En mujeres la FA se asoció con 1.13 veces mayor probabilidad de obesidad, 1.13 de HTA, 2.8 de ERC, 2.9 de EPOC, 4.3 de EVC y 6.5 de IC, en hombres la FA se asoció con 1.05 veces mas probabilidad de HTA, 1.4 de DM, 2.1 de ERC, 2.4 de EPOC, 3 de hipotiroidismo, 4.7 de EVC y 6 de IC. Conclusiones: La FA es una arritmia muy frecuente, con mayor prevalencia en pacientes que acuden a consulta de cardiología, en hombres y mayor edad de presentación en las mujeres. A mayor edad, mayor prevalencia de FA y de comorbilidades, la IC es la condición más frecuente con la que se asoció la FA.
Abstract Objective: To know the epidemiological behavior and associations of AF in Mexican population. Material and methods: 8,686 patients from 38 cardiologists participating in REMECAR were analyzed. They were divided by gender and age, the comorbidities studied were obesity, chronic kidney disease (CKD), high blood pressure (HBP), diabetes mellitus (DM), dyslipidemia, stroke, chronic obstructive pulmonary disease (COPD), hypothyroidism, heart failure (HF) and ischemic heart disease (IHD). Program used: IBM SPSS Statistic. Results: AF was diagnosed in 498 patients (5.7%), with higher prevalence in men (6.1% vs. 5.3%) and older age in women (74.3 ± 12.1 vs. 70.5 + -12.3 years, p<0.0001). In those under 60 years, AF was associated in women with HF, in men with CKD, DM, stroke, hypothyroidism and HF. In women older than 60 years, AF was associated with CKD, dyslipidemia, stroke, chronic COPD and HF, in men with CKD, stroke, COPD, hypothyroidism, HF and IHD. AF in women increase the probability 1.13 for obesity, 1.13 for HBP, 2.8 for CKD, 2.9 for COPD, 4.3 for stroke and 6.5 for HF, in men increase the probability 1.05 for HBP, 1.4 for DM, 2.1 for CKD, 2.4 for COPD, 3.0 for hypothyroidism, 4.7 for stroke and 6.0 for HF. Conclusions: AF is a very common arrhythmia, with a higher prevalence in patients attending the cardiology consultation, in men and with an older age of presentation in women. The older the age, the higher the prevalence of AF and comorbidities, HF is the most frequent condition associated with AF.
ABSTRACT
This work aimed to conduct a laboratory study to evaluate the use of Pseudomonas putida CB-100 and nutrient addition for the removal of PAHs from an aged oil-polluted soil of Veracruz, Mexico. Pseudomonas putida is a biosurfactant-producing bacterium capable of metabolizing polycyclic aromatic hydrocarbons (PAHs), which are toxic compounds with low water solubility, high melting, and boiling points, and low vapor pressure; characteristics that increase as their molecular weight increases and make them more recalcitrant. The methodology consisted in sampling the long-term oil-polluted soil and testing the use of Gamma irradiation (25 kGy) for the sterilization of the soil for abiotic control. We evaluated serological bottles containing 20 g of 35% moist soil (irradiated and non-irradiated) with the following treatments: the addition of nutrients (NH4Cl, NaNO3, KH2PO4, and K2HPO4), an inoculum of P. putida, and both P. putida and nutrients. The parameters assessed were pH, organic matter, humidity, available phosphorus, total nitrogen, cultivable heterotrophic microorganisms, CO2 production, rhamnolipids, surface tension, and the removal of eleven PAHs. The non-irradiated soil added with P. putida was the most efficient in the removal of PAHs; the pattern was: Benzo(a)anthracene > Phenanthrene > Fluoranthene > Benzo(k)fluoranthene > Chrysene > Pyrene > Anthracene > Acenaphthylene > Benzo(b)fluoranthene. In conclusion, P. putida in the non-irradiated soil produced in situ biosurfactants (1.55 mg/kg of rhamnolipids and an 11.9 mN/m decrease in surface tension) and removed PAHs in 10 days.

Background and aims: Dyslipidaemia is a significant risk factor for cardiovascular disease in the Mexican population. This analysis aimed to describe the baseline LDL-c levels of patients presenting to cardiovascular clinics and evaluate the proportion who achieved their risk-based LDL-c goals as recommended by 2021 ESC prevention guidelines. Methods: The REMECAR registry is an observational study of patients attending a specialized cardiovascular clinic for their first visit. The cardiovascular risk was retrospectively determined using the 2021 ESC guideline stratification and the SCORE2 and SCORE-OP. Results: A total of 5443 patients were included in the analysis. Within this population, 55.96% presented as very high, 39.98% as high and 4.06% as moderate to low risk. 63% of the participants were not on any lipid-lowering treatment at entry, while 12.4% were receiving high-intensity statin therapy. Patients presenting with established atherosclerotic cardiovascular disease had a mean LDL-c of 90.9 ± 40.7 mg/dL. Of these, 14.1% were achieving LDL-c levels of 70-55 mg/dL and 19.3% were achieving LDL-c levels <55 mg/dL. In diabetic patients at very high risk, only 25.7% achieved their LDL-c goal. Finally, in patients without another risk factor and very high-risk evaluated by SCORE2 & SCORE-OP, only 14% of patients achieved their LDL-c goals. Conclusions: An important number of patients were not receiving any lipid-lowering therapy. Furthermore, in those who were, a significant portion did not achieve LDL-c recommended thresholds. Our results underline the urgent need to improve the prescription and optimization of lipid-lowering therapy as the current management appears to be insufficient for achieving optimal recommended goals. Identifying key barriers in lipid management is fundamental to establishing better strategies and health system policies to reduce cardiovascular risk.

Current evidence suggests heterogeneity of amyotrophic lateral sclerosis (ALS) among geographic areas and populations. Lower mortality rates have been reported in admixed populations compared to European origin populations. We aimed to describe and compare ALS mortality rates among ethnic groups using a population-based approach in a multiethnic country. Annual mortality cause registers were searched to determine ALS deaths from the National Institute of Statistics and Censuses in Ecuador (INEC) from 1990 to 2016. Mid-year population was considered for each year. The time trend was assessed using a negative binomial regression. Rate ratio statistics were performed to compare the age and sex standardized rates based on the 2010 US population among ethnic groups. Overall, 570 ALS deaths were identified. ALS mortality showed an age-related profile with a peak between 55 and 70 years. After age-sex standardization on the 2010 US population, mortality rate was 0.33 (CI 0.30-0.36) per 100,000. The time trend showed an increase of ALS mortality (p < 0.001). There was no statistical difference in age-sex standardized mortality rates per 100,000 when admixed was compared to white (p = 0.231) and black (p = 0.125). Differences reached statistical significance between admixed and other ethnics (p = 0.015). Our population-based study supports the hypothesis that ALS occurrence is lower in predominant admixed populations from Latin America compared to European and Northern American populations. Further studies are needed to clarify the role of ancestral origin in ALS susceptibility.

BACKGROUND: Epilepsy is felt to be a stigmatizing condition. Stigma has been considered one of the major factors contributing to the burden of epilepsy and to the treatment gap. Stigma has a negative effect on the management of people with epilepsy (PWE). Furthermore, lack of information and inappropriate beliefs are still the factors that most contribute to stigma and discrimination. In this study, we assessed the level of perceived stigma in urban and rural areas and we report their association with in antiepileptic drug (AED) use, effects on seeking medical care, and stigma-associated factors. METHODS: A cross-sectional study in urban and rural areas in Ecuador from January 2015 until May 2016. People with a confirmed diagnosis of epilepsy were included using three sources of information. The survey was implemented through a questionnaire to determine perceived stigma and evaluate the factors associated. The perceived stigma was measured using the revised Jacoby's stigma scale to detect differences in levels of stigmatization. Access to treatment was evaluated through self-report of AED use, and attainment of medical care and stigma-associated factors were assessed. Furthermore, a multivariate analysis adjusted for possible confounders was performed using stigma as the outcome variable. RESULTS: A total of 243 PWE were interviewed, 65.8% reported feeling stigmatized and 39.1% reported a high stigmatized level. We found a significant difference in high stigma perception in the urban area compared to the rural area. However, the lack of use of AEDs was significantly higher in the rural areas. No significant correlation was found between use of AEDs and the levels of perceived stigma. PWE who did not talk about their condition and those who did not feel well informed about their epilepsy had significantly higher perceived stigma levels. Additionally, the multivariate analysis demonstrated that area, educational level, type of seizure, talk about epilepsy, and information were associated with perceived stigma. CONCLUSION: The stigma perception was relevant in all PWE. We found a higher stigma level perception in the urban compared to rural area. Moreover, the lack of treatment was a serious problem mainly in rural areas. Even though we did not find that perceived stigma was associated with AED use, our study pointed out the influence of educational level and information related to stigmatization. Consequently, a coordinated effort to reduce stigma should include strategies focused on PWE education and information about their condition.

Bagasse of Agave tequilana (BAT) is the residual lignocellulosic waste that remains from tequila production. In this study we characterized the chemical composition of BAT, which was further saccharified and fermented to produce ethanol. BAT was constituted by cellulose (42%), hemicellulose (20%), lignin (15%), and other (23%). Saccharification of BAT was carried out at 147 °C with 2% sulfuric acid for 15 min, yielding 25.8 g/l of fermentable sugars, corresponding to 36.1% of saccharificable material (cellulose and hemicellulose contents, w/w). The remaining lignocellulosic material was further hydrolyzed by commercial enzymes, ~8.2% of BAT load was incubated for 72 h at 40 °C rendering 41 g/l of fermentable sugars corresponding to 73.6% of the saccharificable material (w/w). Mathematic surface response analysis of the acid and enzymatic BAT hydrolysis was used for process optimization. The results showed a satisfactory correlation (R (2) = 0.90) between the obtained and predicted responses. The native yeast Pichia caribbica UM-5 was used to ferment sugar liquors from both acid and enzymatic hydrolysis to ethanol yielding 50 and 87%, respectively. The final optimized process generated 8.99 g ethanol/50 g of BAT, corresponding to an overall 56.75% of theoretical ethanol (w/w). Thus, BAT may be employed as a lignocellulosic raw material for bioethanol production and can contribute to BAT residue elimination from environment.
