Prognostic importance of central thrombus in hemodynamically stable patients with pulmonary embolism

Background: The association between mortality and localization of central thrombus in hemodynamically stable patients with pulmonary embolism (PE) is unclear. Sufficient data are not available to help clinicians to select between low molecular weight heparin (LMWH), unfractionated heparin (UFH) and thrombolytics for the management of central thrombus. The present study aims to investigate whether central thrombus in the pulmonary artery affects 30-day mortality rate, and to compare the outcomes of different treatment approaches in patients with central thrombus. Methods: This multi-central, prospective, observational study included 874 hemodynamically stable patients with PE confirmed by multidetector computed tomography scan. The localization of the emboli was evaluated and categorized as central (saddle or at least one main pulmonary artery), lobar or distal. The primary study outcome was 30-day all-cause mortality. Results: Localization of the emboli was central in 319 (36.5%) patients, lobar in 264 (30.2%) and distal in 291 (33.2%) patients. Seventy-four (8.5%) patients died during the 30-day follow-up period. All-cause mortality rate was 11.9%, 6.8% and 6.2% in patients with central, lobar, and distal emboli, respectively (p < 0.001). Multivariate analysis did not show that hemodynamically stable central thrombus was an independent predictor of mortality. Additionally, mortality rate was not significantly different between UFH, LMWH and thrombolytic therapy groups. Conclusions: The present study showed that central thrombus was not an independent predictor of mortality in hemodynamically stable PE patients. LMWH and UFH were similarly effective in the treatment of this patient group.

Advancing Crayfish Disease Detection : A Comparative Study of Deep Learning and Canonical Machine Learning Techniques

This study evaluates the effectiveness of deep learning and canonical machine learning models for detecting diseases in crayfish from an imbalanced dataset. In this study, measurements such as weight, size, and gender of healthy and diseased crayfish individuals were taken, and at least five photographs of each individual were used. Deep learning models outperformed canonical models, but combining both approaches proved the most effective. Utilizing the ResNet50 model for automatic feature extraction and subsequent training of the RF algorithm with these extracted features led to a hybrid model, RF-ResNet50, which achieved the highest performance in diseased sample detection. This result underscores the value of integrating canonical machine learning algorithms with deep learning models. Additionally, the ConvNeXt-T model, optimized with AdamW, performed better than those using SGD, although its disease detection sensitivity was 1.3% lower than the hybrid model. McNemar’s test confirmed the statistical significance of the performance differences between the hybrid and the ConvNeXt-T model with AdamW. The ResNet50 model’s performance was improved by 3.2% when combined with the RF algorithm, demonstrating the potential of hybrid approaches in enhancing disease detection accuracy. Overall, this study highlights the advantages of leveraging both deep learning and canonical machine learning techniques for early and accurate detection of diseases in crayfish populations, which is crucial for maintaining ecosystem balance and preventing population declines.Peer reviewe

Efficacy of Antibiotic Coated Clean Intermittent Catheterization in Children with Neurogenic Bladder

Aim: The primary goal of urologic management in children with neurogenic bladder is to reduce the risk of urinary tract infection (UTI) and associated renal injury. We aimed to evaluate the use of antibacterial-coated clean intermittent catheterization (CIC) catheters for neurogenic bladder patients in comparison with standard catheters.  Material and Methods: We performed a retrospective study of 144 neurogenic bladder patients aged 6-16 years old, who received CIC at two major centers between January 2007 and June 2016. Group 1 consisted of children used antibacterial coated (chitosan) catheter (n=55), group 2 of children used standard CIC without antibacterial (n=42) and group 3 of children used standard CIC returned into antibiotic coated CIC (n=29). Febrile urinary tract infection and asymptomatic bacteriuria were evaluated among patients with antibacterial coated or standard catheters. We also focused on a subgroup of patients with high risk of urinary tract infection (grade 3> vesicoureteral reflux, previously scar formation in renal scintigraphy).  Results: Totally 126 patients (89 female, 37 male) were involved in this study. The mean age of the study group was 9.6±2.6 years (range 6 to 16) and the mean follow-up 58±14 months (min: 22, max: 69). There was no significant difference between three groups for asymptomatic bacteriuria and febrile UTI frequencies. However, febrile UTI frequencies and de nova scar formation in renal scintigraphy were higher in previously defined subgroup of patients with high risk of urinary tract infection in group 2 than group1 and 3.  Discussion: Both antibiotic coated and standard CIC can be used in children with neurogenic bladder with similar complication rates. Patients with high risk of urinary tract infection (higher than grade 3 vesicoureteral reflux, dilated ureter, previously de nova scar formation in renal scintigraphy) will benefit from antibacterialcoated catheters rather than standard ones

A longitudinal study on lung disease in dental technicians: What has changed after seven years?

Objectives: The aim of this 7-year follow-up study was to determine respiratory changes in dental technicians. Material and Methods: In our region, in the year 2005, 36 dental technicians were evaluated with a cross-sectional study on respiratory occupational diseases, and in 2012 we evaluated them again. Inclusion of information on respiratory symptoms and demographic features questionnaires was applied. Pulmonary function tests (PFT) were performed. Chest X-rays (CXR) were evaluated according to the ILO-2000 classification. For the comparisons of the technicians' findings in 2005 and 2012, data analyses were performed with the Wilcoxon test in addition to descriptive statistical procedures. Results: In 2012, 19 out of the 36 technicians continued to work in the same place, so we were able to evaluate their findings. The prevalence of respiratory symptoms in dental technician was as follows: dyspnea 7 (37%), cough 6 (32%), and phlegm 5 (26%). According to ILO classifications in 2005, among the 36 technicians, 5 (13.8%) had pneumoconiosis. At the end of 7 years, there were 9 pneumoconiosis cases among the 19 remaining technicians (47%). Thus, there was a statistically significant progression on the profusion of the radiologic findings (p < 0.005). Also there was a significant worsening on spirometric findings (p < 0.05). Conclusion: In dental technicians, a determination of both radiologic and functional progressions at the end of 7 years demonstrate that the primary and secondary preventive measures are necessary for these workplaces. Workplaces must be regularly controlled for worker health and hygiene
