The Interplay of Variants Near LEKR and CCNL1 and Social Stress in Relation to Birth Size

Background We previously identified via a genome wide association study variants near LEKR and CCNL1 and in the ADCY5 genes lead to lower birthweight. Here, we study the impact of these variants and social stress during pregnancy, defined as social adversity and neighborhood disparity, on infant birth size. We aimed to determine whether the addition of genetic variance magnified the observed associations. Methodology/Principal Findings We analyzed data from the Northern Finland Birth Cohort 1986 (n = 5369). Social adversity was defined by young maternal age (<20 years), low maternal education (<11 years), and/or single marital status. Neighborhood social disparity was assessed by discrepancy between neighborhoods relative to personal socio-economic status. These variables are indicative of social and socioeconomic stress, but also of biological risk. The adjusted multiple regression analysis showed smaller birth size in both infants of mothers who experienced social adversity (birthweight by −40.4 g, 95%CI −61.4, −19.5; birth length −0.14 cm, 95%CI −0.23, −0.05; head circumference −0.09 cm 95%CI −0.15, −0.02) and neighborhood disparity (birthweight −28.8 g, 95%CI −47.7, −10.0; birth length −0.12 cm, 95%CI −0.20, −0.05). The birthweight-lowering risk allele (SNP rs900400 near LEKR and CCNL1) magnified this association in an additive manner. However, likely due to sample size restriction, this association was not significant for the SNP rs9883204 in ADCY5. Birth size difference due to social stress was greater in the presence of birthweight-lowering alleles. Conclusions/Significance Social adversity, neighborhood disparity, and genetic variants have independent associations with infant birth size in the mutually adjusted analyses. If the newborn carried a risk allele rs900400 near LEKR/CCNL1, the impact of stress on birth size was stronger. These observations give support to the hypothesis that individuals with genetic or other biological risk are more vulnerable to environmental influences. Our study indicates the need for further research to understand the mechanisms by which genes impact individual vulnerability to environmental insults

Autonomy, job satisfaction and professional self-image among nurses in the context of a physicians' strike

This paper tests the hypothesis that structural changes in nurses' work settings, which allow nurses to autonomously exercise their knowledge and skills will lead not only to an enhanced feeling of professional autonomy, but also to an improvement in their professional self-image and to an increase in job satisfaction. An opportunity to test this hypothesis arose when physicians in Israel went on a strike which lasted 116 days. Primary care (PC) clinics were completely abandoned by physicians, leaving nurses to operate them on their own, while in hospitals, nurses continued to work as usual under physicians' supervision. The study compares the effect of the strike on head nurses in the two sectors. Data were collected by means of self administered questionnaires. The findings indicate that during the strike, PC head nurses expanded their activities and responsibilities and consequently felt more professional autonomy and job satisfaction, as well as an improvement in professional self-image. Hospital head nurses experienced significantly less changes in their work situation and, as expected, less change in all work related attitudes. It is suggested that, when given the opportunity to define for themselves roles where they can use their experience, knowledge and skills, senior nurses stand up to the challenge and consequently are more satisfied and their professional self-image improves.nurses autonomy job satisfaction physicians' strike primary care hospitals Israel

Nurses autonomy and job satisfaction

Nurses' autonomy is structurally limited by physicians' close supervision and control. A prolonged physicians' strike in Israel in 1983 created a special situation where for 3 months nurses had to provide primary health care services without physicians. This study, undertaken at the end of the strike, focuses on nurses' comparative perceptions of autonomy and job satisfaction with relation to role performance during the strike and in usual work conditions. Data were collected by means of a self-administered questionnaire. Sixty one percent (n = 1144) of the primary health care nurses in Israel responded. The strike situation increased the normal work load of the nurses, but it also gave many nurses the opportunity to initiate and carry out special programs in their clinics and communities. The majority of nurses report that in general they are satisfied with their work and perceive it as autonomous. The increase in routine as well as self-initiated activities was found to be positively but weakly correlated with an increase in job satisfaction and in the perception of role autonomy during the strike. These findings suggest that even after, or perhaps because of, being exposed to a significant change in contextual autonomy (working without physicians for a prolonged period of time) most Israeli primary care nurses do not appear to desire increased autonomy in the work place.autonomy job satisfaction primary care nurses physicians strike

Status and risk factors of unintentional injuries among Chinese undergraduates: a cross-sectional study

<p>Abstract</p> <p>Background</p> <p>Injuries affect all age groups but have a particular impact on young people. To evaluate the incidence of non-fatal, unintentional, injuries among undergraduates in Wenzhou, China, assess the burden caused by these injuries, and explore the associated risk factors for unintentional injuries among these undergraduates, we conducted a college-based cross-sectional study.</p> <p>Methods</p> <p>Participants were selected by a multi-stage random sampling method, and 2,287 students were asked whether they had had an injury in the last 12 months; the location, cause, and consequences of the event. The questionnaire included demographic and socioeconomic characteristics, lifestyle habits, and the scale of type A behaviour pattern (TABP). Multivariate logistic regression models were used; crude odds ratios (ORs), adjusted ORs and their 95% confidence intervals (CIs) were estimated, with students having no injuries as the reference group.</p> <p>Results</p> <p>The incidence of injuries among undergraduates in Wenzhou was 18.71 injuries per 100 person-years (95%CI: 17.12~20.31 injuries per 100 person-years). Falls were the leading cause of injury, followed by traffic injuries, and animal/insect bites. Male students were more likely to be injured than female students. Risk factors associated with unintentional injuries among undergraduates were: students majoring in non-medicine (adjusted OR: 1.53; 95% CI: 1.19-1.96); type A behaviour pattern (adjusted OR: 2.99; 95% CI: 1.45-6.14); liking sports (adjusted OR: 1.86; 95% CI: 1.41-2.45).</p> <p>Conclusions</p> <p>Injuries have become a public health problem among undergraduates. Falls were the major cause of non-fatal injury. Therefore, individuals, families, schools and governments should promptly adopt preventive measures aimed at preventing and controlling morbidity due to non-fatal injury, especially among students identified to be at high-risk; such as male students with type A behaviour pattern who like sports.</p

Job satisfaction trends during nurses' early career

BackgroundJob satisfaction is an important component of nurses' lives that can impact on patient safety, productivity and performance, quality of care, retention and turnover, commitment to the organisation and the profession. Little is known about job satisfaction in early career and how it varies for different groups of nurses. This paper investigates how the components of job satisfaction vary during early career in newly qualified UK nurses.MethodsNurses were sampled using a combined census and multi-stage approach (n = 3962). Data were collected by questionnaire at 6 months, 18 months and 3 years after qualification between 1998 and 2001. Scores were calculated for seven job satisfaction components and a single item that measured satisfaction with pay. Scores were compared longitudinally and between nursing speciality (general, children's, mental health) using a mixed model approach.ResultsNo single pattern across time emerged. Trends varied by branch and job satisfaction component. Rank order of job satisfaction components, from high to low scores, was very similar for adult and child branch nurses and different for mental health. Nurses were least satisfied with pay and most satisfied with relationships at 6 and 18 months and with resources (adult and child) and relationships (mental health) at 3 years. Trends were typically upwards for adult branch nurses, varied for children's nurses and downwards for mental health nurses.ConclusionThe impact of time on job satisfaction in early career is highly dependent on specialism. Different contexts, settings and organisational settings lead to varying experiences. Future research should focus on understanding the relationships between job characteristics and the components of job satisfaction rather than job satisfaction as a unitary construct. Research that further investigates the benefits of a formal one year preceptorship or probationary period is needed.<br/
