OBJECTIVESThe aim of this study was to determine whether the serum nitrite plus nitrate (NO( x )) level correlates with biomarkers that are known components of the metabolic syndrome (MetS).

METHODSSerum NO( x ) levels were measured using a commercial kit in 608 Japanese men and women between the ages of 39 and 85 years. Multivariate adjustments for age, smoking status, alcohol consumption and exercise were made in the analysis of covariance (ANCOVA). The components of the metabolic syndrome were defined based on the following criteria: body mass index (BMI) >/=25.0 kg/m(2), glycated hemoglobin (HbA1c) >/=5.6%, systolic blood pressure >/=130 mmHg or diastolic blood pressure >/=85 mmHg, high-density lipoprotein-cholesterol (HDL-C) /=1.69 mmol/l.

RESULTSThe logarithmically transformed age-adjusted serum NO( x ) (lnNO( x )) value was significantly higher in the low HDL-C group (1.76 +/- 0.05 mumol/l; p < 0.05) than MetS component groups (1.65 +/- 0.01 mumol/l) in men, but no difference was found in women. The means of serum lnNO( x ) after multivariate adjustment were 1.64, 1.65, 1.64, 1.66, and 1.81 mumol/l for 0, 1, 2, 3, and 4-5 MetS components for all subjects, respectively. The results of ANCOVA confirmed that the serum lnNO( x ) level was significantly correlated with the clustering of MetS components in both men and women (p < 0.0001 for trend).

CONCLUSIONOur results suggest that an increase in the clustering of MetS components was associated with the increase in serum NO levels in our general population.

We evaluated the role of pharmacists in an interdisciplinary pain center using text mining analysis. We investigated 28 patients who visited an interdisciplinary pain center from May 2014 to July 2015. All patients were interviewed by a pharmacist. Further, we performed morphological analysis of medical records; classification of appearing words into “medicines/side effects,” “diagnosis/disease name,” “pain site,” “pain characteristics/concomitant symptoms,” “life/environment,” and “mental”; and correspondence analysis. The frequently appearing words “pain characteristics/concomitant symptoms” and “medicines/side effects” were used by 47.2% doctors and 35.3% pharmacists, respectively. In the correspondence analysis, doctors frequently referred to “pain characteristics/concomitant symptoms,” pharmacists frequently referred to “medicines/side effects,” and nurses frequently referred to “life/environment” and “pain site.” The fact that the three occupations used distinguishing phrases suggests that each is specialized in a distinct area. At an interdisciplinary pain center, we interviewed a nurse, a pharmacist, and a doctor, and shared information from various angles. The pharmacist focused on listening to the “medicines/side effects,” which is information related to his profession. Pharmacists contribute to medical care by recording information in medical records and sharing the information with other occupations. It is necessary to continue to provide information related to our specialized profession, respect each other, and provide high-quality medical care.

Objective  To identify issues in health communication regarding treatment support for foreign-born who are diagnosed as latent tuberculosis infection (LTBI) in Japan, from the perspective of public health centers (PHCs).Methods  A self-administered survey was sent to 469 PHC, between June and July 2020. The survey asked closed and open-ended questions to tuberculosis (TB) program personnel on (1) their experiences of foreign-born patients who were eligible for LTBI treatment but did not start their treatment, and who started treatment but were lost to follow-up, and (2) health communication issues with foreign-born patients. Responses were summarized descriptively for close-ended questions, and analyzed qualitatively for open-ended question.Results  We obtained response from 307 PHCs, regarding 315 foreign-born patients. Twenty-five patients did not initiate, and 52 were lost to follow-up after initiating LTBI treatment. Of the 77 patients who either did not start treatment or were lost to follow-up, 45 apparently could hold everyday conversation in Japanese but had difficulties understanding technical terms, and 19 could not even exchange basic conversation, with PHC staff. Barriers to LTBI treatment initiation and completement, as perceived by PHC staff, included “lack of correct knowledge about TB and LTBI”, “different attitudes to health” and “economic difficulties”. Conclusion  Issues in health communication between PHC staff and foreign-born patients included not only a language barrier, but also the unconscious mind among PHC staff, which sought reasons for refusal or termination of LTBI treatment in patients. We argue that this mind is based on positivism, whereby health personnel consider themselves as the provider of “scientific knowledge” and that “lay persons” can act rationally once enlightened. However, PHC staff may need to reflect upon such position as the provider of scientific knowledge, but instead, learn from foreign-born patients about how they perceive health, TB or LTBI, to conduct better communication.

Objective: This study aims to compare the epidemiology of notifications of latent tuberculosis infection (LTBI) among Japan-born and foreign-born children in Japan between 2010 and 2020, and to assess the language used during LTBI case interviews with parents or caregivers of foreign-born children with LTBI during 2019. Methods: Our study consisted of two parts: (1) an analysis of national data from the Japan Tuberculosis Surveillance (JTBS) system on the epidemiology of LTBI among Japan-born and foreign-born children in Japan and (2) a survey of staff at public health centres that had registered at least one foreign-born child aged <=14 years with LTBI. Data were extracted from the JTBS system for all children aged <=14 years who were newly notified as having LTBI between 2010 and 2020, and analysed to determine trends, characteristics and treatment outcomes. Staff at relevant public health centres completed a self-administered survey. Results: A total of 7160 Japan-born and 320 foreign-born children were notified as having LTBI between 2010 and 2020. Compared with Japan-born children, foreign-born children notified as having LTBI were more likely to be older, have their mother or sibling as their source of infection and have LTBI detected via a routine school health check. At case interviews, the use of language interpretation services was limited, even when both parents were non-Japanese. No interview was directly conducted with children themselves, not even with school-aged children. Discussion: Foreign-born children and their parents may be unfamiliar with the system of testing for TB infection and the diagnosis of LTBI in Japan in school settings. Public health centres are required to provide education to patients and their families and care that takes into account cultural and linguistic differences. However, the provision of language support during case interviews may need strengthening.
