Can bone mass measured via bioelectrical impedance analysis be used to diagnose sarcopenia?

The simplification of diagnostic criteria is critical to promoting interventions for sarcopenia. This study aimed to evaluate the relationship between sarcopenia and bone mass [measured by bioelectrical impedance analysis (BIA)], as well as to identify new indicators associated with this disease. Basic interviews and measurement of physical function were performed on 474 community-dwelling older adults (aged 77.1 ±â€…7.6 years), including older adult patients with sarcopenia, in Wakasa Town, Fukui Prefecture. The findings led to 363, 71, and 40 participants being classified as 'normal', 'pre-sarcopenia', and 'having sarcopenia', respectively. An Ordinal Logistic Regression Analysis showed that age, bone mass phase angle (lower limb), Fat-free Mass Index, and leg muscle score were aggravating factors for sarcopenia in both men and women. A receiver operating characteristic analysis of bone mass and sarcopenia status showed that the area under the curve and cut-off value, as well as its sensitivity and specificity, in men were 0.915 [95% confidence interval (CI): 0.853-0.977], 2.2 kg, 81%, and 87%, respectively, and 0.913 (95% CI: 0.858-0.968), 1.6 kg, 91%, and 88%, respectively, in women. This study revealed that the BIA method of measuring bone mass has excellent accuracy in detecting sarcopenia in both males and females.

Association between upper limb muscle quality and knee osteoarthritis in dynapenia: an observational cross-sectional study.

Neurological and skeletal muscle properties are suggested causes of dynapenia. This study aimed to evaluate the relationship between upper limb muscle quality (grip strength/upper extremity muscle mass) and knee osteoarthritis in dynapenia, and to identify dynapenia-associated factors. Elderly individuals who responded to a public call for screening in Wakasa Town, Fukui Prefecture between June 2019 and November 2021 were included. The analysis included 433 participants (304 women aged 76.0 ±â€…7.1 years). Examination comprised (consecutively) a basic interview, physical function measurement, body composition measurement, and explanation of results. Dynapenia was observed in 67 patients. Binomial logistic regression analysis revealed that age, upper limb muscle quality score, and knee osteoarthritis were independent factors for dynapenia. Receiver operating characteristic analysis of the relationship between dynapenia and upper limb muscle quality showed an area under the curve of 0.806 (95% confidence interval: 0.658-0.953) for men (cut-off value, 14.3 kg/kg) and 0.849 for women (95% confidence interval: 0.858-0.968; cut-off value, 14.0 kg/kg). In conclusion, age, upper limb muscle quality, and knee osteoarthritis were independent factors of dynapenia. We demonstrated that upper limb muscle quality has good accuracy in detecting dynapenia in both men and women.

Two cases of acute pulmonary artery embolism triggered by fresh and chronic mixed-vein thrombosis with a "Blowfish sign".

Ultrasonography and computed tomography of the lower extremities revealed fresh and chronic mixed-vein thrombosis (FCMVTs) presenting the "Blowfish sign," accompanied by pulmonary embolism. FCMVTs presenting the "Blowfish sign" may increase the risk of fatal pulmonary embolism, and its detection by ultrasonography is important for preventing pulmonary embolism.

Ultrasound cardiography examinations detect victims' long-term realized and potential consequences after major disasters: a case-control study.

BACKGROUND: An increase in cardiovascular diseases has been reported following major disasters. Previous work has shown that ultrasonographic findings from ultrasound cardiography examination (UCG) increased until the 44th month after the tsunami caused by the Great East Japan Earthquake. The present study conducted UCG among victims in the tsunami disaster area and investigated the frequency of disaster-related cardiovascular diseases and changes over time until the 55th month after the disaster. METHODS: The subjects were residents of temporary housing complexes and neighboring housing in Watari-gun, Miyagi Prefecture, Japan. There were 207 subjects in the 18th month, 125 in the 30th month, 121 in the 44th month, and 106 in the 55th month after the disaster. Data were collected through UCG and self-report questionnaire. RESULTS: Significant changes were observed among subjects with clinical findings from the UCG, which increased over the study period-from 42.0 to 60.8, 72.7, and 73.6% beginning in the 18th month after the disaster (p < 0.0001). CONCLUSIONS: It is possible that the UCG can become a useful examination to visualize the potential impact of a major disaster on the cardiac function of victims. Victims with clinical findings continued increasing not only during the acute phase after a disaster but also in the long term. We therefore need to keep this in mind, and note that it is important to establish a support system to control cardiovascular diseases from the early stage of disaster.

Individualized Nutritional Management Using Dishcook Improves Nutrition Status Markers in Patients with Intellectual Disability.

Dishcook is a new cooking system that allows individual cooking using a dedicated induction heater. This study investigated whether Dishcook use affects the nutritional value of individuals with intellectual disabilities. This study was conducted on users receiving support from a continuous-employment office in Obama City, Fukui Prefecture, in 2022. Of these participants, 18 (seven women and 11 men) who requested the use of the Dishcook were included in the analysis. The study period was from January to August 2023. The mean age was 48.72±16.24 y. A significant increase in the overall phase angles of the limbs was observed. Triglyceride, LDL cholesterol, HbA1c, and serum zinc levels improved in patients who used the Dishcook. The phase angle obtained using Bioelectrical Impedance Analysis also improved, indicating the usefulness of the Dishcook in treating metabolic diseases and the possibility of individualized nutritional management.

Long-Term Prevalence of Disaster-Related Deep Vein Thrombosis in Minamiaso Village After the 2016 Kumamoto Earthquakes: A Prospective Cross-Sectional Analysis.

OBJECTIVE: This study aimed to examine the prevalence of deep vein thrombosis (DVT) among evacuees in Minamiaso, a village which was temporarily isolated after the earthquakes, from the acute to recovery phase after the 2016 Kumamoto Earthquakes (GLIDE no: EQ-2016-000033-JPN). METHODS: This prospective study, which was approved by Fukui University Medical Research Ethics Committee (approval no. 20160024 and 20160089), enrolled 181 evacuees (73.9 ± 11.6 y) who participated in a series of 3 DVT screenings using portable ultrasound machines conducted over 19 mo. All participants completed a questionnaire before the screenings, and none of the participants attended all 3 screenings. Data analysis was performed using EZR version 1.41. RESULTS: The DVT prevalence was 14.3% (79.4 ± 8.2 y) at first screening of evacuees staying in shelters and 18.5% (71.5 ± 13.1 y) and 12.2% (72.8 ± 10.9 y) in second and third screenings of evacuees staying in temporary housing, respectively. Multivariate analysis revealed age ≥75 y and alcohol consumption as independent risk factors in the entire cohort and in patients aged ≤74 y, respectively. CONCLUSIONS: A high DVT prevalence over a long time period of 19 mo was observed where survivors were temporarily isolated after the disaster.

Localized Right Subclavian Artery Dissection Detected by Accident on an Ultrasound Examination: A Case Report and Literature Review.

Right subclavian artery dissection was detected in a 78-year-old female victim of the Kumamoto earthquake during a carotid artery ultrasound examination. She was subsequently taken to hospital and diagnosed with localized subclavian artery dissection (LSAD) by contrast-enhanced computed tomography. There have been no previous reports of LSAD detected at a medical checkup. LSAD may progress and become severe, even in asymptomatic patients or patients with mild symptoms, and careful long-term follow-up is therefore required in all patients diagnosed with LSAD.
