Assessing the influence of working hours on general health by migrant status and family structure: the case of Ecuadorian-, Colombian-, and Spanish-born workers in Spain.

OBJECTIVES: The purpose of this study was to analyze the relationship between working hours (WHs) and the likelihood of poor self-reported general health (SRGH) in the first data wave from a cohort of immigrant and native workers in Spain. STUDY DESIGN: Cross-sectional analyses from a prospective cohort study. METHODS: Data were drawn from the first wave of the Platform of Longitudinal Studies on Immigrant Families. The selected sample was composed of 217 immigrant workers and 89 native-born workers. We explored differences by immigrant status and family structure, assessing prevalences and Poisson regression models; an additional analysis explored statistically optimized work hour cut points. RESULTS: Highest prevalence of poor SRGH (72.7%) was reported by immigrant, single-parent workers working >40 WH/week. Immigrant single-parent families were more likely to report poor SRGH for three WH categories: ≤20 WH/week (prevalence ratio [PR] = 3.3, 95% confidence interval [CI] 1.6-7.2), >30-≤40 WH/week (PR = 2.8, 95% CI 1.3-6.4), and >40 WH/week (PR = 4.2, 95% CI 1.8-10.1). In two-parent families, immigrants working standard hours (i.e. >30-≤40) and native-born workers in the highest and lowest categories of WHs (i.e. ≤20 and >40) had similar PRs for poor SRGH compared with native-born workers working standard hours. Findings suggested that native-born workers residing in two-parent families were able to work more than 10 h longer per week than immigrant workers before reporting equivalent prevalences of poor SRGH. CONCLUSIONS: Differences in the association of WHs and poor SRGH among immigrants in Spain seem to be explained by family structure, which suggests that the influence of WHs on health differentially affects vulnerable groups, such as immigrant workers residing in single-parent families.

Different natures of surface electronic transitions of carbon nanoparticles.

The photoluminescence behaviour of carbon-based nanodots is still debated. Both core and surface structures are involved in the emission mechanism, and the electronic transitions can be modified by external agents such as metal ions or pH, but the general relation between the structure and the optical function is poorly understood. Here, we report a comparative study on the effects of these variables, changing the core structure from crystalline to amorphous, and modifying the surface structure by different passivation procedures. Our results highlight that the emission mechanism of the tunable visible fluorescence is identical for crystalline and amorphous samples, indicating the independence of the emission from the core structure. Furthermore, surface functionalization weakly influences the emission peak position, but has large consequences on their interaction with different metal ions. This suggests the involvement of quasi-degenerate electronic states originating from the high density of different interacting groups on the surface. Finally, we report the presence of an unusual ultraviolet emission band for the amorphous sample, likely involving localized molecular-type chromophores with carboxyl ends. Our findings provide new information on the emission mechanisms of CDs and can be used to engineer sub-types of CDs displaying very similar emission features, but specifically tailored for different sensing applications.

Effect of CYP2C19 Polymorphisms on the Platelet Response to Clopidogrel and Influence on the Effect of High Versus Standard Dose Clopidogrel in Carotid Artery Stenting.

OBJECTIVES: Genetic background has been identified to be a major predictor of post-clopidogrel platelet inhibition in patients undergoing coronary stenting. However, there is a lack of data on clopidogrel response regarding genotype in patients undergoing carotid artery stenting (CAS). The influence of the most common allelic variants of CYP2C19 phenotypes and genotypes on response to baseline clopidogrel and on the pharmacodynamic effect of dose adjustment (high or standard dose of clopidogrel) in patients with high on-treatment reactivity after CAS was investigated. METHODS: Platelet reactivity was assessed before and 30 days after carotid stenting using the VerifyNow P2Y12 assay to obtain P2Y12 reactivity unit (PRU) values. RESULTS: A total of 209 patients (79.4% male, 44.1% currents smokers) were treated by CAS. Smokers improved responsiveness to clopidogrel (p = .034). With respect to CYP2C19 enzymatic function, 61 subjects (29.1%) were ultra-rapid metabolizers, 95 patients (45.5%) were extensive metabolizers, 51 (24.4%) were intermediate metabolizers, and two (0.96%) were poor metabolizers. Baseline PRU was significantly higher among intermediate-poor metabolizers compared with ultra-rapid (p = .001) or extensive metabolizers (p = .005). At 30 days follow up, in non-responding patients with the intermediate-poor metabolizer phenotype, the PRU value and inhibition percentage were significantly reduced with standard dose (p = .008; p = .0029) and high dose of clopidogrel (p = .00 0; p = .000). However, high dose clopidogrel did not achieve a more intense pharmacodynamic effect at 30 days (p = .994) compared with standard dose. CONCLUSIONS: In patients undergoing carotid stenting, those with the CYP2C19*2 allele had increased basal PRU values and in fact clopidogrel non-responders increased significantly among intermediate-poor metabolizers. Although high dose and standard dose clopidogrel therapy was effective in lowering the 30 day PRU values in patients with high on-treatment reactivity who are intermediate-poor metabolizers, the use of high dose clopidogrel did not result in statistically significantly greater reductions in reactivity compared with the standard dose.

Analysis of cerebrovascular mortality trends in Spain from 1980 to 2011. / Análisis de las tendencias en la mortalidad por enfermedades cerebrovasculares en España 1980-2011.

INTRODUCTION: In recent decades, mortality rates for cerebrovascular diseases (CVD) have declined significantly in many countries. This study analyses changes in CVD mortality rates in Spain (1980-2011) to determine if previously observed trends remain. PATIENTS AND METHODS: Data on CVD mortality rates and the population data needed for the analysis were provided by Spain's National Statistics Institute. We calculated age-specific mortality rate, age-standardised overall mortality, and age-truncated mortality (35-64 years) using the direct method and standard European population structure. Joinpoint analysis was used to estimate the percentage of annual change in rates and identify significant changes in trends. RESULTS: CVD mortality rate decreased considerably and continuously over the last 32 years in all age groups and in both sexes in Spain. For both sexes, joinpoint analysis identifies a final period with more marked decline: 2005-2011 in women (-6.3%) and 2007-2011 in men (-7.2%). CONCLUSIONS: CVD mortality rates displayed a marked and continuous decline in Spain between 1980 and 2011. Due to the ageing of the population, doctors expect an increase in CVD prevalence and therefore its magnitude in terms of disability and healthcare costs, which poses a challenge to our health system.

Geographical differences in chronic obstructive pulmonary disease mortality trends by sex, Spain, 1980-2021.

BACKGROUND: To analyse changes in trends in mortality due to chronic obstructive pulmonary disease (COPD) in Spain by Autonomous Community (AC) and sex during the period 1980-2021.METHODS: Data on population and COPD death records (International Classification of Diseases, 10th edition, codes J40â-"J44 and J47) were retrieved from the National Institute of Statistics for the study period. Age-standardised mortality rates by AC and sex were assessed using joinpoint regression models.RESULTS: There were 562,668 deaths due to COPD (423,855 in men and 138,813 in women), with an average annual increase of 1.6%. COPD deaths in men increased in most ACs, except for Asturias (â-"0.5% per year). The Canary Islands (14% per year) and Madrid (6.5% per year) had the highest increases. In women, the figures show a wide range of values at the AC level (from a â-"1.4% decrease to 7.9% increase). Nationally, the sex ratio increased from 1980 to 2021. In men, six ACs showed a significant decrease, while in women only two ACs showed a significant decrease.CONCLUSION: A steady decrease in COPD mortality was observed in most ACs for men, while a different trend was observed in women in several ACs. Despite past and ongoing tobacco control initiatives, this condition remains a leading cause of death.

Rising testicular cancer incidence in Spain despite declining mortality: an age-period-cohort analysis.

BACKGROUND: Testicular cancer, primarily affecting young men, has seen an alarming rise globally. This study delves into incidence and mortality trends in Spain from 1990 to 2019 using the Global Burden of Disease (GBD) database and the Age-Period-Cohort (A-P-C) model. METHODS: We analyzed GBD data on testicular cancer cases and deaths in Spain, calculating age-standardized rates (ASIR and ASMR) and employing Joinpoint regression to identify significant shifts. The A-P-C model further dissected the effects of age, period, and birth cohort on these trends. RESULTS: A striking doubling in testicular cancer incidence was observed, from 3.09 to 5.40 per 100,000 men (1.9% annual increase), while mortality rates remained stable and even decreased in younger age groups (0.34 to 0.26 per 100,000, 0.8% annual decrease). Joinpoint analysis revealed four distinct periods of increasing incidence, with a recent slowdown. The A-P-C model highlighted a consistent rise in incidence risk with each successive generation born after 1935, contrasting with a progressive decline in mortality risk across cohorts, particularly marked for those born since the 1960s. CONCLUSION: While mortality rates are encouraging, Spain reflects the global trend of escalating testicular cancer incidence. The A-P-C analysis suggests a generational influence, but the underlying causes remain elusive. Further research is crucial to understand these trends and implement effective prevention strategies to combat this growing health concern.

The influence of age, period, and cohort factors on the incidence of kidney cancer in Spain 1990-2019: Evidence from the global burden of disease study.

OBJECTIVE: This study aimed to assess the influence of age, period, and cohort (A-P-C) factors on kidney cancer (KC) incidence trends in Spain from 1990 to 2019. METHODS: Employing data from the Global Burden of Disease Study 2019, we employed joinpoint analysis to determine long-term patterns and A-P-C modelling to quantify net drift, local drift, longitudinal age curves, and rate ratios (RRs) of period and cohort effects. RESULTS: Over the period 1990-2019, an estimated 142,811 cases of KC were diagnosed in Spain. A consistent upward trend in KC incidence was observed for both men and women, with the male-to-female ratio remaining stable at 2.6. Joinpoint analysis identified three distinct periods for men: An initial period (1990-1995) characterised by a significant increase in rates, a subsequent period (1995-2016) characterised by a slowdown in the rate of increase, and a final period (2016-2019) in which rates have plateaued. In women, 2 time periods were observed: an initial period (1990-2007) in which rates increased significantly, followed by a period of stabilization (2007-2019). Men born in the early-mid 20th century had a rising KC risk, peaking in the 1960s. Women's risk rose steadily, peaking in the late 1990s. CONCLUSION: A-P-C analysis reveals steady KC incidence increase in both genders over three decades. This highlights the need for targeted public health policies and effective prevention strategies.

Bladder cancer mortality trends in Spain: 1980-2021.

OBJECTIVE: We propose to update bladder cancer mortality rates in Spain from 1980 to 2021, by sex and age-group, by autonomous community (AC). MATERIALS AND METHODS: The public online databases of the National Statistical Institute were used to obtain data on population and bladder cancer mortality. Age-standardised mortality rates (ASMRs), all ages and truncated (<75 and ≥75) were estimated and reported as rates per 100,000 persons. Joinpoint regression software was used for estimation and trend analysis of ASMRs bladder cancer. RESULTS: In the last decade, the ASMR for bladder cancer (all ages, <75 years and ≥75 years) decreased significantly in Spain for both sexes. This trend was observed in 12 ACs for men and in 4 ACs (Andalusia, Canary Islands, Catalonia and Madrid) for women, although to different degrees. For men, ASMR remained stable in Castilla-León and La Rioja (<75 years), Cantabria, Castilla-La Mancha and Valencia (≥75 years) and the 2 Castilian regions (all ages). For women, ASMR also decreased in Valencia (<75 and ≥75), Castilla-León (≥75), Galicia (≥75 and all ages) and Navarre (<75 and all ages). CONCLUSION: Our results reveal significant variations in trends by AC, sex and age group, emphasizing the need for continued follow-up and targeted interventions to further reduce bladder cancer mortality rates in Spain.

Thrombectomy with embed aspiration in acute ischaemic stroke.

BACKGROUND: In addition to stent retrievers, direct aspiration has become a reasonable thrombectomy strategy. OBJECTIVES: We carried out the thrombectomy by guiding the aspiration catheter fully over the clot and performing immediate manual aspiration; we call this procedure "embed aspiration". METHODS: In this prospective, non-randomised, single-centre study, we included all patients treated at a high volume-of-care stroke centre between 2017 and 2018 for the TRIANA (Thrombectomy in Andalusia using Aspiration) registry. Thrombectomy was carried out by embed aspiration. Patients were classified according to the success (eTICI 2b67-2c-3) or failure (eTICI 0-1-2a-2b50) of the procedure. Baseline clinical data and outcomes were compared, and multivariate analysis was performed. RESULTS: The embed aspiration technique was used in 370 patients. Treatment was successful in 90.3% of patients. Mean puncture-to-recanalisation time was 25 minutes. The overall rate of good outcomes (mRS 0-2) at 3 months was 64%. CONCLUSIONS: This study supports real-life evidence that standardised embed aspiration may be an alternative to stent retrievers for thrombectomy.

[Emergency transcranial doppler ultrasound: predictive value for the development of symptomatic vasospasm in spontaneous subarachnoid hemorrhage in patients in good neurological condition]. / Ultrasonografía doppler transcraneal urgente: utilidad predictiva del vasoespasmo sintomático en la hemorragia subaracnoidea espontánea en pacientes con buena situación neurológica.

PURPOSE: To examine the predictive value of an early transcranial Doppler ultrasound (TCD) study performed in the emergency department in patients with spontaneous subarachoniod hemorrhage (SAH) in good neurological condition, in order to know which patients are at high risk of developing delayed cerebral ischemia (DCI). DESIGN: A descriptive observational study was carried out involving a period of 3 years. SETTING: Critical Care and Emergency Department. PATIENTS: The study consecutively included patients with SAH of grade I-III on the Hunt and Hess scale. VARIABLES OF INTEREST: DCI (decrease of 2 points in GCS or focal deficit), Mean Velocity (MV) of middle cerebral arteries (MCA), Lindegaard Index (IL). Sonographic vasospasm pattern (SVP) was considered if MCA-MV>120cm/sc and IL>3. RESULTS: The mean age of the 122 patients was 54.1±13.7 years; 57.3% were women. SVP was detected in 24 patients (19.7%), although high velocities patterns (HVP) were present in 38 patients (31.1%). DCI developed in 21 patients (MV183+/-49cm/sc), all with previous SVP. In this group MV increased 22+/-5cm/sc/day during the first 3 days. The group without HVP (84 patients/MV of 67+/-16.6cm/sc), compared with DCI group, showed differences in highest MV (p<0.001), and also ΔMV/day (8.30+/-4,5cm/sc Vs 22+/-5cm/sc) during the first 3 days (p=0.009). In our series, ROC analysis selected the best cut-off value for ΔMV/day as 21cm/sc (p<0.001). CONCLUSION: During the first 3 days, an increase of 21cm/s/24h in MCA-MV was associated with the development of symptomatic vasospasm. TCD is a useful tool for the early detection of patients at risk of DCI after SAH.

Has stroke mortality stopped declining in Spain?

OBJECTIVES: To analyse the changes in stroke mortality trends in Spain by autonomous community and by sex during the period 1980-2016, using joinpoint regression models. METHODS: Mortality data were obtained from the Spanish National Statistics Institute. Crude and standardised rates were calculated for each Spanish autonomous community, and for each sex. Joinpoint analysis was used to identify the best-fitting points showing a statistically significant change in the trend. RESULTS: Joinpoint analysis enabled us to differentiate between communities in which mortality rates showed a continuous decline throughout the study period in both sexes (Asturias, Cantabria, Castile and Leon, Ceuta, and Melilla) or in men only (Extremadura). In men, in all those communities in which changes in the trend were observed (all but Aragon, the Balearic Islands, and Murcia, where rates remained stable), we observed an initial period of decline (ranging from -3.4% in Catalonia and Extremadura, to -6.0% in Madrid) and a final period where the trends diverged: mortality rates continued to fall in Andalusia, Aragon, the Balearic Islands, and Madrid, but began to stabilise in Castile-La Mancha and Murcia and to increase in the Canary Islands. In women, in those communities where changes were observed (all but Aragon, Murcia, and the Basque Country, where rates remained stable), we observed an initial period of decline (ranging from -3.1% in Catalonia to -6.4% in Navarre) and a final period where divergent trends were observed: rates continued to decline in Andalusia, Aragon, Catalonia, Galicia, Madrid, and the Basque Country, but began to stabilise in Extremadura and Murcia and to increase in the Canary Islands. CONCLUSIONS: Current data show that stroke mortality rates have decreased (in women in Andalusia), stabilised (in both sexes in Murcia, in men in Castile-La Mancha, and in women in Extremadura), and have even reversed (in both sexes in the Canary Islands). Further study is needed to identify the causes of these trends.

Study of colorectal mortality in the Andalusian population.

OBJECTIVES: to provide up-to-date information and to analyze recent changes in colorectal cancer mortality trends in Andalusia during the period of 1980-2008 using joinpoint regression models. PATIENTS AND METHODS: age- and sex-specific colorectal cancer deaths were taken from the official vital statistics published by the Instituto de Estadística de Andalucía for the years 1980 to 2008. We computed age-specific rates for each 5-year age group and calendar year and age-standardized mortality rates per 100,000 men and women. A joinpoint regression analysis was used for trend analysis of standardized rates. Joinpoint regression analysis was used to identify the years when a significant change in the linear slope of the temporal trend occurred. The best fitting points (the "join-points") are chosen where the rate significantly changes. RESULTS: mortality from colorectal cancer in Andalusia during the period studied has increased, from 277 deaths in 1980 to 1,227 in 2008 in men, and from 333 to 805 deaths in women. Adjusted overall colorectal cancer mortality rates increased from 7.7 to 17.0 deaths per 100,000 person-years in men and from 6.6 to 9.0 per 100,000 person-years in women Changes in mortality did not evolve similarly for men and women. Age-specific CRC mortality rates are lower in women than in men, which imply that women reach comparable levels of colorectal cancer mortality at higher ages than men. CONCLUSIONS: sex differences for colorectal cancer mortality have been widening in the last decade in Andalusia. In spite of the decreasing trends in age-adjusted mortality rates in women, incidence rates and the absolute numbers of deaths are still increasing, largely because of the aging of the population. Consequently, colorectal cancer still has a large impact on health care services, and this impact will continue to increase for many more years.

Recent trends in prostate cancer in Spain. / Tendencias recientes en cáncer de próstata en España.

OBJECTIVE: To assess recent trends in prostate cancer incidence, survival and mortality in Spain using updated data. SUBJECTS AND METHOD: Prostate cancer mortality data have been obtained from the National Institute of Statistics (INE). Incidence cases have been obtained from the databases Cancer Incidence in Five Continents (CI5) and European Cancer Information System. Joinpoint regression models were used for trend analysis. The results show the duration (years) of each trend, as well as the Annual Percent Change (APC) for each of them. The direction and magnitude of recent trends (last 5 years available) were evaluated using the percentages of Average Annual Percent Change (AAPC). RESULTS: Incidence rates increased significantly from 16.4 in 1980 to 61.3 in 2014. The joinpoint analysis shows three periods: two initial periods of significant rise (1980-1990; 3.5% and 1990-2004; 8.4%) followed by a final one in which rates stabilize (2004-2014; -0.5%, non-significant). Mortality rates drop from 12.9 in 1980 to 7.9 in 2018, with an AAPC of -1.2% (p<0.05). However, the joinpoint analysis identified three time periods: an initial period of statistically significant rise (1980-1998; APC: 0.6%, p<0.05) and two periods of decreasing rates (1992-2008; APC: -3.3%, p<0.05 and 2008-2018; APC: -2.4%, p<0.05). CONCLUSION: Recent trends (last 5 years) show that mortality rates have decreased and incidence rates have stabilized or even decreased in some age groups.

Multivariate explanatory model for sporadic carcinoma of the colon in Dukes' stages I and IIa.

OBJECTIVE: We obtained before an explanatory model with six dependant variables: age of the patient, total cholesterol (TC), HDL cholesterol (HDL-C), VLDL cholesterol (VLDL-C), alkaline phosphatase (AP) and the CA 19.9 tumour marker. Our objective in this study was to validate the model by means of the acquisition of new records for an additional analysis. DESIGN: Non-paired case control study. SETTING: Urban and rural hospitals and primary health facilities in Western Andalusia and Extremadura (Spain). PATIENTS: At both the primary care facilities and hospital level, controls were gathered in a prospective manner (n= 275). Cases were prospective and retrospective manner collected on (n=126). MAIN OUTCOME MEASURES: Descriptive statistics, logistic regression and bootstrap analysis. RESULTS: The AGE (odds ratio 1.02; 95% CI 1.003-1.037) (p= 0.01), the TC (odds ratio 0.986; 95% C.I. 0.980-0.992) (p< 0.001) and the CA 19.9 (odds ratio 1.023; 95% C.I. 1.012- 1.034) (p<0.001) were the variables that showed significant values at logistic regression analysis and bootstrap. Berkson's bias was statistically assessed. CONCLUSIONS: The model, validated by means of logistic regression and bootstrap analysis, contains the variables AGE, TC, and CA 19.9 (three of the original six) and has a level 4 over 5 according to the criteria of Justice et al. (multiple independent validations) [Ann. Intern. Med.1999; 130: 515].

[Proteinuria in urinary infection and acute pyelonephritis in paediatric patients: can it replace scintigraphic studies in diagnostic localisation?]. / Estudio de proteinuria en infección urinaria y pielonefritis aguda en Pediatría: ¿puede sustituir en el diagnóstico de localización al estudio gammagráfico?

UNLABELLED: ANTECEDENTS AND OBJECTIVES: The location of the urinary tract infection in children has serious implications both in therapy and prognosis. Affectation in gammagraphic studies is considered the "gold standard" for the diagnosis of acute pyelonephritis. Several studies with biomarkers have been made with controverted results. The objective of this study is to set the utility of beta2-microglobuline, alfa1-microglobuline, Cistatine C, IgG and albumin in the location of the infection, through the analysis of the relation among their urinary excretion, clinical and laboratory parameters and the renal scintigraphy findings. PATIENTS AND METHODS: Prospective observational study made in 40 patients, aged from 1 month to 11 years, after their Hospital admission with suspicion for acute pyelonephritis. Exclusion criteria were: decrease in the glomerular filtration rate, malnutrition, massive albuminuria and history or findings of nephrourologic disease. Clinical and laboratory variables were analyzed, and renal ultrasonography and scintigraphy were performed within the first seven days after admission. Once the fever dropped, the urinary creatinine-protein ratio was analyzed. After the acute process, a renal scintigraphy was performed in order to detect renal scars. The non-parametric Mann-Whitney U test has been used as the statistical hypothesis test, and Chi-square and Fisher s exact tests have been used to compare the qualitative variables. RESULTS: The glomerular filtration rate, as well as the ultrasonography scan, was normal in all patients. 45% of the children (24/80 kidneys) had scintigraphic alterations that were compatible with acute pyelonephritis, and there were not differences in proteinuria between these and those with normal scintigraphy. To greater age greater probability of scintigraphic affectation. The sensitivity and specificity of leukocytes and CRP to predict pyelonephritis were 77-65% and 94-52%, r = 0.70 (CI 95% 0.54-0.87) y 0.75 (CI 95% 0.60-0.90) respectively. An apparent relation between the maximum temperature or duration of the symptoms and the renal affectation does not exist. In all the children, the normality of urinary markers of renal function was confirmed once the acute phase had passed, even in those 3 patients with renal scars (7.5%). CONCLUSIONS: Renal scintigraphy is still being the reference pattern for the diagnosis of acute pyelonephritis in Pediatrics. The combined use of different urinary markers of renal function does not increase its sensitivity. It is necessary to do research in order to confirm the utility of new biomarkers.

Malignant colonic adenomas. Therapeutic criteria. Long-term results of therapy in a series of 42 patients in our healthcare area.

OBJECTIVE: a) to evaluate the appropriateness of histological criteria as proposed by Morson as indicators for surgery; and b) to compare the adequacy of Morson s criteria with Haggitt s levels as indicators for surgery in the case of malignant sessile lesions. MATERIAL AND METHODS: we carried out a prospective, protocolized study of 42 patients with polyps with invasive carcinoma (IC) who underwent colonoscopic polypectomy from 1979 through 2008. We applied the histological criteria proposed by Morson to all the patients included in the series. RESULTS: we treated 24 polyps with IC and favorable histological criteria (FC) and 18 polyps showing unfavorable histological criteria (UC). All polyps with FC were treated by means of colonoscopic polypectomy. None of the patients showed signs of disease after a mean follow-up period o f 9.67 yrs. Patients with polyps with UC were recommended to undergo surgery. The presence of unfavorable histological criteria in the polypectomy sample was clearly associated with an unfavorable patient outcome and showed a 100% sensitivity level, a negative prognostic value (NPV) of 100%, and a false negative (FN) percentage of 0% for the prognosis of the disease. We found 12 sessile polyps (Haggitt s level 4). Colonoscopic polypectomy was the treatment employed in 9 out of 12 cases. All patients are free from disease (mean follow-up 7.3 yrs). If Haggitt s level criteria had been applied, all 12 patients would have undergone surgery. This means 58% more patients than following Morson s criteria. CONCLUSIONS: Morson s criteria are considered an adequate diagnostic tool for the indication of surgery in patients with malignant adenomas. Haggitt s invasion levels do not accurately discriminate the necessity for surgery in case of malignant sessile lesions.

Analysis of cerebrovascular disease mortality trends in Andalusia (1980-2014). / Análisis de las tendencias en la mortalidad por enfermedades cerebrovasculares en Andalucía (1980-2014).

INTRODUCTION: In recent decades, mortality rates for cerebrovascular diseases (CVD) have decreased significantly in many countries. This study analyses recent tendencies in CVD mortality rates in Andalusia (1980-2014) to identify any changes in previously observed sex and age trends. PATIENTS AND METHODS: CVD mortality and population data were obtained from Spain's National Statistics Institute database. We calculated age-specific and age-standardised mortality rates using the direct method (European standard population). Joinpoint regression analysis was used to estimate the annual percentage change in rates and identify significant changes in mortality trends. We also estimated rate ratios between Andalusia and Spain. RESULTS: Standardised rates for both males and females showed 3 periods in joinpoint regression analysis: an initial period of significant decline (1980-1997), a period of rate stabilisation (1997-2003), and another period of significant decline (2003-2014). CONCLUSIONS: Between 1997 and 2003, age-standardised rates stabilised in Andalusia but continued to decrease in Spain as a whole. This increased in the gap between CVD mortality rates in Andalusia and Spain for both sexes and most age groups.

Has stroke mortality stopped declining in Spain? / ¿Ha dejado de disminuir la mortalidad por enfermedades cerebrovasculares en España?

OBJECTIVES: To analyse the changes in stroke mortality trends in Spain by autonomous community and by sex during the period 1980-2016, using joinpoint regression models. METHODS: Mortality data were obtained from the Spanish National Statistics Institute. Crude and standardised rates were calculated for each Spanish autonomous community, and for each sex. Joinpoint analysis was used to identify the best-fitting points showing a statistically significant change in the trend. RESULTS: Joinpoint analysis enabled us to differentiate between communities in which mortality rates showed a continuous decline throughout the study period in both sexes (Asturias, Cantabria, Castile and Leon, Ceuta, and Melilla) or in men only (Extremadura). In men, in all those communities in which changes in the trend were observed (all but Aragon, the Balearic Islands, and Murcia, where rates remained stable), we observed an initial period of decline (ranging from -3.4% in Catalonia and Extremadura, to -6.0% in Madrid) and a final period where the trends diverged: mortality rates continued to fall in Andalusia, Aragon, the Balearic Islands, and Madrid, but began to stabilise in Castile-La Mancha and Murcia and to increase in the Canary Islands. In women, in those communities where changes were observed (all but Aragon, Murcia, and the Basque Country, where rates remained stable), we observed an initial period of decline (ranging from -3.1% in Catalonia to -6.4% in Navarre) and a final period where divergent trends were observed: rates continued to decline in Andalusia, Aragon, Catalonia, Galicia, Madrid, and the Basque Country, but began to stabilise in Extremadura and Murcia and to increase in the Canary Islands. CONCLUSIONS: Current data show that stroke mortality rates have decreased (in women in Andalusia), stabilised (in both sexes in Murcia, in men in Castile-La Mancha, and in women in Extremadura), and have even reversed (in both sexes in the Canary Islands). Further study is needed to identify the causes of these trends.

Lung cancer mortality trends by geographical area in Spanish women, 1980-2005.

OBJECTIVE: To provide up-to-date information and analyse recent changes in lung cancer mortality trends among women. DESIGN: The present study analysed subjects by geographical area in Spain during the period 1980-2005 using joinpoint regression models. Age-standardised mortality rates (ASR) for lung cancer were computed from death certificate data obtained from the official authorities in Spain. Joinpoint regression analysis was used to identify the years when significant changes in the linear slope of the temporal trend occurred. RESULTS: The overall ASR changed during the period studied from 5.7 per 100,000 women in 1980 to 8.2/100,000 in 2005, with an average annual increase of 1.7%. Joinpoint regression analysis detected different trends in most Spanish communities. These changes occurred in the late 1980s or early 1990s. ASR among those women aged 35-64 years doubled during the period of study, from 5.6 in 1980 to 11.3 in 2005. CONCLUSIONS: Time trends in lung cancer mortality among women are increasing sharply, especially in the age group 35-64 years, indicating the start of an epidemic phenomenon of lung cancer in women.
