Siphonaptera of Canada
There are currently 154 species of fleas recorded in Canada in four superfamilies and seven families. Only two species have been added to the list since the previous summary by Holland (1979) one of which is unlikely to be established in Canada. There have been a number of significant nomenclatural changes since then most notable of which is the split of the Hystrichopsyllidae into two families Hystrichopsyllidae and Ctenophthalmidae. An additional 23 species may eventually be recorded based on presence of suitable hosts and proximity to known distributions. Six species are introduced and one species is adventive. Although total diversity is reasonably well known there are numerous gaps in distribution of fleas throughout the country. Barcode Index Numbers are available for only 22 species of fleas collected in Canada
Human Ophthalmomyiasis Interna Caused by Hypoderma tarandi, Northern Canada
Human myiasis caused by bot flies of nonhuman animals is rare but may be increasing. The treatment of choice is laser photocoagulation or vitrectomy with larva removal and intraocular steroids. Ophthalmomyiasis caused by Hypoderma spp. should be recognized as a potentially reversible cause of vision loss

Acari of Canada
Summaries of taxonomic knowledge are provided for all acarine groups in Canada, accompanied by references to relevant publications, changes in classification at the family level since 1979, and notes on biology relevant to estimating their diversity. Nearly 3000 described species from 269 families are recorded in the country, representing a 56% increase from the 1917 species reported by Lindquist et al. (1979). An additional 42 families are known from Canada only from material identified to family- or genus-level. Of the total 311 families known in Canada, 69 are newly recorded since 1979, excluding apparent new records due solely to classification changes. This substantial progress is most evident in Oribatida and Hydrachnidia, for which many regional checklists and family-level revisions have been published. Except for recent taxonomic leaps in a few other groups, particularly of symbiotic mites (Astigmata: feather mites; Mesostigmata: Rhinonyssidae), knowledge remains limited for most other taxa, for which most species records are unpublished and may require verification. Taxonomic revisions are greatly needed for a large majority of families in Canada. Based in part on species recorded in adjacent areas of the USA and on hosts known to be present here, we conservatively estimate that nearly 10,000 species of mites occur in Canada, but the actual number could be 15,000 or more. This means that at least 70% of Canadaβs mite fauna is yet unrecorded. Much work also remains to match existing molecular data with species names, as less than 10% of the ~7500 Barcode Index Numbers for Canadian mites in the Barcode of Life Database are associated with named species. Understudied hosts and terrestrial and aquatic habitats require investigation across Canada to uncover new species and to clarify geographic and ecological distributions of known species

Impact of primary kidney disease on the effects of empagliflozin in patients with chronic kidney disease: secondary analyses of the EMPA-KIDNEY trial
Background: The EMPA KIDNEY trial showed that empagliflozin reduced the risk of the primary composite outcome of kidney disease progression or cardiovascular death in patients with chronic kidney disease mainly through slowing progression. We aimed to assess how effects of empagliflozin might differ by primary kidney disease across its broad population. Methods: EMPA-KIDNEY, a randomised, controlled, phase 3 trial, was conducted at 241 centres in eight countries (Canada, China, Germany, Italy, Japan, Malaysia, the UK, and the USA). Patients were eligible if their estimated glomerular filtration rate (eGFR) was 20 to less than 45 mL/min per 1Β·73 m2, or 45 to less than 90 mL/min per 1Β·73 m2 with a urinary albumin-to-creatinine ratio (uACR) of 200 mg/g or higher at screening. They were randomly assigned (1:1) to 10 mg oral empagliflozin once daily or matching placebo. Effects on kidney disease progression (defined as a sustained β₯40% eGFR decline from randomisation, end-stage kidney disease, a sustained eGFR below 10 mL/min per 1Β·73 m2, or death from kidney failure) were assessed using prespecified Cox models, and eGFR slope analyses used shared parameter models. Subgroup comparisons were performed by including relevant interaction terms in models. EMPA-KIDNEY is registered with ClinicalTrials.gov, NCT03594110. Findings: Between May 15, 2019, and April 16, 2021, 6609 participants were randomly assigned and followed up for a median of 2Β·0 years (IQR 1Β·5β2Β·4). Prespecified subgroupings by primary kidney disease included 2057 (31Β·1%) participants with diabetic kidney disease, 1669 (25Β·3%) with glomerular disease, 1445 (21Β·9%) with hypertensive or renovascular disease, and 1438 (21Β·8%) with other or unknown causes. Kidney disease progression occurred in 384 (11Β·6%) of 3304 patients in the empagliflozin group and 504 (15Β·2%) of 3305 patients in the placebo group (hazard ratio 0Β·71 [95% CI 0Β·62β0Β·81]), with no evidence that the relative effect size varied significantly by primary kidney disease (pheterogeneity=0Β·62). The between-group difference in chronic eGFR slopes (ie, from 2 months to final follow-up) was 1Β·37 mL/min per 1Β·73 m2 per year (95% CI 1Β·16β1Β·59), representing a 50% (42β58) reduction in the rate of chronic eGFR decline. This relative effect of empagliflozin on chronic eGFR slope was similar in analyses by different primary kidney diseases, including in explorations by type of glomerular disease and diabetes (p values for heterogeneity all >0Β·1). Interpretation: In a broad range of patients with chronic kidney disease at risk of progression, including a wide range of non-diabetic causes of chronic kidney disease, empagliflozin reduced risk of kidney disease progression. Relative effect sizes were broadly similar irrespective of the cause of primary kidney disease, suggesting that SGLT2 inhibitors should be part of a standard of care to minimise risk of kidney failure in chronic kidney disease.

Amerodectes pheucticus sp. n. is close to A. passerinae Mironov and Chandler, 2017 from the Painted Bunting, Passerina ciris (Linnaeus, 1758) (Cardinalidae), in having the following: in both sexes, long spiculiform or narrowly lanceolate setae h3 (comparable in length to distance between them); in males, the aedeagus extending to the anterior end of anal slit, and the border of opisthoventral shields on lobes with a truncate denticle; and in females, the lobar shield split longitudinally. Amerodectes pheucticus differs by the following features: in males, the anterior part of the prodorsal shield has small ovate lacunae, the anterior corners of the hysteronotal shield are distinctly angular (not rounded), epimerites I are fused into a narrow U without any distinct stem, setae h3 are longer (45β48) and tarsus IV lacks an apical claw-like process; in females, the prodorsal shield has small circular lacunae in the posterior part; the lobar shields lack ornamentation and setae h1 are situated on the very margin of these shields. In males of A. passerinae, the prodorsal shield lacks ornamentation, the anterior corners of the hysteronotal shield are widely rounded, epimerites I are fused into a Y with a very short stem, setae h3 are shorter (35β38), and tarsus IV has a small apical claw-like process; in females, the prodorsal shield lacks ornamentation; each plate of the lobar shields has 2-3 circular lacunae in the anterior part, and setae h1 are distant from the anterior margins of these shields. Etymology. The specific epithet is taken from the generic name of the type host and is a noun in apposition.Published as part of Mironov, Sergey V. & Galloway, Terry D., 2021, Feather mites of the subfamily Pterodectinae (Acariformes: Proctophyllodidae) from passerines and kingfishers in Canada, pp. 1-55 in Zootaxa 5016 (1) on pages 16-20, DOI: 10.11646/zootaxa.5016.1.1, http://zenodo.org/record/522170

Alaudicola eremophila differs from A. bilobatus by the following features: in males, the lateral margins of the terminal cleft are distinctly divergent, the terminal cleft is shaped as an equilateral triangle; in females, the secondary spermaducts are 18β20 long, setae ps3 situated approximately at the level of the anterior one third of the anal slit. In males of A. bilobatus, the lateral margins of the terminal cleft are almost parallel, the whole terminal cleft is nearly U-shaped, and 8β10 wide at midlength; in females, the secondary spermaducts are 25β30 long, and setae ps3 are situated approximately at the midlength of the anal slit or slightly posterior. Etymology. The specific epithet is taken from the generic name of the type host and is a noun in apposition. Remark. The new species described above was previously reported from E. alpestris in Canada (Galloway et al. 2014: 170) under the name A. bilobatus.Published as part of Mironov, Sergey V. & Galloway, Terry D., 2021, Feather mites of the subfamily Pterodectinae (Acariformes: Proctophyllodidae) from passerines and kingfishers in Canada, pp. 1-55 in Zootaxa 5016 (1) on pages 38-42, DOI: 10.11646/zootaxa.5016.1.1, http://zenodo.org/record/522170

Trouessartia petrochelidon differs from T. quarta by the following features: in both sexes, the posterior part of the prodorsal shield bears a faint ornamentation of small lacunae; in males, the terminal lamellae are longer (20β25 Β΅m) and the idiosoma length is 420β475 Β΅m (Figs. 13A, 15E); in females, the proximal part of the primary spermaduct is regularly enlarged toward the head of spermatheca (Fig. 15H). In both sexes of T. quarta, the prodorsal shield lacks any distinct ornamentation; in males, the terminal lamellae are 16β18 Β΅m long, and the idiosomal length is 390β410 Β΅m; in females, the primary spermaduct is enlarged unequally, its part between the head of spermathecal and secondary spermaducts is 2 times wider than the part distal to the secondary spermaducts (Fig. 21D). Etymology. The specific epithet is taken from the generic name of the host and is a noun in apposition.Published as part of Mironov, Sergey V. & Galloway, Terry D., 2019, Feather mites of the genus Trouessartia Canestrini (Acariformes: Trouessartiidae) from swallows (Passeriformes: Hirundinidae) in Canada, pp. 1-39 in Zootaxa 4568 (1) on pages 24-31, DOI: 10.11646/zootaxa.4568.1.1, http://zenodo.org/record/259911
