Objectives: Dysbiosis of the skin microbiota has been identified as a key factor in the development of acne. This study was aimed to evaluate the effect of a facial cream gel containing a biotechnological phytocomplex, niacinamide and succinic acid on the bacterial diversity of subjects with mild-moderate acne and its clinical benefits due to microbiota changes.

Methods: Open-label, clinical study in 44 subjects with mild-moderate acne treated with a facial cream gel for 8 weeks.

Background: The disruption of the microbial community or dysbiosis alters the functional composition, metabolic activity, and local distribution of the microbiota leading the development of acne. The aim of this study is to evaluate the effect of a lotion containing a biotechnological phytocomplex, niacinamide, and succinic acid in the bacterial diversity of subjects with truncal mild-moderate acne and its clinical benefits due to microbiota changes.

Materials And Methods: Open, clinical study in 43 subjects with truncal mild-moderate acne treated with a lotion for 8 weeks.

Background: A new water-soluble formulation with ciclopirox has shown a higher penetration than other ciclopirox nail lacquers currently marketed, thus providing a higher concentration of ciclopirox into the nail.

Objective: To evaluate the efficacy and safety of a new ciclopirox nail hydrolacquer compared with its vehicle and an active comparator (hydroxypropyl chitosan-based 80 mg/g ciclopirox nail lacquer) for the treatment of toenail fungal infection.

Methods: Phase III, multicenter, randomised, double-blind, clinical trial in patients with distal mild to moderate toenail onychomycosis due to dermatophyte fungi.

Darier-White disease is a relatively common autosomal dominant genodermatosis caused by mutation in the ATP2A2 gene. It is characterized by multiple warty papules coalescing into plaques in the seborrheic areas and by specific histological skin changes. Palm and sole involvement in Darier-White disease is usually mild, mainly featuring discrete and small keratotic papules.

Background: Although the clinical hair changes that occur under treatment with epidermal growth factor receptor inhibitors (EGFRIs) are documented, their trichoscopic features have not been reported.

Objective: To evaluate the trichoscopic findings in scalp and facial hair, induced by EGFRI treatment.

Methods: Patients treated with EGFRIs at a tertiary oncodermatology clinic in 2015 through 2017 were evaluated for macroscopic and trichoscopic changes.

Introduction: The design of training programs for football players is not straightforward due to intra- and inter-individual variability that leads to different physiological responses under similar training loads.

Objective: To study the association between the external load, defined by variables obtained using electronic performance tracking systems (EPTS), and the urinary metabolome as a surrogate of the metabolic adaptation to training.

Methods: Urine metabolic and EPTS data from 80 professional football players collected in an observational longitudinal study were analyzed by ultra-performance liquid chromatography coupled to electrospray ionization quadrupole time-of-flight mass spectrometry and assessed by partial least squares (PLS) regression.

Introduction: Will-to-live, a central concept in well-being theories, represents a positive attitudinal component towards one's own life. It has been identified as a mediator between the self-perception of aging and longevity and health. The objective of this study is to characterise elderly people with high levels of will-to-live in the main dimensions of positive psychology.

Energy sensing is indispensable to balance anabolic and catabolic processes for the maintenance of cell viability. Pancreatic β cells are especially relevant because of their involvement in the coordination of insulin secretion when glucose concentration arises in the local milieu. In this work, we uncover the increased susceptibility of pancreatic β cells to cell death in response to different energy stressors.

Background: In the present study, we explored potential protein biomarkers useful to predict the therapeutic response of knee osteoarthritis (KOA) patients treated with pharmaceutical grade Chondroitin sulfate/Glucosamine hydrochloride (CS+GH; Droglican, Bioiberica), in order to optimize therapeutic outcomes.

Methods: A shotgun proteomic analysis by iTRAQ labelling and liquid chromatography-mass spectrometry (LC-MS/MS) was performed using sera from 40 patients enrolled in the Multicentre Osteoarthritis interVEntion trial with Sysadoa (MOVES). The panel of proteins potentially useful to predict KOA patient's response was clinically validated in the whole MOVES cohort at baseline ( = 506) using commercially available enzyme-linked immunosorbent assays kits.

The present study was designed to investigate the functional status of β2 adrenoceptors (β2AR) in two models of chronic inflammatory disease: liver cirrhosis (LC) and osteoarthritis (OA). The β2AR gene contains three single nucleotide polymorphisms at amino acid positions 16, 27 and 164. The aim of the present study was to investigate the potential influence of lymphocyte β2AR receptor functionality and genotype in LC and OA patients.

Objective: The aim of this study was to develop a genetic prognostic tool to predict radiographic progression towards severe disease in primary knee OA (KOA) patients.

Methods: This investigation was a cross-sectional, retrospective, multicentric association study in 595 Spanish KOA patients. Caucasian patients aged ≥40 years at the time of diagnosis of primary KOA of Kellgren-Lawrence grade 2 or 3 were included.

Patients with severe biotinidase deficiency (BD), if untreated, may exhibit seizures, psychomotor delay, deafness, ataxia, visual pathology, conjunctivitis, alopecia, and dermatitis. Clinical features normally appear within the first months of life, between two and five. Seizures are one of the most common symptoms in these patients (55%), usually presented as generalized tonic-clonic, and improving within 24 h of biotin treatment.

Background: Lymphoedema is a common and troublesome condition that develops following breast cancer treatment. The aim of this study is to analyze the effectiveness of Manual Lymphatic Drainage in the treatment of postmastectomy lymphoedema in order to reduce the volume of lymphoedema and evaluate the improvement of the concomitant symptomatology.

Methods: A randomized, controlled clinical trial in 58 women with post-mastectomy lymphoedema.
