Cyanobacterial toxins, particularly microcystins (MCs) and cylindrospermopsin (CYN), are responsible for toxic effects in humans and wildlife. In order to counteract or prevent their toxicity, various strategies have been followed, such as the potential application of chemoprotectants. A review of the main substances evaluated for this aim, as well as the doses and their influence on cyanotoxin-induced toxicity, has been performed. A search of the literature shows that research on MCs is much more abundant than research on CYN...

Background: Finding the most appropriate regression model for survival data in cancer casesin order to determine prognosis is an important issue in medical research. Here we compare Cox and parametric regression models regarding survival of children with acute leukemia in southern Iran. Methods: In a retrospective cohort study, information for 197 children with acute leukemia over 6 years was collected through observation and interviews. In order to identify factors affecting their survival, the Cox and parametric (exponential, Weibull, log-logistic, log-normal, Gompertz and generalized gamma) models were fitted to the data...

BACKGROUND: Study design labels are used to identify relevant literature to address specific clinical and research questions and to aid in evaluating the evidentiary value of research. Evidence from the human healthcare literature indicates that the label "case series" may be used inconsistently and inappropriately. OBJECTIVE: Our primary objective was to determine the proportion of studies in the canine and feline veterinary literature labeled as case series that actually corresponded to descriptive cohort studies, population-based cohort studies, or other study designs...

Kadia Petricca, Asfaw Bekele
A critical element in building stronger health systems involves strengthening good governance to build capacity for transparent and fair health planning and priority setting. Over the past 20 years, the ethical framework Accountability for Reasonableness (A4R) has been a prominent conceptual guide in strengthening fair and legitimate processes of health decision-making. While many of the principles embedded within the framework are congruent with Western conceptualizations of what constitutes procedural fairness, there is a paucity in the literature that captures the degree of resonance between these principles and the views of decision makers from non-Western settings; particularly in Africa, where many countries have only recently, within the last 20-30 years, become more democratic...

BACKGROUND: The recovery process of a psychiatric patient is related to his primary informal caregiver's style of coping with stress. There is insufficient literature on validations of instruments that measure coping styles in this population. OBJECTIVE: To adapt and validate a scale to measure coping strategies in primary informal caregivers. METHOD: The adapted scale was based on the Extreme Coping Scale of López-Vázquez and Marván. Items from that scale were adapted for application to informal caregivers...

Hepcidin is the main regulator of iron homeostasis and dysregulation of proteins involved in iron metabolism has been associated with tumorogenesis. However, to date, no epidemiological study has researched the association between hepcidin levels and gastric cancer risk. To further investigate the relationship between hepcidin levels and gastric cancer risk, we conducted a nested case-control study (EURGAST) within the multicentric European Prospective Investigation into Cancer and Nutrition (EPIC) study. The study included 456 primary incident gastric adenocarcinoma cases and 900 matched controls that occurred during an average of 11 years of follow-up...

REVIEW
Robin Queen
Ankle osteoarthritis is a debilitating disease with approximately 50,000 new cases per year leading to skeletal deformity, severe and recurrent pain, cartilage breakdown, and gait dysfunction limiting patient mobility and well-being. Although many treatments (total ankle arthroplasty (TAA), ankle fusion (arthrodesis), and ankle distraction arthroplasty) relieve pain, it is not clear that these procedures significantly improve patient mobility. The goal of the research presented here is to summarize what is presently known about lower extremity gait mechanics and outcomes and to quantify the impact of ankle osteoarthritis and TAA have on these measures using an explicitly holistic and mechanistic approach...

BACKGROUND: Greater than 40% of renal cell carcinoma (RCC) cases in the United States are attributed to excessive body weight. Moreover, obesity also may be linked to RCC prognosis. However, the molecular mechanisms underlying these associations are unclear. In the current study, the authors evaluated the role of promoter methylation in obesity-related genes in RCC tumorigenesis and disease recurrence. METHODS: Paired tumors (TU) and normal adjacent (N-Adj) tissues from 240 newly diagnosed and previously untreated white patients with RCC were examined...

In recent years, the poorly remarkable goals achieved in terms of patients' important outcomes for ovarian cancer have fueled our interest towards the study of its metabolic roots. Within this research pipeline, we assessed the association between the expression of the glucose transporter GLUT1, as expressed at the tumor tissue level, and circulating pre-surgical levels of fasting glucose in a case series including data from 40 patients with high FIGO stage serous ovarian cancer. Patients who provided data to the current analysis were randomly selected from a larger cohort...

REVIEW
H J Scholten, A Pourtaherian, N Mihajlovic, H H M Korsten, R A Bouwman
Ultrasound guidance is becoming standard practice for needle-based interventions in anaesthetic practice, such as vascular access and peripheral nerve blocks. However, difficulties in aligning the needle and the transducer can lead to incorrect identification of the needle tip, possibly damaging structures not visible on the ultrasound screen. Additional techniques specifically developed to aid alignment of needle and probe or identification of the needle tip are now available. In this scoping review, advantages and limitations of the following categories of those solutions are presented: needle guides; alterations to needle or needle tip; three- and four-dimensional ultrasound; magnetism, electromagnetic or GPS systems; optical tracking; augmented (virtual) reality; robotic assistance; and automated (computerised) needle detection...

BACKGROUND: Disease activity can be determined using clinical, endoscopic or histologic criteria in patients with ulcerative colitis (UC). Persistent disease activity is associated with poor outcomes. Histologic disease activity has been shown to be associated with relapse, colectomy and colorectal cancer. The ability to objectively evaluate microscopic disease activity using histology is important for both clinical practice and clinical trials. However, the operating properties of the currently available histologic indices remain unclear...

INTRODUCTION: Despite the seriousness of the event, maternal deaths are substantially underreported. There is often a missed opportunity to learn from such tragedies. The aim of the study was to identify maternal deaths in the five Nordic countries, to classify causes of death based on internationally acknowledged criteria, and to identify areas that would benefit from further teaching, training or research to possibly reduce the number of maternal deaths. MATERIAL AND METHODS: We present data for the years 2005-2013...

Buddhist-derived meditation practices are currently being employed as a popular form of health promotion. While meditation programs draw inspiration from Buddhist textual sources for the benefits of meditation, these sources also acknowledge a wide range of other effects beyond health-related outcomes. The Varieties of Contemplative Experience study investigates meditation-related experiences that are typically underreported, particularly experiences that are described as challenging, difficult, distressing, functionally impairing, and/or requiring additional support...

In this paper, we propose to detect the running applications in a server by classifying the observed power consumption series for the purpose of data center energy consumption monitoring and analysis. Time series classification problem has been extensively studied with various distance measurements developed; also recently the deep learning-based sequence models have been proved to be promising. In this paper, we propose a novel distance measurement and build a time series classification algorithm hybridizing nearest neighbor and long short term memory (LSTM) neural network...
