AI Article Synopsis

  • Preoperative respiratory muscle endurance training (RMET) was studied to assess its impact on patients undergoing surgery for non-small cell lung cancer (NSCLC).
  • The study showed that the training group, who underwent RMET, had a significant increase in respiratory muscle endurance compared to the control group, which did not receive the training.
  • Additionally, the training group experienced fewer pulmonary complications post-surgery, highlighting the potential benefits of RMET for improving recovery in NSCLC patients.

Article Abstract

Background: Resection surgery is the main treatment for non-small cell lung cancer (NSCLC). Postoperative complications and mortality are mostly linked to respiratory failure consecutive to respiratory muscle overload.

Aim: We aimed to evaluate the effect of preoperative respiratory muscle endurance training (RMET) on respiratory muscle capacity and postoperative complications in patients undergoing NSCLC resection.

Design: Randomized controlled trial.

Setting: French university hospital.

Population: Patients eligible for NSCLC resection.

Methods: The training group (T group) performed a 3-week preoperative RMET added to usual chest physical therapy while the control group (C group) had only the latter. The primary outcome was the change in respiratory muscle endurance. Secondary outcomes were postoperative complications and mortality. Assessments were performed similarly at baseline and after the intervention. We conducted multivariable analyses with analysis of covariance (ANCOVA) taking into account baseline values for isocapnic hyperpnoea endurance test, exercise capacity and pulmonary function tests. The number of pulmonary postoperative complication was analyzed by Fisher-exact test.

Results: We included 26 patients with NSCLC (14 in the T group and 12 in the C group). Respiratory muscle endurance significantly increased in the T group after the RMET compared with C group (+229±199 vs. -5±371 sec, P=0.001). This increase was associated with a significantly lower number of pulmonary postoperative complications (2 vs. 10, P=0.037).

Conclusions: Preoperative RMET improved respiratory muscle endurance and decreased pulmonary postoperative complications after surgery for NSCLC. These positive results obtained after RMET may help improve the perioperative course for such patients. These results should be confirmed in larger randomized controlled trials, including higher number of patients especially with altered respiratory muscle function.

Clinical Rehabilitation Impact: Low-cost and easy to perform, RMET training could serve as complementary tool to usual chest physical therapy, before lung resection surgery.

Challenges in Rehabilitation of a Tetanus Patient With Severe Complications.

Tetanus is a rare but life-threatening neurological disorder caused by neurotoxins produced by . Although mortality rates have significantly decreased with modern intensive care, severe cases remain challenging due to prolonged Intensive Care Unit (ICU) stays, complications, and rehabilitation barriers. We report the case of an 81-year-old male with a history of hypertension and femoral neck fracture who developed severe tetanus following a contaminated forehead laceration.

Background: Vocal therapy, such as singing training, is an increasingly popular pulmonary rehabilitation program that has improved respiratory muscle status in patients with chronic obstructive pulmonary disease (COPD). However, variations in singing treatment protocols have led to inconsistent clinical outcomes.

Objective: This study aims to explore the content of vocalization training for patients with COPD by observing differences in respiratory muscle activation across different vocalization tasks.

Characterization of SARS-CoV-2 Entry Genes in Skeletal Muscle and Impacts of In Vitro Versus In Vivo Infection.

J Cachexia Sarcopenia Muscle

Meakins-Christie Laboratories and Translational Research in Respiratory Diseases Program, Research Institute of the McGill University Health Centre, Montreal, Quebec, Canada.

Background: COVID-19 has been associated with both respiratory (diaphragm) and non-respiratory (limb) muscle atrophy. It is unclear if SARS-CoV-2 infection of skeletal muscle plays a role in these changes. This study sought to: 1) determine if cells comprising skeletal muscle tissue, particularly myofibres, express the molecular components required for SARS-CoV-2 infection; 2) assess the capacity for direct SARS-CoV-2 infection and its impact on atrophy pathway genes in myogenic cells; and 3) in an animal model of COVID-19, examine the relationship between viral infection of skeletal muscle and myofibre atrophy within the diaphragm and limb muscles.

Kdm2a inhibition in skeletal muscle improves metabolic flexibility in obesity.

Skeletal muscle is a critical organ in maintaining homoeostasis against metabolic stress, and histone post-translational modifications are pivotal in those processes. However, the intricate nature of histone methylation in skeletal muscle and its impact on metabolic homoeostasis have yet to be elucidated. Here, we report that mitochondria-rich slow-twitch myofibers are characterized by significantly higher levels of H3K36me2 along with repressed expression of Kdm2a, an enzyme that specifically catalyses H3K36me2 demethylation.

Approximately half of critically ill adults experience intensive care unit acquired weakness (ICUAW). Patients who develop ICUAW may have negative outcomes, including longer duration of mechanical ventilation, greater length of stay, and worse mobility, physical functioning, quality of life, and mortality. Early physical rehabilitation interventions have potential for improving ICUAW; however, randomized trials show inconsistent findings on the efficacy of these interventions.
