BACKGROUND
Modified ride-on cars (MROC) are a low-cost option to provide self-directed mobility to children with mobility limitations, in lieu of or as a precursor to other powered mobility devices.
OBJECTIVES
We appraised evidence to (1) describe and categorize MROC study characteristics, (2) synthesize existing knowledge of children's use of MROCs and (3) frame outcomes within the International Classification of Functioning, Disability and Health (ICF) framework.
METHODS
Articles were identified through four electronic databases: Medline, CINAHL, PsycNET, and Web of Science. We included all published, peer-reviewed studies involving MROC use. Relevant data were extracted, and articles were appraised using the American Academy of Cerebral Palsy and Developmental Medicine criteria for group and single-subject designs.
RESULTS
23 studies met inclusion criteria of 204 titles identified from 1980 to 2021. Study designs included case studies, case series, group designs, and qualitative research, but only three studies were rated evidence level III or higher. Children with a range of disabilities used MROCs across multiple settings, including the home, hospital, and community, though use and adherence varied widely. Positive impacts were reported on a range of outcomes related to the ICF framework, with an emphasis on activity and participation.
CONCLUSIONS
MROC studies have primarily addressed activity and participation, with most studies suggesting increased functional mobility and social interactions due to MROC use. More robust research designs with larger samples are needed in order to develop evidence-based strategies for MROC use.IMPLICATIONS FOR REHABILITATIONPhysical and occupational therapists may consider using MROCs as a therapeutic tool or accessible play opportunity as part of a multi-modal approach to increase children's mobility, family engagement, and participation in community life.Personal (e.g., child's enjoyment) and environmental factors (e.g., caregiver attitudes and stress) must be considered when developing plans of MROC use.

Review
BACKGROUND
The faecal immunochemical test (FIT) is an inexpensive and convenient modality to screen for colorectal cancer. However, its one-time sensitivity for detecting colorectal cancer and cancer precursors is limited. There is growing interest in using the non-haemoglobin contents of FIT residual buffer to enhance colonic neoplasia detection.
AIM
To establish from the literature a framework to catalogue candidate biomarkers within FIT residual buffer for non-invasive colorectal cancer screening.
METHODS
The search strategy evaluated PubMed, Scopus, Web of Science, Embase, and Google Scholar for publications through 25 October 2023, with search terms including FIT, buffer, OC-sensor, biomarkers, microbiome, microRNA (miR), colon, rectum, screening, neoplasm, and early detection. Studies employing home-based collection samples using quantitative FIT first processed for haemoglobin were included. One author reviewed all articles; a second author completed a 20% full-text audit to ensure adherence to eligibility criteria.
RESULTS
A broad search yielded 1669 studies and application of eligibility criteria identified 18 relevant studies. Multiple protein, DNA/RNA, and microbiome biomarkers (notably haptoglobin, miR-16, miR-27a-3p, miR-92a, miR-148a-3p, miR-223, miR-421, let-7b-5p, and Tyzzerella 4) were associated with colorectal neoplasia. Furthermore, studies highlighted the short-term stability of biomarkers for clinical use and long-term stability for research purposes.
CONCLUSIONS
This scoping review summarises the framework and progress of research on stability of biomarkers in FIT residual buffer and their associations with colorectal neoplasia to guide opportunities for further confirmatory studies to enhance colorectal cancer screening.

Review
Endometriosis is a benign condition affecting women of reproductive age. A potential association with ovarian cancer has been documented. Atypical endometriosis (AE) is characterized by deviations from the typical microscopic appearance of endometriosis, including cytologic and architectural atypia. AE has been recognized as a potential precursor to endometriosis-associated ovarian cancers (EAOC), particularly endometrioid and clear cell subtypes. AE presents challenges in diagnosis due to its diverse clinical and pathological features, often requiring careful histological evaluation for accurate identification. Architectural AE, defined by localized proliferation of crowded glands with atypical epithelium resembling endometrial neoplasia, and cytologic AE, characterized by nuclear atypia within the epithelial lining of endometriotic cysts, are key subtypes. Immunohistochemical and molecular studies have revealed aberrant expression of markers such as Ki67, COX-2, BAF250a, p53, estrogen receptor, progesterone receptor, and IMP-3. Long-term follow-up studies suggest relatively low recurrence and malignant transformation rates among patients with AE, but uncertainties persist regarding its exact malignancy potential and optimal management strategies. Integration of artificial intelligence and shared molecular aberrations between AE and EAOC may enhance diagnostic accuracy. Continuous interdisciplinary collaboration and ongoing research efforts are crucial for a deeper understanding of the relationship between endometriosis and carcinogenesis, ultimately improving patient care and surveillance.

Review
Obesity is a leading risk factor for endometrial cancer and its precursor, endometrial hyperplasia (EH). Currently, weight loss is recommended for people with EH and obesity, but evidence to guide weight management as primary or adjunctive therapy is limited. This systematic review aims to assess the role of weight loss in inducing histopathological regression of EH in women with obesity. A systematic search of Medline, PubMed, Embase and The Cochrane Library databases was conducted in January 2022. Studies reporting on participants with EH who underwent weight loss interventions, incorporating comparisons of pre- and post-intervention histology, were included. Studies were limited to those published in English with full text available. Six studies met the inclusion criteria, all of which reported outcomes after bariatric surgery. Three studies reported outcomes for the same group of participants, therefore only one outcome set was included. Pre-operative endometrial biopsy results were available for 167 women, and 81 had post-operative biopsies reported. Nineteen women (11.4% of those biopsied) had EH pre-operatively; 17 underwent repeat sampling post-operatively. Twelve (71%) had complete histological resolution, 1 (6%) had partial regression from complex hyperplasia to simple hyperplasia, 1 (6%) had persistent atypical hyperplasia, and 3 (18%) had persistent simple hyperplasia. One patient with a normal pre-intervention biopsy had simple hyperplasia post-operatively. Due to poor quality and overall scarcity of data, the role of weight loss in the primary or adjunctive treatment of EH is unknown. Future studies should prospectively assess weight loss modalities and targets, as well as use of concurrent therapies.

Review
BACKGROUND
Blastic plasmacytoid dendritic cell neoplasm (BPDCN) is a rare and aggressive hematological cancer. Due to its low incidence, researchers struggle to gather sufficient prospective data to inform clinical treatment.
OBJECTIVES
We sought to summarize the clinical characteristics and current treatment methods of BPDCN and provide more specific guidance on treatment options.
DESIGN
A systematic literature review using data from 74 Chinese BPDCN patients.
DATE RESOURCES AND METHODS
We retrospectively analyzed the clinical manifestations, treatment response, survival outcomes, and prognostic factors of six BPDCN patients treated at the First Affiliated Hospital of Zhengzhou University and 68 patients described in 28 articles published in the China Knowledge Network database since 2019.
RESULTS
In Chinese patients, the disease occurred with a male-to-female ratio of 2.52 and a median age of onset of 50 years in adults and 10 years in pediatric patients. Immunohistochemical analysis revealed distinctive immune phenotypes of BPDCN cells, characterized by high expression levels of CD4, CD56, CD123, and HLA-DR, while showing minimal to no expression of myeloperoxidase (MPO), CD20, and CD79a. There was no significant difference in the initial complete remission (CR) rate, relapse rate, and the overall survival (OS) time of patients receiving acute myeloid leukemia-like, acute lymphocytic leukemia-like, or non-Hodgkin's lymphoma-like chemotherapy regimens. Univariate analysis identified CD3 expression, male gender, and central nervous system infiltration as hazardous factors. In multivariate analysis, age proved to be an independent prognostic indicator, indicating better prognosis and longer OS time in younger patients. Notably, hematopoietic stem cell transplantation (HSCT) emerged as a significant factor in improving the survival outcomes for individuals diagnosed with BPDCN. However, further investigation is needed to explore the role of HSCT and the best timing for its implementation in pediatric BPDCN patients.
CONCLUSION
Administering HSCT during the initial CR state following inductive chemotherapy might extend the OS and improve the prognosis of patients with BPDCN.

Review
The etiology of post-arthroscopic osteonecrosis of the knee (PAONK) is still unknown. The aims of this systematic review were to analyze the main characteristics of patients who developed osteonecrosis after arthroscopy. We considered for inclusion in the review case reports, case series, retrospective and prospective clinical trial, that involved patients who developed osteonecrosis of the knee within 1 year of arthroscopy for meniscal lesion or anterior cruciate ligament rupture with or without chondropathy. In all cases, there was a pre-operative magnetic resonance imaging that excluded the presence of osteonecrosis. We used the MINORS criteria to estimate the risk of bias. A total of 13 studies that involved 125 patients were included in the review. Only 14 out of 55 patients performed the pre-operative MRI after the "window period", which we considered 6 weeks between the onset of symptoms and positive MRI findings. A diagnosis of PAONK was made for 55 patients within 1 year of surgery. Of these, 29% was treated conservatively, while 71% repeated surgery. Osteonecrosis after knee arthroscopy is a reality and surgeon shouldn't underestimate the persistence or re-emergence of symptoms after arthroscopy. It may be due to subchondral insufficiency fractures in osteopenic bone, without evidence of necrosis. However, there are not elements enough to differentiate clinical and radiological characteristics of PAONK from SPONK. Terminology should be simplified, distinguishing subchondral insufficiency fractures of the knee as a precursor of primary osteonecrosis of the knee.

In the absence of randomized controlled trials comparing tisagenlecleucel vs. standard of care (SOC) in pediatric and young adult patients with relapsed or refractory acute lymphoblastic leukemia (r/r ALL), the objective was to compare the efficacy of tisagenlecleucel with historical controls from multiple disease registries using patient-level adjustment of the historical controls. The analysis is based on patient-level data of three tisagenlecleucel studies (ELIANA, ENSIGN and CCTL019B2001X) vs. three registries in Germany/Austria. Statistical analyses were fully pre-specified and propensity score weighting of the historical controls by fine stratification weights was used to adjust for relevant confounders identified by systematic literature review. Results showed high comparability of cohorts after adjustment with absolute SMD ≤ 0.1 for all pre-specified confounders and favorable outcomes for tisagenlecleucel compared to SOC for all examined endpoints. Hazard ratios for OS, EFS and RFS were 0.54 (95% CI: 0.41-0.71, p < 0.001), 0.67 (0.52-0.86, p = 0.001) and 0.77 (0.51-1.18, p = 0.233). The OS, EFS and RFS survival probability at 2 years was 59.49% for tisagenlecleucel vs. 36.16% for SOC population, 42.31% vs. 30.23% and 59.60% vs. 54.57%, respectively. Odds ratio for ORR was 1.99 (1.33-2.97, p < 0.001). Results for OS and ORR were statistically significant after adjustment for confounders and provide evidence supporting a superiority of tisagenlecleucel in r/r ALL given the good comparability of cohorts after adjustment for confounders.

Changes in glucose metabolism, C-reactive protein, and liver enzymes following intake of NAD + precursor supplementation: a systematic review and meta-regression analysis.
BACKGROUND
There are contradictory effects regarding the effect of NAD + precursor on glucose metabolism and liver enzymes. In order to obtain a better viewpoint from them, this study aimed to comprehensively investigate the effects of NAD + precursor supplementation on glucose metabolism, C-reactive protein (CRP), and liver enzymes.
METHODS
PubMed/MEDLINE, Web of Science, SCOPUS, and Embase databases were searched using standard keywords to identify all controlled trials investigating the glucose metabolism, CRP, and liver enzymes effects of NAD + precursor. Pooled weighted mean difference (WMD) and 95% confidence intervals (95% CI) were achieved by random-effects model analysis for the best estimation of outcomes.
RESULTS
Forty-five articles with 9256 participants' were included in this article. The pooled findings showed that NAD + precursor supplementation had a significant increase in glucose (WMD: 2.17 mg/dL, 95% CI: 0.68, 3.66, P = 0.004) and HbA1c (WMD: 0.11, 95% CI: 0.06, 0.16, P < 0.001) as well as a significant decrease in CRP (WMD: -0.93 mg/l, 95% CI -1.47 to -0.40, P < 0.001) compared with control group, and was not statistically significant with respect to insulin and homeostasis model assessment of insulin resistance (HOMA-IR). However, we found no systemic changes in aspartate transaminase (AST), alanine transaminase (ALT), or alkaline phosphatase (ALP) levels after NAD + precursor supplementation. The results of the subgroup analysis showed that the intake of NAD + precursor during the intervention of more than 12 weeks caused a greater increase in the glucose level. Furthermore, Nicotinic acid supplementation (NA) causes a greater increase in glucose and HbA1c levels than nicotinamide (NE) supplementation.
CONCLUSIONS
Overall, these findings suggest that NAD + precursor supplementation might have an increase effect on glucose metabolism as well as a decrease in CRP.

Review
Muscular dystrophy is a heterogenous group of hereditary muscle disorders caused by mutations in the genes responsible for muscle development, and is generally defined by a disastrous progression of muscle wasting and massive loss in muscle regeneration. is closely associated with myogenesis, which is governed by various signaling pathways throughout a lifetime and is frequently used as an indicator in muscle research. In this review, an extensive literature search adhering to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines was performed to identify research that examined signaling pathways in living models, while quantifying expression in myogenesis. A total of 247 articles were retrieved from the Web of Science (WoS), PubMed and Scopus databases and were thoroughly examined and evaluated, resulting in 19 articles which met the inclusion criteria. Admittedly, we were only able to discuss the quantification of carried out in research affecting various type of genes and signaling pathways, rather than the expression of itself, due to the massive differences in approach, factor molecules and signaling pathways analyzed across the research. However, we highlighted the thorough evidence for the alteration of the muscle stem cell precursor in multiple signaling pathways described in different living models, with an emphasis on the novel approach that could be taken in manipulating expression itself in dystrophic muscle, towards the discovery of an effective treatment for muscular dystrophy. Therefore, we believe that this could be applied to the potential gap in muscle research that could be filled by tuning the well-established marker expression to improve dystrophic muscle.

Review
BACKGROUND
Nephrogenic rests (NR) may represent precursor lesions for Wilms tumor (WT), but their clinical course is not fully understood and no guidelines for treatment exist. This study sought to evaluate the outcomes of pediatric patients with NRs related to traditional chemotherapy and surgery.
METHODS
A PRISMA-P-compliant literature search was conducted in MEDLINE, Embase, CINAHL, Web of Science, COCHRANE, and SCOPUS from inception to June 2021. Clinical questions regarding the treatment of NRs, including chemotherapy and surgery, were developed in the population, intervention, comparison, and outcome format.
RESULTS
Twenty-five studies including 1445 patients met inclusion criteria for evaluating chemotherapy compared to observation for NRs. Eighteen studies including 1392 patients met inclusion criteria for evaluating the role of surgery for NRs. Patients with isolated NRs who underwent observation progressed to WT 33% of the time; chemotherapy reduced the rate of WT to 3.9%. Observation of multiple NRs and diffuse hyperplastic perilobar nephroblastomatosis (DHPLN) led to progression to WT 50% and 100% of the time, respectively. Chemotherapy reduced the rate of WT to 34% for multiple NRs and 46% for DHPLN. Surgery for isolated NRs reduced the risk of WT development from 23.7% in patients with incomplete excision to 3.3% with complete excision; however, 96% of patients with incompletely excised NRs had bilateral disease.
CONCLUSIONS
Observation with close surveillance for isolated NRs is safe. Treatment with chemotherapy is recommended for patients with multiple NRs and DHPLN. Surgical management of NRs should focus on renal function preservation.
LEVEL OF EVIDENCE
