Licensing Requirements for Poultry Veterinary Biologics in the United States

The use of veterinary biologicals is an integral component of poultry health programs. All veterinary biologicals are licensed and sold by manufacturing firms under strict regulation by the U.S. Department of Agriculture to ensure purity, potency, efficacy, and safety of the product. The licensing process for a new vaccine is a complex process involving a defined set of studies for each type of vaccine that are performed by the biologics firm, according to approved protocols, with results submitted to the Center for Veterinary Biologics for review. There are 10 classifications of veterinary biologicals and four types of licenses. Manufacturing and testing procedures are also defined within the licensing process. Licensing requirements were initially codified into law. In addition, guidance documents in the form of memoranda and notices have been published to address licensing for additional classes of vaccines and disease agents. This overview of vaccine licensure in the United States is offered to provide a better understanding of the process, the participants, and the factors that influence the time required to produce a commercial product.

General practitioners' perceptions of the roles of community pharmacists and their willingness to collaborate with pharmacists in primary care

BACKGROUND

Community pharmacists (CPs) have the capacity to contribute to patient care given their expertise in medication and accessibility to residents in the community. However, multidisciplinary patient care programmes where CPs collaborate with general practitioners (GPs) in patient care is rare in Singapore despite increasing healthcare demand.

OBJECTIVES

This study explores GPs' perceptions of CPs' current roles and GPs' ideas for and attitudes towards interprofessional collaboration.

METHODS

Semi-structured qualitative interviews were conducted with 20 private GPs from August to December 2020 via an online video-chat platform. GPs were recruited from the Primacy Care Research Network (pcRn), primary care networks, and using snowballing strategies. All interviews were recorded, transcribed and coded thematically.

RESULTS

Current working relationships between GPs and CPs appeared amicable but limited. GPs appreciate the existing roles of CPs: dispensing drugs not stocked in their practices and clarifying prescription details. Still, GPs appeared to rarely consider collaborative working. GPs acknowledged that CPs could enhance patient care with initiatives including medication reconciliation and advising on using medical devices. It was suggested that CPs could coordinate the purchase of drugs for primary care networks to improve GPs' inventory management, but less enthusiasm was expressed for clinical collaborations with CPs. Major concerns about GP-CP clinical collaborations included direct competition with GPs' own business interests, perceived low acceptability of pharmacy-led services by patients (citing extra time and cost), threat to continuity of care and the absence of a shared patient electronic health record system. Current funding mechanisms do not enable reimbursement of clinical services provided by CPs. Adoption of telemedicine technologies and governmental financial support were identified as possible enablers of GP-CP collaboration.

CONCLUSIONS

GPs saw potential in CPs' increased involvement in patient care, but perceived multiple barriers. Strategies focusing on overcoming these barriers could enable GP-CP collaboration to enhance patient care.

General practitioners’ views on retaining Singapore’s primary care doctors: a cross-sectional survey and qualitative analysis

Background

To support its ageing population and the increasing need for chronic care in the community, Singapore needs to boost the number of doctors in its primary care workforce. To better understand how to improve doctor retention and build a more robust primary care system, we conducted a cross-sectional survey with doctors in general practice and family medicine to explore their career satisfaction, their career plans, factors related to their plans to leave, and their view on retaining GPs in primary care.

Methods

An anonymous online survey was distributed to general practitioners working in the public and private sectors. The survey contained questions on career satisfaction, career plans in the next 5 years, and factors important for retaining doctors in primary care. In addition, there were open-ended questions for respondents to elaborate on retention initiatives and other factors that may improve engagement among primary care doctors. Quantitative data was analyzed with descriptive statistics, principal component analysis, χ2 tests, t-tests, and Pearson’s correlations; qualitative data was analyzed thematically.

Results

The survey was attempted by 355 general practitioners and completed in full by 303. The respondents were most satisfied with rapport with patients and their current professional role; they were least satisfied with the amount of paperwork and the status of general practice in society. In terms of their career plans in the next 5 years, 49/341 (14.4%) of the respondents plan to leave general practice permanently, 43/341 (12.6%) plan to take a career break, and 175/341 (51.3%) plan to reduce their clinical hours. Higher remuneration, recognizing general practice and family medicine as a medical specialty, and reducing the litigious pressures on medical practice were rated as the most important factors for retaining primary care. Free-text responses also revealed a growing dissatisfaction with the Third-Party Administrators that manage insurance arrangements.

Conclusion

While the proportion of doctors who intend to leave is smaller than that reported in overseas studies, our findings highlight an urgent need for targeted interventions to engage and retain primary care doctors. Increasing recognition and support for general practitioners and their professional practice may contribute to strengthening community care for the ageing population.

Recruitment of general practitioners in China: a scoping review of strategies and challenges

Background

China is rapidly expanding its general practitioner (GP) workforce as part of recent healthcare reform, with an extra 400,000 GPs by 2030. This scoping review identifies the published strategies for GP recruitment that are being implemented and the challenges encountered.

Methods

We searched six English and three Chinese databases from 2015 to April 2022, following Arksey and O’Malley’s framework and the PRISMA ScR reporting guidelines.

Results

A total of 40 Chinese-language and 5 English-language records were included. We identified multiple policies, pathways and programmes focused on expanding GP recruitment. Twenty-two evaluations of these initiatives show varying degrees of effectiveness. Selecting general practice as a career is affected by many factors, including individual’s background, remuneration and benefits, career prospects, working environment, self-fulfilment, and current national developments and reorganisations of primary care. The challenge most frequently reported was the adequate provision of qualified GP in rural regions. The targeting of students from rural areas and provision of free education in return for an obligatory six-years’ working in their hometown upon graduation appears to be effective. Extracted records mostly studied views of trainees in a defined locality, and we identified a paucity of studies which explored the perspectives of organisations and institutions, similarly there were areas of China not contributing to the literature and there were no records taking a national perspective.

Conclusions

Long-term monitoring is required to assess policy changes and to systematically evaluate the effectiveness of the interventions nationally. The monitoring of the challenges influencing GP recruitment can be used to inform the design of future initiatives.

Development of a minimum agreed standardised set of outcomes used to measure and report evaluations will help assess the relative contributions and cost effectiveness of different approaches being used to boost GP numbers. We provide suggestions for improving the benefits and rewards for GPs and how to promote recruitment to the more rural or less attractive areas.

Experiences of doctors working in Singapore's public primary healthcare clinics

Despite providing 20 percent of primary healthcare and a larger proportion of care for patients with chronic conditions, little is documented about working in public primary healthcare clinics in Singapore. While previous studies of primary care physicians' occupational stress focused on burnout, this study explores broader personal, professional and organisational factors affecting their experiences. It examines factors influencing doctors working in such clinics to leave or remain in this setting, and the initiatives that would retain and encourage re-entry in the public sector. The study employs a qualitative approach involving semi-structured interviews with 22 doctors conducted between November 2018 and May 2019. These doctors had at least 1 year of experience working in a public primary healthcare clinic. Sixteen of them had left the public sector and six others remaining. Qualitative content analysis was used to interpret the data. The respondents shared three key less favourable themes of working in these clinics; heavy workload and long working hours, short consultation times, and a perceived lack of management's concern about doctors' welfare, and two key valuable experiences of working in this setting; continuity of care and opportunities for academic scholarly activity, including teaching and research. The findings suggest that to retain doctors in these clinics, change is needed at an organisational and structural level. Overall, this study bears important implications for health policy and planning, especially with regard to how the public healthcare system can strike a balance between meeting the demand for high-quality healthcare, and the professional needs of healthcare providers.

Community case managers' challenges collaborating with primary care when managing complex patients in the community: A qualitative study in Singapore

Community case managers (CCMs) play a crucial role in the continuity of care for complex patients in the community. However, they are often considered as non-members of the healthcare team and not actively engaged by the primary care team because of the unique landscape of social services in Singapore. Given that these two distinct professional groups had minimal collaboration previously, integrating CCMs as partners of patient care within the primary care team may pose many challenges. The objective of this qualitative study was to understand the challenges encountered by CCMs when collaborating with primary care services. This exploratory qualitative descriptive study used individual in-depth interviews. CCMs were selected using convenience and snowball sampling. The interviews were semi-structured, guided by a topic guide. Fourteen CCMs were interviewed within a period of 12 weeks (October-December 2018). Thematic analysis was used to analyse the transcripts. Two researchers coded each transcript independently, and a coding framework was agreed upon. Potential themes were then independently developed based on the coding framework. Fourteen individual in-depth interviews were conducted. Six themes emerged from the data, i.e., self-identity, patient factor, inter-professional factor, collaborative culture, confidentiality and organisational structure. Challenges that resonated with previous studies were self-identity, inter-professional factors and confidentiality, whereas other challenges such as patient factors, collaborative culture and organisational structure were unique to Singapore's healthcare landscape. Significant challenges were encountered by CCMs when collaborating with primary care services. Understanding these challenges is key to refining intervention in current models of comprehensive community care between medical and non-medical professionals.

Medical students' attitudes towards and views of general practice careers in Singapore: a cross-sectional survey and qualitative analysis

BACKGROUND

Like many other countries, Singapore needs to support its ageing population by attracting more doctors into general practice (GP) and family medicine (FM). To achieve this requires a better understanding of what attracts or deters medical students. We conducted a cross-sectional survey among medical students in Singapore.

METHODS

An online survey was distributed to students from all three medical schools to understand their likelihood of choosing primary care careers, what they valued in their careers, their attitude towards different aspects of general practice and family medicine relative to other medical fields, and the positive and negative perceptions of primary care held by themselves, their lecturers, and clinical mentors. They were able to elaborate the negativity encountered in the open-ended questions. Quantitative data was analyzed with descriptive statistics, principal component analysis, and linear regression; qualitative data was analyzed thematically.

RESULTS

The survey was completed by 391 students. Slightly over half indicated a likelihood of choosing a career in primary care. For their own careers, the students valued job satisfaction and career development opportunities the most. They perceived careers in primary care as being most likely to offer reasonable hours and close patient relationships, but least likely to offer career advancement potential relative to other medical fields. Their likelihood of choosing primary care careers was significantly predicted by what they value in their own career and their attitudes toward GP/FM relative to other medical fields, but not by the perceptions of GP/FM by others. Free-text responses illustrated how students encounter derogatory comments about GP/FM: the work being "mundane and repetitive", the careers non-competitive, and the doctors poor in clinical competence.

CONCLUSION

While the shortage of primary care doctors is a global issue, our findings highlight the value of situating inquiries in localized contexts. Medical curriculum should emphasize the critical role of primary care in the healthcare system and primary care doctors should be given due recognition to build a strong and motivated primary care workforce to serve the future healthcare needs of the population.

Examining the Trends in Online Health Information-Seeking Behavior About Chronic Obstructive Pulmonary Disease in Singapore: Analysis of Data From Google Trends and the Global Burden of Disease Study

BACKGROUND

Chronic obstructive pulmonary disease (COPD) is the third leading cause of death globally, and timely health care seeking is imperative for its prevention, early detection, and management. While online health information-seeking behavior (OHISB) is increasingly popular due to widespread internet connectivity, little is known about how OHISB for COPD has changed in comparison with the COPD disease burden, particularly at a country-specific level.

OBJECTIVE

This study aimed to examine the trends in OHISB for COPD and how that compared with the estimates of COPD disease burden in Singapore, a highly wired country with a steadily increasing COPD disease burden.

METHODS

To examine the trends in OHISB for COPD, we performed Prais-Winsten regression analyses on monthly search volume data for COPD from January 2004 to June 2020 downloaded from Google Trends. We then conducted cross-correlational analyses to examine the relationship between annualized search volume on COPD topics and estimates of COPD morbidity and mortality reported in the Global Burden of Disease study from 2004 to 2017.

RESULTS

From 2004 to 2020, the trend in COPD search volume was curvilinear (β=1.69, t₁₉₄=6.64, P<.001), with a slope change around the end of 2006. There was a negative linear trend (β=-0.53, t₃₃=-3.57, P=.001) from 2004 to 2006 and a positive linear trend (β=0.51, t₁₅₉=7.43, P<.001) from 2007 to 2020. Cross-correlation analyses revealed positive associations between COPD search volume and COPD disease burden indicators: positive correlations between search volume and prevalence, incidence, years living with disability (YLD) at lag 0, and positive correlations between search volume and prevalence, YLD at lag 1.

CONCLUSIONS

Google search volume on COPD increased from 2007 to 2020; this trend correlated with the upward trajectory of several COPD morbidity estimates, suggesting increasing engagement in OHISB for COPD in Singapore. These findings underscore the importance of making high-quality, web-based information accessible to the public, particularly COPD patients and their carers.

A mobile swabbing booth to address Singapore GPs' concerns about swabber protection: human-centred design during the COVID-19 pandemic

Background

During the COVID-19 pandemic, the Ministry of Health asked Singapore’s private general practitioners (GPs) to perform swab testing in their clinics, but some GPs had concerns about swabber protection. Our aim was to develop a swabbing booth to address these concerns.

Methods

We developed a prototype with potential GP users using a human-centred design approach and piloted it with 10 GP clinics. The pilot was then extended to 170 GP clinics around Singapore. These GPs were then surveyed on user satisfaction.

Results

Ninety-three GPs (54%) responded. The majority (75%) practiced in public residential estates in small practices (mean 1.95 doctors). 86% requested the booth to enhance swabber protection. 74% “would recommend” or “would strongly recommend” the booth to colleagues. 79% continue to use the booth to conduct swab tests. 92% liked that it offered swabber protection. 71% liked that the booth created a separate space for swabbing and 64% liked its ease of disinfection. 47% started swabbing only after receiving the booth and 58% said the booth was “important” or “very important” to their decision to participate in swab testing. However, 34% disliked that it took up too much space and the most frequently critiqued area was the gloves.

Conclusion

The human-centred design approach generated a product that had high user satisfaction, addressed GPs’ concerns of swabber protection and increased GPs’ participation in swab testing. The booth may be useful where GPs are concerned about swabber protection and space is limited.

Teledermatology in Primary Care in Singapore: Experiences of Family Doctors and Specialists

Most teledermatology studies focus on patients’ satisfaction; fewer focus on the experiences of healthcare professionals. This qualitative study explored healthcare professionals’ perceptions of teledermatology used for linking public primary care clinics with the specialist dermatology centre in Singapore. Semistructured in-depth interviews were conducted with 25 family physicians and dermatologists. Six themes were identified: satisfaction with the service; perceived patient benefits; rationale for introducing teledermatology; educational impact; challenges of virtual consultations; and desirable service refinements for the future. Family physicians and dermatologists were positive about the service, but highlighted a need to streamline referral processes and improve the quality of transmitted images. Reduced need for referral to the specialist centre could be achieved by expanding the polyclinic’s pharmacopoeia and treatment modalities. This study highlights the benefits of telemedicine for patient, professionals, and healthcare organizations, and these are reassuring given the widespread and rapid introduction of telemedicine through necessity during the COVID-19 pandemic.

Cytomegalovirus infection is associated with an increase in aortic stiffness in older men which may be mediated in part by CD4 memory T-cells

Human Cytomegalovirus (CMV) infection is associated with atherosclerosis, higher cardiovascular disease (CVD) risk, and an increase in memory T-cells (T_mem). T-cells have also been implicated in CVD, independently of CMV infection. To better understand the CMV-associated CVD risk, we examined the association between CMV (IgG) serostatus and central aortic (carotid-to-femoral) pulse wave velocity (cfPWV), an early, independent predictor of CVD. We also investigated if such an association might be reflected by the distribution of T_mem and/or other T-cell subsets.

Methods: Healthy older volunteers (60-93 years) underwent routine clinical and laboratory evaluation, including assessment of cfPWV in eligible participants. Flow-cytometry was used to assess proportions of memory T-cells, CD28^null T-cells, and CMV-specific T-cells. The following associations were examined; CMV serostatus/cfPWV, CMV serostatus/proportion of T_mem, proportion of T_mem/cfPWV, CD28^null T-cells/cfPWV, and CMV-specific T-cells/cfPWV. Linear regression models were used to adjust for age, sex, socioeconomic status, smoking, waist-to-hip ratio, cholesterol, and blood pressure as required.

Results: Statistically significant positive associations were found (P-values for the fully adjusted models are given); CMV serostatus/cfPWV in men (P ≤ 0.01) but not in women, CMV serostatus/proportions of CD4 T_mem in men (P ≤ 0.05) but not in women; proportions of CD4 T_mem/cfPWV among CMV seropositive (CMV+) people (P ≤ 0.05) but not CMV seronegative (CMV-) people.

Conclusion: CMV infection increases the CVD risk of older men by increasing cfPWV. This may be mediated in part by increased proportions of CD4 T_mem, higher numbers of which are found in CMV+ older people and more so among men than women. Given the high prevalence of CMV worldwide, our findings point to a significant global health issue. Novel strategies to mitigate the increased CVD risk associated with CMV may be required.

Intervertebral disc degeneration and regeneration: a motion segment perspective

Back and neck pain have become primary reasons for disability and healthcare spending globally. While the causes of back pain are multifactorial, intervertebral disc degeneration is frequently cited as a primary source of pain. The annulus fibrosus (AF) and nucleus pulposus (NP) subcomponents of the disc are common targets for regenerative therapeutics. However, disc degeneration is also associated with degenerative changes to adjacent spinal tissues, and successful regenerative therapies will likely need to consider and address the pathology of adjacent spinal structures beyond solely the disc subcomponents. This review summarises the current state of knowledge in the field regarding associations between back pain, disc degeneration, and degeneration of the cartilaginous and bony endplates, the AF-vertebral body interface, the facet joints and spinal muscles, in addition to a discussion of regenerative strategies for treating pain and degeneration from a whole motion segment perspective.

An Overview of Commercially Available Apps in the Initial Months of the COVID-19 Pandemic

Introduction: It has been 4 months since the discovery of COVID-19, and there have been many measures introduced to curb movements of individuals to stem the spread. There has been an increase in the utilization of web-based technologies for counseling, and for supervision and training, and this has been carefully described in China. Several telehealth initiatives have been highlighted for Australian residents. Smartphone applications have previously been shown to be helpful in times of a crisis. Whilst there have been some examples of how web-based technologies have been used to support individuals who are concerned about or living with COVID-19, we know of no studies or review that have specifically looked at how M-Health technologies have been utilized for COVID-19. Objectives: There might be existing commercially available applications on the commercial stores, or in the published literature. There remains a lack of understanding of the resources that are available, the functionality of these applications, and the evidence base of these applications. Given this, the objective of this content analytical review is in identifying the commercial applications that are available currently for COVID-19, and in exploring their functionalities. Methods: A mobile application search application was used. The search terminologies used were "COVID" and "COVID-19." Keyword search was performed based on the titles of the commercial applications. The search through the database was conducted from the 27th March through to the 18th of April 2020 by two independent authors. Results: A total of 103 applications were identified from the Apple iTunes and Google Play store, respectively; 32 were available on both Apple and Google Play stores. The majority appeared on the commercial stores between March and April 2020, more than 2 months after the first discovery of COVID-19. Some of the common functionalities include the provision of news and information, contact tracking, and self-assessment or diagnosis. Conclusions: This is the first review that has characterized the smartphone applications 4 months after the first discovery of COVID-19.

Challenges When Evaluating Cognitive Bias Modification Interventions for Substance Use Disorder

In recent years, advances in experimental psychology have led to a better understanding in automatic, unconscious processes, referred to as attentional and approach biases amongst individuals with substance use disorders. Attentional biases refer to the relatively automatic tendencies for attention to be preferentially allocated towards substance-related cues. Whereas, approach bias refers to the relatively automatic behavioral tendencies of individuals to reach out to substance-related cues in their natural environment. While, several reviews confirm the existence of these biases, and the effectiveness of bias modification, the conduct of cognitive bias modification amongst substance-using individuals is not without its challenges. One of these is that cognitive biases, both attentional and approach biases, are not universally present; and several individual differences factors modulate the magnitude of the biases. Another challenge that investigators faced in their conduct of cognitive bias modification relates to the selection of the appropriate task for bias assessment and modification. Other challenges intrinsic to cognitive bias modification intervention relates to that of participant attrition, much like conventional psychotherapies. Negative findings, of the absence of biases at baseline, or the lack of effectiveness of bias modification have been reported in studies of cognitive bias modification. All these challenges could have an impact on bias assessment and modification. In this perspective paper, we will explore the literature surrounding each of these challenges and discuss potential measures that could be undertaken to mitigate these clinical and research challenges.

Development of a co-designed gamified attention bias modification app for individuals with opioid use disorder

BACKGROUND

The advances in experimental psychology in the last decade have led to a greater understanding of cognitive bias, and the investigation of cognitive bias modifications as a therapeutic option. Whilst conventionally such interventions are delivered in a laboratory, technological advances are changing the potential modes of delivery of these interventions. Whereas mobile delivery of interventions might seem to increase accessibility and encourage compliance, this might not be the case for cognitive bias modification interventions. To reduce boredom, researchers have investigated whether gamification of the task could help reduce repetitiveness, and the diminished motivation that participants had over time. In a prior review of cognitive bias modification interventions, a collaboration between academics and developers was recommended to ensure that the developed product is evidence-based. With the increased recognition of the importance of participatory action research, participants could better help conventional intervention to meet their needs.

OBJECTIVE

The aim of this article was to describe the iterative steps in the conceptualization of the co-designed gamified cognitive bias modification intervention for individuals with opioid use disorders.

METHODS AND RESULTS

A multidisciplinary team worked through the differences in the perspectives offered by healthcare professionals and patient participants, and jointly worked with a developer to conceptualize a new co-designed gamified attention bias modification intervention. The methods shared in this article could be considered and applied to future conceptualization of co-designed interventions.

Perspectives on public involvement in health research from Singapore: The potential of a supported group model of involvement

Background

Singapore is an international research hub, with an emphasis on translational clinical research. Despite growing evidence of the positive impact of public involvement (PPI) in research, it remains rare in Singapore.

Aims

To investigate Singaporean public perspectives around the rationale, role and scope for being involved in health research

To identify the potential, challenges, facilitators and strategies for implementing PPI in Singapore.

Design

Semi‐structured qualitative interviews with members of the public, analysed using thematic framework analysis.

Results

Twenty people participated. Four main themes emerged: potential benefits; challenges; facilitators; and strategies for implementation. Whilst initially unfamiliar with the concept, all interviewees recognized potential benefits for the research itself and those involved, including researchers. PPI was seen to offer opportunities for public empowerment and strengthening of relationships and understanding between the public, academics and health professionals, resulting in more impactful research. Challenges included a Singaporean culture of passive citizenship and an education system that inculcates deferential attitudes. Facilitators comprised demographic and cultural changes, including trends towards greater individual openness and community engagement. Implementation strategies included formal government policies promoting involvement and informal community‐based collaborative approaches.

Conclusion

Given the socio‐political framework in Singapore, a community‐based approach has potential to address challenges to PPI and maximize impact. Careful consideration needs to be given to issues of resource and support to enable members of the public to engage in culturally sensitive and meaningful ways that will deliver research best placed to effectively address patient needs.

Demographic predictors of wellbeing in Carers of people with psychosis: secondary analysis of trial data

BACKGROUND

Carers of people with psychosis are at a greater risk of physical and mental health problems compared to the general population. Yet, not all carers will experience a decline in health. This predicament has provided the rationale for research studies exploring what factors predict poor wellbeing in carers of people with psychosis. Our study builds on previous research by testing the predictive value of demographic variables on carer wellbeing within a single regression model.

METHODS

To achieve this aim, we conducted secondary analysis on two trial data sets that were merged and recoded for the purposes of this study.

RESULTS

Contrary to our hypotheses, only carer gender and age predicted carer wellbeing; with lower levels of carer wellbeing being associated with being female or younger (aged under 50). However, the final regression model explained only 11% of the total variance.

CONCLUSIONS

Suggestions for future research are discussed in light of the limitations inherent in secondary analysis studies. Further research is needed where sample sizes are sufficient to explore the interactive and additive impact of other predictor variables.

Impact of the fire ant pesticide AMDRO on loggerhead turtle nest productivity and seafinding orientation

Invasive fire ants prey on a variety of organisms in the southeastern USA, including the pipped eggs and hatchlings within sea turtle nests. The granular fire ant bait AMDRO® (active ingredient hydramethylnon) is currently used at some rookeries to protect nests, but no studies have been conducted to determine if the pesticide negatively impacts the eggs or the hatchlings. We examined the pesticide’s effect on loggerhead (Caretta caretta) nests at Juno Beach, Florida, USA, specifically targeting how exposure affected hatching success, hatchling emergence success, and the ability of the turtles to orient visually from the nest to the sea. Pesticide granules were placed within a 30 cm diameter circle on the sand directly above the nest during the final 5-10 days of incubation, representative of its typical application at nesting beaches. Cornmeal granules in soybean oil and untreated natural nests served as controls. AMDRO had no significant effect on hatching success or emergence success, nor did it result in any deficiencies in hatchling orientation accuracy. However, the pesticide and cornmeal control attracted other predators (Atlantic ghost crabs and avian species), in addition to fire ants, to the nest site, thus revealing the nest’s location and potentially increasing its vulnerability. Consequently, we suggest that its usage may not be beneficial at sites where predators other than ants are especially abundant.

Effectiveness of self-management interventions in young adults with type 1 and 2 diabetes: a systematic review and meta-analysis

AIM

Diabetes in young adulthood has been associated with poor outcomes. Self-management is fundamental to good diabetes care, and self-management interventions have been found to improve outcomes in older adults. We performed a systematic review and meta-analysis to assess the effectiveness of self-management interventions in young adults (aged 15-39 years) with type 1 or type 2 diabetes.

METHODS

We searched five databases and two clinical trial registries from 2003 to February 2019, without language restrictions. We included randomized controlled trials (RCTs) comparing the effectiveness of self-management interventions with usual care or enhanced usual care in young adults. Outcomes of interest included clinical outcomes, psychological health, self-care behaviours, diabetes knowledge and self-efficacy. Pairwise meta-analysis was conducted using a random effects model and quality of evidence was assessed using the Grading of Recommendations, Assessment, Development and Evaluations (GRADE) criteria. We followed Cochrane gold standard systematic review methodology and reported this systematic review according to PRISMA guidelines. The protocol was registered with PROSEPRO (CRD42018110868).

RESULTS

In total, 13 studies (1002 participants) were included. Meta-analysis showed no difference between self-management interventions and controls in post-intervention HbA_1c levels, BMI, depression, diabetes-related distress, overall self-care, diabetes knowledge and self-efficacy. Quality of evidence ranged from very low to moderate due to study limitations, inconsistency and imprecision.

CONCLUSIONS

Current self-management interventions did not improve outcomes in young adults with diabetes. Our findings, which contrast with those from systematic reviews in older adults, highlight the need for the development of more effective interventions for young adults with diabetes.

Improving access to care for people who inject drugs: Qualitative evaluation of project ITTREAT-An integrated community hepatitis C service

Achieving hepatitis C virus (HCV) elimination by 2030 requires an increased linkage to care for people who inject drugs (PWID). Project ITTREAT was established to mitigate barriers to HCV care by providing an integrated service within a local drug and alcohol treatment centre. This study aimed to explore the experiences of clients and staff involved in Project ITTREAT and assess the facilitators and barriers to a community-based HCV service. Between October 2014 and April 2016, drug and alcohol treatment attendees were interviewed using one-to-one semi-structured interviews. Drug and alcohol treatment staff took part in focus groups. All data were recorded, transcribed verbatim and analysed using thematic content analysis. Fifteen drug and alcohol treatment attendees with current/previous HCV infection were interviewed, and 15 staff members contributed across two focus groups. Drug and alcohol treatment staff and attendees reported that Project ITTREAT facilitated access to HCV care by mitigating previous negative hospital-based experiences. Other key facilitators were positive narratives around HCV care, and drug and alcohol treatment attendees being well engaged in their drug/alcohol recovery. Barriers included a lack of stability in drug and alcohol treatment attendees, negative discourse around testing/treatment and stigma associated with attending the drug and alcohol treatment to access HCV treatment in some who had successfully achieved drug rehabilitation. Our findings indicate the positive impact of an integrated and personalized community-based service delivered by a dedicated hepatitis nurse. This played a crucial role in reducing barriers to HCV care for PWID. Our work also highlights areas for future investment including non-DAT-based community services and increasing awareness of new treatments amongst this cohort.

Gamified M-Health Attention Bias Modification Intervention for Individuals with Opioid Use Disorder: Protocol for a Pilot Randomised Study

Introduction: Globally, there is an epidemic of opioid use disorders. Locally, in Singapore, there is an increase in the number of individuals abusing opioids. The advances in experimental psychology have highlighted the need to modify unconscious, automatic biases. These automatic, unconscious biases result in individuals having preferential attention to substance-related cues in their natural environment, thus leading to a slip or relapse back into their underlying addictive disorders. Prior studies have demonstrated not only the presence of robust attentional biases amongst individuals with opioid use disorder, even when maintained on methadone; and the effectiveness of bias modification amongst these individuals. There remains limited evaluation of attention bias modification amongst a treatment-seeking cohort of Asian individuals. The objective of this pilot is to ensure that the methods of the planned definitive randomized trial could be conducted. Methods and Analysis: A non-blinded pilot randomized trial will be conducted. A total of 30 participants will be randomized to receive either the conventional application or the newly designed co-designed application. In order to identify these 30 participants, 60 participants will be recruited and screened to determine if they have baseline biases. Participants will be recruited from the inpatient unit at the National Addictions Management Service (NAMS) Singapore. All participants who are enrolled into the trial will complete a baseline assessment task, and a bias modification assessment and modification task daily. They will have to complete a baseline demographic and clinical information questionnaire, as well as a cravings rating scale before and after the intervention daily. Perspectives—that of self-reported experiences—will be sought from the participants following their completion of three intervention tasks. Descriptive statistical analyses will be performed, and chi-square and ANOVA analyses will be performed. Qualitative analyses will be undertaken for the perspectives shared. Ethics and Dissemination: Ethical approval has been obtained from the National Healthcare Group’s Domain Specific Research Board (DSRB) (approval number that of 2019/00934). The findings arising from this study will be disseminated by means of conferences and publications.

Barriers to recruiting and retaining psychosis carers: a case study on the lessons learned from the Caring for Caregivers (C4C) trial

Objective

Carers play an important role within the UK mental health system. Those carers who support persons with psychosis can experience a reduction in their own physical and mental health. As part of the Caring for Caregivers (C4C) trial, we piloted a writing intervention (Positive Written Disclosure) that has been shown to improve wellbeing in other populations. Although we reached our recruitment target, we encountered several barriers that made recruitment slower than anticipated. This paper synthesises the process data collected during the C4C trial that relates to the barriers to recruiting and retaining psychosis carers.

Results

We encountered four main carer-specific barriers to the recruitment and retention of participants in our study. These were: (1) poor relationship with mental health clinicians, (2) conflicting with the care recipient’s (CR) needs, (3) lack of spare time, and (4) lack of services for mental health carers. The interventions to assist carers need to be informed by robust evidence and this requires trials that reach their recruitment targets. By sharing our practical experiences other researchers and clinicians can modify their practices to minimise recruitment difficulties and delay.

Making Sense of Negative Findings from Mobile Attention Bias Modification Interventions for Individuals with Addictive Disorders: Quantitative Feasibility Study

Background

Advances in experimental psychology have led to a better understanding of unconscious, automatic processes that result in individuals relapsing into their substance-using habits. While some reviews have demonstrated the effectiveness of bias retraining of these unconscious biases, there have been other reviews that have highlighted that bias retraining is not always effective. Other studies have revealed there was no baseline biases among some participants. An examination of mobile bias retraining interventions has also revealed mixed results, with some reporting effectiveness and others null findings. A recent feasibility and acceptability study, done by the authors, revealed that 53% of participants have had no baseline biases and 21% of those with positive baseline biases did not have a positive change in magnitude following intervention.

Objective

The aim of this paper was to explore potential variables (demographic and clinical) that could account for the negative baseline biases in the prior feasibility and acceptability study, and to discuss some of the factors that could account for the absence of baseline biases. We also explored potential reasons for why there was no reduction in the magnitude of attentional biases among individuals with baseline biases.

Methods

Participants who were in the rehabilitation phase of their treatment were invited to participate. During the study they had to complete a set of baseline questionnaires, and on each day that they were on the ward they had to complete an attention bias assessment and modification task and rate their cravings using a visual analogue scale. Attention bias was deemed to be present if individuals had a positive score.

Results

In our study, 53% (16/30) of individuals did not present with baseline attentional biases, and among those with positive baseline biases a total of 21% (3/14) of participants did not have a reduction in the overall magnitude of attentional biases. Chi-square analyses undertaken to compare the demographic characteristics of participants with and without baseline biases did not reveal any significant findings. However, with respect to clinical characteristics, those who had positive baseline biases had experimented with more substances.

Conclusions

Our study is one of the first to have explored negative findings in attention bias modification interventions for individuals with addictive disorders. We postulate that several factors could account for the absence of baseline biases and there being no changes following bias retraining. Future research ought to take into consideration these factors.

Co-designing a Mobile Gamified Attention Bias Modification Intervention for Substance Use Disorders: Participatory Research Study

Background

Advances in experimental psychology have highlighted the need to modify underlying automatic cognitive biases, such as attentional biases. The effectiveness of bias modification has been well studied for substance use disorders. With recent advances in technology, it is now possible to work outside the laboratory with Web-based and mobile-based attention bias interventions. Gamification technologies might also help diminish the repetitiveness of the task and increase the intrinsic motivation to train. The inconsistent findings of the impact of gaming on the effectiveness of mobile interventions call for further work to better understand the needs of patients (users) and health care professionals.

Objective

The aim of this study was to involve patients, together with health care professionals, in the design of a gamified mobile attention bias modification intervention for substance use disorders.

Methods

The participatory design research method adopted is that of a user-oriented design approach in the form of a future workshop. In the first phase of the workshop, participants shared their critique of an attention bias modification intervention. In the second phase of the workshop, participants were asked to brainstorm features. Participants were also shown gamification approaches and asked to consider if gaming elements could enhance the existing app. In the last phase, participants were asked to sketch a new prototype.

Results

Three co-design workshops were conducted with health care professionals, inpatients, and outpatients. There were 20 participants, consisting of 10 health care professionals and 10 patients. When asked to identify the limitations in the existing app, common issues identified were those of the design, visual probe task, and the included images. Outpatients were also concerned with the safety of administration of the intervention. In the brainstorming sessions, health care professionals made recommendations as to how the stimulus, the mechanism of responding, and the presentation of the scores could be enhanced. Inpatient participants recommended the addition of functionalities, such as information on the harms associated with the substance use, and for there to be enhancements in the design, images, and task. Outpatient participants perceived a need to improve the images and presentation of the results and recommended the inclusion of gaming features. There were differences in opinion on the inclusion of gaming features, as only health care professionals endorsed their inclusion. In the last phase of the workshop, participants were tasked with the conceptualization of prototypes, and the commonality in the design was for a gradual shortening of the interval for stimulus/image presentation.

Conclusions

The results from this research will guide the development of an app that meets the specific needs of patients and is still based on a pre-existing validated task paradigm.  

Attitudes and perception of influenza vaccines among older people in Singapore: A qualitative study

Background

Despite recommendations for influenza vaccination of people aged 65 and above, uptake rate of influenza vaccines remains low.

This study aims to understand barriers and motivators behind older adult’s decision on influenza vaccination.

Methods

Face to face interviews with participants aged 65 and above were conducted and audio recorded in Geylang polyclinic in Singapore. Thematic content analysis was used to organise the data.

Results

15 older adults were interviewed, aged between 66 and 85 years old. 6 were vaccine refusers, 3 defaulters and 6 acceptors.

A perceived lack of vulnerability, fear of side effects, and trivialisation of influenza were common reasons for not taking the vaccine. Encouragement from family and friends, travel and previous positive vaccination experiences were motivators for getting vaccinated. Healthcare workers played a role in influencing many of the participants’ decision-making. Common misconceptions included vaccines considered as necessary only before travel and as a cure rather than prevention. Most participants exhibited ambivalence, giving reasons both for and against vaccine uptake.

Discussion

Most older adults do not perceive influenza as a potentially serious disease nor trust in influenza vaccines’ efficacy. Misconceptions played a significant role in vaccine decline. Novel findings include the importance of the family unit in decision making, prioritization of chronic health problems over vaccination and misconception that vaccines are only needed when travelling out of country. Healthcare workers and family members appear to be important influencers in the decision making of older adults and should be actively engaged in future health promotion initiatives.

Researchers' perspectives on public involvement in health research in Singapore: The argument for a community-based approach

Background

Singapore is becoming a world‐class research hub, promoting the advancement of patient care through translational clinical research. Despite growing evidence internationally of the positive impact of public involvement (PPI), in Singapore PPI remains unusual beyond patient participation as subjects in studies.

Objective

To explore health researchers' understandings of the principles, role and scope of PPI, and to identify barriers and opportunities for implementation in Singapore.

Design

Semi‐structured qualitative interviews between April and July 2018. Data were analysed using thematic framework analysis.

Results

Whilst most participants (n = 20) expressed a lack of experience of PPI, the interview process provided an opportunity for reflection through which it emerged as a beneficial strategy. Interviewees highlighted both utilitarian and ethical reasons for implementing PPI, particularly around increasing the relevance and efficiency of research. In addition to those challenges to PPI documented in the existing literature, participants highlighted others specific to the Singaporean context that make PPI at an individual level unlikely to be successful, including the socio‐political environment and prevailing social and professional hierarchies. They also identified asset‐based strategies to overcome these, in particular, a more community‐oriented approach.

Conclusion

The cultural reluctance of individuals to question perceived authority figures such as researchers may be overcome by adopting an approach to PPI that is closer to family and local community values, and which facilitates patients and the public collectively engaging in research. Further work is needed to explore the views of patients and the public in Singapore, and the implications for other Asian communities.

"At a loss of what to do": a qualitative analysis of parents' online discussion forums about their administration of asthma inhalers to their young children

Objective: The difficulties adults have using inhaler devices is well documented but much less is known about how parents administer inhaler devices to young children and the difficulties experienced. The purpose of this article is to explore the underlying concepts and practical issues that parents encounter in administering inhaled asthma medications to their young children.Methods: This is a qualitative study using applied thematic analysis on parental written discourses from asynchronous online discussion forums on the topic of administration and use of asthma inhaler devices to young children.Results: "At a loss of what to do" summarizes the experiences parents described when administering inhaler devices to their young children. Parents describe the problems, the situations, the emotions, the decisions, and the confusion they face. They struggle with their child's resistance and the associated conflict, describing their own and their child's distress. Results highlight the coping strategies used in administration, how parents decide whether to use coercive measures or not, their help-seeking endeavors, together with the assurance they give to themselves and others after administration.Conclusion: The online discussions highlight parents' distress, lack of preparedness, and understanding of administering inhaler devices to young children. While the prevalence of the problem cannot be estimated from our data, it illustrates a need for some healthcare professionals to review their own knowledge and skills in administration of inhaled medication to younger patients, and their provision of patient and family centered care.

Search strategies to identify observational studies in MEDLINE and Embase

BACKGROUND

Systematic reviews are essential for decision-making. Systematic reviews on observational studies help answer research questions on aetiology, risk, prognosis, and frequency of rare outcomes or complications. However, identifying observational studies as part of systematic reviews efficiently is challenging due to poor and inconsistent indexing in literature databases. Search strategies that include a methodological filter focusing on study design of observational studies might be useful for improving the precision of the search performance.

OBJECTIVES

To assess the sensitivity and precision of a search strategy with a methodological filter to identify observational studies in MEDLINE and Embase.

SEARCH METHODS

We searched MEDLINE (1946 to April 2018), Embase (1974 to April 2018), CINAHL (1937 to April 2018), the Cochrane Library (1992 to April 2018), Google Scholar and Open Grey in April 2018, and scanned reference lists of articles.

SELECTION CRITERIA

Studies using a relative recall approach, i.e. comparing sensitivity or precision of a search strategy containing a methodological filter to identify observational studies in MEDLINE and Embase against a reference standard, or studies that compared two or more methodological filters.

DATA COLLECTION AND ANALYSIS

Two review authors independently screened articles, extracted relevant information and assessed the quality of the search strategies using the InterTASC Information Specialists' Sub-Group (ISSG) Search Filter Appraisal Checklist.

MAIN RESULTS

We identified two eligible studies reporting 18 methodological filters. All methodological filters in these two studies were developed using terms from the reference standard records.The first study evaluated six filters for retrieving observational studies of surgical interventions. The study reported on six filters: one Precision Terms Filter (comprising terms with higher precision while maximum sensitivity was maintained) and one Specificity Terms Filter (comprising terms with higher specificity while maximum sensitivity was maintained), both of which were adapted for MEDLINE, for Embase, and for combined MEDLINE/Embase searches. The study reported one reference standard consisting of 217 articles from one systematic review of which 83.9% of the included studies were case seriesThe second study reported on 12 filters for retrieving comparative non-randomised studies (cNRSs) including cohort, case-control, and cross-sectional studies. This study reported on 12 filters using four different approaches: Fixed method A (comprising of a fixed set of controlled vocabulary (CV) words), Fixed method B (comprising a fixed set of CV words and text words (TW)), Progressive method (CV) (a random choice of study design-related CV terms), and Progressive method (CV or TW) (a random choice of study design-related CV terms, and title and abstracts-based TWs). The study reported four reference standards consisting of 89 cNRSs from four systematic reviews.The six methodological filters developed from the first study reported sensitivity of 99.5% to 100% and precision of 16.7% to 21.1%. The Specificity Terms Filter for combined MEDLINE/Embase was preferred because it had higher precision and equal sensitivity to the Precision Terms Filter. The 12 filters from the second study reported lower sensitivity (48% to 100%) and much lower precision (0.09% to 4.47%). The Progressive method (CV or TW) had the highest sensitivity.There were methodological limitations in both included studies. The first study used one surgical intervention-focused systematic review thus limiting the generalizability of findings. The second study used four systematic reviews but with less than 100 studies. The external validation was performed only on Specificity Terms Filter from the first study Both studies were published 10 years ago and labelling and indexing of observational studies has changed since then.

AUTHORS' CONCLUSIONS

We found 18 methodological filters across two eligible studies. Search strategies from the first study had higher sensitivity and precision, underwent external validation and targeted observational studies. Search strategies from the second study had lower sensitivity and precision, focused on cNRSs, and were not validated externally. Given this limited and heterogeneous evidence, and its methodological limitations, further research and better indexation are needed.

CD28null pro-atherogenic CD4 T-cells explain the link between CMV infection and an increased risk of cardiovascular death

An increased risk of cardiovascular death in Cytomegalovirus (CMV)-infected individuals remains unexplained, although it might partly result from the fact that CMV infection is closely associated with the accumulation of CD28^null T-cells, in particular CD28^null CD4 T-cells. These cells can directly damage endothelium and precipitate cardiovascular events. However, the current paradigm holds that the accumulation of CD28^null T-cells is a normal consequence of aging, whereas the link between these T-cell populations and CMV infection is explained by the increased prevalence of this infection in older people. Resolving whether CMV infection or aging triggers CD28^null T-cell expansions is of critical importance because, unlike aging, CMV infection can be treated.

Methods: We used multi-color flow-cytometry, antigen-specific activation assays, and HLA-typing to dissect the contributions of CMV infection and aging to the accumulation of CD28^null CD4 and CD8 T-cells in CMV+ and CMV- individuals aged 19 to 94 years. Linear/logistic regression was used to test the effect of sex, age, CMV infection, and HLA-type on CD28^null T-cell frequencies.

Results: The median frequencies of CD28^null CD4 T-cells and CD28^null CD8 T-cells were >12-fold (p=0.000) but only approximately 2-fold higher (p=0.000), respectively, in CMV+ (n=136) compared with CMV- individuals (n=106). The effect of CMV infection on these T-cell subsets was confirmed by linear regression. Unexpectedly, aging contributed only marginally to an increase in CD28^null T-cell frequencies, and only in CMV+ individuals. Interestingly, the presence of HLA-DRB1*0301 led to an approximately 9-fold reduction of the risk of having CD28^null CD4 T-cell expansions (OR=0.108, p=0.003). Over 75% of CMV-reactive CD4 T-cells were CD28^null.

Conclusion: CMV infection and HLA type are major risk factors for CD28^null CD4 T-cell-associated cardiovascular pathology. Increased numbers of CD28^null CD8 T-cells are also associated with CMV infection, but to a lesser extent. Aging, however, makes only a negligible contribution to the expansion of these T-cell subsets, and only in the presence of CMV infection. Our results open up new avenues for risk assessment, prevention, and treatment.

Recent Advances in Attention Bias Modification for Substance Addictions

Research on attentional bias modification has increased since 2014. A recent meta-analysis demonstrates evidence for bias modification for substance disorders, including alcohol and tobacco use disorders. Several pharmacological trials have shown that pharmacological agents can attenuate and modify such attentional bias. The pharmacological trials that have appeared to date have produced mixed results, which has clinical implications. Developments in Internet and mobile technologies have transformed how attention bias modification is currently being achieved. There remains great potential for further research that examines the efficacy of technology-aided attention bias interventions.

Predicting dementia from primary care records: A systematic review and meta-analysis

INTRODUCTION

Possible dementia is usually identified in primary care by general practitioners (GPs) who refer to specialists for diagnosis. Only two-thirds of dementia cases are currently recorded in primary care, so increasing the proportion of cases diagnosed is a strategic priority for the UK and internationally. Variables in the primary care record may indicate risk of developing dementia, and could be combined in a predictive model to help find patients who are missing a diagnosis. We conducted a meta-analysis to identify clinical entities with potential for use in such a predictive model for dementia in primary care.

METHODS AND FINDINGS

We conducted a systematic search in PubMed, Web of Science and primary care database bibliographies. We included cohort or case-control studies which used routinely collected primary care data, to measure the association between any clinical entity and dementia. Meta-analyses were performed to pool odds ratios. A sensitivity analysis assessed the impact of non-independence of cases between studies. From a sift of 3836 papers, 20 studies, all European, were eligible for inclusion, comprising >1 million patients. 75 clinical entities were assessed as risk factors for all cause dementia, Alzheimer's (AD) and Vascular dementia (VaD). Data included were unexpectedly heterogeneous, and assumptions were made about definitions of clinical entities and timing as these were not all well described. Meta-analysis showed that neuropsychiatric symptoms including depression, anxiety, and seizures, cognitive symptoms, and history of stroke, were positively associated with dementia. Cardiovascular risk factors such as hypertension, heart disease, dyslipidaemia and diabetes were positively associated with VaD and negatively with AD. Sensitivity analyses showed similar results.

CONCLUSIONS

These findings are of potential value in guiding feature selection for a risk prediction tool for dementia in primary care. Limitations include findings being UK-focussed. Further predictive entities ascertainable from primary care data, such as changes in consulting patterns, were absent from the literature and should also be explored in future studies.

Cognitive Biases in Cannabis, Opioid, and Stimulant Disorders: A Systematic Review

Background: Opiates, cannabis, and stimulants are highly abused and are prevalent disorders. Psychological interventions are crucial given that they help individuals maintain abstinence following a lapse or relapse into substance use. The dual-process theory has posited that while the repeated use of a substance leads to increased automatic processing and increased automatic tendencies to approach substance-specific cues, in addition to the inhibition of other normal cognitive processes. Prior reviews are limited, as they failed to include trials involving participants with these prevalent addictive disorders or have not reviewed the published literature extensively. Objectives: The primary aim of this review is to synthesize the evidence for cognitive biases in opioid use, cannabis use, and stimulant use disorders. The secondary aim of the review is to determine if cognitive bias could be consistently detected using the different methods. Lastly, this review will narratively synthesize the evidence of possible associations between cognitive biases and other addiction-related outcomes. Methods: A search was conducted from November 2017 to January 2018 on PubMed, MEDLINE, Embase, PsycINFO, Science Direct, Cochrane Central, and Scopus. Articles were included if participants had a primary diagnosis of opioid use, cannabis use, or stimulant use disorder. The selection process of the articles was in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analysis guidelines. A qualitative synthesis was undertaken. Results: A total of 38 studies were identified. The main finding is the evidence that cognitive biases are present in the 38 studies identified, except for a single study on opioid use and stimulant use disorders. Cognitive biases were reported despite a variety of different methods being utilized. Synthesis of secondary outcome was not feasible, due to the varied outcomes reported. Conclusions: Cognitive biases have been consistently observed in opioid use, cannabis use, and stimulant use disorders, despite a range of assessment tools being utilized in the assessment for these biases.

Caring for Caregivers (C4C): study protocol for a pilot feasibility randomised control trial of Positive Written Disclosure for older adult caregivers of people with psychosis

Background

The caregivers of people who experience psychosis are themselves at risk of developing physical and mental health problems. This risk is increased for older adult caregivers who also have to manage the lifestyle and health changes associated with ageing. As a consequence, older adult caregivers are in particular need of support; we propose a Written Emotional Disclosure (WED) intervention, called Positive Written Disclosure (PWD).

Methods/design

This is a pilot randomised controlled trial of PWD compared to a neutral writing control and a no writing condition. We aim to recruit 60 participants, 20 in each arm. This study will utilise a mixed-methods approach and collect quantitative (questionnaires) and qualitative (interviews) data. Quantitative data will be collected at baseline and 1, 3, and 6 months post baseline. Participants who complete a writing task (PWD or neutral writing control) will be invited to complete an exit interview to discuss their experiences of the intervention and study. The study is supported by a patient and public involvement group.

Discussion

The results of this trial will determine whether a definitive trial is justified. If so, the quantitative and qualitative findings will be used to refine the intervention and study protocols.

Barriers to Antenatal Care in an Urban Community in the Gambia: An In-depth Qualitative Interview Study

This qualitative study investigated the barriers to obtaining access to antenatal care in a small, urban government-supported health centre in the Gambia. It thus addresses an important issue related to maternal health and the prevention of maternal deaths. In-depth interviews were conducted with 25 pregnant women, 13 healthcare workers and 9 male partners. Three areas were identified for study: recognition and acknowledgment of pregnancy, recognition of the need for care and practical barriers to attendance. Intentional concealment of early pregnancy was common to avoid adverse social consequences or for fear that malign interventions would cause a miscarriage. In the absence of symptoms many women considered it unnecessary to attend the antenatal clinic until well into the second trimester. Practical barriers to attendance included conflicting domestic demands and the attitude of some healthcare workers. Access to antenatal care in the Gambia throughout pregnancy should be considered in a stepwise fashion and barriers to care were identified at each stage. Interviews with male partners and health workers highlighted their key role.

Feasibility and Participant Experiences of a Written Emotional Disclosure Intervention for Parental Caregivers of People with Psychosis

Caregivers are at increased risk of poor health but often cannot engage with health care because of practical constraints. Writing therapies such as written emotional disclosure (WED) might represent an accessible therapy for this population. This study aimed to determine whether WED is a suitable therapy for caregivers of people with psychosis. Data were collected from a feasibility trial comparing WED with a neutral writing task. Twenty four participants completed writing tasks; the content was analysed using the Linguistic Inquiry Word Count (LIWC) programme. Twenty one participants provided feedback about the writing task, and data were analysed using Burnard's thematic content analysis. WED was feasible to implement in caregivers of people with psychosis. All participants ascribed benefit to writing tasks, the majority describing a cathartic effect, enjoying time to oneself or distraction from caregiving. Quantitative comparison indicated differences in emotional content between intervention and control writing. However, qualitative analysis showed that control participants found it challenging to write neutrally, the majority citing the care-recipient in their writing. Community-based WED is a feasible therapy for caregivers of people with psychosis. The need for refinement of the control writing task for use in caregivers is discussed.

Nonpharmacological interventions aimed at modifying health and behavioural outcomes for adults with asthma: a critical review

Evidence suggests that living with asthma is linked with psychological and behavioural factors including self-management and treatment adherence, and therefore, there is a reasonable hypothesis that nonpharmacological treatments may improve health outcomes in people living with this condition. A systematic review of randomized controlled trials (RCTs) of nonpharmacological interventions for adults with asthma was designed. Databases searched included The Cochrane Airways Group Register of trials, CENTRAL and Psychinfo. The literature search was conducted until May 2014. Twenty-three studies met the inclusion criteria and were organized into four groups: relaxation-based therapies (n = 9); mindfulness (n = 1), biofeedback techniques (n = 3); cognitive behavioural therapies (CBT) (n = 5); and multicomponent interventions (n = 5). A variety of outcome measures were used, even when trials belonged to the same grouping, which limited the ability to conduct meaningful meta-analyses. Deficiencies in the current evidence base, notably trial heterogeneity, means that application to clinical practice is limited and clear guidelines regarding the use of nonpharmacological therapies in asthma is limited. Relaxation and CBT, however, appear to have a consistent positive effect on asthma-related quality of life and some psychological outcomes, and lung function (relaxation only). Future trials should be informed by previous work to harmonize the interventions under study and outcome measures used to determine their effectiveness; only then will meaningful meta-analyses inform clinical practice.

Ultrasound-guided selective block of the anterior branch of the obturator nerve for transurethral resection of bladder tumour

Introduction:

Bladder perforation is a serious complication of transurethral resection of bladder tumour (TURBT). One of the risk factors is an “obturator jerk”, caused by stimulation of the obturator nerve, causing powerful adduction of the leg. As almost half of all bladder tumours are located on the lateral wall and 55–100% of resections on the lateral wall can result in obturator jerk; this is not an insignificant risk.

Patients:

We have introduced regional anaesthetic nerve block of the anterior branch of the obturator nerve in patients with known lateral wall tumours undergoing TURBT.

Methods:

This procedure was performed by two consultant anaesthetists in our unit. Patients are positioned supine with the leg slightly abducted and laterally rotated. Ultrasound (US) is used to identify the anterior branch of the adductor longus, brevis and magnus muscles in the medial thigh, 2–3 cm inferior to the inguinal crease. The obturator nerve is situated in the plane between adductor longus and adductor brevis, medial to pectineus. An insulated needle is passed under US guidance and a nerve stimulator is used to elicit a twitch. Levobupivicaine is used to infiltrate the anterior branch of the obturator nerve to achieve motor block of the adductor brevis, adductor longus and gracillis muscles. TURBT is then performed.

Results:

This prospective pilot series includes 18 TURBT procedures. These were performed under spinal anaesthetic ( n=16) or general anaesthetic without muscle relaxant ( n=2). Tumours characteristics were; large flat areas of re-resection ( n=5), flat bladder lesions ( n=1) or exophytic lesions ( n=12). There were no incidences of obturator jerk observed during TURBT (0/18). There were no intra or post-operative complications.

Conclusion:

This simple technique can be easily applied to patients undergoing TURBT. Larger studies are required, but our series supports the use of this technique to reduce obturator jerk, which is an important risk factors for bladder perforation.

Extracting information from the text of electronic medical records to improve case detection: a systematic review

BACKGROUND

Electronic medical records (EMRs) are revolutionizing health-related research. One key issue for study quality is the accurate identification of patients with the condition of interest. Information in EMRs can be entered as structured codes or unstructured free text. The majority of research studies have used only coded parts of EMRs for case-detection, which may bias findings, miss cases, and reduce study quality. This review examines whether incorporating information from text into case-detection algorithms can improve research quality.

METHODS

A systematic search returned 9659 papers, 67 of which reported on the extraction of information from free text of EMRs with the stated purpose of detecting cases of a named clinical condition. Methods for extracting information from text and the technical accuracy of case-detection algorithms were reviewed.

RESULTS

Studies mainly used US hospital-based EMRs, and extracted information from text for 41 conditions using keyword searches, rule-based algorithms, and machine learning methods. There was no clear difference in case-detection algorithm accuracy between rule-based and machine learning methods of extraction. Inclusion of information from text resulted in a significant improvement in algorithm sensitivity and area under the receiver operating characteristic in comparison to codes alone (median sensitivity 78% (codes + text) vs 62% (codes), P = .03; median area under the receiver operating characteristic 95% (codes + text) vs 88% (codes), P = .025).

CONCLUSIONS

Text in EMRs is accessible, especially with open source information extraction algorithms, and significantly improves case detection when combined with codes. More harmonization of reporting within EMR studies is needed, particularly standardized reporting of algorithm accuracy metrics like positive predictive value (precision) and sensitivity (recall).

A qualitative study of the allergy testing experiences, views and preferences of adult patients

Background

Patients can be tested for IgE sensitivities with in vivo or in vitro testing, but patients’ experiences of different allergy test modalities have not been studied. The objective of this study was to investigate adult patients’ experiences, views and preferences for allergy testing, exploring skin prick testing and allergen-specific IgE testing.

Methods

A qualitative study of adults attending out-patients for investigation of a suspected allergy. A purposive, convenience sample identified participants and semi-structured interviews were conducted, face to face or by telephone. Interviews were recorded and transcribed verbatim. Thematic content analysis was used to explore patients’ experiences.

Results

23 patients were interviewed. The characteristics of skin prick tests particularly valued were the immediacy and visibility of results, which enabled testing and interpretation to be achieved within a single clinic appointment. In vitro testing offered patients simplicity and procedural speed, necessitating only a single puncture site, and was perceived to be a superior test as it was conducted in a laboratory.

Conclusions

The patient preferred method of allergy testing was skin prick testing rather than in vitro allergen specific IgE testing. However, most patients were accepting of either testing modality because their desire to confirm or exclude an allergic trigger overrode any perceived disadvantages of the test method.

Trial registration

Not applicable as study descriptive and qualitative.

Dissemination of definitions and concepts of allergic and hypersensitivity conditions

BACKGROUND

Allergy and hypersensitivity can affect people of any age and manifest with problems in a range of organ systems. Moreover, they can have a significant impact on the quality of life of patients and their families. Although once rare, there is presently an epidemic of allergic disorders with associated considerable societal consequences. Our understanding of the pathophysiology of these disorders has changed substantially over the last 20 years. In the light of these developments, the Joint Allergy Academies have made concerted efforts to ensure that these are reflected in the current definitions and concepts used in clinical allergy and to ensure these are reflected in the forthcoming International Classification of Diseases-11 (ICD-11).

OBJECTIVE

In this review, we seek to provide an update on the current definitions and concepts in relation to allergic disorders.

RESULTS

Once the new section has been built in the ICD-11 to address allergic and hypersensitivity conditions, we have been moving actions to try to support awareness by disseminating updated concepts in the field. Aligned with the ICD and the WAO philosophy of being global, this document presents fundamental and broad allergy concepts to strengthen the understanding by different health professionals worldwide, besides to support the formation of in training students.

CONCLUSION

This current review intends to be accepted and used universally by all health professionals involved in diseases' classification and coding and, therefore, contribute to improve care and outcomes in this increasing sub-section of the world's population.

A systematic review of the effectiveness of interventions using the Common Sense Self-Regulatory Model to improve adherence behaviours

This systematic review assessed the effectiveness of the Common Sense Self-Regulatory Model in the design of interventions to improve adherence behaviours. Of nine eligible studies, six reported improvements in adherence behaviours and three showed moderate to large effects on return to work and lifestyle recommendations. Four studies stated how Common Sense Self-Regulatory Model constructs were addressed in the intervention and five measured illness perceptions as outcomes. Evidence was found for targeting cure/control perceptions in studies aimed at improving adherence behaviours. Future studies need to measure illness perceptions pre- and post-intervention to enable mediational analyses to assess the effect of Common Sense Self-Regulatory Model interventions on improving health outcomes.

An emerging zoonotic clone in the Netherlands provides clues to virulence and zoonotic potential of Streptococcus suis

Streptococcus suis is a zoonotic swine pathogen and a major public health concern in Asia, where it emerged as an important cause of bacterial meningitis in adults. While associated with food-borne transmission in Asia, zoonotic S. suis infections are mainly occupational hazards elsewhere. To identify genomic differences that can explain zoonotic potential, we compared whole genomes of 98 S. suis isolates from human patients and pigs with invasive disease in the Netherlands, and validated our observations with 18 complete and publicly available sequences. Zoonotic isolates have smaller genomes than non-zoonotic isolates, but contain more virulence factors. We identified a zoonotic S. suis clone that diverged from a non-zoonotic clone by means of gene loss, a capsule switch, and acquisition of a two-component signalling system in the late 19th century, when foreign pig breeds were introduced. Our results indicate that zoonotic potential of S. suis results from gene loss, recombination and horizontal gene transfer events.

Head injury follow-up: is the Sickness Impact Profile a useful clinical tool?

Twenty adults who had sustained severe head injury completed the Sickness Impact Profile questionnaire and the Leeds Scales of anxiety and depression five or more years after the injury. All but one of the subjects reported persistent problems, and all but eight were either unemployed or working in a reduced capacity. Patients' reports were supported by those of relatives. It is argued that both patients and relatives should be followed up regularly, for more than just the first year, and that the Sickness Impact Profile would serve this purpose well. The advantages and limitations of this instrument for clinical use are discussed.

The Validation of a Case-Based, Cumulative Assessment and Progressions Examination

OBJECTIVE

To assess content and criterion validity, as well as reliability of an internally developed, case-based, cumulative, high-stakes third-year Annual Student Assessment and Progression Examination (P3 ASAP Exam).

METHODS

Content validity was assessed through the writing-reviewing process. Criterion validity was assessed by comparing student scores on the P3 ASAP Exam with the nationally validated Pharmacy Curriculum Outcomes Assessment (PCOA). Reliability was assessed with psychometric analysis comparing student performance over four years.

RESULTS

The P3 ASAP Exam showed content validity through representation of didactic courses and professional outcomes. Similar scores on the P3 ASAP Exam and PCOA with Pearson correlation coefficient established criterion validity. Consistent student performance using Kuder-Richardson coefficient (KR-20) since 2012 reflected reliability of the examination.

CONCLUSION

Pharmacy schools can implement internally developed, high-stakes, cumulative progression examinations that are valid and reliable using a robust writing-reviewing process and psychometric analyses.
