BACKGROUND:
Deterioration in lifestyle associated with poor mental health could be an important concern during the coronavirus disease 2019 (COVID-19) pandemic. However, few studies have investigated the association between mental health status and lifestyle changes during the pandemic in nationwide Japanese general population.
METHODS:
This cross-sectional study was conducted using the data among 1,546 participants of the follow-up study of NIPPON DATA2010 in 2021. Recent mental status, as assessed using the Kessler 6 (K6) scale, and lifestyle changes compared to before the pandemic were determined using self-reported questionnaires. Some lifestyle changes such as decreased physical activity were defined as undesirable, whereas others such as decreased alcohol drinking were defined as desirable. The participants were divided into three groups based on the K6 scores: the K6<5, 5≤K6<9, and K6≥9 groups. The odds ratios (ORs) and 95% confidence intervals (CIs) of the K6 groups for each lifestyle change compared with that in the K6<5 group were estimated after adjusting for possible confounders.
RESULTS:
The ORs of the K6≥9 group for all undesirable lifestyle changes were significantly high, especially increased alcohol drinking (OR 4.64; 95% CI, 2.71-7.93), and decreased physical activity (OR 4.63; 95% CI, 3.29-6.52). Among the desirable changes, the OR of the 5≤K6<9 group was significantly high for increased eating home cooking.
CONCLUSIONS
Poor mental health showed a significant association with undesirable lifestyle changes, especially increased alcohol drinking and decreased physical activity, in a nationwide general Japanese population during the COVID-19 pandemic.

The current study examined the antimicrobial resistance of Chlamydia Trachomatis (CT) genital infection during pregnancy in Japan. We requested 2,146 obstetrical facilities that are members of Japan Association of Obstetricians and Gynecologists to provide information of CT screening tests and antimicrobial resistance in pregnant women between April 2020 and March 2021. The prevalence of CT genital infection in Japan was 2.1%. The antimicrobial resistance was recognized in 2.0 and 2.4% of the cases using azithromycin and clarithromycin, respectively. There were no significant differences in the antimicrobial resistance rate between the 2 analogues (P = 0.28). In Japan, azithromycin and clarithromycin have effectively treated genital CT infections during pregnancy.

Distigmine has reversible and persistent cholinesterase (ChE) antagonism, and is used for the dysuria due to low activity bladders such as the neurogenic bladder dysfunction widely postoperatively, but fatal cases were reported by cholinergic syndrome. Therefore a dose was limited to 5mg only for adaptation of “the dysuria due to hypotonic bladder such as after surgery and the neurogenic bladder dysfunction” in March, 2010. In the current study, we examined a ministerial policy in the package insert revision using Japanese Adverse Drug Event Report database (JADER). Using a side effect report registered with JADER from January, 2004 to June, 2016, we calculated Reporting Odds Ratio (ROR) which was the index of the safe signal of the medical supplies adverse event and we compared number of reports and ROR of the cholinergic syndrome by the distigmine in approximately the measure in March, 2010 and evaluated it. The number of reports of the cholinergic syndrome by the distigmine was 138 cases before March 2010 and 65 cases after March 2010. After a measure, the number of reports decreased. The possibility that the package insert revision of the distigmine contributed to a decrease in cholinergic syndrome onset was suggested. Whereas monitoring careful sequentially needs the onset of the cholinergic syndrome in constant frequency to be found.

BACKGROUND:
The gender-specific characteristics of individuals at an increased risk of developing depression currently remain unclear despite a higher prevalence of depression in women than in men. This study clarified socioeconomic and lifestyle factors associated with an increased risk of subclinical depression in general Japanese men and women.
METHODS:
Study participants were residents not receiving psychiatric treatments in 300 sites throughout Japan in 2010 (1152 men, 1529 women). Multivariable-adjusted odds ratios (OR) and 95% confidence intervals (95%CIs) for socioeconomic factors and lifestyle factors were calculated using a logistic regression analysis.
RESULTS:
Risk of depressive tendencies was significantly higher in men who were single and living alone (OR, 3.27; 95% CI, 1.56-6.88) than those married. The risk was significantly lower in women who were not working and aged ≥ 60 years (OR, 0.39; 95% CI, 0.22-0.68) and higher in men who were not working and aged < 60 years (OR, 3.57; 95%CI, 1.31-9.72) compared with those who were working. Current smoking was also associated with a significantly increased risk of depressive tendencies in women (OR, 2.96; 95% CI, 1.68-5.22) but not in men.
CONCLUSIONS
Socioeconomic and lifestyle factors were associated with an increased risk of depressive tendencies in general Japanese. Related factors were different by sex.

In order to investigate the effects of fruits granola intake on defecation and quality of life (QOL), 20 females (mean age: 20.0 ± 1.1 y.o.) with frequency of defecation of less than 5 times per week were selected for this open study. Daily intake of 50 g of fruits granola was used as a substitute staple food for 2 weeks, and changes in defecation and QOL were compared before and after the procedure. The results showed that, compared with the pre-intake period, the frequency of defecation and the amount of defecation increased after fruits granola intake (p = 0.014, p = 0.024), and improvement of QOL (p = 0.011) was also observed. We conclude that, a continuous intake of fruits granola can improve defecation, and also improve quality of life.

The purpose of this study was to examine the health-related Quality of Life (QOL) of women and the effects of “fruits granola” on women’s health. It was based on an Internet questionnaire survey on QOL (using a QOL questionnaire for women that was prepared by LSTT Co., Ltd.) of 3,460 subjects who answered questions concerning physical and mental matters. It also had 165 subjects, 108 of whom had mild constipation and 57 of whom did not, consume fruits granola freely for a period of time and then compared their QOL before and after consumption.The results of the screening survey showed significantly higher scores in all categories among women who did not have constipation than women who did. Additionally, the mental QOL score was significantly higher among women who had the habit of eating fruits granola.Moreover, the overall QOL score significantly increased after consumption of fruits granola. These results suggest that consumption of fruits granola may be effective in improving women’s QOL.

Folic acid contained in potato (Solanum tuberosum L.) tubers is concentrated in potato chips by dehydration during frying. It is a vitamin recommended to young women which helps protect fetus from congenital disease. Additionally, folic acid can lower plasma homocysteine concentrations, a known independent risk factor for cardiovascular disease. This study was designed to determine whether the dietary consumption of potato chips affect serum folic acid concentration and plasma homocysteine concentration in human subjects. Results showed a significant increase in serum concentrations of folate 1, 3, and 6 hours after ingestion. Vitamin B6, on the other hand, increased significantly after 3 hours of intake. In contrast, plasma homocysteine concentration decreased significantly 6 hours after ingestion. These results suggest that potato chips would be a good dietary source of folic acid for humans.

To seek longitudinal changes in metacognitive processes through problem-based learning (PBL), we analysed the contents of all comments written reflectively by the third-year students after they finished discussions in each PBL session. After dividing their comments into meaningful units, we focused on two major thematic categories and five sub-categories to be analysed.
1) The number of units decreased significantly (chi-square: p=0.02).
2) Only the proportion of units categorised as “comprehension” in “individual learning” showed significant increase (Bonferroni: p<0.001).
3) Comments in this category stated that “I don't understand so-and-so.”
4) The increase of “comprehension” as they experienced more PBL suggested that students' knowledge of ignorance as metacognition was fostered through sessions in medical PBL.

OBJECTIVESExposure misclassification is a major obstacle to obtain accurate dose-response relationships. In order to solve this problem, the impact of hair treatment on total mercury in hair was assessed in Japanese women.
METHODSA cross-sectional study was carried out among 327 women at age 24-49 years to determine hair mercury levels and estimate daily mercury intakes from seafood by using a food frequency questionnaire.
RESULTSHair mercury levels in the women and daily mercury intake ranged from 0.11 to 6.86 (median 1.63) μg/g and from 0.77 to 144.9 (median 15.0) μg/day, respectively. The hair mercury was positively correlated with the daily mercury intake (p<0.001). When the women were divided into two subgroups based on artificial hair-waving, hair coloring/dyeing, residence (non-fishing and fishing areas), and working status, a significant difference in the hair mercury level was observed between the women with and without artificial hair-waving only (p<0.001). The multiple regression analysis showed that the log-transformed hair mercury level was significantly related to the log-transformed daily mercury intake (standardized regression coefficient βs=0.307) and artificial hair-waving (βs=-0.276); but not to hair coloring/dyeing, residence, working status or age. Permanent hair treatment was estimated to reduce total mercury in hair by approximately 30%, after adjusting for daily mercury intake and other possible factors.
CONCLUSIONSThese findings suggest that hair mercury is not the best biomarker of methylmercury exposure when a study population includes women with artificial hair-waving.
