OBJETIVES: To describe the epidemiological characteristics and obstetric and perinatal outcomes in pregnant women after 40 years. DESIGN: Descriptive Study retrospectivo.MATERIAL AND METHODS: The medical records of all births occurred in women 40 years or older treated at the IME of January 1, 2004 to November 30, 2004. Revised RESULTS: 18568 births were attended, of which 516 were women aged 40 or more, with an incidence of 2.78%. Two groups, the group of gilts (n = 46) and the group of multiparous (n = 470) was distinguished. 58.2% were between 40 and 42 years at birth. Both groups had similar characteristics in terms of average age, marital status, BMI and number of prenatal visits. The cesarean rate in the entire population was high (56.8%) and highest in nulliparous group (71.7%; p <0.01). The group of gilts showed higher instances of dysfunctional births, in which oxytocin (52.2%;...

Records documenting the ingestion of plastic anthropogenic wastes in marine mammals are almost non-existent in the Eastern Pacifi c. In the present work, the ingestion of a plastic net by the South American sea lion Otaria fl avescens (Shaw, 1800) in the “San Pedro” Beach, Lurín, Lima, Peru is reported. Necropsy of the specimen showed the presence of whitish plastic fi laments (nylon) (≈ 0.5 mm in diameter) intermixed with individuals of Mugil cephalus Linnaeus, 1758. Previous documentation in research/dissemination articles on ingestion of plastic anthropic macro-waste in this species in Peru has not been reported, nor in articles of international review. With this new report, 42.85% (n = 6) of the otarid species around the world have ingested plastic macro-waste.

In the present contribution, two nationwide surveys of personal protective equipment (PPE) pollution were conducted in Peru and Argentina aiming to provide valuable information regarding the abundance and distribution of PPE in coastal sites. Additionally, PPE items were recovered from the environment and analyzed by Fourier transformed infrared (FTIR) spectroscopy, Scanning electron microscopy (SEM) with Energy dispersive X-ray (EDX), and X-ray diffraction (XRD), and compared to brand-new PPE in order to investigate the chemical and structural degradation of PPE in the environment. PPE density (PPE m− 2 ) found in both countries were comparable to previous studies. FTIR analysis revealed multiple polymer types comprising common PPE, mainly polypropylene, polyamide, polyethylene terephthalate, and polyester. SEM micrographs showed clear weathering signs, such as cracks, cavities, and r...
