Techniques of core decompression in the treatment of idiopathic avascular necrosis of the femoral head.

Core decompression was developed as a joint-preserving procedure for patients with early-stage osteonecrosis of the femoral head. Previous studies indicated a high success rate that outperforms nonoperative management of pre-collapse hips. The traditional single-tunnel core decompression technique uses a cannulated drill bit inserted into the lateral cortex of the proximal femur.

Acute myocardial infarction presenting as headache: a case report.

Background: The diagnosis of acute myocardial infarction is straightforward when it presents with typical symptoms. However, some patients can be asymptomatic, and some can present with atypical symptoms.

Case Presentation: We present a very rare case of acute myocardial infraction that presented with headache and right upper limb numbness of 2-day duration in a 61-year-old female Middle Eastern patient.

Pre-hospital blood pressure lowering in presumed hyperacute stroke: A systematic review and meta-analysis of randomized controlled trials.

Ischemic heart disease awareness in Egypt's aging population: findings from a national cross-sectional study.

Background: Ischemic heart disease (IHD) remains a leading cause of mortality among the elderly population, particularly in low- and middle-income countries like Egypt, where public health infrastructure may struggle to meet the needs of a growing aging population. Awareness of the risk factors and warning signs associated with IHD is critical for early detection and intervention. This study aimed to evaluate the level of awareness and knowledge regarding IHD risk factors and warning signs among elderly individuals in Egypt, focusing on differences between urban and rural populations.

Prediction of primary admission total charges following cervical disc arthroplasty utilizing machine learning.

Background Context: Cervical disc arthroplasty (CDA) has become an increasingly popular alternative to anterior cervical discectomy and fusion, offering benefits such as motion preservation and reduced risk of adjacent segment disease. Despite its advantages, understanding the economic implications associated with varying patient and hospital factors remains critical.

Purpose: To evaluate how hospital size, geographic region, and patient-specific variables influence charges associated with the primary admission period following CDA.

Nuclear Imaging in Orthopaedic Practice: A Critical Analysis Review.

» Nuclear imaging techniques, including bone scintigraphy, labeled leukocyte scintigraphy, positron emission tomography (PET), and single-photon emission computed tomography (SPECT) combined with computed tomography (CT), have wide applications in orthopaedics for evaluating trauma, painful total joint arthroplasty, musculoskeletal infection, and orthopaedic oncology.» Three-phase bone scintigraphy is a first-line, highly sensitive nuclear medicine study for evaluating orthopaedic pathology when initial studies are inconclusive. However, its specificity is limited, and findings may be falsely positive for up to 2 years after total joint arthroplasty because of physiologic bone remodeling.

Evaluation of the Psychiatric Disorders among Amphetamine Addicts in Rehabilitation Centers: A Cross-Sectional Analysis.

Background: People who are addicted to amphetamines have a much greater chance of developing psychosis compared to those who are not. It is essential to study the behavioral and psychological effects of amphetamines. Therefore, this research aimed to examine conditions such as depression, anxiety, mood, cognitive abilities at the workplace, and social responsibilities by using sociodemographic factors as useful tools in determining effective strategies for preventing, managing, and treating amphetamine addiction.

Radiochemical neutron activation analysis of elemental contents in crude phosphoric acid samples and studies on adsorption removal of these elements using synthesized bionanocomposites.

Surgical Management of Chronic Morel-Lavallée Lesion with Minimal Cosmetic Scarring: A Case Report.

Introduction: Morel-Lavallée lesion (MLL) is a closed degloving injury that occurs after traumatic damage to soft tissue, leading to the formation of an encapsulated serosanguinous collection of fluid. Although some MLLs resolve spontaneously, chronic MLLs present with a significant risk of infection and may impede patients' quality of life. Chronic lesions require surgical intervention to evacuate and debride the hematoma, often resulting in severe cosmetic damage postoperatively.

Evaluation of serum levels of sestrin 2 and betatrophin in type 2 diabetic patients with diabetic nephropathy.

Background: Diabetic kidney disease (DKD) is one of the most serious microvascular complications of diabetes mellitus (DM) and the leading cause of chronic kidney disease (CKD) worldwide. Since obesity and type 2 DM (T2DM) are considered as inflammatory conditions, thus reducing their accompanied systemic inflammation may lessen their complications. Sestrin 2 belongs to a group of stress induced proteins which are produced in response to oxidative stress, inflammation and DNA damage.

Knowledge and Utilization of Sex-Specific Lead Aprons Among Pediatric Orthopaedic Surgeons.

Background: Orthopaedic surgeons routinely face exposure to ionizing radiation during intraoperative use of fluoroscopy. Lead personal protective equipment reduces occupational radiation exposure. Female-specific lead aprons are designed with expanded lateral coverage to improve protection of breast tissue against radiation beams.

Wind turbine with line-side PMSG FED DC-DC converter for voltage regulation.

This article represents a novel study of the design and analysis of a wind turbine system that includes a line-side permanent magnet synchronous generator (PMSG) with an ultra-step-up DC-DC converter for voltage regulation. Integrating renewable energy sources such as wind power into the grid requires efficient and reliable power conversion systems to handle fluctuating power and ensure a stable power supply. The wind turbine system utilizes a PMSG, which offers several advantages over traditional induction generators, including higher efficiency, reduced maintenance, and better power quality.

Operative Time Associated With Increased Length of Stay After Single-level Cervical Disk Arthroplasty: An Analysis of 3681 Surgeries.

Study Design: Level III evidence-retrospective cohort.

Objective: The purpose of this study was to (1) determine whether longer CDA operative time increases the risk of 30-day postoperative complications, (2) analyze the association between operative time and subsequent health care utilization, and (3) discharge disposition.

Background: Cervical disk arthroplasty (CDA) most commonly serves as an alternative to anterior cervical discectomy and fusion (ACDF) to treat cervical spine disease, however, with only 1600 CDAs performed annually relative to 132,000 ACDFs, it is a relatively novel procedure.

Clinical value of adding Dapagliflozin in patients with nephrotic syndrome.

Background: Sodium-glucose cotransporter 2 (SGLT2) inhibitors in nephrotic patients on immunosuppression are underexplored. We evaluated dapagliflozin's impact in non-diabetic primary nephrotic syndrome.

Methods: Randomized controlled clinical trial was conducted on 60 non-diabetic primary nephrotic syndrome patients, equally assigned to dapagliflozin and control groups.

Performance analysis of DFIG support microgrid using GA optimized restricted Boltzmann Machine algorithm.

Voltage and reactive power regulation in a deregulated microgrid can be achieved by strategically placing the Static Synchronous Compensator (STATCOM) in coordination with other renewable energy sources, thus ensuring high-end stability and independent control. STATCOM plays a crucial role in effectively addressing power quality issues such as voltage fluctuation and reactive power imbalances caused by the intermittent nature of wind energy conversion systems. To successfully integrate STATCOM into the existing system, it is essential that the control system employed for STATCOM coordination aligns with the Doubly-Fed Induction Generator (DFIG) controller within the microgrid.
