Educational research on medical residency programs in Chile: a scoping review and analysis of the impact of the new accreditation policy.

Background: Accrediting medical specialties programs are expected to influence and standardize training program quality, align curriculum with population needs, and improve learning environments. Despite global agreement on its necessity, methods vary widely. In the Chilean context, a recent new accreditation criteria includes research productivity in relation to educational research on resident programs, so we aimed to define it.

Standardising intraoperative irrigation with 0.05% chlorhexidine gluconate in caesarean delivery to reduce surgical site infections: A single institution experience.

Background: Surgical site infection is a significant cause of morbidity and mortality following caesarean delivery.

Objective: To determine whether standardising intraoperative irrigation with 0.05% chlorhexidine gluconate during caesarean delivery could decrease infection rates.

[Early neonatal sepsis, incidence and associated risk factors in a public hospital in western Mexico].

Background: Early neonatal sepsis (EOS) is the second leading cause of death in the first week of life. Epidemiology differs in developed and developing countries.

Aim: To describe the epidemiology of EOS among newborn patients in a public hospital in western Mexico.

Characterization of nanostructured ZnO thin films deposited through vacuum evaporation.

This work presents a novel technique to deposit ZnO thin films through a metal vacuum evaporation technique using colloidal nanoparticles (average size of 30 nm), which were synthesized by our research group, as source. These thin films had a thickness between 45 and 123 nm as measured by profilometry. XRD patterns of the deposited thin films were obtained.

The smart aerial release machine, a universal system for applying the sterile insect technique.

Background: Beyond insecticides, alternative methods to control insect pests for agriculture and vectors of diseases are needed. Management strategies involving the mass-release of living control agents have been developed, including genetic control with sterile insects and biological control with parasitoids, for which aerial release of insects is often required. Aerial release in genetic control programmes often involves the use of chilled sterile insects, which can improve dispersal, survival and competitiveness of sterile males.

Isotope ratios of H, C, and O in CO2 and H2O of the martian atmosphere.

Stable isotope ratios of H, C, and O are powerful indicators of a wide variety of planetary geophysical processes, and for Mars they reveal the record of loss of its atmosphere and subsequent interactions with its surface such as carbonate formation. We report in situ measurements of the isotopic ratios of D/H and (18)O/(16)O in water and (13)C/(12)C, (18)O/(16)O, (17)O/(16)O, and (13)C(18)O/(12)C(16)O in carbon dioxide, made in the martian atmosphere at Gale Crater from the Curiosity rover using the Sample Analysis at Mars (SAM)'s tunable laser spectrometer (TLS). Comparison between our measurements in the modern atmosphere and those of martian meteorites such as ALH 84001 implies that the martian reservoirs of CO2 and H2O were largely established ~4 billion years ago, but that atmospheric loss or surface interaction may be still ongoing.

Phylogeny and systematics of Micranthes (Saxifragaceae): an appraisal in European territories.

Recent phylogenetic studies have shown that Saxifraga, as currently understood, must be divided into two genera: Saxifraga L. sensu stricto and Micranthes Haw. To better understand the evolutionary history of these two genera, we performed phylogenetic analyses inferred from the nuclear ribosomal sequences from the internal transcribed spacer and the sequences of the plastid DNA (rbcL).
