Children’s centres, families and food insecurity in times of crisis

We examine how children's centres in a major city in England responded to food insecurity during the COVID-19 pandemic by helping to run 'FOOD Clubs' to support families. Drawing on data from semi-structured interviews with children's centre staff, we analyse how clubs were organised, why people joined them, and the range of benefits parents derived from them. We extend the literature on food insecurity which focuses heavily on the rise of foodbanks. Our data also informs broader policy debates around supporting parents in poverty, effective early years provision and the challenges facing families experiencing food insecurity.

Analysis of aerosol production and aerosol dispersion during otologic surgery.

BACKGROUND: As a respiratory disease, the transmission of Coronavirus disease (COVID-19) is mainly caused by small droplets and aerosols. Healthcare personnel are particularly exposed during otologic surgery given the continuity with the nasopharynx, where the viral load is high, and the use of high-speed instruments. The purpose of the present study is to test a model of droplet dispersion produced in the performance of a drilling procedure on human bone to provide information about its distribution and size of the deposit in similar conditions to those of an operating theatre, to design different preventive measures. MATERIAL AND METHOD: A mastoidectomy and trans-labyrinthine approach were performed on an embalmed human corpse using for irrigation during drilling methylene blue dye in physiological saline solution (pss) at a concentration of 0.324 mg/mL. The distribution of the drops was stablished using semi-absorbent papers of size 52 cm × 42 cm covering the area around the dissection field to a radius of 150 cm and on the corpse at different heights to check vertical dispersion. The collected deposit material was analysed with the microscope at different magnification objectives. RESULTS: Droplets between 2 µm and 2.6 cm were obtained. The visualization of the coloured droplets in the horizontal plane at a magnification of 1.5 was detected at 150 cm from the focus of emission of milling particles. DISCUSSION: According to our study, bone drilling with high speed motors under continuous saline irrigation in a haemorrhagic surgical field increases the amount of aerosols exposing healthcare personnel to additional airbone particles. This risk does not end in the operating rooms as particles smaller than 2 µm can be suspended in the air for hours and could exit the operating theatre due to the use of positive pressure systems. Thus, the use of N95, FFP2, FFP3 or PAPRS should be considered and the development of hood systems to prevent the dispersion of aerosols during these procedures should be considered.

Cold comfort: Covid-19, lockdown and the coping strategies of fuel poor households

The number of households experiencing fuel poverty is thought to have risen by at least 600,000 in the UK because of the ongoing Covid-19 pandemic. The concentration of fuel poor households in poor quality, energy inefficient accommodation that they have little power to improve means they are particularly negatively affected by the retreat into the home brought about by successive lockdowns and restrictions. For many such households, the home is not the place of sanctuary that it needs to be at a time like this. However, our empirical research into the lived experiences of fuel poverty reveals additional consequences for fuel poor households, chiefly associated with restricted access to third spaces and other disruptions to their usual coping strategies. Based on our evidence, we highlight three key considerations for policy on fuel poverty in the era of Covid-19: the need to rapidly upgrade the energy performance of the existing housing stock;the need to address the additional financial hardship faced by fuel poor households;and the need to prioritise access to third spaces and high-quality public spaces while restrictions last. This paper develops the concept of energy poverty by considering the role of spaces outside the home as part of the overall experience of energy poverty and the range of ways in which policy makers can mitigate its impacts.

Emergency Tracheal Intubation in Patients with COVID-19: A Single-center, Retrospective Cohort Study.

INTRODUCTION: The objective of this study was to compare airway management technique, performance, and peri-intubation complications during the novel coronavirus pandemic (COVID-19) using a single-center cohort of patients requiring emergent intubation. METHODS: We retrospectively collected data on non-operating room (OR) intubations from February 1-April 23, 2020. All patients undergoing emergency intubation outside the OR were eligible for inclusion. Data were entered using an airway procedure note integrated within the electronic health record. Variables included level of training and specialty of the laryngoscopist, the patient's indication for intubation, methods of intubation, induction and paralytic agents, grade of view, use of video laryngoscopy, number of attempts, and adverse events. We performed a descriptive analysis comparing intubations with an available positive COVID-19 test result with cases that had either a negative or unavailable test result. RESULTS: We obtained 406 independent procedure notes filed between February 1-April 23, 2020, and of these, 123 cases had a positive COVID-19 test result. Residents performed fewer tracheal intubations in COVID-19 cases when compared to nurse anesthetists (26.0% vs 37.4%). Video laryngoscopy was used significantly more in COVID-19 cases (91.1% vs 56.8%). No difference in first-pass success was observed between COVID-19 positive cases and controls (89.4% vs. 89.0%, p = 1.0). An increased rate of oxygen desaturation was observed in COVID-19 cases (20.3% vs. 9.9%) while there was no difference in the rate of other recorded complications and first-pass success. DISCUSSION: An average twofold increase in the rate of tracheal intubation was observed after March 24, 2020, corresponding with an influx of COVID-19 positive cases. We observed adherence to society guidelines regarding performance of tracheal intubation by an expert laryngoscopist and the use of video laryngoscopy.

Air Medical Transport of Patients Diagnosed With Confirmed Coronavirus Disease 2019 Infection Undergoing Extracorporeal Membrane Oxygenation: A Case Review and Lessons Learned.

The coronavirus disease 2019 pandemic disrupted health care delivery in every respect, including critical care resources and the transport of patients requiring extracorporeal membrane oxygenation. Innovative solutions allowing for safe helicopter air transport of these critical patients is needed because extracorporeal membrane oxygenation resources are only available in specialty centers. We present a case demonstrating the interfacility collaboration of care for a patient with coronavirus disease 2019 infection and the lessons learned from the air transport. Careful planning, coordination, communication, and teamwork contributed to the safe transport of this patient and several others subsequently.

Toxicity of chloroquine and hydroxychloroquine following therapeutic use or overdose.

INTRODUCTION: While chloroquine, a derivative of quinine, has been used as an antimalarial for 70 years, hydroxychloroquine is now used to treat conditions such as rheumatoid arthritis and systemic lupus erythematosus. In 2020, hydroxychloroquine (and to a lesser extent chloroquine) also received attention as a possible treatment for severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). During investigation for treating coronavirus disease 2019 (COVID-19) caused by SARS-CoV-2, concerns for serious adverse events arose. OBJECTIVE: We review the toxicity associated with hydroxychloroquine and chloroquine use both short-term and long-term and in overdose. METHODS: Medline (via OVID) was searched from its inception through June 7 2020 using the following as either MeSH or keyword terms: ("Chloroquine/" or "Hydroxychloroquine/") AND ("Adverse Drug Event/" or "Toxicities, Drug/" or "Toxic.mp." or "Toxicity.mp." or "Overdose.mp."). We limited resultant articles to those published in English and reporting on Human subjects. This search yielded 330 articles, of which 57 were included. Articles were excluded due to lack of relevance, not reporting desired outcomes, or being duplicative in their content. Twenty-five additional articles were identified through screening references of included articles. To identify toxicities in individuals treated with hydroxychloroquine or chloroquine with COVID-19, we searched PubMed on June 10th, 2020: ("Chloroquine" or "Hydroxychloroquine") AND ("Coronavirus" or "COVID-19" or "SARS-CoV-2"). This search resulted in 638 articles. We reviewed articles for reporting of adverse events or toxicities. Most citations were excluded because they did not include original investigations or extrapolated data from subjects that did not have COVID-19; 34 citations were relevant. For the drug-interactions section, relevant classes and agents were identified through a screen of the https://www.covid19-druginteractions.org/ website. We then conducted targeted searches of PubMed up to June 7th 2020 combining "chloroquine" and "hydroxychloroquine" with terms for specific drug classes and drugs identified from the drug-interaction site as potentially relevant. We found 29 relevant articles. TOXICITY WITH SHORT-TERM USE: Gastrointestinal: Gastrointestinal toxicities are the most common to occur following initiation of chloroquine or hydroxychloroquine. Nausea, vomiting, and diarrhea account for most reported intolerances. Glucose abnormalities: Alterations in blood glucose concentrations may occur with hydroxychloroquine but are rare with standard therapeutic use. Cardiotoxicity: Short-term use can produce conduction abnormalities. Evidence from COVID-19 treatment suggests QT/QTc prolongation is of concern, particularly when used in combination with azithromycin, although disagreement exists across studies. Dermatologic: Drug eruptions or rashes, followed by cutaneous hyperpigmentation, pruritis, Stevens-Johnson syndrome, and toxic epidermal necrolysis, may occur within days to weeks of exposure but usually resolve with the discontinuation of therapy. Neuropsychiatric: Reported symptoms include confusion, disorientation, and hallucination within 24-48 h of drug initiation. Other toxicities: Hemolysis and anemia may occur in patients with glucose-6-phosphate dehydrogenase. Chloroquine treatment of COVID-19 was associated with elevation in creatine kinase and creatine kinase-MB activities with more events in the higher-dose group. TOXICITY WITH LONG-TERM USE: Retinopathy: Retinopathy is the major dose-limiting toxicity associated with long-term use; the risk is higher with increasing age, dose, and duration of usage. Cardiotoxicity: Long-term use has been associated with conduction abnormalities, cardiomyopathy, and valvular disorders. Neurotoxicity: Rarely myositis and muscle weakness, extremity weakness, and pseudoparkinsonism have been reported. TOXICITY IN OVERDOSE: Symptoms in overdose manifest rapidly (minutes to hours) and cardiotoxicity such as cardiovascular shock and collapse are most prominent. Neurotoxic effects such as psychosis and seizure may also occur. CONCLUSIONS: Hydroxychloroquine is a generally well-tolerated medication. Short-term (days to weeks) toxicity includes gastrointestinal effects and rarely glucose abnormalities, dermatologic reactions, and neuropsychiatric events. Cardiotoxicity became of increased concern with its use in COVID-19 patients. Long-term (years) toxicities include retinopathy, neuromyotoxicity, and cardiotoxicity (conduction abnormalities, cardiomyopathy). Deaths from overdoses most often result from cardiovascular collapse.

Point-of-care Lung Ultrasound Is More Sensitive than Chest Radiograph for Evaluation of COVID-19.

INTRODUCTION: Current recommendations for diagnostic imaging for moderately to severely ill patients with suspected coronavirus disease 2019 (COVID-19) include chest radiograph (CXR). Our primary objective was to determine whether lung ultrasound (LUS) B-lines, when excluding patients with alternative etiologies for B-lines, are more sensitive for the associated diagnosis of COVID-19 than CXR. METHODS: This was a retrospective cohort study of all patients who presented to a single, academic emergency department in the United States between March 20 and April 6, 2020, and received LUS, CXR, and viral testing for COVID-19 as part of their diagnostic evaluation. The primary objective was to estimate the test characteristics of both LUS B-lines and CXR for the associated diagnosis of COVID-19. Our secondary objective was to evaluate the proportion of patients with COVID-19 that have secondary LUS findings of pleural abnormalities and subpleural consolidations. RESULTS: We identified 43 patients who underwent both LUS and CXR and were tested for COVID-19. Of these, 27/43 (63%) tested positive. LUS was more sensitive (88.9%, 95% confidence interval (CI), 71.1-97.0) for the associated diagnosis of COVID-19 than CXR (51.9%, 95% CI, 34.0-69.3; p = 0.013). LUS and CXR specificity were 56.3% (95% CI, 33.2-76.9) and 75.0% (95% CI, 50.0-90.3), respectively (p = 0.453). Secondary LUS findings of patients with COVID-19 demonstrated 21/27 (77.8%) had pleural abnormalities and 10/27 (37%) had subpleural consolidations. CONCLUSION: Among patients who underwent LUS and CXR, LUS was found to have a higher sensitivity than CXR for the evaluation of COVID-19. This data could have important implications as an aid in the diagnostic evaluation of COVID-19, particularly where viral testing is not available or restricted. If generalizable, future directions would include defining how to incorporate LUS into clinical management and its role in screening lower-risk populations.

Myth Busters: Dietary Supplements and COVID-19.

News and social media platforms have implicated dietary supplements in the treatment and prevention of coronavirus disease 2019 (COVID-19). During this pandemic when information quickly evolves in the presence of contradicting messages and misinformation, the role of the pharmacist is essential. Here, we review theoretical mechanisms and evidence related to efficacy and safety of select supplements in the setting of COVID-19, including vitamin C, vitamin D, zinc, elderberry, and silver. Evidence evaluating these supplements in COVID-19 patients is lacking, and providers and patients should not rely on dietary supplements to prevent or treat COVID-19. Rather, reference to evidence-based guidelines should guide treatment decisions.
