OBJECTIVE Seizures are the most common presenting symptom of newly diagnosed WHO Grade II gliomas (low-grade glioma [LGG]) and significantly impair quality of life. Although gross-total resection of LGG is associated with better seizure control, it remains unclear whether an extent of resection (EOR) "threshold" exists for long-term seizure control. Specifically, what proportion of FLAIR-positive tissue in patients with newly diagnosed LGG must be removed to achieve Engel Class I seizure freedom? To clarify the EOR threshold for long-term seizure control, the authors analyzed data from a consecutive series of patients with newly diagnosed LGG who presented with seizures and subsequently underwent microsurgical resection...

BACKGROUND: Myocardial dysfunction occurs in a variety of fetal disorders. Findings from adult cardiology, where n-terminal pro-B-type natriuretic peptide (nt-proBNP) is an established biomarker of left ventricular dysfunction have been extended to fetal life. Since fetal blood sampling is technically challenging we investigated amniotic fluid nt-proBNP for its suitability to diagnose fetal myocardial dysfunction. METHODS: Ultrasound, Doppler examination and echocardiography was applied to classify cases and controls...

BACKGROUND/OBJECTIVES: U.S. adults and children are equally likely to have allergic contact dermatitis. Historically the narrow geographic location of data-reporting providers has quantitatively and qualitatively limited the pediatric contact dermatitis data. The Pediatric Contact Dermatitis Registry was used to evaluate self-identified pediatric patch test providers within the United States with regard to demographic characteristics, geographic location, and practice patterns. METHODS: A wide range of U...

We investigated the quantitative analysis of sonographic images to predict fetal lung maturity of the canine foetus in normal pregnancy. Twelve bitches were recruited in the present study. Serial ultrasonographic exams were performed at three pre-determined time periods corresponding to the pseudoglandular (40-48 days of pregnancy), canalicular (49-56 days of pregnancy) and saccular phase (57-63 days of pregnancy) of lung development. Mean grey level (MGL) and the standard deviation of the histogram (SDH) of fetal lung and liver sonographic images were measured with dedicated software...

BACKGROUND: Population-based data on the development of subsequent thoracic cancers following the initial diagnosis of lung cancer are scarce. We evaluated this clinical scenario in lung cancer patients registered within the Surveillance, Epidemiology and End Results (SEER) database. METHODS: The SEER database (1988-2013) was queried using the SEER*Stat program to determine the clinico-pathological features of lung cancer patients who develop subsequent thoracic cancers as well as the characteristics of these subsequent cancers...

Currently available Interferon-γ release assay (IGRA) cannot reliably differentiate active TB (ATB) from non-active TB (non-ATB). A study was performed to evaluate the value of Mycobacterium tuberculosis (MTB) specific Th1 cell immune responses which test IFN-γ and IL-2 simultaneous for differentiating ATB from non-ATB. Forty-nine newly diagnosed inpatients with ATB (26 pulmonary TB and 23 extrapulmonary TB) were enrolled as the ATB group. Forty-five volunteers with latent tuberculosis infection (LTBI) and twenty with evidence of previous TB were enrolled during the same period as the non-ATB group...

BACKGROUND: Acute appendicitis is one of the most common causes of acute abdominal pain prompting emergency department (ED) visits. It is critical for the physicians to promptly and accurately diagnose acute appendicitis. The present study aimed to evaluate the diagnostic efficacy of Doppler ultrasonography (USG) in patients with acute appendicitis and compare this new method with other commonly used radio-diagnostic tools. METHODS: All patients who were diagnosed with acute appendicitis at the Kecioren Training and Research Hospital ED and later underwent appendectomy between October 2012 and April 2013 were included in the study...

INTRODUCTION: HIV self-testing (HIVST) is a discreet and convenient way to reach people with HIV who do not know their status, including many who may not otherwise test. To inform World Health Organization (WHO) guidance, we assessed the effect of HIVST on uptake and frequency of testing, as well as identification of HIV-positive persons, linkage to care, social harm, and risk behaviour. METHODS: We systematically searched for studies comparing HIVST to standard HIV testing until 1 June 2016...

BACKGROUND: Current guidelines recommend use of the aldosterone-renin ratio (ARR) for the case detection of primary aldosteronism followed by confirmatory tests to exclude false-positive results from further diagnostic workup. We investigated the hypothesis that this could be unnecessary in patients with a high ARR value if the quantitative information carried by the ARR is taken into due consideration. METHODS AND RESULTS: We interrogated 2 large data sets of prospectively collected patients studied with the same predefined protocol, which included the captopril challenge test...

OBJECTIVE: Malaysia has a high and rising prevalence of type 2 diabetes (T2D). While environmental (non-genetic) risk factors for the disease are well established, the role of genetic variations and gene-environment interactions remain understudied in this population. This study aimed to estimate the relative contributions of environmental and genetic risk factors to T2D in Malaysia and also to assess evidence for gene-environment interactions that may explain additional risk variation...

Hong Li, Johnny Siu-Hang Li
Researchers using the Lee-Carter approach have often assumed that the time-varying index evolves linearly and that the parameters describing the age pattern of mortality decline are time-invariant. However, as several empirical studies suggest, the two assumptions do not seem to hold when the calibration window begins too early. This problem gives rise to the question of identifying the longest calibration window for which the two assumptions hold true. To address this question, we contribute a likelihood ratio-based sequential test to jointly test whether the two assumptions are satisfied...

BACKGROUND: Whether post-anticoagulation D-dimer levels are useful in predicting recurrence in elderly patients with unprovoked venous thromboembolism is unknown. METHODS: We followed-up 157 patients aged ≥65 years with acute symptomatic unprovoked venous thromboembolism in a prospective multicenter cohort study. All patients completed 3-12 months of anticoagulation and then underwent quantitative D-dimer testing (ELISA, VIDAS DD) 12 months after the index venous thromboembolism...

BACKGROUND: Cervicogenic dizziness (CGD) is hard to diagnose as there is no objective test. OBJECTIVE: Can a brief assessment tool be derived from the Dizziness Handicap Inventory (DHI) to assist in screening for CGD? DESIGN: Case-control study with split-sample analysis. METHOD: 86 people with CGD and 86 people with general dizziness completed the DHI as part of the assessment of their dizziness. Descriptive statistics were used to assess how frequently each question on the DHI was answered 'yes' or 'sometimes' by participants with CGD and by participants with general dizziness...

Resistance to temozolomide (TMZ) chemotherapy poses a significant challenge in the treatment of glioblastoma (GBM). Hypermethylation in O(6)-methylguanine-DNA methyltransferase (MGMT) promoter is thought to play a critical role in this resistance. Pyrosequencing (PSQ) has been shown to be accurate and robust for MGMT promoter methylation testing. The unresolved issue is the determination of a cut-off value for dichotomization of quantitative MGMT PSQ results into "MGMT methylated" and "MGMT unmethylated" patient subgroups as a basis for further treatment decisions...

BACKGROUND: Bystander cardiopulmonary resuscitation (CPR) is associated with increased survival from cardiac arrest, yet bystander CPR rates are low in many communities. The overall prevalence of CPR training in the United States and associated individual-level disparities are unknown. We sought to measure the national prevalence of CPR training and hypothesized that older age and lower socioeconomic status would be independently associated with a lower likelihood of CPR training. METHODS AND RESULTS: We administered a cross-sectional telephone survey to a nationally representative adult sample...

Racial disparity in mental health service utilization (MHSU) persists, and youths are not an exception to the underutilization of services. Very limited research has been conducted on the determinants of MHSU among Black youth. Using a national sample of American Black youth, the current study investigated the association between demographic factors, socioeconomic status, psychiatric disorders, and self-rated health (SRH) on MHSU. We also tested the heterogeneity of the effects of SRH and psychiatric disorders based on ethnicity, gender, and their intersection...
