    Get PDF
    Background and Aims: Patients undergoing restorative proctocolectomy have often suffered from active ulcerative colitis which should be remembered when assessing quality of life after operation. The aim of this study was to explore health-related quality of life after restorative proctocolectomy in those with poor or good pouch function and to compare that to patients with active or inactive ulcerative colitis and to the general population. Material and Methods: Altogether, 282 restorative proctocolectomy patients were investigated. The control group comprised 408 ulcerative colitis patients from the local register. Generic 15D and disease-specific inflammatory bowel disease questionnaire health-related quality of life instruments were used. Population-based data were available for 15D. Pouch function was evaluated with oresland score and colitis activity with simple clinical colitis activity index. Results: 15D results showed that patients with good pouch function had health-related quality of life similar to that of the general population. Health-related quality of life with inflammatory bowel disease questionnaire was equally good in patients with good pouch function (n = 131; 70%) and inactive colitis (n = 95; 63%), and equally impaired in patients with poor pouch function (n = 56; 30%) and active colitis (n = 18; 12%). Conclusion: The majority of patients had health-related quality of life comparable to that in general population. Most patients with active ulcerative colitis are likely to improve their health-related quality of life after successful surgery. These findings are important when informing colitis patients about life after surgery.Peer reviewe

    ”Minun luokassa halataan ja jutellaan paljon--.”:noviisiopettajien kertomuksia pedagogisesta hyvinvoinnista

    Tiivistelmä. Tutkimuksemme selvittää noviisiopettajien pedagogiseen hyvinvointiin vaikuttavia tekijöitä narratiivisen tutkimuksen näkökulmasta. Tutkimuksemme tavoitteena on lisätä tietoa opettajien pedagogisesta hyvinvoinnista ja siitä, miten koulutus ja työyhteisö voivat tukea noviisiopettajaa työelämään siirtyessä. Tutkimuskysymyksemme ovat 1) Mitkä tekijät vaikuttavat opettajien pedagogiseen hyvinvointiin? 2) Miten pedagogista hyvinvointia tukeva vuorovaikutus näkyy noviisiopettajien kertomuksissa? Tutkimuksessamme pedagoginen hyvinvointi ymmärretään työhyvinvoinnin yhtenä osa-alueena, jossa korostuu oppimisen ja vuorovaikutuksen näkökulma. Sama näkökulma rakentaa tutkimuksemme taustalla olevan opettajuuden ilmiön. Lisäksi opettajuuteen liittyy vastuu ja eettiset kysymykset. Tutkimuksessamme tarkastelemme pedagogista hyvinvointia noviisiopettajien kertomusten näkökulmasta. Tutkimuksemme aineisto koostuu viiden noviisiopettajan kirjoittamista päiväkirjamerkinnöistä eli kertomuksista. Kertomukset analysoimme aineistolähtöisesti temaattisen narratiivien analyysin keinoin luokittelemalla ne hyvinvoinnin näkökulmasta ala- ja yläteemoihin. Tutkimustulokset rakentuvat yläteemoista, jotka ovat vuorovaikutus, hallinta, ammatillisuus ja henkilökohtaiset voimavarat. Noviisiopettajien pedagogiseen hyvinvointiin vaikuttavat tekijät ovat työssä olevat vuorovaikutussuhteet, opettajien tunne työn hallinnasta, saatavilla olevat resurssit, voimavaratekijät sekä ammatillisuus. Kertomuksissa pedagogista hyvinvointia tukeva vuorovaikutus rakentuu välittämiseen ja myönteisyyteen perustuvaan suhteeseen. Tutkimuksessamme kuuluu aineistomme noviisiopettajien ääni ja heidän kokemuksensa. Tämä lisää ymmärrystä työuraa aloittaneiden opettajien hyvinvointia tukevista tekijöistä. Pedagogisen hyvinvoinnin mukaisesti hyvinvointipuheessa tulisi näkyä opettajien toimijuuden korostaminen ja mahdollisuus ammatilliseen kehittymiseen. Vastuu hyvinvoinnista ei ole yksilöllä itsellään vaan se rakentuu yhteisössä

    Coronary revascularisation in stable patients after an acute coronary syndrome: a propensity analysis of early invasive versus conservative management in a register-based cohort study

    Get PDF
    OBJECTIVES: To compare the effectiveness of in-hospital medical therapy versus coronary revascularisation added to medical therapy in patients who stabilised after an acute coronary syndrome (ACS). DESIGN: Propensity score-matched cohort study from the database of the Tampere ACS registry. SETTING: A single academic hospital in Finland. PARTICIPANTS: 1149 patients with a recent ACS, but no serious coexisting conditions: recurrent ischaemic episodes despite adequate medical therapy, haemodynamic instability, overt congestive heart failure and serious ventricular arrhythmias. PRIMARY AND SECONDARY OUTCOME MEASURES: The composite endpoint of major acute cardiovascular events (MACEs): unstable angina requiring rehospitalisation, stroke, myocardial infarction and all-cause mortality, at 6-month follow-up. RESULTS: Compared with standard medical treatment, revascularisation was associated with a lower rate of MACEs at 6 months in patients of the first quintile (HR 0.81; 95% CI 0.66 to 0.99), but a higher rate of MACEs in the fifth quintile (HR 4.74, CI 1.36 to 16.49; p=0.014). There were no significant differences in the rates of MACEs in the remaining three quintiles. Patients of the first quintile were the oldest (79.7\ub18.3 years) and had a more significant (p<0.001) history of prior myocardial infarction (37%) and poor renal function (creatine, \ub5mol/l: 114.9\ub170.7). They also showed the highest C reactive protein (7.3\ub19.5 mg/l) levels. CONCLUSIONS: Our findings suggest that in-hospital coronary revascularisation did not lead to any advantage with signal of possible harm in the great majority of patients who stabilised after an ACS. An early invasive management strategy may be best reserved for elderly patients having high-risk clinical features and biochemical evidence of a strong inflammatory activity

    Diminished coagulation capacity assessed by calibrated automated thrombography during acute Puumala hantavirus infection

    Coagulation abnormalities are associated with Puumala-virus-induced hemorrhagic fever with renal syndrome (PUUV-HFRS). We evaluated the coagulation capacity of plasma during acute PUUV-HFRS by measuring thrombin generation using calibrated automated thrombography (CAT). The study cohort comprised 27 prospectively collected, consecutive, hospital-treated patients with acute PUUV infection. Blood samples were drawn in the acute phase and at the control visit approximately 5 weeks later. To evaluate thrombin generation, the lag time of initiation, endogenous thrombin potential (ETP), and peak and time to peak thrombin concentration were assessed by CAT in platelet poor plasma without corn trypsin inhibitor. Plasma levels of d-dimer, fibrinogen and prothrombin fragments (F1 + 2) were also evaluated. When the acute phase was compared with the control phase, ETP was decreased (median 1154 nmol/l/min, range 67-1785 vs. median 1385 nmol/l/min, range 670-1970; P <0.001), while the lag time was prolonged (median 3.8 min, range 2.1-7.7 vs. median 2.9 min, range 2.0-4.1; P <0.001). Low ETP correlated with low peak thrombin concentration (r = 0.833, P <0.001). Prolonged time to peak associated with the lag time (r = 0.78, P <0.001). ETP was associated with thrombocytopenia (r = 0.472, P = 0.015) and weakly with fibrinogen level (r = 0.386, P = 0.047). The measured CAT parameters did not associate with d-dimer and F1 + 2 levels. Decreased ETP together with low peak and prolonged lag time indicate decreased plasma potential for thrombin generation in vitro. Together with low platelet count and enhanced fibrinolysis, this further refers to altered blood coagulation and increased propensity toward bleeding in acute PUUV-HFRS.

    Comparison of zero heat flux and double sensor thermometers during spinal anaesthesia : a prospective observational study

    Get PDF
    Because of the difficulties involved in the invasive monitoring of conscious patients, core temperature monitoring is frequently neglected during neuraxial anaesthesia. Zero heat flux (ZHF) and double sensor (DS) are non-invasive methods that measure core temperature from the forehead skin. Here, we compare these methods in patients under spinal anaesthesia. Sixty patients scheduled for elective unilateral knee arthroplasty were recruited and divided into two groups. Of these, thirty patients were fitted with bilateral ZHF sensors (ZHF group), and thirty patients were fitted with both a ZHF sensor and a DS sensor (DS group). Temperatures were saved at 5-min intervals from the beginning of prewarming up to one hour postoperatively. Bland-Altman analysis for repeated measurements was performed and a proportion of differences within 0.5 degrees C was calculated as well as Lin`s concordance correlation coefficient (LCCC). A total of 1261 and 1129 measurement pairs were obtained. The mean difference between ZHF sensors was 0.05 degrees C with 95% limits of agreement - 0.36 to 0.47 degrees C, 99% of the readings were within 0.5 degrees C and LCCC was 0.88. The mean difference between ZHF and DS sensors was 0.33 degrees C with 95% limits of agreement - 0.55 to 1.21 degrees C, 66% of readings were within 0.5 degrees C and LCCC was 0.59. Bilaterally measured ZHF temperatures were almost identical. DS temperatures were mostly lower than ZHF temperatures. The mean difference between ZHF and DS temperatures increased when the core temperature decreased. Trial registration: The study was registered in ClinicalTrials.gov on 13th May 2019, Code NCT03408197.Peer reviewe

    Longitudinal Patterns of Ethical Organisational Culture as a Context for Leaders’ Well-Being: Cumulative Effects Over 6 Years

    Get PDF
    The aim of this longitudinal study was to investigate the temporal dynamics of ethical organisational culture and how it associates with well-being at work when potential changes in ethical culture are measured over an extended period of 6 years. We used a person-centred study design, which allowed us to detect both typical and atypical patterns of ethical culture stability as well as change among a sample of leaders. Based on latent profile analysis and hierarchical linear modelling we found longitudinal, concurrent relations and cumulative gain and loss cycles between different ethical culture patterns and leaders’ well-being. Leaders in the strongest ethical culture pattern experienced the highest level of work engagement and a decreasing level of ethical dilemmas and stress. Leaders who gave the lowest ratings on ethical culture which also decreased over time reported the highest level of ethical dilemmas, stress, and burnout. They also showed a continuous increase in these negative outcomes over time. Thus, ethical culture has significant cumulative effects on well-being, and these longitudinal effects can be both negative and positive, depending on the experienced strength of the culture’s ethicality

    Get PDF
    Objectives: The aim of this controlled follow-up study was to compare the need for revision surgery, long-term efficacy, and satisfaction in chronic rhinosinusitis patients who had undergone maxillary sinus operation with either balloon sinuplasty or traditional endoscopic sinus surgery (ESS) technique. Methods: Thirty-nine ESS patients and 36 balloon patients of our previously described cohort, who had been primarily operated in 2008 to 2010, were contacted by phone. Symptoms, satisfaction, and need for revision surgery were asked. In addition, we collected data of patients who had undergone primary maxillary sinus balloon sinuplasty in the Helsinki University Hospital during the years 2005 to 2019. As a control group, we collected data of patients who had undergone primary maxillary sinus ESS at 3 Finnish University Hospitals, and 1 Central Hospital in years 2005, 2008, and 2011. Results: Altogether, 77 balloon patients and 82 ESS patients were included. The mean follow-up time was 5.3 years in balloon group and 9.8 years in ESS group. Revision surgery was performed on 17 balloon patients and 6 ESS patients. In the survival analysis, the balloon sinuplasty associated significantly with a higher risk of revision surgery compared to ESS. According to the phone interviews, 82% of ESS patients and 75% of balloon patients were very satisfied with the primary operation. Conclusion: Although the patient groups expressed equal satisfaction and change in symptoms after the operations, the need for revision surgery was higher after balloon sinuplasty than after ESS. This should be emphasized when counselling patients regarding surgical options.Peer reviewe

    Bundling up carbon nanotubes through Wigner defects

    Full text link
    We show, using ab initio total energy density functional theory, that the so-called Wigner defects, an interstitial carbon atom right besides a vacancy, which are present in irradiated graphite can also exist in bundles of carbon nanotubes. Due to the geometrical structure of a nanotube, however, this defect has a rather low formation energy, lower than the vacancy itself, suggesting that it may be one of the most important defects that are created after electron or ion irradiation. Moreover, they form a strong link between the nanotubes in bundles, increasing their shear modulus by a sizeable amount, clearly indicating its importance for the mechanical properties of nanotube bundles.Comment: 5 pages and 4 figure
