Geographical shifts in the successional dynamics of inland dune shrub communities.

Species' environmental requirements and large-scale spatial and evolutionary processes determine the structure and composition of local communities. However, ecological interactions also have major effects on community assembly at landscape and local scales. We evaluate whether two xerophytic shrub communities occurring in SW Portugal follow constrained ecological assembly dynamics throughout large geographical extents, or their composition is rather driven by species' individualistic responses to environmental and macroecological constraints.

Differential Impact of the Pinewood Nematode on Species Under Drought Conditions.

The pinewood nematode (PWN), , responsible for the pine wilt disease (PWD), is a major threat to pine forests worldwide. Since forest mortality due to PWN might be exacerbated by climate, the concerns regarding PWD in the Mediterranean region are further emphasized by the projected scenarios of more drought events and higher temperatures. In this context, it is essential to better understand the pine species vulnerability to PWN under these conditions.

Materials & Methods: Based on a retrospective study over 11.

Dermatoscopic and clinical features of congenital or congenital-type nail matrix nevi: A multicenter prospective cohort study by the International Dermoscopy Society.

Background: Congenital nail matrix nevi (NMN) are difficult to diagnose because they feature clinical characteristics suggestive of adult subungual melanoma. Nail matrix biopsy is difficult to perform, especially in children.

Objective: To describe the initial clinical and dermatoscopic features of NMN appearing at birth (congenital) or after birth but before the age of 5 years (congenital-type).

Guidelines for clinical trials of frontal fibrosing alopecia: consensus recommendations from the International FFA Cooperative Group (IFFACG).

Background: Frontal fibrosing alopecia (FFA) has become one of the most common causes of cicatricial alopecia worldwide. However, there is a lack of clear aetiology and robust clinical trial evidence for the efficacy and safety of agents currently used for treatment.

Objectives: To enable data to be collected worldwide on FFA using common criteria and assessment methods.

Potential of Solar UV Radiation for Inactivation of Coronaviridae Family Estimated from Satellite Data.

The pandemic COVID-19 disease affects people dramatically overall the globe by illness and death. Several strategies are applied to restrict the spread of this disease such as lockdown, adequate social distance in different activities, hand disinfection and the use of masks. Potential hazard outdoors comes from released viruses, which may remain in the air for a while and settle down afterward and contaminating surfaces.

CO laser treatment of a kissing nevus of the penis: an alternative solution for a rare condition.

Divided or kissing nevi are a rare clinical variant of congenital melanocytic nevi developing in adjacent areas of the skin that undergo cleavage during embryogenesis. Penile lesions are even rarer, with only few cases described in the literature. Typically, they present as two opposing dark colored macular or papular lesions on the glans and prepuce, exhibiting a mirror-image symmetry relative to the coronal sulcus.

Estimation of the Allergenic Potential of Urban Trees and Urban Parks: Towards the Healthy Design of Urban Green Spaces of the Future.

The impact of allergens emitted by urban green spaces on health is one of the main disservices of ecosystems. The objective of this work is to establish the potential allergenic value of some tree species in urban environments, so that the allergenicity of green spaces can be estimated through application of the Index of Urban Green Zones Allergenicity (I). Multiple types of green spaces in Mediterranean cities were selected for the estimation of I.

Prevalence and determinants of sunbed use in thirty European countries: data from the Euromelanoma skin cancer prevention campaign.

Background: Although considered as a first-group carcinogen, indoor tanning is a common practice in Europe. Euromelanoma is a pan-European skin cancer prevention campaign.

Objectives: To compare several European countries in terms of the prevalence and determinants of sunbed use.

Sunbed use legislation in Europe: assessment of current status.

Background: The use of UV-emitting tanning devices for cosmetic purposes is associated with an increased risk of melanoma and non-melanoma skin cancer. Young women are the most frequent users, therefore, there is an increasing concern about the regulation of sunbed use.

Objective: The primary objective is to assess the current legislation on sunbed use among European countries.

Association of sunbed use with skin cancer risk factors in Europe: an investigation within the Euromelanoma skin cancer prevention campaign.

Introduction: Sunbed use has been significantly associated with increased risk of melanoma and non-melanoma skin cancer (NMSC), but its relationship with melanoma's risk factors such as high nevus count, atypical nevi and lentigines is poorly studied. Euromelanoma is a skin cancer prevention campaign conducted all over Europe. It offers a once-a-year screening during which participants' data, including sunbed use and phenotype, are collected via questionnaires.

Sun protection behaviour and skin cancer literacy among outdoor runners.

Outdoor runners have an increased risk of melanoma and non-melanoma skin cancer. The purpose of this study was to assess skin cancer literacy and sun exposure and protection behaviour among outdoor runners during training. A cross-sectional survey-based study was conducted.

Local topographic and edaphic factors largely predict shrub encroachment in Mediterranean drylands.

Shrub encroachment influences several ecosystem services in drylands worldwide. Yet, commonly used strategies to reduce encroachment show a low medium-term success, calling for a better understanding of its causes. Previous works identified multiple drivers responsible for this phenomenon, including anthropogenic and environmental causes.

Risk factors for development of new skin neoplasms in patients with past history of skin cancer: A survival analysis.

We conducted a retrospective study aiming to assess the risk, and associated risk factors, of developing subsequent skin cancers after having a first diagnosis of skin cancer. We included all patients with biopsy-proven skin cancer attending a dermatology clinic between July 2007 and July 2017. We assessed the frequency of new skin cancers, as well as potential demographic and clinical factors significantly associated with occurrence of such neoplasms, that were identified by means of a survival analysis.
