METHODS: Data were retrospectively extracted from all the Chemotherapy Return Forms in 2016, which is a compulsory documentation accompanying each return of parenteral chemotherapy regimen. The following data were extracted: patient's diagnosis, gender, location of treatment (i.e. ward/daycare clinic), start date of chemotherapy regimen, type of cytotoxic drug returned, dose of cytotoxic drug returned, number of cytotoxic drug preparations returned and reason for return as well as whether the returned cytotoxic drug preparations could be re-dispensed. The cost of wastage was calculated based on the cost per mg (or per unit) of the particular returned cytotoxic drug.
RESULTS: One hundred and fifty-nine cases of returned chemotherapy regimen comprising of 231 parenteral cytotoxic drug preparations were analysed. The total cost of returned chemotherapy regimen for 2016 was €3632, with €756 (20.8%) worth of chemotherapy regimens returned due to preventable reasons and €2876 (79.2%) worth of chemotherapy regimens returned due to non-preventable reasons. Approximately 50% of cases returned chemotherapy regimen were due to deterioration of patient's clinical condition and another 24.5% of cases of returned chemotherapy regimen were attributed to adverse drug reactions.
CONCLUSION: Wastage associated to non-preventable reasons such as adverse drug reactions and preventable causes like refusal of patients can be further reduced by using newer healthcare innovations and establishment of written institutional protocols or standard operating procedures as references for in-charge healthcare personnel when cytotoxic drug-related issues occur. Adoption of cost-saving strategies that have been proven by studies could further improve current cost containment strategies.
METHODS: A randomized controlled study was carried out in the neonatal intensive care unit (NICU) of Hospital Universiti Kebangsaan Malaysia over a 12-month period. Fifty-four healthy term infants with severe hyperbilirubinemia were randomized to receive either solely enteral feeds (n = 27) or both enteral and intravenous (n = 27) fluid during phototherapy.
RESULTS: There were no significant differences in the mean birthweight, mean gestational age, ethnic distribution, gender distribution, modes of delivery and types of feeding between the two groups. Similarly, there was no significant difference in the mean indirect serum bilirubin (iSB) level at the time of admission to the NICU between the enteral (359 +/- 69 micromol/L [mean +/- SD]) and intravenous group (372 +/- 59 micromol/L; P = 0.4). The mean rates of decrease in iSB during the first 4 h of phototherapy were also not significantly different between the enteral group (10.4 +/- 4.9 micromol/L per h) and intravenous group (11.2 +/- 7.4 micromol/L per h; P = 0.6). There was no significant difference in the proportion of infants requiring exchange transfusion (P = 0.3) nor in the median duration of hospitalization (P = 0.7) between the two groups. No infant developed vomiting or abdominal distension during the study period.
CONCLUSION: Severely jaundiced healthy term infants had similar rates of decrease in iSB levels during the first 4 h of intensive phototherapy, irrespective of whether they received oral or intravenous fluid supplementation. However, using the oral route avoided the need for intravenous cannulae and their attendant complications.
Methods: Four ampoules of intravenous co-trimoxazole were injected into an infusion bag containing either 480 (1:25 v/v), 380 (1:20 v/v), 280 (1:15 v/v) or 180 (1:10 v/v) mL of glucose 5% solution. Three bags for each dilution (total 12 bags) were prepared and stored at room temperature. An aliquot was withdrawn immediately (at 0 hour) and after 0.5, 1, 2 and 4 hours of storage for high-performance liquid-chromatography (HPLC) analysis, and additional samples were withdrawn every half an hour for microscopic examination. Each sample was analysed for the concentration of trimethoprim and sulfamethoxazole using a stability indicating HPLC method. Samples were assessed for pH, change in colour (visually) and for particle content (microscopically) immediately after preparation and on each time of analysis.
Results: Intravenous co-trimoxazole at 1:25, 1:20, 1:15 and 1:10 v/v retained more than 98% of the initial concentration of trimethoprim and sulfamethoxazole for 4 hours. There was no major change in pH at time zero and at various time points. Microscopically, no particles were detected for at least 4 hours and 2 hours when intravenous co-trimoxazole was diluted at 1:25 or 1:20 and 1:15 v/v, respectively. More than 1200 particles/mL were detected after 2.5 hours of storage when intravenous co-trimoxazole was diluted at 1:15 v/v.
Conclusions: Intravenous co-trimoxazole is stable over a period of 4 hours when diluted with 380 mL of glucose 5% solution (1:20 v/v) and for 2 hours when diluted with 280 mL glucose 5% solution (1:15 v/v).
METHODS: Application of nanotechnology in medicine have perceived a great evolution during past few decades. Nanoemulsion, submicron sized thermodynamically stable distribution of two immiscible liquids, has gained extensive importance as a nanocarrier to improve chemotherapies seeking to overcome the limitations of drug solubilization, improving systemic delivery of the chemotherapeutics to the site of action to achieve a promising inhibitory in tumor growth profile with reduced systemic toxicity.
RESULTS AND CONCLUSION: This review has focused on potential application of nanoemulsion in the translational research and its role in chemotherapy using oral, parenteral and transdermal route to enhance systemic availability of poorly soluble drug. In summary, nanoemulsion is a multifunctional nanocarrier capable of enhancing drug delivery potential of cytotoxic agents, thereby, can improve the outcomes of cancer treatment by increasing the life-span of the patient and quality of life, however, further clinical research and characterization of interactive reactions should need to be explored.
METHODS: Retrospective data on serum calcium and infusion rates was collected from 2011-2015. The relationship between peak calcium efflux (PER) and time was determined using a scatterplot and linear regression. A comparison between regimens was made based on treatment efficacy (hypocalcaemia duration, total infusion amount and time) and calcium excursions (outside target range, peak and trough calcium) using bar charts and an unpaired t-test.
RESULTS: Fifty-one and 34 patients on the original and new regimens respectively were included. Mean PER was lower (2.16 vs 2.56 mmol/h; P = 0.03) and occurred earlier (17.6 vs 23.2 h; P = 0.13) for the new regimen. Both scatterplot and regression showed a large correlation between PER and time (R-square 0.64, SE 1.53, P
