Consumption of meals prepared away from home is associated with inadequacy of dietary fiber, vitamin C and mineral intake among Japanese adults: analysis from the 2015 National Health and Nutrition Survey.

BACKGROUND: Consumption of home-prepared meals may lead to better nutritional intake. Few studies have examined the association between the frequency of consuming meals prepared away from home and the inadequacy of nutritional intake based on nutritional standards and food group intake. We therefore aimed to investigate this issue among Japanese adults. METHODS: This study was a secondary analysis of the 2015 National Health and Nutrition Survey in Japan, involving 921 men and 1300 women aged 18-64 years, conducted as a cross-sectional survey. The frequency of consuming meals prepared away from home was defined using two questions inquiring about the frequency of eating out and take-away meals. Data on dietary intake were collected using a one-day semi-weighed household dietary record. Participants were stratified into three groups based on the frequency of consuming meals prepared away from home (High, Moderate, Low). The inadequacy of each nutrient intake was assessed by comparing estimated average requirement (EAR) level for 14 nutrients and the range of the dietary goal (DG) for seven nutrients according to the 2015 version of the Dietary Reference Intakes for Japanese. Group differences in nutrients adequacy were assessed using the covariate and logistic regression analysis. Food intake was also compared across the groups by classifying each food item into 17 groups based on Standard Tables of Food Composition. RESULTS: The proportion of participants who consumed home-prepared meals almost every day were 34.9% among men and 46.8% among women, and the proportion of those consuming a higher frequency of meals prepared away from home were 14.7 and 6.3%, respectively. A higher frequency of consuming meals prepared away from home was associated with inadequacy of dietary fiber, vitamin C and minerals (iron, magnesium and potassium) intake, and with lower intake of vegetables and higher intake of fat and oils. CONCLUSIONS: High frequency of consuming meals prepared away from home was associated with insufficient intake of dietary fiber, vitamin C and multiple minerals among Japanese adults. These nutrients may be the potential target of interventions aimed at improving nutrient intake in individuals who predominantly eat food prepared away from home.

Analysis of risk factors for multidrug-resistant pathogens and appropriate treatment indications for pneumonia in children with neurologic impairment.

INTRODUCTION: The features of pneumonia in children with neurologic impairment (NI) resemble those of healthcare-associated pneumonia is defined as pneumonia occurring in the community associated with healthcare risk factors. There are currently no guidelines for the treatment of pneumonia in children with NI. Here, we assessed whether the guidelines applicable for treating pneumonia in adults could be applied to children with NI. METHODS: Between 2008 and 2019, we enrolled children with NI who developed pneumonia and were treated in the pediatric ward of Kawasaki Medical School Hospital. We evaluated patient characteristics, the frequency of isolation of multidrug-resistant (MDR) pathogens, and clinical outcomes. RESULTS: MDR pathogens were more frequently isolated from patients receiving tube feeding (TF) and/or with tracheostomy than from patients without these risk factors. Other risk factors, including a history of antibiotic therapy and methicillin-resistant Staphylococcus aureus isolation, recent hospitalization, residence in a nursing home or extended care facility, and low-dose, long-term macrolide therapy, did not significantly affect the frequency of MDR pathogen isolation. In patients receiving TF and/or with tracheostomy, treatment success was achieved in all cases treated with broad-spectrum antibiotics and 72.2% of cases treated with non-broad-spectrum antibiotics (P = 0.007). Conversely, among patients without these risk factors, no such difference was observed. CONCLUSIONS: Our findings indicate that the guideline to select antibiotics for treating pneumonia in children with NI should be simpler and more useful than the current guidelines for adult pneumonia, based on risk factor assessment for MDR pathogens.

Investigating interest in orthopedic surgery within an entire medical faculty: A cross-sectional study.

BACKGROUND: Discrepancies exist between the magnitude of musculoskeletal problems and the competency of physicians practicing musculoskeletal medicine, which likely stems from medical school-level educational deficiencies. Therefore, inadequate orthopedic surgery education during medical school may affect the number of students aspiring to practice orthopedic surgery. However, the motivating factors underlying medical students' selection of a career specialty are largely unknown. This study aims to use a survey to examine the motivations of medical students who consider orthopedic surgery as a potential career specialty. METHODS: A questionnaire survey was administered to medical students in our medical faculty. The results were stratified on the basis of gender, year, and experience as a patient; results were then compared between students who wished to practice orthopedic surgery and those who did not consider it a potential specialty. RESULTS: Of the 499 students who responded to the questionnaire, 47% considered orthopedic surgery as their career specialty. Being male and having experienced orthopedic surgery as a patient were significant factors influencing the aspiration to practice orthopedic surgery (p < 0.001). In addition, the motivation for choosing orthopedic surgery was academic interest for 55% of students. In the first and fifth years, more than half of the students preferred an orthopedic surgery specialty. The percentage of fifth-year students who were candidates for orthopedic surgery as their career specialty significantly exceeded that of students in other years (p = 0.03). However, the percentage of students considering orthopedic surgery decreased in the sixth year. CONCLUSION: Our findings suggest that orthopedic surgeons should provide a clearer, more informative job description to attract female medical students' attention and change their negative perception of orthopedic surgery. Furthermore, including education that incorporates experiences closer to clinical practice at the medical-school level is important for increasing the number of candidates for orthopedics.

Trends in BMI among elderly Japanese population: findings from 1973 to 2016 Japan National Health and Nutrition Survey.

OBJECTIVE: To examine 44-year trends in height, weight and BMI, and the prevalence of overweight/obesity and underweight in the elderly Japanese population because Japan, the country with the longest life expectancy, has the highest ageing population. DESIGN: Using the nationally representative cumulative data from the Japan National Health and Nutrition Survey 1973-2016, sex-specific and age-adjusted mean height, weight and BMI, and the prevalence of overweight/obesity and underweight were calculated for each year. Trend analyses were performed using the Joinpoint Regression Program. Next, changes in height, weight and BMI, and the prevalence of overweight/obesity and underweight were estimated for each age group (65-69, 70-79 and >80 years) according to the birth year groups. SETTING: Japan. PARTICIPANTS: Individuals aged ≥65 years with complete data on height and body weight measurements (N 94 508). RESULTS: Trends in average height and weight increased over the four decades in both men and women. The prevalence of overweight/obesity dramatically increased and nearly tripled in men, accompanied with significantly decreased underweight prevalence. Furthermore, the increasing trend in average BMI and overweight/obesity prevalence in women reached a peak in 2002 and showed a decreasing trend thereafter, while a downward trend in underweight prevalence showed a gradual increase in women since 2003. CONCLUSIONS: Trends in height, weight and BMI among the elderly population should continue to be closely monitored in parallel with the effects of dietary changes, energy intake and physical activity (step counts).

Comparing Antimicrobial Susceptibilities among Mycoplasma pneumoniae Isolates from Pediatric Patients in Japan between Two Recent Epidemic Periods.

We compared the antimicrobial susceptibility of Mycoplasma pneumoniae isolates from pediatric patients in Japan in 2011-2012 and 2015-2016, when epidemics occurred. The antimicrobial activity of macrolides and tetracyclines against M. pneumoniae infection tended to be restored in 2015-2016. There was no change in the antimicrobial activity of quinolones against M. pneumoniae infection.

Epstein-Barr Virus (EBV)-induced B-cell Lymphoproliferative Disorder Mimicking the Recurrence of EBV-associated Hemophagocytic Lymphohistiocytosis.

We describe the case of a 23-month-old male infant with Epstein-Barr virus (EBV)-associated lymphoproliferative disorder, which mimicked the recurrence of EBV-associated hemophagocytic lymphohistiocytosis. Chemotherapy with dexamethasone, etoposide, and cyclosporine resolved fever, hepatosplenomegaly, and pancytopenia. However, on day 81 of illness, the patient developed similar symptoms. Plasma EBV-DNA levels markedly increased again, but no T-cell clonality was observed. B cells were identified to be infected with EBV. He was successfully treated with rituximab, dexamethasone and etoposide. When recurrence of EBV-associated hemophagocytic lymphohistiocytosis is suspected, performing tests to identify the infected cells will enable accurate understanding of the clinical condition, resulting in proper treatments.

Nutrition knowledge related to breakfast skipping among Japanese adults aged 18-64 years: a cross-sectional study.

OBJECTIVE: Breakfast skipping is regarded as a public health issue among adults worldwide. Nutrition knowledge has been reported to be one of predictors of dietary behaviour. Therefore, the aim of the present study was to examine the association between nutrition knowledge and breakfast skipping. DESIGN: Data regarding nutrition knowledge were obtained by using a validated, self-administered general nutrition knowledge questionnaire for Japanese adults (JGNKQ). Participants were classified into three nutrition knowledge level groups according to total JGNKQ score: Low, Middle and High. In addition, participants reported the frequency of meal consumption per week and rated the difficulty in finding time to eat breakfast, lunch and dinner in the lifestyle questionnaire. The differences in frequency of breakfast, lunch and dinner consumption among Low, Middle and High nutrition knowledge groups were determined by using ANCOVA adjusted for potential confounding factors. SETTING: Kanto region, Japan.ParticipantsJapanese adults aged 18-64 years (n 1165, 57·3% women). RESULTS: Mean age of the participants was 43·8 (sd 8·9) years. There were no significant differences found in the proportion of respondents reporting difficulty in finding time to eat each meal among the three groups. However, the frequency of breakfast consumption was significantly different among Low, Middle and High groups, while lunch and dinner frequency did not differ among the three groups. CONCLUSIONS: The present study suggests that nutrition knowledge level is related to breakfast skipping among Japanese adults.

The trends in total energy, macronutrients and sodium intake among Japanese: findings from the 1995-2016 National Health and Nutrition Survey.

Monitoring nutritional status of the population is essential in the development and evaluation of national or local health policies. In this study, we aimed to demonstrate analysis on the trends in dietary intake of energy and macronutrients, as well as Na, in Japanese population using the data of series of cross-sectional national surveys - the National Nutrition Survey (NNS) and the National Health Nutrition Survey (NHNS) - during the period from 1995 to 2016. The NNS and NHNS participants aged 20-79 years were included in the analysis. Dietary intake was estimated using 1-d household-based dietary record. The trend in total energy intake, energy intake from macronutrients (fat and protein), Na intake and energy-adjusted Na intake were analysed using regression models adjusted to 2010 age distribution and anthropometry status. A total of 94 270 men and 107 890 women were included the analysis. Total energy intake showed a decreasing trend in both men and women. Similarly, energy intake from protein decreased, but energy intake (%) from fat increased in both sexes. Energy-adjusted Na intake showed a decreasing trend in both men and women. This study identified the decrease in total energy intake and energy intake from protein, whereas there were inverse trends in energy intake from fat among Japanese adults. Continued monitoring of trends in dietary intake will be needed, and there should be efforts to increase the accuracy of current survey procedures.

Incidence of Viremia With DNA Viruses in Oncology Patients With Febrile Neutropenia.

BACKGROUND: Although febrile neutropenia (FN) is one of the most common adverse events produced by chemotherapy, its microbiological etiology is determined for only 15% to 30% of cases. OBJECTIVES: We investigated the rate of viremia with common DNA viruses in patients with FN. STUDY DESIGN: From June 2012 to April 2014, 72 blood samples from 24 patients receiving chemotherapy, who experienced FN episodes, were examined for the presence of herpes viruses and other DNA viruses. We used real-time polymerase chain reaction assays to detect herpes simplex virus type 1 and 2, varicella zoster virus, Epstein-Barr virus, cytomegalovirus, human herpes virus types 6 and 7, BK virus and human parvovirus B19 (B19). RESULTS: Viruses were identified in 14 of 72 samples (19.4%). The detected etiological agents were BK virus (5 episodes), human herpes virus type 6 (4 episodes), B19 (4 episodes), Epstein-Barr virus (2 episodes), and cytomegalovirus (1 episode). CONCLUSIONS: Our results indicate that viral infections are common causes in patients with FN. Therefore, viruses may be responsible for FN in a large proportion of patients in whom a causative microorganism could not be identified, and this viral etiology may explain their poor response to antibiotic therapy.

Macrolide-Resistant Mycoplasma pneumoniae Infection, Japan, 2008-2015.

We evaluated isolates obtained from children with Mycoplasma pneumoniae infection throughout Japan during 2008-2015. The highest prevalence of macrolide-resistant M. pneumoniae was 81.6% in 2012, followed by 59.3% in 2014 and 43.6% in 2015. The prevalence of macrolide-resistant M. pneumoniae among children in Japan has decreased.

DIC Complicating APL Successfully Treated With Recombinant Thrombomodulin Alfa.

An 8-year-old boy developed anorexia, fatigue, and fever. Laboratory examination revealed a high white blood cell (WBC) count of 145×10/µL with 97.5% abnormal promyelocytic cells that contained Auer bodies. Faggot cells were seen. He was diagnosed with acute promyelocytic leukemia. Later, a chromosome analysis showed 46,XY,t(15;17)(q22;q12). Promyelocytic Leukemia-retinoic acid receptor α-fused gene and chimeric mRNA were confirmed by fluorescence in situ hybridization and reverse transcriptase polymerase chain reaction, respectively. He was complicated with disseminated intravascular coagulation (DIC) and his fibrin and fibrinogen degradation product at the onset was 37.6 µg/mL. Human recombinant thrombomodulin (rTM) was started for DIC. After dexamethasone was administered at a dose of 8 mg/m to prevent all-trans retinoic acid syndrome on day 1, all-trans retinoic acid was started at a dose of 45 mg/m on day 4. Cytarabine (100 mg/m/d) and daunorubicin (45 mg/m/d) were started on day 9. The WBC count gradually increased to 270×10/µL on day 8, and then decreased beginning on day 9. DIC improved after the initiation of chemotherapy and only minor petechia was noted. DIC did not become worse even after rTM was stopped on day 8. The risk of DIC and bleeding is high in the early stage of treatment for acute promyelocytic leukemia, especially in patients with a high WBC count. In our patient, rTM may have prevented fatal DIC and made it possible to safely administer induction chemotherapy.

Facile synthesis of the cyclohexane fragment of enacloxins, a series of antibiotics isolated from Frateuria sp. W-315.

An efficient and good yield synthesis of the cyclohexane moiety of enacyloxins, a series of antibiotics isolated from Frateuria sp. W-315, was achieved from d-quinic acid using a successive Barton-McCombie deoxygenation.

Perforating collagenosis.

We show a case of a 69-year-old man with perforating collagenosis, which is a rare dermatosis commonly associated with diabetes mellitus. Papules and plaques with keratotic plugs are distinctive clinical characteristic of perforating collagenosis. Representative clinical images in our article can enhance the understanding of key concepts of perforating collagenous.

Therapeutic efficacy of macrolides, minocycline, and tosufloxacin against macrolide-resistant Mycoplasma pneumoniae pneumonia in pediatric patients.

The importance of macrolide-resistant (MR) Mycoplasma pneumoniae has become much more apparent in the past decade. We investigated differences in the therapeutic efficacies of macrolides, minocycline, and tosufloxacin against MR M. pneumoniae. A total of 188 children with M. pneumoniae pneumonia confirmed by culture and PCR were analyzed. Of these, 150 patients had a strain with an MR gene and 134 had one with an A-to-G mutation at position 2063 of M. pneumoniae 23S rRNA domain V. Azithromycin (n = 27), clarithromycin (n = 23), tosufloxacin (n = 62), or minocycline (n = 38) was used for definitive treatment of patients with MR M. pneumoniae. Defervescence within 48 h after the initiation of antibiotic therapy was observed in 41% of the patients in the azithromycin group, 48% of those in the clarithromycin group, 69% of those in the tosufloxacin group, and 87% of those in the minocycline group. The average number of days of fever after the administration of antibiotic treatment was lower in the minocycline and tosufloxacin groups than in the macrolide groups. The decrease in the M. pneumoniae burden, as estimated by the number of DNA copies, after 48 to 96 h of treatment was more rapid in patients receiving minocycline (P = 0.016) than in those receiving tosufloxacin (P = 0.049), azithromycin (P = 0.273), or clarithromycin (P = 0.107). We found that the clinical and bacteriological efficacies of macrolides against MR M. pneumoniae pneumonia was low. Our results indicated that minocycline rather than tosufloxacin can be considered the first-choice drug for the treatment of M. pneumoniae pneumonia in children aged ≥ 8 years.

Nationwide surveillance of macrolide-resistant Mycoplasma pneumoniae infection in pediatric patients.

We conducted nationwide surveillance to investigate regional differences in macrolide-resistant (MR) Mycoplasma pneumoniae strains in Japan. The prevalence of MR M. pneumoniae in pediatric patients gradually increased between 2008 and 2012. Although regional differences were observed, high levels of MR genes were detected in all seven surveillance areas throughout Japan and ranged in prevalence from 50% to 93%. These regional differences were closely related to the previous administration of macrolides.

Quality of Internet information related to the Mediterranean diet.

OBJECTIVE: The present study aimed to evaluate the quality of Internet information on the Mediterranean diet and to determine the relationship between the quality of information and the website source. DESIGN: Website sources were categorized as institutional, pharmaceutical, non-pharmaceutical commercial, charitable, support and alternative medicine. Content quality was evaluated using the DISCERN rating instrument, the Health On the Net Foundation's (HON) code principles, and Journal of the American Medical Association (JAMA) benchmarks. Readability was graded by the Flesch Reading Ease score and Flesch-Kincaid Grade Level score. SETTING: The phrase 'Mediterranean diet' was entered as a search term into the six most commonly used English-language search engines. SUBJECTS: The first thirty websites forthcoming by each engine were examined. RESULTS: Of the 180 websites identified, thirty-two met our inclusion criteria. Distribution of the website sources was: institutional, n 8 (25 %); non-pharmaceutical commercial, n 12 (38 %); and support, n 12 (38 %). As evaluated by the DISCERN, thirty-one of the thirty-two websites were rated as fair to very poor. Non-pharmaceutical commercial sites scored significantly lower than institutional and support sites (P = 0.002). The mean Flesch Reading Ease score and mean Flesch-Kincaid Grade Level were 55.9 (fairly difficult) and 7.2, respectively. The Flesch-Kincaid Grade Level score determines the difficulty of material by measuring the length of words and sentences and converting the results into a grade level ranging from 0 to 12 (US grade level). CONCLUSIONS: Due to the poor quality of website information on the Mediterranean diet, patients or consumers who are interested in the Mediterranean diet should get advice from physicians or dietitians.

Self-reported rate of eating is significantly associated with body mass index in Japanese patients with type 2 diabetes. Japan Diabetes Clinical Data Management Study Group (JDDM26).

We examined whether the rate of eating was associated with the body mass index and glycemic control status in Japanese patients with type 2 diabetes (50% women, mean±SD age 59.4±7.5 years). Rapid eating was significantly associated with body mass index (p=0.047). The body mass index of those who reported eating quickly was 0.8 kg/m² higher than in individuals who reported eating at medium speed even after adjustment for known confounders. No significant association was observed between the rate of eating and HbA(1c). Our findings suggest an association between self-reported rapid eating and an elevated body mass index in patients with type 2 diabetes.

Association of Hours of Paid Work with Dietary Intake and Quality in Japanese Married Women: A Cross-Sectional Study.

This study investigated the association of hours of paid work with dietary intake and diet quality among Japanese married women. This cross-sectional study was a secondary analysis of a nationwide population survey in 2013. The analytic sample included 644 married women aged 20-59 years. The participants were categorized into five groups according to hours of paid work per week: 0 (housewives), 1-14, 15-34, 35-42, and ≥43 h. Dietary intake was assessed by a self-administered diet history questionnaire. The Nutrient-Rich Food Index 9.3 (NRF9.3) was used to measure the dietary quality. The association of hours of paid work with dietary intake and NRF9.3 score was assessed using a multivariable general linear regression analysis with adjustments for confounders. Hours of paid work were associated with a higher intake of rice and lower intake of vegetables, potatoes, soy products, and seaweeds and nutrients including protein, dietary fiber, and most vitamins and minerals. Hours of paid work were negatively associated with the NRF9.3 score. This study showed that Japanese married women engaging in paid work, especially those who work long hours, have less healthy diets. Efforts to improve the dietary intake of married women with paid work might be needed.

Associations Between Health Literacy and Underweight and Overweight Among Japanese Adults Aged 20 to 39 Years: A Cross-Sectional Study.

Background. Both underweight and overweight are public health concerns in Japan. Several studies examined the association between health literacy (HL) and obesity status in the general population; however, there is limited information on young adults. In addition, the association between HL and underweight status has not been extensively investigated. Aim. To examine the association between HL and underweight/overweight status among young Japanese adults aged 20 to 39 years. Method. This study was based on a cross-sectional survey of population-representative adults. HL was assessed using a questionnaire validated in Japanese adults. Body mass index (BMI) was calculated using self-reported weight and height. Participants were divided into two groups by HL score using the median score (lower vs. higher HL). The association between HL and underweight (BMI <18.5) or overweight (BMI ≥25.0) was examined using multinomial logistic regression analyses after adjusting for potential confounders. Results. In total, 476 women and 454 men were included in the analyses. Prevalence of underweight and overweight was 20.8% and 10.3% in women and 8.8% and 20.3% in men, respectively. In women, 45.1% of normal weight, 47.5% of underweight, and 30.6% of overweight had higher HL. Among men, 50.3% of normal weight, 35.0% of underweight, and 44.6% of overweight had higher HL. Bivariate analyses showed no statistically significant association between HL level and underweight/overweight status. Even after adjusting for potential confounders, these associations did not change. Discussion and Conclusion. This study suggests that HL scores may not be associated with underweight or overweight status in Japanese adults.
