RESUMO

AIM OF THE STUDY: Taking into consideration and addressing patients' psychosocial problems is one of the characteristics of good clinical practice; this applies to IBD-patients as well. Since 2014, such patients have been offered an online questionnaire-based problem assessment linked to care recommendations. The primary aim of our data analysis was to carry out a comparative description of socio-demographic and disease-related characteristics of users of the free service. METHODOLOGY: For a retrospective data analysis, the online sample (OG) comprising 2156 CD and UC patients was compared with 852 individuals who participated in 2 IBD health services research studies (CG). Besides descriptive statistics, regression and covariance analyses were carried out. RESULTS: The OG differed from CG in a highly significant and partly clinically relevant way. One in 3 of the OG was younger than 30 years of age (CG: 19%); 45% had completed high school (CG: 36%). In the OG, fewer were in disease remission (OG 34%; CG 59%). Even controlling for these differences, the OG reported more often greater burden in 12 of 17 psychosocial problem areas and expressed a greater need for information on 5 of 9 disease-related topic areas. CONCLUSION: The internet-based assessment of psychosocial problems is used primarily by younger, better educated, and physically as well as psychosocially more burdened IBD patients with comparatively high information needs. The assessment may help them to actively participate in their care. Our data sheds further light on the peculiarities of internet-based study groups.

RESUMO

BACKGROUND: The question of whether there is daytime time variation in diet-induced thermogenesis (DIT) has not been clearly answered. Moreover, it is unclear whether a potential diurnal variation in DIT is preserved during hypocaloric nutrition. OBJECTIVE: We hypothesized that DIT varies depending on the time of day and explored whether this physiological regulation is preserved after low-calorie compared with high-calorie intake. DESIGN: Under blinded conditions, 16 normal-weight men twice underwent a 3-day in-laboratory, randomized, crossover study. Volunteers consumed a predetermined low-calorie breakfast (11% of individual daily kilocalorie requirement) and high-calorie dinner (69%) in one condition and vice versa in the other. DIT was measured by indirect calorimetry, parameters of glucose metabolism were determined, and hunger and appetite for sweets were rated on a scale. RESULTS: Identical calorie consumption led to a 2.5-times higher DIT increase in the morning than in the evening after high-calorie and low-calorie meals (P < .001). The food-induced increase of blood glucose and insulin concentrations was diminished after breakfast compared with dinner (P < .001). Low-calorie breakfast increased feelings of hunger (P < .001), specifically appetite for sweets (P = .007), in the course of the day. CONCLUSIONS: DIT is clearly higher in the morning than in the evening, irrespective of the consumed calorie amount; that is, this physiological rhythmicity is preserved during hypocaloric nutrition. Extensive breakfasting should therefore be preferred over large dinner meals to prevent obesity and high blood glucose peaks even under conditions of a hypocaloric diet.

RESUMO

BACKGROUND: Obstructive sleep apnoea (OSA) is common in children with Down syndrome (DS), yet difficult to treat. As muscular hypotonia of the upper airway may cause OSA and is also common in DS, we tested whether intense myofunctional therapy improves OSA in children with DS. PATIENTS AND METHODS: Forty-two children underwent cardiorespiratory sleep studies immediately before and after a 1-week intensive training camp consisting of three daily 45 min sessions of myofunctional exercises according to Padovan. Primary outcome was the mixed-obstructive-apnoea/hypopnoea index (MOAHI), secondary outcomes the ≤3% oxygen desaturation index (DI3), the ≤90% desaturation index (DI90) and the lowest pulse oximeter saturation (SpO2nadir). RESULTS: Eighteen recordings had ≥3 hours of artefact-free recording in both the pretreatment and post-treatment sleep study and were therefore included in the analysis. Mean age was 6.3 years (SD 2.5); 83% had OSA prior to intervention. Mean MOAHI was 6.4 (SD 8.6) before and 6.4 (SD 10.8) after the intervention (p>0.05); the DI3 and SpO2nadir also did not change. Only the DI90 decreased significantly from 2.7 (SD 4.5) to 2.1 (SD 3.7) (p<0.05). CONCLUSION: The 1-week intense myofunctional training camp evaluated here in children with DS had only a marginal effect on OSA. Whether a longer follow-up period or duration of intervention would yield stronger effects remains to be determined.

RESUMO

BACKGROUND: The dorsolateral prefrontal cortex (DLPFC) plays an important role in appetite and food intake regulation. OBJECTIVE: Because previous data revealed that transcranial direct current stimulation (tDCS) of the DLPFC reduces food cravings, we hypothesized that repetitive electric stimulation of the right DLPFC would lower food intake behavior in humans. DESIGN: In a single-blind, code-based, placebo-controlled, counterbalanced, randomized crossover experiment, 14 healthy young men with body mass index (in kg/m(2)) from 20 to 25 were examined during 8 d of daily tDCS or a sham stimulation. After tDCS or sham stimulation on the first and the last day of both experimental conditions, participants consumed food ad libitum from a standardized test buffet. RESULTS: One week of daily anodal tDCS reduced overall caloric intake by 14% in comparison with sham stimulation. Moreover, repetitive tDCS diminished self-reported appetite scores. CONCLUSION: Our study implies that the application of anodal direct currents to the right DLPFC represents a promising option for reducing both caloric intake and appetite in humans. This trial was registered at the German Clinical Trials Register (www.germanctr.de) as DRKS00005811.

RESUMO

Shortened nocturnal sleep impairs morning glucose tolerance. The underlying mechanism of this effect is supposed to involve a reduced fraction of slow wave sleep (SWS). However, it remains unanswered if impaired glucose tolerance occurs due to specific SWS reduction or a general disturbance of sleep. Sixteen healthy men participated in three experimental conditions in a crossover design: SWS suppression, rapid eye movement (REM)-sleep disturbance, and regular sleep. Selective sleep stage disturbance was performed by means of an acoustic tone (532Hz) with gradually rising sound intensity. Blood concentrations of glucoregulatory parameters were measured upon an oral glucose tolerance test the next morning. Our data show that morning plasma glucose and serum insulin responses were significantly increased after selective SWS suppression. Moreover, SWS suppression reduced postprandial insulin sensitivity up to 20%, as determined by Matsuda Index. Contrastingly, disturbed REM-sleep did not affect glucose homeostasis. We conclude that specifically SWS reduction is critically involved in the impairment of glucose tolerance associated with disturbed sleep. Therefore, glucose metabolism in subjects predisposed to reduced SWS (e.g. depression, aging, obstructive sleep apnea, pharmacological treatment) should be thoroughly monitored.

RESUMO

Sleep enhances memory consolidation. Bearing in mind that food intake produces many metabolic signals that can influence memory processing in humans (e.g., insulin), the present study addressed the question as to whether the enhancing effect of sleep on memory consolidation is affected by the amount of energy consumed during the preceding daytime. Compared to sleep, nocturnal wakefulness has been shown to impair memory consolidation in humans. Thus, a second question was to examine whether the impaired memory consolidation associated with sleep deprivation (SD) could be compensated by increased daytime energy consumption. To these aims, 14 healthy normal-weight men learned a finger tapping sequence (procedural memory) and a list of semantically associated word pairs (declarative memory). After the learning period, standardized meals were administered, equaling either ∼50% or ∼150% of the estimated daily energy expenditure. In the morning, after sleep or wakefulness, memory consolidation was tested. Plasma glucose was measured both before learning and retrieval. Polysomnographic sleep recordings were performed by electroencephalography (EEG). Independent of energy intake, subjects recalled significantly more word pairs after sleep than they did after SD. When subjects stayed awake and received an energy oversupply, the number of correctly recalled finger sequences was equal to those seen after sleep. Plasma glucose did not differ among conditions, and sleep time in the sleep conditions was not influenced by the energy intake interventions. These data indicate that the daytime energy intake level affects neither sleep's capacity to boost the consolidation of declarative and procedural memories, nor sleep's quality. However, high energy intake was followed by an improved procedural but not declarative memory consolidation under conditions of SD. This suggests that the formation of procedural memory is not only triggered by sleep but is also sensitive to the fluctuations in the energy state of the body.

RESUMO

Individuals from racial/ethnic minority backgrounds and women have not been proportionately represented in AIDS clinical trials (ACTs). There have been few intervention efforts to eliminate this health disparity. This paper reports on a brief behavioral intervention to increase rates of screening for ACTs in these groups. The study was exploratory and used a single-group pre/posttest design. A total of 580 persons living with HIV/AIDS (PLHA) were recruited (39% female; 56% African-American, 32% Latino/Hispanic). The intervention was efficacious: 25% attended screening. We identified the primary junctures where PLHA are lost in the screening process. Both group intervention sessions and an individual contact were associated with screening. Findings provide preliminary support for the intervention's efficacy and the utility of combining group and individual intervention formats. Interventions of greater duration and intensity, and which address multiple levels of influence (e.g., social, structural), may be needed to increase screening rates further.
