Evaluation of psychological well-being and social impact of atrophic acne scarring: A multinational, mixed-methods study

Insights into the role of mesenchymal stem cells in cutaneous medical aesthetics: from basics to clinics

With the development of the economy and the increasing prevalence of skin problems, cutaneous medical aesthetics are gaining more and more attention. Skin disorders like poor wound healing, aging, and pigmentation have an impact not only on appearance but also on patients with physical and psychological issues, and even impose a significant financial burden on families and society. However, due to the complexities of its occurrence, present treatment options cannot produce optimal outcomes, indicating a dire need for new and effective treatments. Mesenchymal stem cells (MSCs) and their secretomics treatment is a new regenerative medicine therapy that promotes and regulates endogenous stem cell populations and/or replenishes cell pools to achieve tissue homeostasis and regeneration. It has demonstrated remarkable advantages in several skin-related in vivo and in vitro investigations, aiding in the improvement of skin conditions and the promotion of skin aesthetics. As a result, this review gives a complete description of recent scientific breakthroughs in MSCs for skin aesthetics and the limitations of their clinical applications, aiming to provide new ideas for future research and clinical transformation.

Development of solid lipid microparticles (SLMs) containing asiatic acid for topical treatment of acne: Characterization, stability, in vitro and in vivo anti-acne assessment

Solid lipid microparticles (SLMs) represent a promising approach for drug delivery in anti-acne applications. In this study, asiatic acid-loaded SLMs (AASLMs) were prepared by melt emulsification method in conjunction with freeze-drying. Comprehensive evaluations comprised particle size, %entrapment efficiency (%EE), %labeled amount (%LA), surface morphology, stability, %release, %skin permeation, and anti-acne activity. The AASLMs exhibited an average particle size ranging from 7.46 to 38.86 µm, with %EE and %LA falling within the range of 31.56 to 100.00 and 90.43 to 95.38, respectively. The AASLMs demonstrated a spherical shape under scanning electron microscopy, and maintained stability over a 3-month period. Notably, formulations with 10 % and 15 % cetyl alcohol stabilized with poloxamer-188 (specifically F6 and F12) displayed a minimum inhibitory concentration (MIC) value of 75 mg/ml against Cutibacterium acnes. Furthermore, F12 exhibited a higher %release and %skin permeation compared to F6 over 24 h. In a single-blind clinical trial involving fifteen participants with mild-to-moderate acne, F12 showcased its potential not only in reducing porphyrin intensity and enhancing skin barriers but also in significantly improving skin hydration and brightness. However, further investigations with larger subject cohorts encompassing diverse age groups and genders are necessary to thoroughly establish the performance of the developed AASLMs.

Sleep quality correlates with effectiveness of ultrapulse fractional CO2 laser in the treatment of facial atrophic acne scars

Ultrapulse fractional CO2 laser is effective for acne atrophic scars. Whether this effectiveness is affected by sleep quality remains unclear. Aiming to investigate the relationship between sleep quality and postoperative effectiveness, a retrospective clinical study was conducted, enrolling 83 patients with atrophic acne scar. Sleep quality was measured by the Pittsburgh Sleep Quality Index (PSQI) questionnaire at 3 months after the end of the first treatment. The ECCA (échelle d'évaluation clinique des cicatrices d'acné) scale was used to evaluate the clinical effectiveness before and at 3 months after treatment. The patients were divided into a mild to moderate improvement group and a good to excellent improvement group, based on whether they achieved a 50% ECCA improvement rate. PSQI score was higher in the mild and moderate improvement group than in the good to excellent improvement group (7.6 ± 4.5 vs 3.8 ± 1.7, p < 0.001). Multivariate logistic regression showed that both PSQI score (odds ratio = 0.6 [95% CI = 0.5-0.8], p < 0.001) and scar type were correlated with postfractional CO2 laser effectiveness. Pearson correlation analysis suggested that PSQI score was negatively correlated with ECCA decline score (r = -0.6139, p < 0.0001). Receiver operating characteristic curve analysis showed that PSQI score (area under the curve = 0.759) and scar type (area under the curve = 0.737) were all closely correlated with postoperative effectiveness, without statistical difference between their accuracies (p = 0.647). Decision curve analysis demonstrated that both PSQI score and scar type correlated with postoperative effectiveness. Our results demonstrated that sleep quality correlates with the postoperative effectiveness of ultrapulse fractional CO2 laser in the treatment of atrophic acne scars.

The effects of scar in psychological disorder: A bibliometric analysis from 2003 to 2022

Scars are fibrous tissues that replace normal tissue during the wound healing process. Scarring can lead to low self-esteem, social impairment, depression, anxiety, and other psychiatric and psychological distress, necessitating a comprehensive understanding of the latest perspectives, topical research, and directions in scarring-mental health. This is a biblioshiny and VOSviewer based bibliometric analysis study. All data were obtained from the Web of Science, and a total of 664 articles from 2003 to 2022 met the criteria. The last 7 years have been a period of rapid growth in the field, with 2022 having the highest number of articles. The United States is the core country with the highest production and citation rate. The most cited literature was written in 2003 by Van Loey NE et al. Van Loey NE is the most prolific and influential author in this field. The top five popular keywords include "quality of life", "depression", "management", "anxiety", and "prevalence". The paper concludes that the current focus of scholars in the field is on the treatment of scars and that multidisciplinary treatment of such patients is worth exploring. These findings provide relevant researchers with the current state of research and possible future directions in this field.

The Acne Education Project: An educational initiative to improve acne health literacy and promote help-seeking behavior in young adolescents

BACKGROUND

Acne vulgaris is an inflammatory skin condition that is associated with poor acne health literacy. Diminished acne health literacy leads to delays in the access of health care, resulting in mismanagement, disfigurement, and psychosocial morbidity. This study evaluates the potential role of early acne education in young adolescent populations to improve acne health literacy and facilitate help-seeking behavior.

METHODS

The Acne Education Project is a Canadian medical student-led initiative founded to create evidence-based resources to increase acne health literacy. A 45-min interactive Zoom presentation on acne was created and delivered to 2292 students ages 9-13 in British Columbia, Canada. A quality improvement survey was administered pre-intervention, immediate post-intervention, and 1-month post-intervention to evaluate baseline acne knowledge and knowledge retention to guide presentation and resource development.

RESULTS

Responses from 676 unique individuals were collected. Analysis using linear mixed-effects models demonstrated that respondents were significantly more confident in their general knowledge of acne, strategies to prevent acne, identification of psychosocial sequelae of acne, and more willing to seek help immediately post-intervention (p < .001). Differences in scores were not fully preserved in magnitude at the 1-month post-intervention assessment. However, students still scored significantly higher in all categories compared to the pre-intervention baseline (p < .001).

CONCLUSION

Our findings suggest that early acne education can improve acne health literacy and promote help-seeking behavior. Given the potential long-term implications, further research is needed to explore the long-term impact of early acne education and the benefit of integrating acne education into the public education curriculum in Canada.

The impact of visible scars on well-being and quality of life: An international epidemiological survey in adults

INTRODUCTION

Scars are visible marks from various causes, including surgery, skin injury, burning or dermatological disease, and may impact the quality of life.

OBJECTIVE

To assess the impact of scars on quality of life (QoL).

MATERIAL AND METHODS

Data about sociodemography, presence, origin, and symptoms of scars were collected using an Internet survey between April and May 2020. Overall, 11,100 individuals answered the survey. In total, 48.5% of the responders had at least one scar of less than 1 year of age. Scars were mainly reported on the abdomen and face. Globally, 28.9% of subjects with recent scars reported pain, 23.7% reported burning, 35.0% reported itching, and 44.1% reported redness. Subjects were most frequently bothered by the visibility of their scars and the presence of marks. Incidences were significantly higher than for those with older scars. The average DLQI score was 7.44; it decreased to 2.90 after 1 year. Subjects with scars aged less than 3 months had their QoL more frequently impacted (33.9%) than those with scars aged 12 months or more (10.2%). In subjects reporting skin discomfort, clinical symptoms significantly impacted body movement, choice of clothes, leisure activities, and sexual life more than in those reporting no skin discomfort. Moreover, subjects felt significantly more impacted in their daily lives due to their skin discomfort. When feeling bothered by the visibility of their scars, significantly more subjects were also impacted in their body movement, choice of clothes, leisure activities, and sexual life than those subjects who did not feel bothered. Moreover, significantly more subjects felt embarrassed.

CONCLUSION

Scars significantly impact the subjects' quality of life. This impact is even more important when caused by recent and visible scars, with a lower DLQI score in subjects with more aged than in those with recent scars.

Subcision for Atrophic Acne Scarring: A Comprehensive Review of Surgical Instruments and Combinatorial Treatments

Subcutaneous incisionless surgery, also known as subcision, is a minimally invasive procedure that is commonly indicated for the treatment of atrophic acne scars. In recent years, many new techniques have been developed to maximize results from this procedure. This review article aims to identify an updated list of instruments and combinatorial treatments available for atrophic acne scar patients undergoing subcision. We constructed a comprehensive PubMed search term and performed triple-blinded screening on all resulting studies for mentions of subcision as indicated by acne scarring. Our results show that there are four main categories of subcision tools that are commonly employed to treat atrophic acne scars: needles, cannulas, wires, and blunt-blade instruments. Usage of these devices varies by scar depth, personal preference, and combinatorial treatment options. Overall, subcision is a particularly effective treatment for atrophic acne scars, and there is vast potential for further innovation with this technique.

Beyond the Surface: A Deeper Look at the Psychosocial Impacts of Acne Scarring

Post-acne scarring is a common consequence of acne vulgaris with no universal cure. Although there have been many recent advances to address acne scars physically, there is still a lack of research that investigates their psychosocial impacts. Our comprehensive PubMed search presents an overview of existing information to highlight known sources of mental distress caused by post-acne scarring, both related to and independent of the psychosocial detriments caused early on by active acne. The literature indicates that acne scarring is a distinct condition from acne vulgaris and therefore requires a comprehensive clinical approach unique from those available for active acne.

Projective Personification Approach to the Experience of People With Acne and Acne Scarring-Expressing the Unspoken

Importance

The association of acne with emotional and social well-being is not limited to active acne because acne scarring can extend long after cessation of active lesions.

Objective

To explore the psychosocial burden of facial and truncal acne (FTA) and acne scars (AS) in a spontaneous manner using qualitative research.

Design, Setting, and Participants

This qualitative study recruited participants via local panels. A personification exercise, "Letter to my Disease," was developed for participants of 2 independent arms, FTA and AS, of an international qualitative study in the form of letter completion.

Main Outcomes and Measures

Study outcomes comprised perceptions, psychosocial effects of FTA and AS, and coping behaviors.

Results

A total of 60 participants were recruited for the FTA and AS study. Among participants with FTA, 17 were women (57%), 21 (70%) were aged 13 to 25 years, and 9 (30%) were aged 26 to 40 years. Twenty-six (87%) participants had severe active acne and 4 (13%) had moderate active acne. Among participants with AS, 18 were women (60%), 9 (30%) were aged 18 to 24 years, and 21 (70%) were aged between 25 and 45 years. Of these 60 participants, 56 (FTA, 28 and AS, 28) completed the projective exercise, "Letter to my Disease," the analysis of which is presented in the current study. During completion of the letter exercise, participants spontaneously expressed emotional and physical burden as well as the social stigma associated with their skin condition. Three major themes emerged, namely, (1) burden of the condition, (2) attitudes and beliefs, and (3) relationship to the personified condition.

Conclusions and Relevance

Consistent with their skin condition, participants associated acne, through personification, with the character of an intruder and unwanted companion responsible for their poor self-esteem and emotional impairment. The findings of the joint analyses of letters (FTA and AS), as a catalytic process and free-expression space, outline the continuous burden of active acne starting from adolescence and then continuing into adulthood and beyond active lesions with AS, and highlight the struggle for self-acceptance.

Platelet-rich plasma in the treatment of scars, to suggest or not to suggest? A systematic review and meta-analysis

Despite the rising trend for applying platelet-rich plasma (PRP) in the management of various types of scars, there is no convincing evidence supporting its use. This motivated us to review the randomized clinical trials that examine the effectiveness and safety of PRP, alone or in combination with other methods, for the management of atrophic or hypertrophic/keloidal scars. The Web of Science, Scopus, Google Scholar, and Cochrane Library databases were systematically searched until September 1^st , 2020. Thirteen clinical trials were enrolled in the meta-analysis, and 10 more were reviewed for their results. The random effect meta-analysis method was used to assess the effect size of each outcome for each treatment type, and I² was used to calculate the statistical heterogeneity between the studies. Patients treated with PRP experienced an overall response rate of 23%, comparable to the results seen with laser or micro-needling (22% and 23%, respectively) When used alone, moderate improvement was the most frequently observed degree of response with PRP (36%) whereas, when added to laser or micro-needling, most patients experienced marked (33%, 43%, respectively) or excellent (32% and 23%, respectively) results. Concerning the hypertrophic/keloid scars, the only study meeting the required criteria reported a better improvement and fewer adverse effects when PRP was added to the intralesional corticosteroids. Platelet-rich plasma appears to be a safe and effective treatment for various types of atrophic scars. In addition, when added to ablative lasers or micro-needling, it seems to considerably add to the efficacy of treatment and reduce the side effects.
