Association between lung function and dyspnoea and its variation in the multinational Burden of Obstructive Lung Disease (BOLD) study

BACKGROUND

Dyspnoea is a common symptom of respiratory disease. However, data on its prevalence in general populations and its association with lung function are limited and are mainly from high-income countries. The aims of this study were to estimate the prevalence of dyspnoea across several world regions, and to investigate the association of dyspnoea with lung function.

METHODS

Dyspnoea was assessed, and lung function measured in 25,806 adult participants of the multinational Burden of Obstructive Lung Disease study. Dyspnoea was defined as ≥2 on the modified Medical Research Council (mMRC) dyspnoea scale. The prevalence of dyspnoea was estimated for each of the study sites and compared across countries and world regions. Multivariable logistic regression was used to assess the association of dyspnoea with lung function in each site. Results were then pooled using random-effects meta-analysis.

RESULTS

The prevalence of dyspnoea varied widely across sites without a clear geographical pattern. The mean prevalence of dyspnoea was 13.7 % (SD=8.2 %), ranging from 0 % in Mysore (India) to 28.8 % in Nampicuan-Talugtug (Philippines). Dyspnoea was strongly associated with both spirometry restriction (FVC

CONCLUSION

The prevalence of dyspnoea varies substantially across the world and is strongly associated with lung function impairment. Using the mMRC scale in epidemiological research should be discussed.

Effect of Nutrition and Behavior Modification Program (NBMP) on maternal and neonatal outcomes among hyperglycemic mothers

OBJECTIVE

Hyperglycemic mothers and their offspring are at increased risk of various maternal and neonatal complications such as macrosomia, future type 2 diabetes, and metabolic abnormalities. Early diagnosis and individualized dietary management, exercise, and emotional well-being are expected to reduce these risks. The study aims to identify the effect of the Nutrition and Behavior Modification Program (NBMP) on maternal and neonatal outcomes of hyperglycemic mothers.

PATIENTS AND METHODS

A pre-experimental study was performed among 89 hyperglycemic mothers. Glycemic control at 28 and 36 weeks, weight gain during pregnancy, pre-eclampsia, pregnancy-induced hypertension (PIH), mode of delivery, duration of exercise, emotional well-being, neonates' birth weight, incidence of hypoglycemia, and NICU admission were compared among the study and control groups. The intervention group received an individualized NBMP from their diagnosis of hyperglycemia until delivery.

RESULTS

The results showed a significant difference in blood glucose between the study periods and groups at p<0.05 as per repeated ANOVA. Also, diet scores had a significant influence on BMI and glycemic control at p<0.05. Logistic regression models, adjusted for potential confounders including baseline blood glucose, age, economic status, previous GDM, family history of DM as well as baseline BMI, diet score, physical activity, and maternal well-being score, indicated that the NBMP reduced the blood glucose and BMI significantly at p<0.05 in the study group. NBMP also reduced the risk of SGA/LGA and preterm/post-mature birth, as well as increased the exercise duration and emotional well-being of mothers.

CONCLUSIONS

The study's conclusions draw attention to the possible roles that maternal wellness, physical activity, and diet may have in reducing risks for both hyperglycemic mothers and their newborns. The NBMP resulted in higher adherence to lifestyle changes. Further research on a larger sample of hyperglycemic mothers is recommended to expand the generalizability of the findings.

Effect of Surface Termination with Oxygen and Fluorine on the Electronic Structures and optical spectra of Mn2N Based MXenes

The extensive applications of MXenes, a novel type of layered materials known for their favorable characteristics, have sparked significant interest. This research focuses on investigating the impact of surface functionalization on the behavior of Mn2NX2 (X = O, F) MXenes monolayers using the "Density functional theory (DFT) based full-potential linearized augmented-plane-wave (FP-LAPW)" method. We observe and elucidate the variations in the physical properties of the Mn2NX2 by employing different surface terminations with F and O functional groups. We found that O-termination results in half-metallic behavior, whereas the N-termination evolves metallic characteristics within these MXene systems. Similarly, surface termination has effectively influenced their optical absorption efficiency. For instance, Mn2NO2 and Mn2NF2 effectively absorb UV light of magnitude 50.15×104 cm-1 and 37.71×104 cm-1, respectively. Additionally, they demonstrated prominent refraction and reflection characteristics, comprehensively discussed in the present work. Our predictions offer valuable perspectives into the optical and electronic characteristics of Mn2NX2-based MXenes, presenting the promising potential for implementing them in diverse optoelectronic devices.

Twenty years of participation of racialised groups in type 2 diabetes randomised clinical trials: a meta-epidemiological review

AIMS/HYPOTHESIS

Type 2 diabetes mellitus prevalence is increasing globally and the greatest burden is borne by racialised people. However, there are concerns that the enrolment of racialised people into RCTs is limited, resulting in a lack of ethnic and racial diversity. This may differ depending whether an RCT is government funded or industry funded. The aim of this study was to review the proportions of racialised and white participants included in large RCTs of type 2 diabetes pharmacotherapies relative to the disease burden of type 2 diabetes in these groups.

METHODS

The Ovid MEDLINE database was searched from 1 January 2000 to 31 December 2020. English language reports of RCTs of type 2 diabetes pharmacotherapies published in select medical journals were included. Studies were included in this review if they had a sample size of at least 100 participants and all participants were adults with type 2 diabetes. Industry-funded trials must have recruited participants from at least two countries. Government-funded trials were not held to the same standard because they are typically conducted in a single country. Data including the numbers and proportions of participants by ethnicity and race were extracted from trial reports. The participation-to-prevalence ratio (PPR) was calculated for each trial by dividing the percentage of white and racialised participants in each trial by the percentage of white and racialised participants with type 2 diabetes, respectively, for the regions of recruitment. A random-effects meta-analysis was used to generate the pooled PPRs and 95% CIs across study types. A PPR <0.80 indicates under-representation and a PPR >1.20 indicates over-representation. Risk of bias assessments were not conducted for this study as the objective was to examine recruitment of racialised and white participants rather than evaluate the trustworthiness of clinical trial outcomes.

RESULTS

A total of 83 trials were included, involving 283,122 participants, of which 15 were government-funded and 68 were industry-funded trials. In government-funded trials, the PPR for white participants was 1.11 (95% CI 0.99, 1.24) and the PPR for racialised participants was 0.72 (95% CI 0.60, 0.86). In industry-funded trials, the PPR for white participants was 1.95 (95% CI 1.74, 2.18) and the PPR for racialised participants was 0.36 (95% CI 0.32, 0.42). The limitations of this study include the reliance on investigator-reported ethnicity and race to classify participants as 'white' or 'racialised', the use of estimates for type 2 diabetes prevalence and demographic data, and the high levels of heterogeneity of pooled estimates. However, despite these limitations, the results were consistent with respect to direction.

CONCLUSIONS/INTERPRETATION

Racialised participants are under-represented in government- and industry-funded type 2 diabetes trials. Strategies to improve recruitment and enrolment of racialised participants into RCTs should be developed.

Drought variability assessment using standardized precipitation index, reconnaissance drought index and precipitation deciles across Balochistan, Pakistan

Abstract Drought variability analysis is of utmost concern for planning and efficiently managing water resources and food security in any specific area. In the current study, drought spell occurrence has been investigated in the Balochistan province of Pakistan during the past four decades (1981-2020) using standardized precipitation index (SPI), reconnaissance drought index (RDI), and precipitation deciles (PD) at an annual timescale. Precipitation and temperature data collected from 13 synoptic meteorological stations located in Balochistan were used to calculate the SPI, the RDI, and the PD for calculation of drought severity and duration. Based on these indices, temporal analysis shows adverse impacts of drought spells in Nokkundi during 1991-1993, in Barkhan, Dalbandin, Quetta stations during 1999-2000, whereas Barkhan, Dalbandin, Lasbella, Sibi during 2002-2003, Zhob during 2010-2011, Kalat and Khuzdar during 2014-2015, and Panjgur during 2017-2018. Also, the aridity index for each station was calculated based on the UNEP method shows that major part of Balochistan lies in the arid zone, followed by the hyper-arid in the southwestern part and the semi-arid zones in the northeastern part of the province. SPI and RDI results were found more localized than PD, as PD shows extensive events. Furthermore, principal component analysis shows a significant contribution from all the indices. For SPI, RDI, and PD, the first three principal components have more than 70% share, contributing 73.63%, 74.15%, and 72.30% respectively. By integrating drought patterns, long-term planning, and preparedness to mitigate drought impacts are only possible. The RDI was found more suitable and recommended in case of temperature data availability.

Multiorgan MRI findings after hospitalisation with COVID-19 in the UK (C-MORE): a prospective, multicentre, observational cohort study

INTRODUCTION

The multiorgan impact of moderate to severe coronavirus infections in the post-acute phase is still poorly understood. We aimed to evaluate the excess burden of multiorgan abnormalities after hospitalisation with COVID-19, evaluate their determinants, and explore associations with patient-related outcome measures.

METHODS

In a prospective, UK-wide, multicentre MRI follow-up study (C-MORE), adults (aged ≥18 years) discharged from hospital following COVID-19 who were included in Tier 2 of the Post-hospitalisation COVID-19 study (PHOSP-COVID) and contemporary controls with no evidence of previous COVID-19 (SARS-CoV-2 nucleocapsid antibody negative) underwent multiorgan MRI (lungs, heart, brain, liver, and kidneys) with quantitative and qualitative assessment of images and clinical adjudication when relevant. Individuals with end-stage renal failure or contraindications to MRI were excluded. Participants also underwent detailed recording of symptoms, and physiological and biochemical tests. The primary outcome was the excess burden of multiorgan abnormalities (two or more organs) relative to controls, with further adjustments for potential confounders. The C-MORE study is ongoing and is registered with ClinicalTrials.gov, NCT04510025.

FINDINGS

Of 2710 participants in Tier 2 of PHOSP-COVID, 531 were recruited across 13 UK-wide C-MORE sites. After exclusions, 259 C-MORE patients (mean age 57 years [SD 12]; 158 [61%] male and 101 [39%] female) who were discharged from hospital with PCR-confirmed or clinically diagnosed COVID-19 between March 1, 2020, and Nov 1, 2021, and 52 non-COVID-19 controls from the community (mean age 49 years [SD 14]; 30 [58%] male and 22 [42%] female) were included in the analysis. Patients were assessed at a median of 5·0 months (IQR 4·2-6·3) after hospital discharge. Compared with non-COVID-19 controls, patients were older, living with more obesity, and had more comorbidities. Multiorgan abnormalities on MRI were more frequent in patients than in controls (157 [61%] of 259 vs 14 [27%] of 52; p<0·0001) and independently associated with COVID-19 status (odds ratio [OR] 2·9 [95% CI 1·5-5·8]; padjusted=0·0023) after adjusting for relevant confounders. Compared with controls, patients were more likely to have MRI evidence of lung abnormalities (p=0·0001; parenchymal abnormalities), brain abnormalities (p<0·0001; more white matter hyperintensities and regional brain volume reduction), and kidney abnormalities (p=0·014; lower medullary T1 and loss of corticomedullary differentiation), whereas cardiac and liver MRI abnormalities were similar between patients and controls. Patients with multiorgan abnormalities were older (difference in mean age 7 years [95% CI 4-10]; mean age of 59·8 years [SD 11·7] with multiorgan abnormalities vs mean age of 52·8 years [11·9] without multiorgan abnormalities; p<0·0001), more likely to have three or more comorbidities (OR 2·47 [1·32-4·82]; padjusted=0·0059), and more likely to have a more severe acute infection (acute CRP >5mg/L, OR 3·55 [1·23-11·88]; padjusted=0·025) than those without multiorgan abnormalities. Presence of lung MRI abnormalities was associated with a two-fold higher risk of chest tightness, and multiorgan MRI abnormalities were associated with severe and very severe persistent physical and mental health impairment (PHOSP-COVID symptom clusters) after hospitalisation.

INTERPRETATION

After hospitalisation for COVID-19, people are at risk of multiorgan abnormalities in the medium term. Our findings emphasise the need for proactive multidisciplinary care pathways, with the potential for imaging to guide surveillance frequency and therapeutic stratification.

Omics sciences and precision medicine in Urothelial Carcinoma

Abstract

This comprehensive review explores the potential of omics sciences - such as genomics, transcriptomics, proteomics, and metabolomics - in advancing the diagnosis and therapy of urothelial carcinoma (UC), a prevalent and heterogeneous cancer affecting the urinary tract. The article emphasizes the significant advancements in understanding the molecular mechanisms underlying UC development and progression, obtained through the application of omics approa-ches. Genomic studies have identified recurrent genetic alterations in UC, while transcriptomic analyses have revealed distinct gene expression profiles associated with different UC subtypes. Proteomic investigations have recognized protein biomarkers with diagnostic and prognostic potential, and metabolomic profiling has found metabolic alterations that are specific to UC. The integration of multi-omics data holds promises in refining UC subtyping, identifying therapeutic targets, and predicting treatment response. However, challenges like the standardization of omics technologies, validation of biomarkers, and ethical considerations need to be addressed to successfully translate these findings into clinical practice. Omics sciences offer tremendous potential in revolutionizing the diagnosis and therapy of UC, enabling more precise diagnostic methods, prognostic evaluations, and personalized treatment selection for UC patients. Future research efforts should focus on overcoming these challenges and translating omics discoveries into meaningful clinical applications to improve outcomes for UC patients.

Phase 2 Trial of Anti-PD1 and 8 Gy in 1 Fraction for Relapse/Refractory Myeloma

PURPOSE/OBJECTIVE(S)

Relapsed, refractory multiple myeloma is associated with poor outcome. Role of radiotherapy is mainly for palliation. Anti-PD1 inhibitors have failed to show efficacy in relapsed refractory myeloma patients. A phase 2 trial (NCT03267888) was conducted to see if radiotherapy (8 Gy in 1 fraction) and anti-PD1 (Pembrolizumab) could provide early signals of safety and response.

MATERIALS/METHODS

A prospective single-center phase 2 trial involving patients >18 years of age with ECOG 0-1 was conducted after obtaining IRB approval. Patients had to have ISS stage I-III multiple myeloma that was either relapsed or refractory, an osseous and/or extraosseous lesion that could be radiated, and who were candidates for pembrolizumab. Patients had to have either measurable disease per the International Myeloma Working Group Criteria (IMWG) and/or had to have progressive disease on imaging. Radiotherapy was given on day 0, cycle 1 followed by pembrolizumab (200 mg/kg iv on day 2 or 3, then every 3 weeks +/- 7 days) on day 2-3 for at least 2 years or until progression. Primary endpoint was toxicity. Secondary endpoints were IMWG response, abscopal response, overall survival, and immunological changes in patient's blood. Patients were assessed at 3 months, 6 months, and 12 months IMWG criteria as well as serial PET/CT based imaging. Patients with stable disease or better were continued on the trial. Patients that progressive were removed. Standard statistical analysis was performed, and included Kaplan-Meier to estimate OS and PFS.

RESULTS

From June, 2018 until October, 2021, 32 patients were screened and 25 were enrolled. Of the enrolled patients, 76% were Caucasian, 64% had ECOG 1, and the mean age was 60 years. Prior to enrollment, the mean number of prior lines of therapy that the patients had failed was 5.20 (range: 2 - 11), suggesting a cohort with poor expected outcome. These cohort also had limited alternative options. Toxicity, as its primary endpoint, was acceptable. There were no grade 2 or higher radiation related toxicity within the irradiated volume. Only one case of grade 3 or higher pembrolizumab-related toxicity was noted amongst the 25 patients. Abscopal response was noted in 5 of 25 patients (20% patients). Several patients showed robust reductions in the paraproteins and other myeloma labs, suggesting response to radiotherapy and anti-PD1 combination. These patients were also associated to have a robust CD 8 T cell activation and an abscopal response. The secondary outcomes were better than expected for this cohort.

CONCLUSION

Combination therapy of single-fraction, low-dose radiation therapy with pembrolizumab in patients with relapsed or refractory multiple myeloma is worth assessing in future trials.

Combined Analysis of a Phase III Randomized Trial and Phase II Prospective Trial with Blind Control Matching of Patients Receiving Whole-Lung, Low-Dose Radiation for COVID-19: Full Results and Immunologic Correlates of the RESCUE 1-19 Trial

PURPOSE/OBJECTIVE(S)

Whole-lung, low-dose radiation (LD-RT) for COVID-19 requires randomization and biologic correlates to determine causality and mechanism.

MATERIALS/METHODS

A phase III trial randomized COVID-19 patients to physician's choice of drug therapy with or without LD-RT. Primary endpoint was intubation-free survival (IFS). The trial was designed with 80% power (two-sided log rank, alpha 0.05) to detect a hazard ratio of 0.3 after 12 intubation events. Estimating a 25% event rate, the planned sample size was 84 patients plus 25 to account for declining intubation rates and screen failures. Due to hospitalization declines and other barriers, the trial closed prematurely. Available randomized data were analyzed by intention-to-treat and combined with phase II results and immunologic correlates, using one-sided significance and an alpha of 0.1 to inform future trial design.

RESULTS

From Jun 2020-Jun 2022, 14 patients were randomized on a phase III trial. From Apr 2020-Dec 2020, 42 patients were enrolled on a phase II trial and blindly matched to 40 controls from contemporaneous trials. 96 total patients and 193 blood samples were available for analysis. Mean hospital duration with LD-RT was 12.9 vs 15.4 days in controls (p = 0.12). Oxygen flow rate >15 L/min (26% vs 38%, p = .27), high-flow oxygen >30 L/min (24% vs 38%, p = 0.18), non-invasive positive-pressure >60 L/min (9% vs 27%, p = 0.03), and mechanical ventilation (9% vs 24%, p = 0.05) reduced with LD-RT. Mean supplemented oxygen volume was 171,759 vs 547,626 liters in controls, with daily means of 10 vs 23 L/min (p = 0.03). Radiographs worsened in 43% vs 71% of controls (p = 0.03). Arterial blood gas mean P/F ratios improved 22% after LD-RT vs declined 8% in controls (p = 0.12). Mean days febrile were 1.8 vs 2.9 in controls (p = 0.10). Rate of myocardial injury was 47% vs 40% in controls (p = 0.77). Flow cytometry revealed 4-fold and 30-fold larger expansions, respectively, in CD8- and CD4-positive CD3+PD1+Ki67-high proliferating cytotoxic T-cells (300% vs 75% expansion, p = 0.07) and helper T-cells (200% expansion vs 6% contraction, p = 0.03) at day 7. In the randomized cohort, mean oxygen volume fell 75% with LD-RT to 78,336 vs 316,786 liters in controls (p = 0.13), mean flow rates were 5.1 vs 18.4 L/min (p = 0.13), radiographs worsened in 50% vs 100% (p = .17), P/F ratios improved 31% vs declined 68% in controls (p = 0.03), hospital duration was 8.9 vs 11.5 days (p = 0.22), and zero LD-RT patients vs one control intubated.

CONCLUSION

Combined analysis of a phase II/III randomized trial suggests that LD-RT prevents ventilation, reduces supplemental oxygen need, improves clinical course, and enhances immune response. LD-RT may have both immediate direct effects and delayed enhanced immunity in COVID-19. Larger multi-institutional trials are justified.

A point-prevalence study of body mass indices in HIV-positive and HIV-negative patients admitted to hospital with COVID-19 in South Africa

Background

Obesity is now well recognised as a risk factor for severe COVID-19, but the true prevalence of obesity in hospitalised adults with COVID-19 remains unclear because formal body mass indices (BMIs) are not routinely measured on admission.

Objectives

To describe the true prevalence of obesity measured by the BMI, and associated comorbidities, in patients hospitalised with severe COVID-19, including people with HIV (PWH).

Methods

We conducted a point-prevalence study of measured BMI in consecutive patients with severe COVID-19 admitted to the medical COVID-19 wards in a tertiary academic hospital in Cape Town, South Africa (SA). Patients were enrolled over a 2-week period during the peak of the first COVID-19 wave in SA.

Results

We were able to measure the BMI in 122 of the 146 patients admitted during the study period. The prevalence of HIV was 20% (n=24/122). Most of the participants were overweight or obese (n=104; 85%), and 84 (68.9%) met criteria for obesity. The mean (standard deviation) BMI was 33 (7.5), and 34.5 (9.1) in PWH. Of PWH, 83% (n=20/24) were overweight or obese and 75% (n=18) met criteria for obesity. Multimorbidity was present in 22 (92%) of PWH.

Conclusion

We found that most patients, including PWH, met criteria for being overweight or obese. The high prevalence of obesity in PWH and severe COVID-19 reinforces the need for targeted management of non-communicable diseases, including obesity, in PWH.

Study synopsis

What the study adds. We found that the true prevalence of obesity, including in people with HIV (PWH), measured with the formal body mass index in hospitalised patients with severe COVID-19 was much higher than reported previously.Multimorbidity was present in over half of all patients, and in 92% of PWH. Implications of the findings. Urgent public health measures are required to tackle the rise in obesity, including in low- and middle-income countries.HIV care must integrate management of non-communicable diseases, including obesity.The pathogenic mechanism of the link between obesity and severe COVID-19 needs further research.

Prevalence and determinants of chronic respiratory diseases in adults in rural Sudan

BACKGROUND: Chronic respiratory diseases (CRDs) greatly contribute to worldwide mortality. Despite new data emerging from Africa, prevalence estimates and determinants of CRDs in rural settings are limited. This study sought to extend the existing research conducted in urban Sudan by conducting a rural comparison.METHODS: Participants aged ≥18 years (n = 1,850), living in rural Gezira State completed pre-and post-bronchodilator spirometry and a questionnaire. Prevalence of respiratory symptoms and spirometric abnormalities were reported. Regression analyses were used to identify risk factors for CRDs.RESULTS: Prevalence of chronic airflow obstruction (CAO) was 4.1% overall and 5.5% in those aged ≥40 years. Reversibility was seen in 6.4%. Low forced vital capacity (FVC) was seen in 58.5%, and at least one respiratory symptom was present in 40.7% of the participants. CAO was more common among people aged 60-69 years (OR 2.07, 95% CI 1.13-3.82) and less common among highly educated participants (OR 0.50, 95% CI 0.27-0.93). Being underweight was associated with lower FVC (OR 3.07, 95% CI 2.24-4.20).CONCLUSIONS: A substantial burden of CRD exists among adults in rural Sudan. Investment in CRD prevention and management strategies is needed.

Prevalence and determinants of chronic respiratory diseases in adults in Sudan

BACKGROUND: Chronic respiratory diseases (CRDs) are considered a significant cause of morbidity and mortality worldwide, although data from Africa are limited. This study aimed to determine the prevalence and determinants of CRDs in Khartoum, Sudan.METHODS: Data were collected from 516 participants aged ≥40 years, who had completed a questionnaire and undertook pre- and post-bronchodilator spirometry testing. Trained field workers administered the questionnaires and conducted spirometry. Survey-weighted prevalence of respiratory symptoms and spirometric abnormalities were estimated. Regression analysis models were used to identify risk factors for chronic lung diseases.RESULTS: Using the Third National Health and Nutrition Examination Survey, 1988-1994 (NHANES III) reference equations, the prevalence of chronic airflow obstruction (CAO) was 10%. The main risk factor was older age, 60-69 years (OR 3.16, 95% CI 1.20-8.31). Lower education, high body mass index and a history of TB were also identified as significant risk factors. The prevalence of a low forced vital capacity (FVC) using NHANES III was 62.7% (SE 2.2) and 11.3% (SE 1.4) using locally derived values.CONCLUSION: The prevalence of spirometric abnormality, mainly low FVC, was high, suggesting that CRD is of substantial public health importance in urban Sudan. Strategies for the prevention and control of these problems are needed.

A theoretical investigation of the lead-free double perovskites halides Rb2 XCl6 (X = Se, Ti) for optoelectronic and thermoelectric applications

In this study, structural, electronic, optical, thermoelectric, and thermodynamics properties of vacancy-ordered double perovskites Rb₂ XCl₆ (X = Se, Ti) were explored theoretically. The results revealed that Rb2SeCl6 and Rb₂ TiCl₆ are indirect band gap (E_g ) semiconductors with E_g values of 2.95 eV, and 2.84 eV respectively. The calculated properties (phonons, elastic constant, Poisson's ratio, and Pugh's ratio) revealed that both materials are dynamically and chemically stable and can exhibit brittle (Rb₂ SeCl₆ ) and ductile (Rb₂ TiCl₆ ) nature. From the analysis of optical parameters, it was noticed that the refractive index of the materials has a value of 1.5-2.0 where light absorption was found from the visible to the ultraviolet region. The thermoelectric properties determined by using the BoltzTrap code demonstrated that at room temperature, the Figure of merit (ZT) was found to be 0.74 and 0.76 for Rb₂ SeCl₆ and Rb₂ TiCl₆ , respectively. Despite a moderate value of ZT in such materials, further studies might explore effective methods for tuning the electronic band gap and improving the thermoelectric response of the material for practical energy production applications.

First-principle investigations of structural, electronic, thermal, and mechanical properties of AlP1-xBix alloys

CONTEXT

In this work, a comprehensive study concerning the physical properties of ternary alloys system (AlP_1-xBi_x) at different concentrations is presented. The obtained results from our first-principle calculations are compared with previously reported studies in the literature and discussed in detail. Our computed results are found in a nice agreement where available with earlier reported results. Electronic band structures at the above-mentioned concentrations are also determined. Likewise, the impact of the varying temperature and pressure on Debye temperature, heat capacity, and entropy is analyzed as well. Furthermore, elastic constants and related elastic moduli results are also computed. Our results show that alloys are stable and found to be in brittle nature. This is the first quantitative study related to ternary alloys (AlP_1-xBi_x) at mentioned concentrations. We soon expect the experimental confirmation of our predictions.

METHOD

The calculations are performed, at concentrations x=0.0, 0.25, 0.5, 0.75, and 1.0 by using the "full potential (FP) linearized (L) augmented plane wave plus local orbital (APW+lo) method framed within density functional theory (DFT)" as recognized in the "WIEN2k computational code". The "quasi-harmonic Debye model" approach is employed to determine the thermal properties of the title alloys.

347 LONELINESS AMONGST OLDER INPATIENTS IN THE CONTEXT OF COVID-RELATED VISITING RESTRICTIONS

Background

Loneliness can affect people at all stages of life, but appears to be more closely linked to adverse health outcomes such as quality of life and healthcare use amongst older people. There are concerns that restrictions on hospital visits due to infection control policies related to the COVID-19 pandemic may exacerbate loneliness amongst older inpatients. The aim of this study is to quantify the burden of loneliness amongst older inpatients on a specialist geriatric medicine unit.

Methods

The study site is a large urban university teaching hospital with a 150-bed specialist geriatric medicine unit, comprising acute medical, rehabilitation and long-stay wards. The University of California, Los Angeles (UCLA) Scale was used to measure symptoms of loneliness with scores≥43 indicating high levels of loneliness.

Results

Over 84% of patients were lonely at some time while in hospital, with over one-third (24/76) reporting high levels of loneliness. The mean number of days since last visit from a relative or friend for patients reporting high degrees of loneliness was 11.4 (1.2 – 21.6) days, compared to 5.2 (3.2 – 7.1) days for those with reporting lower levels or no loneliness, though confidence intervals overlapped (p = 0.108). Similarly, patients with higher levels of loneliness had a longer length of stay (68.2 (49.4 – 87.1) compared to 47.9 (33.1 – 62.6) but again findings did not reach significance (p = 0.098). Linear regression models, controlling for competing covariates, found that depressive symptoms, were independently associated with burden of loneliness with a β-Coefficient = 10.69 (5.00 – 16.39).

Conclusion

Loneliness is particularly prevalent amongst older inpatients, with a trend towards higher levels of loneliness in those with less frequent visits. Interventions to help older people stay in touch with family and friends, and maintain social connectedness while in hospital, allowing for COVID-related restrictions, would be welcome, particularly for those with longer lengths of stay.

345 HOW PREVALENT ARE UNDETECTED DEPRESSIVE SYMPTOMS AMONGST OLDER HOSPITAL INPATIENTS?

Background

Depression in later life can have a profound effect on quality of life, functional independence, healthcare use and early mortality. For multiple reasons however, depression in later life may often go undetected. The aim of this study is to ascertain the point prevalence of depressive symptoms on a specialist geriatric medicine unit, examining the rate of detection of clinically significant symptoms.

Methods

The study site is a large urban university teaching hospital with a 150-bed specialist geriatric medicine unit, comprising acute medical, rehabilitation and long-stay wards. Depressive symptoms were assessed using the Centre for Epidemiological Studies Depression Scale (CES-D) with a score ≥16 indicating significant symptoms. Medical notes were examined for documentation of screening for/assessment of depression since admission. Patients were included if they were aged ≥70 years, a current inpatient and able to give informed consent.

Results

Almost 62% (47/76) of the study sample (Mean age 83 years, 66% female) met criteria for significant depressive symptoms. Almost-half (23/47, 49%) of patients with significant depressive symptoms were screened for depression (either with a structured screening tool, a documented mood assessment or review by psychiatry) while in hospital. The mean length of stay for patients with depressive symptoms who had not yet been screened for depression was 42.7 (23.2 – 62.2) days and over 70% had been in hospital for at least 10 days, with almost two-thirds (15/24, 65%) currently residing on an acute geriatric medicine ward (rather than a rehabilitation or long stay ward).

Conclusion

Our study demonstrates a high burden of depressive symptoms amongst older inpatients, with almost 2 in 3 meeting criteria for clinically significant symptoms. Less than half of those with clinically significant symptoms were screened for depression however, representing an important missed opportunity to identify, and possibly treat, depression.

Impact of cardiac resynchronisation therapy in patients with cardiac sarcoidosis

Background

Implantation of a device is usually required in cardiac sarcoidosis (CS) patients presenting with advanced conduction abnormalities or ventricular arrhythmias. A cardiac resynchronisation therapy (CRT) device is often chosen in patients with concomitant left ventricular systolic impairment. The role of CRT in CS is not well established.

Purpose

To describe the cohort of CS patients with CRT device in situ in our hospital focusing on the short-term effect in serial echocardiography and long-term outcomes on morbidity and mortality.

Methods

All consecutive CS patients with a CRT device in situ were identified in our CS database (2005–2022). A confident CS diagnosis was provided after review of all relevant clinical and imaging baseline data in our CS multi-disciplinary meeting and a consensus decision for CRT-D implantation was made based on international guidelines. All patients were followed up for at least 6 months with serial echocardiography. Serial data regarding symptoms, rhythm disturbance and echocardiographic parameters were obtained and comparisons were performed using Wilcoxon signed rank test.

Results

A total of 51 CS patients with CRT-D were identified (mean age: 57±10 years old). Patients were male predominant (64.7%) and Caucasian in origin (86.2%). Extra-cardiac sarcoidosis was confirmed histologically in 33 (64.7%) patients. The prevalence of smoking, diabetes, hypertension and ischaemic heart disease was 27.5%, 21.6%, 49.0% and 7.8% respectively. At the time of device implantation or during follow-up, 43 (84.3%) patients were found to have active cardiac sarcoidosis on cardiac PET.

Post CRT implantation there was a significant difference in LV ejection fraction (35.9±15.0% vs 42.2±14.1%, p&lt;0.001), LV end-systolic diameter (4.90±1.46 cm vs 4.62±1.32 cm, p=0.012) and LV end-diastolic diameter (5.99±1.18 cm vs 5.66±1.06 cm, p&lt;0.001). No significant changes were observed in the right ventricular function (p=0.09) and severity of mitral regurgitation (p=0.40). There was one patient who experienced acute heart failure decompensation admission within six months of CRT-D implantation. The New York Heart Association (NYHA) class improved in 26 patients (51.0%), worsened in 4 (7.8%) patients and remained the same in 21 (41.2%) patients at 6 months post CRT-implantation. During the mean follow up of 47.6 months, the composite end-point of death and cardiac transplantation was reached in 9 (17.6%) patients (8 deaths and 1 cardiac transplantation). 5 patients had major complications including a large haematoma, a small atrio-septal defect, haemothorax, device associated endocarditis and lead fracture. Minor wound infections were seen in 3 patients and 4 patients received inappropriate shock or anti-tachycardia pacing.

Conclusions

CRT in cardiac sarcoidosis patients is associated with short-term improvement in LV remodelling and functional status but over a four year follow up, morbidity and mortality are common.

429 Clinical Audit Ankle Fractures

Aim

Ankle fractures are common among adult age group with an incidence of 174 per 100000 per year and they pose serious problems in management of geriatric age group because of osteoporotic bone. Our aim of current clinical audit was to introduce changes in current clinical practice by recommendations according to Standard BOAST guidelines of management of Ankle Fractures.

Method

Clinical Audit was carried out in Department of Orthopedics Benazir Bhutto Hospital in Outdoor and Emergency in March 2021 in patients of age group 20–70 years taking 50 patients for pre- and post-audit assessment. Emergency, Outdoor Slips were evaluated according to Standards of Practice formulated. Then a presentation was given to medical staff on Guidelines of Ankle fractures management, and they were informed about the deficiencies in their documentation and management. Panaflexes of Guidelines were displayed in ER, ward and then re-evaluation was done after 4 weeks in April 2021 using proformas in which clinical notes, discharge certificates and emergency slips were used for data analysis and observing improvement.

Results

The results of asymmetric data were calculated by Fischer Exact Test and with a p-value of &lt;0.05 considered as significant. Results were very pleasing as they showed great improvements in documentation as well as management of patients in accordance with the set guidelines and protocols.

Conclusion

Clinical Audits should be carried out on regular basis in hospital settings as they help to improve the standards of care as well as proper documentation which has medico-legal importance.

431 Writing the Right Way! Improvement of Operation Notes in an Orthopaedic Ward – a Closed Loop Audit

Introduction

Operation notes are recognized as standard for documentation of details of operation but still it's often neglected. Proper documentation is necessary as it is correlated with good patient care, quality assurance, future decisions, and medico-legal issues.

Aim

The objective of this study is twofold: one to compare the documentation of notes against standard RCS (Royal College of Surgeons) guidelines and secondly making sure that surgeons follow these by educating them through presentations, brochures, aide memoires and introduction of proformas.

Method

We prospectively studied 50 post-op notes against standard RCS guidelines consecutively both pre and post intervention. Asymmetric data was analyzed after 4 weeks using the Fischer-Exact Test and statistical significance was set as &lt;0.05.

Results

A total of 18 guidelines were audited. First loop showed deficiencies in fields of elective/emergency, operative diagnosis, operative findings, complications, extra procedure performed, tissue removed/added, details of closure, blood loss and antibiotic prophylaxis. After intervention documentation improved and percentages rose and reached almost 100%.

Conclusion

Proper documentation is of great importance as it carries both medical and legal implications. Three step intervention showed remarkable improvement in documenting of these operation notes according to standard RCS guidelines.

Clinical characteristics with inflammation profiling of long COVID and association with 1-year recovery following hospitalisation in the UK: a prospective observational study

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.

The Dangers of Reused Personal Protective Equipment: Healthcare Workers and Workstation Contamination

Background

Personal protective equipment (PPE) is essential to protect healthcare workers (HCWs). The practice of reusing PPE poses high levels of risk for accidental contamination by HCWs. Scarce medical literature compares practical means or methods for safe reuse of PPE while actively caring for patients.

Methods

In this study, observations were made of 28 experienced clinical participants performing five donning and doffing encounters while performing simulated full evaluations of patients with coronavirus disease 2019. Participants' N95 respirators were coated with a fluorescent dye to evaluate any accidental fomite transfer that occurred during PPE donning and doffing. Participants were evaluated using blacklight after each doffing encounter to evaluate new contamination sites, and were assessed for the cumulative surface area that occurred due to PPE doffing. Additionally, participants' workstations were evaluated for contamination.

Results

All participants experienced some contamination on their upper extremities, neck and face. The highest cumulative area of fomite transfer risk was associated with the hook and paper bag storage methods, and the least contamination occurred with the tabletop storage method. Storing a reused N95 respirator on a tabletop was found to be a safer alternative than the current recommendation of the US Centers for Disease Control and Prevention to use a paper bag for storage. All participants donning and doffing PPE were contaminated.

Conclusion

PPE reusage practices pose an unacceptably high level of risk of accidental cross-infection contamination to healthcare workers. The current design of PPE requires complete redesign with improved engineering and usability to protect healthcare workers.

OP0065 INFLIXIMAB BIOSIMILAR-TO-BIOSIMILAR SWITCHING IN PATIENTS WITH INFLAMMATORY RHEUMATIC DISEASES: CLINICAL OUTCOMES IN REAL-WORLD PATIENTS FROM THE DANBIO REGISTRY

Background

In routine care, biosimilar-to-biosimilar infliximab switching may occur to save costs (=non-medical switching). Previous studies have investigated the efficacy and safety of switches from originator infliximab to a corresponding biosimilar in patients with inflammatory rheumatic diseases (1). However, the outcomes after switching from one infliximab biosimilar to a second infliximab biosimilar remain scarcely investigated.

Denmark has recently conducted a nationwide mandatory infliximab biosimilar-to-biosimilar switch.

Objectives

To investigate the effectiveness of infliximab biosimilar-to-biosimilar switch (CTP-13 to GP1111) among patients with RA, PsA and AxSpA, including patients who had previously switched from originator (originator-experienced) to CT-P13 as well as patients who were originator-naïve.

Methods

Observational cohort study based on DANBIO registry (for clinical data upon switch =baseline) linked with national patient registries (to identify prior comorbidities). Patients with RA, PsA or AxSpA who performed a biosimilar-to-biosimilar switch from CT-P13 to GP1111 between April 1st 2019 and February 1st 2020 were included. Patient were divided into two groups: originator-naïve and originator-experienced. Main outcomes in the two groups were one-year GP1111 treatment retention (Kaplan Meier “drug survival curves”) and changes in disease activity 4 months before versus 4 months after switch in individual patients. Also, factors associated with GP1111 treatment retention for both groups combined were explored with Cox proportional hazard regression analyses, stratified by diagnosis (univariate-, age-and gender adjusted and fully adjusted). Analyses were adjusted for relevant clinical factors (for details: see Table 1)

Table 1.

Results

In total, 1,605 patients underwent an infliximab biosimilar-to-biosimilar switch and were included; 1,171 were originator-naïve and 434 were originator-experienced, 685 RA/314 PsA/606 AxSpA, median disease duration was 9 years, 42% were in DAS28/ASDAS remission at the time of switch.

At one year, 83% (95% CI 81-85) of the originator-naive and 92% (95% CI 90-95) of the originator-experienced switchers maintained GP1111 treatment (Figure 1). Changes in disease activity 4 months pre- and post-switch were close to zero for all disease activity measures (e.g. DAS28, ASDAS, VAS pain, not shown).

The risk of GP1111 withdrawal was lower in originator-experienced compared to originator-naïve patients in patients with RA and PsA: HR 0.4 (95% CI 0.2-0.9, p-value 0.01) and HR 0.1 (0.1-0.6, p=0.01), but not significantly for AxSpA 0.56 (0.27-1.13, p=0.1). Across all indications, lower disease activity at baseline (DAS28/ASDAS remission) was associated with higher retention (Table 1).

Conclusion

Biosimilar-to-biosimilar infliximab switch was effective and well-tolerated in >1,500 real-world patients. Retention was higher in originator-experienced switchers and patients, who were in remission at the time of the switch, suggesting retention to be more affected by patient-related than drug-related factors.

Physical performance among post-COVID and non-COVID individuals: a comparative study

In this comparative cross-sectional study, we compare the physical performance among post-COVID and non-COVID subjects. A sample of 64 subjects recovered from COVID-19 and 64 subjects who were not infected with COVID-19 were recruited for the study. Both groups were tested for physical performance by 30-s sit-to-stand test, 6-min walk test, and HUMAC balance system. The findings of the present study reveal that there was a significant difference in physical performance between both the groups. In conclusion, this study demonstrated that physical performance is impaired in the post-COVID subjects as compared to the matched non-COVID subjects. Therefore, physical therapy exercise program/regimen should be a part of recovery from COVID-19.

Effect of Cardiopulmonary Bypass on Blood and Coagulation Profile in Patients Undergoing Cardiac Surgery

This study was carried out in the department of cardiac surgery, Bangabandhu Sheikh Mujib Medical University (BSMMU), Dhaka, Bangladesh from July 2014 to April 2016. This study aims to evaluate the inadvertent effect of cardiopulmonary bypass on complete blood count and coagulation profile. This study was also compared the hemostatic parameters between patients undergoing elective cardiac surgery with CPB and without CPB. A total of 55 patients were included in this study. Among them 20 patients (Group A) were selected for elective cardiac surgery without cardiopulmonary bypass (CPB), 20 patients (Group B) with cardiopulmonary bypass time less than 90 minutes and 15 patients (Group C) were included with cardiopulmonary bypass time either 90 minutes or more. The mean age were 51.5±4.7 years ranging from 40-57 years in Group A, 33.2±10.2 years ranging from 18-50 years in Group B and 34.2±11.4 years ranging from 18-57 years in Group C. The difference of age was statistically significant (p<0.05) among three groups. The difference of post-operative mean hemoglobin and RBC value, WBC and Platelet count on arrival at the intensive care unit, at 48 hours and at 7 days after surgery were statistically significant (p<0.05) in the three groups. However, on arrival at Intensive Care Unit, after 48 hours and at 7 days after surgery, the change of coagulation profile like mean fibrinogen level, bleeding time, clotting time and prothrombin time were statistically significant (p<0.05) among the groups. Patient with long cardiopulmonary bypass time had shown blood and coagulation profile abnormality and it can be minimized if we can curtail the bypass time.

Clinical presentation, disease course, and outcome of COVID-19 in hospitalized patients with and without pre-existing cardiac disease: a cohort study across 18 countries

AIMS

Patients with cardiac disease are considered high risk for poor outcomes following hospitalization with COVID-19. The primary aim of this study was to evaluate heterogeneity in associations between various heart disease subtypes and in-hospital mortality.

METHODS AND RESULTS

We used data from the CAPACITY-COVID registry and LEOSS study. Multivariable Poisson regression models were fitted to assess the association between different types of pre-existing heart disease and in-hospital mortality. A total of 16 511 patients with COVID-19 were included (21.1% aged 66-75 years; 40.2% female) and 31.5% had a history of heart disease. Patients with heart disease were older, predominantly male, and often had other comorbid conditions when compared with those without. Mortality was higher in patients with cardiac disease (29.7%; n = 1545 vs. 15.9%; n = 1797). However, following multivariable adjustment, this difference was not significant [adjusted risk ratio (aRR) 1.08, 95% confidence interval (CI) 1.02-1.15; P = 0.12 (corrected for multiple testing)]. Associations with in-hospital mortality by heart disease subtypes differed considerably, with the strongest association for heart failure (aRR 1.19, 95% CI 1.10-1.30; P < 0.018) particularly for severe (New York Heart Association class III/IV) heart failure (aRR 1.41, 95% CI 1.20-1.64; P < 0.018). None of the other heart disease subtypes, including ischaemic heart disease, remained significant after multivariable adjustment. Serious cardiac complications were diagnosed in <1% of patients.

CONCLUSION

Considerable heterogeneity exists in the strength of association between heart disease subtypes and in-hospital mortality. Of all patients with heart disease, those with heart failure are at greatest risk of death when hospitalized with COVID-19. Serious cardiac complications are rare during hospitalization.

Exposing the incidence of ileus in pelvic and acetabular fractures: a retrospective case analysis

BACKGROUND

Paralytic ileus is a temporary inhibition of gastrointestinal mobility in the absence of mechanical obstruction. Ileus has previously been observed in up to 40% of patients undergoing bowel surgery, leading to increased morbidity and length of stay. Pelvic and acetabular fractures are often caused by high energy trauma and are associated with a risk of visceral injury.  Prior to this study, there were no reported figures for the incidence of ileus in patients presenting with pelvic and/or acetabular fractures.

METHODS

All patients over the age of 16 presenting to a major trauma centre throughout 2019 were included. Data collected included patient demographics, injury pattern, fracture management and presence of ileus. As in previous studies, patients were identified as having ileus if they failed to tolerate an oral diet and open their bowels for more than three days (GI-2). Analysis assessed risk factors for ileus as well as its effect on length of stay.

RESULTS

An incidence of ileus of 40.35% was observed in the 57 included patients. Across all patients, ileus was three times more common in patients with a diagnosis of diabetes mellitus (p= 0.56) and 2.5 times more common in the presence of an open pelvic/ acetabular fracture (p= 0.73). Length of stay was significantly longer in patients under 65 years identified as having ileus (p= 0.046). Gender, age, opiate use, fracture management and surgical approach were not identified as risk factors for ileus.

CONCLUSION/ FINDINGS

This is the first study to report the incidence of and risk factors for ileus following admission with pelvic and/or acetabular fractures. Due to the morbidity and cost associated with this condition, further research is required to assess the effect of interventions to reduce its incidence in this patient subgroup.

Use of race, ethnicity, and ancestry data in health research

Race, ethnicity, and ancestry are common classification variables used in health research. However, there has been no formal agreement on the definitions of these terms, resulting in misuse, confusion, and a lack of clarity surrounding these concepts for researchers and their readers. This article examines past and current understandings of race, ethnicity, and ancestry in research, identifies the distinctions between these terms, examines the reliability of these terms, and provides researchers with guidance on how to use these terms. Although race, ethnicity, and ancestry are often treated synonymously, they should be considered as distinct terms in the context of health research. Researchers should carefully consider which term is most appropriate for their study, define and use the terms consistently, and consider how their classification may be used in future research by others. The classification should be self-reported rather than assigned by an observer wherever possible.

Mature tertiary lymphoid structures in lung adenocarcinoma are associated with better progression free survival

Introduction/Objective

The presence of inducible lymphoid structures known as tertiary lymphoid structures in the tumor microenvironment has been shown to correlate with positive clinical outcome. However, the maturation states of lymphoid aggregates in lung adenocarcinoma are not completely understood.

Methods/Case Report

Seventy tumor samples from 69 patients diagnosed with lung adenocarcinoma (Stages I to III) between 2013 and 2015 were included in the study. The presence and maturation states of the lymphoid structures within the tumors were evaluated by conventional and 26 samples were further analyzed by multiplexed immunohistochemistry of formalin fixed paraffin embedded tissues and then quantified. Mature lymphoid follicles containing germinal centers were identified by the presence of CD21+ and BCL-6+ cells in an organized configuration within tight clusters of T and B cells.

Results (if a Case Study enter NA)

Samples with fully mature lymphoid structures (germinal centers) had larger tumors and higher disease stage. The number of mature lymphoid structures correlated with the total number of lymphoid aggregates present in the tumor microenvironment. Additionally, tumor samples with ≥10 mature lymphoid structures had more primary follicles. While there was no difference in overall survival, progression free survival was significantly longer in patients who had ≥10 mature lymphoid structures in comparison with patients who had &lt;10 mature structures.

Conclusion

In conclusion, a spectrum of lymphoid aggregates in different stages of maturation are present in lung adenocarcinoma. An increase in the number of mature lymphoid structures may be associated with progression free survival in patients with lung adenocarcinoma.

1065 Exposing the Incidence of Ileus in Pelvic and Acetabular Fractures: A Retrospective Case Analysis

Background

Paralytic ileus is a temporary inhibition of gastrointestinal mobility in the absence of mechanical obstruction. Ileus has previously been observed in up to 40% of patients undergoing bowel surgery, leading to increased morbidity and length of stay. Pelvic and acetabular fractures are often caused by high energy trauma and are associated with a risk of visceral injury. This is the first study to report the incidence of and risk factors for ileus following admission with pelvic and/or acetabular fractures.

Method

All patients over the age of 16 presenting to a major trauma centre throughout 2019 were included. Data included patient demographics, injury pattern, fracture management and presence of ileus. Previous studies identified patients as having ileus if they failed to tolerate an oral diet and open their bowels for more than three days (GI-2). Analysis assessed risk factors for ileus as well as its effect on length of stay.

Results

An incidence of ileus of 40.35% was observed in the 57 included patients. Ileus was three times more common in patients with a diagnosis of diabetes mellitus (p = 0.56) and 2.5 times more common in the presence of an open pelvic/acetabular fracture (p = 0.73). Length of stay was significantly longer in patients under 65 years identified as having ileus (p = 0.046). Gender, age, opiate use, fracture management and surgical approach were not identified as risk factors.

Conclusions

The authors have identified the essentiality of early risk factor identification and hope to encourage further research to create a prognostic tool.

533 Diverticular Disease and Diet: Are We Doing Enough?

Introduction

Diverticular disease (DD) is a major burden on healthcare systems globally, especially in the western world. DD accounts for the second most common indication for elective colorectal resections, with each resection costing the NHS a minimum of £5000. Since dietary advice is an integral part of the management of DD, we aim to investigate the proportion of patients that receive documented dietary advice or guidance on their stay in hospital.

Method

A list of all admissions related to DD from June to November 2019 was obtained from the HIPE Department in Princess Royal University Hospital. Our Electronic patient record system was used to extract information regarding patient demographics, length of stay in hospital and the presence of documented evidence that dietary advice was given to patients.

Results

A total of 57 patients were admitted due to DD over a six-month period in 2019. 41 were female and 16 were male. They had a mean age of 67.1 and an average length of stay of 6.3 days. 12 of the 57 (21%) had some form of surgery either as an emergency or electively after discharge. Only 15 (26%) received dietary advice of which only 9 were referred to a dietician.

Conclusions

DD is a major contributor to surgical admissions requiring both elective and emergency surgery. It is largely a preventable disease; hence health care staff should take more initiative to highlight the importance of lifestyle modification to patients whenever the opportunity arises, with the target to benefit public health and free healthcare resources.

Trends and instigators among young adolescent suicide in the United States

OBJECTIVES

The present investigation examined the role of factors involved in suicide ideation and suicide attempt using a nationally representative sample of US high school students.

METHODS

Data were collected from students in Grades 9-12 as part of the Youth Behavioral Survey (n = 11,328). Logistic regression models were used to examine factors associated with suicide ideation and suicide attempt. Variables included demographic characteristics (grade, sex, and race), psychosocial factors (physical fighting, sexual violence, sports participation, bullying, and electronic bullying), and substance use (cigarette usage, marijuana usage, and alcohol usage).

RESULTS

The factor most associated with suicide ideation was bullying (either electronic or physical), whereas the factor most associated with suicide attempt was sexual violence followed closely by physical bullying.

CONCLUSIONS

The multitude of instigators and commonality among gender, ethnicity, and socio-economic status give an indication of how to prevent suicide and who to target information regarding the hazards of suicide.

Interferon-gamma release assays for latent tuberculosis infection screening in Canadian federal correctional facilities

BACKGROUND: The correctional setting presents an opportunity for latent TB infection (LTBI) screening in an otherwise difficult to reach demographic. We evaluate factors associated with the fidelity of the tuberculin skin test (TST) and interferon-gamma release assay (IGRA), specifically the QuantiFERON^®-TB Gold In-Tube assay (QFT-GIT), explain factors associated with discordance, and report LTBI treatment outcomes.METHODS: We describe the association between demographic and clinical variables, and predictors of concordance with IGRA using univariate logistic regression in a population of TST-positive inmates. We report outcomes among those offered LTBI treatment.RESULTS: We observed concordance between TST and QFT-GIT in 90 of 306 (29.4%) inmates. Persons with TST+/QFT-GIT+ results were less likely to be male (OR 3.94, 95% CI 1.73-8.97) or have a BCG vaccination history (OR 0.34, 95% CI 0.12-0.95), and more likely to be foreign-born (P < 0.001). Of the 108 inmates offered LTBI treatment, 65 (60.1%) accepted and 51 (78.0%) completed. TST/QFT-GIT discordance has not been associated with disease during follow-up.CONCLUSION: Our findings suggest that TST/QFT-GIT discordance in Canadian federal inmates is common; however, low-risk of disease progression in those with discordance suggests that a shift towards IGRA-based screening is warranted and feasible.

Flow-Diversion Treatment for Unruptured ICA Bifurcation Aneurysms with Unfavorable Morphology for Coiling

BACKGROUND AND PURPOSE

Few reports described flow diversion for ICA bifurcation aneurysms. Our aim was to provide further insight into flow diversion for ICA bifurcation aneurysms difficult to treat with other strategies.

MATERIALS AND METHODS

Consecutive patients receiving flow diverters for unruptured ICA bifurcation aneurysms were collected. Aneurysm occlusion (O'Kelly-Marotta grading scale) and clinical outcomes were evaluated.

RESULTS

Twenty saccular ICA bifurcation aneurysms were treated with the Pipeline Embolization Device deployed from the M1 to the ICA, covering the aneurysm and the A1 segment. All patients presented with an angiographic visualized contralateral flow from the anterior communicating artery. Mean aneurysm size was 6.5 (SD, 3.2) mm (range, 4.5-20 mm). All lesions had an unfavorable dome-to-neck ratio (mean/median, 1.6/1.6; range, 0.8-2.8; interquartile range = 0.5) or aspect ratio for coiling (mean/median = 1.5/1.55; range, 0.8-2.5; interquartile range = 0.6). One was a very large aneurysm (20 mm). Nineteen medium-sized lesions were completely occluded during the angiographic follow-up (13 months). No cases of aneurysm rupture or retreatment were reported. No adverse events were described. Aneurysm occlusion was associated with the asymptomatic flow modification of the covered A1 that was occluded and contralaterally filled among 10 patients (50%), narrowed among 9 patients (45%), and unchanged in 1 subject (5%). There was no difference in the mean initial diameter of the occluded (2.1 [SD 0.4] mm; range, 1.6-3 mm) and narrowed (2 [SD, 0.2] mm; range, 1.7-2.6 mm) A1 segments.

CONCLUSIONS

Medium-sized unruptured ICA bifurcation aneurysms with unfavorable morphology for coiling can be treated with M1 ICA flow diversion. Aneurysm occlusion is associated with flow modifications of the covered A1 that seems safe in the presence of a favorable collateral anatomy through the anterior communicating artery complex.

893 Intestinal Stoma - A challenge for the Patient

Introduction

Formation of intestinal stoma is a widely performed surgical procedure worldwide. It is associated with variable complications which can impact physical and mental health of the patient. The purpose of this study is to study the aspects (indications, complications, change in quality-of-life etc) and make necessary recommendations for quality improvement and to make patient experience better.

Method

study included 150 patients with stoma formation. Data categorised according to indications, complications, based on their response to change to quality of life.

Results

A total of 150 patients were included in this study. There were 89 male (59.3%), female (40.6%). 63 patients (42%) had loop ileostomy;38 patients (25.3%) had transverse colostomy. 77 patients (51.3%) had bowel malignancy, diverticular perforation in 19.3%. 21 patients (14%) mentioned change into their self-esteem following the surgery, 14% patients reported decline in their sexual life.

Conclusions

Pre & postoperative assessments should be carried out in detail with the patient to help them understand the implications of having a “stoma”. Stoma nurse involvement helps the patient to accept the changes to their life after the surgery. Psychological &sexual consultation helps in improving patient’s response to the challenge it may impose.

318 Management of Incidental Pancreatic Cysts –Are We Adhering to Guidelines?

Background

The majority of pancreatic cysts (PC) are incidentally diagnosed. Most NHS Trusts do not have pathways to manage them. We reviewed the management of incidental PC and adherence to guidelines.

Method

Data was collected across three hospitals in our Trust between January 2018-January 2019 when there were no guidelines. Reaudit was performed between July 2019-February 2020 following the introduction of trust guidelines that recommend all PC be discussed in MDT meetings.

Results

The first audit identified 79 patients and 28 in the second. 53% (42) and 64% (18) patients were referred to HPB/GI MDT during the two periods. There was an 11% increase in MDT referrals, however, 35.71% of patients were still not referred. During the initial audit, 62 % (23/37) of patients in the Non-MDT group had no surveillance scans, potentially missing high-risk patients and 38% of patients (14/37) still underwent surveillance scans from non-GI specialists which could be unnecessary. 44% of patients underwent surveillance following MDT in the second period as compared to 83% prior to guidelines (p = 0.002).

Conclusions

Robust guidelines for incidental PC identify high risk cysts that warrant future surveillance/treatment and avoid unnecessary scans releasing radiology capacity.MDT referral ensures malignant transformations are identified early and reduce morbidity and mortality.

950 Experience of Inguinal Mesh Hernioplasty Under Local Anaesthesia: A 3-Year Experience in A Teaching Hospital

Objective

To prove Inguinal mesh hernioplasty under L/A is safe and acceptable. Helps with post-operative pain and enables rapid recovery as a day case.

Method

All patients who underwent inguinal hernia repair under local anaesthesia were retrospectively analysed in our hospital between July 2014- July 2017. Clinical judgement was used for inclusion and exclusion parameters.

Results

From July 2014- July 2017, 260 patients were included in study who underwent Inguinal mesh hernioplasty under L/A. ASA grade for all patients ranged between I-III. The mean age was 37 (20-65). Intraoperatively (9.1) 3.5% patients had problems such as pain, hypotension or sweating. About (86.3%) 224 patients were discharged home the same day and remaining stayed overnight for less than 24 hours. Hematoma was seen in 5 (1.92%) patients, Urinary retention in 2 (0.7%) patients, Wound infection seen in 24(9.2%) patients, Readmission in 10 (3.8%) patients. Chronic groin pain was seen in 10 (3.9%) patients and no recurrence on 6 months follow up.

Conclusions

Our results showed that this procedure is feasible under L/A and can be performed safely. It showed satisfactory acceptance by the operating surgeon and patient, without significant perioperative issues. It is reliable and showed shorter hospital stay.

975 Outcome of Low Verus Standard Pressure Pneumoperitoneum in Laparoscopic Cholecystectomy: A Randomized Trial

Introduction

Recent studies have shown that patients may experience considerable pain after laparoscopic cholecystectomy as well. Hence, this study was done to compare results on post op pain with low pressure pneumoperitoneum compared with standard pneumoperitoneum.

Method

100 patients were selected for study and equally divided in two groups randomized into Low pressure (n = 50) and Standard pressure (n = 50). Operative time (min), postoperative pain (VAS) and frequency of Shoulder Tip Pain was noted in both groups

Results

A total of 100 patients were enrolled for this study. Patients were divided into two groups i.e. Group-A (Standard pressure) and Group-B (Low pressure). In group-A, there were 35(70%) males and 15(30%) females, while in group-B, there were 41(82%) males and 9(18%) females. Mean age of group-A patients was 42.0±7.0 years and 44.5±8.1 years in group-B. In group-A, 18(36%) patients had shoulder tip pain, while 4(8%) patients had had shoulder tip pain in group-B patients with a p-value of 0.001, which is statistically significant.

Conclusions

Laparoscopic cholecystectomy using low pressure pneumoperitoneum is feasible and results in less post-operative shoulder tip pain.

957 Comparison of Inguinodynia In Patients Undergoing Prophylactic Ilioinguinal Neurectomy vs No Neurectomy In Lichtenstein Mesh Hernioplasty

Objective

The objective of this study is to compare the frequency of inguinodynia in ilioinguinal neurectomy VS no neurectomy in patients undergoing Lichtenstein mesh hernioplasty.

Method

200 male patients with unilateral, primary, reducible inguinal hernia were randomly distributed in to two groups by using lottery method to undergo Lichtenstein’s hernia repair i.e., with and without ilioinguinal neurectomy. All the operation were carried out under local anesthesia. Pain score was calculated using the VAS system at 3rd month and inguinodynia was labelled if it is more than 1 on VAS scale.

Results

200 male patients with mean age of 53.25 ± 6.768 were included. 42 (21%) had Inguinodynia after surgery. When we cross tabulated both groups with inguinodynia, results came up significant (p = 0.001). In neurectomy group 10 patients had inguinodynia while in no neurectomy group, 32 patients were having Inguinodynia. There was no effect of malnutrition on outcome. Younger age group benefitted more from procedure.

Conclusions

It is concluded that there is difference in frequency of inguinodynia in ilioinguinal neurectomy versus no neurectomy in patients undergoing Lichtenstein hernia repair. Patients with ilioinguinal neurectomy had reduced incidence of inguinodynia.

P9: MANAGEMENT OF ESOPHAGEAL FOOD BOLUS OBSTRUCTION AT A UNIVERSITY TEACHING HOSPITAL – A RETROSPECTIVE ANALYSIS

Introduction

Despite the fact that esophageal food bolus obstruction is a common surgical problem, there are no clear guidelines on its management. Medical treatment with Buscopan and Glucagon is mostly in-effective, requiring a therapeutic Oesophago-Gastro-Duodenoscopy (OGD).

Method

All consecutive cases of food bolus obstructions (FBO) presenting to the Emergency Department (ED) for 18 month period between 01/01/2018 and 30/06/2019 were retrospectively reviewed.

Result

A total of 30 patients were admitted with food bolus obstruction via ED (1.67 per month). Females (67%) constituted most of these patients. Average age was 55 with range of 19-83. 84% of patients presented with Dysphagia, while Odynophagia (10%) and chest pain (6%) were other presenting symptoms. Average duration of symptoms was 17 hours (Range 2 – 48 hours). 44% of patients had OGD done under sedation while others (56%) had under General Anaesthesia (GA). In 70% of cases, food bolus was pushed into stomach, while it was retrieved out in 20%. In 10%, it had already spontaneously passed in stomach on OGD. The etiology of FBO was inflammatory in 60% cases, while an esophageal stricture was seen in 10% only. In 30% cases no cause of FBO was identified. Post-OGD length of stay was on average 1.15 days (range 12 hours – 7 days). 2 patients had aspiration pneumonia prolonging their hospital stay, there was no esophageal perforation or mortality.

Conclusion

Esophageal food bolus obstruction is a common surgical problem, OGD under GA is a safe recommended procedure, which often picks up an underlying pathology.

Take-home message

Esophageal food bolus obstruction is a common surgical problem, OGD under GA is a safe recommended procedure, which often picks up an underlying pathology.

Effect of Post-Isometric Relaxation and Laser on Upper Trapezius Trigger Point Pain in Patients with Mechanical Neck Pain

Objective

The current study aimed to determine the effectiveness of post-isometric relaxation and LASER treatment in minimizing pain and increasing neck range of motion and function in people with upper Trapezius trigger point pain.

Methods

A total of 45 participants with upper Trapezius trigger point pain were studied. All the participants were randomly assigned into three equal groups (post-isometric relaxation, LASER, and Control) to receive the respective treatments for 1 week. The pressure threshold meter was used to assess the pain-pressure sensitivity of myofascial trigger point pain. Pain intensity and cervical range of motion were measured using the visual analogue scale and cervical goniometry, respectively. The neck disability index was used to assess neck function.

Results

The results of within group analysis indicate significant changes in all the outcomes in three groups (All groups, P = 0.001) except an insignificant improvement of pain pressure threshold in the control group (P = 0.069). Additionally, there were significant differences noted among three groups on pain-pressure threshold and visual analogue scale scores at posttest day 1, day 5, and day 12 (all P = 0.001). However, there was non-significant improvements of neck disability index and side flexion on both sides noted at all timelines except (all P > 0.05), a significant improvement at posttest day 5 (P = 0.015) among three groups.

Conclusions

Both PIR and LASER treatment have been effective in reducing pain-pressure threshold and pain intensity in the management of muscle trigger point pain. Long-term studies are warranted to further validate the effectiveness of these modalities in the management of upper Trapezius trigger point pain.
