Estratégias fotoprotetoras contra fotocarcinogênese e fotoenvelhecimento

The sunlight is not only indispensable to life and physiological processes, but it is also associated with the development of photoaging and, in some more severe cases, with photocarcinogenesis in genetically prone and vulnerable phototype populations in a proportional exposure/risk ratio. Considering the different methods of solar protection, especially the various formulations of organic and inorganic sunscreens, the present study aimed to review the best protective strategy against the damaging effects of the sun rays, enabling the sustainable promotion of health and quality of life. We have concluded that the use of clothing protecting agents associated with sunscreens of wide spectrum—those that combine inorganic/barrier compounds with organic/filtering agents—results in the most efficient solar protection combination, by associating a higher degree of UVA and UVB waves protection with high photostability and water stability to subjects under sustained sun exposure, especially those who work under these conditions

Avaliação dos níveis de ferritina e vitamina B12 em pacientes submetidos à cirurgia bariátrica suplementados com polivitamínico

The nutritional deficiencies of iron and vitamin B12 are the major changes that endanger the success of bariatric surgery. The objective of this study was to evaluate ferritin and vitamin B12 levels in patients with Grade III obesity of the Brazilian Unified Health System (SUS), who underwent Roux-en-Y gastrojejunal shunting (BPGYR) supplemented free of charge with the Materna® product his multivitamin was distributed to 40 patients free of charge for 24 months and 23 patients, the control group, did not receive the drug. The comparison of ferritin and vitamin B12 in patients submitted to BPGYR, with free supplementation were superior to those observed for the control group. It is concluded that the free supply of Materna® by SUS to patients submitted to BPGYR is a recommended measure for adequate control and adherence of the patient to the treatment
