[The association of job satisfaction with self-reported burnout among urologists with migration background working at German hospitals : Results of the EUTAKD study]. / Die Assoziation von beruflicher Zufriedenheit mit selbstberichtetem Burnout bei Urologen und Urologinnen mit Migrationshintergrund tätig an deutschen Kliniken : Ergebnisse der EUTAKD-Studie.

INTRODUCTION: Urologists with a migration background currently provide patient care in German hospitals. Study results on job satisfaction and burnout of this important professional group have not been available so far. MATERIALS AND METHODS: Between August and October 2020, a questionnaire (SurveyMonkey® with 101 items) was conducted among urologists with migration background working in German hospitals regarding professional satisfaction and a validated survey of burnout (Maslach Burnout Inventory), among others. The subject of this work was the association of job satisfaction with the critical thresholds of burnout in the domains of emotional exhaustion (EE), depersonalization (DP), and low personal accomplishment (PA). RESULTS: For this work, 68 questionnaires could be completely analyzed. Study participants were dominantly male (90%), between 30 and 39 years of age (69%), married (72%), and working full-time (94%). Above critical thresholds of high burnout in the EE, DP, and PA domains were 27.9% (n = 19), 35.3% (n = 24), and 73.5% (n = 50) of study participants. A sum score was formed from five of a total of 39 satisfaction items, which independently predicted the EE and DP endpoints and a combined EE and DP endpoint in well-adjusted regression models. For each individual score of the sum score (range 5-25 points), the probability of a critical burnout is reduced by a relative 57% (EE), 25% (DP), and 34% (combined endpoint). In contrast, permanent employment contract, the clinic position as senior physician or chief physician, working full-time, and a married marital status significantly reduced the critical PA domain. CONCLUSION: Several dimensions of professional satisfaction were identified, the improvement of which could contribute to a decrease in burnout among urologists with a migrant background. Future intervention studies aimed at improving job satisfaction must follow.

Selective regulation of p38ß protein and signaling by integrin-linked kinase mediates bladder cancer cell migration.

Integrin-linked kinase (ILK) and p38(MAPK) are protein kinases that transduce extracellular signals regulating cell migration and actin cytoskeletal organization. ILK-dependent regulation of p38(MAPK) is critical for mammalian kidney development and in smooth muscle cell migration, however, specific p38 isoforms has not been previously examined in ILK-regulated responses. Signaling by ILK and p38(MAPK) is often dysregulated in bladder cancer, and here we report a strong positive correlation between protein levels of ILK and p38ß, which is the predominant isoform found in bladder cancer cells, as well as in patient-matched normal bladder and tumor samples. Knockdown by RNA interference of either p38ß or ILK disrupts serum-induced, Rac1-dependent migration and actin cytoskeletal organization in bladder cancer cells. Surprisingly, ILK knockdown causes the selective reduction in p38ß cellular protein level, without inhibiting p38ß messenger RNA (mRNA) expression. The loss of p38ß protein in ILK-depleted cells is partially rescued by the 26S proteasomal inhibitor MG132. Using co-precipitation and bimolecular fluorescent complementation assays, we find that ILK selectively forms cytoplasmic complexes with p38ß. In situ proximity ligation assays further demonstrate that serum-stimulated assembly of endogenous ILK-p38ß complexes is sensitive to QLT-0267, a small molecule ILK kinase inhibitor. Finally, inhibition of ILK reduces the amplitude and period of serum-induced activation of heat shock protein 27 (Hsp27), a target of p38ß implicated in actin cytoskeletal reorganization. Our work identifies Hsp27 as a novel target of ILK-p38ß signaling complexes, playing a key role in bladder cancer cell migration.

Activins and inhibins in mammalian testis development: new models, new insights.

The discovery of activin and inhibins as modulators of the hypothalamic-pituitary-gonadal axis has set the foundation for understanding their central importance to many facets of development and disease. This review contains an overview of the processes and cell types that are central to testis development and spermatogenesis and then provides an update focussed on information gathered over the past five years to address new concepts about how these proteins function to control testis development in fetal and juvenile life. Current knowledge about the interactive nature of the transforming growth factor-ß (TGFß) superfamily signalling network is applied to recent findings about activins and inhibins in the testis. Information about the regulated synthesis of signalling components and signalling regulators in the testis is integrated with new concepts that demonstrate their functional significance. The importance of activin bioactivity levels or dosage in controlling balanced growth of spermatogonial cells and their niche at different stages of testis development is highlighted.

Abdominal pain and ECG alteration: a simple diagnosis?

Acute pancreatitis is a disease initially located into the pancreas that may become a systemic disease involving organs distant from the pancreas. All organs may be involved during an acute attack of pancreatitis: lungs, kidney, heart, liver, brain. The differential is sometime difficult because acute pancreatitis may sometimes mimic an acute coronary syndrome. We report a case of a 36-year-old man who was admitted to Emergency Room for persistent epigastric pain. Serial electrocardiograms (ECG) showed signs of acute myocardial infarction. However, a coronary angiogram demonstrated no coronary artery disease, and serum troponin was undetectable. Later, serum pancreatic enzyme levels were elevated and an ultrasonography scan of the abdomen was consistent with pancreatitis. Physicians should keep in mind the possibility of an attack of pancreatitis in a patient with abdominal pain and ECG modifications who is a heavy drinker.

Relapses of biliary acute pancreatitis in patients with previous attack of biliary pancreatitis and gallbladder in situ.

AIM: To evaluate relapse of acute pancreatitis in patients with biliary pancreatitis in whom coexisting diseases or patient refusal have excluded cholecystectomy. PATIENTS AND METHODS: Forty-seven patients presenting a first episode of biliary acute pancreatitis underwent urgent endoscopic retrograde cholangiopancreatography (ERCP) with endoscopic sphincterotomy (ES). RESULTS: ERCP with ES was successful in all but one patient (97.8%) who was then cholecystectomised. Complications related to the endoscopic procedure were reported in five patients (10.6%). During the follow-up period (median time 12 months; range 1-84 months), 10 patients (21%) suffered from biliary complications. Three patients (6.4%), all with lithiasis of the gallbladder, had relapses of acute pancreatitis, two of them within 2 months of the previous episode, and one about a year later after ingestion of a rich meal and alcoholic beverages. The first two were cholecystectomised. Two patients died during the follow-up period from unrelated diseases. CONCLUSIONS: In subjects who are at high risk for anaesthesia, endoscopic procedures may be utilised.

Time-course and clinical value of the urine trypsinogen-2 dipstick test in acute pancreatitis.

OBJECTIVE: Urine trypsinogen-2 has been suggested as a marker of damage due to acute pancreatitis. Our aim was to assess the time-course and the clinical value of this test in acute pancreatitis. METHODS: A urine trypsinogen-2 dipstick test was performed on 30 patients with acute pancreatitis upon admission to the emergency room, as well as on 30 patients with non-pancreatic acute abdominal pain, and in 30 healthy subjects. RESULTS: In 53.3% of the patients with acute pancreatitis the dipstick test showed abnormal urine trypsinogen-2 whereas this test gave negative results in all patients with non-pancreatic acute abdomen and in all healthy subjects. Patients with severe acute pancreatitis had a frequency of abnormal results of urine trypsinogen-2 (8/9, 88.9%; 95% CI, 51.8-99.7%) significantly higher (P = 0.031) than those with the mild disease (8/21, 38.1%; 95% CI, 18.1 -61.6%), while no significant differences were found in the urine trypsinogen-2 results between patients with biliary acute pancreatitis and those with non-biliary acute pancreatitis. Regarding the time-course of urine trypsinogen-2, there were no significant differences during the three days of the study. CONCLUSIONS: The specificity of urine trypsinogen-2 in the diagnosis of acute pancreatitis is good however its sensitivity is low.

Serum amyloid A, procalcitonin, and C-reactive protein in early assessment of severity of acute pancreatitis.

Amyloid A (SAA) and procalcitonin (PCT) have been reported as useful indicators of inflammation. Our aim was to assess the utility of SAA and PCT in establishing the severity of acute pancreatitis in comparison to C-reactive protein (CRP): Thirty-one patients with acute pancreatitis enrolled within 24 hr from the onset of pain and 31 healthy subjects were studied. Nineteen patients had mild acute pancreatitis, and 12 had severe pancreatitis. Serum SAA, PCT, and CRP were measured in all subjects at admission and, in acute pancreatitis patients, during the following five days. Patients with acute pancreatitis had serum concentrations of SAA, PCT, and CRP significantly higher (P < 0.001) than those of healthy subjects during the entire study period. Using cutoff values ranging from 240 to 250 mg/liter for SAA, from 0.252 to 0.255 ng/ml for PCT, and from 12.8 to 12.9 mg/dl for CRP, the sensitivity (calculated on patients with severe pancreatitis), the specificity (calculated on patients with mild pancreatitis), and the efficiency (calculated as the percentage of correct classifications) were 76.8%, 69.3%, and 72.4% for SAA; 21.7%, 83.2%, and 58.2% for PCT; and 60.9%, 89.1%, and 77.6% for CRP. In conclusion, the sensitivity of SAA is significantly higher than that of PCT and CRP in assessing the severity of pancreatitis, whereas PCT and CRP had a specificity significantly higher than SAA. The accuracy and efficiency were similar for SAA and CRP, and both these markers had an accuracy and efficiency significantly higher than those of PCT.

Simultaneous serum assays of lipase and interleukin-6 for early diagnosis and prognosis of acute pancreatitis.

BACKGROUND: There are no systems for the rapid diagnosis and prognosis of acute pancreatitis in the Emergency Department. Our aim was to evaluate whether the combined use of serum lipase and interleukin-6 or serum lipase and C-reactive protein is able to simultaneously establish both the diagnosis and the prognosis of acute pancreatitis. METHODS: Eighty patients with acute abdomen were studied on admission to the Emergency Room. Forty patients had nonpancreatic acute abdomen, and 40 had acute pancreatitis (25 had mild acute pancreatitis and 15 had severe pancreatitis). Forty healthy subjects comparable for sex and age were also studied as controls. Lipase, interleukin-6, and C-reactive protein were determined on serum in all subjects. RESULTS: Using lipase to discriminate between patients with nonpancreatic acute abdomen and patients with acute pancreatitis (cutoff values ranging from 419 to 520 U/L), one patient with acute pancreatitis was not identified correctly. To discriminate between patients with severe acute pancreatitis and those with mild pancreatitis in the remaining 39 patients, interleukin-6 (cutoff value, <3.7 microgram/L) had a sensitivity of 100% (15 of 15) and a specificity of 83% (20 of 24); 75 of 80 (94%) patients were classified correctly. C-reactive protein (cutoff values ranging from 6 to 7 mg/L) showed a lower prognostic efficiency than interleukin-6: sensitivity of 87% (13 of 15) and specificity of 46% (11 of 24). Sixty-four of 80 patients (80%) were classified correctly. The area under the ROC curve for interleukin-6 (0.911 +/- 0.049) was significantly (P = 0.013) greater than that for C-reactive protein (0.685 +/- 0.090). CONCLUSION: The combined use of serum lipase and interleukin-6 is useful in simultaneously establishing both the diagnosis and the prognosis of acute pancreatitis.

Ultrasonographic evaluation of the common bile duct in biliary acute pancreatitis patients: comparison with endoscopic retrograde cholangiopancreatography.

We compared the morphologic findings of the common bile duct by ultrasonography and endoscopic retrograde cholangiopancreatography in patients with biliary acute pancreatitis. Forty-five patients were studied. The diagnosis of acute pancreatitis was based on the presence of characteristic abdominal pain associated with an elevation of serum amylase and lipase concentrations. All patients underwent ultrasonography and subsequently urgent endoscopic retrograde cholangiopancreatography and eventually endoscopic sphincterotomy. Ultrasonography showed gallstones in 33 patients and sludge of the gallbladder in seven patients. In the common bile duct, lithiasis was found in two patients and sludge in 25. Endoscopic retrograde cholangiopancreatography showed choledocolithiasis in eight patients and sludge of the common bile duct in 32. In 27 cases (60%) concordance occurred between ultrasonographic and endoscopic retrograde cholangiopancreatographic detection of lithiasis or sludge of the common bile duct. The average diameter of the common bile duct determined by sonography was significantly smaller (P < 0.001) than that obtained by endoscopic retrograde cholangiopancreatography. The evaluation of this parameter indicated that a good correlation existed between the values obtained with the two techniques (r(s) = 0.765, P < 0.001). Both ultrasonography and endoscopic retrograde cholangiopancreatography can provide reliable measurements of the common bile duct diameter. Ultrasonography is the technique of choice in the initial investigation of patients with biliary acute pancreatitis.

The use of the peripheral leukocyte count and chest X-rays in early assessment of the severity of acute pancreatitis in comparison with the Ranson score system.

BACKGROUND: To evaluate the efficacy of the peripheral leukocyte count and chest X-rays as an index which could be used in the early assessment of the severity of acute pancreatitis in an Emergency Room. METHODS: We prospectively evaluated the peripheral leukocyte count and the findings of chest X-rays in 181 consecutive patients (102 males, 79 females, mean age 61 years, range 16-97) who were admitted to our Emergency Department with acute pancreatitis. One hundred twenty six patients had mild pancreatitis and 55 had severe pancreatitis. The peripheral leukocyte count and the chest X-rays were evaluated in all patients upon admission. The Ranson criteria were also assessed. RESULTS: Using a cut off value of 13,000/mm3, 45% of the patients with severe pancreatitis and 17% of those with mild acute pancreatitis had a peripheral leukocyte count greater than 13,000/mm3. Pleural or pulmonary alterations observed on chest X-ray were found in 66% of patients with severe pancreatitis and in 2% of those with mild acute pancreatitis. A peripheral leukocyte count greater than 13,000/mm3 and/or pleural or pulmonary alterations present on chest X-ray were found in 78% of the patients with severe pancreatitis and in 19% of those with mild pancreatitis. The Ranson criteria greater than or equal to three were found in 45% of the patients with severe acute pancreatitis and in 16% of those with the mild form of the disease. The positive predictive value was 92% for the presence of alterations on the chest X-rays, 64% for the alteration of at least one of the abnormal findings on the chest X-ray and a peripheral leukocyte count greater than 13,000/mm3, 56% for a peripheral leukocyte count greater than 13,000/mm3, and 54% for the presence of Ranson criteria greater than or equal to three. The negative predictive values were similar. CONCLUSIONS: The presence of pleural or pulmonary alterations on chest X-rays may be useful in the Emergency Room for the early identification of patients with severe acute pancreatitis.

Electrocardiographic abnormalities in acute pancreatitis.

It has been reported that electrocardiographic abnormalities may be associated with acute pancreatitis. However, the data are lacking or sketchy. The aim of this study was to assess the frequency and type of electrocardiographic abnormalities present in patients with acute pancreatitis. Fifty-six consecutive patients with acute pancreatitis and without previous history of heart disease were studied. Eleven patients had arterial hypertension. Forty-one patients had mild pancreatitis and 15 had the severe form of the disease. On admission, all patients underwent a standard 12-leads electrocardiogram and a serum electrolyte determination. Nineteen healthy subjects were also studied as controls. Twenty-seven patients (48.2%) (10 with severe pancreatitis and 17 with mild pancreatitis) had a normal electrocardiogram. In the remaining 29 patients (51.8%), one patient with severe pancreatitis had atrial extrasystoles and eight had bradycardia (less than 60 beats/minute) (two with severe pancreatitis and six with mild pancreatitis); 14 patients had changes of the T-wave and/or the ST-segment (two with severe pancreatitis and 12 with mild pancreatitis); seven patients showed disturbances of the intraventricular conduction (one with severe pancreatitis and six with mild pancreatitis): four had left anterior hemiblock, two had complete left bundle branch block and one had left anterior hemiblock and incomplete right bundle branch block; one patient with mild pancreatitis had atrioventricular block (first degree). No differences in heart rate, RR interval, PR interval and QT interval were found when patients with acute pancreatitis were compared with healthy subjects, nor when patients with severe pancreatitis were compared with those having the mild form of the disease. Seventeen of the 29 patients with electrocardiographic abnormalities (52.6%) also had serum electrolyte alterations. More than 50% of the patients with acute pancreatitis had electrocardiographic abnormalities and electrolyte alterations were also present in about one-half of these.

Behavior of serum interleukin 12 in human acute pancreatitis.

We evaluated the behavior of sera interleukin p70 (IL-12p70) and IL-12p40 in patients with acute pancreatitis. Twenty-three acute pancreatitis patients were studied (12 had severe pancreatitis and 11 had mild pancreatitis). Twenty healthy subjects were studied as controls. Serum concentrations of total IL-12, IL-12p70, IL-12p40, and IL-6 were determined in all subjects on admission to the hospital; in patients with acute pancreatitis, the serum levels of these molecules also were determined for the 5 days after admission. Acute pancreatitis patients had serum concentrations of total IL-12, IL-12p40, and IL-6 significantly higher (p < 0.05) than those of the healthy subjects from the first to the sixth day of the study; serum concentrations of IL-12p70 were significantly higher in acute pancreatitis patients (p < 0.02) than in the healthy subjects on the first of the disease and significantly lower (p < 0.05) on the second, third, and fourth days of illness. Reduction of IL-12p70 in acute pancreatitis patients was not due to a failure of the monocytes because the production of IL-6 was increased. Increased amounts of IL-12p40 in acute pancreatitis patients may be responsible for their increased susceptibility to infection.

Serum pancreatic enzyme concentrations in chronic viral liver diseases.

Serum amylase and lipase concentrations were determined in 78 patients with chronic liver diseases [26 chronic active hepatitis (CAH) and 52 liver cirrhosis] and in 15 healthy subjects. Pancreatic isoamylase concentrations and macroamylase complexes were assayed in hyperamylasemic sera. Serum amylase levels were abnormally elevated in 27 patients (35%; 22 liver cirrhosis, 5 CAH), whereas serum lipase levels were elevated in 16 patients (21%; 15 liver cirrhosis, 1 CAH). In 9 of the 27 hyperamylasemic patients, the hyperamylasemia was of pancreatic type. Macroamylasemic complexes were not detected in hyperamylasemic sera. Patients with liver cirrhosis had serum levels of amylase and lipase significantly higher than both the healthy subjects and the patients with CAH, while no significant differences were found in serum levels of these enzymes in patients with CAH as compared to the healthy subjects. A decreased liver metabolism of serum amylase and lipase in patients with chronic infective liver disease, especially in those having liver cirrhosis, may lead to an accumulation of these enzymes in the blood.

Rhabdomyolysis and acute pancreatitis.

AIMS: To establish the incidence of rhabdomyolysis in patients with acute pancreatitis and to determine the effectiveness of myoglobin in assessing the severity of the disease. METHODS: Sixty-one patients having acute pancreatitis (33 males, 28 females, mean age 66 years, range 16-97 years) were studied; diagnosis of acute pancreatitis was based on the typical abdominal pain associated with elevated concentrations of serum lipase and further confirmed by imaging techniques. Rhabdomyolysis was defined as a level of serum myoglobin which is two or more times greater than the upper normal test limit. All patients had normal renal function at the time of the study, none had clinical and/or electrocardiographic signs of acute myocardial infarction and none were drug addicts. Forty-five patients had mild acute pancreatitis and 16 had the severe form of the disease. Serum myoglobin was determined using a nephelometric technique. RESULTS: Patients with mild pancreatitis had serum concentrations of myoglobin (median and range; 35.7, 24-713 microg/L) similar to those with severe pancreatitis (26.8, 24-710 microg/L). Twelve of the 61 patients with acute pancreatitis (20%) had serum myoglobin concentrations above the upper normal limit: eight of the 45 patients with mild pancreatitis (17.7%) and four of the 16 patients with severe pancreatitis (25.0%). Four of the 61 patients with acute pancreatitis (7%) had serum myoglobin levels more than twice the upper normal limit: two with mild disease and two with the severe form of pancreatitis. CONCLUSIONS: Rhabdomyolysis may occur asymptomatically in patients with acute pancreatitis, especially in those with the severe form of the disease. Serum myoglobin determination is not useful in establishing the severity of acute pancreatitis.

Pancreatic involvement associated with tricyclic overdose.

To our knowledge, only two cases of pancreatic involvement after tricyclic overdose have so far been described in the literature. We report another case of pancreatic involvement after tricyclic antidepressant overdose. Patient. A 30-year-old female was admitted to our Emergency Room after having ingested 800 mg of amitriptyline in a suicide attempt. On the second day of hospitalization, high serum values of amylase 823 IU/l (normal values < 220 IU/l) and lipase 1054 IU/l (normal value < 270 IU/l) were found. The pancreas appeared normal upon ultrasonography. Serum pancreatic enzymes further increased on the third day of hospitalization, peaked on the fourth day and then progressively decreased. Repeated ultrasonography examination did not show any alteration in the pancreatic gland. The patient was discharged eight days after admission. Fifteen days after the overdose episode, the ultrasonographic examination still did not show any alteration of the pancreatic gland, and serum amylase and lipase were 403 IU/l and 239 IU/l, respectively. In our opinion, serum pancreatic enzymes should be determined in patients with tricyclic overdose in order to detect possible pancreatic involvement.

Serum interleukin 6 in the prognosis of acute biliary pancreatitis.

BACKGROUND: Data concerning the interleukin 6 pattern in acute biliary pancreatitis are lacking. AIM: To define the best cut-off point of this molecule in differentiating the severe form of acute biliary pancreatitis from the mild form and to evaluate its sensitivity, specificity and diagnostic accuracy in the prognosis of acute biliary pancreatitis in comparison with those of serum C-reactive protein. PATIENTS: Forty-four patients with acute biliary pancreatitis: 27 patients with mild pancreatitis and 17 with the severe form of the disease. METHODS: Serum interleukin-6 and C-reactive protein concentrations were assessed in all patients on admission and for the following 5 days. RESULTS: Serum interleukin-6 levels were significantly higher (p < 0.02) in patients with severe acute biliary pancreatitis than in those with the mild form of the disease. No significant difference in serum C-reactive protein levels was found in the first 2 days in patients with mild biliary pancreatitis when compared to those with the severe form of the disease. Using a cut-off point of 2.7 pg/ml for serum interleukin-6 and 11 mg/dl for serum C-reactive protein, the sensitivity of the two molecules in assessing the severity of acute pancreatitis on the first day of the study was 87.5% for interleukin-6 and 6.3% for C-reactive protein, the specificity, 83.3% for interleukin-6 and 91.7% for C-reactive protein, and the accuracy 85.0% for interleukin-6 and 57.5% for C-reactive protein. CONCLUSIONS: Serum determination of interleukin-6 in the first 24 hours of the disease is a better marker of the severity of acute biliary pancreatitis than C-reactive protein.
