Transglutaminase 2 (TG2) is an enzyme with multiple conformations. In its open conformation, TG2 exhibits transamidase activity linked to fibrosis, arterial remodeling, and endothelial dysfunction, a process enhanced by high glucose in endothelial cells. However, the closed conformation of TG2 contributes to transmembrane signaling and nitric oxide (NO)-dependent vasorelaxation.

For further research in the treatment of this condition, we aimed to establish a porcine model of POI.
Methods: A total of 12 Landrace pigs, weighing 60 kg, were included.
Background: In many practices, the screening for primary aldosteronism relies on a single-blood draw for plasma aldosterone concentration (PAC) and plasma renin activity (PRA) to establish an aldosterone-to-renin ratio (ARR). ARR levels vary between expert centers and repeated assays in the same individual, emphasizing the potential variability of this screening approach. A suppressed PRA to <1 ng/mL per h has been proposed as an alternative test to the ARR.

Cytoreductive surgery (CRS) with hyperthermic intraperitoneal chemotherapy (HIPEC) has improved the 5-year survival for colorectal cancer (CRC) patients with peritoneal metastases (PM). Little is known about recurrence patterns and recurrence rates between synchronous (S) and metachronous (M) PM following CRS+HIPEC. We aimed to describe the recurrence patterns, overall survival (OS) and disease-free survival (DFS) in S-PM and M-PM patients after complete CRS+HIPEC.

Curatively intended treatment includes cytoreductive surgery (CRS) and hyperthermic intraperitoneal chemotherapy (HIPEC) combined with LM resection. A less invasive treatment for LM is ablation.

Second, there are similar data that undertreated patients with PA have a 3-fold higher risk profile than essential hypertensives with the same blood pressure levels. Third, clinicians managing hypertension measure success as sustainable lowering of blood pressure; untreated hypertensive patients with PA are thus in double jeopardy.

Relapse after surgery, postoperative complications, and mortality as well as possible risk factors are not fully understood due to the rareness of the disease.

Methods: Data was collected retrospectively from patient records. Abdominal regions affected by PC were identified using the histological verification of surgically removed tumours found in the electronic pathology report.

Background: Intraabdominal and retroperitoneal sarcomas (IaRS) are malignant connective tissue tumors. Surgical resection is often the only curative treatment. The primary objective was to report the mid-term outcomes following contemporary treatment protocols and identify prognostic factors.
View Article and Find Full Text PDFPrimary aldosteronism, the most common secondary form of hypertension, is thought to be present in ≈5% to 10% of hypertensive adults. However, recent studies indicate that its prevalence may be at least 3-fold higher based on the identification of renin-independent (autonomous) aldosterone production that is not suppressible with dietary sodium loading in a large fraction of adults with primary hypertension. Currently, the screening rate for primary aldosteronism in adults with primary hypertension is <1%.

Certain sites in the peritoneal cavity are prone to contain PM and are, therefore, routinely resected. The aim of this study is to investigate the frequency of disease in CRS specimens routinely resected.

Methods: Retrospectively collected data for 195 consecutive patients who underwent total pelvic exenteration (January 2015-February 2020) at a single tertiary university hospital were analyzed.
Introduction: Cytoreductive surgery with hyperthermic intraperitoneal chemotherapy (CRS + HIPEC) has become the mainstream treatment for peritoneal metastases of colorectal origin. This extensive treatment is known for its increased morbidity rate. In this study, the impact of postoperative complications on survival was evaluated in a high-volume centre.

Since then, screening, diagnosis and treatment have developed, in the process both refining and complicating management. Currently, screening requires 4-6 weeks of lead-up, including major changes in antihypertensive therapy, followed by a blood draw for plasma aldosterone concentration (PAC) and plasma renin activity (PRA) or concentration (PRC).

Treatments targeting the oestrogen signalling pathway are initially highly effective for most patients. However, for the breast cancers that fail to respond, or become resistant, to current endocrine treatments, the long-term outlook is poor.
View Article and Find Full Text PDFBackground: Patients with peritoneal malignancy treated by cytoreductive surgery (CRS) combined with hyperthermic intraperitoneal chemotherapy (HIPEC) are prone to develop postoperative paralytic ileus (POI). POI is associated with significant increase in both morbidity and mortality. CRS and HIPEC commonly result in prolonged POI (PPOI).
