This study assessed whether methods for capturing the pedestrian experience of outdoor lighting, previously evaluated in a full-scale laboratory, were applicable in a real-world setting. It applied an approach capturing the human response to outdoor lighting in a systematic way, by assessing perception, evaluation and behaviour in the lit environment. The study involved 81 participants from two age groups (Young—n: 48, mean age: 26, 63% women; Elderly—n: 33, mean age: 69, 67% women) and was carried out on a pedestrian path in a park in the centre of Malmö, Sweden, in the evenings during wintertime. Two LED lighting applications, differing in light distribution, uniformity and horizontal illuminance, were presented, and the pedestrians’ perception (facial expression recognition and sign reading), evaluation (arousal, valence and perceived outdoor lighting quality) and behaviour (pedestrian flow) were assessed. The results from the perceptual tasks differed significantly between the lighting applications, in favour of the lighting application with greatest uniformity and horizontal illuminance. There was a significant difference in sign reading distance between the two age groups. The methods applied in this study are feasible to administer and could be used to assess lighting solutions in order to capture the needs of vulnerable groups.

Closely related Swedish and German both mark information status of referents morphologically, though little is known about its acquisition. This study investigates character introductions in the narratives of 4- and 6-year-old Swedish–German bilinguals ( N = 40) in both languages, elicited with MAIN Cat/Dog. We analyse effects of age group, language and animacy (human vs nonhuman characters) on the type of referring expression (indefinite NP and pronoun), as well as effects of language proficiency and exposure on the use of indefinite NPs for each language. We also explore which syntactic constructions indefinite NPs occur in. A significant difference was found between the two age groups, but not between languages. No effect was found of language skills or exposure. Four-year-olds used more pronouns and a lower proportion of indefinite NPs than 6-year-olds. Pronouns were more frequent for the human character than for nonhuman animate characters. Whilst animacy (humanness) promoted the use of pronouns, it did not affect the choice of morphological form for lexical NPs (indefinite/definite). The age groups differed in how indefinite NPs were used. Four-year-olds produced fewer narrative presentations (where a character is introduced as part of a typical story opening, e.g. Once upon a time there was a cat) than 6-year-olds, and more labellings (with only an NP, or a clausal predicative, e.g. That’s a cat). Qualitative analyses suggest that the children’s indefinite NPs in labelling constructions can be both referential (when setting the narrative scene), and type-denoting (when naming referents in individual pictures). Whilst the children’s abilities to introduce story characters develop measurably from 4 to 6 years in Swedish and German, appropriateness of character introductions not only depends on whether an indefinite NP is chosen, but also on the syntactic construction this indefinite NP is used in.

ABSTRACTThe study was performed in the Czech Republic during 2007 to 2009. OfEscherichia coliisolates from 275 children aged 6 weeks, 36% (n= 177) were resistant to 1 to 7 antibiotics. Of isolates from 253 children aged 6 to 17 years, 24% (n= 205) were resistant to 1 to 5 antibiotics. There was no significant difference in the prevalences of antibiotic-resistantE. coliisolates between these groups of children, even though the consumptions of antibiotics were quite different.

IntroductionIn the Tunisian cultural context, the mother is in charge of childcare, housekeeping and the well-being of the whole family, which can lead to exhaustion and depression.ObjectiveTo estimate the frequency of depression among mothers aged between 20 and 40 years, its consequences and the possible solutions.MethodTransversal study using an anonymous questionnaire of 26 questions published through social media sites to mother with young aged children.ResultsThree hundred and twenty-seven mothers participated in the study: 20% of them aged between 20 and 30 years and 80% between 30 and 40. Ninety-seven percent of the participants were married; 96% of them had university education. Seventy-nine percent of them were working mothers and 50% of them did not get any help in childcare. Forty-two percent of the participants had only 1 child, 49% had 2 children, 8% 3 children and only 1 mother had 4 children. Depressive symptoms were present in 73% of the participants and were significantly higher among mothers aged between 30 and 40. However, depression was certain in only 36% of them and there was no significant difference between the two age groups. Eighteen percent of the participants noticed an increase in consummation of cigarettes, 31% resorted to tranquilizers, 25% needed sick leaves, and 2% resorted to alcohol use. Less working hours was suggested as a solution in 36% cases, sharing house chores in 30% cases.ConclusionDepression among young mother is a public health problem in Tunisia. It is underestimated and not always treated, which can have a serious impact on the whole family well-being.Disclosure of interestThe authors have not supplied their declaration of competing interest.

Background: This new COVID-19 pandemic challenges health systems around the world; therefore, it is extremely important to determine which patients with COVID-19 can evolve to more severe outcomes. Accordingly, we decided to assess the role that comorbidities play in death from COVID-19. Methods: Two age groups (<60 and ≥ 60 years) were defined for analysis. Decision trees were made to identify which comorbidities had the highest fatality rate (FR). Multiple logistic regressions were performed to measure the association between comorbidities and death. Results: A significant difference was found between the FR of <60 group and ≥ 60 group. The most frequent comorbidity were cardiac diseases and diabetes. The combination of comorbidities with the highest FR was diabetes with kidney disease. Combinations of more than two comorbidities presented higher FR. The comorbidities had higher Odd ratios in the younger group than in the older group. Conclusions: Comorbidities seem to play a greater role in death from COVID-19 in the younger group, while in the ≥ 60 group, age seems to be the most important factor. We assigned a score to the comorbidities and their combinations for both age groups to help the health personnel make decisions.

The article presents a psycholinguistic study of the oral speech of pre-adolescent Russian speakers. The current study compared the quantitative characteristics of speech disfluencies (silent and filled hesitation pauses, false starts, and repetitions among them) on the material of two corpora of oral texts: one of which was an annotated transcript of dialogues of children asged 10-12 solving in pairs a certain problem, and the second corpus consisted of dialogues between adults in the identical situation. Through the comparison of the two corpora, the author aimed at determining differences in speech behavior of two age groups put in the same conditions. The analysis of the collected data showed that there is a statistically significant difference between the two samples in the number of silent pauses and their length between the interlocutors’ utterances, as well as by one of the types of repairs, which may indicate the ongoing development of certain speech skills in children of this age. These results support the theory of late discursive development which indicates the need for further comprehensive research of pre-adolescent children speech, even though this period traditionally is neglected by researchers.

6080 Background: Nasopharyngeal carcinoma (NPC) has a bimodal age distribution with peaks at 15–25 and 40–50 years of age, though it is unclear if the prognosis differs significantly between the two age groups. Here, we compare treatment outcomes between two age groups of patients treated at a single institution. Methods: We retrospectively analyzed the data of 99 NPC patients who received definitive treatment at our institution between March 1985 and June 2004. All patients received a median dose of 66 Gy of external beam radiation therapy and 70% received either concurrent or induction chemotherapy. We compared patient, tumor, and treatment characteristics as well as treatment outcomes in juvenile patients (age = 25 years at diagnosis), versus adult patients (age > 25 years at diagnosis). Survival curves were estimated by the Kaplan-Meier method. Results: There was a significant difference in the ethnic composition between the age groups, with more Asians and fewer Whites and Hispanics in the adult group (see table ). Also, there was a significant difference between the groups in the proportion of patients receiving chemotherapy, especially induction chemotherapy (see table ). There was no difference in the distribution of tumor stage and WHO histology between the two age groups. At a median follow-up for all patients of 42 months (range 4 to 234), there were no statistically significant differences in treatment outcomes between the two age groups although the survival data numerically favored the juvenile patients (see table ). Conclusions: Although there were significant differences in racial distributions and treatment characteristics between the two age groups, treatment outcomes were similar. Aggressive treatment with radiotherapy and chemotherapy resulted in excellent outcomes for both patient populations. No significant financial relationships to disclose. [Table: see text]

In this study, we focus on the usability of pseudo-3D thematic maps (static perspective views) compared with their conventional 2D equivalents. A total of 105 study participants were divided into two groups (12–19 years old and 20–27 years old). A Perspective Taking Test measured their spatial abilities and each participant solved 15 tasks using four thematic maps. We compared map variants to determine which is more suitable for individual tasks. We then examined the differences between the two age groups and tried to find any relationship between the user’s spatial abilities and the number of correct answers. We observed a significant difference regarding the map’s visualization dimension only in one particular task and significant differences between the age groups when they worked with 2D maps. We found a positive correlation between the participant’s level of spatial ability and the number of correct answers.

The purpose of this study was to determine whether a new sustained-release theophylline preparation TheoDur could maintain therapeutic serum theophylline levels in asthmatic children on a 12-hour dosage regimen. Twenty asthmatic children aged 6 to 18 years with a mean of 11.4 years who required continuous theophylline therapy for control of their asthma were enrolled in the study. Each patient's dosage was titrated to achieve a six-hour postdose serum theophylline level between 10 and 20 µg/ml. The patients required a mean ± SEM dose of 10.0 ± 0.54 mg/kg every 12 hours which gave a mean ± SEM six-hour postdose serum theophylline level of 15.65 ± 0.72 µg/ml. At the end of five days on this dosage, the patients were admitted and serum theophylline levels were determined every three hours for 24 hours. The mean ± SEM difference between maximum and minimum serum theophylline levels (ΔTL) for the group was 4.5 ± 0.3 µg/ml. There was not a significant difference in the ΔTL between the two age groups (6 to 9 years, 4.5 ± 0.5 µg/ml and 10 to 18 years 4.5 ± 0.4 µg/ml). In conclusion, TheoDur will maintain therapeutic serum theophylline levels with minimal fluctuations in asthmatic children on a 12-hour dosing schedule.
