Workplace cardiovascular risk reduction by healthcare professionals-a systematic review.

BACKGROUND: Cardiovascular disease has a significant impact on public health and is largely preventable by addressing modifiable risk factors. As most adults spend on average half of their waking hours at work, this provides a significant opportunity to address modifiable risk factors through health promotion interventions. Healthcare professionals have the knowledge and skills to provide workplace interventions aimed at cardiovascular risk reduction. AIMS: This study was aimed to assess the literature regarding the effect of workplace interventions led by healthcare professionals on cardiovascular risk factors. METHODS: Cumulative Index to Nursing and Allied Health Literature (CINAHL), Embase, MEDLINE, PsycINFO and SPORTDiscus were systematically searched from inception to March 2021. Included studies evaluated impact of workplace interventions by healthcare professionals on cardiovascular health. Data on study design, baseline characteristics, interventions, outcomes and conclusions were extracted and qualitatively analysed. RESULTS: Forty-five studies representing 77 633 participants were included in the analysis. Healthcare professionals involved included: nurses, nurse practitioners, physicians, dietitians, pharmacists, physician assistants, medical technicians/emergency medical technicians and physiotherapists. Workplace interventions by healthcare professionals generally improved surrogate markers of cardiovascular health. Success varied based on provider and nature of the intervention. Addressing motivation and including follow-up were key factors for successful intervention to reduce cardiovascular risk factors. CONCLUSIONS: Workplace health promotion initiatives delivered by healthcare professionals may improve cardiovascular risk markers if they are evidence based and customized for target populations. More research is needed to determine clinical relevance of interventions and ideal interventions for specific employee groups.

Patterns of medication use before, during and after pregnancy in women with systemic lupus erythematosus: a population-based cohort study.

OBJECTIVES: This study aimed to characterize the patterns of medication use before, during and after pregnancy in a population-based cohort of women with systemic lupus erythematosus (SLE). METHODS: Using population-based administrative data in British Columbia, Canada, with valid information on start date of pregnancy, we identified women with SLE who had singleton pregnancies ending in deliveries between January 1, 2002, and December 31, 2012. We assessed the proportion of SLE pregnancies exposed to SLE medications - namely antimalarials and immunosuppressants - as well as glucocorticosteroids, and nonsteroidal anti-inflammatory drugs (NSAIDs) 24 months before pregnancy, each trimester of pregnancy, and 12 months postpregnancy. We also assessed discontinuation of antimalarials and immunosuppressants, defined as no prescriptions in a given window following a prescription in a preceding window. RESULTS: Of 376 pregnancies (284 women) with SLE, 24.2% had one or more dispensing for antimalarials, 8.2% for azathioprine, 19.7% for glucocorticosteroids and 4.8% for NSAIDs during pregnancy. We observed a 16.7% discontinuation of antimalarials in the year prior to pregnancy, 29.8% in the first trimester, 9.7% in the second trimester, and 26.0% in the third trimester. We also observed a 29.2% discontinuation of azathioprine in the first trimester, 8.0% in the second trimester, and 9.1% in the third trimester. CONCLUSIONS: These population-based data show frequent discontinuation of medications, particularly antimalarials, in SLE pregnancies. These findings suggest the importance of educating women with SLE who are pregnant or planning to become pregnant on the benefits and risks of medications during pregnancy.

Effect of angiotensin converting enzyme inhibition on the Doppler waveform in dogs with renal artery stenosis.

Our objective was to investigate whether the angiotensin converting enzyme inhibitor enalaprilat improves detection of hemodynamically significant renal artery stenoses in dogs. Renal artery stenoses of 50 to 99% were surgically created unilaterally in five dogs. Doppler ultrasonographic evaluation was performed at baseline (no stenosis), after creation of the stenosis, and after the administration of enalaprilat. The resistive index increased in the nonstenotic kidney (P < 0.01) but not in the stenotic kidney after administration of enalaprilat. The difference in resistive indices between nonstenotic and stenotic kidneys increased significantly (P < 0.05) after administration of enalaprilat. Measurement of the resistive index after administration of an angiotensin converting enzyme inhibitor in humans may improve the performance of Doppler ultrasonography in detecting hemodynamically significant renal artery stenoses.

Correlation of functional magnetic source imaging with intraoperative cortical stimulation in neurosurgical patients.

This study compared noninvasive preoperative functional imaging by using magnetoencephalography (MEG) with intraoperative direct cortical stimulation in ten patients undergoing neurosurgery. The goal was to assess the accuracy and reliability of MEG-based functional imaging in these patients as a possible replacement or adjunct for direct cortical stimulation with electrocorticography. Objective comparison of intraoperative mapping with preoperative MEG procedures was achieved by intraoperative recording of mapped cortical locations for motor responses using an interactive image-guided surgical device, the ISG viewing wand, with which mapping points could be marked on a previously acquired (MRI) set. In all ten patients, at least one stimulation site elicited a response during both MEG and intraoperative mapping. The central sulcus ipsilateral to the lesion was only directly visible on high-resolution MRIs in 3/10 cases and equivocally in 2/10. Coregistered with MRI to form magnetic source images (MSIs), MEG predictions of the postcentral gyrus were possible in all 10 cases. In all 10 cases, these were in agreement with intraoperative estimation of the precentral gyrus. Functional mapping of somatosensory cortex was achieved noninvasively in surgical patients by using MSI. The accuracy, compared with cortical stimulation, was always sufficient to define motor and somatosensory strips.

Aneurysms of the distal anterior cerebral artery in infants.

Cerebral aneurysms in infants are rare. Of those cases that are reported, only 7 have been identified within the anterior cerebral artery circulation. We report a case of a 7-week-old female who presented with subarachnoid hemorrhage, intracerebral hemorrhage and seizure secondary to a saccular aneurysm of the distal anterior cerebral artery. At surgery, a 1.5-cm thrombosed aneurysm was excised. Postoperatively the child has done well achieving normal milestones at the age of 1 year. We present this case plus a review of the limited number of similar cases found in the literature stressing the presenting signs and symptoms, surgical considerations and outcomes.
