Effect of Risk Avoidance on Performance of Devolved Governments in Kenya
Authors: Ochola Frankline , Lucas Stephen , Nyamita Micah 
Published: December 2022

Purpose: Risk avoidance are critical techniques in the elimination of threats, undertaking and submissions that can negatively influence an institution or government gains and investment decision worldwide. By halting the activity that can lead to likely problems, the chance of incurring and loss is eliminated. However, devolved system of government studies on risk avoidance are scanty in Kenya. The main purpose of the study was to investigate the effect of risk avoidance and how it influences performance of devolved governments in Kenya.
Methodology: The study was anchored on the agency and stakeholder theory. A correlational research design was used based on the nature of data collected. The study was analytical and hence it took a pragmatic philosophical reasoning. The study targeted 423 respondents in the 47 devolved governments departments in Kenya. A sample size of 381 respondents from the devolved governments departments was drawn from the targeted population using stratified sampling technique. The study used primary data from the use of questionnaires. Data was analyzed using Statistical Packages for Social Sciences version 24 utilizing inferential statistics which involved testing of the hypothesis at 95% confidence level and also descriptive statistics (frequencies, percentages, mean and standard deviation). Data was presented by use of tables.
Findings: The outcomes indicated that risk avoidance indicator had a standardized Beta coefficient of 0.341, an absolute t-value of 5.609 and p˂0.05 (0.03) which indicated that risk avoidance had a statistically considerable effect on performance of devolved governments in Kenya.
Unique Contribution to Theory, Practice and Policy: The study suggests that devolved governments and key stakeholders should upgrade, embrace and ensure that risk avoidance techniques are in place in the devolved governments so as to improve on performance of devolved government.

ABSTRACT
Uvod: Karcinom glave i vrata čini 3-5 % svih malignih oboljenja, koji je većinom zastupljen kod muškaraca. Napretkom radioterapije omogućen je optimalniji pristup u liječenju karcinoma glave i vrata, sa poboljšanim ishodom liječenja. Primjena savremenih imidžing tehnika u verifikaciji preciznosti tretmana znatno je promijenila tok radioterapije u liječenju malignih bolesti u smislu eskalacije doze na ciljni volumen uz veću poštedu zdravih struktura. Svrha rada je dokazati značaj i ulogu slikovne verifikacije CBCT imidžing metodom u preciznosti liječenja i kontroli tumora tokom tretmana.
Materijal i metode: Istraživanje je provedeno prospektivno u trajanju od 6 mjeseci, na Klinici za onkologiju, Kliničkog centra Univerziteta u Sarajevu. U studiju je uključeno 30 pacijenata sa karcinomom glave i vrata, kod kojih je primjenom slikovne verifikacije CBCT-om uočen gubitak tjelesne težine ili promjena ciljnog volumena. Pacijenti su zračeni VMAT tehnikom na linearnom akceleratoru TrueBeam.
Rezultati: Rezultati istraživanja su pokazali da je većina pacijenata bila muškog spola (19), starije životne dobi, sa karcinom larinksa koji je bio prisutan u čak 11 ispitanika. Jači nusefekti bili su prisutni samo kod 3,33% pacijenata, a najzastupljenije neželjene reakcije bile su blaga promuklost, suhoća usta, zamor, otežano gutanje. Od ukupnog broja pacijenata, kod 16 pacijenata uočeno je smanjenje volumena targeta koji je inicijalno prosječno iznosio 80,16 cm3, dok je nakon prosječno 18 frakcija zračenja iznosio 77,58 cm3, što je sigifikanto statistički dokazano (p= 0,007). Utvrđeno je smanjenje volumena lijeve parotidne žlijezde nakon reskeniranja u odnosu na inicijalnu vrijednost (17.37±7.55/16.93±7.06 cm3). Kod svih pacijenata na CBCT volumetrijskim slikama uočen je gubitak tjelesne težine.
Zaključak: Radioterapija karcinoma glave i vrata jedan je od učinkovitih modaliteta liječenja, koji moće biti praćen određenim neželjenim reakcijama. Primjena IGRT-a na osnovu kompjuterizirane tomografije konusnog snopa (CBCT), uveliko doprinosi peciznoj isporuci propisane doze zračenja, uz smanjenu toksičnost tretmana. Volumetrijski prikaz anatomskih struktura CBCT metodom, omogućio je da se promijeni tok kursa radioterapije u smislu prilagođavanja PTV margina u toku tretmana, odnosno primjenu adaptivne radioterapije.
CORPORATE GOVERNANCE (CG) AND ITS IMPLICATION ON PERFORMANCE OF DEPOSIT MONEY BANKS (DMBs) IN NIGERIA

Published: December 2022

This study examined the effects of corporate governance (CG) on performance of deposit money banks (DMBs) in Nigeria between the periods 2012-2021 (10years). The specific objective of the study is to examine the relationship between the measures of CG [Board Size (BS), Board Independence (BI), Board Gender Diversity (BGD), Audit Committee Size (ACS) and Audit Committee Independence (ACS)] and [performance of DMBs proxy with Returns on Equity (ROE)]. The data for the study would be gotten from the annual reports and accounts of the 10 DMBs on the basis of the variables under study. The type of relationship between the independent and dependent variables will be determined using descriptive statistics and correlation analysis, and the method of data analysis chosen was a multiple regression analysis using the OLS method by E-VIEW 9.0. DMBs that wish to enhance their FP, especially post covid-19, should try to reduce their BS to plus or minus ten, but with strict adherence to the regulatory guideline. This will ensure that the yearly huge expense on this is reduced and efficiency is guaranteed. This will have more positive influence on corporate performance.

Comparison of Risk Factors for Developing Liver Fibrosis in Subjects With and Without Metabolic Syndrome: A Cohort Study.
Authors: Treviño Morales Ana Karen , Martínez Garza Laura Elia , Calvo Anguiano Geovana , Villarreal Pérez Jesús Zacarías , González Peña Sandra Marlen , Lavalle González Fernando 
Published: December 2022

Background:
Metabolic syndrome (MS), a combination of diabetes, high blood pressure and obesity, is a well-known risk factor for developing non-alcoholic fatty liver disease, condition that can lead to serious liver damage such as liver fibrosis (LF), which is characterized by excessive deposition of connective tissue, progressing to cirrhosis and hepatocellular carcinoma. Nevertheless, subjects without MS may also develop LF. Non-invasive LF predictors based upon anthropometric and biochemical data have been reported.
Aim:
To compare anthropometric, genetic, and biochemical parameters in subjects with or without MS, and at risk for developing liver fibrosis.
Methods:
A randomized sample of 200 individuals was taken from the 2015 Nuevo León State Health Survey. Inclusion criteria were age ≥18 and a previously stored blood sample. According to the parameters obtained, subjects were classified as either with or without MS and their NAFLD fibrosis score was calculated considering variables such as age, BMI, glycemia, albumin, platelets, and AST/ALT ratio, to establish a high or low risk of LF. Comparisons of weight, age, BMI, blood glucose, total cholesterol, triglycerides, platelets, albumin, AST/ALT ratio, and HDL were made between groups. DNA was extracted from stored blood samples and genotyped, using q-PCR, according to variants in four genes related to: fatty acid (FA) metabolism (PNPLA3, rs738409), adipocyte differentiation (PLIN2, rs35568725), glucose metabolism (GCKR, rs1260326 and rs780094), and BMI (UCP2, rs659366). Statistical analysis was performed with SPSS v.22. A p value <0.05 was taken as level of significance.
Results:
A total of 134 subjects were included and divided into four groups (n): With MS+ high risk (35), With MS+ low risk (34), Without MS+ high risk (32), Without MS+ low risk (33). Table 1 shows the main significative findings. Higher age, low platelet count, and increased AST/ALT ratio, were significantly different in high risk subjects, independently of the presence of MS. No association between the polymorphisms and risk for fibrosis was found. In subjects at high risk for LF, statistical significance was found for high cholesterol blood levels (OR= 20.0 (95%CI 2.87;139.38) in carriers of the T allele of GCKR rs780094 polymorphism.
Conclusion:
Aging, thrombocytopenia, and increased transaminases, the last two indicators of liver disfunction, were found as important risk factors for LF in subjects without metabolic syndrome. None of the genetic variants analyzed resulted associated to risk of LF, although sample size could be a factor. GCKR rs780094 variant was found related with risk for hypercholesterolemia, even though dyslipidemia was not found associated with risk of LF in the present study.
