Association of response time and intermittent hypoxemia in extremely preterm infants.

AIM: To determine the relationship between medical staff's response time (RT) to oxygen saturation (SpO2 ) below 80% and the associated time from tactile intervention until SpO2 normalisation (CT). METHODS: Time-lapse video and continuous SpO2 were recorded for six consecutive 24 h periods. Regression analyses of RT and SpO2 in association with postmenstrual age (PMA), weight, infant sex and frequency of intermittent hypoxemia (IH). RESULTS: Five hundred and twelve hypoxemia episodes received tactile intervention in 20 extremely preterm infants (gestational age ≤28 weeks, birthweight <1500 g). Median RT was 20.5 s (IQR 16.63-25.50). RT increased with increased IH frequency (p = 0.023) independently of PMA and weight. SpO2 decreased by 3.7% with every 10 s RT (p = 0.039). Time until SpO2 normalisation was strongly associated with RT (ß = 0.58, p = 0.042). The association was amplified by lower PMA (p = 0.043). Female preterm infants experienced longer RT than males (p = 0.027). Because the total length of an IH is the sum of RT and CT, preterm infants with low PMA can reach a critical hypoxemia duration of >60 s, even with short RT. CONCLUSION: The RT is a critical factor that affects the overall time of IH treatments and the depth of desaturation. The consequences of a prolonged RT are worse for more immature preterm infants.

Multiplex genetic cancer testing identifies pathogenic mutations in TP53 and CDH1 in a patient with bilateral breast and endometrial adenocarcinoma.

BACKGROUND: Germline genetic testing for familial cancer syndromes is usually performed serially for the most likely genetic causes. In recent years the way genetic testing carried out has changed, as next generation sequencing now allows the simultaneous testing of multiple susceptibility genes at low costs. CASE PRESENTATION: Here, we present a female with bilateral breast cancer and endometrial adenocarcinoma. After simultaneous sequencing of 150 genes (890 kb) associated with hereditary cancer we identified pathogenic mutations in two high-penetrance genes, i.e. TP53 and CDH1 that would most likely not have been elucidated by serial screening of candidate genes. CONCLUSION: As the two mutated genes are located on different chromosomes and cause different cancer syndromes these findings had a tremendous impact not only on genetic counseling of the index patient and her family but also on subsequent surveillance strategies.

The malleability of gender stereotypes: influence of population size on perceptions of men and women in the past, present, and future.

Recent studies on the malleability of gender stereotypes show that they are flexible, dynamic structures that change with the passage of time. In a study, we examined perceptions about men and women of the past, present, and future in Spain and focused on the influence of an important demographic variable on these perceptions: the population size of people's location of residence. Results showed that people perceived an increase in similarity of men and women from the past to the present and from the present to the future. In less-populated locations, however, men and women were more gender stereotyped and, consequently, still perceived to be further from equality than those in more populated areas. We concluded that the study of dynamic gender stereotypes benefits from extensive research in populations that vary in their demographic characteristics and shows the importance of recent movements in rural areas supporting women's participation in the modernization process.

Do the media provide transparent health information? A cross-cultural comparison of public information about the HPV vaccine.

The media is a powerful tool for informing the public about health treatments. In particular, the Internet has gained importance as a widely valued source for health information for parents and adolescents. Nonetheless, traditional sources, such as newspapers, continue to report on health innovations. But do websites and newspaper reports provide balanced information? We performed a systematic media analysis to evaluate and compare media coverage of the human papillomavirus (HPV) vaccine on websites and in newspapers in Germany and Spain. We assessed to what extent the media provide complete (pros and cons), transparent (absolute instead of relative numbers), and correct information about the epidemiology and etiology of cervical cancer as well as the effectiveness and costs of the HPV vaccine. As a basis for comparison, a facts box containing current scientific evidence about cervical cancer and the HPV vaccine was developed. The media analysis included 61 websites and 141 newspaper articles in Germany, and 41 websites and 293 newspaper articles in Spain. Results show that 57% of German websites and 43% of German newspaper reports communicated correct estimates of epidemiological data, whereas in Spain 39% of the websites and 20% of the newspaper did so. While two thirds of Spanish websites explicitly mentioned causes of cervical cancer as well as spontaneous recovery, German websites communicated etiological information less frequently. Findings reveal that correct estimates about the vaccine's effectiveness were mentioned in 10% of German websites and 6% of German newspaper reports; none of the Spanish newspaper reports and 2% of Spanish websites reported effectiveness correctly. Only German websites (13%) explicitly referred to scientific uncertainty regarding the vaccine's evaluation. We conclude that the media lack balanced reporting on the dimensions completeness, transparency, and correctness. We propose standards for more balanced reporting on websites and in newspapers.

Causal beliefs and empirical evidence.

Causal beliefs often facilitate decision making. However, strong causal beliefs can also lead to neglect of relevant empirical evidence causing errors in risky decision making (e.g., medical, financial). We investigated the impact of pre-training and post-experience on the evaluation of empirical evidence in a two-alternative medical diagnostic task. Participants actively searched for information about two patients on the basis of four available cues. The first experiment indicated that pre-training can weaken the strong influence of causal beliefs reducing neglect of empirical evidence. The second experiment demonstrated that increasing amounts of empirical evidence can improve people's ability to decide in favor of a correct diagnosis. The current research converges with other recent work to clarify key mechanisms and boundary conditions shaping the influence of causal beliefs and empirical evidence in decisions and causal judgments.
