Abstract
Approximately 10% of ischemic strokes are associated with atrial fibrillation (AF) first diagnosed at the time of stroke. Detecting asymptomatic AF would provide an opportunity to prevent these strokes by instituting appropriate anticoagulation. The AF-SCREEN international collaboration was formed in September 2015 to promote discussion and research about AF screening as a strategy to reduce stroke and death and to provide advocacy for implementation of country-specific AF screening programs. During 2016, 60 expert members of AF-SCREEN, including physicians, nurses, allied health professionals, health economists, and patient advocates, were invited to prepare sections of a draft document. In August 2016, 51 members met in Rome to discuss the draft document and consider the key points arising from it using a Delphi process. These key points emphasize that screen-detected AF found at a single timepoint or by intermittent ECG recordings over 2 weeks is not a benign condition and, with additional stroke factors, carries sufficient risk of stroke to justify consideration of anticoagulation. With regard to the methods of mass screening, handheld ECG devices have the advantage of providing a verifiable ECG trace that guidelines require for AF diagnosis and would therefore be preferred as screening tools. Certain patient groups, such as those with recent embolic stroke of uncertain source (ESUS), require more intensive monitoring for AF. Settings for screening include various venues in both the community and the clinic, but they must be linked to a pathway for appropriate diagnosis and management for screening to be effective. It is recognized that health resources vary widely between countries and health systems, so the setting for AF screening should be both country- and health system-specific. Based on current knowledge, this white paper provides a strong case for AF screening now while recognizing that large randomized outcomes studies would be helpful to strengthen the evidence base.

Abstract
Background: Idiopathic interstitial pneumonia (IIP) is associated with increased risk of acute exacerbation after lung surgery, which has a poor prognosis and can be fatal. Although some studies have investigated acute exacerbation of IIP after lung surgery, the incidence and risks of acute exacerbation of IIP after nonpulmonary surgery have not been reported. The aim of present study to evaluate the characteristics and risk factors for acute exacerbation of IIP after nonpulmonary surgery. Methods: We retrospectively reviewed the clinical characteristics of 2908 consecutive patients (1620 men, 1288 women; mean age, 61.7) who underwent nonpulmonary surgery under general anesthesia between April 2008 to April 2013. Using preoperative chest computed tomography images, we identified IIP cases and compared preoperative characteristics, laboratory findings, and anesthesia conditions among patients who did and did not develop AE. Results: We extracted 103 IIP patients who underwent nonpulmonary surgery; postoperative acute exacerbation of IIP developed in 8 (7.8%). Univariate analysis identified several risk factors, namely, emergency surgery, preoperative prednisolone use, high serum C-reactive protein, lactate dehydrogenase, white blood cell count, low serum albumin and propofol use during anesthesia. Conclusion: The results suggest that the incidences of postoperative acute exacerbation of IIP are similar after nonpulmonary and pulmonary surgery. In addition, propofol use during anesthesia is a possible risk factor for acute exacerbation of IIP after nonpulmonary surgery. (Sarcoidosis Vasc Diffuse Lung Dis 2017; 34: 156-164).

Abstract
Abstract
Background: In patients with HER2-positive metastatic breast cancer (MBC) who progressed on trastuzumab (H)-based therapy, both continuing H beyond progression and switching to lapatinib (L) in combination with chemotherapy are valid options. However, it is unclear which strategy is more effective and how we can select a proper strategy in each patient.
Methods: We conducted an open label, multicenter, randomized phase II trial to comparatively evaluate efficacy and safety of H + capecitabine (X) (HX) or L + X (LX) in women with HER2-positive MBC who were previously treated with taxanes and progressed on H-containing regimens. Patients treated with more than two chemotherapy regimens for MBC were excluded. Those treated with pertuzumab and/or T-DM1 were allowed to enroll in this study. Patients with brain metastases were also included if they are asymptomatic. Patients received H (4mg/kg loading then 2mg/kg weekly or 8mg/kg loading then 6mg/kg every 3 weeks) and X (2500 mg/m2/day on days 1-14 every 3weeks) in HX arm and L (1250 mg/day) and X (2000 mg/m2/day on days 1-14 every 3weeks) in LX arm until progression or intolerable toxicity. The primary endpoint was progression-free survival (PFS) and secondary endpoints included overall survival (OS), objective response rate (ORR), proportion of subjects progressing with brain metastases as site of first progression, and safety.We also assessed biomarkers in tumor tissues and circulating cell-free DNA.
Results: Between May 2011 and December 2014, 86 patients (43 in HX arm and 43 in LX arm) were enrolled in this study. Median age was 58 years (range 34-81), ECOG performance status was 0 (63%), 1 (35%), or 2 (2%), 63% had hormone receptor-positive disease, 15% had brain metastases, 56% had relapsed after primary surgery, and 23% had received adjuvant or neo-adjuvant trastuzumab. Median follow-up time was 44.6 months. Median PFS was 6.1 months in HX arm and 7.1 months in LX arm (hazard ratio 0.81 90% CI 0.55-1.21; p=0.39), median OS was 31.0 months in HX arm and not reached in LX arm (hazard ratio 0.58 95% CI 0.26-1.31; p=0.18), ORR was 40% in HX arm and 41% in LX arm (p=1.00), disease control rate was 73% in HX arm and 92% in LX arm (p=0.038), and proportion of subjects progressing with brain metastases as site of first progression was 5% in HX arm and 5% in LX arm. Grade 3-4 toxicities included hand-foot syndrome (21% in HX arm and 21% in LX arm) and diarrhea (9% in HX arm and 16% in LX arm). In subgroup analyses, PFS benefit in LX arm compared to HX arm was significantly larger among patients who had received previous systemic treatment for metastatic disease for less than 1 year (interaction p=0.007). Subgroup analyses by biomarkers will be presented at the meeting.
Conclusions: In women with HER2-positive MBC previously treated with trastuzumab and taxanes, lapatinib + capecitabine tended to yield better PFS and OS than trastuzumab beyond progression + capecitabine, although they were not statistically significant.Background: In patients with HER2-positive metastatic breast cancer (MBC) who progressed on trastuzumab (H)-based therapy, both continuing H beyond progression and switching to lapatinib (L) in combination with chemotherapy are valid options.

Abstract
Intestinal mucositis accompanied by severe diarrhea is one of the most common side effects during cancer chemotherapy. Lafutidine, a histamine H2 receptor antagonist with mucosal protective properties via sensory afferent neurons, is used for the treatment of upper gastrointestinal diseases. The present study investigated the effects of lafutidine on 5-fluorouracil (5-FU)-induced intestinal mucositis induced in mice. Male C57BL/6 wild-type (WT), sensory deafferented mice, and transient receptor potential vanilloid subfamily 1 knockout (TRPV1KO) mice were used. Animals were administered 5-FU once daily, while lafutidine and famotidine were administered twice daily for 6 days. Repeated administration of 5-FU caused severe intestinal mucositis, characterized by shortening of villi and destruction of crypts and was accompanied by diarrhea and body weight loss. Daily administration of lafutidine reduced the severity of intestinal mucositis, diarrhea and body weight loss in a dose-dependent manner, while famotidine had no effect on intestinal mucositis. The preventive effects of lafutidine were completely abolished in sensory deafferented and TRPV1-KO mice. Lafutidine significantly suppressed 5-FU-increased MPO activity and inflammatory cytokine expression on day 6, but not apoptosis induction in intestinal crypts on day 1. Lafutidine induced Alcian Blue and PAS-positive mucus production in the small intestine. These findings suggest that lafutidine attenuates 5-FU-induced intestinal mucositis, most likely by increasing mucus production via activation of sensory afferent neurons. Furthermore, intact TRPV1 signaling is essential for the activation of sensory afferent neurons induced by lafutidine. Therefore, lafutidine is more useful than other common antacids for the treatment of intestinal mucositis during cancer chemotherapy.

Abstract
Preservation of fertility has been recommended for cancer-bearing patients of reproductive age before undergoing cancer treatment. However, there are many considerations and it is difficult to preserve fertility for all patients undergoing therapy for malignancies. Female cancer survivors had lower pregnancy and live birth rates compared with others that underwent assisted reproductive technologies (ARTs). We should continue to consider the issue of infertility in patients who underwent therapies for malignancies. This is the first report of a successful live birth in a patient with a cranial tumor who underwent radiotherapy and chemotherapy after implantation of an autologous embryo. The patient was a 27-year-old Japanese woman. She was diagnosed with suprasellar germinoma at 13 years of age, and she developed panhypopituitarism after radiotherapy and chemotherapy. At 27 years of age, she began infertility treatment with in-vitro fertilization (IVF). The level of anti-Mallerian hormone (AMH) was 4.29 ng/ml. After ovarian stimulation by high purified human menopausal gonadotropin (HP-hMG), she obtained two blastocysts and became pregnant by implantation of a cryopre- served blastocyst. At 37 gestational weeks, she delivered a healthy female baby by cesarean section.

Abstract
The mes rat is from an inbred mutant colony of rats with spontaneous eosinophilia. In order to investigate the pathogenesis of the mes rat, the histopathology and hematology for 76 mes rats were examined at several weeks of age. Tissue eosinophilia developed at 8 weeks of age when the blood eosinophil was 500 cells per microliter or more. Subsequently, eosinophilia progressed with age, and splenic eosinophilopoiesis and erythropoiesis appeared simultaneously. Many inflammatory lesions were induced after 10 weeks of age when the blood eosinophils became 1,000 cells per microliter or more. Gastroenteritis and mesenteric lymphadenitis were seen in 44 of 47 (94%) and 31 of 47 (66%) rats, respectively, after 10 weeks of age. Aortitis that deteriorated with age was found in 19 of 39 (49%) rats after 12 weeks of age. Hepatic fibrosis was found in four rats that exhibited severe eosinophilia and anemia. These results are comparable to the features of a hypereosinophilic syndrome in humans and other animals.

Abstract
Modified cyclodextrin sulphate (mCDS) in which lipophilic groups were introduced to cyclodextrin sulphate (CDS) was synthesized and proved more inhibitory to the replication of HIV-1 and HIV-2 than CDS or dextran sulphate (DS). The anti-coagulant activity of mCDS was lower than that of DS. Cyclodextrin phosphate (CDP) showed anti-HIV activity similar to that of CDS, and its anti-coagulant activity was even lower than that of mCDS. Flow cytometric analysis suggested that the mechanism of the anti-HIV-1 action of CDS, mCDS, and CDP is based on inhibition of HIV-1 binding to the cells. The peak blood concentration after oral administration of mCDS11(potassium tris[6-benzylthio-6-deoxy]-β-cyclodextrin hexadecasulphate) to rabbits was about 1000 times higher than the concentration showing anti-HIV activity. The retention time in the blood was also long (blood half-life: 4 h). These results point to the potential usefulness of oral mCDS administration in the prophylaxis and/or therapy of HIV infections.

Abstract
We evaluated the flow in experimental pig aneurysms using a high speed video system with tracer particles and digital subtraction angiography (DSA). We found that flow velocity in experimental aneurysms was fast on the inflow of aneurysms. There was a certain correlation between mean transit time (MTT) and velocity in experimental aneurysms. Therefore, the differences of flow velocity in aneurysms will be detected using DSA. The flow in aneurysms was much changed by platinum coil embolization.

Abstract
Flow studies are important to understanding pathogenesis and treatment of cerebral aneurysms, but have not been possible in the clinical setting. We used experimental aneurysms established in and then removed from pigs to compare and correlate flow studies by high-speed video photography of introduced particles and by clinically applicable digital subtraction angiography. Venous pouches were used to create aneurysms in incised common carotid arteries. After aneurysms and parent arteries were removed, specimens were rendered translucent with solvents so they could be studied by video photography of introduced plastic particles in addition to digital subtraction angiography with iodinated contrast material. Regions of interest were studied individually. Mean transit time for contrast in the preparation correlated with videographically measured particle flow velocity (r = 0.616). Digital subtraction angiography should be useful in evaluation of flow in the clinical assessment and treatment of cerebral aneurysms, such as in endovascular therapy.

Abstract
The Matsumoto Eosinophilic Shinshu (MES) rat originated from an inbred mutant colony of rats with spontaneous eosinophilia. As part of an investigation of the pathogenesis of the MES rat, we examined the haematology data for 106 males and 88 females and age-associated changes using an automated haematology analyser, flow cytometric analysis and morphological examination. The data at 10 weeks of age showed the MES rats had higher counts for eosinophils and neutrophils, slightly higher counts for lymphocytes, monocytes, basophils, and large unstained cells (LUCs), and slightly lower values for the erythrocytic parameters when compared with Sprague-Dawley (SD) rats. In data for MES rats aged 8 to 20 weeks, eosinophil counts increased with age up to 20 weeks together with some increased neutrophil counts. After 11 weeks of age, counts for lymphocytes, monocytes, basophils, and LUCs in the MES rats were also slightly increased. In female MES rats, flow cytometric analysis showed increased counts for pan-T+ cells, but blasts, abnormal granulocytes and lymphocytes were not detected morphologically. The MES rat characterized by the haematological findings could be a useful animal model for studies of hypereosinophilia.

Abstract
BACKGROUND Trials of salvage therapy for advanced urothelial carcinoma have required prior platinum-based therapy. This practice requires scrutiny because non-platinum-based first-line therapy may be offered to cisplatin-ineligible patients. PATIENTS AND METHODS Data of patients receiving salvage systemic chemotherapy were collected. Data on prior first-line platinum exposure were required in addition to treatment-free interval, hemoglobin, Eastern Cooperative Oncology Group performance status, albumin, and liver metastasis status. Cox proportional hazard regression was used to evaluate their association with overall survival (OS) after accounting for salvage single-agent or combination chemotherapy. RESULTS Data were obtained from 455 patients previously exposed to platinum-based therapy and 37 not exposed to platinum. In the group exposed to prior platinum therapy, salvage therapy consisted of a single-agent taxane (n = 184) or a taxane-containing combination chemotherapy (n = 271). In the group not exposed to prior platinum therapy, salvage therapy consisted of taxane or vinflunine (n = 20), 5-fluorouracil (n = 1), taxane-containing combination chemotherapy (n = 12), carboplatin-based combinations (n = 2), and cisplatin-based combinations (n = 2). The median OS for the prior platinum therapy group was 7.8 months (95% confidence interval, 7.0, 8.1), and for the group that had not received prior platinum therapy was 9.0 months (95% confidence interval, 6.0, 11.0; P = .50). In the multivariable analysis, prior platinum therapy versus no prior platinum exposure did not confer an independent impact on OS (hazard ratio, 1.10; 95% confidence interval, 0.75, 1.64; P = .62). CONCLUSION Prior platinum- versus non-platinum-based chemotherapy did not have a prognostic impact on OS after accounting for major prognostic factors in patients receiving salvage systemic chemotherapy for advanced urothelial carcinoma. Lack of prior platinum therapy should not disqualify patients from inclusion onto trials of salvage therapy.
