The lived experiences of queer and trans people of color (QTPOC) youth are significantly influenced by the various environments they navigate -- including but not limited to their families, schools, neighborhoods, communities, and workplaces. QTPOC youth -- or queer and trans youth who identify as Asian American, Black/African American, Indigenous, Hispanic/Latinx, or/and multiracial -- are susceptible to multiple forms of oppression that are embedded in racism, sexism, transphobia, heterosexism, and more. This paper seeks to highlight perspectives of QTPOC youth -- particularly how intersectional identities, discrimination, and victimization influence school experiences and negative educational outcomes. We underscore three major areas that educators must be aware of when working with this subgroup: (a) common experiences for QTPOC youth; (b) QTPOC youth school experiences; and (c) psychosocial determinants affecting school violence. Furthermore, we provide recommendations to consider for working with QTPOC youth, specifically for teachers, school administrators, and families and communities.

Abstract The selection and combination of dose regimens for antimalarials involve complex considerations including pharmacokinetic and pharmacodynamic interactions. In this study, we use immediate ex vivo P. falciparum field isolates to evaluate the effect of cabamiquine and pyronaridine as standalone treatments and in combination therapy. We feed the data into a pharmacometrics model to generate an interaction map and simulate meaningful clinical dose ratios. We demonstrate that the pharmacometrics model of parasite growth and killing provides a detailed description of parasite kinetics against cabamiquine-susceptible and resistant parasites. Pyronaridine monotherapy provides suboptimal killing rates at doses as high as 720 mg. In contrast, the combination of a single dose of 330 mg cabamiquine and 360 mg pyronaridine provides over 90% parasite killing in most of the simulated patients. The described methodology that combines a rapid, 3R-compliant in vitro method and modelling to set meaningful doses for new antimalarials could contribute to clinical drug development.

Abstract Introduction Long-term exposure to high-risk human papillomavirus (Hr-HPV) is a well-known necessary condition for development of cervical cancer. The aim of this study is to screen for Hr-HPV using vaginal self-sampling, which is a more effective approach to improve women’s adherence and increase screening rates. Methods This pilot study included a total of 100 Women living with HIV (WLWHIV), recruited from the Center for Listening, Care, Animation, and Counseling of People Living with HIV in Bamako. Hr-HPV genotyping was performed on Self-collected samples using the Cepheid GeneXpert instrument. Results The median age of WLWHIV was 44 (interquartile range [IQR], 37–50) years. Approximately 92% of the study participants preferred self-sampling at the clinic, and 90% opted to receive result notifications via mobile phone contact. The overall prevalence of Hr-HPV among study participants was 42.6%, and the most frequent Hr-HPV sub-types observed were HPV18/45 (19.1%), HPV31/35/33/52/58 (13.8%), and HPV39/68/56/66 (12.8%), followed by HPV16 (5.3%), and HPV51/59 (5.3%). WLWHIV under 35 years of age had a higher frequency of Hr-HPV compared to their older counterparts, with rates of 30% versus 11.1% (p = 0.03). The duration of antiretroviral treatment showed an inverse association with Hr-HPV negativity, with patients on treatment for 15 (IQR, 10–18) years versus 12 (IQR = 7–14) years for Hr-HPV positive patients (95% CI [1.2–5.8], t = 3.04, p = 0.003). WLWHIV with baseline CD4 T-Cell counts below 200 exhibited a higher frequency of Hr-HPV compared to those with baseline CD4 T-Cell counts above 200 (17.9% versus 1.9%, p = 0.009). However, other demographics and clinical factors, such as marital status, age of sexual debut, parity, education, history of abortion, history of preeclampsia, and cesarean delivery, did not influence the distribution of Hr-HPV genotypes. Conclusion Our findings indicate that WLWHIV under the age of 35 years old exhibited the highest prevalence of Hr-HPV infection, with HPV18/45 being the most prevalent subtype. Additionally, WLWHIV with baseline CD4 T-Cell counts below 200 showed the highest infection rates.

Abstract Background Our recent studies have shown headache disorders to be very common in the central and western sub-Saharan countries of Benin and Cameroon. Here we report headache in nearby Mali, a strife-torn country that differs topographically, culturally, politically and economically. The purposes were to estimate headache-attributed burden and need for headache care. Methods We used cluster-random sampling in seven of Mali’s eleven regions to obtain a nationally representative sample. During unannounced household visits by trained interviewers, one randomly selected adult member (18–65 years) from each household was interviewed using the structured HARDSHIP questionnaire, with enquiries into headache in the last year and, additionally, headache yesterday (HY). Headache on ≥ 15 days/month (H15+) was diagnosed as probable medication-overuse headache (pMOH) when associated with acute medication use on ≥ 15 days/month, and as “other H15+” when not. Episodic headache (on

Insects can represent a valuable and cost effective source of animal feed in Africa. Recently, the interest in incorporating black-soldier fly larvae (BSFL) in animal feed has increased tremendously. However, many factors, including food neophobia and social and cultural context may affect consumers' perception of insect-technologies-derived food products. This study shed light on consumers' perception of the usage of BSFL as animal feed and consumption, buying, and commercialization of food from animals fed on BSFL in DR Congo, Mali, and Niger. We used data from 1560 consumers that were analyzed applying parametric and non-parametric tests and the generalized ordered logit model. Our findings show that about 87 % of respondents consider that consuming food from animals fed on BSFL is acceptable and 34 % accept buying eggs, fish, and meat from animals fed on BSFL. However, about 40 % of consumers recommend the label differentiation of BSF-technologies-derived food products and they also expect a lower price than conventional animal feed products. The analysis of factors driving consumers' readiness to buy BSF-derived food products have revealed that effective market penetration of BSF-technologies-derived food products could be achieved with great awareness creation, targeting farming households, married and literate heads. Furthermore, strategic communication and intensive sensitization through farmers' associations will be crucial. Finally, credit access and income diversification are also necessary to support consumers’ choices toward sustainable food habits built on bio-circular economy.

Abstract Objectives With rapid advances in ultrasound‐guided procedures, there is an unmet need for echogenic phantoms with sufficient anatomical details for artificial intelligence and ultrasound‐guided device testing. We developed a method for creating neck phantoms for novel otolaryngology‐related device testing. To achieve accurate representation of the anatomy, we utilized CT scans and 3D printing technology to create customized agar molds, thus providing high‐fidelity yet cost‐effective tools. Methods Based on previous studies, the key components in our neck phantom include the cervical vertebrae, trachea, common carotid arteries, internal jugular veins, thyroid gland, and surrounding soft tissue. Open‐source image analysis software were employed to process CT data to generate high fidelity 3D models of the target structures. Resin molds were 3D printed and filled with various agar mixtures to mimic anatomical echogenicity. Results Following the method proposed, we successfully assembled the neck phantom which provided a detailed representation of the target structures. To evaluate the results, ultrasound data was collected on the phantom and living tissue and analyzed with ImageJ. We were able to demonstrate echogenicity comparable to that of living tissue. Conclusion The proposed method for building neck phantoms with detailed anatomical features offers a valuable, detailed, low‐cost tool for medical training and device testing in otolaryngology, particularly for novel devices that involve artificial intelligence (AI) guidance and robotic‐based needle insertion. Additional anatomical refinements and validation studies could further enhance the consistency and accuracy, thus paving the way for future advancements in ultrasound training and research, and ultimately benefiting patient care and safety.

Introduction Determining aetiology of severe illness can be difficult, especially in settings with limited diagnostic resources, yet critical for providing life-saving care. Our objective was to describe the accuracy of antemortem clinical diagnoses in young children in high-mortality settings, compared with results of specific postmortem diagnoses obtained from Child Health and Mortality Prevention Surveillance (CHAMPS).Methods We analysed data collected during 2016–2022 from seven sites in Africa and South Asia. We compared antemortem clinical diagnoses from clinical records to a reference standard of postmortem diagnoses determined by expert panels at each site who reviewed the results of histopathological and microbiological testing of tissue, blood, and cerebrospinal fluid. We calculated test characteristics and 95% CIs of antemortem clinical diagnostic accuracy for the 10 most common causes of death. We classified diagnostic discrepancies as major and minor, per Goldman criteria later modified by Battle.Results CHAMPS enrolled 1454 deceased young children aged 1–59 months during the study period; 881 had available clinical records and were analysed. The median age at death was 11 months (IQR 4–21 months) and 47.3% (n=417) were female. We identified a clinicopathological discrepancy in 39.5% (n=348) of deaths; 82.3% of diagnostic errors were major. The sensitivity of clinician antemortem diagnosis ranged from 26% (95% CI 14.6% to 40.3%) for non-infectious respiratory diseases (eg, aspiration pneumonia, interstitial lung disease, etc) to 82.2% (95% CI 72.7% to 89.5%) for diarrhoeal diseases. Antemortem clinical diagnostic specificity ranged from 75.2% (95% CI 72.1% to 78.2%) for diarrhoeal diseases to 99.0% (95% CI 98.1% to 99.6%) for HIV.Conclusions Antemortem clinical diagnostic errors were common for young children who died in areas with high childhood mortality rates. To further reduce childhood mortality in resource-limited settings, there is an urgent need to improve antemortem diagnostic capability through advances in the availability of diagnostic testing and clinical skills.

The tomato, a genus of Lycopersicon, is cultivated worldwide for fruit. It is an important gastronomic ingredient and an important source of income for small farmers in Mali. However, its production faces a number of phytosanitary constraints that are still poorly understood. Among phytosanitary problems, bacterial wilt, caused by R. solanacearum, is proving to be the most dangerous and devastating of all tomato crops in Mali. The aim of this study is to contribute to the improvement of tomato production in Mali by identifying tomato varieties tolerant to R. solanacearum and adapted to the growing periods. To achieve this objective, trials under artificial and natural infestation conditions with 12 tomato genotypes during three periods were conducted at the Sotuba research station from December 2018 to December 2019. Analysis of variance revealed no significant difference between the two strains tested. Both strains were more severe, especially in period 2 of the experiment. The Caraïbo variety was the most susceptible to both strains, with an average severity rate of 2.8 (≈3) and the most stress-susceptibility index (0.69). The varieties Carioca and SF-83-61 were the most productive in both experimental conditions. With average yields ≥ 3.5 t/ha under artificial infestation conditions and ≥ 6 t/ha under natural conditions. In contrast, the Roma and Rossol varieties recorded the lowest yields. To minimize R. Solanacearum damage and improve field yields at all cropping periods, the SF-83-61 and Carioca varieties may be recommended for release in areas where R. Solanacearum, responsible for bacterial wilt, causes significant damage in tomato crops after confirmation tests.

La question de la légitimité des membres des assemblées citoyennes est un aspect peu étudié des exercices délibératifs et participatifs. Les membres des assemblées citoyennes, s’ils sont des acteurs clés des innovations institutionnelles, devraient disposer d’un statut juridique clairement défini afin de renforcer leur légitimité juridique. Si leur légitimité politique est forte, le vocable d’« assemblée citoyenne » contribue en partie à brouiller le cadre de leur légitimité. Une étude de la légitimité de celles-ci peut être nourrie par une analyse des deux dernières expériences françaises d’assemblée citoyenne que sont la Convention citoyenne pour le climat et la Convention citoyenne sur la fin de vie. L’utilisation du vocable d’« assemblée citoyenne » a un impact direct sur la légitimité des membres des exercices participatifs et contribue à en faire une fausse idée claire. La pérennisation des exercices délibératifs et participatifs au sein du système constitutionnel ne pourra s’opérer qu’au prix d’une clarification du statut des acteurs impliqués.

Adapting organic farming to climate change is a major issue. Cotton yields in Mali are declining due to deteriorating climatic conditions, soil fertility, and poor management. This study aimed to improve organic cotton yield in Mali in the future climate with the optimal choice of compost type, date, and dose of application. Experimental data collected in 2021 from the Sotuba research station in Mali was used for calibration and evaluation of the crop model DSSAT CSM-CROPGRO-Cotton model using phenology, leaf area index, and seed cotton yield. Climate data from the RCP4.5 and RCP8.5 scenarios of the GFDL-ESM2M model were used for future weather datasets for 2020-2039, 2040-2059, and 2060-2079. The model was able to simulate anthesis and maturity with excellent results, with nRMSE < 4%, and seed cotton yields moderately well, an nRMSE of 26% during calibration and 20.3% in evaluation. The scenario RCP8.5 from 2060 to 2079 gave the best seed cotton yields. Seed cotton yields with RCP4.5 and RCP8.5 were all better with the mid-May application period of small ruminant silo compost at 7.5 t/ha. In such conditions, more than 75% of the cases would produce more than 2000 kg/ha of seed cotton.

We present a financial history of the Seven Years’ War (1756–1763) using a new dataset derived from the Bank of England minutes. We argue that the war and the associated actions of the Bank of England led to a transformation of the financial system. Additionally, while there was short-term crowding out of private investment when interest rates rose due to the issue of war-related government debt, in the long-run there was crowding in: government spending led to an increase in private sector investment.

Primary age-related tauopathy (PART) is a neurodegenerative pathology with features distinct from but also overlapping with Alzheimer disease (AD). While both exhibit Alzheimer-type temporal lobe neurofibrillary degeneration alongside amnestic cognitive impairment, PART develops independently of amyloid-β (Aβ) plaques. The pathogenesis of PART is not known, but evidence suggests an association with genes that promote tau pathology and others that protect from Aβ toxicity. Here, we performed a genetic association study in an autopsy cohort of individuals with PART (n = 647) using Braak neurofibrillary tangle stage as a quantitative trait. We found some significant associations with candidate loci associated with AD (SLC24A4, MS4A6A, HS3ST1) and progressive supranuclear palsy (MAPT and EIF2AK3). Genome-wide association analysis revealed a novel significant association with a single nucleotide polymorphism on chromosome 4 (rs56405341) in a locus containing three genes, including JADE1 which was significantly upregulated in tangle-bearing neurons by single-soma RNA-seq. Immunohistochemical studies using antisera targeting JADE1 protein revealed localization within tau aggregates in autopsy brains with four microtubule-binding domain repeats (4R) isoforms and mixed 3R/4R, but not with 3R exclusively. Co-immunoprecipitation in post-mortem human PART brain tissue revealed a specific binding of JADE1 protein to four repeat tau lacking N-terminal inserts (0N4R). Finally, knockdown of the Drosophila JADE1 homolog rhinoceros (rno) enhanced tau-induced toxicity and apoptosis in vivo in a humanized 0N4R mutant tau knock-in model, as quantified by rough eye phenotype and terminal deoxynucleotidyl transferase dUTP nick end-labeling (TUNEL) in the fly brain. Together, these findings indicate that PART has a genetic architecture that partially overlaps with AD and other tauopathies and suggests a novel role for JADE1 as a modifier of neurofibrillary degeneration.

AbstractPrimary age-related tauopathy (PART) is a neurodegenerative tauopathy with features distinct from but also overlapping with Alzheimer disease (AD). While both exhibit Alzheimer-type temporal lobe neurofibrillary degeneration alongside amnestic cognitive impairment, PART develops independently of amyloid-β (Aβ) deposition in plaques. The pathogenesis of PART is unknown, but evidence suggests it is associated with genes that promote tau pathology as well as others that protect from Aβ toxicity. Here, we performed a genetic association study in an autopsy cohort of individuals with PART (n=647) using Braak neurofibrillary tangle stage as a quantitative trait adjusting for sex, age, genotyping platform, and principal components. We found significant associations with some candidate loci associated with AD and progressive supranuclear palsy, a primary tauopathy (SLC24A4, MS4A6A, HS3ST1, MAPT and EIF2AK3). Genome-wide association analysis revealed a novel significant association with a single nucleotide polymorphism on chromosome 4 (rs56405341) in a locus containing three genes, including JADE1 which was significantly upregulated in tangle-bearing neurons by single-soma RNA-seq. Immunohistochemical studies using antisera targeting JADE1 protein revealed localization within tau aggregates in autopsy brain from tauopathies containing isoforms with four microtubule-binding domain repeats (4R) and mixed 3R/4R, but not with 3R exclusively. Co-immunoprecipitation revealed a direct and specific binding of JADE1 protein to tau containing four (4R) and no N-terminal inserts (0N4R) in post-mortem human PART brain tissue. Finally, knockdown of the Drosophila JADE1 homolog rhinoceros (rno) enhanced tau-induced toxicity and apoptosis in vivo in a humanized 0N4R mutant tau knock-in model as quantified by rough eye phenotype and terminal deoxynucleotidyl transferase dUTP nick end-labeling (TUNEL) in the fly brain. Together, these findings indicate that PART has a genetic architecture that partially overlaps with AD and other tauopathies and suggests a novel role for JADE1 as a mediator of neurofibrillary degeneration.

Authors propose their splenic mimetic filtration method, microsphiltration, and utilise this approach in a drug-screen, to identify compounds that induce a stiffening effect on Plasmodium falciparum-infected erythrocytes. They proceed to assess safety and tolerability of one identified compound in a phase I clinical trial.

Background: Epilepsy is a significant public health concern with psychosocial impacts, including fear, stigma, and misconceptions. These factors contribute to human rights violations and discrimination. The objective of this study was to describe the sociocultural representation of epilepsy in Mali. Materials and methods: This cross-sectional descriptive study was carried out from April 2015 to November 2016 at the University Hospital of Point G. Patients with epilepsy were identified prospectively, and a questionnaire was administered to each patient and their parents. Results: A total of 104 patients were enrolled with an average age of 35 years, ranging from 15 to 89 years. Males were slightly predominant, accounting for 53.85%, resulting in a sex ratio (M/F) of 1.17. In terms of occupation, workers comprised 68.27% of participants. Patients residing in urban areas represented 61.54%, and the most level of education was secondary (40.38%). The majority of patients (57.69%) and their relatives (69.23%) thought that epilepsy was caused by mystical causes. Stigma was reported by 66.35% of our patients. Conclusion: The sociocultural perception of epilepsy hinders evidence-based diagnosis and management in Africa. This study suggests a need to focus on raising awareness to change these misconceptions.

Introduction Malaria, a devastating febrile illness caused by protozoan parasites, sickened 247,000,000 people in 2021 and killed 619,000, mostly children and pregnant women in sub-Saharan Africa. A highly effective vaccine is urgently needed, especially for Plasmodium falciparum (Pf), the deadliest human malaria parasite. Areas covered Sporozoites (SPZ), the parasite stage transmitted by Anopheles mosquitoes to humans, are the only vaccine immunogen achieving > 90% efficacy against Pf infection. This review describes > 30 clinical trials of PfSPZ vaccines in the U.S.A., Europe, Africa, and Asia, based on first-hand knowledge of the trials and PubMed searches of ‘sporozoites,’ ‘malaria,’ and ‘vaccines.’ Expert opinion First generation (radiation-attenuated) PfSPZ vaccines are safe, well tolerated, 80-100% efficacious against homologous controlled human malaria infection (CHMI) and provide 18-19 months protection without boosting in Africa. Second generation chemo-attenuated PfSPZ are more potent, 100% efficacious against stringent heterologous (variant strain) CHMI, but require a co-administered drug, raising safety concerns. Third generation, late liver stage-arresting, replication competent (LARC), genetically-attenuated PfSPZ are expected to be both safe and highly efficacious. Overall, PfSPZ vaccines meet safety, tolerability, and efficacy requirements for protecting pregnant women and travelers, with licensure for these populations possible within five years. Protecting children and mass vaccination programs to block transmission and eliminate malaria are long-term objectives.

Summary: Background: Most childhood deaths globally are considered preventable through high-quality clinical care, which includes adherence to clinical care recommendations. Our objective was to describe adherence to World Health Organization recommendations for the management of leading causes of death among children. Methods: We conducted a retrospective, descriptive study examining clinical data for children aged 1–59 months who were hospitalized and died in a Child Health and Mortality Prevention Surveillance (CHAMPS) catchment, December 2016–June 2021. Catchment areas included: Baliakandi and Faridpur, Bangladesh; Kersa, Haramaya, and Harar, Ethiopia; Kisumu and Siaya, Kenya; Bamako, Mali; Manhiça and Quelimane, Mozambique; Makeni, Sierra Leone; Soweto, South Africa. We reviewed medical records of those who died from lower respiratory tract infections, sepsis, malnutrition, malaria, and diarrheal diseases to determine the proportion who received recommended treatments and compared adherence by hospitalization duration. Findings: CHAMPS enrolled 460 hospitalized children who died from the leading causes (median age 12 months, 53.0% male). Median hospital admission was 31 h. There were 51.0% (n = 127/249) of children who died from lower respiratory tract infections received supplemental oxygen. Administration of intravenous fluids for sepsis (15.9%, n = 36/226) and supplemental feeds for malnutrition (14.0%, n = 18/129) were uncommon. There were 51.4% (n = 55/107) of those who died from malaria received antimalarials. Of the 80 children who died from diarrheal diseases, 76.2% received intravenous fluids. Those admitted for ≥24 h more commonly received antibiotics for lower respiratory tract infections and sepsis, supplemental feeds for malnutrition, and intravenous fluids for sepsis than those admitted

Methylenetetrahydrofolate reductase (MTHFR) plays a major role in the metabolism of folates and homocysteine, which in turn can affect gene expression and ultimately promote the development of breast cancer. Thus, mutations in the MTHFR gene could influence homocysteine, methionine, and S-adenosylmethionine levels and, indirectly, nucleotide levels. Imbalance in methionine and S-adenosylmethionine synthesis affects protein synthesis and methylation. These changes, which affect gene expression, may ultimately promote the development of breast cancer. We therefore hypothesized that such mutations could also play an important role in the occurrence and pathogenesis of breast cancer in a Malian population. In this study, we used the PCR-RFLP technique to identify the different genotypic profiles of the C677T MTHFR polymorphism in 127 breast cancer women and 160 healthy controls. The genotypic distribution of the C677T polymorphism in breast cancer cases was 88.2% for CC, 11.0% for CT, and 0.8% for TT. Healthy controls showed a similar distribution with 90.6% for CC, 8.8% for CT, and 0.6% for TT. We found no statistical association between the C677T polymorphism and breast cancer risk for the codominant models CT and TT p>0.05. The same trend was observed when the analysis was extended to other genetic models, including dominant (p = 0.50), recessive (p = 0.87), and additive (p = 0.50) models. The C677T polymorphism of MTHFR gene did not influence the risk of breast cancer in the Malian samples.
