Purpose: This study aims to investigate and collect literature related to the effects of depression intervention programs on depression of breast cancer patients in Korea, and review these precedent studies on the effectiveness of depression intervention programs through meta-analysis. Methods: To achieve a systematic literature review, a review question was defined according to PICO-SD:“How do depression intervention programs affect depression reduction in breast cancer participants compared to the control group?” The subjects of this study were research papers on depression intervention programs, which were released in Korea between 1990 and February 2020. Through the literature quality assessment in accordance with the SIGN (2012) Guidelines on Quality Assessment, a total of 30 pieces were selected as the final subjects of this study. Result: The overall effect size of a total of 30 pieces was -3.92 (95% CI: -4.82, -3.03, p<.001), which indicates that these depression intervention programs have a great effect on depression reduction. Conclusion Intervention in depression of breast cancer patients in Korea is considered to contribute to improving the quality of their life and the ability to manage their symptoms, thus helping them have a positive meaning of life.

Purpose: The purpose of this study was to describe the health care experiences among patients with Parkinson’s disease. Methods: Of the qualitative research methods, Colaizzi’s phenomenological method was used in this study. A total of nine patients, who were diagnosed with Parkinson’s disease and receiving outpatient treatment, were selected as the subjects of this study. Subsequently, data were collected through individual in-depth interview. Results: The four categories obtained as a result were ‘strenuous efforts to control my own body,’ ‘subject of health that no one can replace,’ ‘focus on the current while expecting a breakthrough in health management,’ and ‘human dignity that cannot be lost to the end.’ Conclusion The study results are expected to help health care providers deeply understand the experiences in health care among patients with Parkinson’s disease and to provide source data for nursing intervention development that can be helpful in managing the health status of patients with Parkinson’s disease.

Essential thrombocythemia (ET) is characterized by most cases in which platelet counts exceed 1 million/µL. ET is usually no symptoms during non-pregnancy, but arterial and venous thrombosis and hemorrhage may develop in pregnancy. Pregnancy in these patients is associated with many complications in both pregnant women and fetuses such as recurrent abortion, intrauterine fetal growth restriction, preterm delivery, preeclampsia, and stillbirth. In these patients, aspirin, low-molecular-weight heparin (LMWH), and interferon alpha (INF-α) are recommended during pregnancy. We report a case of four consecutive abortions despite being treated with INF-α, low dose aspirin, and LMWH in patient with ET.

BACKGROUND: Follicular patterned thyroid nodules with incomplete nuclear features of papillary thyroid carcinoma (FTN-INPTCs) are difficult to diagnose, and their biological behavior and association with follicular variants of PTC (FVPTCs) have not yet been established. The aim of this study is to determine immunohistochemical and molecular characteristics of FTN-INPTCs. METHODS: We investigated immunohistochemical features (galectin-3, HBME-1, CK19, fibronectin-1, CITED1), BRAF V600E mutation and RASSF1A promoter methylation status in 30 FTN-INPTC cases, along with 26 FVPTCs, 21 follicular adenomas (FAs) and 14 nodular hyperplasias (NHs). RESULTS: Expression of galectin-3, HBME-1, CK19 and CITED1 was significantly higher in FTN-INPTCs than in FAs or NHs, but expression of galectin-3, CK19 and fibronectin-1 was lower in FTN-INPTCs than in FVPTCs. The BRAF V600E mutation was not detected in the benign nodules or FTN-INPTCs, whereas 57% of FVPTCs had the mutation. RASSF1A promoter methylation was higher in FTN-INPTCs than in benign nodules but there was no difference between FTN-INPTCs and FVPTCs. CONCLUSIONS: Our results represent the borderline immunohistochemical and molecular characteristics of FTN-INPTC. We conclude that FTN-INPTC is an intermediate lesion between a benign nodule and a FVPTC, and that it is pathogenetically related to FVPTC.

It has been previously demonstrated that dystrophin is cleaved in the cardiac myocyte by the viral protease 2A following infection with Coxsackievirus B3 (CVB3). The viral protease 2A mediated cardiomyopathy can be prevented by inhibiting cleavage of dystrophin. However, it is less clear whether uncleaved dysdrophin have other heart protective effect in coxsackievirus infection. To address this, we generated a Balb/C background mouse that had a point mutation in dystrophin that prevents cleavage by protease 2A (KI). We show here that when mice expressing cleavage-resistant dystrophin were infected with CVB3, there was increased cardiac myocyte apoptosis. Bax and Bcl-X(L) mRNA ratio was significantly increased in KI mice heart compare to wild type mice heart. We found cleavage-resistant dystrophin induced the apoptosis related enzyme capspase-3 and caspase-8 activity. In addition, TUNEL stain was observed many TUNEL positive cardiac myocyte in KI mice heart compare to wild type mice heart (3.7% vs 0.3%). However, zVAD treatment for apoptosis blocking was significantly decreased myocardium damage and fibrosis in KI mice heart. These findings indicated that uncleaved dystrophin may have a critical role in cardiac myocyte viral propagation. Uncleaved dystrophin mutant induced cardiac myocyte apoptosis. It delayed coxsackievirus propagation in cardiac myocyte and could prevent cardiac myocyte death.

Many in vivo and in vitro studies have demonstrated the targeted migration of neural stem cells (NSC) to infiltrating brain tumors, including malignant glioma, highlighting a potential therapeutic approach. However, there is not enough information to apply this approach to clinical therapy. The most important things in stem cell therapy for brain tumors involve selecting the appropriate neural progenitor type and optimizing the efficiency of the cell engraftment. By histological analysis using two different live-dyes, human NSCs were shown to migrate away from the transplanted site in the direction of the expanding C6 glioma and to intermix with the tumor bed, especially with the tumor core. This intermixing occurred within 7 days when NSCs were implanted into glioma model. The time course of migratory HB1.F5 with the greatest mobility of three NSC lines was as follows. As early as 3 days after transplantation, several NSCs were found leaving the implant site, primarily approaching microsatellites and frontier cells located near the site of NSC implantation. Through 7 days post-transplantation, massive numbers of NSCs continued to be attracted to and interspersed with C6 glioma, and were finally distributed extensively throughout the whole tumor bed, including the core and penumbra of the tumor mass. However, NSCs appeared to penetrate into the tumor mass very well, whereas normal fibroblast cells could not migrate. These findings strengthen the potential for human NSCs as attractive vehicles to improve therapeutic gene delivery to cancer or glioma if they are optimized to selectively kill neoplastic cells.

BACKGROUND: With the development of bioengineering techniques for noninvasive characterization of skin pathophysiology, the induction of irritant dermatitis by surfactants has been extensively studied. OBJECTIVE: We performed this study to compare the skin responses in terms of transepidermal water loss (TEWL) and erythema induced by benzalkonium chloride (BAC), a well-known non-corrosive irritant, in comparison with sodium lauryl sulfate (SLS), a representative corrosive irritant. METHOD: We applied 0.1, 0.2, 0.5, 1, and 2% solutions of BAC and SLS on volar forearm skin for 24 hours using a large Finn chamber with filter paper disc on 19 normal healthy subjects. TEWL and erythema index (E-index) were measured prior to testing, then at 30 minutes, one day, two days, three days, one week, and two weeks after the removal of the patches. RESULTS: TEWL values of BAC and SLS patch areas increased with concentration. However, BAC induced a significantly lower TEWL increase than SLS did at the corresponding concentrations. TEWL induced by BAC was highest at 30 minutes after the removal of the patch, whereas TEWL induced by SLS was highest at one day. TEWL values had recovered with the passage of time to baseline values at 2 weeks after removal of the patch at lower concentrations (0.1, 0.2, 0.5%) of SLS, but still showed significantly high TEWL values at 1% and 2% concentration SLS patch areas. TEWL values of BAC in 0.1, 0.2, 0.5 and 1% concentrations had recovered to the baseline values at 2 weeks after the removal of the patch, but not in 2% concentration BAC patch areas. E-indices of BAC and SLS increased with concentration in a similar reaction pattern. E-index induced by BAC was highest at 30 minutes after the removal of the patch, and E-index induced by SLS was highest at 30 minutes or 1 day after the removal of the patch. E-index of each concentration, except 2%, had recovered with the passage of time to baseline values on both BAC and SLS patch areas at 2 weeks, but E-indices of both 2% BAC and SLS did not recover at 2 weeks. CONCLUSION: Benzalkonium chloride showed much less damage to the skin barrier function compared to the corresponding concentration of SLS, whilst they showed a similar degree of erythema. Skin barrier function affected by the corrosive irritant SLS would need a more prolonged recovery time than skin barrier disruption by non-corrosive irritant BAC.

Recent evidence shows that transcriptional silencing as a consequence of hypermethylation of CpG islands is an important mechanism in the inactivation of p16INK4 tumor suppressor gene. This study is designed to clarify the significance of p16INK4 hypermethylation in 23 cases of glioblastomas (GBMs) by methylation-specific polymerase chain reaction (PCR) and p16 immunostaining. Fourteen cases (60.9%) out of 23 GBMs revealed hypermethylation on p16. p16 immunostaining revealed that 13 (93%) of these 14 hypermethylation cases showed complete loss of immunoreactivity and only one (7%) case retained immunoreactivity. Among 9 methylation-negative cases, 4 were immunonegative, which might be related to mutations or deletions other than hypermethylation. The most significant finding was that of 17 cases with immunonegativity, 13 cases (76.5%) showed hypermethylation. We reconfirmed that p16 hypermethylation may be one of the major mechanisms of tumorigenesis of GBMs and the results between the methylation specific-PCR study and p16 immunostaining had a good correlation.
