Non-Typhi, non-Paratyphi Salmonella-related hospitalisations in Spain: trends, clinical aspects, risk factors for worse prognosis and hospital costs.

This study reviews non-typhoid Salmonella (NTS)-related hospitalisations at National level in Spain between 2010 and 2015. NTS hospitalisations were obtained from the National Registry of Hospitalisations. A descriptive analysis of the hospitalisations was performed, including hospitalisation rates (HR) and case-fatality rates (CFR%) calculation. For those with NTS as Main Diagnosis logistic regression were used to estimate the relationship between the different factors and death outcome. 21,660 registered NTS-related hospitalisations were described (88.8% with Salmonella coded as Main Diagnosis). Average HR2010-2015 was 7.7 (range, 7.3 to 8.1) hospitalisations/100,000 population. Those with NTS infections as Secondary Diagnosis were on average (p < 0.001) older (47.9 vs. 36.5 years), presented worse Charlson Comorbidity Index (2.1 vs. 1.2), higher CFR% (4.8% vs. 0.7%), spent more days hospitalised (15.1 vs. 5.8 days), and generated more costs (6173 vs. 4272 euros/per hospitalisation) than those with NTS as Main Diagnosis. For those with NTS as Main Diagnosis increased risk of death was related to being > 64 years old (OR = 20.99; p < 0.001); presenting septicaemia (OR = 15.82; p < 0.001) or localised infections (OR = 3.98; p = 0.061); Charlson Comorbidity Index > 3 (OR = 4.57; p < 0.001); a non-HIV co-infection (OR = 1.80; p = 0.013); other risk factors (OR = 5.70; p < 0.001); bowel perforation (OR = 70.30; p < 0.001); or acute renal failure (OR = 1.95; p = 0.001). In those with Salmonella as Main Diagnosis, among all complications, bowel perforation presented the strongest association with death outcome. Clinical practice guidelines can help to identify patients at risk of bowel perforation to reduce the fatality of the disease.

[Causes of hospital admission and morbidity according to gender identity in the Autonomous Community of Madrid].

The objective was to identify differences in health between transgender (trans) and cisgender (cis) people using the hospital discharge survey from the Autonomous Community of Madrid. Their characteristics, causes of admission and morbidities were described, comparing them by prevalence ratio and confidence interval (95% CI). One hundred and twelve trans vs 1,043,621 cis discharges were studied. The main differences were that more frequently trans people had been attended in a single center (55.4 vs. 9.3%), were under 49 years old (75.9 vs. 37.1%) and had used private health services (2.7 vs. 0.4%). Admissions related to mental health problems (23.96; 95% CI: 17.41-32.78) and HIV morbidity (11.26 95% CI: 5.46-20.93) were more frequent among trans discharges. Information is limited beyond body modification, mental health, and HIV. It is necessary to improve the knowledge about trans population's health.

Added sugars and ultra-processed foods in Spanish households (1990-2010).

BACKGROUND/OBJECTIVES: To study the association between ultra-processed foods acquisitions and added sugar content of total food purchases in Spanish households in 2010. Changes over time (1990-2000-2010) in ultra-processed food purchases and added sugars content of total food purchases are also compared. SUBJECTS/METHODS: We used data from three nationally representative Household Budget Surveys (HBS) conducted in 1990, 2000 and 2010. Number of studied households was 21,012, 33,730 and 22,116, respectively. Purchased foods and drinks were classified according to NOVA food groups as ultra-processed foods, processed foods, unprocessed or minimally processed foods, or processed culinary ingredients. Linear and Poisson regressions were used to estimate the association between quintiles of energy contribution of ultra-processed foods and added sugars contents of total food purchases in 2010. Changes over time were assessed using tests of linear trend and Student's t test. RESULTS: In 2010, ultra-processed foods represented 31.7% of daily energy acquisitions and 80.4% of all added sugars. Added sugars content of food purchases raised from 7.3% in the lowest to 18.2% in the highest quintiles of energy contribution of ultra-processed foods. The risk of exceeding 10% energy from added sugars quadrupled between the lowest and highest quintiles. The percentage of ultra-processed foods on all food purchases almost tripled between 1990 and 2010 (from 11.0 to 31.7%), paralleling the increase of added sugars content (from 8.4 to 13.0%). CONCLUSIONS: Cutting down exceeding added sugars availability in Spain may require a reduction in ultra-processed food purchasing.

Effectiveness of acellular pertussis vaccine and evolution of pertussis incidence in the community of Madrid from 1998 to 2015.

INTRODUCTION: Pertussis is a communicable disease that primarily affects infants. Vaccination has led to an important reduction in the incidence of the disease, however, resurgence of the disease has been observed. This study aimed to analyze the incidence of pertussis and assess the vaccination effectiveness (VE) of different schedules of acellular pertussis vaccination in the community of Madrid. METHODS: Pertussis cases notified to the Mandatory Disease Reporting System from 1998 to 2015 were analyzed. Five comparison periods were created: 1998-2001 (reference), 2002-2005, 2006-2009, 2010-2012 and 2013-2015. The incidence ratio (IR) between inter-epidemic periods was analyzed using a Poisson regression. VE was calculated using the screening method. Vaccine status data were collected from the vaccine registry. RESULTS: In total, 3855 cases were notified. Inter-epidemic periods were observed every 3-4 years. The incidence increased (IR: 5.99, p < 0.05) in the 2013-2015 period, particularly among infants younger than 1 month (IR: 32.41, p < 0.05). Vaccination data were available in 89% of cases. For those receiving the last dose at ≤6-month VE was 89.9% (95% confidence interval (CI): 87.3-92.0) after one year of follow-up, and 85.5% (95% CI: 82.4-88.1) after 11 years of follow-up. For those receiving the last dose at 18-months VE decreased from 98.8% (95% CI: 98.3-99.1) to 85.1% (95% CI: 81.9-87.7) in the same period, and for those receiving the last dose at 4-year VE decreased from 99.6% (95% CI: 99.3-99.7) to 79.3% (95% CI: 74.6-83.1). CONCLUSIONS: B. pertussis is circulating in our population, as shown by the epidemic peaks and increased incidence of pertussis in recent years. VE increased with the number of doses and decreased with the follow-up period. The effect of this and other vaccination strategies must be monitored to control the disease.

Effectiveness of different vaccine schedules for heptavalent and 13-valent conjugate vaccines against pneumococcal disease in the Community of Madrid.

INTRODUCTION: The heptavalent pneumococcal conjugate vaccine (PCV-7) was added to the childhood routine vaccination program in the Community of Madrid in November of 2006 with 3+1 recommended doses and a catch-up for those under 2years old. In June 2010, PCV-7 was replaced by 13-valent vaccine (PCV-13) with 2+1 recommended doses. In July of 2012, the PCV-13 was removed from the funded program and reintroduced again (2+1 recommended doses) in December 2014. In between, children were vaccinated privately with 3+1 recommended doses of PCV-13. The aim of this study was to evaluate the effectiveness of each vaccination schedule used in the Community of Madrid. METHODS: We included all cases of invasive pneumococcal disease (IPD) reported between 2007 and 2015 to the Notifiable Diseases Surveillance System. Vaccination information was obtained from the Immunization Registry. Vaccine effectiveness (VE) was estimated using the indirect cohort design for cases with serotype information. RESULTS: A total 779 cases were included in the study. Among them 47.6% of the cases were primo-vaccinated with booster, 20% primo-vaccinated, 15.9% incompletely primo-vaccinated and 16.5% not vaccinated. The VE for ≥1 doses of any PCV was 82% (CI 95%: 67.8-89.9%): 91.9% (CI 95%: 76.5-97.2%) for PCV-7 and 77.2% (48.6-89.9%) for PCV-13. VE in those receiving the full 2+1 or 3+1 schedules was 100% for both vaccines. CONCLUSIONS: A high number of vaccine failures were reported in children before they had the opportunity to receive the booster dose, especially due to PCV-13-non-PCV-7 serotypes. VE was higher for PCV-7 compared to PCV-13, except for those that received the complete schedule with booster that achieved 100% of VE, which shows the relevance of the vaccines and complying with all doses scheduled.

[Trends and social inequalities in cervical cancer and breast cancer screening in Madrid: Non-Commumicable Disease Risk FactorSurveillance System (SIVFRENT-A) from 1995 to 2010]. / Tendencias y desigualdades sociales en el cribado de cáncer de cérvix y cáncer de mama en la Comunidad de Madrid duranteel periodo 1995-2010 a partir del Sistema de Vigilancia deFactores de Riesgo de enfermedades no transmisibles (SIVFRENT-A).

BACKGROUND: The assessment of preventive programs is necessary to support the decisions made in public health. There are few research studies that evaluate the degree of implementation and equity of cancer screening in Spain. The objective was to describe trends and inequalities in cervical and breast cancer screening according social determinants of health. METHODS: An analysis was carried out on the Behavioral Risk Factor Surveillance System of Community of Madrid data, obtained between 1995 and 2000 from telephone surveys conducted on a population between ages 18 to 65, were analyzed. The years were grouped into four periods: P1 to P4. The trends were estimated with prevalence ratios (PR) with 95% confidence intervals (95% CI), obtained through generalized linear models with binomial family and logarithmic link. The inequalities were estimated with differences of proportions (DP) with 95% CI. RESULTS: An increased in mammograms is seen especially in women with low education (PR P4/P1: 1.93; 95%CI 1.62 to 2.3), this trend more discreet in cytology (PR P4/P1: 1.28; 95%CI 1.11 to 1.47). However mammograms have not increased over in the past 5 years (PR P4/P3: 1.02; 95% CI 0.99 to 1.04). Inequalities get better, but show an increase in the last period. CONCLUSIONS: All groups increase in preventative behaviors and those who did not, had a high prevalence from the start.Itis worth mentioning the stagnation of mammography in disadvantaged women in the period 2007-2010. There was a social gradient for preventive preventative measures, which was lower in the population-basedscreening (mammography) than in the opportunistic one (cytology).
