▲Clinical, biometric and ultrasound assessment of the effects of daily use of a nutraceutical composed of lycopene, acerola extract, grape seed extract and Biomarine Complex in photoaged human skin * Avaliações clínica, biométrica e ultrassonográfica dos efeitos do uso diário de um nutracêutico a base de licopeno, extrato de acerola, extrato de semente de uva e Complexo Biomarinho na pele fotoenvelhecida humana Abstract: BACKGROUND: The use of nutraceuticals has become frequent in the cutaneous approach to photoaging. OBJECTIVES: To assess the clinical efficacy of a nutraceutical product composed of lycopene, acerola extract, grape seed extract and Biomarine ComplexT in photoaged human skin. METHODS: 50 women, from 35 to 60 years of age, phototypes I to III, were assessed. For 120 days, they associated the nutraceutical product with the use of a sunscreen FPS15. On days 0 (D0), 30 (D30), 60 (D60), 90 (D90) and 120 (D120) they were evaluated and underwent Medical Assessments and Self-Assessment and cutaneous biometric analyses (corneometry, sebumetry and pH-metry) in the skin of the left zygomatic region and the upper medial side region of the left arm; on days 0 (D0), 30 (D30) and 120 (D120) the skin of the same regions was analyzed by ultrasound. On days 0 (D0) and 120 (D120) skin biopsies were performed in the areas where instrumental evaluation was performed (to evaluate collagen and elastic fibers). RESULTS: There was an improvement of the general status of the skin of all volunteers by the Medical and Volunteer Self-Assessments; increased parameters of cutaneous hydration, reduction of pH, increasing of ultrasound density and a histological increment of collagen and elastic fibers (both on the face and arm); there was a reduction of seborrhea (only on the face) CONCLUSIONS: The daily use of a nutraceutical product containing lycopene, acerola extract, grape seed extract and Biomarine ComplexT showed an important adjuvant effect to counteract skin photoaging.

OBJETIVOS: Avaliar a eficácia clínica do uso de um produto nutracêutico a base de licopeno, extrato de acerola, extrato de semente de uva e Complexo BiomarinhoT na pele fotoenvelhecida humana. MÉTODOS: Foram avaliadas 50 mulheres, de 35 a 60 anos de idade, fototipo I a III. Por 120 dias, elas associaram ao uso de fotoprotetor FPS15 a tomada diária do produto nutracêutico em questão. Nos dias 0 (D0), 30 (D30), 60 (D60), 90 (D90) e 120 (D120) elas foram avaliadas, quando sofreram Avaliações Médica e Auto-Avaliação e análises biométricas cutâneas (corneometria, sebumetria e pHmetria) nas peles da região zigomática esquerda e face súpero-medial do braço esquerdos; nos dias 0 (D0), 30 (D30) e 120 (D120) a pele das mesmas regiões foram analisadas do ponto de vista ultrassonográfico. Nos dias 0 (D0) e 120 (D120) biópsias cutâneas foram realizadas nas respectivas áreas das análises inst...

ARTIGO ORIGINAL ResumoContexto: Dentre as maiores causas de internamento hospitalar em pacientes com diabetes melito tipos 1 e 2 estão as complicações do pé diabético, principalmente pelas sequelas, muitas vezes incapacitantes, destacando-se as amputações de membros inferiores. A insuficiência vascular periférica ocorre mais precocemente nesses pacientes. A coexistência de neuropatia, isquemia e imunodeficiência favorece o desenvolvimento de infecções nos membros inferiores, que, se não tratadas adequadamente, podem levar a amputações e até à morte.Objetivos: Comparar os fatores de risco para amputações maiores e menores em pacientes diabéticos de um Programa de Saúde da Família do CAIC Virgem dos Pobres III, em Maceió, AL. Métodos:Foram examinados 93 pacientes com o diagnóstico de diabetes melito, sendo avaliada a realização ou não de amputações de membros inferiores. As variáveis analisadas foram: sexo, idade, tipo do diabetes, pressão arterial, amputação prévia (se maior ou menor), alterações dermatológicas, alterações de pulsos arteriais pedioso e tibial posterior, deformidades e neuropatia, e foram classificadas de acordo com a classificação de Wagner e de Texas.Resultados: Todos os pacientes eram diabéticos tipo 2. Verificou-se que 4,30% dos pacientes evoluíram para amputação de membros inferiores. Não se observou variação significativa da hipertensão, deformidades e neuropatia em relação ao grupo de pacientes que foram amputados. Entretanto, a ausência de detecção dos pulsos distais dos membros inferiores revelou-se bastante significativa com relação ao desfecho de amputação. Conclusão:Deve-se proporcionar aos diabéticos um atendimento ambulatorial adequado para que seja possível prevenir ou minimizar tais complicações.Palavras-chave: Amputação, pé diabético, diabetes melito. AbstractBackground: The main causes of hospital admission in patients with type 1 and 2 diabetes mellitus include diabetic foot complications, which may result in particularly disabling sequelae, such as lower limb amputation. Peripheral vascular insufficiency is a common early occurrence in these patients. The coexistence of neuropathy, ischemia, and immunodeficiency favors the development of infections in the lower limbs, which if not treated properly can lead to amputation and even death.

BackgroundSkin aging is a natural process that may be aggravated by environmental factors. Topical products are the conventional means to combat aging; however, the use of oral supplements is on the rise to assist in the management of aged skin.ObjectiveThe purpose of this study was to assess the effects and safety of an oral supplement containing (per tablet) marine protein (105 mg), vitamin C (27 mg), grape seed extract (13.75 mg), zinc (2 mg), and tomato extract (14.38 mg) in the improvement of skin aging in men.MethodsThis single-center, open-label, quasi-experimental clinical study enrolled 47 male subjects, aged 30–45 years, with phototypes I–IV on the Fitzpatrick scale. Subjects received two tablets of the oral supplement for 180 consecutive days. Each subject served as their own control. Clinical assessments were made by medical personnel and by the subjects, respectively. Objective assessments were carried out through pH measurements, sebumetry, corneometry, ultrasound scanning, skin biopsies, and photographic images.ResultsForty-one subjects (87%) completed the study. Clinical improvements on both investigator- and subject-rated outcomes were found for the following parameters: erythema, hydration, radiance, and overall appearance (P<0.05). The objective measurements in the facial skin showed significant improvements from baseline in skin hydration (P<0.05), dermal ultrasound density (P<0.001), and reduction of skin pH (P<0.05). No statistical improvement in relation to sebum was found. The photographic assessment showed an improvement in the overall appearance. The results of the objective measurements were found to be correlated with the subjects’ satisfaction by an increase of collagen and elastic fibers.ConclusionThe use of an oral supplement based on a unique biomarine complex, vitamin C, grape seed extract, zinc, and tomato extract produced improvements in the signs of skin aging in men.

The study included 30 female volunteers between 30 and 60 years old, with wrinkles of scores 3 and 4, according to the wrinkle severity rating scale, phototypes I to V, healthy skin in the facial area and free
