Prospective Randomized Double-Blind Vehicle-Controlled Study of Topical Coconut and Sunflower Seed Oil-Derived Isosorbide Diesters on Atopic Dermatitis.

Background: Preliminary studies support the use of topical coconut and sunflower seed oil for atopic dermatitis (AD). However, standardized topical formulations of fatty acids from these sources have not been studied. Objective: This study investigates whether coconut oil- and sunflower seed oil-derived isosorbide diesters can be used in conjunction with colloidal oatmeal to improve itch, AD severity, and the need for topical steroids in adults. Methods: This was a single-center, 4-week, randomized, double-blind, and vehicle-controlled study conducted between 2021 and 2022. Thirty-two male and female adults with mild-to-moderate AD were enrolled and completed the study. Participants were randomized to receive either 0.1% colloidal oatmeal (vehicle) or isosorbide diesters (IDEAS, 4% isosorbide dicaprylate and 4% isosorbide disunflowerseedate) along with 0.1% colloidal oatmeal. The main outcomes of the study were changes in the visual analogue rating of itch and 75% improvement in the Eczema Area and Severity Index score (EASI 75) at 4 weeks. Other measures included the use of topical steroids and the relative abundance of skin Staphylococcus aureus. Results: Participants in the IDEAS group had a 65.6% improvement in itch compared with 43.8% in the vehicle group (P = 0.013). In total, 56.5% and 25% of the those in the IDEAS and vehicle groups, respectively, achieved EASI 75 at 4 weeks (P = 0.07). There was no difference in skin hydration or transepidermal water loss. The relative abundance of S. aureus was decreased in the IDEAS group at week 4 compared with no change in the vehicle group (P = 0.044). Topical corticosteroid use increased in the vehicle group compared with a decrease in the IDEAS group at week 1 (292.5% vs 24.8%; P value = 0.039) and week 2 (220% vs 46%; P value = 0.08). Conclusions: Topical application of emollients containing coconut oil- and sunflower seed oil-derived fatty esters may improve itch, reduce topical steroid use, and reduce the relative abundance of S. aureus in mild-to-moderate AD. CTR number: NCT04831892.

Effect of Pulsing Digital Heating Devices on Skin Parameters, Subjective Pain, Mood, and Anxiety.

A common pitfall of many conventional heat therapy methods is the propensity to lose heat over time and the need for reheating and reapplication. Pain-relieving digital heating devices are now available that can be held in place on the body via adhesive or magnet and provide pulsed heat. However, the safety of such devices among different ages and skin types must be established. We conducted a prospective, open-label study to assess the effect of three consecutive thirty-minute treatment cycles on skin parameters and pain. Effects on mood and anxiety were secondarily assessed. 22 adult participants (20 female, 2 male; mean 58 ± 17.63 years) were recruited. The participants attended one visit with heating device intervention and a follow-up visit after 7-10 days. A 97% significant increase in transepidermal water loss was observed immediately following intervention (p = 8.04487 × 10-7), although significance was not sustained at follow-up. There was an increase along the red/green axis at 13/14 treatment locations immediately following treatment, although only four locations remained significantly increased at follow-up. Pain non-significantly decreased immediately following treatment (p = 0.057). A 38.6% decrease in subjective anxiety was observed immediately after treatment (p = 0.0139), and scores remained non-significantly reduced at follow-up (19.3% reduction from baseline; p = 0.1397). The heating devices elicit temporary changes to the skin, although the lack of significance at follow-up suggests that the devices can be safely used without long-term changes in skin color or barrier status.

Systematic review and estimated cost-efficacy of biologics compared with narrowband ultraviolet B light for the treatment of moderate to severe psoriasis and atopic dermatitis.

Psoriasis and atopic dermatitis are chronic inflammatory skin conditions, each affecting about 2-3% of the United States adult population. Phototherapy, such as narrowband ultraviolet-B (NB-UVB) therapy have been employed for the treatment of both psoriasis and atopic dermatitis for decades. More recently, systemic biologics have been approved by the Food and Drug Administration (FDA), representing a great advancement in dermatology. No comprehensive study to date has compared the cost efficacy of phototherapy compared to FDA-approved biologics for the treatment of psoriasis and atopic dermatitis. We pursued a systematic review of the literature for studies assessing efficacy of NB-UVB or biologics with endpoints including the Psoriasis Area and Severity Index (PASI) and the Eczema Area and Severity Index (EASI). Thirty-four studies including 55 treatment regimens and 5,123 patients were included in the analysis. Phototherapy costs were estimated with Medicare fee schedules for phototherapy-related current procedural terminology code (CPT), and biologic costs were estimated with wholesale acquisition cost (WAC). Total costs to achieve PASI 75 or EASI 75 in each study were standardized to a single month, the "adjusted cost," and exploited to a year, the "effective yearly cost," allowing direct cost-efficacy comparison despite different durations of treatment described in studies. The psoriasis analysis found NB-UVB to be the most cost-effective therapy, with an adjusted monthly cost of $1714.00 per PASI 75. Infliximab was the least expensive biologic, with an adjusted monthly cost of $2076.00 to $2502.00 per PASI 75. For atopic dermatitis, no NB-UVB studies utilized EASI 75 as their outcome measure, hindering the ability to directly compare cost effectiveness for the treatment of atopic dermatitis. However, all NB-UVB studies depicted a reduced treatment cost per treatment period compared to studies assessing biologics, although this comparison does not account for efficacy. The results depict NB-UVB to be the most cost effective for the treatment of psoriasis and the least expensive per treatment period for the treatment of atopic dermatitis. However, certain factors need to be taken into account. Biologics may be more effective for more severe disease, do not require multiple weekly clinic visits, and the ease for patient compliance may lead some to favor biologic therapy. This study is necessary to allow physicians, patients, and health systems to make informed decisions regarding cost-efficacy for a variety of treatment options.

Randomized Double-Blind Placebo-Controlled Supplementation with Standardized Terminalia chebula Fruit Extracts Reduces Facial Sebum Excretion, Erythema, and Wrinkle Severity.

Terminalia chebula (TC) is a medicinal plant that exhibits antioxidant, anti-inflammatory, and antibacterial properties and that is widely used in Ayurveda and herbal formulations. However, the skin effects of TC as an oral supplement have not been studied. The objective of this study is to determine if oral TC fruit extract supplementation can modulate the skin's sebum production and reduce the appearance of wrinkles. A prospective double-blind placebo-controlled study was conducted on healthy females aged 25-65. Subjects were supplemented with an oral placebo or Terminalia chebula (250 mg capsule, Synastol TC) capsules twice daily for eight weeks. A facial image collection and analysis system was used to assess the facial appearance of wrinkle severity. Standardized, non-invasive tools were used to measure facial moisture, sebum production, transepidermal water loss, melanin index and erythema index. For those who had a baseline sebum excretion rate >80 ug/cm2, TC supplementation produced a significant decrease in forehead sebum excretion rate compared to the placebo at four weeks (-17 decrease vs. 20% increase, p = 0.07) and at eight weeks (-33% decrease vs. 29% increase, p < 0.01). Cheek erythema decreased by 2.2% at eight weeks, while the placebo treatment increased cheek erythema by 1.5% (p < 0.05). Facial wrinkles decreased by 4.3% in the TC group and increased by 3.9% in the placebo group after eight weeks of supplementation (p < 0.05). TC supplementation reduces facial sebum and improves the appearance of wrinkles. Future studies should consider evaluating oral TC as adjuvant therapy for acne vulgaris.

Prospective Randomized, Double-Blind, Placebo-Controlled Study of a Standardized Oral Pomegranate Extract on the Gut Microbiome and Short-Chain Fatty Acids.

Punica granatum L., commonly known as the pomegranate, is an abundant source of polyphenols, including hydrolyzable ellagitannins, ellagic acid, anthocyanins, and other bioactive phytochemicals shown to be effective in defending against oxidative stress, and has immunomodulatory activities. Ellagitannins, and their hydrolyzed product ellagic acid, interact with the gut microbiota to yield secondary metabolites known as urolithins that may have health benefits. The objective of this study was to determine the effects of supplementation with a standardized punicalagin-enriched pomegranate extract, Pomella® (250 mg), on the gut microbiome, circulating short-chain fatty acids, and gut microbial-derived ellagitannin metabolite urolithins. A randomized, double-blind, placebo-controlled study was conducted over 4 weeks on healthy volunteers aged 25-55 years. Subjects were randomly assigned to receive either an oral supplement containing 75 mg of punicalagin or an oral placebo. Stool sample collection and venipuncture were performed to analyze the gut microbiome, SCFAs, and urolithin. There was no significant change in the gut microbial diversity in both cohorts after 4 weeks of intervention, but there was a significantly increased relative abundance of Coprococcus eutectus, Roseburia faecis, Roseburia inullnivorans, Ruminococcus bicirculans, Ruminococcus calidus, and Faecalibacterium prausnitzii. Pomegranate extract (PE) supplementation led to the augmentation of circulating propionate levels (p = 0.02) and an increasing trend for acetate levels (p = 0.12). The pomegranate extract (PE) supplementation group had an increased level of circulating urolithins compared to the placebo group (6.6% vs. 1.1%, p = 0.13). PE supplementation correlated with shifts in the gut microbiome and with higher circulating levels of propionate and acetate. Further studies should explore the implications in larger cohorts and over a longer duration.

Prospective Randomized Double-Blind Placebo-Controlled Study of Oral Pomegranate Extract on Skin Wrinkles, Biophysical Features, and the Gut-Skin Axis.

(1) Background: The pomegranate fruit (Punica granatum L.) has been widely used in traditional medicine and has increasingly gained popularity among consumers in order to manage different facets of health. The objective of this study was to evaluate the effects of the fruit extract of P. granatum L. on different parameters of skin health. (2) Methods: A prospective, double-blind placebo-controlled study was conducted on both healthy males and females aged 25−55 years. Subjects were supplemented with a standardized punicalagin enriched oral pomegranate extract [Pomella® (Verdure Science, Noblesville, IN, USA), PE group] or a placebo (control group) daily for four weeks. Changes in wrinkle severity, facial biophysical properties, skin microbiome, and the gut microbiome were assessed. (3) Results: The PE group had significant reductions in wrinkle severity (p < 0.01) and a decreasing trend in the forehead sebum excretion rate (p = 0.14). The participants in the PE group with a higher relative abundance of Eggerthellaceae in the gut had a decrease in their facial TEWL (p < 0.05) and wrinkle severity (p = 0.058). PE supplementation led to an increase in the Staphylococcus epidermidis species and the Bacillus genus on the skin. (4) Conclusions: Overall, the study demonstrated improvements in several biophysical properties, wrinkles, and shifts in the skin microbiome with oral PE supplementation in healthy subjects.

GC-MS Analysis, Molecular Docking and Pharmacokinetic Properties of Phytocompounds from Solanum torvum Unripe Fruits and Its Effect on Breast Cancer Target Protein.

This study was designed to identify phytocompounds from the aqueous extract of Solanum torvum unripe fruits using GC-MS analysis against breast cancer. For this, the identified phytocompounds were subjected to perform molecular docking studies to find the effects on breast cancer target protein. Pharmacokinetic properties were also tested for the identified phytocompounds to evaluate the ADMET properties. Molecular docking studies were done using docking software PyRx, and pharmacokinetic properties of phytocompounds were evaluated using SwissADME. From the results, ten best compounds were identified from GC-MS analysis against breast cancer target protein. Of which, three compounds showed very good binding affinity with breast cancer target protein. They are ergost-25-ene-3,6-dione,5,12-dihydroxy-,(5.alpha.,12.beta.) (- 7.3 kcal/mol), aspidospermidin-17-ol,1-acetyl-16-methoxy (- 6.7 kcal/mol) and 2-(3,4-dichlorophenyl)-4-[[2-[1-methyl-2-pyrrolidinyl]ethyl amino]-6-[trichloromethyl]-s-triazine (- 6.7 kcal/mol). Further, docking study was performed for the synthetic drug doxorubicin to compare the efficiency of phytocompounds. The binding affinity of ergost-25-ene-3,6-dione,5,12-dihydroxy-,(5.alpha.,12.beta.) is higher than the synthetic drug doxorubicin (- 7.2 kcal/mol), and the binding affinity of other compounds is also very near to the drug. Hence, the present study concludes that the phytocompounds from the aqueous extract of Solanum torvum unripe fruits have the potential ability to treat breast cancer.

Antioxidants Supplementation in Acute Amitriptyline Abuse for Pain.

The fundamental aim of this study is to establish the role of antioxidant supplementation in alleviating acute amitriptyline induced oxidative stress. The effect of supplementation was compared on treatment of acute amitriptyline intoxication cases for pain management, with alpha lipoic acid (ALA) alone or with vitamin C, with that of healthy individuals (group I), and those receiving only routine standard treatment (RST) as control (group II). A total of 132 human subjects divided into 5 groups were supplemented with either placebo, RST, RST with vitamin C, RST with ALA, or RST with vitamin C, and ALA. Results of this study revealed that the decrease in the level of oxidative stress and enzyme activity was observed among those supplemented with either alpha lipoic acid alone or along with vitamin C, with a slightly more decrease in the latter group. P value of < 0.001 was considered statistically significant. The percentage of benefit of treatment on supplementation with vitamin C and alpha lipoic acid showed a marked increase in group V cases after supplementation with both in combination. The results provided that the oxidative stress induced by acute amitriptyline poisoning is comparatively decreased by supplementation with antioxidants like alpha lipoic acid and vitamin C, than those only on routine standard treatment.

Antitumor activity of Albizia lebbeck L. against Ehrlich ascites carcinoma in vivo and HeLa and A549 cell lines in vitro.

AIM OF THE STUDY: The aim of the present study was to explore the antitumor activity of the ethanolic extract of Albizia lebbeck L. pods against Ehrlich ascites carcinoma (EAC) in Swiss albino mice and its cytotoxic effect against HeLa and A549 cell lines in vitro. MATERIALS AND METHODS: Antitumor activity of ethanolic extract of A. lebbeck L. (ALEE) pods was evaluated in Swiss albino mice against EAC cell lines at the doses of 200 and 400 mg/kg body weight which were given by intraperitoneal route of administration and was compared with 5-fluorouracil (5-FU), the reference standard. The extract and 5-FU were administered for 14 consecutive days. After 24 h of the last dose and 18 h of fasting, the mice were sacrificed and the antitumor effect of ALEE was assessed by evaluating tumor volume, viable and nonviable tumor cell count, increase in life span, and hematological parameters of EAC-bearing hosts.In vitro cytotoxicity has been assessed using (2,3-bis[2-Methoxy-4-nitro-5sulfophenyl]-2H-tetrazolium-5-carboxyanilide inner salt assay method and was compared with cisplatin, the reference standard. RESULTS: ALEE showed direct cytotoxicity on EAC cells in a dose-dependent manner. ALEE exhibited a significant (P < 0.001) decrease in the body weight, tumor volume, viable cell count, tumor weight, and elevated the life span of EAC tumor-bearing mice. Hematological profile such as red blood cell, hemoglobin, white blood cell, and platelet count was reverted to the normal level in ALEE-treated mice. CONCLUSION: The results showed that the ethanolic extract of A. lebbeck L. has a powerful antitumor activity because it was effective in significantly inhibiting the tumor growth in both in vivo and in vitro cancer cell lines.

Prospective Randomized Controlled Trial on the Effects of Almonds on Facial Wrinkles and Pigmentation.

BACKGROUND: Almonds have long been studied as a rich source of fatty acids, phytochemical polyphenols and antioxidants such as vitamin E. A recent study compared almond supplementations to a calorie-matched intervention for 16 weeks, yielding statistically significant improvement in wrinkle severity in postmenopausal women with Fitzpatrick skin types I and II that received almonds. This study furthers that assessment with a larger population and duration of 24 weeks to assess the influence of almond consumption on wrinkle severity, skin pigmentation and other skin biophysical profiles. OBJECTIVE: To investigate the effects of almond consumption on photoaging such as wrinkles and pigment intensity as well as facial biophysical parameters such as sebum production, skin hydration and water loss. DESIGN AND INTERVENTIONS: A prospective, randomized controlled study assessed postmenopausal women with Fitzpatrick skin types I or II who consumed 20% of their daily energy consumption in either almonds or a calorie-matched snack for 24 weeks. A facial photograph and image analysis system was used to obtain standardized high-resolution photographs and information on wrinkle width and severity at 0, 8, 16 and 24 weeks. Measurements of transepidermal water loss (TEWL), skin pigmentation, skin hydration and sebum production were also completed at each visit. RESULTS: The average wrinkle severity was significantly decreased in the almond intervention group at week 16 and week 24 compared to baseline by 15% and 16%, respectively. Facial pigment intensity was decreased 20% in the almond group at week 16 and this was maintained by week 24. There were no significant differences in skin hydration or TEWL in the almond group compared to the control, although sebum excretion was increased in the control group. CONCLUSION: The daily consumption of almonds may improve several aspects of photoaging such as facial wrinkles and pigment intensity in postmenopausal women. In conclusion, the daily consumption of almonds may contribute to the improvement of facial wrinkles and reduction of skin pigmentation among postmenopausal women with Fitzpatrick skin types I and II.

Alternative Treatment Approaches to Small Intestinal Bacterial Overgrowth: A Systematic Review.

Background: Broad-spectrum antibiotics are the first-line treatment for small intestinal bacterial overgrowth (SIBO). However, many antibiotics have a considerable side-effect profile and SIBO commonly reoccurs after successful eradication with antibiotics. Alternative therapies such as probiotics, therapeutic diets, and herbal medicines have been used to individualize SIBO management, particularly in recalcitrant cases. Objectives: The objective of this review is to evaluate the role of alternative therapies in SIBO treatment. Data Sources: EMBASE, MEDLINE, and the Cochrane Central Register were systematically searched for clinical studies evaluating alternative therapies in the management of SIBO. Study Eligibility Criteria: Human studies in which an alternative intervention was used to treat SIBO were included. Alternative interventions were defined as an intervention that included a probiotic supplement, herbal preparation, or a dietary change. Randomized controlled trials (RCTs), nonrandomized clinical trials with or without a control, and crossover studies were included. Study Appraisal: The following information was extracted from the selected studies: study type, study participants, SIBO subtype, intervention, comparison, outcome measures, relevant results, relevant side effects, and Jadad score. Results: Eight studies met inclusion criteria. The studies evaluated probiotics (n = 5), therapeutic diet (n = 1), and herbal medicines (n = 2). Among these studies, there were four RCTs, two open-label single-arm studies, one randomized, double-blind crossover study, and one two-arm open-label study with crossover. Main results are summarized. Limitations: There may be studies not captured by the defined search criteria. Additionally, studies used different methodologies in both breath testing and measurement of clinical symptoms, making it difficult to draw conclusions on SIBO eradication and symptom improvement across studies. Conclusions and Implications: Our findings suggest preliminary evidence for a role of alternative therapies in the treatment of SIBO. However, robust clinical trials are generally lacking. Existing studies tend to be small and lack standardized formulations of treatment. Breath testing protocols and clinical symptom measurement greatly varied between studies. Large-scale, randomized, placebo-controlled trials are needed to further evaluate the best way to utilize alternative therapies in the treatment of SIBO.

A Systematic Review of Nutrition, Supplement, and Herbal-Based Adjunctive Therapies for Vitiligo.

Background: Vitiligo is an autoimmune skin condition that affects people globally anywhere, from <0.1% to more than 8% of individuals. The disease destroys skin melanocytes, resulting in a patchy depigmentation of the skin. About 50% of all patients develop the disease before their 20s. Methods: We systematically searched the literature and reviewed the evidence for the use of nutritional supplements and diet in the management of vitiligo. Embase and Medline were searched for diet, herbal, and nutrition-based clinical studies. Additional filters were applied that looked for controlled trial or randomized controlled trial and article or article in press or letter and English and clinical study. We selected clinical studies in humans that showed how diet or natural supplements can improve the symptoms of vitiligo in all of our searches. Results: There were 62 manuscripts that resulted from the PubMed search and 259 from the Embase search. A final of 26 studies were reviewed, and other supplemental case and case-control studies were used to introduce diet components that may influence either exacerbation or amelioration of vitiligo. Possible mechanisms of action are introduced for natural and supplemental interventions. Conclusion: Some of the supplements reviewed include Gingko biloba, oral Polypodium leucotomos, alpha lipoic acid, vitamins B12, D, and E, folic acid, phenylalanine, canthaxanthin, Nigella sativa oil, and other combined herbal bio-actives. Overall, the growing evidence is promising, but more studies are needed in this area to further explore the impact that supplements and diet can have on vitiligo management. The most promising therapies included oral phenylalanine as adjuvant therapy with UVA therapy, oral G. biloba as monotherapy, both of which can be used with other traditional therapies, and oral P. leucotomos with phototherapy or photochemotherapy.

Modulatory Effects of Triphala and Manjistha Dietary Supplementation on Human Gut Microbiota: A Double-Blind, Randomized, Placebo-Controlled Pilot Study.

Objectives: Triphala (which contains Emblica officinalis, Terminalia bellerica, and Terminalia chebula) and manjistha (Rubia cordifolia), have received increased clinical attention. The aim of the study was to evaluate the effects of triphala, manjistha, or placebo dietary supplementation on gut microbiota as such studies in humans are lacking. Design: This was a 4-week randomized, double-blind, placebo-controlled pilot trial. Setting: This trial was conducted at the University of California Davis, Department of Dermatology. Subjects: A total of 31 healthy human subjects were randomized to 3 groups. Interventions: The 3 groups were instructed to take 2,000 mg of either triphala, manjistha or placebo daily for 4 weeks. Outcome Measures: The impact of treatment on gut microbiota composition was evaluated following a 4-week dietary intervention by profiling fecal communities with 16S rRNA profiling in triphala (n = 9), manjistha (n = 9), or placebo (n = 11) treated subjects that completed the intervention. Results: An average of 336 phylotypes were detected in each sample (range: 161 to 648). The analysis of gut microbiota in placebo control and herb-supplemented participants indicated that responses were highly personalized, and no taxa were uniformly altered by the medicinal herb supplementation protocol. Subjects in both treatment groups displayed a trend toward decreased Firmicutes to Bacteroidetes ratio and increased relative abundance of Akkermansia muciniphila. Both medicinal herb treatments reduced the relative abundance of Rikenellaceae, primarily reflecting changes in Alistipes spp. Conclusions: Dietary supplementation with medicinal herbs altered fecal microbial communities. Despite the lack of a clear response signature, a group of bacterial taxa were identified that were more commonly altered in herb-supplemented participants compared to placebo controls. Clinicaltrials.gov identifier NCT03477825.

Effects of Zinc Supplementation on Inflammatory Skin Diseases: A Systematic Review of the Clinical Evidence.

BACKGROUND: Zinc has been used in patients with acne vulgaris for its anti-inflammatory effects; however, it is unclear if zinc supplementation is also beneficial in other inflammatory skin conditions. OBJECTIVE: The objective of this article was to determine the effect of zinc supplementation on inflammatory dermatologic conditions. DATA SOURCES: We searched the Cochrane Central Register of Controlled Trials, EMBASE, MEDLINE, and Ovid with no time limit up to 29 May, 2019. Trials examining supplementation with zinc in the treatment of inflammatory dermatological conditions (acne vulgaris, atopic dermatitis, diaper dermatitis, hidradenitis suppurativa, psoriasis, and rosacea) in children and adults were selected. RESULTS: Of 229 articles, 22 met inclusion criteria. Supplementation with zinc was found to be beneficial in ten of 14 studies evaluating its effects on acne vulgaris, one of two studies on atopic dermatitis, one of one study on diaper dermatitis, and three of three studies evaluating its effects on hidradenitis suppurativa. However, the one article found on psoriasis and the one article found on rosacea showed no significant benefit of zinc treatment on disease outcome. CONCLUSIONS AND IMPLICATIONS: Some preliminary evidence supports the use of zinc in the treatment of acne vulgaris and hidradenitis suppurativa; however, more research is needed with similar methodologies and larger sample sizes in these diseases. Further, zinc may be of some benefit in the treatment plan for atopic dermatitis and diaper dermatitis; however, additional studies should be conducted to further evaluate these potentially positive associations. To date, no evidence is available to suggest that zinc may be of benefit in rosacea and psoriasis; however, limited data are available evaluating the use of zinc in these conditions.

Prospective randomized controlled pilot study on the effects of almond consumption on skin lipids and wrinkles.

OBJECTIVE: Almonds are a rich source of fatty acids and antioxidants, and their supplementation is known to significantly modulate serum lipids. The effects of almond on the skin's lipid barrier and the appearance of wrinkles have not yet been elucidated. The aim of this study was to investigate the effects of almond consumption on facial sebum production and wrinkles. METHODS: This was a prospective, investigator-blinded, randomized controlled trial in which subjects consumed 20% of their daily energy consumption in either almonds or a calorie-matched snack for 16 weeks. This study was completed at the UC Davis Dermatology clinic. Participants were a volunteer sample of generally healthy postmenopausal females with Fitzpatrick skin types 1 and 2. A facial photograph and image analysis system was used to obtain standardized photographs and information on wrinkle width and severity at 0, 8, and 16 weeks. Measurements of transepidermal water loss and sebum production were also completed at 0, 8, and 16 weeks. RESULTS: Fifty healthy postmenopausal females were recruited, 31 participants were enrolled, and 28 completed the study. Under photographic analysis, the almond group had significantly decreased wrinkle severity and width compared with the control group at 16 weeks (p < .02). Changes in skin barrier function were nonsignificant, measured by the transepidermal water loss (p = .65) between the almond and control groups relative to baseline after 16 weeks. No adverse effects were reported. CONCLUSION: Our study demonstrates that daily almond consumption may reduce wrinkle severity in postmenopausal females to potentially have natural antiaging benefits.

Dietary supplementation with turmeric polyherbal formulation decreases facial redness: a randomized double-blind controlled pilot study.

BACKGROUND: Facial redness is multifactorial in nature and may be a sign of many different conditions, including rosacea, photo damage and flushing. Herbal medicines have been used for thousands of years to treat a variety of dermatological conditions. Turmeric (Curcuma longa) and its constituents have been shown to mediate dilation and constriction of peripheral arterioles and have demonstrated anti-oxidant, anti-inflammatory and wound-healing properties. OBJECTIVE: To investigate the effects of turmeric and turmeric-containing polyherbal combination tablets versus placebo on facial redness. DESIGN, SETTING, PARTICIPANTS, AND INTERVENTIONS: This was a prospective, double-blind, randomized pilot study. Thirty-three healthy participants were recruited from the dermatology clinic at the University of California, Davis and nearby community from 2016 to 2017. Thirty participants were enrolled, and 28 participants completed the study. The enrolled participants were randomized to receive one of three interventions (placebo, turmeric or polyherbal combination tablets) and were told to take the intervention tablets by mouth twice daily for 4 weeks. Facial redness was assessed at baseline and 4 weeks after intervention by clinical grading and by image-based analysis. MAIN OUTCOME MEASURES: The primary outcome measure was image-based facial quantification of redness using a research camera and software analysis system. The investigators performed an intention-to-treat analysis by including all subjects who were enrolled in the trial and received any study intervention. Differences were considered statistically significant after accounting for multiple comparisons. Effect sizes for clinical grading were calculated with a Hedges' g where indicated. RESULTS: Twenty-eight participants completed the study and there were no reported adverse events. Based on clinical grading, facial redness intensity and distribution down trended in the polyherbal combination group after 4 weeks (P = 0.1). Under photographic image analysis, the polyherbal combination group had a significant decrease in redness of 40% compared to baseline (P = 0.03). The placebo and turmeric groups had no statistically significant changes in image analysis-based facial redness. CONCLUSION: Polyherbal combination tablet supplementation improved facial redness compared to the turmeric or placebo. Overall, our findings suggested further investigations into the effects of turmeric and polyherbal formulations in skin conditions associated with facial redness would be warranted. TRIAL REGISTRATION: ClinicalTrials.gov identifier: NCT03065504.

Randomized Controlled Pilot Study of Dietary Supplementation with Turmeric or Herbal Combination Tablets on Skin Barrier Function in Healthy Subjects.

To compare the effects of turmeric tablets and turmeric-containing herbal combination tablets versus placebo on skin barrier function and sebum production by measuring facial sebum and transepidermal water loss (TEWL) in healthy subjects. This study was a prospective, double-blinded, rater-blinded, randomized pilot study. Thirty-three generally healthy participants were recruited from the UC Davis Department of Dermatology clinic and the surrounding community from 2016 to 2017, 30 participants were enrolled, and 28 participants completed the study. Thirty individuals were recruited and randomized to the placebo, turmeric, or herbal combination tablet groups. The participants were instructed to take the intervention tablets by mouth twice daily for 4 weeks. Facial sebum production and TEWL were assessed at baseline and 4 weeks. Twenty-eight participants completed the study and there were no adverse events. There were no significant changes in sebum excretion rate in any group after 4 weeks compared with baseline. In the herbal combination tablet group, there was a significant decrease in TEWL (P = .003). No significant changes in TEWL were detected in the turmeric or placebo groups. Turmeric-containing herbal combination tablets significantly decreased TEWL after 4 weeks of twice-daily supplementation. There were no adverse events in any of the three intervention arms. Overall, our findings spark future interest in determining how oral supplementation with herbal formulations may improve skin barrier function and skin appearance, and potentially offer alternative or complementary treatment options.

Medicinal Plant Using Ground State Stabilization of Natural Antioxidant Curcumin by Keto-Enol Tautomerisation.

Curcumin is a medicinal agent that exhibits anti-cancer properties and bioactive pigment in Turmeric has a huge therapeutic value. It has a keto-enol moiety that gives rise to many of its chemical properties. A recent study has shown that keto-enol tautomerisation at this moiety is implicated the effect of curcumin. The tautomerisation of curcumin in methanol, acetone and acetonitrile are used in nuclear magnetic resonance (1H, 13C) spectroscopy. It was characterized using UV, IR and Raman spectral values. The molecular electrostatic potential surface of the Curcumin has been visualized in electropositive potential in the region of the CH3+ group and most electronegative potential in the two oxygen atom has very strong binding group. In the following, the modality of structural and thermo dynamical parameters, electrophilicity (ω), chemical potential (µ), chemical hardness (η) and electronic charge transfer confirms the local reactivity. The rate constant of tautomerisation of curcumin shows strong temperature dependence. Molecular electrostatic potential and Temperature dependence of various thermodynamic properties like [Formula: see text] is increase with increase in temperature for monomer and dimer of various electrical fields.

Emerging Therapies for Acne Vulgaris.

As we gain a greater understanding of acne pathogenesis, both new agents as well as new uses for established drugs are being considered for the treatment of acne vulgaris. Multiple clinical trials assessing new formulations or combinations of established acne treatments have been conducted, and novel uses of antimicrobials such as modified diallyl disulfide oxide and nitric oxide are being assessed in clinical trials. There are also a multitude of new therapies currently being studied that target the inflammatory cascade of acne pathogenesis, including sebosuppressive and anti-inflammatory phytochemicals, and  small molecule inhibitors targeting sebaceous glands and enzymes, among others. Laser and light therapy is also being modified for the treatment of acne through combination methods with metal nanoshells and vacuum assistance. Probiotics have gained popularity in medicine as greater knowledge of the microbiome and its effects on multiple organ systems is being elucidated. Studies describing the positive effects of certain ammonia-oxidizing bacterial strains in the regulation of the skin's inflammatory response are ongoing. Therapies for acne are constantly evolving and current gold-standard acne therapy may be supplemented with novel treatment modalities in the near future.

Natural Oils for Skin-Barrier Repair: Ancient Compounds Now Backed by Modern Science.

Natural plant oils are commonly used as topical therapy worldwide. They are usually easily accessible and are relatively inexpensive options for skin care. Many natural oils possess specific compounds with antimicrobial, antioxidant, anti-inflammatory, and anti-itch properties, making them attractive alternative and complementary treatments for xerotic and inflammatory dermatoses associated with skin-barrier disruption. Unique characteristics of various oils are important when considering their use for topical skin care. Differing ratios of essential fatty acids are major determinants of the barrier repair benefits of natural oils. Oils with a higher linoleic acid to oleic acid ratio have better barrier repair potential, whereas oils with higher amounts of irritating oleic acid may be detrimental to skin-barrier function. Various extraction methods for oils exist, including cold pressing to make unrefined oils, heat and chemical distillation to make essential oils, and the addition of various chemicals to simulate a specific scent to make fragranced oils. The method of oil processing and refinement is an important component of selecting oil for skin care, and cold pressing is the preferred method of oil extraction as the heat- and chemical-free process preserves beneficial lipids and limits irritating byproducts. This review summarizes evidence on utility of natural plant-based oils in dermatology, particularly in repairing the natural skin-barrier function, with the focus on natural oils, including Olea europaea (olive oil), Helianthus annus (sunflower seed oil), Cocos nucifera (coconut oil), Simmondsia chinesis (jojoba oil), Avena sativa (oat oil), and Argania spinosa (argan oil).
