Traveling for rights: Abortion trends in New Mexico after passage of restrictive Texas legislation

OBJECTIVES

To determine the proportion of abortions provided to patients from Texas in New Mexico before and after the 2013 enactment of Texas House Bill 2 (HB2), an omnibus bill of abortion restrictions, and to compare the gestational ages at which Texans presented for abortion in New Mexico before and after HB2.

STUDY DESIGN

We conducted a chart review of Texas and New Mexico patients obtaining an abortion in New Mexico abortion clinics before HB 2 was signed and implemented (time period 1: January 1, 2012 to December 31, 2012) and after HB 2 went into effect (time period 2: May 1, 2014 to April 30, 2015). We used random sampling of corresponding 7-day periods (by week number during the one-year sample) to obtain data until we reached the desired sample of at least 300 patients. We compared proportions of individuals from Texas obtaining abortions and the gestational age at which they presented in the two time periods.

RESULTS

We abstracted data from 350 and 300 Texas and New Mexico patients, respectively. The proportion of procedures provided to women from Texas increased from 10 (3%) pre-HB2 to 43 (14%) post-HB2 (p < 0.0001). The proportion of procedures in Texas patients at 13 to ≤24 weeks increased from 1 of 29 (3%) pre-HB2 to 10 of 38 (26%) post-HB2 (p = 0.012).

CONCLUSION

The proportion of Texans scheduling abortions in New Mexico within the first 24 weeks of gestation increased after passage of HB2. Restrictive legislation may force more people to travel across state lines to obtain abortion care.

IMPLICATIONS

Patients residing in Texas and seeking abortion care in Texas experienced barriers to abortion care, likely related to restrictions imposed by HB2.

The brain-derived neurotrophic factor VAL68MET polymorphism modulates how developmental ethanol exposure impacts the hippocampus

Prenatal exposure to alcohol causes a wide range of deficits known as fetal alcohol spectrum disorders (FASDs). Many factors determine vulnerability to developmental alcohol exposure including timing and pattern of exposure, nutrition and genetics. Here, we characterized how a prevalent single nucleotide polymorphism in the human brain-derived neurotrophic factor (BDNF) gene (val66met) modulates FASDs severity. This polymorphism disrupts BDNF's intracellular trafficking and activity-dependent secretion, and has been linked to increased incidence of neuropsychiatric disorders such as depression and anxiety. We hypothesized that developmental ethanol (EtOH) exposure more severely affects mice carrying this polymorphism. We used transgenic mice homozygous for either valine (BDNF^val/val ) or methionine (BDNF^met/met ) in residue 68, equivalent to residue 66 in humans. To model EtOH exposure during the second and third trimesters of human pregnancy, we exposed mice to EtOH in vapor chambers during gestational days 12 to 19 and postnatal days 2 to 9. We found that EtOH exposure reduces cell layer volume in the dentate gyrus and the CA1 hippocampal regions of BDNF^met/met but not BDNF^val/val mice during the juvenile period (postnatal day 15). During adulthood, EtOH exposure reduced anxiety-like behavior and disrupted trace fear conditioning in BDNF^met/met mice, with most effects observed in males. EtOH exposure reduced adult neurogenesis only in the ventral hippocampus of BDNF^val/val male mice. These studies show that the BDNF val66met polymorphism modulates, in a complex manner, the effects of developmental EtOH exposure, and identify a novel genetic risk factor that may regulate FASDs severity in humans.

Phase I trial of the combination of daily estramustine phosphate and intermittent docetaxel in patients with metastatic hormone refractory prostate carcinoma

BACKGROUND

To apply our preclinical findings of cytotoxic synergy with the combination of estramustine phosphate (EP) and docetaxel as the basis of treatment of hormone refractory metastatic prostate cancer in man. To determine the optimal dosage and the toxicities of these two agents for future trials.

PATIENTS AND METHODS

Seventeen patients with hormone refractory metastatic prostate cancer who were ambulatory with performance status < or = 2, normal marrow, renal and hepatic function were entered. Prior exposure to EP or a taxane were exclusion factors. EP was given orally at a dose of 14 mg/kg of body weight daily with concurrent docetaxel administered every 21 days as an intravenous infusion over 1 hour with dexamethasone 8 mg. PO BID for five days. EP dosages were kept static; docetaxel dosages were explored in a minimum of three patients per level for dosages of 40, 60, 70, and 80 mg/m2. Patients were evaluated weekly. Prostate specific antigen (PSA) was measured every three weeks.

RESULTS

Five patients were entered at a docetaxel dose of 40 mg/m2, three at 60 mg/m2, six at 70 mg/m2, and three at 80 mg/m2. Only one patient had received prior chemotherapy. Grades 1 or 2 hypocalcemia and hypophosphatemia were seen at all dosage levels. Other grade 2 or less toxicities not related to dosage included alopecia, anorexia, stomatitis, diarrhea, and epigastric pain. Dose limiting toxicities (DLT) as grade 4 leukopenia and grade 4 fatigue were seen at 80 mg/m2. The phase II dose was defined at 70 mg/m2 with rapidly reversible leukopenia and minor liver function abnormalities. At this dosing level, dose intensity was 88% and 86% over consecutive cycles for docetaxel and EP, respectively. Two vascular events occurred at this dose level (70 mg/m2): one arterial and the other venous. PSA decreases greater than 50% from baseline were seen in 14 of 17 patients at all dosage levels. Four of the 17 patients demonstrated a complete biochemical response (PSA < or = 4 ng/ml). One patient had a partial response with measurable lung and liver lesions.

CONCLUSION

EP given continuously with every three-week docetaxel at a dose of 70 mg/m2 is tolerable with evidence of antitumor activity based upon significant declines in PSA in the majority of patients and improvement of lung metastasis in one patient. Larger phase II studies of this combination in a homogenous population are warranted.
