Lower Masticatory Performance Is a Risk for the Development of the Metabolic Syndrome: The Suita Study

Objectives: Declined masticatory function has recently been receiving attention as a risk factor for poor general health. The present longitudinal analysis was conducted to clarify the relationship between decreased masticatory performance and the development of the metabolic syndrome (MetS) in a general urban cohort in Japan.Methods: We surveyed 599 participants (254 men, 345 women; mean age at baseline, 65.8 ± 7.8 years) who underwent physical health checkups in the Suita study. We evaluated masticatory performance at baseline using test gummy jelly and divided participants into two groups: a “Lower group,” comprising participants in the lower 25% of the masticatory performance at baseline; and a “Normal group,” comprising all others. We estimated hazard ratios (HRs) for the Lower group by using Cox proportional hazard regression analysis to develop the MetS and the components of the MetS at follow-up, adjusting for age, smoking status, and periodontal status.Results: On Cox proportional hazard regression analysis, the multivariable adjusted hazard ratio for the development of the MetS in the Lower group was 2.24 (95% confidence interval, 1.12–4.50) in men. The multivariable adjusted hazard ratio for the development of high blood pressure was 3.12 (1.42–6.87), for high triglycerides was 2.82 (1.18–6.76), and for high fasting plasma glucose was 2.65 (1.00–7.00) in men.Conclusions: Lower masticatory performance suggested to be a risk factor for the development of the MetS as well as MetS components such as high blood pressure, high triglycerides, and high fasting plasma glucose in Japanese men.

Abstract Background Serum parathyroid hormone (PTH) levels have been reported to be associated with infectious mortality in peritoneal dialysis (PD) patients. Peritonitis is the most common and fatal infectious complication, resulting in technique failure, hospital admission and mortality. Whether PTH is associated with peritonitis episodes remains unclear. Methods We examined the association of PTH levels and peritonitis incidence in a 7-year cohort of 270 incident PD patients who were maintained on dialysis between January 2012 and December 2018 using Cox proportional hazard regression analyses. Patients were categorized into three groups by serum PTH levels as follows: low-PTH group, PTH < 150 pg/mL; middle-PTH group, PTH 150-300 pg/mL; high-PTH group, PTH > 300 pg/mL. Results During a median follow-up of 29.5 (interquartile range 16–49) months, the incidence rate of peritonitis was 0.10 episodes per patient-year. Gram-positive organisms were the most common causative microorganisms (36.2%), and higher percentage of Gram-negative organisms was noted in patients with low PTH levels. Low PTH levels were associated with older age, higher eGFR, higher hemoglobin, calcium levels and lower phosphate, alkaline phosphatase levels. After multivariate adjustment, lower PTH levels were identified as an independent risk factor for peritonitis episodes [hazard ratio 1.643, 95% confidence interval 1.014–2.663, P = 0.044]. Conclusions Low PTH levels are independently associated with peritonitis in incident PD patients.

The Metabolic Syndrome

Background: The prevalence of obesity, one risk factor for developing the metabolic syndrome (MS), has increased during the last decades. It has therefore been assumed that the prevalence of MS would also increase. Aims: The aim was to analyse the prevalence of MS and its risk factors in a middle-aged Swedish population. Methods: Data were obtained between 2003 and 2004 from a random population based sample of 502 men and 505 women, 45–69 years old. Measures of plasma glucose, serum lipids, blood pressure, weight, height, waist circumference and self-reported data concerning presence of disease, medication and lifestyle were obtained. Results: The prevalence of MS was 14.8% among men and 15.3% among women, with an increase by age among women only, 10% to 25% ( p = 0.029). Among individuals with MS the most frequent risk factor was large waist circumference, present in 85% of men and 99% of women, followed by high blood pressure, high triglycerides, high glucose and HDL cholesterol (38% and 47% respectively). Conclusion: The prevalence of MS was 15%, increasing with age only among women. Overweight was a dominant characteristic, and only half of the individuals with MS had glucose/HDL cholesterol levels beyond defined cut points of the syndrome.

Abstract Post–polycythemia vera myelofibrosis (post-PV MF) is a late evolution of PV. In 647 patients with PV, we found that leukocytosis leukocyte count > (15 × 109/L) at diagnosis is a risk factor for the evolution of post-PV MF. In a series of 68 patients who developed post-PV MF, median survival was 5.7 years. Hemoglobin level less than 100 g/L (10 g/dL) at diagnosis of post-PV MF was an independent risk factor for survival. The course of post-PV MF, however, is a dynamic process that implies a progressive worsening of clinical parameters. Using a multivariate Cox proportional hazard regression with time-dependent covariates, we found that a dynamic score based on hemoglobin level less than 100 g/L (10 g/dL), platelet count less than 100 × 109/L, and leukocyte count more than 30 × 109/L is useful to predict survival at any time from diagnosis of post-PV MF. The resulting hazard ratio of the score was 4.2 (95% CI: 2.4-7.7; P < .001), meaning a 4.2-fold worsening of survival for each risk factor acquired during follow up. In conclusion, leukocytosis at diagnosis of PV is a risk factor for evolution in post-PV MF. A dynamic score based on hemoglobin level, and platelet and leukocyte count predicts survival at any time from diagnosis of post-PV MF.

Our objective was to search for differences in genotypes of peroxisome proliferator-activated receptor gamma (PPARγ) (Pro12 Ala) and its coactivator PGC-1α (Gly482 Ser) in adolescents harboring features of metabolic syndrome. In a population-based study, we determined medical history, anthropometric variables, biochemical measurements and arterial blood pressures of 934 high-school students of Caucasian origin. We selected 220 adolescents who had systolic or diastolic blood pressures more than the 80th or less than the 20th percentiles based on the previous single set of measurements. One hundred and seventy-five adolescents completed the study and underwent two additional blood pressure measurements on different days, as well as biochemical analysis and genotyping. We found no association between insulin resistance, body mass index (BMI) and leptin levels and PPARγ and PGC-1α genotypes. The 12 Ala PPARγ allele was associated with increased waist-to-hip ratio (WHR) and carriers seemed to have higher diastolic blood pressure and lower pulse pressure than non-carriers, particularly in the hypertensive and overweight group. Although Ser482 Ser PGC-1α homozygotes had lower WHRs than other PGC-1α genotypes, they were more frequent in the hypertensive group than in the normotensive (44.4 vs 24.5%, P<0.03), so the 482 Ser PGC-1 allele was in our population a risk factor for hypertension independently of WHR, homeostasis model assessment of insulin resistance, BMI and Pro12 Ala PPARγ variant (odds ratio=4.0, 95% confidence interval 1.5–10.6, P<0.01). Multiple regression analysis showed that age- and sex-adjusted systolic blood pressure correlated with the 482 Ser PGC-1 allele regardless of those covariates. In conclusion, the Gly482 Ser variant of the PGC-1α gene may be an independent genetic risk factor for young-onset hypertension.
