Views of general practitioners and pharmacists on the role of the pharmacist in HIV/Aids management

Background Sub-Saharan Africa is home to 25.8 million people living with HIV/Aids. In November 2003, the South African government approved The Operational Plan for Comprehensive Treatment and Care for HIV and Aids, which aimed to provide antiretroviral treatment to 500 000 patients by the end of 2007. The successful implementation of this operational plan requires many healthcare providers trained in aspects of HIV. This study aimed to establish and compare the views of general practitioners and pharmacists on the role of the pharmacist in HIV/Aids management and to elucidate an appropriate role for pharmacists. Ethical approval was obtained from the MEDUNSA Research Ethics and Publications Committee.MethodsThe study population consisted of general practitioners in the province of Gauteng and community pharmacists in Gauteng and the Western Cape. Two hundred medical practitioners were selected at random from the 7 157 registered in Gauteng. Pharmacist respondents (293 from 879 community pharmacies in Gauteng and 200 from 493 in the Western Cape respectively) were selected randomly. The respondents were contacted individually by telephone and asked to complete a pilot-tested 10-statement questionnaire on their views of aspects relating to a role for pharmacists in HIV/Aids management.ResultsMean values for positive responses were calculated and analysed (two-sided t test). The response rates for general practitioners and pharmacists were 44.5% and 38.1% respectively. The responses were grouped into two categories, dispensing and advice and testing and treatment. Both groups agreed about the dispensing and advice category. Of the general practitioners surveyed, 95.5% agreed that pharmacists should counsel patients on the correct use of medications and 100% agreed that the pharmacist should be aware of all related side effects and drug interactions of HIV medications, i.e. the general practitioners were comfortable with pharmacists providing a dispensing and advisory role. The groups differed significantly about the testing and treatment category.ConclusionGPs were generally not in favour of pharmacists being involved in the testing and treatment of HIV/Aids. The pharmacists surveyed, on the other hand, indicated their willingness to assume an expanded role in HIV/Aids management. A potential role for pharmacists was elucidated. It complements the role of the pharmacist in HIV/Aids management described in the South African Pharmacy Council Position Paper. The differences in views identified in the survey hold serious implications as South Africa struggles to contend with the HIV/Aids epidemic.For full text, click here:SA Fam Pract 2006;(7):14-14

Remarks on Causality in Relativistic Quantum Field Theory

It is shown that the correlations predicted by relativistic quantum field theory in locally normal states between projections in local von Neumann algebras \cA(V_1),\cA(V_2) associated with spacelike separated spacetime regions $V_1,V_2$ have a (Reichenbachian) common cause located in the union of the backward light cones of $V_1$ and $V_2$. Further comments on causality and independence in quantum field theory are made.Comment: 10 pages, Latex, Quantum Structures 2002 Conference Proceedings submission.

Two roles of relativistic spin operators

Operators that are associated with several important quantities, like angular momentum, play a double role: they are both generators of the symmetry group and ``observables.'' The analysis of different splittings of angular momentum into "spin" and "orbital" parts reveals the difference between these two roles. We also discuss a relation of different choices of spin observables to the violation of Bell inequalities.Comment: RevTeX 4, 4 pages A discussion on relation of different choices of spin observables to the observed violation of Bell inequalities is added, some misprints corrected and the presentation is clarifie

Reichenbach's Common Cause Principle in Algebraic Quantum Field Theory with Locally Finite Degrees of Freedom

In the paper it will be shown that Reichenbach's Weak Common Cause Principle is not valid in algebraic quantum field theory with locally finite degrees of freedom in general. Namely, for any pair of projections A and B supported in spacelike separated double cones O(a) and O(b), respectively, a correlating state can be given for which there is no nontrivial common cause (system) located in the union of the backward light cones of O(a) and O(b) and commuting with the both A and B. Since noncommuting common cause solutions are presented in these states the abandonment of commutativity can modulate this result: noncommutative Common Cause Principles might survive in these models

Directed assembly of optically bound matter

We present a study of optically bound matter formation in a counter-propagating evanescent field, exploiting total internal reflection on a prism surface. Small ensembles of silica microspheres are assembled in a controlled manner using optical tweezers. The structures and dynamics of the resulting optically bound chains are interpreted using a simulation implementing generalized Lorentz-Mie theory. In particular, we observe enhancement of the scattering force along the propagation direction of the optically bound colloidal chains leading to a microscopic analogue of a driven pendulum which, at least superficially, resembles Newton’s cradle

Parasitic helminth infections and the control of human allergic and autoimmune disorders

The profile of global health today presents a striking reciprocal distribution between parasitic diseases in many of the world’s lower-income countries, and ever-increasing levels of inflammatory disorders such as allergy, autoimmunity and inflammatory bowel diseases in the more affluent societies. Attention is particularly focused on helminth worm parasites, which are associated with protection from allergy and inflammation in both epidemiological and laboratory settings. One mechanistic explanation of this is that helminths drive the regulatory arm of the immune system, abrogating the ability of the host to expel the parasites, while also dampening reactivity to many “bystander” specificities. Interest has therefore heightened into whether helminth parasites, or their products, hold therapeutic potential for immunological disorders of the developed world. In this narrative review, progress across a range of trials is discussed, together with prospects for isolating individual molecular mediators from helminths that may offer defined new therapies for inflammatory conditions

Thin endometrial lining during frozen embryo cycles: a case-control study of risk factors and natural history

Objective: To identify predictors of thin endometrial lining in the first frozen embryo transfer cycles and to characterize the natural history of this condition over subsequent cycles. Design: Retrospective case-control study Conclusions: This study shows that prognosis after a diagnosis of thin endometrial lining is favorable. Lower weight and thinner fresh cycle lining are predictors of thin endometrial lining in FET cycles. Most importantly, women with a diagnosis of thin endometrial lining have similar live birth rates as those with adequate endometrial lining, although their time to achieve live birth is slightly longer

Unpacking estimates of task duration: The role of typicality and temporality

Research in task duration judgment has shown that unpacking a multifaceted task into components prior to estimating its duration increases estimates. In three studies, we find that unpacking a complex task can increase, decrease, or leave unaffected task duration estimates depending on the typicality of the unpacked components and their temporal position in the task sequence. Unpacking atypical long components increases task duration estimates, while unpacking atypical short components decreases estimates (Study 1). Unpacking atypical early components increases task duration estimates, while unpacking atypical late components decreases estimates (Study 2). Unpacking typical early or late components leaves estimates unaffected (Study 3). We explain these results based on the idea that task duration estimation involves a mental simulation process, and by drawing on theories of unpacking in probability judgment that emphasize the role of the typicality of the unpacked components. These findings hint at a deep conceptual link between probability judgment and task duration estimation but also show differences, such as the influence that temporality exerts on estimated duration. © 2013 Elsevier Inc
