Elevated serum progesterone on the day of HCG administration in IVF is associated with a higher pregnancy rate in polycystic ovary syndrome
No full textOur study compared 84 patients with polycystic ovary syndrome (PCOS) with 84 control patients who had normal ovaries and who were matched for the main determinants of success in in-vitro fertilization (IVF) and embryo transfer. Serum concentrations of oestradiol and progesterone on the day of human chorionic gonadotrophin (HCG) injection were significantly higher in PCOS than in normal patients (oestradiol 2016 +/- 1.8 pg/ml versus 1456 +/- 40.9 pg/ml, P or = 1.2 ng/ml showed a higher pregnancy and miscarriage rate than PCOS patients with progesterone < 1.2 ng/ml (26.6 versus 17.9%, P < 0.01; and 41.7% versus 14.3%, P < 0.01 respectively). These findings suggest that premature progesterone production does not have an adverse effect on pregnancy rate in PCOS, but on the contrary, may be a predictor for success in IVF/embryo transfer

Impaired autonomic vascular control : a non linear dynamic analysis
No full textThe specific role of autonomic vascular control in determining non-linear behaviour of RR intervals is not clear. In 10 T12-L4 paraplegic subjects (light vascular autonomic impairment), 12 T 5-T11 paraplegic subjects (moderate vascular autonomic impairment), and 24 controls RR time series were recorded (10 min): 1) in resting supine position; 2) sitting on the wheelchair and 3) during a light (5W) arm exercise. Fractal Dimension (FD), Approximate Entropy (ApEn) and the a scaling exponent (α-DFA, Detrended Fluctuation Analysis) were calculated. The lesional level significantly affected ApEn (p=0.004), FD (p=0.007) and α-DFA (p=0.002). Autonomic activation did not influence FD and α-DFA, but significantly affected ApEn (p=0.03S). It seems that FD and α-DFA are influenced by the changes in nonlinear RR dynamics due to vascular autonomic impairment but not to autonomic activation, whereas ApEn may be equally responsive to either condition
Paraplegic adaptation to assisted-walking : Energy expenditure during wheelchair versus orthosis use
No full textStudy Design: To study the energy cost of locomotion during ambulation with different orthoses (HIP Guidance Orthosis Orlau Parawalker (PW), n = 4; Reciprocating Gait Orthosis (RGO), n = 6; RGO + FNS, n = 4). Objectives: Since high energy costs of locomotion have been proposed as a major reason for early rejection of orthotic use, our aims were (a) to evaluate the impact of functional neuromuscular stimulation (FNS) on energy expenditure during orthosis-assisted ambulation; (b) to study whether energy expenditure data can predict the poor long-term patients' compliance and (c) to assess selection criteria for the assignment of the different types of orthosis. Setting: The study was completed at the Center of Sports Medicine and Center of Bioengineering, 'don C. Gnocchi' Foundation, IRCCS, Milan, Italy. Methods: The HR/V̇O2 relationship and the energy cost of locomotion (C) were studied in 14 patients (lesion level C7-T11) during wheelchair (WHCH) use at various speeds and during locomotion with different orthotic devices. Patients' short- and long-term compliance were assessed by questionnaires evaluating duration of and problems related to orthotic use. Results: (a) In patients using RGO + FNS the slope difference of HR/V̇O2 curves (Δ(s1)HR/ V̇O2) between WHCH and orthosis was significantly lower than in other groups (-3 beats 1-1 in RGO + FNS vs 43 and 52 beats 1-1 in RGO and PW, respectively); (b) neither C, nor VO2 peak, or Δ(s1)HR/V̇O2 correlated with orthosis duration of use; (c) in the RGO + FNS group, C was lower at maximal walking speed, which linearly correlated with maximal WHCH speed. Conclusion: (a) Electrical stimulation seems to improve locomotion, as a consequence of hemodynamic effects, but does not decrease energy expenditure, which remains high; (b) the poor long-term compliance to orthosis use cannot be predicted by the energy expenditure parameters; (c) the subjects who can reach high speeds by WHCH seem to be the most appropriate for RGO + FNS locomotion
