Sun exposure and protection habits in transplant athletes: An international survey.

Photodermatol Photoimmunol Photomed 2021 Nov 24. Epub 2021 Nov 24.

Photobiological Dermatology Laboratory Medical Research Centre, Department of Dermatology and Medicine, University of Málaga, Málaga, Spain.

Background: Transplant recipients are particularly prone to the development of skin cancer, and overexposure to UV radiation during outdoor activities increases the risk of carcinogenesis.

Objective: The aim of this study was to analyze sun-related behaviors and knowledge in transplant athletes, examine the frequency of sunburns, and explore associations with a history of skin cancer.

Materials And Methods: Cross-sectional descriptive study. Participants (n=170) in the XXI World Transplant Games from >50 countries completed a questionnaire on sun protection habits and knowledge, type of transplant, immunosuppressive therapy, and personal history of skin cancer.

Results: The most common transplanted organs were the kidney (n=79), the liver (n=33), and the heart (n=31). Overall, 61.3% of athletes had been doing sport for >15 years and 79.5% spent >1-2 hours a day outdoors. Fifteen % of athletes had a history of skin cancer. The prevalence of sunburn in the previous year was 28.9%, higher in athletes aged <50 years (37.2%); without a primary school education (58.3%), not taking cyclosporin (32.6%) and athletes who played basketball (75%). The main sun protection measures used were sunscreen (68.9%) and sunglasses (67.3%). Use of a hat or cap was the only measure significantly associated with a reduced prevalence of sunburn.

Conclusions: Despite high awareness that sun exposure increases the risk of skin cancer, sunburn was common in transplant athletes. Efforts should be made to strengthen multidisciplinary sun protection education strategies and ensure periodic dermatologic follow-up to prevent sun-induced skin cancer in this population.

Sunscreens effectiveness are not altered by concomitant use of moisturizing creams: An ultraviolet reflectance photography study.

Photodermatol Photoimmunol Photomed 2021 Oct 21. Epub 2021 Oct 21.

Photobiological Dermatology Laboratory, Medical Research Center, Department of Dermatology and Medicine, Faculty of Medicine, University of Malaga, Málaga, Spain.

Background: Sunscreens are widely used to protect the skin against the harmful effects of solar radiation. It is not known whether solar protection factor of a sunscreen is altered by the concomitant use of other cosmetic products.

Objectives: The aim of this study was to analyze changes in the protective effect of different commercial and ISO standards sunscreens with high SPF applied shortly before and after application of non-sunscreens galenic formulas type moisturizing creams.

Methods: ISO 24444:2019 standard sunscreens, which claimed SPF 16 and 63, as well as 4 different claimed SPF 50 and 50+ commercial sunscreens were prepared and applied in different sequential order to the back of 25 volunteers and compared with different commercial moisturizing formulas. Ultraviolet (UV) reflectance photography followed by image analysis was used to compare untreated skin and skin treated with moisturizing creams alone and combined with sunscreens.

Results: The UV reflectance analysis showed no significant changes of the skin color reflectance treated with moisturizing cream compared with untreated skin. Application of the sunscreen formulations were associated with a 35% - 70% decrease in color related to the in vivo expected SPF, indicating significant UV absorption for all sunscreen formulas. All standard and commercial sunscreens showed no significant differences in UV reflection color level when combined with the different moisturizing creams applied before or after the sunscreen.

Conclusions: Effectiveness of low- and high-protection sunscreens were not altered by the concomitant use of a moisturizing creams applied shortly before and after the sunscreens.

Combined Mastectomy and Laparoscopic Hysterectomy with Salpingo-Oophorectomy in Transgender Men: a Cohort Study.

Reprod Sci 2021 12 5;28(12):3515-3518. Epub 2021 Oct 5.

Department of Gynecology and Obstetrics, Medical University of Graz, Auenbruggerplatz 14, 8036, Graz, Austria.

There are few data on complications with gender affirming surgery. The aim of this study was to assess peri- and postoperative complications of laparoscopic hysterectomy and mastectomy performed in a single sitting in transgender men. Assessment of intra- and postoperative complications in a series of 65 transgender men (mean age 27, range 18-47) undergoing concomitant mastectomy and laparoscopic hysterectomy with salpingo-oophorectomy. Mean operating time was 292 ± 47 min. Thirty-four (52%) patients experienced complications: 28 (41%) DINDO grade I, 0 DINDO grade 2, 6 (11%) DINDO grade III. The six grade 3 complications consisted of 5 hematomas requiring evacuation after mastectomy and 2 vaginal tears requiring transvaginal repair. Three patients were readmitted within 30 days, all for postoperative bleeding/hematoma. In transgender men, performing laparoscopic hysterectomy and mastectomy at a single sitting has a modest rate of perioperative complications, and may improve resource utilization.

Alternative ball-milling synthesis of vanadium-substituted polyoxometalates as catalysts for the aerobic cleavage of C-C and C-O bonds.

Dalton Trans 2021 Sep 28;50(37):12850-12859. Epub 2021 Sep 28.

Vanadium-substituted phosphomolybdic acids (H[PMoVO], denoted as V) are well-known oxidation catalysts that are generally prepared by the hydrothermal treatment of MoO and VO in the presence of HPO. This synthesis procedure is highly energy consuming and the V yields are not always acceptable. In the present work, an alternative hybrid mechanochemical/hydrothermal synthesis of V is proposed, comprising the ball-milling of MoO and VO, followed by a hydrothermal attack. The resulting materials, with 2 ≤ ≤ 3, obtained from this new route were compared, in terms of yield, energy consumption and catalytic activity, with a reference V sample prepared through a conventional hydrothermal treatment. The ball-milling step proved to lead not only to a shorter and far more energy-saving synthesis procedure, but also to high yields of V. Moreover, V from this alternative route proved to be generally more active than the conventionally prepared V in the aerobic oxidative cleavage of C-O and C-C bonds in 2-phenoxyacetophenone, used herein as a lignin model compound.
