[Therapy of primary hypoadrenocorticism in dogs with low dose desoxycorticosterone pivalate]. / Therapie des primären Hypoadrenokortizismus beim Hund mit niedrig dosiertem Desoxycorticosteronpivalat.

OBJECTIVE: Since 2016 the only approved drug for the treatment of primary hypoadrenocorticism (Addisons disease) in dogs in Germany is desoxycorticosterone pivalate (DOCP), namely Zycortal®. The initial dose recommended by the manufacturer is 2.2 mg/kg. Our own experience and select publications raise the suspicion that a distinctly lower initial dose would be sufficient. Mainly cost reduction motivates for dose reduction and with it comes a higher owner motivation and compliance. It was the objective of our retrospective study to show that an initial dose of 1.5 mg/kg DOCP is sufficient for controlling canine hypoadrenocorticism. MATERIAL AND METHODS: Dogs with primary hypoadrenocorticism were included if the initial starting dose was 1.5 mg/kg DOCP subcutaneously. The first, second and the last known dose of DOCP were documented. Electrolyte concentrations at the time of diagnosis as well as 10-14 days after the first injection, on the day of the second injection as well as at the last known injection were recorded. A dog was considered medically well-regulated when clinically healthy, sodium and potassium concentrations within the reference ranges, and when the responsible veterinarian did not recommended a dose alteration. RESULTS: All 13 included dogs were clinically healthy after the first or second injection. One dog received 1.6 mg/kg DOCP as last documented dose, all other dogs received ≤ 1.5 mg/kg (median: 1.3, range: 0.4-1.6) DOCP. Eleven dogs were injected once monthly, 2 dogs received injections every 60 days. The dogs were followed at least 7 months (median: 20 months, range: 7-26 months). CONCLUSION AND CLINICAL RELEVANCE: We were able to show that a starting dose of 1.5 mg/kg DOCP (Zycortal®) is sufficient for controlling primary hypoadrenocorticism in dogs. Adjustments of the dose are needed in some dogs. Regular measurement of electrolyte concentrations 10 days after treatment initiation and at the monthly DOCP injection is required for a correct disease management with DOCP.

Associations between degrees of task delegation and adherence to COPD guidelines on spirometry testing in general practice - a national cross-sectional study.

BACKGROUND: The healthcare systems in the western world have in recent years faced major challenges caused by demographic changes and altered patterns of diseases as well as political decisions influencing the organisation of healthcare provisions. General practitioners are encouraged to delegate more clinical tasks to their staff in order to respond to the changing circumstances. Nevertheless, the degree of task delegation varies substantially between general practices, and how these different degrees affect the quality of care for the patients is currently not known. Using chronic obstructive pulmonary disease (COPD) as our case scenario, the aim of the study was to investigate associations between degrees of task delegation in general practice and spirometry testing as a measure of quality of care. METHODS: We carried out a cross-sectional study comprising all general practices in Denmark and patients suffering from chronic obstructive pulmonary disease. General practitioners (GPs) were invited to participate in a survey investigating degrees of task delegation in their clinics. Data were linked to national registers on spirometry testing among patients with COPD. We investigated associations using multilevel mixed-effects logit models and adjusted for practice and patient characteristics. RESULTS: GPs from 895 practices with staff managing COPD-related tasks responded, and 61,223 COPD patients were linked to these practices. Hereof, 24,685 (40.3%) had a spirometry performed within a year. Patients had a statistically significant higher odds ratio (OR) of having an annual spirometry performed in practices with medium or maximal degrees of task delegation compared to practices with a minimal degree (OR = 1.27 and OR = 1.33, respectively). CONCLUSION: Delegating more complex tasks to practice staff implies that COPD-patients are more likely to be treated according to evidence-based recommendations on spirometry testing.

Work motivation, task delegation and job satisfaction of general practice staff: a cross-sectional study.

Background: Recent research has shown that a high degree of task delegation is associated with the practise staff's overall job satisfaction, and this association is important to explore since job satisfaction is related to medical as well as patient-perceived quality of care. Objectives: This study aimed: (1) to investigate associations between degrees of task delegation in the management of chronic disease in general practice, with chronic obstructive pulmonary disease (COPD) as a case and the staff's work motivation, (2) to investigate associations between the work motivation of the staff and their job satisfaction. Methods: The study was based on a questionnaire to which 621 members of the practice staff responded. The questionnaire consisted of a part concerning degree of task delegation in the management of COPD in their respective practice and another part being about their job satisfaction and motivation to work. Results: In the first analysis, we found that 'maximal degree' of task delegation was significantly associated with the staff perceiving themselves to have a large degree of variation in tasks, odds ratio (OR) = 4.26, confidence interval (CI) = 1.09, 16.62. In the second analysis, we found that this perceived large degree of variation in tasks was significantly associated with their overall job satisfaction, OR = 2.81, confidence interval = 1.71, 4.61. Conclusion: The results suggest that general practitioners could delegate highly complex tasks in the management of COPD to their staff without influencing the staff's work motivation, and thereby their job satisfaction, negatively, as long as they ensure sufficient variation in the tasks.

Associations between degrees of task delegation and job satisfaction of general practitioners and their staff: a cross-sectional study.

BACKGROUND: In recent years, the healthcare system in the western world has undergone a structural development caused by changes in demography and pattern of disease. In order to maintain the healthcare system cost-effective, new tasks are placed in general practice urging the general practitioners to rethink the working structure without compromising the quality of care. However, there is a substantial variation in the degree to which general practitioners delegate tasks to their staff, and it is not known how these various degrees of task delegation influence the job satisfaction of general practitioners and their staff. METHODS: We performed a cross-sectional study based on two electronic questionnaires, one for general practitioners and one for their staff. Both questionnaires were divided into two parts, a part exploring the degree of task delegation regarding management of patients with chronic obstructive pulmonary disease in general practice and a part concerning the general job satisfaction and motivation to work. RESULTS: We found a significant association between perceived "maximal degree" of task delegation in management of patients with chronic obstructive pulmonary disease and the staff's overall job satisfaction. The odds ratio of the staff's satisfaction with the working environment displayed a tendency that there is also an association with "maximal degree" of task delegation. In the analysis of the general practitioners, the odds ratios of the results indicate that there is a tendency that "maximal degree" of task delegation is associated with overall job satisfaction, satisfaction with the challenges in work, and satisfaction with the working environment. CONCLUSIONS: We conclude that a high degree of task delegation is significantly associated with overall job satisfaction of the staff, and that there is a tendency that a high degree of task delegation is associated with the general practitioners' and the staff's satisfaction with the working environment as well as with general practitioners' overall job satisfaction and satisfaction with challenges in work. To qualify future delegation processes within general practice, further research could explore the reasons for our findings.

Multiple thoracolumbar partial lateral corpectomies in 17 dogs. / Multiple thorakolumbale partielle laterale Korpektomien bei 17 Hunden.

OBJECTIVE: To report feasibility and outcome of multiple thoracolumbar partial lateral corpectomies (TLPLCs) in dogs with predominantly ventral spinal cord compression caused by intervertebral disc disease (IVDD) in the light of reported decreased spinal stability following single TLPLC. Material und methods: In a retrospective study the records of dogs treated by multiple TLPLCs for ventral spinal cord compression caused by Hansen type I or type II IVDD were reviewed. Presurgical spinal cord compression and postsurgical decompression, as well as slot dimensions were determined based on computed tomography (CT)-myelography images. Neurological outcome was assessed based on repetitive examinations applying a modified Frankel Score as well as on an owner questionnaire. RESULTS: Seventeen dogs with a mean body weight of 20.3 kg (range 4.0-49.0 kg) were included. Fourteen dogs had two TLPLCs, two dogs had three TLPLCs and one dog had four TLPLCs performed. The mean slot depth was 63% of entire vertebral body width, the mean slot height was 29% of the entire vertebral body height, the mean slot length was 25% of the entire vertebral body length and the mean residual vertebral interslot length between two adjacent TLPLCs was 55% of the vertebral body length. At reevaluation 4 weeks after surgery, 6/17 dogs (35.3%) had the same modified Frankel Score as before surgery, whereas 11/17 dogs (64.7%) showed a neurological improvement. According to the owners 78.5% of dogs were walking normally within 6 months after surgery. The mean survival time of 16 dogs, where follow-up was available, was 951 days. CONCLUSION AND CLINICAL RELEVANCE: Multiple spinal cord compressions caused by IVDD can be eliminated by multiple, even consecutive, TLPLCs without the risk of a clinically significant risk of spinal instability.

Associations between patients' adherence and GPs' attitudes towards risk, statin therapy and management of non-adherence--a survey and register-based study.

BACKGROUND: Previous studies suggest that doctors' personal lifestyle, risk taking personality and beliefs about risk reducing therapies may affect their clinical decision-making. Whether such factors are further associated with patients' adherence with medication is largely unknown. OBJECTIVE: To estimate associations between GPs' attitudes towards risk, statin therapy and management of non-adherence and their patients' adherence, and to identify subgroups of GPs with poor patient adherence. METHODS: All Danish GPs were invited to participate in an online survey. We asked whether they regarded statin treatment as important, how they managed non-adherence and whether non-adherence annoyed them. The Jackson Personality Inventory-revised was used to measure risk attitude. The GPs' responses were linked to register data on their patients' redeemed statin prescriptions. Mixed effect logistic regression was used to estimate associations between patient adherence and GPs' attitudes. Adherence was estimated by the proportion of days covered in a 1-year period using an 80% cut-off. RESULTS: We received responses from 1398 GPs (42.2%) who initiated statin therapy in 12 192 patients during the study period. In total 6590 (54.1%) of these patients were adherent. Patients who had GPs rarely assessing their treatment adherence were less likely to be adherent than those who had GPs assessing their patients' treatment adherence now and then, odds ratio (OR) 0.86 [confidence interval (CI) 0.77-0.96]. No other associations were found between patients' adherence and GPs' attitudes. CONCLUSIONS: Our findings suggest that GPs' attitudes to risk, statin therapy or management of non-adherence are not significantly associated with their patients' adherence.

Up-regulation of L1CAM is linked to loss of hormone receptors and E-cadherin in aggressive subtypes of endometrial carcinomas.

Endometrial carcinomas (ECs) are classified into type 1 (less aggressive) and type 2 (aggressive) tumours that differ in genetic alterations. So far, reliable immunohistochemical markers that can identify patients with high risk for recurrence are rare. We have defined the expression of L1 cell adhesion molecule (L1CAM), a biomarker previously identified for EC, and compared its expression to oestrogen receptor (ER)/progesterone receptor (PR) and E-cadherin. We found that L1CAM was absent in normal endometrium and the vast majority of endometrioid ECs (type 1) but was strongly expressed in serous and clear-cell ECs, considered as type 2. 78/272 cases were identified as L1CAM-positive endometrioid ECs that were correlated with a poor prognosis. Strikingly, we observed an inverse relationship between L1CAM and ER/PR/E-cadherin expression in all ECs. In mixed ECs, composed of endometrioid (L1CAM(-) ER/PR(+) E-cadherin(+)) and clear-cell/serous (L1CAM(+) ER/PR(-) E-cadherin(-)), both phenotypes were co-expressed. In some of these cases L1CAM was up-regulated at the leading edge of the tumour, where ER/PR and E-cadherin expression were selectively lost. In EC cell lines treated with the epithelial-mesenchymal transition (EMT) inducer TGFbeta1, L1CAM and vimentin were strongly up-regulated, while E-cadherin expression was reduced. The treatment also resulted in an increased expression of the EMT transcription factor Slug and an enhanced cell invasion. Depletion of Slug by siRNA knockdown prevented both L1CAM up-regulation and enhanced cell invasion. According to our analysis, we suggest that L1CAM is a novel marker for EMT in ECs and that L1CAM-typing could identify endometrioid ECs that have type 2-like features and are at high risk for recurrence.

Tsalen- and Tsalpn-Based Nickel Complexes with Two Aldehyde Functionalities as Potential Synthons for Thiophenolate-Containing Di- and Polynucleating Acyclic and Macrocyclic Ligands.

Tsalen- and tsalpn-based nickel complexes with aldehyde functionalities have been prepared (tsalen = N,N'-ethylenebis(thiosalicylideneaminato)(2-) and tsalpn = N,N'-propane-1,3-diyl(thiosalicylideneaminato)(2-)). One of the complexes has been structurally characterized: Ni(pftp) (pftp = N,N-ethylene(6-formyl-4-methyl-2-methyliminatothiophenolato)(2-)) crystallizes in the monoclinic space group C2/c with a = 28.761(7), b = 8.582(2), c = 7.841(4) Å; beta = 98.92(3) degrees, and Z = 4. Ni(pftp) and Ni(eftp) (efpt = N,N-ethylene(6-formyl-4-methyl-2-methyliminatothiophenolato)(2-)) were used as synthons for acyclic and macrocyclic complexes and a prototype of each has been structurally characterized. The Schiff base derivative of Ni(pftp) and 2-(2-aminoethyl)pyridine gives the acyclic complex, Ni(peptp) (peptp =N,N-propane-1,3-diyl(6-(N-(2-ethylpyridyl)iminomethyl)-4-methyl-2-methyliminatothiophenolato)(-)) with the two ethylpyridyl arms furnishing an "open site", which in this complex is vacant, and a "closed site", in which the Ni(2+) is located. Ni(peptp) crystallizes in the monoclinic space group P2(1)/n with a = 10.247(7), b = 21.886(8), c = 15.662(9) Å; beta = 92.58(6) degrees, and Z = 4. Schiff base condensation of Ni(pftp) with diaminopropane gave two different macrocyclic dinickel complexes [L(1)Ni(2)](ClO(4))(2) and L(2)Ni(2). L(1) and L(2) are the 2 + 2 and 4 + 4 macrocycles, respectively, comprising two propylenediamine and two thiocresol units and four propylenediamine and four thiocresol units, respectively. Crystals of L(2)Ni(2) (L(2) = (10,23,36,49-tetramethyl-13,26,39,52-tetramercapto-2,6,15,19,28,32,41,45-octaaza-1,7,14,20,27,33,40,46-octaene[7.7.7.7]metacyclophane) are of poor quality and crystallize in the C2/c space group with a = 31.517(14), b =8.980(2), c = 26.822(12) Å; beta = 117.17(2) degrees, and Z = 4.
