    Introduction: This study aimed to validate whether preoperative sarcopenia can predict long-term outcomes in patients with hepatocellular carcinoma (HCC) and identify the associations between sarcopenia and polyunsaturated fatty acids (PUFAs).

    Methods: This large, retrospective study included 353 patients who underwent hepatic resection for HCC and preoperative computed tomography scans. Skeletal muscle mass was measured at the third lumbar vertebrae. The cutoff value for sarcopenia followed the Japan Society of Hepatology's assessment criteria for sarcopenia.

    Results: Ninety-three patients (26.3%) with preoperative sarcopenia were enrolled. These patients had a significantly lower body mass index (p < 0.0001) and serum albumin level (p = 0.0070) as well as a higher rate of advanced-stage cancer (p = 0.0062) than those without sarcopenia. Patients with sarcopenia had significantly shorter overall survival than the other patients before (p = 0.0001) and after (p = 0.0415) propensity score matching. The sarcopenia group was significantly associated with low levels of eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA), which were categorized based on omega-3 PUFAs, compared with those in the non-sarcopenia group (p = 0.0030 and p = 0.0135).

    Conclusions: We demonstrated an association between sarcopenia and the long-term prognosis in patients with HCC. Low EPA and DHA levels were associated with preoperative sarcopenia. Further prospective studies are needed to investigate whether nutritional support using omega-3 PUFAs can prevent and manage skeletal muscle mass depletion.

    Introduction: Pharmacogenomic (PGx) testing results provide valuable information on drug selection and appropriate dosing, maximization of efficacy, and minimization of adverse effects. Although the number of large-scale, next-generation-sequencing-based PGx studies has recently increased, little is known about the risks and benefits of returning PGx results to ostensibly healthy individuals in research settings.

    Methods: Single-nucleotide variants of three actionable PGx genes, namely, MT-RNR1, CYP2C19, and NUDT15, were returned to 161 participants in a population-based Tohoku Medical Megabank project. Informed consent was obtained from the participants after a seminar on the outline of this study. The results were sent by mail alongside sealed information letter intended for clinicians. As an exception, genetic counseling was performed for the MT-RNR1 m.1555A > G variant carriers by a medical geneticist, and consultation with an otolaryngologist was encouraged. Questionnaire surveys (QSs) were conducted five times to evaluate the participants' understanding of the topic, psychological impact, and attitude toward the study.

    Results: Whereas the majority of participants were unfamiliar with the term PGx, and none had undergone PGx testing before the study, more than 80% of the participants felt that they could acquire basic PGx knowledge sufficient to understand their genomic results and were satisfied with their potential benefit and use in future prescriptions. On the other hand, some felt that the PGx concepts or terminology was difficult to fully understand and suggested that in-person return of the results was desirable.

    Conclusions: These results collectively suggest possible benefits of returning preemptive PGx information to ostensibly healthy cohort participants in a research setting.

    Introduction: Noncommunicable diseases (NCDs) are an ongoing public health problem globally. The present study aimed to estimate the prevalence of NCDs in Japan using a newly developed, commercially available administrative claims database covering young, middle-aged, and elderly people.

    Methods: We compared the age-stratified population distribution between the DeSC administrative claims database and the population estimates. We calculated the 1 year prevalence of several NCDs using the DeSC database and compared the prevalence of diabetes mellitus and hypertension between the DeSC database and the Japan National Health and Nutrition Survey.

    Results: The age distribution of the population included in the DeSC database was similar to that of the population estimates. The estimated prevalence rates were as follows: diabetes mellitus (12.2%), hypertension (20.9%), ischemic heart disease (5.6%), heart failure (5.3%), cerebral infarction (3.4%), stroke (3.7%), gastric cancer (0.6%), colorectal cancer (0.8%), breast cancer (1.5%), prostate cancer (0.6%), cataract (7.1%), depression (3.5%), and osteoporosis (6.3%). The estimated prevalence of diabetes and hypertension was comparable with that of the National Health and Nutrition Survey.

    Conclusions: The distribution of age and sex in the database was comparable with that of the population estimates. The prevalence of diabetes mellitus and hypertension was comparable with that in a previously reported national survey. Our data can be utilized as basic information for policymaking in clinical medicine and public health in Japan.

    Introduction: Participation in specific health checkups is low in Japan, especially among middle-aged community residents with municipal National Health Insurance (NHI). This study explored associations between recommendations from public health nurses, medical professionals, and family members and participation in specific health checkups among middle-aged Japanese community residents with NHI.

    Methods: This mail survey was conducted in 2020, and it included 33,902 community residents with NHI aged 40-64 years from five cities in Osaka Prefecture, Japan. Of these, 12,446 (36.7%) community residents agreed to participate in the survey. After excluding those with missing data, 11,180 participants were included in the analyses. Participants were classified into a participation group and a nonparticipation group. Those who selected "I underwent a specific health checkup in the past year" were classified as the participation group.

    Results: Of the 11,180 community residents with NHI, 4,384 (39.2%) were classified in the participation group. After adjusting for confounding factors, the presence (vs. absence) of recommendations from public health nurses (multivariable-adjusted odds ratio [OR], 1.81; 95% confidence interval [CI], 1.47-2.24), primary care physicians (multivariable-adjusted OR, 2.79; 95% CI, 2.49-3.13), nurses (multivariable-adjusted OR, 2.06; 95% CI, 1.57-2.69), and family members (multivariable-adjusted OR, 1.22; 95% CI, 1.12-1.32) was positively associated with participation in specific health checkups.

    Conclusions: Our findings suggest that recommendations from public health nurses, medical professionals (primary care physicians and nurses), and family members may be important to promote participation in specific health checkups among middle-aged Japanese community residents with NHI.

    Introduction: Bowel obstruction at the outlet of the stoma, also referred to as "stoma outlet obstruction" (SOO), has been noted to be more common after laparoscopic colorectal surgery with diverting ileostomy than after laparotomy. Thus, the aim of this study is to identify the risk factors for SOO and to evaluate the effectiveness of a modified ileostomy procedure for reducing its incidence.

    Methods: The medical records of 63 patients who underwent laparoscopic colorectal surgery with diverting ileostomy between January 2014 and July 2021 were retrospectively reviewed. We analyzed the risk factors for SOO using computed tomography findings.

    Results: In total, 34 patients underwent surgery before modification of the ileostomy procedure (LSa group), and 29 patients underwent surgery after modification (LSb group). In the LSa group, 6 patients have reportedly developed SOO (SOO group), whereas 28 patients did not (non-SOO group). No patients in the LSb group developed SOO. The thickness of the abdominal rectus muscle (ThM) in the SOO group and the non-SOO group was 13.4 mm and 9.6 mm, respectively (p = 0.005). The angle between the ileostomy and the abdominal wall (AIW) was 95.8° in the non-SOO group and 82.2° in the SOO group (p = 0.033). The AIW was 93.4° in the LSa group and 99.7° in the LSb group (p = 0.043).

    Conclusions: As per our findings, a thick abdominal rectus muscle is predictive of SOO. Correction of the AIW (eliminating medial inclination) by modifying the operative technique has eliminated the occurrence of SOO in our patient population.

    Introduction: Overt hyperthyroidism and hypothyroidism are associated with pregnancy complications; however, most women with these conditions are diagnosed before conception and are under treatment during pregnancy, especially in high-income countries. The purpose of this study was to investigate pregnancy complications among these women.

    Methods: A retrospective cohort study was conducted, and data on pregnant women who gave birth to a singleton at Nagoya University Hospital in Japan in 2005-2014 was collected. The pregnancy outcomes were divided and compared among three groups: the control group (n = 3531), the hyperthyroidism group (n = 48), and the hypothyroidism group (n = 61). Additionally, risk factors for placental abruption were evaluated by multivariable logistic regression analysis. Moreover, in hyperthyroidism, thyroid function at the placentation period was compared between placental-related diseases and nonplacental-related disease groups, and the latter group included placental abruption and preeclampsia.

    Results: The incidence of placental abruption was higher in hyperthyroidism than in control and hypothyroidism groups. Hyperthyroidism was independently associated with an increased risk of placental abruption (adjusted odds ratio, aOR = 8.21, 95% confidence interval, CI: 1.76-38.34), as well as preeclampsia (aOR = 4.10, 95% CI: 1.13-14.76) and preterm labor (aOR = 3.38, 95% CI: 1.19-9.64). Additionally, thyroid-stimulating hormone (TSH) at the placentation period was significantly lower in the placental-related disease group than in the nonplacental-related disease group (p < 0.05).

    Conclusions: Pregnancy outcomes in women with hyperthyroidism and hypothyroidism would be comparable with those without thyroid disease. Hyperthyroidism was an independent risk factor for placental abruption as well as preterm labor and preeclampsia. However, its frequency was extremely low, and further research is required to validate our findings.

    Introduction: The Halabi model predicts the overall survival (OS) of patients with metastatic castration-resistant prostate cancer (mCRPC) treated with second-line therapy after docetaxel. We aimed to validate this model externally with an independent cohort, outside the setting of a clinical trial.

    Methods: In a multi-institutional study, we included 66 patients treated with cabazitaxel after docetaxel for mCRPC. Patients were stratified according to the two- and three-risk groups of the Halabi nomogram. Kaplan-Meier and Cox proportional hazard analyses were performed to estimate survival and hazard ratios (HRs). The model performance was assessed using receiver operating characteristic curves, and the associated c-index (area under the curve [AUC]).

    Results: The median OS in the two-risk groups was 5.06 months in the high-risk group (n=22) and 12.9 months in the low-risk group (n=44, p<0.001). High-risk patients had an HR of 9.50 (95% confidence interval (CI) 4.12-21.6, p<0.001) compared to low-risk patients. For the three-risk groups, the median OS was 6.44 months in the high-risk group (n=15), 5.75 months in the intermediate-risk group (n=11), and 13.7 months in the low-risk group (n=40, p=0.84). Compared to low-risk patients, intermediate-risk patients had an HR of 7.49 (95% CI 3.08-20.4, p<0.001), and high-risk patients had an HR of 8.48 (95% CI, 3.39-21.7, p<0.001). The AUC was 0.72 (95% CI 0.64-0.76) for the two-risk stratification. When comparing different risks, the AUCs were 0.48 (high vs intermediate), 0.66 (high vs low), and 0.65 (intermediate vs low).

    Conclusions: The two-risk stratification version but not the three-risk group analysis confirmed the ability of the model to predict survival. These results support the value of the Halabi nomogram in men receiving post-docetaxel second-line chemotherapy for mCRPC.

    Introduction: The use of a simple diagnostic system for nonalcoholic fatty liver disease (NAFLD) instead of a biopsy is expected. We investigated a positive pattern recognition system for the evaluation of nonalcoholic fatty liver (NAFL) and the stages of nonalcoholic steatohepatitis (NASH).

    Methods: A total of 68 Japanese patients with biopsy-confirmed NAFLD were enrolled. Serological biomarkers and medical imaging markers were investigated to determine candidate markers. The markers were statistically evaluated, and the patients were distributed to pattern combinations.

    Results: We selected three markers based on natural history and set the critical values: alanine aminotransferase/ALT (persistent ≥ 44 IU/L) as a marker for hepatitis, type IV collagen 7S (≥5.1 ng/mL) for fibrosis, and E value (≥5.5 kPa) for stiffness. After evaluation of statistical accuracies, every patient was classified into their combination patterns. Comparing the relationships between histological classifications and positive patterns, the patients with NAFL were mainly distributed in pattern (ALT, type IV collagen, E value: −, −, −), those with NASH stage 0-1 in (+, −, +), those with NASH stage 2-3 in (+, +, +), and those with NASH stage 4 in (−, +, +).

    Conclusions: The positive patters changed with the NAFL and NASH conditions. Our results indicated a correlation between the positive patterns using three markers and the histological results. The positive pattern recognition system based on natural history is useful for the differential diagnosis of NAFLD and for the evaluation of the severity of fibrosis in patients with NASH.

    Several patients undergoing physical therapy have nutritional problems. Knowledge of nutrition is necessary for addressing nutritional problems, such as malnutrition, sarcopenia, frailty, and cachexia. However, the relationship between physical therapy and nutrition is not fully understood. Physical therapy plays an important role in nutritional management, and evaluations, such as muscle strength and muscle mass evaluations, play an important role in nutritional screening and diagnosis. Exercise, as the core of physical therapy, is essential for nutritional interventions. Several recent studies have suggested that a combination of nutrition and physical therapy interventions can maximize the function, activity, participation, and quality of life of patients. The combination of nutrition and physical therapy interventions is key to addressing the needs of modern and diverse populations. This position paper was developed by the Physical Therapist Section of the Japanese Association of Rehabilitation Nutrition in consultation with the Japanese Society of Nutrition and Swallowing Physical Therapy.

    Nutritional disorders diminish the effectiveness of physical therapy. The pathogenesis of nutritional disorders, such as sarcopenia, frailty, and cachexia, differs from disease to disease. Disease-specific nutrition can maximize the function, activity, participation, and quality of life for patients undergoing physical therapy, a practice known as nutritional physical therapy. Understanding and practicing disease-specific nutritional physical therapy is essential to meet patients' diverse needs and goals with any disease. Thus, the physical therapist division of the Japanese Association of Rehabilitation Nutrition, with advice from the Japanese Society of Nutrition and Swallowing Physical Therapy, developed this review. It discusses the impact of disease-specific nutritional physical therapy on sarcopenia and frailty in community-dwelling older adults, obesity and metabolic syndrome, critical illness, musculoskeletal diseases, stroke, respiratory diseases, cardiovascular diseases, diabetes, renal disease, cancer, and sports.

    IgA vasculitis is the most common systemic small vasculitis in children. Its major clinical manifestations are palpable purpura, arthritis and arthralgias, gastrointestinal involvement, and renal manifestations. Regarding gastrointestinal manifestations, steroids are effective in reducing abdominal pain. However, exacerbation of gastrointestinal manifestation is frequently experienced when the steroid dose is being tapered. Thus, reliable biomarkers for gastrointestinal mucosal inflammation are needed. We report the case of a 4-year-old girl with abdominal-type IgA vasculitis. During the clinical course, we used several markers, such as fecal immunochemical test, fecal α1-antitrypsin and calprotectin. When fecal immunochemical test showed negative results and fecal α1-antitrypsin value returned to the normal range, corresponding to her abdominal pain improvement, fecal calprotectin levels remained high. This suggests that fecal calprotectin is more sensitive for evaluating mucosal inflammation than other markers. It could be a useful marker for mucosal inflammation in IgA vasculitis.
