Patients’ experiences of dialysis services: are national health strategy targets being met?

Background The National Health Strategy envisages a health system incorporating patient views; and providing accessible, consultant-led dialysis services with patient choice of dialysis modality, in all regions. Aims To describe patients’ experiences of renal services against National Health Strategy objectives. Methods Telephone interviews with 192 dialysis patients from three hospitals in the Eastern region. Results One-quarter of participants (16% of haemodialysis [HD] and 46% of peritoneal dialysis patients) lived outside the Eastern region, and travelled there because dialysis was not available locally. Two-thirds (65%) had a choice of dialysis modality. High satisfaction with interpersonal care was observed (83–98% satisfaction). Dissatisfaction with physical environment included parking (39–56%), waiting areas (62–69%), HD unit space (74%). Regarding support services, dietary services were satisfactory (92–95%), with lower satisfaction ratings for social and financial support services (62%). Conclusions Structural and management issues must be addressed to advance a quality agenda for renal care in Ireland.

Argas reflexus (Fabricius, 1794) as a cause of acarosis in people

The studies were carried out between 1997-1999 within the administrative district of Toruń. Forty sports pigeon breeders together with their pigeonswere understudy annually. The collected material allowed noticing the following issues: in 1997 and 1998 the Argas reflexus (Fabricius, 1794) was present in dovecotes (individuals) and t he breeds' owners were pricked. In 1998 numerous specimens of the A. reflexus were obtained from the material from the sanitary-epidemiological station. The specimens were collected from the bodies of the people, family members and from their flat located on the highest third floor of the old house. In the mite-infected dovecotes and in the old houserooms, the following steps were suggested: mechanical cleansing, whitewashing, disinfecting, and triple disinsecting, with fourteen-day-long intervals. The people with the symptoms of acariosis were subjected to treatment with calcium, anti-allergic, and anti-fever mixtures, and, in some cases, cortisone ointments were applied. In spite of a considerable growth in the symptoms, the used methods turned out to be successful in all the studied cases.

The expression of type III hyperlipoproteinemia: involvement of lipolysis genes

Type III hyperlipoproteinemia (HLP) is mainly found in homozygous apolipoprotein (APO) E2 (R158C) carriers. Genetic factors contributing to the expression of type III HLP were investigated in 113 hyper- and 52 normolipidemic E2/2 subjects, by testing for polymorphisms in APOC3, APOA5, HL (hepatic lipase) and LPL (lipoprotein lipase) genes. In addition, 188 normolipidemic Dutch control panels (NDCP) and 141 hypertriglyceridemic (HTG) patients were genotyped as well. No associations were found for four HL gene polymorphisms and two LPL gene polymorphisms and type III HLP. The frequency of the rare allele of APOC3 3238 G>C and APOA5 −1131 T>C (in linkage disequilibrium) was significantly higher in type III HLP patients when compared with normolipidemic E2/2 subjects, 15.6 vs 6.9% and 15.1 vs 5.8%, respectively, (P<0.05). Furthermore, the frequencies of the APOA5 c.56 G>C polymorphism and LPL c.27 G>A mutation were higher in type III HLP patients, though not significant. Some 58% of the type III HLP patients carried either the APOA5 −1131 T>C, c.56 G>C and/or LPL c.27 G>A mutation as compared to 27% of the normolipidemic APOE2/2 subjects (odds ratio 3.7, 95% confidence interval=1.8–7.5, P<0.0001). The HTG patients showed similar allele frequencies of the APOA5, APOC3 and LPL polymorphisms, whereas the NDCP showed similar allele frequencies as the normolipidemic APOE2/2. Patients with the APOC3 3238 G>C/APOA5 −1131 T>C polymorphism showed a more severe hyperlipidemia than patients without this polymorphism. Polymorphisms in lipolysis genes associate with the expression and severity of type III HLP in APOE2/2.     

Effect of known history of heart disease on survival outcomes after out‐of‐hospital cardiac arrests

Objective

We aimed to investigate the effect of known heart disease on post‐out‐of‐hospital cardiac arrest (OHCA) survival outcomes, and its association with factors influencing survival.

Methods

This was an observational, retrospective study involving an OHCA database from seven Asian countries in 2009–2012. Heart disease was defined as a documented diagnosis of coronary artery disease or congenital heart disease. Patients with non‐traumatic arrests for whom resuscitation was attempted and with known medical histories were included. Differences in demographics, arrest characteristics and survival between patients with and without known heart disease were analysed. Multivariate logistic regression was performed to identify factors influencing survival to discharge.

Results

Of 19 044 eligible patients, 5687 had known heart disease. They were older (77 vs 72 years) and had more comorbidities like diabetes (40.9 vs 21.8%), hypertension (60.6 vs 36.0%) and previous stroke (15.2 vs 10.1%). However, they were not more likely to receive bystander cardiopulmonary resuscitation (P = 0.205) or automated external defibrillation (P = 0.980). On univariate analysis, known heart disease was associated with increased survival (unadjusted odds ratio 1.16, 95% confidence interval 1.03–1.30). However, on multivariate analysis, heart disease predicted poorer survival (adjusted odds ratio 0.76, 95% confidence interval 0.58–1.00). Other factors influencing survival corresponded with previous reports.

Conclusions

Known heart disease independently predicted poorer post‐OHCA survival. This study may provide information to guide future prospective studies specifically looking at family education for patients with heart disease and the effect on OHCA outcomes.     

The Effect of Body Weight and Body Surface Area Correction on the Distribution of the ACT Response to Bolus Doses of Heparin for PTCA

Considerable controversy exists as to the appropriate dosing of heparin for PTCA. We retrospectively reviewed records of 335 patients undergoing PTCA to determine: 1) the effects of correcting for weight and body surface area (BSA) on the heparin dose-response distribution; and 2) the average dose of heparin (standard, weight-based, and BSA-based) required to achieve an activated clotting time (ACT) of 300 seconds. For each patient, height, weight, BSA, baseline ACT (HemoTec), bolus heparin dose, and post-heparin ACT were recorded and the heparin response calculated. There were no significant differences in the distributions of standard (SD =.017 +/- 006 sec/U, 34% of mean), weight-based (SD = 1.41 +/- 0.46 sec/U/kg, 33% of mean), and BSA-based (SD = 0.033 +/- 0.011 sec/U/m2, 32% of mean) heparin response. There were slight, but significant correlations between heparin response and weight (r = 0.37) and heparin response and BSA (r = 0.36). The estimated doses of heparin to achieve a HemoTec ACT of 300 seconds were 10,650 +/- 1270 U, 130 +/- 15 U/kg, and 5390 +/- 640 U/m2. CONCLUSIONS: There are slight but significant correlations between heparin response and both weight and BSA. The distributions of weight- and BSA-corrected heparin response are similar to that of standard heparin dosing. Thus, weight adjusted heparin dosing would not appear to be likely to provide a more reliable ACT response to bolus doses of heparin.
