Associations of HIV and antiretroviral therapy with gestational diabetes in South Africa.

To estimate associations of HIV status and antiretroviral (ART) regimen with gestational diabetes (GDM) and postpartum glucose metabolism. Prospective cohort study. We enrolled pregnant persons with HIV (PWH) and without HIV in Cape Town, South Africa who were at least 18 years of age at 24-28 weeks' gestation and followed up to 26 months postpartum. Participants were tested for GDM in pregnancy and for diabetes postpartum using a 75 g 2 h oral glucose tolerance test (OGTT) and diagnosed via WHO criteria. We estimated associations of HIV status and ART regime [efavirenz (EFV) versus dolutegravir (DTG)] with GDM and postpartum impaired glucose metabolism using multivariable log binomial or linear regression models. Among 397 participants [median age 30 (interquartile range (IQR) 25-34; n = 198 without HIV, n = 199 PWH], the prevalence of GDM was 6% (9 PWH versus 3% without HIV). In multivariable analyses, PWH were at higher risk of GDM [risk ratio (RR) 3.9, 95% confidence interval (CI) 1.4-10.7] after adjustment for prepregnancy BMI and other confounders. GDM risk did not differ by ART regimen (unadjusted prevalence 8.1% DTG versus 5.6% EFV, adjusted RR 1.1, 95% CI 0.2-6.6). Few participants had diabetes, impaired glucose tolerance (IGT), or impaired fasting glucose postpartum ( n = 13, 6%) with no differences by HIV or ART status. In a setting of universal GDM testing, PWH had an increased risk of impaired glucose metabolism during pregnancy but not postpartum. Among PWH, GDM risk was similar regardless of EFV or DTG use. Given concerns about DTG and weight gain, diabetes risk should continue to be monitored.

Despite Increased Disease Activity, Women who Attended a Dedicated Inflammatory Bowel Disease and Pregnancy Clinic Had Infants With Higher Apgar Scores: A Population-Based Study.

Attendance at a subspecialty pregnancy clinic for women with inflammatory bowel disease (IBD) improves disease-specific pregnancy knowledge. We examined the impact of attendance at a dedicated IBD-pregnancy clinic on IBD and perinatal outcomes. Using linked administrative databases in Alberta, Canada (2012-2019), we identified 1061 pregnant women with IBD who delivered singleton liveborn infants in-hospital who did (n = 314) and did not attend (n = 747) the clinic. Propensity score weighted multivariable log-binomial and multinomial logistic regression models were used to determine the risk of IBD and perinatal outcomes. The median number of clinic visits was 3 (Q1-Q3, 3-5), with 34.7% completing a preconception consultation. A greater proportion of women who attended lived near the clinic, were nulliparous, had a disease flare prior to pregnancy, and were on maintenance IBD medication (P < .05). Women who attended had increased risks of a disease flare during pregnancy (adjusted risk ratio [aRR], 2.02; 95% CI, 1.45-2.82), an IBD-related emergency department visit during pregnancy (aRR, 2.66; 95% CI, 1.92-3.68), and cesarean delivery (aRR, 1.78; 95% CI, 1.23-2.57). Despite this, clinic attendees had a decreased risk of delivering an infant with a low Apgar score at 1 minute (risk ratio [RR], 0.49; 95% CI, 0.32-0.76) and 5 minutes (RR, 0.32; 95% CI, 0.12-0.87). Women who attended a dedicated IBD-pregnancy clinic were more likely to have a disease flare prior to pregnancy, reflecting a more severe disease phenotype, but had similar perinatal outcomes and infants with better Apgar scores at birth. Our study suggests the value of these subspecialty clinics in providing enhanced IBD-specific prenatal care.

A Brief Peer-Led Intervention to Increase COVID-19 Vaccine Uptake Among People Who Inject Drugs in San Diego County: Results From a Pilot Randomized Controlled Trial.

We evaluated the impact of a brief peer-led intervention on COVID-19 vaccination among people who inject drugs (PWID) presenting at syringe services program (SSP) locations in San Diego County, California. Between March and July 2022, PWID aged ≥18 years without recent voluntary COVID-19 testing who were not up to date on COVID-19 vaccinations received a single-session motivational interviewing intervention (LinkUP) or an attention-matched didactic control condition from trained peer counselors at SSP sites randomized by week. Following either 30-minute session, counselors offered referrals to local vaccination services. Multivariable log binomial regression via generalized estimating equations assessed LinkUP effects on (1) acceptance of COVID-19 vaccination referrals immediately postintervention and (2) COVID-19 vaccine uptake at 6-month follow-up. COVID-19 vaccination outcomes were obtained on 135 (90.6%) of 149 participants. In multivariable analysis, participants receiving LinkUP had greater acceptance of COVID-19 vaccination referrals than controls (adjusted relative risk, 3.50; 95% CI, 1.01-12.2) and were marginally more likely to report receiving a new COVID-19 vaccine dose (adjusted relative risk, 1.57; 95% CI, .99-2.48). After 6 months, 20% reported receiving a new vaccine dose; however, if COVID-19 vaccine had been available at SSPs, this proportion could have been as high as 34.3% (45.3% LinkUP vs 24.3% control; P = .01). A brief peer-led SSP-based intervention significantly improved COVID-19 vaccination among PWID. Further improvements could likely be obtained by supporting SSPs to offer COVID-19 vaccination on-site instead of relying on referrals. ClinicalTrials.gov NCT05181657.

Relationship between pulse pressure and body mass index in active-duty Royal Thai Army personnel in Thailand

BackgroundElevated pulse pressure (PP) is a robust independent predictor of cardiovascular diseases. The relationship between PP and body mass index (BMI) was presented in a few studies. However, the findings were inconsistent. Therefore, the aim of the present study is to identify the association between elevated PP and BMI using a large sample of active-duty Royal Thai Army (RTA) personnel.MethodsA cross-sectional study was conducted through the use of the dataset obtained from the annual health examination database of RTA personnel in Thailand in 2022. BMI 25.0–29.9 kg/m2 was classified as obesity I, whereas BMI ≥ 30.0 kg/m2 was classified as obesity II. Elevated PP was defined as PP ≥ 50 mmHg. Multivariable linear regression and log-binomial regression models were utilized for determining the association between elevated PP and BMI.ResultsA total of 62,113 active-duty RTA personnel were included in the study. The average BMI was 25.4 ± 3.8 kg/m2, while the average PP was 50.1 ± 11.2 mmHg. Compared to individuals with normal weight, the beta coefficients of PP and BMI were 1.38 (95% CI: 1.15–1.60) and 2.57 (95% CI: 2.25–2.88) in individuals with obesity I and obesity II, respectively. Effect modification by high blood pressure (BP) on the association between elevated PP and BMI was observed. Among participants with normal BP, in comparison with BMI of 18.5–22.9 kg/m2, the adjusted prevalence ratio (PR) for elevated PP was 1.23 (95% CI: 1.19–1.28) and 1.41 (95% CI: 1.35–1.48) in those with obesity I and obesity II, respectively. Meanwhile, among individuals with high BP, the adjusted PR for elevated PP was 1.05 (95% CI: 1.01–1.08) and 1.09 (95% CI: 1.06–1.13) in those with obesity I and obesity II, respectively.ConclusionPP was positively associated with BMI in active-duty RTA personnel. High BP was the modifier of the association between PP and BMI. A weaker association between elevated PP and BMI was observed among RTA personnel with high BP.

A new tool to capture dimensions of family dinners in relation to adolescent health and risk-related outcomes: The ‘Family Dinner Index’

There is a strong association between family meals and child and adolescent health. To systematically understand the associations between family meals with a variety of health and risk outcomes, we developed and conducted a validation study of child- and parent-versions of the Family Dinner Index (FDI; FDI-C/FDI-P). We validated the measures with a national sample of 2,090 parent–child dyads. Using factor analysis, we reduced the initial FDIs each to eight items representing communication, enjoyment, and digital distractions; the FDI-C also included meal logistics and the FDI-P, family bonding. Using multivariable log-binomial regression models, we examined the relationships between FDI scores and substance use, violence, weight perception, weight control intention, and health indicators. Children who scored ≥21 on the FDI-C had a significantly lower average prevalence of a ‘negative outcome’ composite, as well as a lower prevalence of each of the individual behaviors. Children of parents who scored ≥24 on the FDI-P had a significantly lower average prevalence of the ‘negative outcome’ composite, as well as a lower prevalence of substance use indicators, negative weight perception and intentions to lose weight, less than daily fruit and vegetable consumption, and not meeting guidelines for physical activity. The FDI measures provide support for face and content validity, as well as concurrent criterion validity and construct validity. Further validation with these measures using a longitudinal design will allow for the establishment of predictive validity. Currently, the FDI measures may help researchers and practitioners identify points of emphasis for tailoring family-based prevention programs accordingly.

Comparison of guideline concordant antibiotic prophylaxis in Veterans Affairs and non-Veterans Affairs dental settings among those with cardiac conditions or prosthetic joints

BackgroundNo research has been conducted to assess whether antibiotic prophylaxis prescribing differs by dental setting. Therefore, the goal of this study was to compare the prescribing of antibiotic prophylaxis in Veterans Affairs (VA) and non-Veterans Affairs settings.MethodsThis was a retrospective study of veteran and non-veteran dental patients with cardiac conditions or prosthetic joints between 2015–2017. Multivariable log binomial regression analysis was conducted to compare concordant prescribing by setting with a sub-analysis for errors of dosing based on antibiotic duration (i.e., days prescribed).ResultsA total of 61,124 dental visits that received a prophylactic antibiotic were included. Most were male (61.0%), and 55 years of age or older (76.2%). Nearly a third (32.7%) received guideline concordant prophylaxis. VA dental settings had a lower prevalence of guideline concordant prescribing compared to non-VA settings in unadjusted results (unadjusted prevalence ratio [uPR] = 0.92, 95% CI: 0.90–0.95). After adjustment, prevalence of guideline concordant prescribing was higher in those with prosthetic joints in the VA setting (adjusted prevalence ratio [aPR] = 1.73, 95% CI: 1.59–1.88), with no difference identified in those without a prosthetic joint (aPR = 0.99, 95% CI: 0.96–1.01). Concordance of dosing was higher in VA compared to non-VA settings (aPR = 1.11, 95% CI: 1.07–1.15).ConclusionsVA has a higher prevalence of guideline concordant prescribing among those with prosthetic joints and when assessing dosing errors. Though the presence of an integrated electronic health record (EHR) may be contributing to these differences, other system or prescriber-related factors may be responsible. Future studies should focus on to what extent the integrated EHR may be responsible for increased guideline concordant prescribing in the VA setting.

Sociodemographic and reproductive risk factors associated with obesity in a population of brazilian women from the city of Ribeirão Preto: a cross-sectional study

BackgroundObesity is a highly prevalent chronic disease that is associated with the development of other metabolic comorbidities. Its etiology is complex and multiple risk factors have been reported. In women, weight gain during pregnancy and the effect of pregnancy on subsequent weight gain are important events in women’s history. Both pregnancy and postpartum are critical periods for the development of obesity.ObjectivesTo identify sociodemographic and reproductive risk factors associated with obesity in women in their fourth decade of life.MethodsCohort study conducted on women born from June 1978 to May 1979 in Ribeirão Preto, Brazil. Sociodemographic, clinical, and obstetric data were collected by interview and clinical evaluation. Univariable and multivariable binomial logistic regression models were constructed to identify the risk factors of obesity and the adjusted relative risk (RR) was calculated.ResultsThe cohort included 916 women and 309 (33.7%) of them were obese. Obesity was associated with low educational level (RR 1.77, 95%CI 1.33–2.35) and teenage pregnancy (RR 1.46, 95%CI 1.10–1.93). There was no association of obesity with the other covariates studied.ConclusionObesity is associated with years of schooling and teenage pregnancy.

Supportive relationships in childhood: Does it have a long Reach into health and depression outcomes for immigrants from Latin America?

This study examines how social support during childhood and adolescence is associated with self-rated good health and the incidence of depression among Latin American immigrants in the U.S. We focus on those who immigrated under age 18 (childhood arrivals) to understand the interplay between early social support and adult health outcomes. Data are from the 2012–2013 iteration of the National Epidemiologic Survey on Alcohol and Related Conditions (NESARC-III), which included a sample of 3441 immigrant respondents born in Latin America. Multivariable binomial logistic regression analyses indicated that childhood and interpersonal support in adulthood were negatively associated with lifetime major depressive disorder (LMDD) episodes. These associations differed between childhood arrival and adult arrival immigration samples. Findings from this study highlight the role that social support in critical developmental periods has on immigrant health and depression outcomes. Continued and more nuanced investigations are warranted to examine social resources across lifespans and their roles in mitigating adverse health outcomes among immigrants from Latin America.

Assessment of Radiologic Extranodal Extension Using Combinatorial Analysis of Nodal Margin Breakdown and Metastatic Burden in Oropharyngeal Cancer

The importance of risk stratification in the management of oropharyngeal squamous cell carcinoma (OPSCC) is becoming increasingly obvious with the growing evidence of its variable prognosis. We identified and evaluated imaging characteristics predictive of extranodal extension (ENE) in OPSCC. Preoperative computed tomography and histopathologic results of 108 OPSCC patients who underwent neck dissection as primary treatment were analyzed. Imaging characteristics were reassessed for factors associated with nodal margin breakdown and metastatic burden. Moreover, the predictability of pathological ENE (pENE) was analyzed. Univariate and multivariate binomial logistic regression analyses were performed to examine the predictive power of ENE-related radiologic features. Imaging-based characteristics showed variable degrees of association with pENE. Factors associated with nodal margin breakdown (indistinct capsular contour, irregular margin, and perinodal fat stranding) and factors associated with nodal burden (nodal matting, lower neck metastasis, and presence of &gt;4 lymph node metastases) were significantly predictive of ENE (odds ratio (OR) = 11.170 and 12.121, respectively). The combined utilization of the nodal margin and burden factors further increased the predictive ability (OR = 14.710). Factors associated with nodal margin breakdown and nodal burden were associated with pENE, demonstrating the use of combinatorial analysis for more accurate ENE prediction.

Prevalence and risk factors of prehypertension/hypertension among freshman students from the Vietnam National University: a cross-sectional study

BackgroundPrehypertension (PHT) and hypertension (HTN) in young adults are essential risk factors for other cardiovascular diseases (CVD) in later years of life. However, there is a lack of knowledge about the burden and risk factors of PHT/HTN for Vietnamese youth. The aim of this study was to investigate the prevalence of PHT/HTN and risk factors among university students in Hanoi, Vietnam.MethodsThis study was designed as a cross-sectional investigation with 840 students (394 males and 446 females) randomly sampled from freshmen of Vietnam National University, Hanoi (VNU). Socio-demographic, anthropometric, and lifestyle data were collected using questionnaire forms and physical measurements. HTN was defined as blood pressure (BP) ≥ 140/90 mmHg and/or current treatment with antihypertensive medications. PHT was defined as a systolic BP from 120 to 139 mmHg and/or a diastolic BP from 80 to 89 mmHg. Body mass index (BMI) was classified according to the WHO diagnostic criteria for Asian adults: normal weight (BMI 18.5–22.9 kg/m2), underweight (BMI < 18.5 kg/m2), overweight (BMI 23–24.9 kg/m2), and obese (BMI ≥ 25 kg/m2). Bivariable and multivariable log-binomial regression analyses were conducted to explore the association of PHT/HTN with different risk factors.ResultsThe overall prevalence of prehypertension and hypertension was 33.5% [95% CI: 30.3–36.8%] (54.1% in men and 15.3% in women) and 1.4% [95% CI: 0.7–2.5%] (2.5% in men and 0.5% in women), respectively. Regarding CVD major risk factors, 119 (14.2%) were identified as overweight/obese, 461 (54.9%) were physical inactivity, 29.4% of men and 8.1% of women reported consuming alcohol. The multivariable analysis indicated the male sex (adjusted prevalence ratio [aPR] = 3.07; 95% CI: 2.32–4.06), alcohol consumption (aPR = 1.28; 95% CI: 1.03–1.59) and obesity (aPR = 1.35; 95% CI: 1.08–1.68) as the independent risk factors for PHT/HTN.ConclusionsThe results revealed the high burden of prehypertension and hypertension among university freshmen in VNU. Male sex, alcohol consumption, and obesity were identified as important risk factors for PHT/HTN. Our study suggests an early screening program for PHT/HTN and campaigns to promote a healthy lifestyle for young adults in Vietnam.

Partner-Support and Gestational Duration Among Pregnant Women Who Smoke.

Pregnant women who smoke are at a high risk of preterm birth (PTB) and have low partner-support. In a prospective cohort study, we aimed to examine the role of partner-support in gestational duration and PTB among pregnant women who smoke as well as the interaction with race/ethnicity. We analyzed secondary data of 53 participants from the University at Buffalo Pregnancy and Smoking Cessation Study. Partner-support was measured with Turner's support scale where women reported how much they agreed with five statements about how supportive their partner was. Total partner-support was calculated and split into emotional support and accountability. We fit multivariable linear regression models and log-binomial regression models for gestational duration and PTB, respectively. Gestational duration significantly increased with partner-support (0.22weeks longer per unit increment in partner-support score), emotional support (0.52weeks), and accountability (0.35weeks). This association tended to be stronger among Hispanics and women of other races than non-Hispanic Caucasians and African Americans. Women with a bed partner had 1.48weeks longer gestational duration than women without a bed partner. Partner-support may increase gestational duration and reduce PTB risk among pregnant women who smoke, especially among Hispanic women. Sharing a bed with a partner was associated with a longer gestational duration. Our findings may be interpreted with caution due to limitations such as small sample size, recruitment within a single metropolitan area, and partner-support measurement via maternal reports only. A partner-support intervention to increase gestational duration is warranted.

Bariatric surgery prior to elective shoulder arthroplasty: a Nationwide Inpatient Sample analysis

BackgroundObesity has been linked to adverse outcomes after various orthopedic procedures, and bariatric surgery is an effective surgical treatment for morbid obesity. This study assesses whether prior bariatric surgery is associated with differences in hospital length of stay (LOS), discharge destination, and inpatient complication rate for elective shoulder arthroplasty. MethodsThe Nationwide Inpatient Sample database was queried from years 2003 to 2014 for all elective anatomic and reverse total shoulder arthroplasty cases. Two groups were defined: morbidly obese without prior bariatric surgery (MO cohort) and prior bariatric surgery without morbid obesity (BS cohort). Outcome measures were LOS (extended if greater than the 75th percentile), discharge destination (home or non-home), and any inpatient complication. Patients under age of 18 years and those with missing information were excluded. National estimates were calculated using weights provided by the Nationwide Inpatient Sample database. Chi-squared tests were performed for demographics and comorbidities. Binomial multivariate logistic regression was performed using significant demographics and comorbidities. ResultsA weighted-total of 19,877 patients were included in the study, of which 2783 were in the BS cohort and 17,094 were in the MO cohort. The BS group was younger (62.9 years vs. 66.0 years), had more females (73% vs. 69%), and was more likely to be anemic (15% vs. 10%). The MO group was more likely to have diabetes (40% vs. 22%), hypertension (83% vs. 65%), and peripheral vascular disease (3% vs. 1%). Multivariate analysis showed that the BS cohort had decreased odds of extended LOS (odds ratio [OR], 0.68), non-home discharge destination (OR, 0.67), and developing any inpatient complication (OR, 0.42). ConclusionIn the setting of anatomic and reverse total shoulder arthroplasties, patients with prior bariatric surgery and without morbid obesity had more favorable hospital LOS, discharge destination, and inpatient complication rate than morbidly obese patients with no prior bariatric surgery. Further studies are warranted to better elucidate the relationship between bariatric surgery and shoulder arthroplasty.

Prognostic Language in Critical Neurologic Illness: A Multicenter Mixed-Methods Study.

There are no evidence-based guidelines for discussing prognosis in critical neurologic illness, but in general, experts recommend that clinicians communicate prognosis using estimates, such as numerical or qualitative expressions of risk. Little is known about how real-world clinicians communicate prognosis in critical neurologic illness. Our primary objective was to characterize prognostic language clinicians used in critical neurologic illness. We additionally explored whether prognostic language differed between prognostic domains (e.g., survival, cognition). We conducted a multicenter cross-sectional mixed-methods study analyzing deidentified transcripts of audio-recorded clinician-family meetings for patients with neurologic illness requiring intensive care (e.g., intracerebral hemorrhage, traumatic brain injury, severe stroke) from 7 US centers. Two coders assigned codes for prognostic language type and domain of prognosis to each clinician prognostic statement. Prognostic language was coded as probabilistic (estimating the likelihood of an outcome occurring, e.g., "80% survival"; "She'll probably survive") or nonprobabilistic (characterizing outcomes without offering likelihood; e.g., "She may not survive"). We applied univariate and multivariate binomial logistic regression to examine independent associations between prognostic language and domain of prognosis. We analyzed 43 clinician-family meetings for 39 patients with 78 surrogates and 27 clinicians. Clinicians made 512 statements about survival (median 0/meeting [interquartile range (IQR) 0-2]), physical function (median 2 [IQR 0-7]), cognition (median 2 [IQR 0-6]), and overall recovery (median 2 [IQR 1-4]). Most statements were nonprobabilistic (316/512 [62%]); 10 of 512 prognostic statements (2%) offered numeric estimates; and 21% (9/43) of family meetings only contained nonprobabilistic language. Compared with statements about cognition, statements about survival (odds ratio [OR] 2.50, 95% CI 1.01-6.18, p = 0.048) and physical function (OR 3.22, 95% 1.77-5.86, p < 0.001) were more frequently probabilistic. Statements about physical function were less likely to be uncertainty-based than statements about cognition (OR 0.34, 95% CI 0.17-0.66, p = 0.002). Clinicians preferred not to use estimates (either numeric or qualitative) when discussing critical neurologic illness prognosis, especially when they discussed cognitive outcomes. These findings may inform interventions to improve prognostic communication in critical neurologic illness.

Carbapenemase genes and mortality in patients with carbapenem-resistant Enterobacterales, Atlanta, Georgia, 2011–2020

Background: Carbapenemase genes in carbapenem-resistant Enterobacterales (CP-CRE) may be transmitted between patients and bacteria. Reported rates of carbapenemase genes vary widely, and it is unclear whether having a carbapenemase gene portends worse outcomes given that all patients with CRE infections have limited treatment options. Methods: Using active population- and laboratory-based active surveillance data collected by the US CDC-funded Georgia Emerging Infections Program from 2011 to 2020, we assessed the frequency of carbapenemase genes in a convenience sample of CRE isolates using whole-genome sequencing (WGS), and we investigated risk factors for carbapenemase positivity. Only the first isolate per patient in a 30-day period was included. We compared characteristics of patients with CP-CRE and non–CP-CRE. Using multivariable log binomial regression, we assessed the association of carbapenemase gene positivity and 90-day mortality. Results: Of 284 CRE isolates, 171 isolates (60.2%) possessed a carbapenemase gene (Table 1), and KPC-3 was the most common carbapenemase gene (80.7%), with only 7 isolates possessing NDM (Table 2). No isolates possessed &gt;1 carbapenemase gene, and most isolates were from urine (82.4%) (Table 1). Carbapenemase gene positivity was associated with lower age, male sex, black race, infection with Klebsiella pneumoniae, polymicrobial infection, having an indwelling medical device, receiving chronic dialysis, and prior stay in a long-term acute-care hospital, long-term care facility, and/or prior hospitalization in the last year. The 90-day mortality rates were similar in patients with non–CP-CRE and CP-CRE: 24.8% versus 25.7% (P = .86). In multivariable analysis, carbapenemase gene presence was not associated with 90-day mortality (adjusted risk ratio, 0.82; 95% CI, 0.50–1.35) when adjusting for CCI, infection with Klebsiella pneumoniae, and chronic dialysis use. Conclusions: The frequency of CP-CRE among CRE was high in this study, but unlike prior studies, the 90-day mortality rates wer similar in patients with CP-CRE compared to non–CP-CRE. Our results provide novel associations (eg, lower age, male sex, infection with Klebsiella pneumoniae, and indwelling medical devices) that infection preventionists could use to target high-risk patients for screening or isolation prior to CP-CRE detection.Disclosure: None

Comorbidities in patients with sarcoma: Insights from the National In-Patient Database from 2006 to 2014.

e23534 Background: Sarcoma represents a rare solid malignancy in adults. Given the likelihood of metastatic disease, the prognosis is usually poor. Comorbidities are independent determinants of prognosis, and cardiovascular and respiratory diseases are the most common. We aimed to study the prevalence, trends, and outcomes of CVD and pulmonary circulation disorders in patients admitted with sarcoma over eight years. Methods: We present a retrospective analysis of hospital admissions for soft tissue malignancies between 2006 and 2014 from the NIS database using its respective ICD-9-CM code. We obtained the prevalence of cardiovascular diseases (HF, CAD, HTN) and pulmonary circulatory disorders (PE, PHTN). We assessed yearly trends with the Cochran-Armitage trend test. Using multivariate binomial logistic regression (adjusting for sex, race, age, and Elixhauser comorbidities) we calculated adjusted odds ratios (aOR) to identify the association of these comorbidities with in-hospital mortality. Results: Between 2006-2014 there were 352320 admissions with a primary diagnosis of soft tissue malignancies. Of them, 55.8% were males, 60% were white, and 57.5% were 50 years old and older. In 39% of the population, CVD was present: HTN 35.5%, CAD 8.5%, HF 4.5%. The rate of pulmonary circulatory disorders was 2.5%: PE 1.7%, and pulmonary hypertension 0.9%. In-hospital mortality accounted for 3.7% of admissions. The CVD yearly prevalence increased from 34.6% in 2006 to 41.7% in 2014 (p &lt; 0.001). Pulmonary circulatory disorders rose from 1.7% in 2006 to 3.3% in 2014 (p &lt; 0.001). Pulmonary circulatory diseases were associated with high in-hospital mortality aOR 3.02 (CI 95% 2.44-3.73, p = 0.00). Cardiovascular disease was not statistically significantly associated with an increased rate of in-hospital mortality aOR 1.04 (CI 95% 0.93-1.15, p = 0.53). Conclusions: In sarcoma patients, it is essential to quantify their comorbidities as these often influence their chosen therapy. Cardiovascular disease affected one-third of the patients. However, despite the low prevalence of pulmonary circulatory disorders, they were associated with high in-hospital mortality. Further studies are needed to understand the causality and underlying physiopathology.

Quality of End-of-Life Care for Older Adults with Dementia during the COVID-19 Pandemic.

End-of-life (EOL) care during the coronavirus disease 2019 (COVID-19) pandemic has been a concern under the overwhelming pressure of health care service systems. People with dementia often receive suboptimal EOL care; thus, they may be at particular risk of poor care quality during the COVID-19 pandemic. This study investigated the interaction between dementia and pandemic on the proxies' overall ratings and ratings for 13 indicators. A longitudinal study. Data were collected from 1050 proxies for deceased participants in the National Health and Aging Trends Study, a nationally representative sample of community-dwelling Medicare beneficiaries aged ≥65years. Participants were included if they had died between 2018 and2021. Participants were categorized into 4 groups depending on the period of death (before vs during the COVID-19 pandemic) and having no vs probable dementia, as defined by a previously validated algorithm. The quality of EOL care was assessed through postmortem interviews with bereaved caregivers. Multivariable binomial logistic regression analyses were performed to examine the main effects of dementia and pandemic period, and the interaction between dementia and pandemic on ratings of quality indicators. A total of 423 participants had probable dementia at the baseline. People with dementia who died were less likely to talk about religion in the last month of life than those without dementia. Decedents during the pandemic were more likely to have an overall rating of care as being not excellent than those before the onset of the pandemic. However, the interaction between dementia and pandemic was not significant in the 13 indicators and the overall rating of EOL care quality. Most EOL care indicators preserved the level of quality, regardless of dementia and the COVID-19 pandemic. Disparities in spiritual care may exist across people with and without dementia.

Association between physical performance during sit-to-stand motion and frailty in older adults with cardiometabolic diseases: a cross-sectional, longitudinal study

BackgroundAlthough physical performance tests of the lower extremities are used to assess sarcopenia and frailty, little is known about the mechanisms by which the parameters of ground reaction force (GRF) measured during sit-to-stand motion affect the frailty status in older adults. We aimed to examine the association between GRF parameters during sit-to-stand motion and the incidence of frailty in older adults.MethodsThis longitudinal study evaluated 319 outpatients aged ≥ 65 years with cardiometabolic diseases. The GRF parameters were measured using a motor function analyzer, in which the power, speed, and balance scores were calculated. Frailty was diagnosed using the modified version of the Cardiovascular Health Study (mCHS) and the Kihon Checklist (KCL). The independent associations between scores and frailty indices were assessed using multivariate binomial logistic regression analyses. Cox regression analysis was used to examine whether power and speed scores were associated with the incidence of frailty after adjusting for covariates.ResultsLogistic regression analyses adjusted for covariates showed that the power and speed scores were associated with frailty according to the mCHS criteria (power: OR = 0.37, 95% CI = 0.22–0.63; speed: OR = 0.64, 95% CI = 0.52–0.79) and KCL criteria (power: OR = 0.40, 95% CI = 0.26–0.62; speed: OR = 0.81, 95% CI = 0.69–0.96) at baseline. Receiver operating characteristic analyses revealed that the area under the curve values of power and speed scores for discriminating mCHS-defined frailty were 0.72 and 0.73. The Cox regression analysis showed that the speed score predicted the incidence of mCHS-defined (HR = 0.45, 95% CI = 0.22–0.92, P = 0.029) and KCL-defined (HR = 0.77, 95% CI = 0.60–0.99, P = 0.039) frailty, whereas the power score was associated with the incidence of KCL-defined frailty (HR = 0.72, 95% CI = 0.55–0.95, P = 0.02) after adjusting for covariates.ConclusionsThe speed and power scores measured during sit-to-stand motion are predictive of frailty in older adults with cardiometabolic disease. Therefore, the GRF parameters measured during sit-to-stand motion could be an important indicator of frailty. Further studies are necessary to examine whether the GRF parameters can be improved by exercise or whether the changes in these parameters are associated with the improvement of frailty status.

Respiratory Syncytial Virus, Influenza, and Coronavirus Disease 2019 Hospitalizations in Children in Colorado During the 2021-2022 Respiratory Virus Season

To compare demographic characteristics, clinical features, and outcomes of children hospitalized with respiratory syncytial virus (RSV), influenza, or severe acute respiratory syndrome coronavirus 2 during their cocirculation 2021-2022 respiratory virus season. We conducted a retrospective cohort study using Colorado's hospital respiratory surveillance data comparing coronavirus disease 2019 (COVID-19)-, influenza-, and RSV-hospitalized cases < 18years of age admitted and undergoing standardized molecular testing between October 1, 2021, and April 30, 2022. Multivariable log-binomial regression modeling evaluated associations between pathogen type and diagnosis, intensive care unit admission, hospital length of stay, and highest level of respiratory support received. Among 847 hospitalized cases, 490 (57.9%) were RSV associated, 306 (36.1%) were COVID-19 associated, and 51 (6%) were influenza associated. Most RSV cases were <4years of age (92.9%), whereas influenza hospitalizations were observed in older children. RSV cases were more likely to require oxygen support higher than nasal cannula compared with COVID-19 and influenza cases (P<.0001), although COVID-19 cases were more likely to require invasive mechanical ventilation than influenza and RSV cases (P < .0001). Using multivariable log-binomial regression analyses, compared with children with COVID-19, the risk of intensive care unit admission was highest among children with influenza (relative risk, 1.97; 95% CI, 1.22-3.19), whereas the risk of pneumonia, bronchiolitis, longer hospital length of stay, and need for oxygen were more likely among children with RSV. In a season with respiratory pathogen cocirculation, children were hospitalized most commonly for RSV, were younger, and required higher oxygen support and non-invasive ventilation compared with children with influenza and COVID-19.

519 Weekend Admission for Patients with Hidradenitis Suppurativa Have Better Outcomes than Weekday Admission

Abstract Introduction Hidradenitis suppurativa (HS) is a condition that involves recurring inflammation and fibrosis of intertriginous areas. With increasing inpatient hospitalization rates in patients with HS, our study sought to examine differences in outcomes between weekend and weekday admission. The authors hypothesized that patients admitted on a weekend will have worse in-hospital mortality rates when compared to those admitted on a weekday. Methods We used a national database to perform a cross-sectional study focusing on 12,365 patients with a primary diagnosis of HS from 2017-2019. The variables measured were weekend or weekday admission, age, gender, race, and zip income quartiles, with the latter four identified as confounding factors controlled for in the logistic regression analysis. Descriptive analyses were performed to determine frequencies, means, and significance. Statistical significance was set at p&amp;lt; 0.05.The multivariate binomial logistic regression was used to calculate the odds ratio (OR) for the identified outcomes. The primary outcome was in-hospital mortality. The secondary outcomes were morbidity factors (infection and wound dehiscence rates, postoperative complications), time from admission to first procedure, and resource utilization (total hospitalization charges and costs, and length of hospitalization). Results Weekend admission is not associated with worse inpatient mortality in patients with HS (p=0.345). From 2017-2019, 5 patients died, all of whom were admitted on a weekday. Compared to weekday, weekend admission had significantly lower incidences of wound dehiscence (0.38% vs 0%; p=0.007) and postoperative complications (0.24% vs 0%; p=0.035). No significant difference was observed for incidence of infection in weekday (0.43%) vs weekend admission (0.27%) (p=0.311). Weekend admission was also not found to have significant difference in the odds of contracting an infection (OR=0.74 (0.29-1.90); p=0.536). Weekend admission had significantly lower length of stay (mean days=6.40 vs 4.94; p=0.001), total charge ($64598.94 vs $44616.44; p&amp;lt; 0.001), and total cost ($14441.22 vs $10082.79; p&amp;lt; 0.001). Conclusions In contrast to previous studies focused on other pathologies that have shown increased morbidity, treatment metrics, and resource utilization on weekend admission, our study demonstrates that specifically for patients with HS, weekend admission is associated with lower rates of morbidity, length of stay, and charge. Applicability of Research to Practice Given that patients with HS who have a weekday admission have worse outcomes than a weekend admission, it is imperative for the medical team providing care to this group of patients on a weekday to be aware of this and begin to identify any potential factors.

The Utility of Inflammatory Serum Markers in the Assessment of Perioperative Morbidity after Radical Cystectomy for Bladder Cancer.

Background and Objectives: To date, sparse evidence exists about the impact of inflammatory serum markers in predicting perioperative complications after radical cystectomy (RC) for bladder cancer (BC). Here, we evaluated the role of the neutrophil-to-lymphocyte ratio (NLR), platelet-to-lymphocyte ratio (PLR), lymphocyte-to-monocyte ratio (LMR), systemic immune-inflammation index (SII), C-reactive protein (CRP), and plasma fibrinogen in predicting perioperative morbidity and unplanned 30-days readmission after RC for BC. Materials and methods: We relied on a collaborative database of 271 patients who underwent open RC for cT1-4a N0 M0 BC between January 2012 and December 2022. Univariable and multivariable binomial logistic regression analyses were performed to assess the odds ratio (OR) with 95% confidence intervals (CI) testing the ability of each serum marker to predict postoperative complications (any-grade and major complications), and 30-days unplanned readmission. Results: The median age at RC was 73 yr (IQR 67-79). A total of 182 (67.2%) patients were male and the median BMI was 25.2 (IQR 23.2-28.4). Overall, 172 (63.5%) patients had a Charlson Comorbidity Index (CCI) greater than 2 points and 98 (36.2%) were current smokers at the time of RC. Overall, 233 (86.0%) patients experienced at least one complication after RC. Of these, 171 (63.1%) patients had minor complications (Clavien-Dindo grade 1-2) while 100 (36.9%) experienced major complications (Clavien-Dindo grade ≥ 3). According to multivariable analysis, current smoking status, high plasma fibrinogen, and preoperative anemia were independently associated with major complications (OR 2.10, 95%CI 1.15-4.90, p = 0.02), (OR 1.51, 95%CI 1.26-1.98, p = 0.09), and (OR 1.35, 95%CI 1.17-2.57, p = 0.03), respectively. Overall, 56 (20.7%) patients experienced a 30-days unplanned readmission. According to univariable analysis, high preoperative CRP and hyperfibrinogenemia were significantly associated with an increased risk of unplanned readmission (OR 2.15, 95%CI 1.15-4.16, p = 0.02; OR 2.18, 95%CI 1.13-4.44, p = 0.02, respectively). Conclusions: In our study, the preoperative immune-inflammation signature described by NLR, PLR, LMR, SII, and CRP showed a low reliability in predicting perioperative course after RC. Preoperative anemia and hyperfibrinogenemia were independent predictors of major complications. Further studies are pending in order to draw definitive conclusions.
