Socioeconomic inequalities in unintended pregnancy and abortion decision.

Pregnancy planning allows women to better control their life trajectory and contributes to the future child’s health and development. Many studies that have analyzed socioeconomic inequalities in unintended pregnancy only took into account those pregnancies ending in births. Few of them that analyzed unintended pregnancy, including both induced abortion and births, and its socioeconomic determinants, concluded that unintended pregnancy is more frequent in young, poor, or unmarried women. These inequalities have been poorly studied in Europe, especially in the southern European context. The aim of the present study is to describe socioeconomic inequalities in unintended pregnancy and in abortion decision in Barcelona, Spain. The major findings are that unintended pregnancies accounted for 41% of total pregnancy and of these, 60% ended in abortion. From all pregnancies, the proportion of induced abortion reached 25.6%. Compared to women with university studies, those with primary education uncompleted had more unintended pregnancies (OR = 7.22). When facing an unintended pregnancy, women of lower socioeconomic position are more likely to choose induced abortion, although this is not the case among young or single women. This study reveals deep socioeconomic inequalities in unintended pregnancies and abortion decision in Barcelona, Spain, where the birth rate is very low and the abortion rate is rising. Women in low socioeconomic positions have many more unintended pregnancies than better educated women. Except for young or single women, the lower the socioeconomic position, the higher the proportion of women who choose an induced abortion when facing an unintended pregnancy.

Análisis de la tendencia en la letalidad, incidencia y mortalidad por infarto de miocardio en Girona entre 1990 y 1999

Introduccion y objetivos La incidencia por infarto de miocardio en Espana es baja y la mortalidad esta disminuyendo en las ultimas decadas. Hemos analizado las tendencies en las tasas de mortalidad, incidencia y ataque, y en la letalidad a 28 dias por infarto de miocardio entre 1990 y 1999 en la poblacion de 35 a 74 anos de Girona. Metodos Se incluyeron todos los casos de infarto de miocardio de Girona clasificados segun el algoritmo MONICA. Se calcularon las tasas de ataque, incidencia y mortalidad, y la letalidad, asi como el porcentaje de cambio annual en cada uno de los indicadores durante el periodo analizado. Resultados La tasa anual media de ataque fue de 258 (intervalo de confianza [IC] del 95%, 249-267) y 55 (IC del 95%, 51-59) por 100.000 habitantes para varones y mujeres, respectivamente, y la de mortalidad de 99 (IC del 95%, 93-104) por 100.000 en varones y de 25 (IC del 95%, 22-28) por 100.000 en mujeres. Las tasas de ataque, incidencia y recurrencia disminuyeron significativamente en varones de 35 a 64 anos durante el periodo 1990-1999, pero no en los de 65 a 74 anos ni en las mujeres. Conclusiones La incidencia y la mortalidad por IAM fueron bajas en la poblacion de 35 a 64 anos, y mejoraron en los varones de 35 a 64 anos durante el periodo 1990-1999, pero no en los de 65 a 74 anos, lo que indica que la combinacion de prevencion primaria y secundaria ha retrasado la edad de aparicion del infarto de miocardio o de las recurrencias. Las tasas en mujeres fueron inferiors y no cambiaron durante el periodo estudiado.

Validación de la causa básica de defunción en las muertes que requieren intervención medicolegal

Background: Deaths due to external causes require additional medical tests in order to determine the cause of death. If these results are not incorporated into the death register these causes may be misclassified. The objective of this study is to validate the underlying cause of death of the Mortality Register with information obtained from forensic sources in Barcelona between 2004 and 2006. Methods: Cross-sectional design. The study population consisted of deceased residents in Barcelona with a medicolegal intervention between 2004 and 2006. The sources of information are the Mortality Registry and the forensic pathology file filled in by Institute of Legal Medicine of Catalonia (ILMC) (gold standard). The study variables are the cause of death, sex and age. Sensitivity and percentage of confirmation (PC) with 95% confidence intervals (95% CI) are calculated. Results: The sensitivity of external causes is 59.7% (95% CI:56.5-62.9) and PC is 96.7% (95% CI:94.8-98.0). Traffic injuries, poisonings and suicides are under-reported in the Mortality Register with a sensitivity lower than 45% and a PC higher than 80%. Symptoms, signs and ill-defined conditions are over-reported with a sensitivity of 89.2% (95% CI:83.4-93.4) and a PC of 28.0% (95% CI:24.2-32.1). There are no differences by sex and age. Conclusions: The validity of the external causes in the Mortality Register is low due to under-reporting and the high proportion of symptoms signs and ill-defined causes. According to the results, incorporating information from forensic sources to the Mortality Register increases the quality of mortality statistics.BACKGROUND Deaths due to external causes require additional medical tests in order to determine the cause of death.

Perceived Sexism as a Health Determinant in Spain

OBJECTIVES The goals of the present study are to explore the association between perceived sexism and self-perceived health, health-related behaviors, and unmet medical care needs among women in Spain; to analyze whether higher levels of discrimination are associated with higher prevalence of poor health indicators and to examine whether these relationships are modified by country of origin and social class. MATERIALS AND METHODS The study is based on a cross-sectional design using data from the 2006 Spanish Health Interview Survey. We included women aged 20-64 years (n = 10,927). Six dependent variables were examined: four of health (self-perceived health, mental health, hypertension, and having had an injury during the previous year), one health behavior (smoking), and another related to the use of the health services (unmet need for medical care). Perceived sexism was the main independent variable. Social class and country of origin were considered as effect modifiers. We obtained the prevalence of perceived sexism. Logistic regression models, adjusted for potential confounders, were fitted to study the association between sexism and poor health outcomes. RESULTS The prevalence of perceived sexism was 3.4%. Perceived sexism showed positive and consistent associations with four poor health outcomes (poor self-perceived health, poor mental health, injuries in the last 12 months, and smoking). The strength of these associations increased with increased scores for perceived sexism, and the patterns were found to be modified by country of origin and social class. CONCLUSION This study shows a consistent association between perceived sexism and poor health outcomes in a country of southern Europe with a strong patriarchal tradition.

Myocardial infarction in Girona, Spain: Attack rate, mortality rate and 28-day case fatality in 1988

This study was conducted to establish the attack rate, mortality rate and 28-day case-fatality rates of acute myocardial infarction (AMI) occurring in Girona, Spain, between October 1987 and September 1988. The study was carried out using a population register of AMI, and took place in one central hospital, and eight county hospitals in Girona (in the autonomous community of Catalonia, northeast Spain). Subjects comprised 222 fatal cases selected from 4069 death certificates, and 210 non-fatal cases from hospital records, among subjects aged between 25 and 74 years (reference population 263,778). The age standardized attack rate was 105.6 per 100,000 inhabitants in the age group 35-64 (193.6 in men and 17.6 in women). The age standardized mortality rate was 36.3 per 100,000 inhabitants in the age group 35-64 (63.1 among men and 9.9 among women). The age standardized 28-day case-fatality was 34.6% in men and 50.1% in women in this same age group. Attack and mortality rates of AMI in a region of Spain are presented for the first time. These rates are lower than in other developed countries, nevertheless the 28-day case-fatality is similar to that of these countries.

Oral Health-Related Quality of Life in institutionalized elderly in Barcelona (Spain)

Objective: The objective of this study is to describe the oral health status and the factors associated with oral health-related quality of life (OHRQoL) in people aged 65 and older institutionalized in Barcelona in 2009. Study Design: Cross sectional study in 194 elderly. The dependent variable was poor OHRQoL, according to the Geriatric Oral Health Assessment Index (GOHAI). The independent variables were socio-demographic data, last dental visit, subjective and objective oral health status. Robust Poisson regression analysis was used to determine the factors associated with OHRQoL as well as the strengths of association (Prevalence Ratios with respective confidence intervals at 95%). Results: According to GOHAI, 94 women (68.1%) and 36 men (64.3%) had poor OHRQoL. The average DMFT index (number of decayed, missing and filled teeth) was 22.8, with mean 10.2 remaining teeth. According to the Community Periodontal Index only 1.9% were healthy. 33.8% of the sample (35.5% of women and 30.4% of men) presented edentulism, 54.2% needed upper dental prostheses (51.1% of women and 60.7% of men) and 64.7% needed lower ones (61.6% of women and 71.4% of men). Only 7.2% had visited a dentist in the past year (8.8% of women and 3.6% of men). After fitting several multivariate adjusted robust Poisson regression models, poor OHRQoL was found to be associated to self-reporting problems with teeth or gums, self-reporting poor opinion about teeth/gums/denture and also associated to functional edentulism, needing upper denture, but not to socio-demographic factors or time since last dental visit. Conclusions: The study population has poor objective oral health. A high percentage has poor OHRQoL associated to subjective and objective oral health conditions. Dental care is required and these services should be included in the Spanish National Health System. Key words:Oral health, homes for the aged, elderly, self-assessment, quality of life, geriatric oral health assessment index (GOHAI).

Invasive Cells in the Placentome of Andean Populations of Mabuya: An Endotheliochorial Contribution to the Placenta?

New world lizards of the genus Mabuya have the most specialized level of placentotrophy among reptiles known to date, and related to that, they have the most complex allantoplacenta characterized by a series of morphological specializations that converge with those known for eutherian mammals. One of these specializations is the placentome that is found in the embryonic pole of the incubation chamber. In the mature allantoplacenta, this structure is morphologically the most complex, which could support an important amount of nutrient exchange between mother and fetus. According to the relationship between the chorioallantois and the syncytial uterine epithelia, the placenta of Mabuya populations shows some interesting similarities to the synepitheliochorial type. Recently, cells of chorionic origin have been found invading the syncytial uterine epithelium, and in very close proximity with uterine blood vessels. In this study, we describe the relationship between these invasive chorionic cells, the uterine syncytium, and the subjacent blood vessels of several populations of this genus, by means of high resolution optical microscopy and transmission electron microscopy. Cell groups originating from the chorion, of variable size and shape, penetrate the uterine syncytial epithelium extending complex cytoplasmic projections that come in contact with uterine capillaries and form an extensive and complex double‐membrane system that surrounds the capillary. The close relationship between the chorion and the maternal circulation suggests that the Mabuya placentome shows some characteristics of an endotheliochorial placenta. This finding constitutes so far the only documented example of an endotheliochorial placentation in Reptilia. Anat Rec, 2007.

Morphology of the male reproductive duct system of Caiman crocodilus (Crocodylia, Alligatoridae).

The male reproductive duct system of Caiman crocodilus in different reproductive stages was studied using light and electron microscopy, to determine whether shared morphological features exist between Crocodylia and Aves, in concurrence with the Archosauria hypothesis. The sexual duct system of Caiman crocodilus is constituted of the rete testis, ductuli efferentes, ductuli epididymides, ductus epididymidis, and ductus deferens. The morphology and histochemical properties of these ducts suggest their involvement in seminal fluid production and/or its modification. Three types of non-ciliated cells were identified along the duct system. 1. The noncliated cells of the ductuli efferentes contain electron dense worm-like structures and coated vesicles, both related to absorptive processes, as has been suggested in Aves. 2. The non-ciliated cells of the ductuli epididymides have apical electron dense granules suggesting a secretory role, and 3. The non-ciliated cells of the ductus epididymidis and ductus deferens did not exhibit conspicuous storage of secretory material, but have a prominent rough endoplasmic reticulum content indicating active protein production. The occurrence of abundant secretory granules in the epithelial cells of the distal ductus deferens during non-reproductive stages suggests its participation in the removal of luminal debris when the reproductive season ends. Additional ducts were observed running along the ductus deferens; they shared morphological characteristics with the ductuli epididymides. The maximum diameter and therefore the greatest sperm accumulation of the excurrent ducts were observed during the initial testicular regression. The comparative analysis suggests that the male reproductive system of the Crocodylia exhibits structural characteristics nearer to those of Aves than to Lepidosauria, Testudines, and Mammalia, additional data that support an Aves and Crocodylia sister group relationship.

Interval from diagnosis to treatment onset for six major cancers in Catalonia, Spain

BACKGROUND Targets set by health care organizations on time intervals between cancer diagnosis and treatment often go unmet. The objective of the study was to analyse the interval from diagnosis to treatment onset, and related factors, in the six most incident cancers in Catalonia (Spain), a developed European region with universal free access to health care. METHODS Twenty-two hospitals contributed 1023 incident cancer patients (198 lung, 253 colorectal, 95 prostate, 109 urinary bladder, 266 breast, 102 endometrial). Information was gathered from hospital medical records. The dependent variable was the length of the diagnosis to treatment interval (DTI). Independent variables were age, sex, disease stage, hospital level, mode of admission to hospital, and type of physician seen before admission. Multivariate-adjusted odds ratios were calculated by unconditional logistic regression for each cancer site. RESULTS The median DTI (in days) was 39 for lung cancer, 25 for colorectal, 108 for prostate, 69 for bladder, 35 for breast and 40 for endometrial cancer. In prostate and bladder cancers, over 78% of patients showed a DTI >30 days, while in colorectal the figure was 42%. Disseminated stage (distant metastases) was associated with a lower DTI in all sites. Patients admitted to third-level hospitals and with an elective admission were more likely to have a DTI >30 days. CONCLUSIONS In Catalonia, a substantial proportion of cancer patients experience treatment delays that may impact negatively on psychological well-being, quality of life, and probably survival as well.
