ABSTRACT

BACKGROUND: Approximately half of the substance dependence treatment population is estimated to have a cognitive impairment, which reduces participation, retention, and post-treatment outcomes. Cognitive behaviour change approaches are less effective for this population and cognitive remediation strategies have been found to improve outcomes. Evidence on modified programs to remove environmental barriers for treatment seekers with disability does not exist. OBJECTIVE: A modified residential substance misuse treatment program in New South Wales, Australia, was piloted and evaluated to address this knowledge gap. METHOD: Of 67 residents who received treatment during the evaluation period, 33 were screened as having cognitive impairment. Twelve residents took part in an interview and 10 staff in a focus group to understand their views of the pilot program. Resident characteristics and retention rates and themes about program benefits and challenges are reported. RESULTS: Treatment completion was up to five times higher for residents with cognitive impairment after the new program was implemented. The pilot program provided simplified written and visual materials and concrete examples and introduced a daily virtues program to embed new learning and support behaviour change. Resources to allow staff to engage more intensively with residents and provision of ongoing staff training were viewed as essential for program success. CONCLUSIONS: Environmental adaptations, including a combination of conventional treatment modalities with accessible design and person-centred principles, removed barriers to treatment for residents with cognitive impairment. Creating a climate where respect, tolerance and peer support were normalised was likely to have been particularly beneficial for these residents.

ABSTRACT

OBJECTIVES: The prosthesis type for multiple valve surgery (replacement of two or more diseased native or prosthetic valves, replacement of two diseased valves with repair/reconstruction of a third, or replacement of a single diseased valve with repair/reconstruction of a second valve) remains inadequately evaluated. The clinical performance of multiple valve surgery with bioprostheses (BP) and mechanical prostheses (MP) was assessed to compare patient survival and composites of valve-related complications. METHODS: Between 1975 and 2000, 1245 patients had multiple valve surgery (BP 785, mean age 62.0 ± 14.7 years; and MP 460, mean age 56.9 ± 12.9 years). There were 1712 procedures performed [BP 969(56.6%) and MP 743(43.4%). Concomitant coronary artery bypass (conCABG) was BP 206(21.3%) and MP 105(14.1%) (p = 0.0002). The cumulative follow-up was BP 5131 years and MP 3364 years. Independent predictors were determined for mortality, valve-related complications and composites of complications. RESULTS: Unadjusted patient survival at 12 years was BP 52.1 ± 2.1% and MP 54.8 ± 4.6% (p = 0.1127), while the age adjusted survival was BP 48.7 ± 2.3% and MP 54.4 ± 5.0%. The predictors of overall mortality were age [Hazard Ratio (HR) 1.051, p < 0.0001], previous valve (HR 1.366, p = 0.028) and conCABG (HR 1.27, p = 0.021). The actual freedom from valve-related mortality at 12 years was BP 85.6 ± 1.6% and MP 91.0 ± 1.6% (actuarial p = 0.0167). The predictors of valve-related mortality were valve type (BP > MP) (2.61, p = 0.001), age (HR 1.032, p = 0.0005) and previous valve (HR 12.61, p < 0.0001). The actual freedom from valve-related reoperation at 12 years was BP 60.8 ± 1.9% and MP85.6 ± 2.1% (actuarial p < 0.001). The predictors of valve-related reoperation were valve type (MP > BP) (HR 0.32, p < 0.0001), age (HR 0.99, p = 0.0001) and previous valve (HR 1.38, p = 0.008) CONCLUSIONS: Overall survival (age adjusted) is differentiated by valve type over 10 and 12 years and valve-related mortality and valve-related reoperation favours the use of mechanical prostheses, overall for multiple valve surgery.

ABSTRACT

BACKGROUND: Antimicrobial resistance (AMR) is being recognized as a priority by healthcare organizations across the world. However, many children are managed on IV antimicrobials in hospital with very little consideration of antimicrobial stewardship issues. OBJECTIVES: A nurse-led paediatric ambulatory outpatient parenteral antimicrobial therapy (OPAT) service, managing children with common infections being ambulated on short courses of IV antimicrobials, was introduced within Southampton Children's Hospital in January 2018. We evaluated the impact of this service in terms of the quality of antimicrobial prescribing and timing of ambulation in children presenting with common infections. METHODS: All cases managed within the service were reviewed in two separate 2 month time periods: prior to introduction of the service (September-October 2016) and then prospectively after its introduction (September-October 2018). RESULTS: A total of 96% of IV antibiotic management decisions at 48 h were deemed appropriate in 2018, compared with 75% in 2016. A total of 64% of patients were ambulated on IV antibiotics at some point during their treatment course in 2018, compared with 19% in 2016. However, a significant proportion of antimicrobial decisions made at the point of presentation to hospital remained suboptimal in 2018. CONCLUSIONS: Children are commonly managed with IV antibiotics in hospital. We demonstrate marked improvements in appropriate antimicrobial use through the introduction of a nurse-led ambulatory OPAT service. In addition, such a service can promote a greater proportion of children being ambulated from hospital, freeing up valuable inpatient beds and potentially delivering cost savings that can be used to fund such services.

ABSTRACT

A 70 kg, 34-year-old woman at 29 weeks-of-gestation required intrauterine transfusion for Rh (D) alloimmunization. In the ambulatory treatment clinic, 19 mg of rocuronium was administered intramuscularly in split doses into the fetal buttock. The fetus moved and inadvertent maternal neuromuscular blockade occurred, leading to respiratory distress. The patient was transferred to the operating room where she had poor muscle tone, dyspnea and dysphonia. Sugammadex 100 mg was administered intravenously and complete resolution of neuromuscular blockade was demonstrated using a Neuromuscular Transmission™ monitor. When neuromuscular blocking agents are administered in ambulatory settings, management protocols, reversal agents, and skilled assistance should be immediately available for managing potentially life-threatening complications.

ABSTRACT

Tablet computers have emerged as increasingly useful tools in medical education, particularly for assessment. However, it is not fully established whether tablet computers influence the quality and/or quantity of feedback provided in high stakes assessments. It is also unclear how electronically-recorded feedback relates to student performance. Our primary aim was to determine whether differences existed in feedback depending on the tool used to record it. METHODS: We compared quantitative and qualitative feedback between paper-scoring sheets versus iPads™ across two consecutive years of a final year MBChB (UK medical degree) Objective Structured Clinical Examination. Quality of comments (using a validated five-point rating scale), number of examiner comments and number of words were compared across both methods of recording assessment performance using chi-squared analysis and independent t-test. We also explored relationships between student performance (checklist and global scoring) and feedback. RESULTS: Data from 190 students (2850 paper scored interactions) in 2015 and 193 (2895 iPad™ scored interactions) in 2016 were analysed. Overall, a greater number of comments were given with iPad™ compared to written (42% versus 20%; p < 0.001) but the quality of feedback did not differ significantly. For both written and electronic feedback, students with low global scores were more likely to receive comments (p < 0.001). CONCLUSION: The use of iPads™ in high stakes assessment increases the quantity of feedback compared to traditional paper scoring sheets. The quantity and quality of feedback for poorer performing candidates (by global score) were also better with iPad™ feedback.

ABSTRACT

OBJECTIVES: To investigate the effects of a four week jump training program on frontal plane projection angle (FPPA) in young female gymnasts. DESIGN: Intervention study, consisting of a four week jump training program performed for 15 min as part of a warm-up, three days per week for four weeks. SETTING: Gymnastics training center. PARTICIPANTS: Fourteen youth female gymnasts (age: 13.5 ± 2.14 years, height: 1.54 ± 0.11 m, body mass: 46.23 ± 7.68 kg). MAIN OUTCOME MEASURES: Change in FPPA during a 30 cm drop landing and tuck back somersault. RESULTS: Large and significant decreases (p < 0.001) in FPPA of 6.8° (39%) and 8.4° (37%) during the drop landing and tuck back somersault, respectively. CONCLUSION: The jump training program was successful in improving FPPA in female gymnasts and is advised to be implemented into the warm-ups and training programs of competitive female gymnasts to improve FPPA and therefore reduce the risk factors associated with knee injuries.

ABSTRACT

OBJECTIVE: To compare outcomes of patients with pure adenocarcinoma-in-situ (AIS) and mixed AIS/CIN 2/3 lesions including the incidence of AIS persistence, recurrence and progression to adenocarcinoma. DESIGN: Retrospective cohort study. SETTING: Statewide population in Western Australia. POPULATION: Women diagnosed with AIS between 2001 and 2012. METHODS: We conducted a retrospective, population-based cohort study. MAIN OUTCOME MEASURES: De-identified linked data were utilised to ascertain the association between patient age at excisional treatment, margin status, lesion type, lesion size, and risk of persistent AIS (defined as the presence of AIS <12 months from treatment), recurrent AIS (≥12 months post-treatment), and adenocarcinoma. RESULTS: 636 patients were eligible for analysis. The mean age was 32.3 years and median follow-up interval was 2.5 years. Within the study cohort, 266 patients (41.8%) had pure AIS and 370 (58.2%) had mixed AIS/CIN 2/3. Overall, 47 patients (7.4%) had AIS persistence/recurrence and 12 (1.9%) had adenocarcinoma. Factors associated with persistence/recurrence were pure AIS (hazard ratio (HR) 2.3; 95%CI 1.28-3.94; P = 0.005), age >30 years (HR 2.1; 95%CI 1.16-3.81; P = 0.015), positive endocervical margins (HR 5.8; 95%CI 3.05-10.92; P = <0.001) and AIS lesions >8 mm (HR 2.5; 95%CI 1.00-6.20; P = 0.049). A histologically positive AIS ectocervical margin was not associated with persistence/recurrence. CONCLUSION: In this study, pure AIS was associated with greater risk of persistence/recurrence than was mixed AIS/CIN 2/3. AIS lesions >8 mm and positive endocervical margins were significant predictors for persistent or recurrent disease. TWEETABLE ABSTRACT: Pure cervical adenocarcinoma-in-situ (AIS) may have greater risk of recurrence than AIS co-existing with CIN 2/3.

ABSTRACT

OBJECTIVE: To determine whether human papillomavirus (HPV) immunisation has affected the prevalence of HPV genotypes and colposcopic features of cervical intraepithelial neoplasia (CIN) in young women referred for colposcopy. DESIGN: A two-centre observational study including vaccinated and unvaccinated women. SETTING: Colposcopy clinics serving two health regions in Scotland, UK. POPULATION: A total of 361 women aged 20-25 years attending colposcopy following an abnormal cervical cytology result at routine cervical screening. METHODS: Cervical samples were obtained from women for HPV DNA genotyping and mRNA E6/E7 expression of HPV 16, 18, 31, 33, and 45. Demographic data, cytology, and histology results and colposcopic features were recorded. Chi-square analysis was conducted to identify associations between vaccine status, HPV genotypes, and colposcopic features. MAIN OUTCOME MEASURES: Colposcopic features, HPV genotypes, mRNA expression, and cervical histology. RESULTS: The prevalence of HPV 16 was significantly lower in the vaccinated group (8.6%) compared with the unvaccinated group (46.7%) (P = 0.001). The number of cases of CIN2+ was significantly lower in women who had been vaccinated (P = 0.006). The HPV vaccine did not have a statistically significant effect on commonly recognised colposcopic features, but there was a slight reduction in the positive predictive value (PPV) of colposcopy for CIN2+, from 74% (unvaccinated) to 66.7% (vaccinated). CONCLUSIONS: In this group of young women with abnormal cytology referred to colposcopy, HPV vaccination via a catch-up programme reduced the prevalence of CIN2+ and HPV 16 infection. The reduced PPV of colposcopy for the detection of CIN2+ in women who have been vaccinated is at the lower acceptable level of the UK national cervical screening programme guidelines. TWEETABLE ABSTRACT: Reduction of hrHPV positivity and CIN in immunised women consistent with lower PPV of colposcopy for CIN2+.

ABSTRACT

BACKGROUND: The concept of neurogenic thoracic outlet syndrome (N-TOS) including upper and lower plexus syndromes secondary to soft tissue neck injury after motor vehicle collisions (MVCs) has been contentious. We considered that analysis of objective data from this group of patients could provide insight into this controversial type of N-TOS. METHODS: During the 10-year period January 2001 through December 2010 we examined patients who had received a diagnosis of N-TOS following an MVC. We graded the principal diagnosis based on the objective data from our physical examination. RESULTS: In total 263 patients received a diagnosis of N-TOS during the study period. At the highest accuracy level of diagnosis there were 56 patients with ulnar entrapment syndrome (UES), 40 with carpal tunnel syndrome (CTS) and 55 with nonorganic disease (NOD), for a total of 151 (57.4%) cases in which the diagnosis of N-TOS was brought into question. The elevated arm stress test (EAST) reproduced the symptoms of UES in 33 of the 56 patients of UES (58.9%) and reproduced the symptoms of CTS in 18 of the 40 patients with CTS (45.0%). CONCLUSION: There appears to be a high incidence of misdiagnosis of N-TOS following MVCs. The EAST is not a prime test for N-TOS.


BACKGROUND: Il n'y a pas consensus sur le concept de syndrome du défilé thoraco-brachial (SDTB) neurogène comprenant des syndromes du plexus brachial inférieur et supérieur consécutifs à une blessure aux tissus mous du cou découlant d'une collision de véhicules motorisés. Nous avons pensé que l'analyse de données objectives sur les patients touchés pourrait aider à comprendre ce type controversé de SDTB neurogène. METHODS: Durant une période de 10 ans, soit de janvier 2001 à décembre 2010, nous avons examiné des patients ayant reçu un diagnostic de SDTB neurogène après une collision de véhicules motorisés. Nous avons coté le diagnostic principal selon les données objectives de notre examen physique. RESULTS: Au total, 263 patients ont reçu un diagnostic de SDTB neurogène durant la période à l'étude. Au degré le plus précis de diagnostic, 56 patients étaient atteints de syndrome canalaire du nerf cubital, 40, de syndrome du canal carpien et 55, de maladies non organiques, pour un total de 151 patients, ou 57,4 % des cas pour lesquels le diagnostic de SDTB neurogène avait été envisagé. La manoeuvre du chandelier (test de Roos) a reproduit les symptômes du syndrome canalaire du nerf cubital chez 33 des 56 patients atteints (58,9 %) et ceux du syndrome du canal carpien chez 18 des 40 patients atteints (45,0 %). CONCLUSION: Il semble y avoir une forte incidence de mauvais diagnostics de SDTB neurogène après des collisions de véhicules motorisés. Le test de Roos n'est pas un test de premier choix pour ce syndrome.

ABSTRACT

BACKGROUND: Colorectal cancers arise from benign adenomas, although not all adenomas progress to cancer and there are marked interpatient differences in disease progression. We have previously associated KRAS mutations with disease progression and reduced survival in colorectal cancer patients. METHODS: We used TaqMan low-density array (TLDA) qRT-PCR analysis to identify miRNAs differentially expressed in normal colorectal mucosa, adenomas and cancers and in isogeneic KRAS WT and mutant HCT116 cells, and used a variety of phenotypic assays to assess the influence of miRNA expression on KRAS activity, chemosensitivity, proliferation and invasion. RESULTS: MicroRNA-224 was differentially expressed in dysplastic colorectal disease and in isogeneic KRAS WT and mutant HCT116 cells. Antagomir-mediated miR-224 silencing in HCT116 KRAS WT cells phenocopied KRAS mutation, increased KRAS activity and ERK and AKT phosphorylation. 5-FU chemosensitivity was significantly increased in miR-224 knockdown cells, and in NIH3T3 cells expressing KRAS and BRAF mutant proteins. Bioinformatics analysis of predicted miR-224 target genes predicted altered cell proliferation, invasion and epithelial-mesenchymal transition (EMT) phenotypes that were experimentally confirmed in miR-224 knockdown cells. CONCLUSIONS: We describe a novel mechanism of KRAS regulation, and highlight the clinical utility of colorectal cancer-specific miRNAs as disease progression or clinical response biomarkers.

ABSTRACT

From origins in their heartlands in Easter Ross, clan Munro produced no fewer than three distinct medical dynasties, all descended from Hugh Munro, 9th Baron Foulis (c1352-1425), 12th chief of the clan. This paper describes what we believe to be a unique family of related medical dynasties which were influential in Edinburgh, London and the Scottish Highlands. It sets out in detail the family genealogy, provides some biographical information, and explores the reasons for the development of such medical dynasties, which appear to be different for each of the three dynasties within this family. The 'Edinburgh Monros' included the three Alexanders Monro, primus, secundus and tertius, who between them occupied the university chair of Anatomy at the University of Edinburgh for 126 years from 1720. Dr David Monro, son of Alexander Monro tertius, emigrated to New Zealand where his descendants included several doctors, the last of whom died in 2013. The 'Bedlam Monros' achieved fame, and some notoriety, in managing mental illness in London for the 154 years from 1728-1882. In contrast, the 'Bonesetter Munros' practised their skills in the local community in Ross-shire and one of them attracted patients from all over Britain. They practised their trade for over 100 years from the start of the 19th to the early 20th century.

ABSTRACT

OBJECTIVE: To compare the outcomes of patients with cervical adenocarcinoma in situ (ACIS) treated with cold knife cone (CKC) biopsy or loop electrosurgical excision procedure (LEEP) for the treatment of cervical adenocarcinoma in situ (ACIS). STUDY DESIGN: This is a retrospective, population-based cohort study of Western Australian patients with ACIS diagnosed between 2001 and 2012. Outcomes included pathological margin status and the incidence of persistent or recurrent endocervical neoplasia (ACIS and adenocarcinoma) during follow-up (<12 months) and surveillance (≥12 months) periods. RESULTS: The study group comprised 338 patients including 107 (32%) treated initially by LEEP and 231 (68%) treated by CKC biopsy. The mean age was 33.2 years (range 18 to 76 years) and median follow-up interval was 3.6 years (range <1 year to 11.8 years). Overall, 27 (8.0%) patients had ACIS persistence/recurrence while 9 (2.7%) were diagnosed with adenocarcinoma during the follow-up and surveillance periods. No patient died of cervical cancer within the study period. There were no significant differences in the incidence of persistent and/or recurrent endocervical neoplasia according to the type of excisional procedure. Patients with positive biopsy margins were 3.4 times more likely to have disease persistence or recurrence. CONCLUSION(S): LEEP and CKC biopsy appear equally effective in the treatment of ACIS for women wishing to preserve fertility. Patients undergoing conservative management for ACIS should be closely monitored, particularly if biopsy margins are positive in initial excision specimens. Patients and their clinicians should be aware of the potential risks of residual and recurrent disease.

ABSTRACT

Sharing injecting paraphernalia (containers, filters and water) poses a risk of transmitting the hepatitis C virus (HCV). The prevalence of, and risk of HCV from, such behaviour has not been extensively reported in Europe. People who inject drugs (PWID) were recruited in cross-sectional surveys from services providing sterile injecting equipment across Scotland between 2008 and 2010. Participants completed a questionnaire and provided a blood spot for anonymous testing. Logistic regression was used to examine the association between recent HCV infection (anti-HCV negative and HCV-RNA positive) and self-reported measures of injecting equipment sharing in the 6 months preceding interview. Twelve per cent of the sample reported sharing needles/syringes, and 40% reported sharing paraphernalia in the previous 6 months. The adjusted odds ratios (AOR) for sharing needles/syringes (+/- paraphernalia), and sharing only paraphernalia in the last 6 months were 6.7 (95% CI 2.6-17.1) and 3.0 (95% CI 1.2-7.5), respectively. Among those who reported not sharing needles/syringes, sharing containers and filters were both significantly associated with recent HCV infection (AOR 3.1, 95% CI 1.3-7.8 and 3.1, 95% CI 1.3-7.5, respectively); sharing water was not. We present the first study to apply a cross-sectional approach to the analysis of the association between sharing paraphernalia and incident HCV infection and demonstrate consistent results with previous longitudinal studies. The prevalence of paraphernalia sharing in our study population is high, representing significant potential for HCV transmission.

ABSTRACT

BACKGROUND: The microcirculation is responsible for distribution of blood within tissues, delivery of oxygen and other nutrients, and regulation of blood pressure. The objective of this study was to compare the sublingual microcirculation of pregnant participants to that of comparable non-pregnant volunteers. METHODS: Two groups of participants were recruited: a group of pregnant, non-laboring women with singleton pregnancies at term gestation and a control group of age-comparable non-pregnant volunteers. A sidestream dark field imaging device was applied to the sublingual mucosal surface obtaining a steady image for at least 20 s duration, in five visual fields. The resultant five video clips per participant were analyzed blindly and at random to prevent coupling between images. The mean microvascular flow index values for each group were compared using a paired t-test. RESULTS: Thirty-seven participants were recruited (19 pregnant, 18 non-pregnant); a single pregnant participant was withdrawn because of technical issues. Baseline characteristics were similar with the exception of weight and body mass index. The mean microvascular flow index was significantly higher in the pregnant group 2.7 ± 0.2 compared to the non-pregnant group 2.5 ± 0.3 (P = 0.021), while the perfused vessel density and proportion of perfused vessels were not significantly different (P = 0.707 and 0.403, respectively). CONCLUSION: The microvascular flow index of pregnant women is higher than a comparable non-pregnant group, which appears to correlate with the physiological changes of pregnancy.

ABSTRACT

Norman Bethune became famous through his work in the Spanish Civil War, his advocacy of socialised medicine in North America and his association with Mao Zedong's revolutionary movement in China. It has been suggested that he may have been descended from the Bethune or Beaton medical dynasty, who for generations served as physicians to kings of Scotland, the Lords of the Isles and to some of the larger Scottish clans. This paper traces his lineage back to the Isle of Skye. In the absence of old parish records as aids to tracing genealogy, other available evidence has confirmed that Bethune was indeed in the direct line of descent from the Bethunes or Beatons of Husabost, in Skye, one of the largest branches of this medical kindred, who were physicians to the MacLeods of Dunvegan.

BACKGROUND: Multidisciplinary team meetings (MDTs), also known as tumour boards or multidisciplinary case conferences, are an integral component of contemporary cancer care. There are logistical problems with setting up and maintaining participation in these meetings. An ill-defined concept, the virtual MDT (vMDT), has arisen in response to these difficulties. We have, in order to provide clarity and to generate discussion, attempted to define the concept of the vMDT, outline its advantages and disadvantages, and consider some of the practical aspects involved in setting up a virtual MDT. METHODS: This is an unstructured review of published evidence and personal experience relating to virtual teams in general, and to MDTs in particular. RESULTS: We have devised a simple taxonomy for MDTs, discussed some of the practicalities involved in setting up a vMDT, and described some of the potential advantages and disadvantages associated with vMDTs. CONCLUSION: The vMDT may be useful for discussions concerning rare or unusual tumours, or for helping guide the assessment and management of patients with uncommon complications related to treatment. However, the vMDT is a niche concept and is currently unlikely to replace the more traditional face-to-face MDT in the management of common tumours at specific sites.

ABSTRACT

OBJECTIVE: Aspirin is associated with a reduced risk of developing colorectal cancer. This study examined whether patients with colorectal cancer prescribed aspirin had improved survival. DESIGN: An observational population cohort study was undertaken using data linkage of cancer registry, dispensed prescriptions and death certificate records in Tayside, Scotland. All community prescribed aspirin pre- and post-diagnosis was extracted and periods of aspirin use post-diagnosis for each individual were analysed using Cox proportional hazard models. Main outcome measures were all-cause and colorectal mortality from death certificates. RESULTS: Two thousand nine hundred ninety patients were identified with colorectal cancer between 1st January 1997 and 30th December 2006 and followed up until 28th February 2010. Median age at diagnosis was 73 (interquartile range [IQR] 65-80) with 52% male. One thousand nine hundred ninety-eight (67%) deaths were recorded with 1021 (34%) attributed to colorectal cancer. One thousand three hundred forty (45%) patients used aspirin at some stage of the study period. Aspirin use post-diagnosis was associated with lower risk of all cause mortality (hazard ratio [HR]=0.67, 95% confidence interval [CI]=0.57-0.79, p<0.001) and colorectal cancer specific mortality after allowing for age, Dukes' stage, gender, socio-economic status and aspirin use pre-diagnosis. Increasing age and stage at diagnosis were associated with increased risk, with more affluent patients at reduced risk. CONCLUSIONS: Our study suggests that aspirin use post-diagnosis of colorectal cancer may reduce both all cause and colorectal cancer specific mortality. However further work is required to ensure this is a causal relationship and to identify whether it is best used in specific groups of patients.
