Abstract
PURPOSE Patients with coronary artery disease (CAD) experience significant angina symptoms and lifestyle changes. Revascularization procedures can result in better patient-reported outcomes (PROs) than optimal medical therapy (OMT) alone. This study evaluates the impact of response shift (RS) on changes in PROs of patients with CAD across treatment strategies. METHODS Data were from patients with CAD in the Alberta Provincial Project on Outcome Assessment in Coronary Heart Disease (APPROACH) registry who completed the 16-item Canadian version of the Seattle Angina Questionnaire at 2 weeks and 1 year following a coronary angiogram. Multi-group confirmatory factor analysis (MG-CFA) was used to assess measurement invariance across treatment groups at week 2. Longitudinal MG-CFA was used to test for RS according to receipt of coronary artery bypass grafting (CABG), percutaneous coronary intervention (PCI), or optimal medical therapy (OMT) alone. RESULTS Of the 3116 patients included in the analysis, 443 (14.2%) received CABG, 2049(65.8%) PCI, and the remainder OMT alone. The MG-CFA revealed a partial-strong invariance across the treatment groups at 2 weeks (CFI = 0.98, RMSEA [90% CI] = 0.05 [0.03, 0.06]). Recalibration RS was detected on the Angina Symptoms and Burden subscale and its magnitude in the OMT, PCI, and CABG groups were 0.32, 0.28, and 0.53, respectively. After adjusting for RS effects, the estimated target changes were largest in the CABG group and negligible in the OMT group. CONCLUSION Adjusting for RS is recommended in studies that use SAQ-CAN to assess changes in patients with CAD who have received revascularization versus OMT alone.

Abstract
BACKGROUND Health behaviors, such as diet and exercise, are actions individuals take that can potentially impact gastrointestinal (GI) symptoms and the gut microbiota. Little is known about how health behaviors impact GI symptoms and the gut microbiota after anti-cancer therapies. METHODS This is a secondary analysis of a cross-sectional study that investigated relationships between GI symptoms, gut microbiota, and patient-reported outcomes in adult cancer survivors. Gut microbiota was assessed from stool samples using 16 S rRNA gene sequencing. GI symptoms and health behaviors were measured via self-report. Descriptive statistics, multiple regression, and correlation analyses are reported. RESULTS A total of 334 cancer survivors participated, and a subsample of 17 provided stool samples. Most survivors rated their diet as moderately healthy (55.7%) and reported engaging in low intensity exercise (53.9%) for ≤5 h/week (69.1%). Antibiotic use was associated with more belly pain, constipation, and diarrhea (P < .05). Survivors consuming a healthier diet had fewer symptoms of belly pain (P = .03), gas/bloating (P = .01), while higher protein consumption was associated with less belly pain (P = .03). Better diet health was positively correlated with Lachnospiraceae abundance, and negatively with Bacteroides abundance (P < .05). Greater exercise frequency positively correlated with abundance of Lachnospiraceae, Faecalibacterium, Bacteroides, Anaerostipes, Alistipes, and Subdoligranulum (P < .05). CONCLUSION Results provide evidence for associations between antibiotic use, probiotic use, dietary health behaviors, and GI symptoms. Diet and exercise behaviors are related to certain types of bacteria, but the direction of causality is unknown. Dietary-based interventions may be optimally suited to address survivors' GI symptoms by influencing the gut microbiota. Larger trials are needed.

Abstract
BACKGROUND Neonatal sepsis is an invasive infection of the bloodstream in neonates and a leading cause of morbidity and mortality among them. AIM To investigate the role of procalcitonin (PCT) and C-reactive protein (CRP) in the management of neonatal sepsis. MATERIALS AND METHODS This was a prospective case-control study over one-year period using convenience sampling. Blood samples for PCT and CRP were taken from all neonates, while blood culture and white blood cell count samples were additionally taken from babies with neonatal sepsis. PCT and CRP were repeated at 24 and 48 hours. The continuous variables were found to have a nonparametric distribution. They were presented as median and interquartile range, and compared using Wilcoxon signed rank and Friedman test as appropriate. RESULTS The blood culture analysis yielded a prevalence of 12.7% with Staphylococcus aureus being the commonest organism. Baseline concentrations of PCT (1.28 ng/ml) and CRP (17.31 mg/L) in neonates with sepsis were higher than that of controls (PCT-0.63 ng/ml, CRP-5.40 mg/L). PCT concentrations decreased after two days of antibiotic treatment, while CRP concentrations decreased after a day. The concentration of both decreased to normal levels after two days of treatment. CONCLUSION This study showed that CRP was more reliable in monitoring antibiotic therapy, unlike other studies which suggested PCT. In cases where the management of neonatal sepsis may be limited by a low blood culture yield, therapeutic monitoring may be aided by CRP and/or PCT.

Abstract
BACKGROUND With the seemingly increasing trend of childhood hypertension, high serum uric acid (SUA) levels might be an indicator of essential hypertension among adolescents. OBJECTIVE To determine the SUA levels of hypertensive students and randomly selected controls and find the association, if any, between SUA level and blood pressure (BP) among secondary school students in Ido-Osi Local Government Area (LGA). METHODOLOGY The study was a nested case-control study conducted among selected secondary school students in IdoOsi LGA from June 2017 to March 2018. Of the 573 students screened for hypertension, SUA was assayed from 31 hypertensive students and an equal number of age- and sexmatched controls. Serum uric acid greater than 5.5 mg/ dL was taken as high. Statistical analysis included chi-square and Pearson correlation. RESULTS There was a positive correlation between SUA level and both systolic BP (p < 0.013) and diastolic BP (p < 0.017). The mean (SD) serum uric acid level of the hypertensive students [5.39 (2.08) mg/ dL] was higher than that of the controls [4.24 (1.81) mg/ dL] (p = 0.023). Hypertensive students with hyperuricaemia had a higher mean (SD) systolic BP than those with low uric acid: 138.67 (14.81) versus 128.68 (10.04); p =0.037. CONCLUSION The mean serum uric acid level of students with hypertension was higher than that of the non-hypertensive students and high SUA levels appear to more prominently affect systolic than diastolic blood pressures among the cohort of hypertensive students.

Abstract
BACKGROUND School environment entails the sum total of the physical, biological, social, and emotional environment within which members of the school community operate. It is essential to make the school environment healthy to promote and protect the health of school pupils as well as their safety. This study aimed at finding the level of implementation of a Healthy School Environment (HSE) in Ido/Osi Local Government Area (LGA) of Ekiti State. METHODOLOGY A cross-sectional descriptive study carried out among 48 private and 19 public primary schools using a standardised checklist and direct observation. RESULTS The teacher-to-pupil ratio was 1:16 in public schools and 1:10 in private schools. The leading source of water in 47.8% of the schools was well water. Most, 97%, of the schools practiced open dumping of refuse. Private schools had more school buildings with strong walls and good roofs with doors and windows which provided adequate ventilation compared to the public schools (p- 0.001). No school was located close to an industrial area, however, none had a safety patrol team. Only 34.3% of schools had a fence and 31.3% had terrains prone to flooding. Only 3% of the schools, all private schools, attained the minimum acceptable score on the school environment. CONCLUSION The status of school environment was poor in the study location and school ownership did not make any much impact as there was no difference in the situations of school environment between public and private schools.

Abstract
OBJECTIVE The relationship between antiseizure medications (ASMs), which improve health outcomes by controlling seizures, and health-related quality of life (HRQOL) is poorly understood and may involve intermediate variables. We evaluated the potential mediators of the association between ASMs and HRQOL. METHODS Data are from an outpatient registry of adult patients with epilepsy seen at the Foothills Medical Center, Calgary, Alberta, Canada. Quality of life was measured using the 10-item Quality of Life in Epilepsy, and depression was measured using the Neurological Disorders Depression Inventory for Epilepsy. Propensity score matching was used to adjust for covariate imbalance between patients who received a single ASM (monotherapy) and those who received two or more ASMs (polytherapy) due to confounding. Mediation analysis was used to estimate the mediating effects of depression and ASM side effects on the association between patients' ASM polytherapy and HRQOL. RESULTS Of 778 patients included in this analysis, 274 (35.2%) were on two or more ASMs. Patient-reported depression and ASM side effects jointly mediated the association between ASMs and HRQOL; these mediators accounted for 42% of the total average effect of ASM polytherapy ( β = -13.6, 95% confidence interval = -18.2 to -8.6) on HRQOL. SIGNIFICANCE These findings highlight the importance of managing depression and ASM side effects for improving health outcomes of patients requiring treatment with ASMs. Intervention programs aimed at improving HRQOL of patients with epilepsy need to target these potential mediators.

Abstract
PURPOSE The Seattle Angina Questionnaire (SAQ) is a widely used patient-reported measure of health status in patients with coronary artery disease. Comparisons of SAQ scores amongst population groups and over time rely on the assumption that its factorial structure is invariant. This study evaluates the measurement invariance of the SAQ across different demographic and clinical groups and over time. METHODS Data were obtained from the Alberta Provincial Project on Outcome Assessment in Coronary Heart Disease registry, a registry of patients who received coronary angiogram in Alberta, Canada. The study cohort consists of adult patients who completed the paper-based version of the 16-item Canadian version of the SAQ (SAQ-CAN) 2 weeks and 1-year post-coronary angiogram between 2009 and 2016. Multi-group confirmatory factor analysis was used to assess configural, weak, strong, and strict measurement invariance across age groups, sex, angina type, treatment, and over time. Model fit was assessed using the comparative fit index and root mean square error of approximation. RESULTS Of the 8101 patients included in these analysis, 1300 (16.1%) were at least 75 years old, while 1755 (21.7%) were female, 5154 (63.6%) were diagnosed with acute coronary syndrome, 1177 (14.5%) received coronary artery bypass graft treatment, and 3279 had complete data on the SAQ-CAN at both occasions. There was evidence of strict invariance across age, sex, and angina type, and treatment groups, but partial strict invariance was established over time. CONCLUSION SAQ-CAN can be used to compare the health status of coronary artery disease patients across population groups and over time.

Abstract
OBJECTIVE The 19-item Epilepsy Surgery Satisfaction Questionnaire (ESSQ-19) is a validated and reliable post hoc means of assessing patient satisfaction with epilepsy surgery. Prediction models building on these data can be used to counsel patients. METHODS The ESSQ-19 was derived and validated on 229 patients recruited from Canada and Sweden. We isolated 201 (88%) patients with complete clinical data for this analysis. These patients were adults (≥18 years old) who underwent epilepsy surgery 1 year or more prior to answering the questionnaire. We extracted each patient's ESSQ-19 score (scale is 0-100; 100 represents complete satisfaction) and relevant clinical variables that were standardized prior to the analysis. We used machine learning (linear kernel support vector regression [SVR]) to predict satisfaction and assessed performance using the R2 calculated following threefold cross-validation. Model parameters were ranked to infer the importance of each clinical variable to overall satisfaction with epilepsy surgery. RESULTS Median age was 41 years (interquartile range [IQR] = 32-53), and 116 (57%) were female. Median ESSQ-19 global score was 68 (IQR = 59-75), and median time from surgery was 5.4 years (IQR = 2.0-8.9). Linear kernel SVR performed well following threefold cross-validation, with an R2 of .44 (95% confidence interval = .36-.52). Increasing satisfaction was associated with postoperative self-perceived quality of life, seizure freedom, and reductions in antiseizure medications. Self-perceived epilepsy disability, age, and increasing frequency of seizures that impair awareness were associated with reduced satisfaction. SIGNIFICANCE Machine learning applied postoperatively to the ESSQ-19 can be used to predict surgical satisfaction. This algorithm, once externally validated, can be used in clinical settings by fixing immutable clinical characteristics and adjusting hypothesized postoperative variables, to counsel patients at an individual level on how satisfied they will be with differing surgical outcomes.

Abstract
BACKGROUND The Seattle Angina Questionnaire (SAQ) is a widely-used patient-reported outcomes measure in patients with heart disease. This study assesses the validity and reliability of the SAQ in a Canadian cohort of individuals with stable angina. METHODS AND RESULTS Data are from the Alberta Provincial Project for Outcome Assessment in Coronary Heart Disease (APPROACH) registry, a population-based registry of patients who received cardiac catheterization in Alberta, Canada. The cohort consists of 4052 patients undergoing cardiac catheterization for stable angina and completed the SAQ within 2 weeks. Exploratory factor analysis and confirmatory factor analysis (CFA) were used to assess the factorial structure of the SAQ. Internal and test-retest reliabilities of a new measure (i.e., SAQ-CAN) was measured using Cronbach α and intraclass correlation coefficient, respectively. CFA model fit was assessed using the root mean square error of approximation (RMSEA) and comparative fit index (CFI). Construct validity of the SAQ-CAN was assessed in relation to Hospital Anxiety and Depression Scales (HADS), Euro Quality of life 5 dimension (EQ5D), and original SAQ. Of the 4052 patients included in this analysis, 3281 (80.97%) were younger than 75 years old, while 3239 (79.94%) were male. Both exploratory and confirmatory factor analyses revealed a four-factorial structure consisting of 16 items that provided a better fit to the data (RMSEA = 0.049 [90% CI = (0.047, 0.052)]; CFI = 0.975). The 16-item SAQ demonstrated good to excellent internal reliability (Cronbach's α range from 0.77 to 0.90), moderate to strong correlation with the Original SAQ and EQ5D but negligible correlations with HADS. CONCLUSION The SAQ-CAN has acceptable psychometric properties that are comparable to the original SAQ. We recommend its use for assessing coronary health outcomes in Canadian patients with Coronary Artery Disease.

Abstract
PURPOSE Exercise intervention studies for brain health can be difficult to interpret due to heterogeneity in exercise intensity, exercise duration, and in adherence to the exercise intervention. This study aimed to characterize heterogeneity in these components in a cohort of healthy middle-age and older adults who participated in a prescribed 6-month supervised aerobic exercise intervention as part of the Brain in Motion study. METHODS AND RESULTS Group-based multitrajectory analysis (GBMTA) was used to characterize variation in the trajectory of exercise intensity and duration for male and female participants in the first 3 months of the exercise program. The GBMTA for males and females revealed two distinct trajectory subgroups, namely, "high-increasing" (HI) and "low-increasing" (LI). Logistic regression was used to assess the association between the identified latent subgroups and (i) demographic characteristics; (ii) physiological characteristics, including cardiovascular and cerebrovascular function; (iii) genetic characteristics; and (iv) adherence with American College of Sports Medicine guidelines on exercise for older adults. Of the 196 participants, 54.1% met the American College of Sports Medicine aerobic exercise targets for intensity and duration during the intervention. Aerobic fitness (maximal oxygen uptake; odds ratio, 1.27; P < 0.01) was significantly different between these trajectory subgroups in males, and cerebrovascular function (cerebrovascular resistance; odds ratio, 0.14; P < 0.01) was significantly different between these trajectory subgroups in females. CONCLUSION This novel approach to tracking a prespecified exercise program highlights that there are individual and group-specific variations within a prescribed exercise intervention. Characterizing exercise adherence in this way holds promise in developing optimized exercise prescriptions tailored to individual baseline characteristics, and additionally highlighting those participants at greatest risk of not meeting minimum dosage requirements for physiological and/or cognitive health.

Abstract
Gunnera perpensa L. (Gunneraceae) is a medicinal plant used by Zulu traditional healers to stimulate milk production. The effect of an aqueous extract of the rhizome of the plant on milk production in rats was investigated. Female lactating rats that received oral doses of the extract of G.perpensa significantly (p<0.05) produced more milk than controls. The plant extract did not however, significantly influence the levels of prolactin, growth hormone, progesterone, cortisol, ALT, AST and albumin in the blood. The mammary glands of rats treated with the extract showed lobuloalveolar development. The extract (0.8 µg/ml) was also found to stimulate the contraction of the uterus and inhibit (23%) acetylcholinesterase activity. The cytotoxicity of the extract (LC₅₀) to two human cell lines (HEK293 and HepG2) was 279.43 µg/ml and 222.33µg/ml, respectively. It is inferred that the plant extract exerts its activity on milk production and secretion by stimulating lobuloalveolar cell development and the contraction of myoepithelial cells in the alveoli. It is concluded that Gunnera perpensa contains constituents with lactogenic activity that apparently contribute to its effectiveness in folk medicine.
