Post-COVID Wernicke's presenting as bilateral vision loss.

PURPOSE: This case report represents poor nutritional intake and vomiting secondary to COVID-19 resulting in Wernicke's syndrome and blindness. OBSERVATIONS: We report the case of a 36 year old with a post-COVID episode of acute-subacute onset bilateral blindness ultimately diagnosed as Wernicke's syndrome based on MRI findings and clinical response to high dose IV thiamine supplementation. CONCLUSIONS AND IMPORTANCE: Given this patient's dramatic presentation of no light perception vision in both eyes and resolution of symptoms with treatment, it is reasonable to consider thiamine deficiency in any individual who presents with acute-subacute onset vision loss, particularly when the history is suggestive of potential nutritional deficiency.

Pregnant women's experiences of social distancing behavioural guidelines during the Covid-19 pandemic 'lockdown' in the UK, a qualitative interview study.

BACKGROUND: Covid-19 triggered the rapid roll-out of mass social distancing behavioural measures for infection control. Pregnant women were categorised as 'at risk' requiring extra vigilance with behavioural guidelines. Their understanding and ability to adhere to recommendations was unknown. OBJECTIVES: To complete a behavioural analysis of the determinants of recommended social distancing behaviour in pregnant women, according to the 'capability, opportunity, motivation and behaviour' ('COM-B') model to inform the development of recommendations/materials to support pregnant women in understanding and adhering to behavioural guidelines. DESIGN: Qualitative interview study with pregnant women in the Bristol area (UK). METHODS: Semi-structured telephone/videoconference interviews were conducted following a topic guide informed by the COM-B model, transcribed verbatim and subjected to framework analysis. Infographic materials were iteratively produced with stakeholder consultation, to support pregnant women. RESULTS: Thirty-one women participated (selected for demographic range). Women reported adhering to social distancing recommendations and intended to continue. COM-B analysis identified gaps in understanding around risk, vulnerability, and the extent of required social distancing, as well as facilitators of social distancing behaviour (e.g. social support, motivation to stay safe, home environment/resources). Additional themes around detrimental mental health effects and changes to maternity healthcare from the social distancing measures were identified. Infographic resources (plus midwife report) addressing women's key concerns were produced and disseminated. CONCLUSIONS: The COM-B model provided useful details of determinants of pregnant women's adherence to social distancing behaviours. The confusion of what being 'at risk' meant and varying interpretation of what was expected indicates a need for greater clarity around categories and guidance. The loss of maternity care and negative mental health effects of social distancing suggest a growing area of unmet health needs to be addressed in future.

Maternal vaccines during the Covid-19 pandemic:A qualitative interview study with UK pregnant women.

BACKGROUND: There is suboptimal uptake of recommended maternal vaccines (pertussis and influenza) during pregnancy in the UK. The Covid-19 pandemic has impacted healthcare services, and potentially vaccine coverage, and brought the need for new vaccines to be tested and rolled out. OBJECTIVES: To explore: i) the impact of the Covid-19 pandemic on pregnant women's access to, and attitudes towards, routine maternal vaccines and; ii) women's attitudes towards testing Covid-19 vaccines on pregnant women and their personal willingness to take part in such a trial. DESIGN: Qualitative interview study with pregnant women in the Bristol and surrounding area (UK). METHODS: Semi-structured telephone/videoconference interviews were conducted (following a topic guide), transcribed verbatim and subjected to thematic analysis. RESULTS: Thirty-one pregnant women (selected for demographic range) were interviewed in April/May 2020. Participants felt the pandemic had elevated the importance of routine maternal vaccines, though women were concerned about safety management around appointment attendance. Women were wary of receiving a new Covid-19 vaccine, with most perceiving it as riskier than Covid-19 itself. CONCLUSIONS: It is important to maximise the safety and efficiency of maternity appointments to encourage uptake of routine maternal vaccines, and to communicate this well. For pregnant women to gain a new vaccine or participate in a vaccine trial, they need to be convinced that the risk posed by the virus is greater than any risk of receiving a new vaccine.
