Increases in glucocorticoids are sufficient but not necessary to increase cooperative burrowing in Damaraland mole-rats

Despite widespread interest in the evolution of cooperative behaviour, the physiological mechanisms shaping their expression remain elusive. We tested the hypothesis that glucocorticoid (GC) hormones affect cooperative behaviour using captive Damaraland mole-rats (Fukomys damarensis), a cooperatively breeding mammal. Within groups, individuals routinely contribute to public goods that include foraging tunnels, which provide all group members access to the tubers of desert plants they feed on, communal food stores and nests. We found that experimental increases in glucocorticoid concentration (GCc) in non-breeding female helpers led them to be active for longer and to burrow more while active, raising their daily contributions to burrowing, but not food carrying or nest building. However, experimentally induced increases in burrowing did not lead to elevated GCc in helpers of both sexes. These results suggest that heightened GCc may stimulate some cooperative behaviours that are energetically demanding (a characteristic shared by many types of cooperative activities across species) but that the cooperative behaviours affected by GCc can also be regulated by other mechanisms.

A meta-analysis of hormone administration effects on cooperative behaviours: Oxytocin, vasopressin, and testosterone

The hormones oxytocin, vasopressin, and testosterone have been implicated in cooperative behaviours and have attracted increasing research interest for their potential to regulate human cooperation in both healthy and clinical populations. However, the behavioural effects of the administration of these hormones remain to be verified. The current analysis included 41 studies involving 3,269 participants with a narrow age range. We examined the administration effects of these hormones on cooperative behaviour and the regulatory effects of individual characteristics, hormone interventions, and task structure and context. Results revealed a moderate positive effect size of oxytocin intranasal administration, a large negative effect size of vasopressin intranasal administration, and nonsignificant effects of testosterone administration on cooperative behaviours. Participants with mental dysfunctions were less sensitive to oxytocin and vasopressin administration. Oxytocin administration was effective in an in-group situation and for initial choices, corroborating a Tit-for-Tat strategy.

The relationship between individual phenotype and the division of labour in naked mole-rats: it's complicated

Background

The naked mole-rat (Heterocephalus glaber) is among the most social mammals on the planet, living in eusocial groups of up to 300 individuals that contain a single reproductive female and up to three reproductive males. A critical aspect of their complex social system is the division of labour that allows non-breeders to form an effective workforce. Age- or weight-based polyethisms are widely cited as explanations for how labour is divided, but evidence in support of these hypotheses has been equivocal.

Methods

To assess the extent to which individual working behaviour is determined by sex, age, weight and social rank, we studied the behaviours of 103 animals from eight captive colonies. We performed focal sampling and ran mixed-effects models to assess which factors explained variation in working behaviour during six ten-minute observation periods per individual.

Results

Contrary to widely-held beliefs, we found that working behaviour did not decrease linearly with weight, although polynomial regressions indicated younger and medium-sized individuals worked most frequently, while high-ranking individuals worked for the shortest periods of time. Working behaviour and its relationship with individual characteristics also varied between colonies.

Conclusions

While age- or size-based polyethisms may have some influence on working behaviour, we argue that other characteristics of the individual and colony are also important. In particular, the interactions of individual, social and environmental factors must be considered in order to understand the emergence and effectiveness of the division of labour that is so critical to many social organisms.

Procedural fairness predicts cooperative behaviour for high-self-esteem individuals but not for low-self-esteem individuals

Cooperation is vital for modern society. Previous studies showed that procedural fairness promotes cooperation; however, they mainly focused on cooperation intention, which may fail to reveal actual cooperative behaviour. Moreover, little is known regarding the personality boundary of the effect of procedural fairness on cooperation. Guided by previous findings that self-esteem increases sensitivity to procedural unfairness, we attempted to explore the moderating effect of self-esteem on the association between procedural fairness and cooperative behaviour. In Experiment 1, 160 participants' self-esteem was measured using the Rosenberg Self-Esteem Scale; procedural fairness was manipulated in two conditions, depending on whether money was allocated in an economic game by rolling the dice twice or an allocator's arbitrary choice. Cooperative behaviour was assessed using the chicken game paradigm. Experiment 2 (148 participants) aimed to replicate and extend the results of Experiment 1 using a more rigorous experimental design, in which the possible effect of outcome favourability was excluded. The results of both experiments consistently showed that procedural fairness positively predicted cooperative behaviour, and this association was significant in high-self-esteem individuals, but not in low-self-esteem individuals. These findings shed light on the vital role of self-esteem in understanding the relationship between procedural fairness and cooperative behaviour.

Estradiol shapes mutualistic behaviour of female cleaner fish (Labroides dimidiatus - Valenciennes, 1839): Potential implications of environmental disturbance

The presence of endocrine-derived compounds in the environment occurs due to a myriad of human or industrial activity and can disrupt the endocrine system of animals, including fish. One important group of endocrine disruptors are the estrogens, such as 17-β estradiol (E₂, estradiol). Estrogens are gonadal steroid hormones, able to be influential even in small concentrations. Here, we demonstrate that E₂ is linked to female' decisions made by an important coral reef species, the cleaner fish Labroides dimidiatus, during interactions with other reef fishes (known as clients). E₂ treatment in natural conditions interfered directly in the cooperative relationships, by increasing cleaners' willingness to interact with clients, providing greater amounts of physical contact to their fish partners. We discuss the meaning of the observed behavioural disruption produced by E₂, which by affecting a key species (cleaners) may produce a cascade impact in the aquatic ecosystem.

Ward social workers' views of what facilitates or hinders collaboration with specialist palliative care team social workers: A grounded theory

BACKGROUND

Inpatient, generalist social workers in discharge planning roles work alongside specialist palliative care social workers to care for patients, often resulting in two social workers being concurrently involved in the same patient's care. Previous studies identifying components of effective collaboration, which impacts patient outcomes, care efficiency, professional job satisfaction, and healthcare costs, were conducted with nurses and physicians but not social workers. This study explores ward social workers' perceptions of what facilitates or hinders collaboration with palliative care social workers.

METHODS

Grounded theory was used to explore the research aim. In-depth qualitative interviews with masters trained ward social workers (n = 14) working in six hospitals located in the Midwest, United States were conducted between February 2014 and January 2015. A theoretical model of ward social workers' collaboration with palliative care social workers was developed.

RESULTS

The emerging model of collaboration consists of: 1) trust, which is comprised of a) ability, b) benevolence, and c) integrity, 2) information sharing, and 3) role negotiation. Effective collaboration occurs when all elements of the model are present.

CONCLUSION

Collaboration is facilitated when ward social workers' perceptions of trust are high, pertinent information is communicated in a time-sensitive manner, and a flexible approach to roles is taken. The theoretical model of collaboration can inform organisational policy and social work clinical practice guidelines, and may be of use to other healthcare professionals, as improvements in collaboration among healthcare providers may have a positive impact on patient outcomes.

GPs' and dentists' experiences and expectations of interprofessional collaboration: findings from a qualitative study in Germany

BACKGROUND

Against the background of well-described associations between oral and general health, collaboration between dentists and general practitioners (GP) is crucial to provide therapeutic and preventive patient care. However, in the German health system, GPs and dentists are organizationally separated, implying that interprofessional collaboration can only occur informally and on a voluntary basis. Given the scarce evidence of interprofessional collaboration between dentists and GPs, an explorative study was conducted. This paper outlines the findings of this study with regard to GPs' and dentists' experiences and expectations of interprofessional collaboration.

METHODS

Semi-structured interviews were conducted with GPs (n = 15) and dentists (n = 13) from three structurally different regions in Baden-Wurttemberg, Germany. The interview guide included questions on occasions, expectations and experiences of interprofessional collaboration. The interviews were transcribed verbatim and analysed using qualitative content analysis according to Mayring.

RESULTS

Both GPs and dentists reported perceived knowledge deficits of the other profession with regard to medication, particularly anticoagulants and bisphosphonates, as well as systemic and general respectively dental diseases. Expectations regarding the scope of collaboration diverge: whereas dentists were interested in extending collaboration, most GPs saw no need for collaboration.

CONCLUSIONS

The perceived medical knowledge deficits of the other profession as well as divergent expectations concerning the scope of collaboration hinder profound and regular interprofessional collaboration between GPs and dentists. These perceived knowledge deficits may be rooted in the separate education of dentists and GPs in Germany. Fostering interprofessional education is a promising way to improve cooperation between GPs and dentists in the long term.

Interprofessional primary care team meetings: a qualitative approach comparing observations with personal opinions

BACKGROUND

The number of people with multiple chronic conditions requiring primary care services increases. Professionals from different disciplines collaborate and coordinate care to deal with the complex health care needs. There is lack of information on current practices regarding interprofessional team (IPT) meetings.

OBJECTIVES

This study aimed to improve our understanding of the process of interprofessional collaboration in primary care team meetings in the Netherlands by observing the current practice and exploring personal opinions.

METHODS

Qualitative study involving observations of team meetings and interviews with participants. Eight different IPT meetings (n = 8) in different primary care practices were observed by means of video recordings. Experiences were explored by conducting individual semi-structured interviews (n = 60) with participants (i.e. health care professionals from different disciplines) of the observed team meetings. The data were analysed by means of content analysis.

RESULTS

Most participants expressed favourable opinions about their team meetings. However, observations showed that team meetings were more or less hectic, and lacked a clear structure and team coordinator or leader. There appears to be a discrepancy between findings from observations and interviews. From the interviews, four main themes were extracted: (1) Team structure and composition, (2) Patient-centredness, (3) Interaction and (4) Attitude and motivation.

CONCLUSION

IPT meetings could benefit from improvements in structure, patient-centredness and leadership by the chairpersons. Given the discrepancy between observations and interviews, it would appear useful to improve team members' awareness of aspects that could be improved before training them in dealing with specific challenges.

Interprofessional collaboration regarding patients' care plans in primary care: a focus group study into influential factors

BACKGROUND

The number of people with multiple chronic conditions demanding primary care services is increasing. To deal with the complex health care demands of these people, professionals from different disciplines collaborate. This study aims to explore influential factors regarding interprofessional collaboration related to care plan development in primary care.

METHODS

A qualitative study, including four semi-structured focus group interviews (n = 4). In total, a heterogeneous group of experts (n = 16) and health care professionals (n = 15) participated. Participants discussed viewpoints, barriers, and facilitators regarding interprofessional collaboration related to care plan development. The data were analysed by means of inductive content analysis.

RESULTS

The findings show a variety of factors influencing the interprofessional collaboration in developing a care plan. Factors can be divided into 5 key categories: (1) patient-related factors: active role, self-management, goals and wishes, membership of the team; (2) professional-related factors: individual competences, domain thinking, motivation; (3) interpersonal factors: language differences, knowing each other, trust and respect, and motivation; (4) organisational factors: structure, composition, time, shared vision, leadership and administrative support; and (5) external factors: education, culture, hierarchy, domain thinking, law and regulations, finance, technology and ICT.

CONCLUSIONS

Improving interprofessional collaboration regarding care plan development calls for an integral approach including patient- and professional related factors, interpersonal, organisational, and external factors. Further, the leader of the team seems to play a key role in watching the patient perspective, organising and coordinating interprofessional collaborations, and guiding the team through developments. The results of this study can be used as input for developing tools and interventions targeted at executing and improving interprofessional collaboration related to care plan development.

Establishing an Anaesthesia and Intensive Care partnership and aiming for national impact in Tanzania

Anaesthesia and Intensive Care is a neglected specialty in low-income countries. There is an acute shortage of health workers – several low-income countries have less than 1 anaesthesia provider per 100,000 population. Only 1.5 % of hospitals in Africa have the intensive care resources needed for managing patients with sepsis. Health partnerships between institutions in high and low-income countries have been proposed as an effective way to strengthen health systems. The aim of this article is to describe the origin and conduct of a health partnership in Anaesthesia and Intensive Care between institutions in Tanzania and Sweden and how the partnership has expanded to have an impact at regional and national levels.

The Muhimbili-Karolinska Anaesthesia and Intensive Care Collaboration was initiated in 2008 on the request of the Executive Director of Muhimbili National Hospital in Dar es Salaam. The partnership has conducted training courses, exchanges, research projects and introduced new equipment, routines and guidelines. The partnership has expanded to include all hospitals in Dar es Salaam. Through the newly formed Life Support Foundation, the partnership has had a national impact assisting the reanimation of the Society of Anaesthesiologists of Tanzania and has seen a marked increase of the number of young doctors choosing a residency in Anaesthesia and Intensive Care.

What is the impact of multidisciplinary team simulation training on team performance and efficiency of patient care? An integrative review

BACKGROUND

In hospital emergencies require a structured team approach to facilitate simultaneous input into immediate resuscitation, stabilisation and prioritisation of care. Efforts to improve teamwork in the health care context include multidisciplinary simulation-based resuscitation team training, yet there is limited evidence demonstrating the value of these programmes.(1) We aimed to determine the current state of knowledge about the key components and impacts of multidisciplinary simulation-based resuscitation team training by conducting an integrative review of the literature.

METHODS

A systematic search using electronic (three databases) and hand searching methods for primary research published between 1980 and 2014 was undertaken; followed by a rigorous screening and quality appraisal process. The included articles were assessed for similarities and differences; the content was grouped and synthesised to form three main categories of findings.

RESULTS

Eleven primary research articles representing a variety of simulation-based resuscitation team training were included. Five studies involved trauma teams; two described resuscitation teams in the context of intensive care and operating theatres and one focused on the anaesthetic team. Simulation is an effective method to train resuscitation teams in the management of crisis scenarios and has the potential to improve team performance in the areas of communication, teamwork and leadership.

CONCLUSION

Team training improves the performance of the resuscitation team in simulated emergency scenarios. However, the transferability of educational outcomes to the clinical setting needs to be more clearly demonstrated.

General practitioners' and occupational health physicians' views on their cooperation: a cross-sectional postal survey

PURPOSE

Prevention, rehabilitation and reintegration into the workplace are examples of overlapping work fields of general practitioners (GPs) and occupational health physicians (OPs). In Germany, however, cooperation between GPs and OPs is often lacking or suboptimal. In this article, we present GPs' and OPs' views on a variety of aspects of their cooperation and differences between them.

METHODS

Survey questionnaire was developed on the basis of literature research and results of focus group interviews. Cross-sectional postal survey among GPs (n = 1000) and OPs (n = 383) was performed in the federal state of Baden-Württemberg, Germany. Explorative descriptive and logistic regression analyses were carried out (controlling for potential confounders).

RESULTS

Response rates were 31 and 48 %, respectively. Mutual telephone calls were the most frequent contact medium (49 and 91 %, respectively). Both groups considered themselves to have clearly separate areas of responsibility (median = 4, rating scale from 1 "agree not at all" to 5 "agree definitely"). Necessity to cooperate and need to improve cooperation were both rated as 4 (by GPs) and 5 (by OPs), respectively (p < 0.001, Wilcoxon test). Several variables were found to be different by logistic regression analysis of answers from the two groups (e.g. in regard to importance of rehabilitation, primary prevention services, caring for chronically ill workers or changing of workplace conditions). Sensitive topics (e.g. concerning mutual rivalry, remuneration or adherence to medical confidentiality) were also found to be rated differently.

CONCLUSION

The data show potential interest of both physicians groups to develop cooperation. As the ratings often differed significantly, particularly in regard to statements presented, answers influenced by social desirability are generally unlikely.

[The use of Facebook in Spanish associations of rare diseases: how and what is it used for?]

OBJECTIVE

To study whether the use of Facebook is widespread in the field of patient associations for rare diseases and, if so, the purpose for which the site is being used.

METHOD

A descriptive study was conducted to determine whether associations within the Spanish Federation for Rare Diseases use Facebook and, if so, the type of use and its objectives. The analysis was performed based on a categorization system that has been used in the field of chronic diseases and has been adapted to the specific characteristics of rare diseases.

RESULTS

Associations use Facebook to raise awareness of rare diseases in general and particularly to share content related to psychological, medical and social support, the promotion and dissemination of research, and fundraising.

CONCLUSIONS

The alignment between the interests of associations through their presence on Facebook and policy areas of the national strategy for rare diseases is a reason for optimism about the feasibility of using Facebook as a tool for encounters and collaborative work.

Patient participation in nursing care on medical wards: An integrative review

BACKGROUND

Patient participation is a way for patients to engage in their nursing care. In view of the possible link between patient participation and safety, there is a need for an updated review to assess patient participation in nursing care.

OBJECTIVES

To investigate patients' and nurses' perceptions of and behaviours towards patient participation in nursing care in the context of hospital medical wards.

DESIGN

Integrative review.

DATA SOURCES

Three search strategies were employed in August 2013; a computerised database search of Cumulative Index of Nursing and Allied Health Literature, Cochrane Library, Medline and PsychINFO; reference lists were hand-searched; and forward citation searching was executed.

REVIEW METHODS

After reviewing the studies, extracting study data and completing summary tables the methodological quality was assessed using the Mixed-Methods Assessment Tool by two reviewers. Reviewers met then to discuss discrepancies as well as the overall strengths and limitations of the studies. Discrepancies were overcome through consensus or a third reviewer adjudicated the issue. Within and across study analysis and synthesis of the findings sections was undertaken using thematic synthesis.

RESULTS

Eight studies met inclusion criteria. Four themes were identified - enacting participation, challenges to participation, promoting participation and types of participation. Most studies included were conducted in Europe. The majority of studies used qualitative methodologies, with all studies sampling patients; nurses were included in three studies. Data were largely collected using self-reported perceptions; two studies included observational data. Methodological issues included a lack of reflexivity, un-validated data collection tools, sampling issues and low response rates.

CONCLUSIONS

On medical wards, patients and nurses desire, perceive or enact patient participation passively. Challenging factors for patient participation include patients' willingness, nurses' approach and confusion around expectations and roles. Information-sharing was identified as an activity that promotes patient participation, suggesting nurses encourage active communication with patients in practice. Involving patients in assessment and care planning may also enhance patient participation. For education, enhancing nurses' understanding of the attributes of patient participation, as well as patient-centred care approaches may be beneficial for medical ward nurses. From here, researchers need to examine ways to overcome the barriers to patient participation; further nurse participants and observational data is required on medical wards.

Male and female breeding strategies in a cooperative primate

Marmosets are cooperative breeders organized as extended family groups, but breeding is generally restricted to a single pair. Breeding competition is fierce in female marmosets; males, on the other hand, show low levels of intragroup aggression. We investigated male and female breeding strategies and the resulting reproductive output in 9 wild groups. Reproductive output, tenure of breeding animals, identification of the breeding system, breeding position replacements, migration and infanticide were recorded; also, we recorded grooming and aggression. Replacement of the breeding male or female was observed on nine occasions. On four occasions, the son of the breeding male inherited the breeding post, but we never observed inheritance of a breeding post by a daughter. Mostly, females attained a breeding post by immigrating to a group that had a breeding vacancy. Our results showed that Callithrix jacchus males and females use different strategies to attain a breeding position and maintain it for as long as possible. These strategies prolong the tenure of the breeding position, which is the best way to produce a large number of offspring. This article is part of a Special Issue entitled: Neotropical Behaviour.

Synchronised provisioning at the nest: parental coordination over care in a socially monogamous species

Bi-parental care is very common in birds, occurring in over 90% of species, and is expected to evolve whenever the benefits of enhanced offspring survival exceed the costs to both parents of providing care. In altricial species, where the nestlings are entirely dependent on the parents for providing food until fledging, reproductive success is related to the capacity of the parents to provision the offspring at the nest. The degree to which parents synchronise their visits to the nest is rarely considered by studies of bi-parental care, and yet may be an important component of parental care, affecting the outcome of the reproductive attempt, and the dynamics of sexual conflict between the parents. Here we studied this aspect of parental care in the long-tailed finch (Poephila acuticauda), a socially monogamous estrildid finch. We monitored parental nest visit rates and the degree of parental visit synchrony, and assessed their effects on reproductive success (e.g., brood size, number of offspring fledged and nestling growth).

The frequency of nest visits in a day was low in this species (<1 visit/h), but there was a high level of synchrony by the two partners with 73% of visits made together. There was a correlation between the proportion of visits that were made by the pair together and the size of the brood at hatching, although it was not related to the number of fledglings a pair produced, or the quality of those offspring. We suggest that nest visit synchrony may primarily be driven by the benefit of parents being together whilst foraging away from the nest, or may reduce nest predation by reducing the level of activity around the nest throughout the day.
