RESUMO

Purpose of Review: Despite the availability of effective vaccines against the three primary pathogens (Streptococcus pneumoniae, Haemophilus influenzae type b, and Neisseria meningitidis) that cause bacterial meningitis, this condition remains a significant cause of morbidity, neurologic sequelae, and mortality among children and adults living in low-income and middle-income countries. Recent Findings: Bacterial meningitis represents a significant public health challenge for national and global health systems. Since vaccine-preventable meningitis remains highly prevalent in low-income and middle-income countries, the World Health Organization (WHO) recently developed a global roadmap to defeating meningitis by 2030 and ameliorating its associated neurological sequelae. Summary: There is a need for a global approach to surveillance and prevention of bacterial meningitis. Increasing vaccination coverage with conjugate vaccines against pneumococcus and meningococcus with optimal immunization schedules are high-value healthcare interventions. Additionally, overcoming diagnostic challenges and the early institution of empirical antibiotic therapy and, when feasible, adjunctive steroid therapy constitutes the pillars of reducing the disease burden of bacterial meningitis in resource-limited settings.

RESUMO

Fabry disease (FD) is a multisystem lysosomal storage disorder induced by genetic variants in the alpha-galactosidase A (αGalA) gene. Some FD patients have GLA variants with a reduction in overall αGalA enzymatic activity due to mutated proteins with reduced stability, caused by protein misfolding and premature degradation, but the αGalA catalytic activity remains conserved ("amenable" genetic variants). To correct this misfolding and to prevent premature degradation, migalastat, a small iminosugar molecule was developed. We report the clinical characteristics of FD "amenable" cohort patients from Argentina, prior to starting treatment with migalastat. Seventeen Fabry adult patients were recruited from 13 Argentinian Centers; 8 males (47.1%) and 9 females (52.9%) were included. All genotypes included were missense-type "amenables" mutations. Some classic FD typical early manifestations were more frequent in patients with "classic" versus "late-onset" FD phenotype (pain, p=0.002; cornea verticillata, p=0.019). There was a statistically significant difference in estimated glomerular filtration rate in the "classic" versus "late-onset" phenotype (p=0.026) but no difference between genders (p=0.695). Left ventricular mass was similar between genders (p=0.145) and phenotypes (p=0.303). Cardiovascular risk factors were present among "late-onset" females (obesity 50% and smoke 25%). In patients who started "de novo" migalastat, the main indications were (i) heart disease, (ii) kidney damage, and (iii) pain, while in "switched from prior enzyme replacement therapy" patients, the most frequent indication was "patient decision;" this coincides with publications by other authors.

RESUMO

Background: Cancer genomics, as an interdisciplinary research area within the Global Cancer Research agenda, genomics and precision medicine, its important in research and clinical practice in Latin America. To date, there has been no study investigating evolution of this area in this region. The aim of this study was to evaluate for first time, the historical evolution of cancer genomics research in Latin America. Methods: Bibliometric cross-sectional study of documents on cancer genomics published by Latin American authors until 2023 in Scopus was performed. Statistical and visual analysis was performed with R programming language. Results: A total of 1534 documents were obtained. The first document of cancer genomics research was published in 1997, marking the inception of a 26-year evaluation period that extended until 2023. Among the documents, 74.3% (n = 1140) constituted original articles, followed by 22.7% (n = 349) classified as reviews. International collaboration was observed in 6.5% (n = 100) of the articles. Within the compilation of the ten most prolific authors in this region, 90% of them are from Brazil. This observed pattern extends to affiliations as well, wherein the Universidade de São Paulo emerges as the most active institution (n = 255 documents). This arrangement firmly establishes Brazil's prominence as the preeminent country in the region concerning cancer genomics research, showcasing robust collaboration networks both regionally and intercontinentally. An important transition in the studied hot topics over the last 20 years was identified, from the exploration of the human genome and the characterization of genomic and proteomic cancer profiles (1997-2010) to an in-depth investigation of cancer stem cells and personalized medicine (2011-2023). Among the array of cancer types under study, predominant attention has been directed towards breast, lung, prostate, and leukemia. Conclusion: Over the course of the past 26 years, a favorable and notable evolution has characterized cancer genomics research within Latin America, with Brazil leading the way, which possess a robust network of regional and intercontinental collaboration. Furthermore, the lines of research and hot topics have change in harmony with the region's objectives, strategies, and requisites.

RESUMO

The spotted wing drosophila, Drosophila suzukii Matsumura, is native to Southeast Asia and has become a serious pest of soft-skinned fruits worldwide. Several control methods are being tested worldwide as part of an integrated pest management approach. Biological control is a promising alternative tactic that can be used to manage D. suzukii populations, especially in unmanaged areas. This study aimed at exploring the diversity of resident hymenopteran parasitoids of drosophilids in northwestern Patagonia, where D. suzukii is considered an important pest. The survey also aimed to investigate possible associations between parasitoids and D. suzukii in several crops and non-crop fruits, and to determine D. suzukii fruits infestation levels. Fourteen sites with mainly berry crops were sampled biweekly using cider vinegar traps and collecting fresh fruits from a variety of crop and non-crop fruit plants. We identified five species of hymenopteran parasitoids, obtained from the baited traps, that have the potential to associate with D. suzukii: Leptopilina heterotoma Thomson, Ganaspis brasiliensis Ihering, Hexacola hexatoma Hartig (Figitidae), Pachycrepoideus vindemmiae Rondani (Pteromalidae), and Spalangia endius Walker (Spalangiidae). Leptopilina heterotoma is reported for the first time in Argentina. High numbers of D. suzukii adults were recovered from baited traps and field-collected fruits. However, no parasitoid emerged from D. suzukii pupae recovered from fruits, nor were any dead parasitoids recorded inside D. suzukii pupae. Overall infestation levels of D. suzukii on field-collected fruits did not differ significantly between species/varieties. The results are discussed with emphasis on the possible functionality and perspectives of using these species as biological control agents.

RESUMO

Sympatric-related species often exhibit resource partitioning. This can occur through different mechanisms, such as behavioral, morphological, and sensory variations, leading to qualitative, temporal, or spatial differences in resource exploitation, such as consuming different types of food. Sensory-based niche partitioning could be the underlying mechanism through which closely related species effectively reduce niche overlap. Here we ask whether variations in sensory responses to carbohydrates could reflect differences in the foraging patterns of two Vespula species present in Patagonia. For this, we established (i) the response thresholds toward carbohydrate solutions of foraging V. germanica and V. vulgaris in the laboratory, (ii) the sugar concentration of foraged carbohydrates in the field, and (iii) possible effects of incoming sugar concentration and performance at individual and colony levels. Results indicate a higher sucrose response threshold in V. germanica than V. vulgaris. Field results indicate that higher carbohydrate concentrations foraged by V. germanica, with 57% of V. germanica foragers returning with concentrations above 50% w/w, while only 23% of V. vulgaris foragers did so. These differences in sucrose sensitivity and foraging patterns positively correlate with colony size, irrespective of the species. Our results suggest that competition could be reduced in these closely related invasive social wasp species through sensory differences in their sugar perception levels, which would lead to them foraging different carbohydrate sources. This study suggests that sensory niche partitioning could promote species coexistence in these social wasps.

RESUMO

INTRODUCTION: Massive open online courses provide the opportunity to train health professionals and researchers from Latin America in global health. OBJETIVES: To determine the global offer of massive open online courses in global health and the characteristics of their content. MATERIAL AND METHODS: We examined massive open online course platforms to compile the global health offerings. The search had no time restriction and was last conducted in November, 2021. The search strategy only included the descriptor "global health". We obtained the characteristics of the courses, their content, and the global health domain covered. These data were analyzed using descriptive statistics, reporting absolute and relative frequencies. RESULTS: Our search strategy identified 4,724 massive open online courses. Of these, only 92 were related to global health. Most of these courses (n=44; 47.8%) were offered through Coursera. More than half (n=50; 54.4%) of the MOOCs were conducted by U.S.A. institutions and in English language (n=90; 97.8%). Most courses focused on "globalization of health and healthcare" (n=24; 26.1%), followed by the domains "capacity building" (n=16; 17.4%), "global burden of disease" and "social and environmental determinants of health" (n=15; 16.3%). CONCLUSIONS: We found a high offer of massive open online courses on global health. These courses covered the global health competencies required for health professionals.

RESUMO

Many people from poverty-stricken countries are migrating across South and Central America to reach the México-United States border, a movement exacerbated by the COVID-19 pandemic. Migrant people who begin their northbound journey in South America must transit across a significant geographic bottleneck, the Darién Gap, a mountainous rainforest region between Colombia and Panama. Most migrant people crossing this region originate from Cuba, Haiti, and Venezuela. Other people reach the shores of South American countries from west and central Africa or central and southeastern Asia and continue to the Darién Gap. Poverty and violence drive families with children to flee their homes and endure incalculable risks in their path. Children traveling with their families or as unaccompanied minors across the Darién Gap are exposed to life-threatening situations and human rights violations, including abuse, exploitation, malnourishment, and limited access to medical care. In addition to experiencing untreated medical illnesses, children experience mental health disorders during migration and after they reach their destination as a result of victimization and adverse traumatic experiences. Therefore, providing migrants, especially children, with rapid medical screenings and mental health support when they arrive at their destination is critical to reduce health inequities. Furthermore, making these interventions available during their transit and ensuring their safety may prevent further human rights abuses in children and families. Latin American governments must address the ongoing humanitarian crisis endured by migrants throughout their migratory path by offering access to essential healthcare services and safeguarding the rights and security of children and vulnerable groups.

RESUMO

BACKGROUND: Sirex noctilio is an invasive forest wasp that affects pines and can result in severe economic losses. The use of semiochemicals offers an opportunity to develop sensitive and specific capturing systems to mitigatenegative impacts. Previous research showed that female S. noctilio would use volatiles emitted by its fungal symbiont, Amylostereum areolatum, but little is known about how these modulate behaviour when combined with pine-wood emissions. Our aim was to understand the relevance of fungal volatiles grown on artificial media and wood from two hosts trees, Pinus contorta and Pinus ponderosa, on behavioural and electroantennographic responses of wasp females. Because background odours can modify an insect's response towards resource-indicating semiochemicals, we propose that the behaviour towards the symbiont (resource) will be modulated by host pine emissions (background odours). RESULTS: Olfactometric assays showed that both host species with fungus were attractive when contrasted against air (P. contorta versus Air, χ2 = 12.19, P < 0.001; P. ponderosa versus Air, χ2 = 20.60, P < 0.001) and suggest a clear hierarchy in terms of female preferences towards the tested stimuli, with response highest towards the fungus grown on P. contorta (olfactory preference index: 5.5). Electrophysiological analyses indicate that females detect 62 volatile compounds from the tested sources. CONCLUSION: Results indicate a strong synergy between symbiont and host semiochemicals, suggesting that the pine species could play a fundamental role in the interaction. Further understanding of the chemical basis of this, could guide the development of specific and attractive lures, in order to maximize attraction of wasps in surveillance programmes. © 2023 Society of Chemical Industry.

RESUMO

RESUMEN INTRODUCCIÓN En Argentina, la obesidad en adultos es una problemática con una prevalencia media de 25,4%. En la relación entre COVID-19 y obesidad, se observa mayor prevalencia de sobrepeso/obesidad y enfermedad severa entre los pacientes con COVID-19. Por ello, el objetivo del estudio fue conocer las características clínicas y epidemiológicas en pacientes con diagnóstico de obesidad sobrevivientes a la infección por SARS-CoV-2. MÉTODOS Se realizó un estudio observacional descriptivo y analítico de corte transversal. Se aplicó una encuesta autoadministrada. RESULTADOS La mediana de edad fue 41 años, y hubo un 69,9% de mujeres. Los síntomas de presentación más prevalentes fueron astenia (86,7%), anosmia (64,5%) y tos (64%). Con respecto a los síntomas persistentes luego de las 12 semanas del diagnóstico, los más prevalentes fueron astenia (52,9%), trastornos de sueño (32,4%) y falta de concentración/memoria (31,7%). Hubo mayor riesgo en mujeres (OR: 2,86; IC95%: 2,23-3,67) con obesidad (OR: 1,58; IC95%: 1,16-2,16). La enfermedad grave en obesos fue casi el triple comparado con no obesos (15,7% vs. 5,4%; p<0,001). DISCUSIÓN Los pacientes obesos mostraron síntomas de presentación que orientan a un estado inflamatorio sistémico, con disnea y tos más frecuentes, y tienen mayor prevalencia de enfermedad grave y neumonía, así como mayor riesgo de desarrollar síntomas persistentes, sobre todo si las personas son mujeres y sedentarias.


ABSTRACT INTRODUCTION In Argentina, obesity in adults is a problem with an average prevalence of 25.4%. The relationship between COVID-19 and obesity shows a higher prevalence of overweight/obesity and severe disease among patients with COVID-19. Therefore, the objective of the study was to know the clinical and epidemiological characteristics of patients diagnosed with obesity who survived SARSCoV- 2 infection. METHODS A descriptive and analytical cross-sectional observational study was carried out. A self-administered survey was applied. RESULTS The median age was 41 years and 69.9% were women. The most prevalent presenting symptoms were asthenia (86.7%), anosmia (64.5%) and cough (64%). Regarding persistent symptoms 12 weeks after diagnosis, the most prevalent ones were asthenia (52.9%), sleep disorders (32.4%) and lack of concentration/memory (31.7%). The risk was higher for women (OR: 2.865; CI95%: 2.23-3.67) with obesity (OR: 1.58; CI95%: 1.16-2.16). Severe disease in obese was almost threefold that in non-obese patients (15.7% vs. 5.4%; p<0.001). DISCUSSION Obese patients showed presenting symptoms that point to a systemic inflammatory state, with dyspnea and cough being more common, and have a higher prevalence of severe disease and pneumonia, as well as a higher risk of developing persistent symptoms, especially if they are women and sedentary.

RESUMO

Microbial infections resistant to conventional antibiotics constitute one of the most important causes of mortality in the world. In some bacterial species, such as Escherichia coli and Staphylococcus aureus pathogens, biofilm formation can favor their antimicrobial resistance. These biofilm-forming bacteria produce a compact and protective matrix, allowing their adherence and colonization to different surfaces, and contributing to resistance, recurrence, and chronicity of the infections. Therefore, different therapeutic alternatives have been investigated to interrupt both cellular communication routes and biofilm formation. Among these, essential oils (EO) from Lippia origanoides thymol-carvacrol II chemotype (LOTC II) plants have demonstrated biological activity against different biofilm-forming pathogenic bacteria. In this work, we determined the effect of LOTC II EO on the expression of genes associated with quorum sensing (QS) communication, biofilm formation, and virulence of E. coli ATCC 25922 and S. aureus ATCC 29213. This EO was found to have high efficacy against biofilm formation, decreasing-by negative regulation-the expression of genes involved in motility (fimH), adherence and cellular aggregation (csgD), and exopolysaccharide production (pgaC) in E. coli. In addition, this effect was also determined in S. aureus where the L. origanoides EO diminished the expression of genes involved in QS communication (agrA), production of exopolysaccharides by PIA/PNG (icaA), synthesis of alpha hemolysin (hla), transcriptional regulators of the production of extracellular toxins (RNA III), QS and biofilm formation transcriptional regulators (sarA) and global regulators of biofilm formation (rbf and aur). Positive regulation was observed on the expression of genes encoding inhibitors of biofilm formation (e.g., sdiA and ariR). These findings suggest that LOTCII EO can affect biological pathways associated with QS communication, biofilm formation, and virulence of E. coli and S. aureus at subinhibitory concentrations and could be a promising candidate as a natural antibacterial alternative to conventional antibiotics.

RESUMO

BACKGROUND: Understanding the factors that promote the success of invasive species is important for managing biological invasions. Interactions between invasives and other species (e.g. competitors, pathogens, or predators), could favor or limit their success. In recent decades, yellowjacket wasps, including Vespula germanica and Vespula vulgaris, have successfully established in Patagonia. Additionally, the invasive willow Salix fragilis has invaded areas next to watercourses, which in turn are typically colonized by the giant willow aphid (GWA, Tuberolagnus salignus), an additional species characterized as a successful invader in many regions worldwide. Aphid exudate (honeydew) has been reported to be used as a carbohydrate source by social wasps. The aim of our study was to gain a better understanding of the infestation pattern of the GWA in north-western Patagonia, its effect on exudate availability and its relationship with yellowjacket foraging patterns. The study was conducted under the working hypothesis that the increase in the size of GWA colonies and resulting honeydew production, will fuel an increase in local Vespula spp. RESULTS: We found that the aphid honeydew is produced in relatively high amounts in the region (estimated at 1517 ± 139 kg/ha/season), with strong indications that it is used by yellowjackets because of the significantly higher abundance levels of yellowjackets foraging on honeydew compared to nearby areas. CONCLUSION: Given its effect on yellowjacket foraging behavior, the interaction of these three invasive species, willows, GWA and yellowjackets, needs to receive special attention to develop future environmentally-sound mitigation tools of these nuisance pest. © 2023 Society of Chemical Industry.

RESUMO

Purpose of Review: Human African Trypanosomiasis (HAT), also known as sleeping sickness, is a vector-borne parasitic neglected tropical disease (NTD) endemic in sub-Saharan Africa. This review aims to enhance our understanding of HAT and provide valuable insights to combat this significant public health issue by synthesizing the latest research and evidence. Recent Findings: HAT has reached a historical < 1000 cases in 2018. In patients without neurologic symptoms and signs, the likelihood of a severe meningoencephalitic stage is deemed low, obviating the need for a lumbar puncture to guide treatment decisions using fexinidazole. Summary: Both forms of the disease, gambiense HAT (gHAT) and rhodesiense HAT (rHAT), have specific epidemiology, risk factors, diagnosis, and treatment. Disease management still requires a high index of suspicion, infectious disease expertise, and specialized medical care. Essential stakeholders in health policy are critical to accomplishing the elimination goals of the NTD roadmap for 2021-2030.

RESUMO

Introducción: La hernia diafragmática surge como resultado del movimiento de los órganos abdominales hacia el tórax a través de un defecto del diafragma resultante de varios tipos de lesiones, que a menudo representan un desafío diagnóstico y terapéutico. La hernia diafragmática traumática es una enfermedad infrecuente. El trauma diafragmático rara vez es aislado, la mayoría de las veces se acompaña de otras lesiones toracoabdominales, cerebrales o musculoesqueléticas, siendo estas comorbilidades más graves responsables del mal pronóstico y aumento de la mortalidad. Caso clínico: Anciana de 90 años de edad, hipertensa, quien inicia cuadro clínico 48 horas previas a su ingreso, cuando posterior a caída del plano de bipedestación presenta disminución del estado de consciencia, náuseas, vómitos y disnea en reposo. Rx de tórax evidencia asas intestinales en hemitórax derecho. Se realizó laparotomía exploradora. Conclusión: Las hernias diafragmáticas traumáticas son infrecuentes, con incidencia <3%, sintomatología inespecífica y relacionadas generalmente con lesiones asociadas al trauma. Siempre se debe sospechar de una HD ante un paciente con antecedente de trauma cerrado de alto impacto o penetrante, en función de la cinética y mecanismo de lesión. El diagnóstico supone un reto para el cirujano, debiendo apoyarse en una firme sospecha y estudios radiológicos. Su tratamiento es quirúrgico, debiendo ser individualizado, con abordajes torácicos o abdominales en función del caso. La técnica a emplear dependerá de las características del defecto, de la fase del diagnóstico y la experiencia del equipo quirúrgico(AU)


Introduction: Diaphragmatic hernia arises as a result of the movement of the abdominal organs towards the thorax through a defect in the diaphragm resulting from various types of injuries, which often represent a diagnostic and therapeutic challenge. Traumatic diaphragmatic hernia is a rare disease. Diaphragmatic trauma is rarely isolated, most of the time it is accompanied by other thoracoabdominal, brain or musculoskeletal injuries, these more serious comorbidities being responsible for the poor prognosis and increased mortality. Clinical case: A 90-year-old woman with hypertension , who began a clinical picture 48 hours prior to admission, when after falling from the standing plane he presented a decreased state of consciousness, nausea, vomiting, and dyspnea at rest. Chest x-ray shows intestinal loops in the right hemithorax. Exploratory laparotomy was performed. Conclusion: Traumatic diaphragmatic hernias are rare, with an incidence of <3%, non-specific symptoms, and generally related to injuries associated with trauma. HD should always be suspected in a patient with a history of high-impact or penetrating blunt trauma, depending on the kinetics and mechanism of injury. Diagnosis is a challenge for the surgeon, and must be based on a firm suspicion and radiological studies. Its treatment is surgical, and must be individualized, with thoracic or abdominal approaches depending on the case. The technique to be used will depend on the characteristics of the defect, the diagnostic phase and the experience of the surgical team(AU)

RESUMO

Introduction: Informatics applied to health sciences has brought cutting-edge solutions to healthcare problems. However, the number of health professionals trained in "Health Informatics" is low. Virtual education, such as massive online open courses, provide the opportunity for training in this field. Objective: To estimate the global offer of massive online open biomedical informatics courses and characterize their content. Methods: A search for massive online open courses was conducted throughout December 2021 on 25 platforms offering these courses. The search strategy included the terms "health informatics" and "biomedical informatics". The application areas of biomedical informatics, platform, institution, duration, time required per week, language, and subtitles available for each course were evaluated. Data were analyzed descriptively, reporting absolute and relative frequencies. Results; Our search strategy identified 1333 massive online open courses. Of these, only 79 were related to health informatics. Most of these courses (n = 44; 55.7%) were offered through Coursera. More than half (n = 55; 69.6%) were conducted by U.S. institutions in english (n = 76; 96.2%). Most courses focused on areas of translational bioinformatics (n = 27; 34.2%), followed by public health informatics (n = 23; 29.1%), and clinical research informatics (n = 13, 16.5%). Conclusions: We found a significant supply of massive online open courses on health informatics. These courses favor the training of more professionals worldwide, mostly addressing competencies to apply informatics in clinical practice, public health, and health research.
