Evaluation of Postural Parathyroid Hormone Change in Patients with Primary Hyperparathyroidism

Purpose. In the present study, we aimed to investigate postural change of PTH in normal individuals and in patients with primary hyperparathyroidism (PHPT). Methods. Twenty-two patients with PHPT and nine healthy controls were enrolled. Following 12 h of fast, patients stayed in recumbent position for an hour and PTH and total Ca measurements were performed at the 45th and 60th minutes of resting. Afterwards, the patients resumed an upright posture for an hour and again blood samples were taken at the 45th and 60th minutes of standing. Results. In the PHPT group, mean PTH was calculated as 153.9 pg/mL in the recumbent position while it was 206.3 during upright position (Δ change was 47.7) (P<0.001). In the control group mean serum PTH was measured as 41.2 pg/mL in the recumbent position while it was 44.8 pg/mL in the upright position (Δ change was 1.7) (P=0.11). In both groups, serum Ca was higher in the upright position compared to the recumbent position (P<0.001). Conclusion. Postural change of serum PTH is significant only in PHPT group. Postural PTH test may give a clue to the clinician when the diagnosis of PHPT is equivocal

Venture Capitalists in Firm Governance: Impact on Founder Turnover

Prior literature tells us VCs are responsible for ousting founders from their leadership positions and replacing them with professional management around IPO time. This argument assumes all founders are equally incapable of running a company beyond the initial startup phase. We question that assumption and propose that the relationship between VC involvement and founder-CEO turnover around IPO time is moderated by other variables such as the pre-IPO performance of the firm, the nature of the involvement of the VCs, and the prior experience of the founder-CEOs. Our hypotheses are tested on 108 founder-CEOs of IPO firms and supported to a large extent. Implications are discussed
