Diagnosis and treatment of Wernicke's encephalopathy: A systematic literature review.

BACKGROUND: Wernicke's encephalopathy (WE) is a serious neurological disorder that is underdiagnosed. Despite limited clinical guidelines, the standard use of intravenous (IV) thiamine is underutilized and remains an area of research deserving much attention. OBJECTIVES: We conducted a systematic review using Medline, Embase, and CENTRAL databases to identify and summarize the literature on IV thiamine treatment in WE. Human studies with WE patients who received ≥100 mg of thiamine IV met inclusion criteria. Randomized controlled trials, cross-sectional studies, and case reports were included. RESULTS: A total of 27 studies were included: 20 case reports, five retrospective studies, one prospective study and one randomized control trial. Of the case reports, 11 (55%) cases were female, and the average age of all cases was 45 years (SD = 15). The other seven studies included 688 patients; the average age was 52 years (SD = 9), and 266 (38.7%) were female. Among the case reports, neurological and clinical findings were used to diagnose WE in 16 (80%) cases. MRI was utilized to diagnose 15 (75%) cases. 500 mg IV thiamine TID was reported in 12 case reports (60%). 18 (90%) of case reports had partial or complete resolution of symptoms following IV thiamine. CONCLUSION: IV thiamine can alleviate neurological symptoms, cognitive dysfunction, and brain imaging lesions associated with WE. We found key limitations in the evidence for IV thiamine and diagnostic standards for WE. Future targeted research should establish clear diagnostic and treatment guidelines for WE to prevent this serious condition from being underdiagnosed or undertreated.

Risk for postpartum depressive symptoms among pregnant women in a tertiary care setting with and without a positive COVID-19 test.

OBJECTIVE: This study systematically examines risk for postpartum depressive symptoms based on COVID-19 positivity status during pregnancy. METHODS: This is a retrospective matched cohort study of pregnant patients admitted to labor and delivery units from March through December 2020. Patients were administered three depression screening questions followed by the Edinburgh Postnatal Depression Scale (EPDS). RESULTS: 129 patients with positive COVID-19 tests (most with mild symptoms) were matched with 516 COVID-19 negative controls. We found no significant differences in rates of positive responses to screening questions (14/129, 10.9% vs. 72/516, 14.0%; p = .35) or EPDS scores >9 (6/97, 6.2% vs. 42/410, 10.2%; p = .22). Prior history of psychiatric illness was the only significant predictor of an EPDS score > 9 (adjOR 2.57, p = .002) or a positive brief screen for postpartum depressive symptoms (adjOR 2.93, p < .001). CONCLUSIONS: No significant differences in the rates for postpartum depressive symptoms were observed among pregnant women with and without a positive COVID-19 test during pregnancy, suggesting that testing positive for COVID-19 during pregnancy was not associated with an increased risk for the development of depressive symptoms during the acute postpartum period. Overall rates of postpartum depression symptoms were low, perhaps owing to the higher socioeconomic status of the sample.

A Qualitative Study of Religion and Spirituality in a Perinatal Psychiatry Inpatient Unit in the Southeast USA.

Religion and spirituality are important aspects of culture that can interact with mental health. They can also be central components of women's experiences during pregnancy and the postpartum period. This study aims to explore the role of religion and spirituality among women experiencing severe psychopathology during the perinatal period using qualitative interviews of women hospitalized during pregnancy or postpartum on an inpatient unit in the Southeast USA. The average age of participants was 34.2 and all identified as white, aside from one who identified as other. Though religious affiliation was varied, most participants were Christian. Each patient interviewed had a diagnosis of depressive disorder, among other comorbid diagnoses. Three main themes emerged in the subsequent analyses (1) spirituality providing a sense of healing and connectedness above and beyond religion, (2) patients seeking support from religious leaders, and (3) patients experiencing familial pressure to enact religion in a certain way, especially as it relates to child rearing. Clinical implications for each of the themes are explored.
