Management of Neuroendocrine Breast Carcinoma (NEBC): Review of Literature. Oncol Rev 2024; 18:12114. [PMID: 38404967 PMCID: PMC10884130 DOI: 10.3389/or.2024.12114] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/25/2023] [Accepted: 01/15/2024] [Indexed: 02/27/2024] Open
Abstract
Extra pulmonary high-grade poorly differentiated neuroendocrine carcinomas (EP-NECs) are rare tumors that usually arise in the gastrointestinal and genitourinary tracts. Primary neuroendocrine carcinoma of the breast (NEBC) is extremely rare, representing less than 0.1% of all breast cancers and less than 1% of neuroendocrine neoplasms. Consequently, they can be misdiagnosed as other types of breast cancer, however, proper immunohistochemical (IHC) studies can assist with making the correct diagnosis. Management of NEBC can be challenging given the paucity of evidence-based literature and should not routinely follow the therapeutic guidelines of other breast cancers. In this article, we review the current literature regarding the management of NEBC.

Factors influencing final year radiography students' intention to pursue postgraduate education in medical imaging. Radiography (Lond) 2024; 30:388-393. [PMID: 38159357 DOI: 10.1016/j.radi.2023.12.006] [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: 04/12/2023] [Revised: 10/27/2023] [Accepted: 12/13/2023] [Indexed: 01/03/2024]
Abstract
INTRODUCTION Postgraduate education in medical imaging is an important platform that can support in preparing radiographers for the role extension and advancement in radiography. Thus, this study aims to identify the factors influencing final year radiography students' intention to pursue postgraduate education in medical imaging. METHODS An online cross-sectional survey was conducted among final year students in medical imaging programs from six institutions in Malaysia. Purposive convenience sampling has been employed. Data collection was related to students' interest in postgraduate study and possible factors that may affect students' intention to pursue postgraduate education after study degree completion. The questionnaire was a combination of a Likert Scale and open-ended question. RESULTS A total of 148 (female, n = 132 and male, n = 16) responses were included in the analysis. Among the participants, n = 93 (62.8 %) of students intended to pursue study. The highest choice of study was mixed mode (41.9 %) and cardiac imaging was the field of choice by the students (22.3 %). Five factors have been found to significantly correlate with the students' intention to pursue postgraduate study in medical imaging which were student attributes, being an academician, remuneration, finance, and social influences (p < 0.05). Two factors that did not significantly correlate with the students' intention were being an expert in the field and Covid-19 (p > 0.05). CONCLUSION Five out of seven factors tested were found to significantly influence students' decision to pursue postgraduate education in medical imaging. Effective strategies based on the influencing factors should be strategized to encourage more students to pursue postgraduate education in medical imaging. IMPLICATIONS FOR PRACTICE Implementation of effective strategies based on the influencing factors will improve access to education among radiography students, ultimately enhancing future radiographers' capability and competency.

Distribution of natural radionuclides in NORM samples from North Abu Rusheid area, Egypt. JOURNAL OF ENVIRONMENTAL RADIOACTIVITY 2023; 266-267:107240. [PMID: 37418811 DOI: 10.1016/j.jenvrad.2023.107240] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 02/10/2023] [Revised: 06/08/2023] [Accepted: 06/30/2023] [Indexed: 07/09/2023]
Abstract
The North Abu Rusheid area in Egypt is a well-known high background natural radiation area (HBNRA) due to the existence of naturally occurring radioactive materials (NORMs) in mylonitic rocks. In this study, 27 rock samples were selected for dose estimation studies. 238U and 232Th were measured using inductively coupled plasma mass spectrometry (ICP-MS) and 40K was measured using sodium iodide (thallium) gamma-ray spectroscopy. The ranges of activity concentrations (Bq/kg) of 238U, 232Th and 40K in the samples varied from 270 ± 2 to 2120 ± 29, 350 ± 2 to 1840 ± 27 and 20 ± 2 to 1390 ± 35 with mean values of 980 ± 349, 770 ± 351, and 640 ± 402 Bq/kg, respectively. The radiological hazard parameters were estimated from activity concentrations of 238U, 232Th and 40K and compared to United Nations Scientific Committee on the Effects of Atomic Radiation (UNSCEAR) values. The present study revealed that the hazard parameters were several times higher than the worldwide averages. The U/Th concentration ratio ranged from 0.7 to 3 and could be attributed to the presence of kasolite, uranothorite, zircon, and columbite in mylonitic rocks. From the radiological protection viewpoint, it is necessary to monitor natural radionuclides in these rocks prior to their use in residential and commercial construction materials.

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.

Abstract
Measurements of the associated production of a W boson and a charm ( c ) quark in proton-proton collisions at a centre-of-mass energy of 8 TeV are reported. The analysis uses a data sample corresponding to a total integrated luminosity of 19.7 fb - 1 collected by the CMS detector at the LHC. The W bosons are identified through their leptonic decays to an electron or a muon, and a neutrino. Charm quark jets are selected using distinctive signatures of charm hadron decays. The product of the cross section and branching fraction σ ( pp → W + c + X ) B ( W → ℓ ν ) , where ℓ = e or μ , and the cross section ratio σ ( pp → W + + c ¯ + X ) / σ ( pp → W - + c + X ) are measured in a fiducial volume and differentially as functions of the pseudorapidity and of the transverse momentum of the lepton from the W boson decay. The results are compared with theoretical predictions. The impact of these measurements on the determination of the strange quark distribution is assessed.

Abstract
The use of flying robots (drones) is increasing rapidly, but their utility is limited by high power demand, low specific energy storage and poor gust tolerance. By contrast, birds demonstrate long endurance, harvesting atmospheric energy in environments ranging from cluttered cityscapes to open landscapes, coasts and oceans. Here, we identify new opportunities for flying robots, drawing upon the soaring flight of birds. We evaluate mechanical energy transfer in soaring from first principles and review soaring strategies encompassing the use of updrafts (thermal or orographic) and wind gradients (spatial or temporal). We examine the extent to which state-of-the-art flying robots currently use each strategy and identify several untapped opportunities including slope soaring over built environments, thermal soaring over oceans and opportunistic gust soaring. In principle, the energetic benefits of soaring are accessible to flying robots of all kinds, given atmospherically aware sensor systems, guidance strategies and gust tolerance. Hence, while there is clear scope for specialist robots that soar like albatrosses, or which use persistent thermals like vultures, the greatest untapped potential may lie in non-specialist vehicles that make flexible use of atmospheric energy through path planning and flight control, as demonstrated by generalist flyers such as gulls, kites and crows.

Abstract
Abstract
Background
Older adults attend the Emergency Department (ED) frequently. Over 40% are directly discharged from the ED. The risk of adverse outcomes is high following discharge including unplanned ED return, institutionalisation, and mortality. The purpose of this study was to highlight factors that predict these adverse outcomes.
Methods
A secondary analysis was completed of SOAED (a prospective cohort study examining screening instruments to predict adverse outcomes for undifferentiated older adults attending the ED) and OPTIMEND (randomised control trial examining the effectiveness of an intervention by a team of Health and Social Care Professionals along with usual care and compared this to standard ED care alone). Inclusion criteria were adults aged 65 years and over presenting to ED at a University Teaching Hospital with medical complaints and a Manchester Triage System category 2–5.
Results
Three-hundred and nine patients were discharged directly from ED (mean age 80 years; 58% female). 96 patients re-attended ED within 6 months. 66 patients were re-hospitalised within 6 months. 16 patients died within six months of discharge. 63% of the discharged patients screened positive for frailty measured by PRISMA-7 (3 or more). Relative risk ratio analysis confirmed that the risk of revisiting a hospital was 1.241 times for patients that scored frail compared to those who scored not frail. The risk of mortality was 1.075 times for patients that scored frail compared to those who scored not frail. The risk of being admitted to a nursing home was 1.146 times for patients that scored frail compared to those who scored not frail.
Conclusion
Older people have a high ED re-attendance rate of 31% after an index visit. Frailty (scored on PRISMA-7) is a significant predictor of adverse outcomes. Focused screening and intervention for frail patients who attend the ED should be a priority.

Abstract
Squamous cell cancer of the head and neck (HNSCC) is the sixth most common cancer and is associated with significant morbidity and mortality. The tumor microenvironment for HNSCC is a complex interplay of immune cells, stromal cells, and cytokines amongst others. Immunotherapy acts as an effective antineoplastic agent by influencing this complex environment and includes immune checkpoint inhibitors (ICI). ICI have been approved in the frontline setting for recurrent and metastatic (R/M) HNSCC as well as platinum-refractory (second line) R/M HNSCC. However, recent clinical studies highlight that the response to immunotherapy varies, and different ICI, as well as different combination strategies play a crucial role in augmenting the efficacy of immunotherapy. An in-depth analysis and focused study of the immune contexture in patients with HNSCC receiving ICI remains critical. Many novel immunotherapies including CAR-T cell therapy, oncolytic virus therapy, and vaccines are underway. Ongoing trials are testing ICI in the neoadjuvant and adjuvant settings. Furthermore, identifying better biomarkers to target population that benefits from immunotherapy is of paramount importance. Pioneering the optimal combination regimen utilizing new novel immunotherapy has recently become a paradigm shift in the HNSCC treatment landscape. Herein, we summarize the clinical development with all ongoing clinical trials of immunotherapy in HNSCC.

Effects of Group-I Elements on Output Voltage Generation of ZnO Nanowires Based Nanogenerator; Degradation of Screening Effects by Oxidation of Nanowires. MICROMACHINES 2022; 13:1450.

Abstract
Here, we report the successful incorporation of group I elements (K, Na, Li) to ZnO nanowires. Three distinct (2, 4, and 6 wt.%) doping concentrations of group I elements have been used to generate high piezoelectric voltage by employing a vertically integrated nanowire generator (VING) structure. X-ray photoelectron spectra (XPS) indicated the seepage of dopants in ZnO nanowires by substitution of Zn. Shallow acceptor levels (LiZn, NaZn, KZn) worked as electron trapping centers for intrinsically n-type ZnO nanowires. Free moving electrons caused a leakage current through the nanowires and depleted their piezoelectric potential. Reverse leakage current is a negative factor for piezoelectric nanogenerators. A reduction in reverse leakage current signifies the rise in output voltage. A gradual rise in output voltage has been witnessed which was in accordance with various doping concentrations. K-doped ZnO nanowires have generated voltages of 0.85 V, 1.48 V, and 1.95 V. For Na-doped ZnO nanowires, the voltages were 1.23 V, 1.73 V, and 2.34 V and the voltages yeilded for Li-doped ZnO nanowires were 1.87 V, 2.63 V, and 3.54 V, respectively. Maximum voltage range has been further enhanced by the surface enrichment (oxidized with O2 molecules) of ZnO nanowires. Technique has been opted to mitigate the screening effect during an external stress. After 5 h of oxidation in a sealed chamber at 100 ppm, maximum voltage peaks were pronounced to 2.48 V, 3.19 V, and 4.57 V for K, Na, and Li, respectively. A low-cost, high performance mechanical transducer is proposed for self-powered devices.

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.

Type of funding sources: None.
Background
Cancer and heart failure frequently co-exist, with cancer and chemotherapy exerting a number of pathological effects on the myocardium. Despite this, our understanding of the clinical impact of previous history of cancer in acute heart failure remains unclear. We therefore performed a retrospective cohort study to identify the echocardiographic characteristics in patients admitted with acute heart failure with and without a diagnosis of solid organ cancer.
Methods
Consecutive patients with signs and/or symptoms of acute heart failure admitted over a period of 33 weeks (7th January – 28th August 2020) were identified. Discharge summaries, electronic notes and shared care networks were manually searched to determine baseline demographics, admission bloods, comorbidities, cancer diagnoses, imaging and echocardiography. Univariate and multivariate Cox regression analysis was performed to identify clinical and biochemical predictors of mortality.
Results
In total, 478 patients were admitted with acute heart failure over the study period (mean age 80 ± 11 years, 53.6% were male and mean NT pro-BNP was 9106). 386 had echocardiography available for review. Of these, 64 (16.6%) had a past or current history of solid organ cancer.
Patients with a past or current history of solid organ cancer had a significantly higher ejection fraction (48% (±9%) vs 44% (±11%), p = 0.003), higher incidence of heart failure with preserved ejection fraction (57.8% vs 33.5%, p < 0.001) and lower incidence of right ventricular impairment (defined using both visual inspection and TAPSE measurements) (25.0% vs 47.8%, p < 0.001).
There were no significant differences in any valvular pathologies between groups (overall prevalence 71.9% vs 71.7%, p = 0.982) No difference was observed between the rate of prior myocardial infarction (28.1% vs 26.0%, p = 0.727) or lung disease (34.4% vs 37.0%, p = 0.692).
Overall, mortality at six months follow up was significantly higher in the group with a current or previous cancer diagnosis (43.4% vs 32.0%, p = 0.046) compared to the group without.
Conclusion
Patients admitted with acute heart failure and a past or current history of cancer have a significantly higher ejection fraction and lower prevalence of right ventricular impairment. Despite the higher ejection fraction their prognosis is worse. Further work is needed to determine potential mechanisms for this, as well as its clinical implications. Abstract Figure.

233 BISPHOSPHONATES: ANOTHER COMPLEX DRUG TO PRESCRIBE. Age Ageing 2021. [DOI: 10.1093/ageing/afab219.233] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Indexed: 02/25/2023] Open
Abstract
Abstract
Background
Bisphosphonates provide effective treatment for osteoporosis. They accumulate a bone reservoir lasting for 3 years and beyond. The 2021 NICE guidelines recommend a medication review and a ‘drug holiday’ after 5 years of oral bisphosphonate therapy for low-fracture risk patients. Continuing treatment for high risk individuals is advised: age=/>75, previous hip or vertebral fracture, one or more fractures during treatment, recent DEXA scan with T score =/<−2.5, and/or current treatment with oral glucocorticoids. This retrospective audit aimed to assess compliance with NICE guidelines in a primary care setting.
Methods
Data were collected using the Health One online medical record system in an urban general practice. Inclusion criteria: all patients =/> 65 years old, prescribed oral bisphosphonate therapy for osteoporosis for >5 years. Exclusion criteria: deceased, did not attend clinic >1 year, patients on bisphosphonate treatment for conditions other than osteoporosis.
Results
137 patients with a history of bisphosphonate therapy were identified. 76 patients were on bisphosphonate treatment for greater than 5 years. Of the 76 patients, 33 were classified as low-fracture risk and appropriately commenced a drug holiday, while 22 correctly remained on bisphosphonates due to a high fracture risk. The remaining 21 patients inappropriately continued therapy without receiving a medication review, repeat DEXA or fracture-risk assessment.
Conclusion
One third of patients on bisphosphonates beyond 5 years were not assessed for a drug holiday. The aim of a bisphosphonate ‘drug holiday’ is to reduce poly-pharmacy and prevent rare but serious long-term adverse events (such as atypical fractures, osteonecrosis of the jaw, gastric cancer and atrial fibrillation). Factors which had an impact on inappropriate prescribing should be assessed. Incorporating computer-based prescribing alerts could support safe prescribing practices.

Abstract
Abstract
Background
Depression is the most common neuropsychiatric manifestation after stroke. It is associated with lower satisfaction and quality of life in stroke survivors and their families. Routine screening for mood disturbance is recommended in stroke patients {Royal College of Physicians, 2016; National Office of Clinical Audit (NOCA) 2019}. The psychological impact of a stroke can present challenges for assessment and diagnosis. We audited the assessment and diagnosis of post stroke depression in a teaching hospital.
Methods
PHQ-9 was prospectively administered to stroke patients (and also to the next of kin with patient consent) within 2 weeks of stroke and repeated at 4–6 weeks after stroke in November 2016. The Patient Health Questionnaire (PHQ—9) is a self-administered, validated screening tool for depression. Chart diagnosis or drug prescribing for depression was retrospectively assessed in the medical and nursing notes.
Results
15 of 34 admitted stroke patients were administered the paper based PHQ-9. 19 patients were excluded due to: severe cognitive impairment; aphasic; death or having been discharged.
No patient had depression diagnosed prior to admission to the hospital. One patient was diagnosed and prescribed an anti-depressant post stroke.
7 patients screened positive for depression on PHQ-9: mild depression n = 4 (27%); moderate n = 2 (13%); and severe depression n = 1 (6%). Repeat questionnaire at 4–6 weeks post stroke revealed an unchanged PHQ-9 score in n = 10 (67%); however n = 2 (11%) had deteriorated and n = 4 (22%) improved.
Conclusion
Depression was a common finding in 47% of patients post stroke and was under-recognized without a formal screening process incorporated in clinical practice. A nuanced screening process, accounting for common co-morbidities such as aphasia and cognitive impairment, was incorporated after this audit. Further guidance is being developed by the National Stroke Programme based on NOCA feedback.

Abstract
Abstract
Background
Mortality for Intracerebral haemorrhage (ICH) is 31% (Irish National Audit Stroke, 2019). An ICH care bundle focusing on acute anticoagulation reversal, blood pressure lowering, and a neurosurgical care pathway was associated with improved survival. Translating evidence-based medicine into clinical practice is challenging. The aim of this study was to determine feasibility and outcomes of implementation of a care bundle.
Methods
An ICH care bundle was developed using an iterative process involving expert stakeholder review of the evidence-based literature. A pre-and-post quasi-experimental research design was employed to evaluate this intervention. Baseline data were collected before implementation (January 2016-June 2018). Implementation took place in a staged manner in a single university teaching hospital with multiple ‘Plan Do Study Act cycles’ (June 2018 to January 2021). Data on compliance, process measures and outcomes were collected.
Results
Systolic blood pressure (first 24-hours) and anticoagulant reversal were significantly better controlled post-implementation (χ2 (1, N = 91) = 5.34, P = 0.02), (χ2 (1, N = 25) = 5.85, P = 0.016), respectively. DNAR orders were significantly lower in the post-implementation group (χ2 (1, N = 25) = 5.85, P = 0.029). However, ‘Do Not Actively Resuscitate’ status did not significantly differ when accounting for low GCS as a surrogate measure for poor prognosis (χ2 (1, N = 34) = 0.00, P = 0.966). Modified Rankin Scale on discharge did not differ significantly pre-and-post-implementation (z = −0.075, P = 0.94). A greater proportion of patients survived in the post-implementation group; however, this was not statistically significant (χ2 (1, N = 133) = 0.77, P = 0.38). Length of stay significantly increased post implementation.
Conclusion
An ICH care bundle was developed based on expert stakeholder feedback. The feasibility of implementing this bundle of care was demonstrated in a real-world clinical practice setting. A cluster-randomized trial or a large registry study is the next step to evaluate the overall impact of this care bundle on patient outcomes.

Abstract
Abstract
Background
Stroke is a leading cause of death and disability. Thrombolysis with intravenous (IV) alteplase is the mainstay management of ischaemic stroke. It has a narrow therapeutic window with a high potential for adverse outcomes such as intracranial haemorrhage. The efficacy of alteplase is time and dose dependent with weight-based dosing. National clinical guidelines recommend a dose of 0.9 mg/kg, up to a maximum of 90 mg. (Irish Heart Foundation Council for Stroke 2015). In most hospitals in Ireland however, patients are not weighed prior to thrombolysis. Time pressure and lack of available suitable equipment are factors.
Methods
This retrospective clinical audit evaluated the dosing of alteplase, estimated and actual weight for a convenience sample of stroke thrombolysis patients treated between 2016–2020 at an Irish University Teaching Hospital.
Results
107 patients were audited (62 males, 45 females). Actual and estimated weights were available in 92/107. Weight was not documented (n = 15) due to severe stroke/palliative management (n = 6) or omission (n = 9). 21% (19/92) received the correct dose of 0.9 mg/kg. A further 54% (50/92) received a dose within the range of 0.81–0.99 mg/kg (±10%). 25% received a dose outside this range (> ± 10%). 11% (10/92) were under-thrombolysed and 14% (13/92) over-thrombolysed. 17/92 patients had an intracranial haemorrhage. 35% (n = 6/17) of patients who had an intracranial haemorrhage received a higher dose of thrombolysis (>10%).
Conclusion
A quarter of patients received inappropriate dosing of alteplase that was outside the range of ±10% of 0.9 mg/kg. While stroke thrombolysis must be completed urgently, an accurate weight should be determined to avoid errors in dosing. A process evaluation of stroke thrombolysis would provide information on how best to incorporate an objective means of weight measurement without delaying treatment.

Abstract
Abstract
Background
Over 40% of older patients are discharged directly from the Emergency Department (ED) and this cohort is at increased risk of adverse outcomes.
The purpose of this study was to explore the factors that predict future adverse outcomes in this cohort to inform practice, resource planning and policy.
Methods
A secondary analysis of the OPTIMEND, a single-centre, randomized-controlled trial was completed. OPTIMEND examined the effectiveness of an intervention by a team of Health and Social Care Professionals along with usual care and compared this to standard ED care alone (Dec 2018-May 2019). The inclusion criteria were adults aged 65 years and over presenting to the ED at a University Teaching Hospital with medical complaints and a Manchester Triage System category 2–5.
Results
220 patients were included (median age 79 years; 62% female). Median length of stay in ED was 5.5 hrs. 70 patients re-attended the ED within 6 months with 43 re-hospitalised within 6 months. 9 patients died within six months of discharge.
Multivariant logistic regression was completed. Age was the only independent predictor of mortality within six months of discharge {Odds Ratio (OR) 1.15, p = 0.044}. Past hospitalisation (<6 months) was associated with a lower likelihood of ED re-attendance, and rehospitalization within six months of discharge (OR: 0.452 p = 0.022; OR:0.442, p = 0.046; respectively). Clinical Frailty Score was associated with a significantly higher likelihood of rehospitalization (OR:1.48, p = 0.031) but not with ED revisits (OR: 1.235, p = 0.165).
Conclusion
Older people have a high ED re-attendance rate of 33% after an index visit with 20% hospitalized subsequently. Frailty is a significant predictor of rehospitalisation. Rapid and targeted intervention for frail patients who reattend the ED should be a priority for the integrated care program to enhance admission avoidance.

Abstract
Background Severe acute respiratory coronavirus 2 (SARS-CoV-2) was first recorded in Ireland in February 2020. Several studies have explored the association between age and SARS-CoV-2, showing that there were poorer outcomes in older people. Our objective was to evaluate the impact of age on outcomes such as hospital length of stay, mortality, and re-hospitalisation. Methods We performed a single-centre, retrospective observational cohort study, using an electronic microbiology database of recorded index admissions of SARS-CoV-2 positive patients aged 65 years and older during SARS-CoV-2 wave one (March 1st to May 31st 2020). PCR testing of nasopharyngeal and/or sputum samples was used to confirm positivity. Our clinical outcomes measured included hospital length of stay, mortality and re-admission rate within 6 months. Results 153 patients 65 years and above were admitted. The male to female ratio was 1.3 with 90% admitted medically. 79 patients were aged between 65–79 years; 84 patients ≥80 years; and 12 patients ≥90 years. Mortality was 25%, 31% and 42%, respectively. Median length of stay remained 14 days for ages 65–89 rising to 17.5 days for those ≥90 years. Re-hospitalisation rates at 6 months were similar for ages 65–79 and 89–89 years at 42% and 40%, respectively. One patient (14%) over 90 years was re-hospitalised. Conclusion SARS-CoV-2 has disproportionately impacted on general medical services treating older hospitalised people. In our centre, mortality for patients ≥65 years was 28.1% which compared favourably with 35.6% internationally as outlined by Victor et al. (2020) based on Spanish data. Treatment of SARS-CoV-2 is not futile in older patients with 58% of nonagenarians and 69% of octogenarians surviving, however re-hospitalisation rates are high at 40%. A targeted approach to discharge support via integrated care may ameliorate this.

Abstract
Abstract
Introduction
A good handover is fundamental in providing continuity of care within a multidisciplinary team, allowing for safe and effective management of patients.
Method
Handovers between the neurosurgical high dependency unit and the ward team were prospectively evaluated as patients were stepped down over a 6-week period. The handover rate and consequences of poor handovers (missed investigations, referrals, or delayed discharges) were documented. After 6-weeks, handover proforma was introduced and the rates were recalculated.
Results
In the initial 6-week period, 36 patients were transferred, with only 2(5.6%) appropriately handed-over. Consequently, 9(26%) patients had delayed scans, 5(15%) missed referrals, and 24(71%) delayed discharges. In the 6-week period following the introduction of the proforma, a total of 28 patients were transferred, with 19(67.8%) documented handovers. Consequently, 1(3.5%) patient had a scan delay, 0 missed referrals and only 2(7%) patients had delayed discharges.
Conclusions
By raising awareness of handovers and introducing a proforma, we improved documented handovers by 62.3% whilst reducing the rate of missed investigations, referrals, and delayed discharges by over 90%. This project highlights how small, simple, and easy to enforce changes can lead to significant improvements in the quality of care provided to patients.

Observation of Forward Neutron Multiplicity Dependence of Dimuon Acoplanarity in Ultraperipheral Pb-Pb Collisions at sqrt[s_{NN}]=5.02 TeV. PHYSICAL REVIEW LETTERS 2021; 127:122001.

Abstract
The first measurement of the dependence of γγ→μ^{+}μ^{-} production on the multiplicity of neutrons emitted very close to the beam direction in ultraperipheral heavy ion collisions is reported. Data for lead-lead interactions at sqrt[s_{NN}]=5.02 TeV, with an integrated luminosity of approximately 1.5 nb^{-1}, are collected using the CMS detector at the LHC. The azimuthal correlations between the two muons in the invariant mass region 8<m_{μμ}<60 GeV are extracted for events including 0, 1, or at least 2 neutrons detected in the forward pseudorapidity range |η|>8.3. The back-to-back correlation structure from leading-order photon-photon scattering is found to be significantly broader for events with a larger number of emitted neutrons from each nucleus, corresponding to interactions with a smaller impact parameter. This observation provides a data-driven demonstration that the average transverse momentum of photons emitted from relativistic heavy ions has an impact parameter dependence. These results provide new constraints on models of photon-induced interactions in ultraperipheral collisions. They also provide a baseline to search for possible final-state effects on lepton pairs caused by traversing a quark-gluon plasma produced in hadronic heavy ion collisions.

Constraints on the Initial State of Pb-Pb Collisions via Measurements of Z-Boson Yields and Azimuthal Anisotropy at sqrt[s_{NN}]=5.02 TeV. PHYSICAL REVIEW LETTERS 2021; 127:102002. [PMID: 34533355 DOI: 10.1103/physrevlett.127.102002] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Subscribe] [Scholar Register] [Received: 03/25/2021] [Revised: 06/17/2021] [Accepted: 07/27/2021] [Indexed: 06/13/2023]
Abstract
The CMS experiment at the LHC has measured the differential cross sections of Z bosons decaying to pairs of leptons, as functions of transverse momentum and rapidity, in lead-lead collisions at a nucleon-nucleon center-of-mass energy of 5.02 TeV. The measured Z boson elliptic azimuthal anisotropy coefficient is compatible with zero, showing that Z bosons do not experience significant final-state interactions in the medium produced in the collision. Yields of Z bosons are compared to Glauber model predictions and are found to deviate from these expectations in peripheral collisions, indicating the presence of initial collision geometry and centrality selection effects. The precision of the measurement allows, for the first time, for a data-driven determination of the nucleon-nucleon integrated luminosity as a function of lead-lead centrality, thereby eliminating the need for its estimation based on a Glauber model.

Abstract
This study aimed to determine the role of global longitudinalstrain (GLS) in early diagnosis and detection of severity of coronaryartery disease (CAD) in non-diabetic patients with preservedleft ventricular ejection fraction (EF) without regionalwall motion abnormalities presented with chronic coronary syndrome,and to identify the role of territorial longitudinal strain(TLS) in detection of the affected coronary artery. We enrolled60 non-diabetic patients with suspected CAD who underwentresting echocardiography and speckle tracking imaging andsubsequently coronary angiography then results were correlatedtogether. Patients with family history of CAD (68.3%), hypertension(68.3%), smokers (43.3%), and dyslipidemia (81.6%). Allparticipants had normal left ventricular systolic function withmean EF of 64.02±6.15% and no regional wall motion abnormalitiesat rest. Patients were classified angiographically accordingto the number of the diseased vessels into: 3 vessels disease(43.3%), 1-2 vessels disease (35%), and normal coronaryangiography (21.7%) with GLS mean values of -13.69±1.94%,-15.4±1.74%, and -18.80±2.14%, respectively. There was a negativesignificant correlation between GLS values and the numberof diseased vessels (P=0.001). The values of TLS were significantlylower in myocardial regions supplied by stenotic arteries thanthose supplied by non-stenotic arteries. Mean TLS values forstenotic left anterior descending, left circumflex, and right coronaryarteries were -15.51±3.19, -13.06±2.90, -13.27±2.60 withP=0.011, 0.001, and 0.001, respectively. Speckle tracking derivedGLS is an effective non-invasive method in predicting presenceand severity of CAD and in locating the affected vessels basedon the distribution of segments affected in TLS.

Introduction – Black Afro-Caribbean hypertensives (BAHs) are exposed to a higher risk of heart failure (HF) than white hypertensives (WHs). Arterial afterload is higher in BAHs due to increased arterial stiffness and vascular volume; BAHs develop more often left ventricular (LV) hypertrophy, dilatation and systolic dysfunction than WHs. However, it is unclear whether other racial differences concur to the more pronounced LV remodelling in BAHs.
Methods – This cross-sectional study included hypertensive patients undergoing cardiovascular magnetic resonance for their clinical work-up (1.5T Aera Siemens-Healthcare). Clinical history and haemodynamic parameters were collected in all participants; a subset of patients had complete bio-humoral assay of the renin-angiotensin-aldosterone system (RAAs). Arm cuff pressure was measured during CMR. The CMR protocol included: i) Arterial afterload / LV arterial-coupling - pulse-wave-velocity (PWV), aortic (Ea) and LV elastance (Ees) by aorta anatomic and phase-contrast velocity-encoding imaging; ii) ventricular remodelling and function - LV and right ventricular (RV) volumes, mass, EF, LV peak-filling rate by short-axis cine images; global circumferential and longitudinal strains by cine feature tracking; iii) left atrial (LA) remodelling volumes and reservoir, conduit and booster functions by long-axis cine images; iv) tissue characterisation: T2 and pre/post-contrast T1 relaxation times, extracellular volume (ECV) by single mid-ventricular short-axis T1/T2-mapping.
Results – 34 BAHs and 35 WHs (52 ± 12 vs 45 ± 14 years, P < 0.05; 61% vs 65% males P = NS) were included in the study. Baseline features are summarised in the Table. LV systolic dysfunction was more prevalent in BAH than WHs (P = 0.038). Of note, BAHs tended to have greater LV volumes and significantly higher LV mass and septal thickness than WHs. In BAHs, but not in WHs, PWV was associated with increased septal thickness after correction for blood pressure and age (β-value: 0.447, P = 0.02). Normalised RV mass was greater in BHA than WHs; RV mass suits for the identification of racial or circulating factors predisposing to hypertrophy being largely unaffected by systemic afterload. In our study LV diastolic function and LA volumes were similar between BAHs and WHs, and none of the subjects had conditions associated with pre-capillary pulmonary hypertension. Hence, higher RV-mass in BAHs pinpoints a racial susceptibility to myocardial hypertrophy. Finally, in a subset of patients with RAAs assays (n = 43), the aldosterone/renin ratio was higher in BAHs than WHs (67.04 [IQR: 19.37-209.73] vs 13.77 [IQR: 7.47-40.43], P = 0.01).
Conclusion – BAHs have heightened LV remodelling than WHs because of racial predisposition to develop hypertrophy which also encompasses derangements in RAAs. Altogether, these findings may account for the greater risk for HF in BAHs than WHs.

Abstract
OBJECTIVE In response to the COVID-19 disaster, people have developed several psychological problems mainly stress, anxiety, and depression. These psychological problems have been seen in either normal people during the lockdown (who are waiting to get infected with COVID-19) and patients with COVID-19 (who are waiting for death). These psychological problems adversely affect immune functions causing more increase in the severity of COVID-19 associated disorders and death rates. Increasing the aerobic capacity is one of the effective methods that could be used to decrease stress, anxiety, and depression. Besides, increasing the aerobic capacity increases immune functions through autonomic regulation. Thus, this review was developed to summarize the effect of increasing the aerobic capacity on psycho-immune hormones commonly disturbed in people during the lockdown or patients with COVID-19 infection. MATERIALS AND METHODS This review was carried out by searching through Web of Science, Scopus, EBSCO, Medline databases. The search was conducted over clinical trials, literature reviews, and systematic reviews. The search included the possible effects of increasing the aerobic capacity on the functions of psycho-immune hormones. RESULTS This review found that increasing the aerobic capacity can decrease psychological problems commonly seen in people with COVID-19 and increase immune functions by modulating the levels of glucocorticoid, oxytocin, insulin, thyroid hormones. CONCLUSIONS This review demonstrated that increasing the aerobic capacity is a recommended treatment for decreasing the psychological problems commonly seen in people with COVID-19 because it has the potential for decreasing psychological problems and improving immune functions which would help counter COVID-19.

Abstract
Abstract
Introduction
A good handover is fundamental in providing continuity of care within a multidisciplinary team, allowing for safe and effective management of patients.
Method
Handovers between the neurosurgical high dependency unit and the ward team were prospectively evaluated as patients were stepped down over a 6-week period. The handover rate and consequences of poor handovers (missed investigations, referrals, or delayed discharges) were documented. After 6-weeks, handover proforma was introduced and the rates were recalculated.
Results
In the initial 6-week period, 36 patients were transferred, with only 2(5.6%) appropriately handed-over. Consequently, 9(26%) patients had delayed scans, 5(15%) missed referrals, and 24(71%) delayed discharges. In the 6-week period following the introduction of the proforma, a total of 28 patients were transferred, with 19(67.8%) documented handovers. Consequently, 1(3.5%) patient had a scan delay, 0 missed referrals and only 2(7%) patients had delayed discharges.
Conclusions
By raising awareness of handovers and introducing a proforma, we improved documented handovers by 62.3% whilst reducing the rate of missed investigations, referrals, and delayed discharges by over 90%. This project highlights how small, simple, and easy to enforce changes can lead to significant improvements in the quality of care provided to patients.

Abstract
Abstract
Introduction
Biliary atresia (BA) is the most common indication of liver transplantation in children. Several reports attributed BA to both prenatal and perinatal aetiologies, including a viral infection-induced auto-immune response that targets the bile ducts. Cytomegalovirus (CMV) remains the most common virus being linked to BA. This meta-analysis estimates to what extent CMV infection is detected in patients with BA.
Method
This study was conducted according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. The databases of MEDLINE/PubMed, WHO-Virtual Health Library (VHL), ScienceDirect, and Google Scholar were used for the systematic search. Random effects model was used to estimate the pooled prevalence estimate with the corresponding 95% confidence interval (CI) using StatsDirect statistical software.
Results
A total of 13 studies (covering 419 patients) that fulfilled the eligibility criteria were included in the meta-analysis. The pooled overall prevalence of CMV infection in patients with BA was 24.5% (95% CI 11.9 %– 33.9%).
Conclusions
The available data demonstrate that the detection of CMV infection is common in infants with BA. There is still a need for large studies with appropriate controls to examine various aspects of the association between CMV infection and BA.

Development and validation of HERWIG 7 tunes from CMS underlying-event measurements. THE EUROPEAN PHYSICAL JOURNAL. C, PARTICLES AND FIELDS 2021; 81:312.

Abstract
This paper presents new sets of parameters ("tunes") for the underlying-event model of the H E R W I G 7 event generator. These parameters control the description of multiple-parton interactions (MPI) and colour reconnection in H E R W I G 7 , and are obtained from a fit to minimum-bias data collected by the CMS experiment at s = 0.9 , 7, and 13 Te . The tunes are based on the NNPDF 3.1 next-to-next-to-leading-order parton distribution function (PDF) set for the parton shower, and either a leading-order or next-to-next-to-leading-order PDF set for the simulation of MPI and the beam remnants. Predictions utilizing the tunes are produced for event shape observables in electron-positron collisions, and for minimum-bias, inclusive jet, top quark pair, and Z and W boson events in proton-proton collisions, and are compared with data. Each of the new tunes describes the data at a reasonable level, and the tunes using a leading-order PDF for the simulation of MPI provide the best description of the data.

Abstract
The production of Z boson pairs in proton-proton ( p p ) collisions, p p → ( Z / γ ∗ ) ( Z / γ ∗ ) → 2 ℓ 2 ℓ ' , where ℓ , ℓ ' = e or μ , is studied at a center-of-mass energy of 13TeV with the CMS detector at the CERN LHC. The data sample corresponds to an integrated luminosity of 137fb - 1 , collected during 2016-2018. The Z Z production cross section,σ tot ( p p → Z Z ) = 17.4 ± 0.3 (stat) ± 0.5 (syst) ± 0.4 (theo) ± 0.3 (lumi) pb , measured for events with two pairs of opposite-sign, same-flavor leptons produced in the mass region 60 < m ℓ + ℓ - < 120 GeV is consistent with standard model predictions. Differential cross sections are also measured and agree with theoretical predictions. The invariant mass distribution of the four-lepton system is used to set limits on anomalous Z Z Z and Z Z γ couplings.

Search for dark matter produced in association with a leptonically decaying Z boson in proton-proton collisions at s = 13 Te . THE EUROPEAN PHYSICAL JOURNAL. C, PARTICLES AND FIELDS 2021; 81:13.

Abstract
A search for dark matter particles is performed using events with a Z boson candidate and large missing transverse momentum. The analysis is based on proton-proton collision data at a center-of-mass energy of 13Te , collected by the CMS experiment at the LHC in 2016-2018, corresponding to an integrated luminosity of 137fb - 1 . The search uses the decay channels Z → e e and Z → μ μ . No significant excess of events is observed over the background expected from the standard model. Limits are set on dark matter particle production in the context of simplified models with vector, axial-vector, scalar, and pseudoscalar mediators, as well as on a two-Higgs-doublet model with an additional pseudoscalar mediator. In addition, limits are provided for spin-dependent and spin-independent scattering cross sections and are compared to those from direct-detection experiments. The results are also interpreted in the context of models of invisible Higgs boson decays, unparticles, and large extra dimensions.

Search for dark matter produced in association with a leptonically decaying Z boson in proton-proton collisions at s = 13 Te . THE EUROPEAN PHYSICAL JOURNAL. C, PARTICLES AND FIELDS 2021; 81:13. [PMID: 33493254 PMCID: PMC7801369 DOI: 10.1140/epjc/s10052-020-08739-5 10.1140/epjc/s10052-021-08959-3] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Grants] [Track Full Text] [Subscribe] [Scholar Register] [Received: 08/11/2020] [Accepted: 12/07/2020] [Indexed: 10/20/2023]
Abstract
A search for dark matter particles is performed using events with a Z boson candidate and large missing transverse momentum. The analysis is based on proton-proton collision data at a center-of-mass energy of 13Te , collected by the CMS experiment at the LHC in 2016-2018, corresponding to an integrated luminosity of 137fb - 1 . The search uses the decay channels Z → e e and Z → μ μ . No significant excess of events is observed over the background expected from the standard model. Limits are set on dark matter particle production in the context of simplified models with vector, axial-vector, scalar, and pseudoscalar mediators, as well as on a two-Higgs-doublet model with an additional pseudoscalar mediator. In addition, limits are provided for spin-dependent and spin-independent scattering cross sections and are compared to those from direct-detection experiments. The results are also interpreted in the context of models of invisible Higgs boson decays, unparticles, and large extra dimensions.
