BACKGROUND AND AIMS: Large-scale studies regarding the long-term outcomes of adalimumab (ADA) treatment in Asian patients with Crohn's disease (CD) are still scarce. METHODS: We retrospectively analyzed the long-term outcomes of ADA treatment in Korean CD patients who commenced on scheduled ADA treatment at Asan Medical Center between November 2008 and July 2016. Clinical response was defined as maintaining ADA treatment without dose intensification (DI) and/or major abdominal surgery (MAS)...

Mitochondrial activity and metabolic reprogramming influence the phenotype of cancer cells and resistance to targeted therapy. We previously established that an Insulin-like Growth Factor 1 (IGF-1)-inducible mitochondrial UTP carrier (PNC1/SLC25A33) promotes cell growth. This prompted us to investigate whether IGF signaling is essential for mitochondrial maintenance in cancer cells, and whether this contributes to therapy resistance. Here, we show that IGF-1 stimulates mitochondrial biogenesis in a range of cell lines...

Eupolauridine and liriodenine are plant-derived aporphinoid alkaloids that exhibit potent inhibitory activity against the opportunistic fungal pathogens Candida albicans and Cryptococcus neoformans However, the molecular mechanism of this antifungal activity is unknown. In this study, we show that eupolauridine 9591 (E9591), a synthetic analog of eupolauridine, and liriodenine methiodide (LMT), a methiodide salt of liriodenine, mediate their antifungal activities by disrupting mitochondrial iron-sulfur (Fe-S) cluster synthesis...

BACKGROUND: Previous studies have provided substantial evidence on the association of Aggregatibacter actinomycetemcomitans (Aa), and its highly leukotoxic JP2 genotype, with localized aggressive periodontitis (LAP). The present study aims to evaluate the presence of JP2 in LAP individuals following periodontal treatment. METHODS: Sixty African American LAP patients between ages 5 and 25 years were examined. At baseline, pocket depth (PD), clinical attachment level (CAL), bleeding on probing (BoP) and plaque index were measured and subgingival plaque was collected from both LAP diseased sites and healthy sites for each participant...

Ovarian cancer is one of the most important causes of cancer-related death among women in the world. Despite advances in ovarian cancer treatment, 70-80% of women who initially respond to therapy eventually relapse and die. There is evidence that a small population of cells within the tumors called cancer stem cells (CSCs) could be responsible for treatment failure due to their enhanced chemoresistance and tumorigenicity. These cells reside in a niche that maintains the principal properties of CSCs. These properties are associated with the capacity of CSCs to interact with different cells of the tumor microenvironment including mesenchymal stem cells, endothelial cells, immune cells, and fibroblasts, promoting cancer progression...

BACKGROUND AND OBJECTIVES: Post-transplant lymphoproliferative disorders arising after kidney transplantation portend an increased risk of morbidity and mortality. Retransplantation of patients who had developed post-transplant lymphoproliferative disorder remains questionable owing to the potential risks of recurrence when immunosuppression is reintroduced. Here, we investigated the feasibility of kidney retransplantation after the development of post-transplant lymphoproliferative disorder...

BACKGROUND: Nephroblastoma and neuroblastoma belong to the most common abdominal malignancies in childhood. Similarities in the initial presentation may provide difficulties in distinguishing between these two entities, especially if unusual variations to prevalent patterns of disease manifestation occur. Because of the risk of tumor rupture, European protocols do not require biopsy for diagnosis, which leads to misdiagnosis in some cases. CASE PRESENTATION: We report on a 4½-year-old girl with a renal tumor displaying radiological and laboratory characteristics supporting the diagnosis of nephroblastoma...

BACKGROUND: In adults, infliximab (IFX) levels correlate with disease activity, and antibodies to IFX (ATIs) predict treatment failure. We aimed to determine the association of IFX levels and ATIs with disease activity in a paediatric population. We prospectively collected blood, stool, and clinical data from 65 patients (age 10.5-15.1 years) with Crohn's disease (CD) before IFX administration, and measured IFX trough levels, ATIs, and faecal calprotectin levels (CPT). Samples were collected during maintenance therapy...

Importance: Nivolumab plus ipilimumab (nivo + ipi) is a standard treatment of advanced melanoma. Two randomized trials describe high objective response rates by Response Evaluation Criteria in Solid Tumors. The trials assessed toxic effects using the Common Terminology Criteria for Adverse Events (CTCAE), which may underestimate incidence of clinically significant immune-related adverse events (AEs). Objective: To describe detailed toxic effects and time to treatment failure of patients with melanoma treated with nivo + ipi in a prospective cohort...

Children with cerebral palsy experience spasticity that can be debilitating and cause significant pain and contractures. Intrathecal baclofen (ITB) therapy can help relieve this spasticity and improve the quality of life for these patients, but it comes with risk. Withdrawal from the medication in case of abrupt discontinuation of delivery can be life-threatening. Regular maintenance of the system is mandatory. Having a program in place to manage the device and support patients helps to ensure their safety...

PURPOSE/BACKGROUND: Clozapine is associated with hematological abnormalities, with neutropenia and agranulocytosis of most concern. Granulocyte colony-stimulating factor (G-CSF) has been used to support clozapine rechallenge after neutropenia with the aim of maintaining the neutrophil count. This study aims to explore the practice, use, safety, and efficacy of G-CSF in this context. METHODS/PROCEDURES: We conducted a systematic review to identify all studies investigating or describing G-CSF as a prophylaxis to enable continued clozapine treatment during a rechallenge...

Anti-tumor necrosis factor (TNF) therapy has revolutionized the treatment of inflammatory bowel disease (IBD). However, up to 30% of patients with IBD show no clinical benefit and are defined as having a primary nonresponse. Primary nonresponse to a biologic can be attributed to either pharmacokinetic or pharmacodynamic issues, such as those involved in secondary loss of response. Pharmacokinetic issues are linked to undetectable or subtherapeutic drug concentrations because of either an accelerated non-immune-mediated clearance or immunogenicity and the development of antidrug antibodies, whereas pharmacodynamic issues are likely related to "non-TNF driven" disease...

PURPOSE: The JLGK0901 study showed the noninferiority of stereotactic radiosurgery (SRS) alone as initial treatment of 5 to 10 brain metastases (BMs) compared with 2 to 4 BMs in terms of overall survival and most secondary endpoints (Lancet Oncol 2014;15:387-95). However, observation periods were not long enough to allow confirmation of the long-term safety of SRS alone in patients with 5 to 10 BMs. METHODS AND MATERIALS: This was a prospective observational study of Gamma Knife SRS-treated patients with 1 to 10 newly diagnosed BMs enrolled at 23 facilities between March 1, 2009, and February 15, 2012...

OBJECTIVE: To compare the real-world, 5-year clinical and cost impact of maintaining treatment with the tumor necrosis factor-α inhibitors (anti-TNFs) adalimumab, etanercept, or infliximab vs dose tapering or withdrawal in rheumatoid arthritis (RA) patients who have achieved remission (defined as a 28-joint count Disease Activity Score [DAS28] < 2.6) or low disease activity (LDA; DAS28 < 3.2). METHODS: Using a 5-year Markov model with 1-month cycle length, we examined the clinical and cost impact of three treatment strategies: withdrawal, tapering, or maintenance of anti-TNFs among RA patients in remission or who have achieved LDA...

BACKGROUND: Fluid and electrolyte therapy is an important component in the care of the hospitalized child. Previous pediatric guidelines have followed the Holliday-Segar method of calculating and delivering maintenance IV fluids, using hypotonic fluids in maintenance therapy. However, research demonstrates that hypotonic fluids can lead to iatrogenic hyponatremia and that isotonic fluid is a safer alternative. OBJECTIVE: To provide the ideal approach to intravenous (IV) fluid use in the hospitalized child and determine the safety and effectiveness of isotonic maintenance fluid therapy...

Cognitive content and processes are central to theories of post-traumatic stress disorder (PTSD). In this paper, we highlight recent findings on cognitive factors in PTSD. Evidence for the role of negative post-traumatic cognitions in PTSD has continued to mount, with cognitions mediating PTSD symptoms and predicting PTSD over and above other key variables. Researchers have also continued to implicate cognitive processes like rumination in the development and maintenance of PTSD. Finally, we review how cognitive-behavioral therapies interrupt dysfunctional cognitive processes in PTSD and highlight research supporting the theory that changes in cognitions are the mechanism of these treatments...
