In this pilot study, we detected highly localized changes in microglial morphology already early after traumatic damage, e.g., activated microglia and phagocyted erythrocytes in the contusion areas in cases with minute survival. Furthermore, an altered antigen expression was observed with increasing trauma wound age, showing similar effects like earlier transcriptomic studies. There is minute data on the direct impact of shear forces on microglial morphology. We were able to show localization-depending effects on microglial morphology causing localized dystrophy and adjacent activation. While rodent studies are widespread, they fail to mimic the exact mechanisms in human TBI response. Therefore, more studies focusing on cadaveric samples need to follow to thoroughly define the mechanisms leading to cell destruction and eventually evaluate their forensic value.The identification of a suspect in a degraded and unbalanced DNA mixture has been a challenge for the standard short tandem repeat polymorphisms (STR) typing. Several methods have been introduced to solve this problem, such as DIP-STR, DIP-SNP, and SNP-STR markers. In this study, we proposed DIP-microhaplotype (deletion/insertion linked a chain of SNPs) as a kind of new genetic marker to type the unbalanced and degraded DNA mixture. We established the detection method with ten DIP-microhaplotype markers including 26 SNPs using allele-specific multiplex PCR followed by SNaPshot assay. This novel compound marker allows us to detect the minor DNA with a sensitivity of 1100 to 11000 in a DNA mixture of any gender. Most of the DIP-microhaplotype markers had a relatively high probability of informative alleles with an average informative value (I value) of 0.308. In all, we proposed DIP-microhaplotype as a novel type of DNA marker for the detection of minor contributor from unbalanced DNA mixtures. Due to their inherent shorter length, higher polymorphism, and sensitivity, DIP-microhaplotypes are promising markers for the examination of the degraded and unbalanced mixtures in forensic stains or clinical chimeras.BACKGROUND Carcinoma cervix is amongst the leading causes of mortality and morbidity in women population worldwide. High-dose-rate intracavitary brachytherapy (HDR-ICBT) post external beam radiation therapy (EBRT) is the standard of care in managing locally advanced stage cervical cancer patients. HDR-ICBT is generally performed under general anaesthesia (GA) in operation theatre (OT), but due to logistic reasons, sometimes, it becomes difficult to accommodate all patients under GA. Since prolonged overall treatment time (OTT) makes the results inferior, taking patients in day care setup under procedural sedation (PS) can be an effective alternative. In this audit, we tried to retrospectively analyse the dosimetric difference, if any, in patients who underwent ICBT at our centre, under either GA in OT or PS in day care. RESULTS Thirty five patients were analysed 16/35 (45.71%) patients underwent HDR-ICBT under GA while 19/35 (54.28%) patients under PS. In both groups, a statistically significant difference was observed between the dose received by 0.1 cc as well as 2 cc of rectum (p  less then  0.05), while the bladder and sigmoid colon had comparable dosages. CONCLUSION Though our dosimetric analysis highlighted better rectal sparing in patients undergoing HDR-ICBT under GA when compared to patients under PS, PS can still be considered an effective alternative, especially in centres dealing with significant patient load. Further studies are required for firm conclusion.A pediatric patient suffering from Marden-Walker syndrome, a rare genetic disease, was referred to the authors' hospital for syncope due to bradycardia. Since this disease is associated with severe joint contractures, a transcatheter leadless pacing system (TPS) was chosen. Despite the small body size and complex anatomy, TPS implantation was feasible, demonstrating that it is a safe alternative in difficult venous access compared to a conventional pacemaker with increased risk of lead complications in these patients.INTRODUCTION Electrophysiology study (EPS) and catheter ablation (abl.), in particular for atrial fibrillation, are increasingly performed in Germany. Therefore, measures and steps to ensure quality assurance are indicated. Most of the procedures are performed by physicians employed by hospitals; however, some are also carried out by attending cardiologists on contract in private practice, applying the so-called Belegarztsystem. The aim of this study was to determine the safety and efficiency of an interventional electrophysiology performed in a German Belegarztsystem. METHODS Based on a prospective registry, we analyzed procedure-related data from 1400 consecutive EPS/abl. performed at our center between 2014 and 2018. One-year follow-up data (arrhythmia recurrences, complications, deaths) were collected for all procedures carried out during the first 2 years. RESULTS In the total study cohort, no periprocedural death occurred, and there was a low cumulative incidence of groin complications (0.9%). The most common procedure (n = 772) was complex ablation for atrial fibrillation/flutter (55%). In this group, the success rate was 98% (acute) and 65% (1 year), and the cumulative rate of complications was 5.0% (transient ischemic attack/stroke 0.1%, pericardial tamponade 0.4%, relevant pericarditis/pericardial effusion 1.1%, groin complication 1.5%, other 1.9%). For the other procedures, rates for success and complications were comparable, and procedure times and x‑ray doses tended to be lower in our analysis as compared to prior reports. CONCLUSION Interventional electrophysiology, carried out by experienced operators and qualified staff, can be performed safely and effectively by attending physicians in a Belegarztsystem.PURPOSE Quantification of myocardial blood flow (MBF) has become central in the clinical application of Rubidium-82 (82Rb) PET myocardial perfusion scans. Current recommendations suggest injections of 1100-1500 MBq of 82Rb in bolus form, which poses a potential risk of PET system saturation on most 3D PET/CT systems currently being used. We aimed to evaluate the frequency and impact of PET system saturation and to test the potential use of a half-dose acquisition protocol. Trastuzumab deruxtecan molecular weight METHODS This study comprised 20 patients who underwent repeated rest scans in a single imaging session, one employing a full-dose (FD), and the other scan a half-dose (HfD) protocol. Datasets were evaluated for saturation based on visual assessments of input functions and sinograms. We compared FD and HfD MBF measurements using Bland-Altman plots, coefficients of variation (CV), and paired t tests. A correction factor permitting serial analyses using FD/HfD imaging protocols was obtained using only the datasets without saturation. RESULTS A dose reduction of 47% was reported for the HfD protocol (FD, 1247 ± 196 MBq; HfD, 662 ± 115 MBq).
