In this paper, SIS and SIRS models for carrier dependent infectious diseases with immigration are proposed and analyzed by considering effects of environmental and human population related factors which are conducive to the growth of carrier population. In the modeling process, the density of carrier population is governed by a general logistic model. Further, it is assumed that the growth rate per capita and the modified carrying capacity of carrier population increase as the human population density increases. In each case, it is shown that the spread of an infectious disease increases as the carrier population density increases and the disease becomes more endemic due to immigration.

Background Handwashing is one of the most effective ways to prevent transmission of infectious diseases. A substantial body of research has examined the status and determinants of handwashing facilities in healthcare settings and schools. However, its status at home in the community, especially in developing countries, remains unclear. This study aimed to examine the availability and factors influencing basic handwashing facilities at households in Ethiopia. Method We analysed the 2016 Ethiopian Demographic and Health Survey (EDHS) data. EDHS employed a two-stage stratified cluster sampling technique. Data were collected from the lowest administrative unit (kebele). A multivariable logistic regression model that allowed cluster-level random effects was employed to examine factors that affect the availability of basic handwashing facilities (water plus soap) at households. Estimates from the regression model are reported as odds ratios (ORs) with standard errors clustered at the DHS cluster level to account for a sampling methodology. Results In our sample, only 1292 (8% [95% CI, 7.6%–8.4%]) of the households had basic handwashing facilities. Compared with head of household who had no formal education, the odds of having basic handwashing facilities was higher among head of household who completed secondary level of education (adjusted odds ratio [AOR] = 1.83; 95% CI: 1.35–2.49) and higher level of education (AOR = 2.35; 95% CI: 1.63–3.39). Odds of having basic handwashing facilities was increased with having radio (AOR = 1.32; 95% CI: 1.10–1.63) and television (AOR = 1.49; 95% CI: 1.10–2.02) at home. Households that had improved latrine were two times more likely to have basic handwashing facilities (AOR = 2.09; 95% CI: 1.56–2.80). Being at higher household wealth quintiles was associated with increased odds of having basic handwashing facilities. Conclusion Very low basic handwashing facilities was demonstrated by this study, whereas, awareness and socio-economic related factors were identified as a determinants for its availability in the household. Greater efforts are needed to increase the coverage of community-level handwashing facilities.

Abstract We conducted a restrospective cohort study of patients discharged from the emergency department at a tertiary care center with an antimicrobial prescription. More than half of the prescribed antimicrobials were misused and frequently inappropriate for various infectious diseases. In this study, we analyzed the physician-related and environment-related factors predicting misuse.

Accompanied by the rapid economic and social development, there is a phenomenon of the crazy spread of many infectious diseases. It has brought the rapid growth of the number of people infected with hand-foot-and-mouth disease (HFMD), and children, especially infants and young children’s health is at great risk. So it is very important to predict the number of HFMD infections and realize the regional early-warning of HFMD based on big data. However, in the current field of infectious diseases, the research on the prevalence of HFMD mainly predicts the number of future cases based on the number of historical cases in various places, and the influence of many related factors that affect the prevalence of HFMD is ignored. The current early-warning research of HFMD mainly uses direct case report, which uses statistical methods in time and space to have early-warnings of outbreaks separately. It leads to a high error rate and low confidence in the early-warning results. This paper uses machine learning methods to establish a HFMD epidemic prediction model and explore constructing a variety of early-warning models. By comparison of experimental results, we finally verify that the HFMD prediction algorithm proposed in this paper has higher accuracy. At the same time, the early-warning algorithm based on the comparison of threshold has good results.

Two Parameters

Analytical sensitivity and spatial resolution are important and closely related factors in x-ray microanalysis using the AEM. Analytical sensitivity is the ability to distinguish, for a given element under given conditions, between two concentrations that are nearly equal. The analytical sensitivity is directly related to the number of x-ray counts collected and, therefore, to the probe current, specimen thickness and counting time. The spatial resolution in AEM analysis is determined by the probe size and beam broadening in the specimen. A finer probe and a thinner specimen give a higher spatial resolution. However, the resulting lower beam current and smaller X-ray excitation volume degrade analytical sensitivity. A compromise must be made between high spatial resolution and an acceptable analytical sensitivity. In this paper, we show the necessity of evaluating these two parameters in order to determine the low temperature Fe-Ni phase diagram.A Phillips EM400T AEM with an EDAX/TN2000 EDS/MCA system and a VG HB501 FEG STEM with a LINK AN10 EDS/MCA system were used.

Purpose The purpose of this study was to determine the attendance and success rates for seniors in voice therapy, identify any contributing patient-related factors, and compare results to existing findings for younger patients. Method This retrospective study included information from the voice records of 50 seniors seen by the same speech-language pathologist in a private practice. Analysis of attendance and outcome data divided participants into 6 groups. Outcomes for Groups 1–3 (64% of patients) were considered successful (positive voice change), while outcomes for Groups 4–6 (36% of patients) were considered unsuccessful. These data were compared to similar data collected for younger adults in a previous study. Results The attendance and success rates for seniors in this study were higher than those previously reported for younger patients. Further consideration of patient factors revealed that reports of increased stress, Reflux Symptom Index scores > 13, and higher Voice Handicap Index functional subscale scores were significant in distinguishing between patients in the successful and unsuccessful treatment outcome groups. Conclusions The relatively high attendance and success rates among this sample of seniors suggest the desire to achieve voice improvement does not diminish with age, and chances for success in voice therapy among nonfrail seniors may be greater than for younger patients.

Subjective Reports

Abstract “Posttraumatic” headaches claims are controversial because they are subjective reports often provided in the complex of litigation, and the underlying pathogenesis is not defined. This article reviews principles and scientific considerations in the AMAGuides to the Evaluation of Permanent Impairment (AMA Guides) that should be noted by evaluators who examine such cases. Some examples in the AMA Guides, Sixth Edition, may seem to imply that mild head trauma can cause permanent impairment due to headache. The author examines scientific findings that present obstacles to claiming that concussion or mild traumatic brain injury is a cause of permanent headache. The World Health Organization, for example, found a favorable prognosis for posttraumatic headache, and complete recovery over a short period of time was the norm. Other studies have highlighted the lack of a dose-response correlation between trauma and prolonged headache complaints, both in terms of the frequency and the severity of trauma. On the one hand, scientific studies have failed to support the hypothesis of a causative relationship between trauma and permanent or prolonged headaches; on the other hand, non–trauma-related factors are strongly associated with complaints of prolonged headache.
