Memory impairment and concentration problems in COVID-19 survivors 8 weeks after non-ICU hospitalization: A retrospective cohort study.

Studies on the severe acute respiratory syndrome coronavirus 1 have shown long-term effects on health, rehabilitation, and quality of life in patients.To evaluate effects on recovery and mental health in COVID-19 survivors.A single center, retrospective cohort study in (non-ICU admitted) adult patients with COVID-19 infection was conducted. Next to baseline characteristics during hospital admission, data on remaining symptoms and radiographic abnormalities were extracted at the 8-week follow-up at the outpatient clinic. The Hospital Anxiety and Depression Scale (HADS) was used to detect anxiety and depression.Resulting in two hundred and eleven patients were included, median age of 63 years, 61% male, with overweight (average body mass index 28.6 kg/m2 ). At the outpatient clinic 13% of the patients were symptom free, whereas 25% reported more than three symptoms. Persisting physical symptoms were mainly fatigue 68%, dyspnea 56%, and cough 26%. Most patients had normalization of chest X-ray (61.1%) and oxygen saturation (89.9%). Interestingly, 33% reported memory impairment and concentration problems 28%. 7.8% scored for anxiety and 7.1% for depression on the HADS. Correlations were found between the number of physical symptoms and scores on the HADS.In conclusion, only 13% had symptom-free recovery after 8 weeks. Besides physical symptoms memory problems were frequently seen. The number of mental and physical symptoms were correlated.

Integrating healthcare for follow-up of adult COVID-19 patients in an outpatient clinic: A matter of cooperation.

RATIONALE AIMS AND OBJECTIVES: A large number of patients infected with SARS-CoV-2 (COVID-19) need outpatient follow-up after hospitalization. As these patients may experience a broad range of symptoms, as do patients infected with the related SARS-CoV-1 virus, we set up a multidisciplinary outpatient clinic involving pulmonologists, internists, and geriatricians. Patients were allocated to a specialist based on symptoms reported on a self-developed questionnaire of expected symptoms of COVID-19. This study aimed to evaluate the effectiveness of this outpatient clinic. METHODS: In this retrospective study, the medical records of patients who presented to the outpatient clinic for follow-up after hospitalization for COVID-19 up to 31 August 2020, were reviewed. RESULTS: In total, 266 patients were seen at the outpatient clinic at least once. Overall, 100 patients were seen by a pulmonologist, 97 by an internist, and 65 by a geriatrician. A referral between these 3 medical specialists was needed for only 14 patients (5.3%). Fifty patients were seen by a psychologist, mostly those with a HADS score >10. Only 5 (2.2%) of the 221 patients who were not directly referred to a psychologist based on triage needed psychological support. Forty-eight patients (18%) were also seen by a physiatrist. CONCLUSION: Identifying which medical specialist (pulmonologist, internist, and/or geriatrician) should see patients attending a post-COVID outpatient clinic based on patient-reported symptoms proved an effective approach to managing the flow of post-COVID patients.

[Avoidability of fetal deaths: reflections on the Brazilian List of Avoidable Causes of Deaths through interventions by the Brazilian Unified National Health System]. / Evitabilidade de óbitos fetais: reflexões sobre a Lista Brasileira de Causas de Mortes Evitáveis por intervenção do Sistema Único de Saúde.

Although the Brazilian List of Avoidable Causes of Deaths (LBE in Portuguese), in its version for children under 5 years of age (LBE < 5), does not include stillbirths, some studies have used the list with or without adaptations. We present a proposal for adaptation of the LBE for stillbirths (LBE-OF in Portuguese) and the results of its application to stillbirths in the State of Rio de Janeiro, Brazil, in 2018, compared to the results with LBE < 5. We reviewed the categories from the 10th revision of the International Classification of Diseases (ICD-10) in the LBE < 5 and reassigned them in the avoidability groups, according to time of death in relation to delivery and the causes consistent with stillbirths. Conditions that did not elucidate the determinants of death were allocated as ill-defined causes. Stillbirths in the State of Rio de Janeiro, selected from the databases of the Mortality Information System (SIM in Portuguese), were classified according to LBE-OF and LBE < 5. When classifying the 2,585 stillbirths that occurred in the State of Rio de Janeiro in 2018, we found that according to LBE < 5, there were predominantly causes "reducible by adequate care in labor and delivery" (42.9%), while according to LBE-OF, the most frequent causes were "reducible by adequate care for during pregnancy" (43.6%). Ill-defined causes ranked second according to the LBE-OF (35.4%) and third according to LBE < 5. Some 30% of stillbirths changed groups and subgroups of avoidability, showing greater consistency with the profile of obstetric care. Although identifying a higher percentage of ill-defined causes, the LBE-OF is more consistent with the pathophysiology of fetal deaths. The inclusion of stillbirths in the SIM would be a positive step in monitoring and upgrading the investigation of causes of fetal death.

Revisamos as categorias da 10ª revisão da Classificação Internacional de Doenças (CID-10) presentes na LBE < 5 e as realocamos nos grupos de evitabilidade, segundo momento do óbito em relação ao parto e as causas condizentes com óbitos fetais. Condições que não esclarecem os determinantes do óbito foram alocadas como causas mal definidas. Óbitos fetais no Estado do Rio de Janeiro - selecionados das bases do Sistema de Informações sobre Mortalidade (SIM) - foram classificados segundo LBE-OF e a LBE < 5. Ao classificar os 2.585 óbitos fetais do Estado do Rio de Janeiro ocorridos em 2018, observou-se que, segundo a LBE < 5, predominariam causas "reduzíveis por adequada atenção ao parto" (42,9%), já pela LBE-OF, aquelas "reduzíveis por adequada atenção à mulher na gestação" foram as mais frequentes (43,6%). As causas mal definidas ocuparam a segunda posição segundo a LBE-OF (35,4%) e a terceira posição segundo LBE < 5. Cerca de 30% dos óbitos fetais mudaram de grupos e subgrupos de evitabilidade, mostrando maior coerência com o perfil de atenção obstétrica. Embora identificando um maior percentual de causas mal definidas, a LBE-OF coaduna-se mais com a fisiopatologia dos óbitos fetais. Sua inserção no SIM avançaria no sentido de monitorar e qualificar a investigação de causas de morte fetal.

Effects of anodal multichannel transcranial direct current stimulation (tDCS) on social-cognitive performance in healthy subjects: A randomized sham-controlled crossover pilot study.

Recent studies suggest that temporoparietal junction (TPJ) modulation can influence attention and social cognition performance. Nevertheless, no studies have used multichannel transcranial direct current stimulation (tDCS) over bilateral TPJ to estimate the effects on these neuropsychological functions. The project STIPED is using optimized multichannel stimulation as an innovative treatment approach for chronic pediatric neurodevelopmental disorders, namely in children/adolescents with Autism Spectrum Disorder (ASD). In this pilot study, we aim to explore whether anodal multichannel tDCS coupled with a Joint Attention Task (JAT) influences social-cognitive task performance relative to sham stimulation, both in an Emotion Recognition Task (ERT) and in a Mooney Faces Detection Task (MFDT), as well as to evaluate this technique's safety and tolerability. Twenty healthy adults were enrolled in a randomized, single-blinded, sham-controlled, crossover study. During two sessions, participants completed the ERT and the MFDT before and after 20min of sham or anodal tDCS over bilateral TPJ. No significant differences on performance accuracy and reaction time were found between stimulation conditions for all tasks, including the JAT. A significant main time effect for overall accuracy and reaction time was found for the MFDT. Itching was the most common side effect and stimulation conditions detection was at chance level. Results suggest that multichannel tDCS over bilateral TPJ does not affect performance of low-level emotional recognition tasks in healthy adults. Although preliminary safety and tolerability are demonstrated, further studies over longer periods will be pursued to investigate the clinical efficacy in children/adolescents with ASD, where social cognition impairments are preponderant.

Human epidermal growth factor receptor 2 fluorescence in situ hybridization and P57KIP2 immunohistochemistry using tissue microarray: Improving histopathological subtyping of hydatidiform mole.

INTRODUCTION: Trophoblastic neoplasia is detected in approximately 25% of complete hydatidiform moles (CMs) and 0.5% of partial hydatidiform moles (PMs). Hydatidiform mole (HM) subtyping is important to properly monitor and predict patient outcomes. Ploidy studies generally involve diploid CMs and triploid PMs. P57KIP2, expressed in the maternal genome, is usually not detected in CM. We determined whether HER2 FISH and p57 immunostaining contributed to the histopathological classification of HMs. METHODS: This retrospective cohort study focused on patients diagnosed with HM by histopathological examination who were followed up at a trophoblastic disease center from 2002 to 2017. Pathological samples of 108 products of conception were reviewed and reclassified according to detailed criteria. Tissue microarray technology (TMA) was used for p57 KIP2 immunostaining and HER2 FISH analysis. RESULTS: Histopathological review showed 57 (53%) CMs, 47 (43%) PMs and 4 (4%) inconclusive cases. P57 immunostaining revealed 59 (55%) negative and 22 (20%) positive specimens, and 27 (25%) were inadequate for analysis. FISH HER2 detected 68 (63%) diploid and 33 (30%) triploid cases; two (2%) had oncogene amplification. The three strategies led to a diagnostic change in 28 samples (26%). The final diagnosis was CM in 75 cases (70%) and PM in 30 (28%); three cases remained inconclusive. DISCUSSION: TMA is a cost-saving method that allows the simultaneous study of large case series. The combination of histopathology, HER2 FISH and p57 tests can be useful for accurately differentiating CM and PM, thus providing additional information on disease prognosis.

Should arboviruses be the only diagnosis hypothesis in pregnant women in endemic areas presenting with a rash?

Listeria is an unusual pathogen that causes neonatal infection with high morbidity and mortality. We present the case of a premature newborn whose mother had a rash during pregnancy; the newborn had severe early sepsis because of Listeria monocytogenes and histopathologically suggestive findings of the placenta. Obstetricians and neonatologists should suspect listeriosis in cases with compatible epidemiological history, clinical features, and examination findings of the placenta.

Gestational Trophoblastic Neoplasia after Ectopic Molar Pregnancy: Clinical, Diagnostic, and Therapeutic Aspects.

This report presents the case of a patient with gestational trophoblastic neoplasia after a partial hydatidiform mole formed in the Fallopian tube. Ectopic molar pregnancy is a rare condition, with an estimated incidence of 1 in every 20,000 to 100,000 pregnancies; less than 300 cases of it have been reported in the Western literature. The present report is important because it presents current diagnostic criteria for this rare condition, which has been incorrectly diagnosed in the past, not only morphologically but also immunohistochemically. It also draws the attention of obstetricians to the occurrence of ectopic molar pregnancy, which tends to progress to Fallopian tube rupture more often than in cases of ectopic non-molar pregnancy. Progression to gestational trophoblastic neoplasia ensures that patients with ectopic molar pregnancy must undergo postmolar monitoring, which must be just as thorough as that of patients with intrauterine hydatidiform moles, even if chemotherapy results in high cure rates.

Esse relato apresenta um caso de neoplasia trofoblástica gestacional após mola hidatiforme parcial ocorrida na tuba uterina. Trata-se de uma associação rara, cuja incidência estima-se de 1 em cada 20.000 a 100.000 gestações, havendo menos de 300 casos apresentados na literatura ocidental. O tema é importante porque apresenta critérios diagnósticos atuais para essa ocorrência incomum, que vinha sendo diagnosticada equivocadamente, não apenas sob o ponto de vista morfológico, como também imunohistoquímico. Da mesma forma, alerta o obstetra para a ocorrência da gravidez molar ectópica, que tende a evoluir com rotura tubária mais frequentemente do que os casos de gravidez ectópica não molar. Por fim, a evolução do caso para neoplasia trofoblástica gestacional impõe às pacientes com gravidez ectópica molar a necessidade de seguimento pós-molar tão rigoroso quanto nos casos de mola hidatiforme intrauterina, ainda que o tratamento quimioterápico determine elevadas taxas de cura.

The spectrum of neuropathological changes associated with congenital Zika virus infection.

A major concern associated with ZIKV infection is the increased incidence of microcephaly with frequent calcifications in infants born from infected mothers. To date, postmortem analysis of the central nervous system (CNS) in congenital infection is limited to individual reports or small series. We report a comprehensive neuropathological study in ten newborn babies infected with ZIKV during pregnancy, including the spinal cords and dorsal root ganglia (DRG), and also muscle, pituitaries, eye, systemic organs, and placentas. Using in situ hybridization (ISH) and electron microscopy, we investigated the role of direct viral infection in the pathogenesis of the lesions. Nine women had Zika symptoms between the 4th and 18th and one in the 28th gestational week. Two babies were born at 32, one at 34 and 36 weeks each and six at term. The cephalic perimeter was reduced in four, and normal or enlarged in six patients, although the brain weights were lower than expected. All had arthrogryposis, except the patient infected at 28 weeks gestation. We defined three patterns of CNS lesions, with different patterns of destructive, calcification, hypoplasia, and migration disturbances. Ventriculomegaly was severe in the first pattern due to midbrain damage with aqueduct stenosis/distortion. The second pattern had small brains and mild/moderate (ex-vacuo) ventriculomegaly. The third pattern, a well-formed brain with mild calcification, coincided with late infection. The absence of descending fibres resulted in hypoplastic basis pontis, pyramids, and cortico-spinal tracts. Spinal motor cell loss explained the intrauterine akinesia, arthrogryposis, and neurogenic muscle atrophy. DRG, dorsal nerve roots, and columns were normal. Lympho-histiocytic inflammation was mild. ISH showed meningeal, germinal matrix, and neocortical infection, consistent with neural progenitors death leading to proliferation and migration disorders. A secondary ischemic process may explain the destructive lesions. In conclusion, we characterized the destructive and malformative consequences of ZIKV in the nervous system, as reflected in the topography and severity of lesions, anatomic localization of the virus, and timing of infection during gestation. Our findings indicate a developmental vulnerability of the immature CNS, and shed light on possible mechanisms of brain injury of this newly recognized public health threat.

Dengue infection in pregnancy and its impact on the placenta.

A histopathological and immunohistochemical study was conducted in placental tissues and retained products of conception from 24 patients with confirmed dengue infection during pregnancy. The immunohistochemical assay was positive for dengue virus in 19 placental and three ovular remnants analyzed. The light microscopic findings were signs of hypoxia, choriodeciduitis, deciduitis and intervillositis and the viral antigens were found in cytoplasmic of the trophoblast, villous stroma and decidua. Our results suggest that immunohistochemistry could be used as a laboratory confirmation method for dengue in pregnant women, especially in endemic areas when embedded material is the only material available.

Biofilm formation in catheter-related infections by Panton-Valentine leukocidin-producing Staphylococcus aureus

The use of invasive techniques, such as intravascular catheter insertion, and the formation of biofilms in several devices by methicillin-resistant Staphylococcus aureus (MRSA) have contributed to the increased number of septic patients, morbidity and mortality. This study aimed to evaluate the virulence of strains through catheter colonization and identification of microbial biofilm, as well as pathological changes on the colonized skin. An experimental biofilm formation model utilized catheter fragments implanted subcutaneously in 25 Swiss mice. The technique consisted of inoculating a catheter fragment on the back of each animal, followed by intradermal inoculation of 50 µl of bacterial suspension at 1.0 × 107 colony forming units/ml. After 96 h, catheters were removed for macroscopic analysis and evaluated through culture. Local skin fragments were also extracted for histopathology analysis. Staphylococcus aureus can adhere to catheters, colonize and form biofilms. The high amount of viable bacterial cells colonizing catheters and virulence factors can lead to severe infections of skin and adjacent tissues (AU)

Breast cancer and neurofibromatosis type 1: a diagnostic challenge in patients with a high number of neurofibromas.

BACKGROUND: Neurofibromatosis 1 is one of the most common genetic diseases in humans, presenting with multiple neurofibromas and an increased risk of various benign and malignant tumors, including breast cancer. CASE PRESENTATION: In this paper we report a case of a woman with neurofibromatosis 1 and the challenge associated with detecting an advanced breast cancer because of numerous skin neurofibromas, which were responsible for a substantial delay in cancer diagnosis. Literature concerning the association of neurofibromatosis 1 and breast cancer is reviewed and discussed. CONCLUSIONS: Best practice guidelines for breast cancer detection are not sufficient for the screening of neurofibromatosis 1 carriers. A more intensive clinical and imaging approach should be used if the same early detection rate as in non-neurofibromatosis 1 women is to be achieved.

El área de conocimiento más destacada fue el de las ciencias de la salud (60,8%). El tiempo promedio entre la presentación y la evaluación ética fue de 11 días. El área de conocimiento influyó en el tiempo pasado entre la presentación y la valoración ética (p < 0,05), pero no en la aprobación del proyecto. Se concluyó que el comité local sigue las normas para la consideración ética para cumplir con la Resolución 466/2012, una vez que reprobó proyectos con fallas en el Término de Consentimiento Informado, protegiendo a los sujetos.
