Adolescent smoking is a major public health problem. While the socioeconomic status (SES) of the neighbourhood and that of the family are known to play a role in smoking onset and progression, it is not clear whether it modifies the association between parental influences and adolescent behaviour. The purpose of this study is to investigate family correlates of adolescent smoking experimentation and to explore the modifying role of socioeconomic context and European geographical area in a sample of European adolescents. This is a secondary analysis of the baseline survey of the European Drug Addiction Prevention (EU-Dap) trial which took place in seven European countries and involved 7079 students. School SES was used as indicator of socioeconomic context. European countries were aggregated in two geographical areas: North-Central and South. The associations between parental, family factors, and adolescents smoking experimentation were analysed through multilevel mixed-effect logistic regression models, stratified by school SES and European geographical area. Parental smoking, permissiveness towards tobacco, family conflicts, problematic relationships, low connectedness, and low parental control were significantly associated with adolescent smoking experimentation. Paternal smoking was a stronger correlate of adolescent smoking in low SES schools, while maternal smoking in high SES schools. Parental permissiveness was a stronger correlate in low SES schools. Family conflicts and low parental control were correlates only in low SES schools. The associations did not substantially differ between European geographical areas, with the exception of parental smoking that was a stronger correlate in the North, and parental control that was a correlate only in the South of Europe. To reduce inequalities in tobacco-related outcomes, prevention efforts in low socioeconomic contexts appear to be a public health priority. Parental smoking, permissiveness, family relationships, and connectedness should be addressed in preventive programs.
The transduction mechanism of the inner ear and the transmission of nerve impulses along the auditory way are highly dependent
upon the cochlear oxygen supply. Several studies have considered the possibility that obstructive sleep apnea–hypopneas during
sleep can interfere with these processes, and the results are not uniform. The aim of the study is to evaluate the auditory
function in adult patients affected by severe obstructive sleep apnea syndrome (OSAS). 相似文献
We have little knowledge about the evolution of emphysema, and relatively little is understood about its evolution in relation
to smoking habits. This study aims to assess the evolution of emphysema in asymptomatic current and former smokers over 2
years and to investigate the association with subjects’ characteristics. The study was approved by our Ethics Committee and
all participants provided written informed consent. 相似文献
Information regarding advanced cancer patients followed at home who are admitted to the hospital in the last days of life are lacking. The aim of this study was to assess the characteristics of patients who were hospitalized in the last days of life after being assisted by a home palliative care team. The secondary outcome was to identify possible risk factors for hospitalization. The charts were analyzed of a consecutive sample of advanced cancer patients admitted to hospital wards in the last days of life after being followed at home by a palliative care team. Of 550 consecutive patients followed at home, 138 (25.1 %) were admitted to the hospital. Younger patients were more likely to die in the hospital. In a logistic risk analysis adjusted for age, patients with lung and head–neck cancer were more likely to die in the hospital. Patients having a female relative or a female consort as a caregiver were more likely to die at home. CAGE-positive patients (7.25 %), and patients with a shorter period of home assistance were more likely transported to hospital before dying (p = 0.00 and p < 0.024, respectively). The most frequent reason for hospital admission was dyspnea. Admission was more frequent to the oncology ward. Patients who were admitted to the hospital died after a mean of 10.2 days (SD 8.2, range 0–40). This study provides preliminary data on the risk factors of hospitalization at the end of life for advanced cancer patients followed at home. 相似文献
OBJECTIVES: The aim of this study was to assess the potential value of hand-carried ultrasound (HCU) devices in the diagnosis and follow-up of patients with pleural effusion (PE) after cardiac surgery. METHODS: Seventy consecutive patients were evaluated at bedside early after cardiac surgery, in the upright sitting position, using an HCU device on hospital admission and every 3 days until hospital discharge. The posterior chest wall was scanned along the paravertebral, scapular, and posterior axillary lines. For each hemithorax, an effusion index was derived as the sum of the intercostal spaces between the lower and upper limits of the PE along the lines of scanning, divided by 3. A standard chest radiograph was performed in all patients on hospital admission and at hospital discharge, and was qualitatively scored (0, absent; 1, small; 2, large PE). The findings of the HCU device and radiograph were compared using kappa statistics and the Kruskal-Wallis test. RESULTS: A chest ultrasound was feasible in all patients (mean [+/- SD] time, 5 +/- 2 min). Compared with the chest ultrasound, a physical examination showed a sensitivity of 69% and a specificity of 77%. On hospital admission, the HCU device detected a PE in 72 of 140 hemithoraxes. Agreement with the finding of the radiograph was 76% (kappa = 0.52). In 15 hemithoraxes, the HCU device revealed a PE that had not been diagnosed using the radiograph. Conversely, in 18 hemithoraxes a PE that had been diagnosed with a radiograph was not confirmed by the HCU device. The correlation between ultrasound and radiographic scores was statistically significant (p < 0.001). At hospital discharge, a PE was present in 31 of 140 hemithoraxes according to the findings of the HCU device, and in 38 of 140 hemithoraxes according to the findings of the radiograph (agreement, 78%; kappa = 0.44). CONCLUSIONS: In patients early after cardiac surgery, HCU devices allow rapid PE detection and improve the clinical diagnosis. Compared to a radiograph, this method offers the unique advantage of the bedside evaluation of patients without the need for radiation exposure. 相似文献
Abstract: Background/Aims: Hepatitis C virus (HCV) related disease follows a long, benign course and most affected patients have mild disease. Liver biopsy is mandatory to grade and stage the disease. Characteristic, though non-specific, HCV histological lesions such as bile duct damage and steatosis have been singled out but their association with non-histological parameters has not been completely defined. Our aim was to study the relationships among these histological lesions and clinical, biochemical, functional and virological characteristics in a group of Northern Italian patients with chronic hepatitis. Methods: We studied 172 patients with HCV-related chronic hepatitis. Patients were divided into groups on the basis of histology including bile duct damage and steatosis. Clinical, biochemical, functional and virological profiles were related to histological findings. Results: Histological grading and staging of disease increased as the age of patients increased. Steatosis was present in 70% of our patients and was related to a higher degree of fibrosis and to decreased functional activity. The prevalence of bile duct damage was 20%. This lesion was present in older patients with higher staging and impaired liver function. Biochemically it was associated with an increase in aspartate aminotransferase, gammaglutamyltranspeptidase, alkaline phosphatase, and total bilirubin. Conclusions: In the population we studied, HCV chronic hepatitis was predominantly a mild disease. Moreover both steatosis and bile duct damage were also mild. Steatosis was associated with fibrosis and this might influence liver metabolic function. Bile duct lesions were found in older patients with advanced disease showing biochemical evidence of cholestasis. The molecular role HCV might play in the pathogenesis of these histological features should be addressed in further studies. 相似文献
