Abstract
Background A growing number of studies emphasize executive coaching as an effective developmental tool that managers can use to increase their performance in organizational settings. However, the coaching research suggests a large variety of processes and outcomes, lacking clarity on the primary psychological dimensions most impacted. Method Reviewing 20 studies with a rigorous methodological design that used control trials and pre-post tests, we evaluated and compared the relative effects of coaching on different types and sub-types of outcomes by means of a classification of coaching outcomes based on previously used taxonomies. Results The results indicate that the impact of coaching on behavioral outcomes was higher compared to attitudes and person characteristics outcomes, suggesting that behavioral coaching outcomes, especially cognitive behavioral activities, are the most impacted by executive coaching. Moreover, we found significant positive effects for some specific outcomes, such as self-efficacy, psychological capital, and resilience, indicating that executive coaching is effective in producing change even on dimensions considered relatively stable over time. The results show no moderation effects of the number of sessions. The length of the coaching program was a significant moderator only for the attitudes outcomes. Discussion These findings provide evidence that executive coaching is a powerful instrument for organizations to support positive change and personal development.

Abstract
Background Stenotrophomonas maltophilia-induced pulmonary haemorrhage is considered a fatal infection among haematological patients. The outcome can be explained by the patients’ immunity status and late diagnosis and treatment. Case presentation We present the rare case of successful outcome in a 61-year-old female who developed alveolar haemorrhage and acute respiratory distress syndrome 8 days after a chemotherapy session for her acute lymphoblastic leukaemia, in the context of secondary bone marrow aplasia. Stenotrophomonas maltophilia was isolated in sputum culture. The patient benefitted from early empirical treatment with colistin followed by trimethoprim/sulfamethoxazole, according to the antibiogram. Despite a severe initial clinical presentation in need of mechanical ventilation, neuromuscular blocking agents infusion, and ventilation in prone position, the patient had a favourable outcome and was discharged from intensive care after 26 days. Conclusions Stenotrophomonas maltophilia severe pneumonia complicated with pulmonary haemorrhage is not always fatal in haematological patients. Empirical treatment of multidrug-resistant Stenotrophomonas maltophilia in an immunocompromised haematological patient presenting with hemoptysis should be taken into consideration.

Abstract
AIM To retrospectively analyze the epidemiological, clinical and pathological data of parotid tumors. MATERIAL AND METHODS Reassessment of the histologic diagnosis of parotid tumor in the patients admitted to the Oral and Maxillofacial Surgery Unit of the Iasi "Sf. Spiridon" University Emergency Hospital during 2009-2013. Data on gender, age, place of residence, location, size, surgical procedure type and histopatological type were recorded. RESULTS The risk of developing pleomorphic adenonma is 7.40 times higher in women and 4.08 times higher before the age of 50 years. The risk of Warthin tumor is 16.47 times higher in male patients and 3.58 times higher in urban patients. People older than 50 years have a 7.14 times higher risk of developing malignancy and rural people have a 2.41 times higher risk of developing cancer. Diabetes, obesity and systemic hypertension were not important risk factors in our study. CONCLUSIONS According to this study age and the place of residence could be important predictors for parotid gland tumors. Since in Romania there are few epidemiological data regarding the parotid gland pathology, further cohort studies are needed for a better understanding of their clinical and pathological behavior.

Abstract
The clear seasonality of varicella infections in temperate regions suggests the influence of meteorologic conditions. However, there are very few data on this association. The aim of this study was to determine the seasonal pattern of varicella infections on the Mediterranean island of Mallorca (Spain), and its association with meteorologic conditions and schooling. Data on the number of cases of varicella were obtained from the Network of Epidemiologic Surveillance, which is composed of primary care physicians who notify varicella cases on a compulsory basis. From 1995 to 2012, varicella cases were correlated to temperature, humidity, rainfall, water vapor pressure, atmospheric pressure, wind speed, and solar radiation using regression and time-series models. The influence of schooling was also analyzed. A total of 68,379 cases of varicella were notified during the study period. Cases occurred all year round, with a peak incidence in June. Varicella cases increased with the decrease in water vapor pressure and/or the increase of solar radiation, 3 and 4 weeks prior to reporting, respectively. An inverse association was also observed between varicella cases and school holidays. Using these variables, the best fitting autoregressive moving average with exogenous variables (ARMAX) model could predict 95 % of varicella cases. In conclusion, varicella in our region had a clear seasonality, which was mainly determined by solar radiation and water vapor pressure.

Abstract
The evidence that biologically active food components are key environmental factors affecting the incidence of many chronic diseases is overwhelming. However, the full extent of such components in our diet is unknown, as is our understanding of their mechanisms of action. Beyond the interaction of these food components with the gut and intestinal immune functions, whey proteins such as lactoferrin are being tested as anticancer agents. Lactoferrin is an iron-binding protein that has been reported to inhibit several types of cancer. In the present work, the effects of bovine milk lactoferrin on human breast cancer HS578T and T47D cells were studied. The cells were either untreated or treated with lactoferrin concentrations ranging from 0.125 to 125 μM. Lactoferrin decreased the cell viability of HS578T and T47D by 47 and 54%, respectively, and increased apoptosis about 2-fold for both cell lines. Proliferation rates decreased by 40.3 and 63.9% for HS578T and T47D, respectively. For the T47D line, cell migration decreased in the presence of the protein. Although the mechanisms of action are not fully known, the results gathered in this work suggest that lactoferrin interferes with some of the most important steps involved in cancer development.

Abstract
AIMS Poultry meat is considered a major source of Campylobacter. This micro-aerobic bacterium is commonly responsible for foodborne illness. This work focuses on the isolation of Campylobacter coli lytic bacteriophages (phages) against target C. coli strains. METHODS AND RESULTS A method involving the enrichment of free-range chicken samples in a broth containing the target C. coli strains and salts (CaCl(2) and MgSO(4)) was used for phage isolation. This method allowed the isolation of 43 phages that were active against 83% of the C. coli strains used in the isolation procedure. Approximately 65% of the phages were also effective against Campylobacter jejuni strains. CONCLUSIONS The use of target pathogens in the phage isolation step improves the likelihood of detecting and isolating phages for the control of these specific strains. SIGNIFICANCE AND IMPACT OF THE STUDY This technique will be valuable in the context of phage therapy for enriching for phages that are active against specifically identified strains of bacteria, for example from a food poisoning outbreak or epidemic strains resistant to multiple antibiotics. In these situations, using the conventional methods for searching for bacteriophages active for these particular strains can be a time-consuming, if not an unsuccessful process. Using the isolation method described in this manuscript, the particular strains can be added to the enrichment broth increasing the probability of finding phages against them. Therefore, it will shorten the time needed for seeking phages able to lyse target strains, which in most of the cases, because of the rapid increase in antimicrobial-resistant bacteria, is of crucial importance.

Abstract
INTRODUCTION Influenza disease is subjected to surveillance by national networks (RC) that predict the epidemic behaviour by reporting clinical and virological data. OBJECTIVES To evaluate the effectiveness of the paediatric respiratory samples in the Balearic Islands RC in the last five epidemic seasons. MATERIAL AND PATIENTS A breath sample was taken from paediatric patients in the RC who had flu symptoms. The samples were inoculated in the MDCK cell line. We reviewed the epidemiological data of patients with a culture positive to influenza A and B. RESULTS A total of 338 pharyngeal swabs from the RC were analysed during the study period. Of these, 65 (19.3%) belonged to <14 years old patients, and 44.6% of the samples were positive as opposed to 39.1% of adult respiratory samples. The influenza A virus was isolated in 24 paediatric samples (82.7%) and the influenza B virus in 5 (17.3%). The mean age of the paediatric patients of the RC who were positive was 8.5 years. Only 3 patients in the 0-4 year old group were positive (10.3%) and 26 patients (89.7%) in the 5-14 years old group. CONCLUSIONS In spite that paediatricians represented only 22% of the RC doctors and obtain the 19.3% of all respiratory samples, the percentage and effectiveness of these is higher that that obtained in the adult population.

Abstract
In a time when conventional antibiotics are becoming increasingly less effective for treatment of infections, the relationship between bacteria and antimicrobial resistance is becoming more and more complicated. This paper provides a current review of studies reported in the literature pertaining to the antibiotherapy of human urinary tract infections (UTI), in a way that helps the reader direct a bibliographic search and develop an integrated perspective of the subject. Highlights are given to (bio)pathogenesis of uncomplicated cystitis. Features associated with the antibiotherapy of UTI such as development of resistance are presented in the text systematically. This review discusses recent advances in the understanding of how the predominant uropathogen Escherichia coli interacts with its host and leads to infection; so one can understand some of the reasons behind antibiotherapy failures.

Abstract
Protozoa and metazoa are considered good indicators of the treatment quality in activated sludge systems due to the fact that these organisms are fairly sensitive to physical, chemical and operational processes. Therefore, it is possible to establish close relationships between the predominance of certain species or groups of species and several operational parameters of the plant, such as the biotic indices, namely the Sludge Biotic Index (SBI). This procedure requires the identification, classification and enumeration of the different species, which is usually achieved manually implying both time and expertise availability. Digital image analysis combined with multivariate statistical techniques has proved to be a useful tool to classify and quantify organisms in an automatic and not subjective way. This work presents a semi-automatic image analysis procedure for protozoa and metazoa recognition developed in Matlab language. The obtained morphological descriptors were analyzed using discriminant analysis, neural network and decision trees multivariable statistical techniques to identify and classify each protozoan or metazoan. The obtained procedure was quite adequate for distinguishing between the non-sessile protozoa classes and also for the metazoa classes, with high values for the overall species recognition with the exception of sessile protozoa. In terms of the wastewater conditions assessment the obtained results were found to be suitable for the prediction of these conditions. Finally, the discriminant analysis and neural networks results were found to be quite similar whereas the decision trees technique was less appropriate.

Abstract
OBJECTIVES Anorexia nervosa is an eating disorder that combines malnutrition, amenorrhea, and distorted body image. To learn more about the course of this disease we undertook a retrospective study of girls diagnosed with anorexia nervosa in the Saint Etienne Endocrinology Department between 1979 and 2004. METHODS Patients were diagnosed according to DSMIV criteria. Data collected to complete the Morgan-Russell outcome assessment schedule included chronology of illness, patients' morphological features, anorexia type, treatment choice, patient's gynecological history, and social status. RESULTS The study included 206 cases. The average follow-up period was 8.3 +/- 5.3 years. Defining recovery as stable BMI>17.5 kg/m2 for at least one year and recovery of normal menstruation, full recovery was observed in 55.8% and partial recovery in 25.7%, while 18.5% remained chronically ill. Early onset (i.e., during adolescence) was associated with good prognosis, and advanced emaciation and delayed or insufficient medical care with poor prognosis. CONCLUSIONS The seriousness of this disease is due more to the incidence of cases that become chronic than to the mortality rate. Prediction of severity would be improved by taking into account underlying personality traits, such as addictive tendencies and depression.

Abstract
Increasing environmental pollution and the continuous development of new chemicals and drugs has led to ever growing concern about the potential effects of these compounds directly or indirectly on human health. As concerns water pollution, protozoa seem to be an excellent tool to assess both toxicity and pollution: they are regarded as biological indicators of pollution when their presence or absence can be related to particular environmental conditions, and they are considered test organisms when a species or population is used to evaluate the toxicity of relevant toxic compounds. Thus, an integrated approach is being developed to assess how toxic compounds affect the different biological levels of organisation--from the community level to the species level--of ciliated protozoa. The present paper reports and discusses the current state of the art of this approach.

Abstract
This paper describes a critical evaluation of a miniaturised colorimetric assay, using MTT (3-[4,5-dimethyl-thiazol-2-yl]-2,5-diphenyl-tetrazolium bromide) reduction, applied to protozoan viability testing. The toxic substances used were copper, zinc, Triton X-100 (a membrane surfactant) and cycloheximide (an inhibitor of the protein synthesis). The viability assay of the ciliate protozoan Tetrahymena pyriformis was optimised in terms of MTT concentration and incubation time. Since protozoa are non adherent cells the MTT assay was modified in order to maintain the medium in the well. MTT proved to be effective in the measurement of Tetrahymena pyriformis viability. Four hours of MTT incubation followed by 30 minutes of incubation with DMSO were found to be the best incubation times for optical density reading. Furthermore, 10 mg/ml of MTT solution was the concentration that gave higher values of optical densities with minor medium interference.

Abstract
Protozoa, and particularly ciliates, are essential in aerobic purification processes of wastewaters and have proved to be very sensitive to environmental changes. The physiological response of the ciliate Tetrahymena pyriformis was assessed in terms of mortality, growth and grazing capacity after exposure to four toxicants: copper, zinc, cycloheximide and Triton X-100. In the ranges of concentrations used, mortality, inhibition of growth and inhibition of grazing were observed with all toxicants employed, but in different ways. Copper and zinc showed lower toxicity than observed in other studies with protozoa, though some of the present results are in accordance with those reported by other authors. This supports the importance of the organism tested and the experimental conditions of the bioassays.

Abstract
Monensin, a growth-promoting agent and coccidiostat used in veterinary medicine, was studied in terms of its effects on the development of female rats and their offspring when added to the diet. Young female rats received 100 or 300 ppm monensin mixed with powdered chow diet until adulthood, when they were mated and their offspring were evaluated for physical and neurobehavioural development. The data showed that 1) exposure to the higher monensin concentration reduced female body weight; no deaths occurred after exposure to the two monensin concentrations; 2) the offspring of the experimental group receiving 300 ppm monensin presented a weight reduction from 10 to 21 days of lactation; 3) incisor eruption was delayed only in females after exposure to the 100 ppm concentration. We conclude that exposure to monensin during development induces toxicity in female rats and has a notable adverse effect on growth with some limited effects on selective milestones of physical and functional development of the offspring during the postnatal period.

Abstract
Lispro is a human insulin analogue with a very rapid onset of action, and a shorter duration of activity than soluble insulin. In order to assess the therapeutical value of lispro, we have had an open-label, non-comparative study, for 12 weeks, involving 19 IDDM patients. The treatment regimen with lispro and Humulin N has been adapted depending on each patient characteristics. Patients attended three visits, and the main metabolic control parameters included values of hemoglobin Alc, fasting and postprandial blood glucose monitoring. The patients themselves monitored their blood glucose using a glucometer. The mean age value of 19 patients (8 females and 11 males) was 22.32 (+/- 13.59) years. In patients previously receiving insulin treatment, therapy with lispro insulin significantly reduced postprandial glucose values. Lispro has been administered t.i.d. in 14 patients, and b.i.d. in 5 patients. At visit 1, mean value of HbAlc was 10.32% (+/- 1.63%); at visit 3, mean HbAlc was 9.90% (+/- 1.59%). Total insulin daily dose and the rate of short and long acting insulin did not change from visit 1 to visit 3. There has been reported only one serious adverse event during the study: a ketoacidosis due to a technical dosing error. Ten patients have reported mild hypoglycemic episodes. The outcomes of clinical study and of Quality of Life Questionnaire suggests that lispro--the first human insulin analogue used in humans--is effective, safe, and it is broadening beneficially the spectrum of insulins.

Abstract
Insulin antibodies (% binding) were determined by RIA method in 404 insulin-treated diabetic patients divided into two groups: (A) primary insulin-dependent patients (Type I diabetes): 300 cases, 170 M, 130 F, mean age +/- SD 29.2 +/- 7.5 yrs, disease and insulin treatment duration 7.7 +/- 6 yrs: (B) Type II diabetic patients needing insulin (secondary insulin-dependence): 104 cases, 47 M, 57 F, aged 53.4 +/- 9.2 yrs, duration of diabetes 13.1 +/- 8.3 yrs, and of insulin treatment 3.1 +/- 2.1 yrs. Both groups of patients were with the same types of insulin preparations. In 297 cases, all belonging to group (A), fasting C-peptide was also determined. The titre of insulin antibodies was significantly (p less than 0.001) higher in patients with secondary insulin dependence than in those with primary insulin dependence (22.96 +/- 15.1% vs 10.25 +/- 9.89) in spite of the longer duration of insulin treatment in the later group; the mean C-peptide value found in 58 Type I diabetic patients with a binding capacity less than 10% was significantly lower (p less than 0.001) than that found in 11 Type I diabetic cases with a binding capacity greater than 20% (0.091 +/- 0.57 vs 0.273 +/- 0.37 pmol/ml); no correlation was found between insulin antibodies and metabolic control, insulin requirements or chronic complications.

Abstract
Studies were conducted using uni- and multilamellar liposomes to establish optimum conditions for influenza antigen incorporation in view of their transport to the target cells for experimental influenza prophylaxis in hybrid white mice. Radiometric determinations showed a good level of preparation purification, a good efficiency of incorporation in liposomes of the active biological material, the liposome linked radioactivity distribution among different organs. Charged liposomes induced solid and long lasting resistance against influenza control infection.

Abstract
Two cases of acute chondrolysis of the upper femoral epiphysis associated with protrusio acetabuli are reported in two girls respectively 13 and 12 Y.O. The disease was unilateral in one patient and bilateral in other. Acute chondrolysis is characterized by onset of pain, restricted movements of the hip and evolution to an hip ankylosis within a few months. As usual no evidence of inflammatory disease could be shown at biology or at pathology of synovial membrane or of femoral head. CT and MR studies proved to be contributive in the first case. It's the author's opinion that in these 2 cases, chondrolysis appears as a complication of preexistent Protrusio Acetabuli.

Abstract
19 specimen of pathologically proved multicystic kidneys were opacified; first through the ureter and second, if the ureter was not patent, through a puncture of one of the cysts (or several if the first cyst did not communicate with the ureter or with other cysts). The results are as follows. The ureter was hypoplastic but patent in 12 and communicated with some of the cysts in 9 or with all the cysts in 3. These communications consisted of large (12 cases) or small (15 cases) canals, or both large and small canals (11 cases). When patent, the ureter was connected to these canals. Moreover in most of the cases, there was a communication between cysts through such canals. Finally, only 3 cases fitted with the classical description having an atretic ureter and non communicating cysts. Our conclusion is that the same basal defect is present in congenital obstructions of pelvis and calyces; there is a continuous spectrum of malformations between congenital hydronephrosis, hydrocalyces and multicystic kidneys.

Abstract
The authors report 3 rare cases of pseudo-ureteroceles corresponding to a vesical imprint of an ectopic extra-vesical megaureter. When an ectopic extra-vesical ureter follows a sharp juxta-vesical buckle, it can give a deep imprint on the bladder and look similar to an ureterocele. I.V.P. and U.S. can be as misleading since the appearance of this type of megaureter and ureterocele can be similar, and differential diagnosis can be difficult. Such situations are rare. In a ten years of pediatric urologic practice, the authors who have investigated 51 ureteroceles and 26 extravesical ectopic ureters, have only observed 3 children with this lesion. These 3 cases corresponded to two simple ureters, in a 3 year old boy and in a 2.5 year old girl, and one upper ureter of a complete duplex system in a neonate baby girl with antenatal discovery. The clinical, radiological, sonographical and endoscopic clues to the diagnosis are discussed and illustrated.

Abstract
Cavernous haemangiomas, the most frequent benign tumours of the liver, are discussed by the authors in connection with 50 personal cases and surveillance of 35 solitary hyperechoic nodules less than 3 cm diam. without clinical or biological abnormalities. All the diagnostic images are reviewed but attention is focussed on ultrasound. All US patterns may be observed, but if the lesion is less than 3 cm, the echostructure is often hyperechoic and homogeneous. In view of their asymptomatic nature and the absence of risk of evolution for these small hyperechoic lesions, it appears legitimate to propose surveillance merely by US if there are no clinical symptoms and if liver function tests are normal.

Abstract
In connection with 11 observations of aberrant pancreas in the gastro-duodenal area, the authors review the general and radiological features of this pathology. In ten of the personal cases reported on, radiological examination allowed diagnosis following discovery of an intramural image centered around an umbilication. While not uncommon, pancreatic heterotopias are generally fortuitous findings due to the usual absence of clinical symptoms. They are small, and tend to occur in the digestive tract, especially in the antro-duodenal region. Possible complications include adenomatous transformation which may or may not be insulinogenic, cystic degeneration, cystenadenoma and carcinoma. Such complications are rare, however, and are generally not discovered before surgery. Radiological examinations were negative in 23,7% of the cases reviewed; while the typical image of a rounded filling defect centered around an umbilication is easy to diagnose, the value of radiology is considerably less when dealing with peduncular, subserous or complex forms. Although certain authors recommend only surveillance following radiological and endoscopic detection of a small aberrant pancreas, the majority of authors advise exeresis.

Abstract
In connection with 141 cases of parotid tumours, 21 adenopathies of the parotid region and 22 cases of parotitis, the authors define the role of ultrasonography in the exploration of the salivary glands. Use of simple criteria permits differentiation of benign from malignant tumours with a good degree of sensitivity (79.8% in our series). This score allows ultrasonography to be offered as the first complementary examination when dealing with a tumefaction of the parotid region. When ultrasonographic findings evoke a malignant lesion, a CT scan seems necessary to evaluate any extension in depth. In contrast, ultrasonography does not appear justified in cases of parotitis or lithiasic pathologies.

Abstract
Purified and unpurified cell-free systems prepared from the chorioallantoic membrane of embryonated eggs were tested for polypeptide synthesis in the presence and absence of influenza virus RNA. Both systems exhibited an endogenous messenger activity determining 3H-phenylalanine incorporation into polypeptides in the absence of virus RNA. However, addition of influenza virus RNA to the systems clearly stimulated amino acid incorporation into polypeptides, offering the possibility of studying some aspects of the viral protein biosynthesis mechanism.
