Modifying effect of urban parks on socioeconomic inequalities in diabetes prevalence: a cross-sectional population study of Madrid City, Spain.

BACKGROUND: Evidence has shown contradicting results on how the density of urban green spaces may reduce socioeconomic inequalities in type 2 diabetes (equigenic hypothesis). The aim of this study is to test whether socioeconomic inequalities in diabetes prevalence are modified by park density. METHODS: We designed a population-wide cross-sectional study of all adults registered in the primary healthcare centres in the city of Madrid, Spain (n=1 305 050). We obtained georeferenced individual-level data from the Primary Care Electronic Health Records, and census-tract level data on socioeconomic status (SES) and park density. We modelled diabetes prevalence using robust Poisson regression models adjusted by age, country of origin, population density and including an interaction term with park density, stratified by gender. We used this model to estimate the Relative Index of Inequality (RII) at different park density levels. FINDINGS: We found an overall RII of 2.90 (95% CI 2.78 to 3.02) and 4.50 (95% CI 4.28 to 4.74) in men and women, respectively, meaning that the prevalence of diabetes was three to four and a half times higher in low SES compared with high SES areas. These inequalities were wider in areas with higher park density for both men and women, with a significant interaction only for women (p=0.008). INTERPRETATION: We found an inverse association between SES and diabetes prevalence in both men and women, with wider inequalities in areas with more parks. Future works should study the mechanisms of these findings, to facilitate the understanding of contextual factors that may mitigate diabetes inequalities.

Implementation of an Ecological Momentary Assessment (EMA) in Naturalistic Psychotherapy Settings: Qualitative Insights from Patients, Therapists, and Supervisors Perspectives.

Ecological momentary assessment (EMA) allows measuring intra-individual processes moment by moment, identifying and modeling, in a naturalistic way, individual levels and changes in different psychological processes. However, active EMA requires a high degree of adherence, as it implies a significant burden for patients. Moreover, there is still no consensus on standardized procedures for implementation. There have been few results in detecting desirable characteristics for the design and implementation of an EMA device. Studies that address these issues from the perspectives of participants in psychotherapeutic processes are needed. To analyze the perspectives of patients, therapists and supervisors on the implementation of an EMA device in a psychotherapeutic treatment for depression. The sample will include eight patients, eleven therapists and five supervisors, taken from a research project that implemented an EMA system for monitoring the dynamics of affectivity at the beginning of psychotherapies for depression. Semi-structured interviews specific to each group are being conducted and analyzed from a qualitative approach based on consensual qualitative research (CQR). Participants reported having a positive evaluation of the study's informational resources and implementation. Difficulties were expressed in responding in the morning hours and the importance of having a customized EMA that is tailored to the needs of the patients was expressed. Furthermore, patients and therapists agreed that the impact of the use of the monitoring system on treatment was neutral or positive. In contrast, patients considered the EMA to be positive for their daily life.

A nation-wide analysis of socioeconomic and geographical disparities in the prevalence of obesity and excess weight in children and adolescents in Spain: Results from the ENE-COVID study.

OBJECTIVE: To estimate national and provincial prevalence of obesity and excess weight in the child and adolescent population in Spain by sex and sociodemographic characteristics, and to explore sources of inequalities in their distribution, and their geographical patterns. METHODS: ENE-COVID is a nationwide representative seroepidemiological survey (68 287 participants) stratified by province and municipality size (April-June 2020). Participants answered a questionnaire which collected self-reported weight and height, that allowed estimating crude and model-based standardized prevalences of obesity and excess weight in the 10 543 child and adolescent participants aged 2-17 years. RESULTS: Crude prevalences (WHO growth reference) were higher in boys than in girls (obesity: 13.4% vs. 7.9%; excess weight: 33.7% vs. 26.0%; severe obesity: 2.9% vs. 1.2%). These prevalences varied with age, increased with the presence of any adult with excess weight in the household, while they decreased with higher adult educational and census tract average income levels. Obesity by province ranged 1.8%-30.5% in boys and 0%-17.6% in girls; excess weight ranged 15.2%-49.9% in boys and 10.8%-40.8% in girls. The lowest prevalences of obesity and excess weight were found in provinces in the northern half of Spain. Sociodemographic characteristics only partially explained the observed geographical variability (33.6% obesity; 44.2% excess weight). CONCLUSIONS: Childhood and adolescent obesity and excess weight are highly prevalent in Spain, with relevant sex, sociodemographic and geographical differences. The geographic variability explained by sociodemographic variables indicates that there are other potentially modifiable factors on which to focus interventions at different geographic levels to fight this problem.

Development and validation of a low-cost laparoscopic simulation box.

INTRODUCTION: The acquisition of laparoscopic technique skills in an operating room is conditioned by the expertise of the tutor and the number of training interventions by the trainee. For students and surgeons to use a laparoscopic simulator to train their skills, it must be validated beforehand. METHODS: A laparoscopic simulator box was designed, along with 6 interchangeable training games. The simulator was validated by a group of 19 experts, physicians with an experience from at least 100 laparoscopic surgeries, and 20 students of 4th to 6th grades of medical school (non-experts). To evaluate its construct validity, time-to-completion and the number of successfully completed games were assessed. We used 11 and 9-item questionnaires to gather information on content and face validity respectively. In both questionnaires, answers were collected through Likert-type scales, scored from 1 to 5. RESULTS: The group of experts required less time and successfully completed more games than the group of non-experts (p < 0.01). The group of non-experts gave a score ≥ 4 points on each of the questions regarding the content validity of the tool, however, the experts rated with a significant lower mean score the need for the simulator to learn the surgical technique (3.68 points; p < 0.01). Regarding the face validity, all items were graded with a score ≥ 4 points except for the question relating to the spatial realism (3.82 points). CONCLUSION: The laparoscopy simulation box and the games were valid means for training surgeons and medical students to develop the skills required for the laparoscopic technique.

Serum Cannabinoid 24 h and 1 Week Steady State Pharmacokinetic Assessment in Cats Using a CBD/CBDA Rich Hemp Paste.

Hemp based cannabinoids have gained popularity in veterinary medicine due to the potential to treat pain, seizure disorders and dermatological maladies in dogs. Cat owners are also using hemp-based products for arthritis, anxiety and neoplastic disorders with no studies assessing hemp cannabinoids, namely cannabidiol efficacy, for such disorders. Initial twenty-four pharmacokinetic and chronic dosing serum concentration in cats are sparse. The aim of our study was to assess 8 cats physiological and 24 h and 1-week steady state pharmacokinetic response to a cannabidiol (CBD) and cannabidiolic acid (CBDA) rich hemp in a palatable oral paste. Using a standard dose of paste (6.4 mg/CBD + CBDA 5.3 mg/gram) across 8 cats weighing between 4.2 and 5.4 kg showed an average maximal concentration of CBD at 282.0 ± 149.4 ng/mL with a half-life of ~2.1 ± 1.1 h, and CBDA concentrations of 1,011.3 ± 495.4 ng/mL with a half-life of ~2.7 ± 1.4 h, showing superior absorption of CBDA. After twice daily dosing for 1 week the serum concentrations 6 h after a morning dosing showed that the acidic forms of the cannabinoids were approximately double the concentration of the non-acidic forms like CBD and Δ9- tetrahydrocannabinol (THC). The results of this study compared to two other recent studies suggest that the absorption in this specific paste product may be superior to oil bases used previously, and show that the acidic forms of cannabinoids appear to be absorbed better than the non-acidic forms. More importantly, physical and behavioral examinations every morning after dosing showed no adverse events related to neurological function or behavioral alterations. In addition, bloodwork after 1 week of treatment showed no clinically significant serum biochemical alterations as a reflection of hepatic and renal function all remaining within the reference ranges set by the diagnostic laboratory suggesting that short-term treatment was safe.

Social determinants of violence against women in Panama: results from population-based cross-sectional studies and a femicide registry.

BACKGROUND: We aimed to investigate the prevalence of violence against women (VAW) in Panama and its association with social determinants of health (SDH) and to estimate the femicide rates from 2014 to 2017. METHODS: Data were derived from three cross-sectional population-based studies. Logistic regression models were used to estimate the association between SDH and VAW, expressed as odds ratios (ORs) and 95% confidence intervals (CIs). Age-standardized femicide rates were estimated using data from the Public Ministry. RESULTS: Compared to the reference categories, women in the lowest quintile (Q) of income distribution (Q1: OR 4.0 [95% CI 1.4-11.7], Q2: OR 3.0 [95% CI 1.1-7.9]), divorced/separated women (OR 1.5 [95% CI 1.0-2.1]) and those in the age categories 25-33 y and 34-49 y (OR 1.9 [95% CI 1.2-3.1]) were more likely to have experienced violence in the past year. Indigenous ethnicity (OR 2.3 [95% CI 1.3-4.1]), age 15-19 y (OR 1.8 [95% CI 1.1-2.9]) and lowest education levels (very low: OR 4.7 [95% CI 1.4-15.5]; low: OR 4.5 [95% CI 1.4-14.6]) were associated with permissive attitudes towards violence. Indigenous (OR 2.7 [95% CI 1.3-6.1]), Afro-Panamanians (OR 3.1 [95% CI 1.3-7.6]) and education level (low: OR 2.5 [95% CI 1.2-4.9]; medium: OR 3.0 [95% CI 1.4-6.6]) were associated with physical/sexual intimate partner violence. Standardized adjusted femicide rates (×100 000) from 2015 to 2017 were 1.5, 0.9 and 0.8, respectively. CONCLUSIONS: Our findings highlight the importance of prevention programmes.

Dosis Diaria Definida de antibióticos en pacientes atendidos en hospitales públicos de Panamá

Objetivo: Determinar la Dosis Diaria Definida (DDD) de antibióticos utilizados en los Servicios de Medicina Interna de cuatro hospitales públicos en Panamá. Métodos: Se escogió una muestra a conveniencia de 4 hospitales públicos de segundo nivel de atención de la seguridad social y Ministerio de Salud, atendiendo características en cuanto a ubicación en provincias, población atendida, servicios médicos ofrecidos y con Dosis Unitaria en funcionamiento. Se obtuvieron datos de los pacientes hospitalizados entre los meses de enero a marzo del 2017 y la información era registrada en una base de datos anotándose generales del paciente, diagnósticos, antibióticos, dosis, frecuencia, tiempo de tratamiento. Igualmente se anotaron los consumos y costos unitarios de todos los antibióticos usados en los hospitales durante el año 2016, para calcular la DDD y Dosis Diaria Prescrita. Resultados: La oxacilina fue el antibiótico con mayor DDD días cama con 60.5, luego le siguen ceftriaxona (45.2), cefalotina (35.5), clindamicina (35.5). Por grupo farmacológico, las cefalosporinas tienen consumos más altos con 87.6 DDD días cama, la penicilina MRSA 60.5, la lincosamidas con 35.5 DDD días cama, seguido de las quinolonas con 29.3. Conclusiones: Los resultados pueden ser utilizados para implementar programas para mejorar el uso racional y gasto de antibióticos a nivel hospitalario y que la DDD se use para medir el consumo y a la vez propiciar el control de antibióticos a través de comunicaciones escritas con los médicos tratantes. Se deben realizar estudios de DDD días cama relacionando con los aspectos microbiológicos para relacionar mejor el uso de los antibióticos. (provisto por Infomedic International)

Objective. Determine the Defined Daily Dose of antibiotics used in the Internal Medicine Services of 4 public hospitals in Panama. Methods. A convenience sample of 4 public hospitals of the second level of social security care and the Ministry of Health was chosen, considering characteristics in terms of location in the provinces, population served, medical services offered and with Unit Dose in operation. Data were obtained from hospitalized patients between the months of January to March 2017 and the information was recorded in a database, noting general patient reports, diagnoses, antibiotics, dose, frequency, treatment time. Likewise, the consumptions and unit costs of all antibiotics used in hospitals during 2016 were recorded to calculate the DDD and Prescribed Daily Dose. Results. Oxacillin was the antibiotic with the highest DDD bed days with 60.5, followed by ceftriaxone (45.2), cephalothin (35.5), and clindamycin (35.5). By pharmacological group, cephalosporins have higher intakes with 87.6 DDD bed days, penicillin MRSA 60.5, and lincosamides with 35.5 DDD bed days, followed by quinolones with 29.3. Conclusions. The results can be used to implement programs to improve the rational use and expense of antibiotics at the hospital level and that the DDD is used to measure the consumption and at the same time promote the control of antibiotics through written communications with the treating physicians. Bed-day DDD studies should be carried out relating to microbiological aspects to better relate the use of antibiotics. (provided by Infomedic International)

Pathogenicity Assessment of Colombian Strains of Candida auris in the Galleria mellonella Invertebrate Model.

Candida auris, first described in 2009, is an opportunistic pathogenic yeast that causes nosocomial outbreaks around the world, with high mortality rates associated with therapeutic failure. In this study, we evaluated the pathogenicity of 107 isolates from two cities in Colombia, associated with fungemia or colonization processes; to achieve this, we used the Galleria mellonella invertebrate model to compare pathogenicity. Our results showed that less than half of the total isolates of C. auris presented a high pathogenicity compared to the reference strain SC5314, and most of those highly pathogenic strains were from colonization processes. We observed that there was formation of large aggregates of cells that cannot be disrupted easily, without statistically significant differences between the pathogenicity of the aggregated and non-aggregated strains. In addition, protease activity was observed in 100% of the C. auris strains; phospholipase and hemolysin activity were observed in 67.3 and 68.2% of the studied strains, respectively. In conclusion, these results highlight the utility of determining survival using G. mellonella, which allowed us to provide new information on the pathogenicity, enzymatic activity, and the relationship of the aggregated and non-aggregated phenotypes of C. auris in this model.

Social inequalities in tobacco-attributable mortality in Spain. The intersection between age, sex and educational level.

INTRODUCTION: First study of social inequalities in tobacco-attributable mortality (TAM) in Spain considering the joint influence of sex, age, and education (intersectional perspective). METHODS: Data on all deaths due to cancer, cardiometabolic and respiratory diseases among people aged ≥35 years in 2016 were obtained from the Spanish Statistical Office. TAM was calculated based on sex-, age- and education-specific smoking prevalence, and on sex-, age- and disease-specific relative risks of death for former and current smokers vs lifetime non-smokers. As inequality measures, the relative index of inequality (RII) and the slope index of inequality (SII) were calculated using Poisson regression. The RII is interpreted as the relative risk of mortality between the lowest and the highest educational level, and the SII as the absolute difference in mortality. RESULTS: The crude TAM rate was 55 and 334 per 100,000 in women and men, respectively. Half of these deaths occurred among people with the lowest educational level (27% of the population). The RII for total mortality was 0.39 (95%CI: 0.35-0.42) in women and 1.61 (95%CI: 1.55-1.67) in men. The SII was -41 and 111 deaths per 100,000, respectively. Less-educated women aged <55 years and men (all ages) showed an increased mortality risk; nonetheless, less educated women aged ≥55 had a reduced risk. CONCLUSIONS: TAM is inversely associated with educational level in men and younger women, and directly associated with education in older women. This could be explained by different smoking patterns. Appropriate tobacco control policies should aim to reduce social inequalities in TAM.

Introducción: la obesidad es un grave problema de salud en México, ya que su prevalencia se ha incrementado de forma acelerada en los últimos años. De acuerdo con los resultados de la Encuesta Nacional de Salud y Nutrición (ENSANUT) del año 2012, el 70% de las personas mayores de 20 años y el 39% de los adolescentes de 12 a 19 años en el estado de Colima tenían problemas de sobrepeso y obesidad. El objetivo de este trabajo es proporcionar la experiencia documentada mediante la metodología del proceso de atención de enferme- ría (PAE) en un adulto con diagnóstico de obesidad. Desarrollo: se realizó una valoración integral mediante la guía de valoración de dominios y clases y además se consultó la taxonomía II de la North American Nursing Diagnosis Association (NANDA) para la estructuración de los diagnósticos con base en las respuestas identificadas; el plan de cuidados se realizó a partir del modelo de promoción de la salud de Nola J. Pender, y los resultados y las intervenciones de enfermería se redactaron en el lenguaje disciplinar, con cumplimiento eficiente del plan de cuidados. Conclusión: la metodología del proceso de enfermería permite la sistematización del cuidado, así como la aplicación de conocimientos, habilidades y actitudes con sentido huma- no, que promueven la mejoría de la persona con un proceso mórbido para alcanzar el bienestar del paciente.

Introduction: Obesity is a serious health problem in Mexico, since its prevalence has increased rapidly in recent years. According to the results of the National Health and Nutrition Survey (ENSANUT), in 2012, in the state of Colima, 70% of people over 20 years old and 39% of adolescents between 12 and 19 years old had overweight and obesity problems. The aim of this work is to provide documented experience through the Nursing Care Process (PAE) methodology in an adult diagnosed with obesity. Development: A comprehensive assessment was carried out using the domains and classes assessment guide; besides, the taxonomy II of the North American Nursing Diagnosis Association (NANDA) was consulted for structuring the diagnoses based on the identified responses, the plan of care was carried out based on the Nola J. Pender's Health Promotion Model, and the results and nursing interventions were written with the disciplinary language, carrying out the fulfillment of the care plan. Conclusion: The methodology of the nursing process allows the systematization of care, as well as the application of knowledge, skills and attitudes with a human sense, which promote the improvement of the person with a morbid process and achieving the well-being of the patient.

Changes in individual and contextual socio-economic level influence on reproductive behavior in Spanish women in the MCC-Spain study.

BACKGROUND: The association between socioeconomic level and reproductive factors has been widely studied. For example, it is well known that women with lower socioeconomic status (SES) tend to have more children, the age at first-born being earlier. However, less is known about to what extent the great socioeconomic changes occurred in a country (Spain) could modify women reproductive factors. The main purpose of this article is to analyze the influence of individual and contextual socioeconomic levels on reproductive factors in Spanish women, and to explore whether this influence has changed over the last decades. METHODS: We performed a cross-sectional design using data from 2038 women recruited as population-based controls in an MCC-Spain case-control study. RESULTS: Higher parent's economic level, education level, occupational level and lower urban vulnerability were associated with higher age at first delivery and lower number of pregnancies. These associations were stronger for women born after 1950: women with unfinished primary education had their first delivery 6 years before women with high education if they were born after 1950 (23.4 vs. 29.8 years) but only 3 years before if they were born before 1950 (25.7 vs. 28.0 years). For women born after 1950, the number of pregnancies dropped from 2.1 (unfinished primary school) to 1.7 (high education), whereas it remained almost unchanged in women born before 1950. CONCLUSIONS: Reproductive behavior was associated with both individual and area-level socio-economic indicators. Such association was stronger for women born after 1950 regarding age at first delivery and number of pregnancies and for women born before 1950 regarding consumption of hormonal contraceptives or postmenopausal therapy.

Social inequalities in cardiovascular mortality in Spain from an intersectional perspective.

INTRODUCTION AND OBJECTIVES: There is an interaction between age, sex, and educational level, among other factors, that influences mortality. To date, no studies in Spain have comprehensively analyzed social inequalities in cardiovascular mortality by considering the joint influence of age, sex, and education (intersectional perspective). METHODS: Study of all deaths due to all-cause cardiovascular disease, ischemic heart disease, heart failure, and cerebrovascular disease among people aged ≥ 30 years in Spain in 2015. Data were obtained from the Spanish Office of Statistics. The relative index of inequality (RII) and the slope index of inequality (SII) were calculated by using Poisson regression models with age-adjusted mortality. The RII is interpreted as the relative risk of mortality between the lowest and the highest educational level, and the SII as the absolute difference in mortality. RESULTS: The RII for all-cause cardiovascular mortality was 1.88 (95%CI, 1.80-1.96) in women and 1.44 (95%CI, 1.39-1.49) in men. The SII was 178.46 and 149.43 deaths per 100 000, respectively. The greatest inequalities were observed in ischemic heart disease and heart failure in younger women, with a RII higher than 4. There were no differences between sexes in inequalities due to cerebrovascular disease. CONCLUSIONS: Cardiovascular mortality is inversely associated with educational level. This inequality mostly affects premature mortality due to cardiac causes, especially among women. Monitoring this problem could guide the future Cardiovascular Health Strategy in the National Health System, to reduce inequality in the first cause of death.

End-stage renal disease-financial costs and years of life lost in Panama: a cost-analysis study.

OBJECTIVES: Central America is a region with an elevated burden of chronic kidney disease (CKD); however, the cost of treatment for end-stage renal disease (ESRD) remains an understudied area. This study aimed to investigate the direct costs associated with haemodialysis (HD) and peritoneal dialysis (PD) in public and private institutions in Panama in 2015, to perform a 5-year budget impact analysis and to calculate the years of life lost (YLL) due to CKD. DESIGN: A retrospective cost-analysis study using hospital costs and registry-based data. SETTING: Data on direct costs were derived from the public and private sectors from two institutions from Panama. Data on CKD-related mortality were obtained from the National Mortality Registry. METHODS: A budget impact analysis was performed from the payer perspective, and five scenarios were estimated, with the assumption that the mix of dialysis modality use shifts towards a greater use of PD over time. The YLL due to CKD was calculated using data recorded between 1 January 2015 and 31 December 2015. The linear method was utilised for the analyses with the population aged 20-77 years old. RESULTS: In 2015, the total costs for dialysis in the public sector ranged from ~US$7.9 million (PD) to US$62 million (HD). The estimated costs were higher in the scenario in which a decrease in PD was assumed. The average annual loss due to CKD was 25 501 808.40 US$-YLL. CONCLUSION: ESRD represents a major challenge for Panama. Our results suggest that an increased use of PD might provide an opportunity to substantially lower overall ESRD treatment costs.

Social determinants and cardiovascular disease mortality in Panama, 2012-2016.

BACKGROUND: The aims of this study were to determine the geographic and time variation of social determinants of health (SDH) and cardiovascular disease (CVD) mortality in Panama from 2012 to 2016, and to identify which of the SDH has the strongest correlation with a socioeconomic index (SEI). METHODS: We conducted an ecological study obtaining mortality from the National Mortality Register and socioeconomic variables derived from the National Household Survey (NHS). The International Classification of Diseases 10th revision codes I20-I25 and I60-I69 were used for ischemic heart disease (IHD) and stroke, respectively. Standardized age-adjusted mortality rates were calculated by direct method. Mortality rates and socioeconomic variables were evaluated together in a panel data model. A SEI was developed from factorial analysis by principal components with a polychoric correlation matrix. Provinces and regions were categorized in tertiles according to median value of the SEI score. RESULTS: The NHS evaluated an average of 15,919 households per year. The mean of age throughout the study period was 41 years. The average monthly income increased, from US$ (SD) 331.94 (5.38) in 2012, to 406.24 (5.81) in 2016, whereas the social security health coverage remained in a range of 57-58%. The mean number of school years was twelve. Significant geographical and temporal variations in social determinants and mortality rates were observed throughout the country. Colon, categorized in the middle tertile according to the SEI, presented higher IHD mortality rates. Darién (in the lowest SEI tertile) Colón and Herrera had higher stroke mortality rates. The SEI categorized indigenous territories in the lowest tertile. Total years of education was the strongest correlated variable with the SEI, when we excluded the population living in indigenous territories. However, when this population was included, social security coverage had the strongest correlation with the SEI. CONCLUSION: We observed geographical and temporal disparities in SDH and CVD mortality rates. Further epidemiological studies are warranted in the provinces of Colón, Darien, Herrera and Los Santos to explore in-depth the higher CVD mortality rates observed in these provinces.

Helicobacter pylori seroprevalence in Spain: influence of adult and childhood sociodemographic factors.

Helicobacter pylori (H. pylori) chronic infection causes severe digestive diseases, including gastric cancer, and certain strains entail a higher risk. Risk factors for this infection are still not fully understood. The aim of this study was to describe the association of adult and childhood sociodemographic factors with the seroprevalence of H. pylori, and with CagA and VacA antigen-specific seropositivity among H. pylori-seropositive individuals in the Spanish adult population. Serum antibody reactivity to H. pylori proteins was evaluated using multiplex serology in 2555 population-based controls enrolled in the MCC-Spain study, a multicase-control study recruiting participants from 2008 to 2013 in different areas of Spain. H. pylori seroprevalence was defined as seropositivity against at least four bacterial proteins. Information on sociodemographics, lifestyles, and environmental exposures was collected through personal interviews. Prevalence ratios and 95% confidence intervals were estimated using Poisson regression models to assess the association of lifetime sociodemographic factors with H. pylori seroprevalence and with seropositivity for CagA and VacA. H. pylori seroprevalence was 87.2%. Seropositivity was statistically significantly higher in men, increased with age, BMI, and number of siblings, and decreased with education and socioeconomic family level at birth. Among H. pylori-seropositive individuals, seropositivity was 53.3% for CagA, 61.4% for VacA, and 38.8% for both CagA and VacA. Ever smokers had lower seroprevalence for CagA and VacA than never smokers. H. pylori seroprevalence among this Spanish adult population was high and one third of the population was seropositive for two well-known markers of gastric cancer risk: CagA and VacA. Sex, age, education, and BMI were associated with H. pylori seroprevalence.

Análisis de los Determinantes Socioeconómicos del Gasto de Bolsillo en Medicamentos en Seis Zonas Geográficas de Panamá.

OBJETIVO: Caracterizar el gasto de bolsillo privado en medicamentos en función de los determinantes sociodemográficos y socioeconómicos. MATERIALES Y MéTODOS: La fuente de datos es la Encuesta de Gasto de Bolsillo en Medicamentos de 2014. Se caracterizó el gasto de bolsillo privado mediante variables explicativas sociodemográficas (SOD) y socioeconómicas (SES). Se hizo análisis factorial por componentes principales, regresión logística y lineal simple. RESULTADOS: Los Odds Ratio demuestran que la educación y la zona geográfica son determinantes fundamentales que inciden en el gasto de bolsillo. Los medicamentos son productos necesarios, en adición a que el gasto de bolsillo aumenta a un promedio del 2% por cada año de vida cronológica adicional. CONCLUSIONES: Existe mayor vulnerabilidad en las zonas más pauperizadas respecto del acceso a medicamentos, en especial en las indígenas e implica un mayor riesgo de gasto catastrófico a menor ingreso ante la mayor prevalencia de enfermedades crónicas.

Baseline characteristics, survival and direct costs associated to treatment of gastric cancer patients at the National Oncology Institute of Panama from 2012 to 2015: a hospital-based observational study.

OBJECTIVES: Comprehensive epidemiological and economic studies of gastric cancer (GC) in Panama are limited. This study aims to evaluate the association between socioeconomic and clinical variables with survival, describe the survival outcomes according to clinical stage and estimate the direct costs associated to GC care in a Panamanian population with GC. DESIGN AND SETTING: A retrospective observational study was conducted at the leading public institution for cancer treatment in Panama. PARTICIPANTS: Data were obtained from 611 records of patients diagnosed with gastric adenocarcinoma (codes C16.0-C16.9 of the International Classification of Diseases 10th revision), identified between 1 January 2012 and 31 December 2015. METHODS: Cox proportional hazards models were used to calculate HRs with 95% CI to examine associations between the variables and survival. Kaplan-Meier curves were used to assess overall and stage-specific survival. Direct costs (based on 2015 US$) were calculated per patient using standard costs provided by the institution for hospital admission (occupied bed-days), radiotherapy, surgery and chemotherapy, yielding total and overall mean costs (OMC). A comparison of OMC between groups (sex, social security status, clinical stage) was performed applying the bootstrap method with a t-test of unequal variances. RESULTS: An increased risk of dying was observed for patients without social security coverage (HR: 2.02; 95% CI 1.16 to 3.53), overlapping tumours (HR: 1.50; 95% CI 1.02 to 2.22), poorly differentiated tumours (HR: 2.27; 95% CI 1.22 to 4.22) and stage IV disease (HR: 5.54; 95% CI 3.38 to 9.08) (adjusted models). Overall 1-year survival rate was 41%. The estimated OMC of GC care per patient was 4259 US$. No statistically significant differences were found in OMC between groups. CONCLUSIONS: Socioeconomic disparities influence GC outcomes and healthcare utilisation. Policies addressing healthcare disparities related to GC are needed, as well as in-depth studies evaluating barriers of access to GC-related services.

[Quitting smoking and willingness to pay for cessation in Panama]. / Quiénes quieren dejar fumar y su disposición a pagar por cesación en Panamá.

OBJECTIVE:: To characterize the desire for cessation and willingness to pay for abandonment therapy. MATERIALS AND METHODS:: The data source is the Global Adult Tobacco Survey (GATS). Cessation and willingness to pay were characterized by sociodemographic (SD) and socioeconomic (SE) variables. Logistic regressions were performed to estimate associations. RESULTS:: A greater desire for cessation was observed in variables: women, education, non-governmental and inactive employees, rural areas, occasional smokers and middle income, and greater willingness to pay, in: education, over 60 years old, non-governmental, self-employed, urban area, occasional smokers and low median income. CONCLUSIONS:: There is a high relation between the desire for abandonment, and willingness to pay with SD and SE variables. Cessation therapies can be applied in work centers, and require a change of focus in the intervention.
