The implementation of a hepatitis C testing service in community pharmacies: I-COPTIC consensus statement. Public Health 2024; 232:153-160. [PMID: 38781782 DOI: 10.1016/j.puhe.2024.04.017] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/20/2023] [Revised: 03/21/2024] [Accepted: 04/09/2024] [Indexed: 05/25/2024]
Abstract
OBJECTIVES This aimed to develop a blueprint for an effective community pharmacy Hepatitis C virus (HCV) testing service by producing a consensus statement. STUDY DESIGN This was a modified Delphi process. METHODS We recruited a heterogenous panel of experts (who had been involved in the setup or delivery of a community pharmacy HCV testing service) by purposive and chain referral methods. We had three rounds of a modified Delphi process. The first was a series of questions with free text responses and was analysed using thematic analysis, and the second and third were statements for the respondents to rate using a 7-point Likert scale. Consensus was predefined in a published protocol, and the results were reviewed by a public and patient involvement panel before the statement was finalised. RESULTS We had 24 participants, including community and hospital-based pharmacists, local pharmaceutical committee members, charity representatives (Hepatitis C Trust), local clinical service lead, nurse specialists and doctors. The response rate of the first, second and third rounds were 100%, 96% and 88%, respectively. After the third round, we had 60 statements that reached consensus. We discussed the accepted statements with a patient and public involvement group. We used these statements to produce the I-COPTIC statement and a graphical summary. CONCLUSIONS We developed a blueprint for the design of a gold standard community pharmacy HCV testing service. We believe this will support the successful implementation of community pharmacy testing for HCV. Community pharmacy testing is an important service to help achieve and maintain HCV elimination.

Comparing environmental impacts of deep-seabed and land-based mining: A defensible framework. GLOBAL CHANGE BIOLOGY 2024; 30:e17334. [PMID: 38780465 DOI: 10.1111/gcb.17334] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Subscribe] [Scholar Register] [Received: 10/25/2023] [Revised: 03/23/2024] [Accepted: 03/29/2024] [Indexed: 05/25/2024]
Abstract
The crises of climate change and biodiversity loss are interlinked and must be addressed jointly. A proposed solution for reducing reliance on fossil fuels, and thus mitigating climate change, is the transition from conventional combustion-engine to electric vehicles. This transition currently requires additional mineral resources, such as nickel and cobalt used in car batteries, presently obtained from land-based mines. Most options to meet this demand are associated with some biodiversity loss. One proposal is to mine the deep seabed, a vast, relatively pristine and mostly unexplored region of our planet. Few comparisons of environmental impacts of solely expanding land-based mining versus extending mining to the deep seabed for the additional resources exist and for biodiversity only qualitative. Here, we present a framework that facilitates a holistic comparison of relative ecosystem impacts by mining, using empirical data from relevant environmental metrics. This framework (Environmental Impact Wheel) includes a suite of physicochemical and biological components, rather than a few selected metrics, surrogates, or proxies. It is modified from the "recovery wheel" presented in the International Standards for the Practice of Ecological Restoration to address impacts rather than recovery. The wheel includes six attributes (physical condition, community composition, structural diversity, ecosystem function, external exchanges and absence of threats). Each has 3-5 sub attributes, in turn measured with several indicators. The framework includes five steps: (1) identifying geographic scope; (2) identifying relevant spatiotemporal scales; (3) selecting relevant indicators for each sub-attribute; (4) aggregating changes in indicators to scores; and (5) generating Environmental Impact Wheels for targeted comparisons. To move forward comparisons of land-based with deep seabed mining, thresholds of the indicators that reflect the range in severity of environmental impacts are needed. Indicators should be based on clearly articulated environmental goals, with objectives and targets that are specific, measurable, achievable, relevant, and time bound.

Patterns of evolution in MHC class II DQA and DQB exon 2 genes of Alpine mountain hares, Lepus timidus varronis, and sympatric and parapatric brown hares, L. europaeus, from Switzerland.

Abstract
In natural populations, hybridization is known to occur between a wide range of species. However, its evolutionary significance is less clear. Genes involved in fighting pathogens are considered excellent candidates for studying adaptive introgression, although both introgression and balancing selection can generate similar patterns of diversity and differentiation. Here, we compared DQA and DQB MHC class II and microsatellite allelic diversity of sympatric and parapatric mountain (Lepus timidus) and brown hare (L. europaeus) populations from Switzerland. We detected higher genetic diversity in brown hares compared to mountain hares at both MHC and microsatellite loci. We consider the observed patterns of microsatellite diversity both for L. europaeus and L. timidus as result of stochastic demographic processes while the pattern of MHC polymorphism of the studied hare populations can be explained by pathogen-driven selection. Rare bidirectional gene flow between both hare species seems to occur specifically for MHC alleles. However, the high number of shared alleles showing similar high frequency in both species suggests that reciprocally exchanged MHC alleles are being maintained via balancing selection. Adaptation to similar pathogen communities can also lead to parallel selection of MHC alleles. Positive selection, recombination and mutations have played different roles in shaping the patterns of MHC allelic diversity in and differentiation between both species. Results for the latter evolutionary forces do not show a better matching between the sympatric populations compared to the parapatric ones, suggesting a minor role of introgression for the observed evolutionary patterns of the studied hare species.

Abstract
PURPOSE/OBJECTIVE(S) Rehabilitation services for recovery of impaired physical function following breast cancer treatments are largely underutilized. We previously found that breast cancer survivors treated with radiation who received higher radiation doses to the pectoralis major are more likely to self-report shoulder pain and disability. This study aims to address whether radiation dose delivered to the pectoralis major (Pmaj) and pectoralis minor (Pmin) are correlated with referrals for rehabilitation services post-treatment. MATERIALS/METHODS A retrospective 1:1 matched case-control study was conducted for breast cancer patients who were and were not referred for breast or shoulder rehabilitation services between 2014-2019 at a single academic institution. Patients were included if they had a lumpectomy and adjuvant radiation without regional nodal irradiation. Cohorts were matched based on age, axillary surgery (none vs. sentinel lymph node biopsy (SLNB)), and use of radiation boost. We used non-parametric Mann-Whitney U tests to determine whether Pmaj or Pmin doses (mean, V50Gy, V45Gy, V40Gy, V35Gy, V30Gy, V20Gy) were different between the two groups. Muscle doses were converted to EQD2 assuming an α/β ratio of 2.5. RESULTS In our study of 30 patients of a median age 57 years (IQR 12.75), 20 (66.67%) patients underwent SLNB in addition to lumpectomy. Median tumor size was 1.1cm (range 0.16 - 7.30cm). Stage was 0 for 11 patients (36.67%), I for 14 patients (46.67%), and II for 5 patients (16.67%). 3D conformal radiation was delivered to the whole breast with a moderately hypofractionated (n = 17) or conventionally fractionated regimen (n = 13). The most common rehabilitation diagnoses were lymphedema (n = 8), scar management (n = 7) and shoulder pain (n = 5). Mean dose to both the Pmaj (20.8Gy vs. 18.6Gy; p = 0.02) and Pmin (30.6Gy vs. 24.6Gy; p = 0.01) were significantly higher in patients who received post-treatment rehabilitation compared to those without. The V40Gy, V35Gy, V30Gy and V20Gy (all p<0.02) for the Pmin and V35Gy, V30Gy and V20Gy for the Pmaj (all p<0.04) were also significantly higher in those who underwent rehabilitation. CONCLUSION In this cohort of patients with early-stage breast cancer, increased mean doses to the pectoralis muscles were correlated with increased use of rehabilitation services after radiation. Physicians might consider using these dosimetric data to complement clinical symptoms in the decision-making process for referrals for rehabilitation services. This may help facilitate earlier referral to rehabilitation interventions, which is important since early intervention is correlated with improved shoulder morbidity.

Abstract
INTRODUCTION The COVID-19 pandemic is a global public health emergency. Lockdown restrictions and the reconfiguration of healthcare systems to accommodate an increase in critical care capacity have had an impact on 'non-COVID' specialties. This study characterises the utilisation of emergency general surgery (EGS) services during the UK lockdown period at a university teaching hospital with a catchment population that represents one of the most deprived and ethnically diverse areas in the UK. METHODS EGS admissions during the UK lockdown period (March to May 2020) were compared with the same period in 2019. Patient demographics were recorded together with clinical presentation, hospital stay and treatment outcomes, and readmission data. RESULTS The study included 645 patients, comprising 223 in the COVID-19 period and 422 in the non-COVID-19 period. There was no difference in age, sex, comorbidity or socio-economic status. A lower proportion of patients of Black, Asian and Minority Ethnicity (BAME) were admitted during the pandemic (20.6% vs 35.4%, p < 0.05). The duration of symptoms prior to presentation was longer, and admission clinical parameters and serum inflammatory markers. More patients presented with an acute kidney injury (9.9% vs 4.7%, p = 0.012). There was no difference in perioperative outcomes or 30-day mortality, but more patients were readmitted following conservative management (10.6% vs 4.7%, p = 0.023). CONCLUSIONS The reorganisation of EGS to a senior-led model has been successful in terms of outcomes and access to treatment despite a more unwell population. There was a significantly lower proportion of BAME admissions suggesting additional barriers to healthcare access under pandemic lockdown conditions.

Abstract
Importance Involvement of palliative care specialists in the care of medical oncology patients has been repeatedly observed to improve patient-reported outcomes, but there is no analogous research in surgical oncology populations. Objective To determine whether surgeon-palliative care team comanagement, compared with surgeon team alone management, improves patient-reported perioperative outcomes among patients pursuing curative-intent surgery for high morbidity and mortality upper gastrointestinal (GI) cancers. Design, Setting, and Participants From October 20, 2018, to March 31, 2022, a patient-randomized clinical trial was conducted with patients and clinicians nonblinded but the analysis team blinded to allocation. The trial was conducted in 5 geographically diverse academic medical centers in the US. Individuals pursuing curative-intent surgery for an upper GI cancer who had received no previous specialist palliative care were eligible. Surgeons were encouraged to offer participation to all eligible patients. Intervention Surgeon-palliative care comanagement patients met with palliative care either in person or via telephone before surgery, 1 week after surgery, and 1, 2, and 3 months after surgery. For patients in the surgeon-alone group, surgeons were encouraged to follow National Comprehensive Cancer Network-recommended triggers for palliative care consultation. Main Outcomes and Measures The primary outcome of the trial was patient-reported health-related quality of life at 3 months following the operation. Secondary outcomes were patient-reported mental and physical distress. Intention-to-treat analysis was performed. Results In total, 359 patients (175 [48.7%] men; mean [SD] age, 64.6 [10.7] years) were randomized to surgeon-alone (n = 177) or surgeon-palliative care comanagement (n = 182), with most patients (206 [57.4%]) undergoing pancreatic cancer surgery. No adverse events were associated with the intervention, and 11% of patients in the surgeon-alone and 90% in the surgeon-palliative care comanagement groups received palliative care consultation. There was no significant difference between study arms in outcomes at 3 months following the operation in patient-reported health-related quality of life (mean [SD], 138.54 [28.28] vs 136.90 [28.96]; P = .62), mental health (mean [SD], -0.07 [0.87] vs -0.07 [0.84]; P = .98), or overall number of deaths (6 [3.7%] vs 7 [4.1%]; P > .99). Conclusions and Relevance To date, this is the first multisite randomized clinical trial to evaluate perioperative palliative care and the earliest integration of palliative care into cancer care. Unlike in medical oncology practice, the data from this trial do not suggest palliative care-associated improvements in patient-reported outcomes among patients pursuing curative-intent surgeries for upper GI cancers.

Abstract
BACKGROUND There is a growing number of patients with ventricular paced rhythm, who present to the emergency department with chest pain. The diagnosis of ST-segment elevation myocardial infarction (STEMI) and subsequent percutaneous coronary intervention (PCI) is often postponed, as the 12 leads-electrocardiogram (ECG) is discarded as not interpretable. There is a growing body of literature that suggests that Smith-modified Sgarbossa criteria can be applied for the diagnosis of STEMI in patients with paced rhythms. These criteria were originally developed for the interpretation of ECGs in patients with a left bundle branch block (LBBB) and chest pain, but have been expanded to paced ECGs. METHODOLOGY We present three case reports with chest pain and right ventricular or biventricular pacing. FINDINGS In all three cases, the Smith-modified Sgarbossa was positive and the diagnosis of STEMI could have been made early on. IMPLICATIONS It remains important to look for ST-segment deviations and to compare the symptomatic ECG with previous asymptomatic ECGs. As the number of patients with potential acute myocardial infarction (AMI) and paced rhythms is likely to rise in the future, these criteria should be known to emergency physicians and cardiologists.

Abstract
The study aims to characterise the species identification and antimicrobial susceptibility testing (AST) results of Nocardial isolates from adult patients across major public hospitals in Queensland, Australia, over a 15-year period. A multi-centre retrospective observational study of Nocardia sp. isolates was conducted from 7 major public hospitals in Queensland, Australia, over a 15-year period. Clinical samples from patients aged ≥ 18 years that isolated Nocardia sp. were included. Demographic and clinical data were collected, along with species identification and AST results. Overall, 484 Nocardia sp. were isolated. Most patients were male (297, 61%) with a mean (IQR) age of 60 (51-75) and a median (IQR) Charlson Comorbidity Index of 4 (2-6). Of these, 239 (49%) patients were immunosuppressed. Organisms were most frequently isolated from sputum (174, 36%), and superficial swabs (102, 21%). Patients presented with pulmonary infections (165, 35%) and superficial skin and soft tissue infections (87, 18%) most commonly. One hundred (21%) isolates were deemed pulmonary colonisation and were not treated. Of the speciated organisms, N. nova complex was the most common (93, 19%), followed by N. farcinica complex (79, 16%). Organisms were reliably susceptible to linezolid (240/245, 98%), amikacin (455/470, 97%), and trimethoprim/sulfamethoxazole (459/476, 96%), but less so to imipenem (243/472, 51%) and ceftriaxone (261/448, 58%). This is the largest Australian description of Nocardia sp. to date. Given antimicrobials are often commenced prior to AST results and sometimes even speciation, characterisation of local species and antibiogram data is important to guide empiric choices and local guidelines.

Access to Results of Patient Reported Outcome Surveys Does Not Improve Survey Response Rates. J Surg Res 2023; 283:945-952.

Abstract
INTRODUCTION In this embedded substudy of a longitudinal, randomized controlled trial, we sought to evaluate the effects of patient engagement and results feedback on longitudinal patient-reported outcome (PRO) survey completion rates. METHODS Newly diagnosed stage 0-III breast cancer patients seen at an academic breast center between June 2019 and December 2021 were invited to participate in a longitudinal PRO study. Participants were emailed the BREAST-Q survey, a validated PRO scale, preoperatively and at regular intervals during their postoperative course. Patients were randomized into the intervention group, who received survey results upon completion, or the control group, who received no feedback. The primary endpoint was postoperative survey completion rate. An intention to treat analysis was performed and a quasi-Poisson regression was used to compare rates of longitudinal survey completion between the two groups. RESULTS Of the 253 patients offered the preoperative survey, 115 were in the intervention group and 138 were in the control group. Postoperative survey completion rate was 54% for the intervention group and 47% for the control group. There was no significant difference in longitudinal postoperative survey completion rate between the two groups (rate ratio 1.10; 95% confidence interval [CI] 0.93-1.31). CONCLUSIONS In this prospective randomized controlled study, patients did not complete surveys at a higher rate when their survey results were shared with them, suggesting that viewing these results without appropriate clinical context does not generate significant enhancement in patient engagement. Effective interventions to improve survey response rate must be identified to better evaluate PROs.

Safety and efficacy of tenecteplase in patients with wake-up stroke assessed by non-contrast CT (TWIST): a multicentre, open-label, randomised controlled trial. Lancet Neurol 2023; 22:117-126. [PMID: 36549308 DOI: 10.1016/s1474-4422(22)00484-7] [Citation(s) in RCA: 14] [Impact Index Per Article: 14.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/20/2022] [Revised: 11/18/2022] [Accepted: 11/21/2022] [Indexed: 12/24/2022]
Abstract
BACKGROUND Current evidence supports the use of intravenous thrombolysis with alteplase in patients with wake-up stroke selected with MRI or perfusion imaging and is recommended in clinical guidelines. However, access to advanced imaging techniques is often scarce. We aimed to determine whether thrombolytic treatment with intravenous tenecteplase given within 4·5 h of awakening improves functional outcome in patients with ischaemic wake-up stroke selected using non-contrast CT. METHODS TWIST was an investigator-initiated, multicentre, open-label, randomised controlled trial with blinded endpoint assessment, conducted at 77 hospitals in ten countries. We included patients aged 18 years or older with acute ischaemic stroke symptoms upon awakening, limb weakness, a National Institutes of Health Stroke Scale (NIHSS) score of 3 or higher or aphasia, a non-contrast CT examination of the head, and the ability to receive tenecteplase within 4·5 h of awakening. Patients were randomly assigned (1:1) to either a single intravenous bolus of tenecteplase 0·25 mg per kg of bodyweight (maximum 25 mg) or control (no thrombolysis) using a central, web-based, computer-generated randomisation schedule. Trained research personnel, who conducted telephone interviews at 90 days (follow-up), were masked to treatment allocation. Clinical assessments were performed on day 1 (at baseline) and day 7 of hospital admission (or at discharge, whichever occurred first). The primary outcome was functional outcome assessed by the modified Rankin Scale (mRS) at 90 days and analysed using ordinal logistic regression in the intention-to-treat population. This trial is registered with EudraCT (2014-000096-80), ClinicalTrials.gov (NCT03181360), and ISRCTN (10601890). FINDINGS From June 12, 2017, to Sept 30, 2021, 578 of the required 600 patients were enrolled (288 randomly assigned to the tenecteplase group and 290 to the control group [intention-to-treat population]). The median age of participants was 73·7 years (IQR 65·9-81·1). 332 (57%) of 578 participants were male and 246 (43%) were female. Treatment with tenecteplase was not associated with better functional outcome, according to mRS score at 90 days (adjusted OR 1·18, 95% CI 0·88-1·58; p=0·27). Mortality at 90 days did not significantly differ between treatment groups (28 [10%] patients in the tenecteplase group and 23 [8%] in the control group; adjusted HR 1·29, 95% CI 0·74-2·26; p=0·37). Symptomatic intracranial haemorrhage occurred in six (2%) patients in the tenecteplase group versus three (1%) in the control group (adjusted OR 2·17, 95% CI 0·53-8·87; p=0·28), whereas any intracranial haemorrhage occurred in 33 (11%) versus 30 (10%) patients (adjusted OR 1·14, 0·67-1·94; p=0·64). INTERPRETATION In patients with wake-up stroke selected with non-contrast CT, treatment with tenecteplase was not associated with better functional outcome at 90 days. The number of symptomatic haemorrhages and any intracranial haemorrhages in both treatment groups was similar to findings from previous trials of wake-up stroke patients selected using advanced imaging. Current evidence does not support treatment with tenecteplase in patients selected with non-contrast CT.

Abstract
Purpose To evaluate the perception of physicians at satellite offices of a large academic ophthalmology department. Methods A survey was sent to the 32 physician faculty members working at the satellite offices in the Ophthalmology Department of the University of Michigan. The ophthalmologists answered 44 survey questions on staffing, wait times, physician satisfaction, patient satisfaction, compensation, administrative help, research, and operations management. Results Seventeen (53%) satellite ophthalmologists responded. The majority were satisfied with work at satellites, which they felt operated efficiently and believed to feature high patient satisfaction. A minority of ophthalmologists had concerns about salary, volume, marketing support, and geographic location. Some respondents did not understand the compensation structure, satellites' finances, or contribution to the overall department. Most described a lack of research and resident teaching opportunities at satellites. Conclusions The perceptions of ophthalmologists who work in satellite offices are important because of the growth of these offices in academic medical centers and the ability for satellite doctors to offer care comparable with and sooner than doctors at the main hospital at locations convenient for patients. Satellite ophthalmologists at this academic center would appreciate increased transparency of compensation and financial structures; administrative help with marketing and maintaining efficiency, which doctors and patients enjoy at satellite offices; and more teaching and research opportunities, which are the basis of academic advancement. Such efforts may help retain satellite doctors, who tend to be junior in rank, female, nontenured faculty, and who experience a higher turnover rate than faculty at the main campus.

Harmonising knee pain patient-reported outcomes: a systematic literature review and meta-analysis of Patient Acceptable Symptom State (PASS) and individual participant data (IPD). Osteoarthritis Cartilage 2023; 31:83-95. [PMID: 36089231 DOI: 10.1016/j.joca.2022.08.011] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/24/2022] [Revised: 08/10/2022] [Accepted: 08/16/2022] [Indexed: 02/02/2023]
Abstract
OBJECTIVE In order to facilitate data pooling between studies, we explored harmonisation of patient-reported outcome measures (PROMs) in people with knee pain due to osteoarthritis or knee trauma, using the Patient Acceptable Symptom State scores (PASS) as a criterion. METHODS We undertook a systematic literature review (SLR) of PASS scores, and performed individual participant data (IPD) analysis of score distributions from concurrently completed PROM pairs. Numerical rating scales (NRS), visual analogue scales, KOOS and WOMAC pain questionnaires were standardised to 0 to 100 (worst) scales. Meta-regression explored associations of PASS. Bland Altman plots compared PROM scores within individuals using IPD from WebEx, KICK, MenTOR and NEKO studies. RESULTS SLR identified 18 studies reporting PASS in people with knee pain. Pooled standardised PASS was 27 (95% CI: 21 to 35; n = 6,339). PASS was statistically similar for each standardised PROM. Lower PASS was associated with lower baseline pain (β = 0.49, P = 0.01) and longer time from treatment initiation (Q = 6.35, P = 0.04). PASS scores were lowest in ligament rupture (12, 95% CI: 11 to 13), but similar between knee osteoarthritis (31, 95% CI: 26 to 36) and meniscal tear (27, 95% CI: 20 to 35). In IPD, standardised PROMs each revealed similar group mean scores, but scores within individuals diverged between PROMs (LoA between -7 to -38 and +25 to 52). CONCLUSION Different standardised PROMs give similar PASS thresholds in group data. PASS thresholds may be affected more by patient and treatment characteristics than between PROMs. However, different PROMs give divergent scores within individuals, possibly reflecting different experiences of pain.

Abstract
AIMS The European Society of Cardiology (ESC) EURObservational Research Programme (EORP) Non-ST-segment elevation myocardial infarction (NSTEMI) Registry aims to identify international patterns in NSTEMI management in clinical practice and outcomes against the 2015 ESC Guidelines for the management of acute coronary syndromes in patients presenting without ST-segment-elevation. METHODS AND RESULTS Consecutively hospitalised adult NSTEMI patients (n = 3620) were enrolled between 11 March 2019 and 6 March 2021, and individual patient data prospectively collected at 287 centres in 59 participating countries during a two-week enrolment period per centre. The registry collected data relating to baseline characteristics, major outcomes (in-hospital death, acute heart failure, cardiogenic shock, bleeding, stroke/transient ischaemic attack, and 30-day mortality) and guideline-recommended NSTEMI care interventions: electrocardiogram pre- or in-hospital, pre-hospitalization receipt of aspirin, echocardiography, coronary angiography, referral to cardiac rehabilitation, smoking cessation advice, dietary advice, and prescription on discharge of aspirin, P2Y12 inhibition, angiotensin converting enzyme inhibitor (ACEi)/angiotensin receptor blocker (ARB), beta-blocker, and statin. CONCLUSION The EORP NSTEMI Registry is an international, prospective registry of care and outcomes of patients treated for NSTEMI, which will provide unique insights into the contemporary management of hospitalised NSTEMI patients, compliance with ESC 2015 NSTEMI Guidelines, and identify potential barriers to optimal management of this common clinical presentation associated with significant morbidity and mortality.

Alcohol consumption and telomere length: Mendelian randomization clarifies alcohol's effects. Mol Psychiatry 2022; 27:4001-4008.

Abstract
Alcohol's impact on telomere length, a proposed marker of biological aging, is unclear. We performed the largest observational study to date (in n = 245,354 UK Biobank participants) and compared findings with Mendelian randomization (MR) estimates. Two-sample MR used data from 472,174 participants in a recent genome-wide association study (GWAS) of telomere length. Genetic variants were selected on the basis of associations with alcohol consumption (n = 941,280) and alcohol use disorder (AUD) (n = 57,564 cases). Non-linear MR employed UK Biobank individual data. MR analyses suggested a causal relationship between alcohol traits, more strongly for AUD, and telomere length. Higher genetically-predicted AUD (inverse variance-weighted (IVW) β = -0.06, 95% confidence interval (CI): -0.10 to -0.02, p = 0.001) was associated with shorter telomere length. There was a weaker association with genetically-predicted alcoholic drinks weekly (IVW β = -0.07, CI: -0.14 to -0.01, p = 0.03). Results were consistent across methods and independent from smoking. Non-linear analyses indicated a potential threshold relationship between alcohol and telomere length. Our findings indicate that alcohol consumption may shorten telomere length. There are implications for age-related diseases.

Abstract
PURPOSE Four-corner fusion (4CF) is a surgical option for refractory scapholunate advanced collapse and scaphoid nonunion advanced collapse wrist arthritis. Preoperative range of motion (ROM) predicts outcomes in many orthopedic procedures. This study investigates ROM in a cohort of 4CF patients to examine the relationship between preoperative and postoperative motion and identifies different clinical patterns. METHODS We performed a retrospective review of 4CF patients. Patients with a history of inflammatory arthritis and radiographic characteristics of inflammation were excluded. Demographics, prior wrist surgery history, and ROM data were collected at preoperative and postoperative intervals after cast removal at 8 weeks, 3 months, and 8 months. Regression analysis compared the motion before and after 4CF. Subsequent cluster analysis to reduce confounding compared postoperative motion differences in the top 20% to the bottom 20% of patients by preoperative motion. RESULTS We included 148 patients; 27 had prior surgery on the ipsilateral wrist. Preoperative arc averaged 86° ± 28° (flexion 46° ± 17°, extension 40° ± 15°); 8-week arc 43° ± 19° (flexion 19° ± 12°, extension 24° ± 12°); 3-month arc 62° ± 17° (flexion 30° ± 12°, extension 32° ± 11°); and 8-month arc 74° ± 17° (flexion 36° ± 11°, extension 37° ± 12°). Preoperative and final arcs were (r = 0.39). Clustering by the preoperative arc, the top 20% (mean 124° ± 15°) achieved a mean final arc of 81° ± 16°, while the bottom 20% (mean 47° ± 16°) achieved a mean final arc of 65° ± 19°. Intercluster differences were statistically significant. The bottom 20% gained motion postoperatively. Most patients in the middle 60% did not differ significantly in postoperative motion. CONCLUSIONS Although wrist motion following 4CF correlates positively with preoperative motion, most patients do not differ significantly in postoperative motion. Patients with substantial preoperative motion deficits gain motion after 4CF. This information is important when counseling patients, determining the timing of surgical intervention, and managing expectations related to motion outcomes.

Clinical characteristics with inflammation profiling of long COVID and association with 1-year recovery following hospitalisation in the UK: a prospective observational study. THE LANCET. RESPIRATORY MEDICINE 2022; 10:761-775. [PMID: 35472304 PMCID: PMC9034855 DOI: 10.1016/s2213-2600(22)00127-8] [Citation(s) in RCA: 144] [Impact Index Per Article: 72.0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 01/04/2022] [Revised: 03/23/2022] [Accepted: 03/31/2022] [Indexed: 11/25/2022]
Abstract
BACKGROUND No effective pharmacological or non-pharmacological interventions exist for patients with long COVID. We aimed to describe recovery 1 year after hospital discharge for COVID-19, identify factors associated with patient-perceived recovery, and identify potential therapeutic targets by describing the underlying inflammatory profiles of the previously described recovery clusters at 5 months after hospital discharge. METHODS The Post-hospitalisation COVID-19 study (PHOSP-COVID) is a prospective, longitudinal cohort study recruiting adults (aged ≥18 years) discharged from hospital with COVID-19 across the UK. Recovery was assessed using patient-reported outcome measures, physical performance, and organ function at 5 months and 1 year after hospital discharge, and stratified by both patient-perceived recovery and recovery cluster. Hierarchical logistic regression modelling was performed for patient-perceived recovery at 1 year. Cluster analysis was done using the clustering large applications k-medoids approach using clinical outcomes at 5 months. Inflammatory protein profiling was analysed from plasma at the 5-month visit. This study is registered on the ISRCTN Registry, ISRCTN10980107, and recruitment is ongoing. FINDINGS 2320 participants discharged from hospital between March 7, 2020, and April 18, 2021, were assessed at 5 months after discharge and 807 (32·7%) participants completed both the 5-month and 1-year visits. 279 (35·6%) of these 807 patients were women and 505 (64·4%) were men, with a mean age of 58·7 (SD 12·5) years, and 224 (27·8%) had received invasive mechanical ventilation (WHO class 7-9). The proportion of patients reporting full recovery was unchanged between 5 months (501 [25·5%] of 1965) and 1 year (232 [28·9%] of 804). Factors associated with being less likely to report full recovery at 1 year were female sex (odds ratio 0·68 [95% CI 0·46-0·99]), obesity (0·50 [0·34-0·74]) and invasive mechanical ventilation (0·42 [0·23-0·76]). Cluster analysis (n=1636) corroborated the previously reported four clusters: very severe, severe, moderate with cognitive impairment, and mild, relating to the severity of physical health, mental health, and cognitive impairment at 5 months. We found increased inflammatory mediators of tissue damage and repair in both the very severe and the moderate with cognitive impairment clusters compared with the mild cluster, including IL-6 concentration, which was increased in both comparisons (n=626 participants). We found a substantial deficit in median EQ-5D-5L utility index from before COVID-19 (retrospective assessment; 0·88 [IQR 0·74-1·00]), at 5 months (0·74 [0·64-0·88]) to 1 year (0·75 [0·62-0·88]), with minimal improvements across all outcome measures at 1 year after discharge in the whole cohort and within each of the four clusters. INTERPRETATION The sequelae of a hospital admission with COVID-19 were substantial 1 year after discharge across a range of health domains, with the minority in our cohort feeling fully recovered. Patient-perceived health-related quality of life was reduced at 1 year compared with before hospital admission. Systematic inflammation and obesity are potential treatable traits that warrant further investigation in clinical trials.

Abstract
BackgroundJuvenile idiopathic arthritis (JIA) encompasses a group of heterogeneous rheumatic diseases of childhood onset. JIA can result in long term disability and remission is the main goal of treatment. However refractory disease can occur, which is defined as the absence of response to a standard disease therapy. A genetic basis for refractory disease has yet to be explored, where deleterious rare variants can complicate diagnosis or treatment outcome.ObjectivesTo investigate, through genetic analysis, whether children with JIA that is refractory carry rare genetic risk factors in genes linked to monogenic diseases.MethodsWhole exome sequencing of 99 children with JIA was performed with the Agilent SureSelect Human All ExonV6 kit. All quality control, variant filtering and annotation was performed in Varseq (version 2.2.1). Variants with a read depth <30 and genotype quality <80 were removed. Rarity and pathogenicity filters were then applied to remove variants with an allele frequency >1% (based on ExAC, gnomAD, gnomAD exome, NHLBI and 1KGp phase 3), classified as benign or likely benign on ClinVar, with a CADD PHRED score <15 and a REVEL score >0.7. Variants were annotated if they appeared in a gene from the primary immunodeficiency PanelApp (Martin et al., 2019), in a gene associated with an arthritis phenotype or in a gene that appeared on a paediatric monogenic gene list. The variants were then classified using ACMG guidelines (Richards et al., 2015) and benign, or likely benign, classified variants were removed.ResultsA total of 628 variants were identified and we found that 20 out of the 99 children screened were heterozygous for at least one recognised variant in a gene linked to a monogenic disease. Five of these children carried more than one recognised variant linked to monogenic genes. Here we provide a number of illustrative examples: three genes, ADAR, ATP7B and MVK, were prioritised based on prior evidence of associated disease. The variant p.Pro193Ala (gnomAD allele frequency (GAD) 2.2x10-3) of ADAR has previously been deemed pathogenic in a homozygous or compound heterozygous state for Aicardi-Goutières syndrome. Adenosine deaminases (ADARs) catalyse the hydrolytic deamination of adenosine to inosine in dsRNA and is suggested to act as a suppressor of type 1 interferon-stimulated genes. Within ATP7B, two distinct variants were detected; p.Gln1142His (GAD 1.6x10-5) and p.Ile1148Thr (GAD 4.0x10-5) have previously been reported as pathogenic, in combination with a third variant, for Wilson’s disease and were carried by one individual in this cohort. ATP7B encodes copper-transporting ATPase 2, which supplies copper to ceruloplasmin. Variant p.Val377Ile (GAD 1.6x10-3) of MVK was detected in eight individuals in this cohort, interestingly five of these individuals also carried at least one HLA-DRB1 stop-gained variant. This MVK mutation has been confirmed as pathogenic in a homozygous or compound heterozygous state for mevalonate kinase deficiency. MVK converts mevalonic acid into mevalonate-5-phosphate in the cholesterol synthesis pathway. Additionally, two stop-gained loss of function HLA-DRB1 variants, p.Tyr107Ter and p.Gln125Ter, were detected in five and 20 individuals, respectively, in this cohort. HLA-DRB1 is a recognised susceptibility locus for JIA.ConclusionScreening of a cohort of 99 children with JIA that have refractory disease has revealed that individuals carry deleterious variants in genes linked to monogenic forms of disease. These results highlight that the genetic basis for refractory disease needs to be further investigated. Carrying additional genetic risk factors to disease may complicate disease outcome and genetic screening of children with refractory JIA may improve treatment outcome in the future.AcknowledgementsI would like to acknowledge the CLUSTER consortium.Disclosure of InterestsNone declared

Abstract
Background Our objective was to assess new chronic hypertension 6 to 12 months postpartum for those with hypertensive disorder of pregnancy (HDP) compared with normotensive participants. Methods and Results We performed a prospective cohort study of participants with singleton gestations and no known preexisting medical conditions who were diagnosed with HDP compared with normotensive women with no pregnancy complications (non-HDP). Participants underwent cardiovascular risk assessment 6 to 12 months after delivery. Primary outcome was onset of new chronic hypertension at 6 to 12 months postpartum. We also examined lipid values, metabolic syndrome, prediabetes, diabetes, and 30-year cardiovascular disease (CVD) risk. Multivariable logistic regression was performed to assess the association between HDP and odds of a postpartum diagnosis of chronic hypertension while adjusting for parity, body mass index, insurance, and family history of CVD. There were 58 participants in the HDP group and 51 participants in the non-HDP group. Baseline characteristics between groups were not statistically different. Participants in the HDP group had 4-fold adjusted odds of developing a new diagnosis of chronic hypertension 6 to 12 months after delivery, compared with those in the non-HDP group (adjusted odds ratio, 4.60 [95% CI, 1.65-12.81]), when adjusting for body mass index, parity, family history of CVD, and insurance. Of the HDP group, 58.6% (n=34) developed new chronic hypertension. Participants in the HDP group had increased estimated 30-year CVD risk and were more likely to have metabolic syndrome, a higher fasting blood glucose, and higher low-density lipoprotein cholesterol. Conclusions Participants without known underlying medical conditions who develop HDP have 4-fold increased odds of new diagnosis of chronic hypertension by 6 to 12 months postpartum as well as increased 30-year CVD risk scores. Implementation of multidisciplinary care models focused on CVD screening, patient education, and lifestyle interventions during the first year postpartum may serve as an effective primary prevention strategy for the development of CVD.

Abstract
The Better Understanding the Metamorphosis of Pregnancy (BUMP) study is a longitudinal feasibility study aimed to gain a deeper understanding of the pre-pregnancy and pregnancy symptom experience using digital tools. The present paper describes the protocol for the BUMP study. Over 1000 participants are being recruited through a patient provider-platform and through other channels in the United States (US). Participants in a preconception cohort (BUMP-C) are followed for 6 months, or until conception, while participants in a pregnancy cohort (BUMP) are followed into their fourth trimester. Participants are provided with a smart ring, a smartwatch (BUMP only), and a smart scale (BUMP only) alongside cohort-specific study apps. Participant centric engagement strategies are used that aim to co-design the digital approach with participants while providing knowledge and support. The BUMP study is intended to lay the foundational work for a larger study to determine whether participant co-designed digital tools can be used to detect, track and return multimodal symptoms during the perinatal window to inform individual level symptom trajectories.

Dead-reckoning elucidates fine-scale habitat use by European badgers Meles meles. ANIMAL BIOTELEMETRY 2022; 10:10. [PMID: 37521810 PMCID: PMC8908954 DOI: 10.1186/s40317-022-00282-2] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Subscribe] [Scholar Register] [Received: 11/11/2021] [Accepted: 02/23/2022] [Indexed: 05/03/2023]
Abstract
Background Recent developments in both hardware and software of animal-borne data loggers now enable large amounts of data to be collected on both animal movement and behaviour. In particular, the combined use of tri-axial accelerometers, tri-axial magnetometers and GPS loggers enables animal tracks to be elucidated using a procedure of 'dead-reckoning'. Although this approach was first suggested 30 years ago by Wilson et al. (1991), surprisingly few measurements have been made in free-ranging terrestrial animals. The current study examines movements, interactions with habitat features, and home-ranges calculated from just GPS data and also from dead-reckoned data in a model terrestrial mammal, the European badger (Meles meles). Methods Research was undertaken in farmland in Northern Ireland. Two badgers (one male, one female) were live-trapped and fitted with a GPS logger, a tri-axial accelerometer, and a tri-axial magnetometer. Thereafter, the badgers' movement paths over 2 weeks were elucidated using just GPS data and GPS-enabled dead-reckoned data, respectively. Results Badgers travelled further using data from dead-reckoned calculations than using the data from only GPS data. Whilst once-hourly GPS data could only be represented by straight-line movements between sequential points, the sub-second resolution dead-reckoned tracks were more tortuous. Although there were no differences in Minimum Convex Polygon determinations between GPS- and dead-reckoned data, Kernel Utilisation Distribution determinations of home-range size were larger using the former method. This was because dead-reckoned data more accurately described the particular parts of landscape constituting most-visited core areas, effectively narrowing the calculation of habitat use. Finally, the dead-reckoned data showed badgers spent more time near to field margins and hedges than simple GPS data would suggest. Conclusion Significant differences emerge when analyses of habitat use and movements are compared between calculations made using just GPS data or GPS-enabled dead-reckoned data. In particular, use of dead-reckoned data showed that animals moved 2.2 times farther, had better-defined use of the habitat (revealing clear core areas), and made more use of certain habitats (field margins, hedges). Use of dead-reckoning to provide detailed accounts of animal movement and highlight the minutiae of interactions with the environment should be considered an important technique in the ecologist's toolkit.

SARS-CoV-2, Lung Protective Ventilation, Low Middle Income Countries, and Pediatric Intensivists as Cross Disciplinary Knowledge Translation and Implementation Science Specialists.

Abstract
Purpose We hypothesized that despite the low incidence of severe SARS-CoV-2 infections in children in Guyana, due to their specific skillset in lung protective ventilation, our Pediatric Intensivists were uniquely positioned to address significant training and readiness gaps in our colleagues attending a surging critically ill Adult COVID-19 patient population. Methods & Materials In Guyana, there are few clinicians trained in Critical-Care Medicine (CCM). The high incidence of ventilator dependence in seriously ill SARS-CoV2 patients, combined with a dearth of CCM practitioners competent in complex mechanical ventilation management left Guyana ill prepared to manage these patients. This knowledge deficit was further exacerbated in that many clinicians at our National Infectious Diseases Hospital were co-opted into CCM roles from other specialties with little to no CCM training. We have a very small core of Pediatric Surgical Critical Care Medicine staff that was formally trained in PCCM outside of Guyana. This core was instrumental in establishing a unique and formal Pediatric Critical-Care Medicine Micro-Modular Fellowship (PCCM-MMF) program that allowed the creation of Guyana's only Pediatric ICU. A significant number of that core are also involved in Guyana‘s National COVID Task Force. Given that all graduates of our PCCM-MMF program are extensively trained in Lung Protective Ventilation, it was very appropriate to utilize them to augment Adult critical care capacity. Thirty physicians with primarily adult practices and little to no previous knowledge of ventilator management were enrolled in a multi-modal triphasic mechanical ventilation short course facilitated by PCCM staff. Results We were able to rapidly enable two cohorts of 15 Adult clinicians to competently address critical knowledge deficits and staffing shortfalls. We improved morbidity and mortality amongst our mechanically ventilated adult COVID-19 patients, as well as relieved significant multifactorial caregiver strain. Conclusion Our successful utilization of PCCM staff as Mechanical Ventilation didactic and clinical educators for an Adult patient population carries implications for cross disciplinary Knowledge Translation and Implementation Science in a wide variety of practice milieus. We are actively pursuing research opportunities to further experiment with other skill sets incorporated in our PCCM Micro-Modular Fellowship and welcome potential collaborators.

Abstract
Medication‐related osteonecrosis of the jaws (MRONJ) is a painful debilitating condition which is considered rare in the medical literature available to prescribers. Dentists, however, are likely to trigger this condition through extractions and implants. Anecdotally MRONJ appears more common than first thought. This paper presents 13 cases of MRONJ diagnosed and treated by a single oral and maxillofacial surgeon based in Cairns, Far North Queensland, in a 2‐year period. The management of these cases is presented. The two cases where MRONJ resulted in the loss of dental implants are highlighted. © 2022 Australian Dental Association

ARMC5-associated Bilateral Macronodular Adrenocortical Hyperplasia: A Novel Germline Variant Associated with Concomitant Papillary Thyroid Carcinoma and Meningioma. Am J Clin Pathol 2021.

Abstract
Abstract
Introduction/Objective
Germline mutations in the tumor suppressor gene Armadillo-containing repeat protein 5 gene (ARMC5) have been very recently recognized as a cause for a familial form of bilateral macronodular adrenocortical hyperplasia (BMAH), itself a rare cause of Cushing syndrome. In patients with ARMC5 mutations, scattered case reports have also shown an association with meningiomas and cancers of the pancreas, breast, colon, and thyroid.
Methods/Case Report
We present the case of BMAH, arising in a 61-year-old female with a history of metastatic papillary thyroid carcinoma and meningioma. The patient presented with bilateral but asymmetric adrenal enlargement (right greater than left) and Cushing syndrome. Given history of thyroid cancer and meningioma, genetics referral was ordered. Counseling revealed a pedigree without a strongly evident familial pattern of hereditary endocrine neoplasia characteristic of any of the more common inherited dispositions to endocrine neoplasia. Additionally, a targeted capture-based NGS germline genetic sequencing study for variants in 12 genes associated with associated with hereditary thyroid cancer was performed and negative. However, based on recent scholarship regarding ARMC5, follow-up germline NGS and Sanger sequencing studies encompassing the entire coding sequences of ARMC5 were ordered. These identified a germline, heterozygous, novel (not in ClinVar) but likely pathogenic variant in (c.802C>T, p.Arg268*), providing a likely explanation for the patient’s BMAH. In attempt to control the patient’s Cushing symptoms, right-sided adrenalectomy was performed, revealing a 220g adrenal gland with marked multinodular hyperplasia with solid, nested, and tubular architecture.
Results (if a Case Study enter NA)
NA
Conclusion
While case reports exist describing an association between other ARMC5 mutations and BMAH with concomitant meningiomas and/or malignancies, greater study is needed in order to better characterize the phenotypic spectrum of this disease. Our experience with this case not only reports a novel, apparently pathogenic mutation, but it documents its association with BMAH and, additionally, papillary thyroid carcinoma and meningioma.
