RESUMO

BACKGROUND: Video consultation is a possibility for physician-patient communication independent of the location; however, only limited information is available for the possibility of sole use since 2018. METHODS: After the implementation of video consultation (Viomedi) in lipid consultations at the Medical University Mainz, the patients in the first quarter of 2022 were assessed depending on the possibility, suitability and readiness to participate. Included were patients under lipid management and long COVID patients. After treatment an online survey was carried out on the utilization and appraisal. RESULTS: Of the 134 patients 29.1% were inclusively treated (3 refusals). All subjects (16 replies) reported having managed (very) well. Advantages were seen in counselling and follow-up. Problems were feared with respect to technology and possible disorders. Data protection aspects played a subordinate role. In comparison to telephone calls, a significant improvement in the physician-patient relationship (p-value = 0.00027), the quality of treatment and information (p-value both = 0.00044), the access to care (p-value = 0.0053) and the communication (p-value = 0.021) was assumed. An improvement in access to care (p-value = 0.021) and the quality of information (p-value = 0.034) was seen in comparison to personal contact. The main problems were a lack of experience, technical requirements, technical problems and unpunctuality of the practitioner. The flexibility, low effort and the pleasant consultation were all praised. All subjects wanted to use the video consultation again. CONCLUSION: Video consultation can represent a supplement to treatment of patients under lipid management. The correct use requires exact planning and further research.

RESUMO

Prostate cancer is the most prevalent noncutaneous cancer in men. The Gleason grading is considered to be the strongest prognostic parameter regarding progression-free survival and overall survival. The original grading system has been modified during the last decade resulting in a more precise prognostic tool. The pretreatment Gleason score guides clinical management and is a key component in S3 guidelines for prostate cancer. In addition to Gleason score several other histologic findings in prostate needle biopsy influence patient management. In this second part of our CME series about prostate cancer, we will discuss the diagnosis of prostate cancer and current guidelines for reporting prostate cancer. In addition, we will highlight prostate lesions of urothelial origin and neuroendocrine prostate cancer as well as prognostic biomarkers.

RESUMO

PURPOSE: To determine the frequency of cataract surgery in Germany and to evaluate its impact on visual function in an adult population. METHODS: The population-based Gutenberg Health Study was conducted in Germany with its baseline examination between 2007 and 2012 and a 5-year follow-up examiantion. An ophthalmological examination including slit-lamp examination, ocular biometry, and Scheimpflug imaging was carried out. Overall and age-specific frequencies of unilateral and bilateral cataract surgery within 5 years were computed including the 95% confidential intervals [95%-CI]. Association analyses were conducted to determine social and ocular associated factors using multivariable logistic regression analysis. Vision-related quality of life was assessed using NEI VFQ-25. RESULTS: A total of 10,544 people aged 35 to 74 years were bilateral phakic at baseline and had information on lens status at the 5-year examination. Of these, 168 had unilateral cataract surgery (1.6% [1.4-1.9%]), and 448 had bilateral cataract surgery (4.2% [3.9-4.7%]) in the following 5 years. The frequency of cataract surgery increased with age: 45-54-year-old subjects had twice as often cataract surgery (in at least on eye: OR = 2.32) than at age 35-44 years. The frequency further strongly increases with age (55-64 years: OR = 10.5; 65-74 years: OR = 43.8, p < 0.001). Subjects with glaucoma were more likely to have cataract surgery (OR = 2.52, p < 0.001). Visual function increased when undergoing bilateral cataract surgery. CONCLUSIONS: The frequency of cataract surgery is low at younger ages and increases up to 26% at age 70-74 years. Persons with glaucoma are more likely to undergo cataract surgery at population-based level in Germany.

RESUMO

Aims: The cardiac and vascular late sequelae in long-term survivors of childhood cancer (CVSS)-study aimed to quantify the prevalence of cardiovascular risk factors (CVRF) and cardiovascular disease (CVD) in German childhood cancer survivors (CCS). Methods and results: In the CVSS-study (NCT02181049), 1002 CCS (age range 23-48 years) diagnosed with neoplasia prior to 15 years of age between 1980 and 1990 prospectively underwent a systematic, standardized clinical and laboratory cardiovascular screening, identical to the population-based Gutenberg Health Study (GHS) cohort. For 951 individuals, prevalences of CVRF and CVD were primarily compared to the GHS sample and to two further German population-based cohorts. Using log-binomial regression models, an increased risk for occurrence of arterial hypertension [relative risk (RR) 1.38, 95% confidence interval (95% CI 1.21-1.57)] and dyslipidaemia [RR 1.26 (95% CI 1.12-1.42)] was found. This indicates a premature occurrence compared to the general population of approximately 6 and 8 years, respectively [rate advancement period estimator, RAPhypertension 5.75 (95% CI 3.5-8.0) and RAPdyslipidaemia 8.16 (95% CI 4.4-11.9)]. Overall, no differences were observed for obesity and diabetes. Overt CVD was present in 4.5% (95% CI 3.0-6.6%) of CCS [RR 1.89 (95% CI 1.34-2.66), RAPCVD 7.9 (95% CI 4.1-11.7)], of which the most frequent entities were congestive heart failure and venous thromboembolism. Prevalences of CVRF and CVD increased with age without reaching a plateau over time. Conclusion: This large CCS screening examination revealed consistently in comparison to three population samples a considerably increased risk for premature CVD. The findings in these young adult CCS indicate a high burden of cardiovascular morbidity and mortality in the long term. Clinicaltrials. gov-Nr: NCT02181049.

RESUMO

BACKGROUND: Major depression and anxiety disorders are known to negatively influence cognitive performance. Moreover, there is evidence for greater cognitive decline in older adults with generalized anxiety disorder. Except for clinical studies, complex executive planning functions and subclinical levels of anxiety have not been examined in a population-based sample with a broad age range. METHODS: Planning performance was assessed using the Tower of London task in a population-based sample of 4240 participants aged 40-80 years from the Gutenberg Health Study (GHS) and related to self-reported anxiety and depression by means of multiple linear regression analysis. RESULTS: Higher anxiety ratings were associated with lower planning performance (ß = -0.20; p < 0.0001) independent of age (ß = 0.03; p = 0.47). When directly comparing the predictive value of depression and anxiety on cognition, only anxiety attained significance (ß = -0.19; p = 0.0047), whereas depression did not (ß = -0.01; p = 0.71). CONCLUSIONS: Subclinical levels of anxiety but not of depression showed negative associations with cognitive functioning independent of age. Our results demonstrate that associations observed in clinical groups might differ from those in population-based samples, also with regard to the trajectory across the life span. Further studies are needed to uncover causal interrelations of anxiety and cognition, which have been proposed in the literature, in order to develop interventions aimed at reducing this negative affective state and to improve executive functioning.

RESUMO

BACKGROUND: To investigate the prevalence of depression and anxiety among subjects with self-reported glaucoma and the association between self-reported glaucoma and depression respectively anxiety in a European cohort. METHODS: A study sample of 14,657 participants aged 35 to 74 years was investigated in a population-based cohort study. All participants reported presence or absence of glaucoma. Ophthalmological examinations were carried out in all participants and demographic and disease related information were obtained by interview. Depression was assessed with the Patient Health Questionnaire (PHQ-9), and generalized anxiety with the two screening items (GAD-2) of the short form of the GAD-7 (Generalized Anxiety Disorder-7 Scale). Prevalence of depression and generalized anxiety were investigated for subjects with and without self-reported glaucoma. Logistic regression analyses with depression, respectively anxiety as dependent variable and self-reported glaucoma as independent variable were conducted and adjusted for socio-demographic factors, systemic comorbidities (arterial hypertension, myocardial infarction, stroke, diabetes mellitus, chronic obstructive pulmonary disease, cancer), ocular diseases (cataract, macular degeneration, corneal diseases, diabetic retinopathy), visual acuity, intraocular pressure, antiglaucoma eye drops (sympathomimetics, parasympathomimetics, carbonic anhydrase inhibitors, beta-blockers, prostaglandins) and general health status. RESULTS: 293 participants (49.5% female) reported having glaucoma. Prevalence of depression among participants with and without self-reported glaucoma was 6.6% (95%-CI 4.1-10.3) respectively 7.7% (95%-CI 7.3-8.2), and for anxiety 5.3% (95%-CI 3.1-8.7) respectively 6.6% (95%-CI 6.2-7.1). Glaucoma was not associated with depression (Odds ratio 1.10, 95%-CI 0.50-2.38, p = 0.80) or anxiety (1.48, 95%-CI 0.63-3.30, p = 0.35) after adjustment for socio-demographic factors, ocular/systemic diseases, ocular parameters, antiglaucoma drugs and general health status. A restriction to self-reported glaucoma cases either taking topical antiglaucoma medications or having a history of glaucoma surgery did not alter the result. CONCLUSIONS: This is the first study analyzing both depression and anxiety among glaucoma patients in a European cohort. Subjects with and without self-reported glaucoma had a similar prevalence of depression and anxiety in our population-based sample. Self-reported glaucoma was not associated with depression or anxiety. A lack of a burden of depressive symptoms may result from recruitment from a population-based sample as compared to previous study groups predominantly recruited from tertiary care hospitals.

RESUMO

The incidence of cardiovascular diseases can be reduced by the early detection and targeted treatment of risk factors and subclinical forms of the disease. Primary prevention provides several opportunities for successful interventions. In addition to a drug-based therapy, especially life style-modifying measures, such as physical activity, normalization of body weight, consistent nicotine abstinence and the consideration of psychosocial aspects represent core components of prevention programs. Healthcare data indicate that risk factors still often remain undetected and that the full potential of risk factor management has not yet been fully exploited at a population level. Especially motivation of patients and adherence to therapy represent key elements of successful prevention efforts.

RESUMO

BACKGROUND: While work-related fatigue has become an issue of concern among European employees, the relationship between fatigue, depression and work-related stressors is far from clear. The purposes of this study were (1) to determine the associations of fatigue with work-related stressors, severe medical disease, health behavior and depression in the working population and (2) to determine the unique impact of work-related stressors on fatigue. METHODS: We used cross-sectional data of N = 7,930 working participants enrolled in the Gutenberg Health Study (GHS) from 2007 to 2012 filled out the Personal Burnout Scale (PBS) of the Copenhagen Psychosocial Questionnaire (COPSOQ), the PHQ-9, and a list of work-related stressors. RESULTS: A total of 27.5% reported increased fatigue, esp. women, younger persons with a lower social status and income, smokers, severely medically ill, previously and currently depressed participants. Fatigue was consistently associated with severe medical disease, health behavior and depression, which need to be taken into account as potential confounders when analyzing its relationship to work-related strains. Depression was consistently associated with work-related stressors. However, after statistically partialling out depression, fatigue was still significantly associated with work-related stress. CONCLUSIONS: Fatigue as an indicator of allostatic load is consistently associated with work-related stressors such as work overload after controlling for depression. The brief Personal Burn-out Scale is suitable for assessing work-related fatigue in the general population.

RESUMO

PURPOSE: The study examines the association between exposure to current and cumulative night shift work and subclinical parameters of atherosclerosis. METHODS: Participants of a population-based cohort study (the Gutenberg Health Study, N = 15,010) aged 35-64 years were examined at baseline (2007-2012). Investigations included measurements of arterial stiffness, vascular function [reactive hyperaemia (RH) index], and intima media thickness (IMT). Also, a complete job history (including up to 15 periods), occupational exposures, a variety of lifestyle, and dispositional variables were enquired. RESULTS: Night shift work was performed by 1071 out of 8065 currently employed individuals. The strongest association after adjustment for age, sex, job complexity level, being a manager, overtime work, and noise appeared for more than 660 night shifts within the last 10 years and a significantly increased arterial stiffness of 0.33 m/s. This reflects a 4 % flow velocity increase for individuals with more than 660 night shifts compared to non-night workers. Regarding the entire professional life, night shift workers showed a significantly decreased vascular function by -0.054 RH index points by using the same adjustment. IMT values did not differ statistically from non-night workers. Lifestyle and dispositional factors showed an influence on all used subclinical atherosclerosis parameters. CONCLUSIONS: The cross-sectional results demonstrate an association between night work and detrimental changes in the atherosclerotic process. The association is more pronounced with more years in night shift and is partly explained by lifestyle and dispositional factors. Longitudinal analyses are necessary to confirm the results.

RESUMO

Genome-wide association studies have identified and repeatedly confirmed the association of rs3197999 in MST1 with inflammatory bowel disease (IBD). However, the underlying pathophysiology remains unclear. rs3197999 is a non-synonymous single-nucleotide polymorphism which modifies the function of macrophage stimulating protein-1 (MST1). We show by haplotyping that rs3197999 is in linkage disequilibrium with rs1050450 in GPX1, with almost complete cosegregation of the minor alleles. As shown by immunoassay, rs3197999 influences the MST-1 level in serum. But also rs1050450 causes an amino acid exchange in glutathione peroxidase 1 (GPx-1) and reduced activity of this antioxidant enzyme. The association of GPx deficiency and IBD in mice was already shown. We propose that GPx-1 is a better candidate than MST1 for the pathophysiologic link between IBD locus 12 and IBD.

RESUMO

BACKGROUND: Treatment planning of localised prostate cancer remains challenging. Besides conventional parameters, a wealth of prognostic biomarkers has been proposed so far. None of which, however, have successfully been implemented in a routine setting so far. The aim of our study was to systematically verify a set of published prognostic markers for prostate cancer. METHODS: Following an in-depth PubMed search, 28 markers were selected that have been proposed as multivariate prognostic markers for primary prostate cancer. Their prognostic validity was examined in a radical prostatectomy cohort of 238 patients with a median follow-up of 60 months and biochemical progression as endpoint of the analysis. Immunohistochemical evaluation was performed using previously published cut-off values, but allowing for optimisation if necessary. Univariate and multivariate Cox regression were used to determine the prognostic value of biomarkers included in this study. RESULTS: Despite the application of various cut-offs in the analysis, only four (14%) markers were verified as independently prognostic (AKT1, stromal AR, EZH2, and PSMA) for PSA relapse following radical prostatectomy. CONCLUSIONS: Apparently, many immunohistochemistry-based studies on prognostic markers seem to be over-optimistic. Codes of best practice, such as the REMARK guidelines, may facilitate the performance of conclusive and transparent future studies.

RESUMO

Atrial fibrillation (AF) is a disease with increasing clinical and public health importance. We describe the prevalence of AF, the current distribution of AF risk factors and their importance in a general population. The distribution of AF risk factors and the medicinal treatment were determined among 10,000 individuals in the population-based Gutenberg Health Study (median age 56 years and 49% women). Individuals with AF (n=309, 3.1%) had a higher median age (67 years) and significantly more risk factors. A large percentage of individuals with AF were taking antithrombotic medication (84% with a CHAD2DS2-VASc score of ≥3). Multiple logistic regression analysis showed that male gender (odds ratio, OR 2.07, 95% CI: 1.59-2.71), age (OR 1.09, 95% CI: 1.07-1.11), body mass index (OR 1.04, 95% CI: 1.02-1.07), prevalent cardiovascular disease (OR 3.06, 95% CI: 2.26-4.11) and heart failure (OR 3.11, 95% CI: 1.92-4.97) were the strongest predictors of AF. The full model explained 18% (Nagelkerke's determination coefficient R(2)) of the variation in AF prevalence. The addition of echocardiographic variables in a subgroup analysis with 5.000 participants increased the explained variation to 23%. AF is a common disease in the general population. Important risk factors for AF, apart from age and male gender, were cardiovascular disease, in particular heart failure, hypertension and increased body mass index. Awareness for AF in the population and medical community needs to be improved.

RESUMO

OBJECTIVES: To test the vascular depression hypothesis in the general population, we analyzed the association between current depression, medical history of depression, cognitive and somatic depressive symptom dimensions and measures of atherosclerosis [intima-media thickness (IMT) and carotid plaques]. METHOD: We included a representative sample of 5000 participants from the Gutenberg Health Study (GHS). Depression was assessed by the nine-item Patient Health Questionnaire (PHQ-9), and IMT and carotid plaques were measured at both common carotid arteries using an edge detection system. Regression analyses were performed separately for participants with and without cardiovascular disease, adjusting for medical history, cardiovascular risk factors and psychotropic medication. RESULTS: Contrary to hypotheses, we found no increased IMT for somatic symptoms of depression; the same was true for depression and cognitive symptoms in the fully adjusted model. Only a moderate relationship between medical history of depression and the presence of atherosclerotic plaques was maintained after correction. CONCLUSIONS: The relationship between depression and atherosclerosis may be more complex than previously assumed. Although the vascular depression hypothesis was not supported, our results support the hypothesis that lasting depression leads to arteriosclerosis.

RESUMO

Fluorescence confocal microscopy (FCM) is an optical technique that uses laser light sources of different wavelengths to generate real-time images of fresh, unfixed tissue specimens. FCM allows histological evaluation of fresh tissue samples without the associated cryo artifacts after frozen sectioning. The aim of this study was to prospectively evaluate pediatric tumor specimens and assess their suitability for fresh tumor sampling. In addition, we aimed to determine whether tumor cell isolation for stable cell culture is still feasible after FCM imaging. Pediatric tumor specimens were imaged using FCM. Tumor viability and suitability for tissue sampling were evaluated and compared with H&E staining after paraffin embedding. In addition, FCM-processed and non-FCM-processed tissue samples were sent for tumor cell isolation to evaluate possible effects after FCM processing. When comparing estimated tumor cell viability using FCM and H&E, we found good to excellent correlating estimates (intraclass correlation coefficient = 0.891, p < 0.001), as well as substantial agreement in whether the tissue appeared adequate for fresh tissue collection (κ = 0.762, p < 0.001). After FCM, seven out of eight samples yielded passable cell cultures, compared to eight out of eight for non-FCM processed samples. Our study suggests that the use of FCM in tumor sampling can increase the yield of suitable fresh tumor samples by identifying viable tumor areas and ensuring that sufficient tissue remains for diagnosis. Our study also provides first evidence that the isolation and growth of tumor cells in culture are not compromised by the FCM technique.

RESUMO

Type II endometrial carcinomas are a highly aggressive group of tumor subtypes that are frequently associated with inactivation of the TP53 tumor suppressor gene. We show that mice with endometrium-specific deletion of the Trp53 gene initially exhibited histological changes that are identical to known precursor lesions of type II endometrial carcinomas in humans and later developed carcinomas representing all type II subtypes. The mTORC1 signalling pathway was frequently activated in these precursor lesions and tumors, suggesting a genetic cooperation between this pathway and Trp53 deficiency in tumor initiation. Consistent with this idea, analyses of 521 human endometrial carcinomas identified frequent mTORC1 pathway activation in type I as well as type II endometrial carcinoma subtypes. The mTORC1 pathway activation and p53 expression or mutation status each independently predicted poor patient survival. We suggest that molecular alterations in p53 and the mTORC1 pathway play different roles in the initiation of the different endometrial cancer subtypes but combined p53 inactivation and mTORC1 pathway activation are unifying pathogenic features among histologically diverse subtypes of late stage aggressive endometrial tumors.

RESUMO

Using a cobot could relieve workers of strenuous and repetitive tasks while preserving their expertise. To understand the consequences of using a cobot on the occurrence of musculoskeletal disorders (MSDs), within a theoretical framework based on activity-centred ergonomics, an example cobot used in grinding activities in a real work situation is studied. This article analyses the evolution of the biomechanical dimension of the professional gestures of grinders when using the cobot. Effort linked to tool carrying and the vibrations perceived were reduced. Repetitiveness decreased but workers did not accomplish the entirety of their task. The work postures did improve for different joints but not for all, which shows the advantage of varying the contexts of using a cobot and taking into account workers' strategy diversity. To investigate other explanatory elements of the effects on MSDs, these results must be linked to the evolution of the other dimensions of professional gestures.

RESUMO

BACKGROUND AND AIMS: In prostate cancer patients, application of the NeuroSAFE frozen section technique during radical prostatectomy has been shown to increase the rate of nerve sparing surgery and to improve functional outcome for the patients. The aim of this study is to report on technical and organizational optimization opportunities of the procedure. MATERIAL AND METHODS: All patients submitted to bilateral intraoperative frozen section from January 2018 until December 2020 (n = 452) were retrospectively analyzed and parameters such as turnaround time, staff situation in the laboratory and histologic properties of the tumors were assessed. RESULTS: The median turnaround time per case was 40.3 ( ± 10.5) min. In 2020 the average time needed from accessioning to diagnosis was 38.1 min. Multivariate linear regression suggested that the number of technical assistants/cryotomes (46.1 min vs. 39.13 min; p < 0.001), the place of microscopic examination (43.0 min vs. 38.7 min; p < 0.001) and the presence of a positive margin (38.0 vs. 44.0 min; p < 0.001) were significant influential factors. The turnaround time was independent of the uropathological expertize of the consultant (39.84 min vs. 40.7 min; p = 0.09), the tumor grade (42.3 vs 39.8 min; p = 0.493) and the presence of extraprostatic extension (44.0 vs 39.8 min; p = 0.099). CONCLUSION: The implementation of simple optimization measures in the workflow as well as structured training of all pathology staff involved in the examination leads to a significant increase in the efficiency of the examination while maintaining the same level of resources. The results could thus be a contribution to the broader application of the procedure.

RESUMO

BACKGROUND: A significant proportion of patients with peripheral artery disease (PAD) displays a poor response to aspirin and/or the platelet P2Y12 receptor antagonist clopidogrel. This phenomenon is reflected by high on-treatment platelet reactivity (HTPR) in platelet function assays in vitro and is associated with an increased risk of adverse cardiovascular events. OBJECTIVE: This study aimed to elucidate specific plasma protein signatures associated with HTPR to aspirin and clopidogrel in PAD patients. METHODS AND RESULTS: Based on targeted plasma proteomics, 184 proteins from two cardiovascular Olink panels were measured in 105 PAD patients. VerifyNow ASPI- and P2Y12-test values were transformed to a continuous variable representing HTPR as a spectrum instead of cut-off level-defined HTPR. Using the Boruta random forest algorithm, the importance of 3 plasma proteins for HTPR in the aspirin, six in clopidogrel and 10 in the pooled group (clopidogrel or aspirin) was confirmed. Network analysis demonstrated clusters with CD84, SLAMF7, IL1RN and THBD for clopidogrel and with F2R, SELPLG, HAVCR1, THBD, PECAM1, TNFRSF10B, MERTK and ADM for the pooled group. F2R, TNFRSF10B and ADM were higher expressed in Fontaine III patients compared to Fontaine II, suggesting their relation with PAD severity. CONCLUSIONS: A plasma protein signature, including eight targets involved in proatherogenic dysfunction of blood cell-vasculature interaction, coagulation and cell death, is associated with HTPR (aspirin and/or clopidogrel) in PAD. This may serve as important systems-based determinants of poor platelet responsiveness to aspirin and/or clopidogrel in PAD and other cardiovascular diseases and may contribute to identify novel treatment strategies.
