OBJECTIVE: To evaluate deaths from AIDS-defining malignancies (ADM) and non-AIDS-defining malignancies (nADM) in the D:A:D Study and to investigate the relationship between these deaths and immunodeficiency. DESIGN: Observational cohort study. METHODS: Patients (23 437) were followed prospectively for 104 921 person-years. We used Poisson regression models to identify factors independently associated with deaths from ADM and nADM. Analyses of factors associated with mortality due to nADM were repeated after excluding nADM known to be associated with a specific risk factor. RESULTS: Three hundred five patients died due to a malignancy, 298 prior to the cutoff for this analysis (ADM: n = 110; nADM: n = 188). The mortality rate due to ADM decreased from 20.1/1000 person-years of follow-up [95% confidence interval (CI) 14.4, 25.9] when the most recent CD4 cell count was <50 cells/microl to 0.1 (0.03, 0.3)/1000 person-years of follow-up when the CD4 cell count was more than 500 cells/microl; the mortality rate from nADM decreased from 6.0 (95% CI 3.3, 10.1) to 0.6 (0.4, 0.8) per 1000 person-years of follow-up between these two CD4 cell count strata. In multivariable regression analyses, a two-fold higher latest CD4 cell count was associated with a halving of the risk of ADM mortality. Other predictors of an increased risk of ADM mortality were homosexual risk group, older age, a previous (non-malignancy) AIDS diagnosis and earlier calendar years. Predictors of an increased risk of nADM mortality included lower CD4 cell count, older age, current/ex-smoking status, longer cumulative exposure to combination antiretroviral therapy, active hepatitis B infection and earlier calendar year. CONCLUSION: The severity of immunosuppression is predictive of death from both ADM and nADM in HIV-infected populations.

OBJECTIVES: To delineate the various factors contributing to failure or delay in decannulation after partial cricotracheal resection (PCTR) in children. STUDY DESIGN: Case series. SETTING: Academic tertiary medical center. SUBJECTS AND METHODS: A retrospective case review of 100 children who underwent PCTR between 1978 and 2008 for severe subglottic stenosis using an ongoing database. RESULTS: Ninety of 100 (90%) patients were decannulated. Six patients needed secondary tracheostomy. The results of the preoperative evaluation showed grade II stenosis in four patients, grade III in 64 patients, and grade IV in 32 patients. The overall decannulation rate was 100 percent in grade II, 95 percent in grade III, and 78 percent in grade IV stenosis. Fourteen (14%) patients required revision open surgery. The most common cause of revision surgery was posterior glottic stenosis. Partial anastomotic dehiscence was seen in four patients. Delayed decannulation (>1 year) occurred in nine patients. Overall mortality rate in the whole series was 6 percent. No deaths were directly related to the surgery. No iatrogenic recurrent laryngeal nerve injury was present in the entire series. CONCLUSION: Comorbidities and associated syndromes should be addressed before PCTR is planned to improve the final postoperative outcome in terms of decannulation. Perioperative morbidity due to anastomotic dehiscence, to a certain extent, can be avoided by intraoperative judgment in the selection of double-stage surgery when more than five tracheal rings need to be resected. Subglottic stenosis with glottic involvement continues to pose a difficult challenge to pediatric otolaryngologists, often necessitating revision procedures.

INTRODUCTION: to assess the outcome of endovascular aortic aneurysm repair (EVAR) using intravascular ultrasound (IVUS) without angiography. MATERIALS/METHODS: eighty consecutive patients (median age 69 years (range 25-90): male 72 (90%), female 8 (10%)) underwent endovascular aneurysm repair (AAA 68 (85%), TAA 12 (15%)) using either angiography in 31/80 patients (39%) or IVUS in 49/80 patients (61%) in accordance to the surgeons preference. RESULTS: hospital mortality was 2/80 (3%), 1/68 for AAA (2%), 1/12 for TAA (8%), 2/31 for angiography (7%), and 0/49 for IVUS (0.0%: NS). Median quantity of contrast medium was 190 ml (range: 20-350) for angiography versus 0 ml for IVUS (p<0.01). Median X-ray exposure time 24 min (range 9-65 min) versus 8 min (range 0-60 min) for IVUS (p<0.05). No coverage of renal or suprarenal artery orifices occurred in either group. Conversion to open surgery was necessary in 4/80 patients (5%), 1/31 for angiography (3%) and 3/49 patients for IVUS (6%: NS). Early endoleaks were observed in 13/80 patients (16%): 8/31 patients for angiography (26%) versus 5/49 for IVUS (10%: p<0.05): 5/13 endoleaks resolved spontaneously (39%) whereas 8/13 (61%) required additional procedures. CONCLUSIONS: IVUS is a reliable tool for EVAR. In most cases, perprocedural angiography is not necessary.

BACKGROUND: Chronic kidney disease (CKD) is associated to a higher stroke risk. Anemia is a common consequence of CKD, and is also a possible risk factor for cerebrovascular diseases. The purpose of this study was to examine if anemia and CKD are independent risk factors for mortality after stroke. METHODS: This historic cohort study was based on a stroke registry and included patients treated for a first clinical stroke in the stroke unit of one academic hospital over a three-year period. Mortality predictors comprised demographic characteristics, CKD, glomerular filtration rate (GFR), anemia and other stroke risk factors. GFR was estimated by means of the simplified Modification of Diet in Renal Disease formula. Renal function was assessed according to the Kidney Disease Outcomes Quality Initiative (K/DOQI)-CKD classification in five groups. A value of hemoglobin < 120 g/L in women and < 130 g/L in men on admission defined anemia. Kaplan-Meier survival curves and Cox models were used to describe and analyze one-year survival. RESULTS: Among 890 adult stroke patients, the mean (Standard Deviation) calculated GFR was 64.3 (17.8) ml/min/1.73 m2 and 17% had anemia. Eighty-two (10%) patients died during the first year after discharge. Among those, 50 (61%) had K/DOQI CKD stages 3 to 5 and 32 (39%) stages 1 or 2 (p < 0.001). Anemia was associated with an increased risk of death one year after discharge (p < 0.001). After adjustment for other factors, a higher hemoglobin level was independently associated with decreased mortality one year after discharge [hazard ratio (95% CI) 0.98 (0.97-1.00)]. CONCLUSIONS: Both CKD and anemia are frequent among stroke patients and are potential risk factors for decreased one-year survival. The inclusion of patients with a first-ever clinical stroke only and the determination of anemia based on one single measure, on admission, constitute limitations to the external validity. We should investigate if an early detection and management of both CKD and anemia could improve survival in stroke patients.

Reliable estimates of the post-release mortality probability of marine turtles after incidental by-catch are essential for assessing the impact of longline fishing on these species.Large numbers of loggerhead turtles Caretta caretta from rookeries in the northwestern Atlantic Ocean have been by-caught annually in the southwestern Mediterranean Sea since the 1980s, but nothing is known about their post-release mortality probability under natural conditions. Pop-up archival transmitting tags were attached to 26 loggerhead turtles following incidental capture by Spanish longliners. Hooks were not removed, and 40 cm of line was left in place. The post-release mortality probability during the 90 d following release ranged from 0.308 to 0.365, and was independent of hook location. When the post-release mortality probability was combined with previously reported estimates of the mortality probability before hauling, the aggregated by-catch mortality probability ranged from 0.321 to 0.378. Assuming a total annual by-catch of 10656 loggerhead turtles by the Spanish longline fleet operating in the southwestern Mediterranean, by-catch results in 3421 to 4028 turtle deaths annually. This range is equivalent to 8.5−10.1% of the approximately 40000 turtles inhabiting the fishing grounds used by Spanish longliners, most of them from rookeries in the northwestern Atlantic. As a consequence, the accumulated mortality during the oceanic stage is expected to be larger for those loggerhead turtles of Atlantic origin that spend several years in the Mediterranean Sea than for turtles of the same cohort that remain in the Atlantic. For this reason, the Mediterranean can be considered a dead end for loggerhead turtle populations nesting in the Atlantic, although the actual demographic relevance of by-catch mortality of loggerhead turtles in the Mediterranean remains unknown.

Evidence on trends in prevalence of disease and disability can clarify whether countries are experiencing a compression or expansion of morbidity. An expansion of morbidity as indicated by disease have appeared in Europe and other developed regions. It is likely that better treatment, preventive measures and increases in education levels have contributed to the declines in mortality and increments in life expectancy. This paper examines whether there has been an expansion of morbidity in Catalonia (Spain). It uses trends in mortality and morbidity from major causes of death and links of these with survival to provide estimates of life expectancy with and without diseases and functioning loss. We use a repeated cross-sectional health survey carried out in 1994 and 2011 for measures of morbidity; mortality information comes from the Spanish National Statistics Institute. Our findings show that at age 65 the percentage of life with disease increased from 52% to 70% for men, and from 56% to 72% for women; the expectation of life unable to function increased from 24% to 30% for men and 40% to 47% for women between 1994 and 2011. These changes were attributable to increases in the prevalences of diseases and moderate functional limitation. Overall, we find an expansion of morbidity along the period. Increasing survival among people with diseases can lead to a higher prevalence of diseases in the older population. Higher prevalence of health problems can lead to greater pressure on the health care system and a growing burden of disease for individuals.

Contexte L'hyperthyroïdie infra-clinique est une perturbation de la fonction thyroïdienne, définie par une thyrotropine (TSH) basse et des taux normaux de thyroxine libre (T4L) et triiodothyronine (T3). Cette dysfonction affecte de 1% à 5% des adultes de plus de 65 ans, surtout les femmes, et pourrait être associée avec les maladies cardiovasculaires, la fibrillation auriculaire et l'insuffisance cardiaque. Toutefois, les conclusions des différentes études de cohortes sont contradictoires, avec des limites méthodologiques empêchant leur comparaison de manière formelle. L'objet du travail de thèse était d'estimer le risque de mortalité de toute cause, le risque de mortalité de cause cardiovasculaire, le risque d'événements cardiovasculaires et le risque de fibrillation auriculaire associés à l'hyperthyroïdie infra-clinique dans toutes les grandes études de cohorte prospectives disponibles à ce jour. Méthode et Résultats Les données individuelles de 52'674 participants provenant de 10 études de cohorte prospectives des Etats-Unis, d'Europe, du Brésil et d'Australie ont été analysées pour évaluer les risques à long-terme de l'hyperthyroïdie infra-clinique. L'euthyroïdie était définie par une TSH entre 0.45 et 4.49 mUI/l et l'hyperthyroïdie infra-clinique par une TSH inférieure à 0.45 mUI/l avec un taux normal de T4L, après exclusion des participants prenant des médicaments pouvant perturber la thyroïde. Sur les 52'674 participants, 2188 (4.2%) avaient une hyperthyroïdie infra-clinique. Pendant un suivi de plus de 8 ans, 8527 participants sont décédés (dont 1896 de cause cardiovasculaire), 3653 sur 22'437 ont eu un événement cardiovasculaire et 785 sur 8711 ont développé une fibrillation auriculaire. Dans des analyses ajustées pour l'âge et le sexe, l'hyperthyroïdie infra-clinique était associée à une hausse de la mortalité de toute cause (hazard ratio [HR] 1.24, intervalle de confiance à 95% [IC] 1.06-1.46), de la mortalité cardiovasculaire (HR 1.29, IC 1.02-1.62), des événements cardiovasculaires (HR 1.21, IC 0.99- 1.46) ainsi qu'une hausse de l'incidence de fibrillation auriculaire (HR 1.68, IC 1.16-2.43). Les risques ne différaient pas significativement dans les analyses stratifiées selon l'âge, le sexe ou la présence de maladies cardiovasculaires préexistantes, et étaient similaires après ajustement multiple pour les facteurs de risque cardiovasculaire. Le risque de mortalité cardiovasculaire et de fibrillation auriculaire était plus élevé avec une TSH très basse (< 0.10 Ul/I) comparé à une TSH modérément abaissée (0.10-0.44 mUI/l, valeurs ρ for trend < 0.03). Conclusions et perspectives L'hyperthyroïdie infra-clinique est associée à un risque augmenté de mortalité de toute cause, de cause cardiovasculaire et de fibrillation auriculaire, avec un risque plus élevé quand la TSH est inférieure à 0.10 mUI/l. Ces résultats sont cohérents avec les dernières recommandations internationales conseillant de considérer un traitement de l'hyperthyroïdie infra-clinique pour les adultes de plus de 65 ans ou les patients avec maladie cardiaque, en particulier si la TSH est inférieure à 0.10 mUI/l. Toutefois, des études cliniques randomisées sont encore nécessaires pour prouver l'efficacité du traitement et déterminer si l'on devrait dépister les problèmes de thyroïde dans la population générale.

PURPOSE OF REVIEW: The safety and efficiency of trans catheter aortic valve implantation (TAVI) has been clearly demonstrated. In high-risk patients, the number of procedures is constantly increasing and in western European countries this procedure is employed in more than 30% of isolated aortic valve replacements. The literature, however, focusing on perioperative aortic root (AoR) rupture is rather limited to just a few reports. The aim of this review is to analyze the pathophysiology of AoR rupture during TAVI, stressing the implications of the morphology of the AoR for this devastating complication. RECENT FINDINGS: Currently, perioperative AoR rupture ranges between 0.5 and 1.5% during TAVI, with almost 100% mortality. Recently, valve oversizing and balloon dilatation in a calcified and small AoR were considered as the most important predictive factors for this complication. SUMMARY: The most fragile unit of the AoR is its anchoring substrate to the ostium of the left ventricle. This membranous structure is not involved in the degenerative process leading to aortic valve stenosis. Due to the TAVI and/or balloon dilatation of the calcium stationed on the three leaflets and their attachment, a lesion may result on this structure. And, as a consequence, there is rupture of the AoR.

BACKGROUND: Estimating current cancer mortality figures is important for defining priorities for prevention and treatment.Materials and methods:Using logarithmic Poisson count data joinpoint models on mortality and population data from the World Health Organization database, we estimated numbers of deaths and age-standardized rates in 2012 from all cancers and selected cancer sites for the whole European Union (EU) and its six more populated countries. RESULTS: Cancer deaths in the EU in 2012 are estimated to be 1 283 101 (717 398 men and 565 703 women) corresponding to standardized overall cancer death rates of 139/100 000 men and 85/100 000 women. The fall from 2007 was 10% in men and 7% in women. In men, declines are predicted for stomach (-20%), leukemias (-11%), lung and prostate (-10%) and colorectal (-7%) cancers, and for stomach (-23%), leukemias (-12%), uterus and colorectum (-11%) and breast (-9%) in women. Almost stable rates are expected for pancreatic cancer (+2-3%) and increases for female lung cancer (+7%). Younger women show the greatest falls in breast cancer mortality rates in the EU (-17%), and declines are expected in all individual countries, except Poland. CONCLUSION: Apart for lung cancer in women and pancreatic cancer, continuing falls are expected in mortality from major cancers in the EU.

Despite a sharp decline in the incidence of gastric cancer during the second half of the 20th century, this malignancy remains the second leading cause of cancer mortality in the world. The incidence and mortality rate of gastric cancer increase with age; at present, the median ages at diagnosis are 67 years for men and 72 years for women in the US. This article reviews and discusses current medical treatment options for both the general population and elderly gastric cancer patients. Management of localized gastric cancer has changed significantly over recent years. Adjuvant chemoradiation is not generally recommended outside the US. After decades of trials of adjuvant chemotherapy with inconclusive results, a significant survival benefit for perioperative combination chemotherapy - as compared with surgery alone - in patients with resectable or locally advanced gastro-oesophageal cancer was recently demonstrated in the UK MAGIC trial. A further large, randomized trial from Japan demonstrated a significant survival benefit for adjuvant chemotherapy with S-1 after D2 resection for gastric cancer. However, both trials are applicable only to the population in which the trials were conducted. Specific data on elderly patients are missing. For patients with metastatic disease, oral fluoropyrimidines, such as capecitabine, have been developed. In Asian patients, treatment with the oral fluoropyrimidine S-1 is safe and effective. Docetaxel, oxaliplatin and irinotecan have demonstrated activity against gastric cancer in appropriately designed, randomized, phase III trials and have increased the available treatment options significantly. In addition, according to preliminary data, trastuzumab in combination with chemotherapy has significantly improved activity when compared to chemotherapy alone in patients with human epidermal receptor (HER)-2-positive gastric and gastro-oesophageal cancers. Thus, therapeutic decisions in patients with advanced gastric cancer may be adapted to the molecular subtype and co-morbidities of the individual patient. Data from retrospective analyses suggest that oxaliplatin seems to be better tolerated than cisplatin in elderly patients.

To determine incidence and type of major cardiac adverse events in patients with mutated desmin (DES) gene, we retrospectively reviewed baseline medical information, and examined the long-term outcomes of 28 DES patients (17 men, baseline mean age=37.7±14.4 years [min=9, max=71]) from 19 families. Baseline studies revealed skeletal muscle involvement in 21 patients and cardiac abnormalities in all but one patient. Over a mean follow-up of 10.4±9.4 years [min=1, max=35], cardiac death occurred in three patients, death due to cardiac comorbidities in two, one or more major cardiac adverse events in 13 patients. Among the 19 patients with mild conduction defects at baseline, eight developed high-degree conduction blocks requiring permanent pacing. Cardiac involvement was neither correlated with the type of DES mutation nor with the severity of skeletal muscle involvement. Our study underscores that in DES patients in-depth cardiac investigations are needed to prevent cardiac conduction system disease.
