'I Do It All Alone': The Burdens and Benefits of Being Diagnosed With, and Treated for, Colorectal Cancer During the Covid-19 Pandemic.

INTRODUCTION: The Covid-19 pandemic dramatically altered the way cancer care services were accessed and delivered, including for colorectal cancer (CRC). In the United Kingdom, patients were discouraged from presenting in primary care, many consultations took place remotely, investigative procedures and screening programmes were temporarily suspended, and fewer operations and treatments were delivered. People had to face the practical consequences of having cancer during a pandemic and navigate never before seen pathways, often alone. We examined the experience of being diagnosed and treated for CRC during the pandemic, and the implications of this on people's cancer journeys. METHODS: Semi-structured interviews were undertaken with people diagnosed with CRC during the Covid-19 pandemic (January 2020-May 2021), in the North East of England. An iterative topic guide was used during interviews, which took place remotely (telephone or Zoom), were audio recorded, pseudo-anonymised and transcribed. Initial transcripts were independently coded by two researchers, and a code 'bank' developed for application across transcripts. Development of themes and overarching analytical constructs was undertaken collaboratively by the research team. RESULTS: Interviews were conducted with 19 participants, analysed and four key themes identified: (1) The relative threats of Covid-19 and Cancer were not comparable, with cancer seen as posing a far greater risk than Covid-19; (2) Remote consultations were problematic, affecting patients' abilities to build rapport and trust with clinicians, assess nonverbal communication, and feel able to disclose, comprehend and retain information; (3) Stoma follow-up care was seen to be lacking, with long wait times for stoma reversal experienced by some; Finally, (4) Being alone during consultations negatively impacted some peoples' abilities to absorb information, and left them without the support of loved ones at an emotionally vulnerable time. However, some participants preferred being alone at certain points in their pathways, including receiving a diagnosis, and most frequently when receiving in-patient treatment. CONCLUSION: Being alone brought unexpected benefits, absolving people from undertaking emotions work for others, and instead focus on their recovery, however, remote consultations negatively impacted patients' experiences. This study highlights the complex benefits and burdens of pandemic-located cancer journeys, including how these shifted at different points across cancer pathways. PATIENT OR PUBLIC CONTRIBUTION: Lorraine Angell, a cancer survivor, has been central to this study from idea conception, contributing to: development of study focus and design; securing funding; production of patient-facing materials; development of interview topic guides; analysis and interpretation of data; and drafting of key findings and manuscripts.

Measuring quality of life in people living with and beyond cancer in the UK.

PURPOSE: The aim of this study was to identify the most appropriate measure of quality of life (QoL) for patients living with and beyond cancer. METHODS: One hundred eighty-two people attending cancer clinics in Central London at various stages post-treatment, completed a series of QoL measures: FACT-G, EORTC QLQ-C30 , IOCv2 (positive and negative subscales) and WEMWBS, a wellbeing measure. These measures were chosen as the commonest measures used in previous research. Correlation tests were used to assess the association between scales. Participants were also asked about pertinence and ease of completion. RESULTS: There was a significant positive correlation between the four domain scores of the two health-related QoL measures (.32 ≤ r ≤ .72, P < .001), and a significant large negative correlation between these and the negative IOCv2 subscale scores (- .39 ≤ r ≤ - .63, P < .001). There was a significant moderate positive correlation between positive IOCv2 subscale and WEMWBS scores (r = .35, P < .001). However, neither the FACT-G nor the EORTC showed any significant correlation with the positive IOCv2 subscale. Participants rated all measures similarly with regards to pertinence and ease of use. CONCLUSION: There was little to choose between FACT-G, EORTC, and the negative IOC scales, any of which may be used to measure QoL. However, the two IOCv2 subscales capture unique aspects of QoL compared to the other measures. The IOCv2 can be used to identify those cancer survivors who would benefit from interventions to improve their QoL and to target specific needs thereby providing more holistic and personalised care beyond cancer treatment.

Gut microbiota composition correlates with diet and health in the elderly.

Alterations in intestinal microbiota composition are associated with several chronic conditions, including obesity and inflammatory diseases. The microbiota of older people displays greater inter-individual variation than that of younger adults. Here we show that the faecal microbiota composition from 178 elderly subjects formed groups, correlating with residence location in the community, day-hospital, rehabilitation or in long-term residential care. However, clustering of subjects by diet separated them by the same residence location and microbiota groupings. The separation of microbiota composition significantly correlated with measures of frailty, co-morbidity, nutritional status, markers of inflammation and with metabolites in faecal water. The individual microbiota of people in long-stay care was significantly less diverse than that of community dwellers. Loss of community-associated microbiota correlated with increased frailty. Collectively, the data support a relationship between diet, microbiota and health status, and indicate a role for diet-driven microbiota alterations in varying rates of health decline upon ageing.

Impact of Variations in Test Method Parameters on In Vitro Activity of Surotomycin against Clostridium difficile and Surotomycin Quality Control Limits for Broth Microdilution and Agar Dilution Susceptibility Testing.

Test parameter variations were evaluated for their effects on surotomycin MICs. Calcium concentration was the only variable that influenced MICs; therefore, 50 µg/ml (standard for lipopeptide testing) is recommended. Quality control ranges for Clostridium difficile (0.12 to 1 µg/ml) and Eggerthella lenta (broth, 1 to 4 µg/ml; agar, 1 to 8 µg/ml) were approved by the Clinical and Laboratory Standards Institute based on these data.

Linezolid-resistant Staphylococcus aureus strain 1128105, the first known clinical isolate possessing the cfr multidrug resistance gene.

The Cfr methyltransferase confers resistance to six classes of drugs which target the peptidyl transferase center of the 50S ribosomal subunit, including some oxazolidinones, such as linezolid (LZD). The mobile cfr gene was identified in European veterinary isolates from the late 1990s, although the earliest report of a clinical cfr-positive strain was the 2005 Colombian methicillin-resistant Staphylococcus aureus (MRSA) isolate CM05. Here, through retrospective analysis of LZD(r) clinical strains from a U.S. surveillance program, we identified a cfr-positive MRSA isolate, 1128105, from January 2005, predating CM05 by 5 months. Molecular typing of 1128105 revealed a unique pulsed-field gel electrophoresis (PFGE) profile most similar to that of USA100, spa type t002, and multilocus sequence type 5 (ST5). In addition to cfr, LZD resistance in 1128105 is partially attributed to the presence of a single copy of the 23S rRNA gene mutation T2500A. Transformation of the ∼37-kb conjugative p1128105 cfr-bearing plasmid from 1128105 into S. aureus ATCC 29213 background strains was successful in recapitulating the Cfr antibiogram, as well as resistance to aminoglycosides and trimethoprim. A 7-kb cfr-containing region of p1128105 possessed sequence nearly identical to that found in the Chinese veterinary Proteus vulgaris isolate PV-01 and in U.S. clinical S. aureus isolate 1900, although the presence of IS431-like sequences is unique to p1128105. The cfr gene environment in this early clinical cfr-positive isolate has now been identified in Gram-positive and Gram-negative strains of clinical and veterinary origin and has been associated with multiple mobile elements, highlighting the versatility of this multidrug resistance gene and its potential for further dissemination.

Identification and characterization of linezolid-resistant cfr-positive Staphylococcus aureus USA300 isolates from a New York City medical center.

The cfr gene was identified in three linezolid-resistant USA300 methicillin-resistant Staphylococcus aureus (MRSA) isolates collected over a 3-day period at a New York City medical center in 2011 as part of a routine surveillance program. Each isolate possessed a plasmid containing a pSCFS3-like cfr gene environment. Transformation of the cfr-bearing plasmids into the S. aureus ATCC 29213 background recapitulated the expected Cfr antibiogram, including resistance to linezolid, tiamulin, clindamycin, and florfenicol and susceptibility to tedizolid.

People, places, systems and society:A qualitative exploration of socio-cultural factors in head and neck cancer survivorship.

PURPOSE: People living with head and neck cancer (HNC) often endure permanent and life changing adverse effects of treatment and reduced health-related quality of life. Study of post-traumatic growth (PTG), is gaining traction to understand why some people living with cancer have better psychosocial outcomes than others. Current theoretical models on PTG point to the importance of 'socio-cultural influences' but do not provide insight into how such socio-cultural factors influence survivorship outcomes. This research aimed to illuminate pathways to PTG following HNC by exploring socio-cultural factors in experiences of living with, and moving on from, HNC. METHOD: Semi-structured interviews with people living with HNC (up to 5 years post-treatment) on experiences of diagnosis, treatment and recovery. Qualitative framework analysis using the environmental factors codes from the International Classification of Functioning, Disability and Health (ICF) HNC core set. RESULTS: 20 people living with HNC were interviewed (11 male, 9 female; aged 46-83 years). Four inter-related themes described socio-cultural factors that influence (positively and/or negatively) the experience of living with HNC: (1) people and places; (2) healthcare systems and support services; (3) societal attitudes to cancer; (4) work and finances. CONCLUSION: Support from family, friends and healthcare professionals, as well as societal attitudes, financial and work security and personal experiences all appear to contribute to an individuals' ability to navigate the HNC experience. These findings could inform development of interventions targeting the socio-cultural factors in the lives of people living with HNC, particularly for those at risk for poorer psycho-social outcomes.

Patient experiences of Cytosponge: a qualitative study.

Objective: Cytosponge is a novel technology for oesophageal pathology diagnosis. Uses include diagnosis of Barrett's oesophagus and as a triage tool to prioritise upper gastrointestinal endoscopy. Patient experience is a key component of quality care. Previous work has developed endoscopy patient-reported experience measures. An appropriate tool to measure patient experience of Cytosponge is required. The aim of this work was to describe the patient experience of Cytosponge. Design/Method: Individuals aged 18 years or over, who had undergone Cytosponge from September 2020 to March 2021, were invited to participate in a semi-structured interview. Interviews were audio-recorded, transcribed verbatim and anonymised. Thematic analysis was undertaken. Themes were organised into two overarching areas relating to patient experiences and patient perceptions of the test. Results: 19 patients underwent interview (aged 37-80 years, 13 male). In terms of patient experiences of Cytosponge, five themes were identified: emotional reaction; expectations; environment and physical process; sensory experience; communication and information. All themes were present across all procedural phases, aside from sensory experience which was only present during the test. With regard to perception of the test, two major themes were identified: test novelty (encompassing patient awareness of the test and reaction to the new test) and trusting the test results. Conclusion: Patients must remain central to novel technologies such as Cytosponge. Measuring patient experience is essential to achieve that. This study demonstrates five major themes which describe the patient experience of this procedure. These have been used to adapt the Newcastle ENDOPREM for use in Cytosponge.

An irritable bowel syndrome subtype defined by species-specific alterations in faecal microbiota.

BACKGROUND AND AIMS: Irritable bowel syndrome (IBS) is a common functional gastrointestinal disorder that may be triggered by enteric pathogens and has also been linked to alterations in the microbiota and the host immune response. The authors performed a detailed analysis of the faecal microbiota in IBS and control subjects and correlated the findings with key clinical and physiological parameters. DESIGN: The authors used pyrosequencing to determine faecal microbiota composition in 37 IBS patients (mean age 37 years; 26 female subjects; 15 diarrhoea-predominant IBS, 10 constipation-predominant IBS and 12 alternating-type IBS) and 20 age- and gender-matched controls. Gastrointestinal and psychological symptom severity and quality of life were evaluated with validated questionnaires and colonic transit time and rectal sensitivity were measured. RESULTS: Associations detected between microbiota composition and clinical or physiological phenotypes included microbial signatures associated with colonic transit and levels of clinically significant depression in the disease. Clustering by microbiota composition revealed subgroups of IBS patients, one of which (n=15) showed normal-like microbiota composition compared with healthy controls. The other IBS samples (n=22) were defined by large microbiota-wide changes characterised by an increase of Firmicutes-associated taxa and a depletion of Bacteroidetes-related taxa. CONCLUSIONS: Detailed microbiota analysis of a well-characterised cohort of IBS patients identified several clear associations with clinical data and a distinct subset of IBS patients with alterations in their microbiota that did not correspond to IBS subtypes, as defined by the Rome II criteria.
