Spiritual/religious coping and depressive symptoms in informal caregivers of hospitalized older adults

This aim of this study was assess whether positive and negative spiritual/religious coping (SRC) strategies are associated with depressive symptoms (DS) of informal caregiver (IC) of hospitalized older adults. A cross-sectional study was conducted among 98 IC of hospitalized older adults in the medical clinic of a Brazilian School Hospital. The functionality, Positive and Negative SRC strategies and DS were evaluated. The IC had high average use of SRC, with Positive SRC being more used than Negative SRC. In the unadjusted regression model, Positive and Negative SRC were associated with DS. However, when adjusted for confounding factors, only Negative SRC remained associated with DS. The IC had used their religious and spiritual beliefs as a way to cope with the stress that comes from caring for hospitalized older adults. Although the positive strategy use of these beliefs was more common, only the negative strategies were associated with a higher DS.     

A new biliary access technique for the long-term endoscopic management of intrahepatic stones

Intrahepatic stone disease poses a difficult postoperative management problem due to frequent stone recurrence. Most of the methods proposed for long-term access to the intrahepatic biliary tree require multiple sessions of additional, usually invasive, procedures. An alternative method for endoscopic long-term access to the intrahepatic ducts, represented by a side-to-side anastomosis between the isolated Roux-en-Y jejunal limb of the bilioenteric bypass and the duodenum (duodenojejunostomy), was used in eight patients with retained and/or recurrent stones after surgical treatment of intrahepatic stone disease. There were no short- or long-term complications or mortality associated with the duodenojejunostomy. Postoperative endoscopic access to the intrahepatic ducts was successfully achieved in five of six patients: one with stone recurrence, one with a left hepatic duct stricture and stone recurrence and one with known retained postoperative stones. In two patients, no stones were found at endoscopy. Side-to-side duodenojejunostomy may be useful in the long-term endoscopic management of recurrent intrahepatic biliary stone disease and should be indicated whenever a bilioenteric anastomosis is performed for the treatment of bilateral intrahepatic stone disease.

Survival of patients with malignant biliary stricture based on endoscopic brushing and on bilirubinemia

BACKGROUND: Pancreatic cancer and cholangiocarcinoma are the main causes of malignant biliary stricture. Both types of cancers have dismal survival rates, and treatment has little or no effect on prolonging the patients lives. Prognostic definition at initial endoscopic retrograde cholangiopancreatography is important to choose the most suitable management. AIM: To analyse endoscopic brushing and bilirubinemia importance in determination of the survival of patients with malignant biliary stricture. METHODS: Patients with biliary strictures diagnosed during endoscopic retrograde cholangiopancreatography were submitted to double brushing cytology. Serum samples were taken from all patients for bilirubinemia assay. Patients were followed to determine the final diagnosis and survival rates. RESULTS: A total of 50 patients with biliary stricture underwent endoscopic retrograde cholangiopancreatography (40 ultimately found to have a final diagnosis of malignant disease). Hyperbilirubinemia or cytology brushing positive for malignancy was related to a shorter survival rate. CONCLUSION: This research data demonstrate the possibility of determining the prognosis of patients with malignant biliary stricture using endoscopic brushing results and bilirubinemia levels.     

Long-term fluvastatin reduces the hazardous effect of renal impairment on four-year atherosclerotic outcomes (a LIPS substudy)

Mild renal impairment is an important risk factor for late cardiovascular complications. This substudy of the Lescol Intervention Prevention Study (LIPS) assessed the effect of fluvastatin on outcome of patients who had renal dysfunction and those who did not. Complete data for creatinine clearance calculation (Cockcroft-Gault formula) were available for 1,558 patients (92.9% of the LIPS population). Patients were randomized to fluvastatin or placebo after successful completion of a first percutaneous coronary intervention. Follow-up time was 3 to 4 years. The effect of baseline creatinine clearance on coronary atherosclerotic events (cardiac death, nonfatal myocardial infarction, and coronary reinterventions not related to restenosis) was evaluated. Baseline creatinine clearance (logarithmic transformation) was inversely associated with an incidence of adverse events among patients who received placebo (hazard ratio 0.99, 95% confidence interval 0.982 to 0.998, p = 0.01). However, no association was noted between creatinine clearance and the incidence of adverse events among patients who received fluvastatin (hazard ratio 1.0, 95% confidence interval 0.99 to 1.0, p = 0.63). No further deterioration in creatinine clearance was observed during follow-up, regardless of baseline renal function or allocated treatment. Occurrence of adverse events was not related to changes in renal function during follow-up. Fluvastatin therapy markedly decreased the risk of coronary atherosclerotic events after percutaneous intervention in patients who had lower values of creatinine clearance at baseline. The benefit of fluvastatin was unrelated to any effect on renal function.     

Intestinal helminth infestation is associated with increased bronchial responsiveness in children

Non-atopic asthma is the predominant phenotype in non-affluent parts of Latin America. We recently reported that infestation with Ascaris lumbricoides increased the risk of non-atopic asthma in less affluent areas of Brazil but the mechanism is unclear. The present study was conducted to determine whether helminth infestation is associated with heightened bronchial responsiveness (BHR), a common finding in asthma. A random sample of 50 asthmatic and 50 non-asthmatic controls (mean age 10.1 years) were selected from a larger cohort (n = 1,011) without knowledge of their helminth infestation status. Three stool samples were collected from each child on different days and each sample was analyzed by the Kato-Katz method for quantitative determination of helminth eggs. Bronchial provocation tests were performed with inhaled 4.5% hypertonic saline using the ISAAC Phase II standardized protocol. There was no difference between the prevalence of positive BHR in the asthmatics (20.4%) compared with the controls (14.6%) (P = 1.0). Helminth infestation was detected in 24.0% of children, with A. lumbricoides being the most common. Children with high load infestation (>or=100 eggs/g) were five times more likely to have BHR than children with low load or no infestation. Despite the small sample size the results of the present study suggest that the link between high load helminth infestation and non-atopic asthma may be mediated via heightened bronchial responsiveness, possibly due to an inflammatory response to the pulmonary phase of the helminth life cycle.     

Pancreatic carcinomas smaller than 3.0 cm: endosonography (EUS) in diagnosis, staging and prediction of resectability

BackgroundThe size of a pancreatic carcinoma determines prognosis and resection. The aim of this study was to review our clinical experience with endoscopic ultrasound (EUS) in diagnosing and staging pancreatic tumours <3.0 in diameter.MethodsFrom February 1997 to October 2000 medical records and results of abdominal ultrasound (US), spiral computed tomography (CT) and EUS with fine-needle aspiration biopsy (FNA) were reviewed in 17 patients operated for histologically proven pancreatic adenocarcinoma measuring ≤ 3.0 cm in diameter. The mean age of the patients was 64 years (range 42–76 years).ResultsUS identified a pancreatic lesion in 11/17 (65%) patients. Spiral CT showed a total of 16/17 (94%) patients with a lesion. EUS identified pancreatic tumour in all patients (100%), and tissue was obtained from 15/17 patients (88%). Mean tumour size was 2.5 cm (range 0.8–3.0 cm). EUS accuracy in evaluating the portal vessels was 78%, superior mesenteric artery 100%, tumour stage (T) 88%, isolated node stage (N) 65% and combined TN staging was 53%. Regarding resectability, EUS sensitivity was 88%, specificity 89%, negative predictive value 89%, positive predictive value 88% and accuracy 88%. Besides cytological material, EUS-FNA histological diagnosis was possible in 12/17 patients (71%). There was only one case of mild post-procedure acute pancreatitis.ConclusionEUS-FNA is safe and has high diagnostic (100%) and local staging (88%) accuracy in pancreatic cancers <3.0 cm in diameter.
