Urinary bladder cancer (UBC) is dominantly the cancer of the elderly occurring primarily in the 6h, 7!h and 81h decade of life. The aim of this study was to evaluate diagnostic accuracy of ultrasound T-staging (UTS) of UBC in dhe group of elderly patients. In 152 elderly patients referred to transabdominal ultrasound examination in two different facilities (76 each) due to various symptoms (primarily painless gross or microscopic haematuria) UBC was diagnosed. Initial UTS at the moment of detection was performed and compared with final histological T-staging (HTS). A high level of conformity between UTS and HTS was detected. In a total of 152 patients with UBC there were 115 (75.66%) patients with complete match between the UTS and HTS, 24 (15.79%) patients with minimal variation within one stage, and 13 (8.55%) patients with one stage difference between the UTS and HTS. The best result was established for the stage T1, where the accuracy was 94.5%. In other stages the accuracy was between 84.9% and 91.8%. The Youden's index for all the stages was over 0.6. UTS has a high diagnostic accuracy, especially for stages T1 and T2. It is extremely useful tool in differentiating the superficial UBC from the muscle-invasive one, being of significant importance in planning the further treatment of elderly patients and having important role in choosing appropriate surgical approach.

Effectiveness of the User-Centered "Healthcare CEO" App for Patients With Type 1 Diabetes Transitioning From Adolescence to Early Adulthood: Protocol for a Randomized Controlled Trial.

Background: Young patients aged 16 to 25 years with type 1 diabetes (T1D) often encounter challenges related to deteriorating disease control and accelerated complications. Mobile apps have shown promise in enhancing self-care among youth with diabetes. However, inconsistent findings suggest that further evidence is necessary to confirm the effectiveness of app-based interventions.

Article Synopsis
- Hyperacute cardiac CT is more effective than transthoracic echocardiography in detecting intracardiac thrombus, but its routine use is limited due to costs and risks.
- A study of 1,136 ischemic stroke or TIA patients found that longer arterial input function (AIF) dispersal times correlate with the presence of thrombus and worse outcomes, with a specific cutoff of 33 seconds indicating higher risk.
- The findings support using AIF dispersal measurements to help identify patients who may benefit from cardiac imaging, potentially optimizing resource use in stroke management.
Pathophysiological Significance of α-Synuclein in Sympathetic Nerves: In Vivo Observations.

From the Autonomic Medicine Section, Clinical Neurosciences Program, Division of Intramural Research, National Institute of Neurological Disorders and Stroke, NIH, Bethesda, MD.
Background And Objectives: Lewy body diseases (LBDs) such as Parkinson disease (PD) feature increased deposition of α-synuclein (α-syn) in cutaneous sympathetic noradrenergic nerves. The pathophysiologic significance of sympathetic intraneuronal α-syn is unclear. We reviewed data about immunoreactive α-syn, tyrosine hydroxylase (TH, a marker of catecholaminergic fibers), and the sympathetic neurotransmitter norepinephrine (NE) in skin biopsies from control participants and patients with PD, the related LBD pure autonomic failure (PAF), the non-LBD synucleinopathy multiple system atrophy (MSA), or neurologic postacute sequelae of severe acute respiratory syndrome coronavirus 2 (neuro-PASC).

Monopolar electrocautery is usually a safe and effective technique used in laparoscopic cholecystectomy and bile duct surgery, but it may lead to adverse consequences, even ventricular fibrillation (VF). Amiodarone is an effective antiarrhythmic drug commonly used in practice to treat ventricular and atrial arrhythmias, but it may induce tachyarrhythmia or even VF. We report a case of VF occurring twice during cholecystectomy.

Background: Platelet recovery was an important prognostic indicator in severe fever with thrombocytopenia syndrome (SFTS). This study focused on risk factors affecting platelet recovery in surviving SFTS patients, which can assist clinicians in the early screening of patients associated with a greater risk of mortality.
Method: We retrospectively analyzed the clinical data of SFTS patients admitted to Yantai Qishan Hospital throughout 2023.
