The objectives of this study were to establish the prevalence and infection-free implant survival in UPCs during presumed aseptic single-stage revision THA and TKA at mid-term follow-up.

Methods: This study included 297 patients undergoing presumed aseptic single-stage revision THA or TKA at a single treatment centre.

Interpretation of Ferritin Concentrations in the Dermatology Clinic.

Ferritin is a commonly measured laboratory test in dermatology. It is a marker of iron storage in the human body but also elevated in inflammatory states. Changes in ferritin are therefore non-specific and correlation of specific clinical findings and risk factors with ferritin concentration and other biomarkers e.

Beta-Blockers as an Immunologic and Autonomic Manipulator in Critically Ill Patients: A Review of the Recent Literature.

The autonomic nervous system plays a key role in maintaining body hemostasis through both the sympathetic and parasympathetic nervous systems. Sympathetic overstimulation as a reflex to multiple pathologies, such as septic shock, brain injury, cardiogenic shock, and cardiac arrest, could be harmful and lead to autonomic and immunologic dysfunction. The continuous stimulation of the beta receptors on immune cells has an inhibitory effect on these cells and may lead to immunologic dysfunction through enhancing the production of anti-inflammatory cytokines, such as interleukin-10 (IL-10), and inhibiting the production of pro-inflammatory factors, such as interleukin-1B IL-1B and tissue necrotizing factor-alpha (TNF-alpha).

Is there sufficient evidence to support the use of antibiotic holiday just before the second stage of an infected total hip or knee arthroplasty revision surgery?

The practice of implementing an antibiotic holiday before the second stage of hip or knee arthroplasty is currently controversial due to limited evidence for this approach, as per the International Consensus Meeting 2018 on Musculoskeletal Infection. A greater understanding of this issue could augment the quality of Alrayes and Sukeik's mini-review (2023) on diagnosing, managing, and treating periprosthetic knee infections. However, a significant lack of literature exists concerning the optimal duration for the antibiotic holiday, calling for more research before establishing any clinical guidelines.

Establishing and Monitoring an Effective Management of Benign Nontoxic Multinodular Goitre in Kuwait "Utilizing Two Different Dose Levels of Recombinant Human TSH in Combination with Radioactive Iodine".

Introduction: rhTSH-assisted radioiodine therapy of multinodular goiter is not fully known and only a few studies, with a limited number of patients have evaluated the effect of rhTSH assisted radioiodine therapy beyond 1 year. Though there is an effective and safe management of benign non-toxic MNG available, it is not applicable to all patient categories in Kuwait covering the impact of the past environmental events (Gulf War) and the genetic relation. The proposed project aims to address those points raised, that is exclusive to the Kuwait population.

Statin-induced, immune-mediated necrotising myopathy triggered by malignancy successfully treated with immunosuppression.

Statin-induced immune-mediated necrotising myopathy (IMNM) is an inflammatory myopathy that can present as proximal muscle weakness and, in some cases, as dysphagia and respiratory distress. In this report, we present a case of statin-induced IMNM in a 78-year-old male. The patient had significantly high levels of creatinine kinase and myoglobinuria and experienced gradual weakness in the proximal muscles for 1 month after initiating a 20 mg dose of Atorvastatin 10 months before admission.

A review of the American College of Surgeons accredited education institutes' assessment practices for learners, faculty, and continuous program improvement.

Purpose: Simulation is an instructional modality that offers opportunities for assessment across many domains. The American College of Surgeons created the Accredited Education Institutes (AEIs) to build a community of high-quality simulation centers focused around improving surgical education and training. The goals of this project were to identify assessment methods used by AEIs, discuss how these methods align with established assessment frameworks, identify best practices, and provide guidance on best practice implementation.

What makes a multidisciplinary medication review and deprescribing intervention for older people work well in primary care? A realist review and synthesis.

Background: A third of older people take five or more regular medications (polypharmacy). Conducting medication reviews in primary care is key to identify and reduce/ stop inappropriate medications (deprescribing). Recent recommendations for effective deprescribing include shared-decision making and a multidisciplinary approach.

Pharmacological treatment of gastro-oesophageal reflux in children.

Background: Gastro-oesophageal reflux (GOR) is characterised by the regurgitation of gastric contents into the oesophagus. GOR is a common presentation in infancy, both in primary and secondary care, affecting approximately 50% of infants under three months old. The natural history of GOR in infancy is generally of a self-limiting condition that improves with age, but older children and children with co-existing medical conditions can have more protracted symptoms.

Understanding the role of intimate partner violence on HIV transmission in Zimbabwe: Secondary data analysis of data from the Zimbabwe demographic survey 2015-2016.

Background: Gender-based violence (GBV) has been shown to have significant and long-lasting impacts on women's physical and mental health. It is, therefore, important to study its occurrence in a population and its intersect with infectious diseases such as HIV to inform the wider health promotion agenda. This study aimed to determine the association between GBV and HIV status in women and adolescent girls in Zimbabwe.

International Delphi Consensus Study on disposable single-use endoscopy: A path to clinical adoption.

Background/objective: Increasing infectious rate estimates and low microbiological surveillance affect safety of gastrointestinal endoscopy globally. Single use endoscopes and accessories have been claimed to improve safety, but there is lack of data on their indication and sustainability. We aimed to identify a series of best practice recommendations for the use of single use endoscopes and accessories using a modified Delphi.

A prospective multicentre observational study to quantify nocturnal light exposure in intensive care.

Background: Disrupted circadian rhythms can have a major effect on human physiology and healthcare outcomes, with proven increases in ICU morbidity, mortality and length of stay.

Methods: We performed a multicentre observational study to study the nocturnal lux exposure of patients in 3 intensive care units.

Results: The median light intensity recorded was 1 lux over the 6-hour recording period; however, this is deceptive as it hides short periods of high lux.

Role extension in advanced ultrasound practice: A framework approach and case study.

Introduction: Role extension into novel areas of ultrasound practice can be challenging for health care professionals. Expansion into existing areas of advanced practice typically occurs using established processes and accredited training; however, in areas where there is no formal training, there can be a lack of support for how to develop new and progressive clinical roles.

Topic Description: This article presents how the use of a framework approach for establishing areas of advanced practice can support individuals and departments with safely and successfully developing new roles in ultrasound.

Differential effects of high-altitude exposure on markers of oxidative stress, antioxidant capacity, and iron profiles.

High-altitude (HA) exposure may stimulate significant physiological and molecular changes, resulting in HA-related illnesses. HA may impact oxidative stress, antioxidant capacity, and iron homeostasis, yet it is unclear how both repeated exposure and HA acclimatization may modulate such effects. Therefore, we assessed the effects of weeklong repeated daily HA exposure (2,900-5,050 m) in altitude-naïve individuals ( = 21 individuals, 13 females, mean ± SD, 25.
