Branches of science such as epidemiology, clinical epidemiology, statistics and various statistical methods are by ground for activity of epidemiological-manager indicators. Incidence and prevalence are numbered among epidemiological-manager indicators. In condition of hospital Pelhřimov are these indicators written, analyzed and predicated for department of hospitalized in years 2005 -- 2007. At the same time is appraised use of capacities department of hospitalized, is made analyse and estimation of most often treated diagnosis and is watched progress their average time of treatment. The watching indicators are by one of series others records for manager decision-making by control of hospital.

The aim of this thesis is to analyze the tax effects of various forms of remuneration, with a focus on employee benefits. The thesis is structured into three chapters. In the first chapter there is a definition of labor law relationship, it's participants, rewards and demands that are placed on them. An extensive part describes employee benefits, it's legislative regulation, classification and trends in this area. The second chapter describes taxation of income from employment and compulsory contributions to social and health insurance systems. There is also a description of tax and contribution liability of employee benefits. The third chapter attends to the description of employee benefits in ČSOB Pojišťovna, a.s. and analyses the impact of replacement these employee benefits with monetary income by employees with different level and structure of total gross income. This replacement reduces the total net income by all employees and the specific impact depends on the factors that affect the tax burden. It is influenced by various structural elements of tax or insurance and the rations of income to which they are applied (ie exemption or taxation).

Magister Scientiae (Physiotherapy) - MSc(Physio) / Dance movements requires explosive power, sustained effort and both local and general endurance. Musculoskeletal injuries (MSI) are the most frequent medical problems among dancers in ballet, which is partly owing to inadequate training and dancers not being properly prepared for the demands of the dance performance. The purpose of the present study was to determine the cumulative incidence of musculoskeletal injuries amongst student dancers at TUT. The study used a prospective, cohort design. A total of 49 student dancers at Tshwane University of Technology (TUT) were followed up over 16 weeks in the 2007 academic year. The student dancers completed a questionnaire about previous injuries, and factors influencing injuries. Of the 49 student dancers, 41 (83%) consent to participate. There were 10 cumulative injuries incurred by 41 student dancers over 16 weeks period i.e. 7.1 %, 0.06 injuries incurred per student month at risk.The main limitations to this study were small sample size and possible reporting biases. Further research should aim to standardize injury definitions and classifications.

In longitudinal cohort studies, potential risk factors are measured at baseline, subjects are followed over time, and disease endpoints are ascertained via extensive surveillance. Individual follow-up time is from baseline to the event, if one is observed during the study period. Follow-up time is censored for subjects who are not observed to have the event during the study period, at the end of the study period for subjects who remain event-free, but during the study period for subjects who leave the study early by choice or by mortality, or whose last evaluation was before the end of the study. Survival analytic techniques are unique in that the unit of analysis is not the individual but the person-time contributed by the individual. Surveillance in longitudinal studies is generally quite rigorous. Subjects are examined in waves and their event status is ascertained. Surveillance continues between waves, and events come to the attention of the investigator. If there is a long time between waves, analyses can be conducted on all available data, with non-events censored early at the last examination and events followed beyond the general examination to the incident event. Motivated by analyses using the Framingham Heart Study (FHS) with cardiovascular endpoints, we consider four censoring methods for non-events and evaluate their impact on estimates of incidence, and on tests of association between risk factors and incidence. We further investigate the impact of early censoring of non-events (as compared to events) under various scenarios with respect to incidence estimation, robustness, and power using a simulation study of Weibull survival models over a range of sample sizes and distribution parameters. Our FHS and simulation investigations show early censoring of non-events causes over estimation of incidence, particularly when the baseline incidence is low. Early censoring of non-events did not affect the robustness of the Wald test [Ho: Hazard Ratio (HR) =1]. However, in both the FHS and over the range of simulation scenarios, under early censoring of non-events, estimates of HR were closer to the null (1.0), and the power to detect associations with risk factors was markedly reduced.

The National Cancer Registry (NCR) of South Africa publishes pathology-based cancer incidence in the country and is the main cancer data source. The data published by the NCR have been used extensively in the development of the draft national guidelines for cancer prevention and control as well as for cancer research. The list of contributing pathology laboratories is fairly inclusive. As far as Oral Cancer is concerned, the Department of Oral Pathology, University of Limpopo, has however not submitted data to the NCR. It is therefore reasonable to assume that because of this, a large proportion of histologically diagnosed oral cancers are not reflected in the NCR. Materials and methods: Data from the National Cancer Registry and the University of Limpopo, Department of Oral Pathology for the five years 1997-2001 were combined and then filtered for sites in the oral and oropharyngeal region. Age- Standardised Incidence Rates (ASIR) and the Cumulative Lifetime Risk (LR) for males and females in the different population groups were determined. Conclusion: It is possible that the total ASIR for oral and oropharyngeal cancer has increased in South Africa. The incidence of oral and oropharyngeal cancer in individuals below the age of 45 years in South Africa is higher than the global average. / Dissertation (MChD)--University of Pretoria, 2013. / Oral Pathology and Oral Biology / unrestricted

Introduction Lung cancer is the most common cause of cancer-related death in the United States (US). Tobacco smoking is a well-recognized cause of lung cancer. About 2% of the United States (US) population lives in Tennessee (TN). Nearly 21 % of TN adults are current smokers as per 2019 data, compared to 14% across the US. The percentage of smokers has historically been high in TN and its surroundings. This can be attributed to the area's socio-economic and cultural characteristics, along with large areas of tobacco farming in the region. This increases the risk of lung cancer in the TN population. Surveillance Epidemiology and End Results Program (SEER) is a collection of cancer registries across the US, covering about 35% of the US population (TN cancer registry is not a part of SEER). Our study compares lung cancer incidence and characteristics in the TN cancer registry with the SEER 18 registry. Materials and Methods Data were collected from the TN cancer registry and SEER separately for lung and bronchial cancer. Data was analyzed for different histological subtypes, age groups, gender, stage at diagnosis, and rural/urban residence. Stata and Microsoft Excel were used in data analysis. A Chi-square test was used to calculate the statistical significance. Results From 2008 to 2017, 58644 cases of lung cancer were reported in the Tennessee cancer registry. During the same period, 519112 cases were reported in the SEER registry. The most frequent histological subtype of lung cancer in TN and SEER was adenocarcinoma (frequency of 17,503 Vs. 182346), followed by squamous cell carcinoma and small cell carcinoma. Most cancers in TN and SEER were diagnosed at stage of distant metastasis (46% vs. 52% ), followed by regional metastasis, localized, and in situ (Image1). The frequency of lung cancer diagnosis was high among those older than 65 in TN and SEER (64% vs. 69%). Males had a higher incidence of lung cancer in both registries. Most lung cancers were reported in the urban area in both registries. Chronic obstructive pulmonary disease was the most commonly reported secondary diagnosis (3,099), followed by pleural effusion in the TN database; the comparable data were not available in SEER. Relative survival at 12 months and five years for lung cancer in TN were 46.6 % and 19.5 % (Vs. 46.4% and 19.9% in SEER) Discussion and Conclusion If both registries were perfect, then lung and bronchial cancer incidence will be 9241 and 6048 per million in ten years in TN and SEER, respectively. But after careful analysis, we conclude that such analysis will be erroneous. The proportion of different histological types, stage at diagnosis, age groups, and gender were in the same order in both groups. Although chi-square test values are significant for all the variables, we infer no conclusion considering the data's inherent bias. Further in-depth analysis of the data is required.

The recent study by Argamany et al1 concluded that the incidence and hospital mortality for Clostridium difficile infection (CDI) differed between major regions of the United States and across different seasonal times of the year. However, these conclusions were not supported by the data in their study because the authors based them exclusively on statistical significance without considering the effect size of their findings. The effect sizes of region and season on CDI were very low or near zero, contradicting their conclusion, as subsequently explained.
