Untangling biodiversity interactions: A meta network on pollination in Earth's most diverse tropical savanna.

Pollination is vital for ecosystem functioning, especially in biodiversity-rich regions like the Brazilian Cerrado. Our research establishes a comprehensive meta network of pollinator-plant interactions within this biome. We quantified the importance of different pollinator groups, identifying keystone species. We examined potential biases in sampling effort and the spatial behavior of interactions within the heterogeneous Cerrado plant physiognomies. Our investigation uncovered 1499 interactions among 293 plant species and 386 visitor species, with legitimate pollination accounting for 42.4% of the interactions. The network exhibited modularity, driven by bees and insects, with vertebrates bridging diurnal and nocturnal modules. While a generalized pattern emerged, high specialization existed within modules due to habitat diversity. Bees, particularly Apis mellifera (exotic) and Trigona spinipes (native), played central roles as network hubs. Hummingbirds and bats, engaged in specialized interactions showing strong connectivity within and between modules. Interestingly, invertebrate-vertebrate modules were more prevalent than expected in the meta network. However, a bias was evident, primarily within specific biogeographical districts with fragmented landscapes and intrusion from other biomes. Variations in plant species and endemism rates influenced pollinator occurrence and the Cerrado network topology. Our study offers valuable insights into pollinator-plant interactions within the Cerrado, encompassing both invertebrates and vertebrates. The modeled network represents a significant step in understanding the structural complexity of pollination networks, integrating partial networks from diverse pollination systems within heterogeneous habitats. Nevertheless, a biogeographical bias could limit a comprehensive understanding of network functionality across the Cerrado.

The influence of preeclampsia, advanced maternal age and maternal obesity in neonatal outcomes among women with gestational diabetes / A influência da pré-eclâmpsia, idade materna avançada e obesidade materna em desfechos neonatais entre mulheres com diabetes gestacional

Abstract Objective The present study aims to analyze adverse fetal or neonatal outcomes in women with gestational diabetes, including fetal death, preterm deliveries, birthweight, neonatal morbidity and mortality, as well as the synergic effect of concomitant pregnancy risk factors and poor obstetric outcomes, as advanced maternal age, maternal obesity and pre-eclampsia in their worsening. Methods The present cohort retrospective study included all pregnant women with gestational diabetes, with surveillance and childbirth at the Hospital da Senhora da Oliveira during the years of 2017 and 2018. The data were collected from the medical electronic records registered in health informatic programs Sclinico and Obscare, and statistical simple and multivariate analysis was done using IBM SPSS Statistics. Results The study participants included 301 pregnant women that contributed to 7.36% of the total institution childbirths of the same years, in a total of 300 live births. It was analyzed the influence of pre-eclampsia coexistence in neonatal morbidity (p = 0.004), in the occurrence of newborns of low and very low birthweight (p < 0.01) and in preterm deliveries (p < 0.01). The influence of maternal obesity (p = 0.270; p = 0.992; p = 0.684) and of advanced maternal age in these 3 outcomes was also analyzed (p = 0,806; p = 0.879; p = 0.985).Using a multivariate analysis, the only models with statistic significance to predict the three neonatal outcomes included only pre-eclampsia (p = 0.04; p < 0.01; p < 0.01). Conclusion Only coexistence of pre-eclampsia showed an association with adverse neonatal outcomes (neonatal morbidity, newborns of low and very low birthweight and preterm deliveries) and can be used as a predictor of them in women with gestational diabetes.

Suitability of enzymatic markers to assess the environmental condition of natural populations of Gambusia affinis and Daphnia magna--a case study.

In recent years, the use of biochemical markers, especially in the assessment of toxic effects and modes of action, under controlled laboratory conditions has increased. However, transposing their use to in situ monitoring or risk assessment evaluations has encountered barriers, mainly related to the difficulty in interpreting the meaning of biochemical variation. In this work, we aimed at understanding if biochemical marker activities (cholinesterase, glutathione S-transferase and lactate dehydrogenase) can be used to monitor the health status of natural populations of fish (Gambusia affinis) and daphnids (Daphnia magna). For that, two ponds with different water properties were chosen as study sites, and organisms collected at four sampling periods along the year. The pattern of biochemical marker responses was not the same in the two species, showing higher integrated biochemical marker response values in the winter for G. affinis and in the autumn for D. magna, suggesting specificities that must be taken into account in biomonitoring programmes by including representative species of several trophic levels. In the case of G. affinis, the differences in key physicochemical parameters between the two ponds (especially dissolved oxygen levels) did not seem to affect biochemical marker levels as if organisms were already perfectly adapted to their environment. In general, seasonal variation of water quality seems to have an important role on biochemical marker responses. Several parameters above Environmental Quality Standards were identified such as dissolved oxygen (DO), ammonia, nitrites, sulphides and metals, but eventual responses to these stressors could not be discriminated from natural variation except for particular cases.

Mycoplasma pneumoniae: a rare cause of vulvar ulcers or an undiagnosed one?

OBJECTIVES: Acute vulvar ulcers are quite common, and often, an etiological diagnosis cannot be achieved. This article reports 3 cases of vulvar ulcers in adult women infected with Mycoplasma pneumoniae. The authors were able to find only one similar report in the literature. MATERIAL AND METHODS: Two women in their third decade of life and 1 in the fourth presented to the hospital with acute and intense vulvar pain. Two of them reported oropharyngeal symptoms in the preceding days. All 3 presented with extensive, painful, and destructive vulvar ulcers. A standard protocol was applied, including samples taken from the ulcer (microbiology and polymerase chain reaction) and blood drawn for serological examination and liver function testing. All 3 had the remarkable finding of a positive immunoglobulin G (IgG) and IgM for M. pneumonia (in one of the cases, IgM was initially inconclusive but turned to positive when repeated 2 weeks later). One patient had an extensive destruction of one labium minus, requiring surgical reconstruction. RESULTS: Two of them were treated with antibiotics, and one was not. However, in fact, all 3 healed in a similar period, making it probable that this kind of medication is not helpful. CONCLUSIONS: M. pneumoniae might be associated with some cases of vulvar ulcers and should always be tested in this context. Probably, antibiotic treatment is not helpful, even when this agent is identified as the possible causal agent of vulvar ulcers.

Variáveis associadas ao desenvolvimento do bruxismo em crianças de 4 a 12 anos / Variables associated with the development of bruxism in children ranging from 4 to 12 years

Este estudo teve como objetivo avaliar o bruxismo infantil e as variáveis associadas ao desenvolvimento do mesmo. Os dados foram obtidos através de entrevista padronizada com o responsável pela criança e exame clínico. A prevalência do bruxismo foi de 41 por cento na amostra estudada. Os resultados sugerem uma associação do bruxismo com o comportamento da criança, presença de outros hábitos parafuncionais, patologias das vias aéreas superiores, desordem temporomandibular e perda de molares decíduos. Não foi encontrada associação entre bruxismo e fase de dentição, hábito de sucção digital, otite, bronquite e história de cárie interproximal

Diagnóstico de salud del distrito sanitario No. 3 año 1991 / Health diagnosis in the Sanitary District No. 3 year 1991

Teniendo presente que la misión de la universidad es la de formar profesionales con visión crítica de la realidad existente, que le permita establecer las estrategias y proponer alternativas válidas para lograr una mejor calidad de vida de la población, es que el equipo de trabajo abordó el diagnóstico de salud del Distrito Sanitario No.3 de Petare. De ese compromiso de la universidad con el estado, es por lo que la máxima casa de estudios autocríticamente debe rectificar su aislamiento con los sectores populares, incorporándose al trabajo democrático en y con la comunidad organizada. La universidad debe asumir el liderazgo en defensa de la vida humana y más allá de de la calidad de vida de los derechos humanos. En líneas generales debe estructurar la formación de gerentes de salud con una visión acorde a la realidad de las comunidades y servicios nacionales. En este orden de ideas se plantea que el profesional de hoy en día debe pasar a tener una actitud crítica participativa en su proceso de formación, asumiéndose que él es un recurso para el servicio de la salud que proyectado a la comunidad, al trabajo en equipo con otras disciplinas sea capaz de iunsertarse y de promover la propuesta de la APS para así poder mitigar la las condiciones de deterioro del nivel de vida de pobreza creciente y de inaccesibilidad a los servicios de salud a esa población para el año 2000. A través del desarrollo de la metodología empleada en el presente trabajo se pudo cumplir con las metas que se planteó la cátedra de administración Sanitaria y al mismo tiempo se pudo conocer los problemas inherentes al proceso salud-enfermedad tales como aspectos socio-culturales, aspectos demográficos, educativos, económicos, saneamiento ambiental que permiten una visión integral sobre la situación
