Patient preferences and predicted relative uptake for targeted therapies in metastatic colorectal cancer: a discrete choice experiment

Abstract

Objective

Ras wild-type metastatic colorectal cancers (mCRC) may be treated with anti-vascular endothelial growth factor (VEGF) or anti-epidermal growth factor receptor (EGFR) agents. We aim to estimate patients’ preferences for mCRC treatment and relative importance of cost, efficacy improvement, avoidance of side effects and therapy convenience, and relative uptake between profiles that resemble Bevacizumab (anti-VEGF) and Cetuximab (anti-EGFR), two commonly prescribed mCRC targeted therapies.     

A guide to upwardly mobile spermatozoa

Morphological comparison of sperm in raw ejaculates and swim-ups showed that the swim-up process does not simply increase the proportion of 'normal' sperm. Rather, sperm of specific morphologies have characteristic grades of upward motility.     

Management of hip dislocations in children with arthrogryposis

From a review of 131 children with arthrogryposis, we studied 18 patients with hip dislocations. Fourteen patients (10 unilateral, four bilateral) were treated by open reduction. Mean age at surgery was 9.7 months, and follow-up ranged from 9 to 245 months. Range of motion of patients treated by open reduction following the medial approach was greater than in those treated by anterolateral incision and greater than in bilateral cases treated by closed reduction. Acetabular development was satisfactory following the medial approach and there were no re-dislocations, but one hip developed avascular necrosis.     

Further study on the vascular basis for the reimplantation of the hand amputated through the palm

Summary Based on the anatomic data obtained from earlier studies on the vascular anatomy of the hand, the vascular architecture in the palm of the hand was studied on 60 sides of unembalmed adult upper extremities. Each palm was divided into 64 squares by 8 sagittal and 8 transverse sections. The vascular architecture in these squares and the arterial relations between them were observed and measured by angiography, operative microscopic dissection and computerised three-dimensional reconstruction. According to the pattern of the blood-vessels, the amputated palms can be classified into 4 types. The anatomic basis for the vascular anastomosis in each type is defined. There are three key-areas for the blood-supply of the palm and their significance is discussed. Apart from the 4 types of transversely amputated palms, the repair programe of the blood-vessles in 4 types of common obliquely amputated palms are also discussed.

Etude complémentaire de l'anatomie vasculaire de la main pour la réimplantation des amputations transpalmaires

Résumé Sur la base de données anatomiques obtenues lors de précédents travaux sur l'anatomie vasculaire de la main, l'architecture vasculaire palmaire a été étudiée sur 60 extrémités supérieures de cadavres d'adultes, non embaumés. Chaque paume a été divisée en 64 carrés par 8 sections sagittales et 8 sections transversales. L'architecture vasculaire à l'intérieur des carrés et les relations artérielles entre eux ont été étudiées et mesurées par angiographie, dissection au microscope opérateur et reconstruction computérisée en 3D. Les paumes amputées ont été regroupées en 4 types d'après la distribution des vaisseaux sanguins. Les données anatomiques concernant les anastomoses vasculaires sont précisées. Il existe trois zones clés pour l'irrigation de la paume. Leur importance quant à l'irrigation de la main est exposée. Outre la division des paumes amputées transversalement en 4 types, le programme de réparation de vaisseaux dans les 4 types d'amputations obliques communes de la paume et aussi discuté.

     

Investigation and treatment of female urinary incontinence

There are four main types of urinary incontinence in the female namely stress incontinence, urge incontinence, overflow incontinence due to retention of urine and total incontinence. It is important to differentiate them to institute proper treatment. It is the aim of this paper to present a simple clinical evaluation of an incontinent woman. The different methods of surgical correction of stress incontinence are discussed. The latest trend is the paraurethral suspension of the bladder neck. 39 cases of Grade II stress incontinence were treated by paraurethral suspension of the bladder neck at "A" Unit, Kandang Kerbau Hospital and Dept. of Urology, SGH. 33 cases were cured. 4 improved with occasional stress incontinence, frequency and urgency. Of these, 3 were cured with imipramine. One failed because of a fixed, "lead pipe" rigid urethra from previous multiple operations to the bladder neck.     

Detection of diacetyl (caramel odor) in presumptive identification of the "Streptococcus milleri" group.

The caramel odor associated with the "Streptococcus milleri" group was shown to be attributable to the formation of the metabolite diacetyl. Levels of diacetyl in the 22- to 200-mg/liter range were produced by 68 strains of the "S. milleri" group; apart from one strain of Streptococcus mutans, all 92 other strains of streptococci belonging to 12 species produced < 13 mg of diacetyl per liter. Quantitation of diacetyl levels from cultures of streptococci is suggested as a rapid presumptive test for the "S. milleri" group.
