Impact of in utero tobacco exposure on fetal growth: Amount of exposure and second trimester fetal growth measurements.

BACKGROUND: Research reveals small and inconsistent findings linking prenatal tobacco exposure and early fetal growth, but failure to consider confounding and amount of exposure many explain inconsistencies. GOAL: To examine whether fetal growth effects following exposure to tobacco are evident in the second trimester, specific to certain growth parameters, and dose dependent. METHODS: Participants were pregnant women (64 smokers, 100 controls) with no other drug use. Available data included background/medical information and ultrasound measurements coded as percentiles. RESULTS: Controlling for background differences, 10+ cig/day predicted a 10+ percentile point reduction in estimated fetal weight, femur length, head circumference, and biparietal diameter compared to non-exposed controls. Exposure to <10 cig/day predicted significant reduction in only biparietal diameter. Exposure was unrelated to abdominal circumference. CONCLUSIONS: Results demonstrate utility of considering amount of exposure when examining/quantifying fetal growth effects, and suggest even reduction in early pregnancy smoking may positively benefit aspects of fetal development.

Birth outcomes following in utero co-exposure to tobacco and marijuana.

BACKGROUND: With recent changes in tobacco and marijuana use patterns, it becomes crucial to understand how the prenatal co-use of these substances impacts birth outcomes. The goal of this study was to examine the risk of adverse birth outcomes among infants born to women who used tobacco and marijuana concurrently throughout pregnancy compared to infants of women who used tobacco alone. METHODS: This study involved a retrospective chart review of pregnant women identified via self-report or biochemical testing who used tobacco products alone (N = 71) or tobacco and marijuana simultaneously (N = 127) at any point throughout pregnancy. Differences in birth outcomes between these groups, including APGAR (appearance, pulse, grimace, activity, and respiration) scores, respiratory distress, neonatal intensive care unit admission, intrauterine growth restriction, birth weight, birth length, head circumference, gestational age, and length of hospital stay, were analyzed using linear regression and odds ratio analysis. RESULTS: There were no significant differences in outcomes for infants of women who used tobacco and marijuana compared to infants of women who used tobacco alone during pregnancy. Rates of adverse birth outcomes were high among women who used tobacco compared to what would be expected in unexposed pregnancies. CONCLUSIONS: Tobacco and marijuana co-use during pregnancy was not associated with an additional risk of adverse birth outcomes compared to tobacco use alone. Women should be educated on potential risks of marijuana, and especially, tobacco use during pregnancy. These results will inform clinical recommendations for pregnant women using tobacco and marijuana, aiming to decrease preventable adverse outcomes for patients and infants.

Sexual Coercion, Intimate Partner Violence, and Homicide: A Scoping Literature Review.

The specific relationship between sexual coercion, intimate partner violence (IPV) during pregnancy, and intimate partner homicide (IPH) is poorly understood. Through a scoping literature review, we identified 101 studies on sexual coercion, IPV during pregnancy, and IPH and created a conceptual model suggesting unintended pregnancies may serve as both a risk factor for and a product of IPV that may escalate to IPH. We illustrate a healthcare systems intervention implication of this model in the context of the Colorado Family Planning Initiative (CFPI). Descriptive statistics suggest an inverse association between contraception access and IPH, which declined by 62% during the first 4 years of the CFPI. Interventions aimed at improving reproductive agency, including improving contraception access and reducing unintended pregnancy, may be a useful opportunity for clinician and health systems to contribute to reducing both lethal and nonlethal IPV.

Sociodemographic Disparities in the Diagnosis and Prognosis of Patients With Cervical Cancer: An Analysis of the Surveillance, Epidemiology, and End Results Program.

Background While the incidence and mortality rates of cervical cancer are declining due to improved prevention, screening, and treatment, inequitable access to care may contribute to worse patient outcomes. Therefore, we sought to evaluate sociodemographic disparities in the diagnosis and prognosis of patients with cervical cancer. Methodology The Surveillance, Epidemiology, and End Results (SEER) database was queried for adult women diagnosed with cervical cancer from 2010 to 2015. Sociodemographic groups of interest included patient race/ethnicity (non-Hispanic White/Hispanic White/Black/Other), residential setting (rural/urban), and county median household income (<$45,000/$45,000-59,999/$60,000-74,999/≥$75,000). Outcomes of interest included stage at diagnosis, receipt of hysterectomy, and overall survival (OS). Outcomes were evaluated using Pearson's chi-square test, multivariable logistic regression, and multivariable Cox proportional hazards. Results A total of 5,726 patients were identified with an average age of 50.1 years (SD = 14.6). Significant differences in cancer stage at diagnosis were identified based on race/ethnicity (p < 0.001) and household income (p = 0.012). On adjusted analysis, Black patients were found to be significantly less likely to receive a hysterectomy compared to non-Hispanic White patients (odds ratio (OR) = 0.46; 95% confidence interval (CI) = 0.37-0.56). Lower household income was associated with poorer survival for stage I (<$45,000 vs. >$75,000: hazard ratio (HR) = 1.53; 95% interquartile range (IQR) = 1.00-2.33), II ($45,000-59,999 vs. >$75,000: HR = 1.67; 95% IQR = 1.19-2.35), and IV (<$45,000 vs. >$75,000: HR = 1.64; 95% IQR = 1.22-2.29) disease. Black race was associated with poorer OS for stage IV disease (HR = 1.29; 95% IQR = 1.06-1.56). Conclusions This study highlights significant disparities in disease progression at diagnosis and OS for cervical cancer patients based on race/ethnicity and household income. These findings may assist policymakers in developing strategies for mitigating these disparities.

The Impact of Pregnancy on Diabetic Retinopathy: A Single-Site Study of Clinical Risk Factors.

INTRODUCTION: This study aimed to provide information on modifiable and non-modifiable risk factors for the progression and development of diabetic retinopathy (DR) and diabetic macular edema (DME). This retrospective chart review case-control study was designed to provide perspective on clinical variables. METHODS: Single-center study analysis was completed with chart review, identifying 50 patients (100 eyes) ultimately included in the final analysis. Included patients were women with type 1 or 2 diabetes that entered prenatal care and had a delivery from January 2010 to December 2022. The primary outcome measure was clinical variables between progression and no progression groups. Data were analyzed via χ2 analysis and independent samples t test when appropriate. Significantly different variables were further analyzed by binary logistic regression. RESULTS: The DR progression group had significantly higher prepregnancy HbA1c levels (9.9) when compared to the no progression group (8.5, p value 0.028). DR progression group also had higher rates (51.9%) of full-term births. The DME progression group had significantly higher rates of type 2 diabetics (100%) compared to the no progression group (30.9%, p value 0.029). Hypertension treatment before (81.8%; p value 0.008) pregnancy was also more common in the DME progression group. Intravitreal injections were more common in patients with visual acuity deterioration (26.7%, p value 0.046). The average number of fetal complications was significantly higher in the visual acuity non-worsening group (1.1) compared to the progression group (0.5, p value 0.04). These variables were not statistically significant after entry into multivariate analysis. DISCUSSION: Severity and treatment of retinopathy before pregnancy, type of diabetes, and blood pressure control are all significant factors affecting the progression and development of severe ocular complications in pregnancy.

The COVID-19 pandemic and the experience of postpartum depression.

Background: Early studies assessing peripartum mood disorders during the COVID-19 pandemic have conflicting results.Objective: The primary aim was to examine if postpartum depression (PPD) was more common or more severe during the COVID-19 pandemic compared to earlier periods, and to assess what individual factors may worsen the impact of the pandemic.Methods: Electronic health records at an academic pediatric practice in Michigan identified 242 biological mother-child dyads with delivery between 1/1/2017 and 12/31/2021. PPD was evaluated using the Edinburgh Postnatal Depression Scale (EPDS) during well-child visits. Participants were divided into three groups for analysis: Pre-Pandemic (n = 100), Early Pandemic (n = 93), and Later Pandemic (n = 49). Logistic regression analysis was used to predict PPD development, controlling for background factors.Results: After controlling for confounders, the three groups did not differ significantly. Preexisting mental health conditions was a significant (p<.001) moderator; PPD rates peaked early in the pandemic (60%), compared to late pandemic (42%) and pre-pandemic (36%). Women without a mental health diagnosis pre-pregnancy experienced the lowest levels of PPD during the pandemic.Conclusions: Rates of PPD were not significantly affected by the COVID-19 pandemic for most women. However, biological mothers with preexisting mental health conditions had significantly higher rates of PPD.

In utero effects of opioids on fetal growth.

BACKGROUND: Studies indicate antenatal opioid use is associated with birth size deficits, as evidenced by reductions in birth weight and head circumference. However, there remains a limited understanding of how early this growth restriction occurs, and what specific parameters are affected. This novel study evaluated global and specific growth deficits associated with prenatal opioid exposure between 18-22 weeks' gestation as assessed during anatomy ultrasounds. METHODS: Pregnant women who completed an anatomy ultrasound were identified via electronic medical records from a large academic obstetric practice. The study group used opioids, with tobacco and/or marijuana use permitted (n = 41). The control group could have used tobacco and/or marijuana, but not opioids (n = 308). Neither group had alcohol or other drug exposure. Records were reviewed for medical history and ultrasound size parameters, coded as percentiles for gestational age. RESULTS: Demographics and medical histories were compared with several significant differences noted. After controlling for these differences, significant (p < 0.05) growth deficits were identified in opioid-exposed fetuses. Specifically, reductions >10 percentile points were observed in head circumference, biparietal diameter, and humerus length for opioid-exposed fetuses compared to controls. Additionally, intrauterine growth restriction (IUGR) was diagnosed five times more often. Femur length was significantly reduced in opioid-exposed fetuses prior to adjustment for confounding (p = .016), but this reduction was not significant (p = .072) after controlling for background differences. Estimated fetal weight (p = .274) and abdominal circumference (p = .633) were not significantly different between exposure groups. CONCLUSION: Fetal opioid exposure predicted various bone growth deficits during routine anatomy ultrasound, indicating the effects of opioid exposure on size deficits may be evident as early as 18-22 weeks' gestation. These findings may also suggest that in utero opioid exposure negatively impacts bone growth specifically rather than weight or fat/muscle mass. Additional studies with larger sample sizes may also reveal significantly reduced femur length, further supporting a negative impact on bone growth. Future studies evaluating bone health and immune function in children after antenatal opioid exposure may help clarify this specific effect of opioids on bone development.

The impact of timing of in utero marijuana exposure on fetal growth.

Objective: To examine whether timing of in utero marijuana exposure independently and negatively impacts fetal growth, and if these effects are global or specific to certain growth parameters. Study design: The two study groups were marijuana users (N = 109) and a randomly selected control group of biochemically verified non-users (n = 171). Study data were obtained via manual abstraction of electronic medical records. Results: After control for significant confounders, regression results indicated significant (p < .05) decrease in newborn weight following first trimester marijuana exposure only (-154 g) and following marijuana exposure throughout gestation (-185 g) compared to controls. There were also significant deficits in head circumference following marijuana exposure in the first and second trimester only (-.83 cm) and marijuana exposure throughout pregnancy (-.79 cm) compared to controls. Newborn length was not significantly predicted by marijuana exposure. Conclusions: Timing of marijuana exposure appears to play a key role in specific fetal growth deficits, with exposure throughout gestation most detrimental. However even first trimester exposure may result in decreased weight. Timing and amount of use could be confounded in this study as those who quit early in pregnancy may have been lighter users than those who continued throughout pregnancy. More research is clearly needed to better understand the role of amount and timing of in utero marijuana exposure in predicting different aspects of fetal growth, however, this study suggests that women should be encouraged to avoid marijuana use at any point in pregnancy.

Polypharmacy Prevalence and Perceptions of Deprescribing in Elderly Patients Among Community Primary Care Providers in Mid-Michigan Practices.

INTRODUCTION: Polypharmacy is common among the elderly and can predispose them to increased morbidity and higher healthcare expenditures. Deprescribing is an important aspect of preventative medicine to minimize polypharmacy-related adverse effects. Mid-Michigan has historically been considered a medically underserved area. We sought to describe polypharmacy prevalence and primary care provider (PCP) perceptions of deprescribing in the elderly at community practices in the region. METHODS: Medicare Part D claims data from 2018 to 2020 were queried to calculate the prevalence of polypharmacy, which is defined as Medicare beneficiaries who were concurrently prescribed at least five medications. PCPs from four community practices in adjacent counties in mid-Michigan, including two high- and two low-prescribing practices, were surveyed to assess their perceptions of deprescribing. RESULTS: The prevalence of polypharmacy in two adjacent mid-Michigan counties was 44.0% and 42.5%, which was similar to Michigan's overall prevalence of 40.7% (p = 0.720 and 0.844, respectively). Additionally, 27 survey responses were received from mid-Michigan PCPs (response rate, 30.7%). Most respondents expressed confidence in deprescribing in the elderly from a clinical standpoint (66.7%). Barriers to deprescribing included patient/family concerns (70.4%) and lack of time during office visits (37.0%). Facilitators to deprescribing included patient readiness (18.5%), collaboration with case managers/pharmacists (18.5%), and up-to-date medication lists (18.5%). An exploratory comparison of perceptions at high- and low-prescribing practices showed no significant differences. CONCLUSION: These findings demonstrate a high prevalence of polypharmacy in mid-Michigan and suggest that PCPs in the region are generally supportive of deprescribing. Potential targets to improve deprescribing in patients with polypharmacy include addressing visit length, patient/family concerns, increasing interdisciplinary collaboration, and medication reconciliation support.

Can umbilical cord testing add to maternal urine drug screen for evaluation of infants at risk of neonatal opioid withdrawal syndrome?

OBJECTIVE: This study evaluated maternal urine drug screen (UDS) at delivery and umbilical cord drug testing and its association with neonatal opioid withdrawal syndrome (NOWS) diagnosis and severity following opioid exposed pregnancy. METHODS: A retrospective chart review of 770 mother-infant dyads at five birthing hospitals in the United States Appalachian region for a five-year period was performed. Variables of interest included dyad demographics, results of maternal UDS at delivery and umbilical cord drug testing, and three neonatal outcomes: NOWS diagnosis, pharmacologic treatment administered for NOWS, and length of hospital stay (LOS) of the newborn. RESULTS: Opioid-positivity was between 8.5% and 66.3% based on maternal UDS at delivery or umbilical cord testing. Odds of NOWS diagnosis and increased infant LOS was best associated with opioid detection in maternal UDS alone (OR = 5.62, 95% CI [3.06, 10.33] and OR = 8.33, 95% CI [3.67, 18.89], respectively). However, odds of pharmacologic treatment for NOWS was best associated with opioid detection in both maternal UDS and umbilical cord testing on the same dyad (OR = 3.22, 95% CI [1.14, 9.09]). CONCLUSION: Maternal UDS is a better option compared to umbilical cord testing for evaluation of opioid-exposed infants and risk of NOWS diagnosis and increased infant LOS.

Prenatal marijuana exposure and visual perception in toddlers: Evidence of a sensory processing deficit.

Background: Research has identified a link between prenatal marijuana exposure and multiple outcomes in children, including cognitive development. Several studies have found specific differences in sensory processing and attention, with visual perception especially impacted in school age children. The current study explored whether this effect is evident at an earlier age, and thus our goal was to investigate the relationship between in-utero marijuana exposure and sensory processing capabilities in toddlers. We hypothesized that in-utero marijuana exposure throughout pregnancy would specifically predict visual sensory hyperactivity in children as young as 15 months of age. Methods: Participants were 225 15-month-old children whose mothers were recruited during pregnancy. Substance exposure was prospectively collected and biochemically verified, with marijuana coded as no exposure, 1st trimester exposure only, or exposure throughout pregnancy. The Infant Toddler Sensory Profile evaluated 5 domains of sensory processing (visual, auditory, tactile, vestibular, oral). Results: Prenatal marijuana exposure throughout pregnancy, but not when limited to the first trimester, predicted a two-fold increased likelihood of scoring in a range indicating high levels of seeking out and potentially over-attending to visual stimulation after controlling for potentially confounding factors including other prenatal exposures. Marijuana exposure was not significantly related to other processing domains. Conclusion: Results indicate that links previously identified between prenatal marijuana exposure and visual function and attention may already be evident at 15 months of age, and also suggest an impact related to continuous/later pregnancy exposure. Our findings, as well as those from previous studies, all suggest visual processing differences for exposed children, differences that may predict emerging issues with visual attention and habituation. As legalization of marijuana continues to increase, further research is clearly needed to examine specific teratologic effects associated with use during pregnancy.

Evidence for concealed fasciculo-ventricular connections as revealed by His bundle pacing.

BACKGROUND: It is almost 100 years ago since Mahaim described the so-called paraspecific connections between the ventricular conduction axis and the crest of the muscular ventricular septum, believing such pathways to be ubiquitous. These pathways, however, have yet to be considered as potential pathways for septal activation during His bundle pacing. MATERIALS: So as to explore the hypothesis that specialised septal pathways might provide the substrate for septal activation during His bundle pacing, we compared the findings from 22 serially sectioned histological datasets and 34 different individuals undergoing His bundle pacing. RESULTS: We found histologically specialised pathways connecting the branching component of the atrioventricular conduction axis with the crest of the muscular ventricular septum in almost four-fifths of the histological datasets. In 32 of 34 patients undergoing His bundle pacing, the QRS complex closely resembled published images of known conduction through fasciculo-ventricular pathways. In only two patients was a delta wave not seen at any pacing voltages. Capture of these connections varied according to pacing voltage, a finding which correlated with the distance of the pathways from the site of penetration of the ventricular conduction axis. Ventricular activation times remained normal in the presence of the delta wave at higher pacing voltage but were prolonged at lower voltages. CONCLUSIONS: Our histologic findings confirm fasciculo-ventricular connections, initially described by Mahaim as being paraspecific, are likely ubiquitous. Analysis of 12-lead electrocardiograms leads us to conclude that fasciculo-ventricular pathways, concealed during sinus rhythm, become manifest with His bundle pacing.

Comparative admission rates and infection severity of COVID-19 among unvaccinated and vaccinated patients.

Vaccination efforts have limited the burden of the pandemic caused by the coronavirus disease 2019 (COVID-19) with substantial evidence showing reduced hospitalization rates among vaccinated populations. However, few studies have explored correlations between vaccination status and inpatient COVID-19 outcomes. This observational case-control study involved a retrospective chart review of adult patients hospitalized for COVID-19 infection at a medium-sized hospital in Central Michigan between May 1, 2021 and September 30, 2021. Unadjusted analyses involved t-tests and chi-square tests followed by adjusted analyses using binary logistic and linear regression models. Of the 192 screened patients, 171 subjects met the inclusion criteria. Vaccinated patients were significantly older (71.09 vs 57.45, p < 0.001), more likely to identify as white (89.4% vs 66.9%, p = 0.026), and had a lower baseline 10-year survival rate predicted by the Charlson Comorbidity Index (42% vs 69%, p < 0.001) compared to unvaccinated patients. Common symptoms between both groups included shortness of breath (50%), malaise (23%-37%), cough (28%-32%), and fever or chills (25%). Upon matching, adjusted analysis showed significantly higher rates of remdesivir administration to unvaccinated patients (41.3% vs 13.3%, odds ratio (OR): 4.63, 90% confidence interval (CI): 1.98-11.31). Despite higher intensive care unit admission rates among unvaccinated patients (39.1% vs 23.9%, OR: 1.83, 90% CI: 0.74-4.64), this difference did not reach statistical significance. Accordingly, immunization status strongly correlates with patient demographics and differences in inpatient treatment. Larger studies are needed to further assess the vaccine's impact on inpatient outcomes outside of our community.

Eating disorder risk in rural US adolescents: What do we know and where do we go?

Adolescence is a vulnerable period for the development of eating disorders, but there are disparities in eating disorder risk among adolescents. One population that may be at increased risk but is vastly understudied, is adolescents residing in rural regions within the United States. Rural communities face many mental and physical health disparities; however, the literature on rural adolescent eating disorder risk is nearly nonexistent. In this paper we summarize the scant literature on disordered eating and eating disorder risk and prevalence among rural US adolescents. We also detail eating disorder risk factors that may have unique influence in this population, including socioeconomic status, food insecurity, healthcare access, body image, and weight stigma. Given the presence of numerous eating disorder risk factors, we speculate that rural adolescents may be a particularly vulnerable population for eating disorders and we propose critical next steps in research for understanding eating disorder risk among the understudied population of rural adolescents. PUBLIC SIGNIFICANCE: Rural adolescents may be at increased risk for eating disorders due to disproportionate burden of known risk factors, though this relationship remains understudied. We present a summary of the literature on prevalence and unique risk factors, proposing that this may be a high-risk population. We detail next steps for research to understand eating disorder risk in this population to inform future prevention, identification, and treatment efforts needed in this community.

Risk factors for the development or progression of diabetic retinopathy in pregnancy: Meta-analysis and systematic review.

BACKGROUND: Diabetic retinopathy (DR) is the leading cause of blindness in the working-age population, and it increases in severity during pregnancy. METHODS: Systematic review of literature from PubMed, Cochrane Library and Web of Science using keywords 'diabetic retinopathy' and 'pregnancy' and 'progression' from inception to 2021 was completed. Included studies were (1) peer-reviewed observational studies addressing progression/development of DR in pregnancy, (2) provided the number of diabetic patients that developed/progressed in DR during pregnancy, and (3) included differential data on variables between progression and non-progression groups. This was applied by two independent researchers and referred to a third researcher as necessary. Twenty-seven of the original 138 studies met this criterion. Data were pooled and analysed using fixed-effects in meta-analysis. RESULTS: From 27 studies, 2537 patients were included. Pre-eclampsia [Risk Ratio (RR) 2.62 (95% CI = 1.72, 4.00)] and hypertension treatment during pregnancy [RR 2.74 (95% CI = 1.72, 4.00)] were significantly associated with the development/progression of DR. HbA1c at baseline [MD 0.82 (95% CI = 0.59, 1.06)], duration of diabetes [mean difference (MD) 5.97 (95% CI = 5.38, 6.57)], and diastolic blood pressure at baseline [MD 3.29 (95% CI = 0.46, 6.12)] were all significantly higher in the progression group while only mean birth weight [MD -0.17 (95% CI = -0.31, -0.03)] was significantly higher in the non-progression group. CONCLUSIONS: This study fills a gap in the literature and provide physicians with more information on the risk factors associated with the progression of DR in pregnancy and how to counsel this vulnerable patient population appropriately.

Prenatal Buprenorphine/Naloxone or Methadone Use on Neonatal Outcomes in Michigan.

Background Maternal opioid exposure during pregnancy has various effects on neonatal health. Buprenorphine/naloxone and methadone are examples of medications for opioid use disorder (MOUD) used for the treatment of opioid use disorder (OUD). Research comparing the impacts of these MOUD modalities on neonatal outcomes when used to treat pregnant people with OUD remains limited. We evaluated the differences in outcomes between neonates with in-utero exposure to buprenorphine/naloxone versus methadone. Methodology We performed a retrospective cohort chart review between October 15, 2008, and October 15, 2019, evaluating mother/neonate dyads at two medical centers in Michigan. The charts of female patients, aged 18+, with OUD and buprenorphine/naloxone or methadone treatment, were examined. The charts of the corresponding neonates were also examined. Multiple regression analysis was performed. Results In total, 343 mother/infant dyads were included: 99 patients were treated with buprenorphine/naloxone and 232 patients were treated with methadone. The buprenorphine/naloxone group had significant differences in maternal age, hepatitis status, asthma, gestational age in weeks, neonatal intensive care unit (NICU) length of stay (LOS), neonatal opioid withdrawal syndrome (NOWS) peak score, birth head circumference, and birth weight compared to the methadone group at baseline. Adjusted multivariable regression analysis demonstrated neonates with exposure to buprenorphine/naloxone had a NOWS peak score 3.079 points less (95% confidence interval (CI): -4.525, 1.633; p = 0.001) and NICU LOS 8.955 days less (95% CI: -14.399, -3.511; p = 0.001) than neonates exposed to methadone. Conclusions Neonates with in-utero exposure to buprenorphine/naloxone had significantly lower NOWS scores and shorter NICU LOS compared to neonates with in-utero exposure to methadone. These findings demonstrate that buprenorphine/naloxone is potentially a more favorable treatment for the reduction in metrics representing adverse neonatal outcomes in pregnant people with OUD than methadone.

The Effect of Infection Precautions on Extended-Spectrum Beta-Lactamase Enterobacteriaceae Colonization Among Nurses in Three Beirut Hospitals.

Background and objective Extended-spectrum beta-lactamase-producing Enterobacteriaceae (ESBL-PE) are rapidly emerging worldwide. This study aimed to assess the effect of contact precaution (CP) on ESBL-PE-colonization rates among nurses in three hospitals in Beirut, Lebanon, where ESBL is endemic, in order to define the risk factors for colonization. Accordingly, the ongoing use of CP to prevent ESBL-PE transmission to healthy nurses was evaluated. Methods This cross-sectional study was conducted in three hospitals. Hospital 1 required CP, Hospital 2 had recently stopped CP, and Hospital 3 had stopped it three years previously. Questionnaires and stool-collection containers were distributed to all patient care nurses in those three hospitals. The Returned samples were tested using the agar dilution technique. Results A total of 269 out of 733 nurses volunteered to participate; 140 met the inclusion criteria (no recent hospitalization, antibiotic use, or known ESBL-PE colonization) and provided samples. Among them, 15% were ESBL-positive. Compared to nurses from Hospital 3, nurses from Hospital 1 were 59% less likely to be colonized, while nurses from Hospital 2 were 62% more likely to be colonized. Conclusion In hospitals where CP is in place for ESBL-positive patients, ESBL-PE prevalence in nursing staff was significantly lower. Additionally, a work experience of two to four years increased the odds of ESBL-PE colonization in comparison with longer nursing experience. CP may be a justifiable means of protection against ESBL-PE transmission to healthy nurses. The risk factors for colonization were discontinuation of CP and a shorter clinical work experience.

Prevalence of Opioid Use and Intimate Partner Violence among Pregnant Women in South-Central Appalachia, USA.

Background: Recent research indicates that pregnant women in rural communities are at increased risk of experiencing IPV and comorbid illicit opioid use compared to urban-residing pregnant women. Few studies of the interactions among rurality, substance use, and victimization in pregnant women exist. The current study sought to examine the relationship between IPV and opioid use and the interaction effects of rurality in Appalachian pregnant women. Methods: A convenience sample of pregnant women who were enrolled in a smoking cessation research study was used for this analysis. Participants included 488 pregnant women from five prenatal clinics in South-Central Appalachia. Data were from self-reported assessments and semi-structured interviews on substance use and IPV conducted from first trimester of pregnancy through eight months postpartum. Results: Four hundred and ten participants reported experiencing any form of IPV in the past year. Logistic regression results indicated that physical IPV was associated with opioid use, but sexual and psychological IPV were not. The moderation model indicated direct effects between IPV and opioid use, but were not moderated by rurality. Conclusion: This study suggests a need to further understand the relationship between substance use, IPV, and rurality in pregnant women. The specific subtopic of opioid use by pregnant women living in rural communities, and its relationship to IPV victimization and adverse fetal and maternal health outcomes, continues to be an understudied, but critically important area. Limitations and future directions pertaining to IPV screenings and interventions for pregnant women are discussed.

Impact of in utero opioid exposure on newborn outcomes: beyond neonatal opioid withdrawal syndrome.

BACKGROUND AND OBJECTIVES: Research on in utero opioid exposure impacts has focused on Neonatal Opioid Withdrawal Syndrome (NOWS). However, possible impacts on fetal growth and newborn wellbeing have emerged, with inconsistencies likely driven by methodological issues. Our goal was to compare birth outcomes between newborns with prenatal opioid exposure and a matched control group. METHODS: Participants were identified via manual review of electronic medical records of all deliveries over five years within a regional health system (6 delivery hospitals across 2 states). From over 18,000 births, 300 with prenatal opioid exposure and 300 control newborns matched on exposure, medical, and background factors were included. Additional factors were statistically controlled. Outcomes included pregnancy/delivery complications, newborn size, and newborn health complications. RESULTS: Compared to biochemically verified controls, exposed newborns had higher rates of fetal growth restriction, weighed less, had decreased length and head circumference, and had higher rates of respiratory distress, sepsis, and jaundice. No significant differences in gestational length, Apgar scores, or neonatal hypoglycemia were found. Adjusted regression analyses revealed that compared to controls, those exposed had an average 150 g decrease in birth weight, a two-fold increased risk for IUGR (OR = 2.09), a nearly three-fold (OR = 2.80) increased risk for jaundice, a more than seven-fold (OR = 7.40) increased risk for respiratory distress, and a thirty-fold (OR = 30.47) increased risk for sepsis. CONCLUSIONS: Results suggest significant pregnancy and newborn outcomes beyond NOWS following pregnancy opioid use, informing clinical screening and treatment decisions to enhance health and wellbeing in pregnancy, during the neonatal period, and beyond.

Investigation of factors that predict risk for hospital readmission following delivery of pregnancies complicated by hypertensive disorders of pregnancy.

OBJECTIVE: The aim of this study was to evaluate specific risk factors and their impact on hospital readmission risk following delivery in pregnancies affected by the hypertensive disease of pregnancy (HDP). METHODS: We performed a 10-year case-control study for patients who delivered at our institution and whose antenatal courses were complicated by HDP. The primary outcome was the identification of specific patient factors contributing to readmission. HDP pregnancies experiencing readmission for HDP signs and/or symptoms were used as the cases, with HDP pregnancies not experiencing readmission randomly selected as controls. Maternal age, gestational age at delivery, gravidity, parity, and mode of delivery (vaginal including operative, or cesarean) were recorded. Mean systolic and diastolic blood pressures were calculated over the 24 h preceding discharge. The most recent laboratory values preceding discharge for serum creatinine, lactate dehydrogenase, aspartate aminotransferase, alanine transaminase, and platelets were also recorded. The presence or absence of prescribed antihypertensive medication was recorded for initial hospitalization. Postpartum readmission was defined as within 30 days of delivery. Exclusion criteria involved readmission for non-HDP cause and maternal age less than 17 at delivery. RESULTS: Within the study timeframe, 3601 patients with pregnancies complicated with HDP were identified. Of these, 34 patients were readmitted within 30 days postpartum for signs and/or symptoms of HDP after exclusion criteria were applied A cohort of 50 controls were used for comparison for a total of 84 participants. A diagnosis of pre-eclampsia was significantly associated with readmission (p=.004) when compared to other HDP diagnoses. Demonstration of severe disease features also was associated significantly (p < 0.001) with readmission. Parity greater than or equal to three also was associated with readmission (p = 0.019). Notably, age, BMI, delivery mode, blood pressure preceding discharge, length of hospital stay, and being discharged with antihypertensive medication were not significantly associated with readmission. CONCLUSION: This study suggests that readmission overall for the hypertensive disease of pregnancy is rare, but that patient variables of increasing parity and presence of severe features were associated with postpartum readmission. Knowledge of these variables may assist physicians in the identification of HDP patients who are at higher risk for readmission.
