Mealtime Regularity Is Associated with Dietary Balance among Preschool Children in Japan—A Study of Lifestyle Changes during the COVID-19 Pandemic

The novel coronavirus-19 (COVID-19) pandemic has considerably impacted children’s lives. The aim of this study was to determine whether the pandemic affected mealtime regularity among preschool children and whether maintaining regular mealtimes or changes in mealtime regularity during the pandemic were related to dietary balance, including chronological relationships. This online cross-sectional survey involving individuals registered with a company that provides meals to children aged 2−6 years was conducted in February 2021. Using a 40-point scale, a healthy diet score (HDS) was developed to evaluate children’s dietary balance. The participants were divided into four groups based on their responses, and multiple regression analyses were performed with the HDS as the dependent variable. Maintaining regular mealtimes was associated with practices such as waking and going to bed earlier, less snacking, and eating breakfast every day. Even after adjusting for basic attributes, lifestyle habits, household circumstances, and other factors, regular mealtimes were still positively correlated with the HDS. These findings indicate that maintaining regular mealtimes is associated with higher HDS scores and better lifestyle habits. Furthermore, as the changed HDS was higher in the group whose mealtimes became regular during the pandemic, adopting regular mealtimes may lead to a more balanced diet.     

Clinical Characteristics Associated with the Development of Diabetic Ketoacidosis in Patients with Type 2 Diabetes

Objective This study analyzed the clinical and laboratory parameters that might influence the clinical outcomes of patients with type 2 diabetes who develop diabetic ketoacidosis (DKA), which has not been well investigated. Methods We reviewed the clinical and laboratory data of 158 patients who were hospitalized due to DKA between January 2006 and June 2019 and compared the data of patients stratified by the type of diabetes. In addition, the patients with type 2 diabetes were subdivided according to age, and their clinical and laboratory findings were evaluated. Results Patients with type 2 diabetes had a longer symptom duration associated with DKA, higher body mass index (BMI), and higher C-peptide levels than those with type 1 diabetes (p＜0.05). Among patients with type 2 diabetes, elderly patients (≥65 years old) had a longer duration of diabetes, higher frequency of DKA onset under diabetes treatment, higher effective osmolarity, lower BMI, and lower urinary C-peptide levels than nonelderly patients (＜65 years old) (p＜0.05). A correlation analysis showed that age was significantly negatively correlated with the index of insulin secretory capacity. Conclusion Patients with DKA and type 2 diabetes had a higher BMI and insulin secretion capacity than those with type 1 diabetes. However, elderly patients with type 2 diabetes, unlike younger patients, were characterized by a lean body, impaired insulin secretion, and more frequent DKA development while undergoing treatment for diabetes.     

Genotoxicity studies of glycidol fatty acid ester (glycidol linoleate) and glycidol

Glycidol fatty acid esters (GEs) are found in refined edible oils. Safety concerns have been alleged due to the possible release of glycidol (G), an animal carcinogen.     

Cytomegalovirus reactivation in patients with multiple myeloma

The introduction of novel antimyeloma agents has improved the outcome of multiple myeloma (MM) dramatically. However, it has also led to an increasing incidence of Herpesviridae family virus infections, including a high incidence of post‐transplant cytomegalovirus (CMV) reactivation after treatment with novel agents. We herein retrospectively assessed the CMV reactivation in all 120 newly diagnosed patients with MM consecutively seen and treated at our hospital. CMV antigenemia tests were ordered in 58 patients depending on the clinical context, and the incidence of CMV reactivation and proven/suspected CMV disease requiring antiviral therapy was 20% (24 of 120) and 11% (13 of 120) respectively, including those without stem cell transplantation (SCT). The clinical and laboratory characteristics of these patients were compared with those in 34 CMV antigenemia‐negative (CMV‐negative) patients. Patients with extramedullary disease or a low absolute lymphocyte count (ALC) had a higher risk of developing CMV reactivation. In addition, the median duration from the time of MM diagnosis to CMV reactivation was 5.0 months. These results suggest that, regardless of whether or not undergoing SCT, elderly patients with MM receiving novel agents should be monitored for CMV reactivation to allow for the timely diagnosis and treatment, especially for those with extramedullary disease.     

Application of the fracture risk assessment tool (FRAX®) and determination of suitable cut-off values during primary screening in specific health check-ups in Japan

Specific health check-ups, which do not include osteoporosis screening, are conducted more frequently than periodic osteoporosis screening in Japan. In this study, we investigated the usefulness of the fracture risk assessment tool (FRAX^®) during specific health check-ups, evaluated the variations in its usefulness for 2 consecutive years, and determined FRAX^® cut-off values for osteoporosis screening. FRAX^® questionnaires were distributed to subjects who underwent specific health check-ups in 2009 and 2010 at Asahi-machi. Subjects who exhibited FRAX^® cut-off values of ≥10 % were advised to be screened at a medical institution. Bone mineral densities (BMDs) were measured in 201 subjects in 2009 and 105 subjects in 2010 after specific health check-ups, and treatment was initiated for 79 subjects in 2009 and 24 subjects in 2010. The number of subjects examined and the rate of treatment initiation following specific health check-ups were higher than those in subjects following periodic osteoporosis screening in 2009. However, the number and the rate following specific health check-ups dropped in 2010. According to receiver operating characteristic curves analyses, the sensitivity and specificity of FRAX^® to determine osteoporosis treatment were highest when the cut-off values were 8 % for men and 10.5 % for women. In conclusion, the combination of FRAX^® and specific health check-ups was more useful than periodic osteoporosis screening to narrow down the subjects and to motivate them to seek follow-up. Cut-off values for specific health check-up using FRAX^® should be approximately 8 % for men and 10.5 % for women     

Endoscopically proven case of rapid esophagogastric variceal progression and rupture as a result of portal hypertension with liver sarcoidosis

Sarcoidosis is a multi‐systemic disease of unknown etiology that results in the development of non‐caseating epithelioid granulomas. The liver is the third most frequently involved organ after the lymph nodes and the lungs. Most cases of liver sarcoidosis do not present with symptoms and involve minimal liver dysfunction, but some cases display progression to portal hypertension and liver cirrhosis, and finally to liver failure. The mechanism and the risk of progression in liver sarcoidosis are still unknown because of the diagnostic difficulty associated with this condition, and because follow‐up examinations can only be done in an invasive manner. Here, we present an informative case of liver sarcoidosis with rapid progression of esophagogastric varices. Four months prior to the definitive diagnosis, no signs of varices were observed on endoscopy, and developmentof esophagogastric varices, rapid progression, and eventual rupture occurred in a short period of time. A liver biopsy, carried out after endoscopic sclerotherapy, revealed that granulomas primarily affected the portal area without fibrotic and cirrhotic changes, which is considered a primary cause of portal hypertension and esophagogastric varices. Following the liver biopsy, the patient was given systemic steroids and is currently receiving outpatient care. Thus, we should consider the possibility that liver sarcoidosis, even in the absence of cirrhotic changes, can cause serious events such as esophagogastric variceal rupture following rapid progression as a result of portal hypertension.
