Le syndrome hépato-rénal: revue Le syndrome hépato-rénal (SHR) est défini comme une insuffisance rénale fonctionnelle chez les patients atteints d'une maladie hépatique présentant des reins morphologiquement intacts, où les mécanismes de régulation ont minimisé la filtration glomérulaire et maximisé la résorption tubulaire et la concentration urinaire. Le syndrome survient presque exclusivement chez les patients atteints d'ascite. Le type 1 du SHR se développe à la suite d'une réduction sévère du volume circulant efficace en raison d'une vasodilatation artérielle splanchnique extrême et une réduction du débit cardiaque. Le type 2 du SHR est caractérisé par une insuffisance rénale stable ou lentement progressive, de sorte que sa principale conséquence clinique n'est pas une insuffisance rénale aiguë, mais une ascite réfractaire, et son impact sur le pronostic est moins négatif. La transplantation hépatique est la méthode thérapeutique

Evidence regarding the relation between SARS-CoV-2 mortality and the underlying medical condition is scarce. We conducted an observational, retrospective study based on Romanian official data about location, age, gender and comorbidities for COVID-19 fatalities. Our findings indicate that males, hypertension, diabetes, obesity and chronic kidney disease were most frequent in the COVID-19 fatalities, that the burden of disease was low, and that the prognosis for 1-year survival probability was high in the sample. Evidence shows that age-dependent pairs of comorbidities could be a negative prognosis factor for the severity of disease for the SARS-CoV 2 infection.

This paper’s primary aim is to outline relevant aspects regarding the biocompatibility of PMMA (poly(methyl methacrylate))-based materials used for obtaining interim prosthetic restorations, such as the interaction with oral epithelial cells, fibroblasts or dental pulp cells, the salivary oxidative stress response, and monomer release. Additionally, the oral environment’s biochemical response to modern interim dental materials containing PMMA (obtained via subtractive or additive methods) is highlighted in this review. The studies included in this paper confirmed that PMMA-based materials interact in a complex way with the oral environment, and therefore, different concerns about the possible adverse oral effects caused by these materials were analyzed. Adjacent to these aspects, the present work describes several advantages of PMMA-based dental materials. Moreover, the paper underlines that recent scientific studies ascertain that the modern techniques used for obtaining interim prosthetic materials, milled PMMA, and 3D (three-dimensional) printed resins, have distinctive advantages compared to the conventional ones. However, considering the limited number of studies focusing on the chemical composition and biocompatibility of these modern interim prosthetic materials, especially for the 3D printed ones, more aspects regarding their interaction with the oral environment need to be further investigated.

Periodontitis represents a complex inflammatory disease that compromises the integrity of the tooth-supporting tissue through the interaction of specific periodontal pathogens and the host’s immune system. Experimental data help to outline the idea that the molecular way towards periodontitis initiation and progression presents four key steps: bacterial infection, inflammation, oxidative stress, and autophagy. The aim of this review is to outline the autophagy involvement in the pathogenesis and evolution of periodontitis from at least three points of view: periodontal pathogen invasion control, innate immune signaling pathways regulation and apoptosis inhibition in periodontal cells. The exact roles played by reactive oxygen species (ROS) inside the molecular mechanisms for autophagy initiation in periodontitis still require further investigation. However, clarifying the role and the mechanism of redox regulation of autophagy in the periodontitis context may be particularly beneficial for the elaboration of new therapeutic strategies.

Endometriosis, one of the most common gynecologic pathologies, is defined as an inflammatory, estrogen-dependent disease characterized by the growth of endometrial stroma and glands outside the uterine cavity. It is a multifactorial disease, conditioned by genetic and immune factors and triggered by hormonal and environmental factors. Estrogen receptors (ER) and progesterone receptors (PR) expression is significantly modified in endometriotic tissue, compared to normal endometrium. We performed a prospective study that included 16 patients with endometriosis: 9 patients that underwent progesterone treatment with 0.075 mg desogestrel, daily for 24 weeks prior to the surgical procedure, and 7 patients that did not follow any kind of treatment. The purpose of the study was to evaluate the changes that occurred in the expression of ER, PR, B-cell lymphoma 2 (Bcl-2) and Ki-67 from the endometriotic tissue. Oral 0.075 mg desogestrel administration proved its benefits in the management of endometriomas.
