Previous studies have shown that bipolar disorder (BD) patients frequently present with difficulties in interpersonal relationships, education or employment and suffer poorer quality of life. This study aimed to estimate the impact of BD on health-related quality of life (HRQOL), work productivity loss and indirect costs.
Data was from the online, self-administered 2019 National Health and Wellness Survey. Outcomes were compared for those who self-reported a physician diagnosis of BD (N=179), major depressive disorder (MDD, N=1,549) and controls who have never experienced BD, MDD and schizophrenia (N=27,485).
The lifetime prevalence was estimated to be 0.60% for BD and 5.16% for MDD. Significantly lower Mental Component Summary (MCS), Role Component Summary (RCS) scores and EuroQol 5-dimension scale (EQ-5D-5L) summary index and significantly higher presenteeism, total work productivity impairment and activity impairment assessed by Work Productivity and Activity Impairment questionnaire and indirect costs for BD versus controls and BD PHQ-9≥10 versus PHQ-9<10 were observed. Compared to MDD patients, BD patients had significantly lower RCS score and greater work productivity loss and activity impairment. The national morbidity cost of BD in Japan was estimated to be Japanese yen 1,236 billion using a human-capital approach.
The data used were self-reported and is cross-sectional in nature, thus causal relationship cannot be assumed.
BD patients and those with severe depressive symptoms experience significantly poorer HRQOL and greater work productivity loss and indirect costs. These findings highlight the importance of proper screening, diagnosis and treatment of BD and bipolar depression.

Cellular senescence is an inherent tumor suppressive process, and cancer-targeted senescence induction represents an attractive anti-tumor strategy. Here, we show that a methoxyflavanone derivative ...(Perilla-derived methoxyflavanone, PDMF) from the Asian medicinal herb, Perilla frutescens, induces cellular senescence in A549 human adenocarcinoma cells but not in normal human bronchial epithelial (NHBE) cells. We also provide evidence that PDMF preferentially activates the p53–p21 pathway in A549 cells, and that p53 is essential for its pro-senescent activity.
Background and Aim
The impact of chronic constipation on health‐related quality of life (HRQoL), work productivity, and healthcare resource use in Japan is not well understood. This study aimed to ...evaluate and compare the humanistic burden of respondents with chronic constipation to respondents without chronic constipation and to respondents with type 2 diabetes mellitus (T2DM), irritable bowel syndrome (IBS), and gastroesophageal reflux disease (GERD), respectively.
Methods
This cross‐sectional study collected demographic and general health data and HRQoL data as measured by the Short Form 12‐Item (Version 2) Health Survey and EuroQol 5‐dimension health surveys. Health impacts on employment‐related activities and indirect costs were measured using the Work Productivity and Activity Impairment questionnaire. Propensity score matching was used to identify a control group without chronic constipation. Multivariate generalized linear models were used to identify potential factors that may impact the outcomes of respondents.
Results
A total of 30 001 individuals responded to the Japan National Health and Wellness Survey 2017, whereof 3373 (11.2%) reported having chronic constipation; 963 were physician diagnosed. Compared with matched controls, patients with physician‐diagnosed chronic constipation had lower mean HRQoL scores and higher mean absenteeism, presenteeism, total Work Productivity and Activity Impairment, and indirect costs. Physician‐diagnosed chronic constipation was associated with a higher health burden than T2DM, IBS, and GERD.
Conclusions
Chronic constipation is associated with a considerable health burden, which is higher compared with T2DM, IBS, and GERD. These results suggest an urgent need for effective treatment of Japanese patients with chronic constipation to improve their quality of life.

Lymphoma is the most common hematological cancer in dogs. Canine diffuse large B cell lymphoma shows a relatively good response to treatment with multi-agent cyclophosphamide, doxorubicin, ...vincristine, and prednisone (CHOP) chemotherapy; however, the 2-year survival rate is as low as 20%. For human B cell type lymphoma, the anti-CD20 chimeric antibody, rituximab, was developed two decades ago. The combination of rituximab and CHOP chemotherapy was highly successful in improving patient prognosis. However, no anti-canine CD20 antibody is available for the treatment of canine lymphoma. During this study, a rat anti-canine CD20 monoclonal antibody was established. We also generated a rat-canine chimeric antibody against canine CD20 designed for clinical application. This chimeric antibody (4E1-7-B) showed in vitro antibody-dependent cell-mediated cytotoxicity (ADCC) and complement-dependent cytotoxicity (CDC) against the canine B cell lymphoma cell line CLBL-1. Moreover, to obtain stronger ADCC activity, a defucosylated 4E1-7-B antibody (4E1-7-B_f) was also generated, and it showed tenfold stronger ADCC activity compared with 4E1-7-B. 4E1-7-B_f as well as 4E1-7-B suppressed the growth of CLBL-1 tumors in an immunodeficient xenotransplant mouse model. Finally, a single administration of 4E1-7-B_f induced considerable peripheral B cell depletion in healthy beagles. Thus, 4E1-7-B_f is a good antibody drug candidate for canine B cell type lymphoma.

Abstract
Background
Schizophrenia places a great humanistic and financial burden to patients, families, and societies, and the burden is substantially impacted by comorbid conditions. This study ...aimed to estimate the lifetime prevalence of schizophrenia and to assess the health-related quality of life (HRQoL), work productivity, and indirect cost among schizophrenia patients with and without comorbidities (depressive symptoms, sleep disturbances, and anxiety problems).
Methods
This is a secondary analysis of existing data collected in 2019 from the Japan National Health and Wellness Survey. The schizophrenia patients were categorized based on their Patient Health Questionnaire-9 score, self-reported experience of sleep disturbances, and anxiety problems. The lifetime prevalence was estimated using the total number of diagnosed schizophrenia patients as the numerator and the total number of respondents as the denominator. The HRQoL was evaluated through the Short Form 12-Item (version 2) Health Survey and EuroQoL 5-dimensions scale. Work productivity and annual indirect costs were evaluated through the Work Productivity and Activity Impairment instrument and monthly wage rates. Multivariate analyses included the comparison of outcomes using generalized linear models.
Results
The study was conducted with 178 schizophrenia patients with an average age of 42.7 years old and an estimated lifetime prevalence of 0.59% (95% CI: 0.51%, 0.68%). Patients who experienced sleep disturbances, more severe depressive symptoms, and anxiety problems had lower HRQoL, higher levels of absenteeism, presenteeism, total work productivity and activity impairment, and almost twice more indirect costs, compared to those without these conditions.
Conclusion
Comorbid conditions among patients with schizophrenia impact significantly on their quality of life, work productivity as well as indirect costs.

Canine lymphoma/leukemia cell lines with p16 protein expressions: high (17–71 and GL-1) and low (CLBL-1, CLC, Nody-1, and UL-1) were treated in vitro with cyclin-dependent kinase 4 and 6 (CDK4/6) ...inhibitors, palbociclib or abemaciclib. Cell proliferation decreased as a result, with higher IC50 levels observed in the high p16 (17–71 and GL-1) and one low p16 (UL-1) cell lines compared with the low p16 cells (CLBL-1, CLC, and Nody-1). As expected, palbociclib and abemaciclib treatment reduced pRb phosphorylation in a dose-dependent manner, especially in cells with low p16. These results suggest that CDK4/6 inhibitors have potential as new chemotherapeutic agents for canine lymphoma and high p16 protein expression may be used as a biomarker for resistance to CDK4/6 inhibitor therapy.
We performed an Empirical Orthogonal Function (EOF) analysis to assess the intraseasonal variability of 5–60 day band-pass filtered Antarctic sea-ice concentration in austral winter using a 20-year ...daily dataset from 1995 to 2014. Zonal wave number 3 dominated in the Antarctic, especially so across the west Antarctic. Results showed the coexistence of stationary and propagating wave components. A spectral analysis of the first two principal components (PCs) showed a similar structure for periods up to 15 days but generally more power in PC1 at longer periods. Regression analysis upon atmospheric fields using the first two PCs of sea-ice concentration showed a coherent wave number 3 pattern. The spatial phase delay between the sea-ice and mean sea-level pressure patterns suggests that meridional flow and associated temperature advection are important for modulating the sea-ice field. EOF analyses carried out separately for El Niño, La Niña and neutral years, and for Southern Annular Mode positive, negative and neutral periods, suggest that the spatial patterns of wave number 3 shift between subsets. The results also indicate that El Niño-Southern Oscillation and Southern Annular Mode affect stationary wave interactions between sea-ice and atmospheric fields on intraseasonal timescales.
Premature mortality, frequent relapse that easily leads to hospitalization, and discontinuous employment are key challenges for the treatment of schizophrenia. We evaluated risk factors for important ...clinical outcomes (death, hospitalization, resignation, and sick leave from work) in patients with schizophrenia in Japan.
A nested case-control study was conducted for patients with schizophrenia identified in a Japanese claims database. For each outcome, the case was matched with up to four controls of the same age, sex, index year, and enrollment status (employee or dependent family). Potential risk factors were defined by prescriptions or diagnoses within 3 months prior to or in the month of the event. The association among potential risk factors and each outcome was evaluated using multivariable conditional logistic regression analysis with stepwise variable selection.
The number of cases and eligible patients for each outcome were 144 and 38,451 (death), 1,520 and 35,225 (hospitalization), 811 and 18,770 (resignation), and 4,590 and 18,770 (sick leave), respectively. Depression was a risk factor for death (odds ratio OR: 1.92; 95% confidence interval CI: 1.12, 3.29), hospitalization (OR: 1.22; 95% CI: 1.05, 1.42), and sick leave from work (OR: 1.46; 95% CI: 1.36, 1.57). Other risk factors for death were hospitalization history, Charlson Comorbidity Index (CCI) score, and prescription for laxatives. Prescriptions for hypnotics, laxatives, and anticholinergics were risk factors for hospitalization. Prescriptions for hypnotics and anticholinergics were risk factors for resignation. CCI score, prescription for hypnotics, laxatives, and antidiabetics were risk factors for sick leave from work.
Our findings suggest that depression and some physical symptoms, such as constipation and extrapyramidal symptoms, are risk factors for important clinical outcomes in patients with schizophrenia. Attention should be paid to both depression and physical symptoms for the treatment of schizophrenia.
