Effective rehabilitation strategies are essential to enhance motor recovery and restore functional independence. This review evaluates the most effective interventions for improving upper extremity function in patients with hemiparesis. A comprehensive literature review was conducted, analyzing systematic reviews, randomized controlled trials, and clinical guidelines. The efficacy of various interventions, including task-specific training, constraint-induced movement therapy (CIMT), neuromuscular electrical stimulation (NMES), mirror therapy, virtual reality, bilateral arm training, pharmacological approaches, and robotic-assisted rehabilitation, was assessed based on their impact on motor function and daily activities. The review highlights the role of neuroplasticity in motor recovery, emphasizing interventions that promote cortical reorganization. Task-specific training, CIMT, and NMES demonstrate strong evidence in enhancing motor function. Emerging technologies, such as brain-computer interfaces and robotics, show promise in optimizing rehabilitation outcomes. Factors influencing recovery, including stroke severity, time since onset, and patient motivation, are discussed. Studies consistently support the effectiveness of CIMT and task-specific training in improving upper extremity function. NMES and mirror therapy are beneficial adjunct therapies, particularly for patients with moderate impairment. Virtual reality and robotics enhance engagement and motor learning, while pharmacological and stem cell therapies are emerging areas with potential but require further research. A multimodal rehabilitation approach combining task-oriented therapies, neuromodulation, and emerging technologies yields the best outcomes for upper extremity recovery in hemiparesis patients.

Within this spectrum, critical congenital heart defects (CCHDs) represent the most severe forms, often necessitating surgical or catheter-based intervention within the first year of life. Delayed or missed diagnosis of CCHDs remains a major cause of preventable neonatal morbidity and mortality, underscoring the importance of timely detection. Pulse oximetry screening has emerged as a noninvasive, inexpensive, and highly specific method to identify hypoxemia, particularly in duct-dependent lesions that may otherwise escape early clinical recognition. Since its universal adoption in the United States in 2011, pulse oximetry screening has consistently demonstrated value as a complementary tool to prenatal ultrasound and physical examination, improving detection rates, reducing emergency hospitalizations, and lowering infant mortality. Despite its proven clinical impact, important challenges remain. Screening sensitivity is limited, especially for conditions such as coarctation of the aorta that may not produce early hypoxemia. Variability in protocols, including timing of screening, pre- versus post-ductal measurement, and thresholds for repeat testing, contributes to inconsistent performance across hospitals. Moreover, recent evidence of racial bias in pulse oximetry accuracy, along with persistent disparities in early detection across demographic groups, highlights the need for inclusive device validation and standardized protocols. In low- and middle-income countries, pilot studies from Rwanda, Nigeria, and India demonstrate feasibility and dual benefits for detecting both cardiac and non-cardiac hypoxemic conditions, but widespread implementation is hindered by resource constraints, inadequate referral pathways, and limited access to confirmatory echocardiography. Emerging strategies, including integration with electronic medical records, computerized clinical decision support systems, and mobile health technologies, hold promise for standardizing workflows, improving compliance, and extending reach to resource-limited settings. This article presents a synthesisis of current evidence on the effectiveness, limitations, and global implementation of pulse oximetry screening for the detection of congenital heart defect detection, highlighting both its established role in neonatal care and the urgent need for innovations to address disparities, optimize protocols, and ensure equitable access to screening worldwide.</p>","PeriodicalId":72523,"journal":{"name":"Cardiology and cardiovascular medicine","volume":"9 5","pages":"444-456"},"PeriodicalIF":0.0,"publicationDate":"2025-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12674206/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145679504","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

These ocular emergencies are closely associated with systemic vascular risk factors, including hypertension, diabetes mellitus, advanced age, and cardiovascular comorbidities. Atrial fibrillation (AFib), the most common sustained cardiac arrhythmia, has emerged as a notable contributor to the risk of retinal artery occlusions. The prevalence of AFib is rising, particularly among older adults, paralleling the age-dependent increase in retinal artery occlusion incidence. Recent studies indicate a significant association between AFib and retinal artery occlusions, with AFib conferring an elevated risk for both retinal and cerebral ischemic events. Notably, Patients with retinal artery occlusion exhibit a heightened risk of subsequent AFib, stroke, and thromboembolic complications. The pathophysiological interplay involves embolic phenomena originating from cardiac or carotid sources, with AFib facilitating thrombus formation and embolization to the retinal circulation. Diagnostic advances, including prolonged cardiac monitoring and optical coherence tomography, have improved detection of both AFib and retinal ischemic changes. Despite the lack of a universally accepted treatment for retinal artery occlusions, early interventions such as thrombolysis and hyperbaric oxygen therapy may improve visual outcomes if administered promptly. This manuscript underscores the importance of comprehensive cardiovascular evaluation in patients with retinal artery occlusion, particularly for AFib, to optimize risk stratification, guide management, and reduce the likelihood of recurrent vascular events.
