Japanese school children's intake of selected food groups and meal quality due to differences in guardian's literacy of meal preparation for children during the COVID-19 pandemic.

In 2020, a state of emergency (SOE) was enforced by the Japanese government, which included temporary school closures with the aim of overcoming COVID-19 spread, which prevented access to school lunches. We evaluated the relationship between meal quality and guardians' literacy of meal preparation for a nationally representative sample of 1107 Japanese schoolchildren (aged 10-14 years) before, during, and after the SOE on the basis of 7 questions scored using a 5-point Likert scale. The guardians' literacy of meal preparation for children was divided into quartiles, with Q1 and Q4 including participants with the lowest and highest scores on food literacy, respectively. School lunch menu was handed out monthly to each household by their classroom teacher. The consumption of (i) meat, fish, or eggs and (ii) vegetables at least twice a day indicated "well-balanced dietary intake", which was less frequent in all four quartiles, especially for Q1 and Q2, during compared to before the SOE. The relative risk increases (95% CI) were Q1: -40.6% (-41.4% to -39.8%; p < 0.001), Q2: -34.0% (-34.7% to -33.3%; p < 0.001), Q3: -13.1% (-13.8% to -12.4%; p < 0.001), and Q4: -15.3% (-16.0% to -14.7%; p < 0.001), adjusted for sex, age, BMI, equivalent income adjusted for the number of household members, and educational level of parents. The interaction p was <0.001 for Q1-3 vs. Q4. Guardians with low total scores were significantly more likely to have less time, mental capacity, and financial ability to prepare meals after the SOE. Therefore, schoolchildren's meal quality deteriorated during the SOE, particularly among those with guardians with low food literacy even after adjustment for household income level and guardians' educational level.

[A Case of T-Cell Lymphoma Treated by Emergency Surgery Due to Bleeding of Jejunal Lesion].

A 78-year-old man was aware of lightheadedness and darkness at a routine outpatient visit, and his blood pressure was declined at 87/51 mmHg. Contrast-enhanced CT scan showed an extravascular leakage image at jejunum. We diagnosed as small intestinal hemorrhage. Because he was in hemorrhagic shock, emergency surgery was performed. A tumor was found coincident with the bleeding site, and partial resection of the small intestine including enlarged lymph nodes was performed. Based on the pathological findings of T-cell origin and positive for serum anti-HTLV-1 antibody, he was suspected as adult T-cell leukemia/lymphoma(ATLL). Endoscopic examination of the upper and lower gastrointestinal tracts, bone marrow examination, and PET-CT scan were performed, but no other lesions were found. We report a case of the T-cell lymphoma with suspected solitary ATLL of the jejunum.

Impact of the COVID-19 pandemic on food and drink consumption and related factors: A scoping review.

Background: The lockdown imposed due to the coronavirus disease (COVID-19) pandemic has caused several lifestyle changes. Aim: This scoping review aimed to report the present status of studies conducted on changes and factors related to food and drink consumption worldwide. Methods: Searches were performed in PubMed and EBSCO between August 6 and August 22, 2020 using the following criteria: (1) studies reporting changes in the current individual consumption of specific foods and snacks compared to that before the COVID-19 pandemic; (2) participants aged 18 years or older and without any diagnosable disease; and (3) articles that are peer-reviewed publications available in English. Studies were excluded if they involved an intervention related to diet or investigated the change in COVID-19 incidence. Results: Twelve articles were included in this review. The included studies revealed that there were various changes in food and drink consumption, such as the frequency and amount of consumption of snacks (n = 9), alcohol (n = 7), and vegetables and fruits (n = 5). These changes showed both increasing and decreasing trends. Of the 12 studies, 10 reported factors related to dietary changes, such as age, body mass index, psychological conditions, and residence; however, most of the results regarding these factors were inconsistent. Conclusions: Future studies should investigate long-term dietary changes and examine the factors that influence these changes to determine the pandemic's long-term impact.

Myoepithelioma of soft tissue and bone, and myoepithelioma-like tumors of the vulvar region: Clinicopathological study of 15 cases by PLAG1 immunohistochemistry.

We demonstrated the clinicopathological findings of 13 myoepitheliomas of soft tissue and bone (MESTBs) and two myoepithelioma-like tumors of the vulvar region (MELTVRs), focusing on the association between nuclear atypia and clinical course, and the utility of immunohistochemistry (IHC) of pleomorphic adenoma gene 1 (PLAG1) for the pathological diagnosis of these tumors. Of the 13 MESTBs, eight, one and four cases exhibited mild, moderate and severe nuclear atypia, respectively. Two cases with venous invasion showed severe nuclear atypia and both died of advanced disease. Two MELTVR cases showed moderate nuclear atypia and had no evidence of disease after surgery. On IHC, 12 of 13 (92.3%) MESTBs showed PLAG1 immunoreactivity and none of the MELTVRs expressed PLAG1. In addition, MELTVRs showed loss of INI1 expression. In contrast, all MESTBs retained INI1 expression. Fluorescence in situ hybridization detected EWSR1, FUS and PLAG1 rearrangement in 5 (38.5%), 0 (0%) and 2 (15.4%) of the 13 MESTBs, respectively. No EWSR1, FUS and PLAG1 rearrangement were observed in the METLVRs. In conclusion, MESTBs with both severe nuclear atypia and venous invasion would be indicative of malignant potential. PLAG1 might be a useful IHC marker in MESTB diagnosis.

Dietary diversity score correlates with nutrient intake and monetary diet cost among Japanese adults.

BACKGROUND AND OBJECTIVES: Dietary diversity is an indicator of diet quality. Dietary diversity has been suggested to result in good nutrient intake, but it can affect dietary cost. We examined whether dietary diversity correlates with nutrient intake and monetary diet cost. METHODS AND STUDY DESIGN: We used data for 3985 individuals (age range: 20-64 years) from the 2014 Japan National Health and Nutrition Survey (NHNS). Dietary diversity was assessed using the food variety score (FVS; the number of foods) and dietary diversity score (DDS; the number of food groups, range: 1-14). Mean energy and nutrient intake from NHNS, and diet cost from the National Retail Price Survey were compared among FVS quartiles using the Kruskal-Wallis test, and between 2 groups with median DDS using the Mann-Whitney U test. RESULTS: Mean (SD) FVS and DDS per day were 22.3 (7.2) and 9.8 (2.0), respectively. For most nutrients, intake per 4184 kJ was relatively high when FVS was high (p<0.001); however, carbohydrate intake was relatively high in the low-FVS group (p<0.001). For all nutrients with significant differences, intake was higher in the group with high DDS (≥10). Monetary diet cost was higher in the high-FVS and DDS groups compared with the low groups (p<0.001). CONCLUSIONS: Intake of a variety of food and food groups resulted in higher intake of various nutrients as well as higher monetary diet cost. Additionally, care should be taken to avoid excessive intake of nutrients such as sodium and SFA that may result from diverse diets.

Myoepithelioma-like tumor of the vulvar region showing infiltrative growth and harboring only a few estrogen receptor-positive cells: A case report.

Recently, a new entity "myoepithelioma-like tumor of the vulvar region (MELTVR)" was proposed as a rare mesenchymal neoplasm arising in vulvar regions of adult women. While MELTVRs morphologically resemble soft tissue myoepitheliomas and extraskeletal myxoid chondrosarcomas, they have a unique immunohistochemical profile (positive for epithelial membrane antigen and estrogen receptor, negative for S100 protein and glial fibrillary acidic protein, and loss of INI1/SMARCB1 expression), and lack EWSR1 and NR4A3 gene rearrangement, as seen by fluorescence in situ hybridization. MELTVRs are usually well-demarcated tumors, with no reports of extensive infiltrative growth. In the current report, we present an unusual case of MELTVR showing infiltrative growth and harboring only a few estrogen receptor-positive cells, which might indicate a variation in this rare tumor.

Pulmonary melanocytic nevus - A case report with a mutation analysis of common driver oncogenes.

Nevi are benign melanocytic tumors, and some nevi are considered to develop into malignant melanomas. Most nevi arise in the skin, but nevi occasionally occur in the conjunctiva, esophageal mucosa, or at other sites. Pulmonary melanocytic nevi are extremely rare, and only one case has been reported in the literature. Here, we present a case of pulmonary melanocytic nevus, involving a BRAF gene mutation (V600E), and we discuss the potential significance of this condition as a precursor to pulmonary malignant melanoma.

Barriers to accurately measuring patients' dietary intake in hospitals using the visual estimation method.

Purpose Visual estimation, an easy-to-perform technique, is commonly used in hospitals to assess dietary intake in patients. The authors performed a qualitative study where the authors interviewed nurses and dietitians about their perceptions of barriers to accurately measuring patients' dietary intake in hospitals using the visual estimation method. The paper aims to discuss these issues. Design/methodology/approach Ten dietitians and ten clinical nurses responded to 30-minute individual interviews in Tokyo, Japan, in September 2014. Each interview was conducted using a common protocol of open-ended questions focusing on the challenges of the visual estimation method and barriers to accurately measuring patients' dietary intake as part of their routine work. The tape-recorded interviews were transcribed and analyzed based on grounded theory. Findings Five main categories emerged: hospitals, meals, colleagues, raters, and patients. Various individual barriers such as skill, attitude, knowledge, and others that had not been considered in previous studies also emerged. External barriers that were out of the raters' control, such as shortage of time, human resources, financial ability, and others, emerged from the "hospitals" category. Research limitations/implications Research participants were all females and many of them had less than ten years of experience. Practical implications In addition to standardizing the visual estimation process, medical staff need to overcome various other internal and external barriers to accurate measurements. Originality/value This is the first study to articulate some important barriers that influence reliability and validity when measuring patients' dietary intake by visual estimation methods in typical clinical settings.

Solubilization of n-alkylbenzenes into gemini surfactant micelles in aqueous medium.

Solubilization of benzene, toluene, ethylbenzene, n-propylbenzene, n-butylbenzene, and n-pentylbenzene into micelles of decanediyl-1-10-bis(dimethyltetradecylammonium bromide) (14-10-14,2Br(-)) has been investigated in the temperature range from 288.2 to 308.2 K. The equilibrium concentrations of all the solubilizates are determined spectrophotometrically. The concentration of the solubilizates remains constant below the critical micelle concentration (cmc) and increases linearly with an increase in 14-10-14,2Br(-) concentration above the cmc. Compared to the mother micelle, the solubilized micelles indicate much larger hydrodynamic diameters, which are determined by dynamic light scattering. Therefore, the Gibbs energy change for the solubilization of n-alkylbenzenes has been evaluated by the partitioning of the solubilizates between the aqueous and micellar phases. Furthermore, the enthalpy and entropy changes for the solubilization could be calculated from temperature dependence of the Gibbs energy change. From the thermodynamic parameters, it is found that the solubilization for the present system is entropy-driven and that the location of the solubilizates moves into the inner core of the micelle with an elongation of their alkyl chains. The movement on the location is also supported by the results of absorption spectra, Fourier transform infrared (FTIR) spectra, and two-dimensional nuclear Overhauser effect spectroscopy (2-D NOESY).

Successful excision of an inflammatory endobronchial polyp using biopsy forceps with improvement in FEV1 in a patient with allergic bronchopulmonary aspergillosis: A case report.

Inflammatory endobronchial polyps (IEPs) are rare, benign bronchial tumors posing diagnostic and therapeutic challenges owing to limited data. A 55-year-old man, receiving treatment for allergic bronchopulmonary aspergillosis, presented with a one-week history of fever and purulent sputum. Diagnosed with pneumonia, he received antimicrobial treatment. However, because of persistent symptoms, an endobronchial tumor was suspected on computed tomography. IEP was confirmed through flexible bronchoscopy with forceps biopsy, and polyp removal improved symptoms, lung function, and imaging.

A case of urothelial carcinoma, lipid cell variant.

The lipid cell variant of urothelial carcinoma is a rare variant of urinary bladder cancer, comprised of lipoblast-like cells. In this report, we describe a case of the lipid cell variant of aggressive urothelial carcinoma. A 78-year-old man was admitted to the hospital because of gross hematuria. On cystoscopy, an ulcerative lesion, non-papillary architecture, was observed in the lateral wall of the bladder. Transurethral resection was performed. Histopathological findings of the bladder tumor indicated neoplastic cells forming irregular solid nests and sheets. Lipoblast-like neoplastic cells that had eccentric nuclei and cytoplasmic vacuoles were observed, not only in the resected specimen, but also in urine samples. On mucin histochemistry, the tumor cell cytoplasm contained no neutral or acidic mucus. The lipoblast-like cells were positive for cytokeratins (AE1/AE3, CK7) and adipophilin, known as a protein associated with neutral lipid synthesis. In general, it is difficult to prove the existence of intracytoplasmic lipid in formalin-fixed paraffin-embedded materials. This is the first report in which the presence of lipid in vacuoles of the lipid cell variant has been verified by immunohistochemistry.

Changes in Selected Food Groups Consumption and Quality of Meals in Japanese School Children during the COVID-19 Pandemic.

In 2020, a state of emergency was declared to control the devastating impact of coronavirus, leading to temporary school closures in Japan, meaning that school lunches were not provided to the majority of schoolchildren. Using questionnaires completed by participants' guardians, we examined the relationship between household income and the quality of meals in Japanese schoolchildren before, during, and after the state of emergency. Participants (1111 children, 10-14 years old) were chosen to form a nationally representative sample of the Japanese population. "Well-balanced dietary intake" was defined as the intake of (i) meat, fish, or eggs and (ii) vegetables. The desired prevalence was defined as equal to or more than twice a day. Household income was divided into quartiles. "Well-balanced dietary intake" was lower in all households during the state of emergency compared with before. The proportion of those with a "well-balanced dietary intake" at least twice a day was notably low in both Q3 and Q4 during the state of emergency compared with before the declared state of emergency; relative risk increase (95% CI) were Q1: -19.0% (-19.6% to -18.4%), p < 0.001, Q2: -21.3% (-22.1% to -20.6%) p < 0.001, Q3: -25.4% (-26.1% to -24.7%), p < 0.001, and Q4: -34.8% (-35.6% to -34.0%), p < 0.001. The interaction p (vs. Q1) of Q2, Q3, and Q4 were all <0.001. Guardians from low-income households had significantly higher rates of having less: time, psychological room, and financial position to prepare meals during the state of emergency. Our results suggest that schoolchildren's quality of meals worsened during the state of emergency, especially in low-income households, because school lunches were not provided.

Factors Associated with Dietary Change since the Outbreak of COVID-19 in Japan.

In Japan, dietary habits have greatly changed since the coronavirus disease (COVID-19) outbreak; we examined factors related to dietary changes. An online cross-sectional questionnaire survey was conducted in November 2020 among 6000 Japanese adults (aged 20-64 years) registered with a research company and gathered data on demographics, socioeconomic factors, medical history, COVID-19 status of the respondent's family and neighbors, fear of COVID-19, and changes in lifestyle and dietary habits since the COVID-19 outbreak. To the question "Have you made healthier changes to your dietary habits compared with the dietary habits before the spread of COVID-19 (1 year ago, November 2019)?", 1215 (20.3%), 491 (8.2%), and 4294 (71.6%) participants answered that their dietary habits were healthier, unhealthier, and unchanged, respectively. Healthier and unhealthier dietary habits were associated with greater fear of COVID-19, altered exercise and sleep times, and smoking. Unhealthy habits were positively associated with living alone, decreasing household income, colleagues with COVID-19, stress, and weight loss/gain. Annual household income, changing household income, COVID-19 in friends, health literacy, exercise frequency, weight loss, and starting smoking were positively associated with healthier dietary changes. The generalizability of these results and strategies to inculcate healthy diets in this "new normal" should be investigated.

Analysis of the expression and localization of tight junction transmembrane proteins, claudin-1, -4, -7, occludin and JAM-A, in human cervical adenocarcinoma.

OBJECTIVE: Tight junction proteins have recently been reported to be useful for distinguishing between neoplastic and non-neoplastic tissues. In this study, we evaluated the expression and localization of tight junction transmembrane proteins in human cervical adenocarcinoma and adenocarcinoma in situ (AIS), and we determined whether their expression patterns could distinguish cervical adenocarcinoma from non-neoplastic cervical glands. METHODS: Fifty-five patients with cervical adenocarcinoma or AIS were included in this study. Surgical specimens were immunohistochemically stained for claudin (CLDN) -1, -4, -7, occludin, and JAM-A. RESULTS: Significantly higher expression levels of CLDNs and JAM-A were found in cervical AIS and adenocarcinoma than in non-neoplastic glands. In cervical AIS and adenocarcinoma, localization of CLDN1 and JAM-A was extended throughout the whole cell membranes, whereas they were predominantly expressed at the most apical cell-cell junction in non-neoplastic glands. ROC curve analysis revealed that immunoreactivities of CLDN-1 or JAM-A successfully distinguished neoplasms from non-neoplastic cervical glands with high specificity (CLDN-1, 79.1%; JAM-A, 79.1%) and high sensitivity (CLDN-1, 84.1%; JAM-A, 95.5%). CONCLUSIONS: As expected, there were immunohistochemical differences between cervical adenocarcinoma and non-neoplastic cervical glands by using antibodies against tight junction transmembrane proteins. These results suggest that CLDN-1 and JAM-A are potential biomarkers for cervical adenocarcinoma.
