Abstract
We reconstructed a transcriptional regulatory network for adrenocortical carcinoma (ACC) using transcriptomic and clinical data from The Cancer Genome Atlas (TCGA)-ACC cohort. We investigated the association of transcriptional regulatory units (regulons) with overall survival, molecular phenotypes, and immune signatures. We annotated the ACC regulons with cancer hallmarks and assessed single sample regulon activities in the European Network for the Study of Adrenal Tumors (ENSAT) cohort. We found 369 regulons associated with overall survival and subdivided them into four clusters: RC1 and RC2, associated with good prognosis, and RC3 and RC4, associated with worse outcomes. The RC1 and RC3 regulons were highly correlated with the 'Steroid Phenotype,' while the RC2 and RC4 regulons were highly correlated with a molecular proliferation signature. We selected two regulons, NR5A1 (steroidogenic factor 1, SF-1) and CENPA (Centromeric Protein A), that were consistently associated with overall survival for further downstream analyses. The CENPA regulon was the primary regulator of MKI-67 (a marker of proliferation KI-67), while the NR5A1 regulon is a well-described transcription factor (TF) in ACC tumorigenesis. We also found that the ZBTB4 (Zinc finger and BTB domain-containing protein 4) regulon, which is negatively associated with CENPA in our transcriptional regulatory network, is also a druggable anti-tumorigenic TF. We anticipate that the ACC regulons may be used as a reference for further investigations concerning the complex molecular interactions in ACC tumors.

Abstract
Contaminant levels are lower in Antarctica than elsewhere in the world because of its low anthropogenic activities. However, the northern region of the Antarctic Peninsula, is close to South America and experiences the greatest anthropogenic pressure in Antarctica. Here, we investigated, in two Antarctic Peninsula islands, intra and interspecific factors that influence the concentrations of 17 trace elements (TEs) in blood and feathers of three penguin species breeding sympatrically in relation to their trophic ecology assessed via a stable isotopic approach (C, N and S). Geographical location, foraging zone (δ13C and δ34S) and diet influences the interspecific difference, and sex and maturity stage diet influence the intraspecific difference of Pygoscelis penguins. Penguins from Livingston showed higher values (mean, ng. g-1, dry weight - dw) of Zn (103), Mn (0.3), and Fe (95) than those from King George Island (Zn: 80, Mn: 1.9, and Fe: 11). Gender-related differences were observed, as males showed significantly higher values (mean, ng. g-1, dw) of Rb (3.4) and δ15N in blood of gentoo, and Ca (1344) in Adélie feathers. Chicks of gentoo and Adélie presented higher Zn, Mg, Ca, and Sr and lower 13C values in blood than adults. The highest concentrations (mean, ng. g-1, dw) of Cd (0.2) and Cu (26), and the lowest δ15N values were found in chinstrap. Geographical, intraspecific (i.e., ontogenetic and gender-related) and interspecific differences in feeding seemed to have influenced TE and stable isotope values in these animals. The TE bioaccumulation by penguins may have also been influenced by natural enrichment in environmental levels of these elements, which seems to be the case for Fe, Zn, and Mn. However, the high level of some of the TEs (Mn, Cd, and Cr) may reflect the increase of local and global human activities.

Abstract
BACKGROUND Pharmacological treatments have been successfully used to treat Generalized Anxiety Disorder (GAD). The mainstay for the pharmacological treatment of GAD in past decades has been the use of benzodiazepine and non benzodiazepine anxiolytics. Data emerging over the last two decades have shown that antidepressants may be equally effective to anxiolytics for treating GAD. The use of antidepressants for treating GAD may be advantageous, due to the fact that GAD presents a high co morbidity ratio with major depressive disorder (62%) and dysthymia (37%). OBJECTIVES To assess the efficacy and acceptability of antidepressants for treating generalized anxiety disorder. SEARCH STRATEGY Cochrane Collaboration Depression, Anxiety and Neurosis Controlled Trials Register - CCDANCTR (up to May 2002), Anxiety Neurosis (up to May 2002) and Cochrane Controlled Trials Register (CENTRAL/CCTR) (up to May 2002), MEDLINE (1966 to May 2002), LILACS (1982 to May 2002); reference searching; personal communication; conference abstracts and book chapters on the treatment of generalized anxiety disorder. SELECTION CRITERIA Randomised controlled trials were included. Exclusion criteria were: non randomised studies; studies which included patients with generalized anxiety disorder and another Axis I co-morbidity. DATA COLLECTION AND ANALYSIS The data from studies were extracted independently by two reviewers and relative risks, weighted mean difference and number needed to treat were estimated. People who died or dropped out were regarded as having had no improvement. MAIN RESULTS Antidepressants (imipramine, venlafaxine and paroxetine) were found to be superior to placebo in treating GAD. The calculated NNT for antidepressants in GAD is 5.15. Dropout rates did not differ between antidepressants. Only one study presented data on imipramine and trazodone. Imipramine was chosen as the reference drug and, therefore, data on trazodone could not be included in the meta analysis. Only one study was conducted among children and adolescents (Rynn 2001). The latter study showed very promising results of sertraline in children and adolescents with GAD, which warrants its replication in larger samples. REVIEWER'S CONCLUSIONS The available evidence suggests that antidepressants are superior to placebo in treating GAD. There is evidence from one trial suggesting that paroxetine and imipramine have a similar efficacy and tolerability. There is also evidence from placebo-controlled trials suggesting that these drugs are well tolerated by GAD patients. Further trials of antidepressants for GAD will help to demonstrate which antidepressants should be used for which patients.

Abstract
BACKGROUND Spontaneous pneumothorax with concomitant neoplastic diseases is unusual. Lung cancer and osteogenic sarcoma with pulmonary metastasis are the neoplasms that most frequently accompany the spontaneous pneumothorax. This article's purposes are to relate the occurrence of spontaneous pneumothorax associated with breast neoplasms and to discuss the main etiopathogenic factors involved in the process. MATERIAL AND METHODS The authors report a case of a 43-year-old black woman carrier of a left breast ductal carcinoma with bilateral pulmonary metastasis. Spontaneous pneumothorax appeared during multidrug chemotherapy, so it cannot be related to other causes. CONCLUSIONS Even though breast neoplasms cause lung metastases in about 60% of the cases, the coexistence of spontaneous pneumothorax and breast carcinoma is very rare. There was no report of this topic in the medical literature review during the last five years. The authors believe and discuss the multiple pneumothorax etiopathogenic factors related to this case.
