According to the IMPACT study design, men underwent annual PSA screening and those with a PSA >3.0 ng ml−l were referred for a 10- or 12-core transrectal ultrasound guided (TRUS) biopsy based on institutional clinic practices.
Changes in parameters (HR, CVP, VTI, SV, and CO) were measured after the 50-ml infusion over 15 seconds and after the full 500 ml over 15 minutes; these were referred to as ∆[parameter]50 and ∆[parameter]500, respectively.
All participants with serum 25(OH D levels below 30 ng/ml were referred to a primary care physician with recommendations to take VitD supplements.
Although all controls with serum PSA >4 ng/ml were referred for additional follow-up with Urology, we were not able to ascertain what proportion of these controls had underlying PrCa.
When T4 was ≤ −3.0 SD or TSH was ≥50 μU/ml children were referred immediately.
However, 18% of controls had serum PSA values between 4.0 and 9.9 ng/ml, and 8% had PSA values between 10 and 50 ng/ml, and they were referred for facilitated follow-up in urology.> -wrap-foot> *For cases serum PSA indicates the diagnostic PSA, which was abstracted from medical records.
Of them, 798 were diagnosed with hyperthyroidism in the presence of free triiodothyronine (T3) level >1.59 ng/mL and concomitant suppressed thyroid stimulating hormone (TSH) level <0.35 mUI/mL; [ 6] 170 of them were referred to the cardiologist with cardiac symptoms, of these, 127 patients were identified with dilated cardiomyopathy and recruited for a 6 months follow-up.
Of the 2481 men, 199 (8.0%) had PSA >3.0 ng/ml (range: 3.0 27.0; median: 4.3) and were referred to a urologist to discuss prostate biopsy (Fig. 2).
Children with a dubious result (−3.0 < T4 ≤ −2.1 SD, or 25 ≤ TSH < 50 μU/ml) underwent a second heelpuncture and <span class="lh">were referred if the result was again dubious, or abnormal.
A progesterone concentration of ≥1.0 ng/ml of skim milk was referred to as a progesterone rise, due to a functional corpus luteum [ 9, 16- 19].
