AI Article Synopsis
- The study investigates how preoperative respiratory function impacts patients' outcomes after lung surgery for stage I lung cancer.
- Out of 192 patients analyzed, those with restrictive ventilatory impairment had significantly lower rates of recurrence-free survival and overall survival compared to those without such impairment.
- The findings suggest that for patients with restrictive issues, more caution is needed when selecting surgical procedures like lobectomy or segmentectomy.
Article Abstract
Background: Respiratory impairment can lead to pulmonary complications after surgery; therefore, it should be considered when determining the choice of surgical procedure. Several studies have examined the relationship between preoperative respiratory function and postoperative mortality and morbidity after lung resection; however, there are no indicators for limited surgical procedure selection. The aim of this study was to examine the association between preoperative respiratory function and postoperative early and late complications, recurrence-free survival (RFS), and overall survival (OS) in patients undergoing pulmonary resection for stage I lung cancer.
Methods: We performed a retrospective analysis of data from 192 patients undergoing pulmonary resection for primary pathological stage IA non-small cell lung cancer (NSCLC) at the Iwakuni Clinical Center in Japan between 2012 and 2015. We reviewed clinicopathological characteristics including preoperative pulmonary function and elucidated the relationship between them and postoperative survival.
Results: Obstructive ventilatory impairment was present in 55 patients (28.6%), and restrictive ventilatory impairment was present in 31 patients (16.1%). Seven patients (3.6%) had both ventilatory impairment. Obstructive ventilatory impairment did not affect the 5-year RFS (P=0.08) or OS (P=0.21). However, restrictive ventilatory impairment reduced the 5-year RFS (P=0.002) and OS (P=0.009). The rates of early and late complications were not significantly different based on the preoperative respiratory function.
Conclusions: In patients with preoperative restrictive ventilatory impairment in whom lobectomy or segmentectomy cannot be performed, careful consideration is needed for surgical indications.

Traumatic cervical spinal cord injury in southeastern Norway: acute treatment, specialized rehabilitation referral and mortality.
Front Neurol
December 2024
Department of Neurosurgery, Oslo University Hospital, Oslo, Norway.
Background: Traumatic cervical spinal cord injury (cSCI) is a serious condition that requires a multidisciplinary treatment approach involving care at a neurotrauma center (NTC) and specialized rehabilitation. Contemporary population-based studies of cSCI are important for ensuring the quality and planning of health care approaches for these patients.
Methods: This is a population-based cohort study of patients with traumatic cSCI who were admitted to the NTC in Southeast Norway between 2015 and 2022.

Background: The Post-COVID-19 Functional Status (PCFS) scale is a validated tool used to measure the functional status of patients discharged from the hospital.
Objectives: To describe the functional limitations of hospitalized COVID-19 patients at the time of discharge and two months afterward, and to identify risk factors associated with functional impairment.
Design: Retrospective study.

Article Synopsis
- This study aimed to explore the link between glycemic control and lung health using data from 5,610 participants in the NHANES survey from 2007-2012, focusing on respiratory symptoms and lung function tests.
- Results indicated that a 1% increase in blood glucose was negatively correlated with lung function, leading to reduced forced expiratory volume (FEV1) and forced vital capacity (FVC), along with a higher risk of breathing difficulties and mortality for those with restrictive lung disease.
- Improved glycemic control was associated with early markers of lung damage, whereas poor control correlated with more severe lung dysfunction, emphasizing the importance of managing blood glucose levels for respiratory health.
Association of Physiological Reserve Obtained from Cardiopulmonary Exercise Testing and Frailty with All-Cause Mortality in Hemodialysis Patients.

Background: Potential impairment of exercise capacity is prevalent even in patients undergoing hemodialysis without frailty. Cardiopulmonary exercise testing (CPET) can detect physiological reserves such as cardiopulmonary, muscle, and autonomic function. We hypothesized that these indices could accurately determine the prognosis of patients on hemodialysis and analyzed them based on their relationship to frailty.
