Treatment response for acute depression is not associated with number of previous episodes: lack of evidence for a clinical staging model for major depressive disorder. J Affect Disord 2013; 150:344-9. [PMID: 23683993 DOI: 10.1016/j.jad.2013.04.016] [Citation(s) in RCA: 14] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/21/2012] [Revised: 04/17/2013] [Accepted: 04/17/2013] [Indexed: 01/10/2023]
Abstract
Mental illness has been observed to follow a neuroprogressive course, commencing with prodrome, then onset, recurrence and finally chronic illness. In bipolar disorder and schizophrenia responsiveness to treatment mirrors these stages of illness progression, with greater response to treatment in the earlier stages of illness and greater treatment resistance in chronic late stage illness. Using data from 5627 participants in 15 controlled trials of duloxetine, comparator arm (paroxetine, venlafaxine, escitalopram) or placebo for the treatment of an acute depressive episode, the relationship between treatment response and number of previous depressive episodes was determined. Data was dichotomised for comparisons between participants who had >3 previous episodes (n=1697) or ≤3 previous episodes (n=3930), and additionally for no previous episodes (n=1381) or at least one previous episode (n=4246). Analyses were conducted by study arm for each clinical trial, and results were then pooled. There was no significant difference between treatment response and number of previous depressive episodes. This unexpected finding suggests that treatments to reduce symptoms of depression during acute illness do not lose efficacy for patients with a longer history of illness.

Abstract
OBJECTIVE Depression is a comorbidity affecting quality of life (QoL) in patients with Parkinson's disease (PD) and requires appropriate treatment. This study evaluated the tolerability, safety, and efficacy of duloxetine 60 mg once daily for 12 weeks in PD patients with major depressive disorder (MDD). RESEARCH AND DESIGN METHODS Non-comparative, open-label, multi-center study. MAIN OUTCOME MEASURES Tolerability was evaluated by discontinuation rate (acceptable if ≤ 19%) due to treatment-emergent adverse events (TEAEs) and motor symptoms (UPDRS). Safety measures were TEAEs, the UKU side effect rating scale, vital signs, weight, laboratory tests, and ECG. Efficacy measures included HAMD-17, BDI, CGI-S, PGI-I, and pain VAS. QoL was measured by PDQ-39. RESULTS Of the 151 patients enrolled, 8.6% (95% upper CI: 13.3%) discontinued the study due to TEAEs. Worsening in PD-related tremor and rigidity was not observed, activities of daily living significantly improved and UKU subscales progressively decreased. Clinically significant abnormalities in laboratory findings were limited to four cases of hypercholesterolemia and one increase of total bilirubin, CPK, and fasting glucose. Blood pressure, weight, and ECG did not change from baseline. HAMD-17 and PDQ-39 total score and individual domains, BDI, CGI-S, and PGI-I total scores significantly improved. CONCLUSIONS Duloxetine seems well tolerated and likely effective in the treatment of depression associated with PD, with no detrimental effects in PD signs and symptoms.

Abstract
Despite optimal treatment (complete cytoreduction and adjuvant chemotherapy), 5-year survival for advanced ovarian cancer is approximately 30% and most patients succumb to their disease. Cytoreductive surgery is accepted as a major treatment of primary ovarian cancer but its role in recurrent disease is controversial and remains a field of discussion mainly owing to missing data from prospective randomized trials. A critical review of literature evidence on secondary surgery in recurrent ovarian cancer will be described.

Abstract
Keratinocyte replicative senescence has an important role in time-dependent changes of the epidermis, a tissue with high turnover. Senescence encompasses growth arrest during which cells remain metabolically active but acquire a typical enlarged, vacuolar and flattened morphology. It is also accompanied by the expression of endogenous senescence-associated-β-galactosidase and specific gene expression profiles. MicroRNAs levels have been shown to be modulated during keratinocytes senescence, playing key roles in inhibiting proliferation and in the acquisition of senescent markers. Here, we identify miR-191 as an anti-proliferative and replicative senescence-associated miRNA in primary human keratinocytes. Its overexpression is sufficient per se to induce senescence, as evaluated by induction of several senescence-associated markers. We show that SATB1 and CDK6 3′UTRs are two miR-191 direct targets involved in this pathway. Cdk6 and Satb1 protein levels decrease during keratinocytes replicative senescence and their silencing by siRNA is able to induce a G1 block in cell cycle, accompanied by an increase in senescence-associated markers.

Abstract
It is now well established that the glutamatergic system contributes to the pathophysiology of depression. Exposure to stress, a major precipitating factor for depression, enhances glutamate release that can contribute to structural abnormalities observed in the brain of depressed subjects. On the other hand, it has been demonstrated that NMDA antagonists, like ketamine, exert an antidepressant effect at preclinical and clinical levels. On these bases, the purpose of our study was to investigate whether chronic mild stress is associated with specific alterations of the NMDA receptor complex, in adult rats, and to establish whether concomitant antidepressant treatment could normalize such deficits. We found that chronic stress increases the expression of the obligatory GluN1 subunit, as well as of the accessory subunits GluN2A and GluN2B at transcriptional and translational levels, particularly in the ventral hippocampus. Concomitant treatment with the antidepressant duloxetine was able to normalize the increase of glutamatergic receptor subunit expression, and correct the changes in receptor phosphorylation produced by stress exposure. Our data suggest that prolonged stress, a condition that has etiologic relevance for depression, may enhance glutamate activity through post-synaptic mechanisms, by regulating NMDA receptors, and that antidepressants may in part normalize such changes. Our results provide support to the notion that antidepressants may exert their activity in the long-term also via modulation of the glutamatergic synapse.

Abstract
We report a rare case of a 50 year old man with renal squamous cell carcinoma (SCC) who first came to our attention with renal colic and fever not responding to antibiotic or analgesic treatment. He had a long history of kidney stones, but had not undergone any imaging in the last 5 years. Physical examination revealed tenderness and a palpable mass in the right flank and lumbar region. A whole body CT scan was performed, revealing an 11 cm mass in the right kidney infiltrating the inferior vena cava. There were areas of calcification within the mass and multiple stones within the renal pelvis. The tumor was considered unsuitable for resection according to radiological and clinical criteria. The mass was biopsied percutaneously under CT guidance and histological examination revealed squamous cell carcinoma of the renal pelvis. The patient was treated with neoadjuvant chemotherapy and embolization of the renal artery. He died one month after diagnosis. To our knowledge this is the second reported case in the world of renal SCC infiltrating the inferior vena cava and with kidney stones.

Body-worn motion sensors detect balance and gait deficits in people with multiple sclerosis who have normal walking speed. Gait Posture 2012; 35:573-8.

Abstract
While balance and gait limitations are hallmarks of multiple sclerosis (MS), standard stopwatch-timed measures practical for use in the clinic are insensitive in minimally affected patients. This prevents early detection and intervention for mobility problems. The study sought to determine if body-worn sensors could detect differences in balance and gait between people with MS with normal walking speeds and healthy controls. Thirty-one MS and twenty-eight age- and sex-matched control subjects were tested using body-worn sensors both during quiet stance and gait (Timed Up and Go test, TUG). Results were compared to stopwatch-timed measures. Stopwatch durations of the TUG and Timed 25 Foot Walk tests were not significantly different between groups. However, during quiet stance with eyes closed, people with MS had significantly greater sway acceleration amplitude than controls (p=0.02). During gait, people with MS had greater trunk angular range of motion in roll (medio-lateral flexion, p=0.017) and yaw (axial rotation, p=0.026) planes. Turning duration through 180° was also longer in MS (p=0.031). Thus, body-worn motion sensors detected mobility differences between MS and healthy controls when traditional timed tests could not. This portable technology provides objective and quantitative mobility data previously not obtainable in the clinic, and may prove a useful outcome measure for early mobility changes in MS.

Abstract
Abstract
BACKGROUND: Among the different chemotherapeutic options available for adjuvant treatment of early breast cancer (EBC), anthracycline-containing regimens represent prevalent choices. OSCAR/ABC is an observational, prospectic, multicentric study aimed at evaluating, in the clinical practice, the relevance of cardiac dysfunction and congestive heart failure (CHF) associated to “free choice”, anthracycline-containing adjuvant regimens and to identify patients at increased cardiac risk. PATIENTS AND METHODS: patients candidate to receive adjuvant anthracycline-containing chemotherapy, will be enrolled in the study. Data on demographic and clinical characteristics of patients (age, cardio-vascular comorbidity) tumor features (TNM, histotype, ER and PgR status, Ki67, and HER2 status), type of adjuvant regimen and tolerability of treatment will be collected and centrally registered at the Consorzio Interuniversitario Nazionale per ***1a Bio-Oncologia (CINBO) using e-CRFs. Data on type, sites and doses of radiotherapy performed will be collected, to evaluate the possible impact on cardiac function. Primary aim of the study is to evaluate the prevalence of cardiac dysfunction and CHF among the whole population enrolled, particularly according to risk criteria and type of administered chemotherapy. Cardiac dysfunction is defined as limiting cardio-vascular toxicity (≥ Grade 3 dyspnea, arrhytmia, hypertension) and/or asymptomatic LVEF reduction ≥20% (if >50% at the baseline) or ≥10% (if ≤50% at baseline); CHF is defined as clinical diagnosis and/or symptomatic LVEF reduction ≥20% (if >50% at the baseline) or ≥10% (if ≤50% at baseline). Assessment of cardiac risk involves the evaluation of age (< vs ≥ 65 years), cardio-vascular comorbidities (requiring treatment or not) and Left-Ventricular Ejection Fraction LVEF (> vs ≤ 55%) at diagnosis. Clinical and instrumental cardiac evaluation (ECG, Ecocardiography) will be performed at study entry, on-treatment and up to 5 years thereafter. Secondary objective of the study is to evaluate the clinical properness of different adjuvant anthracyclines-containing chemotherapy options, with regard to prevalence of therapeutic regimens, safety, efficacy (DFS and OS) and costs analysis. Cardiac safety and general toxicity on-treatment will be evaluated according to NCI criteria. The expected enrollment is 1,200 patients in 36 months. From September 2010 to May 2011, 7 of the 13 Centers involved in the study are active, with 65 enrolled patients.

Abstract
BACKGROUND Obesity is associated with a systemic, low-grade inflammatory state. Although the relationship between obesity and semen parameters or prostate diseases has been previously investigated, the association between body mass index (BMI), prostate inflammatory diseases and color- Doppler ultrasound (CDU) of the male genital tract (MGT) has been poorly studied. AIM To evaluate the association between BMI and CDU features of the MGT, signs and symptoms of prostate inflammation, semen parameters. MATERIALS/SUBJECTS AND METHODS We studied 222 men seeking medical care for couple infertility. According to the World Health Organization classification, subjects were divided into 3 groups: normal weight (no.=131, BMI=18.5-24.9 kg/m2), overweight (no.=71, BMI=25.0-29.9 kg/m2), obese (no.=20, BMI≥30.0 kg/m2). All patients underwent simultaneous testosterone evaluation and seminal analysis, including interleukin 8 (sIL-8), along with scrotal and transrectal CDU, before and after ejaculation. Prostatitis symptoms were evaluated by National Institutes of Health- Chronic Prostatitis Symptom Index questionnaire. RESULTS After adjusting for age and testosterone levels, higher BMI was significantly related to higher prostate volume and several CDU features of the prostate, including macro-calcifications, inhomogeneity, higher arterial peak systolic velocity (the latter adjusted also for blood pressure), but not with abnormalities of testis, epididymis, seminal vesicles. Furthermore, higher BMI and BMI class were significantly related to higher sIL-8, a reliable surrogate marker of prostate inflammatory diseases, even after adjustment for age. Conversely, no associations among BMI, clinical symptoms of prostatitis or semen parameters were observed. CONCLUSIONS Subjects with higher BMI might develop CDU and biochemical signs suggestive of prostate inflammation, although not clinically overt.

Abstract
PURPOSE The aim of this study was to explore the diagnostic performance of multidetector computed tomography (MDCT) in characterising pancreatic metastases. MATERIALS AND METHODS CT examinations of 17 patients affected by pancreatic metastases were retrospectively reviewed. The primary malignancy was renal cell carcinoma (RCC) in eight cases, uterine leiomyosarcoma in two, lung carcinoma in four and breast carcinoma in three. CT images were assessed for lesion number, size and morphology. RESULTS Pancreatic lesions were solitary in seven cases and multiple in ten. Lesion size ranged between 8 and 40 mm. Metastases from RCC were hyperattenuating in the arterial phase, metastases from breast cancer and lung cancer were hypoattenuating and metastases from uterine leiomyosarcoma were inhomogeneous. Precise lesion characterisation was obtained by using CT examination in 12 cases. In the remaining five patients, all with solitary metastases from RCC, a precise diagnosis was not possible because the lesions could not be differentiated from a neuroendocrine tumour. CONCLUSIONS MDCT allowed pancreatic metastases characterisation in 70.5% of cases. The lesions were the manifestation of widely disseminated neoplastic disease, with the exception of metastases from RCC, which were exclusively located in the pancreas.

Abstract
BACKGROUND AND AIMS Metabolic syndrome (MS) has recently been claimed to be an important new risk factor for the occurrence of coronary heart disease (CHD) and cardiovascular disease (CVD) events, although it is simply a combination of known risk factors used in a dichotomized fashion. The aims of this analysis were to explore the predictive role of MS for CHD and CVD events in a population study, in comparison with using the same factors in a continuous fashion, with special emphasis on HDL cholesterol. METHODS AND RESULTS In the second examination of the Gubbio population study from central Italy, 2650 cardiovascular disease-free men and women, aged 35-74 years around 1990, were examined and followed-up for 12 years. The classic risk factors (sex, age, systolic blood pressure, serum cholesterol and smoking habits) were studied as predictors of CHD and CVD events, alone and with the contribution of other factors (HDL cholesterol, blood glucose, serum triglycerides and waist circumference) included in the so-called MS, based on several multivariate models. MS was also tested after adjustment for other risk factors. MS produced a predictive significant relative risk of 1.67 for CHD events and 1.82 for CVD events, but considering its single risk factors, the only ones contributing to prediction were HDL cholesterol and systolic blood pressure. Dedicated analyses showed that MS does not add anything to the power of prediction beyond the role of the single risk factors treated in a continuous fashion, while the best predictive power is obtained using classic risk factors (sex, age, smoking habits, total cholesterol, systolic blood pressure) with the addition of HDL cholesterol. CONCLUSIONS The predictive power of MS is bound only to the presence of HDL cholesterol and blood pressure and does not add anything to using the same risk factor treated in a continuous fashion.

Abstract
AIM The aim of this study was to evaluate whether the primary tumour maximum standardized uptake value (SUV(max)) plays an independent prognostic role in patients with non small cell lung cancer (NSCLC) and whether this role is limited by partial volume effect (PVE) and motion artefacts. METHODS One hundred and fifty-three consecutive patients underwent PET exam, surgery (R0 resection) and follow-up (mean 20.3; range 6-44.8 months). Correlation with Disease Free and Overall Survival (DFS, OS) was evaluated in the entire population for: SUV(max), clinical and histopathological features and pathological stage. To evaluate the PVE and motion artefacts' interferences on SUV calculation, the correlation between SUV(max) and DFS/OS was also calculated in the groups of patients with tumour diameter ≥ and < than 25 mm (group A and B, respectively). RESULTS In the entire population only TNM and SUV(max) resulted correlated with DFS/OS. However, SUV(max) was significantly correlated with DFS/OS in group A but not in group B. Furthermore, only in the group of patients with primary tumour diameter ≥ 25 mm (group A), tumour diameter, tumour histotype, and tumour necrosis resulted significantly related with SUV(max) at both uni and multivariate analysis. CONCLUSION TNM together with SUV(max) could be useful in giving a better prognostic stratification of patients with NSCLC; however technical limitations in the SUV calculation must be taken into account in patients with tumour diameter <25 mm.

Abstract
Progressive supranuclear palsy (PSP) is a neurodegenerative disease with no sufficient treatment options to date. The most devastating symptom is the loss of balance with consecutive falls. Based on the observation that postural control improved in patients with vestibular dysfunction after audio-biofeedback training, we tested the effects of this training in PSP patients. Eight PSP patients were included into an uncontrolled 6-week intervention trial. The focus of the training was the improvement of posture and dynamic balance by using audio-biofeedback. The device was well accepted. No adverse events occurred. A significant improvement in the Berg Balance Scale was observed (T2 vs. T1, p=0.016), which remained significant at the 4-week follow-up (T3 vs. T1, p=0.008). Significant improvement of the Parkinson's disease questionnaire was demonstrated. No significant changes were found in the Timed Up-and-Go Test, the Five Chair Rise Test, and in specific clinical scales. To our knowledge, the present study is the first to demonstrate that audio-biofeedback training with PSP patients is associated with improvements of balance and psychosocial aspects.

Abstract
Basal cell carcinoma is the most common cutaneous malignant tumor, accounting for up to 80% of non melanoma skin cancers. Surgery, radiotherapy and chemotherapy have been for long time the main options for its treatment. Electrochemotherapy (ECT) is a novel local treatment successfully used in primary skin tumors. We report a case of a man affected by ulcerated basal cell carcinoma treated with ECT. In our case ECT was successful in the management of extensive basal cell carcinoma in clinical conditions whereas other approaches, would have been dangerous and inappropriate. To our knowledge, ECT must be considered as an alternative of traditional techniques when they are contraindicated in relation to the appearance of the lesions or the patient medical history.

Abstract
Climate and meteorological conditions greatly affect agricultural activities, modifying plant responses and determining the quantity and the quality of production. In this respect, the aim of this research was to analyze the quality of winter durum wheat (Triticum turgidum L. var. durum), in terms of protein content through the use of meteorological information. Meteorological conditions were described utilizing both local weather station data (air temperature, cumulated precipitation) and large-scale information available freely on the internet, such as geopotential height (GPH), sea surface temperature (SST), and the North Atlantic Oscillation (NAO) index. The analysis was carried out for the period 1997-2009 in the Tuscany region, Central Italy. Grain protein was positively correlated with air temperature during the February to June period, and negatively with cumulative precipitation during the entire period from November to June. Protein content was also negatively correlated with 500 hPa GPH over Gibraltar and North-Western Africa during the March to June period and with the SST of the Atlantic Ocean south-west of the Canary Islands during the January to June period. Finally, with regard to the NAO, winter durum wheat quality was positively correlated with the specific index for several months, in particular during the winter period. These results demonstrate that precipitation and air temperature over the production area represent two crucial variables driving the vegeto-productive responses of winter durum wheat. On the other hand, the use of large-scale meteorological information showed great potential from the perspective of a local quality forecast system setup.

Abstract
Piedras Moras reservoir (32° 10'27" S and 64° 16' 29" W; 832 ha), integrates a series of artificial lakes belonging to the Rio Tercero basin (Córdoba, Argentina). During March 2009 an algal bloom occurred, coinciding with several animal species mortality, mainly wild birds. The goal of this work was to establish the trophic status of the reservoir in relation to that mortality. Variables were evaluated in situ (temperature and water transparency) and samples were taken in order to identify algal species, Chl-a concentration (spectrophotometry) and toxins - total microcystines- (inmuno-enzymatic assay, ELISA). Histopathology studies were made on Fulica sp. A strong heterogenity in water transparency was observed, and "patches" of Potamogeton berteroanus distributed all along the lake, with Secchi disk minimal and medium values of 0.15 and 0.94 m. Chl-a concentration oscillated from 35.7 to 320.9 mg.m-3. Predominant phytoplankton species were Anabaena spiroides and Microcystis aeruginosa (Cyanophyceae). Water temperature was 27.8 °C (±0.88). Maximal value of total microcystine concentration was 0.23 μg.L-1. Chl-a concentration at the moment when mass mortality occurred (2.022 mg.m-3), and histopathological observations, strongly suggest that the animals' death was due to cianotoxins.

Abstract
A weekly administration of alternating irinotecan or oxaliplatin associated to 5-Fluorouracil in advanced colorectal cancer was planned in order to evaluate a new schedule maintaining dose intensities of each drug as in double combinations and tolerability of the triplet association. The following weekly schedule was administered: irinotecan, days 1 and 15; oxaliplatin, days 8 and 22; 5-fluorouracil (5-FU) over 12-h (from 10:00 p.m. to 10:00 a.m.) timed flat infusion, days 1-2, 8-9, 15-16 and 22-23, every 4 weeks. Dose- finding and phase II study were planned. Thirteen patients were enrolled in the dose-finding study and 23 in the phase II study. The recommended doses of our study are: irinotecan 160 mg/m(2); oxaliplatin 80 mg/m(2); 5-FU 900 mg/m(2). The dose-limiting toxicity was diarrhea (35% of patients) but no cases of febrile neutropenia were observed. In 30 patients assessable for response two complete (6.7%) and 18 partial (60%) responses were observed, for an overall response rate of 66.7% (alpha 0.05, CI+/-17). The triplet association using this weekly alternating schedule is an active and well-tolerated outpatient regimen. Surgical removal of residual disease was considered in 5 patients and a radical resection was performed in 5 patients (147 %).

Abstract
IMPORTANCE OF THE FIELD Except for generalized anxiety disorder, few reports have been published on the efficacy, safety and tolerability of duloxetine in patients with anxiety disorders individually or in comorbidity with major depressive disorder (MDD). AREAS COVERED IN THIS REVIEW The literature search in Medline (dating back to 1966) and Embase (dating back to 1988) databases was conducted using the OVID interface on 9 April 2009, restricted to any article or abstract in English, per title, reporting any information on the use of duloxetine in patients with any anxiety disorder with or without concomitant MDD. A systematic review approach was taken. WHAT THE READER WILL GAIN The reader will gain knowledge of the current data available on the use of duloxetine to treat patients with anxiety disorders individually or in comorbidity with MDD. TAKE HOME MESSAGE Duloxetine could be considered an effective treatment option in the treatment of anxiety disorders individually or in comorbidity with each other, or with MDD; however, apart from the well-demonstrated efficacy, tolerability and safety of duloxetine in the treatment of MDD with or without anxiety and GAD, data on this subject are preliminary and very limited, and more research is warranted.

Abstract
Control of balance is complex and involves maintaining postures, facilitating movement, and recovering equilibrium. Balance control consists of controlling the body center of mass over its limits of stability. Clinical balance assessment can help to assess fall risk and/or determine the underlying reasons for balance disorders. Most functional balance assessment scales assess fall risk and the need for balance rehabilitation but do not differentiate types of balance deficits. A system approach to clinical balance assessment can differentiate different kinds of balance disorders and a physiological approach can determine underlying sensorimotor mechanisms contributing to balance disorders. Objective measures of balance using computerized systems and wearable inertial sensors can bring more sensitive, specific and responsive balance testing to clinical practice.

Abstract
PURPOSE The typical appearance of focal nodular hyperplasia (FNH) in radiological contrast techniques (helical CT or MRI) includes homogeneous enhancement in the arterial phase, but the exact timing for the best visualization of this pattern is unknown. The aim of the present study was to assess the ultrasound pattern of FNH with special attention to real-time contrast-enhanced ultrasonography (CEUS) appearance and specifically to the timing of perfusion patterns. MATERIALS AND METHODS 72 patients (60 females, 12 males) with a total of 90 FNH nodules with a diameter ranging from 8 to 100 mm (mean +/- SD, 40.6 +/- 21.5 mm) were examined continuously for at least 4 minutes using CnTI and CPS methods (ESAOTE, Genoa, Italy and Acuson-Siemens) after bolus injection of SonoVue (BRACCO, Milan, Italy). RESULTS 87 of 90 nodules showed the typical coin-like hyperechogenicity in the arterial phase. The remaining three nodules were all in the same patient and were diagnosed as FNH after resection. Contrast started to appear within the lesions after a mean of 15.7 +/- 4.6 seconds (range 7 - 27 s) and reached peak signal intensity, with the greatest differentiation between the lesion and the surrounding parenchyma, at around 22.6 +/- 7.0 seconds (range 14 - 72 s). In the late phase, 65 lesions (72.2 %) became isoechoic (after a mean of 80.8 +/- 85.7 s, range 20 - 300 s), 22 (24.4 %) slightly hyperechoic and 3 (3.3 %) faintly hypoechoic. CONCLUSION FNH shows a typical homogeneous hyperechoic pattern during the arterial phase in real-time CEUS which disappears slowly on average but occasionally even as soon as 20 seconds after contrast injection. If the first scans are taken later than 20 seconds after injection (which is still considered to be a full arterial phase), the ultrasound hyperechogenicity may be missed in some cases. Real-time study of these lesions is therefore strongly recommended to avoid possible false-negative results.

Abstract
OBJECTIVES Both duloxetine and venlafaxine are efficacious in treating patients with Major Depressive Disorder (MDD), even though the advantages in treatment patients with bipolar disorder is unclear. This study aimed to evaluate the efficacy of duloxetine vs venlafaxine in the acute treatment of unipolar and bipolar depression. MATERIALS AND METHODS The study was a non randomized controlled trial. The participants were 62 consecutive outpatients (41 men; 21 women) affected by unipolar and bipolar depression treated either with duloxetine and venlafaxine. RESULTS More patients treated with duloxetine had a positive response to treatment and remission both for depression (HAMD17 response: 90.3% vs 0.0%; p < .001; HAM-D17 remission: 48.4% vs 0.0%; p < .001), and anxiety (HAM-A response: 90.3% vs 6.5%; p < .001; HAM-A remission: 71.0% vs 6.5%; p < .001) than controls. Patients treated with duloxetine were also more likely to show a decrease in HAM-D17 suicidality (100% vs 45.2%; p less than .001) and an increase in the quality of life (SF-36 percentage of improvement: 6.35 [SD=9.66 vs -2.58 [9.98]; p less than .001) than controls. CONCLUSIONS Duloxetine is more effective in reducing anxiety and suicidal ideation. Both treatments were safe and tolerated, and both may be successfully used in unipolar and bipolar depression.

Abstract
Numerous stem cell niches are present in the different tissues and organs of the adult human body. Among these tissues, dental pulp, entrapped within the ‘sealed niche’ of the pulp chamber, is an extremely rich site for collecting stem cells. In this study, we demonstrate that the isolation of human dental pulp stem cells by the explants culture method (hD-DPSCs) allows the recovery of a population of dental mesenchymal stem cells that exhibit an elevated proliferation potential. Moreover, we highlight that hD-DPSCs are not only capable of differentiating into osteoblasts and chondrocytes but are also able to switch their genetic programme when co-cultured with murine myoblasts. High levels of MyoD expression were detected, indicating that muscle-specific genes in dental pulp cells can be turned on through myogenic fusion, confirming thus their multipotency. A perivascular niche may be the potential source of hD-DPSCs, as suggested by the consistent Ca2+ release from these cells in response to endothelin-1 (ET-1) treatment, which is also able to significantly increase cell proliferation. Moreover, response to ET-1 has been found to be superior in hD-DPSCs than in DPSCs, probably due to the isolation method that promotes release of stem/progenitor cells from perivascular structures. The ability to isolate, expand and direct the differentiation of hD-DPSCs into several lineages, mainly towards myogenesis, offers an opportunity for the study of events associated with cell commitment and differentiation. Therefore, hD-DPSCs display enhanced differentiation abilities when compared to DPSCs, and this might be of relevance for their use in therapy.

Abstract
Bromhidrosis is a clinical disorder characterized by excessive or abnormal foul axillary odour due to the interaction of apocrine glands with micro-organisms which causes a serious personal and social handicap for affected people. We present the case of a 50-year-old caucasian female with bromhidrosis. The patient referred that this symptom had begun two months previously. Her past treatments included antibacterial soap, topical antibacterial agents and perfumes, but none of these relieved the patient of the odour. A cultural examination of axillary smear was carried out and it revealed the presence of ciprofloxacin sensible Sphingomonas paucimobilis. Therefore the patient was treated with ciprofloxacin and after 1 week the infection resolved completely.

Abstract
BACKGROUND AND AIMS High intrarenal resistance index (RI) predicts renal function in several conditions; its use in the prediction of diabetic nephropathy (DN) is little explored. We aimed (1) to compare RI in diabetic and non diabetic hypertensive patients, and (2) to evaluate whether high RI is associated with clinical signs of DN and its progression over time. DESIGN observational, prospective. PARTICIPANTS 92 type 2 diabetic patients and 37 non-diabetic controls aged 40-70, with hypertension and normal renal function. We measured ultrasound RI and, among others, creatinine, estimated glomerular filtration rate and urinary albumin excretion rate (AER) at baseline and after 4.5 years follow-up. Progression of albuminuric state (i.e., transition from baseline normo-microalbuminuria to follow-up micro-macroalbuminuria) was evaluated. RI was significantly higher in diabetic than non-diabetic participants (0.69+/-0.05 vs 0.59+/-0.05, p<0.001). Diabetic patients with RI>or=0.73, i.e., above the 80th percentile of the RI distribution, had significantly higher baseline AER and a more frequent progression of the albuminuric state compared to patients with RI<0.73 (27.7microg/mg [12.1-235.4] vs 15.1microg/mg [8.6-33.4]; 52.9% vs 9.5%, respectively). AER increased significantly from baseline to follow-up in patients with RI>or=0.73 (from 27.7microg/mg [12.1-235.4] to 265.0microg/mg [23.8-1018.1], p<0.01), but not in those with RI<0.73 (from 15.1microg/mg [8.6-33.4] to 16.1microg/mg [10.7-67.2], ns). OR for progression of albuminuric state, adjusted for established predictors of DN, including baseline AER, was 5.01 (1.4-17.7, 95% CI) for patients with RI>or=0.73 vs <0.73. Findings were confirmed in patients with normoalbuminuria at baseline. CONCLUSIONS In diabetic patients, high RI (>or=0.73) is associated with features of DN and its progression over time, independent of albuminuria.

Abstract
4125 Background: Triplet combinations associating antimetabolites with irinotecan (CPT-11) and/or oxaliplatin (OHP) and/or bevacizumab (BEV) show increased activity in same phase III studies vs doublets, with objective responses (OR) between 40% and 60%. Thus we evaluated in a phase II study the addition of BEV to the triplet combination CPT-11/OHP/5-fluorouracil (5-FU) as first line chemotherapy in metastatic colorectal carcinoma (MCC). Methods: Main inclusion criteria: histologically diagnosis of colorectal cancer (CRC) with measurable disease; age 18–75 yrs; adequate bone marrow reserve and renal and hepatic function; no cardiac diseases; no uncontrolled hypertension; no thromboembolic diseases or coagulopathy, no preexisting bleeding diatheses. Treatment schedule: weekly 5-FU 12-h timed-flat-infusion (from 10:00 pm to 10:00 am) 900 mg/m2/d 1–2, 8–9, 15–16 and 22- 23; CPT-11 160 mg/m2 plus BEV 5 mg/kg days 1 and 15; OHP 80 mg/m2 days 8 and 22, every 4 weeks. A Simon two-stage optimal design was planned: power 80%, error probability α 5%, error probability β 20%, P0 50%, P1 70%, sample size 43 pts (I stage 8/15 OR; II stage 26/43 OR). Primary endpoint: OR. Secondary endpoints: time to progression (TTP), overall survival (OS), toxicity and quality of life. Results: Forty-eight pts were enrolled. Median number of cycles per patient was 5 (range 1–9). In the expected 43 pts assessable intent-to-treat (ITT), OR were 84% (α0.05, CI +12): 2 complete and 34 partial responses. In the overall 48 pts, 46 were assessable ITT: OR 80% (α0.05, CI +12), 2 complete and 35 partial responses, 4 stable disease and 5 progression. Median TTP was 12 months (2+-33+), median OS was 25 months (2+-34+), with a median follow-up of 12 months (2–34). Cumulative G3–4 toxicities by pts were: diarrhea 27%, mucositis 6%, hypertension 2%, hypertransaminasemy 2%, neutropenia 10%. No toxic deaths have occurred. Received-DI: CPT-11 84% of projected-DI, OHP 82%, 5-FU 85%, BEV 84%, per pt respectively. 17 pts (35%) had only liver metastasis and R0 resection was performed in 3 pts (18%). Conclusions: “Poker” combination with FIR-B/FOX schedule shows higher activity than triplet combinations. Thus it may be considered as the most active first line treatment of MCC. No significant financial relationships to disclose.

Abstract
Compelling evidence suggests that mood disorders are characterized by reduced neuronal plasticity that might be normalized by pharmacological intervention. Our study aimed to establish whether chronic antidepressant treatment could alter the modulation of the neurotrophin brain-derived neurotrophic factor (BDNF) under a stressful condition. Therefore, adult male Sprague-Dawley rats were treated for 21 days with vehicle or with the SNRI duloxetine and, 24 h after the last injection, exposed to an acute swim stress (5 min) before being killed 15 min later. We found that chronic duloxetine treatment was able to modulate the rapid transcriptional changes of BDNF isoforms produced by an acute swim stress. Indeed whereas the mRNA levels of BDNF exon IV were upregulated by stress in vehicle as well as in duloxetine-treated rats, a significant increase of exon VI and exon IX was only found in rats that were pretreated with the antidepressant. These differential effects are in part because of selective changes in signaling pathways involved in the control of BDNF transcription. Moreover, the acute stressful episode significantly increased the levels of mature BDNF protein in the synaptosomal compartment in rats that were pretreated with the antidepressant, but not in control animals. Our results suggest that chronic antidepressant treatment might affect the responsiveness of BDNF under stressful conditions, suggesting that pharmacological intervention could 'prime' neuroprotective pathways and render them more responsive to preserve cell function and viability.

Abstract
We treated 114 Ph'+ chronic myeloid leukemia (CML) patients, 105 of whom were in chronic phase (CP) and 9 in accelerated phase (AP), with interferon alpha-2b (IFN alpha-2b) at intermittent or daily doses of 2-5 MU/m2. Of 35 previously untreated CP patients, 22 (63%) showed complete hematological response (CHR). This was significantly influenced by initial risk status. In 19 of the 22 CHR patients the median of Ph'+ cells decreased from 100% to 58%. Of 36 patients pretreated for less than 12 months, 19 (53%) achieved CHR. CHR rate was significantly related to IFN dose. Cytogenetic improvement was observed in 15 of the 19 patients, the median of Ph'+ cells dropping from 100% to 76%, with complete suppression of the Ph' chromosome in 1 case. Of the 34 patients pretreated for greater than 12 months, 21 (62%) obtained CHR. Cytogenetic improvement was observed in 10 cases, the median of Ph'+ cells declining from 100% to 66%. 1 of 9 AP patients obtained CHR. After a median follow-up of 32 months for the 63 CHR patients, 49 (78%) are still in disease control: 34 on IFN therapy, 15 after bone marrow transplantation (BMT) (13 autologous and 2 allogeneic). Blastic transformation (BT) occurred in 9 of 63 (14%) CHR patients and in 24 of 51 (47%) patients with less than CHR. IFN alpha-2b has proved to be an effective treatment for CML. Its combination with other treatment modalities represents an interesting and promising approach for future studies.

Abstract
Serum apolipoprotein and lipoprotein concentrations, fatty acid spectra of various lipids, dietary habits and common risk factors for ischaemic heart disease were studied in 73 and 77 randomly selected, 50-year-old healthy men in Naples and Stockholm, respectively. Mean serum cholesterol concentration was higher in Stockholm than in Naples men (6.23 vs. 5.47 mmol/l, p less than 0.001) as were low (LDL) (4.08 vs. 3.57 mmol/l, p less than 0.001) and high (HDL) (1.40 vs. 1.25 mmol/l, p less than 0.001) density lipoprotein fractions. Mean serum triglyceride concentrations did not differ. Mean apolipoprotein B and C-I concentrations were higher in Stockholm men (1,116 vs. 1,020 mg/l, p less than 0.05 and 96 vs. 79 mg/l, p less than 0.01, respectively). Stockholm men derived significantly more of their calories from fat (38 vs. 28%, p less than 0.001) and the dietary fat had significantly lower polyunsaturated-to-saturated fatty acid ratio (P/S-ratio 0.29 vs. 0.51, p less than 0.001), and less from carbohydrate (44 vs. 49%, p less than 0.001) than Naples men, respectively. Mean caloric intake and mean weight/height index did not differ. Stockholm men had higher blood pressures, but there were more smokers among Naples men. The higher fat intake in Stockholm men may offer an explanation of the differences seen in lipoprotein and apoprotein concentrations and compositions but other factors, such as genetic influences cannot be excluded. A greater cholesterol flux through the plasma compartment in Stockholm men may be one important factor contributing to the higher incidence of ischaemic heart disease in this population.

Abstract
BACKGROUND AND PURPOSE Anticipatory postural adjustments (APAs), prior to step initiation, are bradykinetic in advanced Parkinson's disease (PD) and may be one of the factors associated with 'start hesitation'. However, little is known about APAs in the early stage of PD. In this study, we determined whether body-worn accelerometers could be used to characterize step initiation deficits in subjects with early-to-moderate, untreated PD. METHODS Eleven PD and 12 healthy control subjects were asked to take two steps. Postural adjustments were compared from center of pressure (COP) and from acceleration of the trunk at the center of mass level (L5). RESULTS Our findings show that APAs measured from the peak COP displacement toward the swing leg and the peak trunk acceleration toward the stance leg were smaller in untreated PD compared with control subjects. The magnitude of APAs measured from peak COP displacements and accelerations were correlated. CONCLUSION These results suggest that quantitative analysis of step initiation from one accelerometer on the trunk could provide useful information for the characterization of patients in early stages of PD, when clinical evidence of start hesitation may not be detectable. Ambulatory monitoring of step initiation is also promising for monitoring patient progression in the home environment, and eventually providing feedback for preventing freezing of gait episodes.

Composition and diversity of ichthyofauna in La Viña reservoir (Córdoba, Argentina). BRAZ J BIOL 2009; 69:49-55. [PMID: 19347145 DOI: 10.1590/s1519-69842009000100006] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.1] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/15/2007] [Accepted: 07/11/2007] [Indexed: 11/22/2022] Open
Abstract
Several dams have been built in central and north Argentina. There are more than 20 reservoirs in Córdoba province, with a total estimated surface area of around 15,000 ha. Although construction of dams continues, some aspects about the richness, abundance and diversity of ichthyofauna in many of these environments are unknown, which prevents adequate management of fish resources. The goal of this work was to evaluate specific richness and diversity of ichthyofauna in La Viña reservoir (31 degrees 47' S and 65 degrees 01' W, 1,050 ha, 846 m asl), one of the major reservoirs in Córdoba. Fifteen seasonal samplings were made in 1999-2002 using trawl nets and gillnets. A total of 3,242 specimens belonging to 7 species distributed in 5 orders and 5 families were caught. The tetra Astyanax eigenmanniorum (52.9%) and the silverside Odontesthes bonariensis (29.3%) were the most abundant species; the latter is the main target species for lake fishing and had greatest biomass (63.8%). Average diversity for all samples was H'T = 1.63 (95% confidence interval 1.49 to 1.77). Shannon-Wiener and Simpson diversity indexes values were generally intermediate. Specific richness of La Viña reservoir was moderate compared with other impoundments in central and north Argentina.

Abstract
BACKGROUND Randomized controlled trials (RCTs) of duloxetine (DLX), an inhibitor of both norepinephrine and serotonin transporters (SNRI), have tested its efficacy in acute major depressive disorder (MDD) versus placebo (PBO) or standard serotonin-reuptake inhibitors (SRIs) and require review, comparing analytical methods. METHOD Computerized searching to identify reports of RCTs of DLX in adult, acute MDD patients permitted meta-analytic pooling to estimate overall response and remission rates, to compare mixed-model, repeated measures (MMRM) versus last-observations-carried-forward (LOCF) analytical methods, and to assess relations of DLX dose to efficacy and adverse outcomes. RESULTS We identified 17 RCTs involving 22 comparisons (DLX versus PBO [n = 17) and DLX versus an SRI [n = 16]), based on MMRM and LOCF methods that allowed estimates of response (>or=50% improvement of depression scores) or remission (final depression score <or=7). There was a large overall DLX/PBO contrast (LOCF, RR = 1.42 [CI: 1.31-1.53], p < 0.0001, with a success rate of 65% [11/17]), and somewhat larger effects with MMRM in both response (MMRM: RR = 1.48 [95%CI: 1.31-1.66] versus LOCF: RR = 1.41 [CI: 1.28-1.56]; NNT 4.8 versus 6.5) and remission (MMRM: RR = 1.61 [CI: 1.41-1.85] versus LOCF: RR = 1.44 [CI: 1.27-1.63]; NNT = 5.9 versus 8.9). Based on LOCF methods, dropout rates were similar with DLX and PBO (RR = 1.04 [CI: 0.94-1.15]); DLX response was dose-dependent (r = +0.72, p = 0.001), and RCT-dropout rates were inversely related to DLX dose, but possibly artifactually. LIMITATIONS RCTs involving DLX are limited, with few direct comparisons to standard antidepressants. CONCLUSIONS DLX has good evidence of efficacy in acute, adult MDD, especially at doses of 80-120 mg/day, but remains inadequately tested against standard alternatives. MMRM analyses yielded slightly superior FLX/PBO contrasts than older LOCF methods.

Comparative diagnostic evaluation with MR cholangiopancreatography, ultrasonography and CT in patients with pancreatobiliary disease. Radiol Med 2009; 114:390-402. [PMID: 19266258 DOI: 10.1007/s11547-009-0374-x] [Citation(s) in RCA: 27] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/07/2008] [Accepted: 06/27/2008] [Indexed: 12/20/2022]
Abstract
PURPOSE The aim of this study was to directly compare the results of magnetic resonance cholangiopancreatography (MRCP) with those of ultrasonography (US) and multislice computed tomography (MSCT) in the diagnosis of pancreaticobiliary diseases. MATERIALS AND METHODS A total of 70 patients (41 men, 29 women) aged 22-89 years were studied either before (n=59) or after cholecystectomy (n=11) for biliary lithiasis. Clinical signs and symptoms were jaundice (n=15), abdominal pain (n=37) and proven biliary lithiasis (n=18). MRCP was performed in all patients, whereas abdominal US was performed in 55 (group 1) and MSCT in 37 (group 2) patients. A regional evaluation of the main structures of the pancreaticobiliary system was performed: gallbladder and cystic duct, intra- and extrahepatic bile ducts and main pancreatic duct. Histology (n=27), biopsy (n=5), endoscopic retrograde cholangiopancreatography (ERCP) (n=28) and/or clinical-imaging follow-up (n=10) were considered standards of reference. In particular, patients were classified as showing benign (n=47) or malignant (n=12) lesions or normal biliary anatomy (n=11). RESULTS In group 1, the results of MRCP and US were concordant in the majority (92%) of cases; however, statistically significant discordance (p<0.01) was found in the evaluation of the extrahepatic ducts, with nine cases (16%) of middle-distal common bile duct stones being detected on MRCP only. In group 2, the results of MRCP and MSCT were also concordant in most cases (87%). However, findings were significantly discordant when the intra- and extrahepatic ducts were analysed, with seven (19%) and six (16%) cases, respectively, of lithiasis being detected on MRCP only (p<0.01 for both). CONCLUSIONS The results of our study confirm the diagnostic potential of MRCP in the study of the pancreaticobiliary duct system. In particular, the comparison between MRCP and US and MSCT indicates the superiority of MRCP in evaluating bile ducts and detecting stones in the common bile duct.
