Evaluation of nurses' perceptions of the impact of targeted depression education and a screening and referral tool in an acute cardiac setting.

AIMS AND OBJECTIVES: The aim of this study was to evaluate nurses' perceptions of an education programme and screening and referral tool designed for cardiac nurses to facilitate depression screening and referral procedures for patients with coronary heart disease. BACKGROUND: There is a high prevalence of depression in patients with coronary heart disease that is often undetected. It is important therefore that nurses working with cardiac patients are equipped with the knowledge and skills to recognise the signs and symptoms of depression and refer appropriately. DESIGN: A qualitative approach with purposive sampling and semi-structural interviews was implemented within the Donabedian 'Structure-Process-Outcome' evaluation framework. METHODS: Semi-structured interviews were conducted with 14 cardiac nurses working in a major metropolitan hospital six weeks post-attending an education programme on depression and coronary heart disease. Thematic data analysis was implemented, specifically adhering to Halcomb and Davidson's (2006) pragmatic data analysis, to examine nurse knowledge and experience of depression assessment and referral in an acute cardiac ward. RESULTS: The key findings of this study were that the education programme: (1) increased the knowledge base of nurses working with cardiac patients on comorbid depression and coronary heart disease, and (2) assisted in the identification of depression and the referral of 'at risk' patients. CONCLUSIONS: Emphasis was placed on the translational significance of educating cardiac nurses about depression via the introduction of a depression screening and referral instrument designed specifically for use in the cardiac ward. As a result, participants found they were better equipped to identify depressive symptoms and, guided by the screening instrument, to confidently instigate referral procedures. RELEVANCE TO CLINICAL PRACTICE: Much complexity lies in caring for cardiac patients with depression, including issues such as misdiagnosis. Targeted education, including use of appropriate instruments, has the potential to facilitate early recognition of the signs and symptoms of depression in the acute cardiac setting.

Contact & connect-an intervention to reduce depression stigma and symptoms in construction workers: protocol for a randomised controlled trial

BACKGROUND: Males employed in the construction industry have high rates of suicide. Although reasons underpinning this risk are multifaceted, poor help-seeking and stigma are represent major contributors. Males in the construction industry are also exposed to other risk factors for mental ill health and suicide, including unemployment. Sigma-reducing interventions that are accessible and attractive to recently unemployed males in the construction industry could therefore improve help-seeking, and address depression and suicidal behaviour in this population. METHODS/DESIGN: Contact&Connect will use a parallel individual randomized design to evaluate the effectiveness of a multimedia-based intervention aimed at reducing stigma. The intervention consists of a package of 12 brief contact interventions (BCIs) delivered over a six month period. BCIs will direct participants to informational programs and microsites. Content will address three major themes: debunking depression myths and stereotypes, normalisation, and empowerment. Target enrolment is 630 (315 in each arm), each to be followed for 12 months. Eligible participants will be males, between 30 and 64 years, unemployed at the time of recruitment, registered with Incolink (a social welfare trustee company for unemployed members of the construction industry), and own a smart phone with enabled internet connectivity. DISCUSSION: At present, there are no programs that have been shown to be effective in reducing stigma in the blue-collar male population. Contact&Connect promises to provide a tailored, efficient, and scalable approach to reducing stigma, depressive symptoms and suicidality among unemployed males.

Signs and codes in early childhood: An investigation of young children’s creative approaches to communication

PEOPLE COMMUNICATE AND MAKE meaning through the use of the signs, codes and rules of their community and its language/s. On the way to learning these signs, codes and rules, children often create or invent their own unique and sometimes temporary systems of meaning making. In this paper we use Vygotsky’s concept of semiotic mediation and Bernstein’s code theory to reflect on some examples of children’s creative approaches to communication that involved the creation and use of signs. We will argue that young language learners’ invention of their own languages and creative use of drawing as a form of sign creation are symbolic expressions of their intent to generate and reinforce desired social and cultural situations of learning. We conclude that individuals mediate social and individual functioning in order to make meaning of their world, and argue for a move away from viewing second language learning and emergent writing as static sets of abilities to a more dynamic interpretation.

Relationship between executive functioning and symptoms of attention-deficit/hyperactivity disorder and autism spectrum disorder in 6-8 year old children

This study examined relationships between executive functioning (EF) and ADHD/ASD symptoms in 339 6-8 year-old children to characterise EF profiles associated with ADHD and ADHD + ASD. ADHD status was assessed using screening surveys and diagnostic interviews. ASD symptoms were measured using the Social Communication Questionnaire, and children completed assessments of EF. We found the EF profile of children with ADHD + ASD did not differ from ADHD-alone and that lower-order cognitive skills contributed significantly to EF. Dimensionally, ASD and inattention symptoms were differentially associated with EF, whereas hyperactivity symptoms were unrelated to EF. Differences between categorical and dimensional findings suggest it is important to use both diagnostic and symptom based approaches in clinical settings when assessing these children's functional abilities.

Muscle damage and inflammation during recovery from exercise

Unaccustomed exercise consisting of eccentric (i.e., lengthening) muscle contractions often results in muscle damage characterized by ultrastructural alterations in muscle tissue, clinical signs and symptoms (e.g., reduced muscle strength and range of motion, increased muscle soreness and swelling, efflux of myocellular proteins). The time course of recovery following exercise-induced muscle damage depends on the extent of initial muscle damage, which in turn is influenced by the intensity and duration of exercise, joint angle/muscle length and muscle groups used during exercise. The effects of these factors on muscle strength, soreness and swelling are well characterized. By contrast, much less is known about how they affect intramuscular inflammation and molecular aspects of muscle adaptation/remodeling. Although inflammation has historically been viewed as detrimental for recovery from exercise, it is now generally accepted that inflammatory responses-if tightly regulated-are integral to muscle repair and regeneration. Animal studies have revealed that other cell types including mast cells, eosinophils, CD8 and T regulatory lymphocytes, fibro-adipogenic progenitors and pericytes also help to facilitate muscle tissue regeneration. However, more research is required to determine whether these cells respond to exercise-induced muscle damage. A large body of research has investigated the efficacy of physicotherapeutic, pharmacological and nutritional interventions for reducing the signs and symptoms of exercise-induced muscle damage, with mixed results. More research is needed to examine if/how these treatments influence inflammation and muscle remodeling during recovery from exercise.

Isolation of a novel Orientia species (O. chuto sp. nov.) from a patient infected in Dubai

In July 2006, an Australian tourist returning from Dubai, in the United Arab Emirates (UAE), developed acute scrub typhus. Her signs and symptoms included fever, myalgia, headache, rash, and eschar. Orientia tsutsugamushi serology demonstrated a 4-fold rise in antibody titers in paired serum collections (1:512 to 1:8,192), with the sera reacting strongest against the Gilliam strain antigen. An Orientia species was isolated by the in vitro culture of the patient's acute blood taken prior to antibiotic treatment. The gene sequencing of the 16S rRNA gene (rrs), partial 56-kDa gene, and the full open reading frame 47-kDa gene was performed, and comparisons of this new Orientia sp. isolate to previously characterized strains demonstrated significant sequence diversity. The closest homology to the rrs sequence of the new Orientia sp. isolate was with three strains of O. tsutsugamushi (Ikeda, Kato, and Karp), with a nucleotide sequence similarity of 98.5%. The closest homology to the 47-kDa gene sequence was with O. tsutsugamushi strain Gilliam, with a nucleotide similarity of 82.3%, while the closest homology to the 56-kDa gene sequence was with O. tsutsugamushi strain TA686, with a nucleotide similarity of 53.1%. The molecular divergence and geographically unique origin lead us to believe that this organism should be considered a novel species. Therefore, we have proposed the name “Orientia chuto,” and the prototype strain of this species is strain Dubai, named after the location in which the patient was infected.

Neurological complication of systemic cancer

Neurological complications of systemic cancer—those arising outside the nervous system—can be distressing, disabling, and sometimes fatal. Diagnosis is often difficult because different neurological disorders may present with similar signs and symptoms. Furthermore, comorbid neurological illnesses, common in elderly patients with cancer, can complicate diagnosis. Early diagnosis and aggressive treatment can improve neurological symptoms and can substantially enhance a patient's quality of life. We approach the problem of neurological complications of systemic cancer as would a neurologist: first by identifying the anatomical area or areas that are affected (ie, brain, spinal cord, peripheral nerve), then by evaluating the diagnostic approach, considering the symptoms and signs and including appropriate laboratory tests, and finally, by recommending treatment. We focus on disorders that are difficult to diagnose, need neurological consultation, and for which effective treatments exist.

The epidemiology of the first wave of H1N1 influenza pandemic in Australia : a population-based study

Objectives: Following the recent H1N1 influenza pandemic we were able to describe seropositivity in a repre-sentative sample of adults prior to the availability of a specific vaccine.

Methods: This cross-sectional serological study is set in the Barwon Statistical Division, Australia. Blood samples were collected from September 2009 through to May 2010, from 1184 individuals (569 men, 615 women; median age 61.7 years), randomly selected from electoral rolls. Serum was analysed for specific H1N1 immunity using a haemagglutina-tion inhibition test. A self-report provided information about symptoms, demographics and healthcare. Associations be-tween H1N1 infection, gender, households and occupation were determined using logistic regression, adjusting for age.

Results: Of 1184 individuals, 129 (58 men, 71 women) were seropositive. Gender-adjusted age-specific prevalence was: 8.3% 20-29 years, 13.5% 30-39, 10.4% 40-49, 6.5% 50-59, 9.7% 60-69, 10.3% 70-79, 18.8% 80+. Standardised preva-lence was 10.3% (95%CI 9.6-11.0). No associations were detected between seropositivity and gender (OR=0.82, 95%CI 0.57-1.19) or being a healthcare worker (OR=1.43, 95%CI 0.62-3.29). Smokers (OR=1.86, 95%CI 1.09-3.15) and those socioeconomically disadvantaged (OR=2.52, 95%CI 1.24-5.13) were at increased risk. Among 129 seropositive individu-als, 31 reported symptoms that were either mild (n = 13) or moderate (time off work, doctor visit, n = 18). For age <60, 39.6% of seropositive individuals reported symptoms, whereas the proportion was 13.2% for age 60+.

Conclusions: Following the pandemic, the proportion of seropositive adults was low, but significant subclinical infection was found. Social disadvantage increased the likelihood of infection. The low symptom rate for older ages may relate to pre-existing immunity.

Corticosteroid-induced psychiatric disturbances: it is time for pharmacists to take notice.

Corticosteroids are widely used to relieve signs and symptoms arising from many diseases, including common inflammatory and autoimmune disorders affecting a number of organ systems. However, corticosteroids also induce significant adverse effects; in particular, a range of severe psychiatric adverse effects may occur including delirium, depression, mania, psychosis and cognitive/memory impairment. These adverse effects occur in up to 60% of patients taking corticosteroids and recent studies show an increased rate of psychopathologies in this population. Long-term adverse effects on mood and behavior are severely debilitating, thereby influencing the quality of life, employment and health status of individuals taking corticosteroids. Strategies used to manage corticosteroid-induced psychiatric disturbances through psychotropic drugs vary significantly. This commentary summarizes existing literature on mechanisms underlying corticosteroid-induced psychiatric adverse effects and evidence associated with using psychotropic drugs to manage these effects. Despite its importance, there is an absolute dearth in the literature examining pharmacists' understanding and perceptions of psychiatric adverse effects of corticosteroids. Educational programs need to be implemented so that pharmacists can counsel patients about how to recognize corticosteroid-induced psychiatric disturbances. Physicians do not consistently alert patients to watch for behavioral changes, and patients may feel that mood changes they experience fall within the category of 'normal behavior,' and thus are less likely to report them. Given that patients taking corticosteroids usually have complex medical histories, discussions of adverse effects with pharmacists are vital to improve health outcomes in this population.

A question mark on zinc deficiency in 185 million people in Pakistan- possible way out

This paper reviews research published in recent years concerning the effects of zinc deficiency, its consequences, and possible solutions. Zinc is an essential trace element necessary for over 300 zinc metalloenzymes and required for normal nucleic acid, protein, and membrane metabolism. Zinc deficiency is one of the ten biggest factors contributing to burden of disease in developing countries. Populations in South Asia, South East Asia, and sub-Saharan Africa are at greatest risk of zinc deficiency. Zinc intakes are inadequate for about a third of the population and stunting affects 40% of preschool children. In Pakistan, zinc deficiency is an emerging health problem as about 20.6% children are found in the levels of zinc, below 60 μg/dL. Signs and symptoms caused by zinc deficiency are poor appetite, weight loss, and poor growth in childhood, delayed healing of wounds, taste abnormalities, and mental lethargy. As body stores of zinc decline, these symptoms worsen and are accompanied by diarrhea, recurrent infection, and dermatitis. Daily zinc requirements for an adult are 12-16 mg/day. Iron, calcium and phytates inhibit the absorption of zinc therefore simultaneous administration should not be prescribed. Zinc deficiency and its effects are well known but the ways it can help in treatment of different diseases is yet to be discovered. Improving zinc intakes through dietary improvements is a complex task that requires considerable time and effort. The use of zinc supplements, dietary modification, and fortifying foods with zinc are the best techniques to combat its deficiency.

International perspectives on psychosocial working conditions, mental health, and stress of dairy farm operators

Dairy farm operators-farmers, workers, and family members-are faced with many demands and stressors in their daily work and these appear to be shared across countries and cultures. Dairy operators experience high psychosocial demands with respect to a hard work and production ethos, economic influences, and social and environmental responsibility. Furthermore, both traditional and industrial farms are highly dependent on external conditions, such as weather, fluctuating markets, and regulations from government authorities. Possible external stressors include disease outbreaks, taxes related to dairy production, and recent negative societal attitudes to farming in general. Dairy farm operators may have very few or no opportunities to influence and control these external conditions, demands, and expectations. High work demands and expectations coupled with low control and lack of social support can lead to a poor psychosocial work environment, with increased stress levels, ill mental health, depression, and, in the worst cases, suicide. Internationally, farmers with ill mental health have different health service options depending on their location. Regardless of location, it is initially the responsibility of the individual farmer and farm family to handle mental health and stress, which can be of short- or long-term duration. This paper reviews the literature on the topics of psychosocial working conditions, mental health, stress, depression, and suicide among dairy farm operators, farm workers, and farm family members in an international perspective.

Complementary therapies and diabetes

There is increasing recognition that people with diabetes use a range of complementary therapies (CT), for a number of conditions, but do not always inform their conventional health practitioners about their use. Controlling blood glucose levels in people with diabetes is important to reduce the consequent metabolic abnormalities and symptoms and the incidence of long-term complications. Conventional medical and nursing practitioners often incorrectly assume that they are used to control blood glucose levels, e.g. using herbal medicines to increase insulin production or reduce insulin resistance. CT can be beneficial for people with diabetes. They can also lead to adverse events. This paper describes the outcome of monitoring complementary therapy use in our diabetic outpatient services in 2001, the results of a focus group (n=10) to explore issues identified in the monitoring process and a survey undertaken with a convenience sample of diabetes educators (n=40).

Twenty percent of patients used CT and there were three adverse events in the monitoring phase. Eight of the 10 focus group participants used CT and 16 of the diabetes educators used CT in patient care. Only one had a complementary therapy qualification.

The impact of childhood conditions and concurrent morbidities on child health and well-being

Background. Understanding the impact of illnesses and morbidities experienced by children and adolescents is essential to clinical and population health programme decision making and intervention research. This study sought to: (1) examine the population prevalence of physical and mental health conditions for children and quantify their impact on multiple dimensions of children's health and well-being; and (2) examine the cumulative effect of concurrent conditions.

Methods. We conducted a cross-sectional school-based epidemiological study of 5414 children and adolescents aged 5–18 years, and examined parental reports of child health and well-being using the parent-report Child Health Questionnaire (CHQ) PF50 13 scales are scored on a 0–100 pt scale with clinically meaningful differences of five points and the presence of childhood conditions (illnesses and health problems).

Results. Asthma, dental, vision and allergies are the most commonly identified health problems for children and adolescents, followed by attention- and behaviour-related problems (asthma 17.9–23.2%, dental 11.9–22.7%, vision 7.2–14.7%, chronic allergies 8.8–13.9%, attention problems 5.1–13.8% and behaviour problems 5.7–12.0%). As the number of concurrent health problems increase, overall health and well-being decreases substantively with mean differences in CHQ scale scores of 14 points (−7.69 to −21.51) for physical health conditions, and 28 points (−5.15 to −33.81) for mental health conditions.

Conclusions. Children's health and well-being decreases linearly with increasing presence and frequency of health problems. Having three or more conditions concurrently significantly burdens children's health and well-being, particularly for family-related CHQ domains, with a greater burden experienced for mental health conditions than physical health conditions.

Quality of life and depression among older patients waiting for joint replacement surgery

Purpose: Older patients waiting for joint replacement surgery in many western countries experience lengthy waits for their surgery. Although these patients suffer with mobility problems the nature of the disability associated with waiting for surgery is unclear. The purpose of this study was to determine health-related quality of life and symptoms of depression in persons waiting for their initial orthopaedic consultation following referral for total knee or total hip replacement surgery.

Methods: All patients who were waiting for an initial orthopaedic consultation for lower-limb joint replacement as at 25 August 2005 were surveyed. Participants were mailed questionnaires concerning demographic information, medical history, health-related quality of life (the Assessment of Quality of Life (AQoL) instrument), and symptoms of depression (Center for Epidemiologic Studies – Depression (CES-D) Scale).

Results: The 84 respondents (response rate 64%) had a mean age of 68.3 (SD 11.5 years), and 60% or respondents were women. Respondents reported an average of 1.6 (SD 0.9) medical conditions, and 85% reported osteoarthritis.} The average health-related quality of life was low (mean AQoL 0.38; SD 0.27), and near death-equivalent or worse than death-equivalent health-related quality of life (AQoL<0.1 of a maximum possible 1.0) was reported by 23% of the participants.The mean depression scale score was 16.5 (SD 11.1), and symptoms of depression (CES-D>16 of a maximum possible 60) were reported by 35% of the sample. There was a strong correlation between health-related quality of life and depression (r=–0.6).

Conclusions: Almost a third of patients waiting to see an orthopaedic surgeon about joint replacement surgery for their hip or knee had symptoms of depression. Geriatric rehabilitation services often provide interventions to these patients. The very poor quality of life reported suggests that more than exercise and strengthening will be needed to reduce disability.
