PURPOSE: To evaluate the clinical outcomes of small incision lenticule extraction (SMILE) for the treatment of myopia with corneal opacity. METHODS: Thirteen eyes of 13 patients with corneal opacities who underwent SMILE were retrospectively studied. Uncorrected distance visual acuity, spherical equivalence, efficacy index, and safety index were noted at 3 months after the procedure. The density and area of the corneal opacities were measured and compared preoperatively and 3 months postoperatively. RESULTS: All eyes had preoperative corneal opacities within the lenticule formation areas. The mean area and density of corneal opacities were 0.72 ± 0.33 mm2 and 52.46 ± 15.74, respectively. All procedures were uneventful and no intraoperative complications were observed. At 3 months after the procedure, the efficacy and safety indices were 1.01 ± 0.15, and 1.05 ± 0.10, respectively, and the mean densities and areas of corneal opacities were 46.85 ± 14.56 (p = 0.038) and 0.70 ± 0.36 mm2 (p = 0.776), respectively. CONCLUSIONS: The SMILE procedure was effective and safe for the correction of myopic patients with corneal opacities.

Objective: To translate the Brief Resilience Scale into Korean and evaluate its reliability and validity. Methods: To investigate the factor structure of the Brief Resilience Scale, we examined a two-factor model comprising positively and negatively worded items. Congruent and divergent validity of the Brief Resilience Scale were investigated using correlation analysis between the Brief Resilience Scale and resilience, depression, and perceived stress. By conducting an analysis of variance among groups classified by suicidality (no suicidality, only suicidal ideation, and suicidal ideation or suicidal plan groups), we evaluated how well the Brief Resilience Scale could detect people with a high risk of suicide. Results: Confirmatory factor analysis results supported the construct validity of the Brief Resilience Scale using a two-factor model. Cronbach’s alpha (0.91) and McDonald’s omega (0.91) scores indicated high internal consistency. Correlation analysis showed that the Brief Resilience Scale scores were strongly associated with a questionnaire evaluating resilience, depression, and perceived stress. Analysis of variance and post-hoc tests showed that he Brief Resilience Scale scores were highest in the no suicidality group (p ＜ 0.001). Conclusion The Korean version of the Brief Resilience Scale is a valid and reliable instrument for evaluating resilience as the capacity to recover from adversity and endure obstacles or stress. This study also provides important evidence regarding the sensitivity of the Brief Resilience Scale to suicidal risk.

Objective: Research on the association between posttraumatic embitterment disorder (PTED) and other psychopathologies in veterans and adults aged ≥65 years is lacking. This study aimed to assess embitterment among elderly war veterans and its association with major psychopathological factors. Methods: Participants included Vietnam War veterans who visited a psychiatric clinic. Based on the Posttraumatic Embitterment Disorder Self-Rating Scale (PTEDS) score, the participants were divided into the embitterment (PTED(+), mean score of PTEDS items [mPTEDS] ≥1.6) and non-embitterment (PTED(-), mPTEDS <1.6) groups. Demographic characteristics, combat exposure severity, depression, anxiety, sleep, and alcohol use disorder symptom scores of the participants were collected and compared between the PTED(+) and PTED(-) groups. A correlation analysis between symptom measure scores and the mPTEDS was conducted. The influence of psychopathology on embitterment was investigated using stepwise multiple linear regression analysis. Results: In total, 60 participants (28 in PTED(+) and 32 in PTED(-)) were included. Among those in PTED(+), 21 (35.0%) showed mild embitterment symptoms (1.6≤ mPTEDS <2.5) and 7 (11.7%) reported moderate or severe embitterment symptoms (mPTEDS ≥2.5). The mean scores of posttraumatic stress disorder (PTSD), depression, and anxiety were significantly higher in the PTED(+) than in the PTED(-) group. The mPTEDS were significantly correlated with PTSD, depression, anxiety, and sleep disorder scores. The PTSD symptoms significantly explained the higher mPTEDS score in a regression model. Conclusion Embitterment symptoms were associated with PTSD, depression, anxiety, and insomnia symptoms in elderly veterans, similar to the results of prior studies involving only the general population.

OBJECTIVE: Silent corticotroph adenomas (SCA) are endocrine-inactive pituitary adenomas with positive immunohistochemistry staining for adrenocorticotropic hormone (ACTH). We investigated whether SCA-associated clinical profiles were more aggressive than hormonally negative adenomas (HNA).METHODS: Among 627 patients with pathologically proven endocrine-inactive pituitary adenomas between 2004 and 2013, positive immunohistochemistry revealed 55 SCAs and 411 HNAs. Surgical outcomes and radiological and endocrinological characteristics were compared.RESULTS: Strong female predominance was observed in the SCA group (p<0.001). Cavernous sinus invasion was identified in 22 (40%) SCA patients and 72 (17.6%) HNA patients (p<0.001). There were no differences in ACTH or cortisol levels between the two groups. The incidence of preoperative hypopituitarism and postoperative hormonal outcome did not differ between two groups. Total resection was achieved in 35 patients (63.7%) with SCA and 332 patients (80.8%) with HNA (p=0.007). When tumors were completely removed, recurrence rates were not statistically different between two groups (p=0.60). When complete resection was not achieved, tumors regrew from these remnants in seven patients (35.0%) with SCA and 12 patients (15.2%) with HNA (p=0.05).CONCLUSION: Total surgical resection for SCA is often challenging as these tumors frequently invade a cavernous sinus. Early remnant tumor intervention is justified, because untreated residual pituitary tumors regrow when patients were followed up for a long time. Prophylactic radiotherapy is not warranted for completely resected SCAs as tumor recurrence is uncommon.

Objective: While the association between depression and frailty in the elderly population has been investigated, the psychological factors that mediate such a relationship remain unknown. The identification of psychological factors in interventions for depression treatment in the elderly may assist in the treatment and care. We aimed to explore the mediating effects of anger, anxiety, and resilience on the link between frailty and depression symptoms in patients with late-life depression. Methods: A sample of 203 older adults completed questionnaires that assessed depression, anger, resilience, and anxiety.To measure frailty, participants were evaluated using a self-rated health questionnaire, weight-adjusted waist index related to sarcopenia, and weight-adjusted handgrip strength to evaluate weakness. A mediation model was tested, hypothesizing that anger, anxiety, and resilience would partially mediate the strength of the frailty-depression link in the elderly. Results: Only self-rated health showed a significant association with depressive symptoms in late-life depression. Our study demonstrated that frailty has both direct and indirect associations with depression, mediated by anger, resilience, and anxiety. Conclusion Given that anger, resilience, and anxiety influence the link between self-rated health and depression, interventions that lead to increased resilience and decreased anger and anxiety may be promising to reduce depressive symptoms in older adults with depression.

Dysfunction of mitochondrial metabolism is implicated in cellular injury and cell death.While mitochondrial dysfunction is associated with lung injury by lung inflammation, the mechanism by which the impairment of mitochondrial ATP synthesis regulates necroptosis during acute lung injury (ALI) by lung inflammation is unclear. Here, we showed that the impairment of mitochondrial ATP synthesis induces receptor interacting serine/threonine kinase 3 (RIPK3)-dependent necroptosis during lung injury by lung inflammation. We found that the impairment of mitochondrial ATP synthesis by oligomycin, an inhibitor of ATP synthase, resulted in increased lung injury and RIPK3 levels in lung tissues during lung inflammation by LPS in mice. The elevated RIPK3 and RIPK3 phosphorylation levels by oligomycin resulted in high mixed lineage kinase domain-like (MLKL) phosphorylation, the terminal molecule in necroptotic cell death pathway, in lung epithelial cells during lung inflammation. Moreover, the levels of protein in bronchoalveolar lavage fluid (BALF) were increased by the activation of necroptosis via oligomycin during lung inflammation.Furthermore, the levels of ATP5A, a catalytic subunit of the mitochondrial ATP synthase complex for ATP synthesis, were reduced in lung epithelial cells of lung tissues from patients with acute respiratory distress syndrome (ARDS), the most severe form of ALI. The levels of RIPK3, RIPK3 phosphorylation and MLKL phosphorylation were elevated in lung epithelial cells in patients with ARDS. Our results suggest that the impairment of mitochondrial ATP synthesis induces RIPK3-dependent necroptosis in lung epithelial cells during lung injury by lung inflammation.
