Plants of the Rubiaceae Family with Effect on Metabolic Syndrome: Constituents, Pharmacology, and Molecular Targets.

Metabolic syndrome (MetS) predisposes individuals to chronic non-communicable diseases (NCDs) like type 2 diabetes (T2D), non-alcoholic fatty liver disease, atherosclerosis, and cardiovascular disorders caused by systemic inflammation, intestinal dysbiosis, and diminished antioxidant ability, leading to oxidative stress and compromised insulin sensitivity across vital organs. NCDs present a global health challenge characterized by lengthy and costly pharmacological treatments. Complementary and alternative medicine using herbal therapies has gained popularity. Approximately 350,000 plant species are considered medicinal, with 80% of the world's population opting for traditional remedies; however, only 21,000 plants are scientifically confirmed by the WHO. The Rubiaceae family is promissory for preventing and treating MetS and associated NCDs due to its rich content of metabolites renowned for their antioxidative, anti-inflammatory, and metabolic regulatory properties. These compounds influence transcription factors and mitigate chronic low-grade inflammation, liver lipotoxicity, oxidative stress, and insulin resistance, making them a cost-effective non-pharmacological approach for MetS prevention and treatment. This review aims to collect and update data that validate the traditional uses of the Rubiaceae family for treating MetS and associated NCDs from experimental models and human subjects, highlighting the mechanisms through which their extracts and metabolites modulate glucose and lipid metabolism at the molecular, biochemical, and physiological levels.

Prebiotics and Probiotics: Effects on Dyslipidemia and NAFLD/NASH and the Associated Mechanisms of Action.

BACKGROUND: Non-alcoholic fatty liver disease (NAFLD) is now considered the most common chronic liver disease worldwide. NAFLD is related to changes in lipid metabolism and is characterized by the increase or accumulation of fat in hepatocytes that may progress to nonalcoholic steatohepatitis (NASH), which leads to the appearance of inflammatory processes. Treatment consists of changes in diet, physical activity, and weight control; however, these disorders represent a health problem and require the development of novel alternatives to treatment and prevention. NAFLD/NASH are strongly associated with other disorders, such as metabolic syndrome (MetS); in fact, NAFLD is considered the hepatic manifestation of MetS. These disorders are related to other components of MetS, including dyslipidemia, which is characterized by an imbalance in blood cholesterol and triglyceride levels. Prebiotics and probiotics benefit from treating and preventing several ailments, including liver diseases. Specifically, in dyslipidemia, NAFLD, and NASH, probiotics play a fundamental role in conducting the biotransformation of primary bile acids into secondary bile acids, which generally have important activity as immunomodulators and metabolism regulators. The mechanisms of action of pre and probiotics involve the activity of bile acid receptors, such as FXR and TGR-5, and the events resulting from their activation. Therefore, prebiotics and probiotics may be reasonable options to prevent and treat metabolic- related liver diseases.

Liver cancer in Hidalgo State, Mexico: analysis of the status, risk factors and regional public health policy requirements: a cross-sectional correlational study

ABSTRACT BACKGROUND: In Latin America, liver cancer is one of the top causes of cancer mortality. It is the fifth most common cause of death among malignant tumors in Mexico and is the leading cause in Hidalgo State (43.8% of the population living in poverty). OBJECTIVE: To conduct a correlational analysis on the main risk factors for liver cancer in Hidalgo State, Mexico, including municipal disaggregation and comparison with the national level. DESIGN AND SETTING: Cross-sectional, correlational, descriptive and comparative epidemiological study using Mexican governmental databases covering 1990-2019. METHODS: A comprehensive review of the databases of the General Directorate of Health Information (DGIS) was performed to analyze official death figures, hospital discharges and national and municipal population projections, using specific search criteria defined in the Global Burden of Disease classification, based on the risk factors for liver cancer. RESULTS: Liver cancer rates showed an evident rise in Hidalgo (183%), moving from 21st place in Mexico in 1990 to 9th place in 2019. This increase was correlated with alcoholism. An increasing trend for liver cancer deaths, of 133.89%, is projected for 2030. Females and the population over 60 years of age are more affected. There are some critical regions with liver cancer death rates twice the national rate or more. CONCLUSION: Targeted effective public health strategies should be structured by identifying, characterizing and regionalizing critical marginalized municipalities that are vulnerable to alcoholism and other risk factors for liver cancer. This approach may be helpful for other states in Mexico or similar countries.

Arsenic exposure and non-carcinogenic health effects.

Inorganic arsenic (iAs) exposure is a serious health problem that affects more than 140 million individuals worldwide, mainly, through contaminated drinking water. Acute iAs poisoning produces several symptoms such as nausea, vomiting, abdominal pain, and severe diarrhea, whereas prolonged iAs exposure increased the risk of several malignant disorders such as lung, urinary tract, and skin tumors. Another sensitive endpoint less described of chronic iAs exposure are the non-malignant health effects in hepatic, endocrine, renal, neurological, hematological, immune, and cardiovascular systems. The present review outlines epidemiology evidence and possible molecular mechanisms associated with iAs-toxicity in several non-carcinogenic disorders.

Automedicación y autoprescripción / Self-medication and self-prescription

Resumen La automedicación y la autoprescripción son acciones de los pacientes; la primera como elemento del autocuidado que involucra medicamentos de venta libre y la segunda como una violación a la ley de salud, pues comprende medicamentos que solo pueden expenderse con receta. Todos los inconvenientes que se han atribuido a la automedicación en realidad lo son de la autoprescripción.

Abstract Self-medication and self-prescription are actions undertaken by patients; the former, as an element of self-care that involves over-the-counter drugs, and the latter, as a violation of the Statute of Health, since it includes drugs that can only be dispensed with a medical prescription. All the drawbacks that have been attributed to self-medication are actually associated with self-prescription.

La receta médica: ¿reflejo condicionado o reflexión consciente? / Medical prescription: conditioned reflex or conscious reflection?

Resumen Extender una receta o indicar un tratamiento suele ser la última parte de la consulta médica. Este proceso crucial puede desvirtuarse debido a múltiples factores como capacidad prescriptiva limitada, exceso de trabajo y falta de reflexión o tiempo. La información insuficiente acerca del paciente o del tratamiento afecta el proceso prescriptivo y propicia errores que pueden ser graves para la salud del enfermo. La Academia Nacional de Medicina, en consonancia con la Organización Mundial de la Salud, hace énfasis en hacer del proceso prescriptivo un ejercicio de reflexión.

Abstract Writing a prescription or indicating a treatment is usually the last part of medical consultation. This crucial process can be undermined by multiple factors such as limited prescriptive ability, overwork, and lack of reflection or time. Insufficient information about the patient or the treatment affects the prescriptive process and leads to errors that can be serious for patient health. The National Academy of Medicine, in line with the World Health Organization, emphasizes the relevance of making the prescriptive process a reflective exercise.

Beneficial and Deleterious Effects of Female Sex Hormones, Oral Contraceptives, and Phytoestrogens by Immunomodulation on the Liver.

The liver is considered the laboratory of the human body because of its many metabolic processes. It accomplishes diverse activities as a mixed gland and is in continuous cross-talk with the endocrine system. Not only do hormones from the gastrointestinal tract that participate in digestion regulate the liver functions, but the sex hormones also exert a strong influence on this sexually dimorphic organ, via their receptors expressed in liver, in both health and disease. Besides, the liver modifies the actions of sex hormones through their metabolism and transport proteins. Given the anatomical position and physiological importance of liver, this organ is evidenced as an immune vigilante that mediates the systemic immune response, and, in turn, the immune system regulates the hepatic functions. Such feedback is performed by cytokines. Pro-inflammatory and anti-inflammatory cytokines are strongly involved in hepatic homeostasis and in pathological states; indeed, female sex hormones, oral contraceptives, and phytoestrogens have immunomodulatory effects in the liver and the whole organism. To analyze the complex and interesting beneficial or deleterious effects of these drugs by their immunomodulatory actions in the liver can provide the basis for either their pharmacological use in therapeutic treatments or to avoid their intake in some diseases.

Dietary chia seeds (Salvia hispanica) improve acute dyslipidemia and steatohepatitis in rats.

Chia seeds (Salvia hispanica L.) are rich in omega fatty acids. Dyslipidemia and steatohepatitis are diseases that require effective treatments in obese and non-obese patients. The aim was to evaluate the effect of chia intake on acute tyloxapol (TI)-induced dyslipidemia, on acute carbon tetrachloride (TC)-induced steatohepatitis, and on mixed damage (TC+TI) in non-obese rats. Four experimental groups were fed for 4 weeks a diet with established rodent food (DE), and four groups were fed a diet with 15% added chia (DC). Plasma samples were analyzed for total cholesterol, triglycerides, glucose, biochemical liver damage markers, and tumor necrosis factor-α (TNF-α). Liver samples were used to quantify glycogen, catalase, lipid peroxidation, and TNF-α. A histopathological analysis was performed. DC intake partially or totally prevented steatohepatitis, and reduced lipids in the dyslipidemic groups. The hypolipidemic and hepatoprotective effects of chia may be correlated to its high content of α-linolenic acid (omega-3) and phenolics. PRACTICAL APPLICATIONS: Metabolic syndrome is associated with non-alcoholic fatty liver disease (NAFLD) and non-alcoholic steatohepatitis (NASH), which are currently the most common causes of chronic liver disease, cirrhosis, and hepatocellular carcinoma (HCC) worldwide. Dyslipidemia is a significant risk factor for NAFLD and NASH. Non-obese patients may have NAFLD or NASH. Metabolic syndrome and dyslipidemia are more strongly associated with NAFLD in non-obese than in obese patients. This is the first study evaluating the hypolipidemic and hepatoprotective effects of chia seed intake on acute dyslipidemia and/or steatohepatitis caused by the individual or combined administration of the inducers tyloxapol and carbon tetrachloride, respectively, in non-obese rats. The pharmacological effects of dietary chia are correlated to its high content of omega-3 and omega-6 (1:1), protein, dietary fiber, and phenolics. The results suggest that inclusion of chia in diets of non-obese patients with dyslipidemia and/or NAFLD/NASH may improve their health state and preventing cirrhosis or HCC.

Semi-Automated Data Labeling for Activity Recognition in Pervasive Healthcare.

Activity recognition, a key component in pervasive healthcare monitoring, relies on classification algorithms that require labeled data of individuals performing the activity of interest to train accurate models. Labeling data can be performed in a lab setting where an individual enacts the activity under controlled conditions. The ubiquity of mobile and wearable sensors allows the collection of large datasets from individuals performing activities in naturalistic conditions. Gathering accurate data labels for activity recognition is typically an expensive and time-consuming process. In this paper we present two novel approaches for semi-automated online data labeling performed by the individual executing the activity of interest. The approaches have been designed to address two of the limitations of self-annotation: (i) The burden on the user performing and annotating the activity, and (ii) the lack of accuracy due to the user labeling the data minutes or hours after the completion of an activity. The first approach is based on the recognition of subtle finger gestures performed in response to a data-labeling query. The second approach focuses on labeling activities that have an auditory manifestation and uses a classifier to have an initial estimation of the activity, and a conversational agent to ask the participant for clarification or for additional data. Both approaches are described, evaluated in controlled experiments to assess their feasibility and their advantages and limitations are discussed. Results show that while both studies have limitations, they achieve 80% to 90% precision.

Importancia de la investigación clínica independiente en la medicina: dificultades y recomendaciones.

Clinical research is the most important tool for the identification of diagnostic and therapeutic strategies that derive in higher efficacy and safety. Despite its significance, successful implementation of clinical research faces numerous difficulties, with one the most relevant being limited availability of resources for the performance of independent clinical trials. Generally, the pharmaceutical industry absorbs the costs associated with most clinical trials; however, this can generate dissociation between subjects of interest and health priorities when economic interest is the main driver of these protocols. In addition to the relevant role played by the pharmaceutical industry, it is important that government agencies favor adequate conditions, both in economic and regulatory aspects, for the implementation of independent clinical research that addresses subjects of medical and therapeutic interest, even if it does not generate corporate economic benefits.

La investigación clínica es la herramienta de mayor importancia para la identificación de estrategias diagnósticas y terapéuticas que deriven en mayor eficacia y seguridad. A pesar de su trascendencia, la implementación exitosa de la investigación clínica presenta numerosas dificultades; entre las más relevantes se encuentra la poca disponibilidad de recursos para realizar ensayos clínicos independientes. Por lo general, la industria farmacéutica absorbe los costos asociados con la mayoría de los ensayos clínicos, sin embargo, esto puede generar una disociación entre los temas de interés y las prioridades en salud, al existir interés económico como principal motivación de estos protocolos. Además del papel relevante de la industria farmacéutica, es importante que las instancias gubernamentales favorezcan las condiciones, tanto económicas como regulatorias, para la implementación de investigación clínica independiente, que aborde temas de interés médico y terapéutico, aunque no genere beneficios económicos empresariales.
