Bright Morning Lighting Enhancing Parasympathetic Activity at Night: A Pilot Study on Elderly Female Patients with Dementia without a Pacemaker.

Exposure to bright morning light (BML) entrains the master circadian clock, modulates physiological circadian rhythms, and reduces sleep-wake disturbances. However, its impact on the autonomic nervous system at night remains unclear. Here, we investigated the effects of BML exposure on parasympathetic nervous system (PSNS) and sympathetic nervous system (SNS) activity at night in elderly women. This nonrandomized controlled pilot study included female participants aged ≥ 60 years who were diagnosed with a type of dementia or cognitive disorder, excluding individuals with pacemakers. The treatment group was exposed to 2500 lx of BML, whereas the control group was exposed to 200 lx of general lighting. We measured heart rate variability to quantify ANS activity. The treatment group displayed significant increases in high-frequency (HF) power (Roy's largest root = 1.62; p < 0.001) and nonsignificant decreases in normalized low-frequency (LF%) power. The corresponding nonsignificant decreases in the low-frequency/high-frequency (LF/HF) ratio and cognitive function were correlated with PSNS activity (Roy's largest root = 1.41; p < 0.001), which improved severe dementia. BML exposure reduced SNS activity and enhanced PSNS activity at night in female participants, which improved cognitive function. Thus, BML therapy may be a useful clinical tool for alleviating cognitive decline.

Intravitreal aflibercept combined with transpupillary thermotherapy in the treatment of refractory macular edema due to primary uveal melanoma.

We reported a 74 year old Asian female with a uveal tumor with subretinal fluid (SRF) and cystoid macula edema. Since she declined biopsy, multimodal imaging study was performed, including fundus photography, ultrasonography, optical coherence tomography, fluorescein angiography, and magnetic resonance imaging. Uveal melanoma was diagnosed. However, despite aggressive treatment with TTT and three adjuvant intravitreal bevacizumab doses, SRF, and cystoid macula edema were persistent. Therefore, aflibercept was administered, resulting in anatomical and functional improvement within 1 month, which lasted for 12 months. Aflibercept offered great efficacy in improving refractory macular edema in this case of primary uveal melanoma. Multimodal imaging can provide us with more diagnostic clues in differentiating the nature of intraocular tumors.

Disclosure of suboptimal health status through traditional Chinese medicine-based body constitution and pulse patterns.

OBJECTIVES: Suboptimal health status (SHS) is a dynamic state wherein people have not been diagnosed with a disease but tend to develop diseases. People with SHS often experience fatigue and other nonspecific symptoms, which are related to a deviated body constitution in traditional Chinese medicine (TCM). However, the correlation between TCM constitution and SHS has not been adequately investigated. Furthermore, no study has explored the radial pulse analysis-an assistive objective indicator of TCM constitution-in healthy people and people with SHS. DESIGN: A cross-sectional study. SETTINGS/LOCATION: Center for Traditional Medicine, Taipei Veterans General Hospital, Taiwan. SUBJECTS: Sixty-six adults (27 healthy participants and 39 participants with SHS) who were aged 20-39 years. OUTCOME MEASURES: The body constitution questionnaire (BCQ) scores, suboptimal health status questionnaire-25 (SHSQ-25) scores, and radial pulse waves detected using sphygmography were recorded. Pulse wave analyses are presented as the ratio of frequency below 10 Hz to that above 10 Hz (SER10), which represent energy changes in organ blood flow. RESULTS: Participants with SHS had significantly higher Yang-Xu, Yin-Xu, and stasis scores of BCQ compared with healthy participants. The SHSQ-25 scores of the participants with SHS were moderately correlated with their Yang-Xu, Yin-Xu, and stasis scores (r = 0.65, 0.66, and 0.72, respectively; all p < 0.001), but weak correlations were discovered for healthy participants. The participants with SHS had significantly higher SER10 at the left guan (the "liver" system in TCM) than did the healthy participants. CONCLUSIONS: SHS is moderately correlated with TCM-based constitution and those with SHS had increased SER10 at the leftguan of the radial pulse.

Relationship between Uveitis and Thyroid Disease: A 13-Year Nationwide Population-based Cohort Study in Taiwan.

Purpose: To investigate whether patients with thyroid disease are at increased risk of uveitis.Methods: Data was collected from the Taiwan National Health Insurance system and included patients newly diagnosed with thyroid disease from 2000 to 2012. The endpoint of interest was a diagnosis of uveitis.Results: In analyzing 21,396 patients with thyroid disease, yielding 85,584 matched comparisons, patients with thyroid disease to have a significantly higher cumulative incidence of uveitis when compared to the control cohort with the Kaplan-Meier analysis. This result was further confirmed by Cox regression analysis. The increased risk was persistent in both genders. The association between thyroid disease and uveitis was stronger in patients without diabetes or hypertension.Conclusion: Patients with thyroid disease were found to have a higher risk for uveitis. For certain age groups or patients without diabetes or hypertension, the role of thyroid disease might be more crucial for uveitis development.
