Abstract 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.

Abstract 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.

Abstract 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.

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.
