Genome-wide association study identifies multiple HLA loci for sarcoidosis susceptibility.

Sarcoidosis is a complex systemic disease. Our study aimed to (1) identify novel alleles associated with sarcoidosis susceptibility; (2) provide an in-depth evaluation of HLA alleles and sarcoidosis susceptibility and (3) integrate genetic and transcription data to identify risk loci that may more directly impact disease pathogenesis. We report a genome-wide association study of 1335 sarcoidosis cases and 1264 controls of European descent (EA) and investigate associated alleles in a study of African Americans (AA: 1487 cases and 1504 controls). The EA and AA cohort was recruited from multiple United States sites. HLA alleles were imputed and tested for association with sarcoidosis susceptibility. Expression quantitative locus and colocalization analysis were performed using a subset of subjects with transcriptome data. Forty-nine SNPs in the HLA region in HLA-DRA, -DRB9, -DRB5, -DQA1 and BRD2 genes were significantly associated with sarcoidosis susceptibility in EA, rs3129888 was also a risk variant for sarcoidosis in AA. Classical HLA alleles DRB1*0101, DQA1*0101 and DQB1*0501, which are highly correlated, were also associated with sarcoidosis. rs3135287 near HLA-DRA was associated with HLA-DRA expression in peripheral blood mononuclear cells and bronchoalveolar lavage from subjects and lung tissue and whole blood from GTEx. We identified six novel SNPs (out of the seven SNPs representing the 49 significant SNPs) and nine HLA alleles associated with sarcoidosis susceptibility in the largest EA population. We also replicated our findings in an AA population. Our study reiterates the potential role of antigen recognition and/or presentation HLA class II genes in sarcoidosis pathogenesis.

Histological assessment of microtia cartilage, a potential source of autograft tissue in ear reconstruction.

Cartilage is a strong and flexible connective tissue that has many forms and functions in our body. While cartilage exhibits some forms of limited repair, for the most part, it is not particularly regenerative. Thus, in situations where patients require cartilage reconstruction, surgeons may use autografts to replace missing or damaged tissue. Cartilage tissues from different regions of the body exhibit histological differences and are in limited supply. Thus, it is important to characterize these differences to determine the most appropriate autograft source. In the case of microtia, a congenital deformity where the pinna is underdeveloped, reconstruction commonly utilizes cartilage sourced from a patient's own costal cartilage. This presents a potential morbidity risk. In this study, we evaluate the histological characteristics of microtia cartilage compared with normal auricular and costal cartilage obtained from human patients undergoing surgical resection. Histochemistry was used to evaluate cellularity, lipid content, and ECM content. Using a Bayesian statistical approach, we determined that while costal cartilage is the standard tissue donor, the microanatomy of microtia cartilage more closely reflects normal auricular cartilage than costal cartilage. Therefore, microtia cartilage may serve as an additional reservoir for cartilage during reconstruction.

Providing doula support to publicly insured women in central Texas: A financial cost-benefit analysis.

BACKGROUND: Disparities in birth outcomes continue to exist in the United States, particularly for low-income, publicly insured women. Doula support has been shown to be a cost-effective intervention in predominantly middle-to-upper income White populations, and across all publicly insured women at the state level. This analysis extends previous studies by providing an estimate of benefits that incorporates variations in averted outcomes by race and ethnicity in the context of one region in Texas. The objectives of this study were to determine (1) whether the financial value of benefits provided by doula support exceeds the costs of delivering it; (2) whether the cost-benefit ratio differs by race and ethnicity; and (3) how different doula reimbursement levels affect the cost-benefit results with respect to pregnant people covered by Medicaid in central Texas. METHODS: We conducted a forward-looking cost-benefit analysis using secondary data carried out over a short-term time horizon taking a public payer perspective. We focused on a narrow set of health outcomes (preterm delivery and cesarean delivery) that was relatively straightforward to monetize. The current, usual care state was used as the comparison condition. RESULTS: Providing pregnant people covered by Texas Medicaid with access to doulas during their pregnancies was cost-beneficial (benefit-to-cost ratio: 1.15) in the base model, and 65.7% of the time in probabilistic sensitivity analyses covering a feasible range of parameters. The intervention is most cost-beneficial for Black women. Reimbursing doulas at $869 per client or more yielded costs that were greater than benefits, holding other parameters constant. CONCLUSIONS: Expanding Medicaid pregnancy-related coverage to include doula services would be cost-beneficial and improve health equity in Texas.

Qualitative Insights Into Enhancing Neonatal Resuscitation in Post-Pandemic Vietnam: A Stakeholder Perspective on the Helping Babies Breathe Program.

BACKGROUND: The neonatal phase is vital for child survival, with a substantial portion of deaths occurring in the first month. Neonatal mortality rates differ significantly between Vietnam (10.52/1000 live births) and the United States (3.27/1000). In response to these challenges, interventions such as the Helping Babies Breathe (HBB) program have emerged, aiming to enhance the quality of care provided during childbirth, and the postpartum period in low-resource settings. PURPOSE: The purpose of this study was to explore stakeholder perceptions of the HBB program in Vietnam postpandemic, aiming to identify requisites for resuming training. METHODS: Utilizing qualitative content analysis, 19 in-person semistructured interviews were conducted with diverse stakeholders in 2 provinces of Central Vietnam. RESULTS: The content analysis revealed following 5 main themes: (1) the pandemic's impact on HBB training; (2) resource needs for scaling up HBB training as the pandemic abates; (3) participants' perceptions of the pandemic's effect on HBB skills and knowledge; (4) the pandemic's influence on a skilled neonatal resuscitation workforce; and (5) future prospects and challenges for HBB training in a postpandemic era. IMPLICATIONS FOR PRACTICE AND RESEARCH: This research highlights the importance of sustainable post-HBB training competencies, including skill assessment, innovative knowledge retention strategies, community-based initiatives, and evidence-based interventions for improved healthcare decision-making and patient outcomes. Healthcare institutions should prioritize skill assessments, refresher training, and collaborative efforts among hospitals, authorities, non-government organizations, and community organizations for evidence-based education and HBB implementation.

Pathologic Criteria for the Diagnosis of Usual Interstitial Pneumonia vs Fibrotic Hypersensitivity Pneumonitis in Transbronchial Cryobiopsies.

Transbronchial cryobiopsy (TBCB) is increasingly used for the diagnosis of fibrosing interstitial pneumonias, but there are few detailed descriptions of the pathologic findings in such cases. It has been proposed that a combination of patchy fibrosis and fibroblast foci with an absence of alternative features is diagnostic of usual interstitial pneumonia (UIP; ie, idiopathic pulmonary fibrosis [IPF]) in TBCB. In this study, we reviewed 121 TBCB in which a diagnosis of fibrotic hypersensitivity pneumonitis (FHP; n = 83) or IPF (n = 38) was made by multidisciplinary discussion and evaluated a range of pathologic features. Patchy fibrosis was found in 65 of 83 (78%) biopsies from FHP and 32of 38 (84%) biopsies from UIP/IPF cases. Fibroblast foci were present in 47 of 83 (57%) FHP and 27 of 38 (71%) UIP/IPF cases. Fibroblast foci/patchy fibrosis combined did not favor either diagnosis. Architectural distortion was seen in 54 of 83 (65%) FHP and 32 of 38 (84%) UIP/IPF cases (odds ratio [OR] for FHP, 0.35; P = .036) and honeycombing in 18 of 83 (22%) and 17 of 38 (45%), respectively (OR, 0.37; P = .014). Airspace giant cells/granulomas were present in 13 of 83 (20%) FHP and 1 of 38 (2.6%) UIP/IPF cases (OR for FHP, 6.87; P = .068), and interstitial giant cells/granulomas in 20 of 83 (24%) FHP and 0 of 38 (0%) UIP/IPF (OR, 6.7 x 106; P = .000). We conclude that patchy fibrosis plus fibroblast foci can be found in TBCB from both FHP and UIP/IPF. The complete absence of architectural distortion/honeycombing favors a diagnosis of FHP, as does the presence of airspace or interstitial giant cells/granulomas, but these measures are insensitive, and many cases of FHP cannot be separated from UIP/IPF on TBCB.

Rationalizing the Design of Pluronics-Surfactant Mixed Micelles through Molecular Simulations and Experiments.

Aqueous systems comprising polymers and surfactants are technologically important complex fluids with tunable features dependent on the chemical nature of each constituent, overall composition in mixed systems, and solution conditions. The phase behavior and self-assembly of amphiphilic polymers can be changed drastically in the presence of conventional ionic surfactants and need to be clearly understood. Here, the self-aggregation dynamics of a triblock copolymer (Pluronics L81, EO3PO43EO3) in the presence of three cationic surfactants (with a 12C long alkyl chain but with different structural features), viz., dodecyltrimethylammonium bromide (DTAB), didodecyldimethylammonium bromide (DDAB), and ethanediyl-1,2-bis(dimethyldodecylammonium bromide) (12-2-12), were investigated in an aqueous solution environment. The nanoscale micellar size expressed as hydrodynamic diameter (Dh) of copolymer-surfactant mixed aggregates was evaluated using dynamic light scattering, while the presence of a varied micellar geometry of L81-cationic surfactant mixed micelles were probed using small-angle neutron scattering. The obtained findings were further validated from molecular dynamics (MD) simulations, employing a simple and transferable coarse-grained molecular model based on the MARTINI force field. L81 remained molecularly dissolved up to ∼20 °C but phase separated, forming turbid/translucent dispersion, close to its cloud point (CP) and existed as unstable vesicles. However, it exhibited interesting solution behavior expressed in terms of the blue point (BP) and the double CP in the presence of different surfactants, leading to mixed micellar systems with a triggered morphology transition from unstable vesicles to polymer-rich micelles and cationic surfactant-rich micelles. Such an amendment in the morphology of copolymer nanoaggregates in the presence of cationic surfactants has been well observed from scattering data. This is further rationalized employing the MD approach, which validated the effective interactions between Pluronics-cationic surfactant mixed micelles. Thus, our experimental results integrated with MD yield a deep insight into the nanoscale interactions controlling the micellar aggregation (Pluronics-rich micelles and surfactant-rich micelles) in the investigated mixed system.

Lung transplantation for acute exacerbation of interstitial lung disease.

BACKGROUND: Acute exacerbations of interstitial lung diseases (AE-ILD) have a high mortality rate with no effective medical therapies. Lung transplantation is a potentially life-saving option for patients with AE-ILD, but its role is not well established. The aim of this study is to determine if this therapy during AE-ILD significantly affects post-transplant outcomes in comparison to those transplanted with stable disease. METHODS: We conducted a retrospective study of consecutive patients with AE-ILD admitted to our institution from 2015 to 2018. The comparison group included patients with stable ILD listed for lung transplant during the same period. The primary end-points were in-hospital mortality for patients admitted with AE-ILD and 1-year survival for the transplanted patients. RESULTS: Of 53 patients admitted for AE-ILD, 28 were treated with medical therapy alone and 25 underwent transplantation. All patients with AE-ILD who underwent transplantation survived to hospital discharge, whereas only 43% of the AE-ILD medically treated did. During the same period, 67 patients with stable ILD underwent transplantation. Survival at 1 year for the transplanted patients was not different for the AE-ILD group versus stable ILD group (96% vs 92.5%). The rates of primary graft dysfunction, post-transplant hospital length-of-stay and acute cellular rejection were similar between the groups. CONCLUSION: Patients with ILD transplanted during AE-ILD had no meaningful difference in overall survival, rate of primary graft dysfunction or acute rejection compared with those transplanted with stable disease. Our results suggest that lung transplantation can be considered as a therapeutic option for selected patients with AE-ILD.

Glucose-induced self-assembly and phase separation in hydrophilic triblock copolymers and the governing mechanism.

Poly(ethylene oxide, EO)-poly(propylene oxide, PO)-poly(ethylene oxide, EO)-based triblock copolymers (BCPs) with 80% hydrophilicity stay molecularly dissolved as Gaussian chains at ambient temperature, even at fairly high concentrations (>5 %w/v). This study presents the plausible micellization behaviour of such very-hydrophilic Pluronics® - F38, F68, F88, F98, and F108 - incited upon the addition of glucose at low concentrations and temperatures. The outcomes obtained from phase behaviour and scattering studies are described. At temperatures near to ambient temperature, these BCPs form micelles with a central core made of a PO block, surrounded by a corona of highly hydrated EO chains. The phase transitions in these hydrophilic Pluronics® in the presence of glucose are demonstrated via the dehydration of the copolymer coil, leading to a decrease in the I1/I3 ratio, as determined using fluorescence spectroscopy. The temperature-dependent cloud point (CP) showed a marked decrease with an increase in the PO molecular weight and also in the presence of glucose. The change in solution relative viscosity (ηrel) caused by glucose is due to the enhanced dehydration of the EO block of the BCP amphiphile. Dynamic light scattering (DLS) and small-angle neutron scattering (SANS) investigations suggested that the dimensions of the hydrophobic core increase during the dehydration of the EO-PO blocks upon a temperature increase or after adding varying concentrations of glucose, thereby resulting in a micellar shape transition. It has been observed that added glucose influences the phase behaviour of BCPs in an analogous way to the influence of temperature. Also, plausible interactions between the EO-PO blocks and glucose were suggested based on the evaluated optimized descriptors obtained from a computational simulation approach. In addition, the core-shell blended micelles obtained using these BCPs are successfully utilized for drug (curcumin, Cur) solubilization based on the observed peak intensities from UV-visible spectroscopy. The loading of Cur into glucose-containing and glucose-free hydrophilic Pluronic® micelles shows how the radius of the micellar core (Rc) increases in the presence of glucose, thereby indicating Cur solubility enhancement for the Pluronic® micelles. Various kinetics models were employed, demonstrating a drug release profile that enables this approach to be used as an ideal platform for drug delivery.

Prevalence and Characteristics of Hyperthyroidism Among Patients With Sarcoidosis in the United States.

OBJECTIVE: We aimed to determine the prevalence and clinical characteristics of self-reported hyperthyroidism in patients with sarcoidosis. METHODS: A national registry-based study investigating 3836 respondents to the Sarcoidosis Advanced Registry for Cures questionnaire in the period between June 2014 and August 2019 was conducted. This registry is generated from a web-based questionnaire that is self-reported by patients with sarcoidosis. We compared patients with sarcoidosis who had hyperthyroidism with those who did not. We used multivariate logistic regression analysis to study the association between hyperthyroidism and different cardiac manifestations in patients with sarcoidosis. RESULTS: Three percent of the study respondents self-reported having hyperthyroidism and were generally middle-aged Caucasian women. Compared with patients without hyperthyroidism, patients with hyperthyroidism had more sarcoidosis-related comorbidities (59% vs 43%, P = .001) and more steroid-related comorbidities (56% vs 44%, P = .01), but there was no difference in the sarcoidosis-specific treatments they received, which included corticosteroids. Patients with hyperthyroidism reported sarcoidosis involvement of the heart (26.6% vs 14.9%, P = .005), kidneys (14.9% vs 8%, P = .033) and sinuses (17.7% vs 10.2%, P = .030) more frequently. Cardiac manifestations that were more frequently reported in patients with hyperthyroidism included atrial arrhythmias (11.3% vs 6.3%, P = .046), ventricular arrhythmias (17.2% vs 7.5%, P < .001), congestive heart failure (10.4% vs 5%, P = .017), and heart block (9.4% vs 4.7%, P = .036). CONCLUSION: Hyperthyroidism is infrequent in patients with sarcoidosis but is potentially associated with different cardiac manifestations. We suggest considering routine screening for hyperthyroidism in patients with sarcoidosis, especially in those with cardiac involvement. Further studies are needed to investigate the impact of identifying and treating hyperthyroidism in patients with sarcoidosis.

Hypersensitivity Pneumonitis With and Without Autoimmune Features: A Clinical Comparative Analysis.

BACKGROUND: Hypersensitivity pneumonitis (HP) is an interstitial lung disease (ILD) caused by an immunological reaction to repeated inhalational exposure to antigens. The etiology and exact immunopathology are poorly understood. Autoimmunity overlapping with HP has been described but the role of concomitant autoimmunity in the clinical course and outcome of the HP is not clearly established. In this study, we examined patients diagnosed with HP and compare them to patients with concomitant HP and autoimmunity. METHODS: Patients were retrospectively screened from a single-center ILD registry. Patients > 18 years with an established multidisciplinary diagnosis of HP were included in the study. Patients with HP without autoimmune features and patients with HP with autoimmune features (HPAF) were assessed. We compared the demographics, clinical characteristics, treatment, and outcomes between the two groups. We used a Cox proportional hazards model to compare lung transplant-free survival outcomes of patients with HPAF to those with non-HPAF HP patients. RESULTS: Of 73 patients with HP, 43 were diagnosed with HPAF. Patients with HPAF had a higher echocardiographic probability of pulmonary hypertension as compared to non-HPAF HP patients [48.8 vs 23.3%, p = 0.028, Crude odds ratio (cOR) = 3.14]. Symptomatically, those with HPAF reported a higher prevalence of arthritis as compared to non-HPAF HP (20.9 vs 3.3%, p = 0.040, cOR = 7.68). No significant differences between pulmonary function tests, oxygen requirements, mortality, and lung transplantation rates were found between the two groups. There was no statistically significant difference in transplant-free survival (p = 0.836). CONCLUSION: Patients with HPAF had a higher echocardiographic probability of pulmonary hypertension as compared to patients with non-HPAF HP. The clinical characteristics and outcomes did not differ between the two groups and concomitant autoimmunity among the HP group did not portend a poorer prognosis.

Health Burden and Service Utilization in Texas Medicaid Deliveries from the Prenatal Period to 1 Year Postpartum.

OBJECTIVE: To describe health burden and health service utilization from the prenatal period to 1 year postpartum among women with births covered by Texas Medicaid, focusing on the major contributors to maternal mortality after 60 days postpartum in Texas. METHODS: We analyzed diagnoses and health service utilization during the prenatal, early postpartum (5-60 days postpartum), and late postpartum (> 60 days to 1 year postpartum) periods, using administrative medical claims data for women ages 18-44 years with a Medicaid-paid delivery in 2017 residing in selected regions in Texas (n = 49,302). RESULTS: Overall, 12.6% and 17.5% of women had diagnoses of cardiovascular/coronary conditions and substance use disorder, respectively. Mental health conditions affected 30% of women, with anxiety (47.1%) and depression (34.3%) accounting for the greatest proportion of diagnosed mental health conditions. The prevalence of these conditions was higher during the late (19.4%) versus early (9.9%) postpartum period. About 47.8% of women had other chronic health conditions, including obesity, diabetes mellitus, and hypertension. Among women with the selected health conditions, utilization of any health services was higher during the prenatal period compared to early and late postpartum periods (e.g., any mental health service utilization: prenatal period (57.4%) versus early postpartum (26.9%) and late postpartum (25.5%) periods). However, among women with the selected health conditions, there was a high utilization of emergency room services during the late postpartum period [e.g., emergency room service utilization among those with mental health conditions: prenatal period (35.6%); postpartum period: early (5.5%) and late (30.1%)]. CONCLUSIONS FOR PRACTICE: Increasing access to the full range of recommended services during the prenatal period through 1 year postpartum has potential to help improve vulnerable women's birth outcomes.

Infant Mortality and Maternal Risk Factors in Texas: Highlighting Zip Code Variations in 2 At-Risk Counties, 2011-2015.

INTRODUCTION: Stark differences in the infant mortality rate (IMR) exist by geography in Texas. The Healthy Families initiative sought to understand how evidence-informed practices implemented in the community can improve pregnancy-related outcomes in 2 counties in Texas with a high prevalence of maternal chronic conditions. The objective of this study was to examine associations between maternal risk factors and infant deaths to inform strategies to improve outcomes. METHODS: Two counties with high prevalence of maternal chronic conditions were selected as Healthy Families sites: one with lower prenatal care usage than other counties in the state but an IMR lower than Texas, and the other with a higher IMR among minority racial and ethnic groups compared with other women in the county and Texas overall. Cohort-linked birth and infant death records from 2011 through 2015 provided by the Texas Department of State Health Services were analyzed by using logistic regression to examine associations of maternal sociodemographic and pregnancy risk factors with infant death. The data were mapped at the zip code level. Analyses were limited to births to women aged 15 to 49 years who resided in Texas from 2011 through 2015 (n = 1,942,899 births). RESULTS: The Texas IMR was 5.4 per 1,000 live births, compared with 4.6 and 7.5 per 1,000 live births for Hidalgo and Smith counties, respectively. Congenital malformations were the leading cause of infant death in both counties for infants born in 2015, which was similar to Texas overall. In both counties, maternal marital status, education, multiple gestation, and cesarean delivery were significantly associated with infant mortality. Wide zip code-level variations in IMR and maternal risk factors were observed in both counties. CONCLUSION: Variations in IMR and key maternal risk factors observed at the zip code level helped drive local strategies to maximize outreach of services to disproportionately affected communities.

Clinical Characteristics of Sarcoidosis Patients with Self-Reported Lymphoma: A US Nationwide Registry Study.

PURPOSE: Little is known about the association between sarcoidosis and lymphoma. We aim to determine the prevalence of lymphoma in US sarcoidosis patients and compare the clinical characteristics of patients with and without lymphoma. METHODS: Using a national registry-based study investigating 3560 respondents to the Foundation for Sarcoidosis Research Sarcoidosis Advanced Registry for Cures Questionnaire (FSR-SARC) completed between June 2014 and August 2019, we identified patients who reported the diagnosis of lymphoma following sarcoidosis and randomly selected a computer-generated control sample of sarcoidosis patients with no reported lymphoma with a 2:1 ratio. RESULTS: Among 3560 patients with sarcoidosis, 43 (1.2%) reported developing lymphoma following their sarcoidosis diagnosis. Patients with lymphoma were more likely to be diagnosed with sarcoidosis at a younger age (median, IQR) 40 (27-50) vs 45 (34.8-56, p = 0.017) years, were more likely to be African-Americans OR 95% CI 3.9 (1.6-9.6, p = 0.002), and have low annual income (OR 2.7, 1.1-6.4 p = 0.026). The sarcoidosis-lymphoma group were more likely to have salivary gland (16% vs 5%, p = 0.026) (OR 4; 1.1-14.5) and cutaneous (46% vs 23%, p = 0.023) (OR 2.9; 1.1-7.3) sarcoidosis. They also reported more chronic fatigue (42% vs 23%, p = 0.029), chronic pain (37% vs 13%, p = 0.001), and depression (42% vs 22%, p = 0.019). CONCLUSION: The prevalence of lymphoma reported in sarcoidosis patients is higher than the general population which further supports the possible increased risk of lymphoma in sarcoidosis. Diagnosis of sarcoidosis at a younger age, African-American race, cutaneous, and salivary glands sarcoidosis were associated with lymphoma. Sarcoidosis patients who developed lymphoma reported higher disease burden and more non-organ-specific manifestations.

Recent Applications of Virtual Reality for the Management of Pain in Burn and Pediatric Patients.

PURPOSE OF REVIEW: Virtual reality, via integration of immersive visual and auditory modalities, offers an innovative approach to pain management. The purpose of this review is to investigate the clinical application of virutal reality as an adjunct analgesic to standard of care, particularly in pediatric and burn patients. RECENT FINDINGS: Although relatively new, virtual reality has been successfully implemented in a wide range of clinical scenarios for educational, diagnostic, and therapeutic purposes. Most recent literature supports the use of this adjunct analgesic in reducing pain intensity for pediatric and burn patients undergoing acute, painful procedures. This summative review demonstrates the efficacy of virtual reality in altering pain perception by decreasing pain and increasing functionality among pediatric and burn patients. However, large, multi-center randomized controlled trials are still warranted to generalize these findings to more diverse patient demographics and medical scenarios.

Advanced pulmonary sarcoidosis.

PURPOSE OF REVIEW: Mortality in patients with sarcoidosis has primarily been attributed to advanced pulmonary sarcoidosis. This review aims to provide an update on recent clinical studies that help to better phenotype these patients, discuss new treatment options, and suggest areas where additional research is needed. RECENT FINDINGS: Diagnosis and management of advanced pulmonary sarcoidosis has changed as new technologies and treatment options have emerged. Clinical phenotypes of advanced disease have evolved to show overlap in presentation with other interstitial lung diseases. Assessment involves more advanced imaging modalities. New promising treatment options are being studied. Pulmonary rehabilitation and lung transplantation are being utilized to improve health-related quality of life and survival. SUMMARY: Patients with advanced pulmonary fibrosis can have variable clinical, radiographic, histopathologic presentation. Given the poor health-related quality of life and high rates of mortality, medical therapy and pulmonary rehabilitation may benefit these patients. Lung transplantation should be considered in those with end-stage disease.

Maternal comorbidity index and severe maternal morbidity during delivery hospitalizations in Texas, 2011-2014.

BACKGROUND: Severe maternal morbidity (SMM) prevalence was 194.0 per 10 000 deliveries in Texas in 2015. Chronic, behavioral, and pregnancy-induced conditions, as captured by a maternal comorbidity index, increase the risk for delivery-related morbidity and mortality. The objective of the study was to examine the association between maternal comorbidity index and SMM among delivery hospitalizations in Texas. METHODS: Delivery-related hospitalizations among Texan women aged 15-49 years were identified using the 2011-2014 Texas all-payer inpatient hospitalization public use data files (n = 1 434 441). The primary outcome of interest was SMM, based on the Alliance for Innovation on Maternal Health's coding scheme. The exposure of interest was a maternal comorbidity index. Multivariable logistic regression model was used to examine the association between maternal comorbidity index and SMM. RESULTS: SMM prevalence remained consistent between 2011 and 2014 (196.0-197.0 per 10 000 deliveries, P > .05; n = 1 434 441). Nearly 40% of delivery-related hospitalizations had a maternal comorbidity index of at least 1, and the proportion of deliveries in the highest risk category of comorbidity index (≥5) increased by 12.0% from 2011 to 2014. SMM prevalence was highest among the youngest and oldest age groups. With each unit increase in maternal comorbidity index, the odds of SMM increase was 1.43 (95% CI 1.42-1.43). CONCLUSIONS: Maternal comorbidity index is associated with SMM; however, the low predictive power of the model suggests that other, unmeasured factors may influence SMM in Texas. These findings highlight a need to understand broader contextual factors (practitioner, facility, systems of care, and community) that may be associated with SMM to reduce maternal morbidity and mortality in Texas.

Adjunctive benefit of a xenogenic collagen matrix associated with coronally advanced flap for the treatment of multiple gingival recessions: A superiority, assessor-blind, randomized clinical trial.

AIM: To evaluate the superiority of coronally advanced flaps (CAFs) when used in combination with a xenogeneic collagen matrix (CMX) for root coverage of multiple adjacent gingival recessions. MATERIALS AND METHODS: Participants with at least 2 upper adjacent teeth exhibiting gingival recession depth ≥2 mm were recruited and randomized to CAF with (test) or without (control) CMX, respectively. Mean and complete root coverage, amount of keratinized tissue (KTw), gingival thickness (GThick) and patient-reported outcomes (PROMs) were recorded at baseline, 3, 6 and 12 months. RESULTS: Twenty-four patients providing 61 gingival recessions were analysed. After 1 year, gingival recession depth decreased from 2.3 ± 0.7 to 0.3 ± 0.4 mm in the CAF + CMX group (2.0 ± 0.8 mm meanRC) and from 2.6 ± 1.0 to 0.6 ± 0.3 mm in the control group (2.0 ± 1.1 mm meanRC). No difference was observed between the two groups (p = 0.2023). Nineteen (63%) of the test and 16 (52%) of control defects showed complete root coverage (p = 0.4919). GThick greatly increased in the test group (0.5 mm; 0.2-0.8 mm, 95% CI; p = 0.0057). No difference between the two groups was observed for KTw (p = 0.5668) and PROMs. CONCLUSION: At 1 year, CAF + CMX provided similar root coverage to CAF alone, but a significant increase in gingival thickness.

Maternal risk factor index and cesarean delivery among women with nulliparous, term, singleton, vertex deliveries, Texas, 2015.

BACKGROUND: Cesarean delivery accounts for over one-third of the ~400 000 annual births in Texas, with first-time cesarean accounting for 20% of the overall cesareans. We examined associations of maternal medical comorbidities with cesarean delivery among nulliparous, term, singleton, vertex (NTSV) deliveries in Texas. METHODS: Nulliparous, term, singleton, vertex deliveries to women aged 15-49 years were identified using the 2015 Texas birth file (Center for Health Statistics, Texas Department of State Health Services). A risk factor index was constructed (score range 0-4), including preexisting/gestational diabetes mellitus, preexisting/gestational hypertension/eclampsia, infertility treatment, smoking during pregnancy, and prepregnancy overweight/obesity, and categorized as 0, 1, 2, and 3+ based on the number of risk factors present. Multivariable logistic regression analyses were conducted to examine associations between the categorized risk factor index and cesarean delivery, overall and by maternal race and ethnicity. RESULTS: Among the 114 535 NTSV deliveries in Texas in 2015, 27.2% were by cesarean. The most prevalent maternal risk among all deliveries was prepregnancy overweight/obesity (42.4%). The odds of cesarean delivery increased significantly with increasing number of risk factors [one risk factor: 1.72 (95% CI 1.67-1.78); two risk factors: 2.58 (95% CI 2.46-2.71); and three or more risk factors: 3.91 (95% CI 3.45-4.44)]. DISCUSSION: In Texas in 2015, nearly half of NTSV deliveries had at least one maternal risk factor and the odds of cesarean delivery were significantly elevated for women with a higher risk index score. The findings from this study highlight the need for intervening during the preconception and interconception period as intrapartum care practices have an important influence on birth outcomes.

Immediate Postpartum Long-Acting Reversible Contraception Programs in Texas Hospitals Following Changes to Medicaid Reimbursement Policy.

OBJECTIVES: Provision of long-acting reversible contraception (LARC) after delivery and prior to discharge is safe and advantageous, yet few Texas hospitals offer this service. Our study describes experiences of Texas hospitals that implemented immediate postpartum LARC (IPLARC) programs, in order to inform the development of other IPLARC programs and guide future research on system-level barriers to broader adoption. METHODS: Eight Texas hospitals that had implemented an IPLARC program were identified, and six agreed to participate in the study. Interviews with 19 key hospital staff covered (1) factors that led the development of an IPLARC program; (2) billing, pharmacy, and administrative operations related to implementation; (3) patient demand and readiness; (4) the consent process; (5) staff training; and (6) hospital plans for monitoring and evaluation of IPLARC services. RESULTS: Most hospitals in this study primarily served Medicaid and un- or under-insured populations. Participants from all six hospitals perceived high levels of patient demand for IPLARC and provider interest in providing this service. The major challenges were related to financing IPLARC programs. Participants from half of the hospitals reported that leadership had concerns about financial viability of providing IPLARC. The hospitals with the longest-running IPLARC programs were safety net hospitals with family planning training programs. CONCLUSIONS FOR PRACTICE: We found that hospitals with IPLARC programs all had strong support from both providers and hospital leadership and had funding sources to offset costs that were not reimbursed. Strategies to reduce the financial risks related to IPLARC provision could provide the impetus for new programs to launch and support their sustainability.
