Association between behavioral patterns and depression symptoms: dyadic interaction between couples.

Behavioral patterns are sometimes associated with depression symptoms; however, few studies have considered the intra-couple effects. This study examined the effect of a spouses' behavioral patterns on depression symptoms within themself and in their spouse. A total of 61,118 childbearing age participants (30,559 husband-wife dyads) were surveyed. The depression symptoms were assessed using the nine-item Patient Health Questionnaire (PHQ-9). The behavioral patterns were identified by the latent class analysis. The effects of behavioral patterns on the couple's own depression symptoms (actor effect) and their partner's depression symptoms (partner effect) were analyzed using the Actor-Partner Interdependence Model (APIM). Three behavioral patterns were identified: low-risk group, moderate-risk group, and high-risk group. The high risk of these behavior patterns would be associated with a higher score on the PHQ-9; for both husbands and wives, their behavioral patterns were positively associated with PHQ-9 scores (βhusband = 0.53, P < 0.01; βwife = 0.58, P < 0.01). Wives' behavioral patterns were also positively associated with their husbands' PHQ-9 scores (β = 0.14, P < 0.01), but husbands' behavioral patterns were not associated with their wives' PHQ-9 scores. Wives' depression symptoms were affected only by their own behavioral patterns, whereas husbands' depression symptoms were influenced by both their own and their spouses' behavioral patterns.

Diagnostic and Predictive Value of Brachial–Ankle Pulse Wave Velocity and Pulse Pressure Index for Coronary Heart Disease in Elderly Patients With Hypertension

Abstract OBJECTIVE To explore the diagnostic and predictive value of pulse pressure index (PPI) and brachial–ankle pulse wave velocity (baPWV) for coronary heart disease (CHD) in elderly patients with hypertension. METHODS A total of 307 elderly patients who had chest pain or chest distress and coronary angiography were enrolled. According to the Gensini score, patients with CHD (n = 260) were divided into low-risk group (&amp;lt;20 points, n = 96), moderate-risk group (20–40 points, n = 80), and high-risk group (&amp;gt;40 points, n = 84). baPWV was measured using an ankle–brachial index and pulse wave measuring device. Multivariate logistic regression analysis was used to analyze the risk factors of CHD. Receiver operating characteristic (ROC) curve was used to evaluate the diagnostic value of baPWV and PPI for CHD. RESULTS PPI and baPWV of elderly hypertensive patients with CHD at low, moderate, and high risk were higher than those without CHD [PPI: 0.43 ± 0.04, 0.45 ± 0.04, 0.45 ± 0.05 vs. 0.41 ± 0.05, F = 31.768, P &amp;lt; 0.001; baWV: 1,671 (1,587–1,755), 1,717 (1,597–1,843), 1,780 (1,661–1,960) vs. 1,570 (1,477–1,699) cm/s, X2 = 60.918, P &amp;lt; 0.001]. With the increase in CHD severity, the PPI and baPWV were significantly increased (P &amp;lt; 0.05). Spearman/Pearson correlation analysis showed that the Gensini score was positively correlated with baPWV and PPI, respectively (both P &amp;lt; 0.001). Multivariate logistic regression analysis showed that baPWV, PPI, and systolic blood pressure were the influencing factors of CHD in hypertensive patients. The areas under the ROC curve (95% CI) of baPWV, PPI, and their combination for diagnosing CHD were 0.792 (0.723–0.861), 0.708 (0.625–0.792), and 0.837 (0.779–0.895), respectively, and was significantly different between baPWV or PPI alone and the combination of the 2 (Z = −2.178, P = 0.029; Z = −3.330, P = 0.001). CONCLUSIONS Elevations of baPWV and PPI are positively correlated with the severity of CHD. Both baPWV and PPI have a diagnostic and predictive value for CHD in elderly hypertensive patients, and the combination of baPWV and PPI is more accurate.

The Relationship Between Echocardiographic Calcification Score and Grade of Knee Osteoarthritis.

Background and objective It has been suggested that knee osteoarthritis (KOA) is associated with the development of calcification and an increased risk of cardiovascular (CV) disease, while the contribution of KOA grade is not clearly known enough. This study aimed to investigate the relationship between the grade of KOA, the echocardiographic calcification score (echo-CCS), and CV risk assessment. Methods This cross-sectional study involved 204 patients diagnosed with KOA and classified according to the Kellgren-Lawrence staging criteria. Echo-CCS was obtained according to the presence of calcification in the aortic valve, aortic root, mitral ring, papillary muscle and ventricular septum. Framingham risk score (FRS) was used for CV risk assessment. Results Calcification was detected in 79.4% of patients. The median FRS, echo-CCS, andhigh-sensitivityC-reactive protein (hs-CRP) levels increased as the KOA grade increased (p<0.05). A one-grade increase in KOA increased the odds of echo-CCS 1-2 group by 5.15 fold (vs. no calcification group) (OR=5.15, p=0.003), while it increased the odds of echo-CCS ≥3 group by 4.61 fold (vs. echo-CCS 1-2 group) (OR=4.61, p=0.003). Median echo-CSS and hs-CRP were higher in the high CV risk group than in the moderate and low CV risk groups. Conclusion The majority of patients with KOA had intracardiac calcification.An increased KOA grade was associated with higher echo-CSS and FRS. These findings indicate that patients with higher grades of KOA may be predisposed to developing subclinical atherosclerosis.

Echocardiographic features predict the performance of transthoracic echocardiography in ruling out infective endocarditis: a 5-year study

Abstract Background Transoesophageal echocardiography (TOE) remains the gold standard imaging modality to aid in the diagnosis of infective endocarditis (IE), but is resource intensive and confers patient risk. Transthoracic echocardiography (TTE) is a more accessible alternative, but previous studies report varying ability of TTE to effectively rule out disease. As a result, negative TTE is often still followed with TOE when clinical suspicion remains. However, these studies did not account for TTE quality and other echocardiographic features within the TTE that may decrease its diagnostic utility and thereby reduce its ability to effectively rule out disease. Understanding the risk of missing IE for a given negative TTE could avoid the need for subsequent TOE. Purpose Our aim is to devise and test the validity of a scoring system which can stratify TTEs by quality to predict TTE performance and inform the decision for whether follow-up TOE is necessary. Methods In this retrospective single-centre study, the Predictor of TTE Performance (PTP) scoring system was developed and applied to patients undergoing both TTE and TOE for suspected IE at our tertiary centre between May 2017 and May 2022. Within the scoring system, a point was allocated for the presence of each of the following on TTE: a mobile echodensity; poor image quality; more than mild regurgitation; a prosthetic valve or prosthetic intracardiac material; and other valvular abnormalities. Poor image quality was defined as any TTE that was unable to achieve good endocardial visualisation from at least two views. Valvular abnormalities warranting a point included congenital abnormalities such as bicuspid aortic valve and acquired abnormalities such as rheumatic valvular disease, mitral valve prolapse and valvular stenosis. The negative predictive value (NPV) for TTEs in each score category was analysed using TOE as the gold standard. Results A total of 362 patients with paired TTE/TOE were included for analysis. 60 (16.6%) had positive TOE, with the overall NPV of TTE being 88.5% (95% CI: 84.6–91.5%). Using the PTP scoring system, patients were stratified into low-risk (score of 0, n = 116), moderate-risk (score of 1, n = 140) and high-risk (score greater than 1, n = 106) groups. Increasing PTP score was associated with poorer TTE performance, with the low-risk, moderate-risk and high-risk categories having NPVs of 98.3% (95% CI: 93.9–99.7%), 90.2% (95% CI: 83.9–94.2%) and 72.3% (95% CI: 61.8–80.8%) respectively. Conclusion The ability of TTE to exclude IE is excellent when patients have no echocardiographic features that reduce TTE quality or predict increased risk for endocarditis. In patients with a low PTP score, negative TTE may render follow-up TOE unnecessary.

Risk differences between atrial fibrillation patients with different clinical phenotypes: insights from the French population

Abstract Background Atrial fibrillation (AF) patients represent a clinically complex, heterogeneous population comprising multiple homogeneous cohorts. Purpose We aimed to identify the common clinical phenotypes of AF patients and compare clinical outcomes between these subgroups. Methods A 1% representative sample of all AF patients hospitalized between 2010 and 2019 was identified from the French national database. Agglomerative hierarchical cluster analysis was performed using Ward’s method and squared Euclidian distance , to derive 4 distinct clusters of patients (Figure 1) using 31 clinical variables. Cox regression analyses were used to evaluate outcomes including all-cause death, cardiovascular death, non-cardiovascular death, ischaemic stroke, hospitalisation for heart failure (HF) and composite of ventricular tachycardia, ventricular fibrillation and cardiac arrest (VT/VF/CA). Results Four clusters were generated from the 12,688 patients included. Cluster 1 (n=2375) was younger, with a low risk of cardiovascular disease (CVD) and risk factors such as hypertension, dyslipidaemia and diabetes, but had the highest cancer prevalence. Clusters 2 (n=6441) and 3 (n=1639) depicted moderate-risk groups for CVD, with the female majority and high rates of lung conditions being the distinct features respectively. Cluster 3 also had the highest degree of frailty, with clusters 2 and 4 following closely. Cluster 4 (n=2233) represented a high-risk cohort for CVD with a high prevalence of coronary artery and vascular disease. Over a follow-up period of 2.0±2.3 years (median 1.1, interquartile range 0.1-3.4), cluster 3 had the highest cumulative incidence of all outcomes except for cardiovascular death which was highest in cluster 4. Compared to cluster 1, cluster 3 had the highest risk for all-cause death, HR 1.24 (1.09-1.41), cardiovascular death, HR 1.56 (1.19-2.06), non-cardiovascular death, HR 1.20 (1.04-1.38), hospitalisation for HF, HR 2.07 (1.71-2.50) and VT/VF/CA, HR 1.74 (1.20-2.53). Conclusion Four main clusters of AF patients were identified, discriminated by the differential presence of comorbidities. Our findings suggest that AF patients with moderate CVD-risk may have a poorer prognosis compared to AF patients with high CVD-risk in the presence of lung pathology. Therefore, this subgroup of patients may require more stringent management of existing comorbidities such as chronic obstructive pulmonary disease and sleep apnoea, alongside their AF.

Eveningness is associated with coronary artery calcification in a middle-aged Swedish population

Coronary artery calcification (CAC) is an established imaging biomarker of subclinical atherosclerosis, but its relationship to diurnal preference is not well studied. We investigated the association between chronotype and CAC in the Swedish CArdioPulmonary bioImage Study (SCAPIS) pilot cohort. Participants aged 50–64 years were randomly recruited and underwent extensive examination including imaging and accelerometry-assessed physical activity. 771 participants (47.3 % male, 57.6 ± 4.4 years) were included in this cross-sectional analysis. CAC was assessed by non-contrast computed tomography, and a CAC score > 10 was considered significant calcification. Self-assessed chronotype was classified as extreme morning, moderate morning, intermediate, moderate evening, or extreme evening. 10-year risk of first-onset cardiovascular disease was estimated by the Systemic Coronary Risk Evaluation 2 (SCORE2). Significant CAC was present in 29 % of the cohort. CAC prevalence increased from extreme morning to extreme evening type (22 %, 28 %, 29 %, 27 %, 41 % respectively, p = 0.018). In a multivariate logistic regression model controlling for confounders, extreme evening chronotype was independently associated with increased CAC prevalence compared to extreme morning type (OR 1.90, [95%CI 1.04–3.46], p = 0.037). When stratified by SCORE2 risk category (low: <5 %; moderate: 5 to <10 %; high: ≥10 %), significant CAC was most prevalent among extreme evening chronotypes in the low and moderate-risk groups, while chronotype seemed less important in the high-risk group (p = 0.011, p = 0.023, p = 0.86, respectively). Our findings suggest circadian factors may play an important role in atherosclerosis and should be considered in early cardiovascular prevention.

Abstract 12849: Assessing Cardiovascular Toxicity in Cancer Treatment: Validation of the Heart Failure Association and International Cardio-Oncology Society Tool Using Prospective Registry Data

Introduction: Cancer treatment-related cardiovascular toxicity (CTR-CVT) is a growing concern in patients undergoing anticancer therapy. The Heart Failure Association (HFA) and International Cardio-Oncology Society (ICOS) risk assessment tools have been proposed for the baseline cardiovascular (CV) risk stratification of patients with cancer. This study examined the incidence of adverse CV events associated with cancer treatment in clinical practice, also using the HFA-ICOS risk assessment tool. Methods: This single-center, prospective, observational study was conducted at Kurume University Hospital between October 2016 and August 2021 in patients aged ≥20 years with hematologic malignancies or breast cancer who were receiving anticancer agents. CV assessments were performed at enrollment and every 6 months until February 2022, with additional assessments for suspected CV adverse events. The primary endpoint was adverse CV event as defined by Common Terminology Criteria for Adverse Events (CTCAE) v4.0 grade ≥2, and the secondary endpoints were all-cause and CV death. Results: Of the enrolled 486 patients, adverse CV events occurred in 24.5% of patients with leukemia, 15.8% of patients with malignant lymphoma, 38.1% of patients with multiple myeloma, and 18.0% of patients with breast cancer, respectively. Kaplan-Meier curves of the primary endpoint and heart failure (HF)/ left ventricular (LV) dysfunction stratified by HFA-ICOS risk assessment group have shown the significant worse events in high/very high-risk group, in which the hazard ratios in the high/very high-risk group compared to the low-risk group were 2.34 (95% CI 1.48-3.71, p&lt;0.001) in the primary endpoint and 3.57 (95% CI 1.70-7.51, p&lt;0.001) in HF/LV dysfunction. There was no significant difference in the event risk between the low- and moderate-risk groups. CV death occurred in 4 patients (0.8 %) during follow-up. Conclusions: This study showed that 16-38% of patients with hematologic malignancies and breast cancer developed CTR-CVT during follow-up, in which high/very high-risk patients were well predicted by the HFA-ICOS risk assessment tool. The monitoring and managing CV risk factors are essential for safe cancer therapy.

Abstract 17817: Deep Learning-Based Retinal Imaging for Predicting Cardiovascular Disease Events in Prediabetic and Diabetic Patients: A Study Using the UK Biobank

Introduction: Our previous work led to developing a deep learning algorithm for retinal images, Reti-CVD, which effectively predicted cardiovascular disease (CVD) events in individuals without CVD history, leveraging coronary artery calcium (CAC) scores for algorithm training. Hypothesis: This study aims to assess the capability of deep learning-assisted retinal imaging to predict CVD events among prediabetic and diabetic patients using the data from the UK Biobank. Methods: Our study included prediabetic and diabetic patients from the UK Biobank. Reti-CVD scores were calculated and categorized into three risk groups - low (n=550), moderate (n=276), and high (n=275), based on the 50th and 75th percentiles, following a 2:1:1 ratio. To assess the Reti-CVD's ability in predicting fatal and non-fatal CVD events, we performed a survival analysis on the longitudinal data from the UK Biobank using Cox proportional-hazards models and hazard ratios (HRs). Results: Among the 1101 prediabetic or diabetic patients at the onset, 138 (12.5%) experienced CVD events. According to Reti-CVD scores, these events were found as 8.2% (45/550), 15.2% (42/276), and 18.5% (51/275) in the low, moderate, and high-risk groups over a median follow-up period of 11 years, respectively. After adjusting for factors such as age, gender, hypertensive medication use, statin use, and smoking history, a significant association was observed between the Reti-CVD and the incidence of CVD events (HR=1.57, 95% CI, 1.00-2.47 for the moderate-risk group; HR=1.88, 95% CI, 1.19-2.98 for the high-risk group compared to the low-risk group). An increasing HR trend of 1.36 (95% CI, 1.09-1.70) was observed across risk groups in the prediction of CVD events. Conclusions: The Reti-CVD offers a valuable tool for risk stratification among prediabetic and diabetic patients, indicating its potential in managing these high-risk groups.

COVID-19: An evaluation of predictive scoring systems in South Africa

Background| The Coronavirus Disease 2019 (COVID-19) pandemic, caused by SARS-CoV-2, has resulted in more than 700 million cases worldwide. Sepsis and pneumonia severity scores assist in risk assessment of critical outcomes in patients with COVID-19. This allows healthcare workers to triage patients, by using clinical parameters and limited special investigations, thus offering the most appropriate level of care. Methods| A retrospective cohort study of 605 adult patients hospitalised with moderate to severe COVID-19, at a tertiary state hospital in South Africa. Evaluating the utility of the CURB65, NEWS2 and ISARIC-4C Mortality Score, in predicting critical outcomes, using clinical characteristics on admission. Outcomes included in-hospital mortality, invasive mechanical ventilation, and intensive care unit admission (ICU). Performance of severity scores and risk factors was assessed by area under the receiver operator characteristics (AUROC) analysis and logistic regression. Findings |A total of 605 records were used, 129 (21 %) non-survivors, 101 (17 %) ICU admissions and 77 (13 %) requiring invasive ventilation. Greater odds of mortality was associated with moderate and severe risk groups of the CURB65, ISARIC-4C and NEWS2 score. Mortality AUROC curve analysis for the CURB65 score was 0·76 (95 % CI: 0·71–0·8), 0·77 (95 % CI: 0·73–0·81) for the ISARIC-4C and 0·77 (95 % CI: 0·73–0·82) for the NEWS2 score. The CURB65 score had a sensitivity of 86 % with 12·8 % mortality, ISARIC-4C score a sensitivity of 87·6 % with 8 % mortality and NEWS2 score a sensitivity of 92·2 % with 8·6 % mortality. Interpretation |In 605 hospitalised patients with moderate to severe COVID-19, predominantly infected by the ancestral strain, good performance of the NEWS2 and ISARIC-4C score in predicting in-hospital mortality was noted. The CURB65 score had a high mortality rate in its low-risk group suggesting unexplained risk factors, not accounted for in the score, thus limiting its utility in the South African setting.

Reproducibility and content validity of the Slovenian version of the STarT Back Screening Tool for chronicity risk assessment in patients with low back pain.

Chronic pain is the most common cause of impaired work ability and thus represents a significant social and economic burden. STarT Back Screening Tool (SBT) is the most often used screening tool for rapid identification and classification of patients for their risk of development of chronic low back pain, which is valid and reliable in the original English version and translation into other languages. The aim of the present study was to translate the SBT into Slovenian and to evaluate its content validity and reliability. We translated the SBT from English into Slovenian and back according to the standard protocol. We tested its metric properties on a group of patients with low back pain aged 18 to 65 years. The reliability of the reassessment was calculated using the ICC and specific agreement, while the content validity of the questionnaire was determined using the ceiling and floor effect. Of the 42 patients who participated in the study, 42.9% were at low risk, 33.3% were at moderate risk, and 23.8% were at high risk of developing chronic pain, according to the SBT. The ICC for the entire sample was 0.96 (95% CI 0.92-0.98). The Slovenian translation of the SBT showed excellent specific agreement between the initial and repeat assessments: 91.4% for the low-risk group, 85.7% for the moderate-risk group, and 95.2% for the high-risk group. In addition, it showed good content validity, as no ceiling or floor effects were detected. The Slovenian translation of the questionnaire is suitable for clinical use.

Multi-Slice CT Features Predict Pathological Risk Classification in Gastric Stromal Tumors Larger Than 2 cm: A Retrospective Study.

The Armed Forces Institute of Pathology (AFIP) had higher accuracy and reliability in prognostic assessment and treatment strategies for patients with gastric stromal tumors (GSTs). The AFIP classification is frequently used in clinical applications. But the risk classification is only available for patients who are previously untreated and received complete resection. We aimed to investigate the feasibility of multi-slice MSCT features of GSTs in predicting AFIP risk classification preoperatively. The clinical data and MSCT features of 424 patients with solitary GSTs were retrospectively reviewed. According to pathological AFIP risk criteria, 424 GSTs were divided into a low-risk group (n = 282), a moderate-risk group (n = 72), and a high-risk group (n = 70). The clinical data and MSCT features of GSTs were compared among the three groups. Those variables (p < 0.05) in the univariate analysis were included in the multivariate analysis. The nomogram was created using the rms package. We found significant differences in the tumor location, morphology, necrosis, ulceration, growth pattern, feeding artery, vascular-like enhancement, fat-positive signs around GSTs, CT value in the venous phase, CT value increment in the venous phase, longest diameter, and maximum short diameter (all p < 0.05). Two nomogram models were successfully constructed to predict the risk of GSTs. Low- vs. high-risk group: the independent risk factors of high-risk GSTs included the location, ulceration, and longest diameter. The area under the receiver operating characteristic curve (AUC) of the prediction model was 0.911 (95% CI: 0.872-0.951), and the sensitivity and specificity were 80.0% and 89.0%, respectively. Moderate- vs. high-risk group: the morphology, necrosis, and feeding artery were independent risk factors of a high risk of GSTs, with an AUC value of 0.826 (95% CI: 0.759-0.893), and the sensitivity and specificity were 85.7% and 70.8%, respectively. The MSCT features of GSTs and the nomogram model have great practical value in predicting pathological AFIP risk classification between high-risk and non-high-risk groups before surgery.

PARKİNSON HASTALARINDA FARKLI DENGE DURUMLARINA GÖRE GÖVDE KONTROLÜNÜN, EL FONKSİYONUNUN ve EL REAKSİYON ZAMANININ KARŞILAŞTIRILMASI

Objective&#x0D; This study aims to compare trunk control, manual dexterity,&#x0D; and reaction time according to different balance&#x0D; states in people with Parkinson's Disease (PwPD).&#x0D; Material and Method&#x0D; A total of 25 PwPD, 6 of whom were women, were&#x0D; included in the study. Individuals were divided into the&#x0D; Moderate-risk group (n=11) and the Low-risk group&#x0D; (n=14) according to the Berg Balance Scale (BBS)&#x0D; cut-off scores. To evaluate trunk control and functions,&#x0D; static and dynamic sitting balance were evaluated&#x0D; with the Trunk Impairment Scale (TIS), which&#x0D; consists of trunk coordination sub-parameters. Hand&#x0D; grip strength was measured with the Jamar hand dynamometer,&#x0D; manual dexterity was measured bilaterally&#x0D; with the Purdue Pegboard Test, and hand reaction&#x0D; time was measured bilaterally with the the Ruler Drop&#x0D; Test.&#x0D; Results&#x0D; When the groups were compared for trunk control,&#x0D; there was a significant difference in the dynamic sitting&#x0D; subparameter and the total score of the trunk impairment&#x0D; scale in favor of the low-risk group (p=0.030,&#x0D; p=0.005). However, there was no difference between&#x0D; the groups in static sitting and coordination sub-parameters&#x0D; (p=0.181, p=0.558). There was no difference&#x0D; between the groups in the grip strength, dexterity, and&#x0D; reaction time of both hands (p&gt;0.05).&#x0D; Conclusion&#x0D; While the dynamic sitting balance and trunk impairment&#x0D; of the moderate-risk balance group was worse&#x0D; than the low-risk group, manual dexterity and reaction&#x0D; time were similar. Further studies are needed to&#x0D; examine manual dexterity for trunk and distal mobility,&#x0D; which play a key role in proximal stabilization and balance&#x0D; in PwPD.

Reducing the risk of prenatal alcohol exposure and FASD through social services: promising results from the FAR SEAS pilot project.

Within FAR SEAS, a multi-component evidence-based community intervention was implemented and evaluated in Mazovia (Poland), with the aim of preventing alcohol-exposed pregnancies, and therefore preventing FASD. Multi-disciplinary professionals from different services (social, addiction, and psychology), recruited women of child-bearing age (pregnant and not pregnant) in local communities, screened them for alcohol risk, and allocated participants (n = 441) to groups for low- (70%), moderate- (23%), or high-risk (7%) of alcohol exposed pregnancy, to provide interventions tailored to their needs. The non-parametric sign test, testing differences between pairs of observations before and after intervention was used to evaluate the outcomes. Follow-up data (collected from 93% of participants) indicated positive changes in the key outcome variables: risky alcohol consumption dropped by 81%, contraception use increased by 15% and visiting a gynecologist increased by 39%; as well as in associated psychosocial risk factors (decrease in cigarette and drug use, domestic violence and depressive symptoms). No changes were noted in frequency of other service use (medical, psychological, or social). The most prominent changes were observed in the moderate-risk group. Changing risky behaviors (alcohol consumption and sex without contraception) to prevent alcohol exposed pregnancies is feasible at the local level, even without engagement of medical professionals. Key challenges, related to engaging professionals and local authorities, must be addressed; and procedures should be adapted to local contexts and needs.

Construction of a Risk Prediction Model for Lung Cancer Based on Lifestyle Behaviors in the UK Biobank Large-Scale Population Cohort

To identify the risk factors related to lifestyle behaviors that affect the incidence of lung cancer, to build a lung cancer risk prediction model to identify, in the population, individuals who are at high risk, and to facilitate the early detection of lung cancer. The data used in the study were obtained from the UK Biobank, a database that contains information collected from 502 389 participants between March 2006 and October 2010. Based on domestic and international guidelines for lung cancer screening and high-quality research literature on lung cancer risk factors, high-risk population identification criteria were determined. Univariate Cox regression was performed to screen for risk factors of lung cancer and a multifactor lung cancer risk prediction model was constructed using Cox proportional hazards regression. Based on the comparison of Akaike information criterion and Schoenfeld residual test results, the optimal fitted model assuming proportional hazards was selected. The multiple factor Cox proportional hazards regression was performed to consider the survival time and the population was randomly divided into a training set and a validation set by a ratio of 7:3. The model was built using the training set and the performance of the model was internally validated using the validation set. The area under the receiver operating characteristic (ROC) curve ( AUC) was used to evaluate the efficacy of the model. The population was categorized into low-risk, moderate-risk, and high-risk groups based on the probability of occurrence of 0% to <25%, 25% to <75%, and 75% to 100%. The respective proportions of affected individuals in each risk group were calculated. The study eventually covered 453 558 individuals, and out of the cumulative follow-up of 5 505 402 person-years, a total of 2 330 cases of lung cancer were diagnosed. Cox proportional hazards regression was performed to identify 10 independent variables as predictors of lung cancer, including age, body mass index (BMI), education, income, physical activity, smoking status, alcohol consumption frequency, fresh fruit intake, family history of cancer, and tobacco exposure, and a model was established accordingly. Internal validation results showed that 8 independent variables (all the 10 independent variables screened out except for BMI and fresh fruit intake) were significant influencing factors of lung cancer ( P<0.05). The AUC of the training set for predicting lung cancer occurrence at one year, five years, and ten years were 0.825, 0.785, and 0.777, respectively. The AUC of the validation set for predicting lung cancer occurrence at one year, five years, and ten years were 0.857, 0.782, and 0.765, respectively. 68.38% of the individuals who might develop lung cancer in the future could be identified by screening the high-risk population. We established, in this study, a model for predicting lung cancer risks associated with lifestyle behaviors of a large population. Showing good performance in discriminatory ability, the model can be used as a tool for developing standardized screening strategies for lung cancer.

692 Standardised Management of Hallux Fractures Within Virtual Fracture Clinic: A Quality Improvement Project

Abstract Aim Hallux fractures are a common referral to Virtual Fracture Clinic (VFC), comprising 6% of all referrals made within our Major Trauma Centre (MTC). The cumulative time taken to process these cases equates to 3.75 hours per month. This commitment of time and resources endeavoured us to evaluate these hallux fracture referrals with the aim to develop a clear treatment pathway to improve the efficiency of VFC whilst safeguarding patient safety. Method A database was created containing all patients seen in VFC between 01/01/2022 and 31/01/2022 (n = 279). From this database 15 hallux fracture cases were identified. Using this data, a treatment pathway was created that stratified hallux fractures into high, moderate and low risk groups. This pathway was then implemented within our local A&amp;E department and surrounding minor injury units to allow clinicians to safely discharge uncomplicated hallux fractures back into the community with appropriate safety netting literature. A 2nd cycle was carried out to evaluate the effectiveness of the treatment pathway by reviewing the number of hallux fracture cases referred to VFC between 17/10/2022 and 14/11/2022. Results After implementing our treatment pathway, we saw a 62% reduction in the number of inappropriate referrals made to VFC. Furthermore, we saw a 100% increase in the number of appropriate complex fractures that were brought back to fracture clinic for formal review. Conclusions Our treatment pathway has demonstrated a significant difference in how hallux fractures are managed within our MTC in a manner that improves efficiency without compromising patient safety.

Model for Predicting Central Nervous System Relapse in Diffuse Large B-Cell Lymphoma and Discussion of Prophylaxis Measures

Relapse of the central nervous system (CNS) is a rare but fatal complication in diffuse large B-cell lymphoma (DLBCL). The purpose of this study is to learn how to identify high-risk patients and take effective preventive measures. We retrospectively analyzed 1,290 adult patients with DLBCL at Peking University Cancer Hospital and Shanxi Bethune Hospital between 2010 and2020. There were 55 patients with CNS relapse who had a median follow-up of 5years. The risk of CNS relapse was 1.58% in the low-risk group, 5.66% in the moderate-risk group, and 11.67% in the high-risk group based on CNS International Prognostic Index (CNS-IPI). We found that CNS-IPI and testicular involvement were risk factors for CNS relapse, with OR 1.913 (95% CI: 1.036∼3.531; P= 0.038) versus. OR 3.526 (95% CI: 1.335∼9.313; P= 0.011), respectively. Intrathecal MTX and/or cytarabine prophylaxis was used in 166 patients (13.94%), intravenous (IV) high-dose methotrexate (HD-MTX) prophylaxis in 8 patients (0.67%), and intrathecal plus intravenous prophylaxis in 15 patients (1.26%). There was no significant difference in CNS relapse risk between IT, HD-MTX, and no prophylaxis recipients (12.7% vs. 0% vs. 23.6%, respectively, P=0.170). The risk of CNS relapse was similar whether or not patients accepted prophylaxis (5-year risk 4.1% vs. 2.2%, P= 0.140). Central nervous system (CNS) relapse isassociated with high risk CNS-IPI and testicular involvement. Therefore, it is necessary to pursue novel prophylactic strategies for CNS relapse.

A prospective assessment of the validity of the CUA neurogenic bladder guideline.

The Canadian Urological Association (CUA) neurogenic bladder guideline surveillance strategy for neurogenic lower urinary tract dysfunction (NLUTD) has not been formally evaluated. Our objective was to evaluate the validity of the risk stratification suggested in these guidelines. This was a prospective, observational cohort study of adult NLUTD patients with spinal cord injury, multiple sclerosis, or spina bifida who required urodynamics. Patients with a requirement for immediate bladder surgery (not suitable for surveillance) were excluded. Patients completed standardized medical history/questionnaires, baseline urodynamics, renal imaging, and creatinine tests. The primary outcome was the need for different types of urological management between the high-risk and moderate-risk groups. We enrolled 68 patients; most commonly, these were spinal cord injury patients, and most people were using intermittent catheters. At baseline, 62% (40/68) were classified as high-risk. In this group, there was a numerically greater proportion who received a recommendation for a new urological medication (48% vs. 25%, p=0.06) or a change to their bladder management (45% vs. 36%, p=0.44). A total of 26 high-risk and 23 medium-risk NLUTD patients had a one- year followup visit. A larger proportion of the high-risk patients had a recommendation for a new bladder medication (15.4% vs. 8.7% p=0.47), intravesical onabotulinum toxin (34.6% vs. 13% p=0.08), or an alternate method of bladder management (15.4% vs. 4.3%, p=0.2). Mean creatinine change was slightly greater in the high-risk group (+6.1 vs. +0.4 umol/L, p=0.05). Approximately 1/3 of both high-risk and moderate-risk patients didn't accept the recommended interventions. A higher proportion of high-risk NLUTD patients had urology-relevant interventions recommended, both at baseline and at their one-year followup visit. This supports the general concept of risk stratification and the variables used to define high-risk in the CUA's neurogenic bladder guideline.

Nutritional Screening of Sick Neonates in NICU and Its Relation to Short Term Outcome

Background Malnutrition during infancy has long-term physical and psychological adverse effect on development. Neonatal nutritional assessment is important to determine the daily energy and nutritional requirements needed for optimum growth and development. Objectives Assessment of the validity of Nutrition risk screening tools, and to stratify neonates admitted to the NICU according to their nutritional risk and correlate this to their outcome. Methods A cross-sectional study was conducted in NICU at Ain Shams University Hospitals. All neonates admitted to the NICU in a set period of 6 months from December 2017 to June 2018 were enrolled in the study after written and verbal consents were taken from parents.All neonates were subjected to the following: Anthropometric measurements (weight, length, head circumference, mid arm circumference, skin fold thickness and ponderal index at admission), Dietary assessment and laboratory investigations. The number of patients at this study were classified according to ‘Ohio neonatal nutrition screening tool (NNST) into a three risk groups: •low risk group: no = 121 •moderate risk: no = 15 •High risk: no = 14 Results The study showed that full intake enteral nutrition was reached in 100% of low and moderate risk groups and in only 64.3% of high risk group. Continuous parenteral nutrition was required in 100% of moderate and high risk groups and in only 7.4% of the low risk group. It also showed that the length of hospital stay was increased in the moderate risk group to 22 days (16-26) and in the high risk group to 8.5 days (3-16) while in the low risk group was only 5 days (4-7).Considering the hospital discharged patients: 100% of the moderate risk group, 99.2% of the low risk group and only 21.4% of the high risk group were discharged. According to the septic score, sepsis was recorded in 85.7% in the high risk group, 66.7% in the moderate risk group and only in 24% of the low risk group. Conclusion Nutritional screening tools were able to identify neonates at nutritional risk, as it showed that High risk group patients had higher rate of mortality and higher risk of Sepsis and thus they were in need for further assessment and support by nutrition specialist.

Dental Therapy of Patients Prior to Endoprostheses: A Retrospective, Telephone-Based Cohort Study.

The aim of this study was to assess, whether patients prior to endoprosthesis (EP) visit their dentist for need-oriented therapy and whether this would be associated with the occurrence of complications. Based on a cohort of patients, which was orally investigated prior to EP surgery between 04/2020 and 12/2021, a telephone interview was performed at least six months after EP implantation. Patients were classified into either low-risk (LR), moderate-risk (MR), or high-risk (HR) groups. Participants were interviewed based on a structured questionnaire regarding dental visits, dental therapy, and potential complications during the observational period. Out of the 311 patients from the baseline cohort, 96 patients after EP implantation could be included (participation rate of 31%). Nineteen patients were in LR (20%), 41 in MR (43%), and 36 in the HR group (37%). Overall, 79% (n = 76) of the patients followed the recommendation to visit their dentist; 94% of patients within the HR group visited the dentist (p = 0.02). Dental treatment procedures included tooth cleaning (57%), periodontal treatment (31%), restorative therapy/filling (28%), and tooth extraction (28%). In 64% of the HR patients (n = 23), the potential oral foci with a risk of EP infection were eliminated by their general dentist. Fourteen different complications occurred within the observation period, without any group effect (p > 0.05). In conclusion, most patients prior to EP visit their general dentist following referral, especially if they have a potential oral focus. The effect of dental clearance on infectious complications of EP remains unclear, whereby further clinical studies are needed.

Analysis of relationship between P wave dispersion and diagnosis of pulmonary arterial hypertension and risk stratification

BackgroundThe aim of this study was to measure the P-wave dispersion(PWD) in the ECG of patients with pulmonary arterial hypertension(PAH). MethodsA total of 103 PAH patients were collected, including 55 patients related with congenital heart disease(CHD) and 44 patients with idiopathic pulmonary arterial hypertension(IPAH). In addition, 30 CHD patients without PAH (nPAH-CHD group) and 30 healthy controls (HCG group) were collected as control. Patients in the PAH group were categorized into the low-risk group (30 cases), moderate-risk group (53 cases) and high-risk group (20 cases), followed by comparison of PWD difference between groups. The ROC curve was used to evaluate the diagnostic efficacy of PWD on PAH-CHD and IPAH. ResultsThe levels of PWD and maximum P wave duration(Pmax) in PAH-CHD and IPAH group were significantly higher than those in nPAH-CHD and HCG group (P < 0.05). PWD level was positively correlated with right ventricular end-diastolic diameter(RVD), right atrial end-systolic diameter(RAS), mean pulmonary arterial pressure(mPAP), pulmonary vascular resistance(PVR)(r = 0.407, 0.470, 0.477, 0.423, P < 0.001), and was negatively correlated with systolic displacement of tricuspid valve annulus(TAPSE) level (r = −0.551, P < 0.001). After risk quantification in 103 PAH patients, we found that PWD was significantly different among the low-risk, moderate-risk and high-risk groups (43.89 ± 9.91 vs. 51.29 ± 6.61, 62.15 ± 10.44, P < 0.001). CHD-PAH and IPAH were identified by PWD with a cut off value of 41.5 ms (P < 0.001), and a cut off value of 41.45 ms (P < 0.001), respectively. ConclusionsPWD might be an effective ECG indicator for PAH, which might be used as a relatively economical indicator for PAH patients to assist in early diagnosis, disease severity assessment and prognosis evaluation.
