RESUMEN

BACKGROUND AND AIMS: Adverse pregnancy outcomes (APO) have been related to increased cardiovascular (CV) risk and mortality in later life. Underlying pathomechanisms for the development of CV disease in these women are not yet fully understood. In this study, we aimed to investigate the relationship between APO and individual CV risk profiles in later life. METHODS: We used cross-sectional data from 10,000 participants enrolled in the Hamburg City Health Study (HCHS). We analysed self-reported APO, CV risk factors and health status, including biomarkers, electrocardiogram, echocardiography and vascular ultrasound. To examine associations, Wilcoxon rank sum test and Pearson's χ2-test were performed. Multivariable-adjusted regression models were calculated to determine associations. RESULTS: N = 1970 women who reported pregnancies were included. Median age was 63 years, 8.7 % reported gestational hypertension (gHTN), 18 % excessive weight gain and 2.4 % gestational diabetes. Ten percent had delivered newborns with birth weight <2.5 kg, 14 % newborns with birth weight >4 kg. In multivariable-adjusted models, significant associations between APO, CV risk profiles and cardiac remodeling were identified. gHTN correlated with higher body mass index (BMI) (Beta 1.68, CI 95 % 0.86-2.50; p < 0.001), hypertension (OR 4.58, CI 95 % 2.79-7.86; p < 0.001), left ventricular remodeling (e.g. left ventricular mass index (Beta 4.46, CI 95 % 1.05-7.87; p = 0.010)) and myocardial infarction (OR 3.27, CI 95 % 0.94-10.07; p = 0.046). CONCLUSIONS: In this population-based sample, APO were associated with CV risk profiles and cardiac remodeling in later life, suggesting early manifestations of future CV risk during pregnancy. Prospective data is needed for individual risk stratification in women with APO.

RESUMEN

BACKGROUND: Poor oral and dental health due to oral dysbiosis during pregnancy increases the risk for negative pregnancy outcomes. Communicating the importance of oral health is therefore essential in reducing the risk of adverse pregnancy outcomes. Professional guidance could substantially support women's positive perception of their own competence. Information on oral health should be provided by healthcare professionals such as midwives, obstetricians and dentists. The aim of this study was to assess the needs, wishes and preferences of pregnant women in Germany, regarding interprofessional collaboration and guidance on oral health during pregnancy. METHODS: Sources of information, preferences regarding information supply as well as the need for interprofessional collaboration of involved healthcare professions were investigated in six online focus groups with pregnant women. In addition, three expert interviews with a midwife, an obstetrician and a dentist were conducted. The focus groups and interviews were analysed using qualitative content analysis according to Kuckartz. RESULTS: 25 pregnant women participated in focus groups. Pregnant women in all trimesters, aged 23 to 38 years, were included. Many women did not receive any or received insufficient information on oral health during pregnancy and wished for more consistent and written information from all involved healthcare providers. The extent of oral health counselling women received, heavily relied on their personal initiative and many would have appreciated learning about the scientific connection between oral health and pregnancy outcomes. An overall uncertainty about the timing and safety of a dental visit during pregnancy was identified. Interviews with experts provided additional insights into the working conditions of the involved healthcare professionals in counselling and emphasised the need for improved training on oral health during pregnancy in their respective professional education as well as thematic billing options in relation to this topic. CONCLUSION: Guidance of women on oral health during pregnancy appears to be insufficient. Providing information adapted to the needs, wishes and preferences of women during pregnancy as well as the implementation of this topic in the education of involved healthcare professionals could contribute to an improved prenatal care for pregnant women and subsequently a reduced risk of negative pregnancy outcomes.

RESUMEN

INTRODUCTION: Risk stratification scores such as the European Systematic COronary Risk Evaluation (SCORE) are used to guide individuals on cardiovascular disease (CVD) prevention. Adding high-sensitivity troponin I (hsTnI) to such risk scores has the potential to improve accuracy of CVD prediction. We investigated how applying hsTnI in addition to SCORE may impact management, outcome, and cost-effectiveness. METHODS: Characteristics of 72,190 apparently healthy individuals from the Biomarker for Cardiovascular Risk Assessment in Europe (BiomarCaRE) project were included into a discrete-event simulation comparing two strategies for assessing CVD risk. The standard strategy reflecting current practice employed SCORE (SCORE); the alternative strategy involved adding hsTnI information for further stratifying SCORE risk categories (S-SCORE). Individuals were followed over ten years from baseline examination to CVD event, death or end of follow-up. The model tracked the occurrence of events and calculated direct costs of screening, prevention, and treatment from a European health system perspective. Cost-effectiveness was expressed as incremental cost-effectiveness ratio (ICER) in € per quality-adjusted life year (QALYs) gained during 10 years of follow-up. Outputs were validated against observed rates, and results were tested in deterministic and probabilistic sensitivity analyses. RESULTS: S-SCORE yielded a change in management for 10.0% of individuals, and a reduction in CVD events (4.85% vs. 5.38%, p<0.001) and mortality (6.80% vs. 7.04%, p<0.001). S-SCORE led to 23 (95%CI: 20-26) additional event-free years and 7 (95%CI: 5-9) additional QALYs per 1,000 subjects screened, and resulted in a relative risk reduction for CVD of 9.9% (95%CI: 7.3-13.5%) with a number needed to screen to prevent one event of 183 (95%CI: 172 to 203). S-SCORE increased costs per subject by 187€ (95%CI: 177 € to 196 €), leading to an ICER of 27,440€/QALY gained. Sensitivity analysis was performed with eligibility for treatment being the most sensitive. CONCLUSION: Adding a person's hsTnI value to SCORE can impact clinical decision making and eventually improves QALYs and is cost-effective compared to CVD prevention strategies using SCORE alone. Stratifying SCORE risk classes for hsTnI would likely offer cost-effective alternatives, particularly when targeting higher risk groups.

RESUMEN

OBJECTIVE: The main goals of our study were (I) the investigation of expectations and preferences as well as (II) the determination of needs of women in regard to midwifery care. DESIGN: Descriptive phenomenology was used to investigate the ways in which women experienced childbirth and early parenthood. A descriptive qualitative research design was chosen, using focus groups. SETTING: ix online focus groups were carried out with 19 women for this part of the Midwifery Care (MiCa) study, mainly from the north of Germany. PARTICIPANTS: Women shortly after birth, in puerperium and the first year after childbirth were recruited in Germany. A purposeful strategy according to maximum variation sampling was applied to reach diversity in the sample regarding age and previous children. Data were analysed using qualitative content analysis, according to Mayring, with support of the qualitative data analysis software MAXQDA 2022. FINDINGS: Six main categories were derived for both childbirth and early parenthood: (a) involvement of family, (b) need for information, (c) physical and psychological aspects and (d) orientation in the healthcare system. In each group, one main category about provision of healthcare was developed: (e) care around childbirth and (f) midwifery care in early parenthood. Women attached great importance to the communication with midwives and favoured the involvement of their partners in the childbirth process and during parenting. Based on different experiences and inconsistency of information, women would prefer consistency in staff and communication as well as standardised information. CONCLUSIONS: From the user's perspective, midwifery care is crucial during childbirth and the child's first year of life. Current health care during and after childbirth and early parenthood lacks individualised care models, emotional support, adequate and professional communication between different health care providers, and consistency in midwifery care. Our findings should be translated into health care delivery with effective interprofessional teamwork within the continuity of midwifery care. Further quantitative research should analyse the individual healthcare situations of women in the reproductive phase of their life as well as of the applied healthcare models in order to personalise care and to improve healthcare quality.

RESUMEN

Midwifery services play an important role in healthcare provision, birth preparation and prevention. Knowledge on women's expectations, preferences and needs regarding midwifery care is crucial not only for clinical care during preconception and pregnancy and research, but also for educational purposes. This descriptive qualitative study aimed to investigate the expectations, preferences and the needs of women concerning midwifery care in Germany. Experienced researcher team conducted interviews with women who have the desire to get pregnant and online focus groups with women in early and late pregnancy. A purposeful recruitment strategy with maximum variation sampling was applied to reach diversity in the sample regarding age, previous children and socioeconomic background. A total of 26 women participated. In the qualitative content analysis according to Mayring, seven main categories were developed for both preconceptional phase and pregnancy: (a) care by midwife, (b) care by obstetrician, (c) involvement of family, (d) need for information, (e) physical aspects, (f) psychological aspects and (g) orientation in healthcare system. One additional category referenced (h) organisation and bureaucracy in pregnant women. Women appreciated the personalised experience provided by midwives leading to trust and empowerment. Women's experiences with midwifery care varied. They reported contradictory information they received about services and care options. They valued interprofessional cooperation, continuity of care, structured information and personalised counselling. Midwives play an important role in healthcare provision, birth preparation and prevention. In order to depict the care situation quantitatively, to personalise care and to optimise healthcare models, a tool to assess the quality of healthcare and to evaluate women's needs and benefits of midwifery care will be developed based on the findings of this study. From the public health perspective, deficits in the German healthcare system concerning insufficient intra-sectoral communication, time pressure and low remuneration should be resolved in further research steps and policy action.

RESUMEN

BACKGROUND: A healthy nutrition in pregnancy supports maternal health and fetal development, decreasing the risk for adverse pregnancy outcomes. Guidance by prenatal care professionals can increase women's awareness regarding the importance of nutrition in pregnancy and thereby contribute to a reduced risk for adverse pregnancy outcomes. The aim of this study was to assess the needs, wishes and preferences of pregnant women regarding the interprofessional guidance on nutrition in pregnancy. METHODS: Using a qualitative approach and a purposive maximum variation sampling strategy, 25 pregnant women were recruited to participate in six semi-structured, guideline-oriented online focus groups. In addition, two semi-structured, guideline-oriented interviews, with a midwife and an obstetrician, were conducted. The focus groups and interviews were audio-recorded and transcribed. Transcripts were analysed using a systematic deductive-inductive approach to qualitative content analysis according to Kuckartz. RESULTS: Focus group participants covered diverse perspectives in terms of their age, different models of prenatal care as well as dietary forms from omnivorous to vegan. The majority of women perceived the guidance on nutrition during pregnancy as insufficient. Involved healthcare professionals, namely midwives and obstetricians, should provide more consistent information, especially to avoid uncertainties exacerbated by the internet and social media. There is a need for individual nutrition information regarding dietary supplements and the specifics of different dietary forms during pregnancy, such as a vegan diet. The majority of participants supported the integration of a free-of-charge professional nutrition counselling in prenatal care. Interviews with experts identified time pressure and the complexity of nutrition as a topic as the main obstacles in consultation settings. Both midwife and obstetrician emphasised the need for improved professional education on nutrition in pregnancy in their respective studies. CONCLUSION: Professional guidance for pregnant women on nutrition and uncertainties going along with certain forms of diet during pregnancy could alleviate the burden and overwhelming amount of web-based information. Additionally, information adapted to the needs, wishes and preferences of pregnant women would improve prenatal care through a more personalised approach. The quality of nutrition guidance in pregnancy should be improved by the implementation of this topic in the education of involved healthcare professionals.

RESUMEN

Dietary and social behaviour are non-medical factors that influence health outcomes. Non-communicable diseases are related to dietary patterns. To date, little is known about how social behaviour is associated with health-related dietary patterns, and, in particular, we lack information about the role of sex within this possible relation. Our cross-sectional study investigated associations between dietary patterns and social behaviour including personality traits (self-control, risk taking), political preferences (conservative, liberal, ecological, social) and altruism (willingness to donate, club membership, time discounting) in men and women. We performed sex-specific correlation analyses to investigate relationships between dietary patterns based on self-reported protocols from the Mediterranean Diet Adherence Screener (MEDAS) and the validated Healthy Eating Index (HEI) from the EPIC Study and a self-reported social behaviour questionnaire. In linear regression models, we analysed associations between dietary and social behaviour patterns. Sex differences were measured by interaction analysis for each social behaviour item. The study sample consisted of N = 102 low-risk individuals. The median age of the study participants was 62.4 (25th/75th percentile 53.6, 69.1) years, and 26.5% were women. Analyses showed that a lower HEI score was correlated with a higher BMI in both women and men. MEDAS and HEI showed a positive correlation with each other in men. In men, a higher MEDAS showed a positive correlation when they estimated their ability as high, with the same for self-control and preference for ecological politics and MEDAS. A weak negative correlation has been shown between men with a preference for conservative politics and MEDAS. HEI showed a positive significant correlation with age in men. Male participants without club membership scored significantly higher in the HEI compared to non-members. A negative correlation was shown for time discounting in men. Linear regression models showed positive associations between preferences for ecological-oriented politics and nutrition for both HEI and MEDAS. No sex interactions were observed. We faced a few limitations, such as a small sample size, particularly for women, and a limited age spectrum in a European cohort. However, assuming that individuals with a preference for ecological-oriented politics act ecologically responsibly, our findings indicate that ecological behaviour in low-risk individuals might determine, at least in part, a healthy diet. Furthermore, we observed dietary patterns such as higher alcohol consumption in men or higher intake of butter, margarine and cream in women that indicate that women and men may have different needs for nutritional improvement. Thus, further investigations are needed to better understand how social behaviour affects nutrition, which could help to improve health. Our findings have the potential to inform researchers and practitioners who investigate the nature of the relationship between social behaviour and dietary patterns to implement strategies to create first-stage changes in health behaviour for individuals with a low cardiovascular risk profile.

RESUMEN

BACKGROUND: Prostate cancer (PCa) is the most frequently diagnosed malignant tumor in men. The potential benefit of a healthy lifestyle contrasts sharply with the observed poor adherence to current international lifestyle guidelines. Thus, well-designed sustainable interventions of aftercare that can be translated into routine practice are highly recommended. The present pilot study aimed to evaluate the feasibility and acceptability of a multimodal lifestyle intervention program in PCa patients after radical prostatectomy (RP). METHODS: In a single-arm study, carried out at the Martini-Klinik of the University Medical Center Hamburg-Eppendorf, Germany, 59 eligible men with locally advanced PCa were recruited within 3-6 months after RP and assigned to a multimodal lifestyle program. The program consisted of 10 weekly 6-7 h course days, with a focus on dietary control, physical activity (per World Cancer Research Fund recommendations) and psychological support. Primary objectives were feasibility, acceptability, completion rate, and safety. In addition, changes in lifestyle, psychological well-being, clinical and laboratory values were assessed. The study was registered in the German Clinical Trials Register (No. DRK S00015288 [MARTINI-Lifestyle-cohort] [www.germanctr.de]). RESULTS: A high program acceptance was observed. Only three participants (5%) dropped out of the program prematurely. Personal feedback reflected appreciation for participation, personal gain through new knowledge and through the group experience. Without exception, all participants have taken part in follow-up examinations and no adverse events or incidents occurred. In addition, changes in lifestyle habits, clinical parameters and improved quality of life were detected. CONCLUSION: The MARTINI lifestyle program appears feasible and safe, and acceptance of the multimodal intervention was high among PCa patients. These encouraging results favor conducting a large multicenter trial to implement the program into routine practice and to evaluate the effectiveness of the intervention on survival and quality of life.

RESUMEN

This population-based cross-sectional cohort study investigated the association of the Mediterranean and DASH (Dietary Approach to Stop Hypertension) diet as well as supplement intake with gray-scale median (GSM) and the presence of carotid plaques comparing women and men. Low GSM is associated with plaque vulnerability. Ten thousand participants of the Hamburg City Health Study aged 45-74 underwent carotid ultrasound examination. We analyzed plaque presence in all participants plus GSM in those having plaques (n = 2163). Dietary patterns and supplement intake were assessed via a food frequency questionnaire. Multiple linear and logistic regression models were used to assess associations between dietary patterns, supplement intake and GSM plus plaque presence. Linear regressions showed an association between higher GSM and folate intake only in men (+9.12, 95% CI (1.37, 16.86), p = 0.021). High compared to intermediate adherence to the DASH diet was associated with higher odds for carotid plaques (OR = 1.18, 95% CI (1.02, 1.36), p = 0.027, adjusted). Odds for plaque presence were higher for men, older age, low education, hypertension, hyperlipidemia and smoking. In this study, the intake of most supplements, as well as DASH or Mediterranean diet, was not significantly associated with GSM for women or men. Future research is needed to clarify the influence, especially of the folate intake and DASH diet, on the presence and vulnerability of plaques.

RESUMEN

Understanding the inflammatory response in oral biofilm during pregnancy and its association with oral and maternal health is essential for identifying biomarker patterns that may serve as markers of pregnancy-related complications. We aimed to conduct a systematic review of the available literature to assess: (1) inflammatory responses in oral biofilm during pregnancy, (2) the association between inflammatory responses in oral biofilm during pregnancy and maternal, oral or systemic conditions, (3) changes in the response of inflammatory biomarkers found in the oral biofilm during different pregnancy stages, and (4) the value of other risk factors such as nutrition and lifestyle. PubMed, Web of Science and Cochrane Library were systematically searched from inception until April 2022. From 5441 records, 39 studies were included for qualitative assessment. The oral biofilm in pregnant women was associated with increased inflammatory biomarkers when compared to non-pregnant women. Levels of inflammatory biomarkers in the oral biofilm were found to be highest in pregnant women with systemic conditions. Increased inflammatory biomarkers in the oral biofilm were also associated with worse oral health outcomes. Given the importance of nutrition and lifestyle for pregnancy and oral health outcomes and the fact that these factors were largely excluded in the included studies, future research should consider a holistic view of the mother during pregnancy to capture physiological, hormonal, immunologic, and metabolic changes in the context of inflammatory responses.

RESUMEN

A relationship between lifestyle, diet, and atrial fibrillation (AF) remains unclear. Except for alcohol consumption, AF guidelines do not differentiate specific advice for this rhythm disorder. The aim of this study was to investigate the association between adherence to healthy dietary patterns and the presence of AF, among 104 low risk participants from the 1:1 matched case-control AFHRI (Atrial Fibrillation in High-Risk Individuals) study. Dietary data were obtained using a three-day food record. Adapted German versions of the validated 14-item Mediterranean Diet Adherence Screener (MEDAS) and the validated eight-item Healthy Eating Index (HEI) from the Epic Study served as the basis for data derivation. The median age of the study participants was 63.0 years, 73.1% were men. In multivariable adjusted binary logistic regression analyses, we found inverse associations between both dietary indices (MEDAS: Median = 3, HEI: Median = 54.9) and the presence of AF (odds ratio for MEDAS: 0.65, 95% confidence interval (CI): 0.47-0.91, odds ratio for HEI: 0.60, 95% CI 0.39-0.95). Further clinical studies are needed to confirm the extent to which high quality dietary patterns such as a Mediterranean diet influence the onset and natural history of AF, in order to provide dietary counselling.

RESUMEN

In this study we evaluated possible differences in metabolomic profiles of spent embryo culture media (SECM) of human embryos with distinct morphology, karyotype, and implantation outcomes. A total of 153 samples from embryos of patients undergoing in vitro fertilization (IVF) programs were collected and analyzed by HPLC-MS. Metabolomic profiling and statistical analysis revealed clear clustering of day five SECM from embryos with different morphological classes and karyotype. Profiling of day five SECM from embryos with different implantation outcomes showed 241 significantly changed molecular ions in SECM of successfully implanted embryos. Separate analysis of paired SECM samples on days three and five revealed 46 and 29 molecular signatures respectively, significantly differing in culture media of embryos with a successful outcome. Pathway enrichment analysis suggests certain amino acids, vitamins, and lipid metabolic pathways to be crucial for embryo implantation. Differences between embryos with distinct implantation potential are detectable on the third and fifth day of cultivation that may allow the application of culture medium analysis in different transfer protocols for both fresh and cryopreserved embryos. A combination of traditional morphological criteria with metabolic profiling of SECM may increase implantation rates in assisted reproductive technology programs as well as improve our knowledge of the human embryo metabolism in the early stages of development.

RESUMEN

Despite the improvements in biotechnological approaches and the selection of controlled ovarian hyperstimulation protocols, the resulting pregnancy rate from in vitro fertilization (IVF) protocols still does not exceed 30-40%. In this connection, there is an acute question of the development of a non-invasive, sensitive, and specific method for assessing the implantation potential of an embryo. A total of 110 subfertile couples were included in the study to undergo the IVF/ICSI program. Obtained embryos for transfer into the uterine cavity of patient cohort 1 (n = 60) and cohort 2 (n = 50) were excellent/good-quality blastocysts, and small noncoding RNA (sncRNA) content in the corresponding spent culture medium samples at the morula stage (n = 43) or at the blastocyst stage (n = 31) was analyzed by deep sequencing followed by qRT-PCR in real time. Two logistic regression models were developed to predict the implantation potential of the embryo with 100% sensitivity and 100% specificity: model 1 at the morula stage, using various combinations of hsa_piR_022258, hsa-let-7i-5p, hsa_piR_000765, hsa_piR_015249, hsa_piR_019122, and hsa_piR_008112, and model 2 at the blastocyst stage, using various combinations of hsa_piR_020497, hsa_piR_008113, hsa-miR-381-3p, hsa_piR_022258, and hsa-let-7a-5p. Protein products of sncRNA potential target genes participate in the selective turnover of proteins through the ubiquitination system and in the organization of the various cell cytoskeleton and nucleoskeleton structures, regulating the activity of the Hippo signaling pathway, which determines the fate specification of the blastomers.

RESUMEN

BACKGROUND: Biomarkers may contribute to improved cardiovascular risk estimation. Glycated hemoglobin A1c (HbA1c) is used to monitor the quality of diabetes treatment. Its strength of association with cardiovascular outcomes in the general population remains uncertain. This study aims to assess the association of HbA1c with cardiovascular outcomes in the general population. METHODS: Data from six prospective population-based cohort studies across Europe comprising 36,180 participants were analyzed. HbA1c was evaluated in conjunction with classical cardiovascular risk factors (CVRFs) for association with cardiovascular mortality, cardiovascular disease (CVD) incidence, and overall mortality in subjects without diabetes (N = 32,496) and with diabetes (N = 3684). RESULTS: Kaplan-Meier curves showed higher event rates with increasing HbA1c levels (log-rank-test: p < 0.001). Cox regression analysis revealed significant associations between HbA1c (in mmol/mol) in the total study population and the examined outcomes. Thus, a hazard ratio (HR) of 1.16 (95% confidence interval (CI) 1.02-1.31, p = 0.02) for cardiovascular mortality, 1.13 (95% CI 1.03-1.24, p = 0.01) for CVD incidence, and 1.09 (95% CI 1.02-1.17, p = 0.01) for overall mortality was observed per 10 mmol/mol increase in HbA1c. The association with CVD incidence and overall mortality was also observed in study participants without diabetes with increased HbA1c levels (HR 1.12; 95% CI 1.01-1.25, p = 0.04) and HR 1.10; 95% CI 1.01-1.20, p = 0.02) respectively. HbA1c cut-off values of 39.9 mmol/mol (5.8%), 36.6 mmol/mol (5.5%), and 38.8 mmol/mol (5.7%) for cardiovascular mortality, CVD incidence, and overall mortality, showed also an increased risk. CONCLUSIONS: HbA1c is independently associated with cardiovascular mortality, overall mortality and cardiovascular disease in the general European population. A mostly monotonically increasing relationship was observed between HbA1c levels and outcomes. Elevated HbA1c levels were associated with cardiovascular disease incidence and overall mortality in participants without diabetes underlining the importance of HbA1c levels in the overall population.

RESUMEN

Working conditions in the care sector, especially under the increased strain during COVID-19, make it difficult for outpatient caregivers to adhere to health-promoting behaviours. Research on workplace health promotion (WHP) and COVID-19 support measures in outpatient care services is limited. The aim of this pilot study was to characterise the current situation of WHP and COVID-19 support measures in outpatient care services and to explore how to offer WHP support measures targeted for a specific group. A web-based cross-sectional survey was conducted with outpatient caregivers (N = 171) in northern Germany. The results showed that 60.2% of the study participants were offered WHP support measures, with significantly higher work engagement when WHP support measures were available (Z = 4279.50, p < 0.01) and that 77.2% received specific support from their employer during the COVID-19 pandemic. Although spending a break in a break room was significantly associated with longer breaks as compared with being in a car (Z = 39.10, padj. = 0.01), a break room was neither available in all outpatient care services, nor did it appear to be feasible. Overall, WHP in outpatient care services is insufficiently covered. In order to be able to offer WHP support measures that are targeted to outpatient caregivers, cooperation among local care services, feasibility, and digital measures should be examined.

RESUMEN

The rate of hydrolysis-condensation reaction of phenyltrichlorosilane in water-acetone solutions and the product yields were shown to significantly depend on the concentration of HCl (CHCl) in the solutions. The main product of the reaction was all-cis-(tetrahydroxy)(tetraphenyl)cyclotetrasiloxane. This was different from the earlier published results of analogous reactions of m-tolylSiCl3, m-ClPhSiCl3, and α-naphtylSiCl, in which some products of other types were formed. For example, trans-1,1,3,3-tetrahydroxy-1,3-di-α-naphtyldisiloxane was obtained in the case of α-naphtylSiCl3. All-cis-(tetrahydroxy)(tetraphenyl)cyclotetrasiloxane was treated in acetone with HCl to give the other three geometric isomers (cis-cis-trans-, cis-trans-, and all-trans-). The thermal self-condensation of these four isomers under "pseudo"-equilibrium conditions (under atmospheric pressure) was investigated in different solvents, in quartz or molybdenum glass flasks. The compositions of the products were monitored by APCI-MS and 29Si NMR spectroscopy. It was shown that all-cis- and cis-cis-trans-isomers in toluene or anisole mostly gave the cage-like Ph-T8,10,12,14 and uncompleted cage-like Ph-T10,12OSi(HO)Ph compounds. In contrast to these two isomers, the cis-trans-isomer in toluene mainly formed dimers with the loss of one or two molecules of water. However, in acetonitrile, significant amounts of Ph-T10,12 and Ph-T10,12OSi(HO)Ph species were formed along with the dimers. All-trans-isomer did not enter into the reaction at all.

RESUMEN

As part of the optimization of assisted reproductive technology programs, the aim of the study was to identify key small noncoding RNA (sncRNA) molecules that participate in maternal-to-zygotic transition and determine development potential and competence to form a healthy fetus. Small RNA deep sequencing followed by quantitative real-time RT-PCR was used to profile sncRNAs in 50 samples of spent culture medium from morula with different development potentials (no potential (degradation/developmental arrest), low potential (poor-quality blastocyst), and high potential (good/excellent quality blastocyst capable of implanting and leading to live birth)) obtained from 27 subfertile couples who underwent in vitro fertilization. We have shown that the quality of embryos at the morula stage is determined by secretion/uptake rates of certain sets of piRNAs and miRNAs, namely hsa_piR_011291, hsa_piR_019122, hsa_piR_001311, hsa_piR_015026, hsa_piR_015462, hsa_piR_016735, hsa_piR_019675, hsa_piR_020381, hsa_piR_020485, hsa_piR_004880, hsa_piR_000807, hsa-let-7b-5p, and hsa-let-7i-5p. Predicted gene targets of these sncRNAs included those globally decreased at the 8-cell-morula-blastocyst stage and critical to early embryo development. We show new original data on sncRNA profiling in spent culture medium from morula with different development potential. Our findings provide a view of a more complex network that controls human embryogenesis at the pre-implantation stage. Further research is required using reporter analysis to experimentally confirm interactions between identified sncRNA/gene target pairs.

RESUMEN

OBJECTIVES: The aims of this study were to characterize the association of high-sensitivity cardiac troponin I (hs-cTnI) with heart failure (HF), to determine its predictive value beyond classical cardiovascular risk factors (CVRFs) and N-terminal pro-B-type natriuretic peptide, and to derive a relevant cutoff for potential clinical application. BACKGROUND: HF is an important contributor to the overall burden of cardiovascular disease. Early identification of individuals at risk could be beneficial for preventive therapies. METHODS: Based on the Biomarker for Cardiovascular Risk Assessment in Europe consortium, we analyzed individual-level data from 4 prospective population-based cohort studies including 48,455 individuals. Participants with myocardial infarction, HF, and stroke at baseline were excluded. We investigated the value of adding hs-cTnI to CVRFs and N-terminal pro-B-type natriuretic peptide using Cox proportional hazards survival models and for prediction by calculating C-statistics and Brier score. RESULTS: The median age of the study population was 51 years, and the median follow-up time for occurrence of HF was 6.61 years. Cox regression models adjusted for age, sex, and CVRFs revealed a significant association of hs-cTnI with incident HF (hazard ratio: 1.42 per log [ng/l] unit change [95% confidence interval: 1.31 to 1.53]). The best predictive value was achieved in the model with CVRFs (base model) and both biomarkers (C-index = 0.862; 95% confidence interval: 0.841 to 0.882). Optimal hs-cTnI cutoff values of 2.6 ng/l for women and 4.2 ng/l for men were derived for selecting individuals at risk. CONCLUSIONS: In this large dataset from the general population, hs-cTnI could show its independence for the prognosis of HF.

RESUMEN

The hydrolysis-condensation reactions of m-tolyl, m-chlorophenyl, and α-naphtyl-trichlorsilanes, (1, 2, and 3, respectively) in water-acetone solutions were examined for how they were influenced by the change in the concentration of HCl (CHCl). The composition of the products was monitored by 29Si NMR spectroscopy and atmospheric pressure chemical ionization mass spectrometry (APCI-MS). The acidity of the medium was shown to affect the yields of the products, and so, what products were formed. For 3, e.g., APCI-MS showed peaks of α-naphtyl-T8 and α-naphtyl-T10 as the most abundant in the spectra taken after 48 and 240 h for the reaction conducted at CHCl = 0.037 mol L-1. Unlike this, at CHCl = 0.15 mol L-1, those peaks were of [α-naphtyl(HO)2SiO]2(α-naphtyl)(HO)Si and/or [α-naphtyl(HO)Si]3, [α-naphtyl(HO)Si]4,5, and α-naphtyl-T8 after 192 h. However, at both CHCl values, the main product (and an intermediate) after 24 h was trans-1,1,3,3-tetrahydroxy-1,3-di-α-naphtyldisiloxane. It was isolated and its structure established by 1H-, 29Si-NMR, and X-ray powder diffraction.
