High-Dose Buprenorphine Initiation in the Management of Opioid Use Disorder in Pregnancy

Buprenorphine is commonly used as a treatment for opioid use disorder (OUD). Transition to buprenorphine traditionally has been done using a low-dose initiation regimen due to concerns surrounding precipitated withdrawal. There are increasing data supporting use of a high-dose initiation regimen in the nonpregnant population. This retrospective case series describes six individuals with OUD who underwent high-dose buprenorphine initiation in pregnancy. There were no instances of sedation, respiratory depression, supplemental oxygen use, or death. All individuals were successfully transitioned to buprenorphine. These findings provide support for high-dose buprenorphine initiation in pregnancy, but future large studies are needed.

A comprehensive overview by region of condoms, natural family planning, and spermicide as a contraceptive method among men aged 13-54 years attending contraceptive services in England

OBJECTIVES

This study aimed to (1) provide a comprehensive overview of contraceptive methods self-reported by men in England, over 5 years, focusing on condoms in comparison to any male method; and (2) explore condom as a contraceptive method by region and ethnicity.

STUDY DESIGN

Data were from the Sexual and Reproductive Health Services (Contraception) England census data set from 2014/15 to 2018/19. Once missing data were removed, this left a total of 365,292 men. Two binomial logistic regression models were performed. Model 1 examined ethnicity, region, and time on condom as a method of contraception; and Model 2 examined ethnicity, region, and time by any male contraceptive. Descriptive statistics were run for natural family planning and spermicide.

RESULTS

Model 1 revealed a significant model, χ² (15) = 30,976, P < 0.001, and predicted that condoms as a method decreased in London with a greater decrease in Midlands. London saw the lowest rate of decline among the non-White ethnic group, whereas North and South regions increased probability over time. The North started at a higher probability and the South at the lowest. Model 2 also revealed a significant model, χ² (15) = 32,472, P < 0.001, with a similar pattern to Model 1. Contingency tables showed natural family planning and spermicide were the least reported methods and decreased over time.

CONCLUSIONS

As any male contraceptive method appears to be decreasing in both models, reproductive health promotion is required. This study has implications for commissioning funds and for identifying regional areas of further investigation.

Pan-cancer analysis of fear of cancer recurrence among cancer survivors

Background

Fear of cancer recurrence (FCR) is a phenomenon estimated to affect a large portion of cancer survivors. This study sought to determine whether patients from a National Cancer Institute-designated institution had their clinical needs met relating to FCR.

Patients and methods

Patients referred to the survivorship clinic completed The Clinical Needs Assessment Tool for Cancer Survivors (CNAT-CS). Correlations between responses were calculated and univariable and multivariable logistic regression was used to identify predictors of met or unmet needs related to FCR.

Results

Of 647 patients, 241 (37.2%) reported they did not have clinical needs related to FCR and 386 (59.7%) reported they had clinical needs related to FCR but that the needs had been met. Only 20 (3.09%) reported that clinical needs relating to FCR were unmet. According to univariate logistic regression, sex had no impact on FCR (P = 0.8427), nor did years since diagnosis (P = 0.1014). Results of multivariable regression indicate that the odds ratio of reported FCR as an unmet need (versus not a need) is 0.939; the odds decreased by 6% (P = 0.0023) for every year increase in age. For each unit increase in distress score, the odds of reporting FCR as an unmet need increased by 32% (P = 0.0007).

Conclusions

This study is unique in not only examining the presence of FCR but also whether patients reported that their needs were met for FCR. The study found that most patients had clinical needs for FCR, but the needs were met at the time of the survey. Patients who report higher distress scores are more likely to report FCR as an unmet need. Therefore, cancer survivors reporting high distress scores in clinic visits should be evaluated for FCR.

•

FCR is common among cancer survivors; it can be seen as a met or unmet need by each patient.

•

Identifying factors that influence fear of cancer recurrence as a need met or not include age and distress score.

•

Recognizing FCR as an unmet need is paramount to develop clinics and mitigation strategies to ameliorate this need.

POS1574-PARE PATIENTS REPORT HIGH LEVELS OF CONCERNS ABOUT MEDICATION FOR PSORIATIC AND RHEUMATOID ARTHRITIS: UNMET NEEDS REVEALED BY A UK PILOT WEB SURVEY

Background

Patients with rheumatoid arthritis (RA) and psoriatic arthritis (PsA) are often nonadherent to prescribed symptom-modifying drugs. [1] Concerns about the potential negative effects of medication have been implicated in medication nonadherence. Few evidence-based interventions to address concerns about medication and support medication-taking are available in the UK context.

Objectives

To inform the development of intervention to support people with RA and PsA to manage medication we conducted a survey of unmet needs relating to perceptions of arthritis and arthritis medication, medication-taking behaviour and experience of side effects.

Methods

We recruited people with arthritis via local and national patient groups for participation in an online survey. The survey included clinical and demographic questions, validated measures of treatment (Beliefs about Medication Questionnaire; BMQ) and illness perceptions (brief Illness Perception Questionnaire; bIPQ), medication adherence (Compliance Questionnaire Rheumatology; CQR), and patient-reported side effects. Participants were asked about consequences of taking and not taking their arthritis medication as free text to contextualize scores.

Results

Questionnaire responses from 98 participants (42 with PsA, 56 with RA, 89.8% female) indicated participants typically viewed arthritis negatively with ratings on the bIPQ indicating high emotional impacts, symptoms and affects on everyday life, and doubts about their ability to control their arthritis. Analysis of the BMQ indicated ambivalence about RA/PsA medications; while few people expressed doubts about their personal need for medication, concerns about RA/PsA medications were common, see Figure 1). Most, 85.7% (n=84), reported a side effect in the last month, with a mean of 10 ‘moderately severe’ or ‘very severe’ side effects (m=10.02, sd = 5.98). Just over a quarter (26.0%, n=25) were classed as low adherers using the CQR with 54.6% reporting they had missed some of their arthritis medication over the last year. Free text responses indicated that some participants had additional concerns about medication (e.g. worries about impact on life expectancy) not addressed in the questionnaire measures.

Conclusion

In this pilot survey, many participants reported concerns about medication, doubts about whether medication controls arthritis symptoms, severe side effects and medication nonadherence. Although our small sample is unlikely to be generalizable to all arthritis patients, these findings suggest potential targets for intervention and indicate that some patients have needs for support with medication that are not currently being addressed.

132 GERIATRIC REHABILITATION IN THE COVID-19 ERA: SERVICE INNOVATION AND PATIENT OUTCOMES

Background

Results

Conclusion

Bronchiectasis is associated with delayed diagnosis and adverse outcomes in the New Zealand Common Variable Immunodeficiency Disorders cohort study

Common variable immunodeficiency disorders (CVID) are multi-system disorders where target organ damage is mediated by infective, autoimmune and inflammatory processes. Bronchiectasis is probably the most common disabling complication of CVID. The risk factors for bronchiectasis in CVID patients are incompletely understood. The New Zealand CVID study (NZCS) is a nationwide longitudinal observational study of adults, which commenced in 2006. In this analysis, the prevalence and risk factors for bronchiectasis were examined in the NZCS. After informed consent, clinical and demographic data were obtained with an interviewer-assisted questionnaire. Linked electronic clinical records and laboratory results were also reviewed. Statistical methods were applied to determine if variables such as early-onset disease, delay in diagnosis and increased numbers of infections were associated with greater risk of bronchiectasis. One hundred and seven adult patients with a diagnosis of CVID are currently enrolled in the NZCS, comprising approximately 70% of patients known to have CVID in New Zealand. Fifty patients (46·7%) had radiologically proven bronchiectasis. This study has shown that patients with compared to those without bronchiectasis have an increased mortality at a younger age. CVID patients with bronchiectasis had a greater number of severe infections consequent to early-onset disease and delayed diagnosis. Indigenous Māori have a high prevalence of CVID and a much greater burden of bronchiectasis compared to New Zealand Europeans. Diagnostic latency has not improved during the study period. Exposure to large numbers of infections because of early-onset disease and delayed diagnosis was associated with an increased risk of bronchiectasis. Earlier diagnosis and treatment of CVID may reduce the risk of bronchiectasis and premature death in some patients.

Pharmacy professionals’ views regarding the future of NHS patient medicines helpline services: A multimethod qualitative study

Introduction

Patient medicines helpline services (PMHS) have been established at some National Health Service (NHS) hospitals in England, to provide medicines-related support to recently discharged hospital patients and carers. However, findings suggest that, due to a lack of resources, considerable variation exists in the operation of PMHS, and that their access, availability, and promotion do not meet national standards regarding helpline provision (1, 2). To develop recommendations for service improvement, this qualitative study sought to examine pharmacy professionals’ views regarding the future of PMHS.

Aim

To examine pharmacy professionals’ perceptions of the future of PMHS, and develop recommendations for service improvement.

Methods

University ethics and Health Research Authority approval were obtained before commencement. Participants comprised pharmacy professionals from acute, mental health, specialist, and community NHS Trusts that provided a PMHS. Invitations to participate in an online qualitative survey and subsequent semi-structured telephone interview were sent via email to pharmacy services at all Trusts that provided a PMHS. Within the survey and the interview schedule was one question “How do you see patient medicines helplines at NHS Trusts developing in the future?” and only the data generated from this open-ended question were analysed for this study. Survey data were collected via SurveyMonkey (n=100). Individuals interested in participating in an interview contacted the research team, resulting in 34 interviews. Interviews were conducted from May-October 2018, and ranged from 16 to 53 minutes. Braun and Clarke’s inductive reflexive thematic analysis was used to analyse the data. Guidelines for enhancing the validity and trustworthiness of qualitative research were used.

Results

Two themes were generated from the survey and interviews. Enhancing value for service users identifies suggestions for improving the value of PMHS for service users. These include providing access methods beyond the telephone, and providing patients/carers with post-discharge follow-up calls from a pharmacist. Improving efficiency identifies that, in the future, and in line with NHS plans for efficiency and shared resources, PMHS may become centralised or provided by community pharmacies. Centralised services were considered to likely have more resources available to provide a patient medicines information service compared to hospital pharmacies. Participants often referred to the Carter report and sustainability and transformation plans, which promote the sharing of resources within regions. However, such a change was perceived to only increase efficiency if patient information can be shared between relevant healthcare settings.

Conclusion

PMHS are perceived by pharmacy professionals as likely to become centralised in the future (i.e., provided regionally or nationally) or provided by community pharmacies. This is dependent upon patients’ information being shared between hospitals and the centralised PMHS or pharmacies. To enhance the value of PMHS for service users, providers could establish other methods of access, such as email and video consultation. A limitation of this study is that it did not seek the perspectives of pharmacy professionals who do not provide a PMHS, other healthcare professionals, nor patients and carers. Considering the uncertainty around the future of PMHS, research should establish the best way to support all patients and carers regarding medicines following hospital discharge.

Tracking of Primary Human Hepatocytes with Clinical MRI: Initial Results with Tat-Peptide Modified Superparamagnetic Iron Oxide Particles

The transplantation of primary human hepatocytes is a promising approach in the treatment of specific liver diseases. However, little is known about the fate of the cells following application. Magnetic resonance imaging (MRI) could enable real-time tracking and long-term detection of transplanted hepatocytes. The use of superparamagnetic iron oxide particles as cellular contrast agents should allow for the non-invasive detection of labelled cells on high-resolution magnetic resonance images. Experiments were performed on primary human hepatocytes to transfer the method of detecting labelled cells via clinical MRI into human hepatocyte transplantation. For labelling, Tat-peptide modified nano-sized superparamagnetic MagForce particles were used. Cells were investigated via a clinical MR scanner at 3.0 Tesla and the particle uptake within single hepatocytes was estimated using microscopic examinations. The labelled primary human hepatocytes were clearly detectable by MRI, proving the feasibility of this new concept. Therefore, this method is a useful tool to investigate the effects of human hepatocyte transplantation and to improve safety aspects of this method.

Diagnostic performance of cytology for assessment of hepatic lipid content in dairy cattle

The objective of our study was to characterize the diagnostic performance of cytology for assessing hepatic lipid content (HLC) in dairy cows by comparing microscopic evaluation of lipid vacuolation in touch imprint slide preparations of liver biopsies with quantitative measurement of triglyceride concentration ([TG]; mg/mg of wet weight) in paired biopsy samples. Our study also sought to compare the diagnostic performance of liver cytology, plasma nonesterified fatty acid concentration ([NEFA]), and plasma β-hydroxybutyrate concentration ([BHB]) derived from a measurement performed on whole blood, for assessing HLC. Chemical extraction of TG from liver tissue remains the gold standard for quantifying HLC, largely because available blood tests, although useful for detecting some types of pathology, such as increased lipid mobilization, ketosis, or hepatocellular injury, are nonspecific as to etiology. Veterinary practitioners can sample bovine liver for cytological evaluation in a fast, minimally invasive, and inexpensive manner. Thus, if highly predictive of HLC, cytology would be a practical diagnostic tool for dairy veterinarians. In our study, liver biopsy samples from Holstein cows (219 samples from 105 cows: 52 from cows 2 to 20 d prepartum, 105 from cows 0 to 10 d in milk, 62 from cows 18 to 25 d in milk) were used to prepare cytology slides and to quantify [TG] using the Folch extraction method followed by the Hantzch condensation reaction and spectrophotometric measurement. An ordinal scale (0-4) based on amount of hepatocellular cytoplasm occupied by discrete clear vacuoles was used by 3 blinded, independent observers to rank HLC in Wright-Giemsa-stained slides. Interobserver agreement in cytology scoring was good. Corresponding plasma [NEFA] and [BHB] measurements were available for 187 and 195 of the 219 samples, respectively. Liver [TG] correlated more strongly with cytology score than with NEFA or BHB, and receiver operating characteristic curve analysis showed that cytology had better diagnostic performance than either NEFA or BHB for correctly categorizing [TG] at thresholds of 5, 10, and 15%. Hepatic lipidosis in high-producing dairy cows is of major clinical and economic importance, and this study demonstrates that cytology is an accurate means of assessing HLC. Additional work is indicated to evaluate the diagnostic utility of liver cytology.

Antenatal Pertussis Vaccination: Why are General Practitioners Reluctant? A Mixed Methods StudySetting

Pertussis has a disproportionately higher morbidity and mortality in infants less than 3 months of age. International and national guidelines recommend pertussis vaccination during pregnancy, as a safe and effective way to protect these infants. Antenatal pertussis vaccination uptake rates remain suboptimal, with many health care professionals (HCPs) still not recommending it. The reasons underlying this reluctance on behalf of HCPs have not been fully established. This study aims to evaluate the current practice and attitudes of General Practitioners (GPs) with regard to antenatal pertussis vaccination. An embedded mixed method design was used. The response rate was 41% (n=109). 54% of GPs who responded (n=59) routinely recommend antenatal pertussis vaccination. Safety concerns and a sense of isolation emerged as the major qualitative themes. More safety data, adequate funding from the Health Service Executive (HSE) and support from secondary care may help to increase the GP recommendation rate and enhance vaccination uptake in pregnancy.

Risk factors associated with in-hospital mortality in elderly patients admitted to a regional trauma center after sustaining a fall

BACKGROUND AND AIMS

Falls are a significant cause of mortality in the elderly patients. Despite this, the literature on in-hospital mortality related to elderly falls remains sparse. Our study aims to determine the risk factors associated with in-hospital mortality in elderly patients admitted to a regional trauma center after sustaining a fall.

METHODS

All elderly case records with fall-related injuries between 2003 and 2013 were retrospectively analyzed for demographic characteristics, injury severities, comorbidity factors and clinical outcomes. Logistic regression analysis was used to examine the risk factors associated with in-hospital mortality.

RESULTS

In total, 1026 elderly patients with fall-related injuries were included in the study. The average age of patients was 80.94 ± 8.16 years. Seventy seven percent of the patients had at least one comorbid condition. Majority of the falls occurred at home. More than half of the patients fell from ground level. Overall, the in-hospital mortality rate was 16 %. Head injury constituted the most common injury sustained in patients who died (77 %). In addition to age, ISS, GCS, ICU admission and anemia were significantly (P < 0.05) associated with in-hospital deaths in elderly fall patients.

CONCLUSION

Ground-level falls in the elderly can be devastating and carry a significant mortality rate. Elderly patients with anemia were two times more likely to die in the hospital after sustaining a fall in our study population. Increased focus on anemia which is often underappreciated in elderly fall patients can be beneficial in improving outcomes and reducing in-hospital mortality.

Assessing the influence of component processing and donor characteristics on quality of red cell concentrates using quality control data

BACKGROUND AND OBJECTIVES

Quality control (QC) data collected by blood services are used to monitor production and to ensure compliance with regulatory standards. We demonstrate how analysis of quality control data can be used to highlight the sources of variability within red cell concentrates (RCCs).

MATERIALS AND METHODS

We merged Canadian Blood Services QC data with manufacturing and donor records for 28 227 RCC between June 2011 and October 2014. Units were categorized based on processing method, bag manufacturer, donor age and donor sex, then assessed based on product characteristics: haemolysis and haemoglobin levels, unit volume, leucocyte count and haematocrit.

RESULTS

Buffy-coat method (top/bottom)-processed units exhibited lower haemolysis than units processed using the whole-blood filtration method (top/top). Units from female donors exhibited lower haemolysis than male donations. Processing method influenced unit volume and the ratio of additive solution to residual plasma.

CONCLUSIONS

Stored red blood cell characteristics are influenced by prestorage processing and donor factors. Understanding the relationship between processing, donors and RCC quality will help blood services to ensure the safety of transfused products.

Medical service redesign shares the load saving 6000 bed days and improving morale

BACKGROUND AND AIMS

In 2010, demand on the Auckland City Hospital general medical service exceeded capacity. A review by the Royal Australasian College of Physicians was critical of training offered to registered medical officers, and low morale was a problem across the service. Management offered support for an improved model that would solve these problems.

METHODS

A project to redesign the general medical service was undertaken. Baseline analysis found uneven workload and insufficient capacity at peak times for patient presentations. Workshops involving the entire service led to a new model that splits workload and teams into patients likely to have a short stay from those requiring longer, ward-based care. Admissions are now distributed over 12 teams on weekdays and 4 on the weekends. There was an increase of approximately 2.5 in consultant full time equivalents but no change in registrar or house officer staffing.

RESULTS

Since the introduction of the new model, the average length of stay has fallen from 3.7 to 3.2 days (14%) and the median length of stay by 28%, resulting in a saving of 6000 bed days per year. Readmission, inpatient and 30-day mortality rates are unchanged. These results have been sustained over 18 months with signs of continuing improvement.

CONCLUSION

This project owes its success to the following factors - management support; iterative engagement of a range of staff; provision of timely data analysis; increases in senior medical officer staffing and reorganisation leading to more predictable and fair work practices. One challenge is discontinuity, whether between doctors and patients or within the medical team.

Variability of memory B cell markers in a cohort of common variable immune deficiency patients over 6 months

Common Variable Immunodeficiency Disorder (CVID) is a complex disorder that predisposes patients to recurrent and severe infections. Immunophenotypic classification schemes were developed to categorize patients with CVID into phenotypic and prognostic groups based on different memory B cell subsets. Whether the B cell subset analysis is stable over time has not been investigated. B cell phenotyping in patients with CVID (n = 15) and sex- and age-matched controls (n = 26) were carried out according to the three B cell classifications. Patients with CVID were evaluated monthly over 6 months. Controls were assessed once during the study. We scored how often each patient was assigned to the same group within each classification. The Freiburg classification assigned patients to the same group at a rate of 73% and the Paris classification at 88%. The EUROclass classification of smB- versus smB+ was at 90%. The two subclassifications [(smB-21low or smB-21norm) and transitional B] were at 87% and 97%, respectively. The level of naïve B cells measured in all patients with CVID during the 6-month evaluation was the most stable B cell subset. We conclude that all classifications systems show considerable variability, but the EUROclass classification was the most reliable scheme for our 15 CVID and 26 healthy cohorts. Our results indicate that phenotypic classifications within CVID will be difficult while there is variability of commonly used assays.

Critical research needs for managing coral reef marine protected areas: perspectives of academics and managers

Marine protected areas (MPAs) are a primary policy instrument for managing and protecting coral reefs. Successful MPAs ultimately depend on knowledge-based decision making, where scientific research is integrated into management actions. Fourteen coral reef MPA managers and sixteen academics from eleven research, state and federal government institutions each outlined at least five pertinent research needs for improving the management of MPAs situated in Australian coral reefs. From this list of 173 key questions, we asked members of each group to rank questions in order of urgency, redundancy and importance, which allowed us to explore the extent of perceptional mismatch and overlap among the two groups. Our results suggest the mismatch among MPA managers and academics is small, with no significant difference among the groups in terms of their respective research interests, or the type of questions they pose. However, managers prioritised spatial management and monitoring as research themes, whilst academics identified climate change, resilience, spatial management, fishing and connectivity as the most important topics. Ranking of the posed questions by the two groups was also similar, although managers were less confident about the achievability of the posed research questions and whether questions represented a knowledge gap. We conclude that improved collaboration and knowledge transfer among management and academic groups can be used to achieve similar objectives and enhance the knowledge-based management of MPAs.

Detection of isocyanates and polychlorinated biphenyls using proton transfer reaction mass spectrometry

RATIONALE

Isocyanates are highly reactive species widely used in industry. They can cause irritation of the eyes, trigger asthma, etc. Polychlorinated biphenyls (PCBs) were widely used in electrical equipments like capacitors and transformers in the last century and are still present in the environment today. PCBs are known to cause cancer and to affect the immune, reproductive, nervous and endocrine systems. Therefore, there is a need for a simple, rapid and reliable analytical method for the detection of traces of isocyanates and of PCBs.

METHODS

The data presented in this paper were obtained using a proton transfer reaction (PTR) time-of-flight mass spectrometer and a high sensitivity PTR quadrupole mass spectrometer. We also utilized a recently developed direct aqueous injection (DAI) inlet system for proton transfer reaction mass spectrometry (PTR-MS) instruments that allows the analysis of trace compounds in liquids.

RESULTS

We detected four isocyanates in the headspace above small sample quantities and investigated their fragmentation pathways to obtain a fundamental understanding of the processes involved in proton transfer reactions and also to determine the best operating conditions of the PTR-MS instruments. In addition, nine PCBs were unambiguously identified via their exact mass and isotopic distribution and detected in different concentration levels via direct injection of the liquid.

CONCLUSIONS

Utilizing recent developments and improvements in PTR-MS, we can rapidly detect two important environmental pollutant compound classes (isocyanates and PCBs) at high accuracy and without any sample preparation. In this paper, we provide proof of the detection of traces of isocyanates and PCBs in air and also of PCBs in liquids. These results could be used for the development of a real-time monitoring device for industrial waste, polluted air or water quality surveillance.
