Background Sentiments and opinions regarding COVID-19 and the COVID-19 vaccination on Indonesian-language Twitter are scarcely reported in one comprehensive study, and thus were aimed at our study. We also analyzed fake news and facts, and Twitter engagement to understand people’s perceptions and beliefs that determine public health literacy. Methods We collected 3,489,367 tweets data from January 2020 to August 2021. We analyzed factual and fake news using the string comparison method. The difflib library was used to measure similarity. The user’s engagement was analyzed by averaging the engagement metrics of tweets, retweets, favorites, replies, and posts shared with sentiments and opinions regarding COVID-19 and COVID-19 vaccination. Result Positive sentiments on COVID-19 and COVID-19 vaccination dominated, however, the negative sentiments increased during the beginning of the implementation of restrictions on community activities (PPKM). The tweets were dominated by the importance of health protocols (washing hands, keeping distance, and wearing masks). Several types of vaccines were on top of the word count in the vaccine subtopic. Acceptance of the vaccination increased during the studied period, and the fake news was overweighed by the facts. The tweets were dynamic and showed that the engaged topics were changed from the nature of COVID-19 to the vaccination and virus mutation which peaked in the early and middle terms of 2021. The public sentiment and engagement were shifted from hesitancy to anxiety towards the safety and effectiveness of the vaccines, whilst changed again into wariness on an uprising of the delta variant. Conclusion Understanding public sentiment and opinion can help policymakers to plan the best strategy to cope with the pandemic. Positive sentiments and fact-based opinions on COVID-19, and COVID-19 vaccination had been shown predominantly. However, sufficient health literacy levels could yet be predicted and sought for further study.

RESUMO: Partindo da leitura crítica de obras de histórias da filosofia africana, de introdução às filosofias africanas e antologias especializadas nessa área, este artigo objetiva problematizar a posição paradoxal de denúncia da exclusão intelectual do pensamento africano, ao mesmo tempo em que finda por promover uma marginalização epistêmica das filósofas africanas. Ao mostrar que o núcleo fundamental das obras de introdução e divulgação do pensamento filosófico africano está estruturado em torno de um androcentrismo da produção desses materiais, o artigo soma-se aos esforços de radicalizar a perspectiva anti-excludente da prática das filosofias africanas, apontando para a necessidade de revisão crítica desses trabalhos de divulgação e do fazer formativo em filosofia.
PALAVRAS-CHAVE: Filosofia Africana; Marginalização epistêmica de mulheres; Filósofas africanas; Androcentrismo.

ABSTRACT: Starting from a critical reading of works on the history of African philosophy, introduction to African philosophies and anthologies specialized in this area, this paper aims to problematize the paradoxical position of denouncing the intellectual exclusion of African philosophical thought, while ending up promoting an epistemic marginalization of female philosophers African. By signaling that androcentrism structures the fundamental core of works that introduce and disseminate African philosophical thought, the paper adds to the efforts to radicalize the anti-exclusionary perspective of the practice of African philosophies, pointing to the need for a critical review of these diffusion works and training in philosophy.

LA NOTION D’INTÉRÊTS COLLECTIFS DANS LE POST-MARXISME ET LA TRADITION RADICALE NOIRE
Authors: Ajari Norman 
Published: November 2023

Cet article élabore le constat que la philosophie sociale du XXe siècle se caractérise par un reflux progressif du concept d’intérêts de classe. L’analyse de Georg Lukacs de la position-clef du prolétariat au sein des rapports sociaux capitaliste a été matricielle pour la philosophie de la première École de Francfort. Cependant, en rattachant le concept d’intérêts collectifs à la connaissance davantage qu’a la politique, Habermas en entame la déconstruction. Elle sera achevée avec les efforts de Laclau et Mouffe pour condamner le concept d’intérêts comme relevant d’un essentialisme de classe. A la même période, au contraire, au sein de la tradition radicale noire, la notion d’intérêts appliquée aux populations afrodescendantes conserve toute sa pertinence. Les œuvres d’Aimé Césaire et de Frantz Fanon en fournissent la preuve.
EPISTEMICÍDIO E NORMA EPISTÊMICA

Este artigo tem como objetivo refletir acerca do epistemicídio e a norma epistêmica como estratégias de dominação colonialista por meio do exercício do poder sobre o saber e o ser em sociedades colonizadas, um debate que se enquadra igualmente no campo da epistemologia social, particularmente na temática sobre o “silenciamento epistêmico”. O epistemicídio ou as “injustiças epistêmicas”, junto ao genocídio em nosso território afro-pindorâmico, se caracteriza com continuadas tentativas de extermínio das tradições, saberes e suas tecnologias, sustentada por vários mecanismos de silenciamento, dentre eles, temos a norma epistêmica com base na “razão universal” ao exemplo do reducionismo e a analiticidade. Porém, como nossas/os ancestrais (culturais e epistêmicos) andamos nas encruzas da desobediência epistêmica, nas veredas da pluriversalidade, provincialização e da razoabilidade das racionalidades, “costurando” saberes dentro de uma estrutura “arqueológica de conhecimento” que é determinada, muita das vezes, por uma ecologia do saber que tem como barômetro um “local epistêmico” hegemônico desde a semântica ao processo de legitimação ontológica, ao exemplo das “eurofilosofias”; isto é, marginalização das “filosofias e ciências” da alteridade como as afro-pindorâmicas e indo-islâmicas.

Antireflection (AR) coatings are essential to the performance of optical systems; without them, surface reflections increase significantly at steep angles and become detrimental to the functionality. AR coatings apply to a wide range of applications from solar cells and laser optics to optical windows. Many times, operational conditions include high temperatures and steep angles of incidence (AOIs). The implementation of AR coatings is extremely challenging in these conditions. Nanoporous coatings made from high-temperature-tolerant materials offer a solution to this problem. The careful selection of materials is needed to prevent delamination when exposed to high temperatures, and an optimal optical design is needed to lower surface reflections at both the normal incidence and steep AOIs. This paper presents nanoporous silicon dioxide and hafnium dioxide coatings deposited on a sapphire substrate using oblique angle deposition by electron beam evaporation, a highly accurate deposition technique for thin films. Developed coatings were tested in a controlled temperature environment and demonstrated thermal stability at temperatures up to 800°C. Additional testing at room temperature demonstrated the reduction of power reflections near optimal for AOIs up to 70° for a design wavelength of 1550 nm. These findings are promising to help extend the operation of technology at extreme temperatures and steep angles.

Among modern optical microscopy techniques, digital lensless holographic microscopy (DLHM) is one of the simplest label-free coherent imaging approaches. However, the hardware simplicity provided by the lensless configuration is often offset by the demanding computational postprocessing required to match the retrieved sample information to the user’s expectations. A promising avenue to simplify this stage is the integration of artificial intelligence and machine learning (ML) solutions into the DLHM workflow. The biggest challenge to do so is the preparation of an extensive and high-quality experimental dataset of curated DLHM recordings to train ML models. In this work, a diverse, open-access dataset of DLHM recordings is presented as support for future research, contributing to the data needs of the applied research community. The database comprises 11,760 experimental DLHM holograms of bio and non-bio samples with diversity on the main recording parameters of the DLHM architecture. The database is divided into two datasets of 10 independent imaged samples. The first group, named multi-wavelength dataset, includes 8160 holograms and was recorded using laser diodes emitting at 654 nm, 510 nm, and 405 nm; the second group, named single-wavelength dataset, is composed of 3600 recordings and was acquired using a 633 nm He–Ne laser. All the experimental parameters related to the dataset acquisition, preparation, and calibration are described in this paper. The advantages of this large dataset are validated by re-training an existing autofocusing model for DLHM and as the training set for a simpler architecture that achieves comparable performance, proving its feasibility for improving existing ML-based models and the development of new ones.

Aim
To investigate the effects of exercise on salivary concentrations of inflammatory markers by analyzing a panel of 25 inflammatory markers in subjects who had participated in bicycle ergometer tests varying in workload and hydration status.

Methods
Fifteen healthy young men (20–35 years) had performed 4 different exercise protocols of 1 hour duration in a randomly assigned cross-over design, preceded by a rest protocol. Individual workloads depended on participant’s pre-assessed individual maximum workload (Wmax): rest (protocol 1), 70% Wmax in hydrated (protocol 2) and dehydrated (protocol 3) state, 50% Wmax (protocol 4) and intermittent 85%/55% Wmax in 2 min blocks (protocol 5). Saliva samples were collected before (T0) and immediately after exercise (T1), and at several time points after exercise (2 hours (T3), 3 hours (T4), 6 hours (T5) and 24 hours (T6)). Secretory Leukocyte Protease Inhibitor (SLPI), Matrix Metallopeptidase-9 (MMP-9) and lactoferrin was analyzed using a commercial ELISA kit, a panel of 22 cytokines and chemokines were analyzed using a commercial multiplex immunoassay. Data was analyzed using a multilevel mixed linear model, with multiple test correction.

Results
Among a panel of 25 inflammatory markers, SLPI concentrations were significantly elevated immediately after exercise in all protocols compared to rest and higher concentrations reflected the intensity of exercise and hydration status. MMP-9 showed a significant increase in the 70% Wmax dehydrated, 50% Wmax and intermittent protocols.

Conclusions
Salivary concentrations of SLPI and MMP-9 seem associated with exercise intensity and hydration status and may offer non-invasive biomarkers to study (local) inflammatory responses to different exercise intensities in human studies.

Published: November 2023

Background
Cardiometabolic risk factors (impaired fasting glucose, abdominal obesity, high blood pressure, dyslipidemia) cluster in children, may predict adult disease burden, and are inadequately characterized in South American children.

Objectives
To quantify the burden of cardiometabolic risk factors in South American children (0–21 years) and identify knowledge gaps.

Methods
We systematically searched PubMed, Google Scholar, and the Latin American and Caribbean Health Sciences Literature via Virtual Health Library from 2000–2021 in any language. Two independent reviewers screened and extracted all data.

Results
179 studies of 2,181 screened were included representing 10 countries (n = 2,975,261). 12.2% of South American children experienced obesity, 21.9% elevated waist circumference, 3.0% elevated fasting glucose, 18.1% high triglycerides, 29.6% low HDL cholesterol, and 8.6% high blood pressure. Cardiometabolic risk factor definitions varied widely. Chile exhibited the highest prevalence of obesity/overweight, low HDL, and impaired fasting glucose. Ecuador exhibited the highest prevalence of elevated blood pressure. Rural setting (vs. urban or mixed) and indigenous origin protected against most cardiometabolic risk factors.

Conclusions
South American children experience high rates of obesity, overweight, and dyslipidemia. International consensus on cardiometabolic risk factor definitions for children will lead to improved diagnosis of cardiometabolic risk factors in this population, and future research should ensure inclusion of unreported countries and increased representation of indigenous populations.

Published: November 2023

Objectives
To describe the extent to which caregivers’ emotional and communication needs were met during pediatric emergency department (PED) visits. Secondary objectives included describing the association of caregiver emotional needs, satisfaction with care, and comfort in caring for their child’s illness at the time of discharge with demographic characteristics, caregiver experiences, and ED visit details.

Study design
Electronic surveys with medical record review were deployed at ten Canadian PEDs from October 2018 –March 2020. A convenience sample of families with children <18 years presenting to a PED were enrolled, for one week every three months, for one year per site. Caregivers completed one in-PED survey and a follow-up survey, up to seven days post-visit.

Results
This study recruited 2005 caregivers who self-identified as mothers (74.3%, 1462/1969); mean age was 37.8 years (SD 7.7). 71.7% (1081/1507) of caregivers felt their emotional needs were met. 86.4% (1293/1496) identified communication with the doctor as good/very good and 83.4% (1249/1498) with their child’s nurse. Caregiver involvement in their child’s care was reported as good/very good 85.6% (1271/1485) of the time. 81.8% (1074/1313) of caregivers felt comfortable in caring for their child at home at the time of discharge. Lower caregiver anxiety scores, caregiver involvement in their child’s care, satisfactory updates, and having questions adequately addressed positively impacted caregiver emotional needs and increased caregiver comfort in caring for their child’s illness at home.

Conclusion
Approximately 30% of caregivers presenting to PEDs have unmet emotional needs, over 15% had unmet communication needs, and 15% felt inadequately involved in their child’s care. Family caregiver involvement in care and good communication from PED staff are key elements in improving overall patient experience and satisfaction.

Introduction
The lack of standardized methods for detecting biofilms continues to pose a challenge to microbiological diagnostics since biofilm-mediated infections induce persistent and recurrent infections in humans that often defy treatment with common antibiotics. This study aimed to evaluate diagnostic parameters of four in vitro phenotypic biofilm detection assays in relation to antimicrobial resistance in aerobic clinical bacterial isolates.

Methods
In this cross-sectional study, bacterial strains from clinical samples were isolated and identified following the standard microbiological guidelines. The antibiotic resistance profile was assessed through the Kirby-Bauer disc diffusion method. Biofilm formation was detected by gold standard tissue culture plate method (TCPM), tube method (TM), Congo red agar (CRA), and modified Congo red agar (MCRA). Statistical analyses were performed using SPSS version 17.0, with a significant association considered at p<0.05.

Result
Among the total isolates (n = 226), TCPM detected 140 (61.95%) biofilm producers, with CoNS (9/9) (p<0.001) as the predominant biofilm former. When compared to TCPM, TM (n = 119) (p<0.001) showed 90.8% sensitivity and 70.1% specificity, CRA (n = 88) (p = 0.123) showed 68.2% sensitivity and 42% specificity, and MCRA (n = 86) (p = 0.442) showed 65.1% sensitivity and 40% specificity. Juxtaposed to CRA, colonies formed on MCRA developed more intense black pigmentation from 24 to 96 hours. There were 77 multi-drug-resistant (MDR)-biofilm formers and 39 extensively drug-resistant (XDR)-biofilm formers, with 100% resistance to ampicillin and ceftazidime, respectively.

Conclusion
It is suggested that TM be used for biofilm detection, after TCPM. Unlike MCRA, black pigmentation in colonies formed on CRA declined with time. MDR- and XDR-biofilm formers were frequent among the clinical isolates.
Quality of measuring devices enclosed with paediatric oral liquid dosage forms of medicines registered in Sri Lanka
Authors: Nadeshkumar Abarna , Sathiadas Gitanjali , Sri Ranganathan Shalini 
Published: November 2023

Introduction
Oral liquid dosage forms remain popular in several middle income countries. The accuracy of liquid dosage form dosing depends on the accuracy and availability of measuring devices. Lack of quality oral liquid measuring devices will lead to medication errors. Hence there is an urgent need to describe the quality of manufacturer supplied measuring devices enclosed with paediatric oral liquid dosage forms currently registered in Sri Lanka.

Methodology
Standards for measuring devices were developed after a detailed literature search. Multidisciplinary panel rated each standard for the necessity criteria on a 9 point Likert scale. Standards with overall panel median score of ≥ 7 with agreement were selected. A cross-sectional study was done. All the measuring devices, labels and instructions enclosed with the registered products were assessed against the standards developed. Three volumes of liquid antibacterials were measured using the enclosed measuring device. Accuracy of the volumes was measured.

Results
Of the total products (n = 202) only 126 were packed with a dosing device. Around quarter of the oral liquid dosage forms (n = 36) did not have a measuring device. More than half of the measuring devices aligned with all the standards developed. Out of 44 oral liquid paediatric antimicrobials measuring cups (n = 25, 56.8%, 95% CI: 41%-72%) were enclosed more and less error was seen with measuring cups.

Conclusion
The quality of oral liquid measuring devices were not satisfactory. Quality could be further improved if the regulatory body request the manufactures/importers to adhere to the standards developed. Correct volumes were not measured using the measuring devices provided with the liquid antimicrobial agents
