BACKGROUND: Limited evidence exists for meniscal repair outcomes in a multiligament reconstruction setting. Purpose/Hypothesis: The purpose of this study was to assess outcomes and failure rates of meniscal repair in patients who underwent multiligament reconstruction compared with patients who underwent multiligament reconstruction but lacked meniscal tears. The authors hypothesized that the outcomes of meniscal repair associated with concomitant multiligament reconstruction would significantly improve from preoperatively to postoperatively at a minimum of 2 years after the index surgery...

Vitamin D has a range of non-skeletal health effects and has been implicated in the response to respiratory infections. The aim of this study was to assess the effect of vitamin D on the response of epithelial cells, neutrophils and macrophages to lipopolysaccharide (LPS) stimulation. BEAS-2B cells (airway epithelial cell line) and primary neutrophils and macrophages isolated from blood samples were cultured and exposed to LPS with and without vitamin D (1,25(OH)2D). The production of IL-6, IL-8, IL-1β and TNF-α of all cells and the phagocytic capacity of neutrophils and macrophages to E...

Objective: Correct assessment of patient urgency is critical to ensuring patient safety in emergency departments (EDs). Although significant time and effort have been devoted to developing triage systems, less attention has been paid to the development of quality control. The aim of this study is to introduce and test observation technique, which enables identifying of patient groups at risk of erroneous assessment in triage. The introduced technique is aimed to be less laborious to use than existing triage quality control methods...

Staphylococcus aureus are globally disseminated among farmed chickens causing skeletal muscle infections, dermatitis and septicaemia. The emergence of poultry-associated lineages has involved zoonotic transmission from humans to chickens but questions remain about the specific adaptations that promote proliferation of chicken pathogens. We characterised genetic variation in a population of genome-sequenced S. aureus isolates of poultry and human origin. Genealogical analysis identified a dominant poultry-associated sequence cluster within the CC5 clonal complex...

Piscine orthoreovirus (PRV) is ubiquitous in farmed Atlantic salmon (Salmo salar) and the cause of heart and skeletal muscle inflammation. Erythrocytes are important target cells for PRV. We have investigated the kinetics of PRV infection in salmon blood cells. The findings indicate that PRV causes an acute infection of blood cells lasting 1-2 weeks, before it subsides into persistence. A high production of viral proteins occurred initially in the acute phase which significantly correlated with antiviral gene transcription...

Air pollution has been a major environment-related health threat. Most of the studies on PM2.5 toxicity have verified on the cardiovascular system and endothelial cells. However, researches on PM2.5-induced myocardial-related toxicity are limited. This study aims to fully understand the toxic effects of PM2.5 on human myocardial cell (AC16) and explore its molecular mechanism based on microarray analysis and bioinformatics analysis. Microarray data analysis manifested that PM2.5-induced toxicity affected expression of 472 genes compared with the control group, including 166 upregulated genes and 306 downregulated genes in human myocardial (AC16) cells...

Heart and skeletal muscle inflammation (HSMI) and pancreas disease (PD) cause substantial losses in Atlantic salmon (Salmo salar) aquaculture. The respective causative agents, Piscine orthoreovirus (PRV) and Salmonid alphavirus (SAV), are widespread and often concurrently present in farmed salmon. An experimental infection in Atlantic salmon was conducted to study the interaction between the two viruses, including the immunological mechanisms involved. The co-infected fish were infected with PRV four or ten weeks before they were infected with SAV...

COMPARATIVE STUDY
Thomas C Michels, Keith E Petersen
Multiple myeloma accounts for 1.6% of all cancer cases and approximately 10% of hematologic malignancies in the United States. In 2015, an estimated 28,850 new cases of multiple myeloma were diagnosed in the United States, and the disease caused more than 11,000 deaths. Patients older than 65 years account for 85% of those diagnosed with multiple myeloma, and there is a twofold increased incidence in blacks compared with whites. Patients may present with bone pain or with symptoms that are often nonspecific, such as nausea, vomiting, malaise, weakness, recurrent infections, and weight loss...

BACKGROUND: Menkes disease (MD) is an X-linked recessive neurodegenerative disorder caused by mutations in ATP7A gene. Depending on the residual ATP7A activity, manifestation may be classical MD, occipital horn syndrome, or distal motor neuropathy. Neurological sparing is expected in female carriers. However, on rare occasions, females may manifest with classical clinical phenotype due to skewed X-chromosome inactivation, X-autosome translocation, and XO genotype. Here, we describe a small series of probands with MD and their response to copper histidine therapy...

Involvement of the musculoskeletal system by primary or metastatic malignant neoplasms mimicking common orthopaedic conditions is well recognized. The diagnosis may be delayed in the absence of radiographic abnormalities. Twenty-five percent of lymphoma cases have skeletal involvement, and they can affect both bone and soft tissue. Lymphoma is sometimes discovered by means of routine histologic examination of tissue collected at the time of orthopaedic surgery. To the best of our knowledge, this is the first report of lymphoma occurring at the site of prior shoulder surgery and mimicking an infection...

Skeletal muscle in mammals can express and secrete immune-related molecules during pathogen infection. Despite in fish is known that classical immune tissues participate in innate immunity, the role of skeletal muscle in this function is poorly understood. To determine the immunocompetence of fish skeletal muscle, juvenile fine flounder (Paralichthys adpersus) were challenged with Vibrio ordalii. Different Toll-like receptors, pro-inflammatory cytokines (TNFα, Il-1β, and IL-8), and immune-effector molecules (NKEF and the antimicrobial peptides hepcidin and LEAP-2) were analyzed...

Gestational diabetes mellitus (GDM), which complicates up to 20% of all pregnancies, is associated with low-grade maternal inflammation and peripheral insulin resistance. Sterile inflammation and infection are key mediators of this inflammation and peripheral insulin resistance. Resveratrol, a stilbene-type phytophenol, has been implicated to exert beneficial properties including potent anti-inflammatory and antidiabetic effects in non-pregnant humans and experimental animal models of GDM. However, studies showing the effects of resveratrol on inflammation and insulin resistance associated with GDM in human tissues have been limited...

Future growth in aquaculture relies strongly on the control of diseases and pathogens. Vaccination has been a successful strategy for obtaining control of bacterial diseases in fish, but for viral diseases, vaccine development has been more challenging. Effective long-term protection against viral infections is not yet fully understood for fish, and in addition, optimal tools to monitor adaptive immunity are limited. Assays that can detect specific antibodies produced in response to viral infection in fish are still in their early development...

Hand, foot and mouth disease (HFMD) is a global health concern. Family Picornaviridae members, particularly enterovirus 71 (EVA71) and Coxsackievirus A16 (CVA16), are the primary etiological agents of HFMD, however, a third enterovirus A species, CoxsackievirusA6 (CVA6), has been recently associated with epidemic outbreaks. Study of the pathogenesis of CVA6 infection and development of antivirals and vaccines are hindered due to the lack of appropriate animal models. We have developed and characterized a murine model of CVA6 infection which was employed to evaluate the antiviral activities of different drugs and the protective efficacies of CVA6-inactivated vaccines...

Intramedullary, bone-anchored (osseointegrated), transcutaneous docking of artificial limbs has been in clinical use for more than 25 years. This system of prosthetic limb attachment is a valuable treatment option in the rehabilitation of patients after limb amputation. Only a few centers are systematically investigating this topic worldwide so that current knowledge on this special treatment option is still limited; however, mainstream medical opinion still regards percutaneous skeletal prosthetic docking with some skepticism...

Heart and skeletal muscle inflammation (HSMI) is an emerging disease of marine-farmed Atlantic Salmon (Salmo salar), first recognized in 1999 in Norway, and later also reported in Scotland and Chile. We undertook a longitudinal study involving health evaluation over an entire marine production cycle on one salmon farm in British Columbia (Canada). In previous production cycles at this farm site and others in the vicinity, cardiac lesions not linked to a specific infectious agent or disease were identified. Histologic assessments of both live and moribund fish samples collected at the farm during the longitudinal study documented at the population level the development, peak, and recovery phases of HSMI...

The authors describe the first case of tooth extraction in a patient treated with autologous skeletal myocardial sheet transplantation for severe dilated cardiomyopathy. This condition is associated with significant morbidity and mortality that may have identifiable causes or may be idiopathic or inherited. In addition to local disinfection, antimicrobial prophylaxis and continuous anticoagulant therapy during the perioperative period of tooth extraction were needed to prevent infective endocarditis and ensure the success of regenerative therapy of the heart...

Non-pharmacological strategies have been rarely described in the treatment of infectious diseases. Although exercise training has been recently incorporated in the clinical management of Chagas disease, the rationale basis that supports this indication is poorly understood. Thus, we investigated the effect of an aerobic exercise on the parasitism, inflammation and oxidative tissue damage in a murine model of Trypanosoma cruzi-induced skeletal myositis. Wistar rats were randomized into four groups: trained not infected (TNI) and infected (TI), sedentary not infected (SNI) and infected (SI)...
