What do we know about adherence and self-care?

Despite advances in healthcare, heart failure patients continue to experience complications that could have been prevented or treated. This occurs because the only way that a therapeutic or preventive regimen can be effective, assuming that the patient's condition has been accurately diagnosed and appropriately treated, is if the patient implements self-care behaviors and adheres to the treatment regimen. However, it is widely accepted that this does not occur in many or even most instances. This article provides an overview of the current evidence related to adherence and self-care behaviors among heart failure patients and describes the state of the science on interventions developed and tested to enhance self-care maintenance in this population. Our review of literature shows that effective interventions integrate strategies that motivate, empower, and encourage patients to make informed decisions and assume responsibility for self-care. Gaps in current evidence support the need for additional research on ways to improve adherence and self-care for patients who are at an increased risk of poor adherence, including those with cognitive and functional impairments and low health literacy.     

What do we know about the state of chronic pain?

Chronic pain syndromes are characterized by altered neuronal excitability in the pain matrix. The ability to rapidly acquire and store memory of aversive events is one of the basic principles of nervous systems throughout the animal kingdom. These neuroplastic changes take place e. g. in the spinal cord, in thalamic nuclei and cortical and subcortical (limbic) areas integrating pain threshold, intensity and affective components. Chronic inflammation or injury of peripheral nerves evokes the reorganisation of cortical sensory maps. Neurons conveying nociceptive information are controlled by various sets of inhibitory interneurons. The discharge activity of these interneurons counteracts long-term changes in the pain matrix following nociceptor activation, i. e. it prevents the transition of acute pain signaling to chronic pain states. Our most recent research suggests that pain states may be sensitive to novel families of agents and therapeutic measures not predicted by traditional preclinical pain models as well as human pain states. The endogenous cannabinoid system plays a central role in the extinction of aversive memories. We propose that endocannabinoids facilitate extinction of aversive memories via their selective inhibitory effects on GABAergic networks in the amygdala.     

What do we know about the genetics of aspirin intolerance?

Although acetylsalicylic acid is prescribed for a broad range of diseases, it can induce a wide array of clinically recognized hypersensitivity reactions, including aspirin-intolerant asthma (AIA) with rhinitis and aspirin-intolerant urticaria (AIU) with anaphylaxis. Altered eicosanoid metabolism is the generally accepted mechanism of aspirin intolerance; the overproduction of cysteinyl leucotrienes has been suggested to play a causative role in both AIA and AIU. Genetic markers suggested for AIA include HLA-DPBI*0301, leucotriene C4 synthase (LTC4S), ALOX5, CYSLT, PGE2, TBXA2R and TBX21. Similarly, HLA-DB1*0609, ALOX5, FCER1A and HNMT have been identified as possible genetic markers for AIU. An additional low-risk genetic marker for AIA is MS4A2, which encodes the beta-chain of FCER1. Other single and sets of two or more interacting genetic markers are currently being investigated. Analyses of the genetic backgrounds of patients with AIA and AIU will promote the development of early diagnostic and therapeutic interventions, which may reduce the incidence of AIA and AIU.     

What can we learn about diet and physical activity from master athletes?

Only 13% of those 65 years and older engage in vigorous physical activity 3 or more days a week and obesity rates are increasing by 45% in adults over the age of 60. Physical activity helps prevent chronic disease and improves quality of life, yet few adults of any age are active. One exception is master athletes who participate in competitive sports during the middle and later years. The aerobic fitness of master athletes, as measured by maximal oxygen consumption, shows some decline, but not nearly as much as in sedentary controls. Master athletes have lipid profiles similar to those of young adults, which decreases their risk of heart disease. Master athletes also have better glucose tolerance and lower waist-to-hip ratios than sedentary adults, decreasing their risk for metabolic syndrome and type 2 diabetes. In the few dietary studies that have been conducted, master athletes consume more food energy while maintaining lower body weights than sedentary adults. Learning what motivates master athletes to stay highly active may help health professionals develop strategies to encourage exercise in the sedentary population of older adults.     

What can we do about acute extrapyramidal symptoms?

Antipsychotic drugs are the most effective treatment for psychotic disorders such as schizophrenia. However, they are known to cause a range of side-effects including acute extrapyramidal symptoms (EPS) that are both distressing and disabling. Mental health nurses play a critical role in both the detection and the management of these symptoms. A review of the literature was conducted to identify strategies for managing acute EPS. Despite a widely held belief that EPS are associated with noncompliance with medication, the data to support this hypothesis are weak. Although akathisia may negatively affect the treatment outcome, there was little evidence to suggest that parkinsonism or dystonia do. Whilst the use of anticholinergic medication may be helpful in treating acute parkinsonism and dystonia they were associated with their own side-effects and the benefit of long-term prophylactic treatment is doubtful. The literature suggests that logical prescribing and rapid detection and management of acute EPS will result in a substantial reduction in the incidence of these disabling side-effects.     

What do we know about perioperative hypersensitivity reactions and what can we do to improve perioperative safety?

Hypersensitivity reactions are an important aspect of perioperative care and are a crucial interdisciplinary issue in anaesthesiological practice, as well as allergological and laboratory diagnostics. This phenomenon was observed as early as the 1980s and 1990s in Western European countries, and knowledge on this subject has grown significantly over time. Although hypersensitivity reactions are not frequent events (the incidence of perioperative hypersensitivity reactions ranges from 1:386 to 1:13 000 procedures, with higher frequency − 1 per 6500 general anaesthesias with neuromuscular blocking agents administrations), their courses are unfortunately serious and life-threatening. It should also be noted that there is no information regarding the occurrence of perioperative hypersensitivity reactions in many countries. Hence, global assessment of the problem is underestimated. The primary source of actual knowledge comes from epidemiological studies, which indicate an increasing frequency of hypersensitivity reaction occurrence and changes in aetiological factors. The first report from France (1984 to 1989) described two main causes – neuromuscular blocking agents and hypnotic agents. The following years confirmed an increase in perioperative hypersensitivity reactions associated with latex and antibiotics. The most recent data from the National Audit Project 6 indicated increased participation of antibiotics, chlorhexidine, and contrast agents. The results of epidemiological analyses are the basis of medical management guidelines and practice modification. Thanks to the activity of many organisations monitoring the intensity and nature of perioperative hypersensitivity reactions, guidelines for diagnostics and management have been developed. This article presents the results of numerous studies, including the first and the most recent, from various geographical regions. The clinical significance, pathogenesis mechanisms are also discussed. This publication also presents important directions for further scientific and epidemiological research on perioperative hypersensitivity reactions.

Key messages

• The incidence of perioperative hypersensitivity reactions ranges from 1:386 to 1:13 000 procedures, with higher frequency – 1 per 6500 general anaesthesias with neuromuscular blocking agents administrations.
• Reactions may occur during the first episode of anaesthesia, most frequently in the induction of general anaesthesia, and much less frequently during postoperative follow-up.
• The first reports of perioperative hypersensitivity reaction come from the 1990s, and knowledge on this subject has grown significantly over time.
• In many countries, multidisciplinary teams and organisations have been established to identify, monitor the occurrence of this phenomenon, and have set the directions of medical activities and have changed the rules and recommendations.
• There is no information about the occurrence of perioperative hypersensitivity reactions in many countries, and global assessment of the problem is underestimated. Additionally, there is a great need to develop a system to monitor their occurrence in other countries.
• The long-term epidemiologic studies have demonstrated variability in pharmacologic triggers. However, the main pharmacological substances (antibiotics, muscle relaxants, disinfectans, contrast agents) are related to aspects of patient safety during anaesthesia.

     

What do we know about the prevalence of pain caused by malignancy?

BACKGROUND: Since there is no epidemiologic assessment of the frequency of pain caused by tumor in Germany, tumor-pain-prevalence is estimated indirectly on the basis of mortality and median survival. Knowing that about 50% of all patients having metastases or incurable locoregional recurrence suffer from pain every day, the product of median survival times mortality was calculated to achieve the number of patients' days with tumor-caused pain per year (82,710,690 days in Germany 1995). By division with 365 (days), it is calculated that 226,605 patients require tumor pain related treatment at one day in Germany. Another calculation based on Bonica's publications that 60-90% of patients suffering from advanced cancer are having pain and based on an estimated tumor prevalence 1989/90 revealed a tumor pain prevalence of 221,826. DISCUSSION: Thus both methods result in the estimation, that about 220,000 patients require tumor-pain-related treatment at one day in Germany.     

What do we think about them and what do they think about us? Social representations of interprofessional and interorganizational collaboration in the welfare sector

Professionals in healthcare, social services, and schools often collaborate when addressing children and adolescents with complex psychosocial needs. Based on theory of social representations, we investigated how professionals in the mentioned organizations perceived each other through their experiences of collaboration. Twenty-nine unit managers and 35 staff members were interviewed in 12 focus groups, and the data collected were subjected to content analysis. Most social representations indicated complex and problematic interprofessional collaboration, although some were positive in nature. We also found social representations regarding ignorance of each other’s organizations, distrust, unavailability, and uncommunicativeness. Conceptions of the other party’s way of thinking appeared to include adverse attitudes and low expectations from the other side. Concurrently, there was mutual understanding of the limited room to maneuver and heavy workloads. The professionals’ perceptions reflected frustration and ambivalence, and also indicated that dialogue was prevented by established boundaries and low expectations. We conclude that arenas are needed for productive dialogue and exchange of relevant knowledge in such collaborative systems, and that management should enable staff to collaborate based on the existing boundaries.
