We aimed to evaluate the safety and effectiveness of darunavir (DRV) in the treatment of human immunodeficiency virus-1 (HIV-1) infection in Korea. From October 29, 2010, 225 eligible patients with HIV-1 infection receiving DRV were enrolled. DRV was administered with other antiretroviral agents, and followed for 24 weeks. The primary objective was safety evaluation, and effectiveness was assessed by viral load and CD4 T cell counts after 12 weeks and 24 weeks. Adverse drug reactions occurred in 18 patients (9.2%); diarrhea was the most common. Viral load was controlled (<400 copies/mL) in 90.9% of patients. CD4 T cell counts were increased 45.0/mm3 significantly at Week 12 (P = 0.0002), and 70.5/mm3 at Week 24 (P <0.0001). DRV safety and effectiveness was consistent with previous studies.

PURPOSE: Cell transplantation of myelin-producing exogenous cells is being extensively explored as a means of remyelinating axons in X-linked adrenoleukodystrophy. We determined whether 3,3',5-Triiodo-L-thyronine (T3) overexpresses the ABCD2 gene in the polysialylated (PSA) form of neural cell adhesion molecule (NCAM)-positive cells and promotes cell proliferation and favors oligodendrocyte lineage differentiation. MATERIALS AND METHODS: PSA-NCAM+ cells from newborn Sprague-Dawley rats were grown for five days on uncoated dishes in defined medium with or without supplementation of basic fibroblast growth factor (bFGF) and/or T3. Then, PSA-NCAM+ spheres were prepared in single cells and transferred to polyornithine/fibronectin-coated glass coverslips for five days to determine the fate of the cells according to the supplementation of these molecules. T3 responsiveness of ABCD2 was analyzed using real-time quantitative polymerase chain reaction, the growth and fate of cells were determined using 5-bromo-2-deoxyuridine incorporation and immunocytochemistry, respectively. RESULTS: Results demonstrated that T3 induces overexpression of the ABCD2 gene in PSA-NCAM+ cells, and can enhance PSA-NCAM+ cell growth in the presence of bFGF, favoring an oligodendrocyte fate. CONCLUSION: These results may provide new insights into investigation of PSA-NCAM+ cells for therapeutic application to X-linked adrenoleukodystrophy.

PURPOSE: To evaluate the clinical features and treatment outcomes of smartphone overusers with acute acquired comitant esotropia. METHODS: We retrospectively reviewed the medical records of patients ≥ 15 years of age who used a smartphone for > 4 hours a day for > 1 year, and who were diagnosed with acute acquired comitant esotropia from May 2011 to January 2016. We analyzed sex, age at the time of manifestation and duration of esotropia, refractive error, deviated angle at the first and final visits, and the results of refraining from smartphone use, use of the Fresnel prism, and surgery for esotropia. RESULTS: A total of 13 patients were studied, including 8 males and 5 females. The mean age at development of esotropia was 22.7 ± 9.7 years. The mean duration of esotropia before the first visit was 28.0 ± 33.0 months, and the mean follow-up period was 16.4 ± 16.4 months. The mean angle of esotropia was 21.8 ± 7.0 prism diopters (PD) at distance and 22.2 ± 7.9 PD at near. There were eight myopic patients; the other patients were emmetropia. The esotropia of all patients did not improve after refraining from smartphone use. There was no improvement in five patients who were wearing the Fresnel prism for ≥ 4 months. A total of six patients were treated with bilateral medial rectus recession; only one patient remained orthotropic at postoperative 6 months, three patients were undercorrected, and two had a recurrence. CONCLUSIONS: Esotropia persisted after refraining from smartphone use or wearing a Fresnel prism in acute acquired comitant esotropia patients who were smartphone overusers, and the surgical prognosis of these patients was relatively poor.

Tumor necrosis factor alpha (TNFalpha) is a multifunctional inflammatory cytokine that regulates various cellular and biological processes. Increased levels of TNFalpha have been implicated in a number of human diseases including diabetes and arthritis. Sympathetic nervous system stimulation via the beta2-adrenergic receptor (beta2AR) in osteoblasts suppresses osteogenic activity. We previously reported that TNFalpha up-regulates beta2AR expression in murine osteoblastic cells and that this modulation is associated with TNFalpha inhibition of osteoblast differentiation. In our present study, we explored whether TNFalpha induces beta2AR expression in human osteoblasts and then identified the downstream signaling pathway. Our results indicated that beta2AR expression was increased in Saos-2 and C2C12 cells by TNFalpha treatment, and that this increase was blocked by the inhibition of NF-kappaB activation. Chromatin immunoprecipitation and luciferase reporter assay results indicated that NF-kappaB directly binds to its cognate elements on the beta2AR promoter and thereby stimulates beta2AR expression. These findings suggest that the activation of TNFalpha signaling in osteoblastic cells leads to an upregulation of beta2AR and also that TNFalpha induces beta2AR expression in an NF-kappaB-dependent manner.

BACKGROUND: Pregnancy considerably alters cardiovascular dynamics, and thereby affects the transition of blood pressure after delivery in women. We aimed to analyze the association between parity and blood pressure in Korean adult women. METHODS: We included 8,890 women who participated in Korean National Health and Nutrition Examination Survey between 2010 and 2012. We divided the population according to the menopause status and analyzed the association between parity and blood pressure by using multiple regression analysis, and on hypertension, by using logistic regression analysis. RESULTS: Systolic and diastolic blood pressures were significantly associated with parity in premenopausal women (beta=-0.091 [P<0.001] and beta=-0.069 [P<0.001], respectively). In the analysis that excluded women receiving antihypertensive medication, the systolic and diastolic blood pressure of postmenopausal women were significantly associated with parity (beta=-0.059 [P=0.022] and beta=-0.054 [P=0.044], respectively). Parity was found to prevent hypertension after adjustment for confounders in postmenopausal women (odds ratio, 0.55; 95% confidence interval, 0.310-0.985). CONCLUSION: We found that parity prevented hypertension in Korean women.

OBJECTIVE: To investigate the clinical characteristics, risk factors and complications of stroke patients and their effect on the patient's functional outcomes at discharge. METHOD: We performed a prospective study during hospitalization on 1, 250 consecutive acute stroke patients discharged from Dong-Eui Hospital from June 2001 to May 2002. Glasgow outcome scale, status of upper extremity involved and status of ambulation were used to evaluate functional status. RESULTS: The variables of clinical characteristics identified as significant in functional status at discharge were the presence of occupation, interval between onset and visit to hospital arrival, type of first treatment after stroke, type of caregiver, type of stroke and location of infarction and intracranial hemorrhage. Positive functional outcomes were significantly related to a younger age, male, small amount of hemorrhage and short length of hospital stay. Among risk factors of stroke, abnormal ECG findings at admission and presence of previous stroke were negative prognostic factors. The complications influencing stroke outcome negatively were pneumonia, depression, urinary tract infection, myocardial infarction and recurrence of stroke in hospitalization. CONCLUSION: The results of this study should be considered during acute management and rehabilitation of stroke patients and are valuable as basic data of functional outcome after stroke.

Background and Objectives:
The purpose of this study is to evaluate value of diagnostic tool for vocal cord palsy utilizing artificial intelligence without laryngoscopeMaterials and Method A dataset consisting of recordings from patients with unilateral vocal cord paralysis (n=54) as well as normal individuals (n=163). The dataset included prolonged pronunciations of the vowels /ah/, /u/, /i/, and vocal cord data from paralyzed patients. Various acoustic parameters such as Mel-frequency cepstral coefficients, jitter, shimmer, harmonics-to-noise ratio, and fundamental frequency statistics were analyzed. The classification of vocal cord paralysis encompassed paralysis status, paralysis degree, and paralysis location. The deep learning model employed the leave-one-out method, and the feature set with the highest performance was selected using the following methods.
Results:
Vocal Cord Paralysis Classifier: The classifier accurately distinguished normal voice from vocal cord paralysis, achieving an accuracy and F1 score of 1.0. Paralysis Location Classifier: The classifier accurately differentiated between median and paramedian vocal cord paralysis, achieving an accuracy and micro F1 score of 1.0. Breathiness Degree Classifier: The classifier achieved an accuracy of 0.795 and a mean absolute error of 0.2857 in distinguishing different degrees of breathiness.
Conclusion
Although the small sample size raises concerns of potential overfitting, this preliminary study highlights distinctive acoustic features in cases of unilateral vocal fold paralysis compared to those of normal individuals. These findings suggest the feasibility of determining the presence, degree, and location of paralysis through the utilization of acoustic parameters. Further research is warranted to validate and expand upon these results.

We investigated whether luteolin affects the gene expression, secretion and activity of matrix metalloproteinase-3 (MMP-3) in primary cultured rabbit articular chondrocytes, as well as production of MMP-3 in the rat knee to evaluate the potential chondroprotective effects of luteolin. Rabbit articular chondrocytes were cultured in a monolayer and IL-1beta-induced gene expression levels of MMP-3, MMP-1, MMP-13, a disintegrin and metalloproteinase with thrombospondin motifs-4 (ADAMTS-4), ADAMTS-5 and type II collagen were measured by reverse transcription - polymerase chain reaction (RT-PCR). Effects of luteolin on interleukin-1beta (IL-1beta)-induced secretion and enzyme activity of MMP-3 in rabbit articular chondrocytes were investigated by western blot analysis and casein zymography, respectively. The effect of luteolin on MMP-3 protein production was also examined in vivo. The results were as follows: (1) luteolin inhibited the gene expression levels of MMP-3, MMP-1, MMP-13, ADAMTS-4 and ADAMTS-5. However, it increased the gene expression level of collagen in rabbit articular chondrocytes; (2) luteolin inhibited the secretion and activity of MMP-3; (3) luteolin inhibited in vivo production of MMP-3 protein. These results suggest that luteolin can regulate the gene expression, secretion and activity of MMP-3, by directly acting on articular chondrocytes.
