Voluntary stopping of eating and drinking in Switzerland from different points of view : protocol for a mixed-methods study

“To die with dignity” has reached the significance of a core value in democratic societies. Based on this unconditional value, people require autonomy and care. "Voluntary stopping of eating and drinking" (VSED) represents an alternative to assisted suicide because no one else is involved in the action of death fastening, even though from outside, it might be considered as an extreme form of passive euthanasia. However, there are no data available about the prevalence and frequency of either explicit VSED or the implicit reduction of food and liquid in Switzerland. The responsible and independent ethics committee of the Greater Region of Eastern Switzerland (EKOS 17/083) approved this study

Barriers and enablers in the management of tuberculosis treatment in Addis Ababa, Ethiopia: a qualitative study

Tuberculosis (TB) is an infectious disease which causes about two million deaths each year. In 1993, the World Health Organization (WHO) declared TB to be a “Global Emergency” due to an increasing number of TB cases and a rise in multidrug resistant cases in the developed world. Treatment interruption was considered one of the major challenges. WHO introduced the current TB control program DOTS (directly observed treatment, short course) as the tool to control the disease. To prevent further development of resistance against anti-TB drugs it was decided to observe each patient taking their daily dose of medication. The overall aim of this thesis is to explore how patients and health workers perceive and manage TB symptoms and treatment in a high-endemic and a low-endemic setting in the era of DOT(S). The data is based on fieldwork, including in-depth interviews and focus groups with TB patients and health workers, in Addis Ababa, Ethiopia (2001-2002) and in Oslo/Akershus, Norway (2007-2008). We found that people’s interpretation and management of TB symptoms is influenced by cultural, social and economic factors. TB was, in both contexts, associated with poverty, and subsequently with a disease that affects certain countries or certain segments of a population. TB was viewed as a severe disease in both contexts, but there was variation between individuals to what extent one considered oneself as a likely victim. In the absence of circumstantial causes, such as poverty, patients in a lowendemic setting like Norway, found it difficult to understand why they had developed the disease. There was scarce knowledge about the fact that the disease could be latent. Awareness of early symptoms, such as persistent cough, was low in both contexts. Perceptions of vulnerability, together with the presence or absence of socio-economic barriers or enablers influenced at what time patients would seek help. The study suggests that health personnel lacked awareness or misinterpreted early symptoms of TB. In Ethiopia, lay categorizations of early TB symptoms converged with diagnostic practices in parts of the professional health sector. The diagnostic process could endure for many months after patients’ first contact with the health services. Similarly, in Norway, we found that patients’ interpretations of early symptoms often were confirmed in the meeting with health personnel. The consequences were prolonged diagnostic processes. The study shows that patients’ ability to manage TB treatment is a product of dynamic processes, in which social and economic costs and other burdens interplay over time. A decision to interrupt treatment can be shaped by past struggles and accrued costs; in which seems financially, socially or emotionally unbearable at the moment of treatment interruption. The burdens related to DOT could also be significant, in patients who did not interrupt treatment. Patients in both Ethiopia and Norway experienced an authoritarian and rigid practice of DOT, which made it difficult to simultaneously attend to demands related to treatment and demands related to other areas of life. The most vulnerable patients, such as those without permanent jobs, suffered from high economic, social and emotional costs. In conclusion, health personal need more knowledge about typical and atypical symptoms of TB. In low-endemic settings doctors need to be trained to adjust their level of suspicion to the migration history of the patient. In high-endemic settings one should be aware that health personnel may understand and manage TB within a traditional perspective. Patients in both high- and low-endemic contexts need concrete information about the cause of TB, how it is transmitted, how symptoms can be manifested, how the disease can progress and how it can be cured. The study indicates that inequalities that predispose for TB may be reinforced in the patient’s interaction with the health services due to a rigid, disempowering practice of DOT. Subsequently, DOT per se may add to the chain of structural barriers that patients have to overcome to access and complete treatment. To ensure that TB patients complete treatment one must address the coexisting and interacting crises that follow a TB diagnosis. This could require TB programs to adopt a more holistic approach. Measures that secure early diagnosis may reduce some of the physical, psycho-social and economic costs patients face while undergoing treatment. Measures that empower patients to participate in their own health care may avoid disempowering and humiliating practices

Productive resistance within the public sector: exploring organisational culture

The article examines how South Korean civil servants responded to the introduction of pay for performance. Drawing upon 31 in-depth interviews with career civil servants, it identifies what became known as 1/n, a form of ‘discreet resistance’ that emerged and evolved. The analytical framework allows productive resistance to be seen as ebbing and flowing during organisational change that sees institutionalisation, deinstitutionalisation and re-institutionalisation. In understanding the cultural context of organisational resistance the contribution is three-fold. First, a nuanced definition and understanding of productive resistance. Second, it argues that productive resistance must be seen as part of a process that does not simply reflect ‘offer and counter-offer’ within the change management process. Thirdly, it identifies differences within groups and sub-cultures concerning commitment towards resistance and how these fissures contribute towards change as new interpretive schemes and justifications are presented in light of policy reformulations

Macrophages in Breast Cancer: Do Involution Macrophages Account for the Poor Prognosis of Pregnancy-Associated Breast Cancer?

Macrophage influx is associated with negative outcomes for women with breast cancer and has been demonstrated to be required for metastasis of mammary tumors in mouse models. Pregnancy-associated breast cancer is characterized by particularly poor outcomes, however the reasons remain obscure. Recently, post-pregnancy mammary involution has been characterized as having a wound healing signature. We have proposed the involution-hypothesis, which states that the wound healing microenvironment of the involuting gland is tumor promotional. Macrophage influx is one of the prominent features of the involuting gland, identifying the macrophage a potential instigator of tumor progression and a novel target for breast cancer treatment and prevention

Deciphering the pathogenesis of tendinopathy: a three-stages process

Our understanding of the pathogenesis of "tendinopathy" is based on fragmented evidences like pieces of a jigsaw puzzle. We propose a "failed healing theory" to knit these fragments together, which can explain previous observations. We also propose that albeit "overuse injury" and other insidious "micro trauma" may well be primary triggers of the process, "tendinopathy" is not an "overuse injury" per se. The typical clinical, histological and biochemical presentation relates to a localized chronic pain condition which may lead to tendon rupture, the latter attributed to mechanical weakness. Characterization of pathological "tendinotic" tissues revealed coexistence of collagenolytic injuries and an active healing process, focal hypervascularity and tissue metaplasia. These observations suggest a failed healing process as response to a triggering injury. The pathogenesis of tendinopathy can be described as a three stage process: injury, failed healing and clinical presentation. It is likely that some of these "initial injuries" heal well and we speculate that predisposing intrinsic or extrinsic factors may be involved. The injury stage involves a progressive collagenolytic tendon injury. The failed healing stage mainly refers to prolonged activation and failed resolution of the normal healing process. Finally, the matrix disturbances, increased focal vascularity and abnormal cytokine profiles contribute to the clinical presentations of chronic tendon pain or rupture. With this integrative pathogenesis theory, we can relate the known manifestations of tendinopathy and point to the "missing links". This model may guide future research on tendinopathy, until we could ultimately decipher the complete pathogenesis process and provide better treatments

Phagocytosis Escape by a Staphylococcus aureus Protein That Connects Complement and Coagulation Proteins at the Bacterial Surface

Upon contact with human plasma, bacteria are rapidly recognized by the complement system that labels their surface for uptake and clearance by phagocytic cells. Staphylococcus aureus secretes the 16 kD Extracellular fibrinogen binding protein (Efb) that binds two different plasma proteins using separate domains: the Efb N-terminus binds to fibrinogen, while the C-terminus binds complement C3. In this study, we show that Efb blocks phagocytosis of S. aureus by human neutrophils. In vitro, we demonstrate that Efb blocks phagocytosis in plasma and in human whole blood. Using a mouse peritonitis model we show that Efb effectively blocks phagocytosis in vivo, either as a purified protein or when produced endogenously by S. aureus. Mutational analysis revealed that Efb requires both its fibrinogen and complement binding residues for phagocytic escape. Using confocal and transmission electron microscopy we show that Efb attracts fibrinogen to the surface of complement-labeled S. aureus generating a ‘capsule’-like shield. This thick layer of fibrinogen shields both surface-bound C3b and antibodies from recognition by phagocytic receptors. This information is critical for future vaccination attempts, since opsonizing antibodies may not function in the presence of Efb. Altogether we discover that Efb from S. aureus uniquely escapes phagocytosis by forming a bridge between a complement and coagulation protein
