Alcohol and nonlethal injuries: a Swiss emergency department study on the risk relationship between acute alcohol consumption and type of injury.

BACKGROUND: Acute alcohol consumption has been reported to be an important risk factor for injury, but clear scientific evidence on issues such as injury type is not available. The present study aims to improve the knowledge of the importance of alcohol consumption as an injury determinant with regards to two dimensions of the type of injury, namely the nature and the body region involved. METHODS: Risk relationships between two injury type components and acute alcohol use were estimated through multinomial and logistic regression models based on data from 7,529 patients-among whom 3,682 had injury diagnoses-gathered in a Swiss emergency department. RESULTS: Depending on the type of injury, between 31.1% and 48.7% of casualties report alcohol use before emergency department attendance. The multinomial regression models show that even low alcohol levels are consistently associated with nearly all natures of injury and body regions. A persistent dose-response effect between alcohol levels and risk associations was observed for almost all injury types. CONCLUSIONS: The results highlight the importance and consistency of the risk association between low and moderate levels of acute alcohol consumption and all types of injury. None of the body regions and natures of injury could pride on absence of association between alcohol and injury. Public health, prevention, and care implications are considered.

National, regional, and global trends in fasting plasma glucose and diabetes prevalence since 1980: systematic analysis of health examination surveys and epidemiological studies with 370 country-years and 2·7 million participants.

BACKGROUND: Data for trends in glycaemia and diabetes prevalence are needed to understand the effects of diet and lifestyle within populations, assess the performance of interventions, and plan health services. No consistent and comparable global analysis of trends has been done. We estimated trends and their uncertainties in mean fasting plasma glucose (FPG) and diabetes prevalence for adults aged 25 years and older in 199 countries and territories. METHODS: We obtained data from health examination surveys and epidemiological studies (370 country-years and 2·7 million participants). We converted systematically between different glycaemic metrics. For each sex, we used a Bayesian hierarchical model to estimate mean FPG and its uncertainty by age, country, and year, accounting for whether a study was nationally, subnationally, or community representative. FINDINGS: In 2008, global age-standardised mean FPG was 5·50 mmol/L (95% uncertainty interval 5·37-5·63) for men and 5·42 mmol/L (5·29-5·54) for women, having risen by 0·07 mmol/L and 0·09 mmol/L per decade, respectively. Age-standardised adult diabetes prevalence was 9·8% (8·6-11·2) in men and 9·2% (8·0-10·5) in women in 2008, up from 8·3% (6·5-10·4) and 7·5% (5·8-9·6) in 1980. The number of people with diabetes increased from 153 (127-182) million in 1980, to 347 (314-382) million in 2008. We recorded almost no change in mean FPG in east and southeast Asia and central and eastern Europe. Oceania had the largest rise, and the highest mean FPG (6·09 mmol/L, 5·73-6·49 for men; 6·08 mmol/L, 5·72-6·46 for women) and diabetes prevalence (15·5%, 11·6-20·1 for men; and 15·9%, 12·1-20·5 for women) in 2008. Mean FPG and diabetes prevalence in 2008 were also high in south Asia, Latin America and the Caribbean, and central Asia, north Africa, and the Middle East. Mean FPG in 2008 was lowest in sub-Saharan Africa, east and southeast Asia, and high-income Asia-Pacific. In high-income subregions, western Europe had the smallest rise, 0·07 mmol/L per decade for men and 0·03 mmol/L per decade for women; North America had the largest rise, 0·18 mmol/L per decade for men and 0·14 mmol/L per decade for women. INTERPRETATION: Glycaemia and diabetes are rising globally, driven both by population growth and ageing and by increasing age-specific prevalences. Effective preventive interventions are needed, and health systems should prepare to detect and manage diabetes and its sequelae. FUNDING: Bill & Melinda Gates Foundation and WHO.

Fièvre à répétition chez l'enfant: penser au syndrome de PFAPA [Periodic fever in children: keep in mind the PFAPA syndrome]

Les maladies autoinflammatoires font partie du diagnostic différentiel de l'état fébrile à répétition chez l’enfant. Ces maladies sont caractérisées par des poussées inflammatoires sans cause évidente. Certaines de ces maladies, comme la Fièvre méditerranéenne familiale, ont une origine génétique et nécessitent un traitement régulier pour éviter des conséquences graves à long terme. Le syndrome de PFAPA est la plus fréquente des fièvres récurrentes et son diagnostic se base sur des critères diagnostiques peu précis. Son traitement reste controversé. La prednisone en dose unique permet d'interrompre la poussée et l'amygdalectomie peut induire une rémission dans une majorité des cas. The autoinflammatory diseases should be considered in the differential diagnosis of recurrent fever in childhood. These diseases are characterized by inflammatory episodes without an evident cause. Some of these diseases, like the Familial Mediterranean Fever, have a genetic origin and need a chronic treatment to avoid severe complications on the long term. PFAPA syndrome is the most frequent cause of recurrent fever and is diagnosed based on unspecific criteria. The treatment is still controversial. One dose of Prednisone is able to interrupt the flare and tonsillectomy may induce a remission in the majority of the cases

Life cycle of Triatoma ryckmani (Hemiptera: Reduviidae) in the laboratory, feeding patterns in nature and experimental infection with Trypanosoma cruzi

A cohort initiated with 121 eggs, yielding 105 first instar nymphs (eclosion rate: 86.78%), allowed us to observe the entire life cycle of Triatoma ryckmani under laboratory conditions (24ºC and 62% relative humidity), by feeding them on anesthetized hamsters. It was possible to obtain 62 adults and the cycle from egg to adult took a mean of 359.69 days with a range of 176-529 days (mortality rate of nymphs: 40.95%). Mean life span of adults was of 81 days for females and 148 days for males. The developmental periods of 4th and 5th nymphs were longer than those of the other instars. This suggests that young siblings have a better chance of taking a hemolymph meal from older ones, in order to survive during fasting periods during prolonged absences of vertebrate hosts from natural ecotopes. The stomach contents of 37 insects showed blood from rodents (15 cases), lizards (7 cases), birds (6 cases) and insect hemolymph (7 cases). Out of 10 insects fed by xenodiagnosis on a Trypanosoma cruzi infected mouse, all but one became infected with the parasite.

Evaluation pré-TAVI : comparaison entre le scanner cardiaque et l'échocardiographie.

Objectifs: Comparer le CT et l'échocardiographie cardiaques pour l'évaluation pré-interventionnelle des patients éligibles pour un remplacement aortique percutané (TAVI). Matériels et méthodes: Trente patients (15F/15H, âge 84±7y) éligibles pour un TAVI par voie transfémorale (n=15) ou transapicale (n=15) ont bénéficié d'un CT pré-procédural pour évaluer le diamètre (DCT) valvulaire aortique. Une échographie trans-thoracique pré et post-TAVI a été effectuée pour évaluer le gradient trans-valvulaire (Gmax) et la différence (ΔGmax), et une échographie trans-oesophagienne (ETO) pour confirmer le diamètre valvulaire (DUS). Le test-t de Student, le test de Lin (ρc) et le test de Bland-Altman (LOA) ont été utilisés pour les comparaisons. Résultats: Le DCT était similaire chez les patients bénéficiant d'un TAVI transfémoral ou transapical (22.9±3.0mm vs. 21.2±1.5mm,p=0.06). Le DCT était plus bas que le DUS (22.2±2.6mm vs. 23.3±2.1mm,p=0.017) et l'agrément entre DCT et DUS était modéré (ρc=0.62,différence moyenne=-1.1±1.9mm, 95%LOA:-4.8-2.6). Le Gmax pré-TAVI était similaire chez les patients ayant un TAVI transfémoral ou transapical (70.8±33.7 vs. 86.3±24.0mmHg,p=0.17). Le Gmax post-TAVI était plus bas que le Gmax pré-TAVI (78.5±29.7 vs. 16.8±5.1mmHg,p<0.001). Le ΔGmax était similaire pour les TAVI transfémoraux ou transapicaux (46.3±28.6 vs. 70.4±25.1 mmHg,p=0.05). Conclusion: Le CT cardiaque représente une alternative non-invasive à l'ETO pour l'évaluation pré-TAVI du diamètre valvulaire aortique.

Evaluación económica de la monoterapia con tocilizumab frente a adalimumab en artritis reumatoide.

BACKGROUND Tocilizumab (TCZ) was superior to adalimumab (ADA), as monotherapy, in reducing signs and symptoms of adult rheumatoid arthritis (RA) when methotrexate (MTX) treatment is poorly tolerated or inappropriate. The aim of the study was to analyze the cost-effectiveness of TCZ vs ADA in these patients. METHODS Economic evaluation of the cost per response or remission of TCZ vs ADA from ADACTA (time horizon: 24 weeks). Clinical response criteria ACR or disease remission criteria, DAS28. PERSPECTIVE National Health System. The costs included (acquisition, administration and monitoring of medicines; € 2012) were obtained from Spanish sources. Simple univariate sensitivity analyzes were performed. RESULTS ACR20, ACR50 and ACR70 response rates with TCZ and ADA were obtained in 65% and 49.4% (p <0.01), 47.2% and 27.8% (p <0.01); and 32.5% and 17.9% (p <0.01) of patients, respectively. DAS28 remission occurred in 39.9% and 10.5%, respectively (p <0.0001). The cost per response was lower with TCZ than with ADA (ACR20: € 8,105 and € 11,553; ACR50: € 11,162 and € 20,529; ACR70: € 16,211 and € 31,882) respectively. The cost of DAS28 remission was € 13,204 and € 54,352, respectively. Treatment with TCZ was dominant (more effective, with lower costs vs ADA) in all scenarios analyzed. CONCLUSIONS According to this analysis, in Spain TCZ monotherapy is an efficient strategy vs ADA for treating RA patients intolerant to MTX or in which there is inappropriate response.

Detection of Oropouche virus segment S in patients and inCulex quinquefasciatus in the state of Mato Grosso, Brazil

This study aimed to investigate the circulation of Orthobunyavirus species in the state of Mato Grosso (MT) Brazil. During a dengue outbreak in 2011/2012, 529 serum samples were collected from patients with acute febrile illness with symptoms for up to five days and 387 pools of female Culex quinquefasciatuscaptured in 2013 were subjected to nested-reverse transcription-polymerase chain reaction for segment S of the Simbu serogroup followed by nucleotide sequencing and virus isolation in Vero cells. Patients (5/529; 0.9%) from Cuiabá (n = 3), Várzea Grande (n = 1) and Nova Mutum (n = 1) municipalities were positive for the S segment of Oropouche virus (OROV). Additionally, eight/387 Cx. quinquefasciatuspools were positive for the segment, with a minimum infection rate of 2.3. Phylogenetic analysis indicated that all the samples belong to the subgenotype Ia, presenting high homology with OROV strains obtained from humans and animals in the Brazilian Amazon. The present paper reports the first detection of an Orthobunyavirus, possibly OROV, in patients and in Cx. quinquefasciatus mosquitoes in MT. This finding reinforces the notion that arboviruses frequently reported in the Amazon Region circulate sporadically in MT during dengue outbreaks.

Photodynamic Diagnosis in Non-Muscle-Invasive Bladder Cancer

Objective This paper reviews the development and clinical validation of photodynamic diagnosis (PDD) of bladder cancer. Methods The authors reviewed the literature on the development of PDD, in particular the evidence for the clinical efficacy of hexaminolevulinate PDD in the diagnosis of bladder cancer. Results After initial work on ultraviolet cystoscopy following oral tetracycline, the focus of PDD research shifted to the use of synthetic porphyrins. First, the prodrug delta-aminolevulinic acid (ALA) was shown to cause a transient but significant accumulation of protoporphyrin IX (PpIX) in malignant or premalignant bladder tissue. Excitation by blue light leads to PpIX fluorescence (red), which distinguishes tumour from normal tissue (blue). Hexaminolevulinate (HAL, Hexvix), an ester of ALA, was then developed and has greater bioavailability and stability than the parent compound. It has been approved for clinical use in the diagnosis of bladder cancer. Clinical studies have shown that HAL PDD detects tumours, including carcinoma in situ (CIS), that are missed by conventional white-light cystoscopy. Conclusions HAL PDD is a valuable aid to the detection of bladder tumours, including CIS.

Influence of structural heterogeneities and of large scale topography on imbricate gravitational rock slope failures: New insights from 3-D physical modeling and geomorphological analysis

Initial topography and inherited structural discontinuities are known to play a dominant role in rock slope stability. Previous 2-D physical modeling results demonstrated that even if few preexisting fractures are activated/propagated during gravitational failure all of those heterogeneities had a great influence on mobilized volume and its kinematics. The question we address in the present study is to determine if such a result is also observed in 3-D. As in 2-D previous models we examine geologically stable model configuration, based upon the well documented landslide at Randa, Switzerland. The 3-D models consisted of a homogeneous material in which several fracture zones were introduced in order to study simplified but realistic configurations of discontinuities (e.g. based on natural example rather than a parametric study). Results showed that the type of gravitational failure (deep-seated landslide or sequential failure) and resulting slope morphology evolution are the result of the interplay of initial topography and inherited preexisting fractures (orientation and density). The three main results are i) the initial topography exerts a strong control on gravitational slope failure. Indeed in each tested configuration (even in the isotropic one without fractures) the model is affected by a rock slide, ii) the number of simulated fracture sets greatly influences the volume mobilized and its kinematics, and iii) the failure zone involved in the 1991 event is smaller than the results produced by the analog modeling. This failure may indicate that the zone mobilized in 1991 is potentially only a part of a larger deep-seated landslide and/or wider deep seated gravitational slope deformation.

The association of aldosterone with obesity-related hypertension and the metabolic syndrome.

Overweight and obesity are associated with arterial hypertension. Given the large increase in the obesity prevalence worldwide, the number of obese patients with hypertension is likely to increase substantially in the near future. Overweight and obese patients are exposed to an important metabolic and cardiovascular risk. The understanding of the mechanisms linking obesity to hypertension is important for specific prevention and therapy in this population. There is some evidence that obesity is associated with an increased aldosterone level. To date, 2 mechanisms may explain the interaction of fat tissue with the renin-angiotensin-aldosterone system, and therefore explain, in part, obesity-related hypertension. First, human adipose tissue produces several components of the renin-angiotensin-aldosterone system, mainly adipose tissue-derived angiotensinogen. Second, increased fatty acid production in the obese patient, especially nonesterified fatty acids, might stimulate aldosterone production, independent of renin. A better understanding of these mechanisms might have implications for the management of hypertension in overweight and obese patients. Because aldosterone also is associated with blood glucose and blood lipids, selective aldosterone blockade may represent a particularly attractive therapeutic strategy in obese patients with a clustering of cardiovascular risk factors.
