Objective: This study aims to examine the relationship between chronic prostatic inflammation and prostatic calculi, and clinical parameters of benign prostatic hyperplasia (BPH). Materials and Methods: This study was based on 225 patients who underwent transurethral resection of the prostate for BPH. Chronic inflammation was graded as 0 (n = 44), I (n = 54), II (n = 88) or III (n = 39) according to severity. Prostatic calculi were classified into types A (n = 66), B (n = 44), M (n = 77) and N (n = 38). The relationship between inflammation and calculus type was analyzed, and clinical parameters of BPH were compared for each group. Results: There was no correlation between severity of inflammation and calculus type. Prostatic volume increased with the severity of inflammation and showed significant differences between G2, G3 and G0. The International Prostate Symptom Score also increased with increasing inflammation. There was no significant difference between each clinical parameter according to calculus type. Conclusions: Prostatic calculi had no significant association with chronic inflamma- tion and clinical parameters of BPH. Chronic inflammation was associated with the volume of the prostate and storage symptoms; thus, it is not only presumed to be related to the progression of BPH, but may also be one of the causes of lower urinary tract symptoms.
Several lines of evidence from previous studies suggest that Calcium (Ca) and Magnesium (Mg) may be involved in intracellular and interneuronal processes associated with affective disorders. However, there have been inconsistent results on the effect of Ca and Mg on depressive mood disorder. This cross-sectional study was conducted to determine whether serum Ca and Mg levels, as well as serum Ca/Mg ratio, are associated with mental health in relatively healthy, adult women without psychiatric disorders. One hundred and twelve adult women were recruited from the outpatient clinic in a university hospital setting. Serum Ca and Mg levels were measured and indicators of mental health such as depression, anxiety, and stress were evaluated using two validated questionnaires; the Hospital Anxiety Depression Scale and the Modified Brief Encounter Psychosocial Instrument Stress Scale. After categorizing the serum Ca and Mg levels, and the Ca/Mg ratio into tertiles, the mean scores on each mental health scale were compared using analysis of covariance. The risk of depressive mood disorder according to the tertiles of serum Mg level and serum Ca/Mg ratio was assessed using logistic regression analysis. Women in the middle tertile of serum Ca/Mg ratio had significantly lower scores on depression and stress scales (p = 0.004 and p = 0.007, respectively) and a lower odds ratio (OR) for the risk of depressive mood disorder (OR = 0.31, CI(95%) 0.10-0.93) than those in the highest tertile. The OR for the risk of depressive mood disorder was higher in women in the lowest tertile of serum Mg than in those in the highest tertile (OR = 3.92, CI(95%) 1.11-13.83). Serum Mg level and serum Ca/Mg ratio may be involved in the mechanism for the progression of depressive mood or stress perception in relatively healthy, adult women.
The cerebellum is an important region responsible for adolescent cognitive function and sleep, and their correlation is expected to show different patterns depending on age and gender. We examined the regional cerebellar gray matter volume (GMV), executive function (EF) and insomnia symptoms to identify their correlation and gender differences in adolescents. Data for a total of 55 subjects’ (M = 31, F = 24, 14.80 ± 1.39 years old) were analyzed. The correlations between cerebellar regional GMV and Wisconsin card sorting test (WCST) subcategories showed that EF was better with larger GMV both in males and females. Far more overall correlations with cerebellar regions were observed in boys, with corresponding correlation strength being higher, and differences in localization were also observed in contrast to girls. Larger cerebellar GMV corresponded to better EF in adolescents. Insomnia did not influence the correlations between cerebellar regional GMV and EF, but more severe insomnia in boys correlated to smaller GMV in the right flocculonodular lobe. These results might implicate that the adolescent cerebellum is involved differently in EF dependent on gender.
AbstractsBackgroundAdolescence is a period of marked sleep pattern changes and sleep problems, which may result from both endogenous and exogenous factors. Among the various factors affecting adolescent sleep, depression and problematic Internet use (PIU) have received considerable attention. We examined if there is a different PIU effect on sleep between depressed group and non-depressed groups.MethodsData for a total of 766 students’ between 7th and 11th grades were analyzed. We assessed various variables related sleep to problems and depression and compared those variables between an adolescent group with problematic Internet use (PIUG) and an adolescent group with normal Internet use (NIUG).ResultsOne hundred fifty two participants were classified as PIUG, and 614 were classified as NIUG. Compared with the NIUG, the members of the PIUG were more prone to insomnia, excessive daytime sleepiness and sleep-wake behavior problems. The PIUG also tended to include more evening types than the NIUG. Interestingly, the effect of Internet use problems on sleep problems appeared to be different according to the presence or absence of the moderating effect of depression. When we considered the moderating effect of depression, the effect of Internet use problems on sleep-wake behavior problems, insomnia and excessive daytime sleepiness increased with increasing Young’s Internet Addiction Scale (IAS) scores in the non-depressed group. However, in the depressed group, the effects of Internet use problems on sleep-wake behavior problems and insomnia did not change with increasing Internet use problems, and the effect of Internet use problems on excessive daytime sleepiness was relatively decreased with increasing Internet use problems in the depressed group.ConclusionsThis study demonstrated that the effect of PIU on sleep presented differently between the depressed and non-depressed groups. PIU is associated with poorer sleep in non-depressed adolescents but not in depressed adolescents. This finding might be observed because PIU may be the biggest contributor to sleep problems in the problematic Internet user without depression, but in the problematic Internet user with depression, depression might be a more important contributor to sleep problems; thus, the influence of PIU on sleep effect might be diluted.
