- Studies have demonstrated high rates of mortality in people with proximal femoral fracture and SARS-CoV-2, but there is limited published data on the factors that influence mortality for clinicians to make informed treatment decisions. This study aims to report the 30-day mortality associated with perioperative infection of patients undergoing surgery for proximal femoral fractures and to examine the factors that influence mortality in a multivariate analysis.SettingProspective, international, multicentre, observational cohort study.ParticipantsPatients undergoing any operation for a proximal femoral fracture from 1 February to 30 April 2020 and with perioperative SARS-CoV-2 infection (either 7 days prior or 30-day postoperative).Primary outcome30-day mortality. Multivariate modelling was performed to identify factors associated with 30-day mortality.ResultsThis study reports included 1063 patients from 174 hospitals in 19 countries. Overall 30-day mortality was 29.4% (313/1063). In an adjusted model, 30-day mortality was associated with male gender (OR 2.29, 95% CI 1.68 to 3.13, p<0.001), age >80 years (OR 1.60, 95% CI 1.1 to 2.31, p=0.013), preoperative diagnosis of dementia (OR 1.57, 95% CI 1.15 to 2.16, p=0.005), kidney disease (OR 1.73, 95% CI 1.18 to 2.55, p=0.005) and congestive heart failure (OR 1.62, 95% CI 1.06 to 2.48, p=0.025). Mortality at 30 days was lower in patients with a preoperative diagnosis of SARS-CoV-2 (OR 0.6, 95% CI 0.6 (0.42 to 0.85), p=0.004). There was no difference in mortality in patients with an increase to delay in surgery (p=0.220) or type of anaesthetic given (p=0.787).ConclusionsPatients undergoing surgery for a proximal femoral fracture with a perioperative infection of SARS-CoV-2 have a high rate of mortality. This study would support the need for providing these patients with individualised medical and anaesthetic care, including medical optimisation before theatre. Careful preoperative counselling is needed for those with a proximal femoral fracture and SARS-CoV-2, especially those in the highest risk groups.Trial registration numberNCT04323644

- Uterus transplantation (UTx) can provide a route to motherhood for women with Mayer-Rokitansky-Kuster-Hauser syndrome (MRKHS), a congenital disorder characterized by uterovaginal aplasia, but with functional ovaries. Based on our four successful living-donor transplantations and two resulting births, this analysis presents parameters relevant to standardizing recipient/donor selection, UTx surgery, and postoperative treatment, and their implementation in routine settings. We descriptively analyzed prospectively collected observational data from our four uterus recipients, all with MRKHS, their living donors, and the two newborns born to two recipients, including 1-year postnatal follow-ups. Analysis included only living-donor/recipient pairs with completed donor/recipient surgery. Two recipients, both requiring ovarian restimulation under immunosuppression after missed pregnancy loss in one case and no pregnancy in the other, each delivered a healthy boy by cesarean section. We conclude that parameters crucial to successful transplantation, pregnancy, and childbirth include careful selection of donor/recipient pairs, donor organ quality, meticulous surgical technique, a multidisciplinary team approach, and comprehensive follow-up. Surgery duration and blood vessel selection await further optimization, as do the choice and duration of immunosuppression, which are crucial to timing the first embryo transfer. Data need to be collected in an international registry due to the low prevalence of MRKHS.

- Background: The present survey aims to describe the intensive cardiac care unit organization and admission policies in Europe. Methods: A total of 228 hospitals (61% academic) from 27 countries participated in this survey. In addition to the organizational aspects of the intensive cardiac care units, including classification of the intensive cardiac care unit levels, data on the admission diagnoses were gathered from consecutive patients who were admitted during a two-day period. Admission policies were evaluated by comparing illness severity with the intensive cardiac care unit level. Gross national income was used to differentiate high-income countries (n=13) from middle-income countries (n=14). Results: A total of 98% of the hospitals had an intensive cardiac care unit: 70% had a level 1 intensive cardiac care unit, 76% had a level 2 intensive cardiac care unit, 51% had a level 3 intensive cardiac care unit, and 60% of the hospitals had more than one intensive cardiac care unit level. High-income countries tended to have more level 3 intensive cardiac care units than middle-income countries (55% versus 41%, p=0.07). A total of 5159 admissions were scored on illness severity: 63% were low severity, 24% were intermediate severity, and 12% were high severity. Patients with low illness severity were predominantly admitted to level 1 intensive cardiac care units, whereas patients with high illness severity were predominantly admitted to level 2 and 3 intensive cardiac care units. A policy mismatch was observed in 12% of the patients; some patients with high illness severity were admitted to level 1 intensive cardiac care units, which occurred more often in middle-income countries, whereas some patients with low illness severity were admitted to level 3 intensive cardiac care units, which occurred more frequently in high-income countries. Conclusion: More than one-third of the admitted patients were considered intermediate or high risk. Although patients with higher illness severity were mostly admitted to high-level intensive cardiac care units, an admission policy mismatch was observed in 12% of the patients; this mismatch was partly related to insufficient logistic intensive cardiac care unit capacity.

- Steroid 5 beta-reductase (AKR1D1) plays important role in hepatic bile acid synthesis and glucocorticoid clearance. Bile acids and glucocorticoids are potent metabolic regulators, but whether AKR1D1 controls metabolic phenotype in vivo is unknown. Akr1d1(-/-) mice were generated on a C57BL/6 background. Liquid chromatography/mass spectrometry, metabolomic and transcriptomic approaches were used to determine effects on glucocorticoid and bile add homeostasis. Metabolic phenotypes including body weight and composition, lipid homeostasis, glucose tolerance and insulin tolerance were evaluated. Molecular changes were assessed by RNA-Seq and Western blotting. Male Akr1d1(-/-) mice were challenged with a high fat diet (60% kcal from fat) for 20 weeks. Akr1d1(-/-) mice had a sex-specific metabolic phenotype. At 30 weeks of age, male, but not female, Akr1d1(-/-) mice were more insulin tolerant and had reduced lipid accumulation in the liver and adipose tissue yet had hypertriglyceridemia and increased intramuscular triacylglycerol. This phenotype was associated with sexually dimorphic changes in bile acid metabolism and composition but without overt effects on circulating glucocorticoid levels or glucocorticoid-regulated gene expression in the liver. Male Akr1d1(-/-) mice were not protected against diet-induced obesity and insulin resistance. In conclusion, this study shows that AKR1D1 controls bile acid homeostasis in vivo and that altering its activity can affect insulin tolerance and lipid homeostasis in a sex-dependent manner.

- Objective: To report our experience with the screening and selection of potential recipients and living donors of our uterus transplantation (UTx) program. Design: Part of an observational program. Setting: University hospital. Patient(s): Patients with absolute uterine factor infertility (AUFI). Intervention(s): Screening by e-mail and telephone, selection during surgical consultation, and preoperative investigations according to a multistep procedure for living donation. Main Outcome Measure(s): Age, cause of AUFI, exclusion reasons, and preoperative workup. Result(s): A total of 212 potential recipients expressed interest in participation. Among the 46 potential recipients and 49 directed donors were 4 potential recipients, each with 2 directed donors. Mean (range) age of potential recipients was 29.6 (19–41) years. Of the potential recipients, 39 (84.8%) had congenital AUFI and 7 (17.3%) had acquired AUFI. Ultimately, 15 potential recipients with 16 directed donors were selected for participation, with 1 potential recipient having 2 directed donors. Mean age of included potential recipients was 28.9 (22–35) years, and mean donor age was 51.3 (37–62) years. Fourteen potential recipients (93.3%) had congenital AUFI, and one potential recipient (6.7%) had undergone hysterectomy for obstetric complications. Conclusion(s): The number of potential candidates for UTx is not inconsiderable, with congenital AUFI being the leading cause of AUFI in our cohort. However, our findings highlight that large numbers of AUFI patients need to be screened, considering our exclusion rates were >50%, owing to ABO incompatibility, unavailability of a directed donor, and self-withdrawal. Moreover, meticulous preoperative screening, including in-depth psychological assessment, is mandatory to maximize living donor safety and UTx success. © 2018 American Society for Reproductive Medicine

- Chest pain and acute dyspnoea are frequent causes of emergency medical services activation. The pre-hospital management of these conditions is heterogeneous across different regions of the world and Europe, as a consequence of the variety of emergency medical services and absence of specific practical guidelines. This position paper focuses on the practical aspects of the pre-hospital treatment on board and transfer of patients taken in charge by emergency medical services for chest pain and dyspnoea of suspected cardiac aetiology after the initial assessment and diagnostic work-up. The objective of the paper is to provide guidance, based on evidence, where available, or on experts’ opinions, for all emergency medical services’ health providers involved in the pre-hospital management of acute cardiovascular care.

- Objective: Healthcare professionals (HCPs) are required to assess and train patients in the correct use of inhalers but are often unable to demonstrate correct technique themselves. We sought to assess the level of training required for HCPs to master and maintain device mastery when using two different dry powder inhalers (DPIs). Methods: We conducted a randomized, un-blinded, crossover study in undergraduate HCPs who undertook a six-step training procedure (intuitive use, patient information leaflet, instructional video, individual tuition from expert, then two repeats of individual tuition) for the use of Turbuhaler® (an established device) and Spiromax® (a newer device, reportedly easier to use). Device mastery (absence of errors) was evaluated by expert assessors at each training step. Maintenance of mastery was assessed 4 ± 1 week (visit 2) and 8 ± 2 weeks (visit 3) after initial training (visit 1). Results: Of 516 eligible participants, 113 (22%) demonstrated device mastery prior to training on Spiromax® compared with 20 (4%) on Turbuhaler® (p < 0.001). The median number of training steps required to achieve mastery was 2 (interquartile range [IQR] 2–4) for Spiromax® and 3 (IQR 2–4) for Turbuhaler® (p < 0.001). A higher number of participants maintained mastery with Spiromax® compared with Turbuhaler®, at visits 2 and 3 (64% vs 41% and 79% vs 65%, respectively; p < 0.001). Conclusions: There are significant differences in the nature and extent of training required to achieve and maintain mastery for Spiromax® and Turbuhaler® devices. The implications on clinical practice, device education delivery, and patient outcomes require further evaluation.

Tidskriftsartikel (refereegranskat)abstract
- BACKGROUND: Endothelin (ET) A receptor antagonism causes decreased vasodilation in hypertensive coronary arteries and decreased effects on coronary artery compliance in diabetic patients. METHODS: We investigate the mRNA expression of ET-1, ET(A) and ET(B) receptors, using real time RT-PCR, in biopsies from the internal mammary artery obtained from 49 patients, 18 diabetics and 34 hypertensives, all undergoing coronary artery bypass grafting. RESULTS: Hypertensive patients had higher ET-1 mRNA expression (16438 [8417, 23917]), than normotensive patients (2974 [2283, 18055], p=0.008). Diabetic patients had significantly lower ET(A) receptor levels than non-diabetic patients (455 [167, 1496] vs. 1660 [700, 3190], respectively, p = 0.003). CONCLUSIONS: Multivariate analysis demonstrated that the presence of systemic hypertension was the only independent predictor of log ET(A) receptor expression and log ET-1 expression, while insulin-dependent diabetes was negatively correlated with ET(A) receptor expression. ETB receptor expression was not correlated with any predictor. Systemic hypertension is associated with increased ET-1 and ET(A) receptor mRNA expression, whereas insulin-dependent diabetes down-regulates ET(A) receptor mRNA expression in the internal mammary artery in patients with coronary artery disease undergoing bypass grafting.
