Impact of Simulation-based Mastery Learning on Management of Massive Hemoptysis.

Background: The management of massive hemoptysis is a high-risk, low-volume procedure that is associated with high mortality rates, and pulmonary and critical care medicine (PCCM) fellows often lack training. Simulation-based mastery learning (SBML) is an educational strategy that improves skill but has not been applied to massive hemoptysis management.

Objective: This pilot study aimed to develop a high-fidelity simulator, implement an SBML curriculum, and evaluate the impact on PCCM fellows managing massive hemoptysis.

Screening and treatment of latent tuberculosis in patients with solid tumors and systemic cancer therapy.

Introduction: Tuberculosis is one of the infectious diseases with greater morbidity and mortality worldwide. Cancer causes an important immunosuppression with increased risk of infections. There is an enlarged bidirectional incidence between tuberculosis and cancer, mainly due to latent tuberculosis.

Blue-green neutrophilic inclusion bodies with concurrent liver failure as a predictor of imminent death.

Objectives: Blue-green, birefractory, poorly-defined, cytoplasmic inclusions in some types of leukocytes are an underdiagnosed finding, which composition and clinical significance is not well understood. Inclusions are only found on peripheral blood smear (PBS).

Case Presentation: We report the case of a male with a history of chronic disease (hypertension, obesity, dyslipidemia, and kidney failure) admitted to the emergency room (ER) with shortness of breath, who was later transferred to the intensive care unit (ICU).

[Translated article] A 3D method to estimate the effect of derotational osteotomies over femoral maltorsion.

Introduction And Objectives: Accurate measurement of femoral torsion is essential to diagnosing, correct surgical decision-making, and the preoperative planning of derotational osteotomies in a subgroup of anterior knee pain patients and patellofemoral instability. Several measurement techniques have been described with great variability in the magnitude of the values. Moreover, none of them can predict the effect of rotational osteotomy on the femoral version value.

Anti-drug antibodies in the current management of cancer.

Monoclonal antibodies (mAbs) have become one of the main therapeutic weapons in modern oncology, mainly as targeted therapies, and immune checkpoint inhibitors. The generation of anti-drug antibodies (ADAs) after their administration can alter their pharmacokinetic, pharmacodynamic, efficacy and safety profile causing infusion-related reactions. Several risk factors have been associated with ADAs development, notably host genetics and immune status, comorbidity, concomitant medications, mAbs molecular structure, dose and route of administration.

Anaerobic Digestion for Producing Renewable Energy-The Evolution of This Technology in a New Uncertain Scenario.

Anaerobic digestion is a well-known technology with wide application in the treatment of high-strength organic wastes. The economic feasibility of this type of installation is usually attained thanks to the availability of fiscal incentives. In this review, an analysis of the different factors associated with this biological treatment and a description of alternatives available in literature for increasing performance of the process were provided.

[Rotationplasty in a schoolboy for osteosarcoma: Prosthesis fitting and update].

Introduction: The classical treatment of osteosarcoma used to be ablative surgery. After the appearance of adjuvant chemotherapy, survival in these patients increased, and with it, the number of affected school age children with high growth potential. Hence, reconstructive surgeries are currently proposed instead of conventional bone resections due to greater limb preservation and better functional status than those achieved with conventional amputations.

Performance evaluation of a small-scale digester for achieving decentralised management of waste.

The performance of a small-scale prototype digestion plant (7.2 m working volume) intended for decentralised operation was evaluated considering energy efficiency and technical suitability for biogas valorisation in producing electrical and thermal energy. The digester operated in recirculation mode to enhance organic matter conversion and improve volatile solid degradation.

Anaerobic digestion of fourth range fruit and vegetable products: comparison of three different scenarios for its valorisation by life cycle assessment and life cycle costing.

Changes in consumer demand due to preferences for a healthier lifestyle have led to a new market offering fruit and salad products ready to eat. This affects the agro-industrial sector and the characteristic of waste streams generated having the organic fraction higher quality and representing a new opportunity of valorisation. This study experimentally evaluated the digestion of wastes derived from the fourth range product sector.

[Posturographic and oculomotor findings in the first 24 hours after whiplash].

Introduction And Objectives: Instability is a frequent symptom after whiplash (WL) with alterations in postural control in chronic phases. The main objective of our study was to evaluate if there were objective alterations in postural control in the acute phases after a WL, as well as to determine the presence or absence of oculomotor alterations in early phases.

Material And Methods: A posturographic study was carried out using the NedSVE/IBV system, as well as an oculomotor assessment, in a sample of 44 patients with WL in the first 24h after the accident.

Integrating anaerobic digestion and pyrolysis for treating digestates derived from sewage sludge and fat wastes.

The coupling of biological and thermal technologies allows for the complete conversion of wastes into energy and biochar eliminating the problem of sludge disposal. The valorisation of fatty residues as co-substrate in a mesophilic digester of a wastewater treatment plant was studied considering an integrated approach of co-digestion and pyrolysis. Four digested samples obtained from co-digestion of sewage sludge and butcher's fat waste were studied by thermogravimetric analysis.

Effect of char addition on anaerobic digestion of animal by-products: evaluating biogas production and process performance.

The effect of char addition on the digestion of animal by-products was evaluated as a way for enhancing the performance of the process. Two different types of carbonaceous materials were tested as carbon conductive elements to improve biological treatment. One was derived from a torrefaction process intended for increasing the energy density of lignocellulosic biomass, and the other was obtained from a hydrothermal carbonisation process.

[Comparison between extracorporeal shockwave therapy and radial pressure wave therapy in plantar fasciitis].

Objective: Plantar fasciitis is a common cause of heel pain. The aetiology of this condition remains unclear. Patients typically have pain upon palpation of the medial plantar calcaneal region.

Motor deficit in the puerperium. Is neuroaxial analgesia the most frequent cause?

Motor deficits of lower limbs during pregnancy and the puerperium are relatively frequent. They are usually attributed to complications which are associated with neuroaxial techniques performed by the anesthesiologist. But there are other possible causes, such as transient osteoporosis of the hips.

Phase 1b trial of docetaxel, prednisone, and pazopanib in men with metastatic castration-resistant prostate cancer.

Background: Docetaxel prednisone is a standard of care for men with metastatic castration-resistant prostate cancer (mCRPC), and plasma vascular endothelial growth factor (VEGF) levels are a poor prognostic factor in this population; therefore, we evaluated the combination of docetaxel prednisone with pazopanib, an oral VEGF receptor inhibitor, for safety and preliminary efficacy.

Methods: This is a two-site phase 1b Department of Defense Prostate Cancer Clinical Trials Consortium trial of docetaxel, prednisone, and pazopanib once daily and ongoing androgen deprivation therapy and prophylactic pegfilgrastim in men with mCRPC. The primary endpoint was safety and the determination of a maximum tolerated dose (MTD) through a dose-escalation and expansion design; secondary endpoints included progression-free and overall survival (OS), prostate specific antigen (PSA) declines, radiographic responses, and pharmacokinetic and plasma angiokine biomarker analyses.

Prospective International Randomized Phase II Study of Low-Dose Abiraterone With Food Versus Standard Dose Abiraterone In Castration-Resistant Prostate Cancer.

Purpose Abiraterone acetate (AA) is a standard of care for metastatic castration-resistant prostate cancer (CRPC). Despite a large food effect, AA was administered under fasting conditions in its pivotal trials. We sought to test the hypothesis that low-dose AA (LOW; 250 mg with a low-fat meal) would have comparable activity to standard AA (STD; 1,000 mg fasting) in patients with CRPC.

Phase Ib Trial of Cabazitaxel and Tasquinimod in Men With Heavily Pretreated Metastatic Castration Resistant Prostate Cancer (mCRPC): The CATCH Trial.

Background: Tasquinimod is an immunomodulating and anti-antiangiogenic oral agent with anti-prostate cancer activity in preclinical studies and in clinical trials of men with metastatic castration resistant prostate cancer (mCRPC), including single agent activity and in combination with taxanes. We sought to identify the maximum tolerated dose (MTD) and recommended phase 2 dose (RP2D) of tasquinimod in combination with cabazitaxel and prednisone in men with chemorefractory mCRPC.

Methods: Men with mCRPC who had failed prior docetaxel chemotherapy received cabazitaxel 25 mg/m every 3 weeks with oral tasquinimod at 1 of 3 escalating dose levels (0.

New biofuel alternatives: integrating waste management and single cell oil production.

Concerns about greenhouse gas emissions have increased research efforts into alternatives in bio-based processes. With regard to transport fuel, bioethanol and biodiesel are still the main biofuels used. It is expected that future production of these biofuels will be based on processes using either non-food competing biomasses, or characterised by low CO₂ emissions.
