BACKGROUND: Venous thromboembolism (VTE) often complicates the clinical course of cancer. The risk is further increased by chemotherapy, but the trade-off between safety and efficacy of primary thromboprophylaxis in cancer patients treated with chemotherapy is uncertain. This is the second update of a review first published in February 2012. OBJECTIVES: To assess the efficacy and safety of primary thromboprophylaxis for VTE in ambulatory cancer patients receiving chemotherapy compared with placebo or no thromboprophylaxis...

BACKGROUND: Psychotic disorders are associated with high rates of sustained unemployment, however, little is known about the long-term employment outcome of people at ultra-high risk (UHR) of developing psychosis. We sought to investigate the long-term unemployment rate and baseline predictors of employment status at follow-up in a large UHR cohort. METHOD: 268 UHR patients recruited from the Personal Assessment and Crisis Evaluation clinic in Melbourne, Australia were followed-up over 2-14years after initial presentation to the service...

BACKGROUND: Social stressors are associated with an increased risk of psychosis. Stress sensitisation is thought to be an underlying mechanism and may be reflected in an altered autonomic stress response. Using an experimental Virtual Reality design, the autonomic stress response to social stressors was examined in participants with different liability to psychosis. METHOD: Fifty-five patients with recent onset psychotic disorder, 20 patients at ultra-high risk for psychosis, 42 siblings of patients with psychosis and 53 controls were exposed to social stressors (crowdedness, ethnic minority status and hostility) in a Virtual Reality environment...

INTRODUCTION: PMMA-augmentation of pedicle screws strengthens the bone-screw-interface reducing cut-out risk. Injection of fluid cement bears a higher risk of extravasation, with difficulty of application because of inconsistent viscosity and limited injection time. OBJECTIVE: To test a new method of cement augmentation of pedicle screws using radiofrequency-activated PMMA, which is suspected to be easier to apply and have less extravasations. METHODS: Twenty-seven fresh-frozen human cadaver lumbar spines were divided into 18 osteoporotic (BMD ≤ 0...

While a subset of patients with DLBCL relapsing after upfront chemoimmunotherapy can be cured with salvage therapy and autologous hematopoietic cell transplantation (auto-HCT), the outcome of patients with primary treatment failure (PTF) is less clear. For this study we analyzed 331 patients from 15 US institutions with DLBCL and PTF, defined as primary progression while on upfront chemoimmunotherapy (PP), residual disease at the end of upfront therapy (RD) or relapse < 6 months from end of therapy (early relapse; ER)...

PURPOSE: Osteolysis in total hip arthroplasty (THA) depends on polyethylene wear and dictates the survival of the prosthesis. Dual mobility in THAs, which is claimed to reduce dislocation risk, has very good long-term clinical results. However, little is known about how the liner wears in this design, compared to the standard single mobility model. METHODS: A comparative study looking at wear of a conventional ultra-high-molecular-weight polyethylene liner, using gravimetric measurement, between dual mobility implants and standard implants, was performed on a simulator in accordance with a normed protocol based on the same dimensions, environmental conditions and stresses...

Childhood adversity is associated with a range of mental disorders, functional impairment and higher health care costs in adulthood. In this study we evaluated if childhood adversity was predictive of adverse clinical and functional outcomes and health care costs in a sample of patients at ultra-high risk (UHR) for developing a psychosis. Structural Equation Modeling was used to examine the effect of childhood adversity on depression, anxiety, transition to psychosis and overall functioning at 4-year follow-up...

Tramadol is a unique analgesic medication, available in variety of formulations, with both monoaminergic reuptake inhibitory and opioid receptor agonist activity increasingly prescribed worldwide as an alternative for high-affinity opioid medication in the treatment of acute and chronic pain. It is a prodrug that is metabolized by cytochrome P450 (CYP) enzymes CYP2D6 and CYP3A4 to its more potent opioid analgesic metabolites, particularly the O-demethylation product M1. The opioid analgesic potency of a given dose of tramadol is influenced by an individual's CYP genetics, with poor metabolizers experiencing little conversion to the active M1 opioid metabolite and individuals with a high metabolic profile, or ultra-metabolizers, experiencing the greatest opioid analgesic effects...

AIM: Although the 16-item version of the Prodromal Questionnaire (PQ-16) is used as a screener in the early detection of psychosis risk, little is known about PQ-16 scores among adolescents referred to the Child and Adolescent Mental Health Services. We assessed such scores in adolescents referred to these services in the Netherlands, and also their associations with age, gender, diagnosis and level of functioning. METHODS: The PQ-16 was added to regular intake procedures...

5-Fluorouracil is commonly used for gastrointestinal cancer treatment in an adjuvant setting; however, the toxicity can lead to a reduction, delay, or discontinuation of treatment. We retrospectively investigated the association between the 5-fluorouracil degradation rate (5-FUDR) and genetic polymorphisms of TSER, DPYD, and MHTFR with toxicity in colorectal cancer patients treated with adjuvant FOLFOX. Pretreatment 5-FUDR and MTHFR A1298T or C677T, TSER, and DPYD gene polymorphisms were characterized in stages II-III colorectal cancer patients...

INTRODUCTION: Subjects with 22q11.2 deletion syndrome (22q11DS) and subjects with ultra-high risk for psychosis (UHR) share a risk of approximately 30% to develop a psychotic disorder. Studying these groups helps identify biological markers of pathophysiological processes involved in the development of psychosis. Total cortical surface area (cSA), total cortical grey matter volume (cGMV), cortical thickness (CT), and local gyrification index (LGI) of the cortical structure have a distinct neurodevelopmental origin making them important target markers to study in relation to the development of psychosis...

Bipolar I disorder is associated with deficits in the long-chain omega-3 fatty acid docosahexaenoic acid (DHA, 22:6n-3). The final biosynthesis of DHA is mediated by peroxisomes, and some heritable peroxisomal disorders are associated with DHA deficits and progressive psychopathology. The present cross-sectional study investigated whether medication-free asymptomatic and symptomatic youth with familial risk for bipolar I disorder exhibit impaired peroxisomal function using a comprehensive diagnostic blood panel...

Prenatal infection and subsequent abnormal neurodevelopment of offspring is involved in the etiology of schizophrenia. Brain-derived neurotrophic factor (BDNF) and its high affinity receptor, tropomyosin receptor kinase B (TrkB) signaling plays a key role in the neurodevelopment. Pregnant mice exposed to polyriboinosinic-polyribocytidylic acid [poly(I:C)] causes schizophrenia-like behavioral abnormalities in their offspring at adulthood. Here we found that the juvenile offspring of poly(I:C)-treated mice showed cognitive deficits, as well as reduced BDNF-TrkB signaling in the prefrontal cortex (PFC)...

BACKGROUND: Cannabis use shows a robust dose-dependent relationship with psychosis risk among the general population. Despite this, it has been difficult to link cannabis use with risk for transitioning to a psychotic disorder among individuals at ultra-high risk (UHR) for psychosis. The present study examined UHR transition risk as a function of cannabis use characteristics which vary substantially between individuals including age of first use, cannabis abuse severity and a history of cannabis-induced attenuated psychotic symptoms (APS)...

Patients with high-risk neuroblastoma remain a therapeutic challenge with significant numbers of patients failing to respond sufficiently to initial therapy. These patients with poor response to induction are considered as ultra high-risk and are in need of novel treatment strategies. Isotretinoin is part of the standard of care treatment for patients with high-risk disease who undergo high-dose chemotherapy with autologous stem cell rescue although some have questioned the optimal administration schedule. Prolonged use of isotretinoin was well tolerated and may have contributed to long-term survival in a group of patients with ultra high-risk neuroblastoma...

Multiple myeloma (MM) has been diagnosed based on the International Myeloma Working Group (IMWG) diagnostic criteria since 2003. In 2014, the IMWG updated these diagnostic criteria to add three specific biomarkers, i.e., 1) Clonal bone marrow plasma cell percentage ≥60%; 2) Involved: uninvolved serum free light chain ratio ≥100; 3) >1 focal lesion on MRI studies, based on CRAB features (hypercalcemia, renal failure, anemia, and bone lesions). An early diagnosis of MM can be made, allowing timely anti-MM treatment, in patients with the ultra-high-risk smoldering form of this disease...
