RESUMO
INTRODUCTION: Leprosy and lymphatic filariasis (LF) are among the most disabling neglected tropical diseases (NTDs) that affect the citizens of Mozambique, especially in the Northern provinces. The irreversible impairments caused by these NTDs often lead to psychosocial consequences, including poor mental wellbeing, stigma and reduced social participation. Limited data on these consequences are available for Mozambique, which are urgently needed to better understand the true disease burden and support advocacy for scaling up interventions. METHODS: A cross-sectional mixed-methods study was conducted. Mental distress was assessed with the Self Reporting Questionnaire (SRQ-20), participation restriction was assessed with the Participation Scale Short (PSS) and perceived stigma was assessed with the Explanatory Model Interview Catalogue affected persons stigma scale (EMIC-AP). Additionally, semi-structured interviews were conducted with persons affected by leprosy or LF. RESULTS: In total, 127 persons affected by leprosy and 184 persons affected by LF were included in the quantitative portion of the study. For the qualitative portion, eight semi-structured interviews were conducted. In both disease groups, mental distress was found in 70% of participants. Moreover, 80% of persons affected by leprosy and 90% of persons affected by LF perceived stigma. Moderate to extreme participation restriction was found in approximately 43% of persons affected by leprosy and in 26% of the persons affected by LF. Persons affected by leprosy and LF felt excluded from society and experienced financial problems. More severe disabilities were associated with more severe outcomes for mental wellbeing, participation restriction and stigma. By contrast, participation in a self-care group was suggested to have a positive impact on these outcomes. CONCLUSION: The findings provide evidence that persons affected by leprosy and LF must not only confront physical impairments but also experience significant disability in the psychosocial domain, including mental distress, participation restriction and stigma. These challenges must be urgently addressed by NTD programmes to promote the inclusion and wellbeing of persons affected by NTDs.

Mycetoma profoundly affects marginalised communities, especially in impoverished and remote areas with limited access to healthcare. This chronic and debilitating inflammatory disease highlights the typical issues of neglected tropical diseases (NTDs), such as insufficient attention, funding, and resources, which perpetuate neglect and suffering. Patients often delay seeking medical help, leading to advanced disease stages, severe complications, and lasting disabilities. The lack of medical infrastructure and skilled healthcare professionals worsens the situation, causing delays in diagnosis and inadequate treatment. Engaging affected communities in tailored interventions is essential to tackle these challenges, promote collaboration, raise awareness, and mobilise resources to improve healthcare access and enhance diagnostic and treatment capabilities. Since 1991, the Mycetoma Research Center (MRC) at the University of Khartoum, Sudan, has led community engagement initiatives aimed at improving the quality of life for mycetoma-affected individuals through education, advocacy, and local collaboration. In this communication, the MRC shares its extensive experience in community engagement to benefit mycetoma-affected communities.

BACKGROUND: Neglected Tropical Diseases (NTDs) disproportionately affect marginalised groups within impoverished communities, conferring devastating physical, financial and psychosocial effects. Skin-NTDs (SNTDs) are uniquely stigmatising due to their visible nature, rendering affected individuals vulnerable to psychosocial risk and the associated decline in social participation, quality of life and mental health. In response to knowledge gaps identified by current global efforts for integrated control of SNTDs this review gathers existing evidence on the psychosocial effects of SNTDs, with consideration given to the influence of gender. METHODS: The study protocol is registered with PROSPERO (CRD42022336676). Data was collected from Embase, Global Health, Medline and Web of Science, with additional articles identified through Google Scholar and bibliography tracking. Qualitative studies published in English between 2005 and 2024 reporting men's and women's experiences with SNTDs were searched. Appropriate data from each included study were inputted into NVivo software to facilitate thematic synthesis. Descriptive and analytic themes were generated through line-by-line coding using an inductive approach. RESULTS: 27 articles of high and moderate quality were included. They pertained to buruli ulcer, cutaneous leishmaniasis, leprosy, lymphatic filariasis, tungiasis, onchocerciasis, schistosomiasis and podoconiosis. Men and women across SNTDs and contexts reported debilitating physical symptoms which impaired their ability to work, socialise and carry out usual daily activities. Some felt (at least initially) well supported by partners and relatives, whereas most experienced avoidance, abandonment and even violence, with women incurring worse SNTD-related social consequences. Many men and most women experienced stigma, with discriminatory behaviours largely attributed to fear of infection, decreased ability to perform gender-specific daily activities, and the perceived association between SNTDs and sinfulness. Self-reported impacts of SNTDs on men's and women's mental wellbeing included low mood, anxiety, low self-esteem, and suicidal ideation. Disease-specific knowledge, early treatment, social support, and disease acceptance were mentioned as protective factors. CONCLUSION: SNTDs cause significant psychosocial harms, particularly for women. Implementing myth-busting and contact-based educational campaigns and improving access to treatment and to livelihood opportunities and social protection schemes for men and women with a SNTD will help prevent and mitigate these.

Human schistosomiasis is a parasitic disease caused by an infection with trematodes of the genus Schistosoma. The disease mainly affects impoverished populations. Around 800 million people are exposed to the infection, which is a public health problem in the tropical and subtropical regions of Africa, Asia, the Caribbean and South America. In Brazil, Schistosoma mansoni is the only species that causes schistosomiasis and the disease is widely distributed. Conventional diagnosis of the disease is carried out by detecting eggs using parasitological methods, such as the Kato-Katz test. Schistosomiasis has been reported in all regions of Brazil and is characterized as endemic in seven states in the Northeast Region and two states in the Southeast Region. In 2015, 78,7% of all cases reported in Brazil occurred in the Northeast Region. It is estimated that 1,5 million people is infected with this disease in Brazil and more than 25 millions live in areas with a high risk of transmission. Despite the reduction in mortality and morbidity, schistosomiasis was responsible for 8,756 deaths between 2000 and 2011 and 2,517 deaths between 2015 and 2019 in Brazil and it remains an important public health problem. In the state of Rio de Janeiro, some areas have low endemicity or isolated foci of Schistosoma mansoni and the majority of infected individuals have mild infections. The last survey of the disease in the state of Rio de Janeiro was carried out between 2010 and 2015 in students aged 7 to 17.Schistosomiasis was reported in 10 of the 21 municipalities studied. Of the 5,111 school children screened for S. mansoni infection, 46 (1,65%) were tested positive. Studies carried out in areas of low endemicity in Rio de Janeiro showed that among the 205 patients infected by S. mansoni in Sumidouro, around 84% were aged 14 or over and all, except one individual, had the intestinal form (91,2%) or hepato-intestinal (8,3%) of schistosomiasis. Another study carried out in Sumidouro showed that with tests based on patent Schistosoma egg infection determined by the Kato-Katz test, active infections were diagnosed in eight (8/108) individuals. The intensity of infection expressed by parasite loads ranged from 6 to 72 eggs per gram of feces/individual. The results showed DNA amplification in 32 of the 100 individuals tested by real-time PCR. All individuals with patent ovo infection showed positive DNA amplification. These studies showed that if we only analyzed school-age children using the Kato-Katz test, the majority of the infected population would never be diagnosed with S. mansoni infection. In situations of low endemicity, with low intensities of infection, with low severity in the population and in the most affected age groups, schistosomiasis requires a more sensitive diagnostic approach (e.g. screening by PCR rather than Kato test), otherwise many infected individuals will remain invisible to the healthcare system.
A esquistossomose humana é uma doença parasitária causada por uma infecçâo por vermes sanguíneos do gènero Schistosoma. A doença afeta principalmente populaçoes empobrecidas. Cerca de 800 milhoes de pessoas estâo expostas à infecçâo, sendo um problema de saúde pública nas regioes tropicais e subtropicais de África, Ásia, Caribe e América do Sul. No Brasil, o Schistosoma mansoni é a única espécie causadora da esquistossomose e a doença é amplamente distribuida. O diagnóstico convencional da doença é realizado pela detecçâo dos ovos através de métodos parasitológicos, como o teste de Kato-Katz. A esquistossomose foi notificada em todas as regioes do Brasil, e é caracterizada como endèmica em sete estados da Regiâo Nordeste e dois estados da Regiâo Sudeste. Em 2015, 78,7% de todos os casos notificados no Brasil ocorreram na Regiâo Nordeste. Estima-se que 1,5 milhâo de pessoas estejam infectadas com esta doença no Brasil e mais de 25 milhoes vivam em áreas com alto risco de transmissâo. Apesar da reduçâo da mortalidade e morbidade, a esquistossomose foi relatada em 8.756 mortes entre 2000 e 2011 e em 2.517 mortes entre 2015 e 2019 no Brasil e continua sendo um importante problema de saúde pública. No Estado do Rio de Janeiro, algumas áreas apresentam baixa endemicidade ou focos isolados de Schistosoma mansoni e a maioria dos individuos infectados apresenta infecçoes leves. O último levantamento da doença no Estado do Rio de Janeiro foi realizado entre 2010 e 2015 em estudantes de 7 a 17 anos. A esquistossomose foi relatada em 10 dos 21 municipios estudados. Das 5.111 crianças escolares triadas para infecçâo por S. mansoni, 46 (1,65%) testaram positivo. Estudos realizados em áreas de baixa endemicidade no Rio de Janeiro mostraram que dentre os 205 pacientes infectados por S. mansoni em Sumidouro, cerca de 84% tinham 14 anos ou mais e todos, exceto um individuo, tinham a forma intestinal (91,2%) ou hepato-intestinal (8,3%) da esquistossomose. Outro estudo realizado em Sumidouro, mostrou que testes baseados em infecçâo patente de ovo de Schistosoma determinada pelo teste de Kato-Katz, infecçoes ativas foram diagnosticadas em oito (8/108) individuos. A intensidade de infecçâo expressa pelas cargas parasitárias variou de 6 a 72 ovos por grama de fezes/individuo. Os resultados mostraram amplificaçâo do DNA em 32 dos 100 individuos testados por PCR em tempo real. Todos os indivíduos com infecçâo ovo-patente apresentaram amplificaçâo de DNA positiva. Tais estudos mostraram que se analisarmos apenas crianças em idade escolar pelo teste de Kato-Katz, a maioria da populaçâo infectada nunca seria diagnosticada com infecçâo pelo S. mansoni. Em situaçoes de baixa endemicidade, com baixas intensidades de infecçâo, com baixa gravidade na populaçâo e nas faixas etárias mais afetadas, a esquistossomose requer uma abordagem diagnóstica mais sensivel (por exemplo, triagem por PCR em vez do teste de Kato), caso contràrio, muitos individuos infectados permanecerâo invisiveis para o sistema de saúde.

Neglected tropical diseases (NTDs) pose a major threat in tropical zones for impoverished populations. Difficulty of access, adverse effects or low efficacy limit the use of current therapeutic options. Therefore, development of new drugs against NTDs is a necessity. Compounds containing an aminopyridine (AP) moiety are of great interest for the design of new anti-NTD drugs due to their intrinsic properties compared with their closest chemical structures. Currently, over 40 compounds with an AP moiety are on the market, but none is used against NTDs despite active research on APs. The aim of this review is to present the medicinal chemistry work carried out with these scaffolds, against protozoan NTDs: Trypanosoma cruzi, Trypanosoma brucei or Leishmania spp.

Chagas disease (CD) is recognized as one of the 20 neglected tropical diseases by the World Health Organization (WHO), posing a significant global health challenge. The objective of this work was to conduct a systematic methodology review to explore the different classifications used to describe the presence and degree of organ involvement in patients with CD since the disease's description in 1909. We searched relevant electronic medical databases from their inception dates to July 2023. We also delved into historical variations and revisions of each classification, the necessary diagnostic methods, their prognostic value, and their uptake. Our study underscores the conspicuous absence of a universally accepted CD classification system for cardiac and digestive involvement, both in the context of clinical trials and within current clinical guidelines. This endeavour will facilitate cross-population comparisons if clinical manifestations and complementary test results are available for each patient, constituting a pivotal stride toward identifying precise prognoses and establishing a minimum data set requisite for a fitting CD classification, tailored to the test availability in both endemic and non-endemic regions.

BACKGROUND: In recent years, the escalating concern for neglected tropical diseases (NTDs) has been recognized as a pressing global health issue. This concern is acutely manifested in low- and middle-income countries, where there is an escalating prevalence among adolescents and young adults. The burgeoning of these conditions threatens to impair patients' occupational capabilities and overall life quality. Despite the considerable global impact of NTDs, comprehensive studies focusing on their impact in younger populations remain scarce. Our study aims to describe the global prevalence of neglected tropical diseases among people aged 15 to 39 years over the 30-year period from 1990 to 2019, and to project the disease burden of the disease up to 2040. METHODS: Annual data on incident cases, mortality, and disability-adjusted life years (DALYs) for NTDs were procured from the Global Burden of Disease Study 2019 (GBD 2019). These data were stratified by global and regional distribution, country, social development index (SDI), age, and sex. We computed age-standardized rates (ASRs) and the numbers of incident cases, mortalities, and DALYs from 1990 to 2019. The estimated annual percentage change (EAPC) in the ASRs was calculated to evaluate evolving trends. RESULTS: In 2019, it was estimated that there were approximately 552 million NTD cases globally (95% Uncertainty Interval [UI]: 519.9 million to 586.3 million), a 29% decrease since 1990. South Asia reported the highest NTD prevalence, with an estimated 171.7 million cases (95% UI: 150.4 million to 198.6 million). Among the five SDI categories, the prevalence of NTDs was highest in the moderate and low SDI regions in 1990 (approximately 270.5 million cases) and 2019 (approximately 176.5 million cases). Sub-Saharan Africa recorded the most significant decline in NTD cases over the past three decades. Overall, there was a significant inverse correlation between the disease burden of NTDs and SDI. CONCLUSION: NTDs imposed over half a billion incident cases and 10.8 million DALYs lost globally in 2019-exerting an immense toll rivaling major infectious and non-communicable diseases. Encouraging declines in prevalence and disability burdens over the past three decades spotlight the potential to accelerate progress through evidence-based allocation of resources. Such strategic integration could substantially enhance public awareness about risk factors and available treatment options.

Se trata una niña de siete años de edad, originaria de una zona rural del departamento de San Miguel, quién consultó por presentar fiebre y edema bipalpebral derecho indoloro, de seis semanas de evolución, sin otros síntomas acompañantes. El estudio para el diagnóstico de enfermedad de Chagas fue realizado en una clínica privada; la Inmunoglobulina M para Chagas tuvo un resultado positivo, luego, se realizó la microscopía directa mediante gota al fresco y técnica de Strout con resultado negativo. En las intervenciones comunitarias se identificó la presencia del vector y la positividad del mismo, así como el diagnóstico de un caso crónico en otro miembro de la familia. Intervención terapéutica. Se indicó tratamiento con nifurtimox 150 mg cada ocho horas por 60 días y se realizó el seguimiento clínico de la evolución y control de efectos secundarios del tratamiento y exámenes de laboratorio. Evolución clínica. Evolucionó con leve disminución del apetito, se manejó con protectores gástricos. El concentrado de Strout y la gota al fresco resultaron negativos y los demás exámenes de laboratorio se mantenían en los rangos normales.
Case presentation. A seven-year-old female patient, with no previous medical history, originally from a rural area of the department of San Miguel, who presented febrile process plus long-term right bipalpebral edema of six weeks of evolution, without accompanying symptoms. Immunoglobulin M for Chagas was positive, direct microscopy by fresh drop and Strout technique was performed with negative results. In community interventions, the presence of the vector and its positivity were identified, as well as the diagnosis of a chronic case in another family member. Treatment. The patient was treated with nifurtimox 150 mg every eight hours for 60 days, subsequent controls were performed to investigate side effects of the treatment, and control tests. Outcome. With the treatment, the patient evolved with a slight decrease in appetite, and was managed with gastric protectors. Strout's concentrate and fresh gout were negative and the other laboratory tests were within normal ranges.

Presentación del caso. Se trata de una mujer de 45 años con úlcera en el muslo izquierdo, con forma ovalada, bordes bien definidos y elevados, sin secreción, sin costra, e indolora, que presentó una lesión de 60 días de evolución, que inició como una pápula puntiforme de aumento progresivo en tamaño y profundidad hasta generar una úlcera, después de cuatro semanas de haber realizado un viaje de tres días a un área rural endémica para leishmaniasis tegumentaria americana. Intervención terapéutica. Se confirmó el diagnóstico de leishmaniasis cutánea localizada, en consecuencia, recibió tratamiento ambulatorio con miltefosina de 50 mg por vía oral cada ocho horas por un total de 28 días, acompañado de seguimiento clínico y de laboratorio. Evolución clínica. Se presentaron efectos secundarios leves, entre ellos, las náuseas que cedieron con el tratamiento con ondansetrón y omeprazol, luego presentó hiporexia, que persistió hasta el final del tratamiento. No hubo alteraciones laboratoriales significativas. La paciente fue evaluada periódicamente según las recomendaciones del Ministerio de Salud de Brasil y se observó una mejoría clínica gradual de la lesión, hasta que en la evaluación del día noventa fue determinada la cura clínica.
Case presentation. The patient is a 45-year-old woman with an oval-shaped ulcer on the left thigh, with well-defined and raised borders, no discharge, no crust, and painless; she presented a lesion of 60 days of evolution, which started as a punctate papule of progressive increase in size and depth until it became an ulcer, four weeks after a three-day trip to a rural area endemic for American tegumentary leishmaniasis. Treatment. The diagnosis of localized cutaneous leishmaniasis was confirmed; consequently, the patient received outpatient treatment with miltefosine 50 mg orally every eight hours for 28 days, accompanied by clinical and laboratory follow-up. Clinical outcome. There were mild side effects, including nausea that subsided with treatment with ondansetron and omeprazole, and later hyporexia, which persisted until the end of treatment. There were no significant laboratory alterations. The patient was periodically evaluated according to the recommendations of the Brazilian Ministry of Health, and the lesion improved gradually, reaching a clinical cure on the 90th day.

Tracers of health system equity, neglected tropical diseases (NTDs) disproportionately affect marginalized populations. NTDs that manifest on the skin - "skin NTDs" - are associated with scarring, disfigurement, physical disability, social exclusion, psychological distress, and economic hardship. To support development and evaluation of appropriate intervention strategies, we aimed to improve understanding of the role of economic factors in shaping and constituting the burden that skin NTDs place on households. We collected data in 2021 in two predominantly rural districts: Atwima Mponua in Ghana (where Buruli ulcer, yaws, and leprosy are endemic) and Kalu in Ethiopia (where cutaneous leishmaniasis and leprosy are endemic). We conducted interviews (n = 50) and focus group discussions (n = 14) that explored economic themes with affected individuals, caregivers, and community members and analysed the data thematically using a pre-defined framework. We found remarkable commonalities across countries and diseases. We developed a conceptual framework which illustrates skin NTDs' negative economic impact, including financial costs of care-seeking and reductions in work and schooling; categorises coping strategies by their degree of risk-pooling; and clarifies the mechanisms through which skin NTDs disproportionately affect the poorest. Despite health insurance schemes in both countries, wide-ranging, often harmful coping strategies were reported. Traditional healers were often described as more accessible, affordable and offering more flexible payment terms than formal health services, except for Ethiopia's well-established leprosy programme. Our findings are important in informing strategies to mitigate the skin NTD burden and identifying key drivers of household costs to measure in future evaluations. To reduce skin NTDs' impact on households' physical, mental, and economic wellbeing, intervention strategies should address economic constraints to prompt and effective care-seeking. While financial support and incentives for referrals and promotion of insurance enrolment may mitigate some constraints, structural interventions that decentralise care may offer more equitable and sustainable access to skin NTD care.

Immunosuppressed patients, particularly transplant recipients, can develop severe strongyloidiasis. This study aimed to detect anti-Strongyloides IgG antibodies in a panel of sera from liver transplant patients. Two techniques were used: ELISA as the initial screening test and Western blotting as a confirmatory test. ELISA reactivity of 10.9% (32/294) was observed. The 40-30 kDa fraction was recognised in 93.7% (30/32) of the patients, resulting in a positivity rate of 10.2%. These data highlight the importance of serological screening for Strongyloides stercoralis infection in liver transplant recipients.

BACKGROUND: The burden of neglected tropical diseases (NTDs), HIV/AIDS, tuberculosis, and malaria pose significant public health challenges in Ethiopia. This study aimed to the explore service availability and readiness for NTD care among Ethiopian health facilities treating tuberculosis (TB), HIV/AIDS, and/or malaria. METHODS: This study utilized secondary data from the Ethiopian Service Provision Assessment 2021-22 survey. The availability of services was calculated as the percentage of HIV/AIDS, tuberculosis, or malaria facilities providing NTD services. Facilities were considered highly prepared to manage any type of NTD if they scored at least half (> 50%) of the tracer items listed in each of the three domains (staff training and guidelines, equipment, and essential medicines). Descriptive statistics and logistic regression models were employed to present the study findings and analyze factors influencing facility readiness, respectively. RESULTS: Out of 403 health facilities providing NTD care nationally, 179, 183, and 197 also offer TB, HIV/AIDS, and malaria services, respectively. The majority of TB (90.1%), HIV/AIDS (89.6%), and malaria (90.9%) facilities offer soil-transmitted helminth services, followed by trachoma (range 87-90%). The percentages of the aforementioned facilities with at least one trained staff member for any type of NTD were 87.2%, 88.4%, and 82.1%, respectively. The percentage of facilities with guidelines for any type of NTD was relatively low (range 3.7-4.1%). Mebendazole was the most widely available essential medicine, ranging from 69 to 70%. The overall readiness analysis indicated that none of the included facilities (TB = 11.9%; HIV/AIDS = 11.6%; and malaria = 10.6%) were ready to offer NTD care. Specifically, a higher level of readiness was observed only in the domain of medicines across these facilities. Hospitals had better readiness to offer NTD care than did health centers and clinics. Furthermore, a significant associations were observed between facility readiness and factors such as facility type, region, presence of routine management meetings, types of NTD services provided, and fixed costs for services. CONCLUSIONS: Ethiopian health facilities treating TB, HIV/AIDS, and malaria had an unsatisfactory overall service availability and a lack of readiness to provide NTD care. Given the existing epidemiological risks and high burden of TB, HIV/AIDS, malaria, and NTDs in Ethiopia, there is an urgent need to consider preparing and implementing a collaborative infectious disease care plan to integrate NTD services in these facilities.

OVERVIEW: The roadmap adopted by the World Health Organization (WHO) for eliminating neglected tropical diseases aims to eliminate schistosomiasis, as a public health concern, by 2030. While progress has been made towards reducing schistosomiasis morbidity control in several sub-Saharan African countries, there is still more that needs to be done. Proper surveillance using accurate diagnostics with acceptable sensitivity and specificity is essential for evaluating the success of all efforts against schistosomiasis. Microscopy, despite its low sensitivity, remains the gold standard approach for diagnosing the disease. Although many efforts have been made to develop new diagnostics based on circulating parasite proteins, genetic markers, schistosome egg morphology, and their paramagnetic properties, none has been robust enough to replace microscopy. This review highlights common diagnostic approaches for detecting schistosomiasis in field and clinical settings, major challenges, and provides new and novel opportunities and diagnosis pathways that will be critical in supporting elimination of schistosomiasis. METHODS: We searched for relevant and reliable published literature from PubMed, Scopus, google scholar, and Web of science. The search strategies were primarily determined by subtopic, and hence the following words were used (schistosom*, diagnosis, Kato-Katz, antibody test, circulating antigen, POC-CCA, UCP-LF-CAA, molecular diagnostics, nucleic acid amplification test, microfluidics, lab-on a disk, lab-on chip, recombinase polymerase amplification (RPA), LAMP, portable sequencer, nanobody test, identical multi-repeat sequences, diagnostic TPPs, REASSURED, extraction free), and Boolean operators AND and/OR were used to refine the searching capacity. Due to the global public health nature of schistosomiasis, we also searched for reliable documents, reports, and research papers published by international health organizations, World Health Organization (WHO), and Center for Disease control and Elimination.

Rocky Mountain spotted fever (RMSF), a severe and extraordinarily lethal infectious disease, has emerged as a widespread public health crisis among predominantly vulnerable populations in several countries of Latin America, particularly evident in northern Mexico. Historically, RMSF has gained less attention than many other tropical infectious diseases, resulting in insufficient allocations of resources and development of capabilities for its prevention and control in endemic regions. We argue that RMSF fulfills accepted criteria for a neglected tropical disease (NTD). The relative neglect of RMSF in most Latin American countries contributes to disparities in morbidity and mortality witnessed in this region. By recognizing RMSF as an NTD, an increased public policy interest, equitable and more appropriate allocation of resources, scientific interest, and social participation can ameliorate the impact of this potentially treatable disease, particularly in vulnerable populations.

INTRODUCTION: The leishmaniases are among the group of neglected tropical diseases that cause significant morbidity and mortality each year. Currently, the East Africa region has the highest visceral leishmaniasis burden in the world. Ethiopia is one of the East African countries that reports both visceral and cutaneous forms of the disease. As part of the Nairobi Declaration, Ethiopia showed commitment to the elimination of visceral leishmaniasis by 2030. In this endeavour, it is important to understand the scope of research conducted on leishmaniases in the country and identify where the research gaps exist. Determining the research landscape is vital in the plan towards leishmaniases control and elimination. It will help to reference conducted research, determine if systematic reviews are warranted and help prioritise future research directions. METHODS AND ANALYSIS: This protocol was developed with reference to the JBI Scoping Review Methodology Group's guidance on conducting scoping reviews and the PRISMA-ScR reporting guidelines for scoping reviews. The following databases will be searched: PubMed, Embase via Embase.com, Web of Science Core Collection, Cochrane CENTRAL, Global Index Medicus, ClinicalTrials.gov, the Pan African Clinical Trials Registry and PROSPERO. Locally published literature that may not be indexed in the above-mentioned systems will be identified through team members familiar with the setting. Each record will be dually and blindly reviewed in an abstract-title screen and full-text screen using inclusion-exclusion criteria. Included articles must contain an in-depth discussion of leishmaniasis in Ethiopia. Data extracted will consist of study themes, study types, and categories and subcategories each defined in the developed codebook, in addition to type of leishmania, year of publication, funding source and the number of citations. Results will be reported with summary statistics. ETHICS AND DISSEMINATION: Individual consenting and ethical approvals are not applicable. We plan to disseminate our findings to the appropriate stakeholders.

BACKGROUND: This study investigates the impact of the COVID-19 pandemic on the prevalence, management, and control of the neglected tropical diseases (NTDs) highlighting the current or prospective impact of COVID-19 on research and development funding for, and execution of, NTD programmes. This review was conducted to determine if, and how, NTDs were affected by COVID-19, and whether those effects will delay the elimination goals of the Sustainable Development goals. METHODS: Using open-source available data from policy and documentation from official websites of the relevant stakeholders including but not limited to World Health Organization (WHO) documents and policies, government foreign aid documents, and the Policy Cures G-Finder reports, this scoping review explored ongoing challenges to supporting research and development (R&D) for the NTDs and in maintaining NTD control programs; examined the constraints posed for NTD management by the pandemic from disruptions to healthcare services, reduction of finance and explored the potential long-term implications and consequences for those poorer, neglected populations in low and middle income-countries (LMICs). This was done by a scoping review literature search, publications were subject to an initial practical screening step to ensure the most relevant publications were selected for full screening, with the focus on scoping the designated topic of the impact of COVID-19 on NTDs. We further undertook an evaluation of the socio-economic factors exacerbating the impact of COVID-19 on NTD burden. RESULTS: Multiple disruptions and setbacks, likely to affect NTD programmes and progress towards their elimination targets were identified in this study. R&D funding for the NTDs and AIDs and TB has declined since the funding high point of 2019, and for malaria since the high point of 2018. Significant changes in allocation of R&D funding within the NTDs are observed post pandemic, likely because of prioritization among donors. Diseases for which the least R&D investment was reported in place, prior to the pandemic (mycetoma, taeniasis/cysticercosis, trachoma and Buruli ulcer) have been particularly impacted post pandemic. We identified specific NTDs including schistosomiasis, leprosy, and rabies that have been affected by the COVID-19 pandemic and disruptions caused to on ongoing NTD control and elimination programs. Pandemic restrictions disrupted essential medical supply manufacturing and distribution impacting immunization programs and hindered efforts to control the spread of infectious diseases. NTD programmes have experienced numerous setbacks including delays in mass drug administration programs (e.g. for schistosomiasis), cancelled or delayed vaccination programs (e.g. for rabies) and closure of testing facilities has resulted in reduced diagnosis, treatment, and disease elimination for all NTDs. Lockdowns and clinic closures causing disruption to essential healthcare services restricted NTD surveillance and treatment programs. Community fears around contracting COVID-19 exacerbated the constraints to service delivery. Disparities in global vaccine distribution have widened with LMICs facing limited access to vaccines and disruption to immunization programs. Finally, the pandemic has led to increased poverty with poor and marginalized communities, impacting nutrition, healthcare access and education all of which have long term implications for NTD management and control. CONCLUSIONS: The COVID-19 pandemic profoundly impacted global health research and global health equity. Attention and funding were diverted from all sectors, significantly affecting research and development efforts set out in the World Health Organization's NTD elimination Roadmaps. Ongoing changes to funding, economic crises, logistics and supply chain disruptions as well as deepening poverty has put a strain on already weak healthcare systems and exacerbated LMIC healthcare challenges. In particular, the delays and constraints to NTD management and elimination programs will have long-reaching consequences highlighting the need for global cooperation and renewed investment to put the NTD roadmap back on track. Targets and milestones are unlikely to be met without significant investment for recovery, in place.

Myalgic Encephalomyelitis/Chronic Fatigue Syndrome (ME/CFS) is a chronic, debilitating disease characterised by a wide range of symptoms that severely impact all aspects of life. Despite its significant prevalence, ME/CFS remains one of the most understudied and misunderstood conditions in modern medicine. ME/CFS lacks standardised diagnostic criteria owing to variations in both inclusion and exclusion criteria across different diagnostic guidelines, and furthermore, there are currently no effective treatments available. Moving beyond the traditional fragmented perspectives that have limited our understanding and management of the disease, our analysis of current information on ME/CFS represents a significant paradigm shift by synthesising the disease's multifactorial origins into a cohesive model. We discuss how ME/CFS emerges from an intricate web of genetic vulnerabilities and environmental triggers, notably viral infections, leading to a complex series of pathological responses including immune dysregulation, chronic inflammation, gut dysbiosis, and metabolic disturbances. This comprehensive model not only advances our understanding of ME/CFS's pathophysiology but also opens new avenues for research and potential therapeutic strategies. By integrating these disparate elements, our work emphasises the necessity of a holistic approach to diagnosing, researching, and treating ME/CFS, urging the scientific community to reconsider the disease's complexity and the multifaceted approach required for its study and management.

Cutaneous leishmaniasis (CL), a neglected tropical disease, is a major public health concern in Yemen, with Leishmania tropica identified as the main causative agent. This study aims to investigate the occurrence and distribution of Leishmania parasites in domestic and wild animals in CL endemic areas in the western highlands of Yemen. A cross-sectional study was conducted in the Utmah District of western Yemen. Blood and skin scraping specimens were collected from 122 domestic and wild animals and tested for the Leishmania DNA using internal transcribed spacer 1 (ITS1) nested polymerase chain reaction. Phylogenetic analyses were performed on 20 L. tropica sequences obtained from animals in this study and 34 sequences from human isolates (collected concurrently from the same study area) retrieved from the GenBank. Overall, L. tropica was detected in 16.4% (20/122) of the examined animals, including 11 goats, two dogs, two bulls, one cow, one donkey, one rabbit, one rat and one bat. None of the examined cats and sheep was positive. The animal sequences were segregated into four different L. tropica haplotypes, with the majority of the animal (15/20) and human (32/34) sequences composed of one dominant haplotype/genotype. These findings represent the first confirmed evidence of natural L. tropica infections in different kinds of domestic and wild animals in western Yemen, suggesting these animals potentially have a role in the transmission of CL in Yemen. Therefore, a One Health approach is required for the effective prevention and control of this devastating disease among endemic populations.

Neglected tropical diseases continue to cause a significant burden worldwide, with Africa accounting for more than one-third of the global burden. Over the past decade, progress has been made in eliminating, controlling, and eradicating these diseases in Africa. By December 2022, 47 out of 54 African countries had eliminated at least one neglected tropical disease, and more countries were close to achieving this milestone. Between 2020 and 2021, there was an 80 million reduction in people requiring intervention. However, continued efforts are needed to manage neglected tropical diseases and address their social and economic burden, as they deepen marginalisation and stigmatisation. Wastewater-based epidemiology involves analyzing wastewater to detect and quantify biomarkers of disease-causing pathogens. This approach can complement current disease surveillance systems in Africa and provide an additional layer of information for monitoring disease spread and detecting outbreaks. This is particularly important in Africa due to limited traditional surveillance methods. Wastewater-based epidemiology also provides a tsunami-like warning system for neglected tropical disease outbreaks and can facilitate timely intervention and optimised resource allocation, providing an unbiased reflection of the community's health compared to traditional surveillance systems. In this review, we highlight the potential of wastewater-based epidemiology as an innovative approach for monitoring neglected tropical disease transmission within African communities and improving existing surveillance systems. Our analysis shows that wastewater-based epidemiology can enhance surveillance of neglected tropical diseases in Africa, improving early detection and management of Buruli ulcers, hookworm infections, ascariasis, schistosomiasis, dengue, chikungunya, echinococcosis, rabies, and cysticercosis for better disease control.
