Abstract
Objective Biotin has widespread popularity as a hair supplement. We sought to review the literature regarding biotin's efficacy as a hair supplement. Methods We conducted a literature search of PubMed for articles specifically studying the use of oral biotin for hair growth or quality. Case reports and case series were excluded. Results Three studies met our inclusion criteria. The first study was the highest quality, with a double-blind and placebo-controlled study design, but their results found no difference between the biotin and placebo groups for hair growth. The other two studies investigated specific patient populations (patients on isotretinoin and female patients post-sleeve gastrectomy). Both studies were susceptible to multiple potential biases and neither had striking results in favor of biotin. Limitations Our review is limited by lack of available studies. Conclusion Given the widespread popularity of biotin as a hair supplement, one would presume that this claim must be grounded in strong evidence; however, there is a large discrepancy between the public's perception of its efficacy and the scientific literature. The utility of biotin as a hair supplement is not supported by high-quality studies.

Abstract
Hair dermal papilla cells (hDPCs) play a crucial role in hair growth and regeneration, and their function is influenced by nutrient and oxygen supply. A microenvironment with significantly low oxygen (O2) levels, known as anoxic conditions (<0.2%) due to oxygen deficiency, hinders hDPC promotion and retards hair regrowth. Here, a nanoemulsion (NE) based on perfluorooctyl bromide (PFOB), a member of the perfluorocarbon family, is presented to provide a sustainable O2 supply and maintain physical stability in vitro. The PFOB-NE has been shown to continuously release oxygen for 36 h, increasing and maintaining the O2 concentration in the anoxic microenvironment of up to 0.8%. This sustainable O2 supply using PFOB-NE has promoted hDPC growth and also induced a complex cascade of effects. These effects encompass regulation via inhibiting lactate accumulation caused via oxygen deficiency, increasing lactate dehydrogenase activity, and promoting the expression of genes, such as the hypoxia-inducible factor 1 family and NADPH oxidase 4 under anoxic conditions. Sustained O2 supply is shown to enhance human hair organ elongation approximately four times compared to the control under anoxic conditions. In conclusion, the perfluorocarbon-based NE containing oxygen proves to be an important strategic tool for improving hair growth and alleviating hair loss.

Abstract
Background Many patients with polycystic ovary syndrome (PCOS) exhibit female pattern hair loss (FPHL). A more advanced, efficient, and suitable therapeutic approach is required to effectively manage FPHL in patients with PCOS. Aim Dr. SKS Hair Booster Serum is composed of copper, niacinamide, hyaluronic acid, thiamine, riboflavin, and biotin; each of these constituents has demonstrated individual efficacy in promoting hair growth and enhancing hair quality. We hereby assess the effectiveness of this novel hair formulation in treating FPHL in PCOS. Methods This was an open-label, non-randomized, multicenter, prospective, large study with a wide range of age groups. The study involving 1,000 females aged 25-50 years, diagnosed with PCOS and having complaints of FPHL with Ludwig grades I and II. Each patient received a monthly session of Dr. SKS Hair Booster Serum, with 1 mL of serum administered through injection into the superficial layer (dermis) of the scalp using a tiny infusion via an insulin syringe, mesotherapy, or via a derma roller/derma pen. All the patients were subjected to standard global photography, video microscopic assessment (vellus hair counts, terminal hair counts, and hair shaft diameter), and a subject self-assessment questionnaire at baseline and six months after the treatment. Results After six months of the treatment, the hair shaft diameter, terminal hair counts, and hair growth rate were significantly increased than baseline (p≤0.0001), and a significant reduction was noted in vellus hair counts than baseline measurement (p<0.00001). These findings are suggestive of improved hair regrowth after the treatment. No adverse events were recorded during the study. Statistically significant improvements were observed in hair parameters (overall hair fall rate, hair texture, hair volume, and scalp itching) after six months of treatment than baseline. Conclusion Dr. SKS Hair Booster Serum has been shown to be an effective treatment for FPHL in patients with PCOS. This study marks the first investigation into the use of Dr. SKS Hair Booster Serum in patients with PCOS.

Abstract
Objective Biotin is widely known to be beneficial for the hair, nails, and skin, but there are only a few studies on biotin. We evaluated whether there is a relationship between biotin levels and age, gender, and frequently observed laboratory findings. We also evaluated biotin levels according to the reason for checking biotin levels. Methods One hundred five patients applied to the dermatology outpatient clinic and had their biotin levels checked. Patient files were retrospectively analyzed. Results There were a weak positive (r=0.207) relationship between biotin levels and basophil count, a weak positive (r=0.201) relationship between biotin levels and creatinine, and a weak positive (r=0.314) relationship between biotin levels and cholesterol/triglyceride ratio. There were a weak negative (r=-0.216) relationship between biotin levels and mean platelet volume (MPV) and a moderately negative (r=-0.315) relationship between biotin levels and triglyceride levels. Conclusion Biotin levels do not significantly differ with gender but increase with age. Although a weak correlation was detected between hemogram parameters and biotin levels with basophil percentage and mean platelet volume values, biotin did not significantly change hemogram parameters. The relationship between biotin levels and triglyceride levels was the most critical finding of our study. We recommend examining biotin levels in the patients with high triglyceride levels. When we encounter dermatological side effects related to the use of epidermal growth factor receptor tyrosine kinase inhibitors, we recommend evaluating biotin levels. We recommend that biotin supplementation be made only in the patients with deficiencies and that biotin levels be measured in the follow-up.

Abstract
The influence of environmental factors on the development of autoimmune disease is being broadly investigated to better understand the multifactorial nature of autoimmune pathogenesis and to identify potential areas of intervention. Areas of particular interest include the influence of lifestyle, nutrition, and vitamin deficiencies on autoimmunity and chronic inflammation. In this review, we discuss how particular lifestyles and dietary patterns may contribute to or modulate autoimmunity. We explored this concept through a spectrum of several autoimmune diseases including Multiple Sclerosis (MS), Systemic Lupus Erythematosus (SLE) and Alopecia Areata (AA) affecting the central nervous system, whole body, and the hair follicles, respectively. A clear commonality between the autoimmune conditions of interest here is low Vitamin D, a well-researched hormone in the context of autoimmunity with pleiotropic immunomodulatory and anti-inflammatory effects. While low levels are often correlated with disease activity and progression in MS and AA, the relationship is less clear in SLE. Despite strong associations with autoimmunity, we lack conclusive evidence which elucidates its role in contributing to pathogenesis or simply as a result of chronic inflammation. In a similar vein, other vitamins impacting the development and course of these diseases are explored in this review, and overall diet and lifestyle. Recent work exploring the effects of dietary interventions on MS showed that a balanced diet was linked to improvement in clinical parameters, comorbid conditions, and overall quality of life for patients. In patients with MS, SLE and AA, certain diets and supplements are linked to lower incidence and improved symptoms. Conversely, obesity during adolescence was linked with higher incidence of MS while in SLE it was associated with organ damage. Autoimmunity is thought to emerge from the complex interplay between environmental factors and genetic background. Although the scope of this review focuses on environmental factors, it is imperative to elaborate the interaction between genetic susceptibility and environment due to the multifactorial origin of these disease. Here, we offer a comprehensive review about the influence of recent environmental and lifestyle factors on these autoimmune diseases and potential translation into therapeutic interventions.

Abstract
Background and aim Androgenetic alopecia (AGA) is a well-known hair loss disorder in both men and women affecting approximately 80% and 50% of the population, respectively. Various treatment options for AGA are available with varying efficacy. Combination therapy is a new dictum to combat AGA. Hence, this study aimed to compare the efficacy of commonly used topical therapies such as Procapil with platelet-rich plasma (PRP) and redensyl, saw palmetto (SP), and biotin (RSB) with PRP. Materials and methods This was a randomized controlled trial conducted on 54 male patients with AGA attending the outpatient department in a tertiary care hospital. Participants were randomly assigned into two equal groups (A and B). Group A participants were treated with Procapil with PRP, and group B participants were treated with redensyl, saw palmetto, and biotin with PRP at three weeks intervals for a total period of four sessions. Clinical improvement was assessed by serial hair photography by a third blinded observer and was recorded. Results A total of 54 individuals were included and were distributed into 27 each in group A and group B. AGA grading score was found significant between the groups with P < 0.05. Conclusion PRP with adjuvants redensyl, saw palmetto, and biotin can be a better alternative to the current therapies of PRP.

Abstract
Background Androgenetic alopecia (AGA) is frequently encountered in dermatological practice; however, there is a lack of approved treatment. At present, only three therapies have been approved for on-label use in androgenetic alopecia: minoxidil, finasteride, and lower-level laser therapy. Micronutrients are primary elements in the normal hair follicle cycle, and their role in androgenetic alopecia is a growing matter of research nowadays. This study aims to investigate the clinical efficacy and safety of Dr. SKS Hair Booster Serum, a cocktail of micronutrients and multivitamins (copper, niacinamide, hyaluronic acid, thiamine, riboflavin, and biotin), in male and female patients with androgenetic alopecia. Methods We did an open-label, non-randomized, multicenter, prospective study across five hair clinic chains in India (Mumbai, Hyderabad, Jabalpur, Balaghat, and Nagpur). Eligible participants were patients with a confirmed diagnosis of androgenetic alopecia based on clinical examination and trichoscopic findings, age of 18 years or older, and any gender. Each patient received Dr. SKS Hair Booster Serum, 1 ml in volume, once a month by mesotherapy or derma roller/derma pen for up to six months. All patients were subjected to a 60-second hair count test (comb test), hair pull test, global photographic assessment (GPA), trichoscopy assessment, patient self-assessment questionnaire, and safety assessment at baseline and six months after the treatment. Results One thousand patients (500 males and females each) with androgenetic alopecia were analyzed. There was a significant reduction in hair fall with bulb (<0.0001) and without bulb (<0.0001) six months after the treatment versus baseline. There was a significant improvement in the number of hairs removed per pull (<0.0001), global photographic assessment score (<0.0001), hair growth rate (<0.0001), follicular hair density (<0.0001), vellus hair density (<0.0001), and terminal hair density (<0.0001) six months after the treatment versus baseline. The majority of patients (95%) were satisfied with six-month treatment of Dr. SKS Hair Booster Serum. No major adverse events were reported during the study. Conclusion Dr. SKS Hair Booster Serum was found to be a safe and effective treatment for androgenetic alopecia, with 95% patient self-assessment score.

Abstract
BACKGROUND Our bodies are a collection of nutrients. For healthy body production and activities, good nutrients must be balanced and supplied steadily. However, as modern people eat more irregular meals and fast food, they are running out of nutrients needed by the human body. As a result, research was conducted on the effect of eggs with good cost-effectiveness on the human body and hair. PURPOSE The purpose of this paper is to review the literature investigated to convey knowledge of the positive nutrients of modern people's nutrition and eggs. METHODS These data were reviewed to identify agreement between each section and the unique guiding area. Regarding the survey criteria, it was finally decided that 31 papers were suitable for evaluating the purpose of research as follows. PRISMA flowcharts allow you to determine the number of records identified, included, and excluded. RESULTS Eggs are considered the most cost-effective foods that deliver protein, biotin, choline, and vitamin A to the world, and eggs that can be easily consumed are known as nutritional foods because they contain protein, lipids, minerals, and embryonic development growth factors. It is widely consumed as a food that can be eaten by anyone, including the elderly and children. CONCLUSIONS In this study, eggs can be used as important data for modern people by delivering nutrients to the human body and hair of modern people and understanding positive nutrients.

Abstract
The hair cycle is composed of four primary phases: anagen, catagen, telogen, and exogen. Anagen is a highly mitotic phase characterized by the production of a hair shaft from the hair follicle, whereas catagen and telogen describe regression and the resting phase of the follicle, respectively, ultimately resulting in hair shedding. While 9% of hair follicles reside in telogen at any time, a variety of factors promote anagen to telogen transition, including inflammation, hormones, stress, nutritional deficiency, poor sleep quality, and cellular division inhibiting medication. Conversely, increased blood flow, direct stimulation of the hair follicle, and growth factors promote telogen to anagen transition and subsequent hair growth. This review seeks to comprehensively describe the hair cycle, anagen and telogen balance, factors that promote anagen to telogen transition and vice versa, and the clinical utility of a variety of lab testing and evaluations. Ultimately, a variety of factors impact the hair cycle, necessitating a holistic approach to hair loss.

Abstract
OBJECTIVES Gut microbiota is a key component in obesity and type 2 diabetes, yet mechanisms and metabolites central to this interaction remain unclear. We examined the human gut microbiome's functional composition in healthy metabolic state and the most severe states of obesity and type 2 diabetes within the MetaCardis cohort. We focused on the role of B vitamins and B7/B8 biotin for regulation of host metabolic state, as these vitamins influence both microbial function and host metabolism and inflammation. DESIGN We performed metagenomic analyses in 1545 subjects from the MetaCardis cohorts and different murine experiments, including germ-free and antibiotic treated animals, faecal microbiota transfer, bariatric surgery and supplementation with biotin and prebiotics in mice. RESULTS Severe obesity is associated with an absolute deficiency in bacterial biotin producers and transporters, whose abundances correlate with host metabolic and inflammatory phenotypes. We found suboptimal circulating biotin levels in severe obesity and altered expression of biotin-associated genes in human adipose tissue. In mice, the absence or depletion of gut microbiota by antibiotics confirmed the microbial contribution to host biotin levels. Bariatric surgery, which improves metabolism and inflammation, associates with increased bacterial biotin producers and improved host systemic biotin in humans and mice. Finally, supplementing high-fat diet-fed mice with fructo-oligosaccharides and biotin improves not only the microbiome diversity, but also the potential of bacterial production of biotin and B vitamins, while limiting weight gain and glycaemic deterioration. CONCLUSION Strategies combining biotin and prebiotic supplementation could help prevent the deterioration of metabolic states in severe obesity. TRIAL REGISTRATION NUMBER NCT02059538.

Abstract
Hair loss is a widespread concern in dermatology clinics, affecting both men's and women's quality of life. Hair loss can have many different causes, which are critical to identify in order to provide appropriate treatment. Hair loss can happen due to many variables, such as genetic factors or predisposition, vitamin and mineral deficiencies, skin problems, hair growth disorders, poor diet, hormonal problems, certain internal diseases, drug use, stress and depression, cosmetic factors, childbirth, and the chemotherapy process. Treatment for hair loss varies depending on the type of alopecia, deficiency, or excess of structures such as vitamins and minerals, and also on hair and skin structure. The Mediterranean diet is characterized by low amounts of saturated fat, animal protein, and high amounts of unsaturated fat, fiber, polyphenols, and antioxidants. The main nutrients found in the Mediterranean Diet are rich in antioxidant, anti-inflammatory components. It also has an important place in hair loss treatment, since recently treatment strategies have included polyphenols and unsaturated oils more and more frequently. The goal of this work was to review published articles examining alopecia and its types, the many micronutrients that affect alopecia, and the role of the Mediterranean diet in alopecia. The literature shows that little is known about hair loss, nutritional factors, and diet, and that the data collected are conflicting. Given these differences, research into the function of diet and nutrition in the treatment of baldness is a dynamic and growing topic.

Intermediate Hair Follicles from Patients with Female Pattern Hair Loss Are Associated with Nutrient Insufficiency and a Quiescent Metabolic Phenotype. Nutrients 2022; 14:nu14163357. [PMID: 36014862 PMCID: PMC9416027 DOI: 10.3390/nu14163357] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/22/2022] [Revised: 08/10/2022] [Accepted: 08/11/2022] [Indexed: 11/28/2022] Open
Abstract
Female pattern hair loss (FPHL) is a non-scarring alopecia resulting from the progressive conversion of the terminal (t) scalp hair follicles (HFs) into intermediate/miniaturized (i/m) HFs. Although data supporting nutrient deficiency in FPHL HFs are lacking, therapeutic strategies are often associated with nutritional supplementation. Here, we show by metabolic analysis that selected nutrients important for hair growth such as essential amino acids and vitamins are indeed decreased in affected iHFs compared to tHFs in FPHL scalp skin, confirming nutrient insufficiency. iHFs also displayed a more quiescent metabolic phenotype, as indicated by altered metabolite abundance in freshly collected HFs and release/consumption during organ culture of products/substrates of TCA cycle, aerobic glycolysis, and glutaminolysis. Yet, as assessed by exogenous nutrient supplementation ex vivo, nutrient uptake mechanisms are not impaired in affected FPHL iHFs. Moreover, blood vessel density is not diminished in iHFs versus tHFs, despite differences in tHFs from different FPHL scalp locations or versus healthy scalp or changes in the expression of angiogenesis-associated growth factors. Thus, our data reveal that affected iHFs in FPHL display a relative nutrient insufficiency and dormant metabolism, but are still capable of absorbing nutrients, supporting the potential of nutritional supplementation as an adjunct therapy for FPHL.

Abstract
This paper aims to quantify the micronutrients in black walnut and address its human health benefits. The metabolic profiling of 11 black walnut cultivars was accomplished using ultra-high-performance liquid chromatography coupled with quadrupole time-of-flight high-resolution mass spectrometer. Results revealed that the highest concentration of vitamin B9 was present in cultivar “Daniel” (avg. relative signal intensity 229.53 × 104 mAU). “Surprise” and “Daniel” cultivars had the highest amount of vitamin B5. However, vitamin A, D3, E, and K showed no significant difference among the cultivars. The vitamin content levels among the cultivars were compared by applying one way ANOVA method with (P < 0.05) significance level. Mineral analysis for the black walnut kernel, Persian walnut, and black walnut protein powder was done using Inductively Coupled Plasma Optical Emission spectroscopy. The experimental data for black walnut kernel is 0.04 mg/g for Fe and 0.03 mg/g for Zn, and for black walnut, protein powder is 0.07 mg/g for Fe and 0.07 mg/g for Zn. The amino acid analysis and comparison with black walnut kernel show that black walnut flour and protein powder have a higher amount of essential and non-essential amino acids. Therefore, researchers, food process engineers, and food product developers should consider the health benefits of black walnuts and explore the commercial potential of this native agroforestry crop.

Abstract
The influence of nutrition on the pathophysiology and clinical severity of inflammatory facial dermatoses such as acne, rosacea, seborrheic dermatitis, and perioral dermatitis has been controversially discussed for years. As part of a modern treatment approach, clinicians should provide patients with information on how their choice of diet might impact their dermatologic diagnosis and could potentially enhance therapeutic outcome. Recently, the concept of a gut-skin axis has gained momentum in the understanding of inflammatory dermatoses, with nutrition considered a contributing factor in this context. For example, gastrointestinal symptoms in rosacea patients may indicate a dysbiosis of the gut microbiome, treatment of which may also improve severity of the skin disease. New research efforts were recently made for acne patients addressing the clinical effects of omega-3 fatty acids and probiotics. In contrast, due to the limited data available, no comparable specific dietary recommendations can yet be made for seborrheic or perioral dermatitis. However, there are promising signs that clinical nutrition and dermatology will be more extensively interlinked in the future, both clinically and scientifically.

Abstract
OBJECTIVE To review the literature on valproate-associated hair abnormalities and the available treatment options. METHODS We searched PubMed and Google Scholar with keywords including "valproate", "valproic acid", "hair", "alopecia", and "effluvium," supplemented with hand search from cross-references. We included all types of studies including case reports in this review. RESULTS The pathophysiology of hair loss includes telogen effluvium, biotin, mineral deficiency, and possibly hyperandrogenism. Diagnosis is based on history of hair loss or abnormalities following valproate treatment, and is confirmed by use of simple clinical tests such as pull test and modified wash test. Treatment involves reassurance and advice on hair care, and if possible drug discontinuation or dose reduction. Medications such as biotin and other vitamins with minerals supplementation is effective for most individuals with hair loss. Other treatment options are agomelatine, topical valproate or minoxidil, though these lack evidence. CONCLUSION Hair abnormalities with valproate are common, benign adverse effects, and management includes general measures and specific treatment options.

Abstract
Vitamins are an indispensable food source and important owing to the enzyme cofactor and catalytic roles they play in the body. Fat-soluble vitamins A, D, E, K, and B12, are stored in the body and can cause problems with their excessive accumulation. Other vitamins rarely accumulate in the body because they dissolve in water and are excreted through the kidneys. Alcoholism, strict diets, insufficient parental nutrition, and gastrointestinal absorption problems may be included in the causes of vitamin deficiencies. Although clinical findings of vitamin deficiencies display different characteristics depending on the vitamins, the signs that generally occur are cutaneous pigmentation, pigmentation on mucous membranes, palmoplantar keratoderma characterized by fissures, palmar streaking, yellow streaking on the nails, nail layering, and intranail hemorrhage.

Abstract
Healthy hair results from a combination of good generalized health and mindful health care practices. Many nutritional deficiencies lead to poor hair health and include changes to hair structure, texture, and viability. Although the mechanisms by which individual nutrients contribute to hair growth and maintenance have yet to be fully resolved, there are a variety of risk factors that predispose an individual to a nutritional deficiency; age, malnutrition, malabsorption, and medication use are among the most common. A thorough history should be taken in a patient with a hair disturbance to identify risk factors for a nutritional deficiency, which will then guide directed laboratory testing and treatment.

Abstract
Androgenetic alopecia (AGA) is the most common variant of male pattern baldness in which occurrence and development of multiple genetic, hormonal, and metabolic factors are involved. We aimed to estimate plasma element content (Mg, Ca, Zn, Cu, Se, Fe), vitamin status (B12, D, E, and folic acid) in patients with AGA using direct colorimetric tests or atomic absorption spectrometry, and the influence of these parameters in the formation of various hair loss patterns. The study included 50 patients with I-IV stages of AGA divided into two groups with normal and high levels of dihydrotestosterone compared with 25 healthy individuals. The presence of two patterns of pathological hair loss in the androgen-dependent (parietal) and androgen-independent (occipital) areas of the scalp was confirmed. It was shown that all patients with AGA have a deficiency of elements (Zn, Cu, Mg, Se) and vitamins (B12, E, D, folic acid). However, the hair loss rate was not due to their content. А positive interrelation between quantitative trichogram parameters in the occipital region and iron metabolism in pairs "hair density vs Fe" and "hair diameter vs ferritin" was shown. In turn, in the parietal region, an inverse correlation of hair diameter with plasma Cu level was found, the most pronouncing in patients with high levels of dihydrotestosterone. The obtained results indicate the importance of multiple micronutrient deficiencies in the AGA occurrence accompanied by the existence of two different hair loss patterns, differently related to the content of certain trace elements and androgens in the blood.

Abstract
The purpose of this study was to observe the effects of a novel combination of inositol-stabilized arginine silicate complex (ASI) and magnesium biotinate (MgB) on the prevention of skin damage after UVB exposure in rats. Forty-nine Sprague-Dawley rats were randomized into one of the following groups: (1) NC, normal control, (2) SC, shaved control, (3) UVB (exposed to UVB radiation), (4) ASI+MgB-L (Low Dose), (5) ASI+MgB-H (High Dose), (6) ASI+MgB-L+MgB cream, (7) ASI+MgB-H+MgB cream. The results showed that ASI+MgB treatment alleviated the macroscopic and histopathological damages in the skin of rats caused by UVB exposure. Skin elasticity evaluation showed a similar trend. ASI+MgB increased serum Mg, Fe, Zn, Cu, Si, biotin, and arginine concentrations and skin hydroxyproline and biotinidase levels while decreasing skin elastase activity (p < 0.05) and malondialdehyde (MDA) concentration (p < 0.001). Moreover, ASI+MgB treatment increased skin levels of biotin-dependent carboxylases (ACC1, ACC2, PC, PCC, MCC) and decreased mammalian target of rapamycin (mTOR) pathways and matrix metalloproteinase protein levels by the regulation of the activator protein 1 (AP-1), and mitogen activated protein kinases (MAPKs) signaling pathways. In addition, ASI+MgB caused lower levels of inflammatory factors, including TNF-α, NFκB, IL-6, IL-8, and COX-2 in the skin samples (p < 0.05). The levels of Bax and caspase-3 were increased, while anti-apoptotic protein Bcl-2 was decreased by UVB exposure, which was reversed by ASI+MgB treatment. These results show that treatment with ASI and MgB protects against skin damage by improving skin appearance, elasticity, inflammation, apoptosis, and overall health.

Prog Neuropsychopharmacol Biol Psychiatry 2021; 107:110240. [PMID: 33428888 DOI: 10.1016/j.pnpbp.2020.110240] [Citation(s) in RCA: 41] [Impact Index Per Article: 13.7] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/12/2020] [Revised: 11/19/2020] [Accepted: 12/30/2020] [Indexed: 02/06/2023]
Abstract
Despite the well-established roles of B-vitamins and their deficiencies in health and disease, there is growing evidence indicating a key role of those nutrients in functions of the central nervous system and in psychopathology. Clinical data indicate the substantial role of B-vitamins in various psychiatric disorders, including major depression, bipolar disorder, schizophrenia, autism, and dementia, including Alzheimer's and Parkinson's diseases. As enzymatic cofactors, B-vitamins are involved in many physiological processes such as the metabolism of glucose, fatty acids and amino acids, metabolism of tryptophan in the kynurenine pathway, homocysteine metabolism, synthesis and metabolism of various neurotransmitters and neurohormones including serotonin, dopamine, adrenaline, acetylcholine, GABA, glutamate, D-serine, glycine, histamine and melatonin. Those vitamins are highly involved in brain energetic metabolism and respiration at the cellular level. They have a broad range of anti-inflammatory, immunomodulatory, antioxidant and neuroprotective properties. Furthermore, some of those vitamins are involved in the regulation of permeability of the intestinal and blood-brain barriers. Despite the fact that a substantial amount of the above vitamins is acquired from various dietary sources, deficiencies are not uncommon, and it is estimated that micronutrient deficiencies affect about two billion people worldwide. The majority of gut-resident microbes and the broad range of bacteria available in fermented food, express genetic machinery enabling the synthesis and metabolism of B-vitamins and, consequently, intestinal microbiota and fermented food rich in probiotic bacteria are essential sources of B-vitamins for humans. All in all, there is growing evidence that intestinal bacteria-derived vitamins play a significant role in physiology and that dysregulation of the "microbiota-vitamins frontier" is related to various disorders. In this review, we will discuss the role of vitamins in mental health and explore the perspectives and potential of how gut microbiota-derived vitamins could contribute to mental health and psychiatric treatment.

Urinary 3-hydroxyisovaleryl carnitine excretion, protein energy malnutrition and risk of all-cause mortality in kidney transplant recipients: Results from the TransplantLines cohort studies. Clin Nutr 2020; 40:2109-2120. [PMID: 33071013 DOI: 10.1016/j.clnu.2020.09.035] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/14/2020] [Revised: 08/17/2020] [Accepted: 09/28/2020] [Indexed: 10/23/2022]
Abstract
BACKGROUND Leucine is an essential amino acid and a potent stimulator of muscle protein synthesis. Since muscle wasting is a major risk factor for mortality in kidney transplant recipients (KTR), dietary leucine intake might be linked to long-term mortality. Urinary 3-hydroxyisovaleryl carnitine (3-HIC) excretion, a functional marker of marginal biotin deficiency, may also serve as a marker for dietary leucine intake. OBJECTIVE In this study we aimed to investigate the cross-sectional determinants of urinary 3-HIC excretion and to prospectively investigate the association of urinary 3-HIC excretion with all-cause mortality in KTR. DESIGN Urinary 3-HIC excretion and plasma biotin were measured in a longitudinal cohort of 694 stable KTR. Cross-sectional and prospective analyses were performed using ordinary least squares linear regression analyses and Cox regression analyses, respectively. RESULTS In KTR (57% male, 53 ± 13 years, estimated glomerular filtration rate 45 ± 19 mL/min/1.73 m2), urinary 3-HIC excretion (0.80 [0.57-1.16] μmol/24 h) was significantly associated with plasma biotin (std. β = -0.17; P < 0.001). Subsequent adjustment for potential covariates revealed urinary creatinine excretion (std. β = 0.24; P < 0.001) and urinary urea excretion (std. β = 0.53; P < 0.001) as the primary determinant of urinary 3-HIC excretion. Whereas plasma biotin explained only 1% of the variance in urinary 3-HIC excretion, urinary urea excretion explained >45%. During median follow-up for 5.4 [4.8-6.1] years, 150 (22%) patients died. Log2-transformed urinary 3-HIC excretion was inversely associated with all-cause mortality (HR: 0.52 [0.43-0.63]; P < 0.001). This association was independent of potential confounders. CONCLUSIONS Urinary 3-HIC excretion more strongly serves as a marker of leucine intake than of biotin status. A higher urinary 3-HIC excretion is associated with a lower risk of all-cause mortality. Future studies are warranted to explore the underlying mechanism. TRIAL REGISTRATION ID NCT02811835. TRIAL REGISTRATION URL: https://clinicaltrials.gov/ct2/show/NCT02811835.

Abstract
Introduction Scalp inflammation is commonly associated with scalp psoriasis or seborrheic dermatitis. It can aggravate the progression of androgenetic alopecia and cause troublesome itching and burning. Here, we evaluate the efficacy of a shampoo containing 0.075% broad-spectrum cannabidiol in 50 subjects with mild to moderate scalp psoriasis or seborrheic dermatitis. Methods Inflammation was assessed by evaluating the density of twisted/glomerular or arborizing vessels by trichoscopy using a 6-point scale at baseline and day 14. Symptoms of itching/burning sensation, clinical evaluation of erythema/scaling, overall tolerability, and subject satisfaction were evaluated using 10-point scales. Results There were significant reductions in arborizing vessel/twisted capillary inflammation and scaling by day 14. Severity scores reduced from 2.3 ± 0.1, 2.6 ± 0.1, and 3.6 ± 0.1, respectively, to 0.5 ± 0.05, 0.8 ± 0.05, and 0.6 ± 0.05 (all p < 0.0001). Symptom scores of itching and burning also reduced significantly from 6.9 ± 0.1 to 4.5 ± 0.1 to 1.5 ± 0.05 and 1.0 ± 0.05 (both p < 0.0001). Severity of erythema and scaling was also significantly reduced from 5.5 ± 0.1 and 7.0 ± 0.1, respectively, to 1.3 ± 0.05 and 1.6 ± 0.05 (both p < 0.0001). Tolerability and subject satisfaction were both excellent. There were no significant differences in treatment effect, tolerability, or subject satisfaction between men and women. Discussion/Conclusion Replacing current shampooing practices with a broad-spectrum cannabidiol-containing shampoo significantly reduces both severity and symptoms of scalp inflammation within 2 weeks, with excellent tolerability and treatment satisfaction in subjects with mild to moderate scalp psoriasis or seborrheic dermatitis.

Abstract
Although antiepileptic drugs (AEDs) are mainstay of the treatment of epilepsy, they are associated with significant adverse effects. The present study reviews the adverse effects of AEDs on some of the nutrition-related issues, including bone health, body weight, glucose and lipid metabolism, vitamin homeostasis, antioxidant defense system, and pregnancy. This paper also provides some nutritional recommendations for people with epilepsy. Patients with epilepsy should be regularly evaluated with regard to their nutrition status and any possible nutritional problems. Daily intake of adequate amounts of all nutrients from various sources should be encouraged, especially for vulnerable groups such as children, adolescents, elderly, and pregnant women. When necessary, preventative or therapeutic supplementation with appropriate micronutrients could be helpful. Graphical abstract.

Abstract
Stem cells can differentiate to diverse cell types in our body, and they hold great promises in both basic research and clinical therapies. For specific stem cell types, distinctive nutritional and signaling components are required to maintain the proliferation capacity and differentiation potential in cell culture. Various vitamins play essential roles in stem cell culture to modulate cell survival, proliferation and differentiation. Besides their common nutritional functions, specific vitamins are recently shown to modulate signal transduction and epigenetics. In this article, we will first review classical vitamin functions in both somatic and stem cell cultures. We will then focus on how stem cells could be modulated by vitamins beyond their nutritional roles. We believe that a better understanding of vitamin functions will significantly benefit stem cell research, and help realize their potentials in regenerative medicine.

Abstract
BACKGROUND: Biotin is popular in hair loss treatment supplements, although the frequency of its deficiency in patients with hair loss has not been established. OBJECTIVES: This work sought to assess the serum levels of biotin in patients with telogen effluvium. METHODS: This case-control study included 60 patients with telogen effluvium and 20 control subjects. Subjects who were on biotin therapy three months prior to the study and those reporting other causes of hair loss were excluded. The scalp of each patient was clinically and dermoscopically examined. Serum biotin levels were measured using enzyme-linked immunosorbent assay kits. RESULTS: Serum levels of biotin were optimal in patients and control groups with no significant difference between the groups. Insignificantly lower biotin levels in elderly patients, smokers, athletes, those with a history of recurrent infections, and women who were pregnant and/or lactating were observed. There was also an insignificant positive correlation between the serum level of biotin and patient age and an insignificant negative correlation between disease duration and patient body mass index. Serum biotin has a weak specificity and sensitivity in differentiating between cases and control subjects or between acute and chronic telogen effluvium. CONCLUSION: There was no significant difference in serum biotin levels between cases and controls or between those with acute or chronic telogen effluvium.

Abstract
BACKGROUND & AIMS Biotin is a water-soluble vitamin that is indispensable for human health. Biotin deficiency can cause failure-to-thrive, immunodeficiency, alopecia, dermatitis, and conjunctivitis. We previously reported that biotin deficiency also can lead to severe colitis in mice, which is completely reversed with supplementation. Our aim in this study was to determine if high-dose biotin supplementation can provide a therapeutic benefit in a preclinical model for inflammatory bowel disease (IBD) and to identify the molecular mechanism by which this occurs. METHODS Mice were challenged with dextran sodium sulfate to induce colitis and were treated with 1 mmol/L biotin to induce or maintain remission. Clinical response was monitored by the Disease Activity Index and fecal calprotectin levels. The colon tissue was investigated for histology, length, as well as expression of inflammatory cytokines (interleukin 6, tumor necrosis factor-α, interleukin 1β), intestinal permeability, tight junctions (zonula occludens-1 and claudin-2), and the transcription factor nuclear factor-κB (NF-κB). RESULTS Biotin therapy led to delayed onset and severity of colitis as well as accelerated healing. There was improvement in the Disease Activity Index, fecal calprotectin levels, colon length, and histology. In addition, biotin-treated mice had reduced expression of inflammatory cytokines, reduced intestinal permeability, and reduced activation of NF-κB. CONCLUSIONS Oral supplementation with biotin provides benefit for maintenance and induction of remission in the dextran sodium sulfate preclinical model for IBD. Biotin does this by reducing the activation of NF-κB, which prevents the production of inflammatory cytokines and helps maintain the integrity of the intestinal barrier. Clinically, the NF-κB pathway is important in the development of IBD and this finding suggests that biotin may have therapeutic potential for patients with IBD.

Abstract
To revitalize the antibiotic pipeline, it is critical to identify and validate new antimicrobial targets1. In Mycobacteria tuberculosis and Francisella tularensis, biotin biosynthesis is a key fitness determinant during infection2-5, making it a high-priority target. However, biotin biosynthesis has been overlooked for priority pathogens such as Acinetobacter baumannii, Klebsiella pneumoniae and Pseudomonas aeruginosa. This can be attributed to the lack of attenuation observed for biotin biosynthesis genes during transposon mutagenesis studies in mouse infection models6-9. Previous studies did not consider the 40-fold higher concentration of biotin in mouse plasma compared to human plasma. Here, we leveraged the unique affinity of streptavidin to develop a mouse infection model with human levels of biotin. Our model suggests that biotin biosynthesis is essential during infection with A. baumannii, K. pneumoniae and P. aeruginosa. Encouragingly, we establish the capacity of our model to uncover in vivo activity for the biotin biosynthesis inhibitor MAC13772. Our model addresses the disconnect in biotin levels between humans and mice, and explains the failure of potent biotin biosynthesis inhibitors in standard mouse infection models.

Abstract
One of the most common micronutrient deficiencies with cutaneous findings is the vitamin B, also known as biotin, deficiency. Biotin deficiency may be due to congenital lack of biotinidase, or acquired following some conditions that interfere with its absorption, such as inflammatory bowel disorders, a diet too rich in avidin, magnesium deficiency, smoking habit and treatment with broad-spectrum antibiotics, anticonvulsants and sulfonamides. This review highlights the role of biotin in the most common skin disorders such associated with biotin deficiency and an approach to their treatment. Biotin administration may improve the treatment of hair loss when deficiency is detected on the basis of a careful patient history, clinical examination and the determination of serum biotin levels. The use of biotin is rationale in seborrheic dermatitis as the vitamin intercepts the main metabolic pathways underlying the pathogenesis of the disease. Treatment with biotin could also be useful in comedonal acne characterized by a high rate of seborrhea, and may be helpful for acne treated with topical retinoids, contributing to the control of flaking and irritation. The tolerability of biotin is excellent and there is no risk of hypervitaminosis even in the case of high doses. It is important that administration is controlled by physicians and follows a medical diagnosis and prescription. Correct doses used in dermatological conditions are safe and are not at risk of interference with laboratory tests.

Abstract
A universal definition of myocardial infarction (UDMI) has been established, periodically updated, and refined over the past twenty years. The primary purpose of the UDMI is to bring uniformity and accuracy to clinical diagnosis. Herein, a review and analysis of the UDMI is presented with emphasis on clinicopathological correlation. Determination of the presence of myocardial injury is based on the detection of abnormal serum cardiac biomarkers, particularly cardiac troponin (cTn), and in the current fourth iteration of the UDMI, high sensitivity (hs)-cTn. Differentiation of myocardial infarction from other causes of myocardial injury requires the documentation of clinical evidence of myocardial ischemia. In this review, difficulties in applying the UDMI in actual practice are discussed, based on the experience and perspective of those of us who face these problems as part of our own practice of pathology. The complexity in application of the UDMI is highlighted by the presentation of five illustrative cases involving the differential diagnosis of myocardial injury and myocardial infarction due to atherothrombotic and nonatherothrombotic coronary artery disease. The cases include myocardial infarction due to severe coronary atherosclerosis, supply-demand mismatch, coronary artery dissection associated with an eosinophilic coronary periarteritis, and coronary thromboembolism, and a case with a differential diagnosis of myocarditis and myocardial infarction. These cases illustrate how pathological findings can contribute to more accurate application of the UDMI and how, when critically applied, the UDMI can be used to better characterize myocardial infarcts in clinical practice.

Abstract
BACKGROUND Male androgenetic alopecia (MAGA) is caused by the conversion of the terminal to vellus hair. Zinc is one of the most studied trace elements in hair disorders and biotin is one of the most prescribed supplement for its treatment. OBJECTIVES The study aimed to evaluate serum zinc and biotin levels in MAGA patients to answer the question if there is a value to add zinc or biotin as a supplements in the MAGA treatment. PATIENTS AND METHODS Sixty MAGA patients and 60 age, sex, and body mass index-matched healthy volunteers were included. We measured serum biotin and zinc in all participants. RESULTS Zinc (µg/dL) was lower significantly in patients compared to controls (P = 0.01), suboptimal biotin (ng/L) levels were in patients, and within normal values in controls (P = 0.01). A positive significant correlation was found between serum zinc and serum biotin (r = 0.489, P = 0.001). Serum zinc and biotin showed a nonsignificant correlation with age and disease duration. A non-significant relation was obtained between the MAGA grades, and zinc (P = 0.485) and biotin levels (P = 0.367). CONCLUSIONS Serum zinc showed subnormal value and adding zinc supplement in MAGA treatment is recommended. Serum biotin showed a suboptimal level in MAGA patients that is not correlated with patients' age or disease severity. Biotin supplement in MAGA treatment may add value to hair quality and texture. We recommend future biotin evaluation in serum combined with its metabolites in MAGA patients' urine.

Abstract
Polycystic ovarian syndrome (PCOS) is one of the most common endocrine disorders in women of both developed and developing countries. It is associated with insulin resistance, hyperinsulinemia, hyperandrogenism, oxidative stress and various long-term complications. The present study was undertaken to evaluate the efficacy and safety of the supplementation (Trazer F ForteTM-CORONA Remedies Pvt. Ltd.) providing combination of insulin sensitising agents (myo-inositol, D-chiro-inositol and chromium picolinate), antioxidants (N-acetylcysteine and lycopene) and vitamins (vitamin D, biotin and folic acid) in women with PCOS. After 12 weeks of supplementation, a significant improvement was observed in menstrual cyclicity, acne and hirsutism in both obese and lean PCOS patients. A significant reduction was observed in body weight and BMI of obese subjects. However, both parameters remain unchanged in lean subjects. We suggest that combination therapy of insulin sensitising agents, antioxidants and vitamins may be a fruitful approach for the management of PCOS.Impact statementWhat is already known on this subject? Monotherapy of insulin sensitising agents, antioxidants and vitamins is beneficial in the treatment of PCOS.What do the results of this study add? Combined use of insulin sensitising agents (myo-inositol, D-chiro-inositol and chromium picolinate), antioxidants (N-acetylcysteine and lycopene), and vitamins (vitamin D, biotin and folic acid) is safe and effective in obese and non-obese women with PCOS.What are the implications of these findings for clinical practice and/or further research? Since PCOS is a multifactorial and a complex endocrine disorder, combination therapy can be used for the comprehensive management of PCOS.

Abstract
People commonly inquire about vitamin and mineral supplementation and diet as a means to prevent or manage dermatological diseases and, in particular, hair loss. Answering these queries is frequently challenging, given the enormous and conflicting evidence that exists on this subject. There are several reasons to suspect a role for micronutrients in non-scarring alopecia. Micronutrients are major elements in the normal hair follicle cycle, playing a role in cellular turnover, a frequent occurrence in the matrix cells in the follicle bulb that are rapidly dividing. Management of alopecia is an essential aspect of clinical dermatology given the prevalence of hair loss and its significant impact on patients' quality of life. The role of nutrition and diet in treating hair loss represents a dynamic and growing area of inquiry. In this review we summarize the role of vitamins and minerals, such as vitamin A, vitamin B, vitamin C, vitamin D, vitamin E, iron, selenium, and zinc, in non-scarring alopecia. A broad literature search of PubMed and Google Scholar was performed in July 2018 to compile published articles that study the relationship between vitamins and minerals, and hair loss. Micronutrients such as vitamins and minerals play an important, but not entirely clear role in normal hair follicle development and immune cell function. Deficiency of such micronutrients may represent a modifiable risk factor associated with the development, prevention, and treatment of alopecia. Given the role of vitamins and minerals in the hair cycle and immune defense mechanism, large double-blind placebo-controlled trials are required to determine the effect of specific micronutrient supplementation on hair growth in those with both micronutrient deficiency and non-scarring alopecia to establish any association between hair loss and such micronutrient deficiency.Plain Language Summary: Plain language summary available for this article.

Abstract
The treatment of alopecia is limited by a lack of therapies that induce and sustain disease remission. Given the negative psychosocial impact of hair loss, patients that do not see significant hair restoration with conventional therapies often turn to complementary and alternative medicine (CAM). Although there are a variety of CAM treatment options on the market for alopecia, only a few are backed by multiple randomized controlled trials. Further, these modalities are not regulated by the Food and Drug Administration and there is a lack of standardization of bioactive in gredients in over-the-counter vitamins, herbs, and supplements. In this article, we provide a comprehensive review of the efficacy, safety, and tolerability of CAM, including natural products and mind and body practices, in the treatment of hair loss. Overall, there is a need for additional studies investigating CAM for alopecia with more robust clinical design and standardized, quantitative outcomes.

Abstract
Alopecia, a frequently reported problem, severely impacts the quality of life of patients and is often associated with loss of confidence and low self-esteem. Several conditions such as telogen effluvium (TE), anagen effluvium, diffuse type of alopecia areata, female pattern hair loss, hair shaft abnormalities, loose anagen hair syndrome, and congenital atrichia or hypotrichosis are associated with hair loss. The actual prevalence rate of TE is not reported since most cases are subclinical in nature. Further, since women get more distressed by hair fall and promptly seek treatment, they tend to be over-represented. However, both genders can suffer from this condition if triggering factors are present. This consensus paper was developed by taking into account opinions of renowned experts in the field and is hoped to serve as an evidence-based platform for selecting efficacious and safe therapy for patients with TE. This review presents a synopsis of the key opinions of experts on all aspects of treatment and effective management of this condition.

Abstract
BACKGROUND Although biotin interferences in TSH, FT3, FT4, and other biotinylated antibody-based assays manufactured by Roche Diagnostics have been well studied, there are relatively few reports on biotin interference in biotin-based assays manufactured by other companies. We investigated biotin interferences in TSH, FT4, and FT3 assays based on the LOCI (luminescent oxygen channeling assay) technology using the Dimension Vista 1500 analyzer (Siemens). METHODS We prepared four serum pools using leftover specimens. Three serum pools were prepared initially for the original study but the 4th pool was prepared three months later. The aliquots of serum pool one and two were supplemented with various amounts of biotin (50 -1200 ng/mL) followed by determination of TSH, FT4, and FT3 concentrations. The aliquots of third pool were also supplemented with biotin to investigate whether 1:3 dilution could identify biotin interference. Aliquots of serum pool four were supplemented with biotin in order to study reproducibility of our original data. RESULTS We observed significantly elevated FT3 levels at biotin concentration of 100 ng/mL. In contrast, FT4 levels were falsely elevated but TSH levels were falsely decreased at a biotin level of 500 ng/mL. We also observed nonlinearity in dilution experiment. CONCLUSIONS We conclude that FT3 assay is most susceptible to biotin interference (threshold: 100 ng/mL) while the FT4 and TSH assays are less affected (threshold: 500 ng/mL). In addition, we also observed nonlinearity upon 1:3 dilution, which may indicate biotin interference (or interference from other compounds).

Abstract
Purpose Telogen effluvium (TE) is defined as a diffuse hair loss characterized by shortening of the anagen phase and precipitation of the telogen phase, with a consequent reduction of total hair volume. Nutritional supplementation is indicated under conditions in which TE is related to dietary disorders. The aim of this clinical study was to compare the efficacy of two different supplements in monotherapy for TE. Patients and methods Female adult patients were randomized to receive two oral nutritional supplements (group 1: a supplement composed of zinc, biotin, iron, vitamins A, C, E, and B complex, folic acid, magnesium, and amino acids of keratin and collagen and group 2: calcium pantothenate cystine, thiamine nitrate, medicinal yeast, keratin, and aminobenzoic acid) to treat hair loss for 180 days. They were evaluated clinically and by digital trichoscopy. Results Clinical evaluation showed significant clinical improvement (P<0.05) for the evaluated parameters: hair loss, hair volume, density of hair (scalp cover), hair shine, hair strength, in 180 days. At 90 days evaluation, group 1 showed significant improvement for all parameters, while group 2 did not show any significant improvement for hair shine and hair strength. In the digital trichoscopy, there was a significant improvement only in group 1 (11.09%×7.76%) after 180 days. Conclusion In idiopathic TE, the nutritional component should be suspected; the supplementation of an association of nutrients in recommended daily intake can lead to significant improvement of the condition from the first trimester of use. The use of an association with proven efficacy and a safety profile and posologic convenience facilitate its indication and patient adherence.

Abstract
Nutrition plays a critical role in the manifestation and management of inflammatory pilosebaceous disorders. There is rich potential for insight into the impact of dietary effects on the pathophysiology of inflammatory pilosebaceous disorders including acne vulgaris, hidradenitis suppurativa, rosacea, and the closely related seborrhoeic dermatitis. Acne vulgaris and hidradenitis suppurativa are thought to have similar diet-modulating pathogenic pathways. Western diet influences Acne vulgaris and hidradenitis suppurativa by increasing insulin and modulating FOX01/mTOR, resulting in over-expression of cytokeratins, hyperproliferation of keratinocytes, and hypercornification of the follicular wall. Key receptors in rosacea are alternatively activated by UV radiation, hot beverages, spicy foods, vanilla, cinnamon, caffeine, alcohol, cold temperatures, and niacin- and formalin-containing foods, to increase oedema and flushing, resulting in erythema, telangiectasia, and warmth, characteristic features of the condition. Seborrhoeic dermatitis, while not a follicular disorder, is closely related, and can be modulated by dietary influences, such as biotin and probiotics. This overview summarizes the role that nutrition plays on these disorders, and identifies dietary modifications as potential adjunctive therapies.

Abstract
Molecularly Imprinted Polymers (MIPs) are synthetic receptors that are able to selectively bind their target molecule and, for this reason, they are currently employed as recognition elements in sensors. In this work, MIP nanoparticles (nanoMIPs) are produced by solid-phase synthesis for a range of templates with different sizes, including a small molecule (biotin), two peptides (one derived from the epithelial growth factor receptor and vancomycin) and a protein (trypsin). NanoMIPs are then dipcoated on the surface of thermocouples that measure the temperature inside a liquid flow cell. Binding of the template to the MIP layer on the sensitive area of the thermocouple tip blocks the heat-flow from the sensor to the liquid, thereby lowering the overall temperature measured by the thermocouple. This is subsequently correlated to the concentration of the template, enabling measurement of target molecules in the low nanomolar regime. The significant improvement in the limit of detection (a magnitude of three orders compared to previously used MIP microparticles) can be attributed to their high affinity, enhanced conductivity and increased surface-to-volume ratio. It is the first time that these nanosized recognition elements are used in combination with thermal detection, and it is the first report on MIP-based thermal sensors for determining protein levels. The developed thermal sensors have a high selectivity, fast measurement time (<5 min), and data analysis is straightforward, which makes it possible to monitor biomolecules in real-time. The set of biomolecules discussed in this manuscript show that it is possible to cover a range of template molecules regardless of their size, demonstrating the general applicability of the biosensor platform. In addition, with its high commercial potential and biocompatibility of the MIP receptor layer, this is an important step towards sensing assays for diagnostic applications that can be used in vivo.

Abstract
Aim: Biotin in human serum is a potential interfering factor for streptavidin-biotin-based assays. We aimed to evaluate the effective half-life of biotin and biotin metabolites, and establish a pharmacokinetic (PK) model to simulate the time taken for the biotin concentration to fall below a series of thresholds. Materials & methods: PK properties of biotin (5, 10 and 20 mg daily) were evaluated in healthy participants. Biotin serum concentrations were simulated for high-dose regimens (1 mg daily to 300 mg q.i.d.) using a population PK model. Results: Washout periods required for biotin concentrations to reach thresholds ranging from 10 to 100 ng/ml were successfully simulated. Conclusion: Our simulations provide valuable guidance on biotin washout periods necessary to avoid false assay results.

Abstract
Tiger nut (Cyperus esculentus L.) is a crop traditionally grown in Valencia Region (Spain) and other temperate and tropical regions in the world, where its tubers are commonly consumed as tiger nut milk (horchata). Because of their nutritive potential and original taste, these products are beginning to spread internationally and, as consequence, analytical procedures to assess nutritional profiles, quality control issues are acquiring increasing relevance. The main objective of this study was to use an advance analytical method and chemometrics tools to determine if the ultra-high temperature (UHT) treatment necessary to extend the shelf life of tiger nut milk would affect the profile of nutrients when compared to fresh product. A cold solvent extraction followed by liquid chromatography coupled with high resolution mass spectrometry (UHPLC-HRMS) was used. Datasets obtained from UHT and fresh tiger nut milk data were analyzed through an untargeted metabolomics approach to compare chemical patterns, highlighting differences in citric acid esters of mono- diglycerides (CITREM) and monoacylglycerol (MAG) used as emulsifiers of UHT products, and a remarkably higher abundance of biotin, phosphatidic acid (PA) and L-arginine in fresh products. These results showed that untargeted metabolomics through high resolution tandem mass spectrometry allowed fine differences between food products to be found, therefore, the nutrient lost caused by UHT treatment was clearly discerned.
