Prevention of Pulmonary Complications of Pneumoperitoneum in Rats

Background  

Carbon dioxide (CO₂) pneumoperitoneum facilitates the visualization of abdominal organs during laparoscopic surgery. However, the associated increase in intra-abdominal pressure causes oxidative stress, which contributes to tissue injury.     

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.     

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.     

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.     

Psychological effects of tibolone and sequential estrogen-progestogen therapy in perimenopausal women.

OBJECTIVE: To investigate changes in psychological symptoms before and after continuous tibolone treatment and sequential estrogen-progestogen therapy in perimenopausal women. METHODS: In this prospective, randomized, controlled study, perimenopausal women were randomly allocated to treatment with either tibolone 2.5 mg/day for 28 days (n = 28), or 0.625 mg conjugated equine estrogens (CEE) for 25 days plus 5 mg medroxyprogesterone acetate (MPA) daily on days 16-25 (n = 33). The differences in Beck's depression scores and serum lipid profiles before and after 1 year of treatment with both regimens were compared. RESULTS: Both groups were similar with respect to demographic characteristics. The differences in Beck's depression scores before and after treatment were statistically significant in the tibolone group (21.3 vs 17.1, p = 0.038) and also in the group receiving standard sequential estrogen-progestogen treatment (15.7 vs. 13.0, p = 0.040). In the sequential estrogen-progesterone group, a statistically significant increase was measured in high-density lipoprotein (HDL)-cholesterol levels after treatment (49.1 vs. 56.8 mg/dl, p = 0.023). CONCLUSION: Tibolone is as effective as sequential estrogen-progesterone therapy in alleviating the psychological symptoms of the perimenopause. In addition, CEE + MPA induces favorable changes in HDL-cholesterol.
