Background: Congestive heart failure is the leading cause of hospitalization in the elderly. Little is known about gender effect on baseline characteristics and in-hospital outcome in patients admitted with acute heart failure. Our purpose was to study the gender effect on in-hospital mortality in acute heart failure patients. Methods and Results: A prospective study [143 patients, 67 men (73.9 ± 13.8 years old) and 76 women (77.8 ± 10.1 years old) (p = 0.059)] followed in-hospital outcome of patients with acute heart failure admitted to the hospital. Clinical parameters included body mass index (BMI), ankle brachial index (ABI), left ventricular ejection fraction (LVEF), re-admissions within 1 year, and in-hospital mortality. The gender effects that were studied included height, BMI, smoking, coronary artery disease, LVEF and mortality: in total, 9 (6.3%) patients died, of them 8 (10.5%) women and 1 (1.5%) man. Women were shorter (p < 0.001), had a higher BMI (p = 0.053), reported less frequently on current smoking (p < 0.001), had lower prevalence of coronary artery disease (p = 0.016), had a better LVEF (p = 0.02), but still, had a higher mortality rate (p = 0.026). The only variables independently affecting in-hospital mortality in women were height and recurrent admissions. When we tested for the effect of height and recurrent admissions on mortality only among females by a multivariate analysis height inversely and independently affected in-hospital mortality (p = 0.024), as well as recurrent admissions (p = 0.031). Conclusions: In-hospital mortality was significantly higher in women compared with men admitted with acute heart failure. Among females, the only independent variables that affected mortality were low stature and recurrent admissions.

慢性阻碍性肺疾病及其他肺机能障碍是比较重要的医学难题。大量儿童患有诸如哮喘之类的疾病。现代生活导致与肺气肿、石棉肺、肺癌之类肺疾病有关的污染增加。肺机能障碍的基本诊断工具是听诊、即分析在胸壁听到的声信号。听诊为医师提供与一些肺及气道阻碍而产生的异常噪声的声源及位置有关的定量信息。常规听诊使用简单听诊器,人工分析,方法简便,但仅仅是定性的、主观的。

以以色列南部Seder Boker地区采集的粘壤土样品为研究对象。在室内利用ASD Field Spec 3型高光谱仪获取土壤的原始光谱,在进行数据预处理和不同数学变换后,共获取了4种光谱指标:光谱反射率(REF)、倒数之对数(LR)、一阶微分(FDR)和去包络线(CR)。采用偏最小二乘回归法(PLSR)、逐步回归法(SR)和岭回归法(RR)构建了基于不同指标的土壤含水率高光谱反演模型,并对反演结果进行精度验证与比较。结果表明:REF-PLSR模型在所有回归模型中的反演与预测效果均为最优(R2c=0.990,R2p=0.987),在逐步回归模型和岭回归模型中,LR-SR(R2c=0.981,R2p=0.971)、LR-RR(R2c=0.975,R2p=0.979)均为最佳模型。对于其他3种指标,虽然逐步回归法和岭回归法的建模效果较偏最小二乘回归法略有下降,但R2c均大于0.9,R2p均大于0.8,RPD均大于2.5,RMSE均小于0.03,模型仍具有较好的反演效果;逐步回归法和岭回归法均实现了模型的简化,但岭回归法采用有偏估计从而提高了模型的稳健性,且实现了波段的优选(用于建模的波段数仅为全光谱的0.3%)。粘壤土土壤含水率LR-RR高光谱反演模型的建立为高光谱模型的优化、土壤含水率的快速测定提供了途径。

AIM: To determine parental knowledge about acute otitis media(AOM) and its antibiotic therapy, antibiotic resistance and the willingness to comply with the watchful waiting(WW) approach in primary care settings in southern ***: The study was conducted in 3 primary care clinics and the pediatric emergency room of Soroka University Medical Center. Questionnaires(20 questions on education background, previous AOM experience, knowledge on antimicrobial resistance and attitude vs the WW approach) were filled by 600 parents(150 at each centers) of children < 6 years of ***: Mothers represented 69% of parents; 2% had an education of < 10 school years, 46% had high-school education and 17% had an academic degree. 69% parents reported previous experience with AOM and 56% thought that antibiotics represent the only treatment for AOM. Knowledge on bacterial resistance to antibiotics was reported by 57% of the parents; 86% parents were willing to accept/probably accept the WW approach for their children. Logistic regression analysis revealed a significant association between parental education and knowledge about bacterial resistance to antibiotics and that previous experience with AOM was significantly associated with reluctance to accept the WW approach. More parents with knowledge on bacterial resistance were willing to accept the WW approach compared with parents without such knowledge. No correlation was found between the education level and willingness to accept the WW approach. CONCLUSION: A significant correlation was found between previous parental education and experience with AOM and the knowledge about antibiotic use, bacterial resistance and acceptance of the WW approach.
