Abstract
The development of minimally invasive, non-surgical, and office-based procedures that have minimal downtime has stimulated an interest among men who may seek cosmetic treatments to increase competitiveness and appear youthful in the workplace. There has also been greater media attention on the male appearance and grooming along with increasing acceptance of cosmetic procedures within society. Achieving a successful cosmetic treatment in a male patient requires the physician to recognize the gender differences that exist. These include anatomy, skin aging, and skin biology, as well as behavioral patterns that exist in this population.

Li H, Cui F, Wang T, Wang W, Zhang D. The impact of sunlight exposure on brain structural markers in the UK Biobank. Sci Rep 2024; 14:10313. [PMID: 38705875 PMCID: PMC11070413 DOI: 10.1038/s41598-024-59633-z] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/13/2024] [Accepted: 04/12/2024] [Indexed: 05/07/2024] Open
Abstract
Sunlight is closely intertwined with daily life. It remains unclear whether there are associations between sunlight exposure and brain structural markers. General linear regression analysis was used to compare the differences in brain structural markers among different sunlight exposure time groups. Stratification analyses were performed based on sex, age, and diseases (hypertension, stroke, diabetes). Restricted cubic spline was performed to examine the dose-response relationship between natural sunlight exposure and brain structural markers, with further stratification by season. A negative association of sunlight exposure time with brain structural markers was found in the upper tertile compared to the lower tertile. Prolonged natural sunlight exposure was associated with the volumes of total brain (β: - 0.051, P < 0.001), white matter (β: - 0.031, P = 0.023), gray matter (β: - 0.067, P < 0.001), and white matter hyperintensities (β: 0.059, P < 0.001). These associations were more pronounced in males and individuals under the age of 60. The results of the restricted cubic spline analysis showed a nonlinear relationship between sunlight exposure and brain structural markers, with the direction changing around 2 h of sunlight exposure. This study demonstrates that prolonged exposure to natural sunlight is associated with brain structural markers change.

INTERNATIONAL JOURNAL OF ENVIRONMENTAL RESEARCH AND PUBLIC HEALTH 2022; 19:ijerph19031742.

Abstract
Intermittent sun exposure is the major environmental risk factor for cutaneous melanoma (CM). Cumulative sun exposure and other environmental agents, such as environmental arsenic exposure, have not shown consistent associations. Ambient ultraviolet radiation (UVR) was used to measure individual total sun exposure as this is thought to be less prone to misclassification and recall bias. Data were analyzed from 1096 CM cases and 1033 controls in the Iowa Study of Skin Cancer and Its Causes, a population-based, case-control study. Self-reported residential histories were linked to satellite-derived ambient UVR, spatially derived environmental soil arsenic concentration, and drinking water arsenic concentrations. In men and women, ambient UVR during childhood and adolescence was not associated with CM but was positively associated during adulthood. Lifetime ambient UVR was positively associated with CM in men (OR for highest vs. lowest quartile: 6.09, 95% confidence interval (CI) 2.21–16.8), but this association was not as strong among women (OR for highest vs. lowest quartile: 2.15, 95% CI 0.84–5.54). No association was detected for environmental soil or drinking water arsenic concentrations and CM. Our findings suggest that lifetime and adulthood sun exposures may be important risk factors for CM.

Combinations of peptides synergistically activate the regenerative capacity of skin cells in vitro. Int J Cosmet Sci 2021; 43:518-529. [PMID: 34272744 PMCID: PMC9291327 DOI: 10.1111/ics.12725] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/16/2021] [Revised: 07/02/2021] [Accepted: 07/15/2021] [Indexed: 11/28/2022]
Abstract
Objective To explore synergistic effects related to skin regeneration, peptides with distinct biological mechanisms of action were evaluated in combination with different skin cell lines in the presence or absence of niacinamide (Nam). Furthermore, the synergistic responses of peptide combinations on global gene expression were compared with the changes that occur with fractional laser resurfacing treatment, a gold standard approach for skin rejuvenation, to further define optimal peptide combinations. Methods Microarray profiling was used to characterize the biological responses of peptide combinations (+/− Nam) relative to the individual components in epidermal keratinocyte and dermal fibroblast cell lines. Cellular functional assays were utilized to confirm the synergistic effects of peptide combinations. Bioinformatics approaches were used to link the synergistic effects of peptide combinations on gene expression to the transcriptomics of the skin rejuvenation response from fractional laser treatment. Results Microarray analysis of skin cells treated with peptide combinations revealed synergistic changes in gene expression compared with individual peptide controls. Bioinformatic analysis of synergy genes in keratinocytes revealed the activation of NRF2‐mediated oxidative stress responses by a combination of Ac‐PPYL, Pal‐KTTKS and Nam. Additional analysis revealed direct downstream transcriptional targets of NRF2/ARE exhibiting synergistic regulation by this combination of materials, which was corroborated by a cellular reporter assay. NRF2‐mediated oxidative stress response pathways were also found to be activated in the transcriptomics of the early skin rejuvenation response to fractional laser treatment, suggesting the importance of this biology in the early stages of tissue repair. Additionally, the second combination of peptides (pal‐KT and Ac‐PPYL) was found to synergistically restore cellular ATP levels that had been depleted due to the presence of ROS, indicating an additional mechanism, whereby peptide synergies may accelerate skin repair. Conclusion Through combinatorial synergy studies, we have identified additional in vitro skin repair mechanisms beyond the previously described functions of individual peptides and correlated these to the transcriptomics of the skin rejuvenation response of fractional laser treatment. These findings suggest that specific peptides can act together, via complementary and synergistic mechanisms, to holistically enhance the regenerative capacity of in vitro skin cells.

[PMID: 34106933 PMCID: PMC8216527 DOI: 10.1371/journal.pntd.0009488] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/10/2020] [Revised: 06/21/2021] [Accepted: 05/20/2021] [Indexed: 12/01/2022] Open
Abstract
Mycetoma is a devastating neglected tropical infection of the subcutaneous tissue and most commonly caused by the fungus Madurella mycetomatis. Treatment of mycetoma consists of a combination of a long term antifungal treatment with itraconazole and surgery. However, treatment is associated with low success rates. Therefore, there is a need to identify novel treatments for mycetoma. CIN-102 is a synthetic partial copy of cinnamon oils with activity against many pathogenic bacteria and fungi. In this study we determined the in vitro activity of CIN-102 against 21 M. mycetomatis isolates and its in vivo efficacy in a M. mycetomatis infected Galleria mellonella larval model. In vitro, CIN-102 was active against M. mycetomatis with MICs ranging from 32 μg/mL to 512 μg/mL. 128 μg/mL was needed to inhibit the growth in 50% of tested isolates. In vivo, concentrations below the MIC of 40 mg/kg and 80 mg/kg CIN-102 prolonged larval survival, but higher concentrations of CIN-102 did not. Mycetoma is a tropical infection causing large tumorous lesions on mainly the foot. This infection is most commonly caused by the fungus Madurella mycetomatis. Mycetoma is treated with antifungal agents and surgery but with low success rates. In our search for novel treatments for mycetoma we determined if CIN-102, a synthetic oil that resembles cinnamon oil, would be therapeutic in mycetoma. We therefore determined the activity of this oil against the fungus in vitro. We found that CIN-102 could inhibit M. mycetomatis growth in vitro. To determine if CIN-102 was also active against the mycetoma grain in vivo, we determined the efficacy in our Galleria mellonella grain model. Interestingly, CIN-102 was found to be effective in the larvae at a low concentrations.

Noninvasive Analysis Using Data-Independent Acquisition Mass Spectrometry: New Epidermal Proteins That Reveal Sex Differences in the Aging Process. OXIDATIVE MEDICINE AND CELLULAR LONGEVITY 2021.

Abstract
The development of mass spectrometry has provided a method with extremely high sensitivity and selectivity that can be used to identify protein biomarkers. Epidermal proteins, lipids, and cornified envelopes are involved in the formation of the skin epidermal barrier. The epidermal protein composition changes with age. Therefore, quantitative proteomic changes may be indicative of skin aging. We sought to utilize data-independent acquisition mass spectrometry for noninvasive analysis of epidermal proteins in healthy Chinese individuals of different age groups and sexes. In our study, we completed high-throughput protein detection, analyzed protein differences with MaxQuant software, and performed statistical analyses of the proteome. We obtained interesting findings regarding ceruloplasmin (CP), which exhibited significant differences and is involved in ferroptosis, a signaling pathway significantly associated with aging. There were also several proteins that differed between sexes in the younger group, but the sex differences disappeared with aging. These proteins, which were associated with both aging processes and sex differences, are involved in signaling pathways such as apoptosis, oxidative stress, and genomic stability and can serve as candidate biomarkers for sex differences during aging. Our approach for noninvasive detection of epidermal proteins and its application to accurately quantify protein expression can provide ideas for future epidermal proteomics studies.

Abstract
INTRODUCTION Systemic cryotherapy is a popular treatment involving a short stay in a cryogenic chamber at a temperature below -100 °C. This leads to a number of physiological reactions, some of them also observed in the skin. The aim of the study was to analyze the effect of a single cryogenic treatment on selected skin characteristics (skin pH, level of hydration and TEWL - Transepidermal Water Loss) in young, healthy people. MATERIALS AND METHODS Skin characteristics in 77 young people (23.63 ± 1.36 years) were assessed. In the study, 43 women and 33 men who took part in a one-time treatment (-120 °C) lasting 3 min. Measurements were made on the forearm skin and (in men) on the face twice: before and immediately after the procedure. RESULTS Initial differences in hydration of the stratum corneum and TEWL were observed between the group of women and men. After one treatment, the examined characteristics of the forearm skin did not change, and an unfavorable increase in TEWL in men was indicated in the facial area. CONCLUSIONS A single stay in the cryogenic chamber, while maintaining the correct methodology of the treatment, is safe for the skin. The changes taking place depend on the body surface area tested, which indicates that the skin on the limbs and on the face reacts differently to the cryogenic stimulus.

Abstract
Several recent studies have reported a considerably higher overall survival (OS) rate in females in various geographic regions This study further investigates the characteristics of melanoma that contribute to OS of women residing in the United States. Chi-square, Kaplan-Meier, and Cox regression models were used to analyze differences in demographics, treatment, and survival of invasive cutaneous melanoma in men and women diagnosed from 2004 to 2016 in the National cancer database. In 316 966 patients met inclusion criteria. Men had a significantly higher median age of diagnosis at 61 years (interquartile range or IQR: 51-72) in comparison to women where the median age of diagnosis was 55 years (IQR: 43-68) (P < .0001). The most common primary site for men was the trunk (35.5%), whereas the lower extremities were the most common primary site for women (30.3%). Women had a higher 5 year (82.6%) and 10 year (73.1%) OS compared to 5 year and 10 year OS of 72.2% and 58.7%, respectively, in men (P < .0001). When adjusting for confounders, female gender was independently associated with improved OS (ref: male HR = 0.791; 95% confidence interval 0.773-0.809; P < .0001). Overall, we conclude that female gender is an independent favorable prognostic factor for melanoma survival.

Abstract
Introduction Genistein and daidzein are typical soy isoflavones with known estrogenic properties to provide protection against skin ageing in postmenopausal women and female rats. However their effect on male skin was very rarely studied. Aim This study was designed to evaluate the effect of a mixture of genistein and daidzein on male rats’ skin. Material and methods Male rats were administered this mixture in a dose of 2 or 20 mg/kg body weight (bw) per day for 5 days weekly mixed with regular rat chow, from prenatal life until sexual maturity. The female and male rats of the control group received regular rat chow. The skin epidermis thickness, number of fibroblasts in the dermis and diameter of collagen fibers in the dermis were measured using morphometric assay. The isoflavone effects on activities of antioxidant enzymes, lipid peroxides, and glutathione concentration in the skin were measured with commercially available kits. Results The thickness of the skin epidermis and collagen fibers in the dermis and amount of elastic fibers were significantly greater in the isoflavone-treated groups. Isoflavones significantly decreased catalase activity in the skin homogenates and at a higher dose inhibited lipid peroxides formation. Conclusions Our results provide further support for the contribution of isoflavones to defence mechanisms against oxidative stress in the skin and suggest that genistein and daidzein supplementation may provide protection against skin ageing in males.

Abstract
Background: Looking younger than actual age has been related to a variety of health outcomes. Optimism, self-esteem, and relationship satisfaction are important psychosocial resources for mental health. Little is known about their relation with a younger facial appearance. Objective: This study analyzed whether these psychosocial resources are associated with a younger facial appearance and if their effects were mediated through mental health. Method: A sample of N = 223 self-reporting healthy men aged 40 to 75 years filled in questionnaires to assess optimism (Life Orientation Test–Revised), self-esteem (Multidimensional Self-Esteem Scale), relationship satisfaction (Relationship Assessment Scale), and mental health (Short-Form Health Survey). Five female raters estimated the visual age of each participant from a frontal face photograph. Results: Looking younger (compared with chronological age) was correlated with optimism, relationship satisfaction, and mental health. Mediation analyses and structural equation modeling indicated that mental health mediated the association between each psychosocial resource and a younger appearance. Discussion: The results emphasize the importance of promoting psychosocial resources and mental health in men 40+ for the maintenance of good health and the deceleration of facial aging.

Abstract
The challenge of shaving is to cut the beard hair as closely as possible to the skin without unwanted effects on the skin. To achieve this requires the understanding of beard hair and male facial skin biology as both, the beard hair and the male facial skin, contribute to the difficulties in obtaining an effective shave without shaving-induced skin irritation. Little information is available on the biology of beard hairs and beard hair follicles. We know that, in beard hairs, the density, thickness, stiffness, as well as the rates of elliptical shape and low emerging angle, are high and highly heterogeneous. All of this makes it challenging to cut it, and shaving techniques commonly employed to overcome these challenges include shaving with increased pressure and multiple stroke shaving, which increase the probability and extent of shaving-induced skin irritation. Several features of male facial skin pose problems to a perfect shave. The male facial skin is heterogeneous in morphology and roughness, and male skin has a tendency to heal slower and to develop hyperinflammatory pigmentation. In addition, many males exhibit sensitive skin, with the face most often affected. Finally, the hair follicle is a sensory organ, and the perifollicular skin is highly responsive to external signals including mechanical and thermal stimulation. Perifollicular skin is rich in vasculature, innervation and cells of the innate and adaptive immune system. This makes perifollicular skin a highly responsive and inflammatory system, especially in individuals with sensitive skin. Activation of this system, by shaving, can result in shaving-induced skin irritation. Techniques commonly employed to avoid shaving-induced skin irritation include shaving with less pressure, pre- and post-shave skin treatment and to stop shaving altogether. Recent advances in shaving technology have addressed some but not all of these issues. A better understanding of beard hairs, beard hair follicles and male facial skin is needed to develop novel and better approaches to overcome the challenge of shaving. This article covers what is known about the physical properties of beard hairs and skin and why those present a challenge for blade and electric shaving, respectively.

Sex differences in the association of cutaneous melanoma incidence rates and geographic ultraviolet light exposure. J Am Acad Dermatol 2017; 76:499-505.e3. [PMID: 28413057 PMCID: PMC5407289 DOI: 10.1016/j.jaad.2016.08.027] [Citation(s) in RCA: 53] [Impact Index Per Article: 7.6] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/08/2016] [Revised: 08/10/2016] [Accepted: 08/12/2016] [Indexed: 11/30/2022]
Abstract
BACKGROUND Cutaneous melanoma (CM) incidence rates continue to increase, and the reasons are unknown. Previously, we reported a unique age-specific sex difference in melanoma that suggested additional causes other than solar ultraviolet (UV) radiation. OBJECTIVE This study attempted to understand whether and how UV radiation differentially impacts the CM incidence in men and women. METHODS CM data and daily UV index (UVI) from 31 cancer registries were collected for association analysis. A second dataset from 42 US states was used for validation. RESULTS There was no association between log-transformed female CM rates and levels of UVI, but there was a significant association between male rates and UVI and a significant association between overall rates and UVI. The 5-year age-specific rate-UVI association levels (represented by Pearson's coefficient ρ) increased with age in men, but age-specific ρ levels remained low and unchanged in women. The significant rate-UVI association in men and nonassociation in women was validated in a population of white residents of the United States. LIMITATIONS Confounders, including temperature and latitude, are difficult to separate from UVI. CONCLUSIONS Ambient UVI appears to be associated with melanoma incidence in males but not in females.

[PMID: 26763856 DOI: 10.1016/j.jse.2015.10.018] [Citation(s) in RCA: 20] [Impact Index Per Article: 2.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/28/2015] [Revised: 10/13/2015] [Accepted: 10/18/2015] [Indexed: 02/01/2023]
Abstract
BACKGROUND Propionibacterium acnes (P acnes) has been linked to chronic infections in shoulder surgery. It was recently observed during first-time shoulder surgery in healthy patients at a rate between 36% and 56%. Male gender and the anterolateral approach were reported risk factors. Because the skin biology greatly differs, we aimed to correlate skin complaints with P acnes-positive intraoperative cultures from different tissue layer samples in patients undergoing shoulder surgery for the first time. METHODS Intraoperative samples (1 skin, 1 superficial, 1 deep tissue, and 1 control sample) from 112 patients (70 men, 42 women; aged 59.2 years) were cultured. The association between the presence of P acnes in the deep or superficial tissue, or both, and 10 items of a validated preoperative questionnaire for skin pathology was explored. RESULTS The cultures were positive for P acnes in 38.4% (n = 43) of the cases. Skin samples were positive for P acnes in 8% (n = 9), superficial samples were positive in 23% (n = 26), and deep samples were positive in 30% (n = 34). Self-reported "loss of hair" was significantly negatively associated with the presence of P acnes in the superficial or deep tissue sample (P = .00028). DISCUSSION Patients who report having "loss of hair" show fewer P acnes-positive cultures in intraoperative tissue samples taken during open shoulder surgery. Whether this subgroup is at a lesser risk for P acnes infections remains to be substantiated. LEVEL OF EVIDENCE Basic Science Study; Microbiology.

Abstract
Gonadal hormones influence physiological responses to stress and cutaneous wound healing. The aim of this study was to investigate the role of gonadal hormones on cutaneous wound healing in chronically stressed mice. Male and female mice were gonadectomized, and after 25 days, they were spun daily at 115 rpm for 15 min every hour until euthanasia. Twenty-eight days after the gonadectomy, an excisional lesion was created. The animals were killed 7 or 14 days after wounding, and the lesions were collected. Myofibroblast density, macrophage number, catecholamine level, collagen deposition, and blood vessel number were evaluated. In the intact and gonadectomized groups, stress increased the plasma catecholamine levels in both genders. In intact groups, stress impaired wound contraction and re-epithelialization and increased the macrophage number in males but not in females. In addition, stress compromised myofibroblastic differentiation and blood vessel formation and decreased collagen deposition in males but not in females. In contrast to intact mice, wound healing in ovariectomized female mice was affected by stress, while wound healing in castrated male mice was not. In conclusion, gender differences contribute to the cutaneous wound healing of chronically stressed mice. In addition, androgens contribute to the stress-induced impairment of the healing of cutaneous wounds but estrogens inhibit it.
