The coronavirus disease clavicle study: a predictor of future trauma trends.

Background: Clavicle fractures are a common presentation to the emergency department after falls and sporting injuries. During 2020, the coronavirus disease 2019 (COVID-19) pandemic brought with it a long period of social isolation, resulting in a change of behavior patterns and, in return, the presentation of fractures to our local hospitals. The effects of this global pandemic on the presentation and management of clavicles were noted with particular interest to the change in mechanism and its future implications.

Radiographic vs. MRI vs. arthroscopic assessment and grading of knee osteoarthritis - are we using appropriate imaging?

Purpose: Radiographs and MRI scans are commonly used imaging techniques in the assessment of knee osteoarthritis. However, it currently remains uncertain how good a representation of the actual condition of the knee joint these investigations provide. By comparing them against arthroscopic findings the aim of our study was to conclude how accurate these imaging techniques are at grading knee osteoarthritis.

Changing to Removable Casts During the Coronavirus Pandemic-Has It Affected Outcomes for Distal Radius Fractures?

BOAST (British Orthopaedic Association Standards for Trauma & Orthopaedics) guidelines recommended that during the coronavirus pandemic most upper limb fractures should be treated conservatively, and removable casts should be used, where possible. As a result, our district general hospital started using a new soft combination (soft-combi) casting technique for conservative management of distal radius fractures (DRFs) in an attempt to reduce follow-up attendances. To assess if radiological outcomes of soft-combi casts are better or worse than previously used rigid casts for DRFs.

Telemedicine with clinical decision support for critical care: a systematic review.

Background: Telemedicine applications aim to address variance in clinical outcomes and increase access to specialist expertise. Despite widespread implementation, there is little robust evidence about cost-effectiveness, clinical benefits, and impact on quality and safety of critical care telemedicine. The primary objective was to determine the impact of critical care telemedicine (with clinical decision support available 24/7) on intensive care unit (ICU) and hospital mortality and length of stay in adults and children.

Dietary zinc reduces osteoclast resorption activities and increases markers of osteoblast differentiation, matrix maturation, and mineralization in the long bones of growing rats.

The nutritional influence of zinc on markers of bone extracellular matrix resorption and mineralization was investigated in growing rats. Thirty male weanling rats were randomly assigned to consume AIN-93G based diets containing 2.5, 5, 7.

Hearts in adult offspring of copper-deficient dams exhibit decreased cytochrome c oxidase activity, increased mitochondrial hydrogen peroxide generation and enhanced formation of intracellular residual bodies.

The long-term effects of low dietary copper (Cu) intake during pregnancy and lactation on cardiac mitochondria in first-generation adult rats was examined. Rat dams were fed diets containing either low (1 mg/kg Cu) or adequate (6 mg/kg Cu) levels of dietary Cu beginning 3 weeks before conception and ending 3 weeks after birth. Cytochrome c oxidase (CCO) activity was 51% lower in isolated cardiac mitochondria from 21-day-old offspring of Cu-deficient dams than in the offspring of Cu-adequate dams.

Manganese alters mitochodrial integrity in the hearts of swine marginally deficient in magnesium.

It was previously reported that pigs marginally deficient in magnesium (Mg) and fed diets high in manganese (Mn) died suddenly with signs of sudden cardiac death. Manganese, which has properties similar to Mg, may exacerbate Mg-deficiency and be accumulated by mitochondria resulting in ultrastructural damage. The objective of this study was to determine whether deaths of the type previously observed were mediated by adverse interactions of Mn and Mg resulting in ultrastructural damage to the myocardium, alterations in electrocardiographic recordings and tissue retention of Mn, Mg and calcium (Ca).

Primary, extranodal, follicular non-Hodgkin lymphoma of the gallbladder: case report and a review of the literature.

We report the first case of isolated primary extranodal non-Hodgkin lymphoma follicular grade 2 limited to the gallbladder, found in the laparoscopic cholecystectomy specimen from a 70 year old woman with symptomatic cholelithiasis. The pericystic duct lymph node, surgical margins, and other lymph nodes, were not involved with lymphoma. According to the medical literature in English language, mucosa associated lymphoid tissue lymphoma (6 cases) is the most frequent type (38%) of primary gallbladder lymphomas (15 reported cases plus our case).

Bioavailability of elemental iron powders to rats is less than bakery-grade ferrous sulfate and predicted by iron solubility and particle surface area.

Foods are fortified with elemental forms of iron to reduce iron deficiency. However, the nutritional efficacy of current, commercially produced elemental iron powders has not been verified. We determined the bioavailability of six commercial elemental iron powders and examined how physicochemistry influences bioavailability.

Copper deficiency: A potential model for determining the role of mitochondria in cardiac aging.

Heart mitochondria experience age-related declines in cytochrome c oxidase (CCO) activity and increases in the generation of reactive oxygen species (ROS) that may contribute to loss of cardiac function and the development of disease that occur with advancing age. In a manner similar to aging, copper deficiency also suppresses heart CCO activity and has cardiovascular consequences related to increased peroxidation. Food restriction is often used as a tool to study oxidative mechanisms of aging and the present study examines the potential of copper deficiency to model the role of mitochondria in cardiac aging by determining if the effect of food restriction on CCO activity and oxidative stress in heart mitochondria parallels its effect on cardiac mitochondria during aging.
