RESUMO

BACKGROUND: Parents/caregivers of children with developmental disabilities (CDD) have a wide range of support needs and there are various interventions available. Support, challenges, and needs among parents/caregivers of CDD likely vary in different geographical settings. This study aimed to analyze the perceptions of support, challenges, and needs among parents/caregivers of CDD in Croatia, North Macedonia, and Serbia. METHODS: We conducted a cross-sectional study in March-April 2023 within the Erasmus + SynergyEd project. The eligible participants were parents and caregivers of CDD in Croatia, North Macedonia, and Serbia, who filled out a modified Caregiver Needs Survey online. RESULTS: Among 953 participants, 542 (57%) were from Croatia, 205 (21%) were from North Macedonia and 206 (22%) were from Serbia. The most common diagnosis of participants' children was autism spectrum disorder (26%). The child most often received the first diagnosis at the median of 2 years, diagnosed by a team of professionals. More than half (58%) of children attended preschool and public school, while 22% did not attend any schooling. Additional support from the state/city/county was received by 66% of CDD. Most participants declared not participating in association/organization for family support. Participants mostly (68%) used experts who work with the child as a source of information about their child's condition, followed by the Internet (53%). In the last 12 months, 60% of participants had difficulties with the availability of services in their area or problems getting appointments. The biggest problem in getting support was ensuring the child's basic rights were protected. Participants stated that ensuring greater rights for CDD was the greatest need for their families. CONCLUSION: Parents/caregivers of CDD in Croatia, North Macedonia, and Serbia faced multiple challenges, but most of them were satisfied with the services provided to their children. Future efforts to develop policies and services related to CDD should consider the opinions of their parents/caregivers and disparities in access to services.

RESUMO

BACKGROUND: Type 2 diabetes mellitus (T2DM) is commonly associated with hyperglycemia, dyslipidemia, oxidative stress and inflammation which are well known cardiovascular risk factors. Pomegranate peel polyphenols have a proven hypolipemic, antioxidant and anti-inflammatory activity. However, there is a lack of clinical studies that would confirm its antioxidant and anti-inflammatory effects in diabetic patients. The potential of pomegranate peel extract (PoPEx) to counteract inflammation and oxidative stress in T2DM patients was investigated. For this purpose, a randomized, double-blind placebo-controlled study involving adult T2DM patients treated with PoPEx or placebo for eight-weeks was conducted. METHODS: Patients were randomly divided into two groups: the first group (n = 30) received capsules containing PoPEx 250 mg twice daily, while the placebo group (n = 30) received placebo capsules twice daily. Plasma concentration of inflammatory factors (interleukin 6 (IL-6), tumor necrosis factor α (TNF-α) and high sensitivity C reactive protein (hsCRP)), oxidative stress biomarkers (thiobarbituric acid reactive substances (TBARS), nitrites (NO2-), superoxide anion radical (O2-), hydrogen peroxide (H2O2), total antioxidant capacity (TAC)), homocysteine and lipid profile were analyzed. RESULTS: The PoPEx treatment showed a significant reduction of inflammatory factors (IL-6, TNF-α, hsCRP), oxidative stress biomarkers (TBARS, NO2-, O2-) and homocysteine, while the TAC was increased. Moreover, a significant improvement in lipid profile was observed in the PoPEx group. Additional analysis showed a significant inverse correlation between the decrements of all measured inflammatory markers and TAC in the PoPEx group. CONCLUSIONS: The study demonstrated that eight-week-long PoPEx administration had favorable effects on inflammatory status and oxidative stress biomarkers in diabetic patients.

RESUMO

OBJECTIVES: Industrially produced trans fatty acid (iTFA) have adverse health effects and thus their consumption should be limited. The aim of this study was to determine and compare the iTFA content in frequently consumed food products by young adults from the Serbian and Slovenian market with supposedly elevated iTFA content in 2015. At the time of this study, there was no recommended limit of iTFA in both countries, and reduction of iTFA in foods was on voluntary basis. METHODS: We determined iTFA content in food products, 19 from the Serbian and 22 from the Slovenian market, blinded and analysed in the same analytical run. Contents of fatty acids (FA) methyl esters were analysed by capillary gas chromatography with a flame ionisation detector. Heptadecanoic acid was used as internal standard. Individual FA along with TFA were expressed as percentages of total measured FA. The amount of each FA in the sample was then calculated from the response factor and the transformation factor of the FA from the FA methyl ester content. RESULTS: Elaidic acid (C18:1t) was found as the most abundant TFA in analysed products, ranging from 0.52 g/100 g of total FA in chocolate candy up to 60.4 g/100 g in a salami from Serbian market. In Slovenian products, the values for elaidic acid were lower, 0.04-3.95 g/100 g of total FA, except in one type of wafers (24.3 g/100 g). CONCLUSIONS: The majority of analysed products from the Serbian and three from Slovenian market exceeded the recommended WHO and EU limit of 2% iTFA of total fat in foods. Samples of frequently consumed salami, wafers, tea biscuits, and snacks were identified as products with potentially higher burden of iTFA in diets of young adults in Serbia.

RESUMO

Polyunsaturated fatty acid (PUFA) dietary intake, status and serum key fatty acid (FA) ratios may aid in cardiovascular disease-related risk assessment. The aim of this study was to investigate the effects of lipid-lowering diet on key FA ratios in serum phospholipids and omega-3 index in erythrocyte phospholipids in moderately hyperlipidemic subjects. The study included 41 subjects, mean age 56±6 years. Nutritional habits were evaluated by food frequency questionnaire. Participants followed lipid lowering diet for 12 weeks. Energy intake of omega-6 and omega-3 FA was changed from 7.6% and 0.6% to 5.7% and 1.2%, respectively. Marked decrease in four FA ratios in serum phospholipids, i.e., omega-6/omega-3, arachidonic acid (AA)/eicosapentaenoic acid (EPA), AA/docosahexaenoic acid (DHA), AA/(EPA+DHA) and omega-3 index (EPA+DHA) was found in study subjects after lipid-lowering diet. Total cholesterol/high-density lipoprotein (HDL), low-density lipoprotein (LDL)/HDL and triacylglycerol/HDL-cholesterol ratios positively correlated with all FA ratios, and negatively correlated with total omega-3 levels in serum phospholipids and omega-3 index in erythrocytes. Total serum omega-3 levels showed strongest association with lipoprotein ratios and positive correlation with homeostatic model assessment (HOMA) index. In conclusion, lipid-lowering diet resulted in decreased serum key FA ratios, increased omega-3 levels, and improved insulin sensitivity that may lead to a lower risk of cardiovascular disease in subjects with moderate hyperlipidemia.

RESUMO

The aim of this study was to compare dietary intake and status of polyunsaturated fatty acids (PUFA) in plasma and erythrocyte phospholipids metabolically healthy and unhealthy, and obese and nonobese persons. Metabolic health status in 171 participants was defined according to criteria for metabolic syndrome. Obese and nonobese metabolically unhealthy persons (MUHO and MUHNO) had higher energy intake of n-6 PUFA (7.82 ± 1.03 and 7.49 ± 0.86) and lower intake of n-3 PUFA (0.60 ± 0.12 and 0.62 ± 0.11) compared to obese and nonobese metabolically healthy persons (MHO and MHNO) (5.92 ± 0.63 and 5.72 ± 0.67; 1.20 ± 0.07 and 1.22 ± 0.09, respectively) and a higher n-6/n-3 PUFA ratio. The plasma level of n-6 PUFA was lower in the MUHO and MUHNO groups (38.49 ± 3.71 and 38.53 ± 2.19) compared to MHNO (40.90 ± 2.43), while n-3 PUFA status was lower in obese than in nonobese persons (3.58 ± 0.79 and 3.50 ± 1.02 vs. 4.21 ± 0.80 and 4.06 ± 1.15). The MHO group had a higher eicosapentaenoic/arachidonic acid ratio and estimated desaturase (SCD16, D6D) and elongase activity in plasma phospholipids compared to MHNO. The low intake of n-3 PUFA is directly associated with metabolic risk factors. These results indicated that obesity is closely associated with low levels of n-3 PUFA in plasma phospholipids, suggesting that dietary modifications including n-3 PUFA supplementation appear to be suitable therapeutic strategy in obese persons.

RESUMO

Autism Spectrum Disorder (ASD) is a complex neurodevelopmental disorder characterized by persistent deficits in social communication and social interaction across multiple contexts and restricted, repetitive patterns of behavior, interests and activities. The maternal status of polyunsaturated fatty acids (PUFA) regulates microglial activity and neuroinflammatory pathways during a child's brain development. In children with ASD, the metabolism of PUFA is thought to be deficient or abnormal, leading to increased production of proinflammatory cytokines, increased oxidative stress and an imbalance in the formation and action of neurotransmitters. In addition, nutritional deficits in omega-3 PUFA may affect gut microbiota and contribute to ASD by the gut-brain axis. The aim of this study was to review the possible role of neuroinflammation in ASD development and the effect of omega-3 PUFA supplementation in children with ASD. Due to a wide heterogeneity across RCTs, no definitive conclusion about omega-3 PUFA effects in ASD can be drawn. Supplementation with PUFA could be considered as one of the aspects in regulating the biological status of the organism and could provide added value to standard medical and psychological interventions for reducing behavioral deficits.

RESUMO

Our study aimed to examine the status of plasma fatty acids (FAs), inflammatory markers, and lipid peroxidation in patients with femoral neck fractures. The study included 20 patients (64-86 years) with femoral neck fractures indicated for surgery and a control group of 17 elderly subjects without fractures or serious chronic diseases. Plasma was obtained during the first 12 h postfracture and presurgery and 7 days postop. Compared to the control, patients had significantly higher saturated FA (SFA) and monounsaturated FA as well as increased TNF-α and IL-6. Opposite to that, levels of individual and total n-6 polyunsaturated FA (PUFA), individual and total n-3 PUFA, n-6/n-3 ratio, and levels of thiobarbituric acid reactive substances (TBARS) were markedly lower in the patient than in the controls. On the seventh day after the surgery, we showed a further rise in the SFA, oleic acid, and TNF-α and reductions of n-6 PUFA and IL-6. Taken together, our results suggest that altered FA status, especially reduced PUFA, may influence hip fracture repair and even contribute to femoral fracture susceptibility in the elderly. A potential benefit from nutritional intervention with PUFA in prevention and (or) fracture healing should be considered.

RESUMO

This study investigated different dietary strategies, high-fat (HFd), or standard diet (Sd) alone or in combination with standardized Aronia melanocarpa extract (SAE), as a polyphenol-rich diet, and their effects on lipids and fatty acids (FA) in rats with metabolic syndrome (MetS). Wistar albino rats were randomly divided into two groups: healthy and rats with MetS, and then depending on dietary patterns on six groups: healthy rats fed with Sd, healthy rats fed with Sd and SAE, rats with MetS fed with HFd, rats with MetS fed with HFd and SAE, rats with MetS fed with Sd, and rats with MetS fed with Sd and SAE. 4 weeks later, after an overnight fast (12-14 h), blood for determination of total cholesterol (TC), triglycerides (TG), high-density lipoprotein (HDL), low-density lipoprotein (LDL), index of lipid peroxidation (measured as TBARS), and FA was collected. Increased FA and lipid concentration found in MetS rats were reduced when changing dietary habits from HFd to Sd with or without SAE consumption. Consumption of SAE slightly affects the FA profiles, mostly palmitoleic acid in healthy rats and PUFA in MetS + HFd rats. Nevertheless, in a high-fat diet, SAE supplementation significantly decreases n-6/n-3 ratio, thereby decreasing systemic inflammation. Further researches are warranted to confirm these effects in humans.

RESUMO

OBJECTIVES: The aim of our study was to investigate whether N-acetyl-L-cysteine (NAC) could protect stem cells from exfoliated deciduous teeth (SHED) against oxidative damage, during in vitro cultivation, to preserve regenerative potential of these cells. Accordingly, we examined the potential of cell culture supplementation with NAC in prevention of lipid peroxidation, unfavorable changes of total lipids fatty acid composition, and the effects on the activity of antioxidant enzymes. MATERIAL AND METHODS: We analyzed the extent of oxidative damage in SHED after 48 h treatment with different NAC concentrations. Cellular lipid peroxidation was determined upon reaction with thiobarbituric acid. All enzyme activities were measured spectrophotometrically, based on published methods. Fatty acid methyl esters were analyzed by gas-liquid chromatography. RESULTS: Concentration of 0.1 mM NAC showed the most profound effects on SHED, significantly decreasing levels of lipid peroxidation in comparison to control. This dose also diminished the activities of antioxidant enzymes. Furthermore, NAC treatment significantly changed fatty acid composition of cells, reducing levels of oleic acid and monounsaturated fatty acids and increasing linoleic acid, n-6, and total polyunsaturated fatty acid (PUFA) proportions. CONCLUSION: Low dose of NAC significantly decreased lipid peroxidation and altered fatty acid composition towards increasing PUFA. The reduced oxidative damage of cellular lipids could be strongly related to improved SHED survival in vitro. CLINICAL RELEVANCE: Low doses of antioxidants, applied during stem cells culturing and maintenance, could improve cellular characteristics in vitro. This is prerequisite for successful use of stem cells in various clinical applications.

RESUMO

The aim of our study was to examine the effects of different dietary strategies, high-fat (HFd) or standard diet (Sd) alone or in combination with standardized oral supplementation (0.45 mL/kg/day) of Aronia melanocarpa extract (SAE) in rats with metabolic syndrome (MetS). SAE is an official product of pharmaceutical company Pharmanova (Belgrade, Serbia); however, the procedure for extraction was done by EU-Chem company (Belgrade, Serbia). Rats were divided randomly into six groups: control with Sd, control with Sd and SAE, MetS with HFd, MetS with HFd and SAE, MetS with Sd and MetS with Sd and SAE during 4 weeks. At the end of the 4-week protocol, cardiac function and liver morphology were assessed, while in the blood samples glucose, insulin, iron levels and systemic redox state were determined. Our results demonstrated that SAE had the ability to lower blood pressure and exert benefits on in vivo and ex vivo heart function. Moreover, SAE improved glucose tolerance, attenuated pathological liver alterations and oxidative stress present in MetS. Obtained beneficial effects of SAE were more prominent in combination with changing dietary habits. Promising potential of SAE supplementation alone or in combination with different dietary protocols in triggering cardioprotection should be further examined in future.

RESUMO

The effect of polyphenol-rich chokeberry juice consumption on plasma phospholipid fatty acid profiles of 32 active male and female handball players was examined. This randomized, double-blind, placebo-controlled study was conducted during the preparatory training in a closed campus, where 18 players (8 males, 10 females) consumed 100 mL of chokeberry juice, while 14 players (7 males, 7 females) consumed placebo. Lipid status, glucose, thiobarbituric acid reactive substances (TBARS), and percentages of fatty acids were assessed at baseline and at the end of the study. Consumption of chokeberry juice induced decreases of C18:1n-9 and C18:3n-3 in men, but no changes in female players. However, placebo-controlled groups had reduced proportions of mono- (C16:1n-7, C18:1n-7) and polyunsaturated fatty acids (PUFAs: C18:3n-3, C20:5n-3, and C22:4n-6) in males, as well as n-6 PUFAs and total PUFAs in females after consumption. These results indicate that chokeberry juice had a weak impact on attenuating the effect of intensive training in active handball players.

RESUMO

BACKGROUND: Childhood obesity, dental caries, and periodontal disease are major public health problems due to their adverse impact on the growth and development of children. AIM: To examine the association between nutritional status, oral health, and lifestyle habits among schoolchildren in Serbia. DESIGN: This cross-sectional study assessed 422 children and adolescents aged 6-18 years with the following dental indexes analyzed: DMF/dmf (decayed, missed, and filled teeth), plaque index (PI), and gingival index (GI). Depending on their nutritional status, the subjects were categorized, as being 'normal weight,' 'at risk of overweight,' and 'overweight.' Logistic regression was applied to study the association between the dental indexes and independent variables: gender, age, toothbrushing, nutritional status, and lifestyle factors. RESULTS: Being overweight positively correlated with GI, but negatively correlated with the DMF/dmf index among the participants. Multivariate analysis showed a strong association between the weight category and toothbrushing with GI and PI. Overweight children (6-11 years) were less likely to have caries, whereas in older children/adolescents (12-18 years), caries was associated with the intake of sugar-sweetened juices. CONCLUSIONS: Being overweight was found to be significantly associated with a higher probability of developing gingivitis and negatively associated with caries prevalence in Serbian children and adolescents.

RESUMO

The objectives were to examine if there is a causal relationship between osteosarcopenic adiposity (OSA) syndrome (coexistence of osteopenia/osteoporosis, sarcopenia, and excess adiposity) and cardiometabolic disorders or if these disorders initiate the development of OSA and its worsening. The search was conducted in PubMed, Scopus, and Web of Science to include articles up to the end of 2023. Of n=539 articles retrieved, n=15 met the eligibility criteria. Only studies conducted in adults and with all three body composition compartments (bone, muscle/lean, adipose) measured were considered. The results revealed that several cardiometabolic disorders, namely, hypertension, dyslipidemia (elevated total and LDL-cholesterol, lower HDL-cholesterol), insulin resistance, hyperglycemia, lower serum vitamin D, and some inflammatory markers were accompanied by OSA. In most cases, the OSA phenotype was associated with worse outcomes than cases with healthy or less impaired body composition. Our initial questions about the reciprocal cause-and-effect relationships could be surmised with more certainty for the OSA and some cardiovascular risks (hypertension, dyslipidemia) and some metabolic abnormalities (several inflammatory markers). The results of this review underscore the importance of body composition in health and from a clinical perspective, all three body composition compartments should be measured by standardized technologies using regulated diagnostic criteria to identify OSA. Randomized trials and prospective studies in diverse groups of older and younger individuals are necessary to determine if the relationships between OSA and clinical endpoints are causal and reversible through intervention and to uncover the mechanisms.

RESUMO

Diets high in fat and sugar lead to metabolic syndrome (MetS) and related chronic diseases. We investigated the effects of commercially available, cold-pressed polyphenol-rich black currant (BC) and cornelian cherry (CC) juices on the prevention of MetS in Wistar rats induced by a 10-weeks high-fat high-fructose (HFF) diet. Juice consumption, either BC or CC, with a HFF diet resulted in lower serum triglycerides compared to only the HFF consumption. Both juices also mitigated the effects of HFF on the liver, pancreas, and adipose tissue, by preserving liver and pancreas histomorphology and reducing visceral fat and adipocyte size. Furthermore, supplementation with both juices reduced glucagon and up-regulated insulin expression in the pancreas of the rats on the HFF diet, whereas the BC also showed improved glucose regulation. BC juice also reduced the expression of IL-6 and hepatic inflammation compared to the group only on HFF diet. Both juices, especially BC, could be a convenient solution for the prevention of MetS in humans.

RESUMO

Currently, a factorial approach is used to derive reference values for iron. Calculations include the use of a bioavailability factor to convert the physiological requirement, derived from obligatory losses and requirements for growth and development, into a dietary intake value. A series of systematic reviews undertaken by the EURRECA Network of Excellence aimed to identify data that may increase the accuracy of factorial calculations across all population groups. The selection of robust data was guided by the use of standardized review methodology and the evidence-based selection of status biomarkers and dietary intake assessment techniques. Results corroborated the dearth of relevant factorial data, including whole-diet bioavailability data, and confirmed the need to continue extrapolating physiological requirements across population groups. Data were also unavailable that would allow reference values to be based on selected health outcomes associated with iron intake or status. Ideally, a series of observational and randomized controlled trial (RCT) studies need to be undertaken across all population groups and life stages to generate robust data for setting dietary reference values for iron. It will also be essential to include information on polymorphisms that potentially influence iron absorption and status in the derivation process.

RESUMO

Physical activity is accompanied by the changes in Insulin-like Growth Factor I (IGF-I)/IGF-Binding Protein 1 (IGFBP-1) axis. Inconsistent results concerning IGF-I and IGFBP-1 levels were reported. In this study we have raised some questions on the events that occur at the molecular level of the exercise-related IGFBP-1 changes. We have examined the fragmentation pattern of IGFBP-1, IGFBP-1 protease activity, interaction between IGFBP-1 and alpha2-macroglobulin (α2M), and possible existence of minor structural changes of IGFBP-1 in professional soccer players. Athletes had significantly greater amounts of fragmented IGFBP-1, whereas no difference was found in the amount of intact IGFBP-1 compared with controls. An increased activity of matrix metalloprotease-9 (MMP-9) was detected in athletes, causing IGFBP-1 degradation down to the fragment of 9 kDa as the major one. The amount of α2M, which protects IGFBP-1 from proteolysis, or the amount of IGFBP-1/α2M complexes was unaltered. Finally, we have examined whether IGFBP-1 isolated from soccer players exhibited altered reactivity with several chemical surfaces used in surface-enhanced laser desorption/ionization-time of flight mass spectrometry (SELDI-TOF MS). Different reactivity was detected with anion and cation exchangers, suggesting existence of at least one sequence within IGFBP-1, whose ionization pattern was not equal in athletes and controls. Differences in spectra obtained with ion exchanges may reflect differences in IGFBP-1 phosphorylation. Physiological implications of the events described in this study on the IGF-I availability are, at this time, unknown. It can be hypothesized that IGFBP-1 proteolysis leads to altered distribution of IGF-I among IGFBPs, which may affect the final IGF-associated response.

RESUMO

The fatty acid composition of serum phospholipids were analyzed in 20 patients with alcoholic liver cirrhosis (11 with malnutrition and 9 with acceptable nutritional status); 25 healthy age and sex-matched adults were used as controls. Cirrhotic patients showed higher levels of palmitic acid and total saturated fatty acids than healthy subjects. Total n-6 and n-3 polyunsaturated fatty acids (PUFA), and levels of linoleic, dihomo-gama linolenic, arachidonic, and docosahexaenoic acid were significantly lower (p<0.001) in patients with alcoholic cirrhosis compared to healthy controls. Significant changes were also found between patients stratified according to nutritional status. In particular, the sum of n-3 PUFA was significantly lower (p<0.001) and ratio of n-6/n-3 fatty acids was higher (p<0.01) in malnourished patients when compared to the patients with acceptable nutritional status. Furthermore, important changes in the levels of saturated fatty acids, palmitoleic and oleic acid and long-chain PUFA were found in well-nourished patients with alcoholic cirrhosis as well. Our present data confirmed evidence that malnutrition is one of the factors that led to lower levels of polyunsaturated fatty acids in patients with alcoholic liver cirrhosis. PUFA supplementation in the latter needs further investigation.

RESUMO

Breast cancer is the most common malignant tumor and one of the leading causes of cancer-related death in women throughout the world. This study is a parallel, randomized, double-blind, controlled, 12-week supplementation trial, investigating the anti-inflammatory effects of dietary intake of fish oil and evening primrose oil (EPO), in patients with breast cancer undergoing chemotherapy. The primary outcomes were changes in the nutritional status and inflammatory cytokines of patients during the study. The secondary outcomes were changes in hematological and biochemical parameters and fatty acid profile. Of the 32 eligible patients, half of them is randomly assigned to a treatment arm with fish oil and EPO (n = 16), or a control arm (n = 16) with mineral oil as a placebo. The intervention group was taking 2 gel capsules of fish oil and 3 gel capsules of EPO (400 mg eicosapentaenoic acid, 600 mg docosahexaenoic acid, and 351 mg gamma-linolenic acid) fish oil and evening primrose oil for 12 weeks, during their chemotherapy. The control/placebo group was taking 5 gel capsules of 1g of mineral oil. One of the patients dropped out due to discontinuation of the treatment (in the placebo group) and two did not show up at the post-treatment measurements (in the intervention group), thus, 29 women completed the study. The results showed an increase in plasma levels of docosapentaenoic acid (22:5n-3), docosahexaenoic acid (22:6n-3), total n-3PUFA, vaccenic acid (18:1n-7), and a decrease in n-6/n-3 PUFA ratio in the intervention group. An increase in the plasma level of dihomo-gamma-linolenic acid (20:3n-6) was observed in the placebo group. There was no difference in plasma levels of interleukin (IL) IL-8, IL-10, and tumor necrosis factor-alpha, while the level of IL-6 decreased in both groups and was significantly lower in the intervention group at the end of the study. In conclusion, this supplementation improved the PUFA status and decreased the level of IL-6 in breast cancer patients undergoing chemotherapy. Consequently, this treatment may help reduce cancer complications resulting from impaired lipid metabolism and inflammation. ClinicalTrials.gov Identifier: NCT03516253.

RESUMO

Herb-induced liver injury (HILI) caused by herbal supplements, natural products, and products used in traditional medicine are important for differential diagnoses in patients with acute liver injury without an obvious etiology. The root of Withania somnifera (L.) Dunal, commonly known as ashwagandha, has been used in Ayurvedic medicine for thousands of years to promote health and longevity. Due to various biological activities, ashwagandha and its extracts became widespread as herbal supplements on the global market. Although it is generally considered safe, there are several reported cases of ashwagandha-related liver injury, and one case ended with liver transplantation. In this paper, we review all reported cases so far. Additionally, we describe two new cases of ashwagandha hepatotoxicity. In the first case, a 36-year-old man used ashwagandha capsules (450 mg, three times daily) for 6 months before he developed nausea, pruritus, and dark-colored urine. In the second case, a 30-year-old woman developed pruritus after 45 days of using ashwagandha capsules (450 mg). In both cases, serum bilirubin and liver enzymes (aspartate transaminase (AST), alanine transaminase (ALT), and alkaline phosphatase (ALP) were increased. The liver injury pattern was hepatocellular (R-value 11.1) and mixed (R-value 2.6), respectively. The updated Roussel Uclaf Causality Assessment Method (RUCAM) (both cases with a score of seven) indicated a "probable" relationship with ashwagandha. Clinical and liver function improvements were observed after the discontinuation of ashwagandha supplement use. By increasing the data related to ashwagandha-induced liver injury, these reports support that consuming ashwagandha supplements is not without its safety concerns.

RESUMO

It is hypothesized that plasma proportion of selected fatty acids (FAs) and dietary habits are linked with the risk of cardiovascular disease (CVD) in postmenopausal women. Therefore, this study was designed to determine the association of plasma FA composition and markers of dietary habits with an atherogenic index of plasma (AIP), a predictor of CVD risk in postmenopausal women. In total, 87 postmenopausal women with an average age of 57 ± 7 years were recruited and their dietary intake, anthropometric and biochemical parameters, and FA status in total plasma lipid proportions were determined, showing that 65.5% of the participants had a high risk of CVD according to their AIP value. After adjusting for some confounders (age, body mass index, and physical activity level), the risk of CVD was only positively associated with the frequency of consumption of animal fat spreads (butter and lard) of terrestrial origin. Regarding the FA profile, CVD risk was positively associated with the percentages of vaccenic acid, dihomo-γ-linolenic acid, and monounsaturated fatty acids (MUFA; mainly n-7) in total FA, as well as the MUFA/SFA ratio in total plasma and stearoyl-CoA desaturase-16 activity (16:1/16:0 ratio). In contrast, the risk of CVD was negatively associated with percentages of α-linolenic acid, total polyunsaturated fatty acids (PUFA), and PUFA/MUFA ratio in total plasma lipid, and the estimated activity of Δ5-desaturase (20:4/20:3 n-6 ratio). These results support the current recommendations to decrease the frequency of animal fat spread intake because it is associated with a reduced CVD risk based on AIP in postmenopausal women. In accordance with these plasma percentages of ALA, vaccenic acid, dihomo-γ-linolenic acid, PUFA, PUFA/MUFA ratio, and 16:1/16:0 ratio may be important parameters in CVD risk assessment.
