Self-identity explains better breastfeeding intention of ethnic pregnant mothers of Western Nepal: Extending the theory of planned behavior.

Breastfeeding intention is one of the strongest predictors of breastfeeding behavior and practice. The Theory of Planned Behavior (TPB), with its main construct, behavioral intention, is useful to predict actual behavior. While the literature has examined the implications of other theoretical notions such as self-identity, moral norm, descriptive norm, and socio-demographic variables, their roles remain unclear. Similarly, research on ethnic and low-income mothers is even insufficient. Therefore, given the original TPB constructs, our goal was to examine the role of extra theoretical constructs and specific demographic variables, and observe whether the original model would alter. A cross-sectional analytical study was carried out among 325 pregnant mothers in six purposively selected health care facilities of Kaski and Tanahu districts, using structured pro forma, from December 2018 to November 2019. We developed stepwise multivariate logistic regression from the entered and cleaned data, observed the effects on breastfeeding intention (BFI), and checked against multiple parameters. We interpreted the model with adjusted odds ratios and β coefficients, along with the variance explained. Out of 325 pregnant women, more than half (54.8%) were primiparous, and the mean age was 25.1±5 years. All three theoretical constructs of TPB regressed the BFI significantly, with 10.7%, the breastfeeding attitude dominating (β = 0.734, p = .003), and the other two constructs-perceived breastfeeding control (β = 0.659, p = .011) and breastfeeding subjective norm (β = 0.504, p = .045). Interestingly, breastfeeding self-identity added further variance of 5.2% (β = 0.955, p < .001), followed by income, with 3.2% (β = 0.856, p = .001), both of which also tallied large effect sizes. The model parameters showed consistency and robustness. We discuss the variables of the theoretical and extended model for BFI as well as the arguments for the explained variance. Self-identity is a strong and independent predictor of breastfeeding intention and, therefore, should be considered to better prepare for breastfeeding, especially among ethnic pregnant mothers. The direct and intermediate effects of self-concept and income need further study with more robust designs.

Why do patients stay in hospital after enhanced recovery thoracoscopic wedge resection? A prospective observational study.

This single-centre prospective observational study aimed to investigate reasons for prolonged hospitalization (over the median length of stay [LOS]) after enhanced recovery thoracoscopic (ERAS 3-port VATS) wedge resection. All patients were evaluated twice daily by an investigator for reasons of hospitalization. Each reason was analysed individually. Predictors for prolonged hospitalization were identified using a multivariable backward stepwise logistic regression model. A total of 150 consecutive patients (lymphadenectomy 8.7%) were included from November 2022 to December 2023, with a median LOS of 1 (interquartile range 1-2) day. Of these, 55 patients (36.7%) experienced prolonged hospitalization. The main reasons included postoperative pain (16.0%), air leak (14.7%), and social factors (14.7%), followed by oxygen dependency (7.3%), gastrointestinal factors (5.3%), urinary factors (4.7%), pneumonia (1.3%), pleural effusion (1.3%), chylothorax (0.7%), atrial fibrillation (0.7%), confusion (0.7%), and fatigue (0.7%). Multivariable analysis revealed that an increase in percentage of predicted forced expiratory volume in 1 second (FEV1%pre) by 1% (odds ratio [OR] 0.41, P = 0.023) and percentage of predicted diffusing capacity for carbon monoxide (DLCO%pre) by 1% (OR 0.95, P = 0.002) decreased likelihood of prolonged hospitalization. Conversely, each additional pack-year (OR 1.01, P = 0.028) and living alone (OR 3.55, P = 0.005) increased the risk of prolonged hospitalization. Prolonged hospitalization (LOS > 1 day) after ERAS 3-port VATS wedge resection, with 8.7% lymphadenectomy, was mainly due to pain, air leak, and social factors. Smokers with decreased FEV1%pre or DLCO%pre and patient living alone were at increased risk.

12620 Developing Hospital Protocols For Managing Patients With Hypertriglyceridemia-induced Acute Pancreatitis In Diabetic Ketoacidosis Hospitalizations

Abstract Disclosure: U. Agbedia-ejughemre: None. Methods: We queried the combined 2017-2020 nationwide inpatient sample database for all adult hospitalizations for DKA with and without HTG-AP using the ICD-10 revision codes. Baseline characteristics were compared between DKA hospitalizations with and without HTG-AP using Pearson’s χ2 tests and Student’s t-test for categorical and continuous variables. Study endpoints were the incidence, predictors, and outcomes of HTG-AP, including mortality, hospitalization duration, mean hospital costs, and acute in-hospital complications (sepsis, ARDS, and acute renal failure). Predictors of HTG-AP were assessed using stepwise multivariable logistic regression analysis. Illness severity, baseline risk of mortality, and comorbidity burden were adjusted using APR-DRG metrics and CCI. Prolonged hospitalization was defined as the length of hospital stay in the top decile of hospital stay for all hospitalizations in the study. Results: We analyzed 630,435 hospitalizations for DKA. The study cohort was 51.4% male, 57.6% white Americans and 26.1% Blacks, with a mean age of 40 (SD, 16.2) years. Incidence of HTG-AP was 2.1% (13,445). Hospitalizations with HTG-AP were older (mean age: 44 vs. 40 years; P&amp;lt;0.001) and had greater comorbidity (CCI score of 2: 38.7 vs. 33.8; P&amp;lt;0.001) compared with DKA hospitalizations without HTG-AP. While DKA hospitalizations showed an uptrend, increasing from 105,769 to 199,429 hospitalizations (Average annual percent change [AAPC]: 27.04%; P=0.029), the incidence of HTG-AP showed a downtrend from 2650 (2.5%) to 4085 (2.0%) (P=0.006). Predictors of HTG-AP included Hispanic (aOR: 2.45; 95% CI: 1.95-3.07; P&amp;lt;0.001) or Asian race (aOR: 2.48; 95% CI: 1.37-4.48; P=0.003), private insurance (aOR: 1.57; 95% CI: 1.10-2.25; P=0.013), self-pay (aOR: 2.2; 95% CI: 1.49-3.27; P&amp;lt;0.001), APR-DRG moderate risk of mortality (aOR: 1.52; 1.21-1.92; P&amp;lt;0.001), APR-DRG major loss of function (aOR: 1.46; 95% CI: 1.31-1.69; P&amp;lt;0.001), dyslipidemia (aOR: 1.87; 95% CI: 1.47-2.38; P&amp;lt;0.001), hypertension (aOR: 1.39; 95% CI: 1.13-1.72; P=0.002), obesity (aOR: 3.09; 95% CI: 2.42-3.96; P&amp;lt;0.001), obstructive sleep apnea (aOR: 2.05; 95% CI: 1.35-3.10; P=0.001), chronic liver disease (aOR: 9.44; 95% CI: 6.61-13.48; P&amp;lt;0.001), old MI (aOR: 2.11; 95% CI: 1.02-4.38; P=0.045), and COPD (aOR: 2.31; 95% CI: 1.47-3.64; P&amp;lt;0.001). DKA hospitalizations with HTG-AP were correlated with higher risk of septicemia (aOR: 1.20; 95% CI: 1.05-1.69; P=0.029), ARDS (aOR: 1.24; 95% CI; 1.04-2.07; P=0.004), and resource use, including prolonged hospitalization (26.3% vs. 11.1%; P&amp;lt;0.001), and higher mean hospital costs ($57,773 vs. $32,692; P&amp;lt;0.001). Conclusion: HTG-AP was linked to worse outcomes, excluding mortality, in hospital admissions for DKA. There is a need for enhanced diagnostic guidelines and protocols targeting this subgroup of patients could improve outcomes. Presentation: 6/2/2024

NODESAFE Nomogram: A Novel Score System to Predict Lymph Node Involvement at the Time of Nephrectomy or Nodal Recurrence in Non-Metastatic Renal Cell Carcinoma

ObjectiveWe sought to develop a preoperative nomogram called NODESAFE (NODE SAFEty) to predict nodal involvement (NI) at time of surgery or subsequent follow up in localized renal cell carcinoma (RCC), as the role of lymphadenectomy in localized RCC remains controversial. MethodsWe conducted a multicenter retrospective analysis of RCC patients who underwent primary surgical resection. Patients with clinical metastasis at presentation were excluded. NI was defined as presence of histological RCC with lymphadenectomy at time of surgery, or subsequent development histologically proven NI. The dataset was divided into training (70%) and testing subsets to facilitate model evaluation which was constructed through a stepwise multivariable logistic regression (MLR) model. Accuracy was tested with receiver operator characteristic estimated area under the curve (AUC). Results3,308 patients [2,221 (67.1%) male) met inclusion criteria. During follow-up 25 patients (0.76 %) experienced nodal recurrence, and 22/25 were preoperatively classified as cN0. In our cohort, 112 (3.4%) patients had clinical lymphadenopathy preoperatively (cN1), and 34/112 were pN1. The following covariates were found to be statically significant on a MLR model: hypertension [Odds ratio (OR) 3.35, <0.001], Charlson Comorbidity Index≥5 (OR 1.93 p=0.025), tumor size≥6 cm (OR 2.63, p=0.001), tumor necrosis at CT scan (OR 1.83, p=0.036), cN1 (OR 5.59, p<0.001) and CRP≥8.5 mg/L (1.96, p=0.018). Testing the prediction performance of the model in the validation set AUC of the model was 0.89. NODESAFE demonstrated a sensitivity of 83.9%, specificity of 86.1% and 99.1% negative predictive values using a 4% threshold probability. ConclusionCombining clinical features, serum biomarkers and radiographic findings, we developed a model capable of predicting NI with high degree of accuracy. NODESAFE may refine clinical decision making with respect to the performance of lymphadenectomy at the time of surgery, post-surgical surveillance, and spur consideration for adjuvant therapy. Micro AbstractWe designed and internally validate a preoperative nomogram (NODESAFE) combining clinical features, serum biomarkers and radiographic findings, which predict loco regional lymph node involvement at time of surgery resection or subsequent locoregional nodal recurrence.

Risk factors and outcomes of conversions in robotic and laparoscopic liver resections: A nationwide analysis

BackgroundUnfavorable intraoperative findings or incidents during minimally invasive liver surgery may necessitate conversion to open surgery. This study aimed to identify predictors for conversion in minimally invasive liver surgery and gain insight into outcomes following conversions. MethodsThis nationwide, retrospective cohort study compared converted and non-converted minimally invasive liver surgery procedures using data from 20 centers in the Dutch Hepatobiliary Audit (2014–2022). Propensity score matching was applied. Subgroup analyses of converted robotic liver resection versus laparoscopic liver resection and emergency versus non-emergency conversions were performed. Predictors for conversions were identified using backward stepwise multivariable logistic regression. ResultsOf 3,530 patients undergoing minimally invasive liver surgery (792 robotic liver resection, 2,738 laparoscopic liver resection), 408 (11.6%) were converted (4.9% robotic liver resection, 13.5% laparoscopic liver resection). Conversion was associated with increased blood loss (580 mL [interquartile range 250–1,200] vs 200 mL [interquartile range 50–500], P < .001), major blood loss (≥500 mL, 58.8% vs 26.7%, P < .001), intensive care admission (19.0% vs 8.4%, P = .005), overall morbidity (38.9% vs 21.0%, P < .001), severe morbidity (17.9% vs 9.6%, P = .002), and a longer hospital stay (6 days [interquartile range 5–8] vs 4 days [interquartile range 2–5], P < .001) but not mortality (2.2% vs 1.2%, P = .387). Emergency conversions had increased intraoperative blood loss (1,500 mL [interquartile range 700–2,800] vs 525 mL [interquartile range 208–1,000], P < .001), major blood loss (87.5% vs 59.3%, P = .005), and intensive care admission (27.9% vs 10.6%, P = .029), compared with non-emergency conversions. Robotic liver resection was linked to lower conversion risk, whereas American Society of Anesthesiologists grade ≥3, larger lesion size, concurrent ablation, technically major, and anatomically major resections were risk factors. ConclusionBoth emergency and non-emergency conversions negatively impact perioperative outcomes in minimally invasive liver surgery. Robotic liver resection reduces conversion risk compared to laparoscopic liver resection.

Financial needs and opioid use among head and neck cancer (HNC) survivors: Baseline findings from the HN-STAR trial (WF-1805CD).

365 Background: HNC survivors often experience post-treatment pain. Given known disparities in pain management and opioid use in the non-cancer population, we explored sociodemographic predictors of opioid use in HNC survivors enrolled in the HN-STAR trial (NCT04208490, funding: American Cancer Society and UG1CA189824). Methods: Survivors of HNC (stages I-III) who completed therapy 6-24 months prior and had no evidence of disease were enrolled throughout the NCI Community Oncology Research Program (NCORP). Survivors were randomized to a clinical informatics intervention or usual care. Baseline surveys elicited recent prescription opioid use in the prior week (yes/no). Blinded to arm assignment, we conducted bivariate analyses of recent opioid use and the following sociodemographic predictors: age, gender, marital status, race and ethnicity (non-white/Latinx vs all others), highest level of education, and being able to meet daily financial needs in the prior 4 weeks. We conducted stepwise multivariable logistic regression to evaluate the association of these factors on opioid use. Results: Among 254 survivors (mean age 63, 74% male, 25% non-white/non-Latinx, 13% reporting financial need) at 25 oncology practices, 14% (n=35) reported recent opioid use. In bivariate analyses, survivors who reported financial needs were more likely to have used opioids (odds ratio [OR] 4.35, 95% confidence interval [CI] 1.85-10.20, p&lt;.001). In stepwise multivariable analyses, only having financial needs remained in the final model (Table). Conclusions: In a national sample of post-treatment HNC survivors during a subacute survivorship period (6-24 months after treatment completion), 1 in 7 survivors reported using opioids in the past week – more than twice the annual rate of opioid receipt in the general adult population. Several demographic factors related to opioid use were examined and not associated with recent opioid use among HNC survivors. Findings suggest that financial concerns may be a barrier to non-narcotic pain management (e.g., cognitive behavioral approaches, physical therapy) – or simply that unmet financial needs are associated with lower quality of pain management. Attention should focus on equitable pain management in this population. Clinical trial information: NCT04208490 . Predictors of opioid use in past week.

Natriuretic peptides and soluble ST2 improves echocardiographic diagnosis of elevated left ventricular filling pressures

Elevated filling pressure of the left ventricle (LV) defines diastolic dysfunction. The gold standard for diagnosis is represented by the measurement of LV end-diastolic pressure (LVEDP) during cardiac catheterization, but it has the disadvantage of being an invasive procedure. This study aimed to investigate the correlation between LVEDP and cardiac serum biomarkers such as natriuretic peptides (mid-regional pro-atrial natriuretic peptide [MR-proANP], B-type natriuretic peptide [BNP], and N-terminal prohormone BNP [NT-proBNP]), soluble ST2 (sST2), galectin-3 and mid-regional pro-adrenomedullin (MR-proAMD). Consecutive patients hospitalized in a tertiary center and undergoing left cardiac catheterization were included in the study. Diastolic dysfunction was considered present if the end-expiratory LVEDP was ≥ 15 mmHg. Cardiac biomarkers were determined from pre-procedural peripheral venous blood samples. A total of 110 patients were included, of whom 76 (69.0%) were males, with a median age of 65 (55–71) years. Median LVEDP was 13.5 (8–19) mmHg and diastolic dysfunction was present in 50 (45.4%) of the patients. LVEDP correlated with BNP (p < 0.0001, r = 0.39 [0.20–0.53]), NT-proBNP (p < 0.0001, r = 0.40 [0.22–0.55]), MR-proANP (p = 0.001, r = 0.30 [0.11–0.46]), sST2 (p < 0.0001, r = 0.47 [0.30–0.60]), but not with MR-proAMD (p = 0.77) or galectin-3 (p = 0.76). In the final stepwise multivariable binary logistic regression model, diastolic dysfunction was predicted by NT-proBNP, mitral average E/e’, sST2, atrial fibrillation, and left atrium reservoir strain. BNP, NT-proBNP, MR-proANP, and sST2 had predictive value for diastolic dysfunction. In contrast, galectin-3 and MR-proAMD were not associated with increased filling pressures. Furthermore, NT-proBNP and sST2 significantly improved diastolic dysfunction prediction in the final multivariable model.

Nomogram for predicting the risk of nosocomial infections among obstetric inpatients: a large-scale retrospective study in China

ObjectiveThis study aimed to develop and validate a nomogram for assessing the risk of nosocomial infections among obstetric inpatients, providing a valuable reference for predicting and mitigating the risk of postpartum infections.MethodsA retrospective observational study was performed on a cohort of 28,608 obstetric patients admitted for childbirth between 2017 and 2022. Data from the year 2022, comprising 4,153 inpatients, were utilized for model validation. Univariable and multivariable stepwise logistic regression analyses were employed to identify the factors influencing nosocomial infections among obstetric inpatients. A nomogram was subsequently developed based on the final predictive model. The receiver operating characteristic (ROC) curve was utilized to calculate the area under the curve (AUC) to evaluate the predictive accuracy of the nomogram in both the training and validation datasets.ResultsThe gestational weeks > = 37, prenatal anemia, prenatal hypoproteinemia, premature rupture of membranes (PROM), cesarean sction, operative delivery, adverse birth outcomes, length of hospitalization (days) > 5, CVC use and catheterization of ureter were included in the ultimate prediction model. The AUC of the nomogram was 0.828 (0.823, 0.833) in the training dataset and 0.855 (0.844, 0.865) in the validation dataset.ConclusionThrough a large-scale retrospective study conducted in China, we developed and independently validated a nomogram to enable personalized postpartum infections risk estimates for obstetric inpatients. Its clinical application can facilitate early identification of high-risk groups, enabling timely infection prevention and control measures.

Association between parental factors and child's behaviors during moderate sedation in pediatric dental care.

Managing young children with negative behaviors can be challenging in dental settings. Moderate sedation (MS) is often used as a treatment option for such children. However, children's behavior during MS may vary depending on several variables. These variables include parental factors, such as parental anxiety, coping strategies, and pain catastrophizing. However, this area, particularly in Saudi Arabia, remains underexplored. Therefore, this study aimed to assess the association among parental anxiety, coping style, pain catastrophizing, and children's behavior during MS among Saudi children. Based on sample size calculation, this cross-sectional observational study included 85 children aged 3-5 years undergoing dental treatment under MS at King Saud University, Riyadh, Saudi Arabia. Parental anxiety, coping styles, and pain catastrophizing were assessed using the Modified Dental Anxiety Scale, Brief Coping Orientation to Problems Experienced Scale, and Pain Catastrophizing Scale. Child behavior was evaluated using the Houpt scale during sedation visits, which was video-recorded and independently analyzed by a single evaluator. Data were analyzed using Pearson's chi-squared test, Mann-Whitney U test, and stepwise multivariate logistic regression analyses. The results showed no significant association among parental dental anxiety, pain catastrophizing, and child behaviors during MS. Specific parental coping strategies, such as acceptance, were positively associated with positive sedation outcomes (P = 0.03), while active coping strategies were linked to less favorable outcomes (P = 0.03). Female children had higher sedation failure rates (P = 0.02), and the number of dental treatments was positively associated with success rates (P = 0.03). Parental anxiety and pain catastrophizing did not significantly affect the success of sedation. However, acceptance as a coping strategy was significantly associated with sedation success in pediatric dental care under MS, whereas active coping strategies were associated with less favorable outcomes.

Establishment and validation of a nomogram model containing a triglyceride-glucose index and neutrophil-to-high-density lipoprotein ratio for predicting major adverse cardiac events in patients with ST-segment elevation myocardial infarction.

To analyze the predictive value of the triglyceride-glucose (TyG) index and neutrophil-to-high-density lipoprotein ratio (NHR) for in-hospital major adverse cardiac events (MACE) after percutaneous coronary intervention (PCI) in patients with acute ST-segment elevation myocardial infarction (STEMI), and to establish an associated nomogram model. In this retrospective study, we collected data from consecutive STEMI patients who underwent PCI from October 2019 to June 2023 at the Second People's Hospital of Hefei and the Second Affiliated Hospital of Anhui Medical University, as training and validation sets. Stepwise regression and multivariate logistic regression analysis were performed to screen independent risk factors, and a nomogram model was constructed and evaluated for its predictive efficacy. The TyG index, NHR, urea, diastolic blood pressure, hypertension, and left ventricular ejection fraction were independent risk factors for in-hospital MACE after PCI, and were used to construct the nomogram model. The C-index of the training and validation sets were 0.799 and 0.753, respectively, suggesting that the model discriminated well. Calibration and clinical decision curves also demonstrated that the nomogram model had good predictive power. In STEMI patients, increased TyG index and NHR were closely related to the occurrence of in-hospital MACE after PCI. Our constructed nomogram model has some value for predicting the occurrence of in-hospital MACE in STEMI patients.

A Novel Preoperative Risk Score to Identify Patients at High Risk for Non-Home Discharge After Elective Open Abdominal Aortic Aneurysm Repair

Non-home discharge (NHD) to a rehabilitation or skilled nursing facility after vascular surgery is poorly described despite its impact on patients. For home-dwelling patients undergoing elective surgery, the need for postoperative NHD can have meaningful implications on quality of life, long-term outcomes, and healthcare spending. Understanding post-surgical NHD risk is essential to preoperative counseling and shared decision making. This is particularly true for the treatment of abdominal aortic aneurysms as the postoperative course can vary between open and endovascular surgery. We aimed to identify independent predictors of NHD following elective open abdominal aortic aneurysm repair (OAR), and to create a clinically useful preoperative risk score. Elective OAR cases were queried from the SVS Vascular Quality Initiative from years 2013-2022. A risk score was created by splitting the data set into two-thirds for development and one-third for validation. A parsimonious stepwise hierarchical multivariable logistic regression controlling for hospital level variation was performed in the development dataset, and the beta-coefficients were used to assign points for a risk score. The score was then validated, and model performance assessed. Overall, 8,274 patients were included and 1,502 (18.2%) required NHD. At baseline, patients who required NHD were more likely to be ≥ 80 years old (23.6% vs. 6.5%), female (35.9% vs. 23.1%), not independently ambulatory (14.6% vs. 4.3%), anemic (24.4% vs. 13.9%), have COPD (41.6% vs. 30.7%), ASA class ≥ 4 (41.0% vs. 32.5%), and a supraceliac proximal clamp (9.8% vs. 5.7%; all P<0.05). Multivariable analysis in the development group identified the following independent predictors of NHD: age ≥ 80 years, not independently ambulatory, proximal clamp location, hypogastric artery occlusion, anemia (Hb <12 g/dL), chronic obstructive pulmonary disease, female sex, hypertension, and American Society of Anesthesiologists class ≥ 4. These were then used to create a 14-point risk score. Patients were stratified into three groups based upon their risk score: low risk (0-4 points; n=4,966) with an NHD rate of 9.9%, moderate risk (5-6 points; n=2,442) with an NHD rate of 25.5%, and high risk (≥ 7 points; n=886) with an NHD rate of 44.6%. The risk score had good predictive ability with c-statistic=0.73 for model development and c-statistic=0.72 in the validation dataset. This novel risk score can predict NHD following elective OAR using characteristics that can be identified preoperatively. Utilization of this score may allow for improved risk assessment, preoperative counseling, and shared decision making.

Risk Factor for Rash in Patients Receiving Cytarabine and Idarubicin Induction Therapy for Acute Myeloid Leukemia.

Rash is a common adverse event (AE) observed during cytarabine and idarubicin induction therapy in patients with acute myeloid leukemia (AML). Previous studies have highlighted the challenge in predicting the onset and duration of rash. This study aimed to determine the factors that affect the onset of rash in patients receiving induction therapy for AML. This retrospective study involved 97 patients with AML who received induction chemotherapy with cytarabine and idarubicin at the Department of Hematology, Kyushu University Hospital between January 2008 and June 2022. The factors associated with rash were identified through a multivariate stepwise logistic regression analysis. Subsequently, the patient's characteristics were compared between those with risk factors and those without risk factors using a matched pair analysis. Pre-existing leukopenia [odds ratio (OR)=3.294; 95% confidence interval (CI)=1.272-8.531] and good performance status (PS=0) (OR=2.717; 95%CI=1.087-6.792) were significant risk factors for rash development. Conversely, the matched pair analysis indicated that patients with pre-existing leukopenia, excluding those with a PS score of 0, exhibited a significantly (p=0.015) higher incidence of rash than those without it. Both multivariate logistic regression analysis and matched pair analysis identified pre-existing leukopenia as a primary risk factor for rash development associated with cytarabine and idarubicin chemotherapy.

Risk Factors Related to the Development of Full-thickness Pressure Injuries in Hospitalized Pediatric Patients.

Current pediatric pressure injury (PI) prevention measures are based on risk factors related to PI development in adults. Children offer a unique concern for PI development because their bodies are still developing, and their skin responds differently to external pressure. To explore risk factors for the development of full-thickness PIs in children aged 21 weeks' gestation to 21 years. This retrospective, observational, correlational study included 799 hospitalized children who developed a PI. The pediatric and adult PI risk factors used in the study were identified from the International Pressure Ulcer Prevention and Treatment Guideline. A stepwise multivariate logistic regression model was used. Multivariate analyses revealed that risk factors for predicting a full-thickness PI varied by age. For children aged 38 weeks to 12 months, risk factors included tissue perfusion and oxygenation: generalized edema, conditions of the OR, and nutrition deficits. For children aged 1 to 7 years, fragile skin status was a risk factor. For youth aged 8 to 21 years, the two risk factors were tissue perfusion and oxygenation: decreased oxygenation and extracorporeal membrane oxygenation. Across the total sample, extracorporeal membrane oxygenation, tissue perfusion and oxygenation: decreased oxygenation and malnutrition were risk factors for predicting a full-thickness PI. Full-thickness PI risk factors differ among the ages of pediatric patients.

Social networks and COVID-19 vaccination intention in Dutch middle-aged and older adults in 2020: Insights into individual, interpersonal, community, and societal determinants – The SaNAE study

BackgroundSocial networks, our social relationships, influence the spread of infectious diseases and preventive behaviors such as vaccination. Here, we aimed to assess which individual, interpersonal (social network characteristics), community and societal factors are associated with coronavirus disease 2019 (COVID-19) vaccination intention during the second wave of the COVID-19 pandemic in 2020, prior to vaccine availability. MethodsThis cross-sectional study collected primary data from 5,001 community-dwelling adults aged 40 years and older in the Netherlands, using an online questionnaire from August and November 2020. COVID-19 vaccination intention was measured by assessing whether respondents were willing to receive a COVID-19 vaccination if the vaccines became available. Associations between individual (sociodemographic variables, health, health concerns), interpersonal (social network characteristics including structure, function, and quality), community (social and labor participation) and societal factors (degree of urbanization), and the outcome variables COVID-19 vaccination intention (yes vs no, yes vs unsure, unsure vs no) were assessed in stepwise multivariable logistic regression analyses. p-values < 0.05 indicated statistical significance. ResultsAmong participants (N = 3,396), 59 % reported a positive intention to vaccinate, 35 % were unsure, and 6 % had no intention. Men, individuals of older age, those with a college or university degree, those concerned about their personal and family health, and knowledge about protecting oneself from the virus were more likely to have the intention to vaccinate (versus no intention). Interpersonal factors associated included having a larger network size (social network structure) and a larger proportion of informational supporters (social network function). Living outside of urban areas, a societal factor, was associated with vaccination intention (versus no intention). ConclusionThis study identified key factors influencing COVID-19 vaccination intention. Health promotion efforts should address not only individual factors but also incorporate the social environment. Our findings highlight the importance of organizing social networks to mobilize social support for pandemic preparedness.

Detection of colorectal advanced neoplasms among the cancer screening population in urban areas of Henan Province and analysis on its influencing factors

Objective: To analyze the detection of colorectal advanced neoplasms in the population who underwent colonoscopy screening in Henan Province as part of the Urban China Cancer Screening Program and its influencing factors. Methods: A cross-sectional study design was employed. Based on the Cancer Screening Program conducted in Henan Province, the study enrolled 7 454 urban residents who manifested no symptoms and were recruited from eight cities in the province, including Zhengzhou, Zhumadian, Anyang, Luoyang, Nanyang, Jiaozuo, Xinxiang, and Puyang from October 2013 to October 2019, and participated in colonoscopy screening. The χ2 test was used to compare the detection rates of colorectal advanced neoplasms among participants with different characteristics, and a multivariate logistic stepwise regression model was used to analyze the factors affecting the detection rates. Results: A total of 7 454 subjects underwent colonoscopy screening, and 112 cases of colorectal advanced neoplasms were detected. Multivariate logistic regression analysis suggested that older age, smoking, higher meat intake, history of diabetes, and family history of colorectal cancer in a first-degree relative were risk factors for colorectal advanced neoplasms. The detection rate was significantly higher in people aged 60-74 years compared with those aged 40-49 years, with an odds ratio (OR) of 2.04 (95% CI: 1.23-3.38).The rates were higher in people who smoked than those who did not smoke, with an OR of 2.21 (95% CI: 1.48-3.31), and in people who consumed more meat than those who consumed less, with an OR of 1.53 (95% CI: 1.04-2.26). Those with diabetes had a higher detection rate compared with those without, with an OR of 1.69 (95% CI: 1.07-2.69), and those with a first-degree family history of colorectal cancer had a higher detection rate than those without, with an OR of 1.64 (95% CI: 1.09-2.46). Conclusion: The detection rate of colorectal advanced neoplasms through colonoscopy screening in Henan Province covered by the Urban China Cancer Screening Program is 1.50%. Older age, smoking, higher meat intake, history of diabetes, and family history of colorectal cancer in a first-degree relative are identified as risk factors for colorectal advanced neoplasms.

Risk factors for in-hospital mortality in recipients of allogeneic hematopoietic stem cell transplantation with acute respiratory distress syndrome: a retrospective study based on the 2023 new definition of acute respiratory distress syndrome

IntroductionARDS (acute respiratory distress syndrome) is the most severe form of acute hypoxic respiratory failure. Most studies related to ARDS have excluded patients with hematologic diseases, let alone allogeneic hematopoietic stem cell transplantation (allo-HSCT) recipients. Numerous patients experiencing severe hypoxic respiratory failure do not meet the Berlin definition due to the limitations of diagnosis and treatment. A new definition of ARDS, remove some diagnosis restrictions, was proposed in 2023. Based on the 2023 new definition of ARDS, we investigated the clinical features of ARDS in allo-HSCT recipients and reported risk factors for in-hospital mortality in allo-HSCT recipients defined by the Berlin definition and the new definition of ARDS respectively.MethodsFrom Jan 2016 to Dec 2020, 135 allo-HSCT recipients identified with the new definition and 87 identified with the Berlin definition at three teaching hospitals were retrospectively included in this study. Variables (demographic information, characteristics of hematologic disease and ARDS episode, laboratory tests and SOFA score) with P < 0.05 in univariate logistic regression analysis were included in multivariate stepwise logistic regression analysis. Adjusted odds ratios (ORs) and 95% confidence intervals (95% CIs) were reported.ResultsUnder the new definition, SOFA score (OR = 1.351, 95% CI: 1.146–1.593, P < 0.01) were found as an independent risk factor for in-hospital mortality in ARDS after allo-HSCT, while SpO2/FiO2 (OR = 0.984, 95% CI: 0.972–0.996, P < 0.01) was a protective factor. The infusion of peripheral-derived stem cells was found to be a protective factor against in-hospital mortality in post-transplantation ARDS compared with the infusion of bone marrow-derived stem cells (OR = 0.726, 95% CI: 0.164–3.221, P = 0.04). Under the Berlin definition, PaO2/FiO2 (OR = 0.977, 95% CI: 0.961–0.993, P = 0.01, lactate (OR = 7.337, 95% CI: 1.313–40.989, P < 0.01) and AST (OR = 1.165, 95% CI: 1.072–1.265, P < 0.01) were independently associated with in-hospital mortality.ConclusionThese prognostic risk factors we found in allo-HSCT recipients may contribute to closer monitoring and ARDS prevention strategies. These findings require confirmation in prospective, large sample size studies.

The Near-infrared Visualization and Pre-emptive Ligation of the Thoracic Duct Effectively Reduce the Chyle Leak Incidence After Minimally Invasive Esophagectomy.

The aim of the present study is to assess the effectiveness of indocyanine-green (ICG)-guided lymphography (ICG-Lg) in reducing the incidence of chyle leak (CL) after esophagectomy. Chylothorax may severely impact esophageal cancer surgery, and the pre-emptive ligation of the thoracic duct (TD) is the most widespread control of this complication. Intraoperative ICG-Lg has been recently embedded in minimally invasive esophagectomy to facilitate TD detection and pre-emptive ligation. This retrospective analysis included consecutive patients who underwent minimally invasive Ivor Lewis esophagectomy for cancer at a tertiary referral center between January 2018 and August 2023. Patients were routinely submitted to extended lymphadenectomy with TD ligation and removal. All patients treated after January 2021 underwent ICG-Lg for TD identification and ligation (ICG group) and compared to the previous series (no-ICG group). The primary outcome was the incidence of postoperative CL, while univariate and backward stepwise multivariate logistic regression models were performed to identify associated factors. After including 320 patients, 151 (ICG group) were submitted to ICG-Lg before the pre-emptive TD ligation. Both groups presented similar characteristics, except for neoadjuvant therapy (P=<0.001) and preoperative comorbidities (P=0.045). Intraoperative ICG-Lg significantly reduced the incidence of postoperative CL (11.8% vs 4.6%, P=0.026) and was significantly associated with shorter median length of hospital stay (13 vs 9 days, P=0.006). However, CL after ICG-Lg was more likely to require repairing reoperation (P=0.050). Intraoperative ICG-Lg demonstrated significantly lower rates of CL after total minimally invasive esophagectomy and, therefore, it should be routinely embedded in the standardized surgical technique of high-volume centers for esophageal cancer.

How Is Human Socioeconomic Position Linked With Dog Ownership Practices? A Study From Denmark

ABSTRACT Connections between dog ownership and socioeconomic position (SEP) are not well understood. This study examined associations between family and neighborhood levels of SEP and dog ownership, dog acquisition factors (purchase price and breed characteristics), and the purposes of owning a dog based on data from a survey carried out in Denmark in 2021. Participants (aged 18–89 years) were recruited using probability sampling (n = 2,112). Stepwise multivariable logistic or multinomial logistic regressions were conducted to identify significant associations with SEP. Approximately 20% of families in Denmark have a dog. Dog ownership was not found to be linked with income, education, or occupation when life course and lifestyle factors were taken into account. Neighborhood SEP was associated with dog ownership, but the association was not ordered. Payment of a high price for the dog was more prevalent both in high-SEP neighborhoods and in high-income families. Dog owners with low income and limited involvement in the labor market were more likely to have mixed-breed dogs. Those with a higher income and the self-employed were more likely to have a pedigree dog. Acquiring a dog to get physical exercise was more common among dog owners living in high-SEP neighborhoods. Owners with higher levels of education were more likely to have a dog because they liked the company of animals, and those with lower levels tended to keep a dog for instrumental reasons and for social support. The reason for keeping a dog for social support was mainly observed among those with lower levels of education who were also frequently (often/sometimes) involuntarily alone. As in many other areas of consumption, the results demonstrate that acquisition of, and reasons for keeping, a dog are linked to socioeconomic status. They also suggest that dogs play different roles in emotional and mental health at different educational levels.

Predicting intraoperative major blood loss in microsurgery for brain arteriovenous malformations.

Intraoperative blood loss poses a great challenge for brain arteriovenous malformation (AVM) microsurgery, although systematic researches are still lacking. This study aimed to identify factors predicting intraoperative major blood loss in brain AVM microsurgery and to investigate its impact on patient outcome. To deal with the fierce bleeding, we introduced a modified hemostatic method, bone-wax (BW) coated bipolar electrocoagulation. The authors retrospectively analyzed the clinical data of 131 patients (50/81 in intraoperative major/non-major blood loss cohort) with brain AVMs who underwent microsurgery in our center during the period between January 2018 and April 2023. According to previous studies, major blood loss was defined as blood loss of at least 1,000 mL. The accuracy and objectivity of our grouping methodology were validated by comparing the hemoglobin mass loss, hematocrit loss and factors associated with intraoperative bleeding. Potential clinical and radiological predictors for intraoperative major blood loss were evaluated using a multivariate stepwise logistic regression. And outcomes of patients in the two cohorts were also compared. At last, the performance of BW coated bipolar electrocoagulation in brain AVM microsurgery was illustrated by the case presentation, histological staining and transmission electron microscopy of the coagulated nidus vessels. Hemoglobin mass loss, hematocrit loss and factors associated with intraoperative bleeding were significant different between the two cohorts. five independent factors predicting intraoperative major blood loss were identified: (1) clinical manifestations; (2,3) location and size of the nidus; (4) deep venous drainage; and (5) the number of draining veins. And the intraoperative major blood loss can not only adversely affect the surgical progression, but also predict poor perioperative outcomes for patients. Regarding the application of BW coated bipolar electrocoagulation, we found the novel hemostatic method exerted efficient hemostatic effect and reduced the damage to the vascular structure in brain AVM microsurgery. This study proposed a nomogram for neurosurgeons to predict intraoperative major blood loss in brain AVM microsurgery preoperatively. And intraoperative major blood loss is associated with poor patient outcomes. In addition, BW coated bipolar electrocoagulation, can be applied to control ferocious bleeding during brain AVM microsurgery, which still remains further researches.
