A pilot longitudinal study of decrease in cognitive functions during the most painful day of the period among women with primary dysmenorrhea.

PURPOSE: Painful menstruation is a common problem associated with many limitations in day-to-day functioning. There is limited research on the temporary effects of menstrual pain on cognitive functioning. METHODS: A longitudinal pilot study was conducted. A group of 32 women was tested with the Brief Test of Adult Cognition by Telephone (BTACT), which consists of 7 tests measuring various cognitive functions. Participants were tested both on a regular, pain-free day and the most painful day of their period. RESULTS: The subjects displayed significantly lower results in several domains of cognitive functions during measurement on the most painful day of the period. We observed a decline in inhibitory and cognitive control, attention functioning and processing speed. CONCLUSIONS: The results provide tentative evidence for experiencing cognitive difficulties under the influence of menstrual pain and may contribute to raising awareness about related difficulties.

Factors associated with prolonged COVID-related PTSD-like symptoms among adults diagnosed with mild COVID-19 in Poland.

COVID-19 has been considered a possible cause of post-traumatic stress disorder (PTSD) or similar conditions. However, what specific disease symptoms may contribute most to prolonged PTSD-like symptoms in COVID-19 survivors is unclear. The study aimed to present the factor structure of COVID-19 symptoms and identify which symptoms of COVID-19 best explain the subsequent presence of PTSD-like symptoms in mild COVID-19 survivors. COVID-positive adults (n = 341) completed online self-report scales at the baseline assessment (T1) and after approximately 4 months (T2), including The Patient Health Questionnaire Anxiety-Depression Scale; The Scale of Psychosocial Experience Related to COVID-19, The Primary Care PTSD Screen for DSM-5; and self-designed questionnaires evaluating the severity of COVID-related medical and neurocognitive symptoms and pre-pandemic variables. Exploratory factor analysis revealed five factors of COVID-19 symptoms: flu-like, respiratory, cold, neurological, and neurocognitive. Hierarchical logistic regression showed that besides selected control variables (anxiety and depression, presence of PTSD-like symptoms, COVID-related stigma in T1), neurocognitive symptoms of COVID-19 in T1 but not other symptoms of the disease were a significant predictor of the presence of PTSD-like symptom in T2. Findings suggest a need for a comprehensive neurocognitive assessment of people diagnosed with COVID-19 and prompt interventions targeting the prevention of potential risks for long-term PTSD-like states at the community level.

Assessment of Neurocognitive Functions, Olfaction, Taste, Mental, and Psychosocial Health in COVID-19 in Adults: Recommendations for Harmonization of Research and Implications for Clinical Practice.

OBJECTIVE: To propose a set of internationally harmonized procedures and methods for assessing neurocognitive functions, smell, taste, mental, and psychosocial health, and other factors in adults formally diagnosed with COVID-19 (confirmed as SARS-CoV-2 + WHO definition). METHODS: We formed an international and cross-disciplinary NeuroCOVID Neuropsychology Taskforce in April 2020. Seven criteria were used to guide the selection of the recommendations' methods and procedures: (i) Relevance to all COVID-19 illness stages and longitudinal study design; (ii) Standard, cross-culturally valid or widely available instruments; (iii) Coverage of both direct and indirect causes of COVID-19-associated neurological and psychiatric symptoms; (iv) Control of factors specifically pertinent to COVID-19 that may affect neuropsychological performance; (v) Flexibility of administration (telehealth, computerized, remote/online, face to face); (vi) Harmonization for facilitating international research; (vii) Ease of translation to clinical practice. RESULTS: The three proposed levels of harmonization include a screening strategy with telehealth option, a medium-size computerized assessment with an online/remote option, and a comprehensive evaluation with flexible administration. The context in which each harmonization level might be used is described. Issues of assessment timelines, guidance for home/remote assessment to support data fidelity and telehealth considerations, cross-cultural adequacy, norms, and impairment definitions are also described. CONCLUSIONS: The proposed recommendations provide rationale and methodological guidance for neuropsychological research studies and clinical assessment in adults with COVID-19. We expect that the use of the recommendations will facilitate data harmonization and global research. Research implementing the recommendations will be crucial to determine their acceptability, usability, and validity.

Neuropsychological disorders after COVID-19. Urgent need for research and clinical practice.

Purpose: Numerous studies suggest that infection with coronavirus SARS-CoV-2, which causes acute respiratory distress syndrome and COVID-19 illness, can lead to changes in the central nervous system (CNS). Consequently, some individuals with SARS-CoV-2 infection may also present the symptoms of neuropsychological disorders. The goals of this literature review is the synthesis of various perspectives and up-to-date scientific knowledge as well as the formulation of initial recommendations for clinical practice. Views: According to current state of knowledge, numerous SARS-CoV-2 infection-specific and nonspecific risk factors exist for brain damage, which might lead to neuropsychological impairments in individuals who have recovered from COVID-19. The emerging evidence suggests significant behavioral and cognitive deficits in COVID-19 survivors, which are present in the early phase after recovery and persist for several months. Neuropsychological disturbances can potentially include a wide spectrum of disorders, yet deficits of attention, memory, executive functions, language and visuospatial orientation are among most commonly identified. The relationship between cognitive impairment, emotional disturbances and severity of COVID-19 symptoms needs to be submitted to further research. Conclusions: The scientific knowledge resulting from neuropsychological empirical studies during the COVID-19 pandemic allows for a postulate of an urgent evidence-based systematic neuropsychological research to be conducted among COVID-19 survivors. More than anything, the recovered individuals must be provided with adequate neuropsychological help in the form of neuropsychological diagnosis, monitoring and rehabilitation.

The use of 67Ga scintigraphy in patients with sarcoidosis.

Sarcoidosis is a systemic disease of unknown aetiology characterised by the formation of noncaseating granulomas in various organs and tissues. The various imaging modalities that are useful in the investigation of lesions, staging and establishing indications for treatment include: conventional radiography, CT, MRI, and scintigraphy with 67Ga, ²°¹Tl, 99mTc sestamibi, and somatostatin receptor scintigraphy (SRS) as well as ¹8F-FDG-PET/CT. This paper discusses the most commonly used technique of the scintigraphic, gallium (67Ga) citrate) and its role in the evaluation and monitoring of patients with sarcoidosis.

Can Youthful Mesenchymal Stem Cells from Wharton's Jelly Bring a Breath of Fresh Air for COPD?

Chronic obstructive pulmonary disease (COPD) is a major global cause of morbidity and mortality, projected to become the 3rd cause of disease mortality worldwide by 2020. COPD is characterized by persistent and not fully reversible airflow limitation that is usually progressive and is associated with an abnormal chronic inflammatory response of the lung to noxious agents including cigarette smoke. Currently available therapeutic strategies aim to ease COPD symptoms but cannot prevent its progress or regenerate physiological lung structure or function. The urgently needed new approaches for the treatment of COPD include stem cell therapies among which transplantation of mesenchymal stem cells derived from Wharton's jelly (WJ-MSCs) emerges as a promising therapeutic strategy because of the unique properties of these cells. The present review discusses the main biological properties of WJ-MSCs pertinent to their potential application for the treatment of COPD in the context of COPD pathomechanisms with emphasis on chronic immune inflammatory processes that play key roles in the development and progression of COPD.

Comparative Efficacy of Topical Pertmehrin, Crotamiton and Sulfur Ointment in Treatment of Scabies.

BACKGROUND: Scabies is an ectoparasitic infection, which occurs because of direct skin-to skin contact. The ideal treatment modality is still unclear and further research on this topic is warranted. The aim of the study was to compare the efficacy and safety of the topical scabicides: permethrin, crotamiton and sulfur ointment. METHODS: Fifty four patients with diagnosed scabies were randomly divided into three treatment groups. The first group received 5% permethrin cream twice with one week interval, the patients from the second group were given crotamiton lotion for two days twice with one week interval, while the third group received 10% sulfur ointment for two or three weeks. All patients were followed up at 1, 2 and 4 weeks intervals. RESULTS: At one-week follow up the cure rate was significantly higher at permethrin-treated group when compared to crotamiton group (P< 0.001) and sulfur group (P< 0.001). At the end of two-week interval, the cure rate at permethrin group was 100%, while at crotamiton group, 66.7% and in sulfur group 38.9% (P< 0.001). At 4-week follow up the applied treatment was effective in all studied individuals. CONCLUSION: The topical application of permethrin, crotamiton and sulfur was equally efficacious at 4-week follow up, however permethrin cream showed faster improvement at first and second follow up. Acquiring permethrin is considered as expensive option and crotamiton lotion seems to be cost-less alternative to this cream.

[Pulse wave velocity as an early marker of diastolic heart failure in patients with hypertension]. / Predkosc fali tetna jako wczesny marker rozkurczowej niewydolnosci serca u chorych na nadcisnienie tetnicze.

According to the WHO, hypertension is one of the major causes of death worldwide. It leads to a number of severe complications. Diastolic heart failure, that is heart failure with preserved ejection fraction (HFPEF), is especially common. New, but simple, indices for the early detection of patients who have not yet developed complications or are in their early developmental stages are still searched for. AIM: The aim of this study is to examine the correlation between pulse wave velocity (PWV) and markers of diastolic heart failure (DHF) assessed in echocardiography in patients with hypertension and no symptoms of heart failure. MATERIALS AND METHODS: The study was comprised of 65 patients with treated hypertension. Patients with symptoms of heart failure, those with diabetes and smokers were excluded. Arterial stiffness was measured with the Mobil-O-Graph NG PWA. Pulse wave velocity (PWV) was estimated. The following markers of diastolic heart failure were assessed in the echocardiographic examination: E/A ratio - the ratio of the early (E) to late (A) ventricular filling velocities, DT - decceleration time, E/E' - the ratio of mitral peak velocity of early filling (E) to early diastolic mitral annular velocity E' in tissue Doppler echocardiography. RESULTS: PWV was statistically significantly higher in the DHF group. In the group of patients with heart failure, the average E/A ratio was significantly lower as compared to the group with no heart failure. CONCLUSIONS: Oscillometric measurement of pulse wave velocity is non-invasive, lasts a few minutes and does not require the presence of a specialist. It allows for an early detection of patients at risk of diastolic heart failure even within the conditions of primary health care.

Foreign Body in the Airway a Female Patient with Myasthenia Gravis.

Aspiration of a foreign body occurs rarer in adults than it does in children. Advanced age and swallowing disorders, often caused by neuromuscular diseases, predispose for aspiration. Symptoms due to aspiration are mainly cough and wheezing. However, clinical and radiological symptoms may mistakenly suggest lung cancer. Making a proper diagnosis could be difficult and time consuming. In this study we report a case of a 73-year old woman who has been diagnosed and treated myasthenia gravis for 10 years. The patient manifested chronic cough for over a year, weight loss, lung lesions on chest X-ray and computed tomography images in the form of atelectasis and inflammatory infiltrations. The results of cytological tests of bronchoalveolar lavage fluid were 'atypical cells' which suggested a lung cancer. Flexible bronchoscopy set the diagnosis as a foreign body in right upper bronchus, which turned out to be a piece of a plant obstructing the bronchus. The patient came down with pneumonia. Laboratory examinations revealed leucocytosis and a high level of C-reactive protein. A complete removal of foreign body took place during rigid bronchoscopy. Concomitantly, but unrelated to the finding of a foreign body in the bronchus, the patient was diagnosed with digestive tract perforation on the basis of X-ray images, which remained otherwise asymptomatic. Explorative laparotomy revealed a perforated colonic diverticulum, which was successfully treated surgically.

Lysosomal enzymes in serum and synovial fluid in patients with osteoarthritis.

OBJECTIVE: To assess the activity of arylsulfatase (AS), acid phosphatase (ACP), cathepsin D (CAT-D) and alpha-1 antitrypsin (AAT) in blood serum and synovial fluid (SF) of patients with hip or knee osteoarthritis (OA). METHODS: The study included 43 subjects with OA (35 hip OA, 8 knee OA), submitted total joint replacement. The control group consisted of 58 subjects with no past history of musculoskeletal disorders. RESULTS: The OA blood serum samples showed a significantly higher level of lysosomal enzymes activity than in the control group (AS by 17.8%, AAT by 42.4%); only the CAT-D activity decreased by 50%). AS, ACP and CAT-D activities were about two-fold higher in SF when compared with blood of OA patients. The differences between the genders were visible in the SF: Total protein concentration, activity of ACP (both higher in OA men) and activity of CAT-D (higher in OA women). Between the involved hip and knee, there were no significant differences in all estimated parameters in the blood serum of the OA group. In regard to the SF, only ACP activity was significantly higher in patients with a hip involved. CONCLUSIONS: The osteoarthritic SF enzymatic profile differs from that in normal joints. The OA in joints is not reflected in the systemic response. Our preliminary results suggest further studies on role of lysosomal enzymes (ACP and AS) as biomarkers for the detection of osteoarthritis.

Relationship between serum transforming growth factor ß 1 concentrations and the duration of type 1 diabetes mellitus in children and adolescents.

The aim of this study was to evaluate the relationship between serum transforming growth factor ß 1 (TGF- ß 1) concentrations and the duration of type 1 diabetes mellitus (T1DM) in children and adolescents. One hundred and sixteen patients with T1DM and 19 healthy controls were examined. Serum TGF- ß 1 concentrations were measured using the cytometric bead array (CBA). A positive association between the time of diabetes duration and higher serum TGF- ß 1 concentrations was observed. Similarly, the prevalence of microvascular complications, such as retinopathy and nephropathy, increased with the duration of diabetes. Logistic regression analysis showed that serum TGF- ß 1 concentrations and the duration of the disease are independent risk factors of microangiopathy development. Higher serum TGF- ß 1 concentrations were associated with a significant risk of microangiopathy development after 10 years of T1DM duration. In the successive years of the disease, the effect was even stronger. The results of our study indicate that serum TGF- ß 1 concentrations are one of the factors that may have an impact on the progression of vascular complications in children and adolescents with T1DM.

Serum concentrations of transforming growth factor-Beta 1 in predicting the occurrence of diabetic retinopathy in juvenile patients with type 1 diabetes mellitus.

In the present study, we have decided to evaluate if serum transforming growth factor-beta 1 (TGF- ß 1) concentrations may have diagnostic value in predicting the occurrence of diabetic retinopathy (DR) in juvenile patients with type 1 diabetes mellitus (T1DM). The study included 81 children and adolescents with T1DM and 19 control subjects. All study participants had biochemical parameters examined, underwent an eye examination, and 24-hour blood pressure monitoring. Moreover, serum concentrations of TGF- ß 1 were measured. The group of patients with T1DM and nonproliferative diabetic retinopathy (NPDR) had statistically significant higher serum levels of TGF- ß 1 (P = 0.001) as compared to T1DM patients without retinopathy as well as the healthy control subject. The threshold serum TGF- ß 1 concentrations which had a discriminative ability to predict the presence of DR were calculated using the receiver operating characteristic (ROC) curves analysis and amounted to 443 pg/ml. The area under the ROC curve (AUCROC) was 0.80, and its population value was in the range of 0.66 to 0.94. The sensitivity and specificity were calculated to be 72% and 88%, respectively. Our results suggest that TGF- ß 1 serum concentrations may be an additional parameter in predicting the occurrence of DR in juvenile patients with T1DM.

Effects of open versus laparoscopic nephrectomy techniques on oxidative stress markers in patients with renal cell carcinoma.

The aim of the study was to determine the concentration of lipid peroxidation products, the activity of selected antioxidant and lysosomal enzymes, and protease inhibitor in patients with renal cell carcinoma who underwent radical nephrectomy. The studied group included 44 patients: 21 of them underwent open surgery, while 23 underwent laparoscopy. Blood samples were collected three times: before treatment and 12 hours and five days after nephrectomy. In blood of participants, the concentration of thiobarbituric acid reactive substances (TBARS), the activity of catalase (CAT), superoxide dismutase (SOD) and glutathione peroxidase (GPx), and the activity of acid phosphatase (AcP), arylsulfatase (ASA), cathepsin D (CTSD), and α 1-antitrypsin (AAT) were assayed. No statistically significant differences in investigated parameters were found between studied groups. Moreover, TBARS concentration and CAT, SOD, and GPx activity were not altered in the course of both types of surgery. Five days after both open and laparoscopic nephrectomy techniques, AAT activity was higher than its activity 12 hours after the procedure. The obtained results suggest that laparoscopy may be used for nephrectomy as effectively as open surgery without creating greater oxidative stress. Reduced period of convalescence at patients treated with laparoscopy may be due to less severe response of acute-phase proteins.

Threshold serum concentrations of tumour necrosis factor alpha (TNFα) as a potential marker of the presence of microangiopathy in children and adolescents with type 1 diabetes mellitus (T1DM).

The aim of this study was to estimate the threshold serum concentrations of advanced glycation end products (AGEs) and their soluble receptors (sRAGE) as well as tumour necrosis factor alpha (TNFα), vascular endothelial growth factor(165) (VEGF(165)) and interleukin-12 (IL-12) in predicting the occurrence of microangiopathy in children and adolescents with type 1 diabetes mellitus (T1DM). We studied 88 children and adolescents (age range: 6-20 yrs) with T1DM and 32 control subjects (age range: 7-20 yrs). All study participants had their daily urinary albumin excretion, HbA1c and serum creatinine levels measured, and underwent an eye examination and 24-h blood pressure monitoring. Moreover, serum concentrations of AGEs, sRAGE, TNFα, VEGF(165) and IL-12 were measured. In order to calculate the threshold values of the studied parameters, the Receiver Operating Characteristic (ROC) curve analysis was used. The results of our study have shown that among all the studied parameters a discriminative ability was found for TNFα, VEGF(165), duration of the disease, serum AGEs concentrations and daily urinary albumin excretion. However, the highest value of the area under the ROC curve (AUC(ROC)) in predicting the occurrence of diabetic microangiopathy was found for serum TNFα concentrations with its threshold value of 1.7 pg/ml [AUC(ROC) = 0.88 (95% CI: 0.79-0.97)]. The sensitivity and specificity for this variable was at the level of 85.7% and 94.3%, respectively. In conclusion, according to our results serum TNFα concentrations over 1.7 pg/ml may point to the presence of diabetic microangiopathy in children and adolescents T1DM.

The association of the IVS1-397T>C estrogen receptor α polymorphism with the regulatory conditions in longstanding type 1 diabetic girls.

Type 1 diabetes is considered as pluricausal disease, whose etiology involves genetic predisposition as well as environmental factors that contribute to disease progression and pathogenesis. Women are believed to be more susceptible to develop autoimmune diseases, which may depend in part on the influence of sex hormones on the immune system. It was shown that estrogens may protect against the development of autoimmune disease by inducing the expansion of regulatory T cell pool and upregulating Foxp3 expression. Foxp3 is a transcription factor that controls the development and suppressive function of naturally occurring regulatory T cells CD4(+)Foxp3(+). Longstanding diabetes type 1 has features of low-grade chronic inflammation which may influence regulatory T cell subset by reducing their numbers or/and inhibiting their suppressive potential. As diabetic type 1 patients are differentiated with regard to metabolic factors, level of glycemic control and systemic inflammatory state, we aimed to examine if this can be associated with IVSI-397T>C estrogen receptor α polymorphism. We examined 93 young regularly menstruating girls with diagnosed type 1 diabetes and 49 healthy age-matched control individuals. The PvuII polymorphism of the ER-α gene was analyzed as well as the serum TNF level and the level of CD4(+)Foxp3(+) regulatory T cells in these individuals. Girls with type 1 diabetes had lower level of CD4(+)Foxp3(+) Tregs than their healthy counterparts. Regulatory T cells from these patients showed also lower expression of Foxp3 than Tregs in healthy, control group. In addition, DM1 girls bearing the CC genotypes showed the highest level of CD4(+)Foxp3(+) Tregs and the lowest TNF serum level in comparison to girls carrying CT or TT genotype. The CC DM1 carriers had also higher serum level of estrogens than girls bearing CT or TT genotype. We propose that different variants of IVS1-397 estrogen receptor α polymorphism may become additional genetic factor that influences regulatory conditions during diabetes type 1 in females.

The -174GG interleukin-6 genotype is protective from retinopathy and nephropathy in juvenile onset type 1 diabetes mellitus.

The aim of our study was to determine an association between the -174G>C IL-6 polymorphism (rs1800795) and occurrence of retinopathy and nephropathy in type 1 diabetes mellitus (T1DM) patients. Two hundred ten children/adolescents with long-standing T1DM (16.5 +/- 3.8 y; with diabetes duration of 8.4 +/- 3.0 y) were enrolled into the study. A group of 170 healthy young (16.9 +/- 5.2 y) sex-matched volunteers was qualified as the control. The IL-6 polymorphism was genotyped with the PCR-RFLP method. Serum and urine IL-6 concentrations were measured by the ultra-sensitive ELISA tests. The -174GG genotype was under represented in the diabetic patients compared with the controls. Patients with this genotype were free from nephropathy and retinopathy. The group of -174GG carriers was characterized by the highest urine IL-6 concentrations in relation to other genotypes. In the multivariate logistic regression analysis adjusted for age, duration of the disease, age of disease onset, HbA1c, and albumin excretion rate, the -174GG genotype was the only independent variable that significantly decreased the risk of jointly analyzed retinopathy and nephropathy [OR = 0.65; 95% CI = 0.52-0.82; p = 0.0003]. We propose that the -174GG patients are protected from late diabetic complications by different IL-6 dependent mechanisms.

Interleukin 6 -174(G>C) gene polymorphism is related to celiac disease and autoimmune thyroiditis coincidence in diabetes type 1 children.

The aim of the study was to assess the relationship between IL-6 gene polymorphism at -174(G>C) and the coincidence of celiac and autoimmune thyroid diseases with type 1 diabetes mellitus (DM1) in children. 200 children with DM1 aged 13.23+/-3.54 years and 172 healthy controls were analyzed. The IL-6 gene -174(G>C) polymorphism at the promoter region of the gene was analyzed by the PCR-RFLP method. The genotype distribution was significantly different in diabetic children as compared to the healthy controls (p=0.01). In DM1 patients GC heterozygotes were the most common (52.5%), while CC homozygotes accuted for 29% and GG homozygotes only for 18% of cases. In contrast, GG homozygotes were much more frequent among healthy children (31%). Besides, the GG homozygotes were significantly more frequent among diabetic children with celiac disease (p=0.04) in relation to those without autoimmune complications. In children with autoimmune thyroiditis, the distribution of the IL-6 genotypes was similar to that seen in diabetic patients without autoimmune complications (p=0.24). The results of our study suggest that the diabetic children, who have IL-6 gene -174GG genotype may have an increased risk for celiac disease development.

[Investigation of the contents of essential elements in nuts, almonds and dry fruits]. / Badanie zawartosci niezbednych skladników mineralnych w orzechach, migdalach i suszonych owocach.

Concentrations of Ca, P, Fe, Zn, Cu and Mn were determined in nuts, almonds as well as in dry fruits available on Polish market. The contents of minerals in 100 g of nuts were as follows: 55.8-261 mg Ca; 294-724 mg P; 1.11-3.06 mg Fe; 2.05-4.98 mg Zn; 0.5-1.38 mg Cu and 0.93-5.75 mg Mn. Among the analysed dry fruits, the greatest concentrations of calcium, phosphorus, zinc and cooper were recorded for figs, while apricots contained the highest levels of iron and manganese. Based on the data obtained it was possible to estimate the realization of the recommended daily intake of essential elements with the 100 g portion of analysed products for an adult person.

Differentiation of market coffee and its infusions in view of their mineral composition.

The concentrations of 14 elements (Ca, Mg, K, Na, P, Co, Mn, Fe, Cr, Ni, Zn, Cu, Cd, Pb) were determined in market coffee samples after dry mineralisation of both dry samples and infusions evaporated to dryness. The total metal contents were analysed by flame atomic absorption spectrometry (F-AAS) using deuterium-background correction. Phosphorus was determined in the form of phosphomolybdate by spectrophotometric method. Reliability of the procedure was checked by the analysis of the certified reference materials Tea (NCS DC 73351), Cabbage (IAEA-359) and Spinach leaves (NIST-1570). It was concluded, based on RDA calculated for essential metals, that coffee infusions are not an important source of bioelements in human diet. In the case of toxic elements Provisional Tolerable Weekly Intake (PTWI) was estimated and there is no health hazard associated with exposure to Cd and Pb via coffee consumption. Significant correlation coefficients (p<0.001, p<0.01 and p<0.05) were found between concentrations of some metals in coffee. Factor analysis and canonical analysis were applied to the data processing in order to characterise the market coffee samples. The 12 metals determined were considered as chemical descriptors of each sample. Based on the mineral composition, it was possible to differentiate chemometrically particular types of coffee distinguishing arabica from robusta, ground from instant coffee, and their infusions.

[Concentration of several bioelements in bread and other plant supplements]. / Zawartosc wybranych biopierwiastków w pieczywie oraz roslinnych dodatkach do pieczywa.

Concentrations of Ca, P, Fe, Zn and Cu were determined in grain products such as bread and crispbread with natural supplements, and also in seeds and other cereal products available on Polish market, added to improve bread's quality and nutritional value. The contents of minerals in bread were as follow: 35.3-78.4 mg Ca; 88.4-364 mg P; 3.03-5.63 mg Fe; 1.96-3.15 mg Zn and 0.27-0.64 mg Cu in 100 g of product. Among the analyzed products, the highest level of calcium was recorded for poppy and sesame seeds. Based on the data obtained it was possible to estimate the realization of the recommended daily intake of bioelements with the analyzed products for an adult person.
