There is a worldwide trend toward 'revisiting' cemented total hip arthroplasty (THA). In Japan, however, cemented THAs accounts for 11%, and the percentage of cemented hemiarthroplasty is estimated to be less than 10%. This review was designed to reconsider the option of cemented THA and to encourage policy changes in Japan to support the best possible care for patients.

The Mobi-C Cervical Disc Replacement is a motion preserving alternative to anterior cervical discectomy and fusion in properly indicated patients. In 2013, Mobi-C became the first cervical disc in the United States approved to treat more than one level of the cervical spine. The FDA determined Mobi-C to be statistically superior to fusion at two levels, based on the primary endpoint of a prospective, concurrently controlled and randomized multicenter clinical trial.

To explore the impact of glaucoma on the retinal nerve fiber layer (RNFL) optical density ratio (ODR) by volumetric optical coherence tomography (OCT) under different analytical radii.

The China National Medical Product Administration (NMPA), European Commission, and United States Food and Drug Administration (FDA) follow similar principles to establish regulatory requirements for medical device clinical evaluations throughout the total product lifecycle (TPLC). However, critical differences in these requirements may have led to different regulatory clinical evaluation strategies in the three jurisdictions. A thorough understanding of these differences is crucial for developing effective global regulatory strategies.

Since the mid-1900s, techniques in the repair of aortic arch and thoracoabdominal aortic pathologies have drastically evolved. Open aortic surgical repair was once the sole option for both simple and complex aneurysmal degeneration. Today, a number of minimally invasive and hybrid approaches are now available to assist both the surgeon and patient in tackling this challenging problem.

In patients with symptomatic, refractory atrial fibrillation the ablate and pace (A&P) strategy (pacemaker implantation followed by atrio-ventricular junction ablation (AVJA)) is superior to medical therapy in improving quality of life and prognosis. Despite its well-proven benefits, this invasive therapeutic option is still underutilized in clinical practice. The choice of pacing modality (right ventricular pacing, biventricular pacing, BVP, or conduction system pacing, CSP) is crucial and can have significant clinical implications. In particular, in recent years CSP is emerging as an alternative to BVP, showing a good effectiveness and safety profile. Other important aspects are the timing of ablation, the approach used for AVJA, and the correct device programming after AVJA.

This comparative study examines the complexities of adverse event reporting forms for medical devices across various nations. Despite rigorous clinical trials and surveillance techniques, variations persist in processes and data elements used to report adverse events. The study highlights the importance of standardizing adverse event reporting for medical devices and suggests a comprehensive 'Generic Adverse Event Reporting Form' to accurately determine causality. The advice encourages widespread use of this generic form to create a standardized and effective system for reporting adverse events related to medical devices.

Wearables are electronic devices worn on the body to collect health data. These devices, like smartwatches and patches, use sensors to gather information on various health parameters. This review highlights the current use and the potential benefit of wearable technology in patients with inflammatory bowel disease (IBD).

Fast-acting Sub-perception Therapy (FAST) is a novel spinal cord stimulation (SCS) modality delivering paresthesia-free pain relief. Our study evaluated the longer-term, real-world impact of FAST on chronic pain.

Cardiac stents are utilized to treat coronary artery diseases, a leading cause of death worldwide including in India. We investigated frequency and nature of adverse events (AEs) associated with cardiac stents in the Indian population.

Proactive esophageal cooling reduces injury during radiofrequency (RF) ablation of the left atrium (LA) for the treatment of atrial fibrillation (AF). New catheters are capable of higher wattage settings up to 90 W (very high-power short duration, vHPSD) for 4 s. Varying power and duration, however, does not eliminate the risk of thermal injury. Furthermore, alternative energy sources such as pulsed field ablation (PFA) also exhibit thermal effects, with clinical data showing esophageal temperatures up to 40.3°C. The ensoETM esophageal cooling device (Attune Medical, now a part of Haemonetics, Boston, MA, U.S.A.) is commercially available and FDA-cleared to reduce thermal injury to the esophagus during RF ablation for AF and is recommended in the 2024 expert consensus statement on catheter and surgical ablation of AF.

Amblyopia, the leading cause of monocular childhood vision loss, affects millions and is projected to increase. Early detection and treatment are crucial for preventing vision impairment.

Digital therapeutics (DTx) are an emerging phenomenon within the scientific landscape which is attracting considerable international interest. This review aimed to provide an overview of the definition and classification of DTx, focusing on the contribution that DTx may provide in the treatment of a lot of diseases, compared with pharmacological treatments and highlighting it strengthens and weaknesses into the European regulatory landscape.

The average body mass index (BMI) in the United States has tripled over the last five decades despite concerted population-based efforts for weight management. Elevated BMI and, in particular, obesity are risk factors for osteoarthritis. This trend has led to increased demands for total knee (TKA) and total hip arthroplasty (THA), necessitating an in-depth understanding of how elevated BMI impacts TKA and THA.

Smartphone electrocardiograms (iECGs) are an innovative method of capturing transient arrhythmias that are occasionally experienced by athletes. This study aimed to assess the accuracy of a 6-lead iECG compared with 12-lead ECG in athletes and those with known genetic heart disease (positive controls).

Recently, there has been growing experience with utilizing a veno-arterial extracorporeal membrane oxygenator (VA ECMO) routinely during lung transplantation procedures. Yet, there is a lack of consensus on the protocols, benefits, and outcomes of routine VA ECMO use in lung transplantation.

Out-of-hospital cardiac arrest (OHCA) is characterized by the cessation of mechanical cardiac activity and voluntary circulation occurring outside of a hospital setting, making it the leading cause of death worldwide. Recently, the optimal approach to airway management has been a subject of controversy.
