Chronic Thromboembolic Pulmonary Hypertension: the therapeutic assessment.

Chronic Thromboembolic Pulmonary Hypertension (CTEPH) is a severe and complex condition that evolves from unresolved pulmonary embolism, leading to fibrotic obstruction of pulmonary arteries, pulmonary hypertension, and potential right heart failure. The cornerstone of CTEPH management lies in a multifaceted therapeutic approach tailored to individual patient profiles, reflecting the disease's heterogeneity. This review delves into the current therapeutic strategies for CTEPH, including surgical pulmonary endarterectomy (PEA), balloon pulmonary angioplasty (BPA), and targeted pharmacological treatments such as PDE5 inhibitors, endothelin receptor antagonists, sGC stimulators, and prostanoids. Lifelong anticoagulation is also highlighted as a preventive strategy against recurrent thromboembolism. Special emphasis is placed on the interdisciplinary nature of CTEPH care, necessitating collaboration among PEA surgeons, BPA interventionists, PH specialists, and thoracic radiologists to ensure comprehensive treatment planning and execution. The review underscores the importance of selecting an appropriate treatment modality based on the patient's specific disease characteristics and the evolving landscape of CTEPH treatment, aiming to improve patient outcomes through integrated care strategies.

COVID-19, Nutrients and Lifestyle Eating Behaviors: A Narrative Review.

BACKGROUND: COVID-19 infection, caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), quickly emerged as the most significant event of the new millennium. A balanced diet seems to ensure the proper functioning of the immune system and plays a fundamental role in the prevention of viral disease, inflammation, or thrombosis. The principal aim of this secondary study was to investigate the relationship between nutrients, lifestyle eating behaviors, and SARS-CoV-2 infection. METHODS: A narrative review was conducted in the PubMed-Medline database, analyzing primary studies. RESULTS: Our review identified 21 relevant studies: 13 focused on vitamins, 1 on omega-3 supplementation, 1 on probiotics, and 6 on lifestyle and dietary behaviors. Vitamin supplementation has shown promise in attenuating COVID-19 symptoms and reducing mortality risk. Specifically, vitamin D has demonstrated efficacy in enhancing immune responses among patients with the disease. While preliminary evidence suggests the potential benefits of omega-3 and probiotic supplementation in improving health outcomes for COVID-19 outpatients, further research is needed to solidify these findings. CONCLUSIONS: The lifestyle changes imposed by lockdown measures have adversely affected psychological well-being and exacerbated health issues associated with reduced physical activity and poor dietary habits.

Two Decades of Medical Spanish Education: A Narrative Review.

Purpose: Education on medical Spanish, defined as the use of Spanish by clinicians for communication with patients, has proliferated rapidly since the first guidelines were published in 2008. This study aims to characterize the scope of the field, identify gaps, and propose emerging questions for future study. Method: The authors conducted a narrative review of the medical Spanish education literature published from 2000 to 2023. First, a comprehensive search algorithm was developed across three databases (Medline, Scopus, and Web of Science Core Collection) and conducted on August 2, 2023. Two reviewers then independently assessed articles for inclusion/exclusion and subsequent categorization of included articles. Results: The search identified 1,303 articles, and authors added ten articles from other sources. A total of 138 individual articles were included in the final categorization and sub-analysis. There has been an upward trend in the number of articles published yearly since 2000. Most publications were educational interventions (67/138, 49%), followed by commentaries/perspectives (27/138, 20%), proficiency testing (17/138, 13%), needs assessments (16/138, 12%), reviews (6/138, 4%), and vocabulary analyses (5/138, 4%). Slightly over half of publications (72/138, 52%) were centered on physicians or physicians-in-training, with 23 (17%) articles applicable across health professions, and a few focused on pharmacists, nurses, physical therapists, psychologists, physician assistants, and genetic counselors. The vast majority (119/138, 86%) were published in medical/scientific journals and 19 (14%) in language/humanities journals. All but two first authors were affiliated with United States institutions, representing 30 states and Puerto Rico. Conclusions: Over the past two decades, many medical Spanish educational interventions have been published, and several assessment tools have been developed and validated. Gaps remain in evaluation data to demonstrate course effectiveness, the use of pedagogical frameworks to guide curricula, faculty development opportunities, and the role of heritage Spanish learners. Future work should address medical Spanish gaps in health professions and medical specialties, explore patient-engaged approaches to research, and evaluate longitudinal outcomes.

An assessment of narrative operative reports for Wilms tumor resection using consensus component criteria.

INTRODUCTION: Precision in surgical documentation is essential to avoid miscommunication and errors in patient care. Synoptic operative reports are more precise than narrative operative reports, however they have not been widely implemented in pediatric surgical oncology. To assess the need for implementation of synoptic operative reports in pediatric surgical oncology, we examined the completeness of narrative operative reports in patients undergoing resection of Wilms tumor. METHODS: We conducted a retrospective review of narrative operative reports for resection of Wilms tumor at a single pediatric oncology center from January 2022 through July 2023. Primary outcomes were the presence or absence of 11 key operative report components. Inclusion rates were calculated as simple percentages. Unilateral and bilateral operations were considered. RESULTS: Thirty-five narrative reports for Wilms tumor resection were included. The most consistently documented operative report components were estimated blood loss, indication for surgery, intraoperative complications, and specimen naming (100% documentation rates). Documentation of lymph node sampling was present in 94.3% of reports. The least consistently documented components were assessment of intraoperative tumor spillage, completeness of resection, metastatic disease, and assessment of vascular involvement (each ≤40% documentation rate). All 11 key components were documented in three reports. CONCLUSIONS: Even at a large tertiary pediatric oncology referral center, narrative operative reports for pediatric Wilms tumor resection were found to be frequently missing important components of surgical documentation. Often, these were omissions of negative findings. Utilization of synoptic operative reports may be able to reduce these gaps.

A palliative care approach for adult non-cancer patients with life-limiting illnesses is cost-saving or cost-neutral: a systematic review of RCTs.

BACKGROUND: Patients living with life-limiting illnesses other than cancer constitute the majority of patients in need of palliative care globally, yet most previous systematic reviews of the cost impact of palliative care have not exclusively focused on this population. Reviews that tangentially looked at non-cancer patients found inconclusive evidence. Randomised controlled trials (RCTs) are the gold standard for treatment efficacy, while total health care costs offer a comprehensive measure of resource use. In the sole review of RCTs for non-cancer patients, palliative care reduced hospitalisations and emergency department visits but its effect on total health care costs was not assessed. The aim of this study is to review RCTs to determine the difference in costs between a palliative care approach and usual care in adult non-cancer patients with a life-limiting illness. METHODS: A systematic review using a narrative synthesis approach. The protocol was registered with PROSPERO prospectively (no. CRD42020191082). Eight databases were searched: Medline, CINAHL, EconLit, EMBASE, TRIP database, NHS Evidence, Cochrane Library, and Web of Science from inception to January 2023. Inclusion criteria were: English or German; randomised controlled trials (RCTs); adult non-cancer patients (> 18 years); palliative care provision; a comparator group of standard or usual care. Quality of studies was assessed using Drummond's checklist for assessing economic evaluations. RESULTS: Seven RCTs were included and examined the following diseases: neurological (3), heart failure (2), AIDS (1) and mixed (1). The majority (6/7) were home-based interventions. All studies were either cost-saving (3/7) or cost-neutral (4/7); and four had improved outcomes for patients or carers and three no change in outcomes. CONCLUSIONS: In a non-cancer population, this is the first systematic review of RCTs that has demonstrated a palliative care approach is cost-saving or at least cost-neutral. Cost savings are achieved without worsening outcomes for patients and carers. These findings lend support to calls to increase palliative care provision globally.

Effects of Non-Thermal Dielectric Barrier Discharge Plasma on Human Fibroblasts: A Narrative Review.

Objectives: Fibroblasts are among the most critical connective tissue cells in almost all tissues and organs. Enhancement of fibroblast differentiation, proliferation, and morphogenesis is of paramount importance in tissue regeneration and wound healing. The non-thermal dielectric barrier discharge (DBD) plasma technology has recently gained interest due to its extensive applications and multiple biological effects. This review article outlines the applications of DBD plasma in dentistry, and its biological effects on human fibroblasts. Materials and Methods: Relevant keywords were searched in PubMed, Ovid, and Google Scholar online databases. The search strategy resulted in selection of 7 studies according to the eligibility criteria. Results: Most studies reported increased cell proliferation and viability after the application of DBD plasma. Four studies that focused on the development of adhesion-related appendages examined the morphology of fibroblast cells, including the creation of vinculin, protrusion, and actin cytoskeleton. Expression of cyclin D1/P27 genes and genes associated with adhesion and cell attachments was also reported in two studies. Conclusion: This narrative review discussed the effects of DBD plasma technology on proliferation and behavior of human fibroblasts, and reviewed the available articles in this regard. More in vivo studies are required to understand the exact effects of this emerging technology on human mesenchymal tissues.

A Systematic Review and Narrative Synthesis Examining the Facilitators and Barriers of Psychological Intervention Delivery in Crisis Resolution Home Treatment Teams.

BACKGROUND: Mental health crisis rates in the United Kingdom are on the rise. The emergence of community mental health models, such as Crisis Resolution Home Treatment Teams (CRHTTs), offers a vital pathway to provide intensive assessment and treatment to individuals in their homes, including psychological interventions. Previous qualitative literature has identified facilitators and barriers to the implementation of psychological interventions within CRHTT settings; however, a synthesis of this literature has not yet been conducted. To address this gap, a systematic review was undertaken with the aim of identifying the reported facilitators and barriers of implementing evidence-based psychological interventions in CRHTTs. METHOD: A systematic review and narrative synthesis were conducted. Studies were included if they examined the implementation of evidence-based psychological interventions in a CRHTT setting. The study population had to be 18 and over and could include healthcare professionals working in CRHTTs, service users of CRHTTs, or family and carers of CRHTT service users. Studies of any formal research methodology were included. Four databases were searched (MEDLINE, CINAHL Plus, Embase and PsycINFO), along with Google Scholar, to identify eligible studies. RESULTS: Six studies were identified, using mixed qualitative and quantitative methodologies, with the predominant focus being the exploration of stakeholder perspectives on care implementation within CRHTTs, encompassing aspects including but not restricted to psychological care implementation. The literature was deemed to be of moderate to high quality. Facilitators included adapting psychological therapies, prioritizing the therapeutic relationship, increasing psychological skills and training of CRHTT staff and psychologically informed CRHTT models. The barriers identified included a medical model bias within teams, resource constraints and elements pertaining to CRHTT services. CONCLUSIONS: Further robust research in this area is imperative. We recommend that future research be implemented in the form of service evaluations and randomized controlled trials (RCTs) and that the principles of implementation science be used to assess and develop the evidence base for psychological intervention delivery in CRHTTs.

"Look at You Having Fun With Your Markers in Here!": Child Life Specialists' Countering of Infantilizating Narratives in Adult Oncology.

Child life specialists are clinically trained and educated healthcare professionals who work in both healthcare environments and the community to address the needs of ill children and their families. However, child life specialists have previously reported potential for their role, responsibilities, and scope of practice to be misunderstood by their clinical colleagues. Using a narrative methodology, this paper presents the composite narrative of Diane, whose story encompasses the stories of the four child life specialists working in adult oncology environments in Ontario, Canada. Diane's narrative is a counter-story, which counters common assumptions, beliefs, and attitudes about child life specialists. Through spending significant time narrating the multitude of tasks that are encompassed within her scope of care, Diane reaffirms her identity as a valuable member of an interprofessional adult oncology team and counters infantilizing assumptions that she is merely a babysitter or child entertainer. Her story highlights how, while the introduction of child life specialists to adult healthcare environments is new, the work they do is of great benefit to families and their children. The lack of understanding from clinical colleagues of the role of child life specialists, however, hinders not only the development of relationships between colleagues, but also the care for these families.

Teplizumab's immunomodulatory effects on pancreatic ß-cell function in type 1 diabetes mellitus.

This review explores the immunomodulatory potential of Teplizumab and its impact on pancreatic ß-cell function in T1D. Characterized by the autoimmune destruction of insulin-producing beta cells, T1D's management involves maintaining glycemic control through exogenous insulin. Teplizumab, a humanized monoclonal antibody targeting the CD3 antigen, has shown promise in delaying T1D onset and preserving residual ß-cell function. The review employs a narrative approach, synthesizing evidence from diverse clinical trials and studies gathered through a meticulous literature search. It scrutinizes Teplizumab's mechanisms of action, including its influence on autoreactive CD8 + T cells and regulatory T cells, offering insights into its immunological pathways. The synthesis of findings from various trials demonstrates Teplizumab's efficacy in preserving C-peptide levels and reducing exogenous insulin requirements, particularly in recent-onset T1D. Considering Teplizumab's real-world implications, the paper addresses potential obstacles, including side effects, patient selection criteria, and logistical challenges. It also emphasizes exploring combination therapies and personalized treatment strategies to maximize Teplizumab's benefits. The review contributes a nuanced perspective on Teplizumab's clinical implications and future directions in T1D management, bridging theoretical understanding with practical considerations.

Utilizing a multisystemic model of resilience to synthesize research in youth with inflammatory bowel disease: a narrative review.

Background and Objective: The study of resilience in youth with inflammatory bowel disease (IBD) is in early stages. The current review aims to illustrate how the use of a multisystemic framework may serve as a developmental and disease-appropriate framework for conceptualizing and designing resilience research for youth with IBD. Methods: This is a narrative review; therefore, a comprehensive and systematic literature search was not conducted. Rather, the current paper aims to map selected existing literature to a multisystemic model as exemplars of how the model may be used in youth with IBD. Relevant literature was reviewed, synthesized, and mapped onto the proposed multi-systemic framework. Key Content and Findings: The current review considers existing literature across three proposed dimensions of resilience: contexts of risk exposure, protective and promotive factors/processes, and desired outcomes. Review of each dimension includes consideration of selected existing literature to explain what is known about each dimension currently, as well as to propose additional potential future areas to broaden understanding. Specific key takeaways include: (I) understanding risk exposure in young people with IBD requires consideration of disease-specific, demographic, and sociocultural factors; (II) protective and promotive factors and processes for these young people span individual, familial, peer, school, and community levels; and (III) desired outcomes encompass both the absence of negative and the presence of positive indicators. Conclusions: A multisystemic approach to the study of resilience in young people with IBD may not only clarify current gaps in the field, but also allow for additional future considerations to best understand how and for whom outcomes characterized as resilient may occur in this population.

Naming hypoglycemia: a narrative tool for young people with type 1 diabetes and their families.

Objective: Hypoglycemia constitutes a communication barrier between youth with type 1 diabetes, their family members and health professionals. A narrative tool may contribute to a more effective communication. Methods: Semi-structured interviews with six open-ended questions using narrative techniques collect and analyze (thematic and comparative analysis) different ways of "naming" the lived experience of hypoglycemia. Results: 103 participants, 40 with type 1 Diabetes aged 10-18 years (17 female), 63 relatives (40 female). Group 1 (G1), 10-14 years old (n = 21), Group 2 (G2), 15-18 years old (n = 19), Group 3 (G3) relatives, 30-59 years old. G3 was divided, G3.1: female (n = 42) and G3.2: male (n = 21).G1 and G2 presents greater attention to symptoms. G1 refers a greater need for help, G2 emphasizes autonomy. G2 and G3 describes better the medical protocol. G1 and G2 refer more topics such as "discomfort", "frustration", "obligation", "difficulty in verbalizing", G3 refers to "gilt", "fear" and "responsibility". G3.1 refer more "symptoms", "responsibility", "fault", "incapacity". Conclusions: A narrative tool enhances the singularity of a common experience, proving itself useful to adolescents, relatives, and healthcare professionals. Practice implications: In addition to gathering information that is usually acquired empirically, a narrative tool exposes knowledge gaps and may allow implementing intervention strategies.

Pediatric oncology caregiving as narrative repair: Restor(y)ing disrupted family biographies and damaged moral identities.

Drawing on Arthur Frank's conceptualization of narrative repair, we consider how pediatric oncology nurses restore and re-story the narratives of patients and families whose biographies have been thrown off course by the diagnosis and death of a child from cancer, as well as their own narratives as caregivers. Frank argued that when one's life story is shipwrecked by chronic or life-threatening illness, storytelling is way to reorient one's biography to a new ending, repairing the narrative wreckage created by the illness experience. In this critical narrative study with nine pediatric oncology nurses in Ontario, Canada, we highlight how, through physical, narrative, and moral proximity, nurses become entwined in their patients' and families' illness narratives, and how developing this narrative knowledge provides nurses with opportunities to steer families onto new terrain. As well, we examine how nurses re-story and repair their own identities as "good" caregivers in situations when they are prevented from acting on behalf of their pediatric cancer patients. These findings contribute to literature on illness narratives by considering narrative repair as a relational process enacted as part of pediatric oncology caregiving.

Body-Related Existential Dilemmas During Gender Transition: Research in the Italian Context.

The scientific literature shows that gender transition is effective in improving the general well-being of transgender people. However, so far, little attention has been paid to the actual role of the body concerning the existential dilemma that holds the person hostage during transition. This study investigates the relationship between the body-here considered in its concrete, experienced, imagined, and intersubjective dimensions-and gender identity. Twenty-five transgender people who live in Italy were interviewed to identify interpretive repertoires and identity positionings. Four main repertoires and positionings emerged: 1) Interpretative repertoires on the body in transition, where an enduring influence of gender binarism and biological determinants were observed; 2) Expectations regarding medically induced modifications of the body ranging from self-confidence to uncertainty; 3) Positionings toward medically induced bodily modifications, ranging from enthusiasm to resignation; and 4) Inter- and Intrapersonal positionings, where the other than self was found to act as a self-confirming resource or as a constant unpredictable and potentially threatening source of disconfirmation. Practitioners need to develop a stronger awareness of the different dimensions, meanings, and discourses surrounding bodily experience to more effectively intervene in their clinical practice with transgender people.

Interpersonal curiosity as a tool to foster safe relational spaces: a narrative literature review.

Interpersonal curiosity (IPC), or the desire for information about others, is a core component of human connection, belonging, security, survival, and flourishing. Current research on leveraging IPC is scarce, making it an overlooked mechanism for building safer relational spaces. This narrative literature review attempts to answer the following questions: how can IPC facilitate safe relational spaces? How can this knowledge be made accessible and actionable for readers working in relational fields or public health? Results from the analysis of 23 articles indicate that IPC can manifest as either a trait or a state. At best, IPC can be a powerful tool for connection. At worst, IPC can lead to non-prosocial behaviors and relational disruptions. Suggestions are provided to harness the potential of IPC to foster quality connection and safer relational spaces.

Locked-in syndrome: A qualitative study of a life story.

INTRODUCTION: Locked-in syndrome (LIS) is characterized by tetraplegia, anarthria, paralysis of cranial nerves, and facial musculature, with the preservation of consciousness and cognitive abilities, as well as vertical eye movements and eyelid movements, hearing, and breathing. Three types of LIS are distinguished: classic, incomplete, and total. The aim of the present study was to describe the life history of a person with LIS, as well as the wife's experience and perspective of this life history. METHODS: A qualitative life history study was conducted with two participants: a 54-year-old man diagnosed with LIS and his 50-year-old wife. Data were collected through interviews and autobiographical documents submitted by the participants and analyzed following Braun and Clarke's method of inductive thematic analysis. RESULTS: Five main themes were identified: (1) how to understand and overcome the new situation; (2) the process of care and rehabilitation; (3) communication; (4) writing as a way of helping oneself and others; and (5) personal autonomy and social participation. CONCLUSION: The participants valued the support of their friends and family in the acceptance stage of the new situation, giving special importance to the communication skills and medical attention received after diagnosis.

What is known about adolescent dysmenorrhoea in (and for) community health settings?

Introduction: Dysmenorrhoea affects many adolescents with significant impacts on education and well-being. In the UK, most of the adolescents who seek care (and many never do), will do so through general practice (primary care). Knowing how best to care for adolescents reporting menstrual pain is an area where UK general practitioners would like better guidance and resources. Methods: This mixed-methods narrative synthesis collates community and specialist evidence from 320 papers about adolescent dysmenorrhoea, with a UK general practice community health perspective. Results: We report a narrative summary of symptoms, cause, consequences and treatments for adolescent dysmenorrhoea. We highlight areas of tension or conflicted evidence relevant to primary care alongside areas of uncertainty and research gaps identified through this synthesis with input from lived experience advisers. Discussion: There is little evidence about primary care management of adolescent dysmenorrhoea or specific resources to support shared-decision making in general practice, although there are evidence-based treatments to offer. Primary care encounters also represent potential opportunities to consider whether the possibility of underlying or associated health conditions contributing to symptoms of dysmenorrhoea, but there is little epidemiological evidence about prevalence from within community health settings to inform this. The areas where there is little or uncertain evidence along the care journey for adolescent dysmenorrhoea, including at the interface between experience and expression of symptoms and potential underlying contributory causes warrant further exploration.

Transformational healing: the phenomenology of fulfilment in the face of adversity.

In the last two decades, there has been an explosion of scholarship in the phenomenology of health and illness of great practical significance for clinicians and the allied health professions. 'Healing' has been distinguished from medical 'cure' insofar as it involves a process of existential re-integration even in the face of ongoing illness and incapacity. This article goes further than much existing literature in the field: it examines ways in which illness can trigger for some 'transformational healing'-that is, not simply a return to previous functioning, but positive alterations that open one's life to enhanced fulfilment, authenticity and/or connection. Using philosophical resources and 'pathographies', first-person accounts of illness and healing, we examine six forms, often interconnected, of transformational healing. These involve, in turn: vulnerability, intimacy, resilience, presence, gratitude and transcendence In placing a spotlight on ways in which serious illness, injury and disability can inform positive transformations, we are not minimising the suffering often associated with such conditions. Nonetheless, many individuals experience life-enhancements despite, or even because of, the effects of suffering which can reveal personal strengths, deepened intimacy with others and heightened appreciation of life. The possibility of transformational healing, while far from a universal experience, has personal, philosophical and clinical significance not to be overlooked.

Medical narrative ability and humanistic care ability of Chinese clinical nurses: The mediating role of empathy ability.

AIMS: To investigate the relationship between medical narrative ability and humanistic care ability among Chinese clinical nurses, examining the potential mediating role of empathy. BACKGROUND: In the context of the bio-psychosocial medical model and humanistic nursing care, understanding the core competencies of medical narrative ability, empathy and humanistic care in nursing is crucial. This study explored the mediating role of empathy between medical narrative ability and humanistic care ability. DESIGN: A cross-sectional study. METHODS: The study employed a descriptive, cross-sectional survey design, involving 741 nurses from Wuxi People's Hospital. It assessed nurses' demographic characteristics, medical narrative ability, empathy, and humanistic care ability using an online questionnaire from December 2022 to February 2023. Pearson correlation analysis evaluated variable correlations, and PROCESS v3.3 model 4 was utilised for mediation analysis. The STROBE statement was chosen as the EQUATOR checklist. RESULTS: A positive correlation was found between nurses' medical narrative ability, humanistic care ability and empathy. Empathy partially mediated the relationship between medical narrative ability and humanistic care ability. CONCLUSION: Nurses' medical narrative ability directly and indirectly (via empathy) influences their humanistic care ability. Enhancing nurses' narrative and empathic skills can improve humanistic care, nursing quality and nurse-patient relationships. RELEVANCE TO CLINICAL PRACTICE: Managers should prioritise programmes to improve nurses' storytelling and empathy skills to enhance humanistic care, improving nursing quality and patient relationships. PUBLIC CONTRIBUTION: This study involves clinical nurses as participants and does not involve patients. This study collected data from clinical nurses using an online questionnaire platform in China. The questionnaire consisted of four sections, including demographic information and scales such as Narrative Competence Scale, Caring Ability Inventory and the Jefferson Scale of Empathy-Health Professional. Clear instructions were given to participants on how to complete each scale, and measures were taken to prevent missing or duplicate responses.

Neurovascular coupling methods in healthy individuals using transcranial doppler ultrasonography: A systematic review and consensus agreement.

Neurovascular coupling (NVC) is the perturbation of cerebral blood flow (CBF) to meet varying metabolic demands induced by various levels of neural activity. NVC may be assessed by Transcranial Doppler ultrasonography (TCD), using task activation protocols, but with significant methodological heterogeneity between studies, hindering cross-study comparisons. Therefore, this review aimed to summarise and compare available methods for TCD-based healthy NVC assessments. Medline (Ovid), Scopus, Web of Science, EMBASE (Ovid) and CINAHL were searched using a predefined search strategy (PROSPERO: CRD42019153228), generating 6006 articles. Included studies contained TCD-based assessments of NVC in healthy adults. Study quality was assessed using a checklist, and findings were synthesised narratively. 76 studies (2697 participants) met the review criteria. There was significant heterogeneity in the participant position used (e.g., seated vs supine), in TCD equipment, and vessel insonated (e.g. middle, posterior, and anterior cerebral arteries). Larger, more significant, TCD-based NVC responses typically included a seated position, baseline durations >one-minute, extraneous light control, and implementation of previously validated protocols. In addition, complementary, combined position, vessel insonated and stimulation type protocols were associated with more significant NVC results. Recommendations are detailed here, but further investigation is required in patient populations, for further optimisation of TCD-based NVC assessments.
