RESUMEN
Mental disorders account for a large and increasing health burden worldwide. Characterizing the spectrum of mental disorders and trends over time in adolescents should influence education policies and support preventative strategies at schools. Retrospective study of all hospitalizations in Spain in adolescents 11-18-years old, including mental disorders as diagnosis using the Spanish National Registry of Hospital Discharges. Information was retrieved from 2000 to 2021. During the 22-year study period there were 2,015,589 hospitalizations in adolescents in Spain, of which 118,609 (5.9%) had mental disorders. The rate of psychiatric diagnoses significantly increased from 3.9% in 2000 to 9.5% in 2021. Females accounted for 55.1% of admissions. Mean age at admission declined from 17 to 15 years-old from 2000 to 2021. Mean hospital stay was 10.6 days. Mean in-hospital mortality was 0.24%. By rate order, diagnoses were: substance use disorders (SUD) (40%) > eating disorders (15%) > anxiety/posttraumatic stress disorder (PTSD) (13%) > attention deficit hyperactivity disorder (ADHD) (9%) > major depression (8%) > schizophrenia/psychosis (6%) > autism spectrum disorder (ASD) (6%) > sleep disorder (3%) > suicidal behavior (2%) > sexual disorders (1%). A significant gender dichotomy was noticed, with female predominance for internalizing disorders (i.e., anxiety, depression, suicidal behavior and eating disorders) whereas externalizing disorders (i.e., SUD, ADHD, ASD, schizophrenia and other psychoses) predominated in males. Suicidal behavior and male sex were independent predictors of in-hospital death in multivariate analysis. After the first year of the COVID-19 pandemic, hospitalizations due to mental disorders in adolescents increased by 51% in 2021. There is a growing crisis of mental health among adolescents in Spain. Although the COVID-19 pandemic has unveiled the high rate and severity of psychiatric disorders among youth, a steadily increase has occurred since the beginning of the millennium. Primary preventative strategies should be adapted to distinct and more prevalent mental disorders in adolescents.
RESUMEN
BACKGROUND: A protective hepatitis B virus (HBV) vaccine has been available for four decades. Universal HBV vaccination of infants is recommended by the WHO since the 1990s. Furthermore, HBV immunization is advised for all adults with high-risk behaviours and no seroprotection. However, HBV vaccine coverage remains globally suboptimal. The advent of new more efficacious trivalent HBV vaccines has renewed the interest in HBV vaccination. At present, the extent of current HBV susceptibility in adults remains unknown in Spain. METHODS: HBV serological markers were assessed on a large and representative sample of adults in Spain, including blood donors and individuals belonging to high-risk groups. Serum HBsAg, anti-HBc and anti-HBs were tested in specimens collected during the last couple of years. RESULTS: From 13 859 consecutive adults tested at seven cities across the Spanish geography, overall 166 (1.2%) had positive HBsAg. Past HBV infection was recognized in 14% and prior vaccine immunization in 24%. Unexpectedly, 37% of blood donors and 63% of persons belonging to high-risk groups had no serum HBV markers and therefore were potentially HBV susceptible. CONCLUSION: Roughly 60% of adults living in Spain seem to be HBV susceptible. Waning immunity might be more common than expected. Hence, HBV serological testing should be performed at least once in all adults regardless of risk exposures. HBV vaccine full courses or boosters should be administered to all adults lacking serological evidence of HBV protection.

We have designed, assembled, and evaluated a compact instrument capable of capturing the wavefront phase in real time, across various scenarios. Our approach simplifies the optical setup and configuration, which reduces the conventional capture and computation time when compared to other methods that use two defocused images. We evaluated the feasibility of using an electrically tunable lens in our camera by addressing its issues and optimizing its performance. Additionally, we conducted a comparison study between our approach and a Shack-Hartmann sensor. The camera was tested on multiple targets, such as deformable mirrors, lenses with aberrations, and a liquid lens in movement. Working at the highest resolution of the CMOS sensor with a small effective pixel size enables us to achieve the maximum level of detail in lateral resolution, leading to increased sensitivity to high-spatial-frequency signals.
RESUMEN
In this work, two methods are proposed for solving the problem of one-dimensional barcode segmentation in images, with an emphasis on augmented reality (AR) applications. These methods take the partial discrete Radon transform as a building block. The first proposed method uses overlapping tiles for obtaining good angle precision while maintaining good spatial precision. The second one uses an encoder-decoder structure inspired by state-of-the-art convolutional neural networks for segmentation while maintaining a classical processing framework, thus not requiring training. It is shown that the second method's processing time is lower than the video acquisition time with a 1024 × 1024 input on a CPU, which had not been previously achieved. The accuracy it obtained on datasets widely used by the scientific community was almost on par with that obtained using the most-recent state-of-the-art methods using deep learning. Beyond the challenges of those datasets, the method proposed is particularly well suited to image sequences taken with short exposure and exhibiting motion blur and lens blur, which are expected in a real-world AR scenario. Two implementations of the proposed methods are made available to the scientific community: one for easy prototyping and one optimised for parallel implementation, which can be run on desktop and mobile phone CPUs.

OBJECTIVE: To investigate the impact of COVID19 pandemic on the incidence of health-care associated Clostridioides difficile infection (HA-CDI). METHODS: Retrospective study conducted in the Hospital Universitario de Valme (HUV) and the Hospital General Universitario de Alicante (HGUA) in Spain between January 2019 and February 2021. The study period was divided into non-COVID19 period (2019 and months from 2020 to 2021 with ≤30 hospitalized COVID19 patients) and COVID19 period (months from 2020 to 2021 with >30 COVID19 patients). HA-CDI incidence rates (IR) were calculated as the number of new CDI cases per 10.000 occupied bed-days (OBD) and antimicrobial consumption by means of the defined daily dose (DDD) per 1000 OBD. RESULTS: During the COVID19 period, HA-CDI IR in the HUV was 2.6 per 10.000 OBD, which was lower than what was observed during the non-COVID19 period (4.1 per 10.000 OBD; p = 0.1). In the HGUA, HA-CDI IR during COVID19 period was 3.9 per 10.000 OBD, which was not significantly different to the IR observed during the non-COVID19 period (3.7 per 10.000 OBD; p = 0.8). There was a slight increase in the total antibiotic consumption during COVID19 period in both hospitals, with significant increases of certain high-risk antibiotics as cephalosporins. CONCLSUSIONS: HA-CDI incidence has not increased during the COVID19 pandemic in two tertiary centers in Spain, in spite of a slightly higher antibiotic consumption during the COVID19 period in both hospitals. These findings suggest that, in the presence of strict infection control measures, hospital antibiotic consumption might have a lower impact than expected on HA-CDI.

OBJECTIVE: There is early evidence about Valproic acid (VPA) antiviral effect. Our aim was to investigate the incidence and severity of SARS-CoV-2 infection in VPA users as compared with the general population. MATERIAL AND METHODS: A case-control study nested within a cohort, carried out between March 1 and December 17, 2020. Retrospectively, we identified confirmed SARS-CoV-2 infection patients exposed to VPA in our health department (defined as case). We ascertained VPA regimen (all the time (AT)(292 days) or at least 20% of the study period (notAT)(≥58 days) and if VPA levels were in therapeutic range (ATR) (50-100 mcg/mL) in the last 24 months. We calculated the cumulative incidence of SARS-CoV-2 infection and hospital admission in the cases, comparing it with the general unexposed VPA population (controls). RESULTS: During the study period, 6183 PCR+ were detected among 281035 inhabitants, of these, 746 were hospitalized. 691 patients were on VPA notAT and 628 (90.1%) AT. The indication for VPA use was epilepsy in 54.9%. The incidence of PCR+ was 1.736 % (OR 0.785 (95%CI 0.443-1.390) and 1.910 % (OR 0.865 (95%CI 0.488-1.533), on VPA notAT and VPA AT patients, respectively vs. 2.201% in people without VPA regimen. Those patients with VPA ATR had a lower risk of PCR + (OR 0.233 (95%CI 0.057-0.951) notAT; OR 0.218 (95%CI 0.053-0.890) AT). Hospital admission incidence was lower in patient on VPA (OR was 0.543 (95% CI 0.076 to 3.871). CONCLUSION: Patients with VPA within the therapeutic range had a reduction of SARS-Cov-2 infection incidence greater than 75%. There is a downward trend in the risk of COVID-19 admission by SARS-CoV-2 in patients on VPA therapy. These ï¬ndings warrant further investigation.
RESUMEN
The medium-term serologic response of SARS-CoV-2 infection recovered individuals is not well known. The aims were to quantify the incidence of seropositive failure in the medium term in a cohort of patients with different COVID-19 severity and to analyze its associated factors. Patients who had recovered from mild and severe forms of SARS-CoV-2 infection in an Academic Spanish hospital (March 12-May 2, 2020), were tested for total anti-SARS-CoV-2 antibodies by electrochemiluminescence immunoassay (Elecsys Anti-SARS-CoV-2 test; Roche Diagnostics GmbH). The non-seropositive status (seropositive failure) incidence (95% CI) was determined. Associations were tested by multiple logistic regression in a global cohort and severe pneumonia subpopulation. Of 435 patients with PCR-confirmed SARS-CoV-2, a serological test was carried out in 325: 210 (64.6%) had severe pneumonia (hospitalized patients), 51 (15.7%) non-severe pneumonia (managed as outpatients), and 64 (19.7%) mild cases without pneumonia. After a median (IQR) of 76 days (70-83) from symptom onset, antibody responses may not consistently develop or reach levels sufficient to be detectable by antibody tests (non-seropositive incidence) in 6.9% (95% CI, 4.4-10.6) and 20.3% (95% CI, 12.2-31.7) of patients with and without pneumonia, respectively. Baseline independent predictors of seropositive failure were higher leukocytes and fewer days of symptoms before admission, while low glomerular filtrate and fever seem associated with serologic response. Age, comorbidity or immunosuppressive therapies (corticosteroids, tocilizumab) did not influence antibody response. In the medium-term, SARS-CoV-2 seropositive failure is not infrequent in COVID-19 recovered patients. Age, comorbidity or immunosuppressive therapies did not influence antibody response.

BACKGROUND: European travellers to endemic countries are at risk of malaria and may be affected by a different range of co-morbidities than natives of endemic regions. The safety profile, especially cardiac issues, of artenimol (previously dihydroartemisinin)-piperaquine (APQ) Eurartesim® during treatment of uncomplicated imported falciparum malaria is not adequately described due to the lack of longitudinal studies in this population. The present study was conducted to partially fill this gap. METHODS: Participants were recruited through Health Care Provider's safety registry in 15 centres across 6 European countries in the period 2013-2016. Adverse events (AE) were collected, with a special focus on cardiovascular safety by including electrocardiogram QT intervals evaluated after correction with either Bazett's (QTcB) or Fridericia's (QTcF) methods, at baseline and after treatment. QTcB and/or QTcF prolongation were defined by a value > 450 ms for males and children and > 470 ms for females. RESULTS: Among 294 participants, 30.3% were women, 13.7% of Caucasian origin, 13.5% were current smoker, 13.6% current alcohol consumer and 42.2% declared at least one illness history. The mean (SD) age and body mass index were 39.8 years old (13.2) and 25.9 kg/m2 (4.7). Among them, 75 reported a total of 129 AE (27 serious), 46 being suspected to be related to APQ (11 serious) and mostly labelled as due to haematological, gastrointestinal, or infection. Women and Non-African participants had significantly (p < 0.05) more AEs. Among AEs, 21 were due to cardiotoxicity (7.1%), mostly QT prolongation, while 6 were due to neurotoxicity (2.0%), mostly dizziness. Using QTcF correction, QT prolongation was observed in 17/143 participants (11.9%), only 2 of them reporting QTcF > 500 ms (milliseconds) but no clinical symptoms. Using QTcB correction increases of > 60 ms were present in 9 participants (6.3%). A trend towards increased prolongation was observed in those over 65 years of age but only a few subjects were in this group. No new safety signal was reported. The overall efficacy rate was 255/257 (99.2%). CONCLUSIONS: APQ appears as an effective and well-tolerated drug for treatment of malaria in patients recruited in European countries. AEs and QT prolongation were in the range of those obtained in larger cohorts from endemic countries. Trial registration This study has been registered in EU Post-Authorization Studies Register as EUPAS6942.

BACKGROUND: Tuberculosis (TB) and malnutrition are important causes of morbidity and mortality in children in the developing world. AIMS: To assess the prevalence of pulmonary TB in severely malnourished children and evaluate TB detection using the urine lipoarabinomannan antigen assay (TB-LAM). METHODS: A retrospective analysis was conducted in all pediatric inpatients with severe acute malnutrition at a rural health center in Mozambique, from February to August 2018. All children underwent a physical examination and chest X-ray, and their nasopharyngeal aspirates and stool specimens were studied for mycobacterial culture and subjected to the Xpert MTB/RIF assay. TB-LAM tests were performed on urine. RESULTS: Of 45 included cases, 17 (37.8%) were clinically diagnosed as pulmonary TB. None of these were detected by the Xpert MTB test; 4 (8.9%) nasopharyngeal aspirates were TB-culture positive. Seventeen patients (37.8%)-all clinically diagnosed with TB-tested positive on the TB-LAM, while 23 (51.1%) were negative. In 5 (11.1%), the urine LAM was not done. CONCLUSION: Although our sample size was small, TB was diagnosed and treated in more than a third of included children. The urine TB-LAM test showed a perfect correlation with clinical diagnosis of childhood TB. LAY SUMMARY: Severe acute malnutrition makes children more vulnerable to tuberculosis (TB) infections, but it is difficult to detect TB in children because they cannot always cough up phlegm, which is used in diagnostic processes. This study aimed to find out how many severely malnourished children had TB in Gaza, Mozambique, and to test the accuracy of a less-used diagnostic test: the lipoarabinomannan assay (TB-LAM). Of the 45 severely malnourished children who were admitted to our hospital, 17 were diagnosed with TB by their doctor. The TB-LAM corroborated the clinical diagnosis in all cases, while the other tests (Xpert MTB/RIF assay) and cultures failed to detect most of them. Overall, more than a third of severely malnourished children had TB, and the TB-LAM test-a simple, point-of-care method-was a highly accurate way to diagnose them. While larger studies are needed to confirm these results, our findings suggest that the TB-LAM could vastly improve TB diagnosis in malnourished children.

BACKGROUND: HTLV-1 infection is a neglected disease, despite infecting 10-15 million people worldwide and severe illnesses develop in 10% of carriers lifelong. Acknowledging a greater risk for developing HTLV-1 associated illnesses due to immunosuppression, screening is being widely considered in the transplantation setting. Herein, we report the experience with universal HTLV testing of donors and recipients of solid organ transplants in a survey conducted in Spain. METHODS: All hospitals belonging to the Spanish HTLV network were invited to participate in the study. Briefly, HTLV antibody screening was performed retrospectively in all specimens collected from solid organ donors and recipients attended since the year 2008. RESULTS: A total of 5751 individuals were tested for HTLV antibodies at 8 sites. Donors represented 2312 (42.2%), of whom 17 (0.3%) were living kidney donors. The remaining 3439 (59.8%) were recipients. Spaniards represented nearly 80%. Overall, 9 individuals (0.16%) were initially reactive for HTLV antibodies. Six were donors and 3 were recipients. Using confirmatory tests, HTLV-1 could be confirmed in only two donors, one Spaniard and another from Colombia. Both kidneys of the Spaniard were inadvertently transplanted. Subacute myelopathy developed within 1 year in one recipient. The second recipient seroconverted for HTLV-1 but the kidney had to be removed soon due to rejection. Immunosuppression was stopped and 3 years later the patient remains in dialysis but otherwise asymptomatic. CONCLUSION: The rate of HTLV-1 is low but not negligible in donors/recipients of solid organ transplants in Spain. Universal HTLV screening should be recommended in all donor and recipients of solid organ transplantation in Spain. Evidence is overwhelming for very high virus transmission and increased risk along with the rapid development of subacute myelopathy.

Most of the methods used today for the alignment of segmented mirrors are based on Shack-Hartman wavefront sensors. Other proposed methods are based on curvature sensors. These can be used to cross-check the measurements given by the primary method. We investigate a different approach which employs convolutional neural networks. This technique allows the piston step values between segments to be measured with high accuracy, as well as a large capture range at visible wavelengths. The technique does not require special hardware, and is fast to be used at any time during the observation.
RESUMEN
INTRODUCTION: The bibliometric analysis of production and impact of documents by knowledge area is a quantitative and qualitative indicator of research activity in this field. The aim of this article is to determine the contribution of Spanish research institutions in Infectious Diseases and Microbiology in recent years. MATERIAL AND METHODS: Documents published in the journals included in the categories "Infectious Diseases" and "Microbiology" of the Web of Science (Science Citation Index Expanded) of the ISI Web of Knowledge from the year 2000-2013 were analysed. RESULTS: In Infectious Diseases, Spain ranked fourth worldwide, and contributed 5.7% of the 233,771 documents published in this specialty. In Microbiology, Spain was in sixth place with a production rate of 5.8% of the 149,269 documents of this category. The Spanish production increased over the study period, both in Infectious Diseases and Microbiology, from 325 and 619 documents in 2000 to 756 and 1245 documents in 2013, with a growth rate of 131% and 45.8%, respectively. The journal with the largest number of documents published was Enfermedades Infecciosas y Microbiología Clínica, with 8.6% and 8.2% of papers published in the categories of Infectious Diseases and Microbiology, respectively, and was the result of international collaborations, especially with institutions in the United States. The "index h" was 116 and 139 in Infectious Diseases and Microbiology, placing Spain in fifth place in both categories within countries of the European Union. CONCLUSIONS: In recent years, Spanish research in Infectious Diseases and Microbiology has reached a good level of production and international visibility, reaching a global leadership position.

Malaria is a common parasitic disease diagnosed in the returned traveler. Mortality in travelers with imported malaria is around 2-3%, and one of the main factors associated with poor prognosis is the delay in the diagnosis and treatment. Imported malaria cases usually present with fever, headache and myalgia, but other symptoms may appear. The diagnosis should be performed as soon as possible, using thick smear or rapid diagnostic tests, and a blood smear. Treatment should be initiated urgently. In cases of severe malaria, the use of intravenous artemisinins has proved to be superior to intravenous quinine. This document reviews the recommendations of the expert group of the Spanish Society of Tropical Medicine and International Health (SEMTSI) for the diagnosis and treatment of imported malaria in Spain.

BACKGROUND: Suicide ranks as a leading cause of premature death among adolescents globally. Understanding the trends and key determinants of suicidal behavior in youth are critical for implementing educational policies and supporting preventive strategies in schools. METHODS: This retrospective study examined all hospitalizations due to suicidal behavior in children and adolescents aged 11 to 18 years in Spain, using data from the Spanish National Registry of Hospital Discharges spanning 2000 to 2021. RESULTS: Over the 22-year study period, there were 2,015,589 hospitalizations among adolescents in Spain, with 118,609 (5.9 %) cases involving mental disorders. There were 2855 admissions with suicidal behavior, constituting 2.4 % of the hospitalizations among youth with mental disorders. Girls represented 73.4 % of all hospitalizations, with a median age of 16 years. Admissions for suicidal behavior saw a four-fold increase during the last decade (p < 0.001). The in-hospital mortality rate for adolescents with suicidal behavior doubled that of those hospitalized for other mental disorders. During the first year of the COVID-19 pandemic, admissions of adolescents with suicidal behavior decreased, only to surge by 2.5-fold during 2021. CONCLUSION: Hospital admissions for suicidal behavior among adolescents have risen in Spain over the last two decades. Girls represented 73.4 % of these admissions, yet in-hospital mortality was more frequent in boys.

BACKGROUND: Our aim is analyze the epidemiological factors of enteric fever in Madrid (Spain) over the last 30 years. MATERIAL AND METHODS: A retrospective review was conducted on cases of typhoid and paratyphoid fever studied in the Fundación Jiménez Díaz (Madrid) between 1980 and 2010. Two similar periods in time were studied (P1: 1980-1993; P2: 1994-2010). RESULTS: There was a total of 61 confirmed cases of enteric fever: 51 (84%) were typhoid and 10 were paratyphoid: 45 patients were native Spanish (40 belonging to P1) and 16 were immigrants (15 in P2, with 11 of them coming from the Indian sub-continent). CONCLUSION: Enteric fever must be present in the differential diagnosis of persistent fever without clear focus in immigrants, mainly from the Indian subcontinent, and travelers from endemic areas.

Introduction: There is overwhelming evidence that companies with women on their boards of directors have higher levels of Corporate Social Responsibility. The relation between professional women and collective or organisational responsibility has been widely studied. However, to date there has been little research into the individual attitudes of women towards social responsibility. The purpose of this study is to analyse the differences in attitudes towards social responsibility between men and women in their professional life. Methods: A study sample (N = 524; 347 women; M edad = 37) was assembled using the LinkedIn social media platform and participants, after providing their informed consent, were asked to answer the Professional Social Responsibility Questionnaire. Results: The results showed significant differences in Professional Social Responsibility between men and women, with moderate effect (t (522) = 2.078; p = 0.038; η 2 = 0.191), in favour of women. The women participants scored higher in the dimensions Discovery of Personal Values (t (522) = 2.342; p = 0.020; η 2 = 0.216) and Social Awareness (t (522) = 2.179; p = 0.030; η 2 = 0.201), both with representative effect sizes. Discussion: These results suggest that the greater commitment to Corporate Social Responsibility of companies with women on their boards of directors is due, in part, to the greater individual or personal social responsibility of women. Higher levels of Discovery of Personal Values and Social Awareness amongst women may also result in better decision-making, ultimately accruing to the benefit of the company in terms of its financial results and reputation.
RESUMEN
In this study, a 50 × 50 mm holographic optical element (HOE) with the property of a spherical mirror was recorded digitally on a silver halide photoplate using a wavefront printing method. It consisted of 51 × 96 hologram spots with each spot measuring 0.98 × 0.52 mm. The wavefronts and optical performance of the HOE were compared with those of reconstructed images from a point hologram displayed on DMDs of different pixel structures. The same comparison was also performed with an analog-type HOE for a heads-up display and with a spherical mirror. A Shack-Hartmann wavefront sensor was used to measure the wavefronts of the diffracted beams from the digital HOE and the holograms as well as the reflected beam from the analog HOE and the mirror when a collimated beam was incident on them. These comparisons revealed that the digital HOE could perform as a spherical mirror, but they also revealed astigmatism-as in the reconstructed images from the holograms on DMDs-and that its focusability was worse than that of the analog HOE and the spherical mirror. A phase map, i.e., the polar coordinate-type presentation of the wavefront, could visualize the wavefront distortions more clearly than the reconstructed wavefronts obtained using Zernike polynomials. The phase map revealed that the wavefront of the digital HOE was more distorted than those of the analog HOE and the spherical mirror.
RESUMEN
BACKGROUND: Although most HTLV infections in Spain have been found in native intravenous drug users carrying HTLV-2, the large immigration flows from Latin America and Sub-Saharan Africa in recent years may have changed the prevalence and distribution of HTLV-1 and HTLV-2 infections, and hypothetically open the opportunity for introducing HTLV-3 or HTLV-4 in Spain. To assess the current seroprevalence of HTLV infection in Spain a national multicenter, cross-sectional, study was conducted in June 2009. RESULTS: A total of 6,460 consecutive outpatients attending 16 hospitals were examined. Overall, 12% were immigrants, and their main origin was Latin America (4.9%), Africa (3.6%) and other European countries (2.8%). Nine individuals were seroreactive for HTLV antibodies (overall prevalence, 0.14%). Evidence of HTLV-1 infection was confirmed by Western blot in 4 subjects (prevalence 0.06%) while HTLV-2 infection was found in 5 (prevalence 0.08%). Infection with HTLV types 1, 2, 3 and 4 was discarded by Western blot and specific PCR assays in another two specimens initially reactive in the enzyme immunoassay. All but one HTLV-1 cases were Latin-Americans while all persons with HTLV-2 infection were native Spaniards. CONCLUSIONS: The overall prevalence of HTLV infections in Spain remains low, with no evidence of HTLV-3 or HTLV-4 infections so far.

OBJECTIVES: To describe breakthrough COVID-19 infection in patients who needed hospitalization and the factors associated with poor outcomes. METHODS: We conducted a retrospective study on patients hospitalized with COVID-19 between December 27, 2020, and October 17, 2021, with either a complete vaccination (CV) scheme (diagnosed 2 weeks after the second dose of the Pfizer/Moderna/AstraZeneca or first dose of the Janssen vaccine was administered) or a partial vaccination (PV) scheme. The main outcomes were all-cause mortality and the need for invasive mechanical ventilation (IMV). The baseline factors associated with the outcomes were analyzed by multiple logistic regression to estimate the odds ratios (odds ratio [OR]; 95% confidence interval [CI]). RESULTS: A total of 145 (101 CV) patients were included. The CV subgroup was mainly composed of older males with high comorbidity (Charlson Index ≥3, 72%; immunosuppression, 20%) and with bilateral pneumonia in 63.4%. Limited therapeutic effort (LTE) was agreed upon for 28% of the patients. In the CV subgroup, endotracheal intubation was required in 10.9% of patients, reaching 15.3% when excluding LTE patients; the global mortality was 22.8%, reaching 41.4% in the subgroup with LTE. Although the patients with PV were younger and had fewer comorbidities, the main outcomes did not differ significantly between the CV and PV groups. The predictors of poor outcomes were age ≥ 65 years, confusion, ferritin > 500 mg/L, extensive lung infiltrates, and a Charlson Index ≥ 3. CONCLUSIONS: Patients with CV hospitalized because of breakthrough COVID-19 infection tend to be older persons, with comorbidities, and have a high mortality.

OBJECTIVES: Although only 10% of persons infected with human T-lymphotropic virus type 1 (HTLV-1) may develop virus-associated illnesses over their lifetime, missing the earlier diagnosis of asymptomatic carriers frequently leads to late presentation. METHODS: A nationwide HTLV-1 register was created in Spain in 1989. We examined the main demographics and clinical features at the time of the first diagnosis for more than three decades. RESULTS: A total of 428 individuals infected with HTLV-1 had been reported in Spain until the end of 2021. Up to 96 (22%) individuals presented clinically with HTLV-1-associated conditions, including subacute myelopathy (57%), T-cell lymphoma (34%), or Strongyloides stercoralis infestation (8%). Since 2008, HTLV-1 diagnosis has been made at blood banks (44%) or clinics (56%). Native Spaniards and Sub-Saharan Africans are overrepresented among patients presenting with HTLV-1-associated illnesses suggesting that poor epidemiological and/or clinical suspicion, which led to the late presentation are more frequent in them than carriers from Latin America (LATAM) (31.7% vs 20.4%, respectively; P = 0.015). CONCLUSION: HTLV-1 infection in Spain is frequently diagnosed in patients presenting with characteristic illnesses. Although screening in blood banks mostly identifies asymptomatic carriers from LATAM, a disproportionately high number of Spaniards and Africans are diagnosed too late at the time of clinical manifestations. Expanding testing to all pregnant women and clinics for sexually transmitted infections could help to unveil HTLV-1 asymptomatic carriers.
