This study aimed to gain a better understanding of nursing/midwifery students' perspectives on a pedagogy of caring and online learning during the COVID-19 pandemic. In addition, it aimed to determine if the COVID-19 pandemic impacted students' perceptions and experience of online learning and students' desire to enter the nursing/midwifery workforce.
Mixed methods.
A multi-centre cross-sectional survey of Australian nursing and midwifery students was undertaken to explore students’ experience of learning during the COVID-19 pandemic.
There are several key findings from this study that may be relevant for the future delivery of undergraduate health education, students transitioning to practice and healthcare workforce retention. The study found that although students were somewhat satisfied with online learning during COVID-19, students reported significant issues with knowledge/skill acquisition and barriers to the learning process. The students reported feeling less prepared for practice and identified how clinical staff were unable to provide additional guidance and support due to increased workloads and stress. The textual responses of participants highlighted that connection/disconnection, empathy and engagement/disengagement had an impact on learning during COVID-19.
Connection, engagement and isolation were key factors that impacted nursing students’ online learning experiences. In addition, graduates entering the workforce felt less prepared for entry into practice due to changes in education delivery during COVID-19 that they perceived impacted their level of clinical skills, confidence and ability to practice as new graduate nurses/midwives.
Not applicable.
Attention must be given to the transition of new graduate nurses and midwives whose education was impacted by pandemic restrictions, to support their professional career development and to ensure retention of future healthcare workforce. Connection, engagement and isolation were key factors that impacted nursing students' online learning experiences. Educators should consider how connection and engagement can be actively embedded in the online learning environment.

BackgroundWork on long COVID-19 has mainly focused on clinical care in hospitals. Thermal spa therapies represent a therapeutic offer outside of health care institutions that are nationally or even internationally attractive. Unlike local care (hospital care, general medicine, para-medical care), their integration in the care pathways of long COVID-19 patients seems little studied. The aim of this article is to determine what place french thermal spa therapies can take in the care pathway of long COVID-19 patients.
MethodsBased on the case of France, we carry out a geographic mapping analysis of the potential care pathways for long COVID-19 patients by cross-referencing, over the period 2020–2022, the available official data on COVID-19 contamination, hospitalisations in intensive care units and the national offer of spa treatments. This first analysis allows us, by using the method for evaluating the attractiveness of an area defined by David Huff, to evaluate the accessibility of each French department to thermal spas.
ResultsUsing dynamic geographical mapping, this study describes two essential criteria for the integration of the thermal spa therapies offer in the care pathways of long COVID-19 patients (attractiveness of spa areas and accessibility to thermal spas) and three fundamental elements for the success of these pathways (continuity of the care pathways; clinical collaborations; adaptation of the financing modalities to each patient). Using a spatial attractiveness method, we make this type of geographical analysis more dynamic by showing the extent to which a thermal spa is accessible to long COVID-19 patients.
ConclusionBased on the example of the French spa offer, this study makes it possible to place the care pathways of long COVID-19 patients in a wider area (at least national), rather than limiting them to clinical and local management in a hospital setting. The identification and operationalization of two geographical criteria for integrating a type of treatment such as a spa cure into a care pathway contributes to a finer conceptualization of the construction of healthcare pathways.

This study was designed to explore mothers’ perceptions about changes in parenting behavior in the middle of the pandemic COVID 19 period. Based on the convergent mixed-method design and Parental Stress model, we illustrated these changes by taking into account the impact of the pandemic perceived by mothers and the resources they had available. Research on parenting changes was important in the Romanian context because, in that challenging period, there were no regulations to safeguard parents, especially single parents as mothers. Mothers experienced increased levels of stress, some of them having to leave their jobs to stay at home with their children. Other mothers needed to work from home and in the meantime to take care of their children. In this context we wanted to illustrate the possible changes that occurred in their parenting behavior during the pandemic period. Results from the quantitative survey showed that there is a moderate correlation between the negative impact felt by mothers and the negative changes in their parenting behavior, and this correlation was diminished by a series of resources such as: social support, parenting alliance, or high income. Qualitative data provided better understanding of mothers’ parenting behavior by showing that mothers shared both positive and negative experiences during the pandemic, regardless of the general trend mentioned. As shown by the quantitative data, the qualitative data also showed that mothers who felt more strongly the impact of the pandemic reported more negative changes in their parenting behavior. The positive changes most frequently stated involved expressing affection and communicating more often on various topics, carrying out leisure activities or activities meant to help with the personal development of the child, and involving children in domestic activities. Mothers mostly described negative aspects such as too much involvement in school life, increased control and surveillance of children, especially when it comes to school related activities and to the time children were allowed to spend on their digital devices. These changes led to conflicts and sometimes, mothers resorted to discipline practices. In addition to the resources identified in quantitative research, mothers with higher education and medium–high income also turned to specialized resources (psychologists, online courses, support groups) in order to manage conflicts, them being able to see the challenges of the pandemic as an opportunity to develop and improve the relationship with their children.by Alvaro Torres-Huerta, Katelyn Ruley-Haase, Theodore Reed, Antonia Boger-May, Derek Rubadeux, Lauren Mayer, Arpitha Mysore Rajashekara, Morgan Hiller, Madeleine Frech, Connor Roncagli, Cameron Pedersen, Mary Catherine Camacho, Lauren Hollmer, Lauren English, Grace Kane, David L.

Inflammatory bowel diseases (IBD) result from uncontrolled inflammation in the intestinal mucosa leading to damage and loss of function. Both innate and adaptive immunity contribute to the inflammation of IBD and innate and adaptive immune cells reciprocally activate each other in a forward feedback loop. In order to better understand innate immune contributions to IBD, we developed a model of spontaneous 100% penetrant, early onset colitis that occurs in the absence of adaptive immunity by crossing villin-TNFAIP3 mice to RAG1-/- mice (TRAG mice). This model is driven by microbes and features increased levels of innate lymphoid cells in the intestinal mucosa. To investigate the role of type 3 innate lymphoid cells (ILC3) in the innate colitis of TRAG mice, we crossed them to retinoid orphan receptor gamma t deficient (Rorγt-/-) mice. Rorγt-/- x TRAG mice exhibited markedly reduced eosinophilia in the colonic mucosa, but colitis persisted in these mice. Colitis in Rorγt-/- x TRAG mice was characterized by increased infiltration of the intestinal mucosa by neutrophils, inflammatory monocytes, macrophages and other innate cells. RNA and cellular profiles of Rorγt-/- x TRAG mice were consistent with a lack of ILC3 and ILC3 derived cytokines, reduced antimicrobial factors, increased activation oof epithelial repair processes and reduced activation of epithelial cell STAT3. The colitis in Rorγt-/- x TRAG mice was ameliorated by antibiotic treatment indicating that microbes contribute to the ILC3-independent colitis of these mice. Together, these gene expression and cell signaling signatures reflect the double-edged sword of ILC3 in the intestine, inducing both proinflammatory and antimicrobial protective responses. Thus, Rorγt promotes eosinophilia but Rorγt and Rorγt-dependent ILC3 are dispensable for the innate colitis in TRAG mice.Peritoneal dialysis (PD) allows patients increased autonomy and flexibility; however, both infectious and non-infectious complications may lead to technique failure, which shortens treatment longevity. Maintaining patients on PD remains a major challenge for nephrologists. This study aims to describe nephrologists’ perspectives on technique survival in PD.
Qualitative semistructured interview study. Transcripts were thematically analysed.
30 nephrologists across 11 countries including Australia, the USA, the UK, Hong Kong, Canada, Singapore, Japan, New Zealand, Thailand, Colombia and Uruguay were interviewed from April 2017 to November 2019.
We identified four themes: defining patient suitability (confidence in capacity for self-management, ensuring clinical stability and expected resilience), building endurance (facilitating access to practical support, improving mental well-being, optimising quality of care and training to reduce risk of complications), establishing rapport through effective communications (managing expectations to enhance trust, individualising care and harnessing a multidisciplinary approach) and confronting fear and acknowledging barriers to haemodialysis (preventing crash landing to haemodialysis, facing concerns of losing independence and positive framing of haemodialysis).
Nephrologists reported that technique survival in PD is influenced by patients’ medical circumstances, psychological motivation and positively influenced by the education and support provided by treating clinicians and families. Strategies to enhance patients’ knowledge on PD and communication with patients about technique survival in PD are needed to build trust, set patient expectations of treatment and improve the process of transition off PD.
To systematically explore the clinical supervision (CS) experience for nurses transitioning to advanced practice.
A qualitative systematic review using Joanna Briggs Institute meta-aggregation following an a priori protocol published on PROSPERO (CRD42023426658).
Qualitative studies obtained from Medline, CINAHL, PsycINFO, Scopus, Emcare and ERIC databases and ProQuest dissertations and theses for peer-reviewed, published and unpublished studies from inception to July 2023.
Two authors conducted data screening and abstraction. Quality was appraised using the Critical Appraisal Skills Programme tool and reporting followed the Enhancing Transparency in Reporting the Synthesis of Qualitative Research checklist for systematic reviews.
Sixteen studies contributed to five synthesized findings: CS that is beneficial requires structure and commitment, trusting relationships are foundational for learning, lifting burdens and preventing burnout, learning through reflection, critical thinking and feedback and barriers to CS.
This review provides a meaningful exploration of CS to support nurses transitioning to advanced practice. Well-structured supervision offers a safe space to share work-related concerns and develop an advanced practitioner identity. Sharing experiences helps alleviate work-related burdens and reduce professional isolation and burnout.
Peer-support networks are vital for successful transition to advanced practice.
This review highlighted the impact of effective supervisory relationships in forming professional identity and possible links with nursing retention.

To highlight the value of utilizing the Listening Guide methodology for nursing research and provide an exemplar applying this methodology to explore a novel concept in an underrepresented group—inner strength in persons newly diagnosed with mild cognitive impairment along with their care partners.
Methodology discussion paper.
The exemplar study used the Listening Guide methods for data elicitation and analysis. Methods included adaptations for the study population and novice qualitative researchers.
The Listening Guide methodology with adaptations enabled the research team to centre the voices of persons living with mild cognitive impairment, highlight an abstract phenomenon and attend to the influences of the sociopolitical context. Further, this methodology helped address common challenges emerging qualitative researchers encounter, including understanding methods of application, engaging reflexively and immersing in the data.
The Listening Guide is a voice-centred qualitative methodology that is well suited to foreground the experiences of groups underrepresented in research and explore emerging phenomena.
Nurses are central to striving for health equity. The Listening Guide methodology offers a valuable and accessible research tool to understand the experiences and needs of underrepresented groups and shape healthcare in response.
The Listening Guide methodology can be broadly applied to research with persons with mild cognitive impairment, and other underrepresented groups, to explore other phenomena beyond inner strength and move the science forward in representing the perspectives of groups underrepresented by research.
Persons living with cognitive impairment and their care partners participated in study conceptualization, interview guide development, methods development and dissemination plans.
To explore general nurses' experiences of modifying and implementing contextually suitable Safewards interventions into medical and surgical hospital wards.
Qualitative action research was used working with nurses as co-researchers.
Pre-implementation focus groups were conducted in April 2022 to understand and explore the current strategies nurses utilized to avert, respond to or decrease violence. Following this, two Safewards interventions were modified by the nurses on the wards. Post-implementation focus groups were conducted in October 2022, to explore the nurses' experience of implementing Safewards interventions and the effect on their nursing practice. Data were analysed using Braun and Clarke's framework for thematic analysis.
Three themes emerged from the analysis of the pre-implementation focus groups that reflected the type of violence experienced by these nurses and the context within which they occurred: ‘the space is hectic’; ‘it can feel like a battlefield’; and ‘the aftermath’. These themes encompass the nurses' experience of violence from patients and their visitors. Following the implementation of two modified Safewards interventions, the analysis of the focus groups reflected a change in nursing skills to avert or respond to violence: ‘Safewards in action’; ‘empathy and self-reflection’; and ‘moving forward’.
Safewards interventions can be successfully modified and used in general hospital wards and influence nursing practice to manage patient and visitor violence.
In the interests of safety, successful interventions to reduce violence towards general hospital nurses should be a priority for managers and healthcare organizations. Averting, mitigating and managing violence can decrease the negative professional and personal effect on nurses and ultimately improve well-being, job satisfaction and retention rates. Furthermore, decreasing violence or aggressive incidents leads to a safer patient experience and decreased number of nursing errors ultimately improving patient experiences and outcomes.
Understanding nurses' experiences of violence and working with them to explore and develop contextually relevant solutions increases their capacity to respond to and avert violent incidents. Contextually modified Safewards interventions offer one such solution and potentially has wider implications for healthcare settings beyond the specific wards studied.
This study addressed the implementation of modified Safewards strategies in medical and surgical wards to prevent violence. Three themes emerged from the analysis of the pre-implementation focus groups that reflected the type of violence experienced by these nurses and the context within which they occurred. Following the implementation of two modified Safewards interventions, the post-implementation focus groups reported positive changes to their practices using the modified resources to prevent violence from patients and their visitors. Mental health interventions, such as those used in the Safewards model can be modified and provide a tool kit of interventions that can be used by medical and surgical nurses.
This paper has adhered to the COREQ guidelines.

This paper outlines and discusses the action research approach undertaken to work with general hospital nurses to modify mental health nurses' Safewards interventions into their clinical practice. This paper provides evidence of the ‘real world’ application of Safewards interventions by medical and surgical nurses in general hospital wards. This paper presents qualitative findings based on focus group methods to highlight the narratives of general nurses and their experiences of violence.
To design, develop and validate a new tool, called NEUMOBACT, to evaluate critical care nurses' knowledge and skills in ventilator-associated pneumonia (VAP) and catheter-related bacteraemia (CRB) prevention through simulation scenarios involving central venous catheter (CVC), endotracheal suctioning (ETS) and mechanically ventilated patient care (PC) stations.
Simulation-based training is an excellent way for nurses to learn prevention measures in VAP and CRB.
Descriptive metric study to develop NEUMOBACT and analyse its content and face validity that followed the COSMIN Study Design checklist for patient-reported outcome measurement instruments.
The first version was developed with the content of training modules in use at the time (NEUMOBACT-1). Delphi rounds were used to assess item relevance with experts in VAP and CRB prevention measures, resulting in NEUMOBACT-2. Experts in simulation methods then assessed feasibility, resulting in NEUMOBACT-3. Finally, a pilot test was conducted among 30 intensive care unit (ICU) nurses to assess the applicability of the evaluation tool in clinical practice.
Seven national experts in VAP and CRB prevention and seven national simulation experts participated in the analysis to assess the relevance and feasibility of each item, respectively. After two Delphi rounds with infection experts, four Delphi rounds with simulation experts, and pilot testing with 30 ICU nurses, the NEUMOBACT-FINAL tool consisted of 17, 26 and 21 items, respectively, for CVC, ETS and PC.
NEUMOBACT-FINAL is useful and valid for assessing ICU nurses' knowledge and skills in VAP and CRB prevention, acquired through simulation.
Our validated and clinically tested tool could facilitate the transfer of ICU nurses' knowledge and skills learning in VAP and CRB prevention to critically ill patients, decreasing infection rates and, therefore, improving patient safety.
Experts participated in the Delphi rounds and nurses in the pilot test.

ContextPotentially inappropriate prescribing of medications in older adults, particular those with dementia, can lead to adverse drug events including falls and fractures, worsening cognitive impairment, emergency department visits, and hospitalizations. Educational mailings from health plans to patients and their providers to encourage deprescribing conversations may represent an effective, low-cost, “light touch”, approach to reducing the burden of potentially inappropriate prescription use in older adults with dementia.
ObjectivesThe objective of the Developing a PRogram to Educate and Sensitize Caregivers to Reduce the Inappropriate Prescription Burden in Elderly with Alzheimer’s Disease (D-PRESCRIBE-AD) trial is to evaluate the effect of a health plan based multi-faceted educational outreach intervention to community dwelling patients with dementia who are currently prescribed sedative/hypnotics, antipsychotics, or strong anticholinergics.
MethodsThe D-PRESCRIBE-AD is an open-label pragmatic, prospective randomized controlled trial (RCT) comparing three arms: 1) educational mailing to both the health plan patient and their prescribing physician (patient plus physician arm, n = 4814); 2) educational mailing to prescribing physician only (physician only arm, n = 4814); and 3) usual care (n = 4814) among patients with dementia enrolled in two large United States based health plans. The primary outcome is the absence of any dispensing of the targeted potentially inappropriate prescription during the 6-month study observation period after a 3-month black out period following the mailing. Secondary outcomes include dose-reduction, polypharmacy, healthcare utilization, mortality and therapeutic switching within targeted drug classes.
ConclusionThis large pragmatic RCT will contribute to the evidence base on promoting deprescribing of potentially inappropriate medications among older adults with dementia. If successful, such light touch, inexpensive and highly scalable interventions have the potential to reduce the burden of potentially inappropriate prescribing for patients with dementia.ClinicalTrials.gov Identifier: NCT05147428.
To examine the impact of implementing nurse-led consultations compared to physician-led consultations on the frequency of follow-up contacts within 14 days following an acute infectious consultation.
Monocentric, prospective cohort study.
The study was conducted in a multidisciplinary, capitation-based general practice in Belgium. Through analysis of patient files, the number of follow-up contacts within 14 days after an infection consultation was investigated to determine any difference between physician-led or nurse-led consultations. Secondary outcomes included pharmacological interventions and the prescribing behaviour of medical leave certificates.
A total of 352 consultations were analysed, of which 174 conducted by physicians and 178 by nurses. No significant difference was found in the number of follow-up contacts. However, the probability of a pharmacological intervention by a physician was revealed to be significantly higher. The presence or absence of such pharmacological intervention did not significantly influence the number of follow-up contacts.
This study demonstrates that nurses can be safely and efficiently utilized in acute infection care within a general practice setting. Although these results are promising, more extensive research is needed which incorporates the experiences of patients and healthcare providers. Furthermore, it is advisable to consider the experience and education of the nurses and incorporate them into the analyses.
This study addressed the high workload on general practitioners by researching a task shift in the acute infectious, primary health care. The results demonstrate the feasibility of this task shift, which may have an impact on primary health care professionals (whose workload may be reorganized), as well as on patients for whom primary care may become more accessible.
This study includes direct patient data from people who presented themselves with acute infectious complaints in a primary healthcare practice.
To describe the implementation of a trauma-informed model of care in the Post COVID Respiratory Clinic of a large tertiary referral centre in NSW.
Discussion paper.
Evidence gathered from a literature search (2008–2022) was used to develop a framework for management of patients presenting to this Post COVID Respiratory Clinic. This paper outlines the personal reflections of the clinic staff as they developed and implemented this framework. Ethical approval was obtained to report the data collected from patient reviews.
The literature highlights the high prevalence of trauma in patients following COVID-19 infection, as well as the larger population both during and after the pandemic. This experience of trauma was observed in patients seen within the clinic, indicating a need for specialized care. In response, a trauma-informed model of care was implemented.
Reconceptualizing COVID-19 as a ‘collective trauma’ can help healthcare workers understand the needs of post-COVID patients and enable them to respond empathetically. A trauma-informed model is complementary to this cohort as it specifically addresses vulnerable populations, many of whom have been further marginalized by the pandemic.
Frontline healthcare workers, particularly nurses, are well positioned to implement trauma-informed care due to their high-level of patient contact. Adequate allocation of resources and investment in staff is essential to ensure such care can be provided.
The COVID-19 pandemic has led to adverse physical and mental health outcomes for many. Trauma-informed care is a way to promote reengagement with the healthcare system in this group. Post COVID patients globally may benefit from this approach, as it aims to build trust and independence.
Feedback was sought from a patient representative to ensure this paper adequately reflected the experience of the post-COVID patient.
To evaluate a nurse-led model of supportive care in a COPD outpatient service from patient and caregiver perspectives.
Case study methodology.
Data were collected from semi-structured interviews with patients (n = 12) and caregivers (n = 7) conducted between April 2020 and September 2022. A purposive sampling strategy was used. Interviews were transcribed verbatim and analysed using content analysis with an inductive approach. COREQ guidelines informed reporting of this study.
Eight categories were identified from the data evaluating of the model of care relating to the most helpful aspects of COPD supportive care and suggested improvements to the model of care. The categories were: guidance with managing symptoms; participating in advance care planning; home visiting; expert advice; continuity and trust; caring; caregiver support and improvements to the model of care.
In a nurse-led model of COPD supportive care, what patients and caregivers valued most was expert advice and guidance with symptom management, flexible home visiting, participation in advance care planning, caring and continuity within an ongoing trusted therapeutic relationship. Understanding what patients and caregivers value most is essential in designing and delivering models of care that meet the needs of patients living with chronic, life-limiting illness.
Nurses can lead effective models of supportive care that offer valuable support to patients living with COPD and their caregivers.

BackgroundPlatelets (PLTS) and fresh frozen plasma (FFP) are often transfused in cardiac surgery patients for perioperative bleeding. Their relative effectiveness is unknown.
MethodsWe conducted an entropy-weighted retrospective cohort study using the Australian and New Zealand Society of Cardiac and Thoracic Surgeons National Cardiac Surgery Database. All adults undergoing cardiac surgery between 2005–2021 across 58 sites were included. The primary outcome was operative mortality.
ResultsOf 174,796 eligible patients, 15,360 (8.79%) received PLTS in the absence of FFP and 6,189 (3.54%) patients received FFP in the absence of PLTS. The median cumulative dose was 1 unit of pooled platelets (IQR 1 to 3) and 2 units of FFP (IQR 0 to 4) respectively. After entropy weighting to achieve balanced cohorts, FFP was associated with increased perioperative (Risk Ratio [RR], 1.63; 95% Confidence Interval [CI], 1.40 to 1.91; P Conclusion
In perioperative bleeding in cardiac surgery patient, platelets are associated with a relative mortality benefit over FFP. This information can be used by clinicians in their choice of procoagulant therapy in this setting.
To explore how emerging adult-aged women self-manage their sexual and reproductive health and to generate a grounded theory of these self-management processes.
Grounded theory methods using a constructivist approach.
Between September 2019 and September 2020, 18‑ to 25-years-old women (n = 13) were recruited from a 4-year university, a 2-year community college, and neighbourhoods surrounding the institutions of higher education. Individual interviews were transcribed verbatim and qualitatively analysed using a constant comparative method and inductive coding.
The theory purports that core processes of sexual and reproductive health self-management used by the women in this study included both passive and (re)active processes. These processes expanded upon and/or maintained the women's accessible sexual and reproductive health knowledge, behaviour and beliefs, defined as the sexual and reproductive health repertoire. The processes appeared to be cyclical and were often initiated by a catalysing event or catalyst and resulted in conversations with confidantes, or trusted individuals. A catalyst was either resolved or normalized by expanding or maintaining the sexual and reproductive health repertoire.
The resulting theory, EMeRGE Theory, offers insight into the complex and cyclical processes emerging adult-aged women use to simultaneously develop and adapt their foundational sexual and reproductive health knowledge, behaviours and beliefs.
This explication of emerging adult-aged women's sexual and reproductive health self-management processes can be used by nurses and nurse researchers to better address this population's unique health needs.
The EMeRGE Theory provides valuable guidance for future exploratory and intervention research aimed at improving the health and well-being of emerging adult-aged women.

Central retinal artery occlusion (CRAO; retinal stroke or eye stroke) is an under-recognized, disabling form of acute ischemic stroke which causes severe visual loss in one eye. The classical risk factor for CRAO is ipsilateral carotid stenosis; however, nearly half of patients with CRAO do not have high-grade carotid stenosis, suggesting that other cardiovascular risk factors may exist for CRAO. Specifically, prior studies have suggested that cardioembolism, driven by underlying atrial fibrillation, may predispose patients to CRAO. We describe the design of an observational, population-based study in this protocol. We evaluate two specific objectives: 1) To determine if atrial fibrillation is an independent risk factor for CRAO after adjusting for medical and cardiovascular risk; 2) To determine if use of oral anticoagulation can modify the risk of CRAO for patients with atrial fibrillation. This protocol lays out our strategy for cohort definition, case and control definition, comorbidity ascertainment, and statistical methods.by Andrea Peloso, Stéphanie Lacotte, Quentin Gex, Florence Slits, Beat Moeckli, Graziano Oldani, Matthieu Tihy, Aurélie Hautefort, Brenda Kwak, Laura Rubbia-Brandt, Christian Toso
Background and aimsNon-alcoholic fatty liver disease (NAFLD) is one of the leading cause of hepatocellular carcinoma (HCC). This association is supported by the translocation of bacteria products into the portal system, which acts on the liver through the gut-liver axis. We hypothesize that portosystemic shunting can disrupt this relationship, and prevent NAFLD-associated HCC.
MethodsHCC carcinogenesis was tested in C57BL/6 mice fed a high-fat high-sucrose diet (HFD) and injected with diethylnitrosamine (DEN) at two weeks of age, and in double transgenic LAP-tTA and TRE-MYC (LAP-Myc) mice fed a methionine-choline-deficient diet. Portosystemic shunts were established by transposing the spleen to the sub-cutaneous tissue at eight weeks of age.
ResultsSpleen transposition led to a consistent deviation of part of the portal flow and a significant decrease in portal pressure. It was associated with a decrease in the number of HCC in both models. This effect was supported by the presence of less severe liver steatosis after 40 weeks, and lower expression levels of liver fatty acid synthase. Also, shunted mice exhibited lower liver oxygen levels, a key factor in preventing HCC as confirmed by the development of less HCCs in mice with hepatic artery ligation.
ConclusionsThe present data show that portosystemic shunting prevents NAFLD-associated HCC, utilizing two independent mouse models. This effect is supported by the development of less steatosis, and a restored liver oxygen level. Portal pressure modulation and shunting deserve further exploration as potential prevention/treatment options for NAFLD and HCC.

BackgroundNutrition affects both physical and mental health but evidence is mixed regarding potential associations between anxiety and diet, particularly dairy consumption. We conducted a systematic literature review (SLR) of dairy consumption and/or various dietary patterns and risk of anxiety.
MethodsLiterature searches were conducted in PubMed and Embase. All study designs except case reports, small case series, and SLRs were considered for inclusion. Reference lists of previously published SLRs were reviewed for any relevant additional studies. Studies of populations without dairy sensitivities exploring the association between dietary patterns and/or dairy consumption and anxiety published through May 2022 were identified using predefined eligibility criteria. Study quality was determined using the Academy of Nutrition and Dietetics Quality Criteria Checklist.
ResultsFor this SLR, 132 studies were included; 80 were cross-sectional. Studies examined different dietary patterns (e.g., Mediterranean, gluten-free) and anxiety using various anxiety scales, with 19 studies specifically reporting on whole dairy consumption and anxiety. Dairy consumption was significantly associated with a lower risk of anxiety in 7 studies, while the remaining 12 studies showed no significant associations. Evidence was mixed for the association between various dietary patterns and anxiety, but more studies observed a lower risk of anxiety with greater adherence to “healthy” diets (e.g., Mediterranean, diet quality score, vegetarian/vegan) than a higher risk. Notable heterogeneity in study populations, time periods, geographical locations, dietary assessment methods, and anxiety scales was observed.
ConclusionsThe results of this SLR suggest a potential link between diet including diary consumption and anxiety, but future studies, especially with longitudinal designs that measure diet and anxiety at several timepoints and comprehensively adjust for confounders, are needed to fully understand the relationship between diet and anxiety.
