RESUMEN

This study evaluated the prevalence of concomitant use of herbal products for weight loss (HPWL) and allopathic medicine. Factors associated with the prevalence, adverse reactions, and the alteration of medication adherence with the concomitant use of HPWL alone and in combination with allopathic medicine, were assessed. The study was descriptive and cross-sectional using a questionnaire conducted among people with overweight or obesity (n=662) from five cities of Central Mexico. Adherence to medications was measured using the Morisky Medication Adherence Scale. The prevalence of adverse reactions induced by the concomitant use of HPWL, and allopathic medicine was 25.3%. The use of HPWL affected medication adherence by 68%. There is a high prevalence (45.2%) of concomitant use of HPWL and allopathic medicine in people with overweight or obesity in Central Mexico. The concomitant use of HPWL and allopathic medicine induces adverse reactions, mainly gastrointestinal, and thus, medication adherence is affected.

RESUMEN

BACKGROUND: Pediatric self-medication is based on the subjective interpretation of symptoms in children by the mother or an adult, the decision to self-medicate is made by a third party. The objective of this work is to provide information on the factors and practices associated with the self-medication of children among parents in Mexico. METHODS: A cross-sectional and descriptive study was conducted between June 2020 and December 2021 on Mexican parents with children under 12 years of age. Online questionnaires were completed with sections on sociodemographic characteristics, use of medicines or medicinal plants and their treated symptoms, sources of collection, and their recommendation. RESULTS: A total of 9905 online surveys were completed with representation from the 32 states of Mexico, and the prevalence of self-medication was 49.6% (n = 4908). Associated factors were age, having two or more children, children with chronic illnesses, medium educational level, unemployment or employment unrelated to health, medium and high socioeconomic level, and lack of medical security. Respondents self-medicated their children on the recommendation of a family member or friend (55.8%), and own initiative (28%). The most used medication was VapoRub (61.3%), followed by paracetamol (56.9%) and chamomile (33.1%), and the most prevalent symptoms were flu/flow (47.7%) followed by cough (34.2%). The main reasons were perceiving symptoms as not serious (69.9%) and reusing medications (51.9%). CONCLUSIONS: There is a high prevalence of self-medication in children in Mexico, mainly associated with children with chronic diseases and families with three or more children.

RESUMEN

Zygomycetes are ubiquitous saprophytes in natural environments which transform organic matter. Some zygomycetes of gender Mucor have attracted interest in health sector. Due to its ability as opportunistic microorganisms infecting immuno-compromised people and to the few available pharmacological treatments, the mucormycosis is receiving worldwide attention. Concerning to the pharmacological treatments, some triazole-based compounds such as fluconazole are extensively used. Nevertheless, we focused in the quinolines since they are broadly used models for the design and development of new synthetic antifungal agents. In this study, the fungistatic activity on M. circinelloides of various 2-aryl-4-aryloxyquinoline-based compounds was discovered, and in some cases, it resulted better than reference compound fluconazole. These quinoline derivatives were synthesized via the Csp2-O bond formation using diaryliodonium(III) salts chemistry. A QSAR study was carried out to quantitatively correlate the chemical structure of the tested compounds with their biological activity. Also, a docking study to identify a plausible action target of our more active quinolines was carried out. The results highlighted an increased activity with the fluorine- and nitro-containing derivatives. In light of the few mucormycosis pharmacological treatments, herein we present some non-described molecules with excellent in vitro activities and potential use in the mucormycosis treatment.

RESUMEN

OBJECTIVE: This study aims to assess the prevalence of herbal medicine (HM) use and factors influencing HM usage including the identification of the main plants consumed by patients with type 2 diabetes mellitus (T2DM) in central-western Mexico. DESIGN: A total of 1862 patients with diabetes were surveyed in public and private hospitals in four states (Guanajuato, Jalisco, Michoacan, and San Luis Potosi) of the central-western region of Mexico. The chi-square test was used to assess associations between HM use and demographic characteristics, such as glucose levels, presence of complications and comorbidities, as well as the selected therapy to treat T2DM. RESULTS: The prevalence of HM use (59.2%) in patients with T2DM was mainly associated with education level (p = 0.001), time of diagnosis of T2DM (p = 0.004), presence of complications (p < 0.001) and comorbidities (p = 0.018) and the use of insulin (p < 0.001). These patients report a higher consumption of herbal medicine compared to those on glycemic control (p < 0.001). The most frequently used medicinal plants to treat T2DM were nopal (54.9%), moringa (26.7%), and aloe (22.1%). CONCLUSION: The prevalence of HM use to treat T2DM in west-central Mexico is high (59.2%) and its consumption is mostly carried out without the recommendation of a health professional (91.9%). The use of HM increases mainly when the patient uses insulin, during complications of the disease or in patients with an inadequate glycemic control.

RESUMEN

BACKGROUND: The aim of this study was to assess the frequency of allopathic and complementary medicine use for preventing the infection with SARS-CoV-2 in Mexico. A descriptive and cross-sectional study was conducted using an online questionnaire among general adult population (n = 16,724) of the 32 Mexican states from March to November 2020. METHODS: The factors associated with the use, self-medication practice, and adverse reactions due the consumption of allopathic and complementary medicine to prevent infection with SARS-CoV-2 virus were assessed using a structured questionnaire. The suspected adverse reactions associated with the use of drugs or complementary medicine were reported. RESULTS: The prevalence (42.9%) of allopathic and/or complementary medicine use for preventing SARS-CoV-2 infection was mainly associated with unemployment [OR:2.026 (1.722-2.283)]. Acetaminophen (n = 2272) and vitamin C (n = 3252) were the main allopathic and complementary medicine products used to prevent SARS-CoV-2 infection, respectively. The prevalence of self-medication and adverse reactions was 35.3% and 4.8%, respectively. Self-medication [OR:1.930 (1.633-2.282)] and adverse reactions [OR:2.603 (2.015-3.363)] were mainly associated with individuals of low socioeconomic status. Hydroxychloroquine (21.2%) and chloroquine (15.2%) showed the highest prevalence of adverse reactions, which were mainly related to gastrointestinal disorders. CONCLUSION: The use of medications and complementary medicine to prevent SARS-CoV-2 infection is prevalent (almost one-half of the respondents) among Mexican population, and it is mainly associated with unemployment. Self-medication and the adverse reactions derived from self-medication are also prevalent and seem to be influenced by low socioeconomic status.

RESUMEN

ETHNOPHARMACOLOGICAL RELEVANCE: There are plant species used in the Mexican traditional medicine for the empirical treatment of anxiety and depression. AIM OF THE STUDY: This work assessed the prevalence of self-medication with medicinal plants and the prevalence of the concomitant use of prescribed psychiatric drugs and medicinal plants for treating symptoms associated with anxiety and depression during the Covid-19 lockdown in Mexico. MATERIALS AND METHODS: The suspected adverse reactions associated with drug-herb interactions were assessed. The factors associated with self-medication, the concomitant use of herb-drug combinations, and the presence of adverse reactions due their combined use is also reported. The study was descriptive and cross-sectional using an online questionnaire conducted among population with symptoms associated with anxiety and depression (n = 2100) from seven states of central-western Mexico. RESULTS: The prevalence of the use of herbs (61.9%) and the concomitant use of drug-herb combinations (25.3%) were associated with being diagnosed with mental illness [OR:2.195 (1.655-2.912)] and the use of psychiatric medications [OR:307.994 (178.609-531.107)], respectively. The presence of adverse reactions (n = 104) by the concomitant use of drug-herb combinations was associated with being unemployed [p = 0.004, OR: 3.017 (1.404-6.486)]. CONCLUSION: Health professionals should be aware if their patients concomitantly use medicinal plants and psychiatric drugs. Public health campaigns should promote the possible adverse reactions that might produce the concomitant use of drug-herb combinations for mental illnesses.

RESUMEN

This work describes the neuropharmacological (sedative, anxiolytic, antidepressant, and anticonvulsant) actions of Gardenin A (GA) (0.1-25 mg/kg p.o.), a flavonoid found in medicinal plants. The sedative effects of GA were assessed with the pentobarbital-induced sleep test. The anxiolytic actions of GA were evaluated with the elevated plus-maze, the light-dark box test, the exploratory cylinder assay, and the open field test. Motor coordination was evaluated with the rotarod test and the open field test. The antidepressant-like actions of GA were evaluated with the tail suspension test and forced swimming test. The mechanisms of the anxiolytic-like and antidepressant-like effects of GA were assessed using inhibitors of neurotransmission pathways. The anticonvulsant activity of GA was evaluated with the strychnine-induced seizure test. The sedative effects of GA were evident only at a dose of 25 mg/kg, which increased the duration of sleep but did not alter sleep onset. GA showed anxiolytic-like actions with activity comparable to that of clonazepam in all experimental tests. The GABAA receptor antagonist bicuculline reversed the anxiolytic-like effects of GA. Furthermore, GA showed significant antidepressant-like actions in both models with activity comparable to that of fluoxetine. Yohimbine, an α2-adrenoceptor blocker, inhibited the antidepressant-like actions of GA. In addition, GA (1-10 mg/kg) did not affect locomotor coordination in mice and delayed the onset of convulsions. These findings suggest that GA induces anxiolytic-like effects and has anticonvulsant actions by the possible involvement of the GABAergic system. The antidepressant-like actions of GA may be mediated by noradrenergic neurotransmission.

RESUMEN

Background Fibroblast growth factor 21 (FGF21) is considered an important regulator of lipid and glucose metabolism. However, the role of FGF21 in macronutrient intake and metabolic disease, particularly in pediatric population, still needs further clarification. This study aimed to evaluate the association of rs11665896 in the FGF21 gene with metabolic status and macronutrient intake in a cohort of Mexican children with obesity. Methods Eighty-four lean children and 113 children with obesity, from 8 to 11 years of age, were recruited. FGF21 rs11665896 was genotyped by polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP). Somatometric evaluations, nutrient intake, glucose, lipids, insulin and FGF21 serum levels were measured in the obesity group. Results The T allele of rs11665896 in the FGF21 gene was associated with obesity (odds ratio [OR] = 1.99, 95% confidence interval [CI] = 1.14-3.46; p = 0.0151). Subjects with obesity carrying the TT genotype consumed less lipids and more carbohydrates compared to other genotypes. Circulating FGF21 levels correlated negatively with carbohydrate intake (r = -0.232, p = 0.022) and positively with body weight (r = 0.269, p = 0.007), waist (r = 0.242, p = 0.016) and hip girth (r = 0.204, p = 0.042). FGF21 levels were lower in carriers of at least one T allele. Conclusions Genetic variants in FGF21 could influence metabolic status, food preferences and qualitative changes in nutritional behavior in children.

RESUMEN

ETHNOPHARMACOLOGICAL RELEVANCE: Mexico ranks second in the world for obesity prevalence. In Mexico, obese and overweight subjects commonly seek alternative treatments for weight-loss, including the use of herbal products. AIM OF THE STUDY: The main objective of this study was to evaluate the prevalence of self-medication with herbal products for weight-loss among overweight and obese subjects residing in four states (Guanajuato, San Luis Potosi, State of Mexico, and Mexico City) from central Mexico. In addition, the factors related to self-medication among patients were studied. MATERIALS AND METHODS: A total of 1404 overweight and obese subjects were interviewed. A chi-square test examined associations between socio-demographic and socio-economic information, and self-medication with herbal products for weight-loss. RESULTS: The prevalence of self-medication was 42.9% among the participants who used herbal products for weight-loss. The female gender was the strongest factor (OR: 2.20 (1.75-2.77) associated with self-medication for weight-loss, followed by a low educational level (elementary and middle school) [OR: 1.80 (1.31-2.44)], and a middle-socioeconomic status [OR: 1.75 (1.21-2.52)]. The main herbal products used for weight-loss were based on: i) green tea, Camellia sinensis (12.7% of frequency), ii) aceitilla, Bidens odorata (6.6%), and iii) soybean, Glycine max (5.3%). In addition, 65% of the respondents considered herbal products ineffective for weight-loss after 6 months of use. CONCLUSION: Due to the high incidence of overweight and obesity in Mexico, there is a high prevalence (42.9%) of self-medication using natural products for weight-loss, particularly in women from Central Mexico. This study indicates the important need to educate patients about the harmful effects of consuming these products.

RESUMEN

Self-medication during pregnancy represents a serious threat for mother and child health. The objective of this study was to evaluate the prevalence and the factors associated with self-medication among Mexican women living in the central region of Mexico. This is a descriptive interview-study of 1798 pregnant women or women who were pregnant no more than 3 years ago, when the interview was carried out. Data analysis was carried out with chi-square analysis and odds ratio. The prevalence of self-medication (allopathic drugs, medicinal plants, and other products, including vitamins, food supplements, among others) was 21.9%. The factors associated (p < 0.05) with self-medication were: higher education (college and postgraduate), smoking, and consumption of alcohol. Smoking was the strongest factor (OR: 2.536; 1.46-4.42) associated to self-medication during pregnancy, followed by consumption of alcohol (OR: 2.06; 1.38-3.08), and higher education (OR: 1.607; 1.18-2.19). Medicinal plant consumption was associated with nausea, constipation, migraine, and cold (p < 0.05), whereas he self-medication of allopathy was associated with gastritis and migraine (p < 0.05). Self-medication was influenced mainly by a relative or friend, who recommended the use of herbal medicine/allopathic medication. Two of the most common medicinal plants (arnica and ruda) here informed are reported to induce abortion or toxicity during pregnancy. The findings showed that self-medication (medicinal plants and allopathic medication) is a common practice among pregnant women from central Mexico. Adequate counselling of pregnant women by healthcare professionals about the potential risks of self-medication with herbal medicine and allopathic drugs during pregnancy is strongly warranted.

RESUMEN

The consumption of medicinal plants has notably increased over the past two decades. People consider herbal products as safe because of their natural origin, without taking into consideration whether these plants contain a toxic principle. This represents a serious health problem. A bibliographic search was carried out using published scientific material on native plants from Mexico, Central America, and the Caribbean, which describe the ethnobotanical and toxicological information of medicinal plants empirically considered to be toxic. A total of 216 medicinal plants belonging to 77 families have been reported as toxic. Of these plants, 76 had been studied, and 140 plants lacked studies regarding their toxicological effects. The toxicity of 16 plants species has been reported in clinical cases, particularly in children. From these plants, deaths have been reported with the consumption of Chenopodium ambrosioides, Argemone mexicana, and Thevetia peruviana. In most of the cases, the principle of the plant responsible for the toxicity is unknown. There is limited information about the toxicity of medicinal plants used in Mexico, Central America, and the Caribbean. More toxicological studies are necessary to contribute information about the safe use of the medicinal plants cited in this review.

RESUMEN

ETHNOPHARMACOLOGICAL RELEVANCE: The use of medicinal plants in Mexico has been documented since pre-Hispanic times. Nevertheless, the level of use of medicinal plants by health professionals in Mexico remains to be explored. AIM OF THE STUDY: To evaluate the use, acceptance and prescription of medicinal plants by health professionals in 9 of the states of Mexico. MATERIALS AND METHODS: Direct and indirect interviews, regarding the use and acceptance of medicinal plants, with health professionals (n=1614), including nurses, physicians, pharmacists, and odontologists from nine states in Mexico were performed from January 2015 to July 2016. The interviews were analyzed with the factor the informant consensus (FIC). RESULTS: The information obtained indicated that 46% of those interviewed feel patients should not use medicinal plants as an alternative therapy. Moreover, 54% of health professionals, and 49% of the physicians have used medicinal plants as an alternative therapy for several diseases. Twenty eight percent of health professionals, and 26% of the physicians, have recommended or prescribed medicinal plants to their patients, whereas 73% of health professionals were in agreement with receiving academic information regarding the use and prescription of medicinal plants. A total of 77 plant species used for medicinal purposes, belonging to 40 botanical families were reported by the interviewed. The results of the FIC showed that the categories of diseases of the digestive system (FIC=0.901) and diseases of the respiratory system (FIC=0.898) had the greatest agreement. CONCLUSIONS: This study shows that medicinal plants are used for primary health care in Mexico by health professionals.

RESUMEN

Abstract Bioresorbable linear poly(ether-ester-urethane)s with different hydrophilic characteristics were synthesized from triblock copolymers of poly(ε-caprolactone)-poly(ethylene oxide)-poly(ε-caprolactone) (PCL-PEO) as macrodiols, and L-lysine diisocyanate (LDI) or hexamethylenediisocyanate (HDI) were used as the required diisocyanates. Macrodiols were obtained by ring-opening polymerization (ROP) of ε-caprolactone (CL). Polyurethanes were synthesized by the reaction of the triblock copolymers with LDI or HDI in solution using stannous 2-ethylhexanoate as catalyst. Polyurethane tablets were fabricated and investigated as prospective drug delivery systems. The effect of the PEO content on the polymers' performance as drug carriers was evaluated. It was found that water provoked more swelling and erosion of polymers with higher contents of PEO. The hydrocortisone release profiles were analyzed using the Ritger-Peppas approximation. An anomalous release behaviour (values of n higher than 0.5) was found for most of the analyzed samples.
