Testosterone replacement therapy and cardiovascular risk factors modification.

Hypogonadism in males is associated with increased atherosclerotic disease. Physiologically, testosterone appears to have both positive and negative effects on the cardiovascular system. Testosterone decreases angina and may improve the cardiac healing response after myocardial infarction. Testosterone enhances function in males with heart failure (HF). Testosterone causes water retention and oedema is common in older persons. Oedema should not be used to diagnose HF in older persons. Studies in older persons with HF and frailty have shown a non-statistically lower mortality rate compared to those receiving placebo.

Sequence of same-day upper and lower gastrointestinal endoscopy does not affect total procedure' time or medication use: A randomized trial.

BACKGROUND AND AIM: Same-day double upper and lower gastrointestinal endoscopy is frequently performed due to overlapping indications. However, it is unclear whether an upper-lower (U-L) or lower-upper (L-U) sequence is optimal. We analyzed the effect of sequence on total procedure time and sedation use. METHODS: A total of 100 patients scheduled for same-day double endoscopy were randomized to the U-L or L-U sequence arm. Primary outcomes, mean total procedure time, and sedative dosages were compared using a t-test. We also explored associations of the primary outcomes with patient-related and procedure-related factors. RESULTS: Comparing U-L and L-U sequences, mean total procedure time was 41.9 (16.2) versus 43.0 (14.5) min (P = 0.73), diphenhydramine dose 5.5 (15.4) versus 4.5 (14.0) mg (P = 0.74), fentanyl dose 71.5 (119.3) versus 77.6 (164.02) µg (P = 0.83), midazolam dose 1.6 (2.5) versus 1.4 (2.7) mg (P = 0.69), and propofol dose 437.4 (351.4) versus 444.5 (256.0) mg (P = 0.91), respectively. Total procedure and upper endoscopy times were significantly longer with trainee presence (P = 0.0002) and shorter with conscious sedation (P = 0.003). Upper endoscopy time was longer with higher body mass index (P = 0.001), and lower endoscopy time was longer in patients with cirrhosis or chronic kidney disease (P = 0.002 and 0.009, respectively). Time between procedures was significantly longer in the L-U sequence (7.4 [2.9] vs 5.3 [1.1] min, [P < 0.001]). The study had 80% power to detect an 8 min difference in total procedure time. CONCLUSIONS: The sequence of same-day double gastrointestinal endoscopy does not affect total procedure time or medication use. Longer total procedure and upper endoscopy times were associated with trainee presence and use of conscious sedation.
