RESUMEN
Background: There has been an increase in opioid usage and opioid-related deaths. Opioids prescribed to surgical patients have similarly increased. The aim of this study was to assess opioid consumption in patients undergoing laparoscopic appendectomy (LA) and laparoscopic cholecystectomy (LC) and to determine whether a standardized prescription could affect opioid consumption without affecting patient satisfaction. Methods: Patients undergoing LA or LC were recruited prospectively during 2 time periods (April to June 2017 and November 2017 to January 2018). In the first phase, surgeons continued their usual postoperative analgesia prescribing patterns. In the second phase, a standardized prescription was implemented. Patients were contacted by telephone and a questionnaire was completed for both phases of the study. The primary outcome was the quantity of opioids prescribed and consumed. Results: In the first phase, 166 patients who underwent LC or LA were recruited. The median number of prescribed opioid tablets was 20 and the median number consumed was 2. Ninety-five percent of patients reported satisfaction with their analgesia. Based on these results, a standardized prescription for multimodal analgesia was implemented for the second phase, consisting of 10 opioid tablets. In the second phase, 129 patients who underwent LA or LC were recruited. There was a significant decrease in the median number of opioid pills filled (10) and consumed (0), with no difference in reported satisfaction with analgesia. Conclusion: Patients are prescribed an excess of opioids after LA or LC. Implementation of a standardized prescription based on a quality improvement intervention was effective at decreasing the number of opioids prescribed and consumed.
Contexte: On a observé une augmentation de la consommation d'opioïdes, ainsi qu'une hausse des décès associés à ces substances. On a aussi constaté une augmentation semblable dans la prescription d'opioïdes aux patients ayant subi une chirurgie. La présente étude visait à évaluer la consommation d'opioïdes chez les personnes ayant subi une appendicectomie par laparoscopie (AL) ou une cholécystectomie par laparoscopie (CL), de même qu'à déterminer si une ordonnance normalisée pouvait modifier la consommation d'opioïdes sans nuire à la satisfaction des patients. Méthodes: Des patients devant subir une AL ou une CL ont été recrutés de façon prospective entre avril et juin 2017 et entre novembre 2017 et janvier 2018. Durant la première phase de l'étude, les chirurgiens ont maintenu leurs habitudes de prescription d'analgésie postopératoire. Durant la deuxième phase, toutefois, ils devaient avoir recours à une ordonnance normalisée. Dans les 2 phases de l'étude, les patients ont été joints par téléphone et un questionnaire a été rempli. Le principal résultat à l'étude était la quantité d'opioïdes prescrits et consommés. Résultats: Pour la première phase de l'étude, 166 patients ont été recrutés. Les nombres médians de comprimés prescrits et consommés étaient de 20 et de 2, respectivement. De tous les patients, 95 % se sont dits satisfaits de leur analgésie. Pour la deuxième phase, une ordonnance normalisée d'analgésie multimodale, qui comptait 10 comprimés, a été mise en place, et 129 patients ont été recrutés. On a alors observé une diminution significative du nombre médian de comprimés remis (10) et consommés (0), et aucune différence quant au degré de satisfaction déclaré. Conclusion: Les patients se voient prescrire trop d'opioïdes après une AL ou une CL. La création d'une ordonnance normalisée dans le cadre d'une intervention d'amélioration de la qualité a réduit efficacement le nombre de comprimés d'opioïdes prescrits et consommés.

INTRODUCTION: The purpose of this survey was to determine the equipment that anesthesiologists prefer in difficult tracheal intubation and "cannot intubate, cannot ventilate" (CICV) situations. METHODS: A questionnaire was e-mailed to members of the Canadian Anesthesiologists' Society to ascertain their preferences, experience, and comfort level with regard to their use of airway equipment in difficult intubation and CICV situations in adult patients. A Chi square test was used to analyse the data. All reported P values are two-sided. RESULTS: Nine hundred ninety-seven of 2,532 questionnaires (39%) were returned. In an unanticipated difficult direct laryngoscopic intubation situation, 893 of 997 (90%) respondents chose a video laryngoscope as the first-choice rescue technique, while 41 (4%) and 21 (2%) of respondents chose a flexible bronchoscope and an intubating laryngeal mask airway device, respectively. The majority of anesthesiologists had experience and were comfortable with using a flexible bronchoscope or a video laryngoscope. Regarding CICV, 294 of 955 (31%) respondents stated that they had never encountered it. Wire-guided cricothyroidotomy was chosen as the first-choice surgical airway by 375 of 955 (39%) respondents, while intravenous catheter cricothyroidotomy and "defer to tracheostomy by surgeon" were selected by 266 (28%) and 215 (23%) respondents, respectively. Seven hundred eighty-five of 997 (78%) respondents were familiar with the exact steps of the American Society of Anesthesiologists' difficult airway algorithm, while 448 (47%) had attended an airway workshop within the past five years. CONCLUSIONS: In a difficult intubation situation, the most frequently selected first-choice airway device was a video laryngoscope, followed by a flexible bronchoscope. In a CICV situation, the most frequently selected first-choice surgical airway technique was a wire-guided cricothyroidotomy, followed by an intravenous catheter cricothyroidotomy.

BACKGROUND: During the COVID-19 pandemic, the field of infodemic management has grown in response to urgent global need. Social listening is the first step in managing the infodemic, and many organizations and health systems have implemented processes. Social media analysis tools have traditionally been developed for commercial purposes, rather than public health, and little is known of the experiences and needs of those professionals using them for infodemic management. METHODS: We developed a cross sectional survey and distributed through global infodemic management networks between December 2022 and February 2023. Questions were structured over four sections related to work-practice and user needs and did not collect any personal details from participants. Descriptive analysis was conducted on the study results. Qualitative analysis was used to categorise and understand answers to open-text questions. RESULTS: There were 417 participants, 162/417 who completed all survey questions, and 255/417 who completed some, all responses are included in analysis. Respondents came from all global regions and a variety of workplaces. Participants had an average of 4.4 years' experience in the analysis of social media for public health. COVID-19 was the most common health issue people had conducted social media analysis for. Results reveal a range of training, technical capacity, and support needs. CONCLUSIONS: This paper is the first we are aware of to seek and describe the needs of those using social media analysis platforms for public health purposes since the start of the COVID-19 pandemic. There are key areas for future work and research, including addressing the training, capacity building and leadership needs of those working in this space, and the need to facilitate easier access to better platforms for performing social media analysis.
RESUMEN
Each epidemic and pandemic is accompanied by an infodemic. The infodemic during the COVID-19 pandemic was unprecedented. Accessing accurate information was difficult and misinformation harmed the pandemic response, the health of individuals and trust in science, governments and societies. WHO is building a community-centered information platform, the Hive, to deliver on the vision of ensuring that all people everywhere have access to the right information, at the right time, in the right format in order to make decisions to protect their health and the health of others. The platform provides a safe space for knowledge-sharing, discussion, collaboration, and access to credible information. The Hive platform is an innovative minimum viable product that seeks to leverage the complex information ecosystem and the invaluable role of communities to share and access trustworthy health information during epidemics and pandemics.

The COVID-19 pandemic underlined that communities are key in sharing trusted, timely and relevant information especially during a health emergency where the overabundance of information makes it difficult to make decisions to protect one's health. The WHO Hive project grew out of the desire to create a community-centered solution with the potential to change the way credible health information is shared, adapted, understood and used for health-related decision making before, during and after an epidemic or pandemic. The Hive online platform provides a safe space for knowledge-sharing, discussion, and collaboration, including access to timely scientific information through direct engagement with WHO subject matter experts, and the true innovation lies within the platform's ability to leverage the power of communities to crowdsource solutions to community concerns and needs. The platform is equipped with a set of synchronous and asynchronous features and tools to encourage coworking and facilitate cross-sectorial collaboration. The Hive seeks to leverage the expert communities to share resources and knowledge for epidemic and pandemic preparedness and provide an environment that is able to respond to the challenges faced in a complex information ecosystem.

BACKGROUND: Vaccine hesitancy is one of the many factors impeding efforts to control the COVID-19 pandemic. Exacerbated by the COVID-19 infodemic, misinformation has undermined public trust in vaccination, led to greater polarization, and resulted in a high social cost where close social relationships have experienced conflict or disagreements about the public health response. OBJECTIVE: The purpose of this paper is to describe the theory behind the development of a digital behavioral science intervention-The Good Talk!-designed to target vaccine-hesitant individuals through their close contacts (eg, family, friends, and colleagues) and to describe the methodology of a research study to evaluate its efficacy. METHODS: The Good Talk! uses an educational serious game approach to boost the skills and competences of vaccine advocates to have open conversations about COVID-19 with their close contacts who are vaccine hesitant. The game teaches vaccine advocates evidence-based open conversation skills to help them speak with individuals who have opposing points of view or who may ascribe to nonscientifically supported beliefs while retaining trust, identifying common ground, and fostering acceptance and respect of divergent views. The game is currently under development and will be available on the web, free to access for participants worldwide, and accompanied by a promotional campaign to recruit participants through social media channels. This protocol describes the methodology for a randomized controlled trial that will compare participants who play The Good Talk! game with a control group that plays the widely known noneducational game Tetris. The study will evaluate a participant's open conversation skills, self-efficacy, and behavioral intentions to have an open conversation with a vaccine-hesitant individual both before and after game play. RESULTS: Recruitment will commence in early 2023 and will cease once 450 participants complete the study (225 per group). The primary outcome is improvement in open conversation skills. Secondary outcomes are self-efficacy and behavioral intentions to have an open conversation with a vaccine-hesitant individual. Exploratory analyses will examine the effect of the game on implementation intentions as well as potential covariates or subgroup differences based on sociodemographic information or previous experiences with COVID-19 vaccination conversations. CONCLUSIONS: The outcome of the project is to promote more open conversations regarding COVID-19 vaccination. We hope that our approach will encourage more governments and public health experts to engage in their mission to reach their citizens directly with digital health solutions and to consider such interventions as an important tool in infodemic management.

RESUMEN
The COVID-19 infodemic is an overwhelming amount of information that has challenged pandemic communication and epidemic response. WHO has produced weekly infodemic insights reports to identify questions, concerns, information voids expressed and experienced by people online. Publicly available data was collected and categorized to a public health taxonomy to enable thematic analysis. Analysis showed three key periods of narrative volume peaks. Understanding how conversations change over time can help inform future infodemic preparedness and prevention planning.

BACKGROUND: Amid the COVID-19 pandemic, there has been a need for rapid social understanding to inform infodemic management and response. Although social media analysis platforms have traditionally been designed for commercial brands for marketing and sales purposes, they have been underused and adapted for a comprehensive understanding of social dynamics in areas such as public health. Traditional systems have challenges for public health use, and new tools and innovative methods are required. The World Health Organization Early Artificial Intelligence-Supported Response with Social Listening (EARS) platform was developed to overcome some of these challenges. OBJECTIVE: This paper describes the development of the EARS platform, including data sourcing, development, and validation of a machine learning categorization approach, as well as the results from the pilot study. METHODS: Data for EARS are collected daily from web-based conversations in publicly available sources in 9 languages. Public health and social media experts developed a taxonomy to categorize COVID-19 narratives into 5 relevant main categories and 41 subcategories. We developed a semisupervised machine learning algorithm to categorize social media posts into categories and various filters. To validate the results obtained by the machine learning-based approach, we compared it to a search-filter approach, applying Boolean queries with the same amount of information and measured the recall and precision. Hotelling T2 was used to determine the effect of the classification method on the combined variables. RESULTS: The EARS platform was developed, validated, and applied to characterize conversations regarding COVID-19 since December 2020. A total of 215,469,045 social posts were collected for processing from December 2020 to February 2022. The machine learning algorithm outperformed the Boolean search filters method for precision and recall in both English and Spanish languages (P<.001). Demographic and other filters provided useful insights on data, and the gender split of users in the platform was largely consistent with population-level data on social media use. CONCLUSIONS: The EARS platform was developed to address the changing needs of public health analysts during the COVID-19 pandemic. The application of public health taxonomy and artificial intelligence technology to a user-friendly social listening platform, accessible directly by analysts, is a significant step in better enabling understanding of global narratives. The platform was designed for scalability; iterations and new countries and languages have been added. This research has shown that a machine learning approach is more accurate than using only keywords and has the benefit of categorizing and understanding large amounts of digital social data during an infodemic. Further technical developments are needed and planned for continuous improvements, to meet the challenges in the generation of infodemic insights from social media for infodemic managers and public health professionals.
RESUMEN
RATIONALE: The cause of increased pharyngeal collapsibility in patients with obstructive sleep apnea is incompletely understood. In awake healthy subjects, we showed that fluid displacement from the legs into the neck induced by lower body positive pressure reduces upper airway size and increases its collapsibility. Prolonged sitting leads to dependent fluid accumulation in the legs. OBJECTIVES: To test the hypotheses that the apnea-hypopnea index (AHI) during sleep will be related to the amount of fluid spontaneously displaced from the legs overnight, and that this will, in turn, be related to the time spent sitting the previous day. METHODS: In 23 nonobese healthy men referred for sleep studies for suspected obstructive sleep apnea, we assessed the changes in leg fluid volume and in neck circumference from the beginning to the end of the night, and the time spent sitting during the previous day. MEASUREMENTS AND MAIN RESULTS: The overnight change in leg fluid volume correlated strongly with the AHI (r = -0.773, P < 0.001), the change in neck circumference (r = -0.792, P < 0.001), and the time spent sitting (r = -0.588, P = 0.003). Multivariate analysis showed that the only significant independent correlates of the AHI were the overnight changes in leg fluid volume and neck circumference, which together explained 68% of the variability in the AHI among subjects. CONCLUSIONS: These novel findings suggest that overnight rostral fluid displacement from the legs, related to prolonged sitting, may play a previously unrecognized role in the pathogenesis of obstructive sleep apnea in nonobese men that is independent of body weight.

PURPOSE: This study examined the effect of external fibreoptic bronchoscope (FOB) rotations on endotracheal tube (ETT) orientations at the glottic level. METHODS: Using a mannequin, a nasal FOB was inserted for image capture. A second FOB with a preloaded ETT taped to its top was inserted orally into mid-trachea. The FOB with the taped ETT was rotated as a unit in the axial plane to five different external angles (-90°, -45°, 0°, +45°, +90°). At each external rotation, the ETT was advanced into the trachea. The image of the ETT at the glottic level was captured. Endotracheal tube orientation was quantified according to the glottic zone faced by the ETT. The ETT orientations were compared amongst the five external FOB rotations using the Kruskal-Wallis Test, while the ETT orientations at -90°, -45°, +45°, and +90° FOB rotations were compared with 0° rotation using the Mann-Whitney U test. RESULTS: There was a significant difference in the ETT orientations amongst the five FOB rotations (P < 0.001). The ETT orientations at -90°, -45°, +45°, and +90° FOB rotations were different from the 0° rotation (P < 0.001 for all comparisons). A -90° FOB rotation was most effective in turning the ETT tip away from the right laryngeal structures and the interarytenoid tissue. CONCLUSION: With the ETT loaded on a FOB, rotation of the FOB prior to advancing the ETT is effective in changing the ETT orientation at the glottis. A -90° FOB rotation is most effective in turning the ETT tip away from the right laryngeal structures and interarytenoid tissue.

Fluid shift from the legs to the neck induced by LBPP (lower-body positive pressure) increases UA (upper airway) collapsibility in healthy men. Rostral fluid displacement during recumbency may therefore contribute to the pathogenesis of OSA (obstructive sleep apnoea). There is a higher prevalence of OSA in men than in women. We therefore hypothesized that UA collapsibility increases more in men in response to rostral fluid displacement than in women. UA collapsibility was assessed in healthy, non-obese men and women while awake by determining UA Pcrit (critical closing pressure) during application of different suction pressures to the UA. Subjects were randomized to 5 min control or LBPP arms after which they crossed-over into the other arm following a 30 min washout. LBPP was applied by inflating anti-shock trousers wrapped around both legs to 40 mmHg. Pcrit, leg fluid volume and neck circumference were measured at baseline and after 5 min of both control and LBPP periods. LBPP caused a decrease in leg fluid volume and an increase in neck circumference that did not differ between men and women. However, compared with the control period, LBPP induced a much greater increase in Pcrit in men than in women (7.2+/-1.8 compared with 2.0+/-1.5 cm H2O, P=0.035). We conclude that rostral fluid displacement by LBPP increases UA collapsibility more in healthy, non-obese men than in women. This may be one mechanism contributing to the higher prevalence of OSA in men than in women.
