ABSTRACT
Abstract Introduction: Acute kidney injury (AKI) occurs frequently in COVID-19 patients and is associated with greater morbidity and mortality. Knowing the risks of AKI allows for identification, prevention, and timely treatment. This study aimed to identify the risk factors associated with AKI in hospitalized patients. Methods: A descriptive, retrospective, cross-sectional, and analytical component study of adult patients hospitalized with COVID-19 from March 1 to December 31, 2020 was carried out. AKI was defined by the creatinine criteria of the KDIGO-AKI guidelines. Information, regarding risk factors, was obtained from electronic medical records. Results: Out of the 934 patients, 42.93% developed AKI, 60.59% KDIGO-1, and 9.9% required renal replacement therapy. Patients with AKI had longer hospital stay, higher mortality, and required more intensive care unit (ICU) admission, mechanical ventilation, and vasopressor support. Multivariate analysis showed that age (OR 1.03; 95% CI 1.02-1.04), male sex (OR 2.13; 95% CI 1.49-3.04), diabetes mellitus (DM) (OR 1.55; 95% CI 1.04-2.32), chronic kidney disease (CKD) (OR 2.07; 95% CI 1.06-4.04), C-reactive protein (CRP) (OR 1.02; 95% CI 1.00-1.03), ICU admission (OR 1.81; 95% CI 1.04-3.16), and vasopressor support (OR 7.46; 95% CI 3.34-16.64) were risk factors for AKI, and that bicarbonate (OR 0.89; 95% CI 0.84-0.94) and partial pressure arterial oxygen/inspired oxygen fraction index (OR 0.99; 95% CI 0.98-0.99) could be protective factors. Conclusions: A high frequency of AKI was documented in COVID-19 patients, with several predictors: age, male sex, DM, CKD, CRP, ICU admission, and vasopressor support. AKI occurred more frequently in patients with higher disease severity and was associated with higher mortality and worse outcomes.
RESUMO Introdução: Lesão renal aguda (LRA) ocorre frequentemente em pacientes com COVID-19 e associa-se a maior morbidade e mortalidade. Conhecer riscos da LRA permite a identificação, prevenção e tratamento oportuno. Este estudo teve como objetivo identificar fatores de risco associados à LRA em pacientes hospitalizados. Métodos: Realizou-se estudo descritivo, retrospectivo, transversal e de componente analítico de pacientes adultos hospitalizados com COVID-19 de 1º de março a 31 de dezembro, 2020. Definiu-se a LRA pelos critérios de creatinina das diretrizes KDIGO-LRA. Informações sobre fatores de risco foram obtidas de prontuários eletrônicos. Resultados: Dos 934 pacientes, 42,93% desenvolveram LRA, 60,59% KDIGO-1 e 9,9% necessitaram de terapia renal substitutiva. Pacientes com LRA apresentaram maior tempo de internação, maior mortalidade e necessitaram de mais internações em UTIs, ventilação mecânica e suporte vasopressor. A análise multivariada mostrou que idade (OR 1,03; IC 95% 1,02-1,04), sexo masculino (OR 2,13; IC 95% 1,49-3,04), diabetes mellitus (DM) (OR 1,55; IC 95% 1,04-2,32), doença renal crônica (DRC) (OR 2,07; IC 95% 1,06-4,04), proteína C reativa (PCR) (OR 1,02; IC 95% 1,00-1,03), admissão em UTI (OR 1,81; IC 95% 1,04-3,16) e suporte vasopressor (OR 7,46; IC 95% 3,34-16,64) foram fatores de risco para LRA, e que bicarbonato (OR 0,89; IC 95% 0,84-0,94) e índice de pressão parcial de oxigênio arterial/fração inspirada de oxigênio (OR 0,99; IC 95% 0,98-0,99) poderiam ser fatores de proteção. Conclusões: Documentou-se alta frequência de LRA em pacientes com COVID-19, com diversos preditores: idade, sexo masculino, DM, DRC, PCR, admissão em UTI e suporte vasopressor. LRA ocorreu mais frequentemente em pacientes com maior gravidade da doença e associou-se a maior mortalidade e piores desfechos.
ABSTRACT
Introducción: A nivel mundial, la cobertura de vacunación contra el COVID-19, así como contra la influenza es baja tanto en la población general como en los profesionales de la salud a pesar de que la vacuna es gratuita y obligatoria en el personal sanitario. Objetivo: Describir la cobertura de vacunación contra el COVID -19, y la influenza en personal de salud y administrativo de un hospital de referencia del Ministerio de Salud Pública y Bienestar Social en el periodo 2021-2022. Metodología: Estudio observacional descriptivo de corte trasverso. Se hizo la revisión de los registros del personal sanitario y administrativo del centro vacunatorio del Hospital Nacional de Itauguá de la campaña vacunal contra el COVID-19 y de anti-influenza en el periodo 2021- 2022. Resultados: De los 3.586 funcionarios, 999 (27,9 %) eran médicos, 1494 (41,7 %) personal de enfermería, 366 (10,2 %) otra categoría de personal sanitario, y 727 (20,3 %) personal administrativo. En forma global, el 86,5 % de los funcionarios recibió por lo menos las dos dosis que constituyen el esquema primario y el 73 % la dosis de refuerzo. El 2,1 % del personal no recibió ninguna dosis de vacuna anti covid-19, la cifra fue mayor en el personal administrativo (4,8 %). La cobertura de vacunación contra la influenza fue de 20 % en el 2021 y 25 % en el 2022. Discusión: Si bien cobertura de vacunación anti-COVID-19 fue comparable a otros países, la vacunación contra la influenza fue muy baja. Es urgente implementar estrategias dirigidas a aumentar la percepción de riesgo y aceptabilidad de las vacunas obligatorias para el personal sanitario.
Introduction: Worldwide, vaccination coverage against COVID-19, as well as against influenza, is low both in the general population and in health professionals, despite the fact that the vaccine is free and mandatory for health personnel. Objective: To describe the COVID -19 and influenza vaccination coverage in health and administrative personnel of a reference hospital of the Ministry of Public Health and Social Welfare in the period 2021-2022. Methods: Cross-sectional descriptive observational study. Charts of the health and administrative personnel of the vaccination center of the Itauguá National Hospital of the COVID-19 and influenza vaccination campaign in the period 2021-2022 were reviewed. Results: Of the 3,586 personnel, 999 (27.9%) were medical personnel, 1,494 (41.7%) nursing personnel, 366 (10.2%) other category of health personnel, and 727 (20.3%) administrative personnel. Overall, 86.5% of the employees received at least the two doses that constitute the primary schedule and 73% the booster dose; 2.1% of the staff did not receive any dose of the anti COVID-19 vaccine, which was higher in the administrative staff (4.8%). Influenza vaccination coverage was 20% in 2021 and 25% in 2022. Discussion: Even though the vaccination coverage of anti-COVID-19 was comparable to other countries, vaccination anti-influenza was very low. It is urgent to implement strategies aimed at increasing the perception of risk and acceptability of mandatory vaccines for health personnel.
ABSTRACT
Introducción: Estudios previos han reportado que pacientes infectados con el virus del COVID-19, podrían manifestar sintomatologías a nivel de la cavidad oral. Objetivo: Evaluar la frecuencia de manifestaciones orales asociadas a COVID-19 en un segmento de la población paraguaya y determinar cuáles son las más prevalentes. Metodología: Estudio descriptivo de corte transversal. Fue realizada una encuesta electrónica de enero a marzo del 2022. Los datos fueron presentados como frecuencias y porcentajes y analizados mediante la prueba de chi-cuadrado. El análisis estadístico se realizó con el software R versión 4.0.3. Resultados: La muestra estuvo compuesta por 478 personas. El 79,50 % correspondió al sexo femenino y el 45,19 % tenía entre 25 y 34 años. El 65,48 % informó haber experimentado al menos 1 síntoma o signo oral durante el curso de COVID-19. La pérdida de la sensación de sabores amargos, seguida de la alteración del sabor de los alimentos y la pérdida de la percepción dulce, fueron los síntomas más comunes. Se encontró una proporción significativamente mayor de manifestaciones orales en el rango de 18-24 años (χ²; p= 0,003). Entre las personas que desarrollaron COVID-19 de forma moderada a severa hubo mayor número de manifestaciones de síntomas orales (χ²; p= 0,044). Discusión: Se identificó una alta frecuencia de manifestaciones orales en pacientes con casos de moderados a severos de COVID-19, destacándose los trastornos del gusto como los más predominantes. Los individuos más jóvenes fueron los más afectados.
Introduction: Previous studies have reported that patients infected with the COVID-19 virus could manifest symptoms in the oral cavity. Objective: To evaluate the frequency of oral manifestations associated with COVID-19 in a segment of the Paraguayan population and determine the most prevalent ones. Methods: Descriptive cross-sectional study. An electronic survey was conducted from January to March 2022. The data were presented as frequencies and percentages and analyzed using the chi-square test. Statistical analysis was performed with R software version 4.0.3. Results: The sample consisted of 478 individuals. 79.50% were female, and 45.19% were between 25 and 34 years old. 65.48% reported having experienced at least 1 oral symptom or sign during the course of COVID-19. The loss of the sensation of bitter tastes, followed by the alteration of the taste of foods and the loss of sweetness perception, were the most common symptoms. A significantly higher proportion of oral manifestations was found in the 18-24 age range (χ²; p= 0.003). Among people who developed COVID-19 in a moderate to severe form, a greater number of oral symptom manifestations were observed (χ²; p= 0.044). Discussion: A high frequency of oral manifestations was identified in patients with moderate to severe cases of COVID-19, with taste disorders standing out as the most predominant. Younger individuals were the most affected.
ABSTRACT
El objetivo general de los presentes lineamientos es establecer las disposiciones técnicas para la realización de las acciones para continuar la vacunación de la población contra el SARS-CoV-2. La priorización vacunal es una estrategia para proteger poblaciones de riesgo, evitando caer en el error de no vacunar a otros grupos cuyo riesgo puede ser bajo, pero que pueden generar enfermedad severa, complicaciones, hospitalizaciones y muerte asociada a COVID-19. En razón de lo anterior se actualizan los esquemas de vacunación frente a COVID-19, a partir de priorización de grupos poblacionales
The general objective of these guidelines is to establish technical provisions for the implementation of actions to continue the vaccination of the population against SARS-CoV-2. Vaccine prioritization is a strategy to protect at-risk populations, avoiding the error of not vaccinating other groups whose risk may be low, but which can lead to severe disease, complications, hospitalizations and death associated with VOCID-19. In view of the foregoing, vaccination schemes against VOCID-19 are updated, based on the prioritization of population groups

OBJECTIVE: To describe the use of telemedicine by health professionals for diagnosis or treatment of patients during the Covid-19 pandemic. METHOD: This is a systematic literature review of observational studies. Five databases were used. The assessment of the studies methodological quality occurred individually among the revisors and the Joanna Briggs Institute (JBI) tool was used. RESULTS: The reviewers selected 22 articles from 6,180 works. The services provided through telemedicine were consultation/screening, consultation/follow-up or monitoring, test reports, medication prescriptions and case discussions. The technological resources used were platforms using video and telephone (audio and video). The use of telemedicine made it possible to reduce their exposure to Covid-19, reduce social panic and anxiety, quickly medical specialties access and the possibility of access to diagnosis and treatment of patients with chronic and acute diseases. CONCLUSION: Telemedicine can be an important tool in healthcare, keeping patients and healthcare professionals safe during the Covid-19 pandemic.
ABSTRACT
La infección por el virus SARS-CoV-2, conocida como COVID-19, ha causado alta morbilidad y mortalidad en el mundo. Después de haber descifrado el código genético del virus y haber desarrollado un gran trabajo investigativo en la creación de vacunas, con diversas estrategias de acción, se ha logrado disminuir la morbi mortalidad. Fue necesario acelerar el proceso de producción de vacunas, lo cual estuvo facilitado por el avanzado conocimiento científico en el campo de la genética y la virología, para brindar a la especie humana una protección eficaz y segura contra la agresiva y progresiva infección. Las vacunas se clasifican de acuerdo con su mecanismo de acción, existen vacunas basadas en vectores virales que no se replican, vacunas recombinantes, otras basadas en virus atenuados y virus inactivos, y (la gran novedad de la ciencia actual) las vacunas basadas en ARN mensajero y ADN. Estas últimas han demostrado una gran eficacia y seguridad en la prevención de la infección por el SARS-CoV-2, también han impactado de manera fuerte, por lo que han reducido la infección y la mortalidad en la población. En consecuencia, cada día que pasa desde que se inició el periodo de vacunación mundial, se evidencia una reducción en la curva de contagio y mortalidad por COVID-19.
The infection produced by the SARS-CoV-2 virus, known as COVID-19, has caused high morbidity and mortality across the world. After having deciphered the virus's genoma and carried out investigative endeavors that led to the creation of a variety of vaccines with different mechanisms of action, it has been possible to decrease the morbidity and mortality associated with the virus. It was necessary to accelerate the vaccine production process, which was facilitated by advanced scientific knowledge within the disciplines of genetics and virology, in order to provide the human species with a safe and effective form of protection against the aggressive and progressive infection. Vaccines are classified differently depending on their action mechanisms: there are some based on non-replicating viral vectors, recombinant vaccines, ones that are based on attenuated or inactivated viruses, and (the greatest novelty of current scientific developments) vaccines based on DNA and messenger RNA. The latter has demonstrated significant efficacy and safety in the prevention of the SARS-CoV-2 infection as observed in preliminary studies, and they have meaningfully impacted the population by reducing the rates of infection and mortality. As a result, decreased levels of spread of and mortality from COVID-19 have been evidenced across the globe following the beginning of the vaccine distribution period.

Estas últimas demonstraram grande eficácia e segurança na prevenção da infecção por SARS-CoV-2, mas também tiveram um forte impacto, razão pela qual reduziram a infecção e a mortalidade na população. Consequentemente, a cada dia que passa desde o início do período global de vacinação, fica evidente uma redução na curva de contágio e mortalidade por COVID-19.

ABSTRACT Purpose: To evaluate macular chorioretinal flow changes on optical coherence tomography angiography, in participants who received inactivated and messenger RNA (mRNA) vaccines to prevent coronavirus disease 2019 (COVID-19). Methods: In this prospective cohort study, healthy participants who received two doses of an inactivated COVID-19 vaccine (CoronaVac) and then one dose of an mRNA vaccine (BNT162b2) were examined before and after each vaccination. Ophthalmologic examination and imaging with optical coherence tomography angiography were performed during each visit. We evaluated vascular densities in the superficial and deep capillary plexuses in foveal, parafoveal, and perifoveal areas; the foveal avascular zone; and choriocapillaris flows (in 1- and 6-mm-diameter areas). Results: One eye in each of the 24 participants was assessed. Superficial capillary plexus vascular densities in the parafoveal area were significantly lower after the second dose of the CoronaVac vaccine than after the first dose. In the deep capillary plexus, vascular attenuation was observed only in the parafoveal region after the first CoronaVac dose. However, in all regions, the deep capillary plexus vascular densities and subfoveal choriocapillaris flow were significantly decreased after the second CoronaVac dose. After the BNT162b2 dose, the superficial capillary plexus vascular densities, the deep capillary plexus vascular densities, and subfoveal choriocapillaris flow of most regions were significantly lower than those before vaccinations. Conclusion: Vascular attenuation, observed particularly after the second dose of the CoronaVac vaccine, may explain the pathogenesis of postvaccine ocular ischemic disorders reported in the literature. However, these disorders are extremely rare, and the incidence of thrombotic events caused by COVID-19 itself is higher.
ABSTRACT
ABSTRACT. COVID-19 is a multisystem disease caused by the RNA virus (coronavirus 2 or SARS-CoV-2) that can impact cognitive measures. Objective: To identify the main cognitive and neuropsychiatric symptoms in adults who had no cognitive complaints prior to the infection. Specifically, to observe the trajectory of cognitive and neuropsychiatric performance after 6 months. Methods: This is a retrospective longitudinal study. Forty-nine patients (29 reassessed after 6 months), with a positive PCR test, with no prior cognitive complaints that only presented after the infection and without a history of structural, neurodegenerative or psychiatric neurological diseases. A brief cognitive assessment battery (MoCA), the Trail Making Test (TMT-A, B, ∆), and the Verbal Fluency Test were used, as well as the scales (Hospital Anxiety and Depression Scale-HADS, Fatigue Severity Scale-FSS). Correlation tests and group comparison were used for descriptive and inferential statistics. Level of significance of α=5%. Results: Mean age of 50.4 (11.3), 12.7 (2.8) years of education, higher percentage of women (69.8%). No psycho-emotional improvement (depression and anxiety) was observed between the evaluations, and patients maintained the subjective complaint of cognitive changes. The HAD-Anxiety scale showed a significant correlation with TMT-B errors. The subgroup participating in cognitive stimulation and psychoeducation showed improvement in the global cognition measure and the executive attention test. Conclusion: Our results corroborate other studies that found that cognitive dysfunctions in post-COVID-19 patients can persist for months after disease remission, as well as psycho-emotional symptoms, even in individuals with mild infection. Future studies, with an increase in casuistry and control samples, are necessary for greater evidence of these results.
RESUMO. A COVID-19 é uma doença multissistêmica causada pelo vírus RNA (coronavírus 2 ou SARS-CoV-2) que pode ocasionar repercussão em medidas cognitivas. Objetivo: Identificar os principais sintomas cognitivos e neuropsiquiátricos em adultos sem queixas cognitivas anteriores à infecção. Especificamente, verificar a trajetória do desempenho cognitivo e neuropsiquiátrico após 6 meses. Métodos: Trata-se de um estudo retrospectivo e longitudinal. Foram incluídos 49 pacientes (29 reavaliados após 6 meses), com exame de PCR positivo, sem queixas cognitivas prévias que só se apresentaram após a infecção ou histórico de doenças neurológicas estruturais ou neurodegenerativas. Foram utilizados a bateria de avaliação cognitiva breve (MoCA), o Teste de Trilhas (TMT-A, B e ∆) e o Teste de Fluência Verbal; assim como a Escala Hospitalar de Ansiedade e Depressão (HADS), e a escala de Severidade da Fadiga (ESF/BR). Testes de correlação e comparação de grupos foram utilizados para estatística descritiva e inferencial. Esta ocorreu através de. Nível de significância de α=5%. Resultados: idade média de 50,4 anos (11,3), anos de escolaridade 12,7 (2,8), maior proporção de mulheres (69,8%). Não foi observada melhora psicoemocional (depressão e ansiedade) entre as avaliações, assim como os pacientes mantiveram a queixa subjetiva de alteração cognitiva. A escala HAD-Ansiedade apresentou correlação significativa com os erros do TMT-B. O subgrupo que participou da estimulação cognitiva e psicoeducação apresentou melhora na medida de cognição global e no teste de atenção executiva. Conclusão: Nossos resultados corroboram com os demais estudos que constataram que a disfunção cognitiva em pacientes pós-COVID-19 pode persistir por meses após a remissão da doença, assim como sintomas psicoemocionais, mesmo em indivíduos com quadros leves da infecção. Estudos futuros, com aumento de casuística e amostras de controle, são necessários para maior evidência desses resultados.
ABSTRACT
SUMMARY OBJECTIVE: The aim of this study was to evaluate the effects of permanent placental injury due to a severe acute respiratory syndrome coronavirus 2 infection during pregnancy on feto-placental circulation. METHODS: In this cross-sectional study, 83 pregnant women with planned deliveries were divided into two groups according to their severe acute respiratory syndrome coronavirus 2 infection statuses during pregnancy. Their demographic parameters, obstetric histories, and prenatal risks were evaluated. A prenatal fetal Doppler ultrasound examination was performed for all participants, and umbilical artery and middle cerebral artery Doppler parameters were obtained. Postpartum placentas were examined for pathological findings under appropriate conditions. All placentas were evaluated according to the Amsterdam consensus criteria. Mann-Whitney U test, Student's t-test, and chi-square test were used for comparisons. RESULTS: Demographic parameters were statistically similar, except that they were borderline significant for gestational weeks at delivery (p=0.044). In the pathological examination of the placenta, regardless of the trimester of exposure to viral infection, perivillous fibrin deposition and villus dystrophic calcification were more common in group 2 (p=0.016 and p=0.048, respectively) than in group 1. In the prenatal Doppler examination between the groups, no statistically significant difference was found for all of the umbilical artery pulsatile index, middle cerebral artery pulsatile index, and cerebro-placental ratio values. CONCLUSION: Severe acute respiratory syndrome coronavirus 2 infection during pregnancy causes an increase in perivillous fibrin deposition and villus dystrophic calcification in the placenta. Placental injury caused by the severe acute respiratory syndrome coronavirus 2 virus does not affect fetal Doppler parameters.
ABSTRACT
SUMMARY OBJECTIVE: The coronavirus disease 2019 pandemic that has emerged recently has significantly affected and continues to affect our lives. The Severe Acute Respiratory Syndrome Coronavirus 2 virus has significant effects on women's health due to gender-related physiological differences. The aim of this study was to compare the menstrual cycle status of young women according to their status of having had coronavirus disease 2019. METHODS: This descriptive cross-sectional study was conducted with 220 young women aged between 18 and 25 years who received at least one dose of coronavirus disease 2019 vaccine. The study data were collected as a survey on the online platform. RESULTS: The descriptive characteristics of young women who had had and had not had coronavirus disease 2019 were distributed homogeneously between the groups (p>0.05). Furthermore, there was no statistical difference in terms of menstrual cycle patterns (p>0.05). The mean scores from the Premenstrual Syndrome Scale and its subscales and the mean scores from the COVID Stress Scale and its subscales were similar in both groups, and no statistically significant difference was identified (p>0.05). CONCLUSION: Although menstrual cycle irregularities due to coronavirus disease 2019 have been reported, these effects are usually observed during the pandemic. A decrease in stress and anxiety with the end of the pandemic may explain the return of the menstrual cycle to normal.
ABSTRACT
ABSTRACT Currently, there are some concerns about the situation and, in particular, about the future of the COVID-19 pandemic and the new emerging variants of SARS-CoV-2. Rodents are an example of synanthropic animals in urban environments that harbor important zoonoses. Although the molecular identification of SARS-CoV-2 in Rattus norvegicus from New York City had been reported, in other studies, urban wild rodents infected with this virus have not been found. This study aimed to molecularly identify the presence of SARS-CoV-2 in urban wild rodents from Mexico City, trapped along a water channel of a public park as part of a pest control program, at the beginning of the COVID-19 pandemic, during the fall and winter of 2020. Up to 33 Mus musculus and 52 R. norvegicus were captured and euthanized, large intestine samples with feces from the animals were obtained. RNAs were obtained and subjected to qRT-PCR for SARS-CoV-2 identification and threshold cycle (Ct) values were obtained. Four mice (12.1%) and three rats (5.8%) were positive, three rodents exhibited Ct<30. Our results on the frequency of SARS-CoV-2 in urban rats are in line with other previous reports. Thus, similar to other authors, we suggest that surveillance for the detection of SARS-CoV-2 in urban wild rodents, as sentinel animals, should be maintained.
ABSTRACT
ABSTRACT Previously considered saprobe and non-pathogenic, the fungus Papiliotrema laurentii (formerly known as Cryptococcus laurentii), is rarely associated with human infection. Nevertheless, there has been an increase in reported infections by non-neoformans cryptococci. After a literature search on the Cochrane Library, LILACS, SciELO, MEDLINE, PubMed, and PMC (PubMed Central) databases, we conclude that this is the first case report of fungemia and probable meningitis caused by Papiliotrema laurentii in a previously immunocompetent host with associated COVID-19.
ABSTRACT
ABSTRACT Human Rabies (HR) is a fatal zoonotic disease caused by lyssaviruses, with the rabies virus (RABV) identified as the causative agent. While the incidence of HR transmitted by dogs has decreased in Latin America, there has been a corresponding rise in transmission via wild animals. Given the lack of effective treatments and specific therapies, the management of HR relies on the availability of post-exposure prophylaxis and animal control measures. This review examines the dynamics and spread of HR during the global pandemic.
ABSTRACT
ABSTRACT This report was aimed at presenting a case of neurotrophic keratitis and concomitant SARS-CoV-2 infection in a patient who has recently undergone a corneal DALK transplant. One month after corneal transplantation with adequate corneal epithelialization, the patient presented neurotrophic keratitis with a torpid course of the corneal transplant coinciding with a SARS-CoV-2 infection, with an excessive host immune response. In addition, the patient presented a re-positivization of nasopharyngeal polymerase chain reaction of SARS-CoV-2 with past disease after starting treatment with autologous serum eye drops. The implications at the ophthalmological level of SARS-CoV-2 infection may be clarified as the time the illness progresses and we learn more about how it acts. In this case, the disparity of signs and symptoms, the antecedent of corneal surgery, and the possibility of a herpetic infection as a cause of the primary leukoma suggested neurotrophic keratitis. Nonetheless, the involvement of systemic SARS-CoV-2 infection in the process, triggering an excessive host immune response at the corneal level with an increase in inflammatory cytokines must be taken into account. No relationship was found between treatment with autologous serum and re-positivization of nasopharyngeal polymerase chain reaction, presenting the patient a favorable response to treatment.
RESUMO O objetivo deste relato foi apresentar um caso de ceratite neurotrófica e infecção concomitante por SARS-CoV-2 em paciente submetido recentemente a transplante de córnea DALK. Um mês após o transplante de córnea com adequada epitelização da córnea, o paciente apresentou ceratite neurotrófica com curso tórpido do transplante de córnea, coincidindo com infecção por SARS-CoV-2, com resposta imune excessiva do hospedeiro. Além disso, o paciente apresentou repositivização da reação em cadeia da polimerase nasofaríngeo de SARS-CoV-2, com doença pregressa após iniciar tratamento com colírio de soro autólogo. As implicações a nível oftalmológico da infecção por SARS-CoV-2, podem ser esclarecidas à medida que a doença progride e aprendemos mais sobre sua forma de atuação. Neste caso, a disparidade de sinais e sintomas, o antecedente de cirurgia de córnea e a possibilidade de infecção herpética como causa do leucoma primário sugeriram ceratite neurotrófica. No entanto, deve-se levar em consideração o envolvimento da infecção sistêmica por SARS-CoV-2 no processo, desencadeando uma resposta imune excessiva do hospedeiro no nível da córnea, com aumento de citocinas inflamatórias. Não foi encontrada relação entre o tratamento com soro autólogo e a repositivização da reação em cadeia da polimerase nasofaríngea, apresentando ao paciente uma resposta favorável ao tratamento.
ABSTRACT
Resumo Objetivo Descrever a prevalência de lesão renal aguda em adultos jovens com diagnóstico da COVID-19 admitidos em unidade terapia intensiva. Métodos Estudo retrospectivo, quantitativo e analítico. A amostra foi de adultos jovens (20 a 40 anos) admitidos em unidades de terapia intensiva, com diagnóstico de infecção por SARS-CoV-2 entre março e dezembro de 2020. Os dados foram obtidos por meio do prontuário eletrônico, e a lesão renal aguda foi definida pelo valor da creatinina, segundo critérios das diretrizes da Kidney Disease Improving Global Outcomes. A significância estatística foi de p≤0,05. Resultados Foram internados 58 adultos jovens, sendo 63,8% do sexo masculino. A hipertensão arterial sistêmica esteve presente em 39,6%, a obesidade em 18,9% e o diabetes mellitus em 8,6%. A lesão renal aguda foi identificada em 55,1%, sendo o estágio 3 predominante em 43,1% deles. Nesses pacientes, o uso de ventilação mecânica e de drogas vasoativas foi significativo em 92%, assim como a disfunção orgânica respiratória (80%), seguida da renal (76%). Fatores de risco, como transplante renal ou doença renal crônica e obesidade, aumentaram em 12,3 e 9,0 vezes, respectivamente, a chance de desenvolver lesão renal aguda. Conclusão Este estudo demonstrou alta prevalência de lesão renal em adultos jovens e sua associação com comorbidades prévias. Obesidade, transplante renal e doença renal crônica elevaram a chance de o adulto jovem desenvolver lesão renal aguda, resultando em desfechos a favor da morbimortalidade.

Abstract Objective To describe acute kidney injury prevalence in young adults diagnosed with COVID-19 admitted to the Intensive Care Unit. Methods This is a retrospective, quantitative and analytical study. The sample consisted of young adults (20 to 40 years old) admitted to Intensive Care Units, diagnosed with SARS-CoV-2 infection between March and December 2020. Data were obtained through electronic medical records, and kidney injury acute was defined by the creatinine value, according to the Kidney Disease Improving Global Outcomes guidelines criteria. Statistical significance was p≤0.05. Results A total of 58 young adults were hospitalized, 63.8% of whom were male. Hypertension was present in 39.6%, obesity in 18.9%, and diabetes mellitus in 8.6%. Acute kidney injury was identified in 55.1%, with stage 3 predominating in 43.1% of them. In these patients, the use of mechanical ventilation and vasoactive drugs was significant in 92% as well as respiratory organ dysfunction (80%), followed by renal organ dysfunction (76%). Risk factors such as kidney transplantation or chronic kidney disease and obesity increased by 12.3 and 9.0 times, respectively, the chances of developing acute kidney injury. Conclusion This study demonstrated a high kidney injury prevalence in young adults and its association with previous comorbidities. Obesity, kidney transplantation and chronic kidney disease increased the chance of young adults to develop acute kidney injury, resulting in outcomes in favor of morbidity and mortality.
ABSTRACT
ABSTRACT Objective: To verify the COVID-19 clinical characteristics, associated comorbidities, and outcomes in adolescents. Data source: This is a systematic review study based on articles published between 2020 and 2022 in the United States National Library of Medicine - PubMed (MedLine), Virtual Health Library - VHL (LILACS), Science Direct, Web of Science, and Scopus (Elsevier) databases. The study was registered in the International Prospective Register of Systematic Reviews, under No. CRD42022309108. Data synthesis: A total of 1188 studies were identified. After applying the selection criteria, 13 articles were included. Prevalence was 25%; mild cases were predominant; and fever, cough, headache, anosmia, nasal congestion, and ageusia were frequent. Fever and cough were proportionally higher in hospitalized cases: 81 and 68%, respectively. Dyspnea (odds ratio [OR] 6.3; confidence interval 95%[CI] 2.8-14.3), fever (OR 3.8; 95%CI 2.0-7.4), and cough (OR 3.4; 95%CI 2.0-6.0) were associated with severe cases. Up to 28% required intensive care and 38% required mechanical ventilation. Pre-existing comorbidities increased the risk of hospitalization and death. Severe cases were associated with the risk of death (relative risk [RR] 4.6; 95%CI 2.8-7.5). The black, mixed, and indigenous races/skin colors represented risk groups, as well as residents of poorer regions. Conclusions: The review provided a better understanding of the disease profile and may favor the development of public policies, in addition to contributing to the current literature in the field of adolescent health.

Fontes de dados: Trata-se de uma revisão sistemática elaborada com base em artigos publicados entre 2020 e 2022 nas bases de dados United States National Library of Medicine (PubMed), Biblioteca Virtual em Saúde (BVS), Science Direct, Web of Science e Scopus. O estudo foi registrado no International Prospective Register of Systematic Reviews, n° CRD42022309108. Síntese dos dados: Foram identificados 1.188 estudos. Após a aplicação dos critérios de seleção, 13 artigos foram incluídos. A prevalência foi de 25%; os casos leves foram predominantes; e febre, tosse, cefaleia, anosmia, congestão nasal e ageusia foram frequentes. Febre e tosse foram proporcionalmente maiores em casos hospitalizados, com 81 e 68%, respectivamente. Dispneia (OR 6,3; IC95% 2,8-14,3), febre (OR 3,8; IC95% 2,0-7,4) e tosse (OR 3,4; IC95% 2,0-6,0) foram associados a casos graves. Até 28% necessitaram de cuidados intensivos e 38% de ventilação mecânica. A preexistência de comorbidade aumentou o risco de internação e óbito. Os casos graves estão associados ao risco de óbito (risco relativo — RR 4,6; IC95% 2,8-7,5). As raças/cores preta, parda e indígena e os moradores de regiões mais pobres foram grupo de risco. Conclusões: A revisão permitiu conhecer o perfil da doença e poderá favorecer a elaboração de políticas públicas, além de contribuir para a literatura atual no campo da saúde do adolescente.
ABSTRACT
ABSTRACT Purpose: This study aimed to evaluate the pre-sence of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) RNA in the ocular surface of individuals clinically suspected of coronavirus disease 2019 (COVID-19) and determine the accuracy of different approaches of molecular testing on the ocular surface based on the nasopharyngeal positivity status for COVID-19. Methods: A total of 152 individuals with suspected COVID-19 symptoms who simultaneously underwent nasopharyngeal and two different tear film collection techniques for quantitative reverse-transcriptase polymerase chain reaction (RT-qPCR) were included. Tears were collected and randomized: one eye had the filter strip for the Schirmer test and the contralateral eye had conjunctival swab/cytology in the inferior fornix. All patients underwent slit lamp biomicroscopy. The accuracy of various ocular surface collection techniques used for the detection of SARS-CoV-2 RNA was determined. Results: Of the 152 patients enrolled in the study, 86 (56.6%) had COVID-19 confirmed by nasopharyngeal PCR. Both tear film collection techniques detected viral particles: the Schirmer test was positive in 16.3% (14/86) and the conjunctival swab/cytology in 17.4% (15/86), with no statistically significant differences. No positive ocular tests were found among those with negative nasopharyngeal PCR tests. The overall agreement of the ocular tests was 92.7%, and in combination, the sensitivity would increase to 23.2%. The mean cycle threshold values in the nasopharyngeal, Schirmer, and conjunctival swab/cytology tests were 18.2 ± 5.3, 35.6 ± 1.4, and 36.4 ± 3.9, respectively. Compared with the nasopharyngeal test, the Schirmer (p=0.001) and conjunctival swab/cytology (p<0.001) tests had significantly different Ct values. Conclusion: The Schirmer (16.3%) and conjunctival swab (17.4%) tests were comparably capable of detecting SARS-CoV-2 RNA in the ocular surface by RT-PCR accurately based on nasopharyngeal status and demonstrated indistinct sensitivity and specificity. Simultaneous specimen sampling and processing from the nasopharyngeal, Schirmer, and conjunctival swab/cytology tests demonstrated significantly lower viral load in both ocular surface approaches than in the nasopharyngeal test. Ocular manifestations detected by slit lamp biomicroscopy were not associated with ocular RT-PCR positivity.
RESUMO Objetivo: Avaliar a presença de RNA de coronavírus 2 causador de síndrome respiratória aguda grave (SARS-CoV-2) na superfície ocular de indivíduos clinicamente suspeitos com COVID-19 e determinar a precisão de diferentes abordagens de testes moleculares na superfície ocular com base no status de positividade do RT-qPCR de nasofaringe para COVID-19. Métodos: 152 indivíduos com sintomas suspeitos para a COVID-19 foram submetidos a coleta de reação em cadeia da polimerase de nasofaringe simultaneamente a duas técnicas diferentes de coleta de filme lacrimal para RT-qPCR: aleatoriamente, um olho com a tira filtro do teste de Schirmer e, o olho contralateral, com citologia (swab) conjuntival no fórnice inferior. Todos os indivíduos foram submetidos à biomicroscopia com lâmpada de fenda. Resultados: Dos 152 pacientes, 86 (56,6%) tiveram a COVID-19 confirmada por PCR de nasofaringe. Ambas as técnicas de coleta detectaram partículas virais: o teste de Schirmer foi positivo em 16,3% (14/86) e a citologia conjuntival em 17,4% (15/86), sem diferenças estatisticamente significativas. Não houve testes oculares positivos entre aqueles com reação em cadeia da polimerase de nasofaringe negativo. A concordância geral dos testes oculares foi de 92,7% e, em combinação, a sensibilidade aumentaria para 23,2%. Os valores médios do limiar de ciclo nos testes de nasofaringe, Schirmer e citologia conjuntival foram 18,2 ± 5,3, 35,6 ± 1,4 e 36,4 ± 3,9, respectivamente. Conclusão: Os testes de Schirmer (16,3%) e swab conjuntival (17,4%) foram igualmente capazes de detectar RNA de SARS-CoV-2 na superfície ocular por RT-PCR e demonstraram sensibilidade e especificidade indistintas. A coleta simultânea de amostras ao processamento dos testes de RT-PCR de nasofaringe, Schirmer e citologia (swab) conjuntival demonstraram carga viral significativamente menor em ambas as abordagens da superfície ocular em comparação com o teste de nasofaringe. As manifestações oculares detectadas pela biomicroscopia com lâmpada de fenda não foram claramente associadas à positividade do RT-PCR ocular.
ABSTRACT
Abstract Objective In this systematic review (SR), the authors aimed to identify the possible impact of the social restriction imposed by the Coronavirus Disease-19 (COVID-19) pandemic on children/adolescents with Attention Deficit Hyperactivity Disorder (ADHD). Data sources This SR was registered on PROSPERO CRD42021255569. Eligible articles were selected from PubMed, Embase, and LILACS, according to the following characteristics: ADHD patients < 18 years old, exposed to the COVID-19 pandemic, and the outcomes, medications, relationships, sleep, media use, remote learning, and comorbidities such as depression/sadness, inattention, anxiety, and irritability/aggressiveness. Newcastle-Ottawa Scale (NOS) for cohort, cross-sectional and case-control studies was used to assess methodological quality and the risk of bias. Summary of findings Of the 222 articles identified, 27 were included, with information on 7,235 patients. Most studies (n = 22) were cross-sectional and received a mean NOS 4.63/10 followed by longitudinal (n = 4) with 3.75/8 points and case-control (n = 1), with 3/9 points. The pandemic affected patients' access to treatment, behavior, and sleep. Difficulties in remote learning and increased use of social media were described, as well as significant and positive changes in relationships with family and peers. Conclusion Although the studies were heterogeneous, they indicated that the pandemic-related issues experienced by patients with ADHD were mostly manifested affecting their behavior and sleep patterns.
ABSTRACT
ABSTRACT Objective: This study aimed to describe the clinical characteristics of the pediatric population with COVID-19 in an Emergency Department (ED) of a Brazilian general hospital. Methods: Epidemiological and clinical data of patients younger than 20 years old were collected from patients' medical records from February 2020 to July 2021. Most of the epidemiological data described pertains to hospitalized patients. We also reviewed coinfections, treatment, and outcomes and compared the first and second waves of COVID-19. Results: We identified a total of 1303 episodes of SARS-CoV-2 infection. The median time from symptom onset to diagnosis was three days. Symptoms were present in 92.3% of the patients. The most common symptoms were fever (45.2%), nasal congestion/discharge (44.2%), and cough (39.4%). Chest radiography and tomography were performed in 7.7 and 3.3% of cases, with abnormal findings in 29.7 and 53.4%, respectively. Hospital admissions occurred in 3.5% of patients, mainly in the presence of comorbidities, in children under five years old and in those who presented to the ED during the first wave of COVID-19. Coinfection with a viral agent was identified in 20% of the 71 cases tested in this study, and a positive rapid test for Streptococcus pyogenes was found in 8% of the 174 cases tested, with no impact of these coinfections on hospitalization. Conclusions: We found that COVID-19 was a mild disease in most children in our study population, with most hospitalizations and readmissions occurring during the first wave of COVID-19.
RESUMO Objetivo: Este estudo teve como objetivo descrever as características clínicas da população pediátrica com COVID-19 no setor de emergência de um hospital geral brasileiro. Métodos: Os dados epidemiológicos e clínicos de pacientes idade inferior a 20 anos foram coletados dos prontuários dos pacientes de fevereiro de 2020 a julho de 2021. A maior parte dos dados epidemiológicos descritos refere-se a pacientes hospitalizados. Também foram revisados as coinfecções, o tratamento e os desfechos de internação e comparadas a primeira e a segunda ondas de COVID-19. Resultados: Foi identificado o total de 1.303 episódios de infecção por SARS-CoV-2. A mediana de tempo desde o início dos sintomas até o diagnóstico foi de três dias. Os sintomas estiveram presentes em 92,3% dos pacientes. Os sintomas mais comuns foram febre (45,2%), congestão/secreção nasal (44,2%) e tosse (39,4%). Radiografia e tomografia de tórax foram realizadas em 7,7 e 3,3% dos casos, com achados anormais em 29,7 e 53,4%, respectivamente. As internações hospitalares ocorreram em 3,5% dos pacientes, principalmente na presença de comorbidades, em crianças menores de cinco anos e naqueles que se apresentaram no pronto-socorro durante a primeira onda de COVID-19. Foi identificada coinfecção viral em 20% dos 71 casos testados e teste rápido positivo para Streptococcus pyogenes em 8% dos 174 casos testados, não havendo impacto dessas coinfecções quanto à internação hospitalar. Conclusões: Observamos que a COVID-19 foi uma doença leve na maioria das crianças de nossa população, com a maior parte das hospitalizações e readmissões ocorrendo durante a primeira onda de COVID-19.
ABSTRACT
Resumo Objetivo Identificar o perfil de nascimentos das gestações de mulheres com acesso à internet que cursaram com a infecção pelo SARS-CoV-2 e seus desfechos. Métodos Estudo transversal integrado a uma coorte prospectiva, com coleta entre agosto de 2021 e fevereiro de 2022, baseado nas respostas de 304 mulheres que tiveram gestações e/ou partos durante o período pandêmico. Resultados Do total, 25,7% das entrevistadas tiveram COVID-19, com predomínio de diagnósticos no terceiro trimestre. Queixas de anosmia, fadiga e cefaleia prevaleceram como relacionados à infecção. As variáveis: utilizar o Sistema Único de Saúde para atendimento (p = 0,084); diabetes gestacional (p = 0,141); baixo peso de nascimento (p = 0,117); necessidade de internação em unidade neonatal (p = 0,120) foram inseridas no modelo de regressão por terem valores de p inferiores a 0,20. A variável referente ao tipo de parto (p=1,000) foi inserida no modelo por se tratar de uma variável de interesse e com descrição de relevância na literatura. A prematuridade foi a única variável que apresentou associação estatística com a infecção pelo SARS-CoV-2 durante a gestação (p = 0,008) na análise bivariada, explicando o desfecho da infecção na gestação (<0,001), comprovado no modelo de Regressão Robusta de Poisson. Conclusão Observou-se alta prevalência de COVID-19 na amostra, com variação de sintomas e predomínio de partos operatórios. No entanto, a infecção pelo SARS-CoV-2 explicou apenas a maior ocorrência de nascimentos prematuros.
Resumen Objetivo Identificar el perfil de nacimientos de los embarazos de mujeres con acceso a internet que lo cursaron con la infección por SARS-CoV-2 y sus desenlaces. Métodos Estudio transversal integrado a una cohorte prospectiva, con recopilación entre agosto de 2021 y febrero de 2022, basado en las respuestas de 304 mujeres que tuvieron embarazos o partos durante el período pandémico. Resultados Del total, el 25,7 % de las entrevistadas tuvieron COVID-19, con predominio de diagnósticos en el tercer trimestre. Prevalecieron quejas de anosmia, fatiga y cefalea como relacionadas a la infección. Las variables utilización del Sistema Único de Salud para atención (p = 0,084), diabetes gestacional (p = 0,141), bajo peso de nacimiento (p = 0,117), necesidad de internación en unidad neonatal (p = 0,120) se introdujeron en el modelo de regresión por tener valores de p inferiores a 0,20. Se introdujo la variable relacionada al tipo de parto (p = 1,000) en el modelo por tratarse de una variable de interés y con descripción de relevancia en la literatura. La prematuridad fue la única variable que presentó asociación estadística con la infección por SARS-CoV-2 durante el embarazo (p = 0,008) en el análisis bivariado, lo que explica el desenlace de la infección en el embarazo (>0,001), comprobado en el modelo de regresión robusta de Poisson. Conclusión Se observó alta prevalencia de COVID-19 en la muestra, con variación de síntomas y predominio de partos operatorios. Sin embargo, la infección por SARS-CoV-2 explicó solamente la mayor incidencia de nacimientos prematuros.
Abstract Objective Identify the profile of births of pregnancies of women with internet access who were infected with SARS-CoV-2 and their outcomes. Methods Cross-sectional study integrated into a prospective cohort, with collection between August 2021 and February 2022, based on the responses of 304 women who had pregnancies and/or deliveries during the pandemic period. Results Of the total, 25.7% of the interviewees had COVID-19, with a predominance of diagnoses in the third quarter. Complaints of anosmia, fatigue and headache prevailed as related to the infection. The variables using the Unified Health System for care (p = 0.084); gestational diabetes (p = 0.141); low birth weight (p = 0.117); need for admission to a neonatal unit (p = 0.120) were included in the regression model because they had p values lower than 0.20. The variable referring to the type of delivery (p=1.000) was inserted in the model because it is a variable of interest and with a description of relevance in the literature. Prematurity was the only variable that was statistically associated with SARS-CoV-2 infection during pregnancy (p = 0.008) in the bivariate analysis, explaining the outcome of infection during pregnancy (<0.001), confirmed in the Poisson Robust Regression model. Conclusion There was a high prevalence of COVID-19 in the sample, with varying symptoms and a predominance of operative deliveries. However, SARS-CoV-2 infection only explained the higher occurrence of premature births.
