Five decades of breeding populations census for 12 species of colonial waterbirds in northwestern Italy.

Colonial waterbirds, a major biodiversity element occurring in the core of ultra-anthropized Europe, are ideal indicators of the wellness of inland wetlands. Nonetheless, there is a critical knowledge gap in their trend and population status. We present an uninterrupted 47 years-long dataset of the breeding populations of 12 species of colonial waterbirds (Ardeidae, Phalacrocoracidae, Plataleidae, Threskiornitidae) throughout a 58,000 km2 agricultural region in the higher Po basin (NW Italy). A trained team of collaborators censused with standardized field techniques the number of nests of each species at 419 colonies in the 1972-2018 period, summing up a total of 236,316 records. Data cleaning and standardization were performed for each census year, ensuring robust and consistent data. This dataset is among the largest ever collected for a guild of European vertebrates. It has already been used to describe the factors influencing population trends, and still offers opportunities to explore a wide range of key ecological processes such as biological invasions, global change consequences and biodiversity impact of agricultural practices.

Effect of a short antibiotic treatment with roxithromycin on circulating adhesion molecules after coronary stenting: a single-center pilot trial.

BACKGROUND: The aim of this study was to assess the effect of periprocedural antibiotic treatment with roxithromycin on circulating cell adhesion molecules and restenosis after coronary stent implantation. METHODS: Case-control study enrolling 25 consecutive patients submitted to coronary stenting for stable, single-vessel coronary artery disease, treated with 300 mg roxithromycin once daily for 5 days, starting 2 days before the procedure (group R). Twenty-five patients, matched for lesion site, length and diameter, as control group (group C). The serological status for Chlamydia pneumoniae (CP) infection (IgG, ELISA) was assessed in all patients. The plasma concentrations of soluble intercellular adhesion molecule-1 (sICAM-1), E-selectin and C-reactive protein at 1 month after coronary stenting were compared with baseline values. Binary restenosis (> or = 50%) was also evaluated at 6 months. RESULTS: sICAM-1 significantly decreased at 1 month in group R vs group C (371 +/- 181 vs 573 +/- 273 ng/ml, p = 0.005). This decrease was more evident in patients with a positive serology for CP (CP+) (group R 373 +/- 131 vs group C 597 +/- 255 ng/ml, p = 0.014). Antibiotic treatment had no effects on circulating E-selectin levels at 1 month (56.7 +/- 97 vs 49.8 +/- 62 ng/ml, p = 0.54). The restenosis rate (9/50, 18%) was similar in the two groups (group R 5/25 [20%], group C 4/25 [16%]). The restenosis rate was similar in the CP+ vs CP- group (6/35 [17%] vs 3/15 [20%]). CONCLUSIONS: A short course of treatment with roxithromycin at the time of coronary stenting induces a significant reduction in the sICAM-1 levels at 1 month but apparently does not influence the restenosis rate.
