Schedule Effect

Ingestion of a meal induces conscious sensations depending of the characteristics of the meal and the predisposition of the eater. We hypothesized that the eating schedule plays a conditioning role, specifically, that an extemporaneous meal is less rewarding than when eaten at the habitual schedule. We conducted a randomized parallel trial in 10 women and 10 men comparing the responses to a consistent savoury lunch-type meal (stewed beans) eaten at the habitual afternoon schedule or at an unconventional time in the morning. Schedule and gender differences were analyzed by repeated measures analysis of covariance. In women, the sensory experience induced by the probe meal, particularly postprandial satisfaction, was weaker when eaten at an unconventional time for breakfast. Men were resilient to the schedule effect and experienced the same sensations regardless of the timing of ingestion; the effect of the eating schedule was significantly more pronounced in women for fullness (F(1,55) = 14.9; p < 0.001), digestive well-being (F(1,36.8) = 22.3; p < 0.001), mood (F(1,12.4) = 13.8; p < 0.001), and anxiety (F(1,11.9) = 10.9; p = 0.001). No differences in the physiological responses induced by the afternoon and morning meals were detected either in women or men. Our data indicate that women are more susceptible to changes in meal schedule than men.

BackgroundMeta-analyses of hippocampal size have indicated that this structure is smaller in schizophrenia. This could reflect a reduction in the size of constituent neurons or a reduced number of neurons.AimsTo measure the size of hippocampal pyramidal neurons in the brains of people with and without schizophrenia.MethodPyramidal neuron size in hippocampal subfields was estimated stereologically from sections taken at 5 mm intervals throughout the whole length of right and left hippocampi from the brains of 13 people with schizophrenia and 16 controls. Results were assessed using repeated-measures analysis of covariance looking for a main effect of diagnosis and gender, and interactions of these with side.ResultsWe were unable to detect significant differences related to diagnosis, gender or side for any hippocampal subfield for this series of cases.ConclusionsFor this series of brains, hippocampal cell size is unchanged in schizophrenia.

Maintaining stable physiological responses may be important for the growth and development of preterm infants. The purpose of our study was to evaluate the effects of olfactory stimulation with maternal breast milk on the occurrence of abnormal physiological responses in preterm infants. With a non-equivalent control group pretest-posttest design, 13 preterm infants in the experimental group and 18 preterm infants in the control group completed the intervention. The intervention was implemented three times a day for 5 days in a row with 2 hours of administration per intervention. The frequency of abnormal physiological responses was assessed over 6 days (one day before intervention administration and 5 days during intervention administration). With repeated-measures analysis of variance, the experimental group showed a significantly lower frequency of apnea than the control group ( p = .021). Olfactory stimulation with maternal breast milk may be an effective nursing intervention for reducing apnea episodes in preterm infants.

Background Perfluorocarbon (PFC) liquids are known to improve gas exchange and pulmonary function in various models of acute respiratory failure. Vaporization has been recently reported as a new method of delivering PFC to the lung. Our aim was to study the effect of PFC vapor on the ventilation/perfusion (VA/Q) matching and relative pulmonary blood flow (Qrel) distribution. Methods In nine sheep, lung injury was induced using oleic acid. Four sheep were treated with vaporized perfluorohexane (PFX) for 30 min, whereas the remaining sheep served as control animals. Vaporization was achieved using a modified isoflurane vaporizer. The animals were studied for 90 min after vaporization. VA/Q distributions were estimated using the multiple inert gas elimination technique. Change in Qrel distribution was assessed using fluorescent-labeled microspheres. Results Treatment with PFX vapor improved oxygenation significantly and led to significantly lower shunt values (P &lt; 0.05, repeated-measures analysis of covariance). Analysis of the multiple inert gas elimination technique data showed that animals treated with PFX vapor demonstrated a higher VA/Q heterogeneity than the control animals (P &lt; 0.05, repeated-measures analysis of covariance). Microsphere data showed a redistribution of Qrel attributable to oleic acid injury. Qrel shifted from areas that were initially high-flow to areas that were initially low-flow, with no difference in redistribution between the groups. After established injury, Qrel was redistributed to the nondependent lung areas in control animals, whereas Qrel distribution did not change in treatment animals. Conclusion In oleic acid lung injury, treatment with PFX vapor improves gas exchange by increasing VA/Q heterogeneity in the whole lung without a significant change in gravitational gradient.

The purpose of the study is to examine the pedagogical usability of interactive e-learning materials for foreign language practice. It is based upon two studies of the expected between-group and within-group differences among participants in the educational process. The sample consists of two groups – lecturers and students, a total of 100 participants, each evaluating four materials specifically prepared for this study. Two consecutive repeated measures ANOVA were conducted in which the gender/age, the position of the participants in the educational process, and usability dimensions were the independent variables. Results indicated that all independent variables and their interactions have a significant effects on the evaluations of the pedagogical usability. Women tend to assign higher values than men. Аge groups generally differ in their evaluations, although there is a tendency to give similar ratings for the individual dimensions of pedagogical usability. The 31-40 years age group evaluates the materials higher while the lowest evaluations are given by the groups of 21-30 and 50+ year old participants. Students tend to rate the pedagogical usability systemically higher than the lecturers. Usability dimensions also have a significant effect on evaluations. The most prominent feature of the materials, by a great margin, is their Applicability. The findings corroborate previous research which show age and gender differences in web usability do exist. We conclude that these differences exist as much in pedagogical usability as in technical usability. Further investigations are suggested to explore more deeply the differences in the perceived pedagogical value of e-learning materials as this has implications for instructional designers, teachers and learners alike.

"The changes occurring in modern society can significantly influence individuals’ well-being, mental health and even personality traits such as narcissism and perfectionism. Since studies investigating age and gender differences in narcissism and perfectionism have produced mixed results, and the number of studies conducted in Romanian population is scarce, the main aims of this study were to investigate possible age and gender differences in narcissism, perfectionism and several mental-health indicators in a sample of healthy participants, as well as specific association patterns between these variables within each group of participants. Our sample included 465 millennials and 149 participants over 35 years of age. The results indicate that millennials reported significantly lower levels of narcissism and self-oriented perfectionism than the older generations, higher levels of depressive symptoms and lower levels of autonomy, environmental mastery, purpose in life, and self-acceptance. Female millennials reported lower levels of narcissistic traits and higher levels of socially-prescribed perfectionism, depressive symptoms, personal growth, and positive relations with others than male participants. Older females indicated significantly higher levels of depressive symptoms and loneliness than male participants. Regarding association patterns, in the group of millennial women narcissism was positively correlated with self-oriented, socially-prescribed perfectionism and subjective well-being, and negatively with loneliness, environmental mastery and purpose in life. In millennial males, we found significant positive correlations only between narcissism and subjective well-being and environmental mastery. Our findings may have important implications for the literature regarding millennials and can contribute to the interventions and prevention programs designed to improve their well-being.

This study was an attempt to replicate the findings of earlier research in which conclusions were based on a questionable interpretation of statistical results. A 2 × 2 repeated-measures analysis of covariance did not confirm, as had been previously reported, greater heart-rate recovery for 20 aerobically fit subjects as opposed to 20 unfit subjects following psychosocial stress. Two indices of electrodermal activity and State-Trait Anxiety Inventory responses also were utilized. Only the comparison between groups for Trait Anxiety was statistically significant.

ObjectiveTo assess the role of estradiol and testosterone in men with migraine.MethodsWe measured 17β-estradiol (E2) and calculated free testosterone (Tf) in serum of 17 medication-free men with migraine and 22 men without migraine group-matched for age and body mass index (BMI), targeted at 20 to 28 kg/m2. Blood was sampled on a single, for migraineurs interictal, day at 9 am, 12 pm, 3 pm, and 6 pm. Migraineurs were subsequently measured 3 to 4 times daily until an attack occurred. Clinical androgen deficiency was assessed with the Androgen Deficiency of Ageing Men questionnaire and the Aging Males' Symptoms (AMS) scale. We analyzed interictal data (mean ± standard error) with repeated-measures analysis of covariance and longitudinal data by generalized estimated equations models.ResultsCompared to controls, men with migraine had a lower interictal Tf/E2 ratio (3.9 ± 0.4 vs 5.0 ± 0.3, p = 0.03) due to higher E2 (96.8 ± 6.1 vs 69.1 ± 5.6 pmol/L, p = 0.001) and similar Tf (357.5 ± 21.4 vs 332.6 ± 18.7 pmol/L, p = 0.35) levels. Preictal Tf levels were increased in men with migraine reporting premonitory symptoms (p = 0.03). Men with migraine more frequently reported symptoms of androgen deficiency (11 of 18 [61.1%] vs 6 of 22 [27.3%], p = 0.031), which were also more frequently severe (p = 0.006); their age- and BMI-adjusted AMS scores were higher (27.0 ± 1.2 vs 21.0 ± 1.0, p = 0.002).ConclusionsIn this study, nonobese men with migraine exhibited increased levels of the sex hormone estradiol and showed clinical evidence of relative androgen deficiency. The role of estradiol in modulating migraine susceptibility and activity in men deserves further investigations.

Abstract Implant design is one of the parameters for achieving successful primary stability. This study aims to examine the effect of a self-tapping blades implant design on initial stability in tapered implants. Polyurethane blocks of different densities were used to simulate different bone densities. The two different implant designs included one with self-tapping blades and one without self-tapping blades. Implants were placed at 3 different depths: apical third, middle third, and fully inserted at 3 different densities of polyurethane blocks. A resonance frequency (RF) analyzer was then used to measure stability of the implants. Repeated-measures analysis of variance was used to examine the effect of implant design, insertion depth, and block density on RF. Analysis of covariance was used to examine the strength of association between RF and the aforementioned factors. In both medium-density (P = .017) and high-density (P = .002) blocks, fully inserted non-self-tapping implants showed higher initial stability than self-tapping implants. No differences were noted between the 2 implant designs that were not fully inserted. The highest strength of association was with insertion depth (standardized beta [std β] = −0.60, P = .0001), followed by block density (std β = −0.15, P = .0002). Implant design showed a weak association (std β = −0.07, P = .09). In conclusion, fully inserted implants without self-tapping blades have higher initial stability than implants with self-tapping blades. However, the association strength between implant design and initial stability is less relevant than other factors, such as insertion depth and block density. Thus, if bone quality and quantity are optimal, they may compensate for design inadequacy.
