Cognitive inhibition deficit in long COVID-19: An exploratory study.

Background And Objectives: An increasing number of research studies point toward the importance and prevalence of long-term neurocognitive symptoms following infection with COVID-19. Our objectives were to capture the prevalence of cognitive impairments from 1 to 16 months post-COVID-19 infection, assess the changes in neuropsychological functions over time, and identify factors that can predict long-term deficits in cognition.

Methodology: A cross-sectional research design was adopted to compare four sub-samples recruited over a 16-month timeframe (1-4, 5-8, 9-12, and 13-16 months).

Identifying harm reduction strategies for alcohol and drug-use in inpatient care settings and emergency departments: a scoping review protocol.

Introduction: People who use alcohol and/or drugs (PWUAD) are at high risk of medical complications, frequent hospitalisation and drug-related death following discharge from inpatient settings and emergency departments (EDs). Harm reduction strategies implemented in these settings may mitigate negative health outcomes for PWUAD. However, the scope of harm reduction strategies used globally within inpatient settings and EDs is unknown.

The Associations Between Clinical, Social, Financial Factors and Unmet Needs of Autistic Adults: Results from an Observational Study.

Background: Autism is a developmental disability that affects how individuals experience the world. Each Autistic individual experiences Autism in their own way, meaning that the level and type of assistance in their everyday lives vary widely. A shortage of programs and services tailored to Autistic adults exists worldwide, and the current gap between needs and services is likely to worsen as the growing number of Autistic children being diagnosed reach adulthood.

"We are the stakeholders with the most at stake": scientific and autism community co-researchers reflect on their collaborative experience in the CONNECT project.

Background: Little research describes the everyday challenges and needs of autistic adults. In order to fill this data gap, the CONtiNuity of carE and support for autistiC adulTs (CONNECT) project set out to learn about the health and well-being of autistic adults as well as their service and support needs. To do so, CONNECT welcomed autistic adults and caregivers of autistic adults as members of the research team, alongside researchers, policy-makers, service providers and health professionals.

Comparing the Effect of Combining Exercise with Rosuvastatin versus Atorvastatin on Lipid Profile and Functional Capacity: A Retrospective Cohort Study.

Background: Statins and exercise are recommended for managing hypercholesterolemia. However, statin types may vary in their interaction with exercise. We compared rosuvastatin versus atorvastatin combination with exercise on lipid profile and functional capacity.

Phylogenetics, patterns of genetic variation and population dynamics of Trypanosoma terrestris support both coevolution and ecological host-fitting as processes driving trypanosome evolution.

Background: A considerable amount of evidence has favored ecological host-fitting, rather than coevolution, as the main mechanism responsible for trypanosome divergence. Nevertheless, beyond the study of human pathogenic trypanosomes, the genetic basis of host specificity among trypanosomes isolated from forest-inhabiting hosts remains largely unknown.

Methods: To test possible scenarios on ecological host-fitting and coevolution, we combined a host capture recapture strategy with parasite genetic data and studied the genetic variation, population dynamics and phylogenetic relationships of Trypanosoma terrestris, a recently described trypanosome species isolated from lowland tapirs in the Brazilian Pantanal and Atlantic Forest biomes.

Incidence and risk factors for anastomotic bleeding in lower gastrointestinal surgery.

Objective: Although major anastomotic bleeding after lower gastrointestinal surgery is considered rare, it can be life-threatening if not properly managed. The objective of this study was to assess the incidence of postoperative lower gastrointestinal intraluminal bleeding and to identify its potential risk factors. This retrospective cohort study used data from charts of 314 patients who underwent digestive surgery of the colon or small intestine.

Effects of the combination of metformin and exercise on glycated hemoglobin, functional capacity, lipid profile, quality of life, and body weight.

Objective: To evaluate the impact of the combination of metformin and exercise on changes in glycated hemoglobin (HbA), functional capacity, the lipid profile, quality of life, and weight.

Methods: Data from a 12-week cardiovascular rehabilitation program (2014–2016) were retrospectively evaluated. Metformin exposure was determined through recorded prescriptions, and average minutes of exercise per week were computed from exercise logs.

Approaches to considering sex and gender in continuous professional development for health and social care professionals: An emerging paradigm.

Consideration of sex and gender in research and clinical practice is necessary to redress health inequities and reduce knowledge gaps. As all health professionals must maintain and update their skills throughout their career, developing innovative continuing professional education programs that integrate sex and gender issues holds great promise for reducing these gaps. This article proposes new approaches to partnership, team development, pedagogical theory, content development, evaluation and data management that will advance the integration of sex and gender in continuing professional development (CPD).

Redox mechanism of levobupivacaine cytostatic effect on human prostate cancer cells.

Anti-cancer effects of local anesthetics have been reported but the mode of action remains elusive. Here, we examined the bioenergetic and REDOX impact of levobupivacaine on human prostate cancer cells (DU145) and corresponding non-cancer primary human prostate cells (BHP). Levobupivacaine induced a combined inhibition of glycolysis and oxidative phosphorylation in cancer cells, resulting in a reduced cellular ATP production and consecutive bioenergetic crisis, along with reactive oxygen species generation.

Avoidance of the vaginal incision site for mesh placement in vaginal wall prolapse surgery: A prospective study.

Objective: To evaluate efficacy of a minimal surface area, vaginally-installed polypropylene tape (VPT), avoiding insertion on the incision line to treat an anterior, posterior or anteroposterior vaginal wall prolapse.

Study Design: Patients with an anterior, posterior or anteroposterior vaginal wall prolapse waiting for surgical treatment were included in the study. Primary outcome was the incidence of prolapse recurrence reported with combined outcome measures and was reported with Kaplan-Meier cumulative incidence.

Rheb regulates mitophagy induced by mitochondrial energetic status.

Mitophagy has been recently described as a mechanism of elimination of damaged organelles. Although the regulation of the amount of mitochondria is a core issue concerning cellular energy homeostasis, the relationship between mitochondrial degradation and energetic activity has not yet been considered. Here, we report that the stimulation of mitochondrial oxidative phosphorylation enhances mitochondrial renewal by increasing its degradation rate.

Mitoplasticity: adaptation biology of the mitochondrion to the cellular redox state in physiology and carcinogenesis.

Adaptation and transformation biology of the mitochondrion to redox status is an emerging domain of physiology and pathophysiology. Mitochondrial adaptations occur in response to accidental changes in cellular energy demand or supply while mitochondrial transformations are a part of greater program of cell metamorphosis. The possible role of mitochondrial adaptations and transformations in pathogenesis remains unexplored, and it has become critical to decipher the stimuli and the underlying molecular pathways.

Rationale for mitochondria-targeting strategies in cancer bioenergetic therapies.

In the 1920s, Otto Warburg first hypothesized that mitochondrial impairment is a leading cause of cancer although he recognized the existence of oxidative tumors. Likewise, Weinhouse and others in the 50s found that deficient mitochondrial respiration is not an obligatory feature of cancer and Peter Vaupel suggested in the 1990s that tumor oxygenation rather than OXPHOS capacity was the limiting factor of mitochondrial energy production in cancer. Recent studies now clearly indicate that mitochondria are highly functional in mice tumors and the field of oncobioenergetic identified MYC, Oct1 and RAS as pro-OXPHOS oncogenes.

Preservation of NADH ubiquinone-oxidoreductase activity by Src kinase-mediated phosphorylation of NDUFB10.

The tyrosine kinase Src is upregulated in several cancer cells. In such cells, there is a metabolic reprogramming elevating aerobic glycolysis that seems partly dependent on Src activation. Src kinase was recently shown to be targeted to mitochondria where it modulates mitochondrial bioenergetics in non-proliferative tissues and cells.

AICAR inhibits cancer cell growth and triggers cell-type distinct effects on OXPHOS biogenesis, oxidative stress and Akt activation.

The AMP-activated protein kinase agonist AICAR mimics a low intracellular energy state and inhibits the proliferation of cancer cells by different mechanisms, which may depend on the bioenergetic signature of these cells. AICAR can also stimulate mitochondrial biogenesis in myoblasts, neurons and HeLa cells. Yet, whether the reactivation of oxidative phosphorylation biogenesis by AICAR contributes to the growth arrest of cancer cells remains undetermined.

Antiproliferative activity of levobupivacaine and aminoimidazole carboxamide ribonucleotide on human cancer cells of variable bioenergetic profile.

We assessed the impact of ten mitoactive drugs on the viability and the proliferation of human cancer cells of variable origin and bioenergetics. A validated chemotherapeutic drug, doxorubicin, was used as a gold-standard for comparison. We also looked at the effect of these drugs on Rho(0) cells and on embryonic fibroblasts, both of which rely mainly on glycolysis to generate the vital ATP.

From analgesia to myopathy: When local anesthetics impair the mitochondrion.

The expanding utilization of local anesthesia and analgesia revealed the occurrence of myopathies induced by local anesthetics. Such iatrogenic effect encouraged anesthesiologists to study the toxicity of local anesthetics and to reevaluate their protocols in order to reduce muscle pain and dysfunction. Studies performed in rats and human cells showed that bupivacaine induces muscle histological damages with sarcomers disruption along with structural alteration of mitochondria, the powerplant of the cell.

Choosing between glycolysis and oxidative phosphorylation: a tumor's dilemma?

A considerable amount of knowledge has been produced during the last five years on the bioenergetics of cancer cells, leading to a better understanding of the regulation of energy metabolism during oncogenesis, or in adverse conditions of energy substrate intermittent deprivation. The general enhancement of the glycolytic machinery in various cancer cell lines is well described and recent analyses give a better view of the changes in mitochondrial oxidative phosphorylation during oncogenesis. While some studies demonstrate a reduction of oxidative phosphorylation (OXPHOS) capacity in different types of cancer cells, other investigations revealed contradictory modifications with the upregulation of OXPHOS components and a larger dependency of cancer cells on oxidative energy substrates for anabolism and energy production.
