Respiratory Protection: Lessons Learned from a Global Pandemic.

The COVID-19 pandemic exposed the limitations of global health systems' abilities to manage the rapid spread of a novel infectious disease, which was exacerbated by shortages of respiratory protective devices and other critical personal protective equipment (PPE). An advisory panel of experienced health-care professionals with backgrounds in Occupational and Environmental Health and Safety (OEHS), Infection Prevention, Nursing, and Clinical Application Specialists convened to discuss challenges and strategies associated with the selection and use of respiratory protective devices as experienced during the first year of the COVID-19 pandemic. This discussion led to the following recommendations: 1) the need for clear communication of alternative respiratory protection selection and use recommendations in accordance with US regulatory and agency guidance; 2) the need for collaboration between Infection Prevention, OEHS, clinical staff, supply chain/materials management, emergency preparedness, executive leadership, and finance; 3) the need for adequate stockpiling, inventory rotation, and diverse respiratory protection options to accommodate the majority of health-care workers; 4) the need for efficient and innovative strategies to communicate evolving regulatory, agency, and facility recommendations and to deliver appropriate training on respiratory protection; and 5) the need for additional research on respiratory protection use - involving filtering facepiece respirators (FFRs) as well as other respirator types designed to be reused - to balance infection prevention best practices with a sustainable process. In conclusion, these considerations may offer guidance and identify areas for research on preparedness, communication, education, and training to enhance the preparation of health-care facilities including community-based health-care organizations for unexpected public health events.

A systematic review on the role of trust in the water governance literature.

Trust is generally considered to play a key enabling role in water governance. Despite this notion, there have been no systematic assessments examining the way in which the literature on water governance engages with 'trust'. Our article fills this gap by providing an overview of the way in which this literature has engaged with trust as a conceptual lens, analytical device and empirical phenomenon. Through an explorative systematic literature review of N = 200, mainly peer-reviewed journal articles, our findings reveal that the knowledge base on the role of trust in water governance is fragmented, poorly conceptualized, and contextually dispersed. We also observe that the role of trust is often understudied, especially in the context of the global south and with regard to ethnic minorities and indigenous people as the subjects of trust. We recommend that future research should build on solid empirical evidence, diversify its foci, go beyond an instrumental approach to trust and rely on clear and transparent conceptualizations that acknowledge the context-specific and dynamic nature of trust relationships. The results of this review should serve to better systemize future research and to further the understanding on the role(s) of trust in varying contexts and related to different water governance issues.

Dysphagia treatment post stroke: a systematic review of randomised controlled trials.

BACKGROUND: dysphagia is common following stroke and is associated with the development of pneumonia. Many dysphagia treatment options are available, some still experimental and others already rooted in common practice. Previous reviews of these treatments were limited due to a dearth of available studies. Recently, more trials have been published warranting a re-examination of the evidence. OBJECTIVE: a systematic review of all randomised controlled trials (RCTs), updating previous work and evaluating a broader range of therapeutic interventions intended for use in adults recovering from stroke and dysphagia. METHODS: using multiple databases, we identified RCTs published between the years 1966 and August 2007 examining the efficacy of dysphagia therapies following stroke. Across studies, results of similar treatments and outcomes were compared and evaluated. RESULTS: fifteen articles were retrieved assessing a broad range of treatments that included texture-modified diets, general dysphagia therapy programmes, non-oral (enteral) feeding, medications, and physical and olfactory stimulation. Across the studies there was heterogeneity of the treatments evaluated and the outcomes assessed that precluded the use of pooled analyses. Descriptively these findings present emerging evidence that nasogastric tube feeding is not associated with a higher risk of death compared to percutaneous feeding tubes; and general dysphagia therapy programmes are associated with a reduced risk of pneumonia in the acute stage of stroke. CONCLUSIONS: dysphagia is known to be a common and potentially serious complication of stroke. Despite the recent newly published RCTs, few utilise the same treatment and outcomes thereby limiting the evidence to support the medical effectiveness of common dysphagia treatments used for patients recovering from stroke.

The rehabilitation of patients recovering from brainstem strokes: case studies and clinical considerations.

An estimated 15% of all patients admitted to stroke rehabilitation units experience a brainstem stroke. Two case studies are presented to illustrate some of the difficulties encountered in the rehabilitation of these individuals. Unlike hemispheric stroke, the characteristic consequences of brainstem stroke include ataxia, dysarthria, and diplopia. Additionally, individuals with brainstem stroke may suffer from severe dysphagia and may require enteral feedings. Unlike the rehabilitation of patients with hemispheric stroke, where there is an impressive and relatively comprehensive research literature, there has been surprisingly little research published on the rehabilitation of patients with brainstem stroke despite the fact they represent a significant number of patients admitted to stroke rehabilitation units.

Epidemiology of homicide-suicide events: Oklahoma, 1994-2001.

In Oklahoma, all nonnatural deaths must be reported to the Office of the Chief Medical Examiner (ME), whose trained investigators report cause of death using a centralized, statewide, standardized reporting system. The purpose of this study was to determine temporal trends of Oklahoma homicide-suicide events and characterize the epidemiology of these events. By reviewing all ME reports of homicides and suicides from 1994 through 2001, we identified 73 homicide-suicide events resulting in 73 suicides and 89 homicides. Suicidal perpetrators of homicide-suicide events were most often white men aged >or=30 years who killed a current or ex-spouse or intimate partner. Homicide victims tended to be younger women the same race as their killer. Firearms were the predominant method of death in both homicides and suicides, with handguns used most frequently. Divorce/estrangement was the main contributing factor to these events, and the most common relationship type was possessive. The existence of a statewide, centralized, and computerized ME system and the ability to access the detailed information in the ME narratives were critical to identifying homicide-suicide events and obtaining the type of detailed information necessary to fully investigate these events.

Risk of tornado-related death and injury in Oklahoma, May 3, 1999.

On May 3, 1999, powerful tornadoes, including a category F5 tornado, swept through Oklahoma. The authors examined all tornado-related deaths, hospital admissions, and emergency department visits to identify important risk factors. Data on deaths and injuries directly related to the tornadoes and information obtained from a survey of residents in the damage path of the F5 tornado were used in a case-control analysis. The direct force of the tornadoes caused 40 deaths, 133 hospital admissions, and 265 emergency department outpatient visits. The risk of death from the F5 tornado was greater for persons who were in mobile homes (odds ratio (OR) = 35.3, 95% confidence interval (CI): 7.8, 175.6) or outdoors (OR = 141.2, 95% CI: 15.9, 6,379.8) when the tornado struck than for those in permanently anchored houses. Risk of severe injury was also greater for persons in mobile homes (OR = 11.8, 95% CI: 3.4, 51.7) or outdoors (OR = 34.3, 95% CI: 4.4, 1,526.2). However, the risk of death (OR = 0.0, 95% CI: 0.0, 9.9), severe injury (OR = 0.0, 95% CI: 0.0, 2.0), or minor injury (OR = 0.8, 95% CI: 0.1, 3.1) was not greater among persons in motor vehicles than among those in houses. The risk of death (OR = 0.6, 95% CI: 0.1, 1.7), severe injury (OR = 0.2, 95% CI: 0.1, 0.6), or minor injury (OR = 0.3, 95% CI: 0.2, 0.7) was lower among those fleeing their homes in motor vehicles than among those remaining. Recommendations involving the relative safety of motor vehicles during a tornado should be evaluated using experience from recent tornado events.
