Doxycycline Prevents Preclinical Atherosclerosis, Pancreatic Islet Loss and Improves Insulin Secretion after Glycemic Stimulation: Preclinical Study in Individuals with a High-Fat Diet.

Doxycycline (Doxy) is an antibiotic, which has exhibited anti-inflammatory activity and glucose metabolism improvement. The present study was proposed to evaluate its effects on glucose metabolism and other associated processes, such as lipemia and adipogenesis, as well as, to evaluate its effects on the liver, pancreas, and aorta in subjects fed with an occidental high-fat diet (HFD). The trial followed three groups of BALB/c mice for 6 months: (1) Standard diet (SD); (2) HFD-placebo (saline solution); and (3) HFD-Doxy (10 mg/kg/day).

Using Artificial Intelligence to Develop a Multivariate Model with a Machine Learning Model to Predict Complications in Mexican Diabetic Patients without Arterial Hypertension (National Nested Case-Control Study): Metformin and Elevated Normal Blood Pressure Are Risk Factors, and Obesity Is Protective.

Diabetes mellitus is a disease with no cure that can cause complications and even death. Moreover, over time, it will lead to chronic complications. Predictive models have been used to identify people with a tendency to develop diabetes mellitus.

Protective Effect of Neutral Electrolyzed Saline on Gentamicin-Induced Nephrotoxicity: Evaluation of Histopathologic Parameters in a Murine Model.

: Gentamicin (GM) is a nephrotoxic aminoglycoside. Neutral electrolyzed saline (SES) is a compound with anti-inflammatory, antioxidant, and immunomodulatory properties. The objective of the present study was to evaluate whether kidney damage by GM can be prevented and/or reversed through the administration of SES.

Evaluation of Medical Care for Diabetic and Hypertensive Patients in Primary Care in Mexico: Observational Retrospective Study.

Introduction: The present study evaluated the quality of medical care for patients diagnosed with diabetes mellitus (DM), hypertension (HBP), and both pathologies (DM+HBP) within a public health system in Mexico.

Methods: 45,498 patients were included from 2012 to 2015. All information was taken from the electronic medical record database.

Factors associated with increased odds of sensorineural hearing loss in infants exposed to the Zika virus during pregnancy.

Introduction: The Zika virus (ZIKV) infection in pregnant women has been associated with an increased risk of birth defects. We aimed to estimate the prevalence of sensorineural hearing loss (SNHL) in infants exposed to the ZIKV during their gestation and evaluate the factors associated with its increased odds.

Methodology: A cross-sectional study was performed from July 2016 to June 2019 in a Western state of Mexico and data from 61 infants that presented with laboratory-positive (RT-qPCR) evidence of in utero exposure to ZIKV were analyzed.

A novel cell-free formulation for the treatment of knee osteoarthritis generates better patient-reported health outcomes in more severe cases.

Background: The bioactive cell-free formulation (BIOF2) for cartilage regeneration has shown a major therapeutic response in severe knee osteoarthritis. However, its effect on patients with mild or moderate stages of the disease has not been studied.

Objective: To evaluate the Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) score, minimal clinically important improvement (MCII) and sleep disturbances in mild, moderate, and severe stages of knee osteoarthritis (OA) with the novel cell-free formulation treatment (BIOF2).

Death related to Cedecea lapagei in a soft tissue bullae infection: a case report.

Background: Cedecea lapagei bacterium was discovered in 1977 but was not known to be pathogenic to humans until 2006. In the medical literature there are very few clinical case reports of Cedecea lapagei; none have reported a catastrophic death secondary to a soft tissue hemorrhagic bullae infection. As well as soft tissue infection, rare cases of pneumonia, urinary tract infections, peritonitis, osteomyelitis, bacteremia, and sepsis have been documented with the majority having good outcomes.

Association Between Nonalcoholic Fatty Liver Disease and Severe Male Reproductive Organ Impairment (Germinal Epithelial Loss): Study on a Mouse Model and on Human Patients.

Metabolic syndrome (MS) has been associated with testicular damage. Nonalcoholic fatty liver disease (NAFLD) is a multisystemic disease that affects different organs, but its effect on the testes is unknown. A study analyzing germ cell involvement on BALB/c mice was carried out.

Smoking and female sex as key risk factors associated with severe arthralgia in acute and chronic phases of Chikungunya virus infection.

Arthralgia is a potentially incapacitating condition and a persistent symptom in chronic or acute episodes of Chikungunya fever caused by infection with the Chikungunya virus (CHIKV). To the best of our knowledge, there are no reports on risk factors associated with the intensity of arthralgias in typical acute episodes of the disease. Although a number of studies have reported on risk factors associated with the development of the chronic stage of the disease, smoking habits have not been analyzed.

Topical 5% potassium permanganate solution accelerates the healing process in chronic diabetic foot ulcers.

Potassium permanganate has been reported to be an effective treatment for certain types of wounds. The aim of the present study was to evaluate the use of potassium permanganate in the treatment of diabetic foot ulcers. A single-blind, randomized, controlled clinical trial was conducted on patients with type 2 diabetes mellitus that presented with a foot ulcer persisting for >3 months.

Preclinical trial on the use of doxycycline for the treatment of adenocarcinoma of the duodenum.

Adenocarcinoma of the duodenum comprises 50-70% of duodenal tumors. There is an increase in extracellular matrix metalloproteinases in this disease and it has been suggested that they play an important role in the development and pathology. Therefore, new therapeutic recommendations based on inhibitors of these enzymes, such as doxycycline, are under investigation.

Preclinical analysis of nonsteroidal anti-inflammatory drug usefulness for the simultaneous prevention of steatohepatitis, atherosclerosis and hyperlipidemia.

Nonalcoholic steatohepatitis (NASH) is currently one of the primary liver diseases. Recent studies have shown a clinical relation between NASH and atherosclerosis. There is much interest in these two diseases because they are both associated with great morbidity and mortality.

The D9N, N291S, and T495G Polymorphisms of the Lipoprotein Lipase Gene Are Not Associated with Cerebral Infarction.

Background: Lipoprotein lipase (LPL) plays an important role in plasma lipoprotein metabolism and its polymorphisms are possibly implicated in the etiology of ischemic cerebrovascular disease (CVD). The aim of this work was to determine the association of the of D9N, N291S, and T495G polymorphisms of the LPL gene as a risk factor for the development of CVD.

Methods: A case-control study was conducted that included 100 patients with CVD and 120 healthy controls.
