Prevalence of dysphagia in patients after orthopedic surgery.

OBJECTIVES: Oropharyngeal dysphagia is one of the most prevalent health complications in older adults. The prevalence of postoperative dysphagia is expected to rise with the increasing number of older patients undergoing orthopedic surgery; however, the specific prevalence and contributing factors remain unclear. This scoping review aimed to identify the prevalence and factors related to postoperative dysphagia in older orthopedic patients. METHODS: This review included studies published up to September 2022 on postoperative patients aged ≥ 60 years who underwent orthopedic surgery. We searched MEDLINE, EMBASE, CINAHL, CENTRAL, Web of Science, and Ichushi-Web. RESULTS: In total, 21 of the 2158 identified studies were reviewed. The studies were classified into the three categories according to the surgical site: cervical spine disease (n = 12), hip fracture (n = 7), and others (n = 2). The estimated dysphagia prevalence rates [95 % confidence interval] of cervical spine disease, hip fractures, and others were 16 % [8-27], 32 % [15-54], and 6 % [4-8], respectively. Factors related to postoperative dysphagia included cervical alignment in cervical spine disease, being older within the cohort, preoperative health status, malnutrition, and sarcopenia in hip fractures. CONCLUSIONS: The prevalence of postoperative dysphagia after orthopedic surgery was highest for hip fractures, followed by cervical spine and others. These results suggest non-neurogenic dysphagia in older patients undergoing orthopedic surgery and indicate that sarcopenia may contribute to postoperative dysphagia in this population. Therefore, further research should clarify the trajectory of postoperative dysphagia and the effectiveness of rehabilitation for postoperative dysphagia after orthopedic surgery.

Diagnosis and prevalence of sarcopenic obesity in patients with colorectal cancer: A scoping review.

BACKGROUND & AIMS: Sarcopenic obesity (SO) is associated with worse outcomes in patients with colorectal cancer (CRC); however, the diagnostic methods and prevalence of SO vary among studies. Therefore, we conducted this scoping review to investigate the diagnosis of SO in CRC, identify the associated problems, and determine its prevalence. METHODS: A systematic review was conducted according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses Extension for Scoping Reviews reporting guidelines. A literature search was performed by two independent reviewers on studies that diagnosed SO in CRC using the MEDLINE, EMBASE, CINAHL, CENTRAL, Web of Science, and Ichushi-Web (in Japanese) databases. Observational, longitudinal, cross-sectional, and clinical trials written in English or Japanese as of July 2022 were included. Studies that did not define SO were excluded from the analysis. The study protocol was pre-registered in Figshare. RESULTS: In total, 670 studies were identified, 22 of which were included. Eighteen studies used sarcopenia in combination with obesity to diagnose SO. Sarcopenia was mainly diagnosed using skeletal muscle mass index (SMI), and only one combined with grip strength or gait speed. Obesity was diagnosed based on the body mass index (BMI; n = 11), followed by visceral fat area (VFA; n = 5). The overall prevalence of SO in patients with CRC was 15% (95%CI, 11-21%). The prevalence of SO in surgical resection and colorectal cancer liver metastases was 18% (95%CI, 12-25%) and 11% (95%CI, 3-36%), respectively. CONCLUSIONS: SO in patients with CRC was mainly diagnosed based on a combination of SMI and BMI, and muscle strength and body composition were rarely evaluated. The prevalence of SO was approximately 15%, depending on the diagnostic methods used. Since SO in patients with CRC is associated with poor prognosis, further research on diagnostic methods for the early detection of SO and its clinical outcomes is needed.

Association of Sarcopenic Dysphagia with Underlying Sarcopenia Following Hip Fracture Surgery in Older Women.

This study aimed to investigate the association between the development of dysphagia in patients with underlying sarcopenia and the prevalence of sarcopenic dysphagia in older patients following surgical treatment for hip fracture. Older female patients with hip fractures (n = 89) were studied. The data of skeletal muscle mass, hand-grip strength, and nutritional status were examined. The development of dysphagia postoperatively was graded using the Food Oral Intake Scale by a certified nurse in dysphagia nursing. The patients' mean age was 85.9 ± 6.5 years. The prevalence of sarcopenia was 76.4% at baseline. Of the 89 patients, 11 (12.3%) and 12 (13.5%) had dysphagia by day 7 of hospitalization and at discharge, respectively. All patients who developed dysphagia had underlying sarcopenia. Lower skeletal muscle mass index (SMI) (<4.7 kg/m2) and grip strength (<8 kg) at baseline indicated a higher incidence of dysphagia on day 7 (p = 0.003 and Phi = 0.391) and at discharge (p = 0.001 and Phi = 0.448). Dysphagia developed after hip fracture surgery could be sarcopenic dysphagia, and worsening sarcopenia was a risk factor for dysphagia following hip fracture surgery. Clinicians and medical coworkers should become more aware of the risks of sarcopenic dysphagia. Early detection and preventive interventions for dysphagia should be emphasized.
