Perceived Risk of Fish Consumption in a Low Fish Consumption Country
Among the numerous health benefits of fish consumption, perhaps the most recognized is the role of omega-3 fatty acids in the prevention of cardiovascular disease. Cardiovascular disease is prevalent in Hungary, which has the lowest fish consumption in Europe. Increasing fish consumption is the aim of most European countries and given the high incidence of cardiovascular disease in Hungary, it is of particular importance. A significant reduction of the VAT for fish in 1 January 2018 aimed to increase fish consumption in Hungary. However, despite reduced VAT, the price of fish in Hungary rose from 2017 to 2018. The aim of our research is to explore perceived risks that serve to exacerbate Hungarian consumers’ low fish consumption, and to measure their effects to identify potential strategies to most effectively increase fish consumption. We applied partial least squares structural equation modeling (PLS-SEM) to analyze responses provided by 1042 survey participants (collected with face-to-face interviews, using quota sampling in 2014) to explore variables of fish consumption associated with perceived risk including psychological, physical, social, and functional risks. Our model is the first one that applies detailed perceived risk categories to measure those effects on low fish consumption. The results indicate that psychological risk associated with negative past experiences have both a direct, and through functional risk, an indirect significant negative effect on fish consumption. Conversely, neither social nor physical risk impede Hungarian fish consumption. We conclude that the seafood industry could benefit from targeted interventions that seek to reduce functional risk-perception of the person responsible for preparing fish in the household
Detecting the Bitterness of Milk-Protein-Derived Peptides Using an Electronic Tongue
Bitterness is a considerable limiting factor for the application of bioactive peptides in the food industry. The objective of this study was to compare the level of bitterness of milk-protein-derived peptides using an electronic tongue (E-tongue). Liquid milk protein concentrate (LMPC) was prepared from ultra-heat-treated skimmed cow’s milk. It was initially hydrolyzed with different concentrations of trypsin, namely, 0.008 g·L−1, 0.016 g·L−1 and 0.032 g·L−1. In a later exercise, tryptic-hydrolyzed LMPC (LMPC-T) was further hydrolyzed using Lactobacillus bulgaricus and Streptococcus thermophilus. The effect of glucose in microbial hydrolysis was studied. The bitterness of peptides was evaluated with respect to quinine, a standard bittering agent. The level of bitterness of the peptides after microbial hydrolysis of LMPC-T (LMPC-T-F and LMPC-T-FG) was evaluated using a potentiometric E-tongue equipped with a sensor array that had seven chemically modified field-effect transistor sensors. The results of the measurements were evaluated using principal component analysis (PCA), and subsequently, a classification of the models was built using the linear discriminant analysis (LDA) method. The bitterness of peptides in LMPC-T-F and LMPC-T-FG was increased with the increase in the concentration of trypsin. The bitterness of peptides was reduced in LMPC-T-FG compared with LMPC-T-F. The potential application of the E-tongue using a standard model solution with quinine was shown to follow the bitterness of peptides
Eliciting vulnerable consumers’ preferences for redundant vs. organic and functional claims: Experimental auction studies among young and older adults
The growing use of redundant claims on food products pose a risk for organic and functional food producers among others, as it can mislead consumers in their products’ evaluations. Redundant claims refer to marketing statements that highlight qualities or attributes that are expected or should be inherent to the product. Previous studies reveal that consumers are generally willing to pay more for redundantly claimed products. In this study, preferences are analyzed for organic, functional, and redundantly labeled apple juice among specific consumer groups, namely young and old adults. To elicit individual monetary preferences a lab experiment and a field study were conducted with 147 younger (average age: 21 years) and 131 older participants (average age: 70 years), in both studies an incentive compatible technique was applied. Results showed that either younger and older consumers are willing to pay higher prices for organic, functional, and redundantly claimed apple juices. Perceived healthiness was a significant factor in increasing preferences for all the added valued products in the case of younger participants, but health only influenced preferences of organic and functional apple juice among older participants. Preferences of redundantly claimed and organic products were similar in the case of young participants, as functional and redundantly claimed juices preferences in the case of older participants
Audiological findings in pediatric perineal allergic rhinitis (house dust mite allergy) patients
Allergic rhinitis is the type 1 hypersensitivity
reaction of the nasal mucosa and its primary mediator is Ig
E. It is most frequently observed in children and adolescents.
Our purpose in this study is to investigate the impact
of allergy on hearing functions in children with perineal
allergic rhinitis (house dust mite allergy). 50 perineal
allergic rhinitis (house dust mite allergy) patients (33 male,
17 female patients, aged between 6 and 15, average age
10.4) and 20 control patients (12 male, 8 female, aged
between 6 and 15, average age 11.2) underwent high frequency
pure tone audiometry, acoustic reflex, otacoustic
emission (OAE) and auditory brainstem potentials to assess
their auditory functions. No statistically significant difference
was detected between the study group and the control
group with respect to their hearing thresholds
(250–16,000 Hz). No statistically significant difference
was detected as a result of the comparison between the
study group and control group in terms of their signal–
noise ratios at Distortion Product OAE in all frequencies
(996–8,004 Hz). No statistically significant difference was
detected between the study group and the control group in
terms of the 1st, 3rd and 5th wave latencies and 1–3, 3–5
and 1–5 inter-peak values. This study is the first study
where the audiological functions of the pediatric perineal
allergic rhinitis (house dust mite allergy) patients were
assessed. No significant difference was detected between
the group of pediatric perineal allergic rhinitis (house dust
mite allergy) patients and th

Gastrostomy in hospitalized patients with acute stroke: "NoroTek" Turkey point prevalence study subgroup analysis
Objective: Nutritional status assessment, dysphagia evaluation and enteral feeding decision are important determinants of prognosis in acute neurovascular
diseases.
Materials and Methods: NöroTek is a point prevalence study conducted with the participation of 87 hospitals spread across all health sub regions of Turkey
conducted on 10-May-2018 (World Stroke Awareness Day). A total of 972 hospitalized neurovascular patients [female: 53%, age: 69±14; acute ischemic stroke
in 845; intracerebral hematoma (ICH) in 119 and post-resuscitation encephalopathy (PRE) in 8] with complete data were included in this sub-study.
Results: Gastrostomy was inserted in 10.7% of the patients with ischemic stroke, 10.1% of the patients with ICH and in 50% of the patients with PRE.
Independent predictors of percutaneous endoscopic gastrostomy (PEG) administration were The National Institutes of Health Stroke Scale score at admission [exp
(β): 1.09 95% confidence interval (CI): 1.05-1.14, per point] in ischemic stroke; and mechanical ventilation in ischemic [exp (β): 6.18 (95% CI: 3.16-12.09)] and
hemorrhagic strokes [exp (β): 26.48 (95% CI: 1.36-515.8)]. PEG was found to be a significant negative indicator of favorable (modified Rankin’s scale score 0-2)
functional outcome [exp (β): 0.032 (95% CI: 0.004-0.251)] but not of in-hospital mortality [exp (β): 1.731 (95% CI: 0.785-3.829)]. Nutritional and swallowing
assessments were performed in approximately two-thirds of patients. Of the nutritional assessments 69% and 76% of dysphagia assessments were completed
within the first 2 days. Tube feeding was performed in 39% of the patients. In 83.5% of them, tube was inserted in the first 2 days; 28% of the patients with
feeding tube had PEG later.
Conclusion: The NöroTek study provided the first reliable and large-scale data on key quality metrics of nutrition practice in acute stroke in Turkey. In terms
of being economical and accurate it makes sense to use the point prevalence method.Amaç: Akut nörovasküler hastalıklarda nütrisyonel durum ve disfaji değerlendirmesi ve enteral beslenme kararı önemli prognoz belirleyicilerindendir.
Gereç ve Yöntem: NöroTek, 10 Mayıs 2018’de (Dünya İnme Farkındalık Günü) Türkiye’nin tüm sağlık alt bölgelerine yayılmış 87 hastanenin katılımıyla
gerçekleştirilen bir nokta prevalans çalışmasıdır. Hastanede yatan ve bu alt çalışma için toplanan verisi tam olan toplam 972 nörovasküler hasta (kadın: %53, yaş:
69±14 yıl; 845’i akut iskemik inme; 119’u intraserebral hematom ve 8’i post-resüsitasyon ensefalopatisi) analiz edildi. Bulgular: Gastrostomi iskemik inmeli hastaların %10,7, intraserebral kanamalıların %10,1 ve post-resusitasyon ensefalopatisi olanların %50’sine uygulanmıştır.
Perkütan endoskopik gastrostomi (PEG) gereksiniminin bağımsız belirleyicileri, iskemik inme grubunda kabul NIHSS [exp (β): 1,09, %95 güven aralığı (GA):
1,05-1,14, puan başına] ile hem iskemik hem de hemorajik inmelerde mekanik ventilasyon uygulanmış olmasıdır [iskemik için: exp (β): 6,18, %95 GA: 3,16-
12,09] ve hemorajik inme için: [exp (β): 26,48, 95% GA: 1,36-515,8]. İnme olgularında PEG uygulaması hastane içi mortalite için bağımsız belirleyici değildi
[exp (β): 1,731, 95% GA: 0,785-3,829]. Ancak, PEG uygulanmış olması taburculuk esnasında iyi prognoza (modifiye Rankin skoru 0-2) sahip olabilme için
anlamlı bir negatif etmen olarak bulundu [exp (β): 0,032, %95 GA: 0,004-0,251]. Hastanede yatan nörovasküler hastaların yaklaşık üçte ikisinde malnütrisyon
ve yutma bozukluğu açısından değerlendirme yapılmıştı. Nutrisyonel status değerlendirmesinin %69’u ve disfaji değerlendirmesinin %76’sı ilk 48 saat içinde
gerçekleştirilmişti. Tüple enteral nütrisyon uygulama oranı %39’du. Beslenme tüplerinin %83,5’i ilk 2 gün içinde yerleştirilirken beslenme tüpü olan hastaların
%28’ine daha sonra PEG açılmıştı.
Sonuç: NöroTek çalışması ile Türkiye’de hastanede yatan akut inme hastalarında nutrisyonel uygulamaların temel kalite ölçütlerine ilişkin ilk güvenilir ve büyük
ölçekli veri sağlanmıştır. Ekonomik olması ve doğruluğu açısından nokta yaygınlık yönteminin bu tip verilerin temini için daha fazla kullanılması mantıklıdır
Atrial Fibrillation Management in Acute Stroke Patients in Türkiye: Real-life Data from the NöroTek Study
Objective: Atrial fibrillation (AF) is the most common directly preventable cause of ischemic stroke. There is no dependable neurology-based data on the spectrum of stroke caused by AF in Turkiye. Within the scope of NoroTek-Turkiye (TR), hospital-based data on acute stroke patients with AF were collected to contribute to the creation of acute-stroke algorithms.Materials and Methods: On May 10, 2018 (World Stroke Awareness Day), 1,790 patients hospitalized at 87 neurology units in 30 health regions were prospectively evaluated. A total of 929 patients [859 acute ischemic stroke, 70 transient ischemic attack (TIA)] from this study were included in this analysis.Results: The rate of AF in patients hospitalized for ischemic stroke/TIA was 29.8%, of which 65% were known before stroke, 5% were paroxysmal, and 30% were diagnosed after hospital admission. The proportion of patients with AF who received "effective" treatment [international normalization ratio >= 2.0 warfarin or non-vitamin K antagonist oral anticoagulants (NOACs) at a guideline dose] was 25.3%, and, either no medication or only antiplatelet was used in 42.5% of the cases. The low dose rate was 50% in 42 patients who had a stroke while taking NOACs. Anticoagulant was prescribed to the patient at discharge at a rate of 94.6%; low molecular weight or unfractionated heparin was prescribed in 28.1%, warfarin in 32.5%, and NOACs in 31%. The dose was in the low category in 22% of the cases discharged with NOACs, and half of the cases, who received NOACs at admission, were discharged with the same drug.Conclusion: NoroTekTR revealed the high but expected frequency of AF in acute stroke in Turkiye, as well as the aspects that could be improved in the management of secondary prophylaxis. AF is found in approximately one-third of hospitalized acute stroke cases in Turkiye. Effective anticoagulant therapy was not used in three-quarters of acute stroke cases with known AF. In AF, heparin, warfarin, and NOACs are planned at a similar frequency (one-third) within the scope of stroke secondary prophylaxis, and the prescribed NOAC dose is subtherapeutic in a quarter of the cases. Non-medical and medical education appears necessary to prevent stroke caused by AF
