Quality of Life Differences between Younger and Older Breast Cancer Patients

Purpose: This study was designed to investigate quality of life (QOL) differences between younger (<50 years) and older (≥50 years) breast cancer survivors and to determine the unique effect of age on QOL after adjusting age-correlated variables. Methods: One thousand two hundred fifty patients were enrolled. Clinicopatholgical and social parameters were reviewed and Functional Assessment of Cancer Therapy-Breast cancer instrument (FACT-B) and the Ladder of Life scale were used to measure the QOL. Among 1,250 eligible patients, 1,094 patients completed the questionnaire and were used for analysis. Chi-square test, t-test and a series of multiple regression analyses were conducted to verify age-related differences in QOL between two groups and to evaluate the unique contribution of age variable on QOL of breast cancer patients. Results: Significant socio-demographic and clinical differences existed based on age categories, includin

A systemic review and meta-analysis on the antihypertensive effect of aromatherapy essential oils

Purpose: This study is a systemic review of experimental results on the effects of aromatherapy on blood pressure. Materials and Methods: Journal articles published to December, 2017, were retrieved from twelve databases. Randomized controlled trials in which were evaluated for changes in blood pressure following aromatherapy were selected. Risks of bias were assessed using the risk-of-bias (ROB) tool of the Cochrane Collaboration. Meta-analysis were dine using RevMan. Results: Of the 2545 articles retrieved from the electronic databases, 580 duplicate articles and 1891 articles that were unrelated to the PICO (patient/problem, intervention, comparison, outcome) elements or did not satisfy the inclusion criteria excluded. Of the remaining 74 articles, 15 found to satisfy the inclusion criteria after full-text review and therefore selected for analysis. The findings of meta-analysis of 11 of these 15 articles revealed that essential oil inhalation and massage effectively decreased both systolic (n = 379; mean difference [MD], -4.72; 95% confidence interval [CI], -8.38 to -1.07) and diastolic (n = 379; MD, -2.42; 95% CI, -4.46 to -0.38) pressure. Conclusions: Essential oil inhalation and massage therapy can effectively decrease systolic and diastolic pressure in health adults as well as in patients with hypertension

Gastric Cancer Screening in Korea: Report on the National Cancer Screening Program in 2008

PURPOSE: The National Cancer Screening Program (NCSP) began in 1999. The objective of this report is to evaluate the results of the NCSP in 2008 and provide essential evidence associated with the gastric cancer screening program in Korea. MATERIALS AND METHODS: Data was obtained from the National Cancer Screening Information System; participation rates in gastric cancer screening were calculated. According to screening modalities, recall rates were estimated with 95% confidence intervals (CIs). RESULTS: The target population of the gastric cancer screening program in 2008 was 7,132,820 Korean men and women aged 40 and over, 2,076,544 of whom underwent upper endoscopy or upper gastrointestinal (UGI) series as screening tools (participation rate, 29.1%). Disparities in participation rates were observed relating to gender and health insurance type. Overall, recall rates of upper endoscopy and UGI series were 3.1% (95% CI, 3.0 to 3.1) and 33.3% (95% CI, 33.3 to 33.4), respectively. CONCLUSION: According to our research, efforts to facilitate participation and to reduce disparities in gastric cancer screening among Korean men and women are needed. These results will provide essential data for evidence-based strategies in gastric cancer control in Korea.ope

Prognostic value of low muscle mass at the 12th thoracic vertebral level in multiple myeloma treated with transplantation: CAREMM-2101 study

PURPOSEAutologous hematopoietic stem cell transplantation (ASCT) has been introduced as a standard treatment for newly diagnosed multiple myeloma (NDMM) following novel agent-based induction chemotherapy. This study investigated whether pre-ASCT low muscle mass evaluated using the paraspinal muscle index (PMI) at the 12th thoracic vertebra (T12) level is a reliable prognostic marker in NDMM after chemotherapy.METHODSA multi-center registry database was retrospectively analyzed. Between 2009 and 2020, 190 patients with chest computed tomography images underwent frontline ASCT following induction therapy. The PMI was defined as the value of the paraspinal muscle area at the T12 level divided by the square of the patient’s height. The cut-off value indicating a low muscle mass was sex-specific, using the lowest quintiles.RESULTSOf the 190 patients, 38 (20%) were in the low muscle mass group. The low muscle mass group had a lower 4-year overall survival (OS) rate than the non-low muscle mass group (68.5% vs. 81.2%; P = 0.074). The median progression-free survival (PFS) in the low muscle mass group was significantly shorter compared with the non-low muscle mass group (23.3 months vs. 29.2 months; P = 0.029). The cumulative incidence of transplant-related mortality (TRM) was significantly higher in the low muscle mass group than in the non-low muscle mass group (4-year probability of TRM incidence, 10.6% vs. 0.7%; P < 0.001). In contrast, no significant difference in the cumulative incidence of disease progression was found between the two groups. Multivariate analysis revealed that low muscle mass was associated with significant negative outcomes for OS [(hazard ratio (HR): 2.14; P = 0.047], PFS (HR: 1.78; P = 0.012), and TRM (HR: 12.05; P = 0.025).CONCLUSIONParaspinal muscle mass may have a prognostic role in NDMM patients who undergo ASCT. Patients with low paraspinal muscle mass have lower survival outcomes compared to non-low muscle mass group

PI3K-mTOR-S6K Signaling Mediates Neuronal Viability via Collapsin Response Mediator Protein-2 Expression

Collapsin response mediator protein (CRMP)-2 and the mammalian target of rapamycin complex 1 (mTORC1) signaling pathway are associated with common physiological functions such as neuronal polarity, axonal outgrowth and synaptic strength, as well as various brain disorders including epilepsy. But, their regulatory and functional links are unclear. Alterations in CRMP-2 expression that lead to its functional changes are implicated in brain disorders such as epilepsy. Here, we investigate whether changes in CRMP-2 expression, possibly regulated by mTOR-related signaling, correlates with neuronal growth and viability. Inhibition of mTOR and/or phosphoinositol-3-kinase (PI3K) led to deceased p-S6K, and p-S6 signals also reduced CRMP-2 expression. These changes corresponded to inhibition of neuronal viability and proliferation in cultured hippocampal HT-22 cells under both basal serum-free and serum- or insulin-induced mTOR pathway-activated conditions. CRMP-2 expression tended to be increased by mTOR activation, indicated by an increase in p-S6/S6 level, in pentylentetrazole (PTZ)-induced epileptic rat hippocampal tissues was also significantly reduced by mTOR inhibition. Knockdown of CRMP-2 by si-RNA reduced the neuronal viability without changes in mTOR signaling, and overexpression of CRMP-2 recovered the glutamate-induced neurotoxicity and decrease of mTOR signaling in HT-22 cells. In conclusion, CRMP-2 protein expression controlled by the PI3K-mTOR-S6K signaling axis exerts its important functional roles in neuronal growth and survival
