Analysis of the current status of red blood cell transfusion in very preterm infants from Chinese Neonatal Network in 2022

Objective: To analyze the current status of red blood cell transfusion in very preterm infants (VPI) (gestational age at birth <32 weeks) from Chinese Neonatal Network (CHNN) in 2022. Methods: This cross-sectional study was based on the CHNN VPI cohort. It included 6 985 VPI admitted to CHNN 89 participating centers within 24 hours after birth in 2022. VPI with major congenital anomalies or those transferred to non-CHNN centers for treatment or discharged against medical advice were excluded. VPI were categorized based on whether they received red blood cell transfusions, their gestational age at birth, the type of respiratory support received during transfusion, and whether the pre-transfusion hemoglobin levels exceeded the thresholds. General characteristics, red blood cell transfusion rates, number of transfusions, timing of the first transfusion, and pre-transfusion hemoglobin levels were compared among different groups. The incidence of adverse outcomes between the group of VPI who received transfusions above the threshold and those who received transfusions below the threshold were compared. Comparison among different groups was conducted using χ2 tests, Kruskal-Wallis H tests, Mann-Whitney U test, and so on. Trends by gestational age at birth were evaluated by Cochran-Armitage tests and Jonckheere-Terpstra tests for trend. Results: Among the 6 985 VPI, 3 865 cases(55.3%) were male, with a gestational age at birth of 30.0 (28.6, 31.0) weeks and a birth weight of (1 302±321) g. Overall, 3 617 cases (51.8%) received red blood cell transfusion, while 3 368 cases (48.2%) did not. The red blood cell transfusion rate was 51.8% (3 617/6 985), with rates of 77.7% (893/1 150) for those born before 28 weeks gestational age and 46.7% (2 724/5 835) for those born between 28 and 31 weeks gestational age. A total of 9 616 times red blood cell transfusions were administered to 3 617 VPI, with 632 times missing pre-transfusion hemoglobin data, and 8 984 times included in the analysis. Of the red blood cell transfusions, 25.6% (2 459/9 616) were administered when invasive respiratory support was required, 51.3% (4 934/9 616) were receiving non-invasive respiratory support, while 23.1% (2 223/9, 616) were given when no respiratory support was needed. Compared to the non-transfusion group, the red blood cell transfusion group had a higher rate of pregnancy-induced hypertension in mothers, lower rates of born via cesarean section and mother's antenatal steroid administration, smaller gestational age, lower birth weight, a higher proportion of small-for-gestational-age, multiple births, and proportions of Apgar score at the 5th minute after birth ≤3 (all P<0.05). They were also less likely to be female, born in hospital or undergo delayed cord clamping (all P<0.01). Additionally, higher transport risk index of physiologic stability score at admission were observed in the red blood cell transfusion group (P<0.001). The number of red blood cell transfusion was 2 (1, 3) times, with the first transfusion occurring at an age of 18 (8, 29) days, and a pre-transfusion hemoglobin level of 97 (86, 109) g/L. For VPI ≤7 days of age, the pre-transfusion hemoglobin levels for invasive respiratory support, non-invasive respiratory support, or no respiratory support, respectively, with no statistically significant differences between groups (H=5.59, P=0.061). For VPI aged 8 to 21 days and≥22 days, the levels with statistically differences between groups (both P<0.01). Red blood cell transfusions above recommended thresholds were observed in all respiratory support categories at different stages of life, with the highest prevalence in infants aged 8 to 21 days and≥22 days who did not require respiratory support, at 90.1% (264/273) and 91.1%(1 578/1 732), respectively. The rate of necrotizing enterocolitis was higher in the above-threshold group (χ2=10.59,P=0.001), and the duration of hospital stay was longer in the above-threshold group (Z=4.67, P<0.001) compared to the below-threshold group. Conclusions: In 2022, the red blood cell transfusion rate was relatively high among VPI from CHNN. Pre-transfusion hemoglobin levels frequently exceeded recommended transfusion thresholds.

Evolution of HIV Epidemic and Emerging Challenges - China, 1989-2023.

This study aimed to provide a comprehensive analysis of the human immunodeficiency virus (HIV) epidemiological landscape in China through a historical review and current assessment. Data were extracted from China's HIV/AIDS Comprehensive Response Information Management System (CRIMS). Transmission patterns across different phases were visualized using stacked area charts. Geographical correlations between transmission routes were analyzed using scatter plots and Pearson correlation coefficients. The extent and trends of HIV spread among the general population were evaluated using Venn diagrams and Cochran-Armitage tests. The HIV epidemic in China evolved through four distinct phases: injecting drug user (IDU) dominated (1989-1994), former plasma donor (FPD) outbreak (1995-2005), sexual transmission dominance (2006-2014), and general population spread (2015-present). A strong correlation was observed between provinces reporting high numbers of IDU cases and those with elevated heterosexual transmission (r=0.88, P<0.001). Between 2015 and 2023, 393,926 cases were identified among the general population through non-marital and non-commercial heterosexual contact (NMNCHC). The proportion of general population cases among heterosexual transmissions increased significantly from 46.2% to 55.7% (Z=42.7, P<0.001). The significant spread of HIV into the general population necessitates the development of targeted prevention strategies for both high-risk and general populations to address emerging epidemiological challenges.

Relationship Between Breast Density and Ptosis Degree in Direct-to-Implant Breast Reconstruction.

Direct-to-implant breast reconstruction is a popular procedure since breast volume can be acquired immediately. Various evaluations have been utilized to achieve symmetry. We measured the weight and volume of mastectomy specimens and calculated the relationship between breast density and ptosis degree. We conducted a retrospective chart review of patients who had undergone direct-to-implant breast reconstruction. Clinical data from 155 patients were reviewed, and they were classified based on breast density (weight/volume) (Group 1: density < 0.9 g/mL [n=17], Group 2: 0.9 g/mL ≤ density <1.1 g/mL [n=59], and Group 3: density ≥ 1.1 g/mL [n=79]). The relationship between breast density and ptosis degree was analyzed using the Cochran-Armitage test for trend. Adequate suture and anchoring techniques were applied to achieve symmetric breasts. Postoperative outcomes were assessed by measuring the discrepancy in nipple height. A statistically significant relationship was found between higher breast density and a greater degree of ptosis. The outcome showed a significant trend across Group 1, 2 and 3 (p<0.05). In postoperative analysis, the nipple level discrepancy was less than 10 mm as follows: 100% in Group 1, 89.8% in Group 2, and 70.9% in Group 3, showing a progressive decreasing trend from Group 1 to Group 3 (p<0.05). Direct-to-implant breast reconstruction is an attractive technique, offering predictable outcomes based on adequate measurements. The relationship between breast density and the degree of ptosis is a significant indicator in making intraoperative decisions. Breast density is an adjunctive index for achieving patients' expectations of symmetrical breasts. This journal requires that authors assign a level of evidence to each article.

Abstract 4147608: Trends in Mortality and 30-Day Readmission Rates Among Heart Failure Patients Undergoing Cardiac Rehabilitation: A Nationwide Analysis from 2017 to 2020

Background: Heart failure (HF) is a significant public health concern, affecting approximately 6.2 million adults in the United States, with high mortality and readmission rates. Cardiac rehabilitation (CR) programs have been widely recognized as a crucial component of HF management, aiming to improve physical function, reduce symptoms, and enhance quality of life. Despite the established benefits of CR, there is a need to understand the trends in mortality and readmission rates among HF patients participating in these programs. We aim to analyze mortality and 30-day readmission rate trends among heart failure patients undergoing cardiac rehabilitation from 2017 to 2020 using NRD data. Hypothesis: We hypothesize a significant downward trend in mortality rates and significant yearly variation in 30-day readmission rates among heart failure patients undergoing cardiac rehabilitation. Methods: We analyzed NRD data from 2017 to 2020, including patients with ICD-10 codes I50 (heart failure) and Z5189 (cardiac rehabilitation). Trend analyses were performed using Ordinary Least Squares (OLS) regression for mortality rates and the Cochrane-Armitage test for binary data. Multivariate regression adjusted for age, sex, and comorbidities. Statistical analyses were conducted using STATA version 18. Results: From 2017 to 2020, annual mortality rates were 6.9% (95% CI: 0.95% to 12.85%), 5.5% (95% CI: 0.47% to 10.52%), 4.6% (95% CI: -0.51% to 9.68%), and 1.9% (95% CI: -1.90% to 5.74%), respectively. The mean age was 78 years, with 54% were female. OLS regression showed a significant downward trend in mortality (p = 0.025), while the Cochrane-Armitage test did not (p = 0.998). Multivariate regression also indicated a downward trend, though individual predictors were insignificant (p=0.576). For 30-day readmission rates from 2017 to 2020, annual margins were 21.5% (2017), 21.7% (2018), 18.0% (2019), and 34.3% (2020), showing significant yearly variation. Conclusion: Despite the varying range of 30-day readmission within the years of interest, there seems to be a significant downward trend in mortality for heart failure patients who underwent cardiac rehabilitation. Further studies are required to corroborate these findings as understanding CR program outcomes can help identify improvement areas, guide resource allocation, and inform healthcare policy decisions.

Xylazine Positivity in Opioid-Positive Drug Screens on an Inpatient Labor Unit.

Untreated opioid use disorder (OUD) is associated with significant morbidity in pregnancy. Recent reports have highlighted the rise of xylazine in the nonprescribed fentanyl supply. The frequency with which pregnant people with OUD are exposed to xylazine has not been characterized. We sought to describe the rate of xylazine detection in urine drug screens (UDS) from pregnant people admitted to a labor unit. We performed a cross sectional study of all UDS results from an inpatient obstetric unit at an urban tertiary care center from December 2022, when xylazine was added to the detection panel, through July 2023. We perform universal verbal drug screening, with subsequent urine drug screening only performed after a positive verbal screen and consent. The trend of opioid-positive urine drug screens also positive for xylazine from December to July was measured with the Cochran-Armitage test. Of 5662 people admitted to Labor and Delivery during the study period, 138 UDS were sent for 123 unique individuals. Ninety-eight (71%) of UDS were positive for nonprescribed substances. Of positive UDS, 36 (37%) were positive for nonprescribed opioids, and of these, 17 (47.2%) were positive for xylazine among 14 pregnant people. The trend of UDS positive for opioids that were also positive for xylazine increased significantly over time (P = 0.030), from 0% in December 2022 to 100% in July 2023. Over 8 months, xylazine positivity significantly increased in UDSs positive for nonprescribed opioids in an urban Midwestern hospital. These results underscore the critical need to study the impact of xylazine on obstetric outcomes.

Trends in hospitalization for female breast and gynecological cancer in China from 2004 to 2020

Breast and gynecological cancers are common cancers with high mortality and have profound effects on the various physical functions of women. This study assessed trends in the number of hospitalizations, in-hospital mortality, length of stay (LOS), and hospital charges for female breast and gynecological cancer from 2004 to 2020. The data for this study come from the China Health Statistics Yearbook. Time trends of categorical variables were assessed with the Cochran-Armitage Test. The linear model was used to test for the trend of continuous variables. The hospitalizations for breast cancer increased from 15,204 to 276,387 (P for trend < 0.001) and gynecological cancer increased from 12,418 to 214,956 (P for trend < 0.001). The in-hospital mortality rate due to breast cancer decreased from 1.70 to 1.07% (P for trend < 0.001). Hospitalizations for both breast and gynecological cancer increased clearly, whether in urban or rural. The gap between urban and rural has narrowed. The average cost per hospitalization for breast cancer significantly increased. However, the average LOS for breast cancer gradually decreased (from 17.0 to 10.7 days, P for trend < 0.001). The average cost per hospitalization for gynecological cancer increased significantly. However, this steady downward trend was observed in the average LOS for gynecological cancer (from 10.34 to 6.69 days, P for trend = 0.003). The increase in hospitalizations and medical expenses for breast and gynecological cancer should encourage healthcare policymakers and healthcare system stakeholders to develop more cost-effective approaches to women’s cancer management.

Infections and Patient Satisfaction in WALANT Hand Surgery in a Hospital Procedure Room.

Background: Wide-awake hand surgery has allowed many hand procedures to be moved out of the operating room and into minor procedure rooms while increasing efficiency, maintaining safety, and reducing both patient and hospital costs. The goal of this study was to evaluate patient satisfaction and postoperative complications of wide-awake local anesthesia with no tourniquet procedures performed in a community-based hospital procedure room. Methods: A total of 786 patients underwent 948 elective hand procedures in a hospital procedure room. At the conclusion of their surgeries, the patients were surveyed regarding their satisfaction. Following surgery, patients were evaluated for postoperative complications including infections. The trend in postoperative infection rates across 8 age groups was analyzed using a Cochran-Armitage test in R. Results: The overall infection rate was 6.2% (n = 59). All infections were superficial. Carpal tunnel had the highest number of infections (n = 25), followed by trigger finger (n = 8), and the combination trigger finger with carpal tunnel (n = 7). All infections were managed with antibiotics and/or soaks. Three patients did require a return to the operating room for irrigation and debridement. Ninety-nine percent of patients said the procedure room experience was better or the same as going to the dentist, would recommend wide-awake anesthesia to a friend or family member, and would undergo the procedure again. Conclusion: Wide-awake procedures performed in a hospital procedure room have low infection rates with high patient satisfaction.

Trends and patterns in pulmonary arterial hypertension-associated hospital admissions among methamphetamine users: a decade-long study.

Pulmonary arterial hypertension (PAH) is a rare, chronic, progressive form of pulmonary hypertension in which increased arterial pressure causes remodeling of the arterial system and is associated with heart failure. Methamphetamine is a stimulant that has recently become a focus in PAH research, but the recent trends and demographics of this cohort of patients are not known. The study aimed to analyze the overall trends and demographics of PAH patients with and without concurrent methamphetamine usage. The study used the National Inpatient Sample (NIS), Healthcare Cost and Utilization Project (HCUP), and Agency for Healthcare Research and Quality (AHRQ) from 2008 to 2020 to calculate nationally weighted estimates for both conditions by ICD-9 and ICD-10 diagnosis codes. We used several statistical measures, including descriptive statistics with design-based chi-square and t-tests, trend analysis with Cochran-Armitage test, generalized linear models, and other data preprocessing measures. A significant increase was evident in patients with pulmonary arterial hypertension (PAH) and concurrent methamphetamine use (9.2-fold). Most of the hospitalized patients were males (59.16%), aged 41-64 (45.77%), White (68.64%), from the West (53.09%), with Medicaid (50.48%), and with median income <$25,000. The rate of increase over the period was higher for males (11.8-fold), race (not sure which race; please check and modify), aged 41-64 (11.3-fold), and in the South (15.1-fold). An overall adjusted prevalence ratio (PR) for PAH hospitalizations among concurrent methamphetamine users was 32.19 (CI = 31.19-33.22) compared to non-users. With respective reference categories, the significantly higher PR was evident for males, patients aged 41-64, White, with Medicare, median income <$25,000, all regions compared to Northeast, length of hospital stays, and conditions, including chronic pulmonary disease, diabetes, hypertension, obesity, and peripheral vascular disorders. This study reveals a national overall and demographic-specific trend of increasing PAH with concurrent methamphetamine usage and associated factors. The findings may help to understand the current patterns and identify the vulnerable sociodemographic cohorts for further research and to take appropriate policy measures.

Non-medical use of tranquilizers and sedatives by 15-16-year-old adolescents in Estonia, 2003–2019

Abstract Background Non-medical use of prescription drugs has become a global concern in recent decades. This study aimed to explore trends in non-medical tranquilizers and sedatives use (NTSU) among adolescents in Estonia from 2003 to 2019. Methods Utilizing data from the cross-sectional European School Survey Project on Alcohol and Other Drugs (ESPAD) conducted in 2003-2019, study included 15-16-year-old Estonian schoolchildren (n = 11,328; 48.6% boys). Cochran-Armitage test was employed to assess changes in NTSU trends, with statistical significance set at p &amp;lt; 0.05. Prevalence rates and 95% CIs used as outcome measures. Results From 2003 to 2019, the lifetime prevalence of NTSU significantly increased for both genders, with girls consistently showing higher rates. Among boys, NTSU rose from 5.0% (95% CI 3.8-6.5) to 11.3% (95% CI 9.6-13.3), particularly among those reporting NTSU 1-2 times, from 3.0% (95% CI 2.1-4.2) to 8.2% (95% CI 6.7-9.9), p &amp;lt; 0.001. Similarly, for girls, NTSU rose from 12.6% (95% CI 10.7-14.7) to 17.5% (95% CI 15.4-19.7), p &amp;lt; 0.001. There was an increase among girls reporting NTSU 1-2 times from 7.5% (95% CI 6.0-9.2) to 10.6% (95% CI 9.0-12.4), p &amp;lt; 0.001, and those reporting NTSU three or more times, from 5.1% (95% CI 3.9-6.6) to 6.9% (95% CI 5.6-8.4), p = 0.017. Among boys reporting medical tranquilizers and sedatives use (MTSU), NTSU rose from 21.1% (95% CI 13.9 to 30.0) in 2003 to 41.4% (95% CI 32.3 to 50.9) in 2019, p = 0.006. However, there was no statistically significant change in NTSU among girls reporting MTSU, remaining at 44.1% (95% CI 36.0 to 52.4) in 2019, p = 0.951. Conclusions Study reveals a significant increase in lifetime NTSU from 2003 to 2019, with girls consistently showing higher prevalence. Targeted interventions are needed to address adolescent non-medical prescription drug use, particularly among girls. Moreover, substantial NTSU among those reporting MTSU highlights the need to monitor and address non-medical usage in this subgroup. Key messages • Estonian adolescent non-medical tranquilizers and sedatives use surged from 2003 to 2019, particularly among girls, highlighting the need for targeted interventions. • The high prevalence of non-medical tranquilizer and sedative use among those reporting medical tranquilizer and sedative use underscores the necessity for vigilant monitoring.

Nationwide analysis of in-hospital mortality and renal infarction trends following cardiac output assist device placement from 2017 to 2020

Abstract Background Cardiac output assist devices (COAD) have become a crucial therapeutic option for advanced heart failure patients. However, the clinical outcomes and complications associated with cardiac output device placement, especially in relation to renal health, remain a subject of concern. Purpose We aimed to examine temporal trends of in-hospital mortality and renal infarct (RI) among heart failure in patients who underwent placement of cardiac output assist devices, including intra-aortic balloon pumps and impeller-based devices, between 2017 and 2020. Methods The National Inpatient Sample was queried from 2017 to 2020 to identify all adults who underwent COAD using the International Classification of Diseases 10th Revision codes. The Cochran-Armitage test was used to assess the linear trend of in-hospital RI among patients with COAD. Multivariate and univariate regression analysis was conducted to assess the yearly association of COAD with in-hospital mortality and RI with COAD. The Elixhauser comorbidity index was used to adjust for confounders. Linear logistic results are represented as adjusted odds ratios (ORs) with their respective 95% Confidence Intervals (CI). Results Of the 176,225 patients who underwent COAD, 385 (0.2%) experienced RI, predominantly male (72%) with a mean age of 58. Trend analysis showed an upward trend in RI (trend: 0.21%, p &amp;lt; 0.001) associated with COAD from 2017 to 2020. In 2018, 0.19% of patients had RI (OR = 3, 95% CI 2.1-6.1, p &amp;lt; 0.001), 0.23% in 2019 (OR = 4.6, 95% CI 2.5-7, p &amp;lt; 0.001), and 0.29% in 2020 (OR = 3.6, 95% CI 2.3-5.9, p &amp;lt; 0.001), compared to 0.17% in 2017 (OR = 2.3, 95% CI 1.1-4.7) demonstrated in Figure 1. Mortality among RI and COAD patients was 40% in 2017 (OR 3, 95% CI 1.2-8.9, p = 0.04), decreased to 24% in 2018 (OR 1.2, p = 0.69), but increased to 43% in 2019 (OR 3.2, 95% CI 1.2-7.9, p = 0.01) and remained high at 42% in 2020 (OR 2.9, 95% CI 1.3-6.9, p = 0.019) as illustrated in Table 1. Overall, in-hospital mortality was 38% (OR 2.5, 95% CI 1.5-4, p &amp;lt; 0.001). Conclusions Our study identified a rising trend in in-hospital RI rates among patients with cardiac output assist devices from 2017 to 2020, accompanied by a significant risk of in-hospital mortality. Despite these complications occurring in a small percentage of individuals, they highlight the critical need for vigilant monitoring and proactive management in this patient population.Figure 1

Trends in intracardiac thrombus formation in myocardial infarction patients after PCI: a nationwide analysis

Abstract Background Percutaneous coronary interventions (PCI) have become a crucial therapeutic option for myocardial infarction (MI) patients. However, the clinical outcomes and complications associated with PCI, especially in relation to intracardiac thrombus, remain a subject of concern. Purpose We aimed to examine the real-world clinical outcomes and temporal trends of in-hospital mortality and intracardiac thrombus among myocardial infarction patients treated with PCI between 2017 and 2020. Methods The National Inpatient Sample was queried from 2017 to 2020 to identify all adults with myocardial infarction (ST elevation and Non-ST elevation MI) who underwent PCI using the International Classification of Diseases, 10th Revision codes. The Cochran-Armitage test assessed the linear trend of in-hospital intracardiac thrombus and mortality. Multivariable regression analysis was conducted to assess the association of PCI with in-hospital mortality and intracardiac thrombus. The Charlson comorbidity index was used to adjust for confounders. Results are represented as adjusted odds ratios (ORs) with their respective 95% confidence intervals (CIs). Results Of the 1,394,650 patients who underwent PCI, 8,080 (0.58%) experienced intracardiac thrombus, with a mean age of 62, predominantly male (76%). Despite decreasing rates of PCI noted over this 4-year period (Figure 1). There was an upward trend in in-hospital intracardiac thrombus revealed over a 4-year period (trend: 0.54%, p &amp;lt; 0.001). PCI was associated with a yearly increase in intracardiac thrombus in 2018 in 0.54% of patients (OR = 1.36, 95% CI 1.2 to 1.6, p &amp;lt; 0.001). In 2019, 0.56% of patients experienced intracardiac thrombus (OR = 1.4, 95% CI 1.2 to 1.6, p = 0.001); in 2020, 0.72% of patients (OR = 1.8, 95% CI 1.6 to 2.1, p = 0.008), compared to 2017 (0.4%). Mortality rates for PCI and ICT patients were 6% in 2017 (OR 2.2, p &amp;lt; 0.001, 95% CI 1.4-3.2), decreased to 5% in 2018 (OR 1.8, p &amp;lt; 0.004, 95% CI 1.2-2.6) and 4.7% in 2019 (OR 1.6, p &amp;lt; 0.01, 95% CI 1.1-2.4), then rose to 6.6% in 2020 (OR 2, 95% CI 1.4-2.8) (Table 1). Overall, in-hospital mortality was 5.6% (OR = 1.6, 95% CI 1.3 to 1.9, p &amp;lt; 0.001) among patients who had intracardiac thrombus related to PCI. Conclusions Our findings indicate a significant increase in intracardiac thrombus rates among MI patients treated with PCI from 2017 to 2020, accompanied by a considerable risk of in-hospital mortality. These outcomes underscore the critical need for vigilant monitoring and enhanced management approaches in this patient demographic.Figure 1Table 1

Changes in attitudes toward suicide after brief gatekeeper education: Findings from population-based repeated cross-sectional surveys conducted among middle-aged and older adults

Objective This study aimed to investigate changes in attitudes toward suicide following a universal home visitation program that included a brief face-to-face educational session focusing on gatekeeper roles in Japan.Methods Between 2015 and 2017, members of 169 households in an intervention district from a northern Japanese township were invited to attend an educational session during home visits. The participation rate was 72.8%, with 94.5% of the participants aged over 40. Repeated cross-sectional population-based surveys were conducted among adults in the towns in 2015 and 2021. Data from the surveys, focusing on individuals aged 40-79 years and residing in the intervention and matched control districts (where no visits occurred and only information was distributed through leaflets), were used to assess the prevalence of self-reported views toward suicide. The self-reported views encompassed "no substantial thoughts," "inevitable," "shameful," "annoying," "tragic," "must be managed," and "romantic" in addition to personal and perceived stigma, depressive symptoms (assessed using the Kessler Psychological Distress Scale-6), and suicidal ideation. Data were analyzed using generalized linear mixed models. The Cochran-Armitage test was used to analyze linear trends in the proportion of views that exhibited changes.Results Participation rates were 61.8% (n ＝ 357) in 2015 and 52.8% (n ＝ 257) in 2021. The intervention group showed a significant difference in the prevalence of the "inevitable" view between baseline and 4-year follow-up (P ＝ 0.026). Marginal pre-post differences were observed among the two types of stigma; however, the symptoms remained unchanged. A marginally significant difference in the change of the "inevitable" view was observed between the two groups. In the follow-up, more knowledgeable respondents in the intervention group were less likely to view suicide as "inevitable," a trend not seen in the control group.Conclusions The universal home visitation program, including a face-to-face session focusing on the gatekeeper role, was associated with a decreased prevalence of the "inevitable" attitude between the baseline and 4-year follow-up among community-dwelling adults aged 40-79. This suggests that face-to-face interactions with healthcare professionals can reduce the tendency to condone suicide among middle-aged and older adults in community settings.

Trends in general surgeon operative practice patterns in a modern cohort

IntroductionAnalyzing general surgeons’ operative case mix can provide an update on contemporary practice patterns and inform pragmatic residency training. MethodsWe performed a retrospective cohort study of general surgeons in Florida, Iowa, and Maryland, 2016–2020. Cases were identified using billing codes. The Cochran-Armitage test of trends was used to evaluate the proportion of practice devoted to specific case types and operative setting over time. ResultsGeneral surgeons (n ​= ​1300) performed 1,287,745 cases. The mean (±SD) annual volume per surgeon for all procedures was 356 (±250), with 198 (±152) general surgery operations, 57 (±142) endoscopic procedures, and 101 (±109) other cases. On average, surgeons operated on 7.1 (±2.6) different organ systems. Trends toward a lower proportion of general surgery operations, and a greater proportion of subspecialty procedures and surgery in the outpatient setting over time were demonstrated (p ​< ​0.001). ConclusionThe practice pattern of the general surgeon continues to be heterogeneous, reflecting the persistent need for a broad training paradigm that permits specialization.

6536 National Trends in Prevalence of Prediabetes and Diabetes Among Women With Low Bone Mineral Density: 2009-2018

Abstract Disclosure: A. Atri: None. C. Anastasopoulou: None. Introduction: In recent years, bone fragility has emerged as a complication of prediabetes (preDM) and diabetes mellitus (DM), resulting in reduced bone mass and increased fracture risk, and is an important, though under-studied risk factor for osteoporosis. However, the converse relationship, trends in prevalence of preDM and DM in women with low bone mineral density (BMD) in the United States, are not well established. Methods: We used data from the National Health and Nutrition Examination Survey (NHANES) for the years 2009-10, 2013–14 and 2017–18 to include U.S. women aged ≥ 50 years with T-score ≤ -1. Osteoporosis assessment in NHANES was not completed in 2011–12 and 2015–16, and therefore not included in the analysis. Osteopenia and osteoporosis were defined by a femoral neck BMD ≤1 to 2.5, and ≤2.5 standard deviations (SDs) below the BMD of a young female adult mean (T-score). Femur neck BMD was measured by dual energy x-ray absorptiometry (DEXA). PreDM and DM were defined using HbA1c values of 5.7 - 6.4% and ≥ 6.5% respectively. Participants with missing HbA1c and BMD data were excluded. Descriptive statistics were used for comparing means and medians. The Cochran-Armitage test was utilized for trend analysis. Results: In this nationally representative sample of US women with low BMD, the median (IQR) T-score at femoral neck worsened from -1.74 (-1.4 to -2.17) in 2009-10 to -1.87 (-1.43 to -2.32) in 2017-18 (trend p = 0.001). Similarly, the prevalence of osteoporosis increased from 13.7% to 16.9% (trend p = 0.001). Overall, in this cohort, the national prevalence of both preDM and DM decreased from 40% to 32.9% and 9.6% to 9%, respectively (trend p = 0.001). Along with a reduction in the overall prevalence of osteopenia (86.3% to 83.1%, p=0.001), the prevalence of both preDM and DM decreased from 39.2% to 32.6% and 10% to 9% (p = 0.001). In those with osteoporosis, the prevalence of preDM decreased from 45.2% to 34.4% (p trend=0.001), however, the prevalence of DM increased from 7.5% to 8.7% (p trend =0.001). Overall rates of uncontrolled DM (HbA1c &amp;gt; 7%) in women with osteoporosis showed significant improvement (5.8% to 3.5%, p = 0.001). Discussion Despite worsening trend in femoral neck BMD among US women age ≥ 50 years from 2009-10 to 2017-18, the overall prevalence of preDM and DM improved by 7.1% and 0.6% respectively. However, this favorable trend was not observed among women with osteoporosis, where the overall prevalence of DM increased by 1.2%, though the rate of uncontrolled DM significantly decreased by 2.3%. Targeted interventions to improve blood glucose control among women with low BMD, especially those with osteoporosis are warranted, to improve bone health, as well as reduce fall and fracture risk.

6577 National Trends in Fragility Hip Fractures Among Community Dwelling Women With Low Femoral Neck Bone Mineral Density

Abstract Disclosure: A. Atri: None. C. Anastasopoulou: None. Introduction: Fragility hip fractures are a major public health burden and are considered a good measure of the quality of healthcare. However, contemporary trends in fragility hip fractures in women with low femoral neck bone mineral density (BMD) in the United States are not known. Methods: We used data from the National Health and Nutrition Examination Survey (NHANES) for the years 2009-10, 2013–14 and 2017–18 to include U.S. women aged ≥ 60 years with bone mineral density (BMD) T score ≤ -1 at the femur neck, which was measured by dual energy x-ray absorptiometry (DEXA) on Hologic Discovery Model A Densitometers (Hologic, Inc., Bedford, Massachusetts). Fragility fracture at the hip was defined as self-reported hip fracture resulting from a fall from standing height or less. Participants with missing BMD and fracture data were excluded. ANOVA was used for comparing means. The Cochran-Armitage test was utilized for trend analysis. Results: Overall, in women aged ≥ 60 years with femoral neck T score ≤ -1, the average age of women of low BMD decreased from 71(±7.2) years to 69.6 (±6.7) years, whereas the mean T-score modestly worsened from – 1.96 (±0.62) to -2.04 (±0.77) from 2009-10 to 2017-18. Similarly, the prevalence of women with T score ≤ -2.5 increased from 18.1% to 21.3%. We also found no significant change in proportion of women who reported treatment for osteoporosis (2009-10: 19.8%, 2013-14: 18.5%, 2017-18: 19.7%; p trend = 0.052). However, proportion of women who experienced fragility hip fractures decreased significantly (2009-10: 2.4%, 2013-14: 1.5%, 2017-18: 1.2%; p trend = 0.001). The mean age of index fragility hip fracture was 70.6 years in 2009-10, 68.3 years in 2013-14 and 71.7 years in 2017-18 (p = 0.001). Age stratified analysis showed a decreasing trend in proportion of women ≥ 80 years who experienced their index fragility hip fracture (2009-10: 25.9%, 2013-14: 14.7%, 2017-18: 15%; p trend = 0.001) and 70-79 years (2009-10: 40.9%, 2013-14: 21.1%, 2017-18: 35.8%; p trend = 0.001), while an increasing trend was seen in women 60–69 years (2009-10: 33.2%, 2013-14: 64.2%, 2017-18: 49.2%; p trend = 0.001). Discussion In this nationally representative cohort of community-dwelling US women with a low femoral neck BMD, we found a 50% decrease in burden of fragility hip fractures over a 10-year period from 2009-10 to 2017-18. This trend was observed despite worsening mean femoral neck T-scores, T score ≤ -2.5, and similar rates of osteoporosis treatment. Interestingly, the proportion of women who experienced their index fragility hip fracture showed a declining trend among the 70-79 years and ≥ 80 years age-groups. This change may be due to increasing awareness and utilization of measures to decrease falls such as exercise, nutrition, health education and environment modifications targeted towards the elderly population.

6578 National Trends in Vitamin D Deficiency and Racial-Ethnic Differences Among US Women With Low Bone Mineral Density

Abstract Disclosure: A. Atri: None. C. Anastasopoulou: None. Introduction: Vitamin D (Vit D) plays a critical role in maintaining bone mineralization and its deficiency adversely impacts bone health. Contemporary trends of Vit D deficiency (VDD) and racial-ethnic differences in these trends among US women with low bone mineral density (BMD) are not well elucidated. Methods: We used data from the National Health and Nutrition Examination Survey (NHANES) for the years 2009-10, 2013–14 and 2017–18 to include U.S. women ≥ 50 years with femoral neck T score ≤ -1. Osteoporosis was defined by a T-score ≤ -2.5. BMD assessment in NHANES was not completed in 2011–12 and 2015–16, and therefore not included in the analysis. Femoral neck BMD was measured by dual energy x-ray absorptiometry (DEXA) on Hologic Discovery Model A Densitometers (Hologic, Inc., Bedford, Massachusetts). VDD was defined as serum 25(OH)D &amp;lt;30 nmol/L. Participants with missing data on race-ethnicity, BMD and Vit D data were excluded. Independent samples median test was used for comparing medians. The Cochran-Armitage test was utilized for trend analysis. Results: Overall, in women with low BMD, from 2009-10 to 2017-18, prevalence of osteoporosis increased from 13.7% to 16.9% while VDD decreased significantly from 5.6% to 2.3% (p trend = 0.001). When stratified by race-ethnicity, the prevalence of osteoporosis increased in Whites (14.1% to 17.6%, p trend = 0.001), Hispanics (12.6% to 13.7%, p trend = 0.001) and Other race-ethnicity (Asian/Mixed) (14.1% to 21.4%, p trend = 0.001), but a modest decrease was noted among the Black population (7.3% to 6.8%, p trend = 0.001). VDD was disproportionately high among Blacks (In 2009-10: 28.1% vs 4.2% in Whites, 5.4% in Hispanics and 10.7% among Others). However, significantly improving trends in VDD were observed among all the groups, regardless of race/ethnicity, to 12.5% prevalence among Blacks, 1.3% in Whites, 4.9% in Hispanics and 1.1% in the Other race ethnicity group (p trend = 0.001). Discussion In this contemporary analysis, rates of VDD have decreased from nearly 1 in 20 to 1 in 50 women with low BMD in the US. Highest prevalence of VDD was noted among Blacks, seen in nearly 1 in 3 Black women in 2009-10, with improvement to 1 in 8, in 2017-18. Similar favorable trends of decline in VDD were observed across all other racial-ethnic groups as well. Despite the overall improvement in VDD, prevalence of osteoporosis declined only among Black women, suggesting the potential role of other protective factors against osteoporosis among them. Nevertheless, VDD continues to remain prevalent in this high-risk group, emphasizing the need for public health interventions to bridge this gap. Presentation: 6/2/2024

7334 Changing Trends In Oral Bisphosphonate Therapy: A 25-Year Surveillance In A US Healthcare System

Abstract Disclosure: J.C. Lo: None. M. Chandra: None. M.M. Khan: None. L.D. Carbone: None. E.A. Garcia: None. G.H. Tabada: None. D. Low: None. R.L. Hui: None. Introduction: Bisphosphonate (BP) drugs remain one of the first line therapies for fracture prevention, but treatment patterns have changed since BPs were first approved for osteoporosis. This study examines trends among adults initiating oral BP in a large US healthcare system over a 25-year period (1988-2022) and in each successive 5-year period. Methods: The study cohort comprised adults aged 50-89y who initiated alendronate, risedronate or oral ibandronate during 1998-2022 in an integrated healthcare delivery system, excluding those with select bone disorders, multiple myeloma, secondary metastatic cancer, end stage renal disease, and receipt of intravenous BP. Covariates included age (proportion age &amp;lt;65y), sex, race and ethnicity, and prior fracture (diagnosed within 5 years) using electronic health record data. Demographic trends and fracture status were examined across time periods. The chi-squared test and Cochrane-Armitage test for trend were used to examine differences and trends. This report extends findings from an earlier report of women initiating oral BP during 2004-2012 in the same healthcare population. Results: Among 208,780 adults (86% women) who initiated BP, including 26,646 (1998-2002, 35% &amp;lt;65y), 44,726 (2003-2007, 35% &amp;lt;65y), 34,005 (2008-2012, 24% &amp;lt;65y), 35,248 (2013-2017, 19% &amp;lt;65y), and 38,743 (2018-2022, 17% &amp;lt;65y) women and 2348 (1998-2002, 28% &amp;lt;65y), 4895 (2003-2007, 26% &amp;lt;65y), 5172 (2008-2012, 17% &amp;lt;65y), 5331 (2013-2017, 13% &amp;lt;65y), and 11,666 (2018-2022, 5% &amp;lt;65y) men in each 5-year period. Over time, an increasing proportion were age ≥65y (p&amp;lt;0.001 for trend), with larger numbers of older adults in later years partly reflecting initiatives targeting secondary fracture prevention (since 2008 for women, 2015 for men) and BMD screening (since 2011 for women, 2017 for men). Among women initiating BP, the proportion with prior fracture increased from 24-30% (pre-2008) to 43-45% (post-2008), partly reflecting secondary fracture prevention initiatives for women. For men, this proportion increased from 33% (1998-2002) to 42% (2003-2007), 47% (2008-2012), and 54% (2013-2017), but fell to 36% (2018-2022) after BMD screening initiatives began in 2017 for older men (primary prevention efforts). Racial and ethnic diversity in treatment also increased, comparing 1988-2002 (75.2% White, 2.5% Black, 8.6% Hispanic, 12.7% Asian/Pacific Islander) to 2018-2022 (61.5% White, 2.9% Black, 12.2% Hispanic, 21.1% Asian/Pacific Islander, p&amp;lt;0.001 for overall differences and % non-White). Conclusions: In a primary care population of adults initiating oral BP, a larger proportion in later years were age &amp;gt;65y, including larger numbers both with and without fracture coinciding with initiatives for fracture prevention. Among those initiating BP, the relative proportions with prior fracture in each period were likely influenced by primary or secondary prevention efforts. Presentation: 6/2/2024

Postpartum Glucose Follow-up Screening Among Women With Gestational Diabetes Mellitus: A Retrospective Cohort Study

Abstract Objective To evaluate the impact of pre-gestational and gestational characteristics on postpartum glucose follow-up screening (PGFS) compliance in women diagnosed with gestational diabetes mellitus (GDM) in southwest China. Methods This retrospective cohort study was conducted in West China Second Hospital, Sichuan University. Pre-gestational and gestational factors were extracted from hospital records and compared between women who completed PGFS and those who did not. The screening method chosen was the 75g oral glucose tolerance test (OGTT), performed 4–12 weeks postpartum. Univariate analysis, logistic regression analysis, and Cochran-Armitage test were used to assess associations between maternal characteristics and PGFS compliance. Results A total of 3047 women with GDM were included, with a PGFS completion rate of 47.2%. Of those who completed PGFS, 430 women (29.9%) presented abnormal results: 1.8% with impaired fasting glucose (IFG), 24.1% with impaired glucose tolerance (IGT), 2.2% with both IFG and IGT 2.2%, and 1.8% with suspected diabetes. Independent factors associated with non-compliance to PGFS included higher pre-gestational BMI (odds ratio (OR): 0.952; 95% confidence interval (CI): 0.922, 0.984), multipara (OR: 0.721; 95% CI: 0.593, 0.877), use of assisted reproduction technology (ART) (OR: 1.427; 95% CI: 1.080, 1.885), excessive gestational weight gain (OR: 0.956; 95% CI: 0.936, 0.977), elevated fasting plasma glucose (FPG) prior to delivery (OR: 0.909; 95% CI: 0.835, 0.988), and undergoing cesarean section (OR: 1.232; 95% CI: 1.017, 1.492) were independent influencing factors of failing to PGFS. PGFS completion rates significantly decreased with increasing pre-gestational BMI and earlier gestational age (P &lt; 0.001). Conclusions Establishing dedicated postpartum follow-up teams and targeting women with higher pre-gestational BMI, multiparity, ART use, excessive gestational weight gain, elevated pre-delivery FPG, and those undergoing cesarean section are critical to improving postpartum GDM management.
