Streptococcal pharyngitis, which commonly occurs in children, should be treated with antibiotics. Clinical prediction rules to differentiate streptococcal pharyngitis from viral infection are not recommended in children. Rapid point-of-care (POC) antigen tests have limited sensitivity and so are not often used in Canadian paediatric emergency departments (EDs). Standard paediatric practice is to rely on laboratory-based testing, which often results in a delay before the results can be communicated to the patient; this may impede appropriate prescribing, decrease caregiver satisfaction and delay recovery. The objective of this study is to determine whether a novel rapid molecular POC assay for streptococcal pharyngitis leads to more appropriate antibiotic use in children seeking care in a paediatric ED than standard laboratory-based testing.
A randomised, superiority, open-label, trial with two parallel groups. see more Children presenting to a tertiary paediatric ED at least 3 years of age who have a throat swab ordered for diagnosis of streptococcal pharyngitis will be eligible; those who have taken antibiotics within 72 hours prior to presentation and those with additional active infections will be excluded. link2 The primary study outcome will be appropriate antibiotic treatment at 3-5 days postenrolment. Secondary outcomes include time to symptom resolution, caregiver satisfaction, caregiver/child absenteeism, number of subsequent healthcare visits, clinician satisfaction and incremental cost-effectiveness of POC testing. A total of 352 participants will be needed.
All study documentation has been approved by the Hamilton Integrated Research Ethics board and informed consent will be obtained from all participants. Data from this trial will be presented at major conferences and published in peer-reviewed publications to facilitate collaborations with networks of clinicians experienced in the dissemination of clinical guidelines.

People with HIV have high levels of multimorbidity, but studies often focus on high-risk comorbidities such as hypertension or coronary artery disease. We examined both high-risk and functional comorbidities in an ethnically diverse clinic population to compare the prevalence of comorbidities and different patterns of multimorbidity.
Retrospective cross-sectional study.
University-based primary care HIV clinic with two locations in New York City.
Patients who had been seen by a physician at least once between 1 June 2016 and 31 May 2017.
Data regarding demographics, diagnoses and lab values were downloaded in a one-time data import from the electronic medical record. Comorbidities were classified as high-risk (with major impact on mortality) or functional (with major impact on function), and multimorbidity was determined for both classes in the total sample of 2751. Factors associated with high-risk and functional multimorbidity were determined first through bivariate analysis and then through multi on mortality and should be assessed and monitored, especially as the population with HIV ages.
Mechanical ventilatory is a crucial element of acute brain injured patients' management. The ventilatory goals to ensure lung protection during acute respiratory failure may not be adequate in case of concomitant brain injury. Therefore, there are limited data from which physicians can draw conclusions regarding optimal ventilator management in this setting.
This is an international multicentre prospective observational cohort study. The aim of the 'multicentre observational study on practice of ventilation in brain injured patients'-the VENTIBRAIN study-is to describe the current practice of ventilator settings and mechanical ventilation in acute brain injured patients. Secondary objectives include the description of ventilator settings among different countries, and their association with outcomes. Inclusion criteria will be adult patients admitted to the intensive care unit (ICU) with a diagnosis of traumatic brain injury or cerebrovascular diseases (intracranial haemorrhage, subarachnoid haemorrhage, ischaemic stroke), requiring intubation and mechanical ventilation and admission to the ICU. Exclusion criteria will be the following patients aged <18 years; pregnant patients; patients not intubated or not mechanically ventilated or receiving only non-invasive ventilation. Data related to clinical examination, neuromonitoring if available, ventilator settings and arterial blood gases will be recorded at admission and daily for the first 7 days and then at day 10 and 14. link3 The Glasgow Outcome Scale Extended on mortality and neurological outcome will be collected at discharge from ICU, hospital and at 6 months follow-up.
The study has been approved by the Ethic committee of Brianza at the Azienda Socio Sanitaria Territoriale-Monza. Data will be disseminated to the scientific community by abstracts submitted to the European Society of Intensive Care Medicine annual conference and by original articles submitted to peer-reviewed journals.

Our main objective is to estimate the trend of deaths by COVID-19 on a global scale, considering the six continents.
The study design was a retrospective observational study conducted using the secondary data provided by the Our World in Data project on a public domain.
This study was conducted based on worldwide deaths by COVID-19 recorded for the Our World in Data project from 29 February 2020 to 17 February 2021.
Estimating the trend in COVID-19 deaths is not a trivial task due to the problems associated with the COVID-19 data, such as the spatial and temporal heterogeneity, observed seasonality and the delay between the onset of symptoms and diagnosis, indicating a relevant measurement error problem and changing the series' dependency structure. To bypass the aforementioned problems, we propose a method to estimate the components of trend, seasonality and cycle in COVID-19 data, controlling for the presence of measurement error and considering the spatial heterogeneity. We used the proposed model accurate to estimate the general patterns of the occurrence of deaths related to COVID-19.
To evaluate the diagnostic capability of optical coherence tomography (OCT) in children aged under 18 years old with intracranial hypertension (IH).
Systematic review.
We conducted a systematic review using the following platforms to search the keywords 'optical coherence tomography' and 'intracranial hypertension' from inception to 2 April 2020 Cochrane Central Register of Controlled Trials, EMBASE, MEDLINE, PubMed and Web of Science, without language restrictions. Our search returned 2729 records, screened by two independent screeners. Studies were graded according to the Oxford Centre for Evidence-Based Medicine and National Institutes of Health Quality Assessment Tool for observational studies.
Twenty-one studies were included. Conditions included craniosynostosis (n=354 patients), idiopathic IH (IIH; n=102), space-occupying lesion (SOL; n=42) and other pathology (n=29). OCT measures included optic nerve parameters, rim parameters (notably retinal nerve fibre layer thickness) and retinal parameters. Levels of evidence included 2b (n=13 studies), 3b (n=4) and 4 (n=4). Quality of 10 studies was fair and 11 poor. There was inconsistency in OCT parameters and reference measures studied, although OCT did demonstrate good diagnostic capability for IH in craniosynostosis, IIH and SOL.
This systematic review identified various studies involving OCT to assist diagnosis and management of IH in children with craniosynostosis, IIH, SOL and other pathology, in conjunction with established clinical measures of intracranial pressure. However, no level 1 evidence was identified. Validating prospective studies are, therefore, required to determine optimal OCT parameters in this role and to develop formal clinical guidelines.

Hands play a part in the transmission of infections. Handwashing with soap sufficiently reduces the level of hand contamination and the spread of infections. As soap is not usually available due to cost, ash is often used as a zero-cost alternative to soap in the rural settings of developing countries. However, there is limited evidence on the effectiveness of ash to reduce microbial contamination of hands. This study is, therefore, designed to assess the effect of ash on microbial contamination of hands in the rural settings of northwest Ethiopia.
A two-arm clustered-randomised controlled trial will be employed. A total of 11 clusters per arm will be selected using simple random sampling technique. A total of 220 mothers or caregivers of under-5 children will be included in each arm. After providing health education on effective handwashing process, we will ask study subjects to do the usual activities. We will then take swab samples from the dominant hand before washing. After swabbing, participants will be asked to wash their hands with water only and with ash by following effective handwashing procedures. We will again take swab samples from the dominant hand after washing and drying. Finally, we will compare each intervention arm against the control. A generalised estimating equation (GEE) with robust SE estimation will be used to account the cluster nature of data.
Results will be published in peer-reviewed journal and presented at international conferences. The protocol is approved by the Institutional Review Board of the University of Gondar, Ethiopia.

This study aimed to assess the possible relationship between television viewing and overweight and obesity among Timorese women of reproductive age.
This cross-sectional study analysed the Timor-Leste Demographic and Health Survey 2016 dataset. A weighted sample of 11 398 Timorese women aged 15-49 years was chosen using a two-stage stratified random sampling technique. Asian criteria-based body mass index (BMI) cut-offs were used to define overweight (BMI 23.0 to <27.5 kg/m
) and obesity (BMI ≥27.5 kg/m
). Frequency of TV viewing was categorised into three groups (1) not at all, (2) less than once a week and (3) at least once a week. Multilevel ordered logistic regression was performed to identify the correlates of overweight and obesity. Both crude and adjusted odds ratios (AOR) along with a 95% CI were calculated to show the strength of association.
Among 11 398 respondents, 19.4% were overweight or obese (overweight 15.7% and obese 3.8%). Although about half of the respondents reportedly did noterns to clarify the possible mechanism through which TV viewing may influence BMI in those groups.
Essential medicines lists have been created and used globally in countries that range from low-income to high-income status. The aim of this paper is to compare the essential medicines list of high-income countries with each other, the WHO's Model List of Essential Medicines and the lists of countries of other income statuses.
High-income countries were defined by World Bank classification. High-income essential medicines lists were assessed for medicine inclusion and were compared with the subset of high-income countries, the WHO's Model List and 137 national essential medicines lists. Medicine lists were obtained from the Global Essential Medicines database. Countries were subdivided by income status, and the groups' most common medicines were compared. Select medicines and medicine classes were assessed for inclusion among high-income country lists.
The 21 high-income countries identified were most like each other when compared with other lists. They were more like upper middle-income countries and least like low-income countries.
