Recent distribution of Red-legged Partridge Alectoris rufa in Piedmont (North Western Italy): signs of recent spreading.
The red-legged partridge Alectoris rufa in Piedmont (NW Italy) is historically limited to the hilly and low-mountain areas of
the southern half of the region, in particular lying in the Langhe and the Apennines on the Ligurian border, in the districts of Cuneo, Asti
and Alessandria. In the Cuneo district, on the Maritime Alps, hybrid populations with Alectoris graeca were also known. The distribution
of the species has been mapped in some occasions with the \u201cAtlases\u201d projects of the GPSO (Gruppo Piemontese Studi Ornitologici) and
special enquiries. On this occasion we tried to update the geographical distribution of the species using data conferred by bird-watchers
on www.regione.piemonte.it/aves/, managed by the GPSO, enquiries among hunters\u2019 organizations and specific field researches. The resulting
distribution is shown on a 10 km square grid. The species shows signs of distribution dynamism, with the occupation of some lowland
areas, where it was totally absent until the \u201890s. A little range expansion is noticeable also in the Western Monferrato. The situation
seems to be more stable (or even declining) in the Langhe area and the species is now disappeared from the alpine border. In general we
are seeing an areal contraction or density reduction on hills and mountains and an extension on lowlands. The observed changes seem to
be attributable mainly to environmental and climate changes
A multidisciplinary approach to estimating wolf population size for long-term conservation
The wolf (Canis lupus) is among the most controversial of wildlife species. Abundance estimates are required to inform public debate and policy decisions, but obtaining them at biologically relevant scales is challenging. We developed a system for comprehensive population estimation across the Italian alpine region (100,000 km2), involving 1513 trained operators representing 160 institutions. This extensive network allowed for coordinated genetic sample collection and landscape-level spatial capture–recapture analyses that transcended administrative boundaries to produce the first estimates of key parameters for wolf population status assessment. Wolf abundance was estimated at 952 individuals (95% credible interval 816–1120) and 135 reproductive units (i.e., packs) (95% credible interval 112–165). We also estimated that mature individuals accounted for 33–45% of the entire population. The monitoring effort was spatially estimated thereby overcoming an important limitation of citizen science data. This is an important approach for promoting wolf–human coexistence based on wolf abundance monitoring and an endorsement of large-scale harmonized conservation practices
Association of kidney disease measures with risk of renal function worsening in patients with type 1 diabetes
Background: Albuminuria has been classically considered a marker of kidney damage progression in diabetic patients and it is routinely assessed to monitor kidney function. However, the role of a mild GFR reduction on the development of stage 653 CKD has been less explored in type 1 diabetes mellitus (T1DM) patients. Aim of the present study was to evaluate the prognostic role of kidney disease measures, namely albuminuria and reduced GFR, on the development of stage 653 CKD in a large cohort of patients affected by T1DM. Methods: A total of 4284 patients affected by T1DM followed-up at 76 diabetes centers participating to the Italian Association of Clinical Diabetologists (Associazione Medici Diabetologi, AMD) initiative constitutes the study population. Urinary albumin excretion (ACR) and estimated GFR (eGFR) were retrieved and analyzed. The incidence of stage 653 CKD (eGFR < 60 mL/min/1.73 m2) or eGFR reduction > 30% from baseline was evaluated. Results: The mean estimated GFR was 98 \ub1 17 mL/min/1.73m2 and the proportion of patients with albuminuria was 15.3% (n = 654) at baseline. About 8% (n = 337) of patients developed one of the two renal endpoints during the 4-year follow-up period. Age, albuminuria (micro or macro) and baseline eGFR < 90 ml/min/m2 were independent risk factors for stage 653 CKD and renal function worsening. When compared to patients with eGFR > 90 ml/min/1.73m2 and normoalbuminuria, those with albuminuria at baseline had a 1.69 greater risk of reaching stage 3 CKD, while patients with mild eGFR reduction (i.e. eGFR between 90 and 60 mL/min/1.73 m2) show a 3.81 greater risk that rose to 8.24 for those patients with albuminuria and mild eGFR reduction at baseline. Conclusions: Albuminuria and eGFR reduction represent independent risk factors for incident stage 653 CKD in T1DM patients. The simultaneous occurrence of reduced eGFR and albuminuria have a synergistic effect on renal function worsening

A multidisciplinary approach to estimating wolf population size for long-term conservation
The wolf (Canis lupus) is among the most controversial of wildlife species. Abundance estimates are required to inform public debate and policy decisions, but obtaining them at biologically relevant scales is challenging. We developed a system for comprehensive population estimation across the Italian Alpine Region (100,000 km2 ), involving 1,513 trained operators representing 160 institutions. This extensive network allowed for coordinated genetic sample collection and landscape-level spatial capture-recapture analysis transcending administrative boundaries. We produced the first estimates of key parameters for wolf population status assessment including wolf abundance (952 individuals, 95% CrI: 816-1120), the number of reproductive units (135 packs, 95% CrI: 112-165), and the proportion of mature individuals (33-45%). The results also provided reliable information about the monitoring effort, thereby overcoming an important limitation of citizen-science data. This is an effective approach for promoting wolf-human coexistence based on wolf abundance monitoring, and a tool for endorsing large-scale harmonized conservation practice

Low incidence of SARS-CoV-2, risk factors of mortality and the course of illness in the French national cohort of dialysis patients
International audienceThe aim of this study was to estimate the incidence of COVID-19 disease in the French national population of dialysis patients, their course of illness and to identify the risk factors associated with mortality. Our study included all patients on dialysis recorded in the French REIN Registry in April 2020. Clinical characteristics at last follow-up and the evolution of COVID-19 illness severity over time were recorded for diagnosed cases (either suspicious clinical symptoms, characteristic signs on the chest scan or a positive reverse transcription polymerase chain reaction) for SARS-CoV-2. A total of 1,621 infected patients were reported on the REIN registry from March 16th, 2020 to May 4th, 2020. Of these, 344 died. The prevalence of COVID-19 patients varied from less than 1% to 10% between regions. The probability of being a case was higher in males, patients with diabetes, those in need of assistance for transfer or treated at a self-care unit. Dialysis at home was associated with a lower probability of being infected as was being a smoker, a former smoker, having an active malignancy, or peripheral vascular disease. Mortality in diagnosed cases (21%) was associated with the same causes as in the general population. Higher age, hypoalbuminemia and the presence of an ischemic heart disease were statistically independently associated with a higher risk of death. Being treated at a selfcare unit was associated with a lower risk. Thus, our study showed a relatively low frequency of COVID-19 among dialysis patients contrary to what might have been assumed
