Finally, miR-182-5p mimic inhibited NF-κB signaling pathway activation in AR mice. However, all effects of miR-182-5p mimic on AR mice were reversed by TLR4-plasmid. In conclusion, miR-182-5p/TLR4 axis may represent a novel therapeutic target for AR.

Mitochondrial dysregulation is a key event in HIV-1 infection. Recent studies have suggested that age-related neurodegenerative disorders are associated with increased mitochondrial DNA (mtDNA) damage. As accelerated ageing was found in HIV-1 patients, we hypothesized that HIV-1 infection or HIV-1 proteins can lead to mtDNA damage. Unrepaired mtDNA impairs mitochondrial function, which can lead to oxidative stress and cell death. Investigations of mechanisms of mtDNA damage are limited by the lack of available human models.

We compared mtDNA or nDNA (nuclear DNA) damage in human cortical neurons and PBMC cells. Primary neuronal cultures were incubated with conditioned media from HIV-1 infected PBMC, or HIV-1 viral proteins Tat or Vpr. Total genomic DNA (nuclear and mtDNA) was isolated using the QIAamp Kit. Nuclear and mtDNA were amplified using the long q-PCR/Gene Amp XL Kit. Real-Time RT-PCR using mitochondrial energy metabolism array was performed to assess mitochondrial energy metabolism markers. Supery metabolism, suggesting involvement of Tat in mitochondrial bioenergetics in human neurons. Finally, our hypothesis was confirmed by qWestern analysis of mitochondrial and apoptotic proteins demonstrating the accumulation of apoptotic Bax and Bad proteins in mitochondrial fraction of Tat-treated neuronal cells, suggesting toxic effects of Tat on mitochondrial survival.

We showed an increase of mtDNA damage in primary neurons, treated with HIV-1 proteins and in PBMC, infected with HIV-1. Increased mtDNA damage can lead to neurodegeneration, and cause neuronal apoptosis. Our system presents a suitable model to study mtDNA changes during HIV-1 infection.

The National Mesothelioma Audit 2020 showed Northumbria to have low rates of histopathological confirmation, treatment and one-year survival rates for malignant pleural mesothelioma (MPM). We hypothesized that an internal analysis over a 10-year period provides valuable insights into presentation, diagnosis, treatment and outcomes.

A single-centre retrospective case series of all confirmed MPM patients between 1 January 2009 and 31 December 2019 was performed. Demographics, clinical, radiological and histopathological characteristics and outcomes were collected. Statistical analysis was performed using SPSS V26.0.

A total of 247 patients had MPM. About 86% were male, mean age 75.7 years. Dyspnoea (77.4%) and chest pain (38.5%) were commonest symptoms. 64.9 and 71.4% had pleural thickening and effusion, respectively. Aprotinin About 86.8% had at least one attempt to obtain a tissue biopsy, but histopathological confirmation in only 108 (43.7%). About 66.3% with PS 0 and 1 (62.7% of total cohort) had at least one anti-cancer therapy. Death within 12months wasassociated with disease progression within 6months (p≤0.001). Chemotherapy (p≤0.001) and epithelioid histological subtype (p=0.01) were protective.

This study confirms known epidemiology ofMPM, demonstrates variability in practices and highlights how some NMA recommendations are not met. This provides the incentive for a regional mesothelioma multi-disciplinary meeting.

Extraskeletal Ewing's sarcoma is a rarity, with a renal primary in an adult, being even rarer. There is no consensus on the optimal imaging modality, as well as best therapeutic option, making them an enigma for clinicians.

We report the case of a 34-year-old lady, a known case of invasive lobular carcinoma of the left breast (ER,PR positive, Her2neu negative), having completed treatment in 2017, wherein, on an ultrasound evaluation for left flank pain, was incidentally found to have a left renal mass. A CT scan corroborated with the ultrasound, with an additional Level 1, left renal vein thrombus. She underwent an open left radical nephrectomy with renal vein thrombectomy. Histopathology of the resected tumor revealed features of Ewing's sarcoma of the kidney, confirmed by Fluorescent In Situ Hybridisation (FISH) and Immunohistochemistry (IHC).

Primary renal Ewing's sarcoma in an adult is a rare occurrence, with no characteristic imaging features, and no universally accepted guideline based management protocols. Akin with standard Ewings sarcoma treatment strategies, a margin negative- radical nephrectomy with adjuvant chemotherapy, seems the most apt treatment strategy.

Direct electrical stimulation of the peroneal nerve, using the implantable ActiGait® system, enables a therapy of the centrally caused drop foot, to improve the gait of the patients. In this paper, we present long-term results at 36-month follow-up post implantation.

A total of 33 patients, 27 stroke and six multiple sclerosis (MS) patients, suffering from spastic drop foot were implanted in our center and assessed in terms of gait endurance, speed, risk of fall, and life quality at baseline and 36 months following implantation.

The six min gait endurance test increased significantly from 202±41m without walking aids to 380±30m (p=0.038), while using the implant. Moreover, the time in the gait speed measured over 20m decreased from 31.8±10.2s without to 18.5±4.6s by using the ActiGait® system (p=0.039). Similarly, gait steadiness, measured by the Timed Up and Go (TUG) test improved by 36.6%, with patients demonstrating a reduced time from 18.6±5.5 to 11.2±3.8s (p=0.041) upon implant activation. Most importantly, 31 of 33 patients reported remarkable improvements of their quality of life following direct electrical nerve stimulation.

Our findings confirm previously published efficacy data at 12 months after implantation and underline the long-lasting effect of the ActiGait® system.

As an essential part of the health care system, therequirements for specialist training are subject to a continuous process of change. The aim of the present study was to evaluate the current specialist training situation of all departments in a tertiary care hospital in Germany. Differences between assistant and chief physicians should be pointed out.

The analysis of the current training situation was carried out on the basis of an individually created questionnaire. The questionnaire content included career goal and specialism. The characteristic values initial training (IT), training structure (TS) and training content were measured on a numeric scale from 1 to 5. In addition, an overall assessment of the trainers' competences was performed. The questionnaire was sent to 208 assistant physicians (AP) and 34 chief physicians (CP).

Totally 92 APs (44.2%) and 22 CPs (64.7%) participated. Senior physician was the most common career goal (34.1%), followed by the branch (28.6%). The importance of the topicy in patient care.

Our data underline the importance of specialist training subjects. These are partly perceived very differently by APs and CPs. Innovative concepts for the induction phase, well-structured training curricula, providing management skills, the overall use of skills labs and digital documentation might support the satisfaction and the outcome of specialist training. This could also improve quality in patient care.

The postoperative pancreatic fistula (POPF) is a major complication after pancreatic head resection whereby the technique of the anastomosis is a very influencing factor. The literature describes a possible protective role of the Blumgart anastomosis.

Patients after pancreatic head resection with reconstruction through the modified Blumgart anastomosis (a 2 row pancreatic anastomosis through mattress sutures of the parenchyma and duct to mucosa pancreaticojejunostomy, Blumgart-group) were compared with patients after pancreatic head resection and reconstruction through the conventional pancreatojejunostomy (single suture technique of capsule and parenchyma to seromuscularis, PJ-group). The Data were collected retrospectively. Depending on the propensity score matching in a ratio of 12 comparison groups were set up. Blumgart-group (n=29) and PJ-group (n=56). The primary end point was the rate of POPF. Secondary goals were duration of operation, length of hospital stay, length of stay on intermediate care units and hospital mortality.

The rate of POPF (biochemical leak, POPF "grade B" and POPF "grade C") was less in the Blumgart-group, but without statistical relevance (p=0.23). Significantly less was the rate of POPF "grade C" in the Blumgart-group (p=0.03). Regarding the duration of hospital stay, length of stay on intermediate care units and hospital mortality, there was no relevant statistical difference between the groups (p=0.1; p=0.4; p=0.7). The duration of the operation was significantly less in the Blumgart-group (p=0.001).

The modified Blumgart anastomosis technique may have the potential to decrease major postoperative pancreatic fistula.

We report the cases of a 35-year-old man with abdominal discomfort and a 50-year-old asymptomatic woman with large retroperitoneal masses. Both underwent multivisceral surgery to exclude an adrenal carcinoma, and the pathologic diagnosis showed schwannomas in both cases. Despite morphological imaging, it was not possible to get a clear diagnosis preoperatively.

We describe the first application of intrauterine negative-pressure therapy (IU-NPT) for an early rupture of a uterine suture after a third caesarean section with consecutive peritonitis and sepsis. Because all four quadrants were affected by peritonitis, a laparotomy was performed on the 15th day after caesarean section. Abdominal negative-pressure wound therapy (A-NPWT) of the open abdomen was initiated. During the planned relaparotomy, a suture defect of the anterior uterine wall was identified and sutured. In the second relaparotomy, the suture appeared once more insufficient.

For subsequent IU-NPT, we used an open-pore film drainage (OFD) consisting of a drainage tube wrapped in the double-layered film. The OFD was inserted into the uterine cavity via the uterine defect and IU-NPT was established together with A-NPT. With the next relaparotomy, local inflammation and peritonitis had been resolved completely. IU-NPT was continued transvaginally, the uterine defect was sutured, and the abdomen was closed.
