CAMSAP3 is required for mTORC1-dependent ependymal cell growth and lateral ventricle shaping in mouse brains.

Microtubules (MTs) regulate numerous cellular processes, but their roles in brain morphogenesis are not well known. Here, we show that CAMSAP3, a non-centrosomal microtubule regulator, is important for shaping the lateral ventricles. In differentiating ependymal cells, CAMSAP3 became concentrated at the apical domains, serving to generate MT networks at these sites. Camsap3-mutated mice showed abnormally narrow lateral ventricles, in which excessive stenosis or fusion was induced, leading to a decrease of neural stem cells at the ventricular and subventricular zones. This defect was ascribed at least in part to a failure of neocortical ependymal cells to broaden their apical domain, a process necessary for expanding the ventricular cavities. mTORC1 was required for ependymal cell growth but its activity was downregulated in mutant cells. Lysosomes, which mediate mTORC1 activation, tended to be reduced at the apical regions of the mutant cells, along with disorganized apical MT networks at the corresponding sites. These findings suggest that CAMSAP3 supports mTORC1 signaling required for ependymal cell growth via MT network regulation, and, in turn, shaping of the lateral ventricles.

Functional evaluation of BRCA1/2 variants of unknown significance with homologous recombination assay and integrative in silico prediction model.

Numerous variants of unknown significance (VUSs) exist in hereditary breast and ovarian cancers. Although multiple methods have been developed to assess the significance of BRCA1/2 variants, functional discrepancies among these approaches remain. Therefore, a comprehensive functional evaluation system for these variants should be established. We performed conventional homologous recombination (HR) assays for 50 BRCA1 and 108 BRCA2 VUSs and complementarily predicted VUSs using a statistical logistic regression prediction model that integrated six in silico functional prediction tools. BRCA1/2 VUSs were classified according to the results of the integrative in vitro and in silico analyses. Using HR assays, we identified 10 BRCA1 and 4 BRCA2 VUSs as low-functional pathogenic variants. For in silico prediction, the statistical prediction model showed high accuracy for both BRCA1 and BRCA2 compared with each in silico prediction tool individually and predicted nine BRCA1 and seven BRCA2 variants to be pathogenic. Integrative functional evaluation in this study and the American College of Medical Genetics and Genomics and the Association for Molecular Pathology (ACMG/AMP) guidelines strongly suggested that seven BRCA1 variants (p.Glu272Gly, p.Lys1095Glu, p.Val1653Leu, p.Thr1681Pro, p.Phe1761Val, p.Thr1773Ile, and p.Gly1803Ser) and four BRCA2 variants (p.Trp31Gly, p.Ser2616Phe, p.Tyr2660Cys, and p.Leu2792Arg) were pathogenic. This study demonstrates that integrative evaluation using conventional HR assays and optimized in silico prediction comprehensively classified the significance of BRCA VUSs for future clinical applications.

BRCA2 represses the transcriptional activity of pS2 by E2-ERα.

Germline mutations to the breast cancer 2 (BRCA2) gene have been associated with hereditary breast cancer. In addition to estrogen uptake, BRCA2 expression increases in the S phase of the cell cycle and largely contributes to DNA damage repair associated with DNA replication. However, the role of BRCA2 in estrogen induction remains unclear. An expression plasmid was created to induce BRCA2 activation upon the addition of estradiol by introducing mutations to the binding sequences for the transcription factors USF1, E2F1, and NF-κB within the promoter region of BRCA2. Then, the estrogen receptor (ER) sites of the proteins that interact with BRCA2 upon the addition of estradiol were identified. Both proteins were bound by the helical domain of BRCA2 and activation function-2 of the ER, suggesting that this binding may regulate the transcriptional activity of pS2, a target gene of the estradiol-ER, by suppressing the binding of SRC-1, a coactivator required for activation of the transcription factor.

CDK1 inhibitor controls G2/M phase transition and reverses DNA damage sensitivity.

CDK1 plays key roles in cell cycle progression through the G2/M phase transition and activation of homologous recombination (HR) DNA repair pathway. Accordingly, various CDK1 inhibitors have been developed for cancer therapy that induce prolonged G2 arrest and/or sensitize cells to DNA damaging agents in tumor cells, resulting in cell death. However, CDK1 inhibition can induce resistance to DNA damage in certain conditions. The mechanism of different DNA damage sensitivity is not completely understood. We performed immunofluorescence and flow cytometry analysis to investigate DNA damage responses in human tumor cells during low and high dose treatments with RO-3306, a selective CDK1 inhibitor. This comparative investigation demonstrated that RO-3306-induced G2 arrest prevented cells with DNA double-strand breaks from transitioning into the M-phase and that the cells maintained their DNA repair capacity in G2-phase, even under RO-3306 dose-dependent DNA repair inhibition. These findings reveal that CDK1 inhibitor-induced DNA repair inhibition and cell cycle control, which regulate each other during the G2/M phase transition determine the cellular sensitivity to DNA damage, providing insight useful for developing clinical strategies targeting CDK1 inhibition in tumor cells.

CAMSAP3 maintains neuronal polarity through regulation of microtubule stability.

The molecular mechanisms that guide each neuron to become polarized, forming a single axon and multiple dendrites, remain unknown. Here we show that CAMSAP3 (calmodulin-regulated spectrin-associated protein 3), a protein that regulates the minus-end dynamics of microtubules, plays a key role in maintaining neuronal polarity. In mouse hippocampal neurons, CAMSAP3 was enriched in axons. Although axonal microtubules were generally acetylated, CAMSAP3 was preferentially localized along a less-acetylated fraction of the microtubules. CAMSAP3-mutated neurons often exhibited supernumerary axons, along with an increased number of neurites having nocodazole-resistant/acetylated microtubules compared with wild-type neurons. Analysis using cell lines showed that CAMSAP3 depletion promoted tubulin acetylation, and conversely, mild overexpression of CAMSAP3 inhibited it, suggesting that CAMSAP3 works to retain nonacetylated microtubules. In contrast, CAMSAP2, a protein related to CAMSAP3, was detected along all neurites, and its loss did not affect neuronal polarity, nor did it cause increased tubulin acetylation. Depletion of α-tubulin acetyltransferase-1 (αTAT1), the key enzyme for tubulin acetylation, abolished CAMSAP3 loss-dependent multiple-axon formation. These observations suggest that CAMSAP3 sustains a nonacetylated pool of microtubules in axons, interfering with the action of αTAT1, and this process is important to maintain neuronal polarity.

Cost-utility analysis of aprepitant for patients who truly need it in Japan.

PURPOSE: Neurokinin-1 receptor antagonist (NK1RA) is recommended to prevent chemotherapy-induced nausea and vomiting (CINV) in patients who receive highly or moderately emetogenic chemotherapy (HEC or MEC, respectively). We previously reported that aprepitant, an NK1RA, was needed to control CINV in 43% and 12% of patients who received HEC and MEC, respectively (Support Care Cancer 23:905-912, 2015). To elucidate the cost-effectiveness of aprepitant in these patients, a cost-utility analysis according to the necessity of aprepitant was performed. METHODS: A decision-analytic model was developed according to the necessity of aprepitant and CINV responses in both acute and delayed phases of chemotherapy. Probabilities of health states and medical costs were derived from the results of the abovementioned trial. RESULT: In patients who received HEC and needed aprepitant, the incremental cost-effectiveness ratio (ICER) with aprepitant, relative to the regimen with no aprepitant, was 7912 US dollars (USD) per quality-adjusted life year (QALY) gained, which was far below the commonly accepted threshold of 50,000 USD/QALY. The ICER was 27,457 USD/QALY in patients who received MEC and needed aprepitant. In contrast, in patients who received HEC or MEC but did not need aprepitant, the ICER was 175,959 or 478,844 USD/QALY, respectively. CONCLUSION: Regardless of whether a patient received HEC or MEC, aprepitant use was highly cost-effective for patients who truly needed it. These results warrant further research to predict the necessity of NK1RA treatment before initiating emetogenic chemotherapies.

Coexistence of Alterations of Gastrointestinal Function and Mechanical Allodynia in the Reserpine-Induced Animal Model of Fibromyalgia.

BACKGROUND: Fibromyalgia (FM) is a disorder characterized by widespread chronic pain as core symptom and a broad range of comorbidities. Despite the prevalence of gastrointestinal (GI) comorbidities in patients with FM, GI functions have rarely been investigated in animal models of FM. AIMS: The purpose of the present study is to investigate the coexistence of alterations of GI function in the reserpine-induced myalgia (RIM) rat, a validated FM model associated with disruption of monoamine system. METHODS: Paw withdrawal threshold (von Frey hair test) was assessed as pain-associated indicator. Gastric emptying (13C breath test), small intestinal transit (charcoal meal test), and fecal water content were investigated as GI functions. RESULTS: The specific regimen of reserpine for the RIM rat, i.e., 1 mg/kg s.c., once daily for three consecutive days, caused a reduction of paw withdrawal threshold (i.e., mechanical allodynia) on days 3, 5, and 7 after the first injection. The 13CO2 excreted from the RIM rat was significantly increased on day 7. The RIM rat exhibited an acceleration of small intestinal transit on day 5. Fecal water content collected from the RIM rat was significantly increased on days 3 and 5. The amount of noradrenaline was significantly decreased in GI tissues on days 3, 5, and 7 in the RIM rat. Conclusions This study revealed that accelerated gastric emptying, accelerated small intestinal transit, and increase in fecal water content coexist with mechanical allodynia in the RIM rat, simulating the coexistence of chronic pain and alterations of GI function in patients with FM.

Cost-effectiveness of aprepitant in Japanese patients treated with cisplatin-containing highly emetogenic chemotherapy.

Chemotherapy-induced nausea and vomiting (CINV) remains a major adverse event in cancer chemotherapy. Although aprepitant is effective in preventing CINV, an increment in financial burden for uniform use of aprepitant is a concern. The aim of the present study was to define the cost-effectiveness of aprepitant from the perspective of the Japanese National Health Insurance system. Based on the results of a randomized phase II trial comparing an aprepitant-containing regimen versus a nonaprepitant regimen in Japanese patients who received cisplatin-containing highly emetogenic chemotherapy, a decision analytic model was developed. The incremental cost-effectiveness ratio (ICER) was calculated both in the outpatient care setting (OCS) and in the inpatient care setting (ICS). The use of the aprepitant-containing regimen was associated with improved quality of life compared with the nonaprepitant regimen, with an increment in quality-adjusted life years (QALY) of 0.0016. The incremental total medical costs associated with the use of the aprepitant regimen were lower in the OCS than in the ICS, 6192 JPY (56.92 USD) and 9820 JPY (90.27 USD), respectively. The ICER was calculated as 3 906 698 JPY (35 910 USD) per QALY gained in the OCS and 6 195 781 JPY (56 952 USD) per QALY gained in the ICS. Cost-effectiveness of the aprepitant-containing antiemetic therapy was limited to the OCS, considering the threshold of willingness-to-pay commonly accepted (5 million JPY [45 960 USD] in Japan and 50 000 USD in the USA). The efficacy of aprepitant offsets the costs for revisiting clinics or rehospitalization added with rescue medications in the OCS.

Centrosomal BRCA2 is a target protein of membrane type-1 matrix metalloproteinase (MT1-MMP).

BRCA2 localizes to centrosomes between G1 and prophase and is removed from the centrosomes during mitosis, but the underlying mechanism is not clear. Here we show that BRCA2 is cleaved into two fragments by membrane type-1 matrix metalloproteinase (MT1-MMP), and that knockdown of MT1-MMP prevents the removal of BRCA2 from centrosomes during metaphase. Mass spectrometry mapping revealed that the MT1-MMP cleavage site of human BRCA2 is between Asn-2135 and Leu-2136 ((2132)LSNN/LNVEGG(2141)), and the point mutation L2136D abrogated MT1-MMP cleavage. Our data demonstrate that MT1-MMP proteolysis of BRCA2 regulates the abundance of BRCA2 on centrosomes.

A case of gray platelet syndrome masked by immune thrombocytopenia at presentation.

We report a case of gray platelet syndrome (GPS) associated with immune thrombocytopenia (ITP) at presentation. A 22-year-old male patient presenting with petechiae on his limbs was diagnosed with ITP due to a gradual decrease of his platelet count to a minimum of 26 × 10(9) /liter and an elevated platelet-associated IgG (PA-IgG) level in the absence of any other specific cause of thrombocytopenia. Administration of prednisolone increased his platelet count, but this dropped again to approximately 50 × 10(9) /liter as the dose was tapered, and remained at the same level after the treatment was terminated. Thirteen years later, we reassessed the cause of the thrombocytopenia because the PA-IgG level was found to be within the normal range. There were large hypogranular platelets on the blood film and a deficit of α-granules in the platelets on electron microscopy. On this basis, we diagnosed his thrombocytopenia as GPS. To our knowledge, this is the first report of a GPS case associated with ITP at presentation. This case illustrates the importance of carefully reviewing blood film results in the differential diagnosis of thrombocytopenia.

[A case of Ifosfamide-induced dysuria which could be avoided by changing the regimen of mesna].

A 39-year-old woman with advanced and recurrent cervical carcinoma received chemotherapy with IFM+CDDP(IFM 5, 000mg/m2 by intravenous infusion for 24 hours and CDDP 50 mg/m2 by intravenous infusion for one hour)in September of 2011. Mesna(3, 200mg/body)was administered intravenously for 30min three times a day to prevent IFM-induced hemorrhagic cystitis. She complained of residual urine from the evening of day 2 and felt pain during urination from day 3 (urinary tract pain: Grade 1 CTCAE v4.0 ). Both symptoms continued until day 6. When the infusion rate of mesna was changed to 24 hours of continuous administration, as with IFM on the second course, no symptoms which occurred during the first course were observed. The chemotherapy could be continued without compromising her QOL. The present finding suggests that IFM-induced dysuria could be avoided by changing the regimen to mesna, due to the increase in its binding potency and the metabolite of IFM, acrolein.

[Preparation of dealcholized onetaxotere®, docetaxel injection formulation and its pharmacokinetics in rats].

Onetaxotere®(OTAX)injection, which is a docetaxel(DOC)injection formulation, cannot be administered to those patients with alcohol intolerance or hypersensitivity, because it contains ethanol as a dissolving agent. To broaden treatment options for those patients, we tried to eliminate ethanol from OTAX injection. Under sterile conditions, dealcoholization was carried out using nitrogen gas in a hot water bath at 50°C. By this method, the ethanol included in OTAX injection was almost completely removed and DOC in the formulation was stable for 28 days. When the dealcoholized or untreated OTAX injection was intravenously injected in rats, no significant differences in the pharmacokinetic parameters of DOC were observed between those with dealcoholized and untreated OTAX injections. It is expected that dealcoholized OTAX may be useful in patients with alcohol-related difficulties.

Alleviation of Dyspnea and Changes in Physical Activity Level by Air Flow to the Face With a Fan.

BACKGROUND: Dyspnea is an unpleasant subjective symptom and is associated with decreased physical activity level (PAL). Effect of blowing air toward the face has received a great deal of attention as a symptomatic therapy for dyspnea. However, little is known about the duration of its effect and its impact on PAL. Therefore, this study aimed to measure dyspnea severity and changes in dyspnea and PALs with air blasts to the face. METHODS: The trial conducted was open-label, randomized, and controlled. This study included out-patients with dyspnea caused by chronic respiratory deficiency. Subjects were provided a small fan and instructed to blow air toward their faces either twice a day or when having trouble breathing. Subsequently, severity of dyspnea and PALs was measured using visual analog scale and physical activity scale for the elderly (PASE), respectively, before and after 3-week treatment. Amounts of changes in dyspnea and PALs before and after treatment were compared using analysis of covariance. RESULTS: Overall, 36 subjects were randomized, and 34 were analyzed. Mean age was 75.4 y (26 males [76.5%] and 8 females [23.5%]). Visual analog scale score for dyspnea (SD) before treatment was 33 (13.9) mm and 42 (17.5) mm in the control and intervention groups, respectively. PASE score before treatment was 78.0 (45.1) and 57.7 (38.0) in the control and intervention groups, respectively. No significant difference in changes in dyspnea severity and PAL was observed between the 2 groups. CONCLUSIONS: No significant difference was observed for dyspnea and PALs in subjects after blowing air toward their own faces with a small fan for 3 weeks at home. Disease variability and impact of protocol violations were high due to small number of cases. Further studies with a design focused on subject protocol adherence and measurement methods are required to understand impact of air flow on dyspnea and PAL.

Mechanism of drug interaction between a Kampo medicine, byakkokaninjinto, and tetracycline in rats.

We have previously reported that concomitant oral administration of the Kampo medicine, byakkokaninjinto (TJ-34), in extract granules, reduced the plasma concentrations of tetracycline (TC) and ciprofloxacin in humans, which might be the result of forming a chelate with Ca(2+). In the present study, we investigated the effect of a chelating agent, ethylenediaminetetraacetic acid (EDTA), on the plasma concentration-time profiles of TC after coadministration of TJ-34 dried extract and TC in rats to clarify whether metal ions contained in the TJ-34 dried extract contribute to this interaction. TJ-34 dried extract significantly reduced the plasma concentration of TC. The values of maximum concentration (C (max)), area under the plasma concentration-time curve and percentage of urinary recovery (f (e)) of TC were reduced to 42%, 40%, and 45%, respectively. On the other hand, treatment with EDTA significantly counteracted the effect of TJ-34 dried extract to reduce absorption of TC, indicating that metal ions mainly account for the interaction. Next, we investigated the effect of staggered administration of TJ-34 dried extract and TC to avoid the drug interaction between them. Administration of TJ-34 dried extract 2 h before TC had no effect on plasma concentrations and pharmacokinetic parameters of TC. These results provide a precise mechanism of the interaction TJ-34 and TC, suggesting a safe and effective dosage regimen to coadminister TJ-34 and TC in clinical use.

Evaluation of safety in clinical use of generic paclitaxel [NK] for injection.

PURPOSE: The introduction of generic drugs is a favored strategy in reducing medical costs, but some clinicians are often reluctant to use them because of lack of information with regard to their side effects. Generic paclitaxel [NK] differs from the proprietary version, Taxol®, in containing added citric acid and a more pure form of castor oil. However, little information exists regarding the effects of these additives on adverse events such as vascular pain, phlebitis, hypersensitivity and hepatic dysfunction. To compensate for this lack of information and to validate the safety of using generic paclitaxel, we investigated adverse events in response to generic paclitaxel [NK]. METHODS: Our investigation focused on patients treated with both the proprietary formulation (Taxol® for injection) and the generic version(paclitaxel [NK] for injection)sequentially from April 2008 to March 2009. Adverse events were investigated retrospectively. RESULTS: Incidence of vascular pain, phlebitis and hypersensitivity was similar to that with the original product. Although the expression of some liver enzymes was slightly increased and some gastrointestinal events were reduced following generic paclitaxel [NK] treatment there was no statistically significant difference. The profiles of other adverse events were not significantly different. CONCLUSION: Increased vascular pain and phlebitis, predicted due to low pH conditions caused by citric acid, were not observed. Similarly, the pure castor oil included in generic paclitaxel [NK] did not influence hypersensitivity and hepatic function. We found no significant differences in our study of proprietary and generic paclitaxel [NK]. Thus, clinicians have no reason for prejudice against using generic paclitaxel [NK] on the basis of increased risk of side effects.

Endotoxin does not alter the pharmacokinetics of micafungin, but it impairs biliary excretion of micafungin via multidrug resistance-associated protein 2 (ABCC2/Mrp2) in rats.

Micafungin, a newly developed echinocandin-type antifungal agent, is widely used for the treatment of deep-seated fungal infections including those of Candida species and Aspergillus species. In the present study, the possible alterations in the pharmacokinetics and biliary excretion of micafungin were investigated in endotoxemic rats induced by Klebsiella pneumoniae endotoxin. Endotoxin (2 mg/kg) was injected intraperitoneally 24 h before an intravenous injection of micafungin (1 mg/kg). No significant differences in the plasma concentration-time curves and pharmacokinetic parameters of micafungin were observed between endotoxin-treated and endotoxin-untreated rats. When endotoxin-treated rats received a constant-rate infusion of micafungin, the biliary clearance of micafungin was significantly decreased, whereas the steady-state plasma concentration did not change. By protein immunoblot analysis, a significant decrease in the expression of hepatic multidrug resistance-associated protein 2 (ABCC2/Mrp2), which is an efflux protein for micafungin, was observed in endotoxin-treated rats. These results suggest that endotoxin-induced decrease in the hepatobiliary excretion of micafungin is caused, at least in part, by the reduction of Mrp2-mediated hepatobiliary transport ability. The present study may provide information suggesting that micafungin can be used for patients with endotoxemia without the need for dosage adjustment.

Involvement of sulfate conjugation and multidrug resistance-associated protein 2 (Mrp2) in sex-related differences in the pharmacokinetics of garenoxacin in rats.

In this study, the involvement of sulfate conjugation and drug efflux transporter multidrug resistance-associated protein 2 (Mrp2) in sex-related differences in the pharmacokinetics of a new quinolone antimicrobial agent, garenoxacin, was investigated in Sprague-Dawley (SD) rats and Eisai hyperbilirubinemic rats (EHBRs) lacking Mrp2. The disappearance of garenoxacin from plasma in female SD rats was significantly faster than that in male SD rats after a single intravenous injection of garenoxacin (5 mg/kg). The systemic clearance of garenoxacin in female rats was approximately threefold larger than that of male rats (2.43 ± 0.31 and 0.87 ± 0.06 l/h/kg, respectively), suggesting the existence of sex-related differences in the pharmacokinetics of garenoxacin. When rats received a constant-rate infusion of garenoxacin, the contribution of biliary and renal excretion of garenoxacin was small, and no significant difference in the biliary (CL(BILE)) clearance of garenoxacin was observed between male and female SD rats. The metabolic clearance [CL(M (SULF))] of garenoxacin to garenoxacin sulfate conjugate (which is mainly excreted into the bile) in female SD rats was 8.5-fold larger than that in male SD rats (27.9 ± 2.94 and 3.28 ± 0.07 ml/h/kg, respectively). The CL(BILE) of garenoxacin was decreased in male and female EHBRs by approximately 50% compared with that in male and female SD rats. These results suggest that sulfate conjugation, but not Mrp2, is mainly involved in the sex-related differences in the pharmacokinetics of garenoxacin.

[PARP inhibitors for cancer therapy].

Poly(ADP-ribose)polymerases(PARPs)can transfer their first ADP-ribose moiety from nicotinamide adenine dinucleotide( NAD+)to an acceptor protein. PARPs play a major role in a wide range of biologic processes through poly(ADP-ribosyl) ation, including the maintenance of genomic stability, transcriptional regulation, energy metabolism, and cell death. Recent findings have thrust(PARPs)into the limelight as potential chemotherapeutic targets, and PARP inhibitors(poly(ADP-ribose) polymerase inhibitors)are currently undergoing clinical evaluation for use as new anti-cancer drugs. PARPs promote the repair of single-strand breaks(SSB)by base excision repair(BER), and the inhibition of PARPs leads to the conversion from single-strand breaks(SSB)to double-strand breaks(DSB). Because BRCA1- or BRCA2-deficient cells are unable to complete homologous recombination efficiently, PARP inhibition in these cells causes a high degree of genomic instability and eventual cell death termed synthetic lethality. This synthetic lethal approach has been validated in studies that show a striking single-agent activity of PARP inhibitors in preclinical models of BRCA1 and BRCA2 inactivation. Consistent with these results, the PARP inhibitor olaparib(previously known as AZD2281)has shown promising single-agent activity against it in early clinical testing. In additional studies, the PARP inhibitor has shown remarkable activity in BRCA1- or BRCA2-mutant tumors when used in combination with gemcitabine and carboplatin. Phase I and Phase II trials of several PARP inhibitors in combination with DNA-damaging agents are ongoing.

Assessing the quality of cancer screening leaflets using the International Patient Decision Aids Standards instrument: A cross-sectional content analysis.

OBJECTIVE: To assess the quality of national cancer screening program leaflets in Japan from the informed-decision perspective. METHODS: Cross-sectional content analysis of invitation leaflets issued by centralized organizations and used nationwide in Japan was conducted. Three members independently evaluated the materials using International Patient Decision Aids Standards six-item minimum criteria for qualifying patient decision aids. PATIENT PUBLIC INVOLVEMENT: Co-author KH is a cancer patient himself. We also sought feedbacks from three other cancer survivors and two bereaved family members. RESULTS: Inter-rater agreement was substantial (Fleiss' kappa=0.62). The median score was 2 out of 6 (range: 2-3). All leaflets described the cancer (Q1: 7/7) and screening modality (Q2: 7/7). None stated not undergoing screening as an option. One stated another screening modality (Q3: 1/7). None stated both the positive and negative features of multiple options (Q4: 0/7. Q5: 0/7). One described the psychological and social experience of screening but only its positive side (Q6: 1/7). CONCLUSIONS: There is room for improvement in the content of the public cancer screening invitation leaflets in Japan from informed-decision perspective. PRACTICE IMPLICATIONS: Cancer screening leaflets should provide evidence-based, well-balanced, easy-to-understand information to educate people on cancer screening while maintaining people's autonomy.

Feasibility and acceptability of cognitive rehabilitation during the acute phase of schizophrenia.

AIM: Although numerous studies have demonstrated promising results for the cognitive rehabilitation in subjects with schizophrenia, the efficacy of cognitive rehabilitation for everyday and social functioning is not yet sufficient. Although consideration of the contents and methods are vital, the timing for implementing cognitive rehabilitation also seems to be crucial. The aim of this study was to examine the feasibility and acceptability of cognitive rehabilitation during the acute phase of schizophrenia. METHODS: Patients were recruited from consecutive acute admissions to the inpatient unit during a 15-month period and were evaluated to determine whether they could be enrolled in an 8-week cognitive rehabilitation program within 14 days of their hospital admission. Cognitive rehabilitation programs with a workbook style were adopted, taking the patients' conditions and burdens into consideration. RESULTS: Eighty-three patients were newly admitted during the entry period, and 49 patients (59.0%) were eligible for inclusion. Of them, 22 patients (44.9%) agreed to participate and started the program. Sixteen patients completed the program and underwent a second assessment. Thus, 32.7% (16/49) of all the eligible patients actually completed the study. The participants were quite satisfied with the program. CONCLUSIONS: This preliminary study yielded encouraging data demonstrating the feasibility and acceptability of cognitive remediation for patients with schizophrenia during the acute phase. The provision of cognitive rehabilitation during the acute phase of the first episode can reasonably be expected to lead to better functional outcomes.
