Our results also align with previous studies in another chameleon species, thus supporting the key role of brightness changes in chameleon communication, at least in a competitive context. Interestingly, although our species did exhibit UV coloration, neither this coloration nor its changes seem to be involved in intrasexual agonistic interactions among males, possibly because those signals may be used for other purposes like attracting mates, repelling predators, or deception.Immunotherapy has revolutionized the systemic treatment of solid tumors, including advanced urothelial carcinoma (aUC), providing durable responses with a favorable safety profile. Multiple immune checkpoint inhibitor agents have been approved in monotherapy in second-line setting, and for a selected group of chemo-naïve cisplatin-ineligible patients with high PD-L1 expression. Despite the incorporation of immunotherapy to the systemic treatment landscape of aUC, platinum-based chemotherapy remains the standard of care in frontline setting for vast majority of patients. Urothelial carcinoma is a chemosensitive disease with response rates of up to 50% to frontline chemotherapy. However, the response to chemotherapy is short lasting with vast majority of patients experiencing disease progression and death within months. In this context, maintenance therapy constitutes an attractive therapeutic strategy to maximize the time to treatment failure. Different cytotoxic and targeted agents have been investigated as maintenance therapy for aUC but have not shown an impact on survival. Avelumab has become the first and only drug to improve overall survival as maintenance therapy after frontline platinum-based therapy in aUC patients and the first drug to be approved in this setting. This article will review the rational for maintenance therapy, the different drugs investigated as maintenance therapy for aUC, and the impact of avelumab maintenance therapy as a new standard of care in the management of aUC.
Area-based socioeconomic deprivation has been established as an important indicator of health and a potential predictor of survival. In this study, we aimed to measure the effect of socioeconomic inequality on endometrial cancer survival.
Population-based data on patients diagnosed with endometrial cancer between 2004 and 2014 were obtained from the German Centre for Cancer Registry Data. Socioeconomic inequality was defined by the German Index of Socioeconomic Deprivation. We investigated the association of deprivation and overall survival throughKaplan-Meier curves and Cox proportional regression models.
A total of 21,602 women, with a mean age of 67.8years, were included in our analysis. The observed 5-year overall survival time for endometrial cancer patients living in the most affluent districts (first quintile) was 78.6%. The overall survival rate decreased as the level of deprivation increased (77.2%,73.9%,76.1%, 74.7%, for patients in the second, third, fourth, and fifth quintile (most deprived patients), respectively).Cox regression models showed stage I patients living in the most deprived districts to have a higher hazard of overall mortality when compared to the cases living in the most affluent districts [Hazard ratio 1.20; 95% Confidence interval (0.99-1.47)] after adjusting for age, tumor characteristics, and treatment.
Our results indicate differences in endometrial cancer survival according to socioeconomic deprivation among stage I patients. Considering data limitations, future studies with access to individual-level patient information should be conducted to examine the underlying causes for the observed disparity in cancer survival.

Studies assessing the effect of implementing good practice management guidelines (GPMG) in carotid revascularization within the same hospital are scarce. Thus, we aimed to evaluate the impact of GPMG implementation on the clinical outcomes of carotid revascularization procedures within a quaternary hospital.
We retrospectively studied 177 patients with atherosclerotic carotid disease who underwent revascularization (carotid endarterectomy and carotid artery stenting) at a quaternary hospital between January 2012 and December 2019. The patients were divided into two groups the pre-guideline group with 73 patients and the post-guideline group with 104 patients who underwent the procedures before and after the implementation of GPMG, respectively.
Twelve (16.4%) and 3 (2.9%) patients had neurological complications in the pre- and post-guideline groups, respectively (p = 0.001); most complications were cases of ischemic stroke. There were fewer complications in men than in women (OR = 0.22; 95% CI 0.06-0.77). A significant decrease in neurological complications was observed in the carotid artery stenting group (pre-guideline 25.7% vs post-guideline 13.2%; p = 0.004). Logistic regression analysis of the predisposing factors for neurological complications in carotid endarterectomy and carotid artery stenting demonstrated that the implementation of GPMG was a determining factor for the improved results (odds ratio = 0.11, 95% CI 0.02-0.59).
Implementing GPMG for carotid revascularization resulted in better clinical results, with decreased neurological complications in patients that underwent angioplasty and endarterectomy.

Since the distribution of the data was commonly not Gaussian, they were transformed into their natural logarithm for deriving background concentrations and precautionary values. Background concentrations were defined as antilog of the median. Precautionary concentration values for soil protection were defined as antilog of 90th percentile of the ln-transformed data. Background concentrations in forest soils were larger compared to those in soils under other land use types. The largest background concentrations for Cd, Cr, Ni, Cu, Co, and Zn were found in forest soils formed on magmatic rocks, while largest concentrations of Pb and Hg were found in soils formed on flysch and molasse. The background values and precautionary concentration values (in brackets) (mg kg-1) for agricultural soils across flysch/molasses and quaternary deposits were as follows Cd 0.24 (0.82), Cr 131.63 (527.42), Cu 41.26 (72.75), Ni 287.15 (632.70), Pb 19.11 (284.86), Zn 81.80 (113.90). The largest background values for Cd and Zn were found in Phaeozems, for Cr, Pb, and Co in Luvisols and Cambisols, and for Cu, Hg, and Ni in Fluvisols. The proposed background concentrations and precautionary values complete the picture of metal contents in European soils, can be used as reference concentrations for the Albanian environmental legislation, and allow the identification of potential contamination hot spots.
To evaluate the effect of a collagen sponge containing simvastatin on socket healing in terms of bone microarchitecture through tomographic analysis, pain, and swelling after impacted third molar extraction.
In this single-blind, split-mouth, randomized clinical trial, 29 patients undergoing impacted third molar extraction were allocated into two groups (i) test group, a collagen sponge containing simvastatin was inserted within the sockets; and (ii) control group, in which sockets retained the clot. Bone volume (BV), bone volume fraction (BV/TV), trabecular thickness (Tb.Th), trabecular spacing (Tb.Sp), and gray scale were evaluated using cone beam computed tomography (CBCT) acquired immediately postoperative and 3months after surgery. Pain, swelling, and wound healing were evaluated using the 10-point visual analogue scale, three extra-oral reference measurements, and the Landry index.
In total, 22 participants remained in the study; no loss-to-follow-up was related to the intervention. BV and BV/TV were significantly higher at 3months postoperatively in the test group compared with the control group and were correlated with greater bone trabeculation. Pain, edema, and the Landry index revealed a greater inflammatory response in the test group during early repair. Simvastatin contributed to bone healing, with no adverse effects or postoperative complications.
The absorbable collagen sponge containing simvastatin improved BV, BV/TV, and trabecular bone, indicating the potential of this drug to induce the formation of autogenous bone.
Intraosseous statins represent a promising, low-cost, and easy-to-use alternative for alveolar ridge preservation and bone regeneration.

The multidimensional role of hamstring muscle group strength in athletic performance and injury prevention is well documented, and nordic hamstring exercise (NHE) is a popular method for the development of hamstring strength. Our aim was to examine the EMG characteristics of the eccentric NHE as well as the effects of long-term eccentric NHE training on muscle strength and vertical jump performance in 10- to 11-year-old female handball players.
Players from the same handball team were randomly assigned to an eccentric NHE training (13 players) or a control group (10 players). Both groups continued their regular handball training routine, but the NHE group performed additional eccentric NHE exercises once or twice a week, with progressively increasing volume, over 20 weeks. To test training effects, countermovement jump (CMJ) height, eccentric hamstring impulse, peak torque, and angle of peak torque were evaluated before, during and after the training period. In the pre-exercise test, EMG activity of the medial and lateral hamstring muscle was also assessed during NHE.
Hamstring activities ranged between 98 and 129%. Lateral hamstring activity was greater than medial only in the right leg during NHE. Eccentric hamstring impulse improved in both legs at 10 weeks in both groups. Then, at 20weeks, it remained unchanged in the NHE but decreased in controls. A similar adaptation was seen in eccentric hamstring torque, without change in the optimum knee angle. learn more CMJ height improved only in the NHE.
It is concluded that NHE activates the hamstring musculature effectively, and a favourable mechanical adaptation to long-term NHE exercise in girls can be triggered as early as 11years of age.

Many studies have analyzed the distribution of blowflies based on pig experiments and baited trapping; however, data from real case scenarios are rarely used. In this article, the distribution of blowflies found during investigations of 160 real cases during 1993-2007 in Switzerland is evaluated based on habitat, altitude, and season. Ten species of blowflies were present in 145 out of the 160 cases. The most common species was Calliphora vicina, which occurs throughout the year and was present in 69 % of all cases. Lucilia sericata, Calliphora vomitoria, and L. caesar were identified among the rest of the flies as species of great forensic importance mainly due to their distributional patterns. After a comparison with a similar dataset from Frankfurt, Germany, some surprising differences were determined and discussed. The biggest discrepancies between our dataset and the German dataset were in the occurrences of L.
