Aging Well? Exploring Self-Reported Quality of Life in the Older Austrian Population Based on Repeated Cross-Sectional Data

ABSTRACT Increase in life expectancy around the world puts aging societies with all their challenges on the Global Public Health agenda. In Austria, additional years of life gained are not spent in good health, as healthy life expectancy is far below the European average. Using repeated cross-sectional data from three waves of the Austrian Health Interview Survey (2006, 2014 and 2019), including a total of 10,056 participants aged 65 years and above, this study examined the change in self-reported quality-of-life (QoL) over time and explored associated factors. QoL, estimated by domain scores of the WHOQOL-BREF questionnaire, increased over time but decreased with age in all survey waves. Observed mean scores were significantly higher in males than in females in all QoL domains except the social domain but sex differences disappeared in most domains in the multivariable regression analyses. Instead, factors associated with significantly higher QoL scores included younger age, higher socioeconomic status, living in Western Austria and having no chronic conditions. Statistically significant observed sex differences in QoL in the older-aged Austrian population disappeared when adjusting for income and education. Strategies and measures to increase financial capabilities may have a significant impact on QoL and well-being in this age group.

Serum concentration threshold and risk factors of tigecycline-induced hypofibrinogenaemia in critically ill patients

Abstract Objectives Hypofibrinogenaemia is a serious adverse reaction associated with tigecycline (TGC) therapy and may lead to the discontinuation of the treatment. This study aimed to explore the relevant factors of TGC-induced hypofibrinogenaemia and determine the thresholds of serum concentration as a predictive indicator of TGC-induced hypofibrinogenaemia. Methods A retrospective single-centre study was conducted on patients with severe infection who were treated with TGC. Clinical data and serum concentration parameters were extracted from the electronic medical records of these patients. Patients were divided into the hypofibrinogenaemia group (< 2.0 g/L) and the normal fibrinogen group (≥ 2.0 g/L) in order to evaluate risk factors associated with TGC-induced hypofibrinogenaemia. Logistic regression analysis and receiver operating characteristic curves were utilized to identify the risk factors associated with TGC-induced hypofibrinogenaemia and to establish plasma concentration thresholds as predictive indicators. Results A total of 114 patients were enrolled in this study, with 59.6% experiencing hypofibrinogenaemia. The multivariate regression analysis indicated that baseline fibrinogen level, trough concentration (Cmin), peak concentration (Cmax), the concentration at 6 h after the dosing (C6h) and the area under the concentration–time curve over a 24-h period (AUC0–24) were significantly associated with hypofibrinogenaemia (P < 0.05). Furthermore, it was found that AUC0–24 is the optimal predictor of TGC-induced hypofibrinogenaemia. The optimal cut-off for the AUC0–24 of TGC in ICU patients was determined to be 17.03 mg h/L. Conclusions TGC exposure is highly predictive of TGC-induced hypofibrinogenaemia. We recommend closely monitoring plasma concentrations of TGC in patients to ensure patient efficacy and safety.

Serum levels of free light chains and syndecan-1 in patients with rheumatoid arthritis and systemic lupus erythematosus

Abstract Objectives Systemic autoimmune rheumatic diseases (SARDs) are characterized by chronic inflammation. Reliable biomarkers are crucial for diagnosis, monitoring disease progression and therapeutic responses. This study explores serum Syndecan-1 (SDC-1) as a biomarker for these conditions and its relationship with free light chain (FLC) levels. Methods A retrospective analysis was performed on sera from 60 patients with rheumatoid arthritis (RA) and from 60 with systemic lupus erythematosus (SLE), alongside 50 healthy donors (HD). Κ- and λ- FLCs were determined by turbidimetric assay, while SDC-1 levels by ELISA. Kruskal-Wallis test, Wilcoxon-Mann–Whitney U test, multivariable linear regression and Spearman’s correlation were employed to compare biomarker levels across groups and to explore correlations. Results SDC-1, κ-FLC, and λ-FLC were significantly increased in RA and SLE patients compared with HD (p< 0.001), while no significant differences in the κ/λ ratio were observed among the groups (p= 0.4). A significant difference in subject age was also identified. However, multivariate regression analysis indicated that RA and SLE are significantly associated with the levels of these markers, with minimal confounding by age. A significant correlation was observed separately in all groups between the FLC markers. Conversely, no correlation was detected between SDC-1 and FLCs, nor between these markers and age or disease activity indices. Conclusion Elevated serum levels of FLCs and SDC-1 in RA and SLE patients compared with HD underscore their potential as biomarkers for SARDs. The findings also suggest sustained plasma cell activation, supporting the multifaceted role of SDC-1 in the pathogenesis of SARDs.

Associations Between Vestibular Perception and Cognitive Performance in Healthy Adults.

A growing body of evidence has linked vestibular function to the higher-order cognitive ability in aging individuals. Past evidence has suggested unique links between vestibular function and cognition on the basis of end-organ involvement (i.e., otoliths versus canals). However, past studies have only assessed vestibular reflexes despite the diversity of vestibular pathways. Thus, this exploratory study aimed to assess associations between vestibular perception and cognition in aging adults to determine potential relationships. Fifty adults (21 to 84 years; mean = 52.9, SD = 19.8) were included in this cross-sectional study. All participants completed a vestibular perceptual threshold test battery designed to target perception predominantly mediated by each end-organ pair and intra-vestibular integration: 1 Hz y-translation (utricle), 1 Hz z-translation (saccule), 2 Hz yaw rotation (horizontal canals), 2 Hz right anterior, left posterior (RALP), and left anterior, right posterior (LARP) tilts (vertical canals), and 0.5 Hz roll tilt (canal-otolith integration). Participants also completed standard assessments of cognition and path integration: Digit Symbol Substitution Test (DSST), Trail Making Test (TMT), and the Gait Disorientation Test (GDT). Associations were assessed using Spearman rank correlation, and multivariable regression analyses. For correlation analyses, DSST correlated to RALP/LARP tilt, roll tilt, and z-translation. TMT-A only correlated to z-translation, and TMT-B correlated to roll tilt and z-translation after correcting for multiple comparisons. GDT correlated to RALP/LARP tilt and y-translation. In age-adjusted regression analyses, DSST and TMT-B were associated with z-translation thresholds and GDT was associated with y-translation thresholds. In this cross-sectional study, we identified associations between vestibular perceptual thresholds with otolith contributions and standard measures of cognition. These results are in line with past results suggesting unique associations between otolith function and cognitive performance.

Challenges to School Success Among Children in U.S. Military Families

ABSTRACT Introduction More than 90% of children in military families attend civilian schools that may lack understanding of the unique experiences and stressors of military life. School success in children of military families has important implications on future academic achievement, health outcomes, and military groups; yet there has not been an examination of challenges of school success among children of military families in the United States using nationally representative data. Materials and Methods Data captured in the 2021-2022 National Survey of Children’s Health, limited to children aged 6 to 17 years, were used to examine the association between child’s caregiver military status and challenges of school success: lack of school engagement measured through caring about school and completing schoolwork, school absenteeism, and grade repetition (n = 60,599). Weighted to be nationally representative, bivariate analyses used chi-squared tests to examine estimates between selected variables and caregiver military status. Multivariable regression analyses were used to examine the association between caregiver military status and challenges of school success measures. Results In both unadjusted and adjusted analyses, we found that children of military families were more likely to not be engaged in school (adjusted odds ratios 1.35; 95% CI 1.19–1.53) and more likely to repeat a grade (adjusted odds ratios 1.33; 95% CI 1.09–1.64) than their civilian counterparts. There were no statistically significant differences in school absenteeism between children of military families and of civilian families. Conclusions This study extends beyond previous research findings that have focused primarily on academic achievement by including school engagement, attendance, and grade repetition for a more holistic and complete understanding of school success of children in military families. Our findings can be informational for school systems and policymakers to create educational and connective interventions for children in military families to improve school success.

Recurrent Hospitalizations for Fluid Overload in Diabetes with Kidney Failure Treated with Dialysis

Background & Aims Diabetes Mellitus is the most common cause of end-stage kidney disease (ESKD) in Singapore. ESKD patients have high disease burden and are at increased risk of recurrent hospitalizations, including fluid overload. This study aimed to characterize the risk factors associated with readmissions for fluid overload that will identify high-risk hospitalizations for interventions to reduce readmissions. Methods Retrospective cohort study of all hospitalizations for fluid overload in adults with diabetes and ESKD on dialysis in SingHealth hospitals between 2018 and 2021. Fluid overload was defined by discharge codes for fluid overload, heart failure, pulmonary edema, and generalized edema until 30th December 2022. Multivariable Cox regression analysis using the Prentice, Williams and Peterson Total Time (PWP-TT) model was performed for the outcomes of readmissions for fluid overload within 30 days and 90 days of discharge. Results Among 3234 hospitalizations for fluid overload, readmission for fluid overload within 30-day and 90-day occurred in 585 (18.1%) and 967 (29.9%) hospitalizations, respectively. Ischemic heart disease, peripheral vascular disease and lower hemoglobin level were independently associated with readmissions for fluid overload within 30 and 90 days. Additionally, heart failure, hemodialysis (compared to peritoneal dialysis) and lack of statin at discharge were associated with increased 90-day readmission risk. Conclusion Modifiable (hemoglobin level, statin use) and non-modifiable factors (ischemic heart disease, peripheral vascular disease and heart failure) influenced the risk of readmission for fluid overload. These results may guide risk stratification and inform targeted interventions to reduce avoidable, unplanned readmissions for recurrent fluid overload among individuals with diabetes and ESKD.

Assessing the validity of METS-IR for predicting the future onset of diabetes: an analysis using time-dependent receiver operating characteristics.

The Metabolic Insulin Resistance Score (METS-IR) is a non-invasive proxy for insulin resistance (IR) that has been newly developed in recent years and has been shown to be associated with diabetes risk. Our aim was to assess the predictive value of METS-IR for the future development of diabetes and its temporal differences in people of different sex, age, and body mass index (BMI). The current study included 15,453 baseline non-diabetic subjects in the NAGALA cohort and then grouped according to the World Health Organization's (WHO) recommended criteria for age and BMI. Multivariate Cox regression and time-dependent receiver operator characteristics (ROC) curves were used to analyze the value of METS-IR in assessing and predicting the risk of diabetes in people of different sexes, ages, and BMIs. 373 individuals developed diabetes during the observation period. By multivariate COX regression analysis, the development of future diabetes was significantly associated with increased METS-IR, and this positive association was stronger in women than in men and in individuals < 45 years than in individuals ≥ 45 years; while no significant differences were observed between non-obese and overweight/obesity individuals. Using time-dependent ROC analysis we also assessed the predictive value of METS-IR for future diabetes at a total of 11-time points between 2 and 12 years. The results showed that METS-IR had a higher predictive value for the future development of diabetes in women or individuals < 45 years of age compared to men or individuals ≥ 45 years of age for almost the entire follow-up period. Furthermore, across different BMI categories, we also found that in the short term (3-5 years), METS-IR had a higher predictive value for the development of diabetes in individuals with overweight/obesity, while in the medium to long term (6-12 years), METS-IR was more accurate in predicting the development of diabetes in non-obese individuals. Our study showed that METS-IR was independently associated with the development of future diabetes in a non-diabetic population. METS-IR was a good predictor of diabetes, especially for women and individuals < 45 years old for predicting the future risk of developing diabetes at all times.

Association Between Direct Oral Anticoagulant Score and Bleeding Events in Patients With Atrial Fibrillation Following Transcatheter Aortic Valve Replacement: A Retrospective Multicenter Cohort Study.

The Direct Oral Anticoagulant (DOAC) Score can predict bleeding risk in patients with atrial fibrillation taking DOACs; however, it lacks external validation. Therefore, this study aimed to assess the association between the DOAC Score and bleeding events in patients with atrial fibrillation who underwent transcatheter aortic valve replacement. This retrospective multicenter cohort study included patients with atrial fibrillation who underwent transcatheter aortic valve replacement, as registered in a Japanese multicenter registry. The primary end point was the incidence of bleeding. Patients were categorized based on their DOAC Score: low and moderate- (≤7 points), high- (8-9 points), and very high-risk (≥10 points) groups. Among 1230 patients (mean age 84.6±5.1 years; 457 men), 465 (37.8%) received a vitamin K antagonist, and the remaining patients received DOACs. The low and moderate-, high-, and very high-risk groups included 380 (30.1%), 497 (40.4%), and 353 patients (28.7%), respectively. The 3-year cumulative incidence of all bleeding events was significantly different among the 3 groups (low and moderate risk: 6.6%, high risk: 6.9%, and very high risk: 14.0%; P<0.01). Multivariable Cox regression analysis revealed that significant increments in the DOAC Score were associated with a risk of all bleeding events at 3 years in the overall cohort (hazard ratio [HR], 1.22 [95% CI, 1.08-1.38]; P<0.01), in the DOAC cohort (HR, 1.20 [95% CI, 1.01-1.42]; P=0.04), and in the vitamin K antagonist cohort (HR, 1.25 [95% CI, 1.04-1.50]; P=0.02). The DOAC Score was significantly associated with bleeding events in patients with atrial fibrillation after transcatheter aortic valve replacement, aiding in clinical decision-making for anticoagulant management.

Reliability and validity of the Turkish form of intensive care nursing activities score.

The purpose of this study was to examine the reliability and validity of the Turkish version of the Nursing Activities Score. To validate the Turkish version of the Nursing Activities Score, a sample comprising 30 adult intensive care patients and 30 nurses was employed. After a pilot study, the internal consistency, Cronbach's alpha coefficient, was found to be p = 0.718. Following the significant internal consistency obtained in the pilot study, the correlation between Nursing Activities Score internal consistency and Critical Nursing Situation Index scores was examined in 150 adult intensive care patients and 150 nurses. The assessment of inter-rater reliability showed a high level of agreement (99%) and an average Kappa index of 0.598 (p < 0.001). Concurrent validity was demonstrated through a statistically significant correlation between Nursing Activities Score and the Critical Nursing Situation Index (r = 0.71, p < 0.001) and multivariate regression analysis (R2 = 83%, p < 0.001). The validity is supported by the statistically significant relationship between Nursing Activities Score and Critical Nursing Situation Index. These results demonstrate that Nursing Activities Score is a valid and reliable tool for measuring nursing workload in Turkish intensive care units.

The Effect of L5 Morphology on Prevention of L5-S1 Degeneration Following Floating Fusion for Degenerative Spine Disorders.

Retrospective Study. The selection of floating fusion or lumbosacral fusion arises when treating patients with instability or stenosis of the lower lumbar spine concomitantly radiographic degeneration of L5-S1. This study aimed to investigate the preoperative anatomical or morphological factors affecting the survivorship of the L5-S1 after floating fusion. This study included 77 patients who had undergone floating fusion surgery through the TLIF approach. Preoperative radiographic parameters were evaluated using anteroposterior and lateral lumbar spine radiographs. The patients were divided into two groups according to the Modified Pfirrmann Grading and total endplate score. Multivariable regression analysis was performed to explore the relationships between the anatomical or morphological characteristics of L5 and the degeneration of L5-S1. The disc degeneration group exhibited a smaller height ratio of the iliac crest (Hi) and a less L5 deep position. Furthermore, the right/left height of L4 (Hr/Hl) and the right/left width of transverse process of L5 (CRt/CLt) were significantly higher in the disc and endplate degeneration groups. Multiple logistic regression analysis revealed that Hi and CRt were independently associated with L5-S1 disc degeneration, whereas Hr was a significant risk factor for L5-S1 endplate degeneration. Anatomical and morphological characteristics of L5, such as smaller Hi, higher CRt and Hr, were associated with an increased risk of L5-S1 degeneration in patients after floating fusion. These findings may indicate the fusion level when addressing lower lumbar degenerative diseases and the concurrent radiographic degeneration of L5-S1.

Background: Comorbidities that help predict poor outcomes in patients with acute ischemic stroke play a part in treatment planning and provide necessary information for patients and their families. Objective: Identify comorbidities that can predict poor outcomes 90 days after the onset of acute ischemic stroke. Subjects and methods: Prospective study including 150 acute ischemic stroke patients at Trieu An Hospital, Ho Chi Minh City. Subjects recruited upon admission were collected NIHSS score and comorbidities. Subjects had modified Rankin scores collected 90 days after disease onset. Univariate analysis and multivariate regression analysis were used to determine the role of variables on stroke outcomes. Results: The mean age was 65, male accounts for 62.0%. There were 8 factors univariately associated with poor outcome after 90 days of acute ischemic stroke onset: NIHSS, age, atrial fibrillation, valvular heart disease, coronary artery disease, heart failure, extracranial atherosclerosis and dementia. Among them, dementia is an independent prognostic factor for poor outcomes through multivariate analysis. The number of comorbidities is closely related to poor outcomes, the number of comorbidities ≥ 3 predicts patients with poor outcomes after 90 days of disease onset with a sensitivity of 96.6%; Specificity was 88.0%; The area under the curve was 96.3%. Conclusion: In acute ischemic stroke patients with comorbidities ≥ 3, the patient's prognosis is poor. In addition, dementia is an independent prognostic factor of poor outcome after 90 days from disease onset.

Predictive value of pre-treatment circulating tumor DNA genomic landscape in patients with relapsed/refractory multiple myeloma undergoing anti-BCMA CAR-T therapy: Insights from tumor cells and T cells.

B-cell maturation antigen (BCMA)-directed chimeric antigen receptor T (CAR-T) therapy yield remarkable responses in patients with relapsed/refractory multiple myeloma (R/RMM). Circulating tumor DNA (ctDNA) reportedly exhibits distinct advantages in addressing the challenges posed by tumor heterogeneity in the distribution and genetic variations in R/RMM. Herein, the ctDNA of 108 peripheral blood plasma samples from patients with R/RMM was thoroughly investigated before administration of anti-BCMA CAR-T therapy to establish its predictive potential. Flow cytometry is used primarily to detect subgroups of T cells or CAR-T cells. In this study, several tumor and T cell effector-mediated factors were considered to be related to treatment failure by an integrat analysis, including higher percentages of multiple myeloma (MM) cells in the bone marrow (P=0.013), lower percentages of CAR-T cells in the peripheral blood at peak (P=0.037), and higher percentages of CD8+ T cells (P=0.034). Furthermore, there is a substantial correlation between high ctDNA level (>143ng/mL) and shorter progression-free survival (PFS) (P=0.007). Multivariate Cox regression analysis showed that high levels of ctDNA (>143ng/mL), MM-driven high-risk mutations (including IGLL5 [P=0.004], IRF4 [P=0.024], and CREBBP [P=0.041]), number of multisite mutations, and resistance-related mutation (ERBB4, P=0.040) were independent risk factors for PFS. Finally, a ctDNA-based risk model was built based on the above independent risk factors, which serves as an adjunct non-invasive measure of substantial tumor burden and a prognostic genetic feature that can assist in predicting the response to anti-BCMA CAR-T therapy.

BCAA was more closely associated with visceral fat area than subcutaneous fat area in patients of type 2 diabetes mellitus: a cross-sectional study

BackgroundBranched-chain amino acid (BCAA) has been reported to be associated with obesity, the association of BCAA with visceral fat area (VFA) and subcutaneous fat area (SFA) remained unclear in patients with type 2 diabetes.MethodsThis cross-sectional study was conducted in 284 patients with type 2 diabetes mellitus. Enzyme-linked immunospecific assay was used to measure levels of serum BCAA and branched-chain keto acid (BCKA). VFA and SFA were measured with bio-impedance analysis method. The association between BCAA and VFA was calculated using Pearson correlation and multivariable linear regression analysis.ResultsThere were significant differences in the means of body mass index, waist circumstance, SFA and VFA among the three groups divided by total BCAA tertiles (all p < 0.05). Compared to patients with lower levels of serum BCAA (the lower tertile group), the means of VFA and SFA were significantly larger in the middle and upper tertile groups (all p < 0.05). However, the differences in above obesity parameters were nonsignificant according to various BCKA tertiles. Pearson correlation analysis also demonstrated that BCAA levels were positive associated with each obesity parameter (p < 0.05). Nevertheless, multivariable linear regression analysis showed that levels of serum BCAA were correlated with VFA, BMI and WC (all p < 0.05) rather than SFA after adjusted for other confounders.Conclusionslevels of serum BCAA were more closely correlated with VFA than SFA, prospective studies should be warranted to further explore the mechanism mediating BCAA and visceral fat accumulation in Human beings.Clinical trial numberNot applicable.

Energy in the workplace: job demands, job resources, and employees’ inner resources as pathways to organizational outcomes

In this study, we expanded upon the job demands–resources model to assess the role of employees’ vitality as an inner resource for their work engagement and job commitment. To assess vitality and related job resources, we developed an index of vitality outside of work and adapted measures of manager autonomy support and organizational support. For job demands, we measured work stress and predicted that each of these four variables would contribute independently to work-related outcomes. Then, in a preregistered study, we collected these measures from a sample of 5,280 American workers (primarily ages 18–34, 54% female). Results from multivariate regression analyses largely confirmed our hypotheses, showing that positive work-related outcomes, such as enthusiasm, enjoyment, and job satisfaction, were positively predicted by manager autonomy supports, organizational support, and individuals’ vitality, and negatively predicted by work stress. The reverse pattern was largely observed for the negative outcome of turnover intention. Exploratory analyses also suggested that individual vitality may buffer the negative effects of stress and low manager and organizational support. The results highlight the potential role of employee vitality outside of work and managerial support in bolstering work engagement and reducing turnover intentions, offering a basis for organizational strategies aimed at improving work culture and retaining talent.

Image Features and Diagnostic Value of Contrast-Enhanced Ultrasound for Ductal Carcinoma In Situ of the Breast: Preliminary Findings.

To explore the image features and the diagnostic value of contrast-enhanced ultrasound (CEUS) for ductal carcinoma in situ (DCIS) of the breast. A total of 96 female patients with a solitary and histologically proven DCIS were analyzed retrospectively, and 100 female cases of invasive ductal carcinoma (IDC) lesions were used as the control group. The Breast Imaging Reporting and Data System (BI-RADS) category of breast lesions was assessed according to conventional ultrasound features. The DCIS lesions were classified into mass type and non-mass type. The CEUS characteristics of these breast lesions were retrospectively analyzed qualitatively and quantitatively. The final gold standard was biopsy or surgery with histo-pathological examination. Comparing the ultrasound images of DCIS with that of IDC, there were significant differences in echo pattern, calcification morphology, and calcification distribution (p < .05 for all). There was a significant difference between DCIS and IDC in enhancement intensity, perfusion defects, peripheral high enhancement, intratumoral vessels, and arrival time (AT) (p < .05 for all). In the logistic multivariate regression analysis, two indicators linked with DCIS were recognized: perfusion defects (p = .002) and peripheral high enhancement (p < .001). In forecasting DCIS, the logistic regression equation resulted in an AUC of 0.689, a specificity of 0.720, and a sensitivity of 0.563. CEUS showed differences in enhancement characteristics between DCIS and IDC, with perfusion defects and peripheral high enhancement being associated with DCIS.

Risk factors for puncture-related complications after cerebrovascular angiography and neuroendovascular intervention with distal transradial approach.

To determine the risk factors for puncture-related complications after the distal transradial approach (dTRA) for cerebrovascular angiography and neuroendovascular intervention and to explore the incidence and potential mechanisms of procedural failure and puncture-related complications. From February to November 2023, 62 patients underwent dTRA in our department. Demographic, clinical, and procedural data were collected retrospectively. Postoperative puncture-related complications were defined as a syndrome of major hematoma, minor hematoma, arterial spasm/occlusion, arteriovenous fistula, pseudoaneurysm, and neuropathy. Univariate and multivariate logistic regressions were performed to identify significant factors contributing to puncture-related complications. Forty-five diagnostic cerebral angiograms and 17 neurointerventions were performed or attempted with dTRA in 62 patients. Procedural success was achieved via dTRA in 47 (75.8%) patients, whereas 15 (24.2%) required conversion to other approaches. Reasons for failure included puncture failure (n = 8), inability to cannulate due to arterial spasm (n = 6), and inadequate catheter support of the left vertebral artery (n = 1). 17.0% (8/47) of patients had postoperative puncture-related complications. Minor hematoma occurred in 8.5% (4/47) of patients, arterial spasm/occlusion in 6.3% (3/47), and neuropathy in 2.1% (1/47). No major complications were observed. On stepwise multivariable regression analysis, BMI (OR = 0.70, 95%CI 0.513 to 0.958; p = 0.026) was an independent risk factor for puncture-related complications, with a cut-off of 24.8kg/m2 (sensitivity 66.7% and specificity 87.5%). Our cohort is the first study of risk factors for puncture-related complications after neurointerventional interventions with dTRA. This study has shown that a low BMI (< 24.8kg/m2) is independently associated with the development of puncture-related complications.

Impact of Knee Osteoarthritis and Arthroplasty on Full Body Sagittal Alignment in Adult Spinal Deformity Patients.

Retrospective analysis of prospectively collected data. This study evaluates the impact of knee osteoarthritis (OA) and knee arthroplasty on alignments and patient-reported outcomes measures (PROMS) of patients undergoing adult spinal deformity (ASD) corrective surgery. The relationship between knee OA and spinal alignment in patients with ASD is incompletely understood. It is also unknown how patients with knee arthroplasty and ASD compare to ASD patients with native knees. Baseline full-body radiographs were used, and hip and knee OA were graded by two independent reviewers using the KL classification. Spinopelvic parameters and PROMs were compared across the different knee OA groups and compared between patients with knee replacement and native knees. 199 patients with bilateral non severe OA (G1), 31 patients with unilateral severe knee OA (G2), and 60 patients with bilateral severe knee OA (G3). Patients with severe knee OA presented with worse spinopelvic parameters. However, after multivariable regression analysis controlling for age, frailty, PI, T1PA, knee OA was an independent predictor of knee flexion (G1:-0.02±7.3, G2: 7.8±9.4, G3: 4.5±8.7, P<0.001), and ankle dorsiflexion (G1: 2.3±4.0, G2: 6.6±4.5, G3: 5.1±4.1, P<0.001). There was no difference in PROMs (P>0.05). Secondary analysis included 96 patients: 48 patients (50%) with non-severe knee OA, and 48 patients (50%) with knee replacement. There was no difference in radiographic parameters or PROMs between the groups. In this study of complex ASD patients, patients with worse spinal deformity were more likely to have concomitant knee OA. Knee OA was shown to be a predictor of knee flexion and ankle dorsiflexion angles, but was not associated with worse PROMs in this study population. Patients with knee arthroplasty, however, had comparable spinal alignment and PROMs relative to those with mild OA.

Development of prediction models for carbapenem-resistant Klebsiella pneumoniae acquisition and prognosis in adult patients

ObjectivesTo explore the risk factors and clinical outcomes of carbapenem-resistant Klebsiella pneumoniae (CRKP) infection and establish nomograms to predict the probability of CRKP infection and mortality in adult patients.MethodsPatients infected with KP from August 2019 to April 2021 in a tertiary hospital in Shanghai were enrolled. Risk factors associated with CRKP and 30-day mortality were identified using multivariate logistic regression analysis and Cox regression analysis.ResultsOverall, 467 patients with KP infection were enrolled, wherein 210 (45.0%) patients were infected with CRKP and 257 (55.0%) patients with carbapenem-susceptible K. pneumoniae (CSKP). Five factors, namely Charlson’s Comorbidity Index (CCI) ≥ 3, the use of central venous catheterization, prior hospitalization during the 3 months before infection, and previous exposure to carbapenems and broad-spectrum β-lactams, were found to be independently associated with CRKP infection. Based on these parameters, the nomogram showed a better performance as indicated by C-index of 0.94 (95% confidence interval [CI]: 0.92–0.96) and well-fitted calibration curves. CRKP was independently associated with 30-day mortality. Multivariate Cox regression analysis revealed that age ≥65 years, higher CCI scores, higher Sequential Organ Failure Assessment scores, the presence of respiratory failure, albumin levels ≤30 g/L, and non-appropriate treatments in 3 days, were associated with 30-day mortality.ConclusionThe predictive nomogram established in this study can facilitate the clinicians to make better clinical decisions when treating patients with KP infection.

Preoperative red cell distribution width and its relation with in-hospital morbidities including atrial fibrillation after coronary artery bypass

Background and Aims: Atrial fibrillation (AF) and other adverse events are significant concerns following coronary artery bypass grafting (CABG). In recent years, Red Cell Distribution Width (RDW) has been identified as a potential biomarker for predicting these adverse outcomes. This study aims to assess early in-hospital adverse events in patients undergoing isolated off-pump CABG (OPCAB) and to analyze the relationship between these events and preoperative RDW levels. Methods: This study prospectively included 150 patients who underwent elective isolated OPCAB procedures. Patients were categorized into an “event group” (those experiencing adverse events) and a “no-event group” (those who did not). Additionally, they were stratified according to preoperative RDW levels into three groups: Group A (RDW ≤14%), Group B (RDW 14-16%), and Group C (RDW ≥16%). A receiver operating characteristic (ROC) curve, followed by both univariate and multivariate regression analyses were utilized to evaluate the predictive value of RDW for in-hospital morbidity. Results: The in-hospital mortality rate was 2.7%, and AF occurred in 20.7% of the patient population. The ROC analysis for early adverse events yielded an Area Under the Curve (AUC) of 0.681 with a p-value &lt;0.001, indicating moderate predictive capability; the sensitivity was 73% and specificity was 64% for RDW ≥14.05%. Multivariate regression analysis demonstrated that RDW independently predicts in-hospital morbidity after OPCAB, with an odds ratio of 0.713 (95% CI 0.566-0.899, p=0.004). Conclusion: Elevated preoperative RDW levels serve as a simple and cost-effective independent predictor of early adverse events following isolated OPCAB.

Protective effects of long term antiplatelet and anticoagulant therapy in hospitalized patients with inflammatory bowel disease

BACKGROUND Inflammatory bowel disease (IBD), with its rising prevalence rates is associated with an increased risk of cardiovascular and thromboembolic events. Antiplatelets and/or anticoagulants agents are often prescribed but the literature on the impact of long-term anticoagulation and/or antiplatelet use among patients hospitalized with IBD is scarce. The aim of this study is to assess the outcomes of patients hospitalized with IBD on antiplatelet and/or anticoagulant agents. AIM To investigate the effects of long-term use of antiplatelets/anticoagulants on clinical outcomes in patients hospitalized with IBD. METHODS We conducted a retrospective cohort study using the Nationwide Inpatient Sample database, including all adult IBD patients hospitalized in the United States from 2016 to 2019. Patient cohorts were stratified based on antiplatelet/anticoagulant therapy status. Multivariate regression analysis was done to assess outcomes, adjusting for potential confounders. The primary outcome was mortality, whereas length of stay (LOS), total parenteral nutrition, acute kidney injury, sepsis, shock, gastrointestinal bleeding, need for colonoscopy/sigmoidoscopy, abdominal surgery and total hospitalization charges were secondary outcomes. RESULTS Among 374744 hospitalized IBD patients, antiplatelet or anticoagulant therapy alone was associated with significantly lower in-hospital mortality and reduced healthcare utilization, including shorter LOS and decreased hospitalization costs. Combined therapy was associated with a protective effect on mortality, but did not reach statistical significance. Notably, therapy did not exacerbate disease severity or complications, although higher odds of gastrointestinal bleeding were observed. CONCLUSION Our study highlights the potential benefits of long-term anticoagulation/antiplatelet therapy in hospitalized IBD patients, with improved mortality outcomes and healthcare utilization. While concerns regarding gastrointestinal bleeding exist, the overall safety profile suggests a role for these agents in mitigating thromboembolic risks without exacerbating disease severity. Further research is needed to look at optimal treatment strategies and addressing limitations to guide clinical decision-making in this population.
