RESUMO

Mystacagenia Evans, 1973 is a strictly Neotropical genus of pompilid wasps (Pepsinae: Ageniellini), restricted to rain forest areas. The genus comprises four described species: M. albiceps Evans, 1973 (Peru, Brazil), M. bellula Evans, 1973 (Peru), M. variegata Evans, 1973 (Brazil), and M. elegantula Evans, 1980 (Panama). Mystacagenia is scarce in collections, with only eight specimens registered, all of these females (Evans 1973, 1977, 1980; Cambra 1993; Corro Cambra 2011).

RESUMO

Agroforestry is hypothesised to increase ecological and economic functions of farms. Yet it is unclear if and how much agroforestry should be embedded in diversified farming systems to satisfy farmers' needs while potentially enhancing environmental services. To address this research gap we use a mathematical programming model to investigate the role of different agroforestry systems in hypothetical farm portfolios that reduce trade-offs between farmers' goals. Our approach is innovative because it simultaneously considers multiple objectives and the effect of land-use diversification within a farm, is based on knowledge and perceptions of local farmers, and accounts for heterogeneity in farmer judgement. We test the model in a forest frontier region in Eastern Panama, using data from farmer interviews. Farmers evaluated conventional land uses and two agroforestry systems (silvopasture and alley cropping) against 10 pre-defined socio-economic and ecological objectives. First we determined the optimal farm land-use composition that reduces trade-offs between the 10 objectives. The model selects the mix of land uses that secures the best worst-case performance across all objectives, when considering uncertainty in the ability of each land use to achieve each objective (which we quantify by the variability in farmer opinion). Agroforestry dominates the optimised farm portfolio, which comprises 60% silvopasture, 39% forest and 1% plantation. This land-use portfolio, however, deviates strongly from the current land use of farmers, which is 59% pasture, 26% crops, 14% forest and 1% plantation. In a second step we explore the implicit objectives driving farmers' current land-use decisions. We find that immediate-term needs related to food security and liquidity best explain farmers' current land-use portfolio; optimising for these objectives produces a land-use portfolio comprising 60% pasture and 40% crops, which is similar to the current land use. This suggests that increasing agroforestry adoption in the study area will require systems that provide early and frequent returns and allow for ongoing crop production, to better satisfy farmers' cash flow and household consumption needs.

RESUMO

BACKGROUND: An unmet clinical need remains for an effective tetravalent dengue vaccine suitable for all age groups, regardless of serostatus. We assessed the immunogenicity and safety of three different dose schedules of a tetravalent dengue vaccine (TAK-003) over a 48-month period in children living in dengue-endemic countries. METHODS: We did a large, phase 2, double-blind, placebo-controlled trial at three sites in the Dominican Republic, Panama, and the Philippines. Healthy participants aged 2-17 years were randomly assigned 1:2:5:1 using an interactive web response system with stratification by age to receive either a two-dose primary series (days 1 and 91), one primary dose (day 1), one primary dose plus booster (days 1 and 365), or placebo. Participants and relevant study personnel were masked to the random assignment until completion of the study at month 48. To maintain masking, TAK-003 recipients were administered placebo doses when appropriate. The primary objective was assessment of neutralising geometric mean titres for each serotype to month 48 assessed in the per-protocol immunogenicity subset. Secondary safety endpoints included proportions of participants with serious adverse events and symptomatic virologically confirmed dengue. This study is registered with ClinicalTrials.gov, NCT02302066. FINDINGS: Between Dec 5, 2014, and Feb 13, 2015, 1800 children were randomly assigned to the following groups: two-dose primary series (n=201), one primary dose (n=398), one primary dose plus 1-year booster (n=1002), and placebo (n=199). Of them, 1479 (82%) participants completed the 48-month study. Immunogenicity endpoints were assessed in 562 participants enrolled in the immunogenicity subset, of whom 509 were included in the per-protocol subset. At month 48, antibody titres remained elevated in all TAK-003 groups compared with placebo, irrespective of baseline serostatus. At month 48, geometric mean titres were 378 (95% CI 226-632) in two-dose, 421 (285-622) in one-dose, 719 (538-960) in one-dose plus 1-year booster, and 100 (50-201) in placebo recipients against DENV 1; 1052 (732-1511), 1319 (970-1794), 1200 (927-1553), and 208 (99-437) against DENV 2; 183 (113-298), 201 (135-298), 288 (211-392), and 71 (37-139) against DENV 3; and 152 (97-239), 164 (114-236), 219 (165-290), and 46 (26-82) against DENV 4; and tetravalent seropositivity rate was 89% (79-96), 86% (80-92), 97% (93-99), and 60% (47-72), respectively. Virologically confirmed dengue was recorded in 37 (2%) TAK-003 and 13 (7%) placebo participants, with a relative risk of 0·35 (0·19-0·65). No vaccine-related serious adverse events or severe dengue virus disease were reported. INTERPRETATION: TAK-003 elicited antibody responses against all four serotypes, which persisted to 48 months post-vaccination, regardless of baseline serostatus. No important safety risks were identified. We observed a long-term reduction in risk of symptomatic dengue virus disease in vaccinees. Results from this study provide a long-term safety database and support assessment of the vaccine in the ongoing phase 3 efficacy study. FUNDING: Takeda Vaccines.

RESUMO

BACKGROUND: A substantial unmet need remains for safe and effective vaccines against dengue virus disease, particularly for individuals who are dengue-naive and those younger than 9 years. We aimed to assess the efficacy, safety, and immunogenicity of a live attenuated tetravalent dengue vaccine (TAK-003) in healthy children aged 4-16 years. METHODS: We present data up to 18 months post-vaccination from an ongoing phase 3, randomised, double-blind trial of TAK-003 in endemic regions of Asia and Latin America (26 medical and research centres across Brazil, Colombia, Dominican Republic, Nicaragua, Panama, Philippines, Sri Lanka, and Thailand). Healthy children aged 4-16 years were randomly assigned 2:1 (stratified by age and region) to receive two doses of TAK-003 or two doses of placebo, 3 months apart. Investigators, participants and their parents or guardians, and sponsor representatives advising on trial conduct were masked to trial group assignments. Participants presenting with febrile illness were tested for virologically confirmed dengue (VCD) by serotype-specific RT-PCR. In timeframes beginning 30 days post-second dose, the primary endpoint (overall vaccine efficacy) was assessed in the first 11 months, and the secondary endpoints (efficacy by baseline serostatus, serotype, hospitalised dengue, and severe dengue) in the first 17 months. This study is registered with ClinicalTrials.gov, NCT02747927. FINDINGS: 20 099 participants were randomly assigned and vaccinated between Sept 7, 2016, and Aug 18, 2017; 19 021 (94·6%) were included in the per protocol analysis, and 20 071 (99·9%) in the safety set. The primary endpoint was achieved with an overall vaccine efficacy of 80·2% (95% CI 73·3 to 85·3; 61 cases of VCD in the TAK-003 group vs 149 cases of VCD in the placebo group). In the secondary endpoint assessment timeframe, an overall vaccine efficacy of 73·3% (95% CI 66·5 to 78·8) was observed. Analysis of secondary endpoints showed efficacies of 76·1% (95% CI 68·5 to 81·9) in individuals who were seropositive at baseline, 66·2% (49·1 to 77·5) in individuals who were seronegative at baseline, 90·4% (82·6 to 94·7) against hospitalised dengue, and 85·9% (31·9 to 97·1) against dengue haemorrhagic fever. Efficacy varied by individual serotypes (DENV 1, 69·8% [95% CI 54·8 to 79·9]; DENV 2, 95·1% [89·9 to 97·6]; DENV 3, 48·9% [27·2 to 64·1]; DENV 4, 51·0% [-69·4 to 85·8]). Cumulative rates of serious adverse events were similar in TAK-003 (4·0%) and placebo (4·8%) recipients, and were consistent with expected medical disorders in the study population. Infection was the most frequent reason leading to serious adverse events. 20 participants (<0·1% of the safety set) were withdrawn from the trial due to 21 adverse events by the end of part two; 14 of these participants received TAK-003 and six received placebo. INTERPRETATION: TAK-003 was well tolerated and efficacious against symptomatic dengue in children regardless of serostatus before immunisation. Vaccine efficacy varied by serotype, warranting continued follow-up to assess longer-term vaccine performance. FUNDING: Takeda Vaccines.

RESUMO

INTRODUCTION: Hantaviruses are a group of single-stranded RNA viruses carried by small rodent reservoirs, transmitted to humans through inhalation of aerosolized particles of rodent feces, urine, or saliva. In Panama, the Choclo orthohantavirus has been associated with Hantavirus Pulmonary Syndrome (n = 54) and Hantavirus Fever (n = 53). In 2018, there were 107 cases of hantavirus diseases, the majority in the Tonosí district, and 4 deaths. As there is no vaccine or treatment for hantavirus, proper prevention measures by community members is key to stopping outbreaks. METHODOLOGY AND PRINCIPAL FINDINGS: We investigated hantavirus knowledge, attitudes, and practices in one corregimiento of Tonosí, Panama to determine what factors influence uptake of prevention practices and high level of knowledge. We conducted a cross-sectional survey with 124 residents covering hantavirus knowledge, attitudes based in the Health Belief Model (perceived severity, perceived susceptibility, perceived obstacles, perceived benefits, and cues to action) and prevention practices. There was an overall high level of knowledge (median score: 4/6), though 20% did not know the route of transmission. The mean number of reported practices performed per person was 8.4 (range: 4-12). Most people had heard of hantavirus through other community members. In linear regression, lower perceived obstacles predicted higher preventive practice score. Reported obstacles to preventive practices included physical restrictions, such as age and health state. In ordinal logistic regression, higher education level and knowing more people who had previously been sick with hantavirus contributed to higher knowledge score. CONCLUSIONS: Future interventions should focus on removing barriers to performing preventive practices. As most people learned of hantavirus through community members, interventions should be community-based and involve those who have experienced the disease. Any future education materials should address confusions about route of transmission and be targeted at those with a lower education level.

RESUMO

El informe Seguridad social en Centroamérica y República Dominicana: situación actual y desafíos ofrece una descripción general de los principales regímenes vigentes en los sistemas y las instituciones de seguridad social de Centroamérica y el Caribe, realiza un análisis comparativo de esos regímenes, y presenta los desafíos regionales en materia de seguridad social, junto con las metas y los indicadores conexos para el decenio 2018-2028. Más allá de la diversidad en cuanto a la madurez y el desarrollo de los arreglos institucionales de seguridad social de la región, es posible distinguir una serie de desafíos comunes que pueden abordarse utilizando como marco de referencia la Estrategia para el acceso universal a la salud y la cobertura universal de salud de la Organización Panamericana de la Salud del 2014. Algunos de ellos se relacionan con temas estructurales que requieren importantes transformaciones en términos de rectoría y gobernanza —como la segmentación de los sistemas y la fragmentación de los servicios, la ampliación del número de contribuyentes y un financiamiento adecuado a las necesidades de la población— y otros con la prestación de los servicios de salud —un aspecto que requiere la transición a una atención integral y el fomento de la articulación de los distintos niveles de atención a través de redes integradas—. Para la elaboración de este documento se han consultado documentos oficiales de las instituciones de seguridad social de los países miembros del CISSCAD, la legislación vigente en los países y normas de cada institución, y se ha recurrido a bases de datos y publicaciones de organismos internacionales. Este informe está dirigido a profesionales, académicos y expertos del sector de la salud y la protección social interesados en la evolución de los sistemas de seguridad social en la Región de las Américas. Brinda información y análisis de datos que representan aportes técnicos útiles para debatir y formular propuestas de mejoras en los institutos de seguridad social de toda la Región.

RESUMO

Trace metal and metalloid levels were measured in eggs of the NW Atlantic leatherback turtle (Dermochelys coriacea) from nesting grounds in the Bocas del Toro province, Panama, to infer exposure and associated risks to local communities. Samples were analyzed for a set of 26 essential and non-essential elements using inductively coupled plasma techniques. Median concentrations of Fe, Zn, As, Se and Sr in D. coriacea eggs were higher than previously reported for this species, which likely reflects differential contamination levels of specimens during foraging. The evaluation of non-carcinogenic human health risks from ingesting leatherback eggs has revealed potential deleterious effects due to high concentrations of As, Se and Sr for all examined age and gender groups, while Hg and Zn levels were above international standards for children. Hazard index (HI) values exceeded unity in all cases indicating serious health impacts related to possible additive effects of multiple metals co-occurring in the eggs. Our findings suggest that exposure to high (inorganic) As and Cr(VI) levels is associated with an increased carcinogenic risk, significantly exceeding the acceptable lifetime risk of 10-6 for both adults and children. Despite some limitations, such as unclear As and Cr speciation, our results demonstrated that the ingestion of D. coriacea eggs poses considerable health risks to local communities, and their consumption should not exceed 3.4 × 10-4 g (5.0 × 10-6 eggs) kg BW d-1. Resource managers and conservationists should focus their attention to human health effects as an alternative tool to address egg poaching and consumption.

RESUMO

In 2019 the International Federation of Gynecology and Obstetrics (FIGO) embarked on an initiative that aims to strengthen the capacity of 10 national societies of obstetrics and gynecology (ObGyn) in advocacy for safe abortion. In 2018 needs assessments that entailed a desk study, interviews, and stakeholder workshops were conducted in Benin, Cameroon, Côte d'Ivoire, Kenya, Mali, Mozambique, Panama, Peru, Uganda, and Zambia. The general aim of the needs assessments was to gain a deeper understanding of the contextual situation and identify the needs of ObGyn societies in relation to safe abortion advocacy. This paper provides a cross-country analysis of the outcomes of the needs assessments and reflects on the capabilities, barriers, and opportunities to strengthen this role of ObGyn societies. Common barriers, such as unavailability of services, lack of technical guidance, unawareness and ambiguity about the legal framework, provider attitudes, and abortion stigma, pose challenges for ObGyn societies to work constructively on safe abortion advocacy. However, ObGyn societies have a strong position due to their strategic networks and technical credibility and can be a facilitator in healthcare providers' advocacy role. Five strategies were developed to strengthen the capacity of ObGyn societies in safe abortion advocacy.

RESUMO

This study elucidated the characteristics of climatological seasonal changes in the diurnal variations of precipitation at four ground stations in the upper Río Chagres basin in the Panama Canal watershed. The seasonal changes differed among the stations, although they are located within an area of only 414 km2. Precipitation peaks in the early afternoon at 1500 local standard time (LST) were observed at all the stations. At Chamon, monthly-mean hourly precipitation at every hour exceeded 0.3 mm h-1 throughout November and December. The occurrence of morning precipitation in January and March distinguished the seasonal precipitation pattern at Esperanza from the pattern at the other stations. Analyses of the seasonal changes in the diurnal variation with pattern correlations and rotational empirical orthogonal functions grouped the stations into two pairs: no morning peak at Chico and Río Piedras in the downstream basin and morning peak at Chamon and Esperanza in the upstream basin.

RESUMO

The Hydroscaphidae ("skiff beetles") is a family of minute aquatic beetles within the suborder Myxophaga comprising four genera: Hydroscapha Le Conte, 1874; Scaphydra Reichardt, 1973; Yara Reichardt Hinton, 1976 and Confossa Short et al., 2015. All genera are found within the Neotropical region, with the exception of Hydroscapha, which is widespread. Representatives of this family have been reported for Venezuela, Brazil, Panama (Short et al. 2015) and Nicaragua (Raudez et al. 2019).

RESUMO

Two new species of Anacroneuria are described. Anacroneuria bandido sp. n. is described from Coclé and Veraguas provinces of central Panama, and A. tuberculata sp. n. is proposed to provide a new name for a species previously identified from Costa Rica as A. magnirufa Jewett, 1958. New locality records are presented for eight species previously reported from Panama. The female of one species from Bocas del Toro province is described under an informal designation. There are now 26 recognized species of Plecoptera known from Panama.

RESUMO

Recent efforts have been taken to survey and describe the ascidian fauna of the Pacific and Atlantic coasts of Panama; however, the genus Pyura still remains poorly known. Sampling events have been occurring since 2003. In this research, we describe two new species from the Atlantic coast of Panama: P. longispina sp. nov., P. lopezlegentilae sp. nov., and two new species from the Pacific Coast of Panama: P. carmanae sp. nov. and P. imesa sp. nov. We also supply a tabular key for all the Pyura species found in Panama.

RESUMO

Larva, subimago, imago and eggs of Guajirolus ektrapeloglossa Flowers 1985 are described based on reared males and females from the type locality in Panama and a reared female from Peru. Structure and development of male genitals testify that the Neotropical taxon Guajirolus/g1 (incl. Chane) does not belong to Labiobaetini Kluge Novikova 2016 and, therefore, is not related to the Afrotropical genus Pseudopannota Waltz McCafferty 1987. At the same time, larvae of Guajirolus have striking similarity with that of Pseudopannota. The existent descriptions of Guajirolus nanus Lugo-Ortiz McCafferty 1995, G. queremba Nieto 2003 and G. flowersi Thomas Dominique (in Thomas, Dominique Orth) 2005 do not contain characters allowing to distinguish them from G. ektrapeloglossa. Thus, new synonymy is proposed: G. ektrapeloglossa (= G. nanus syn. n.; G. queremba syn. n.; G. flowersi syn. n.). Among the characters described as species-specific for Guajirolus rondoni Salles 2007, only the shape of labial palps allows to distinguish it from G. ektrapeloglossa.

RESUMO

The fire coral Millepora platyphylla Hemprich Ehrenberg, 1834 (Cnidaria, Hydrozoa) has a widespread Indo-Pacific distribution observed from the surface to 40 m (Razak Hoeksema 2003). However, its extirpation from the East Pacific (Gulf of Chiriqui, Panama) was documented after the 1982-1983 bleaching event (Glynn Weerdt 1991). Here, we report the discovery of 5 colonies of M. platyphylla from the eastern Pacific, specifically at Clipperton Atoll, during the TARA Pacific expedition (www.taraexpeditions.org).

RESUMO

A new species of the laomediid mud shrimp genus Axianassa Schmitt, 1924, A. planioculus, is described and illustrated on the basis of a single male specimen from intertidal muddy sand flat of Kabira Bay, Ishigaki Island, southern Ryukyu Islands, Japan. Axianassa planioculus n. sp. is morphologically closest to A. mineri Boone, 1931, known from Pacific Panama, among the 11 known congeners, but is readily distinguished from the latter by the eyes being dorsally concealed by the rostrum, the subovate telson, the unarmed carpus of the maxilliped 3 and the unarmed uropodal endopod. The discovery of a new mud-shrimp species in an easily accessible habitat indicates that the shallow-water infaunal decapods are still relatively poorly known. A partial segment of the mitochondrial 16S rRNA gene was sequenced from the holotype for future genetic studies.

RESUMO

Nine new species of Duplominona and one new Pseudominona (Platyhelminthes, Proseriata, Monocelididae) are described from the Caribbean coast of Panama and from Puerto Rico.                Duplominona aduncospina n. sp.; D. terdigitata n. sp.; D. pusilla n. sp.; D. bocasana n. sp. (from Panama) and D. dissimilispina n. sp.; D. chicomendesi n. sp.; D. macrocirrus n. sp.; D. diademata n. sp.; D. puertoricana n. sp. (from Puerto Rico) can be distinguished from the numerous congeneric species based on fine details of the sclerotized structures of the copulatory organ. Duplominona aduncospina n. sp. is characterised by a cirrus provided with 3-4 rows of recurve spines, 2-3 µm long. D. terdigitata n. sp. shows a tripartite tail, and needle-shaped cirrus spines, 1.5-9 µm long. Cirrus spines of D. pusilla n. sp. are scale-like, 1.5-3 µm long. D. bocasana n. sp. has triangular spines, 1.5-6 µm long. D. dissimilispina n. sp. has needle-shaped spines, 3.5-15 µm long. D. chicomendesi n. sp. has a small cirrus, with few, strongly curved spines, 2-7.5 µm long. D. macrocirrus n. sp. has a large cirrus, provided with spines 3-9 µm long, with the longest spines placed medially. D. diademata n. sp. has a cirrus with two separate spiny areas, with spines 7-13 µm long. D. puertoricana n. sp. has a very long cirrus, with poorly sclerotised proximal spines, and distal spines to 6 µm long. A taxonomic key of the genus Duplominona is provided. Pseudominona cancan n. sp. from Panama differs from P. dactylifera from Bermuda, the only species known in the genus so far, for its shorter cirrus and fewer, triangular spines 3-5 µm long, and for the position of the vagina, close to mouth. A specimen attributed to P. dactylifera collected in Puerto Rico is described. Distribution of the new species suggests a complete separation of Panamanian and Puerto Rican proseriate fauna, confirming previous reports of restricted ranges and high endemicity of mesopsammic Platyhelminthes.

RESUMO

A new snapping shrimp, Alpheus perlas sp. nov., is described based on a single complete male specimen collected on a shallow mudflat at Casayeta Island in the Las Perlas Archipelago, Gulf of Panama. The new species belongs to the large A. edwardsii (Audouin, 1821) species group characterised essentially by the presence of two notches on the major chela palm, with the dorsal notch extending posteriorly on the mesial surface. Within the eastern Pacific members of the A. edwardsii group, A. perlas sp. nov. appears to be morphologically closest to A. latus Kim Abele, 1988 and A. burukovskyi Anker Pachelle, 2015. Alpheus perlas sp. nov. does not seem to be specially adapted for digging and may be inquiline of a larger burrowing host, which currently remains unknown.

RESUMO

The present study deals with five species of the alpheid shrimp genus Salmoneus Holthuis, 1955 from the tropical eastern Pacific. One of them is new to science and is described as Salmoneus tiburon sp. nov. The new species is presently known only from the Las Perlas Archipelago in Panama and can be distinguished from all other congeners by the dentition on the cutting edges of the major chela, with some dactylar teeth reminiscent of shark teeth. It is also one of the largest species of the genus, with the carapace length of both type specimens surpassing 8.0 mm. Salmoneus serratidigitus (Coutière, 1897), a species with an ample distribution across the Indo-Pacific, is recorded for the first time from the Pacific coast of Panama and is confirmed from Colombia. Salmoneus malagensis Anker Lazarus, 2015, previously known only from Bahía Málaga in Colombia, is recorded from Panama's Azuero Peninsula. The remaining two species, S. excavatus Anker, 2011 and S. alvarezi Anker Lazarus, 2015, are recorded regionally from Las Perlas Archipelago in Panama and Playa Tarcoles in Costa Rica, both for the first time since their original descriptions. An identification key to the five currently known eastern Pacific species of Salmoneus is provided. However, several immature and/or incomplete specimens herein preliminarily reported as Salmoneus spp., as well photographic records from southern California, USA, indicate the presence of further undescribed species in the eastern Pacific.

RESUMO

Apyratuca Galileo Martins, 2006 is synonymized with Rosalba Thomson, 1864, and three new species are described: Rosalba contracta, from Ecuador; R. venusta, from Ecuador; and R. skelleyi, from Bolivia. Tethystola alboangulata sp. nov. is described from Trinidad and Tobago, and Blabicentrus similis sp. nov. is described from Panama. Blabicentrus bellus (Galileo Martins, 2004) is recorded from Panama. The genus Pygmaeopsis Schaeffer, 1908, is transferred to Desmiphorini and Pygmaeopsis apicalis sp. nov. is described from Mexico. Pseudestola maculata sp. nov. is described from Costa Rica and Panama. Desmiphora cucullata Thomson, 1868, is considered a synonym of Desmiphora cirrosa Erichson, 1847.
