Abstract:
Background: The Colorectal 2-week wait (2WW) pathway is overwhelmed. qFiT has been added to the pathway, however cancer detection rate remains low ~5%. Using a novel rectal mucus sampling device (OricolTM) we hypothesized that shed genetic material could be retrieved from rectal mucus using OricolTM, potentially forming an accurate triage tool for colonoscopy or other investigation (Oricol EGI-02 Study). Method(s): The OricolTM device was used in symptomatic patients recruited from 4 NHS Trusts. DNA from FFPE-histology blocks was compared to the pre-operative OricolTM rectal mucus specimen. Using targeted next generation sequencing (NGS) incorporating error suppression technology, including unique molecular indexes (UMI's) and dual indexes (UDI's) for removal of PCR/sequencing errors/index hopping events, we assessed the single nucleotide polymorphisms (SNPs) present in 50 known CRC genes across both samples. Current recruitment to the Oricol-EGI- 02 Study is 586/600. 35 paired samples and 35 Oricol samples from normal 2WW colonoscopies were evaluated. Result(s): There were no statistical differences between tumour associated SNP burden in the FFPE-blocks and the rectal mucus sample from CRC patients. Tumour associated SNP burden in the paired cancer samples was significantly higher compared to the normal group (p < 0.001). Identical SNPs were identified in both tumour and paired Oricol samples. Conclusion(s): This result confirms the hypothesis that shedding of DNA from colorectal cancers (caecum to rectum) can be detected in rectal mucus using OricolTM. Sampling rectal mucus could be used to accurately detect CRC in unprepared patients, dramatically reducing the number of normal colonoscopies which currently overwhelm the 2WW pathway.

Abstract:
Objectives The Junior MARSIPAN guidelines were created to improve the medical care of paediatric patients with severe anorexia nervosa. This audit aims to evaluate the care provided by a general paediatric ward compared to the recommendations outlined in the MARSIPAN guidelines and the completion of risk assessments. Methods Retrospective analysis of patient notes was conducted on the most recent admission to the general paediatric ward of 10 patients with anorexia nervosa within the last 24 months. The documentation of their care was audited against a pre-made proforma based on the MARSIPAN guidelines and the MARSIPAN risk assessment. Medical notes and a nursing care pathway document were reviewed. The initial blood tests, refeeding blood and nursing care was also assessed. The inclusion criteria for this audit was any patient under the age of 18-years-old admitted in the last 24 months to the general paediatric ward. Any patients currently admitted or without a complete set of admission and inpatient medical notes were excluded. Results 10 patients were included and a total of 434 bed days were assessed. Our results show variability in compliance with the MARSIPAN guidelines, in terms of the initial admission and the care received. On admission, 70% of the patients were reviewed by a consultant, 30% had a full MARSIPAN risk assessment and 40% had a percentage median BMI calculated. Important investigations were inconsistently completed, such as an ECG with a recorded QTc length (70%), sitting and standing blood pressure (20%), dehydration assessment (30%), and SUSS stand-squat and sit-up test (20%). Common initial blood tests such as Full Blood Count, Bone Profile and Liver Function Tests were completed for all patients, however many of the other important investigations were incomplete; for example Folate and B12 (40%), amylase (20%) and creatinine kinase (0%). 80% of the patients received daily biochemical blood tests to screen for refeeding syndrome in their first week in hospital; 100% of the refeeding blood tests included U&Es, magnesium, and phosphate levels. During their stay, 80% of patients had input from a dietitian and 100% had input from either CAMHS or a specialist eating disorder service. 20% of patients had daily consultant reviews and 30% of patients had a MARSIPAN risk assessment done during their admission, with only 10% having regular risk assessments. All patients received thiamine and vitamin supplementation. Nursing care was adherent to guidelines with 4-hourly vitals, enforced bed-rest, and supervised mealtimes for 100% of patients. 70% of patients had 4-hourly blood glucose measurements. Conclusions The medical care documentation assessed in this audit was not compliant with MARSIPAN guidelines but nursing care was. The findings in this audit, along with national audits, suggest sub-optimal care for inpatient admissions with anorexia nervosa. The excellent nursing results demonstrates the introduction of the nursing pathway document makes a significant difference. We recommend a joint medical and nursing pathway document for admission including weekly medical reviews should be implemented and re-audited to reassess the documentation and adherence to guidelines, especially in light of the new MEED (Medical emergencies in eating disorders -CR233) guidelines.

Abstract:
Purpose: Diverting loop-ostomies are sometimes formed in patients undergoing resection for rectal cancer with primary anastomosis. Timing to reversal is commonly reported between 3-6 months of original surgery, with longstanding issues of delays secondary to low-surgical prioritisation. Our retrospective study over a 5-year period aims to understand the effect on timing to reversal of the COVID-19 pandemic. Method(s): All patients undergoing resection for rectal cancer were identified from the Hospital Episode Statistics data between 01.01.2018 and 01.07.2021. Data was then cross-referenced with patients undergoing reversal surgery. Demographics, time to surgery, length of stay and post-operative morbidity data were collected. <br/>Result(s): There were 262 anterior resections performed. 192 patients had resection with primary anastomosis (PA): 85 had formation of loop ileostomy, 23 formation of loop colostomy. Results before March 2020: 65 resections with PA and ileostomy. 34 (52.3%) reversed with median time to reversal of 266 days, (range 98-1015). 16 resections with PA and colostomy. 7 reversed (44%), median time to reversal 476 days (range 104-768). Results after March 2020: 20 resections with PA and loop-ileostomy. 3 have been reversed (15%), with median time to reversal of 211 days, (range 103-449). 7 resections with PA and colostomy, none reversed. Showing reduction in overall stoma-reversal in the post pandemic period (p = 0.000297). Conclusion(s): We will experience ongoing conflicts with prioritisation of caseloads as the ongoing effects of COVID continue. This is the time for novel solutions to a building crisis, such as ring-fenced lists or same-day surgery with ambulatory follow-up.

Abstract:
Purpose: For decades there has been very little change in practice in the surgical management of perforated diverticulitis. Reluctance to risk anastomotic leak persists despite increasing recognition that primary anastomosis (PA) should be considered in selected patients as an alternative to Hartmanns Procedure (HP). We retrospectively studied our outcomes for patients undergoing resectional surgery for diverticulitis. Method(s): All patients undergoing emergency resectional surgery for perforated diverticulitis between March 2015 and Jan 2021 were identified from the Hospital Episode Statistics (HES) data. Demographics were collected and the patient groups were case matched for age and Charleson Comorbidity Index (CCI), Computed Tomography (CT) appearance and intraoperative contamination data. Result(s): 105 patients were included. 15 patients had PA (without diversion) and 90 HP. In the PA cohort were 10 males, median age 52 (range 27-76). There were no anastomotic leaks. 30-day morbidities were superficial wound dehiscence (1) and early incisional hernia (1). Median post-operative stay was 9 days (range 5-25). HP control group (age below 76, CCI 10 and below, Hinchey 1-3). 58 patients, 26 males, median age 60.5 (range 30-76). Median post-operative stay was 10.5 days (range 5-227). 2 patients required re-operation. 5 patients developed wound infections. At the time of the study 18 patients have undergone reversal, 6 are on waiting-list. There was a single 30-day mortality (post-discharge). Conclusion(s): PA in selected patients is not only safe, but has lower morbidity than HP. We should be challenging the status quo and offering our patients appropriate surgery on an individualised basis.

Abstract:
Background: Faecal calprotectin testing is recommended by the National Institute for Health and Care Excellence (NICE) to distinguish between inflammatory bowel disease (IBD) and irritable bowel syndrome (IBS) after cancer exclusion. Many patients do not produce faecal samples as requested and therefore a direct collection technique may have a role in IBD diagnosis or monitoring. We compared the performance of faecal and rectal mucus calprotectin collected with the OriColTM sampling device Methods: Sixty-six patients with confirmed or suspected IBD were recruited in the Oricol-EGI- 01 Study. OriColTM and matched stool samples were collected and processed following standard operating procedures. Calprotectin concentrations were measured using IDK Calprotectin and fCAL assays Results: Calprotectin was detectable in the OriColTM samples with good discrimination across the calprotectin assays and discernible correlation to corresponding faecal calprotectin concentrations Using thresholds determined for rectal mucus calprotectin (calculated by linear regression), the percentage agreement between calprotectin concentrations in stool and rectal mucus for patients with faecal calprotectin >=50 mug/g was between 68% and 91% with a percentage agreement at <50 mug/g between 40% and 71% with IDK Calprotectin and fCAL assays respectively. Good agreement was observed for IBD patients with the results being above the threshold for both faecal and rectal mucus calprotectin with 93% and 86% for IDK Calprotectin and fCAL assays respectively Conclusion(s): The OriColTM Calprotectin Kit was successfully used to collect rectal mucus and measure calprotectin concentrations with positive correlation to corresponding faecal calprotectin and is potentially a new and acceptable modality in IBD patients.

Abstract:Background: Elevated body mass index (BMI) in breast cancer survivors (BCS) is associated with cancer recurrence and poorer treatment response. Guidelines recommend 5%-10% weight loss for overweight or obese BCS.Objectives: To assess effectiveness of lifestyle interventions for female BCS on weight loss, BMI, body composition, health-related quality of life (HRQoL), physical functioning, psychosocial measures, biomarkers.Design: Systematic review of reviews and meta-analyses.Setting: All clinical settings.Participants: Adult female BCS (active treatment or post-treatment).Methods: Medline, Embase, CINAHL, PsycINFO, Cochrane Library (including Database of Abstracts of Reviews of Effects) were searched for systematic reviews published in English between 1990 and 2022, with weight, BMI or body fat as primary outcome. Narrative reviews, editorials, letters, conference abstracts were excluded. Review quality was assessed using the Joanna Briggs Institute quality assessment tool.Results: 17 reviews were included. Twelve reported significant reductions in one or more anthropometric outcomes: weight -1.36 kg (95% CI:-2.51 to -0.21) to -3.8 kg (95% CI: -5.6 to -1.9); BMI -0.89 kg/m 2 (95% CI: -0.15 to -0.28) to -3.59 kg/m 2 (95% CI: -6.29 to 0.89) or body fat -1.6% (95% CI: -2.31 to -0.88) to -2.6% (95% CI not reported). Significant reductions in two or more anthropometric outcomes were reported in 7/12 reviews, with effective interventions comprising aerobic exercise/aerobic exercise plus resistance training (n=5), or diet and exercise with or without counselling (n=2). Significant improvements were also reported for HRQoL (8/11 reviews), mental health (4/7) and physical functioning (2/3). Group interventions comprising aerobic exercise or aerobic exercise plus resistance training were most likely to improve outcomes.Conclusions: Lifestyle interventions can significantly improve outcomes for BCS. Multimodal interventions are likely to have the greatest impact in reducing weight, BMI and body fat. Further research must define the optimal combination, intensity and duration of effective interventions.

Abstract:Introduction: Use of patient specific instrumentation (PSI) for performing total knee arthroplasty (TKA) has been shown to improve component positioning but there is dearth of evidence regarding clinical outcomes. The aim of our study was to report patient satisfaction and functional outcome scores of patients who underwent PSI TKAs at minimum 5 year follow up.Methods: This is a retrospective study of a prospectively collected data of patients who underwent PSI TKAs between January 2012 and October 2015 under a single surgeon. Patient Reported Outcome Measures (PROMs), patient satisfaction questionnaires, surgeon directed 3D planning changes and intra-operative changes were collected and analysed.Results: The cohort included 298 consecutive PSI TKAs performed on 249 patients at a mean age of 71 years (range: 49-93 years). On an average 4 changes were made for each knee during 3D planning compared to preliminary plan. Intra-operative implant size change was required only in 3% (10 knees). The PROM scores were collected at a mean follow-up period of 6.8 years (range: 5.0-8.6 years) for 224 knees. Oxford Knee Score improved from median pre-operative score of 18 (IQR: 13-24) to median post-operative score of 44 (IQR: 40-47) with a median gain of 23 (IQR: 16-30). The median modified Forgotten Joint Score was 87.5 (IQR: 54.4-98.1). For the Beverland questionnaire, 75% (n = 166) reported being "Very Happy" and only 4% (n = 9/222) were 'Never Happy'.Conclusion: Excellent patient satisfaction and functional scores at mid-term can be achieve d using PSI technique to perform TKA with careful surgeon directed pre-operative planning.

Unilateral Testicular Tuberculosis: An Extra-Pulmonary Manifestation (2021)

Posted on by

Type of publication:Journal article

Citation:Cureus, 2021 Oct 19; Vol. 13 (10), pp. e18896

Abstract:The pathogenicity of Mycobacterium tuberculosis (M. tuberculosis) causes it to most commonly manifest within the respiratory system (pulmonary tuberculosis); however, 15% of cases undergo extra-pulmonary spread to various organs. Genitourinary tuberculosis (GUTB) is a rare form of tuberculosis infection which has a propensity to affect the genitourinary tract, primarily affecting the kidneys, epididymis, seminal vesicles and prostate; however, 0.5% of cases result in infection of the testicles. This may present unilaterally or bilaterally with varying atypical presentations, thus misleading physicians in diagnosis. We present a case in a 48-year-old patient admitted to the surgical assessment unit in our hospital presenting with a unilateral painful testicular lesion and scrotal changes. He was admitted nine weeks prior for unexplainable constitutional symptoms however presented again whilst awaiting follow up in an outpatient clinic. Ultrasound guidance and fine-needle aspiration & culture (FNAC) of the lesion resulted in a positive diagnosis for M. tuberculosis. He underwent anti-tuberculous chemotherapy treatment for six months as per clinical guidance with adequate clinical response.
