Background: This study evaluated the safety and effectiveness of the cytomegalovirus (CMV) Specific Antigen Induced Interferon-Gamma ELISPOT (enzyme-linked immunosorbent spot)/ELISA (enzyme-linked immunosorbent assay) procedure in predicting the risk of CMV infection/disease in immunocompromised patients through a systematic literature review. Methods: The searched electronic databases included MEDLINE, EMBASE and the Cochrane Library. A total of 884 non-duplicate citations were retrieved and a total of 25 studies (15 cohort studies, 10 cross-sectional studies) were included in this review. Study subjects were selected among patients with solid organ, hematopoietic stem cell transplantation, or those who were on hemodialysis. Data extraction and literature quality assessment were carried out independently by two researchers. Results: Most of the studies were conducted on patients with solid organ transplants. As it is conducted outside the body, CMV Specific Antigen Induced Interferon-Gamma ELISPOT/ELISA assay was safe. Regarding its effectiveness, most studies on risk analysis based on prognosisrelated outcomes reported that the inactive group showed a significantly higher hazard ratio or odds ratio than the active group. Results of Kaplan-Meier survival analysis also showed that the inactive group had a significantly higher incidence of CMV event (CMV infection, CMV disease, other events) than the active group. However, various thresholds for CMV cell immune response were reported, as was a broad range of predictive diagnostic accuracies. Conclusion CMV Specific Antigen Induced Interferon-Gamma ELISPOT/ELISA assay has potential to stratify the risk of CMV infection/disease among solid organ transplant patients and to determine a policy for a prophylaxis/preemptive. However, additional literature evidence is needed to establish thresholds for CMV cell immune response and standardized tests.

Purpose: Fractional microneedle radiofrequency (FMR) systems are used to treat inflammatory acne and scarring. Nonetheless, few controlled studies have combined this treatment with the traditional ablative fractional laser (AFL). We aimed to assess the safety and efficacy of the combination of FMR and AFL versus AFL alone in treating acne and acne scars. Materials and Methods: In this 20-week, randomized, split-face study, 23 Korean patients with facial acne and acne scars underwent FMR and AFL treatments. One half of each patient’s face was randomly assigned to receive FMR+AFL, whereas the other half received AFL alone. Treatments were administered in three consecutive sessions at 4-week intervals. This study investigated the severity of inflammatory acne, acne scars, individual lesion counts, depressed scar volumes, as well as patient and physician satisfaction. In addition, five patients underwent skin biopsy, and sebum output was measured. Results: The FMR+AFL treatment demonstrated superior efficacy compared to AFL alone in terms of inflammatory acne and acne scar grading, lesion counts, and subjective satisfaction. The side effects were minimal and well-tolerated in both groups. Immunohistochemical findings from skin biopsy samples revealed that the application of FMR+AFL could induce an inhibitory effect on sebum secretion at the molecular level. Conclusion FMR combined with AFL is a well-tolerated and effective treatment modality for inflammatory acne and acne scarring.

BACKGROUND: Iron is essential for cell proliferation and viability. It has been reported that iron depletion by a chelator inhibits proliferation of some cancer cells. Deferasirox is a new oral iron chelator, and a few reports have described its effects on lymphoma cells. The goal of this study was to determine the anticancer effects of deferasirox in malignant lymphoma cell lines. METHODS: Three human malignant lymphoma cell lines (NCI H28:N78, Ramos, and Jiyoye) were treated with deferasirox at final concentrations of 20, 50, or 100 microM. Cell proliferation was evaluated by an MTT assay, and cell cycle and apoptosis were analyzed by flow cytometry. Western blot analysis was performed to determine the relative activity of various apoptotic pathways. The role of caspase in deferasirox-induced apoptosis was investigated using a luminescent assay. RESULTS: The MTT assay showed that deferasirox had dose-dependent cytotoxic effects on all 3 cell lines. Cell cycle analysis showed that the sub-G1 portion increased in all 3 cell lines as the concentration of deferasirox increased. Early apoptosis was also confirmed in the treated cells by Annexin V and PI staining. Western blotting showed an increase in the cleavage of PARP, caspase 3/7, and caspase 9 in deferasirox-treated groups. CONCLUSION: We demonstrated that deferasirox, a new oral iron-chelating agent, induced early apoptosis in human malignant lymphoma cells, and this apoptotic effect is dependent on the caspase-3/caspase-9 pathway.

OBJECTIVE: To evaluate whether smoking is a risk factor for female sexual dysfunction (FSD) and to determine the relationship between the cumulative smoking dose and FSD in premenopausal women. METHODS: The study population consisted of sexually active premenopausal women. The frequency of FSD and female sexual function index (FSFI) total score were evaluated according to the smoking status (never/former and current smokers). Evaluation of sexual function was done using FSFI questionnaire, and women with FSFI score of < or =26.55 were considered to have FSD. In current smokers, sexual function was also evaluated according to the cumulative smoking dose and nicotine dependency. RESULTS: A total of 900 women were included, and the frequency of current smokers and the frequency of FSD were 62 (6.9%) and 496 (55.1%), respectively. In current smokers, the frequency of FSD was significantly higher and the median total FSFI score was significantly lower than in never/former smokers, and this difference of FSD remained significant after adjustment for confounding variables. Among current smokers, the cumulative smoking dose (pack-years) and the total FSFI score showed negative correlation, in which increased cumulative smoking dose was associated with lower total FSFI score (r=-0.278, P<0.05). In terms of nicotine dependency, the total FSFI score of moderately to heavily nicotine dependent smokers was significantly lower than that of lightly dependent smokers. CONCLUSION: In premenopausal women, current smoking was an independent risk factor for FSD. And cumulative smoking dose and nicotine dependency were associated with higher risk of FSD.
