Evaluation or perfusion and thermal parameters of skiin tissue using cold provocation and thermographic measurements

Measurement of the perfusion coefficient and thermal parameters of skin tissue using dynamic thermography is presented in this paper. A novel approach based on cold provocation and thermal modelling of skin tissue is presented. The measurement was performed on a person’s forearm using a special cooling device equipped with the Peltier module. The proposed method first cools the skin, and then measures the changes of its temperature matching the measurement results with a heat transfer model to estimate the skin perfusion and other thermal parameters. In order to assess correctness of the proposed approach, the uncertainty analysis was performed

United States Health Policies and Late-stage Breast and Colorectal Cancer Diagnosis: Why Such Disparities by Age?

Background: Colorectal and breast cancers are the second most common causes of cancer deaths in the US. Population cancer screening rates are suboptimal and many cancers are diagnosed at an advanced stage, which results in increased morbidity and mortality. Younger populations are more likely to be diagnosed at a later stage, and this age disparity is not well understood. We examine the associations between late-stage breast cancer (BC) and colorectal cancer (CRC) diagnoses and multilevel factors, focusing on individual state regulations of insurance and health practitioners, and interactions between such policies and age. We expect state-level regulations are significant predictors of the rates of late-stage diagnosis among younger adults. Methods: We included adults of all ages, with BC or CRC diagnosed between 2004 –2009, obtained from a newly available cancer population database covering 98 % of all known new cancer cases. We included personal characteristics, linked with a set of county and state-level predictors based on residence. We applied multilevel models to robustly examine differences in risk of late-stage cancer diagnosis across age groups (defined as age 65+ or \u3c 65), focusing specifically on the effects of state regulatory factors and their interactions with age. Results: Late stage BC diagnoses range from 24 %-36 %, while CRC diagnoses range from 54 %-60 % of newly diagnosed BC or CRC cases across states. After controlling statistically for many confounding factors at three levels, age \u3c 65 is the largest person-level predictor for CRC, while black race is the largest predictor for BC. State regulations of health markets exhibit significant interactions with age groups. Conclusions: The state regulatory climate is an important predictor of late-stage BC and CRC diagnoses, especially among people younger than Medicare eligible age (65). State regulations can enhance the climate of access for younger, less well-insured or uninsured persons who fall outside normative screening guidelines

How generalizable are the SEER registries to the cancer populations of the USA?

We determined whether the current SEER registries are representative of the nation’s cancer cases or the socio-demographic characteristics

Using residential segregation to predict colorectal cancer stage at diagnosis: two different approaches

Studies have found a variety of evidence regarding the association between residential segregation measures and health outcomes in the US. Some have focused on any individuals living in residentially segregated places, while others have examined whether persons of specific races or ethnicities living in places with high segregation of their own race or ethnicity have differential outcomes. This paper compares and contrasts these two approaches in the study of predictors of late-stage CRC diagnoses in a cross-national study. We argue that it is very important when interpreting results from studies like this to carefully consider the geographic scope of the analysis, which can significantly change the context and meaning of the results

Persepsi Siswa Terhadap Pelaksanaan Upacara Bendera Dalam Pembentukan Sikap Nasionalisme

The objectives of this research were to describe and explain the perception of students on the implementation of a flag ceremony in forming of the attitude of nationalism. The method used in this study was descriptive quantitative research. The population in this research were 125 people and 31 people as the sample. Data collecting technique was using interview and analyzing the data was using percentage. The results of the study showed that the indicator of understanding as many as 6,45 percent students in negative criteria or do not understand, 58,06 percent students in tended to be positive criteria. In indicator of responses as many as 22,58 percent were disagree with the flag ceremony, 45,16 percent were agree with the flag ceremony. In indicator of hope as many as 22,58 percent were disagree with the flag ceremony formed the nationalism, 41,93 percent were agree with the flag ceremony formed the nationalism.Tujuan penelitian ini untuk mendeskripsikan dan menjelaskan tentang Persepsi Siswa Terhadap Pelaksanaan Upacara Bendera Dalam Pembentukan Sikap Nasionalisme Siswa, penelitian ini menggunakan metode deskriptif kuantitatif.
