Abstract
A healthy and balanced diet is an important factor to assure a good functioning of the central and peripheral nervous system. Retinoid X receptor (RXR)-mediated signaling was identified as an important mechanism of transmitting major diet-dependent physiological and nutritional signaling such as the control of myelination and dopamine signalling. Recently, vitamin A5/X, mainly present in vegetables as provitamin A5/X, was identified as a new concept of a vitamin which functions as the nutritional precursor for enabling RXR-mediated signaling. The active form of vitamin A5/X, 9-cis-13,14-dehydroretinoic acid (9CDHRA), induces RXR-activation, thereby acting as the central switch for enabling various heterodimer-RXR-signaling cascades involving various partner heterodimers like the fatty acid and eicosanoid receptors/peroxisome proliferator-activated receptors (PPARs), the cholesterol receptors/liver X receptors (LXRs), the vitamin D receptor (VDR), and the vitamin A(1) receptors/retinoic acid receptors (RARs). Thus, nutritional supply of vitamin A5/X might be a general nutritional-dependent switch for enabling this large cascade of hormonal signaling pathways and thus appears important to guarantee an overall organism homeostasis. RXR-mediated signaling was shown to be dependent on vitamin A5/X with direct effects for beneficial physiological and neuro-protective functions mediated systemically or directly in the brain. In summary, through control of dopamine signaling, amyloid β-clearance, neuro-protection and neuro-inflammation, the vitamin A5/X - RXR - RAR - vitamin A(1)-signaling might be "one of" or even "the" critical factor(s) necessary for good mental health, healthy brain aging, as well as for preventing drug addiction and prevention of a large array of nervous system diseases. Likewise, vitamin A5/X - RXR - non-RAR-dependent signaling relevant for myelination/re-myelination and phagocytosis/brain cleanup will contribute to such regulations too. In this review we discuss the basic scientific background, logical connections and nutritional/pharmacological expert recommendations for the nervous system especially considering the ageing brain.

Abstract
With the improvement of living quality, people pay more and more attention to vitamin supplements. The vitamins in the daily diet can meet the needs of the body. Whether additional vitamin supplementation is necessary still needs to be further explored. Many studies have reported that vitamin deficiency and excessive vitamin supplementation could lead to abnormal development in the body or increase the risk of diseases. Here, we summarize the abnormal levels of vitamins can cause the homeostasis imbalance of hypothalamus-pituitary-adrenal (HPA) axis by affecting its development and function. It can lead to abnormal synthesis and secretion of glucocorticoid in the body, which mediates the occurrence and development of metabolic diseases and psychoneurotic diseases. In addition, vitamin has a strong antioxidant effect, which can eliminate oxygen free radicals. Thereby, vitamins can alter HPA axis function and homeostasis maintenance by combating oxidative stress. This review provides a theoretical basis for clarifying the role of abnormal levels of vitamin in the occurrence and development of multiple diseases and its intervention strategy, and also provides reference value and guiding significance for rational use of vitamins.

Abstract
Retinol is a fat-soluble vitamin that plays an essential role in many biological processes throughout the human lifespan. Here, we perform the largest genome-wide association study (GWAS) of retinol to date in up to 22,274 participants. We identify eight common variant loci associated with retinol, as well as a rare-variant signal. An integrative gene prioritisation pipeline supports novel retinol-associated genes outside of the main retinol transport complex (RBP4:TTR) related to lipid biology, energy homoeostasis, and endocrine signalling. Genetic proxies of circulating retinol were then used to estimate causal relationships with almost 20,000 clinical phenotypes via a phenome-wide Mendelian randomisation study (MR-pheWAS). The MR-pheWAS suggests that retinol may exert causal effects on inflammation, adiposity, ocular measures, the microbiome, and MRI-derived brain phenotypes, amongst several others. Conversely, circulating retinol may be causally influenced by factors including lipids and serum creatinine. Finally, we demonstrate how a retinol polygenic score could identify individuals more likely to fall outside of the normative range of circulating retinol for a given age. In summary, this study provides a comprehensive evaluation of the genetics of circulating retinol, as well as revealing traits which should be prioritised for further investigation with respect to retinol related therapies or nutritional intervention.

Abstract
Acne is a chronic inflammatory disease of the pilosebaceous unit with a multifactorial etiology and is one of the most common conditions treated by dermatologists and primary care physicians. Within an extensive and evolving treatment landscape, oral isotretinoin has demonstrated efficacy for treatment of severe, recalcitrant acne. Several side effects of isotretinoin have been reported, including laboratory abnormalities, mucocutaneous, and musculoskeletal effects, which may reduce compliance and patient satisfaction with treatment. In this narrative review, we aim to review the efficacy and safety profile of oral supplements or topical adjuvant therapies in mitigating isotretinoin-associated mucocutaneous and musculoskeletal side effects. Oral supplements reviewed include omega-3 fatty acids, vitamin E, folic acid and vitamin B12, antihistamines, l-carnitine, biotin, and combined oral supplements. Topical adjuvants include a hyaluronic acid, biosaccharide gum-2, and glycerine gel-cream; a nongreasy, noncomedogenic, fragrance-free moisturizing cream; dexpanthenol; trichloroacetic acid; and a combination cream. Most of the supplements and topical adjuvants demonstrated efficacy with an adequate level of supporting evidence and no reported adverse events, indicating an adequate safety profile. Patients on isotretinoin may benefit from using oral supplements and topical adjuvants to minimize primarily mucocutaneous side effects, increase adherence to treatment, and thereby improve overall outcomes.

Abstract
Importance While acne is common in transgender and gender-diverse people and is associated with gender-affirming hormone therapy, little research has examined these factors and their impact in gender minority groups. Objective To examine the lived experiences of acne and acne treatment in transgender and gender-diverse participants. Design, Setting, and Participants This mixed-methods analysis was conducted at a multidisciplinary gender center at a public safety-net hospital and endocrinology and dermatology clinics at a tertiary academic center from January 4, 2021, to April 7, 2022, using semistructured interviews and surveys. Participants were transgender or gender-diverse adults who had received gender-affirming hormone therapy. Data analysis was performed from November 11, 2021, to March 31, 2023. Exposure Current diagnosis of acne. Main Outcomes and Measures Interviews exploring the experience of acne and acne treatment were audio recorded, transcribed verbatim, coded using minority stress theory and the socioecological model, and analyzed using thematic analysis. Themes were triangulated with survey data on gender, self-reported acne severity, skin-specific quality-of-life impact, and treatment experience. Results A total of 32 participants were included in the study (mean [range] age, 32 [18-57] years; 17 transgender men, 11 transgender women, and 4 nonbinary participants). Ten participants (31%) self-rated their skin as currently clear or almost clear, 11 (34%) reported mild acne, and 11 (34%) had moderate to severe acne. Participants described experiences of rejection and bullying related to acne and admitted avoiding social interactions in which they anticipated acne-related discrimination, which led to feelings of depression and anxiety. Acne worsened body appearance dissatisfaction. Transgender women reported acne interfering with feminine gender expression. Transgender men often normalized acne development, sometimes viewing acne positively as an early sign of testosterone action. Most participants tried over-the-counter acne treatments and commonly sought acne treatment advice from physicians, peers, online forums, and social media. Barriers to acne treatments included cost, lack of multidisciplinary care, mistrust toward the health care system, and lack of transgender-specific acne care education. Conclusions and Relevance In this mixed-methods study, transgender and gender-diverse individuals reported experiencing acne-related stigma and facing barriers to acne treatment. Multilevel changes, such as developing strategies to reduce acne stigma, providing transgender-specific acne care education, facilitating multidisciplinary acne care, and expanding transgender-friendly clinical environments, are recommended to reduce the impact of acne in transgender individuals.

Abstract
The ongoing COVID-19 pandemic has revealed the shortfalls in our understanding of how to treat coronavirus infections. With almost 7 million case fatalities of COVID-19 globally, the catalog of FDA-approved antiviral therapeutics is limited compared to other medications, such as antibiotics. All-trans retinoic acid (RA), or activated vitamin A, has been studied as a potential therapeutic against coronavirus infection because of its antiviral properties. Due to its impact on different signaling pathways, RA's mechanism of action during coronavirus infection has not been thoroughly described. To determine RA's mechanism of action, we examined its effect against a mouse coronavirus, mouse hepatitis virus strain A59 (MHV). We demonstrated that RA significantly decreased viral titers in infected mouse L929 fibroblasts and RAW 264.7 macrophages. The reduced viral titers were associated with a corresponding decrease in MHV nucleocapsid protein expression. Using interferon regulatory factor 3 (IRF3) knockout RAW 264.7 cells, we demonstrated that RA-induced suppression of MHV required IRF3 activity. RNA-seq analysis of wildtype and IRF3 knockout RAW cells showed that RA upregulated calcium/calmodulin (CaM) signaling proteins, such as CaM kinase kinase 1 (CaMKK1). When treated with a CaMKK inhibitor, RA was unable to upregulate IRF activation during MHV infection. In conclusion, our results demonstrate that RA-induced protection against coronavirus infection depends on IRF3 and CaMKK.

Abstract
Importance Isotretinoin is hypothesized to contribute to the development of psychiatric disorders, but the epidemiological association and risk factors associated with psychiatric disorders among isotretinoin users remain unclear. Objective To clarify the absolute and relative risk and risk factors associated with suicide and psychiatric disorders among isotretinoin users. Data Sources PubMed, Embase, Web of Science, and Scopus were searched from inception until January 24, 2023. Study Selection Randomized trials and observational studies were selected if they reported the absolute risk, relative risk, and risk factors for suicide and psychiatric disorders among isotretinoin users. Data Extraction and Synthesis Relevant data were extracted and risk of bias was evaluated at the study level using the Newcastle-Ottawa Scale. Data were pooled using inverse variance-weighted meta-analyses. Heterogeneity was measured using the I2 statistic, and meta-regression analyses were performed. Main Outcomes and Measures Absolute risk (percentage), relative risks (risk ratios [RR]), and risk factors (RR) of suicide and psychiatric disorders among isotretinoin users. Results A total of 25 studies including 1 625 891 participants were included in the review and 24 in the meta-analysis. Among the included studies, participants' average age ranged from 16 to 38 years, and distribution by sex ranged from 0% to 100% male. The 1-year pooled absolute risk from between 2 and 8 studies of completed suicide, suicide attempt, suicide ideation, and self-harm were each less than 0.5%, while that of depression was 3.83% (95% CI, 2.45-5.93; I2 = 77%) in 11 studies. Isotretinoin users were less likely than nonusers to attempt suicide at 2 years (RR, 0.92; 95% CI, 0.84-1.00; I2 = 0%), 3 years (RR, 0.86; 95% CI, 0.77-0.95; I2 = 0%), and 4 years (RR, 0.85; 95% CI, 0.72-1.00; I2 = 23%) following treatment. Isotretinoin was not associated with the risk of all psychiatric disorders (RR, 1.08; 95% CI, 0.99-1.19; I2 = 0%). Study-level meta-regression found that studies with participants of older age reported lower 1-year absolute risk of depression, while those with a higher percentage of male participants reported a higher 1-year absolute risk of completed suicide. Conclusions and Relevance The findings suggest that at a population level, isotretinoin users do not have increased risk of suicide or psychiatric conditions but may instead have a lower risk of suicide attempts at 2 to 4 years following treatment. While these findings are reassuring, clinicians should continue to practice holistic psychodermatologic care and monitor patients for signs of mental distress during isotretinoin treatment.

Abstract
Background and Objectives: Serum vitamin levels, cardiovascular disease risk factors, and their association with depression is a complex issue that has been the subject of much research. Therefore, we investigated the relationship between vitamin A, B9, and E levels, cardiovascular risk factors, and depression in premenopausal and menopausal South Korean women. Materials and Methods: This cross-sectional study used the 2016-2018 Korea National Health and Nutrition Examination Survey data. Depression was assessed using a questionnaire to check for symptoms of depression or the Patient Health Questionnaire-9. Blood samples were collected from the antecubital vein in the morning after an overnight fast. Covariates were defined as self-reported physician diagnoses. Well-trained medical staff performed the standard procedures. Statistical analysis was performed using the complex sample analysis method of SPSS, using two separate logistic regression models (model 1: adjusted for age; model 2: adjusted for age, marital status, smoking, and alcohol consumption). Results: A total of 3313 women aged over 20 years were enrolled. The association between vitamin A levels and depression was as follows: lower levels of vitamin A were associated with an increased risk of depression in premenopausal women in model 1 and model 2. The levels of serum vitamins E and B9 were not correlated with depression in premenopausal and postmenopausal women. In the premenopausal group, depression increased in the obesity (model 1: p = 0.037; model 2: p = 0.047) and diabetes mellitus (model 1: p = 0.010; model 2: p = 0.009) groups. The menopausal group with depression had higher rates of stroke (model 1: p = 0.017; model 2: p = 0.039) and myocardial infarction (model 1: p = 0.004; model 2: p = 0.008) than the group without depression. Conclusions: Depression is correlated with lower blood levels of vitamin A in premenopausal women. Vitamin B9 and E levels were not associated with depression independent of menopausal status. Depression is associated with obesity and diabetes mellitus in premenopausal women and with stroke and myocardial infarction in postmenopausal women.

Abstract
Medulloblastoma (MB) is a malignant tumor of the cerebellum that occurs in children and infants. Abnormal neuronal differentiation can lead to brain tumors, and topoisomerase IIβ (Top IIβ) plays an important role in neuronal differentiation. The aim of this study was to investigate the molecular mechanism of 13-cis retinoic acid (13-cis RA) promoting the expression of Top IIβ and inducing neuronal differentiation in human MB Daoy cells. The results showed that 13-cis RA inhibited the cell proliferation and induced cell cycle arrest in G0/G1 phase. The cells differentiated into a neuronal phenotype, with high expression of the neuronal marker microtubule-associated protein 2 (MAP2) and abundant Top IIβ, and obvious neurite growth. Chromatin immunoprecipitation (ChIP) assay showed that histone H3 lysine 27 tri-methylation (H3K27me3) modification in Top IIβ promoter decreased after 13-cis RA-induced cell differentiation, while jumonji domain-containing protein 3 (JMJD3) binding in Top IIβ promoter increased. These results suggest that H3K27me3 and JMJD3 can regulate the expression of Top IIβ gene, which is related to inducing neural differentiation. Our results provide new insights into understanding the regulatory mechanisms of Top IIβ during neuronal differentiation and imply the potential application of 13-cis RA in the clinical treatment of MB.

[PMID: 38098868 PMCID: PMC10720671 DOI: 10.3389/fendo.2023.1271521] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/02/2023] [Accepted: 11/17/2023] [Indexed: 12/17/2023] Open
Abstract
Oxidative stress, resulting from dysregulation in the secretion of adrenal hormones, represents a major concern in human health. The present review comprehensively examines various categories of endocrine dysregulation within the adrenal glands, encompassing glucocorticoids, mineralocorticoids, and androgens. Additionally, a comprehensive account of adrenal hormone disorders, including adrenal insufficiency, Cushing's syndrome, and adrenal tumors, is presented, with particular emphasis on their intricate association with oxidative stress. The review also delves into an examination of various nutritional antioxidants, namely vitamin C, vitamin E, carotenoids, selenium, zinc, polyphenols, coenzyme Q10, and probiotics, and elucidates their role in mitigating the adverse effects of oxidative stress arising from imbalances in adrenal hormone levels. In conclusion, harnessing the power of nutritional antioxidants has the potential to help with oxidative stress caused by an imbalance in adrenal hormones. This could lead to new research and therapeutic interventions.

Abstract
Metabolome reflects the interplay of genome and exposome at molecular level and thus can provide deep insights into the pathogenesis of a complex disease like major depression. To identify metabolites associated with depression we performed a metabolome-wide association analysis in 13,596 participants from five European population-based cohorts characterized for depression, and circulating metabolites using ultra high-performance liquid chromatography/tandem accurate mass spectrometry (UHPLC/MS/MS) based Metabolon platform. We tested 806 metabolites covering a wide range of biochemical processes including those involved in lipid, amino-acid, energy, carbohydrate, xenobiotic and vitamin metabolism for their association with depression. In a conservative model adjusting for life style factors and cardiovascular and antidepressant medication use we identified 8 metabolites, including 6 novel, significantly associated with depression. In individuals with depression, increased levels of retinol (vitamin A), 1-palmitoyl-2-palmitoleoyl-GPC (16:0/16:1) (lecithin) and mannitol/sorbitol and lower levels of hippurate, 4-hydroxycoumarin, 2-aminooctanoate (alpha-aminocaprylic acid), 10-undecenoate (11:1n1) (undecylenic acid), 1-linoleoyl-GPA (18:2) (lysophosphatidic acid; LPA 18:2) are observed. These metabolites are either directly food derived or are products of host and gut microbial metabolism of food-derived products. Our Mendelian randomization analysis suggests that low hippurate levels may be in the causal pathway leading towards depression. Our findings highlight putative actionable targets for depression prevention that are easily modifiable through diet interventions.

Abstract
INTRODUCTION Isotretinoin is an effective drug widely used in the treatment of severe acne. In this study, we tried to evaluate the incidence of anal fissures with clinical and laboratory side effects associated with isotretinoin. METHODS The study evaluated 210 patients who received systemic isotretinoin treatment. Especially patients with constipation and anal bleeding were evaluated by the General Surgery clinic to arrange appropriate treatments. RESULTS Of 210 patients included in the study, 138 (65.7%) were female and 72 (34.3%) were male, with a mean age of 23.7 years. The most common adverse event was dry lips in 206 (98.1%) patients. The mucocutaneous side effects were constipation 36 (17.1%), anal bleeding 18 (8.6%), mucosal erosion 10 (4.7%), anal fissure 7 (3.3%). Treatment was discontinued due to elevated liver function tests in 5 patients (2.3%), and because anal bleeding could not be controlled in 1 patient. CONCLUSIONS Isotretinoin is the most effective acne medicine used today. Clarification of the patients about the rarely seen side effects such as dryness, erosion, fissure and bleeding in the anal mucosa in addition to the common mucocutaneous side effects will ensure that patients are more cautious and increase their tolerance to the treatment.

Abstract
INTRODUCTION Risk of inflammatory bowel disease under isotretinoin is a scope of a long-standing controversy. The burden of isotretinoin-related irritable bowel syndrome has not been investigated. OBJECTIVE To evaluate the risk of Crohn's disease, ulcerative colitis (UC), and irritable bowel syndrome in patients with acne starting isotretinoin vs oral antibiotics treatment. METHODS A global population-based retrospective cohort study assigned 2 groups of patients with acne initiating isotretinoin (n = 77,005) and oral antibiotics (n = 77,005). Comprehensive propensity-score matching was conducted. RESULTS The lifetime risk of Crohn's disease (hazard ratio [HR], 1.05; 95% CI, 0.89-1.24; P = .583) and UC (HR, 1.13; 95% CI, 0.95-1.34; P = .162) was comparable between study groups, whereas the lifetime risk of irritable bowel syndrome was lower in isotretinoin-prescribed patients (HR, 0.82; 95% CI, 0.76-0.89; P < .001). In time-stratified analysis, isotretinoin-related risk of UC was significantly increased during the first 6 months following drug initiation (HR, 1.93; 95% CI, 1.29-2.88; P = .001), but decreased afterward to level the risk of the comparator group. The absolute risk difference within the first 6 months was clinically marginal (5.0 additional UC cases/10,000 patients starting isotretinoin; 95% CI, 2.5-7.7). LIMITATIONS Retrospective data collection. CONCLUSION Isotretinoin does not confer an elevated risk of Crohn's disease, whilst it might be associated with a slight and transient increase in UC risk.

Abstract
BackgroundDespite a growing body of evidence that acne impacts mental disorders, the actual causality has not been established for the possible presence of recall bias and confounders in observational studies.MethodsWe performed a two-sample Mendelian randomization (MR) analysis to evaluate the effect of acne on the risk of six common mental disorders, i.e., depression, anxiety, schizophrenia, obsessive–compulsive disorder (OCD), bipolar disorder, and post-traumatic stress disorder (PTSD). We acquired genetic instruments for assessing acne from the largest genome-wide association study (GWAS) of acne (N = 615,396) and collected summary statistics from the largest available GWAS for depression (N = 500,199), anxiety (N = 17,310), schizophrenia (N = 130,644), OCD (N = 9,725), bipolar disorder (N = 413,466), and PTSD (N = 174,659). Next, we performed the two-sample MR analysis using four methods: inverse-variance weighted method, MR-Egger, weighted median, and MR pleiotropy residual sum and outliers. Sensitivity analysis was also performed for heterogeneity and pleiotropy tests.ResultsThere was no evidence of a causal impact of acne on the risk of depression [odds ratio (OR): 1.002, p = 0.874], anxiety (OR: 0.961, p = 0.49), OCD (OR: 0.979, p = 0.741), bipolar disorder (OR: 0.972, p = 0.261), and PTSD (OR: 1.054, p = 0.069). Moreover, a mild protective effect of acne against schizophrenia was observed (OR: 0.944; p = 0.033).ConclusionThe increased prevalence of mental disorders observed in patients with acne in clinical practice was caused by modifiable factors, and was not a direct outcome of acne. Therefore, strategies targeting the elimination of potential factors and minimization of the occurrence of adverse mental events in acne should be implemented.

Toxicology 2023; 487:153461.

Abstract
Cyanobacterial blooms are known sources of environmentally-occurring retinoid compounds, including all-trans and 9-cis retinoic acids (RAs). The developmental hazard for aquatic organisms has been described, while the implications for human health hazard assessment are not yet sufficiently characterized. Here, we employ a human neural stem cell model that can differentiate in vitro into a mixed culture of neurons and glia. Cells were exposed to non-cytotoxic 8-1000 nM all-trans or 9-cis RA for 9-18 days (DIV13 and DIV22, respectively). Impact on biomarkers was analyzed on gene expression (RT-qPCR) and protein level (western blot and proteomics) at both time points; network patterning (immunofluorescence) on DIV22. RA exposure significantly concentration-dependently increased gene expression of retinoic acid receptors and the metabolizing enzyme CYP26A1, confirming the chemical-specific response of the model. Expression of thyroid hormone signaling-related genes remained mostly unchanged. Markers of neural progenitors/stem cells (PAX6, SOX1, SOX2, NESTIN) were decreased with increasing RA concentrations, though a basal population remained. Neural markers (DCX, TUJ1, MAP2, NeuN, SYP) remained unchanged or were decreased at high concentrations (200-1000 nM). Conversely, (astro-)glial marker S100β was increased concentration-dependently on DIV22. Together, the biomarker analysis indicates an RA-dependent promotion of glial cell fates over neural differentiation, despite the increased abundance of neural protein biomarkers during differentiation. Interestingly, RA exposure induced substantial changes to the cell culture morphology: while low concentrations resulted in a network-like differentiation pattern, high concentrations (200-1000 nM RA) almost completely prevented such network patterning. After functional confirmation for implications in network function, such morphological features could present a proxy for network formation assessment, an apical key event in (neuro-)developmental Adverse Outcome Pathways. The described application of a human in vitro model for (developmental) neurotoxicity to emerging environmentally-relevant retinoids contributes to the evidence-base for the use of differentiating human in vitro models for human health hazard and risk assessment.

Abstract
Depression has a multifactorial etiology comprising family history and unemployment. This review aims to summarize the evidence available for the antioxidant and anti-inflammatory effects of carotenoids in mood disorders. This review article’s methodologies were based on a search of the PubMed database for all linked published papers. Epidemiological studies indicate that a diet rich in vegetables, fruits, nuts, fish, and olive oil may prevent the development of depression. Antioxidant supplementation has been found to combat various stress-induced psychiatric disorders, including depression and anxiety. A growing body of evidence indicates that carotenoids have both antioxidant and anti-inflammatory. Studies also suggest that poor dietary intake, particularly low intakes of fruit and vegetables and high intakes of fast food and other convenience foods, may increase the risk of developing depression. Thus, dietary interventions have the potential to help mitigate the risk of mental health decline in both the general population and those with mood disorders. Considering that carotenoids have both antioxidant and anti-inflammatory effects, it is expected that they might exert a promising antidepressant effect. Nevertheless, further studies (including interventional and mechanistic studies) assessing the effect of carotenoids on preventing and alleviating depression symptoms are needed.

Abstract
Pityriasis rubra pilaris represents a group of familial and acquired disorders of cornification that affect both adult and pediatric patients. Treatment options are difficult to assess through clinical trials, given the rarity of the disorder and its tendency for spontaneous remission. Case reports and case series are therefore the primary means of assessment. Because of the heterogeneity of the disease, there is no universal approach to treatment, and multiple agents may need to be trialed to achieve disease control. At present, topicals are used for most pediatric patients, though monotherapy with topicals is only effective for less severe disease. Despite concerns over their side-effect profiles, oral retinoids are generally accepted as a first-line systemic therapy. However, interleukin-17 inhibitors and ustekinumab, an interleukin-12 and interleukin-23 inhibitor, may soon become first-line systemic treatment as well, given their efficacy and relative safety in trials thus far. Ustekinumab, in particular, is emerging as a first-line agent for patients with pityriasis rubra pilaris with CARD14 gene variations. When these therapies fail, second-line and adjunctive therapies to consider include tumor necrosis factor-alpha inhibitors, methotrexate, and phototherapy. However, further investigation is necessary to assess the safety and efficacy of many of these agents in juvenile pityriasis rubra pilaris.

Abstract
The small, hormone-like molecule retinoic acid (RA) is a vital regulator in several neurobiological processes that are affected in depression. Next to its involvement in dopaminergic signal transduction, neuroinflammation, and neuroendocrine regulation, recent studies highlight the role of RA in homeostatic synaptic plasticity and its link to neuropsychiatric disorders. Furthermore, experimental studies and epidemiological evidence point to the dysregulation of retinoid homeostasis in depression. Based on this evidence, the present study investigated the putative link between retinoid homeostasis and depression in a cohort of 109 patients with major depressive disorder (MDD) and healthy controls. Retinoid homeostasis was defined by several parameters. Serum concentrations of the biologically most active Vitamin A metabolite, all-trans RA (at-RA), and its precursor retinol (ROL) were quantified and the individual in vitro at-RA synthesis and degradation activity was assessed in microsomes of peripheral blood-derived mononuclear cells (PBMC). Additionally, the mRNA expression of enzymes relevant to retinoid signaling, transport, and metabolism were assessed. Patients with MDD had significantly higher ROL serum levels and greater at-RA synthesis activity than healthy controls providing evidence of altered retinoid homeostasis in MDD. Furthermore, MDD-associated alterations in retinoid homeostasis differed between men and women. This study is the first to investigate peripheral retinoid homeostasis in a well-matched cohort of MDD patients and healthy controls, complementing a wealth of preclinical and epidemiological findings that point to a central role of the retinoid system in depression.

Abstract
Purpose. Study the effects of 13-cis-retinoic acid (13-RA), a synthetic analogue of a vitamin A used for the treatment of severe acne, on the blood flow in the rat brain using technetium-99m hexamethyl propylene amine oxime (99mTc-HMPAO) imaging. Methods. A total of 30 adult male Wistar rats were divided into the control (C), low-dose (L), and high-dose (H) groups. The L and H rats were exposed subcutaneously to 0.3 and 0.5 mg, respectively, of 13-RA per kg of body weight for seven days. Brain blood flow imaging was performed using a gamma camera. Then, a region of interest (ROI) around the brain (target, T), a whole-body region (WB), and a background region (BG) was selected and delimited. The net 99mTc-HMPAO brain counts were calculated as the net target counts,
in all groups. At the end of the 99mTc-HMPAO brain blood flow imaging, the brain, heart, kidney, lung, and liver were rapidly removed, and their uptake was determined. Brain histopathological analysis was performed using hematoxylin and eosin stains. In addition, the plasma fatty acids were studied using gas chromatography/mass spectrometry. Results. There were highly significant differences between L and H in comparison to C and across the groups. The 99mTc-HMPAO radioactivity in the brain showed increased uptake in a dose-dependent manner. There were also significant changes in the brain tissues and decreased free fatty acids among the groups compared to C. Conclusion. 13-RA increases 99mTcHMPAO brain perfusion, uptake, and function and reduces fatty acids.

Abstract
Choroidal neovascularization (CNV) is a typical pathological feature of neovascular age-related macular degeneration and has become a major cause of vision loss in the elderly. Current therapies require repeated intraocular injections of anti-VEGF drugs by inhibiting endothelial angiogenic effects, which is painful and may cause adverse effects on normal vascular and neuronal functions. Herein, we designed a novel retinoid drug, EYE-101, determined its therapeutic effects on CNV, and clarified the anti-angiogenic mechanism. The results show that administration of EYE-101 did not cause obvious cytotoxicity and ocular tissue toxicity at the concentrations less than 5 μM. Topical administration of EYE-101 could reduce choroidal sprouting, suppress laser-induced CNV formation, and decrease pericyte coverages on ocular vessels. Administration of EYE-101 also suppressed endothelial cell proliferation, migration, and tube formation and reduced pericyte proliferation, migration, recruitment towards endothelial cells. EYE-101 exerted its anti-angiogenic effects by targeting endothelial cells and pericytes via antagonizing Wnt/β-catenin signaling and PDGF signaling. Thus, EYE-101 administration may offer an"one stone and two birds" strategy for the prevention and treatment of ocular neovascular disorders.

Abstract
INTRODUCTION Isotretinoin-related risk of depression and suicidal behavior is a topic of inconclusiveness. A crucial knowledge gap exists in defining the association of isotretinoin with other psychiatric comorbidities. OBJECTIVE To evaluate the risk of psychiatric outcomes among patients with acne treated with isotretinoin versus oral antibiotics. METHODS A global population-based retrospective cohort study enrolled 2 groups of patients with acne managed by isotretinoin (n = 75,708) and oral antibiotics (n = 75,708). Patients were compared regarding the risk of 9 psychiatric outcomes. RESULTS Relative to those treated with oral antibiotics, patients prescribed isotretinoin experienced lower risk of depression (hazard ratio [HR], 0.90; 95% confidence interval [CI], 0.87-0.93; P < .001), but comparable risk of major depressive disorder (HR, 0.97; 95% CI, 0.92-1.03; P = .318). Risk of suicidal attempts was comparable between groups (HR, 0.97; 95% CI, 0.85-1.11; P = .663), despite the elevated risk of suicidal ideation in those under isotretinoin (HR, 1.41; 95% CI, 1.32-1.50; P < .001). Patients under isotretinoin had lower risk of post-traumatic stress disorder (HR, 0.75; 95% CI, 0.68-0.82; P < .001), anxiety (HR, 0.84; 95% CI, 0.82-0.87; P < .001), bipolar disorder (HR, 0.65; 95% CI, 0.59-0.72; P < .001), schizophrenia (HR, 0.60; 95% CI, 0.48-0.76; P < .001), and adjustment disorder (HR, 0.82; 95% CI, 0.77-0.87; P < .001). LIMITATIONS Retrospective data collection. CONCLUSION Isotretinoin confers lower risk of 6 psychiatric comorbidities and comparable risk of suicidal attempts.

Abstract
Acne vulgaris is one of the commonest inflammatory skin diseases seen worldwide, affecting all ethnicities and races, with a peak prevalence between age 15 years and 20 years. The burden of this condition, and the resulting clinical and psychological sequelae, is substantial. The visual appearance of acne and its sequelae, including scarring and pigment changes, frequently results in psychological and social morbidity because of concerns about appearance. As understanding of the pathophysiology has evolved, approaches to achieving the optimal outcomes with effective treatment regimens continue to emerge. In the past few years, several novel therapeutics have been developed, including new agents aimed at reducing antimicrobial resistance and products with specific actions targeting retinoid receptors and androgen receptors. This Review considers the management approaches of an adolescent with acne vulgaris and reviews treatment options from the evidence base and international expert opinion. Approaches to selecting current treatments and novel and emerging treatment regimens are discussed.

Abstract
OBJECTIVE A healthy and stable microbiome has many beneficial effects on the host, while an unbalanced or disordered microbiome can lead to various skin diseases. Hyaluronic acid is widely used in the cosmetics and pharmaceutical industries; however, specific reports on its effect on the skin microflora of healthy people have not been published. This study aimed to determine the effect of sodium hyaluronate on the facial microflora of healthy individuals. METHODS Face of 20 healthy female volunteers between 18 and 24 years was smeared with sodium hyaluronate solution once per day. Cotton swabs were used to retrieve samples on days 0, 14, and 28, and high-throughput sequencing of 16 S rRNA was used to determine the changes in bacterial community composition. RESULTS Facial application of HA can reduce the abundance of pathogenic bacteria, such as Cutibacterium and S. aureus, and increase the colonization of beneficial bacteria. CONCLUSION This is the first intuitive report to demonstrate the effect of hyaluronic acid on facial microflora in healthy people. Accordingly, sodium hyaluronate was found to have a positive effect on facial skin health.

Abstract
In this review, we discuss the emerging role of Cellular Retinoic Acid Binding Protein 1 (CRABP1) as a mediator of non-canonical activities of retinoic acid (RA) and relevance to human diseases. We first discuss the role of CRABP1 in regulating MAPK activities and its implication in stem cell proliferation, cancers, adipocyte health, and neuro-immune regulation. We then discuss an additional role of CRABP1 in regulating CaMKII activities, and its implication in heart and motor neuron diseases. Through molecular and genetic studies of Crabp1 knockout (CKO) mouse and culture models, it is established that CRABP1 forms complexes with specific signaling molecules to function as RA-regulated signalsomes in a cell context-dependent manner. Gene expression data and CRABP1 gene single nucleotide polymorphisms (SNPs) of human cancer, neurodegeneration, and immune disease patients implicate the potential association of abnormality in CRABP1 with human diseases. Finally, therapeutic strategies for managing certain human diseases by targeting CRABP1 are discussed.

Abstract
Little is known about associations between depression and serum heavy metal levels, dietary vitamin intakes. Thus, we sought to determine the nature of these associations and to predict risks of depression using marginal effects. A data set of 16,371 individuals aged ≥10 years that participated in Korea National Health and Nutrition Examination Surveys (KNHANES) conducted from 2009 to 2017 (excluding 2014 and 2015) was used to obtain information on sociodemographics, family histories, lifestyles, serum heavy metal levels, food intakes, and depression. Serum cadmium (Cd) and lead (Pb) levels were analyzed by graphite furnace atomic absorption spectrometry and mercury (Hg) levels using a mercury analyzer. Daily vitamin intakes were calculated by 24-h dietary recall. The results obtained showed that females are at higher risk of depression than males. A doubling of serum Cd was associated with a 21% increase in depression (AOR 1.21, 95% CI: 1.07-1.37, p = 0.002), whereas twofold increases in daily vitamin B1, B3 and vitamin A intakes reduced the risk of depression by 17% (0.83, 95% CI: 0.73-0.95, p = 0.005), 20% (0.80, 95% CI: 0.70-0.91, p = 0.001), and 8% (0.92, 95% CI: 0.85-0.99, p = 0.020), respectively. Interactions between heavy metals, vitamin intakes, and sex did not influence the risk of depression. The result shows that increased daily dietary vitamin intake might protect the public against depression. Further studies are needed to reduce the risks posed by heavy metals and to determine more comprehensively the effects of daily dietary vitamin intake on depression.

Abstract
BACKGROUND After isotretinoin's approval to treat patients with recalcitrant acne, there have been continued debates around its psychiatric safety profile. This study aimed to assess the risk of psychiatric disorders in patients with acne who are taking isotretinoin. METHODS We used de-identified information from Taiwan's National Health Insurance Research Database from 2000 to 2015 to examine the risk for psychiatric disorders among patients with acne who were taking isotretinoin. We performed subgroup analyses based on the dosage and duration of isotretinoin administration. RESULTS This study included 29,943 participants during a 16-year follow-up period. We found no significantly increased risk for psychiatric disorders among patients taking isotretinoin compared with patients who did not receive isotretinoin treatment (adjusted hazard ratio [aHR]: 1.009, 95% confidence interval [CI]: 0.422-1.696). Subgroup analyses showed no significantly increased risk for psychiatric disorders in patients taking different doses of isotretinoin (≤ 20 mg per day, aHR: 0.892, 95% CI: 0.371-1.501; > 20 mg per day, aHR: 1.068, 95% CI: 0.446-1.798). There was also no significant increase in risk for patients undergoing isotretinoin treatment over different periods (≤ 6 months, aHR: 0.924, 95% CI: 0.392-1.612; > 6 months, aHR: 1.196, 95% CI: 0.488-2.004). LIMITATIONS We did not analyze the risk of suicidal ideation, and it could be underestimated in medical claims databases. CONCLUSIONS We found no increased risk of psychiatric disorders among Taiwanese patients with acne who were taking isotretinoin. Higher dosage or longer duration of isotretinoin treatment did not increase the risk for developing a psychiatric disorder.

Abstract
Depression is a common but serious mental disorder and can be caused by the side effects of medications. Evidence from abundant clinical case reports and experimental animal models has revealed the association between the classic anti-acne drug 13-cis-retinoic acid (13-cis-RA) and depressive symptoms. However, direct experimental evidence of this mechanism and information on appropriate therapeutic rescue strategies are lacking. Herein, our data revealed that chronic administration of 13-cis-RA to adolescent mice induced depression-like behavior but not anxiety-like behavior. We next demonstrated that chronic 13-cis-RA application increased neural activity in the dentate gyrus (DG) using c-Fos immunostaining, which may be critically involved in some aspects of depression-like behavior. Therefore, we assessed electrophysiological functions by obtaining whole-cell patch-clamp recordings of dentate granule cells (DGCs), which revealed that chronic 13-cis-RA treatment shifted the excitatory-inhibitory balance toward excitation and increased intrinsic excitability. Furthermore, a pharmacogenetic approach was performed to repeatedly silence DGCs, and this manipulation could rescue depression-like behavior in chronically 13-cis-RA-treated mice, suggesting DGCs as a potential cellular target for the direct alleviation of 13-cis-RA-induced depression.

Abstract
Depression is a serious mental and mood disorder with global health and economic burden. This burden may be overwhelming in low income countries, although there are insufficient data. Most antidepressant formulations are predicated on the monoamine, neuroendocrine and neuro-inflammation hypotheses, with little or no cognizance to other neurochemicals altered in depression. A nutritional strategy with or without conventional antidepressants is recommended, as nutrition plays vital roles in the onset, severity and duration of depression, with poor nutrition contributing to its pathogenesis. This review discusses nutritional potentials of utilizing omega-3 fatty acids, proteins, vitamins, minerals and herbs or their phytochemicals in the management of depression with the aim of reducing depression burden. Literature search of empirical data in books and journals in data bases including but not limited to PubMed, Scopus, Science Direct, Web of Science and Google Scholar that might contain discussions of sampling were sought, their full text obtained, and searched for relevant content to determine eligibility. Omega-3 fatty and amino acids had significant positive anti-depression outcomes, while vitamins and minerals although essential, enhanced omega-3 fatty and amino acids activities. Some herbs either as whole extracts or their phytochemicals/metabolites had significant positive anti-depression efficacy. Nutrition through the application of necessary food classes or herbs as well as their phytochemicals, may go a long way to effectively manage depression. This therefore will provide inexpensive, natural, and non-invasive therapeutic means with reduced adverse effects that can also be applied alongside clinical management. This nutritional strategy should be given more attention in research, assessment and treatment for those with depression and other mental illness in low income countries, especially in Africa.

Abstract
Background Isotretinoin (13-cis-retinoic acid, marketed under the names Accutane, Roaccutane, and others) is an effective treatment for acne that has been on the market for over 30 years, although reports of neuropsychiatric side effects continue to be reported. Isotretinoin is an isomer of the active form of Vitamin A, 13-trans-retinoic acid, which has known psychiatric side effects when given in excessive doses, and is part of the family of compounds called retinoids, which have multiple functions in the central nervous system. Methods The literature was reviewed in pubmed and psychinfo for research related to isotretinoin and neuropsychiatric side effects including depression, suicidal thoughts, suicide, mania, anxiety, impulsivity, emotional lability, violence, aggression, and psychosis. Results Multiple case series have shown that successful treatment of acne with isotretinoin results in improvements in measures of quality of life and self esteem However, studies show individual cases of clinically significant depression and other neuropsychiatric events that, although not common, are persistent in the literature. Since the original cases of depression were reported to the United States Food and Drug Administration, numerous cases have been reported to regulatory agencies in the United Kingdom, France, Ireland, Denmark, Australia, Canada, and other countries, making isotretinoin one of the top five medications in the world associated with depression and other neuropsychiatric side effects. Clinicians are advised to warn patients of the risks of neuropsychiatric side effects with isotretinoin which may arise from the medication itself, and not just as a side effect of acne or youth.

Abstract
Retinoic acid (RA), the principal active metabolite of vitamin A, is known to be involved in stress-related disorders. However, its mechanism of action in this regard remains unclear. This study reports that, in mice, endogenous cellular RA binding protein 1 (Crabp1) is highly expressed in the hypothalamus and pituitary glands. Crabp1 knockout (CKO) mice exhibit reduced anxiety-like behaviors accompanied by a lowered stress induced-corticosterone level. Furthermore, CRH/DEX tests show an increased sensitivity (hypersensitivity) of their feedback inhibition in the hypothalamic-pituitary-adrenal (HPA) axis. Gene expression studies show reduced FKBP5 expression in CKO mice; this would decrease the suppression of glucocorticoid receptor (GR) signaling thereby enhancing their feedback inhibition, consistent with their dampened corticosterone level and anxiety-like behaviors upon stress induction. In AtT20, a pituitary gland adenoma cell line elevating or reducing Crabp1 level correspondingly increases or decreases FKBP5 expression, and its endogenous Crabp1 level is elevated by GR agonist dexamethasone or RA treatment. This study shows, for the first time, that Crabp1 regulates feedback inhibition of the the HPA axis by modulating FKBP5 expression. Furthermore, RA and stress can increase Crabp1 level, which would up-regulate FKBP5 thereby de-sensitizing feedback inhibition of HPA axis (by decreasing GR signaling) and increasing the risk of stress-related disorders.

All-trans retinoic acid induces synaptopodin-dependent metaplasticity in mouse dentate granule cells. eLife 2021; 10:71983. [PMID: 34723795 PMCID: PMC8560091 DOI: 10.7554/elife.71983] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/21/2021] [Accepted: 10/15/2021] [Indexed: 12/27/2022] Open
Abstract
Previously we showed that the vitamin A metabolite all-trans retinoic acid (atRA) induces synaptic plasticity in acute brain slices prepared from the mouse and human neocortex (Lenz et al., 2021). Depending on the brain region studied, distinct effects of atRA on excitatory and inhibitory neurotransmission have been reported. Here, we used intraperitoneal injections of atRA (10 mg/kg) in adult C57BL/6J mice to study the effects of atRA on excitatory and inhibitory neurotransmission in the mouse fascia dentata—a brain region implicated in memory acquisition. No major changes in synaptic transmission were observed in the ventral hippocampus while a significant increase in both spontaneous excitatory postsynaptic current frequencies and synapse numbers were evident in the dorsal hippocampus 6 hr after atRA administration. The intrinsic properties of hippocampal dentate granule cells were not significantly different and hippocampal transcriptome analysis revealed no essential neuronal changes upon atRA treatment. In light of these findings, we tested for the metaplastic effects of atRA, that is, for its ability to modulate synaptic plasticity expression in the absence of major changes in baseline synaptic strength. Indeed, in vivo long-term potentiation (LTP) experiments demonstrated that systemic atRA treatment improves the ability of dentate granule cells to express LTP. The plasticity-promoting effects of atRA were not observed in synaptopodin-deficient mice, therefore, extending our previous results regarding the relevance of synaptopodin in atRA-mediated synaptic strengthening in the mouse prefrontal cortex. Taken together, our data show that atRA mediates synaptopodin-dependent metaplasticity in mouse dentate granule cells.

Abstract
We relay the case of a teenage female with severe facial acne vulgaris and a past psychiatric history of major depressive disorder who presented to the emergency department with a primary complaint of ongoing suicidal ideation. Defining features of this case stem from the patient endorsing that her suicidal ideation was a result of her severe acne and the coinciding social perturbation it caused. Additionally, the patient reported that just four months prior to the current presentation, her dermatologist started her on isotretinoin therapy for the management of acne vulgaris. To the best of the authors' knowledge, there have been no reported cases which describe a teenage female presenting with active suicidal ideation secondary to severe acne vulgaris while concurrently undergoing treatment with isotretinoin. Given the controversial but reported association between isotretinoin and increased suicidality, we considered the appropriateness of continuing this medication for our patient. We then conducted a literature search evaluating the evidence concerning this association. In what follows, we present a unique case report and provide a thorough review of the evidence-or lack thereof-surrounding the relationship between isotretinoin and suicidality. Additionally, the authors aim to provide recommendations for the management of future patients who may present under similar circumstances.

Abstract
Family and population studies indicate clear heritability of major depressive disorder (MDD), though its underlying biology remains unclear. The majority of single-nucleotide polymorphism (SNP) linkage blocks associated with MDD by genome-wide association studies (GWASes) are believed to alter transcriptional regulators (e.g., enhancers, promoters) based on enrichment of marks correlated with these functions. A key to understanding MDD pathophysiology will be elucidation of which SNPs are functional and how such functional variants biologically converge to elicit the disease. Furthermore, retinoids can elicit MDD in patients and promote depressive-like behaviors in rodent models, acting via a regulatory system of retinoid receptor transcription factors (TFs). We therefore sought to simultaneously identify functional genetic variants and assess retinoid pathway regulation of MDD risk loci. Using Massively Parallel Reporter Assays (MPRAs), we functionally screened over 1000 SNPs prioritized from 39 neuropsychiatric trait/disease GWAS loci, selecting SNPs based on overlap with predicted regulatory features-including expression quantitative trait loci (eQTL) and histone marks-from human brains and cell cultures. We identified >100 SNPs with allelic effects on expression in a retinoid-responsive model system. Functional SNPs were enriched for binding sequences of retinoic acid-receptive transcription factors (TFs), with additional allelic differences unmasked by treatment with all-trans retinoic acid (ATRA). Finally, motifs overrepresented across functional SNPs corresponded to TFs highly specific to serotonergic neurons, suggesting an in vivo site of action. Our application of MPRAs to screen MDD-associated SNPs suggests a shared transcriptional-regulatory program across loci, a component of which is unmasked by retinoids.

Abstract
Acne is associated with depression and anxiety; however, the relationship between acne and suicide is still unclear. This study is aimed to evaluate the association between acne and suicide by conducting a meta-analysis. Studies were identified by electronic searches of the PubMed and EMBASE databases from their inception through Jan 10, 2020. Two authors separately assessed the quality and extracted data from the selected studies. When the heterogeneity was significant, we used a random-effects model to calculate overall pooled risk estimates.Five studies involving a total of 2,276,798 participants were finally included in the meta-analysis; 52,075 participants had acne. Suicide was positively associated with acne in the overall analysis (odds ratio (OR) 1.50, 95% confidence interval (95% CI): 1.09-2.06, P = .004, I2 = 74.1%). Subgroup analyses were performed for suicidal behavior groups (P = .002, I2 = 80.4%), suicidal ideation or thoughts groups (P = .849, I2 = 0.0%), International Classification of Diseases version 9 (ICD-9) groups (P = .137, I2 = 49.6%), non-ICD-9 groups (P = .950, I2 = 0.0%), American groups (P = .311, I2 = 2.4%), and non-American groups (P = .943, I2 = 0.0%). Sensitivity analyses indicated flawed results. No publication bias was detected.Acne may significantly increase suicide risk. Clinicians should actively treat acne and consider suicide screening. Further international studies with high-quality analyses are needed as more data are published.Ethical approval and patient consent are not required because this study is a literature-based study.

Abstract
A defining feature of the brain is the ability of its synaptic contacts to adapt structurally and functionally in an experience-dependent manner. In the human cortex, however, direct experimental evidence for coordinated structural and functional synaptic adaptation is currently lacking. Here, we probed synaptic plasticity in human cortical slices using the vitamin A derivative all-trans retinoic acid (atRA), a putative treatment for neuropsychiatric disorders such as Alzheimer's disease. Our experiments demonstrated that the excitatory synapses of superficial (layer 2/3) pyramidal neurons underwent coordinated structural and functional changes in the presence of atRA. These synaptic adaptations were accompanied by ultrastructural remodeling of the calcium-storing spine apparatus organelle and required mRNA translation. It was not observed in synaptopodin-deficient mice, which lack spine apparatus organelles. We conclude that atRA is a potent mediator of synaptic plasticity in the adult human cortex.

Abstract
BACKGROUND The association between isotretinoin and psychiatric disturbance, including depression and suicidal behavior, is controversial. OBJECTIVE To investigate whether acne patients prescribed isotretinoin or antibiotics were more likely to have psychiatric disorders and/or engage in suicidal behavior. METHODS Retrospective cohort study using the IBM MarketScan Research Databases, which contain commercial insurance claims in the United States, to identify acne patients who were prescribed isotretinoin or oral antibiotics between 2011 and 2017 and who were diagnosed with psychiatric disorders or suicidal behavior. RESULTS A total of 72,555 patients were included in the study. Patients in the general population were 1.47 times more likely to be diagnosed with suicidal ideation or attempt compared to acne patients prescribed isotretinoin (adjusted odds ratio [OR] 1.47; confidence interval [95% CI], 1.27, 1.70; P < .0001). The general population (adjusted OR 0.87; 95% CI, 0.84, 0.89; P < .0001) and acne patients prescribed antibiotics (adjusted OR 0.88; 95% CI, 0.85, 0.91; P < .0001) were less likely to have a psychiatric diagnosis compared to acne patients prescribed isotretinoin. The prevalence of suicidal behavior during isotretinoin treatment was lower (0.10%; P = .082) than in the year prior to isotretinoin treatment (0.22%) and in the year following treatment (0.34%; P = .004). LIMITATIONS The study excluded individuals with public insurance and those who were uninsured, and the data in the study relied on the accuracy of the medical coding. CONCLUSIONS Compared to the general population, acne patients prescribed isotretinoin were less likely to engage in suicidal behavior. Further exploration into the slight increase in suicidal behavior seen in isotretinoin patients 1 year after therapy is warranted.

Abstract
AIM Impairment of biotin metabolism with the use of isotretinoin and the mucocutaneous side effects observed in patients using isotretinoin suggests that they are a result of decreased enzyme activity. We aimed to determine the pattern of skin and hair changes in patients with acne receiving isotretinoin and how these changes were affected by biotin added to the treatment. MATERIALS AND METHODS Sixty patients were divided into two groups. Each group contained 30 patients. Groups A and B received 0.5 mg/kg/day isotretinoin, and 10 mg/day biotin supplement was added to Group B. Both groups were evaluated using a digital dermoscope for hair changes and with a DermaLab® Combo device for transepidermal water loss (TEWL), skin retraction, skin hydration, and skin sebum levels at the beginning and end of the fourth month. RESULTS In group B, the anagen hair ratio increased (P = 0.034) and the telogen hair ratio decreased significantly (P = 0.003). Skin sebum and the skin retraction values decreased in both groups. Skin hydration decreased significantly in group A (P = 0.001), but there was no significant decrease in group B (P = 0.43). CONCLUSION Biotin (10 mg/day) given in addition to isotretinoin treatment decreased telogen and increased anagen hair rates and helped to maintain skin hydration. The use of 10 mg/day biotin can prevent the mucocutaneous adverse effects of isotretinoin treatment.

Abstract
Background The association between isotretinoin administration and depression in acne patients remains controversial. We aim to estimate the prevalence of depression among patients with acne vulgaris before and after treatment with isotretinoin in Riyadh, Saudi Arabia. Methods This was a prospective study on patients attending the King Khalid University Hospital (KKUH), a tertiary institution, who were prescribed isotretinoin for the treatment of acne vulgaris for the first time. The Beck Depression Inventory (BDI) was used to screen for depressive symptoms. Results A total of 179 patients were included in the study. The patients were then divided into two groups based on the treatment modality that they received: one group taking isotretinoin and the other treatment group who used other medications, including Retin-A (tretinoin) and Tazorac (tazarotene). A total of 119 patients were in the isotretinoin group with 91.6%, 2.5%, 1.7%, and 3.4% of those patients having a normal mood, mild depression, moderate depression, and severe depression scores before starting isotretinoin treatment, respectively. After three months of treatment, 94.1%, 1.7%, 0.8%, and 2.5% of patients had normal mood, mild depression, moderate depression, and severe depression, respectively. Meanwhile, after six months of treatment, 95.8%, 0.8%, 0%, and 1.7% of patients had normal mood, mild depression, moderate depression, and severe depression, respectively. The mean BDI score at the baseline was 3.31 ± 6.98 for isotretinoin and 3.17 ± 6.27 for other treatments. Compared to the baseline, patients using the isotretinoin showed a significant reduction in depression scores at three months (2.64 ± 6.17; p-value < 0.001), six months (1.99 ± 5.08; p-value < 0.001), and across all follow-up points (p-value < 0.001). Similar results were also estimated for the other treatment group, including Retin-A (tretinoin), adapalene, benzoyl peroxide, and doxycycline; however, no significant difference was noticed between the two groups (p-value = 0.885). Conclusion Isotretinoin treatment for acne does not appear to be associated with a statistically significant increased risk of depression in our population. Therefore, more studies are needed to understand this reflection in Saudi Arabia.

Eur J Neurosci 2021; 55:2955-2970. [PMID: 33502040 DOI: 10.1111/ejn.15127] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/28/2020] [Revised: 01/08/2021] [Accepted: 01/18/2021] [Indexed: 01/02/2023]
Abstract
Studies in human and non-human species suggest that decision-making behaviour can be biased by an affective state, also termed an affective bias. To study these behaviours in non-human species, judgement bias tasks (JBT) have been developed. Animals are trained to associate specific cues (tones) with a positive or negative/less positive outcome. Animals are then presented with intermediate ambiguous cues and affective biases quantified by observing whether animals make more optimistic or more pessimistic choices. Here we use a high versus low reward JBT and test whether pharmacologically distinct compounds, which induce negative biases in learning and memory, have similar effects on decision-making: tetrabenazine (0.0-1.0 mg/kg), retinoic acid (0.0-10.0 mg/kg), and rimonabant (0.0-10.0 mg/kg). We also tested immunomodulatory compounds: interferon-α (0-100 units/kg), lipopolysaccharide (0.0-10.0 μg/kg), and corticosterone (0.0-10.0 mg/kg). We observed no specific effects in the JBT with any acute treatment except corticosterone which induced a negative bias. We have previously observed a similar lack of effect with acute but not chronic psychosocial stress and so next tested decision-making behaviour following chronic interferon-alpha. Animals developed a negative bias which was sustained even after treatment was ended. These data suggest that decision-making behaviour in the task is sensitive to chronic but not acute effects of most pro-depressant drugs or immunomodulators, but the exogenous administration of acute corticosterone induces pessimistic behaviour. This work supports our hypothesis that biases in decision-making develop over a different temporal scale to those seen with learning and memory which may be relevant in the development and perpetuation of mood disorders.

Abstract
A growing number of vaccines are administered at the same time or in close succession, increasing the complexity of assessing vaccine safety. Individual vaccines are assumed to have no other effect than protection against the targeted pathogen, but vaccines also have nonspecific and interactive effects, the outcomes of which can be beneficial or harmful. To date, no controlled trials and very few observational studies have determined the impact of vaccination schedules on overall health. The balance of the risks and benefits from mass vaccination therefore remains uncertain. Recent studies worryingly suggest links between multiple vaccinations and increased risks of diverse multisystem health problems, including allergies, infections, and neuropsychiatric or neurodevelopmental disorders. Here, we propose that, in susceptible persons, multiple vaccinations activate the retinoid cascade and trigger apoptotic hepatitis, leading to cholestatic liver dysfunction, in which stored vitamin A compounds (retinyl esters and retinoic acid) enter the circulation in toxic concentrations; this induces endogenous forms of hypervitaminosis A, with the severity of adverse outcomes being directly proportional to the concentration of circulating retinoids. In very low concentrations, vitamin A and its major metabolite retinoic acid contribute to immune function and to the process of immunization, whereas excess vitamin A increases the risk of adverse events, including common "side-effects" as well as chronic adverse outcomes. The increasing rates of allergy, ear infections, and neurodevelopmental disorders (NDDs) in countries with high rates of vaccination could be related to mass vaccination and to its impact on liver function and vitamin A metabolism, collectively representing endogenous manifestations of hypervitaminosis A. Further studies of health outcomes in vaccinated and unvaccinated groups are urgently needed, to increase understanding of the pathophysiology and treatment of vaccine injury, to identify the risk factors and screen for vaccine injury, to inform public health policy on potential hazards related to vaccination schedules, and to optimize the safety and benefits of vaccines.

Abstract
Affecting approximately 9.4% of the population worldwide, acne vulgaris is a common chronic inflammatory skin disease. Medical students are exposed to higher levels of stress and have a higher prevalence of acne. However, the risk factors and the impact of acne on medical students' mental health remains poorly understood. The aim of this literature review is to: (i) summarize the prevalence and risk factors of acne vulgaris in medical students and (ii) highlight the impact of psychological consequences of acne in medical students. A literature search was conducted using MEDLINE and EMBASE in OVID, using variations in the following search terms: acne vulgaris, medical students, self-esteem, psychology, psychiatry, suicide, suicidal thoughts, self-harm, positive and negative effects, psychological well-being, anxiety, and depression. Studies that stated the prevalence or risk factors of acne vulgaris and/or examined the association between psychosocial effects and acne vulgaris in medical students were included. Eleven cross-sectional studies were included. The prevalence of acne vulgaris in medical students ranged from 34.38% to 97.9% across nine studies. Review of these articles revealed that acne prevalence is associated with stress, gender differences, and lifestyle factors in medical students. Acne had many negative psychological and social impacts on medical students including negative self-image, lower confidence, embarrassment, depression, anxiety, social withdrawal, and impaired social behaviors. Further research on the intersection between acne vulgaris and the mental health of medical students is needed.

Abstract
BACKGROUND More and more people are suffering from depression in modern society. It is believed that the development of depression results from alterations in synaptic transmission, especially in the hippocampus. Animal experiments and clinical studies have demonstrated that retinoids are essential components in hippocampal synaptic plasticity, and they have a close relationship with depression. However, it is still unclear how excessive retinoic acid (RA) causes depression and what synaptic and molecular mechanisms underlie it. METHODS Behavioral, electrophysiological, and molecular approaches were employed to characterize the effects of RA on depression and synaptic plasticity. RA was continuously administered intracerebroventricularly through an osmotic pump. RESULTS RA treatment induced depression-like behaviors, as evidenced by decreased sucrose preference and increased immobile duration in both the forced swim test and the tail suspension test. RA administration also induced anxiety-like behaviors, indicated by decreased duration in the open arms of the elevated plus maze and the central of the open field. RA treatment decreased the neuronal excitability of the hippocampus either by changing the excitatory/inhibitory receptor balance or by promoting the synthesis of inhibitory neurotransmitters. Moreover, long-term potentiation was decreased in both the excitatory postsynaptic potential and the population spike in RA-treated rats, presumably a consequence of the reduced glur1 transcript level. LIMITATIONS The mechanism of how excess RA affects the hippocampal gene expression and synaptic plasticity requires further study. CONCLUSIONS RA treatment can induce depression-like behavior in rats and impair hippocampal plasticity. Thus, improving synaptic plasticity in the hippocampus may ameliorate the affective disorders caused by excessive RA.

Abstract
Isotretinoin, an active form of vitamin A, is the drug of last resort for the treatment of severe acne. Depression, suicidal ideation, and psychosis are among the most well-documented psychiatric side effects. Here, we report a case of isotretinoin-induced psychosis, which was diagnosed as delusional disorder somatic subtype, in a young male in the absence of any prodromal symptoms, previous psychiatric history, or family history of mental illness. The onset of psychosis was in the context of a dosage increase from 40 mg/day to 80 mg/day. Isotretinoin was discontinued, and the patient showed improvement on low-dose quetiapine.

Abstract
INTRODUCTION Acne is a chronic, inflammatory, and immune mediated disease of pilosebaceous unit, highly prevalent in adolescents. It involves face, trunk, and back; may leave scars and affect quality of life. Early, effective, and safe treatment is the key for disease resolution. Oral isotretinoin is the unique treatment for cure or prolonged remission for moderate and severe acne, preventing psychosocial impact and scars. It inhibits sebaceous glands activity and has anti-inflammatory and immunoregulatory properties. AREAS COVERED We performed a comprehensive literature search on PubMed database, up to March 2020, regarding oral isotretinoin for acne treatment. We synthetized data about acne pathogenesis and mechanism of action, efficacy, and safety of isotretinoin. EXPERT OPINION This drug is effective, despite common, controllable, and reversible mucocutaneous side effects. Serious adverse events are rare and represent individual reactions. Teratogenicity is the most severe, requiring rigorous control. We believe that no other therapeutic option, even topicals combined to oral antibiotics accomplish same results. Recurrence after treatments other than isotretinoin is the rule, prolonging risk of scars, compromising skin appearance, and causing emotional distress in teenagers. If there is no absolute contraindication, isotretinoin should be the first line treatment for moderate to severe inflammatory acne.

Abstract
Isotretinoin, a synthetic vitamin A derivative, is primarily used in the
management of severe nodulocystic acne. Since its introduction, isotretinoin has
been linked with various psychiatric side effects. In particular, depression and
suicidality have been extensively reported as side effects. This case report
features a young male who developed a first psychotic episode within 3 months of
starting isotretinoin therapy. The patient was hospitalized, and organic
pathologies and use of psychoactive substances that could explain his
presentation were ruled out. After stopping isotretinoin and starting olanzapine
10 mg, the psychotic symptoms remitted completely within 2 weeks. This case
highlights the need for increased vigilance toward psychiatric manifestations of
isotretinoin. In addition, it suggests that secondary psychosis should be
considered as a differential diagnosis by clinicians, especially in patients
with no past psychiatric history or family history of mental illness.
