Use of the WHO partograph and Zhang’s guideline for labor and delivery in China: implications for clinical practice

BackgroundThere is an unmet need for a large comprehensive population-based dataset documenting national birthing trends in China and a partograph specifically tailored to Chinese women. This study assessed the impact of using the World Health Organization (WHO) partograph or Zhang’s guideline to manage labor and delivery in China and inform the development of a partograph that specifically aligns with the progression of labor in Chinese women.MethodsThis retrospective analysis included low-risk nulliparous women with a singleton, full-term fetus in cephalic presentation entering spontaneous labor at a specialized obstetric hospital in China between January 2010 and June 2022. Pregnant women were managed according to the WHO partograph (January 2010-August 2014, n = 31,286) or Zhang’s guideline (September 2014-June 2022, n = 49,821).ResultsRates of assisted reproduction (4.57% vs. 1.05%; p < 0.0001) and hypertension (7.44% vs. 6.71%; p < 0.0001) were significantly higher for pregnant women managed according to Zhang’s guideline compared to the WHO partograph. Rates of labor intervention (35.31% vs. 13.95%; p < 0.0001), including induction of labor by oxytocin, artificial rupture of membranes, lateral episiotomy and conversion to cesarean section (all, p < 0.0001), were significantly higher for pregnant women managed according to the WHO partograph. Rates of forceps assisted vaginal deliveries (12.67% vs. 6.42%; p < 0.0001) and postpartum hemorrhage (10.9% vs. 6.2%; p < 0.0001) were significantly higher, and birth asphyxia (0.15% vs. 0.09%; p = 0.02) was significantly lower, for pregnant women managed according to Zhang’s guideline.ConclusionsThis study provides valuable insights into the utilization of the WHO partograph and Zhang’s guideline in managing labor and delivery among Chinese women. Findings indicate that women managed according to Zhang’s guideline had higher rates of assisted reproduction and hypertension, suggesting a potentially different demographic profile or underlying health conditions compared to women managed according to the WHO partograph. Notably, the use of the WHO partograph was linked to a significant increase in labor interventions, while Zhang’s guideline resulted in higher rates of forceps-assisted vaginal deliveries and postpartum hemorrhage, yet interestingly, a lower incidence of birth asphyxia. These contrasting outcomes underscore the importance of aligning labor management tools with the specific needs and progression of labor in Chinese women. The results advocate for a tailored partograph that could better reflect the unique characteristics of Chinese women and optimize decision making and maternal and neonatal outcomes.

Impact of the COVID-19 pandemic on breast cancer surgeries in a Canadian population.

The COVID-19 pandemic significantly impacted breast cancer (BC) surgeries. Most studies showing reduced BC surgical volumes during the pandemic are from single institutions, few have described volume changes in different types of surgical procedures. This study aimed to assess the impact of the pandemic on BC surgery volumes and types at a population level. Patients diagnosed with BC between January 1, 2018, and June 25, 2022, in Ontario, Canada, were analysed from population-based datasets. Time periods were defined as pre-pandemic (Jan 2018-Mar 2020), immediate pandemic (Mar-Jun 2020), and peri-pandemic (Jun 2020-Jun 2022). Weekly BC surgery volume and type (lumpectomy, mastectomy, or mastectomy with immediate reconstruction) were evaluated using segmented negative binomial regression models. Among 44 226 patients, 50 440 surgeries were performed. Weekly BC surgeries decreased by 16.9% during the immediate pandemic compared to pre-pandemic levels (180.5 vs. 217.1; p = 0.03). Surgical volumes recovered to pre-pandemic levels by June 2021. Mastectomies represented a higher proportion of BC surgeries during the pandemic (31.1% pre, 36.3% immediate, 32.4% peri-pandemic; p < 0.01). The proportion of mastectomies with immediate reconstruction remained stable during the immediate pandemic but increased in the peri-pandemic (20.1% vs. 17%; p < 0.01). There was a significant reduction in all BC surgeries during the pandemic. Mastectomies accounted for a higher proportion of BC surgeries in the pandemic period however access to reconstruction was maintained. Surgical volumes recovered within a year despite ongoing pandemic hospitalizations. Future studies are needed to explore the pandemic's long-term impact on BC care.

Polygenic Risk Scores and Hearing Loss Phenotypes in Children

Monogenic causes of childhood hearing loss are well established, as are polygenic risk contributions to age-related hearing loss. However, an untested possibility is that polygenic risk scores (PRS) also contribute to childhood hearing loss of all severities, alongside environmental and/or monogenic causes. To examine the association between a PRS for adult hearing loss and childhood hearing loss phenotypes. This cross-sectional study used a unique population-based dataset spanning normal hearing to profound loss, combining 2 contemporaneous population cohorts in Australia. This included the Child Health CheckPoint, a national population-based cross-sectional study nested within the Longitudinal Study of Australian Children, and the Victorian Childhood Hearing Longitudinal Databank (VicCHILD), a statewide population-based longitudinal data bank open to every child with congenital hearing loss in Victoria, Australia. The analysis took place from March to August 2023. Genotype data were generated from saliva- or blood-derived DNA using global single-nucleotide variations arrays. Based on genotype data, PRS was computed using published UK Biobank genome-wide association study results for self-reported hearing difficulty in individuals aged 40 to 69 years. Hearing outcomes were classified by laterality (bilateral, unilateral), severity (mild, moderate, severe or worse) and types (sensorineural, conductive, mixed, auditory neuropathy, atresia). Analyses included multinominal logistic regressions of PRS with hearing outcomes. Overall, 1488 CheckPoint study children (49.8% boys, aged 11-12 years) and 527 VicCHILD study children (55.2% boys, aged 0-13 years) with hearing and genotype data were included. A 1-SD increment in PRS was associated with higher odds of mild (odds ratio [OR], 1.3; 95% CI, 1.0-1.6), moderate (OR, 5.1; 95% CI, 3.2-8.1), and severe or worse (OR, 5.3; 95% CI, 3.9-7.3) unilateral hearing loss compared with normal hearing. Similarly, the PRS was associated with increased odds of mild, moderate, and severe or worse bilateral hearing loss (per-SD ORs, 3.9-6.6) and all hearing loss types (per-SD ORs, 8.5-10.6). In this cross-sectional study, a PRS initially developed for adult hearing difficulty was associated with wide-ranging childhood hearing loss phenotypes, partly explaining hearing phenotype variations despite shared genetic and environmental factors (eg, preterm birth). Large-scale studies with objectively defined hearing phenotypes are crucial for refining PRS and predicting high-risk children.

Variability in invasive bacterial infection proportions among febrile infants aged 8-90 days using administrative data

ObjectiveDespite decades of research, knowledge is limited regarding sociodemographic risk factors (e.g., sex, rural/urban residence) for invasive bacterial infections (IBIs; bacteremia, bacterial meningitis) in young febrile infants and outcomes of current management strategies. Population-based administrative datasets can provide epidemiological insights not possible with clinical data but are limited because diagnosis codes alone may not accurately reflect culture-positive bacteremia or meningitis infections. Thus, using different IBI case definitions, we report IBI and missed IBI proportions in a population of febrile infants aged 8-90 days. MethodsFor this cross-sectional study, we used New York State’s all-payer database to identify healthy, full-term infants with fever aged 8-90 days evaluated in emergency departments from 2012-2023. We defined IBIs and missed IBIs using previously published diagnosis codes and then restricted original case definitions to inpatient encounters with variable lengths-of-stay. For each approach, we calculated total and age-stratified IBI and missed IBI proportions and used chi square statistics to compare proportions within and across age groups. ResultsOf 67,115 infants who met inclusion criteria (15,191 (23%) aged 8-28 days), total IBI and missed IBI proportions varied from 11.5-32.3/1,000 febrile infants and 4.2-8.0/100 IBIs, respectively. Although IBI proportions decreased significantly with advancing age, missed IBI proportions significantly increased. ConclusionsIBI and missed IBI proportions varied widely by case definition. Missed IBI proportions increased with advancing age in a step-wise fashion regardless of case definition. Validation studies are needed to compare IBI diagnosis codes with culture results to understand the accuracy of identifying IBIs with administrative data.

XCT as a Predictor for Survival in a Population-Based Cohort of Head and Neck Squamous Cell Carcinoma.

xCT, also known as SLC7A11 (solute carrier Family 7 Member 11), is a cystine/glutamate antiporter protein that mediates regulated cell death and antioxidant defense. The aim of this study was to investigate the effect of xCT on the outcome of patients diagnosed with new head and neck squamous cell carcinoma (HNSCC). This retrospective cohort study utilized a population-based dataset, comprising all patients (n = 1033) diagnosed with new HNSCC during 2005-2015 in a population of 697,000 people. All patients (n = 585) with a tumor tissue sample available for immunohistochemical (IHC) staining were included. The follow-up rates were 97% and 81% at 3 and 5 years, respectively. Also, the specificity of the anti-xCT antibody was validated. The expression level and prognostic significance of xCT were strongly dependent on tumor location. In oropharyngeal squamous cell carcinoma (OPSCC) patients, xCT expression was a significant prognostic factor for 5-year overall survival (OAS) (HR: 2.71; 95% CI 1.67-4.39; p < 0.001), disease-specific survival (DSS) (HR: 2.58; 95% CI 1.47-4.54; p = 0.001), and disease-free survival (DFS) (HR: 2.69; 95% CI 1.55-4.64; p < 0.001). Five-year survival rates for OPSCC patients with high and low levels of xCT were OAS 34% versus 62%; DSS 51% versus 73%; DFS 43% versus 73%, respectively. According to a multivariate model adjusted for age, T-class, nodal positivity, and tobacco consumption, xCT was an independent prognostic factor for 3-year survival, in which it outperformed p16 IHC. Similar associations were not observed in squamous cell carcinomas of oral cavity or larynx. Regarding treatment modalities, xCT was most predictive in HNSCC patients who received radiotherapy. High xCT expression was associated with poor prognosis in OPSCC. Our findings suggest that joint analysis of xCT and p16 may add significant value in OPSCC treatment stratification.

A Longitudinal Study Investigating Whether Chronic Rhinosinusitis Influences the Subsequent Risk of Developing Dementia.

Background/Objectives: Numerous studies have explored the association between chronic rhinosinusitis (CRS) and cognitive decline. However, whether CRS is an independent risk factor for the development of dementia remains unclear. Thus, this retrospective cohort study sought to examine the potential association between CRS and increased incidence and risk of dementia by utilizing a representative population-based cohort dataset. Methods: In this study, we identified 2126 patients with CRS aged >55 years and matched them with 8504 controls to assess the incidence and risk of dementia. Results: We found that the incidence of all-cause dementia in CRS patients was 0.125 per 1000 person-years. The risk of developing all-cause dementia events (adjusted hazard ratio [HR] = 1.0, 95% confidence interval = 0.8-1.3) also did not differ significantly between the control group and the CRS group, irrespective of the CRS phenotype. Subgroup analysis also showed no increased adjusted HR for developing Alzheimer's disease (0.9, 0.7-1.2), Parkinson's disease (0.9, 0.5-1.4), and other types of dementia (1.0, 0.7-1.4) in the CRS group compared to the control group. Conclusions: Therefore, the present study demonstrated that patients over 55 years of age with CRS did not exhibit an increased incidence or risk of dementia compared to individuals without CRS.

Do mandatory waiting periods for abortion increase intimate partner violence?

Abortion restrictions affect access to reproductive health care. Research has demonstrated that abortion restrictions (policies that restrict access to abortion services or cause abortion clinics to close) result in reductions of and delays in abortions. We leverage two population-based datasets to investigate the effects of mandatory waiting periods (MWPs), a restrictive state abortion policy, on the prevalence of intimate partner violence (IPV), one of the most common types of crime and a highly prevalent and costly public health problem, using data from the National Incident-Based Reporting System and Uniform Crime Report - Supplemental Homicide Reports. We hypothesize that MWPs increase the prevalence of IPV through changes in financial strains, negative health consequences, and intra-household power dynamics. Using difference-in-differences, event study, and methods accounting for staggered treatment timing, we find that MWPs are associated with increases in IPV. Our findings are valuable for policymakers in today's post-Dobbs environment.

A German perspective on the impact of socioeconomic status in diffuse large B-cell lymphoma

The prognostic influence of socioeconomic status (SES) on the survival of diffuse large B-cell lymphoma (DLBCL) patients remains controversial. This observational study examines the potential impact of regional SES inequalities on overall survival (OS) among DLBCL patients in Germany. We analyzed data from the German nationwide population-based dataset spanning 2004-2019 sourced from the German Center for Cancer Registry Data (n = 49,465). The primary objective was to assess the 5-year OS among patients with low SES compared to those living in middle and high SES areas. SES was grouped according to quintiles of the German Index of Socioeconomic Deprivation, which summarized nine indicators covering aspects of regional education, employment, and income. DLBCL patients in low SES areas had significantly impaired 5-year OS compared to those in middle and high SES regions (59.2% vs. 61.8% vs. 64.1%, p < 0.0001). Yet, additionally accounting for regional premature mortality removed the impact of SES on survival (Hazard Ratio 0.94, 95% CI 0.87–1.01). Our findings indicate that the prognostic impact of socioeconomic deprivation on long-term survival is not due to variations in diagnosis and treatment of DLBCL itself but rather a higher comorbidity burden.

Reference equations for pulse wave velocity, augmentation index, amplitude of forward and backward wave in a European general adult population

Pulsatile hemodynamics have been shown to be independent predictors of cardiovascular events. The aim of the current study was to describe four pulsatile hemodynamic markers in a large, well-established, population-based cohort and to provide reference equations for sex- and age-based standardization of these measurements. 6828 adult participants from the Austrian LEAD (Lung, hEart, sociAl, boDy) cohort study, who were free from overt cardiovascular disease, non-diabetic based on blood test results, and had no history of pharmacological treatment for hypertension, dyslipidemia, and diabetes, comprised the “reference population”. Carotid-femoral pulse wave velocity (cfPWV), augmentation index (AIx), amplitude of forward wave (Pf), and backward wave (Pb) were described in different age categories for both sexes. Sex-specific reference equations for cfPWV, AIx, Pf, and Pb with age as the predictive variable were created using the Lambda-Mu-Sigma (LMS) method. All four parameters increased with age. CfPWV and Pf were higher in males than females, especially in young and middle-age groups (P < 0.001). AIx was higher in females than males in all age categories (P < 0.001). Pb was also higher in females than males in age groups older than 40 years (P < 0.01). Reference equations for the skewness (Lambda), median (Mu), and coefficient of variation (Sigma) values were determined, enabling the calculation of sex- and age-standardized values (z-scores) for each individual’s pulsatile hemodynamic measurement, and an online application was developed. Reference equations derived from a large population-based dataset constitute a suitable tool for the standardization of pulsatile hemodynamics and for the accurate interpretation of vascular aging.

The usage of anticholinergic medications in a low- and middle-income country: a longitudinal comparison of 2013-15 and 2020-22 datasets.

While the effects of anticholinergic drug use have been increasingly highlighted, trends in anticholinergic use remain poorly understood. To determine the changes in frequency and pattern of anticholinergic drug use within a low- and middle-income country. Comparisons were made between population-based datasets collected from Malaysian residents aged 55years and older in 2013-15 and 2020-22. Anticholinergic exposure was determined using the anticholinergic cognitive burden (ACB) tool. Drugs with ACB were categorised according to the Anatomical Therapeutic Chemical (ATC) classification. A total number of 5707 medications were recorded from the 1616 participants included in the 2013-15 dataset. A total number of6175 medications were recorded from 2733 participants in 2020-22. Two hundred and ninety-three (18.1%) and 280 (10.2%) participants consumed medication with ACB in 2013-15 and 2020-22 respectively. The use of nervous system drugs with ACB had increased (27 (0.47%) versus 39 (0.63%). The use of ACB drugs in the cardiovascular (224 (3.9%) versus 215 (3.4%)) and alimentary tract and metabolism (30 (0.52%) versus 4 (0.06%)) classes had reduced over time. Participants in 2020-22 were significantly less likely than those in 2013-15 to have total ACB = 1 - 2 (odds ratio [95% confidence interval] = 0.473[0.385-0.581]) and ACB 3 (0.251[0.137 - 0.460]) compared to ACB = 0 after adjustment for potential confounders (p < 0.001). Although anticholinergic exposure has decreased over time, the use of medications with anticholinergic effects in the nervous system class has risen. This increase is attributable to antipsychotic use, which is of concern due to potential cardiovascular complications, and deserves further evaluation.

Prediction of depressive symptoms severity based on sleep quality, anxiety, and gray matter volume: a generalizable machine learning approach across three datasets

Depressive symptoms are rising in the general population, but their associated factors are unclear. Although the link between sleep disturbances and depressive symptoms severity (DSS) is reported, the predictive role of sleep on DSS and the impact of anxiety and the brain on their relationship remained obscure. Using three population-based datasets (N=1813), we trained the machine learning models in the primary dataset (N=1101) to assess the predictive role of sleep quality, anxiety problems, and brain structural (and functional) measurements on DSS, then we tested our models' performance in two independent datasets (N=378, N=334) to test the generalizability of our findings. Furthermore, we applied our model to a smaller longitudinal subsample (N=66). In addition, we performed a mediation analysis to identify the role of anxiety and brain measurements on the sleep quality and DSS association. Sleep quality could predict individual DSS (r=0.43, R2=0.18, rMSE=2.73), and adding anxiety, contrary to brain measurements, strengthened its prediction performance (r=0.67, R2=0.45, rMSE=2.25). Importantly, out-of-cohort validations in other cross-sectional datasets and a longitudinal subsample provided robust similar results. Furthermore, anxiety scores, contrary to brain measurements, mediated the association between sleep quality and DSS. Poor sleep quality could predict DSS at the individual subject level across three datasets. Anxiety scores not only increased the predictive model's performance but also mediated the link between sleep quality and DSS.

Primary pyeloplasty for uretero-pelvic obstruction in the USA adult population with or without double-J indwelling ureteral stents. Insurance claims data on contemporary time to removal trends, perioperative complications, health care costs, and re-intervention rates.

Using a large population-based dataset, we primarily sought to compare postoperative complications, health-care expenditures, and re-intervention rates between patients diagnosed with ureteropelvic junction obstruction (UPJO) undergoing stented vs. non-stented pyeloplasty. The secondary objective was to investigate factors that influence the timing of DJ stent removal. Patients ≥18 years old with UPJO treated with primary open or minimally-invasive pyeloplasty were identified using the Merative™ Marketscan® Databases between 2007-2021. Multivariable modeling was implemented to investigate the association between Double-J (DJ) stent placement and post-pyeloplasty complications, hospital costs, and re-intervention rates and the role of the perioperative predictors on time to DJ stent removal. Subgroup analyses stratified by ureteral stenting duration were additionally performed. Out of 4872 patients who underwent primary pyeloplasty, 4154 (85.3%) had DJ placement. Postoperative complications were rare (N.=218, 4.47%) and not associated with ureteral stenting (odds ratio [OR]: 0.78, 95% confidence interval [CI]: 0.55-1.12). The median cost for in-hospital charges was $21,775, with DJ stent placement independently increasing the median aggregate amount (OR: 1.29, 95% CI: 1.09-1.53). Overall, re-interventions were performed in 21.18% of patients, with DJ stenting found to be protective (OR: 0.79, 95% CI: 0.66-0.96). Higher Charlson Comorbidity Index, longer hospital stay, and open surgical approach were independent predictors for prolonged DJ stenting time to removal. Our study suggests that patients undergoing stent-less pyeloplasty did have a higher rate of secondary procedures, but not higher complications when compared to those undergoing stented procedures. Concurrently, the non-stented approach is associated with decreased health-care expenditures, despite the increased rates of secondary procedures.

Investigating common mutations in ATP7B gene and the prevalence of Wilson's disease in the Thai population using population-based genome-wide datasets.

Wilson's disease (WD) is a rare metabolic disorder caused by variations in the ATP7B gene. It usually manifests hepatic, neurologic, and psychiatric symptoms due to excessive copper accumulation. The prevalence of WD and its common variants differ across populations. This study aimed to examine these aspects of WD within the Thai population, where information has been limited. We reviewed ClinVar and the Wilson Disease Mutation Database, organizing variants classified as pathogenic or likely pathogenic in one or both databases as "relaxed" and "strict" lists. Allele frequencies were estimated from genotyping array data (Asian Screening Array: ASA; Illumina Corp, CA) of 6291 Thai subjects, which also underwent genotype imputation. The prevalence of WD in the Thai population was estimated assuming Hardy-Weinberg Equilibrium. The strict list yielded a prevalence of 1/24,128 (carrier frequency=1/78), while the relaxed list yielded a prevalence of 1/9971 (carrier frequency=1/50). The most common WD variants in Thai subjects were c.2333 G > T, c.3443 T > C, and c.813 C > A from the strict list, and c.3316 G > A and c.2605 G > A from the relaxed list. The ASA chip covered approximately 59 and 24% of WD variants from the strict and relaxed lists, respectively. Based on the estimated prevalence, a carrier screening program for WD is not currently required in Thailand. However, as genotyping services become more affordable and accessible, such a program would facilitate early identification, treatment, and prevention of WD.

Healthcare costs attributable to diabetes in pregnancy: A cost of illness study in Tasmania, Australia.

To estimate the direct costs during the prenatal, delivery and postpartum periods in mothers with diabetes in pregnancy, compared to those without. This study used a population-based dataset from 2004 to 2017, including 57,090 people with diabetes and 114,179 people without diabetes in Tasmania, Australia. Based on diagnostic codes, delivery episodes with gestational diabetes mellitus (GDM) were identified and matched with delivery episodes without diabetes in pregnancy. A group of delivery episodes with pre-existing diabetes was identified for comparison. Hospitalisation, emergency department and pathology costs of these groups were calculated and adjusted to 2020-2021 Australian dollars. There were 2774 delivery episodes with GDM, 2774 delivery episodes without diabetes and 237 delivery episodes with pre-existing diabetes identified. Across the 24-month period, the pre-existing diabetes group required the highest costs, totalling $23,536/person. This was followed by the GDM ($13,210/person), and the no diabetes group ($11,167/person). The incremental costs of GDM over the no diabetes group were $890 (95% CI 635; 1160) in the year preceding delivery; $812 (616; 1031) within the delivery period and $341 (110; 582) in the year following delivery (p < 0.05). Within the year preceding delivery, the incremental costs in the prenatal period were $803 (579; 1058) (p < 0.05). Within the year following delivery, the incremental costs in the postpartum period were $137 (55; 238) (p < 0.05). Our results emphasised the importance of proper management of diabetes in pregnancy in the prenatal and postpartum periods and highlighted the significance of screening and preventative strategies for diabetes in pregnancy.

Association of Peripheral Vestibular Disorder with Diabetes: A Population-Based Study.

This study aimed to investigate the association of peripheral vestibular disorders with type 1 and type 2 diabetes using a population-based dataset. The data for this study were obtained from Taiwan's Longitudinal Health Insurance Database 2010. The sample consisted of 150,916 patients who were newly diagnosed with peripheral vestibular disorders as cases and 452,748 propensity-score-matching controls without peripheral vestibular disorders. We utilized multivariate logistic regression models to quantitatively evaluate the association between peripheral vestibular disorders and diabetes while considering factors such as sex, age, geographic location, monthly income, urbanization level of the patient's residence, coronary heart disease, hypertension, and hyperlipidemia. The chi-squared test indicates that diabetes was more common in the peripheral vestibular disorder group compared to controls (20.6% vs. 15.1%, p < 0.001). Of all sampled patients, the adjusted odds ratio for diabetes was 1.597 (95% CI = 1.570~1.623) for those with peripheral vestibular disorders when compared to controls, while patients with Ménière's disease, benign paroxysmal positional vertigo, unilateral vestibulopathy, and other peripheral vestibular disorders had respective adjusted odds ratios of diabetes at 1.566 (95% CI = 1.498~1.638), 1.677 (95% CI = 1.603~1.755), 1.592 (95% CI = 1.504~1.685), and 1.588 (95% CI = l.555~1.621) in comparison to controls. Our research has revealed an association between diabetes and an increased susceptibility to peripheral vestibular disorders.

The association of depression and sleep disorders in patients with type 1 diabetes in Taiwan.

The association between depression and sleep disorders in patients with type 1 diabetes mellitus (T1DM) in Taiwan is underexplored. We used a nationwide population-based dataset to evaluate the association of T1DM with these conditions in Taiwan from 2001 to 2019. Patients with T1DM were identified as cases, and 2 control groups were used for comparison: patients with type 2 diabetes mellitus (T2DM) and nondiabetic patients. Age, sex, date of diagnosis, and multiple comorbidities were included and matched using propensity score matching between cases and controls. The primary outcome of this study was to identify new occurrences of the first diagnosis of depression or sleep disorders. After matching, this study included 27,029 T1DM cases, 54,058 T2DM controls, and 108,116 nondiabetic controls. Patients with T1DM exhibited a 1.55-fold higher risk of developing depression (hazard ratio [HR] 1.55, 95% confidence intervals [CI] 1.48-1.61) and a 1.41-fold higher risk of experiencing sleep disorders (HR 1.41, 95% CI 1.37-1.46) compared to nondiabetic controls. Similarly, patients with T2DM displayed elevated risks of both depression (HR 1.39, 95% CI 1.34-1.43) and sleep disorders (HR 1.40, 95% CI 1.37-1.44) relative to non-diabetic controls. When comparing the T1DM and T2DM groups, T1DM patients demonstrated a slightly higher risk of depression (HR 1.11, 95% CI 1.07-1.16) but no significant difference in the risk of sleep disorders compared to T2DM patients. These results were consistent regardless of different ages or sexes. This study demonstrates a significant association between diabetes mellitus and the risk of depression and sleep disorders in a large cohort of Taiwanese patients.

Sexual Orientation-Specific Policies Are Associated With Prenatal Care Use in the First Trimester Among Sexual Minority Women: Results From a Prospective Cohort Study.

Previous research has shown sexual minority women (SMW) are more likely to report multiple maternal and infant health outcomes compared to heterosexual women and that these outcomes are moderated by the policy environment. Little is known, however, about prenatal care use disparities or the social determinants of prenatal care use for SMW. To examine the relationship between sexual orientation-specific policies that confer legal protections (e.g., hate crime protections, housing discrimination, same-sex marriage) and prenatal care use among women using a prospective, population-based data set. Using the National Longitudinal Study of Adolescent to Adult Health and logistic regression, we link measures of state policies to the use of prenatal care in the first trimester among women who had live births. The use of prospective data allows us to adjust for covariates associated with preconception care use prior to pregnancy (n = 586 singleton births to SMW; n = 4,539 singleton births to heterosexual women). Sexual orientation-specific policies that conferred protections were associated with increased use of prenatal care among pregnancies reported by SMW (OR = 1.86, 95% CI 1.16, 2.96). In fact, in states with zero protections, we found no differences in prenatal care use by sexual minority status; however, in states with two or more protective policies, SMW were more likely to access prenatal care in the first trimester than heterosexual women. There was no relationship between sexual orientation-specific policy environments and prenatal care use among pregnancies reported by heterosexual women. Recent research has documented that SMW are more likely to have adverse perinatal and obstetrical outcomes than their heterosexual peers. These findings suggest that Lesbian/Gay/Bisexual-specific policy protections may facilitate the use of prenatal care among SMW, a potentially important pathway to improve reproductive health among this population.

Population-Based Analysis of Local Therapies for Large (>7 cm) Non-Small Cell Lung Cancer Tumors.

This study evaluated the impact of local treatment modalities in the management of large non-small cell lung cancer (NSCLC) tumors using a nationwide population-based dataset. Patients with NSCLC tumors >7 cm that were cN0-1M0 in the Surveillance, Epidemiology, and End Results (SEER) registry from 2010 to 2015 were stratified by local management strategy (surgery, radiation therapy, no local treatment) and evaluated using Kaplan-Meier survival analyses, Cox proportional-hazard methods, and propensity-matched analysis. A total of 3156 patients were identified, of which 1580 (50.1%) underwent surgical resection, 920 (29.2%) received radiation only, 655 (20.7%) received no local treatment. Overall, the 5-year survival of patients undergoing surgical resection was 40.7%, compared to 14.7% and 5.3% for the radiation only and no local treatment groups, respectively (P < .001). Surgery with or without radiation continued to have an independent association with improved survival in multivariable analysis (HR 0.23, P < .0001). Other factors associated with improved survival included younger age, negative nodal disease, and chemotherapy use. In propensity-matched sub-analyses, 5-year survival remained significantly better after surgery alone compared to radiation alone (38.5% vs. 13.6%, P < .001), while survival after radiation alone was better than no local treatment, though both were largely poor (12.4% vs. 7.5%, P < .001). Survival of patients with large NSCLC managed non-surgically is very poor. Despite the significant long-term survival benefit with surgical intervention, nearly half of the study cohort did not undergo surgery. Patients and clinicians can use these results to estimate specific potential benefits when considering possible treatment strategies for large NSCLC tumors.
