Background: This study aimed to evaluate the relationship between disease type and healthcare-seeking behavior in patients in order to assess the role of primary care in rural areas of Japan.
Methods: National Health Insurance receipt data were collected for outpatients from four towns in Hokkaido, Japan. Disease names were encoded using the International Classification of Primary Care-2 (ICPC-2) coding system. Patient data were divided into two categories: those visiting medical facilities in their own towns and those visiting medical facilities in other towns.
Results: The percentage of patients who visited medical facilities outside their own town ranged from 42.9% to 72.7%; the mean value for all four towns was 54.6%. The three most frequent ICPC-2 codes according to the reimbursement receipts were K86 (hypertension, uncomplicated), T93 (lipid disorder), and T90 (diabetes, noninsulin dependent), and patients with T90 visited facilities in other towns more than those with K86 and T93. Patients with diseases of the eye, such as F91 (refractive error), F92 (cataract), and F71 (allergic conjunctivitis), and those with psychological disorders, such as P76 (depressive disorder), tended to visit facilities outside their towns rather than in their own towns.
Conclusions: Data regarding patients who visit medical facilities in their own towns may provide information on the role of primary care in that particular town. The analysis of medical reimbursement receipts from a particular area provides useful information about disease distribution in addition to an overview of the healthcare needs of the entire community in that area.

This is the third symposium on 'cancer and acupuncture and moxibustion'. Many physicians and intellectuals are skeptical of the use of Western medicine for cancer patients, which often lead to serious adverse events. Acupuncture and moxibustion, which is capable of improving quality of life (QOL) and activating immunity with minimal side effects is also expected to have beneficial effects on various stages of cancer patients, such as prevention of development or recurrence of cancer and palliative care. In fact, evidence has recently accumulated in the field. Dr. Fukuda, Associate Professor of Meiji University of Integrative Medicine, who reported the usefulness of acupuncture and moxibustion in palliative care in the first symposium and bibliographical information in the second has reported this time on the topic of safety and effectiveness of acupuncture on chemotherapy-induced peripheral neuropathy. Dr. Kurokawa from the National Defense Medical College reported the effectiveness of acupuncture on physical and psychological symptoms, QOL, prevention of adverse events, and pre-and post-operative disorders in cancer patients. Dr. Kouchi from Saitama Medical School reported on the usefulness of acupuncture in the university hospital and factors which influence the effect. Dr. Nakamura from Morinomiya University presented a case with chemotherapy-related symptoms who had been cared for with a long-term application of moxibustion. In contrast to these reports on the efficacy of the acupuncture for chemotherapy-and radiotherapy-induced side effects, Dr. Magara from Somon Hachipuji Clinic, who had consistently reported a preventive effect of autonomic immune therapy that involves acupuncture without Western clinical treatment from the first symposium, this time presented topics regarding improvement in the immunity by increasing various cytokines, the possibility of reduction of a tumor even in a case of advanced cancer that cannot be treated with a surgical approach, reduction of the recurrence rate among cases who were treated with his approach as compared with those under conventional approaches. He insisted we should concentrate our efforts on research on preventing the recurrence of cancer with approaches that activates the natural healing process of human beings.
We concluded that clinical trials with a larger sample are needed to clearly identify the usefulness of acupuncture and moxibustion for cancer patients.

Methods:
For this prospective multicenter study, 40 patients were followed up through radiologic and clinical examinations for at least 1 year postoperatively. All surgical procedures were either single- or double-level LLIF using bioactive porous titanium spacers without bone grafts.
Results:
Four patients were excluded from the study owing to aggravation from other comorbidities. Another 36 patients, including 26 and 10 with single- and double-level LLIFs, respectively, participated in the follow-up. The mean age at the time of surgery was 63.7 years. The mean operating time was 50.5 minutes per level. The mean estimated intraoperative blood loss was 11.6 mL per level. Clinical scores improved in all cases and were maintained throughout the follow-up period. The intervertebral bony union rates were 67.4% and 84.8% at 6 and 12 months, respectively. Endplate cyst signs were observed in 13.0% and 8.7% of patients at 6 and 12 months, respectively. Fused segmental angles were maintained throughout the follow-up period, indicating no cage subsidence.
Conclusions
Single- and double-level LLIFs using bioactive porous titanium spacers without bone grafts were found to be minimally invasive, resulting in clinical and imaging results comparable with conventional procedures. Therefore, this type of implant may be an option for minimally invasive spinal fusion surgery.

AIMTo report two cases of the left testicular artery arching over the left renal vein (LRV) before running downward to the testis.
METHODSThe subjects were obtained from two Japanese cadavers. During the student course of gross-anatomical dissection, the anatomical relationship between the testicular vessels and the renal vein was specifically observed.
RESULTSThe arching left testicular artery arose from the aorta below the LRV and made a loop around the LRV, which appeared to be mildly compressed between the arching artery and the psoas major muscle.
CONCLUSIONClinically, compression of the LRV between the abdominal aorta and the superior mesenteric artery occasionally induces LRV hypertension, resulting in varicocele, orthostatic proteinuria and hematuria. Considering that the incidence of a left arching testicular artery is higher than that of a right one, an arching left artery could be an additional cause of LRV hypertension.

Objective:
Breast cancer susceptibility gene 1 (BRCA1)-associated ovarian cancer patients have been treated with A poly (ADP-ribose) polymerase (PARP) inhibitor, extending the progression-free survival; however, they finally acquire therapeutic resistance. Interleukin (IL)-34 has been reported as a poor prognostic factor in several cancers, including ovarian cancer, and it contributes to the therapeutic resistance of chemotherapies. IL-34 may affect the therapeutic effect of PARP inhibitor through the regulation of tumor microenvironment (TME).
Methods:
In this study, The Cancer Genome Atlas (TCGA) data set was used to evaluate the prognosis of IL-34 and human ovarian serous carcinoma. We also used CRISPR-Cas9 genome editing technology in a mouse model to evaluate the efficacy of PARP inhibitor therapy in the presence or absence of IL-34.
Results:
We found that IL34 was an independent poor prognostic factor in ovarian serous carcinoma, and its high expression significantly shortens overall survival. Furthermore, in BRCA1-associated ovarian cancer, PARP inhibitor therapy contributes to anti-tumor immunity via the XCR1+ DC-CD8+ T cell axis, however, it is canceled by the presence of IL-34.
Conclusion
These results suggest that tumor-derived IL-34 benefits tumors by creating an immunosuppressive TME and conferring PARP inhibitor therapeutic resistance. Thus, we showed the pathological effect of IL-34 and the need for it as a therapeutic target in ovarian cancer.

BACKGROUND:
It has been pointed out that prolonged television (TV) viewing is one of the sedentary behaviors that is harmful to health; however, the association between socioeconomic status (SES) and prolonged TV viewing time has not been sufficiently investigated in Japan.
METHODS:
The study population are the participants of NIPPON DATA2010, which is a prospective cohort study of the National Health and Nutrition Survey 2010 in Japan. They were residents in 300 randomly selected areas across Japan. This study included 2752 adults. SES was classified according to the employment status, educational attainment, living status, and equivalent household expenditure (EHE). Prolonged TV viewing time was defined as more than or equal to 4 h of TV viewing per day. Multivariable logistic regression analyses were conducted to examine the association of SES with prolonged TV viewing time.
RESULTS:
The mean TV viewing time was 2.92 h in all participants. Of 2752 participants, 809 (29.4%) prolonged TV viewing, and the mean TV viewing time of them was 5.61 h. The mean TV viewing time in participants without prolonged TV viewing time was 1.81 h. The mean TV viewing time was prolonged as age classes increased and significantly longer in aged ≥60 years. Prolonged TV viewing time was associated with not working for all age classes and sexes. Only among women, education attainment and living status were also associated with prolonged TV viewing time. For education attainment, the lower the received years of education, the higher odds ratios (OR) of prolonged TV viewing time. For living status, in women aged <60 years, living with others had a significantly higher OR compared to living with spouse. On the other hand, in women aged ≥60 years, living alone had a significantly higher OR. EHE did not have any significant associations with prolonged TV viewing time.
CONCLUSIONS
In a general Japanese population, it should be noted that the association between SES and prolonged TV viewing time differed by age and sex. Particularly, it must draw attention to the prolonged TV viewing in elderly. The intervention in order to shorten TV viewing time needs to consider these attributes.

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.

BACKGROUND:
Oral health is thought to be associated with diet quality, and socioeconomic status (SES) affects both oral health and diet. The aim of this study was to investigate the association between the number of teeth and dietary intake as well as nutritional biomarker, considering the subjects' SES.
METHODS:
We conducted a cross-sectional analysis of data from 2049 individuals aged ≥ 50 years from the National Integrated Project for Prospective Observation of Non-communicable Disease and its Trends in the Aged 2010. The number of remaining teeth was categorized into age-specific quartiles (Q1 to Q4). We assessed the adjusted means and 95% confidence intervals for dietary variables by the number of teeth using analysis of covariance. Stratified analyses by SES were also conducted.
RESULTS:
The intake of grain products was 31 g higher, and those of vegetables and meat were 30 g and 8 g lower, respectively, in Q1 (fewer teeth) than in Q4 (more teeth). Carbohydrate intake was higher whereas protein, minerals (potassium, magnesium, and zinc), vitamins (vitamins A, E, B, B, β-carotene, and folic acid), and dietary fiber intakes were lower among individuals with fewer teeth. Adjusted mean serum albumin levels were low in Q1. The associations between the number of teeth and dietary intake were more evident in individuals with a low SES.
CONCLUSIONS
Having few remaining teeth was associated with a low nutrient intake and low serum albumin levels in middle-aged and older Japanese adults, and these associations were more evident in individuals with low SES.
