    Abstract In this report, we investigate the effect of low coefficient of thermal expansion (CTE) metals on the operating speed of hafnium-based oxide capacitance. We found that the cooling process of low CTE metals during rapid thermal annealing (RTA) generates in-plane tensile stresses in the film, This facilitates an increase in the volume fraction of the o-phase and significantly improves the domain switching speed. However, no significant benefit was observed at electric fields less than 1 MV/cm. This is because at low voltage operation, the defective resistance (dead layer) within the interface prevents electron migration and the increased RC delay. Minimizing interface defects will be an important key to extending endurance and retention.

    Abstract Background: The aim of the study was to evaluate the comparative risk of self-harm associated with the use of different antidepressants.
    Method: A cohort study was conducted using data from Taiwan's National Health Insurance Research Database from 2001 to 2012. A total of 751 606 new antidepressant users with depressive disorders were included. The study outcome was hospitalization due to self-harm (International Classification of Diseases, Ninth Revision, Clinical Modification codes: E950-E958 and E980-E988). Cox proportional hazards models with stratification of the propensity score deciles were used to estimate the hazard ratios of self-harm hospitalization during the first year following the initiation of antidepressant treatment.
    Results: There were 1038 hospitalization episodes due to self-harm that occurred during the follow-up of 149 796 person-years, with an overall incidence rate of 6.9 [95% confidence interval (CI) 6.5-7.4] per 1000. Compared with fluoxetine, the risk of self-harm hospitalization was higher for maprotiline [adjusted hazard ratio (aHR) = 3.00, 95% CI 1.40-6.45], milnacipran (aHR = 2.34, 95% CI 1.24-4.43) and mirtazapine (aHR = 1.40, 95% CI 1.06-1.86), lower for bupropion (aHR = 0.51, 95% CI 0.30-0.86), and similar level of risk was found for other selective serotonin reuptake inhibitors (citalopram, escitalopram, fluvoxamine, paroxetine and sertraline).
    Conclusions: The risk of self-harm may vary across different antidepressant drugs. It would be of importance to conduct further research to investigate the influence of antidepressant use on self-harm behaviors.

    Abstract Background: This study aimed to review the outcome of patients treated with surgical resection for necrotizing lung infection with various co-morbidities and complications.
    Methods: The records of 26 patients treated with pulmonary resection for necrotizing pneumonia between July 2004 and January 2010 were retrospectively reviewed. Surgical procedures included large wedge resection (n = 1), lobectomy (n = 19) and bilobectomy (n = 6).
    Results: The study cohort consisted of 21 men and 5 women aged 35-85 years (mean 64.7 ± 15.0 years). Twenty-three (88.5%) patients had underlying risk factors. At surgical consultation, 17 patients presented with progressive respiratory distress; 6 required ventilatory support; 12 had empyema, and in 5 patients the conditions were complicated by bronchopleural fistula. Four patients had septic shock requiring vasopressor support. Three patients developed hemoptysis. Two patients had bilateral diffuse pneumonia. Klebsiella pneumoniaeand Streptococcusviridans were the most common pathogens. The right lower (n = 13) and right middle lobes (n = 10) were the most frequently affected. Four deaths (15.4%) occurred: 3 due to perioperative progressing pulmonary infection/inflammation and 1 due to hepatorenal failure. Postoperative empyema occurred in 3 patients. One patient became ventilator dependent.
    Conclusion: Pulmonaryresection for necrotizing pneumonia is a feasible treatment option in patients with progressive pulmonary sepsis.

    Abstract Electron injection by tunneling from a gold electrode and hole transport properties in polycrystalline MAPbI3 has been investigated using variable temperature experiments and numerical simulations. The presence of a large and unexpected band bending at the Au/MAPbI3 interface is revealed and attributed to the trapping of holes, which enhances the injection of electrons via tunneling. These results elucidate the role of volume and interface defects in state-of-the-art hybrid perovskite semiconductors.

    Abstract We report the case of a 41-year-old man with symptoms of exertional dyspnoea and easy fatigue. Physical examination revealed a palpable mass with knocking pain over the right flank region and a cardiac murmur with jugular vein engorgement. Transoesophageal echocardiography revealed a right atrial mass that caused tricuspid inflow obstruction. Computed tomography revealed a giant mass (approximately 15 x 15 cm2) in the right kidney; this finding was consistent with renal cell carcinoma. Despite the metastatic status, right nephrectomy was performed and the intra-atrial tumour thrombus (TT) was resected under a cardiopulmonary bypass in order to relieve the tricuspid obstruction. Histological examination confirmed renal cell carcinoma with TT. The patient is healthy with satisfactory systolic function at 1-year follow-up.

    Abstract We report the case of a 67-year-old man who was found to have asymptomatic murmurs during his health check-up. Echocardiography revealed a mobile spherical mass in the left ventricle (LV), whereas magnetic resonance imaging (MRI) study revealed a well-circumscribed heterogeneous mass in the LV with its base attached to the LV apex. To the best of our knowledge, such a case of hemangioma, particularly its rare location at the apex of the LV, and its asymptomatic conduction disturbance has not yet been reported in the medical literature. Because of successful surgical intervention, the patient is in good health without any further tumor recurrence at 24 months after the diagnosis.

    Abstract Objective: To investigate the predictors of use of anti-amoebiasis protective measures (AAPMs) among Taiwan immigrants returning to their country of origin, using the Health Belief Model (HBM) to guide the investigation.
    Design: Cross-sectional study.
    Methods: Between March and May 2011, all permanent immigrants originating from amoebiasis-endemic countries who received services at the immigrant service centres in Taipei or Tainan and who reported that they had returned to their country of origin within the past five years were enrolled in the study. A structured questionnaire containing questions on sociodemographic characteristics and items related to the constructs of the HBM was used as the data collection instrument.
    Results: Complete information was collected from 384 immigrants, with a response rate of 80% (384/480). The mean age of the subjects was 38.4 years (standard deviation 10.6 years). The majority (70%) of participants did not receive travel information through a pretravel consultation, and more than 17% reported that they did not use measures to prevent amoebiasis. Multiple regression analyses revealed that Chinese proficiency, pretravel consultation and lower barriers to using protective measures were significantly associated with the use of AAPMs during return trips to country of origin (R(2) = 0.45; F = 77.5; P < 0.001).
    Conclusion: The HBM significantly predicted the use of AAPMs in this study. A high proportion of immigrants did not use appropriate AAPMs when they returned to their country of origin. Educational approaches should be targeted at immigrants originating from amoebiasis-endemic regions who return to their country of origin.
