Suppression of the postoperative neutrophil leucocytosis following neoadjuvant chemoradiotherapy for rectal cancer and implications for surgical morbidity
Objective: The extent to which neoadjuvant chemoradio-
therapy for rectal cancer influences postoperative morbid-
ity is controversial. This study investigated whether this
treatment suppresses the normal perioperative inflamma-
tory response and explored the clinical implications.
Method: Prospective databases were queried to identify
37 consecutive study patients undergoing definitive
surgery following 5-FU ⁄ capecitabine-based chemoradio-
therapy and 35 consecutive untreated control patients
operated upon for rectal or rectosigmoid cancer. Preop-
erative (< 10 days) and postoperative (< 24 h) neutrophil
counts, along with morbidity data, were confirmed
retrospectively. Univariate and multivariate analyses
assessed the apparent effect of chemoradiotherapy on
change in neutrophil count. The latter’s association with
postoperative morbidity was then examined.
Results: Sufficient data were available for 34 study and
27 control patients. Repeated-measures ANCOVA
revealed significant differences between their periopera-
tive neutrophil counts (P = 0.02). Of the other charac-
teristics which differed between the groups, only age
and tumour location were prognostically significant
regarding perioperative change in neutrophil count.
Accounting for relevant covariates, chemoradiotherapy
was significantly associated with a suppressed perioper-
ative neutrophil leucocytosis. Local postoperative com-
plications affected 25 of 61 patients, who had lower
perioperative neutrophil increases than their counter-
parts (P = 0.016).
Conclusion: Chemoradiotherapy appears to suppress the
perioperative inflammatory response, thereby increasing
susceptibility to local postoperative complications
Dysphagia training for speech-language pathologists: implications for clinical practice
There are competency standards available in countries with established speech-language pathology services to guide basic dysphagia training with ongoing workplace mentoring for advanced skills development. Such training processes, however, are not as well established in countries where speech-language pathology training and practice is relatively new, such as Malaysia. The current study examines the extent of dysphagia training and workplace support available to speech-language pathologists (SLPs) in Malaysia and Queensland, Australia, and explores clinicians’ perceptions of the training and support provided, and of their knowledge, skills, and confidence. Using a matched cohort cross-sectional design, a purpose-built survey was administered to 30 SLPs working in Malaysian government hospitals and 30 SLPs working in Queensland Health settings in Australia. Malaysian clinicians were found to have received significantly less university training, less mentoring in the workplace, and were lacking key infrastructure needed to support professional development in dysphagia management. Over 90% of Queensland clinicians were confident and felt they had adequate skills in dysphagia management; in contrast, significantly lower levels of knowledge, skills, and confidence were observed in the Malaysian cohort. The findings identify a need for improved university training and increased opportunities for workplace mentoring, training, and support for Malaysian SLPs
Reasonable expectations of privacy in non-disclosure of familial genetic risk: What is it reasonable to expect?
Where there is conflict between a patient's interests in non-disclosure of their genetic information to relatives and the relative's interest in knowing the information because it indicates their genetic risk, clinicians have customarily been able to protect themselves against legal action by maintaining confidence even if, professionally, they did not consider this to be the right thing to do. In ABC v St Georges Healthcare NHS Trust ([2017] EWCA Civ 336) the healthcare team recorded their concern about the wisdom of the patient's decision to withhold genetic risk information from his relative, but chose to respect what they considered to be an unwise choice. Even though professional guidance considers that clinicians have the discretion to breach confidence where they believe this to be justified, (Royal College of Physicians, Royal College of Pathologists and the British Society of Human Genetics, 2006; GMC, 2017) clinicians find it difficult to exercise this discretion in line with their convictions against the backdrop of the legal prioritisation of the duty to maintain confidence. Thus, the professional discretion is not being freely exercised because of doubts about the legal protection available in the event of disclosure. The reliance on consent as the legal basis for setting aside the duty of confidence often vetoes sharing information with relatives. This paper argues that an objective approach based on privacy, rather than a subjective consent-based approach, would give greater freedom to clinicians to exercise the discretion which their professional guidance affords
Complexity of case mix in a regional allergy service
<p>Abstract</p> <p>Background</p> <p>Currently in the United Kingdom (UK), there is a mismatch between limited financial resources and the large proportion of patients with suspected allergies actually being referred to specialist allergy clinics. To better understand the case mix of patients being referred, we audited referrals to a regional allergy service over an 8 year period.</p> <p>The main source of data was consultant letters to General Practitioners (GP) summarising the diagnosis of patients, archived from January 2002 to September 2009. Letters were reviewed, extracting the clinic date, doctor seen, gender, date of birth, postcode, GP, and diagnoses. Diagnoses were classified into seven groups and illustrative cases for each group noted.</p> <p>Findings</p> <p>Data from 2,028 new referrals with suspected allergy were analysed. The largest group of patients (43%) were diagnosed with a type I hypersensitivity. The other diagnostic groups were chronic idiopathic (spontaneous) urticaria (35%), suspected type I hypersensitivity but no allergen identified (8%), idiopathic (spontaneous) angioedema (8%), physical urticaria (2.5%), non-allergic symptoms (1.6%), type IV hypersensitivity (0.8%) and ACE inhibitor sensitivity (0.5%). Two thirds of patients seen were female with a higher percentage of female patients in the non type-I hypersensitivity group (71%) than the type 1 hypersensitivity (66%) (χ<sup>2 </sup>= 5.1, 1df, <it>p = 0.024</it>). The type 1 hypersensitivity patients were younger than other patients (38 Vs 46 years, t = -10.8, <it>p < 0.001</it>)</p> <p>Conclusions</p> <p>This study highlights the complexity of specialist allergy practice and the large proportion of patients referred with non-type I hypersensitivities, chronic idiopathic (spontaneous) urticaria being by far the largest group. Such information is critical to inform commissioning decisions, define referral pathways and in primary care education.</p
A toolkit for incorporating genetics into mainstream medical services: Learning from service development pilots in England
Background:
As advances in genetics are becoming increasingly relevant to mainstream healthcare, a major challenge is to ensure that these are integrated appropriately into mainstream medical services. In 2003, the Department of Health for England announced the availability of start-up funding for ten 'Mainstreaming Genetics' pilot services to develop models to achieve this.
Methods:
Multiple methods were used to explore the pilots' experiences of incorporating genetics which might inform the development of new services in the future. A workshop with project staff, an email questionnaire, interviews and a thematic analysis of pilot final reports were carried out.
Results:
Seven themes relating to the integration of genetics into mainstream medical services were identified: planning services to incorporate genetics; the involvement of genetics departments; the establishment of roles incorporating genetic activities; identifying and involving stakeholders; the challenges of working across specialty boundaries; working with multiple healthcare organisations; and the importance of cultural awareness of genetic conditions.
Pilots found that the planning phase often included the need to raise awareness of genetic conditions and services and that early consideration of organisational issues such as clinic location was essential. The formal involvement of genetics departments was crucial to success; benefits included provision of clinical and educational support for staff in new roles. Recruitment and retention for new roles outside usual career pathways sometimes proved difficult. Differences in specialties' working practices and working with multiple healthcare organisations also brought challenges such as the 'genetic approach' of working with families, incompatible record systems and different approaches to health professionals' autonomous practice.
'Practice points' have been collated into a Toolkit which includes resources from the pilots, including job descriptions and clinical tools. These can be customised for reuse by other services.
Conclusions:
Healthcare services need to translate advances in genetics into benefits for patients. Consideration of the issues presented here when incorporating genetics into mainstream medical services will help ensure that new service developments build on the body of experience gained by the pilots, to provide high quality services for patients with or at risk of genetic conditions
Consensus-building on developing dysphagia competence: A North West of England perspective
© 2017 Royal College of Speech and Language Therapists. Background: Dysphagia has been an increasing area of practice for speech and language therapists (SLTs) for over 20 years, and throughout that period there has been debate about how practical skills in dysphagia can best be developed. The implementation of the new Royal College of Speech and Language Therapists (RCSLT) framework was considered from a regional perspective seeking to establish consensus across different speech and language therapy settings. Aim: To explore practical solutions to the development of dysphagia competency in new graduates whilst acknowledging the wide variation in staffing and clinical dysphagia experience across the geographical and clinical landscape in the North West of England. Methods & Procedures: A four-phase study involved a literature search; interviews with experts in the field of dysphagia; a survey to identify current practice; and a two-round Delphi process. Outcomes & Results: Five themes emerged for dysphagia competency development: development of practical skills; supervision; clinical excellence networks; workforce planning; and postgraduate formal training. Challenges, and solutions to these, were identified through the phases of the study. A model for dysphagia competency development relevant to the North West context was achieved by consensus. Conclusions & Implications: There are many practical ways of developing dysphagia competency. The themes and model generated provide constructive support to services in adopting the most appropriate methods for their own settings
Post mortem magnetic resonance imaging in the fetus, infant and child: A comparative study with conventional autopsy (MaRIAS Protocol)
<p>Abstract</p> <p>Background</p> <p>Minimally invasive autopsy by post mortem magnetic resonance (MR) imaging has been suggested as an alternative for conventional autopsy in view of the declining consented autopsy rates. However, large prospective studies rigorously evaluating the accuracy of such an approach are lacking. We intend to compare the accuracy of a minimally invasive autopsy approach using post mortem MR imaging with that of conventional autopsy in fetuses, newborns and children for detection of the major pathological abnormalities and/or determination of the cause of death.</p> <p>Methods/Design</p> <p>We recruited 400 consecutive fetuses, newborns and children referred for conventional autopsy to one of the two participating hospitals over a three-year period. We acquired whole body post mortem MR imaging using a 1.5 T MR scanner (Avanto, Siemens Medical Solutions, Enlargen, Germany) prior to autopsy. The total scan time varied between 90 to 120 minutes. Each MR image was reported by a team of four specialist radiologists (paediatric neuroradiology, paediatric cardiology, paediatric chest & abdominal imaging and musculoskeletal imaging), blinded to the autopsy data. Conventional autopsy was performed according to the guidelines set down by the Royal College of Pathologists (UK) by experienced paediatric or perinatal pathologists, blinded to the MR data. The MR and autopsy data were recorded using predefined categorical variables by an independent person.</p> <p>Discussion</p> <p>Using conventional post mortem as the gold standard comparator, the MR images will be assessed for accuracy of the anatomical morphology, associated lesions, clinical usefulness of information and determination of the cause of death. The sensitivities, specificities and predictive values of post mortem MR alone and MR imaging along with other minimally invasive post mortem investigations will be presented for the final diagnosis, broad diagnostic categories and for specific diagnosis of each system.</p> <p>Clinical Trial Registration</p> <p><a href="http://www.clinicaltrials.gov/ct2/show/NCT01417962">NCT01417962</a></p> <p><b>NIHR Portfolio Number: </b>6794</p

Reliability and validity of needle biopsy evaluation of breast-abnormalities using the B-categorization – design and objectives of the Diagnosis Optimisation Study (DIOS)
<p>Abstract</p> <p>Background</p> <p>The planned nationwide implementation of mammography screening 2007 in Germany will increase the occurrence of mammographically detected breast abnormalities. These abnormalities are normally evaluated by minimal invasive core biopsy. To minimize false positive and false negative histological findings, quality assurance of the pathological evaluation of the biopsies is essential. Various guidelines for quality assurance in breast cancer diagnosis recommend applying the B-classification for histopathological categorization. However, to date there are only few studies that reported results about reliability and validity of B-classification. Therefore, objectives of our study are to determine the inter- and intraobserver variability (reliability study) and construct and predictive validity (validity study) of core biopsy evaluation of breast abnormalities. This paper describes the design and objectives of the DIOS Study.</p> <p>Methods/Design</p> <p>All consecutive asymptomatic and symptomatic women with breast imaging abnormalities who are referred to the University Hospital of Halle for core breast biopsy over a period of 24 months are eligible. According to the sample size calculation we need 800 women for the study. All patients in the study population underwent clinical and radiological examination. Core biopsy is performed by stereotactic-, ultrasound- or magnetic resonance (MR) guided automated gun method or vacuum assisted method. The histopathologic agreement (intra- and interobserver) of pathologists and the histopathologic validity will be evaluated. Two reference standards are implemented, a reference pathologist and in case of suspicious or malignant findings the histopathologic result of excision biopsy. Furthermore, a self administrated questionnaire which contains questions about potential risk factors of breast cancer, is sent to the participants approximately two weeks after core biopsy. This enables us to run a case-control-analysis (woman with breast cancer histological verified after excision are defined as cases, woman without malignant breast lesions are defined as controls) to investigate the predictive values of various risk factors on breast cancer risk.</p> <p>Conclusion</p> <p>The analysis of reliability and validity of the histopathological evaluation of core biopsy specimens of breast abnormalities is intended to provide important information needed for a high quality in breast cancer diagnostic and for planning of treatment strategies.</p
