Relationship between abdominal circumference and the incidence of hyperuricemia in the general Japanese population.

In this study, we aimed to separately evaluate the relationship between waist circumference and the incidence of hyperuricemia in men and women in the general Japanese population. We performed a population-based longitudinal study using data from the annual health examination of residents of Iki City, Japan. A total of 5567 participants without hyperuricemia at baseline were included in the analysis. The men and women were placed into groups according to the tertile of waist circumference. The outcome was incident hyperuricemia (uric acid > 416 µmol/L [7.0 mg/dL]). The relationship between waist circumference and the incidence of hyperuricemia was investigated using Cox proportional hazards models. During the follow-up period, hyperuricemia developed in 697 people (551 men and 146 women). The incidence (per 1000 person-years) of hyperuricemia increased with increasing waist circumference in the men (34.9 for tertile 1, 49.9 for tertile 2 and 63.3 for tertile 3; Ptrend < 0.001) and women (5.5 for tertile 1, 6.3 for tertile 2 and 11.9 for tertile 3; Ptrend < 0.001). Significant associations were identified after adjustment for potential confounders (men: Ptrend < 0.001; women: Ptrend = 0.014). In conclusion, both men and women with larger waist circumferences were at higher risks of subsequent hyperuricemia.

Two-year evolution of quality of life following radiotherapy and/or chemotherapy in patients with head and neck cancer.

Objective: This study aims to elucidate the trajectory of quality of life (QoL) over a two-year period after radiotherapy and/or chemotherapy for head and neck cancer (HNC), addressing the gap in long-term QoL information. Methods: Employing a prospective longitudinal observational design, we tracked 58 HNC patients who underwent radiotherapy and/or chemotherapy, analyzing their QoL using Short-Form 36-Item Health Survey version 2 (SF36v2), the European Organization for Research and Treatment of Cancer quality of life (EORTC-QLQ-C30), and the European Organization for Research and Treatment of Cancer quality of life head and neck-35 (EORTC-QLQ-H&N35) questionnaires for two years post-discharge. The data underwent repeated measures analysis of variance. Results: Over the two-year follow-up, 10 patients (17.2%) succumbed, and 8 (13.8%) dropped out. SF36v2 physical and role-social component summary scores declined during treatment, requiring 1-2 years for recovery. The mental component summary score remained stable. EORTC-QLQ-30 revealed global health status recovery within one year post-discharge. EORTC-QLQ-H&N35 items like "swallowing," "senses problems," "trouble with social eating," "dry mouth," "sticky saliva," "coughing," and "felt ill" worsened pre-discharge. "Trouble with social contact" improved within a year, while "pain," "swallowing," "senses problems," "trouble with social eating," and "coughing" improved within two years. "Dry mouth" and "sticky saliva" persisted throughout the two-year follow-up, common symptoms of HNC and treatment side effects. Conclusions: Recovery of specific QoL aspects in HNC patients treated with radiotherapy and/or chemotherapy may require up to two years. Prolonged monitoring and management of oral symptoms could enhance QoL. Future research should extend follow-up beyond two years for comprehensive interventions enhancing patient QoL.

Association between serum ALT levels and incidence of new-onset diabetes in general population of Japanese: a longitudinal observational study (ISSA-CKD).

OBJECTIVE: We aimed to clarify the relationship between serum alanine transaminase (ALT) levels and incidence of new-onset diabetes in a Japanese general population. SETTING: Population-based retrospective cohort study using annual health check-up data for residents of Iki City, Nagasaki Prefecture, Japan. PARTICIPANTS: A total of 5330 Japanese individuals (≥30 years old) without diabetes at baseline were analysed. PRIMARY AND SECONDARY OUTCOME MEASURES: Serum ALT levels were determined using an enzymatic method and were classified into gender-specific quartile groups as follows: group 1 (3-16 U/L in men and 3-13 U/L in women), group 2 (17-21 U/L in men and 14-16 U/L in women), group 3 (22-29 U/L in men and 17-22 U/L in women) and group 4 (30-428 U/L in men and 23-268 U/L in women). The study outcome was the incidence of diabetes (fasting glucose ≥7.0 mmol/L, non-fasting glucose ≥11.1 mmol/L, glycated haemoglobin ≥6.5% or use of glucose-lowering therapies). RESULTS: After an average follow-up period of 5.0 years, 279 individuals developed diabetes. The incidence rate of diabetes increased with elevation of serum ALT levels (0.7% per 100 person-years in group 1, 0.9% in group 2, 0.9% in group 3 and 1.7% in group 4) (p<0.001 for trend). This association was significant after adjustment for other risk factors including age, sex, obesity, hypertension, dyslipidaemia, smoking, current daily alcohol intake and regular exercise (p<0.001 for trend). Comparable associations were observed between men and women (p=0.459 for interaction). CONCLUSION: Serum ALT levels were associated with future development of diabetes in the general Japanese population.

Association between pulse pressure and progression of chronic kidney disease.

The aim of this study was to investigate the association between pulse pressure (PP) and chronic kidney disease (CKD) progression among the general population in Japan. We conducted a population-based cohort study of the residents of Iki Island, Nagasaki, Japan, from 2008 to 2018. We identified 1042 participants who had CKD (estimated glomerular filtration rate(eGFR) < 60 mL/min/1.73 m2 or the presence of proteinuria) at baseline. Cox's proportional hazard model was used to evaluate the association between PP and progression of CKD. During a 4.66-year mean follow-up, there were 241 cases of CKD progression (incident rate: 49.8 per 1000 person-years). A significant increase existed in CKD progression per 10 mmHg of PP elevation, even when adjusted for confounding factors [adjusted hazard ratio 1.17 (1.06-1.29) p < 0.001]. Similar results were obtained even after dividing PP into quartiles [Q2: 1.14 (0.74-1.76), Q3: 1.35 (0.88-2.06), Q4: 1.87 (1.23-2.83) p = 0.003 for trend]. This trend did not change significantly irrespective of baseline systolic or diastolic blood pressures. PP remained a potential predictive marker, especially for eGFR decline. In conclusion, we found a significant association between PP and CKD progression. PP might be a potential predictive marker for CKD progression.

Effects of occupational status on social adjustment after laryngectomy in patients with laryngeal and hypopharyngeal cancer.

PURPOSE: This study was performed to examine the relationship of social adjustment with occupation and life changes in patients with laryngeal and hypopharyngeal cancer, from before laryngectomy to 1 year after hospital discharge. METHODS: The subjects were 27 patients with laryngeal and hypopharyngeal cancer who were admitted to hospital for laryngectomy and provided informed consent for participation in the study. The patients answered questionnaire surveys before surgery, and 3, 6, and 12 months after hospital discharge. Regarding social adjustment, social functioning (SF) and mental health (MH) in SF-36V2 were used as dependent variables, and time, occupation status, age, family structure, and sex as independent variables. Repeated measures analysis of variance was used to examine the main effect, and second- and third-order interactions were also examined. RESULTS: The age of the subjects was 62.9 ± 6.4 years and about 30% had an occupation. Loss of voice was the reason for 30% leaving work. In an examination of the main effects of the four variables, only age was significant regarding SF, and SF was favorable in subjects aged ≥ 64 years old. Regarding MH, age and family structure were significant, and MH was higher in older subjects who lived alone. The interaction between time and the other 3 variables was not significant. Only time/age/occupation was significant for MH. Regarding SF, a weak interaction was suggested, but it was not significant. CONCLUSION: Older subjects showed better social adjustment, and those who lived alone had better MH. These findings may have been due to a reduced environmental influence. MH of subjects with an occupation decreased more at 3 months or later after hospital discharge, compared to those without an occupation. Especially for younger patients, development of new approaches is required to allow families and colleagues of patients to understand the difficulties of patients with laryngeal and hypopharyngeal cancer.

Social support and substitute voice acquisition on psychological adjustment among patients after laryngectomy.

The objective is to clarify whether social support and acquisition of alternative voice enhance the psychological adjustment of laryngectomized patients and which part of the psychological adjustment structure would be influenced by social support. We contacted 1445 patients enrolled in a patient association using mail surveys and 679 patients agreed to participate in the study. The survey items included age, sex, occupation, post-surgery duration, communication method, psychological adjustment (by the Nottingham Adjustment Scale Japanese Laryngectomy Version: NAS-J-L), and the formal support (by Hospital Patient Satisfaction Questionnaire-25: HPSQ-25). Social support and communication methods were added to the three-tier structural model of psychological adjustment shown in our previous study, and a covariance structure analysis was conducted. Formal/informal supports and acquisition of alternative voice influence only the "recognition of oneself as voluntary agent", the first tier of the three-tier structure of psychological adjustment. The results suggest that social support and acquisition of alternative voice may enhance the recognition of oneself as voluntary agent and promote the psychological adjustment.
