Assessing the information desire of patients with advanced cancer by providing information with a decision aid,which is evaluated in a randomized trial: a study protocol

Background  

There is a continuing debate on the desirability of informing patients with cancer and thereby involving them in treatment decisions. On the one hand, information uptake may be hampered, and additional stress could be inflicted by involving these patients. On the other hand, even patients with advanced cancer desire information on risks and prognosis. To settle the debate, a decision aid will be developed and presented to patients with advanced disease at the point of decision making. The aid is used to assess the amount of information desired. Factors related to information desire are explored, as well as the ability of the medical oncologist to judge the patient's information desire. The effects of the information on patient well-being are assessed by comparing the decision aid group with a usual care group.     

Prevalence and risk indicators of oral mucosal lesions in an urban population from South Brazil

Oral Diseases (2011) 17 , 171–179 Objective: The objective of the study was to assess the prevalence of oral mucosal lesions (OML) and to perform a multivariable risk assessment of demographic, socioeconomic, behavioral, and oral risk indicators for its occurrence in an urban population in South Brazil. Methods: This cross‐sectional study selected 1586 subjects (719M/867F, age: 14–104 years) using a multistage probability sampling strategy (65.1% response rate). Prevalence, odds ratios (OR), and confidence intervals (95% CI) were calculated accounting for the survey design. Results: Leukoplakia and lichen planus were observed in 1.01% and 1.02% of subjects, respectively. In the multivariable analysis, these lesions were significantly associated with moderate/heavy smoking (OR = 9.0, 95% CI = 2.1–39.1) and heavy drinking (OR = 2.0, 95% CI = 1.1–3.7). Candidiasis and proliferative lesions were observed in 14.09% and 3.80% of the subjects, respectively. These lesions were significantly associated with female gender (OR = 2.2, 95% CI = 1.5–3.2 and OR = 1.7, 95% CI = 1.0–2.8), older age (OR = 22, 95% CI = 8.0–60.8 and OR = 8.9, 95% CI = 3.4–23.7), and low socioeconomic status (OR = 1.9, 95% CI = 1.0–3.5 and OR = 3.0, 95% CI = 1.2–7.2). Conclusions: This population is in need of OML prevention and treatment. Future studies should validate the findings that premalignant lesions are causally related to smoking and alcohol consumption, and that other OML are associated with socioeconomic‐demographic disparities in this and similar populations.     

Pulmonary flow profile and distensibility following acute pulmonary embolism

Objective

Proof of concept study evaluating CMR as screening tool for chronic thromboembolic pulmonary hypertension (CTEPH) in patients treated for acute pulmonary embolism (PE).

Materials and methods

Right and left ventricular function of 15 consecutive patients treated for PE and 10 consecutive patients in whom PE was excluded was estimated at baseline by cardiac CT and at 6 months follow-up by CMR. Additionally, during the follow-up visit, pulmonary artery (PA) hemodynamics were studied by CMR and the presence of pulmonary hypertension by echocardiography.

Results

CT measured right ventricular ejection fraction (RVEF) was lower in patients with PE compared to patients without PE at time of diagnosis (median 47%, interquartile range 39-53 vs. 55%, 52-58; p = 0.014). After 6 months follow up, the RVEF between patients treated for PE and patients without PE were not statistically significant different (55%, 52-60 versus 54%, 51-57; p = 0.57), as were distensibility index (0.18 ± 0.18 versus 0.25 ± 0.18, p = 0.20), mean velocity (14.1 ± 3.9 cm/s versus 14.0 ± 2.5 cm/s, p = 0.81), peak velocity (86.5 ± 22 cm/s versus 89.6 ± 13 cm/s, p = 0.43) and time to peak PA blood flow velocity (142 ± 49 ms versus 161 ± 29 ms, p = 0.14). One patient was diagnosed with CTEPH and CMR revealed poor right systolic function, decreased PA distensibility and flow velocity, and a systolic notch in the PA flow profile consistent with persistent PA obstruction.

Conclusion

In this small series, right ventricular performance and PA flow profiles of patients treated for 6 months after PE are equivalent to those parameters in normal patients.     

Quality of interhospital transport of the critically ill: impact of a Mobile Intensive Care Unit with a specialized retrieval team

Introduction  

In order to minimize the additional risk of interhospital transport of critically ill patients, we started a mobile intensive care unit (MICU) with a specialized retrieval team, reaching out from our university hospital-based intensive care unit to our adherence region in March 2009. To evaluate the effects of this implementation, we performed a prospective audit comparing adverse events and patient stability during MICU transfers with our previous data on transfers performed by standard ambulance.     

The real experience of patients after liver transplantation in intensive care unit

We aimed to explore the real experience of patients after liver transplantation in the intensive care unit (ICU).Objective sampling method was used to select patients transferred to the ICU in 10 hospitals in Zhuhai from May 2018 to August 2020. Patients need liver transplantation due to advanced liver cancer and decompensated cirrhosis. The eligibility criteria of patients mainly included liver transplant patients who were clear-minded and willing to participate in the study and had stayed in ICU. Phenomenological research methods and in-depth interviews were used in this qualitative study.The results showed that the true experience of patients after liver transplantation during ICU stay was summarized into four themes. The strengths of our qualitative research are that we can find the trend from a phenomenon through interviews and other methods to provide a directional foundation for future quantitative research. Its limitations are that it requires a lot of manpower and time, and its objectivity and universality are limited.Hospitalization experience in the ICU may lead to many negative experiences for liver transplant patients. Nurses should fully understand and pay attention to the psychological changes in patients. Nurses should take effective targeted measures to reduce or eliminate patients’ fear of ICU stay and promote rehabilitation.     

Dimensionality and scale properties of the Edinburgh Depression Scale (EDS) in patients with type 2 diabetes mellitus: the DiaDDzoB study

Background

Depression is a common complication in type 2 diabetes (DM2), affecting 10-30% of patients. Since depression is underrecognized and undertreated, it is important that reliable and validated depression screening tools are available for use in patients with DM2. The Edinburgh Depression Scale (EDS) is a widely used method for screening depression. However, there is still debate about the dimensionality of the test. Furthermore, the EDS was originally developed to screen for depression in postpartum women. Empirical evidence that the EDS has comparable measurement properties in both males and females suffering from diabetes is lacking however.

Methods

In a large sample (N = 1,656) of diabetes patients, we examined: (1) dimensionality; (2) gender-related item bias; and (3) the screening properties of the EDS using factor analysis and item response theory.

Results

We found evidence that the ten EDS items constitute a scale that is essentially one dimensional and has adequate measurement properties. Three items showed differential item functioning (DIF), two of them showed substantial DIF. However, at the scale level, DIF had no practical impact. Anhedonia (the inability to be able to laugh or enjoy) and sleeping problems were the most informative indicators for being able to differentiate between the diagnostic groups of mild and severe depression.

Conclusions

The EDS constitutes a sound scale for measuring an attribute of general depression. Persons can be reliably measured using the sum score. Screening rules for mild and severe depression are applicable to both males and females.     

环氧合酶抑制剂与心血管事件的发生和预防

2004年,罗非昔布（万络）因致心血管疾病风险而撤市。市场上能增加心血管疾病风险的相关药物和环氧合酶（COX-2）抑制剂以及非选择性非甾体抗炎药（NSAID）也遭到质疑。本文论述是否新的证据能改进现有的临床实践和监管条例。过多的抑制COX-2会增加心血管疾病的发生风险,除非同时对血小板血栓素合成的抑制达95%以上,这可通过全血分析检测。最近研究证实,对乙酰氨基酚（扑热息痛）也是一种COX-2选择性抑制剂。流行病学调查指出,对乙酰氨基酚作为一种易得的非处方药物,也存在增加心血管事件的风险。目前尚无足够证据认为罗非昔布的替代药品是安全的。对NSAID的药品监管及处方应遵循“首要不伤害”的预警性原则,药品应强制性加注此类药物心血管风险的告示,以警示处方者和患者。     

同型半胱氨酸—糖尿病血管病变的新型危险因素

同型半胱氨酸（Hcy）是蛋氨酸代谢中间产物,是一种含硫基的氨基酸。1964年Gibson等首先报道高同型半胱氨酸血症与血管性疾病和血栓形成相关,1969年Mcully提出Hcy可能与动脉粥样硬化有关。随着近30年的深入研究,众多资料表明高Hcy血症（hHcy）是心脑血管病变的一个独立危险因素。
