Retrospective study on the outcomes and satisfaction with endometrial ablation by bipolar energy (NovaSure®) for the treatment of heavy menstrual bleeding.

PURPOSE: To determine the effectiveness, safety, and participant satisfaction with endometrial ablation by bipolar energy (NovaSure®) in the treatment of heavy menstrual bleeding (HMB), and to investigate factors associated with poorer outcomes. METHODS: Multicenter retrospective observational study based on medical record review of the outcomes related to endometrial ablation by the bipolar-energy technique procedure to treat HMB in the setting of three university teaching hospitals in Spain. RESULTS: A total of 333 women were included in the study. Most bipolar-energy ablations were successful (85.12%; n = 269 out of 316), with amenorrhea the most frequent outcome (39.6%, n = 131 out of 316). The majority of participants had no complications (95.5%; n = 317 out of 332), and of those who did, only 2.1% were related to the technique. No further treatment was required for HMB in 82.8% of women (n = 274 out of 331), and surgery was avoided in 91.8%; only 5.9% of women underwent ablation-related hysterectomy. In women with previous transverse cesarean sections (CS), 91.0% avoided subsequent surgical treatment. Eighty-six percent of women (n = 221 out of 257) were satisfied with the procedure. CONCLUSION: Bipolar-energy ablation is very effective and safe for the treatment of HMB and yielded a high rate of participant satisfaction in our setting. The presence of comorbidities or previous CS may slightly reduce the effectiveness of the method, while performing concomitant surgery (mainly curettage) increases the rate of complications. Notably, despite the known increased risk of hysterectomy, most participants with previous CSs who underwent ablation avoided major surgery.

Association between exposure to perfluoroalkyl substances (PFAS) and endometriosis in the ENDEA case-control study.

BACKGROUND: Perfluoroalkyl substances (PFAS) are environmental contaminants present in a wide range of consumer products and frequently detected in drinking water. They have been linked to adverse reproductive health outcomes in women, but there is limited human evidence on the association of PFAS exposure with endometriosis. OBJECTIVE/AIM: To explore the association between plasma concentrations of several PFAS, considered individually and as a mixture, and the risk of endometriosis in women of childbearing age. METHODS: Between 2018 and 2020, 42 patients with endometriosis and 90 controls undergoing abdominal surgery were recruited at two public hospitals in Granada, Spain. The presence or absence of endometriosis was ascertained by laparoscopic inspection of the pelvis and biopsy of suspected lesions (histological diagnosis). Concentrations of 10 PFAS were quantified in plasma samples from participants. Unconditional logistic regression was employed to examine associations of individual PFAS and summed concentrations of short (∑SC) and long-chain (∑LC) PFAS with odds of endometriosis, and quantile g-computation was used to assess their mixture effect. RESULTS: In models adjusted for age, schooling, and parity, perfluorotridecanoic acid (PFTrDA) was associated with higher odds of endometriosis (odds ratio [OR] = 1.74; 95 % CI = 1.11-2.73 per 2-fold increase in plasma concentrations), while marginally significant associations were found for perfluorohexane sulfonate (PFHxS) (OR = 1.45, 95 % CI = 0.94-2.21) and ∑SC PFAS (OR = 1.48; 95 % CI = 0.96-2.30). No associations were found for the remaining PFAS. The PFAS mixture was non-significantly associated with 1.7-fold higher odds of endometriosis (95 % CI = 0.73-3.80), with perfluorononanoic acid (PFNA), PFHxS, and PFTrDA being the major contributors to this effect. CONCLUSIONS: These findings suggest that exposure to certain PFAS may increase the odds of endometriosis. However, given the modest sample size, further studies are warranted to verify these results.

Suprapiamadre: Análisis Etimológico y Propuesta Terminológica para la Cuarta Meninge en Terminologia Anatomica, Terminologia Neuroanatomica y Terminologia Histologica / Suprapiamadre: Etymological Analysis and Terminological Proposal for the Fourth Meninge in Terminologia Anatomica, Terminologia Neuroanatomica and Terminologia Histologica

A lo largo de la historia, el conocimiento sobre las meninges ha evolucionado desde los primeros registros en el papiro de Edwin Smith hasta la actualidad, donde se ha descrito SLYM, una cuarta meninge que separa el espacio subaracnoideo en un compartimiento superficial y otro profundo, a la que se le atribuyen funciones de barrera semipermeable y de nicho de células inmunes para la vigilancia y protección del sistema nerviosos central. La FIPAT contiene un grupo de terminologías que son mundialmente aceptadas para la descripción de las estructuras del cuerpo humano, sin embargo, en Terminologia Anatomica, Ter- minologia Neuroanatomica y Terminologia Histologica, aún no se encuentra incluido el término SLYM para representar una cuarta meninge, quizás porque sea un reciente descubrimiento. El objetivo de este estudio fue sugerir un nuevo término que concuerde con los lineamientos de la FIPAT y con las reglas de Terminología Anatómica Regular (RAT) en reemplazo de SLYM, además de proponer su inclusión en Terminologia Anatomica, Terminologia Neuroanatomica y Terminologia Histologica, previa revisión y aprobación por parte del comité respectivo de la FIPAT. Se revisó el acrónimo SLYM y los elementos que lo conforman (membrana subaracnoidea de tipo linfática), desde un enfoque etimológico, este análisis estuvo acompañado de una revisión a las reglas RAT aceptadas por la FIPAT, que fueron consideradas para examinar su cumplimiento por parte del acrónimo SLYM. Se encontró que SLYM, al igual que los términos que lo componen no cumplen totalmente con las reglas RAT. El acrónimo SLYM no proporciona una descripción adecuada de la estructura que representa, lo que contradice las reglas RAT. Se propone el término Suprapiamater como alternativa, para su inclusión en Terminologia Anatomica, Terminologia Neuroanatomica y Terminologia Histologica, basado en elementos latinos que describen su ubicación y función, mejorando la precisión y claridad en la comunicación científica.

SUMMARY: Throughout history, knowledge about the meninges has evolved from the first records in the Edwin Smith papyrus to the present, where SLYM, a fourth meninge that separates the subarachnoid space into a superficial compartment and another, has been described deep, to which semipermeable barrier and immune cell niche functions are attributed for the surveillance and protection of the central nervous system. The FIPAT contains a group of terminologies that are globally accepted for the description of the structures of the human body, however, in Terminologia Anatomica, Terminologia Neuroanatomica and Terminologia Histologica, the term SLYM to represent a fourth meninge is not yet included, perhaps because be a recent discovery. The objective of this study was to suggest a new term that agrees with the FIPAT guidelines and with the Regular Anatomical Terminology (RAT) rules to replace SLYM, in addition to proposing its inclusion in Terminologia Anatomica, Terminologia Neuroanatomica and Terminologia Histologica, previously review and approval by the respective FIPAT committee. The acronym SLYM and the elements that make it up (Subarachnoid Lymphatic-like Membrane) were reviewed from an etymological approach. This analysis was accompanied by a review of the RAT rules accepted by FIPAT, which were considered to examine their compliance by the acronym SLYM. It was found that SLYM, like the terms that compose it, do not fully comply with the RAT rules. The SLYM acronym does not provide an adequate description of the structure it represents, which contradicts the RAT rules. The term suprapiamater is proposed as an alternative, for inclusion in Terminologia Anatomica, Terminologia Neuroanatomica and Terminologia Histologica, based on Latin elements that describe its location and function, improving precision and clarity in scientific communication.

Infective endocarditis in HIV-infected patients. Analysis of a national cohort.

BACKGROUND: There is limited recent evidence about infective endocarditis (IE) in HIV-infected patients. Our aim was to compare IE according to HIV infection presence. METHODS: Consecutive inclusion of IE patients at 46 Spanish hospitals between 2008 and 2021. RESULTS: From 5667 patients, 99 were HIV-infected (1·7%; 50 intravenous drugs users). Compared to patients without HIV, HIV-infected patients were more frequently male (84% vs. 67%), had younger median age (46 vs. 69 years), and less comorbidities, except liver disease (52% vs. 9%) and intravenous drug use (51% vs. 1%). They had more common tricuspid location (36% vs. 5%) and community-acquired IE (82% vs. 63%), vascular (29% vs. 17%) and cutaneous (22% vs. 7%) foci of infection, and Staphylococcus aureus aetiology (46% vs. 22%). Vegetations (84% vs. 72%), vascular phenomena (17% vs. 9%), splenomegaly (30% vs. 11%), and embolisation (41% vs 21%) were also more common. Surgical indication and surgery were less frequent in HIV-infected patients (54% vs 67%, 28% vs 47%, respectively). Median CD4 count in HIV-infected patients was 318 cells/mm3. In-hospital mortality (23% vs. 26%) and one-year mortality (25% vs. 32%) were similar in both groups. HIV infection was not independently associated with in-hospital (odds ratio 1·1, 95% CI 0·6-1·9) nor one-year mortality (hazard ratio 0·8, 95% CI 0·4-1·3). CONCLUSIONS: In the combined antiretroviral therapy era, less than 2% of IE patients have HIV infection. HIV-infected patients have a different clinical profile than those without HIV, but the presence of HIV does not seem to impact on IE prognosis.

Clinical characteristics and outcomes of aortic prosthetic valve endocarditis: comparison between transcatheter and surgical bioprostheses.

PURPOSE: Most data regarding infective endocarditis (IE) after transcatheter aortic valve implantation (TAVI) comes from TAVI registries, rather than IE dedicated cohorts. The objective of our study was to compare the clinical and microbiological profile, imaging features and outcomes of patients with IE after SAVR with a biological prosthetic valve (IE-SAVR) and IE after TAVI (IE-TAVI) from 6 centres with an Endocarditis Team (ET) and broad experience in IE. METHODS: Retrospective analysis of prospectively collected data. From the time of first TAVI implantation in each centre to March 2021, all consecutive patients admitted for IE-SAVR or IE-TAVI were prospectively enrolled. Follow-up was monitored during admission and at 12 months after discharge. RESULTS: 169 patients with IE-SAVR and 41 with IE-TAVI were analysed. Early episodes were more frequent among IE-TAVI. Clinical course during hospitalization was similar in both groups, except for a higher incidence of atrioventricular block in IE-SAVR. The most frequently causative microorganisms were S. epidermidis, Enterococcus spp. and S. aureus in both groups. Periannular complications were more frequent in IE-SAVR. Cardiac surgery was performed in 53.6% of IE-SAVR and 7.3% of IE-TAVI (p=0.001), despite up to 54.8% of IE-TAVI patients had an indication. No differences were observed about death during hospitalization (32.7% vs 35.0%), and at 1-year follow-up (41.8% vs 37.5%), regardless of whether the patient underwent surgery or not. CONCLUSION: Patients with IE-TAVI had a higher incidence of early prosthetic valve IE. Compared to IE-SAVR, IE-TAVI patients underwent cardiac surgery much less frequently, despite having surgical indications. However, in-hospital and 1-year mortality rate was similar between both groups.

Cutibacterium species valvular and cardiac device-related infective endocarditis: contemporary data from the GAMES prospective cohort (2008-2023).

BACKGROUND: Information on infective endocarditis (IE) caused by Cutibacterium spp. is limited and new Duke-ISCVID criteria have not yet been properly assessed. We examined clinical characteristics, outcomes and performance of diagnostic tests for Cutibacterium valvular and cardiac implantable electronic device-related IE (CIED-IE). METHODS: Data corresponding to all episodes of Cutibacterium IE recorded from 2008 to 2023 in a prospective national cohort including 46 Spanish hospitals were examined. Possible IE cases were reassessed using the new criteria. The sensitivity of blood cultures, valvular and CIED cultures, and PCR of the 16SrRNA gene and sequencing (16SPCR) was evaluated. RESULTS: There were 67/6,692 (1%) episodes of IE caused by Cutibacterium spp., 85% affecting men. Of these, 50 were valve-related (45 prosthetic, 5 native) and 17 CIED-related. The new criteria identified 8 additional cases and reclassified 15 as definite IE. Intracardiac complications (abscess, pseudoaneurysm, perforation or intracardiac fistula) occurred in 23/50 (46%) valvular IE episodes, leading to 18% mortality, and up to 40% mortality if surgery was indicated but could not be performed. All CIED-IE cases underwent device removal and no deaths were recorded. Positive diagnosis rates for blood cultures, valve/device cultures and 16SPCR were 52%, 70% and 82%, respectively. CONCLUSION: Cutibacterium IE is a rare yet potentially life-threatening condition that warrants a high index of suspicion in men with endovascular prosthetic material. The new Duke-ISCVID criteria and molecular techniques are useful for its diagnosis. Considering a significant complication rate, cardiac surgery and removal of CIEDs play a key role in reducing mortality.

Malnutrition screening tool and nutritional screening tool for classification of nutritional risk in patients with cancer upon hospital admission: Comparison of diagnostic performance using Global Leadership Initiative on malnutrition criteria as reference.

BACKGROUND & AIMS: Tools for screening of nutrition risk in patients with cancer are usually validated against other screening instruments. Here with the performance of Malnutrition Screening Tool (MST) and Nutritional Screening Tool (NUTRISCORE) to identify the risk of malnutrition was assessed. A full nutritional evaluation and diagnosis following criteria from the Global Leadership Initiative of Malnutrition (GLIM) was the reference standard for the classification of malnutrition. METHODS: Diagnostic test prospective analysis of adult patients with a confirmed diagnosis of cancer. MST, NUTRISCORE and nutritional evaluation and diagnosis by GLIM criteria were independently performed within 24 h of admission to a 4th tier hospital in Bogotá, Colombia. RESULTS: From 439 patients the sensitivity and specificity of MST was 75% and 94% and of NUTRISCORE 45% and 97% respectively. The area under receiver operating characteristic (ROC) curves were 0.90 for MST and 0.85 for NUTRISCORE (p = 0.003). CONCLUSION: The MST showed a significantly better diagnostic performance over NUTRISCORE for detection of malnutrition risk at admission to hospital of patients with cancer.

Trends in epidemiology, surgical management, and prognosis of infective endocarditis during the XXI century in Spain: A population-based nationwide study.

BACKGROUND: Few population-based studies have evaluated the epidemiology of infective endocarditis (IE). Changes in population demographics and guidelines on IE may have affected both the incidence and outcomes of IE. Therefore, the aim of our study is to provide contemporary population-based epidemiological data of IE in Spain. METHODS: Retrospective nationwide observational study using data from the Spanish National Health System Discharge Database. We included all patients hospitalized with IE from January 2000 to December 2019. RESULTS: A total of 64,550 IE episodes were included. The incidence of IE rose from 5.25 cases/100,000 person-year in 2000 to 7.21 in 2019, with a 2% annual percentage change (95% CI 1.3-2.6). IE incidence was higher among those aged 85 or older (43.5 cases/100.000 person-years). Trends across the study period varied with sex and age. Patients with IE were progressively older (63.9 years in 2000-2004 to 70.0 in 2015-2019, p < 0.001) and had more frequent comorbidities and predispositions, including, previous valvular prosthesis (12.1% vs 20.9%, p < 0.001). After adjustment, a progressive reduction in mortality was noted including in 2015-2019 compared to 2010-2014 (adjusted odds ratio 0.93, 95% confident interval 0.88-0.99, p = 0.023)., which was associated with more frequent cardiac surgery in recent years (15.1% in 2010-2014 vs 19.9% in 2015-2019). CONCLUSIONS: In Spain, the incidence of IE has increased during the XXI century, with a more pronounced increase in elderly individuals. Adjusted-mortality decreased over the years, which could be related to a higher percentage of surgery. Our results highlight the changing epidemiology of IE.

Conventional vs. diode laser stapedotomy: audiological outcomes and clinical safety.

PURPOSE: To compare the hearing results and clinical safety of patients undergoing stapes surgery with conventional technique and diode laser. METHODS: Retrospective observational study, which included patients treated with primary stapes surgery performed between January 2009 and January 2020. Three audiometric measurements (PTA, GAP and SDS) were evaluated as main results, evaluated by analysis of covariance (controlling the preoperative value). Intraoperative and postoperative complications were also analyzed. Outcomes were measured 6 months (± 1 month) after surgery. RESULTS: 153 cases were included, 97 operated with conventional technique and 56 with laser technique. Postoperative GAP ≤ 10 dB was obtained in 85.6% of the total sample, 82.5% in the conventional technique and 91.1% in the laser technique. Analysis of covariance showed no significant differences in the three surgery outcomes between the two groups (PTA, p = 0.277; GAP, p = 0.509 and SDS, p = 0.530). Regarding surgical complications, sensorineural damage was higher in the conventional technique group (p = 0.05). On the other hand, there were four cases of facial paresis, all in the laser group, three of them with the 980 nm laser. CONCLUSIONS: Stapedotomy offered a high percentage of hearing success in the two groups studied. There were no significant differences in audiometric result, but there was a differential presentation of complications, being more frequent sensorineural hearing loss in the conventional technique group and facial paresis in the laser group.

Complications of transvaginal radiofrequency ablation of fibroids: A 5-year experience.

Introduction: Transvaginal radiofrequency ablation is a relatively noninvasive approach for the treatment of fibroids in patients who do not wish to undergo conventional surgery. Information on potential complications of this novel technique is very scarce. Methods: Retrospective, descriptive, epidemiological study of 115 patients who underwent transvaginal radiofrequency ablation of fibroids and for whom complications were recorded. Results: We performed 115 transvaginal radiofrequency ablation procedures, we recorded a total of 11 complications (9.6%; 95% CI, 3.8-14.8). Of these, 8 (7.0%) were classified as Clavien-Dindo type I, 1 (0.9%,) as type II, and 2 (1.7%) as type IIIb (severe). No other complications were recorded in a year follow-up. Conclusion: Transvaginal radiofrequency ablation is a treatment option that makes it possible to treat fibroids that are difficult to manage using other techniques. Few associated complications have been described, and most of them are mild.

Clinical presentation, microbiology, and prognostic factors of prosthetic valve endocarditis. Lessons learned from a large prospective registry.

BACKGROUND: Prosthetic valve endocarditis (PVE) is a serious infection associated with high mortality that often requires surgical treatment. METHODS: Study on clinical characteristics and prognosis of a large contemporary prospective cohort of prosthetic valve endocarditis (PVE) that included patients diagnosed between January 2008 and December 2020. Univariate and multivariate analysis of factors associated with in-hospital mortality was performed. RESULTS: The study included 1354 cases of PVE. The median age was 71 years with an interquartile range of 62-77 years and 66.9% of the cases were male. Patients diagnosed during the first year after valve implantation (early onset) were characterized by a higher proportion of cases due to coagulase-negative staphylococci and Candida and more perivalvular complications than patients detected after the first year (late onset). In-hospital mortality of PVE in this series was 32.6%; specifically, it was 35.4% in the period 2008-2013 and 29.9% in 2014-2020 (p = 0.031). Variables associated with in-hospital mortality were: Age-adjusted Charlson comorbidity index (OR: 1.15, 95% CI: 1.08-1.23), intracardiac abscess (OR:1.78, 95% CI:1.30-2.44), acute heart failure related to PVE (OR: 3. 11, 95% CI: 2.31-4.19), acute renal failure (OR: 3.11, 95% CI:1.14-2.09), septic shock (OR: 5.56, 95% CI:3.55-8.71), persistent bacteremia (OR: 1.85, 95% CI: 1.21-2.83) and surgery indicated but not performed (OR: 2.08, 95% CI: 1.49-2.89). In-hospital mortality in patients with surgical indication according to guidelines was 31.3% in operated patients and 51.3% in non-operated patients (p<0.001). In the latter group, there were more cases of advanced age, comorbidity, hospital acquired PVE, PVE due to Staphylococcus aureus, septic shock, and stroke. CONCLUSIONS: Not performing cardiac surgery in patients with PVE and surgical indication, according to guidelines, has a significant negative effect on in-hospital mortality. Strategies to better discriminate patients who can benefit most from surgery would be desirable.

COVID-19 in hospitalized solid organ transplant recipients in a nationwide registry study.

OBJECTIVES: Underlying immunodeficiency has been associated with worse clinical presentation and increased mortality in patients with COVID-19. We evaluated the mortality of solid organ transplant (SOT) recipients (SOTR) hospitalized in Spain due to COVID-19. METHODS: Nationwide, retrospective, observational analysis of all adults hospitalized because of COVID-19 in Spain during 2020. Stratification was made according to SOT status. The National Registry of Hospital Discharges was used, using the International Classification of Diseases, 10th revision coding list. RESULTS: Of the 117,694 adults hospitalized during this period, 491 were SOTR: kidney 390 (79.4%), liver 59 (12%), lung 27 (5.5%), and heart 19 (3.9%). Overall, the mortality of SOTR was 13.8%. After adjustment for baseline characteristics, SOTR was not associated with higher mortality risk (odds ratio [OR] = 0.79, 95% confidence interval [CI] 0.60-1.03). However, lung transplantation was an independent factor related to mortality (OR = 3.26, 95% CI 1.33-7.43), while kidney, liver, and heart transplantation were not. Being a lung transplant recipient was the strongest prognostic factor in SOT patients (OR = 5.12, 95% CI 1.88-13.98). CONCLUSION: This nationwide study supports that the COVID-19 mortality rate in SOTR in Spain during 2020 did not differ from the general population, except for lung transplant recipients, who presented worse outcomes. Efforts should be focused on the optimal management of lung transplant recipients with COVID-19.

Determining the usefulness of systematic 18F-FDG PET/CT for the management of invasive fungal infection (PETIFI project): a prospective national multicentre cohort study protocol.

INTRODUCTION: The evaluation of staging and activity of invasive fungal infection (IFI) is used to adjust the type and duration of antifungal therapy (AT). Typically anatomy-based imaging is used. Positron emission tomography/CT with 18F-fluorodeoxyglucose (18F-FDG PET/CT) not only evaluates more than one body area in one session, but adds functional information to the anatomic data provided by usual imaging techniques and can potentially improve staging of IFI and monitoring of the response to therapy. Our objective is to analyse the impact of the systematic use of 18F-FDG PET/CT in IFI diagnostic and therapeutic management. METHODS AND ANALYSIS: Multicentre prospective cohort study of IFI with performance of systematic 18F-FDG PET/CT at diagnosis and follow-up that will be carried out in 14 Spanish tertiary hospitals. It is planned to include 224 patients with IFI over a 2-year study period. Findings and changes in management before and after 18F-FDG PET/CT will be compared. Additionally, the association of initial quantitative 18F-FDG PET/CT parameters with response to therapy will be evaluated.The primary endpoint is to compare the yield of 18F-FDG PET/CT with standard management without 18F-FDG PET/CT in IFI at initial assessment (staging) and in monitoring the response to treatment.The impact of the results of 18F-FDG PET/CT on the diagnostic-therapeutic management of patients with IFI (added value), as well as the prognostic ability of different quantification parameters of 18F-FDG PET/CT will be secondary endpoints. ETHICS AND DISSEMINATION: The Clinical Research Ethics Committee of Puerta de Hierro-Majadahonda University Hospital approved the protocol of the study at the primary site. We plan to publish the results in high-impact journals. TRIAL REGISTRATION NUMBER: NCT05688592.

El Área del Lenguaje Articulado, Perspectiva Histórica y Denominación Epónima Equívoca: Entre Dax y Broca / Articulated Language Area, Historical Perspective and Erroneous Epomy: Between Dax and Broca

El término epónimo área de Broca corresponde a una región cortical cerebral humana dedicada a la expresión del lenguaje oral y que no siempre se ubica en el giro frontal inferior del lobo frontal en el hemisferio izquierdo. Al estudiar 25 artículos del año 2022 y 25 libros de enseñanza de la neuroanatomía, neurofisiología, neurociencia o áreas asociadas del presente siglo, se estableció y cuantificó la existencia del término área de Broca encontrándose que en los libros había un 96 % de inclusión epónima sobre esta área cortical cerebral y en artículos de revista existía un 100 % del mismo epónimo, además, en ninguno de los libros y artículos se encontró un epónimo diferente. Aunque a lo largo del tiempo, en las ciencias médicas se han usado epónimos para designar estructuras anatómicas como en el caso para tratar de designar el área del cerebro que genera el lenguaje oral, este término no proporciona ninguna información descriptiva ni funcional, lo que equivale a un desatino en la lógica del pensamiento morfológico actual, además que lleva a confusión, pues hace pensar que su descubrimiento inicial fue dado por Broca, equivocando el conocimiento histórico que vincula a Marc Dax como el primero en descubrir esta zona.

SUMMARY: The eponymous Broca's area is a human cerebral cortical region that controls the expression of oral language, and which is not always located in the inferior frontal gyrus of the frontal lobe in the left hemisphere. In a study of 25 articles published in 2022, and 25 teaching books on neuroanatomy, neurophysiology, neuroscience or associated areas, it was found that the term Broca's area was established and quantified. In books there was a 96 % eponymous inclusion of this cerebral cortical area and in journal articles there was 100 % of the same eponym. Furthermore, no other eponyms were found in any of the books and articles. Although over time, eponyms have been used in medical sciences to identify anatomical structures, as in the designation of the area in the brain that controls oral language, this term does not provide any descriptive or functional information. The result is contradictory to current morphological thought and also leads to confusion, erroneously suggesting that the initial discovery was made by Broca, when in fact Marc Dax was the first to discover this area some 30 years earlier.

Use of Monoclonal Antibodies in Immunocompromised Patients Hospitalized with Severe COVID-19: A Retrospective Multicenter Cohort.

OBJECTIVE: We aim to describe the safety and efficacy of sotrovimab in severe cases of COVID-19 in immunocompromised hosts. METHODS: We used a retrospective multicenter cohort including immunocompromised hospitalized patients with severe COVID-19 treated with sotrovimab between October 2021 and December 2021. RESULTS: We included 32 patients. The main immunocompromising conditions were solid organ transplantation (46.9%) and hematological malignancy (37.5%). Seven patients (21.9%) had respiratory progression: 12.5% died and 9.4% required mechanical ventilation. Patients treated within the first 14 days of their symptoms had a lower progression rate: 12.0% vs. 57.1%, p = 0.029. No adverse event was attributed to sotrovimab. CONCLUSIONS: Sotrovimab was safe and may be effective in its use for immunocompromised patients with severe COVID-19. More studies are needed to confirm these preliminary data.

Prevalencia y localización gástrica del Helicobacter pylori en pacientes con atrofia y metaplasia intestinal en una institución de alta complejidad en Colombia / Prevalence and Gastric Location of Helicobacter pylori in Patients with Intestinal Atrophy and Metaplasia in a Tertiary Care Institution in Colombia

Resumen Introducción: Helicobacter pylori juega un papel fundamental en la cascada de carcinogénesis del cáncer gástrico tipo intestinal; sin embargo, no existe claridad respecto a su prevalencia en condiciones preneoplásicas que generan cambio en el microambiente de la mucosa. Actualmente se recomienda la vigilancia endoscópica por protocolo de Sydney cada 2 a 3 años, pero no es clara la presencia de H. pylori en la región subcardial y el fondo gástrico. Objetivo: determinar la prevalencia y localización gástrica del H. pylori en pacientes con condiciones preneoplásicas. Materiales y métodos: estudio de corte transversal en adultos con diagnóstico previo de atrofia o metaplasia intestinal que ingresaron a endoscopia de control, a quienes se les tomaron biopsias del antro, cuerpo, incisura angularis, región subcardial y fondo gástrico. Se realizó un análisis descriptivo de los resultados por regiones gástricas. Resultados: se recolectó la información de 160 pacientes con una prevalencia de H. pylori del 37,5 %, la cual fue en aumento de proximal a distal iniciando con una prevalencia de 12,5 % en la región subcardial hasta una prevalencia de 30,6 % en el antro; hubo un patrón similar en la prevalencia de lesiones preneoplásicas. Se observó una mayor presencia de lesiones avanzadas (displasia, carcinoma) en la incisura. Conclusiones: la prevalencia de H. pylori en condiciones premalignas evidenció una mayor presencia en las regiones distales en comparación con las proximales, y es más frecuente en la región antral y menor en la región subcardial. En cuanto a la distribución gástrica de atrofia y metaplasia, se encontró mayor compromiso en el antro y la incisura, y es baja en la región subcardial y el fondo.

Abstract Introduction: Helicobacter pylori infection plays a critical role in the carcinogenesis cascade of intestinal gastric cancer. However, its prevalence in preneoplastic conditions generating changes in the gastric mucosa is unclear. Currently, endoscopic surveillance using the Sydney protocol is suggested every 2 to 3 years, but the presence of H. pylori infection in the subcardial region and gastric fundus is ill-defined. Objective: to determine the prevalence and gastric location of H. pylori infection in patients with preneoplastic conditions. Materials and methods: a cross-sectional study in adults with a previous diagnosis of atrophy or intestinal metaplasia who entered control endoscopy and were antrum, body, incisura angularis, subcardial region, and gastric fundus biopsied. A descriptive analysis of the results by gastric regions was performed. Results: data from 160 patients with a prevalence of H. pylori of 37.5% were collected. It increased from proximal to distal, starting with a 12.5% prevalence in the subcardial region to a 30.6% prevalence in the antrum. In addition, there was a similar pattern in the prevalence of preneoplastic lesions. Furthermore, advanced lesions (dysplasia, carcinoma) were observed in the incisura. Conclusions: the prevalence of H. pylori in precancerous conditions showed a high presence in the distal regions compared to the proximal ones, and it is more frequent in the antrum and lower in the subcardial region. As for the gastric distribution of atrophy and metaplasia, more involvement was found in the antrum and angular notch and lower in the subcardial region and fundus.

Historia y reconceptualización del término sacro / History and reconceptualization of the sacrum term

RESUMEN: En Terminologia Anatomica el término sacro es identificado con el número 1071. En el humano, es el hueso vertebral de mayor tamaño formado por la fusión de cinco vértebras. El origen del término sacro sigue en discusión y no está del todo claro, además, la pertinencia de esta denominación ha sido poco abordada en la literatura. Así, el objetivo de este artículo fue analizar el término sacro y luego proponer un término para la denominación de esta estructura anatómica siguiendo las recomendaciones de la Federative International Programme for Anatomical Terminology (FIPAT). A este hueso se le llamó sacro, por considerarse sagrado, ya que tiene un profundo significado religioso, aunque también se le ha atribuido otras tradiciones como las místicas y los rituales. El término sacro no favorece el entendimiento, ya que no es descriptivo ni informativo, por lo que sugerimos su cambio a vértebra magna (vertebrae magna), ya que esta propuesta sigue las recomendaciones de la FIPAT, es decir, no solo ser unívoco, sino también preciso.

SUMMARY: In International Anatomical Terminology, the term sacrum is identified with the number 1071. In humans, it is the largest vertebral bone formed by the fusion of five vertebrae. The origin of the term sacrum is still under discussion and is not entirely clear, in addition, the relevance of this denomination has been little addressed in the literature. Thus, the objective of this work was to analyze the term sacrum and then propose a term for the denomination of this anatomical structure following the recommendations of the Federative International Program for Anatomical Terminology (FIPAT). This bone was called sacrum, because it is considered sacred, since it has a deep religious meaning, although other traditions such as mysticism and rituals have also been attributed to it. The term sacrum does not favor understanding, since it is neither descriptive nor informative, so we suggest changing it to vertebrae magna (vertebrae magna), since this proposal follows the FIPAT recommendations, that is, not only be unequivocal, but also accurate.
