BACKGROUND
Prone position is a key component to treat hypoxemia in patients with severe acute respiratory distress syndrome. However, most studies evaluating it exclude patients with brain injuries without any medical evidence.
METHODS
This study includes a systematic review to determine whether brain-injured patients were excluded in studies evaluating prone position on acute respiratory distress syndrome; a prospective study including consecutive brain-injured patients needing prone position. The primary endpoint was the evaluation of cerebral blood flow using transcranial Doppler after prone positioning. Secondary outcomes were intracranial pressure, cerebral perfusion pressure, and tissue oxygen pressure.
RESULTS
From 8,183 citations retrieved, 120 studies were included in the systematic review. Among them, 90 studies excluded brain-injured patients (75%) without any justification, 16 included brain-injured patients (4 randomized, 7 nonrandomized studies, 5 retrospective), and 14 did not retrieve brain-injured data. Eleven patients were included in the authors' pilot study. No reduction of cerebral blood flow surrogates was observed during prone positioning, with diastolic speed values (mean ± SD) ranging from 37.7 ± 16.2 cm/s to 45.2 ± 19.3 cm/s for the right side (P = 0.897) and 39.6 ± 18.2 cm/s to 46.5 ± 21.3 cm/s for the left side (P = 0.569), and pulsatility index ranging from 1.14 ± 0.31 to 1.0 ± 0.32 for the right side (P = 0.145) and 1.14 ± 0.31 to 1.02 ± 0.2 for the left side (P = 0.564) before and during prone position.
CONCLUSIONS
Brain-injured patients are largely excluded from studies evaluating prone position in acute respiratory distress syndrome. However, cerebral blood flow seems not to be altered considering increasing of mean arterial pressure during the session. Systematic exclusion of brain-injured patients appears to be unfounded, and prone position, while at risk in brain-injured patients, should be evaluated on these patients to review recommendations, considering close monitoring of neurologic and hemodynamic parameters.

In this systematic review and meta-analysis, a normative dataset is generated from the published literature on the kynurenine pathway in control participants extracted from case-control and methodological validation studies. Study characteristics were mapped, and studies were evaluated in terms of analytical rigour and methodological validation. Meta-analyses of variance between types of instruments, sample matrices and metabolites were conducted. Regression analyses were applied to determine the relationship between metabolite, sample matrix, biological sex, participant age and study age. The grand mean concentrations of tryptophan in the serum and plasma were 60.52 ± 15.38 μM and 51.45 ± 10.47 μM, respectively. The grand mean concentrations of kynurenine in the serum and plasma were 1.96 ± 0.51 μM and 1.82 ± 0.54 μM, respectively. Regional differences in metabolite concentrations were observed across America, Asia, Australia, Europe and the Middle East. Of the total variance within the data, mode of detection (MOD) accounted for up to 2.96%, sample matrix up to 3.23%, and their interaction explained up to 1.53%; the latter of which was determined to be negligible. This review was intended to inform future empirical research and method development studies and successfully synthesised pilot data. The pilot data reported in this study will inform future precision medicine initiatives aimed at targeting the kynurenine pathway by improving the availability and quality of normative data.

Review
: This review focuses on reviewing studies from the literature regarding the effects of deep margin elevation on the surrounding periodontium. : A review of the literature was carried out using the following online databases: Embase, The Cochrane Library, MEDLINE-PubMed and Google Scholar. Our search was limited to articles from 2010 to 2023. The search terms consisted of keywords and MeSH terms, which were 'deep margin elevation', 'coronal margin relocation', 'periodontium' and 'periodontal tissues'. The literature was searched thoroughly by two reviewers. Initially, the titles of the articles were extracted. After removing irrelevant and duplicate articles, abstracts were assessed for relevant articles. Finally, the reviewers analyzed full-text articles. A total of twelve articles, including one randomized clinical trial, three systematic reviews, two prospective cohort, three case series, one a clinical study, one pilot study and one a retrospective study, were selected and analyzed. The review suggests potential benefits of Deep Margin Elevation (DME) over surgical crown lengthening due to reduced invasiveness, yet conclusive effects on periodontal tissue remain unclear, warranting further studies on clinical parameters and inflammatory biomarkers.

UNLABELLED
The RICO study indicated that most patients would like to receive information regarding their fracture risk but that only a small majority have actually received it. Patients globally preferred a visual presentation of fracture risk and were interested in an online tool showing the risk.
PURPOSE
The aim of the Risk Communication in Osteoporosis (RICO) study was to assess patients' preferences regarding fracture risk communication.
METHODS
To assess patients' preferences for fracture risk communication, structured interviews with women with osteoporosis or who were at risk for fracture were conducted in 11 sites around the world, namely in Argentina, Belgium, Canada at Hamilton and with participants from the Osteoporosis Canada Canadian Osteoporosis Patient Network (COPN), Japan, Mexico, Spain, the Netherlands, the UK, and the USA in California and Washington state. The interviews used to collect data were designed on the basis of a systematic review and a qualitative pilot study involving 26 participants at risk of fracture.
RESULTS
A total of 332 women (mean age 67.5 ± 8.0 years, 48% with a history of fracture) were included in the study. Although the participants considered it important to receive information about their fracture risk (mean importance of 6.2 ± 1.4 on a 7-point Likert scale), only 56% (i.e. 185/332) had already received such information. Globally, participants preferred a visual presentation with a traffic-light type of coloured graph of their FRAX® fracture risk probability, compared to a verbal or written presentation. Almost all participants considered it important to discuss their fracture risk and the consequences of fractures with their healthcare professionals in addition to receiving information in a printed format or access to an online website showing their fracture risk.
CONCLUSIONS
There is a significant communication gap between healthcare professionals and patients when discussing osteoporosis fracture risk. The RICO study provides insight into preferred approaches to rectify this communication gap.

BACKGROUND AND AIMS
Irritable bowel syndrome (IBS) is a prevalent disorder with a complex and heterogeneous physiopathology, including a dysregulation of gut-brain axis. Treatment for IBS is targeted to the predominant symptom and requires a multidisciplinary approach. This review aims to evaluate the efficacy and safety of sacral nerve stimulation in non-constipated IBS patients Methods: A literature search was carried out on MEDLINE, The Cochrane Central Register of Controlled Trials (CENTRAL) and Web of Science databases for all relevant articles. Quality of included papers was assessed using standardized guidelines Results: Of 129 initial citations, 7 articles met our predefined inclusion criteria, including five randomized trials, a pilot study and a descriptive follow-up study. Five of 7 studies reported a positive effect of sacral nerve stimulation on symptoms and quality of life improvement in non-constipated IBS patients. No study reported serious adverse events.
CONCLUSIONS
Despite initial promising results of sacral nerve stimulation in non-constipated IBS patients, studies with larger sample sizes and longer follow-up are required.

OBJECTIVES
Family and friend caregivers often feel overwhelmed by and ill-prepared for their responsibilities. Many feel helpless living with uncertainty about the outcome of the patient's illness, which leads to existential distress. Supportive care interventions that address existential distress by promoting meaning and purpose buffer the negative effects of caregiver burden and promote resilience and growth. The purpose of this scoping review is to describe the depth and breadth of available interventions targeting caregiver existential distress.
METHODS
We followed the Joanna Briggs Institute's scoping review methods and applied the Preferred Reporting Items for Systematic Reviews and Meta-Analyses Extension checklist. SCOPUS, Ovid MEDLINE and PsycINFO databases were searched for interventions that targeted existential distress by promoting meaning-making, spiritual well-being, post-traumatic growth and/or benefit finding for caregivers of seriously ill adult patients.
RESULTS
We screened 1377 titles/abstracts and 42 full-text articles. Thirty-one articles (28 unique studies) met inclusion criteria. Most interventions were designed for caregivers supporting patients with cancer (n=14) or patients receiving palliative care (n=9). Promising interventions included Meaning-Centered Psychotherapy for Cancer Caregivers, Meaning-Based Intervention for Patients and their Partners, Legacy Intervention for Family Enactment, Family Participatory Dignity Therapy and Existential Behavioural Therapy. More than half of the studies (n=20, 64%) were in the feasibility/acceptability/pilot stage of intervention testing.
CONCLUSION
Large randomised controlled trials with more diverse samples of caregivers are needed. Future research should explore the impact of delivering meaning-making interventions to caregivers throughout the illness trajectory. Developing strategies for scaling up and conducting cost analyses will narrow the research and practice gap for meaning-making interventions.

Meta-Analysis
Clinico-characteristics of patients which correlated with preferable treatment outcomes in immunotherapy for advanced hepatocellular carcinoma: a systematic review and meta-analysis.
BACKGROUND AND AIMS
Hepatocellular carcinoma (HCC) is the third-most lethal malignant tumor worldwide. The rapid development of immunotherapy utilizing immune checkpoint inhibitors for advanced HCC patients has been witnessed in recent years, along with numerous randomized clinical trials demonstrating the survival benefits for these individuals. This systematic review and meta-analysis aimed to identify specific clinico-pathological characteristics of advanced HCC patients that may lead to preferable responses to immunotherapy in terms of overall survival (OS), progression-free survival (PFS), and objective response rate (ORR).
METHODS
The included clinical trials were retrieved from PubMed, Embase, the Cochrane library, and the Web of Science databases published in English between 1 January 2002 and 20 October 2022. A systematic review and meta-analysis for first-line and second-line phase II/III studies were conducted on immunotherapy for patients with advanced HCC by using OS as the primary outcome measure, and PFS and ORR as the secondary outcome measures to obtain clinico-pathological characteristics of patients which might be preferable responses to programmed death-1 (PD-1) and programmed cell death-Ligand 1 (PD-L1) inhibitors. Toxicity and specific treatment-related adverse events (TRAEs) were also determined.
RESULTS
After screening 1392 relevant studies, 12 studies were included in this systematic review and meta-analysis to include 5948 patients. Based on the analysis of interaction, the difference in OS after first-line immunotherapy between the subgroups of viral hepatitis [hazard ratio (HR)=0.73 vs 0.87, P for interaction=0.02] and macrovascular invasion and/or extrahepatic spread (HR=0.73 vs 0.89, P for interaction=0.02) were significant. The difference in PFS between the subgroups of viral hepatitis was highly significant (pooled HR=0.55 vs 0.81, P for interaction=0.007). After second-line immunotherapy, the difference in ORR between the subgroups of Barcelona Clinic Liver Cancer was significant (pooled ES=0.12 vs 0.23, P for interaction=0.04). Compared with PD-L1 inhibitors, PD-1 inhibitors may have a higher probability to cause TRAEs. Diarrhea, increased aspartate aminotransferase, and hypertension were the top three TRAEs.
CONCLUSIONS
This systematic review and meta-analysis represents the first pilot study aimed at identifying crucial clinico-pathological characteristics of patients with advanced HCC that may predict favorable treatment outcomes in terms of OS, PFS, and ORR to immunotherapy. Findings suggest that patients with viral hepatitis positivity (especially hepatitis B virus) and macrovascular invasion and/or extrahepatic spread may benefit more in OS when treated with PD-1/PD-L1 immune checkpoint inhibitors.

OBJECTIVES
The aim of the systematic review was to compare studies on implant-supported two-unit cantilever crowns with two adjacent implant-supported crowns in the anterior region. The second aim was to assess in a 10-year prospective comparative pilot study, hard and soft peri-implant tissue changes in patients with a missing central and adjacent lateral upper incisor, treated with either an implant-supported two-unit cantilever crown or two single implant-supported crowns.
MATERIALS AND METHODS
Medline, Embase, and the Cochrane Central Register of Controlled Trials were searched (last search March 1, 2023). Inclusion criteria were studies reporting outcomes of two missing adjacent teeth in the esthetic region and treated with a single implant-supported two-unit cantilever fixed dental prosthesis, or with two solitary implant-supported crowns. Outcome measures assessed included implant survival (primary), changes in marginal bone and gingiva level, restoration survival, subjective and objective esthetic scores, papilla volume, mid-facial marginal mucosa level, probing depth, bleeding on probing, and biological and technical complications with ≥1-year follow-up. In addition, in a 10-year pilot study, the same outcome measures were assessed of five patients with a single implant-supported two-unit cantilever crown and compared with five patients with two adjacent single implant-supported crowns in the esthetic zone.
RESULTS
Nine articles with 11 study groups were found eligible for data extraction. Meta-analyses of implant survival rates were 96.9% (mean follow-up 3.4 ± 1.4 years) for the implant-cantilever treatment and 97.6% (mean follow-up 3.0 ± 1.8 years) for the adjacent implants treatment (p = .79). In the 10-year comparative pilot study, no clinically relevant changes in hard and soft peri-implant tissue levels occurred in both groups. Patient satisfaction was also high in both groups.
CONCLUSION
Single implant-supported two-unit crowns can be a viable alternative to the placement of two adjacent single implant crowns in the esthetic zone.

Review
INTRODUCTION
Climate change poses enormous threats to humanity and much of life on earth. Many of the behavioral patterns that drive climate change also contribute to the epidemics of obesity, diabetes, and cardiovascular disease.
OBJECTIVES
The primary objective of this study was to compile and categorize the literature on interventions aimed at modifying individual behaviors to promote both personal health and environmental sustainability. Secondary objectives were to help define the emerging field of behavioral eco-wellness and to discuss future directions, including the need for assessment tools and analytic strategies.
METHODS
A scoping review was conducted to locate, categorize, and interpret current scientific studies of interventions aimed at changing individual behaviors to promote both personal health and environmental sustainability.
RESULTS
Other than a pilot study that this team previously conducted, nothing was found that strictly fit the inclusion criteria. However, we did find 16 relevant studies that fit neatly within 4 broad topical areas: active transportation, dietary intake, indoor air quality, and green space immersion.
DISCUSSION
While this systematic scoping review found little meeting original criteria, we did find that 4 separate fields of study are converging on a scientific area that we are calling behavioral eco-wellness, defined as the simultaneous pursuit of both personal health and environmental sustainability. The emerging field could provide a conceptual framework and methodological toolkit for those seeking to enhance sustainability while supporting health behaviors, including dietary intake. This, in turn, could help to inform and motivate the urgent action needed to confront both climate change and the epidemics of obesity, diabetes, and cardiovascular disease.

Medical students commonly exhibit mental health issues. Despite the availability of professionals on medical campuses, seeking help continues to be a challenge for some students. Our review aimed to identify the barriers medical students face when seeking professional mental healthcare. A Medical Subject Headings (MeSH) search was created for articles using PubMed, Embase, and PsychINFO databases to identify articles specifically about medical students and their barriers to professional mental healthcare. Inclusion criteria included articles in which barriers to mental healthcare were either the primary variable or one of multiple study results. No date limits were imposed. Reviews, pilot projects, or articles that did not address barriers to mental healthcare faced by medical students or focused on veterinary or dental students were excluded. A total of 454 articles were identified and screened by title/abstract and then full text. Data were extracted from 33 articles using an independent framework. Barriers identified were compiled and reported. From a total of 33 articles, the most identified barriers were fear of negative effect on residency/career opportunities, fear of confidentiality breach, stigma and fear of shaming from peers, lack of perceived seriousness/normalization of symptoms, lack of time, and fear of documentation on academic record. Students also preferred to seek care outside of their institution from fear of their provider being an academic preceptor. Many of the barriers to mental healthcare faced by medical students relate to a fear of academic and career reprisal, and fear of confidentiality breach. It appears that despite recent efforts to decrease stigma surrounding mental illness, many medical students struggle to seek appropriate support. Access to mental healthcare can be improved by increasing transparency regarding what information will be displayed on academic records, dispelling common myths about mental healthcare, and increasing awareness about resources available for medical students.
