Summary OBJECTIVE The extent to which treatment modifies the excess in morbidity and mortality acromegaly remains uncertain. This study investigates determinants of final outcome following therapy for acromegaly. DESIGN A retrospective analysis patients treated at Departments Endocrinology Neurosurgery, Auckland Hospital, New Zealand. PATIENTS One hundred fifty‐one (63 females 88 males) with or gigantism between years 1964 1989. mean duration follow‐up was 12 (median 11 years). MEASUREMENTS...
Summary 1. Soil resource availability and disturbance are widely recognized as key drivers of plant community structure. However, the relative importance different traits in determining species abundance following shifts soil remains little studied, particularly long‐term experiments. 2. We studied trait‐based assembly a 27‐year grassland experiment where 25 were sown into resident vegetation, after which annual manipulations (five levels superphosphate fertilizer; highest level was also...
Abdominal aortic aneurysm (AAA) is a common human disease with high estimated heritability (0.7); however, only small number of associated genetic loci have been reported to date. In contrast, over 100 now reproducibly either blood lipid profile and/or coronary artery (CAD) (both risk factors for AAA) in large-scale meta-analyses. This study employed staged design investigate whether the these two phenotypes are also AAA. Validated CAD and dyslipidaemia underwent screening using Otago AAA...
The serum fructosamine concentration was examined as a new means to monitor metabolic control in non-insulin-dependent diabetes during changes management. Weekly estimations were compared with glycosylated haemoglobin (HbA1c), 24 hour urinary glucose, and fasting plasma glucose concentrations 17 week study entailing withdrawal reinstitution of oral treatment. more sensitive than the other measurements detecting deterioration diabetic after stopping hypoglycaemic drugs. response treatment not...
Abstract Questions Is trait convergence more intense when soil resource availability and disturbance constrain productivity limit above‐ground competition? Do the effects of on functional diversity differ between local metacommunity scales? Location Semi‐arid grasslands in N ew Z ealand (43°59′ S, 170°27′ E). Methods We measured divergence along gradients primary at (i.e. 1 m × m) (8 50 scales, using long‐term (27‐yr) manipulations grazing intensity. compared dispersion metrics to those...
Objective: To determine the prognostic relevance, clinical characteristics, and 30-day outcomes associated with myocardial injury after noncardiac surgery (MINS) in vascular surgical patients. Background: MINS has been independently mortality surgery. The characteristics importance of patients are poorly described. Methods: This was an international prospective cohort study 15,102 45 years or older, whom 502 underwent All had fourth-generation plasma troponin T (TnT) concentrations measured...
We review the theory and application of generalized linear autoregressive moving average observation-driven models for time series counts with explanatory variables describe estimation these using R package glarma. Forecasting, diagnostic graphical methods are also illustrated by several examples.
Abstract The long saphenous vein is frequently used as a graft in both coronary artery and femoro‐distal bypass surgery. histological changes which are seen after implantation into the arterial system have been well documented past, but little attention has focused on appearances of donor prior to grafting. In this study, samples excess that required for examined. none veins did conform described normal. All showed evidence intimal fibrosis contained elastic tissue enmeshed smooth muscle...
Jaundice-Dawson BRITISH that a mannitol diuresis exerts protective effect against anoxia.Mannitol has been suggested as pro- phylactic measure the development of post-operative renal failure in patients at risk-for example, cross-clamping abdominal aorta during grafting (Barry et al., 1961).Moore (1963) also recommends its use similar circumstances and suggests it might prove prophylactic value deeply jaundiced undergoing operation.The results these experiments strongly support this...
Ablation of the p1tmtary gland appears to alter course diabetic retinopathy in some patients.This is purely an empirical form therapy.It developed mostly from observation a patient with advanced who, following pregnancy, hemorrhage, and onset Sheehan's syndrome (or hypopituitarism) , showed marked regression retinopathy.This was made by Poulsen (1953).Shortly thereafter, Luft, Olivecrona, Sjogren, (1955) Stockholm, performed surgical hypophysectomy group patients rather vascular disease...
Summary The frequency of species at successive levels within a vegetation is determined from their intercepts on vertical sampling cylinders. cylinders are visually estimated using rod with attached guide rings. theory and statistical characteristics the method discussed some examples its use given.
Case 4.-For six months this 57-year-old man had been suffering from severe lumbar pain.No abnormality was found on examination.The testes were noted to be normal.Radio- graphs revealed destruction of the second vertebra, but further investigations, including blood and marrow examina- tion, electrophoresis serum proteins, skeletal survey, an intravenous pyelogram, all normal.X-ray therapy given affected vertebra.Two later he complained
The effect of sarcopenia based on the total psoas muscle area (TPMA) CT is inconclusive in patients undergoing abdominal aortic aneurysm (AAA) intervention. aim this prospective cohort study was to evaluate morphometric as a method risk stratification elective AAA intervention.TPMA measured preintervention images endovascular repair (EVAR) or open repair. Mortality assessed relation TPMA using Cox regression analysis, with calculation hazard ratios at 30 days, 1 year and 4 years....
Abstract Background Physical examination is unreliable in the detection of sources reflux varicose veins. Hand-held Doppler (HHD) ultrasonography has been recommended as an accurate adjunct to physical examination. The aim this study was evaluate accuracy HHD imaging comparison with duplex ultrasonography. Methods Eighty-nine legs 61 patients primary veins were examined probe detect at saphenofemoral junction (SFJ), saphenopopliteal (SPJ) and thigh perforators (TPs). Patients then underwent...
Abstract Background The aims of this prospective study were to analyse the health-related quality life (QOL) changes associated with infrainguinal arterial reconstruction for chronic critical limb ischaemia (CLI) and assess impact graft patency salvage. Methods Fifty-five consecutive patients, 28 women 27 men median age 71 (range 41–86) years, undergoing CLI, consented participate in study. QOL was assessed using Short Form 36 (SF36) health survey questionnaire, which completed before at 1,...
