SHP2, a cytoplasmic protein-tyrosine phosphatase encoded by the PTPN11 gene, is involved in multiple cell signaling processes including Ras/MAPK and Hippo/YAP pathways. SHP2 has been shown to contribute to the progression of a number of cancer types including leukemia, gastric and breast cancer. It also regulates T-cell activation by interacting with inhibitory immune checkpoint receptors such as the programmed cell death 1 (PD-1) and B- and T-lymphocyte attenuator (BTLA). Thus, SHP2 inhibitors have drawn great attention by both inhibiting tumor cell proliferation and activating T cell immune responses toward cancer cells...

Adolescents with anorexia nervosa who have obsessive-compulsive (OC) features respond poorly to family-based treatment (FBT). This study evaluated the feasibility of combining FBT with either cognitive remediation therapy (CRT) or art therapy (AT) to improve treatment response in this at-risk group. Thirty adolescents with anorexia nervosa and OC features were randomized to 15 sessions of FBT + CRT or AT. Recruitment rate was 1 per month, and treatment attrition was 16.6% with no differences between groups...

INTRODUCTION: Femoral shaft fractures generally occur in young adults following a high-energy trauma and are prone to delayed union/non-union. Novel therapies to stimulate bone regeneration will have to mimic some of the aspects of the biology of fracture healing; however, which are these aspects is unclear. Locked intramedullary nailing is the current treatment of choice for the stabilisation of femur shaft fractures, and it is associated with accelerated healing and increased union rates...

BACKGROUND: Central venous access devices (CVADs) are essential for total parenteral nutrition administration in patients with short bowel syndrome (SBS). However, they are fraught with complications including infection and venous thromboembolism (VTE), which increases associated morbidity and mortality in this population. There is evidence linking the development of CVAD-associated thrombosis and line-related infection. Thus, it has been postulated that prevention of catheter-related clot formation could minimize the risk of infection originating from the catheter...

OBJECTIVES: Antenatal corticosteroids are standard of care for women at risk of a preterm birth and demonstrated to be protective against poor outcomes in neonates including respiratory disorders, mortality and intraventricular hemorrhage (IVH). Its benefits may vary by gestational age, and accurate estimation is needed in a single-center population to account for practice variation. METHODS: A retrospective cohort of infants admitted to the hospital's neonatal intensive care unit, 1997-2015...

BACKGROUND: Recent studies have shown dismal outcomes when chronic lymphocytic leukemia progresses to Richter syndrome after patients receive ibrutinib, with a median overall survival ranging from 2.6 to 3.5 months. Published data on efficacy of allogeneic hematopoietic cell transplantation in Richter syndrome are limited to single-center case series and registry data. PATIENTS AND METHODS: We evaluated the efficacy of allogeneic transplantation in 10 patients, median age of 63 (range, 50-74) years, allografted at a median of 5 (range, 4-25) months from diagnosis of Richter syndrome...

Locked nucleic acid containing antisense oligonucleotides (LNA-ASOs) have the potential to modulate the disease-related gene expression by the RNaseH-dependent degradation of mRNAs. Pulmonary drug delivery has been widely used for the treatment of lung disease. Thus, the inhalation of LNA-ASOs is expected to be an efficient therapy that can be applied to several types of lung disease. Because the lung has a distinct immune system against pathogens, the immune-stimulatory effect of LNA-ASOs should be considered for the development of novel inhaled LNA-ASOs therapies...

Individuals with HIV infection are at elevated risk of developing end-stage renal disease. However, their outcomes after starting chronic dialysis in the contemporary era of widespread antiretroviral therapy are not well described. Using detailed data from a national dialysis provider, we determined HIV status by administrative codes and antiretroviral medication prescriptions, with hepatitis C virus (HCV) co-infection status provided by routinely measured serology. The survival on dialysis among 5348 individuals in the HIV(+) group and 1863 HIV(+)/HCV(+) individuals to a HIV(-)/HCV(-) reference cohort was compared...

BACKGROUND & AIMS: In patients with gastroesophageal reflux disease (GERD) and excessive belching, most belches are supragastric, and can induce reflux episodes and worsen GERD. Supragastric belching (SGB) might be reduced with diaphragmatic breathing exercises. We investigated whether diaphragmatic breathing therapy is effective in reducing belching and proton pump inhibitor (PPI) refractory gastroesophageal reflux symptoms. METHODS: We performed a prospective study of 36 consecutive patients with GERD refractory to PPI therapy and a belching visual analogue scale (VAS) score of 6 or more, seen at a gastroenterology clinic at a tertiary hospital in Singapore from April 2015 through October 2016...

The fabrication of well-behaved drug delivery systems that can transport drugs to specifically treat cancer cells rather than normal cells is still a tremendous challenge. A novel drug delivery system with two types of tumor-related mRNAs as "keys" to open the multiple valves of the nanocarrier to control drug release was developed. Hollow mesoporous silica nanoparticles were employed as the nanocarrier and dual DNAs targeting two intracellular mRNAs were employed as "multi-locks" to lock up the nanocarrier...

Despite combination antiretroviral therapy (cART), acquired immunodeficiency syndrome (AIDS), predominantly caused by the human immunodeficiency virus type 1 (HIV-1), remains incurable. The barrier to a cure lies in the virus' ability to establish a latent infection in HIV/AIDS patients. Unsurprisingly, efforts for a sterilizing cure have focused on the "shock and kill" strategy using latency-reversing agents (LRAs) to complement cART in order to eliminate these latent reservoirs. However, this method faces numerous challenges...

AIM: Resources devoted to health care are limited, therefore setting priorities is required. It differs between countries whether decision-making concerning health care technologies focus on broad economic perspectives or whether focus is narrow on single budgets ("silo mentality"). The cost perspective as one part of the full health economic analysis is important for decision-making. With the case of oral anticoagulants in patients with nonvalvular atrial fibrillation (NVAF), the aim is to discuss the implication of the use of different cost perspectives for decision-making and priority setting...

Direct-acting antivirals have revolutionized the treatment of hepatitis C virus (HCV) infection in patients with chronic kidney disease, with implications for the timing of antiviral treatment among kidney transplant candidates and for the use of HCV viremic donors. A recent consensus conference reviewed the available data on the safety and cost-effectiveness of expanding access to HCV-positive organs to HCV-negative recipients. Early trials are promising, but larger trials and a plan for obtaining HCV therapy in the posttransplantation period are needed...

The incidence rate of chronic lymphocytic leukemia (CLL) in the United States is approximately 0.005%; men are at slightly higher risk than women. Bony involvement or pathological fracture rarely occurs in CLL, and it may be the initial presentation. An 85-year-old woman presented with acute respiratory failure secondary to pneumonia. Symptomatology included dyspnea. She was found to have pathological fracture of the femur caused by CLL. The diagnosis of CLL had been made 6 years previously, but the patient had refused therapy...

HIV-1 Tat activates viral transcription and limited Tat transactivation correlates with latency establishment. We postulated a "block-and-lock" functional cure approach based on properties of the Tat inhibitor didehydro-Cortistatin A (dCA). HIV-1 transcriptional inhibitors could block ongoing viremia during antiretroviral therapy (ART), locking the HIV promoter in persistent latency. We investigated this hypothesis in human CD4(+) T cells isolated from aviremic individuals. Combining dCA with ART accelerates HIV-1 suppression and prevents viral rebound after treatment interruption, even during strong cellular activation...

Extreme prematurity is the leading cause of death among children under 5 years of age. Currently, there is no treatment for bronchopulmonary dysplasia (BPD), the most common complication of extreme prematurity. Experimental studies in animal models of BPD suggest that mesenchymal stromal cells (MSCs) are lung protective. To date, no systematic review and meta-analysis has evaluated the preclinical evidence of this promising therapy. Our protocol was registered with Collaborative Approach to Meta-Analysis and Review of Animal Data from Experimental Studies prior to searching MEDLINE (1946 to June 1, 2015), Embase (1947 to 2015 Week 22), Pubmed, Web of Science, and conference proceedings (1990 to present) for controlled comparative studies of neonatal animal models that received MSCs or cell free MSC-derived conditioned media (MSC-CM)...
