Endoscopic ultrasound-guided fine needle aspiration (EUS-FNA) is useful in diagnosing subepithelial lesions (SELs), and adequate tissue sampling is necessary to differentiate between benign and malignant diseases to determine therapeutic strategies. This study aimed to evaluate sampling adequacy and diagnostic performance of EUS-FNA for SELs with Franseen needles. This retrospective study enrolled 130 patients who underwent EUS-FNA with a 22-gauge needle for SELs from January 2010 to March 2021. We compared sampling adequacy and predictive factors influencing the sampling adequacy of EUS-FNA for SELs between Franseen and conventional needles. The sampling adequacy rates were 95.0% (38/40) with Franseen needles and 76.7% (69/90) with conventional needles (p = 0.011). The mean number of punctures with Franseen needles (2.80) was significantly less than that with conventional needles (3.42) (p < 0.001). In the multivariate analysis, the use of Franseen needles (p = 0.029; odds ratio [OR], 5.37; 95% confidence interval [CI], 1.18–23.36) was an independent factor influencing the sampling adequacy. Compared to conventional needles, the Franseen needle could play a vital role in accurately diagnosing SELs by yielding better sampling adequacy and reducing the number of passes.

PurposeNotwithstanding the remarkable market potential of the Nigerian economy for private investment, the current sociopolitical characteristics had necessitated a careful assessment to inform decisions in long-term investments. The purpose of this paper is therefore to evaluate the success factors that have a specific influence on private party’s performance in concession contracts in Nigeria.Design/methodology/approachRespondents involved in the study were participants in concession-based contracts in Southwestern Nigeria that included architects, estate surveyors, quantity surveyors, engineers and builders, accountants/bankers/economists and lawyers. These were selected using random and respondent-driven sampling (RDS) approaches. The research instrument adopted was a questionnaire that enlisted questions which were structured to ensure that the respondents have appropriate experience in concession-based projects and hold appropriate positions as decision-makers so as to give credence to collected data. The highest significant factors were identified through the relative significance index (RSI). By exploring factor analysis, the factors were condensed for discussion under appropriate component headings. The value of Kaiser–Meyer–Olkin (KMO, 0.755) measure of sampling adequacy tests carried out showed that the data collected were adequate for the factor analysis, and the Bartlett’s test of sphericity (χ2 = 1,799.339; df = 630; p < 0.001) was highly significant.FindingsFactors influencing private party performance clustered under eight components, namely, technical, market maturity, political, legal, finance, procurement, incentive and regulation. However, component items including level of understanding of public–private alliance transactions, stability of exchange rate and provisions for reversion of policies were found to be highly significant. On the other hand, status of domestication and implementation of international laws/codes, predictability in legal regime and enforcement and extent of jurisdictional definition of land usage were least significant.Originality/valueFindings would guide private investors in the preparation of robust investment packages that reduce risks and seemingly unavoidable opportunistic tendencies associated with public–private partnership projects in developing economies.

The aim of this study was to evaluate the anthropometric and lipid profiles of individuals being considered for bariatric surgery, taking into account the presence of the Thr54 allele of the fatty acid–binding protein-2 (FABP-2) gene (rs1799883), and dietary intake. In a cross-sectional study, 120 participants being evaluated for bariatric surgery were asked to keep 24-h dietary records (R24 h) for 3 d, and to collect a 24-h urine sample for measurement of urea (as an assessment of the adequacy of food records) during day 3 of the diet record; a fasting blood sample for laboratory and genetic evaluations was collected. When considering the whole sample, no significant differences were found; however, those who complied with the R24 h (n = 43) had more years of schooling and higher saturated fat intake, but lower weight and body mass index (BMI). When analyzing only the completers, the Thr54 allele carriers showed higher body weight (P = 0.02), BMI (P = 0.03), hip circumference (P = 0.02), basal metabolic rate (P = 0.02), and homeostatic model assessment-β (P = 0.04) compared with those who were homozygous for Ala54. When the participants complied with the R24 h, Thr54 carriers were shown to have higher anthropometric parameters and higher homeostatic model assessment-β values than those with the wild genotype, but the lipid profile resulted similar in both carriers and noncarriers. •Dietary intake must be considered to correctly analyze FABP-2 genotypes.•Thr54 allele carriers showed higher anthropometric profile and homeostatic model assessment-β.•No differences were observed in the lipid profile between the FABP-2 genotypes.

The majority of state-owned power companies (SoEs) have experienced organizational cancer for nearly three decades without showing any signs of ceasing operations. Academicians generally agree that organizational politics are to blame for the ongoing energy-generating dilemma that has plagued rising nations. Worldwide, economies rely heavily on electricity as an energy source, to the point where they would not function or even survive without it. In order to reduce unfavorable political behavior, this study examines organizational politics at the Zimbabwe Supply Authority, a SoE in charge of energy production. A sample of 1400 individuals who were chosen at random from a population of 2210 staff members participated in the study using a quantitative research approach to collect data. By the deadline, 358 completed questionnaires had been returned; however, 11 of them were rejected because they had been wrongly filled out, with a response rate of 24.78%. The data were analyzed using the statistical tool SPSS 21.0 for Windows. To ensure that the samples were adequate for factor analysis, the Kaiser-Meyer-Olkin (KMO) measure of sampling adequacy and Bartlett's Test of sphericity were applied to the data before exploratory factor analysis could be conducted on them (Field, 2007:619). The results of the study showed that bad political behavior and ineffective managerial leadership techniques had a detrimental impact on the power generation crisis. According to the report, managers should receive training on modern managerial leadership behavior, managerial methods for behavior modification, and improved communication.

In smart buildings, cooling load prediction is important and essential in the sense of energy efficiency especially in hot countries. Indeed, prediction is required in order to provide the occupant by his consumption and incite him to take right decisions that would potentially decrease his energy demand. In some existing models, prediction is based on a selected reference day. This selection depends on several conditions similarity. Such model needs deep analysis of big past data. Instead of a deep study to well select the reference day; this paper is focusing on a short sampling-rate for predicting the next state. So, this method requires less inputs and less stored data. Prediction results will be more close to the real state. In first phase, an hourly cooling load model is implemented. This model has as input current cooling load, current outside temperature and weather forecast to predict the next hour cooling consumption. To enhance model’s performance and reliability, the sampling period is decreasing to 30 minutes with respect to system dynamic. Lastly, prediction’s accuracy is improved by using previous errors between actual cooling load and prediction results. Simulations are realized in nodes located at a campus showing good adequacy with measurements.

The study was carried out to survey NCE students' perceptions on use of library course as an aid to their use of library resources in Colleges of Education in South-West Nigeria. The descriptive survey design was employed and four research questions guided the study. From a population of 60,481 students, a sample of 1,210 was drawn using the proportionate stratified sampling technique. Meanwhile, out of the 1,210 copies of the questionnaire distributed, 1,097 were fully completed (filled out) as retrieved and analyzed. It represents (90.66%) or approximately (91%) response rate and considered adequate because the standard and acceptable response rate for most studies is 60%. A questionnaire was the instrument used for data collection after validation by experts in the field, and pre-tested through Cronbach Alpha method that yielded 0.743 aggregate values. Complete data subsequently gathered from 1,097 copies of the questionnaire retrieved were analyzed by employing the statistical mean to answer the research questions and criterion mean placed at 2.50. Among the major findings of the study were: Students perceived use of library course as an aid to their use of all library resource categories examined in the study (that is, reference, reserve, circulation and serials resources). The study therefore recommends that students should be given increased opportunity to access \"use of library course programme\" as a veritable tool of enhancing their capacity for adequate use of reference resources among others in colleges of education in the region to ensure their effective integration into our 21st century society even after college life.

The role of adequate and timely immunization in the reduction of infant and childhood mortality cannot be overstated, especially in sub-Saharan Africa. This study, anchored in the Health Belief Model and Rational Choice Theory, investigated the socio­cultural factors influencing childhood immunization in the rural state of Abia, Nigeria, an area with a high infant mortality rate. A multistage sampling technique involving the random selection of 3 communities in Bende Local Government Area and the purposive selection of 433 respondents with children under the age of 5 was adopted. In-depth interviews were conducted with 13 respondents — 3 health personnel, 3 traditional birth attendants, 4 community leaders (2 men and 2 women), 2 church representatives, and the head of the health department in the local government headquarters. Findings reveal that the majority of respondents had heard about childhood immunization and largely understood its essence. Religious beliefs and the mother’s economic activities (especially when market day coincides with immunization day) were identified as major influences on immunization. More attention should be directed to providing adequate education for rural dwellers on the importance of immunization for childhood mortality reduction.

Under a federal-state cooperative program, the U.S. Bureau of Labor Statistics (BLS) publishes monthly unemployment rate estimates for its 50 states and the District of Columbia. The primary source of data for this estimation problem is the Current Population Survey (CPS). However, the CPS state unemployment rate estimates are unreliable, because the survey provides relatively few observations per state. Various federal agencies use state-level unemployment rate estimates for policy making and fund allocation. Thus it is important to improve on the CPS estimates. For this, we propose a hierarchical Bayes (HB) method using a time series generalization of a widely used cross-sectional model in small-area estimation. The proposed method is compared in detail with the corresponding HB method, which uses the HB analog of the well-known Fay-Herriot cross-sectional model. A third model based on a time series approach to repetitive surveys is found to be very hard to implement for these data; the resulting estimates are very unstable and not meaningful. If we ignore some important factors from this model, then the reduced model can be fit, but the resulting model is found to be less than adequate. Gibbs sampling is used to obtain the posterior means and variances of the state unemployment rates. Based on some diagnostic tools recently developed for hierarchical models, our proposed model emerges as the best. The coefficients of variation of the proposed HB estimates are considerably lower than those of the rival estimates.

Several countries with long-standing salt iodization programs, including Switzerland, have recently reported declining and/or low urinary iodine (UI) levels in their populations. In Switzerland, in response to studies indicating low UI levels in children and pregnant women, the salt iodine level was increased in 1998 from 15 to 20 mg/kg. Our objective was to evaluate iodine nutrition in a national sample of Swiss school children and pregnant women 8 16 months after the increase in the salt iodine level. A 3-stage probability proportionate to size cluster sampling method was used to obtain a representative national sample of 600 children aged 6-12 y and 600 pregnant women. We then measured UI in both groups, thyrotropin (TSH) in pregnant women and thyroid volume by ultrasound to determine goiter prevalence in school children. The median UI (range) of the children and pregnant women was 115 microg/l (5-413) and 138 microg/l (5-1881), respectively. The median blood TSH concentration (range) of pregnant women was 0.6 mU/l (0.2-2.1). Based on the current WHO/ICCIDD normative data for thyroid volume, none of the children were goitrous, using either age/sex-specific or BSA/sex-specific cutoffs. The iodine status of the Swiss population is once again adequate, illustrating the value of periodic monitoring and prudent adjustments to the iodine level in salt. This approach could serve as a model for countries struggling to maintain dietary iodine intake in the face of shifting dietary habits and changes in the food supply.
