OBJECTIVES: To examine temporal national trends of operative approach for cystectomy and identify demographic or clinical predictive factors that influence choice of approach. METHODS: We performed a retrospective cohort study of patients who underwent cystectomy for bladder cancer between 2010 and 2013 using the National Cancer Database (NCDB). Approach was stratified by open vs. minimally invasive (robotic or laparoscopic). Univariate Pearson chi-square and multivariate logistic regression analysis was used to assess relationships between demographic and hospital factors and the receipt of minimally invasive or open surgical approach...

Pulmonary embolism (PE) is a frequent cause of death and serious disability with a risk extending far beyond the acute phase of the disease. Anticoagulant treatment reduces the risk for death and recurrent VTE after a first PE. The optimal duration of anticoagulation after a first episode of PE remains controversial and should be made on an individual basis, balancing the estimated risk for recurrence without anticoagulant treatment against bleeding risk under anticoagulation. Current recommendations on duration of anticoagulation are based on a 3% per year risk of major bleeding expected during long-term warfarin treatment...

Modern diagnostic strategies for pulmonary embolism diagnosis almost all rely on an initial assessment of the pretest probability. Clinical prediction rules are decision-making tools using combinations of easily available clinical predictors to define the probability of a disease. The assessment of the clinical probability of pulmonary embolism has an important impact on the diagnostic strategy and on therapeutic management. Clinical prediction rules provide accurate and reproducible estimates of clinical probability...

OBJECTIVES: The American Academy of Pediatrics provides little guidance on when to discontinue phototherapy in newborns treated for hyperbilirubinemia. We sought to develop a prediction rule to estimate the probability of rebound hyperbilirubinemia after inpatient phototherapy. METHODS: Subjects for this retrospective cohort study were infants born in 2012 to 2014 at ≥35 weeks' gestation at 16 Kaiser Permanente Northern California hospitals who received inpatient phototherapy before age 14 days...

Importance: Transthyretin cardiac amyloidosis (ATTR) is an underrecognized cause of heart failure (HF) in older individuals, owing in part to difficulty in diagnosis. ATTR can result from substitution of valine for isoleucine at codon 122 of the transthyretin (TTR) gene (V122I), present in 3.43% of African American individuals. Objective: To examine whether serum retinol-binding protein 4 (RBP4), an endogenous TTR ligand, could be used as a diagnostic test for ATTR V122I amyloidosis...

BACKGROUND: Cardiac allograft vasculopathy (CAV) remains an important cause of graft failure after heart transplantation (HT). Although many risk factors for CAV have been identified, there are no clinical prediction models that enable clinicians to determine each recipient's risk of CAV. METHODS: We studied a cohort of 14,328 heart transplant recipients whose data were reported to the International Society for Heart and Lung Transplantation Registry between 2000 and 2010...

Graphs and tables are indispensable aids to quantitative research. When developing a clinical prediction rule that is based on a cardiovascular risk score, there are many visual displays that can assist in developing the underlying statistical model, testing the assumptions made in this model, evaluating and presenting the resultant score. All too often, researchers in this field follow formulaic recipes without exploring the issues of model selection and data presentation in a meaningful and thoughtful way...

Predicting the likelihood of harm posed by mentally disordered offenders remains controversial. It is proposed that a Bayesian approach may help quantify the uncertainty surrounding such prediction. An example of this approach quantifying the risk of breast cancer in the event of a positive mammogram is provided. Copyright © 2017 John Wiley & Sons, Ltd.

: 39 Background: Tumour factors (eg primary site, size) helpful in prognostication in early stage cancer may be less important than patient factors, such as Karnofsky performance status (KPS), later in the disease trajectory. We evaluated the utilization of the parameters attitude (ATT) and psychosocial support (PSS) in predicting remaining lifespan by two experienced multidisciplinary teams (MDT). METHODS: After clinical assessment of consecutive patients, a quantitative clinical prediction of survival (CPS) was made prospectively, independently and anonymously by each health care provider (HCP)...

BACKGROUND: Acute lower respiratory tract infections (LRTI) are a frequent cause of hospitalization and mortality in South Africa; however, existing respiratory severity scores may underestimate mortality risk in HIV-infected adults in resource limited settings. A simple predictive clinical score for low-resource settings could aid healthcare providers in the management of patients hospitalized with LRTI. METHODS: We analyzed 1,356 LRTI hospitalizations in adults aged ≥18 years enrolled in Severe Acute Respiratory Illness (SARI) surveillance in three South African hospitals from January 2010 to December 2011...

BACKGROUND: There is substantial variability in the prognosis of acute low back pain (LBP). The ability to identify the probability of individual patients recovering by key time points would be valuable in making informed decisions about the amount and type of treatment to provide. Predicting recovery based on presentation 1-week after initially seeking care is clinically important and may be more accurate than predictions made at initial presentation. The aim of this study was to predict the probability of recovery at 1-week, 1-month and 3-months after 1-week review in patients who still have LBP 1-week after initially seeking care...

BACKGROUND & AIMS: Model for end-stage liver disease (MELD) score has been extensively used to prioritize patients for liver transplantation and determine their prognosis, but with limited predictive value. Autonomic dysfunction may correlate with increased mortality after liver transplant. In this study, two autonomic biomarkers, complexity and deceleration capacity, were added to the predicting model for one-year mortality after liver transplantation. METHODS: Thirty patients with end-stage liver diseases awaiting liver transplantation were included...

David Armstrong
Using an analysis of the British Medical Journal over the past 170 years, this article describes how changes in the idea of a population have informed new technologies of medical prediction. These approaches have largely replaced older ideas of clinical prognosis based on understanding the natural histories of the underlying pathologies. The 19(th)-century idea of a population, which provided a denominator for medical events such as births and deaths, was constrained in its predictive power by its method of enumerating individual bodies...

Osteosarcomas (OSs) represent a huge challenge to improve the overall survival, especially in metastatic patients. Increasing evidence indicates that both tumor-associated elements but also on host-associated elements are under a remarkable effect on the prognosis of cancer patients, especially systemic inflammatory response. By analyzing a series prognosis of factors, including age, gender, primary tumor size, tumor location, tumor grade, and histological classification, monocyte ratio, and NLR ratio, a clinical predictive model was established by using stepwise logistic regression involved circulating leukocyte to compute the estimated probabilities of metastases for OS patients...
