Prophylactic use of chlorpromazine to improve survival of random skin flaps in pigs

On the basis of earlier success in rat studies, chlorpromazine was evaluated as a probable agent for improving survival of random skin flaps in pigs. The aim was to exclude the possibility that the effect of the chlorpromazine is species specific and to find out if it is dose dependent. One hundred and five dorsally-based 12×4 cm flaps were raised unilaterally on the backs of 15 pigs. The animals were divided into three groups using 15 mg/kg chlorpromazine, 7.5 mg/kg chlorpromazine, and a saline-treated control group. Flaps in the control group averaged 40.57±3.17% necrosis, while flaps in the 15 mg/kg and 7.5 mg/kg chlorpromazine-treated groups averaged 31.53±4.77% and 11.47±2.22% necrosis respectively. These results demonstrate dose dependent beneficial affects of chlorpromazine and the survival of random skin flaps in the pig. Although ideal dose levels are still to be determined, flap survival improved with the prophylactic use of chlorpromazine at the lower 7.5 mg/kg dosage.     

Comparison of positive allergy skin tests among asthmatic children from rural and urban areas living within small geographic area.

BACKGROUND: Evidence of increased asthma and allergic response among urban versus rural residents has been reported. OBJECTIVE: To evaluate the prevalence of allergic response among asthmatic children from urban and rural areas living within close proximity. METHODS: In all, 448 asthmatic children from urban (363) and rural (85) areas were studied. The study group consisted of 234 9-year-olds and 214 12-year-olds. A health questionnaire was completed on each child who subsequently underwent allergic skin prick tests (SPTs). RESULTS: There was significantly more positive SPT response to house-dust mite, mold, cat, and cypress among asthmatic children from urban areas compared with children living in rural areas: 58.3% versus 37.6%, 46.1% versus 31.8%, 17.45 versus 5.9%, and 26.2% versus 15.3%, respectively. Positive SPT for indoor allergens were significantly greater among asthmatic urban residents than asthmatic rural residents: 63.3% versus 45.5%, respectively (P < 0.02). Positive SPT response to all the allergens checked was higher among the 12-year-old age group when compared with the 9-year-olds, 34.6% versus 22.7%, respectively (P = 0.05). CONCLUSIONS: Allergic response measured by SPT is significantly more common among asthmatic children from urban areas as opposed to rural, even though both areas are within small distance of one another. Further, asthmatic children living in urban areas demonstrated more allergic response to both indoor and outdoor allergens. The allergic response tends to increase with increased age in both urban and rural asthmatic children.     

A randomized,double-blind placebo-controlled add-on trial to assess the efficacy,safety, and anti-atherogenic effect of spirulina platensis in patients with inadequately controlled type 2 diabetes mellitus

The efficacy of spirulina platensis (S. platensis) as an add-on therapy to metformin and its effect on atherogenic keys in patients with uncontrolled Type 2 Diabetes Mellitus (T2DM) was evaluated. Sixty patients were randomly assigned to S. platensis (2 g/day) or placebo group for three months while continuing metformin as their usual treatment. The efficacy of S. platensis was determined using the pre- and post-intervention HbA1c levels (primary outcome) as well as tracking FBS and lipid profiles levels (TC, LDL-C, TG, and HDL-C) as secondary outcomes at the different treatment time points (0,30,60,90 days). During the three–month intervention period, supplementation with S. platensis resulted in a significant lowering of HbA1c (↓1.43, p < 0.001) and FBS (↓ 24.94 mg/dL, p < 001) levels. Mean TG in the intervention group was found to be significantly lower in the intervention group than in controls (p < 0.001). Total cholesterol (TC) and its fraction, LDL-C, exhibited a fall (↓41.36 mg/dL and ↓38.4 mg/dL, respectively; p < 0.001) coupled with a marginal increase in the level of HDL-C (↑3 mg/dL; p < 0.001). Add-on therapy with S. platensis was superior to metformin regarding long-term glucose regulation and controlling blood glucose levels of subjects with T2DM. Also, as a functional supplement, S. platensis has a beneficial effect on atherogenic keys (TG and HDL-C) with no adverse events.     

A pilot study of home-based genetic testing completion rate in telegenetics cancer clinics in West Virginia Appalachia

Telegenetics has shifted some genetic testing performance to the patient's own home, with the patient collecting his/her own sample. Little is known regarding the rate of test completion of such home-based genetic testing. This study compared the completion rate of home-based genetic tests before and after a reminder system was implemented. In the pre-reminder group, we reviewed medical records for patients who were seen via telegenetics and agreed to complete genetic testing using an at-home test kit. In the reminder group, a prospective analysis of the genetic test completion rate was performed taking a clinical quality improvement approach where three reminders were provided for patients who had not submitted their at-home genetic testing. Our study included 94 patients' records: 46 pre-reminders and 48 reminders. The lab received 24 patient samples (52.2%) in the pre-reminder group. In the reminder group, 30 patients returned their kits (62.5%). Despite a higher percentage of patients completing their test in the reminder group, there was no statistically significant difference between the pre-reminder and reminder groups. The rate of test completion in our pilot test was statistically similar between the two groups, but the reminder group was trending toward a higher percent of completion which may be clinically meaningful.     

Diagnostic and therapeutic advantages of rigid ureteroscopy: retrospective study of 304 cases

Uretroscopy has become a common tool for the diagnosis and management of the upper urinary tract. Between April 1994 and Decembre 1999, 304 ureteroscopy procedures were performed. The most common therapeutic procedure was stone manipulation in 299 cases (distal ureter 259 cases, mid-ureter 23 cases, lumber ureter eight cases and staged in nine cases). Procedure was made by a rigid ureteroscope 8.5 Ch or 11.5 Ch. Dorinia was used in 175 cases (57.5%) with or without fragmentation by ultrasound. Therapeutic ureteroscopy was also used to remove a double-J stent that had migrated into the pelvic ureter in one case and in three cases of ureteral tumor. It was used in one case to confine the extrinsic compression of a ureteral stenosis. Median follow up was 12 months (6-36 months). The overall success rate was 87.6%. Results are comparable in men and women (P = 0.8). Success rate was 90% in single lithiasis and 76.2% in case of numerous stones (P = 0.0094). There was a statistically significant difference in success rate between stones 15 mm or under in size (89% stone-free) and those 15 mm (66% stone-free) or larger. In conclusion, rigid ureteroscopy is a minimally invasive and reliable technique for the management of ureteric calculi and for the diagnosis and treatment of other ureteric lesion.     

Factor Structure of the Urdu Version of the Spence Children's Anxiety Scale in Pakistan

Spence Children's Anxiety Scale (SCAS) is one of the most commonly used self-report questionnaires to measure symptoms of anxiety disorders in adolescents. Despite its common use, studies that examine the psychometric properties of SCAS in Pakistan is lacking. Therefore, the purpose of this study was to examine the psychometric properties of the Urdu translated version of the SCAS among adolescents in Pakistan. A total of 1277 students (708 boys and 569 girls), aged 13 to17 years, who had been recruited from 13 schools in Rawalpindi, Pakistan participated in the study. The mean overall anxiety score was significantly higher in girls than males on all the SCAS subscales except for obsessive compulsive disorder. The internal consistency of the Urdu SCAS was good. Confirmatory factor analyses supported six separate factor structures. Results of the study are discussed with reference to the sociocultural milieu of Pakistan and culture sensitive conceptualization of anxiety and its subtypes.     

Cultivating a culture of research in nursing through a journal club for leaders: A pilot study

Aim

To describe whether an action learning‐inspired journal club for nurse leaders can develop the leaders' self‐perceived competences to support a research culture in clinical nursing practice.

Background

Development of clinical research capacity and nurse leaders with the requisite competences are key factors in evidence‐based health care practice. This study describes how nurse leaders at a large regional hospital took part in a journal club for nurse leaders, with a view to developing their competences to support a nursing research culture in their departments.

Methods

A pilot study using a multimethod approach to evaluate the journal club for nurse leaders. Four nurse leaders participated in the journal club for nurse leaders. Content analysis on the data was performed.

Results

Data revealed that participation in journal club for nurse leaders gave the leaders a feeling of increased competences to support nursing research culture in their departments. They stated that the action learning approach and the competences of the facilitator were key factors in this outcome.

Conclusions

An action learning‐inspired journal club for nurse leaders can be useful and meaningful to nurse leaders in developing leadership competences.

Implications for nursing management

As an approach in journal club for nurse leaders, action learning can develop nurse leaders' competence to support a research culture, and thus ensure evidence‐based nursing is practised.
