COVID-19 infection in patients with intestinal failure: UK experience.

BACKGROUND: The direct effect of the coronavirus disease 2019 (COVID-19) pandemic on patients with intestinal failure (IF) has not been described. METHODS: We conducted a nationwide study of UK IF centers to evaluate the infection rates, presentations, and outcomes in patients with types 2 and 3 IF. RESULTS: A total of 45 patients with IF contracted COVID-19 between March and August 2020; this included 26 of 2191 (1.2%) home parenteral nutrition (HPN)-dependent adults and 19 of 298 (6.4%) adults hospitalized with type 2 IF. The proportion of patients receiving nursing care for HPN administration was higher in those with community-acquired COVID-19 (66.7%) than the proportion in the entire HPN cohort (26.1%; P < .01). Two HPN-dependent and 1 hospitalized patient with type 2 IF died as a direct consequence of the virus (6.7% of 45 patients with types 2 or 3 infected). CONCLUSION: This is the first study to describe the outcomes of COVID-19 in a large cohort of patients requiring long-term PN. Methods to reduce hospital and community nosocomial spread would likely be beneficial.

Associations between ApoE gene and psychological consequences post stroke in a Bahraini cohort.

BACKGROUND: The contribution of genetic factors such as the presence of ApoE allele e4 and its association with psychological consequences post stroke remains unknown within Middle-Eastern regions. This study examined the association of ApoE genotype with cognitive impairment and mood in stroke patients and compare with healthy older adults in Bahrain. METHOD: A prospective sample of n = 62 stroke patients (case group) and n = 53 healthy ageing individuals (control group) were eligible to participate in the study. A neuropsychological battery of cognitive assessments were conducted on all participants, and then stratified by cognitive function: no cognitive impairment, mild cognitive impairment and moderate to severe cognitive impairment. Anxiety and depression were assessed using the Hospital Anxiety and Depression Scale (HADS). RESULTS: Most frequent ApoE genotype was e2/e3 in case (44%) and control groups (63%). ApoE allele e3 had the highest frequency for both groups with all stroke patients presenting with this allele and 86% for the control group (χ2 = 12.14, p < .0001). Stroke patients' non-carriers for ApoE allele e4 performed better on all cognitive measures but differences were not statistically significant (ns). Carriers of ApoE allele e2 in both groups had less mood symptoms compared to non-carriers. DISCUSSION: ApoE genotype e3/e4 and e4/e4 was low in this Bahraini cohort explaining why there may been no significant associations found for this genotype variant with cognitive impairment. Further investigation of cognitive impairment and mood dysregulation with the different variants of the ApoE gene in general ageing and stroke populations is required from different ethno-cultural groups and geographical regions globally.

Endemic goitre and hypothyroidism in an adult female patient dependent on total parenteral nutrition.

We present the case of a thirty-year-old female patient who was referred to the endocrinology team with an enlarging goitre and biochemical hypothyroidism. She had been dependent on total parenteral nutrition for the previous six years as a result of intestinal failure thought to be caused by possible underlying mitochondrial disease. The patient also suffers from a Desmin myopathy, and at present, the exact aetiology behind her intestinal failure is not certain. The goitre was smooth and had been enlarging slowly over the previous few months. Thyroid peroxidase antibodies were found to be within normal range. Further analysis of the case showed that twelve months earlier the patients total parenteral nutrition (TPN) feed had been altered as a result of manganese toxicity. The current feeding regimen did not contain a trace element additive which had previously supplied iodine supplementation. A little detective work established that iodine content to the TPN had been reduced, the trace element additive (Additrace) was recommenced providing 1 µmol of iodine per day, equating to 130 µg of iodine. Following this change, thyroid-stimulating hormone levels returned to normal and the goitre quickly reduced in size. We present a rare case of endemic goitre and hypothyroidism in a patient receiving inadequate iodine supplementation through total parenteral nutrition. LEARNING POINTS: Endemic goitre and hypothyroidism secondary to iodine deficiency are rare in the developed world. However, the diagnosis should be considered in the setting of a diffuse goitre and negative thyroid antibodies.Although rare, endemic goitre should be considered in patients who present with hypothyroidism and who are dependent on total parenteral nutrition.Treatment with levothyroxine is not required in endemic goitre as thyroid function tests generally normalise with the addition of iodine to the diet/total parenteral nutrition regimen.Iodine supplementation at a level recommended by the European Society for Clinical Nutrition and Metabolism (ESPEN) was observed to quickly normalise this patient's thyroid function tests.

Prevention and Management of Radiation-induced Late Gastrointestinal Toxicity.

In the UK, about 90,000 cancer survivors will suffer from pelvic radiation disease (PRD) due to their curative treatment including radiotherapy. The National Cancer Survivorship Initiative aims to improve the understanding and management of PRD by the oncology community. This overview covers the prevention, investigation and treatment for late radiation-induced gastrointestinal symptoms in PRD. Multiple pharmacological and nutritional interventions have been studied, as prophylaxis for acute gastrointestinal toxicity (aiming to prevent late consequential effects), although predominantly only small randomised controlled trials have been conducted. These have produced mixed results, although promising signals for some agents have been observed. Evidence for the pharmacological prevention of late gastrointestinal toxicity is scarce. Even fewer randomised controlled trials have investigated the late gastrointestinal toxicity profile of advanced radiotherapy technologies. There are nationally agreed algorithms for the investigation and management of PRD, but a lack of awareness means patients still do not get referred appropriately. This overview outlines the management of radiation proctopathy and diarrhoea, and signposts other accessible resources. Finally, we provide recommendations for the management of late gastrointestinal symptoms in PRD and research in this field, especially the need for high-quality clinical trials.

Baltes' SOC model of successful ageing as a potential framework for stroke rehabilitation.

AIM: The aim of this paper is to explore approaches used to address some stroke rehabilitation interventions and to examine the potential use of one of the life-span theories called the Baltes' model of selective optimisation with compensation (SOC) as a potential framework. KEY FINDINGS AND IMPLICATIONS: Some of the key considerations for a stroke rehabilitation intervention framework are highlighted including accommodating for the life management changes post stroke, alterations in self-regulation, acknowledge losses and focusing on a person-centred approach for transition from acute rehabilitation to the home or community setting. The Baltes' SOC model is then described in terms of these considerations for a stroke rehabilitation intervention framework. CONCLUSIONS AND RECOMMENDATIONS: The Baltes' SOC model may offer further insights, including ageing considerations, for stroke rehabilitation approaches and interventions. It has potential to facilitate some of the necessary complexities of adjustment required in stroke rehabilitation. However, further development in terms of empirical support is required for using the model as a framework to structure stroke rehabilitation intervention. Implications for Rehabilitation There is a scarcity of theoretical frameworks that can facilitate and be inclusive for all the necessary complexities of adjustment, required in stroke rehabilitation. In addition to motor recovery post stroke, rehabilitation intervention frameworks should be goal orientated; address self-regulatory processes; be person-centred and use a common language for goal planning, setting and attainment. The Baltes' SOC model is one such framework that may address some of the considerations for stroke rehabilitation, including motor recovery and other life management aspects.

Health professionals' adherence to stroke clinical guidelines: a review of the literature.

BACKGROUND: The process of implementation of clinical guidelines i.e. getting guidelines into practice has been extensively reviewed and meta-reviewed from a generic perspective. However, in relation to stroke care, there has been no review of these studies to date, although implementing stroke clinical guidelines is a topic of great interest within the stroke literature. This review aims to identify stroke studies that have addressed adherence to generic and specific stroke care clinical guidelines. METHOD: A computer search was conducted using PubMed, CINAHL, PsychINFO, Web of Science and the Cochrane Systematic Reviews databases. Search terms included those relevant to the implementation of stroke clinical guidelines. We assessed all studies retrieved against specific inclusion criteria and collated only those studies that emphasized adherence to stroke clinical guidelines. RESULTS: Eighty-eight articles were selected for further review from 153 articles retrieved. Of those, 27 were studies on adherence to stroke clinical guidelines and were included in this review - 16 were categorized as generic stroke guidelines and 11 were on specific aspects of stroke care. Each category was further divided into studies that assessed adherence to stroke guidelines only and those that intervened to improve adherence. Adherence was generally greater for studies that included an intervention. Specific stroke care guidelines were poorly adhered to compared to generic stroke guidelines but these studies were better at identifying organizational and team barriers to implementation. Most studies conducted audits of patient medical records and a limited number assessed health professionals' views or used a behavioural framework to assess adherence. DISCUSSION: Adherence to stroke guidelines varied in the studies reviewed. Given the evidence that implementation of clinical guidelines in stroke care leads to better quality of care and improved health outcomes for patients, there is a need to increase adherence behaviours of health professionals towards recommended guidelines, in particular for long term stroke care.

Comparison of glycopyrrolate and atropine in ameliorating the adverse effects of imidocarb dipropionate in horses.

REASONS FOR PERFORMING STUDY: Imidocarb, an effective treatment for piroplasmosis, may cause colic and diarrhoea in horses. Atropine and glycopyrrolate are anticholinergics that could reduce the adverse effects of imidocarb. However, atropine and glycopyrrolate inhibit gastrointestinal motility, potentially causing ileus and colic. OBJECTIVES: To compare glycopyrrolate and atropine in ameliorating the adverse effects of imidocarb dipropionate in horses and to determine the effect of combinations of these drugs on the gastrointestinal tract. METHODS: A blinded, randomised, crossover study was performed in 8 healthy horses. Each horse received 0.9% saline i.m and i.v. (CON), and imidocarb 2.4 mg/kg bwt i.m. with one of 3 treatments i.v.: 0.9% saline (IMI), atropine 0.02 mg/kg bwt (IMATROP) and glycopyrrolate 0.0025 mg/kg bwt (IMGLYCO). Clinical data, gastrointestinal motility via borborygmi and frequency of contractions in the duodenum, caecum and right dorsal colon assessed with transabdominal ultrasound, and faecal data were measured. RESULTS: After imidocarb/saline treatment colic and diarrhoea were noted in 3 and 4 horses, respectively, faecal production and defaecation were increased for 3 h and faecal water percentage for 6 h. Colic was noted after atropine treatment in 4 horses, borborygmi and frequency of right dorsal colon contractions were significantly decreased for 2 h 15 min, and faecal production was not significantly different from CON. After glycopyrrolate treatment, colic was seen in one horse, frequency of intestinal contractions and faecal data were not significantly different from CON, and borborygmi was significantly decreased from CON at 1 h 15 min. CONCLUSIONS: Results of this study suggest that glycopyrrolate is superior to atropine in ameliorating the adverse effects of imidocarb. POTENTIAL RELEVANCE: Glycopyrrolate could be administered with imidocarb in horses with piroplasmosis to reduce the adverse effects of imidocarb.

Mapping patients' experiences after stroke onto a patient-focused intervention framework.

BACKGROUND: Stroke patients' involvement in the rehabilitation process including decision making has made significant advances clinically over the past two decades. However, development of patient-focused interventions in stroke rehabilitation is a relatively under developed area of research. The aim of this study was to interpret the explanations that patients gave of their experience after stroke and how these may validate an already established patient-focused intervention framework - the Quest for quality and improved performance (QQUIP) (2006) that includes seven quality improvement goals. METHODS: A random purposive sample of eight stroke patients was interviewed between 3 and 6 months following discharge. Patients' reports of their experience after stroke were obtained using in-dept semi-structured interviews and analysed using Qualitative Content Analysis. RESULTS: Explanations given by patients included both positive and negative reports of the stroke experience. Regardless of consequences as a result of physical, psychological and social impairments, there were other life style disruptions that were reported by all patients such as taking new medication and adverse effects of these, experiencing increasing fatigue, difficulties with social activities and situations and having to make changes in health behaviours and lifestyle. Some of the core themes that emerged reflected the aims of QQUIP improvement goals that include improving health literacy, clinical decision-making, self-care, patient safety, access to health advice, care experience and service development. DISCUSSION: Further recommendations based on the findings from this study would be to consider using the QQUIP framework for developing intervention studies in stroke rehabilitation care that are person-centred. This framework provides a template that is equipped to address some of the main concerns that people have following the experience of stroke and also focuses on improving quality of care.

Adaptation to stroke using a model of successful aging.

The process of adaptation to the physical and psychosocial consequences after stroke is a major challenge for many individuals affected. The aim of this study was to examine if stroke patients within 1 month of admission (n = 153) and followed up at 1 year (n = 107) engage in selection, optimization, and compensation (SOC) adaptive strategies and the relationship of these strategies with functional ability, health-related quality of life (HRQOL) and depression 1 year later. Adaptive strategies were measured using a 15-item SOC questionnaire. Internal and external resources were assessed including recovery locus of control, stroke severity, and socio-demographics. Outcome measures were the Stroke Specific Quality of Life Questionnaire (SS-QoL), the Nottingham Extended Activities of Daily Living Scale and the Depression Subscale of the Hospital Anxiety and Depression Scale. Findings indicated that stroke patients engaged in the use of SOC strategies but the use of these strategies were not predictive of HRQOL, functional ability or depression 1 year after stroke. The use of SOC strategies were not age specific and were consistent over time, with the exception of the compensation subscale. Results indicate that SOC strategies may potentially be used in response to loss regulation after stroke and that an individual's initial HRQOL functional ability, levels of depression and socio-economic status that are important factors in determining outcome 1 year after stroke. A stroke-specific measure of SOC may be warranted in order to detect significant differences in determining outcomes for a stroke population.

The future developments in nutrition.

Malnutrition is both a cause and consequence of disease. It is imperative that evidence-based approaches to detect and treat malnutrition are embedded into routine practice; these can range from routine malnutrition screening, the safe and appropriate use of enteral feeding and managing more complex patients with intestinal failure. This article outlines service developments over the next 5 years that may enable all hospitals to achieve optimal standards of care for a malnourished patient and examines the role of developments in clinical nutrition over the next 5-10 years.

Costs of care for Crohn's disease following the introduction of infliximab: a single-centre UK experience.

BACKGROUND: Infliximab is effective for induction and maintenance of remission in patients with Crohn's disease. There are few data, however, examining effect of infliximab therapy on management costs of Crohn's disease. AIM: To assess Crohn's disease-related costs of care and resource use in a single-centre cohort of patients with Crohn's disease 12 months pre- and post-infliximab therapy. METHODS: Data on 100 consecutive patients receiving infliximab were collected. Crohn's disease-related resource use was collected 12 months pre- and post-infliximab. National Health Service reference costs were applied to these data and the total Crohn's disease-related health service costs per patient were calculated (£UK). The cost of infliximab therapy was not included in our analysis. RESULTS: Cost savings were demonstrated in all areas of Crohn's disease-related resource use following infliximab therapy. Mean total Crohn's disease-related cost reduction, 12 months following commencement of infliximab therapy, was £2750 per patient. Mean costs at 12 months post-infliximab in responders were lower than in nonresponders (£1656 vs. £3608, P = 0.02). The number of hospitalizations was reduced. Requirements for examination under anaesthesia were also significantly decreased. CONCLUSION: Infliximab use resulted in Crohn's disease-related cost savings and hospital resource use, although this was not sufficient to cover the cost of therapy.

Effect of mood symptoms on recovery one year after stroke.

BACKGROUND: Depression and anxiety are the most common mood symptoms and psychological consequences of stroke. This study aimed to examine the influence of acute depression and anxiety symptoms on functional recovery and health-related quality of life (HRQoL) one year after stroke. METHODS: At one month and one year after stroke, the prevalence and severity of depression and anxiety symptoms were examined in consecutively admitted patients, using the Hospital Anxiety and Depression Scale (HADS). Functional recovery was assessed using the Nottingham Extended Activities of Daily Living (NEADL) and HRQoL using the Stroke-Specific Quality of Life scale (SSQOL). RESULTS: In 107 patients, the prevalence of depression and anxiety symptoms was 35% at one month and 36% and 34%, respectively, at one year. Depression symptoms were significantly associated with functional ability (r = -0.19, p < 0.05) and HRQoL (r = -0.41, p < 0.001) at one year. Anxiety symptoms were significantly associated with HRQoL (r = -0.33, p < 0.001) only. Multivariate analyses indicated that both depression (ß = -0.33, p < 0.001) and anxiety (ß = -0.26, p < 0.01) symptoms explained some variance in HRQoL at one month and did not predict functional recovery or HRQoL at one year, after controlling for other independent variables such as stroke severity and pre-morbid conditions. DISCUSSION: Mood symptoms following acute stroke were associated with a poorer HRQoL one year later but only depression symptoms influenced functional recovery. Other clinical factors such as pre-morbid conditions may need to be taken into consideration when determining the effect of mood symptoms on stroke recovery.

Sources of stress and psychological morbidity among undergraduate physiotherapy students.

OBJECTIVES: Professional education can be a stressful experience for some individuals, and may impact negatively on emotional well-being and academic performance. Psychological morbidity and associated sources of stress have not been investigated extensively in physiotherapy students. This study explored sources of stress, psychological morbidity and possible associations between these variables in undergraduate physiotherapy students. DESIGN: A questionnaire-based survey. The Undergraduate Sources of Stress Questionnaire was used to identify sources of stress, and the General Health Questionnaire-12 (GHQ-12) was used to rate the prevalence of psychological morbidity, using a conservative GHQ threshold of 3 to 4 to determine probable 'cases'. Uni- and multivariate tests of correlation were used to analyse the data. SETTING: An Irish educational institution. PARTICIPANTS: One hundred and twenty-five physiotherapy undergraduate students. RESULTS: More than one-quarter of all students (27%) scored above the GHQ threshold, indicating probable psychological morbidity. This is higher than the level of psychological morbidity reported by the general population. Regression analysis showed that academic (beta=0.31, P<0.001) and personal (beta=0.50, P<0.001) sources of stress subscales were significant coefficients, explaining 48% of the variance in psychological morbidity after controlling for part-time employment and hours spent studying. Individual significant items from these subscales were stressful events (beta=0.24, P=0.004), mood (beta=0.43, P< or =0.001) and overall level of stress (beta=0.35, P< or =0.001). CONCLUSIONS: The results highlighted the emotional vulnerability of a significant proportion of physiotherapy students, with academic and personal issues being the greatest concern. While personal causes of stress such as stressful events and mood are more difficult to control, manipulation of curricular factors may have positive effects on academic sources of stress.

Nuchal crest avulsion fracture in 2 horses: a cause of headshaking.

The medical records of 2 Thoroughbred horses that developed headshaking after blunt trauma to the occipital region are reviewed. The history, signalment, clinical signs, diagnostic methods, diagnosis and treatment were recorded in each case. Both horses displayed headshaking, while one horse repeatedly lifted its upper lip and pawed excessively at the ground. In both horses, diagnostic imaging of the occipital region revealed avulsion fragments of the nuchal crest and a nuchal desmitis in association with hyperfibrinogenaemia. The presence of an avulsion fragment of the nuchal crest with associated nuchal desmitis should be considered in horses presenting with headshaking and may respond favourably to conservative therapy.

After-hours equine emergency admissions at a university referral hospital (1998-2007): causes and interventions.

Medical records of equine after-hours admissions from 1998 to 2007 are reviewed. Data extracted from the medical records included signalment, reason for admission, pre-admission treatment, clinical presentation, procedures performed, final diagnoses, complications occurring in hospital, length of stay and outcome. Eight hundred and twenty after-hours admissions were available of which 75% were classified as emergencies. Most horses originated from Gauteng province (82%), with Thoroughbred, Arabian, and Warmbloods representing 46%, 10% and 7% of horses. Horses had a median age of 7 years and were predominantly male (60%). Gastrointestinal (64%) and musculoskeletal (19%) disorders were the primary reasons for admission. Anti-inflammatories, sedation and antibiotics were given in 51%, 20% and 15% of cases respectively prior to referral. On admission, 23% of horses had surgical intervention. Intravenous catheterisation (64%), rectal examination (61%), nasogastric intubation (56%), abdominocentesis (33%) and ultrasonography (19%) were the procedures performed most frequently. Surgical and medical colics constituted 28% and 27% respectively of the overall diagnoses, while piroplasmosis was diagnosed in 5% of horses. Post-admission complications occurred in <2% of horses. The median length of stay was 4 days (95% CI: 1 to 21 days). Overall survival to discharge was 74%. This study demonstrates that the majority of after-hours equine admissions to a university referral hospital required medical intervention and were mostly due to gastrointestinal disorders. Information obtained from this study can be used in emergency referral planning.

Causes of gastrointestinal colic at an equine referral hospital in South Africa (1998-2007).

The most common causes of gastrointestinal colic at an equine referral hospital in South Africa were determined following retrieval of the medical records of horses admitted during a 10-year study period. The study included 935 horses of which 28% were admitted after hours. Most horses were Thoroughbreds (54%), male (57%), with a mean age of 8.2 years and originated from the Gauteng Province (81%). Heart rate (98%), mucous membrane colour (95%) and auscultation of the abdomen (91%) were the clinical data commonly obtained at admission. Packed cell volume, total serum protein and white cell count were recorded in 78%, 75% and 44% of horses respectively. Transrectal palpation (93%), nasogastric intubation (84%), intravenous catheterisation (74%) and abdominocentesis (53%) were the most frequently performed procedures. Medical intervention was performed in 558 horses (60%). The common causes of medical colic were impactions (39%), tympany (7%) and displacement of the large colon (6%). An exploratory laparotomy was performed in 331 horses (36%). The common causes of surgical colic were displacement (29%), impaction (22%) and small intestinal strangulating lesions (18%). Death occurred in 3% of horses, while euthanasia before medical intervention was performed in 4%. Overall, medical intervention was successful in 93% of horses and 67% in horses managed surgically. In conclusion, 55% of all the equine admissions responded to medical intervention and the recovery rate for horses receiving both medical and surgical intervention was comparable to that reported in other studies.
