Summary

PTH promotes bone resorption, decreases urinary calcium excretion, enhances the conversion of 25-hydroxyvitamin D to 1, 25-dihydroxyvitamin D and increases intestinal calcium absorption and phosphate renal excretion. Understanding the molecular cause of the disease in patients and their families has the potential for proper tailoring of genetic counselling, family screening and treatment. Signs and symptoms may be associated not only with the severity, chronicity and therapeutic

endpoints in HPT but also with the different causes of the disease. Hypocalcaemia may be an asymptomatic laboratory finding or a life-threatening metabolic disturbance. Although the therapy of acute hypocalcaemia is usually readily accomplished, chronic hypocalcaemia remains a very difficult this website treatment problem. Replacement therapy with PTH could be a Cyclopamine research buy therapeutic option for refractory HPT.”
“OBJECTIVE: To evaluate the association of a new institutional policy limiting elective delivery before 39 weeks of gestation with neonatal outcomes at a large community-based academic center.

METHODS: A retrospective cohort study was conducted to estimate the effect of the policy on neonatal outcomes using a before and after design. All term singleton deliveries 2 years before and 2 years after policy enforcement were included. Clinical

data from the electronic hospital obstetric records were used to identify outcomes and relevant covariates. Multivariable logistic regression was used to account

for independent effects of changes in characteristics and comorbidities of the women in the cohorts before and after implementation.

RESULTS: We identified 12,015 singleton live births before and 12,013 buy Citarinostat after policy implementation. The overall percentage of deliveries occurring before 39 weeks of gestation fell from 33.1% to 26.4% (P <.001); the greatest difference was for women undergoing repeat cesarean delivery or induction of labor. Admission to the neonatal intensive care unit (NICU) also decreased significantly; before the intervention, there were 1,116 admissions (9.29% of term live births), whereas after, there were 1,027 (8.55% of term live births) and this difference was significant (P=.044). However, an 11% increased odds of birth weight greater than 4,000 g (adjusted odds ratio 1.11; 95% confidence interval [CI] 1.01-1.22) and an increase in stillbirths at 37 and 38 weeks, from 2.5 to 9.1 per 10,000 term pregnancies (relative risk 3.67, 95% CI 1.02-13.15, P=.032), were detected.

CONCLUSION: A policy limiting elective delivery before 39 weeks of gestation was followed by changes in the timing of term deliveries. This was associated with a small reduction in NICU admissions; however, macrosomia and stillbirth increased. (Obstet Gynecol 2011;118:1047-55) DOI: 10.1097/AOG.
