Background: Patients have been identified with hemorrhagic fever (HF) caused by Huaiyangshan virus (HYSV) infection since 2009. This study aimed to investigate the characteristics of clinical symptoms, laboratory examinations, epidemiological factors, and therapeutic responses in patients with Huaiyangshan hemorrhagic fever (HYSHF).

Methods: A total of 57 patients with a suspected HF were admitted to the Department of Infectious Diseases, the Affiliated Union Hospital of Tongji Medical College between June 2009 and October 2010. A potential infection with HYSV was determined by indirect immunofluorescent assay and reverse-transcription (RT)-PCR. The clinical symptoms, epidemiological characteristics, laboratory examinations, and therapeutic responses of these patients were evaluated.

Results: Forty-eight out of 57 patients were diagnosed with HYSHF. They displayed diverse clinical symptoms, such as an acute febrile flu-like illness, and progressed to proteinuria, hemorrhagic manifestations, and encephalopathy. Some patients exhibited progressive leukopenia, thrombocytopenia, liver and kidney dysfunction, and systemic cell injury. Following symptom-specific treatment, 35 patients recovered completely and 13 patients died from severe complications, including central nervous system manifestations.

Conclusions: Patients with HYSHF displayed diverse clinical symptoms and laboratory findings. Such patients should be treated immediately and closely monitored to prevent severe complications.

18F-Sodium Fluoride PET/CT as a Tool to Assess Enthesopathies in X-Linked Hypophosphatemia.

X-linked hypophosphatemia (XLH) is a rare metabolic disorder characterized by elevated FGF23 and chronic hypophosphatemia, leading to impaired skeletal mineralization and enthesopathies that are associated with pain, stiffness, and diminished quality of life. The natural history of enthesopathies in XLH remains poorly defined, partly due to absence of a sensitive quantitative tool for assessment and monitoring. This study investigates the utility of 18F-NaF PET/CT scans in characterizing enthesopathies in XLH subjects.

Objective: To review and compare robot-assisted ipsilateral ureteroureterostomy (RALUU) and laparoscopic ipsilateral uretero-ureterostomy (LUU) in terms of efficacy and outcomes.

Methods: Clinical data of 65 children with complete renal ureteral duplication deformity admitted to the First Affiliated Hospital of Zhengzhou University from January 2015 to December 2022 were collected. Among these, 42 patients underwent laparoscopic ureteroureterostomy (LUU), designated as the LUU group, while 23 patients received robot-assisted laparoscopic ureteroureterostomy (RALUU), designated as the RALUU group.

In 2017, Kidney Disease: Improving Global Outcomes (KDIGO) published a Clinical Practice Guideline Update for the Diagnosis, Evaluation, Prevention, and Treatment of Chronic Kidney Disease-Mineral and Bone Disorder (CKD-MBD). Since then, new lines of evidence have been published related to evaluating disordered mineral metabolism and bone quality and turnover, identifying and inhibiting vascular calcification, targeting vitamin D levels, and regulating parathyroid hormone. For an in-depth consideration of the new insights, in October 2023, KDIGO held a Controversies Conference on CKD-MBD: Progress and Knowledge Gaps Toward Personalizing Care.

During qualification for mechanical circulatory support, the comprehensive assessment of a patient's mental state is an integral element of the overall medical evaluation. It encompasses a range of psychosocial issues, and as such provides information helpful in the selection of a suitable candidate for the required treatment, and sometimes identifies contraindications to it. It allows ensuring that the patient meets expectations regarding both mental health stability and adherence to medical recommendations.
