What are the barriers to implementing national antimicrobial resistance action plans? A novel mixed-methods policy analysis in Pakistan

Despite political commitment to address antimicrobial resistance (AMR), countries are facing challenges to implementing policies to reduce inappropriate use of antibiotics. Critical factors to the success of policy implementation in low- and middle-income countries (LMIC), such as capacity for enforcement, contestation by influential stakeholders and financial interests, have been insufficiently considered. Using Pakistan as a case study representing a populous country with extremely high antibiotic usage, we identified 195 actors who affect policies on antibiotic use in humans and animals through a snowballing process and interviewed 48 of these who were nominated as most influential. We used a novel card game-based methodology to investigate policy actors' support for implementation of different regulatory approaches addressing actions of frontline healthcare providers and antibiotic producers across the One Health spectrum. We found that there was only widespread support for implementing hard regulations (prohibiting certain actions) against antibiotic suppliers with little power-such as unqualified/informal healthcare providers and animal feed producers-but not to target more powerful groups such as doctors, farmers and pharmaceutical companies. Policy actors had limited knowledge to develop implementation plans to address inappropriate use of antibiotics in animals, even though this was recognized as a critical driver of AMR. Our results indicate that local political and economic dynamics may be more salient to policy actors influencing implementation of AMR national action plans than solutions presented in global guidelines that rely on implementation of hard regulations. This highlights a disconnect between AMR action plans and the local contexts where implementation takes place. Thus if the global strategies to tackle AMR are to become implementable policies in LMIC, they will need greater appreciation of the power dynamics and systemic constraints that relate to many of the strategies proposed.

Higher vs lower doses of dexamethasone in patients with COVID-19 and severe hypoxia (COVID STEROID 2) trial: Protocol and statistical analysis plan

Background

The coronavirus disease 2019 (COVID‐19) pandemic has resulted in millions of deaths and overburdened healthcare systems worldwide. Systemic low‐dose corticosteroids have proven clinical benefit in patients with severe COVID‐19. Higher doses of corticosteroids are used in other inflammatory lung diseases and may offer additional clinical benefits in COVID‐19. At present, the balance between benefits and harms of higher vs. lower doses of corticosteroids for patients with COVID‐19 is unclear.

Methods

The COVID STEROID 2 trial is an investigator‐initiated, international, parallel‐grouped, blinded, centrally randomised and stratified clinical trial assessing higher (12 mg) vs. lower (6 mg) doses of dexamethasone for adults with COVID‐19 and severe hypoxia. We plan to enrol 1,000 patients in Denmark, Sweden, Switzerland and India. The primary outcome is days alive without life support (invasive mechanical ventilation, circulatory support or renal replacement therapy) at day 28. Secondary outcomes include serious adverse reactions at day 28; all‐cause mortality at day 28, 90 and 180; days alive without life support at day 90; days alive and out of hospital at day 90; and health‐related quality of life at day 180. The primary outcome will be analysed using the Kryger Jensen and Lange test adjusted for stratification variables and reported as adjusted mean differences and median differences. The full statistical analysis plan is outlined in this protocol.

Discussion

The COVID STEROID 2 trial will provide evidence on the optimal dosing of systemic corticosteroids for COVID‐19 patients with severe hypoxia with important implications for patients, their relatives and society.

Improving National Intelligence for Public Health Preparedness: a methodological approach to finding local multi-sector indicators for health security

The COVID-19 epidemic is the latest evidence of critical gaps in our collective ability to monitor country-level preparedness for health emergencies. The global frameworks that exist to strengthen core public health capacities lack coverage of several preparedness domains and do not provide mechanisms to interface with local intelligence. We designed and piloted a process, in collaboration with three National Public Health Institutes (NPHIs) in Ethiopia, Nigeria and Pakistan, to identify potential preparedness indicators that exist in a myriad of frameworks and tools in varying local institutions. Following a desk-based systematic search and expert consultations, indicators were extracted from existing national and subnational health security-relevant frameworks and prioritised in a multi-stakeholder two-round Delphi process. Eighty-six indicators in Ethiopia, 87 indicators in Nigeria and 51 indicators in Pakistan were assessed to be valid, relevant and feasible. From these, 14–16 indicators were prioritised in each of the three countries for consideration in monitoring and evaluation tools. Priority indicators consistently included private sector metrics, subnational capacities, availability and capacity for electronic surveillance, measures of timeliness for routine reporting, data quality scores and data related to internally displaced persons and returnees. NPHIs play an increasingly central role in health security and must have access to data needed to identify and respond rapidly to public health threats. Collecting and collating local sources of information may prove essential to addressing gaps; it is a necessary step towards improving preparedness and strengthening international health regulations compliance.

Mitigating the impact of COVID-19 on tuberculosis and HIV services: A cross-sectional survey of 669 health professionals in 64 low and middle-income countries

Objective

The experiences of frontline healthcare professionals are essential in identifying strategies to mitigate the disruption to healthcare services caused by the COVID-19 pandemic.

Methods

We conducted a cross-sectional study of TB and HIV professionals in low and middle-income countries (LMIC). Between May 12 and August 6, 2020, we collected qualitative and quantitative data using an online survey in 11 languages. We used descriptive statistics and thematic analysis to analyse responses.

Findings

669 respondents from 64 countries completed the survey. Over 40% stated that it was either impossible or much harder for TB and HIV patients to reach healthcare facilities since COVID-19. The most common barriers reported to affect patients were: fear of getting infected with SARS-CoV-2, transport disruptions and movement restrictions. 37% and 28% of responses about TB and HIV stated that healthcare provider access to facilities was also severely impacted. Strategies to address reduced transport needs and costs–including proactive coordination between the health and transport sector and cards that facilitate lower cost or easier travel—were presented in qualitative responses. Access to non-medical support for patients, such as food supplementation or counselling, was severely disrupted according to 36% and 31% of HIV and TB respondents respectively; qualitative data suggested that the need for such services was exacerbated.

Conclusion

Patients and healthcare providers across numerous LMIC faced substantial challenges in accessing healthcare facilities, and non-medical support for patients was particularly impacted. Synthesising recommendations of frontline professionals should be prioritised for informing policymakers and healthcare service delivery organisations.

Using critical information to strengthen pandemic preparedness: the role of national public health agencies

COVID-19 has demonstrated that most countries' public health systems and capacities are insufficiently prepared to prevent a localised infectious disease outbreak from spreading. Strengthening national preparedness requires National Public Health Institutes (NPHIs), or their equivalent, to overcome practical challenges affecting timely access to, and use of, data that is critical to preparedness. Our situational analysis in collaboration with NPHIs in three countries-Ethiopia, Nigeria and Pakistan-characterises these challenges. Our findings indicate that NPHIs' role necessitates collection and analysis of data from multiple sources that do not routinely share data with public health authorities. Since initiating requests for access to new data sources can be a lengthy process, it is essential that NPHIs are routinely monitoring a broad set of priority indicators that are selected to reflect the country-specific context. NPHIs must also have the authority to be able to request rapid sharing of data from public and private sector organisations during health emergencies and to access additional human and financial resources during disease outbreaks. Finally, timely, transparent and informative communication of synthesised data from NPHIs will facilitate sustained data sharing with NPHIs from external organisations. These actions identified by our analysis will support the availability of robust information systems that allow relevant data to be collected, shared and analysed by NPHIs sufficiently rapidly to inform a timely local response to infectious disease outbreaks in the future.

Free tissue transfer for burns reconstruction: A single-site experience

This study reviews free tissue transfer (FTT) surgery for both acute wound and reconstructive scar management of burn injuries at a UK burns unit over a 10-year period. Thirty eight patients underwent 46 FTTs, or free flaps, as part of their burn injury pathway. For the cohort of patients, there was one flap failure, which occurred for a secondary scar reconstruction. It is noted that FTT was successful for all seven acute or primary interventions. Anterolateral thigh flap was the most frequently performed (57%); followed by parascapular flaps (22%) of which 43% were pre-expanded. A method of pre-expansion for neck contractures and a novel technique of anchoring this flap to the pre-tracheal fascia are described here. This can provide the patient with good neck contouring by using the capsule to hitch the flap into a good position. It is clear that further work is required to study the prevention of hypertrophic scarring that can occur at the interface between flap and adjacent skin, where occurrence rate in this cohort was 17%. It is proposed that FTT now provides a viable solution both to the coverage of complex burn wounds and to the revision of scar contractures. Consensus over an FTT protocol for the primary management of open burn wounds is seen as the logical next step for this surgical intervention.

Methodological gaps and opportunities for studying multisectoral collaboration for health in low- and middle-income countries

The current body of research into multisectoral collaborations (MSCs) for health raises more questions than it answers, both in terms of how to implement MSCs and how to study them. This article reflects on current methodological gaps and opportunities for advancing MSC research, based on a targeted review of existing literature and qualitative input from researchers and practitioners at the 2018 Health Systems Research (HSR) Symposium in Liverpool. Through framework analysis of 205 MSC research papers referenced in a separately published MSC 'overview of reviews' paper, this article identifies six broad MSC question domains ('meta questions') and applies content analysis to estimate the relative frequency with which these meta questions and the research method(s) used to answer them are present in the literature. Results highlight a preponderance of research exploring MSC implementation using case study methods, which, in aggregate, does not seem to adequately meet policymakers' and practitioners' needs for generalizable or transferable insights. The content analysis is complemented by qualitative insights from HSR Symposium participants and the authors' own experience to identify six key methodological gaps in research on MSC for health. For each of these gaps, we propose areas in which we believe there are opportunities for methodological development and innovation to help advance this field of study, including: better understanding the role of power dynamics in shaping MSCs; development of a classification framework (or frameworks) of governance arrangements; exploring divergence of perspective and experience among MSC partners; identifying or generating theoretical frameworks for MSC that work across sectors and disciplines; developing intermediate indicators of collaboration; and increasing transferability of insights to other contexts. Collaboration with researchers outside of the health sector will enhance efforts in each of these areas, as will the establishment and strengthening of pluralistic MSC evidence networks also involving policymakers and practitioners.

Transient acantholytic dermatosis in a patient with prostate cancer

Transient acantholytic dermatosis (TAD) is a relatively common entity that has been also noted to occur in patients with cancer. Herein, we describe a case of transient acantholytic dermatosis occurring in a patient with a history of prostate cancer status post radiation, now being treated with combination therapy with pembrolizumab and carboplatin-pemetrexed for advanced lung adenocarcinoma. Our case emphasizes the importance of being cognizant of TAD and its associations, particularly in cancer patients.

Is enhancing the professionalism of healthcare providers critical to tackling antimicrobial resistance in low- and middle-income countries?

BACKGROUND

Healthcare providers' (HCPs) professionalism refers to their commitment and ability to respond to the health needs of the communities they serve and to act in the best interest of patients. Despite attention to increasing the number of HCPs in low- and middle-income countries (LMIC), the quality of professional education delivered to HCPs and their resulting professionalism has been neglected. The Global Action Plan on Antimicrobial Resistance (AMR) seeks to reduce inappropriate use of antibiotics by urging patients to access antibiotics only through qualified HCPs, on the premise that qualified HCPs will act as more responsible and competent gatekeepers of access to antibiotics than unqualified HCPs.

METHODS

We investigate whether weaknesses in HCP professionalism result in boundaries between qualified HCPs and unqualified providers being blurred, and how these weaknesses impact inappropriate provision of antibiotics by HCPs in two LMIC with increasing AMR-Pakistan and Cambodia. We conducted 85 in-depth interviews with HCPs, policymakers, and pharmaceutical industry representatives. Our thematic analysis was based on a conceptual framework of four components of professionalism and focused on identifying recurring findings in both countries.

RESULTS

Despite many cultural and sociodemographic differences between Cambodia and Pakistan, there was a consistent finding that the behaviour of many qualified HCPs did not reflect their professional education. Our analysis identified five areas in which strengthening HCP education could enhance professionalism and reduce the inappropriate use of antibiotics: updating curricula to better cover the need for appropriate use of antibiotics; imparting stronger communication skills to manage patient demand for medications; inculcating essential professional ethics; building skills required for effective collaboration between doctors, pharmacists, and lay HCPs; and ensuring access to (unbiased) continuing medical education.

CONCLUSIONS

In light of the weaknesses in HCP professionalism identified, we conclude that global guidelines urging patients to only seek care at qualified HCPs should consider whether HCP professional education is equipping them to act in the best interest of the patient and society. Our findings suggest that improvements to HCP professional education are needed urgently and that these should focus not only on the curriculum content and learning methods, but also on the social purpose of graduates.

P1731 Multiple floating thrombi in aortic arch leading to acute stroke: A case report and systematic review of literature

Introduction

Around 10-15% of acute cerebrovascular events occur in young adults with age less than 40 years. Trans-oesophageal echocardiogram (TOE) is routinely performed to rule out any cardio-embolic source in patients with ischemic stroke. TOE has shown to significantly change management strategy in up to 16.7% of stroke cases. We report a rare case of recurrent stroke in a young female who was found to have multiple mobile thrombi in aortic arch on TOE. We also report systematic review of literature of similar cases to highlight the management strategies.

Case Presentation

A 38-year-old female presented with one-week history of right upper and lower extremity paresthesia along with headache. Physical examination was unremarkable for any focal neurological deficits at time of initial evaluation. She had pertinent history of acute stroke two years ago associated with non-occlusive left common carotid artery thrombus for which she was previously on anticoagulation with rivaroxaban. The anticoagulation, however, was stopped five months ago after repeat imaging revealed complete resolution of thrombus. Electrocardiogram showed normal sinus rhythm without any other significant abnormality. CT head showed no acute bleeding or infarct. MRI brain showed scattered infarcts in right cerebral hemisphere and left cerebellar hemisphere. CT angiography of head and neck showed multiple small nodular and linear pedunculated thrombi in distal arch of aorta (see Figure 2). TOE was then performed which confirmed two pedunculated and mobile echogenic masses, largest measuring 0.9 x 0.6 cm, in the distal aortic arch (see Figure 1). TOE did not show intracardiac source of embolism. Laboratory testing for thrombophilia was negative for Factor V and Prothrombin gene mutation and heterozygous positive for Methylenetetrahydrofolate reductase (MTHFR)-677T gene. She was also found to have elevated homocysteine levels. She was restarted on anticoagulation with rivaroxaban.

Discussion and Conclusion

Young patients with stroke should undergo detailed investigation to rule out hypercoagulable pathology and cardiovascular embolic source. This should also include multimodality imaging including TOE in the selected patients. During TOE examination, a particular attention should be paid for evaluation of aortic source of thombo-embolism. Our patient was heterozygous for MTHFR-66T gene which is associated with decreassed activity of MTHFR by 35 % with elevated homocysteine levels. Treatment of floating aortic thrombus is still controversial. Anticoagulation is suggested as primary modality by multiple authors who reported complete resolution of thrombus. Other option includes surgical thrombectomy. Our patient was treated with anticoagulation alone due to hypercoagulable state and small size of thrombi.

'LMICs as reservoirs of AMR': a comparative analysis of policy discourse on antimicrobial resistance with reference to Pakistan

Antimicrobial resistance (AMR) has recently emerged as a salient global issue, and policy formulation to address AMR has become a contested space, with various actors sharing competing-and sometimes contradictory-explanations of the problem and the range of possible solutions. To facilitate national policy setting and implementation around AMR, more needs to be done to effectively engage policymakers in low- and middle-income countries (LMICs). However, there is a dearth of research on differences in issue framing by external agencies and LMIC's national policymakers on the problem of AMR; such analyses are imperative to identify areas of conflict and/or potential convergence. We compared representations of AMR across nine policy documents produced by multilateral agencies, donor countries and an LMIC at the forefront of the global response to AMR-Pakistan. We analysed the texts in relation to five narratives that have been commonly used to frame health issues as requiring action: economic impact, stunting of human development, consequences for health equity, health security threats and relationship with food production. We found that AMR was most frequently framed as a threat to human health security and economic progress, with several US, UK and international documents depicting LMICs as 'hotspots' for AMR. Human development and equity dimensions of the problem were less frequently discussed as reasons to address the growing burden of AMR. It is clear that no single coherent narrative on AMR has emerged, with notable differences in framing in Pakistani and external agency led documents, as well as across stakeholders primarily working on human vs animal health. While framing AMR as a threat to economic growth and human security has achieved high-level political attention and catalysed action from governments in high-income countries, our analysis suggests that conflicting narratives relevant to policymakers in Pakistan may affect policy-making and impede the development and implementation of integrated initiatives needed to tackle AMR.

Pre-grafting histological studies of skin grafts cryopreserved in α helix antarctic yeast oriented antifreeze peptide (Afp1m)

A number of living creatures in the Antarctic region have developed characteristic adaptation of cold weather by producing antifreeze proteins (AFP). Antifreeze peptide (Afp1m) fragment have been designed in the sequence of strings from native proteins. The objectives of this study were to assess the properties of Afp1m to cryopreserve skin graft at the temperature of -10 °C and -20 °C and to assess sub-zero injuries in Afp1m cryopreserved skin graft using light microscopic techniques. In the present study, a process was developed to cryopreserve Sprague-Dawley (SD) rat skin grafts with antifreeze peptide, Afp1m, α-helix peptide fragment derived from Glaciozyma antractica yeast. Its viability assessed by different microscopic techniques. This study also described the damages caused by subzero temperatures (-10 and -20 °C) on tissue cryopreserved in different concentrations of Afp1m (0.5, 1, 2, 5 and 10 mg/mL) for 72 h. Histological scores of epidermis, dermis and hypodermis of cryopreserved skin grafts showed highly significant difference (p < 0.01) among the different concentrations at -10 and -20 °C. In conclusion, the integrity of cryopreserved skin grafts with lower concentrations of Afp1m (0.5, 1 and 2 mg/mL) or at -20 °C was not maintained. The present study attested that Afp1m is a good cryoprotective agent for the cryopreservation of skin graft. Higher Afp1m concentrations (5 and 10 mg/mL) at -10 °C found to be suitable for the future in vivo study using (SD) rat skin grafts.

Invisible medicine sellers and their use of antibiotics: a qualitative study in Cambodia

BACKGROUND

Global attention to antimicrobial resistance has increased interest in tackling the widespread inappropriate dispensing of antibiotics by informal, for-profit healthcare providers (HCPs). We provide new evidence on an understudied group of informal HCPs: invisible medicine sellers (IMS) who operate without any marked facility. We investigated factors that influence community decisions on which HCPs to purchase medicines from, focusing on reasons for using IMS, and compared different HCPs' knowledge of antibiotic use.

METHODS

We conducted community focus group discussions (FGDs) in seven purposively selected villages representing high and low informal HCPs use in two peri-urban districts in Phnom Penh, Cambodia. Using information from the FGDs to identify HCPs that sell medicines, we interviewed 35 participants: 21 HCPs (including five IMS) and 14 key informants, including government HCPs and village leaders. We adopted an interpretative approach and conducted a thematic analysis.

RESULTS

Community members typically knew of several formal and informal HCPs selling medicines nearby, and IMS were common, as were doctors that sell medicines covertly. Two factors were most salient in influencing the choice of HCP for medicine purchasing. The first was trust in the effectiveness of medicines provided, judged by the speed of symptomatic relief. This pushed HCPs to provide several medicines, including antibiotics, at the first consultation. The second was the convenience offered by IMS and other informal HCPs: supplying medicines when other facilities are closed, accepting delayed payments, providing incomplete courses of medication and selling human antibiotics for animal use.

CONCLUSION

This first study focusing on IMS indicates that it is important, but challenging, for public health agencies to engage with them to reduce inappropriate use of antibiotics. Although public health facilities must fill some gaps that informal HCPs are currently addressing, such as access to medicines at night, reducing demand for unnecessary antibiotics is also critical.

What can motivate Lady Health Workers in Pakistan to engage more actively in tuberculosis case-finding?

Background

Many interventions to motivate community health workers to perform better rely on financial incentives, even though it is not clear that monetary gain is the main motivational driver. In Pakistan, Lady Health Workers (LHW) are responsible for delivering community level primary healthcare, focusing on rural and urban slum populations. There is interest in introducing large-scale interventions to motivate LHW to be more actively involved in improving tuberculosis case-finding, which is low in Pakistan.

Methods

Our study investigated how to most effectively motivate LHW to engage more actively in tuberculosis case-finding. The study was embedded within a pilot intervention that provided financial and other incentives to LHW who refer the highest number of tuberculosis cases in three districts in Sindh province. We conducted semi-structured interviews with 20 LHW and 12 health programme managers and analysed these using a framework categorising internal and external sources of motivation.

Results

Internal drivers of motivation, such as religious rewards and social recognition, were salient in our study setting. While monetary gain was identified as a motivator by all interviewees, programme managers expressed concerns about financial sustainability, and LHW indicated that financial incentives were less important than other sources of motivation. LHW emphasised that they typically used financial incentives provided to cover patient transport costs to health facilities, and therefore financial incentives were usually not perceived as rewards for their performance.

Conclusions

This study indicated that interventions in addition to, or instead of, financial incentives could be used to increase LHW engagement in tuberculosis case-finding. Our finding about the strong role of internal motivation (intrinsic, religious) in Pakistan suggests that developing context-specific strategies that tap into internal motivation could allow infectious disease control programmes to improve engagement of community health workers without being dependent on funding for financial incentives.

"For how long are we going to take the tablets?" Kenyan stakeholders' views on priority investments to sustainably tackle soil-transmitted helminths

Recent global commitments to shift responsibility for Neglected Tropical Disease (NTD) control to affected countries reflect a renewed emphasis on sustainability, away from aid-dependency. This calls for a better understanding of how domestic stakeholders perceive investments in different strategies for NTD control. Soil transmitted helminths (STH) are among the NTDs targeted for elimination as a public health problem by international agencies through mass drug administration, provided periodically to at-risk population groups, often using drugs donated by pharmaceutical companies. This study was conducted in Kenya at a time when responsibilities for long running STH programmes were transitioning from external to national and sub-national agencies. Following an initial assessment in which we identified key domestic stakeholders and reviewed relevant scientific and government documents, the perspectives of stakeholders working in health, education, community engagement and sanitation were investigated through semi-structured interviews with national level policymakers, county level policymakers, and frontline implementers in one high-STH burden county, Kwale. Our conceptual framework on sustainability traced a progression in thinking, from ensuring financial stability through the technical ability to adapt to changing circumstances, and ultimately to a situation where a programme is prioritised by domestic policymakers because empowered communities demand it. It was clear from our interviews that most Kenyan stakeholders sought to be at the final stage in this progression. Interviewees criticised long-term investment in mass drug administration, the approach favoured predominantly by external agencies, for failing to address underlying causes of STH. Instead they identified three synergistic priority areas for investment: changes in institutional structures and culture to reduce working in silos; building community demand and ownership; and increased policymaker engagement on underlying socioeconomic and environmental causes of STH. Although challenging to implement, the shift in responsibility from external agencies to domestic stakeholders may lead to emergence of new strategic directions.

Is knowledge retained by healthcare providers after training? A pragmatic evaluation of drug-resistant tuberculosis management in China

OBJECTIVES

Considering the urgent need of training to improve standardised management of drug-resistant infectious disease and the lack of evidence on the impact of training, this study evaluates whether training participants' knowledge on multidrug-resistant tuberculosis (MDR-TB) is improved immediately and a year after training.

SETTING AND PARTICIPANTS

The study involved 91 MDR-TB healthcare providers (HCPs), including clinical doctors, nurses and CDC staff, who attended a new MDR-TB HCP training programme in Liaoning and Jiangxi provinces, China.

MAIN OUTCOME MEASURES

A phone-based assessment of participants' long-term retention of knowledge about MDR-TB management was conducted in July 2017, approximately 1 year after training. The proportion of correct responses in the long-term knowledge assessment was compared with a pretraining test and an immediate post-training test using a χ2 test. Factors influencing participants' performance in the long-term knowledge assessment were analysed using linear regression.

RESULTS

Across both provinces, knowledge of definitions of drug-resistant TB, standardised MDR-TB case detection protocols and laboratory diagnosis was improved 1 year after the training by 14.5% (p=0.037), 32.4% (p<0.001) and 31% (p<0.001) relative to pretraining. However, compared with immediately after training, the knowledge of the three topics declined by 26.5% (p=0.003), 19.8% (p=0.018) and 52.7% (p<0.001) respectively in Jiangxi, while no significant decline was observed in Liaoning. Additionally, we found that obtaining a higher score in the long-term knowledge assessment was associated with longer years of clinical experience (coefficient=0.51; 95 CI% 0.02 to 0.99; p=0.041) and attending training in Liaoning (coefficient=0.50; 95% CI 0.14 to 0.85; p=0.007).

CONCLUSION

Our study, the first to assess knowledge retention of MDR-TB HCPs 1 year after training, showed an overall positive long-term impact of lecture-style group training on participants' knowledge. Knowledge decline 1 year after training was observed in one province, Jiangxi, and this may be partly addressed by targeted support to HCPs with fewer years of clinical experience.

An evaluation of the quality and content of web-based stoma information

AIM

Although the internet is commonly the first port of call for medical information, it provides unregulated data of variable quality. We aimed to evaluate commonly accessed web-based information on intestinal stomas using validated and novel scoring systems.

METHOD

The keywords 'stoma', 'colostomy', 'ileostomy' and 'bowel bag' were entered into the most commonly used internet search engines (Google, Bing and Yahoo). The first ten websites from each search were analysed using the validated Journal of the American Medical Association (JAMA) benchmark criteria and DISCERN scoring systems. A novel stoma-specific score was devised and applied.

RESULTS

Forty-three unique websites were identified. The majority (49%) were from nonprofit or governmental agencies and 9% were from commercial entities. The mean total DISCERN score for all websites was 42.4 ± 10.2 (maximum possible score = 75). The mean JAMA and stoma-specific scores were 2.1 ± 1.0 (maximum possible score = 4) and 12.9 ± 6.1 (maximum possible score = 27). The lowest JAMA scores were in the category of attribution, with 70% of websites lacking references for the information provided. A total of 88% displayed disclosure/paid advertiser information. Surgery was described in 67%. An image or diagram was provided in 58% and in 72% a stoma therapist/nurse was mentioned. Information on when to seek medical help was provided in 51%.

CONCLUSION

Web-based information on stomas is of variable content and quality. Authorship and information sources are often unclear. Only half provided information on when to seek medical help for complications including high output and dehydration. These findings should be highlighted to patients who utilize the internet to obtain information on stomas.

Trifocal versus bifocal bone transport in treatment of long segmental tibial bone defects

AIMS

Many authors have reported a shorter treatment time when using trifocal bone transport (TFT) rather than bifocal bone transport (BFT) in the management of long segmental tibial bone defects. However, the difference in the incidence of additional procedures, the true complications, and the final results have not been investigated.

PATIENTS AND METHODS

A total of 86 consecutive patients with a long tibial bone defect (≥ 8 cm), who were treated between January 2008 and January 2015, were retrospectively reviewed. A total of 45 were treated by BFT and 41 by TFT. The median age of the 45 patients in the BFT group was 43 years (interquartile range (IQR) 23 to 54).

RESULTS

The size of the bone defect was significantly longer (p = 0.005), the number of previous operations was significantly higher (p < 0.001), the operating time was significantly longer (p < 0.001), and the bone transport distance was significantly increased (p = 0.017) in the TFT group. However, the external fixation time (p < 0.001), the healing index (p < 0.001), the number of additional procedures (p = 0.013), and the number of true complications (p < 0.001) were significantly reduced in this group. Both groups achieved highly satisfactory bone and functional results.

CONCLUSION

TFT can significantly reduce the treatment time, the number of additional surgical procedures, and true complications compared with BFT in the treatment of long segmental tibial bone defects.

Detection of prostate specific antigen (PSA) in human saliva using an ultra-sensitive nanocomposite of graphene nanoplatelets with diblock-co-polymers and Au electrodes

Prostate-specific antigen (PSA) is a commonly used biomarker for the detection of prostate cancer (PCa) and there are numerous data available for its invasive detection in the serum and whole blood. In this work, an electrochemical sensing method was devised to detect traces of PSA in human saliva using a hybrid nanocomposite of graphene nanoplatelets with diblock co-polymers and Au electrodes (GRP-PS₆₇-b-PAA₂₇-Au). The pure graphitic composition on filter paper provides significantly high electrical and thermal conductivity while PS₆₇-b-PAA₂₇ makes an amphiphilic bridge between GRP units. The sensor utilizes the binding of an anti-PSA antibody with an antigen-PSA to act as a resistor in a circuit providing an impedance change that in turn allows for the detection and quantification of PSA in saliva samples. A miniaturized electrical impedance analyzer was interfaced with a sensor chip and the data were recorded in real-time using a Bluetooth-enabled module. This fully integrated and optimized sensing device exhibited a wide PSA range of detection from 0.1 pg mL^-1 to 100 ng mL^-1 (R² = 0.963) with a lower limit of detection of 40 fg mL^-1. The performance of the biosensor chip was validated with an enzyme-linked immunosorbent assay technique with a regression coefficient as high as 0.940. The advantages of the newly developed saliva-PSA electrical biosensor over previously reported serum-PSA electrochemical biosensors include a faster response time (3-5 min) to achieve a stable electrical signal for PSA detection, high selectivity, improved sensitivity, no additional requirement of a redox electrolyte for electron exchange and excellent shelf life. The presented sensor is aimed for clinical commercialization to detect PSA in human saliva.

Variations in the Position of Vermiform Appendix in Bangladeshi People

This cross sectional descriptive study was performed on 70 postmortem vermiform appendices (male 34 and female 36) to find out the various positions of vermiform appendix of Bangladeshi people. The specimens were collected from autopsy laboratory of the Department of Forensic Medicine, Mymensingh Medical College, Mymensingh, Bangladesh by purposive sampling technique from October 2016 to March 2017. The collected samples were divided into four age groups. They were Group A (upto 20 years), Group B (21 to 40 years), Group C (41 to 60 years) and Group D (above 60 years). Dissection was performed according to standard autopsy technique. During postmortem examination abdominal cavity was routinely exposed by classical midline incision from xiphoid process to the symphysis pubis and a semicircular incision around the umbilicus and the flaps were reflected to give a good view of the abdominal cavity along with its contents and then the taeniae coli of the caecum were identified. The three taeniae coli of the caecum converge at the base of the appendix and become its longitudinal muscle coat. The anterior caecal taeniae coli acts as the best guide for identification of the vermiform appendix. The relation of the base of the appendix to the caecum is constant but the position of the vermiform appendix, which is variable, was studied in relation to caecum and the terminal part of the ileum. Accordingly the position of the vermiform appendix was noted either retrocaecal, pelvic, preileal or postileal, subcaecal. All data were recorded in the predesigned data sheet, analyzed by SPSS program (version 21, 2012) and compared with the findings of other national and international studies and standard text books. Among 70 specimens, 44(62.9%) vermiform appendices were retrocaecal in position. The next common position was pelvic which was in 22(31.4%) specimen followed by postileal in 3(4.3%) specimen and subcaecal was observed only in 1(1.4%) specimen. In this study in all age groups incidence of retrocaecal vermiform appendix was highest and it was about 67.6%, 50%, 69.2% and 72.7% in Group A, B, C, D respectively. Pelvic position was 7.1%, 46.9%, 23.1% and 27.3% in Group A, B, C, D respectively. Subcaecal vermiform appendix was absent in Group A, B and Group D. On the other hand postileal vermiform appendix was absent in Group C and Group D. The findings of this study may help the physician and the surgeons for proper diagnosis, management and treatment of disease of vermiform appendix.

Something Borrowed, Something New: A Governance and Social Construction Framework to Investigate Power Relations and Responses of Diverse Stakeholders to Policies Addressing Antimicrobial Resistance

While antimicrobial resistance (AMR) has rapidly ascended the political agenda in numerous high-income countries, developing effective and sustainable policy responses in low- and middle-income countries (LMIC) is far from straightforward, as AMR could be described as a classic ‘wicked problem’. Effective policy responses to combat AMR in LMIC will require a deeper knowledge of the policy process and its actors at all levels—global, regional and national—and their motivations for supporting or opposing policies to combat AMR. The influence of personal interests and connections between for-profit organisations—such as pharmaceutical companies and food producers—and policy actors in these settings is complex and very rarely addressed. In this paper, the authors describe the role of policy analysis focusing on social constructions, governance and power relations in soliciting a better understanding of support and opposition by key stakeholders for alternative AMR mitigation policies. Owing to the lack of conceptual frameworks on the policy process addressing AMR, we propose an approach to researching policy processes relating to AMR currently tested through our empirical programme of research in Cambodia, Pakistan, Indonesia and Tanzania. This new conceptualisation is based on theories of governance and a social construction framework and describes how the framework is being operationalised in several settings.
