The Intersection of Disability and Pregnancy: Risks for Maternal Morbidity and Mortality.

It is estimated that 1 in 4 women in the United States live with a disability, and using population-based estimates, 10-12% of women of childbearing age have a disability. There are limited data to suggest that women with disabilities experience higher rates of or risks for adverse outcomes related to pregnancy, delivery, and access to appropriate postpartum care. Research on specific disabling conditions demonstrates variable risk for syndromes that threaten the health of the mother, such as preeclampsia, infection, and coagulation disorders. Much of the literature suggests that normal, healthy pregnancy is possible but points to the need for tailored information for patients and providers about the intersection of their condition with pregnancy and specific care needs. Given the lack of systematic evidence in this area across conditions and functional impairments, more research is needed to clarify the interaction of specific disabilities with pregnancy and provide evidence-based information to the field to decrease the risks to mothers and their infants. This article will provide an overview of conditions that contribute to maternal morbidity and mortality as they relate to pregnancy in women with disabilities and provide resources to the field to further the investigation of this area.

A comparison of the incidence of hypercapnea in non-obese and morbidly obese peri-operative patients using the SenTec transcutaneous pCO(2) monitor.

Obese patients are at increased risk for hypoventilation, leading to hypercapnea and acidosis. The primary objective of this study was to compare the incidence of perioperative hypercapnea in non-obese and morbidly obese patients using the SenTec transcutaneous PCO2 (tcPCO2) monitor. 10 morbidly obese subjects (BMI > 40 kg/m(2)) undergoing laparoscopic bariatric surgery, and 10 non-obese subjects (BMI < 30 kg/m(2)) undergoing laparoscopic abdominal procedures were studied, using a standardized anesthesia regimen. TcPCO2 and SpO2 were monitored continuously intraoperatively, and during the first 24 h postoperatively. Opiate consumption, respiratory rate (RR), and pain scores were collected from postanesthesia care unit (PACU) and ward nursing notes. RR, SpO2, and tcPCO2 did not differ significantly between groups during PACU or ward time periods. End-tidal CO2 (EtCO2) values were similar between groups during the intraoperative period, but tcPCO2 was significantly higher in the obese group at specific time points, and trended towards being higher throughout the case. Our study did not show significant tcPCO2 differences between non-obese and obese post-surgical patients, however, it did allow for continuous, trendable, nonobtrusive monitoring throughout the perioperative period. As V/Q mismatch increases with the PaCO2/EtCO2 gradient, and this effect is most pronounced in morbidly obese patients, tcPCO2 monitoring may prove to be a useful additional monitor in these patients during the intraoperative period.

Attitudes, experience, and anticipation of sex among 5th graders in an urban setting: does gender matter?

To identify gender differences in correlates of anticipation and initiation of sexual activity in the baseline survey of 562 African-American 5th grade students prior to initiation of a school-based pregnancy prevention intervention curriculum. Students from 16 elementary schools were administered the baseline questionnaire during classroom periods. Using these data, binary and ordered logistic regression models were used to analyze the factors affecting virginity and anticipation of sexual activity separately by gender, and tests of interaction between each factor and gender were conducted on the combined sample. More boys than girls had already had sex (18% vs. 5%) and anticipated having sexual intercourse in the next 12 months (56% vs. 22%). Boys and girls also differed in the factors that affected these outcomes. The perception that their neighborhood was safe reduced the odds that boys anticipated sexual activity but was not associated with this outcome among girls. Pubertal knowledge increased the odds of anticipation, but only among boys. Attitudes favoring abstinence decreased anticipation of sex among both genders, but slightly more among girls than boys. Having more frequent parent-child communication about sex was associated with increased anticipation among girls but decreased anticipation among boys. Curriculum based approaches to adolescent pregnancy prevention are appropriate for 5th grade elementary students who may already be anticipating sexual activity in communities with disproportionate rates of teen pregnancy. The design of the interventions should consider the differences in motivating factors by gender.

Evaluation of a randomized intervention to delay sexual initiation among fifth-graders followed through the sixth grade.

US adolescents initiate sex at increasingly younger ages, yet few pregnancy prevention interventions for children as young as 10-12 years old have been evaluated. Sixteen Washington, DC schools were randomly assigned to intervention versus control conditions. Beginning in 2001/02 with fifth-grade students and continuing during the sixth grade, students completed pre-intervention and post-intervention surveys each school year. Each year, the intervention included 10-13 classroom sessions related to delaying sexual initiation. Linear hierarchical models compared outcome changes between intervention and control groups by gender over time. Results show the intervention significantly decreased a rise over time in the anticipation of having sex in the next 12 months among intervention boys versus control boys, but it had no other outcome effects. Among girls, the intervention had no significant outcome effects. One exception is that for both genders, compared with control students, intervention students increased their pubertal knowledge. In conclusion, a school-based curriculum to delay sexual involvement among fifth-grade and sixth-grade high-risk youths had limited impact. Additional research is necessary to outline effective interventions, and more intensive, comprehensive interventions may be required to counteract adverse circumstances in students' lives and pervasive influences toward early sex.ClinicalTrials. gov identifier: NCT00341471.

Efficacy of a randomized cell phone-based counseling intervention in postponing subsequent pregnancy among teen mothers.

Adolescent mothers in Washington, DC have a high rate of subsequent teen pregnancies, often within 24 months. Children of teen mothers are at risk for adverse psychosocial outcomes. When adolescents are strongly attached to parents, schools, and positive peers, they may be less likely to repeat a pregnancy. This study tested the efficacy of a counseling intervention delivered by cell phone and focused on postponing subsequent teen pregnancies by strengthening healthy relationships, reproductive practices, and positive youth assets. The objective of this study was to compare time to a repeat pregnancy between the intervention and usual care groups, and, secondarily, to determine whether treatment intensity influenced time to subsequent conception. Primiparous pregnant teens ages 15-19, were recruited in Washington, DC. Of 849 teens screened, 29.3% (n = 249) met inclusion criteria, consented to participate, and completed baseline measures. They were then randomized to the intervention (N = 124) or to usual care (N = 125). Intervention group teens received cell phones for 18 months of counseling sessions, and quarterly group sessions. Follow-up measures assessed subsequent pregnancy through 24 months post-delivery. A survival analysis compared time to subsequent conception in the two treatment groups. Additional models examined the effect of treatment intensity. By 24 months, 31% of the intervention and 36% of usual care group teens had a subsequent pregnancy. Group differences were not statistically significant in intent-to-treat analysis. Because there was variability in the degree of exposure of teens to the curriculum, a survival analysis accounting for treatment intensity was performed and a significant interaction with age was detected. Participants who were aged 15-17 years at delivery showed a significant reduction in subsequent pregnancy with increased levels of intervention exposure (P < 0.01), but not those ≥ 18 years. Adolescents ≥ 18 years faced considerable challenges to treatment success. Individual, social, and contextual factors are all important to consider in the prevention of repeat teen pregnancy. Cell phone-based approaches to counseling may not be the most ideal for addressing complex, socially-mediated behaviors such as this, except for selective subgroups. A lack of resources within the community for older teens may interfere with program success.

Test-retest reliability and minimal detectable change of the hexagon agility test.

The purpose of this study was to examine the test-retest reliability and minimal detectable change (MDC95) of the hexagon test. The hexagon test is a routinely used measure of agility in the sports and rehabilitation professions, yet its reliability has not been investigated in prior research. A total of 26 college-aged men (n = 17) and women (n = 9) of various activity levels were recruited to participate in 3 testing sessions: baseline, 1 hour after baseline, and 48 hours after baseline. The results of this study indicated excellent test-retest reliability for both same-day intraclass correlation coefficient (ICC) model 3,1 = 0.938 and between-day ICC (3,1) = 0.924 analyses. The MDC95 for the hexagon test was 1.015 seconds. A significant difference in the mean times was identified during the same-day test-retest sessions (p < 0.001) but not the between-day test-retest sessions (p = 0.18). The significant differences identified between the baseline and the same-day retest session suggests a learning effect. The hexagon test shows excellent reliability for measuring agility, which supports its use as a tool to assess athletic performance and lower-extremity agility. Evidence of reliability, in addition to its ease of administration, makes the hexagon test a practical and effective method to measure agility. When using this test as a measure of agility, a change of greater than 1.015 seconds is necessary to be 95% certain that the change in time reflects improvement and exceeds measurement error. A practice trial is recommended prior to recording scores to attenuate the possibility of a learning effect.
