A review of interprofessional training wards: Enhancing student learning and patient outcomes.

Background: In an interprofessional training ward (ITW), students from different health professions collaboratively perform patient care with the goal of improving patient care. In the past two decades, ITWs have been established world-wide and studies have investigated their benefits. We aimed to compare ITWs with respect to their logistics, interprofessional learning outcomes and patient outcomes. Methods: We explored PubMed, CINAHL, Web of Science and EMBASE (1990-June 2017) and included articles focusing on interprofessional, in-patient training wards with student teams of medical and other health professions students. Two independent reviewers screened studies for eligibility and extracted data. Results: Thirty-seven articles from twelve different institutions with ITWs were included. ITWs world-wide are organized similarly with groups of 2-12 students (i.e. medical, nursing, physiotherapy, occupational therapy, and pharmacy) being involved in patient care, usually for a period of two weeks. However, the type of clinical ward and the way supervisors are trained differ. Conclusions: ITWs show promising results in short-term student learning outcomes and patient satisfaction rates. Future ITW studies should measure students' long-term interprofessional competencies using standardized tools. Furthermore, a research focus on the impact of ITWs on patient satisfaction and relevant patient care outcomes is important.

Cardiovascular and metabolic characteristics of infertile Chinese women with PCOS diagnosed according to the Rotterdam consensus criteria.

Polycystic ovary syndrome (PCOS) is strongly associated with metabolic abnormalities in Western women. However, data from other populations and geographical regions are scarce. This study evaluated cardiovascular and metabolic risk factors in Chinese infertile women diagnosed with PCOS using the 2003 Rotterdam consensus criteria. A total of 615 women representing the four PCOS phenotypes (oligo- or anovulation (AO)+hyperandrogenism (HA)+polycystic ovaries (PCO), AO+HA, AO+PCO and HA+PCO) underwent standardized metabolic screening including a 75g oral glucose tolerance test. All groups presented with similar reproductive characteristics, with the only difference being a significantly higher Ferriman-Gallwey score for hirsutism (P=0.01) in the subgroup characterized by HA+PCO. Overall, the prevalence of metabolic syndrome was 6.4%, with no difference among the four groups (range of 2.3-12.2%). Metabolic syndrome was associated with body mass index (P<0.001), waist/hip ratio (P=0.002), index of insulin resistance (P=0.005) and fasting insulin (P=0.009) in multivariate analysis. Compared with Caucasians and Chinese women in Westernized societies, mainland Chinese women with PCOS have a low risk of metabolic syndrome and its presence does not vary across the specific PCOS phenotypes.

Indicators for metabolic disturbances in anovulatory women with polycystic ovary syndrome diagnosed according to the Rotterdam consensus criteria.

BACKGROUND: Polycystic ovary syndrome (PCOS) is associated with metabolic abnormalities. It is debated whether all women with PCOS should be screened for metabolic abnormalities as these may vary with PCOS phenotype, age and ethnicity. The aims of this study were to assess the prevalence of metabolic abnormalities in Dutch anovulatory PCOS women and to define criteria for metabolic screening. METHODS: Anovulatory patients, diagnosed with PCOS according to the Rotterdam consensus criteria, underwent metabolic screening. Through stepwise multivariate analysis patient characteristics associated with metabolic syndrome (MetS) and insulin resistance (IR) were evaluated for their use as selection parameters for metabolic screening. RESULTS: Overall, prevalence of MetS and IR was 15.9% (n = 25) and 14% (n = 22), respectively, in 157 PCOS women (age 29.0 +/- 4.8 years, BMI 26.1 +/- 6.7 kg/m(2)). Anovulatory hyperandrogenic women (with or without polycystic ovaries) had more often MetS and IR (with, 20.8 and 19.8%; without, 100 and 40%, respectively) than non-hyperandrogenic PCOS women (0 and 1.8%; P < 0.001). Waist circumference >83.5 cm along with increased free androgen index (FAI) had the most powerful association with the presence of MetS and IR (area under the receiver operating characteristic curve 0.912) and offered a reduction in the necessity of screening for metabolic derailments of about 50%. CONCLUSIONS: The hyperandrogenic PCOS phenotypes are highly linked to the presence of MetS and IR in Dutch PCOS women. Waist circumference combined with FAI was identified as an efficient combination test to select those PCOS women who should be screened for the presence of MetS and/or IR.

Cardiometabolic abnormalities in the polycystic ovary syndrome: pharmacotherapeutic insights.

The polycystic ovary syndrome (PCOS) affects 5-10% of all premenopausal women. It is diagnosed by a combination of oligo-amenorrhea and hyperandrogenism (NIH criteria) or by the presence of two out of three of: oligo-amenorrhea, hyperandrogenism, polycystic ovaries on ultrasound (Rotterdam criteria). PCOS is associated with obesity, insulin resistance and dyslipidemia. Different patterns of dyslipidemia can be present, both in lean and obese PCOS. Low HDL-cholesterol, with or without elevated TG, is the most prominent lipid abnormality. In addition, smaller HDL and LDL particles and elevated postprandial TG responses are reported. Hyperandrogenism, anovulation and insulin resistance affect multiple steps in lipid metabolism in PCOS, as will be discussed. Surrogate markers for atherosclerosis are consistently abnormal in PCOS, while studies on clinical CVD endpoints are limited and non-conclusive. The (pharmaco-) therapy of dyslipidemia in PCOS will be discussed. In addition, the effects of other PCOS related (pharmaco-) therapies, primarily aimed at hyperandrogenism, anovulation or insulin resistance, on lipid metabolism will be addressed.

[Women and cardiovascular disease]. / Vrouwen en hart- en vaatziekten.

More women die of cardiovascular disease than men; in women, cardiovascular mortality is 1.5 times greater than cancer mortality. The pathophysiology of cardiovascular disease has female-specific aspects such as fragile coronary arteries and microvascular ischaemia. Women with acute coronary syndromes are more likely to present with atypical symptoms such as dyspnoea, nausea or fatigue. With regard to diagnostic tests in women, exercise ECG can be difficult to interpret and a normal coronary angiogram does not exclude coronary heart disease. Myocardial perfusion scintigraphy may be considered for high-risk women who are clinically suspected of having coronary heart disease and have a normal or inconclusive exercise ECG and angiogram. Women are less likely to be treated according to guidelines than men, and their prognosis after a myocardial infarction or a coronary intervention is worse. Female-specific aspects such as gestational hypertension and diabetes allow for early detection and treatment of women at risk for cardiovascular disease.

Dutch medical oath.

In the first part of this article, the booklet Dutch Medical Oath is reviewed. The content of the new oath is discussed as are the reasons for revision of the previous version of the oath. This is followed by a short history of the oath. In the second part of the article the oath is compared with the seven competencies of a medical specialist. The new oath contains elements of six of these seven competencies. This demonstrates that the oath is in keeping with the new medical educational demands.

Gender differences in diagnosis and treatment of coronary artery disease from 1981 to 1997. No evidence for the Yentl syndrome.

AIMS: The aim of the present clinical study was to evaluate whether gender-related differences existed as regards the extent and localization of coronary artery lesions in patients with angiographically documented coronary artery disease, and whether these angiographic findings would lead to differences in further management. METHODS AND RESULTS: Over a 16-year period (1981-1997) we evaluated 1894 patients (1526 men, 368 women) with angiographically documented coronary artery disease (luminal stenosis >/=60%). For each patient the coronary angiographic results and subsequent revascularization procedures (percutaneous transluminal coronary angioplasty or coronary artery bypass graft surgery) were analysed. The study period was divided into the early angioplasty years (1981 to 1989) and the current angioplasty years (1990-1997). No gender differences in extent and localization of coronary angiographic lesions were observed. In men and women the incidence of single-vessel disease was 42% and 40%, two-vessel disease 27% and 27%, three-vessel disease 26% and 24%, and left main disease 5% and 8%, respectively (P=ns). Localization of disease in men and women was 36% and 39% for the left anterior descending coronary artery, 34% and 32% for the right coronary artery, and 27% and 26% for the left circumflex coronary artery, respectively (P=ns). There was a significant shift from multi-vessel disease towards single-vessel disease in both men and women (both P<0.001). As to subsequent management, a significant gender difference in favour of women was observed (P=0.021). Over time, the number of angioplasty procedures increased significantly from 11.6% to 23.2% for men (P<0.001), and for women from 17.6% to 28.0% (P=0.025), whereas the number of coronary artery bypass procedures decreased in men from 34.9% to 29. 5% (P=0.024) and in women from 42.6% to 30.6% (P=0.019). Referral to angioplasty (n=535) and coronary artery bypass surgery (n=616) in relation to the extent of the disease did not show any gender bias in favour of men. CONCLUSIONS: Our angiographic findings did not show significant gender differences as regards the extent and localization of coronary artery disease in patients with angiographically documented coronary artery disease. More importantly, no substantial evidence could be found for under-referral of women to subsequent therapeutic management. Therefore our study questions the presence of Yentl syndrome in the current era.

Delayed chylomicron remnant clearance in subjects with heterozygous familial hypercholesterolaemia.

OBJECTIVES: To study the role of the LDL receptor in the clearance of chylomicron remnants in humans. DESIGN: Chylomicron remnant clearance was studied in five untreated subjects with heterozygous familial hypercholesterolaemia (FH) and nine normolipidaemic controls, by oral retinyl palmitate-fat loading tests. Fasting plasma triglycerides (TG), which are important determinators of chylomicron and remnant clearance, were not significantly different between FH (1.76+/-0.32 mmol L(-1), mean+/-SEM) and controls (1.26+/-0.18 mmol L(-1). Chylomicrons (Sf > 1000) and their remnants (Sf < 1000) were separated by flotation and their clearance was estimated by calculating the area under the 24 h-retinyl palmitate curve (AUC-RP). The factors determining chylomicron and remnant clearance were studied by univariate and multiple regression analysis. RESULTS: Triglyceride clearance in plasma, Sf > 1000 fractions and Sf < 1000 fractions was not significantly different between FH subjects and controls. In subjects with heterozygous FH, chylomicron remnant clearance was two-fold delayed (AUC-RP, 49.39+/-11.61 h.mg L(-1) compared to controls (27.45+/-3.95 h.mg L(-1); P = 0.048). Moreover, 28.4% higher fasting plasma TG in FH resulted in 44.4% higher areas under the remnant-curves compared to controls. The clearance of chylomicron RP was associated to plasma apo E (beta = 0.73, P = 0.011), plasma LDL cholesterol (beta = 0.62, P = 0.018) and plasma TG (beta = 0.58, P = 0.029). The clearance of remnant RP was associated to the diagnosis (FH vs. non-FH), but not to the well-known determinants of remnant clearance like plasma TG. CONCLUSIONS: The clearance of chylomicrons and large remnants isolated in the Sf > fraction depends primarily on the apo B, E (LDL) receptor and to a lesser extent on plasma triglycerides. The clearance of smaller chylomicron remnants isolated in the Sf < 1000 depends to a large extent on the apo B, E (LDL) receptor.

Estrogens and postprandial lipid metabolism.

Women with angiographically proven coronary heart disease (CAD) had higher postprandial concentrations of small chylomicron-remnants, measured as IDL apo B48, than women without CAD. Fasting TG concentrations were not different and within the normal range. Thus, the postprandial concentration of small chylomicron-remnants could identify women at high CAD risk within a normolipidemic population. Replacement therapy with 17beta-estradiol improved the clearance of chylomicron-remnants by 41% and attenuated the postprandial reduction in HDL-cholesterol by 66%. This improvement in postprandial lipid metabolism can explain part of the protective effect of estrogens against CAD.
