Análisis de la esperanza de vida libre de discapacidad a lo largo de la biografía: de la madurez a la vejez

Objetivo: determinar en qué etapas del curso de vida previo a los setenta años se acortan las expectativas de vida en salud. Método: análisis longitudinal retrospectivo. La población a estudio es una cohorte de 1286 individuos de entre 70 y 74 años de edad que viven en áreas metropolitanas no institucionalizados. La discapacidad se mide mediante el desarrollo de las actividades instrumentales de la vida diaria (AIVD) y las actividades básicas de la vida diaria (ABVD). Se calculan las esperanzas de vida libre de discapacidad y la probabilidades de supervivencia mediante Kaplan-Meier Resultados: La incidencia de discapacidad básica se incrementó a partir del tramo de 50 a 54 años acelerándose progresivamente hasta los 65-69 años donde la probabilidad de padecer discapacidad instrumental fue ligeramente superior en hombres que en mujeres (0,23 en hombres versus 0,19 en mujeres). La supervivencia sin discapacidad de las mujeres fue peor que la de los hombres tanto para cualquier tipo de discapacidad (LogRank = 5,80; p = 0,016) como para la discapacidad básica (LogRank = 4,315; p = 0,038). Conclusiones: se pone de manifiesto el importante peso que para la autonomía de la población masculina de estas edades tiene la falta de habilidad instrumental para cuestiones domésticas. Además, las mujeres ostentan un peor pronóstico de supervivencia sin discapacidad tanto para cualquier tipo de discapacidad como para la discapacidad básica. Para ambos sexos, desde los 40 hasta los 60 años de edad, hay un ligero descenso de la supervivencia sin discapacidad. A partir de esta edad, el descenso se acelera notablemente.

Global surveillance of cancer survival 1995-2009 : analysis of individual data for 25 676 887 patients from 279 population-based registries in 67 countries (CONCORD-2)

BACKGROUND: Worldwide data for cancer survival are scarce. We aimed to initiate worldwide surveillance of cancer survival by central analysis of population-based registry data, as a metric of the effectiveness of health systems, and to inform global policy on cancer control. METHODS: Individual tumour records were submitted by 279 population-based cancer registries in 67 countries for 25·7 million adults (age 15-99 years) and 75 000 children (age 0-14 years) diagnosed with cancer during 1995-2009 and followed up to Dec 31, 2009, or later. We looked at cancers of the stomach, colon, rectum, liver, lung, breast (women), cervix, ovary, and prostate in adults, and adult and childhood leukaemia. Standardised quality control procedures were applied; errors were corrected by the registry concerned. We estimated 5-year net survival, adjusted for background mortality in every country or region by age (single year), sex, and calendar year, and by race or ethnic origin in some countries. Estimates were age-standardised with the International Cancer Survival Standard weights. FINDINGS: 5-year survival from colon, rectal, and breast cancers has increased steadily in most developed countries. For patients diagnosed during 2005-09, survival for colon and rectal cancer reached 60% or more in 22 countries around the world; for breast cancer, 5-year survival rose to 85% or higher in 17 countries worldwide. Liver and lung cancer remain lethal in all nations: for both cancers, 5-year survival is below 20% everywhere in Europe, in the range 15-19% in North America, and as low as 7-9% in Mongolia and Thailand. Striking rises in 5-year survival from prostate cancer have occurred in many countries: survival rose by 10-20% between 1995-99 and 2005-09 in 22 countries in South America, Asia, and Europe, but survival still varies widely around the world, from less than 60% in Bulgaria and Thailand to 95% or more in Brazil, Puerto Rico, and the USA. For cervical cancer, national estimates of 5-year survival range from less than 50% to more than 70%; regional variations are much wider, and improvements between 1995-99 and 2005-09 have generally been slight. For women diagnosed with ovarian cancer in 2005-09, 5-year survival was 40% or higher only in Ecuador, the USA, and 17 countries in Asia and Europe. 5-year survival for stomach cancer in 2005-09 was high (54-58%) in Japan and South Korea, compared with less than 40% in other countries. By contrast, 5-year survival from adult leukaemia in Japan and South Korea (18-23%) is lower than in most other countries. 5-year survival from childhood acute lymphoblastic leukaemia is less than 60% in several countries, but as high as 90% in Canada and four European countries, which suggests major deficiencies in the management of a largely curable disease. INTERPRETATION: International comparison of survival trends reveals very wide differences that are likely to be attributable to differences in access to early diagnosis and optimum treatment. Continuous worldwide surveillance of cancer survival should become an indispensable source of information for cancer patients and researchers and a stimulus for politicians to improve health policy and health-care systems.

Tratamentos hidrotérmico e com radiação UV-C no controle pós-colheita da podridão olho-de-boi em uma linha comercial de seleção de maçãs

Avaliaram-se os efeitos da aspersão hidrotérmica e da radiação UV-C no controle pós-colheita da podridão olho-de-boi (POB) em maçãs 'Fuji', após um e oito meses de armazenamento, e 'Gala', após cinco meses de armazenamento, ambas sob condição de atmosfera controlada (AC). Esses frutos foram inoculados ou mantidos com infecção natural de Cryptosporiopsis perennans. As maçãs 'Fuji' foram submetidas aos seguintes tratamentos, aplicados em uma linha comercial de seleção: sem tratamento (testemunha); aspersão hidrotérmica (água a 50ºC por 12 segundos); radiação UV-C (0,0069 kJ m-2); e aspersão hidrotérmica + radiação UV-C. As maçãs 'Gala' também foram submetidas a estes tratamentos utilizados em 'Fuji', exceto ao tratamento com aspersão hidrotérmica + radiação UV-C. Após os tratamentos, as maçãs foram incubadas a 22ºC por 15 dias e avaliadas quanto à incidência da doença. Nas maçãs 'Fuji', os tratamentos de aspersão hidrotérmica e/ou radiação UV-C reduziram a incidência da POB nos frutos inoculados e com infecção natural, proporcionando controle superior a 56% e 54%, em relação à testemunha, respectivamente. Em maçãs 'Gala' inoculadas, os tratamentos com aspersão hidrotérmica e radiação UV-C também reduziram o número de unidades formadoras de colônias (UFC) nos frutos, com controle superior a 70%, e a incidência da POB, com controle superior a 69% em relação à testemunha. Em maçãs 'Gala', com infecção natural, estes tratamentos apresentaram controle da POB superior a 85% em relação à testemunha. Os resultados obtidos mostram que os tratamentos com aspersão hidrotérmica e/ou radiação UV-C reduzem a incidência da POB em maçãs 'Fuji' e 'Gala', em linha comercial de seleção. Todavia, o uso da radiação UV-C, em ambas as cultivares, foi o tratamento que apresentou maior benefício e retorno econômico.

Effect of feed fat by-products with trans fatty acids and heated oil on cholesterol and oxycholesterols in chicken

Chicken is the most widely consumed meat all over the world due to chickens being easy to rear, their fast growth rate and the meat having good nutritional characteristics. The main objective of this paper was to study the effects of dietary fatty by-products in low, medium and high levels of oxidized lipids and trans fatty acids (TFAs) on the contents of cholesterol and oxycholesterols in meat, liver, and plasma of chickens. A palm fatty acid distillate, before and after hydrogenation, and a sunflower-olive oil blend (70/30, v/v) before and after use in a commercial frying process were used in feeding trials after adding 6% of the fats to the feeds. Highly oxidized lipid and TFA feeds significantly increased the contents of cholesterol and oxycholesterols in all tissues of chicken (0.01 < p <= 0.05). The contents of oxycholesterols in chicken meat, liver and plasma obtained from TFA feeding trials varied between 17 and 48 μg/100 g in meat, 19-42 μg/100 g in liver and 105-126 μg/dL in plasma. In contrast, in the oxidized lipid feeding trials, oxycholesterols varied between 13 and 75 μg/100 g in meat, 30-58 μg/100 g in liver and 66-209 μg/dL in plasma. Meat from chickens fed with feeds containing high levels of TFAs or oxidized lipids may contribute to higher ingestion of cholesterol and oxycholesterols by humans.

Subclinical thyroid dysfunction and fracture risk: a meta-analysis.

IMPORTANCE: Associations between subclinical thyroid dysfunction and fractures are unclear and clinical trials are lacking. OBJECTIVE: To assess the association of subclinical thyroid dysfunction with hip, nonspine, spine, or any fractures. DATA SOURCES AND STUDY SELECTION: The databases of MEDLINE and EMBASE (inception to March 26, 2015) were searched without language restrictions for prospective cohort studies with thyroid function data and subsequent fractures. DATA EXTRACTION: Individual participant data were obtained from 13 prospective cohorts in the United States, Europe, Australia, and Japan. Levels of thyroid function were defined as euthyroidism (thyroid-stimulating hormone [TSH], 0.45-4.49 mIU/L), subclinical hyperthyroidism (TSH <0.45 mIU/L), and subclinical hypothyroidism (TSH ≥4.50-19.99 mIU/L) with normal thyroxine concentrations. MAIN OUTCOME AND MEASURES: The primary outcome was hip fracture. Any fractures, nonspine fractures, and clinical spine fractures were secondary outcomes. RESULTS: Among 70,298 participants, 4092 (5.8%) had subclinical hypothyroidism and 2219 (3.2%) had subclinical hyperthyroidism. During 762,401 person-years of follow-up, hip fracture occurred in 2975 participants (4.6%; 12 studies), any fracture in 2528 participants (9.0%; 8 studies), nonspine fracture in 2018 participants (8.4%; 8 studies), and spine fracture in 296 participants (1.3%; 6 studies). In age- and sex-adjusted analyses, the hazard ratio (HR) for subclinical hyperthyroidism vs euthyroidism was 1.36 for hip fracture (95% CI, 1.13-1.64; 146 events in 2082 participants vs 2534 in 56,471); for any fracture, HR was 1.28 (95% CI, 1.06-1.53; 121 events in 888 participants vs 2203 in 25,901); for nonspine fracture, HR was 1.16 (95% CI, 0.95-1.41; 107 events in 946 participants vs 1745 in 21,722); and for spine fracture, HR was 1.51 (95% CI, 0.93-2.45; 17 events in 732 participants vs 255 in 20,328). Lower TSH was associated with higher fracture rates: for TSH of less than 0.10 mIU/L, HR was 1.61 for hip fracture (95% CI, 1.21-2.15; 47 events in 510 participants); for any fracture, HR was 1.98 (95% CI, 1.41-2.78; 44 events in 212 participants); for nonspine fracture, HR was 1.61 (95% CI, 0.96-2.71; 32 events in 185 participants); and for spine fracture, HR was 3.57 (95% CI, 1.88-6.78; 8 events in 162 participants). Risks were similar after adjustment for other fracture risk factors. Endogenous subclinical hyperthyroidism (excluding thyroid medication users) was associated with HRs of 1.52 (95% CI, 1.19-1.93) for hip fracture, 1.42 (95% CI, 1.16-1.74) for any fracture, and 1.74 (95% CI, 1.01-2.99) for spine fracture. No association was found between subclinical hypothyroidism and fracture risk. CONCLUSIONS AND RELEVANCE: Subclinical hyperthyroidism was associated with an increased risk of hip and other fractures, particularly among those with TSH levels of less than 0.10 mIU/L and those with endogenous subclinical hyperthyroidism. Further study is needed to determine whether treating subclinical hyperthyroidism can prevent fractures.

Assessment of subjective and hemodynamic tolerance of different high- and low-flux dialysis membranes in patients undergoing chronic intermittent hemodialysis: a randomized controlled trial.

Clinical experience and experimental data suggest that intradialytic hemodynamic profiles could be influenced by the characteristics of the dialysis membranes. Even within the worldwide used polysulfone family, intolerance to specific membranes was occasionally evoked. The aim of this study was to compare hemodynamically some of the commonly used polysulfone dialyzers in Switzerland. We performed an open-label, randomized, cross-over trial, including 25 hemodialysis patients. Four polysulfone dialyzers, A (Revaclear high-flux, Gambro, Stockholm, Sweden), B (Helixone high-flux, Fresenius), C (Xevonta high-flux, BBraun, Melsungen, Germany), and D (Helixone low-flux, Fresenius, Bad Homburg vor der Höhe, Germany), were compared. The hemodynamic profile was assessed and patients were asked to provide tolerance feedback. The mean score (±SD) subjectively assigned to dialysis quality on a 1-10 scale was A 8.4 ± 1.3, B 8.6 ± 1.3, C 8.5 ± 1.6, D 8.5 ± 1.5. Kt/V was A 1.58 ± 0.30, B 1.67 ± 0.33, C 1.62 ± 0.32, D 1.45 ± 0.31. The low- compared with the high-flux membranes, correlated to higher systolic (128.1 ± 13.1 vs. 125.6 ± 12.1 mmHg, P < 0.01) and diastolic (76.8 ± 8.7 vs. 75.3 ± 9.0 mmHg; P < 0.05) pressures, higher peripheral resistance (1.44 ± 0.19 vs. 1.40 ± 0.18 s × mmHg/mL; P < 0.05) and lower cardiac output (3.76 ± 0.62 vs. 3.82 ± 0.59 L/min; P < 0.05). Hypotension events (decrease in systolic blood pressure by >20 mmHg) were 70 with A, 87 with B, 73 with C, and 75 with D (P < 0.01 B vs. A, 0.05 B vs. C and 0.07 B vs. D). The low-flux membrane correlated to higher blood pressure levels compared with the high-flux ones. The Helixone high-flux membrane ensured the best efficiency. Unfortunately, the very same dialyzer correlated to a higher incidence of hypotensive episodes.

Central odontogenic fibroma: retrospective study of 8 clinical cases

Introduction and Objectives: The central odontogenic fibroma (COF) is a benign odontogenic tumour derived from the dental mesenchymal tissues. It is a rare tumour and only 70 cases of it have been published. Bearing in mind the rareness of the tumour, 8 new cases of central odontogenic fibroma have been found by analyzing the clinical, radiological and histopathological characteristics of COF. Patients and Method: A retrospective study was carried out on 3011 biopsies in the Service of Oral and Maxillofacial Surgery of the Dental Clinic of Barcelona University between January 1995 and March 2008. 85 odontogenic tumours were diagnosed of which 8 were central odontogenic fibroma. The radiological study was based on orthopantomographs, periapical and occlusal radiographies and computerised tomographics. The variables collected were: sex, age, clinical characteristics of the lesion, treatment received and possible reappearances of the tumour. Results: The central odontogenic fibroma represents 9.4% of all odontogenic tumours. Of the 8 cases, 5 were diagnosed in men and 3 in women. The average age was 19.9 years with an age range of 11 to 38 years. The most common location of the tumour was in the mandible. All cases were associated with unerupted teeth. Of the 8 tumours, 3 provoked rhizolysis of the adjacent teeth and 4 cases caused cortical bone expansion. 50% of the patients complained of pain associated to the lesion. No case of recurrence was recorded up to 2 years after the treatment. Conclusions: Central odontogenic fibromas usually evolve asymptomatically although they can manifest very aggressively provoking dental displacement and rhizolysis. Radiologically, COF manifest as a uni or multilocular radiotransparent image although they can be indistinguishable from other radiotransparent lesions making diagnosis more difficult. COF treatment involves conservative surgery as well as follow-up patient checks.

Modificaciones en el consumo de tabaco durante la gestación y el posparto

Objetivo: Averiguar el consumo de tabaco y las modificaciones del hábito durante la gestación, y observar las recaídas después del parto. Personas y método: Estudio descriptivo transversal, realizado en el PASSIR «Casagemas», Badalona, desde febrero de 2006 a septiembre de 2007. Se incluyó a 115 gestantes que acudieron a la consulta de control prenatal en el tercer trimestre de gestación, y se excluyeron las que no fumaban al inicio de la gestación. Se recogieron variables sociodemográficas y las relacionadas con el hábito tabáquico a través de un cuestionario en la gestación y otro en el posparto. Resultados: Dejaron de fumar el 26% (30) de las gestantes, y las que continuaron fumando redujeron el consumo de una media de 19,2 (DE= 6,7) a 7,2 (DE= 6) cigarrillos/día. Se observaron diferencias en el abandono del tabaco en aquellas que fumaban un menor número de cigarrillos (p <0,001), en las que iniciaron el tabaquismo más tarde y en las de mayor edad (p= 0,013). Al año del parto, seguían fumando el 73% (70) de las mujeres, y habían recaído en el hábito el 39,2% (11) de las que lo habían abandonado en la gestación. Las mujeres que no fumaban lactaron a sus hijos un 76,9% (20), mientras que las que fumaban lo hicieron un 57,1% (40). La duración media de la lactancia fue inferior en las mujeres que fumaron en el posparto (2,81 meses [DE= 3,4]) en relación con las que no lo hicieron (4,96 meses [DE= 4,1]; p= 0,01). Conclusiones: La tasa de abandono del tabaco durante el embarazo es aún muy baja, y el índice de recaída del hábito tabáquico en el posparto, elevada.
