Abstract The classification of the legume family proposed here addresses long‐known non‐monophyly traditionally recognised subfamily Caesalpinioideae, by recognising six robustly supported monophyletic subfamilies. This new uses as its framework most comprehensive phylogenetic analyses legumes to date, based on plastid matK gene sequences, and including near‐complete sampling genera (698 currently 765 genera) ca. 20% (3696) known species. region has been widely sequenced across legumes, in...
Background The novel coronavirus disease 2019 (COVID-19) has infected 1.9% of the world population by May 2, 2021. Since most previous studies that examined risk factors for mortality and severity were based on hospitalized individuals, population-based cohort are called to provide evidence can be extrapolated general population. Therefore, we aimed examine associations comorbidities with in individuals COVID-19 diagnosed 2020 Ontario, Canada. Methods findings We conducted a retrospective...
<h3>Background:</h3> Unnecessary antibiotic use in the community Canada is not well defined. Our objective was to quantify unnecessary prescribing a Canadian primary care setting. <h3>Methods:</h3> We performed descriptive analysis Ontario from April 2011 March 2016 using Electronic Medical Records Primary Care database linked other health administrative data sets at ICES. determined rates (per 100 patient–physician encounters) for 23 common conditions and estimated of predefined expected...
Cirrhosis is the result of advanced scarring (or fibrosis) liver, and often diagnosed once decompensation with associated complications has occurred. Current non-invasive tests to detect liver fibrosis have limited performance, many indeterminate classifications. We aimed identify patients all-causes using machine learning algorithms (MLAs).In this retrospective study routinely collected laboratory, clinical, demographic data, we trained six MLAs (support vector machine, random forest...
Approximately 25% of outpatient antibiotic prescriptions are unnecessary among family physicians in Canada. Minimizing antibiotics is key for community stewardship. However, prescribing much harder to measure than total prescribing. We investigated the association between and use by evaluated inter-physician variability prescribing.This was a cohort study based on electronic medical records Ontario, Canada, April 2011 March 2016. used predefined expected rates 23 common primary care...
Premise of research. Cajaninae is the most speciose subtribe legume tribe Phaseoleae, comprising ca. 490 species distributed in 10 genera. The group characterized by peculiar secretory structures, such as bulbous-based trichomes and vesicular glands. taxonomic importance these structures Phaseoleae was considered earlier publications, although few taxa were included those studies. To evaluate on leaflets representatives Cajaninae, anatomical micromorphological studies performed.Methodology....
Abstract Located in the municipalities of Ouro Preto and Mariana, Quadrilátero Ferrífero (QF) Minas Gerais, Itacolomi State Park (ISP) shelters more than 7,000 ha remnants Atlantic Forest campos rupestres. The QF region has high biodiversity is being highly impacted, mainly by mining activities. Aiming to organize available floristic information support related research, this study presents list phanerogamic species ISP major vegetation types. This survey was carried out from October/1992...
Quantifying the potential cancer cases associated with environmental carcinogen exposure can help inform efforts to improve population health. This study developed an approach estimate burden of and applied it Ontario, Canada. The purpose was identify carcinogens greatest impact on support evidence-based decision making.We conducted a probabilistic assessment in Ontario. We selected 23 that we defined as "environmental" (e.g., pollutants) were relevant province, based select classifications...
Eriosema tozziae, a new species of Leguminosae (Papilionoideae, Phaseoleae, Cajaninae) from Minas Gerais is described and illustrated. Similar to E. defoliatum, it differs morphologically the latter by persistent leaves in reproductive phase (vs. caducous defoliatum) shorter inflorescences (10–13 cm long vs. 15–30 defoliatum). An identification key for also provided.
Eriosema grearii, a new species for the genus (Leguminosae, Papilionoideae, Phaseoleae, Cajaninae), is described and illustrated. Similar to E. heterophyllum, it differs from morphologically by free (vs. joined) stipules, lax flowers distributed along inflorescence axis congested concentrated at its apex), inflorescences not opposite leaves opposite), leaflets with secretory cells base of trichomes absence trichomes). A survey leaflet structures revealed that grearii has distinct structures,...
In Ontario, Canada, parents have the responsibility to report their child's routine infant and childhood vaccines provincial immunization registry (the Digital Health Immunization Repository; DHIR) without healthcare provider validation. Despite its use in coverage monitoring, no study has previously examined completeness of data within DHIR.We assessed DHIR immunizations, as compared immunizations Electronic Medical Records-Primary Care (EMRPC) database, also known EMRALD, a network family...
During a taxonomic study of Eriosema in Brazil, new species was discovered from the Chapada dos Veadeiros National Park, Goiás State. elegans is herein described and illustrated its morphological affinities with related discussed. The geographical distribution, conservation status, information about flowering fruiting are provided. Also, secretory structures leaflets morphologically E. glabrum carried out.
Objective Identify patterns in cervical cancer incidence Ontario according to neighborhood sociodemographic characteristics over time and by morphologic type. Methods Incident cases of diagnosed from 1991 2009 were obtained the Cancer Registry. Population data on Canadian Census. Age-standardized rates (ASIR) rate ratios (RRs) with 95% confidence intervals (CIs) calculated for each characteristic, stratified type (squamous cell carcinoma adenocarcinoma) period diagnosis. Results Incidence...
Pertussis is a reportable disease in many countries, but ascertainment bias has limited data accuracy. This study aims to validate pertussis measures using reference standard that incorporates different suspected case severities, allowing for the impact of severity on accuracy and detection be explored. We evaluated 25 algorithms primary care electronic medical record database between January 1, 1986 December 30, 2016. estimated sensitivity, specificity, positive predictive value (PPV),...
Eriosema macrostipulatum, a noteworthy new species from Goias State, was discovered during taxonomic study of the genus in Brazil. It is herein described, illustrated, and has its morphological anatomical affinities with related presented. The geographical distribution, conservation status, information about flowering fruiting are provided. Additionally, dichotomous key to taxa that occur Chapada dos Veadeiros National Park, Alto Paraiso de municipality (Goias State)
