Objective: In this research, the patterns of cancer incidence and mortality in areas with different gross domestic product per capita (GDPPC) levels in China were explored, using data from population-based cancer registries in 2013, collected by the National Central Cancer Registry (NCCR). Methods: Data from 255 cancer registries were qualified and included in this analysis. Based on the GDPPC data of 2014, cities/counties were divided into 3 levels: high-, middle- and low-GDPPC areas, with 40,000 and 80,000 RMB per year as cut points...

Single-source dual-energy CT (ssDECT) allows the reconstruction of iodine density images (IDIs) from projection based computing. We hypothesized that adding adaptive statistical iterative reconstruction (ASiR) could improve image quality. The aim of our study was to evaluate the effect and determine the optimal blend percentages of ASiR for IDI of myocardial late iodine enhancement (LIE) in the evaluation of chronic myocardial infarction using ssDECT. A total of 28 patients underwent cardiac LIE using a ssDECT scanner...

PURPOSE: To compare the diagnostic performance of CT enterography (CTE) images obtained at 1 millisievert (mSv) and reconstructed with filtered back projection (FBP) and adaptive statistical iterative reconstruction (ASIR) with those of half-dose CTE images for the evaluation of active inflammation in patients with Crohn's disease. METHODS: Forty-six consecutive patients (mean age 29 years; range 15-59 years) with Crohn's disease underwent CTE which comprised a standard-dose scan at the enteric phase (45 s), a half-dose scan with ASIR at the portal venous phase (70 s), and 1 mSv scans with FBP and ASIR at the delayed phase (90 s) under a fixed 120 kVp and variable mAs...

OBJECTIVE: To evaluate the clinical application of a full model-based iterative reconstruction (MBIR) algorithm in the ultra-low-dose paranasal sinus CT imaging of children. MATERIALS AND METHODS: In the first phase, 16 low-dose CT dacryocystography (DCG) (80 kV/64 mAs) scans were reconstructed with MBIR and filtered back-projection (FBP) to demonstrate noise reduction capability of MBIR. MBIR images were also compared with the images of 21 standard-dose paranasal sinus patients reconstructed with adaptive statistical iterative reconstruction (ASIR) algorithm...

It is widely accepted that the estimation of biological attributes in the human skeleton is more accurate when population-specific standards are applied. With the shortage of such data for contemporary North African populations, it is duly required to establish population-specific standards. We present here the first craniometric standards for sex determination of a contemporary Tunisian population. The aim of this study was to analyze the correlation between sex and metric parameters of the skull in this population using CT scan analysis and to generate proper reliable standards for sex determination of a complete or fragmented skull...

The aim of this study was to determine the incidence trends of cutaneous melanoma (CM) and squamous cell carcinoma (SCC) in Cluj County, from 1998 to 2011, and the 5-year net survival between 2006 and 2010. Data on all cases of CM and SCC between 1998 and 2011 were obtained from Cluj Cancer Registry. Incidence rates were age standardized by the direct method Age Standardized Incidence Rate (ASIR), using the world standard population. Trends and annual percentage change (APC) of incidence rates were calculated by joinpoint regression analysis...

BACKGROUND: For First Nations (FN) peoples living in British Columbia (BC), little is known regarding cancer in the population. The aim of this study was to explore cancer incidence and survival in the FN population of BC and compare it to the non-FN population. METHODS: All new cancers diagnosed from 1993 to 2010 were linked to the First Nations Client File (FNCF). Age-standardized incidence rates (ASIR) and rate ratios, and 1- and 5-year cause-specific survival estimates and hazard ratios were calculated...

The research reported in this article is based on the hypothesis that crosslinking of starch can make it a potential wall material for targeted delivery of probiotics by altering its digestion. Three probiotic strains namely Lactobacillus casei, Lactobacillus brevis and Lactobacillus plantarum were microencapsulated with resistant starch. Encapsulation yield (%) of resistant starch microspheres was in the range of 43.01-48.46. The average diameter of resistant starch microparticles was in the range of 45.53-49...

Abnormal uterine bleeding is characterized by painful and/or excessive menorrhea, chronic pelvic pain due to the endometriosis (Em). Osteopathic treatment is commonly used in the gynecological dysfunctions. The aim of the present case study was to explore the effect of osteopathic treatment (OT) for a woman with abnormal uterine bleeding related pain and quality of life (QoL). We reported a case of 29 year old female who presented with chief complaints of increased flow during periods, lower abdominal pain, leukorrhoea, lower back pain and with occasional constipation for the last 3 years...

The increasing burden of lung cancer (LC) in Crete, Greece, has raised certain concerns about the potential association of environmental risk factors with LC. The aim of this study was to assess outdoor air pollution (OAP) and the risk for LC mortality for the first time in Crete using LC primary data. 5057 LC cases (diagnosed from 1992 to 2013) were obtained from the Cancer Registry of Crete (http://www.crc.uoc.gr) and followed up until 2014. The age-standardized incidence and mortality rates (ASIR) were calculated...
