Authors: Nagaraj Gautam , Forbes John C. , Leja Joel , Foreman-Mackey Daniel , Hayward Christopher C. 
Published: June 2022

Abstract
Dust plays a pivotal role in determining the observed spectral energy distribution (SED) of galaxies. Yet our understanding of dust attenuation is limited and our observations suffer from the dust–metallicity–age degeneracy in SED fitting (single galaxies), large individual variances (ensemble measurements), and the difficulty in properly dealing with uncertainties (statistical considerations). In this study, we create a population Bayesian model to rigorously account for correlated variables and non-Gaussian error distributions and demonstrate the improvement over a simple Bayesian model. We employ a flexible 5D linear interpolation model for the parameters that control dust attenuation curves as a function of stellar mass, star formation rate (SFR), metallicity, redshift, and inclination. Our setup allows us to determine the complex relationships between dust attenuation and these galaxy properties simultaneously. Using Prospector fits of nearly 30,000 3D–Hubble Space Telescope galaxies, we find that the attenuation slope (n) flattens with increasing optical depth (τ), though less so than in previous studies. τ increases strongly with SFR, though when

, reflecting the lack of triaxiality for low-mass galaxies. Redshift evolution of dust attenuation is strongest for low-mass, low-SFR galaxies, with higher optical depths but flatter curves at high redshift. Finally, n has a complex relationship with stellar mass, highlighting the intricacies of the star–dust geometry. We have publicly released software for users to access our population model.

Abstract
We present results of a wide-field (approximately 60 × 90 pc) Atacama Large Millimeter/submillimeter Array mosaic of CO(2–1) and 13CO(2–1) emission from the molecular cloud associated with the 30 Doradus star-forming region in the Large Magellanic Cloud (LMC). Three main emission complexes, including two forming a bow-tie-shaped structure extending northeast and southwest from the central R136 cluster, are resolved into complex filamentary networks. Consistent with previous studies, we find that the central region of the cloud has higher line widths at a fixed size relative to the rest of the molecular cloud and to other LMC clouds, indicating an enhanced level of turbulent motions. However, there is no clear trend in gravitational boundedness (as measured by the virial parameter) with distance from R136. Structures observed in 13CO are spatially coincident with filaments and are close to a state of virial equilibrium. In contrast, 12CO structures vary greatly in virialization, with low CO surface brightness structures outside of the main filamentary network being predominantly unbound. The low surface brightness structures constitute ∼10% of the measured CO luminosity; they may be shredded remnants of previously star-forming gas clumps, or alternatively the CO-emitting parts of more massive, CO-dark structures.
Factors associated with bone marrow involvement in lymphoma staging bone marrow examination: A South African single-centre retrospective study
Authors: Lohlun Robert K. , Chapanduka Zivanai C. 
Published: June 2022

Background: Accurate detection of bone marrow involvement (BMI) in lymphoma is important as it signifies stage 4 disease. Staging bone marrow examination (BME), therefore, influences treatment decisions and prognostication. The prevalence of BMI depends on multiple factors at presentation including lymphoma subtype, age, sex, human immunodeficiency virus (HIV) status and haematological parameters.Aim: To determine risk factors for BMI in lymphoma staging.Setting: The study was conducted in the department of haematological pathology, Tygerberg Hospital, Cape Town, South Africa.Methods: Retrospective cross-sectional descriptive study in adult patients, reviewing BMI and associated parameters, during their initial lymphoma staging procedure between 2016 and 2019.Results: Of a total of 387 lymphoma staging cases that were evaluated, 30.0% of them showed BMI. Diffuse large B-cell lymphoma, Hodgkin lymphoma and high-grade B-cell lymphoma were the most frequent subtypes diagnosed. The highest prevalence of BMI was in low-grade lymphomas. There was a statistically significant association between BMI and advanced age, pancytopenia and bicytopenia (anaemia with leucopenia, anaemia with thrombocytopenia or leucopenia with thrombocytopenia). Bicytopenia and pancytopenia showed high positive predictive values of BMI, respectively, 61.0% and 69.0%. Human immunodeficiency virus positivity (34.6%) was not predictive of BMI across all lymphoma subtypes. Normal blood counts had a high negative predictive value for BMI.Conclusion: BME remains an important part of lymphoma staging with 30.0% of all lymphomas showing BMI.
Characterizing Medicine Quality by Active Pharmaceutical Ingredient Levels: A Systematic Review and Meta-Analysis across Low- and Middle-Income Countries

Published: June 2022

ABSTRACT.
Substandard and falsified medicines are often reported jointly, making it difficult to recognize variations in medicine quality. This study characterized medicine quality based on active pharmaceutical ingredient (API) amounts reported among substandard and falsified essential medicines in low- and middle-income countries (LMICs). A systematic review and meta-analysis was conducted using PubMed, supplemented by results from a previous systematic review, and the Medicine Quality Scientific Literature Surveyor. Study quality was assessed using the Medicine Quality Assessment Reporting Guidelines (MEDQUARG). Random-effects models were used to estimate the prevalence of medicines with < 50% API. Among 95,520 medicine samples from 130 studies, 12.4% (95% confidence interval [CI]: 10.2–14.6%) of essential medicines tested in LMICs were considered substandard or falsified, having failed at least one type of quality analysis. We identified 99 studies that reported API content, where 1.8% (95% CI: 0.8–2.8%) of samples reported containing < 50% of stated API. Among all failed samples (N = 9,724), 25.9% (95% CI: 19.3–32.6%) reported having < 80% API. Nearly one in seven (13.8%, 95% CI: 9.0–18.6%) failed samples were likely to be falsified based on reported API amounts of < 50%, whereas the remaining six of seven samples were likely to be substandard. Furthermore, 12.5% (95% CI: 7.7–17.3%) of failed samples reported finding 0% API. Many studies did not present a breakdown of actual API amount of each tested sample. We offer suggested improved guidelines for reporting poor-quality medicines. Consistent data on substandard and falsified medicines and medicine-specific tailored interventions are needed to ensure medicine quality throughout the supply chain.

Published: June 2022

ABSTRACT.
Sierra Leone relies heavily on histidine-rich protein 2–based diagnostics for malaria because of the high transmission of Plasmodium falciparum. During the 2015 recombinant vesicular stomatitis virus (VSV)−Zaire Ebola virus envelope glycoprotein (GP) vaccine trial, 77 participants with asymptomatic Plasmodium infection were enrolled, with all but four having P. falciparum malaria. Of the 73 participants with P. falciparum malaria, one infection (1 of 73, 1.4%; 95% CI, 0.03–7.4) showed P. falciparum with a pfhrp3 single deletion, and two P. falciparum infections (2 of 73, 2.7%; 95% CI, 0.03–9.6) showed pfhrp2/pfhrp3 dual deletions. This study shows evidence of pfhrp2- and pfhrp3-deleted parasites in Freetown, Sierra Leone. Additional studies for more precise estimates of prevalence are warranted.

The utilization of insects as feed has witnessed dramatic inclusion in livestock and aquaculture diets. The farming of cockroach (Periplaneta americana) is gaining acceptance among industries. However, research on its use in livestock and fish nutrition is scanty. This study aimed at investigating the growth of Clarias gariepinus juveniles fed cockroach insect meal (CIM) as fishmeal (FM) replacer. One hundred and fifty Clarias gariepinus juveniles (6.29 ± 0.06 g) were stocked at 10 fish/tank/replicate and fed 40% crude protein diets formulated thus: Diet 1 (0% CIM; control), Diet 2 (25% CIM), Diet 3 (50% CIM), Diet 4 (75% CIM) and Diet 5 (100% CIM). Fish were fed at 5% of their body weight twice daily for 56-day experimental period. The results showed that final weight, mean weight gain, specific growth rate, protein efficiency and food conversion ratios of fish fed 25 and 50% insect meal-based diets were not significantly different (p>0.05) from those treated with the control diet. Survival rates were not significantly different in all dietary treatments. Quadratic regression analysis revealed that insect meal can be used at up to 58% inclusion level in diets of C. gariepinus juveniles for optimal growth.

Published: June 2022

Fatty acid compositions of the lipids extracted from various fish feeds (Eco-float, Blue-crown, Uncle - frances, Triton, Stretting, Crown, Jik, Shaldac, Solace, Coppens, Vital, Local sinking, Local feed, Aqualis and Local floating) vended in Lagos State were determined. These feeds were designated as Feeds A to O respectively. Feed samples were procured from major fish feed markets and fish farms within Lagos metropolis and transported to the laboratory for analysis. Methylation was carried out after oil extraction to convert the fats to their methyl esters and the fatty acids methyl esters (FAME) were separated by gas chromatography. Fatty acids were analysed using a HP Agilent 5890 system gas chromatograph equipped with SP-2330 and a flame ionization detector (FID). Results revealed that the highest values for polyunsaturated fatty acid (PUFA), saturated fatty acid (SFA) and ∑n-3 unsaturated fatty acid (HUFA) were 58.26% in feed F, 38.7% in feed M and 3.59% in feed N respectively while the lowest values for PUFA (19.76%) and SFA (15.53%) were recorded in feeds M and J respectively. The results also showed that, though feed samples were high in monounsaturated fatty acid (MUFA) (55- 22%) and PUFA (58-19%), they were low in n-3 HUFA {eicosapentaenoic acids (EPA, 20:5n-3) and docosahexaenoic acids (DHA, 22:6n-3)} with the values of 0.3-3%. The shortfall in EPA and DHA of these feeds may imply that fish fed these feeds may be nutritionally deficient in these fatty acid compositions. Thus, further manipulation may be needed to improve the value of these feeds in terms of EPA and DHA.

O livro didático desde seu aparecimento é dado com um dos principais materiais didáticos usados da escola. Esse estudo qualitativo e documental teve como premissa análise de conteúdo dos livros didáticos adotados para o Ensino Fundamental, pautando-se não apenas pelo conteúdo explícito, mas a análise do currículo oculto e da invisibilidade de discursos e diferentes visões históricas e legais sobre as diversidades familiares, religiosas e étnico-raciais. Destacou-se como objetivo geral - compreender como são retratadas as diversidades familiar, religiosa e étnico-racial nos livros didáticos do Ensino Fundamental e objetivos específicos - identificar as formas de retratação das diversidades, mapear boas experiências em livros e materiais didáticos que tratem da diversidade familiar, religiosa e étnico-racial e analisar os discursos encontrados nos livros didáticos sobre os temas. A metodologia de seleção e análise foi realizada sem sete etapas. O método seguiu os preceitos da análise de conteúdo apresentas por Bardin (2016). Os resultados da coleta foram organizados em quatro quadros e divididos por categorias: 1. Diversidade familiar; 2. Diversidade étnico-raciais; 3. Deficiências e; 4. Diversidade religiosa. Concluiu-se que de forma geral que os livros trazem consigo apresentam lentos avanços, já que antigamente essas questões eram pouco abordadas e quando eram representadas, apresentavam-se de forma preconceituosa.

La educación posibilita la integración de la mujer al campo laboral. La maternidad por su parte, propicia la deserción escolar. México ocupa el primer lugar, según la OCDE, en embarazos adolescentes lo que afecta las posibilidades de estas de continuar su educación. Esta investigación de corte cualitativo analiza los desafíos de madres estudiantes del nivel medio superior y superior para permanecer en la escuela. Se realizaron cuatro grupos focales con 24 madres estudiantes de ambos niveles. Entre los resultados se encontró que la dificultad más importante es la disponibilidad de recursos económicos. La maternidad cambia sus prioridades. Cuando el padre es proveedor hay poco ingreso y grandes presiones. Estas chicas tienen una carga de estrés fuerte que afecta su salud física y emocional. La familia es el principal apoyo, cuando asumen el compromiso, pero existe un reclamo velado: “es tu culpa”. En conclusión estas estudiantes con hijos piden apoyo y acompañamiento en este proceso.
