Habitat selection and diet of Western Capercaillie
P. 260-272Ecological features and conservation requirements of populations at the latitudinal limits
of a species’ geographical range frequently differ from those in other parts of the range.
Identifying such differences is key to implementing effective conservation strategies for
threatened range-edge populations especially, in the context of rapid global warming, at
the lower-latitude range edge. We studied habitat selection and diet of the endangered
Cantabrian Capercaillie Tetrao urogallus cantabricus in a recently discovered population
at the southernmost edge of the sub-species’ range. This is the only Western Capercaillie
population in the Mediterranean biogeographical region. We combined non-systematic
surveys based on questionnaires, reports and field sampling with data from radiotracking
to assess habitat selection. Diet was surveyed by micro-histological methods from droppings
collected in the new population, which inhabits Pyrenean Oak Quercus pyrenaica
forests and Scots Pine Pinus sylvestris plantations, and in two Cantabrian populations
inhabiting Eurosiberian forests. Capercaillie preferred large (> 500 ha) and medium-sized
(100–500 ha) Pyrenean Oak forest fragments and large Scots Pine plantations. Forest
fragments smaller than 100 ha and non-forested habitats were always avoided. Diet differed
markedly between Mediterranean and Eurosiberian populations. Bilberry Vaccinium
myrtillus is common in the diet of most Capercaillie populations but was scarce in the
study area and so was rare in the diet of the new population. Instead, Rockrose Halimium
lasianthum was described for the first time as a major food resource for the Capercaillie
and was consumed in autumn and winter. Pine needles were also heavily consumed in
winter. We document for the first time the strong preference of Capercaillie for Pyrenean
Oak forests and a moderately high consumption of the leaves, buds and acorns of this
tree species throughout the year. Habitat selection and diet of this Mediterranean
population differ from those of the core Cantabrian and other populations. Our results
suggest a wider environmental tolerance (phenotypic plasticity) in the species than previously
recognized. We advocate specific protection for this unique range-edge Capercaillie
population and its Pyrenean Oak forest habitatS
Cantabrian Capercaillie signs dissapeared after a wind farm construction
P. 65-74Capercaillie (Tetrao urogallus) is a grouse highly sensitive to human activities and declining throughout most of its European range. The Cantabrian subespecies Tetrao urogallus cantabricus is the most endangered and the only inhabiting caducifolious forests. Although many causes have been suggested as possible reasons for its alarming decline, no definite evidence supports any of them. Hence, the only effective measure so far is habitat conservation. In this sense, wind farms development is an emergent threat to this population. In a recently described Mediterranean habitat, we assessed Capercaillie occurrence before and after a wind farm construction in a wintering site. After construction Capercaillie presence signs decreased to zero and space use changed, likely due to human disturbances derived from the wind farm construction and maintenance. These changes in habitat use at a local scale and related negative effects on Capercaillie are discussed. As part of the precautionary principle conservation measures for this subespecies should avoid any wind farm within the current Cantabrian Capercaillie range while further research on Capercaillie and wind farms interactions should be urgently carried outN

La comparación entre dos cantaderos próximos y ubicados en la Reserva Nacional de Caza de Riaño (León), pone de manifiesto este hecho y señala su relación con las características topográficas de estos lugares de canto. De esta manera, se incluye una nueve manifestación en el comportamiento de la especie durante la época reproductoraN
Related Factors with Depression and Anxiety in Mastectomized Women Breast Cancer Survivors
Breast cancer (BC) is the most common cancer diagnosis with the highest mortality rate worldwide. The aim of this study was to identify factors related to depression and anxiety in mastectomized women BC survivors. A cross-sectional study was conducted with a sample of 198 women diagnosed with BC aged 30–80 years in Mexico. Depression and anxiety were assessed using the 14-item Hospital Anxiety and Depression Scale (HADS). The results showed that 94.44% and 69.18% of the women scored more than eight points on HADS in the anxiety and depression subscales, respectively; 70.20% and 10.60% were identified as pathological. The following variables were analyzed: age, time elapsed since the start of treatment, received treatment at the time of the evaluation, type of surgery, family history, marital status and employment status. Time elapsed since surgery, having a partner, and employment showed significant results as factors associated to levels of depression and anxiety in these patients. In conclusion, it has been shown that BCSs under 50 years of age receiving some kind of treatment, without family history, without a partner, with a job, with more than secondary education and with more than 5 years since diagnosis could have higher rates of clinical depression. On the other hand, BCSs older than 50 years receiving some kind of treatment, without family history, without a partner, with a job, with more than secondary education and with more than 5 years since diagnosis, could have higher rates of clinical anxiety. In conclusion, the variables studied provide valuable information for the implementation of psychotherapy plans in healthcare systems to reduce the risk of depression and/or anxiety in women with BC who have undergone mastectomy

COVID-19 in hospitalized HIV-positive and HIV-negative patients : A matched study
CatedresObjectives: We compared the characteristics and clinical outcomes of hospitalized individuals with COVID-19 with [people with HIV (PWH)] and without (non-PWH) HIV co-infection in Spain during the first wave of the pandemic. Methods: This was a retrospective matched cohort study. People with HIV were identified by reviewing clinical records and laboratory registries of 10 922 patients in active-follow-up within the Spanish HIV Research Network (CoRIS) up to 30 June 2020. Each hospitalized PWH was matched with five non-PWH of the same age and sex randomly selected from COVID-19@Spain, a multicentre cohort of 4035 patients hospitalized with confirmed COVID-19. The main outcome was all-cause in-hospital mortality. Results: Forty-five PWH with PCR-confirmed COVID-19 were identified in CoRIS, 21 of whom were hospitalized. A total of 105 age/sex-matched controls were selected from the COVID-19@Spain cohort. The median age in both groups was 53 (Q1-Q3, 46-56) years, and 90.5% were men. In PWH, 19.1% were injecting drug users, 95.2% were on antiretroviral therapy, 94.4% had HIV-RNA < 50 copies/mL, and the median (Q1-Q3) CD4 count was 595 (349-798) cells/μL. No statistically significant differences were found between PWH and non-PWH in number of comorbidities, presenting signs and symptoms, laboratory parameters, radiology findings and severity scores on admission. Corticosteroids were administered to 33.3% and 27.4% of PWH and non-PWH, respectively (P = 0.580). Deaths during admission were documented in two (9.5%) PWH and 12 (11.4%) non-PWH (P = 0.800). Conclusions: Our findings suggest that well-controlled HIV infection does not modify the clinical presentation or worsen clinical outcomes of COVID-19 hospitalization
How do women living with HIV experience menopause? Menopausal symptoms, anxiety and depression according to reproductive age in a multicenter cohort
CatedresBackground: To estimate the prevalence and severity of menopausal symptoms and anxiety/depression and to assess the differences according to menopausal status among women living with HIV aged 45-60 years from the cohort of Spanish HIV/AIDS Research Network (CoRIS). Methods: Women were interviewed by phone between September 2017 and December 2018 to determine whether they had experienced menopausal symptoms and anxiety/depression. The Menopause Rating Scale was used to evaluate the prevalence and severity of symptoms related to menopause in three subscales: somatic, psychologic and urogenital; and the 4-item Patient Health Questionnaire was used for anxiety/depression. Logistic regression models were used to estimate odds ratios (ORs) of association between menopausal status, and other potential risk factors, the presence and severity of somatic, psychological and urogenital symptoms and of anxiety/depression. Results: Of 251 women included, 137 (54.6%) were post-, 70 (27.9%) peri- and 44 (17.5%) pre-menopausal, respectively. Median age of onset menopause was 48 years (IQR 45-50). The proportions of pre-, peri- and post-menopausal women who had experienced any menopausal symptoms were 45.5%, 60.0% and 66.4%, respectively. Both peri- and post-menopause were associated with a higher likelihood of having somatic symptoms (aOR 3.01; 95% CI 1.38-6.55 and 2.63; 1.44-4.81, respectively), while post-menopause increased the likelihood of having psychological (2.16; 1.13-4.14) and urogenital symptoms (2.54; 1.42-4.85). By other hand, post-menopausal women had a statistically significant five-fold increase in the likelihood of presenting severe urogenital symptoms than pre-menopausal women (4.90; 1.74-13.84). No significant differences by menopausal status were found for anxiety/depression. Joint/muscle problems, exhaustion and sleeping disorders were the most commonly reported symptoms among all women. Differences in the prevalences of vaginal dryness (p = 0.002), joint/muscle complaints (p = 0.032), and sweating/flush (p = 0.032) were found among the three groups. Conclusions: Women living with HIV experienced a wide variety of menopausal symptoms, some of them initiated before women had any menstrual irregularity. We found a higher likelihood of somatic symptoms in peri- and post-menopausal women, while a higher likelihood of psychological and urogenital symptoms was found in post-menopausal women. Most somatic symptoms were of low or moderate severity, probably due to the good clinical and immunological situation of these women
