Posible enfermedad por IgG4 asociada con alogenosis iatrogénica. Caso clínico / Possible IgG4 disease associated with iatrogenic allogeneic disease. Case report

Presentamos un caso de paciente con alogenosis iatrogénica que tras ser intervenido quirúrgicamente, cursa con pancreatitis aguda de etiología no precisada con valores séricos elevados de inmunoglobulina 4 (IgG4). La asociación con la buena respuesta terapéutica al tratamiento esteroideo unida al antecedente de síndrome autoinmune inflamatorio sistémico inducido por adyuvantes, insuficiencia renal crónica con biopsia que reportó atrofia tubular severa con fibrosis, pseudotumores intestinales, pérdida de peso, diarrea y dolores óseos asociados, hizo pensar que el agente desencadenante de la respuesta inmunológica pudo ser el estímulo que elevó la IgG4 sérica llevando al diagnóstico de posible enfermedad relacionada con IgG4.(AU)

We present a case with iatrogenic allogenosis who, after undergoing surgery, presented acute pancreatitis of unspecified etiology with elevated serum levels of immunoglobulin 4 (IgG4). The association with a good therapeutic response to steroid treatment coupled with a history of adjuvant-induced systemic inflammatory autoimmune syndrome, insufficiency chronic kidney disease with biopsy that reported severe tubular atrophy with fibrosis, intestinal pseudotumors, weight loss, diarrhea and associated bone pain, suggested that the immunogenic agent that triggers the immune response could be the stimulus to raise serum IgG4 leading to the diagnosis of possible IgG4 disease.(AU)

Introducción: La artritis reumatoide es una enfermedad autoinmune de carácter inflamatorio y crónico. La afectación en la esfera sexual es frecuente, compromete a ambos sexos y se relaciona con factores como el dolor, la discapacidad y el consumo de medicamentos. Esta afectación no ha sido suficientemente abordada en la literatura a pesar de su prevalencia, y en Cuba no se han reportado hasta el momento estudios relacionados sobre este tema de investigación. Objetivo: Determinar el impacto de la artritis reumatoide en la sexualidad y su relación en la actividad y la discapacidad. Métodos: Se realizó un estudio monocéntrico, transversal, descriptivo. Se incluyeron los pacientes con un diagnóstico de artritis reumatoide en el período comprendido de septiembre de 2019 a junio de 2021. Se utilizó el cuestionario Qualisex para evaluar el impacto de la artritis reumatoide en la sexualidad. Resultados: En el estudio doscientos veintiséis pacientes fueron incluidos, la media de edad fue de 53,38 años (DE ± 12,22) el 82,7 por ciento fueron mujeres. Al responder el autocuestionario Qualisex el 73,9 por ciento de los sujetos presentaron afectación en la sexualidad. No se estableció una relación significativa entre la afectación en la esfera sexual y el tiempo de evolución. A diferencia de los niveles altos de actividad y discapacidad. Conclusiones: En la población estudiada se presentó afectación en la sexualidad, no obstante, esta no se relacionó con el tiempo de evolución de la artritis reumatoide. Se encontró asociación entre la actividad de la enfermedad y la capacidad funcional con la afectación en la esfera sexual(AU)

Introduction: Rheumatoid arthritis is a chronic, inflammatory autoimmune disease. Disorders in the sexual sphere is frequent, it affects both sexes and it is related to factors such as pain, disability and medication consumption. This condition has not been sufficiently addressed in the literature despite its prevalence and in Cuba no studies related to the topic under study have been reported to date. Objective: To determine the impact of rheumatoid arthritis on sexuality and its relationship with activity and disability. Methods: A monocentric, cross-sectional and descriptive study was carried out on patients with a diagnosis of rheumatoid arthritis, from September 2019 to June 2021. The Qualisex questionnaire was used to evaluate the impact of rheumatoid arthritis on sexuality. Results: Two hundred twenty-six patients were included, the mean age was 53.38 years (SD ± 12.22) and 82.7percent were women. When answering the Qualisex self-questionnaire, 73.9percent of the subjects had effects in their sexuality. No significant relationship was established between the involvement in the sexual sphere and the time of evolution. Conclusions: The impact on sexuality in the studied population was not related to the duration of rheumatoid arthritis. On the other hand, an association was found between disease activity and functional capacity with effects in the sexual sphere(AU)

Effects of lipografts in immune-driven lipoatrophies. Case studies

Lipodystrophy is a pathological condition associated with an abnormal body adipose tissue redistribution. Facial lipoatrophy can be a consequence of congenital, acquired, or involutional. The lipograft is an autologous fat transplant, which constitutes a treatment option that provides volume, tissue regeneration, and advantages in relation to other fillers in autoimmune diseases. The aim is to highlight the filling action and the metabolic effect of facial lipotransfer, due to the grafted adipocytes survival, and the adipose tissue derived stem cells regenerative activity obtained by nano-fat in patients with facial lipoatrophy. Lipoinjection improves the architecture of the new dermis and increases its functional capacity. It is a treatment with autologous tissue (fatty graft) with great efficacy in relation to other alloplastic filler materials capable of exacerbating an inflammatory response mediated by antibody production.

La lipodistrofia es una condición patológica asociada a una redistribución anómala del tejido adiposo en el cuerpo. La lipoatrofia facial puede ser consecuencia de defectos congénitos, adquiridos o involutivos. El lipoinjerto es el trasplante de grasa autógena y constituye una opción de tratamiento que aporta volumen, regeneración tisular y ventajas en relación con otros materiales de relleno en enfermedades autoinmunes. Se busca resaltar la acción de relleno y el efecto metabólico de la lipotransferencia facial, por la supervivencia de los adipocitos injertados y la actividad regenerativa de las células madre provenientes del tejido adiposo obtenidas por nanofat en pacientes con lipoatrofia facial. La lipoinyección mejora la arquitectura de la nueva dermis y aumenta su capacidad funcional, es un tratamiento con tejido autógeno (injerto graso) con gran eficacia en relación con otros materiales de relleno aloplásticos capaces de exacerbar una respuesta inflamatoria mediada por la producción de anticuerpos.

Seroprevalence of anti-SARS-CoV-2 IgG in asymptomatic and pauci-symptomatic people over a 5 month survey in Argentina.

OBJECTIVE: To evaluate the seroprevalence of COVID-19 infection in pauci-symptomatic and asymptomatic people, the associated epidemiological factors, and IgG antibody kinetic over a 5-month period to get a better knowledge of the disease transmissibility and the rate of susceptible persons that might be infected. METHODS: Seroprevalence was evaluated by a cross-sectional study based on the general population of Santa Fe, Argentina (non-probabilistic sample) carried out between July and November 2020. A subgroup of 20 seropositive individuals was followed-up to analyze IgG persistence. For the IgG anti-SARS-CoV-2 antibodies detection, the COVID-AR IgG® ELISA kit was used. RESULTS: 3 000 individuals were included conforming asymptomatic and pauci-symptomatic groups (n=1 500 each). From the total sample, only 8.83% (n=265) presented reactivity for IgG anti-SARS-CoV-2. A significant association was observed between positive anti-SARS-CoV-2 IgG and a history of contact with a confirmed case; the transmission rate within households was approximately 30%. In the pauci-symptomatic group, among the seropositive ones, anosmia and fever presented an OR of 16.8 (95% CI 9.5-29.8) and 2.7 (95% CI 1.6-4.6), respectively (p <0.001). In asymptomatic patients, IgG levels were lower compared to pauci-symptomatic patients, tending to decline after 4 months since the symptoms onset. CONCLUSION: We observed a low seroprevalence, suggestive of a large population susceptible to the infection. Anosmia and fever were independent significant predictors for seropositivity. Asymptomatic patients showed lower levels of antibodies during the 5-month follow-up. IgG antibodies tended to decrease over the end of this period regardless of symptoms.

[RESUMEN]. Objetivo. Evaluar la seroprevalencia de la infección por el virus causante de la COVID-19 en personas paucisintomáticas y asintomáticas, los factores epidemiológicos asociados y la cinética de los anticuerpos IgG durante un período de cinco meses para conocer mejor la transmisibilidad de la enfermedad y la tasa de personas susceptibles a estar infectadas. Métodos. Se evaluó la seroprevalencia mediante un estudio transversal basado en la población general de Santa Fe, Argentina (muestra no probabilística) llevado a cabo entre julio y noviembre del 2020. Se realizó un seguimiento de un subgrupo de 20 personas seropositivas para analizar la persistencia de los anticuerpos IgG. Para la detección de los anticuerpos IgG contra SARS-COV-2, se empleó el kit ELISA COVID-AR IgG®. Resultados. Hubo 3 000 participantes divididos en un grupo asintomático y un grupo paucisintomático (n=1 500 cada grupo). De la muestra total, solo 8,83% (n=265) presentó una reactividad de IgG contra el SARS-CoV-2. Se observó una asociación significativa entre anticuerpos IgG positivos contra el SARS-CoV-2 y antecedente de contacto con un caso confirmado. La tasa de transmisión en el hogar fue de 30% aproximadamente. En el grupo paucisintomático, entre las personas seropositivas, la anosmia y la fiebre presentaron un OR de 16,8 (IC 95% 9,5-29,8) y 2,7 (IC 95% 1,6-4,6), respectivamente (p <0,001). En los pacientes asintomáticos, los niveles de IgG fueron inferiores en comparación con los pacientes paucisintomáticos, con tendencia a la baja pasados cuatro meses desde la aparición de los síntomas. Conclusiones. Se observó una seroprevalencia baja, indicadora de una gran población susceptible a la infección. La anosmia y la fiebre fueron factores predictivos independientes de relevancia para la seropositividad. Los pacientes asintomáticos mostraron niveles inferiores de anticuerpos durante el seguimiento de cinco meses. Los anticuerpos IgG tendieron a disminuir hacia el final del período con independencia de los síntomas.

[RESUMO]. Objetivo. Avaliar a soroprevalência de anticorpos contra a COVID-19 em indivíduos paucissintomáticos e assintomáticos, os fatores epidemiológicos associados e a cinética dos anticorpos da classe IgG em um período de 5 meses, visando aprimorar o conhecimento sobre a transmissibilidade da doença e a taxa de suscetíveis à infecção. Métodos. Inquérito transversal de soroprevalência realizado na população geral (amostra não probabilística) de Santa Fé, na Argentina, entre julho e novembro de 2020. Um subgrupo de 20 indivíduos soropositivos foi acompanhado para analisar a persistência de anticorpos IgG. O kit de ensaio imunoenzimático (ELISA) COVID-AR IgG® foi usado para a detecção de anticorpos IgG contra SARS-CoV-2. Resultados. A amostra compreendeu 3 000 indivíduos, divididos entre assintomáticos e paucissintomáticos (n = 1.500 por grupo). Deste total, somente 8,83% (n = 265) apresentaram reatividade, com a detecção de anticorpos IgG contra SARS-CoV-2. Observou-se uma associação significativa entre a presença de anticorpos IgG contra SARS-CoV-2 e histórico de contato com caso confirmado. A taxa de transmissão intradomiciliar foi de aproximadamente 30%. No grupo paucissintomático, entre os soropositivos, o odds ratio (OR) para anosmia foi de 16,8 (IC 95% 9,5–29,8), e para febre, 2,7 (IC 95% 1,6–4,6) (p <0,001). Os indivíduos assintomáticos apresentaram níveis de IgG mais baixos que os paucissintomáticos, com uma tendência de declínio após 4 meses do início dos sintomas. Conclusões. Observou-se uma soroprevalência baixa de anticorpos contra a COVID-19 na população estudada, o que indica um grande número de pessoas suscetíveis à infecção. Anosmia e febre foram preditores importantes independentes de soropositividade. Os assintomáticos apresentaram níveis mais baixos de anticorpos aos 5 meses de acompanhamento. Houve uma tendência de redução dos anticorpos IgG ao final deste período, independentemente da presença de sintomas.

Introduction: Difficulties are perceived with respect to management of the nursing care process by nursing interns, which limits its application and puts quality of care at risk. Objective: To assess the effectiveness of a training received by interns concerning knowledge and application of the nursing care process. Methods: One-group pretest-posttest pre-experimental study carried out in 2018 at the National Maternal and Perinatal Institute. The population and the sample were 78 and 60 nursing interns, respectively. After the pretest, training was planned and carried out, every four weeks, with twelve groups of five interns each. Then posttest was applied. The Smirnov-Kolmogorov test determined the normality distribution of the data and, according to the variables and observation time, descriptive statistics was applied. Transforming the vigesimal scores into the categories disapproved, fair, good, very good and excellent, the final value of the variables was obtained. The hypothesis test was performed using Student's t test for means of two paired samples. Results: The mean age was 24 years. 86 percent (52) were female. The scores before the intervention were 10.6 ± 1.45 for knowledge and 13.7 ± 1.21 for application. For the posttest application of the nursing care process, such scores were 16.4 ± 1.57 and 17.2 ± 1.64, respectively. Conclusion: The effectiveness of the program was demonstrated by the positive level variation in knowledge about the nursing care process, being from regular to very good. In the application level, it moved from the level regular to good and excellent(AU)

Functional Autoreactive Anti-ß2 Adrenergic Antibodies May Contribute to Insulin Resistance Profile in Patients with Chronic Chagas Disease.

Potential activation of ß2 adrenergic receptors (ß2AR) by specific autoreactive antibodies (Abs) that arise during the host reaction to Trypanosoma cruzi, could contribute to the elevated prevalence of metabolic disturbances described in patients with chronic Chagas disease (CCD). This study aimed to determine the prevalence of anti-ß2AR Abs in patients with CCD, as well as the correlation of these Abs with the presence of glucose and lipid metabolism disturbances, in order to explore their association with an insulin resistance profile. Additionally, we tested the functional effects of anti-ß2AR Abs employing an in vitro bioassay with neuroendocrine cells expressing ß2AR. A clinical and metabolic evaluation including an OGTT was performed in 80 CCD patients and 40 controls. Anti-ß2AR Abs were measured by an in-house-developed ELISA, and the ß2 adrenergic activity of affinity-purified IgG fractions from patient' sera were assayed in CRE-Luc and POMCLuc transfected AtT-20 cells. A higher proportion of dysglycemia (72.5% vs. 37.5%; p = 0.001) was observed in the CCD group, accompanied by increased HOMA2-IR (p = 0.019), especially in subjects with Abs (+). Anti-ß2AR Abs reactivity (7.01 (2.39-20.5); p = 0.0004) and age >50 years (3.83 (1.30-11.25); p = 0.014) resulted as relevant for IR prediction (AUC: 0.786). Concordantly, Abs (+) CCD patients showed elevated metabolic risk scores and an increased prevalence of atherogenic dyslipidemia (p = 0.040), as compared to Abs (-) patients and controls. On functional bioassays, Abs exerted specific and dose-dependent ß2-agonist effects. Our findings suggest that anti-ß2AR Abs may induce the activation of ß2AR in other tissues besides the heart; furthermore, we show that in patients with CCD these Abs are associated with an insulin resistance profile and atherogenic dyslipidemia, providing biological plausibility to the hypothesis that adrenergic activation by anti-ß2AR Abs could contribute to the pathogenesis of metabolic disturbances described in CCD patients, increasing their cardiovascular risk.

Increased epicardial adipose tissue thickness associated with increased metabolic risk and the presence of heart failure in patients with Chronic Chagas disease.

BACKGROUND: It has been described that Trypanosoma cruzi is capable of promoting metabolic disturbances currently considered as cardiovascular risk factors. Moreover, it has been observed that the protozoa can remain in adipose tissue and alter its immune endocrine functions. The aim of this study was to characterize the thickness of epicardial adipose tissue (EAT) in patients with chronic Chagas disease (CCD) concerning their cardiovascular metabolic risk profile compared with those without CCD. METHODS: A cross-sectional study was performed including T. cruzi seropositive individuals categorized according to a standard CCD classification and a matched seronegative control group. Complete clinical examination, metabolic laboratory tests and transthoracic echocardiography to assess cardiac function and to quantify EAT were performed. RESULTS: Fifty-five individuals aged 46.7±11.9 y, 34 with CCD and 21 in the control group, were included. The CCD group presented higher EAT thickness in relation to controls (4.54±1.28 vs 3.22±0.99 mm; p=0.001), which was significantly associated with the presence of insulin resistance (OR=3, 95% CI 1.58 to 5.73; p<0.001). This group presented lower levels of plasmatic adiponectin than controls, especially in those patients with EAT ≥4.5 mm (p=0.005) who also presented with heart failure more frequently (p=0.01). CONCLUSION: In patients with CCD, a higher EAT thickness is observed and is associated with an increased metabolic risk profile indicated mainly by insulin resistance.

Near real-time surveillance of the SARS-CoV-2 epidemic with incomplete data

Designing public health responses to outbreaks requires close monitoring of population-level health indicators in real-time. Thus, an accurate estimation of the epidemic curve is critical. We propose an approach to reconstruct epidemic curves in near real time. We apply this approach to characterize the early SARS-CoV-2 outbreak in two Spanish regions between March and April 2020. We address two data collection problems that affected the reliability of the available real-time epidemiological data, namely, the frequent missing information documenting when a patient first experienced symptoms, and the frequent retrospective revision of historical information (including right censoring). This is done by using a novel back-calculating procedure based on imputing patients dates of symptom onset from reported cases, according to a dynamically-estimated "backward" reporting delay conditional distribution, and adjusting for right censoring using an existing package, NobBS, to estimate in real time (nowcast) cases by date of symptom onset. This process allows us to obtain an approximation of the time-varying reproduction number (Rt) in real-time. At each step, we evaluate how different assumptions affect the recovered epidemiological events and compare the proposed approach to the alternative procedure of merely using curves of case counts, by report day, to characterize the time-evolution of the outbreak. Finally, we assess how these real-time estimates compare with subsequently documented epidemiological information that is considered more reliable and complete that became available later in time. Our approach may help improve accuracy, quantify uncertainty, and evaluate frequently unstated assumptions when recovering the epidemic curves from limited data obtained from public health surveillance systems in other locations.

Congenital chagas disease: Development and assessment of a specific IgM capture-based assay for diagnosis of transmission.

Transplacental transmission by Trypanosoma cruzi (T. cruzi) infection can be effectively treated if parasiticide drugs are administered as early as possible during childhood. Furthermore, an ideal situation would be to diagnose the infection near birth in order to avoid the loss of patients during the subsequent follow-up. These situation are desirable due to the maximum benefit of drugs in early stages which, consequently, implies a relevant contribution to eliminate mother-to-child transmission. However, available techniques for that purpose have limitations as being operator-dependent (microhematocrit), require several months follow-up (IgG detection) or specialized laboratories (PCR). In this study we propose to detect specific IgM antibodies (Ab) by developing a capture-based ELISA employing an improved antigen (Ag) to diagnose the transplacental transmission of T. cruzi, and in consequence, to enhance access to effective treatment. Firstly, a new chimera Ag (CP4) was obtained from the fusion of CP1 and CP3 protein, carrying FRA, SAPA, MAP, TSSAII/V/VI and TcD Ag from T. cruzi. Then, we optimized the assay by capturing IgM Ab with a polyclonal anti-IgM Ab and evaluating three Ag formulations to detect specific IgM bound. The formulations were formed as follows: i) F1: CP1 and CP3; ii) F2: CP1, CP3, B13 and P2ß; iii) F3: by CP4. Detection of Ab-binding Ag was carried out using an anti-His Ab since all Ag were expressed with a His-tag. The evaluation panel consisted of sera from vertically infected children under 1-year-old (6 younger than 15 days, 7 older) and samples from non-infected children of women with chronic Chagas Disease. The ELISA assay employing CP4 showed better performance with notable high sensitivity and specificity (92.3% and 93.9%, respectively). Positive and negative likelihood ratios of the test (15.2 and 0.082) suggest its potential clinical relevance in term of post-test probability of infection. In conclution, we developed a standardized and non-operator dependent test to detect specific anti-T. cruzi IgM Ab. Although increased sample size is needed for its validation, our results indicate that this capture-based technique employing CP4 Ag can certainly improve the diagnosis of connatal infection.

Seroprevalence of anti-SARS-CoV-2 IgG in asymptomatic and pauci-symptomatic people over a 5 month survey in Argentina / Seroprevalencia de anticuerpos IgG contra el SARS-CoV-2 en personas asintomáticas y paucisintomáticas en un estudio de 5 meses en Argentina / Soroprevalência de IgG contra SARS-CoV-2 em indivíduos assintomáticos e paucissintomáticos em um inquérito de 5 meses na Argentina

ABSTRACT Objective. To evaluate the seroprevalence of COVID-19 infection in pauci-symptomatic and asymptomatic people, the associated epidemiological factors, and IgG antibody kinetic over a 5-month period to get a better knowledge of the disease transmissibility and the rate of susceptible persons that might be infected. Methods. Seroprevalence was evaluated by a cross-sectional study based on the general population of Santa Fe, Argentina (non-probabilistic sample) carried out between July and November 2020. A subgroup of 20 seropositive individuals was followed-up to analyze IgG persistence. For the IgG anti-SARS-CoV-2 antibodies detection, the COVID-AR IgG® ELISA kit was used. Results. 3 000 individuals were included conforming asymptomatic and pauci-symptomatic groups (n=1 500 each). From the total sample, only 8.83% (n=265) presented reactivity for IgG anti-SARS-CoV-2. A significant association was observed between positive anti-SARS-CoV-2 IgG and a history of contact with a confirmed case; the transmission rate within households was approximately 30%. In the pauci-symptomatic group, among the seropositive ones, anosmia and fever presented an OR of 16.8 (95% CI 9.5-29.8) and 2.7 (95% CI 1.6-4.6), respectively (p <0.001). In asymptomatic patients, IgG levels were lower compared to pauci-symptomatic patients, tending to decline after 4 months since the symptoms onset. Conclusion. We observed a low seroprevalence, suggestive of a large population susceptible to the infection. Anosmia and fever were independent significant predictors for seropositivity. Asymptomatic patients showed lower levels of antibodies during the 5-month follow-up. IgG antibodies tended to decrease over the end of this period regardless of symptoms.

RESUMEN Objetivo. Evaluar la seroprevalencia de la infección por el virus causante de la COVID-19 en personas paucisintomáticas y asintomáticas, los factores epidemiológicos asociados y la cinética de los anticuerpos IgG durante un período de cinco meses para conocer mejor la transmisibilidad de la enfermedad y la tasa de personas susceptibles a estar infectadas. Métodos. Se evaluó la seroprevalencia mediante un estudio transversal basado en la población general de Santa Fe, Argentina (muestra no probabilística) llevado a cabo entre julio y noviembre del 2020. Se realizó un seguimiento de un subgrupo de 20 personas seropositivas para analizar la persistencia de los anticuerpos IgG. Para la detección de los anticuerpos IgG contra SARS-COV-2, se empleó el kit ELISA COVID-AR IgG®. Resultados. Hubo 3 000 participantes divididos en un grupo asintomático y un grupo paucisintomático (n=1 500 cada grupo). De la muestra total, solo 8,83% (n=265) presentó una reactividad de IgG contra el SARS-CoV-2. Se observó una asociación significativa entre anticuerpos IgG positivos contra el SARS-CoV-2 y antecedente de contacto con un caso confirmado. La tasa de transmisión en el hogar fue de 30% aproximadamente. En el grupo paucisintomático, entre las personas seropositivas, la anosmia y la fiebre presentaron un OR de 16,8 (IC 95% 9,5-29,8) y 2,7 (IC 95% 1,6-4,6), respectivamente (p <0,001). En los pacientes asintomáticos, los niveles de IgG fueron inferiores en comparación con los pacientes paucisintomáticos, con tendencia a la baja pasados cuatro meses desde la aparición de los síntomas. Conclusiones. Se observó una seroprevalencia baja, indicadora de una gran población susceptible a la infección. La anosmia y la fiebre fueron factores predictivos independientes de relevancia para la seropositividad. Los pacientes asintomáticos mostraron niveles inferiores de anticuerpos durante el seguimiento de cinco meses. Los anticuerpos IgG tendieron a disminuir hacia el final del período con independencia de los síntomas.

RESUMO Objetivo. Avaliar a soroprevalência de anticorpos contra a COVID-19 em indivíduos paucissintomáticos e assintomáticos, os fatores epidemiológicos associados e a cinética dos anticorpos da classe IgG em um período de 5 meses, visando aprimorar o conhecimento sobre a transmissibilidade da doença e a taxa de suscetíveis à infecção. Métodos. Inquérito transversal de soroprevalência realizado na população geral (amostra não probabilística) de Santa Fé, na Argentina, entre julho e novembro de 2020. Um subgrupo de 20 indivíduos soropositivos foi acompanhado para analisar a persistência de anticorpos IgG. O kit de ensaio imunoenzimático (ELISA) COVID-AR IgG® foi usado para a detecção de anticorpos IgG contra SARS-CoV-2. Resultados. A amostra compreendeu 3 000 indivíduos, divididos entre assintomáticos e paucissintomáticos (n = 1.500 por grupo). Deste total, somente 8,83% (n = 265) apresentaram reatividade, com a detecção de anticorpos IgG contra SARS-CoV-2. Observou-se uma associação significativa entre a presença de anticorpos IgG contra SARS-CoV-2 e histórico de contato com caso confirmado. A taxa de transmissão intradomiciliar foi de aproximadamente 30%. No grupo paucissintomático, entre os soropositivos, o odds ratio (OR) para anosmia foi de 16,8 (IC 95% 9,5-29,8), e para febre, 2,7 (IC 95% 1,6-4,6) (p <0,001). Os indivíduos assintomáticos apresentaram níveis de IgG mais baixos que os paucissintomáticos, com uma tendência de declínio após 4 meses do início dos sintomas. Conclusões. Observou-se uma soroprevalência baixa de anticorpos contra a COVID-19 na população estudada, o que indica um grande número de pessoas suscetíveis à infecção. Anosmia e febre foram preditores importantes independentes de soropositividade. Os assintomáticos apresentaram níveis mais baixos de anticorpos aos 5 meses de acompanhamento. Houve uma tendência de redução dos anticorpos IgG ao final deste período, independentemente da presença de sintomas.

Lockdown measures and relative changes in the age-specific incidence of SARS-CoV-2 in Spain

BackgroundThe first months of the SARS-CoV-2 epidemic in Spain resulted in high incidence and mortality. A national sero-epidemiological survey suggests higher cumulative incidence of infection in older individuals than in younger individuals. However, little is known about the epidemic dynamics in different age groups, including the relative effect of the lockdown measures introduced on March 15, and strengthened on March 30 to April 14, 2020 when only essential workers continued to work. MethodsWe used data from the National Epidemiological Surveillance Network (RENAVE in Spanish) on the daily number of reported COVID-19 cases (by date of symptom onset) in eleven 5-year age groups: 15-19y through 65-69y. For each age group g, we computed the proportion E(g) of individuals in age group g among all reported cases aged 15-69y during the pre-lockdown period (March 1-10, 2020) and the corresponding proportion L(g) during two lockdown periods (March 25-April 3 and April 8-17, 2020). For each lockdown period, we computed the proportion ratios PR(g)= L(g)/E(g). For each pair of age groups g1,g2, PR(g1)>PR(g2) implies a relative increase in the incidence of detected SARS-CoV-2 infection in the age group g1 compared with g2 for the later vs. early period. ResultsFor the first lockdown period, the highest PR values were in age groups 50-54y (PR=1.21; 95% CI: 1.12,1.30) and 55-59y (PR=1.19; 1.11,1.27). For the second lockdown period, the highest PR values were in age groups 15-19y (PR=1.26; 0.95,1.68) and 50-54y (PR=1.20; 1.09,1.31). ConclusionsOur results suggest that different outbreak control measures led to different changes in the relative incidence by age group. During the first lockdown period, when non-essential work was allowed, individuals aged 40-64y, particularly those aged 50-59y presented with higher COVID-19 relative incidence compared to pre-lockdown period, while younger adults/older adolescents (together with persons aged 50-59y) had increased relative incidence during the later, strengthened lockdown. The role of different age groups during the epidemic should be considered when implementing future mitigation efforts.

A cohort of patients with COVID-19 in a major teaching hospital in Europe

BACKGROUNDSince the confirmation of the first patient infected with SARS-CoV-2 in Spain in January 2020, the epidemic has grown rapidly, with the greatest impact on the Madrid region. This article describes the first 2226 consecutive adult patients with COVID-19 admitted to the La Paz University Hospital in Madrid. METHODSOur cohort included all consecutively admitted patients who were hospitalized and who had a final outcome (death or discharge) in a 1286-bed hospital of Madrid (Spain) from February 25th (first case admitted) to April 19th, 2020. Data was entered manually into an electronic case report form, which was monitored prior to the analysis. RESULTSWe consecutively included 2226 adult patients admitted to the hospital who either died (460) or were discharged (1766). The patients median age was 61 years; 51.8% were women. The most common comorbidity was arterial hypertension (41.3%). The most common symptom on admission were fever (71.2%). The median time from disease onset to hospital admission was 6 days. Overall mortality was 20.7% and was higher in men (26.6% vs 15.1%). Seventy-five patients with a final outcome were transferred to the ICU (3.4%). Most patients admitted to the ICU were men, and the median age was 64 years. Baseline laboratory values on admission were consistent with an impaired immune-inflammatory profile. CONCLUSIONSWe provide a description of the first large cohort of hospitalized patients with COVID-19 in Europe. Advanced age, male gender, the presence of comorbidities and abnormal laboratory values were more common among the patients with fatal outcomes.

Niveles de Burnout y estrategias de afrontamiento en docentes de educación superior / Burnout Levels and Coping Strategies in Higher Education Professors

Introducción: Los educadores y trabajadores de la salud se hallan entre las personas susceptibles a estrés y Burnout Objetivo: Discutir, en base a la literatura científica, los niveles de Burnout y las estrategias de afrontamiento en docentes de educación superior. Métodos: Revisión sistemática de artículos publicados entre 2010 y 2018 en las bases de datos EBSCO host, SCIELO, ERIC, SCIENCE DIRECT, SCOPUS, REDALYC, DOAJ y LILACS. En la estrategia de búsqueda se utilizó el diagrama de flujo Preferred Reporting Items for Systematic Review and Meta-Analyses (PRISMA). Se revisaron 18 artículos (en idiomas español, portugués e inglés) tras aplicar los criterios de inclusión y exclusión. Conclusiones: No queda claro si existe Burnout en los docentes de educación superior. Se asocia levemente niveles altos de agotamiento y despersonalización con alto compromiso laboral; estrés laboral y nivel de agotamiento alto con menor satisfacción laboral; relación entre alto nivel de agotamiento con profesores jóvenes con menos experiencia; agotamiento con factores académicos como horas de enseñanza; Burnout con actividades de investigación; mayor estrés con condición laboral contratado. No se halló relación significativa entre Burnout y sentimientos de autoeficacia o desempeño docente; cansancio emocional y satisfacción ocupacional. Las estrategias para afrontar el estrés que utilizan los docentes son las enfocadas en la solución del problema, la búsqueda de ayuda o apoyo social y la revaluación positiva(AU)

Introduction: Health educators and general workers in the sector are among the people vulnerable to stress and burnout Objective: To discuss, based on the scientific literature, burnout levels and coping strategies in higher education professors. Methods: Systematic review of articles published between 2010 and 2018 in the databases EBSCO host, SCIELO, ERIC, SCIENCE DIRECT, SCOPUS, REDALYC, DOAJ, and LILACS. In the search strategy, the Preferred Reporting Items for Systematic Review and Meta-Analyzes (PRISMA) flowchart was used. Eighteen articles (in Spanish, Portuguese, and English) were reviewed after applying the inclusion and exclusion criteria. Conclusions: It is not clear if burnout exists in higher education professors. High levels of exhaustion and depersonalization are slightly associated with high work commitment. Job stress and high level of exhaustion are associated with less job satisfaction. Relationship between high level of exhaustion is associated with younger professors with less experience. Exhaustion is associated with academic factors such as teaching hours. Burnout is associated with research activities. Increased stress is associated with an employment condition as contracted. No significant relationship was found between burnout and feelings of self-efficacy or teaching performance, or between emotional fatigue and occupational satisfaction. The strategies for dealing with stress that teachers use are those focused on solving the problem, seeking help or social support, and positive revaluation(AU)
