If I had not been asked to read this book, I would not havepicked it off the shelf, despite my interest in women’shealth. The two reasons for this were the cover and the title.I’m ashamed to admit that ‘A Life     

Pharmacokinetic characterization in xenografted mice of a series of first-generation mimics for HLA-DR antibody, Lym-1, as carrier molecules to image and treat lymphoma.

Despite their large size, antibodies (Abs) are suitable carriers to deliver systemic radiotherapy, often molecular image-based, for lymphoma and leukemia. Lym-1 Ab has proven to be an effective radioisotope carrier, even in small amounts, for targeting human leukocyte antigen DR (HLA-DR), a surface membrane protein overexpressed on B-cell lymphoma. Pairs of molecules (referred to as ligands), shown by computational and experimental methods to bind to each of 2 sites within the Lym-1 epitopic region, have been linked to generate small (<2 kDa) molecules (referred to as selective high-affinity ligands [SHALs]) to mimic the targeting properties of Lym-1 Ab. METHODS: A lysine-polyethylene glycol (PEG) backbone was used to synthetically link 2 of the following ligands: deoxycholate, 5-leuenkephalin, triiodothyronine, thyronine, dabsyl-L-valine, and N-benzoyl-L-arginyl-4-amino-benzoic acid to generate a series of 13 bidentate SHALs with a biotin or 1,4,7,10-tetraazacyclododecane-N,N',N',N'-tetraacetic acid (DOTA) chelate attached to the linker. These SHALs have been assessed for their selectivity in binding to HLA-DR10-expressing cells and for their pharmacokinetics and tissue biodistribution in mice. Biotinylated versions of these SHALs discriminated cell lines positive for HLA-DR10 expression with near-nanomolar affinity. The DOTA versions of 4 SHALs were labeled with (111)In for pharmacokinetic studies in mice with HLA-DR10-expressing malignant Raji xenografts. RESULTS: The bidentate, biotinylated, and DOTA-SHALs were synthesized in high-purity, multimilligram amounts. Mean radiochemical and product yields and purities were 90%, 75%, and 90% at mean specific activities of 3.9 MBq/microg (105 microCi/microg) for the (111)In-labeled SHALs. As expected, rapid blood clearance and tumor targeting were observed. The pharmacokinetics of the SHALs was influenced by the component ligands. Biliary clearance, kidney localization, and serum receptor binding contributed to less favorable tumor targeting. CONCLUSION: A series of SHALs was readily synthesized in multimilligram amounts and showed the expected selective binding in vitro. Better selection of the SHAL components should provide second-generation SHALs with improved properties to fulfill the substantial potential of these novel molecular carriers for targeting.     

Endocrinology: Predictive value of serum oestradiol concentrations and oocyte number in severe ovarian hyperstimulation syndrome

Ovarian hyperstimulation syndrome (OHSS) is a serious complicationof gonadotrophin usage but it is difficult to accurately predictits occurrence. Previous investigators have identified the combinationof high oestradiol concentrations and oocyte number as beingpredictive in 80% of cases. In this study we sought to identifythe incidence of severe OHSS in patients with high oestradiolconcentrations and large numbers of oocytes and to evaluatethe importance of pregnancy in the development of OHSS. Between1990 and 1993, we studied 139 cycles using two assisted reproductivetechniques [oocyte donor, n =72; in-vitro fertilization (IVF),n = 67] in which either oestradiol (>4000 pg/ml), oocytenumber (>25), or both were elevated. OHSS was diagnosed bystandard criteria. There were no cases of severe OHSS in theoocyte donor group and six in the IVF group. Among 10 patientswith oestradiol concentration >6000 pg/ml and >30 oocytes,only one had OHSS (10%). The relative risk of OHSS with pregnancywas 12 (confidence interval 2.18–66.14). We conclude thatthe risk of OHSS even at high levels of stimulation is lowerthan previously believed. Secondly, donors have a very low riskof OHSS, probably because of the absence of pregnancy. As such,cryopreservation of all oocytes in IVF cycles is a reasonablealternative to cycle cancellation or use of adjunctive medication.     

Evaluating clinical educators: an employer's perspective

An Australian school of nursing's attempt to introduce an evaluation process required by management for clinical educators involved in undergraduate preregistration education is discussed Reliance on student feedback and clinical agencies' perceptions of the quality of teaching were seen as inadequate mechanisms for evaluation The evaluation process adopted incorporated observation of the educators together with self-reflection on their performance We conclude that post-briefings were poorly used and generally not reflective Educators relied heavily on their clinical skills and used a limited range of teaching strategies Whilst evaluation of clinical educators was time consuming and therefore costly, it is argued that it is essential to the integrity of the course The evaluation process has provided direction for support and development of clinical educators within the context of the curriculum     

An investigation into nurses' understanding of health education and health promotion within a neuro-rehabilitation setting*

This qualitative study was undertaken at two neuro-rehabihtation centres in England, with the aim of exploring the nurses' understanding of health education and health promotion and their role within it, and their perception of illness and wellness related to disability The principle of methodical triangulation was employed using questionnaires, group interviews and content analysis of client care plans Although the nurses had difficulty distinguishing between health promotion and health education, differences did emerge which were supported by the literature The nurses generally identified their role as being one of health promotion However, they tended to equate wellness with physical independence As a result of the study a health promotion model based on the principles of self-empowerment is suggested, which could be used as a framework for rehabilitation nurses and other professionals to enable them to focus on health and wellness rather than illness and disability     

REHABILITATION OF LOWER LIMB AMPUTEES AND SOME IMPLICATIONS FOR SURGICAL MANAGEMENT

Aspects of peri-operative management, amputation level and rehabilitation of the lower limb amputee are reported in the context of a review of a rehabilitation service for amputees which includes an integrated prosthetic service. Two hundred admissions were reviewed and some complex cases described. It is concluded that: a very close liaison between the surgeon and the rehabilitation team (ideally with pre-operative consultation) is in the patient's best interests; any person previously walking (or a potential walker) should be considered for a trial of prosthetic walking; an integrated prosthetic service enhances the efficiency of the rehabilitation service; and that modification of the current Artificial Limb Scheme to allow manufacture of first definitive limbs in prosthetic rehabilitation units would further enhance service to patients.
