    Objective Sarcopenia is a common secondary muscle-related complication observed in patients with chronic liver disease (CLD), along with muscle cramping. The present study aimed to assess the daily activity levels to explore the relationship between the number of steps taken and muscle cramping in patients with liver cirrhosis (LC) in Japan.

    Methods Fifty patients were enrolled (male 25, Child-Pugh A, B=42:8). Daily steps were recorded over six months using a pedometer, and seasonal sub-analyses were performed. Sarcopenia was diagnosed in accordance with the guidelines of the Japan Society of Hepatology.

    Results The median number of steps per day was 3,881, with no significant seasonal differences. Muscle cramping, reduced handgrip strength and sarcopenia were noted in 66.0%, 34.0% and 23.9% of the patients, respectively. However, no significant relationships were found between muscle cramping, handgrip strength, and the average number of steps per day. Although no significant differences in daily steps were noted in the comparisons of patients with varying degrees of hepatic function or the sarcopenia status, those with muscle cramping had a worse modified ALBI grade (≥2b) than those without (42.4% vs. 5.9%, p=0.009). The median average number of steps per day was not significantly different between the patients with and without muscle cramping (3,673 vs. 4,775, p=0.292).

    Conclusion The present study revealed that the average number of steps per day in LC patients is low. Although no significant relationship between daily activity and muscle cramping was observed, the establishment of appropriate intervention strategies to maintain daily activity and prevent sarcopenia progression is urgently required.

    Objective Although chronic kidney disease (CKD) is independently associated with hypertension or hyperglycemia, there is no consensus on the thresholds of obesity, dyslipidemia, or visceral fat accumulation to predict CKD onset and progression.

    Methods We performed a multivariable logistic regression analysis for the association of the subsequent rate of estimated glomerular filtration rate (eGFR) decline with body mass index (BMI), blood high-density lipoprotein (HDL) cholesterol and triglycerides (TG) levels on 308,174 subjects who underwent health examinations conducted by the Public Health Research Center Foundation from 2015 to 2022. In addition, a Poisson regression analysis was used to evaluate the association between the appearance of urinary protein in participants without baseline urinary protein levels and eGFR decline.

    Results The median age of the subjects was 46 years old, and the median observation period was approximately 3 years. An eGFR decline rate of ≥5%/year was significantly associated with low HDL-cholesterol levels (<40 mg/dL), independent of the BMI and TG levels. A high baseline BMI (≥25 kg/m2) or waist circumference (≥85 cm for men and ≥90 cm for women), high TG levels (≥150 mg/dL), and low HDL-cholesterol levels were significantly associated with new-onset proteinuria. Furthermore, the higher the baseline BMI, the higher the incidence rate ratio of new-onset proteinuria.

    Conclusion Independent of hyperglycemia and hypertension, dyslipidemia according to the Japanese metabolic syndrome criteria and an elevated BMI were associated with a high risk of new-onset proteinuria, and a low HDL-cholesterol level was significantly associated with a rapid eGFR decline.

    Objective Bacteria in the airways are reportedly involved in the pathogenesis of chronic obstructive pulmonary disease (COPD) and asthma. In addition, oral bacteria are thought to contribute to respiratory diseases by migrating to the airway. Therefore, we investigated whether or not the number of oral bacteria influences COPD, asthma, and asthma and COPD overlap (ACO).

    Methods We analyzed the correlations between the number of oral bacteria and clinical variables, such as pulmonary function tests, in patients with COPD, asthma, and ACO whose condition was stable and who visited our center from August 2019 to December 2020. The number of oral bacteria was assessed using the dielectrophoretic impedance measurement method.

    Results In patients with COPD (n=50), the number of oral bacteria was significantly negatively correlated with the percentage predicted forced expiratory volume in one second (%FEV1), percentage peak expiratory flow, and percentage forced vital capacity but was not correlated with the COPD Assessment Test. In patients with asthma (n=32), it was significantly negatively correlated with the FEV1 percentage and with the increase in FEV1 in the reversibility test but not with fractional exhaled nitric oxide. In patients with ACO (n=39), we found no significant correlation between the number of oral bacteria and any clinical variable.

    Conclusion The results suggest that the number of oral bacteria is associated with both lung capacity and airflow obstruction in patients with COPD and with airflow obstruction in patients with asthma.
