OBJECTIVES: To assess the optimal mode of delivery in women with, or carriers of, bleeding disorders.
SEARCH METHODS: We searched the Cochrane Cystic Fibrosis and Genetic Disorders Coagulopathies Trials Register, compiled from electronic database searches and handsearching of journals and conference abstract books. We also searched the Cochrane Pregnancy and Childbirth Group's Trials Register as well as trials registries and the reference lists of relevant articles and reviews.Date of last search of the Group's Trials Registers: 16 February 2017.
SELECTION CRITERIA: Randomised controlled trials and all types of controlled clinical trials investigating the optimal mode of delivery in women with, or carriers of, any type of bleeding disorder during pregnancy were eligible for the review.
DATA COLLECTION AND ANALYSIS: No trials matching the selection criteria were eligible for inclusion MAIN RESULTS: No results from randomised controlled trials were found.
AUTHORS' CONCLUSIONS: The review did not identify any randomised controlled trials investigating the safest mode of delivery and associated maternal and foetal complications during delivery in women with, or carriers of, a bleeding disorder. In the absence of high quality evidence, clinicians need to use their clinical judgement and lower level evidence (e.g. from observational trials, case studies) to decide upon the optimal mode of delivery to ensure the safety of both mother and foetus.Given the ethical considerations, the rarity of the disorders and the low incidence of both maternal and foetal complications, future randomised controlled trials to find the optimal mode of delivery in this population are unlikely to be carried out. Other high quality controlled studies (such as risk allocation designs, sequential design, and parallel cohort design) are needed to investigate the risks and benefits of natural vaginal and caesarean section in this population or extrapolation from other clinical conditions that incur a haemorrhagic risk to the baby, such as platelet alloimmunisation.
METHODS: Thirty consented adult patients who underwent craniotomy were randomly allocated into two groups of 15 patients each. The non-balanced group received 0.9% normal saline while the balanced group received Sterofundin®ISO as the intraoperative fluid for maintenance. Biochemical indices for acid-base balance and serum electrolytes were analyzed periodically.
RESULTS: In the non-balanced group, significant changes were noted in the pH, base excess and bicarbonate values over time compared to its respective baseline values (P<0.01). Four patients (27.7%) also developed a pH<7.35 and 5 patients (33.3%) developed marked acidosis with base excess
METHODS: This was a retrospective cohort study of all patients treated between January 2005 and December 2010.
RESULTS: We included 163 patients with an age range of 6-59 years (median = 19). The median follow-up was 47 months (range 36-84). The overall survival in patients who completed chemotherapy and surgery (n = 117) was 72% at 2 years and 44% at 5 years. Histologically, 99 (85%) had osteoblastic, 6 (5%) had chondroblastic and 3 (2.5%) had telangiectatic osteosarcoma. Limb salvage surgery was performed in 80 (49%) and 41 (25%) underwent amputation. However, 46 patients (28%) underwent no surgical intervention and incomplete chemotherapy. In total, 38/79 patients had a good chemotherapy response. There was a significantly better survival rate for limb salvage versus amputation. Independent prognostic factors for survival are compliance to treatment and presence of lung metastasis.
CONCLUSION: The overall survival of osteosarcoma patients was influenced by the presence of pulmonary metastases and compliance to treatment. Histological subtype, different chemotherapy regimens and histological necrosis after chemotherapy did not significantly influence survival. The patients who did not complete treatment had significantly poorer survival.
AIMS AND OBJECTIVES: This study assessed nurses' sedation scoring and management abilities as primary outcomes following educational interventions. Nurses' perceived self-confidence and barriers to effective sedation management were assessed as secondary outcomes.
DESIGN: A post-test-only quasi-experimental design was used. Data were collected at 3 and 9 months post-intervention.
METHODS: A total of 66 nurses from a 14-bed intensive care unit of a Malaysian teaching hospital participated. The educational interventions included theoretical sessions, hands-on sedation assessment practice using the Richmond Agitation Sedation Scale, and a brief sedation assessment tool. Nurses' sedation scoring and management abilities and perceived self-confidence level were assessed at both time points using self-administered questionnaires with case scenarios. Sedation assessment and management barriers were assessed once at 9 months post-intervention.
RESULTS: Median scores for overall accurate sedation scoring (9 months: 4·00; 3 months: 2·00, p = 0·0001) and overall sedation management (9 months: 14·0; 3 months: 7·0, p = 0·0001) were significantly higher at 9 months compared to 3 months post-intervention. There were no significant differences in the perceived self-confidence level for rating sedation level. Overall perceived barrier scores were low (M = 27·78, SD = 6·26, possible range = 11·0-55·0). Patient conditions (M = 3·68, SD = 1·13) and nurses' workload (M = 3·54, SD = 0·95) were the greatest barriers to effective sedation assessment and management. Demographic variables did not affect sedation scoring or management abilities.
CONCLUSIONS: Positive changes in nurses' sedation assessment and management abilities were observed, indicating that adequate hands-on clinical practice following educational interventions can improve nurses' knowledge and skills.
RELEVANCE TO CLINICAL PRACTICE: Educational initiatives are necessary to improve ICU practice, particularly in ICUs with inexperienced nurses.
METHOD: A qualitative study was conducted at the 3 community palliative care provider organizations in greater Kuala Lumpur from August to October 2014. Data were collected with semistructured interviews with 16 nurses who have provided care to children and was analyzed using thematic analysis. Two categories were identified: (1) challenges nurses faced and (2) coping strategies. The themes identified from the categories are (1) communication challenges, (2) inadequate training and knowledge, (3) personal suffering, (4) challenges of the system, (5) intrapersonal coping skills, (6) interpersonal coping strategies, and (7) systemic supports.
CONCLUSIONS: These results reinforces the need for integration of pediatric palliative care teaching and communication skills training into all undergraduate health care programs. Provider organizational support to meet the specific needs of the nurses in the community can help retain them in their role. It will also be important to develop standards for current and new palliative care services to ensure delivery of quality pediatric palliative care.
METHODS: Polyvinylpyrrolidone-capped AgNPs were synthesized by ultrasound-assisted chemical reduction. Characterization of the AgNPs involved UV-visible spectroscopy, Fourier transform infrared spectroscopy, X-ray diffraction, transmission electron microscopy, and energy dispersive X-ray spectroscopy. Citrobacter sp. A1 and Enterococcus sp. C1 were exposed to varying concentrations of AgNPs, and cell viability was determined. Scanning electron microscopy was performed to evaluate the morphological alteration of both species upon exposure to AgNPs at 1000 mg/L.
RESULTS: The synthesized AgNPs were spherical in shape, with an average particle size of 15 nm. The AgNPs had different but prominent effects on either Citrobacter sp. A1 or Enterococcus sp. C1. At an AgNP concentration of 1000 mg/L, Citrobacter sp. A1 retained viability for 6 hours, while Enterococcus sp. C1 retained viability only for 3 hours. Citrobacter sp. A1 appeared to be more resistant to AgNPs than Enterococcus sp. C1. The cell wall of both strains was found to be morphologically altered at that concentration.
CONCLUSION: Minute and spherical AgNPs significantly affected the viability of the two bacterial strains selected from the environment. Enterococcus sp. C1 was more vulnerable to AgNPs, probably due to its cell wall architecture and the absence of silver resistance-related genes.
