Abstract:

Background: Although mucus plugging occluding medium to large sized airways in COPD is associated with increased long term all-cause mortality, acute exacerbations require further investigation, particularly where, despite reducing morbidity and improving quality of life, long-term use of mucolytics remains controversial. Objectives were (1) to quantify chest CT evidence of mucus plugging, (2) relate findings to mucolytics, and (3) investigate mucus plugging association with short term mortality.

Method(s): Retrospective review of 100 patients admitted with exacerbation of COPD (105 admissions).comparative analysis by chi square (x2) and logistic regression, significant p<.05.

Result(s): Mean (SD, range) age was 74.7 (10.5, 41-97) years with 54% male; mean FEV1/FVC 55% with FEV1 1.2(0.59, 0.4-3.6) litres at 49% predicted. 23 were on long term oxygen (LTOT). Mean stay was 6.3 (1-41) days. 24 died in the first 6 months. Where a historical or admission chest CT was available (n=82), 12 (15%) had mucus plugging with mucolytics prescribed to 6 (50%) compared to 32/70 (46%) without plugging (x2 0.057, NS). 9/56 (16%) with mucus plugging vs 3/26 (12%) without (x2 0.2921, NS) had emphysema and 3/13 (23%) vs 9/69 (13%) without (x2 1.016, NS) bronchiectasis. Regression investigating mortality at 6 months showed adverse outcomes for male sex, lower FEV1, and LTOT.

Conclusion(s): 15% with acute COPD admissions have current or historical evidence of mucus plugging. Mucolytics are prescribed for 45% irrespective of prior CT radiology. Mortality (24%) at 6 months is high but not shown related to mucus plugging or reduced by mucolytics.

Abstract:

Background: Economic data inform public health measures; a co-ordinated approach to TB contact tracing, guided by Public Health England (PHE), was undertaken assessing a non English speaking Eastern European immigrant population seasonally employed at an agricultural farm and we (1) report direct costs, (2) identify cultural issues and risks employing such a population Methods: After an initial pilot study of work-based contacts of an index case, contact lists incorporating workforce in every shift pattern back-dated two years to his UK entry were identified. Direct costs included T-spot testing (Oxford Immunotec) and translators (Romanian, Polish, Lithuanian, Italian) along with secondary care charges at tariff with uniform cross-charge among providers. TB drug costs (managing latent or disease) were from the British National Formulary.
Result(s): 258/331 (78%) workers took up testing. 80 (31%) were then referred for contact screening; of these, 47 had latent and 3 active disease. 16 defaulted, 5 declined, 4 were pregnant, and 5 lost moved elsewhere. Most had no registered General Practitioner and no pre-employment health check, BCG or radiology. Anecdotally, several returned to their parent countries for healthcare advice despite measures to overcome language barriers. Main direct costs (51,497-52) equated to 199-60/person screening and 1029-95/person treated for either latent or TB disease.
Conclusion(s): Language and cultural barriers are challenges to TB screening/contact tracing. Direct costs are 200 (UK pound sterling = 1.17 Euro) per patient screened and five times this amount treating latent or active disease.

Pleural infection presentation and timeline of events: Real-world data from a tertiary hospital in the UK.

Abstract:

Background: Pleural infection remains a significant burden on mortality and morbidity in the Western world even with the advancement of clinical management.

Objective(s): This paper aims to study the clinical course of empyema thoracic patients managed in a tertiary hospital in the UK.

Method(s): We did a retrospective observational study of the hospital's electronic records of patients who were diagnosed and managed for empyema thoracic from January 2021 to December 2022.

Result(s): The total cohort was 104 empyema thoracic patients. The mean age was 60. The affected males were almost double than females (68 vs 36). We did a retrospective RAPID score of our cohort. The RAPID score could not be calculated for 35 patients due to the unavailability of pleural fluid data. High inpatient mortality (23%) was observed in the medium- risk (RAPID score 3-4) group and high 3-month mortality (25%) was observed in the high-risk (RAPID score 5-7) group. The majority of the patients were managed conservatively. No difference was noticed in the median length of hospital stay (11d) in all the risk groups. A high rate of (37%) surgical management was observed in the low-risk (RAPID score 0-2) group.

Conclusion(s): Our cohort's data comply with the predicted mortality risk of the RAPID score. We emphasize that RAPID score calculation can be a significant tool in the management of empyema thoracic patients.

Abstract:

Intro: Active smoking plays a crucial role in cardiovascular disease. We looked at the rate of attendance to primary and secondary care amongst current smokers with increased QRISK and CAT scores.

Methodology: Data were drawn retrospectively from electronic medical records from a large tertiary care hospital covering Staffordshire region over a one year period 2019-2020. Data was extracted from lung cancer screening cohort.

Result(s): The data comprised of 1232 patients (516 female, 716 male). Of these, 566 were exsmokers and 666 current smokers. Average age was 62 years. Analysis was done using ANOVA. This confirms that current heavy smokers, had an increased QRISK score >10 (p value <0.05, 95% CI 0.00 to 0.02). 1 year mortality in this group was 2.8%. Heavy smokers were not at an increased risk of attending primary care (p value 0.862) or at increased risk of unplanned secondary care admissions (p value 0.09) as compared to light smokers. Median length of hospital stay was 8 (0 – 16) bed days in heavy smokers as compared to 4 bed days (0 – 8) in ex smokers. Female ex smokers had fewer hospital attendances as compared to female current smokers, male current and ex smokers (p value <0.05, tests statistic 4.207). A high CAT score was documented as >20 denoting impact of COPD on patient's life. It was not identified as a predictor of increased attendance to primary or secondary care.

Conclusion(s): Heavy smokers have a higher economic burden on acute secondary care on account of higher number of bed days. Early smoking cessation intervention may help reduce attendance into secondary care.

Abstract:

Background: Prognosis with pleural mesothelioma depends not only on histological typing but also distribution of metastatic disease (including stage 4 with distant spread) and performance status. Analysing all patients presenting at his hospital Trust over 10 years, this work (1) reports the pattern of metastatic disease and, accepting the complex multi-modality approach to treatment, (2) relates findings to survival.

Method(s): Retrospective computer based analysis conferring with oncology and radiology records. 169 patients (84% male) with mean (range) age 74.4 (44 to 93) years.

Result(s): Respectively, performance status was 0 (16%), 1 (34%), 2 (26%), 3 (18%) and 4 (1%). 70% only had thoracic disease (pleural, pericardial, mediastinal, pulmonary) and 30% extrathoracic extension (chest wall/extrapleural, diaphragmatic, peritoneal/omental/ascites), liver/spleen/adrenal, spine and bone, and other (including brain and brachial plexus). Overall, 94% were diagnosed on tissue samples; where histology was clarified, 63% with epithelioid survived longer at (mean) 15 months compared to the 37% with 12.6 months for sarcomatoid or biphasic typing. Although active treatments often involved the complexity of multimodality, 34% had best supported care (usually worse performance status).

Conclusion(s): Findings highlight the aggressive nature of pleural mesothelioma confirming at least 30% had extrathoracic metastases and marginally improved outcomes with epithelioid histology.

Abstract:

Background: Previous examination of data from the United Kingdom indicates no apparent ethnic disparity in the treatment of patients hospitalised with non-ST-segment elevation myocardial infarction (NSTEMI). However, it remains uncertain whether this lack of disparity results in similar long-term survival outcomes among ethnic minority groups, particularly those with multiple underlying risk factors for coronary artery disease, when compared to White patients.

Purpose(s): To assess the impact of quality of care on short-term and long-term survival among NSTEMI patients while examining disparities based on ethnicity.

Method(s): We analysed records of 252,964 individuals diagnosed with NSTEMI from the Myocardial Ischaemia National Audit Project database spanning 2005 to 2019, alongside Office of National Statistics data for mortality. Among them, 233,158 were identified as White patients, while 19,806 were categorised as belonging to ethnic minority groups (Asian, Black, and mixed ethnicity). Propensity score matching was used to compare average treatment effects between cohorts while survival was compared using Cox regression model.

Result(s): Ethnic minorities were younger (median age in years) (66 vs. 73, P < 0.001), predominantly male (70% vs. 63%, P < 0.001), and exhibited a higher prevalence of cardiovascular risk factors such as diabetes (52% vs. 24%, P < 0.001), hypertension (67% vs. 54%, P < 0.001), hypercholesterolemia (49% vs. 34%, P < 0.001), and chronic renal dysfunction (13% vs. 8%, P < 0.001). Ethnic minorities more frequently underwent invasive coronary angiography (80% vs. 68%, P < 0.001), percutaneous coronary intervention (53% vs. 44%, P < 0.001), and coronary artery bypass grafting (5% vs. 4%, P < 0.001). After conducting propensity score matching, both cohorts had no significant differences in in-hospital all-cause mortality [odds ratio (OR) 1.13, confidence interval (CI) 0.89 – 1.43; P = 0.268], cardiac mortality (OR 1.20, CI 0.89 – 1.54; P = 0.209), one-year mortality (OR 1.01, CI 0.89 – 1.13; P = 0.893) and major adverse cardiovascular events (OR 1.21, CI 0.95 – 1.48; P = 0.108). However, upon conducting a five-year survival analysis, ethnic minorities had better survival rates than their White counterparts (Hazard ratio (HR) 0.89, CI 0.86-0.92; P < 0.001).

Conclusion(s): Despite ethnic minorities being at a higher risk for coronary artery disease, our findings indicate that they experience better five-year survival rates than White patients. This suggests equitable access to care and potentially a more aggressive treatment approach in this relatively young patient cohort.

Abstract:

Background: The characteristics and outcomes of patients treated with vedolizumab in routine healthcare settings have not been widely evaluated in the UK. Method(s): Prospective, multicentre observational study of 364 patients started on vedolizumab in UK practice from January 2017 until February 2019 using the UK IBD Registry clinical web-based tool. For the present analysis, the primary outcome was drug survival (persistence) at 1-year, defined as attendance for infusion >=48 weeks after the first dose. Secondary outcomes were: Clinical remission (CR, based on partial Mayo score [<=1] or Harvey Bradshaw index [<=4]), physician global assessment (PGA), IBD-Control Questionnaire (IBD-Control-8, IBD-Control-VAS and individual item scores), laboratory parameters and adverse events. Result(s): Age (mean): 44 yrs; Males: 48%; IBD duration (mean): 6 yrs; Prev. resection: 18%; Steroids at baseline: 39%; Outcomes are summarized in Table 1. 37% of CD patients were assessed as being in clinical remission at baseline. Overall, 210 (58%) continued treatment beyond 48 weeks. At 1 year, 67.1% and 52.3% of CD and UC patients were in clinical remission with a clear improvement in QoL as assessed by IBD-Control -8. There were significant improvements across each IBD-Control-8 domain, including fatigue, with few patients considering switching treatment at that point (Figure 1). Conclusion(s): Vedolizumab was effective in clinical practice with 58% of patients remaining on treatment at one-year. Baseline status differed significantly from those recruited into RCTs. Patient reported outcomes demonstrated significant and meaningful improvements across physical, psychological, social and treatment domains.

Abstract:

Clinical assessment: 70-year-old lady presents with one-day history of dyspnoea, chest and abdominal pain. She was recently discharged following a three-week hospital admission with fall related traumatic rib fractures and hospital acquired pneumonia. Her abdomen was soft and non-tender. CT scan with oral and IV contrast demonstrates pneumomediastinum and pneumoperitoneum with connection at diaphragmatic crura. Management: Patient was managed conservatively however two days after admission her CRP climbed to 150 and clinical suspicion remained high. Repeat CT scan over the weekend demonstrated increase in the pneumoperitoneum and decrease in the pneumomediastinum with a collection around sigmoid colon. Trainee raised concern to consultant and a laparotomy was done. Operative findings showed perforated sigmoid colon with faeculent peritonitis of unclear cause. Hartmann's procedure was done and patient continued post recovery in ITU. Discussion(s): This case demonstrates the complex varying presentations of our elderly co-morbid population. The presence of air in thoracic and abdominal cavities with unknown cause weeks after the fall was suspicious. Hence, the team communicated well from top-down and likewise from weekday to weekend. Low threshold for escalation and high index of suspicion enabled a re-scan which proved to be life-saving for this patient. Identifying complicated cases where errors can occur is a critical first step. Clear communication among staff, accurate documentation and addressing the patient concerns enabled the surgical team to navigate the complex disease process and ensure safe patient care.

Abstract:

Background: Metformin is a widely used, well tolerated anti-diabetic agent. Several studies suggest metformin has anti-cancer activity in different malignancies, including prostate cancer. We hypothesised that metformin also reduces the development of ADT-induced metabolic adverse effects, possibly improving OS via these mechanisms. Method(s): Non-diabetic pts with mHSPC were randomly allocated 1:1 to standard of care (SOC) or SOC+metformin within STAMPEDE. SOC included ADT +/- radiotherapy +/- docetaxel +/- androgen receptor pathway inhibitor (ARPI). The primary outcome was OS. Target hazard ratio (HR) 0.8 (92% power, 2.5% 1-sided significance). 7 subgroup analyses were pre-specified but not pre-powered. Result(s): 1874 pts with mHSPC were randomised Sep2016-Mar2023. Arms were well balanced: median age 69 years, IQR 63-73; median PSA 84ng/ml, IQR 24-352; de novo 1758 (94%) vs relapsed 116 (6%). Planned SOC included 82% Docetaxel and 3% ARPI. After a median follow-up of 60 months, the HR for OS between arms was 0.91 (p=0.148; 95% CI 0.80-1.03). The median (95%CI) OS was 63 (58-69) and 69 (63-73) months in the SOC and SOC+metformin arms respectively. In patients with high versus low volume disease (CHAARTED def), HR was 0.79 (p=0.006; 0.66-0.93) and 1.0 (p=0.992; 0.79-1.26) respectively. The interaction p-value = 0.086. For progression-free survival: Overall HR was 0.92 (p=0.164; 0.81-1.04) with HRs of 0.76 (p=0.001; 0.64-0.89) and 1.10 (p=0.401; 0.88-1.37) in the high and low volume subgroups respectively, interaction p-value = 0.006. Metabolic parameters that improved significantly with metformin included reduced weight gain, fasting glucose, HbA1c and total and LDL cholesterol. Fewer patients developed a metabolic syndrome. Adverse events (AE) >=grade 3 were reported in 52% and 57% in the SOC and SOC+metformin arms, respectively; Gastrointestinal AEs increased with metformin. Conclusion(s): Metformin does not improve survival in unselected metastati
