Quality of life assessment and HIV infection: A review

In the last few years, survival of patients infected with human immunodeficiency virus (HIV) has been improved because of a decreased incidence of some opportunistic complications attributable to prophylactic treatments and antiretroviral drugs. The impact of these agents should also be reflected in the quality of life (QoL) of patients. We have reviewed this topic with an emphasis on different types of measurements such as Q-TWIST, MOS and the Spitzer score which seem to be most appropriate for this patient population. We do not think that a special type of assessment should be designed for HIV-infected persons. It would be less time-consuming to improve already existing validated scores focusing on HIV infection. QoL in intravenous drug users with HIV should be evaluated more often.     

Determinants of health counseling practices in hospitals: the patient's perspective

We conducted a survey of 518 patients who had been admitted to three hospitals for selected medical, surgical, and obstetrical conditions. All patients came from the same city. One of the hospitals had put forward health promotion and disease prevention as a formal goal. Almost 40% of the respondents reported that they received health counseling during their hospital stay. Logistic regression analyses revealed that medical care processes and organizational factors were more important than patient characteristics in determining health counseling. The only patient characteristic that was positively related to health counseling was "perceived poor health status." Favorable conditions for the development of health counseling included having an attending physician different from the one who treated the patient before entering the hospital, an adequate number of physician visits, and a longer length of stay. Being admitted to a medical ward rather than a surgical or an obstetrical ward also was associated with more frequent health counseling. No significant differences were found among hospitals. Finally, having a general practitioner rather than a specialist as attending physician did not make a difference. These findings support the view that although hospitals have an important and legitimate role to play in health promotion, organizational and institutional obstacles to implementing such practices must not be ignored.     

The importance of dietary sodium: the time has come for a public health intervention

In recent years, many studies have been published regarding the link between sodium intake and high blood pressure. Canadian, American and WHO Guidelines on the treatment of hypertension all indicate salt reduction as an efficient non-pharmacologic recommendation. However, due to the lack of clear and specific Canadian legislation on food labelling, consumers are not able to make informed choices of food products on the basis of salt content. The time has come for public health experts to join this debate.     

The diluting effect of medical work groups on feedback efficacy in changing physician's practice

Feedback intervention has been advocated as a successful method to modify the way that physicians practice medicine. However, most studies concerned with modifying physician profiles have focused on interns and residents. The results presented here concern regular staff and therefore provide a better basis for generalization. Over a 2.5-year period, we analyzed the use of clinical resoucces by physicians practicing in four medical specialties in two hospitals. Hierarchical multiple regression models were used to control case mix in order to identify the specific effects attributable to feedback. The information failed to modify the physicians' practice profiles. Our results suggest that this failure is related to the organization of inpatient medical practice as a group effort. This mode of practice has a negative effect on feedback efficacy. First, it weakens one of the main feedback mechanisms, that is personal identification with the data. Second, it probably generates mutual adjustment among physicians, thus eliminating practice variations at the source.     

Malignant transformation of craniofacial fibrous dysplasia: a systematic review of overall survival

The incidence of malignant transformation of fibrous dysplasia (FD) is very rare. Thus, the available knowledge of its characteristics, management, and survival is scarce. Here, we present a systemic review of fibrous dysplasia that had undergone malignant transformation. A comprehensive search was performed on PubMed electronic database. The survival rates and hazard ratios of age, gender, past history of previous radiotherapy, type of FD, and treatment were collected from the published articles and analyzed. Forty-eight cases were eligible for inclusion in the study. Patient’s age, gender, past history radiotherapy, and type of FD did not influence the overall survival (OS). The Kaplan Meier analysis showed that the patients who had not received any treatment had poor prognosis with a median survival of 4 months. The patients that received surgery had significantly longer OS than that in the biopsy group. The prognosis of malignant transformation of FD is relatively poor, and surgery is the optimal treatment of choice. Nevertheless, the efficacy of postoperative adjuvant therapy to patient OS is still undefined.     

Characteristic and prognosis of acute large vessel occlusion in anterior and posterior circulation after endovascular treatment: the ANGEL registry real world experience

There were limited studies comparing the anterior (AC) and posterior (PC) circulation acute ischemic strokes (AIS). Our study aimed to evaluate distinct features of AC and PC strokes regarding clinical, vascular risk, pathogenesis and outcome factors after endovascular procedures. This multicenter prospective study registered 873 patients with acute large occlusion of anterior circulation stroke (ACS) and posterior circulation stroke (PCS). Patients who underwent endovascular procedures were included in this study. The differences in ACS and PCS regarding baseline characteristics, post-operative intracranial hemorrhage and outcomes were evaluated. A total of 741 patients were included in the data analysis. Intravenous thrombolysis (31.5%), atrial fibrillation (22.7%) and stent thrombectomy (82.4%) were more frequently observed in ACS patients. While higher NIHSS score, hypertension (67.6%) and balloon angioplasty (20.7%) were more prevalent in PCS patients. Symptomatic intracranial hemorrhage was more common in ACS (7.4% vs 2.8%). However, a 3-month follow-up outcomes were better in ACS with higher functional independence and low mortality rate than PCS (46.8% vs 30.3% and 16.4% vs 33.8%, respectively, P?<?0.01). In this large prospective study, there were significant differences in the pathogenesis of stroke and treatment procedure between ACS and PCS which influence the clinical outcome. These findings could lead to a tailored clinical procedures and treatment strategies to improve the prognosis in both groups.
