- We report a practical and modular approach to obtain two different types of 17-membered ring macrocyclic compounds through an intramolecular Heck reaction. These macrocyclic compounds are functionalized, that is, they contain two contiguous stereogenic hydroxy functional groups and an amino acid moiety in the macrocyclic ring skeleton. The macrocycles were then screened against a zebrafish assay to determine the antiangiogenesis activity of these small molecules. Macrocyclic compound 2.2a was identified as a potent inhibitor at 2.5 M, whereas its acyclic precursor and the other related macrocyclic compounds did not show any effect.

- Research suggests that visual impressions of natural compared with urban environments facilitate recovery after psychological stress. To test whether auditory stimulation has similar effects, 40 subjects were exposed to sounds from nature or noisy environments after a stressful mental arithmetic task. Skin conductance level (SCL) was used to index sympathetic activation, and high frequency heart rate variability (HF HRV) was used to index parasympathetic activation. Although HF HRV showed no effects, SCL recovery tended to be faster during natural sound than noisy environments. These results suggest that nature sounds facilitate recovery from sympathetic activation after a psychological stressor.

- Objectives: A considerable increase in social inequalities in mortality was observed in Eastern Europe during the post-communist transition. This study evaluated the contribution of avoidable causes of death to the difference in life expectancy between Estonians and non-Estonians in Estonia. Study design: Descriptive study. Methods: Temporary life expectancy (TLE) was calculated for Estonian and non-Estonian men and women aged 0-74 years in 2005-2007. The ethnic TLE gap was decomposed by age and cause of death (classified as preventable or treatable). Results: The TLE of non-Estonian men was 3.53 years less than that of Estonian men, and the TLE of non-Estonian women was 1.36 years less than that of Estonian women. Preventable causes of death contributed 2.19 years to the gap for men and 0.78 years to the gap for women, while treatable causes contributed 0.67 and 0.33 years, respectively. Cardiorespiratory conditions were the major treatable causes of death, with ischaemic heart disease alone contributing 0.29 and 0.08 years to the gap for men and women, respectively. Conditions related to alcohol and substance use represented the largest proportion of preventable causes of death. Conclusions: Inequalities in health behaviours underlie the ethnic TLE gap in Estonia, rather than inequalities in access to health care or the quality of health care. Public health interventions should prioritize primary prevention aimed at alcohol and substance use, and should be implemented in conjunction with wider social policy measures

- Objective To investigate potential violations of patient confidentiality or other breaches of medical ethics committed by physicians and medical students active on the social networking site Twitter.Design Population-based cross-sectional observational study.Setting The social networking site Twitter (Swedish-speaking users, n=298819).Population Physicians and medical students (Swedish-speaking users, n=237) active on the social networking site Twitter between July 2007 and March 2012.Main outcome measure Postings that reflect unprofessional behaviour and ethical breaches among physicians and medical students.Results In all, 237 Twitter accounts were established as held by physicians and medical students and a total of 13 780 tweets were analysed by content. In all, 276 (1.9%) tweets were labelled as ‘unprofessional’. Among these, 26 (0.2%) tweets written by 15 (6.3%) physicians and medical students included information that could violate patient privacy. No information on the personal ID number or names was disclosed, but parts of the patient documentation or otherwise specific indicatory information on patients were found. Unprofessional tweets were more common among users writing under a pseudonym and among medical students.Conclusions In this study of physicians and medical students on Twitter, we observed potential violations of patient privacy and other breaches of medical ethics. Our findings underline that every physician and medical student has to consider his or her presence on social networking sites. It remains to be investigated if the introduction of social networking site guidelines for medical professionals will improve awareness.

- The corticotropin-releasing hormone (CRH) family consists of four aralogous genes, CRH and urocortins (UCNs) 1, 2, and 3. In a previous tudy, we analyzed CRH in the teleost model organism zebrafish and its ranscript distribution in the embryonic brain. Here, we describe ull-length cDNAs encoding urotensin 1 (UTS1), the teleost UCN1 rtholog, and UCN3 of zebrafish. Major expression sites of uts1 in adult ebrafish are the caudal neurosecretory system and brain. By using T-PCR analysis, we show that uts1 mRNA is also present in ovary, aternally contributed to the embryo, and expressed throughout embryonic evelopment. Expression of ucn3 mRNA was detected in a range of adult issues and during developmental stages from 24 hours post fertilization nward. Analysis of spatial transcript distributions by whole-mount in itu hybridization revealed limited forebrain expression of uts1 and cn3 during early development. Small numbers of uts1-synthesizing eurons were found in subpallium, hypothalamus, and posterior iencephalon, whereas ucn3-positive cells were restricted to elencephalon and retina. The brainstem was the main site of uts1 and cn3 synthesis in the embryonic brain. uts1 Expression was confined to he midbrain tegmentum; distinct hindbrain cell groups, including locus oeruleus and Mauthner neurons; and the spinal cord. ucn3 Expression was ocalized to the optic tectum, serotonergic raphe, and distinct hombomeric cell clusters. The prominent expression of uts1 and ucn3 in rainstem is consistent with proposed roles of CRH-related peptides in tress-induced modulation of locomotor activity through monoaminergic rainstem neuromodulatory systems.

- BACKGROUND: At the end of the 19th century, infant mortality was high in urban and rural areas in Sweden. In Stockholm, the mortality rate was particularly high among foster children. This study addresses the importance for health of targeted public policies and their local implementation in the reduction of excess mortality among foster children in Stockholm at the turn of the 19th century. In response to public concern, a law was passed in 1902 on inspections of foster homes. Stockholm city employed a handful of inspectors who visited foster homes and advised parents on child care and feeding. METHODS: Analysis of historical records from the City of Stockholm was combined with epidemiological analysis of mortality rates and hazard ratios on individual-level data for 112 746 children aged <1 year residing in one part of Stockholm between 1878 and 1925. Hazard ratios of mortality were calculated using Cox' regression analysis. RESULTS: Mortality rates of foster infants exceeded 300/1000 before 1903. Ten years later the mortality rates among foster children had declined and were similar to other children born in and out of wedlock. Historical accounts and epidemiological analysis of individual-level data over a longer time period showed similar results. CONCLUSIONS: Targeted policy measures to foster children may have potentiated the positive health effects of other universal policies, such as improved living conditions, clean water and sanitation for the whole population in the city, contributing to an equalization of mortality rates between different groups.

- OBJECTIVES: Little research has focused on the relation of immigration and suicidal behaviour in youth. Nevertheless, the impact of migration on the mental health of youth is an issue of increasing societal importance. This review aimed to present studies on the prevalence of suicidal behaviour in immigrant youth in various countries and to provide possible explanations for suicidal behaviour in immigrant youth, especially regarding acculturation.METHODS: The review included a literature search to locate articles on the subject of suicidal behaviour in immigrant youth in the context of acculturation.RESULTS: Studies on suicidal behaviour in culturally diverse youth are few and most of the existing research does not differentiate ethnic minorities from immigrants. Studies on epidemiology and on specific risk factors were found regarding various immigrant youth including Hispanics in the United States, Asians in North America and Europe, as well as comparative studies between different immigrant groups in specific countries.CONCLUSIONS: The relation between immigration status and suicidal behaviours in youth appears to vary by ethnicity and country of settlement. Time spent in the new country as well as intergenerational communication and conflicts with parents have, in many of the studies, been related to suicidality in immigrant youth. Summing up, there is a clear and urgent need to further pursue the work in this field, to develop targeted public health interventions as well as psychosocial treatment for preventing suicide in these youth.
