[Ab] Resumo:BACKGROUND: In Germany, regular immigrants and their descendants have legal and financial access to health care equal to the general citizenry. Nonetheless, some of their health outcomes are comparatively unfavorable, and that is only partially explained by their lower socioeconomic status (SES). The aim of this study was to assess whether this disparity exists also for obstetric and perinatal outcomes. METHODS: We compared obstetric and perinatal outcomes between immigrant women (first or second generation) and non-immigrant women, delivering at three maternity hospitals in Berlin, Germany, 2011-2012. Multivariable logistic regression analysis was used to assess immigrant status and other possible risk factors for the baby being delivered preterm, small for gestational age (SGA), or transferred to neonatal care. RESULTS: The final database retained 6702 women, of whom 53.1% were first- or second-generation immigrants. First-generation Turkish immigrant women had significantly lower odds of preterm birth (OR 0.37, P < 0.001), SGA (OR 0.60, P = 0.0079), and transfer of the newborn to neonatal care (OR 0.61, P = 0.0034). Second-generation immigrant women had significantly lower odds of preterm birth (OR 0.67, P = 0.0049) or transfer of the newborn to neonatal care (OR 0.76, P = 0.0312). Moreover, women with education below university level, age 35+, or smokers had higher odds for poor outcomes. CONCLUSIONS: This study provides strong evidence that health disparities for obstetric and perinatal health outcomes do not exist in immigrants relative to native Germans, but exist instead in women without post-secondary-level education compared to women with such education, regardless of ethnicity or migration history.

[Ab] Resumo:BACKGROUND: The last decades have seen great advances in the understanding, treatment, and prevention of cardiovascular disease (CVD). Although mortality rates due to CVD have declined significantly in the last decades, the burden of CVD is still high, particularly in older adults. This raises the question whether contemporary populations of older adults are experiencing better or worse objective as well as subjective health than earlier-born cohorts. The aim of this study was to examine differences in modifiable indicators of cardiovascular health (CVH), comparing data obtained 20 years apart in the Berlin Aging Study (BASE, 1990-93) and the Berlin Aging Study II (BASE-II, 2009-2014). METHODS: Serial cross-sectional analysis of 242 propensity-score-matched participants of BASE (born 1907-1922) and BASE-II (born 1925-1942). Body mass index (BMI), blood pressure, total cholesterol, glycated hemoglobin (HbA1c), diet, smoking and physical activity were operationalized according to the "Life's simple 7"(LS7) criteria of the American Heart Association. RESULTS: 121 matched pairs were identified based on age, sex, and education. In the later-born BASE-II sample, the mean LS7 score was significantly higher than in the earlier-born sample (7.8±1.8 vs. 6.4±2.1, p<0.001), indicating better CVH. In detail, diet, physical activity, smoking, cholesterol, and HbA1c were more favorable, whereas blood pressure was significantly higher in individuals from the later-born cohort. BMI did not differ significantly between the two matched samples. Notably, despite better CVH, later-born individuals (BASE-II) reported lower self-rated health, presumably because of higher health expectations. CONCLUSIONS: Overall, cardiovascular health was significantly better in the later-born cohort, but several notable exceptions exist.

[Ab] Resumo:BACKGROUND/AIM: Symptomatic hiatal hernia (HH) following resection for gastric or esophageal cancer is a potentially life-threatening event that may lead to emergent surgery. However, the incidence and risk factors of this complication remain unclear. PATIENTS AND METHODS: Data of patients who underwent resection for gastric or esophageal cancer between 2005 and 2012 were assessed and the incidence of symptomatic HH was evaluated. Factors associated with an increased risk for HH were investigated. RESULTS: Resection of gastric or esophageal cancer was performed in 471 patients. The primary tumor was located in the stomach, cardia and esophagus in 36%, 24%, and 40% of patients, respectively. The incidence of symptomatic HH was 2.8% (n=13). All patients underwent surgical hernia repair, 8 patients (61.5%) required emergent procedure, and 3 patients (23%) underwent bowel resection. Morbidity and mortality after HH repair was 38% and 8%, respectively. Factors associated with increased risk for symptomatic HH included Body-Mass-Index (median BMI with HH 27 (23-35) vs. BMI without HH 25 (15-51), p=0.043), diabetes (HH rate: with diabetes, 6.3% vs. without diabetes, 2%, p=0.034), tumor location (HH rate: stomach, 1.2% vs. esophagus, 1.1% vs. cardia, 7.9%, p=0.001), and resection type (HH rate: total/subtotal gastrectomy, 0.7% vs. transthoracic esophagectomy, 2.7% vs. extended gastrectomy, 6.1%, p=0.038). CONCLUSION: HH is a major adverse event after resection for gastric or esophageal cancer especially among patients undergoing extended gastrectomy for cardia cancer requiring a high rate of repeat surgery. Therefore, intensive follow-up examinations for high-risk patients and early diagnosis of asymptomatic patients are essential for selecting patients for elective surgery to avoid unpredictable emergent events with high morbidity and mortality.

[Ab] Resumo:PURPOSE: To compare finish times across WMM races for Boston, London, Berlin, Chicago and New York Marathons. METHODS: Race times of the top 10 male and 10 female finishers were analyzed from 2005 to 2014 using the high-performance mixed linear model procedure in the Statistical Analysis System. Venue-to-venue comparisons, as well as comparisons between Boston and other WMM races, with and without factors of temperature, humidity and altitude change were examined. RESULTS: Performance from 2005 to 2014 in the WMM races was found to improve at a rate of ~1% each 7 years. Despite its higher variability, comparison between Boston's estimated mean finishing time and all other venues revealed moderate positive differences, indicating the Boston event to be typically slower than other venues. CONCLUSIONS: Across the 10-year study period, performance times improved ~1% each 7 years for both genders for the WMM, with the Boston Marathon being slower on average than other WMM venues. Weather rather than course metrics appeared to impact performance times most.

[Ab] Resumo:BACKGROUND: Since the late 1950's, a steadily increasing immigrant population in Germany is resulting in a subpopulation of aging immigrants. The German health care system needs to adjust its services-linguistically, culturally, and medically-for this subpopulation of patients. Immigrants make up over 20% of the population in Germany, yet the majority receive inadequate medical care. As many of the labor immigrants of the 1960s and 1970s are in need of hospice and palliative care (HPC), little is known about this specialized care for immigrants. This epidemiological study presents utilization of HPC facilities in Berlin with a focus on different immigrant groups. METHODS: A validated questionnaire was used to collect data from patients at 34 HPC institutions in Berlin over 20 months. All newly admitted patients were recruited. Anonymized data were coded and analyzed by using SPSS and compared with the population statistics of Berlin. RESULTS: 4118 questionnaires were completed and included in the analysis. At 11.4% the proportion of immigrants accessing HPC was significantly (p<0,001) below their proportion in the general Berlin population. This difference was especially seen in the age groups of 51-60 (21.46% immigrants in Berlin population, 17.7% immigrants in HPC population) and 61-70 years (16,9% vs. 13,1%). The largest ethnic groups are Turks, Russians, and Poles, with a different weighting than in the general population: Turkish immigrants were 24% of all Berlin immigrants, but only 13.6% of the study immigrant population (OR: 0.23, 95%CI: 0.18-0.29, p<0.001). Russian and Polish immigrants account for 5.6% and 9.2% in the population, but 11.5% and 24.8% in the study population respectively (Russian: OR 0.88, 95%CI: 0.66-1.16; Polish: OR 1.17, 95%CI: 0.97-1.42). Palliative care wards (PC) were used most often (16.7% immigrants of all PC patients); outpatient hospice services were used least often by immigrants (11.4%). Median age at first admission to HPC was younger in immigrants than non-immigrants: 61-70 vs. 71-80, p = 0.03. CONCLUSIONS: Immigrants are underrepresented in Berlin´s HPC and immigrants on average make use of care at a younger age than non-immigrants. In this regard, Turkish immigrants in particular have the poorest utilization of HPC. These results should prompt research on Turkish immigrants, regarding access barriers, since they represent the largest immigrant group. This may be due to a lack of cultural sensitivity of the care-providers and a lack of knowledge about HPC among immigrants. In the comparison of the kinds of institutions, immigrants are less likely to access outpatient hospice services compared to PC. Apparently, PC appear to be a smaller hurdle for utilization. These results show a non-existent, but oft-cited "healthy immigrant effect" of the first generation of work immigrants, now entering old age. These findings correspond with studies suggesting increased health concerns in immigrants. Focused research is needed to promote efforts in providing adequate and fair access to HPC for all people in Berlin.

[Ab] Resumo:Steel components are typically treated with anti-corrosion coatings like epoxy or polyurethane resins to protect the integrity and functioning of steel. Such resins may contain substances, such as bisphenol A (BPA), that have caused concern in a human and environmental toxicological context. We investigated the release of toxicity from four anti-corrosion coatings used in hydraulic and civil engineering. Resins were applied onto glass plates and leachate samples produced by horizontally shaking the plates in water for 7 days. Two experiments were conducted, one with a 1 day and one with a 7 day curing period. Using a suite of bioassays, we tested samples for: agonistic and antagonistic effects on various mammalian nuclear receptors; inhibition of photosynthesis and growth in algae; inhibition of bacterial bioluminescence; and inhibition of water flea reproduction. Concentrations of BPA, bisphenol F and various BPA transformation products were determined by chemical analysis (LC-MS/MS). Bioassay results were evaluated using a scheme developed by DIBt (Centre of Competence for Construction, Berlin, Germany). Three products induced responses in one or more of the measured endpoints and toxicity profiles varied markedly in intensity across products. One product released high amounts of BPA which was associated with effects on nuclear receptor transactivation, requiring a more than 700-fold dilution for effect induction to fall below 20%. The same product was also the most toxic to water flea reproduction, requiring ca. 70-fold dilution for effects to fall below 20%. Another product was highly toxic in terms of bacterial bioluminescence, particularly after a shorter curing time, requiring a ca. 1'300-fold dilution for effects to fall below 20%. The third product required a 22-fold dilution for inhibition of water flea reproduction to drop below 20%. Results show that anti-corrosion coatings based on epoxy resins can be a source of toxicity to the aquatic environment. The fact that some products are more toxic than others highlights opportunities for the development of low risk formulations and products with better environmental performance. Finally, the DIBt scheme provides a useful starting point to develop further ecotoxicity guidelines for testing and data evaluation of leachates from construction materials.

[Ti] Título:N-acetyltransferase 1*10 genotype in bladder cancer patients.

[Ab] Resumo:In a large bladder cancer study in the greater Berlin area with 425 cases and 343 controls, the haplotype N-acetyltransferase 1*10 (NAT1*10) was associated with a decreased bladder cancer risk. In a recently published meta-analysis, results of the studies were found to be inconclusive. Therefore, the aim of this study was to investigate the frequency of NAT1*10 in bladder cancer patients and controls recruited in an area without industries reported to be associated with increased bladder cancer risk. Rs1057126 (1088 T > A) and rs15561 (1095 C > A) were determined in 412 bladder cancer patients and 415 controls without a known history of malignancies. With these two single-nucleotide polymorphisms (SNP), it was possible to distinguish between NAT1*4 (wild type), NAT1*3 (1095 C > A), and NAT1*10 (1088 T > A, 1095C > A). The frequencies of the determined NAT1 haplotypes did not differ markedly between cases and controls: NAT1*4: 74%, NAT1*3: 6%, NAT1*10: 20%. Bladder cancer risk was not significantly modulated by NAT1*10/*10 (OR 1.03, 95% CI 0.71-1.48) but was higher for NAT1*3/*3 genotypes (OR 2.05, 95% CI 1.32-3.21). In contrast to the Berlin study from 2001, data in present study demonstrated that NAT1*10 haplotype was not associated with a significantly decreased bladder cancer risk. This may be due to local effects in the greater Berlin area, particularly at the time of investigation. The findings of the present study are in agreement with observations of a recently published meta-analysis which also showed no relevant impact of NAT1*10 haplotype on bladder cancer risk. The impact of the rare NAT1*3/*3 genotype was significant but this may be attributed to rarity without major practical relevance.

[Ti] Título:Field campaign on sediment transport behaviour in a pressure main from pumping station to wastewater treatment plant in Berlin.

[Ab] Resumo:As part of the project KURAS, the Berliner Wasserbetriebe realized a field campaign in 2015 in order to increase the process knowledge regarding the behaviour of transported sediment in the pressure main leading from the pumpstation to the wastewater treatment plant. The field campaign was conducted because of a lack of knowledge about the general condition of the pressure main due to its bad accessibility and the suspicion of deposits caused by hydraulic underload. The practical evidence of the sediment transport performance of this part of the sewer system, dependent on different load cases, should present a basis for further analysis, for example regarding flushing measures. A positive side-effect of the investigation was the description of the amount of pollutants caused by different weather conditions in combined sewer systems and the alterations of the sewage composition due to biogenic processes during transport. The concept included the parallel sampling of the inflow at the pumpstation and the outflow at the end of the pressure main during different weather conditions. By calculating the inflow to the pressure main, as well as its outflow at different flow conditions, it was possible to draw conclusions in regard to the transport behaviour of sediment and the bioprocesses within an 8.5 km section of the pressure main. The results show clearly that the effects of sedimentation and remobilization depend on the flow conditions. The balance of the total suspended solids (TSS) load during daily variations in dry weather shows that the remobilization effect during the run-off peak is not able to compensate for the period of sedimentation happening during the low flow at night. Based on the data for dry weather, an average of 238 kg of TSS deposits in the pressure main remains per day. The remobilization of sediment occurs only due to the abruptly increased delivery rates caused by precipitation events. These high pollution loads lead to a sudden strain at the wastewater treatment plant. It was found that the sediment transport behaviour is characterized by sedimentation up to a flow velocity of 0.35 m/s, while remobilization effects occur above 0.5 m/s. The assumption of bad sediment transport performance in the pressure main was confirmed. Therefore, the results can be used as a basis for further analysis, for example regarding periodical flushing as a means of cleaning the pressure main. The findings, especially regarding the methods and processes, are transferable and can be applied to other pressure mains in combined sewer systems. Besides the outlined evaluation of the sediment transport behaviour of the pressure main, the collected data were used in the project to calibrate a sewer system model, including a water quality model for the catchment area, and as a contribution towards an early physically based sediment transport modelling in InfoWorks CS.

[Ab] Resumo:Most wildlife species are urban avoiders, but some became urban utilizers and dwellers successfully living in cities. Often, they are assumed to be attracted into urban areas by easily accessible and highly energetic anthropogenic food sources. We macroscopically analysed stomachs of 247 wild boar (Sus scrofa, hereafter WB) from urban areas of Berlin and from the surrounding rural areas. From the stomach contents we determined as predictors of food quality modulus of fineness (MOF,), percentage of acid insoluble ash (AIA) and macronutrients such as amount of energy and percentage of protein, fat, fibre and starch. We run linear mixed models to test: (1) differences in the proportion of landscape variables, (2) differences of nutrients consumed in urban vs. rural WB and (3) the impact of landscape variables on gathered nutrients. We found only few cases of anthropogenic food in the qualitative macroscopic analysis. We categorized the WB into five stomach content categories but found no significant difference in the frequency of those categories between urban and rural WB. The amount of energy was higher in stomachs of urban WB than in rural WB. The analysis of landscape variables revealed that the energy of urban WB increased with increasing percentage of sealing, while an increased human density resulted in poor food quality for urban and rural WB. Although the percentage of protein decreased in areas with a high percentage of coniferous forests, the food quality increased. High percentage of grassland decreased the percentage of consumed fat and starch and increased the percentage of fibre, while a high percentage of agricultural areas increased the percentage of consumed starch. Anthropogenic food such as garbage might serve as fallback food when access to natural resources is limited. We infer that urban WB forage abundant, natural resources in urban areas. Urban WB might use anthropogenic resources (e.g. garbage) if those are easier to exploit and more abundant than natural resources. This study shows that access to natural resources still is mandatory and drives the amount of protein, starch, fat or fibre in wild boar stomachs in urban as well as rural environments.
