Effects of childhood experiences of parental attitude, depressive rumination, and sleep disturbances on adulthood depressive symptoms.

Aim: Various factors are thought to be involved in the development of depression, but the mechanisms are not yet clear. Although several reports have demonstrated that parental attitude experienced in childhood, depressive rumination, and sleep disturbances each influence depressive symptoms, and the association between two of these four variables, to our knowledge, no reports to date have investigated the association among the four variables. Methods: A questionnaire survey was administered to 576 adults who agreed to participate in this study between April 2017 and April 2018. Questionnaires assessed parental attitudes experienced in childhood, depressive rumination, sleep disturbances, and depressive symptoms in adulthood. The associations among the four variables were tested by structural equation modeling. Results: Regarding the direct effects, the parental attitude of "care" had a negative influence on depressive rumination and depressive symptoms, whereas "overprotection" had a positive influence on depressive rumination. Depressive rumination had a positive influence on sleep disturbance and depressive symptoms, whereas sleep disturbances had a positive influence on depressive symptoms. Regarding indirect effects, depressive rumination mediated the association between parental attitudes and sleep disturbances or depressive symptoms. Furthermore, sleep disturbances mediated the association between depressive rumination and depressive symptoms. Care and overprotection showed opposite effects. The goodness of fit of this model was high. Conclusion: The results of this study demonstrated that there were associations among the four variables. Clinical assessment and intervention of depressive rumination and sleep disturbances that are closely associated with previous parental attitudes may lead to an improvement of depressive symptoms.

Pembrolizumab-induced secondary adrenal insufficiency due to adrenocorticotrophic hormone deficiency in a patient with non-small-cell lung carcinoma: a case report.

BACKGROUND: Pembrolizumab can cause immune-related adverse events such as adrenal insufficiency (AI). However, there is no consensus regarding appropriate monitoring of adrenal function during subsequent chemotherapy in patients who have received immune checkpoint inhibitors (ICIs) such as pembrolizumab. CASE PRESENTATION: In this report, we discuss the case of a 60s-year-old male patient with non-small cell lung cancer receiving chemotherapy who developed secondary AI due to adrenocorticotrophic hormone (ACTH) deficiency 8 months after the discontinuation of pembrolizumab, which was 17 months after the initiation of pembrolizumab immunotherapy. After 5 months of chemotherapy, he developed fever and diarrhoea, after which chemotherapy was discontinued. Thereafter, he was hospitalised owing to the development of general fatigue and anorexia. Although cortisol and ACTH levels were not measured during chemotherapy, they were measured before hospitalisation, and secondary AI was suspected. After admission, a detailed endocrine workup was performed, and the patient was diagnosed with secondary AI due to ACTH deficiency. Treatment with hydrocortisone was initiated, which markedly improved his general fatigue and anorexia. The patient showed no evidence of progressive disease 9 months after the discontinuation of pembrolizumab. CONCLUSIONS: Although rare, the possibility of AI should be considered in patients who have received ICIs when nonspecific symptoms develop during or after subsequent chemotherapy, and measurements of endocrine function (including cortisol and ACTH levels) should be performed.

Pharmacovigilance study of the association between dipeptidyl peptidase-4 inhibitors and angioedema using the FDA Adverse Event Reporting System (FAERS).

Dipeptidyl peptidase-4 (DPP-4) plays a minor role in degrading vasoactive peptides that cause angioedema when angiotensin-converting enzyme (ACE) is present and fully functional. This study investigated the association between DPP-4 inhibitors (DPP-4Is) and angioedema, including cases where the concomitant use of ACE inhibitors (ACEIs) was absent. We obtained data from the US Food and Drug Administration Adverse Event Reporting System and performed a disproportionality analysis, using the reporting odds ratio (ROR) and information component (IC) for signal detection in patients aged ≥ 40 years, stratified by age group and sex. No signal was detected for DPP-4Is when the entire dataset was analyzed. However, a signal was detected for the entire female subset group, the three stratified female groups aged ≥ 60 years, and males in their 40 s. After excluding the data of concomitant ACEI users, most ROR and IC values were lower and significant only for females in their 60 s and males aged ≥ 80 years. Regarding individual DPP-4Is signals, those detected for saxagliptin and sitagliptin in some age groups disappeared after excluding the data of ACEI users. Notably, linagliptin was the only DPP-4I where signals were detected in most female groups, regardless of age and without concomitant ACEI use. Our findings suggest that some DPP-4Is were associated with a higher reporting of angioedema as per age and sex, even in the absence of concomitant ACEI use.

Influence of Cytochrome P450 2C19 Genotype on Helicobacter pylori Proton Pump Inhibitor-Amoxicillin-Clarithromycin Eradication Therapy: A Meta-Analysis.

Background: Proton pump inhibitors (PPIs) are the first-line treatment for acid-related diseases. The pharmacokinetics and therapeutic efficacy of PPIs, however, are influenced by genetic factors such as variants in genes encoding drug-metabolizing enzymes (e.g., cytochrome P450 2C19 [CYP2C19]) and drug transporters. We performed a meta-analysis to evaluate the influence of CYP2C19 genotype and PPI class, PPI dose, treatment duration and clarithromycin dose on the cure rate of PPI-containing Helicobacter pylori eradication therapy. Methods: Randomized control trials (RCTs) investigating cure rates using a PPI-amoxicillin-clarithromycin regimen among different CYP2C19 genotypes through May 2021 were included. Results: A total of 25 studies (5,318 patients) were included. The overall eradication rate in the intention-to-treat analysis was 79.0% (3,689/4,669, 95% confidence interval [CI]: 77.8-80.2%), and that in CYP2C19 extensive metabolizers (EMs), intermediate metabolizer (IMs) and poor metabolizers (PMs) was 77.7% (1,137/1,464, 95% CI: 75.3-79.6%), 81.2% (1,498/1,844, 95% CI: 79.3-83.0%) and 86.8% (644/742, 95% CI: 83.9-88.9%), respectively. Meta-analysis showed that the relaTakashitive risk of failed eradication in CYP2C19 EMs compared with IMs and PMs was 1.21 (95% CI: 1.06-1.39, P = 0.006) and 1.57 (95% CI: 1.27-1.94, P < 0.001), respectively, in the fixed-effects model. The cure rate of omeprazole and lansoprazole-containing eradication regimens differed among CYP2C19 genotypes (P < 0.05), while that of rabeprazole and esomeprazole-containing regimens was similar. Conclusion: The cure rates of PPI-amoxicillin-clarithromycin H. pylori eradication regimen, especially those containing omeprazole and lansoprazole, differ among CYP2C19 genotypes. Therefore, selection of a second-generation PPI or tailored treatment may achieve higher eradication rates than first-generation PPI-amoxicillin-clarithromycin triple regimen.

Development of Japanese Versions of the Control Preferences Scale and Information Needs Questionnaire: Role of Decision-Making and Information Needs for Japanese Breast Cancer Patients.

PURPOSE: The importance of shared decision-making (SDM) between physicians and patients is increasingly recognized. In Japan, patients have shown more willingness to participate in treatment if medical professionals provide sufficient information; however, relationships between physicians and patients have traditionally been asymmetric, with patients accepting information from physicians without discussion. To explore the benefits of SDM in cancer treatment, including confidence in treatment decisions, satisfaction with treatment, and trust in healthcare providers, this study developed Japanese versions of the Control Preference Scale (CPS) and Information Needs Questionnaire (INQ). PATIENTS AND METHODS: Reliability and validity of the CPS and INQ were tested with 49 breast cancer patients. RESULTS: The CPS showed good test-retest reliability (kappa coefficient: 0.61, weighted kappa coefficient: 0.61, Kendall's tau coefficient: 0.61) and acceptable criterion validity. The INQ showed adequate consistency; the mean number of circular triads and coefficient of consistency were 3 (range 0-19) and 0.9 (range 0.37-1), respectively. Using the CPS and INQ to identify patients' roles in decision-making and information needs, results further suggested that breast cancer patients in Japan want to participate in SDM. Medical issues, including disease spread and cure, were found to be of high interest, while social and psychological issues, including sexual attractiveness, genetic risk, and family impact, tended to be low. CONCLUSION: The Japanese CPS and INQ can be used to assess patients' needs to improve care. Further, as patients' information needs change along the care trajectory, these tools should be used throughout treatment.

Individual Lymphocyte Sensitivity to Steroids as a Reliable Biomarker for Clinical Outcome after Steroid Withdrawal in Japanese Renal Transplantation.

Recently, steroid reduction/withdrawal regimens have been attempted to minimize the side effects of steroids in renal transplantation. However, some recipients have experienced an increase/resumption of steroid administrations and acute graft rejection (AR). Therefore, we investigated the relationship between the individual lymphocyte sensitivity to steroids and the clinical outcome after steroid reduction/withdrawal. We cultured peripheral blood mononuclear cells (PBMCs) isolated from 24 recipients with concanavalin A (Con A) in the presence of methylprednisolone (MPSL) or cortisol (COR) for four days, and the 50% of PBMC proliferation (IC50) values and the PBMC sensitivity to steroids were calculated. Regarding the experience of steroid increase/resumption and incidence of AR within one year of steroid reduction/withdrawal, the IC50 values of these drugs before transplantation in the clinical event group were significantly higher than those in the event-free group. The cumulative incidence of steroid increase/resumption and AR in the PBMC high-sensitivity groups to these drugs before transplantation were significantly lower than those in the low-sensitivity groups. These observations suggested that an individual's lymphocyte sensitivity to steroids could be a reliable biomarker to predict the clinical outcome after steroid reduction/withdrawal and to select the patients whose dose of steroids can be decreased and/or withdrawn after transplantation.

Pharmacodynamic Drug-Drug Interaction on Human Peripheral Blood Mononuclear Cells Between Everolimus and Tacrolimus at the Therapeutic Concentration Range in Renal Transplantation.

BACKGROUND Everolimus (EVL) plus tacrolimus (TAC) therapy is effective and safe in renal transplantation. However, the pharmacokinetic and pharmacodynamic information for EVL combined with TAC is limited. We investigated the pharmacodynamic drug-drug interaction between EVL and TAC at their therapeutic concentration range. MATERIAL AND METHODS Isolated peripheral blood mononuclear cells (PBMCs) from 22 healthy participants aged 22 to 24 years were cultured with concanavalin A (Con A) in the presence of EVL and/or TAC for 4 days, and the proliferation rate of the PBMCs was calculated. RESULTS TAC promoted the inhibitory efficacy of EVL against the mitogen-activated proliferation of PBMCs at the EVL therapeutic concentration range. When 0.175 ng/mL or more of TAC was combined with 30 ng/mL or more of EVL, the antagonistic effect of TAC on the inhibitory efficacy of EVL against the mitogen-activated proliferation of PBMCs was observed. Conversely, when 0.4 ng/mL TAC and 10 ng/mL or more of EVL were combined, the antagonistic effect of EVL on the inhibitory efficacy of TAC against the mitogen-activated proliferation of PBMCs was observed. CONCLUSIONS The pharmacodynamic synergistic efficacy of EVL and TAC in combination on mitogen-activated PBMCs was evident at the therapeutic concentration range, which is used in renal transplantation. However, these drugs antagonize each other to suppress the proliferation of activated PBMCs at concentrations higher than those clinically used.

Solvent-Dependent Mechanism and Stereochemistry of Mitsunobu Glycosylation with Unprotected Pyranoses.

An SN2 mechanism was proposed for highly stereoselective glycosylation of benzoic acid with unprotected α-d-glucose under Mitsunobu conditions in dioxane, while an SN1 mechanism was indicated for nonstereoselective glycosylation in DMF. The SN2-type stereoselective Mitsunobu glycosylation is generally applicable to various unprotected pyranoses as glycosyl donors in combination with a wide range of acidic glycosyl acceptors such as carboxylic acids, phenols, and imides, retaining its high stereoselectivity (33 examples). Glycosylation of a carboxylic acid with unprotected α-d-mannose proceeded also in an SN2 manner to directly afford a usually less accessible 1,2-cis-mannoside. One- or two-step total syntheses of five simple natural glycosides were performed using the glycosylation strategy presented here using unprotected α-d-glucose.

Total Synthesis of Ellagitannins via Sequential Site-Selective Functionalization of Unprotected D-Glucose.

A short-step total synthesis of the natural glycosides pterocarinin C and tellimagrandin II (eugeniin) has been performed by sequential and site-selective functionalization of free hydroxy groups of unprotected D-glucose. The key reactions are ß-selective glycosidation of a gallic acid derivative using unprotected D-glucose as a glycosyl donor and catalyst-controlled site-selective introduction of a galloyl group into the inherently less reactive hydroxy group of the glucoside.

Fabrication of White Light-emitting Electrochemical Cells with Stable Emission from Exciplexes.

The authors present an approach for fabricating stable white light emission from polymer light-emitting electrochemical cells (PLECs) having an active layer which consists of blue-fluorescent poly(9,9-di-n-dodecylfluorenyl-2,7-diyl) (PFD) and π-conjugated triphenylamine molecules. This white light emission originates from exciplexes formed between PFD and amines in electronically excited states. A device containing PFD, 4,4',4''-tris[2-naphthyl(phenyl)amino]triphenylamine (2-TNATA), Poly(ethylene oxide) and K2CF3SO3 showed white light emission with Commission internationale de l'éclairage (CIE) coordinates of (0.33, 0.43) and a Color Rendering Index (CRI) of Ra = 73 at an applied voltage of 3.5 V. Constant voltage measurements showed that the CIE coordinates of (0.27, 0.37), Ra of 67, and the emission color observed immediately after application of a voltage of 5 V were nearly unchanged and stable after 300 sec.

A Concise Access to C2-Symmetric Chiral 4-Pyrrolidinopyridine Catalysts with Dual Functional Side Chains.

A practical method was developed for the preparation of a diastereomeric library of C2-symmetric chiral 4-pyrrolidinopyridine catalysts with dual amide side chains. Use of a racemic precursor is the key to the concise production of catalysts with diverse stereochemisty.

Total Synthesis of Ellagitannins through Regioselective Sequential Functionalization of Unprotected Glucose.

Short total syntheses of natural glycosides (ellagitannins) were performed through sequential and regioselective functionalization of the hydroxy groups of unprotected glucose. The key reactions are ß-selective glycosidation of a gallic acid derivative by using unprotected glucose as a glycosyl donor and catalyst-controlled regioselective introduction of a galloyl group into the inherently less reactive hydroxy group of the glucoside.

Stereocontrolled synthesis of vicinally functionalized piperidines by nucleophilic ß-addition of alkyllithiums to α-aryl substituted piperidine enecarbamates.

Substituted piperidines are emerging as important medicinally-active structural motifs. Here, we report highly stereoselective carbolithiation reactions of α-aryl piperidine enecarbamates that offer direct access to vicinally-substituted piperidine compounds. We have also demonstrated that the carbanion intermediates can be trapped with a carbon electrophile.

Clinical Significance of Female-hormones and Cytokines in Breast Cancer Patients Complicated with Aromatase Inhibitor-related Osteoarthropathy - Efficacy of Vitamin E.

INTRODUCTION: Aromatase inhibitor use for postmenopausal hormone-sensitive breast cancer patients often results in drug-induced osteoarthropathy, while its accurate mechanism has not been clarified. We investigated the implication of female hormones and several cytokines in osteoarthropathy complicated with aromatase inhibitor treatment, and the efficacy of vitamin E on the severity of osteoarthropathy, in breast cancer patients. METHODS: Sixty two breast cancer patients treated with aromatase inhibitor for average of 1.77 years were included. These patients were orally administered vitamin E (150mg/day) for 29.8 days to alleviate aromatase inhibitor-related osteoarthropathy. Severity of osteoarthropathy was scored, and the patients were grouped based on the severity or vitamin E efficacy. Serum estradiol, progesterone, vitamin E, interferon-gamma (IFN-gamma), tumor necrosis factor-alpha (TNF-alpha), IL-2, IL-4, IL-6, IL-10, and IL-17A concentrations were measured by ELISA or beads array procedures followed by flow cytometry. RESULTS: There was no significant difference in serum concentrations of the biomarkers between the severe and the mild osteoarthropathy groups before vitamin E administration. The osteoarthropathy scores significantly decreased after vitamin E administration (p=0.0243), while serum-estradiol concentrations did not change. The serum-estradiol concentrations before vitamin E administration in the group sensitive to the vitamin E efficacy were significantly lower, as compared with those in the insensitive group (p=0.0005). The rate of the highly sensitive patients to the vitamin E efficacy in those exhibiting low serum-estradiol concentrations was significantly higher than that in the high serum-estradiol group (p=0.0004). In the sensitive group, serum-estradiol concentrations after taking vitamin E were significantly higher than those before taking vitamin E (p=0.0124). CONCLUSIONS: Vitamin E administration seemed to be a potential way for relieving osteoarthropathy complicated with aromatase inhibitor use. Using serum-estradiol concentration, it would be possible to select out the breast cancer patients who will respond well to the vitamin E therapy for osteoarthropathy complicated with aromatase inhibitor.

Synergistic Effects of Calcineurin Inhibitors and Steroids on Steroid Sensitivity of Peripheral Blood Mononuclear Cells.

The steroid receptor (SR) complex contains FKBP51 and FKBP52, which bind to tacrolimus (TAC) and cyclophilin 40, which, in turn, bind to cyclosporine (CYA); these influence the intranuclear mobility of steroid-SR complexes. Pharmacodynamic interactions are thought to exist between steroids and calcineurin inhibitors (CNIs) on the SR complex. We examined the effect of CNIs on steroid sensitivity. Methylprednisolone (MPSL) sensitivity was estimated as the concentration inhibiting mitosis in 50% (IC50) of peripheral blood mononuclear cells and as the area under the MPSL concentration-proliferation suppressive rate curves (CPS-AUC) in 30 healthy subjects. MPSL sensitivity was compared between the additive group (AG) as the MPSL sensitivity that was a result of addition of the proliferation suppressive rate of CNIs to that of MPSL and the mixed culture group (MCG) as MPSL sensitivity of mixed culture with both MPSL and CNIs in identical patients. IC50 values of MPSL and cortisol sensitivity were examined before and 2 months after CNI administration in 23 renal transplant recipients. IC50 and CPS-AUC values of MPSL were lower in the MCG than in the AG with administration of TAC and CYA. The CPS-AUC ratio of MCG and AG was lower in the TAC group. IC50 values of MPSL and cortisol tended to be lower after administration of TAC and CYA, and a significant difference was observed in the IC50 of cortisol after TAC administration. Steroid sensitivity increased with both TAC and CYA. Furthermore, TAC had a greater effect on increasing sensitivity. Thus, concomitant administration of CNIs and steroids can increase steroid sensitivity.

Preferences for pharmacist counselling in patients with breast cancer: a discrete choice experiment.

With the shift of a large proportion of cancer chemotherapy recipients to ambulatory care, the role of hospital pharmacists has changed, and their provision of information is essential care for cancer patients. There is little research on pharmacist-patient relations, particularly about pharmacist counselling, in Japan. To meet patients' needs, pharmacist counselling should be optimized. Here, breast cancer patients' preferences for pharmacist counselling were assessed using a discrete choice experiment. Bayesian nonlinear optimal methodology was employed to obtain six attributes (attitude of pharmacist, quality of information, explanation of side effects, frequency of pharmacist counselling before starting chemotherapy, cost of pharmacist counselling, and follow-up with the pharmacist after starting chemotherapy) of two to three levels each. The attributes and levels were used to create 12 hypothetical scenarios that were divided into two questionnaires of six choice sets each. Two hundred eighty participants were randomly assigned to complete one of these questionnaires (blocks). Attributes were analyzed by conditional logit model to determine significant predictors of patient preferences. The responses of 278 patients to 1667 scenarios were analyzed. Attitude of pharmacist, quality of information, cost of pharmacist counselling, and follow-up with the pharmacist after starting chemotherapy were significant predictors of patient preferences, with quality of information receiving the highest priority. Thus patients receiving pharmacist counselling before starting chemotherapy prefer to interact with a pharmacist with a friendly, interested attitude who provides individualized information. Further research is needed to elucidate the information that Japanese patients consider most important and to enhance pharmacist-patient communication.

Clinical significance of peripheral blood lymphocyte sensitivity to glucocorticoids for the differentiation of high-risk patients with decreased allograft function after glucocorticoid withdrawal in renal transplantation.

PURPOSE: A reliable biomarker to differentiate high-risk recipients who will experience a decrease in allograft function after glucocorticoid withdrawal has not been established in renal transplantation. We examined the clinical significance of peripheral blood lymphocyte sensitivity to glucocorticoids in vitro for the differentiation of the high-risk patients after glucocorticoid reduction/withdrawal in renal transplant recipients. METHODS: The study included 44 renal transplant recipients with stable allograft function. Peripheral lymphocyte responses to suppressive effects of cortisol, methylprednisolone, cyclosporine, and tacrolimus in mitogen assay procedures in vitro were examined. Clinical outcome after glucocorticoid reduction/withdrawal was retrospectively compared between recipients with lymphocytes normally sensitive to the drugs and those with hyposensitivity. The receiver-operating characteristic (ROC) curve analysis was undertaken for setting the cutoff IC50 values of the drugs against the T cell mitogen-induced lymphocyte proliferation to differentiate the high-risk recipients with decreased allograft function after glucocorticoid withdrawal. FINDINGS: The median (range) IC50 value for cortisol in the recipients who showed decreased renal function due to glucocorticoid withdrawal was 10,000 (570.9-72,279.3) ng/mL (n = 9), which was significantly higher than the value of 351.6 (2.0-10,000) ng/mL in the recipients who had not experienced glucocorticoid withdrawal symptoms (n = 35) (P < 0.001). Similarly, the median (range) IC50 value for methylprednisolone in the recipients who showed decreased renal function after glucocorticoid withdrawal was 69.1 (21.5-1442.7) ng/mL (n = 9), which was significantly higher than the value of 13.8 (0.7-1000) ng/mL in the recipients who had not experienced glucocorticoid withdrawal symptoms (n = 30) (P < 0.003). In contrast, there was no significant difference in the median IC50 values of cyclosporine and tacrolimus between the 2 recipient subgroups. The ROC curve analyses for the IC50 values of the immunosuppressive drugs estimated the cutoff value of cortisol and methylprednisolone to be 3580.0 and 21.5 ng/mL, respectively. The ROC AUCs for cortisol and methylprednisolone were 0.83 and 0.84, respectively. According to the cutoff IC50 value, the incidence of decreased allograft function in the low cortisol sensitivity (IC50 >3580.0 ng/mL) subgroup was 7 of 13 patients, which was significantly higher than that of the higher sensitivity subgroup of 2 of 31 (P = 0.0012). A similar case was observed using the cutoff IC50 value of methylprednisolone (P = 0.0012), whereas recipient grouping according to the cutoff IC50 values of cyclosporine and tacrolimus failed to differentiate the high-risk recipients with decreased allograft function after glucocorticoid withdrawal. IMPLICATIONS: Glucocorticoid pharmacodynamics in lymphocytes of individual patient origin is a reliable biomarker for differentiation of renal transplant recipients who will experience a safe reduction/withdrawal of glucocorticoid.

Development and validation of the Japanese version of the Decisional Conflict Scale to investigate the value of pharmacists' information: a before and after study.

BACKGROUND: The information provided in patient-centered care and shared decision-making influences patients' concerns and adherence to treatment. In the decision-making process, patients experience decisional conflict. The Decisional Conflict Scale (DCS) is a 16-item, self-administered questionnaire consisting of 5 subscales developed to assess patients' decisional conflict. This study aimed to develop the Japanese version of the DCS and to clarify the influence of the information provided by pharmacists' on decisional conflict among patients with cancer. METHODS: We developed the Japanese version of the DCS by using the forward-backward translation method. One hundred patients who were recommended a new chemotherapy regimen were recruited. The psychometric properties of the Japanese DCS, including internal consistency, convergent validity, discriminant validity, and construct validity, were examined. We assessed the decisional conflict of patients before and after the pharmacists' provision of information. RESULTS: Ninety-four patients, predominately female, with an average age of 58.1 years were sampled. The scores on the 5 subscales of the DCS showed high internal consistency (Cronbach's alpha = 0.84-0.96). Multi-trait scaling analysis and cluster analysis showed strong validity. The mean total DCS score decreased significantly from 40.2 to 31.7 after patients received information from the pharmacists (p < 0.001, paired t-test). Scores on all 5 subscales, namely, uncertainty, informed, values clarity, support, and effective decision, also significantly improved (p < 0.001 for all categories, paired t-test). CONCLUSIONS: The psychometric properties of the Japanese version of the DCS are considered appropriate for it to be administered to patients with cancer. Pharmacists' provision of information was able to decrease decisional conflict among patients with cancer who were recommended a new chemotherapy regimen.

Determinants affecting quality of life: implications for pharmacist counseling for patients with breast cancer in Japan.

Although pharmacist counseling assumes an important role in the clinical setting, oncology pharmacy practitioners worldwide currently lack adequate guidance. This study aimed to identify the determinants and causal relationships that affect quality of life (QOL) in breast cancer patients before adjuvant systemic therapy for improving pharmacist counseling and guidance. This study analyzed 93 postoperative patients with breast cancer before pharmacist counseling for adjuvant systemic therapy. Patients were asked to complete questionnaires to assess QOL (the European Organisation for Research and Treatment of Cancer Quality of Life Questionnaire C30 [EORTC QLQ-C30] and its breast cancer module [EORTC QLQ-BR23]) before pharmacist counseling. We analyzed factors affecting QOL by stepwise multiple linear regression analysis and evaluated causal association using path analysis. In the multiple linear regression model using variables selected by stepwise analysis, the factors affecting global health status (GHS)/QOL included fatigue, emotional functioning, systemic therapy side effects, future perspectives, and appetite loss. In the path analysis model, GHS/QOL were strongly influenced by fatigue directly; and emotional functioning, directly and indirectly via other factors. Our results indicated that fatigue and emotional functioning are strong factors affecting QOL. These factors may be able to predict poor QOL before initiating adjuvant systemic therapy. Thus, our findings suggest that these factors may be potentially useful for pharmacist counseling at the beginning of adjuvant systemic therapy.

Higher Sensitivity of Peripheral Blood Lymphocytes to Endogenous Glucocorticoid in Renal Transplant Recipients Treated With Tacrolimus, as Compared to Those Treated With Cyclosporine.

Lymphocyte sensitivity to endogenous glucocorticoid cortisol could be a biological marker for safe reduction and withdrawal of steroids in renal transplant recipients. We compared peripheral lymphocyte sensitivity with cortisol between transplant recipients treated with tacrolimus (Tac) and those treated with cyclosporine. The suppressive efficacies of cortisol against T-cell mitogen-stimulated proliferation of peripheral lymphocytes were investigated in 44 renal transplant patients, who either had reduced or been withdrawn from steroid treatment. Twenty of the 44 patients were treated with Tac, and the other 24 patients were treated with cyclosporine A (CyA). The lymphocyte sensitivity to cortisol was compared between these two patient groups. The cortisol IC50 values in the Tac and CyA groups were 0.09 ± 0.12 and 14.2 ± 12.7 ng/ml, respectively. Lymphocyte sensitivity to cortisol in the Tac-treated group was significantly higher than that in the CyA-treated group (p = 0.0283). On the other hand, incidences of steroid withdrawal syndrome and increases in serum creatinine concentration were not significantly different between the Tac and CyA groups. Lymphocyte sensitivity to cortisol was higher in the Tac-treated patients than that in the CyA-treated ones. Since the cortisol sensitivity of peripheral lymphocytes is suggested to be a predictive marker for safe steroid withdrawal, Tac administration shows promise in aiding successful withdrawal of steroid treatment in long-term renal transplant recipients.
