Factors associated with positive mental health in Japanese young adults with a history of chronic diseases during childhood: A qualitative study.

PURPOSE: Factors associated with positive mental health in children with chronic diseases remain unclear. Supporting the development of positive mental health in children with chronic diseases can enhance their mental health throughout childhood and adulthood. This study aimed to identify the factors associated with positive mental health among Japanese young adults with a history of chronic pediatric diseases. DESIGN AND METHODS: Participants aged 18-25 years, with a history of chronic pediatric diseases, were recruited from a population of students at a university. Semi-structured interviews were conducted. The data were analyzed using thematic analysis. After the initial coding of each transcript, the researchers discussed and identified a set of main themes, categories, and subcategories. RESULTS: Ten participants aged 19-22 years were interviewed. Their chronic diseases were diverse and included childhood cancers and allergic diseases. Seven themes (proactive coping, positive coping, negative coping, eudaimonia, hedonia, independence, and awareness) emerged from 21 categories and 70 subcategories identified. A thematic map was applied to two domains (protective factors and well-being factors) and to three inter-related constructs (individual, family, and community/society). CONCLUSIONS: The findings indicated that within the well-being factors, meaning in life was prominent, and within the protective factors, stress coping was found to facilitate positive mental health among individuals with a history of chronic pediatric diseases. PRACTICE IMPLICATIONS: In children with chronic diseases, support for finding appropriate coping strategies that enhance their optimism and symbiotic relationships in the community/society are important, including valuing little things in their lives, such as play and learning.

Aquaporins contribute to vacuoles formation in Nile grass type II diabetic rats.

Regulation of ion and water microcirculation within the lens is tightly controlled through aquaporin channels and connexin junctions. However, cataracts can occur when the lens becomes cloudy. Various factors can induce cataracts, including diabetes which is a well-known cause. The most common phenotype of diabetic cataracts is a cortical and/or posterior subcapsular opacity. In addition to the three main types and two subtypes of cataracts, a vacuole formation is frequently observed; however, their origin remains unclear. In this study, we focused on the aquaporins and connexins involved in diabetes-induced cataracts and vacuoles in Nile grass type II diabetes. The results showed that the expression of aquaporin 0 and aquaporin 5 increased, and that of connexin 43 decreased in diabetic rat lenses. Additionally, aquaporin 0 and 5 were strongly localized in peripheral of vacuoles, suggesting that aquaporins are involved in vacuoles formation. Transillumination photography revealed large vacuoles at the tip of the Y-suture in the anterior capsule of the diabetic lens, and several small vacuoles were observed in the posterior capsule. Within the vacuoles, cytoplasmic degradation and aggregation of fibrous material were observed. Our findings suggest that aquaporins are potential candidate proteins for preventing vacuole formation.

Advances in Understanding the Mechanism of Ophthalmic Viscosurgical Device Retention in the Anterior Chamber or on the Corneal Surface during Ocular Surgery.

Retention durability, especially in the eye, is one of the most important properties of ophthalmic viscosurgical devices (OVDs) during ocular surgery. However, the information on the physical properties of OVDs is insufficient to explain their retention durability. The purpose of this study is to clarify the mechanism of OVD retention to improve understanding of the behavior of OVDs during ocular surgery. To elucidate the mechanism of OVD retention, we have developed a new test method for measuring repulsive force. As a result, the maximum repulsive force of OVDs was positively and well correlated with the retention durability of investigated OVDs. Consequently, we demonstrated that the repulsive force could be used as an index of retention durability on the ocular surface and in the eye. We directly compared the intraocular retention durability of three OVDs (Shellgan, Viscoat, and Opegan-Hi) in ex vivo porcine eyes. Opegan-Hi was immediately removed from the anterior chamber, but Shellgan and Viscoat remained largely in the anterior chamber as determined by fluorescence imaging. These results showed that the intraocular retention behavior of OVDs was similar to their ocular surface behavior in our previous report, suggesting that retention durability is dependent on the OVD itself. The retention durability of Shellgan seemed to be higher than that of Viscoat, and the maximum repulsive force of Shellgan was 1.35-fold higher than that of Viscoat. Therefore, the repulsive force might be a useful index for assessing the difference in the retention durability between OVDs such as Shellgan and Viscoat.

Anti-Obesity Effects of Matoa (Pometia pinnata) Fruit Peel Powder in High-Fat Diet-Fed Rats.

Fruit peels, pericarps, or rinds are rich in phenolic/polyphenolic compounds with antioxidant properties and potentially beneficial effects against obesity and obesity-related non-communicable diseases. This study investigated the anti-obesity effects of matoa (Pometia pinnata) and salak (Salacca zalacca) fruit peel. Neither matoa peel powder (MPP) nor salak peel powder (SPP) affected the body weight, visceral fat weight, or serum glucose or lipid levels of Sprague-Dawley rats when included as 1% (w/w) of a high-fat diet (HFD). However, MPP significantly decreased the hepatic lipid level. MPP at a dose of 3% (w/w) of the HFD decreased body weight, visceral fat, and serum triglyceride levels as well as the hepatic lipid content. The inhibitory effect of MPP on hepatic lipid accumulation was not enhanced when its concentration was increased from 1% to 3% of the HFD. The anti-obesity effect of matoa was partly explained by the inhibitory effect of the matoa peel extract on fatty acid-induced secretion of ApoB-48 protein, a marker of intestinal chylomicrons, in differentiated Caco-2 cell monolayers. We identified hederagenin saponins that are abundant in MPP as potential anti-obesity substances. These results will contribute towards the development of functional foods with anti-obesity effects using the matoa fruit peel.

Stressors of School-age Children With Allergic Diseases: A Qualitative Study.

PURPOSE: Most studies of stress in children with chronic diseases have been geared toward parents and caregivers have not considered allergic diseases together. This study aimed to identify the stressors associated with allergic diseases in Japanese school-age children. DESIGN AND METHODS: Stressors associated with allergic diseases of 11 school-age children (seven boys and four girls; age range: 9-12 years) were investigated using semi-structured interviews. RESULTS: In the qualitative thematic analysis of stressors about allergic diseases, two themes: allergic disease-specific stressors and common stressors in chronic diseases, and 12 categories were identified. A thematic map was applied to four domains of stressor: physiological factors, psychological factors, social factors, and environmental factors. CONCLUSIONS: The results showed that school-age children with allergic diseases have a variety of stressors. Future studies should aim to develop an allergic disease-specific stress management program with school-age children. PRACTICE IMPLICATIONS: In children with allergic diseases, not only is stress management in daily life important, but also stress management for disease-specific matters to control the symptoms and maintain mental health. Stress management should be supported for school-age children with allergic diseases.

Stability of ascorbic acid in human aqueous humor.

OBJECTIVE: The stability of ascorbic acid (AA) in the human aqueous humor (AqH) remains unclear. This study aimed to investigate the stability of AqH AA under varying conditions (27, 4, - 20, and - 80 °C) without acidification. RESULTS: Rapid AA degradation occurred at 27 °C. At 4 °C, a significant 12.2% degradation was observed after 24 h. Storage at - 20 °C resulted in a notable 37.5% degradation after 28 days, whereas storage at - 80 °C resulted in 10.7% degradation after 28 days. Unacidified AqH samples recorded early decomposition at 27 °C and 4 °C. In conclusion, it is recommended to conduct measurements within 28 days for samples stored at - 80 °C.

308-nm excimer light is effective for palmoplantar pustulosis regardless of the presence or absence of focal infection: Single-center real-world experience of treatment for palmoplantar pustulosis.

Palmoplantar pustulosis (PPP) is relatively rare and recognition of PPP is different in different countries. Therefore, real-world data are limited. Local phototherapy for the palms and the soles is commonly used to treat PPP due to tolerable safety. However, data on the effectiveness of 308-nm excimer light are limited. In our study, we retrospectively investigated the effectiveness of treatments for PPP, especially phototherapy (308-nm excimer light), in our department. In addition, we examined whether smoking status and focal infection affected responsiveness to treatment of PPP. Patients who were diagnosed with PPP by board-certified dermatologists and visited our hospital from April 2015 to August 2018 were analyzed in this study. We collected data on PPP area severity index (PPPASI) before treatment. We also collected data on PPPASI in May to August 2018 as "after treatment" from all patients. Patients who received any treatment for less than 3 months were excluded. Nineteen patients (16 women and three men) were analyzed in this study. In patients treated with phototherapy (n = 12), PPPASI significantly decreased from a mean ± SD of 16.5 ± 10.3 to 4.5 ± 3.6 (p = 0.004), whereas it did not in patients treated without phototherapy (n = 7). Patients who quit smoking showed a significant decrease in PPPASI after treatment (16.8 ± 12.7 to 2.4 ± 2.9, p = 0.008). Regarding focal infection, in patients treated without phototherapy, the reduction rate of PPPASI was significantly lower in patients with focal infection than in those without focal infection (17.7 ± 21.5%, 71.1 ± 19.3%, p = 0.035), indicating that focal infection is associated with intractability. Meanwhile, in patients treated with phototherapy, PPPASI decreased regardless of the presence or absence of focal infection. In conclusion, our study demonstrated the effectiveness of local phototherapy consisting of 308-nm excimer light, regardless of focal infection. Patients who quit smoking were responsive to any treatment, indicating the importance of smoking cessation.

Interleukin-23 inhibitors decrease Fibrosis-4 index in psoriasis patients with elevated Fibrosis-4 index but not inteleukin-17 inhibitors.

Recent studies indicate that hepatic diseases are associated with psoriasis. Non-invasive tests, including the Fibrosis-4 (FIB-4) index, which can confidently rule out the presence of advanced fibrosis, are currently receiving attention. However, data on the FIB-4 index in psoriasis patients and the effects of biologics on the FIB-4 index are limited. We investigated the relationships between the FIB-4 index and demographic or clinical characteristics as well as the effects of biologics on the FIB-4 index in psoriasis patients. Psoriasis patients aged 36-64 years, whose treatment was initiated with interleukin (IL)-17 inhibitors or IL-23 inhibitors for psoriasis from May 2015 to December 2022, were consecutively included. Data were collected retrospectively from the patients' charts. A total of 171 psoriasis patients were included in this study. Thirty-four, 43, 21, 32, and 41 psoriasis patients were treated with secukinumab, ixekizumab, brodalumab, guselkumab, or risankizumab, respectively. In biologics-naïve patients, a significant but weak positive correlation was observed between the FIB-4 index and age (r = 0.3246, p = 0.0018). There was no significant correlation between the FIB-4 index and other demographic or clinical characteristics. Regarding the effects of biologics on the FIB-4 index, no significant change was observed in psoriasis patients treated with any biologics. However, in psoriasis patients with a baseline FIB-4 index of >1.3, patients treated with guselkumab and those treated with either IL-23 inhibitor showed significantly decreased FIB-4 index scores 6 months after initiating the biologics (p = 0.0323, p = 0.0212). In contrast, no change was observed in FIB-4 index scores in patients treated with IL-17 inhibitors. In conclusion, our study revealed that the FIB-4 index was correlated with age in psoriasis patients. Furthermore, IL-23 inhibitors (but not IL-17 inhibitors) decreased the FIB-4 index score at 6 months in psoriasis patients with elevated FIB-4 index scores at baseline. Further studies are needed to clarify whether IL-23 inhibitors improve liver fibrosis physiologically and functionally.

Oral erosive lichen planus associated with thymoma treated with etretinate.

A 68-year-old Japanese woman was referred to our hospital with a 1-year history of multiple erosions on the oral mucosa and a few pruritic, bean-sized, reddish-blue plaques on the body. Based on physical examination, pathological findings, and immunofluorescence findings, a diagnosis of lichen planus (LP) was made. Computed tomography scan revealed a thymoma. After thymectomy, cutaneous LP lesions subsided spontaneously. Oral lesions responded well to oral etretinate therapy. We speculate that direct tissue injury by CD8(+) T cells, activated by abnormal regulation of lymphocytes within the thymus, may cause LP.

Relationship between anterior capsule opening and direction of intraocular lens decentration.

PURPOSE: To compare intraocular lens (IOL) decentration between patients in whom the continuous curvilinear capsulorhexis (CCC) completely covers the IOL optic and those in whom it incompletely covers the IOL optic and determine how an incompletely covered CCC affects the IOL position. SETTING: Tertiary hospital in Japan. DESIGN: Single-center retrospective study. METHODS: 57 eyes of 57 patients (mean age 70.8 ± 6.2 years) that underwent phacoemulsification and IOL (SN60WF) implantation in the bag between April 2010 and April 2015 were included in this study. The patients were classified based on whether the CCC completely (CC group) or incompletely (NCC group) covered the IOL optic using an anterior eye segment analysis system (EAS-1000). The IOL decentration of the groups was analyzed using EAS-1000 at 1 week, 1 month, 3 months, and 6 months postoperatively and compared. The relationship between the NCC location and the IOL direction at 3 months postoperatively was analyzed. RESULTS: The NCC group (25 eyes) had a significantly higher amount of IOL decentration than the CC group (32 eyes) at 1 week, 1 month, 3 months, and 6 months postoperatively ( P < .05). There was a correlation between the direction of IOL decentration and the NCC location, and IOL decentration in the NCC group occurred in the opposite direction to the NCC area. CONCLUSIONS: An anterior capsule opening that completely covers the IOL optic is important to control IOL decentration.

Inhibition of anterior capsule opacification and contraction by the elevated anterior rim of the intraocular lens optic.

PURPOSE: To verify the anterior capsule opacification (ACO) and contraction (ACC) of the ZCB00V intraocular lens (IOL), made of the same material as the AR40e with a high ACC rate. STUDY DESIGN: Retrospective cohort study. METHODS: We evaluated 35 patients at 1 week, 1, 3 and 6 months post phacoemulsification with either a ZCB00V (n = 35) or FY-60AD (n = 34) IOL implantation. The ACC rate was calculated using retroillumination images of the anterior segment, and the ACO was measured using anterior segment photographs and image analysis software. The contact grade between the IOL and anterior capsule was estimated from the Pentacam® images. RESULTS: The postoperative ACC rates (mean ± standard deviation) at 3 months were 1.03%±2.54% for the ZCB00V and, and 7.12%±9.47% for the FY-60AD. The ZCB00V-implanted eyes showed a significantly lower postoperative ACC at 1 week, 3 months, and 6 months (P < 0.01). On the other hand, the FY-60AD-implanted eyes had more pronounced ACO, and a significantly larger area of opacification (62.24%±21.32% vs. 16.90%±8.34%; P = 0.0005). Pentacam® analysis revealed a space between the anterior capsule and IOL surface in the ZCB00V-implanted eyes, whereas the anterior capsule firmly adhered to the IOL surface in the FY-60AD-implanted eyes. CONCLUSION: The ACC and ACO were significantly lower in eyes with ZCB00V IOLs compared to those with the FY-60AD. The anterior segment image analysis revealed that the elevated anterior rim of the ZCB00V IOL prevented adhesion between the anterior capsule and IOL optic surface, suggesting an open capsule effect.

Prophylactic Treatment for Patients with Migraine Using Blue Cut for Night Glass.

Objectives Migraine is a disease that leads to social loss due to a decrease in productivity since it is a primary headache with a high prevalence and readily occurs in working-age persons. As described in the diagnostic criteria of the International Classification of Headache Disorders, 3rd edition (beta version), migraine causes hypersensitivity, especially photosensitivity, during attacks, suggesting that light is an inducer of headaches. We developed Blue Cut for Night (BCN) glass, which reduces light stimulation to intrinsically photosensitive continental ganglion cells (ipRGCs), photoreceptors that can lead to exacerbation of migraine attacks. Methods Ten patients with migraine participated in the study. Each participant was made to wear BCN glasses only at night for four weeks. The number of headache days and Headache Impact Test-6 values before and after using the BCN glasses were compared. Results When the 10 patients with migraine wore the BCN glass at night only for 4 weeks, the number of headache days within that time tended to decrease (7.0±4.37 days) compared to before wearing the glasses (8.7±5.03 days). No participants had any side effects. Conclusion BCN glass, which reduces light stimulation to ipRGCs, was suggested to be a tool for reducing migraine attacks.

Clinical Features of Syphilis Patients with Ocular Symptoms as the Initial Manifestation.

Purpose: This study aimed to investigate the clinical features of patients with syphilis having ocular symptoms as the initial manifestation. Patients and Methods: Eleven patients diagnosed with ocular syphilis at Dokkyo Medical University Hospital and Jichi Medical University Hospital between November 2018 and April 2022 were studied retrospectively. Results: Six patients were diagnosed with secondary, three were latent, and one was tertiary stage syphilis. Ten out of 11 patients underwent cerebrospinal fluid analysis, and 1 refused. Nine out of 10 patients tested positive, of which 4 presented with neurological symptoms and the others were asymptomatic. Nine out of 11 patients tested negative for human immunodeficiency virus. Antiluetic therapy was administered to 10 out of 11 patients, which improved or maintained visual acuity at -0.1 logMAR in 9 patients. One patient achieved the best-corrected visual acuity -0.1 logMAR in one eye, whereas the other showed no improvement due to severe chorioretinal degeneration. Conclusion: Ocular syphilis presents with various clinical findings and has no significant ocular manifestations without acute syphilitic posterior placoid chorioretinitis. Patients diagnosed with syphilis based on ocular symptoms should undergo cerebrospinal fluid analysis.
