Perceptions on use of insecticide-treated bed nets to prevent malaria: a qualitative assessment in two rural districts of Zambézia province in Mozambique.

Background: Malaria prevention in Africa merits particular attention as the world strives toward a better life for the poorest. The insecticide-treated bed nets (ITNs) are one of the malaria control strategies that, due to their cost effectiveness, are largely used in the country. Data on the actual coverage and usage of bed nets is unreliable, as it is based only on administrative data from distributed ITNs. Objective: This study assesses knowledge about malaria and bed net use in two areas of high malaria transmission. Methods: A qualitative study was conducted in 6 (six) rural communities in two malaria high-burden districts in Zambézia province. About 96 adults were recruited from the communities and enrolled to participate in focus group discussions. Data were transcribed verbatim, coded, and thematically analyzed using Nvivo11.0. Results: Participants mentioned the mosquito as the only cause of malaria and that the use of bed nets was highlighted as the most proficient protection against mosquito bites and malaria. Children and pregnant women were described as being the priority groups to sleep under a bed net protection in the household. The use of bed nets was common among households, although not sufficient for the number of household members. In addition, the preservation of the nets was considered inadequate. Conclusions: The findings of this study highlight the need to increase public knowledge about malaria and nets and to strengthen the communication and logistics component of the net distribution campaign to ensure that households have enough nets for their members and use them appropriately.

Impact of genus (Geotrigona, Melipona, Scaptotrigona) in the targeted 1H-NMR organic profile, and authenticity test by interphase emulsion of honey processed in cerumen pots by stingless bees in Ecuador.

The biodiversity of Ecuadorian stingless bees is almost 200 species. Traditional pot-honey harvest in Ecuador is mostly done from nests of the three genera selected here Geotrigona Moure, 1943, Melipona Illiger, 1806, and Scaptotrigona Moure, 1942. The 20 pot-honey samples collected from cerumen pots and three ethnic honeys "abeja de tierra", "bermejo", and "cushillomishki" were analyzed for qualitative and quantitative targeted 1H-NMR honey profiling, and for the Honey Authenticity Test by Interphase Emulsion (HATIE). Extensive data of targeted organic compounds (41 parameters) were identified, quantified, and described. The three honey types were compared by ANOVA. Amino acids, ethanol, hydroxymethylfurfural, aliphatic organic acids, sugars, and markers of botanical origin. The number of phases observed with the HATIE were one in Scaptotrigona and three in Geotrigona and Melipona honeys. Acetic acid (19.60 ± 1.45 g/kg) and lactic acid (24.30 ± 1.65 g/kg) were particularly high in Geotrigona honey (in contrast to 1.3 g/kg acetic acid and 1.6 g/kg lactic acid in Melipona and Scaptotrigona), and with the lowest fructose + glucose (18.39 ± 1.68) g/100g honey compared to Melipona (52.87 ± 1.75) and Scaptotrigona (52.17 ± 0.60). Three local honeys were tested using PCA (Principal Component Analysis), two were assigned with a correct declared bee origin, but "bermejo" was not a Melipona and grouped with the Scaptotrigona cluster. However after HCA (Hierarchical Cluster Analysis) the three honeys were positioned in the Melipona-Scaptotrigona cluster. This research supports targeted 1H-NMR-based profiling of pot-honey metabolomics approach for multi-parameter visualization of organic compounds, as well as descriptive and pertained multivariate statistics (HCA and PCA) to discriminate the stingless bee genus in a set of Geotrigona, Melipona and Scaptotrigona honey types. The NMR characterization of Ecuadorian honey produced by stingless bees emphasizes the need for regulatory norms. A final note on stingless bee markers in pot-honey metabolites which should be screened for those that may extract phylogenetic signals from nutritional traits of honey. Scaptotrigona vitorum honey revealed biosurfactant activity in the HATIE, originating a fingerprint Honey Biosurfactant Test (HBT) for the genus in this set of pot-honeys.

Evidence of floral rewards in Brasiliorchis supports the convergent evolution of food-hairs in Maxillariinae.

PREMISE: Angiosperms distributed over a large geographical area may display considerable phenotypic variation that can be recognized at morphological and micromorphological levels. Here, we investigate the pollination biology and the presence of floral rewards in Brazilian populations of the widely distributed orchid, Brasiliorchis picta. Based on the new data presented here this study investigates the evolution of floral rewards in Maxillariinae, and tests for the occurrence of convergent evolution of food-hairs in this subtribe. METHODS: Micromorphological and histochemical analyses of the labellar tissues were conducted, together with chemical analysis of fragrance and experiments involving the use of chemical baits. The evolution of floral rewards in Maxillariinae were addressed. RESULTS: Microscopy revealed that B. picta offers food-hairs as a reward. Fragrance is produced by abaxially located labellar epidermal papillae. The main compound present in our samples (2-phenylethanol) also occurs in the aggregation pheromone produced by the mandible glands of pollinators, Meliponini bees. Our analyses indicate a high diversity of flower rewards and pollinators displayed by members of Maxillariinae, and support that edible trichomes evolved independently five times in the subtribe. CONCLUSIONS: The high diversity of floral rewards and pollinators displayed by members of Maxillariinae suggests that different pollinator pressures are involved in the evolution of this neotropical subtribe. In addition, the offering of food-hairs, which are generally infrequently encountered in Orchidaceae, arose by convergent evolution in Maxillariinae.

A Structural Connectivity Disruption One Decade before the Typical Age for Dementia: A Study in Healthy Subjects with Family History of Alzheimer's Disease.

The concept of the brain has shifted to a complex system where different subnetworks support the human cognitive functions. Neurodegenerative diseases would affect the interactions among these subnetworks and, the evolution of impairment and the subnetworks involved would be unique for each neurodegenerative disease. In this study, we seek for structural connectivity traits associated with the family history of Alzheimer's disease, that is, early signs of subnetworks impairment due to Alzheimer's disease. The sample in this study consisted of 123 first-degree Alzheimer's disease relatives and 61 nonrelatives. For each subject, structural connectomes were obtained using classical diffusion tensor imaging measures and different resolutions of cortical parcellation. For the whole sample, independent structural-connectome-traits were obtained under the framework of connICA. Finally, we tested the association of the structural-connectome-traits with different factors of relevance for Alzheimer's disease by means of a multiple linear regression. The analysis revealed a structural-connectome-trait obtained from fractional anisotropy associated with the family history of Alzheimer's disease. The structural-connectome-trait presents a reduced fractional anisotropy pattern in first-degree relatives in the tracts connecting posterior areas and temporal areas. The family history of Alzheimer's disease structural-connectome-trait presents a posterior-posterior and posterior-temporal pattern, supplying new evidences to the cascading network failure model.

Age and APOE genotype affect the relationship between objectively measured physical activity and power in the alpha band, a marker of brain disease.

BACKGROUND: Electrophysiological studies show that reductions in power within the alpha band are associated with the Alzheimer's disease (AD) continuum. Physical activity (PA) is a protective factor that has proved to reduce AD risk and pathological brain burden. Previous research has confirmed that exercise increases power in the alpha range. However, little is known regarding whether other non-modifiable risk factors for AD, such as increased age or APOE ε4 carriage, alter the association between PA and power in the alpha band. METHODS: The relationship between PA and alpha band power was examined in a sample of 113 healthy adults using magnetoencephalography. Additionally, we explored whether ε4 carriage and age modulate this association. The correlations between alpha power and gray matter volumes and cognition were also investigated. RESULTS: We detected a parieto-occipital cluster in which PA positively correlated with alpha power. The association between PA and alpha power remained following stratification of the cohort by genotype. Younger and older adults were investigated separately, and only younger adults exhibited a positive relationship between PA and alpha power. Interestingly, when four groups were created based on age (younger-older adult) and APOE (E3/E3-E3/E4), only younger E3/E3 (least predicted risk) and older E3/E4 (greatest predicted risk) had associations between greater alpha power and higher PA. Among older E3/E4, greater alpha power in these regions was associated with improved memory and preserved brain structure. CONCLUSION: PA could protect against the slowing of brain activity that characterizes the AD continuum, where it is of benefit for all individuals, especially E3/E4 older adults.

Planning and implementation of a countrywide campaign to deliver over 16 million long-lasting insecticidal nets in Mozambique.

BACKGROUND: In 2016/2017, Mozambique conducted a countrywide long-lasting insecticidal nets (LLINs) universal coverage campaign (UCC). This paper aims to describe the planning and implementation process of the campaign in Mozambique. METHODS: A cross-sectional and descriptive design was used for reporting the planning and implementation process of the UCC. The UCC used a collaborative approach, involving institutional and non-institutional actors, namely: National Malaria Control Programme (NMCP), provincial and district health authorities, community members and civil society partners. A new household registration strategy based on coupons, stickers, and one LLIN per two persons as allocation criterion was implemented. The campaign was implemented in phases, allowing for continuous improvement of implementation quality by applying lessons learnt from each phase. RESULTS: A total of 7,049,894 households were registered corresponding to a total of 31,972,626 registered persons. A total of 16,557,818 LLINs were distributed between November 2016 and December 2017, corresponding to 97% of LLINs needs based on household registration, and covering 95% of the registered households (6,708,585 households), resulting in an estimated 85% of the total Mozambican population with LLIN access. CONCLUSIONS: The collaborative planning process and strong coordination of campaign actors allowed Mozambique's NMCP and partners to successfully carry out the first countrywide LLINs UCC in the country. The increased access to LLINs in households will likely result in increased LLIN use and a reduction of the malaria burden in the country, therefore contributing to the achievement of the 2016-2030 Global Technical Strategy for Malaria goals.

Ecuadorian honey types described by Kichwa community in Rio Chico, Pastaza province, Ecuador using Free-Choice Profiling

Abstract Pastaza is the largest and least populated province in Ecuador, with seven native indigenous nationalities. The Kichwas from the Rio Chico community live near to the capital city Puyo, are recognized for their knowledge on stingless honey bees. From the 400 species of Neotropical Meliponini that make honey in cerumen pots, almost 100 thrive in Southern Ecuador, and confer such biodiversity to pot-honey. In this study sensory characteristics of Ecuadorian false and genuine honeys with diverse entomological origin: Apis mellifera - light amber and amber, Geotrigona leucogastra, Melipona grandis and Scaptotrigona sp. (S. ederi np Schwarz) were investigated with Kichwa assessors (four female and four male, aged 18-62 years old). The panel was asked to taste and to identify sensory attributes of honey (appearance, taste, smell, aroma, mouthfeel, other tactile sensations), and to score their intensities in 10 cm unstructured line scales anchored with the words weak and strong, using the Free-Choice Profile methodology The Generalized Procrustes Analysis was used on the data. The first and second dimensions accounted for by 61.1% of the variance. In the descriptive sensory evaluation, darker honeys (amber A. mellifera, false and Geotrigona) were separated from (light amber A. mellifera, Melipona and Scaptotrigona) by the first dimension; whereas thicker honeys (A. mellifera and false) were discriminated from thinner honeys (Geotrigona, Melipona and Scaptotrigona) by the second dimension. The assessors were able to evaluate and differentiate honey types without previous sensory training. Remarkably, two Kichwa ladies immediately spit out the false honey, in contrast to an acceptance study on 18-honeys, where the false honey was scored among the preferred ones by 58 participants of the First Congress on Apiculture and Meliponiculture in Ecuador. Therefore, results suggest that Ecuadorian native Kichwas keep a sensory legacy of ancestral knowledge with forest products such as honey.

A new species of the stingless bee Trichotrigona (Hymenoptera: Apidae, Meliponini).

Trichotrigona camargoiana sp. nov. from Candeias do Jamari, Rondônia, Brazil is described and illustrated, along with nesting and behavior, as the second species of the rare and unusual genus Trichotrigona Camargo & Moure, 1983. The new species differs from T. extranea Camargo & Moure, 1983 by having plumose setae on the face and mesepisterna, wing setae predominantly yellow and black metatibia. The diagnosis for Trichotrigona is updated. As believed for T. extranea, T. camargoiana sp. nov. apparently does not store food and is a cleptobiotic social bee associated with Frieseomelitta.

Três espécies são reconhecidas: Melipona (Michmelia) fuliginosa Lepeletier, 1836, de larga distribuição, do Suriname e Guiana Francesa até o sudeste do Brasil e noroeste da Argentina, M. (Michmelia) titania Gribodo, 1893 (revalidado), endêmica do oeste da Amazônia, e M. (Michmelia) fallax sp. nov., do noroeste do Equador até a América Central. Melipona fuliginosa distingue-se pela pilosidade dos tergos metassomáticos II-V, tanto do macho como da operária, densa e plumosa, e pelo primeiro tarsômero da perna III do macho mais largo que longo. Em M. titania e M. fallax sp. nov., a pilosidade dos tergos II-V é escassa e simples, não-plumosa, e o primeiro tarsômero tão longo quanto largo ou mais longo que largo. Operárias de Melipona titania e M. fallax sp. nov. separam-se pela forma do penicilo, que é fortemente sinuoso em M. titania, e nos machos de M. fallax sp. nov. as órbitas internas dos olhos são paralelas, enquanto em M. titania as órbitas são convergentes embaixo. Novos registros geográficos, dados bionômicos e uma chave para identificação das espécies são apresentados. Adicionalmente, são feitos comentários sobre o padrão biogeográfico e sobre as glândulas tergais das rainhas.

Three species are recognized: Melipona (Michmelia) fuliginosa Lepeletier, 1836, widely distributed, from Suriname and French Guiana to southeastern Brazil and northwestern Argentina, M. (Michmelia) titania Gribodo, 1893 (revalidated), endemic to western Amazon and M. (Michmelia) fallax sp. nov., from northwestern Ecuador to Central America. Melipona fuliginosa differs from the other species by the pilosity of metasomal terga II-V, dense and plumose, in both male and workers, and the first tarsomere of leg III of the male wider than long. In M. titania and M. fallax sp. nov., the pilosity of terga II-V is scarce and simple, non-plumose, and the first tarsomere of leg III of the male is as long as wide or longer. Workers of Melipona titania and M. fallax sp. nov. differ by the shape of the penicillum, which is strongly sinuous in M. titania, and in the males of M. fallax sp. nov. the internal orbits of the eyes are parallel, while in M. titania the orbits are convergent below. New geographic records, bionomic data and an identification key for the species are presented. In addition, comments are given on geographic patterns and tergal glands of the queens.

Notas sobre a bionomia de Trichotrigona extranea Camargo & Moure (Hymenoptera, Apidae, Meliponini) / Notes on the bionomy of Trichotrigona extranea Camargo & Moure (Hymenoptera, Apidae, Meliponini)

Three nests of T. extranea, found in "igapó" forests in the locality of Samaúma, mouth of Daraã river (64°45'35" W, 0°27'7" S), AM, Brazil, are described and illustrated. This is the only place from where this species is known. All nests were located in hollow of dried branches of "Tanimbuca" - Buchenavia suaveolens Eichler (Combretaceae). Two of them were sharing the hollow with nests of Frieseomelitta sp. and one was solitary. One nest had 46 brood cells, 43 adult workers and one physogastric queen; the second one, 240 cells, 117 adult workers, 25 males and one physogastric queen; the third one, 260 cells, 163 workers, one physogastric queen and one queen pupa. The cells are arranged in clusters, like in Frieseomelitta, and the queen cells has the same shape and size as the worker ones. There are no food pots - this is the only known Meliponini that does not store food. Supposedly, this species is cleptobiotic. Queens and males are also described.

Meliponini neotropicais: o gênero Partamona Schwarz, 1939 (Hymenoptera, Apidae, Apinae) - bionomia e biogeografia / Neotropical Meliponini: the genus Partamona Schwarz, 1939 (Hymenoptera, Apidae, Apinae) - bionomy and biogeography

This work, dedicated to the study of nesting habits of the species of the Neotropical genus Partamona Schwarz, is a sequence to the taxonomic revision recently published elsewhere. A total of 214 nests and nest aggregations of 18 species [Partamona epiphytophila Pedro & Camargo, 2003; P. testacea (Klug, 1807); P. mourei Camargo, 1980; P. vicina Camargo, 1980; P. auripennis Pedro & Camargo, 2003; P. combinata Pedro & Camargo, 2003; P. chapadicola Pedro & Camargo, 2003; P. nhambiquara Pedro & Camargo, 2003; P. ferreirai Pedro & Camargo, 2003; P. pearsoni (Schwarz, 1938); P. gregaria Pedro & Camargo, 2003; P. batesi Pedro & Camargo, 2003; P. ailyae Camargo, 1980; P. cupira (Smith, 1863); P. mulata Moure in Camargo, 1980; P. seridoensis Pedro & Camargo, 2003; P. criptica Pedro & Camargo, 2003; P. helleri (Friese, 1900)] were studied , including data about habitat, substrate, structural characteristics, construction materials and behavior. The descriptions of the nests are illustrated with 48 drawings. Partial data of the nests of P. bilineata (Say, 1837), P. xanthogastra Pedro & Camargo, 1997, P. orizabaensis (Strand, 1919), P. peckolti (Friese, 1901), P. aequatoriana Camargo, 1980, P. musarum (Cockerell, 1917) and P. rustica Pedro & Camargo, 2003 are also presented.
