    Dylan J. McIntyre, Nicholas C. Jira, M. T. Romano, J. R. D\u27Rozario, M. Guedes_Duarte, T. Dougherty, and C.C. Ilie Herein, we investigate the behavior of vapor in confined media as it condenses into a liquid. Capillary condensation is studied in the presence of van der Waals forces. Three phases may occur in such a system: empty (no wetting occurs), film (a thin film of liquid forms), and full. We derived the grand free potential for the three phases, and the potential differences that occur in various substrate configurations. These potentials are used to explore the phase transitions, to find the triple point of a phase diagram and to show the possible coexistence between phases. By working with the potentials for film and empty phase and considering the symmetry and the boundary conditions in a gravitational free system, we obtain the shape of the meniscus of the liquid film between the two parallel plates. Other substrate shapes such as cylinders are also discussed and the meniscus is derived. We also present the wetting for the wedge. The wedge system behaves differently than planar or cylindrical systems. We discuss these differences and we present the shapes of the meniscus formed by filling for a few different substrate – liquid systems. We also discuss the phase transition between the empty and filled phase, which gives the evolution of the system. Understanding this phenomenon is especially important to the success of developing new nanoscale technologies, as surface effects become then more prevalent

    BACKGROUND: Human power is the back bone for the provision of quality health care for the population. High level of professional satisfaction among health workers earns high dividends such as higher worker force retention and patients satisfaction. There is limited amount of literature in the areas related to factors affecting job satisfaction and retention. The objective of this study was to determine the job satisfaction of health professionals working in Jimma University Specialized Hospital and factors affecting their level of satisfaction.METHOD: A cross-sectional study was conducted to determine the level and factors affecting job satisfaction and retention of health professionals working in Jimma University Specialized Hospital. The study was conducted from March to October 2009 and included all categories of health professionals working in the hospital during the study period. Data was collected using self administered questionnaire and focus group discussion. After the data was collected, it was entered into a computer and analyzed using SPSS version16.0 windows statistical software. Chi-square tests were made to evaluate association of different variables with job satisfaction, and P-value < 0.05, at 95% CI was taken as cut off point for statistical significance.RESULTS: A total of 145 health professionals have responded for the self administered questionnaire. The result showed that sixty seven (46.2%) of the health workers are dissatisfied with their job. The major reasons reported for their dissatisfaction were lack of motivation, inadequate salary, insufficient training opportunities and inadequate number of human resources. Only sixty (41.4%) health professionals were satisfied with their job, the major reasons given were getting satisfaction from helping others and professional gratification. Suggestion given by the respondents to improve job satisfaction and increase retention rate included motivation of staff through different incentives such us bonus, house allowance, salary increment, establishing good administration management system and improving hospital facilities and infrastructure.CONCLUSION: Job satisfaction of health professionals in Jimma University Specialized Hospital was found to be low. Responsible bodies should devise mechanisms to improve job satisfaction and retention of health professional so as to improve the healthcare services of the hospital.KEYWORDS: Job satisfaction, Health Workers, Jimma University Specialized Hospita

    Context: Longitudinal data on bone mineral density(BMD) in children and adolescents with Prader-Willi Syndrome (PWS) during long-term GH treatment are not available. Objective: This study aimed to determine effects of long-term GH treatment and puberty on BMD of total body (BMDTB), lumbar spine (BMDLS), and bone mineral apparent density of the lumbar spine (BMAD(LS)) in children with PWS. Design and Setting: This was a prospective longitudinal study of a Dutch PWS cohort. Participants: Seventy-seven children with PWS who remained prepubertal during GH treatment for 4 years and 64 children with PWS who received GH treatment for 9 years participated in the study. Intervention: The children received GH treatment, 1 mg/m(2)/day (congruent to 0.035 mg/kg/d). Main Outcome Measures: BMDTB, BMDLS, and BMAD(LS) was measured by using the same dual-energy x-ray absorptiometry machine for all annual measurements. Results: In the prepubertal group, BMDTB standard deviation score (SDS) and BMDLSSDS significantly increased during 4 years of GH treatment whereas BMAD(LS)SDS remained stable. During adolescence, BMDTBSDS and BMAD(LS)SDS decreased significantly, in girls from the age of 11 years and in boys from the ages of 14 and 16 years, respectively, but all BMD parameters remained within the normal range. Higher Tanner stages tended to be associated with lower BMDTBSDS (P = .083) and a significantly lowerBMAD(LS)SDS (P = .016). After 9 years of GH treatment, lean body mass SDS was the most powerful predictor of BMDTBSDS and BMDLSSDS in adolescents with PWS. Conclusions: This long-term GH study demonstrates that BMDTB, BMDLS, and BMAD(LS) remain stable in prepubertal children with PWS but decreases during adolescence, parallel to incomplete pubertal development. Based on our findings, clinicians should start sex hormone therapy from the age of 11 years in girls and 14 years in boys unless there is a normal progression of puberty

    Prevalence of pulmonary TB and spoligotype pattern of Mycobacterium tuberculosis among TB suspects in a rural community in Southwest Ethiopia

    <p>Abstract</p> <p>Background</p> <p>In Ethiopia where there is no strong surveillance system and state of the art diagnostic facilities are limited, the real burden of tuberculosis (TB) is not well known. We conducted a community based survey to estimate the prevalence of pulmonary TB and spoligotype pattern of the <it>Mycobacterium tuberculosis </it>isolates in Southwest Ethiopia.</p> <p>Methods</p> <p>A total of 30040 adults in 10882 households were screened for pulmonary TB in Gilgel Gibe field research centre in Southwest Ethiopia. A total of 482 TB suspects were identified and smear microscopy and culture was done for 428 TB suspects. Counseling and testing for HIV/AIDS was done for all TB suspects. Spoligotyping was done to characterize the <it>Mycobacterium tuberculosis </it>isolates.</p> <p>Results</p> <p>Majority of the TB suspects were females (60.7%) and non-literates (83.6%). Using smear microscopy, a total of 5 new and 4 old cases of pulmonary TB cases were identified making the prevalence of TB 30 per 100,000. However, using the culture method, we identified 17 new cases with a prevalence of 76.1 per 100,000. There were 4.3 undiagnosed pulmonary TB cases for every TB case who was diagnosed through the passive case detection mechanism in the health facility. Eleven isolates (64.7%) belonged to the six previously known spoligotypes: T, Haarlem and Central-Asian (CAS). Six new spoligotype patterns of <it>Mycobacterium tuberculosis</it>, not present in the international database (SpolDB4) were identified. None of the rural residents was HIV infected and only 5 (5.5%) of the urban TB suspects were positive for HIV.</p> <p>Conclusion</p> <p>The prevalence of TB in the rural community of Southwest Ethiopia is low. There are large numbers of undiagnosed TB cases in the community. However, the number of sputum smear-positive cases was very low and therefore the risk of transmitting the infection to others may be limited. Active case finding through health extension workers in the community can improve the low case detection rate in Ethiopia. A large scale study on the genotyping of <it>Mycobacterium tuberculosis </it>in Ethiopia is crucial to understand transmission dynamics, identification of drug resistant strains and design preventive strategies.</p

    Primrose syndrome: Characterization of the phenotype in 42 patients

    Primrose syndrome (PS; MIM# 259050) is characterized by intellectual disability (ID), macrocephaly, unusual facial features (frontal bossing, deeply set eyes, down-slanting palpebral fissures), calcified external ears, sparse body hair and distal muscle wasting. The syndrome is caused by de novo heterozygous missense variants in ZBTB20. Most of the 29 published patients are adults as characteristics appear more recognizable with age. We present 13 hitherto unpublished individuals and summarize the clinical and molecular findings in all 42 patients. Several signs and symptoms of PS develop during childhood, but the cardinal features, such as calcification of the external ears, cystic bone lesions, muscle wasting, and contractures typically develop between 10 and 16 years of age. Biochemically, anemia and increased alpha-fetoprotein levels are often present. Two adult males with PS developed a testicular tumor. Although PS should be regarded as a progressive entity, there are no indications that cognition becomes more impaired with age. No obvious genotype-phenotype correlation is present. A subgroup of patients with ZBTB20 variants may be associated with mild, nonspecific ID. Metabolic investigations suggest a disturbed mitochondrial fatty acid oxidation. We suggest a regular surveillance in all adult males with PS until it is clear whether or not there is a truly elevated risk of testicular cancer.This article is freely available via Open Access.
