As a result, they may be treated with less appropriate antibiotics, causing more side effects and entailing increased costs for health systems. The aim of this investigation was to assess whether patients in the third and fourth age with previously confirmed allergies to BLs had lost sensitization and could tolerate these antibiotics.Patients and methods: Patients allergic to BLs were divided into group A (aged 60–79 years) and B (aged ≥80 years). Clinical history, skin testing, drug challenge tests (DCT) and evaluation of resensitization were used to classify participants as showing immediate reactions, non-immediate reactions, or tolerance. We compared clinical entities, drugs involved, and final outcome by age group.Results: Of 1362 cases evaluated, 565 underwent an allergological study. The skin was the most common organ involved. Anaphylaxis and side chain reactions were more frequent in group A (p

Background: SARS-CoV-2 pneumonia can cause significant long-term radiological changes, even resembling pulmonary fibrosis. However, the risk factors for these long-term effects are unknown. This study aims to assess radiological abnormalities and their possible risk factors six months after hospital discharge due to COVID-19 pneumonia., Material and Methods: This cross-sectional study in a tertiary hospital included adults admitted for COVID-19 pneumonia from March 2020 to February 2021, who underwent high-resolution computed tomography (HRCT) scans of the chest six months after hospital discharge. The primary outcome was radiological abnormalities on HRCT, while the main explanatory variables were drawn from the patient's medical history along with the disease course, analytical indicators, and the treatment received during admission., Results: The 189 included patients had a mean age of 61.5 years; 70.9% were male, and hypertension was the main comorbidity (45%). About two-thirds (67.2%) presented acute respiratory distress syndrome (ARDS). Most (97.9%) received systemic corticosteroid therapy, and 81% presented pathological findings on HRCT, most commonly ground glass (63.5%), followed by bronchial dilatation (36%) and subpleural bands (25.4%). The multivariable analysis showed that age was the main risk factor, associated with most radiological changes. Other factors were the duration of corticosteroid therapy for ground glass (adjusted odds ratio [aOR] 1.020) as well as a longer stay in the intensive care unit (ICU) (aOR 1.290) and high levels of IL-6 for bronchial dilation (aOR 1.002)., Conclusion: Radiological involvement of the lungs six months after COVID-19 pneumonia is frequent, especially ground glass. Elderly patients with prolonged ICU admission and a significant inflammatory response measured by IL-6 are more likely to present worse radiological evolution and are candidates for radiological follow-up after COVID-19 pneumonia., (© 2024.

This study aimed to assess the prevalence of anemia in children of two Guarani communities in Misiones, Argentina, and to analyze its association with socioenvironmental and parasitic factors. This cross-sectional study took place in two villages, Koen Ju and Kaa Poty, and included Mbya Guarani children aged 6 months to 14 years. A multivariable analysis was performed to evaluate the association of anemia with the presence of intestinal parasites. Altogether, 162 children were included in the study: 53.1% were boys, 32.7% had low weight-for-age, and 22.2% low height-for-age. Nearly half (46.9%, n=76) had anemia, which was mainly mild (92.1%), with a few moderate cases (7.9%). Of the 109 children who underwent testing for intestinal parasites, 89 (81.7%) had at least one, and 53 (59.5%) had more than one. The main parasite was Blastocystis hominis (49.5%), followed by Entamoeba coli (47.7%), hookworms (36.7%), and Ascaris lumbricoides (31.5%). In the multivariable analysis, anemia was associated with intestinal parasitosis (adjusted odds ratio [OR] 4.24, 95% confidence interval [CI] 1.08-16.5; p=0.038) and male sex (adjusted OR 2.66; 95% CI 1.08-6.47; p= 0.01). Overall, we found that both anemia and intestinal parasites are common in the pediatric population of the Guarani ethnic group. Intestinal parasites and male sex were associated with the presence of anemia.

Arboviruses represent a threat to transfusion safety for several reasons: the presence of vectors and the notification of autochthonous cases in our region, the recent increase in the number of cases transmitted through blood and/or blood component transfusion, the high prevalence rates of RNA of the main arboviruses in asymptomatic blood donors, and their ability to survive processing and storage in the different blood components. In an epidemic outbreak caused by an arbovirus in our region, transfusion centres can apply different measures: reactive measures, related to donor selection or arbovirus screening, and proactive measures, such as pathogen inactivation methods. The study of the epidemiology of the main arboviruses and understanding the effectiveness of the different measures that we can adopt are essential to ensure that our blood components remain safe., (Copyright © 2024 Elsevier España, S.L.U.

Objectives: To quantify and analyze mortality in patients who die within 30 days of discharge home from a hospital emergency department (ED)., Material and Methods: All patients older than 14 years of age who were discharged home from the ED of a tertiary care hospital over a 5-year period were included. We collected age, sex, and other demographic variables, as well as the Charlson Comorbidity Index (CCI). The outcome variables of interest were 7-day and 30-day mortality and cause of death. Deaths were classified as expected and directly related to the emergency, expected but not directly related, unexpected and directly related, and unexpected and not directly related. A death was classified as an adverse event if it was directly related to a problem of diagnosis or management in the ED, underestimation of severity, or complications of a procedure., Results: Of 519312 patients attended in the ED, 453 599 were discharged home. Of those discharged, 148 died at home within 7 days (32.63 deaths/100 000 discharges) and 355 died within 30 days (78.48 deaths/100 000 discharges). One hundred thirteen deaths (31.8%) were expected and related to the emergency 24.91/100 000), 169 (47.6%) were expected but unrelated 37.26/100 000), 4 (1.1%) were unexpected and related 1.10/100000), and 69 (19.4%) were unexpected and unrelated 15.21/100000). Deaths were considered adverse events related to ED care in 24.2% of the cases. Underestimation of severity was responsible for the highest proportion (10.7%) of such deaths. The median age of patients who died was 83 years, and the median Charlson comorbidity index (CCI) was 6. The most common cause of death was a malignant tumor (23.0%), followed by congestive heart failure (20.2%) and atherosclerotic cardiovascular disease (13.2%). Unexpected deaths related to ED care were significantly related to a higher proportion of adverse events related to diagnosis (P = .001), management (P = .004), and underestimation of severity (P .001)., Conclusion: Early deaths after discharge home from a hospital ED occured in patients of advanced age with concomitant conditions. The main clinical settings were neoplastic and cardiovascular disease. Seven-day and 30-day mortality rates directly related to the emergency visit were low. Adverse events related to ED care played a role in about a quarter of the deaths after discharge.

Background: Human T-lymphotropic viruses (HTLV)-1 infection is endemic in many countries of Central and South America and Caribbean (CSA&C). Neither screening nor surveillance programs exist for HTLV-1/2 infection among pregnant women in this region. Neither in Western nations with large migrant flows from HTLV-1/2 endemic regions., Methods: Systematic review and meta-analysis of the prevalence of HTLV-1/2 infection among CSA&C pregnant women. We included studies searching EMBASE, PubMed/MEDLINE, Scopus, and Web of Science from inception to February 15, 2023. This systematic review followed Preferred Reporting Items for Systematic Reviews and Meta-Analyses reporting guidelines., Results: We identified a total of 620 studies. Only 41 were finally included in the meta-analysis. Most studies (61.0%) were from Brazil and Peru (14.6%). The total number of participants was 343,707. The pooled prevalence of HTLV-1/2 infection among CSA&C pregnant women was 1.30% (95% CI: 0.96-1.69) using anti-HTLV-1/2 antibody screening tests. There was a high heterogeneity (I 2 = 98.6%). Confirmatory tests gave an HTLV-1 infection rate of 1.02% (95% CI: 0.75-1.33)., Conclusions: The prevalence of HTLV-1/2 infection among CSA&C pregnant women is 1.3%, most cases being HTLV-1. This rate is greater than for other microbial agents regularly checked as part of antenatal screening (such as HIV, hepatitis B, or syphilis). Thus, HTLV-1/2 antenatal testing should be mandatory among CSA&C pregnant women everywhere., Competing Interests: Declarations of competing interest The authors have no competing interest to declare., (Copyright © 2024.

Introduction: The global increase in sexual transmitted infections (STI) makes it necessary to seek public health strategies that facilitate rapid and minimally invasive diagnosis. The objective was to evaluate the concordance between vaginal and endocervical samples for STI diagnosis., Materials and Methods: A retrospective cross-sectional study was carried out on vaginal and endocervical samples from women attended in our reference area with symptoms suggestive of vulvovaginitis or for STI screening during the study period., Results: A total of 130 paired samples were analyzed; fifty-seven and 59 samples were positive for vaginal and endocervical specimens (Kappa index of 0.969 (Standard error = 0.022). The sensitivity of the vaginal samples was 96.5% (IC95%: 87.2-99.4), with a specificity of 100% (IC95%: 93.0-100)., Discussion: The introduction of STI screening in vaginal samples in our environment can facilitate rapid and effective diagnosis and allow early treatment of STI. Additionally, it facilitates sample collection and diagnosis in the community setting, essential for optimal screening., (Copyright © 2024 Elsevier España, S.L.U. and Sociedad Española de Medicina Interna (SEMI).

This study aims to describe the epidemiological and clinical characteristics and trends of these admissions in Spain. This retrospective study drew data from the Hospital Discharge Records Database of the Spanish National Health System. We used the diagnostic codes for leprosy from the International Classification of Diseases, ninth and tenth revisions, to retrieve leprosy admissions from 1997 to 2021. There were 1387 hospitalizations for leprosy The number of annual cases decreased gradually, from 341 cases in 1997-2001 to 232 in 2017-2021 ( p < 0.001). Patients' median age increased, from 65 years in 1997-2001 to 76 years in 2017-2021 ( p < 0.001), as did the prevalence of some comorbidities, such as hypertension (15% in 1997-2001 to 27.6% in 2017-2021; p < 0.001). The mortality rate (6%) and the frequency of leprosy complications remained stable. After Spain (79.1%), the most common country of origin was Paraguay (4.4%). Admissions decreased significantly in Andalusia, from 42% in 1997-2001 to 10.8% in 2017-2021 ( p < 0.001), and in the Canary Islands, from 7.9% in 1997-2001 to 2.6% in 2017-2021 ( p = 0.001), whereas they increased in Madrid, from 5.9% in 1997-2001 to 12.1% in 2017-2021 ( p = 0.005). Overall, leprosy admissions in Spain have declined, even in the regions with the highest prevalence. Patients admitted for leprosy have become older and sicker.

Background: Estimating the global influenza burden in terms of hospitalization and death is important for optimizing prevention policies. Identifying risk factors for mortality allows for the design of strategies tailored to groups at the highest risk. This study aims to (a) describe the clinical characteristics of hospitalizations with a diagnosis of influenza over five flu seasons (2016-2017 to 2020-2021), (b) assess the associated morbidity (hospitalization rates and ICU admissions rate), mortality and cost of influenza hospitalizations in different age groups and (c) analyze the risk factors for mortality., Methods: This retrospective study included all hospital admissions with a diagnosis of influenza in Spain for five influenza seasons. Data were extracted from the Spanish National Surveillance System for Hospital Data from 1 July 2016 to 30 June 2021. We identified cases coded as having influenza as a primary or secondary diagnosis (International Classification of Diseases, 10th revision, J09-J11). The hospitalization rate was calculated relative to the general population. Independent predictors of mortality were identified using multivariable logistic regression., Results: Over the five seasons, there were 127,160 hospitalizations with a diagnosis of influenza. The mean influenza hospitalization rate varied from 5/100,000 in 2020-2021 (COVID-19 pandemic) to 92.9/100,000 in 2017-2018. The proportion of influenza hospitalizations with ICU admission was 7.4% and was highest in people aged 40-59 years (13.9%). The case fatality rate was 5.8% overall and 9.4% in those aged 80 years or older. Median length of stay was 5 days (and 6 days in the oldest age group). In the multivariable analysis, independent risk factors for mortality were male sex (odds ratio [OR] 1.14, 95% confidence interval [95% CI] 1.08-1.20), age (<5 years: OR 1; 5-19 years: OR 2.02, 95%CI 1.17-3.49; 20-39 years: OR 4.11, 95% CI 2.67-6.32; 40-59 years: OR 8.15, 95% CI 5.60-11.87; 60-79 years: OR 15.10, 95% CI 10.44-21.84; ≥80 years: OR 33.41, 95% CI 23.10-48.34), neurological disorder (OR 1.97, 95% CI 1.83-2.11), heart failure (OR 1.85, 95% CI 1.74-1.96), chronic kidney disease (OR 1.33, 95% CI 1.25-1.41), chronic liver disease (OR 2.95, 95% CI 2.68-3.27), cancer (OR 1.85, 95% CI 1.48-2.24), coinfection with SARS-CoV2 (OR 3.17, 95% CI 2.34-4.28), influenza pneumonia (OR 1.76, 95% CI 1.66-1.86) and admission to intensive care (OR 7.81, 95% CI 7.31-8.36)., Conclusion: Influenza entails a major public health burden. People aged over 60-and especially those over 80-show the longest hospital stays. Age is also the most significant risk factor for mortality, along with certain associated comorbidities., Competing Interests: The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest., (Copyright © 2024 Ramos-Rincón, Pinargote-Celorio, González-de-la-Aleja, Sánchez-Payá, Reus, Rodríguez-Díaz and Merino.)

Objectives: To study differences in the emergency department treatment of acute poisoning according to biological sex of patients and to assess adherence to care quality indicators., Material and Methods: Retrospective observational study including all cases of acute poisoning diagnosed in patients over the age of 14 years treated in a tertiary care hospital emergency department over a period of 4 years. We analyzed demographic variables, substance type and reason for acute poisoning, degree of adherence to quality indicators, and discharge destination., Results: A total of 1144 cases were included; 710 patients (62.1%) were female and 434 (37.9%) were male. The proportion of deliberate self-poisoning was higher in females (52.3% vs 41.4% in males; P .001); unintentional poisoning was less frequent in females (in 24.9% vs in 30.3% of males; P = .047). Benzodiazepine poisoning was more frequent in females (in 49.6% vs 41.2%; P = .007). Street drug and alcohol poisoning was less common in females. Adherence to quality indicators was high (> 85%) for both sexes., Conclusion: The epidemiologic profile of poisoning is different in females and males. General emergency department adherence to quality indicators can be considered optimal. We detected no qualitative sex-related differences in the care of patients with acute poisoning.

Objectives: At the end of 2022, the football world championship will be held in Qatar. These types of meetings require a risk analysis. It proposes an approach to determine which health risks should be prioritized., Method: We use a mixed methodology (Hierarchical Process Analysis, World Health Organization STAR and European Commission INFORM) to determine the risk level of a total of 12 health entities., Results: Our analysis identifies 6 health entities with a moderate risk. There are 4 whose valuation is as low risk and 2 as very low., Conclusions: In our work we focus the analysis from a point of view of the route of transmission or presentation of health events, which facilitates a visualization of the preventive measures to be implemented, both organizationally and individually by the attendees., (Copyright © 2023 The Authors.

Background: Dengue represents a major public health problem in the Americas in general, and in Posadas (Misiones, Argentina) in particular. This study aimed to assess the seroprevalence of dengue virus infection, analyze associated factors, and determine the proportion of asymptomatic cases., Methods: This prospective cross-sectional study took place from November 2017 to April 2019 in the High Complexity Laboratory of Misiones, at the School Hospital Dr. Ramón Madariaga in Posadas. A random sample of 301 adults (≥ 15 years) was selected from the electoral registry and stratified by geographical area of residence. Sociodemographic, clinical, and laboratory data were collected by means of a survey and serology. Results were analyzed using multivariable logistic regression., Results: The median age of the sample was 33 years; 66% were women, and 46.5% had completed at least secondary school. Anti-dengue IgG antibodies were present in 40.2% of the sample (95% confidence interval [CI] 34.5-45.9%), including 90% of those who reported dengue and 20.5% who did not (odds ratio [OR] 33.25, 95% CI 15.46-71.51, p < 0.001). In the multivariable analysis, adjusted for age, group, gender, and vaccination against yellow fever, seropositivity was associated with having relatives with dengue (adjusted OR 3.96, 95% CI 2.18-7.23; p < 0.001)., Conclusion: Seroprevalence for dengue in Posadas was higher than estimates based on the notification records, and there was a high proportion of asymptomatic cases. Educational level and having a family member who had suffered from dengue were associated with positive serology., Competing Interests: Declaration of Competing Interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2024 The Authors.

Introduction: The objective of this report is to describe the clinical pathway for early treatment of patients with acute SARS-CoV-2 infection and to evaluate the first results of its implementation., Methods: This is a descriptive and retrospective study of the implementation of a clinical pathway of treatment in outpatients (January 1 to June 30 2022). Clinical pathway: detection and referral systems from Primary Care, Emergency services, hospital specialities and an automated detection system; clinical evaluation and treatment administration in the COVID-19 day-hospital and subsequent clinical follow-up. Explanatory variables: demographics, comorbidity, vaccination status, referral pathways and treatment administration., Outcome Variables: hospitalization and death with 30 days, grade 2-3 toxicity related to treatment., Results: Treatment was administered to 262 patients (53,4% women, median age 60 years). The treatment indication criteria were immunosupression (68,3%), and the combination of age, vaccination status and comorbidity in the rest 47,3% of the patients s received remdesivir, 35,9% nirmatrelvir/ritonavir, 13,4% sotrovimab and 2,4% combined treatment with a median of 4 days after symptom onset. Hospital admission was required for 6,1% of the patients, 3,8% related to progression COVID-19. No patient died. Toxicity grade 2-3 toxicity was reported in 18,7%, 89,8% dysgeusia and metallic tasted related nirmatrelvir/ritonavir. Seven patients discontinued treatment due to toxicity., Conclusion: The creation and implementation of a clinical pathway for non-hospitalized patients with SARS-CoV-2 infection is effective and it allows early accessibility and equity of currently available treatments., (Copyright © 2022 Sociedad Española de Enfermedades Infecciosas y Microbiología Clínica.

Background: In Spain, the risk of imported malaria has increased in recent years due to the rise in international travel and migration. Little is known about the knowledge, information sources, clinical practice, and specific needs of primary care physicians (PCPs) concerning malaria despite the pivotal role played by these professionals in managing the health of tourists. The objective of this study was to assess the knowledge, attitudes, and practices of PCPs in Spain regarding malaria., Methods: This research analyses data from (1) a cross-sectional nationwide survey assessing the knowledge and attitudes of PCPs regarding malaria, and (2) a retrospective review of 373 malaria cases appearing in primary care medical records (PCMRs) in the Madrid area over the past 15 years to determine how cases were documented, managed, or characterized in the primary care setting., Results: The survey findings reveal a modest level of self-perceived familiarity with malaria (221/360, 57.6%), even though 32.8% of the practitioners reported having delivered care for confirmed or suspected cases of the disease, these practitioners had greater knowledge of malaria (80.4%) compared to physicians who reported not having delivered care for malaria (19.6%, p < 0.001). Ten percent of the survey participants did not know the name of the mosquito that transmits malaria, and only 40.7% would promptly request malaria testing for a traveller with symptoms after a trip to an endemic area. Responses provided by younger PCPs varied to a greater extent than those of their more experienced colleagues regarding prevention practices and patient management. A review of PCMRs showed that only 65% of all patients were recorded as such. Among those registered, only 40.3% had a documented malaria episode, and of those, only 16.6% received proper follow-up. Only 23.7% of the patients with a PCMR had a record that specifically indicated travel to an endemic country or travel classified as visiting friends and relatives (VFR)., Conclusions: The findings of this study underscore the critical role of PCPs in the field of travel medicine, particularly given the increase in imported malaria cases. These results highlight the need for targeted training in travel medicine and the need to ensure optimal patient education in care settings., (© 2023. The Author(s).)

Introduction: The profound impact of the Covid-19 pandemic, together with other factors such as globalisation and climate change, has emphasised the growing relevance of Infectious Diseases and Microbiology., Methods: The Spanish scientific production in both categories of the Web of Science databases over the period 2014-2021 has been analysed., Results: 8037 documents have been identified in Infectious Diseases and 12008 documents in Microbiology (6th most productive country worldwide in both cases, with growth rates of 41% and 46.2%, respectively). Both areas present a high degree of international collaboration (45-48% of the documents) and between 45-66% of the documents have been published in journals of excellence (first quartile) according to the rankings of the Journal Citation Reports., Conclusions: Spain is in a prominent position worldwide in both areas, with an outstanding scientific production in journals of high visibility and impact., (Copyright © 2023.

Introduction: The establishment of the Spanish AIDS Research Network (RIS) was a milestone for the promotion of HIV research in Spain. We analyse Spanish HIV research, assessing the role that RIS has played in it., Methods: We identified publications on HIV-AIDS with the participation of Spanish institutions in the Web of Science over the period 2010-2019, characterising research activity by means of bibliometrics and identifying the thematic areas of research through a cluster analysis., Results: A total of 3960 documents have been identified (average of 396 documents/year), 42% of which have been signed in international collaboration. RIS researchers have participated in 60% of the documents, presenting a scientific production and citation significantly higher than authors not linked to the RIS. Five thematic clusters articulate the research, focusing on the clinical and therapeutic approach to people living with HIV, co-infection and co-morbidity with other diseases, the genetic characterisation of the virus, the development of vaccines and the study of its transmission in specific groups or associated with sexual behaviour., Conclusion: Spanish HIV research, largely driven by RIS groups, has reached a stage of maturity, with a notable increase in scientific production, participation in international cooperative networks and an outstanding impact and visibility., (Copyright © 2022 The Author(s).

In 2020, the COVID-19 pandemic followed a two-wave pattern in most countries. Hospital admission for COVID-19 in one wave or another could have affected mortality, especially among the older persons. The objective of this study was to evaluate whether the admission of older patients during the different waves, before SARS-CoV-2 vaccination was available, was associated with a different mortality. We compared the mortality rates of patients hospitalized during 2020 before (first wave) and after (second wave) July 7, 2020, included in the SEMI-COVID-19 Registry, a large, multicenter, retrospective cohort of patients admitted to 126 Spanish hospitals for COVID-19. A multivariate logistic regression analysis was performed to control for changes in either the patient or disease profile. As of December 26, 2022, 22,494 patients had been included (17,784 from the first wave and 4710 from the second one). Overall mortality was 20.4% in the first wave and 17.2% in the second wave (risk difference (RD) - 3.2%; 95% confidence interval (95% CI) - 4.4 to - 2.0). Only patients aged 70 and older (10,973 patients: 8571 in the first wave and 2386 in the second wave) had a significant reduction in mortality (RD - 7.6%; 95% CI - 9.7 to - 5.5) (unadjusted relative risk reduction: 21.6%). After adjusting for age, comorbidities, variables related to the severity of the disease, and treatment received, admission during the second wave remained a protective factor. In Spain, patients aged 70 years and older admitted during the second wave of the COVID-19 pandemic had a significantly lower risk of mortality, except in severely dependent persons in need of corticosteroid treatment. This effect is independent of patient characteristics, disease severity, or treatment received. This suggests a protective effect of a better standard of care, greater clinical expertise, or a lesser degree of healthcare system overload., (© 2023. Springer Nature Limited.)

Introduction: The evidence for remdesivir therapy in immunocompromised patients is scarce. To evaluate remdesivir (RDV) effectiveness and safety in COVID-19 outpatients at high risk for progression in a real-world setting, we compare the outcome in immunocompromised (IC) patients with that in non-immunocompromised patients. Methods: Two hospitals conducted a retrospective study of all adult patients with mild-to-moderate SARS-CoV-2 infection at high risk for disease progression who were treated as outpatients with a 3-day course of RDV (1st January-30th September 2022). The primary effectiveness endpoint was a composite of any cause of hospitalization or death by day 30. A multiple logistic regression model was built to explore the association between immune status and clinical outcome, estimating adjusted odds ratios [aORs (95% CI)]. Results: We have included 211 patients, of which 57% were males, with a median age of 65 years (IQR 53-77), 70.1% were vaccinated (three or four doses), and 61.1% were IC. The median duration of symptoms before RDV treatment was 3 days (IQR 2-5). During follow-up, 14 (6.6%) patients were hospitalized, of which 6 (2.8%) were hospitalized for COVID-19 progression. No patient required mechanical ventilation, and two patients died (non-COVID-19-related). After accounting for potential confounders, only anti-CD20 treatment was associated with the composed outcome [aOR 5.35 (1.02-27.5, 95% CI)], whereas the immunocompetence status was not [aOR 1.94 (0.49-7.81, 95% CI)]. Conclusion: Early COVID-19 outpatient treatment with a 3-day course of remdesivir in vaccinated patients at high risk for disease progression during the Omicron surge had a good safety profile. It was associated with a low rate of all-cause hospitalization or death, regardless of immunocompetence status., Competing Interests: The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest., (Copyright © 2023 Ramos-Rincón, Pinargote-Celorio, Llenas-García, Moreno-Pérez, González-Cuello, Gonzalez-de-la-Aleja, Martínez-López, Reus, García-López, Rodríguez, Boix and Merino.)

Introduction: The long-term effects of SARS-CoV-2 are unclear, as are the factors influencing the evolution. Objective: to assess health-related quality of life 1 year after a hospital admission due to COVID-19 and to identify factors that may influence it., Materials and Methods: Retrospective observational study in a tertiary hospital from March 2021 to February 2022. Inclusion criteria: ≥18 years old and admitted for SARS-CoV-2 infection. Exclusion criteria: death, not located, refusal to participate, cognitive impairment, and language barrier. Variables: demographic data, medical history, clinical and analytical outcomes during hospital admission, treatment received, and vaccination against SARS-CoV-2 following admission. Participants were interviewed by phone 1 year after admission, using the SF-36 quality of life questionnaire., Results: There were 486 included patients. The domains yielding the lowest scores were general health (median 65%, interquartile range [IQR] 45-80), vitality (median 65%, IQR 45-80), and mental health (median 73.5%, IQR 60-100). Multivariable analysis showed that female sex and fibromyalgia/fatigue had a negative influence on all domains. Obesity was associated with worse outcomes in physical functioning, physical role, bodily pain, and vitality. Other factors associated with worse scores were an older age in physical functioning and high age-adjusted Charslon comorbidity in physical functioning and general health. Age was associated with better results in emotional role and High C-reactive protein at admission on vitality., Conclusion: One year after admission for COVID-19, quality of life remains affected, especially the domains of general health, vitality, and mental health. Factors associated with worse outcomes are female sex, fibromyalgia/chronic fatigue, and obesity., Competing Interests: The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest., (Copyright © 2023 Pérez Catalán, Roig Martí, Fabra Juana, Domínguez Bajo, Herrero Rodríguez, Segura Fábrega, Varea Villanueva, Folgado Escudero, Esteve Gimeno, Palomo de la Sota, Cardenal Álvarez, Mateu Campos, Usó Blasco and Ramos Rincón.)

Dengue is globally the most important arboviral infection. It is caused by the dengue virus and it is generally transmitted by Aedes mosquitoes' bites (Ae aegypti or Ae albopictus). In Spain it was initially eradicated in the 20th century, together with the Ae aegypti vector, and currently most of the cases reported in Spain are imported by travelers from countries with dengue transmission (imported dengue). However, in recent years, cases of dengue have been described in people residing in Spain who had not traveled to areas with known transmission (autochthonous dengue), transmitted by Aedes albopictus (the so-called tiger mosquito), present especially in the Mediterranean basin. Therefore, a good knowledge of this potentially severe disease is required, so that it can be diagnosed early, and managed correctly, thus reducing its mortality, as well as its eventual autochthonous transmission., (Copyright © 2023 Elsevier España, S.L.U. and Sociedad Española de Medicina Interna (SEMI).

Biologicals have transformed the management of severe disease phenotypes in psoriasis and are often prescribed in women of childbearing age. However, information on safety of biologicals in pregnancy are lacking. We conducted a systematic review and meta-analysis aimed to describe the characteristics and pregnancy outcomes in women with psoriasis exposed to biologics within 3 months before or during pregnancy, and to estimate the pooled prevalence of spontaneous, elective and total abortions, and congenital malformations in their newborns. Bibliographic searches were performed in the PubMed, Embase, Scopus and Web of Science databases up to 14 April 2022. No restrictions on sample size or publication date were applied. Review performance complied with PRISMA guidelines, and two reviewers assessed randomized controlled trials and nonrandomized studies reporting pregnancy outcomes in women exposed to biologics indicated for psoriasis during the pre-gestational and/or gestational period. Studies focusing on rheumatologic or gastroenterological immune-mediated inflammatory diseases were excluded. Regardless of data heterogeneity, a random-effects model was used to pool prevalence estimates. We included 51 observational studies, involving 739 pregnancies exposed to approved biologics for psoriasis. Administration was mostly (70.4%) limited to the first trimester, and the most common drug was ustekinumab (36.0%). The estimated prevalence of miscarriage was 15.3% (95% confidence interval [CI] 12.7-18.0) and elective abortions, 10.8% (95% CI 7.7-14.3). Congenital malformations occurred in about 3.0% (95% CI 1.6-4.8) of live births exposed to biologics during pregnancy. Altogether, exposure to biologics for psoriasis during pregnancy and/or conception does not seem to be associated with an increased risk of miscarriage/abortion or congenital malformations, showing similar rates to the general population. These results suggest that biologic drugs are safe and pose an acceptable risk to the foetuses/neonates., (© 2023 The Authors.

Background: Emerging evidence suggests that frailty may be a significant predictor of poor outcomes in older individuals hospitalized due to COVID-19. This study aims to determine the prognostic value of frailty on intrahospital patient survival., Methods: This observational, multicenter, nationwide study included patients aged 70 years and older who were hospitalized due to COVID-19 in Spain between March 1 and December 31, 2020. Patient data were obtained from the SEMI-COVID-19 Registry of the Spanish Society of Internal Medicine. Frailty was assessed using the Clinical Frailty Scale. The primary outcome was hospital survival. Cox proportional hazards models were used to assess predictors of survival., Results: A total of 1,878 participants (52% men and 48% women) were included, with 1,351 (71.9%) survivors and 527 (28.1%) non-survivors. The non-survivor group had higher mean age (83.5 vs. 81 years), comorbidities (6.3 vs. 5.3 points on the Charlson index), degree of dependency (26.8% vs. 12.4% severely dependent patients), and frailty (34.5% vs. 14.7% severely frail patients) compared to survivors. However, there were no differences in terms of sex. Our results demonstrate that a moderate-severe degree of frailty is the primary factor independently associated with shorter survival [HR 2.344 (1.437-3.823; p<0.001) for CFS 5-6 and 3.694 (2.155-6.330; p<0.001) for CFS 7-9]., Conclusion: Frailty is the main predictor of adverse outcomes in older patients with COVID-19. The utilization of tools such as the Clinical Frailty Scale is crucial for early detection in this population., (Copyright © 2023 Elsevier España, S.L.U. and Sociedad Española de Medicina Interna (SEMI).

COVID-19 is responsible for high mortality, but robust machine learning-based predictors of mortality are lacking. To generate a model for predicting mortality in patients hospitalized with COVID-19 using Gradient Boosting Decision Trees (GBDT). The Spanish SEMI-COVID-19 registry includes 24,514 pseudo-anonymized cases of patients hospitalized with COVID-19 from 1 February 2020 to 5 December 2021. This registry was used as a GBDT machine learning model, employing the CatBoost and BorutaShap classifier to select the most relevant indicators and generate a mortality prediction model by risk level, ranging from 0 to 1. The model was validated by separating patients according to admission date, using the period 1 February to 31 December 2020 (first and second waves, pre-vaccination period) for training, and 1 January to 30 November 2021 (vaccination period) for the test group. An ensemble of ten models with different random seeds was constructed, separating 80% of the patients for training and 20% from the end of the training period for cross-validation. The area under the receiver operating characteristics curve (AUC) was used as a performance metric. Clinical and laboratory data from 23,983 patients were analyzed. CatBoost mortality prediction models achieved an AUC performance of 84.76 (standard deviation 0.45) for patients in the test group (potentially vaccinated patients not included in model training) using 16 features. The performance of the 16-parameter GBDT model for predicting COVID-19 hospital mortality, although requiring a relatively large number of predictors, shows a high predictive capacity., (© 2023.
