Objectives: This study aimed to assess outcomes in patients who underwent hepatic resection for colorectal liver metastases (CRLM) with subcentimetre indeterminate pulmonary nodules (IPN) and to devise a management pathway for these patients.
Methods: Patients undergoing CRLM resection from January 2006 to December 2010 were included. Survival differences following liver resection in patients with and without IPN were determined.
Results: A total of 184 patients were included, 30 of whom had IPN. There were no significant differences between the IPN and non-IPN groups in terms of demographics, surgery and pathological factors. There were no significant differences between patients with and without IPN with respect to disease-free (P= 0.190) and overall (P= 0.710) survival. Fifteen patients with IPN progressed to metastatic lung disease over a median period of 10 months (range: 3-18 months); six of these patients underwent lung resection. Of the remaining 15 patients with IPN, eight showed no IPN progression and subsequent CT scans did not identify IPN in the remaining seven.
Conclusions: Colorectal liver metastases patients with IPN who have resectable disease should be treated with liver resection and should be subject to intensive surveillance post-resection. Although 50% of these patients will progress to develop lung metastases, this does not appear to influence survival following liver resection.

Aim: The current study aims to delineate subcutaneous adipose tissue (SAT), visceral adipose tissue (VAT), the sacrospinalis muscle, and all abdominal musculature at the L3-L5 vertebral level from non-contrast computed tomography (CT) imagery using deep learning algorithms. Subsequently, radiomic features are collected from these segmented images and subjected to medical interpretation.
Materials And Methods: This retrospective analysis includes a cohort of 315 patients diagnosed with acute necrotizing pancreatitis (ANP) who had undergone comprehensive whole-abdomen CT scans.

Patients with Parkinson's disease (PD) in the moderate and severe stages can present several walk alterations. They can show slow movements and difficulty initiating, varying, or interrupting their gait; freezing; short steps; speed changes; shuffling; little arm swing; and festinating gait. The Movement Disorder Society-Unified Parkinson's Disease Rating Scale (MDS-UPDRS) has a good reputation for uniformly evaluating motor and non-motor aspects of PD.

Background: Open surgical debridement was the main treatment option for infected pancreatic necrosis (IPN). However, it was associated with significant trauma, leading to a higher mortality rate. With the development of minimally invasive surgery, the step-up treatment principle centered around minimally invasive intervention, significantly reducing the incidence of complications and mortality rates among IPN patients.

Background: Determining the benign or malignant status of indeterminate pulmonary nodules (IPN) with intermediate malignancy risk is a significant clinical challenge. Oral microbiota-lung cancer interactions have qualified oral microbiota as a promising non-invasive predictive biomarker in IPN.
Materials And Methods: Prospectively collected saliva, throat swabs, and tongue coating samples from 1040 IPN patients and 70 healthy controls across three hospitals.
Multiple sclerosis (MS) is an autoimmune demyelinating disease that affects the central nervous system (CNS) with its chronic inflammatory component. In the treatment of MS, corticosteroids are usually implemented to reduce the disease's inflammation rate. In this case study, we present a patient with MS that initially received corticosteroids, which heightened his vulnerability to infections, particularly respiratory ones.
