. Generally, long-segmental constructs seem to be the safer treatment strategy considering the relative high penetration rate of pedicle screws in this region. Thereby, navigated insertion techniques and intraoperative 3D-imaging help to improve pedicle screw placement accuracy.

    Lower leg nonunion in pediatric patients is a rarity. Therefore, eight European pediatric trauma units retrospectively analyzed all patients younger than 18years suffering lower leg fractures resulting in aseptic nonunion.

    Thirteen children and adolescents less than 18years old (2 girls and 11 boys) diagnosed with aseptic nonunion of the tibia and/or fibula were evaluated. In all patients, epidemiological data, mechanism of injury, fracture configuration, and the initial treatment concept were assessed, and the entire medical case documentation was observed. Furthermore, potential causes of nonunion development were evaluated.

    The mean age of patients was 12.3years with the youngest patient being seven and the oldest being 17years old. Open fractures were found in six out of thirteen patients (46%). Nonunion was hypertrophic in ten and oligotrophic in three patients. Mean range of time to nonunion occurrence was 7.3 ± 4.6months. Nonunion healing resulting in complete metal removal was found in 12 out of 13 patients (92%), only in one case of a misinterpreted CPT type II osseous consolidation could not be found during the observation period. Mean range of time between surgical nonunion revision and osseous healing was 7.3months as well.

    If treatment principles of the growing skeleton are followed consistently, aseptic nonunion of the lower leg remains a rare complication in children and adolescents. Factors influencing the risk of fracture nonunion development include patient’s age, extended soft tissue damage, relevant bone loss, and inadequate initial treatment.

A total of 72 piglets were weighed and randomly allotted into three treatments (four replication pens per treatment with six piglets/pen) for a 28-day experiment. The dietary treatments were as follows basal diet (control group, CTR), basal diet supplementation with antibiotic (antibiotic group, ABT), and basal diet supplementation with 0.1% Bacillus subtilis (probiotic group, PBT). The average daily gain of body weight increased in both the ABT and PBT groups, and dietary antibiotics decreased the feedgain ratio (FG), as compared to the CTR group (P  less then  0.05). Both ABT and PBT piglets had increased serum triglycerides and lipase, amylase, maltase activities and villus heightcrypt depth ratio (V/C) in ileum (P  less then  0.05). The PBT group also showed an increase in serum glucose and villus height in the ileum (P  less then  0.05). Dietary antibiotics increased Lactobacillus johnsonii, as compared to the CTR group, but decreased bacterial diversity and increased Escherichia coli, as compared to the PBT group (P  less then  0.05). Piglets dietary with B. subtilis modulated the microbiota by increasing the abundance of Firmicutes (L. johnsonii, L. reuteri) and decreasing the abundance of E. coli, as compared to the control group (P  less then  0.05). These results indicate that dietary of B. subtilis improves growth performance and intestinal health and can be a promising alternative to antibiotics in piglets diet.Potamotrygon motoro has been shown to use vision to orient in a laboratory setting and has been successfully trained in cognitive behavioral studies using visual stimuli. This study explores P. motoro’s visual discrimination abilities in the context of two-alternative forced-choice experiments, with a focus on shape and contrast, stimulus orientation, and visual resolution. Results support that stingrays are able to discriminate stimulus-presence and -absence, overall stimulus contrasts, two forms, horizontal from vertical stimulus orientations, and different colors that also vary in brightness. Stingrays tested in visual resolution experiments demonstrated a range of visual acuities from  less then  0.13 to 0.23 cpd under the given experimental conditions. Additionally, this report includes the first evidence for memory retention in this species.

    Testicular type II germ cell tumours (GCTs) are an exemplar of acurable cancer and the most common malignancy in males aged ≤35years. Even in metastatic stages, about 70% of patients can be cured by cisplatin-based chemotherapy and multimodal treatments. For patients failing platinum-based standard therapy, prognosis is poor and novel biomarkers and therapeutic options are urgently needed.

    Discussion of desired histopathological information to guide urologists’ and oncologists’ decision making in the treatment of male GCTs.

    A narrative review of histopathological key features of male GCT tissue samples for clinical decision making.

    Histopathological workup is crucial to identify (i)aGCT origin in cancers of unknown primary based on isochromosome12p (i(12p)) detection, (ii)the different typeII GCT subtypes, and (iii)risk factors, i.e. lymphovascular or rete testis invasion, among others. Proper histopathological diagnosis is indispensable for guideline-endorsed, histology-driven, and risk-adapted treatment decisions, hereby helping to maintain treatment success while reducing the therapeutic burden and potential long-term sequelae of multimodal treatments. For refractory patients failing standard treatment options, prognosis remains poor and, so far, neither predictive or prognostic biomarkers nor novel therapeutic targets have been established.

    Close interaction and interdisciplinary discussion of histopathologic and radiologic findings and established risk factors including serum tumour markers is crucial for successful treatment including intensified strategies, where necessary, or prevention of overtreatment, where possible.
