Injury to the hamate can result in significant functional impairment and a negative impact on quality of life. These injuries, in general, occur very infrequently, and in the setting of an increasingly ageing population and more patients presenting post falls, clinicians are at risk of either misdiagnosing or failing to diagnose patients who sustain hamate fractures. This review finds that hamate fractures can occur through acute trauma or chronic repetitive stress.

Van Neck-Odelberg disease (VND) is a term used to describe ischiopubic osteochondritis, which typically presents with atraumatic unilateral groin pain. We performed a systematic review of the existing literature on reported cases of VND to collate what is already known. We also present a new case of VND to add to the relatively small body of literature on the topic.

Protonic ceramic fuel cells (PCFCs) offer a promising, clean, and efficient energy conversion solution. However, thermal mismatch between cathodes and electrolytes remains a critical obstacle, leading to interfacial damage such as cracking and delamination. Incorporating negative thermal expansion (NTE) materials into the cathode can mitigate this issue.

Torus fractures are a common paediatric injury involving the distal radius. Patients typically present following a fall onto the outstretched hand, with wrist pain as their primary complaint. The principal investigation of choice is a plain radiograph of the wrist joint.

Continuous ergonomic risk assessment of the human body is critical to avoid various musculoskeletal disorders (MSDs) for people involved in physical jobs. This paper presents a digital upper limb assessment (DULA) system that automatically performs rapid upper limb assessment (RULA) in real-time for the timely intervention and prevention of MSDs. While existing approaches require human resources for computing the RULA score, which is highly subjective and untimely, the proposed DULA achieves automatic and objective assessment of musculoskeletal risks using a wireless sensor band embedded with multi-modal sensors.

Background: During the COVID-19 pandemic, there is a global demand for intelligent health surveillance and diagnosis systems for patients with critical conditions, particularly those with severe heart diseases. Sophisticated measurement tools are used in hospitals worldwide to identify serious heart conditions. However, these tools need the face-to-face involvement of healthcare experts to identify cardiac problems.

Article Synopsis
  • * The paper introduces a faster method for feature extraction that reduces computation time, crucial for real-time mobile robot tasks, and adds a new benchmark time metric for performance evaluation.
  • * Experimental results demonstrated that the proposed approach outperforms existing methods in terms of computation time, using standard datasets for both indoor and outdoor testing.

Purpose: Effective and efficient haptic guidance is desirable for tele-operated robotic surgery because it has a potential to enhance surgeon's skills, especially in coronary interventions where surgeon loses both an eye-hand coordination and a direct sight to the organ. This paper proposes a novel haptic guidance procedure-both kinesthetic and cutaneous, which solely depends upon X-ray images, for tele-robotic system that assists an efficient navigation of the guidewire towards the target location during a coronary intervention.

Methods: Proposed methodology requires cardiologists to draw virtual fixtures (VFs) on angiograms as a preoperative procedure.

Objective: This morbidity rate has increased compared to the results of a survey in 2012, which were 16,110 cases of STDs, and 11,141 cases in 2010. This study aimed at determining the relationship between knowledge and personal hygiene and the incidence of sexually transmitted diseases in adolescents at the Community Health Center Talise, Palu.

Methods: This study utilized a case-control study design to assess the relationship between knowledge and personal hygiene and the occurrence of sexually transmitted diseases.

The green production of ammonia, in an electrochemical flow cell under ambient conditions, is a promising way to replace the energy-intensive Haber-Bosch process. In the operation of this flow cell with an alkaline electrolyte, water is produced at the anode but also required as an essential reactant at the cathode for nitrogen reduction. Hence, water from the anode is expected to diffuse through the membrane to the cathode to compensate for the water needed for nitrogen reduction.

Visual tracking and 3D representation of guidewire in fluoroscopic image sequence for beating heart image guided interventions is very challenging task. The degraded image quality due to low dose fluoroscopy further complicates the problem. In this paper a robust guidewire tracking is proposed for mean shift algorithm using integrated colour, texture and depth features.
