BACKGROUND Native vertebral osteomyelitis (NVO) is a common form of hematogenous osteomyelitis, with Staphylococcus aureus (S. aureus) being the most commonly isolated organism. Dalbavancin is approved by the US Food and Drug Administration (FDA) for the treatment of acute bacterial skin and skin structure infections (ABSSSI) and has a sufficiently promising pharmacokinetic and pharmacodynamic profile to be considered for the treatment of vertebral osteomyelitis. We describe here what is probably the first reported case of using multiple weekly dalbavancin to treat a complicated methicillin-resistant Staphylococcus aureus (MRSA) bacteremia and vertebral osteomyelitis...

Group 2 innate lymphoid cells (ILC2s) are effector cells within the mucosa and key participants in type 2 immune responses in the context of allergic inflammation and infection. ILC2s develop in the bone marrow from common lymphoid progenitor cells, but little is known about how ILC2s egress from the bone marrow for hematogenous trafficking. In this study, we identified a critical role for IL-33, a hallmark peripheral ILC2-activating cytokine, in promoting the egress of ILC2 lineage cells from the bone marrow...

PURPOSE: To evaluate the correlation of visual and keratometry outcomes after corneal cross-linking (CXL) in patients with keratoconus with cone epithelium-specific gene expression levels. METHODS: Corneal epithelium was obtained from 35 eyes that underwent accelerated CXL (KXLII, 9 mW/cm for 10 min). Using corneal topography, epithelium over the cone and periphery was obtained separately from each subject. The ratio of gene expression for lysyl oxidase (LOX), matrix metalloproteinase 9 (MMP9), bone morphogenic protein 7, tissue inhibitor of metalloproteinase 1, collagen, type I, alpha 1, and collagen, type IV, alpha 1 (COL IVA1) from the cone and peripheral cornea was correlated with the outcome of cross-linking surgery...

Lynne Gledstone-Brown, Douglas McHugh
Peripheral intravenous cannula (PIVC) placement is often an essential emergency medicine precursor to lifesaving treatment, but it is not harmless. Patients frequently and without proper consideration of the consequences receive a 'just-in-case' PIVCs as part of their assessment and admission, which, in a not insignificant number of patients, remains unused or idle in situ. We reviewed the literature and performed a thematic analysis of data collated from 21 articles published in the past 24 years regarding redundant PIVCs...

Gliomas are primary malignancies of the brain. Tumors are staged based on malignancy, nuclear atypia, and infiltration of the surrounding brain parenchyma. Tumors are often diagnosed once patients become symptomatic, at which time the lesion is sizable. Glioblastoma (grade IV glioma) is highly aggressive and difficult to treat. Most tumors are diagnosed de novo. The gold standard of therapy, implemented over a decade ago, consists of fractionated radiotherapy and temozolomide, but unfortunately, chemotherapeutic resistance arises...

Triggers of the autoimmune response that leads to type 1 diabetes (T1D) remain poorly understood. A possibility is that parallel changes in both T cells and target cells provoke autoimmune attack. We previously documented greater Ca2+ transients in fibroblasts from T1D subjects than non-T1D after exposure to fatty acids (FA) and tumor necrosis factor α (TNFα). These data indicate that metabolic and signal transduction defects present in T1D can be elicited ex vivo in isolated cells. Changes that precede T1D, including inflammation, may activate atypical responses in people that are genetically predisposed to T1D...

BACKGROUND: Patients with cervical or high-thoracic spinal cord injury (SCI) often present reduced gastric emptying and early satiety. Ghrelin provokes motility via gastric vagal neurocircuitry and ghrelin receptor agonists offer a therapeutic option for gastroparesis. We have previously shown that experimental high-thoracic injury (T3-SCI) diminishes sensitivity to another gastrointestinal peptide, cholecystokinin. This study tests the hypothesis that T3-SCI impairs the vagally mediated response to ghrelin...

Poor graft function (PGF) is a severe complication of haematopoietic stem cell transplantation (HSCT) and administration of donor stem cell boosts (SCBs) represents a therapeutic option. We report 50 paediatric patients with PGF who received 61 boosts with CD34+ selected peripheral blood stem cells (PBSC) after transplantation from matched unrelated (n = 25) or mismatched related (n = 25) donors. Within 8 weeks, a significant increase in median neutrophil counts (0·6 vs. 1·516 × 109 /l, P < 0·05) and a decrease in red blood cell and platelet transfusion requirement (median frequencies 1 and 7 vs...

BACKGROUND/AIM: There is no doubt that colorectal cancer (CRC) poses a major threat to public health worldwide, and despite improvement in managements, prognosis still remains an irritating question with no definite answer. Being a fundamental player in cancer metabolism, glucose transporter 1 (GLUT1) could be utilized as a prognostic biomarker that could fuel development of new treatment strategies. The aim of this study was to assess the validity of GLUT1 expression as a prognostic biomarker and to elucidate to what extent it is immersed in poor clinical outcome among CRC patients...

Introduction: Tumours connected with head and neck comprise about 5% of all tumours. The most frequent histological type of laryngeal carcinoma is squamous cell carcinoma. Different research projects suggest that the role of T lymphocytes might be significant in tumour development. iNKT cells are a new subpopulation of T cells and show cytotoxic activity against tumours. iNKT cells participate in modulating the function of other cells which have anti-tumour properties and secrete cytokines, which have pro-inflammatory and anti-inflammatory effects...

Intentional insulin overdose may lead to severe and refractory hypoglycemia. Exogenous dextrose administration is the mainstay of therapy for these patients and is effective in most cases. However, in patients with a functional pancreas, exogenous dextrose administration may precipitate endogenous insulin release leading to rebound hypoglycemia. We describe a case report of a 41-year-old woman who injected 300 units of insulin aspart with suicidal intent. Her initial blood glucose was 2.3 mmol/L (41 mg/dL)...

BACKGROUND: Nivolumab is an anti-PD1 checkpoint inhibitor active in patients with advanced melanoma and as adjuvant therapy in high-risk metastatic melanoma patients. METHODS: In this single-center retrospective analysis, we investigated the CD73 enzyme activity in patients with metastatic melanoma stage IV and its correlation with the response to nivolumab. The soluble CD73 (sCD73) enzyme activity was measured in the serum of 37 melanoma patients before receiving nivolumab and the Harrel's C index was used to find the best cut-off for this biomarker...

Intravenous sedation is effective to reduce fear and anxiety in dental treatment. It also has been used for behavior modification technique in dental patients with special needs. Midazolam and propofol are commonly used for intravenous sedation. Although there have been many researches on the effects of midazolam and propofol on vital function and the recovery profile, little is known about muscle power. This review discusses the effects of intravenous sedation using midazolam and propofol on both grip strength and bite force...

REVIEW
Audrey Boulamery, Sophie Desplat-Jégo
Observed in many central nervous system diseases, neuroinflammation (NI) proceeds from peripheral immune cell infiltration into the parenchyma, from cytokine secretion and from oxidative stress. Astrocytes and microglia also get activated and proliferate. NI manifestations and consequences depend on its context and on the acute or chronic aspect of the disease. The tumor necrosis factor-like weak inducer of apoptosis (TWEAK)/Fn14 pathway has been involved in chronic human inflammatory pathologies such as neurodegenerative, autoimmune, or malignant diseases...
