Meniscal preservation in the age of biologics: toward a quantitative decision algorithm for personalized repair.

BACKGROUND: Despite advances in arthroscopic repair and biologic augmentation, surgical indication for meniscal tears remains heterogeneous. No standardized framework currently integrates biomechanical, clinical, and biological determinants to guide repair versus resection. PURPOSE: To develop a quantitative decision model-the Meniscal Preservation Score (MPS)-that unifies biomechanical and biological evidence to stratify reparability potential and standardize treatment selection in meniscal surgery. METHODS: A systematic evidence synthesis conducted in accordance with PRISMA 2020 reporting standards of studies published from 2000 to 2025 in PubMed, Embase, and Scopus identified key determinants of meniscal healing. Five consistent predictors-patient age, vascularity, tear morphology, associated pathology, and activity profile-were weighted through a two-round modified Delphi consensus among ten experienced knee surgeons. The resulting 0-9-point MPS was incorporated into a stepwise decision tree linking lesion morphology, biological context, and surgical strategy. Conceptual validation used 50 simulated cases and a retrospective cohort of 45 patients to test agreement between algorithm recommendations and expert surgical decisions. RESULTS: The MPS achieved 86% concordance with expert judgment in simulation and 84% agreement in clinical validation. In this retrospective exploratory cohort, cases in which surgical management was concordant with MPS recommendations demonstrated higher mean IKDC scores at 24 months and lower observed reoperation rates. These findings should be interpreted as associative rather than causal, as treatment allocation was not controlled and discordant cases may have represented inherently more complex pathology. CONCLUSION: The MPS represents an evidence-informed decision-support framework designed to systematize reparability assessment. While exploratory analyses suggest structural coherence with expert reasoning, prospective implementation and external validation are required before clinical adoption as a predictive tool. LEVEL OF EVIDENCE: conceptual model with exploratory validation.

Depressive Symptoms and Smoking Cessation Among Adolescents and Young Adults Who Smoke: A Prospective Cohort Study.

PURPOSE: This study examined the bidirectional prospective associations between depressive symptoms and smoking cessation among adolescent and young adults who smoke. METHODS: Data on 1,151 participants aged ≤25 years who smoke and receive peer-led quitline counseling in Hong Kong (2016-2022) were analyzed. Exposures included baseline depressive symptoms and smoking cessation (self-reported 7-day abstinence) at 1, 3, and 6 months; Outcome measures included smoking cessation at 1, 3, and 6 months and depressive symptoms at 6 months. Depressive symptoms were assessed using the Center for Epidemiologic Studies Depression Scale, with a score ≥16 indicating at risk for depression. RESULTS: More severe baseline depressive symptoms were associated with lower odds of smoking cessation at 1, 3, and 6 months, which reversely was associated with lower depressive symptoms at 6 months (all p < .05). Similarly, being at risk for depression at baseline was associated with lower odds of smoking cessation at 1 (adjusted odds ratio [aOR] .66, 95% confidential interval [CI] .47-.93) and 3 months (aOR .71, 95% CI .52-.97). Conversely, smoking cessation at 1 (aOR .40, 95% CI .23-.69), 3 (aOR .58, 95% CI .37-.92), and 6 months (aOR .44, 95% CI .29-.69) was associated with lower odds of at risk for depression at 6 months. DISCUSSION: More severe depressive symptoms were prospectively associated with lower odds of smoking cessation, while smoking cessation was associated with lower depressive symptoms and risk for depression. Integrated interventions simultaneously addressing psychological needs and smoking are warranted, when delivered in smoking cessation programs or embedded within mental health services for youth who smoke.

Screening for neurofibromatosis type 1-related optic pathway gliomas: a systematic review.

BACKGROUND: Neurofibromatosis-type 1 (NF1) is a genetic disorder characterized by developing optic pathway gliomas (OPGs) in 15%-20% of patients with higher estimates where consanguinity is prevalent. Clinically, NF1-OPG might be unpredictable with the risk of OPG progression and visual impairment. The optimal time for screening is controversial. We aim to identify the mean/median age at diagnosis of NF1-OPG and its clinical spectrum. METHODS: A systematic review of PubMed, Web of Science, and Embase databases was conducted for English-language publications from January 1993 to October 2025, exploring the visual screening of OPGs in NF1 patients, following Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines and registered in the Prospective Register of Systematic Reviews (PROSPERO ID: CRD420251036244). Inclusion criteria focused on studies reporting the age at OPG diagnosis and visual manifestations in NF1 patients. Data were extracted on demographics, age at NF1 and OPG diagnosis, tumour location (using the Dodge classification), and presenting symptoms. Sixteen studies met the inclusion criteria. RESULTS: Among 4 739 NF1 patients, 818 had OPGs, with prevalence ranging from 4.2% to 46.7%. The age at NF1 diagnosis ranged from 0 to 132 months (mean: 18-38 months), and at OPG diagnosis from 0-240 months (median: 29-58 months). Approximately 58.4% of OPGs were asymptomatic, and 25% were above the age of 5 years. Among symptomatic patients, the most frequent presentations included decreased visual acuity (62%), abnormal optic disc (45%), proptosis (20%), strabismus (12%), and visual field defects (7%). CONCLUSIONS: NF1-related OPGs typically present early within 6 years of age. Early ophthalmologic and/or radiologic screening at the time of NF1 diagnosis enhances the detection of silent OPGs.

[Clinical efficacy and cost-effectiveness evaluation of acupoint thread-embedding for knee osteoarthritis of early to middle stage].

OBJECTIVE: To compare the clinical efficacy of acupoint thread-embedding and electroacupuncture for knee osteoarthritis (KOA) of early to middle stage, and to evaluate their economic benefits based on cost-effectiveness analysis. METHODS: A total of 66 patients with KOA of early to middle stage were randomized into an acupoint thread-embedding group (33 cases, 1 case dropped out) and an electroacupuncture group (33 cases, 2 cases dropped out). In the acupoint thread-embedding group, acupoint thread-embedding was applied at Xuehai (SP10), Liangqiu (ST34), Weizhong (BL40), etc.on the affected side, once a week. In the electroacupuncture group, electroacupuncture was applied at Xuehai (SP10),Liangqiu (ST34), Zusanli (SP36), etc. on the affected side, with disperse-dense wave, in frequency of 2 Hz/100 Hz, once every other day, 3 times a week. Both groups were treated for 4 weeks. The Western Ontario and McMaster Universities arthritis index(WOMAC) score was observed before and after treatment, as well as at the follow-up of 4 weeks after treatment completion,the visual analogue scale (VAS) score of pain and the Lysholm score were observed before and after treatment in the two groups. The clinical efficacy was evaluated between the two groups, and the cost-effectiveness analysis was conducted based on WOMAC score. RESULTS: After treatment, the WOMAC and pain VAS scores were decreased compared with those before treatment (P<0.001), and the Lysholm scores were increased compared with those before treatment (P<0.001) in both groups. At follow-up, the WOMAC score in the acupoint thread-embedding group was decreased compared with that before treatment (P<0.001), and was lower than that in the electroacupuncture group (P<0.05). The total effective rates were 93.8% (30/32) in the acupoint thread-embedding group and 87.1% (27/31) in the electroacupuncture group, with no statistically significant difference between the two groups (P>0.05). The cost-effectiveness ratio (CER) and the total cost of the acupoint thread-embedding group were lower than those in the electroacupuncture group. CONCLUSION: Both acupoint thread-embedding and electroacupuncture can improve knee joint function, pain and stability in patients with KOA of early to middle stage, with comparable efficacy, and the acupoint thread-embedding group shows better long-term efficacy, lower cost and higher economic benefit.

Retinal microstructural alterations as early phenotypes of depression in radiogenomics analysis.

BACKGROUND: With the increasing prevalence of depression, there is an urgent clinical need for early screening in depression. The retina offers a promising window for early screening in depression due to its rapid, non-invasive, objective, eye-brain correlated characteristics, but previous research has yielded conflicting alterations in retinal microstructure in depression. METHODS: We screened retinal optical coherence tomography and brain magnetic resonance imaging data in the UK Biobank to enroll 23,225 participants for retinal study of depression occurrence, and 1475 participants for the eye-brain association study. We also used genetic data (ID: ebi-a-GCST90014267 and ukb-d-20,448) from the Integrative Epidemiology Unit Open Genome-Wide Association Study for Mendelian randomization analysis. We used Cox regression to assess the association between retinal microstructure and depression risk, Mendelian randomization to infer causality, and mediation analysis to explore retina-brain pathway association. RESULTS: The Cox regression analysis showed that retinal ganglion cell-inner plexiform layer (GCIPL) thickness remained a significant predictor of depression. The Mendelian randomization analysis indicated a positive statistical association between GCIPL thickness and depression. Moreover, there was a significant positive correlation (all p < 0.001) between the volume of specific depression-related brain regions and the GCIPL thickness. Adjusting for age, sex, and head size, the mediation analysis provided preliminary evidence for a potential anatomical pathway linking retinal GCIPL thickness to depression-related brain regions through primary visual cortex and secondary visual cortex volumes. CONCLUSION: Thickened retinal GCIPL is a potential early phenotype of depression and has a potential association pathway with depression-related brain regions using a radiogenomics approach.

Age at menopause and subjective cognitive symptoms predict digital cognitive outcomes at the gynecological Well-Woman visit.

INTRODUCTION: Women are at increased risk for Alzheimer's Disease (AD). Growing evidence suggests that the menopausal transition may represent a vulnerable window for development of AD-related pathology. Yet, women are diagnosed with AD later than men. Conducting routine cognitive screenings and integrating information about both cognitive symptoms and age at menopause may help address sex-based disparities in detection and prevention. This study investigated whether subjective cognitive symptoms, in combination with age at menopause, were associated with performance on a digital cognitive task in postmenopausal women. METHODS: 183 postmenopausal women (mean age = 63.8, range = 45-85) were recruited after their Well-Woman visit. Participants completed the Screener for Cognitive Problems in Everyday Life (SCoPE) to assess subjective cognitive symptoms, followed by a sensitive measure of objective cognition: the Linus Health Digital Clock and Recall (DCR™). Information was also collected on age at menopause. We examined associations of subjective cognitive symptoms and age at menopause with digital cognitive performance, adjusting for age, education and depression. Model fit was evaluated using adjusted R2, AIC, and BIC. RESULTS: 48.1% of women reported one or more cognitive symptoms on the SCoPE. On objective testing, 73.2% scored in the normal range, 20.8% in the borderline range, and 6.0% in the impaired range. SCoPE total score was negatively associated with objective cognitive performance in adjusted models (B = -.12, p = .03). Age at menopause showed a significant quadratic association with cognitive performance (B = -0.006, p<.001). SCoPE total was not associated with DCR subtests, while age at menopause predicted both Delayed Recall and Clock Drawing. CONCLUSION: Subjective cognitive symptoms and age at menopause were associated with lower performance on a sensitive, objective cognitive test. Findings support routine cognitive screening and suggest that subjective cognitive symptoms as well as age at menopause are associated with cognitive function.

Quality assessment, prognostic factors, and biomarkers for brain tumor analysis: a comprehensive systematic review.

The brain tumors possess different causative factors and properties, making their diagnosis and treatment difficult. Growth of these cancers usually leads to compression of the adjacent nerves and obstruction of the flow of cerebrospinal fluid, thus leading to increase in intracranial pressure. This affects the working of brain in many ways; thus, the difficulty involved in its treatment. With the improvements in technology in neuroimaging, including Diffusion Tensor Imaging (DTI), Positron Emission Tomography (PET), and multiparametric Magnetic Resonance Imaging (mpMRI), the diagnosis process has become easy. The effectiveness of any form of therapy in such patients depends primarily on their prognosis. While it is a common practice that physicians determine the prognosis of the disease by considering the age of the patient, histological grade of the tumor, and resection status, now this method has become more comprehensive by adding molecular signature and genetic analyses to the list of criteria. Next-generation sequencing (NGS) allows a reliable molecular classification. It increases the level of risk stratification, facilitating the application of therapies tailored to individual patients. Thus, molecular oncology has greatly changed our views on brain tumors' pathology and prognosis while neoadjuvant treatments aim at increasing the survival rate. On the other hand, radiogenomics is a field of study that combines non-invasive imaging phenotypes and genomic information in order to find unique molecular signatures of tumors without collecting samples from tumors. Molecular biomarkers are absolutely essential in the diagnosis of cancer, treatment monitoring, and recurrence of cancer. Advances in liquid biopsy technology, particularly the methods for circulating tumor DNA (ctDNA) and Extracellular Vesicle (EV) based analysis, have enabled the possibility of non-invasive monitoring of the progression of the tumors over time. This review highlights key studies and important scientific works about imaging technologies, biomarkers, and prognostic factors of malignant brain tumors.

Patterns and implications of co-use between vaping and hallucinogens: a systematic review and meta-analysis.

BACKGROUND: The co-occurrence use of e-cigarettes and hallucinogens has become increasingly common, particularly among youth and young adults. However, evidence regarding the association between these behaviors remains limited and fragmented. This systematic review and meta-analysis aimed to synthesize current evidence, examining the correlation between hallucinogen use and the likelihood of being an e-cigarette user. METHODS: A comprehensive search was conducted in PubMed, Scopus, Web of Science, EMBASE, and Cochrane CENTRAL up to June 2025. Eligible studies measured both hallucinogen and e-cigarette use and reported quantitative associations between these behaviors. Data extraction and risk-of-bias assessments were performed independently by three reviewers using the Newcastle-Ottawa Scale. Pooled effect sizes were calculated using a random-effects model (REML). Certainty of evidence was evaluated with the GRADE approach. RESULTS: Eleven studies met the inclusion criteria (n = 247,904), and seven were included in the meta-analysis (n = 217,478). The pooled analysis demonstrated that hallucinogen users had 4.47 times higher odds of being e-cigarette users (OR: 4.47, 95% CI 2.72 to 7.34; p < 0.001; I2 = 95.7%, n = 7). The certainty of evidence was rated as low. CONCLUSIONS: Hallucinogen use is directionally and strongly associated with e-cigarette use across diverse populations. Although the direction of association was consistent across studies, the magnitude of effect was heterogeneous. These behaviors likely share psychosocial and environmental determinants, although alternative explanations, including shared genetic liability, recall bias, and residual confounding, cannot be excluded. Further longitudinal studies are needed to clarify the underlying mechanisms of this association and establish temporality. The findings also support integrating hallucinogen-use screening into e-cigarette prevention and harm-reduction programs targeting youth and young adults.

Impact on analgesia, diaphragmatic function, and recovery between erector spinae plane block versus superior trunk block in arthroscopic shoulder surgery: a randomized controlled trial.

BACKGROUND: Effective analgesia and preservation of diaphragmatic function are key considerations in analgesia for shoulder surgery. The superior trunk block provides analgesia with reduced phrenic nerve involvement, while the erector spinae plane block offers minimal impact on diaphragm motion. This randomized controlled trial compared the analgesic efficacy, impact on diaphragmatic motion, and postoperative recovery between the two blocks. METHODS: Sixty patients undergoing arthroscopic shoulder surgery were randomized to receive either erector spinae plane block or superior trunk block. Primary outcomes were postoperative VAS and changes in diaphragmatic excursion. Secondary outcomes included Quality of Recovery-15 (QoR-15) scores, morphine-equivalent consumption, and the handgrip strength motor blockade. RESULTS: The superior trunk block resulted in significantly lower dynamic VAS at 1-h postoperatively (0.1 [0.0, 0.2] vs. 5.7 [4.0, 7.6]; p < 0.001) and reduced 24-h morphine consumption (7.8 [2.5, 15.0] mg vs. 12.7 [7.5, 17.3] mg; p = 0.038) compared to the erector spinae plane block. However, diaphragmatic excursion was better preserved in the erector spinae plane block group (8.37% ± 20.7% vs. -20.09% ± 22.2%; p < 0.001), with a lower incidence of partial hemidiaphragm paresis (3.3% vs. 46.7%; p < 0.001). At 24 h postoperatively, QoR-15 scores were higher in the superior trunk block group (p = 0.047), and no patient in either group developed handgrip motor blockade. CONCLUSIONS: Superior trunk block offers superior early postoperative analgesia and better overall recovery, while erector spinae plane block minimizes diaphragmatic impairment. However, the erector spinae plane block may represent an option only in carefully selected patients at high respiratory risk, acknowledging its significantly poorer early analgesic profile.

Ameliorating Effects and Autonomic Mechanisms of Transcutaneous Auricular Vagus Nerve Stimulation on Abdominal Pain in Patients With Functional Dyspepsia and Irritable Bowel Syndrome.

BACKGROUND: Patients with functional dyspepsia (FD) and irritable bowel syndrome (IBS) often experience abdominal pain and reduced quality of life and need effective treatments. This exploratory study aimed to evaluate whether transcutaneous auricular vagus nerve stimulation (taVNS) could improve abdominal pain and quality of life in patients with FD and IBS, and whether the effects were mediated via the autonomic mechanisms. METHODS: A total of 64 patients with abdominal pain (43 FD and 21 IBS) with a pain score of 3 out of 10 or higher were randomized to receive 2 weeks of taVNS or sham-taVNS treatment. The primary outcome was numeric rating scale (NRS) for abdominal pain. The dyspeptic symptom scales (DSS), IBS symptom severity scale score (IBS-SSS), anxiety and depression scores, and the SF36 quality of life scale were assessed before and after the treatment. The electrocardiogram was also recorded for the assessment of autonomic function at baseline and after the treatment. KEY RESULTS: (1) taVNS reduced the abdominal pain score (p < 0.001 for both FD and IBS), the frequency of abdominal pain (p < 0.001 for both FD and IBS), and overall symptom scores in both FD patients and IBS patients (p < 0.001 for FD and IBS). There was no significant difference in the effect of taVNS on abdominal pain between FD and IBS patients. (2) taVNS improved quality of life compared with baseline in both FD and IBS patients. (3) taVNS decreased anxiety (p < 0.001) and depression (p < 0.001). (4) taVNS increased vagal activity. At the end of the taVNS treatment, the vagal activity was negatively correlated with the pain score (r = -0.491, p = 0.004). CONCLUSIONS: Non-invasive taVNS improves abdominal pain, quality of life, and anxiety and depression in patients with FD and patients with IBS, possibly attributed to the enhancement of vagal activity.

Perioperative safety and survival outcomes of robot-assisted partial nephrectomy in elderly patients with localized renal cell carcinoma: an overlap-weighted Asian cohort study.

The value of robot-assisted partial nephrectomy (RAPN) in elderly Asian patients with localized renal cell carcinoma (RCC) remains insufficiently defined. We retrospectively analyzed 339 patients (≥ 70 years) with localized RCC treated at a single Asian center between 2015 and 2025, including 119 undergoing partial nephrectomy (PN) and 220 undergoing radical nephrectomy (RN). Propensity score overlap weighting (OW) was applied to compare PN versus RN and, within the PN cohort, RAPN versus laparoscopic partial nephrectomy (LPN). Three open partial nephrectomy cases were summarized descriptively and retained only in exploratory sensitivity analyses. Weighted logistic regression and Cox models with robust standard errors evaluated Clavien-Dindo grade ≥ II complications and overall survival (OS). After OW, PN was associated with better early postoperative renal functional preservation than RN but a greater incidence of grade ≥ II complications (36.4% vs. 17.6%; weighted p < 0.001); OS was similar. Within the PN cohort, RAPN had longer operative time than LPN (weighted p = 0.030), whereas warm ischemia time, early postoperative eGFR, and grade ≥ II complications (31.8% vs. 40.4%; weighted p = 0.414) were not significantly different. Exploratory analyses favored RAPN, but only one death occurred in this group, and residual confounding remains possible. PN may preserve early renal function in selected older patients, while RAPN appears feasible in experienced centers; its survival association remains hypothesis-generating.

[Efficacy and safety of thoracic paravertebral block combined with thoracic nerve block for acute herpes zoster neuralgia involving upper thoracic dermatomes in middle-aged and elderly patients].

To investigate the clinical efficacy and safety of ultrasound-guided thoracic paravertebral block (TPVB) combined with pectoral nerve block (Pecs) in the treatment of acute herpetic neuralgia (AHN) involving the upper thoracic segments in middle-aged and elderly patients, a prospective study was conducted. A total of 70 middle-aged and elderly patients with upper thoracic AHN who visited the Department of Pain Medicine at Nanjing Drum Tower Hospital, Affiliated Hospital of Medical School, Nanjing University, from June to December 2023, were enrolled and randomly divided into a control group and an experimental group using a random number table, with 35 patients in each group. The control group received TPVB once weekly for a total of 3 sessions, while the experimental group received TPVB combined with Pecs block using the same regimen. Outcome measures included the Visual Analogue Scale (VAS) for pain, Pittsburgh Sleep Quality Index (PSQI), 7-item Generalized Anxiety Disorder Scale (GAD-7), 9-item Patient Health Questionnaire (PHQ-9), treatment satisfaction score, incidence of postherpetic neuralgia (PHN), rescue analgesia, and adverse events. Assessments were conducted at 1, 4, 8, and 12 weeks post-treatment, and between-group differences were compared. Ultimately, 33 patients in the experimental group and 31 in the control group completed the follow-up and were included in the final analysis. The results showed that both groups demonstrated significant improvements in VAS scores, PSQI, GAD-7, PHQ-9, and satisfaction scores compared with baseline (all P<0.05). Compared with the control group, the experimental group exhibited significantly lower VAS scores and higher satisfaction scores at 1, 4, and 8 weeks post-treatment (P<0.05), as well as significantly lower PSQI, GAD-7, and PHQ-9 scores at 4 and 8 weeks (P<0.05). There were no statistically significant differences between the two groups in the incidence of PHN, rescue analgesia, or adverse events (all P>0.05). This study demonstrates that compared with TPVB alone, the combination of TPVB and Pecs block provides better pain relief, improves sleep quality, and alleviates anxiety and depression in middle-aged and elderly patients with upper thoracic AHN, with a favorable safety profile.

Insights from changes in NDEV biomarkers of metabolism: effects of PPARγ and GLP1 receptor agonists on brain metabolism.

BACKGROUND: Insulin resistance (IR) is implicated in central nervous system disorders, including depression and Alzheimer's disease (AD). METHODS: We analyzed biological samples from two cohorts of clinical trial participants: (1) participants with unremitted depression after six months of treatment as usual who received pioglitazone (PPARγ agonist, N = 12) or placebo and (2) middle-aged participants at genetic risk for AD who received liraglutide (glucagon-like peptide 1 [GLP1] receptor agonist, N = 15) or placebo. These cohorts, which previously showed treatment-related improvements in peripheral IR, were used to assess the effects of pioglitazone and liraglutide on CNS insulin signaling using neuron-derived extracellular vesicles (NDEVs) as biomarkers. We utilized biological samples to measure biomarkers of IR in NDEVs. Eleven Akt-mTOR pathway proteins were measured before and after 12 weeks of treatment in both groups. RESULTS: Participants who received pioglitazone experienced broader changes, with significant increases in GSK3β (Ser9), mTOR (Ser2448), and RPS6 (Ser235/Ser236; all P ≤ .02) compared with placebo, and 77% of participants showed mTOR (Ser2448) response. Participants who received liraglutide demonstrated significantly increased NDEV-associated phosphorylated Akt (Ser473) and mTOR (Ser2448; P = .04 and P = .025, respectively) compared with placebo, with 40% and 30% of participants in the liraglutide group showing biomarker response in both Akt (Ser473) and mTOR (Ser2448), respectively. These effects appeared relatively independent from changes in fasting plasma insulin and glucose concentration at 120-minutes during the oral glucose tolerance test. DISCUSSION: Our findings demonstrate CNS-specific biomarker responses to both PPARγ agonists and GLP1 receptor agonists.

Smartphone Apps for Preventing Adolescent Health Problems Among Health Care Professionals: Systematic Search and Quality Assessment.

BACKGROUND: Health care professionals must consider multiple dimensions of prevention when consulting with adolescents. Identifying risky behaviors early in adolescence is crucial for reducing both morbidity and mortality. General practitioners are increasingly eager to incorporate digital tools for prevention into their consultations with adolescents; however, the relevance and clinical validity of these digital tools are not always established or well-known. Consequently, primary care professionals require guidance and support in selecting relevant mobile health (mHealth) tools. OBJECTIVE: The aim of this study is to identify relevant and useful digital apps to help primary care professionals detect at-risk adolescents across all recommended areas of prevention: orthopedics, mental health, substance abuse, risk behaviors, sexual health, vaccinations, social relationships, and nutrition. METHODS: A systematic review of smartphone apps, with an analysis of content quality, was carried out by 4 researchers using the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) checklist. The App Store and Google Play Store platforms were surveyed. The inclusion criteria were as follows: free of charge, date of last update, availability in French or English, relevance of the preventive approach to adolescents, and scientific validation. Four health care professionals assessed the apps: 2 selected the apps relevant to health care professionals, then 3 analyzed these apps using the French version of the Mobile App Rating Scale (MARS-F). Intraclass correlation coefficient, model (2,1) (2-way random effects, absolute agreement, single measures); standard error of measurement; and mean absolute error were also calculated. RESULTS: A total of 976 apps were identified, 49 of which had disappeared from the platforms prior to analysis. Nine apps were retained. Seven (0.72%) were included after evaluation using the MARS-F: 2 on mental health and 5 on sexual health (including 3 on contraception only). The mean MARS-F interrater score ranged from 2.5/5 to 3.8/5. The global MARS-F score demonstrated a pooled SD of 0.60 and an intraclass correlation coefficient (2,1) of 0.0003, resulting in a calculated standard error of measurement of 0.60. The average discrepancy between raters was a mean absolute error of 0.53. CONCLUSIONS: No similar studies have been identified in the literature that specifically focus on mobile apps designed to support health care professionals in delivering preventive care to adolescents. Of the 8 areas of prevention identified as relevant for adolescents, only 3 are addressed by the apps validated through our methodology (5 focus on sexual health). Consequently, current apps are insufficient to support health care professionals in their overall preventive work with adolescents. Such a review should be conducted systematically prior to the development of any new tool to prevent duplication and channel creative efforts toward truly innovative digital solutions. Furthermore, a thorough analysis of relevant, recommended websites is essential, as these resources complement the use of mobile apps designed for health care professionals.

MET expression by immunohistochemistry as a biomarker in pancreatic neuroendocrine tumours.

INTRODUCTION: MET (c-MET) is a receptor tyrosine kinase implicated in numerous cancers, including pancreatic neuroendocrine tumours (pNETs), by promoting cell proliferation, survival, invasion and angiogenesis. Recognizing its oncogenic potential, there is significant interest in MET-targeted therapies for malignancies like pNETs, which often develop treatment resistance. Immunohistochemistry (IHC) has become a practical method for detecting MET overexpression in cancers. This study evaluates MET expression in pNETs by IHC and assesses its correlation with prognostic variables and survival outcomes. METHODS AND RESULTS: Tissue microarrays containing well-differentiated neuroendocrine tumours from the gastrointestinal tract were analysed. The study included 125 pNET cores from 112 patients after application of inclusion criteria. MET expression was determined using the H-score system. Different variables were assessed for H-score distribution and cross-tables. Survival analyses were conducted based on progression-free survival and overall survival. Positive MET expression was found in 83.5% of cases. Higher MET H-scores were seen in patients with lymphovascular invasion (LVI), distant metastases and higher tumour grade (P < 0.05). When assessing different variables for higher MET H-scores, a significant association emerged at the 150-cut-off-point for LVI, perineural invasion, radiological evidence of progression and overall survival. For survival analysis, at a MET H-score threshold of 200, high MET expression was significantly associated with shorter progression-free survival (mean 8.7 versus 13.4 years, P < 0.05) and overall survival (mean 3.6 versus 7.7 years, P < 0.05). CONCLUSION: Elevated MET expression is linked to adverse histopathological features and worse clinical outcomes in pNET. Standardizing MET IHC evaluation is critical as anti-MET therapies develop, and identifying patients likely to benefit from these treatments remains essential.

Integrated genomic and biochemical diagnosis of a novel homozygous start-loss variant in AKR1D1 associated with neonatal cholestasis.

INTRODUCTION: Congenital bile acid synthesis defects are rare autosomal recessive disorders that typically present in early infancy with cholestasis, progressive liver dysfunction, and, in severe cases, acute liver failure. These conditions may mimic other metabolic diseases detected in newborn screening, complicating early diagnosis. The AKR1D1 gene encodes Δ4-3-oxosteroid 5β-reductase, a key enzyme in primary bile acid synthesis, and pathogenic variants cause bile acid synthesis defect type 2 (OMIM #235555). CASE DESCRIPTION: We report a 3-month-old male infant with severe neonatal cholestasis and a history of elevated tyrosine levels in newborn screening. Pregnancy was high risk and unmonitored, with birth outside a hospital. Parental consanguinity was first-degree. Early metabolic evaluation showed transient normalization of tyrosine levels, but subsequent analyses revealed recurrent hyper-tyrosinemia. Urinary organic acids showed increased 4-hydroxyphenyl metabolites, with absent succinylacetone, excluding tyrosinemia type I. Progressive cholestasis developed, accompanied by coagulopathy, hyperbilirubinemia, hyperammonemia, and markedly elevated alpha-fetoprotein. Imaging revealed no structural liver abnormalities. Clinical exome sequencing identified a novel homozygous start-loss variant in AKR1D1, likely abolishing functional enzyme production. Metabolic studies confirmed increased urinary excretion of 3-oxocholenoic acids consistent with abnormal bile acid synthesis and supporting a diagnosis of bile acid synthesis defect type 2. Oral cholic acid therapy led to stabilization and improvement in clinical and biochemical parameters. DISCUSSION/CONCLUSION: This case illustrates the diagnostic complexity of neonatal cholestasis, particularly when initial metabolic findings suggest alternative etiologies. It highlights the importance of newborn screening as a tool for broader diagnostic suspicion and the critical role of early molecular diagnosis and multidisciplinary care. Timely recognition and targeted therapy can improve outcomes, prevent liver transplantation, and enable accurate genetic counseling, especially in consanguineous families.

The Effect of Pulsed Electromagnetic Field on Pain and Foot Function Index in Patients With Plantar Fasciitis.

The plantar fascia is a thick band of connective tissue that originates from the heel, and its inflammation is the most common cause of heel pain in adults. The Pulsed Electromagnetic Field (PEMF) is a non-invasive modality in the field of physiotherapy. This study aimed to determine the effects of PEMF on pain scores and the Foot Function Index (FFI) in patients with plantar fasciitis (PF). In this clinical trial study, 40 patients with PF, aged between 20 and 68 years, were randomly assigned in a block design into two groups: the Conventional Physiotherapy (CP) group and the CP plus PEMF (CPP) group. The Numerical Pain Rating Scale (NPRS) and the FFI questionnaire were used to assess the pain score (morning and evening pain) and foot function, respectively. Assessments were conducted before the study, at the tenth session of the CP and CPP groups, and 4 weeks later. The study variables in both the CP and CPP groups changed significantly (p < 0.05). In comparing the results between the two groups, the reduction in evening pain scores in the CPP group was significant compared to the CP group (p < 0.05). In comparison, there was no significant difference in morning pain scores between the two groups. The FFI score in the CPP group significantly decreased compared to the CP group. Both CP and CPP are effective in reducing pain and the FFI in patients with PF. The addition of PEMF to CP demonstrates a more significant effect on reducing evening pain and somewhat on reducing the FFI in patients compared to CP alone. However, it did not have an additional effect on reducing morning pain. Bioelectromagnetics. 00:00-00, 2026. © 2026 Bioelectromagnetics Society.

Healthcare transition readiness in an adolescent and young adult urologic population: The ADHERENT study.

INTRODUCTION: There is a paucity of research regarding transition to adult services within pediatric and adolescent urology. Several recent articles have discussed the barriers in transitioning urologic patients from pediatric to adult health care, but empiric data that may drive intervention are lacking. This study proposes to begin to address this gap in literature and to provide information that may lead to improved understanding of how best to support transition in urologic care. OBJECTIVES: 1) to identify modifiable and non-modifiable factors related to transition readiness as measured by Transition Readiness Assessment Questionnaire (TRAQ) scores in a congenital urologic population and 2) to evaluate the relationships between TRAQ scores (a validated questionnaire measuring transition readiness) and scores measuring anxiety levels related to transition (using an adapted, non-validated questionnaire). STUDY DESIGN: This is a cross-sectional study of adolescent and young adult patients with complex congenital urologic diagnoses. Subjects were electronically administered the validated TRAQ and a study-developed ADHERENT survey, which assesses anxiety and worry surrounding transition. Regression models for the outcomes of the TRAQ and ADHERENT scales were developed to assess multivariable associations with variables of clinical importance. RESULTS: The youngest subgroup (14-17 years of age) compared to the oldest subgroup (21-25 years of age) had significantly lower TRAQ scores [regression estimate = 12.3 (95 % CI: 2.9, 21.7), p = 0.010]. Additionally, single participants versus those in a stable relationship had significantly lower TRAQ scores [estimate = 8.7 (95 % CI: 1.9, 15.4), p = 0.012]. The Spearman correlation coefficient between TRAQ and ADHERENT scores was 0.52 (p = <0.001), indicating a positive, moderate relationship between the two measures, suggesting more readiness correlated with less anxiety. DISCUSSION: This study found that age, higher education, and stable relationship status were associated with higher measures of transition readiness. There was a correlation found between more transition readiness and less anxiety surrounding transition. This finding can be used to inform future research and emphasizes the need for multidisciplinary support throughout the transition process. CONCLUSION: Early discussion of transition of care and education around transition readiness are not the only solution to improving transition success. The second phase of ADHERENT seeks to understand the patient experience and to include adolescents and young adults in shaping effective healthcare transition strategies.
