ABSTRACT

INTRODUCTION: Epilepsy places a large burden on health systems, with hospitalisations for seizures alone occurring more frequently than those related to diabetes. However, the cost of epilepsy to the Australian health system is not well understood. The primary aim of this study is to quantify the health service use and cost of epilepsy in Queensland, Australia. Secondary aims are to identify differences in health service use and cost across population and disease subgroups, and to explore the associations between health service use and common comorbidities.

METHODS AND ANALYSIS: This project will use data linkage to identify the health service utilisation and costs associated with epilepsy. A base cohort of patients will be identified from the Queensland Hospital Admitted Patient Data Collection. We will select all patients admitted between 2014 and 2018 with a diagnosis classification related to epilepsy. Two comparison cohorts will also be identified. Retrospective hospital admissions data will be linked with emergency department presentations, clinical costing data, specialist outpatient and allied health occasions of service data and mortality data. The level of health service use in Queensland, and costs associated with this, will be quantified using descriptive statistics. Difference in health service costs between groups will be explored using logistic regression. Linear regression will be used to model the associations of interest. The analysis will adjust for confounders including age, sex, comorbidities, indigenous status, and remoteness.

ETHICS AND DISSEMINATION: Ethical approval has been obtained through the QUT University Human Research Ethics Committee (1900000333). Permission to waive consent has been granted under the Public Health Act 2005, with approval provided by all relevant data custodians. Findings of the proposed research will be communicated through presentations at national and international conferences, presentations to key stakeholders and decision-makers, and publications in international peer-reviewed journals.

ABSTRACT

OBJECTIVE: Observational studies have suggested a beneficial effect of taking statins on frequency of chronic obstructive pulmonary disease (COPD) exacerbations. However, clinical trials of statins in people with COPD did not confirm those results. This study aimed to investigate this association using a methodological approach, which reduces the biases associated with some previous observational study designs.

DESIGN: Retrospective cohort study comparing new-users of statins with non-users.

SETTING: General practices in England contributing to the Clinical Practice Research Datalink in 2007-2017, with linkage to data on Hospital Episode Statistics inpatient episodes.

PARTICIPANTS: 48 124 people with COPD, aged over 40 years, who had not been prescribed statin in the previous year.

EXPOSURE: Participants became new-users of statins at their first prescription for a statin during follow-up. They were then assumed to remain statin users. Statin users were compared with non-users.

OUTCOMES: Primary outcomes were COPD exacerbation, or severe exacerbation requiring hospitalisation. Secondary outcomes were death from any cause (for comparison with other studies) and urinary tract infection (negative-control). Maximum follow-up was 3 years. Adjusted HR were calculated using time-dependent Cox regression. The Andersen-Gill model was used for recurrent exacerbations. Covariates included demographic variables, variables related to COPD severity, cardiovascular comorbidities as time-dependent variables, and other comorbidities at baseline.

RESULTS: 7266 participants became new-users of statins over an average 2.5 years of follow-up. In total, 30 961 people developed an exacerbation, 8110 severe exacerbation, 3650 urinary tract infection and 5355 died. Adjusted HR (95% CI) in statin users compared with non-users were first exacerbation 1.01 (0.96-1.06), severe exacerbation 0.92 (0.84-0.99), number of exacerbations 1.00 (0.97-1.04), urinary tract infection 1.10 (0.98-1.23) and death 0.63 (0.57-0.70).

CONCLUSIONS: In this study of health records from a Primary Care database, statin use in people with COPD was not associated with a lower risk of COPD exacerbation.

ABSTRACT

BACKGROUND: The Edmonton Obesity Staging System (EOSS) combined with body mass index (BMI) enables improved functional and prognostic assessment for patients. To facilitate application of the EOSS in practice, we aimed to create tools for capturing comorbidity assessments in electronic medical records and for automating the calculation of a patient’s EOSS stage.

METHODS: In this feasibility study, we used cross-sectional data to create a clinical dashboard to calculate and display the relation between BMI and EOSS and the prevalence of related comorbidities. We obtained data from the Northern Alberta Primary Care Research Network and the Canadian Primary Care Sentinel Surveillance Network (CPCSSN). We included patients at least 18 years of age with BMI between 30 and 60 who visited a network clinic between July 2016 and July 2019. We calculated descriptive statistics and used stepwise ordinary least squares regression to assess the contributions of age, sex and BMI to EOSS variation.

RESULTS: We created a clinical dashboard using the CPCSSN data presentation tool. Of the total 31 496 patients included in the study, 23 460 had a BMI of at least 30; BMI was unavailable for 8036 patients. Within each EOSS disease severity stage, there were similar proportions of patients from each BMI class (e.g., patients with EOSS stage 2 included 51.8% of those with BMI class I, 55.3% of those with BMI class II and 58.8% of those with BMI class III).

INTERPRETATION: Using data from primary care electronic medical records, it was feasible to create a clinical dashboard for obesity that highlighted the severity and stage of obesity. Making this information easily accessible for individual clinical care and practice-level quality improvement may advance obesity care.

ABSTRACT

OBJECTIVE: To investigate the reliability and validity of Healthy Fitness Measurement Scale Version 1.0 (HFMS V1.0) for different population cohorts in the city of Guangzhou, Guangdong, China and to provide evidence and tools for further evaluation of healthy fitness of Chinese population and related factors.

DESIGN: Cross-sectional study.

SETTING: Urban neighbourhood and Medical University.

PARTICIPANTS: Elderly people (n=393; mean age 68.27±6.38 years; 53.18% male), university students (n=390; mean age 19.29±1.29 years; 38.21% male) and urban residents (n=393; mean age 32.23±9.41 years; 44.78% male).

PRIMARY AND SECONDARY OUTCOME MEASURES: The primary outcomes were evaluated the reliability and validity of HFMS V1.0 by internal consistency evaluation, split-half reliability, test-retest reliability, convergent and discriminant construct validity, and factor analysis.

RESULTS: The Cronbach’s α coefficients for HFMS V1.0 were all greater than 0.85 for overall scale of total samples and three individual groups, and the split-half reliability and intragroup correlation coefficients were both greater than 0.70 (p<0.01). The correlation of each item, dimension and subscales ranged from 0.52 to 0.91 (p < 0.01). A total of 10 factors were screened by exploratory factor analysis with the cumulative contribution rate of 61.40%, basically consistent with the theoretical structure of scale. The confirmatory factor analysis indicated good fit: CMIN/DF=3.45, root mean square error of approximation=0.05, GFI=0.91, AGFI=0.90, IFI=0.90, comparative fit index=0.90.

CONCLUSION: HFMS V1.0 showed acceptable reliability and validity in the test of healthy fitness of general population in Guangzhou. This scale could be a reliable measurement tool for evaluation of healthy fitness and potential risk factors.

ABSTRACT

BACKGROUND: Proton pump inhibitors (PPI) are the most commonly used medication in the world. They are prescribed as an effective treatment choice for gastrointestinal system diseases linked to hyperacidity, especially. Additionally, non-indication and unnecessary use are very common. Many publications in recent times have reported significant side effects. However, there are insufficient studies about the mechanism for these side effects.

METHODS: Twenty-four Wistar albino rats were used in this study. Rats were divided into 3 groups of control, group-administered H2 receptor blockers and a group-administered PPI. Medications were administered for 30 days intraperitoneal. After 30 days, rats were euthanized and lung tissue was obtained. Lung was stained for immunohistochemical catalase, superoxide dismutase, Glutathione peroxidase, myeloperoxidase, and toluidine blue and investigated with a light microscope. Transmission electron microscopy (TEM) was used to investigate lung tissues and neutrophil leukocytes. Additionally, lung tissue had biochemical hydrogen peroxide (H2O2) levels researched.

RESULTS: H2O2 amounts, produced by lysosomes with important duties for neutrophil functions in lung tissues, were found to be statistically significantly reduced in the group-administered PPI. Results from investigations of specimens obtained with immunohistochemical staining observed increases in antioxidant amounts in the PPI group. Investigation with TEM identified more inflammation findings in the lung tissue from the group-administered PPI compared to the control group and the group-administered H2 receptors.

CONCLUSION: In conclusion, we identified long-term PPI use disrupts neutrophil leukocyte functions in the lung. All clinicians should be much more careful about PPI use.

ABSTRACT

BACKGROUND: Radial neck fracture in children is rare. This study attempted to evaluate the outcome of surgically treated patients and any associated complications.

METHODS: This study evaluated 23 children under 15 years of age with radial neck fracture who were treated with open reduction between 2006 and 2016 to determine their range of motion, postoperative complications, and radiographic outcomes. The results were assessed clinically using the Mayo clinic elbow performance score.

RESULTS: The mean follow-up duration for patients was 34.6 months. The average postoperative angulation was 3.6°. Hypoesthesia was reported in only 9% of patients, and none of the patients complained of postoperative pain. The postoperative X-ray results were excellent in 60% and good in 40%. No radiographic complications were identified. The elbow score was excellent in 87% and good in 13% (mean score, 96.74). There was a statistical relationship between range of motion limitations and age, degree of fracture, initial displacement, and surgical pin removal time.

CONCLUSIONS: Although most patients accept the closed reduction method as a primary treatment, the present study suggests that an open-reduction approach has been associated with optimal therapeutic outcomes for patients in whom closed reduction was not satisfactory or indicated.

ABSTRACT

From evolution, thin-layer chromatography (TLC) attracts attention as a versatile technique for efficient separation and identification of many drug substances and chemicals. Owing to its simplicity and other outstanding advantages, TLC is extensively used by chromatographers in quantification and purity profiling objectives. In the present study two TLC-Densitometric methods are established and validated for the synchronous estimation of Cinnarizine (Cinn) and Acefyline Heptaminol (Acef) in the presence of Cinn/Acef reported degradation products and Thoephylline (Theo) as Acef potential impurity. The proposed methods are based on densitometric measurements of the spots of Cinn and Acef after separation from their degradation products. Separation is attained on silica gel sheet with dichloromethane: methanol: formic acid as a developing system in ratio: (15, 1, 0.5, by volume) and (15, 0.75, 0.4, by volume) for Cinn (method 1) and Acef (method 2) degradation, consecutively. Quantification is done at 254 nm over concentration ranges of 0.2-1.8 and 2-18 μg/spot for Cinn and Acef; respectively, with mean percentage recoveries of 99.18 ± 0.60/99.84 ± 0.53 and 99.19 ± 0.93/99.66 ± 0.58 for method 1 and method 2; consecutively. The two methods are fully validated and proven to be selective, robust and retained their accuracy in up to 50% of Cinn/Acef reported degradation products and Theo. Moreover, the two methods are applied to a coformulated drug product comprising Cinn and Acef showing satisfactory results. Comparison of the obtained results by the proposed methods with that of the reference ones statistically shows no significant differences.

ABSTRACT

BACKGROUND: We aimed to assess the effect of plate hook bending in treatment of acromioclavicular (AC) dislocation by analyzing clinical and radiological results according to the angle of the plate hook (APH).

METHODS: This was a retrospective, observational, case-control study including 76 patients with acute AC joint dislocation that were divided into two groups according to treatment with bent or unbent plate hook. The visual analog scale (VAS), the American Shoulder and Elbow Surgeons (ASES) shoulder score, and range of motion (ROM) were evaluated as clinical outcomes. Comparative coracoclavicular distance (CCD) was measured to evaluate radiological outcomes.

RESULTS: While the VAS and ASES of the bending group at 4 months after surgery were significantly higher (p=0.021 and p=0.019), the VAS and ASES of the bending group at other periods and ROM of the bending group showed no significant difference. The initial CCD decreased from 183.2%±25.4% to 114.3%±18.9% at the final follow-up in the bending group and decreased from 188.2%±34.4% to 119.1%±16.7% in the non-bending group, with no statistical difference (p=0.613). The changes between the initial and post-metal removal CCD were 60.2%±11.2% and 57.3%±10.4%, respectively, with no statistical difference (p=0.241). The non-bending group showed greater subacromial osteolysis (odds ratio, 3.87). Pearson’s coefficients for the correlation between APH and VAS at 4 months after surgery and for that between APH and ASES at 4 months after surgery were 0.74 and -0.63 (p=0.027 and p=0.032), respectively.

CONCLUSIONS: The APH was associated with improved postoperative pain and clinical outcomes before implant removal and with reduced complications; therefore, plate hook bending is more useful clinically during plate implantation.

ABSTRACT

Postoperative morbidity following esophagectomy remains substantial. Studies in major abdominal surgery have shown that prehabilitation can improve postoperative outcomes. This single-center study investigated the influence of prehabilitation on postoperative outcomes in patients undergoing minimally invasive Ivor-Lewis esophagectomy (MIE-IL). Data were collected on patients that underwent a MIE-IL and received a fully standardized enhanced recovery after surgery (ERAS) program, between October 2015 and February 2020. The intervention group comprised patients enrolled in the PREPARE prehabilitation program. The control group comprised a retrospective cohort with similar ERAS care, prior to implementation of PREPARE. Postoperative outcomes included (functional) recovery, length of hospital stay (LOHS), cardiopulmonary complications (CPC) and other predefined outcomes. The PREPARE group comprised 52 and control group 43 patients. Median time to functional recovery was 6 vs. 7 days (P = 0.074) and LOHS 7 vs. 8 days (P = 0.039) in PREPARE and control patients, respectively. Hospital readmission rate was 9.6 vs. 14.3% (P = 0.484). A 17% reduction in thirty-day overall postoperative complication rate was observed in PREPARE patients, but this was not statistically significant (P = 0.106). Similarly, a clinically relevant reduction of 14% in CPC rate was observed (P = 0.190). Anastomotic leakage rate was similar (9.6 vs 14.0%; P = 0.511). Despite no difference in severity (Clavien-Dindo) of complications (P = 0.311), ICU readmission rate was lower in PREPARE patients (3.8 vs. 16.3%, P = 0.039). Prehabilitation prior to MIE-IL led to a shorter LOHS and reduced ICU readmission rate. Additionally, a clinically relevant improvement in postoperative recovery and reduced morbidity rate was observed in prehabilitated patient.

ABSTRACT

OBJECTIVE: In this study, we aimed to assess anxiety and sleep quality in cancer patients treated or followed up at our clinic at the time of the outbreak of the COVID-19 pandemic.

METHODS: Seven hundred and sixty-one patients who were either treated or followed up at our oncology clinic between April 2020 and May 2020 were included. Patients were assessed with the State-Trait Anxiety Inventory (STAI) and the Pittsburgh Sleep Quality Index (PSQI).

RESULTS: Mean scores of the 761 participants were STAI, 43.45 ± 9.34 (range, 23-75), and PSQI, 5.67 ± 4.24 (range, 0-19). Quality of sleep was found bad in 447 (58.7%) (global score ≥5). Univariate analyses demonstrated statistical differences by stage of cancer, status of treatment, subgroup of treatment, monthly income, and levels of education in anxiety and sleep quality levels. Multivariate analyses showed active treatment (OR: 21.4; 95% CI: 9.08-50.4; p < 0.001) as the major independent variable that affected sleep quality; the major independent variable associated with anxiety was low income (OR: 4.43; 95% CI: 1.69-11.5; p = 0.002).

CONCLUSION: Anxiety and sleep quality levels were found comparable to pre-pandemic reports, and the pandemic was not observed to have additional negative impact on cancer patients. Also, universal basal anxiety and sleep disorder that accompany cancer or active treatment were observed in our study. The accurate effects of the pandemic can be analyzed in further studies using repeated data obtained from the same patient group.
