恢复体验类型在调节紧张相关健康状况的作用分析

目的评价不同恢复体验类型(RE)的护士群体职业紧张、身心健康、职业生命质量的差异,分析评价恢复体验类型在调节紧张相关健康状况的作用。方法对某市7家三甲医院298名在岗护士,以单纯随机抽样的方法抽取研究样本,采用工作内容问卷(JCQ)测量职业紧张、中文版恢复体验问卷(REQ-C)测量恢复体验水平、聚类分析方法区分恢复体验类型、职业生命质量问卷(QWL7-32)测量紧张相关健康状态。结果聚类分析将298名护士分为充分型、中间型和缺乏型三种RE类型;三种类型的护士心理健康和职业生命质量得分存在差异(P0.01)。不同RE类型的对象,其心理健康与职业生命质量水平随紧张水平变化的趋势不同;因变量为心理健康得分的多元线性回归分析中,结果显示相对于缺乏型来说,充分型的β值为-2.48(P0.05),RE类型为心理健康的独立影响因素。结论不同恢复体验类型对心理健康、职业生命质量的调节作用存在差异。     

The safety of pharmacologic treatment for pediatric obesity

Introduction: Pediatric obesity is a serious public health concern. Five medications have been approved by the Food and Drug Administration (FDA) for chronic weight management in adults with obesity, when used as an adjunct to lifestyle modification. Orlistat is the only FDA-approved medication for pediatric patients aged 12 years and above.

Areas covered: This paper summarizes safety and efficacy data from clinical trials of weight loss medications conducted among pediatric samples. Relevant studies were identified through searches in PubMed.

Expert opinion: Orlistat, as an adjunct to lifestyle modification, results in modest weight losses and may be beneficial for some pediatric patients with obesity. However, gastrointestinal side effects are common and may limit use. In adults taking orlistat, rare but severe adverse events, including liver and renal events, have been reported. Recent pediatric pharmacokinetic studies of liraglutide have demonstrated similar safety and tolerability profiles as found in adults, with gastrointestinal disorders being the most common adverse events. Clinical trials are needed of liraglutide, as well as other medications for obesity, that systematically evaluate their risks and benefits in pediatric patients.     

Oral fungal and bacterial infections in HIV-infected individuals: an overview in Africa

Oral opportunistic infections developing secondary to human immunodeficiency virus (HIV) infection have been reported from the early days of the epidemic and have been classified by both the EC-Clearinghouse and the World Health Organisation (WHO). Among the fungal infections, oral candidiasis, presenting in African HIV-infected patients has been sporadically documented. We review the literature with respect to candidal carriage, oral candidiasis prevalence and the predictive value of oral candidiasis for a diagnosis of underlying HIV disease in African HIV-infected patients. The use of oral candidiasis as a marker of disease progression, the species of yeasts isolated from the oral cavity in Africa and the resistance of the yeasts to antifungal agents and treatment regimens are discussed. Orofacial lesions as manifestations of the systemic mycoses are rarely seen in isolation and few cases are reported in the literature from Africa. In spite of the high incidence of noma, tuberculosis, chronic osteomyelitis and syphilis in Africa, surprisingly there have been very few reported cases of the oral manifestations of these diseases in HIV-positive individuals. Orofacial disease in HIV-infected patients is associated with marked morbidity, which is compounded by malnutrition. The authors indicate specific research areas, initially directed at the most effective management strategies, which would complete data in this important area.     

Effects of inhalational bronchodilator treatment during noninvasive ventilation in severe chronic obstructive pulmonary disease exacerbations

Purpose

To study the effects of withdrawing noninvasive ventilation (NIV) used during acute exacerbation of chronic obstructive pulmonary disease for the delivery of aerosolized medications on physiologic parameters and dyspnea sensation.

Methods

We measured accessory muscle use, dyspnea sensation, heart rate (HR), respiratory rate (RR), blood pressure (BP), and arterial blood gases during NIV, 10 minutes after cessation of NIV (with oxygen), after nebulization with salbutamol (5 mg) and ipratropium (500 μg), and again, on restitution of NIV.

Results

We studied 19 patients (3 women; mean [±SD] age, 72 [± 9] years) with a mean postbronchodilator forced expiratory volume in 1 second 40% (±12) of predicted. Baseline RR (23/min), HR (98/min), BP (121/62 mm Hg), Spo₂ (95%), pH (7.31 [±0.06]), Paco₂ (65 [±12] mm Hg), and Borg score (1.8 [±0.43]) were recorded. There were no significant changes in physiologic parameters and oxygenation between NIV and nebulization periods. The only physiologic changes observed were increase in systolic BP (SBP, P = .012) and HR (P = .003) after nebulization. However, significant decrease in oxygen saturation (P = .009) and increase in SBP (P = nonsignificant) were observed between NIV and oxygenation phases.

Conclusion

Short-term cessation of NIV for nebulization treatment did not result in distress, discomfort, or physiologic instabilities. The only detectable changes were increase in SBP and HR, probably due to the systemic adrenergic effects of salbutamol.

Adherence of fresh and stored granulocytes to endothelial cells. Effect of storage temperature

Granulocyte (PMN) concentrates collected for transfusion to septic, neutropenic patients are stored in the blood bank for various periods of time before they are given. Current methods of blood bank storage of PMN concentrates are associated with impaired in vitro PMN chemotaxis (CTX) and in vivo recovery and circulation kinetics after 24 hours of storage. This suggested the possibility that PMN may become hyperadherent during storage. To test this hypothesis, PMN concentrates were harvested and stored at both 22 and 6 degrees C and their adherence properties to relevant biologic surfaces, endothelial cell (EC) monolayers, and extracellular matrix (ECM) derived from endothelium were measured. Adherence was measured within 4 hours of collection and after 24 and 48 hours of storage. The aggregation properties of fresh and stored PMN were also studied. The adherence of fresh, unstimulated PMN to EC and ECM (31 +/- 5% and 34 +/- 4%, respectively) increased significantly after storage for 24 hours (EC = 41 +/- 8%; ECM = 43 +/- 4%) at 22 degrees C. F-Met-Leu-Phe (FMLP) stimulated the adherence of fresh PMN (EC = 37 +/- 4%; ECM = 42 +/- 4%; p less than 0.05). The adherence of PMN stored at 22 degrees C was further stimulated by FMLP (EC = 46 +/- 6%; ECM = 50 +/- 4%). PMN stored at 6 degrees C had significantly higher adherence than PMN stored at 22 degrees C, and the percentage of increase in adherence induced by FMLP was attenuated in PMN stored at 6 degrees C.(ABSTRACT TRUNCATED AT 250 WORDS)

Sensitive skin evaluation in the Japanese population

Sensitive skin syndrome was first described in 1977; however, no robust study has been carried out to evaluate its prevalence in Japan. A national representative sample of the Japanese population over the age of 18 years was taken. Individuals were questioned by telephone and selected according to the quota method. When asked “Do you have a sensitive skin?”, 52.84% of men and 55.98% of women answered “rather sensitive” or “very sensitive”. There was no significant difference (P = 0.22) between the two sexes. The non‐response rate among respondents was zero, suggesting that the term “sensitive skin” held a meaning for the majority of the population. Concerning questions about the onset of a rash, tingling or irritation in the presence of various factors, such as emotional issues, cold, heat, sun, dry air, air‐conditioning, water, air pollution and temperature variations, respondents with rather sensitive or very sensitive skin responded “yes” more often than others: approximately three‐times more often for water (18.97%/6.15%), air pollution (39.29%/12.45%) and warm climatic conditions (29.74%/9.8%). To our knowledge, this epidemiological study is the first to focus on sensitive skin among Japanese people of this century. It is of particular interest for two reasons: (i) it was conducted on a representative sample of the Japanese population; and (ii) the methodology used was identical to that used for sensitive skin assessment studies conducted in Europe and the USA, making it possible to draw certain comparisons.
