Do personal traits of the leader predict differences in leader and subordinate evaluations of leader effectiveness:A study in the banking industry in Ethiopia

Purpose:  This study aims to examine whether the internal locus of control, self-esteem and leadership self-efficacy can predict differences in self–other rating agreement on leader effectiveness. First, the authors predicted that the greater the internal locus of a leader the more their self-rating will be in agreement with others' rating of them (1a). Second, the authors proposed that the greater the self-esteem of a leader the more their self-rating will be in discrepancy with others' rating (1b). Third, the authors hypothesized that the greater the self-efficacy of a leader the more their self-rating will be in agreement with others' rating (1c).  Design/methodology/approach:  To test the hypotheses, multisource data were collected from 128 banking leaders (who responded about different aspects of leadership self-efficacy, internal locus of control, self-esteem and leadership effectiveness) and 344 subordinates (who rated their leaders' effectiveness in performing leadership tasks).Multivariate regression was performed by jointly regressing both leaders' self-ratings and subordinates' ratings as a dependent variable on internal locus of control, self-esteem and leadership self-efficacy as predictor variables.  Findings:  Self-esteem of a leader the more their self-rating will be in discrepancy with others' ratings. Originality/value: The study tried to investigate the leader-subordinate dis(agreement) on leaders’ effectiveness taking banking leaders in the Ethiopian Context. The finding of the results is crucial and important for leadership development programs

Utilization and determinants of modern family planning among women of reproductive age group in Ethiopia: results from Integrated Family Health Program.

Background: Family planning improves community health and wellbeing by helping women to space and/or limit the number of children they want until they are physically and financially prepared.Objective: The aim of this study was to assess utilization and determinants of modern family planning among women of reproductive age in Ethiopia.Methods: A cross-sectional household survey was conducted in four major regions of Ethiopia (Tigray, Amhara, Oromia and Southern Nations, Nationalities and Peoples (SNNP)) from April 28 to May 30, 2013. 2,404 women of reproductive age were interviewed Samples were selected using a two-stage stratified sampling process. Descriptive and logistic regression methods of analysis were used to analyze utilization of modern family planning and the factors associated with it.Result: The mean age of respondents’ was 28.6 years (S.D=8.67). The most commonly used methods of family planning are injectable. Multivariable analysis showed that discussion with partner/husband about family planning practice in the last 6 months (AOR=6.1, 95%CI=4.73-7.81) and respondents knew health extension workers providing family planning services (AOR=1.57, 95% CI=1.23-2.01) were significantly associated with the use of modern family planning methods.Conclusion: Results of this study revealed that the number of respondents who have discussed with husband/partner about family planning and respondents who knew the family planning service providers were high utilizers of modern family planning methods. Our findings also indicated that current use of modern family planning increases with women’s education, and creating a conductive environment for women’s education is critical. Additional efforts are required to promote modern family planning utilization, partner participation, and couple counselling for join to decision making to improve modern family planning use. Key words: Family planning, Modern methods, Utilization, Reproductive age, Partner discussio

In vitro antioksidacijska, citotoksična i antidijabetička aktivnost hidrolizata proteina iz Reevesove barske kornjače (Chinemys reevesii)

Research background. Cardiovascular diseases and diabetes are the biggest causes of death globally. Bioactive peptides derived from many food proteins using enzymatic proteolysis and food processing have a positive impact on the prevention of these diseases. The bioactivity of Chinese pond turtle muscle proteins and their enzymatic hydrolysates has not received much attention, thus this study aims to investigate their antioxidant, antidiabetic and cytotoxic activities. Experimental approach. Chinese pond turtle muscles were hydrolysed using four proteolytic enzymes (Alcalase, Flavourzyme, trypsin and bromelain) and the degrees of hydrolysis were measured. High-performance liquid chromatography (HPLC) was conducted to explore the amino acid profiles and molecular mass distribution of the hydrolysates. The antioxidant activities were evaluated using various in vitro tests, including 1,1-diphenyl-2-picrylhydrazyl (DPPH) and 2,2’-azino-bis(3-ethylbenzothiazoline-6-sulfonic acid) (ABTS), hydroxyl radical scavenging activity, reducing capacity, chelating Fe2+ and lipid peroxide inhibition activity. Antidiabetic activity was evaluated using α-amylase inhibition and α-glucosidase inhibition assays. Besides, cytotoxic effect of hydrolysates on human colon cancer (HT-29) cells was assessed. Results and conclusions. The amino acid composition of the hydrolysates revealed higher mass fractions of glutamic, aspartic, lysine, hydroxyproline and hydrophobic amino acids. Significantly highest inhibition of lipid peroxidation was achieved when hydrolysate obtained with Alcalase was used. Protein hydrolysate produced with Flavourzyme had the highest radical scavenging activity measured by DPPH (68.32%), ABTS (74.12%) and FRAP (A700 nm=0.300) assays, α-glucosidase (61.80%) inhibition and cytotoxic effect (82.26%) on HT-29 cell line at 550 µg/mL. Hydrolysates obtained with trypsin and bromelain had significantly highest (p<0.05) hydroxyl radical scavenging (92.70%) and Fe2+ metal chelating (63.29%) activities, respectively. The highest α-amylase (76.89%) inhibition was recorded when using hydrolysates obtained with bromelain and Flavourzyme. Novelty and scientific contribution. Enzymatic hydrolysates of Chinese pond turtle muscle protein had high antioxidant, cytotoxic and antidiabetic activities. The findings of this study indicated that the bioactive hydrolysates or peptides from Chinese pond turtle muscle protein can be potential ingredients in pharmaceuticals and functional food formulations.Pozadina istraživanja. Kardiovaskularne bolesti i dijabetes najčešći su uzroci smrti na svijetu. Bioaktivni peptidi dobiveni proteolizom i preradom hrane imaju pozitivan učinak na prevenciju tih bolesti. Biološka aktivnost proteina iz mišića Reevesove barske kornjače i njihovih hidrolizata nije dovoljno istražena, stoga je svrha ovoga rada bila ispitati njihovu antioksidacijsku, antidijabetičku i citotoksičnu aktivnost. Eksperimentalni pristup. Mišići Reevesove barske kornjače hidrolizirani su pomoću proteolitičkih enzima (Alcalase, Flavourzyme, tripsin i bromelain), te su mjereni stupnjevi hidrolize proteina. Aminokiselinski sastav i distribucija molekularne mase hidrolizata ispitani su pomoću visokodjelotvorne tekućinske kromatografije. Antioksidacijska aktivnost određena je različitim testovima in vitro, uključujući sposobnost uklanjanja 1,1-difenil-2-pikrilhidrazila (DPPH), 2,2’-azino-bis(3-etilbenzotiazolin-6-sumporne kiseline) (ABTS) i hidroksil radikala, keliranja Fe2+ i inhibicije lipidne peroksidacije. Antidijabetička aktivnost ispitana je testovima inhibicije α-amilaze i α-glukozidaze. Osim toga, analiziran je citotoksični učinak hidrolizata na stanice tumora debelog crijeva (HT-29). Rezultati i zaključci. Analizom aminokiselinskog sastava hidrolizata pronađeni su veći maseni udjeli glutaminske i asparaginske kiseline, lizina, hidroksiprolina te hidrofobnih aminokiselina od onih u nehidroliziranim proteinima. Hidrolizat proteina dobiven pomoću proteolitičkog enzima Alcalase bitno je inhibirao peroksidaciju lipida. Pri koncentraciji od 550 µg/mL, hidrolizat proteina dobiven pomoću enzima Flavourzyme imao je najveću sposobnost uklanjanja slobodnih radikala mjerenu pomoću DPPH (68,32 %), ABTS (74,12 %) i FRAP (A700 nm=0,300) metoda, inhibicije α-glukozidaze (61,80 %) te najveći citotoksični učinak na stanične linije HT-29 (82.26 %). Hidrolizat proteina dobiven pomoću tripsina imao je znatnu (p<0,05) aktivnost uklanjanja hidroksilnih radikala (92,70 %), a onaj dobiven pomoću bromelaina najveću aktivnost keliranja Fe2+ (63,29 %). Najveća inhibicija α-amilaze postignuta je pomoću hidrolizata proteina dobivenih djelovanjem bromelaina i enzima Flavourzyme. Novina i znanstveni doprinos. Hidrolizati proteina mišića Reevesove barske kornjače dobiveni enzimskom hidrolizom imali su veliku antioksidacijsku, citotoksičnu i antidijabetičku aktivnost. Rezultati istraživanja pokazuju da se ti hidrolizati ili peptidi zbog svojih bioaktivnih svojstava mogu upotrijebiti kao sastojak u farmaceutskim i funkcionalnim prehrambenim proizvodima

Drug and Therapeutics Committee (DTC) evolvement and expanded scope in Ethiopia [version 2; peer review: 2 approved]

As a key partner of Ministry of Health (MOH) Ethiopia, The Clinton Health Access Initiative (CHAI) had been implementing the Child Survival Project (CSP) since October 2015. Strengthening DTC was one of its focuses to improve overall supply chain management (SCM). The objective of this study are to review the evolution of DTCs in Ethiopia from their early years to current practice and identify the major driving and hindering factors for their functionality. A descriptive mixed study design was employed. The study made use of qualitative data supplemented with quantitative data, generated from both primary and secondary sources through key informant interviews and desk review methods. DTCs were introduced in Ethiopia in the early 1980s. The mandate of DTCs has been given to four different government organizations during that time. As a result, due to a lack of coordination among these organizations, its implementation was lagging. Recently, the government and its partners have given attention to DTCs. More than 5847 professionals underwent DTC training from 2016 onwards. DTC establishment in health facilities improved from 85% to 98% between 2015 and 2019 during baseline and end-line assessments carried out by CHAI/CSP. Similarly, DTC functionality in HFs improved from 20% to 63%. The CHAI/CSP regular supervision data analysis revealed that DTC establishment improved from 83% to 100% of HFs, while its functionality improved from 5% to 72% between 2016 and 2019, respectively. A chi-square test of independence examining the relationship between facility and pharmacy head training on DTCs and functionality of DTC in the same facility revealed a significant association between the two variables at p<0.0001. Conclusions: Providing consistent capacity building and availing strong monitoring and evaluation system improves functionality of DTCs. Moreover, national coordinating bodies for DTCs and similar structures at Regional Health Bureaus and woreda health offices should be established

Population and fertility by age and sex for 195 countries and territories, 1950–2017: a systematic analysis for the Global Burden of Disease Study 2017

Background Population estimates underpin demographic and epidemiological research and are used to track progress on numerous international indicators of health and development. To date, internationally available estimates of population and fertility, although useful, have not been produced with transparent and replicable methods and do not use standardised estimates of mortality. We present single-calendar year and single-year of age estimates of fertility and population by sex with standardised and replicable methods. Methods We estimated population in 195 locations by single year of age and single calendar year from 1950 to 2017 with standardised and replicable methods. We based the estimates on the demographic balancing equation, with inputs of fertility, mortality, population, and migration data. Fertility data came from 7817 location-years of vital registration data, 429 surveys reporting complete birth histories, and 977 surveys and censuses reporting summary birth histories. We estimated age-specific fertility rates (ASFRs; the annual number of livebirths to women of a specified age group per 1000 women in that age group) by use of spatiotemporal Gaussian process regression and used the ASFRs to estimate total fertility rates (TFRs; the average number of children a woman would bear if she survived through the end of the reproductive age span [age 10–54 years] and experienced at each age a particular set of ASFRs observed in the year of interest). Because of sparse data, fertility at ages 10–14 years and 50–54 years was estimated from data on fertility in women aged 15–19 years and 45–49 years, through use of linear regression. Age-specific mortality data came from the Global Burden of Diseases, Injuries, and Risk Factors Study (GBD) 2017 estimates. Data on population came from 1257 censuses and 761 population registry location-years and were adjusted for underenumeration and age misreporting with standard demographic methods. Migration was estimated with the GBD Bayesian demographic balancing model, after incorporating information about refugee migration into the model prior. Final population estimates used the cohort-component method of population projection, with inputs of fertility, mortality, and migration data. Population uncertainty was estimated by use of out-of-sample predictive validity testing. With these data, we estimated the trends in population by age and sex and in fertility by age between 1950 and 2017 in 195 countries and territories.Background Population estimates underpin demographic and epidemiological research and are used to track progress on numerous international indicators of health and development.

Measuring progress from 1990 to 2017 and projecting attainment to 2030 of the health-related Sustainable Development Goals for 195 countries and territories: a systematic analysis for the Global Burden of Disease Study 2017

Background Efforts to establish the 2015 baseline and monitor early implementation of the UN Sustainable Development Goals (SDGs) highlight both great potential for and threats to improving health by 2030. To fully deliver on the SDG aim of “leaving no one behind”, it is increasingly important to examine the health-related SDGs beyond national-level estimates. As part of the Global Burden of Diseases, Injuries, and Risk Factors Study 2017 (GBD 2017), we measured progress on 41 of 52 health-related SDG indicators and estimated the health-related SDG index for 195 countries and territories for the period 1990–2017, projected indicators to 2030, and analysed global attainment. Methods We measured progress on 41 health-related SDG indicators from 1990 to 2017, an increase of four indicators since GBD 2016 (new indicators were health worker density, sexual violence by non-intimate partners, population census status, and prevalence of physical and sexual violence [reported separately]). We also improved the measurement of several previously reported indicators. We constructed national-level estimates and, for a subset of health-related SDGs, examined indicator-level differences by sex and Socio-demographic Index (SDI) quintile. We also did subnational assessments of performance for selected countries. To construct the health-related SDG index, we transformed the value for each indicator on a scale of 0–100, with 0 as the 2·5th percentile and 100 as the 97·5th percentile of 1000 draws calculated from 1990 to 2030, and took the geometric mean of the scaled indicators by target. To generate projections through 2030, we used a forecasting framework that drew estimates from the broader GBD study and used weighted averages of indicator-specific and country-specific annualised rates of change from 1990 to 2017 to inform future estimates. We assessed attainment of indicators with defined targets in two ways: first, using mean values projected for 2030, and then using the probability of attainment in 2030 calculated from 1000 draws. We also did a global attainment analysis of the feasibility of attaining SDG targets on the basis of past trends. Using 2015 global averages of indicators with defined SDG targets, we calculated the global annualised rates of change required from 2015 to 2030 to meet these targets, and then identified in what percentiles the required global annualised rates of change fell in the distribution of country-level rates of change from 1990 to 2015. We took the mean of these global percentile values across indicators and applied the past rate of change at this mean global percentile to all health-related SDG indicators, irrespective of target definition, to estimate the equivalent 2030 global average value and percentage change from 2015 to 2030 for each indicator.Background Efforts to establish the 2015 baseline and monitor early implementation of the UN Sustainable Development Goals (SDGs) highlight both great potential for and threats to improving health by 2030.

Burden of obesity in the Eastern Mediterranean Region: findings from the Global Burden of Disease 2015 study

Mokdad AH, El Bcheraoui C, Afshin A, et al. Burden of obesity in the Eastern Mediterranean Region: findings from the Global Burden of Disease 2015 study. INTERNATIONAL JOURNAL OF PUBLIC HEALTH. 2018;63(Suppl. 1):165-176.We used the Global Burden of Disease (GBD) 2015 study results to explore the burden of high body mass index (BMI) in the Eastern Mediterranean Region (EMR). We estimated the prevalence of overweight and obesity among children (2-19 years) and adults (20 years) in 1980 and 2015. The burden of disease related to high BMI was calculated using the GBD comparative risk assessment approach. The prevalence of obesity increased for adults from 15.1% (95% UI 13.4-16.9) in 1980 to 20.7% (95% UI 18.8-22.8) in 2015. It increased from 4.1% (95% UI 2.9-5.5) to 4.9% (95% UI 3.6-6.4) for the same period among children. In 2015, there were 417,115 deaths and 14,448,548 disability-adjusted life years (DALYs) attributable to high BMI in EMR, which constitute about 10 and 6.3% of total deaths and DALYs, respectively, for all ages. This is the first study to estimate trends in obesity burden for the EMR from 1980 to 2015. We call for EMR countries to invest more resources in prevention and health promotion efforts to reduce this burden

Burden of cancer in the Eastern Mediterranean Region, 2005-2015: findings from the Global Burden of Disease 2015 Study

Fitzmaurice C, Alsharif U, El Bcheraoui C, et al. Burden of cancer in the Eastern Mediterranean Region, 2005-2015: findings from the Global Burden of Disease 2015 Study. INTERNATIONAL JOURNAL OF PUBLIC HEALTH. 2018;63(Suppl. 1):151-164.To estimate incidence, mortality, and disability-adjusted life years (DALYs) caused by cancer in the Eastern Mediterranean Region (EMR) between 2005 and 2015. Vital registration system and cancer registry data from the EMR region were analyzed for 29 cancer groups in 22 EMR countries using the Global Burden of Disease Study 2015 methodology. In 2015, cancer was responsible for 9.4% of all deaths and 5.1% of all DALYs. It accounted for 722,646 new cases, 379,093 deaths, and 11.7 million DALYs. Between 2005 and 2015, incident cases increased by 46%, deaths by 33%, and DALYs by 31%. The increase in cancer incidence was largely driven by population growth and population aging. Breast cancer, lung cancer, and leukemia were the most common cancers, while lung, breast, and stomach cancers caused most cancer deaths. Cancer is responsible for a substantial disease burden in the EMR, which is increasing. There is an urgent need to expand cancer prevention, screening, and awareness programs in EMR countries as well as to improve diagnosis, treatment, and palliative care services
