Background
Lassa fever (LF), a haemorrhagic illness caused by the Lassa fever virus (LASV), is endemic in West Africa and causes 5000 fatalities every year. The true prevalence and incidence rates of LF are unknown as infections are often asymptomatic, clinical presentations are varied, and surveillance systems are not robust. The aim of the Enable Lassa research programme is to estimate the incidences of LASV infection and LF disease in five West African countries. The core protocol described here harmonises key study components, such as eligibility criteria, case definitions, outcome measures, and laboratory tests, which will maximise the comparability of data for between-country analyses.

Method
We are conducting a prospective cohort study in Benin, Guinea, Liberia, Nigeria (three sites), and Sierra Leone from 2020 to 2023, with 24 months of follow-up. Each site will assess the incidence of LASV infection, LF disease, or both. When both incidences are assessed the LASV cohort (nmin = 1000 per site) will be drawn from the LF cohort (nmin = 5000 per site). During recruitment participants will complete questionnaires on household composition, socioeconomic status, demographic characteristics, and LF history, and blood samples will be collected to determine IgG LASV serostatus. LF disease cohort participants will be contacted biweekly to identify acute febrile cases, from whom blood samples will be drawn to test for active LASV infection using RT-PCR. Symptom and treatment data will be abstracted from medical records of LF cases. LF survivors will be followed up after four months to assess sequelae, specifically sensorineural hearing loss. LASV infection cohort participants will be asked for a blood sample every six months to assess LASV serostatus (IgG and IgM).

Discussion
Data on LASV infection and LF disease incidence in West Africa from this research programme will determine the feasibility of future Phase IIb or III clinical trials for LF vaccine candidates.

Published: March 2023

Background
In light of the stark inequities in HIV and sexually transmitted infections (STIs) experienced by women sex workers, empirical evidence is needed to inform accessible and sex worker-friendly models of voluntary, confidential and non-coercive HIV and STI testing. We evaluated the prevalence and structural correlates of HIV/STI testing in the last 6 months in a large, community-based cohort of women sex workers in Vancouver, Canada.

Methods
Data were drawn from an open community-based open cohort of women sex workers (January 2010-August 2021) working across diverse street, indoor, and online environments in Vancouver, Canada. Using questionnaire data collected by experiential (sex workers) and community-based staff, we measured prevalence and used bivariate and multivariable logistic regression to model correlates of recent HIV/STI testing at enrollment.

Results
Of 897 participants, 37.2% (n = 334) identified as Indigenous, 31.4% as Women of Color/Black (n = 282), and 31.3% (n = 281) as White. At enrollment, 45.5% (n = 408) reported HIV testing, 44.9% (n = 403) reported STI testing, 32.6% (n = 292) reported receiving both HIV and STI testing, and 57.9% (n = 519) had received an HIV and/or STI test in the last 6 months. In adjusted multivariable analysis, women accessing sex worker-led/specific services had higher odds of recent HIV/STI testing, (Adjusted Odds Ratio (AOR): 1.91, 95% Confidence Interval (CI): 1.33–2.75), whereas Women of Color and Black women (AOR: 0.52, 95%CI: 0.28–0.98) faced significantly lower odds of recent HIV/STI testing.

Conclusions
Scaling-up community-based, sex worker-led and tailored services is recommended to enhance voluntary, confidential, and safe access to integrated HIV/STI testing, particularly for Women of Color and Black Women. Culturally safe, multilingual HIV/STI testing services and broader efforts to address systemic racism within and beyond the health system are needed to reduce inequities and promote safe engagement in services for racialized sex workers.

Published: March 2023

Objectives
The aim of this cross-sectional study was to determine the life satisfaction of older people living in a home environment and to find out what predictors influence it.

Methods
The research involved 1,121 older people 60 years and above from the Moravian-Silesian region who live in a home environment. The short form of the Life Satisfaction Index for the Thirds Age (LSITA-SF12) was used to assess life satisfaction. The Geriatric depression scale (GDS-15), the Geriatric Anxiety Inventory Scale (GAI), The Sense of Coherence Scale (SOC-13), and the Rosenberg Self-Esteem Scale (RSES) were used to evaluate related factors. In addition, age, gender, marital status, education, social support, and subjective health assessment were evaluated.

Results
The overall life satisfaction score was found to be 36.34 (s = 8.66). The satisfaction of older people was classified into four grades: high satisfaction (15.2%), moderate satisfaction (60.8%), moderate dissatisfaction (23.4%), and high dissatisfaction (0.6%). The predictors of the longevity of the lives of older people were confirmed, both health factors (subjective health assessment, anxiety, and depression [Model 1: R = 0.642; R2 = 0.412; p<0.000]) and psychosocial factors (quality of life, self-esteem, sense of coherence, age, and social support [Model 2: R = 0.716; R2 = 0.513; p<0.000]).

Conclusion
In implementing policy measures, these areas should be emphasized. The availability of educational and psychosocial activities (e.g. reminiscence therapy, music therapy, group cognitive behavioural therapy, cognitive rehabilitation) within the community care of the older people and university of third age is appropriate to increase the life satisfaction of the older people. An initial depression screening is also required as part of preventive medical examinations to ensure early diagnosis and treatment of depression.

Abstract

Objectives
The exploration of the metabolites in the degradation pathways of vitamin D (VTD) has gained importance in recent years and simultaneous quantitation of twenty-five-hydroxy vitamin D (25(OH)D) mass concentration together with 24,25-dihydroxyvitamin D (24,25(OH)2D) has been proposed as a newer approach to define VTD deficiency. Yet, no data are available on 24,25(OH)2D biological variation (BV). In this study, we evaluated 24,25(OH)2D’s BV on the European Biological Variation Study (EuBIVAS) cohort samples to determine if analytical performance specifications (APS) for 24,25(OH)2D could be generated.

Methods
Six European laboratories recruited 91 healthy participants. 25(OH)D and 24,25(OH)2D concentrations in K3-EDTA plasma were examined weekly for up to 10 weeks in duplicate with a validated LC-MS/MS method. The Vitamin D Metabolite Ratio (24,25(OH)2D divided by 25(OH)D × 100) was also calculated at each time point.

Results
Linear regression of the mean 24,25(OH)2D concentrations at each blood collection showed participants were not in steady state. Variations of 24,25(OH)2D over time were significantly positively associated with the slopes of 25(OH)D concentrations over time and the concentration of 25(OH)D of the participant at inclusion, and negatively associated with body mass index (BMI), but not with age, gender, or location of the participant. The variation of the 24,25(OH)2D concentration in participants over a 10 weeks period was 34.6%. Methods that would detect a significant change linked to the natural production of 24,25(OH)2D over this period at p<0.05 would need a relative measurement uncertainty (u%)<14.9% while at p<0.01, relative measurement uncertainty should be <10.5%.

Conclusions
We have defined for the first time APS for 24,25(OH)2D examinations. According to the growing interest in this metabolite, several laboratories and manufacturers might aim to develop specific methods for its determination. The results presented in this paper are thus necessary prerequisites for the validation of such methods.

Control del entrenamiento con datos GPS y medidas subjetivas de fatiga y recuperación en futbolistas hondureños durante un periodo preparatorio para los Juegos Olímpicos de Tokio 2020/2021
Authors: Vasquez Bonilla Aldo Alfonso , Urrutia Sebastián , Bustamante Ariel , Romero Jorge Fabricio 
Published: March 2023

Introducción: El control de cargas de entrenamiento es importante para optimizar el rendimiento. Por lo tanto, se deben documentar metodologías que mejoren la preparación de selecciones nacionales en eventos como los juegos olímpicos.
Objetivo: Determinar si los datos del GPS en combinación con medidas subjetivas de bienestar, fatiga y recuperación son apropiados para el control de las cargas durante un periodo preparatorio para los Juegos Olímpicos.
Metodología: Participaron 22 jugadores profesionales sub-23 durante 5 microciclos y 27 sesiones de entrenamiento. Se recopilaron datos de carga externa a través de un sistema global de posicionamiento (GPS): Distancia total (DT), zonas de rendimiento Z0 (0-15 km/h), Z1 (15.1-18 km/h), Z2 (18.1-24 km/h), Z3 (>24.1 km/h)), velocidad máxima [Vmax (km/h)], aceleraciones (>2.5m/s2) y desaceleraciones (<2.5m/s2). También, se obtuvo la carga interna a través de medidas subjetivas de percepción del esfuerzo (RPE), calidad de la recuperación (TQR), predisposición para entrenar (RTT%) derivada de las variables de calidad del sueño, dolor muscular, niveles de energía, estado de ánimo, estrés, calidad de la alimentación y la salud. Luego se calculó la ratio subjetiva de fatiga-recuperación (F-R). Se aplicó un test ANOVA, análisis de componentes principales (ACP) y una regresión múltiple lineal.
Resultados: Las variables DT (p=0.00 TE=0.22), Z0 (p= 0.00 TE=0.08), Z2 (p=0.00 TE= 0.05), Vmax (p=0.00 TE=0.42), suma de aceleración y deceleración (p=0.00 TE=0.08) y valores relativos de la carga/min (p=0.00 TE=0.17) se identificaron como variables más sensibles al cambio de la carga entre microciclos. El RTT% y ratio subjetivo F-R mostraron un tamaño del efecto moderado (p=0.04 TE=0.06 y p=0.06 TE=0.06), pero fueron sensibles al cambio entre los microciclos. El ACP extrajo 15 variables GPS y 11 variables subjetivas que explicaron el 78% de la varianza de la carga de entrenamiento.
Conclusión: Utilizar datos GPS junto con medidas subjetivas implicadas en la fatiga-recuperación puede ser una buena estrategia para el control de la carga de entrenamiento en futbolistas.
Análisis ideológico de elmundo.cr: ¿antigobierno o antiPAC?
Authors: López González Ronny 
Published: March 2023

The Costa Rican newspaper elmundo.cr is mediatically suspected of an ideological position that rejects the Government and the Civic Action Party (PAC), due to its adhesion to the opposite candidate in 2018 presidential elections in Costa Rica.This analysis identified the veritable speech infiltrated into the informations of this newspaper. It also demonstrated that elmundo.cr is presented as an informative alternative in politics, but very far from the basic journalistic principles in order to give way to ideological interests through the legitimacy of a political authority that allows them to disguise themselves as an objective communication medium. This confirms that its editorial line went beyond an electoral moment.
Neuromítoszok az oktatásban – tények és törekvések
Authors: Csányi Tamás , Kälbli Katalin , Svraka Bernadett , Révész-Kiszela Kinga , Vig Julianna 
Published: March 2023

Háttér és célkitűzésekA neuromítoszok olyan tévhitek, amelyek az agyműködéssel kapcsolatos információk, jelenségek, idegtudományi eredmények félreértésén alapulnak. E tévhitek az oktatási rendszerben is elterjedtek, és sokszor kapcsolódnak össze különböző, úgynevezett neuropedagógiai elképzelésekkel, amelyek közvetlenül befolyásolhatják a gyakorlati pedagógiai munkát. Az elmúlt húsz évben egyre nagyobb figyelmet kapott az a kérdés, hogy mennyire elterjedtek a neuromítoszok, milyen tényezők befolyásolják jelenlétüket és elfogadottságukat az oktatás területén, és milyen hatást gyakorolnak a tanítási módszerekre. A kutatások egyöntetűen arra jutottak, hogy ezen mítoszok igen elterjedtek mind a pedagógusok, mind a pedagógusjelöltek körében. Ezen mítoszokra olyan fejlesztési javaslatok és terápiás eljárások épülnek, melyek hatástalanságuk miatt felesleges idő- és energiaráfordítást is jelenthetnek. Jelen tanulmány célja, hogy egyrészt három elterjedt oktatási neuromítosz tudományos alapjainak rövid áttekintésével bemutassa a jelenség súlyát, másrészt átfogóan ismertesse az oktatási neuromítoszokkal összefüggő tudományos eredményeket, a téma kutatásának jövőbeli irányait.MódszerTanulmányunk a neuromítoszokkal, ezen belül a három legelterjedtebb neuromítosszal kapcsolatos magyar és angol nyelvű szakcikkek feldolgozása alapján készült, műfajában narratív jellegű kritikai összefoglaló elemzés.EredményekHazánkban alig jelent meg tanulmány a témában. A nemzetközi szakirodalom azonban egyre szélesebb körben foglalkozik az oktatási neuromítoszokkal, amelyek közül a legelterjedtebbek (1) a tanulási stílusokkal, (2) az agyféltekei dominanciával és (3) az agyféltekei integrációval kapcsolatos mítoszok. A neuromítoszok elfogadását, illetve elutasítását elősegítő (prediktív, illetve protektív) tényezők egyaránt a vizsgálatok homlokterében állnak.KövetkeztetésekA pedagógusok, pedagógusjelöltek és pedagógusképzésben dolgozó munkatársak evidenciaalapú idegtudományi ismereteinek bővítése kulcsfontosságúnak látszik a neuromítoszokkal szembeni küzdelemben. Lényeges szerepet töltenek be az aggyal kapcsolatos korszerű ismeretek, és a neuromítoszok felismeréséhez szükséges kritikai gondolkodás.
Expected Return to Education, Schooling and Child Labor in Cote d’Ivoire
Authors: AHOUAKAN Ehouman Williams Venance 
Published: March 2023

Abstract
The paper attempts to assess whether expected returns to education affect the incidence of child labor in Côte d’Ivoire using the 2008 Households Living Standard Survey (ENV 2008) and the 2013 National Survey on Employment and Child Labor Status (ENSETE 2013). Nationally, approximately a quarter (1/4) of children belonging to the 5 to 17 age group are involved in economic activities. Child labor is a matter of concern in Côte d’Ivoire, as it interferes with schooling. We find evidence that improvement in the expected returns to education leads to regression of the likelihood that both boys and girls be involved in child labor,while it only increases girls’ probability of attendingschool. This result suggests that households' decisions to provide their children with schooling or to involve them early on the labor market are sensitive to the expected returns to education. A potential explanation of this could be found in the low expected returns to education. Indeed, many educated people in this country experience difficulties in finding decent jobs. Therefore, sound educational system and labor market reforms likely to improve the return to education could help reduce child labor and improve girls' schooling.

Conflict of Interest and Risk of Bias in Systematic Reviews on Methylphenidate for Attention Deficit Hyperactivity Disorder
Authors: Snellman Alexandra , Carlberg Stella , Olsson Louise 
Published: March 2023

Abstract
Background
Systematic reviews (SR) are crucial to evidence-based medicine, but associated conflict of interest remains under-investigated. We set out to compare disclosure of financial conflicts of interest (fCOI) of authors with publically available information and risk of bias (RoB) in SR on the effect of Methylphenidate for treatment of Attention Deficit Hyperactivity Disorder.
Methods
A librarian searched Medline, Cochrane Library, Embase and PsycInfo in December, 2020. PRISMA guidelines were adopted for selection. Two blinded researchers independently searched open websites for information on fCOI for all authors of all included SR. ´ Disclosure on fCOI was extracted from full-text versions of SR. RoB was judged using Cochrane´s tool for SR.
Results
Disclosure on fCOI was missing for 2/44 (5%) included SR. For 15 (34%) SR, at least one author disclosed fCOI, and confirmed by open websites in all cases. Authors of 27 (61%) SR disclosed no fCOI, but discordant information was publically available for 8 (30%). In all, 23/44 (55%) of SR were associated with fCOI.
RoB was high for 37/44 (84%) SR; 18 (49%) with and 19 (51%) without fCOI noticed on open websites. For the remaining 7 SR with low risk of bias, the corresponding figures were 6 (86%) with and 1 (14%) without fCOI.
Conclusion
The findings indicated an underreporting of fCOI corresponding to one third of SR disclosing no fCOI, methodological shortcomings were common, and 43/44 (98%) SR were compromised by either high RoB, or by fCOI. Similar investigations on other topics for comparison are warranted.
Evidence-Based Policy Making: Analysis and Policy Recommendations for how the Philippines can manage a Cost-Effective Clean Energy Transition.
Authors: Alexander Kane 
Published: March 2023

Abstract
The purpose of this research was to assess different scenarios for a cost-effective clean energy transition in the Philippines. This was done by using the Open Source Energy Modelling System (OSeMOSYS), which is a modelling software that can be used to project future energy capacities for a country, among other relevant factors such as capital investment and carbon emissions. The six scenarios modelled were least cost (LC), coal phase out (CPO), Philippines energy plan (PEP), combined energy plan (CEP), nationally determined contribution (NDC) and net zero (NZ). The key findings indicated that the CEP scenario was the most cost-effective scenario as the emissions are over 50% less compared to the LC scenario, as well as phasing out coal by 2050 and supporting the goals of the Philippines Development Plan. However, the ambitious NDC and NZ scenarios should be worked towards if funding can be secured to support them. For the Philippines, the main focus must be on the phasing out of coal, as well as a particular focus on certain renewables and the importance of finance, among other factors. This study therefore presents a discussion based on the results about the most crucial factors and what can be done to make an energy transition successful.
Adsorption potential of Ionic Liquid-Modified ZnO nanoparticles for highly efficient removal of azo dye: Detailed isotherms and kinetics

Published: March 2023

Abstract
In this study, bare and ionic liquid-modified nanoparticles have been synthesized using microwave irradiation method. The fabricated nanoparticles were characterized by different techniques viz. XRD, FT-IR, FESEM, and UV-Visible spectroscopy and were explored as adsorbent for effective removal of (Brilliant Blue R-250) azo dye from aqueous solutions. Various factors affecting the adsorption efficiency of synthesized nanoparticles (bare/ionic liquid-modified) such as concentration of dye, pH of reaction media, dose of nanoparticles, and reaction time, were thoroughly investigated with varying experimental conditions; on magnetic stirrer and in sonicator. The results exhibited a high adsorption efficiency of ionic liquid-modified nanoparticles for removal of dye as compared to the bare one. Also, an enhanced adsorption was observed via sonication than by magnetic stirring. Different isotherms such as Langmuir, Frendluich, and Tempkin were elaborated. Also, an evaluation of adsorption kinetics showed a linear pseudo-second-order equation for adsorption process.
