Relapse in drug use constitutes a research topic on addiction that is relevant for understanding both the addictive process and its clinical implications. The objective of this study was to explore if it is possible to identify patient profiles according to their performance on cognitive tasks whilst examining the relationship between such profiles and relapse.

The sample consisted of 222 patients with dependence on cocaine and / or alcohol, of which 86 % were men. Cognitive domains related to salience, decision- making, and emotional processing were measured.

Latent class analysis revealed three patient profiles that differ in terms of performance on cognitive tasks. Two of these profiles are clearly differentiated in terms of their execution of the impulsive decision-making task. The third patient profile, unlike the latter two, is composed of patients with severe alterations in the three domains evaluated. Analysis revealed that patients in Profile 3 are those with the highest rates of relapse in cocaine (Profile 1 = 40.3 %; Profile 2 = 35.6 %; Profile 3 = 69.2 %; Chi2 = 9.169; p < .05) and cocaine and alcohol use (Profile 1 = 55.1 %; Profile 2 = 54.1 %; Profile 3 = 80 %; Chi2 = 6.698; p < .05).

The results support the postulates of the I-RISA model. From a clinical perspective, these findings highlight the need for a comprehensive evaluation of the cognitive domains involved in addiction.

Duplex system is the most common upper urinary tract anomaly in childhood. The purpose of our study was to investigate the incidence, characteristics, and progression of lower pole hydronephrosis in children with duplex system who underwent transurethral incision (TUI) of upper pole ureterocele.

Among children who underwent transurethral incision of ureteroceles between 2006 and 2018, 69 renal units with duplex systems were included after exclusion of preoperative lower pole vesicoureteral reflux and follow up loss. We retrospectively analyzed the postoperative progression of lower pole hydronephrosis and compared patient characteristics between two groups according to the presence of lower pole hydronephrosis.

The median age at operation and follow-up duration were 3.0 months (range 0-242 months) and 59 months, respectively. The median size of ureteroceles preoperatively was 14.5mm. Thirty-five renal units (50.7%) demonstrated preoperative lower pole hydronephrosis of any grade (grade I in 13 [37.1%], the diameter of upper pole ureter. Most of renal units demonstrated significant improvement of lower pole hydronephrosis after transurethral incision of ureterocele. Given that differential renal function may be decreased even after improvement of hydronephrosis with TUI, a more careful monitoring on renal function is required in patients with hydronephrosis on lower pole.
Lower pole hydronephrosis was found in a considerable number of renal units (50.7%), and the occurrence was related with the diameter of upper pole ureter. Most of renal units demonstrated significant improvement of lower pole hydronephrosis after transurethral incision of ureterocele. Given that differential renal function may be decreased even after improvement of hydronephrosis with TUI, a more careful monitoring on renal function is required in patients with hydronephrosis on lower pole.Autophagy is required for normal skin homeostasis and its disordered regulation is implicated in a range of cutaneous diseases. Several well-characterized biomarkers of autophagy are used experimentally to quantify autophagic activity or clinically to correlate autophagy with disease progression. This article discusses the advantages and limitations of different approaches for measuring autophagy as well as the techniques for modulating autophagy. These include analysis of endogenous LC3, a central autophagy regulatory protein, and measurement of LC3 flux using a dual-fluorescent reporter, which provides a quantitative readout of autophagy in cell culture systems in vitro and animal models in vivo. Degradation of SQSTM1/p62 during autophagy is proposed as an alternative biomarker allowing the analysis of autophagy both experimentally and clinically. However, the complex regulation of individual autophagy proteins and their involvement in multiple pathways means that several proteins must be analyzed together, preferably over a time course to accurately interpret changes in autophagic activity. Genetic modification of autophagy proteins can be used to better understand basic autophagic mechanisms contributing to health and disease, whereas small molecule inhibitors of autophagy regulatory proteins, lysosomal inhibitors, or activators of cytotoxic autophagy have been explored as potential treatments for skin disorders where autophagy is defective.The results in the article by Zhou et al. (2020) demonstrate that the antidiabetic drug phenformin inhibits skin tumor growth and promotes keratinocyte differentiation, and an underlying mechanism is also defined. Navitoclax concentration In this commentary, additional potential mechanisms through which phenformin may exert its antitumorigenic effect are described. Thus, the proposed repurposing of phenformin to treat skin cancer has merit.
Low-dose radiation exposure to Canadians is exponentially increasing due to the influx of diagnostic imaging and medical procedures that utilize radiation. Despite the use of medical radiation since 1896, the standardized acceptable dose for the Canadian public is still debated. The current annual dose limit for the public is set at 1 millisievert (mSv). This set dose limit intrinsically restricts the use of medical radiation for diagnosis due to concerns of public health.

This systematic review is in the form of a retrospective meta-analysis of previous experimental studies and observational reviews of low-dose radiation health effects. A database search using PubMed and Medscape identified 1,296 articles using the terms "low-dose radiation", "radiation hormesis", "radiation safety", "dose exposure", and "medical radiation". Full text articles were excluded for the following reasons radiation dose level not <100mSv, results of radiation effects not included, or no inclusion of biologic effects on living tissue.
