RESUMO
BACKGROUND: To analyze hospitalization episodes with an ICD-9 diagnosis code of influenza (codes 487 and 488) in any diagnostic position from 2009 to 2015 in the Spanish hospital surveillance system. METHODS: Information about age, length of stay in hospital, mortality, comorbidity with an influenza diagnosis code between 1 October 2009 and 30 September 2015 was obtained from the National Surveillance System for Hospital Data (Conjunto Mínimo Básico de Datos, CMBD). RESULTS: 52,884 hospital admissions were obtained. A total of 24,527 admissions corresponded to diagnoses ICD-9 code 487 (46.4%), and 28,357 (53.6%) corresponded to ICD-9 code 488. The global hospitalization rates were 8.7 and 10.6 per 100,000 people, respectively. Differences between the two diagnostic groups were found for each of the six analyzed seasons. The diagnostic ICD-9-CM 488, male gender, and high-risk patients classified by risk vaccination groups showed direct relationship with inpatient hospital death. CONCLUSIONS: Influenza diagnosis was present in a significant number of hospital admissions. The code used for diagnosis (ICD-9-CM 488), male sex, age groups and associated risk clinical conditions showed a direct relationship with inpatient hospital fatality.

We report on trends in anaphylaxis admissions in the Spanish hospital system during the period 1998-2011. Data on admissions for anaphylaxis were obtained from the Spanish Information System for Hospital Data for the period 1998-2011. Patients were selected using the codes for anaphylaxis in the International Classification of Diseases, Ninth Revision, Clinical Modification (ICD-9-CM). Poisson regression models were used to estimate incidence rate ratios. We recorded a 1.89-fold increase in admissions for anaphylaxis in Spanish hospitals during the study period, particularly in patients aged 0-14 years (1.65- to 3.22-fold until 2009 and 4.09- to 12.59-fold until 2011) and in food anaphylaxis in all age groups (2.78-fold until 2009 and 8.74-fold until 2011). The incidence of anaphylaxis is perceived as having increased in recent years, especially anaphylaxis caused by food and anaphylaxis affecting the pediatric population.

BACKGROUND: Despite the reduction in the incidence of measles in recent years, outbreaks have appeared in various countries in Central and Western Europe. Estimating the percentage of immune individuals is fundamental for establishing control strategies in these situations. METHODS: A total of 1,147 serum samples from healthy volunteers were tested by two commercial enzyme immunoassay (EIA) tests that detect antibodies for the measles virus: Enzygnost Anti-Measles Virus/IgG (Siemens, Marburg, Germany) and VIDAS Measles IgG (bioMerieux, Inc.). The following values were calculated for each test: sensitivity, specificity, positive and negative predictive values, and likelihood ratios. RESULTS: Compared to the Enzygnost test, the sensitivity of the VIDAS test was 98.0% and the specificity was 78.1%. The likelihood ratio (LR) values were + 4.48, - 0.025 and +/- 0.17. CONCLUSIONS: The VIDAS Measles IgG test is a quick method with good sensitivity for detecting IgG antibodies for the measles virus compared to the Enzygnost EIA test.

OBJECTIVE: To analyse the epidemiology of suicide, and compare its occurrence between the sexes and in various regions in Spain. METHOD: Age-specific analysis and spatiotemporal analysis to analyse death by suicide between 1981 and 2008 in Spain. STUDY DESIGN: Ecological study. RESULTS: Death by suicide has decreased since the 1990s in Spain, although peaks in suicides correspond with times of economic crisis. Death by suicide was more common among men than among women, although the suicide mortality rate increased over the study period among women aged 35-49 years. Geographical analysis showed that rural populations and areas with historically higher levels of unemployment have higher suicide rates. In contrast, less-populated regions have lower suicide rates. CONCLUSION: Suicides in Spain exhibit a clear geographic pattern and occur at different rates between the genders. The results suggest an increasing number of suicides among women aged 35-49 years over the study period.

OBJECTIVES: In recent years, the incidence of breast cancer has increased in Spain but mortality has decreased, particularly since 1992. Despite the general decrease in mortality, the intensity of this disease differs between age groups. The main objective of this study was to examine mortality due to breast cancer for different age groups in Spain from 1981 to 2007, and to forecast the mortality rate in 2023. STUDY DESIGN: Ecological study. METHODS: Trends in mortality due to breast cancer were analysed using the Lee-Carter model, which is the typical analysis for mortality in the general population but is rarely used to analyse specific causes of death. RESULTS: This study found a decreasing trend in mortality due to breast cancer from 1993 to 2007, and it is predicted that this trend will continue. However, mortality rates varied between age groups: a decreasing trend was seen in younger and middle-aged women, whereas mortality rates remained stable in older women. CONCLUSIONS: Preventive breast cancer practices should differ by patient age.

In this article, we will review the main vaccination strategies currently being implemented by the health authorities and analyze the main vaccines authorized by the EMA. As practical aspects of vaccination, we must make it clear that until collective immunity is reached, the preventive measures being implemented will have to be kept in place. In the words of the WHO Accelerator Project, There is no time to waste in the fight against COVID-19. No one is safe until everyone is safe.

We describe the most widely used temporary hospital in Europe during the first pandemic wave, its structure, function, and achievements. Other models of care developed during the pandemic around the world were reviewed including their capacity, total bed/ICU bed ratio and time of use. We particularly analyzed the common and differential characteristics of this type of facilities. IFEMA Exhibition Center was transformed into a temporary 1,300-bed hospital, which was in continuous operation for 42 days. A total of 3,817 people were treated, generally patients with mild to moderate COVID-19, 91% of whom had pneumonia. The average length of stay was 5 to 36 days. The most frequent comorbidities were hypertension (16.5%), diabetes mellitus (9.1%), COPD (6%), asthma (4.6%), obesity (2.9%) and dementia (1.6%). A total of 113 patients (3%) were transferred to another centers for aggravation, 19 (0.5%) were admitted to ICU and 16 patients (0.4%) died. An element of great help to reducing the overload of care in large hospitals during peaks of health emergencies could be these flexible structures capable of absorbing the excess of patients. These must be safe, breaking domestic transmission and guarantee social and emotional needs of patients. The success of these structures depends on delimitation in admission criteria taking into account the proportion of patients who may require, during admission, assistance in the critical care area.

OBJECTIVE: The diagnosis of SARS-CoV-2 infection is crucial for medical and public health reasons, to allow the best treatment of cases and the best control of the pandemic. Serology testing allows for the detection of asymptomatic infections and 19-COVID cases once the virus has been cleared. We analyzed the usefulness of the SARS-CoV-2 rapid test of Autobio and tried to correlate its pattern with the severity of COVID19 infection. METHODS: We analyzed the accuracy and clinical usefulness of a point-of-care IgM and/or IgG test for SARS-CoV-2 in 35 COVID-19 patients [12 (34.3%) mild-moderate and 23 (65.7%) severe-critical] admitted to a field hospital in Madrid, as well as in 5 controls. RESULTS: The mean time from the first day of symptoms to the antibody test was 28 days (SD: 8.7), similar according to the severity of the disease. All patients with SARS-CoV-2 PCR+ showed the corresponding IgG positivity, while these results were negative in all control individuals. A total of 26 (74%) cases also presented with positive IgM, 19 (83%) were severe-critical cases and 7 (58%) were mild-moderate cases. The IgM response lasted longer in the severe critical cases (mean: 29.7 days; SD: 8.4) compared to the moderate cases (mean: 21.2 days; SD: 2.0).. CONCLUSIONS: Rapid serology tests are useful for the diagnosis of patients with COVID-19 (mainly IgG detection) and may also be correlated with the severity of the infection (based on IgM detection).

INTRODUCTION: Serum vitamin B12 concentration levels in children are essential to establish values in order to compare different regions or countries, and for considering e the possibility of supplementing diets with group B vitamins as a secondary prevention against cardiovascular diseases. MATERIAL AND METHODS: A cross-sectional epidemiological study was carried out to asses serum vitamin B12 levels in school children, 13-15 years of age, in Madrid. Folate and vitamin B12 vitamin determinations were performed on fasting blood samples. Genotype C677T of methylentetrahydrofolate reductase (MTHFR) enzyme was determined by PCR. RESULTS: The mean vitamin B12 level obtained in our study was 503 pmol/l; CI 95 % CI (478-528 pmol/l). The median was 471 pmol/l; interquartile range (IR) (337-632 pmol/l). No statistically significant differences were found by age or C677T genotype for MTHFR. Serum vitamin B12 concentrations were significantly higher in females. Prevalence of vitamin B12 deficiency (< 224 pmol/l) was 6 % in males and 4 % in females. CONCLUSIONS: Reference values for serum vitamin B12 concentrations in an adolescent population are presented. Prevalence of vitamin B12 deficiencies is higher in males.

OBJECTIVES: This study aimed to estimate total and age-specific incidence rates of HZ with data from electronic clinical records in primary care (ECRPC) and to analyze trends by sex and age. METHODS: Descriptive cross-sectional study covering the incident HZ episodes registered in the ECRPC of the Madrid Regional Public Health System in 2005-2012. Annual crude and age-adjusted incidence rates were calculated. Differences by sex and age were assessed by poisson regression. The annual percentage of change (APC) of incidence rates and 'breakthrough points' of the time trends were determined with the Joinpoint Regression Program. RESULTS: 211,650 episodes of HZ were identified (60.6% women, 52.2% > 55 years). The incidence rate increased from 363.21 to 481.92 per 100,000 person-year in 2005-2012. Rates were higher among women and increased with age. The APC for the period was 3.59% in men and 3.67% in women (p < 0.05). Age-specific rates increased in patients over 14 years. The APC in the 25-44 age group was 7.4% since 2007. The incidence rate ratio (women/men) was highest in this group. CONCLUSIONS: The incidence of HZ presents an upward trend in 2005-2012 in adults and the elderly. Monitoring the incidence and age-specific rates, will help to detect changes in trends.

BACKGROUND: Pancreatic cancer is one of the least common tumours, nevertheless it is one of the most lethal. This lethality is mainly due to the fact that the vast majority of patients are diagnosed in an advanced stage. The purpose of this study was to investigate how different covariates affect the transition to death or discharge with and without complications after pancreatic resection. METHODS: We analyse the impact of different factors on transitions after pancreatic resection based on a multi state model. RESULTS: Transitions of interest include the transition to death/discharge with/without complications after pancreatic resection. We consider presence of comorbidities, higher age (>60), gender-male, lower hospital volume (<10 cases per year), type of surgery, localization of tumour and transfusion received as covariates with a potentially negative effect on the transition intensities to death with or without complications. CONCLUSIONS: The multi-state model allows for a very detailed analysis of the impact of covariates on each transition, since effects of covariates may change depending on the current state of the patient, thus helping surgeons and patients throughout the surgical process and counselling patients if needed.

Pancreatic cancer is one of the least common tumors (2.1%), but it remains one of the most lethal. This lethality is primarily due to late stage diagnosis in the vast majority of patients. Here we demonstrate, using a Bayesian network, that we can determine a posteriori, with a high probability of success, the probability of in-hospital death of pancreatic cancer in hospitals across Spain with information related to the type of admission, the type of procedure, the primary diagnosis or the Charlson co-morbidity index. The advantages of using a Bayesian network are that it allows us to examine multiple hypotheses and to measure the effect of the introduction of variables on our hypotheses. Being able to determine deceases in the probability of survival based on hospital admission data, such as the diagnosis resulting in the present admission or the presence of co-morbidities, could facilitate the detection of deficiencies in the patient treatment and improve hospital management. Moreover, the control of related co-morbidities may have an impact on the in-hospital deaths of these patients.
RESUMO
BACKGROUND: Rubella is benign in children, but in pregnant women it can produce Congenital Rubella Syndrome (CRS) with severe consequences for the foetus. In spite of vaccination coverage in Spain being above 95%, isolated cases and outbreaks continue to occur. The aim of this study is to estimate the incidence of hospitalisations due to rubella in Spain (1997-2006). METHODS: Utilising the basic minimum dataset (National System of Epidemiological Surveillance) we calculated: rate of hospitalisation, average stay and cost. RESULTS: There were 267 hospitalisations, amongst them 144 due to rubella during pregnancy, 1 due to CRS and 8 due to encephalomyelitis. The overall rate of hospitalisation was 0.065 per 105 inhabitants (IC95%=0.0649-0.0654). The average stay was 3 days. The average cost of a hospitalisation was 2,082 euros, and if complicated by encephalomyelitis it rose to 8.191 euros. CONCLUSION: There continue to be hospitalisations due to rubella, basically due to problems in gestation and to complications in the existing susceptible population group.

The burden of hospital admissions for pneumococcal meningitis in pediatric population in Spain during a 9-year period was estimated. Data were obtained from the national information system (computerized hospital discharge data). There were 770 hospital admissions with an annual incidence of 1.44 cases per 100,000 population. Rate of death and case-fatality rate were 0.11 per 100,000 population and 7.92%, respectively. The higher incidence and rate of death was found in children up to 12 months of age and the higher case-fatality rate in children of 10-14 years of age. Further studies assessing the incidence of pneumococcal meningitis in post-vaccination period are needed.
