As antimicrobial stewardship increasingly receives worldwide attention for improving patient care by optimizing antimicrobial therapy, programs are evaluating new tools that may augment antimicrobial stewardship activities. Biomarkers are objective, accurate, and reproducible measures that provide information about medical conditions. A systematic literature search using PubMed/MEDLINE databases was performed to evaluate the use of novel biomarkers as additions to the antimicrobial stewardship armamentarium...

OBJECTIVE: Immune dysfunction is an important component of the disease process underlying Systemic Sclerosis (SSc), but the mechanisms contributing to altered immune cell function in SSc remain poorly defined. Here, we measured the expression and function of the co-inhibitory receptors (co-IRs) PD-1, TIGIT, TIM-3, and LAG-3 in lymphocyte subsets from the peripheral blood of SSc patients. METHODS: Co-IR expression levels on immune cell subsets were analyzed using a 16-color flow cytometry panel...

Muscle fatigue affecting glenohumeral and/or scapular muscles is suggested as one of the contributing factors to the development of subacromial impingement syndrome (SAIS). Nonetheless, the fatigability of shoulder girdle muscles in association with the pathomechanics of SAIS has not been reported. This study aimed to measure and compare fatigue progression within the shoulder girdle musculature of patients and healthy controls. 75 participants including 39 patients (20 females; 19 males) and 36 healthy controls (15 females; 21 males) participated in the study...

Synaptic dysfunction is the best anatomical correlate of early cognitive impairment in Alzheimer's disease (AD). Electroencephalography (EEG) directly reflects brain electrical activity at the level of synapses. The aim of the present study was to investigate correlations of quantitative EEG measures, global field power (GFP) and global field synchronization (GFS), with conventional cerebrospinal fluid (CSF) biomarkers of neurodegeneration in patients diagnosed with subjective cognitive decline (n = 210), mild cognitive impairment (n = 230), and AD (n = 197)...

OBJECTIVES: Insufficient gynecological follow-up and cervical screening has been reported in women with cystic fibrosis (CF). Some of these patients will require a pulmonary transplantation, known to be associated with a higher risk of cervical dysplasia. The aim of this study was to explore the results of cervical screening in adult women with CF, and to report the prevalence of abnormal pap smear tests in this population. STUDY DESIGN: We retrospectively analyzed medical records of sexually active women with CF who attended a gynecological consultation in Lyon University CF referral center between June 2014 and December 2015...

CARs are synthetic receptors that reprogram immune cells for therapeutic purposes. They comprise three canonical domains for antigen recognition, T cell activation, and costimulation. The CAR cDNA is genetically integrated in the T cell genome. Autologous CAR T cells are generated from the patient's peripheral blood T cells and expand in the recipient to eliminate the targeted tumor. To view this Bench to Bedside, open or download the PDF.

Purpose Breast cancer, the most common cancer worldwide, is the leading cause of cancer mortality in Ghanaian women. Previous studies find Ghanaian women are diagnosed at a younger age and at more advanced stages (III and IV), and have tumors with characteristics similar to African American women. We sought to remedy gaps in knowledge about breast cancer survival in Ghana and its relation to demographic and biologic factors of the tumors at diagnosis to assist in cancer control and registration planning. Methods Individuals with a breast cancer diagnosis who sought care at Komfo Anokye Teaching Hospital from 2009 to 2014 were identified via medical records...

Non-alcoholic fatty liver disease (NAFLD) is the most common form of liver disease and ranges from isolated steatosis to NASH. To determine whether circulating fatty acids could serve as diagnostic markers of NAFLD severity and whether specific fatty acids could contribute to the pathogenesis of NASH, we analyzed two independent NAFLD patient cohorts and used the methionine- and choline-deficient diet (MCD) NASH mouse model. We identified six fatty acids that could serve as non-invasive markers of NASH in patients with NAFLD...

SEVERE MALARIA: Even with the best available treatment, the mortality from severe Plasmodium falciparum malaria remains high. Typical features at death are high parasite loads and obstructed micro- vasculature. Infected erythrocytes (IE) containing mature parasites bind to the host receptor heparan sulfate, which is also an important receptor for merozoite invasion. To block merozoite invasion has not previously been proposed as an adjunctive therapeutic approach but it may preclude the early expansion of an infection that else leads to exacerbated sequestration and death...

INTRODUCTION: It is estimated that major neurocognitive disorders will affect 115.4 million people by 2050, representing a significant financial burden for society. Likewise, functional dependence for basic or instrumental activities of daily life is usually a consequence of the greater prevalence of disabling pathologies, and of the progressive decrease of the physiological reserve due to aging. OBJECTIVES: To determine the ratio between the functional test and prediction of deterioration of cognitive function in geriatric patients...

Glioblastoma, one of the most aggressive primary brain tumors, is characterized by highly immunosuppressive microenvironment. This contributes to glioblastoma resistance to standard treatment modalities and allows tumor growth and recurrence. Several immune-targeted approaches have been recently developed and are currently under preclinical and clinical investigation. Oncolytic viruses, including the autonomous protoparvovirus H-1 (H-1PV), show great promise as novel immunotherapeutic tools. In a first phase I/IIa clinical trial (ParvOryx01), H-1PV was safe and well tolerated when locally or systemically administered to recurrent glioblastoma patients...

Elotuzumab is the first monoclonal antibody approved for the treatment of relapsed-refractory multiple myeloma (MM) in combination with lenalidomide, an immunodulatory drug, and dexamethasone. We report on a multiply pre-treated MM patient with disease progression due to appearance of new focal lesions on imaging modalities, who was started on a combination treatment of elotuzumab, lenalidomide, and dexamethasone. After completion of three cycles of the new therapy the patient responded very well with a major decline of serological myeloma activity parameters serum monoclonal protein, kappa light chains, free light chains (FLC) ratio...

CASE: Surgical management of tibial plateau fractures can be challenging, and complications can be devastating. We report the case of a lateral tibial plateau fracture malunion with an associated intra-articular depression, which we treated with an open-book osteotomy, obviating the need for an early corrective osteotomy or knee arthroplasty. CONCLUSION: A tibial plateau fracture malunion can be reconstructed. The surgical team should give priority to salvage options, which can obviate or delay the need for and the implications of an early total knee arthroplasty, especially in a young and active patient...

CASE: A 41-year-old woman presented 5 years after glenohumeral arthrodesis. She experienced symptomatic relief following conversion to reverse total shoulder arthroplasty, regaining nearly full passive range of motion and >50% of normal active forward flexion, abduction, internal rotation, and external rotation. CONCLUSION: Conversion from glenohumeral arthrodesis to reverse total shoulder arthroplasty in a patient with a functioning deltoid and adequate bone stock may provide symptomatic relief and improved function in the setting of symptomatic glenohumeral arthrodesis refractory to conservative measures...

CASE: A 16-year-old girl with Pompe disease underwent surgery for scoliosis. She had been able to walk without any assistance, and kept her balance by swinging her waist. Therefore, we performed posterior selective spinal correction and fusion to avoid any adverse effects on walking ability that could occur with immobilization of the lumbosacral spine. After surgery, she was highly satisfied with her ability to perform the activities of daily living. CONCLUSION: For nonambulatory patients with scoliosis and Pompe disease, long fusion from the upper thoracic spine to the pelvis is generally required...

CASE: A 23-year-old active-duty military service member sustained an unusual irreducible fracture-dislocation of the ankle joint. Preoperative computed tomography showed an anterolateral tibial (Chaput) fragment entrapped within the distal syndesmosis, preventing adequate reduction. An open reduction of the fragment was performed in the operating room, which allowed near-anatomic reduction and internal fixation of the tibiotalar joint. At the 21-month follow-up visit, the patient remained on active duty in the Navy without limitations...
