BACKGROUND
Diabetic foot ulcers (DFUs) are common complications of uncontrolled diabetes mellitus that can result in infection and amputation of the lower extremities. This study compared the benefits and risks of hyperbaric oxygen therapy with those of other DFU treatments, based on the Wagner grading system.
METHODS
Systematic searches for randomly controlled trials using hyperbaric oxygen therapy for DFUs were performed using PubMed, the Cochrane Library, and Embase. Data regarding demographics, wound healing, minor and major amputations, operative debridement, nonhealing wounds, and adverse effects were analyzed based on Wagner grades, using RevMan 5.4.1 and Microsoft Excel.
RESULTS
Hyperbaric oxygen therapy was significantly superior to other treatments for wound healing rates 8 or more weeks after the final treatment (RR = 2.39; 1.87-3.05; < 0.00001) minor/distal amputations (RR = 0.58; 0.43-0.80; < 0.007), and major/proximal amputations (RR = 0.31; 0.18-0.52; < 0.00001) for the 14 studies analyzed. In addition, this therapy increased the rate of complete wound healing for Wagner grades II (RR = 21.11; 3.05-146.03; = 0.002), III (RR = 19.58; 2.82-135.94, = 0.003), and IV (RR = 17.53; 2.45-125.44; = 0.004); decreased the minor/distal amputation rate for grade III (RR = 0.06; 0.01-0.29; = 0.0004) and the major/proximal amputation rate on for grade IV (RR = 0.08; 0.03-0.25; < 0.0001); and decreased the operative debridement rate for Wagner grade II (RR = 0.09; 0.01-0.60; = 0.01).
CONCLUSIONS
Moderate-quality evidence revealed that adjunctive hyperbaric oxygen therapy improved DFU wound healing for Wagner grades II, III, and IV; prevented minor and major amputations for grades III and IV, respectively; and prevented operative debridement in grade II wounds.

Software with artificial intelligence-derived algorithms for analysing CT brain scans in people with a suspected acute stroke: a systematic review and cost-effectiveness analysis.
BACKGROUND
Artificial intelligence-derived software technologies have been developed that are intended to facilitate the review of computed tomography brain scans in patients with suspected stroke.
OBJECTIVES
To evaluate the clinical and cost-effectiveness of using artificial intelligence-derived software to support review of computed tomography brain scans in acute stroke in the National Health Service setting.
METHODS
Twenty-five databases were searched to July 2021. The review process included measures to minimise error and bias. Results were summarised by research question, artificial intelligence-derived software technology and study type. The health economic analysis focused on the addition of artificial intelligence-derived software-assisted review of computed tomography angiography brain scans for guiding mechanical thrombectomy treatment decisions for people with an ischaemic stroke. The de novo model (developed in R Shiny, R Foundation for Statistical Computing, Vienna, Austria) consisted of a decision tree (short-term) and a state transition model (long-term) to calculate the mean expected costs and quality-adjusted life-years for people with ischaemic stroke and suspected large-vessel occlusion comparing artificial intelligence-derived software-assisted review to usual care.
RESULTS
A total of 22 studies (30 publications) were included in the review; 18/22 studies concerned artificial intelligence-derived software for the interpretation of computed tomography angiography to detect large-vessel occlusion. No study evaluated an artificial intelligence-derived software technology used as specified in the inclusion criteria for this assessment. For artificial intelligence-derived software technology alone, sensitivity and specificity estimates for proximal anterior circulation large-vessel occlusion were 95.4% (95% confidence interval 92.7% to 97.1%) and 79.4% (95% confidence interval 75.8% to 82.6%) for Rapid (iSchemaView, Menlo Park, CA, USA) computed tomography angiography, 91.2% (95% confidence interval 77.0% to 97.0%) and 85.0 (95% confidence interval 64.0% to 94.8%) for Viz LVO (Viz.ai, Inc., San Fransisco, VA, USA) large-vessel occlusion, 83.8% (95% confidence interval 77.3% to 88.7%) and 95.7% (95% confidence interval 91.0% to 98.0%) for Brainomix (Brainomix Ltd, Oxford, UK) e-computed tomography angiography and 98.1% (95% confidence interval 94.5% to 99.3%) and 98.2% (95% confidence interval 95.5% to 99.3%) for Avicenna CINA (Avicenna AI, La Ciotat, France) large-vessel occlusion, based on one study each. These studies were not considered appropriate to inform cost-effectiveness modelling but formed the basis by which the accuracy of artificial intelligence plus human reader could be elicited by expert opinion. Probabilistic analyses based on the expert elicitation to inform the sensitivity of the diagnostic pathway indicated that the addition of artificial intelligence to detect large-vessel occlusion is potentially more effective (quality-adjusted life-year gain of 0.003), more costly (increased costs of £8.61) and cost-effective for willingness-to-pay thresholds of £3380 per quality-adjusted life-year and higher.
LIMITATIONS AND CONCLUSIONS
The available evidence is not suitable to determine the clinical effectiveness of using artificial intelligence-derived software to support the review of computed tomography brain scans in acute stroke. The economic analyses did not provide evidence to prefer the artificial intelligence-derived software strategy over current clinical practice. However, results indicated that if the addition of artificial intelligence-derived software-assisted review for guiding mechanical thrombectomy treatment decisions increased the sensitivity of the diagnostic pathway (i.e. reduced the proportion of undetected large-vessel occlusions), this may be considered cost-effective.
FUTURE WORK
Large, preferably multicentre, studies are needed (for all artificial intelligence-derived software technologies) that evaluate these technologies as they would be implemented in clinical practice.

Meta-Analysis Review
Does Proximal Adductor Canal Block Provide Better Analgesic Efficacy than Distal Adductor Canal Block in Patients Undergoing Knee Arthroplasty: A Systematic Review and Meta-Analysis of Randomized Controlled Trials.
To compare the analgesic efficacy and adverse events of proximal versus distal ACB for adults undergoing knee arthroplasty, we searched PubMed, Cochrane, Web of Science, and Embase to identify all eligible randomized controlled trials (RCTs). The study quality of the RCTs was evaluated using the Cochrane risk of bias assessment tool. Heterogeneity among studies was examined by Cochrane Q test. Our primary outcomes were pain intensity at rest/during movement and morphine consumption. Statistical analyses were conducted by RevMan Software. Seven eligible studies involving 400 subjects were included in this meta-analysis with 202 participants in the proximal ACB group and 198 participants in the distal ACB group. The results demonstrated that proximal ACB provided significantly better pain relief at rest at 2 h (SMD -0.27, 95% CI -0.54 to -0.01, four trials, 222 participants, I = 0, p = 0.04) and 24 h (SMD -0.28, 95% CI -0.48 to -0.08, seven trials, 400 participants, I = 0, p = 0.006) following the surgery. We found no evidence of a difference in postoperative pain intensity at other timepoints. Furthermore, we noted no evidence of a difference in cumulative morphine consumption and occurrence of adverse events. Proximal ACB provides better pain relief and comparable adverse effects profile compared with distal ACB. The analgesic benefit offered by proximal ACB, however, did not appear to extend beyond the first 24 h. The overall evidence level was mostly low or very low, which requires more well-organized multicenter randomized trials in the future.

Review
This study aims to provide an updated review comparing the complication rates and clinical outcomes of intramedullary nails and locking plates (LPs) in displaced proximal humerus fracture (PHF) management. We performed a systematic review of the Cochrane Central Register of Controlled Trials, Clinical Trials Registry, EMBASE, and PubMed. Studies with level III evidence or higher comparing intramedullary nails and LPs used for internal fixation of displaced PHFs were included. The Methodological Index for Nonrandomized Studies (MINORS) criteria and Cochrane Handbook for Systematic Reviews of Interventions 5.2.0 were used to assess the risk of bias. Our meta-analysis included a comparison of method-related complications, pain scores, range of motion (ROM), and functional scores. A total of 13 comparative studies were included: five randomized controlled trials, three prospective cohort studies, and five retrospective cohort studies. The total number of patients included was 1,253 (677 in the LP group and 576 in the intramedullary nail group). Superior Constant-Murley scores and external rotation ROM were found in the LP group during the early postoperative period. However, long-term functional scores and complication rates were comparable between the two groups. We conclude that intramedullary nailing and LP fixation are both equally effective for the treatment of displaced PHFs. Neither treatment appears superior at this time, and more large-scale randomized controlled trials should be conducted to further evaluate the potential benefit of LPs in the early postoperative period.

Journal of the International AIDS... Mar 2024Disengagement from antiretroviral therapy (ART) care is an important reason why people living with HIV do not achieve viral load suppression become unwell.
INTRODUCTION
Disengagement from antiretroviral therapy (ART) care is an important reason why people living with HIV do not achieve viral load suppression become unwell.
METHODS
We searched two databases and conference abstracts from January 2015 to December 2022 for studies which reported reasons for disengagement from ART care. We included quantitative (mainly surveys) and qualitative (in-depth interviews or focus groups) studies conducted after "treat all" or "Option B+" policy adoption. We used an inductive approach to categorize reasons: we report how often reasons were reported in studies and developed a conceptual framework for reasons.
RESULTS
We identified 21 studies which reported reasons for disengaging from ART care in the "Treat All" era, mostly in African countries: six studies in the general population of persons living with HIV, nine in pregnant or postpartum women and six in selected populations (one each in people who use drugs, isolated indigenous communities, men, women, adolescents and men who have sex with men). Reasons reported were: side effects or other antiretroviral tablet issues (15 studies); lack of perceived benefit of ART (13 studies); psychological, mental health or drug use (13 studies); concerns about stigma or confidentiality (14 studies); lack of social or family support (12 studies); socio-economic reasons (16 studies); health facility-related reasons (11 studies); and acute proximal events such as unexpected mobility (12 studies). The most common reasons for disengagement were unexpected events, socio-economic reasons, ART side effects or lack of perceived benefit of ART. Conceptually, studies described underlying vulnerability factors (individual, interpersonal, structural and healthcare) but that often unexpected proximal events (e.g. unanticipated mobility) acted as the trigger for disengagement to occur.
DISCUSSION
People disengage from ART care for individual, interpersonal, structural and healthcare reasons, and these reasons overlap and interact with each other. While HIV programmes cannot predict and address all events that may lead to disengagement, an approach that recognizes that such shocks will happen could help.
CONCLUSIONS
Health services should focus on ways to encourage clients to engage with care by making ART services welcoming, person-centred and more flexible alongside offering adherence interventions, such as counselling and peer support.

Review
AIM
A positive resection margin (RM) is associated with poor survival after gastrectomy for gastric cancer (GC). However, the adequate RM length to avoid a positive RM remains controversial. We performed a systematic review to examine the RM length required to avoid a positive RM in gastrectomy for GC.
METHODS
This systematic review involved all relevant articles identified in PubMed, the Cochrane Library, Web of Science, and ClinicalTrials.gov until August 2023. The incidence of a positive RM related to the RM length and the possible incidence of a positive RM estimated from the discrepancy between the gross and pathological RM length were evaluated. The Newcastle-Ottawa Scale was used to quantify study quality.
RESULTS
Thirteen studies involving 8983 patients were analyzed. Investigation of the incidence of a positive RM in relation to the RM length showed that a proximal RM length of 6 cm guaranteed a negative RM in gastrectomy. Analyses of the possible incidence of a positive RM revealed that a negative RM would be guaranteed if the proximal RM length was 6 cm in distal gastrectomy, if the esophageal resection length was 2 cm in total gastrectomy for GC without esophageal invasion and 2.5 cm in total or proximal gastrectomy for GC with esophageal invasion or esophagogastric junction cancer, and if the distal RM length was 4 cm in proximal gastrectomy for early GC.
CONCLUSIONS
The adequate RM lengths to ensure a pathologically negative RM in each type of gastrectomy for GC were herein suggested.

Review
This systematic review aims to assess the management of knee osteoarthritis through proximal fibular osteotomy (PFO) in the Indian population by synthesizing data from various prospective cohort and interventional studies. We seek to provide an overview of the effectiveness and safety of PFO as a treatment modality and offer insights into its potential implications for clinical practice in India. A systematic search strategy was employed, targeting multiple medical databases to identify relevant studies published from 2018 to 2023. Inclusion criteria encompassed studies involving Indian patients with medial compartment knee osteoarthritis and varus deformity who underwent PFO. Data were extracted and evaluated according to the Newcastle-Ottawa Scale for observational studies. Eight studies were included in this review, each displaying varying designs, patient populations, and follow-up duration. The findings consistently indicated that PFO improved pain, knee function, and radiological outcomes, such as knee joint space and tibio-femoral angles. These improvements were generally sustained over several months to a year. The available evidence underscores the potential of PFO as a promising intervention for managing knee osteoarthritis in the Indian population, particularly in patients with medial compartment involvement and varus deformity. While these results are promising, the limitations inherent in the current literature, including study design variations and small sample sizes, necessitate further research with more extensive and diverse patient populations. This systematic review provides valuable insights for healthcare professionals and researchers, highlighting the need for more rigorous investigations and supporting the consideration of PFO as a viable treatment option for knee osteoarthritis in India.

Review
BACKGROUND/OBJECTIVE
The recent development of minimally invasive surgical techniques (MIS) has made possible the correction of adult spinal deformity (ASD) with less blood loss and shorter hospital stays. However, minimally invasive placement of pedicle screws at the proximal level of the construct can increase pseudarthrosis risk, leading to implant failure, kyphosis, and reoperations. We aggregate existing literature to describe pseudarthrosis rates at the proximal thoracic or thoracolumbar junction in MIS and subsequent reoperation rates.
METHODS
After a three-tied search strategy in PubMed, we identified 9 articles for study inclusion, describing outcomes from MIS correction of ASD, pseudarthrosis as complication, and surgery on 4+ levels. Baseline patient characteristics and combined rates of pseudarthrosis and reoperation were calculated.
RESULTS
A total of 482 patients were studied with an average [range] age of 65.5 [60.4,72], 6.3 [4.4,11] levels fused per patient, follow-up time of 28.3 [12,39] months, and 64.8% females. Pseudarthrosis was reported in 28 of 482 pooled patients (5.8%) of which 15 of 374 pooled patients (4.0%) ultimately underwent a reoperation for pseudarthrosis. Post-operative characteristics included an estimated blood loss (EBL) of 527.1 [241,1466] mL, operating time of 297.9 [183,475] minutes, and length of stay of 7.7 [5,10] days. Among the papers comparing MIS to open surgery, all reported a significantly lower EBL in patients treated with MIS.
CONCLUSION
This analysis demonstrate a measurable pseudarthrosis risk when using MIS to treat ASD, overwhelming requiring reoperation. The benefits of MIS must be considered against the drawbacks of pseudarthrosis when determining ASD management.

Meta-Analysis Review
BACKGROUND
Accelerated by technological advancements and the recent global pandemic, there is burgeoning interest in digital mental health literacy (DMHL) interventions that can positively affect mental health. However, existing work remains inconclusive regarding the effectiveness of DMHL interventions.
OBJECTIVE
This systematic review and meta-analysis investigated the components and modes of DMHL interventions, their moderating factors, and their long-term impacts on mental health literacy and mental health.
METHODS
We used a random-effects model to conduct meta-analyses and meta-regressions on moderating effects of DMHL interventions on mental health.
RESULTS
Using 144 interventions with 206 effect sizes, we found a moderate effect of DMHL interventions in enhancing distal mental health outcomes (standardized mean difference=0.42, 95% CI -0.10 to 0.73; P<.001) and a large effect in increasing proximal mental health literacy outcomes (standardized mean difference=0.65, 95% CI 0.59-0.74; P<.001). Uptake of DMHL interventions was comparable with that of control conditions, and uptake of DMHL interventions did not moderate the effects on both proximal mental health literacy outcomes and distal mental health outcomes. DMHL interventions were as effective as face-to-face interventions and did not differ by platform type or dosage. DMHL plus interventions (DMHL psychoeducation coupled with other active treatment) produced large effects in bolstering mental health, were more effective than DMHL only interventions (self-help DMHL psychoeducation), and were comparable with non-DMHL interventions (treatment as usual). DMHL interventions demonstrated positive effects on mental health that were sustained over follow-up assessments and were most effective in enhancing the mental health of emerging and older adults.
CONCLUSIONS
For theory building, our review and meta-analysis found that DMHL interventions are as effective as face-to-face interventions. DMHL interventions confer optimal effects on mental health when DMHL psychoeducation is combined with informal, nonprofessional active treatment components such as skills training and peer support, which demonstrate comparable effectiveness with that of treatment as usual (client-professional interactions and therapies). These effects, which did not differ by platform type or dosage, were sustained over time. Additionally, most DMHL interventions are found in Western cultural contexts, especially in high-income countries (Global North) such as Australia, the United States, and the United Kingdom, and limited research is conducted in low-income countries in Asia and in South American and African countries. Most of the DMHL studies did not report information on the racial or ethnic makeup of the samples. Future work on DMHL interventions that target racial or ethnic minority groups, particularly the design, adoption, and evaluation of the effects of culturally adaptive DMHL interventions on uptake and mental health functioning, is needed. Such evidence can drive the adoption and implementation of DMHL interventions at scale, which represents a key foundation for practice-changing impact in the provision of mental health resources for individuals and the community.

BACKGROUND
Adolescent multiple risk behaviour (MRB) is a global health issue. Most interventions have focused on the proximal causes of adolescent MRB such as peer or family influence, with systematic reviews reporting mixed evidence of effectiveness. There is increasing recognition that community mobilisation approaches could be beneficial for adolescent health. There are gaps in the current literature, theory and implementation that would benefit from a realist approach. We use a theory-driven evidence synthesis to assess how and why community mobilisation interventions work/do not work to prevent adolescent MRB and in what contexts.
METHODS
This realist review used a six-stage iterative process, guided by the RAMESES framework. We systematically searched PubMed, MEDLINE, PsycINFO, Web of Science, CINAHL and Sociological Abstracts, from their inception to 2021. Studies were screened for relevance to the programme theory, assessed for rigour and included based on a priori criteria. Two independent reviewers selected, screened and extracted data from included studies. A realist logic of analysis was used to develop context-mechanism-outcome configurations that contributed to our programme theory.
FINDINGS
We reviewed 35 documents describing 22 separate community mobilisation intervention studies. Most studies (n = 17) had a quality assessment score of three or four (out of four). We analysed the studies in relation to three middle range theories. To uphold our theory that these interventions work by creating a social environment where adolescents are less likely to engage in MRB, interventions should: (1) embed a framework of guiding principles throughout the community, (2) establish community readiness with population data and (3) ensure a diverse coalition with the support of intervention champions. Mechanisms such as empowerment through coalition ownership over the delivery of the intervention, cohesion across the community and motivation to work collaboratively to improve adolescent health are triggered to achieve social environment shifts. However, certain contexts (e.g. limited funding) restrict intervention success as these mechanisms are not fired.
CONCLUSIONS
For community mobilisation interventions to reduce adolescent MRB, the coalitions within them must seek to alter the social environment in which these behaviours occur. Mechanisms including empowerment, cohesion and motivation lead to this shift, but only under certain contexts.
