A qualitative analysis of an online teaching intervention to encourage favorable attitudes toward influenza vaccine among community college students.

Objective: To promote influenza vaccine acceptance among community college students during the Fall 2020 semester to reduce the incidence of a "twin-demic" occurring of influenza and COVID-19. Participants: A convenience sample of 185 students enrolled in an entry level health course. Methods: Non-experimental cross-sectional design that used a self-paced, online teaching intervention. Qualitative data in the form of online discussion board posts were collected and analyzed assessing attitudes, normative references, and knowledge. Results: High rates of favorable attitudes toward influenza vaccine, evidence of subjective normative references toward science-based information, and an increase in participant knowledge. Conclusions: An online teaching intervention can be effective in changing attitudes, referencing subjective norms related to scientific information, and increasing knowledge.

What do we know about patients' perspectives and expectations relating to palliative and end-of-life care in advanced liver disease? A systematic review of qualitative literature using ENTREQ guidelines.

BACKGROUND: Liver disease, a major cause of death worldwide, affects younger people compared with other major causes of death. Palliative and end-of-life care for these patients are often overlooked. Guidelines are emerging on what good end-of-life care in liver disease should look like, but there is a dearth of research into patients' perspectives even though they are most affected by these guidelines. AIM: To explore current knowledge and understanding of patients' lived experiences, perspectives and expectations in relation to palliative and end-of-life care in advanced liver disease. DESIGN: Systematic review with thematic synthesis complying to the enhancing transparency in reporting the synthesis of qualitative research (ENTREQ) statement. SETTING AND PARTICIPANTS: Database searches (Ovid Medline, 1946-2021 and Web of Science, 1970-2021) to identify qualitative studies exploring patients' perspectives of palliative and end-of-life care in advanced liver disease. FINDINGS: Only eight articles met all criteria. Themes demonstrated repeated hospital admissions towards the end of life, lack of coordinated care in community and barriers in discussion about palliative care in end-stage liver disease due to lack of confidence among professionals and a negative view about palliative care among patients and carers. Emotional, financial and disability-related needs of patients and their carers are often neglected. CONCLUSION: There is a dearth of studies exploring patients' perspectives about care in advanced liver disease relating to palliative and end-of-life care. Lack of coordinated community support and honest conversations around palliative care leads to reduced quality of life. More primary research from diverse population is needed to improve palliative care and end-of-life care in end-stage liver disease.

Non-malarial febrile illness: a systematic review of published aetiological studies and case reports from Southern Asia and South-eastern Asia, 1980-2015.

BACKGROUND: In the absence of definitive diagnosis, healthcare providers are likely to prescribe empirical antibacterials to those who test negative for malaria. This problem is of critical importance in Southern Asia (SA) and South-eastern Asia (SEA) where high levels of antimicrobial consumption and high prevalence of antimicrobial resistance have been reported. To improve management and guide further diagnostic test development, better understanding is needed of the true causative agents of fever and their geographical variability. METHODS: We conducted a systematic review of published literature (1980-2015) to characterise the spectrum of pathogens causing non-malarial febrile illness in SA and SEA. We searched six databases in English and French languages: MEDLINE, EMBASE, Global Health (CABI) database, WHO Global Health Library, PASCAL, and Bulletin de la Société Française de Parasitologie (BDSP). Selection criteria included reporting on an infection or infections with a confirmed diagnosis, defined as pathogens detected in or cultured from samples from normally sterile sites, or serological evidence of current or past infection. RESULTS: A total of 29,558 records from 19 countries in SA and SEA were screened, of which 2410 (8.1%) met the selection criteria. Bacterial aetiologies were reported in 1235 (51.2%) articles, viral in 846 (35.1%), parasitic in 132 (5.5%), and fungal in 54 (2.2%), and 143 (6.0%) articles reported more than one pathogen group. In descending order of frequency, Salmonella Typhi, Escherichia coli, Staphylococcus aureus, Klebsiella pneumoniae, and coagulase negative Staphylococcus were the commonly reported bacteria, while dengue virus, chikungunya virus, Japanese encephalitis virus, hepatitis B virus, and hepatitis C virus were common viral pathogens reported. Reports of rarely reported or emerging pathogens included a case report of Borrelia burgdorferi (Lyme disease) in India in 2010 and reports of Nipah virus in Singapore and India. CONCLUSIONS: This review summarises the reported non-malaria pathogens that may cause febrile illness in SA and SEA. The findings emphasise the need of standardising the reporting of aetiological studies to develop effective, evidence-based fever management and improved surveillance. Research and development of diagnostic tools would benefit from up-to-date epidemiological reporting of the regional diversities of non-malaria fever aetiologies.

Non-malarial febrile illness: a systematic review of published aetiological studies and case reports from Africa, 1980-2015.

BACKGROUND: The availability of reliable point-of-care tests for malaria has heralded a paradigm shift in the management of febrile illnesses away from presumptive antimalarial therapy. In the absence of a definitive diagnosis, health care providers are more likely to prescribe empirical antimicrobials to those who test negative for malaria. To improve management and guide further test development, better understanding is needed of the true causative agents and their geographic variability. METHODS: A systematic review of published literature was undertaken to characterise the spectrum of pathogens causing non-malaria febrile illness in Africa (1980-2015). Literature searches were conducted in English and French languages in six databases: MEDLINE, EMBASE, Global Health (CABI), WHO Global Health Library, PASCAL, and Bulletin de la Société Française de Parasitologie (BDSP). Selection criteria included reporting on an infection or infections with a confirmed diagnosis, defined as pathogens detected in or cultured from samples from normally sterile sites, or serological evidence of current or past infection. A number of published articles (rather than incidence or prevalence) reporting a given pathogen were presented. RESULTS: A total of 16,523 records from 48 African countries were screened, of which 1065 (6.4%) met selection criteria. Bacterial infections were reported in 564 (53.0%) records, viral infections in 374 (35.1%), parasitic infections in 47 (4.4%), fungal infections in nine (0.8%), and 71 (6.7%) publications reported more than one pathogen group. Age range of the study population was not specified in 233 (21.9%) publications. Staphylococcus aureus (18.2%), non-typhoidal Salmonella (17.3%), and Escherichia coli (15.4%) were the commonly reported bacterial infections whereas Rift Valley fever virus (7.4%), yellow fever virus (7.0%), and Ebola virus (6.7%) were the most commonly reported viral infections. Dengue virus infection, previously not thought to be widespread in Africa, was reported in 54 (5.1%) of articles. CONCLUSIONS: This review summarises the published reports of non-malaria pathogens that may cause febrile illness in Africa. As the threat of antimicrobial resistance looms, knowledge of the distribution of infectious agents causing fever should facilitate priority setting in the development of new diagnostic tools and improved antimicrobial stewardship.

Randomized, Blinded, Dose-Ranging Trial of an Ebola Virus Glycoprotein Nanoparticle Vaccine With Matrix-M Adjuvant in Healthy Adults.

BACKGROUND: Ebola virus (EBOV) epidemics pose a major public health risk. There currently is no licensed human vaccine against EBOV. The safety and immunogenicity of a recombinant EBOV glycoprotein (GP) nanoparticle vaccine formulated with or without Matrix-M adjuvant were evaluated to support vaccine development. METHODS: A phase 1, placebo-controlled, dose-escalation trial was conducted in 230 healthy adults to evaluate 4 EBOV GP antigen doses as single- or 2-dose regimens with or without adjuvant. Safety and immunogenicity were assessed through 1-year postdosing. RESULTS: All EBOV GP vaccine formulations were well tolerated. Receipt of 2 doses of EBOV GP with adjuvant showed a rapid increase in anti-EBOV GP immunoglobulin G titers with peak titers observed on Day 35 representing 498- to 754-fold increases from baseline; no evidence of an antigen dose response was observed. Serum EBOV-neutralizing and binding antibodies using wild-type Zaire EBOV (ZEBOV) or pseudovirion assays were 3- to 9-fold higher among recipients of 2-dose EBOV GP with adjuvant, compared with placebo on Day 35, which persisted through 1 year. CONCLUSIONS: Ebola virus GP vaccine with Matrix-M adjuvant is well tolerated and elicits a robust and persistent immune response. These data suggest that further development of this candidate vaccine for prevention of EBOV disease is warranted.

Scrub typhus ecology: a systematic review of Orientia in vectors and hosts.

Scrub typhus, caused by Orientia tsutsugamushi, is an important and neglected vector-borne zoonotic disease with an expanding known distribution. The ecology of the disease is complex and poorly understood, impairing discussion of public health interventions. To highlight what we know and the themes of our ignorance, we conducted a systematic review of all studies investigating the pathogen in vectors and non-human hosts. A total of 276 articles in 7 languages were included, with 793 study sites across 30 countries. There was no time restriction for article inclusion, with the oldest published in 1924. Seventy-six potential vector species and 234 vertebrate host species were tested, accounting for over one million trombiculid mites ('chiggers') and 83,000 vertebrates. The proportion of O. tsutsugamushi positivity was recorded for different categories of laboratory test and host species. Vector and host collection sites were geocoded and mapped. Ecological data associated with these sites were summarised. A further 145 articles encompassing general themes of scrub typhus ecology were reviewed. These topics range from the life-cycle to transmission, habitats, seasonality and human risks. Important gaps in our understanding are highlighted together with possible tools to begin to unravel these. Many of the data reported are highly variable and inconsistent and minimum data reporting standards are proposed. With more recent reports of human Orientia sp. infection in the Middle East and South America and enormous advances in research technology over recent decades, this comprehensive review provides a detailed summary of work investigating this pathogen in vectors and non-human hosts and updates current understanding of the complex ecology of scrub typhus. A better understanding of scrub typhus ecology has important relevance to ongoing research into improving diagnostics, developing vaccines and identifying useful public health interventions to reduce the burden of the disease.

An online mapping database of molecular markers of drug resistance in Plasmodium falciparum: the ACT Partner Drug Molecular Surveyor.

BACKGROUND: Prior to this project, only a handful of online visualizations existed for exploring the published literature on molecular markers of antimalarial drug resistance, and none specifically for the markers associated with Plasmodium falciparum resistance to the partner drugs in artemisinin-based combination therapy (ACT). Molecular information is collected in studies with different designs, using a variety of molecular methodologies and data analysis strategies, making it difficult to compare across studies. The purpose of this project was to develop a free online tool, which visualizes the widely published data on molecular markers of antimalarial drug resistance, starting with the two genes pfcrt and pfmdr-1, associated with resistance to the three most common partner drugs; amodiaquine, lumefantrine and mefloquine. METHODS: A literature review was conducted, and a standardized method was used to extract data from publications, and critical decisions on visualization were made. A global geospatial database was developed of specific pfmdr1 and pfcrt single nucleotide polymorphisms and pfmdr1 copy number variation. An informatics framework was developed that allowed flexibility in development of the tool over time and efficient adaptation to different source data. RESULTS: The database discussed in this paper has pfmdr1 and pfcrt marker prevalence information, from 579 geographic sites in 76 different countries, including results from over 86,000 samples from 456 articles published January 2001-May 2017. The ACT Partner Drugs Molecular Surveyor was launched by the WorldWide Antimalarial Resistance Network (WWARN) in March 2015 and it has attracted over 3000 unique visitors since then. Presented here is a demonstration of how the Surveyor database can be explored to monitor local, temporal changes in the prevalence of molecular markers. Here publications up to May 2017 were included, however the online ACT partner drug Molecular Surveyor is continuously updated with new data and relevant markers. CONCLUSIONS: The WWARN ACT Partner Drugs Molecular Surveyor summarizes data on resistance markers in the pfmdr1 and pfcrt genes. The database is fully accessible, providing users with a rich resource to explore and analyze, and thus utilize a centralized, standardized database for different purposes. This open-source software framework can be adapted to other data, as demonstrated by the subsequent launch of the Artemisinin Molecular Surveyor and the Vivax Surveyor.

An inventory of supranational antimicrobial resistance surveillance networks involving low- and middle-income countries since 2000.

Low- and middle-income countries (LMICs) shoulder the bulk of the global burden of infectious diseases and drug resistance. We searched for supranational networks performing antimicrobial resistance (AMR) surveillance in LMICs and assessed their organization, methodology, impacts and challenges. Since 2000, 72 supranational networks for AMR surveillance in bacteria, fungi, HIV, TB and malaria have been created that have involved LMICs, of which 34 are ongoing. The median (range) duration of the networks was 6 years (1-70) and the number of LMICs included was 8 (1-67). Networks were categorized as WHO/governmental (n = 26), academic (n = 24) or pharma initiated (n = 22). Funding sources varied, with 30 networks receiving public or WHO funding, 25 corporate, 13 trust or foundation, and 4 funded from more than one source. The leading global programmes for drug resistance surveillance in TB, malaria and HIV gather data in LMICs through periodic active surveillance efforts or combined active and passive approaches. The biggest challenges faced by these networks has been achieving high coverage across LMICs and complying with the recommended frequency of reporting. Obtaining high quality, representative surveillance data in LMICs is challenging. Antibiotic resistance surveillance requires a level of laboratory infrastructure and training that is not widely available in LMICs. The nascent Global Antimicrobial Resistance Surveillance System (GLASS) aims to build up passive surveillance in all member states. Past experience suggests complementary active approaches may be needed in many LMICs if representative, clinically relevant, meaningful data are to be obtained. Maintaining an up-to-date registry of networks would promote a more coordinated approach to surveillance.

Caribbean (English-Speaking) Women in the United States: Cooking for Diabetes Prevention and Management.

This study surveyed 152 Caribbean-American women about their acculturation levels; their health behaviors; and their perceptions about a website portal for diabetes prevention and management. Participants followed a study link to documents created via SurveyMonkey. The study link included seven edited videos each fewer than 2 min; the videos included ingredients; preparation/cooking instructions; and plating tips for modifying traditional Caribbean meals for diabetes management and prevention. Overall engagement in six healthy living behaviors was moderate Mean = 2.07; Minimum = 1 (Never); Maximum = 3.0 (Always). Self-efficacy for cooking 'healthy' before exploring the website was a mean 3.52 between 40 and 60% confident (SD = 1.509) versus the after Mean of 4.59 closest to 80% confident (SD = 1.154); t = - 10.353, df = 147 (P < 0.001). The results suggest the website did serve as a brief intervention for increasing self-efficacy in cooking meals more consistent with diabetes prevention and management.

Patient and Physician Factors Associated with Undisclosed Prostate Cancer Screening in a Sample of Predominantly Immigrant Black Men.

Medical guidelines do not recommend prostate cancer screening, particularly without informed and shared decision making. This study investigates undisclosed opportunistic screening using prostate specific antigen (PSA) testing in black immigrant and African American men. Participants (N = 142) were insured urban men, 45- to 70-years old. Patients' reports of testing were compared with medical claims to assess undisclosed PSA testing. Most (94.4 %) men preferred to share in screening decisions, but few (46.5 %) were aware PSA testing was performed. Four factors predicted being unaware of testing: low formal education, low knowledge about prostate cancer, no intention to screen, and no physician recommendation (all p's < .05). Undisclosed PSA testing was common. Both patient and provider factors increased risk of being uninformed about prostate cancer screening. Interventions combining patient education and physician engagement in shared decision making may better align practice with current prostate cancer screening guidelines.

Don't go with the 'FLO' - a student mobile texting service to enhance nursing student retention.

BACKGROUND: The review undertaken revealed that there is an abundance of literature concerning retention and the high levels of attrition among undergraduate students and of relevance here, nurse education. The study undertaken evaluated the use of mobile phone automated texts designed to provide information, support and reassurance to help alleviate the stress and anxieties that some undergraduate nursing students experience during the early phase of their studies and which can lead to some students leaving their programme. OBJECTIVE: The objective of the study was to evaluate how use of automated mobile phone texts, using a system known as FLO, could usefully supplement pastoral support, as an intervention to reduce attrition among undergraduate nursing students. DESIGN: A qualitative and quantitative evaluation was conducted using an open-ended questionnaire designed specifically for the study. PARTICIPANTS: The sample were two cohorts of undergraduate first year student nurses (n=178). Of these 123 (69%) signed up to FLO and 77 (63%) completed the evaluation form. METHODS: The evaluation form that was administered in a classroom situation one week after use of FLO had ceased. Data were analysed through use of a descriptive statistics and thematic analysis approaches. RESULTS: A range of key themes emerged from the analysis including that text messages were helpful and supportive, increased a sense of belonging to the University and encouraged retention. There were some unresolved issues concerning the costs incurred by participants when sending reply text messages. CONCLUSIONS: It is concluded that FLO or use of similar mobile phone protocols can be a useful addition to approaches to improve undergraduate nursing student retention rates.

The impact of greyscale inversion for nodule detection in an anthropomorphic chest phantom: a free-response observer study.

OBJECTIVE:: The aim of this work was to assess the impact of greyscale inversion on nodule detection on posteroanterior chest X-ray images. Previous work has attempted this, with no consensus opinion formed. We assessed the value of "fast-flicking" between standard and inverted display modes for nodule detection. METHODS:: Six consultant radiologists (with 5-32 years' reporting experience) completed an observer task under the free-response paradigm. An anthropomorphic chest phantom was loaded with 50 different configurations of simulated nodules (1-4 nodules per case) measuring 5, 8, 10 and 12 mm in spherical diameter; each configuration represented a single case. In addition, 25 cases contained no nodules. Images were displayed in three modes: (i) standard, (ii) inverted and (iii) fast-flicking between standard and inverted display modes. Each observer completed the study in a different order of display (i, ii, iii) using a calibrated 5-megapixel monitor. Nodules were localized with mouse clicks and ratings assigned using a 1-10 discrete slider-bar confidence scale. Rjafroc (Pittsburgh, PA) was used for data analysis; differences in nodule detection performance were considered significant at 0.05. RESULTS:: The observer-averaged weighted jackknife alternative free-response receiver-operating characteristic figures of merit were 0.715 (standard), 0.684 (inverted) and 0.717 (fast-flicking). Random-reader fixed-case analysis revealed no statistically significant difference between any treatment pair [F(2,8) = 1.22; p = 0.345]. CONCLUSION:: No statistically significant difference in nodule detection was found for the three display conditions. ADVANCES IN KNOWLEDGE:: We have investigated the impact of fast-flicking between standard and inverted display modes for the detection of nodules. We found no benefit.

A qualitative study of parents' experiences using family support services: applying the concept of surface and depth.

United Kingdom policy and practice endorses family support for child well-being. Achieving such support requires multi-agency approaches that consider all aspects of parents' and children's lives and which offer practical, social and emotional help. The potential for services to make a positive impact on parents and their families will depend in part on the level and nature of engagement. In this paper, a case is made for the application of the two-part surface and depth concept for understanding how practitioners engage with families and how they might improve the chances of supporting sustainable differences for parents and families. To illustrate, qualitative data from a review of family centre support provided by a north of England local authority are presented. The review was commissioned to explore why families often need to re-engage with intensive support services. Data were drawn from interviews with parents (n = 18, recruited following a survey of all those registered with the service during April-May 2009) and discussions with family centre support workers (n = 4), and following thematic analysis, three dominant themes emerged--resources available, staff approach and real life--which were appraised in the light of the surface and depth concept. Much of the work with parents effectively dealt with pressing needs. This felt gratifying for both parent and worker and supported immediate service engagement. However, each noted that the more complex issues in parents' lives went unchallenged and thus the sustainability of progress in terms of parenting practice was questionable. A strengths focused approach by staff that understood needs in the context of parents' real-life circumstances was important to parent engagement. Thus, longer term benefits from family support require practitioners to work with parents to problem solve immediate issues while also digging deeper to acknowledge and seek to resolve the more complex challenges parents face in their real lives.

Should preparation for elite sporting participation be included in the rehabilitation process of war-injured veterans?

BACKGROUND: Participation in sport and exercise training, while aiding in the reintegration and confidence building of wounded service personnel, also has potential to prepare them for elite sport competition. It is this encouragement of the war injured to use sport and recreational physical activity as a means of rehabilitation back into civilian life, which has become the worldwide phenomenon of Paralympic sport. OBJECTIVES: This paper evaluates existing research relating to the incidence of types of war injuries and the use of sport within the rehabilitation process. STUDY DESIGN: Literature review. METHODS: Initial searches were conducted in the electronic databases EBSCOHost, ScienceDirect and Pubmed using the keywords 'veterans' and 'sport' or 'physical activity'. These searches were then supplemented by tracking all key references from the appropriate articles identified. A narrative literature review methodology was employed. RESULTS: Although it is clear from the reported literature that further development of available rehabilitation services is necessary to provide the required level of care for the types of mental and physical injuries and the concept of 'therapeutic recreation' is becoming popular, there is still a need for the development of specific protocols to identify individuals who can participate and excel in a specific sport at an elite level. CONCLUSIONS: Drawing on the US military experience it can be argued that sport in the UK and other parts of the world should be more widely recognized as a component of rehabilitation. This is not just for the role that sport can play as a tool for rehabilitation but also for the intrinsic and extrinsic benefits that participation in elite sport can offer.

Informed decision making about prostate cancer testing in predominantly immigrant black men: a randomized controlled trial.

BACKGROUND: Decision support interventions have been developed to help men clarify their values and make informed decisions about prostate cancer testing, but they seldom target high-risk black and immigrant men. PURPOSE: This study evaluated the efficacy of a decision support intervention focused on prostate cancer testing in a sample of predominantly immigrant black men. METHODS: Black men (N = 490) were randomized to tailored telephone education about prostate cancer testing or a control condition. RESULTS: Post-intervention, the intervention group had significantly greater knowledge, lower decision conflict, and greater likelihood of talking with their physician about prostate cancer testing than the control group. There were no significant intervention effects on prostate specific antigen testing, congruence between testing intention and behavior, or anxiety. CONCLUSIONS: A tailored telephone decision support intervention can promote informed decision making about prostate cancer testing in black and predominantly immigrant men without increasing testing or anxiety.
