Western Hindus and 'Global Hinduism' - Discourses on Conversion to 'Hindu-Religions', Acceptance of Converts and Social Engagement

The paper deals with the problem of (the often supposedly impossible) conversion to “Hinduism”. I start with an outline of what I call the ‘no conversion possible’ paradigm, and briefl y point to the lack of refl ection on acceptance of converts in most theories of religious conversion. Then, two examples are presented: Firstly, I consider conversion to ISKCON and the discourse on the Hare Krishna movement’s Hinduness. Secondly, I give a brief outline of the globalsanatana dharmamovement as inaugurated by Satguru Siva Subramuniyaswami, a converted American Hindu based in Hawai’i. In the conclusion, I refl ect on (civic) social capital and engagement in global networks as a means to gain acceptance as converts to Hinduism. I argue in line with Stepick, Rey and Mahler (2009) that the religious movements’ civic engagement (in these cases engagement in favour of the Indian diasporic communities and of Hindus in India) provides a means for the individual, non-Indian converts to acquire the social capital that is necessary for gaining acceptance as ‘Hindus’ in certain contexts.

Intratumoral budding is preoperative biopsies predicts local and distant metastasis in colorectal cancer patients

Objective: In 2011, the term “intratumoral budding, ITB” was used to describe the presence of tumor buds within the main tumor body and was correlated to worse clinical outcome in colorectal cancer patients. Here, we further elucidate the potential clinical role of ITB in pre-operative biopsies using pan-cytokeratin stained tissues and a quantitative scoring system. Method: 139 pre-operative biopsies from patients with colorectal cancer underwent immunohistochemistry for pancytokeratin (AE1/AE3). ITB were counted in the area of densest budding (40×) and classified as high-grade when >10 buds/HPF were observed based on receiver operating characteristic (ROC) curve analysis. Results: High-grade ITB occurred in 26.6 % of cases and was associated with right-sided tumor location (p=0.0356), more advanced pT (p=0.0198) and pN (p<0.0001) classifications, distant metastasis (p=0.0164), higher tumor grade (p=0.0037) and lymphatic invasion (p=0.0445). The specificity and positive predictive value for lymph node metastasis was 86.7 % and 75.6 %, respectively. Disease-free survival was significantly worse in patients with high-grade ITB (5-year survival=25 %) in comparison to patients with low-grade ITB (5-year survival=55 %) (p=0.0157). Conclusion: The assessment of ITB in pre-operative biopsies is predictive of local and distant metastasis in corresponding resections and should be considered in daily management of colorectal cancer patients.

Effects of thoracic epidural anesthesia on hemodynamics and global oxygen transport in ovine endotoxemia

Besides providing effective analgesia, thoracic epidural anesthesia (TEA) has been shown to decrease perioperative morbidity and mortality. Because of its vasodilatory properties in association with the sympathetic blockade, however, TEA may potentially aggravate cardiovascular dysfunctions resulting from sepsis and systemic inflammatory response syndrome. The objective of the present study was to assess the effects of TEA on hemodynamics, global oxygen transport, and renal function in ovine endotoxemia. After a baseline measurement in healthy sheep (n = 18), Salmonella typhosa endotoxin was centrally infused at incremental doses to induce and maintain a hypotensive-hypodynamic circulation using an established protocol. The animals were then randomly assigned to one of two groups. In the treatment group, continuous TEA was initiated with 0.1 mL.kg of 0.125% bupivacaine at the onset of endotoxemia and maintained with 0.1 mL.kg.h. In the control group, the same amount of isotonic sodium chloride solution was injected through the epidural catheter. In the animals surviving the entire experiment (n = 7 per group), cardiac index and mean arterial pressure decreased in a dose-dependent manner during endotoxin infusion. In the TEA group, neither systemic hemodynamics nor global oxygen transport were impaired beyond the changes caused by endotoxemia itself. Urinary output was increased in the TEA group as compared with the control group (P < 0.05). In this model of endotoxic shock, TEA improved renal perfusion without affecting cardiopulmonary hemodynamics and global oxygen transport.

The influence of local and systemic preconditioning on oxygenation, metabolism and survival in critically ischaemic skin flaps in pigs

Stress proteins represent a group of highly conserved intracellular proteins that provide adaptation against cellular stress. The present study aims to elucidate the stress protein-mediated effects of local hyperthermia and systemic administration of monophosphoryl lipid A (MPL) on oxygenation, metabolism and survival in bilateral porcine random pattern buttock flaps. Preconditioning was achieved 24h prior to surgery by applying a heating blanket on the operative site (n = 5), by intravenous administration of MPL at a dosage of 35 microg/kg body weight (n = 5) or by combining the two (n = 5). The flaps were monitored with laser Doppler flowmetry, polarographic microprobes and microdialysis until 5h postoperatively. Semiquantitative immunohistochemistry was performed for heat shock protein 70 (HSP70), heat shock protein 32 (also termed haem oxygenase-1, HO-1), and inducible nitrc oxide synthase (iNOS). The administration of MPL increased the impaired microcirculatory blood flow in the proximal part of the flap and partial oxygen tension in the the distal part by approximately 100% each (both P<0.05), whereas both variables remained virtually unaffected by local heat preconditioning. Lactate/pyruvate (L/P) ratio and glycerol concentration (representing cell membrane disintegration) in the distal part of the flap gradually increased to values of approximately 500 mmol/l and approximately 350 micromol/l, respectively (both P<0.01), which was substantially attenuated by heat application (P<0.01 for L/P ratio and P<0.05 for glycerol) and combined preconditioning (P<0.01 for both variables), whereas the effect of MPL was less marked (not significant). Flap survival was increased from 56% (untreated animals) to 65% after MPL (not significant), 71% after heat application (P<0.05) and 78% after both methods of preconditioning (P<0.01). iNOS and HO-1 were upregulated after each method of preconditioning (P<0.05), whereas augmented HSP70 staining was only observed after heat application (P<0.05). We conclude that local hyperthermia is more effective in preventing flap necrosis than systemic MPL administration because of enhancing the cellular tolerance to hypoxic stress, which is possibly mediated by HSP70, whereas some benefit may be obtained with MPL due to iNOS and HO-1-mediated improvement in tissue oxygenation.

Long-term effects of heart transplantation: the gap between physical performance and emotional well-being

The purpose of our study was to assess physical and emotional factors in heart transplant patients. A prospective design was used to compare patients' physical symptoms, emotional complaints, and restrictions at admission to the waiting list, immediately after, and 1 and 5 years after heart transplantation. Thirty-three patients were included (30 male, 3 female) in the study. Their mean age at admission was 48 +/- 10.2 years. Of these, 23 suffered from cardiomyopathy, 8 from coronary heart disease, and 2 from valvular insufficiency. At admission, the patients suffered from symptoms of cardiac insufficiency, and were restricted in sports, gardening, hobbies, sexual life, job, food-intake, and mobility. More than three-fourths rated their physical and emotional status as moderate to poor. Emotionally, they suffered from irritability, restlessness, depression, psychic lability, lowered drive, lack of social contact, low self-esteem, and anxiety. At the end of rehabilitation (4-8 weeks after the operation), all physical and emotional complaints, as well as restrictions had significantly decreased (p < 0.0001 to p < 0.001), except for trembling, numbness of hands/feet, and food-intake. One year postoperatively, patients reported even fewer physical complaints (p < 0.01). Three-fourths rated their physical and emotional status good or excellent. Five years postoperatively--in contrast to physical status, restrictions, and physical complaints--the emotional complaints had increased significantly (p < 0.0001). Patients reported excellent physical performance up to 5 years postoperatively. On the other hand, the study revealed that their emotional well-being had significantly deteriorated from 1 to 5 years postoperatively. Attention should, therefore, not only be paid to the good physical health of the survivors, but also to the worsening of their emotional status.
