[COVID-19 fatality rate conditioned by risk factors in Mexico in 2020].

Background: The COVID-19 fatality rate exhibited significant variations during the first year of the pandemic, and such divergences seem to show different levels of risk of death among populations. Very few studies stratified fatality based on the presence or absence of risk factors.

Objective: To identify COVID-19 fatality rates conditioned by risk factors.

ABO blood groups are not associated to gestational diabetes mellitus in Mexican women.

Objectives: Some studies show an increased risk of gestational diabetes mellitus for ABO blood groups. Others find a lower risk or do not identify any association. Inconsistencies may be due to the heterogeneity in the control for confounding variables.

Association between ABO blood groups and preeclampsia.

Objective: To determine the association between the ABO blood group and preeclampsia.

Methods: This is a case-control study that included patients with ( = 253) and without ( = 457) preeclampsia/eclampsia in Northeastern Mexico. Data were obtained from electronic medical records.

Cessation of Face Mask Use after COVID-19 Vaccination in Patients with Diabetes: Prevalence and Determinants.

Studies on the cessation of face mask use after a COVID-19 vaccine in patients with diabetes are not available, despite their greater predisposition to complications. We estimated the prevalence of cessation of face mask use after receiving the COVID-19 vaccine in patients with diabetes and identified which factor was most strongly associated with non-use. This was a cross-sectional study in patients with diabetes 18-70 years with at least one dose of vaccine against COVID-19 ( = 288).

Anthropometric parameters to estimate body frame size in children and adolescents: A systematic review.

Objective: To determine the most frequently body frame size (BFS) measurement and to compare the cut-off values used for classifying body size in children and adolescents.

Methods: This systematic review focused on primary studies and scientific reports published in Medline Ovid, EMBASE, Web of Science, or Scopus between January 1, 2007 and March 31, 2021. Eligible studies must have included at least one BFS parameter measured in healthy children or adolescents.

Multiple Unhealthy Behaviors Share Equivalent Profiles of Readiness for Change in Patients with Type 2 Diabetes.

Few studies have considered more than one behavior, despite the tendency towards multiple behaviors, and there are none that have focused on a Latino population. We determined the concurrence of four unhealthy behaviors related to glycemic control and identified common cognitive factors at advanced stages of readiness for change in patients with type 2 diabetes treated in primary care. A cross-sectional study was carried out during August-December 2018 in northeastern Mexico.

Acellular fraction from malignant effusions has cytotoxicity in breast cancer cells.

Malignant ascites (MA) and malignant pleural effusion (MPE) are frequently developed in patients with metastatic cancer; however, the biological properties of these fluids have not been clarified. The present study explored the biological role of a low molecular fraction derived from malignant effusions on the activation of peripheral blood mononuclear cells and on the proliferation of breast cancer cells and fibroblast 55x cells. A <10-kDa fraction from effusions of 41 oncological patients and 34 individuals without cancer was purified, and its potential role in inhibiting nitric oxide (NO) production on lipopolysaccharide (LPS)-stimulated peripheral blood mononuclear cells was explored, as well as its cytotoxicity on MCF-7 breast cancer cells and fibroblast 55x cells.

Anti-inflammatory and antioxidant activity of essential amino acid α-ketoacid analogues against renal ischemia-reperfusion damage in Wistar rats.

Introduction: Essential amino acid α-keto acid analogs are used in the treatment of chronic kidney disease to delay the symptoms of uremia. However, it is unknown whether essential amino acid α-keto acid analogs affect the oxidative stress and the inflammation in acute renal injury such as those produced by ischemia-reperfusion.

Objective: To evaluate the effect of essential amino acid α-keto acid analogs on renal ischemia-reperfusion injury in Wistar rats.

Vitamin supplementation increases the virulence of grown axenically.

As a consequence of axenic growth and the elimination of accompanying bacterial flora, Entamoeba histolytica virulence decreases rapidly, and pathogenicity is lost. This paper evaluated the impact of vitamin supplementation on the pathogenicity of E. histolytica.

Metabolomic and biochemical characterization of a new model of the transition of acute kidney injury to chronic kidney disease induced by folic acid.

Background: Renal diseases represent a major public health problem. The demonstration that maladaptive repair of acute kidney injury (AKI) can lead to the development of chronic kidney disease (CKD) and end-stage renal disease has generated interest in studying the pathophysiological pathways involved. Animal models of AKI-CKD transition represent important tools to study this pathology.

[Ultrasound-guided umbilical venous catheterisation: A cost-effectiveness analysis].

Introduction: Although the use of ultrasound for the insertion of central catheters has proven to be cost-effective in adults, it is not known if this is the case in the neonatal population. This study compared the cost-effectiveness of ultrasound-guided umbilical venous catheterisation with conventional catheterisation in a neonatal intensive care unit of a Public University Hospital.

Patients And Methods: A retrospective observational study was conducted on newborns that required an umbilical venous catheter before completing their first 24hours of extra-uterine life.

Discriminatory Accuracy of Preeclampsia Risk Factors in Primary Care.

Background: Although it is common to use risk factors in the screening for preeclampsia, they do not always accurately identify patients who truly have this condition.

Aim Of The Study: To determine the discriminatory accuracy of known preeclampsia risk factors, both individually and in combination.

Methods: We studied patients undergoing prenatal care who were diagnosed with preeclampsia or eclampsia (n = 160 cases) in primary care and those who were not (n = 430 controls).

Comparison of the discriminatory accuracy of four risk criteria for preeclampsia.

Objectives: Several criteria have been proposed to categorize the risk of preeclampsia, with notable differences between these criteria. We compared the discriminatory accuracy of criteria for categorizing preeclampsia risk established by four institutions, namely, the World Health Organization (WHO), National Institute for Health and Care Excellence (NICE), American College of Obstetricians and Gynecologists (ACOG), and National Center for Technological Excellence in Health (CENETEC), and estimated the concordance between these criteria.

Study Design: We performed a secondary data analysis of 590 Mexican obstetric patients who received prenatal care in primary care between 2016 and 2017; 160 had a diagnosis of preeclampsia.

D-Lactate and intestinal fatty acid-binding protein are elevated in serum in patients with acute ischemic stroke.

Experimental studies suggest that the intestinal barrier is affected in ischemic stroke. D-Lactate and intestinal fatty acid-binding protein (IFABP) are markers of intestinal mucosa integrity and barrier function. Our purpose was to evaluate the serum concentrations of these markers in patients with acute ischemic stroke (AIS).

[Myocardial infarction in young mexicans associated to metabolic syndrome].

Background: Acute coronary diseases are catastrophic, especially in young patients.

Objective: To determine the risk of metabolic syndrome (MS) for premature acute myocardial infarction (AMI), combined with familial, behavioral, and nutritional factors in the northeast of Mexico.

Material And Methods: This is a case control study of patients less than 47 years of age with no personal history of angina, AMI, or cerebrovascular disease.

Body frame size in school children is related to the amount of adipose tissue in different depots but not to adipose distribution.

Objectives: The main aim of this study was to test the hypothesis that body frame size is related to the amount of fat in different adipose tissue depots and to fat distribution in schoolchildren.

Methods: Children aged between 5 and 10 years were included in this cross-sectional study (n = 565). Body frame size, adiposity markers (anthropometric, skinfolds thickness, and ultrasound measures), and fat distribution indices were analyzed.

Prevalence and Determinants of Repeat Mammography Among Women from a Developing Country.

Failures in repeat mammography decrease the potential benefits of screening; however, it is notable that the recent use of mammography is more frequently studied than repeat use. We estimated the prevalence and analyzed determinants for repeat mammography among women from Mexico, a developing country of Latin America. It was a two-stage study with an initial cross-sectional design (n = 1045) and a final case-control design that involved women of at least 45 years of age with no history of breast, ovarian, or uterine cancer.

[Not Available].

Background: The use of sagittal abdominal diameter (SAD) has been proposed for screening cardio-metabolic risk factors; however, its accuracy can be influenced by the choice of thresholds values.

Aim: To determine the SAD threshold values for cardio-metabolic risk factors in Mexican adults; to assess whether parallel and serial SAD testing can improve waist circumference (WC) sensitivity and specificity; and to analyze the effect of considering SAD along with WC and body mass index (BMI) in detecting cardio-metabolic risk.

Methods: This cross-sectional study was conducted during 2012-2014 in Northeast Mexico (n = 269).

An acidic sphingomyelinase Type C activity from Mycobacterium tuberculosis.

Sphingomyelinases (SMases) catalyze the hydrolysis of sphingomyelin to ceramide and phosphorylcholine. Sphingolipids are recognized as diverse and dynamic regulators of a multitude of cellular processes mediating cell cycle control, differentiation, stress response, cell migration, adhesion, and apoptosis. Bacterial SMases are virulence factors for several species of pathogens.

[Breast cancer in México: a 10-year trend analysis on incidence and age at diagnosis].

Introduction: Breast cancer is an important public health problem. Some countries have achieved a downward trend while in others, continues ascending. In México, information on incidence and age at diagnosis is isolated in time, and knowledge on trend analysis is lacking.

Gemfibrozil attenuates the inflammatory response and protects rats from abdominal sepsis.

Sepsis is a serious condition characterized by an infectious process that induces a severe systemic inflammatory response. In this study, the effects of gemfibrozil (GFZ) on the inflammatory response associated with abdominal sepsis were investigated using a rat model of cecal-ligation and puncture (CLP). Male Wistar rats were randomly divided into three groups: Sham-operated group (sham), where laparotomy was performed, the intestines were manipulated, and the cecum was ligated but not punctured; control group, subjected to CLP; and GFZ group, which received GFZ prior to undergoing CLP.
