- Advances in FAI Imaging: a Focused ReviewPublication . Mascarenhas, V; Caetano, A; Dantas, P; Rego, PPurpose of review: Femoroacetabular impingement (FAI) is one of the main causes of hip pain in young adults and poses clinical challenges which have placed it at the forefront of imaging and orthopedics. Diagnostic hip imaging has dramatically changed in the past years, with the arrival of new imaging techniques and the development of magnetic resonance imaging (MRI). This article reviews the current state-of-the-art clinical routine of individuals with suspected FAI, limitations, and future directions that show promise in the field of musculoskeletal research and are likely to reshape hip imaging in the coming years. Recent findings: The largely unknown natural disease course, especially in hips with FAI syndrome and those with asymptomatic abnormal morphologies, continues to be a problem as far as diagnosis, treatment, and prognosis are concerned. There has been a paradigm shift in recent years from bone and soft tissue morphological analysis towards the tentative development of quantitative approaches, biochemical cartilage evaluation, dynamic assessment techniques and, finally, integration of artificial intelligence (AI)/deep learning systems. Imaging, AI, and hip preserving care will continue to evolve with new problems and greater challenges. The increasing number of analytic parameters describing the hip joint, as well as new sophisticated MRI and imaging analysis, have carried practitioners beyond simplistic classifications. Reliable evidence-based guidelines, beyond differentiation into pure instability or impingement, are paramount to refine the diagnostic algorithm and define treatment indications and prognosis. Nevertheless, the boundaries of morphological, functional, and AI-aided hip assessment are gradually being pushed to new frontiers as the role of musculoskeletal imaging is rapidly evolving.
- Sex-Specific Outcome Disparities in Very Old Patients Admitted to Intensive Care Medicine: a Propensity Matched AnalysisPublication . Wernly, B; Romano Bruno, R; Kelm, M; Boumendil, A; Morandi, A; Andersen, F; Artigas, A; Finazzi, S; Cecconi, M; Christensen, S; Faraldi, L; Lichtenauer, M; Muessig, J; Marsh, B; Moreno, R; Oeyen, S; Öhman, C; Bollen Pinto, B; Soliman, I; Szczeklik, W; Niederseer, D; Valentin, A; Watson, X; Leaver, S; Boulanger, C; Walther, S; Schefold, J; Joannidis, M; Nalapko, Y; Elhadi, M; Fjølner, J; Zafeiridis, T; De Lange, D; Guidet, B; Flaatten, H; Jung, CFemale and male very elderly intensive patients (VIPs) might differ in characteristics and outcomes. We aimed to compare female versus male VIPs in a large, multinational collective of VIPs with regards to outcome and predictors of mortality. In total, 7555 patients were included in this analysis, 3973 (53%) male and 3582 (47%) female patients. The primary endpoint was 30-day-mortality. Baseline characteristics, data on management and geriatric scores including frailty assessed by Clinical Frailty Scale (CFS) were documented. Two propensity scores (for being male) were obtained for consecutive matching, score 1 for baseline characteristics and score 2 for baseline characteristics and ICU management. Male VIPs were younger (83 ± 5 vs. 84 ± 5; p < 0.001), less often frail (CFS > 4; 38% versus 49%; p < 0.001) but evidenced higher SOFA (7 ± 6 versus 6 ± 6 points; p < 0.001) scores. After propensity score matching, no differences in baseline characteristics could be observed. In the paired analysis, the mortality in male VIPs was higher (mean difference 3.34% 95%CI 0.92-5.76%; p = 0.007) compared to females. In both multivariable logistic regression models correcting for propensity score 1 (aOR 1.15 95%CI 1.03-1.27; p = 0.007) and propensity score 2 (aOR 1.15 95%CI 1.04-1.27; p = 0.007) male sex was independently associated with higher odds for 30-day-mortality. Of note, male gender was not associated with ICU mortality (OR 1.08 95%CI 0.98-1.19; p = 0.14). Outcomes of elderly intensive care patients evidenced independent sex differences. Male sex was associated with adverse 30-day-mortality but not ICU-mortality. Further research to identify potential sex-specific risk factors after ICU discharge is warranted.Trial registration: NCT03134807 and NCT03370692; Registered on May 1, 2017 https://clinicaltrials.gov/ct2/show/NCT03370692 .
- Nivolumab-Induced Seronegative EncephalitisPublication . Cabral, G; Ladeira, F; Gil, NImmune checkpoint inhibitors (ICIs) have emerged as a new therapeutic tool for numerous types of cancer. Neurological complications have been reported in 1% of patients who have undergone checkpoint inhibition therapy. ICIs-induced encephalitides occur in 0.1-0.2% of patients within weeks after ICIs initiation; are usually seronegative and have nonspecific changes on imaging, CSF and electroencephalogram (EEG) studies. Early recognition and prompt treatment are important to prevent significant morbidity and mortality. We present a case of nivolumab-induced encephalitis with very subtle clinical symptoms and full recovery following ICIs suspension and steroids.
- Lesão Renal Aguda Após Implantação Percutânea de Válvula Aórtica: Incidência, Fatores de Risco e Impacto na MortalidadePublication . Martins, A; Castro, L; Fragata, IIntroduction: Acute kidney injury is a frequent complication after transcatheter aortic valve implantation with great impact on morbidity and mortality. It is important to identify modifiable risk factors in order to develop preventive strategies. The aim of the study is to determine acute kidney injury incidence, risk factors and impact in patients that underwent transcatheter aortic valve implantation. Material and methods: Retrospective study in 149 consecutive patients that underwent transcatheter aortic valve implantation at Santa Marta Hospital. The data was collected from the periprocedural records and stratified by the occurrence of acute kidney injury according to the AKIN classification. Results: A total of 149 patients, 43.0% male with median age 82.00 [77.50 - 85.00] years were included in the study. Incidence of acute kidney injury was 14.8% (n = 22). Female patients (OR 0.138, CI 95%; 0.022 - 0.854; p = 0.033) had a higher risk of that complication. Patients with acute kidney injury had longer hospitalizations (OR 1.043, CI 95%; 1.001 - 1.085; p = 0.043); acute kidney injury was associated with increased 30 day mortality (OR 13.889, 95% CI; 2.371 - 81.363; p = 0.004). Discussion: Acute kidney injury is associated with preprocedural variables and is a determinant of morbimortality. However, the retrospective character and the reduced sample size didn't allow the determination of the precise weight of each factor. Conclusion: Acute kidney injury is a complication after transcatheter aortic valve implantation which played a significant role in morbimortality justifying its prevention.
- Evolution of Resting Energy Expenditure, Respiratory Quotient, and Adiposity in Infants Recovering from Corrective Surgery of Major Congenital Gastrointestinal Tract Anomalies: A Cohort StudyPublication . Pereira-da-Silva, L; Barradas, S; Moreira, AC; Alves, M; Papoila, AL; Virella, D; Cordeiro-Ferreira, GThis cohort study describes the evolution of resting energy expenditure (REE), respiratory quotient (RQ), and adiposity in infants recovering from corrective surgery of major congenital gastrointestinal tract anomalies. Energy and macronutrient intakes were assessed. The REE and RQ were assessed by indirect calorimetry, and fat mass index (FMI) was assessed by air displacement plethysmography. Longitudinal variations over time are described. Explanatory models for REE, RQ, and adiposity were obtained by multiple linear regression analysis. Twenty-nine infants were included, 15 born preterm and 14 at term, with median gestational age of 35.3 and 38.1 weeks and birth weight of 2304 g and 2935 g, respectively. In preterm infants, median REE varied between 55.7 and 67.4 Kcal/kg/d and median RQ increased from 0.70 to 0.86-0.92. In term infants, median REE varied between 57.3 and 67.9 Kcal/kg/d and median RQ increased from 0.63 to 0.84-0.88. Weight gain velocity was slower in term than preterm infants. FMI, assessed in a subset of 15 infants, varied between a median of 1.7 and 1.8 kg/m2 at term age. This low adiposity may be related to poor energy balance, low fat intakes, and low RQ¸ that were frequently recorded in several follow-up periods.
