Vitamin D and wound healing: Assessing skin barrier function and implications for chloasma treatment

Abstract

Chloasma, which is distinguished by irregularities in the pigmentation of skin, poses substantial challenge in the field of dermatology. The regulatory influence of vitamin D on the functions of skin cells implies that it may have the capacity to effectively treat chloasma and promote wound healing. To assess the efficacy of vitamin D in chloasma treatment and its impact on the function of skin barrier during the process of wound healing. The research spanned from April 2022 to September 2023, in Shanghai, China, examined 480 individuals who had been diagnosed with chloasma. A double-blind, placebo-controlled clinical trial was utilized to evaluate effectiveness of topical vitamin D3 in treatment of chloasma. Concurrently, randomized control trial investigated the effects of ingested vitamin D3 supplements on the process of wound healing. Transepidermal water loss (TEWL), chloasma severity score changes, wound size reduction and skin hydration levels were critical performance indicators. Statistically, the severity scores of chloasma decreased significantly in the vitamin D treatment group at 3 and 6 months compared with the placebo (p < 0.05). The Vitamin D group exhibited superior wound healing outcomes, including more substantial reduction in lesion size and enhanced skin barrier function, as evidenced by increased skin hydration and decreased TEWL (p < 0.05). Vitamin D substantially mitigated the severity of chloasma and has beneficial effect on wound healing and integrity of the skin barrier. Based on the results obtained, vitamin D exhibited promise as a therapeutic intervention in the field of dermatology, specifically in treatment of chloasma and promotion of wound recovery.

Sternal wound infections following internal mammary artery grafts for a coronary bypass: A meta‐analysis

Abstract

The meta-analysis aims to evaluate and compare the sternal wound infections following internal mammary artery grafts for a coronary bypass. Examinations comparing bilateral internal mammary artery to single internal mammary artery for coronary artery bypass grafting were among the meta-analyses from various languages that met the inclusion criteria. Using dichotomous random- or fixed-effect models, the results of these investigations were examined, and the Odd Ratio (OR) with 95% confidence intervals (CIs) was computed. A total of 31 examinations from 2001 to 2023 were recruited for the current analysis including 181 503 personals with coronary artery bypass grafting. Bilateral internal mammary artery had significantly higher sternal wound infection (OR, 1.51; 95% CI, 1.37–1.68, p < 0.001), superficial sternal wound infection (OR, 1.72; 95% CI, 1.16–2.56, p = 0.007), deep sternal wound infection (OR, 1.62; 95% CI, 1.41–1.86, p < 0.001), sternal wound infection in diabetics (OR, 1.48; 95% CI, 1.16–1.90, p = 0.002), sternal wound infection in elderly (OR, 1.38; 95% CI, 1.22–1.57, p < 0.001), sternal wound infection in pedicled preparation (OR, 1.70; 95% CI, 1.30–2.23, p < 0.001) and sternal wound infection in skeletonized preparation (OR, 1.40; 95% CI, 1.09–1.81, p = 0.009) compared to single internal mammary artery in personals with coronary artery bypass grafting. Bilateral internal mammary artery grafting is linked to a higher risk of impaired wound healing, particularly in diabetic individuals, elderly, pedicled preparation, and skeletonized preparation. Nevertheless, caution should be exercised while interacting with its values since examinations were performed by different surgeons with different skills on different types of personals.

Assessing the role of combination of stem cell and light‐based treatments on skin wound repair: A meta‐analysis

Abstract

The meta-analysis aims to evaluate and compare the impact of the combination of stem cells (SCs) and light-based treatments (LBTs) on skin wound (SW) repair. Examinations comparing SCs to LBT with SCs for SW repair was among the meta-analysis from various languages that met the inclusion criteria. Using continuous random-effect models, the results of these investigations were examined, and the mean difference (MD) with 95% confidence intervals was computed (CIs). Seven examinations from 2012 to 2022 were recruited for the current analysis including 106 animals with SWs. Photobiomodulation therapy (PBT) plus SCs had a significantly higher wound closure rate (WCR) (MD, 9.08; 95% CI, 5.55–12.61, p < 0.001) compared to SCs in animals with SWs. However, no significant difference was found between PBT plus SCs and SCs on wound tensile strength (WTS) (MD, 2.01; 95% CI, −0.42 to 4.44, p = 0.10) in animals with SWs. The examined data revealed that PBT plus SCs had a significantly higher WCR, however, no significant difference was found in WTS compared to SCs in animals with SWs. Nevertheless, caution should be exercised while interacting with its values since all the chosen examinations were found with a low sample size and a low number of examinations were found for the comparisons studied for the meta-analysis.
