IntroductionHigh blood pressure (BP) post-thrombolysis has been associated with an increased rate of bleeding and poorer outcome. We noted frequent BPs of >180 mmHg with a target of keeping BP <180. We tested whether a more aggressive target of SBP <160 mmHg would result in fewer BP protocol violations.MethodsPatients were prospectively captured comparing patients thrombolysed during the 12 months before and 12 months following the introduction of a new more aggressive BP protocol, allowing for a 6 month transition period. Results were adjusted for baseline function and stroke severity using regression analysis.ResultsPre-protocol change 68 and post- 100 patients were thrombolysed. Baseline characteristics were similar between groups. There was a trend for a lower rate of SBPs >180 mmHg (adjusted OR 0.49; 95% CI 0.31–1.1; p=0.097) and a significantly higher rate of SBPs <120 mmHg (adjusted OR 3.06; 95% CI 1.52–6.17; p=0.002) in the aggressive BP protocol group; although events of extreme SBPs (>200 and <100 mmHg) were similar between groups. Favourable outcomes (mRS = 0–2) at 3 months were similar between groups (adjusted OR 1.27; 95% CI 0.58–2.8; p=0.56) as was the rate of symptomatic haemorrhages (adjusted OR 1.26; 95% CI 0.28–5.7; p=0.76). Model fit was improved by adding study group to the model.ConclusionsMore aggressive post-thrombolysis BP management lowered the overall BP, but did not result in improved patient outcomes. Potential explanations include a small sample size, reduced cerebral perfusion off-setting reduced bleeding risk, or high BP being merely an epiphenomenon of worse outcome rather than causative.

The Impact

Background: A reduction of 10 mm Hg in systolic blood pressure (SBP) significantly decreases the risk of major cardiovascular disease events. Pharmacists’ management of blood pressure may assist with this reduction. Objective: Assess the impact of pharmacist management of hypertension via a collaborative practice agreement with physicians in an ambulatory care clinic. Methods: The first phase of this study was a retrospective chart review of physician/nurse hypertension visits from October 2019 to August 2020. The second prospective phase consisted of pharmacist managed hypertension visits from December 2020 to January 2021. The primary outcome was the change in SBP from the beginning to the end of the study period in the prospective group. Secondary outcomes included the proportion of patients achieving their blood pressure goal and the proportion of patients adherent to all antihypertensive medications at their follow-up visits in both groups. This study was institutional review board approved. Results: Forty-seven patients were included and analyzed (24 in the retrospective group and 23 in the prospective group). Patients in the prospective group had an average SBP lowering of 10.83 mm Hg ( P = .0035). Thirteen patients (56.5%) met their blood pressure goal of <130/80 mm Hg in the prospective group, compared to 5 patients (20.8%) in the retrospective group ( P = .012). One adverse event occurred during this study. Limitations included small sample size and short duration of study. Conclusion: Patients had an average SBP lowering of >10 mm Hg. More patients reached a goal blood pressure of <130/80 mm Hg when managed by pharmacists.

AbstractIntroduction. The COVID-19 is the name of an infectious disease caused by a new strain of coronavirus SARS-CoV-2 (Severe Acute Respiratory Syndrome Coronavirus 2). It was first diagnosed in December 2019 in patients in Wuhan City, Hubei Province, China. The symptoms are dominated by features of respiratory tract infections, in some patients with a very severe course leading to respiratory failure and, in extreme cases to death. Due to the spread of the infection worldwide, the WHO declared a pandemic in March 2020.Aim. An investigation of the impact of social isolation introduced due to the coronavirus pandemic on selected aspects of life. The researchers focused on observing changes in habits related to physical activity and their connections with people’s subjective well-being and emotional state.Material and methods. The study was carried out within the international project of the group „IRG on COVID and exercise”. The research tool was a standardized questionnaire.Results. Based on the data collected and the analysis of the percentage results, it can be observed that the overwhelming majority of people taking up physical activity reported a better mood during the pandemic. However, statistical tests do not confirm these relationships due to the small sample size.Conclusions. Isolation favours physical activity. Future, in-depth studies, by enlarging the population group, are necessary to confirm the above observations.

The Impact

Previous studies have identified that a behavior can occur through the strongest predictor intention, but there is a gap between intention and behavior. Dopamine receptor D2 (DRD2) is known to account for a variance in sporting behaviors in human and animal subjects. However, the relationship between DRD2 and sport participation has been poorly studied, and the limited available reports are inconsistent. The present study was performed to examine the impact of DRD2 on sport participation among Korean university students based on the integrated behavioral model (IBM). Data were collected from enrolled university students in Seoul (N = 45). Participants answered survey questions first, and then they gave investigators their hair to provide DNA information (i.e., the A1 allele of DRD2). DRD2 had a significant effect on sport participation, but only in male students. Male students who carried the A1 allele of DRD2 significantly participated in 105.10 min more sporting activities than male students who did not. Moreover, the effect of intention on sport participation was significantly decreased when considering DRD2. Despite the small sample size, the results of this study could be a preliminary case for a larger study and indicate the direction of future research. Our results suggest that DRD2 may have played an important role as the “actual skill” shown in the IBM.

Background: Simultaneous kidney-pancreas transplantation (SPK) has benefits for patients with kidney failure and type I diabetes mellitus, but is associated with greater perioperative risk compared with kidney-alone transplantation. Postoperative care settings for SPK recipients vary across Canada and may have implications for patient outcomes and hospital resource use. Objective: To compare outcomes following SPK transplantation between patients receiving postoperative care in the intensive care unit (ICU) compared with the ward. Design: Retrospective cohort study using administrative health data. Setting: In Alberta, the 2 transplant centers (Calgary and Edmonton) have different protocols for routine postoperative care of SPK recipients. In Edmonton, SPK recipients are routinely transferred to the ICU, whereas in Calgary, SPK recipients are transferred to the ward. Patients: 129 adult SPK recipients (2002-2019). Measurements: Data from the Canadian Institute for Health Information Discharge Abstract Database (CIHI-DAD) were used to identify SPK recipients (procedure codes) and the outcomes of inpatient mortality, length of initial hospital stay (LOS), and the occurrence of 16 different patient safety indicators (PSIs). Methods: We followed SPK recipients from the admission date of their transplant hospitalization until the first of hospital discharge or death. Unadjusted quantile regression was used to determine differences in LOS, and age- and sex-adjusted marginal probabilities were used to determine differences in PSIs between centers. Results: There were no perioperative deaths and no major differences in the demographic characteristics between the centers. The majority of the SPK transplants were performed in Edmonton (n = 82, 64%). All SPK recipients in Edmonton were admitted to the ICU postoperatively, compared with only 11% in Calgary. There was no statistically significant difference in the LOS or probability of a PSI between the 2 centers (LOS for Edmonton vs Calgary:16 vs 13 days, P = .12; PSIs for Edmonton vs Calgary: 60%, 95% confidence interval [CI] = 0.50-0.71 vs 44%, 95% CI = 0.29-0.59, P = .08). Limitations: This study was conducted using administrative data and is limited by variable availability. The small sample size limited precision of estimated differences between type of postoperative care. Conclusions: Following SPK transplantation, we found no difference in inpatient outcomes for recipients who received routine postoperative ICU care compared with ward care. Further research using larger data sets and interventional study designs is needed to better understand the implications of postoperative care settings on patient outcomes and health care resource utilization.

To the Editor.— I wish to comment on the study reported by Cronenwett et al,1 which was a fascinating prospective study among married white women who planned to breast-feed. Women were randomly selected to perform either exdusive breast-feeding or partial breast-feeding with bottled human milk supplements to determine the impact of infant temperament and limited bottle-feeding on breast-feeding duration. The authors admit that small sample size and lack of statistical power make a false-negative possible.

Caloric Tests

Abstract Objectives Idiopathic sudden sensorineural hearing loss (SSNHL) represents a frequently encountered otological entity, of various types and severity, with an array of associated symptoms including vertigo. This is a devastating life-changing condition with a blurry prognosis. The objective of this study was to determine the clinical association of vestibular impairment by electronystagmography (ENG) and caloric tests, and their ability to predict prognosis. Methods An observational, crossectional study was carried out amongst patients admitted with SSNHL. Each consenting patient had an audiometry test performed on admission as well as ENG and caloric tests. Treatment included oral steroids and carbogen with intratympanic steroids used only as salvage treatment. Follow-up was completed after 6 months when hearing gains were evaluated. Finally, an association was sought between the rate of recovery and ENG and caloric test results. Results Of 35 patients included, marked recovery was seen in patients without vertigo when compared to those with vertigo (p=0.003). A statistically significant association was found between the presence of vertigo and hearing deterioration (p=0.008). More so, normal electronystagmography results were associated with marked recovery (p=0.04). Conclusions The vestibular end organs are both subjectively and objectively affected in SSNHL as demonstrated by the abnormal ENG and caloric tests in our study despite the small sample size. Concomitant vestibular involvement carries poorer prognosis and routine identification may help foresee the recovery of patients with SSNHL and as such, aid in patient counseling. ENG and caloric tests are easily available and may be recommended for all patients with SSNHL.

Background: Per American Heart Association guidelines, blood pressure (BP) should be < 185/110 to be eligible for intravenous tissue plasminogen activator (tPA). It is shown that door to needle (DTN) time is prolonged in patients who require anti-hypertensive medications prior to thrombolysis in the emergency department (ED). To our knowledge, no studies have focused on pre-hospital BP and its impact on DTN times. We hypothesize that DTN times are longer for patients with higher pre-hospital BP. Methods: We conducted a retrospective review of acute ischemic stroke patients who presented between 1/2010 and 12/2010 to our ED through Emergency Medical Services (EMS) within 3-hrs of symptom onset. Patients were identified from our registry and categorized into two groups: Pre-hospital BP ≥ 185/110 (Pre-hsp HBP) and < 185/110 (Pre-hsp LBP). BP records were abstracted from EMS sheets. Two groups were compared using two-sample t-test or Wilcoxon rank sum test for continuous variables and Chi-square test or Fisher’s exact test for categorical variables. Results: A total of 107 consecutive patients were identified. Out of these, 75 patients (70%) were treated with tPA. Among the patients who received thrombolysis, 35% had pre-hospital BP ≥ 185/110 (n= 26/75). Greater number of patients required anti-hypertensive medications in ED in high BP group compared to low BP group (Pre-hsp HBP n= 14/26, 54%; Pre-hsp LBP n= 13/49, 27%, p < 0.02). Mean door to needle times were significantly higher in Pre-hsp HBP group. (mean ± SD 87.5± 34.2 Vs. 59.7±18.3, p<0.0001). Analysis of patients only within the Pre-hsp HBP group (n= 26) revealed that DTN times were shorter if patients received pre-hsp BP medications compared to patients in the same group who did not receive pre-hsp BP medication (n= 10 vs 16; mean ± SD 76.5 ± 25.7 Vs. 94.3 ± 37.7, p = 0.20) Conclusion: Higher pre-hospital BP is associated with prolonged DTN times and it stays prolonged if pre-hospital high BP remains untreated. Although the later finding was not statistical significant due to small sample size, pre-hospital blood pressure control could be a potential area for improvement to reduce door to needle times in acute ischemic stroke.

The Relationship

Purpose The purpose of this paper is to focus on the moderating effect of mandatory International Financial Reporting Standards (IFRS) adoption on the relationship between chief executive officer (CEO) experience/education and earnings management in European companies. Design/methodology/approach Data from a sample of 302 European firms listed on Stoxx Europe 600 index and 596 CEOs from 2000 to 2014 are used to test the moderation model using moderation regression analysis. Findings Evidence reveals that CEO’s accounting-based attributes are negatively associated with accruals-based earnings management and positively associated with real earnings management (REM). Further, mandatory IFRS adoption significantly moderates the impact of CEO’s accounting-based traits on earnings-management activities. Research limitations/implications A small number of European firms were studied and, given the long study period, many firms with missing data were eliminated. To avoid a small sample size, countries with few observations were included, which leads to an uneven distribution between observations per country. Practical implications Findings from this paper can help: European firms to consider demographic traits when recruiting or promoting executives; the IASB to improve enforcement mechanisms and make IFRS implementation mandatory; and audit committees to effectively monitor REM. Originality/value This study is unique in providing European evidence for the moderating effect of mandatory IFRS adoption on the relationship between CEOs’ accounting experience/education and earnings management activities. This paper is also relevant as it addresses the effectiveness and efficiency of accounting literates.

Abstract In the newborn, penile length is determined by a number of androgen dependent and independent factors. The current literature suggests that there are inter-racial differences in stretched penile length in the newborn and although congenital micropenis should be defined as a stretched penile length of less than 2.5SDS of the mean for the corresponding population and gestation, a pragmatic approach would be to evaluate all boys with a stretched penile length below 2 cm, as congenital micropenis can be a marker for a wide range of endocrine conditions. However, it remains unclear as to whether the state of micropenis, itself, is associated with any long-term consequences. There is a lack of systematic studies comparing the impact of different therapeutic options on long-term outcomes, in terms of genital appearance, quality of life and sexual satisfaction. To date, research has been hampered by a small sample size and inclusion of a wide range of heterogeneous diagnoses; for these reasons, condition specific outcomes have been difficult to compare between studies. Lastly, there is a need for a greater collaborative effort in collecting standardized data so that all real-world or experimental interventions performed at an early age can be studied systematically into adulthood.

The Impact

The aim of this review was to evaluate the literature that has investigated the impact of visual impairment on nutritional status. We identified relevant articles through a multi-staged systematic approach. Fourteen articles were identified as meeting the inclusion criteria. The sample size of the studies ranged from 9 to 761 participants. It was found that visual impairment significantly affects nutritional status. The studies reported that visually impaired people have an abnormal body mass index (BMI); a higher prevalence of obesity and malnutrition was reported. Visually impaired people find it difficult to shop for, eat, and prepare meals. Most studies had a small sample size, and some studies did not include a study control group for comparison. The limitations of these studies suggest that the findings are not conclusive enough to hold true for only those who are visually impaired. Further studies with a larger sample size are required with the aim of developing interventions.
