Metal Contents in Feathers from Birds (Rhynchopsitta terrisi, and Columba livia) with Different Ecological Niches.

The metal contaminants can be utilized as an ecological tool to analyze niche partition in birds. As environmental contamination biological indicators, essential (Zn, Cu, and Cr) and non-essential (Pb and Cd) metals in the flight feathers of the Maroon-fronted Parrot and Pigeon with different ecological niches were assessed. The feathers of the parrot were gathered at a national park (Parque Nacional Cumbres de Monterrey) and the feathers of pigeons were collected at an urban site, that is, the city of Monterrey, Mexico.

Nonalcoholic Fatty Liver Disease Severity Is Related to Plasma Pro-Oxidative Biomarkers Rather Than Liver Tissue-Measured Nitrogen Metabolism Biomarkers in Population with Obesity and Metabolic Syndrome.

The metabolic syndrome (MS) is associated with an increased production of nitrogen metabolites and elevated oxidative stress, which favors progression of nonalcoholic fatty liver disease (NAFLD). Subjects with the phenotype known as metabolically unhealthy obese (MUO) meet most of the MS cardiometabolic risk criteria and show a higher risk of advanced NAFLD severity, compared with the so-widely known metabolically healthy obese (MHO). Obese individuals with MS are more susceptible to abnormal lipid accumulation in different tissues, whereas oxidative stress and nitrogen metabolites are increased in MS and/or obesity.

[Laboratories as predictors of length of hospital stay in patients with pneumonia].

Background: There are several factors that influence the length of hospital stay (LoHS) in patients with community-acquired pneumonia (CAP). There is currently no study in the literature that correlates laboratory parameters at hospital admittance with the LoHS.

Objective: To find the association of laboratory parameters with the LoHS in patients with community-acquired pneumonia.

[Work engagement and burnout syndrome in a secondary care level during the COVID pandemic in Mexico, 2021].

Background: The coronavirus disease 2019 (COVID-19) was declared a pandemic on March 11, 2020. The health personnel were the first line of action, so detecting the presence of burnout and work engagement allows us to have an overview of the perspective on the work environment of these workers.

[Diagnosis of SCIWORA associated with Brown Séquard syndrome in an adolescent].

SCIWORA (Spinal Cord Injury without Radiologic Abnormality) is a rare condition that mainly affects pediatric patients; We present the case of a teenage male patient diagnosed with SCIWORA/Brown Séquard Syndrome. In admission, he has multiple bruises on his neck and right hemibody and immediately he refers paraesthesia in all four limbs and spastic hemiparesis with right predominance, as well as inability to stand up and urinary continence. Treatment based on NASCIS III study is initiated and after the imaging tests, a diagnosis has already been made.

Background: An ankle/arm index < 0.90 and ≥ 1.41 is considered as abnormal.

[Prevalence and risk factors associated with intestinal parasitoses in pregnant women and their relation to the infant's birth weight].

Objective: To determine the prevalence and the risk factors associated with intestinal parasitosis in pregnant women and the relation with the newborns.

Material And Methods: A transversal analytical study. 207 women were selected and a guided survey was applied.

[Prevalence of breast self-examination in health workers. Factors associated with its correct performance].

Objective: Determine the frequency of a breast self-examination (BSE), in health workers and the associated risk factors in its correct performance.

Material And Methods: From January 24 to February 24, 2000, a transversal analytical study was performed in the workers of the General Hospital Zone number 32, of the IMSS in Minatitlán, Veracruz. 106 women were included, who verbally accepted to participate in the study.

[Prenatal diagnosis of fetal ovarian cyst, postnatal spontaneous remission].

Unlabelled: Prenatal diagnosis of fetal ovarian cyst, spontaneously resolved in the postnatal period.

Introduction: Fetal ovarian cysts are an unusual entity, which is generally discovered during an ultrasonographic fetal examination. The objective of this report is to present a clinical case of a female fetus with an ovarian cysts which was diagnose by an ultrasound (US) at 36.

[Clinical competence in systemic arterial hypertension of undergraduate students at 2 schools of medicine].

Objectives: A) To develop and validate a questionnaire for exploring clinical competence of medical students in Hypertensive Vascular Disease. B) To know and compare clinical competence among medical students of two medical schools, who are about to be caring for hypertensive patients.

Design: Cross-sectional study.

[Bilateral renal agenesis (Potter's syndrome) in a girl born to a hyperthyroid mother who received methimazole in early pregnancy].

Bilateral kidney agenesias (Potter syndrome) in a newborn of a hyperthyroid woman receiving methimazole during early pregnancy. This is a clinical case of a hyperthyroid woman that received methimazole during early pregnancy who gave birth to a girl with bilateral kidney agenesis. The initial clinical data was the presence of oligohydramnios detected by an ultrasound (US) at 19 gestational weeks.

[Effectiveness and safety of mebendazole compared to nitazoxanide in the treatment of Giardia lamblia in children].

Objective: Compare the effectiveness and safety of mebendazole versus nitazoxanide in the treatment of Giardia lamblia in children. Giardiasis is an intestinal protozoan of worldwide distribution which most frequently affects the infantile population. In Mexico we have, found a frequency of three to sixty percent.

[Prenatal diagnosis of type II osteogenesis imperfecta].

We present one case of a 23 week old fetus that was diagnosed with osteogenesis imperfecta type II via ultrasound, The principal ultrasonographic findings were; lack of mineralization in the calvaria, short, wide, and angulated femurs, with the presence of fractures, the length corresponds to a 17.5 week old gestation, more than two standard deviations below the mean for gestational age. The rest of the long bones show fractures and poor mineralization that was suggested by reduced acoustic shadowing.
