Comparison of diclofenac with tramadol, tizanidine or placebo in the treatment of acute low back pain and sciatica: multi-center randomized controlled trial.

BACKGROUND: Low back pain (LBP) is a leading cause of disability worldwide and has posed numerous health and socioeconomic challenges. This study compared whether nonsteroidal anti-inflammatory drugs (NSAIDs) in combination with tramadol, tizanidine or placebo would be the best treatment regime to improve the Roland Morris Disability Questionnaire (RMDQ) scores at 1 week. METHODS: This was a multi-center, double-blind, randomized, and placebo-controlled trial including adult patients with acute LBP and sciatica in three emergency departments in Hong Kong. Patients were randomized to the receive tramadol 50 mg, tizanidine 2 mg, or placebo every 6 hours for 2 weeks in a 1:1:1 ratio. The RMDQ and other secondary outcomes were measured at baseline, Day 2, 7, 14, 21, and 28. Data were analyzed on an intention to treat basis. Crude and adjusted mean differences in the changes of RMDQ and NRS scores from baseline to Day 7 between tizanidine/tramadol and placebo were determined with 95% confidence intervals. RESULTS: Two hundred and ninety-one patients were analyzed with the mean age of 47.4 years and 57.7% were male. The primary outcome of mean difference in RMDQs on Day 7 (compared with baseline) was non-significant for tizanidine compared with placebo (adjusted mean difference - 0.56, 95% CI -2.48 to 1.37) and tramadol compared with placebo (adjusted mean difference - 0.85, 95% CI -2.80 to 1.10). Only 23.7% were fully compliant to the treatment allocated. Complier Average Causal Effect analysis also showed no difference in the primary outcome for the tizanidine and tramadol versus placebo. CONCLUSION: Among patients with acute LBP and sciatica presenting to the ED, adding tramadol or tizanidine to diclofenac did not improve functional recovery.

Filling the Gaps in the Pharmacy Workforce in Post-Conflict Areas: Experience from Four Countries in Sub-Saharan Africa.

BACKGROUND: While the pharmacy workforce is the third largest professional healthcare group worldwide, the pharmacy workforce landscape remains unclear in post-conflict areas in sub-Saharan Africa. METHOD: Key informants were selected for semi-structured interviews due to their role in providing pharmacy services in the selected country: the Central African Republic (CAR), the Democratic Republic of Congo (DRC), Ethiopia, and South Sudan. Transcripts from the interviews were anonymized, coded, and analyzed. RESULTS: Nine participants were recruited (CAR: 2; DRC: 2; Ethiopia: 2; South Sudan: 3), and all except two were pharmacists. Conflict-specific challenges in pharmacy service delivery were identified as the following: unpredictable health needs and/or mismatched pharmaceutical supply, transport difficulties due to insecure roads, and shortage of pharmacy workforce due to brain drain or interrupted schooling. Barriers to health workforce retention and growth were identified to be brain drain as a result of suboptimal living and working conditions or remuneration, the perception of an unsafe work environment, and a career pathway or commitment duration that does not fit the diaspora or expatriate staff. CONCLUSION: To tackle the barriers of pharmacy health workforce retention and growth, policy solutions will be required and efforts that can bring about long-term improvement should be prioritized. This is essential to achieve universal health coverage and the targets of the sustainable development goals for conflict affected areas, as well as to "leave no one behind".

Assessment of English language performance scores and academic performance in an English-based curriculum for pharmacy students with English as a second language.

BACKGROUND: The primary objective was to determine if there is a relationship between English language performance and graduating grade point average (GPA) in pharmacy students with English as a second language (ESL). METHODS: Students graduating from a four-year pharmacy program in 2016-2018 were invited to participate in the study. We compared pharmacy students' pre-admission ESL scores to their cumulative GPA at graduation in each of the three graduating cohorts and also determined if these results held true for both genders. Correlation of GPA to individual mathematics, chemistry, and Chinese language scores were used as points of reference to compare the degree of correlation. RESULTS: There were 148 students screened for the study with 31 students not meeting the inclusion criteria and four students declining to participate. Statistical analyses show an overall weak correlation. There was a statistically significant stronger correlation between pre-admission ESL scores and cumulative graduating GPA (r = 0.273) as compared to the correlation of GPA with mathematics (r = 0.187), chemistry (r = 0.181), or Chinese language scores (r = 0.059). The results did not change when the study population was separated by gender as English score still had the strongest correlation as compared to the other subjects. CONCLUSION: This study provides evidence that English language scores correlate more strongly with academic performance than mathematics, chemistry, or Chinese language scores in ESL pharmacy students. Also, this English language correlation is stronger for females than males.

Retrospective evaluation of resuscitation medication utilization in hospitalized adult patients with cardiac arrest.

BACKGROUND: Early medication administration in cardiac arrest improves outcomes. The primary objective was to evaluate the association between epinephrine administration in in-hospital cardiac arrest (IHCA) patients with non-shockable rhythm and the patient outcomes. The secondary objective was to assess the compliance of epinephrine and amiodarone administration in accordance with the advanced cardiovascular life support (ACLS) guideline. METHODS: IHCA patients aged 18 years or above were identified from the resuscitation registry of 2016 of two public hospitals and categorized according to their initial rhythms. For patients with non-shockable rhythms, the associations between IHCA outcomes, return of spontaneous circulation (ROSC), and survival to discharge, and the time of epinephrine administration were analyzed by logistic regression. The compliance rate of epinephrine and amiodarone administration during resuscitation to ACLS guideline were reported. RESULTS: Among 349 patients with non-shockable rhythm, the median time to epinephrine administration was 3 min (interquartile range, 1-6 min). Early epinephrine administration (<5 min), compared with late epinephrine administration (>5 min), was significantly associated with the rate of ROSC (49.2% vs 34.9%; adjusted odds ratio, 1.630; 95% confidence interval 1.008-2.635, p = 0.046). The time to epinephrine administration (as continuous interval) was significantly associated with the rate of ROSC (p = 0.002) and survival to discharge (p = 0.029). In addition, the compliance rate of epinephrine and amiodarone administration during resuscitation were 83.6% and 33.3%, respectively. CONCLUSION: Our study found that time of epinephrine administration was significantly associated with better results in ROSC and survival to discharge in IHCA patients with non-shockable rhythm. When we divided the IHCA patients with non-shockable rhythms into early and late administration group, early epinephrine administration was associated with significantly improved ROSC, but not survival to discharge after adjusting with potential confounding factors.

Risk factors for aquiring multidrug-resistant organisms in urinary tract infections: A systematic literature review.

BACKGROUND: This is the first review to analyze literature identifying risk factors for a multidrug-resistant urinary tract infection (MDR UTI). Risk factors for other infections involving multidrug-resistant organisms have been evaluated in other reviews, but they do not assess urinary tract infections. The purpose of this study is to collect currently published data to determine the most commonly and consistently identified risk factors for UTIs. MATERIAL AND METHODS: For this study, 3 independent researchers searched PubMed, Embase, and Cochrane database from 1966 to February 2016 for articles identifying risk factors for MDR UTI. RESULTS: A total of 25 studies including 31,284 patients with positive cultures provide evidence for 12 possible risk factors for MDR UTI . The most commonly identified risk factor was previous antibiotic usage as evidenced in 16 of the 20 studies that evaluated this possible risk factor. The time range utilized to define previous antibiotic usage ranged from 2 days to 365 days. Other risk factors with the strongest supporting data were urinary catheterization, previous hospitalization, and nursing home residence. CONCLUSION: We identified 12 different possible risk factors for a MDR UTI, however several risk factors have minimal or conflicting evidence. The definitions of the risk factors varied widely among the studies, and should be standardized for future studies.

Pharmacist Clinical Interventions and Discharge Counseling in Medical Rehabilitation Wards in a Local Hospital: A Prospective Trial.

Patients undergoing rehabilitation experience numerous changes in medication regimens during care transitions, exposing these patients to an increased risk of drug-related problems (DRPs). A prospective, non-randomized, quasi-experimental study was conducted in medical rehabilitation wards to evaluate the impact of pharmacist-delivered interventions and counseling on 30-day unplanned health care utilization and medication adherence for selected rehabilitation patients. A pharmacist provided medication reconciliation and counseling before discharge. Phone follow-up was completed 30 days after discharge to assess for unplanned health care utilization rate and medication adherence. A total of 85 patients (n = 43 in prospective intervention group and n = 42 in historical usual care group) were included. Among the intervention group, 23 DRPs were identified in 14 (32.6%) patients, resulting in 51 interventions. The intervention group had a significantly lower unplanned health care utilization rate than the usual care group (25.6% vs. 47.6%, p = 0.035). The risk of unplanned health care utilization was reduced by over 60% (Odds ratio (OR) = 0.378; 95% CI = 0.15-0.94). Patients reporting medium to high medication adherence increased from 23.6% to 88.4% 30 days after counseling (p < 0.05). Pharmacist medication reconciliation and discharge counseling reduced unplanned health care utilization 30 days after discharge and improved medication adherence.

Evaluation of Drug-Disease Interactions and Their Association with Unplanned Hospital Readmission Utilizing STOPP Version 2 Criteria.

Early hospital readmission is a common problem among geriatric patients, as they are more susceptible to adverse drug events, which are associated with increased hospital admission. The objective is to examine the association between exposure to potentially inappropriate medications under selected STOPP version 2 criteria related to drug-disease interactions and unplanned early hospitalization within 28 days of index admission in elderly patients prescribed a potentially inappropriate medication. This retrospective single-center study reviewed patients 75 years of age or older that were discharged with 5 or more medications, including at least one selected medication listed in the STOPP version 2 criteria relating to drug-disease interactions. 182 patients, with a mean age of 83.5 years, were included in the study, with anticholinergics being the most common potentially inappropriate medications (22.4%). Potentially inappropriate medications (57.1% vs. 17.1%, p < 0.001), gout (31% vs. 11.5%, p = 0.003), and gastrointestinal disease (11.9% vs. 2.5%, p = 0.026) were shown to increase risk of 28-day readmission, whereas no other factors assessed correlated with readmission. A rapid evaluation of elderly patient discharge medications and concomitant disease states with the aid of the STOPP version 2 criteria could potentially reduce hospital readmissions or emergency department visits.

Antithymocyte globulin dosing effects on biopsy-proven acute rejection and infection risk.

BACKGROUND: Antithymocyte globulin (rATG) is a polyclonal antibody commonly used as induction therapy in kidney transplantation to reduce risk of allograft rejection. Currently there is no consensus on the optimal dosing. rATG is not FDA approved for induction therapy, so no dosing recommendations are provided by the manufacturer. Current kidney transplant guidelines do not provide dosing recommendations. The objective of this study was to evaluate effects of different cumulative doses of rATG on rejections and infection rates. MATERIAL AND METHODS: This was a retrospective, single-center chart review that included 142 renal transplant patients from January 2007 to October 2012 who received either 3 or 5 doses of rATG. RESULTS: The primary outcome of biopsy-proven acute rejection (BPAR) was not significantly different between the 3-dose and 5-dose groups, (6.1% versus 7.4%, p=NS). No significant difference was seen between the 3-dose and 5-dose groups in regards to bacterial infections (33.9% versus 40.7%, p>0.05) or BK viremia (24.3% versus 18.5%, p>0.05). However, in regards to CMV viremia there was a significantly higher incidence in the 5-dose group (37% versus 15.7%, p=0.47). CONCLUSIONS: Five doses of rATG versus 3 doses did not provide any additional benefit in preventing BPAR.

Factors affecting access to head and neck cancer care after a natural disaster: a post-Hurricane Katrina survey.

BACKGROUND: Our aim was to survey the factors affecting access to cancer care in patients with head and neck cancer after Hurricane Katrina. METHODS: In this cross-sectional survey, 207 patients with head and neck cancer were identified post-Hurricane Katrina, but only 83 patients completed the questionnaires and were analyzed. Clinical, demographic, and socioeconomic data were recorded. Chi-square test and t test were used for comparisons. RESULTS: Patients who felt that there was a lack of access to cancer care would have sought treatment earlier had they had better access to cancer care (chi-square[1] = 32; p < .0001). Patients who felt that there was a lack of access to cancer care also had difficulty receiving treatment (chi-square[1] = 48; p < .0001). Availability of transportation affected access to cancer care in patients with early-stage cancers (chi-square[1] = 4; p < .035). CONCLUSION: In the postdisaster environment, patients who felt the lack of access to cancer care post-Hurricane Katrina would have sought treatment earlier with better access to cancer care. These patients also reported difficulty obtaining cancer treatment. Availability of transportation affected access to cancer care in patients with early-stage cancers. Clinical, demographic, and socioeconomic factors did not influence access to cancer care.

The effect of AlloDerm on the initiation and growth of human neovessels.

OBJECTIVES/HYPOTHESIS: AlloDerm (LifeCell Corp., Branchburg, NJ) is commonly employed for reconstruction of ablative soft tissue and mucosal defects following surgical resections. Although devoid of growth factors, AlloDerm may serve as an adhesive matrix for binding of growth factors, increasing local angiogenesis, and wound healing. We hypothesized that AlloDerm would enhance angiogenesis and might be altered with autologous blood products to enhance initiation of the angiogenic response. METHODS: We used a human placental vein in a fibrin-thrombin clot-based angiogenesis model. Four groups, human placental vein (HPVM), HPVM with AlloDerm, HPVM with AlloDerm plus platelet-poor plasma, and HPVM with AlloDerm plus platelet-rich plasma were evaluated. Endothelial cell growth was evaluated visually (40x). Hematoxylin and eosin staining and immunofluorescent staining for growth within the AlloDerm matrix were also performed. To assess human umbilical vein endothelial cell (HUVEC) sites of attachment to AlloDerm, we incubated HUVEC cells with AlloDerm for a period of 2 weeks and evaluated attachment with anti-factor VIII immunofluorescence. RESULTS: Angiogenic initiation decreased in the combined placental vein with AlloDerm group (P < .0001 at day 7, 14, 21). Additionally, initiation in the AlloDerm plus platelet-poor plasma group was significantly better than the AlloDerm alone group when placentas 2 and 3 were compared (P < .0001). On hematoxylin and eosin staining and immunofluorescent factor VIII staining, no endothelial growth into the AlloDerm was noted in the samples analyzed. CONCLUSIONS: AlloDerm may be enriched with platelet-poor plasma to stimulate greater initiation and wound healing; however, AlloDerm inhibits angiogenic initiation in this model.

Enhanced hearing in heat-activated-crimping prosthesis stapedectomy.

OBJECTIVES: Compare short-term hearing outcomes with a heat-activated-crimping versus manual-crimping stapedectomy prosthesis. STUDY DESIGN: Retrospective chart review. SETTING: Tertiary care neurotology referral center. PATIENTS: 219 charts reviewed. INTERVENTION: Laser stapedectomy. MAIN OUTCOME MEASURES: Audiometric. METHODS: Retrospective study comparing postoperative hearing in manual-crimp prostheses stapedectomies versus heat-activated-crimp prostheses stapedectomies. RESULTS: Of the 219 patients reviewed, 94 met inclusion criteria for the study, with 47 receiving manual-crimp prosthesis and 47 receiving heat-activated-crimp prosthesis. Short-term poststapedectomy air-bone gaps, long-term air-bone gaps, long-term pure-tone averages, and long-term air-bone gap closures were significantly better for heat-activated-crimp versus manual-crimp prostheses. CONCLUSION: Heat-activated-crimping prostheses demonstrated enhanced stapedectomy hearing outcomes versus manual-crimping prostheses on short- and long-term follow-up. Three-dimensional reorientation of the heat-activated prosthesis may enhance the hearing outcome; however, theoretical nickel allergy considerations, effects of case selection, follow-up duration, possible eventual loosening of the heat-activated crimp, and long-term incus necrosis are considerations requiring continued longitudinal analysis.
