The Odon device is an innovation intended to perform instrumental vaginal delivery presently under development. We present an evaluation of the feasibility and safety of delivery with early prototypes of this device from an early terminated clinical study.

[Use of scales in depression patients in clinical practice in Argentina].

Although depression is a treatable cause of suffering, disability and death, its identifcation and treatment continue to be a challenge in clinical practice and a severe problem for global public health. The main objective of this study was to investigate the frequency with which mental health professionals use scales to assess depressive patients in Argentina and to determine the reasons that constrain such practice. Between July and September 2012 a national survey was conducted by e-mail.

Association of candidate gene polymorphisms with clinical subtypes of preterm birth in a Latin American population.

BackgroundPreterm birth (PTB) is the leading cause of neonatal mortality and morbidity. PTB is often classified according to clinical presentation as follows: idiopathic (PTB-I), preterm premature rupture of membranes (PTB-PPROM), and medically induced (PTB-M). The aim of this study was to evaluate the associations between specific candidate genes and clinical subtypes of PTB.

Maternal and neonatal epidemiological features in clinical subtypes of preterm birth.

Objective: This study was designed to characterize and compare the maternal and newborn epidemiological characteristics through analysis of environmental factors, sociodemographic characteristics and clinical characteristics between the different clinical subtypes of preterm birth (PTB): Idiopathic (PTB-I), premature rupture of the membranes (PTB-PPROM) and medically indicated (PTB-M). The two subtypes PTB-I and PTB-PPROM grouped are called spontaneous preterm births (PTB-S).

Methods: A retrospective, observational study was conducted in 1.

Aims: To describe the frequency of depressive symptoms compatible with a postpartum depression diagnosis, the associated factors and the temporal stability.

Methods: During 2006-2007 398 hospitalized puerperal women who attended CEMIC were interviewed 5 days after childbirth using the Edinburgh Postnatal Depression Scale and a socio-demographic questionnaire. A logistic regression analysis was performed to identify associated factors with a positive screening.

Feasibility and safety study of a new device (Odón device) for assisted vaginal deliveries: study protocol.

Background: Intrapartum complications are responsible for approximately half of all maternal deaths, and two million stillbirth and neonatal deaths per year. Prolonged second stage of labour is associated with potentially fatal maternal complications such as haemorrhage and infection and it is a major cause of stillbirth and newborn morbidity and mortality. Currently, the three main options for managing prolonged second stage of labour are forceps, vacuum extractor and caesarean section.

Prenatal sonographic descriptions of anomalies were compared with those recorded at birth.

Role of cognitive reserve in progression from mild cognitive impairment to dementia.

Unlabelled: Cognitive reserve is the ability to optimize performance through differential recruitment of brain networks, which may reflect the use of alternative cognitive strategies.

Objectives: To identify factors related to cognitive reserve associated with progression from mild cognitive impairment (MCI) to degenerative dementia.

Methods: A cohort of 239 subjects with MCI (age: 72.

Mild behavioral impairment and risk of dementia: a prospective cohort study of 358 patients.

Background: Mild cognitive impairment (MCI) is a transitional state between normal aging and dementia, at least for some patients. Behavioral symptoms in MCI are associated with a higher risk of dementia, but their association with dementia risk in patients without MCI is unknown. Mild behavioral impairment (MBI) refers to a late-life syndrome with prominent psychiatric and related behavioral symptoms in the absence of prominent cognitive symptoms that may also be a dementia prodrome.
