RESUMO

BACKGROUND: Based on a quality assurance initiative of the German Society for Thoracic and Cardiovascular Surgery (DGTHG) and the German Society for Pediatric Cardiology and Congenital Heart Defects (DGPK), a voluntary registry was founded for assessment of treatment and outcomes of patients with congenital heart disease in Germany. This evaluation by the German Registry for cardiac operations and interventions in patients with congenital heart disease reports the data and the outcome over a 6-year period in patients undergoing invasive treatment. METHODS: This real-world database collects clinical characteristics, in-hospital complications, and medium-term outcome of patients who underwent cardiac surgical and interventional procedures within the prospective, all-comers registry. Patients were followed-up for up to 90 days. RESULTS: In the period from 2013 to 2018, a total of 35,730 patients, 39,875 cases, respectively 46,700 procedures were included at up to 31 German institutions. The cases could be subcategorized according to the treatment intention into 21,027 (52.7%) isolated operations, 17,259 (43.3%) isolated interventions, and 1,589 (4.0%) with multiple procedures. Of these, 4,708 (11.8%) were performed in neonates, 10,047 (25.2%) in infants, 19,351 (48.5%) in children of 1 to 18 years, and 5,769 (14.5%) in adults. Also, 15,845 (33.9%) cases could be allocated to so-called index procedures which underwent a more detailed evaluation to enable meaningful comparability. The mean unadjusted in-hospital mortality of all cases in our registry ranged from 0.3% in patients with isolated interventions and 2.0% in patients with surgical procedures up to 9.1% in patients undergoing multiple procedures. CONCLUSION: This annually updated registry of both scientific societies represents voluntary public reporting by accumulating actual information for surgical and interventional procedures in patients with congenital heart disease (CHD) in Germany. It describes advancements in cardiac medicine and is a basis for internal and external quality assurance for all participating institutions. In addition, the registry demonstrates that in Germany, both interventional and surgical procedures for treatment of CHD are offered with high medical quality.

RESUMO

Dwindling fossil fuels force humanity to search for new energy production routes. Besides energy generation, its storage is a crucial aspect. One promising approach is to store energy from the sun chemically in strained organic molecules, so-called molecular solar thermal (MOST) systems, which can release the stored energy catalytically. A prototypical MOST system is norbornadiene/quadricyclane (NBD/QC) whose energy release and surface chemistry need to be understood. Besides important key parameters such as molecular weight, endergonic reaction profiles, and sufficient quantum yields, the position of the absorption onset of NBD is crucial to cover preferably a large range of sunlight's spectrum. For this purpose, one typically derivatizes NBD with electron-donating and/or electron-accepting substituents. To keep the model system simple enough to be investigated with photoemission techniques, we introduced bromine atoms at the 2,3-position of both compounds. We study the adsorption behavior, energy release, and surface chemistry on Ni(111) using high-resolution X-ray photoelectron spectroscopy (HR-XPS), UV photoelectron spectroscopy, and density functional theory calculations. Both Br2-NBD and Br2-QC partially dissociate on the surface at ∼120 K, with Br2-QC being more stable. Several stable adsorption geometries for intact and dissociated species were calculated, and the most stable structures are determined for both molecules. By temperature-programmed HR-XPS, we were able to observe the conversion of Br2-QC to Br2-NBD in situ at 170 K. The decomposition of Br2-NBD starts at 190 K when C-Br bond cleavage occurs and benzene and methylidene are formed. For Br2-QC, the cleavage already occurs at 130 K when cycloreversion to Br2-NBD sets in.

RESUMO

Congenital heart diseases (CHD) are the most common types of congenital organ defects. Thanks to medical progress in congenital cardiology and heart surgery, most children with CHD reach adulthood. Despite primarily successful treatment residual and subsequent conditions as well as (non)cardiac comorbidities can influence the chronic course of the disease and lead to a higher morbidity and mortality. Adults with congenital heart disease (ACHD) in Germany are not tied to the healthcare structure despite the great need for aftercare. According to the results of the medical care of ACHD (MC-ACHD) study, ACHD centers and specialists in Germany are insufficiently perceived despite increased complication rates and the great need for specialist guidance. General practitioners and patients are not adequately informed about existing ACHD facilities. A better awareness of the ACHD problem should be created at the level of primary medical supply in order to optimize care and to reduce morbidity and mortality. Improved future-oriented patient care includes lifelong regular follow-up and the possibility of interdisciplinary, integrated medical care of CHD.

RESUMO

OBJECTIVE: The aim of this prospective split sample study was to evaluate the applicability of liquid-based cytology (LBC) of oral brush biopsies for detection of oral cancer. METHODS: Two different preparation techniques were investigated: the conventional transfer procedure to glass slides and the LBC preparation method. The obtainments of epithelial cells were performed five times with a nylon brush and transferred onto five glass slides. Additionally, the brushes, which were normally discarded, were stored in a fixative solution. Conventional slides and respective thin layers from a total of 113 cases were reviewed with both techniques. RESULTS: Thin layers showed excellent morphology on a clear background, which allowed an accurate diagnosis. In contrast, the conventional glass slides showed significantly more blood contamination and cell overlapping. The sensitivity of conventional cytological diagnosis was 96.3%, the specificity archived 90.6%, the positive predictive value was 96.3% and the negative predictive value scored 90.6%. The sensitivity of the cytological diagnosis using thin layers archived 97.5%, the specificity was 68.8%, the positive predictive value revealed 88.76% and negative predictive value was 91.7%. CONCLUSION: Our findings indicate that in oral cytology, LBC may replace other types of wet-fixed preparations using the full amount of collected cells, resulting in enhanced specimen quality archiving comparable values of diagnostic accuracy. CLINICAL RELEVANCE: LBC facilitates the cell collection due to simpler handling and less transfer errors by dentists and may improve the overall diagnostic accuracy of oral brush biopsies in future.

RESUMO

Based on level I evidence, postoperative platinum-based radiochemotherapy (PORCT) is the recommended standard of care in defined risk situations after resection of squamous cell carcinomas of the larynx and hypopharynx (LHSCC). The value of the addition of chemotherapy to adjuvant radiation in intermediate and high risk situations other than extracapsular spread or R1-/R2 resection is still debated. From 1993 to 2009, 555 patients (median follow-up: 24.4 months) with advanced LHSCC (UICC stages III-IVB) were treated in a curative intent. Patient data were continuously documented in the county of Leipzig cancer registry and were retrospectively analyzed as mono institutional survey. PORCT was introduced into the standard procedures in 2004, but also applied before in selected cases. Based on this paradigm shift, the patient population was divided into two comparative groups treated before and after 2004. 361 patients were treated before 2004. 43.8 % received primary surgery (OP) + postoperative radiotherapy (PORT) and 20.2 % OP + PORCT. 194 patients were treated after 2004: 21.1 % received OP + PORT and 35.6 % OP + PORCT. Regarding the PORCT groups, 20.6 % received cisplatin plus 5FU before 2004 which shifted to 59.4 % after 2004. The 3-year tumor-specific-survival rate of the whole cohort was improved from 47 to 60 % (p = 0.006). The subgroup treated with OP + PORT or PORCT improved from 56.1 to 68.5 % (p = 0.028). Localization proved to be a significant and independent factor. Only patients with advanced laryngeal cancer had significant improved survival (p < 0.01), while the improvement for hypopharyngeal cancer patients was not significant (p < 0.2). After 2004, there was a slight increase (+10.2 %) of primary radiochemotherapy (pRCT) due to stronger selection if R0 > 5 mm-resectability is unlikely. Standardised use of PORCT and pRCT considering clear indications showed to be significantly involved in improved survival in advanced LHSCC.

RESUMO

Children of parents who suffer from mental health disorders are more likely to develop mental disorders than children of parents not suffering from mental disorders. For children at risk, preventive strategies are hardly available and, if available, rarely supported by a scientific evaluation. "Kanu - Gemeinsam weiterkommen (canoe - moving jointly forward)" is a preventive strategy that was developed within a research project focusing on primary prevention in children who live in families with parents affected by mental disorders. The intervention is characterised by a multi-modular concept and was tested in the adult psychiatric setting. Preliminary results indicate a preventive impact of the intervention programme.

RESUMO

Research-based evidence and practice-based experience are core requirements for the effective implementation of preventive interventions. The knowledge gained in the Prevention Research Funding Initiative of the German Federal Ministry of Education and Research (2004-2013) was therefore amalgamated, reflected and consolidated in the Cooperation for Sustainable Prevention Research (KNP) meta-project. In annual strategy meetings, researchers and practitioners from the field and other experts developed 3 memoranda providing recommendations for the further development of research and practice in the field of prevention and health promotion. Memorandum III is primarily aimed at decision-makers in politics and administration at the federal, state and local level, in civil society and in the workplace. Its recommendations show that structuring efforts are urgently needed to achieve sustainable policy, particularly in the fields of health, education, employment and social affairs. Memorandum III brings together the knowledge extracted and problems identified in research projects. More so than its 2 predecessors, Memorandum III abstracts knowledge from the individual projects and attempts to derive guidance for action and decision-making, as shown by the 7 recommendations that appear to useful for consensus-building in practice and research. Value judgments are inevitable. Prevention and health promotion are an investment in the future: of social health, social capital and social peace. Improvement of the framework conditions is needed to achieve the harmonized awareness and the sustained effectiveness of these structure-building efforts in different policy areas, spheres of life, fields of action, and groups of actors. This includes the implementation of an overall national strategy as well as the expansion of sources of funding, extension of the legal framework, overarching coordination, and the establishment of a National Center of Excellence to develop and safeguard prevention and health promotion. The memorandum is intended to stimulate a discourse resulting in structure-building and stabilizing measures designed to ensure the sustainability of prevention and health promotion.

RESUMO

BACKGROUND: Health literacy is multidisciplinary and brings together many concepts, and is of increasing importance for disease protection, health promotion, and prevention, and for health policy within Europe. Although its importance is increasingly recognised, adults are mostly the target audience, whereas children and adolescents, in addition to education and schools, have so far been neglected. OBJECTIVES: The aim is to give an overview of the state of the art in childhood and adolescence health literacy research, and to identify any existing gaps. MATERIALS: A literature review has been performed to identify the relevant research data. RESULTS: Limitations in developmental and age-adjusted conceptual frameworks and a lack of prevalence data, however, significantly impede our understanding of the meaning of health literacy in children and adolescents. School health promotion programmes could serve as a platform for effective health literacy education, beginning in early childhood. CONCLUSIONS: In addition to compatibility with a broader literacy perspective, the proximity to several theories of health promotion and defined concepts, and the importance of school health promotion and education, it is vital to focus research on current gaps in the understanding of health literacy determinants, health literacy as a determinant of health, and in terms of the design and systematic implementation of intervention programmes.

RESUMO

The effect of electron confinement on the magnetocrystalline anisotropy of ultrathin bcc Fe films is explored by combining photoemission spectroscopy, x-ray magnetic circular dichroism, and magneto-optical Kerr effect measurements. Pronounced thickness-dependent variations in the magnetocrystalline anisotropy are ascribed to periodic changes in the density of states at the Fermi level, induced by quantization of d(xz), d(yz) out-of-plane orbitals. Our results reveal a direct correlation between quantum well states, the orbital magnetic moment, and the magnetocrystalline anisotropy.

RESUMO

By improvement of the medical care, children with congenital heart disease survive in much greater numbers: the figure of ACHD-patients in Germany is estimated up to 203,000 to 301,000. The need for a specialized care of these patients is accepted by the scientific societies, who introduced a certification for doctors and centers and created guidelines. The medical problems include imaging, treatment of arrhythmia, congestive heart failure and cyanosis, prophylaxis of infectious endocarditis, exercise and pregnancy. For the most frequent defects, indication for treatment and postoperative care is summarized.

RESUMO

Ebstein's anomaly is a rare congenital heart malformation characterised by adherence of the septal and posterior leaflets of the tricuspid valve to the underlying myocardium. Associated abnormalities of left ventricular morphology and function including left ventricular noncompaction (LVNC) have been observed. An association between Ebstein's anomaly with LVNC and mutations in the sarcomeric protein gene MYH7, encoding ß-myosin heavy chain, has been shown by recent studies. This might represent a specific subtype of Ebstein's anomaly with a Mendelian inheritance pattern. In this review we discuss the association of MYH7 mutations with Ebstein's anomaly and LVNC and its implications for the clinical care for patients and their family members.

RESUMO

Protozoa, cyanobacteria, sheathed algae, sheathed fungi, germinating pollen or spores, and fungal spores have been found in amber 220 to 230 million years old. Many of these microorganisms can be assigned to present-day groups. This discovery of terrestrial, soft-bodied protists that can be referred to modern groups indicates that morphological evolution is very gradual in many protists and that both structural and probably functional stasis extend back at least to the Upper Triassic period.

RESUMO

Inequalities in health care are often discussed in an undifferentiated way in Germany. Against this background, this article presents an analysis scheme for a classification of relevant studies and an identification of research needs. To this aim, areas of health care are differentiated (ambulant and inpatient care, prevention and health promotion) and a difference is made between access, utilization and quality of care. According to this scheme, research regarding inequalities in health care can be conducted in nine fields. For each field, exemplary results of a recent study from Germany are summarized. It becomes apparent that there is a substantial lack of systematic research in inequalities in health care in Germany.

RESUMO

BACKGROUND: On 28 June 2004, New York State (NY) became the first jurisdiction to require cigarettes to meet a reduced ignition propensity (RIP) standard. This law resulted in cigarette manufacturers modifying nearly all of their brands sold in NY. However, the same cigarette brands sold in other states were not modified to meet the RIP standard. OBJECTIVES: This paper examines relationships between the RIP law and smokers' awareness of changes in the performance of their cigarettes (that is, going out more frequently, change in taste), and smoking behaviour. METHODS: Data for this analysis come from a nationwide survey of 2088 adult smokers (> 18 years of age) conducted in the USA between July and December 2004. 143 of the smokers included in the survey were residents of NY while the remainder were from other states (n = 1945). Survey participants were asked whether their cigarettes "ever go out between puffs" and whether they had noticed any change in the taste of their cigarettes in the past 12 months. RESULTS: NY smokers were three times more likely than smokers in other states to report that their cigarettes often went out between puffs (17.3% v 5.6%). However, NY smokers appeared no more likely to report noticing differences in cigarette taste, an intention to quit smoking, or to have made quit attempts. CONCLUSIONS: A significant minority of smokers in NY reported noticing changes in the performance of their cigarettes following the RIP law, as would be expected. However, the RIP law appears to have had no impact on the smoking habits of New Yorkers, countering arguments made by cigarette manufacturers that the law would impact consumer acceptability.

RESUMO

AIMS: For women with congenital heart defects (CHD), pregnancy may pose a health risk. Sexually active women with CHD without the desire for own children or for whom pregnancy would imply considerable health risks require adequate counselling regarding appropriate contraception. This study gathers data on the contraceptive behaviour of women with CHD from three different cultural regions. METHODS AND RESULTS: 634 women with CHD from Germany, Hungary and Japan were surveyed regarding contraception and contraceptive methods (CM) used. The patients were divided into groups according to different criteria such as pregnancy associated cardiovascular risk or "safety" of the contraceptive methods used. 59% of the study participants had already gained experience with CM. The average age at the first time of use was 18.4 years; the German patients were significantly younger at the first time of using a CM than those from Hungary and Japan. Overall the condom was the method used the most (38%), followed by oral contraceptives (30%) and coitus interruptus (11%). The range of CM used in Japan was much smaller than that in Germany or Hungary. Unsafe contraceptives were currently, or had previously been used, by 29% of the surveyed patients (Germany: 25%, Hungary: 37%, Japan: 32%). CONCLUSION: Most women with CHD use CM. There are differences between the participating countries. Adequate contraceptive counselling of women with CHD requires considering the individual characteristics of each patient, including potential contraindications. For choosing an appropriate CM, both the methods' "safety", as well as the maternal cardiovascular risk, are important.

RESUMO

BACKGROUND: Impairment of ventilatory efficiency in congestive heart failure (CHF) correlates well with symptomatology and contributes importantly to dyspnea. METHODS AND RESULTS: We investigated 142 CHF patients (mean NYHA class, 2.6; mean maximum oxygen consumption [VO(2)max], 15.3 mL O(2) x kg(-1) x min(-1); mean left ventricular ejection fraction [LVEF], 27%). Patients were compared with 101 healthy control subjects. Cardiopulmonary exercise testing was performed, and ventilatory efficiency was defined as the slope of the linear relationship of V(CO(2)) and ventilation (VE). Results are presented in percent of age- and sex-adjusted mean values. Forty-four events (37 deaths and 7 instances of heart transplantation, cardiomyoplasty, or left ventricular assist device implantation) occurred. Among VO(2)max, NYHA class, LVEF, total lung capacity, and age, the most powerful predictor of event-free survival was the VE versus V(CO(2)) slope; patients with a slope 130% (54.7%; P<0.001). CONCLUSIONS: The VE versus V(CO(2)) slope is an excellent prognostic parameter. It is easier to obtain than parameters of maximal exercise capacity and is of higher prognostic importance than VO(2)max.

RESUMO

OBJECTIVE: To assess the impact on hospitality workers' exposure to secondhand smoke of New York's smoke-free law that prohibits smoking in all places of employment, including restaurants, bars, and bowling facilities. DESIGN: Pre-post longitudinal follow up design. SETTINGS: Restaurants, bars, and bowling facilities in New York State. SUBJECTS: At baseline, 104 non-smoking workers in restaurants, bars, and bowling facilities were recruited with newspaper ads, flyers, and radio announcements. Of these, 68 completed a telephone survey and provided at least one saliva cotinine specimen at baseline. At three, six, and 12 month follow up studies, 47, 38, and 32 workers from the baseline sample of 68 completed a telephone survey and provided at least one saliva cotinine specimen. INTERVENTION: The smoke-free law went into effect 24 July 2003. MAIN OUTCOME MEASURES: Self reported sensory and respiratory symptoms and exposure to secondhand smoke; self administered saliva cotinine specimens. Analyses were limited to subjects in all four study periods who completed a telephone survey and provided at least one saliva cotinine specimen. RESULTS: All analyses were limited to participants who completed both an interview and a saliva specimen for all waves of data collection (n = 30) and who had cotinine concentrations < or = 15 ng/ml (n = 24). Hours of exposure to secondhand smoke in hospitality jobs decreased from 12.1 hours (95% confidence interval (CI) 8.0 to 16.3 hours) to 0.2 hours (95% CI -0.1 to 0.5 hours) (p < 0.01) and saliva cotinine concentration decreased from 3.6 ng/ml (95% CI 2.6 to 4.7 ng/ml) to 0.8 ng/ml (95% CI 0.4 to 1.2 ng/ml) (p < 0.01) from baseline to the 12 month follow up. The prevalence of workers reporting sensory symptoms declined from 88% (95% CI 66% to 96%) to 38% (95% CI 20% to 59%) (p < 0.01); there was no change in the overall prevalence of upper respiratory symptoms (p < 0.16). CONCLUSION: New York's smoke-free law had its intended effect of protecting hospitality workers from exposure to secondhand smoke within three months of implementation. One year after implementation, the results suggest continued compliance with the law.

RESUMO

BACKGROUND: The magnitude of the startle eyeblink response is reduced if the startle eliciting stimulus is shortly preceded by another stimulus. There is evidence that schizophrenia patients exhibit impairments in this so-called prepulse inhibition. Our study investigated whether prepulse inhibition is affected by neuroleptic drug treatment as is suggested by animal research. METHODS: Prepulse inhibition was tested in five unmedicated and 20 medicated inpatients with schizophrenia, and 12 normal controls. RESULTS: The unmedicated schizophrenia patients showed a strong impairment of sensorimotor gating as indexed by the absence of prepulse inhibition. By contrast, the medicated patients showed a pronounced prepulse inhibition that did not differ from that of the normal controls. There was a substantial covariation between the rated severity of the positive syndrome and the amount of prepulse inhibition--i.e., the patients whose positive symptoms were rated as more severe showed less prepulse inhibition. CONCLUSIONS: These data suggest that the impaired sensorimotor gating of schizophrenia patients is not a stable vulnerability indicator, but may rather be related to the positive syndrome and may be improved by treatments with neuroleptic medication.

We have studied the expression of the nuclear orphan receptor GCNF (germ cell nuclear factor) on the mRNA and protein level in pubertal and adult mouse testes. We show by Northern and Western blot analyses and by in situ hybridization that GCNF is expressed in spermatocytes and round spermatids of adult mouse testis suggesting that GCNF may be a transcriptional regulator of spermatogenesis. Since the GCNF protein is accumulated in the XY body of late pachytene spermatocytes, it may be involved in transcriptional inactivation of sex chromosomes.
