Determinants of Vitamin D Status in Healthy Young Adults from Mexico City.

BACKGROUND AND AIMS: Vitamin D deficiency is a global health problem. The determinants of this deficiency have not been evaluated in developing countries such as Mexico. Thus, this study aimed to determine vitamin D intake and sun exposure and its relationship with plasma concentrations of 25-hydroxyvitamin D -25(OH)D- in young adults from Mexico City. METHODS: One hundred fifty five urban adult subjects were enrolled during 2017 and 2018. Sociodemographic, anthropometric, and clinical data, vitamin D intake, and sun exposure habits were collected. Plasma concentrations of 25(OH)D were also determined. RESULTS: The proportion of vitamin D deficiency was significantly higher in women than in men (65.7 vs. 43.4%, p = 0.012). The overall median dietary vitamin D intake was 112 IU/d (less than 20% of the recommended daily intake; RDI). 25-hydroxyvitamin D correlated directly with vitamin D intake, sun exposure score, waist-to-hip ratio, and age; an inverse significant association was found with body fat percentage. A multiple regression analysis was performed; simultaneous and significant (p <0.01) effects of sun exposure score, dietary vitamin D, the season of the year (spring-summer vs. fall-winter), and age were observed on 25(OH)D levels. CONCLUSION: High rates of vitamin D deficiency and insufficiency were observed in young adults from Mexico City. According to the RDI of this vitamin, its consumption, assessed by a 24 h multi-step nutritional questionnaire, was significantly low. A linear multiple regression model identified several predictors of plasma 25(OH)D concentrations. This multiple regression model was statistically validated.

The marginalization index and its association with selected services within the comprehensive care offered to breast cancer patients.

PURPOSE: There is little information on the supportive care offered to breast cancer patients. We investigated the association between the marginalization index and selected services offered by health professionals. METHODS: We used data from a cross-sectional parent study performed in Mexico from 2007 to 2009. We analyzed data from 832 women between 35 and 69 years of age with a histopathological diagnosis of breast cancer. This study was performed in hospitals in 5 states. We used frequencies, measures of central tendency, and logistic regression. We used the svy package of STATA statistical software v17. RESULTS: Overall, 15.6% of the study population reported that health professionals offered them selected services. The offer of two or more selected services was greater among women living in states with a very high marginalization index (21.8%) than among those living in states with a very low marginalization index (13.8%). Among women living in states with high marginalization, the odds of receiving a selected service offer were 2.03 times higher than those living in states with low marginalization (Odds ratio (OR) = 2.03, 95% CI 1.08-3.83). For women in the highest tertile of the asset index, the odds of receiving a selected service offer were 2.7 times greater than the odds for women in the lowest tertile (OR = 2.66, 95% CI 1.03-6.88). CONCLUSION: The prevalence of comprehensive care offered to breast cancer patients is low in Mexico and varies according to the marginalization index and the asset index.

Anaemia in adolescent women: A priority for the nutrition agenda in Mexico. A comparison of data from the ENSANUT 2012 and 2018-2019 surveys.

The risk of anaemia in adolescence increases due to accelerated growth. This study aims to: (1) estimate the prevalence of anaemia in 2012 and 2018-2019 (Encuesta Nacional de Salud y Nutricion - ENSANUT [n = 5841 in 2012 and n = 2380 in 2018-2019]) in non-pregnant, Mexican adolescent women aged 12-19 years, and the changes in prevalence over this period according to sociodemographic, health and nutrition characteristics; (2) estimate the associations between anaemia and sociodemographic, health and nutrition characteristics in each year and overall, in non-pregnant Mexican adolescent women. Anaemia was defined as capillary haemoglobin <12 g/dL. The distribution of characteristics and their changes between 2012 and 2018-2019 were described. The covariate-adjusted prevalence of anaemia in 2012 and 2018-2019 and the changes over that period were estimated from a multiple log-binomial regression model and the factors associated with anaemia were assessed in each survey year and in both years combined. The prevalence of anaemia was 7.7% in 2012 and 13.1% in 2018-2019 (69% increase, Prevalence Ratio: PR = 1.69; 95%CI: 1.35, 2.13). The covariate-adjusted prevalence of anaemia increased from 6.9% to 10.5% in the overall population (PR = 1.53, 95%CI: 1.19, 1.96), and increased considerably in the age group 12-14 years (PR = 1.94, 95%CI: 1.36, 2.75), and in the northern region (PR = 3.68, 95%CI: 2.55, 5.32). Those receiving iron supplements or school breakfasts did not register a significant increase. A higher household wellbeing status and older age were associated with a lower prevalence of anaemia. Anaemia in non-pregnant adolescent women continues to be a public health problem. To improve the development and health of adolescent women in Mexico and to pave the way to a healthy pregnancy for the next generation, the causes of anaemia should be identified.

Insurance status and access to cervical cancer treatment in a specialized cancer center in Mexico.

To describe access to complete treatment in women with cervical cancer and state-sponsored insurance versus no insurance. We conducted a retrospective observational study. The source population consisted of women treated for cervical cancer from January 2000 to December 2015 in a tertiary care hospital. We included 411 women with state-sponsored insurance and 400 without insurance. We defined access to cervical cancer treatment as complete treatment (according NCCN/ESMO (National Comprehensive Cancer Network/European Society for Medical Oncology) standards) and timely initiation of treatment (less than 4 weeks). Clinical and sociodemographic characteristics were described and analyzed with logistic regression using complete treatment as the main outcome. A total of 811 subjects were included, the median age was 46 (IQR (Interquartile range) 42-50) years. Most of them were married (36.1%), unemployed (50.4%), and had completed primary school (44.0%). The most common clinical stages at diagnosis were II (38.2%) and III (24.7%). In the adjusted regression model, being married (OR (odds ratio): 4.3, 95% CI (confidence interval): 1.74-10.61) and having paid employment (OR: 2.79, 95% CI: 1.59-4.90) or state-sponsored insurance (OR: 1.54, 95% CI: 1.04-2.26) were positively associated with the possibility of having a complete treatment. Women with insurance were likely to be younger and receive timely treatment compared with uninsured women. Complete treatment was associated to insurance status and advanced stages of cervical cancer. State-sponsored insurance improves access to complete treatment. Government policies are needed to avoid social and economic inequity and provide better management of cervical cancer in our country.

'It is in our hands-Why wait until you are sick?': Perceptions about diabetes prevention of Latina mothers in Mexico and the United States.

AIMS: This study aimed to understand the perceptions driving type 2 diabetes mellitus prevention and management behaviours of Mexican and Latina mothers in Mexico and the United States. METHODS: Low-income Mexican mothers in San Luis Potosí, Mexico and Latina mothers in Illinois, United States, were recruited by the Holistic Obesity Prevention Study (HOPS). Verbatim transcripts of the semistructured interviews conducted in Spanish (n = 24) and English (n = 1) were analysed using the Health Belief Model (HBM) framework. RESULTS: Of the 25 participants, 22 (88%) indicated 'knowing someone with diabetes'-specifically a father (n = 8), mother (n = 6) or grandparent (n = 7). Using the HBM, themes showed that mothers perceived: that Type 2 diabetes can happen to anyone, are attributable to genetic predisposition and may be driven by strong emotions (perceived susceptibility). Type 2 diabetes introduces severe comorbidities and emotional difficulties for people and their families (perceived severity). Adopting a healthier diet, exercising and staying in good spirits were recognized as benefits of Type 2 diabetes prevention (perceived benefits). The costs of food, challenges of exercising, dieting, modifying habits and time limitations were recognized as perceived costs. Cues to action included doctors' recommendations (external) and fear (internal). Mothers acknowledged they could live a healthy life by controlling their weight, exercising, adhering to treatments/medications and having the determination to carry-on (self-efficacy). CONCLUSIONS: Mothers sought to prevent Type 2 diabetes and live healthy lives, particularly, after receiving a diagnosis of gestational diabetes or when learning about their children's risks for Type 2 diabetes but perceived significant barriers to Type 2 diabetes prevention.

"We All Have a Job to Do in This World, It's up to Us": Farmworker and Farmer Mental Health in a Rural US-Mexico Border Region.

Improving mental health outcomes for agricultural populations is dependent on understanding the unique farming related stressors in context of the local culture and community. This study was designed to assess the prevalence of stressors and mental health risks among farmers and farmworkers in a rural, medically underserved US-Mexico border region. Of 135 study respondents, 55.6% (n = 18) farmers had clinical depression symptomatology based on the Center for Epidemiologic Studies depression screening scale (CES-D) and 40.2% (n = 117) farmworkers had stress levels that pose significant mental health risks based on the Migrant Farmworker Stress Inventory. Farmworker females were 2.3 times more likely to have a score of clinical concern. Results provide an understanding of the distinct sources of stress for both farmers and farmworkers and the mental health challenges across the industry. With an understanding that suicide is the third leading cause of injury death in Imperial County and depression associated with an increased risk of suicidality, the agricultural workforce in Imperial County is particularly vulnerable. Local farm organizations, employers, and community organizations can help increase mental health access, acceptability, and availability to achieve greater safety and health in the region's largest workforce.

Self-Medication Practice in Mexico.

Objective To determine the prevalence and features of self-medication (SM) in Mexican populations. Data Sources An electronic bibliographic search was carried out from databases and indexing services including Scopus, PubMed, International Pharmaceutical Abstracts (Clarivate Analytics), Embase, Web of Science and Google Scholar addressing SM practice in Mexican populations, SM with allopathic or conventional medicines (CM) or complementary and alternative medicine (CAM), and features of SM (diseases-related, factors-associated, and drugs). Study Selection A total of 33 studies addressing SM practice in Mexican populations. SM with allopathic or CM and/or CAM, and features of SM (diseases-related, factors-associated, and drugs) were included. Data Extraction Two independent reviewers evaluated the titles and abstracts. After that, eligible studies were fully assessed. Quality evaluation was realized by the Mix Methods Appraisal Tool. Data Synthesis SM prevalence ranged from 6.1 to 100%. SM prevalence was 42.3% with CM and 30.7% with CAM. Respiratory and gastrointestinal affectations such as disorders or injuries were the main conditions for which SM was realized. The main reasons for practicing SM were prior experience and less costly. Antibiotics, anti-inflammatory drugs, and antidiarrheal were the main drugs used as SM. Chamomile (Matricaria chamomilla), peppermint (Mentha piperita), and gordolobo (Verbascum thapsus) infusions were the plant-derived alternative medications mainly used. CMs were obtained mainly through pharmacies and home/family. SM was mainly suggested by relatives, pharmacists, and own decision. Conclusion SM was a common practice in the Mexican population, and it has some similar characteristics to other reports worldwide.

A cross-sectional study of factors associated with COVID-19 testing among people who inject drugs: missed opportunities for reaching those most at risk.

BACKGROUND: People who inject drugs (PWID) are vulnerable to SARS-CoV-2 infection. We examined correlates of COVID-19 testing among PWID in the U.S.-Mexico border region and described encounters with services representing potential opportunities (i.e., 'touchpoints') where COVID-19 testing could have been offered. METHODS: Between October, 2020 and September, 2021, participants aged ≥18 years from San Diego, California, USA and Tijuana, Baja California, Mexico who injected drugs within the last month completed surveys and SARS-CoV-2, HIV, and HCV serologic testing. Logistic regression identified factors associated with COVID-19 testing including potential touchpoints, comorbidities and COVID-19 related misinformation and disinformation. RESULTS: Of 583 PWID, 30.5% previously had a COVID-19 test. Of 172 PWID who tested SARS-CoV-2 seropositive (30.1%), 50.3% encountered at least one touchpoint where COVID-19 testing could have been offered within the prior six months. Factors independently associated with at least two fold higher odds of COVID-19 testing were living in San Diego, recent incarceration, receiving substance use treatment, and experiencing ≥1 chronic health condition. Homelessness, having received ≥1 dose of COVID-19 vaccine, and having a HIV or HCV test since the COVID-19 epidemic began were also independently associated with having had a prior COVID-19 test. CONCLUSION: We identified several factors independently associated with COVID-19 testing and multiple touchpoints where COVID-19 testing could be scaled up for PWID, such as SUD treatment programs and syringe service programs. Integrated health services are needed to improve access to rapid, free COVID-19 testing in this vulnerable population.

Structural violence and the need for compassionate use of methadone in Mexico.

BACKGROUND: Epidemiological data from Mexico have documented an increase in heroin use in the last decade. However, there is no comprehensive care strategy for heroin users, especially those who have been accused of a crime. The objective of this study was to describe the heroin and methadone use of intravenous heroin users of both sexes who have been in jail, to offer evidence for the formulation of health policy. METHODS: This study used an ethnographic approach, with open-ended interviews carried out from 2014 to the present. Heroin users of both sexes attending a private methadone clinic in Mexico City were invited to participate. The sample was non-probabilistic. All interviews were audiotaped and transcribed, and narratives were analyzed using thematic analysis. RESULTS: Participants in this study were 33 users of heroin, two of them women, who had been in prison. They ranged in age from 33 to 62 years, had used heroin for a period of 13-30 years, and were from three states: Michoacan, Oaxaca, and Mexico City. Three principal categories of analysis were structured: 1. Pilgrimage for help (dynamics of the drama of suffering, pain, and time through health care spaces); 2) methadone use as self-care; and 3) accessibility to methadone treatment. The impossibility of access to methadone treatment is a condition which motivates users in their journey. The dynamics of methadone use are interpreted as a form of self-care and care to avoid substance use. Reducing the psychological, physical, and harmful effects of the substance allows them to perform daily activities. The inability to access treatment leads to a significant effect on users who experience structural violence. CONCLUSION: Compassionate methadone treatment and holistic attention should be considered as a way to meet patients' needs and mitigate their suffering, based on public health policy that allows for human rights-based care.

[PRIISMA Project: Transformation into a more preventive, resilient, comprehensive, innovative, sustainable, modern and accessible IMSS]. / Proyecto PRIISMA: transformación hacia un IMSS más preventivo, resiliente, integral, innovador, sostenible, moderno y accesible.

Two years after the onset of the COVID-19 pandemic, the Mexican Institute for Social Security (IMSS, according to its initials in Spanish) rethought new projects focused on the new needs of the population and social security organizations and institutions. The Institute, as a cornerstone in the search for the wellbeing of Mexicans, aligned with the National Development Plan and the Strategic Health for Wellbeing Program, sought to direct its transformation towards a preventive, resilient, comprehensive, innovative, sustainable, modern and accessible IMSS. For this reason, the Medical Services Director designed the PRIISMA Project, as the one that over the next three years could make possible to innovate and improve its medical care processes, starting with the recovery of medical services and identifying those groups of beneficiaries who experience the most vulnerable circumstances. The PRIISMA project consisted of five sub-projects: 1. Vulnerable groups; 2. Efficient and effective care; 3. Prevent IMSS plus; 4 IMSS University and 5. Recovery of medical services. The strategies of each project seek to improve medical care for all IMSS beneficiaries and users with a human rights perspective and by priority groups; the goal is reducing the gaps in access to health care, leaving no one behind and leaving no one out; and to surpass the goals for medical services provided before the pandemic. This document provides an overview of strategies and progress of the PRIISMA sub-projects achieved during 2022.

Después de dos años del inicio de la pandemia por COVID-19, el Instituto Mexicano del Seguro Social (IMSS) se replanteó nuevos proyectos enfocados a las nuevas necesidades de la población y de las organizaciones e instituciones de salud y seguridad social. El Instituto, como piedra angular de la búsqueda del bienestar de las mexicanas y mexicanos, alineado al Plan Nacional de Desarrollo y al Programa Estratégico de Salud para el Bienestar, buscó dirigir su transformación hacia un IMSS más preventivo, resiliente, integral, innovador, sostenible, moderno y accesible. Por ello la Dirección de Prestaciones Médicas diseñó el Proyecto PRIISMA, el cual durante los próximos tres años permitirá innovar y mejorar sus procesos de atención médica, comenzando con la recuperación de los servicios médicos y la identificación de aquellos grupos de derechohabientes que experimentan mayores circunstancias en situación de vulnerabilidad. El Proyecto PRIISMA está constituido por cinco subproyectos: 1) grupos en situación de vulnerabilidad; 2) atención eficiente y eficaz; 3) PrevenIMSS más; 4) Universidad IMSS, y 5) recuperación de servicios médicos. Las estrategias de cada proyecto buscan mejorar la atención médica de todos los derechohabientes y usuarios del IMSS con perspectiva de derechos humanos y por grupos prioritarios; se trata de reducir las brechas para el acceso a la salud sin dejar a nadie atrás y a nadie fuera; además, con ellas se busca superar las metas de atención de servicios médicos otorgados antes de la pandemia. El presente documento da a conocer los porqués, las estrategias y los avances de los subproyectos PRIISMA logrados durante el 2022.

Urinary fluoride and micronutrients intake in children from San Luis Potosi, Mexico.

To assess the relationship between urinary fluoride and micronutrients intake we recruited 121 schoolchildren from San Luis Potosí. We evaluated fluoride concentrations in drinking water and urine with the ion-selective electrode method and estimated calcium, magnesium, and phosphorus intakes with a validated consumption frequency questionnaire. About 72% of the population used tap water for drinking and cooking. Fluoride concentrations were 2.36 ± 0.02 mg/L in tap water, 0.14 ± 0.04 mg/L in bottled water and 2.05 ± 0.62 mg/L in urine. Urinary fluoride was higher in children with a consumption <50% of the Recommended Daily Intake (RDI) of calcium (2.20 v/s 1.96 mg/L; p < 0.05), <50% RDI of magnesium (2.58 v/s 1.96 and 1.90 mg/L; p < 0.05) and >150% RDI of phosphorus (2.43 v/s 1.82 mg/L; p < 0.05). These data indicated that fluoride concentration in tap water is higher than bottled water and estimated micronutrients intake is related to urinary fluoride.

Use of herbal medicine for diabetes mellitus in adults from the central-western region of Mexico.

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.

Prenatal PM2.5 exposure in the second and third trimesters predicts neurocognitive performance at age 9-10 years: A cohort study of Mexico City children.

INTRODUCTION: Prenatal exposure to fine particulate matter air pollution (PM2.5) is an important, under-studied risk factor for neurodevelopmental dysfunction. We describe the relationships between prenatal PM2.5 exposure and vigilance and inhibitory control, executive functions related to multiple health outcomes in Mexico City children. METHODS: We studied 320 children enrolled in Programming Research in Obesity, GRowth, Environment and Social Stressors, a longitudinal birth cohort study in Mexico City. We used a spatio-temporal model to estimate daily prenatal PM2.5 exposure at each participant's residential address. At age 9-10 years, children performed three Go/No-Go tasks, which measure vigilance and inhibitory control ability. We used Latent class analysis (LCA) to classify performance into subgroups that reflected neurocognitive performance and applied multivariate regression and distributed lag regression modeling (DLM) to test overall and time-dependent associations between prenatal PM2.5 exposure and Go/No-Go performance. RESULTS: LCA detected two Go/No-Go phenotypes: high performers (Class 1) and low performers (Class 2). Predicting odds of Class 1 vs Class 2 membership based on prenatal PM2.5 exposure timing, logistic regression modeling showed that average prenatal PM2.5 exposure in the second and third trimesters correlated with increased odds of membership in low-performance Class 2 (OR = 1.59 (1.16, 2.17), p = 0.004). Additionally, DLM analysis identified a critical window consisting of gestational days 103-268 (second and third trimesters) in which prenatal PM2.5 exposure predicted poorer Go/No-Go performance. DISCUSSION: Increased prenatal PM2.5 exposure predicted decreased vigilance and inhibitory control at age 9-10 years. These findings highlight the second and third trimesters of gestation as critical windows of PM2.5 exposure for the development of vigilance and inhibitory control in preadolescent children. Because childhood development of vigilance and inhibitory control informs behavior, academic performance, and self-regulation into adulthood, these results may help to describe the relationship of prenatal PM2.5 exposure to long-term health and psychosocial outcomes. The integrative methodology of this study also contributes to a shift towards more holistic analysis.

Nutritional status of iron, vitamin B12, vitamin A and anemia in Mexican children: results from the Ensanut 2018-19.

OBJECTIVE: To describe the current status of micronutrient deficiencies (MD) and anemia in Mexican children. MATERIALS AND METHODS: Serum data from 1 382 pre-school-age chil-dren (1-4 years) and 3 590 school-age children (5-11 years) Ensanut 2018-19 participants were analyzed. Iron deficiency (ID), vitamin B12 deficiency (B12D), vitamin A depletion (VADp), and anemia were identified. Logistic regression models were used to identify associations between socio-demographic characteristics of children and MD. RESULTS: Anemia was present in 28.9 and 19.2% of the children aged 1-4 and 5-11, respectively; in ID 10 and 5.1%; B12D, in 5.1 and 4.8%, and VADp, in 4.7 and 4.3%. 18.5% of the preschool-age children and 13% of the school-age children had at least one MD associated to anemia. CONCLUSIONS: MD and anemia affect the younger children in larger proportion. Fortification and supplementation programs should be reinforced to avoid the long-term consequences of MD.

Mental health and diabetes self-management: assessing stakeholder perspectives from health centers in Northern Mexico.

BACKGROUND: People living with diabetes have an increased risk of developing mental health issues. Mexico has observed a high prevalence of people living with diabetes suffering from mental health issues, such as anxiety and depression. Self-management programs have demonstrated promise in helping participants address and prevent not only physiological health complications but mental health issues as well. This qualitative study aimed to understand the mental health benefits of a diabetes self-management intervention for health centers in Northern Mexico and opportunities for improvement through assessing stakeholder perspectives. METHODS: Trained research staff used a semi-structured questionnaire guide to conduct all interviews and focus groups from February-May 2018. Individual interviews (n = 16) were conducted face-to-face at four health center sites among all health center directors and key staff located throughout the state of Sonora. One focus group (n = 41) was conducted at each of the four health centers among intervention participants. Directed content analysis was used to establish themes by understanding relationships, identifying similar experiences, and determining patterns across datasets. RESULTS: In total 57 health center directors, health center staff, and intervention participants were involved in the interviews and focus groups across the four health centers. Overall the analysis identified four themes throughout the data, two were categorized as benefits and two as improvements. The primary themes for participant benefits were an increase in self-efficacy and social support to manage their chronic conditions. These were evident from not only participant perspectives, but health staff observations. Conversely, increased family involvement, and increased mental health integration and services within diabetes care were identified themes for opportunities to improve the intervention to be more inclusive and holistic. CONCLUSION: All stakeholders observed the benefits for intervention participants and opportunities for more inclusivity of the family and integration as well as an increase in mental health services. The themes identified demonstrated a need to more proactively enhance and utilize diabetes self-management as a means to improve mental health outcomes among people living with diabetes in Mexico. This is an opportunity to employ a more comprehensive approach to diabetes self-management, and integrate mental health services into overall diabetes care.

Self-treatment and adverse reactions with herbal products for treating symptoms associated with anxiety and depression in adults from the central-western region of Mexico during the Covid-19 pandemic.

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.

[Food insecurity and its association with obesity and cardiometabolic risks in Mexican women]. / Inseguridad alimentaria y su asociación con la obesidad y los riesgos cardiometabólicos en mujeres mexicanas.

INTRODUCTION: Objective: we conducted a systematic review of the main scientific evidence that associates food insecurity with a higher frequency of obesity and cardiometabolic risks in Mexican women. Design: a systematic review. Data sources: MEDLINE, Embase, CINAHL Plus, Web of Science, CAB Abstracts and PAIS Index. Selection criteria: articles that met the journal quality criteria and integrated food status with health insecurity, in which the situation of vulnerability in the current statistics for cardiometabolic diseases and risks that are associated with food insecurity was shown in women and their homes. Data analysis: relevance and quality of the results regarding food security, the presence of overweight and obesity, and socio-environmental indicators in women. Results: households headed by women who are at higher risk of having some degree of food insecurity or food assistance associated with the presence of obesity and overweight (RR = 1.28 to 2.97; 95 % CI: 1.08-1.44 to 1.52-6.14) as well as the development of cardiometabolic diseases such as diabetes mellitus (with a history of pregnancy as risk factor for developing diabetes and hypertension) presenting premature labor, shorter stature in the adult stage, a deficiency in micronutrients such as iron and antioxidant vitamins. Conclusion: the evidence found shows an association of food insecurity as found in women and their homes with a greater risk of being overweight and obese, as well as the development of a cardiometabolic disease (diabetes, hypertension), in addition to anemia and vitamin deficiency.

INTRODUCCIÓN: Objetivo: realizar una revisión de la principal evidencia científica que asocie la inseguridad alimentaria con una mayor frecuencia de obesidad y riesgos cardiometabólicos en mujeres mexicanas. Diseño: revisión sistemática. Fuentes de datos: MEDLINE, Embase, CINAHL Plus, Web of Science, CAB Abstracts y PAIS Index. Selección de estudios: artículos que reunieran los criterios de calidad de las revistas e integraran la situación de inseguridad alimentaria y salud, en los que se viera la situación de vulnerabilidad en las estadísticas actuales de enfermedades y riesgos cardiometabólicos asociados con la situación de inseguridad alimentaria en mujeres y sus hogares. Extracción de datos: relevancia y calidad de los resultados respecto a la seguridad alimentaria, la presencia de sobrepeso y obesidad, e indicadores socioambientales en las mujeres. Resultados: los hogares encabezados por mujeres presentaron mayor riesgo de tener algún grado de inseguridad alimentaria o carencia alimentaria, asociándose esta con la presencia de obesidad y sobrepeso (RR = 1,28 a 2,97; IC 95 %: 1,08-1,44 a 1,52-6,14) así como con el desarrollo de enfermedades cardiometabólicas como la diabetes mellitus (siendo el embarazo, como antecedente, un factor de riesgo para desarrollar diabetes e hipertensión), presentar partos prematuros, tener menor estatura en la etapa adulta, una deficiencia de micronutrimentos como el hierro y de vitaminas antioxidantes. Conclusiones: la evidencia encontrada muestra una asociación de la inseguridad alimentaria encontrada en las mujeres y sus hogares con una mayor probabilidad de presentar sobrepeso y obesidad, así como el desarrollo de una enfermedad de índole cardiometabólica (diabetes, hipertensión), además de anemia y deficiencia de vitaminas.

Association of airborne particulate matter with pollen, fungal spores, and allergic symptoms in an arid urbanized area.

Studies focused on the seasonal distribution of pollen and spores in semiarid cities are scarce. At these sites, climate change potentiates the emission and transport of fine (PM10) to ultrafine particles (PM2.5), easily attached to pollen surfaces, causing allergen's release. This study examines the potential correlation of seasonal variations of pollen, fungal spores, PM10, and meteorological parameters with allergic reactions of 150 people living in a Sonoran desert city. We collected PM10, airborne pollen, and spores during a year. We also studied topsoil and road dust samples as potential PM-emission sources. We obtained dust-mineralogy, chemistry, and particle size attached to pollen by X-ray diffraction and scanning electron microscope. Results show that seasonal high PM-loading in the urban atmosphere coincides with aeroallergens promoting micro- to nanoparticles' attachment to pollen's surface. A collapsed membrane was observed in several samples after individual grains show the following maximum wall coverage: Poaceae 28%, Asteraceae 40%, Chenopodiaceae-Amaranthacea 29%, Fabaceae 18%. Most of the particles covering pollen's surface have a geogenic origin mixed with metals linked to traffic (bromide, chlorine, and antimony). Mineralogical, granulometric analysis, and main wind-direction show that two local soil-types are the main contributors to PM. A high frequency of positive sensitization to pollen with high particle loading was detected. These results suggest that climate-driven dust emissions may alter pollen and spore surfaces' physicochemical characteristics with the further consequences in their allergenic potential.
