Nursing diagnoses in elderly residents of a nursing home: a case in Turkey

There are limited studies on nursing diagnoses of the elderly living in nursing homes worldwide. This study aimed to define the most frequent nursing diagnoses in the elderly residents of a nursing home elder care and rehabilitation center. Seventy-four elderly individuals were included in the study. Data were collected using the “Elderly Individual’s Introduction Form” between April 2007 to August 2007. The content of the form was based on a guide to gerontologic assessment, and Gordon’s Functional Health Patterns. The nursing diagnoses (NANDA-I Taxonomy II) were identified by the 2 researchers separately according to the defining characteristics and the risk factors. The consistency between the nursing diagnoses defined by the 2 researchers was evaluated using Cohen’s kappa (κ). There was an 84.7% agreement about nursing diagnoses defined by the 2 researchers separately. The weighted kappa consistency analyses showed there was an adequate level of consistency (κ = 0.710), and the findings were significant (p < 0.0001). The most frequent diagnoses were ineffective role performance (86.5%), ineffective health maintenance (81.2%), risk for falls (77%), and impaired physical mobility (73%). The diagnosis of ineffective role performance was more frequent in patients with dementia (x² =10.993, df = 1, p = 0.001). There was a very significant relationship between dementia and the diagnosis of impaired verbal communication (x² = 32.718, df = 1, p = 0.0001). The relationship between mobility disorder and self-care deficit was also significant (x² = 19.411, df = 1, p = 0.0001). To improve quality in patient care, nurses should use nursing diagnoses with a systematic assessment and should help the elderly in health promotion or use of the maximum current potential.     

Upper and lower gastrointestinal endoscopical investigation in elderly patients with iron deficiency anaemia

Iron deficiency anaemia is frequently observed in male adults and postmenopausal women due to chronic occult bleeding, usually from the gastrointestinal tract. Practically, as endoscopical investigation of the gastrointestinal system is an invasive procedure, iron replacement treatment was generally started without investigation of the underlying aetiology even in first-line health institutions. This study evaluates the role of endoscopy in the investigation of the aetiology of anaemia in 95 patients (51 males, 44 females), aged 64.9+/-12.5 years (range 50-90 years). All patients having iron deficiency anaemia were investigated by upper gastrointestinal endoscopy and colonoscopy. Upper and lower gastrointestinal pathologies were seen in 10 (10.6%) and 55 (57.8%) patients, respectively. However, no gastrointestinal lesion was found in 30 (31.6%) patients with iron deficiency anaemia. Out of the 95 patients, 16 (16.9%) had erosive gastritis, 15 (15.8%) duodenal ulcer, 8 (8.4%) gastric ulcer, 7 (7.3%) gastric tumours, 7 (7.3%) oesophagitis. 5 (5.4%) colon tumours, 3 (3.2%) haemorrhoids, 2 (2.1%) non-tropical sprue, 1 (1%) colonic polyp, and 1 (1%) colitis. In the majority of elderly patients with iron deficiency anaemia, upper gastrointestinal system disease was found. In 12 (12.7%) patients in the study group, malignancies were detected. In elderly patients with iron deficiency anaemia, the aetiology should be highlighted before giving iron supplementation.     

Urotensin II levels in patients with chronic kidney disease and kidney transplants

Objective.

Urotensin II is a potent vasoactive peptide that has been implicated in the pathophysiology of many diseases. There is no study reporting the role and level of this peptide in recipients of kidney transplant. So we aimed to study the plasma levels of urotensin II in this group of patients.

Methods.

Plasma urotensin II levels were analyzed in 110 subjects, who were divided into three groups: group 1 (35 kidney transplant recipients), group 2 (36 patients with chronic kidney disease), and group 3 (39 healthy controls).

Results.

Analysis of logarithmic transformation of urotensin II, i.e. log (urotensin II × 1000) levels, with a one-way analysis of variance yielded a P value of 0.001. Post-hoc analysis showed significantly higher log (urotensin II × 1000) levels in group 1 than groups 2 and 3 (P = 0.001 and 0.017, respectively). One of the important features of the subjects of this group was that they were taking immunosuppressive drugs because of renal transplantation.

Conclusions.

High urotensin II levels in recipients of kidney transplants could be drug-related (immunosuppressive drugs) and may be of practical importance that may be used to improve the long-term outcome of the patients.     

Monte Carlo simulation of sensitivity and NECR of an entire-body PET scanner

The current positron emission tomography (PET) design is aimed toward establishing an entire-body PET scanner. An entire-body PET scanner is a scanner whose axial field of view (FOV) covers the whole body of a patient, whereas whole-body PET scanner can be of any axial FOV length, but was designed for a whole-body scan. Despite its high production cost, an entire-body depth-of-interaction PET scanner offers many benefits, such as shorter and dynamic PET time acquisition, as well as higher sensitivity and count rate performance. This PET scanner may be cost-effective for clinical PET scanners with high scan throughput. In this work, we evaluated the sensitivity and count rate performance of a 2-m-long PET scanner with conventional data acquisition (DAQ) architecture, using Monte Carlo simulation, and we evaluated two ring diameters (60 and 80 cm) to reduce the scanner cost. From simulation of scanning with a 2-m axial FOV, the sensitivity for a 2-m-long PET scanner of 60 and 80-cm diameter is around 80 and 68 times higher, respectively, than that of the conventional PET scanner. In addition, for the 2-m-long PET scanner with 60-cm diameter, the peak noise equivalent count rate (NECR) was 843 kcps at 125 MBq, whereas the peak for the 80-cm diameter was 989 kcps at 200 MBq. This shows gains of 15.3 and 17.95, respectively, in comparison with that of the conventional PET scanner. The 2-m-long PET scanner with 60-cm ring diameter could not only reduce the number of detectors by 21 %, but also had a 17 % higher sensitivity compared to that with an 80-cm ring diameter. On the other hand, despite the higher sensitivity, the NECR of the 60-cm ring diameter was smaller than that of the 80-cm ring diameter. This results from the single data loss due to dead time, whereas grouping of axially stacked detectors was used in the conventional DAQ architecture. Parallelization of the DAQ architecture is therefore important for the 2-m-long PET scanner to achieve its optimal performance.     

Prevalence of orthorexia among medical students in Erzurum, Turkey

Orthorexia is a new term about eating behavior disorder and consists of pathologic obsession for biologically pure foods, free of herbicides, pesticides, and other artificial substances. It is not an independent diagnostic category, but it has some similarities with other eating disorders. This study was conducted to examine the orthorexia among 878 medical students. Of 878 students, 464 (52.8%) were male and 359 (40.9%) were female. The mean age, height, weight, and body mass index were 21.3 ± 2.1 years, 171.0 ± 8.5 cm, 65.6 ± 12.3 kg, 22.4 ± 2.99, respectively. The rates of the ORTO-11 scores between 0 and 15 was 1.9%; between 16 and 30, 57.5%; and between 31 and higher, 21.1%. There were 17 students with a score of 0 to 15. The mean score for the ORTO-11 test was 27. There were statistically significant differences between age, sex, and smoking habit of the students. In the male students, there was a statistically significantly higher tendency for orthorexia (P = .001), and there was a statistically significant difference between the age groups for tendency for orthorexia (P = .025). In logistic regression analysis, age, sex, Eating Attitude Test-40 (EAT-40), and height affected the ORTO-11 scores.     

IMPACT OF HEPARIN LOCKING FREQUENCY ON PREVENTING TEMPORARY DIALYSIS CATHETER DYSFUNCTION IN HAEMODIALYSIS PATIENTS

A prospective analysis was conducted comparing dysfunction attributable to catheter thrombosis in subjects who received a heparin catheter lock three times a week (n = 15) to those who received a heparin lock six times a week (n = 15) immediately after the insertion of a temporary haemodialysis catheter. Thrombus related catheter removal occurred in two patients in control but no patients in the experiment group. Heparin locking six times a week was found to be effective in prolonging the mean of the first day where difficulty was experienced in aspiration. It also prevented any possible difficulty in catheter flushing. Increased locking frequency prevents any thrombus accumulation within the temporary catheter, while it has limited but significant preventive effect on thrombus accumulated around the catheter.     

Effects of smoking on clinical parameters and the gingival crevicular fluid levels of IL-6 and TNF-alpha in patients with chronic periodontitis

OBJECTIVE: Smoking is an important environmental risk factor for the initiation and progression of periodontal diseases. The aim of this study was to evaluate the effects of smoking on clinical parameters and the gingival crevicular fluid (GCF) contents of the pro-inflammatory cytokines interleukin-6 (IL-6) and tumor necrosis factor-alpha (TNF-alpha) levels in patients with chronic periodontitis. MATERIAL AND METHODS: The study base consisted of 41 patients including 22 volunteer current smokers with an age range of 32-59 (44.41+/-7.88) years and 19 volunteer non-smokers with an age range of 36-59 (46.94+/-6.07) years. The first month after non-surgical periodontal therapy was accepted as the baseline of the study. The clinical parameters including plaque index (PI), gingival index (GI), bleeding on probing (BOP), probing depth (PD), clinical attachment loss (CAL) were recorded and GCF samples were collected for analysis of GCF contents of IL-6 and TNF-alpha levels. At the 3rd and 6th months, all of these procedures were repeated. RESULTS: In smokers, only CAL was significantly higher at the 3rd month compared with non-smokers (p<0.05). GI and BOP were higher in non-smokers than smokers in both periods (p<0.05). PI showed increases from the initial to the 6th month in smokers (p<0.05). Although the differences between two groups with regard to IL-6 and TNF-alpha were not significant (p>0.05), the total amount of TNF-alpha in GCF decreased from the initial to the 6th month in smokers (p<0.05). There were no significant correlations between the mean total amount of IL-6 and TNF-alpha in GCF and clinical parameters in both evaluation periods in smokers (p>0.05). CONCLUSION: The present study demonstrated that cigarette smoking increases the amount of dental plaque over time in smokers and does not influence GCF contents of IL-6 and TNF-alpha.     

Periodontal treatment needs of patients with renal disease receiving haemodialysis

AIM/OBJECTIVE: The aim of this study was to perform periodontal assessment, using the CPITN index, on patients undergoing renal dialysis. METHODS: The periodontal conditions of 342 subjects undergoing renal dialysis from eight renal dialysis centres were examined using CPITN. Subjects were distributed into four age groups, 16-19, 20-34, 35-44 and > or =45 years. The study was conducted during a 6-month period. All clinical examinations were performed by one examiner. RESULTS: There was a significant positive relationship between the CPITN scores and age (r=0.164, p=0.002) and dialysis duration (r = 0.240, p=0.000). There was no statistically significant difference between male and female patients (p>0.05). None of the age groups had healthy sextants. The 35-44 year-age group had a higher number of sextants with deep pockets (0.19) than the other age groups and edentulous sextants were the highest among the oldest age group (1.89). CONCLUSION: A very small portion of the renal dialysis population is affected by severe forms of periodontitis requiring complex periodontal treatment. However, all such patients should be given oral hygiene education as a priority.
