Nair, Kesavan Sreekantan,Raj, Sherin,Tiwari, Vijay Kumar,Piang, Lam Khan Asian Pacific Journal of Cancer Prevention 2013 Asian Pacific journal of cancer prevention Vol.14 No.9
Background: To assess the treatment pattern and expenditure incurred by cancer patients undergoing treatment at government tertiary hospitals in India. Materials and Methods: A cross-sectional study of 508 cancer patients randomly selected from tertiary cancer hospitals funded by central/state governments located in major cities of five states in India, namely Kerala, Maharashtra, Rajasthan, West Bengal and Mizoram, during March - May 2011 was conducted. Information related to direct costs, indirect costs and opportunity costs incurred on investigations and treatment, major source of payment and difficulties faced by patients during the course of treatment was collected. Results: About 45% of the patients used private health facilities as the first point of contact for cancer related diseases as against 32% in public hospitals. About 47% sought private health facilities for cancer investigations, 21% at district/sub-district hospitals, and about 4% contacted primary health care facilities. A majority of the patients (76%) faced financial problems while undergoing treatment. Conclusions: The results highlight the importance of involving the primary health care system in the cancer prevention activities.

One of the major challenges in wireless body area networks (WBANs) is sensor fault detection. This paper reports a method for the precise identification of faulty sensors, which should help users identify true medical conditions and reduce the rate of false alarms, thereby improving the quality of services offered by WBANs. The proposed sensor fault detection (SFD) algorithm is based on Pearson correlation coefficients and simple statistical methods. The proposed method identifies strongly correlated parameters using Pearson correlation coefficients, and the proposed SFD algorithm detects faulty sensors. We validated the proposed SFD algorithm using two datasets from the Multiparameter Intelligent Monitoring in Intensive Care database and compared the results to those of existing methods. The time complexity of the proposed algorithm was also compared to that of existing methods. The proposed algorithm achieved high detection rates and low false alarm rates with accuracies of 97.23% and 93.99% for Dataset 1 and Dataset 2, respectively.

WO3-incorporated C-TiO2 nanotubes were successfully fabricated using radio frequency sputtering technique. The e®ects of sputtering powers on the nanotube morphology, crystal structure, optical properties and visible photoresponse were investigated. Lattice substitution of WO3species within the lattice of C?TiO2 nanotubes has an important function in maximizing the photocurrent generation. WO3-incorporated C?TiO2 nanotubes exhibit good visible photoresponse compared with C?TiO2 nanotubes. The interpretation of interband states has an important function in improving photoinduced electron transport.

The present study conducted with 100 oral cancer patients at a private tertiary care hospital in Delhidemonstrated that stage III cancer was associated with longer use of tobacco and poor oral hygiene. There was also statistically significant association (p<.05) between consumption of tobacco and alcohol. More than 60% treatment expenditure was on surgery followed by accommodation (9%) and investigations (8%). The effect of tobacco was well known among patients as 76% of the patients knew that common cancer in tobacco chewer is 'oral cancer', 22% of the patients however responded that they did not know which cancer is common in tobacco chewers. 58% said that they learnt about ill effects of tobacco from media while 24% said they learnt from family and friends. Out of 78 tobacco users, 60 (77%) said that they never received help to quit tobacco while 18(23%) have received help to quit.
