Abstract Background Routine cytomegalovirus (CMV) screening during pregnancy is not recommended in the United States and the extent to which it is performed is unknown. Using a medical claims database, we computed rates of CMV-specific testing among pregnant women. Methods We used medical claims from the 2009 Truven Health MarketScan® Commercial databases. We computed CMV-specific testing rates using CPT codes. Results We identified 77,773 pregnant women, of whom 1,668 (2%) had a claim for CMV-specific testing. CMV-specific testing was significantly associated with older age, Northeast or urban residence, and a diagnostic code for mononucleosis. We identified 44 women with a diagnostic code for mononucleosis, of whom 14% had CMV-specific testing. Conclusions Few pregnant women had CMV-specific testing, suggesting that screening for CMV infection during pregnancy is not commonly performed. In the absence of national surveillance for CMV infections during pregnancy, healthcare claims are a potential source for monitoring practices of CMV-specific testing.

Abstract Backround The aim of the present study was to assess the effects of zinc or copper and polyphenolic compounds on the 8-isoprostaglandin F2α concentration in the serum and urine of rats with mammary cancer (adenocarcinoma) induced with 7,12-dimethylbenz[a]antracene. The research focused on the kinetics of alterations in urinary 8-isoPGF2α at the early stage of carcinogenesis as well as the influence of dietary factors on the process. The impact of selected compounds on the intensity of DMBA - induced carcinogenesis was also assessed. Result and conclusions Administration of DMBA, a compound that inducers mammary tumors in experimental animals, increased the serum and urinary 8-isoPGF2α levels in study rats. In the rat model, diet supplementation with zinc, combined with selected polyphenolic compounds (resveratrol or genistein) yielded a statistically significant decrease in the rat serum and urinary biomarker concentration with a simultaneously significant stimulation of carcinogenesis. The results indicate that there is an inverse correlation between the intensity of DMBA-induced carcinogenicity and the level of 8-isoPGF2α in urine and serum of rats.

- Abstract
Due to the scale of the phenomenon, food allergy constitute a significant health problem and significantly impair the quality of life of patients. Differential diagnostics, including skin tests, sIgE detection tests, basophil and mast cell activation tests as well as double-blind placebo-controlled food challenge tests, is the gold standard in the diagnosis of food allergy. Recently, increasing attention has been paid to the potential use of nasal provocation test in the diagnosis of food allergy. Allergen dose, protocol standardization, assessment of subjective complaints and objectivization of test results are important factors determining the applicability of provocation tests., Competing Interests: The authors declare no conflict of interest., (Copyright: © 2023 Termedia Sp. z o. o.)

- Abstract
Thanks to their valuable assessment possibilities (subjective complaints and changes in nasal patency during the examination), nasal provocation tests may serve as an alternative tool for oral food challenges in the future. However, this test requires successive attempts to regulate its methodology in order to develop a standardized lyophilisate form and determine the threshold dose for a positive result. The study objective was to present the methodological foundation for nasal food allergen provocation tests induced by freeze-dried powdered chicken egg whites. A control group of 25 individuals with no history of allergy to chicken eggs or any other allergy was included in the study. Optical rhinometry and visual analog scales were used to assess the response of nasal mucosa to local allergen challenges. Minor variations in nasal flows, as measured by optical rhinometry, were observed in the provocation tests. The mean optical density measurements (as measured regardless of the allergen dose used) varied from positive to negative values and vice versa, e.g., amounting to 0.018 OD (standard deviation 0.095) at 15 min and -0.011 OD (standard deviation 0.090) at 30 min. No significant differences were observed concerning the perceived nasal discomfort using the visual analog scale. Due to the absence of nasal mucosal reactivity, nasal challenge is an excellent methodological tool for implementing food allergen tests.

- Abstract
Introduction: The nasal allergen provocation test plays an important role in differential diagnostics of rhinitis. Due to its informative potential, the test is also becoming increasingly used in other areas of diagnostics, including the diagnostics of food allergies., Aim: To assess the reactivity of nasal mucosa to the cow's milk protein allergens (as being widely used in powdered form in the food industry)., Material and Methods: The study material consisted of a group of 31 healthy subjects not sensitized to environmental allergens including cow's milk protein allergens. The study method involved an incremental nasal provocation test with cow's milk protein evaluated using the visual analog scale and acoustic rhinometry., Results: A total of 29 out of 31 volunteers presented with a significant decrease in nasal patency (control solution: 1.112 ±0.161 vs. local allergen application 1.005 ±0.157; p < 0.004) as measured by acoustic rhinometry following the allergen dose of 12.5 μg. Slight changes in complaints were observed using the visual analog scale. Exposure to the widespread food allergens (including powdered cow's milk allergens) presents a potential risk of positive response in non-sensitized individuals., Conclusions: Further studies on dose standardization are necessary in the study area., Competing Interests: The authors declare no conflict of interest., (Copyright: © 2023 Termedia Sp. z o. o.)

- Abstract
Differential diagnosis plays a key role in diagnosing specific types of allergic rhinitis. The method involving allergen-specific immunoglobulin E (sIgE) detection in nasal lavage fluid, which has continually been the object of standardization efforts, is characterized by high specificity/sensitivity and plays a special role in diagnosing local allergic rhinitis. This article is a systematic review of the literature on the methodology, standardization, and use of sIgE detection in nasal lavage fluid in patients undergoing diagnostic tests for allergic rhinitis., Competing Interests: The authors declare no conflict of interest., (Copyright: © 2022 Termedia Sp. z o. o.)

- Abstract
Establishing links between serum thyroid hormone panel and triglyceride (TG) concentrations with non-invasively obtained measurements of anthropometric parameters of young women may provide preliminary knowledge about the homeostasis of metabolic processes and body composition and about the strategic role of the tested parameters as early screening tests for assessing the health status of apparently healthy women in the period preceding pregnancy. The study was conducted in 381 healthy female students (aged 18-26 years, mean ± SD = 22.1 ± 1.3). Anthropometric indices (BMI, waist-to-hip ratio, FAT%) were calculated and serum concentrations of thyroid hormones (TSH, fT3, fT4) were determined using electrochemiluminescence immunoassays and serum triglycerides (TG) with a commercially available test. No association was established between serum TSH and anthropometric indices in healthy young women. Increased serum concentrations of fT4, fT3 and TG were found in overweight subjects, i.e. BMI > 24.9 kg/m
2 (p < 0.05). A significant negative association between fT3 and TG was found in underweight subjects (r = - 0.258, p = 0.049) and a significantly positive association in normal-weight subjects (r = 0.139, p = 0.019). In healthy young women differences in BMI are not related to thyroid function. The opposite directions between the associations fT3 vs TG in underweight compared to normal-weight young prepregnant females may suggest dependencies of fT3 and TG in the regulation of specific BMI-dependent metabolic processes., (© 2022.

- Abstract
Local allergic rhinitis, defined as a localized allergic response of the nasal mucosa in the absence of systemic atopy, poses a considerable clinical issue due to its prevalence. The gold standard in local allergic rhinitis diagnostics is primarily the patient's history taking and nasal allergen provocation testing or, alternatively, the basophil activation test, described as "an allergic reaction in a test tube"., Competing Interests: The authors declare no conflict of interest., (Copyright © 2022 Termedia.)

- Abstract
The paradigm of how we manage allergic rhinitis is shifting with a growing understanding that it is a complex process, requiring a coordinated effort from healthcare providers and patients. Pharmacists are key members of these integrated care pathways resolving medication-related problems, optimizing regimens, improving adherence and recommending therapies while establishing liaisons between patients and physicians. Community pharmacists are the most accessible healthcare professionals to the public and allergic rhinitis is one of the most common diseases managed by pharmacists. Allergic Rhinitis and its Impact on Asthma (ARIA) guidelines developed over the past 20 years have improved the care of allergic rhinitis patients through an evidence-based, integrated care approach. In this paper, we propose an integrated approach to allergic rhinitis management in community pharmacy following the 2019 ARIA in the pharmacy guidelines.

- Abstract
Background: Today no established biomarkers are available for the early diagnosis of takotsubo syndrome and its differentiation from ST-segment elevation myocardial infarction. We hypothesized that copeptin and copeptin/NT-proBNP ratio may serve a routine marker combination for non-invasive differentiation., Methods: The study compared the serum concentrations of copeptin, troponin I (TnI) and NT-proBNP in 19 consecutive women diagnosed with takotsubo syndrome according to the Mayo Clinic criteria and 10 consecutive women diagnosed with ST-segment elevation myocardial infarction., Results: Copeptin concentrations were significantly lower in patients with takotsubo syndrome than in patients with ST-segment elevation myocardial infarction. The diagnostic accuracy to distinguish takotsubo syndrome from ST-segment elevation myocardial infarction is highest for copeptin/NTproBNP ratio, copeptin/TnI at admission ratio and copeptin alone (AUC 0.8713, 0.8538, 0.8480, respectively)., Conclusions: The serum copeptin to NTproBNP ratio could be an additional tool in the non-invasive differentiation between takotsubo syndrome and ST-segment elevation myocardial infarction. However, further researches are needed.

- Abstract
Cationic antimicrobial peptides represent a promising therapeutic option against multidrug-resistant bacteria for the treatment of local infections. However, due to their low stability and potential toxicity, there are limited possibilities for their application in clinical practice. In this study, different poly(ε-caprolactone) (PCL) microparticles (MPs) loaded with citropin 1.1 (CIT) were investigated in order to demonstrate the effect of the polymer microstructure on the encapsulation efficiency ( EE ) and kinetics of the peptide release from the newly developed devices. The characteristics of the new systems in terms of surface morphology, particle size, EE and zeta potential analysis, as well as the haemolytic activities of the peptide were investigated. The in vitro release kinetics of CIT from the MPs was also investigated. CIT loading was favoured by a high content of negative charged linear polymer chains in the PCL structure. The presence of non-charged, amorphous macrocycle domains results in faster degradation of the PCL matrix. Depending on the crystallinity of the PCL, the peptide release exhibited a near-zero-order or near-first-order profile with no “burst release”. The results indicated that CIT-loaded PCL MPs could potentially be a promising drug delivery system (DDS) for the treatment of local infections.

- Abstract
Background: The biochemical confirmation of myocardial infarction is based on cardiac troponin (cTnI or cTnT) determination. Recent scientific results suggested that microRNAs (miRNAs) might become a new biomarker of tissue injury., Aim: To evaluate the release kinetics of circulating heart-specific miRNA-208a and also to test the hypothesis that miRNA-208a can serve as an accessible, diagnostically sensitive plasma biomarker of ST-elevation acute myocardial infarction (STEMI)., Methods: Nineteen STEMI patients (four women and 15 men, aged 44-85 years), 12 patients with stable coronary artery disease (CAD), and eight patients with a negative observation of CAD as a control group were studied. Blood samples were collected on admission and at three, six, 12, 24, and 48 h afterwards; in the CAD and control group blood samples were taken only once. Plasma levels of miRNA-208a determined by real-time polymerase chain reaction and their relative fold changes were calculated. cTnI and creatinine kinase (CK)-MB mass were also measured in the patients’ serum samples., Results: miRNA-208a was increased in STEMI patients at the time of admission and nearly undetectable in CAD patients and controls. The peak of miRNA-208a was observed at 3 h after reperfusion (p < 0.001). The traditional biomarkers (cTnI and CK-MBmass), which increase later in comparison to miRNA-208a reaching the maximum concentrations 6 h after reperfusion, were observed. Circulating miRNA-208a levels strongly correlated with cTnI and CK-MBmass released from the infarcted area., Conclusions: These results demonstrate that plasma miRNA-208a is an interesting and promising candidate for a new biomarker released early after onset of myocardial infarction.

- Abstract
Background: Approximately 40-60% of patients with acute coronary syndrome (ACS) have normal cardiac troponin I (cTnI) concentrations on admission. Ischaemia modified albumin (IMA) has been suggested as a new biomarker of myocardial ischaemia., Methods: A total of 43 patients presenting with symptoms suggestive of ACS but with normal (< 0.1 μg/L) cTnI concentrations and 45 healthy subjects were studied. The patients from the study group were divided into two groups: STEMI (n = 28) and NSTEMI (n = 15). All these patients were undergoing percutaneous coronary intervention (PCI) with stenting. The concentrations of cTnI, myoglobin and IMA were determined on admission and 4 h after PCI., Results: Mean (SD) IMA concentrations were higher in patients with ACS (114.39 ± 25.18 U/ml) as compared to the control group (96.24 ± 6.28 U/ml, p < 0.005). IMA concentrations ≥ 104.0 U/ml demonstrated 72.1% sensitivity and 75.6% specificity for the diagnosis of ACS. The area under the receiver operator characteristic curve was 0.766 (95% CI 0.664-0.868) for ACS patients (NSTEMI + STEMI). In both groups increased median (IQR) cTnI concentration after PCI was observed (STEMI patients to 65.4 (10.9-106.9) μg/L and NSTEMI to 17.6 (0.77-84.0) μg/L). In contrast, no increase in IMA concentration was observed., Conclusions: IMA may be a useful biomarker for the identification of ACS patients presenting with typical acute chest pain and/or abnormal electrocardiograms but negative cTnI.

- Abstract
Background: The aim of the present study was to assess the effects of zinc or copper and polyphenolic compounds on the 8-isoprostaglandin F2α concentration in the serum and urine of rats with mammary cancer (adenocarcinoma) induced with 7,12-dimethylbenz[a]antracene. The research focused on the kinetics of alterations in urinary 8-isoPGF2α at the early stage of carcinogenesis as well as the influence of dietary factors on the process. The impact of selected compounds on the intensity of DMBA--induced carcinogenesis was also assessed., Result and Conclusions: Administration of DMBA, a compound that inducers mammary tumors in experimental animals, increased the serum and urinary 8-isoPGF2α levels in study rats. In the rat model, diet supplementation with zinc, combined with selected polyphenolic compounds (resveratrol or genistein) yielded a statistically significant decrease in the rat serum and urinary biomarker concentration with a simultaneously significant stimulation of carcinogenesis.The results indicate that there is an inverse correlation between the intensity of DMBA-induced carcinogenicity and the level of 8-isoPGF2α in urine and serum of rats.

- Abstract
The ticks Ixodes ricinus were collected during three growing seasons in forested areas of north-western Poland. The ticks were collected by flagging at 30 sites. The specimens collected (nymphs and adults) were subjected, after an appropiate treatment, to indirect immunofluorescence analysis (IFA). In addition, effects of temperature and atmospheric precipitation on the tick infection with the spirochaete Borrelia burgdorferi were investigated based on data supplied by the Institute of Meteorology. A total of 8519 individuals of I. ricinus were collected at the sampling sites within May-October of three consecutive years. The pool of individuals obtained consisted of 7356 nymphs, 559 females, and 604 males. The B. burgdorferri prevalence varied rather widely, from 10 to 19%. Compared to nymphs, adult individuals showed a higher infection rate. A relationship between infection rate and I. ricinus activity in different years and months was studied in detail. The boreliosis risk was found to increase with increasing tick activity. On the other hand, no correlation was found between the meteorological parameters (temperature, precipitation), tick abundance, and the B. burgdorferi infection rate.

- Abstract
The aim of the study was to evaluate the total IgE levels and correlation between total IgE concentration in CF and allergy rhinitis patients and in healthy donors, as well as estimation of the activity of some groups of allergens by measurement of specific IgE concentration. The purpose of the study was to estimate correlation between concentration of specific IgE and skin prick tests. The concentration of total and specific IgE was measured by immunoassay. The study groups contained 16 with CF and 10 with allergy rhinitis patients, the control group contain 15 healthy donors. The highest concentration of total IgE we noted in rhinitis subjects, statistically higher than in CF patients and in the control group. The analysis of the concentration of specific IgE showed that allergens as dermatophagoides, food and grasses are the most effective in CF patients. We did not found correlation between specific IgE level and skin prick tests.
