Automated determination of clomipramine and its major metabolites in human and rat serum by high-performance liquid chromatography with on-line colum…
1998
A fully automated method including column-switching and isocratic high-performance liquid chromatography (HPLC) was developed for simultaneous determination of the tricyclic antidepressant clomipramine and its metabolites demethylclomipramine, 2-, 8-, and 10-hydroxyclomipramine, 2-, and 8-hydroxydemethylclomipramine and didemethylclomipramine in serum. After serum injection into the HPLC system and on-line sample clean-up on a clean-up column (Hypersil CN; 10 x 4.6 mm) by an eluent consisting of 35% acetonitrile and 65% deionized water, the chromatographic separation was performed on an analytical column (LiChrospher CN; 250 x 4.6 mm I.D.) by an eluent consisting of 38% acetonitrile and 62%…
Effect of active compression–decompression resuscitation (ACD-CPR) on survival: a combined analysis using individual patient data
1999
Active compression decompression resuscitation (ACD-CPR) has been developed as an alternative to standard cardiopulmonary resuscitation (S-CPR). To determine the effect of ACD-CPR on survival and neurologic outcome in patients with out-of-hospital cardiac arrest, this combined analysis involved individual patient data from 2866 patients from seven separate randomized prospective prehospital studies who had received ACD-CPR or S-CPR after out-of-hospital cardiac arrest in seven international sites. Significant improvement in 1-h survival (odds ratio (OR) = 0.83; confidence interval (CI): 0.695-0.99; P0.05) was found with ACD-CPR (n = 1410) versus S-CPR (n = 1456). The odds ratio for hospital…
Children from broken homes: visits to the school nurse.
1980
Children from broken homes, especially females, have an increased tendency to visit the school nurse. Complaints are often ill-defined, possibly psychosomatic. These children may require additional medical and emotional support from the school nurse. The effect the broken home may have upon a student has important implications for the physical and emotional health of today's youth. An awareness of this finding can provide school nursing personnel valuable insight in the assessment of students who visit the school nurse.
Patient-centred access to health care: a framework analysis of the care interface for frail older adults
2018
Abstract Background The objective of this study was to explore the issues surrounding access to health and social care services for frail older adults with Polish stakeholders, including healthy and frail/pre-frail older adults, health care providers, social care providers, and caregivers, in order to determine their views and perspectives on the current system and to present suggestions for the future development of a more accessible and person-centred health and social care system. Methods Focus groups were used to gather qualitative data from stakeholders. Data were analysed using framework analysis according to five dimensions of accessibility to care: approachability, acceptability, av…
A model of stepwise isovolaemic blood exchange in anaesthetised, spontaneously breathing rats to evaluate the oxygen transport efficiency of artifici…
2000
Our research pursues the production of hypo-oncotic artificial oxygen carriers, based on artificial covalently cross-linked hyperpolymeric mammalian haemoglobins. To evaluate their in vivo efficiency in oxygen delivery to the tissue we developed a small animal model of stepwise isovolaemic blood exchange in anaesthetised, spontaneously breathing rats. With the aid of a two-way respiratory micro valve for small animals the overall oxygen uptake by the tissue of the animal can be determined. Measurements of oxygen contents in arterial and mixed venous blood and of some further blood parameters together with known oxygen-binding characteristics of artificial and native oxygen carriers, permits…
Test-retest reliability and construct validity of the ENERGY-parent questionnaire on parenting practices, energy balance-related behaviours and their…
2012
Published version from the journal: BMC Research Notes. Also available from BMC: http://dx.doi.org/10.1186/1756-0500-5-434 Open Access Background: Insight in parental energy balance-related behaviours, their determinants and parenting practices are important to inform childhood obesity prevention. Therefore, reliable and valid tools to measure these variables in large-scale population research are needed. The objective of the current study was to examine the test-retest reliability and construct validity of the parent questionnaire used in the ENERGY-project, assessing parental energy balance-related behaviours, their determinants, and parenting practices among parents of 10–12 year old chi…
Rat liver preservation by hypothermic oscillating liver perfusion compared to simple cold storage.
1998
Rat livers were preserved hypothermically for 10 or 24 h in vitro as if for transplantation. Two methods of preservation were compared using physiological and biochemical parameters: simple storage and oscillating perfusion. By measuring the nucleotides after preservation the calculated energy charge was significantly higher after 10 and 24 h of oscillating perfusion compared to the simple storage group. In addition, a significant energy charge loading was demonstrated by 10 h oscillating perfusion compared to the initial value prior to perfusion. The oscillating, computer-controlled perfusion permits continuous monitoring of perfusate temperature, O2 consumption, pCO2, portal vein pressure…
Development and validation of a radioimmunoassay for serum melatonin.
1989
A radioimmunoassay using N-[3-(4-hydroxy-3-[4-hydroxy-3- [125I]iodophenylpropionyl)]-5-methoxytryptamine as tracer for determination of melatonin in the serum of different species is described. Melatonin antisera were raised in rabbits by immunization with a bovine serum albumin conjugate of N-[3-(2-aminoethyl)-5-methoxy indole] hemisuccinamide. A single high affinity, specific antiserum was obtained. In contrast to previous studies, the tracer was synthesised in one step in the absence of water, giving an excellent yield of highly pure product. No chromatographic purification step was needed. Polyethylene glycol in combination with goat antirabbit immunoglobulins was used to separate bound…
Efficacy of a blended low-intensity internet-delivered psychological programme in patients with multimorbidity in primary care: study protocol for a …
2019
BackgroundThe World Health Organization (WHO) has included comorbidity between depression and a chronic disease among the 10 leading global health priorities. Although there is a high prevalence of multimorbidity, health care systems are mainly designed for the management of individual diseases. Given the difficulty in delivering face-to-face psychological treatments, alternative models of treatment delivery have been proposed, emphasizing the role of technologies such as the Internet. The aim of this study is to assess the efficacy in Primary Care (PC) of a blended low-intensity psychological intervention applied using information and communication technologies (ICTs) for the treatment of …
Noninvasive blood pressure monitoring evaluation of verapamil slow-release 240-mg antihypertensive effectiveness
1989
The aim of our study was to evaluate the antihypertensive effectiveness of verapamil slow-release (SR), administered once a day. We studied 11 patients, 7 male and 4 female, with an average age of 53.6 +/- 12.86 years, who had essential hypertension. After a drug washout period of at least 15 days, placebo was administered (one tablet per day), and then patients received verapamil SR 240 mg/day at 8:00 a.m. for at least 2 weeks. At the end of the washout, placebo, and active drug treatment periods we performed ambulatory intermittent blood pressure monitoring for 24 h using a Squibb Spacelabs pressurometer. After verapamil treatment, in comparison to placebo, a significant reduction of syst…
