Metabolic dysregulation of tricarboxylic acid cycle and oxidative phosphorylation in glioblastoma.

Glioblastoma multiforme (GBM) exhibits genetic alterations that induce the deregulation of oncogenic pathways, thus promoting metabolic adaptation. The modulation of metabolic enzyme activities is necessary to generate nucleotides, amino acids, and fatty acids, which provide energy and metabolic intermediates essential for fulfilling the biosynthetic needs of glioma cells. Moreover, the TCA cycle produces intermediates that play important roles in the metabolism of glucose, fatty acids, or non-essential amino acids, and act as signaling molecules associated with the activation of oncogenic pathways, transcriptional changes, and epigenetic modifications. In this review, we aim to explore how dysregulated metabolic enzymes from the TCA cycle and oxidative phosphorylation, along with their metabolites, modulate both catabolic and anabolic metabolic pathways, as well as pro-oncogenic signaling pathways, transcriptional changes, and epigenetic modifications in GBM cells, contributing to the formation, survival, growth, and invasion of glioma cells. Additionally, we discuss promising therapeutic strategies targeting key players in metabolic regulation. Therefore, understanding metabolic reprogramming is necessary to fully comprehend the biology of malignant gliomas and significantly improve patient survival.

An exploratory study on the ability of manganese to supplement rotenone neurotoxicity in rats.

Parkinson's disease (PD) is a complex disorder, primarily of idiopathic origin, with environmental stressors like rotenone and manganese linked to its development. This study explores their potential interaction and resulting neurotoxicity, aiming to understand how environmental factors contribute to PD. In an eight-day experiment, male Wistar rats weighing 280-300 g were subjected to rotenone, manganese, or a combination of both. Various parameters were assessed, including body weight, behavior, serum markers, tissue damage, protein levels (tyrosine hydroxylase, Dopamine- and cAMP-regulated neuronal phosphoprotein -DARPP-32-, and α-synuclein), and mitochondrial function. Manganese heightened rotenone's impact on reducing food intake without causing kidney or liver dysfunction. However, the combined exposure intensified neurotoxicity, which was evident in augmented broken nuclei and decreased tyrosine hydroxylase and DARPP-32 levels in the striatum. While overall mitochondrial function was preserved, co-administration reduced complex IV activity in the midbrain and liver. In conclusion, our findings revealed a parallel toxic effect induced by rotenone and manganese. Notably, while these substances do not target the same dopaminergic regions, a notable escalation in toxicity is evident in the striatum, the brain region where their toxic effects converge. This study highlights the need for further exploration regarding the interaction of environmental factors and their possible impact on the etiology of PD.

Metabolic Roles of HIF1, c-Myc, and p53 in Glioma Cells.

The metabolic reprogramming that promotes tumorigenesis in glioblastoma is induced by dynamic alterations in the hypoxic tumor microenvironment, as well as in transcriptional and signaling networks, which result in changes in global genetic expression. The signaling pathways PI3K/AKT/mTOR and RAS/RAF/MEK/ERK stimulate cell metabolism, either directly or indirectly, by modulating the transcriptional factors p53, HIF1, and c-Myc. The overexpression of HIF1 and c-Myc, master regulators of cellular metabolism, is a key contributor to the synthesis of bioenergetic molecules that mediate glioma cell transformation, proliferation, survival, migration, and invasion by modifying the transcription levels of key gene groups involved in metabolism. Meanwhile, the tumor-suppressing protein p53, which negatively regulates HIF1 and c-Myc, is often lost in glioblastoma. Alterations in this triad of transcriptional factors induce a metabolic shift in glioma cells that allows them to adapt and survive changes such as mutations, hypoxia, acidosis, the presence of reactive oxygen species, and nutrient deprivation, by modulating the activity and expression of signaling molecules, enzymes, metabolites, transporters, and regulators involved in glycolysis and glutamine metabolism, the pentose phosphate cycle, the tricarboxylic acid cycle, and oxidative phosphorylation, as well as the synthesis and degradation of fatty acids and nucleic acids. This review summarizes our current knowledge on the role of HIF1, c-Myc, and p53 in the genic regulatory network for metabolism in glioma cells, as well as potential therapeutic inhibitors of these factors.

Cobalt protoporphyrin modulates antioxidant enzyme activity in the hypothalamus and motor cortex of female rats.

Cobalt protoporphyrin (CoPP) is a synthetic heme analog that has been observed to reduce food intake and promote sustained weight loss. While the precise mechanisms responsible for these effects remain elusive, earlier research has hinted at the potential involvement of nitric oxide synthase in the hypothalamus. This study aimed to delve into CoPP's impact on the activities of crucial antioxidant enzymes: superoxide dismutase (SOD), catalase, glutathione peroxidase (GPx), glutathione reductase (GR), and glutathione-S-transferase (GST) across seven distinct brain regions (hippocampus, hypothalamus, prefrontal cortex, motor cortex, striatum, midbrain, and cerebellum), as well as in the liver and kidneys. Female Wistar rats weighing 180 to 200 grams received a single subcutaneous dose of 25 µmol/kg CoPP. After six days, brain tissue was extracted to assess the activities of antioxidant enzymes and quantify malondialdehyde levels. Our findings confirm that CoPP administration triggers the characteristic effects of decreased food intake and reduced body weight. Moreover, it led to an increase in SOD activity in the hypothalamus, a pivotal brain region associated with food intake regulation. Notably, CoPP-treated rats exhibited elevated enzymatic activity of catalase, GR, and GST in the motor cortex without concurrent signs of heightened oxidative stress. These results underscore a strong connection between the antioxidant system and food intake regulation. They also emphasize the need for further investigation into the roles of antioxidant enzymes in modulating food intake and the ensuing weight loss, using CoPP as a valuable research tool.

V-EMF therapy: A new painless and completely non-invasive treatment for striae gravidarum.

BACKGROUND: The appearance of striae gravidarum (SG) during pregnancy is a common problem. The most common SG are abdominal striae, which can cause the greatest sequelae after pregnancy, and in the long term. There are several solutions to prevent and treat these striae, but not all are completely effective, and not without side effects. AIMS: The aim of this study was to evaluate the effectiveness of a treatment that applies an electromagnetic field under vacuum (V-EMF therapy) on the abdominal SG. METHODS: A retrospective analysis was conducted on the medical records of 26 women affected by abdominal SG and treated with V-EMF therapy. The results were evaluated using two different 5-point Likert Scales: one administered to the treated subjects to evaluate their satisfaction, and one to the doctors who performed the treatment, to evaluate the improvement of the striae. The presence of side effects, and the effects of sun exposure after treatment were also considered. RESULTS: Only two treated subjects rated their level of satisfaction with a Score III on the Liker Scale. Everyone else expressed higher levels of satisfaction. Only one doctor rated the improvement of the striae with a Liker scale score of III. All the others reported greater improvements. No discomfort or side effects were noted either during the individual treatment sessions, or at the end of the treatment. The striae showed a newfound ability to tan. CONCLUSIONS: V-EMF therapy proves to be a valid, safe, and effective treatment modality for SG.

Morin improves learning and memory in healthy adult mice.

BACKGROUND: Morin is a flavonoid found in many edible fruits. The hippocampus and entorhinal cortex play crucial roles in memory formation and consolidation. This study aimed to characterize the effect of morin on recognition and space memory in healthy C57BL/6 adult mice and explore the underlying molecular mechanism. METHODS: Morin was administered i.p. at 1, 2.5, and 5 mg/kg/24 h for 10 days. The Morris water maze (MWM), novel object recognition, novel context recognition, and tasks were conducted 1 day after the last administration. The mice's brains underwent histological characterization, and their protein expression was examined using immunohistochemistry and Western blot techniques. RESULTS: In the MWM and novel object recognition tests, mice treated with 1 mg/kg of morin exhibited a significant recognition index increase compared to the control group. Besides, they demonstrated faster memory acquisition during MWM training. Additionally, the expression of pro-brain-derived neurotrophic factor (BDNF), BDNF, and postsynaptic density protein 95 proteins in the hippocampus of treated mice showed a significant increase. In the entorhinal cortex, only the pro-BDNF increased. Morin-treated mice exhibited a significant increase in the hippocampus's number and length of dendrites. CONCLUSION: This study shows that morin improves recognition memory and spatial memory in healthy adult mice.

Depressive symptoms in pregnant women treated at the Hospital Infantil del Estado de Sonora / Sintomatología depresiva en embarazadas atendidas en el Hospital Infantil del Estado de Sonora

Abstract Introduction Pregnancy, being a situation of vulnerability and with its inherent changes, places women at a great risk of depression. In Mexico, the prevalence of probable depression in pregnant women treated at the Instituto Nacional de Perinatología, was 17.8%, assessed using the Edinburgh Perinatal Depression Scale (EPDS). To date, there are no data regarding this issue in Sonora. Objective To determine the prevalence of depressive symptoms in pregnant women treated at the Hospital Infantil del Estado de Sonora (México). Method An observational, descriptive, transversal, and prospective study was conducted in 2021, applying the EPDS in 168 2nd/3rd trimester pregnant women, selected by non-probabilistic sampling by consecutive cases. Sociodemographic variables, pathological/non-pathological, gynecological, and obstetrical personal history were explored. The analysis was performed using measures of central tendency and dispersion for quantitative variables; for qualitative variables, frequency and percentage; χ2 test to assess differences in distribution of depressive symptomatology by age and the rest of variables. Results A global prevalence of "probable depression" of 14.3% was determined. The majority, within 20-29 age group, with a partner and a planned/desired pregnancy. High school educational level, 50%. History of intimate partner violence, 54.2%. Almost 40%, primigravida. Substance use, denied. Overweight/obesity, in 70%. Discussion and conclusion There is a high prevalence of depressive symptoms during pregnancy, going unnoticed for reasons such as insufficient knowledge (patient/health care providers), since there is no routine screening. It is imperative to work on prevention, detection and treatment, since it entails multiple consequences at a binomial, family, and social level.

Role of Glycolytic and Glutamine Metabolism Reprogramming on the Proliferation, Invasion, and Apoptosis Resistance through Modulation of Signaling Pathways in Glioblastoma.

Glioma cells exhibit genetic and metabolic alterations that affect the deregulation of several cellular signal transduction pathways, including those related to glucose metabolism. Moreover, oncogenic signaling pathways induce the expression of metabolic genes, increasing the metabolic enzyme activities and thus the critical biosynthetic pathways to generate nucleotides, amino acids, and fatty acids, which provide energy and metabolic intermediates that are essential to accomplish the biosynthetic needs of glioma cells. In this review, we aim to explore how dysregulated metabolic enzymes and their metabolites from primary metabolism pathways in glioblastoma (GBM) such as glycolysis and glutaminolysis modulate anabolic and catabolic metabolic pathways as well as pro-oncogenic signaling and contribute to the formation, survival, growth, and malignancy of glioma cells. Also, we discuss promising therapeutic strategies by targeting the key players in metabolic regulation. Therefore, the knowledge of metabolic reprogramming is necessary to fully understand the biology of malignant gliomas to improve patient survival significantly.

Risk Factors Associated with the Development of Hospital-Acquired Infections in Hospitalized Patients with Severe COVID-19.

Recognition of risk factors for hospital-acquired infections (HAI) in patients with COVID-19 is warranted. We aimed to describe factors associated with the development of HAI in patients with severe COVID-19. We conducted a retrospective cohort study including all adult patients admitted with severe COVID-19 between March 2020 and November 2020. The primary outcome was HAI development. Bivariate and multiple logistic regression models were constructed. Among 1540 patients, HAI occurred in 221 (14%). A total of 299 episodes of HAI were registered. The most common HAI were hospital-acquired/ventilation-associated pneumonia (173 episodes) and primary bloodstream infection (66 episodes). Death occurred in 387 (35%) patients and was more frequent in patients with HAI (38% vs. 23%, p < 0.01). Early mechanical ventilation (aOR 18.78, 95% CI 12.56-28.07), chronic kidney disease (aOR 3.41, 95% CI 1.4-8.27), use of corticosteroids (aOR 2.95, 95% CI 1.92-4.53) and tocilizumab (aOR 2.68, 95% CI 1.38-5.22), age ≥ 60 years (aOR 1.91, 95% CI 1.27-2.88), male sex (aOR 1.52, 95% CI 1.03-2.24), and obesity (aOR 1.49, 95% CI 1.03-2.15) were associated with HAI. In patients with severe COVID-19, mechanical ventilation within the first 24 h upon admission, chronic kidney disease, use of corticosteroids, use of tocilizumab, age ≥ 60 years, male sex, and obesity were associated with a higher risk of HAI.

Psychometric properties of the International Society of Wheelchair Professionals' basic manual wheelchair-service-provision knowledge Test Version 1 and development of Version 2.

INTRODUCTION: Valid and reliable scores from measurement tools to test competency in basic manual wheelchair-service-provision are needed to promote good practice and support capacity building. The International Society of Wheelchair Professionals' (ISWP) Basic Test Version 1 in English, launched in 2015, is the most frequently used outcome measure tool to test basic manual wheelchair-service-provision knowledge and is part of an international certification process. Despite the wide acceptance and use of the test, its psychometric properties have not yet been established. The objectives of this study were 1) to evaluate the test's psychometric properties, 2) to develop the test's Version 2, and 3) to evaluate the content validity of the new version. METHODS: For Objective 1, methods from the Classical Test Theory were used to obtain items' difficulty, item discrimination index and domains' reliability. For Objective 2, a team of experts in wheelchair service delivery and education conducted a systematic qualitative review of the questions' text and answers and updated them using evidence-based guidelines. For Objective 3, an external team reviewed the clarity, relevance and domain allocation of the developed items using a 4-point Likert scale. Descriptive statistics were used to describe and characterize the results for each objective. Item-content (I-CVI) and Scale-content (S-CVI) validity indexes were calculated to compute content validity. RESULTS: For Objective 1, all domains in the test were below the threshold for acceptable internal consistency reliability; 80% of the total test pool (116 items from the total pool of 145) did not meet the thresholds for item difficulty and index of discrimination suggested in the literature. Of the items in the Test, 78% could be responded to intuitively and 66% did not distinguish between test-takers who were knowledgeable in the content area and those who were not. For Objective 2, experts found concerns such as items being grouped in the wrong domain, being repeated, not using person-first language, and using terms inconsistently. Thirty-four (23.4%) items were dropped and 111 (76.5%) were updated. In addition, 61 new items were developed. Members re-categorized the items and proposed a new classification of subdomains. For Objective 3, good agreement between subject-matter experts was found; the S-CVI calculated using the I-CVIs related to item clarity was 84% while using the I-CVIs related to item relevance was 98%. Only 7 items (4.1%) were deemed to be in the wrong domain and 4 items (2.3%) were considered irrelevant and dropped. CONCLUSION: The psychometric evidence in support of ISWP Basic Test Version 1 in English is suboptimal. A new set of items developed by experts in the field has shown excellent content validity. Ongoing assessments will be needed as ISWP Basic Test Version 2 is implemented and monitored.

Rotenone-Induced Model of Parkinson's Disease: Beyond Mitochondrial Complex I Inhibition.

Parkinson's disease (PD) is usually diagnosed through motor symptoms that make the patient incapable of carrying out daily activities; however, numerous non-motor symptoms include olfactory disturbances, constipation, depression, excessive daytime sleepiness, and rapid eye movement at sleep; they begin years before motor symptoms. Therefore, several experimental models have been studied to reproduce several PD functional and neurochemical characteristics; however, no model mimics all the PD motor and non-motor symptoms to date, which becomes a limitation for PD study. It has become increasingly relevant to find ways to study the disease from its slowly progressive nature. The experimental models most frequently used to reproduce PD are based on administering toxic chemical compounds, which aim to imitate dopamine deficiency. The most used toxic compounds to model PD have been 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine (MPTP) and 6-hydroxydopamine (6-OHDA), which inhibit the complex I of the electron transport chain but have some limitations. Another toxic compound that has drawn attention recently is rotenone, the classical inhibitor of mitochondrial complex I. Rotenone triggers the progressive death of dopaminergic neurons and α-synuclein inclusions formation in rats; also, rotenone induces microtubule destabilization. This review presents information about the experimental model of PD induced by rotenone, emphasizing its molecular characteristics beyond the inhibition of mitochondrial complex I.

Enhancing older adult financial decision making through the use of self-evaluation worksheets.

Financial products and options are frequently complex and difficult for consumers to understand, which, alongside positively oriented sales pitches and predatory practices, may lead to uninformed and hazardous financial decisions. While several legal reforms have been implemented to improve consumers' understanding of financial products, these modifications have only achieved mixed results. An ongoing challenge is the passive nature of such modifications, giving rise to confirmation bias-noticing the information which confirms one's belief about a product, while ignoring or not paying enough attention to the potential risks. The aim of this study was to test an implementable form of public policy to help older adults successfully navigate these financial decisions. We tested whether a self-evaluation worksheet (in conjunction with a written disclosure), involving an active manipulation of financial content, would significantly impact older adult participants' responses in an experimental reverse mortgage scenario. Forty community-dwelling, healthy older adults were randomized to one of two conditions: Control Condition (passive manipulation of financial content) and Manipulation Condition (active manipulation of financial content). In addition to completing a comprehensive neuropsychological examination, participants were administered the Reverse Mortgage Task (RM Task). Results indicated that a simple yet active manipulation-imparting accurate and understandable information regarding a complex financial product that must be further manipulated-led to the following among participants in the Manipulation Condition: (1) declines in mood; (2) superior understanding of the financial product; and (3) reduced intention of purchasing the financial product. In order for older adults to be well informed about reverse mortgages, policies must be put in place to ensure that adequate and accurate information has been not only provided but also actively processed by the individual.

El tejido adiposo, ¿solo un almacén de energía? / Adipose Tissue, Just an Energy Storage?

Resumen Cuando los alimentos cubren los requerimientos energéticos, el organismo almacena el exceso de calorías como glucógeno en el hígado y el músculo, y los triacilgliceroles en el tejido adiposo. Morfológica y funcionalmente se clasifica en blanco y pardo. El pardo tiene gran cantidad de mitocondrias, almacena los triacilgliceroles en vacuolas y disipa la energía en forma de calor; el blanco almacena energía en gotas lipídicas que ocupan la mayor parte de su volumen. Después de la ingesta de alimentos se libera insulina, lo que hace que externen GLUT4 para absorber glucosa. Los quilomicrones o las lipoproteínas de muy baja densidad (VLDL) transportan los triacilgliceroles a los depósitos de tejido adiposo. Durante el ayuno, por acción del glucagón, se liberan enzimas que degradarán a los tri, di y monogliceroles para liberar a los ácidos grasos. El tejido adiposo libera citocinas pro y antiinflamatorias, así como leptina, adiponectina que regulan el apetito y la saciedad. La proteína cinasa activada por AMP se activa como respuesta a una baja en la cantidad de energía de la célula y le ayuda a mantener un balance energético. En el adipocito promueve la degradación de los triacilgliceroles para liberar a los ácidos grasos que se emplearán como fuente energética. Se requiere de mayor cantidad de estudios para conocer más sobre la función del tejido adiposo como regulador del metabolismo y no solo como almacén de energía.

Abstract When food meets energy requirements, the body stores in the liver and in the muscle the excess of calories as glycogen and triacylglycerols in the adipose tissue. Morphologically and functionally, it is classified into white and brown tissues. Brown tissue has many large mitochondria and stores triacylglycerols in vacuoles and dissipates energy as heat; white tissue stores energy as lipid droplets that occupy most of the adipocyte's volume. After food intake insulin is released, which causes GLUT4 externalization into the cellular membrane to absorb glucose. Chylomicrons or VLDL transport triacylglycerols to adipose tissue depots. During fasting, by the action of glucagon, enzymes are released that will degrade tri-, di- and mono-glycerols to release fatty acids. Adipose tissue releases pro and anti-inflammatory cytokines, as well as leptin and adiponectin that regulate appetite and satiety. AMPK is activated in response to a decrease in the cell's energy and helps it to maintain its energetic balance. In the adipocyte, it promotes the degradation of triacylglycerols releasing fatty acids to be used as an energy source. More studies are needed to learn more about the function of adipose tissue as a regulator of the metabolism and not only as an energy storage.

["Working without patients": a new strategy to improve the glycemic control in patients with type 2 diabetes. Avoiding therapeutic inertia.] / "Trabajando sin pacientes": una nueva estrategia para mejorar el control glucémico en pacientes con diabetes mellitus tipo 2 evitando la inercia terapéutica.

OBJECTIVE: Inertia has been described as one of the causes of persistent poor glycemic control. The aim of this study was to evaluate, after one year of implementation in a health area, the effect of an intervention to improve the degree of glycemic control of patients with type 2 diabetes (DM2). METHODS: A pre-post intervention study was carried out in one health department during 2018. Health department with 222,767 inhabitants, 111 primary care physicians and 14,154 patients with DM2. Each primary care physician reviewed, outside consultation hours ("working without patients"), the electronic health record to identify patients with DM2 and with poor glycemic control, and they cited them for review. The glycemic control for the month of December 2017 and 2018 were compared, defined as the percentage of patients who reach the control objective of glycosylate hemoglobin (HbA1c). RESULTS: The proportion of patients with good glycemic control was 44.8% in 2017 and 50.1% in 2018, being the department that obtained the greatest improvement in the indicator in 2018 in the Valencian Community. The proportion of primary care physicians that had at least half of their patients with good glycemic control increased from 39% to 51% after the intervention. CONCLUSIONS: The strategy "working without patients" was associated with an improvement in the degree of glycemic control of patients with DM2.

OBJETIVO: La inercia se ha descrito como una de las causas de la persistencia del mal control glucémico. El objetivo del este estudio fue evaluar, tras un año de implantación en un área de salud, el efecto de una intervención para mejorar el grado de control glucémico de los pacientes con diabetes mellitus tipo 2 (DM2). METODOS: Estudio de intervención antes-después en un departamento de salud (área de salud) con 222.767 habitantes, 111 médicos de atención primaria y 14.154 pacientes con DM2. Cada médico de atención primaria revisó, fuera del horario de consulta ("trabajando sin pacientes"), la historia de salud electrónica para identificar pacientes con DM2 y con mal control glucémico, y los citaron para revisión. Se comparó el control glucémico del mes de diciembre de 2017 y 2018 definido como porcentaje de pacientes que alcanza objetivo de control de hemoglobina glicosilada (HbA1c). RESULTADOS: La proporción de pacientes con buen control glucémico fue de 44,8% en 2017 y 50,1% en 2018, siendo el departamento que obtuvo la mayor mejora del indicador en 2018 en la Comunidad Valenciana. La proporción de médicos de atención primaria que tenían al menos la mitad de sus pacientes con buen control glucémico pasó del 39% al 51% tras la intervención. CONCLUSIONES: La estrategia "trabajando sin pacientes" se asoció a una mejora del grado de control glucémico de los pacientes con DM2.

Medication adherence is influenced by resilience in patients with systemic lupus erythematosus.

OBJECTIVE: Evidence on the relationship between resilience and medication adherence in systemic lupus erythematosus (SLE) patients is lacking. We aimed to examine the impact of resilience on medication adherence in SLE patients. METHOD: In a cross-sectional analysis SLE outpatients were assessed for resilience (Connor-Davison Resilience Scale, CD-RISC), depressive symptoms (CES-D) and medication adherence (Compliance Questionnaire for Rheumatology [CQR]). The disease activity index (mexSLEDAI) and damage (SLICC Damage Index) were administered. Factors independently associated with adherence were identified using multivariate logistic regression. RESULTS: Of the 157 patients, 152 (96.8%) were female with a median age of 45.9 (IQR: 39.0-55.5) years and disease duration of 14 (IQR: 10.0-19.0) years. Medication adherence (CQR ≥80%) and depressive symptoms were found in 74.5% and 43.9% of patients, respectively. Adherent patients had a lower CES-D score and a higher CD-RISC score. In the multivariate analysis adjusting for demographic and clinical confounders, resilience and older age protected against non-adherence (OR 0.96, [95% CI 0.94-0.99] and OR 0.96 [95% CI 0.93-0.98], respectively). CONCLUSION: In SLE patients, resilience and older age, which possibly associated with better medication adherence, may protect against non-adherence.
