Reducing Shoulder Complaints in Employees with High Occupational Shoulder Exposures: A Cluster-Randomised Controlled Study (The Shoulder-Café Study).

PURPOSE: To evaluate if a group-based Shoulder-Café intervention could reduce shoulder complaints more effectively than an individual-based control intervention in employees with shoulder complaints and high occupational shoulder exposures. METHODS: A cluster-randomised controlled study of 109 participants from 60 companies in Central Denmark Region. Companies were randomised and allocated to either Shoulder-Café or control intervention. Participants in both interventions received a pamphlet on home-based shoulder exercises and a pamphlet with general information on reducing occupational shoulder exposures. They also had their occupational shoulder exposures assessed. Shoulder-Café participants additionally received three café-meetings with casual discussion, clinical shoulder evaluation, education about shoulder anatomy and occupational shoulder exposures, supervised exercises, workplace-oriented counselling, and an optional workplace visit. The primary outcome measure was the Oxford Shoulder Score (OSS) at 6-month follow-up. Secondary outcome measures were the OSS at 12 months, Fear-Avoidance Beliefs Questionnaire - Physical Activity at 6 and 12 months, and Patients' Global Impression of Change at 6 months. The study also included seven supplementary outcome measures. RESULTS: Both groups improved from baseline to 6 months with respect to the primary outcome (P < 0.01). No group differences were found for the primary outcome (mean difference (MD) [95% confidence interval]: 0.3 [- 1.6; 2.2]) or secondary outcomes. The supplementary outcomes "felt informed about handling shoulder complaints" and "felt informed about reducing occupational exposures" at 6 months, and "Patients' Global Impression of Change" and "overall satisfaction" at 12 months favoured the Shoulder-Café intervention. CONCLUSION: The Shoulder-Café intervention did not reduce shoulder complaints more effectively than the control intervention. TRIAL REGISTRATION: The trial was registered at Clinicaltrials.gov on 19 May 2017 (ID: NCT03159910).

Ambulatory blood pressure as predictor of preeclampsia in diabetic pregnancies with respect to urinary albumin excretion rate and glycemic regulation.

BACKGROUND: Twenty-four-hour ambulatory blood pressure was evaluated as a predictor of preeclampsia in women with insulin-dependent diabetes mellitus with respect to urinary albumin excretion rate and glycemic regulation. METHODS: One hundred and fifty-one women with insulin-dependent diabetes mellitus were consecutively recruited from the outpatient maternity ward for 24 hour ambulatory blood pressure measurement with a portable monitor (SpaceLab 90207). Blood pressure was measured three times during pregnancy and once after delivery. Evaluation was performed with receiver-operator-characteristics curves in primiparous women. Stratified analysis and multiple regression was applied with respect to urinary albumin excretion rate, HbA1c, age, duration of diabetes mellitus, uric acid, and BMI. RESULTS: The incidence of preeclampsia was significantly associated with increasing urinary albumin excretion rate, primiparity, and ambulatory blood pressure. Ambulatory blood pressure was associated with HbA1c throughout pregnancy adjusted for urinary albumin excretion rate. The ambulatory blood pressure was higher from first trimester throughout pregnancy in women developing preeclampsia compared to women who did not have preeclampsia. The best sensitivity and specificity for predicting preeclampsia in primiparous women were at cut-off values of systolic and diastolic day ambulatory blood pressure above 122 and 74 mmHg, respectively. The relative risk of preeclampsia was significantly higher when ambulatory blood pressure was above the cut-off values and increased further with higher urinary albumin excretion rate. CONCLUSIONS: The relationship between ambulatory blood pressure and preeclampsia is not confined to women with macroalbuminuria but is also present in women with normo- and microalbuminuria. Poor glycemic control and increased urinary albumin excretion rate is associated with preeclampsia when ambulatory blood pressure is above cut-off values of 122/74 mmHg (systole/diastole). Ambulatory blood pressure is a reliable measurement for prediction of preeclampsia in primiparous women with insulin-dependent diabetes mellitus.

Circumstances and outcome of roller skating accidents (RSA) and the use of protective gear was surveyed. During 1.1.95-31.12.98 a questionnaire survey was conducted among subjects involved in RSA and combined with data from the A + E dept. A major increase in RSA was reported during this four year study period. A total of 399 injuries were recorded, of which 178 had wrist-related injuries and of which 125 had fractures. RSA accounted for a total of 17% of all wrist fractures among 11-15 year-old teenagers. In 1998 this percentage had increased to 28%. The median age for wrist fracture was 12.6 years. Of the 325 injured who answered the questionnaire, 67% (mostly children) did not use any kind of protective gear, and only 64% had purchased such gear. Beginners and experienced skaters showed differences regarding characteristics and risk profile. Education in non-risk behaviour and the recommendation of wrist guards seems permissible, as the number of injured is suspected to be steadily growing among teenagers.

Ischemia and reperfusion of the porcine myocardium: effect on collagen.

We studied the effect of acute myocardial infarction and late reperfusion on myocardial collagen in a closed chest porcine model, to investigate if any collagen degradation could be detected in blood samples and myocardium. Sixteen 60-80 kg pigs were used with six animals serving as controls and 10 submitted to ischemia-reperfusion. In the ischemia-reperfusion group the left anterior descending coronary artery was occluded for 6 h by inflation of a percutaneous transluminal coronary angioplasty balloon followed by reperfusion for 3 h. Blood samples were taken from the aorta and the coronary sinus and analyzed for creatine kinase and collagen degradation products, i.e. the N-terminal propeptide of procollagen type III (PIIINP) and C-terminal pyridinoline cross-linked telopeptide of collagen type I (ICTP). Myocardial tissue samples were analyzed for content of hydroxyproline, collagen volume fraction and amount of extractable PIIINP/dry weight. Transmission electron microscopy of biopsies was performed to evaluate myocytes and collagen structure outside and within the infarct zone. Creatine kinase showed a statistically significant increase during ischemia and reperfusion but we found no evidence of release of collagen degradation products either during ischemia or reperfusion compared with control. Myocardial content of hydroxyproline, collagen volume fraction and extractable PIIINP/dry weight did not differ between groups. Transmission electron microscopy of biopsies from the infarct zone showed myocyte damage but no visible evidence of collagen degradation when photos were evaluated blindly. In this porcine model of acute myocardial infarction and late reperfusion no release of collagen degradation products from the myocardium or any decrease in or damage to myocardial collagen was detected.

Escherichia vulneris in a Danish soccer wound.

Escherichia vulneris was isolated from an infected soccer wound, a finding which has not apparently been described in Europe before, but by questioning Danish clinical microbiological laboratories a further 12 cases were discovered. Treatment with simple debridement and cefuroxime quickly eradicated the bacteria in our case.

Renal growth during pregnancy in insulin-dependent diabetic women. A prospective study of renal volume and clinical variables.

Kidney volume was measured during pregnancy in insulin-dependent diabetic women by an ultrasound technique and prognostic value of these measurements evaluated. A prospective study was performed on 87 pregnant women with insulin-dependent diabetes attending the maternity clinic of Aarhus Kommunehospital. Patients with proliferative retinopathy alone, hydronephrosis, or nephrotic syndrome were excluded. The patients were grouped according to onset and duration of diabetes and to vascular lesions; group I (n = 35, White class B+C), group II (n = 11, White class D0), group III (n = 26, White class D+), and group IV (n = 15, White class F+F/R). The patients visited the hospital every 2 weeks during pregnancy for general obstetric and glycaemic control and blood sampling. The volume of both kidneys was measured by a computerized nephrosonograph during the three terms of pregnancy, the puerperium and 4 months postpartum. The kidney volume increased significantly in all four groups from first to third trimester. In the third trimester the kidney volumes were 375 +/- 68 ml (I), 341 +/- 50 ml (II), 362 +/- 63 ml (III), and 343 +/- 54 ml (IV). The kidney volume in the third trimester was positively correlated with creatinine clearance (r = 0.33, P < 0.01) and inversely correlated with creatinine in serum (r = -0.27, P = < 0.02). Total kidney volume decrease (in percent) defined as the difference of maximal volume and value at 4 months postpartum was inversely correlated to albuminuria in the third trimester (r = -0.25, P < 0.05) and vascular lesions of the patients: (mean +/- SEM) 37 +/- 4% (I), 25 +/- 7% (II), 19 +/- 5% (III), and 11 +/- 7% (IV), P < 0.01. In the puerperium, kidney volume decreased significantly from third trimester in groups I, II, and III, whereas we observed no change in group IV. Six of 15 women in groups II and III with kidney volume < 300 ml and normoalbuminuria in the first trimester developed persistent microalbuminuria after pregnancy (P < 0.02). The renal volume in insulin-dependent diabetic women increases significantly during pregnancy and is inversely related to the vascular lesions of the patients. The decrease in renal volume after pregnancy is related to the albuminuria at the end of pregnancy. Women with longstanding diabetes, White class D (= groups II+III), and kidney volume < 300 ml in the first trimester have a high risk of developing permanent microalbuminuria after pregnancy.
