DEcreased Cognitive functiON, NEurovascular CorrelaTes and myocardial changes in women with a history of pre-eclampsia (DECONNECT): research protocol for a cross-sectional pilot study

Introduction
Pre-eclampsia is a hypertensive disorder affecting up to 8% of pregnancies. After pre-eclampsia, women are at increased risk of cognitive problems, and cerebrovascular and cardiovascular disorders. These sequelae could result from microvascular dysfunction persisting after pre-eclampsia. This study will explore differences in cerebral and myocardial microvascular function between women after pre-eclampsia and women after normotensive gestation. We hypothesise that pre-eclampsia alters cerebral and myocardial microvascular functions, which in turn are related to diminished cognitive and cardiac performance.

Methods and analysis
The cross-sectional ‘DEcreased Cognitive functiON, NEurovascular CorrelaTes and myocardial changes in women with a history of pre-eclampsia’ (DECONNECT) pilot study includes women after pre-eclampsia and controls after normotensive pregnancy between 6 months and 20 years after gestation. We recruit women from the Queen of Hearts study, a study investigating subclinical heart failure after pre-eclampsia. Neuropsychological tests are employed to assess different cognitive domains, including attention, processing speed, and cognitive control. Cerebral images are recorded using a 7 Tesla MRI to assess blood–brain barrier integrity, perfusion, blood flow, functional and structural networks, and anatomical dimensions. Cardiac images are recorded using a 3 Tesla MRI to assess cardiac perfusion, strain, dimensions, mass, and degree of fibrosis. We assess the effect of a history of pre-eclampsia using multivariable regression analyses.

Ethics and dissemination
This study is approved by the Ethics Committee of Maastricht University Medical Centre (METC azM/UM, NL47252.068.14). Knowledge dissemination will include scientific publications, presentations at conferences and public forums, and social media.

Preference and retention of daily and event-driven pre-exposure prophylaxis for HIV prevention: a prospective cohort in Can Tho city, Viet Nam

Objective
Pre-exposure prophylaxis (PrEP) was introduced in Viet Nam in 2017, but data on oral PrEP preference and effective use beyond 3 months are limited. We aimed to evaluate PrEP preferences for PrEP, factors influencing uptake, choice and effective use, as well as barriers to PrEP.

Methods
This is a prospective cohort study in Can Tho, Viet Nam. Participants who were eligible for PrEP and provided informed consent were interviewed at baseline on demographic information, willingness to pay, reasons for choosing their PrEP regimen and the anticipated difficulties in taking PrEP and followed up at 3 months, 6 months and 12 months after PrEP initiation.

Findings
Between May 2020 and April 2021, 926 individuals at substantial risk for HIV initiated PrEP. Of whom 673 (72.7%) choose daily PrEP and 253 (27.3%) choose event-driven (ED)-PrEP. The majority of participants were men (92.7%) and only 6.8% were women and 0.5% were transgender women. Median participant age was 24 years (IQR 20–28) and 84.7% reported as exclusively same-sex relationship. The three most common reasons for choosing daily PrEP were effectiveness (24.3%) and unplanning for sex (22.9%). Those opting for ED-PrEP also cited effectiveness (22.7%), as well as convenience (18.0%) and easier effective use (12.0%). Only 7.8% of PrEP users indicated they were unwilling to pay for PrEP and 76.4% would be willing to pay if PrEP were less than US$15 per month. The proportion of user effectively using PrEP at 12 months was 43.1% and 99.2% in daily PrEP and ED-PrEP users, respectively.

Conclusions
ED-PrEP was preferred by more than a quarter of 23.5% of the participants and there was little concern about potential adverse events. High rates of effective use were reported by ED-PrEP users. Future research to inform implementation of PrEP in Viet Nam is needed to develop ways of measuring adherence to ED-PrEP more accurately and to understand and address difficulties in taking daily PrEP use.

Experience of multidisciplinary medical teams on humanistic palliative care in oncology wards: a descriptive qualitative study in Southern China

Objectives
This study aimed to explore the experiences of multidisciplinary medical teams in implementing humanistic palliative care within the oncology ward.

Design
Purposive and snowball sampling methods were used in this qualitative study, which involved conducting semistructured interviews to gather personal experiences from members of multidisciplinary medical teams providing humanistic palliative care in the oncology ward.

Setting
The research was conducted in the oncology ward of a tertiary hospital located in Foshan, China.

Participants
Participants included 4 doctors, 12 nurses and 2 medical social workers who form the multidisciplinary medical team responsible for delivering humanistic palliative care to patients with cancer in oncology wards.

Results
Phenomenological qualitative analysis yielded 3 main themes and 9 subthemes. The identified themes were as follows: (1) conceptual change, (2) concrete actions and (3) facilitators and barriers to the implementation of humanistic palliative care.

Conclusion
The findings suggest a need for strengthening humanistic consciousness among multidisciplinary palliative care teams working in oncology wards, although there has been a gradual improvement in humanistic care behaviours. Furthermore, facilitators and barriers coexist in the implementation of humanistic palliative care. Efforts should be directed towards refining mechanisms that promote humanistic palliative care, fostering the enthusiasm of healthcare professionals, conducting systematic training to enhance their humanistic care abilities and striving for improvements in the quality of medical services for the benefit of both patients and their families.

Integrated palliative care in oncology: a protocol for a realist synthesis

Introduction
Emerging evidence suggests improved quality of life, reduced symptom burden and lower health services costs when integrated palliative care and cancer care are implemented. Integrated palliative care aims to achieve care continuity by integrating organisational, administrative and clinical services involved in patient care networks. However, integrated palliative care for cancer is not common practice. This project, therefore, aims to understand how integrated palliative care and cancer care works in different healthcare settings (inpatient/outpatient), and for which groups of people (at what stage of the cancer journey), so we can develop guidance for optimal delivery.

Methods and analysis
We will conduct a realist synthesis to develop a programme theory of how integrated palliative care in cancer works, for whom and in what contexts to achieve improved symptom management and quality of life for patients and their families.
This realist synthesis will follow the five stages outlined by Pawson: (1) locating existing theories, (2) searching for evidence, (3) article selection, (4) extracting and organising data and (5) synthesising the evidence and drawing conclusions. We will work closely with our expert stakeholder group, which includes health and social care professionals providing palliative care and oncology; management and policy groups and members of the public and patients. We will adhere to RAMESES quality standards for undertaking a realist synthesis.

Ethics and dissemination
Ethics approval for this project is not required.
The realist synthesis will develop a programme theory that provides clarity on the optimal delivery of palliative care for adults with cancer. We will use the programme theory to coproduce guidance and user-friendly outputs, working with stakeholders to inform delivery of best practice. Findings will inform further research in integrated palliative care and cancer. Stakeholder engagement will assist in the dissemination of our findings.
