Background Migraine is a highly prevalent neurological disorder with many treatment options, both pharmacological and non-pharmacological. Artificial intelligence (AI) has great potential to optimize treatment selection strategies for individual patients. This review provides an overview of AI models and the techniques used to predict migraine treatment outcomes. Methods We conducted a literature search in PubMed and examined studies that reported employing AI models to predict migraine preventive and acute treatment outcomes. We also explored incorporating AI/machine learning to enhance personalized migraine treatment strategies, including forecasting migraine attacks. Additionally, we summarized future research directions, including incorporating multimodality data, using AI frameworks for the discovery of novel treatment targets, and advancing the field with innovative AI techniques such as digital twins, conversational AI and virtual AI agents. Results Studies have employed ML and deep learning on a combination of clinical features and imaging data to predict acute or preventive migraine treatment outcomes with reported success. Continued model optimization, validation, and prospective assessment of the clinical utility of deploying ML models in real-world settings are crucial. Conclusions While AI has demonstrated success in predicting migraine treatment responses, future research incorporating novel AI techniques and diverse data sources could pave the way to advance personalized migraine treatment.

Abstract Despite concerns about the toxicity of allogeneic hematopoietic cell transplantation (alloHCT) in older patients, prospective data characterizing prevalence or risk stratification for geriatric morbidity such as disability or frailty are limited. We prospectively assessed the prognostic impact of the novel composite health assessment risk model (CHARM), a score established to predict 1-year nonrelapse mortality (NRM), among 1105 patients aged ≥60 years enrolled on the Bone Marrow Transplant Clinical Trials Network Study 1704. Secondary end points were assessed post-alloHCT at day 100 (D100), D180, and D365 in multivariable models adjusted with predetermined clinical variables. Among alloHCT survivors, the prevalence of disability by instrumental activities of daily living (IADL), frailty by the Physical Frailty Phenotype, and physical function impairment by Patient Reported Measurement Information System (PROMIS) was highest at D100 and lower on D180 and D365. Higher CHARM scores were independently associated with greater disability (coefficient, −0.64; 95% confidence interval [CI], −0.85 to −0.43; P< .001), increased frailty (coefficient, 0.19; CI, 0.081-0.31; P< .001), worse PROMIS physical function, greater PROMIS depression, increased serious organ toxicity by D100, more cognitive decline at D100, and higher mortality after acute graft-versus-host disease (GVHD) but not significantly associated with PROMIS anxiety or acute GVHD. Higher CHARM scores predicted worse disability-free survival (odds ratio [OR], 2.03; CI, 1.66-2.48; P< .001) and lower frailty-free survival (OR, 2.00; CI, 1.61-2.49). In summary, CHARM is an independent prognostic scoring system not only for NRM but also for geriatric morbidity and functional limitation–free survival through 1 year after alloHCT. Pre-alloHCT CHARM is a novel tool to aid shared decision-making for older patients. This trial was registered at www.clinicaltrials.gov as #NCT03992352.

Abstract This real-world retrospective cohort study evaluated utilization and comparative effectiveness of covalent Bruton tyrosine kinase inhibitor (cBTKi) monotherapies in relapsed/refractory mantle cell lymphoma (R/R MCL) from electronic health records in the United States. Adults with R/R MCL who received second- or third-line (2L/3L) zanubrutinib, acalabrutinib, or ibrutinib monotherapy, on or after 1 January 2018, were included. Inverse probability of treatment weighting was used in adjusted Cox models to compare real-world time-to-next treatment (rwTTNT) and overall survival (rwOS). Among 698 patients who received 2L/3L cBTKi monotherapy, 49%, 32%, and 19% received acalabrutinib, ibrutinib, and zanubrutinib, respectively. Unadjusted analyses showed median rwTTNT for 2L zanubrutinib, acalabrutinib, and ibrutinib was 14.5 (95% confidence interval [CI], 11.0-23.2), 12.8 (95% CI, 10.5-15.6), and 10.3 (95% CI, 7.6-13.7) months, and median rwOS was 26.4 (95% CI, 23.2 to not reached [NR]), 29.2 (95% CI, 22.9-38.1), and 29.3 (95% CI, 21.8-41.6) months, respectively. Median rwTTNT for 3L zanubrutinib, acalabrutinib, and ibrutinib was 21.1 (95% CI, 3.9 to NR), 9.2 (95% CI, 6.8-14.7), and 9.6 (95% CI, 4.8-18.0) months, and median rwOS was NR (95% CI, 27.3 to NR), 27.4 (95% CI, 15.1-42.2), and 27.0 (95% CI, 15.6 to NR) months, respectively. Adjusted models in the 2L/3L cohorts combined showed numerically longer rwTTNT and statistically significantly longer rwOS for zanubrutinib vs ibrutinib (hazard ratio, 0.63; 95% CI, 0.42-0.96), and trends for improved rwTTNT and rwOS for zanubrutinib over acalabrutinib. Toxicity was a frequent reason for changing to another cBTKi. These findings suggest potential improvements in rwTTNT and rwOS with the use of second- and next-generation cBTKis for R/R MCL from 2018 and beyond.

Objective We examined the weight management practices of successful high school wrestlers to contribute meaningful data to the conversations that weight-certifying clinicians and athletic trainers have with athletes at the start of the wrestling season. Understanding how elite athletes navigate weight management can inform safer and more individualized guidance during preseason assessments. Specifically, we sought to determine the proportion of state-qualifying wrestlers who competed at or above their certified minimum weight class. We also quantified the magnitude of weight change from certification to state competition and analyzed seasonal trends in both body weight and body fat percentage over a 20-year period. Design Longitudinal retrospective review. Setting Four Minnesota high schools. Patients or Other Participants State-qualifying wrestlers from 2003 to 2023. Independent Variable State-qualifying weight class. Main Outcome Measure(s) Dependent variables are certification weight, measured body fat percent, and calculated minimum weight class. Results Only 48 wrestlers (52.7%; CI = 42.5%, 63.0%) competed at state in their minimum weight class, while the other 43 competed 1 to 2 weight classes above. Thirty-six wrestlers (39.6%) gained weight over the season. Conclusions Nearly half the successful wrestlers competed in weight classes above their minimum weight, while 5% lost 9% to 18% of their body mass over the wrestling season. This suggests factors other than maximizing individual athletic potential, such as team needs to fill a weight class, influence weight management decisions. Over the 20-year span of the study, trends toward lower measured body fat percentage and lower weight fluctuations suggest influences from sports specialization and year-round training and less emphasis on extreme leanness for competitive advantage. Athletes, in consultation with their coaches and clinicians, should select a competition weight class where they can adequately fuel, train, and recover. This may not be their minimum certified weight class.

Additive manufacturing (AM) of polyetheretherketone (PEEK) offers a promising route for producing lightweight, biocompatible, and patient-specific medical implants with complex geometries. This study investigates and optimizes fused deposition modeling (FDM) parameters for fabricating small-scale PEEK medical components with improved dimensional accuracy and surface quality. PEEK’s high processing temperature and thermal contraction make precision printing of fine features challenging. A Taguchi design of experiments (L9 orthogonal array) was employed to assess the effects of nozzle temperature, layer height, printing speed, and extrusion width on dimensional deviation and surface roughness using 5 × 5 × 5 mm cube specimens. Dimensional accuracy was quantified along the horizontal and vertical axes, and surface roughness was measured using a stylus profilometer. Statistical analysis showed layer height was the most significant factor affecting horizontal accuracy (p = 0.0225), while printing speed most strongly influenced vertical deviation. The optimal parameters, 450 °C nozzle temperature, 0.06 mm layer height, 7.5 mm/s printing speed, and 0.4 mm extrusion width, achieved mean deviations of 0.013 mm (horizontal) and 0.049 mm (vertical) with a surface roughness of 4.01 µm. Validation using a benchmark model and micro-computed tomography confirmed improved reproduction of small features under these conditions. The results demonstrate that precise control of FDM parameters enables accurate fabrication of sub-millimeter PEEK structures suitable for medical device applications.

Introduction Tobacco use is the most significant modifiable risk factor for adverse health outcomes, and early research indicates there are also significant harms associated with vaping. National targets aim to reduce smoking and vaping during pregnancy for Aboriginal and Torres Strait Islander people. While most Aboriginal and Torres Strait Islander people want to quit, cessation is frequently attempted without support, increasing the chance of relapse. Group-based smoking cessation programmes increase quit success by 50%–130% in the general population; however, they have never been evaluated in Aboriginal and/or Torres Strait Islander communities. Methods and analysis The Gulibaa study is an Indigenous-led and community-embedded project that will co-design, implement and evaluate a group-based model of care to support Aboriginal and Torres Strait Islander women to be smoke- and vape-free. Staff of Health Services in New South Wales, Australia, will receive training to deliver a face-to-face group-based smoking and vaping cessation intervention. Aboriginal and/or Torres Strait Islander people who identify as a woman or non-binary, are pregnant or of reproductive age (16 to 49 years), currently smoke or vape at least once per day and are willing to attend the programme are eligible to participate. Up to 500 participants will be recruited. A mixed method evaluation approach will be implemented guided by the RE-AIM framework. Outcomes will include intervention reach, intervention effectiveness (determined primarily by self-reported 7-day point prevalence abstinence at 6 months follow-up), acceptability and feasibility of the intervention, programme fidelity and maintenance and cost effectiveness. Ethics and dissemination Embedding culturally safe support to quit during pregnancy can result in improved outcomes for both mother and child and immediately improve intergenerational health and well-being. Ethics approval has been provided by the Aboriginal Health and Medical Research Council and the University of Newcastle. Study findings will be disseminated to Aboriginal and Torres Strait Islander communities in ways that are meaningful to them, as well as through Aboriginal health services, key national bodies, relevant state and federal government departments.

Key Points Contemporary aspirin exacerbated respiratory disorder (AERD) therapy commonly includes aspirin desensitization (55%) and biologics (48%). Aspirin desensitization therapy has higher discontinuation rates than biologics. Patients receiving biologics are younger, and ∼25% of the patients switch to other agents.

ABSTRACT Objectives To review septal perforation management and outcomes in patients with hereditary hemorrhagic telangiectasia (HHT). Methods Collection and presentation of patient demographic, perforation size, and prior perforation and HHT treatment data over a 20‐year period. Symptom and quality of life treatment outcomes were determined using the Nasal Obstruction Symptom Evaluation (NOSE)‐Perf scale and the 5‐Factor Glasgow Inventory (GBI‐5F), respectively, in patients treated since 2017. Results Nine patients met study criteria. Mean (range) age was 64.4 (52–80) years and seven were biological males. Mean (range) perforation length and height were 1.9 (1.2–2.6) and 1.4 (1.0–1.8) cm. Four patients were treated with a customized septal button, one with posterior septal resection, and four with endonasal bilateral mucosal flap repair supported with an interposition graft. The button prostheses were well tolerated and the surgical closures successful at 8–60 months postoperatively. Subjective responses in the first three patients, and NOSE‐Perf with GBI‐5F scores in the latter six patients, demonstrated symptom and quality of life improvement for all patients. Perforation repair patients demonstrated substantial improvement in mean GBI‐5F subdomain scores for quality of life, self‐confidence, and social involvement and all have undergone sodium tetradecyl sclerotherapy injection postoperatively without re‐perforation. Conclusion Symptom and quality of life improvement can be achieved in HHT patients with a perforation using customized septal buttons, posterior septal resection, or bilateral flap surgical repair. Surgical closure combined with injection sclerotherapy is feasible with a low risk of re‐perforation and represents an effective treatment strategy in selected patients. Level of Evidence 4.
