Article Abstract
To explore whether season is a risk factor of periprosthetic joint infection (PJI) after total joint arthroplasty (TJA) and explain it with the theory of traditional Chinese medicine. This was a retrospective cohort study. Only patients who suffered from PJI within 1 month after TJA were included in the study. Occurrence of PJI was the outcome of this study. Chi-squared test and t test was used to assess differences for baseline characteristics. Chi-square test was used to analyze whether season was related to the occurrence of PJI. Logistic regression was used to evaluate the association between season and occurrence of PJI. The incidence of PJI in summer is significantly higher than that in winter, whether after total knee arthroplasty (Chi-square value = 6.455, P = .011) or total hip arthroplasty (Chi-square value = 6.141, P = .013). Summer was an independent risk factor for PJI (OR = 4.373, 95% confidence interval = 1.899-10.673, P = .004). To be more exact, compared to nonlate summer (19.51%), and PJI is mainly concentrated in late summer (80.49%). Late summer was an independent risk factor of PJI after TJA. The infection rate of PJI after TJA in late summer is higher than other seasons. A more thorough preoperative disinfection procedure is needed in late summer.

Snow is an important insulator of Arctic soils during winter and may be a source of soil moisture in summer. Changes in snow depth are likely to affect fine root growth and mortality via changes in soil temperature, moisture, and/or nutrient availability, which could alter aboveground growth and reproduction of Arctic vegetation. We explored fine root dynamics at three contrasting treelines in northwest Alaska.

Many Arctic fishes experience prolonged periods of extreme cold and large thermal variation over both rapid and seasonal time scales which challenge critical physiological functions. In the central Canadian Arctic, we caught wild adult lake trout (Salvelinus namaycush) acclimatized to winter and summer temperatures to determine the extent to which they seasonally adjust cardiac thermal performance and adrenergic control. We assessed the intrinsic and maximum heart rate (f and f) of anaesthetised fish through cholinergic blockade and either adrenergic blockade (f) or stimulation (f) during acute warming.

is a key picocyanobacterium in coastal ecosystems, yet its seasonal bloom dynamics and environmental responses remain unclear in temperate coastal seas. Here, we integrated flow cytometry and gene analysis to investigate its bloom development and community succession in Laizhou Bay, based on 3 years of 10 seasonal surveys and a year-long monthly observation at a fixed station. blooms reached their peak in summer (up to 10 cells mL), particularly in the southern part of the bay, with high abundances in autumn as well.

Stemflow, the concentrated fraction of rainfall that drains down tree trunks, can translocate canopy biota to the forest floor, but its eukaryotic composition remains uncharacterized via eDNA methods. We collected stemflow from 18 Fagus grandifolia (American beech) trees during ten storms in northeastern Ohio (USA) and analyzed 18S rRNA eDNA to resolve transported microbial-eukaryote communities. Over 12 million reads (83 samples) revealed 920 zero-radius OTUs spanning fungi, algae, protists, and metazoans.

Background: Pathogenic blood-feeding nematodes, such as Haemonchus contortus and the invasive Ashworthius sidemi, infect a wide range of wild and domestic ruminants. While the spread of A. sidemi among European cervids has been studied, its presence in chamois (Rupicapra rupicapra) remains poorly documented.
