Objectives: To measure the utility of patients with ureteral stones under various medical regimes and to identify significant factors affecting utility for various health states. Methods: A cross-sectional survey was conducted to measure the utility of 89 patients on each health state related to the clinical management of ureteral stones. Health states with respect to intervention and treatment...

Recent studies show that regression-based tests of the asymmetric timeliness of earnings may be invalid. We develop an econometric model showing that these tests correctly identify whether or not earnings are conservative; however, the inclusion of future rents in equity values causes the regression coefficients to mismeasure the degree of conservatism. This mismeasurement biases cross-sectiona...

BACKGROUND Integrated Management of Childhood Illness (IMCI) is an effective 11-day standard training; however, due to budgetary expenses and human resource constraints, many health professionals cannot take 11 days off work. As a result, shortened training curriculums (6-day) have been proposed. We used a cross-sectional study to evaluate the effect of this shortened training on appropriate IM...

the present note arises from the author's talk at the conference ``ischia group theory 2014''. for subgroups $fle n$ of a group $g$ denote by $lat(f,n)$ the set of all subgroups of $n$, containing $f$. let $d$ be a subgroup of $g$. in this note we study the lattice $ll=lat(d,g)$ and the lattice $ll'$ of subgroups of $g$, normalized by $d$. we say that $ll$ satisfies sandwich classification theo...

Let E be an ample vector bundle of rank r on a projective variety X with only log-terminal singularities. We consider the nefness of adjoint divisors KX + (t − r) detE when t ≥ dimX and t > r. As a corollary, we classify pairs (X, E) with cr-sectional genus zero. Introduction. Let X be a smooth projective variety and KX the canonical bundle of X . For the study of X , it is useful to consider a...

UNLABELLED The objective of this study was to determine whether posttherapy (131)I SPECT/CT changed the need for additional cross-sectional imaging or modified the American Thyroid Association risk of recurrence classification. We performed planar imaging and SPECT/CT in a consecutive series of patients after (131)I therapy. METHODS Planar imaging and SPECT/CT were performed on 148 consecutiv...

Background There are limited data on levels of alcohol use in most sub-Saharan African countries. Objective We analyzed data from Uganda's non-communicable diseases risk factor survey conducted in 2014, to identify alcohol use prevalence and associated factors. Design The survey used the World Health Organization STEPS tool to collect data, including the history of alcohol use. Alcohol users we...

Public concern about childhood obesity and associated health problems calls for the identification of modifiable factors that could halt this epidemic. Parental perceptions of their children's weight status could be associated to how parents influence children's eating patterns. We aimed to identify the perceptions Puerto Rican parents have of their children's weight and children's own percepti...
