Consumer tests are classified in terms of the location of testing as laboratory tests or central location tests (CLTs) and home use tests (HUTs). CLT is generally used in sensory tests due to the ease of test control, whereas HUT has higher validity because of real consumption. However, the lack of test control in HUT is a major issue. In order to investigate the error occurrence and efforts required to minimize errors, three groups of tests were designed differing time and order control and evaluation was conducted using six snacks with texture differences. Errors related to time, order, and consumer or sample number were higher for more controlled conditions, however, most errors were recoverable using identification information except for cases of no response. Additionally, consumers preferred to consume all snacks in the evening at home, which differed from the typical 9 a.m. to 6 p.m. evaluation time in CLT. However, the timing differed for consumers with self-reported snacking time. The research title that included the term ‘home’ might have influenced the participants’ choice of location for evaluation. Overall, there was no significant difference between the results of groups despite different time and order controls, which could increase the applicability of HUT.

AbstractObjectiveThe present study investigated the impact of salt labelling and repeated in-home consumption on liking of reduced-salt soups.DesignParticipants received a chicken noodle soup to be consumed twice weekly at home for 5 weeks. Three soups were included: (i) regular-salt soup as available on the market; (ii) 22 %-reduced-salt soup; and (iii) 32 %-reduced-salt soup. The soups were tasted blind or with the label: ‘same great taste, less salt and more herbs’. In total, there were six experimental groups. All groups received the same soup over the whole period. Desire and liking were measured at each time of consumption.SettingIn-home and central location test.SubjectsFrench consumers (n 646).ResultsThere was no significant difference in liking between the three soups when consumed at home, whereas the reduced-salt soups were less liked than the regular-salt soup in the central location test. Labelling did not boost liking scores, which is probably explained by the fact that all soups were similarly liked when eaten at home.ConclusionsThe surprising results of the present study in France suggest that a salt reduction of up to 32 % in a chicken noodle soup did not affect long-term liking score as assessed by consumers at home. In addition, initial liking measured at the central location was not predictive of liking after repeated in-home consumption. How far we can go in reducing salt in other products without compromising product quality, and how this impacts consumers’ choice behaviour and in turn table salt use at home, are still unanswered questions.

ABSTRACT The distributions of 13 variables based on 10 laboratory tests measuring thyroid function were studied in euthyroid controls and in patients with toxic diffuse or toxic multinodular goitre. Density functions were fitted to the empirical data and the goodness of fit was evaluated by the use of the χ2-test. In a few instances there was a significant difference but the material available was in some respects too small to allow a very accurate estimation. The normal limits for each variable was defined by the 2.5 and 97.5 percentiles. It appears that in some instances these limits are too rigorous from the practical point of view. It is emphasized that the crossing point of the functions for euthyroid controls and hyperthyroid patients may be a better limit to use. In a preliminary analysis of the diagnostic efficiency the variables of total or free hormone concentration in the blood proved clearily superior to all other variables.

The aim of the study is to determine the effect on death anxiety of loneliness in the elderly during the COVID-19 pandemic. The population of this study that is descriptive and cross-sectional type consist of 354 elderly who meet the inclusion criteria from three different associations operating for charitable purposes in a city center located in north-west Turkey. The average score of Loneliness Scale of Elderly (LSE) of the elderly was determined as 11.39 ± 5.31, and the average score of Death Anxiety Scale (DAS) of the elderly was determined as 8.54 ± 4.82. According to these results, it was found that the elderly experienced acceptable levels of loneliness and moderate death anxiety. A statistically significant difference was found in the LSE and DAS scores of the elderly according to their age, marital status, education status, chronic illness status and living at home with relatives. In addition, during the COVID-19 epidemic, the scale scores of the elderly who have increased worries, who have a hobby at home, and who communicate with their relatives via social media/mobile phones were found to be statistically significant (p < 0.05).

Abstract Objective The main aim of the study was to assess the impact of COVID-19 pandemic on athletes preparing for the Tokyo 2021 Paralympic Games during 1 month of lockdown in Poland. The study involved 166 athletes (106 male, 66 female), members of either the Polish Paralympic Committee or the Polish Sports Association for the Disabled’Start’, two organizations responsible for managing and regulating sports played by persons with disabilities in Poland. Results Athletes with disabilities have been strongly affected by the pandemic and the resultant lockdown. The majority of respondents reported that they trained at home (88.6%), whereas 60.2% of athletes trained outdoors, and 12% suspended their training regimens altogether. Only 5.4% of athletes had some access to sport facilities. The athletes reduced their weekly training time by almost half (9.4 h/week vs. 5.3 h/week), a statistically significant difference (t = 16.261, p < 0.001).

ABSTRACT: The objective of the current research was to assess seroconversion in dogs immunized with Leishmune® and Leish Tec® vaccines using rapid chromatographic immunoassay DPP® (Dual Path Platform) (DPP CVL) and enzyme immunoassay (EIE) up to one year after the vaccination protocol. The study sample comprised 28 dogs divided into two groups, each group immunized with an anti-CVL vaccine and clinically monitored for one year through clinical evaluation and laboratory tests. 22 (78.5%) dog were monitored. During the evaluation time (T1-30 days, T2-6 months, and T3-1 year after vaccination) the results for all dogs were negative for CVL, except for one animal vaccinated with Leish tec® that seroconverted in the DPP CVL test at T2. Subsequent examinations of this dog were negative. Our results showed that in a non-endemic area, even at different evaluation times, dogs vaccinated against CVL with Leishmune® or Leish tec® did not seroconvert in the serological protocol used by the Brazilian Ministry of Health (DPP/EIE).

Head Louse Infestation

Context.During the late 1990s, insecticide resistance had rendered a number of treatment products ineffective; some companies saw this as an opportunity to develop alternative types of treatment. We investigated the possibility that a surfactant-based lotion containing 10% cocamide diethanolamine (cocamide DEA) was effective to eliminate head louse infestation.Settings and Design.Initialin vitrotesting of the lotion formulation versus laboratory reared body/clothing lice, followed by two randomised, controlled, community-based, assessor blinded, clinical studies.Materials and Methods.Preliminary laboratory tests were performed by exposing lice or louse eggs to the product using a method that mimicked the intended use. Clinical Study 1: Children and adults with confirmed head louse infestation were treated by investigators using a single application of aqueous 10% cocamide DEA lotion applied for 60 min followed by shampooing or a single 1% permethrin creme rinse treatment applied to pre-washed hair for 10 min. Clinical Study 2: Compared two treatment regimens using 10% cocamide DEA lotion that was concentrated by hair drying. A single application left on for 8 h/overnight was compared with two applications 7 days apart of 2 h duration, followed by a shampoo wash.Results.The initial laboratory tests showed a pediculicidal effect for a 60 min application but limited ovicidal effect. A longer application time of 8 h or overnight was found capable of killing all eggs but this differed between batches of test material. Clinical Study 1: Both treatments performed badly with only 3/23 (13%) successful treatments using cocamide DEA and 5/25 (23.8%) using permethrin. Clinical Study 2: The single overnight application of cocamide DEA concentrated by hair drying gave 10/56 (17.9%) successes compared with 19/56 (33.9%) for the 2 h application regimen repeated after 1 week. Intention to treat analysis showed no significant difference (p= 0.0523) between the treatments. Over the two studies, there were 18 adverse events possibly or probably associated with treatment, most of which were increased pruritus after treatment.Conclusions.Cocamide DEA 10% lotion, even when concentrated by hair drying, showed limited activity to eliminate head louse infestation.

Background/Aim. Elevation in adduction is the most common pattern of vertical strabismus, and it is mostly treated with surgery. The results of weaking of inferior oblique muscle are very changeable. The aim of this study was to evaluate binocular vision using sensory tests before and one and six months after the surgery. Methods. A total of 79 children were divided in two groups: the first, with inferior oblique muscle of overaction (n = 52), and the second with dissociated vertical deviation (DVD), and primary inferior oblique muscle overaction (n = 27). We tested them by polaroid mirror test (PMT), Worth test at distance and near, fusion amplitudes on sinoptofore, Lang I stereo test and Wirt-Titmus stereo test. We examined our patients before and two times after the surgery for vertical strabismus. Results. Foveal suppression in the group I was found in 60.5% of the patients before, and in 56.4% after the surgery. In group II Foveal suppression was detected in 64.7% of the patients before, but in 55.6% 6 months after the surgery with PMT. Worth test revealed suppression in 23.5% of the patients before, and in 40.7% after the vertical muscle surgery. Parafoveal fussion persisted in about 1/3 of the patients before the surgery, and their amplitudes were a little larger after the surgery in the group I patients. Lang I stereo test was negative in 53.9% before and 51.9% after the surgery in the group I, and in 48.2% of the patients before and after the surgery in the group II patients. Wirt-Titmus stereo test was negative in 74.5% of the patients before and in 72.9% after the surgery in the group I, but in the group II it was negative in 70.8% before and in 68.0% of the patients 6 months after the surgery. Conclusion. Binocular responses were found after surgery in 65.7% of the patients the group I and in 55.6% patients the group II. There was no significant difference between these two groups, but binocular responses were more often in the patients of the group I.

The research entitled The Effect of Substitution of Soybean Flour on Biscuit Quality is a type of research using a quantitative approach with an experimental method. The purpose is to know the effect of quality biscuits with soybean flour substitution with a different percentage that is equal to 50%, 25% and 10% viewed from the aspect of colour, flavour, aroma and texture. The experiments used 3 different types of treatment on the percentage of soy flour used ie, biscuit A with 50% soy flour, biscuit B with 25% soy flour, and C biscuits with 10% soy flour. Methods of data collection using subjective assessment of sensory tests taken from the results of a panellist assessment that includes assessment of colour, aroma, taste and texture on biscuits. The panel of researchers was 30 people taken by random sampling technique with considerations that included panellist knowledge about the sensory properties of biscuits in general. Methods of data analysis to test the hypothesis using the analysis of single classification variables and Tukey test, previously conducted precariat test that is homogeneity test and normality test. The result of the research with Anova test seen from the color aspect shows that (significant value (p-value) <0,05 = 0,000 <0,05) shows that there is significant difference from three substitution biscuit substitution biscuit, while from aroma aspect shows significant (p-value) <0,05 = 0,008 <0,05) indicated that there were significant differences from the three soybean substitution biscuit samples. Seen from the texture aspect showed (significant value (p-value) <0,05 = 0,000 <0,05) indicated that there was significant difference from three sample of soybean substitution biscuit. In terms of taste taste (significant value (p-value) <0.05 = 0.005 <0.05) indicates that there are significant differences from the three soybean substitution biscuit samples.

Aim. To study the peculiarities of asking for medical care by patients from among those dead at home, who had been under follow-up observation. Materials and methods. The data, received from ambulatory medical records of 100 dead at home patients with follow-up, were analyzed using the methods of descriptive and inductive statistics. Results. A mean age of death was 74.9 ± 13.4 years, men - 65.8 ± 14.1 years, women - 79.2 ± 10.9 years. Cardiovascular diseases were the cause of follow-up observation in 78 % of cases and the cause of death in 85 %; in 30 % of patients the disease was detected while carrying out prophylactic medical examination. A mean duration of disease by the moment of death was 13.0 ± 8.0 years, among pensioners 13.7 ± 8.5 years, in able-bodied persons 9.6 ± 4.3 years. A mean duration of follow-up observation was 9.2 ± 5.8 years. An average number of planned visits was 2.8 ± 0.89, but the number of real visits during the last year of follow-up observation was 2.4 ± 1.2. Disability was registered in 77.6 % of patients, concomitant diseases - in all patients. For the last year, exacerbations were recorded in 92 % of patients, emergency calls - in 80 %, hospitalization events - 52 %, including 55.8 % - urgent ones. Conclusions. The absence of significant difference regarding the duration of disease between pensioners and able-bodied patients (т = 0.16, р = 1.43) as well as the absence of correlation between the age and duration of disease (χ2 = 0.19, p = 0.2) indirectly prove the influence of duration of disease on its outcome, but not the age. Attendance, characterizing clinical loyalty to treatment, does not depend on age (χ2 = -0.19, р = 0.18), sex (т = 1.0, р = 0.32), way of detecting disease (f = 0.9, p = 0.4), class of main disease (f = 0.91, p = 0.44), duration of disease (χ2 = -0.13, р = 0.49), exacerbations (χ2 = -0.17, р = 0.24), concomitant diseases (χ2 = 0.006, р = 0.9). The number of emergency calls, hospitalizations, urgent hospitalizations does not depend on duration of follow-up observation, regularity and number of real visits to a doctor (p > 0.05) that indicates unsatisfactory quality of follow-up observation.
