[Factors associated with caregiver burden in primary caregivers of older adults with type2 diabetes]. / Factores asociados a la sobrecarga del cuidador en cuidadores primarios de personas adultas mayores con diabetes tipo2.

OBJECTIVE: To characterize the profile of the informal primary caregiver (IPC) of adult patients with type2 diabetes (T2D) and the possible factors associated with caregiver collapse (CC). DESIGN: Observational, descriptive, cross-sectional and analytical study. SITE: Ambulatory Care Medical Unit. PARTICIPANTS: Mexican CPIs of adult patients with T2D. MAIN MEASUREMENTS: Data were collected through a prolective design using the Zarit scale and a structured survey on sociodemographic factors. A descriptive statistical analysis and univariate and multivariate logistic regression models were performed. RESULTS: The CPI profile is assumed by: women, people aged 36-58, daughters, people with a secondary and high school educational level, married, Catholic, with income <8,900 Mexican pesos, own home, inhabited by a maximum of 5 inhabitants, with support networks, who have dedicated >5years to the care of their patient, without training and with chronic diseases. The risk factors that increase the risk of CC are: being a woman (OR=11.03; 95%CI: 1.49-81.95), having a history of more than 5years of having assumed the role of caregiver (OR=2, 65; 95%CI: 1.07-6.55), living in one's own house (OR=3.03; 95%CI: 1.04-8.82), with 6 or more inhabitants (OR=2.41; 95%CI: 1.08-5.38). The support of other family members and/or friends was associated as a protective factor (OR=0.15; 95%CI: 0.07-0.33). CONCLUSIONS: Prevention programs are required to avoid CC and complications, as well as interventions to improve the quality of life of the CPI and patients in care, incorporating strategies to generate and/or increase their family and social support networks.

Need for public health policies in the elderly population: indicators of aging in a Social Security Institute in Mexico.

INTRODUCTION: An integral diagnosis of population contemplates within its components the population demographic analysis that is indispensable in the formulation of public policies. Population policy has a clearly transversal nature, since all actions in the economic, social, political, cultural, geographical, and obviously, demographic fields, have direct or indirect repercussions on it. OBJECTIVES: To determine the population dynamics and the global growth of the older adult population (OAP) of 60 years and more. MATERIALS AND METHODS: Cross-sectional, retrospective study. The information was obtained from the statistical yearbooks of the institute of security and social services of state workers, Mexico (1999-2015). Several demographic ageing indicators were analyzed. RESULTS: There was a constant increase in percentage points in the proportion of OAP, index of ageing, demographic dependency ratio of old age, global index of dependence, index of dependence of old people, and index of the active population structure (6, 19.2, 15.5, 8.5, 8.2 and 31.2%, respectively). The indicator global index of dependence and masculinity showed a decrease (0.6 and 3.1%, respectively). CONCLUSIONS: Our data provide evidence that suggests modifying and generating public policies according to OAP.

New model for diabetes primary health care based on patient empowerment and the right to preventive health: the MIDE program.

OBJECTIVE: To evaluate Mexico's national Integrated Management of Diabetes in Stages (Manejo Integral de la Diabetes por Etapas, MIDE) program using three types of indicators: process, structure, and impact. METHODS: A cross-sectional study was conducted using data for 97 452 people with diabetes (PWD) who participated in the MIDE patient empowerment program (PEP) at "MIDE modules" (standardized diabetes health care units) at Mexico's Institute for Social Security and Services for State Workers (Instituto de Seguridad y Servicios Sociales de los Trabajadores del Estado, ISSSTE) hospital clinics and family medical clinics nationwide between 2007 and 2014. The program promotes diabetes patient empowerment and self-care through outpatient consultations with a multidisciplinary health care team supported by continuous training. Baseline data were compared with results post-program for the following indicators: process (metabolic control (MetC), based on glycated hemoglobin (HbA1c), triglyceride (TG), and total cholesterol (TC) levels); structure (number of MIDE modules installed at ISSSTE clinics and number of patients/health personnel accredited as diabetes experts/awarded diplomas); and impact (average number of patient illness days (IDs) and hospitalization episodes (HEs) per PWD over a 12-month period). RESULTS: Over the seven-year study period, the proportion of patients with MetC (HbA1c < 7.0%, TG < 150 mg/dL, and TC < 200 mg/dL) increased significantly (from 35.4% to 60% (with a peak level of 62% in 2013); P < 0.001); average HbA1c, triglycerides, and total cholesterol per PWD dropped by 25%, 31%, and 11% respectively; average number of IDs and HEs per PWD over a 12-month period dropped by 38% and 41% respectively; a total of 140 MIDE modules were installed at ISSSTE clinics; and a total of 1 117 diplomas were awarded to 826 health professionals, and 2 613 PWD were accredited as "patient experts in diabetes." CONCLUSIONS: The MIDE PEP is feasible, usable, and acceptable to PWD. The program improves MetC; reduces the frequency of IDs and HEs; and facilitates patient participation, the involvement of health personnel, and shared decision-making.

[Evaluation of the FD-66 Scale as a tool for predicting treatment adherence in patients with chronic non-communicable diseasesAvaliação da escala EFD-66 como instrumento para predizer a adesão ao tratamento em pacientes com doenças crônicas não transmissíveis]. / Evaluación de la Escala EFD-66 como herramienta para predecir la adherencia al tratamiento en pacientes con enfermedades crónicas no transmisibles.

OBJECTIVE: The objectives of this study are to validate the construct of the stages of grief scale (FD-66) as an instrument for measuring the stages of grief and to evaluate its usefulness in discriminating among patients with chronic non-communicable diseases in terms of adherence to the pharmacological treatment prescribed. METHODS: A cross-sectional study was conducted from April to October 2015 to determine the association between the stages of grief and treatment adherence. Data were collected using a prolective design. Three instruments were applied: a sociodemographic document, the FD-66 scale, and the Morisky-Green questionnaire. Patients with a history of CNCDs were recruited from the Gustavo A. Madero Family Medicine Clinic in Mexico City. The data were analyzed using the appropriate statistical tests. RESULTS: A total of 165 patients were included. It was observed that high scores on the subscales of denial (odds ratio [OR]: 1.124; confidence interval of 95% [CI95%]: 1.066-1.186; P < 0,001); anger (OR: 1.157; CI95%: 1.080-1.240; P < 0.001), and depression (OR: 1.071; CI95%: 1.029-1.116; P = 0.001) are associated with poor treatment adherence; however, a high score on the acceptance subscale (OR: 0.913; CI95%: 0.880-0.948; P < 0.001) is associated with good treatment adherence. The greatest sensitivity among the subscales was observed in the denial and anger stages (area under the [ABC] curve: 0.597 in both). CONCLUSIONS: The FD-66 is an instrument with good construct validity as a tool for measuring the stages of grief and makes it possible to identify patients with CNCD that will adhere to treatment. We therefore recommend its use in outpatient medical consultations. Furthermore, our findings indicate that grief is a risk factor that increases poor treatment adherence.

OBJETIVO: Validar a construção da Escala facial de dor (EFD-66) como instrumento para medir as fases da dor e avaliar sua utilidade para discriminar, na consulta médica ambulatorial, os pacientes com doenças crônicas não transmissíveis (DCNT) que aderem ao tratamento medicamentoso. MÉTODOS: Estudo transversal para determinar a associação entre as fases da dor e o tratamento medicamentoso conduzido de abril a outubro de 2015. A coleta de dados foi realizada prospectivamente. Foram aplicados três instrumentos: uma ficha sociodemográfica, a escala EFD-66 e o teste de Morisky-Green. Foram recrutados pacientes com história de DCNT provenientes da Clínica de Medicina da Família "Gustavo A. Madero", na Cidade do México. Os dados foram analisados com os testes estatísticos apropriados. RESULTADOS: Foi estudada uma amostra de 165 pacientes. Observou-se que uma pontuação alta nas subescalas de negação (odds ratio [OR] 1,124; intervalo de confiança de 95% [IC95%] 1,066­1,186; P < 0,001), raiva (OR 1,157; IC95% 1,080­1,240; P < 0,001) e depressão (OR 1,071; IC95% 1,029­1,116; P = 0,001) está associada à não adesão ao tratamento medicamentoso. No entanto, uma pontuação alta na subescala de aceitação (OR 0,913; IC95% 0,880­0,948; P < 0,001) está associada à adesão ao tratamento medicamentoso. As subescalas com maior sensibilidade foram as fases de negação e raiva (área sob a curva [ASC]: 0,597 em ambas). CONCLUSÕES: A escala EFD-66 tem boa validade de construção como instrumento para medir as fases da dor e permite discriminar os pacientes com DCNT que aderem ao tratamento medicamentosos. Assim, recomendamos que esta escala seja aplicada em consultas médicas ambulatoriais. Além disso, nossos achados indicam que a dor é um fator de risco que contribui para a não adesão ao tratamento medicamentoso.

Physical Exercise and Dietary Supplementation in Middle-Aged and Older Women: A Systematic Review.

With the aging of the population in developed countries, the number of middle-aged and older women is progressively increasing. During this stage, women suffer from a number of signs and symptoms that could be reduced or treated with physical exercise and dietary supplements. The main objective of this study was to analyse the benefits of exercise and dietary supplements during menopause. MATERIALS AND METHODS: A systematic review of the scientific literature was performed according to the PRISMA 2020 protocol, searching the PubMed, Cochrane, Scopus, and WOS databases. Studies that met the inclusion criteria were assessed for methodological quality using the PEDro or AMSTAR-2 scales. RESULTS: The searches yielded a total of 104 results, of which 10 were selected, with methodological quality ranging from fair to excellent. Each article examined the combination of a dietary supplement plan versus a placebo; plus an exercise routine versus another routine or a sedentary lifestyle. The results showed the benefits of combining a nutritional supplementation plan with an exercise routine during menopause. CONCLUSIONS: The practice of weekly strength and endurance exercises, together with the consumption of certain dietary supplements, may be a good resource for coping with menopause in a healthy way.

Association of diarrheagenic Escherichia coli Pathotypes with infection and diarrhea among Mexican children and association of atypical Enteropathogenic E. coli with acute diarrhea.

Seventy-six children < or =2 years old were prospectively followed for 1 year in a peri-urban community of Mexico City to determine asymptomatic infection and acute diarrhea associated with diarrheagenic Escherichia coli pathotypes (DEPs). By use of a pathogen-specific multiplex PCR, DEPs were sought in 795 stool samples, of which 125 (16%) were positive for DEP; of these, 4 represented shedding episodes and 4 parasite coinfections. Most single-DEP infections (85/117) were asymptomatic (P < 0.001), and of the 32 DEP diarrhea episodes, 41% were associated with atypical enteropathogenic E. coli (aEPEC), 37.5% with enterotoxigenic E. coli, 9% with typical EPEC, 9% with enteroinvasive E. coli, and 3% with Shiga toxin-producing E. coli strains. Among the 76 children, 54 had at least one stool positive for DEP, of which 23 experienced a DEP-associated diarrhea episode. In the last group of children, DEP infection was significantly associated with a diarrhea episode (relative risk [RR] = 2.5; 95% confidence interval [CI], 1.79 to 3.57; P < 0.001), with ETEC (RR = 2.30; 95% CI, 1.49 to 3.54; P = 0.003) and aEPEC (RR = 1.92; 95% CI, 1.23 to 3.0; P = 0.019) being the pathotypes associated with diarrhea. aEPEC-associated diarrhea episodes were frequently in the <12-month age group (RR = 2.57; 95% CI, 1.05 to 6.27; P = 0.04). aEPEC infections were distributed all year round, but associated diarrheal episodes were identified from April to October, with a May-June peak (rainy season). Most ETEC infections and diarrhea episodes characteristically occurred during the summer (rainy season), with a diarrhea peak in August. Of all DEPs, only aEPEC was associated with acute diarrhea episodes lasting 7 to 12 days (P = 0.019). DEPs are important causes of community-acquired enteric infection and diarrhea in Mexican children.

Bacteriological quality of bottled water obtained from Mexico City small water purification plants: Incidence and identification of potentially pathogenic nontuberculous mycobacteria species.

The aim of this study was to determine the bacteriological quality of bottled water samples obtained from small purification plants located in Mexico City and to identify potentially pathogenic nontuberculous mycobacteria (NTM) species found in these samples. All 111 samples analyzed were positive for aerobic mesophilic bacteria (AMB) and 46 (41.4%) did not comply with Mexico's Official Guidelines. Sixty-nine (62.1%) and 23 (20.7%) water samples were positive for total coliforms (TC) and fecal coliforms (FC), respectively. A total of 81 (72.9%) of the water samples exceeded the maximum allowed limit stipulated in the guideline. Thirty-three (29.7%) of the purified water samples were positive for NTM, being recovered a total of 40 isolates. These NTM isolates were identified using three molecular markers (hsp65, rrs and rpoB genes) which corresponded to the fast-growing mycobacteria M. chelonae (n = 12), M. porcinum (n = 8), M. senegalense (n = 5), M. abscessus (n = 4), M. septicum (n = 4), M. wolinskyi (n = 3), M. mucogenicum (n = 2), M. fortuitum (n = 1) and M. sp. (n = 1). In seven purified water samples, two different NTM species were isolated simultaneously. Overall, these results showed that most of the purified bottled water samples analyzed in this study had unsatisfactory microbiological quality and some harbored NTM associated with illness. Our data could hasten health authorities to intensify efforts in the routine monitoring of activities in the purified bottled water industry in order to supply safe and healthy water to the public.

La medicalización de los servicios de salud y la publicidad masiva de medicamentos en la automedicación y la polifarmacia / Medicalization of Health Services and Massive Advertising of Drugs in Self-Medication and Polypharmacy

La medicalización de los servicios de salud y la publicidad masiva de medicamentos en la automedicación y la polifarmacia son temas relevantes de interés mundial. Se encuentran vinculados a la calidad de vida, el deterioro de la salud, la funcionalidad, la autonomía y los actuales modelos económicos y de salud pública. Estos mal manejados perpetúan un círculo perjudicial que trasciende las políticas públicas, las naciones y la sociedad en su conjunto. Ambos modifican el pronóstico de las enfermedades de base (transmisibles o no transmisibles), las comorbilidades, y los procesos farmacocinéticos y farmacodinámicos, cambian su índice terapéutico, y su relación entre las concentraciones para producir efectos terapéuticos o tóxicos. Ejemplos como la insuficiencia renal atribuida al consumo frecuente de antiinflamatorios no esteroideos y la suspensión de metformina en personas adultas mayores con un filtrado glomerular < 30 ml/min o la presencia de comorbilidades(AU)

The medicalization of health services and the massive advertising of drugs in self-medication and polypharmacy are relevant issues of global interest. They are linked to the quality of life, deterioration of health and current autonomy of the economic and public health models. The medicalization of poorly managed services perpetuates a harmful circle that transcends public policies, modifying the prognosis of underlying communicable and non-communicable diseases, comorbidities, and pharmacokinetic and pharmacodynamic processes. As a result of these problems, alterations appear in the therapeutic index and its relationship between concentrations to produce therapeutic or toxic effects. This global problem of polypharmacy in public health mainly affects the elderly(A)

Correlación entre las pruebas de antígeno prostático específico rápida y sérica / Correlation between rapid and serum prostate-specific antigen tests

Introducción: Al día de hoy no se ha alcanzado un consenso sobre el mejor enfoque para realizar el tamizaje y la detección precoz del Cáncer de Próstata (CaP), en la población. No obstante, hay programas que recomiendan la utilización de la prueba de antígeno prostático específico rápida para la detección de CaP sin un análisis de correlación frente a la prueba sérica. Objetivo: Identificar la correlación entre las pruebas de antígeno prostático específico rápida y sérica, en la población mexicana. Métodos: Se realizó un estudio descriptivo, transversal y retrospectivo, bajo un muestreo no probabilístico por conveniencia. En el período comprendido entre el 25 de mayo al 13 de julio de 2017. Se calcularon los coeficientes de correlación punto biserial (r pb ) y phi (r phi ). Resultados: Se incluyeron 1 635 registros, principalmente de la Ciudad de México y del Estado de México (n= 1 398; 85,5 por ciento, IC95 por ciento 81-89,9). La edad promedio fue de 51 años (DE= 7,68). El valor promedio de antígeno prostático sérico fue de 1,49 ng/mL (DE= 1,91). La proporción de hombres con una prueba rápida positiva (n=60; 3,7 por ciento; IC95 por ciento 2,9-4,6) fue menor (p= 0,0415) en comparación con la proporción de pacientes con una prueba sérica ≥ 4 ng/mL (n=85; 5,2 por ciento; IC95 por ciento 4,1-6,3). El número de casos dobles negativos fue de 1 530 (93,6 por ciento; IC95 por ciento 92,3-94,6) y de dobles positivos fue de 40 (2,4 por ciento; IC95 por ciento1,7-3,2). Los coeficientes de correlación punto biserial y phi mostraron una correlación baja entre la prueba rápida y la prueba sérica de antígeno prostático (rpb= 0,469; p < 0,001; r2= 0,2199 y r ph i= 0,540; p < 0,001; r2= 0,2916). Conclusiones: La prueba de antígeno prostático específico rápida es una herramienta conveniente para los programas de detección de alteración prostática en unidades médicas del primer nivel de atención, donde la prueba sérica no se puede realizar, al ser una prueba con una baja sensibilidad y con un bajo coeficiente de correlación respecto de la prueba de antígeno prostático específico sérica, esto es un punto importante que debe considerarse al diseñar programas de detección oportuna de cáncer de próstata(AU)

Introduction: To date, no consensus has been reached on the best approach for screening and early detection of Prostate Cancer (PCa) in the population. However, there are programs recommending the use of the rapid prostate-specific antigen test for the detection of PCa without a correlation analysis versus the serum test. Objective: To identify the correlation between rapid and serum prostate specific antigen tests in the Mexican population. Methods: A descriptive, cross-sectional and retrospective study was carried out, under a non-probabilistic convenience sampling from May 25 to July 13, 2017. The correlation coefficients of point biserial (rpb) and phi (rphi) were calculated. Results: One thousand six hundred thirty five (1,635) records were included, mainly from Mexico City and the State of Mexico (n= 1,398; 85.5 percent, 95 percent CI 81-89.9). The average age was 51 years (SD= 7.68). The mean value of serum prostate antigen was 1.49 ng/ml (SD= 1.91). The proportion of men with positive rapid test (n=60; 3.7 percent; 95 percent CI 2.9-4.6) was lower (p= 0.0415) compared to the proportion of patients with a serum test ≥ 4 ng/ml (n= 85; 5.2 percent; 95 percent CI 4.1-6.3). The number of double negative cases was 1,530 (93.6 percent; CI95 percent 92.3-94.6) and of double positives was 40 (2.4 percent; CI95 percent 1.7-3.2). The point biserial and phi correlation coefficients showed low correlation between the rapid test and the serum prostate antigen test (rpb= 0.469; p < 0.001; r2= 0.2199 and rphi= 0.540; p < 0.001; r2= 0. 2916). Conclusions: The rapid prostate-specific antigen test is a convenient tool for prostatic alteration detection programs in primary care medical units, where the serum test cannot be performed, however, as it is a test with low sensitivity and with low correlation coefficient with respect to serum prostate-specific antigen testing, this is an important point to consider when designing prostate cancer early detection programs(AU)

[Human papillomavirus infection and its correlates with clinically relevant gynecological and obstetric conditions: A cross-sectional study]. / Infección por el virus del papiloma humano y su correlación con situaciones ginecológicas u obstétricas de relevancia clínica: estudio transversal.

BACKGROUND AND OBJETIVE: To analyze the prevalence of human papillomavirus (HPV) infection and the possible epidemiological association with conditions of clinical relevance in women. MATERIAL AND METHODS: A cross-sectional study from Mexico City was conducted from January 2012 to December 2014. HPV molecular detection was performed on cervical samples. Data were analyzed with appropriated statistic tests. RESULTS: A total of 1,604 females (median 47, interquartile range 38-54) were analyzed. Global prevalence of infection for any HPV is 9.91% (95% CI 8.6-11.3). An association between infection with 16-HPV and number of abortions (NA) (OR=1.427; 95% CI 1.091-1.866), by univariate regression model (UVRM) was estimated. Moreover, menarche (OR=1.566; 95% CI 1.079-2.272), NA (OR=1.570; 95% CI 1.106-2.227) and number of pregnancies (NP) (OR=0.461; 95% CI 0.260-0.818) have a direct and inverse association with infection by genotype 18 of HPV, respectively. Also, infection with HR-HPV genotypes has an inverse association with NP (OR=0.791; 95% CI 0.707-0.884) by normal labor (OR=0.867; 95% CI 0.767-0.979) and NA (OR=0.715; 95% CI 0.534-0.959) (UVRM), and a direct association with number of sexual partners (OR=1.082; 95% CI 1.015-1.154). Onset of sexual activity has an inverse association with infection by genotype 16- (UVRM: OR=0.814; 95% CI 0.715-0.926; multinomial regression model (MNRM): OR=0.803; 95% CI 0.702-0.918) and HR-HPV (UVRM: OR=0.933; 95% CI 0.889-0.980, and MNRM: OR=0.912; 95% CI 0.867-0.959), all P values were lower than .03. CONCLUSIONS: Prevalence of HPV cervical infection is different according to age and it is associated with several medical conditions of clinical relevance in women.

[Laparoscopic hysterectomy in the surgical treatment of gynecological malignant and premalignant diseases]. / Histerectomía laparoscópica en el tratamiento quirúgico de enfermedades ginecológicas malignas y premalignas.

INTRODUCTION: Laparoscopic hysterectomy (LH) is a safe surgical approach that offers patients a faster recovery. However, its use in malignant or premalignant gynecological lesions is not well established. The objective of the present study was to show the feasibility of LH in a tertiary cancer center. MATERIAL AND METHODS: We conducted a descriptive analysis of patients with histologically proven malignant or premalignant uterine lesions who underwent to LH. Surgical time, bleeding complications, and hospital stay were evaluated. RESULTS: Twenty-five patients were included with a mean age of 45 years. Ten LH (40%) with or without salpingo-oophorectomy for premalignant or preinvasive malignant lesions were done, five surgical staging procedures for endometrial cancer (20%) and seven radical hysterectomies for cervical cancer (28%). In three patients, conversion from laparotomy (12%) was necessary for operative complications (two cases) or technical problems (one case). Mean operative time for the entire group was 207 min, mean bleeding 204 mL and mean hospital stay was 2.5 days. Postoperative complications were present in two patients, hematoma in the vaginal cupola (one case) and temporary bladder dysfunction (one case). CONCLUSIONS: In the present trial we described our initial experience in LH for the treatment of malignant and premalignant gynecologic diseases. Our results suggest that it is a safe and feasible surgical approach. Long-term surveillance studies are necessary for the evaluation of recurrence patterns and overall survival.

Microbiological Quality of Ready-to-Eat Vegetables Collected in Mexico City: Occurrence of Aerobic-Mesophilic Bacteria, Fecal Coliforms, and Potentially Pathogenic Nontuberculous Mycobacteria.

The aims of this study were to evaluate the microbiological quality and the occurrence of nontuberculous mycobacteria (NTM) in a variety of salads and sprouts from supermarkets and street vendors in Mexico City. Aerobic-mesophilic bacteria (AMB) were present in 100% of RTE-salads samples; 59% of samples were outside guidelines range (>5.17 log10 CFU per g). Although fecal coliforms (FC) were present in 32% of samples, only 8% of them exceeded the permissible limit (100 MPN/g). Regarding the 100 RTE-sprouts, all samples were also positive for AMB and total coliforms (TC) and 69% for FC. Seven NTM species were recovered from 7 salad samples; they included three M. fortuitum, two M. chelonae, one M. mucogenicum, and one M. sp. Twelve RTE-sprouts samples harbored NTM, which were identified as M. porcinum (five), M. abscessus (two), M. gordonae (two), M. mucogenicum (two), and M. avium complex (one). Most RTE-salads and RTE-sprouts had unsatisfactory microbiological quality and some harbored NTM associated with illness. No correlation between the presence of coliforms and NTM was found. Overall, these results suggest that RTE-salads and RTE-sprouts might function as vehicles for NTM transmission in humans; hence, proper handling and treatment before consumption of such products might be recommendable.

Abstract Introduction: An integral diagnosis of population contemplates within its components the population demographic analysis that is indispensable in the formulation of public policies. Population policy has a clearly transversal nature, since all actions in the economic, social, political, cultural, geographical, and obviously, demographic fields, have direct or indirect repercussions on it. Objectives: To determine the population dynamics and the global growth of the older adult population (OAP) of 60 years and more. Materials and methods: Cross-sectional, retrospective study. The information was obtained from the statistical yearbooks of the institute of security and social services of state workers, Mexico (1999-2015). Several demographic ageing indicators were analyzed. Results: There was a constant increase in percentage points in the proportion of OAP, index of ageing, demographic dependency ratio of old age, global index of dependence, index of dependence of old people, and index of the active population structure (6, 19.2, 15.5, 8.5, 8.2 and 31.2%, respectively). The indicator global index of dependence and masculinity showed a decrease (0.6 and 3.1%, respectively). Conclusions: Our data provide evidence that suggests modifying and generating public policies according to OAP.

Epidemiological association between body fat percentage and cervical cancer: a cross-sectional population-based survey from Mexico.

BACKGROUND AND AIMS: Various studies have reported a direct association of cervical cancer risk with obesity and weight but not with the body fat percentage (BFP). The aim of this study was to analyze various anthropometric measures as potential risk factors for cervical cancer. METHODS: A total of 20,236 women were included in a cross-sectional population-based survey. Obesity was defined according to the World Health Organization criteria, and central obesity was ≥80 cm; the BFP was defined using the Deurenberg equation (BFP = 1.2 [BMI] + 0.23 [age] - 10.8 [sex] - 5.4). The odds ratio (OR) was estimated from the chi square test and logistic regression models. RESULTS: The prevalence of cervical cancer increased from 514 (95% confidence interval [CI] 321, 707) and 680 (95% CI 494, 866) to 732 (95% CI 535, 928) per 100,000 inhabitants in subjects with a normal weight, subjects who were overweight and subjects who were obese, respectively. Moreover, an association between cervical cancer and BFP (OR 1.027; CI 95% 1.006, 1.048; p = 0.012) was observed, and the risk increased with a BFP ≥45% (OR 2.369; CI 95% 1.284, 4.369; p = 0.006). CONCLUSIONS: These data suggest a trend between the body mass index and the increasing prevalence of cervical cancer. In addition, the data showed a significant association between the BFP and cervical cancer, and this epidemiological association was higher as the BFP increased.

Presence of faecal coliforms, Escherichia coli and diarrheagenic E. coli pathotypes in ready-to-eat salads, from an area where crops are irrigated with untreated sewage water.

Consumption of ready-to-eat (RTE) salads has increased worldwide. Consequently, the number of outbreaks caused by food-borne pathogens, including diarrheagenic E. coli pathotypes (DEPs), associated with the consumption of RTE-salads has increased. DEPs include enterotoxigenic (ETEC), typical and atypical enteropathogenic (tEPEC, aEPEC), enteroinvasive (EIEC), enteroaggregative (EAEC), diffuse adherent (DAEC) and Shiga toxin-producing (STEC) E. coli. In less-developed areas of the world, fresh crops continue to be irrigated with untreated sewage water. The aims of this study were to evaluate the microbiological quality and prevalence of DEPs in RTE-salads of raw vegetables, purchased from restaurants at Pachuca-City, Hidalgo, Mexico, where most locally consumed vegetables are irrigated with untreated sewage water. A total of 130 salads were purchased from restaurants of three categories: A) national chain restaurants and B) local restaurants, both with the H distinctive (a recognition that the Secretary of Tourism grants to restaurants that manage supplies with high levels of hygiene); and C) local small inexpensive restaurants without H distinctive. A total of 6 restaurants were included, 2 per category (A(1-2), B(1-2), C(1-2)). Each sample was tested for the presence of faecal coliforms (FC) and E. coli by standard procedures. E. coli strains were further characterized for the presence of DEPs loci by two multiplex polymerase chain reactions. Among the 130 salad samples 99% (129) were contaminated with FC; 85% (110/129) harboured E. coli and 7% (8/110) DEPs. The amount of positive salad samples for FC and E. coli was similar between restaurants and categories. The FC mean (571 FC/g) of all samples was significantly higher (p<0.001) than the E. coli mean (63 E. coli/g). A weak correlation of 7.7% (r(2)=0.077, p=0.003) between median FC and E. coli MPN (most probable number) per sample was found. Of the 8 salad samples contaminated with DEPs, 2 were spinach salads from restaurant A(2) and 3 were (Mixed salad) samples from each C restaurant. Three samples harboured non-O157 STEC strains, 2 EIEC, 1 ETEC and 2 samples had non-O157 STEC and EIEC strains, simultaneously. A significant difference (p=0.008) between the prevalence of E. coli vs. DEPs was observed. Independently of the restaurants' overall hygienic status, most RTE-salads had a poor microbiological quality and some harboured DEPs that have been associated with illness in Mexico. Health authorities should focus on implementing DEPs screening in raw vegetables and enforcing the legislation that forbids irrigation with untreated sewage water of both root and leafy vegetables.
