MRI as a viable alternative to CT for 3D surgical planning of cavitary bone tumors.

Cavitary bone defects, defined as a volumetric loss of native bone tissue, require accurate preoperative imaging for treatment planning. While CT (computed tomography) has traditionally been the gold standard for segmentation due to its superior resolution of cortical bone, MRI (magnetic resonance imaging) offers unique advantages, particularly in visualizing the soft tissue-bone interface. Furthermore, MRI eliminates the ionizing radiation associated with CT, making it an advantageous alternative, especially in the management of benign and low-grade malignant bone tumors.

Predicting work ability impairment in post COVID-19 patients: a machine learning model based on clinical parameters.

The Post COVID-19 condition (PCC) is a complex disease affecting health and everyday functioning. This is well reflected by a patient's inability to work (ITW). In this study, we aimed to investigate factors associated with ITW (1) and to design a machine learning-based model for predicting ITW (2) twelve months after baseline.

Surgical site infections after sarcoma resections in the peripelvic region: do we need perioperative antibiotic prophylaxis?

Introduction: Surgical site infections (SSI) are one of the most common complications after extensive sarcoma resections and represent a daily challenge. SSI occur in up to 50% of cases particularly in the peripelvic area. One possible approach to reduce infection rate is perioperative antibiotic prophylaxis.

Spirometric reference equations and lung function testing in adults from Southwestern Tanzania.

Background: The increasing relevance of lung function testing in diagnosing and treating pulmonary diseases globally requires adequate spirometric reference equations. However, locally derived reference standards from African countries are widely missing.

Methods: This cross-sectional study was conducted in Southwestern Tanzania.

Substantial differences in perception of disease severity between post COVID-19 patients, internists, and psychiatrists or psychologists: the Health Perception Gap and its clinical implications.

Patient-reported outcome measures (PROMs) such as the Numeric Pain Rating Scale (NPRS) or Likert scales addressing various domains of health are important tools to assess disease severity in Post COVID-19 (PC) patients. By design, they are subjective in nature and prone to bias. Our findings reveal substantial differences in the perception of disease severity between patients (PAT), their attending internists (INT) and psychiatrists/psychologists (PSY).

Valve-Sparing Aortic Root Replacement With Reimplantation vs Remodeling: A Meta-analysis.

Background: Long-term outcomes of valve-sparing aortic root replacement (VSARR) with reimplantation vs remodeling in patients undergoing aortic root surgery remains a controversial subject.

Methods: This study was a pooled meta-analysis of Kaplan-Meier-derived data from comparative studies published by December 31, 2022.

Results: Fifteen studies met our eligibility criteria, comprising 3044 patients (1991 in the reimplantation group and 2018 in the remodeling group).
