How autistic women are aware of their body and take care of their health? Focus on menstruation cycles and gynecological care.

Objective: The combination of femininity and inequality is an increasingly studied in the field of social medicine, even more if the girls or women in question experience conditions of disability or neurodivergence. The onset of menstruation, menarche, constitutes a significant and transformative event in women's lives comprising a true and proper watershed in mental and reproductive health and sexual welfare. The onset of menstruation has a profound effect not just for girls but, in the case of disabled girls, for the whole family. In this scoping review, we have researched the literature in studies which consider the issue of menstruation and autism. The works in scientific literature have been selected which, in the last 5 years, investigated the issue of menstrua-tion for autistic girls and/or women. Results: Selected studies, although few in number, have all equally evidenced the total lack of in-depth understanding of this theme, notwithstanding the fact that females, girls and women with autism would benefit from specialized services if these existed. Families, girls and women involved, moreover, although not experiencing menstruation per se in a negative light, note a deterioration in their condition particularly in respect of sensorial perception and the intensification of anxious depressive instances. This work highlights the need to deepen the aspects concerning the period in autistic girls/women, up to now the question appears to have been little studied, investigated in an uneven way. We propose a social medical program to improve sexual-affective knowledge and body awareness in autistic people.

Investigation of microglial diversity in a LRRK2 G2019S mouse model of Parkinson's disease.

Microglia contribute to the outcomes of various pathological conditions including Parkinson's disease (PD). Microglia are heterogenous, with a variety of states recently identified in aging and neurodegenerative disease models. Here, we delved into the diversity of microglia in a preclinical PD model featuring the G2019S mutation in LRRK2, a known pathological mutation associated with PD. Specifically, we investigated the 'dark microglia' (DM) and the 'disease-associated microglia' (DAM) which present a selective enrichment of CLEC7A expression. In the dorsal striatum - a region affected by PD pathology - extensive ultrastructural features of cellular stress as well as reduced direct cellular contacts, were observed for microglia from old LRRK2 G2019S mice versus controls. In addition, DM were more prevalent while CLEC7A-positive microglia had extensive phagocytic ultrastructural characteristics in the LRRK2 G2019S mice. Furthermore, our findings revealed a higher proportion of DM in LRRK2 G2019S mice, and an increased number of CLEC7A-positive cells with age, exacerbated by the pathological mutation. These CLEC7A-positive cells exhibited a selective enrichment of ameboid morphology and tended to cluster in the affected animals. In summary, we provide novel insights into the occurrence and features of recently defined microglial states, CLEC7A-positive cells and DM, in the context of LRRK2 G2019S PD pathology.

Glutamate-induced excitotoxicity in Parkinson's disease: The role of glial cells.

Glutamate is the major excitatory neurotransmitter in the central nervous system. Glutamate transmission efficiency depends on the correct functionality and expression of a plethora of receptors and transporters, located both on neurons and glial cells. Of note, glutamate reuptake by dedicated transporters prevents its accumulation at the synapse as well as non-physiological spillover. Indeed, extracellular glutamate increase causes aberrant synaptic signaling leading to neuronal excitotoxicity and death. Moreover, extrasynaptic glutamate diffusion is strongly associated with glia reaction and neuroinflammation. Glutamate-induced excitotoxicity is mainly linked to an impaired ability of glial cells to reuptake and respond to glutamate, then this is considered a common hallmark in many neurodegenerative diseases, including Parkinson's disease (PD). In this review, we discuss the function of astrocytes and microglia in glutamate homeostasis, focusing on how glial dysfunction causes glutamate-induced excitotoxicity leading to neurodegeneration in PD.

Essential Role of the cVRG in the Generation of Both the Expiratory and Inspiratory Components of the Cough Reflex.

As stated by Korpás and Tomori (1979), cough is the most important airway protective reflex which provides airway defensive responses to nociceptive stimuli. They recognized that active expiratory efforts, due to the activation of caudal ventral respiratory group (cVRG) expiratory premotoneurons, are the prominent component of coughs. Here, we discuss data suggesting that neurons located in the cVRG have an essential role in the generation of both the inspiratory and expiratory components of the cough reflex. Some lines of evidence indicate that cVRG expiratory neurons, when strongly activated, may subserve the alternation of inspiratory and expiratory cough bursts, possibly owing to the presence of axon collaterals. Of note, experimental findings such as blockade or impairment of glutamatergic transmission to the cVRG neurons lead to the view that neurons located in the cVRG are crucial for the production of the complete cough motor pattern. The involvement of bulbospinal expiratory neurons seems unlikely since their activation affects differentially expiratory and inspiratory muscles, while their blockade does not affect baseline inspiratory activity. Thus, other types of cVRG neurons with their medullary projections should have a role and possibly contribute to the fine tuning of the intensity of inspiratory and expiratory efforts.

Impact of dose-dense immunochemotherapy on prognosis of germinal center and non germinal center origin of diffuse large B cell lymphoma.

Diffuse large B cell lymphoma (DLBCL) is the most common type of non-Hodgkin's lymphoma. Gene-expression profiling in DLCBL has brought insight into the biological heterogeneity of the disease. Two major subgroups have been identified: germinal center B (GCB) cell and non-germinal center (non-GCB). The aim of this study was to define retrospectively by immunohistochemistry the bcell origin of 69 patients treated with R-CHOP14 and to evaluate if dose-dense therapy could improve their clinical outcome. According to immunohistochemistry analysis 28 patients were derived from germinal center and 41 from non-germinal center. After a median period of observation of 46 months (range 3-101 months) the overall survival (OS) was 75% and progression-free survival (PFS) was 53% and no differences were observed according to cell origin. In conclusion, we can point out that intensification could enhance the efficacy of the R-CHOP regimen and improve overall survival in patients with non germinal lymphoma.

Effects of nicardipine on intimal-medial thickness and arterial distensibility in hypertensive patients. Preliminary results after 6 months.

BACKGROUND: The aim of this study was to evaluate the effects of nicardipine, at the dosage of 80 mg/day in two administrations, on blood pressure, intimal-media thickness of the common carotid artery and on arterial distensibility after 6 months of therapy. The study population consisted of 23 patients, 13 male and 10 female, mean age 61.7 +/- 10.1 years, with systolic blood pressure 170.4 +/- 14.5 mmHg and diastolic blood pressure 98.3 +/- 5.7 mmHg, affected by essential arterial hypertension of slight to moderate degree. Twenty-three subjects underwent high resolution B-mode echotomography of the common carotid artery, performed twice by the same operator within a one-week period. Treatment for 6 months with slow release Nicardipine at a dosage of 80 mg in two daily administrations was seen to be efficient in reducing systolic and diastolic blood pressure values. It also reduced the carotid-femoral pulse wave velocity. The results of our study show that 6 month's treatment with slow-release Nicardipine at 80 mg in two daily administrations, in effective reducing systolic and diastolic blood pressure values, and, to a slightly significant degree, in reducing the value of the intimal-medial thickness of the common carotid. Naturally the data which emerge from our study are preliminary and require a definitive analysis at the end the study, which is foreseen after a two year period from the enrolment of at least one hundred patients.

[Variations in plasma protein components during extracorporeal circulation]. / Variazioni delle componenti proteiche plasmatiche durante circolazione extracorporea.

In this research we have determined the behaviour of proteic plasmatic pattern and some enzymes during extracorporeal circulation and we noted a constant increase of albumin and of the ratio Alb/Glob. We observed also variations of some enzymes. Our opinion according other AA. is that this changes are determined principally by the large dose of heparin necessary during the C.E.C.
