RESUMEN
BACKGROUND AND METHODS: Pancreatico-duodenectomy (PD) carries significant morbidity and mortality, with very few modifiable risk factors. Radiological evidence of sarcopenia is associated with poor outcomes. This retrospective study aimed to analyse the relationship between easy-to-use bedside nutritional assessment techniques and radiological markers of muscle loss to identify those patients most likely to benefit from prehabilitation. RESULTS: Data were available in 184 consecutive patients undergoing PD. Malnutrition was present in 33-71%, and 48% had a high visceral fat-to-skeletal muscle ratio, suggestive of sarcopenic obesity (SO). Surgical risk was higher in patients with obesity (OR 1.07, 95%CI 1.01-1.14, p = 0.031), and length of stay was 5 days longer in those with SO (p = 0.006). There was no correlation between skeletal muscle and malnutrition using percentage weight loss or the malnutrition universal screening tool (MUST), but a weak correlation between the highest hand grip strength (HGS; 0.468, p < 0.001) and the Global Leadership in Malnutrition (GLIM) criteria (-0.379, p < 0.001). CONCLUSIONS: Nutritional assessment tools give widely variable results. Further research is needed to identify patients at significant nutritional risk prior to PD. In the meantime, those with malnutrition (according to the GLIM criteria), obesity or low HGS should be referred to prehabilitation.

AIMS: Treatment of pancreatic exocrine insufficiency (PEI) following pancreatoduodenectomy (PD) improves quality of life, clinical outcomes, and survival. However, diagnosing PEI following PD is challenging owing to the difficulties with current tests and often non-specific symptoms. This work aims to quantify the true rate of long-term PEI in patients following a PD. METHODS: Patients underwent a PEI screen approximately one to two years following PD for oncologic indication, including the 13C Mixed triglyceride breath test (13CMTGT), faecal elastase 1 (FE-1) and the PEI Questionnaire (PEI-Q). Four reviewers with expertise in PEI reviewed the results blinded to other decisions to classify PEI status; disagreements were resolved on consensus. RESULTS: 26 patients were recruited. Of those with valid test results, these were indicative of PEI based on pre-specified thresholds for 60 % (15/25) for the 13CMTGT, 82 % (18/22) for FE-1, and 88 % (22/25) for the PEI-Q. After discussion between reviewers, the consensus PEI prevalence was 81 % (95 % CI: 61-93 %; 21/26), with 50 % (N = 13) classified as having severe, 23 % (N = 6) moderate, and 8 % (N = 2) mild PEI. DISCUSSION: Since no ideal test exists for PEI, this collation of diagnostic modalities and blinded expert review was designed to ascertain the true rate of long-term PEI following PD. This required our cohort to survive a year, travel to hospital, and undergo a period of starvation and PERT hold, and therefore there is likely to be recruitment bias towards fitter, younger patients with less aggressive pathology. Despite this, over 80 % were deemed to have PEI, with over 90 % of these being considered moderate or severe.

The COVID-19 pandemic presented clinical and logistical challenges in the delivery of adequate nutrition in the critical care setting. The use of neuromuscular-blocking drugs, presence of maxilla-facial oedema, strict infection control procedures, and patients placed in a prone position complicated feeding tube placement. We audited the outcomes of dietitian-led naso-jejunal tube (NJT) insertions using the IRIS® (Kangaroo, USA) device, before and during the COVID-19 pandemic. NJT placement was successful in 78% of all cases (n = 50), and 87% of COVID-19 cases. Anaesthetic support was only required in COVID-19 patients (53%). NJT placement using IRIS was more difficult but achievable in patients with COVID-19.
RESUMEN
Pancreatico-duodenectomy (PD) includes resection of the duodenum and use of the proximal jejunum in a blind loop, thus reducing the absorptive capacity for vitamins and minerals. Several studies have analysed the frequency of micronutrient deficiencies, but there is a paucity of data on those taking routine supplements. A retrospective review of medical notes was undertaken on 548 patients under long-term follow-up following PD in a tertiary hepato-pancreatico-biliary centre. Data were available on 205 patients from 1-14 years following PD, and deficiencies were identified as follows: vitamin A (3%), vitamin D (46%), vitamin E (2%), iron (42%), iron-deficiency anaemia (21%), selenium (3%), magnesium (6%), copper (1%), and zinc (44%). Elevated parathyroid hormone was present in 11% of cases. There was no significant difference over time (p > 0.05). Routine supplementation with a vitamin and mineral supplement did appear to reduce the incidence of biochemical deficiency in vitamin A, vitamin E, and selenium compared to published data. However, iron, vitamin D, and zinc deficiencies were prevalent despite supplementation and require surveillance.

Pancreatic ductal adenocarcinoma (PDAC) is an aggressive malignancy for which the mainstay of treatment is surgical resection, followed by adjuvant chemotherapy. Patients with PDAC are disproportionately affected by malnutrition, which increases the rate of perioperative morbidity and mortality, as well as reducing the chance of completing adjuvant chemotherapy. This review presents the current evidence for pre-, intra-, and post-operative strategies to improve the nutritional status of PDAC patients. Such preoperative strategies include accurate assessment of nutritional status, diagnosis and appropriate treatment of pancreatic exocrine insufficiency, and prehabilitation. Postoperative interventions include accurate monitoring of nutritional intake and proactive use of supplementary feeding methods, as required. There is early evidence to suggest that perioperative supplementation with immunonutrition and probiotics may be beneficial, but further study and understanding of the underlying mechanism of action are required.
RESUMEN
INTRODUCTION: Acute pancreatitis (AP) is a medical emergency that is common, poorly understood and carries a significant risk of death. The National Confidential Enquiry into Patient Outcome and Death (NCEPOD) undertook a comprehensive report into the current management of AP in the UK. The study aimed to provide a more detailed analysis of the findings related to nutritional assessment and support. METHODS: The data presented here were analysed from the core dataset used in the NCEPOD study. Adult patients admitted between January and June 2014 with a coded diagnosis of AP were included. A clinical and organisational questionnaire was used to collect data and submitted case notes subjected to peer review. Nutritional data, including assessment and provision of support, were analysed. RESULTS: One hundred and forty-seven out of 168 (87.5%) hospitals had a nutrition team in place. A screening nutritional assessment was performed in only 67.4% (368/546) of patients. Subsequent referral to a dietitian and nutrition team input occurred in 39% (201/521) and 25% (143/572) of patients, respectively. Supplemental nutrition was considered and used in 240/555 (43.2%) patients. Overall management of the patients' nutrition was considered adequate by the case reviewers in only 281/332 (85%) of cases and by the clinicians in 77% (421/555) of cases. CONCLUSIONS: Many patients do not receive adequate nutritional assessment and, in up to 23% of cases, nutritional intervention is not adequate. Pancreatic exocrine insufficiency is likely under recognised and undertreated. Nutritional strategies to support early intervention and to support clinicians outside of tertiary pancreatic centres are warranted.

INTRODUCTION: Pancreatic exocrine insufficiency is a finding in many conditions, predominantly affecting those with chronic pancreatitis, pancreatic cancer and acute necrotising pancreatitis. Patients with pancreatic exocrine insufficiency can experience gastrointestinal symptoms, maldigestion, malnutrition and adverse effects on quality of life and even survival.There is a need for readily accessible, pragmatic advice for healthcare professionals on the management of pancreatic exocrine insufficiency. METHODS AND ANALYSIS: A review of the literature was conducted by a multidisciplinary panel of experts in pancreatology, and recommendations for clinical practice were produced and the strength of the evidence graded. Consensus voting by 48 pancreatic specialists from across the UK took place at the 2019 Annual Meeting of the Pancreatic Society of Great Britain and Ireland annual scientific meeting. RESULTS: Recommendations for clinical practice in the diagnosis, initial management, patient education and long term follow up were developed. All recommendations achieved over 85% consensus and are included within these comprehensive guidelines.

Pancreatic exocrine insufficiency (PEI) frequently occurs secondary to exocrine pancreatic disease (e.g. chronic pancreatitis, cystic fibrosis, cancer) or pancreatic/gastrointestinal surgery, resulting in the maldigestion of nutrients and consequently malnutrition. Pancreatic enzyme replacement therapy (PERT) is the cornerstone of PEI management. Despite its clinical relevance, the diagnosis of PEI in clinical practice is challenging, as the current gold standard test is cumbersome, and alternatives have limited availability or accuracy. There is a need for accurate and easily applicable diagnostic modalities. We review the prevalence of clinical symptoms and changes in anthropometric measurements and laboratory nutritional markers indicative of malnutrition in patients with PEI, and the relevance of these findings in diagnosing PEI and monitoring PERT efficacy. Based on limited available evidence, assessment of clinical symptoms, body weight, body mass index and other anthropometric parameters are not sensitive methods for PEI diagnosis, owing to high variability and multiple confounding factors, but appear useful in monitoring PERT efficacy. Limited evidence precludes strong recommendations but suggests that serum levels of vitamin E, magnesium, and plasma proteins, notably retinol binding protein, albumin, and prealbumin, may have diagnostic utility in PEI. Studies show that assessment of changes in these and other nutritional parameters is helpful in monitoring PERT efficacy. Further research is needed to confirm the diagnostic accuracy of these parameters for PEI. Until such data are available, a nutritional evaluation including circulating vitamin E, magnesium, retinol binding protein, albumin, and prealbumin may be used to evaluate the probability of PEI in clinical practice when reliable pancreatic function tests are not available.

BACKGROUND/OBJECTIVES: Untreated pancreatic exocrine dysfunction is associated with poor quality of life and reduced survival, but is difficult to diagnose following pancreatic resection. Many factors including the extent of the surgery, the health of the residual pancreas and the type of reconstruction must be considered. Patients remain undertreated, and consequently there is much debate to whether or not pancreatic enzyme replacement therapy should be routinely prescribed following pancreatic resection. METHODS: A review of the literature was undertaken to establish the incidence of PEI and factors identifying treatment. RESULTS: Forty two to forty five percent of patients undergoing pancreatico-duodenectomy (PD) experience pancreatic exocrine insufficiency pre-operatively, whilst the post-operative incidence is 56-98% in PD, and 12-80% following distal and central pancreatectomy. CONCLUSIONS: Routine use of pancreatic enzyme replacement should be considered at a starting dose of 50 to 75,000 units lipase with meals and 25,000 to 50,000 units with snacks in this patient group. Patients who have had a central or distal pancreatectomy should be individually assessed for pancreatic exocrine insufficiency in the post operative period, with those undergoing extensive resection most likely to experience insufficiency. Patients who fail to respond to pancreatic enzyme replacement therapy should be referred to a specialist dietitian, be advised on dose adjustment, and undergo investigation to exclude other gastro-intestinal pathology, including small bowel bacterial overgrowth and bile acid malabsorption.

This paper presents findings from a quantitative study about alcohol-impaired drivers in Utah. The University of Utah's Social Research Institute conducted a retrospective case file evaluation about the adjudication and sanctioning phases associated with driving under the influence (DUI) to determine Utah's response to DUI crime from arrest forward. Although Utah driver's license and court systems are on the cutting edge of dealing with DUI offenders, we found a variety of limitations for analysis due to data collection and entry. Therefore, it is difficult to develop a thorough understanding about the process of dealing with DUI offenders and the effectiveness of court actions and treatments. The purpose of this paper is to provide recommendations about how to ensure more accurate data collection about impaired drivers.
