Does tomato juice consumption have a positive effect on the physical and psychological states of individuals in the Coronavirus era?

OBJECTIVES: This preliminary study aims to examine the effects of tomato juice, which can be easily consumed regularly, on the physical and psychological states of healthy adults in the Coronavirus era. DESIGN: Prospective observational study. MATERIALS AND METHODS: Ten healthy adults (mean age, 39.7±4.2 years) who consumed 180 mL of tomato juice twice daily for 4 weeks were enrolled. Measurements were taken before and after 4 weeks of consumption for the items below. Five salivary stress biomarkers (cortisol, α-amylase, secretory immunoglobulin A, chromogranin A, and oxytocin) were measured using approximately 1ml of passively pooled saliva samples, which were stored at -20°C until measurement. Autonomic nervous system (ANS) activity was evaluated using an acceleration pulse wave meter. Skin moisture content and transepidermal water loss (TEWL) were measured using Multi Display devices® MDD4 with specific probes. Subjective psychological states were assessed using Profile of Mood Status (POMS2®) and a survey on skin condition was conducted. RESULTS: As for salivary stress biomarkers, tomato juice intake reduced cortisol and significantly increased oxytocin levels (p = 0.0427). No significant changes were observed in ANS activity. POMS2® results showed a significant decrease in confusion and bewilderment (p = 0.0207). Skin moisture content increased significantly (p = 0.0011), whereas TEWL decreased. The skin condition survey revealed significant changes in 10 parameters. CONCLUSIONS: Tomato juice, which can be easily consumed regularly, may alleviate the stress of healthy adults in the Coronavirus era, supported by positive changes in salivary stress biomarker levels, skin moisture content, TEWL, and POMS2® results of this preliminary study.

Differences in the diurnal variation of salivary stress biomarkers during the coronavirus (COVID-19) pandemic between telecommuters and office workers.

OBJECTIVES: It is necessary to objectively assess the stress state of workers, from the standpoint of holistic palliative care, in order to determine how the rapid change in work styles in the "live with coronavirus era"-in which people will coexist and live with the coronavirus (COVID-19)-will affect their physical and mental health. The aim of this study is to assess the impact of rapid changes in work patterns during the COVID-19 pandemic on the neuroendocrine stress response of workers. DESIGN AND METHODS: A total of sixteen subjects, 9 telecommuters (2 males, 7 females; age, 37.1±2.6 years) and 7 office workers (3 males, 4 females; age, 37.3±3.0 years) who provided their informed consent were enrolled in this prospective observational study. Saliva was collected four times a day (after waking, noon, evening, and before bedtime) and three times a week (Monday, Wednesday, and Friday) during May and June 2020. The saliva samples were stored at -20°C until measurement. Saliva components were analyzed by ELISA for cortisol, melatonin, s-IgA, and oxytocin. RESULTS: The diurnal variation of salivary components between telecommuting and office work groups was investigated. Cortisol showed diurnal variation with higher secretion during waking hours and lower secretion toward nighttime in both groups, and no modulation was observed. In the office work group Melatonin showed diurnal variation, with increased secretion at night. In contrast, the telecommuting group showed modulation, with higher secretion at waking and lower secretion at night. s-IgA showed diurnal variation with a high level at waking and a low level thereafter in both groups, and no modulation was observed. The telecommuting group showed higher oxytocin levels in comparison to the office work group. CONCLUSIONS: These results suggest that the absence of commuting in the telecommuting group reduces anxiety due to infection, and that the diurnal variation of melatonin may be due to the alteration of circadian rhythm caused by being at home all day.

Surgical Success Rate of Scleral Buckling Surgery and Postoperative Incidence of Cystoid Macular Edema: 10 Years of Experience at a Single Academic Hospital.

The purposes of this study were to report the surgical success rate of scleral buckling surgery (SB) for rhegmatogenous retinal detachment (RRD) in a single academic hospital, analyze the incidence of cystoid macular edema (CME) after SB using optical coherence tomography (OCT), and reveal the factors associated with the development of CME. This was a retrospective observational study of patients with RRD who underwent SB from 2010 to 2020 in a single academic hospital. The anatomical success was initially achieved in 267 of 288 eyes (92.7%), and finally achieved in 288 eyes (100%). After excluding 17 eyes that underwent vitrectomy for reoperations, a total of 271 eyes of 267 patients (173 men; age, 43.5 ± 16.9 years) were retrospectively analyzed to evaluate the incidence of postoperative CME. CME occurred in 6 of 271 eyes (2.2%) within 3 months after initial surgery. Pseudophakic and aphakic eyes appeared more likely to develop CME (chi-squared test: p = 0.0078). Five of the six cases with postoperative CME were able to be medically treated. Scleral buckling surgery showed a high success rate even in the era of small-gauge vitreous surgery, and the postoperative frequency of CME after SB was low (2.2%). Previous cataract surgery may be associated with the development of postoperative CME, which is mostly medically manageable.

ONE-YEAR OUTCOMES OF METAMORPHOPSIA AND RETINAL DISPLACEMENT AFTER EPIRETINAL MEMBRANE SURGERY.

PURPOSE: To examine 1-year outcomes of metamorphopsia and tangential retinal displacement after epiretinal membrane surgery and identify predictors for metamorphopsia score at 1 year and its improvement from baseline. METHODS: M-CHARTS were used to measure metamorphopsia. Distances between the intersections of two sets of retinal vessels were measured with infrared or autofluorescence images. Predictors for metamorphopsia scores at 1 year after surgery and their differences from baseline were identified with multivariate regression analysis. RESULTS: Ninety-two eyes of 90 consecutive patients were included. The vertical and horizontal distances continued expanding for 1 year ( P < 0.001). Both vertical and horizontal metamorphopsia scores improved 3 months after surgery ( P = 0.025 and P < 0.001, respectively), and horizontal scores continued improving for a year. Horizontal metamorphopsia scores correlated with retinal displacement more strongly than vertical scores. Higher metamorphopsia score at baseline is predictive for that at 1 year. Older age and being male are predictive for less improvement of the score at 1 year from baseline. CONCLUSION: Metamorphopsia correlates with tangential retinal displacement at 1 year after epiretinal membrane surgery. Horizontal metamorphopsia scores keep improving until 1 year postoperatively. Being male and older age are both independent predictors for poor improvement of metamorphopsia after epiretinal membrane surgery.

Comprehensive assessment of the impact of horticultural activities on salivary stress biomarkers, psychological status, and the autonomic nervous system response visualized using a wearable biosensor.

OBJECTIVES: This study aims to comprehensively investigate the changes of salivary stress biomarkers, psychological status, and autonomic nervous system (ANS) response due to horticultural activities (HAs). DESIGN AND METHODS: A prospective observational study was conducted in twenty Japanese healthy adults (mean age, 58.4 years). Flower appreciation, flower arrangement, and farm work experience were performed as three HAs with different working concepts. Five salivary stress biomarkers (cortisol, α-amylase, S-IgA, chromogranin A, and oxytocin) were measured to quantify the stress levels before and after each HA. The Profile of Mood Status 2nd edition (POMS2) was used as a subjective psychological evaluation. Wearable biosensors were used to visualize the continuous ANS response throughout the process. RESULTS: In the POMS2 investigation, the negative factors, which included Anger-Hostility, Confusion-Bewilderment, Depression-Dejection, Tension-Anxiety, and Total Mood Disturbance, were significantly decreased (p=0.0135, p=0.0004, p=0.0024, p=0.0015, p=0.0063, respectively). In the measurement of salivary stress biomarkers, flower appreciation decreased cortisol (p=0.0134), and farm work experience not only decreased cortisol but also increased oxytocin (p=0.0041, p=0.0128 respectively). In the visualization results of the ANS response, a graph demonstrated that the difference in activity between the sympathetic nerve and the parasympathetic nerve was narrowed by a series of HAs. CONCLUSIONS: In healthy adults, HAs had a stress-reducing effect, which was evidenced by neuroendocrinological and psychological evaluations, a study of POMS2, salivary stress biomarkers, and visualization of the ANS response.
