Postpartum multi-vessel spontaneous coronary artery dissection in the setting of cocaine and amphetamine use: a case report
Authors: McGovern Laurna , Coughlan J J , Murphy Ross , Edroos Sadat 
Published: December 2020

Abstract

Background
Spontaneous coronary artery dissection (SCAD) is a recognized cause of acute coronary syndrome (ACS). Pregnancy, the postpartum period, and illicit drug use have all been reported as potential triggers.

Case summary
We describe the case of a 41-year-old patient who presented to the emergency department with chest pain in the setting of recent cocaine and amphetamine use. The patient was 4 months postpartum following an uncomplicated pregnancy. Past medical history was non-contributory, with no known risk factors for ischaemic heart disease. Electrocardiogram was normal but high-sensitivity troponin T was significantly elevated. Coronary angiography revealed multi-vessel SCAD. This was managed conservatively as the patient remained clinically stable and pain free without high-risk anatomy (left main stem or proximal two-vessel coronary artery dissection).

Discussion
Spontaneous coronary artery dissection must be considered in a postpartum patient presenting with ACS, particularly in the context of environmental stressors such as illicit drug use. Coronary angiography is key to determine diagnosis and guide management. Conservative therapy is favoured, except for patients with ongoing ischaemia, haemodynamic instability, and left main stem involvement. In this case, we suspect SCAD occurred due to the haemodynamic effects of cocaine and amphetamines in the context of structural arterial changes of the postpartum state.
Stroke and bleeding risk stratification in atrial fibrillation: a critical appraisal
Authors: Lane Deirdre A , Lip Gregory Y H 
Published: December 2020

Abstract
Atrial fibrillation (AF) significantly increases the risk of stroke and, therefore, stroke prevention is an essential component of the management for patients with AF. This requires formal assessment of the individual risk of stroke to determine if the patient is eligible for oral anticoagulation (OAC), and if so, their risk of bleeding on OAC, before a treatment decision regarding stroke prevention is made. Risk of stroke is not homogenous; it depends on the presence or absence of risk factors. A plethora of stroke and bleeding risk factors has been identified, including common and less-well established clinical risk factors, plus imaging, urine, and blood biomarkers. Consequently, there are several stroke and bleeding risk stratification scores available and this article provides an overview of them, the risk factors included and how they are scored, and provides a critical appraisal of them. The review also discusses the debate regarding whether female sex is a risk factor or a risk modifier, and highlights the dynamic nature of both stroke and bleeding risk and the need to re-assess these risks periodically to ensure treatment is optimal to reduce the risk of adverse outcomes. This review also summarizes the recommended stroke and bleeding risk stratification scores from all current major international guidelines.
What do we do about atrial high rate episodes?
Authors: Boriani Giuseppe , Vitolo Marco , Imberti Jacopo Francesco , Potpara Tatjana S , Lip Gregory Y H 
Published: December 2020

Abstract
Atrial high rate episodes (AHREs) are defined as asymptomatic atrial tachyarrhythmias detected by cardiac implantable electronic devices with atrial sensing, providing automated continuous monitoring and tracings storage, occurring in subjects with no previous clinical atrial fibrillation (AF) and with no AF detected at conventional electrocardiogram recordings. AHREs are associated with an increased thrombo-embolic risk, which is not negligible, although lower than that of clinical AF. The thrombo-embolic risk increases with increasing burden of AHREs, and moreover, AHREs burden shows a dynamic pattern, with tendency to progression along with time, with potential transition to clinical AF. The clinical management of AHREs, in particular with regard to prophylactic treatment with oral anticoagulants (OACs), remains uncertain and heterogeneous. At present, in patients with confirmed AHREs, as a result of device tracing analysis, an integrated, individual and clinically-guided assessment should be applied, taking into account the patients’ risk of stroke (to be reassessed regularly) and the AHREs burden. The use of OACs, preferentially non-vitamin K antagonists OACs, may be justified in selected patients, such as those with longer AHREs durations (in the range of several hours or ≥24 h), with no doubts on AF diagnosis after device tracing analysis and with an estimated high/very high individual risk of stroke, accounting for the anticipated net clinical benefit, and informed patient’s preferences. Two randomized clinical trials on this topic are currently ongoing and are likely to better define the role of anticoagulant therapy in patients with AHREs.
Incidence and real-world burden of brain metastases from solid tumors and hematologic malignancies in Ontario: a population-based study
Authors: Habbous Steven , Forster Katharina , Darling Gail , Jerzak Katarzyna , Holloway Claire M B , Sahgal Arjun , Das Sunit 
Published: December 2020

Abstract

Background
Although intracranial metastatic disease (IMD) is a frequent complication of cancer, most cancer registries do not capture these cases. Consequently, a data-gap exists, which thwarts system-level quality improvement efforts. The purpose of this investigation was to determine the real-world burden of IMD.

Methods
Patients diagnosed with a non-CNS cancer between 2010 and 2018 were identified from the Ontario Cancer Registry. IMD was identified by scanning hospital administrative databases for cranial irradiation or coding for a secondary brain malignancy (ICD-10 code C793).

Results
25,478 of 601,678 (4.2%) patients with a diagnosis of primary cancer were found to have IMD. The median time from primary cancer diagnosis to IMD was 5.2 (0.7, 15.4) months and varied across disease sites, for example, 2.1 months for lung, 7.3 months for kidney, and 22.8 months for breast. Median survival following diagnosis with IMD was 3.7 months. Lung cancer accounted for 60% of all brain metastases, followed by breast cancer (11%) and melanoma (6%). More advanced stage at diagnosis and younger age were associated with a higher likelihood of developing IMD (P &lt; .0001). IMD was also associated with triple-negative breast cancers and ductal histology (P &lt; .001), and with small-cell histology in patients with lung cancer (P &lt; .0001). The annual incidence of IMD was 3,520, translating to 24.2 per 100,000 persons.

Conclusion
IMD represents a significant burden in patients with systemic cancers and is a significant cause of cancer mortality. Our findings support measures to actively capture incidents of brain metastasis in cancer registries.

Published: December 2020

Abstract

Background
We aimed to characterise the genetic determinants and context of two meropenem-resistant clinical isolates of Acinetobacter baumannii isolated from children hospitalised with bloodstream infections in Dar es Salaam, Tanzania.

Methods
Antimicrobial susceptibility was determined by disc diffusion E-test and broth microdilution. Genomes were completed using a hybrid assembly of Illumina and Oxford Nanopore Technologies sequencing reads and characterisation of the genetic context of resistance genes, multi-locus sequence types (STs) and phylogenetic analysis was determined bioinformatically.

Results
Twelve A. baumannii were isolated from 2226 blood cultures, two of which were meropenem-resistant. The two meropenem-resistant isolates, belonging to distinct STs, ST374 and ST239, were found to harbour blaNDM-1, which was chromosomally located in isolate DT0544 and plasmid-located in isolate DT01139. The genetic environment of blaNDM-1 shows the association of insertion sequence ISAba125 with blaNDM-1 in both isolates. Both isolates also harboured genes conferring resistance to other β-lactams, aminoglycosides and cotrimoxazole.

Conclusions
This is the first report of New Delhi metallo-β-lactamase-producing isolates of A. baumannii from Tanzania. The genetic context of blaNDM-1 provides further evidence of the importance of ISAba125 in the spread of blaNDM-1 in A. baumannii. Local surveillance should be strengthened to keep clinicians updated on the incidence of these and other multidrug-resistant and difficult-to-treat bacteria.
Efficacy and safety of montelukast sodium combined with fluticasone in the treatment of adult bronchial asthma
Authors: Luo Huiling , Han Hongmei , Liu Xiaoli , Liu Qin 
Published: December 2020

Abstract

Background:
Bronchial asthma (BA) is a chronic airway inflammatory disease with reversible airflow limitation as the main clinical manifestations, such as wheezing, cough, shortness of breath, chest tightness, etc, mediated by a variety of inflammatory cells, which can be recurrent. Clinical can improve symptoms, but cannot be cured; glucocorticoid is the most important first-line medication. Clinical practice has shown that montelukast sodium combined with fluticasone in the treatment of adult BA can improve clinical efficacy and reduce adverse reactions. The purpose of this study is to systematically study the efficacy and safety of montelukast sodium combined with fluticasone in the treatment of adult BA.

Methods:
The Chinese databases (CNKI, VIP, Wanfang, Chinese Biomedical Database) and English databases (PubMed, the Cochrane Library, Embase, Web of Science) were searched by computer, for the randomized controlled clinical studies of montelukast sodium combined with fluticasone in the treatment of adult BA from establishment of database to October 2020. Two researchers independently extracted the relevant data and evaluated the quality of the literatures, and used RevMan5.3 software to conduct meta-analyze of the included literatures.

Results:
This study assessed the efficacy and safety of montelukast sodium combined with fluticasone in the treatment of adult BA through total effective rate, pulmonary function (FEV1, FVC, PEF, FEV1/FVC), and adverse reactions.

Conclusion:
This study will provide reliable evidence-based evidence for the clinical application of montelukast sodium combined with fluticasone in the treatment of adult BA.

A mobile delivered self-exercise program for female farmers
Authors: Baek Sora , Kim Gowun , Park Hee-won 
Published: December 2020

Abstract

Introduction:
Female farmers commonly experience musculoskeletal pain in the back, knee, and shoulder. Despite their obvious advantages in reducing musculoskeletal pain, face-to-face exercise programs are limited by geographical and physical barriers. Thus, we decided to introduce eHealth technology to farmers’ musculoskeletal health care. Using a mobile application (app), we aim to provide a tailored self-exercise program for shoulder, knee, and back pain in female farmers in rural areas after a musculoskeletal health check-up.

Methods:
This study is planned as 2 randomized control studies (MObile Delivered self-Exercise [MODE] phase I and phase II). We plan to recruit 200 female farmers aged 41 to 70 years. Initially, the shoulders, knees, and low back will be evaluated to provide individualized exercise programs. In MODE-I (single-blinded: evaluator), the subjects will be randomly allocated to experimental (n = 100) and control (n = 100) groups using a computer-generated sequence. Both groups will perform a 3-month self-exercise using a smartphone app or physical education data (booklets), respectively. Outcomes including exercise completion will be assessed at 3 months. In MODE-II, after subject random allocation, the experimental and control groups will perform exercise using a smartphone app with and without real-time feedback, respectively. Every 3 months, the level of the exercise program will be evaluated and the difficulty level will be adapted accordingly. After MODE-II is completed, all subjects will undergo close-out assessment.

Discussion:
This will be the first attempt to compare methods using booklets and apps to identify effective ways of providing personalized self-exercise programs according to musculoskeletal health stages by evaluating female farmers (MODE-I). This will help clarify whether the mobile app is effective for self-exercise compared to a conventional booklet. The MODE-II study will help to assess the effect of providing feedback through the mobile app. Finally, we will evaluate musculoskeletal health according to the degree of participation over 12 months to confirm the effect of self-exercise. Our study should aid in managing musculoskeletal health for farmers living in rural areas and help promote health in the “untact” era.

Published: December 2020

Abstract
This study aimed to investigate the effects of age on the peak ratio (PR) of ophthalmic artery (OA) Doppler.
The initial peak velocity (P1), second peak velocity (P2) and PR of OA were detected by color Doppler ultrasonography in 147 healthy subjects. All of the subjects were divided into 6 groups (G1-G6) according to the age. (G1, 20-29 years; G2, 30-39 years; G3, 40-49 years; G4, 50-59 years; G5, 60-69 years; and G6, 70 years or older). The blood pressure and heart rate were also examined before ultrasonography. The influences of age, blood pressure and heart rate on the P1, P2, and PR were further evaluated.
There were significant differences in the P2 and PR among different age groups except for P1. There were no significant differences in the P2 and PR between the first 2 groups, neither among the latter 4 groups. Nevertheless, P2 and PR in the first 2 groups were significantly different from those in the latter 4 groups. In addition, both P2 and PR (not P1) increased significantly with age, systolic and diastolic blood pressure. P1, P2 and PR were not related to heart rate. Both P2 and PR were closely related to the age. PR also had a weak relationship with systolic blood pressure.
Both P2 and PR of OA Doppler increase with age. Concern should be raised when P2 and PR are used to evaluate the hemodynamic change of OA.

Primary care pathway- a novel way to reduce the burden on orthopaedic fracture clinics within the pediatric subgroup
Authors: Bussoletti Timothy , Quach Lucian , Fuschini Christian , Khire Pushkar , Cleary Aidan 
Published: December 2020

Abstract
Emergency departments receive an increasing amount of musculoskeletal injuries, with the majority referred to a fracture clinic (FCs). A literature review revealed certain orthopaedic injuries can be safely managed away from the FC pathway by general practitioners (GPs) or allied health professionals (AHPs). The present study aims to review all paediatric presentations to FCs at 2 Queensland hospitals, identifying low risk injuries that could potentially be managed by GPs or AHPs. This study is a continuation from Cleary et al in which a primary care pathway (PCP) was proposed for the management of low risk adult orthopaedic injuries. A PCP has the potential to have significant savings to the health system.
A retrospective study was conducted looking at paediatric patients (<16 years) referrals to 2 FCs over 8 weeks. Injuries were categorised into those requiring FC care supervised by an orthopaedic surgeon, and those that can be safely managed by GPs or AHPs via a PCP.
Four hundred ninety (57.7%) of the 849 patients referred to FC were assessed as suitable for PCP care. The most common upper limb injury deemed suitable was radius and ulna buckle fractures (18.4%), while the most common lower limb injury is ankle sprains (8%). Total failure to attend rate in the PCP group was 6.7%.
Adopting the PCP has the potential to significantly reduce FC referrals. With proven success of similar pathways abroad, the PCP may generate significant time and financial savings for both the health care system and patient.

Published: December 2020

Abstract

Background:
Lesional and symptomatic causes of epilepsy are the most common neurological disorders of the brain. Topiramate effectively controls newly diagnosed epilepsy and refractory focal seizures, but high-dose topiramate does not improve seizure control. This study aimed to evaluate the clinical efficacy and safety of dose-escalated topiramate as first-line monotherapy and add-on therapy in patients with neurosurgery-related epilepsy.

Material and Methods:
A total of 55 neurosurgical patients with epilepsy were divided into monotherapy and add-on therapy groups and both groups received topiramate via the dose-escalation method. The primary efficacy outcomes were seizure-free rate and seizure response rate. Adverse events and seizure frequency were recorded.

Results:
The seizure response rate in the first month of monotherapy was significantly better than that of add-on therapy (89% vs 65%, P < .05), but no significant differences were found in seizure response rates between the 2 groups after 2 months of treatment. Both monotherapy and add-on therapy were effective in controlling seizures, with mean seizure frequency of 0.725 vs 0.536 and seizure-free rate of 88% vs 78.6%. Both treatments showed good improvement of seizure frequency in patients without tumor. The efficacy of monotherapy was better than that of add-on therapy (80% vs 29.2%) in patients with body mass index (BMI) ≤24. However, add-on therapy was better than monotherapy (76.7% vs 21.4%) in patients with BMI > 24. Dizziness (25.5%) and headache (16.4%) were the most common adverse events. No severe adverse event such as cognitive impairment was observed.

Conclusions:
Dose-escalated topiramate monotherapy and add-on therapy demonstrate good efficacy and safety, with fewer adverse events in seizure control in neurosurgical patients.
Incidence of nontuberculous mycobacterial disease and coinfection with tuberculosis in a tuberculosis-endemic region

Abstract
Nontuberculous mycobacteria (NTM) infection may interfere in the diagnosis and treatment of tuberculosis (TB) in TB-endemic regions. However, the population-based incidence of NTM disease and NTM–TB coinfection remains unclear.
We used Taiwan's National Health Insurance Research Database to identify new diagnoses of NTM disease and TB from 2005 to 2013 and calculated the incidence rate and the proportion of NTM–TB coinfection. The patients with NTM disease or TB were determined by the use of disease codes from International Classification of Diseases, Ninth Revision, Clinical Modification, laboratory mycobacterium examination codes, and antimycobacterial therapy receipts.
From 2005 to 2013, the age-adjusted incidence rate of NTM disease increased from 5.3 to 14.8 per 100,000 people per year and the age-adjusted incidence rate of NTM–TB coinfection was around 1.2 to 2.2 per 100,000 people per year. The proportion of NTM–TB coinfection among patients with confirmed TB was 2.8%. Male and older patients had a significantly higher incidence of NTM disease. The effects of urbanization and socioeconomic status (SES) on the incidences of TB and NTM disease were different. Rural living and lower SES were significantly associated with increasing the incidence of confirmed TB but not with that of NTM disease. For NTM disease, those living in the least urbanized area had significantly lower incidence rate ratio than in the highest urbanized area. The incidence of NTM–TB coinfection was higher in older patients and compared with patients aged < 45 years, the incidence rate ratio of the patients aged> 74 years was 12.5.
In TB-endemic Taiwan, the incidence of NTM disease increased from 2005 to 2013. Male gender and old age were risk factors for high incidence of NTM disease. SES did not have a significant effect on the incidence of NTM disease, but rural living was associated with lower incidence of NTM disease. In TB-endemic areas, NTM–TB coinfection could disturb the diagnosis of TB and treatment, especially in elderly patients.
