Objectives. We examined obesogenic dietary practices among Latino and Asian subgroups of children living in California.Methods. We analyzed 2007, 2009, and 2011–2012 California Health Interview Survey data to examine the differences in dietary practices among Mexican and non-Mexican Latino children and 7 ethnic subgroups of Asian children. We used multivariable regression to examine the sociodemographic factors associated with specific dietary practices.Results. Latino subgroups of children had few differences in obesogenic dietary practices, whereas Asian subgroups of children exhibited significant differences in several obesogenic dietary practices. Korean and Filipino children were more likely than Chinese children to consume fast food and have low vegetable intake. Filipino children, followed by Japanese children, had the most obesogenic dietary practices compared with Chinese children, who along with South Asian children appeared to have the least obesogenic dietary practices. In general, income, education, and acculturation did not explain the dietary differences among Asian groups.Conclusions. Our findings suggest the need to disaggregate dietary profiles of Asian and Latino children and to consider nontraditional sociodemographic factors for messaging and counseling on healthy dietary practices among Asian populations.Dietary practices among pediatric racial and ethnic minority groups highlight possible contributions to the nation’s significant obesity disparities. High consumption of sugar- sweetened beverages (SSBs) and fast food and low consumption of fruits and vegetables have been found among Latino and African American children compared with White children.1–4 These dietary differences have been associated with environmental factors such as access to fresh foods and social factors such as family income, education level, and acculturation. Many of these factors have been understudied among Asian children. This gap in the literature is problematic given the emerging evidence that Asian children have notable differences in dietary practices compared with White children and that Asian Americans with the same body mass index (BMI; defined as weight in kilograms divided by the square of height in meters) are at a higher risk for cardiovascular diseases and type 2 diabetes than non-Hispanic Whites.5–8 Furthermore, children of various Asian and Latino ethnic groups with distinct historical, migration, and social contexts are generally grouped together in research analyses, making it difficult to understand the ethnicity-specific salient roles that education, income, and acculturation may play in specific dietary practices.9,10Acculturation has been described as both a protective factor and a risk factor for healthy dietary practices among immigrants. For example, acculturation among Latinos has been associated with higher consumption of fruits and vegetables but also with higher rates of fast food and sugary food consumption in both pediatric and adult Latino populations.11–13 Less is known about the role of acculturation in dietary practices among Asian and Latino ethnic subgroups.5,6,14,15 We examined dietary practices within ethnic subgroups of Latino and Asian children and the associated role of sociodemographic factors. On the basis of the thin literature that has examined dietary practices among Latino subgroups of children, we hypothesized that children of Mexican descent would have healthy dietary practices compared with other Latino groups and that Asian ethnic groups of children would show a wide variety of dietary practices. In addition, we hypothesized that acculturation, after controlling for education and income, would have an independent effect on dietary practices for all ethnic groups of children. 相似文献

The present report describes giant atrial thrombi that were treated with thrombolysis in a community hospital. Two patients with giant atrial thrombi whose treatment involved complications are presented. Both patients developed cardiogenic shock and were treated unsuccessfully with thrombolysis. Because thrombolysis of giant thrombi may be ineffective, patients in this situation may require surgery. 相似文献

OBJECTIVES: This study aimed to separate proposed mechanisms for segmental ischemic mitral regurgitation (MR), including left ventricular (LV) dysfunction versus geometric distortion by LV dilation, using models of acute and chronic segmental ischemic LV dysfunction evaluated by three-dimensional (3D) echocardiography. BACKGROUND: Dysfunction and dilation-both mechanisms with practical therapeutic implications-are difficult to separate in patients. METHODS: In seven dogs with acute left circumflex (LCX) coronary ligation, LV expansion was initially restricted and then permitted to occur. In seven sheep with LCX branch ligation, LV expansion was also initially limited but became prominent with remodeling over eight weeks. Three-dimensional echo reconstruction quantified mitral apparatus geometry and MR volume. RESULTS: In the acute model, despite LV dysfunction with ejection fraction = 23 +/- 8%, MR was initially trace with limited LV dilation, but it became moderate with subsequent prominent dilation. In the chronic model, MR was also initially trace, but it became moderate over eight weeks as the LV dilated and changed shape. In both models, the only independent predictor of MR volume was increased tethering distance from the papillary muscles (PMs) to the anterior annulus, especially medial and posterior shift of the ischemic medial PM, measured by 3D reconstruction (r2 = 0.75 and 0.86, respectively). Mitral regurgitation volume did not correlate with LV ejection fraction or dP/dt. CONCLUSIONS: Segmental ischemic LV contractile dysfunction without dilation, even in the PM territory, fails to produce important MR. The development of MR relates strongly to changes in the 3D geometry of the mitral apparatus, with implications for approaches to restore a more favorable configuration. 相似文献

Abstract An improved method of inducing diabetes in dogs was developed. This method included 90% pancreatectomy, 2 mg/kg streptozotocin
(STZ) perfused into pancreaticoduodenal artery, and the fixation suture of the duodenum to the costo-abdominal wall. Vasopressin
injection administered to the animals before surgery reduced bleeding. All dogs used in this procedure survived and became
diabetic. One month after the procedure the pancreatic islets were reduced in volume and the number compared with pancreas
tissue obtained during the surgery. Acinar tissue remained with a normal histology, and exocrine function maintained the physiological
parameters, except for a soft faecal consistency. We conclude that this procedure is effective in inducing experimental diabetes
in dogs. 相似文献

Catheter-based interventions to improve mitral valve function are dependent on anatomic and functional information provided by noninvasive imaging to plan, perform, and evaluate each intervention. In this review we highlight the importance of imaging guidance for catheter-based interventions on prosthetic mitral valves, surgical rings, and native valve annular calcification. Both repair and replacement procedures are discussed. We review the general features common to this collection of procedures and discuss specific imaging issues and concerns for each procedure. Figures and intraprocedural videos emphasize central messages using case examples. 相似文献

Patients with acute myocardial infarction (AMI) often have multiple co-morbidities that influence outcome. We sought to evaluate the impact of peripheral vascular disease (PVD) on the outcome of patients with AMI treated with primary angioplasty. We evaluated 3,716 patients with AMI who underwent emergency catheterization with planned primary angioplasty in the Primary Angioplasty in Myocardial Infarction trials. Patients with a history of PVD (claudication, stroke, or transient ischemic attack) were compared with patients without PVD. Of the 3,716 patients, 394 (10.6%) had PVD and were older, more often women, and more frequently had a history of diabetes mellitus, hypertension, smoking, congestive heart failure, angina, myocardial infarction, and coronary revascularization. They presented more often with a heart rate >100 beats/min, Killip class >1, lower ejection fraction, and multivessel disease. No difference was found in stent use, final percentage of stenosis, or Thrombolysis In Myocardial Infarction 3 flow. Patients with PVD had a twofold increased in-hospital mortality (5.3% vs 2.6%, p = 0.0021). The difference remained significant at 1 month, 6 months, and 1 year (12.6% vs 6%, p < 0.0001). In multivariate logistic regression analysis, a history of PVD was an independent predictor of in-hospital mortality and death at 1 year (odds ratio 1.64, 95% confidence interval 1.04 to 2.57, p = 0.032). In conclusion, patients with AMI with PVD have increased co-morbidities and higher mortality despite treatment with primary angioplasty. The presence of PVD is an independent predictor of in-hospital mortality and death at 1 year. 相似文献

A large proportion of patients with hypertension need a second drug to reach satisfactory control of blood pressure (BP), but there are few well-designed controlled trials comparing the efficacy of drugs added as a second option. In a double-blind randomized clinical trial, 82 patients with uncontrolled BP, receiving hydrochlorothiazide 25 mg daily, were selected to receive amiloride 2.5-5 mg/day (n = 39) or enalapril 10-20 mg/day (n = 43). Ambulatory blood pressure monitoring (ABPM) was done before and after 12-weeks of treatment. Office BP was measured in the 4(th), 8(th), and 12(th) weeks. The doses of amiloride and enalapril were doubled in the fourth week, and propranolol was added in the 8th week if office BP was above 140/90 mm Hg. There was a greater BP reduction in patients treated with enalapril. The ABPM delta values between the groups were 3.6 +/- 2.2, 3.9 +/- 2.2, and 1.1 +/- 2.7 mmHg for 24-h, daily, and nightly systolic blood pressure, respectively, favoring enalapril. For diastolic blood pressure (DBP), the deltas were 1.7 +/- 2.0, 3.2 +/- 1.5, and 1.2 +/- 1.9 mmHg, respectively (p = 0.039 for daily DBP). Office SBP decreased more and sooner in patients allocated to enalapril (p = 0.003). More patients taking amiloride required propranolol to control BP (p = 0.035). Potassium increased 0.3 mEq/L on the average in both groups. Cough, albeit predominantly mild, was reported more frequently by participants treated with enalapril. We conclude that enalapril is more effective than amiloride to lower BP of patients on hydrochlorothiazide with uncontrolled BP. 相似文献
