Percutaneous Route of Life: Chylothorax or Total Parenteral Nutrition-Related Bilateral Pleural Effusion in a Neonate?

OBJECTIVE: Peripherally Inserted Central Catheter (PICC) lines are an essential tool in the management of premature neonates. Pleural effusion (PLE) secondary to the leakage of alimentation into the pleural cavity is an encountered complication of central-line total parenteral nutrition (TPN) administration. Methods: We review a case of a premature neonate who suffered large, bilateral PLE after insertion of an upper extremity PICC line for TPN. Results: Pleural fluid biochemical analysis confirmed PICC line infiltration, predominantly with monocytes, low protein, high triglycerides and high glucose. These results favored TPN leakage over chylothorax. Conclusions: To our knowledge, this is the first case of bilateral PLE due to PICC complication in a neonate, which highlights the importance of chylothorax differential diagnosis, the role of autopsy, and the need for clinical precautions when providing premature neonates with high osmolarity TPN.

CT-Based 3D Printing of the Glenoid Prior to Shoulder Arthroplasty: Bony Morphology and Model Evaluation.

To demonstrate the 3D printed appearance of glenoid morphologies relevant to shoulder replacement surgery and to evaluate the benefits of printed models of the glenoid with regard to surgical planning. A retrospective review of patients referred for shoulder CT was performed, leading to a cohort of nine patients without arthroplasty hardware and exhibiting glenoid changes relevant to shoulder arthroplasty planning. Thin slice CT images were used to create both humerus-subtracted volume renderings of the glenoid, as well as 3D surface models of the glenoid, and 11 printed models were created. Volume renderings, surface models, and printed models were reviewed by a musculoskeletal radiologist for accuracy. Four fellowship-trained orthopaedic surgeons specializing in shoulder surgery reviewed each case individually as follows: First, the source CT images were reviewed, and a score for the clarity of the bony morphologies relevant to shoulder arthroplasty surgery was given. The volume rendering was reviewed, and the clarity was again scored. Finally, the printed model was reviewed, and the clarity again scored. Each printed model was also scored for morphologic complexity, expected usefulness of the printed model, and physical properties of the model. Mann-Whitney-Wilcoxon signed rank tests of the clarity scores were calculated, and the Spearman's ρ correlation coefficient between complexity and usefulness scores was computed. Printed models demonstrated a range of glenoid bony changes including osteophytes, glenoid bone loss, retroversion, and biconcavity. Surgeons rated the glenoid morphology as more clear after review of humerus-subtracted volume rendering, compared with review of the source CT images (p = 0.00903). Clarity was also better with 3D printed models compared to CT (p = 0.00903) and better with 3D printed models compared to humerus-subtracted volume rendering (p = 0. 00879). The expected usefulness of printed models demonstrated a positive correlation with morphologic complexity, with Spearman's ρ 0.73 (p = 0.0108). 3D printing of the glenoid based on pre-operative CT provides a physical representation of patient anatomy. Printed models enabled shoulder surgeons to appreciate glenoid bony morphology more clearly compared to review of CT images or humerus-subtracted volume renderings. These models were more useful as glenoid complexity increased.

Cardiac Applications of PET-MR.

PURPOSE OF REVIEW: The purpose of this study was to provide an overview of the clinical applications of PET-MR in the setting of cardiac imaging with emphasis on specific scenarios where both techniques together provided added information. RECENT FINDINGS: Synergy of cardiac PET and MR fusion may hold similar promise eliminating ionizing radiation and improving tissue contrast. Future development of new hybrid scanners, use of new imaging tracers, and clinical applications are significant factors which will influence its use. Both positron emission tomography (PET) and cardiac magnetic resonance imaging (CMR) provide important anatomic and physiologic information with regard to the heart. Being able to combine the data from these two examinations in a hybrid technique allows for a more complete evaluation of cardiac pathology. While hybrid PET-CT has already established the utility of a combined imaging approach, the use of CMR in lieu of CT allows for elimination of ionizing radiation and for improved tissue contrast.

Reaccreditation of non-medical prescribers: maintaining competence.

There is no systematic and robust method to assess the competence of non-medical prescribers (NMPs) locally or nationally. NMPs have a responsibility to remain up to date with the knowledge and skills to enable them to prescribe competently and safely within their field of expertise. In 2012, the National Prescribing Centre developed a single competency framework for prescribers defining a set of nine dimensions within three domains that can be used to underpin personal responsibility for prescribing. The authors identified validated assessment tools using a literature search, and selected those suitable for mapping against the nine dimensions. It was hoped that trust NMPs could provide evidence of competence covering all three of the framework domains using the chosen tools. Five NMPs used the tools to create a portfolio and audited them for suitability in establishing a robust and credible evidence-led system to evaluate and accredit ongoing competence. Feedback on their ease of use and applicability was sought. Trust NMPs were then invited to a workshop where the evidence was presented and they were asked to comment on, and contribute to, finalising the tools before they were embedded within trust policy.

Why local antibiotic resistance data matters - Informing empiric prescribing through local data collation, app design and engagement in Zambia.

BACKGROUND: Control of antimicrobial resistance (AMR) relies on local knowledge and local intervention implementation. Effective antibiotic stewardship requires locally-suitable prescribing guidelines. We aimed to use a novel digital tool (the ZARIApp) and a participatory approach to help develop locally-relevant empiric antibiotic prescribing guidelines for two hospitals in Lusaka, Zambia. METHODS: We produced an AMR report using samples collected locally and routinely from adults within the prior two years (April 2020 - April 2022). We developed the ZARIApp, which provides prescribing recommendations based on local resistance data and antibiotic prescribing practices. We used qualitative evaluation of focus group discussions among healthcare professionals to assess the feasibility and acceptability of using the ZARIApp and identify the barriers to and enablers of this stewardship approach. RESULTS: Resistance prevalence was high for many key pathogens: for example, 73% of 41 Escherichia coli isolates were resistant to ceftriaxone. We identified that high resistance rates were likely due to low levels of requesting and processing of microbiology samples from patients leading to insufficient and unrepresentative microbiology data. This emerged as the major barrier to generating locally-relevant guidelines. Through active stakeholder engagement, we modified the ZARIApp to better support users to generate empirical antibiotic guidelines within this context of unrepresentative microbiology data. Qualitative evaluation of focus group discussions suggested that the resulting ZARIApp was useful and easy to use. New antibiotic guidelines for key syndromes are now in place in the two study hospitals, but these have substantial residual uncertainty. CONCLUSIONS: Tools such as the free online ZARIApp can empower local settings to better understand and optimise how sampling and prescribing can help to improve patient care and reduce future AMR. However, the usability of the ZARIApp is severely limited by unrepresentative microbiology data; improved routine microbiology surveillance is vitally needed.

Inflammatory bowel disease patient-reported quality assessment should drive service improvement: a national survey of UK IBD units and patients.

BACKGROUND: Healthcare service provision in inflammatory bowel disease (IBD) is often designed to meet targets set by healthcare providers rather than those of patients. It is unclear whether this meets the needs of patients, as assessed by patients themselves. AIMS: To assess patients' experience of IBD and the healthcare they received, aiming to identify factors in IBD healthcare provision associated with perceived high-quality care. METHODS: Using the 2019 IBD standards as a framework, a national benchmarking tool for quality assessment in IBD was developed by IBD UK, comprising a patient survey and service self-assessment. RESULTS: 134 IBD services and 9757 patients responded. Perceived quality of care was lowest in young adults and increased with age, was higher in males and those >2 years since diagnosis. No hospital services met all the national IBD standards for recommended workforce numbers. Key metrics associated with patient-reported high- quality care were: identification as a tertiary centre, patient information availability, shared decision- making, rapid response to contact for advice, access to urgent review, joint medical/surgical clinics, and access to research (all p < 0.001). Higher numbers of IBD nurse specialists in a service was strongly associated with patients receiving regular reviews and having confidence in self-management and reporting high- quality care. CONCLUSIONS: This extensive patient and healthcare provider survey emphasises the importance of aspects of care less often measured by clinicians, such as communication, shared decision- making and provision of information. It demonstrates that IBD nurse specialists are crucial to meeting the needs of people living with IBD.

Inflammatory bowel disease psychological support pilot reduces inflammatory bowel disease symptoms and improves psychological wellbeing.

This prospective service evaluation aimed to determine if integrated psychological support for patients with inflammatory bowel disease (IBD) enhanced outcomes. 75 patients were assessed and treated by a specialist liaison psychiatric service between 2015 and 2017; 43 received psychiatric intervention alone, 32 were referred for psychological intervention by clinical health psychologist; 26 completed this. Pre-post data (n=15 available) included global impression, quality of life, and psychiatric and IBD symptom scores. Referrer/patient satisfaction and cost-effectiveness were retrospectively calculated. Psychological intervention led to reductions in IBD symptoms (ΔSIBD; p=0.003), alongside improvements in depression scores (ΔPHQ-9, p=0.006) and global impression (ΔCGI; p=0.046). Patient/referrer satisfaction was very high. Indicative data comparing service utilisation 1 year before and after engagement found reductions in outpatient appointments and in imaging. This small study suggests consideration of increased access to integrated psychological support services to improve outcomes and gather further evidence of efficacy.

Antibiotic Prescribing Patterns in Ghana, Uganda, Zambia and Tanzania Hospitals: Results from the Global Point Prevalence Survey (G-PPS) on Antimicrobial Use and Stewardship Interventions Implemented.

Antimicrobial resistance (AMR) remains an important global public health issue with antimicrobial misuse and overuse being one of the main drivers. The Global Point Prevalence Survey (G-PPS) of Antimicrobial Consumption and Resistance assesses the prevalence and the quality of antimicrobial prescriptions across hospitals globally. G-PPS was carried out at 17 hospitals across Ghana, Uganda, Zambia and Tanzania. The overall prevalence of antimicrobial use was 50% (30-57%), with most antibiotics prescribed belonging to the WHO 'Access' and 'Watch' categories. No 'Reserve' category of antibiotics was prescribed across the study sites while antimicrobials belonging to the 'Not Recommended' group were prescribed infrequently. Antimicrobials were most often prescribed for prophylaxis for obstetric or gynaecological surgery, making up between 12 and 18% of total prescriptions across all countries. The most prescribed therapeutic subgroup of antimicrobials was 'Antibacterials for systemic use'. As a result of the programme, PPS data are now readily available for the first time in the hospitals, strengthening the global commitment to improved antimicrobial surveillance. Antimicrobial stewardship interventions developed included the formation of AMS committees, the provision of training and the preparation of new AMS guidelines. Other common interventions included the presentation of findings to clinicians for increased awareness, and the promotion of a multi-disciplinary approach to successful AMS programmes. Repeat PPS would be necessary to continually monitor the impact of interventions implemented. Broader participation is also encouraged to strengthen the evidence base.

Personalised Adherence Support for Maintenance Treatment of Inflammatory Bowel Disease: A Tailored Digital Intervention to Change Adherence-related Beliefs and Barriers.

BACKGROUND AND AIMS: Interventions to improve adherence to medication may be more effective if tailored to the individual, addressing adherence-related beliefs about treatment and overcoming practical barriers to daily use. We evaluated whether an algorithm, tailoring support to address perceptual and practical barriers to adherence, reduced barriers and was acceptable to patients with inflammatory bowel disease [IBD]. METHODS: Participants with IBD, prescribed azathioprine and/or mesalazine, were recruited via patient groups, social media, and hospital clinics and allocated to Intervention or Control Groups. The online intervention comprised messages tailored to address beliefs about IBD and maintenance treatment and to provide advice on overcoming practical difficulties with taking regular medication. The content was personalised to address specific perceptual and practical barriers identified by a pre-screening tool. Validated questionnaires assessed barriers to adherence and related secondary outcomes at baseline and at 1 and 3 months of follow-up. RESULTS: A total of 329 participants were allocated to the Intervention [n = 153] and Control [n = 176] Groups; just under half [46.2%] completed follow-up. At 1 and 3 months, the Intervention Group had significantly fewer concerns about IBD medication [p ≤0.01]; and at three months, fewer doubts about treatment necessity, fewer reported practical barriers, and higher reported adherence [p <0.05]. Relative to controls at follow-up, the Intervention Group were more satisfied with information about IBD medicines, and viewed pharmaceuticals in general more positively. Questionnaires, interviews, and intervention usage indicated that the intervention was acceptable. CONCLUSIONS: Personalised adherence support using a digital algorithm can help patients overcome perceptual barriers [doubts about treatment necessity and medication concerns] and practical barriers to adherence.

Correction to: Treatment of Rare and Aggressive Pancreatic Carcinosarcoma.

[This corrects the article on p. e00379 in vol. 7, PMID: 32607379.].

Treatment of Rare and Aggressive Pancreatic Carcinosarcoma.

A 42-year-old African American woman presented with 4 days of worsening midepigastric pain that radiated to her back. Computed tomography confirmed a diagnosis of acute pancreatitis and revealed a mass within the distal body and tail of the pancreas. After an endoscopic ultrasound with fine-needle aspiration yielding atypical cells suspicious for adenocarcinoma, the patient underwent an en bloc resection of the intra-abdominal mass with subtotal pancreatectomy, splenectomy, left colectomy, and left partial adrenalectomy. Histopathologic examination findings, in addition to immunohistochemical staining, revealed a diagnosis of pancreatic carcinosarcoma. Postoperatively, the patient has undergone 20 cycles of chemotherapy and has been transitioned to comfort measures at 16 months postoperatively because of progressive disease.

Understanding and Minimising Injection-Site Pain Following Subcutaneous Administration of Biologics: A Narrative Review.

Injection-site pain (ISP) is a subjective side effect that is commonly reported with the subcutaneous administration of biological agents, yet it may only be a concern to some. Multiple factors related to the product formulation, such as pH, volume and excipients, and/or to the injection process have the potential to contribute to ISP, while patient-related factors, such as low body weight, gender and age, can make an individual more susceptible to experiencing ISP. While total elimination of ISP remains unlikely with any subcutaneously administered agent, it can be minimised by helping the patient to develop a confident and competent injection technique via robust and effective training. Careful management of patient expectations along with open discussion regarding the potential risk of ISP may serve to minimise treatment-related anxieties and, importantly, allow the patient to remain in control of his/her treatment. Other interventions to help minimise ISP include psychological interventions, allowing biologics to reach room temperature prior to injection, using the most suitable injection device for the individual patient and selecting an alternative drug formulation, when available. Productive patient-physician communication remains important in order to support and optimise treatment experience and adherence, while also providing the opportunity for patients to discuss any ISP-related issues.

A Case Report of Alloimmune Hepatitis after Direct-acting Antiviral Treatment in a Liver Transplant Patient.

Direct-acting antiviral (DAA) therapy is often well-tolerated, and adverse events from DAA therapy are uncommon. We report a case of a woman who underwent orthotopic liver transplant for chronic hepatitis C infection and later developed alloimmune hepatitis shortly after starting DAA therapy for recurrent hepatitis C infection. The patient developed acute alloimmune hepatitis approximately 2 weeks after starting treatment with sofosbuvir, velpatasvir, and voxilaprevir. This case report proposes a dysregulation of immune surveillance due to the DAA stimulation of host immunity and rapid elimination of hepatitis C viral load as a precipitating factor for the alloimmune process, leading to alloimmune hepatitis in a post-transplant patient who starts on DAA.

Consensus standards of healthcare for adults and children with inflammatory bowel disease in the UK.

OBJECTIVE: Symptoms and clinical course during inflammatory bowel disease (IBD) vary among individuals. Personalised care is therefore essential to effective management, delivered by a strong patient-centred multidisciplinary team, working within a well-designed service. This study aimed to fully rewrite the UK Standards for the healthcare of adults and children with IBD, and to develop an IBD Service Benchmarking Tool to support current and future personalised care models. DESIGN: Led by IBD UK, a national multidisciplinary alliance of patients and nominated representatives from all major stakeholders in IBD care, Standards requirements were defined by survey data collated from 689 patients and 151 healthcare professionals. Standards were drafted and refined over three rounds of modified electronic-Delphi. RESULTS: Consensus was achieved for 59 Standards covering seven clinical domains; (1) design and delivery of the multidisciplinary IBD service; (2) prediagnostic referral pathways, protocols and timeframes; (3) holistic care of the newly diagnosed patient; (4) flare management to support patient empowerment, self-management and access to specialists where required; (5) surgery including appropriate expertise, preoperative information, psychological support and postoperative care; (6) inpatient medical care delivery (7) and ongoing long-term care in the outpatient department and primary care setting including shared care. Using these patient-centred Standards and informed by the IBD Quality Improvement Project (IBDQIP), this paper presents a national benchmarking framework. CONCLUSIONS: The Standards and Benchmarking Tool provide a framework for healthcare providers and patients to rate the quality of their service. This will recognise excellent care, and promote quality improvement, audit and service development in IBD.

Pitfalls of Frozen Section in Gynecological Pathology: A Case of Ovarian Serous Surface Papillary Adenofibroma Imitating Malignancy.

Serous cystadenofibromas are uncommon benign ovarian lesions, consisting of both fibrous and epithelial components, that are usually cystic but may contain solid or papillary architecture that can be confused with a malignancy on imaging. Papillary architecture seen on frozen section may also falsely steer the pathologist in the direction of a diagnosis of a borderline serous tumor. Overcalling the lesion may lead to more aggressive surgery than necessary, so extensive tissue sampling and consideration of this entity is important in possibly avoiding this mistake.

Antimicrobial stewardship knowledge and perception among physicians and pharmacists at leading tertiary teaching hospitals in Zambia: implications for future policy and practice.

Antimicrobial stewardship (AMS) is a key strategy promoting rational antimicrobial use. In Zambia, information on health professionals' knowledge, attitude, and practice of AMS is limited. This study was undertaken to address this at Zambia's leading specialized teaching hospitals. Descriptive, cross-sectional study involved 137 physicians and 61 pharmacists. AMS knowledge was relatively low among physicians (51%) and pharmacists (39%). Few physicians (9%) and pharmacists (20%) demonstrated sufficient knowledge of the basic principles of AMS. Physicians' and pharmacists' knowledge levels were significantly associated with years of practice, job position or practice rank, and previous AMS training. The majority (95%) perceived AMR as a current problem in their practise. Most physicians (92%) and pharmacists (86%) had not undertaken AMS training before. All indicated the need for context-specific educational interventions to promote AMS in Zambia. Despite positive perceptions, basic knowledge of AMS was relatively low. Context-specific educational interventions and capacity building are needed to address AMS gaps.

Measurement of Retinal Microvascular Blood Velocity Using Erythrocyte Mediated Velocimetry.

Changes in retinal blood flow may be involved in the pathogenesis of glaucoma and other ocular diseases. Erythrocyte mediated velocimetry (EMV) is a novel technique where indocyanine green (ICG) dye is sequestered in erythrocyte ghosts and autologously re-injected to allow direct visualization of erythrocytes for in vivo measurement of speed. The purpose of this study is to determine the mean erythrocyte speed in the retinal microvasculature, as well as the intravisit and intervisit variability of EMV. Data from 23 EMV sessions from control, glaucoma suspect, and glaucoma patients were included in this study. In arteries with an average diameter of 43.11 µm ± 6.62 µm, the mean speed was 7.17 mm/s ± 2.35 mm/s. In veins with an average diameter of 45.87 µm ± 12.04 µm, the mean speed was 6.05 mm/s ± 1.96 mm/s. Intravisit variability, as measured by the mean coefficient of variation, was 3.57% (range 0.44-9.68%). Intervisit variability was 4.85% (range 0.15-8.43%). EMV may represent reliable method for determination of retinal blood speed, potentially allowing insights into the effects of pharmacologic agents or pathogenesis of ocular diseases.
