Outcomes of a Virtual Day Treatment Program for Adults With Eating Disorders-Comparison With In-Person Day Treatment.

Objective: Previous studies have indicated that virtual treatments for eating disorders (EDs) are roughly as effective as are in-person treatments; the present nonrandomized study aimed to expand on the current body of evidence by comparing outcomes from a virtual day treatment program with those of an in-person program in an adult ED sample.

Method: Participants were 109 patients who completed at least 60% of day treatment sessions (n = 55 in-person and n = 54 virtual). Outcome measures included ED and comorbid symptoms, and motivation.

Postmortem concentrations for total blood carbon monoxide (TBCO) as a novel biomarker for carbon monoxide (CO) poisonings.

Total blood carbon monoxide (TBCO) showed promising results in improving accuracy of CO determinations in blood and presenting better stability to different storage conditions. Therefore, it was proposed as an alternative biomarker to carboxyhemoglobin (COHb) for CO poisoning diagnosis. However, given that current interpretation reference values exist for COHb only, it is difficult to implement TBCO analysis in routine.

T Cell Receptor Sequences Amplified during Severe COVID-19 and Multisystem Inflammatory Syndrome in Children Mimic SARS-CoV-2, Its Bacterial Co-Infections and Host Autoantigens.

Published hypervariable region V-beta T cell receptor (TCR) sequences were collected from people with severe COVID-19 characterized by having various autoimmune complications, including blood coagulopathies and cardiac autoimmunity, as well as from patients diagnosed with the Kawasaki disease (KD)-like multisystem inflammatory syndrome in children (MIS-C). These were compared with comparable published v-beta TCR sequences from people diagnosed with KD and from healthy individuals. Since TCR V-beta sequences are supposed to be antigens that induce clonal expansion, it was surprising that only a quarter of the TCR sequences derived from severe COVID-19 and MIS-C patients SARS-CoV-2 proteins.

DNA methylation in people with anorexia nervosa: Epigenome-wide patterns in actively ill, long-term remitted, and healthy-eater women.

Objectives: Recent studies have reported altered methylation levels at disorder-relevant DNA sites in people who are ill with Anorexia Nervosa (AN) compared to findings in people with no eating disorder (ED) or in whom AN has remitted. The preceding implies state-related influences upon gene expression in people with AN. This study further examined this notion.

Barriers and facilitators to providing autonomy supportive counselling to individuals seeking treatment for an eating disorder.

Purpose: Self-determination theory suggests that autonomous motivation for change (i.e., motivation that is internal and self-endorsed) can be enhanced in therapeutic contexts by clinicians acting in an autonomy supportive manner.

Predictors of non-completion of a day treatment program for adults with eating disorders.

Although treatment dropout is common among patients with eating disorders, very few studies have examined predictors of non-completion in day treatment. We investigated various potential predictors of dropout from adult day treatment. Participants were 295 adult patients with a diagnosis of Anorexia Nervosa (restricting or binge-eating/purging subtype), Bulimia Nervosa (BN), Other Specified Feeding or Eating Disorder, or Avoidant Restrictive Food Intake Disorder.

Reticulon-1C Involvement in Muscle Regeneration.

Skeletal muscle is a very dynamic and plastic tissue, being essential for posture, locomotion and respiratory movement. Muscle atrophy or genetic muscle disorders, such as muscular dystrophies, are characterized by myofiber degeneration and replacement with fibrotic tissue. Recent studies suggest that changes in muscle metabolism such as mitochondrial dysfunction and dysregulation of intracellular Ca homeostasis are implicated in many adverse conditions affecting skeletal muscle.

In-person versus virtual therapy in outpatient eating-disorder treatment: A COVID-19 inspired study.

Objective: Findings show virtual therapy (conducted using internet-based videoconferencing techniques) to be a viable alternative to in-person therapy for a variety of mental-health problems. COVID-19 social-distancing imperatives required us to substitute virtual interventions for in-person sessions routinely offered in our outpatient eating disorder (ED) program-and afforded us an opportunity to compare the two treatment formats for clinical efficacy.

Methods: Using self-report assessments, we compared outcomes in a historical sample of 49 adults with heterogeneous EDs (treated in-person over 10-14 weeks in individual and group therapies) to those of 76 patients receiving comparable virtual treatments, at distance, during the COVID-19 outbreak.

Clinical outcomes of a community clinic-based lifestyle change program for prevention and management of metabolic syndrome: Results of the 'Vida Sana/Healthy Life' program.

Introduction: As US Hispanic populations are at higher risk than non-Hispanics for cardiovascular disease and Type 2 diabetes targeted interventions are clearly needed. This paper presents the four years results of the Vida Sana Program (VSP), which was developed and is implemented by a small clinic serving mostly Spanish-speaking, limited literacy population.

Methods: The eight-week course of interactive two-hour sessions taught by Navegantes, bilingual/cultural community health workers, was delivered to participants with hypertension, or high lipids, BMI, waist circumference, glucose or hemoglobin A1C (A1C).

Transglutaminase Type 2 is Involved in the Hematopoietic Stem Cells Homeostasis.

Type 2 transglutaminase (TG2) is a multifunctional protein involved in various biological processes playing a key regulatory role in cell homeostasis such as cell death and autophagy. New evidence is emerging that support an important role of autophagy in regulating normal hematopoiesis. Prompted by these findings, in this study we investigated in vivo involvement of TG2 in mouse hematopoiesis under normal or nutrient deprivation conditions.

Reticulon Homology Domain-Containing Proteins and ER-Phagy.

The endoplasmic reticulum (ER) is a dynamic membrane system comprising different and interconnected subdomains. The ER structure changes in response to different stress conditions through the activation of a selective autophagic pathway called ER-phagy. This represents a quality control mechanism for ER turnover and component recycling.

New strategy for carbon monoxide poisoning diagnosis: Carboxyhemoglobin (COHb) vs Total Blood Carbon Monoxide (TBCO).

Diagnosis of carbon monoxide (CO) poisonings has always been a challenging task due to the susceptibility to alterations of the optical state and degradation of blood samples during sampling, transport and storage, which highly affects the analysis with spectrophotometric methods. Methodological improvements are then required urgently because of increased reports of cases with discrepancies between results of the measured biomarker carboxyhemoglobin (COHb) and reported symptoms. Total blood CO (TBCO) measured chromatographically was thus proposed in a previous study as alternative biomarker to COHb.

Modulation of autophagy by RTN-1C: role in autophagosome biogenesis.

The endoplasmic reticulum (ER) is a key organelle fundamental for the maintenance of cellular homeostasis and to determine the cell's fate under stress conditions. Among the known proteins that regulate ER structure and function there is Reticulon-1C (RTN-1C), a member of the reticulon family localized primarily on the ER membrane. We previously demonstrated that RTN-1C expression affects ER function and stress condition.

Community clinic-based lifestyle change for prevention of metabolic syndrome: Rationale, design and methods of the 'Vida Sana/healthy life' program.

Purpose: and Objectives: The risk of diseases associated with Metabolic Syndrome (MetS) is higher for Hispanics living in the northeastern United States than for other racial and ethnic groups. Higher risk of diabetes, high blood lipids, obesity and limited access to continuity of care are all factors that also contribute to disproportionately poorer chronic disease outcomes for Hispanics.

Intervention Approach: This article describes the planning and implementation of, and evaluation plans for the Vida Sana Program (VSP), a community-based group intervention created to address the identified MetS risks by encouraging healthier diet and physical activity behaviors among a low-income, largely Spanish speaking, and literacy limited uninsured population.

Total Blood Carbon Monoxide: Alternative to Carboxyhemoglobin as Biological Marker for Carbon Monoxide Poisoning Determination.

As one of the most abundant toxic contaminants in the atmosphere, carbon monoxide (CO) plays a significant role in toxicology and public health. Every year, around half of the accidental non-fire-related poisoning deaths are attributed to CO in the USA, UK and many other countries. However, due to the non-specificity of the symptoms and often encountered inconsistency of these with the results obtained from measurements of the biomarker for CO poisonings, carboxyhemoglobin (COHb), there is a high rate of misdiagnoses.

Carbon monoxide analysis method in human blood by Airtight Gas Syringe - Gas Chromatography - Mass Spectrometry (AGS-GC-MS): Relevance for postmortem poisoning diagnosis.

Carbon monoxide is one of the most abundant toxic air pollutants. Symptoms of a CO intoxication are non-specific, leading to a high number of misdiagnosed CO poisoning cases that are missing in the disease statistics. The chemical nature of the molecule makes it difficult to detect for long periods and at low levels, thus requiring a very accurate and sensitive method.

The spermidine analogue GC7 (N1-guanyl-1,7-diamineoheptane) induces autophagy through a mechanism not involving the hypusination of eIF5A.

The exogenous administration of spermidine promotes longevity in many model organisms. It has been proposed that this anti-age activity of spermidine is related to this polyamine's ability to promote autophagy. Since spermidine is the substrate for the eIF5A post-translational modification by hypusination, we asked ourselves whether mature eIF5A may represent the link between spermidine and autophagy induction.

Inhibition of cell proliferation, migration and invasion of B16-F10 melanoma cells by α-mangostin.

In this study, we have evaluated the potential antineoplastic effects of α-mangostin (α-M), the most representative xanthone in Garcinia mangostana pericarp, on melanoma cell lines. This xanthone markedly inhibits the proliferation of high-metastatic B16-F10 melanoma cells. Furthermore, by deeply analyzing which steps in the metastatic process are influenced by xanthone it was observed that α-M strongly interferes with homotypic aggregation, adhesion, plasticity and invasion ability of B16-F10 cells, probably by the observed reduction of metalloproteinase-9 activity.

Vida Sana: a lifestyle intervention for uninsured, predominantly Spanish-speaking immigrants improves metabolic syndrome indicators.

Metabolic syndrome is an increasingly common condition that can contribute to the development of type 2 diabetes and cardiovascular disease. 35 % of adults living in the United States meet the criteria for having metabolic syndrome, with that number being even higher in populations with health disparities. We describe a 'healthy lifestyles' program implemented at a free clinic serving a predominantly Hispanic cohort of low-income, uninsured individuals living in Providence, Rhode Island.

Aloe-emodin as antiproliferative and differentiating agent on human U937 monoblastic leukemia cells.

Aims: Aloe-emodin (AE), a plant derived anthraquinone, has been shown to have anticancer activity in various human cancer cell lines. We have recently reported that AE possesses a differentiative potential on melanoma cells. The purpose of this study was to investigate the possible modulation of defined markers of monocytic differentiation of AE on human U937 cell line.

The dynamic interaction of AMBRA1 with the dynein motor complex regulates mammalian autophagy.

Autophagy is an evolutionary conserved catabolic process involved in several physiological and pathological processes such as cancer and neurodegeneration. Autophagy initiation signaling requires both the ULK1 kinase and the BECLIN 1-VPS34 core complex to generate autophagosomes, double-membraned vesicles that transfer cellular contents to lysosomes. In this study, we show that the BECLIN 1-VPS34 complex is tethered to the cytoskeleton through an interaction between the BECLIN 1-interacting protein AMBRA1 and dynein light chains 1/2.

Antitumor properties of aloe-emodin and induction of transglutaminase 2 activity in B16-F10 melanoma cells.

Aims: Aloe-emodin (AE), a natural hydroxyanthraquinone compound, has been reported as a potential anticancer agent. We studied the antineoplastic properties of AE on highly metastatic B16-F10 melanoma murine cells.

Main Methods: Cell proliferation was assessed by cell counting and viability was investigated using MTT and Trypan Bleu exclusion tests.

Transglutaminase 2 is involved in autophagosome maturation.

Autophagy is a highly conserved cellular process responsible for the degradation of long-lived proteins and organelles. Autophagy occurs at low levels under normal conditions, but it is enhanced in response to stress, e.g.
