Objective: This cross-sectional, case-control study aimed to explore the psychodynamic characteristics that influenced adolescents' mental health during the COVID-19 pandemic. Methods: Personality structure impairments, psychodynamic conflicts, defense styles, and mental health issues were examined using the OPD-Structure- and Conflict-Questionnaires, the Defense Style Questionnaire, and the Patient Health Questionnaire in adolescents before (n = 288) and after (n = 451) the COVID-19 pandemic in Germany. Results: Adolescents with mental health issues exhibited greater impairments in personality structure, more immature defense styles, and higher levels of psychodynamic conflicts both before and after the pandemic onset. Comparisons between pre-pandemic and pandemic samples indicated a lower level of the conflict of taking care of oneself versus being cared for in passive mode among adolescents during the pandemic. In-depth analysis of adolescents with mental health issues from the pandemic group revealed significant associations between personality structure impairments and a maladaptive defense style with somatoform, depressive, anxiety, eating, and alcohol use disorders. Conclusion: The findings provide clinically relevant insights into the psychodynamic factors that contributed to the psychological vulnerability of adolescents during the COVID-19 pandemic. These insights can guide the development of targeted psychodynamic interventions to support adolescents' mental health in similar future crises. [ABSTRACT FROM AUTHOR]

The Omicron variants BA.1, BA.2, and BA.5 caused several waves of SARS-CoV-2 in Germany in 2022. In this comparative study, public health data on SARS-CoV-2 infections from Mecklenburg-Western Pomerania, Germany, between January and October 2022 were examined retrospectively using Pearson's chi-squared tests and Fisher's exact tests for testing for statistical significance. Compared to BA.5 infections, BA.1 and BA.2 infections affected younger individuals aged up to 19 years significantly more often, whereas BA.5 infections occurred significantly more frequently in patients between 40 and 59 years of age when compared to BA.1 and BA.2. Infections with all three variants predominantly caused flu-like symptoms; nevertheless, there were significant differences between the reported symptoms of BA.1, BA.2, and BA.5 infections. Especially, the symptoms of 'fever', 'severe feeling of sickness', 'loss of taste', and 'loss of smell' were significantly more often present in patients with BA.5 infections compared to BA.1 and BA.2 cases. Additionally, BA.2 and BA.5 cases reported significantly more often the symptoms of 'runny nose' and 'cough' than BA.1-infected cases. Our findings indicate remarkable differences in the clinical presentations among the sub-lineages, especially in BA.5 infections. Furthermore, the study demonstrates a powerful tool to link epidemiological data with genetic data in order to investigate their potential impact on public health. [ABSTRACT FROM AUTHOR]

Obesity-induced dysregulation of hypothalamic neurons is not completely eliminated by restoring body weight, therefore the most urgent task of modern precision medicine is to predict the trajectory of development of metabolic disorders associated with obesity in children. The aim of the study was to determine the level of association of single-nucleotide variants of genes that determine eating behavior – Neuronal growth regulator 1, Fat mass and obesity associated gene, Glucagon-like peptide-1 receptor, ghrelin, leptin receptor, cholecystokinin, in the development of metabolically unhealthy obesity. 252 obese children aged 6-18 years were examined. The main group (n=152) consisted of children with metabolically unhealthy obesity (MUO) according to Identification and prevention of Dietary- and Lifestyle-induced Health Effects in Children and Infants 2014 criteria. The control group (n=100) consisted of children with metabolically healthy obesity (MHO). All children underwent a general clinical, immunobiochemical examination at the Synevo laboratory (Ukraine). Whole-genome sequencing (CeGat, Germany) was performed in 31 children of the primary and 21 children of the control group. Static analysis: variance analysis ANOVA, method of estimating data dispersion, ROC-analysis, method of testing statistical hypotheses. The level of single nucleotide variants association of anorexigenic hormone genes with MUO that exceeded the threshold accepted by 75% of the available data was, respectively, in ascending order: leptin receptor (LEPR) rs1137101 (40.38%), Glucagon-like peptide-1 receptor (GLP1R) rs1126476 (40.38%), GLP1R rs2235868 (42.31%), GLP1R rs1042044 (42.31%), LEPR rs3790435 (48.08%), cholecystokinin (CCK) rs754635 (50%), LEPR rs2186248 (55.76%), GLP1R rs6918287 (55.76%). Genotypes of the GLP1R gene, such as CC rs10305421 determine insulin resistance (F=5.6); GA/AA rs3765468 – meta-inflammation (F=5.8); AA rs6918287 – basal hyperglycemia (F=6.3) and triglyceridemia (F=51.3), p<0.05. Single-nucleotide variants of the gene GLP1R rs6918287, LEPR rs2186248, CCK rs754635 of the anorexic hormones that control eating behavior are highly associated with the presence of metabolically unhealthy obesity in children.

Purpose: This study assessed the effects of the COVID-19 pandemic restrictions/lockdowns on physical activity levels, bodymass, quadriceps strength, and gait biomechanics over 18 months. Methods: Ten healthy men were assessed at baseline (~14 wk before first lockdown) and 17.9 ± 0.3 months later (<1 wk after second lockdown). At both times, physical activity levels, body mass, and quadriceps strength were acquired using the International Physical Activity Questionnaire, a force plate, and a dynamometer, respectively. Gait data were also acquired using a motion capture system and force plates during self-paced walking, from which spatiotemporal parameters, knee angles, and externalmoments were computed. Baseline and follow-upmeasurements were compared using two-tailed paired t-tests (a = 0.05). Results: At follow-up, participants spent less time doing vigorous physical activity (Δ = -76 ± 157 min·wk-1, P = 0.048), exhibited a tendency toward increased sedentary time (Δ = +120 ± 162 min·d-1, P = 0.056), weighedmore (Δ = +2.5 ± 2.8 kg, P = 0.021), and showed a trend toward reduced quadriceps strength (Δ = -0.29 ± 0.45 (N·m)·kg-1, P = 0.071) compared with baseline. At follow-up, participants walked slower (Δ = -0.09 ± 0.07 m·s-1, P = 0.005), had greater knee flexion angles at heel strike (Δ = +2.2° ± 1.8°, P = 0.004) and during late stance (Δ = +2.2° ± 1.8°, P = 0.004), had reduced knee extension moments (Δ = -0.09 ± 0.09 (N·m)·kg-1, P = 0.012) and knee internal rotationmoments (Δ = -0.02 ± 0.02 (N·m)·kg-1, P = 0.012) during late stance. Conclusions: Healthymen exhibited reduced physical activity levels, increased body weight, a tendency toward reduced quadriceps strength, and altered gait biomechanics over the initial 18months of the COVID-19 pandemic--alterations that could have far-reaching health consequences.

Introduction: Myeloid leukaemic blasts can be converted into leukaemia-derived dendritic cells (DCleu), characterised by the simultaneous expression of dendritic- and leukaemia-associated antigens, which have the competence to prime and enhance (leukaemia-specific) immune responses with the whole leukaemic antigen repertoire. To display and further specify dendritic cell (DC)- and DCleu-mediated immune responses, we analysed the interferon gamma (IFNy) secretion of innate and adaptive immune cells. Methods: DC/DCleu were generated from leukaemic whole blood (WB) with (blast)modulatory Kit-I (granulocyte-macrophage colony-stimulating factor [GM-CSF] + Picibanil [OK-432]) and Kit-M (GM-CSF + prostaglandin E1) and were used to stimulate T cell-enriched immunoreactive cells. Initiated anti-leukaemic cytotoxicity was investigated with a cytotoxicity fluorolysis assay. Initiated IFNy secretion of T, NK, CIK, and iNKT cells was investigated with a cytokine secretion assay (CSA). IFNy positivity was additionally evaluated with an intracellular cytokine assay (ICA). Recent activation of leukaemia-specific cells was verified through addition of leukaemia-associated antigens (LAA; WT-1 and Prame) Results: We found Kit-I and Kit-M competent to generate mature DC and DCleu from leukaemic WB without induction of blast proliferation. Stimulation of immunoreactive cells with DC/DCleu regularly resulted in an increased anti-leukaemic cytotoxicity and increased IFNy secretion of T, NK, and CIK cells, pointing to the significant role of DC/DCleu in leukaemia-specific alongside anti-leukaemic reactions. Interestingly, an addition of LAA did not further increase IFNy secretion, suggesting an efficient activation of leukaemia-specific cells. Here, both the CSA and ICA yielded comparable frequencies of IFNy-positive cells. Remarkably, the anti-leukaemic cytotoxicity positively correlated with the IFNy secretion in TCD3+, TCD4+, TCD8+, and NKCD56+ cells. Conclusion: Ultimately, the IFNy secretion of innate and adaptive immune cells appeared to be a suitable parameter to assess and monitor the efficacy of in vitro and potentially in vivo acute myeloid leukaemia immunotherapy. The CSA in this regard proved to be a convenient and reproducible technique to detect and phenotypically characterise IFNy-secreting cells. In respect to our studies on DC-based immunomodulation, we were able to display the potential of DC/DCleu to induce or improve leukaemia-specific and anti-leukaemic activity. [ABSTRACT FROM AUTHOR]

Introduction: The COVID-19 pandemic caught the health care systems of all countries unprepared. For the further education of healthcare personnel in the Republic of Kosovo, it became necessary to implement a concept for practical training in hygienic working. A video-conference–based educational concept to bridge the physical distance between Germany and Kosovo enabled the rapid, theoretical and practical transfer of knowledge. Methods: Current evidence on COVID-19 and Standard Operation Procedures (SOP) were researched. Healthcare staff in Pristina were advised and trained in ten online sessions on hygienic working under pandemic conditions via the "Logitech Rally for DFNconf" video conferencing system. The seminars were interpreted consecutively (Albanian). The Situational Judgement Test (HygiKo-SJT) should describe changes in participants' hygiene knowledge. Results: A total of 25 people were trained in hygiene-related knowledge in terms of basic and specific hygiene for COVID-19. The weekly training sessions made it possible to address questions and subsequently provide practical knowledge. The HygiKo-SJT did not show a generalizable, measurable improvement in hygiene competence. Conclusion: Participants benefited from the concept and rapid implementation of a live video-conference–based seminar on "Hygiene under Pandemic Conditions". The positive experience in terms of guidance, advice and training provides the basis for implementing a dedicated "Hygiene" module in Kosovo [ABSTRACT FROM AUTHOR]

Objective: Vancomycin-resistant enterococci (VRE) are of major concern in infection control. Although broad infection control actions to check VRE have been implemented, VRE remain part of daily infection preven- tion in clinical settings. Cleaning procedures in the inanimate ward environment might play a key role in controlling VRE. In order to optimize infection control management at University Hospital Frankfurt, Germany (UHF), this study evaluates the impact of H2O2-containing cleaning wipes compared to Glucoprotamin containing wipes on VRE prevalence in intensive care wards. Methods: Retrospective analyses were conducted of the VRE prevalence on environmental materials obtained from three intensive care units (ICU) at UHF for 17 months prior to (T1) and during the 25 months after (T2) the implementation of H2O2-containing cleaning wipes from January 2016 to June 2019. The bactericidal power of the two disinfectants against VRE was compared using the 4-field test according to EN 16615 (2015). Results: At T1 and T2, n=666 and n=710 environmental samples, re- spectively, were obtained. At T1, 24.2% (n=161/666; 95% confidence interval: 21.0–27.6) and at T2, 6.9% (n=49/710; 5.1–9.0) samples were positive for VRE. In vitro disinfectant testing did not reveal any superiority of H2O2 over glucoprotamin. No effect on the VRE prevalence in patients' rectal screening materials was observed. Conclusion: Though Glucoprotamin and H2O2 were in vitro equally effective against VRE, the prevalence of VRE in ICU environment at UHF de- creased after implementation of H2O2-containig wipes. This might be due to multiple factors, of which we consider the impact of the Hawthorne effect to be the strongest. Success of infection control strategies might depend on the compliance of the persons critically in- volved. Transparent information on infection control strategies is sug- gested to increase compliance and should therefore be considered both in daily infection control and outbreak management.

Background: The oral application of vitamin B-12 may prevent its deficiency if the vitamin is absorbed via the mucosal barrier. Objectives: We studied the effect of the use of a vitamin B-12-fortified toothpaste on vitamin-status markers in vegans and assessed the efficiency of markers in the identification of vitamin-augmentation status. Design: In this 12-wk, double-blinded, randomized, placebocontrolled study, 76 vegans received either a placebo (n = 34) or vitamin B-12 (n = 42) toothpaste. Sixty-six subjects (n = 30 in the placebo arm; n = 36 in the vitamin B-12 arm) completed the intervention. Serum and plasma concentrations of vitamin B-12, holotranscobalamin, total homocysteine (tHcy), and methylmalonic acid (MMA) were measured before and after the intervention. Results: Both postintervention concentrations of vitamin B-12 and holotranscobalamin and their changes over 12 wk were higher in the vitamin B-12 group (mean ± SD change: 81 ± 135 pmol/L for vitamin B-12 and 26 ± 34 pmol/L for holotranscobalamin) than in the placebo group (227 ± 64 and 25 ± 17 pmol/L, respectively) after adjustment for baseline concentrations. Postintervention concentrations of MMA and their changes differed significantly between groups (MMA changes: 20.169 ± 0.340 compared with 20.036 ± 0.544 µmol/L in vitamin B-12 and placebo groups, respectively; P < 0.001). After adjustment for baseline tHcy, postintervention concentrations of tHcy tended to be lower (P = 0.051), and the changes in tHcy (20.7 ± 4.4 compared with 2.0 ± 5.6 µmol/L, respectively) were greater in the vitamin B-12 group than in the placebo group. Changes in vitamin B-12 markers were more prominent in vegans who reported that they had not taken vitamin B-12 supplements. Conclusion: Vitamin B-12 that is applied to the oral cavity via toothpaste enters the circulation and corrects the vitamin B-12 markers in the blood of vegans who are at higher risk of vitamin B-12 deficiency. This trial was registered at clinicaltrials.gov as NCT02679833. [ABSTRACT FROM AUTHOR]

Background: The increased cardiovascular morbidity of adults with late repair of aortic coarctation (CoA) has been well documented. In contrast, successful CoA repair in early childhood has a generally good prognosis, though adverse vascular and ventricular characteristics may be abnormal, which could increase long-term risk. This study sought to perform a comprehensive analysis of aortic elasticity and left ventricular (LV) function in patients with aortic coarctation (CoA) using cardiovascular magnetic resonance (CMR). In a subgroup of patients, we assessed structure and function of the common carotid arteries to probe for signs of systemic vascular remodeling. Methods: Fifty-one patients (median age 17.3 years), 13.9 ± 7.5 years after CoA repair, and 54 controls (median age 19.8 years) underwent CMR. We determined distensibility and pulse wave velocity (PWV) at different aortic locations. In a subgroup, common carotid artery distensibility, PWV, wall thickness and wall area were measured. LV ejection fraction (EF), volumes, and mass were measured from short axis views. Left atrial (LA) volumes and functional parameters (LAEFPassive, LAEFContractile, LAEFReservoir) were assessed from axial cine images. Results: In patients distensibility of the whole thoracic aorta was reduced (p < 0.05) while PWV was only significantly higher in the aortic arch (p < 0.01). Distensibility of the descending aorta at the level of the pulmonary arteries and PWV in the descending aorta, both correlated negatively with age at CoA repair. LA volume before atrial contraction and minimal LA volume were higher in patients (p < 0.05). LAEFPassive and LAEFReservoir were reduced (p < 0.05), and LAEFReservoir correlated negatively with aortic arch PWV (p < 0.05). LVEF, volumes and mass were not different from controls. Carotid wall thickness and PWV were higher in patients compared to controls (p < 0.05). Conclusions: Patients after CoA repair have impaired bioelastic properties of the thoracic aorta with impact on LV diastolic function. Reduced descending aortic elasticity is associated with older age at time of CoA repair. The remodeling of the common carotid artery in our sub-study suggests systemic vessel wall changes.

Background: Acceptable short-term survival rates (>90 %) of mini-implants (diameter < 3.0 mm) are only documented for mandibular overdentures. Sound data for mini-implants as strategic abutments for a better retention of partial removable dental prosthesis (PRDP) are not available. Methods/design: The purpose of this study is to test the hypothesis that immediately loaded mini-implants show more bone loss and less success than strategic mini-implants with delayed loading. In this four-center (one university hospital, three dental practices in Germany), parallel-group, controlled clinical trial, which is cluster randomized on patient level, a total of 80 partially edentulous patients with unfavourable number and distribution of remaining abutment teeth in at least one jaw will receive supplementary min-implants to stabilize their PRDP. The mini-implant are either immediately loaded after implant placement (test group) or delayed after four months (control group). Follow-up of the patients will be performed for 36 months. The primary outcome is the radiographic bone level changes at implants. The secondary outcome is the implant success as a composite variable. Tertiary outcomes include clinical, subjective (quality of life, satisfaction, chewing ability) and dental or technical complications. Discussion: Strategic implants under an existing PRDP are only documented for standard-diameter implants. Mini-implants could be a minimal invasive and low cost solution for this treatment modality.

Objectives: even though a great number of research studies have shown that high education has protective effects against dementia, some studies did not observe such a significant effect. In that respect, the aim of our study was to investigate and compare various operationalisation approaches of education and how they impact dementia risk within one sample. Methods: data were derived from the Leipzig longitudinal study of the aged (LEILA75+). Individuals aged 75 and older underwent six cognitive assessments at an interval of 1.5 years and a final follow-up 15 years after the baseline assessment. We operationalised education according to different approaches used in previous studies and analysed the impact on dementia incidence via multivariate cox regression modelling. Results: the results showed that whether education is identified as significant protector against dementia strongly depends on the operationalisation of education. Whereas the pure number of years of education showed statistically significant protective effects on dementia risk, other more complex categorical classification approaches did not. Moreover, completing >10 years of education or a tertiary level seems to be an important threshold to significantly reduce dementia risk. Conclusion: findings suggest a protective effect of more years of education on a lower dementia risk with a particular critical threshold of completing >10 years of education. Further, the findings highlight that, when examining risks and protective factors of dementia, a careful consideration of the underlying definitions and operationalisation approaches is required.

Introduction: Data evaluating mortality benefit from replacing sedentary time with physical activity are sparse. We explored reallocating time spent in sedentary behavior to physical activity of different intensities in relation to mortality risk. Methods: Women and men age 50-85 yr from the National Health and Nutrition Examination Survey 2003-2004 and 2005-2006 cycles with follow-up through December 31, 2011, were included. Sedentary time and physical activity were assessed using an ActiGraph accelerometer. Isotemporal substitution models were used to estimate the effect of replacing one activity behavior with another activity behavior for the same amount of time while holding total accelerometer wear time constant. Results: During a mean follow-up of 6.35 yr, 697 deaths from any cause occurred. Replacing 30 min of sedentary time with an equal amount of light activity was associated with 14% reduced risk of mortality (multivariable-adjusted hazard ratio (HR), 0.86; 95% confidence interval (CI), 0.83-0.90). Replacement of sedentary time with moderate to vigorous activity was related to 50% mortality risk reduction (HR, 0.50; 95% CI, 0.31-0.80). We also noted a 42% reduced risk of mortality when light physical activity was replaced by moderate to vigorous activity (HR, 0.58; 95% CI, 0.36-0.93). Conclusion: Replacing sedentary time with an equal amount of physical activity may protect against preterm mortality. Replacement of light physical activity with moderate to vigorous activity is also associated with protection from premature mortality. [ABSTRACT FROM AUTHOR]

Background: Long axis strain (LAS) has been shown to be a fast assessable parameter representing global left ventricular (LV) longitudinal function in cardiovascular magnetic resonance (CMR). However, the prognostic value of LAS in cardiomyopathies with reduced left ventricular ejection fraction (LVEF) has not been evaluated yet. Methods and results: In 146 subjects with non-ischemic dilated cardiomyopathy (NIDCM, LVEF =45 %) LAS was assessed retrospectively from standard non-contrast SSFP cine sequences by measuring the distance between the epicardial border of the left ventricular apex and the midpoint of a line connecting the origins of the mitral valve leaflets in end-systole and end-diastole. The final values were calculated according to the strain formula. The primary endpoint of the study was defined as a combination of cardiac death, heart transplantation or aborted sudden cardiac death and occurred in 24 subjects during follow-up. Patients with LAS values > -5 % showed a significant higher rate of cardiac events independent of the presence of late gadolinium enhancement (LGE). The multivariate Cox regression analysis revealed that LVEDV/BSA (HR: 1.01, p < 0.05), presence of LGE (HR: 2.51, p < 0.05) and LAS (HR: 1.28, p < 0.05) were independent predictors for cardiac events. In a sequential cox regression analysis LAS offered significant incremental information (p < 0.05) for the prediction of outcome in addition to LGE and LVEDV/BSA. Using a dichotomous three point scoring model for risk stratification, including LVEF <35 %, LAS > -10 % and the presence of LGE, patients with 3 points had a significantly higher risk for cardiac events than those with 2 or less points. Conclusion: Assessment of long axis function with LAS offers significant incremental information for the prediction of cardiac events in NIDCM and improves risk stratification beyond established CMR parameters.

Background: Studies on the association between alcohol consumption and colorectal cancer (CRC) prognosis have yielded inconsistent results. Objective: The associations of lifetime and 1-y prediagnostic alcohol consumption with relevant prognostic outcomes were evaluated in a large population-based cohort of CRC patients. Design: In 2003-2010, 3121 patients diagnosed with CRC were interviewed on sociodemographic and lifestyle factors, medication, and comorbidities. Cancer recurrence, vital status, and cause of death were documented for a median follow-up time of 4.8 y. With the use of Cox proportional hazard regression, associations between lifetime and recent alcohol consumption and overall, CRC-specific, recurrence-free, and disease-free survival were analyzed. Results: In this patient cohort with a median age of 69 y at diagnosis, lifetime abstainers showed poorer overall [adjusted HR (aHR): 1.25; 95% CI: 1.03, 1.52] and CRC-specific (aHR: 1.37; 95% CI: 1.10, 1.70) survival than lifetime light drinkers (women: >0-12 g/d; men: >0-24 g/d). Lifetime heavy drinkers showed poorer overall (aHR: 1.37; 95% CI: 1.06, 1.78) and disease-free (aHR: 1.38; 95% CI: 1.09, 1.74) survival. Alcohol abstaining in the year before diagnosis was associated with poorer overall (aHR: 1.42; 95% CI: 1.20, 1.68), CRC-specific (aHR: 1.38; 95% CI: 1.13, 1.68), and disease-free (aHR: 1.23; 95% CI: 1.05, 1.44) survival. Lifetime abstainers with nonmetastatic disease showed poorer CRC-specific (aHR: 1.48; 95% CI: 1.10, 2.00) and recurrence-free (aHR: 1.32; 95% CI: 1.02, 1.70) survival. Wine abstaining but not beer or liquor abstaining was associated with poorer survival. Associations between alcohol consumption and prognosis varied according to presence of diabetes and age. Conclusions: Prediagnostic alcohol abstaining and heavy drinking were associated with poorer survival after a CRC diagnosis than light drinking. The protective effects of light consumption might be restricted to wine, and associations might differ according to age and presence of diabetes mellitus. [ABSTRACT FROM AUTHOR]

Background: It has been hypothesized that the n-6:n-3 (ω-6: ω-3) long-chain polyunsaturated fatty acid (LCPUFA) ratio in the maternal diet during the prenatal and early postnatal phase positively affects the body composition of the offspring. However, only limited data from prospective human intervention studies with long-term follow-up are available. Objective: We assessed the long-term effects of a reduced n-6:n-3 LCPUFA ratio in the diets of pregnant and lactating women [1020 mg docosahexaenoic acid (DHA) plus 180 mg eicosapentaenoic acid (EPA)/d together with an arachidonic acid-balanced diet compared with a control diet] on the body weights and compositions of their offspring from 2 to 5 y of age with a focus on the 5-y results. Design: Participants in the randomized controlled trial received follow-up assessments with annual body-composition measurements including skinfold thickness (SFT) measurements (primary outcome), a sonographic assessment of abdominal subcutaneous and preperitoneal fat, and child growth. In addition, abdominal MRI was performed in a subgroup of 5-y-old children. For the statistical analysis, mixed models for repeated measures (MMRMs) were fit with the use of data from each visit since birth (except for MRI). Results: Maternal LCPUFA supplementation did not significantly influence the children's sum of 4 SFTs [means ± SDs at 5 y of age: intervention, 23.9 ± 4.7 mm (n = 57); control, 24.5 ± 5.0 mm (n = 55); adjusted mean difference, -0.5 (95% CI: 22.2, 1.2)], growth, or ultrasonography measures at any time point in the adjusted MMRM model (all P values < 0.05). Results were consistent with abdominal MRI measurements (n = 44) at 5 y of age, which showed no significant differences in subcutaneous and visceral adipose tissue volumes and ratios. Conclusion: The current study provides no evidence that a dietary reduction of the n-6:n-3 LCPUFA ratio in the maternal diet during pregnancy and lactation is a useful early preventive strategy against obesity at preschool age. This trial was registered at clinicaltrials. gov as NCT00362089. [ABSTRACT FROM AUTHOR]

Background: Little is known about the prognostic impact of red and processed meat intake or about changes in consumption after a diagnosis of colorectal cancer (CRC). Objectives: We investigated associations of baseline red and processed meat with survival outcomes and explored changes in intake among CRC survivors 5 y after diagnosis. Design: A total of 3122 patients diagnosed with CRC between 2003 and 2010 were followed for a median of 4.8 y [DACHS (Darmkrebs: Chancen der Verhütung durch Screening) study]. Patients provided information on diet and other factors in standardized questionnaires at baseline and at the 5-y follow-up. Cox proportional hazards regression models were used to estimate HRs and 95% CIs. Results: Among patients with stage I-III CRC, baseline red and processed meat intake was not associated with overall (>1 time/d compared with <1 time/d; HR: 0.85; 95% CI: 0.67, 1.09), CRC-specific (HR: 0.83; 95% CI: 0.61, 1.14), cardiovascular disease-specific (HR: 0.92; 95% CI: 0.51, 1.68), non-CRC-specific (HR: 0.88; 95% CI: 0.59, 1.30), and recurrence-free (HR: 1.03; 95% CI: 0.80, 1.33) survival; results among stage IV patients were comparable. An association with worse overall survival was found among patients with Kirsten rat sarcoma viral oncogene homolog (KRAS)-mutated CRC (HR: 1.99; 95% CI: 1.10, 3.56) but not with microsatellite instability or CpG island methylator phenotype (CIMP) positivity. A much lower proportion of survivors reported daily consumption of red and processed meat at the 5-y follow-up than at baseline (concordance rate: 39%; κ-value: 0.10; 95% CI: 0.07, 0.13). Conclusions: Our findings suggest that baseline red and processed meat intake is not associated with poorer survival among patients with CRC. The potential interaction with KRAS mutation status warrants further evaluation. Major changes in consumption measured at the 5-y follow-up may have had an impact on our survival estimates.

Integrating the perspectives of psychological contract and sex differences, this study examines how organizational decision to reduce labour costs influences employees' perceived psychological contract breach and their commitment to their organizations. Using two experiments, we found three-way interaction effects among the decision to reduce labour costs, employee sex, and the managerial control over the decision. The decision of labour costs reduction leads to stronger feelings of psychological contract breach for females when the decision is in low than in high levels of managerial control, but the same decision leads to stronger psychological contract breach for males when the decision is in high than in low levels of managerial control. Furthermore, the indirect effect of labour costs reduction on employees' organizational commitment through psychological contract breach is also contingent upon the interaction between employee sex and managerial control. Our findings expand the literature of psychological contract and shed light on timely practical issues of management's decisions regarding labour costs reduction. Practitioner points Labour costs reductions in economic downturns lead to different responses from employees, and managers are advised to plan their actions bearing in mind such differences., Management in crisis or difficulties calls for more delicate considerations of employees' psychological feelings towards the organization., Nuanced empirical evidence informs us about the different needs and responses of a diverse group of employees and how their responses contradict.

Although playing a crucial role for the prevention of long-term health impairment, interventions aiming at the improvement of employees' recovery processes are still scarce. In this study, we therefore investigated the effectiveness of a low-dose mindfulness intervention for recovery from work. In addition, differential responding to the treatment in terms of treatment-by-baseline interactions was studied. A sample of 140 employees participated in a randomized field experiment with a self-training and a wait-list control group. Three central recovery processes (psychological detachment, sleep quality, and sleep duration) were assessed with event-sampling methodology involving daily measurements over 10 workdays. Growth curve analyses revealed intervention effects on sleep quality and sleep duration. No effects were found for psychological detachment after work and for the proposed treatment-by-baseline interactions. Our findings are discussed in the context of occupational health promotion in general and mindfulness-based interventions in specific. Practitioner points Although daily recovery from the demands of work has been shown to be vital for employee well-being and performance, research on how workplace interventions can help improve recovery is still scarce., This study investigated the effectiveness of a brief, economic mindfulness intervention on processes that are vital for recovery - psychological detachment, sleep quality, and sleep duration., Findings revealed positive effects of the intervention on sleep quality and duration, but not on psychological detachment.

Background: Continuity of care is important for outcomes and patient satisfaction and includes additional considerations in the context of cross-border health care. Although this has been discussed in research and was picked up in the recently transposed Directive on patients' rights (2011/24/EU), there is limited evidence about related issues actually encountered by patients crossing borders. Methods: An anonymous postal survey was carried out by the Techniker Krankenkasse, one of the largest sickness funds in Germany. The questionnaire was sent to 45 189 individuals who had received treatment in EU/EEA countries and included items on relational, management and informational continuity. Results: The survey had a response rate of 41% (n = 17 543). Of those respondents who had travelled for care (n = 3307), ∼19% (n = 570) did so due to a relationship of trust with a given provider. Only 8% of all respondents required emergency follow-up services due to complications, the majority of which was obtained back in Germany. Twelve percentage of those who were prescribed medication abroad (n = 4208) reported problems, spanning unknown products, dispensation and reimbursement. Information exchange between providers across borders was rare and largely carried out by the patients themselves. Conclusions: Although relational continuity may be important to specific groups of patients travelling for care, it is primarily informational continuity and its interrelation with management continuity that need to be addressed in the cross-border context. Information exchange should be endorsed at European level. Additional focus is required on informing patients about documentation rights and requirements and providing health records that are comprehensive and comprehensible. [ABSTRACT FROM AUTHOR]

Background: Whole-body magnetic resonance imaging (MRI) is the gold standard for the assessment of skeletal muscle (SM) and adipose tissue volumes. It is unclear whether single-slice estimates can replace whole-body data. Objective: We evaluated the accuracy of the best single lumbar and midthigh MRI slice to assess whole-body SM, visceral adipose tissue (VAT), and subcutaneous adipose tissue (SAT). Design: Whole-body MRI was performed in 142 healthy adults aged 19-65 y [mean ± SD age: 37.0 ± 11.8 y; BMI (in kg/m²): 25.3 ± 5.9]. Single slices were taken at lumbar vertebrae L1-L5 plus intervertebral discs and the thigh (midthigh, 10 cm distally from the midthigh, and 10 cm proximally from the midthigh). The value of single-slice areas was also tested in a longitudinal study on 48 healthy volunteers during weight loss (8.2 ± 5.2 kg). Results: Cross-sectionally, all SM and adipose tissue single-slice areas correlated with total tissue volumes (P < 0.01). Because of the close associations between L3 areas and corresponding tissue volumes (r = 0.832-0.986, P < 0.01), this location was identified as the reference to estimate SM and adipose tissue in both sexes. SM, SAT, and VAT areas at L3 explained most of the variance of total tissue volumes (69-97%, with SEs of estimation of 1.96 and 2.03 L for SM, 0.23 and 0.61 L for VAT, and 4.44 and 2.47 L for SAT for men and women, respectively. There was no major effect on the explained variance compared with that for optimal slices. For SM, the optimal slice area was shown at midthigh. With weight-loss changes in total SM, VAT, and SAT, volumes were significantly different from those at baseline (SM changes: 22.8 ± 2.9 L; VAT changes: 20.7 ± 1.0 L; SAT changes: 25.1 ± 6.0 L). The area at L3 reflected changes in total VAT and SAT. To assess changes in total SM volumes, areas at midthigh showed the best evidence. Conclusion: In both sexes, a single MRI scan at the level of L3 is the best compromise site to assess total tissue volumes of SM, VAT, and SAT. By contrast, L3 does not predict changes in tissue components. This trial was registered at clinicaltrials.gov as NCT01737034. [ABSTRACT FROM AUTHOR]

Background: An association between desaturase activity and risk of type 2 diabetes (T2D) has been found in epidemiologic studies, but little is known about potential mediators of this association. Objective: We aimed to investigate the potential role of diabetes-related biomarkers as mediators of the association between estimated Δ5 desaturase (D5D), D6 desaturase (D6D), and stearoyl-CoA desaturase (SCD) activity and T2D risk. Design: We analyzed a case-cohort study (subcohort: n = 1533; verified incident T2D cases: n = 400), nested within the European Prospective Investigation into Cancer and Nutrition-Potsdam Study involving 27,548 middle-aged participants. We evaluated the impact of adjustment for several T2D-related biomarkers reflecting liver fat accumulation [reflected by g-glutamyltransferase (GGT), alanine transaminase (ALT), fetuin-A, and the algorithm-based fatty liver index (FLI)], dyslipidemia (high-density lipoprotein cholesterol, triglycerides), inflammation [C-reactive protein (CRP)], and adipo-nectin on the association between D5D, D6D, and SCD activity, estimated with fatty acid product-to-precursor ratios derived from erythrocyte membrane proportions, and T2D risk. Results: Estimated D5D activity was inversely associated with T2D risk, whereas D6D and SCD activities were positively associated with risk of T2D [HRs (95% CIs) (highest vs. lowest tertile): 0.51 (0.36, 0.73), 1.68 (1.18, 2.39), and 1.82 (1.29, 2.58), respectively]. The association between estimated D5D, D6D, and SCD activities and risk of T2D was statistically significantly and markedly attenuated after adjustment for the FLI and, to a lesser extent, after adjustment for triglycerides, whereas adjustment for other desaturase-associated biomarkers (CRP, fetuin-A, ALT, and GGT) did not lead to appreciable attenuations. Conclusions: Liver fat accumulation, as reflected by the FLI, and dyslipidemia, as reflected by triglycerides, may partly explain the association between estimated D5D, D6D, and SCD activity and T2D risk.

Background: Considering the suggested link between vitamin D insufficiency and several chronic diseases, attention should be given to approaches for improving vitamin D status. Elderly subjects are regarded as a high-risk group for developing an insufficient vitamin D status. Socioeconomic, dietary, lifestyle and environmental factors are considered as influencing factors, whereupon sex differences in predictors of vitamin D status are rarely investigated. The purpose of this study is to identify the main predictors of serum 25-hydroxyvitamin D3 [25(OH)D3] concentrations in elderly subjects by taking into account potential sex differences. Methods: This is a cross-sectional study in 162 independently living German elderly aged 66 to 96 years. Serum 25(OH)D3 concentrations were assessed by an electrochemiluminescence immunoassay. Multiple regression analyses were performed to identify predictors of 25(OH)D3 concentrations stratified by sex. Results: Median 25(OH)D3 concentration was 64 nmol/L and none of the subjects had 25(OH)D3 concentrations < 25 nmol/L. In women, intact parathyroid hormone (iPTH) (β = -0.323), % total body fat (β = -0.208), time spent outdoors (β = 0.328), month of blood sampling (β = 0.229) and intake of vitamin D supplements (β = 0.172) were the predominant predictors of 25(OH)D3, whereas in men, iPTH (β = -0.254), smoking (β = -0.282), physical activity (β = 0.336) and monthly household net income (β = 0.302) predicted 25 (OH)D3 concentrations. The final regression models accounted for 30% and 32% of the variance in 25(OH)D3 concentrations in women and men, respectively. Conclusion: The findings indicate that 25(OH)D3 concentrations are influenced by body composition, month of blood sampling, economic factors, lifestyle, supplement intake and iPTH, but may not be associated with age, sex, dietary factors, kidney function and presence of selected chronic diseases in community-dwelling elderly. Furthermore, our results provide evidence for sex-specific determinants of the vitamin D status, which ought to be considered for preventive strategies. [ABSTRACT FROM AUTHOR]

Background: Plant sterols (PSs) lower LDL cholesterol, an established risk factor for coronary artery disease (CAD). No direct evidence is available supporting a reduced risk of CAD for foods with added PSs. Endothelial dysfunction is seen as an early indicator of atherosclerotic damage. Objectives: This study was primarily designed to investigate the effect of a low-fat spread with added PSs on brachial artery endothelial function as measured by flow-mediated dilation (FMD). Second, effects on arterial stiffness, blood pressure, serum lipids, and plasma PS concentrations were investigated. We hypothesized that PSs would not worsen FMD but would rather modestly improve FMD. Design: This study had a double-blind, randomized, placebo-controlled, parallel design. After a 4-wk run-in period, 240 hypercholesterolemic but otherwise healthy men and women consumed 20 g/d of low-fat spread without (control) or with added PSs (3 g/d) during 12 wk. Pre- and postintervention, vascular function measurements and blood sampling were performed. Results: In total, 232 participants completed the study period. For the primary endpoint FMD, 199 participants were included in the statistical analysis. PS intake did not affect FMD (+0.01 percentage points; 95% CI: —0.73, 0.75) compared with control. Measures of arterial stiffness (pulse wave velocity and augmentation index) and blood pressure were also not significantly changed compared with control. After PS intervention, LDL cholesterol significantly decreased on average by 0.26 µmol/L (95% CI: —0.40, —0.12) or 6.7% compared with control. Plasma sitosterol and campesterol concentrations significantly increased in the PS group up to on average 11.5 µmol/L and 13.9 µmol/L (expressed as geometric means), respectively. Conclusions: The intake of a low-fat spread with added PSs neither improved nor worsened FMD or other vascular function markers in hypercholesterolemic men and women. As expected, serum LDL cholesterol decreased, whereas plasma PSs increased after PS intake. This study was registered at clinicaltrials.gov as NCT01803178. Am J Clin Nutr 2015;101:733-41.

Background: Visceral (VAT) and subcutaneous abdominal (SAAT) and trunk (STRAT) adipose tissue (AT) have been suggested to be differentially influenced by diet. Objective: We investigated whether and to what extent usual patterns of nutrient intake are associated with VAT, SAAT, and STRAT compared with nondietary predictors in northern German adults (n = 583). Design: AT volumes were quantified by magnetic resonance imaging. Nutrient intake was estimated by a 112-item food-frequency questionnaire linked to the German Food Code and Nutrient Database. Exploratory nutrient patterns were derived by principal components analysis (PCA) and partial least-squares regression (PLS) of 87 nutrients. Cross-sectional associations between nutrient patterns, single nutrients, or total energy intake and AT compartments were analyzed by multiple linear regression. Results: Next to sex and age, respectively, which were important nondietary predictors and accounted for more of the variation in VAT (~13% and ~4%) than in SAAT or STRAT (both 4-7% and <1%), variation in VAT (16.8% or 17.6%) was explained to a greater extent by 9 or 2 nutrient patterns derived by principal components analysis or partial least-squares regression, respectively, than was variation in SAAT (10.6% or 8.2%) or STRAT (11.5% or 8.6%). Whereas VAT (16.6%) was primarily explained by nutrient quality, SAAT (6.9%) and STRAT (7.4%) were mainly explained by total energy intake. VATwas positively associated with nutrients characteristic of animal (except for dairy) products, including arachidonic acid (standardized β 0.25; 95% CI: 0.15, 0.34; P < 0.0001), but negatively with dietary fiber, including polypentoses (standardized β: -0.17; 95% CI: -0.24, -0.09; P < 0.0001), and nutrients found in milk. The direction and strength of many associations, however, depended strongly on sex and adjustment for BMI. Conclusion: VAT may be particularly associated with sex-specific interplays of nutrients found in animal products and fiber, whereas SAAT and STRAT are associated with total energy intake.

Objective To correlate the amount and types of pain medications prescribed to CRPS patients, using the Medication Quantification Scale, and patients' subjective pain levels. Design An international, multisite, retrospective review. Setting University medical centers in the United States, Israel, Germany, and the Netherlands. Subjects/Methods A total of 89 subjects were enrolled from four different countries: 27 from the United States, 20 Germany, 18 Netherlands, and 24 Israel. The main outcome measures used were the Medication Quantification Scale III and numerical analog pain scale. Results There was no statistically significant correlation noted between the medication quantification scale and the visual analog scale for any site except for a moderate positive correlation at German sites. The medication quantification scale mean differences between the United States and Germany, the Netherlands, and Israel were 9.793 ( P < 0.002), 10.389 ( P < 0.001), and 4.984 ( P = 0.303), respectively. Conclusions There appears to be only a weak correlation between amount of pain medication prescribed and patients' reported subjective pain intensity within this limited patient population. The Medication Quantification Scale is a viable tool for the analysis of pharmaceutical treatment of CRPS patients and would be useful in further prospective studies of pain medication prescription practices in the CRPS population worldwide.

Background: Single parathyroid adenoma is the main cause of primary hyperparathyroidism (PHPT), with surgery remaining the gold standard for its treatment. The ability to preoperatively predict the parathyroid adenoma size and could facilitate the decision about the extent of surgical exploration. It is reasonable to hypothesize that the perioperative levels of PHPT-related variables (i.e. calcium, parathormone, phosphate) may predict the adenoma weight or/and demonstrate whether the adenoma is successfully removed or not. Aim of this study is to explore the relationship between perioperative biochemical values and adenoma weight. Secondarily, we investigated the relationship between adenoma weight and uni-/bilateral neck exploration.Methods: Retrospective study of all patients undergone surgery for primary hyperparathyroidism due to single adenoma in a tertiary university hospital in Germany during a 6-year period. Following variables were analyzed: preoperative serum calcium, phosphorus and parathormone, intraoperative parathormone before and after adenoma excision, intraoperative PTH decrease, postoperative serum calcium and parathormone (PTHpostop-pg/ml), calcium and PTH decrease. Bivariate correlations were calculated by the Spearman's correlation test at the 95% significance level.Results: A total of 339 patients were included in the study. The median age of the patients was 60 years (range 21-90) and 77% were females. The median adenoma weight was 1 g (range 0.1-11). Adenoma weight correlated strong with maximum adenoma diameter (r = 0.72, p < 0.05), moderate with preoperative parathormone (r = 0.44) and parathormone decrease (r = 0.27), whereas there was no correlation with the intraoperative PTH decrease (r = 0.02). There was also a borderline (moderate to weak) correlation with pre- and postoperative calcium levels (r = 0.21 and r = 0.23 respectively) and a negative borderline correlation with phosphorus (r = - 0.21). Patients who required bilateral neck exploration, had significantly lighter adenomas (median weight 0.8 g vs 1.1 g, p = 0.005).Conclusions: We conclude that preoperative PTH levels may only serve as an approximate guide to adenoma weight, as direct preoperative prediction is not possible. Serum calcium levels, PTH and calcium decrease correlate only weak with adenoma weight. Patients who require bilateral neck exploration, have significantly (20-25%) lighter adenomas.

The role of this study was to determine which changes people think they need to make in their home in response to getting older. At an advanced age, the likelihood of different limitations, such as vision impairment, hearing impairment, or physical inability, are increased. At present, when faced with such limitations, tenants are often forced to leave their long-term living spaces, as these spaces cannot serve their "new" individual needs. This transition from the privacy of their home to a new environment is often a painful change. They must leave a well-known environment, as their homes cannot be adapted to their new needs. The aim of this paper is to develop a comprehensive approach for the design of an exterior and interior space which can serve people through all stages of life, particularly in terms of mobility. This means that, even if an unexpected situation incurs changes in an individual's movement abilities or physiological limitations not only by natural aging, but also according to accidents or disabilities their living space can be adapted to the given conditions. The results of a survey conducted in Germany and Slovakia are presented. In the survey, respondents expressed their opinion on what they considered important in creating an adaptive environment, considering various life changes. The results of the survey are statistically processed and analyzed by the ANOVA method, a form of statistical hypothesis testing. The results are processed graphically and presented in tables, along with explanations. The results could be of an interest to the architects and designers of such environments. Based on the results of the survey, studies of possible modifications of flats and houses are developed. These results are analyzed in terms of three age groups: people aged below 35, those aged 35–50, and those aged over 50. People under 35 are considered to be quite young, with different views on life and on the environment. Their priorities typically differ from those of people around 50. People aged 50 more; have been under medical treatment for a consistent amount of time. This group of people is still active; however, they experience different design requirements for their potential home. • Post describes what changes can be made in the home if the health status changes. • Emphasis is on designing living space for all phases of life, especially mobility. • Survey in Germany and Slovakia expresses different opinions on the houses adaptability. • Statistical analysis of the three age groups shows different priorities and common views. • Results show architects and designers what is important in creating an environment.
