Abstract
Importance People with a history of incarceration may experience barriers in access to and receipt of health care in the US. Objective To examine the associations of incarceration history and access to and receipt of care and the contribution of modifiable factors (educational attainment and health insurance coverage) to these associations. Design, Setting, and Participants Individuals with and without incarceration history were identified from the 2008 to 2018 National Longitudinal Survey of Youth 1979 cohort. Analyses were conducted from October 2022 to December 2023. Main Measures and Outcomes Access to and receipt of health care were measured as self-reported having usual source of care and preventive service use, including physical examination, influenza shot, blood pressure check, blood cholesterol level check, blood glucose level check, dental check, and colorectal, breast, and cervical cancer screenings across multiple panels. To account for the longitudinal study design, we used the inverse probability weighting method with generalized estimating equations to evaluate associations of incarceration history and access to care. Separate multivariable models examining associations between incarceration history and receipt of each preventive service adjusted for sociodemographic factors; sequential models further adjusted for educational attainment and health insurance coverage to examine their contribution to the associations of incarceration history and access to and receipt of health care. Results A total of 7963 adults with 41 614 person-years of observation were included in this study; of these, 586 individuals (5.4%) had been incarcerated, with 2800 person-years of observation (4.9%). Compared with people without incarceration history, people with incarceration history had lower percentages of having a usual source of care or receiving preventive services, including physical examinations (69.6% vs 74.1%), blood pressure test (85.6% vs 91.6%), blood cholesterol level test (59.5% vs 72.2%), blood glucose level test (61.4% vs 69.4%), dental check up (51.1% vs 66.0%), and breast (55.0% vs 68.2%) and colorectal cancer screening (65.6% vs 70.3%). With additional adjustment for educational attainment and health insurance, the associations of incarceration history and access to care were attenuated for most measures and remained statistically significant for measures of having a usual source of care, blood cholesterol level test, and dental check up only. Conclusions and Relevance The results of this survey study suggest that incarceration history was associated with worse access to and receipt of health care. Educational attainment and health insurance may contribute to these associations. Efforts to improve access to education and health insurance coverage for people with an incarceration history might mitigate disparities in care.

Abstract
INTRODUCTION Several organizations now recommend average risk individuals begin colorectal cancer (CRC) screening at age 45 instead of 50 years. We present contemporary estimates of CRC screening in newly eligible adults ages 45-49 years between 2019-2021. METHODS Nationally representative prevalence estimates and population number screened were estimated from the National Health Interview Survey. A logistic regression model assessed CRC screening prevalence differences by survey year and sociodemographic characteristics. RESULTS In 2021, 19.7%, or fewer than 4 million of the eligible 19 million adults ages 45-49 years, were up-to-date for CRC screening. Screening was lowest in uninsured (7.6%), less than a high school diploma (15.4%), and Asian (13.1%) persons. Additionally, FOBT/FIT testing was under-utilized with only 2.4% (< 460 thousand persons) reporting being screened up-to-date with this modality in 2021. DISCUSSION CRC screening in eligible young adults remains low. Concerted efforts to improve screening are warranted, particularly in underserved populations.

Abstract
Recent guidelines from the American Cancer Society stress HPV vaccination series initiation at the youngest opportunity, i.e., age 9 years. There are limited data on the association between initiating HPV vaccination at ages 9-10 years and up-to-date (UTD) status. In this study, we compare nationally representative UTD HPV vaccination rates between adolescents who initiated the series younger (ages 9-10 years) vs. older (≥ age 11 years). Five years of pooled data (2016-2020) from National Immunization Survey-Teen were used to estimate the UTD HPV vaccination prevalence among younger vs. older initiating 13-17-year-olds. Adjusted logistic regression models estimated prevalence ratios (aPRs), differences (aDs), and difference in differences (aDDs) in prevalence of being UTD to assess the overall association of age at initiation with being UTD and differences in sociodemographic predictors of being UTD among younger vs. older initiators. UTD prevalence for younger initiators was 93% compared with 72% among older initiators (aPR: 1.27,95%CI: 1.24,1.31). Among older initiators, UTD prevalence was significantly different by sex, insurance status, and current age; no such differences were observed among younger initiators. Results indicate that younger initiation is associated with a 27% higher UTD prevalence, highlighting the importance of promoting younger initiation, particularly among those with health-care barriers.

Abstract
PURPOSE To examine whether cancer screening prevalence in the United States during 2021 has returned to prepandemic levels using nationally representative data. METHODS Information on receipt of age-eligible screening for breast (women age 50-74 years), cervical (women without a hysterectomy age 21-65 years), prostate (men age 55-69 years), and colorectal cancer (men and women age 50-75 years) according to the US Preventive Services Task Force recommendations was obtained from the 2019 and 2021 National Health Interview Survey. Past-year screening prevalence in 2019 and 2021 and adjusted prevalence ratios (aPRs), 2021 versus 2019, with their 95% CIs were calculated using complex survey logistic regression models. RESULTS Between 2019 and 2021, past-year screening in the United States decreased from 59.9% to 57.1% (aPR, 0.94; 95% CI, 0.91 to 0.97) for breast cancer, from 45.3% to 39.0% (aPR, 0.85; 95% CI, 0.82 to 0.89) for cervical cancer, and from 39.5% to 36.3% (aPR, 0.9; 95% CI, 0.84 to 0.97) for prostate cancer. Declines were most notable for non-Hispanic Asian persons. Colorectal cancer screening prevalence remained unchanged because an increase in past-year stool testing (from 7.0% to 10.3%; aPR, 1.44; 95% CI, 1.31 to 1.58) offset a decline in colonoscopy (from 15.5% to 13.8%; aPR, 0.88; 95% CI, 0.83 to 0.95). The increase in stool testing was most pronounced in non-Hispanic Black and Hispanic populations and in persons with low socioeconomic status. CONCLUSION Past-year screening prevalence for breast, cervical, and prostate cancer among age-eligible adults in the United States continued to be lower than prepandemic levels in the second year of the COVID-19 pandemic, reinforcing the importance of return to screening health system outreach and media campaigns. The large increase in stool testing emphasizes the role of home-based screening during health care system disruptions. [Media: see text].

Abstract
INTRODUCTION E-cigarette use increased between 2014 and 2018 among younger U.S. adults who had never smoked combustible cigarettes, potentially increasing nicotine addiction risk and progression to combustible tobacco products. It is unknown how prevalence changed after the E-cigarette, or vaping, product use-associated lung injury epidemic (late 2019) and COVID-19 pandemic (March 2020) by age group and combustible cigarette smoking status. METHODS Data from cross-sectional, nationally representative National Health Interview Surveys in 2019, 2020, and 2021 (analyzed in 2022) were used to estimate current E-cigarette use prevalence, adjusted prevalence difference between survey years, and population counts, by age group (younger, 18-29 years, n=11,700; middle age, 30-44 years, n=21,300, 45-59 years, n=21,308; older, ≥60 years, n=36,224) and cigarette smoking status (current, former, and never). RESULTS E-cigarette use prevalence increased among younger adults between 2019 and 2021 (8.8%-10.2%, adjusted prevalence difference=1.7% points, 95% CI=0.1, 3.3), primarily owing to an increase among those who never smoked cigarettes (4.9%-6.4%, adjusted prevalence difference=1.7% points, 95% CI=0.3, 3.1). People who never smoked cigarettes constituted 53% (2.68 million) of younger adults who used E-cigarettes in 2021, increasing by 0.71 million from 2019. Conversely, among middle age and older adults, the prevalence was similar in 2019 and 2021 irrespective of cigarette smoking status, and those who formerly smoked cigarettes constituted the largest proportion of people who used E-cigarettes in 2021 (age 30-44 years: 51.8%, 1.8 million; age 45-59 years: 51.6%, 0.85 million; age ≥60 years: 47.5%, 0.45 million). CONCLUSIONS Efforts must address the rise in E-cigarette use among younger adults who never smoked cigarettes. At the same time, assistance is needed to help those who switched to E-cigarettes to stop smoking to transition to non-use of all products.

Abstract
We present national and state representative prevalence estimates of modifiable cancer risk factors, preventive behaviors and services, and screening, with a focus on changes during the COVID-19 pandemic. Between 2019 and 2021, current smoking, physical inactivity, and heavy alcohol consumption declined, and human papillomavirus vaccination and stool testing for colorectal cancer screening uptake increased. In contrast, obesity prevalence increased, while fruit consumption and cervical cancer screening declined during the same timeframe. Favorable and unfavorable trends were evident during the 2nd year of the COVID-19 pandemic that must be monitored as more years of consistent data are collected. Yet disparities by racial/ethnic and socioeconomic status persisted, highlighting the continued need for interventions to address suboptimal levels among these population subgroups.

Abstract
IMPORTANCE Health care was disrupted in the US during the first quarter of 2020 with the emergence of the COVID-19 pandemic. Early reports in selected samples suggested that cancer screening services decreased greatly, but population-based estimates of cancer screening prevalence during 2020 have not yet been reported. OBJECTIVE To examine changes in breast cancer (BC), cervical cancer (CC), and colorectal cancer (CRC) screening prevalence with contemporary national, population-based Behavioral Risk Factor Surveillance System (BRFSS) data. DESIGN, SETTING, AND PARTICIPANTS This survey study included respondents from the 2014, 2016, 2018, and 2020 BRFSS surveys who were eligible for BC (women aged 50-74 years), CC (women aged 25-64 years), and CRC (women and men aged 50-75 years) screening. Data analysis was performed from September 2021 to February 2022. EXPOSURES Calendar year. MAIN OUTCOMES AND MEASURES Self-reported receipt of a recent (defined as in the past year) BC, CC, and CRC screening test. Adjusted prevalence ratios (aPRs) comparing 2020 vs 2018 prevalence and 95% CIs were computed. RESULTS In total, 479 248 individuals were included in the analyses of BC screening, 301 453 individuals were included in CC screening, and 854 210 individuals were included in CRC screening, In 2020, among respondents aged 50 to 75 years, 14 815 (11.4%) were Black, 12 081 (12.6%) were Hispanic, 156 198 (67.3%) were White, and 79 234 (29.9%) graduated from college (all percentages are weighted). After 4 years (2014-2018) of nearly steady prevalence, past-year BC screening decreased by 6% between 2018 and 2020 (from 61.6% in 2018 to 57.8% in 2020; aPR, 0.94; 95% CI, 0.92-0.96), and CC screening decreased by 11% (from 58.3% in 2018 to 51.9% in 2020; aPR, 0.89; 95% CI, 0.87-0.91). The magnitude of these decreases was greater in people with lower educational attainment and Hispanic persons. CRC screening prevalence remained steady; past-year stool testing increased by 7% (aPR, 1.07; 95% CI, 1.02-1.12), offsetting a 16% decrease in colonoscopy (aPR, 0.84; 95% CI, 0.82-0.88) between 2018 and 2020. CONCLUSIONS AND RELEVANCE In this survey study, stool testing increased and counterbalanced a decrease in colonoscopy during 2020, and BC and CC screening modestly decreased. How these findings might be associated with outcomes is not yet known, but they will be important to monitor, especially in populations with lower socioeconomic status, who experienced greater screening decreases during the COVID-19 pandemic.

Abstract
Strong partnerships are essential to lead the innovative change needed to prepare future nurses who demonstrate quality and safety competence. Successful models involve senior leadership, a shared vision, mutual goals, mutual respect, and an access to shared knowledge. The academic-practice partnership between a private university-based school of nursing and its affiliated health care system facilitated the implementation of a new Accelerated Bachelor of Science in Nursing (ABSN) program track to provide a seamless education to practice pathway for graduate nurses educated with quality and safety competencies and to meet the workforce demands of the health care system. The academic-practice model is based on the Guiding Principles outlined by the American Association of Colleges of Nursing-American Organization of Nurse Leaders (AACN-AONL) Task Force on Academic Practice Partnerships. As a result of this partnership, 84% of the program's graduates accepted a position with the health care partner as an advanced medical-surgical nurse, and student outcomes in quality and safety competencies were encouraging.

Abstract
COVID-19 required innovative approaches to educating health professions students who could no longer attend in-person classes or clinical rotations. Interprofessional education (IPE) activities were similarly impacted. To replace an in-person IPE activity slated for this spring, nursing and medical students with similar levels of clinical experience came together to attend a synchronous virtual session focused on discharge planning. The class objectives focused on the IPEC competencies of Role/Responsibility and Interprofessional Communication. Discussion revolved around the discharge planning process for an elderly patient with multiple medical problems, as this is a time when interprofessional collaboration has a clear benefit to patients. Twenty-eight nursing students and eleven medical students attended a 90 min session via Zoom. Students received pre-readings, the day's agenda, learning objectives, and discussion questions in advance. The session had three sections: introduction/welcome, breakout sessions, and debrief and evaluation. Four faculty leaders and four students who participated in a similar in-person session in the past served as facilitators. They received a supplemental facilitator guide for use if students were not able to sustain their discussions for the allotted time. Materials can be accessed by contacting the corresponding author (BR). Students completed a post-session survey, and qualitative analysis demonstrated that they had addressed the two relevant IPEC competencies in their groups and showed evidence of touching on the additional two IPEC competencies as well. Overall, they enjoyed the experience. This virtual experience made scheduling simpler than planning an in-person session and allowed this activity to occur despite restrictions secondary to the pandemic. This might remain a useful format for similar sessions in the future.

Abstract
OBJECTIVES To study the degree and timing of maternal hyperglycemia following betamethasone therapy in nondiabetic patients and establish a prophylactic dose of insulin. METHODS Forty-five patients receiving betamethasone 12 mg i.m. at 7 AM on two consecutive days were randomized to no insulin (n = 20), low-dose insulin (n = 18), and high-dose insulin (n = 7) protocols. Each treatment group received s.c. insulin at 7 AM on the 2 days of betamethasone therapy (20 units NPH/10 units regular, and 40 units NPH/20 units regular, respectively). Capillary plasma glucose measurements were obtained at fasting and 2 h after meals for 3 days. A multivariate normal regression model was used to estimate and compare mean glucose levels. RESULTS Eighty-five percent of patients who did not receive insulin exhibited hyperglycemia at levels previously associated with fetal acidosis. Significant differences in mean postprandial plasma glucose levels were found between the no-treatment and insulin groups on days 1 and 2. No significant differences were noted between groups on day 3. CONCLUSIONS Transient maternal hyperglycemia occurs in a consistent pattern in nondiabetic patients receiving betamethasone, which can be limited by the concurrent use of insulin. Further studies to assess fetal acidosis in this setting are warranted.

Abstract
The temperature distribution produced in living brain tissue by a radiofrequency, Neuro N-50, hyperthermia probe was measured as a function of probe temperature, heating duration, and distance from the heating probe by a sensor containing five thermocouples for durations up to 2 min. Brain sections were examined to determine the effects of heating at various temperatures. It was found that a simple theoretical conductive heat transfer model predicted the steady-state temperature distributions quite well. At distances up to 7.4 mm from the heating probe, a heating time of 20 s was sufficient to produce about 90% of the temperature rise measured at 120 s. The equilibrium temperature at any distance from the center of the probe was a linear function of the reciprocal of this distance. The time constant for heating was approximately 3 s at 0. 95 mm from the heating probe and about 10 s at 7.4 mm for brain tissue, while these values are about 5-20 s in egg white. For a given probe size, higher probe temperatures increased the size of the region of cell death. According to the heat transfer model, the diameter of the region of tissue that attains a given temperature is proportional to the diameter of the probe. The use of probe temperatures up to 90 degrees C would enable an increase in the volume of the region of cell death, or the use of a smaller diameter probe to produce a lesion of a given size.

Abstract
Vertical transmission of human immunodeficiency virus (HIV) accounts for most new pediatric cases in the United States. With the routine use of zidovudine in the antepartum, intrapartum, and postnatal periods, transmission of HIV from mother to infant has decreased significantly during the past 5 years. Most transmission occurs during labor and delivery, so the effect of mode of delivery recently has been investigated. Several studies support cesarean to further reduce infection in newborns. However, those studies are limited by lack of data on concomitant effects of viral load and effects of combined antiretroviral therapy. There also might be increased operative morbidity in this population. Therefore, we suggest caution in establishing cesarean as a standard for delivery of HIV-infected women.

Abstract
OBJECTIVE To examine the relationship between training in induced abortion during residency and subsequent practice patterns in providing abortion services. STUDY DESIGN An anonymous survey of all obstetrician-gynecologists with admitting privileges at a tertiary care hospital in New England was conducted. Physicians were asked about their residency training experience in performing abortions, current practices and attitudes toward abortion. RESULTS Ninety-two of 110 physicians (84%) completed the questionnaire. Six physicians who received training after residency and two with incomplete information were excluded from the analysis. Forty-four respondents received training specifically in first-trimester abortion, and 42 did not. Physicians who received training were more likely to provide abortion services (49% vs. 21%, P = .01), to ask patients about their plans for continuing pregnancy (65% vs. 41%, P = .007) and to support medical assistance funding for abortion (84% vs. 45%, P = .001) than were physicians who did not receive training during residency. Beliefs were significantly associated with current practice, even after controlling for differences in residency training in abortion. CONCLUSION Differences in practice patterns exist between physicians who receive abortion training and those who do not. Practice patterns are associated with beliefs even after controlling for variations in training.

Abstract
Retinopathy and nephropathy are complications of diabetes mellitus that can affect women of reproductive age. This article focuses on the effect of pregnancy on the risk of progression of microvascular disease, both during gestation and at long-term follow-up. Fortunately, with intensive medical surveillance and appropriate interventions, most women with types 1 and 2 diabetes mellitus can be offered an optimistic prognosis for child bearing.

Abstract
OBJECTIVE To measure platelet activation in normal pregnancy, before and after stimulation with agonists, with a whole blood flow cytometric technique. METHODS In a cross-sectional study, 5 mL of whole blood was collected from healthy volunteers (nine in the first trimester, ten in the second trimester, 35 in the third trimester, and 32 nonpregnant controls). Platelets were treated with an agonist (thrombin or U-46619, a thromboxane A2 analogue) or buffer and were exposed to saturating concentrations of monoclonal antibodies directed against platelet membrane glycoproteins (GPs): 7E3 (fibrinogen receptor GPIIb/IIIa), S12 (alpha granule marker P-selectin), and 6D1 (von Willebrand factor receptor GPIb). Mean fluorescence intensity was determined for 5000 platelets per sample by using a flow cytometer. RESULTS In the absence of agonist, no significant difference between groups was found in antibody binding. At no stage of pregnancy were circulating activated platelets detected. Platelets from third-trimester subjects bound significantly less 7E3 than platelets of controls or of first- or second-trimester subjects after stimulation with high-dose thrombin (P < .05 for all comparisons). Down-regulation of 6D1 on platelets after stimulation with high-dose U-46619 was significantly greater in third-trimester gravidas than in controls or first-trimester subjects (P < .05). CONCLUSION Pregnancy does not increase the percentage of activated platelets in the circulation. Platelet reactivity is altered in the third trimester, as evidenced by decreased antibody binding to fibrinogen receptor epitope and enhanced down-regulation of a von Willebrand factor receptor epitope.

Abstract
Associations between elevated amniotic fluid glucose and insulin levels in the second trimester and the subsequent development of gestational diabetes have been reported. We conducted a case-control study to determine which analyte best predicts future maternal glucose intolerance. Thirty-nine women diagnosed with gestational diabetes (criteria of Carpenter and Coustan, Am. J. Obstet. Gynecol., 144, 768, 1982) who had undergone genetic amniocentesis for advanced maternal age were matched with euglycaemic controls. Glucose and insulin concentrations were determined by analysis of stored amniotic fluid samples. No significant difference was detected between cases and controls for amniotic fluid glucose concentrations. Amniotic fluid insulin concentrations were significantly higher in cases (mean rank 4.44, P < 0.01, using matched rank analysis of variance, where 1 is the lowest and 6 is the highest rank). After conversion to multiples of the median, 20 per cent of women with subsequent gestational diabetes were found to have amniotic fluid glucose levels at or above the 90th centile, while 35 per cent of cases had similarly elevated amniotic fluid insulin levels. We conclude that second-trimester amniotic fluid insulin is a more sensitive predictor of impending glucose intolerance than amniotic fluid glucose, although neither is sufficiently powerful to use alone as a screening test.

Abstract
Our objective was to determine whether the cesarean section rate and amniotic fluid lecithin-sphingomyelin ratio (L/S ratio) associated with fetal trisomy 18 are different from those associated with euploid pregnancies. Forty-nine trisomy 18 pregnancies were identified and their records were reviewed. Of the 22 live-born infants, 15 (68%) were delivered by cesarean section. The overall cesarean section rate for the institution ranged from 19.1% to 22.6%. In five patients with gestational ages between 35 and 38 weeks who had amniocentesis as part of the evaluation of intrauterine growth retardation, the L/S ratios were < or = 1.8. These data confirm that undiagnosed trisomy 18 pregnancies are associated with an increased cesarean section rate. Further, trisomy 18 fetuses appear to have delayed maturation of the L/S ratio. These results reinforce the importance of a karyotypic evaluation of selected pregnancies complicated by intrauterine growth retardation, even in the third trimester, and suggest that the prenatal diagnosis of trisomy 18 is of obstetric importance.

Abstract
OBJECTIVE To examine the predictive value of amniotic fluid (AF) insulin at 14-20 weeks' gestation for subsequent gestational diabetes and macrosomia in unselected gravidas 35 years or older at time of genetic amniocentesis. METHODS We identified 296 pregnancies through stored AF samples from genetic amniocenteses (collected March 1987 through August 1992) in women meeting the following criteria: age 35 years or older, amniocentesis at 14-20 weeks, performance of a 50-g glucose challenge test, and adequate delivery data. RESULTS A modified double-antibody radioimmunoassay reliably measured AF insulin with a detection limit of 0.35 microU/mL. Pregnant women in whom gestational diabetes was later diagnosed had higher median AF insulin levels than women who did not (0.60 versus 0.42 microU/mL, respectively; P = .026). A stepwise logistic regression analysis of gestational age at amniocentesis, maternal second-trimester weight, maternal age, and log AF insulin value on gestational diabetes showed only AF insulin to have a significant association with gestational diabetes (P = .004). Seven of 21 cases of gestational diabetes had AF insulin values exceeding the 95th percentile (1.33 microU/mL) compared with only 14 of 275 women with normal glucose tolerance (P < .001). Amniotic fluid insulin did not predict macrosomia in either nondiabetic or gestational diabetic pregnancies. CONCLUSION Gestational diabetes is associated with increased AF insulin at 14-20 weeks, suggesting augmentation of fetal insulin production in the early fetal period in at least some cases of gestational diabetes.

Abstract
BACKGROUND Alpha-thalassemia is one of the most common genetic disorders in the world and is becoming more common in the United States with the increase in immigration of susceptible populations. This disease has been stated previously to be incompatible with extrauterine life. CASE A Filipino woman with a prior loss due to hemoglobin Bart's underwent prenatal diagnosis that confirmed recurrence in the index pregnancy. Intravascular intrauterine exchange transfusions maintained appropriate fetal growth. A cesarean delivery yielded a 2190-g male infant with minor malformations. The postnatal course was characterized by mild respiratory insufficiency. Postnatal chronic transfusion therapy is underway pending consideration for bone marrow transplantation. CONCLUSION Antenatal diagnosis and therapy of homozygous alpha-thalassemia can prevent the prenatal consequences of hydrops and fetal death. New technologies such as stem cell transplantation may help to avert both prenatal and postnatal consequences.
