Reactivation of Epstein-Barr virus (EBV) is associated with the etiopathogenesis of a broad spectrum of diseases. This study aimed to investigate the association between psychological distress and EBV serological reactivation among community-dwelling older people and assess the role of sex differences in this association. This population-based cross-sectional survey was conducted among individuals who underwent annual health checkups (N = 2,821; median age 72.4 years). EBV serological reactivation was defined as elevation of EBV early antigen immunoglobulin G titers, and psychological distress was defined as Kessler 6 scores ≥5. Multivariable logistic regression analysis was performed to calculate odds ratios (OR) and 95% confidence intervals (CI) for EBV serological reactivation and psychological distress. EBV serological reactivation and psychological distress were detected in 16.4% and 8.7% of participants, respectively. Women accounted for 71% (328/463) of those with EBV serological reactivation. Multivariable logistic regression analysis showed psychological distress was not significantly associated with EBV serological reactivation among all participants (OR 1.31, 95% CI: 0.95, 1.82; P = 0.102). A sex-stratified multivariable analysis showed a positive association among women (OR 1.45, 95% CI: 1.01, 2.08; P = 0.043), but no association among men. EBV serological reactivation was independently associated with psychological distress in community-dwelling older women. The sex difference in our results warrants further investigation to clarify the physiological mechanisms underlying the association.
Using random dots blinking (RDB), which reflects the activity of the higher visual area related to face perception, the following stimuli were presented. (1) Upright: a schematic face; (2) Inverted: the Upright stimulus inverted; and (3) Scrambled: the same contour and features as in Upright but with the spatial relation distorted. Clear negative components (N-ERP250) were identified at approximately 250 ms after stimulus onset. At the T5 and T6 electrodes, the peak latency was significantly longer for Inverted and Scrambled than for Upright. At the P4 electrode, the maximum amplitude was significantly larger for Scrambled than for Upright and Inverted. These results indicate that the delayed latency for Inverted and Scrambled reflects the involvement of the additional analytic processing caused by the configural distortion, and that the increase in amplitude for Scrambled indicates the existence of further processing caused by the distortion of the spatial relationship between the contour and features.
This study investigated whether breastfeeding predicts offspring’s dispositional compassion and empathy from early adulthood to middle age. The parents of the participants ( N = 1,394) of the Young Finns study answered questions about breastfeeding in 1983, and the participants’ compassion and empathy were evaluated in 1997‒2012 (participants were aged 20‒50 years). Breastfeeding did not predict the course of compassion or empathy in adulthood at the age of 20‒50 years. The associations remained non‐significant, when adjusted for age, gender, socioeconomic factors, and a wide range of characteristics of the family environment (including mother’s gestational age; premature birth; birth weight; number of other children at home; parental mental disorder; parental relationship status; parental postnatal smoking; parental postnatal alcohol use; parenting behavior; and child’s externalizing behavior). In conclusion, breastfeeding seems not to predict offspring’s compassion or empathy in adulthood. The findings may present a hopeful perspective for children growing up with non‐breastfeeding caregivers.
In head and neck squamous cell carcinoma (HNSCC) treatment, extended waiting times for chemoradiotherapy negatively impact survival outcomes. Identifying contributing factors to these delays and strategies to minimize them could improve the prognosis for HNSCC patients. However, the factors affecting treatment delays remain incompletely understood, warranting further investigation. This retrospective study examined the association between patient residence and treatment delay. Medical records of 125 patients with squamous cell carcinoma of the oropharynx, hypopharynx, or larynx, treated with radiotherapy or chemoradiotherapy at the Department of Otolaryngology, Nagasaki University School of Medicine, were analyzed. Treatment delay was defined as the period from the patient's initial medical visit to the start of treatment at our hospital. The relationship between factors, such as patient location and waiting period, was assessed. Uni- and multivariate logistic regression analyses revealed that residing in a remote area was significantly associated with longer treatment delays (OR: 4.41, 95% CI: 1.40-13.91, p = 0.01; adjusted OR: 7.60, 95% CI: 1.93-29.98, p < 0.01). These findings underscore the need for interventions to reduce treatment delays in HNSCC patients from remote areas.
