Objective. To evaluate the feasibility of an online training module, Certified Smoking Cessation Service Provider (CSCSP), developed for practicing pharmacists to equip pharmacy students with knowledge necessary for smoking cessation counseling and to assess the changes in student knowledge and skills regarding smoking cessation following training.Design. Sixty third-year and 80 fourth-year pharmacy undergraduates (N=140) were given access to an online module, the main intervention in the study. Two linkable questionnaires were administered to assess students’ preintervention and postintervention knowledge. For the third-year students, an additional role-play training component was incorporated, and student skills were assessed during week 14 with an Objective Structured Clinical Examination (OSCE).Assessment. Preintervention and postintervention knowledge assessments were completed by 130 (92.8%) students. Sixty-six students scored above 50% for the knowledge component postintervention, compared to 13 at preintervention, demonstrating significant improvement (x2(1, N=130)=32, p=0.003). All third-year students completed the intervention, and 66.7% were able to counsel excellently for smoking cessation, scoring more than 80%.Conclusion. The CSCSP online module developed for practicing professionals was found suitable for equipping pharmacy undergraduates with knowledge on smoking cessation topics. The module, along with role-play training, also equipped students with knowledge and skills to provide smoking cessation counseling. 相似文献

ObjectiveTo identify the chikungunya outbreaks in both indoor and outdoor patients in some selected hospitals in our locality and the burden and magnitude of the disease, to compare different system of medicines (allopathic, Ayurvedic, homeopathy etc) and to explore the knowledge, attitude and practices of pharmacists and other health care professionals in the treatment of chikungunya.MethodsA six-month study was carried out. Detailed history was taken from the case history, personal interview of doctors and suspected cases. Personal data such as name age, sex, location, date of onset of illness, medical history, general/systemic examination features, drugs used (allopathy, Ayurveda, homeopathy, or traditional) for the treatment, etc. were noted down. A simple questionnaire was prepared and distributed to various doctors practicing various systems of medicines.ResultsA total of 209 suspected cases were identified from July to December, 2009. People in the age group of 20–40 years were more affected. The study revealed that females were more affected than males. The Grade-III (58.73%) population was more prone to chikungunya than Grade-II (38.75%) and Grade-I (2.87%). It showed that fever, pain in muscles, and sleeping disturbances were the intense symptoms of chikungunya. Myocarditis and arthritis were concomitant diseases which worsened chikungunya symptoms. It also indicated the effective medicine for compliance is nonsteroidal antiinflammatory drugs (NSAIDS).ConclusionsFrom our study we found that in some places there is no proper documentation, even though there are proper guidelines framed by the relevant authorities. It can be concluded from the study that all the systems of medicine are equally important for the management of chikungunya. Additional effort in promoting the guidelines at local level and proper documentation helps to achieve the goal of curbing the chikungunya. It is high time to increase our effort and promote these messages at grassroot level which benefits the society/community as a whole. 相似文献

RATIONALE AND OBJECTIVES: Stereographic display has been proposed as a possible method of improving performance in reading computed tomographic (CT) examinations acquired for lung cancer screening. Optimizing such displays is important given the large volume of image data that must be evaluated for each of these examinations. This study is designed to explore certain tradeoffs between rendering methods designed for the stereo display of CT images. MATERIALS AND METHODS: Stereo CT image compositing methods, including distance-weighted averaging, distance-weighted maximum intensity projection (MIP), and conventional MIP, were applied to lung CT images and compared for lung nodule detection and characterization. RESULTS: Using the Jonckheere test indicated a statistically significant (P < .01) increase in contrast among the three compositing methods. Wilcoxon-Mann-Whitney test showed significant differences in contrast between distance-weighted averaging and conventional MIP (P < .01) and between averaging and distance-weighted MIP (P < .05), but not between distance-weighted MIP and conventional MIP (P > .05). Conventional MIP compositing provided the highest image contrast, but produced ambiguities in local geometric detail and texture, whereas averaging resulted in the lowest contrast, but preserved geometric detail. Distance-weighted MIP partially recovered geometric information, which was lost in images composited by means of conventional MIP. CONCLUSION: Our results indicate that distance-weighted MIP may be a better choice for nodule detection in stereo lung CT images for its high local contrast and partial preservation of geometric information, whereas compositing by means of distance-weighted averaging is preferable for nodule characterization. The relative clinical value of these compositing methods needs to be evaluated further. 相似文献

Antral biopsy specimens were processed for Helicobacter pylori by Gram staining, rapid urease test (RUT) and culture from 25 patients with symptoms of duodenal ulcer, amongst whom the positivity rate was 84%. Follow up of 16 patients after appropriate therapy showed complete regression of the disease in 87.5% of cases whereas in 12.5% of cases a decrease in the extent of duodenal ulceration was noted. 相似文献

We present and validate a multi-wavelength time-domain near-infrared spectroscopy (TD-NIRS) system that avoids switching wavelengths and instead exploits the full capability of a supercontinuum light source by emitting and acquiring signals for the whole chosen range of wavelengths. The system was designed for muscle and brain oxygenation monitoring in a clinical environment. A pulsed supercontinuum laser emits broadband light and each of two detection modules acquires the distributions of times of flight of photons (DTOFs) for 16 spectral channels (used width 12.5 nm / channel), providing a total of 32 DTOFs at up to 3 Hz. Two emitting fibers and two detection fiber bundles allow simultaneous measurements at two positions on the tissue or at two source-detector separations. Three established protocols (BIP, MEDPHOT, and nEUROPt) were used to quantitatively assess the system’s performance, including linearity, coupling, accuracy, and depth sensitivity. Measurements were performed on 32 homogeneous phantoms and two inhomogeneous phantoms (solid and liquid). Furthermore, measurements on two blood-lipid phantoms with a varied amount of blood and Intralipid provide the strongest validation for accurate tissue oximetry. The retrieved hemoglobin concentrations and oxygen saturation match well with the reference values that were obtained using a commercially available NIRS system (OxiplexTS) and a blood gas analyzer (ABL90 FLEX), except a discrepancy occurs for the lowest amount of Intralipid. In-vivo measurements on the forearm of three healthy volunteers during arterial (250 mmHg) and venous (60 mmHg) cuff occlusions provide an example of tissue monitoring during the expected hemodynamic changes that follow previously well-described physiologies. All results, including quantitative parameters, can be compared to other systems that report similar tests. Overall, the presented TD-NIRS system has an exemplary performance evaluated with state-of-the-art performance assessment methods. 相似文献

Of 935 faecal samples studied over a period of one year, V. cholerae 01 was isolated from 102 samples (10.9%). All the strains were found to be E1 Tor Ogawa. The strains belonging to the phage types 2 and 4 were encountered in our study, type 2 being the highest (76.5%). The sensitivity pattern of all strains to the commonly used antibiotics was determined. Strains sensitive to gentamicin (92.2%), nalidixic acid (85.3%), kanamycin (83.3%), cotrimoxazole (80.4%) and chloramphenicol (75.5%) were observed. Out of the total, 36.3%, 29.4% and 28.4% of V. cholerae strains were found to be resistant to ampicillin, streptomycin and tetracycline respectively. V. cholerae was isolated throughout the year indicating the endemicity of cholera in Bombay. 相似文献

Objective: Cleidocranial dysostosis (CCD) is a skeletal disorder associated with dental anomalies such as failure or delayed eruption of permanent teeth and multiple impacted supernumerary or permanent teeth. Absence of cellular cementum at the root apex is presumed to be one of the factors for failure or delayed eruption. The aim of this study was to analyze the root cementum of supernumerary(S) and permanent teeth (P) of a CCD patient and to compare the findings with those of normal individuals with special emphasis on delayed eruption. Materials and Methods: Ground sections of 12 extracted teeth (9S + 3P) of a CCD patient and 12 teeth of normal individuals (5S + 7P) were taken for the study. The sections were longitudinal and 50 microm thick. Root characteristics were recorded with the aid of a light microscope. Results: The absence of apical cellular cementum, increased root resorption and increased percentage of the gap type of cemento-enamel (C-E) junctions were significant findings noted both in the supernumerary and permanent teeth of the CCD patient. Conclusion: The presumption of cellular cementum is essential for tooth eruption is not supported by the findings of the present study. Delayed exception could be attributed to various other factors like mechanical obstruction, reduced serum alkaline phosphatase levels etc. Also, the significance of the increased percentage of the gap type of C-E junctions and its role in tooth eruption has to be further evaluated. 相似文献
