Purpose To investigate the value of a new cervical sonographic sign, called the jellyfish sign (JS), for predicting the risk of maternal morbidity in cases of abnormally invasive placenta (AIP) previa totalis. Materials and Methods Retrospective evaluation of transvaginal (TV) and transabdominal (TA) scans performed in all singleton pregnancies with placenta previa totalis. JS, i. e. the absence of the normal linear demarcation between the placenta previa and the cervix, was evaluated by TV scans. The presence/severity of AIP and outcomes of maternal morbidity were related to this sign...

BACKGROUND: The association between folic acid (FA) supplementation and mortality in continuous ambulatory peritoneal dialysis (CAPD) patients is unclear. METHODS: FA exposure was calculated as a percentage of cumulative duration of drug usage to total follow-up duration (FA%). A total of 1,358 patients were classified by a cutoff value of FA%. The association of FA with mortality was evaluated using Cox proportional hazards models. RESULTS: The cutoff value of FA% for predicting mortality was <34% at a median follow-up of 40...

BACKGROUND AND PURPOSE: Little is known about the short- and long-term outcomes of ischemic stroke of undetermined mechanism (ISUM). METHODS: Subjects were recruited from the Mashhad Stroke Incidence Study. Ischemic stroke (IS) was classified on the basis of the TOAST criteria. We further categorized patients with ISUM into ISUMneg (negative clinical/test results for large artery, small artery) and ISUMinc (incomplete investigations). Cox proportional hazard models and the competing-risk regression model were used to compare 1 and 5 years mortality (all-causes) and recurrent rate among IS subtypes...

BACKGROUND: Current approaches to assess violence risk in secure hospitals are resource intensive, limited by accuracy and authorship bias and may have reached a performance ceiling. This study seeks to develop scalable predictive models for violent offending following discharge from secure psychiatric hospitals. METHODS: We identified all patients discharged from secure hospitals in Sweden between January 1, 1992 and December 31, 2013. Using multiple Cox regression, pre-specified criminal, sociodemographic, and clinical risk factors were included in a model that was tested for discrimination and calibration in the prediction of violent crime at 12 and 24 months post-discharge...

Maternal depression has been suggested to be an independent risk factor for both dysregulated hypothalamic-pituitary-adrenal axis (HPA) functioning and shorter telomere length in offspring. In contrast, research suggests that individual differences in mindfulness may act as a protective factor against one's own telomere degradation. Currently, research has yet to investigate the association between longitudinal changes in maternal mental health (depressive symptoms and mindfulness) and salivary infant telomere length, and whether such changes might be mediated by alterations in infant cortisol response...

The chemical pollutants, including pesticides and other industrial chemicals, have resulted in significant risks to the whole ecosystem. Therefore, the ecological risk assessment of chemicals is vital and necessary. Since honey bee (Apis mellifera) is probably among the most exposed species to the polluting chemicals, we focused on the in silico estimation of honey bee toxicity (HBT) of chemical and the analysis of the relevance of chemical HBT and several key physical-chemical properties and structural characteristics...

Background: The prognostic score of the International Germ Cell Cancer Collaborative Group (IGCCCG) in metastatic germ-cell cancers (mGCC) relies on treatments delivered before 1990. It is unclear, if this score is still relevant to contemporary cohorts of patients who receive modern-type chemotherapy and supportive care. Patients and Methods: All patients who underwent cisplatin/etoposide based first-line chemotherapy for mGCC at the University Hospital Zurich (USZ) between 1991 and 2016 were identified retrospectively...

Background: Oral health is important for maintaining general health among the elderly. However, a longitudinal association between poor oral health and general health has not been reported. We investigated whether poor oral status can predict physical weakening (physical frailty, sarcopenia, subsequent disability) and identified the longitudinal impact of the accumulated poor oral health (i.e., oral frailty) on adverse health outcomes, including mortality. Methods: A total of 2,011 elderly individuals (aged ≥65 years) participated in the baseline survey of the Kashiwa study in 2012...

Compared with neural biomarkers of risk for mental illness, little is known about biomarkers of resilience. We explore if greater executive control-related prefrontal activity may function as a resilience biomarker by "rescuing" risk associated with higher threat-related amygdala and lower reward-related ventral striatum activity. Functional MRI was used to assay baseline threat-related amygdala, reward-related ventral striatum, and executive control-related prefrontal activity in 120 young adult volunteers...

BACKGROUND: Aberrant promoter DNA methylation of the cysteine dioxygenase 1 (CDO1) gene is found in various human cancers and is associated with clinical outcome. In this study, we assessed for the first time the clinicopathological significance of CDO1 methylation in primary gallbladder cancer (GBC) in comparison with non-malignant gallbladder disease. METHODS: CDO1 DNA methylation was quantified using quantitative TaqMan methylation specific PCR (Q-MSP) in 99 primary GBC patients together with the 78 corresponding non-tumor tissues and 26 benign gallbladder disease (including 7 patients with xanthogranulomatous cholecystitis) who underwent surgical resection between 1986 and 2014...

BACKGROUND: Although significant progress has been made in reducing malaria transmission globally in recent years, a large number of people remain at risk and hence the gains made are fragile. Funding lags well behind amounts needed to protect all those at risk and ongoing contributions from major donors, such as the President's Malaria Initiative (PMI), are vital to maintain progress and pursue further reductions in burden. We use a mathematical modelling approach to estimate the impact of PMI investments to date in reducing malaria burden and to explore the potential negative impact on malaria burden should a proposed 44% reduction in PMI funding occur...

BACKGROUND: Adults experiencing homelessness and serious mental illnesses (SMI) are at an increased risk for poor mental health and treatment outcomes compared to stably housed adults with SMI. The additional problem of alcohol misuse further complicates the difficulties of those living with homelessness and SMI. In this secondary data analysis, we investigated the impact of homelessness on attrition and alcohol use in a contingency management (CM) intervention that rewarded alcohol abstinence in outpatients with SMI...

Here, we aimed to identify an immunohistochemical (IHC)-based classifier as a prognostic factor in patients with esophageal squamous cell carcinoma (ESCC). A cohort of 235 patients with ESCC undergoing radical esophagectomy (with complete clinical and pathological information) were enrolled in the study. Using the least absolute shrinkage and selection operator (LASSO) regression model, we extracted six IHC features associated with progression-free survival (PFS) and then built a classifier in the discovery cohort (n=141)...

INTRODUCTION: Patients with acute pulmonary embolism(APE)who present with right ventricular dysfunction (RVD) have a worse prognosis. This study aimed to evaluate the value of routine biochemical parameters in predicting RVD and 30-day mortality in patients with APE. METHODS: We retrospectively collected the clinical data for 154 enrolled patients, including the neutrophil-to-lymphocyte ratio (NLR), platelet-to-lymphocyte ratio (PLR), D-dimer, cardiac troponin I (cTnI), and N-terminal pro-brain natriuretic peptide (NT-proBNP)...

J Chipman, D Braun
The integrated discrimination improvement (IDI) is commonly used to compare two risk prediction models; it summarizes the extent a new model increases risk in events and decreases risk in non-events. The IDI averages risks across events and non-events and is therefore susceptible to Simpson's paradox. In some settings, adding a predictive covariate to a well calibrated model results in an overall negative (positive) IDI. However, if stratified by that same covariate, the strata-specific IDIs are positive (negative)...
