#1
REVIEW
Gabriel Paykin, Gerard O'Reilly, Helen Ackland, Biswadev Mitra
The National Emergency X-Radiography Utilization Study (NEXUS) criteria were derived from a heterogeneous group of adult blunt trauma patients, with the outcome measure assessed most commonly using plain X-ray radiographs. Recent observations have suggested inadequacy of these criteria for excluding injury in population subgroups such as the elderly. The aim of this systematic review was to determine the sensitivity of the NEXUS criteria in excluding cervical spine injury among older patients aged ≥65 years...

OBJECTIVE: To develop a modified Thrombolysis in Myocardial Infarction (TIMI) score to effectively risk stratify patients presenting to the ED with chest pain. METHODS: A prospective observational study was conducted at two metropolitan EDs. Data were obtained during patient interview. The primary outcome was major adverse cardiovascular events (MACE) within 30 days of presentation. Two separate modifications of the TIMI score were developed. These scores were compared to the original TIMI in terms of the area under the receiver operating characteristic curve and diagnostic accuracy statistics (sensitivity, specificity, positive and negative predictive values)...

Background Treatment of neovascular age-related macular degeneration (nvAMD) under real life conditions may differ from controlled prospective trials with respect to the number of injections and long term preservation of visual acuity. In many instances, intervals for controls and re-injection cannot be maintained as frequently as required. This case series examines actual intervals for control and re-injection visits, in order to estimate how prolonged intervals have an impact on momentary visual acuity and how long term visual outcome is affected...

Robert G H Wilke, Robert Patrick Finger, Helmut G Sachs
Background The evaluation of relationships in clinical case series is complicated by statistical pitfalls, one of which is spurious correlation. In this case, one or more potential factors are actually not related to a target measure, yet it may be wrongly inferred that they are. This may be due to either coincidence or the presence of a one or more confounding unregarded factors. In randomised clinical trials, it is attempted to eliminate such confounding factors or to control them by randomisation. However, this approach is not applicable in retrospective case series, and other statistical methods must be applied, such as multivariate analyses, taking into account all known variables...

Elevated intraocular pressure (IOP) is accepted to be one important criterion for glaucoma and is usually measured by applanation or rebound tonometry. The individual uncertainty due to central cornea thickness (CCT) is thereby corrected, while the error induced by age-related elastic modulus (EM) change of the cornea is ignored. To investigate its influence on IOP measurement, we derive a model including also the elastic modulus. Our approach is based on known equations from experimental physics and several assumptions being justified in this paper...

BACKGROUND: In order to achieve elimination of trachoma, a country needs to demonstrate that the elimination prevalence thresholds have been achieved and then sustained for at least a two-year period. Ghana achieved the thresholds in 2008, and since 2011 has been implementing its trachoma surveillance strategy, which includes community and school screening for signs of follicular trachoma and trichiasis, in trachoma-endemic districts. In 2015-2016, the country conducted a district level population-based survey to validate elimination of trachoma as a public health problem...

Fatty liver is a major health problem worldwide. People with hereditary deficiency of hormone-sensitive lipase (HSL) are reported to develop fatty liver. In this study, systemic and tissue-specific HSL-deficient mice were used as models to explore the underlying mechanism of this association. We found that systemic HSL deficient mice developed fatty liver in an age-dependent fashion between 3 and 8 months of age. To further explore the mechanism of fatty liver in HSL deficiency, liver-specific HSL knockout mice were created...

BACKGROUND: The presence of white matter hyperintensity (WMH) is related to poor long-term outcomes in stroke patients. However, the long-term outcome is unknown in patients with both large artery atherosclerosis (LAA) and WMH. METHODS: We investigated the impact of WMH on long-term outcome in patients with LAA. Consecutive patients in a prospective stroke registry were included. Patients were followed for a median of 7.7 years (interquartile range, 5.6-9.7). The degree of WMH was assessed by Fazekas grade on fluid-attenuated inversion recovery images...

BACKGROUND: Associations between repeated ocular infections with Chlamydia trachomatis in childhood and conjunctival scarring in adulthood are well established. Trachomatous scarring (TS) in children has also been observed in hyper-endemic areas, but data are scant regarding childhood scarring in areas where trachoma has been reduced to hypo-endemic levels. METHODS/PRINCIPLE FINDINGS: In this cross-sectional study, a random sample of children, ages 1-9 years, were selected from 38 communities in the formerly hyper-endemic district of Kongwa, Tanzania...

OBJECTIVE: Previous research has concluded that teachers are at a higher-than-normal risk for voice issues that can cause occupational limitations. While some risk factors have been identified, there are still many unknowns. PATIENTS AND METHODS: A survey was distributed electronically with 506 female teacher respondents. The survey included questions to quantify three aspects of vocal fatigue as captured by the Vocal Fatigue Index (VFI): (1) general tiredness of voice (performance), (2) physical discomfort associated with voicing (pain), and (3) improvement of symptoms with rest (recovery)...

The aim of this study was to evaluate the influence of initial noncavitated caries lesions on cavitated caries increment in preschool children. A 2-year cohort study was designed to include the participants of a survey on dental caries performed in 2010. Preschool children (12-59 months old) were examined for dental caries and classified as children with no caries lesions, with only initial lesions, with at least 1 moderate caries lesion, and with extensive lesions. Socioeconomic data were also collected. After 2 years, 466 children were re-examined (follow-up rate of 72...

Abdominal aortic aneurysm (AAA) is a silent, progressive disease with a high mortality and an increasing prevalence with aging. Smooth muscle cell (SMC) dysfunction contributes to gradual dilatation and eventual rupture of the aorta. Here we studied phenotypic characteristics in SMC cultured from end-stage human AAA (≥5 cm) and cells cultured from a porcine carotid artery (PCA) model of early and end-stage aneurysm. Human AAA-SMC presented a secretory phenotype and expressed elevated levels of the differentiation marker miR-145 (2...
