Validation of the London School of Hygiene (Rose) Questionnaire with objective measures of myocardial ischemia is incomplete. Therefore, we compared the Rose Questionnaire with exercise thallium-201 myocardial scintigraphy in 147 male and 97 female patients with chest pain referred for clinical exercise testing. Of those with "Rose Questionnaire angina", 26% of the females and 73% of the males had positive thallium-201 scans. Negative results on both the Rose Questionnaire and thallium-201 scintigraphy were observed in 71% of the females and 47% of the males. The sensitivity of the Rose Questionnaire was similar in females (41%) and males (44%). The specificity was 77% in males, while in females it was significantly lower at 56%. The specificity values reflect the higher (p less than 0.05) prevalence of "false positive" Rose Questionnaire results in females (75%) compared with males (27%). In addition, males had a greater (p less than 0.05) number of "false negative" results (53%) than females (29%). The accuracy of the Rose Questionnaire for myocardial ischemia was 0.19 in females, 0.48 in males, and 0.29 overall when including both males and females. Our results indicate a generally poor relationship between Rose Questionnaire angina and thallium-201 scintigraphy, an objective measure of myocardial ischemia in patients with chest pain referred to clinical exercise testing. Further, there are gender-specific differences in this relationship between the questionnaire and exercise thallium-201 imaging.

This cross-sectional study aimed to estimate the seroprevalence and the potential risk factors of Brucella infection among goats in family farms in the southern east of Algeria. A total of 196 sera samples were randomly collected from 59 family farms and tested in parallel by Rose Bengal test (RBT) and indirect ELISA (iELISA). A structured questionnaire was used to collect information on potential risk factors.

The American College of Obstetricians and Gynecologists provided updated guidance in 2021, recommending that reproductive health professionals should include discussion of environmental exposures with their patients. However, environmental health is seldom included in medical training, with endocrine-disrupting chemicals, such as phthalates-linked to adverse pregnancy outcomes-being among the least discussed. We developed a one-hour virtual educational intervention to train reproductive health professionals on the routes of phthalate exposure, potential associated health impacts, and suggestions on how to discuss exposure reduction with patients.

Home high-flow therapy during recovery from severe chronic obstructive pulmonary disease (COPD) exacerbation: a mixed-methods feasibility randomised control trial.

Introduction: Patients recovering from severe acute exacerbations of chronic obstructive pulmonary disease (AECOPD) have a 30-day readmission rate of 20%. This study evaluated the feasibility of conducting a randomised controlled trial to evaluate clinical, patient-reported and physiological effects of home high-flow therapy (HFT) in addition to usual medical therapy, in eucapnic patients recovering from AECOPD to support the design of a phase 3 trial.
Methods: A mixed-methods feasibility randomised controlled trial (quantitative primacy, concurrently embedded qualitative evaluation) (ISRCTN15949009) recruiting consecutive non-obese patients hospitalised with AECOPD not requiring acute non-invasive ventilation.
