Significance of the Topic:
The study of sensory processing in autism spectrum disorder (ASD) is crucial due to its impact on an individual's quality of life. Up to 95% of autistic individuals experience sensory processing differences, which can lead to difficulties in social interactions, communication, and daily functioning. Understanding the complex relationship between hyper- and hyporesponsivity to sensory stimuli in ASD can provide valuable insights into the neural mechanisms underlying this condition.
Importance:
The study's findings have significant implications for the diagnosis, management, and treatment of ASD. By acknowledging the co-occurrence of hyper- and hyporesponsivity, clinicians can develop more comprehensive and targeted interventions that address the individual's unique sensory processing needs. This can improve the quality of life for autistic individuals and their families.
Timeliness:
The study's focus on the complex relationship between sensory hyper- and hyporesponsivity in ASD is especially timely. Recent advances in neuroimaging and computational modeling have enabled researchers to better understand the neural mechanisms underlying sensory processing. This study contributes to the growing body of research in this area, providing new insights that can inform the development of effective treatments and interventions.
Relevance:
The study's findings have relevance beyond ASD, as they may also apply to a broader range of neurological, psychiatric, and developmental conditions characterized by sensory processing difficulties. The "Sensory Paradox" framework proposed by the study offers a new perspective on sensory processing, which can be applied to various conditions, including ADHD, anxiety disorders, and intellectual disabilities.

BackgroundFirstly, to determine whether iron-sensitive MRI measures mediate neuromelanin (NM) loss within the substantia nigra pars compacta (SNc) and its subregion, nigrosome-1 (N1) in idiopathic Parkinsons disease (iPD) and GBA-associated Parkinsons disease (GBA-PD) versus healthy controls (HC). Secondly, to assess the diagnostic value of NM-and iron MRI metrics, including their lateralisation.
MethodsEighty-six participants (HC=30, iPD = 30, GBA-PD = 26) underwent midbrain quantitative NM-MRI and susceptibility-weighted imaging (SWI). Contrast ratio (CR), normalised volume (nVol) and left-right asymmetry indices (AI) of SNc and N1 calculated. Receiver-operating analyses assessed group discrimination and onset-side prediction. Bidirectional causal mediation (5,000 bootstraps, FDR-corrected) tested Iron[->]NM[->]group and NM[->]Iron[->]group pathways. Moderation models examined the effect of GBA-mutation severity.
ResultsiPD and GBA-PD showed marked NM loss and increased iron in SNc/N1, being more prominent in GBA-PD. N1 NM metrics provided the strongest discrimination (HC vs GBA-PD AUC=0.93, HC vs iPD AUC=0.83), followed by iron measures (AUC=0.78-0.89). N1 NM asymmetry yielded moderate lateralisation accuracy (AUC=0.76). Cross-sectional mediation analyses identified significant Iron[->]NM[->]group effects across SNc and N1 (q<0.01), supporting mechanistic hypotheses of iron-driven NM depletion in PD. In GBA-PD, NM-iron coupling in N1 was influenced by mutation severity, suggesting a genotype-specific disruption of NM-iron homeostasis.
ConclusionsMulti-contrast MRI centered on N1 reveals an iron-driven NM imbalance that distinguishes PD from controls and it is modulated by GBA mutation severity, supporting the applicability of N1-focused NM-iron imaging as a biomarker for PD diagnosis.

IntroductionFor more than two decades, the standard for thrombolysis for Acute Ischemic Stroke (AIS) has been alteplase 0.9 mg/kg (maximum 90 mg) with 10 % given as a bolus. More recent studies such as the EXTEND-IA, and AcT study have shown tenecteplase (TNK) may have potential advantages over alteplase for AIS. In November 2024 the ATTEST-2 study was published with the largest comparative prospective study to date. This study included 1858 patients from 39 stroke centers in the UK which were randomized to receive TNK 0.25 mg/kg IV or alteplase standard of care dose. The study showed TNK was non-inferior to alteplase for 90-day mRS (p<0.001). On March 3rd, 2025, the FDA approved TNK for AIS based off the AcT trial. This study further evaluates the effectiveness and safety of TNK at 0.25 mg/kg IV for AIS and represents real world community hospital utilization covering a diverse population reinforcing the safety and efficacy of TNK compared with alteplase.
MethodsThe analysis used a multicenter, retrospective cohort study across 11 primary and comprehensive hospitals within the BayCare Health System in West Central Florida (December 2019-April 2024), comparing TNK 0.25 mg/kg (max 25 mg) with standard-dose alteplase among adults with AIS presenting within 4.5 hours of last-known-well. The primary outcome (LVO subgroup) was substantial early reperfusion prior to thrombectomy (mTICI 2b/2c/3 or absence of retrievable thrombus). Key secondary outcomes included door-to-needle time, admission, and discharge NIHSS and 90-day mRS, and safety (ICH, angioedema). Adjusted analyses used logistic and ordinal logistic regression.
ResultsAmong 476 AIS patients (TNK n=270; alteplase n=206), 226 had LVO (TNK n=115; alteplase n=111). Early reperfusion occurred in 14.8% with TNK vs 4.5% with alteplase (risk difference 10.3% [95% CI, 2.7-17.8], p=0.008). Adjusted odds of early reperfusion were higher with TNK (OR 3.53 [95% CI, 1.20-10.40], p=0.022). In all AIS patients, median door-to-needle time was shorter with TNK (34 vs 45 minutes; difference -11 [95% CI, -14.4 to -7.6], p<0.001). Good 90-day functional outcome (mRS 0-2) was more common with TNK among LVO patients (47.3% vs 29.3%, p=0.031) and among all AIS patients (61.8% vs 50.0%, difference 11.8% [95% CI, -0.3 to 23.4], p=0.044). Symptomatic ICH and angioedema were similar; across all patients combined, ICH (symptomatic and asymptomatic) was less frequent with TNK (8.5% vs 15.0%, p=0.030).
ConclusionIn routine practice, TNK 0.25 mg/kg was associated with higher pre-thrombectomy reperfusion in LVO, shorter door-to-needle times, comparable safety, and improved functional outcomes versus alteplase in key analyses. These findings align with recent randomized evidence and support TNK as an effective alternative to alteplase for AIS.
