RESUMO
PURPOSE: We assessed the differences in chemotherapy-induced nausea and vomiting (CINV) severity in patients with breast cancer, receiving neoadjuvant chemotherapy (NAC) and adjuvant chemotherapy (AC). METHODS: CINV severity in patients on anthracycline-based NAC (n = 203) and AC (n = 79) was assessed at baseline (C0) and after the first and fourth chemotherapy using a 10-point Likert scale. Group-by-time interaction term was used to evaluate the effect of the group on changes in CIN (cCIN) and CIV (cCIV) from C0 to the follow-up periods (C1, C4). If insignificant, group effects were analyzed without the interaction term. Subgroup analysis was performed based on age 50. In statistical analyses, sociodemographic and clinical variables that differed between groups were adjusted for. RESULTS: The effect of group by follow-up period was not significant in cCIN and cCIV. The AC group showed a significantly higher change in the severity of cCIN compared to the NAC group (estimated mean = 1.133, 95% CI = 0.104-2.161, p = 0.031), but there was no difference in cCIV. In those ≤ 50 years, significant differences in cCIN severity (estimated mean = 1.294, 95% CI = 0.103-2.484, p = 0.033) were observed, but not in cCIV. In those > 50 years, neither cCIN nor cCIV differed significantly between groups. CONCLUSIONS: NAC in breast cancer patients showed less severe CIN than adjuvant chemotherapy AC, but not in those over 50. Clinicians should recognize that the severity of CIN may vary across different chemotherapy settings and adjust their management accordingly. TRIAL REGISTRATION: The clinical trial registration ( www. CLINICALTRIALS: gov ) numbers were NCT01887925 (the registration date is from June 20, 2013, to November 27, 2015) and NCT02011815 (the registration date is from December 10, 2013, to September 22, 2019).

OBJECTIVE: Patients with breast cancer receiving neoadjuvant chemotherapy are at increased risk of poor health-related quality of life (HRQOL). This study examined clinical caseness on depression and anxiety mediate the relationship between resilience and HRQOL in patients with breast cancer. METHODS: A total of 193 patients with breast cancer undergoing neoadjuvant chemotherapy completed questionnaires including the Connor-Davidson Resilience Scale, Hospital Anxiety and Depression Scale (HADS), and Functional Assessment of Cancer Therapy-Breast before the first session (T0), before the start of the last session (T1), and 6 months after the end (T2) of chemotherapy. Mediation analyses using a bootstrapping method was performed. RESULTS: The indirect effect (IE) through T1 depression was significant (IE through depression = 0.043, 95% confidence interval [CI] [0.002-0.090]), while IE through T1 anxiety was not significant (IE through anxiety = 0.037, 95% CI [-0.010-0.097]) in the association between T0 resilience and T2 HRQOL. CONCLUSIONS: Clinical caseness on HADS depression subscale during chemotherapy was a mediating factor of the relationship between resilience before chemotherapy and HRQOL after chemotherapy in patients with breast cancer receiving neoadjuvant chemotherapy. Depression during chemotherapy in patients with breast cancer may be a target symptom of screening and intervention to maintain the HRQOL after chemotherapy. Also, patients with low resilience are more likely to develop depression during chemotherapy, and clinicians should carefully monitor whether depression occurs in these patients with low resilience.

OBJECTIVE: This study aimed to develop and validate the Korean version of the Somatic Symptom Disorder-B Criteria Scale (SSD-12) in outpatients at a psychiatric clinic and assess its diagnostic accuracy. METHODS: A total of 207 patients completed SSD-12. For the diagnostic accuracy of SSD-12, the somatic symptom disorder (SSD) section of the structured clinical interview for DSM-5 disorders-research version (SCID-5-RV) was used. The SSD-12 construct and concurrent validity were assessed by examining the correlations with Generalized Anxiety Disorder-7 (GAD-7), Patient Health Questionnaire-9 (PHQ-9), PHQ-15, 5-level EQ-5D version (EQ-5D-5L), and World Health Organization Quality of Life Brief Version (WHOQOL-BREF). RESULTS: The SSD-12 had excellent internal consistency (Cronbach α=0.90). Confirmatory factor analysis revealed good fit indices for a general factor model (comparative fit index [CFI]=0.92, Tucker-Lewis index [TLI]=0.88, root mean square error of approximation [RMSEA]=0.10; 95% confidence interval [CI], 0.08-0.11) and a three-factor model (CFI=0.94, TLI=0.91, RMSEA=0.08; 95% CI, 0.07-0.10). The total SSD-12 score was significantly correlated with anxiety (GAD-7: r=0.53, p<0.001), depression (PHQ-9: r=0.52, p<0.001), physical symptom burden (PHQ-15: r=0.36, p<0.001), and quality of life (EQ-5D-5L: r=-0.40, p<0.001; WHOQOL-BREF: r=-0.51, p<0.001). SSD-12 demonstrated good accuracy (area under the curve=0.75, standard error=0.04; 95% CI, 0.68-0.82) with an optimal cut-off of 29. CONCLUSION: The Korean SSD-12 demonstrates reliability and validity for diagnosing SSD in clinical setting.
RESUMO
INTRODUCTION: The unalleviated burden of chronic physical illness (CPI) increases the risk of suicidal behaviors (SB) in affected individuals. This study tested the interpersonal theory of suicide (ITS) in patients with CPI. METHODS: Patients diagnosed with cardiovascular, cerebrovascular, and renal diseases were recruited from two hospitals in South Korea. Data from 257 participants who completed Time (T) 1 and T2 surveys were analyzed. Hierarchical regression analyses for passive and active suicide ideation (PSI and ASI), and suicide plans and attempts (SP and SA) at both time points were conducted. RESULTS: Interpersonal theory of suicide hypotheses were partially supported. Even accounting for factors such as depression, anxiety, and lifetime SA, some main and interaction effects of the ITS constructs explained SB in a cross-sectional examination, but to a lesser degree in a longitudinal examination that controlled for T1 SB. PB was a consistent correlate of SB. TB was also relevant, as PB-SA association was significant among participants with high TB both times. ASI was associated with SP and SA at T1, and the ASI-SP association at T1 was stronger at a high CS level. CONCLUSIONS: Overall, the results suggest the relevance of ITS constructs that warrant attention to prevent SB in patients with CPI.

OBJECTIVE: The object of this longitudinal cohort study was to investigate whether chronotype affects the incidence of chemotherapy-induced nausea and vomiting (CINV) among patients with breast cancer. METHODS: The study included a total of 203 breast cancer patients who received neoadjuvant chemotherapy using a regimen of doxorubicin and cyclophosphamide with high emetogenicity. Patients received four cycles of chemotherapy in approximately three months. Patients completed questionnaires including the Munich Chronotype Questionnaire (MCTQ) before the first chemotherapy and the Multinational Association of Supportive Care in Cancer Antiemesis Tool (MAT) after each of the four chemotherapy sessions. To confirm the effect of chronotype on CINV during the four cycles, we performed statistical analyses using a generalized estimating equation (GEE). RESULTS: CINV occurred in 108 (53.2%), 112 (55.2%), 102 (50.3%), and 62 (30.5%) patients during four cycles of treatment. In the GEE approach, late and early chronotypes (vs. intermediate chronotype) were associated with an increased risk of CINV (late chronotype: odds ratio [OR], 2.06; 95% confidence interval [CI], 1.41-2.99; p < 0.001, early chronotype: OR, 1.84; CI, 1.25-2.73; p = 0.002), which remained significant even after adjusting for age, BMI, antiemetic treatment, history of nausea and vomiting, anxiety, and sleep quality. CONCLUSION: Chronotype affected CINV across the four cycles of neoadjuvant chemotherapy in patients with breast cancer, suggesting the need to consider chronotype in predicting and managing CINV.
