    Many people who are suffering from a chronic pain face pe- riods of acute pain and resulting problems during their illness and ade- quate reporting of symptoms is necessary for treatment. Some patients have difficulties in adequately alerting caregivers to their pain or describ- ing the intensity which can impact on effective treatment. Pain and its intensity can be noticeable in ones face. Movements in facial muscles can depict ones current emotional state. Machine learning algorithms can detect pain intensity from facial expressions. The algorithm can ex- tract and classify facial expression of pain among patients. In this paper, we propose a new deep learning model for detection of pain intensity from facial expressions. This automatic pain detection system may help clinicians to detect pain and its intensity in patients and by doing this healthcare organizations may have access to more complete and more regular information of patients regarding their pain

    \ud \ud Non-adherence to tuberculosis (TB) treatment is the leading contributor to the selection of drug-resistant strains of Mycobacterium tuberculosis and subsequent treatment failure. Tanzania introduced a TB Patient Centred Treatment (PCT) approach which gives new TB patients the choice between home-based treatment supervised by a treatment supporter of their own choice, and health facility-based treatment observed by a medical professional. The aim of this study was to assess the extent and determinants of adherence to anti-TB therapy in patients opting for home-based treatment under the novel PCT approach. In this cross-sectional study, the primary outcome was the percentage of patients adherent to TB therapy as detected by the presence of isoniazid in urine (IsoScreen assay). The primary analysis followed a non-inferiority approach in which adherence could not be lower than 75%. Logistic regression was used to examine the influence of potentially predictive factors. A total of 651 new TB patients were included. Of these, 645 (99.1%) provided urine for testing and 617 patients (95.7%; 90%CI 94.3-96.9) showed a positive result. This result was statistically non-inferior to the postulated adherence level of 75% (p<0.001). Adherence to TB therapy under home-based Directly Observed Treatment can be ensured in programmatic settings. A reliable supply of medication and the careful selection of treatment supporters, who preferably live very close to the patient, are crucial success factors. Finally, we recommend a cohort study to assess the rate of adherence throughout the full course of TB treatment

    Clinical outcomes of biliary drainage of malignant biliary obstruction due to colorectal cancer metastases : a systematic review

    Get PDF
    Background and aims: Malignant biliary obstruction is an ominous complication of metastatic colorectal cancer (mCRC). Biliary drainage is frequently performed to relieve symptoms of jaundice or enable palliative systemic therapy, but effective drainage can be difficult to accomplish. The aim of this study is to summarize literature on clinical outcomes of biliary drainage in mCRC patients with malignant biliary obstruction.& nbsp; Methods: We searched Medline and EMBASE for studies that included patients with malignant biliary obstruction secondary to mCRC, treated with endoscopic and/or percutaneous biliary drainage. We summarized available data on technical success, clinical success, adverse events, systemic therapy administration and survival after biliary drainage.& nbsp; Results: After screening 3584 references and assessing 509 full-text articles, seven cohort studies were included. In these studies, rates of technical success, clinical success and adverse events varied between 63%-94%, 42%81%, and 19%-39%, respectively. Subsequent chemotherapy was administered in 17%-56% of patients. Overall survival varied between 40 and 122 days across studies (278-365 days in patients who received subsequent chemotherapy, 42-61 days in patients who did not).& nbsp; Conclusions: Successful biliary drainage in mCRC patients can be challenging to achieve and is frequently associated with adverse events. Overall survival after biliary drainage is limited, but is significantly longer in patients treated with subsequent systemic therapy. Expected benefits of biliary drainage should be carefully weighed against its risks

    Teaching child and adolescent psychiatry to undergraduate medical students - A survey in German-speaking countries

    Get PDF
    Objective To conduct a survey about teaching child and adolescent psychiatry to undergraduate medical students in German-speaking countries. Methods A questionnaire was sent to the 33 academic departments of child and adolescent psychiatry in Germany, Austria, and the German-speaking part of Switzerland. Results All departments responded. For teaching knowledge, the methods most commonly reported were lectures and case presentations. The most important skills to be taught were thought to be how to assess psychopathology in children and how to assess families. For elective courses, the departments reported using a wide range of teaching methods, many with active involvement of the students. An average of 34 hours per semester is currently allocated by the departments for teaching child and adolescent psychiatry to medical students. Required courses are often taught in cooperation with adult psychiatry and pediatrics. Achievement of educational objectives is usually assessed with written exams or multiple-choice tests. Only a minority of the departments test the achievement of skills. Conclusions Two ways of improving education in child and adolescent psychiatry are the introduction of elective courses for students interested in the field and participation of child and adolescent psychiatrists in required courses and in longitudinal courses so as to reach all students. Cooperation within and across medical schools can enable departments of child and adolescent psychiatry, despite limited resources, to become more visible and this specialty to become more attractive to medical students. Compared to the findings in earlier surveys, this survey indicates a trend towards increased involvement of academic departments of child and adolescent psychiatry in training medical students

    Role of the H helix in heparin binding to protein C inhibitor

    Get PDF
    Protein C inhibitor (PCI) is a plasma serine proteinase inhibitor (serpin) that is a major physiological regulator of activated protein C. Inhibition of its target proteinase is accelerated by heparin in a reaction that involves the binding of both inhibitor and proteinase to heparin to form a ternary complex. This study was undertaken to understand the role of the H helix region (residues 264-278) of PCI in heparin binding and used (i) a recombinant truncated PCI fusion protein of the first 294 residues, (ii) H helix synthetic peptides containing single Arg/Lys-->Glu substitutions, and (iii) site-directed Ala mutagenesis of 4 basic residues (Arg-269, Lys-270, Lys-276, and Lys-277) in the H helix region of full-length recombinant PCI (rPCI) expressed in Baculovirus. The PCI fusion protein interfered in heparin-accelerated PCI-proteinase inhibition reactions, and it bound to heparin-Sepharose. Compared to the wild-type PCI fusion protein, deletion of the H helix from the fusion protein resulted in a reduction of both heparin-Sepharose binding and the ability to compete for heparin during PCI-proteinase inhibition reactions. Competition assays with H helix synthetic peptides revealed that the R269E altered peptide was the least effective at blocking heparin-catalyzed PCI-proteinase inhibition reactions. Compared with full-length active wild-type rPCI, R269A: K270A and K276A:K277A rPCI both had reduced heparin-Sepharose binding, but only R269A:K270A rPCI showed a loss of heparin-accelerated proteinase inhibition for both activated protein C and thrombin. We conclude that a major heparin-binding site of PCI is the H helix, unlike its heparin-binding serpin homologues antithrombin and heparin cofactor II, which bind heparin primarily through the D heli

    Things change: Women’s and men’s marital disruption dynamics in Italy during a time of social transformations, 1970-2003

    Get PDF
    We study women’s and men’s marital disruption in Italy between 1970 and 2003. By applying an event-history analysis to the 2003 Italian variant of the Generations and Gender Survey we found that the spread of marital disruption started among middle-highly educated women. Then in recent years it appears that less educated women have also been able to dissolve their unhappy unions. Overall we can see the beginning of a reversed educational gradient from positive to negative. In contrast the trend in men’s marital disruption risk appears as a change over time common to all educational groups, although with persisting educational differentials.determinants, educational differences, event history analysis, gender difference, Italy, marital disruption

    On reminder effects, drop-outs and dominance: evidence from an online experiment on charitable giving

    Get PDF
    We present the results of an experiment that (a) shows the usefulness of screening out drop-outs and (b) tests whether different methods of payment and reminder intervals affect charitable giving. Following a lab session, participants could make online donations to charity for a total duration of three months. Our procedure justifying the exclusion of drop-outs consists in requiring participants to collect payments in person flexibly and as known in advance and as highlighted to them later. Our interpretation is that participants who failed to collect their positive payments under these circumstances are likely not to satisfy dominance. If we restrict the sample to subjects who did not drop out, but not otherwise, reminders significantly increase the overall amount of charitable giving. We also find that weekly reminders are no more effective than monthly reminders in increasing charitable giving, and that, in our three months duration experiment, standing orders do not increase giving relative to one-off donations
