Psychotic and nonpsychotic mood disorders in autoimmune encephalitis: diagnostic issues and research implications

Recent research on autoimmune disorders suggests additional links between systemic and central nervous system (CNS) pathophysiology, among which the identification of antibody-induced limbic encephalitis provided the strongest evidence for the potential involvement of autoimmunity in the pathogenesis of severe mood and psychotic symptoms. In these illnesses, psychiatric symptoms predominate in the initial phase of the disorder in up to 70% of the cases, and they often lead patients to early psychiatric evaluation. For this reason, it is very important to increase the limited knowledge among psychiatrists about these autoimmune neuropsychiatric diseases, which can mimic psychiatric syndromes, in particular, those typically presented in severe mood disorders and schizophrenia. On the other hand, similarities in clinical presentation suggest that neuroinflammation and systemic immune dysregulation may play a role in the pathophysiology of severe mood and psychotic disorders. A complex interaction between periphery and immune cells of the CNS may result in cellular damage through mechanisms involving excitotoxicity, oxidative stress, and mitochondrial dysfunction. These pathways are possibly shared between comorbid medical disorders and severe mood and psychotic disorders and may reflect common underlying vulnerability

Coeliac disease: no difference in milk and dairy products consumption in comparison with controls

BackgroundNutritional deficiencies are common in patients with coeliac disease and they can cause osteopenia among other associated diseases. Reduced consumption of milk and dairy products may play a major role in determining low bone mass in patients with coeliac disease.AimWe aimed to investigate milk and dairy products consumption in patients with coeliac disease compared with the general population.MethodsWe examined the average consumption of milk and dairy products and the reasons for not consuming them. An online survey was sent by email to patients with coeliac disease on a gluten-free diet and aged 18–75. Matched controls were selected among volunteers who responded to the survey posted on the public access sites. Differences in frequencies and means between the two groups were calculated using the χ2 test and t-test, respectively. All tests were two-tailed with a significance level set at p<0.05.Results176 patients with coeliac disease and 528 controls participated in the study. We found that 22.2% of the patients with coeliac disease and 19.9% of controls did not drink fluid milk on a regular basis; lactose-free milk was preferred by 20.4% of the patients with coeliac disease and by 19% of controls (p=0.69). Only a minority of patients with coeliac disease contacted a doctor before having lactose-free milk, despite this being led by the presence of gastrointestinal symptoms. More patients with coeliac disease than the general population reported a breath test before avoiding milk and dairy products.ConclusionsThere is no significant difference between patients with coeliac disease and controls in regular milk consumption. Follow-up visits for patients with coeliac disease could avoid unnecessary dietary restrictions

Oxidation of lactate to pyruvate mediates the cytotoxic potential of physical plasma-treated saline solutions in ovarian cancer

Epithelial ovarian cancer (EOC) is the most common type of gynecological tumor, presenting poor prognosis at diagnosis and with recurrences being frequently observed. Reactive species generated by physical plasma and transferred into liquids have shown promising results in cancer therapy. Recently, Ringer's lactate solution was exposed to plasma showing selective anticancer activity on EOC cells. In this work, we compared the effect of plasma treatment, using the kINPen plasma jet, on Ringer's saline and Ringer's lactate solution. These two plasma-treated liquids were analyzed chemically by quantifying reactive species and the extent of lactate oxidation. The biological efficiency of the plasma-treated liquids was explored in EOC cells. The results show that lactate is affected by plasma treatment, displaying a reduction of cytotoxic potential.This publication is based upon work from COST Action Action CA20114 PlasTHER “Therapeutical Applications of Cold Plasmas,” supported by COST.

Trayectorias educativas no lineales. Un estudio de situación en el Partido de Gral. Pueyrredon

Este trabajo indaga sobre las trayectorias escolares de los niños adolescentes y jóvenes de los niveles educativos inicial, primario, secundario y terciario del Partido de General Pueyrredon a partir de las estadísticas oficiales suministradas por la DGE de la Provincia de Buenos Aires (2020) y la Secretaria de Educación de la Municipalidad de Gral. Pueyrredon (2020). Aquí se hace especial observación en el nivel secundario.También se aborda el comportamiento de la matrícula, a partir del escenario postpandemia, respecto a la implementación de un programa puesto en marcha por el estado provincial durante 2021 (Programa+ATR) como intento desde las políticas públicas, de revincular a lxs alumnxs del nivel primario y secundario con la escuela y el Programa Universitario de Escuelas de Educación Profesional, destinado a la capacitación laboral específica de jóvenes y que  articula la universidad pública con los sindicatos y sectores productivos. Se aspira a poner en cuestión algunas de las ideas que circulan en el imaginario docente acerca de las causas del llamado “fracaso escolar”, tradicionalmente atribuido a determinados perfiles de alumnos y/o ciertas particularidades de sus familias de origen.A partir de la observación de los datos cuantitativos se procura interpretar y relacionar dos dimensiones que se encuentran en la base de los fenómenos de la repitencia, el abandono y la sobreedad, tales como: la estructuración del sistema educativo y las dinámicas de selección del alumnado que atraviesa al sistema

Prevalence of eating disorders in adults with celiac disease.

Abstract Background. Symptoms of celiac disease negatively impact social activities and emotional state. Aim was to investigate the prevalence of altered eating behaviour in celiac patients. Methods. Celiac patients and controls completed a dietary interview and the Binge Eating Staircases, Eating Disorder Inventory (EDI-2), Eating Attitudes Test, Zung Self-Rating Depression Scale, State Trait Anxiety Inventory Forma Y (STAI-Y1 and STAI-Y2), and Symptom Check List (SCL-90). Results. One hundred celiac adults and 100 controls were not statistically different for gender, age, and physical activity. STAI-Y1 and STAI-Y2, Somatization, Interpersonal, Sensitivity, and Anxiety scores of the SLC-90 were higher in CD patients than controls. EDI-2 was different in pulse thinness, social insecurity, perfectionism, inadequacy, ascetisms, and interpersonal diffidence between CD and HC women, whilst only in interceptive awareness between CD and HC men. A higher EAT-26 score was associated with the CD group dependently with gastrointestinal symptoms. The EAT26 demonstrated association between indices of diet-related disorders in both CD and the feminine gender after controlling for anxiety and depression. Conclusion. CD itself and not gastrointestinal related symptoms or psychological factors may contribute pathological eating behavior in celiac adults. Eating disorders appear to be more frequent in young celiac women than in CD men and in HC

Similar reduction of cholesterol-adjusted Vitamin E serum levels in simple steatosis and non-alcoholic steatohepatitis

OBJECTIVES: Reduced vitamin E levels have been reported in patients with non-alcoholic steatohepatitis (NASH), but no conclusive data on patients with simple steatosis (SS) are available. Aim of this study was to investigate the association betweenserum vitamin E levels and SS. METHODS: A cohort of 312 patients with cardio-metabolic risk factors was screened for liver steatosis by ultrasonography (US). We reasonably classified as SS patients with US-fatty liver, normal liver function tests (LFTs) and with Cytokeratin 18 o246 mIU/ml. Liver biopsy was performed in 41 patients with US-fatty liver and persistent elevation of LFTs (46 months). Serum cholesterol-adjusted vitamin E (Vit E/chol) levels were measured. RESULTS: Mean age was 53.9±12.5 years and 38.4% were women. Non-alcoholic fatty liver disease (NAFLD) was detected at US in 244 patients; of those 39 had biopsy-proven NASH and 2 borderline NASH. Vit E/chol was reduced in both SS (3.4±2.0, Po0.001), and NASH (3.5±2.1, P=0.006) compared with non-NAFLD patients (4.8±2.0 μmol/mmol chol). No difference was found between SS and NASH (P=0.785). After excluding patients with NASH, a multivariable logistic regression analysis found that Vit E/chol (odds ratio (OR): 0.716, 95% confidence interval (CI) 0.602–0.851, Po0.001), alanine aminotransferase (ALT, OR: 1.093, 95% CI 1.029–1.161, P=0.004), body mass index (OR: 1.162, 95% CI 1.055–1.279, P=0.002) and metabolic syndrome (OR: 5.725, 95% CI 2.247–14.591, Po0.001) were factors independently associated with the presence of SS. CONCLUSIONS: Reduced vitamin E serum levels are associated with SS, with a similar reduction between patients with SS and NASH, compared with non-NAFLD patients. Our findings suggest that the potential benefit of vitamin E supplementation should be investigated also in patients with SS

LOX Gene Transcript Accumulation in Olive (Olea europaea L.) Fruits at Different Stages of Maturation: Relationship between Volatile Compounds, Environmental Factors, and Technological Treatments for Oil Extraction

The quality of olive oil is influenced by genetic and environmental factors and by the maturation state of drupes, but it is equally affected by technological treatments of the process. This work investigates the possible correlation between olive LOX gene transcript accumulation, evaluated in fruits collected at different stages of maturation, and chemical biomarkers of its activity. During olive fruit ripening, the same genotype harvested from two different farms shows a positive linear trend between LOX relative transcript accumulation and the content of volatile compounds present in the olive oil aroma. Interestingly, a negative linear trend was observed between LOX relative transcript accumulation and the content of volatile compounds present in the olive pastes obtained from olive fruits with and without malaxation. The changes in the olive LOX transcript accumulation reveal its environmental regulation and suggest differential physiological functions for the LOXs

Effects of cryopreservation on the mitochondrial bioenergetics of bovine sperm

This study evaluated the bioenergetic map of mitochondria metabolism in cryopreserved bovine sperm. The detected oligomycin-sensitive basal respiration supported ATP production; frozen-thawed spermatozoa were found to have a coupling efficiency higher than 0.80. Cell respiration, however, was not stimulated by the protonophoric action of FCCP, as its titration with 1, 2, 4 and 6 mu M did not stimulate the uncoupling activity on oxidative phosphorylation as highlighted by unresponsive oxygen consumption. The unusual effect on the stimulation of maximal respiration was not related to fibronectin- or PDL-coated plates used for cellular metabolism analysis. Conversely, irradiation of frozen-thawed bovine sperm with the red light improved mitochondrial parameters. In effect, the maximal respiration of red-light-stimulated sperm in PDL-coated plates was higher than the non-irradiated. In spite of this, red-light irradiation had no impact on membrane integrity and mitochondrial activity evaluated by epifluorescence microscopy

Bloating and functional gastro-intestinal disorders: Where are we and where are we going?

Bloating is one of the most common and bothersome symptoms complained by a large proportion of patients. This symptom has been described with various definitions, such as sensation of a distended abdomen or an abdominal tension or even excessive gas in the abdomen, although bloating should probably be defined as the feeling (e.g. a subjective sensation) of increased pressure within the abdomen. It is usually associated with functional gastrointestinal disorders, like irritable bowel syndrome, but when bloating is not part of another functional bowel or gastrointestinal disorder it is included as an independent entity in Rome III criteria named functional bloating. In terms of diagnosis, major difficulties are due to the lack of measurable parameters to assess and grade this symptom. In addition, it is still unclear to what extent the individual patient complaint of subjective bloating correlates with the objective evidence of abdominal distension. In fact, despite its clinical, social and economic relevance, bloating lacks a clear pathophysiology explanation, and an effective management endorsement, turning this common symptom into a true challenge for both patients and clinicians. Different theories on bloating etiology call into questions an increased luminal contents (gas, stools, liquid or fat) and/or an impaired abdominal empting and/or an altered intra-abdominal volume displacement (abdomino-phrenic theory) and/or an increased perception of intestinal stimuli with a subsequent use of empirical treatments (diet modifications, antibiotics and/or probiotics, prokinetic drugs, antispasmodics, gas reducing agents and tricyclic antidepressants). In this review, our aim was to review the latest knowledge on bloating physiopathology and therapeutic options trying to shed lights on those processes where a clinician could intervene to modify disease course
