RESUMO

Pregnant women experienced disruptions in their prenatal care during the coronavirus disease-2019 (COVID-19) pandemic. While there is emerging research about the impact of COVID-19 on experiences of pregnancy, the majority of studies that have reported on prenatal care and birth during COVID-19 have not incorporated the first-person accounts of Black women. The purpose of this mixed-methods study was to explore the perspectives of Black women on prenatal care, labor, and birth during the pandemic. A total of 33 participants completed questionnaires. Fourteen of these 33 women and an additional 2 participated in qualitative interviews. Descriptive statistics and a mixed-methods analysis were employed. Participants expressed disappointment about disruptions in their experiences of pregnancy including the way their prenatal care was experienced, cancellation of planned "rites of passage," and visitor policy restrictions during and after the birth. Forty-five percent of participants reported being worried about getting COVID-19 and (61%) about their infant getting COVID-19. Many participants experienced a sense of loss that may permeate through other aspects of their lives. Providing extra support and points of contact can help lessen feelings of isolation during the pandemic and can also offer more explanation for rapidly changing policies and procedures.

RESUMO

OBJECTIVE: To compare and contrast pregnant, Black women's voices with quantitative measures of racial residential segregation, neighborhood disorder, and racial discrimination. DESIGN AND SAMPLE: Using a convergent design for the parent study, surveys and qualitative interviews were completed by Black pregnant women (n = 27). MEASURES: Content analysis was conducted and data were analyzed to assess for congruency or divergence for each concept related to structural racism (racial residential segregation, neighborhood disorder, and discrimination). RESULTS: No single concept had 100% agreement across qualitative and quantitative approaches. Participants disclosed experiences during some interviews that were not captured by the surveys. The qualitative interviews offered a more detailed description of the concepts which along with the quantitative measures, provided insights about how participants perceived these mechanisms. DISCUSSION: While important relationships about the mechanisms of structural racism and preterm birth can be examined using a single approach, using mixed methods can offer more insights about how those most impacted by preterm birth relate to these mechanisms. Future work will best add to the understanding of structural racism and preterm birth when study measures accurately reflect the experiences of the people who experience racism.

RESUMO

OBJECTIVE: To report the clinical, radiological, and immunological association of demyelinating disorders with anti­Nmethyl- D-aspartate receptor (NMDAR) encephalitis. METHODS: Clinical and radiological analysis was done of a cohort of 691 patients with anti-NMDAR encephalitis. Determination of antibodies to NMDAR, aquaporin-4 (AQP4), and myelin oligodendrocyte glycoprotein (MOG) was performed using brain immunohistochemistry and cell-based assays. RESULTS: Twenty-three of 691 patients with anti-NMDAR encephalitis had prominent magnetic resonance imaging (MRI) and/or clinical features of demyelination. Group 1 included 12 patients in whom anti-NMDAR encephalitis was preceded or followed by independent episodes of neuromyelitis optica (NMO) spectrum disorder (5 cases, 4 anti-AQP4 positive) or brainstem or multifocal demyelinating syndromes (7 cases, all anti-MOG positive). Group 2 included 11 patients in whom anti-NMDAR encephalitis occurred simultaneously with MRI and symptoms compatible with demyelination (5 AQ4 positive, 2 MOG positive). Group 3 (136 controls) included 50 randomly selected patients with typical anti-NMDAR encephalitis, 56 with NMO, and 30 with multiple sclerosis; NMDAR antibodies were detected only in the 50 anti-NMDAR patients, MOG antibodies in 3 of 50 anti-NMDAR and 1 of 56 NMO patients, and AQP4 antibodies in 48 of 56 NMO and 1 of 50 anti-NMDAR patients (p<0.0001 for all comparisons with Groups 1 and 2). Most patients improved with immunotherapy, but compared with anti-NMDAR encephalitis the demyelinating episodes required more intensive therapy and resulted in more residual deficits. Only 1 of 23 NMDAR patients with signs of demyelination had ovarian teratoma compared with 18 of 50 anti-NMDAR controls (p50.011). INTERPRETATION: Patients with anti-NMDAR encephalitis may develop concurrent or separate episodes of demyelinating disorders, and conversely patients with NMO or demyelinating disorders with atypical symptoms (eg, dyskinesias, psychosis) may have anti-NMDAR encephalitis.

RESUMO

PURPOSE: Non-Hispanic Black women in the United States experience disproportionately higher rates of adverse birth outcomes including preterm birth and low birth weight infants compared with White women. Racial discrimination has been associated with these adverse outcomes. However, not all Black women experience discrimination in the same way. The majority of studies that report on the relationship between racial discrimination and maternal health have used quantitative methods that may present a monolithic understanding of this relationship. Qualitative methods, specifically those that incorporate intersectionality, may illuminate the nuances in pregnant Black women's experiences of discrimination. We present a qualitative analysis of Black women's experiences of racial discrimination and pregnancy to shed light on some of these complexities. STUDY DESIGN AND METHODS: Qualitative interviews that addressed racial discrimination and pregnancy were conducted as part of a larger study of pregnant Black women that examined social support, neighborhood disorder, and racial discrimination. Interviews were coded for descriptions of racial discrimination and within and across case analysis was conducted. RESULTS: Women described varying experiences of racial discrimination in different contexts. Shielding emerged as a recurring theme in women's accounts of dealing with racial discrimination during pregnancy. CLINICAL IMPLICATIONS: Nurses engaged in maternity care need an understanding of how pregnant Black women experience racial discrimination in different ways. Black women may be likely to take personal responsibility for managing discrimination-related stress in pregnancy as a consequence of direct experiences of discrimination. Nurses can support pregnant Black women by recognizing varied experiences of racial discrimination, and by not blaming them for experiences or potential resultant outcomes.

RESUMO

OBJECTIVE: To describe and understand exercise practices, beliefs about exercise, support for exercise, barriers to exercise, and preferences for a group exercise program in the context of individual and environmental factors among Black women during pregnancy. DESIGN: Mixed-methods design. SETTING: Large university-affiliated urban midwifery practice. PARTICIPANTS: Fourteen Black women who were pregnant. METHODS: We conducted semistructured interviews to determine participants' exercise practices, beliefs about exercise while pregnant, exercise support and barriers, and preferences for a group pregnancy exercise program. Participants also completed self-report measures for exercise, neighborhood environment, symptoms of depression, and sociodemographic characteristics. We used matrices to facilitate integrated analysis of the interview and self-report data to determine areas of concordance and discordance among the data sources and to note patterns in the data. RESULTS: We identified and described themes that represented concepts in our data: Exercise Misinformation and Folklore, Supportfor Exercise While Pregnant, Barriers to Exercise While Pregnant, Perceived Health Benefits, and Exercise Program Preferences. Data diverged for some participants on neighborhood as a barrier to exercise. Except for the two participants with high levels of symptoms of depression, data converged regarding symptoms of depression as a barrier to exercise. CONCLUSION: Health care providers can successfully promote exercise if they provide education about exercise during pregnancy, help pregnant women overcome barriers to exercise, prompt women to exercise with partners for tangible and social support while pregnant, and refer women to exercise programs for pregnant women if available.

RESUMO

OBJECTIVE: To construct a grading score that predicts neurologic function 1 year after diagnosis of anti-NMDA receptor (NMDAR) encephalitis. METHODS: Three hundred eighty-two patients with detailed information and functional status at 1 year were studied. Factors associated with poor status (defined as modified Rankin Scale score ≥3) were identified and incorporated into a multivariate logistic regression model. This model was used to develop a 5-point prediction score, termed the anti-NMDAR Encephalitis One-Year Functional Status (NEOS) score. RESULTS: Intensive care unit admission (p < 0.001), treatment delay >4 weeks (p = 0.012), lack of clinical improvement within 4 weeks (p < 0.001), movement disorder (p = 0.001), central hypoventilation (p < 0.001), elevated CSF white blood cell count (p < 0.001), elevated CSF protein level (p = 0.027), and abnormal MRI (p = 0.002) were associated with 1-year functional status in univariate analysis. Intensive care unit admission, treatment delay >4 weeks, lack of clinical improvement within 4 weeks, abnormal MRI, and CSF white blood cell count >20 cells/µL were independent predictors for outcome in multivariate regression modeling. These 5 variables were assigned 1 point each to create the NEOS score. NEOS score strongly associated with the probability of poor functional status at 1 year (3% for 0 or 1 point to 69% for 4 or 5 points, p < 0.001). CONCLUSIONS: The NEOS score accurately predicts 1-year functional status in patients with anti-NMDAR encephalitis. This score could help estimate the clinical course following diagnosis and may aid in identifying patients who could benefit from novel therapies.

RESUMO

OBJECTIVE: We tested whether antibody screening samples of patients with suspected autoimmune encephalitis with additional research assays would improve the detection of autoimmune encephalitis compared with standard clinical testing alone. METHODS: We examined 731 samples (333 CSF, 182 sera, and 108 pairs) from a cohort of 623 patients who were tested for CNS autoantibodies by the University of Pennsylvania clinical laboratory over a 24-month period with cell-based assays (CBAs) on commercially obtained slides of fixed cells for antibodies to NMDA receptor (NMDAR), α-amino-3-hydroxy-5-methyl-4-isoxazolepropionic acid receptor (AMPAR), γ-aminobutyric acid-B receptor (GABABR), leucine-rich glioma-inactivated 1 (LGI1), contactin-associated protein-like 2 (Caspr2), and glutamic acid decarboxylase (GAD65). In parallel, our research laboratory screened all samples for reactivity to brain sections and for anti-NMDAR using in-house CBAs. Samples with brain reactivity or positive clinical studies were examined with CBAs for a larger panel of antibodies. RESULTS: The clinical laboratory reported positive findings for NMDAR (80 samples), GAD65 (8), LGI1 (5), Caspr2 (2), and GABABR (4). Sixty-five serum samples and 32 CSF samples were indeterminate for one or more antibodies. In our research laboratory, all but 4 positive results were confirmed, 88 of 97 indeterminate results were resolved, and 15 additional samples were found positive (10 NMDAR, 1 AMPAR, 3 LGI1, and 1 Caspr2). Clinical information supported these diagnoses. Overall, informative autoantibodies were detected in 15.5% of cases. CONCLUSIONS: Standard clinical laboratory kits were specific, but some tests were insensitive and prone to indeterminate results. Screening with immunohistochemistry for reactivity to brain sections, followed by additional CBAs for cases with brain reactivity, improves the diagnostic accuracy of testing for autoimmune encephalitis.

RESUMO

BACKGROUND: Anti-N-methyl-d-aspartate (NMDA) receptor encephalitis is a severe but treatable autoimmune disorder which diagnosis depends on sensitive and specific antibody testing. We aimed to assess the sensitivity and specificity of serum and CSF antibody testing in patients with anti-NMDA receptor encephalitis, and the relation between titres, relapses, outcome, and epitope repertoire. METHODS: In this observational study, we used rat brain immunohistochemistry and cell-based assays (CBA) with fixed or live NMDA receptor-expressing cells to determine the sensitivity and specificity of antibody testing in paired serum and CSF samples. Samples were obtained at diagnosis from patients with anti-NMDA receptor encephalitis and from control participants worldwide. We deemed a patient to be antibody positive if their serum, their CSF, or both tested positive with both immunohistochemistry and CBA techniques; we determined titres with serial sample dilution using brain immunohistochemistry. We examined samples from 45 patients (25 with good outcome [modified Rankin Scale, mRS 0-2], ten with poor outcome [mRS 3-6], and ten with relapses) at three or more timepoints. We determined the epitope repertoire in the samples of 23 patients with CBA expressing GluN1-NMDA receptor mutants. FINDINGS: We analysed samples from 250 patients with anti-NMDA receptor encephalitis and 100 control participants. All 250 patients had NMDA receptor antibodies in CSF but only 214 had antibodies in serum (sensitivity 100.0% [98.5-1000%] vs 85.6% [80.7-89.4%], p<0.0001). Serum immunohistochemistry testing was more often in agreement with CBA with fixed cells (77 [71%] of 108) than with CBA with live cells (63 [58%] of 108, p=0.0056). In multivariable analysis, CSF and serum titres were higher in patients with poor outcome than in those with good outcome (CSF dilution 340 vs 129, difference 211, [95% CI 1-421], p=0.049; serum dilution 7370 vs 1243, difference 6127 [2369-9885], p=0.0025), and in patients with teratoma than in those without teratoma (CSF 395 vs 110, difference 285 [134-437], p=0.0079; serum 5515 vs 1644, difference 3870 [548-7193], p=0.024). Over time there was a decrease of antibody titres in the 35 patients with good or poor outcome and samples followed at three timepoints regardless of outcome (from diagnosis to last follow-up: CSF 614 to 76, difference 538 [288-788]; serum 5460 to 1564, difference 3896 [2428-5362]; both p<0.0001). Relapses were associated with a change in titre more often in CSF than in serum (14 of 19 vs seven of 16, p=0.037). After recovery, 24 of 28 CSF samples and 17 of 23 serum samples from patients remained antibody positive. Patients' antibodies targeted a main epitope region at GluN1 aminoacid 369; the epitope repertoire did not differ between patients with different outcomes, and did not change during relapses. INTERPRETATION: The sensitivity of NMDA receptor antibody testing is higher in CSF than in serum. Antibody titres in CSF and serum were higher in patients with poor outcome or teratoma than in patients with good outcome or no tumour. The titre change in CSF was more closely related with relapses than was that in serum. These findings emphasise the importance of including CSF in antibody studies, and that antibody titres can complement clinical assessments.

RESUMO

BACKGROUND: Increasing evidence suggests that seizures and status epilepticus can be immune-mediated. We aimed to describe the clinical features of a new epileptic disorder, and to establish the target antigen and the effects of patients' antibodies on neuronal cultures. METHODS: In this observational study, we selected serum and CSF samples for antigen characterisation from 140 patients with encephalitis, seizures or status epilepticus, and antibodies to unknown neuropil antigens. The samples were obtained from worldwide referrals of patients with disorders suspected to be autoimmune between April 28, 2006, and April 25, 2013. We used samples from 75 healthy individuals and 416 patients with a range of neurological diseases as controls. We assessed the samples using immunoprecipitation, mass spectrometry, cell-based assay, and analysis of antibody effects in cultured rat hippocampal neurons with confocal microscopy. FINDINGS: Neuronal cell-membrane immunoprecipitation with serum of two index patients revealed GABAA receptor sequences. Cell-based assay with HEK293 expressing α1/ß3 subunits of the GABAA receptor showed high titre serum antibodies (>1:160) and CSF antibodies in six patients. All six patients (age 3-63 years, median 22 years; five male patients) developed refractory status epilepticus or epilepsia partialis continua along with extensive cortical-subcortical MRI abnormalities; four patients needed pharmacologically induced coma. 12 of 416 control patients with other diseases, but none of the healthy controls, had low-titre GABAA receptor antibodies detectable in only serum samples, five of them also had GAD-65 antibodies. These 12 patients (age 2-74 years, median 26.5 years; seven male patients) developed a broader spectrum of symptoms probably indicative of coexisting autoimmune disorders: six had encephalitis with seizures (one with status epilepticus needing pharmacologically induced coma; one with epilepsia partialis continua), four had stiff-person syndrome (one with seizures and limbic involvement), and two had opsoclonus-myoclonus. Overall, 12 of 15 patients for whom treatment and outcome were assessable had full (three patients) or partial (nine patients) response to immunotherapy or symptomatic treatment, and three died. Patients' antibodies caused a selective reduction of GABAA receptor clusters at synapses, but not along dendrites, without altering NMDA receptors and gephyrin (a protein that anchors the GABAA receptor). INTERPRETATION: High titres of serum and CSF GABAA receptor antibodies are associated with a severe form of encephalitis with seizures, refractory status epilepticus, or both. The antibodies cause a selective reduction of synaptic GABAA receptors. The disorder often occurs with GABAergic and other coexisting autoimmune disorders and is potentially treatable.

RESUMO

OBJECTIVE: To describe the clinical features and outcome of anti-NMDA receptor (NMDAR) encephalitis in patients ≥45 years old. METHOD: Observational cohort study. RESULTS: In a cohort of 661 patients with anti-NMDAR encephalitis, we identified 31 patients ≥45 years old. Compared with younger adults (18-44 years), older patients were more often male (45% vs. 12%, p < 0.0001), had lower frequency of tumors (23% vs. 51%, p = 0.002; rarely teratomas), had longer median time to diagnosis (8 vs 4 weeks, p = 0.009) and treatment (7 vs. 4 weeks, p = 0.039), and had less favorable outcome (modified Rankin Scale score 0-2 at 2 years, 60% vs. 80%, p < 0.026). In multivariable analysis, younger age (odds ratio [OR] 0.15, confidence interval [CI] 0.05-0.39, p = 0.0001), early treatment (OR 0.60, CI 0.47-0.78, p < 0.0001), no need for intensive care (OR 0.09, CI 0.04-0.22, p < 0.0001), and longer follow-up (p < 0.0001) were associated with good outcome. Rituximab and cyclophosphamide were effective when first-line immunotherapies failed (OR 2.93, CI 1.10-7.76, p = 0.031). Overall, 60% of patients older than 45 years had full or substantial recovery at 24 months follow-up. CONCLUSIONS: Anti-NMDAR encephalitis is less severe in patients ≥45 years old than in young adults, but the outcome is poorer in older patients. In this age group, delays in diagnosis and treatment are more frequent than in younger patients. The frequency of underlying tumors is low, but if present they are usually carcinomas instead of teratomas in younger patients. Early and aggressive immunotherapy will likely improve the clinical outcome.

RESUMO

BACKGROUND: Anti-NMDA receptor (NMDAR) encephalitis is an autoimmune disorder in which the use of immunotherapy and the long-term outcome have not been defined. We aimed to assess the presentation of the disease, the spectrum of symptoms, immunotherapies used, timing of improvement, and long-term outcome. METHODS: In this multi-institutional observational study, we tested for the presence of NMDAR antibodies in serum or CSF samples of patients with encephalitis between Jan 1, 2007, and Jan 1, 2012. All patients who tested positive for NMDAR antibodies were included in the study; patients were assessed at symptom onset and at months 4, 8, 12, 18, and 24, by use of the modified Rankin scale (mRS). Treatment included first-line immunotherapy (steroids, intravenous immunoglobulin, plasmapheresis), second-line immunotherapy (rituximab, cyclophosphamide), and tumour removal. Predictors of outcome were determined at the Universities of Pennsylvania (PA, USA) and Barcelona (Spain) by use of a generalised linear mixed model with binary distribution. RESULTS: We enrolled 577 patients (median age 21 years, range 8 months to 85 years), 211 of whom were children (<18 years). Treatment effects and outcome were assessable in 501 (median follow-up 24 months, range 4-186): 472 (94%) underwent first-line immunotherapy or tumour removal, resulting in improvement within 4 weeks in 251 (53%). Of 221 patients who did not improve with first-line treatment, 125 (57%) received second-line immunotherapy that resulted in a better outcome (mRS 0-2) than those who did not (odds ratio [OR] 2·69, CI 1·24-5·80; p=0·012). During the first 24 months, 394 of 501 patients achieved a good outcome (mRS 0-2; median 6 months, IQR 2-12) and 30 died. At 24 months' follow-up, 203 (81%) of 252 patients had good outcome. Outcomes continued to improve for up to 18 months after symptom onset. Predictors of good outcome were early treatment (0·62, 0·50-0·76; p<0·0001) and no admission to an intensive care unit (0·12, 0·06-0·22; p<0·0001). 45 patients had one or multiple relapses (representing a 12% risk within 2 years); 46 (67%) of 69 relapses were less severe than initial episodes (p<0·0001). In 177 children, predictors of good outcome and the magnitude of effect of second-line immunotherapy were similar to those of the entire cohort. INTERPRETATION: Most patients with anti-NMDAR encephalitis respond to immunotherapy. Second-line immunotherapy is usually effective when first-line treatments fail. In this cohort, the recovery of some patients took up to 18 months.

RESUMO

RATIONALE: Much of what is known about college drinking comes from self-report survey data. Such surveys typically ask students to indicate how many drinks they consume within a given period of time. It is currently unclear whether college students and researchers use similar operational definitions of a single drink. This information is critical given the widespread reliance on survey data for assessing the correlates and consequences of college drinking. OBJECTIVES: This study investigated whether college students define standard drink volumes in a way that is consistent with the operational definitions commonly used by researchers. METHODS: Students (n = 106) were administered an alcohol survey and then asked to perform three tasks. The tasks involved free-pouring fluid into empty cups of different sizes and estimating the volume of a single beer, a shot of liquor, or the amount of liquor in a mixed drink. The volumes poured by students then were compared with standards used in a well-known nationwide survey (i.e., 12 oz of beer and 1.25 oz of liquor in a shot or mixed drink). RESULTS: In every cup size of every task, students overestimated how much fluid they should pour to create a standard drink. In all three tasks, the magnitude of the discrepancy increased with cup size. Collapsed across cup sizes, students overpoured shots by 26%, mixed drinks by 80%, and beer by 25%. When a more liberal serving size of liquor (1.5 oz) was used as the standard, the results of the mixed drink task remained unchanged. However, the volumes poured by students during the shot free-pour task differed from the standard in only one cup size. CONCLUSIONS: The data suggest that college students drink more alcohol than indicated by their survey responses, raising questions about the validity of widely used alcohol surveys. Efforts to educate students about the alcohol content of standard drinks should be enhanced.
