FACTORS INFLUENCING ACHIEVEMENT OF LOW-DENSITY LIPOPROTEIN CHOLESTEROL GOALS IN MEXICO: THE INTERNATIONAL CHOLESTEROL MANAGEMENT PRACTICE STUDY.
The International Cholesterol Management Practice Study is a multinational collaborative effort to describe the effectiveness of the lipid-lowering therapy (LLT) as well as the main barriers to achieve the low-density lipoprotein cholesterol (LDL-C) goals. ⋯ Achievement of LDL-C goals is suboptimal in Mexico, especially in patients with the highest CV risk. The main barriers to achieve the goal are easily detectable. Implementation of LLT should be adapted to the patient's needs and profile.

Neutrophil extracellular traps (NETs) were described more than one decade ago, but recently, the interest in these structures has increased due to their involvement in cancer progression, cancer-related thrombosis, and development of metastasis. This protumoral role of NETs strengthens their potential as new prognostic markers of cancer.

Comparative Study
FASTING INSULIN AND ALANINE AMINO TRANSFERASE, BUT NOT FGF21, WERE INDEPENDENT PARAMETERS RELATED WITH IRISIN INCREMENT AFTER INTENSIVE AEROBIC EXERCISING.
Irisin is a protein cleaved from fibronectin type III domain-containing protein 5 and has been implicated in the beneficial effects of exercise. However, it is unknown which factors contribute to irisin increment after intensive exercising in humans. This study aimed to assess independent factors related with serum irisin after 2 weeks of supervised physical activity in young sedentary healthy women. ⋯ Serum irisin and FGF21 levels significantly increased after 2 weeks of supervised physical activity. However, only fasting insulin and ALT, but not FGF21, were independent parameters explaining irisin increment, mainly after moderate to vigorous exercising.

Observational Study
A MULTIVARIATE PROGNOSTIC SCORE FOR PREDICTING MORTALITY OF ACQUIRED IMMUNODEFICIENCY SYNDROME PATIENTS WITH HYPOXEMIC RESPIRATORY FAILURE AND PNEUMOCYSTIS JIROVECI PNEUMONIA.
Severe hypoxemic respiratory failure (SHRF) due to Pneumocystis jiroveci pneumonia (PJP) in AIDS patients represents the main cause of admission and mortality in respiratory intensive care units (RICUs) in low- and middle-income countries. ⋯ This scoring system is a potentially useful tool to assist clinicians, in low- and medium-income countries, in estimating the RICU and inhospital mortality risk in patients with HIV/AIDS and SHRF caused by PJP.

It is often unclear to the clinical investigator whether observational studies should be submitted to a research ethics committee (REC), mostly because, in general, no active or additional interventions are performed. Moreover, obtaining an informed consent under these circumstances may be challenging, either because these are very large epidemiological registries, or the subject may no longer be alive, is too ill to consent, or is impossible to contact after being discharged. ⋯ In this context, in addition to their main function as evaluators from an ethical, methodological, and regulatory point of view, the RECs serve as mediators between the research subjects, looking after their basic rights, and the investigator or institution, safeguarding them from both legal and unethical perils that the investigation could engage, by ensuring that all procedures are performed following the international standards of care for research. The aim of this manuscript is to provide information on each type of study and its risks, along with actions to prevent such risks, and the function of RECs in each type of study.
