The diets of individual animals within populations can differ, but few studies determine whether this is due to fundamental differences in preferences or capacities to eat specific foods, or to external influences such as dominance hierarchies or spatial variation in food availability. The distinction is important because different drivers of dietary specialisation are likely to have different impacts on the way in which animal populations respond to, for example, habitat modification. https://www.selleckchem.com/products/proxalutamide-gt0918.html We used a captive feeding study to investigate the mechanisms driving individual dietary specialisation in a population of wild koalas (Phascolarctos cinereus) in which individuals predominantly ate either Eucalyptus viminalis or Eucalyptus obliqua foliage. All six koalas that primarily ate E. viminalis in the wild avoided eating E. obliqua for more than 1 month in captivity. In contrast, all seven koalas that primarily ate E. obliqua could be maintained exclusively on this species in captivity, although they ate less from individual trees with higher foliar concentrations of unsubstituted B-ring flavanones (UBFs). Our results show that fundamental differences between individual animals allow some to exploit food resources that are less suitable for others. This could reduce competition for food, increase habitat carrying capacity, and is also likely to buffer the population against extinction in the face of habitat modification. The occurrence of fundamental individual specialisation within animal populations could also affect the perceived conservation value of different habitats, translocation or reintroduction success, and population dynamics. It should therefore be further investigated in other mammalian herbivore species. To explore the usability and diagnostic accuracy for prostate cancer of three multiparametric magnetic resonance imaging (mpMRI)/transrectal ultrasound (TRUS)-guided fusion biopsy systems operated by the same urologists. We performed a prospective, observational study including patients that underwent prostate biopsy due to a visible lesion in mpMRI (PI-RADS ≥ 3). We consecutively assessed two platforms with a rigid image registration (BioJet, D&K Technologies and UroNav, Invivo Corporation) and one with an elastic registration (Trinity, KOELIS). Four urologists evaluated each fusion system in terms of usability based on the System Usability Scale and diagnostic accuracy based on the detection of prostate cancer. We enrolled 60 consecutive patients that received mpMRI/TRUS-guided prostate biopsy with the BioJet (n = 20), UroNav (n = 20) or Trinity (n = 20) fusion system. Comparing the rigid with the elastic registration systems, the rigid registration systems were more user-friendly compared to the elastic registration systems (p = 0.012). Similarly, the prostate biopsy with the rigid registration systems had a shorter duration compared to the elastic registration system (p < 0.001). Overall, 40 cases of prostate cancer were detected. Of them, both the BioJet and UroNav fusion systems detected 13 prostate cancer cases, while the Trinity detected 14. No significant differences were demonstrated among the three fusion biopsy systems in terms of highest ISUP Grade Group (p > 0.99). Rigid fusion biopsy systems are easier to use and provide shorter operative time compared to elastic systems, while both types of platforms display similar detection rates for prostate cancer. Still, further high-quality, long-term results are mandatory.

This systematic review aims at reporting the incidence, predictive factors, and the oncological outcomes of incidental prostate cancer (IPCa) in men who underwent endoscopic enucleation of prostate (EEP). A literature search was performed using the following Medical Subject Heading (MeSH) terms and keywords "Prostatic Neoplasms", "Prostate Cancer", "Transurethral Resection of Prostate", "Prostate resection", "Prostate enucleation". Meta-analysis was performed if there were two or more studies reporting the same outcome under the same definition. In case of insufficient data, results were presented in a narrative manner. Sixty-one studies were included in qualitative synthesis and 55 were included in meta-analysis. The pooled IPCa rate was 0.08 (95% CI 0.073-0.088). Increasing age, higher preoperative serum prostate-specific antigen (PSA) level, higher preoperative PSA density (PSAD), smaller prostate volume, higher postoperative PSA velocity and lower enucleated prostate weight, were reported to have significant correlation with IPCa. In BPH patients, the mean pre-operative and post-operative PSA levels were 5.58 ± 1.48ng/dL and 1.06 ± 0.27ng/dL, respectively. In patients with IPCa, the mean pre-operative and post-operative PSA levels were 7.72 ± 2.90ng/dL and 2.77 ± 1.66ng/dL, respectively. The mean percentage PSA reduction was 82.0% ± 1.8% for BPH patients and 68.2% ± 12.1% for IPCa patients. IPCa was most commonly managed byactive surveillance (68.7%). The pooled incidence of IPCa after EEP was 8%. An absolute post-operative PSA level of < 2.0 and a percentage PSA reduction of > 70% should be expected in BPH patients after EEP. 70% should be expected in BPH patients after EEP. Prolonged postoperative ileus (PPOI) is common after bowel resections, especially in Crohn's disease (CD). The pathophysiology of PPOI is not fully understood. PPOI could affect only the upper or lower gastrointestinal (GI) tract. The aim of this study was to assess risk factors for diverse types of PPOI, particularly to differentiate PPOI of upper and lower GI tract. A retrospective analysis of 163 patients with CD undergoing ileocecal resection from 2015 to 2020 in a single center was performed. PPOI of the upper GI tract was predefined as the presence of vomiting or use of nasogastric tube longer than the third postoperative day. Lower PPOI was predefined as the absence of defecation for more than three days. Independent risk factors were identified by multivariable logistic regression analysis. Overall incidence of PPOI was 42.7%. PPOI of the upper GI tract was observed in 30.7% and lower PPOI in 20.9% of patients. Independent risk factors for upper PPOI included older age, surgery by a resident surgeon, hand-sewn anastomosis, prolonged opioid analgesia, and reoperation, while for lower PPOI included BMI ≤ 25kg/m , preoperative anemia, and absence of ileostomy.
