A systematic review and meta-analysis of how social memory is studied.

Social recognition is crucial for survival in social species, and necessary for group living, selective reproduction, pair bonding, and dominance hierarchies. Mice and rats are the most commonly used animal models in social memory research, however current paradigms do not account for the complex social dynamics they exhibit in the wild. To assess the range of social memories being studied, we conducted a systematic analysis of neuroscience articles testing the social memory of mice and rats published within the past two decades and analyzed their methods. Our results show that despite these rodent's rich social memory capabilities, the majority of social recognition papers explore short-term memories and short-term familiarity levels with minimal exposure between subject and familiar stimuli-a narrow type of social memory. We have identified several key areas currently understudied or underrepresented: kin relationships, mates, social ranks, sex variabilities, and the effects of aging. Additionally, reporting on social stimulus variables such as housing history, strain, and age, is limited, which may impede reproducibility. Overall, our data highlight large gaps in the diversity of social memories studied and the effects social variables have on social memory mechanisms.

Enfermedad renal crónica asociada a la exposición a metales pesados y productos agroquímicos en Latinoamérica / Chronic kidney disease associated with heavy metal exposure and agrochemicals in Latin America

Introducción: La Organización Panamericana de la Salud reco-noce a la Enfermedad Renal Crónica de Causas No Tradiciona-les como una forma grave de insuficiencia renal de etiología incierta, la cual ha alcanzado proporciones epidémicas en las comunidades y saturación de los sistemas de salud. La enfer-medad se ha relacionado con infecciones, deshidratación, hi-peruricemia, exposición a agroquímicos o metales pesados y susceptibilidad genética. Objetivo: Realizar una revisión integradora sobre la relación entre la enfermedad renal de causa no tradicional con factores sociodemográficos, exposición agrícola y metales pesados en población latinoamericana. Metodología: Se realizó una revisión sistemática integradora bajo la guía PRISMA en las bases de datos Medigraphic, Bio-Med Central, Wiley Online Library, Web of Science, Science-Direct, PubMed y Scopus. Con las palabras claves: enfermedad renal, nefritis, metales pesados, agroquímicos, factor de riesgo. Se incluyeron 39 estudios después de evaluar la calidad meto-dológica de los mismos. Resultados: El 35,89% de los estudios incluídos tuvo una rigu-rosidad científica alta. Referente a las causas, se encontró que la exposición a agroquímicos fue la causa de mayor frecuencia en el padecimiento de esta enfermedad. Conclusión: Los metales pesados y agroquímicos han demos-trado influir en el desarrollo de la Enfermedad Renal Crónica de causas no tradicionales, no obstante, la mayoría de los re-sultados de los artículos incluidos no tienen resultados genera-lizables ni estadísticamente significativos. Los factores socio-demográficos han sido poco estudiados y se requiere de mayor investigación con rigurosidad científica sobre esta variable.(AU)

ntroduction: The Pan American Health Organization recognizes Chronic Kidney Disease of Nontraditional Causes as a serious form of kidney failure of uncertain etiology, which has reached devastating epidemic proportions in communities and saturation of health systems. Hypotheses related to infections, dehydration, global warming, hyperuricemia, exposure to agrochemicals or heavy metals and genetic susceptibility are mentioned, however, these hypotheses have not been conclusive. Objective: To carry out a systematic review on the relationship between non-traditional kidney disease and sociodemographic factors, agricultural exposure or heavy metals in the Latin American population. Methodology: An integrative systematic review was carried out under the PRISMA guide in the Medigraphic, BioMed Central, Wiley Online Library, Web of Science, ScienceDirect, PubMed and Scopus databases. With the keywords: kidney disease, nephritis, heavy metals, agrochemicals, risk factor. Of which 39 studies were included after evaluating their methodological quality. Results: it was found that 35.89% of the included studies had a high scientific rigor. Regarding the causes, it was found that exposure to agrochemicals was the most frequent cause of this disease. Conclusion: Heavy metals and agrochemicals have been shown to influence the development of Chronic Kidney Disease of Nontraditional Causes, however, most of the results are not generals and doesn ́t demonstrate a statistically significant relationship. Sociodemographic factors have been little studied and more rigorous scientific research on this variable is required.(AU)

Deltoid muscle strength and autonomic dysfunction as independent risk factors for invasive mechanical ventilation in patients with Guillain-Barré syndrome.

BACKGROUND: Almost a third of patients with Guillain-Barré Syndrome (GBS) require mechanical ventilation, increasing mortality by 15-30% and proving poor functional outcomes. The Erasmus GBS Respiratory Insufficiency Score (EGRIS) is the most frequently used scale to assess probability of respiratory insufficiency within the first week of admission. We aim to determine other clinical and electrophysiological prognostic factors for invasive mechanical ventilation (IMV) in patients with GBS. MATERIAL AND METHODS: A cross-sectional ambispective cohort study was carried out in a referral center in Mexico City, from January 2015 to December 2019. Baseline demographics, MRC score, Hughes scale, EGRIS, dysautonomia and nerve conduction studies were performed on admission in GBS patients that required IMV. A multivariable analysis for IMV and a survival analysis for independent walk in prolonged-IMV (>14 days) were performed. RESULTS: Forty-nine (32%) out of 153 GBS patients required IMV. Statistically significant prognostic factors in multivariable analysis were deltoid muscle strength ≤2 [OR 7.1 (1.6-31.1)], EGRIS [OR 2.5 (1.3-4.6)] and autonomic dysfunction [OR 6.6 (2.0-22.0)]. Electrodecrement <1 mV in the compound muscle action potential (CMAP) of distal motor median nerve was more prevalent in prolonged-IMV patients (44.8% vs. 21%, p = .049). A significant minor prevalence of prolonged-IMV patients regain independent walk at 6 months using the Kaplan-Meier method (log rank test p < .001). CONCLUSIONS: We provide new specific clinical (deltoid muscle strength and autonomic dysfunction) and electrophysiological variables to discriminate GBS patients that will require IMV.

Parental attitudes in the pediatric emergency department about the COVID-19 vaccine.

BACKGROUND: COVID-19 vaccinations are now recommended in the United States (U.S.) for children ≥ 6 months old. However, pediatric vaccination rates remain low, particularly in the Hispanic/Latinx population. OBJECTIVE: Using the 4C vaccine hesitancy framework (calculation, complacency, confidence, convenience), we examined parental attitudes in the emergency department (ED) towards COVID-19 vaccination, identified dimensions of parental vaccine hesitancy, and assessed parental willingness to have their child receive the COVID-19 vaccine. METHODS: As part of a larger multi-methods study examining influenza vaccine hesitancy, we conducted interviews that included questions about COVID-19 vaccine authorization for children. We used directed content analysis to extract qualitative themes from 3 groups of parents in the ED: Hispanic/Latinx Spanish speaking (HS), Hispanic/Latinx English speaking (HE), non-Hispanic/non-Latinx White English speaking (WE). Themes were triangulated with the Parent Attitudes about Childhood Vaccines (PACV) survey, where higher scores indicate increased vaccine hesitancy. RESULTS: Factors influencing vaccine hesitancy were mapped to the 4C framework from 58 sets of interviews and PACVs. HE and HS parents, compared to WE parents, had less knowledge about COVID-19 and its vaccine, and more beliefs in COVID-19 vaccine myths. However, both HS and HE parent groups were more inclined to endorse COVID-19 vaccine effectiveness as a reason to have their children vaccinated. HS parents felt that COVID-19 increased their fear of illnesses in general and were worried about confusing COVID-19 with other infections. Median PACV scores of HS (Mdn = 20) and HE (Mdn = 20) parent groups were higher than of WE parents (Mdn = 10), but parental willingness to have their child receive COVID-19 vaccination was similar across groups. CONCLUSIONS: Higher COVID-19 vaccine hesitancy among HS and HE parents compared to WE parents may be attributed to insufficient knowledge about COVID-19, its vaccine, along with COVID-19 vaccine myths. Efforts to provide targeted vaccine education to different populations is warranted.

Resting State Psychophysiology in Youth with OCD and Their Caregivers: Preliminary Evidence for Trend Synchrony and Links to Family Functioning.

The burden of OCD in children and adolescents extends to their caregivers. Prior work in other disorders and unaffected youth has found synchrony in psychophysiological arousal for youth-caregiver dyads. This preliminary study explored whether psychophysiological trend synchrony in youth-caregiver dyads (N = 48) occurred and was moderated by youth OCD diagnosis. We also explored whether psychophysiological indices (i.e., electrodermal activity, heart rate, respiratory sinus arrhythmia) were correlated with reported family functioning in the OCD subsample (n = 25). Youth with OCD had higher resting heart rate than unaffected peers; this was not replicated in caregivers. Trend synchrony was found across the full sample of dyads for electrodermal activity and heart rate, with no moderation by diagnostic group. In the OCD group, youth heart rate was correlated with family conflict and caregiver heart rate with expressiveness. Findings provide preliminary support for further examination of heart rate and family factors in OCD-affected youth and their caregivers.

Haemosporidians from a Neglected Group of Terrestrial Wild Birds in the Peruvian Amazonia.

Haemosporidians are a widespread group of blood parasites transmitted by vectors. Despite their relevance for bird conservation, few studies have been conducted in the Amazonia and even less in terrestrial wild birds. We analysed blood samples from 168 game birds, collected from 2008 to 2015 by subsistence hunters of an indigenous rural community in the Peruvian Amazonia. DNA was tested for Haemoproteus spp., Plasmodium spp. and Leucocytozoon spp. and positive amplicons were sequenced and curated for phylogenetic analysis. Haemosporidian prevalence was 72% overall, 66.7% for Haemoproteus spp. and 5.4% for Plasmodium spp. and respectively by bird species: Spix's Guan (Penelope jacquacu, n = 72) 87.5% and 0%, Razor-billed Curassow (Mitu tuberosum, n = 45) 77.8% and 6.7%, White-winged Trumpeter (Psophia leucoptera, n = 20) 6.3% and 12.5%, Blue-throated Piping-guan (Pipile cumanensis, n = 16) 73.3% and 6.7%, and Great Tinamou (Tinamus major, n = 15) 10% and 15%. Leucocytozoon spp. was not found. P. leucoptera and T. major were less likely to be infected with Haemoproteus spp. Fruit abundance had a negative association with Haemoproteus spp. prevalence and precipitation was negatively associated with Plasmodium spp. prevalence. The 106 sequences examined represented 29 lineages, 82.8% of them were new lineages (Plasmodium n = 3, Haemoproteus n = 21). Novel host-parasite associations and lineages were unveiled, including probably new species of Plasmodium spp. Our results highlight the scientific value of alternative sampling methods and the collaboration with local communities.

NMR-based metabolomics of human cerebrospinal fluid identifies signature of brain death.

INTRODUCTION: Brain death (BD) is the irreversible cessation of all functions of the entire brain, including the brainstem. Cerebrospinal fluid (CSF) is a biological liquid that circulates in brain and spine. Metabolomics is able to reveal the response of biological systems to diverse factors in a specific moment or condition. Therefore, the study of this neurological condition through metabolic profiling using high resolution Nuclear Magnetic Resonance (NMR) spectroscopy is important for understanding biochemical events. OBJECTIVES: The aim of the current study is to identify the metabolomics signature of BD using 1H-NMR spectroscopy in human CSF. METHODS: 1H-NMR spectroscopy has been employed for metabolomic untargeted analysis in 46 CSF samples: 22 control and 24 with BD. Spectral data were further subjected to multivariate analysis. RESULTS: Statistically significant multivariate models separated subject's samples with BD from controls and revealed twenty one discriminatory metabolites. The statistical analysis of control and BD subjects using Orthogonal Projections to Latent Structures Discriminant Analysis (OPLS-DA) model resulted in R2X of 0.733 and Q2 of 0.635. An elevation in the concentration of statistically discriminant metabolites in BD was observed. CONCLUSION: This study identifies a metabolic signature associated with BD and the most relevant enriched selected metabolic pathways.

Shared and unique neural mechanisms underlying pediatric trichotillomania and obsessive compulsive disorder.

BACKGROUND: Little is known about the neural underpinnings of pediatric trichotillomania (TTM). We examined error-related negativity (ERN)-amplitude and theta-EEG power differences among youth with TTM, OCD, and healthy controls (HC). METHODS: Forty channel EEG was recorded from 63 pediatric participants (22 with TTM, 22 with OCD, and 19 HC) during the Eriksen Flanker Task. EEG data from inhibitory control were used to derive estimates of ERN amplitude and event-related spectral power associated with motor inhibition. RESULTS: TTM and HC were similar in brain activity patterns in frontal and central regions and TTM and OCD were similar in the parietal region. Frontal ERN-amplitude was significantly larger in OCD relative to TTM and HC, who did not differ from each other. The TTM group had higher theta power compared to OCD in frontal and central regions, and higher theta than both comparison groups in right motor cortex and superior parietal regions. Within TTM, flanker task performance was correlated with EEG activity in frontal, central, and motor cortices whereas global functioning and impairment were associated with EEG power in bilateral motor and parietal cortices. CONCLUSIONS: Findings are discussed in terms of shared and unique neural mechanisms in TTM and OCD and treatment implications.

Words Matter: What Do Patients Find Judgmental or Offensive in Outpatient Notes?

BACKGROUND: Sharing outpatient notes with patients may bring clinically important benefits, but notes may sometimes cause patients to feel judged or offended, and thereby reduce trust. OBJECTIVE: As part of a larger survey examining the effects of open notes, we sought to understand how many patients feel judged or offended due to something they read in outpatient notes, and why. DESIGN: We analyzed responses from a large Internet survey of adult patients who used secure patient portals and had at least 1 visit note available in a 12-month period at 2 large academic medical systems in Boston and Seattle, and in a rural integrated health system in Pennsylvania. PARTICIPANTS: Adult ambulatory patients with portal accounts in health systems that offered open notes for up to 7 years. APPROACH: (1) Quantitative analysis of 2 dichotomous questions, and (2) qualitative thematic analysis of free-text responses on what patients found judgmental or offensive. KEY RESULTS: Among 22,959 patient respondents who had read at least one note and answered the 2 questions, 2,411 (10.5%) reported feeling judged and/or offended by something they read in their note(s). Patients who reported poor health, unemployment, or inability to work were more likely to feel judged or offended. Among the 2,411 patients who felt judged and/or offended, 2,137 (84.5%) wrote about what prompted their feelings. Three thematic domains emerged: (1) errors and surprises, (2) labeling, and (3) disrespect. CONCLUSIONS: One in 10 respondents reported feeling judged/offended by something they read in an outpatient note due to the perception that it contained errors, surprises, labeling, or evidence of disrespect. The content and tone may be particularly important to patients in poor health. Enhanced clinician awareness of the patient perspective may promote an improved medical lexicon, reduce the transmission of bias to other clinicians, and reinforce healing relationships.

Diversity, distribution and natural Leishmania infection of sand flies from communities along the Interoceanic Highway in the Southeastern Peruvian Amazon.

The Peruvian-Brazilian border is a highly endemic tegumentary leishmaniasis region in South America. The interoceanic highway is a commercial route that connects Peru and Brazil through Madre de Dios and has raised concerns about its impact on previously undisturbed areas. In order to assess leishmaniasis transmission risk along this highway, we conducted a surveillance study of the sand fly populations in this area. Sand flies were collected between 2009 and 2010 along transects at 200 m, 600 m and 1000 m from six study sites located along the highway (Iberia, La Novia, Alto Libertad, El Carmen, Florida Baja, Mazuko and Mavila) and an undisturbed area (Malinowski). Collected specimens were identified based on morphology and non-engorged females of each species were pooled and screened by kinetoplast PCR to detect natural Leishmania infections. A total of 9,023 specimens were collected belonging to 54 different Lutzomyia species including the first report of Lu. gantieri in Peru. Four species accounted for 50% of all specimens (Lutzomyia carrerai carrerai, Lu. davisi, Lu. shawi and Lu. richardwardi). El Carmen, Alto Libertad, Florida Baja and Malinowski presented higher Shannon diversity indexes (H = 2.36, 2.30, 2.17 and 2.13, respectively) than the most human disturbed sites of Mazuko and La Novia (H = 1.53 and 1.06, respectively). PCR detected 10 positive pools belonging to Lu. carrerai carrerai, Lu. yuilli yuilli, Lu. hirsuta hirsuta, Lu. (Trichophoromyia) spp., and Lu. (Lutzomyia) spp. Positive pools from 1,000 m transects had higher infectivity rates than those from 600 m and 200 m transects (9/169 = 5.3% vs 0/79 = 0% and 1/127 = 0.8%, p = 0.018). El Carmen, accounted for eight out of ten positives whereas one positive was collected in Florida Baja and Mazuko each. Our study has shown differences in sand fly diversity, abundance and species composition across and within sites. Multiple clustered Lutzomyia pools with natural Leishmania infection suggest a complex, diverse and spotty role in leishmaniasis transmission in Madre de Dios, with increased risk farther from the highway.

Ethnicity moderates outcome in family focused treatment for pediatric obsessive compulsive disorder.

OBJECTIVE: This study examined predictors and moderators of treatment outcome in a randomized controlled trial (RCT) comparing two active interventions for pediatric obsessive compulsive disorder that differed with respect to the focus and format of family intervention. We had a particular interest in the role of race/ethnicity in shaping outcomes given our relatively diverse sample composition and the limited prior work in this area. METHOD: A total of 62 youths (Mean age = 12.71 years; 57 % male; 34 % non-white) were assigned to either a standard cognitive behavioral therapy (CBT) family intervention (ST) or to a tailored intervention designed for cases of OCD complicated by poor family functioning (Enhanced Family Therapy; ET). Treatment in both arms involved 12 sessions of exposure therapy; the family interventions differed. Predictor and moderator variables were chosen based on the extant literature. RESULTS: Minority status did not predict outcome, suggesting that overall, white and non-white youth had comparable treatment response. Race/ethnicity did, however, moderate response with non-white youth faring better in the ET arm of the study. In particular, minority youth in ET had, on average, post-treatment CYBOCS scores consistent with clinical remission whereas their ST counterparts were left with symptoms considered moderately severe. There were no predictors of treatment outcome. CONCLUSIONS: Minority status predicts poorer response to standard CBT across disorders, suggesting the need for possible treatment adaptations. The present findings highlight one avenue for matching patients to treatments that might optimize outcomes and underscore the value of family involvement in OCD treatment.

The Impact of Treatment Expectations on Exposure Process and Treatment Outcome in Childhood Anxiety Disorders.

This study examined the relationship between caregivers' and youths' treatment expectations and characteristics of exposure tasks (quantity, mastery, compliance) in cognitive-behavioral therapy (CBT) for childhood anxiety. Additionally, compliance with exposure tasks was tested as a mediator of the relationship between treatment expectations and symptom improvement. Data were from youth (N = 279; 7-17 years old) enrolled in the Child/Adolescent Anxiety Multimodal Study (CAMS) and randomized to cognitive-behavioral therapy (CBT) or the combination of CBT and sertraline for the treatment of separation anxiety disorder, generalized anxiety disorder, and social phobia. Caregivers and youth independently reported treatment expectations prior to randomization, anxiety was assessed pre- and post-treatment by independent evaluators blind to treatment condition, and exposure characteristics were recorded by the cognitive-behavioral therapists following each session. For both caregivers and youths, more positive expectations that anxiety would improve with treatment were associated with greater compliance with exposure tasks, and compliance mediated the relationship between treatment expectations and change in anxiety symptoms following treatment. Additionally, more positive parent treatment expectations were related to a greater number and percentage of sessions with exposure. More positive youth treatment expectations were associated with greater mastery during sessions focused on exposure. Findings underscore the importance of addressing parents' and youths' treatment expectations at the outset of therapy to facilitate engagement in exposure and maximize therapeutic gains.

Trombosis venosa cerebral en la Unidad de Cuidados Intensivos Neurológicos del Instituto Nacional de Neurología y Neurocirugía / Brain venous thrombosis in the unit of neurological intensive care of the National Institute of Neurology and Neurosurgery / Trombose venosa cerebral na Unidade de Terapia Intensiva Neurológica do Instituto Nacional de Neurologia e Neurocirurgia

Abstract: Cerebral venous thrombosis (TVC) is a potentially devastating state that occurs in young adults, especially women. Less frequent subtype of cerebral vascular disease (EVC), represented only 0.5% in EVC patients. Headache is the most common symptom common. It requires an accurate diagnosis since the pathophysiology and treatment differ from the arterial EVC. The understanding of the risk factors is the key to the prognosis of the TVC. Objective: To determine the prevalence, the main clinical, radiological findings and prognosis of TVC in Neurological Intensive Care Unit. Material and methods: Retrospective, longitudinal and analytical study of an observational nature. All patients admitted to the Neurological Intensive Care Unit of the National Institute of Neurology and Neurosurgery (INNN) with the diagnosis of TVC from January 2010 to July 2019 confirmed by venous phase computed tomography (vein CT) and/or vein were considered MRI (vein MRI), which will have clinical information and cabinet studies, as well as, the evolution, treatment and prognosis at hospital discharge. Results: Of a total of 14 patients, with an average age of 33 years of age. Of which 85.72% (n = 12) were women and 14.28 (n = 2) were men. Headache occurred 50% of cases. The main predisposing cause for TVC was the use of oral contraceptives in 6 patients (42.85%) and puerperium in three patients (21.42%). The delay in diagnosis was an average of 48 hours. The imaging method used for diagnosis in 64.28% of those with computed tomography in venous phase and in 37.71% with vein magnetic resonance. The upper longitudinal sinus was the most affected in 50% of cases. The average stay in the Intensive Care Unit (ICU) was seven days, where 100% of patients received anticoagulation. Three patients (21.4%) developed intracranial hypertension who underwent decompressive craniectomy between the second and fifth day of stay. The days of mechanical ventilation on average were seven days. With an average hospital stay of 20 days. Mortality at hospital discharge was 21.42%. Conclusions: TVC is less frequent than ischemic stroke or intracerebral hemorrhage. The spectrum of the clinic is broad, with pivotal headache. The confirmation of the diagnosis must be performed with CT vein and/or RM vein. The therapeutic intervention within the acute phase is aimed at the recanalization of the thrombosed sinus or sinuses and the prevention of complications; anticoagulation with low molecular weight heparin is the first-line treatment, which has shown an impact on the prognosis of patients. We must keep in mind that thrombolysis and thrombectomy are an option in treatment. In the case of decompressive craniectomy, it is indicated only in cases of malignant venous infarctions. The results after TVC are generally favorable, they also depend on the patient's factors, such as sex and the specific risk factors of women.

Resumo: Trombose venosa cerebral (TVC) é um estado potencialmente devastador que ocorre em adultos jovens, especialmente mulheres. Subtipo menos frequente do acidente vascular cerebral (AVC), representou apenas 0.5% nos pacientes com AVC. Cefaléia é o sintoma mais comum. Exige um diagnóstico preciso, pois a fisiopatologia e o tratamento diferem da AVC arterial, e a compreensão dos fatores de risco é a chave para o prognóstico da TVC. Objetivo: Determinar a prevalência, os principais achados clínicos, radiológicos e prognósticos da TVC na unidade de terapia intensiva neurológica. Material e métodos: Estudo retrospectivo, longitudinal e analítico de natureza observacional. Todos os pacientes admitidos na unidade de terapia intensiva neurológica do Instituto Nacional de Neurologia e Neurocirurgia (INNN) com diagnóstico de TVC de janeiro de 2010 a julho de 2019 confirmados por tomografia computadorizada de fase venosa (Veno-TC) e/ou veno ressonância magnética (veno-RM), que contaram com informações clínicas e estudos de gabinete, bem como a evolução, tratamento e prognóstico na alta hospitalar. Resultados: Do total de 14 pacientes, com idade média de 33 anos. Dos quais 85.72% (n = 12) eram mulheres e 14.28 (n = 2) eram homens. A cefaléia ocorreu em 50% dos casos. A principal causa predisponente para TVC foi o uso de contraceptivos orais em 6 pacientes (42.85%) e puerpério em 3 pacientes (21.42%). O atraso no diagnóstico foi em média de 48 horas. O método de imagem utilizado para o diagnóstico em 64.28% daqueles com tomografia computadorizada na fase venosa e em 37.71% com veno ressonância magnética. O seio sagital superior foi o mais acometido em 50% dos casos. A permanência média na unidade de terapia intensiva (UTI) foi de 7 dias, onde 100% dos pacientes receberam anticoagulação. Três pacientes (21.4%) desenvolveram hipertensão intracraniana submetidos a craniectomia descompressiva entre o segundo e o quinto dia de internação. Os dias de ventilação mecânica foram em média 7 dias. Com internação média de 20 dias. A mortalidade na alta hospitalar foi de 21.42%. Conclusões: A TVC é menos frequente que o AVC isquêmico ou hemorragia intracerebral. O espectro da clínica é amplo, tendo como sintoma principal cefaléia. A confirmação do diagnóstico deve ser realizada com veno TC e/ou veno RM. A intervenção terapêutica na fase aguda visa à recanalização do seio ou seios trombosados e à prevenção de complicações; a anticoagulação com heparina de baixo peso molecular é o tratamento de primeira linha que demonstrou um impacto no prognóstico dos pacientes. Devemos ter em mente que trombólise e trombectomia são uma opção no tratamento. No caso da craniectomia descompressiva, é indicado apenas em casos de infartos venosos malignos. Os resultados após o TVC são geralmente favoráveis, também dependem de fatores do paciente, como sexo e fatores de risco específicos da mulher.

Serologic Evidence of Zoonotic Alphaviruses in Humans from an Indigenous Community in the Peruvian Amazon.

Alphaviruses (Togaviridae, Alphavirus) are arthropod-borne single-stranded RNA pathogens that cause febrile and neurologic disease in much of Latin America. However, many features of Alphavirus epidemiology remain unknown. In 2011, we undertook a cross-sectional study in Nueva Esperanza, an indigenous community in the Peruvian Amazon. Here, we present the first serologic evidence of Mayaro (MAYV), Venezuelan equine encephalitis (VEE) complex alphavirus, Una (UNAV), and Madariaga (MADV) viruses reported in humans (24%, 16%, 13%, and 1.5%, respectively) from an Amazonian indigenous community in Peru. Hunting activity and cohabiting with hunters were the main risk factors for Mayaro seroconversion, but only hunting was associated with UNAV seropositivity. Our results suggest that alphavirus infection in this region is common, but we highlight the high UNAV seroprevalence found and corroborate the low MADV prevalence reported in this region. Furthermore, MAYV-neutralizing antibodies were also detected in stored samples from wild animals (18%) hunted by Nueva Esperanza inhabitants and another mestizo community located close to Iquitos. Further serological surveys of VEE complex alphaviruses, UNAV, and MADV in wild animals and assessing the ability of the MAYV seropositive species to transmit the virus will be relevant.

OpenNotes After 7 Years: Patient Experiences With Ongoing Access to Their Clinicians' Outpatient Visit Notes.

BACKGROUND: Following a 2010-2011 pilot intervention in which a limited sample of primary care doctors offered their patients secure Web-based portal access to their office visit notes, the participating sites expanded OpenNotes to nearly all clinicians in primary care, medical, and surgical specialty practices. OBJECTIVE: The aim of this study was to examine the ongoing experiences and perceptions of patients who read ambulatory visit notes written by a broad range of doctors, nurses, and other clinicians. METHODS: A total of 3 large US health systems in Boston, Seattle, and rural Pennsylvania conducted a Web-based survey of adult patients who used portal accounts and had at least 1 visit note available in a recent 12-month period. The main outcome measures included patient-reported behaviors and their perceptions concerning benefits versus risks. RESULTS: Among 136,815 patients who received invitations, 21.68% (29,656/136,815) responded. Of the 28,782 patient respondents, 62.82% (18,081/28,782) were female, 72.90% (20,982/28,782) were aged 45 years or older, 76.94% (22,146/28,782) were white, and 14.30% (4115/28,782) reported fair or poor health. Among the 22,947 who reported reading 1 or more notes, 3 out of 4 reported reading them for 1 year or longer, half reported reading at least 4 notes, and 37.74% (8588/22,753) shared a note with someone else. Patients rated note reading as very important for helping take care of their health (16,354/22,520, 72.62%), feeling in control of their care (15,726/22,515, 69.85%), and remembering the plan of care (14,821/22,516, 65.82%). Few were very confused (737/22,304, 3.3%) or more worried (1078/22,303, 4.83%) after reading notes. About a third reported being encouraged by their clinicians to read notes and a third told their clinicians they had read them. Less educated, nonwhite, older, and Hispanic patients, and individuals who usually did not speak English at home, were those most likely to report major benefits from note reading. Nearly all respondents (22,593/22,947, 98.46%) thought Web-based access to visit notes a good idea, and 62.38% (13,427/21,525) rated this practice as very important for choosing a future provider. CONCLUSIONS: In this first large-scale survey of patient experiences with a broad range of clinicians working in practices in which shared notes are well established, patients find note reading very important for their health management and share their notes frequently with others. Patients are rarely troubled by what they read, and those traditionally underserved in the United States report particular benefit. However, fewer than half of clinicians and patients actively address their shared notes during visits. As the practice continues to spread rapidly in the United States and internationally, our findings indicate that OpenNotes brings benefits to patients that largely outweigh the risks.
