Prognostic value of stress CMR and SPECT-MPI in patients undergoing intermediate-to-high-risk non-cardiac surgery.

Article Synopsis
- This study focused on how myocardial perfusion imaging (MPI) stress tests—specifically using stress cardiac magnetic resonance (sCMR) and single-photon emission computed tomography (SPECT-MPI)—affect the safety of high-risk patients undergoing non-cardiac surgery.
- It involved 1,590 patients with heart disease or significant cardiovascular risk factors, finding that those who underwent stress tests had fewer cardiac complications within 30 days post-surgery (1.2% vs. 3.4%).
- While both sCMR and SPECT-MPI reduced cardiac event rates equally, sCMR was shown to be more accurate for predicting the need for coronary artery revascularization.
The Effect of Previous Methylphenidate Use on Incidence of Stress Fractures in Military Recruits: A Retrospective Cohort.

Background: Previous research has detected an increased risk of stress fractures among subjects who reported previous use of methylphenidate. Conversely, stimulant medication use has been associated with traumatic fracture risk reduction, possibly because of the improved control of the underlying symptoms of attention deficit hyperactivity disorder (ADHD). The goal of this study was to investigate the effect of previous methylphenidate use on the incidence of traumatic and stress fractures among combat soldiers with previously treated and untreated ADHD.

The pathogenesis of melanomas emerging in plantar surfaces remains unclear; however, mechanical stress has been reported to increase the formation of melanomas. In this study, we conducted a multicenter retrospective analysis of 153 acral melanomas diagnosed between 2000 and 2015 in Taiwan. The male-to-female ratio of the patients in question was 1:1.

Background: This study aimed to identify factors from standard radiographs that contributed to the stability of the ankle mortise in patients with isolated supination-external rotation fractures of the lateral malleolus (OTA/AO 44-B).
Methods: Non-stress radiographs of the mortise and lateral views, without medial clear space widening or incongruity, were prospectively collected for 286 consecutive patients (mean age, 45 years [range, 16 to 85 years]), including 144 female patients (mean age, 50 years [range, 17 to 85 years]) and 142 male patients (mean age, 40 years [range, 16 to 84 years]) from 2 trauma centers. The radiographs were analyzed for fracture morphology by 2 orthopaedic surgeons, who were blinded to each other's measurements and to the results of external rotation stress radiographs (the reference for stability).
Aim: The aim of this study was to evaluate the prognostic value of normal and indeterminate patterns of cardiotocography in admission test (AT) and pregnancy outcome.
Material And Methods: A prospective study enrolled 818 intrapartum singleton pregnancies with gestational age of >34 weeks, in the latent phase and with intact membrane. Cases were divided into the high- and low-risk groups.
