The resurgence of syphilis among pregnant women in southern Chile.

Background: National rates of HIV, gonorrhoeae and syphilis have increased in Chile in recent years, but it is not known if syphilis among pregnant women (PW) is also escalating.

Aim: To explore syphilis rates among PW in a southern Chilean region and to describe clinical features of mothers and offspring.

Patients And Methods: We selected PW with positive VDRL or T.

Exposure to Citalopram Mitigates Maternal Stress Effects on Fetal Brain Development.

Human epidemiological and animal-model studies suggest that separate exposure to stress or serotonin-selective reuptake inhibitor (SSRI) antidepressants during pregnancy increases risks for neurodevelopmental disorders in offspring. Yet, little is known about the combined effects of maternal stress and SSRIs with regard to brain development . We found that the placenta is highly permeable to the commonly prescribed SSRI (±)-citalopram (CIT) in humans and mice, allowing rapid exposure of the fetal brain to this drug.

[Aseptic meningitis associated to mumps during an epidemic outbreak].

We report two cases of acute aseptic meningitis associated to mumps in middle-aged women, one pregnant. Both presented shortly after parotid gland enlargement. Neurological complications were suspected by headache, fever and meningeal signs and confirmed by CSF findings (mononuclear predominant pleocytosis) with negative results for alternative causes.

Retrospective analysis of patients with advanced or metastatic gastric cancer in Colombia.

To assess patient and disease characteristics, treatment patterns, and associated costs in patients with advanced or metastatic gastric cancer (A/MGC) in Colombia, in both the public and private hospitals. A total of 145 patients who had received first-line chemotherapy treatment (platinum analog and/or a fluoropyrimidine) and were followed for at least 3 months after the last administration of a first-line cytotoxic agent were eligible for inclusion. Case-report forms were elaborated based on the patients' medical records from three Colombian hospitals.

[Hansen disease, an emergent condition in Chile].

Hansen's disease (HD) is caused by Mycobacterium leprae. It has a chronic course and preferentially affects the skin and the peripheral nerves. It's an emergent infection in Chile due to migration waves.

Effect of Maternal ±Citalopram Exposure on P11 Expression and Neurogenesis in the Mouse Fetal Brain.

Fetal exposure to selective serotonin reuptake inhibitors (SSRI) has been associated with increased risk of adverse neurodevelopmental outcomes. In the adult brain, SSRI therapy regulates p11 (s100a10) expression and alters neurogenesis. The protein p11 indirectly regulates 5-HT signaling through 5-HT1B/D receptors.

SPI-9 of Salmonella enterica serovar Typhi is constituted by an operon positively regulated by RpoS and contributes to adherence to epithelial cells in culture.

The genomic island 9 (SPI-9) from Salmonella enterica serovar Typhi (S. Typhi) carries three ORFs (STY2876, STY2877, STY2878) presenting 98 % identity with a type 1 secretory apparatus (T1SS), and a single ORF (STY2875) similar to a large RTX-like protein exhibiting repeated Ig domains. BapA, the Salmonella enterica serovar Enteritidis orthologous to S.

Maternal Pharmacokinetics and Fetal Disposition of (±)-Citalopram during Mouse Pregnancy.

While selective-serotonin reuptake inhibitor (SSRI) antidepressants are commonly prescribed in the treatment of depression, their use during pregnancy leads to fetal drug exposures. According to recent reports, such exposures could affect fetal development and long-term offspring health. A central question is how pregnancy-induced physical and physiological changes in mothers, fetuses, and the placenta influence fetal SSRI exposures during gestation.

Placental serotonin: implications for the developmental effects of SSRIs and maternal depression.

In addition to its role in the pathophysiology of numerous psychiatric disorders, increasing evidence points to serotonin (5-HT) as a crucial molecule for the modulation of neurodevelopmental processes. Recent evidence indicates that the placenta is involved in the synthesis of 5-HT from maternally derived tryptophan (TRP). This gives rise to the possibility that genetic and environmental perturbations directly affecting placental TRP metabolism may lead to abnormal brain circuit wiring in the developing embryo, and therefore contribute to the developmental origin of psychiatric disorders.

IP3 production in the hypersensitive response of lemon seedlings against Alternaria alternata involves active protein tyrosine kinases but not a G-protein.

IP3 increase and de novo synthesis of scoparone are produced in the hypersensitive response (HR) of lemon seedlings against the fungus Alternaria alternata. To elucidate whether a G-protein and/or a protein tyrosine kinase (PTK) are involved in signal transduction leading to the production of such a defensive response, we studied the HR in this plant system after treatment with G-protein activators alone and PTK inhibitors in the presence of fungal conidia. No changes in the level of IP3 were detected in response to the treatment with the G-protein activators cholera toxin or mastoparan, although the HR was observed in response to these compounds as determined by the scoparone synthesis.
