Human schistosomiasis mansoni: studies on in vitro granuloma modulation

Infection with Schistosoma mansoni induces humoral and T cell mediated responses and leads to delayed hipersensitivity that results in granulomatous inflamatory disease around the parasite eggs. Regulation of these responses resulting in a reduction in this anti-egg inflamatory disease is appsrently determined by idiotypic repertoires of the patient, associated with genetic background and multiple external factors. We have previously reported on idiotype/anti-idiotype-receptor transactions in clinical human schistosomiasis. These findings support a hypothesis that anti-SEA cross-reactive idiotypes develop in some patients during the course of a chronic infection and participate in regulation of anti-SEA cellular immune responses. We repport here on experiments wich extend those observations to the regulation of granulomatous hypersensitivity measured by an in vitro granuloma model. T cells from chronic intestinal schistosomiasis patients were stimulated in vitro with anti-SEA idiotypes and assayed in an autologous in vitro granuloma assay for modulation of granuloma formation. These anti-SEA idiotype reactive T cells were capable of regulating autologous in vitro granuloma formation. This regulatory activity, initiated with stimulatory anti-SEA idiotypic antibodies, was antigenically specific and was dependent on the present of intact (F(ab')2 immunoglobulin molecules. The ability to elicit this regulatory activity appears to be dose dependent and is more easily demonstrated in chronically infected intestinal patients or SEA sensitized individuals. These data support the hypothesis that anti-SEA cross reactive idiotypes are important in regulating granulomatous hypersensitivy in chronic intestinal schistosomiasis patients and these cross-reactive idiotypes appear to play a major role in cell-cell interactions which result in the regulation of anti-SEA cellular immune responses

Franchises lost and gained: post-coloniality and the development of women’s rights in Canada

The Canadian constitution is to some extent characterised by its focus on equality, and in particular gender equality. This development of women’s rights in Canada and the greater engagement of women as political actors is often presented as a steady linear process, moving forwards from post-enlightenment modernity. This article seeks to disturb this ‘discourse of the continuous,’ by using an analysis of the pre-confederation history of suffrage in Canada to both refute a simplistic linear view of women’s rights development and to argue for recognition of the Indigenous contribution to the history of women’s rights in Canada. The gain of franchise and suffrage movements in Canada in the late nineteenth and early twentieth century are, rightly, the focus of considerable study (Pauker 2015), This article takes an alternative perspective. Instead, it examines the exercise of earlier franchises in pre-confederation Canada. In particular it analyses why franchise was exercised more widely in Lower Canada and relates this to the context of the removal of franchises from women prior to confederation

Effects of Anacetrapib in Patients with Atherosclerotic Vascular Disease

BACKGROUND: Patients with atherosclerotic vascular disease remain at high risk for cardiovascular events despite effective statin-based treatment of low-density lipoprotein (LDL) cholesterol levels. The inhibition of cholesteryl ester transfer protein (CETP) by anacetrapib reduces LDL cholesterol levels and increases high-density lipoprotein (HDL) cholesterol levels. However, trials of other CETP inhibitors have shown neutral or adverse effects on cardiovascular outcomes. METHODS: We conducted a randomized, double-blind, placebo-controlled trial involving 30,449 adults with atherosclerotic vascular disease who were receiving intensive atorvastatin therapy and who had a mean LDL cholesterol level of 61 mg per deciliter (1.58 mmol per liter), a mean non-HDL cholesterol level of 92 mg per deciliter (2.38 mmol per liter), and a mean HDL cholesterol level of 40 mg per deciliter (1.03 mmol per liter). The patients were assigned to receive either 100 mg of anacetrapib once daily (15,225 patients) or matching placebo (15,224 patients). The primary outcome was the first major coronary event, a composite of coronary death, myocardial infarction, or coronary revascularization. RESULTS: During the median follow-up period of 4.1 years, the primary outcome occurred in significantly fewer patients in the anacetrapib group than in the placebo group (1640 of 15,225 patients [10.8%] vs. 1803 of 15,224 patients [11.8%]; rate ratio, 0.91; 95% confidence interval, 0.85 to 0.97; P=0.004). The relative difference in risk was similar across multiple prespecified subgroups. At the trial midpoint, the mean level of HDL cholesterol was higher by 43 mg per deciliter (1.12 mmol per liter) in the anacetrapib group than in the placebo group (a relative difference of 104%), and the mean level of non-HDL cholesterol was lower by 17 mg per deciliter (0.44 mmol per liter), a relative difference of -18%. There were no significant between-group differences in the risk of death, cancer, or other serious adverse events. CONCLUSIONS: Among patients with atherosclerotic vascular disease who were receiving intensive statin therapy, the use of anacetrapib resulted in a lower incidence of major coronary events than the use of placebo.

Barriers to Instructional Technology Use Among Malaysian Public University Academicians

Despite the benefits of technology use in instruction, in general it has not been widely accepted within institutions of higher education in both developed and developing nations. Previous studies have indicated that its use by faculty members in higher education has been generally minimal. This study examined: i) the nature and extent of use of certain instructional technologies by university lecturers, and ii) reasons that has hindered the utilization of instructional technologies by lecturers in a Malaysian public university. The findings of the study revealed that despite the growing availability of newer technologies and the greater familiarity with technologies by faculty members, they reportedly continue to rely on the more familiar technologies (such as audiovisual media and word processing) for their class instruction. The widespread use of the newer and more innovative technologies (such as presentation software, computer conferencing, distance learning technologies and multimedia technologies) by the lecturers seems to be occurring at a slow rate. On the basis of the responses to reasons for not using a instructional technology, the primary reasons most frequently reported by were unavailability of facilities or resources, technology not necessary, lack of knowledge and skills, and lack of time

A qualitative study exploring patient, family carer and healthcare professionals’ direct experiences and barriers to providing and integrating palliative care for advanced head and neck cancer

Objectives: To report on direct experiences from advanced head and neck cancer patients, family carers and healthcare professionals, and the barriers to integrating specialist palliative care. Methods: Using a naturalistic, interpretative approach, within Northwest England, a purposive sample of adult head and neck cancer patients was selected. Their family carers were invited to participate. Healthcare professionals (representing head and neck surgery and specialist nursing; oncology; specialist palliative care; general practice and community nursing) were recruited. All participants underwent face-to-face or telephone interviews. A thematic approach, using a modified version of Colazzi’s framework, was used to analyze the data. Results: Seventeen interviews were conducted (9 patients, 4 joint with family carers and 8 healthcare professionals). Two main barriers were identified by healthcare professionals: “lack of consensus about timing of Specialist Palliative Care engagement” and “high stake decisions with uncertainty about treatment outcome.” The main barrier identified by patients and family carers was “lack of preparedness when transitioning from curable to incurable disease.” There were 2 overlapping themes from both groups: “uncertainty about meeting psychological needs” and “misconceptions of palliative care.” Conclusions: Head and neck cancer has a less predictable disease trajectory, where complex decisions are made and treatment outcomes are less certain. Specific focus is needed to define the optimal way to initiate Specialist Palliative Care referrals which may differ from those used for the wider cancer population. Clearer ways to effectively communicate goals of care are required potentially involving collaboration between Specialist Palliative Care and the wider head and neck cancer team
