Abstract
Following a request from the European Commission, the EFSA Panel on Nutrition, Novel Foods and Food Allergens (NDA) was asked to deliver an opinion on vitamin D2 mushroom powder as a novel food (NF) pursuant to Regulation (EU) 2015/2283. The NF is produced from Agaricus bisporus mushroom powder that has been exposed to ultraviolet (UV) irradiation to induce the conversion of provitamin D2 (ergosterol) to vitamin D2 (ergocalciferol). The NF contains concentrations of vitamin D in the form of vitamin D2 in the range of 245-460 μg/g. The information provided on the production process, composition and specifications of the NF does not raise safety concerns. The applicant intends to add the NF as an ingredient in a variety of foods and beverages in amounts that result in either 1.2 or 2.4 μg vitamin D2 per 100 g or 100 mL of the food as consumed. The applicant also intends to add the NF in food supplements at a maximum of 15 μg vitamin D2/day for individuals above 1 year of age, as well as in foods for special medical purposes (FSMPs). The estimates for combined intake of vitamin D from the NF, the background diet and fortified foods, were below the ULs for vitamin D as established previously by the NDA Panel for children, adolescents and adults, i.e. 50 and 100 μg/day. The estimated combined vitamin D intake in infants (6-12 months) is also below the UL for vitamin D of 35 μg/day. The Panel considers that taking into account the composition of the NF and the proposed conditions of use, the consumption of the NF is not nutritionally disadvantageous for the proposed target population. The Panel concludes that the NF is safe under the proposed conditions of use.

Triple quadrupole liquid chromatography-mass spectrometry-mediated evaluation of vitamin D 2 accumulation potential, antioxidant capacities, and total polyphenol content of white jelly mushroom ( Tremella fuciformis Berk.). Mycologia 2024; 116:464-474. [PMID: 38489159 DOI: 10.1080/00275514.2024.2313435] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/28/2023] [Accepted: 01/30/2024] [Indexed: 03/17/2024]
Abstract
Tremella fuciformis Berk. (TF), or the white jelly mushroom, is well known for its myriad of pharmacological properties, such as immunomodulatory, anti-inflammatory, antidiabetic, antitumor, and antioxidant activities, and hypocholesterolemic and hepatoprotective effects that boost human health. Most of the studies of TF are concentrated on its polysaccharide (glucuronoxylomannan) composition, which is responsible for its pharmacological as well as rheological properties. It is well established that mushrooms are a great source of dietary vitamin D due to the presence of ergosterol in their cell membrane. There is a lack of published data on TF as a source of vitamin D2. Therefore, this study aimed to evaluate the vitamin D2 composition of the fruiting bodies of TF using triple quadrupole liquid chromatography-mass spectrometry (LC-MS/QQQ). The results showed highest vitamin D2 content (292.02 µg/g dry weight) in the sample irradiated with ultraviolet B (UVB; 310 nm) for 180 min as compared with the control group (52.47 µg/g dry weight) (P ≤ 0.001). The results showed higher accumulation potential of vitamin D2 in TF as compared with published data available for other extensively studied culinary mushrooms, such as Agaricus bisporus, Lentinula edodes, Pleurotus ostreatus, Cordiceps militaris, and Calocybe indica. Moreover, the impact of UV treatment on antioxidant capacities and total polyphenol content of TF was also studied. The accumulation potential of vitamin D in TF reveals a novel commercial source for this nutrient.

Abstract
Introduction To detect the relationship between 25-hydroxy vitamin D (25(OH)D) and adolescents' parathyroid hormone (PTH) and bone mineral density (BMD). Material and methods Two hundred adolescent girls were recruited for this cross-sectional comparative study. After detailed evaluation, a pelvic sonography was performed for the studied adolescents to rule out any pelvic pathology. Adolescents' blood samples were collected to measure the thyroid stimulating hormone, prolactin, glycosylated haemoglobin (HbA1C), PTH, and 25(OH)D. The studied adolescents' BMD and the T-score were evaluated at 2 anatomical sites. The studied adolescents were classified according to their serum 25(OH)D into 2 groups: a 25(OH)D-deficient group (study group; 25(OH)D < 20 ng/ml) and normal controls (25(OH)D > 30 ng/ml). Student's t-test was used for analysis of the studied adolescents' variables, and correlation analysis (Pearson`s correlation) was used to detect the relationship between 25(OH)D and adolescents' PTH and BMD. Results The parathyroid hormone was statistically higher in the 25(OH)D-deficient group than in the normal controls (41.3 ±3.4 pg/ml vs. 21.1 ±2.8) (p = 0.02), and the BMD was statistically lower in the 25(OH)D-deficient group than in the normal controls (-1.25 ±0.5 vs. 0.3 ±0.4) (p = 0.01). The 25(OH)D had a significant negative correlation with the adolescents' PTH (r = -0.9175; p < 0.00001) and a significant positive correlation with the adolescents' BMD (r = 0.756; p < 0.00001). The parathyroid hormone had a significant negative correlation with the adolescents' BMD (r = -0.7006; p < 0.00001). Conclusions The parathyroid hormone in this study had significant negative correlations with both 25(OH)D and BMD. The 25(OH)D had a significant positive correlation with the studied adolescents' BMD.

CURRENT HEALTH SCIENCES JOURNAL 2024; 50:87-93.

Abstract
Owing to ergosterol content, after UV irradiation yeast become a well-known source of ergocalciferol (vitamin D2). Additionally, pharmaceutical yeast-based supplements may represent a suitable option for treating hypovitaminosis, especially in patients adhering to a vegan diet. Using the high-performance liquid chromatography-ultraviolet (HPLC-UV) methodology our study sought to analyse three commercially available yeast-based vitamin D2 supplements while comparing the effect of UV-C irradiation (254 nm) on yeast biomass derived from the brewing process and pure ergosterol. The two compounds were precisely separated under the described conditions in an efficient and quick manner with a retention time (Rt) of 4.152 ± 0.018 minutes for vitamin D2 and 5.097 ± 0.013 minutes for ergosterol. However, when approaching the quantitative analysis, based on our findings, it appears that the pharmaceutical supplements deviate from the declared amount of substance indicated on the label. 15 minutes of UV-C irradiation generates vitamin D2 in yeast biomass with a conversion rate of 1.78%. Also, high content of ergosterol, beside vitamin D2 formation after irradiation, may trigger the appearance of secondary products such as tachysterol.

Abstract
Introduction To detect the relationship between 25(OH)D and hypothyroidism in adolescents. Material and methods A total of 180 adolescents were included in the current study, which was conducted in West Kazakhstan (Aktobe) over 2 years. After thorough evaluation, blood samples were collected from the studied participants to measure the thyroid stimulating hormone (TSH), free thyroxine (T4), prolactin, glycosylated haemoglobin, and 25(OH)D. Participants were classified into a 25(OH)D-deficient group (study group) and controls. MedCalc and correlation analysis (Pearson's correlation) were used to detect the odds of hypothyroidism and the relationship between 25(OH)D and adolescents' hypothyroidism, respectively. Results Thyroid-stimulating hormone was statistically higher in the 25(OH)D-deficient group than in the normal controls (3.71 ±1.4 mIU/ml vs. 2.67 ±0.99) (p = 0.0006), and the free T4 was statistically lower in the 25(OH)D-deficient group than in normal controls (1.4 ±0.56 ng/ml vs. 1.5 ±0.4) (p = 0.0008). The 25(OH)D deficient group had higher odds of subclinical (OR 4.89; p = 0.016), and clinical hypothyroidism (OR 4.3; p = 0.013) compared to controls. A significant negative correlation between the 25(OH)D and TSH (r = -0.793; p < 0.00001), and a significant positive correlation between the 25(OH)D and free T4 (r 0.55; p < 0.00001) were detected in this study. Conclusions The thyroid-stimulating hormone was statistically higher and the free T4 was statistically lower in the 25(OH)D-deficient group than in normal controls. The 25(OH)D-deficient group had higher odds of both subclinical and clinical hypothyroidism compared to controls. A significant negative correlation between the 25(OH)D and TSH, and a significant positive correlation between the 25(OH)D and the free T4 were detected in this study.

Abstract
Introduction To detect whether there is a relation between vitamin D (Vit. D) and adolescents' serum prolactin (PRL) or not. Material and methods Hundred and seventy-six adolescent girls were recruited for the current study, which was conducted in West Kazakhstan (Aktobe) over two years. After thorough evaluation, blood samples were taken from adolescents to measure thyroid stimulating hormone (TSH), free thyroxine (T4), PRL, glycosylated hemoglobin and 25(OH)D. The studied adolescents were classified into study group [25(OH)D deficient] and controls [normal 25(OH)D]. The acquired adolescents' variables were analyzed using the Student t-test and Pearson's correlation. Results The serum TSH and PRL were statistically higher in the study group than normal controls (3.73 ±1.45 mIU/ml and 47.5 ±7.6 ng/ml vs. 2.67 ±1.0 and 10.8 ±5.1, respectively), (p = 0.0003 and p = 0.0001, respectively). The free T4 was statistically lower in the study group than normal controls (1.4 ±0.6 ng/ml vs. 1.5 ±0.4), (p = 0.0001). Strong negative associations between the serum PRL and 25(OH)D [r = -0.803 (p < 0.00001)], and between the serum PRL and free T4 [r = -0.6959 (p < 0.00001)] were detected in this study. Additionally, there was a strong positive association between the serum PRL and TSH [r = 0.8137 (p < 0.00001)]. Conclusions A strong negative association between the serum PRL and 25(OH)D and a strong positive association between the serum PRL and TSH were detected in this study. This study recommends further studies to confirm the relation between Vit. D and PRL and screening Vit. D deficient adolescents for PRL and thyroid disorders.

Abstract
Vitamin D receptor (VDR) expression in the female reproductive tract explains the regulatory role of vitamin D on inflammatory cytokine and prostaglandin (PGD) synthesis. This study aimed to evaluate the effect of vitamin D on adolescents' primary dysmenorrhea and the relationship between Vit. D and adolescents' primary dysmenorrhea. Eighty-five adolescents were included in the current study. After a detailed evaluation, pelvic sonography was performed for all participants to rule out any pelvic pathology. Blood samples were collected to measure thyroid stimulating hormone (TSH), prolactin, glycosylated hemoglobin (HbA1C), and 25-hydroxyvitamin D (25[OH]D). Participants were administered vitamin D (50,000 IU weekly for five months), and their dysmenorrhea symptoms were evaluated before and after this period using the Visual Analog Scale (VAS) and the Verbal Multidimensional Scoring (VMS). The mean VAS and VMS scores of dysmenorrhea statistically decreased from 8.7±0.91 and 2.65±0.93 to 4.8±0.75 and 0.80±0.75, respectively, after vitamin D intake (p=0.03 and 0.025, respectively). Significant negative associations between 25(OH)D and VAS (R = -0.886; p<0.00001) and VMS of dysmenorrhea (R = -0.885; p<0.00001) were detected in this study. Vit. D could be a useful therapeutic option to reduce the severity of primary dysmenorrhea and could limit the use of non-steroidal anti-inflammatory drugs.

Abstract
Terrestrial organisms and ecosystems are being exposed to new and rapidly changing combinations of solar UV radiation and other environmental factors because of ongoing changes in stratospheric ozone and climate. In this Quadrennial Assessment, we examine the interactive effects of changes in stratospheric ozone, UV radiation and climate on terrestrial ecosystems and biogeochemical cycles in the context of the Montreal Protocol. We specifically assess effects on terrestrial organisms, agriculture and food supply, biodiversity, ecosystem services and feedbacks to the climate system. Emphasis is placed on the role of extreme climate events in altering the exposure to UV radiation of organisms and ecosystems and the potential effects on biodiversity. We also address the responses of plants to increased temporal variability in solar UV radiation, the interactive effects of UV radiation and other climate change factors (e.g. drought, temperature) on crops, and the role of UV radiation in driving the breakdown of organic matter from dead plant material (i.e. litter) and biocides (pesticides and herbicides). Our assessment indicates that UV radiation and climate interact in various ways to affect the structure and function of terrestrial ecosystems, and that by protecting the ozone layer, the Montreal Protocol continues to play a vital role in maintaining healthy, diverse ecosystems on land that sustain life on Earth. Furthermore, the Montreal Protocol and its Kigali Amendment are mitigating some of the negative environmental consequences of climate change by limiting the emissions of greenhouse gases and protecting the carbon sequestration potential of vegetation and the terrestrial carbon pool.
