Guidance on Mitigating the Risk of Transmitting Respiratory Infections During Nebulization by the COPD Foundation Nebulizer Consortium.

BACKGROUND: Nebulizers are used commonly for inhaled drug delivery. Because they deliver medication through aerosol generation, clarification is needed on what constitutes safe aerosol delivery in infectious respiratory disease settings. The COVID-19 pandemic highlighted the importance of understanding the safety and potential risks of aerosol-generating procedures. However, evidence supporting the increased risk of disease transmission with nebulized treatments is inconclusive, and inconsistent guidelines and differing opinions have left uncertainty regarding their use. Many clinicians opt for alternative devices, but this practice could impact outcomes negatively, especially for patients who may not derive full treatment benefit from handheld inhalers. Therefore, it is prudent to develop strategies that can be used during nebulized treatment to minimize the emission of fugitive aerosols, these comprising bioaerosols exhaled by infected individuals and medical aerosols generated by the device that also may be contaminated. This is particularly relevant for patient care in the context of a highly transmissible virus. RESEARCH QUESTION: How can potential risks of infections during nebulization be mitigated? STUDY DESIGN AND METHODS: The COPD Foundation Nebulizer Consortium (CNC) was formed in 2020 to address uncertainties surrounding administration of nebulized medication. The CNC is an international, multidisciplinary collaboration of patient advocates, pulmonary physicians, critical care physicians, respiratory therapists, clinical scientists, and pharmacists from research centers, medical centers, professional societies, industry, and government agencies. The CNC developed this expert guidance to inform the safe use of nebulized therapies for patients and providers and to answer key questions surrounding medication delivery with nebulizers during pandemics or when exposure to common respiratory pathogens is anticipated. RESULTS: CNC members reviewed literature and guidelines regarding nebulization and developed two sets of guidance statements: one for the health care setting and one for the home environment. INTERPRETATION: Future studies need to explore the risk of disease transmission with fugitive aerosols associated with different nebulizer types in real patient care situations and to evaluate the effectiveness of mitigation strategies.

Updated Trends in Inferior Vena Cava Filter Use by Indication in the United States After Food and Drug Administration Safety Warnings: A Decade Analysis From 2010 to 2019.

BACKGROUND: Overall inferior vena cava filter (IVCF) utilization has decreased in the United States since the 2010 US Food and Drug Administration (FDA) safety communication. The FDA renewed this safety warning in 2014 with additional mandates on reporting IVCF-related adverse events. We evaluated the impact of the FDA recommendations on IVCF placements for different indications from 2010 to 2019 and further assessed utilization trends by region and hospital teaching status. METHODS: Inferior vena cava filter placements between 2010 and 2019 were identified in the Nationwide Inpatient Sample database using the associated International Classification of Diseases, Ninth Revision, Clinical Modification, and Tenth Revision codes. Inferior vena cava filter placements were categorized by indication for venous thromboembolism (VTE) "treatment" in patients with VTE diagnosis and contraindication to anticoagulation and "prophylaxis" in patients without VTE. Generalized linear regression was used to analyze utilization trends. RESULTS: A total of 823 717 IVCFs were placed over the study period, of which 644 663 (78.3%) were for VTE treatment and 179 054 (21.7%) were for prophylaxis indications. The median age for both categories of patients was 68 years. The total number of IVCFs placed for all indications decreased from 129 616 in 2010 to 58 465 in 2019, with an aggregate decline rate of -8.4%. The decline rate was higher between 2014 and 2019 than between 2010 and 2014 (-11.6% vs -7.2%). From 2010 to 2019, IVCF placement for VTE treatment and prophylaxis trended downward at rates of -7.9% and -10.2%, respectively. Urban nonteaching hospitals saw the highest decline for both VTE treatment (-17.2%) and prophylactic indications (-18.0%). Hospitals located in the Northeast region had the highest decline rates for VTE treatment (-10.3%) and prophylactic indications (-12.5%). CONCLUSION: The higher decline rate in IVCF placements between 2014 and 2019 compared with 2010 and 2014 suggests an additional impact of the renewed 2014 FDA safety indications on national IVCF utilization. Variations in IVCF use for VTE treatment and prophylactic indications existed across hospital teaching types, locations, and regions. CLINICAL IMPACT: Inferior vena cava filters (IVCF) are associated with medical complications. The 2010 and 2014 FDA safety warnings appeared to have synergistically contributed to a significant decline in IVCF utilization rates from 2010 - 2019 in the US. IVC filter placements in patients without venous thromboembolism (VTE) declined at a higher rate than VTE. However, IVCF utilization varied across hospitals and geographical locations, likely due to the absence of universally accepted clinical guidelines on IVCF indications and use. Harmonization of IVCF placement guidelines is needed to standardize clinical practice, thereby reducing the observed regional and hospital variations and potential IVC filter overutilization.

Adult education and entrepreneurship: getting young adults involved.

This paper reflects on adult education and the fostering of an entrepreneurial mindset. It solicits roles adult education, especially the non-formal education (NFE), could play in fostering entrepreneurial mindset of young adults. It examines short-to-medium, and long-term plans of young adults in nurturing growth and enterprising mindsets through involvement in NFE endeavours. It probes into entrepreneurial opportunities and challenges in the communities that young adults could recognise and create enterprises for themselves. This is a narrative case study which purposively selected, as the unit of analysis, an adult learner who was operating a micro-enterprise and pursuing a degree programme at Accra Learning Centre. An in-depth telephone interview was conducted to garner stories and experiences young adult have had innovating with an entrepreneurial mindset. Thematic, analytical, narrative and interpretivist approaches were adapted in presenting the results. The participant had a good experience in his start up, he learned lessons, and worked hard to grow his micro-enterprises. The savings culture he built allowed him to cope with difficulties posed by Covid-19 pandemic to his micro-enterprises. Governments and stakeholders in entrepreneurship should via policy, advisory and financial support motivate young adults to invest in entrepreneurship and create sustainable jobs for themselves.

Diversities in the place of delivery choice: a study among expectant mothers in Ghana.

BACKGROUND: In this study, the factors that influence the choice of place of delivery among expectant mothers in both rural and urban settings in the northern part of Ghana were identified and compared using the conceptual framework provided by Thaddeus and Maine. METHODS: A mixed-method study was used to examine expectant mothers and their responses related to factors that affect their choice of place of delivery through a concurrent triangulation using health professional interviews and a detailed participant survey. The sample consisted of 552 expectant mothers between the ages of 15 and 49 years. Individual interviews were conducted with 8 health professionals. There was also a focus group discussion with randomly selected pregnant women and lactating mothers. Themes were generated through open coding of the interview data, while multiple regression was performed to identify the factors associated with choice of place of delivery. RESULTS: Major preference (60.1%) was for home delivery among rural dwellers compared to 20.7% for urban participants. Statistically significant variables affecting the choice of place of delivery among study participants were found to be educational background, the experience of previous deliveries, the attitude of hospital staff toward pregnant women during labor, and frequency of accessing antenatal care. CONCLUSION: Majority of rural women prefer home delivery to facility delivery which is the opposite of the trend observed among urban women. The study's implications may lead to positive change where stakeholders develop and implement policies to promote health facility delivery for expectant mothers in Ghana.

Utilization trends and outcomes of catheter-directed thrombolysis for pulmonary embolism in the US by race/ethnicity.

Contemporary data on catheter-directed thrombolysis (CDT) utilization trends and associated hospital outcomes in pulmonary embolism (PE) n the US is limited. Using the nationwide inpatient sample database, we identified patients hospitalized for acute PE treated with CDT from January 1, 2008, to December 31, 2018. Cochrane-Armitage test was used to evaluate the temporal trends in utilization, hospital mortality, and major bleeding rates. Multivariate logistic regression was used to compare differences in the outcomes across race/ethnicity, 4444 patients (unweighted hospitalizations) underwent CDT during the study period. The mean age ± standard deviation of the population was 58 ± 16 years and the majority were males (54%). 3269 (73.6%) patients were non-Hispanic White (NHW), 802 (18.0%) patients were non-Hispanic Black (NHB), and 373 (8.4%) patients were of 'other' races/ethnicities. There was a more than tenfold increase in CDT use in 2018 compared to 2008. The total mortality and bleeding rates were approximately 7 and 10% respectively. Hospital mortality rates trended down across all races/ethnicities during the study period. A similar downward trend in bleeding rates was noted in NHB only (28.6% vs 10.7%, p = 0.04). In-hospital mortality and major bleeding odds were comparable across all races/ethnicities were comparable. NHB patients and other races were more likely to require blood transfusion and incur higher hospitalization costs compared with NHW patients. CDT use increased significantly in the US during the study period with a corresponding downward trend in in-hospital mortality across all races, and bleeding rates in NHB.

Antiretroviral therapy adherence and viral suppression among HIV-infected adolescents and young adults at a tertiary hospital in Ghana.

With the introduction of antiretroviral therapy (ART), many HIV-infected children are growing into adolescence and adulthood. A facility-based cross-sectional study was conducted at the Fevers Unit of one of the teaching hospitals in Ghana. The Morisky Medication Adherence Scale (MMAS-8) and pill count were used to assess adherence, while measured viral load levels of participants were used to assess viral suppression. The rate of viral suppression (<400 copies/ml) was 68.2%. Participants with high MMAS-8 scores were 8.4 times more likely to be virally suppressed compared to those with low MMAS-8 scores (OR = 8.4, p = 0.003, 95% CI: 2.11-33.48). The commonest reason for missing doses of their antiretroviral drugs (ARVs) was forgetfulness. Efforts must be made by all stakeholders involved in HIV care to engage adolescents and young adults living with HIV (AYALHIV) on personal and/or group levels to help identify and improve particular ART adherence issues so as to increase viral suppression rates.

Successful Use of Hyperbaric Oxygen as Adjunctive Therapy for a Nonhealing Venous Ulcer in a Patient with Systemic Sclerosis and Pulmonary Arterial Hypertension: A Case Report and Review of the Literature.

Skin ulcers are a common complication of systemic sclerosis (SSc) that can significantly impact the quality of life. There have been recent reports on the use of hyperbaric oxygen therapy (HBO2T) in the management of nonhealing systemic sclerosis skin ulcers. The effect of HBO2T on pulmonary arterial hypertension (PAH), another common and potentially life-threatening complication of SSc, is unclear with literature on the subject lacking. We present the case of a 65-year-old female with limited SSc complicated by severe PAH and a nonhealing left lower extremity venous ulcer. HBO2T was successfully used as an adjunct in her management resulting in complete resolution of the venous ulcer and improved quality of life without any adverse effects on her pulmonary arterial hypertension.

Chylothorax and Chylopericardium: A Complication of Long-Term Central Venous Catheter Use.

The development of chylothorax and chylopericardium is an uncommon complication of the long-term use of central venous catheters. We describe a unique case of an end stage renal disease patient on hemodialysis with a left jugular tunneled catheter who developed superior vena cava syndrome. Our patient presented with both a large pleural and pericardial effusion that despite drainage continued to reaccumulate. Further imaging with CT scan of the thorax revealed stenosis of the superior vena cava leading to recurrent chylothorax and chylopericardium.

High rates of cerebral toxoplasmosis in HIV patients presenting with meningitis in Accra, Ghana.

Background: Data on adult meningitis among patients infected with the human immunodeficiency virus (HIV) is scarce in western sub-Saharan Africa, including Ghana. Methods: HIV-infected adults with a provisional diagnosis of meningitis were consecutively enrolled, between August 2014 and January 2016. After patient data collection, cerebrospinal fluid (CSF) was obtained and evaluated for microbiological aetiologies, cell counts and biochemistry. Caregiver clinicians provided limited data for inpatients at the end-point of discharge or death. Results: Complete data sets from 84 patients were analysed (inpatients=63, outpatients=21). Median age was 40 years with 56% (47/84) being females. Only 30% (25/84) of the patients were on antiretroviral therapy (ART). CD4+ T-cell count was available for 81% (68/84) of patients and 61.9% (52/84) had counts below 150 cells/µL [median and interquartile range=56 (13.8-136)]. Microbiological aetiologies were detected in 60.7% (51/84) patients with the following distribution-Toxoplasmosis (25%), Epstein-Barr virus (28.6%), Cytomegalovirus and Cryptococcus (2.4%) each. Co-infection was identified in 20.7% (17/84) of the patients. Conclusion: Patients presenting with symptoms of meningitis had advanced HIV/AIDS, a quarter of whom had cerebral toxoplasmosis or infection with EBV. A high index of suspicion, laboratory exclusion of cryptococcal meningitis and prompt patient management with anti-toxoplasmosis empiric therapy may thus be required for optimal treatment.
