“…The HPA axis responses to stress have been found to differ between men and women (Kudielka and Kirschbaum, 2005). This finding along with the findings that differences between men and women in the nature of psychobehavioral responses to stress, as well as in their respective capacities to tolerate stress, may exist (Frankenhaeuser et al, 1978;Kessler andMcLeod, 1984, Yamamoto et al, 2007;Yamamoto et al, 2008) will explain the gender differences in the association of stress score with the biomedical parameters. Our findings suggest that psychosocial stress defined as the accumulation of somatic, psychological, and behavioral changes occurring as a result of exposure to psychosocial stress is associated with the metabolic syndrome, though its causal relationship remains unclear.…”

“…The subjects included in the present study were selected from a smaller pool of 1,941 workers examined at the hospital between November 2004 and March 2005. Details regarding the subject and procedure have been reported elsewhere (Yamamoto et al, 2007;Yamamoto et al, 2008). The subjects were invited to participate in the study after they had been provided with a full explanation of the study and written informed consent was obtained from all participants.…”

“…Previously, we developed an inventory to measure psychosocial stress (IMPS) that evaluates stress as the accumulation of somatic, psychological, and behavioral changes occurring in a person as a result of exposure to psychosocial stress. This inventory has been shown to be potentially capable of measuring psychosocial stress levels (Yamamoto et al, 2007;Yamamoto et al, 2008;Yamamoto et al, 2009). In an attempt to clarify the relationship between psychosocial stress, age, BMI, CRP, lifestyle factors, and the metabolic syndrome, a cross-sectional study was conducted among apparently healthy subjects.…”

The aim of this cross-sectional study was to examine the factors which may be associated with the metabolic syndrome by exploring the relationship between psychosocial stress, age, body mass index (BMI), C-reactive protein (CRP), lifestyle factors, and the components of the metabolic syndrome, such as glycated hemoglobin (HbA1c), fasting blood sugar (FBS), body fat percentage, and triglyceride concentration, among apparently healthy subjects. Psychosocial stress was measured by the use of the inventory to measure psychosocial stress (IMPS). One thousand four hundred and ninety-nine people out of 1,941 public school workers admitted to a hospital for a medical check-up responded to the IMPS, yielding a response rate of 77.2%. A total of 1,201 workers excluding 298 who were taking medication for various diseases were analyzed with the use of hierarchical multiple regression models. It was found that IMPS-measured stress score, age, BMI, and smoking habit were associated with an increase in glycated hemoglobin among men, while alcohol consumption was associated with a decrease in glycated hemoglobin. Stress score, age, BMI, and alcohol consumption were found to be associated with an increase in FBS among men, while smoking and exercise habits were associated with a decrease in FBS. CRP was found to be associated with an increase in body fat percentage among men, though stress score was not associated with an increase in body fat percentage. Stress score, age, and BMI were associated with an increase in triglyceride concentration among women. The findings of the present study seem to be in line with the hypothesis that psychosocial stress plays an important role in developing the metabolic syndrome, which may be associated with inflammatory processes in the vascular wall, resulting in atherosclerosis and cardiovascular disease.

“…[28] Distress associated with uncomfortable symptoms including irritation, pain, and dryness could also raise IOP, particularly because depression is prevalent in DED patients and worsens in winter, and thus this state might result in ocular hypertension. [29][30][31][32] Such an outcome might also explain the IOP reduction noted in summer when the corneal staining scores and DED symptoms are least severe. IOP and blood pressure are positively correlated and increased in winter, [13,14] and adrenergic receptor activation has been conventionally proposed as a possible regulatory system for this phenomenon.…”

Tel: +81-3-5363-3821 M.A. and K.N. equally contributed to this work. Abstract: Purpose: To evaluate seasonal variation in intra-ocular pressure (IOP) with and without short tear breakup time (SBUT, BUT ≤ 5 s).Methods: This study enrolled 176 patients who visited one of six eye clinics in Japan for IOP measurement at every season. The mean patient age was 67.9 years, including 79 males. We compared the seasonal variation in IOP (mean ± SD) across spring (Mar-May), summer (Jun-Aug), fall (Sep-Nov), and winter (Dec-Feb). Results:The IOP (mmHg) in winter and summer, respectively, was 12.8 ± 3.7 and 12.8 ± 3.1 for nonglaucoma patients without SBUT (n = 47, P = 0.964), 14.8 ± 3.4 and 13.3 ± 3.4 for non-glaucoma patients with SBUT (n = 57, P < 0.001), 14.3 ± 3.2 and 14.1 ± 3.4 for glaucoma patients without SBUT (n = 36, P = 0.489), and 13.3 ± 3.0 and 11.6 ± 2.9 for glaucoma with SBUT (n = 36, P < 0.001). Seasonal variation was largest across the seasons in the glaucoma with SBUT group, and the magnitude of seasonal variation correlated with BUT (β = 0.228, P = 0.003). Conclusions:Seasonal variation tended to be larger in patients with SBUT than those without SBUT.

Purpose To examine whether automated visual field (VF) testing may exert a short-term influence on subsequent intraocular pressure (IOP) measurement during the same visit. Methods We reviewed patients with primary open-angle glaucoma whose most recent visit occurred at a major academic institution from July to December 2009 and who had 3 visits without intervening changes in glaucoma management within the previous 5 years. Exclusion criteria were patient admittance of nonadherence with medical therapy and documented difficulty of IOP measurement. One hundred nine right eyes from 109 patients were included. IOP obtained within 30 minutes after VF testing was compared with IOP from the previous and next visits without VF testing. Subgroup analyses included the role of reliability of VF test performance, surgical versus medical IOP control, and different topical medications. Results The average IOP measured after VF testing was 14.9± 4.7 mm Hg, higher than both the previous (13.7±4.4 mm Hg, P<0.001) and next visits without VF examination (13.8±4.4 mm Hg, P<0.001). A total of 22.9% of patients experienced a more than 20% increase of IOP. Eyes with surgical control had less IOP elevation than eyes with medical control (3.1%±15.9% vs. 11.7%±17.4%, P=0.009). Users of β-blockers or α-2-agonists had less IOP elevation than eyes controlled with prostaglandins or carbonic anhydrase inhibitors (0.9%±15.1% vs. 9.0%±12.3%, P=0.030). Conclusions This retrospective study suggests that patients with primary open-angle glaucoma experience a small and transient increase in IOP after VF testing and that this effect may be lower after surgical pressure control.
