Prevalence and prognostic significance of depressive symptoms in a geriatric post-hip fracture assessment.

OBJECTIVES: To investigate the prevalence and prognostic significance of post-hip fracture depressive symptoms. METHODS: A naturalistic clinical cohort study. Data were collected on admission to hospital, geriatric assessment 4-6 months post-fracture and by telephone interview one-year post fracture. Depressive symptoms were assessed at the geriatric assessment using the 15-item Geriatric Depression Scale (GDS-15). Logistic regression analyses with multivariable models were conducted to examine the association of depressive symptoms with changes in mobility and living arrangements and Cox proportional hazards models for mortality between the geriatric assessment and one-year follow-up. RESULTS: Of the 1070 patients, 22% (n = 238) had mild and 6% (n = 67) moderate to severe depressive symptoms. Patients with depressive symptoms had poorer nutritional status at baseline, lower scores on the cognitive and physical performance tests and poorer functional abilities in the geriatric assessment than those without. No association was observed between depressive symptoms and any of the outcomes at one-year follow-up. Poor nutritional status and physical functioning remained significant prognostic indicators. CONCLUSION: Post-hip fracture depressive symptoms are common and deserve attention during post-hip fracture recovery and rehabilitation. Nonetheless, depressive symptoms have no impact on the change in mobility or living arrangements or mortality. These latter outcomes are mainly explained by poor nutritional status and functioning.

In-Hospital Delirium as a Prognostic Factor for New Cognitive Disorder in a 1-Year Post-Hip Fracture Follow-Up.

BACKGROUND: Older hip fracture patients are at high risk of delirium during acute hospital care. Pre-fracture dementia is known to increase the risk of in-hospital delirium. Data on the development of new cognitive disorders in patients with delirium are scarce. OBJECTIVE: The objective of this study is to evaluate the prognostic significance of in-hospital delirium on the development of new cognitive disorders in a 1-year follow-up in older hip fracture patients. MATERIAL AND METHODS: Data consisted of 476 hip fracture patients aged 65 years or more with no known cognitive disorder on admission. Delirium was assessed using the Confusion Assessment Method (CAM). Cognitive disorders were diagnosed following the national guidelines. Information on the new diagnoses of cognitive disorders (NDCD) at 1-year follow-up was elicited in a telephone interview and confirmed from the electronic patient files. Logistic regression analyses were conducted to examine the association of delirium with NDCDs. RESULTS: Of the 476 patients, 87 (18%) had delirium during hospital stay. Patients with delirium were older, they had poorer nutritional status, lower mobility level, and more supported living arrangements than did patients without delirium. At the 1-year time point, 205 (43%) had NDCDs or were strongly suspected of this. CAM result was statistically significantly associated with development of NDCD in multivariable-adjusted analysis (odds ratio [OR] 2.29; 95% confidence interval [CI]: 1.39-3.79). Also, poor nutritional status continued to be associated with NDCDs (multivariable-adjusted OR 1.58; 95% CI: 1.03-2.43). CONCLUSION: Delirium during hospitalization and poor nutritional status on admission are independent prognostic factors for development of subsequent cognitive disorders in older hip fracture patients.

Effect of pre-operative oral carbohydrate loading on recovery after day-case cholecystectomy: A randomised controlled trial.

BACKGROUND: Pre-operative carbohydrate loading has been shown to reduce pre-operative discomfort and postoperative nausea and vomiting in general surgical patients. Few studies have considered day-case surgery. OBJECTIVE: The aim of this prospective randomised study was to determine whether pre-operative carbohydrate loading enhanced recovery after day-case cholecystectomy. DESIGN: A randomised controlled trial. SETTING: Secondary care in a district general and a university hospital in Finland between 2013 and 2016. PATIENTS: A total of 113 patients American Society of Anesthesiologists physical status I or II aged 18 to 70 undergoing day-case cholecystectomy were included in the study. Exclusion criteria were bleeding or coagulation disorders, BMI more than 40 kg m, dementia, insulin-treated diabetes, migraine, Meniere's disease or a history of alcohol or drug abuse. INTERVENTION: The carbohydrate-rich drink group received oral carbohydrate (200 ml) 2 to 3 h before surgery, and the control (fasting) group fasted from midnight according to standard protocol. MAIN OUTCOME MEASURES: Visual analogue scales (VAS) were used to score six forms of discomfort: the need for analgesia and antiemetics, the time to drinking, eating and first mobilisation after surgery and the time to discharge. Any hospital re-admission was also recorded. RESULTS: The highest VAS scores were seen for mouth dryness and tiredness 2 h after surgery in the fasting group. There were no significant differences in any VAS scores between the study groups. No differences in time to mobilisation, need for pain or antiemetic medication or time to discharge were seen between the groups. CONCLUSION: Compared with overnight fasting, pre-operative carbohydrate loading did not significantly enhance peri-operative well being or recovery in patients undergoing day-case cholecystectomy.

Predictive value of the mini-nutritional assessment short form (MNA-SF) and nutritional risk screening (NRS2002) in hip fracture.

BACKGROUND/OBJECTIVES: To examine Mini-Nutritional Assessment short form (MNA-SF) and Nutritional Risk Screening 2002 (NRS2002) as prognostic indicators of postoperative complications, length of hospital stay (LOS), readmissions, mobility, living arrangements and mortality after hip fracture. SUBJECTS/METHODS: Population-based prospective data were collected on 265 consecutive hip fracture patients aged 65 and over. Nutritional status according to MNA-SF and NRS2002 was assessed on admission. Outcomes were postoperative complications, LOS, readmissions and mortality 1 and 4 months post fracture and changes in mobility level and living arrangements 4 months post fracture. RESULTS: At baseline, 18 (7%) patients were malnourished and 108 (41%) at risk of malnutrition according to MNA-SF. According to NRS2002, 11 (4%) patients were at severe risk and 56 (21%) patients at moderate risk of malnutrition. Only MNA-SF predicted mortality, LOS and readmissions. Both instruments proved ineffective in predicting changes in mobility level and living arrangements. CONCLUSIONS: MNA-SF is superior to NRS2002 in predicting short-term hip fracture outcomes.

Detection of Pancreatic Cancer by Urine Volatile Organic Compound Analysis.

BACKGROUND/AIM: Most pancreatic cancer patients are diagnosed at an advanced stage, since the diagnosis is demanding. Field asymmetric waveform ion mobility spectrometry (FAIMS) is a sensitive technique used for the detection of volatile organic compounds (VOC). We evaluated the ability of FAIMS to discriminate between pancreatic cancer and healthy controls from a urine sample. PATIENTS AND METHODS: For a proof-of-concept study in three Finnish hospitals, 68 patients with pancreatic cancer, 36 with acute pancreatitis, 18 with chronic pancreatitis, 8 with pancreatic pre-malign lesions and 52 healthy controls were prospectively recruited. Urine samples were collected at the time of diagnosis and stored at -70°C. The samples were subsequently measured with FAIMS. The data were processed with linear discriminant analysis and cross-validated with leave-one-out cross-validation. RESULTS: FAIMS distinguished pancreatic cancer from controls with a sensitivity of 79% and specificity of 79%. CONCLUSION: As a non-invasive and rapid urine test, FAIMS can discriminate patients with pancreatic cancer from healthy controls.

Comparison of the Mini-Nutritional Assessment short and long form and serum albumin as prognostic indicators of hip fracture outcomes.

INTRODUCTION: Malnutrition is common among older hip fracture patients and associated with adverse outcomes. We examined Mini Nutritional Assessment short (MNA-SF) and long form (MNA-LF) and serum albumin as prognostic indicators of mobility, living arrangements and mortality after hip fracture. METHODS: Population-based prospective data were collected on 594 hip fracture patients aged 65 and over. MNA-SF, MNA-LF and serum albumin were assessed on admission. Outcomes were poorer mobility; transfer to more assisted living accommodation and mortality one month, four months and one year post fracture. Logistic regression analyses for mobility and living arrangements with odds ratios (OR) and Cox proportional hazards model for mortality with hazard ratios (HR) and 95% confidence intervals (CI) were used, adjusted for age, gender, ASA grade and fracture type. RESULTS: All measures predicted mortality at all time-points. Risk of malnutrition and malnutrition measured by MNA-LF predicted mobility and living arrangements within four months of hip fracture. At one year, risk of malnutrition predicted mobility and malnutrition predicted living arrangements, when measured by MNA-LF. Malnutrition, but not risk thereof, measured by MNA-SF predicted living arrangements at all time-points. None of the measures predicted one-month mobility. CONCLUSIONS: All measures were strong indicators of short- and long-term mortality after hip fracture. MNA-LF was superior in predicting mobility and living arrangements, particularly at four months. All measures were relatively poor in predicting short-term outcomes of mobility and living arrangements.

Can Laparoscopic Cholecystectomy Prevent Recurrent Idiopathic Acute Pancreatitis?: A Prospective Randomized Multicenter Trial.

OBJECTIVE: The aim of the present trial was to ascertain whether laparoscopic cholecystectomy (LCC) can prevent recurrent attacks of idiopathic acute pancreatitis (IAP). SUMMARY: Up to 50% to 75% of IAP may be due to microlithiasis, which is undetectable by conventional imaging methods. METHODS: This randomized, prospective trial included 85 patients (39 in the LCC and 46 in the control group) in 8 hospitals in Finland. We included adult patients (over 18 years) with their first attack of IAP. The diagnosis of IAP was based on the exclusion of common etiological reasons for acute pancreatitis (AP), whereafter the patients were randomized into conservative watchful waiting (controls) or LCC group. The primary end point was the number of patients with recurrent AP during the follow-up. All recurrent attacks of AP after an initial IAP episode were registered. RESULTS: During a median follow-up of 36 (5-58) months, the recurrence of IAP was significantly higher in the control group than in LCC group (14/46 vs. 4/39, P = 0.016), as was also the number of recurrences (23/46 vs. 8/39, P = 0.003). In the subgroup of patients with at least 24 months' follow-up, the recurrence was still higher among controls (14/37 vs. 4/35, P = 0.008). In patients with normal liver function, recurrence was also significantly higher in the control than in the LCC group (13/46 vs. 4/39, P = 0.026). During surgery, 23/39 (59%) of the gallbladders were found to contain biliary stones or sludge. CONCLUSIONS: LCC can effectively prevent the recurrence of IAP when all other possible etiologies of pancreatitis are carefully excluded. A total of 5 patients needed to be treated (NNT-value) to prevent 1 IAP.

Effect of preoperative intravenous carbohydrate loading on preoperative discomfort in elective surgery patients.

BACKGROUND AND OBJECTIVE: We studied the effect of three different fasting protocols on preoperative discomfort and glucose and insulin levels. METHODS: Two hundred and ten ASA I-III patients undergoing general or gastrointestinal surgery were randomly assigned to three groups: overnight intravenous 5% glucose infusion (1000 ml), carbohydrate-rich drink (400 ml) at 6-7 a.m., or overnight fasting. The subjective feelings of thirst, hunger, mouth dryness, weakness, tiredness, anxiety, headache and pain of each patient were questioned preoperatively using a visual analogue scale. Serum glucose and insulin levels were measured at predetermined time points preoperatively. RESULTS: During the waiting period before surgery, the carbohydrate-rich drink group was less hungry than the fasting group (P = 0.011). No other differences were seen in visual analogue scale scores among the study groups. Trend analysis showed increasing thirst, mouth dryness and anxiety in the intravenous glucose group (P < 0.05). The carbohydrate-rich drink group experienced decreasing thirst but increasing hunger and mouth dryness (P < 0.05). In the fasting group, thirst, hunger, mouth dryness, weakness, tiredness and anxiety increased (P < 0.05). Both intravenous and oral carbohydrate caused a significant increase in glucose and insulin levels. CONCLUSION: Intravenous glucose infusion does not decrease the sense of thirst and hunger as effectively as a carbohydrate-rich drink but does alleviate the feelings of weakness and tiredness compared with fasting.
