China is a sexually conservative country compared with Western countries. To evaluate the psychological characteristics of Chinese erectile dysfunction (ED) patients, we conducted a cross‐sectional study of 153 ED outpatients. Patients were interviewed with the Structured Interview on Erectile Dysfunction (SIEDY) for pathogenic quantification. ED was measured by International Index of Erectile Function (IIEF). Depression and anxiety were evaluated with 9‐item Patient Health Questionnaire (PHQ‐9) and 7‐item Generalised Anxiety Disorder Scale (GAD‐7) respectively. Most patients (74.5%) were <40 years old. IIEF‐5 were significantly correlated with SIEDY scale 3 (r = .16, p = .040) and GAD‐7 (p = .15, p = .033). The SIEDY scale 1 increased with age, but the IIEF‐5, SIEDY scale 3, PHQ‐9 and GAD‐7 decreased with age. A negative correlation was observed between ED and psychological stress, which conflicts with many Western‐country studies. Younger patients were characterised by milder ED but more psychological stress, while older patients were characterised by worse ED but less psychological stress. Which may be responsible for the conflicting result. Meanwhile, the much younger age distribution among Chinese ED outpatients may indicate that quite a few older ED patients (≥40 years) in China do not seek outpatient service which should merit more attention.
Radiographic angles are used to assess the severity of hallux valgus deformity, make preoperative plans, evaluate outcomes after surgery, and compare results between different methods. Traditionally, hallux valgus angle (HVA) has been measured by using a protractor and a marker pen with hardcopy radiographs. The main objective of this study is to compare HVA measurements performed using a smartphone and a traditional protractor. The secondary objective was to compare the time taken between those two methods. Six observers measured major HVA on 20 radiographs of hallux valgus deformity with both a standard protractor and an Apple iPhone. Four of the observers repeated the measurements at least a week after the original measurements. The mean absolute difference between pairs of protractor and smartphone measurements was 3.2˚. The 95% confidence intervals for intra-observer variability were AE3.1˚for the smartphone measurement and AE3.2˚for the protractor method. The 95% confidence intervals for inter-observer variability were AE9.1˚for the smartphone measurement and AE9.6˚for the protractor measurement. We conclude that the smartphone is equivalent to the protractor for the accuracy of HVA measurement. But, the time taken in smartphone measurement was also reduced.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
