Abstract
BACKGROUND AND OBJECTIVES We measured within-hospital concordance of mothers with opioid use disorder (OUD) and newborns with neonatal abstinence syndrome (NAS) or opioid exposure (OE). Secondarily, we described the demographics of mothers and newborns with and without opioid-related diagnoses. METHODS We used hospital discharge abstracts from California, Florida, New Jersey, and Pennsylvania in 2016. Descriptive statistics were used to compare newborns and mothers with and without opioid-related diagnoses. Within-hospital frequencies of mothers with OUD and newborns with NAS and OE were compared. Pearson's correlation coefficients were calculated. RESULTS In 474 hospitals, we found 896 702 mothers (0.6% with OUD) and 910 867 newborns (0.47% with NAS, 0.85% with OE, and 0.07% with both). Although the frequency of mothers and newborns with opioid-related diagnoses in a hospital was strongly correlated (r = 0.81), more infants were identified than mothers in most hospitals (68.3%). Mothers with OUD were more likely to be white (79% vs 40.9%), on Medicaid (75.4% vs 44.0%), and receive care in rural hospitals (20.6% vs 17.6%), compared with mothers without OUD. Newborns with NAS had demographics similar to women with OUD. Newborns with OE were disproportionately Black (22% vs 7%) or Hispanic (22% vs 9%). CONCLUSIONS More newborns are diagnosed with opioid-related disorders than mothers are. Although infants diagnosed with NAS had demographics similar to mothers with OUD, infants with OE were more likely to be Black or Hispanic. The lack of diagnostic coding of maternal OUD and the racial differences in diagnoses warrant attention.

Abstract
OBJECTIVES To determine the extent to which newborns with neonatal abstinence syndrome (NAS) are concentrated in some hospitals as compared with newborns without NAS and whether care quality and safety differed among these hospitals. We hypothesized that newborns with NAS would be cared for in poorer-quality hospitals. METHODS Secondary analysis of 3 2016 data sets: (1) the panel study of effects of changes in nursing on patient outcomes-US survey of hospital registered nurses regarding work conditions and safety, (2) inpatient discharge abstracts, and (3) the American Hospital Association annual survey. Newborns in 266 hospitals from the 4 states where the panel study of effects of changes in nursing on patient outcomes was conducted were included. We used Lorenz curves to determine if newborns with NAS were concentrated in different hospitals than newborns without NAS and whether care quality and safety differed among those hospitals. Quality and safety were assessed by staff nurses by using standard survey questions. RESULTS Of the 659 403 newborns in this study, 3130 were diagnosed with noniatrogenic NAS. We found that newborns with NAS were cared for in different hospitals compared with newborns without NAS (Gini coefficient 0.62, 95% confidence interval, 0.56-0.68) and that the hospitals in which they received care were rated as having poorer quality and safety (Gini coefficient 0.12, 95% confidence interval, 0.01-0.23). CONCLUSIONS Newborns with NAS are cared for in poorer-quality hospitals than other newborns. Our findings are of concern because poorer-quality care is linked to patient outcomes. As stakeholders seek to address the opioid epidemic and improve outcomes of newborns with NAS, our findings suggest the importance of examining hospital factors.

Trends in anticholinergic and opioid dispensing in older adults from 2004 to 2015: Results from the Personality and Total Health (PATH) Through Life Study. Australas J Ageing 2021; 40:e173-e177. [PMID: 33586319 DOI: 10.1111/ajag.12915] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/05/2020] [Revised: 11/09/2020] [Accepted: 12/17/2020] [Indexed: 11/27/2022]
Abstract
OBJECTIVE Due to potential adverse effects, guidelines recommend that anticholinergics and opioids be avoided in older adults unless necessary. This study examines the dispensing trends of these medications among older Australians. METHODS Data of 2222 PATH study (60+ cohort) participants were analysed. Medication dispensing data were obtained from the Pharmaceutical Benefits Scheme from April 2004 to March 2015. Temporal trends of prescriptions dispensed were assessed using joinpoint regression analysis. RESULTS Of all dispensed prescriptions, 5.5% were for anticholinergics and opioids, and 46.2% of anticholinergics dispensed were anti-depressants. Anticholinergic dispensing trend increased in 2004-2015 (annual per cent change, APC = 3.4%), particularly for moderately anticholinergic medications (APC = 6.8%). Dispensing trend for opioids increased in 2004-2011 (APC = 11.3%) and declined in 2011-2015 (APC = -4.4%). CONCLUSION While guidelines urge caution in prescribing these medications to older adults, dispensing increased over time in this study population.

Abstract
PURPOSE This study examined the association between sleep duration trajectories from adolescence to young adulthood and the risk of asthma into young adulthood. METHODS Using data from 10,362 participants in the National Longitudinal Study of Adolescent to Adult Health (Add Health) free of asthma at baseline, we constructed trajectories of sleep duration from adolescence (age 13-18 years) to young adulthood (age 24-32 years) and used them to examine the association between sleep duration patterns and the risk of new-onset asthma using a log-binomial regression model after adjusting for potential confounders. RESULTS The results revealed that 14.4% of nonasthmatic participants had persistent short sleep duration, whereas 80.0% had adequate sleep duration from adolescence through young adulthood. Consistently short-sleepers had 1.52 times the risk of new-onset asthma by age 32 years (95% CI 1.11, 2.10) compared with consistently adequate sleepers. The association was stronger in those with a family history of asthma (aRR = 2.43, 95% CI 1.15, 5.13) than in those without such history (aRR = 1.43, 95% CI 1.05, 1.95). CONCLUSIONS We conclude that persistent short sleep duration is associated with an increased risk of new-onset asthma in young adults. This association may be more pronounced among those at high risk of asthma because of family history.

Abstract
INTRODUCTION Today women comprise 15% of the U.S. active-duty military, but are often overlooked in research of the Armed Forces. While some of the challenges faced by women are similar to men, they encounter unique stressors, including pregnancy-related issues. Hypertensive disorders of pregnancy (HDPs) affect 5-10% of pregnancies annually and have been linked to maternal stress, but no studies have assessed the impact of maternal military deployment on HDP incidence. Thus, the purpose of the current study was to quantify the risk of HDP among active-duty U.S. military mothers who deployed in the post-9/11/2001 era. MATERIALS AND METHODS We conducted a retrospective cohort study using a U.S. Department of Defense database comprised of all active-duty women who gave birth to their first, live-born singleton infant using Tricare from January 1, 2004 to December 31, 2008. The database included records for maternal/infant birth hospitalizations and deployment. HDP was defined with ICD-9-CM codes in the maternal birth hospitalization record. We evaluated the risk of HDP associated with several deployment measures for the cohort overall and among racial/ethnic groups: (1) deployment in general (yes vs. no); (2) timing of deployment ending prior to birth (<12 months or ≥12 months prior vs. non-deployed); and, (3) cumulative time spent deployed since 9/11/2001. We used multivariable logistic regression and reported odds-ratios (OR) and 95% confidence intervals (CI). We also explored meaningful categorization of certain continuous deployment measures associated with HDP incidence. The study was approved by the University of South Florida Institutional Review Board. RESULTS There were a total of 36,667 births and 13.4% of mothers experienced at least one HDP. No increased risk of HDP was observed for deployed mothers compared with non-deployed mothers in the complete cohort (OR = 1.02, 95% CI: 0.95-1.09), but cumulative deployment length ≥1 year was identified as a potential risk factor for HDP vs. <1 year deployment (OR = 1.17, 95% CI: 1.00-1.36). CONCLUSION Our study was the first to quantify the incidence of HDP among active-duty military women giving birth to their first child. It was slightly higher than in the general population, but deployment overall is seemingly not responsible for the elevated incidence.

Linking the work environment to missed nursing care in labour and delivery. J Nurs Manag 2019; 28:1901-1908. [PMID: 31449691 DOI: 10.1111/jonm.12856] [Citation(s) in RCA: 31] [Impact Index Per Article: 6.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/11/2019] [Revised: 08/14/2019] [Accepted: 08/23/2019] [Indexed: 12/01/2022]
Abstract
AIM To measure the association between the nurse work environment (NWE) and missed nursing care on labour and delivery (L&D) units. BACKGROUND L&D units provide a sizable fraction of acute hospital services to a unique population that is a national and global priority. L&D nurses are the frontline providers during labour. Maternal morbidity and mortality may be influenced by the NWE and missed care. METHODS This cross-sectional study utilized secondary data from 1,313 L&D staff nurses in 247 hospitals from a four-state nurse survey collected in 2005-2008. RESULTS Half of nurses missed care (range: zero to 100% across hospitals). Nurses on average missed 1.25 of 10 activities. The most commonly missed activities were comforting/talking with patients and teaching/counselling. In better as compared to poor NWEs, the odds and frequency of missed care were significantly lower. CONCLUSIONS L&D nurses routinely miss necessary nursing activities. Labouring women's psychosocial, comfort and educational needs are compromised most often, likely impacting quality and outcomes. Nurse communication with colleagues and managers about missed care is warranted. IMPLICATIONS FOR NURSING MANAGEMENT The L&D NWE is modifiable and appears to influence missed care. Managers should discuss missed care with staff and measure their NWE to identify actionable weaknesses.

Abstract
OBJECTIVE To examine the relationship between depression and/or anxiety and any psychiatric diagnosis and readmission after childbirth. DESIGN Cross-sectional analysis of administrative data from patient discharge records. SETTING Urban academic medical center in the northeastern United States. PARTICIPANTS Women admitted for childbirth (N = 17,905). METHODS Differences among participants with and without depression and/or anxiety present on admission were compared using t tests and chi-square tests. Risk-adjusted logistic regression models were used to examine the effects of depression and/or anxiety and any psychiatric diagnosis on 7-, 30-, 60-, 90-, and 180-day readmissions after childbirth. RESULTS Significant differences were noted between participants with (n = 1,169) and without (n = 16,736) depression and/or anxiety. Participants with these diagnoses had a higher mean age and a longer mean length of stay during hospitalization for childbirth. A greater proportion of these participants were White, were single, had cesarean births, and were discharged with home health services. The presence of depression and/or anxiety was not significantly associated with readmission. The effect of having any psychiatric diagnosis was significantly associated with a greater risk of readmission at 7 (odds ratio [OR] = 1.51, p = .100), 30 (OR = 1.45, p = .030), 60 (OR = 1.45, p = .026), 90 (OR = 1.56, p = .004), and 180 days (OR =1.74, p < .001) following discharge after childbirth. CONCLUSION In this sample, women with a psychiatric diagnosis, but not depression and/or anxiety alone, were at increased risk for readmission after childbirth.

Abstract
BACKGROUND Women are more likely to develop post-traumatic stress disorder (PTSD) than men. Limited research exists evaluating the risk of hypertensive disorders of pregnancy (HDP) among military women with PTSD. METHODS We conducted a retrospective cohort study using US Department of Defense (DoD) data comprised of all active-duty women giving birth to their first, liveborn singleton infant using DoD-sponsored health insurance from 1 January 2004 to 31 December 2008 (n = 34 176). Birth hospitalisation records, maternal mental health visits, and Post-Deployment Health Assessment (PDHA) and Reassessment (PDHRA) screenings were included. The HDP outcome (yes vs no) was defined using ICD-9-CM codes in the maternal birth hospitalisation record. Women fit into one of four PTSD exposure categories (confirmed, probable, possible, none). Confirmed cases had a PTSD ICD-9-CM diagnosis code. Probable/possible cases were classified using PDHA screening items. We used multiple log-linear regression to assess PTSD (confirmed, any vs none) and the risk of HDP overall, and then explored effect modification by military service and demographic variables. We assessed the risk of HDP among deployed mothers with PTSD (confirmed, probable/possible vs none) who completed a PDHA, and explored effect modification by race/ethnicity. We also assessed risk of HDP with differing PTSD lead times. RESULTS Overall, PTSD was not associated with HDP except among mothers whose PTSD was diagnosed ≥1 year prior to conception (RR 1.42, 95% CI 1.06, 1.90). CONCLUSIONS Post-traumatic stress disorder preceding conception by at least a year appeared to confer an increased risk of HDP, but further research is needed using more thorough PTSD assessment.

Abstract
OBJECTIVE Obstetric hemorrhage is a leading cause of morbidity and mortality. We sought to assess whether institution of a postpartum hemorrhage (PPH) bundle could improve maternal morbidity in our population. STUDY DESIGN Preintervention data (PRE) was collected on all deliveries at Hospital of the University of Pennsylvania between October 15, 2013 and December 15, 2013. A two-pronged, multidisciplinary educational and procedural intervention related to PPH was instituted from March 2015 to June 2015. Postintervention data (POST) was collected on all deliveries from October 20, 2015 to December 20, 2015. RESULTS Note that 592 of 626 (95%) PRE and 583 of 613 (95%) POST deliveries were included. The rates of PPH by estimated blood loss (EBL) ≥ 1,000 mL and by 3 g hemoglobin drop were not significantly different from PRE to POST (9.0% versus 12.2%, p = 0.07 and 10.5% versus 13.5%, p = 0.10, respectively). There was no significant change in transfusion rate (3.4% versus 5.1%, p = 0.13). Use of uterotonics was reduced from 9.8 to 6.3% from PRE to POST (p = 0.03). CONCLUSION While institution of a PPH bundle is designed to improve the morbidity of PPH, our data demonstrate that it cannot be expected to do so within 6 months of implementation. Further studies will need to assess the long-term effects of such a resource-intensive protocol, including perceptions of improved safety by all providers, nurses, and staff.

Abstract
OBJECTIVE To identify the live-birth prevalence, trends, correlates, and neonatal and 1-year survival rates of congenital diaphragmatic hernia. METHODS Using a population-based, retrospective cohort study design, we examined 1,025 cases of congenital diaphragmatic hernia from the 1998-2012 Florida Birth Defects Registry. We used Poisson and joinpoint regression models to compute prevalence ratios and temporal trends, respectively. Kaplan-Meier survival curves and Cox proportional hazards regression were used to describe neonatal and 1-year survival and estimate hazard ratios representing the predictors of infant survival. RESULTS The birth prevalence of congenital diaphragmatic hernia was 3.19 per 10,000 live births (95% confidence interval [CI]: 3.00-3.39); there was a 4.2% yearly increase among multiple cases only. Among all cases, maternal education less than high school (prevalence ratio: 1.25, 95% CI: 1.02-1.53), high school/associate degree/GED (prevalence ratio: 1.15, 95% CI: 1.01-1.32), multiple birth (prevalence ratio: 1.38, 95% CI: 1.05-1.81), and male sex (prevalence ratio: 1.18, 95% CI: 1.05-1.32) were associated with increased risk for congenital diaphragmatic hernia. The 24-hr, neonatal, and 1-year survival rates were 93.6%, 79.8%, and 71.2%, respectively. The highest hazard ratio of 17.87 (95% CI: 1.49-213.82) was observed for neonatal mortality among cases associated with chromosomal anomalies and born <37 weeks at < 1,500 g. Among isolated cases, multiple birth (hazard ratio: 0.41, 95% CI: 0.20-0.86) was associated with decreased 1-year mortality. CONCLUSION Low maternal education and multiple birth may be linked to congenital diaphragmatic hernia. The trends in prevalence, epidemiologic correlates, and predictors of early survival can differ between congenital diaphragmatic hernia subtypes-isolated, multiple, and chromosomal.© 2018 Wiley Periodicals, Inc. © 2018 Wiley Periodicals, Inc.

Abstract
Study Objectives This study examines the effects of short and long sleep duration patterns in young adults on the levels of C-reactive protein (CRP), as well as the potential effect modification by sex. Methods Using data from waves III (age 18-26) and IV (age 24-32) of the National Longitudinal study of adolescent to adult health, we examined the association between sleep trajectories in young adults, and the risk of elevated high sensitivity-CRP (hs-CRP), a marker of systemic inflammation. Results Short sleep trajectories were associated with significantly elevated log-transformed hs-CRP (coefficient = 0.11, p-value .03) and with significantly higher odds of having hs-CRP levels > 3 mg/L (OR = 1.86, 95% CI 1.29, 2.67). The association was modified by sex, with the association between short sleep duration and hs-CRP limited to males. Both the continuous (coefficient 0.117, p-value = .0362) and the categorized hs-CRP (OR = 2.21, 95% CI 1.48, 3.30) were significantly elevated with short sleep durations in males, whereas no significant associations were seen in females with short sleep durations. By contrast, log hs-CRP was significantly elevated in females with long sleep durations (coefficient = 0.232, p-value = .0296), with a nonsignificant increase in the odds of having hs-CRP levels greater than 3 mg/L (OR = 1.48, 95% CI 0.75, 2.93), whereas there were no associations with long sleep duration in males. Conclusions Systemic inflammation, measured by an elevated level of hs-CRP, is seen with persistent short sleep duration in young adult men and persistent long sleep duration in young adult women.

Abstract
OBJECTIVE The National Partnership for Maternal Safety released a postpartum hemorrhage bundle in 2015 recommending quantification of blood loss (QBL) for all deliveries. We sought to determine whether QBL more accurately predicts hemoglobin (Hb) drop than visually estimated blood loss (EBL). STUDY DESIGN This is a prospective observational study. Preintervention data (PRE) were collected on all deliveries between October 15, 2013 and December 15, 2013. Deliveries were included if EBL, admission Hb, and 12-hour postpartum Hb (12hrCBC) were available. QBL was implemented in July 2015. Postintervention data (POST) were collected between October 20, 2015 and December 20, 2015. A total of 500 mL EBL was predicted to result in 1 g/dL Hb drop at 12hrCBC. Student's t-test was used to compare the means. RESULTS A total of 592 of 626 (95%) PRE and 583 of 613 (95%) POST deliveries were included. Overall, 278 (48%) POST deliveries had QBL recorded. In both PRE and POST, actual Hb drop differed from predicted by 0.6 g/dL in both groups of deliveries. When evaluating deliveries with EBL > 1,000 mL, QBL in POST was slightly better at predicting Hb drop versus EBL in PRE, although not statistically significant (0.2 vs. 0.5 g/dL, p = 0.17). CONCLUSION In all deliveries, QBL does not predict Hb drop more accurately than EBL. The decision to perform QBL needs to balance accuracy with a resource intense measurement process.

DESIGN Preassessment and postassessment online surveys. SETTING A 13-bed labor and delivery unit in a quaternary care, Magnet Recognition Program, academic medical center in Pennsylvania. PARTICIPANTS Preintervention (n = 100), postintervention (n = 52), and 6-month follow-up survey respondents (n = 75) represented secretaries, registered nurses, surgical technicians, certified nurse-midwives, nurse practitioners, maternal-fetal medicine fellows, anesthesiologists, and obstetric and family medicine attending and resident physicians from triage and labor and delivery units. METHODS We educated staff and implemented interventions, an admission huddle and safety time-out whiteboard, to standardize the admission process. Participants were evaluated with the use of preintervention, postintervention, and 6-month follow-up surveys about their perceptions regarding the admission process. Data tracked through the electronic medical record were used to determine compliance with the admission huddle and whiteboards. RESULTS A 77% reduction (decrease of 49%) occurred in the perception of incomplete patient admission processes from baseline to 6-month follow-up after the intervention. Postintervention and 6-month follow-up survey results indicated that 100% of respondents responded strongly agree/agree/neutral that the new admission process improved communication surrounding care for patients. Data in the electronic medical record indicated that compliance with use of admission huddles and whiteboards increased from 50% to 80% by 6 months. CONCLUSION The new patient admission process, including a huddle and safety time-out board, improved staff perception of the quality of admission from obstetric triage to the labor and delivery unit.

Bioaccumulation of metals in juvenile rainbow trout (oncorhynchus mykiss) via dietary exposure to blue mussels. CHEMOSPHERE 2017; 188:548-556. [PMID: 28915373 DOI: 10.1016/j.chemosphere.2017.08.141] [Citation(s) in RCA: 9] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 04/15/2017] [Revised: 08/18/2017] [Accepted: 08/28/2017] [Indexed: 06/07/2023]
Abstract
The potential for metals to bioaccumulate in aquatic species, such as fish, via trophic level transfer was investigated. An in vivo experiment was set up in a flow-through system in which juvenile rainbow trout were fed blue mussels collected from a Class A pristine site and an effluent-impacted river estuary, over a period of 28 days. Selected elements (As, Cd, Cr, Co, Cu, Fe, Pb, Mn, Mo, Ni, Se, Sn, V, Zn) were determined in the mussels and fish tissues (muscle and skin) collected at 0, 14 and 28 days. This study reveals the occurrence of metals in mussels sampled in the Irish marine environment and highlights the bioaccumulation potential of metals in fish tissues via trophic transfer. All 14 monitored metals were determined in the mussels collected from both sites and mussels collected from the effluent-impacted site contained three times more Co, Mo, Sn and V than the mussels collected from the Class A site. Following a 28-day dietary exposure, concentrations of As and Se (fish muscle), and Pb, Se and Zn (fish skin), were significantly greater in fish feeding on contaminated mussels compared to those with a regular fish feed diet. The significance of metal detection and bioaccumulation in the mussel and fish tissues, highlights the potential for metal exposure to humans through the food chain. As fish are recommended as a healthy and nutritious food source, it is important to fully understand metal bioaccumulation in commercially important aquatic species and ensure the safety of human consumers.

Abstract
The unprecedented scale of the 2014-2015 Ebola virus outbreak in West Africa and the recent emergence and rapid spread of Zika virus infection and resultant neonatal sequelae show that the geographic range, spread, and effect of emerging infections are unpredictable. Lessons learned from analyzing the response of an academic medical center to care for pregnant women with suspected or confirmed Ebola virus disease can help health care professionals address future threats from emerging infections.

Abstract
PURPOSE To examine the association between sleep duration and asthma among Florida high school students and whether body mass index (BMI) modifies this association. METHODS This cross-sectional analysis included 16,728 participants in the Florida Youth Risk Behavior Survey (2009-2013). Using logistic regression, we examined the association between sleep duration and asthma, and, after controlling for potential confounders, analyzed the interaction between sleep duration and BMI. RESULTS Sleeping for less than 7 h or more than 8 h on school night was associated with increased odds of current asthma. Compared with 7-8 h of sleep per night, sleeping for <7 h had an OR of 1.22 (95% CI 1.07, 1.40), while sleeping for ≥9 h had and OR of 1.31 (1.06, 1.63). When stratified by body mass index (BMI), these associations were significant only in overweight adolescents, with those sleeping for <7 or ≥9 h having approximately twice the odds of having current asthma (OR = 1.75 (1.45, 2.11) and OR = 2.00 (1.32, 3.02) respectively), compared with normal weight adolescents who slept for 7-8 h per night. CONCLUSION The association between sleep duration and asthma in adolescents is modified by BMI. Short and long sleep durations are associated with asthma in overweight adolescents while no significant association is seen in those with normal BMI.

Abstract
Vitamin supplements are an effective means of obtaining adequate folate but little is known about vitamin use during the postpartum period, a time when women may be at risk of folate deficiency and associated health risks. This cross-sectional study evaluated factors associated with supplemental vitamin use to facilitate development of educational programs. Personal interviews were conducted among 188 Hispanic women at WIC clinics in El Paso, Texas. Most women (91%) used vitamin supplements during pregnancy; however, the majority (65%) discontinued use by the first postpartum month. Hispanic women born in Mexico (versus U.S. born), multiparas, younger mothers, and women who never breast fed were significantly less likely to take supplemental vitamins. Educational programs on the importance of vitamin supplements during the postpartum period are needed to insure that women receive adequate folate. On the U.S./Mexico border, programs should be tailored to younger, Mexican-born women.

Abstract
Florida ranks third among states with the lowest children's insurance coverage, due to constraints such as language barriers, multiple programs, documentation requirements, limited outreach, and short enrollment periods. In November 2004, Florida announced a 30-day children's health insurance enrollment period for January 2005 following an 18-month closure. This article describes the development, implementation, and evaluation of a communication plan creating coalitions between community partners, government agencies, and child advocacy groups to inform families. Over 96,000 families applied, almost five times any previous monthly enrollment. This campaign serves as a template for implementing strategies and engaging community partners to reduce the number of uninsured children.

Abstract
Teen mothers are at increased risk of subsequent adolescent births. Interventions to reduce secondary teen pregnancies are expensive and difficult to evaluate. An ecological evaluation compared change in the repeat teen birth rate in an intervention community in Charleston, South Carolina over time to state birth certificate data to determine the efficacy of a school-based pregnancy prevention program. Evaluation included comparison of birth rates for multigravida teens in the program's school catchment area (intervention zip codes) to selected state and community data before, during and after program implementation. The intervention community demonstrated a decrease in repeat teen births during the intervention period of the program with a rebound after it was discontinued. This trend differed from a 50% linear decrease across these time periods in the state. This low cost evaluation method may be useful for evaluation of teen pregnancy prevention programs with limited resources for program evaluation.

Abstract
The Paced Auditory Serial Addition Test (PASAT) is the chosen task for cognitive assessment in the multiple sclerosis functional composite (MSFC) and a widely used task in neuropsychological studies of people with multiple sclerosis (MS), but is unpopular with patients. The Face-Symbol Test (FST) and Symbol-Digit Tests (SDT) are alternative methods of cognitive testing in MS, which are easily administered and patient-friendly. In order to evaluate the potential of the FST as a possible surrogate for the PASAT, we directly compared the FST to the PASAT and the SDT in a cohort of 50 MS patients with varying levels of disability. There was significant correlation between SDT and FST scores (Spearman’s rho 0.80, 95% CI 0.66 - 0.88), R2 65%, with moderate inter-test agreement (κ = 0.52). In contrast, SDT and FST scores were less predictive of PASAT scores. We concluded that neither the FST nor SDT are reliable surrogates for the PASAT.

Abstract
PURPOSE Our objective was to explore if women who experience emergency peripartum hysterectomy (EPH), a type of severe maternal morbidity, are more likely to screen positive for post-traumatic stress disorder (PTSD) compared to women who did not experience EPH. METHODS Using a retrospective cohort design, women were sampled through online communities. Participants completed online screens for PTSD. Additionally, women provided sociodemographic, obstetric, psychiatric, and psychosocial information. We conducted bivariate and logistic regression analyses, then Monte Carlo simulation and propensity score matching to calculate the risk of screening positive for PTSD after EPH. RESULTS 74 exposed women (experienced EPH) and 335 non-exposed women (did not experience EPH) completed the survey. EPH survivors were nearly two times more likely to screen positive for PTSD (aOR: 1.90; 95 % CI: 1.57, 2.30), and nearly 2.5 times more likely to screen positive for PTSD at 6 months postpartum compared to women who were not EPH survivors (aOR: 2.46; 95 % CI: 1.92, 3.16). CONCLUSION The association of EPH and PTSD was statistically significant, indicating a need for further research, and the potential need for support services for these women following childbirth.

Abstract
INTRODUCTION Our objective was to determine the incidence and mortality rates associated with emergency peripartum hysterectomy, factors that lead to uncontrolled hemorrhage and emergency peripartum hysterectomy, and to determine the relationship between cesarean section and risk of emergency peripartum hysterectomy. MATERIALS AND METHODS Studies published between January 1, 2000 and December 31, 2012 were identified using PubMed, OVID and Web of Science databases. Studies were included if they reported incidence rates for emergency peripartum hysterectomy, factors that lead to hemorrhage and emergency peripartum hysterectomy, or the association of emergency peripartum hysterectomy with cesarean section in high-income countries. RESULTS Four hundred and fifty-one studies were identified, and 52 were included. The incidence of emergency peripartum hysterectomy ranged from 0.20 to 5.09 per 1000 deliveries with a median incidence rate of 0.61 per 1000 deliveries. These rates have increased over time. Rates varied by region/country, specifically with the United States reporting higher rates than North American, Asian, Oceania, and European countries. The most common factor leading to emergency peripartum hysterectomy was placental abnormalities. Both cesarean section and prior cesarean section were strong risk factors for emergency peripartum hysterectomy with higher risks conferred for each additional cesarean section. The mean percentage of maternal deaths for EPH survivors was 3.0 %. CONCLUSION Given the association of cesarean section with emergency peripartum hysterectomy, the increased risk of emergency peripartum hysterectomy should be factored into the decision of whether to proceed with cesarean delivery, particularly for women who desire more children.

Abstract
INTRODUCTION The patient presenting with proximal muscle weakness, elevated serum creatinine kinase and myopathic electromyography and biopsy findings has a wide differential diagnosis that includes toxic, autoimmune, paraneoplastic and congenital myopathies. Autoimmune myopathies are important to identify because they may respond to immunosuppressive therapies. METHODS We describe two cases of immune-mediated necrotizing myopathy each associated with a novel antibody. RESULTS Case 1 describes a progressive myopathy in a statin user. Antibodies to 3-hydroxy-3-methyl-glutaryl-coenzyme A reductase were identified and the patient responded to steroid therapy. Case 2 describes an aggressive myopathy associated with antibodies to signal recognition particle. There was no response to steroids. Clinical improvement followed treatment with rituximab and cyclophosphamide. CONCLUSION The identification of myositis-specific antibodies is important because they are associated with distinct clinical phenotypes and may guide the physician in terms of treatment strategies.

Abstract
Background: Central nervous system (CNS) relapse in diffuse large B-cell lymphoma (DLBCL) is a devastating complication; the optimal prophylactic strategy remains unclear. Methods: We performed a multicentre, retrospective analysis of patients with DLBCL with high risk for CNS relapse as defined by two or more of: multiple extranodal sites, elevated serum LDH and B symptoms or involvement of specific high-risk anatomical sites. We compared three different strategies of CNS-directed therapy: intrathecal (IT) methotrexate (MTX) with (R)-CHOP ‘group 1' R-CHOP with IT MTX and two cycles of high-dose intravenous (IV) MTX ‘group 2' dose-intensive systemic antimetabolite-containing chemotherapy (Hyper-CVAD or CODOXM/IVAC) with IT/IV MTX ‘group 3'. Results: Overall, 217 patients were identified (49, 125 and 43 in groups 1–3, respectively). With median follow-up of 3.4 (range 0.2–18.6) years, 23 CNS relapses occurred (12, 10 and 1 in groups 1–3 respectively). The 3-year actuarial rates (95% CI) of CNS relapse were 18.4% (9.5–33.1%), 6.9% (3.5–13.4%) and 2.3% (0.4–15.4%) in groups 1–3, respectively (P=0.009). Conclusions: The addition of high-dose IV MTX and/or cytarabine was associated with lower incidence of CNS relapse compared with IT chemotherapy alone. However, these data are limited by their retrospective nature and warrant confirmation in prospective randomised studies.

Abstract
BACKGROUND Little is known of the experience and perceptions of care for survivors of emergency peripartum hysterectomy (EPH), an obstetric event that is increasing in incidence. We sought to explore women's experiences of EPH to make recommendations for care. METHODS This qualitative study utilized purposive sampling through an online support group of women who experienced EPH. Eligible participants were at least 18 years old, had their hysterectomy at least 6 months but no more than 3 years before the interview, had a surviving infant associated with the delivery, and did not report suicidal ideation. In-depth, semi-structured telephone interviews were conducted and analyzed using Constant Comparative Analysis. Kappa statistics assessed interrater reliability for two independent coders. RESULTS Fifteen women participated with a mean age of 32.5 years. Most had a cesarean section, with uterine atony as the most common indication for EPH. Kappa statistics indicated near-perfect interrater agreement between two coders, ranging from .82 to .89. Seven major themes were identified: fear; pain; death and dying; numbness or delay in emotional reaction; bonding with baby; communication; and the need for information. Psychological upset occurred postpartum and was often delayed. A major finding is the need for additional follow-up visits to address the emotional after-effects and to fill in gaps in women's understanding and memory of what had occurred. CONCLUSION Understanding women's experiences with EPH can help practitioners address not only women's initial complications but provide needed long-term support.

Abstract
BACKGROUND Non-melanoma skin cancer (NMSC), comprised of basal (BCC) and squamous (SCC) cell carcinomas, is the most common cancer in Caucasians. Ultraviolet radiation (UVR) exposure is the most important environmental risk factor for NMSC. However, the precise relationship between UVR and the risk of NMSC is complex, and the relationship may differ by skin cancer type. METHODS A case-control study was conducted among Florida residents to investigate measures of patterns (intermittent vs. continuous) and timing (childhood vs. adulthood) of sunlight exposure in BCC and SCC. Participants included 218 BCC and 169 SCC cases recruited from a university dermatology clinic and 316 controls with no history of skin or other cancers. RESULTS A history of blistering sunburn (a measure of intermittent sunlight exposure) was associated with both BCC (OR = 1.96, 95% CI = 1.27-3.03) and SCC (OR = 2.02, 95% CI = 1.22-3.33). Additionally, having a job in the sun for ≥ 3 months for 10 years or longer (a measure of continuous sunlight exposure) was also associated with both BCC and SCC in our study population. With the exception of younger age at first blistering sunburn, measures of younger age at sunlight exposure tended to be associated with SCC, but not BCC risk. CONCLUSIONS Results from the current study suggest that sunlight exposure is associated with both BCC and SCC risk regardless of the pattern in which the exposure was received (i.e. intermittent vs. continuous). The data also suggest that sunlight exposure at a younger age may be more important for SCC but not BCC, however additional studies are needed to further characterize sunlight exposure-response relationships in different types of NMSC.

Abstract
BACKGROUND Ultraviolet radiation exposure may interact synergistically with cutaneous human papillomavirus (HPV) infection in the development of basal cell carcinoma (BCC) and squamous cell carcinoma (SCC) of the skin. METHODS To investigate differences in the risk of sunlight-associated BCC and SCC by cutaneous genus-specific HPV serostatus, a case-control study was conducted among 204 BCC and 156 SCC cases who were recruited from a university dermatology clinic and 297 controls who had no history of cancer and screened negative for current skin cancer. Logistic regression was used to calculate odds ratios (ORs) and 95% confidence intervals (CIs) for the associations between measures of sunlight exposure and BCC/SCC, stratified by genus-specific HPV serostatus, with adjustment for age and sex. RESULTS Sunburn due to cutaneous sensitivity to sunlight exposure (P = .006) and poor tanning ability (P = .003) were associated with a higher seroprevalence for genus beta HPV types. Poor or no tanning ability was more strongly associated with SCC among individuals who were seropositive for antibodies to cutaneous HPV types in genera alpha (OR, 15.60; 95% CI, 5.40-45.1; P = .01 for interaction) and beta (OR, 6.86; 95% CI, 3.68-12.80; P = .001 for interaction), compared with individuals who were seronegative for these HPV types. CONCLUSIONS Seropositivity for HPV types in genera alpha or beta increased the risk of SCC associated with poor tanning ability.

The role of pharmacists and emergency contraception: Are pharmacists' perceptions of emergency contraception predictive of their dispensing practices? Contraception 2012; 86:370-5. [PMID: 22386228 DOI: 10.1016/j.contraception.2012.01.014] [Citation(s) in RCA: 20] [Impact Index Per Article: 1.7] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/11/2011] [Revised: 01/11/2012] [Accepted: 01/24/2012] [Indexed: 11/19/2022]
Abstract
BACKGROUND Pharmacists can play a critical role in the access to emergency contraception (EC). We assessed if knowledge and attitudes were predictive of EC dispensing among a statewide sample of Florida pharmacists, who have legal authority to refuse to dispense medications. STUDY DESIGN In 2008, surveys were mailed to a random sample of 1264 pharmacists registered with the Florida Board of Pharmacy. Data from 272 pharmacists (22% response rate) were analyzed using bivariate and multivariate logistic regression. RESULTS Fifty-six percent of respondents incorrectly answered that EC causes birth defects, and 46% replied that it causes abortion. Only 22% said that EC can be purchased in advance of need. Many felt uncomfortable dispensing to adolescents (61%) and men (58%). Knowledge about EC was the most important predictor of dispensing [odds ratio (OR)=1.57, 95% confidence interval (CI) 1.22-2.03]. In particular, pharmacists who reported that EC does not act as an abortifacient were more likely to dispense it (OR=4.64, 95% CI 2.15-10.00). CONCLUSIONS Correct information about EC was the most important predictor of pharmacists' dispensing EC. To expand availability of EC, pharmacists will have to become better informed.

The role of a movement disorders clinic. IRISH MEDICAL JOURNAL 2012; 105:57-59. [PMID: 22455244] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Subscribe] [Scholar Register] [Indexed: 05/31/2023]
Abstract
Ireland's ageing population will result in a substantial increase in neurodegenerative disease with a projected increase in prevalence of Idiopathic Parkinson's disease (IPD) to 9,000 by 2021. There are few published audits of neurology services to assist care planning. As a first step towards evaluating future service needs for this group of patients, we audited a single tertiary referral IPD and Other Movement Disorders clinic for 2006. A total of 497 patients from all counties in Ireland were seen; 225 (59%) of patients had IPD, 32 (8.2%) had atypical parkinsonism, and 22 (5.8%) dystonia. In a subset of 275 patients, 151 (55%) were referred by GPs, 74 (27%) by other consultants, and 49 (18%) by other consultant neurologists. Diagnosis was changed in 22 (38%) and medication was adjusted in 203 (74%). A telephone survey of 50 patients demonstrated 100% satisfaction with the improved access to the clinical nurse specialist, telephone support and improved continuity of care. The IPD and Other Movement Disorders clinic provides an important local, regional, and national diagnostic and therapeutic service for complex movement disorders. It is proposed that a national registry of IPD and audit of the delivery of care to patients with movement disorders is needed.

Effects of the pharmaceuticals gemfibrozil and diclofenac on the marine mussel (Mytilus spp.) and their comparison with standardized toxicity tests. MARINE POLLUTION BULLETIN 2011; 62:1389-1395. [PMID: 21652050 DOI: 10.1016/j.marpolbul.2011.04.043] [Citation(s) in RCA: 35] [Impact Index Per Article: 2.7] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 03/11/2011] [Revised: 04/19/2011] [Accepted: 04/26/2011] [Indexed: 05/30/2023]
Abstract
Human pharmaceuticals, like the lipid lowering agent gemfibrozil and the non-steroidal anti-inflammatory drug diclofenac are causing environmental concern. In this study, the marine mussel (Mytilus spp.) was exposed by injection to environmentally relevant and elevated (1 μg/L and 1000 μg/L) concentrations of both compounds and biomarker expression was observed. Gemfibrozil exposure induced biomarkers of stress (glutathione S-transferase and metallothionein) at both concentrations 24h and 96 h after exposure, respectively. Biomarkers of damage (lipid peroxidation (LPO) and DNA damage) were significantly affected, as well as the biomarker for reproduction, alkali-labile phosphate assay, indicating the potential oxidative stress and endocrine disrupting effect of gemfibrozil. Diclofenac significantly induced LPO after 96 h indicating tissue damage. Additionally standard toxicity tests using the marine species Vibrio fischeri, Skeletonema costatum and Tisbe battagliai showed differences in sensitivity to both drugs in the mg/L range. Results indicate a suite of tests should be used to give accurate information for regulation.

Effects of the pharmaceuticals gemfibrozil and diclofenac on biomarker expression in the zebra mussel (Dreissena polymorpha) and their comparison with standardised toxicity tests. CHEMOSPHERE 2011; 84:657-63. [PMID: 21489596 DOI: 10.1016/j.chemosphere.2011.03.033] [Citation(s) in RCA: 20] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 01/14/2011] [Revised: 03/07/2011] [Accepted: 03/19/2011] [Indexed: 05/03/2023]
Abstract
Pharmaceuticals, including the lipid regulator gemfibrozil and the non-steroidal anti-inflammatory drug diclofenac have been identified in waste water treatment plant effluents and receiving waters throughout the western world. The acute and chronic toxicity of these compounds was assessed for three freshwater species (Daphnia magna, Pseudokirchneriella subcapitata, Lemna minor) using standardised toxicity tests with toxicity found in the non-environmentally relevant mid mg L(-1) concentration range. For the acute endpoints (IC(50) and EC(50)) gemfibrozil showed higher toxicity ranging from 29 to 59 mg L(-1) (diclofenac 47-67 mg L(-1)), while diclofenac was more toxic for the chronic D. magna 21 d endpoints ranging from 10 to 56 mg L(-1) (gemfibrozil 32-100 mg L(-1)). These results were compared with the expression of several biomarkers in the zebra mussel (Dreissena polymorpha) 24 and 96 h after exposure by injection to concentrations of 21 and 21,000 μg L(-1) corresponding to nominal concentrations of 1 and 1000 μg L(-1). Exposure to gemfibrozil and diclofenac at both concentrations significantly increased the level of lipid peroxidation, a biomarker of damage. At the elevated nominal concentration of 1000 μg L(-1) the biomarkers of defence glutathione transferase and metallothionein were significantly elevated for gemfibrozil and diclofenac respectively, as was DNA damage after 96 h exposure to gemfibrozil. No evidence of endocrine disruption was observed using the alkali-labile phosphate technique. Results from this suite of biomarkers indicate these compounds can cause significant stress at environmentally relevant concentrations acting primarily through oxidation pathways with significant destabilization of the lysosomal membrane and that biomarker expression is a more sensitive endpoint than standardised toxicity tests.

Abstract
Abstract
Background: Ultraviolet radiation (UVR) exposure is the most important environmental risk factor for non-melanoma skin cancer (NMSC), comprised of basal (BCC) and squamous (SCC) cell carcinomas. However, the precise relationship between UVR exposure and skin cancer may differ by NMSC type. A case-control study was conducted to evaluate the relationship between patterns and timing of sun exposure and BCC/SCC. Methods: Study participants included histologically confirmed BCC (n=218) and SCC (n=169) cases recruited from a university dermatology clinic and control subjects who underwent a skin cancer screening exam and screened negative for and had no history of cancer (n=316). Information on patterns (intermittent vs. continuous) and timing (childhood vs. adulthood) of sun exposure was obtained from self-administered questionnaires. Associations with BCC/SCC were estimated by odds ratios (OR) and 95% confidence intervals (CI) calculated using logistic regression. Backward stepwise elimination was used to obtain the most parsimonious models that best fit the data. Final main effect models were adjusted for the following factors: age, sex, ethnicity, education, eye and hair color, smoking status, skin sensitivity to sun exposure, sun exposure protection behaviors, and history of dysplastic nevi and actinic keratosis. Results: History of blistering sunburn, a marker of intermittent sun exposure, was significantly positively associated with BCC (OR=2.08, 95% CI=1.19-3.64), but no association was observed with SCC (OR-1.37, 95% CI=0.69-2.69). Compared to reporting no moles on one's forearm, reporting ≥ 10 moles, a marker of increased childhood sun exposure, was positively associated with SCC (OR=5.37, 95% CI=1.11-26.0) but not BCC (OR=0.43, 95% CI=0.07-2.59). High levels of continuous sun exposure (5-6 hours versus <1 hour per day spent continuously during the week and on the weekend) was positively associated with SCC in one's teenage years (OR-5.14, 95% CI=0.63-41.8), twenties (OR=11.7, 95% CI=1.21-141.0), thirties (OR=6.17, 95% CI=1.01-37.8), and the ten years prior to study enrollment (OR=5.12, 95% CI=0.64-41.2). For BCC, associations with high levels of continuous sun exposure were observed in one's twenties (OR=4.80, 95% CI=1.10-21.0) and thirties (OR=6.66, 95% CI=1.23-35.4), but similar associations were not observed in one's teenage years (OR=1.29, 95% CI=0.28-5.88) and the past 10 years prior to study enrollment (OR=1.40, 95% CI=0.36-5.49). Conclusions: The associations between UVR and NMSC may differ by patterns and timing of sun exposure. Specifically, intermittent sun exposure appears to be associated with BCC and chronic sun exposure with SCC. Additionally, we observed sunlight exposure in adulthood to be associated with BCC while lifetime sun exposure was associated with SCC, in our study population.
