Objective: To report the incidence of venous thromboembolism (VTE) after nephrectomy in Denmark and explore associated risk factors. Materials and Methods: A nationwide population-based retrospective cohort study was performed. All nephrectomies from January 2010 to August 2018 were assessed for postoperative VTE events. Univariable and multivariable analyses were used to evaluate the odds ratio (OR) of clinical variables’ effect on postoperative VTEs, within 4 weeks and 4 months after nephrectomy. Results: In 5213 nephrectomized patients, postoperative VTE incidence was 1% and 2% within 4 weeks and 4 months, respectively. Multivariable analyses revealed that predictors of postoperative VTE within 4 months were: open nephrectomy (OR 2.5, P =.001), history of VTE (OR 13.3, P

Episodic breathlessness is frequent in palliative cancer patients. Opioids are the only pharmacological agents with sufficient evidence in treatment. In Denmark, the main recommendation is red morphine drops (RMD), an off-label solution of morphine, ethanol, and red color (cochenille) described since 1893 (Pharmacopoea Danica). In 2015, the Danish Medicines Agency increased focus on off-label medicines and recommended registered morphine drops without ethanol instead. However, our palliative patients told us that RMD was better. For that reason, we conducted a clinical trial to clarify any perceived difference between the two types of drops. We conducted a randomized, double blinded, crossover trial. Patients were asked to perform standardized activity (2-min walk) aiming to provoke breathlessness. Primary endpoint (breathlessness NRS) and secondary endpoints (saturation, pulse, respiratory frequency) were measured before (t = 0) and after test medicine at t = 1, t = 3, t = 5, t = 10, and t = 20 min. After 2–4 days (washout period), the patients repeated the test, receiving the alternative drops in a blinded setup (crossover). In the first 3 min, the relative drop in breathlessness for morphine drops with ethanol (RMD) was significant more than for morphine drops without ethanol. We found no significant difference in secondary endpoints. A conclusion could be that ethanol might facilitate morphine absorption in the mouth. Our results needs further research of opioid absorption in the mouth as well as trials, testing morphine vs. more lipophilic opioids. The RMD drops are cheap, easy to use, and noninvasive and keep the patient independent of health care professionals.

Previous studies suggest an increased cancer risk in hypertension. Patients with hypertensive nephropathy have not been studied. A national registry study was performed to assess the presence and size of this association. Clinical data and cancer diagnoses for all patients with biopsy-proven hypertensive nephropathy between 1985 and 2015 in Denmark were extracted from four national registries and compared with age- and sex-adjusted national cancer rates. The risk of cancer was twice the background population. It was raised for renal cancer (odds ratio 10.4), myeloma (13.2), skin cancer (7.9), and other/unspecified (1.8). No increase in incidence was seen until 1 year before renal biopsy and then rose rapidly. It was again normal 5 years after biopsy. Hypertensive nephropathy is associated with an increased risk of myeloma, skin, renal, and other cancers. Screening of patients with hypertensive nephropathy, in the presence of reduced renal function or significant proteinuria, may be indicated.

BackgroundWe tested the joint hypotheses that both perineural and systemic dexmedetomidine prolong the duration of an ulnar nerve block (UNB) compared with ropivacaine alone and that systemic dexmedetomidine is noninferior compared with perineural dexmedetomidine in block prolongation.MethodsWe performed bilateral UNBs in 22 healthy volunteers on two separate days. On the first day, each arm was randomized to either 4 mL ropivacaine 5 mg/mL+1 mL dexmedetomidine 100 µg/mL (Perineural) or 4 mL ropivacaine 5 mg/mL+1 mL saline (Systemic). On the subsequent treatment day, each arm was randomized to 1 mL of saline plus 4 mL of ropivacaine at either 7.5 mg/mL(HiRopi) or 5 mg/mL (NoDex). The primary outcome measure was the duration of sensory block assessed by mechanical discrimination.ResultsMean sensory block duration was longer in both the Perineural (14.4 hours, 95% CI 13.1 to 15.6) and Systemic treatments (9.2 hours, 95% CI 8.6 to 9.8) compared with the NoDex treatment (7.1 hours, 95% CI 6.6 to 7.6) (pConclusionsAdding dexmedetomidine perineurally to ropivacaine doubles the duration of an UNB. Systemic dexmedetomidine also prolongs the duration of UNB, but has less of an effect compared with the perineural route.Trial registration numberNCT03222323.

Background The objective of this trial is to optimize the transmuscular quadratus lumborum (TQL) block, by investigating the minimal effective volume (MEV90 ) of ropivacaine 0.75% for single-shot TQL block in percutaneous nephrolithotomy (PNL) patients. Methods This double-blind, randomized and controlled dose-finding trial is based on a biased coin up-and-down sequential design, where the volume of local anaesthetic administered to each patient depends on the response from the previous one. Investigating the TQL block, the first patient recruited receives 20 ml ropivacaine 0.75% preoperatively. In case of block failure, the next patient will receive the same volume with an increment of 2 ml. Given a successful block for the first patient, the next patient will be randomized to either a lower volume (previous volume with a reduction of 2 ml), or the same volume as the previous patient. The respective probabilities being b = 0.11 for a reduced volume and 1-b = 0.89 for the same volume. Block success is defined as patient reported pain score numeric rated scale (NRS) ≤3 (0-10/10) 30 minutes after arrival in the post anaesthesia care unit (PACU). The NRS pain score is our primary and only outcome for block success. A minimum of 25 eligible patients are needed to achieve precise estimation of MEV90 with narrow 95% confidence intervals derived by bootstrapping. Discussion Recruiting will begin June 2020 and is expected to finish November 2020. Data analysis will be performed at interims during and after the study. Results will be published in an international peer-reviewed medical journal.

Background The European Resuscitation Council Guidelines 2015 recommend bystanders to activate their mobile phone speaker function, if possible, in case of suspected cardiac arrest. This is to facilitate continuous dialogue with the dispatcher including (if required) cardiopulmonary resuscitation instructions. The aim of this study was to measure the bystander capability to activate speaker function in case of suspected cardiac arrest. Method In 87 days, a systematic prospective registration of bystander capability to activate the speaker function, when cardiac arrest was suspected, was performed. For those asked, “can you activate your mobile phone’s speaker function”, audio recordings were examined and categorized into groups according to the bystanders capability to activate speaker function on their own initiative, without instructions, or with instructions from the emergency medical dispatcher. Time delay was measured, in seconds, for the bystanders without pre-activated speaker function. Results 42.0% (58) was able to activate the speaker function without instructions, 2.9% (4) with instructions, 18.1% (25) on own initiative and 37.0% (51) were unable to activate the speaker function. The median time to activate speaker function was 19 s and 8 s, with and without instructions, respectively. Conclusion Dispatcher assisted cardiopulmonary resuscitation with activated speaker function, in cases of suspected cardiac arrest, allows for continuous dialogue between the emergency medical dispatcher and the bystander. In this study, we found a 63.0% success rate of activating the speaker function in such situations.

BackgroundElective cesarean section (ECS) can cause moderate to severe pain that often requires opioid administration. To enhance maternal recovery, and promote mother and baby interaction, it is important to reduce postoperative pain and opioid consumption. Various regional anesthesia techniques have been implemented to improve postoperative pain management following ECS. This study aimed to investigate the efficacy of bilateral ultrasound-guided transmuscular quadratus lumborum (TQL) block on reducing postoperative opioid consumption following ECS.MethodsA randomized double-blind trial with concealed allocation was conducted in 72 parturients who received bilateral TQL block with either 30 mL ropivacaine 0.375% or saline. TQL block injectate was deposited in the interfascial plane between the quadratus lumborum and psoas major muscles, posterior to the transversalis fascia. Primary outcome was opioid consumption, which was recorded electronically. Pain scores and time to first opioid request were also evaluated.ResultsOpioid consumption (oral morphine equivalents, OME) was significantly reduced in group ropivacaine (GRO) in the first 24 hours compared with group saline (65 mg OME vs 94 mg OME) with a mean difference of 29 mg OME; 95% CI 3 to 55, pConclusionsBilateral TQL block significantly reduced 24 hours’ opioid consumption. Further, we observed significant prolongation in time to first opioid, and significant reduction of pain during the first 6 postoperative hours.

INTRODUCTION: Greenland has one of the highest prevalences of otitis media in the world. However, access to ear specialists throughout Greenland is limited and currently there are no national guidelines for treatment or prevention. Tele-otoscopy may be beneficial in optimizing diagnosis and treatment. The smartphone otoscopy device, Cupris®, has previously been validated when used by medical doctors on a population primarily consisting of adults. In this study we evaluated the usability of the Cupris® otoscope when used by local health care workers with different levels of training and education, examining children aged 1-6 years.METHODS: We conducted a cross-sectional study in three Greenlandic towns. Health care personnel were asked to perform video-otoscopy on children contacting the health clinic for any reason. The videos were sent for remote evaluation by three ear specialists who rated the videos on a five-point Likert scale and provided information on challenges with the videos. The dichotomous outcome "not useful/useful" was defined as 1-3 and 4-5 on the Likert scale, respectively.RESULTS: In total, 142 videos were recorded on 84 patients. Mean proportion of useful videos was 18.1%, with a modified Fleiss' Kappa interrater agreement coefficient of 0.67 95% CI [0.57-0.76] corresponding to substantial agreement among the three raters.CONCLUSIONS: In this study the usefulness of the Cupris® TYM otoscope did not prove to be sufficient with the presented instruction in the hands of local health care workers when examining Greenlandic children. Focus on training and education of local health personnel is crucial and warranted before advantageous implementation for non-specialist health care workers can be expected.

Background: Percutaneous nephrolithotomy (PNL) is associated with severe postoperative pain. The current study aimed to investigate the analgesic efficacy of transmuscular quadratus lumborum (TQL) block for patients undergoing PNL surgery. Methods: Sixty patients were enrolled in this single centre study. The multimodal analgesic regime consisted of oral paracetamol 1 g and i.v. dexamethasone 4 mg before surgery and i.v. sufentanil 0.25 μg kg−1 30 min before emergence. After operation, patients received paracetamol 1 g regularly at 6 h intervals. Subjects were allocated to receive a preoperative TQL block with either ropivacaine 0.75%, 30 ml (intervention) or saline 30 ml (control). Primary outcome was oral morphine equivalent (OME) consumption 0–6 h after surgery. Secondary outcomes were OME consumption up to 24 h, pain scores, time to first opioid, time to first ambulation, and hospital length of stay. Results were reported as mean (standard deviation) or median (inter-quartile range). Results: Morphine consumption was lower in the intervention group at 6 h after surgery (7.2 [8.7] vs 90.6 [69.9] mg OME, P

Purpose To investigate if early mobilization after open reduction internal fixation of distal radius fractures improved the functional outcome. We hypothesized that early mobilization would lead to improved patient-reported outcome. Second, we aimed to assess whether early mobilization increased the risk of postoperative implant loosening or breakage. Methods All included patients were treated with a volar locking plate. After surgery, patients were randomized to either early mobilization (E-MOB) with a removable orthosis (wrist lacer) and daily wrist exercises or to late mobilization (L-MOB) with a standard dorsal plaster cast for 2 weeks and, after that, a removable orthosis and exercises. We measured all patients at 4 weeks and at 3, 6, and 12 months after surgery. At each postoperative visit, we measured range of motion and grip strength and patients filled out the Disabilities of the Arm, Shoulder, and Hand (DASH) questionnaire. Radiographic implant loosening or breakage was assessed 14 days after surgery. Results A total of 47 patients were allocated to E-MOB and 48 to L-MOB. The DASH score improved substantially throughout the follow-up period with no significant differences between the 2 groups at any time point. Implant loosening and fracture redisplacement was observed in 1 patient in the E-MOB group. Range of motion and grip strength were similar between the 2 groups at all time points. Conclusions Early mobilization after surgical treatment of distal radius fractures does not lead to improved patient-reported outcome. Type of study/level of evidence Therapeutic I.

Psychological distress is a trans-diagnostic feature of mental suffering closely associated with mental disorders. Kessler's 10-item Psychological Distress Scale (K10), a scale with sound psychometric properties, is widely used in epidemiological studies.To translate and investigate whether K10 is a reliable and valid rating scale for the measurement of psychological distress in a Danish population.The translation was carried out according to official WHO translation guidelines. A sample of 100 subjects was included, 54 patients from the regional Mental Health Service (MHS) and 46 subjects with no psychiatric history. All participants were assessed with a psychiatric diagnostic interview (MINI) and handed out K10. Concurrent validity was assessed by WHO Well-being Index (WHO-5). Correlation matrix analysis was conducted for the full sample and receiver operating characteristic (ROC) curves for discriminating mental health service affiliation.Mean K10 scores differed, with decreasing levels, between inpatients and outpatient in MHS and the subjects with no psychiatric history. Factor analysis confirmed a unidimensional structure, and Cronbach's alpha and Omega showed excellent internal reliability. AUC for the K10 ROC curves showed excellent sensitivity (0.947 [0.900-0.995]), accurately differentiating mental health from non-mental health patients.The Danish K10 has the same strong internal reliability as the original English version, and scores differ between psychiatric patients in outpatient and emergency ward settings.The Danish K10 translation is authorized and freely available for download at https://www.hcp.med.harvard.edu/ncs/k6_scales.php . The utility as an instrument for clinical screening in a mental healthcare setting is supported.
