Survey of self-assessed preparedness for clinical practice in one Croatian medical school

<p>Abstract</p> <p>Background</p> <p>The Croatian higher education system is in the process of reforming its medical curricula to comply with European Union standards. We conducted a survey of students enrolled at the University of Zagreb (Croatia) asking them to rate their perception of preparedness for clinical practice prior to initiation of the reform process. The purpose of the survey was to identify self-perceived deficiencies in education and to establish a reference point for the later assessment of ongoing educational reform.</p> <p>Findings</p> <p>One-hundred and forty seven (N = 147) graduates reported the levels of perceived preparedness on 30 items grouped into 8 educational domains. Main domains were: understanding science, practical skills/patient management, holistic care, prevention, interpersonal skills, confidence/coping skills, collaboration, and self-directed learning. For each item, graduates self assessed their preparedness on a scale ranging from 1 to 4, with 1 = "Very inadequate", 2 = "Somewhat inadequate", 3 = "Somewhat adequate", and 4 = "Very adequate". In 7 out of 8 domains the achieved median score was ≥ 3. Students expressed low confidence (defined when ≥ 25% of respondents supplied a rating for the survey question as: "very inadequate" or "somewhat inadequate") with interpersonal skills (discussing terminal disease, counseling distraught patients, balancing professional and personal life), and in performing certain basic semi-invasive or invasive procedures.</p> <p>Conclusion</p> <p>Zagreb medical graduates identified several deficiencies within educational domains required for standard clinical practice. Ongoing educational efforts need to be directed towards the correction of these deficiencies in order to achieve standards required by the European Union.</p

Dressings and securements for the prevention of peripheral intravenous catheter failure in adults (SAVE): a pragmatic, randomised controlled, superiority trial

Background: Two billion peripheral intravenous catheters (PIVCs) are used globally each year, but optimal dressing and securement methods are not well established. We aimed to compare the efficacy and costs of three alternative approaches to standard non-bordered polyurethane dressings. Methods: We did a pragmatic, randomised controlled, parallel-group superiority trial at two hospitals in Queensland, Australia. Eligible patients were aged 18 years or older and required PIVC insertion for clinical treatment, which was expected to be required for longer than 24 h. Patients were randomly assigned (1:1:1:1) via a centralised web-based randomisation service using random block sizes, stratified by hospital, to receive tissue adhesive with polyurethane dressing, bordered polyurethane dressing, a securement device with polyurethane dressing, or polyurethane dressing (control). Randomisation was concealed before allocation. Patients, clinicians, and research staff were not masked because of the nature of the intervention, but infections were adjudicated by a physician who was masked to treatment allocation. The primary outcome was all-cause PIVC failure (as a composite of complete dislodgement, occlusion, phlebitis, and infection [primary bloodstream infection or local infection]). Analysis was by modified intention to treat. This trial is registered with the Australian New Zealand Clinical Trials Registry, number ACTRN12611000769987. Findings: Between March 18, 2013, and Sept 9, 2014, we randomly assigned 1807 patients to receive tissue adhesive with polyurethane (n=446), bordered polyurethane (n=454), securement device with polyurethane (n=453), or polyurethane (n=454); 1697 patients comprised the modified intention-to-treat population. 163 (38%) of 427 patients in the tissue adhesive with polyurethane group (absolute risk difference −4·5% [95% CI −11·1 to 2·1%], p=0·19), 169 (40%) of 423 of patients in the bordered polyurethane group (–2·7% [–9·3 to 3·9%] p=0·44), 176 (41%) of 425 patients in the securement device with poplyurethane group (–1·2% [–7·9% to 5·4%], p=0·73), and 180 (43%) of 422 patients in the polyurethane group had PIVC failure. 17 patients in the tissue adhesive with polyurethane group, two patients in the bordered polyurethane group, eight patients in the securement device with polyurethane group, and seven patients in the polyurethane group had skin adverse events. Total costs of the trial interventions did not differ significantly between groups. Interpretation: Current dressing and securement methods are commonly associated with PIVC failure and poor durability, with simultaneous use of multiple products commonly required. Cost is currently the main factor that determines product choice. Innovations to achieve effective, durable dressings and securements, and randomised controlled trials assessing their effectiveness are urgently needed

Simian virus 40 vectors for pulmonary gene therapy

<p>Abstract</p> <p>Background</p> <p>Sepsis remains the leading cause of death in critically ill patients. One of the primary organs affected by sepsis is the lung, presenting as the Acute Respiratory Distress Syndrome (ARDS). Organ damage in sepsis involves an alteration in gene expression, making gene transfer a potential therapeutic modality. This work examines the feasibility of applying simian virus 40 (SV40) vectors for pulmonary gene therapy.</p> <p>Methods</p> <p>Sepsis-induced ARDS was established by cecal ligation double puncture (2CLP). SV40 vectors carrying the luciferase reporter gene (SV/<it>luc) </it>were administered intratracheally immediately after sepsis induction. Sham operated (SO) as well as 2CLP rats given intratracheal PBS or adenovirus expressing luciferase served as controls. Luc transduction was evaluated by <it>in vivo </it>light detection, immunoassay and luciferase mRNA detection by RT-PCR in tissue harvested from septic rats. Vector abundance and distribution into alveolar cells was evaluated using immunostaining for the SV40 VP1 capsid protein as well as by double staining for VP1 and for the surfactant protein C (proSP-C). Immunostaining for T-lymphocytes was used to evaluate the cellular immune response induced by the vector.</p> <p>Results</p> <p>Luc expression measured by <it>in vivo </it>light detection correlated with immunoassay from lung tissue harvested from the same rats. Moreover, our results showed vector presence in type II alveolar cells. The vector did not induce significant cellular immune response.</p> <p>Conclusion</p> <p>In the present study we have demonstrated efficient uptake and expression of an SV40 vector in the lungs of animals with sepsis-induced ARDS. These vectors appear to be capable of <it>in vivo </it>transduction of alveolar type II cells and may thus become a future therapeutic tool.</p

Effect of Hypoxia on Expression of Selected Proteins Involved in Regulation of Apoptotic Activity in Striatum of Newborn Piglets

The levels of selected neuroregulatory proteins that inhibit or promote apoptotic cell death were measured in the striatum of piglets subjected to precisely controlled 1 h hypoxic insult followed by 0, 2 and 4 h recovery and compared to sham operated animals. The anti-apoptotic proteins: there were increases in Survivin at 0 (157%, P = 0.031) and 4 h (171%, P = 0.033), in Bcl-XL at 0 (138%, P = 0.028) and 4 h (143%, P = 0.007), in VEGF at 4 h (185%, P = 0.019) and Hsp27 at 2 h (144%, P = 0.05) and 4 h (143%, P = 0.05). The pro-apoptotic proteins: caspases-1 and 7 increased at 4 h (135%, P = 0.05) and (129%, P = 0.038), respectively. Bim increased after 4 h (115%, P = 0.028), Apoptosis Inducing Factor after 2 h (127%, P = 0.048) and Calpain after 4 h (143% of control, P = 0.04). Hypoxia causes increase in levels of both anti- and pro-apoptotic proteins. Their relative activity determines the outcome in terms of cell damage and neuronal deficit

Analysis of the Effect of Race, Socioeconomic Status, and Center Size on Unrelated National Marrow Donor Program Donor Outcomes: Donor Toxicities Are More Common at Low-Volume Bone Marrow Collection Centers

Previous studies have shown that risks of collection-related pain and symptoms are associated with sex, body mass index (BMI), and age in unrelated donors undergoing collection at National Marrow Donor Program (NMDP) centers. We hypothesized that other important factors (race, socioeconomic status (SES), and number of procedures at the collection center) might affect symptoms in donors. We assessed outcomes in 2,726 bone marrow (BM) and 6,768 peripheral blood stem cell (PBSC) donors collected between 2004 and 2009. Pain/symptoms are reported as maximum levels over mobilization and collection (PBSC) or within 2 days of collection (BM) and at 1 week after collection. For PBSC donors, race and center volumes were not associated with differences in pain/symptoms at any time. PBSC donors with high SES levels reported higher maximum symptom levels 1 week post donation (p=0.017). For BM donors, black males reported significantly higher levels of pain (OR=1.90, CI=1.14-3.19, p=0.015). No differences were noted by SES groups. BM donors from low volume centers reported more toxicity (OR=2.09, CI=1.26-3.46, p=0.006). In conclusion, race and SES have a minimal effect on donation associated symptoms. However, donors from centers performing ≤1 BM collection every 2 months have more symptoms following BM donation. Approaches should be developed by registries and low volume centers to address this issue
