0-50 μM with a detection limit of 0.1 μM. The electrode revealed good storage stability, reproducibility, and anti-interference ability. The determination of nitrite performed in curing salts brought satisfactory results.Prefrontal cortical regions play a key role in behavioural regulation, which is profoundly disturbed in suicide. The study was carried out on frozen cortical samples from the anterior cingulate cortex (dorsal and ventral parts, ACd and ACv), the orbitofrontal cortex (OFC), and the dorsolateral cortex (DLC) obtained from 20 suicide completers (predominantly violent) with unknown psychiatric diagnosis and 21 non-suicidal controls. The relative level of ribosomal RNA (rRNA) as a marker of the transcriptional activity of ribosomal DNA (rDNA) was evaluated bilaterally in prefrontal regions mentioned above (i.e. in eight regions of interest, ROIs) by reverse transcription and quantitative polymerase chain reaction (RT-qPCR). The overall statistical analysis revealed a decrease in rDNA activity in suicide victims versus controls, particularly in male subjects. Metabolism agonist Further ROI-specific post hoc analyses revealed a significant decrease in this activity in suicides compared to non-suicides in five ROIs. This effect was accentuated in the ACv, where it was observed bilaterally. Our findings suggest that decreased rDNA transcription in the prefrontal cortex plays an important role in suicide pathogenesis and corresponds with our previous morphometric analyses of AgNOR-stained neurons.

To assess the feasibility of total shoulder denervation through two proposed incisions.

Total shoulder denervation was performed through an extended delta-pectoral approach and a transverse dorsal approach at the spine of the scapula. The studyinvolved six cadavers. Course and number of articular branches from the lateral pectoral, axillary and supra-scapular nerve were documented.

All shoulder joint articular branches were accessible through the proposed anterior and posterior approaches. The articular branch of the lateral pectoral nerve and suprascapular nerve were present in all the specimen. Axillary nerve articular branches were variable in number but when present anteriorly were proximal to the deltoid muscularbranches and posteriorly proximal to the muscular branches to the teres minor.

Total glenohumeral denervation was feasible through our proposed anterior and posterior approaches. Enhanced knowledge of articular nerve branches could provideinterventional targets for joint and ligament pain, with low risk of muscle weakness.

Cardiotoxicity can occur acutely during breast cancer treatment and impact the potential for the intended cancer treatment regime to be completed, or as a late effect affecting cancer survivorship. Indeed, the most common cause of mortality in females with early breast cancer is cardiovascular disease, especially in those over the age of 65. Optimal cancer care therefore needs to be delivered without jeopardising cardiovascular health. Understanding the different cardiotoxicities associated with breast cancer treatment is vital to this approach, and therefore, this article seeks to provide an overview of this.

Tyrosine kinase inhibitors targeting human epidermal growth factor receptor (HER)-2, immune checkpoint inhibitors (ICI), and cyclin-dependent kinase (CDK) inhibitors are new targeted breast cancer treatments. In particular, ICI are associated with myocarditis that carries a significant mortality, whilst the CDK inhibitor ribociclib causes QT prolongation that requires cardiac surveillance and approp appropriate dose adjustment to prevent ventricular arrhythmias. The need has always been for strategies to mitigate the risks of cardiovascular toxicities, and new data is promising for the use of dexrazoxane in anthracyclines, and the role of beta blockers and angiotensin converting enzymes inhibitors in anthracyclines and HER-2 monoclonal antibodies such as trastuzumab. Significant headways in breast cancer treatment have resulted in reductions in disease recurrence and mortality, but cardiovascular complications continue to impact the ability to deliver some of these cancer treatments, and the period of cancer survivorship.

Hospitalized coronavirus disease 2019 (COVID-19)patients have ahigh morbidity and mortality and are often dependent on intensive care, especially mechanical ventilation. Little is as yet known about COVID-19patient allocation.

Analysis of the structures of German hospital care for COVID-19patients up to July 2020 in terms of number of beds and previous ventilation experience.

For the analysis of the care structures, only completed COVID-19cases in which the virus was detected by aPCR test were evaluated. Claims data from the German Local Health Care Funds (Allgemeine Ortskrankenkassen, AOK) were analysed. The sample includes 17,094COVID-19cases that were treated in 1082hospitals.

A total of 77% of all hospitals participated in the treatment COVID-19patients and 48% of all hospitals provided intensive care for these patients. One half of the hospitals that treated COVID-19cases cared for 88% of all cases. Although this suggests acentralization effect of COVID-19cases in specific hospitals, the remaininyramid-type concept with a greater concentration in the best-qualified hospitals seems reasonable for the care of these patients with complex diseases.

Minimally invasive, sufficiently stable for movement and partial weight bearing, osteosythesis of pertrochanteric femoral fractures in children < 6-8years using elastic, stable intramedullary nailing (ESIN).

Proximal, pertrochanteric femoral fractures Delbet typeIV in children < 6years.

Comminuted fractures, femoral neck fractures.

By inserting three elastic titanium nails (TEN), prebent in the proximal third, retrograde into the femur, astable 3‑point support stabilizes the proximal fragment. For further improvement of stability, EndCaps can be used.

Partial weight bearing (sole-contact) for 4-5weeks. X‑ray controls immediately after surgery and after 4-5weeks. No sports for 3months.

In our patient population we have good experience with this technique for very rare pertrochanteric fractures in children younger than 6-8years. With minimally invasive access, exercise-stable administration can be achieved without apelvic leg cast.

Accurate brain tumor segmentation on magnetic resonance imaging (MRI) has wide-ranging applications such as radiosurgery planning. Advances in artificial intelligence, especially deep learning (DL), allow development of automatic segmentation that overcome the labor-intensive and operator-dependent manual segmentation. We aimed to evaluate the accuracy of the top-performing DL model from the 2018 Brain Tumor Segmentation (BraTS) challenge, the impact of missing MRI sequences, and whether a model trained on gliomas can accurately segment other brain tumor types.

We trained the model using Medical Decathlon dataset, applied it to the BraTS 2019 glioma dataset, and developed additional models using individual and multimodal MRI sequences. The Dice score was calculated to assess the model's accuracy compared to ground truth labels by neuroradiologists on BraTS dataset. The model was then applied to a local dataset of 105 brain tumors, performance of which was qualitatively evaluated.

The DL model using pre- and post-gadolinium contrast T1 and T2 FLAIR sequences performed best, with a Dice score 0.878 for whole tumor, 0.732 tumor core, and 0.699 active tumor. Lack of T1 or T2 sequences did not significantly degrade performance, but FLAIR and T1C were important contributors. All segmentations performed by the model in the local dataset, including non-glioma cases, were considered accurate by a pool of specialists.

The DL model could use available MRI sequences to optimize glioma segmentation and adopt transfer learning to segment non-glioma tumors, thereby serving as a useful tool to improve treatment planning and personalized surveillance of patients.

This study was to investigate the effect of mesorectal fat tissue volume (MRV) on the pathological response to neoadjuvant chemoradiotherapy (nCRT) in patients with locally advanced rectal cancer.

88 patients who had been diagnosed with locally advanced rectal cancer between January 2017 and June 2020 were reviewed retrospectively. The total abdominal, subcutaneous, visceral, and mesorectal fatty tissue components were measured semiquantitatively by two radiologists using computed tomography (CT)-based findings. The patients were divided into two groups as those with and without a pathological response to nCRT. The relationship of MRV with the other fat tissue components of the body was also evaluated.

We performed a retrospective analysis of 88 patients (mean age 62.7years [range, 33-90years]; 31 males and 57 females). A positive response to nCRT was present in 47 patients. There were 59 patients with stage 3 disease. 46 patients demonstrated lymph node involvement. The mean MRV was 69.6 ± 31.0ml in no. There was a negative correlation between the MRV and the N stage. A cut-off value of ≥ 69.4 for MRV predicted the repsonse to nCRT, with 82.9% sensitivity and 58.5% specificity [AUC 0.757 (0.653-0.842), p  less then  0.001] in receiver operating characteristic (ROC) curve analysis CONCLUSIONS MRV can be used as a novel parameter in predicting of pathological response to nCRT in locally advanced rectal cancer patients.

No difference between both hands was observed for clinical and radiographical presentations in EHOA patients. A bilateral and symmetrical relationship was found between hand joints.

EHOA have symmetrical distribution and specific association in structural lesions. This study aims to analyse the preferential topographical distribution of clinical and structural lesions between the dominant and non-dominant hands in erosive hand osteoarthritis (EHOA) patients. Both hands were assessed via radiography in EHOA patients. A comparative analysis of the clinical features and structural lesions between the dominant and non-dominant hands was performed. The structural lesions were assessed according to the anatomical radiographic score of Verbruggen-Veys (VV). Next, a principal component analysis was performed to describe and highlight the relationships observed between the joints. Sixty patients were included in this study there were 57 women, and the mean age was 66.1 (± 7.6) years. For the distal interphalangeal (DIP) joints, nodes were observed more frequently on the dominant hand (4 vs 3; p = 0.
