Full textIn this study, I have explored how leadership at a distance was carried out by managing directors within the field of laboratory medicine. The purpose of the study was to investigate how the directors described the distinctive features of leadership at a distance, including the traits they felt were necessary for effective leadership and the manner in which they communicated with their employees. During the course of the study, I conducted interviews with eight directors employed at different organizational levels; six of the interviewees worked for two separate county councils, and the remaining two for a private healthcare provider. Upon review of the interview transcripts, nine different themes emerged as important: specific traits, delegation, travel, motivation and feedback, coordinating communication, forms of communication, types of meetings, employee performance reviews and information. One key characteristic of leadership at a distance was the fact that directors devoted a large portion of their work week to traveling—either to visit employees or to attend meetings. Delegation of tasks by directors to employees was also found to be important. The results of the study also indicated that, in order to lead effectively at a distance, directors needed to possess a good capacity for communicating, both in writing and in speech. In addition, directors' instructions needed to be exceedingly clear, lest they be misunderstood. Because employees were dispersed geographically, meetings in which all employees were simultaneously in attendance were difficult to bring about. Other types of meetings included telephone and video conferences. Employees received information both during meetings and by way of e-mail, intranet and telephone.

Full textAccording to the National Board of Health and Welfare, SOSFS 2005:12, it is required that the caregiver adheres to his work through following stated objectives. Formulating goals in health care requires careful consideration. Goals must be measurable and include many different aspects of the project. Each improvement project is unique and should be directly related to the resources allocated to the project. A major problem for continuous monitoring is to select parameters that provide sufficient information and are easy to produce. This requires more advanced computer systems and integration with existing computer systems. The paper discusses the parameters an improvement project in laboratory medicine can evaluate its results after. There are currently no standardized quality parameters in clinical chemistry. The parameters used in this study that proved to be the most suitable to be used continuously in the short term was the response times, staffing and reagent costs. In the long term, the above data are combined with indicators that show cost per analysis score and analysis points per full-time employees. The indicator that may be used when the computer system is developed is deviation systems and analytical comments that show for example that a response has not been disclosed.

Full textTyp-2 diabetes har blivit en vanligare sjukdom. De komplikationer som kan uppstå vid diabetes, särskilt obehandlad diabetes, är ofta kardiovaskulära komplikationer. Trombocyter är viktiga komponenter i hemostasen, en av deras funktioner är trombocytadhesion. Trombocytadhesionen är första steget vid bildandet av en trombocytpropp, tillsammans med subendoteliala proteiner så kan trombocyterna fästa till kärlväggen och hemostasen påbörjas. Blodlipider bidrar till cellmembraners struktur, energiförvaring och har en viktig roll vid olika typer av signalering. De har en nyckelroll vid trombocytaktivering eftersom trombocytaktivering är associerad med förändringar som sker hos membranlipiderna. C-reaktivt protein (CRP) är ett akutfasprotein och ökar vid inflammation. Fysiologiska rollen är inte helt känd men stegring av CRP ökar risken för kardiovaskulära komplikationer. Syftet med denna studie är att analysera korrelationen mellan trombocytadhesion med blodlipider och högkänsligt CRP hos typ 2 diabetiker. Det medverkade 69 patienter med typ-2 diabetes i studien. Blodlipider, högkänsligt CRP och trombocytadhesion analyserades ochvärdena för respektive analyt användes för korrelationsanalyser.Resultaten visar statistiskt signifikanta positiva korrelationer mellan ApoA-1, HDL och trombocytadhesion samt signifikanta negativa korrelationer mellan LDL, ApoB/ApoA-1-kvot, LDL/HDL-kvot och trombocytadhesion. ApoA-1 och trombocytadhesion med kollagen som proteinyta uppvisade statistiskt signifikanta korrelationsintervall med r-värden på 0,299-0,436. ApoA-1/ApoB-kvoten visade statistiskt signifikanta korrelationsintervall med r-värdenmellan -0,492 till -0,268. Majoriteten av korrelationerna för variablerna: totalkolesterol, ApoB, triglycerider, högkänsligt CRP och trombocytadhesion visade inga statistiskt signifikanta korrelationer.

Full textDiagnosis of vitamin B12-defiency anemia has been challenging due to lack of ”gold standard” and poor sensitivity of total B12 as a first line marker. With the aim of improving diagnostic of anemia investigations at county hospital Ryhov, Jönköping, we performed a method verification for active B12 on ARCHITECT i2000SR and evaluated the usefulness of active B12 in diagnosing anemia. Correlation analysis was performed using samples with different total B12 ranges: low (n=10, <148 pmol/L), grey zone (n=10, 149-200 pmol/L) and normal (n=10, 201-250 pmol/L). Receiver operating characteristic (ROC) curve was created and area under the curve (AUC) was calculated for determining accuracy of active B12 using 14 deficiency cases. Coefficient of variation (CV) for within-run and total imprecision, for active B12 was 2,4 % and 4,4 %, respectively. Weak correlation was found between B12-ranges, however a moderate correlation (R=0,600) was found including all groups. Active B12 with the cut-off value of 40 pmol/L resulted in high specificity (75%) and sensitivity (80%) and had an AUC of 90 %. Active B12 assay on ARCHITECT i2000SR allows a precise measurement of active B12 in human serum and therefore is adequate for routine use. Active B12 had high accuracy and can be recommended in anemia investigations in county hospital Ryhov, Jönköping.

Full textDuctal carcinoma of the breast is the most common form of invasive breast tumours. The grading system for breast cancer is defined by Elston and Ellis and is based on three criterions. One of these criterions is the mitotic count in pathological sections of breast carcinomas stained with Hematoxylin Eosin. A common method often applied as a complement in diagnosis of breast carcinoma is immunohistochemical staining with use of antibodies directed against Ki67, a proliferation marker. Phosphohistone H3 is a histone protein that is located in the cell nucleus. The protein is believed to be a specific marker for mitosis since it only is phosphorylated during mitosis, and to some extent at the end of the G2-phase. The purpose of this study was to evaluate pHH3 as a potential marker for mitosis when diagnosing ductal breast cancer. The purpose was also to compare the method to mitotic figuring and the count of Ki67-positive cells, and to study the inter-individual variability when assessing the histological sections. The material consisted of 20 biopsies containing invasive ductal breast cancer. The sections were stained using IHC and all sections were evaluated microscopically. Cells positive for pHH3, Ki67 and mitotic cells were quantified, by three doctors. From the doctors results an average value was determined for each case and method. To be able to compare the methods the coefficient of variation was calculated. The average value of the coefficient of variation was determined for each method and also the standard deviation (SD). The coefficient of variation showed average values of 0,21 for Ki67 +/- 0,10 SD, 0,33 for pHH3 +/- 0,14 SD and 0,46 for mitotic figuring +/- 0,34 SD. The correlation coefficients for the methods and each doctor showed dispersion. The correlations showed average values of r = 0,78 for Ki67 and pHH3, r = 0,74 for Ki67 and mitosis and r = 0,83 for pHH3 and mitosis. According to this study it seems as though anti-pHH3 could complement the other methods. However explicit criteria which defines a threshold value of which cells should be considered pHH3-positive needs to be established. The inter-individual differences seem to decrease using antipHH3 compared with mitotic counting, which is more time consuming. Although the minimum difference can be seen when assessing anti-Ki67 as a proliferation marker.

Full textCholesterol is transported in the blood by lipoproteins. High levels of low-density lipoprotein (LDL)-cholesterol in the blood is a risk factor for cardiovascular disease. The concentration of LDL-cholesterol can be calculated using the Friedewald formula but there are also methods that measure LDL-cholesterol directly. The aim of this study was to verify the method P-LDL-cholesterol on a Beckman Coulter AU680 analyzer. Within-run imprecision and total imprecision were analyzed. The correlation between direct LDL-cholesterol and calculated LDL-cholesterol was examined using 43 patient samples with triglyceride levels < 4,5 mmol/L and 11 patient samples with triglyceride levels > 4,5 mmol/L. The Friedewald formula is not supposed to be used on triglyceride levels > 4,5 mmol/L, but in this case the formula was used anyway to evaluate differences between the methods at high triglyceride concentrations. The coefficient of variation (CV) for the within-run imprecision was about 0,5 %, both for the low control (A1) and the high control (A2). Total imprecision had a CV of 1,21 % for A1 and 1,11 % for A2. There was a linear relationship between the methods, but the direct method gave slightly higher results at low concentrations and slightly lower results at high concentrations compared to calculated LDL-cholesterol. At triglyceride levels > 4,5 mmol/L the results from the direct method was considerably higher than calculated LDL-cholesterol. The conclusion is that the precision of the method was good. The correlation between the results from direct LDL-cholesterol and calculated LDL-cholesterol was relatively high for samples with triglyceride levels < 4,5 mmol/L. At triglyceride levels > 4,5 mmol/L there was a big difference between the methods, probably because of falsely low results from calculated LDL-cholesterol.

Full textWarfarin is a drug used to prevent high-risk patients such as those with atrial fibrillation from thromboembolisms. This effect is achieved by suppressing vitamin-K dependent factors VII, X and prothrombin and therefore decreasing the bloods ability to clot. Finding the right dosage of the drug for warfarin treated patients has proven difficult, as it demands regular blood draws to monitor their prothrombin complex level, which is affected by dietary and living habits. The most common way to measure prothrombin complex levels is by using venous plasma but it is also possible to use capillary plasma. Whole blood can be used for mechanical methods, which don’t use optical detection. The benefit is that whole blood doesn’t require centrifugation. The aim of this study was to investigate if there was a significant difference (p≤0,05) between using whole blood and plasma which is the existing method for capillary sample and also if there is any differences between the stability of these samples. Double samples from 30 warfarin treated patients and 5 non-treated persons were taken. One of the samples were centrifuged and analyzed on plasma and the other analyzed on whole blood. The results showed that there was a significant difference (p≤0,05) between the methods. Bland-Altman plot comparison showed that 95 % of the whole blood samples would not be higher than 0,25 INR and lower than 0,14 INR. This has low clinical impact. The samples were stored at room temperature for up to 24 hours and reanalyzed. No changes over 10 % in INR values were observed. This study showed that even though there is a significant difference, it is possible to replace the existing method which using plasma with the whole blood instead.
