Question: Context: The normal anterior translation of the articular surface of the distal humerus with respect to the humeral diaphysis facilitates elbow flexion. We hypothesize that there is a correlation between anterior translation of the distal humeral articular surface and flexion after open reduction and internal fixation (ORIF) of a fracture of the distal humerus.', 'Two independent observers evaluated 141 lateral radiographs of patients more than 6 months after fracture of the distal humerus and 155 lateral radiographs of patients without injury of the distal humerus. The distance between the most anterior point of the distal humerus articular surface, perpendicular to the humeral shaft, from the anterior border of the distal part of the humeral diaphysis, was measured on lateral radiographs as a percentage of the width of the humeral shaft.', 'The technique of measuring anterior translation of the distal humeral articular surface had good intra- and interobserver reliability. The most anterior point of the distal humeral articular surface lies an average of 11.7 mm (range, 6.8 to 17.0 mm) in front of the most anterior border of the humeral shaft in normal distal humeri, which represents 62% of the humeral shaft diameter (range, 33% to 91%). There was a limited but significant correlation between flexion and anterior translation as a percentage of the humeral shaft diameter in distal humeri after fracture that was maintained in multivariable statistical models.
Answer: Using a reproducible technique for measuring anterior translation of the distal humerus, there was a correlation between anterior translation of the distal humeral articular surface and elbow flexion after ORIF. Although the weakness of the correlation emphasizes that limitation of elbow flexion after ORIF of a distal humerus fracture is multifactorial, reduced anterior translation of the distal humeral articular surface might be a contributing factor.

Answer: Is loss of anterior translation of the distal humeral articular surface associated with decreased elbow flexion?


Question: Context: Observational and clinical studies suggest different responses upon sex hormone replacement therapy in ischaemic heart disease. Few studies, however, have examined the impact of oestrogen receptor-dependent mechanisms on the extent of injury after myocardial infarction (MI). Therefore, we set out to evaluate the effect of oestrogen (E2) replacement on infarct size and remodelling, and the respective role of the oestrogen receptors (ER)alpha and -beta in this process, using ERalpha- and ERbeta-deficient mice.', 'Wild type (WT) (ERalpha(+/+) and ERbeta(+/+)), ERalpha-deficient (ERalpha(-/-)) and ERbeta-deficient (ERbeta(-/-)) mice were ovariectomized and subsequently supplemented with E2 or placebo using subcutaneous 60-day release pellets. MI was induced by left coronary artery ligation. Two weeks following MI, haemodynamic function was assessed and infarct size was determined.', 'There was no significant difference in infarct size between E2- or placebo-treated WT (ERalpha(+/+) and ERbeta(+/+)) mice. Surprisingly, E2 treatment did result in smaller infarct sizes in ERalpha(-/-) mice, but increased the infarct size in ERbeta(-/-) mice. Increase of the left ventricular mass post-MI was significantly larger in the E2-treated ERalpha(-/-) animals compared with placebo-treated animals. E2 treatment also significantly increased post-MI mortality in ERalpha(+/+), ERbeta(+/+) and ERalpha(-/-) animals, but not in ERbeta(-/-) mice.
Answer: Although E2 modulates the infarct size in ERalpha(-/-), it also appears to be responsible for the higher mortality following MI. ERbeta appears to be the receptor involved in the modulating effects of E2 in the infarcted heart.

Answer: Does oestrogen modulate cardiac ischaemic remodelling through oestrogen receptor-specific mechanisms?


Question: Context: Elevated levels of cardiometabolic markers are characteristic of normal pregnancy, however, insulin resistance and increased glucose, triglyceride, and cholesterol levels can adversely influence maternal and child health. Diet is a modifiable behaviour that could have significant impact on maternal cardiometabolic levels during pregnancy. We investigated the association between dietary patterns and cardiometabolic markers (glucose, insulin, insulin resistance (HOMA-IR), triglycerides, and cholesterol) during pregnancy.', 'Data from the Pregnancy, Infection, and Nutrition prospective cohort study (2000-05) was used (n = 513). Diet was assessed using a food frequency questionnaire. Dietary patterns were derived using latent class analysis (LCA) and the Dietary Approaches to Stop Hypertension (DASH) diet. Linear regression was used to examine the dietary patterns-cardiometabolic markers association during pregnancy.', 'Three dietary patterns evolved from the LCA characterised by high intakes of: (1) hamburgers, hot dogs, bacon, French fries, fried chicken, white bread, and soft drinks; (2) some vegetables, fruit juice, refined grains, mixed dishes, processed meat, and empty calorie foods; and (3) fruits, vegetables, whole grains, low-fat dairy, breakfast bars, and water. After adjustment for potential confounders including prepregnancy body mass index, a diet consistent with Latent Class 3 was negatively associated with maternal insulin (μU/mL: β = -0.12; 95% CI -0.23, -0.01) and HOMA-IR (β = -0.13; 95% CI -0.25, -0.00). Additionally, DASH scores within Tertile 3 (higher dietary quality) were also negatively associated with maternal triglycerides (mg/dL).
Answer: The study findings suggest an association between maternal dietary patterns and several cardiometabolic markers during pregnancy.

Answer:
Are maternal Dietary Patterns Associated with Lower Levels of Cardiometabolic Markers during Pregnancy?
