Authors: Izekor O. B. , Kenneth A. I. , Koledoye G. F.
Published: August 2024

Lassa fever (LF) is prevalent in Edo State, where garri, the most important cassava product, is processed and marketed. The disease spreads through practices influenced by the beliefs and traditions of garri marketers. The study examines the mythical beliefs people hold about Lassa fever. A simple random sampling procedure was used to select 192 garri marketers. A structured interview schedule was employed to elicit quantitative data, while in-depth interviews were conducted to collect qualitative data. Gross Margin was used to determine profitability, and the qualitative data were transcribed. Garri marketing is a profitable venture with a gross margin of N80,752.22 per month. A large proportion (39.5%) of the marketers never believed in the epidemic nature of Lassa fever, attributing the disease to punishment from deities. Additionally, 44.6% indicated that the government used it to secure funding from international communities, while others believed that rats are not the cause of Lassa fever. In conclusion, some marketers hold false beliefs about the reality of Lassa fever. Expanding an effective awareness campaign to dispel myths about Lassa fever is crucial for enhancing the effectiveness of preventive measures against its spread.
Exploring Attentional Dynamics in Animated Programming Environments: Trajectories, Variability, and Predictors
Authors: Yusuf Abdullahi , Md Noor Norah , Adeyemi Yusuf Lateef
Published: August 2024

Researchers have proposed that the ability to pay attention to teachers’ instruction is a prerequisite for learning. However, meaningful learning is often challenged by the presence of rule-breaking behaviors. In this study, we argue that although students exhibit different attention-related behaviors in all instructional settings, some behaviors are unique to a typical classroom. It is still unclear what factors uniquely determine students’ attention-related behaviors in animated programming environments because of the paucity of research evidence in this area. This study investigates students’ attention-related behaviors during animated programming instruction, including attentional growth trajectory, the nature of differences in attention-related behaviors, and predictors of these behaviors. Our analysis involved 8 classroom videos that collected the programming activities of 30 university students in our previous study. The video files were annotated on a one-dimensional, continuous scale, yielding 1,920 timestamped data points. The data on attentional trajectories and differences in attention-related behaviors were analyzed using latent and multi-level growth modeling, respectively, while data focusing on the predictors of attentional processes were analyzed using the Random Forest machine learning algorithm. We found that students’ attentional growth trajectory is linear and accelerates toward on-task events. However, these behaviors vary within and between students, leading to differences in attention-related behaviors. The results also revealed that individual and instructional characteristics predict the differences in attention-related behaviors. The findings highlight the importance of structured topics, safe classroom environments, quality instructional support, and interactive multimedia objects that activate students’ memory, eliminate task difficulty, and reduce the amount of mental resources required for meaningful learning.

Authors: Mahmud Sheikh Hayath , Maruf Hasan Md. , Chandra Das Liton
Published: August 2024

The development of advancements in concrete technology might lessen the amount of natural resources destroyed, thereby reducing the pollutants released into the environment. Currently, industries produce large amounts of fly ash, which adversely affects the environment and human health. Recent studies have shown that additional cementitious materials can improve various concrete qualities. These materials include fly ash, slag, silica fume, metakaolin, rice husk, and hypo sludge. These materials not only enhance the properties of fresh and hardened concrete but also help constructors save money. The aim of this study is to determine whether thermal industrial waste can partially replace cement in concrete manufacturing. Specifically, fly ash was tested as an additional cementitious ingredient to replace conventional concrete. It was added to the cement in different amounts: 0% (fly ash-free), 5%, 10%, and 20% by weight of cement to produce the M-20 mix. Concrete mixtures were created, tested, and their compressive strengths were compared to those of conventional concrete. Results were collected up to 28 days after curing to assess the strength attributes. The use of 5% fly ash results in a decrease in strength, but it is not significant. For 5% replacement of cement, the strength was found to be 2984.57 psi, which is satisfactory.

This study implies to development of a sensitive liquid chromatography tandem mass spectrometry method. Further using this method ribociclib can be estimated in the drug formulation. Ribociclib was recently approved by the United States Food and Drug Administration in the year 2017 for metastatic and advanced breast cancer, which is used for resistant patients to endocrine therapy and it targets cyclin-dependent kinase 4 and 6 inhibitors. The stationary phase was Phenomenex C18 (50 × 4.6 mm, 3 microns), with a mobile phase combination of acetonitrile and 10 mM ammonium acetate (90:10 v/v ratio) with a flow of 0.7 ml/minutes. Ribociclib was detected using liquid chromatography-tandem mass spectrometry in positive transition at m/z 435.0. The linearity ranges between 5 and 100 ng/ml. The Ribociclib correlation coefficient (R2) was linear, with an R2 value of 0.9991. The drug had a retention time (RT) of 1.022 minutes, and a total run time of 3 minutes. According to the literature survey, there is a limited isocratic method for the selected drug hence, we developed an isocratic which is a quick, accurate, and efficient method for determining ribociclib and its formulation.
Anticancer activity of liposomal formulation co-encapsulated with coumarin and phenyl butyric acid
Authors: Allateef Ali , Shalan Naeem , Lafi Zainab
Published: August 2024

Anticancer treatments have poor pharmacokinetics, high toxicity to normal cells, and low bioavailability. As nanotechnology has advanced to a new level, many researchers have been motivated to develop a safer and more effective medication delivery method for the treatment of cancer. Nowadays, about 80% of the anticancer medications that have been approved recently are made from natural substances. This study aims to formulate liposomes loaded with coumarin (COM) and 4-phenylbutyric acid (PBA) and evaluate their antitumor effect in vitro. The liposomes were characterized using the dynamic light scattering instrument to determine their size, polydispersity, and charge. The formulated liposomes exhibited a particle size within the desired range of 100– 200 nm, with low polydispersity and suitable charge. Stability tests showed excellent stability of the liposomal formulations over 10 days in terms of size, charge, and polydispersity. High performance liquid chromatography analysis confirmed the successful encapsulation of COM and PBA within the liposomes, with high encapsulation efficiencies observed of 53%–25% for Lipo-PBA and Lipo-COM, respectively. Loading efficiency (LO%) was found to be 9%–5% for Lipo-PBA and Lipo-COM, respectively, which means the drugs were efficiently loaded within the liposome. In vitro cell viability studies demonstrated that the liposomes loaded with both COM and PBA exhibited the most effective inhibition on MDA-MB-231 breast cancer cells (30%) and A549 lung cancer cells (45%), while Lipo-COM showed potent inhibition on HT29 colorectal cancer cells (40%). Encapsulation of the drugs inside liposomes enhanced their cytotoxicity, potentially due to improved penetration into tumor cells. The findings suggest that the formulated liposomes have the potential for future clinical applications with high selectivity toward cancer cells.

Innledning:  Multisystemisk terapi (MST) er et behandlingstilbud til familier som har ungdom i alderen 12-18 år med store atferdsproblemer. Målet for behandlingen er at ungdommen skal fungere godt og uten atferdsproblemer. For noen ungdommer kan MST være et alternativ til plassering utenfor hjemmet. 
Beskrivelse av tiltaket:  I MST møter terapeuten familien hjemme, på tidspunkter som passer for familien. Behandlingsteknikker fra atferdsterapi, kognitiv atferdsterapi og handlingsrettede familieterapimodeller integreres i tiltaket. Terapien retter seg mot kjente risiko- og beskyttelsesfaktorer ved ungdommen selv, familien, skolen, venner og nærmiljø. MST legger spesielt stor vekt på å styrke foreldre/foresattes evne til å håndtere ungdommens antisosiale atferd. 
Evaluering av tiltaket:  Tiltaket har vært gjenstand for en rekke randomiserte kontrollerte forsøk, hvorav ett i Norge. Den norske studien har resultater som  antyder at tiltaket kan ha positiv effekt på enkelte utfall. Etter 2 år ble det funnet positive resultater for selvrapportert kriminell atferd, internaliserende atferd (rapportert av foreldre og lærere) samt for lærerrapportert problematferd og eksternaliserende atferd. Gjennomføring av en RCT på denne gruppen er komplisert, bla. på grunn av stor symptombelastning hos ungdommene. Den norske MST-studien har også en del metodiske svakheter som gjør resultatene usikre.
Ungsinns klassifisering: MST er et tiltak for ungdom med betydelig problemutvikling og dårlige prognoser, og som det er svært utfordrende å finne gode tiltak for. På bakgrunn av resultater fra den norske studien klassifiserer Ungsinn tiltaket som Funksjonelt virksomt på evidensnivå 3 med dokumentasjonsgrad *** .
Beskrivelse og vurdering av tiltaket: Olweusprogrammet - mot mobbing og antisosial atferd

Innledning: Olweusprogrammet er et skoleomfattende program med mål om å forebygge og redusere mobbeproblemer i skolen ved å skape et trygt og godt skolemiljø for alle elever.
Beskrivelse av tiltaket: Programmet gjennomføres på skole-, klasse- og individnivå ved å mobilisere det eksisterende sosiale miljøet ved skolen. Lærere, øvrig personell, elever og foreldre involveres i gjennomføringen av programmet. Generelt går en viktig del av programaktivitetene ut på at lærerne skal utvikle seg mer i «autoritativ» retning og at det brukes opplevelsesbaserte teknikker (for eksempel rollespill, klassemøter) for å bedre elevenes kunnskap om sosiale relasjoner.
Evaluering av tiltaket: Det er gjennomført 7 evalueringsstudier av programmet og dets forløpere i Norge. Studiene inkluderer til sammen mer enn 30.000 elever fra 275 skoler. Alle studiene viser reduksjon både i å mobbe andre elever og i å bli mobbet. Reduksjonen spenner mellom ca. 30 og 60%. Flere av studiene inkluderer oppfølgingsmålinger. To viser at mobbingen er redusert 20 mnd. etter implementering av programmet, mens en av studiene viste at det lavere nivået av mobbing også holdt seg de påfølgende 4 årene. Ingen av de norske studiene er publisert i sin helhet som vitenskapelige artikler i fagfellevurderte (peer-reviewed) journaler, men de er beskrevet i flere fagfellevurderte tidsskrift og bokkapitler. I rapporteringen av resultatene er informasjon om datautvalg og statistiske analysene noe mangelfull.
Det er gjennomført flere evalueringer av Olweusprogrammet i USA, der resultatene fra noen av studiene er tilgjengelige via publiserte artikler.  Det er positive resultater i disse studiene. Sammenlignet med de norske varierer resultatene mer på tvers av studier, aldersgrupper, etnisitet og aspekter ved mobbing. Det er også gjennomført en meta-analyse som sammenligner 24 programmer for reduksjon av mobbing i skolen. Denne kommer frem til at denne type programmer har en effekt. Olweus programmet hadde større effekter enn gjennomsnittet og forskningen ble omtalt som mer pålitelig.
Ungsinns klassifisering: Programmet klassifiseres som et dokumentert virksomt tiltak på evidensnivå 4 med dokumentasjonsgrad 5 (*****).
Beskrivelse og vurdering av tiltaket: VIP (Veiledning og Informasjon om Psykisk helse hos ungdom)

Innledning: VIP er et helsefremmende og universalforebyggende tiltak som retter seg mot elever i videregående skole, primært ungdom i alderen 16 til 17 år. Hovedmålet for programmet er å gjøre elever bedre rustet til å ta vare på sin egen psykiske helse og bli oppmerksom på hvilke hjelpetiltak de kan oppsøke ved psykiske problemer og lidelser. VIP er en av fem intervensjoner i satsningen «Psykisk helse i skolen» (www.psykiskhelseiskolen.no).
Beskrivelse av tiltaket: Tiltaket baserer seg på et undervisningsopplegg for elevene på 3+2 timer. De første 3 timene er med egen lærer der psykisk helse er tema, mens de siste to timene er et møte med helsepersonell f.eks. helsesøster. Selve gjennomføringen av tiltaket går gjennom 5 faser. Den første fasen er en opplæringskonferanse for alle ansatte i skolene og helsepersonell fra psykisk helsetjeneste. Fase 2 består av et samarbeidsmøte for de lærerne og helsepersonell som skal samarbeide i en klasse. I den tredje fasen starter arbeidet med elevene, og undervisning i psykisk helse samtidigs som det arbeides med elevheftet. Fase 4 er et klassebesøk fra fagpersonell på 2 timer. Den siste fasen (5) innebærer en årlig evaluering av tiltaket i klassene, som deretter tas opp blant kontaktlærere, administrasjon og helsepersonell som har deltatt i et oppsummeringsmøte.
Evaluering av tiltaket: Flere videregående skoler har fått opplæring og gjennomført tiltaket. Folkehelseinstituttet gjorde i 2010 en kvasi-eksperimentell effektevaluering av tiltaket, og resultatene var moderate til små, men det positive er at en såpass kortvarig skoleintervensjon hadde en effekt. Ikke bare økte ungdommenes kunnskaper, men også utfallsmål knyttet mer direkte til elevenes psykiske helse så ut til å ha en effekt.
Ungsinns klassifisering: VIP klassifiseres som et funksjonelt virksomt tiltak på evidensnivå 3, med dokumentasjonsgrad ***.
