Abstract
Background Tendinopathy is a common, painful and functionally limiting condition, primarily managed conservatively using exercise therapy. Review questions (i) What exercise interventions have been reported in the literature for which tendinopathies? (ii) What outcomes have been reported in studies investigating exercise interventions for tendinopathy? (iii) Which exercise interventions are most effective across all tendinopathies? (iv) Does type/location of tendinopathy or other specific covariates affect which are the most effective exercise therapies? (v) How feasible and acceptable are exercise interventions for tendinopathies? Methods A scoping review mapped exercise interventions for tendinopathies and outcomes reported to date (questions i and ii). Thereafter, two contingent systematic review workstreams were conducted. The first investigated a large number of studies and was split into three efficacy reviews that quantified and compared efficacy across different interventions (question iii), and investigated the influence of a range of potential moderators (question iv). The second was a convergent segregated mixed-method review (question v). Searches for studies published from 1998 were conducted in library databases (n = 9), trial registries (n = 6), grey literature databases (n = 5) and Google Scholar. Scoping review searches were completed on 28 April 2020 with efficacy and mixed-method search updates conducted on 19 January 2021 and 29 March 2021. Results Scoping review - 555 included studies identified a range of exercise interventions and outcomes across a range of tendinopathies, most commonly Achilles, patellar, lateral elbow and rotator cuff-related shoulder pain. Strengthening exercise was most common, with flexibility exercise used primarily in the upper limb. Disability was the most common outcome measured in Achilles, patellar and rotator cuff-related shoulder pain; physical function capacity was most common in lateral elbow tendinopathy. Efficacy reviews - 204 studies provided evidence that exercise therapy is safe and beneficial, and that patients are generally satisfied with treatment outcome and perceive the improvement to be substantial. In the context of generally low and very low-quality evidence, results identified that: (1) the shoulder may benefit more from flexibility (effect sizeResistance:Flexibility = 0.18 [95% CrI 0.07 to 0.29]) and proprioception (effect sizeResistance:Proprioception = 0.16 [95% CrI -1.8 to 0.32]); (2) when performing strengthening exercise it may be most beneficial to combine concentric and eccentric modes (effect sizeEccentricOnly:Concentric+Eccentric = 0.48 [95% CrI -0.13 to 1.1]; and (3) exercise may be most beneficial when combined with another conservative modality (e.g. injection or electro-therapy increasing effect size by ≈0.1 to 0.3). Mixed-method review - 94 studies (11 qualitative) provided evidence that exercise interventions for tendinopathy can largely be considered feasible and acceptable, and that several important factors should be considered when prescribing exercise for tendinopathy, including an awareness of potential barriers to and facilitators of engaging with exercise, patients' and providers' prior experience and beliefs, and the importance of patient education, self-management and the patient-healthcare professional relationship. Limitations Despite a large body of literature on exercise for tendinopathy, there are methodological and reporting limitations that influenced the recommendations that could be made. Conclusion The findings provide some support for the use of exercise combined with another conservative modality; flexibility and proprioception exercise for the shoulder; and a combination of eccentric and concentric strengthening exercise across tendinopathies. However, the findings must be interpreted within the context of the quality of the available evidence. Future work There is an urgent need for high-quality efficacy, effectiveness, cost-effectiveness and qualitative research that is adequately reported, using common terminology, definitions and outcomes.

Abstract
OBJECTIVE To investigate potential moderating effects of resistance exercise dose components including intensity, volume and frequency, for the management of common tendinopathies. DESIGN Systematic review with meta-analysis and meta-regressions. DATA SOURCES Including but not limited to: MEDLINE, CINAHL, SPORTDiscus, ClinicalTrials.gov and ISRCTN Registry. ELIGIBILITY CRITERIA FOR SELECTING STUDIES Randomised and non-randomised controlled trials investigating resistance exercise as the dominant treatment class, reporting sufficient information regarding ≥2 components of exercise dose. RESULTS A total of 110 studies were included in meta-analyses (148 treatment arms (TAs), 3953 participants), reporting on five tendinopathy locations (rotator cuff: 48 TAs; Achilles: 43 TAs; lateral elbow: 29 TAs; patellar: 24 TAs; gluteal: 4 TAs). Meta-regressions provided consistent evidence of greater pooled mean effect sizes for higher intensity therapies comprising additional external resistance compared with body mass only (large effect size domains: β BodyMass: External = 0.50 (95% credible interval (CrI): 0.15 to 0.84; p=0.998); small effect size domains (β BodyMass: External = 0.04 (95% CrI: -0.21 to 0.31; p=0.619)) when combined across tendinopathy locations or analysed separately. Greater pooled mean effect sizes were also identified for the lowest frequency (less than daily) compared with mid (daily) and high frequencies (more than once per day) for both effect size domains when combined or analysed separately (p≥0.976). Evidence for associations between training volume and pooled mean effect sizes was minimal and inconsistent. SUMMARY/CONCLUSION Resistance exercise dose is poorly reported within tendinopathy management literature. However, this large meta-analysis identified some consistent patterns indicating greater efficacy on average with therapies prescribing higher intensities (through inclusion of additional loads) and lower frequencies, potentially creating stronger stimuli and facilitating adequate recovery.

Archaeal Hel308 suppresses recombination through a catalytic switch that controls DNA annealing. Nucleic Acids Res 2023; 51:8563-8574. [PMID: 37409572 PMCID: PMC10484726 DOI: 10.1093/nar/gkad572] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/25/2023] [Revised: 06/14/2023] [Accepted: 06/23/2023] [Indexed: 07/07/2023] Open
Abstract
Hel308 helicases promote genome stability in archaea and are conserved in metazoans, where they are known as HELQ. Their helicase mechanism is well characterised, but it is unclear how they specifically contribute to genome stability in archaea. We show here that a highly conserved motif of Hel308/HELQ helicases (motif IVa, F/YHHAGL) modulates both DNA unwinding and a newly identified strand annealing function of archaeal Hel308. A single amino acid substitution in motif IVa results in hyper-active DNA helicase and annealase activities of purified Hel308 in vitro. All-atom molecular dynamics simulations using Hel308 crystal structures provided a molecular basis for these differences between mutant and wild type Hel308. In archaeal cells, the same mutation results in 160000-fold increased recombination, exclusively as gene conversion (non-crossover) events. However, crossover recombination is unaffected by the motif IVa mutation, as is cell viability or DNA damage sensitivity. By contrast, cells lacking Hel308 show impaired growth, increased sensitivity to DNA cross-linking agents, and only moderately increased recombination. Our data reveal that archaeal Hel308 suppresses recombination and promotes DNA repair, and that motif IVa in the RecA2 domain acts as a catalytic switch to modulate the separable recombination and repair activities of Hel308.

Patient ratings in exercise therapy for the management of tendinopathy: a systematic review with meta-analysis. Physiotherapy 2023; 120:78-94. [PMID: 37406460 DOI: 10.1016/j.physio.2023.05.002] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/24/2022] [Revised: 04/26/2023] [Accepted: 05/26/2023] [Indexed: 07/07/2023]
Abstract
OBJECTIVE To synthesise exercise therapy intervention data investigating patient rating outcomes for the management of tendinopathy. DESIGN A systematic review and meta-analysis of randomized controlled trials investigating exercise therapy interventions and reporting patient rating outcomes. SETTING Any setting in any country listed as very high on the human development index. PARTICIPANTS People with a diagnosis of any tendinopathy of any severity or duration. INTERVENTIONS Exercise therapy for the management of tendinopathy comprising five different therapy classes: 1) resistance; 2) plyometric; 3) vibration; 4) flexibility, and 5) movement pattern retraining modalities, were considered for inclusion. MAIN OUTCOME MEASURES Outcomes measuring patient rating of condition, including patient satisfaction and Global Rating of Change (GROC). RESULTS From a total of 124 exercise therapy studies, 34 (Achilles: 41%, rotator cuff: 32%, patellar: 15%, elbow: 9% and gluteal: 3%) provided sufficient information to be meta-analysed. The data were obtained across 48 treatment arms and 1246 participants. The pooled estimate for proportion of satisfaction was 0.63 [95%CrI: 0.53-0.73], and the pooled estimate for percentage of maximum GROC was 53 [95%CrI: 38-69%]. The proportion of patients reporting positive satisfaction and perception of change increased with longer follow-up periods from treatment onset. CONCLUSION Patient satisfaction and GROC appear similar and are ranked moderately high demonstrating that patients generally perceive exercise therapies positively. Further research including greater consistency in measurement tools is required to explore and where possible, identify patient- and exercise-related moderating factors that can be used to improve person-centred care.

Abstract
Objective To quantify and describe effect size distributions from exercise therapies across a range of tendinopathies and outcome domains to inform future research and clinical practice through conducting a systematic review with meta-analysis. Design Systematic review with meta-analysis exploring moderating effects and context-specific small, medium and large thresholds. Eligibility criteria Randomised and quasi-randomised controlled trials involving any persons with a diagnosis of rotator cuff, lateral elbow, patellar, Achilles or gluteal tendinopathy of any severity or duration. Methods Common databases, six trial registries and six grey literature databases were searched on 18 January 2021 (PROSPERO: CRD42020168187). Standardised mean difference (SMDpre) effect sizes were used with Bayesian hierarchical meta-analysis models to calculate the 0.25 (small), 0.5 (medium) and 0.75 quantiles (large) and compare pooled means across potential moderators. Risk of bias was assessed with Cochrane's Risk of Bias tool. Results Data were obtained from 114 studies comprising 171 treatment arms 4104 participants. SMDpre effect sizes were similar across tendinopathies but varied across outcome domains. Greater threshold values were obtained for self-reported measures of pain (small=0.5, medium=0.9 and large=1.4), disability (small=0.6, medium=1.0 and large=1.5) and function (small=0.6, medium=1.1 and large=1.8) and lower threshold values obtained for quality of life (small=-0.2, medium=0.3 and large=0.7) and objective measures of physical function (small=0.2, medium=0.4 and large=0.7). Potential moderating effects of assessment duration, exercise supervision and symptom duration were also identified, with greater pooled mean effect sizes estimated for longer assessment durations, supervised therapies and studies comprising patients with shorter symptom durations. Conclusion The effect size of exercise on tendinopathy is dependent on the type of outcome measure assessed. Threshold values presented here can be used to guide interpretation and assist with further research better establishing minimal important change.

Abstract
Abstract
Introduction
Syncope is a common clinical problem with a lifetime prevalence of 20%.1 Syncope shares clinical features with other disorders including seizures, metabolic disturbances and sleep disorders.2 The assessment and management of syncope can be challenging. The syncope service at the QEUH is run by geriatricians and cardiologists with an interest in syncope. Although MDTs are recognised key components in contemporary patient care in areas such as heart failure and cancer management, there is no guidance on MDT working in syncope management.3/4 In November 2017, a syncope MDT was introduced at the QEUH involving cardiologists, geriatricians, a neurologist and cardiac physiologists. This in-person MDT occurs monthly with outcomes recorded on electronic medical records in addition to a database. The aim of this review was to understand the potential impact of the MDT on diagnostic yield and time to further investigation or management.
Method
A retrospective case note analysis was performed for patients reviewed at the Syncope MDT between November 2017 and December 2021.
Results
103 patients were discussed with an average age of 64 years. The main reason for referral was cardiology specialist advice (65%), neurology specialist advice (19.4%) and complex case review (13.6%). After MDT discussion, the percentage of patients with unexplained TLoC reduced from 26.2% to 14.6% without requirement for additional investigations. 8.7% of patients were started on anti-epileptic medication prior to outpatient neurology review after a diagnosis of seizure disorder was established and 23.1% of patients were streamlined for pacemaker or ILR insertion.
Conclusion
Introduction of a syncope MDT reduces unexplained syncope rates in complex patients, streamlines investigations, reduces the need for multi-speciality outpatient reviews and allows earlier introduction of anti-epileptic medication for those with a new seizure disorder. These benefits improve the patient experience by reducing time to diagnosis and treatment.

Abstract
Abstract
Introduction
Comprehensive Geriatric Assessment (CGA) improves outcomes for frail older adults in acute hospitals. Patients aged 75 and over admitted into the Emergency Department (ED) at the QEUH will automatically generate a “frailty icon” on their electronic record. The number of frail people accessing emergency care is increasing. This Healthcare Improvement Scotland (HIS) frailty tool prompts staff to assess for frailty and refer to the local Frailty Pathway if appropriate. We designed a multidisciplinary quality improvement project (QIP) to increase completion of the frailty icon and the number of referrals to the frailty service from the ED.
Methods
Both medical and nursing staff in the ED were targeted for intervention. Weekly data was collected on the percentage of patients aged 75 and above who were discharged from the ED with a “frailty icon” completed over a 3-month period. Our main intervention was to hold a frailty awareness month. This involved multiple sub-interventions such as; announcements at handovers, e-mails, word-of-mouth, and posters.
Results
The weekly percentage of completed “frailty icons” increased from 28% 2 weeks pre-intervention (n = 283) to 48% in 1 month (n = 258). A peak of 57% (n = 293) completed icons was achieved immediately after our intervention. These increases were then sustained for a further 6 weeks with a weekly average baseline of 45.2% completion (average n = 281). Increased “frailty icon” completion in the ED led to a 100% increase in referrals to the frailty pathway.
Conclusion
Increasing awareness of frailty amongst ED staff results in increased front door assessment for frailty, and subsequent referral to the frailty team. This allows for more patients to receive a CGA. Multidisciplinary QIPs utilise the skills of diverse staff groups to best achieve sustainable change.

Abstract
Abstract
Background
Guidelines for the management of pulmonary arterial hypertension (PAH) recommend early combination therapy of an endothelial receptor antagonist (ERA) and a phosphodiesterase type-5 inhibitor (PDE5i) [1]. There is, however, limited guidance about the management of PAH patients with comorbidities.
Purpose
To describe the demographics, clinical characteristics, safety, tolerability, and outcomes associated with initiation of the ERA macitentan and the PDE5i tadalafil in patients with comorbidities in the US OPsumit® USers (OPUS) and the OPsumit® Historical USers cohort (OrPHeUS) combined dataset.
Methods
This analysis reports data from the OPUS registry (Apr 2014–Jun 2020) and OrPHeUS medical chart review (Oct 2013–Mar 2017) on PAH patients initiating macitentan and tadalafil (M+T) combination therapy, in any order, as concomitant initiation (≤60 days apart, concomitant initiation group). The index date was defined as the start date of the second therapy (i.e., the start of combination therapy). Patients were further grouped by the number of comorbidities present prior to or at macitentan initiation: systemic hypertension, diabetes, renal insufficiency, BMI ≥30 kg/m2, other signs of right heart failure and atrial fibrillation. Results are presented descriptively alongside results for all PAH patients receiving M+T combination therapy (overall M+T group).
Results
Of the 1336 PAH patients that received M+T combination therapy, 431 (32%) were in the concomitant initiation group. In the concomitant initiation and overall M+T groups, respectively: 72% and 68% had ≥1 comorbidity, and the most common were systemic hypertension (47% and 47%), obesity (32% and 26%) and diabetes (23% and 22%). Patients were more likely to be older, male and have idiopathic/heritable PAH with increasing comorbidity burden (Table 1). Patients in the concomitant initiation group were more likely to be incident (median time from diagnosis: 1–2 months vs 9–24 months in the overall M+T group; Table 1). Most patients had ≥1 adverse event (AE); in both groups, patients with a high comorbidity burden (≥3) were more likely to have had an AE and to have discontinued treatment (Table 2). The incidence rate of first all-cause hospitalisation and mortality by comorbidity was comparable between the concomitant initiation and overall M+T groups.
Conclusions
In the real-world, concomitant initiation of M+T is used in PAH patients with comorbidities, usually shortly after diagnosis. Patient characteristics were similar for the concomitant initiation and overall M+T groups, with the exception of time from diagnosis. At index date, age, gender proportion, and PAH aetiology differed between the comorbidity groups. The safety profile of M+T combination therapy in the concomitant initiation group was consistent with that in the overall M+T group.

Abstract
Importance The durability of the antibody response to COVID-19 vaccines in patients with cancer undergoing treatment or who received a stem cell transplant is unknown and may be associated with infection outcomes. Objective To evaluate anti-SARS-CoV-2 spike protein receptor binding domain (anti-RBD) and neutralizing antibody (nAb) responses to COVID-19 vaccines longitudinally over 6 months in patients with cancer undergoing treatment or who received a stem cell transplant (SCT). Design, Setting, and Participants In this prospective, observational, longitudinal cross-sectional study of 453 patients with cancer undergoing treatment or who received an SCT at the University of Kansas Cancer Center in Kansas City, blood samples were obtained before 433 patients received a messenger RNA (mRNA) vaccine (BNT162b2 or mRNA-1273), after the first dose of the mRNA vaccine, and 1 month, 3 months, and 6 months after the second dose. Blood samples were also obtained 2, 4, and 7 months after 17 patients received the JNJ-78436735 vaccine. For patients receiving a third dose of an mRNA vaccine, blood samples were obtained 30 days after the third dose. Interventions Blood samples and BNT162b2, mRNA-1273, or JNJ-78436735 vaccines. Main Outcomes and Measures Geometric mean titers (GMTs) of the anti-RBD; the ratio of GMTs for analysis of demographic, disease, and treatment variables; the percentage of neutralization of anti-RBD antibodies; and the correlation between anti-RBD and nAb responses to the COVID-19 vaccines. Results This study enrolled 453 patients (mean [SD] age, 60.4 [13,1] years; 253 [56%] were female). Of 450 patients, 273 (61%) received the BNT162b2 vaccine (Pfizer), 160 (36%) received the mRNA-1273 vaccine (Moderna), and 17 (4%) received the JNJ-7846735 vaccine (Johnson & Johnson). The GMTs of the anti-RBD for all patients were 1.70 (95% CI, 1.04-2.85) before vaccination, 18.65 (95% CI, 10.19-34.11) after the first dose, 470.38 (95% CI, 322.07-686.99) at 1 month after the second dose, 425.80 (95% CI, 322.24-562.64) at 3 months after the second dose, 447.23 (95% CI, 258.53-773.66) at 6 months after the second dose, and 9224.85 (95% CI, 2423.92-35107.55) after the third dose. The rate of threshold neutralization (≥30%) was observed in 203 of 252 patients (80%) 1 month after the second dose and in 135 of 166 patients (81%) 3 months after the second dose. Anti-RBD and nAb were highly correlated (Spearman correlation coefficient, 0.93 [0.92-0.94]; P < .001). Three months after the second dose, anti-RBD titers were lower in male vs female patients (ratio of GMTs, 0.52 [95% CI, 0.34-0.81]), patients older than 65 years vs patients 50 years or younger (ratio of GMTs, 0.38 [95% CI, 0.25-0.57]), and patients with hematologic malignant tumors vs solid tumors (ratio of GMTs, 0.40 [95% CI, 0.20-0.81]). Conclusions and Relevance In this cross-sectional study, after 2 doses of an mRNA vaccine, anti-RBD titers peaked at 1 month and remained stable over the next 6 months. Patients older than 65 years of age, male patients, and patients with a hematologic malignant tumor had low antibody titers. Compared with the primary vaccine course, a 20-fold increase in titers from a third dose suggests a brisk B-cell anamnestic response in patients with cancer.

Abstract
Introduction Patient and public involvement (PPI) in suicide research is ethical, moral and can deliver impact. However, inconsistent reporting of meaningful PPI, and hesitancy in sharing power with people with experience of suicidality (i.e.co-researchers) in research makes it difficult to understand the full potential impact of PPI on the research, researchers and co-researchers. Objectives To describe how our ecological momentary assessment (EMA) study, examining the sleep-suicide relationship in young psychiatric inpatients (aged 18-35) transitioning to the community, has been co-produced, whilst reflecting on impact, challenges, and recommendations. Methods We built on our experience of co-produced mental health research to conduct meaningful PPI in our study. Young adults with experience of psychiatric inpatient care and suicidality were appointed November 2020 to work across all research stages. Reflections on challenges, recommendations and impact have been collected throughout. Results Three young people became co-researchers. Researcher and co-researcher reflections indicated establishing and maintaining safe environments for open discussion, and continued communication (e.g.WhatsApp group) were vital to effectively share power and decision making. Safeguarding and support requirements for both co-researchers (e.g.individualised strategy) and researcher (e.g.clinical supervision) were particularly evident. To date, the co-produced recruitment poster, research documentation, and research article have demonstrated significant impact. Conclusions This is the first EMA study focused on suicide-sleep during transitions to be co-produced with young people with experience of suicidality. Co-producing suicide research is intensive, time-consuming, and challenging but makes a significant impact to the research, researchers, and co-researchers. We expect our learning will directly influence, and help others produce, meaningful co-produced suicide research. Disclosure No significant relationships.

Abstract
Abstract
Introduction
OH is a disabling condition resulting from a sustained reduction in blood pressure (>20 systolic or 10 diastolic) within 3 minutes of standing. It is a common cause of syncope. Patients with concurrent hypertension experiencing syncope present a complex management dilemma where a balance must be established between symptom burden and risk of cardiovascular disease. Current guidance on ABPM use in syncope is limited. European society of cardiology syncope guidelines suggest ABPM in patients with ‘autonomic failure’ to assess nocturnal hypertension or drug-induced hypotension. Could this be improved with further explicit criteria on which patients to assess and how to act on results? The objective of this study is to review the use of 24 hour ABPM in OH within a tertiary referral syncope clinic.
Method
A retrospective analysis was performed electronically for patients with a final diagnosis of OH seen in a syncope clinic between March 2017 and May 2019. Data was collected on comorbidities, medication history, physical mobility, clinic blood pressure, ABPM Results: (if performed) and medication changes. Comparisons were made between patients who had ABPM and those who did not. Statistics were calculated using Fisher’s Exact Test (2 tailed).
Results
119 patients had a final diagnosis of OH in the study period. 45 had ABPM, 74 did not. The ABPM group had a significantly higher proportion of diagnosed hypertension (51.1% vs 23% (p = 0.0025)). A similar proportion of patients in both groups had medication changed however the ABPM group were significantly more likely to have antihypertensive therapy added (19.4% vs 1.8% (p = 0.0053)).
Conclusion
Using 24 hour ABPM in OH patients can aid clinical decision making in the sub-group with hypertension. This can guide the need for alteration/addition of antihypertensive therapy to balance optimum BP control with symptom burden.

Abstract
Abstract
Background: Infection with SARS-CoV-2 has led to a global pandemic and has significantly impacted the care of cancer patients. Breast cancer patients receiving active systemic therapy need protection against COVID19 but the efficacy of vaccines in this population is unknown. Although specific biomarkers associated with protection from SARS-CoV-2 infection have yet to be identified, measurement of serum antibody activity is generally accepted as a surrogate of in vivo humoral response to vaccine. This study evaluates the efficiency and durability of binding antibodies to SARS-CoV-2 spike (S) protein in response to COVID19 vaccine in breast cancer patients receiving systemic treatment. Methods: Breast cancer patients, who were unvaccinated, partially or fully vaccinated with Pfizer-BioNTech BNT162b2 (PF), Moderna mRNA-1273 (Mod) or Johnson & Johnson AD26.COV2.S (J&J) were enrolled in this prospective longitudinal study. Eligible patients were on systemic treatment with cytotoxic chemotherapy, chemotherapy plus a checkpoint inhibitor (CPI), CPI alone or a CDK 4/6 inhibitor. Longitudinal blood samples are being collected at baseline, prior to vaccination in unvaccinated patients (T0), 2 weeks after the first vaccine dose and before the second dose for the mRNA vaccines (T1), 1 month (T2), 3 months (T3), 6 months (T4) and 12 month post vaccination. For J&J, there was no T1 timepoint. Roche Elecsys® Anti-SARS-CoV-2 S receptor binding domain (RBD) antibody immunoassay was used to measure antibody titers (range 0.4 to 250 U/mL). Cut points of <0.8 U/mL = negative, ≥0.8 U/mL = seropositive, were based on validated product specifications. Results: Of the 84 breast cancer patients enrolled, 9 had documented COVID infection at baseline and were excluded from analysis. Mean age was 58 years; 99% were female, 85% were Caucasian, 49% had early stage disease and 51% had metastatic breast cancer. 67% were receiving cytotoxic chemotherapy, 20% a CKD 4/6 inhibitor, 13% a CPI with or without chemotherapy. 61.2% were vaccinated with PF, 34.3% with Mod and 4.5% with J&J vaccines. Seropositivity rate for the entire group was 10% at T0, 78% at T1, 98% at T2 and 100% at T3. Seropositivity rates of all cohorts at different timepoints are shown in the table. Mean titers for all patients were 12.6 U/mL at T0, 102.3 U/mL at T1, 204.4 U/mL at T2 and 214.6 U/mL at T3 timepoints. Similar incremental increase in antibody levels was observed in all cohorts (Table). Conclusions: 78% of the patients with breast cancer on active systemic treatment were seropositive after the first dose of COVID19 vaccine and 98% after the second dose. The antibody response was maintained at 3 months, with 100% seropositivity rate. 6-month antibody response will be available at the time of presentation. Durability of antibody response at 6 and 12 months will help determine the timing of additional vaccine booster doses in this population. Importantly, this study has found that active treatment with chemotherapy, immunotherapy or CDK4/6 inhibitor therapy does not impact antibody response to SARS-CoV-2 vaccination in patients with breast cancer. Table: Seropositivity rate and mean Anti-S protein antibody levels by cohort at each time point. T0= baseline, T1=after first vaccine dose (mRNA vaccines), T2= 4 weeks after 2 doses of mRNA vaccine or after single dose of J&J vaccine, T3=3 months after the first dose of vaccine.

Abstract
Abstract
Background
In PAH clinical practice, drugs targeting the prostacyclin pathway, including the oral prostacyclin receptor agonist selexipag, are often initiated years after diagnosis. The GRIPHON (NCT01106014) and TRITON (NCT02558231) randomised controlled trials examined the impact of selexipag on disease progression, primary and secondary endpoints, respectively. In GRIPHON, selexipag significantly reduced the risk of disease progression (composite primary endpoint) in a PAH population (N=1156) with a mean time from diagnosis of 2.4 years, as part of an oral triple, double or monotherapy regimen versus placebo. In TRITON, a potential signal for reduced risk of disease progression was observed with initial triple oral therapy (selexipag, macitentan, tadalafil) versus initial double oral therapy (placebo, macitentan, tadalafil) in a population of 247 newly diagnosed, treatment naïve patients.
Purpose
To investigate the impact of initiating selexipag within 6 months of diagnosis on disease progression in a large PAH population.
Methods
We selected patients from GRIPHON and TRITON diagnosed within 6 months of randomization and compared those on active therapy with selexipag (selexipag group) versus those on control therapy with placebo (control group). Disease progression endpoints were defined as in the GRIPHON and TRITON studies, respectively. Hazard ratios (HR) and 95% CI for time to first disease progression event up to end of double-blind treatment (selexipag/placebo) + 7 days were estimated using a Cox regression model which included treatment as a factor, and baseline prognostic factors and study as covariates.
Results
Overall, 649 patients met the criteria (diagnosis ≤6 months) for these analyses: 329 in the selexipag group (207 from GRIPHON and 122 from TRITON) and 320 in the control group (197 from GRIPHON and 123 from TRITON). Patient characteristics at baseline and treatment regimens were balanced between the treatment groups. With respect to treatment regimen, selexipag/placebo was given as part of triple therapy in 44%, double therapy in 32% and monotherapy in 24% of patients. The median (range) exposure to study treatment was 510 (4–1280) and 409 (3–1318) days in the selexipag and control groups, respectively. There were 67 (20%) and 116 (36%) patients who experienced a disease progression event in the selexipag and control groups, respectively. Selexipag reduced the risk of disease progression (first event) by 52% compared to control (HR 0.48 [95% CI 0.35, 0.66]) (Figure).
Conclusions
This post-hoc pooled analysis of GRIPHON and TRITON patients diagnosed within 6 months suggests that targeting the prostacylin pathway with selexipag within a short time after diagnosis may reduce the risk of disease progression in a broad PAH population.

Abstract
BACKGROUND UK adult gender identity clinics (GICs) are implementing a new streamlined service model. However, there is minimal evidence from these services underpinning this. It is also unknown how many service users subsequently 'detransition'. AIMS To describe service users' access to care and patterns of service use, specifically, interventions accessed, reasons for discharge and re-referrals; to identify factors associated with access; and to quantify 'detransitioning'. METHOD A retrospective case-note review was performed as a service evaluation for 175 service users consecutively discharged by a tertiary National Health Service adult GIC between 1 September 2017 and 31 August 2018. Descriptive statistics were used for rates of accessing interventions sought, reasons for discharge, re-referral and frequency of detransitioning. Using multivariate analysis, we sought associations between several variables and 'accessing care' or 'other outcome'. RESULTS The treatment pathway was completed by 56.1%. All interventions initially sought were accessed by 58%; 94% accessed hormones but only 47.7% accessed gender reassignment surgery; 21.7% disengaged; and 19.4% were re-referred. Multivariate analysis identified coexisting neurodevelopmental disorders (odds ratio [OR] = 5.7, 95% CI = 1.7-19), previous adverse childhood experiences (ACEs) per reported ACE (OR = 1.5, 95% CI = 1.1-1.9), substance misuse during treatment (OR = 4.3, 95% CI = 1.1-17.6) and mental health concerns during treatment (OR = 2.2, 95% CI 1.1-4.4) as independently associated with accessing care. Twelve people (6.9%) met our case definition of detransitioning. CONCLUSIONS Service users may have unmet needs. Neurodevelopmental disorders or ACEs suggest complexity requiring consideration during the assessment process. Managing mental ill health and substance misuse during treatment needs optimising. Detransitioning might be more frequent than previously reported.

Abstract
Sclerosing epithelioid fibrosarcoma (SEF) is a rare and aggressive soft-tissue sarcoma thought to originate in fibroblasts of the tissues comprising tendons, ligaments, and muscles. Minimally responsive to conventional cytotoxic chemotherapies, >50% of SEF patients experience local recurrence and/or metastatic disease. SEF is most commonly discovered in middle-aged and elderly adults, but also rarely in children. A common gene fusion occurring between the EWSR1 and CREB3L1 genes has been observed in 80%–90% of SEF cases. We describe here the youngest SEF patient reported to date (a 3-yr-old Caucasian male) who presented with numerous bony and lung metastases. Additionally, we perform a comprehensive literature review of all SEF-related articles published since the disease was first characterized. Finally, we describe the generation of an SEF primary cell line, the first such culture to be reported. The patient described here experienced persistent disease progression despite aggressive treatment including multiple resections, radiotherapy, and numerous chemotherapies and targeted therapeutics. Untreated and locally recurrent tumor and metastatic tissue were sequenced by whole-genome, whole-exome, and deep-transcriptome next-generation sequencing with comparison to a patient-matched normal blood sample. Consistent across all sequencing analyses was the disease-defining EWSR1–CREB3L1 fusion as a single feature consensus. We provide an analysis of our genomic findings and discuss potential therapeutic strategies for SEF.

Pragmatic mAb lead molecule engineering from a developability perspective. Biotechnol Bioeng 2021; 118:3733-3743.

Abstract
As the number of antibody drugs being approved and marketed increases, our knowledge of what makes potential drug candidates a successful product has increased tremendously. One of the critical parameters that have become clear in the field is the importance of mAb "developability." Efforts are being increasingly focused on simultaneously selecting molecules that exhibit both desirable biological potencies and manufacturability attributes. In the current study mutations to improve the developability profile of a problematic antibody that inconsistently precipitates in a batch scale-dependent fashion using a standard platform purification process are described. Initial bioinformatic analysis showed the molecule has no obvious sequence or structural liabilities that might lead it to precipitate. Subsequent analysis of the molecule revealed the presence of two unusual positively charged mutations on the light chain at the interface of VH and VL domains, which were hypothesized to be the primary contributor to molecule precipitation during process development. To investigate this hypothesis, straightforward reversion to the germline of these residues was carried out. The resulting mutants have improved expression titers and recovered stability within a forced precipitation assay, without any change to biological activity. Given the time pressures of drug development in industry, process optimization of the lead molecule was carried out in parallel to the "retrospective" mutagenesis approach. Bespoke process optimization for large-scale manufacturing was successful. However, we propose that such context-dependent sequence liabilities should be included in the arsenal of in silico developability screening early in development; particularly since this specific issue can be efficiently mitigated without the requirement for extensive screening of lead molecule variants.

The utility of coronary artery calcium in non-gated high resolution CT thorax scans in predicting cardiac events as compared to the Framingham risk score: a retrospective study. Eur Heart J 2020.

Abstract
Abstract
Background
There is existing evidence to suggest a correlation between coronary artery calcification (CAC) measured using ECG-triggered chest computed tomography and cardiovascular disease. Further evidence has emerged to suggest a correlation between CAC measured using non-gated CT scans and cardiovascular disease. Herein, we sought to ascertain the utility of incidental findings of CAC on non-triggered high resolution CT (HRCT) thorax used for patients undergoing lung cancer screening or follow-up for interstitial lung disease and Framingham risk score (FRS) in predicting cardiovascular events.
Methods
The Computerised Radiology Information Service (CRIS) database was manually searched to determine all HRCT scans performed in a single trust from 05/2015 to 05/2016. The reports issued by Radiologists and images of selected studies were reviewed. For patients with CAC, we calculated the calcium score for patients using the Agatston method. Clinical events were determined from the electronic medical record without knowledge of patients' CAC findings. For these patients, the Framingham Risk Score (FRS) was also calculated. The primary end point of the study was composite of all-cause mortality and cardiac events (non-fatal myocardial infarction, coronary revascularization, new atrial fibrillation or heart failure episode requiring hospitalization).
Results
We selected 300 scans from a total of approximately 2000 scans performed over this time. Data at follow up was available for 100% of the patients, with a median duration of follow up of 1.6 years. Moderate to severe CAC was found in 35% of people. Multivariable analysis showed good concordance between CAC and FRS in predicting composite clinical end point. The Odds Ratio for cardiac events in patients with moderate to severe CAC was 5.3 (p<0.01) and for composite clinical end point was 3.4 (p<0.01). This is similar to the OR predicted by the FRS: 4.8; p<0.01 and 3.1; p<0.01 respectively. Only 6.2% of patients with moderate to severe CAC were currently statin treated.
Conclusion
In this retrospective study of patients with respiratory disease attending for HRCT scanning, co-incidentally detected CAC predicts cardiac events, with good concordance with the FRS. The incidental finding of CAC on non-gated CT scanning should be reported with Agatston score calculation allowing consideration of intervention to mitigate cardiovascular risk and optimize. Further multi-centre prospective studies of this strategy, with a larger patient cohort should be conducted to clarify the utility of CAC as a prediction tool to modify cardiac risk.

Abstract
Survivors of adolescent and young adult cancers (AYAs) often live 50 to 60 years beyond their diagnosis. This rapidly growing cohort is at increased risk for cancer- and treatment-related 'late effects' that persist for decades into survivorship. Recognition of similar issues in pediatric cancer survivors has prompted the development of evidence-based guidelines for late effects screening and care. However, corresponding evidence-based guidelines for AYAs have not been developed. We hosted an AYA survivorship symposium for a large group of multidisciplinary AYA stakeholders (approximately 200 were in attendance) at Princess Margaret Cancer Centre (Toronto, Ontario, Canada) to begin addressing this disparity. The following overview briefly summarizes and discusses the symposium's stakeholder-identified high-priority targets for late effects screening and care and highlights knowledge gaps to direct future research in the field of AYA survivorship. This overview, although not exhaustive, is intended to stimulate clinicians to consider these high-priority screening and care targets when seeing survivors in clinical settings and, ultimately, to support the development of evidence-based late effects screening and care guidelines for AYAs.

Abstract
Accurate measurement of naturally occurring radionuclides in blast furnace slag, a by-product of the steel industry, is required for compliance with building regulations where it is often used as an ingredient in cement. A matrix reference blast furnace slag material has been developed to support traceability in these measurements. Raw material provided by a commercial producer underwent stability and homogeneity testing, as well as characterisation of matrix constituents, to provide a final candidate reference material. The radionuclide content was then determined during a comparison exercise that included 23 laboratories from 14 countries. Participants determined the activity per unit mass for 226Ra, 232Th and 40K using a range of techniques. The consensus values obtained from the power-moderated mean of the reported participant results were used as indicative activity per unit mass values for the three radionuclides: A0(226Ra) = 106.3 (34) Bq·kg-1, A0(232Th) = 130.0 (48) Bq·kg-1 and A0(40K) = 161 (11) Bq·kg-1 (where the number in parentheses is the numerical value of the combined standard uncertainty referred to the corresponding last digits of the quoted result). This exercise helps to address the current shortage of NORM industry reference materials, putting in place infrastructure for production of further reference materials.

Abstract
Abstract
Background
Deficiency of the lysosomal enzyme galactosylcerebrosidase (GALC) causes Krabbe disease. The diagnosis for Krabbe disease includes measurement of GALC enzymatic activity by radioisotope assay or accumulation of metabolite psychosine. To improve current diagnostic workflow and assay performance, we developed and validated a leukocyte enzymatic assay by using liquid chromatography tandem mass spectrometry (LC-MS/MS) for lysosomal storage diseases.
Methods
Leukocytes were separated and extracted from whole blood samples, and total protein was quantitated by BCA method. Commercialized and multiplexed substrates, internal standards, and buffer were incubated with cell lysates. The lysosomal enzymes in leukocytes metabolized the artificial substrate into product which is structurally identical to the internal standard. Liquid-liquid extraction was performed and supernatant was dried down and reconstituted. Liquid chromatography separation was achieved by Waters CSH C18, 2.1 x 50 mm column and Acquity UPLC system. A Waters Xevo TQS tandem mass spectrometer was used for mass detection.
Results
Enzymatic reaction products for six lysosomal enzymes were chromatographically resolved from substrate breakdown products through 3.5 minutes gradient liquid chromatography. Intra-assay imprecision was determined by 11 replicates of samples containing low and high concentration (CV<15%). Carryover was determined by assaying triplicates of cell lysate-free cocktails directly after injection of high enzyme activity sample (less than 0.1%). No matrix effect was found. The GALC enzyme activity was calculated and standardized by corresponding product and internal standard ratios from 5-point standard curve. The range of enzyme activity from three, known affected patients is 0.01–0.07 (nmol/hr/mg protein); whereas, two identified carriers had enzyme activate in the range of 0.14–0.40 (nmol/hr/mg protein). The reference interval was established from 63 residual, unaffected samples and was 0.12–5.97 (1.44±1.44) nmol/hr/mg protein.
Conclusions
A simple and multiplexed LC-MS/MS assay was developed which can measure small amounts of residual GALC enzyme activity in leukocytes. This confirmatory assay will aid in the diagnosis and prognosis (i.e. differentiate disease severity) of Krabbe disease and other lysosomal storage disorders.

Abstract
Abstract
Background: Immunotherapy targeting co-stimulatory receptors of T cells is under active clinical investigation. Inducible co-stimulator (ICOS) is an important co-stimulatory receptor on effector T cells (Teffs) that also promotes tumor growth due to its high expression on regulatory T cells (Tregs). Human IgG1 anti-ICOS therapeutic antibodies may therefore induce antitumor immunity by stimulating ICOSLow Teffs and depleting ICOSHigh Tregs. This study explored the clinical significance of ICOS expression and Treg content in hepatocellular carcinoma (HCC).
Patients and Methods: We collected tumor tissues from HCC patients who received curative hepatectomy at the National Taiwan University Hospital, Taipei, Taiwan. Dual immunohistochemistry (IHC) was performed to evaluate the expression of ICOS and Foxp3. The cell density and distances between single- and dual-expressing cells in the tumor center, margin, and the peritumor area were quantitated by digital pathology. Associations between clinical outcome or clinical metadata and ICOS/Foxp3 expression were analyzed.
Results: A total of 142 patients (male: female= 112: 30, median age of 61.0 years) were enrolled. Among them, 87 (61.3%) had chronic hepatitis B virus (HBV) infection, 33 (23.2%) had chronic hepatitis C (HCV) infection, and 22 (15.5%) had no HBV/HCV infection. In this cohort, low AFP level (< 20 ng/ml) and early stage, but not age, gender, or viral etiology, were significantly associated with improved overall survival (OS). However, the density of ICOS+Foxp3+ cells and the ratio of ICOS+Foxp3+/total Foxp3+ cells were significantly higher (p<0.001) in the tumor center than in the peritumor area especially in viral-related HCC. Similarly, patients with a high ratio of ICOS+Foxp3+/total Foxp3+ cells (p=0.074) or with high ICOS expression (p<0.05) in the tumor center were associated with a shorter OS. Finally, a shorter distance between ICOS+Foxp3+ cells and ICOS+Foxp3- cells in the tumor center was significantly associated with a shorter OS (p<0.05) suggesting active immunosuppression of ICOS+ Tregs on ICOS+ Teff cells.
Conclusions: A high proportion of Tregs in HCC tumors expresses ICOS, implying a strong immunosuppressive environment. Importantly, high ICOS expression in HCC tumors, a high ratio of ICOS+Foxp3+/total Foxp3+ cells and a shorter distance between ICOS+ Tregs and other ICOS+ cells are all associated with a poor OS, suggesting that targeting ICOS in this indication may provide clinical benefit (This work is partly supported by MOST 108-2314-B-002-073).

Recommended Personal Protective Equipment for Cochlear Implant and Other Mastoid Surgery During the COVID-19 Era. Laryngoscope 2020; 130:2693-2699. [PMID: 32720316 DOI: 10.1002/lary.29014] [Citation(s) in RCA: 6] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/03/2020] [Revised: 07/10/2020] [Accepted: 07/21/2020] [Indexed: 12/31/2022]
Abstract
OBJECTIVES/HYPOTHESIS The overall aim of this study was to evaluate personal protective equipment (PPE) that may facilitate the safe recommencement of cochlear implantation in the COVID-19 era, with the broader goal of minimizing the period of auditory deprivation in prelingually deaf children and reducing the risk of cochlear ossification in individuals following meningitis. METHODS The study design comprised 1) an objective assessment of mastoid drilling-induced droplet spread conducted during simulated cochlear implant (CI) surgery and its mitigation via the use of a protective drape tent and 2) an evaluation of three PPE configurations by otologists while performing mastoid drilling on ex vivo temporal bones. The various PPE solutions were assessed in terms of their impact on communication, vital physiological parameters, visual acuity and fields, and acceptability to surgeons using a systematic risk-based approach. RESULTS Droplet spread during simulated CI surgery extended over 2 m, a distance greater than previously reported. A drape tent significantly reduced droplet spread. The ensemble of a half-face mask and safety spoggles (foam lined safety goggles) had consistently superior performance across all aspects of clinical usability. All other PPE options were found to substantially restrict the visual field, making them unsafe for microsurgery. CONCLUSIONS The results of this preclinical study indicate that the most viable solution to enable the safe conduct of CI and other mastoid surgery is a combination of a filtering facepiece (FFP3) mask or half-face respirator with safety spoggles as PPE. Prescription spoggles are an option for surgeons who need to wear corrective glasses to operate. A drape tent reduces droplet spread. A multicenter clinical trial to evaluate the effectiveness of PPE should be the next step toward safely performing CI surgery during the COVID-19 era. LEVEL OF EVIDENCE 4 Laryngoscope, 130:2693-2699, 2020.

Inter-Relationships between Frailty, Sarcopenia, Undernutrition and Dysphagia in Older People Who Are Admitted to Acute Frailty and Medical Wards: Is There an Older Adult Quartet? Geriatrics (Basel) 2020; 5:geriatrics5030041. [PMID: 32630034 PMCID: PMC7555188 DOI: 10.3390/geriatrics5030041] [Citation(s) in RCA: 6] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/04/2020] [Revised: 06/17/2020] [Accepted: 06/23/2020] [Indexed: 11/16/2022] Open
Abstract
Introduction: With increasing age the prevalence of frailty, sarcopenia, undernutrition and dysphagia increases. These are all independent markers of outcome. This study explores the prevalence of these four and explores relationships between them. Methods: A convenience sample of 122 patients admitted to acute medical and frailty wards were recruited. Each was assessed using appropriate screening tools; Clinical Frailty Score (CFS) for frailty, SARC-F for sarcopenia, Nutritional Risk Tool (NRT) for nutritional status and 4QT for dysphagia. Results: The mean age of the participants was 80.53 years (65–99 years), and 50.37% (68) were female. Overall, 111 of the 122 (91.0%) reported the presence of at least one of the quartet. The median CFS was 5 (1–9), with 84 patients (68.9%) having a score of ≥5 (moderate or severely frail); The median SARC-F was 5 (0–10), with 64 patients (52.5%) having a score of ≥5; The median NRT was 0 (0–8) and 33 patients (27.0%) scored ≥ 1. A total of 77 patients (63.1%) reported no difficulty with swallowing/dysphagia (4QT ≥ 1) and 29 (23.7%) had only one factor. Sixteen patients (13.1%) had all four. There was a significant correlation between nutritional status and dysphagia, but not with frailty or sarcopenia. There were significant correlations between frailty and both sarcopenia and dysphagia. Conclusions: In our sample of acute medical and frailty ward patients, there was a much higher prevalence than expected (91%) of either: frailty, sarcopenia, undernutrition or dysphagia. The prevalence of all four was present in 13% of patients. We suggest that frailty, sarcopenia, nutritional risk and dysphagia comprise an “Older Adult Quartet”. Further study is required to investigate the effect of the “Older Adult Quartet” on morbidity and mortality.

Abstract
PURPOSE: Participation in cancer clinical trials (CCTs) for adolescents and young adults (AYAs) remains the lowest of any patient group with cancer. Little is known about the personal barriers to AYA accrual. The aim of this study was to explore AYA attitudes that influence CCT participation. METHODS: A mixed-methods approach was used. AYAs and non-AYAs (≥ 40 years) completed the Cancer Treatment subscale of the Attitudes Toward Cancer Trials Scales and 9 supplementary questions formed from interview analysis. Differences between AYA and non-AYA cohorts were analyzed using the Mann-Whitney U test, and logistic regression models were constructed to evaluate the effect of demographics on perceptions of CCTs. RESULTS: Surveys were distributed to 61 AYAs (median age, 29 years; range, 17-39 years) and 74 non-AYAs (median age, 55 years; range, 40-88 years). Compared with non-AYAs, AYAs perceived CCTs to be unsafe/more difficult (Personal Barrier/Safety domain; P = .01). There were no differences based on age in other domains. AYAs were also more concerned with CCT interference in their long-term goals ( P = .04). Multivariable ordered logistic regression identified increased personal barriers in the Personal Barrier/Safety domain for AYAs ( P = .01), in patients with English as a second language (ESL; P < .01), and in patients previously not offered a clinical trial ( P = .03). Long-term goals were identified as a barrier in particular tumor types ( P = .01) and in patients with ESL ( P < .01), with a trend identified in AYAs ( P = .12). CONCLUSION: Age-related differences in attitudes toward CCTs suggest that tailored approaches to CCT accrual are warranted. Patient-centered delivery of information regarding CCTs, particularly in patients with ESL and who are trial naïve, may improve accrual.

Abstract
Abstract
A method for determining methyl mercury in fish and shellfish was collaboratively studied in 8 laboratories. Methyl mercury is isolated from acetonewashed, homogenized tissue by adding hydrochloric acid and extracting into benzene the methyl mercuric chloride that is formed. The benzene extract is concentrated and analyzed for methyl mercuric chloride by electron capture gas-liquid chromatography on 5% DEGS-PS treated with inorganic mercuric chloride solution. The quantitation limit for the method is 0.05 μg Hg/g. Each collaborator determined methyl mercury at 2 levels in blind duplicate samples of swordfish, tuna, oyster, and shrimp tissues. Both fortified and unfortified samples were analyzed. Methyl-bound mercury in the samples ranged from 0.15 to 148 μg Hg/g. The reproducibility coefficients of variation for the 8 samples ranged from 3 to 13%. The accuracy, measured by comparison to reference values, ranged from 99 to 120%. Reference values were determined in the Associate Referee's laboratory by replicate analyses of the fortified and unfortified samples. The method has been adopted official first action.

Abstract
Adolescents and young adults (AYAs) with cancer aged 15-39 years have unique medical, psychosocial, and informational needs. At the time of diagnosis, they are often going through important life milestones, such as establishing their independence, attending school or work, and maintaining romantic and/or family relationships. This article describes some of the critical time points for AYAs with cancer and the resources available to support the nursing profession in meeting the unique care needs of this population.

Abstract
e18021 Background: Women with cancer risk premature ovarian insufficiency with implications for future fertility due to chemotherapy and radiotherapy. Still, infertility discussions are inconsistently provided. Options for egg cryopreservation exist for females, but discussing these topics can be overwhelming for patients and families. This paper aims to assess the understandability, actionability, and readability of a fertility preservation (FP) educational video, as well as patient (pt) and caregiver pre- and post-video perceptions and knowledge. Methods: A video was created by the institution's Adolescent and Young Adult Program to explain relevant anatomy, pathophysiology of ovulation and process of cryopreservation. Understandability and actionability were evaluated using the Patient Education Materials Assessment Tool for Audiovisual Materials (PEMAT-AV) and readability using the SMOG and Flesch-Kincaid indices. Pt perceptions and knowledge growth were captured using pre-post questionnaires. Female pts (n = 108) were recruited in oncology clinics over 2 months, using a convenience sample. Questionnaire responses were analyzed using SPSS to calculate descriptive statistics to conduct correlation analyses. Results: The median age of the participants was 28 (range 14-39 yrs). The average PEMAT-A/V score was 79% (±11.3%) for understandability and 72% (±13.1%) for actionability. A score of 70% is regarded as acceptable. The readability assessment determined that the video script was, on average, at a grade 8 reading level. Pts’ interest in learning about FP increased, with 14% of those initially uninterested or unsure wanting to learn more after viewing the video. Pts’ general knowledge on FP increased from the pre- to post-video questionnaire, from a mean score of 75% initially (±17.9%), to a mean score of 84% (±14.5%) after watching the video (t = -5.972, p = 0.000). On average, overall satisfaction with the video was 85% (±8.5%). Conclusions: Women commonly use online tools for researching health questions. This study demonstrates that the video is understandable and provides guidance for future discussion. It shows that videos can spark interest in sensitive discussions and can improve fertility knowledge. This video may encourage providers to more consistently initiate discussions about infertility. Furthermore, the video can be translated for related topics to help provide accurate information in a patient-friendly medium.

Abstract
PURPOSE Fertility is an important issue for adolescents and young adults with cancer facing potential infertility. Egg cryopreservation options exist, but information is sometimes overwhelming. We evaluated a fertility preservation educational video and assessed patient and family knowledge and impressions at pre- and post-video timepoints. METHODS We developed a whiteboard video to explain egg cryopreservation to patients and families. The video was evaluated on the basis of patient education best practices (readability, understandability, actionability). Participants were recruited using convenience sampling in oncology clinics. They completed questionnaires before and after watching to assess knowledge and interest. Inclusion criteria were patients age 13-39 years and minimum 1 month from diagnosis. Descriptive statistics, correlation analyses, and mean comparisons were conducted. RESULTS The video script read at a grade 8 reading level. Average understandability and actionability scores were below the acceptable standard. We recruited 108 patients (mean age, 27 years) and 39 caregivers/partners. Patients' knowledge about fertility preservation increased after viewing the video. Interest was high before and after, and satisfaction was high for both patients and caregivers. Participants appreciated information on process, procedure, and delivery but desired more information on logistics, including cost. CONCLUSION A targeted patient education video about fertility preservation options can build knowledge and encourage discussions about infertility. The video can be used as a model for videos on related topics to provide accurate information in a youth-friendly medium; however, following patient education best practices for readability, understandability, and actionability may increase video effectiveness. Future research should assess how audiovisual patient education material affects patient behavior.

Abstract
BACKGROUND Primary healthcare dietitians have a vital role to play in the prevention and management of chronic disease. Working in primary care requires efficient and effective management of practice to ensure client and practitioner needs are met. The present study aimed to explore the way in which primary care dietitians in Australia view the constructs of efficiency and effectiveness within the context of their practice. METHODS The study used an exploratory qualitative design within a pragmatist framework. Individual semi-structured telephone interviews were conducted with Australian primary care dietitians. All interviews were audio-recorded, transcribed verbatim and analysed using an inductive thematic approach. RESULTS Twenty dietitians (17 females) working as private practitioners in primary care from three Australian states participated in the present study. Three themes emerged from the data. The first theme revealed that seeking efficiency and especially effectiveness were important to primary care dietitians and that there was a tension between the two. The second theme identified that efficiency and effectiveness are influenced by personal and structural factors. The final theme explored how dietitians are actively seeking ways to be more efficient and effective, including supportive networks, as well as the utilisation of technology. CONCLUSIONS Achieving a balance between efficiency and effectiveness in primary care dietetics is challenging to practitioners, who may require further training and support to enhance productivity, time management and resource utilisation. Structured issues exist for the workface. Further studies are required to quantify these findings and to explore whether it is possible to optimise efficiency and effectiveness and achieve sustainability of the dietetic workforce in primary care.
