Large-scale real-life analysis of survival and usage of therapies in multiple myeloma.

Survival in multiple myeloma has improved significantly in recent years, especially in young patients. We reviewed the evolution of the survival of patients with MM in three groups based on age at MM diagnosis over three time periods between 1999 and 2020 at our 12 de Octubre Hospital institution (H12O). Then, to confirm our results, we used data from TriNetx, a global health research platform that includes patients from Europe to US. Finally, we analysed differences in the patterns of treatment between networks across the world. Kaplan‒Meier analysis was used to estimate survival probabilities, and between-group differences were tested using the log-rank test and hazard ratio. For patients from H12O, the median OS was 35.61, 55.59 and 68.67 months for the 1999-2009, 2010-2014 and 2015-2020 cohorts, respectively (p = 0.0001). Among all patients included in the EMEA network, the median OS was 20.32 months versus 34.75 months from 1999-2009 versus 2010-2014. The median OS from the 2010-2014 versus 2015-2020 time cohorts was 34.75 months versus 54.43 months, respectively. In relation to the US cohort, the median OS from before 2010 versus 2010-2014 was not reached in either time cohort and neither when comparing the 2010-2014 versus 2015-2019 time cohorts. Bortezomib is the most commonly used drug in the EMEA cohort, while lenalidomide is the most commonly used drug in the US cohort. This large-scale study based on real-world data confirms the previous finding that MM patients have increased their survival in the last two decades.

Survival rate of odontogenic descending necrotizing mediastinitis. Our experience in last 5 years.

BACKGROUND: Descending necrotising mediastinitis is one of the most lethal and least frequent forms of mediastinitis. It is a life-threatening infection most frequently originating from an oropharyngeal or odontogenic infection. MATERIAL AND METHODS: A retrospective study of 6 patients diagnosed and treated for descending necrotising mediastinitis between 2015 and 2020 is reported. RESULTS: All patients were male, mean age of 34.83 years; 66% were smokers. 83% had an orocervical infection and 34% had initial mediastinal spread. All patients were treated initially with empirical broad-spectrum antibiotics and surgical drainage, with subsequent admission to the Intensive Care Unit; only one of them required tracheostomy. The mean hospital stay was 27.37 days. After a mean follow-up of 6 months, 100% of the cases had a complete recovery. CONCLUSIONS: Early diagnosis and surgical treatment combined with improved life-support treatment in intensive care units and broad-spectrum antibiotic therapy leads to a decrease in associated mortality.

Navigation in surgical arthroscopy of the temporomandibular joint.

Surgical navigation is a technique that has evolved greatly in recent years. It allows surgeons to navigate through the surgical field in real time, and helps to locate anatomical structures or lesions and to place devices in complex anatomical regions with relatively high accuracy. In this article, we describe the application of surgical navigation in temporomandibular joint (TMJ) arthroscopy using an optical surgical navigator for a more precise diagnosis and to accurately place instruments in the desired position, especially in lateral pterygoid myotomy. We believe this technique will extend our understanding of the TMJ anatomy and will improve functional results in TMJ arthroscopy.

Changes of CD3+CD56+ γδ T cell number and apoptosis during hospital admission are related to mortality in septic patients.

Immunoparalysis and apoptosis of T cells are serious problems for the evolution of septic patients. We aimed to relate changes in the number of αß and γδ T cells during hospital stay to the poor evolution of sepsis. In this prospective study, we recruited a total of 92 septic patients from the Emergency and Intensive Care Departments of two Hospitals, according to the latest criteria for the definition and management of sepsis. According to the severity of the septic process, there was a progressive decrease in T cells, being much more intense in γδ T cells. This decrease recovered in surviving patients, but CD3+CD56+ γδ T cells continued to decreased during hospital stay in non-surviving patients. Apoptosis increased in sepsis. Cell death of CD3+CD56+ γδ T cells progressively increased according to the severity of sepsis, especially in non-surviving patients.

Large cell neuroendocrine carcinoma on the floor of the mouth: a rare entity in an unusual location.

Neuroendocrine carcinomas (NEC) are a group of malignant neoplasms usually located in the lungs or gastrointestinal tract. Fewer cases are located in the head and neck, and in these rare presentations, the lingual tonsil, larynx, and major salivary glands are the most frequently affected sites. NECs exhibit similar characteristics regardless of where they arise. However, because these neoplasms are rare, a clear understanding of their aetiopathogenesis has yet to be described, and options for treatment have varied and are not unified. A rare NEC of the floor of the mouth is reported here; it appears that this location has not been reported previously. The diagnosis was established through histopathological analysis, and the patient underwent systemic treatment. He had a partial response to treatment in the first 3 months, but died 6 months after the initial diagnosis. This highly uncommon tumour can pose a significant diagnostic challenge for clinicians and pathologists alike and can result in diagnostic delay.

Impact of COVID-19 in patients with multiple myeloma based on a global data network.

The COVID-19 pandemic has represented a major cause of morbidity/mortality worldwide, overstressing health systems. Multiple myeloma (MM) patients show an increased risk for infections and they are expected to be particularly vulnerable to SARS-CoV-2 infection. Here we have obtained a comprehensive picture of the impact of COVID-19 in MM patients on a local and a global scale using a federated data research network (TriNetX) that provided access to Electronic Medical Records (EMR) from Health Care Organizations (HCO) all over the world. Through propensity score matched analyses we found that the number of new diagnoses of MM was reduced in 2020 compared to 2019 (RR 0.86, 95%CI 0.76-0.96) and the survival of newly diagnosed MM cases decreased similarly (HR 0.61, 0.38-0.81). MM patients showed higher risk of SARS-CoV-2 infection (RR 2.09, 1.58-2.76) and a higher excess mortality in 2020 (difference in excess mortality 9%, 4.4-13.2) than non-MM patients. By interrogating large EMR datasets from HCO in Europe and globally, we confirmed that MM patients have been more severely impacted by COVID-19 pandemic than non-MM patients. This study highlights the necessity of extending preventive measures worlwide to protect vulnerable patients from SARS-CoV-2 infection by promoting social distancing and an intensive vaccination strategies.

Gammadelta T cells as a predictor of surgical relapse of Crohn's disease.

BACKGROUND: We recently demonstrated a decrease in the overall lymphocyte population in the peripheral blood of patients with CD compared to healthy controls and this decrease is more evident in γδ T lymphocytes. The percentages of T cell subsets could reflect the risk of surgical relapse in CD patients. The aim of this study is to study the correlation between αß and γδ T cell subsets in the peripheral blood of patients with CD and the risk for surgery during follow up. METHODS: A prospective study of 102 patients with CD compared with 102 healthy subjects (control group) matched by age and sex was conducted. Lymphocytic populations of CD3+, CD4+, CD8+, CD56+, and αß and γδ T cell subsets were measured in the peripheral blood of all participants. RESULTS: We found evidence of a relationship between lower γδ T cell levels and risk of surgical relapse in CD. The lowest subsets observed in CD patients with surgical relapse were CD3+γδ, CD3+CD8+γδ and CD3+CD56+γδT cells. We observed a relationship between a decrease in γδ T cells and the most severe forms of the disease. The lowest levels of CD3+γδ and CD3+CD8+γδT cells were observed in the fistulizing phenotype. CONCLUSIONS: The deficit of γδ T cells was related with the severity and the risk for surgical relapse in CD patients. Patients with CD3+γδ deficit were more prone to surgery than patients without this deficit. These results suggest that γδ T cells could be used as markers of poor prognosis of CD following the diagnosis of the disease.

A comparison of the human and mouse protein corona profiles of functionalized SiO2 nanocarriers.

Nanoparticles are a promising cancer therapy for their use as drug carriers given their versatile functionalization with polyethylene glycol and proteins that can be recognized by overexpressed receptors in tumor cells. However, it has been suggested that in biological fluids, proteins cover nanoparticles, which gives the proteins a biological identity that could be responsible for unexpected biological responses: the so-called protein corona. A relevant biological event that is usually ignored in protein-corona formation is the interspecies differences in protein binding, which can be involved in the discrepancies observed in preclinical studies and the nanoparticle safety and efficiency. Hence, the aim of this study was to determine the differences between human and mouse plasma protein corona profiles in an active therapy model using silicon dioxide nanoparticles (SiO2 nanoparticles) functionalized with polyethylene glycol and transferrin. Functionalized SiO2 nanoparticles were made with a primary particle size of 25 nm and a transferrin content of 50 µg mg-1 of nanoparticles and were PEGylated with a cross-linker. The proteomic analysis by nanoliquid chromatography tandem-mass spectrometry (nanoLC-MS/MS) showed interspecies differences. The most abundant proteins found in the human protein corona profile were immunoglobulins, actin cytoplasmic 1, hemoglobin subunit beta, serotransferrin, ficolin-3, complement C3, and apolipoprotein A-1. Meanwhile, the mouse protein corona adsorbed the serine protease inhibitor A3K, serotransferrin, alpha-1-antitrypsin 1-2, hemoglobin subunit beta, and fibrinogen gamma and beta chains. These protein-corona profile differences in the functionalized SiO2 nanoparticles indicate that biological responses observed in in vivo models could not be translated to clinical use and must be considered in the interpretation of preclinical trials in order to design more efficient and safer nanomedicines.

Allergenicity of vertebrate tropomyosins: challenging an immunological dogma

With the exception of tilapia tropomyosin, other anecdotic reports of tropomyosin recognition of vertebrate origin are generally not accompanied by clinical significance and a dogmatic idea is generally accepted about the inexistence of allergenicity of vertebrate tropomyosins, based mainly on sequence similarity evaluations with human tropomyosins. Recently, a specific work-up of a tropomyosin sensitised patient with seafood allergy, demonstrated that the IgE-recognition of tropomyosin from different fish species can be clinically relevant. We hypothesise that some vertebrate tropomyosins could be relevant allergens. The hypothesis is based on the molecular evolution of the proteins and it was tested by in silico methods. Fish, which are primitive vertebrates, could have tropomyosins similar to those of invertebrates. If the hypothesis is confirmed, tropomyosin should be included in different allergy diagnosis tools to improve the medical protocols and management of patients with digestive or cutaneous symptoms after fish intake

Efectos de la actividad física en la calidad de vida relacionada con la salud en adultos con osteopenia y osteoporosis: revisión sistemática y metaanálisis / Effects of physical activity on health-related quality of life in adults with osteopenia and osteoporosis: systematic review and metaanalisis

Objetivo: Identificar el efecto de la actividad física en la calidad de vida relacionada con la salud en adultos con osteopenia y osteoporosis. Estrategia de búsqueda: Se consultaron las bases de datos Pubmed/MEDLINE, EMBASE, LILACS y el Registro Cochrane Central de Ensayos Controlados (CENTRAL), y los buscadores de Scielo, y Science Direct. En estas se identificaron ensayos clínicos aleatorizados. Resultados: Se encontraron seis estudios (n = 371) que después de evaluación tenían bajo riesgo de sesgo y alta calidad metodológica. No se observan diferencias entre los grupos intervenidos con actividad física y los de cuidado usual tanto para la calidad de vida como para indicadores de densitometría ósea, lo que se asume está dado por el hecho de que el cuidado usual incluye la práctica regular de ejercicio sumado a la heterogeneidad clínica de los estudios, que incluye el tipo de participantes y tiempos de intervención, los cuales no permiten demostrar el impacto de la actividad física. Conclusiones: La actividad física representa una estrategia no farmacológica segura, con efectos positivos en adultos con osteopenia y osteoporosis

Determination of Anti-Anisakis Simplex Antibodies and Relationship with αß and γδ Lymphocyte Subpopulations in Patients with Crohn's Disease.

BACKGROUND: The etiology of Crohn's disease (CD) is still unknown although new theories are based on defects in innate immunity. We have previously shown a decrease in γδ T cells in CD patients. Previous studies have shown a high prevalence of anti-A. simplex immunoglobulins in CD patients. The diminution of γδ T cells in the peripheral blood and intestinal mucosa of CD patients may create a state of immunosuppression that would facilitate A. simplex infection. AIMS: To study the antibody responses to Anisakis antigens in Crohn's disease patients and its relationship with αß and γδ T cell subsets. METHODS: We recruited 81 CD patients and 81 healthy controls. αß and γδ T cell subsets and anti-A. simplex antibodies were measured. RESULTS: Levels of anti-A. simplex IgG and IgM were significantly increased in CD patients. Almost 20% of CD patients were positive for IgG and IgM anti-A. simplex versus only 3.7 and 2.5%, respectively, in normal subjects. However, lower specific IgA levels were observed in the group of CD patients versus healthy subjects. We found an association between CD3 + CD8 + Î³Î´ subset and IgM anti-A. simplex levels. In ileal cases and stricturing behavior of CD, we observed the highest levels of specific antibodies with the exception of anti-A. simplex IgA. CONCLUSIONS: The relationship of specific antibodies with a γδ T cell deficiency makes these cell candidates to play a role in the immune response against Anisakis. In addition, anti-Anisakis antibodies could be considered as markers of risk of progression in CD.

Long-Term Follow-Up of Bimaxillary Osteomyelitis Associated with Autosomal Dominant Osteopetrosis: A Case Report.

Osteopetrosis (OP) is a rare metabolic bone disease characterized by a generalized increase in skeletal mass. The disease is characterized by increased susceptibility to develop osteomyelitis of the jaws. We report a case of clinical and radiological progression of bimaxillary osteomyelitis in a patient with autosomal dominant OP. The patient presented non simultaneous osteomyelitis in both upper and lower jaws with time interval of 10 years. The osteomyelitis of maxilla resulted in oroantral fistula formation and required surgical closure with Bichat fat pad flap. The mandibular osteomyelitis resulted in sequestra formation and pathological fracture and required multiple debridement procedures. Both maxillary and mandibular osteomyelitic foci were persistent and healing required more than 2 years. The case confirms the possibility of development of non simultaneous bimaxillary osteomyelitis in patients with OP. The case enhances the need of close follow- up and preventive measures in patients with OP.
