RESUMEN
Our study compared treatment efficacy between cut-off and notch filters in intense pulsed light (IPL) therapy for meibomian gland dysfunction (MGD) through a prospective, randomized paired-eye trial. Additionally, the efficacy of IPL treatment alone was investigated by restricting other conventional treatments. One eye was randomly selected for an acne filter and the other for a 590-nm filter. Identical four regimens of IPL treatments were administered. The tear break-up time (TBUT), Oxford scale, Sjögren's International Clinical Collaborative Alliance (SICCA) staining score, tear matrix metalloproteinase-9 (MMP-9) expression, tear osmolarity, and Ocular Surface Disease Index (OSDI) questionnaires were evaluated before and after IPL. Meibomian gland (MG) parameters were measured. When combining the results from both filters, the TBUT, SICCA staining score, OSDI score, and upper and lower lid meibum expressibility were improved after IPL. No significant differences were found between the two filters in the TBUT, Oxford scale, SICCA staining score, MMP-9 expression, tear osmolarity, and MG parameters. Although not significant, the acne filter showed better treatment efficacy than that in the 590-nm filter. IPL alone is efficacious in terms of ocular surface parameters, MG function, and subjective symptoms. Regarding filter selection, both acne and 590-nm filters are promising options for MGD treatment.

PURPOSE: We investigated the subjective and objective outcome after intense pulsed light (IPL) treatment and meibomian gland expression on the upper and lower eyelids compared with those after IPL treatment on the lower eyelid alone in patients with moderate-to-severe meibomian gland dysfunction (MGD). METHODS: Patients who underwent four IPL treatment sessions with meibomian gland expression were divided into upper and lower treatment group and conventional treatment group treated with lower eyelid alone. All patients underwent an ophthalmologic examination and answered a symptom questionnaire before the first treatment and 1 month after the last treatment. An ophthalmologic examination included tear break-up time (TBUT), fluorescein staining score, Schirmer's test, matrix metalloproteinase-9 (MMP-9), meibum grade, color, consistency, and lid margin telangiectasia. Additionally, visual acuity and adverse effects were checked on every visit. RESULTS: Of 115 patients, 75 in the upper and lower treatment group and 40 in the conventional treatment group were included. TBUT, fluorescein staining score, subjective symptom, and meibum grade were significantly improved in both groups. Additionally, meibum color and consistency of upper and lower eyelids significantly decreased post-treatment in both groups. The lid margin telangiectasia of the upper and lower eyelids significantly decreased post-treatment in the upper and lower treatment group. MMP-9 positivity and grading scores significantly decreased post-treatment in both groups, and no severe adverse effects occurred during the follow-up period. CONCLUSION: Additional IPL treatment on the upper eyelid using a protective device was proven safe and provided an additive improvement in treating moderate-to-severe MGD.

Many plants have been used in Korean medicine for treating insomnia. However, scientific evidence for their sedative activity has not been fully investigated. Thus, this study was carried out to investigate the sedative effects of the extracts of medicinal plants, including Yukmijihwang-tang and its various modified forms through the 5-HT2c receptor binding assay, and to further confirm its sleep-promoting effects and the underlying neural mechanism in rats utilizing electroencephalography (EEG) analysis. Enzyme-linked immunosorbent assay (ELISA) was used to measure serotonin (5-HT) in the brain. The water extracts of modified Yukmijihwang-tang (YmP) displayed binding affinity to the 5-HT2C receptor (IC50 value of 199.9 µg/mL). YmP (50 mg/kg) administration decreased wake time and increased REM and NREM sleep based on EEG data in rats. Additionally, treatment with YmP significantly increased the 5-HT level in the hypothalamus. In conclusion, the sedative effect of YmP can be attributed to the activation of the central serotonergic systems, as evidenced by the high affinity of binding of the 5-HT2C receptor and increased 5-HT levels in the brain of the rat. This study suggests that YmP can be a new material as a sleep inducer in natural products.
RESUMEN
PURPOSE: To evaluate the combined effect of intense pulsed light (IPL) therapy and meibomian gland expression on extracellular matrix metalloproteinase-9 (MMP-9) levels and clinical outcomes of moderate and severe meibomian gland dysfunction (MGD) treatment. METHODS: This retrospective study was conducted on 45 eyes of 23 patients with moderate and severe MGD. Each eye underwent three IPL sessions and meibomian gland expression at 2-week intervals. In this study the evaluated parameters included tear film break-up time (TBUT), corneal and conjunctival fluorescein staining scores, biomicroscopic examination of lid margins and meibomian glands, ocular surface disease index (OSDI) questionnaire score, and extracellular MMP-9 levels using the immunoassay device before and two weeks after the last treatment session. Linear mixed model and generalized estimating equations model were used to evaluate possible differences. RESULTS: There were significant improvements in TBUT (P < 0.001), SICCA ocular staining score (P = 0.008), Oxford staining score (P = 0.023), lid margin irregularity (P < 0.001 for upper and lower eyelids), lid thickness (P < 0.001 for upper and lower eyelids), meibomian gland plugging (P = 0.010 and P = 0.012 for upper and lower eyelids), meibum color (P = 0.044 and P < 0.001 for upper and lower eyelids), meibum consistency (P < 0.001 for upper and lower eyelids), MGD grade (P < 0.001), and OSDI questionnaire score (P < 0.001). Incidence of positive results for MMP-9 immunoassay significantly decreased from 84.0% to 56.0% (P = 0.031) after treatment. CONCLUSION: In patients with moderate to severe MGD, three sessions of IPL combined with meibomian gland expression improved objective findings, subjective symptoms, meibomian gland function, and MMP-9 immunoassay results. The results support the combination of IPL and meibomian gland expression for treating moderate to severe MGD.

Importance: Response-adapted randomized trials have used positron emission tomography-computed tomography to attempt to identify patients with early-stage favorable Hodgkin lymphoma (ESFHL) who could be treated with doxorubicin, bleomycin, vinblastine, and dacarbazine (ABVD) without radiation therapy (RT). While maximal efficacy is demonstrated with combined modality therapy, RT is often omitted in fear of late adverse effects; however, the application of modern RT could limit these toxic effects. Objective: To determine the radiation doses delivered to organs at risk with modern involved-site RT among patients with ESFHL treated with 20 Gy after 2 cycles of ABVD. Design, Setting, and Participants: This case series included 42 adult patients with ESFHL (according to the German Hodgkin Study Group criteria) who were treated between 2010 and 2019, achieved complete response by positron emission tomography-computed tomography (1-3 on 5-point scale) following 2 cycles of ABVD, and then received consolidative RT. The study was conducted at a single comprehensive cancer center. Exposures: 2 cycles of chemotherapy followed by 20-Gy involved-site RT. Main Outcomes and Measures: The medical records of patients with ESFHL were examined. Organs at risk were contoured, and doses were calculated. Progression-free survival, defined from date of diagnosis to disease progression, relapse, or death, and overall survival were estimated using the Kaplan-Meier method. Results: The cohort comprised 42 patients with ESFHL (median [range] age at diagnosis, 35 [18-74] years; 18 [43%] women; 24 [57%] with stage II disease). At a median follow-up of 44.6 (95% CI, 27.6-61.6) months, the 3-year progression-free survival and overall survival rates were 91.2% (95% CI, 74.9%-97.1%) and 97.0% (95% CI, 80.4%-99.6%), respectively. The mean heart dose was less than 5 Gy (mean, 0.8 Gy; SD, 1.5 Gy; range, 0-4.8 Gy) in all patients. The mean (SD) breast dose for both breasts was 0.1 (0.2) Gy (left breast range, 0-1.0 Gy; right breast range, 0-0.9 Gy). Conclusions and Relevance: In this study, combined modality therapy with 2 cycles of ABVD and 20 Gy for ESFHL was highly effective and avoided excess doses to organs at risk, which may limit long-term toxic effects.

BACKGROUND: Nurses experience poor quality of life due to workload and role stress. In this study, a spirituality-based intervention was administered to nurse managers. METHOD: A total of 45 nurse managers participated in the study; 24 were assigned to the experimental group, and 21 were assigned to a control group. The Holy Name Meditation Program was provided solely to the experimental group. Pretest, posttest 1 (5 weeks after the intervention), posttest 2 (12 weeks after the intervention), and posttest 3 (24 weeks after the intervention) data were gathered on seven variables, including spiritual well-being, spiritual needs, job satisfaction, leadership, burnout, depression, and self-efficacy. RESULTS: The experimental group showed significant improvement in spiritual well-being (p < .001), spiritual needs (p = .029), and job satisfaction (p = .005) until the 24-week follow-up. Burnout (p < .001), depression and anxiety (p = .034), and self-efficacy (p = .024) showed significant improvement until the 12-week follow-up. Depression and anxiety (p = .053) showed decreasing tendency until the 24-week follow-up. CONCLUSION: Evidence suggests this program promotes spiritual and psychosocial well-being of nurse managers.

This study was conducted to evaluate the effects of the Holy Name Meditation on cancer patients' spiritual well-being, anxiety, depression, and pain. Twenty-eight patients were enrolled in the control group, and 18 patients were selected for the experimental group. Only the patients in the experimental group completed 5 weeks of the Holy Name Meditation Program. All participants were surveyed to assess spiritual well-being (Spiritual Well-Being Scale), anxiety and depression (Symptom Checklist 90-R), and pain (numeric pain rating scale). There were no significant differences between the two groups' general characteristics, but the baseline survey revealed that anxiety and depression levels were higher in the experimental group. Analyzing the results after controlling the baseline scores of anxiety and depression showed that spiritual well-being was increased (F = 4.80, P = .034), whereas anxiety (F = 4.98, P = .031) and depression (F = 7.28, P = .010) were decreased after the intervention. No difference in pain was found between the two groups. The Holy Name Meditation Program was thus effective in enhancing cancer patients' spiritual well-being and decreasing their anxiety and depression. Therefore, it is recommended that Holy Name Meditation be provided in clinical settings to reduce the psychosocial and spiritual suffering of cancer patients.

BACKGROUND: The aim was to investigate the efficacy of mechanical meibomian gland squeezing combined with eyelid scrubs and warm compresses in participants with moderate and severe meibomian gland dysfunction (MGD). METHODS: In this prospective, uncontrolled, open label, intervention study, 32 eyes of 32 participants with moderate and severe MGD were treated with mechanical squeezing of meibomian glands in combination with eyelid scrubs and warm compresses. We evaluated tear film break-up time (TBUT), corneal and conjunctival fluorescein staining scores, biomicroscopic examination of lid margins and meibomian glands, Ocular Surface Disease Index (OSDI) questionnaire and tear film lipid layer thickness determined via an interferometer before initiating treatment and after one month of treatment. RESULTS: There were significant improvements in TBUT, corneal and conjunctival fluorescein staining scores, lid margin abnormality, meibum quality and expressibility, OSDI and MGD stage after mechanical meibomian gland squeezing combined with eyelid scrubs and warm compresses (p < 0.001 for TBUT, corneal fluorescein staining scores, Dry Eye Workshop score, Oxford staining score, lid margin abnormality, meibum quality, expressibility, OSDI and MGD stage and p = 0.001 for conjunctival fluorescein staining scores). There were no significant differences in lipid layer thickness or interferometer-derived parameters before treatment and after one month of treatment. Palpebral conjunctival erosion detected after the squeezing treatment resolved spontaneously in all participants. CONCLUSIONS: Mechanical squeezing of meibomian glands combined with eyelid scrubs and warm compresses can provide clinical benefits without serious adverse events.

BACKGROUND: Several studies have suggested that low 25(OH) vitamin D3 levels may be prognostic in some malignancies, but no studies have evaluated their impact on treatment outcome in patients with acute myeloid leukemia (AML). METHODS: Vitamin D levels were evaluated in 97 consecutive, newly diagnosed, intensively treated patients with AML. MicroRNA expression profiles and single nucleotide polymorphisms (SNPs) in the 25(OH) vitamin D3 pathway genes were evaluated and correlated with 25(OH) vitamin D3 levels and treatment outcome. RESULTS: Thirty-four patients (35%) had normal 25(OH) vitamin D3 levels (32-100 ng/mL), 34 patients (35%) had insufficient levels (20-31.9 ng/mL), and 29 patients (30%) had deficient levels (<20 ng/mL). Insufficient/deficient 25(OH) vitamin D3 levels were associated with worse relapse-free survival (RFS) compared with normal vitamin D3 levels. In multivariate analyses, deficient 25(OH) vitamin D3 , smoking, European Leukemia Network genetic group, and white blood cell count retained their statistical significance for RFS. Several microRNAs and SNPs were associated with 25(OH) vitamin D3 levels, although none remained significant after multiple test corrections; one 25(OH) vitamin D3 receptor SNP, rs10783219, was associated with a lower complete remission rate (P = .0442) and with shorter RFS (P = .0058) and overall survival (P = .0011). CONCLUSIONS: It remains to be determined what role microRNA and SNP profiles play in contributing to low 25(OH) vitamin D3 level and/or outcome and whether supplementation will improve outcomes for patients with AML.

OBJECTIVE: To evaluate the effectiveness of scalp acupuncture (SA), a modern acupuncture technique specialized to neurological disorders, in managing motor function and symptoms for Parkinson's disease (PD) patients. METHODS: Two independent reviewers extracted data from all of the randomized clinical trials (RCTs) that assessed the efficacy of SA for PD compared with conventional therapies (CTs). Sixteen electronic databases were searched. The risk of bias was appraised with the Cochrane Collaboration tool, and the reporting of the included studies was evaluated by the Consolidated Standards of Reporting Trials (CONSORT) 2010 checklist and the revised Standards for Reporting Interventions in Clinical Trials of Acupuncture (STRICTA) guidelines. RESULTS: In total, 4 RCTs met the inclusion criteria. As assessed by the Unified PD Rating Scale (UPDRS), 2 RCTs showed that SA combined with CTs proved superior to CTs alone [60 cases; weighted mean difference, -3.94; 95% confidence interval (CI), -6.05 to -1.84, P=0.01; I(2) =0%]. Based on the Webster scale, however, 3 RCTs showed no superior effect of SA when combined with CTs with high heterogeneity (154 cases; risk ratio, 1.29; 95% CI, 0.79 to 2.12, P=0.30; I(2) =84%). The Cochrane risk of bias, adherence to the CONSORT and the STRICTA checklist showed that the quality of all the included RCTs was generally low. CONCLUSIONS: The result of our systematic review and meta-analysis suggested that the effectiveness of SA for PD is promising, however, the evidence is not convincing. A sham-controlled RCT design that adheres to the CONSORT and STRICTA guidelines to overcome methodological weakness and that includes a large sample size is strongly recommended to confirm the precise effect of SA on PD.

Background and Purpose. Traditional medicine (TM) has been widely used in China (including the Taiwan region), Korea, and Japan. The purposes of this paper are to summarize the basic data on TM systems in these three countries and to compare them in terms of overall policy, education, and insurance. Methods. Government websites, national statistics, and authoritative papers from each country were fully searched. Further data were gathered by TM experts from each country. Results. China and Korea showed similar patterns in TM systems, whereas Japan showed different patterns. In China and Korea, TM was practiced in a dual system with conventional medicine (CM), and TM education was 6-year training programs on average for TM doctors, and acupuncture, moxibustion, and cupping were completely insured. Whereas, CM was dominant in Japan, and TM was practiced by each health care worker who has received different TM education respectively, and main TM therapies were partially insured. Conclusions. TM was developed similarly or somewhat differently based on differences in cultural background and national policies in East Asia. We cautiously propose that this study could contribute to the development of TM and also be used for reference in complementary and alternative medicine systems.
RESUMEN
PURPOSE: To evaluate the safety and efficacy of fractional photothermolysis (FP) in the treatment of facial wrinkles in Asians. METHODS: A total of 27 Korean patients (Fitzpatrick type III or IV) received 2-3 FP treatment sessions (Sellas; Dinona Inc., Seoul, Korea) spaced two weeks apart. Treatments were performed at settings of 7 to 9 mJ/microthermal treatment zone (MTZ) and a density of 1000 MTZ/cm(2). Standardized digital photographs were obtained before each treatment and three months after the final treatment. The evaluations of clinical photographs were performed by three physicians blinded to the study subjects using a five-point grading scale. In addition, the patients' perceived degree of improvement was assessed three months after the final treatment using a five-point grading scale. Side effects were monitored at each follow-up visit. RESULTS: The physicians' assessed degrees of improvement were excellent in three patients (12%), significant in ten (40%), and moderate in seven (28%). The patients' self-assessed degrees of improvement were excellent in five patients (20%), significant in 11 (44%), and moderate in six (24%). Adverse events were limited to transient pain, erythema and edema, except in one case of transient postinflammatory hyperpigmentation. CONCLUSIONS: FP is an effective treatment modality for reducing facial wrinkles with minimal side effects in Asian patients.

This study is performed to detect changes of gene expression in substantia nigra (SN) and striatum in manganese (Mn)-exposed mice brain. The cDNA array is a recently developed molecular biological method that can detect the differential expression of several hundreds of genes simultaneously and is therefore advantageous in the study of trace metal intoxication effect at the genetic level. Using this technology, we discovered 5 genes in the mouse striatum and 9 genes in SN changed by more than 50% following Mn exposure. Depression were observed in two genes (neural cell adhesion protein BIG2, heavy neurofilament subunit genes) in striatum and three genes (light neurofilament subunit, brain acyl-CoA synthetase II, heavy neurofilament subunit genes) in the SN. However three genes (N-acetylglucosaminyltransferase I, S100beta, and synaptonemal complex protein I genes) in striatum and six genes (noggin, striatin, Ost oncogene, S100beta, calcium/calmodulin-dependent protein kinase kinase beta, and N-acetylglucosaminyltransferase I genes) in SN were elevated following Mn exposure. Immunohistochemical study revealed that protein levels of S100beta also increased following Mn treatment. Activated astrocytes overexpressing S100beta are invariably and intimately associated with decreased expression of heavy and light neurofilament subunits which is a distinguishing feature of neurodegeneration by Mn exposure. All our findings suggested that neuronal degenerations occur in SN as well as striatum of mice exposed to Mn.

A 25-year-old man, a field operator in a petroleum refinery was found unconscious. He was exposed to hydrogen sulfide and presented with Glasgow Coma Score of 5, severe hypoxemia on arterial blood gas analysis, normal chest radiography, and normal blood pressure. On hospital day 7, his mental state became clear, and neurologic examination showed quadriparesis, profound spasticity, increased tendon reflexes, abnormal Babinski response, and bradykinesia. He was also found to have decreased memory, attention deficits and blunted affect, which suggested general cognitive dysfunction, but which improved soon. MRI scan showed abnormal signals in both basal ganglia and motor cortex, compatible with clinical findings of motor dysfunction.

Characteristic high signal intensities confined to the globus pallidus on T1-weighted magnetic resonance image (MRI) can be observed in manganese (Mn)-exposed workers, however, these high signals should be differentiated from those due to other causes such as fat, hemoglobin breakdown products, melanoma, neurofibromatosis, and calcification. A 39-year-old woman was admitted with mutism and involuntary movements which had developed the day before. She had ingested two packs of liquid herbal medicine containing 0.53 mg of Mn daily for 4 months prior to visiting our hospital. Her MRI showed high signals, confined mainly to the globus pallidus on T1-weighted images. Follow-up brain MRI at an interval of 11 months showed no interval change. Brain computed tomography (CT) at the time of the second MRI showed symmetric calcification on both globus pallidus. Blood levels of liver function tests, calcium, phosphorus, and parathyroid hormone were within normal ranges. The increased signals, which were first presumed to be induced by Mn, were concluded to be due to calcification based on the following reasons. First, follow-up brain MRI at an interval of 11 months did not show any interval change. Second, the ingested amount of 1.06 mg Mn daily for 4 months is even less than that added to mineral supplements for adults. Third, Mn-induced high signals in T1-weighted MRI do not show any abnormal findings in brain CT. The present case report suggests that brain CT should be performed to rule out symmetric calcification on basal ganglia in patients showing increased signals in T1-weighted MRI, but who do not have a significant exposure history to Mn. The present report also showed that the amount of 1.06 mg Mn daily ingested for 4 months did not cause the high signal in brain MRI.
