Abstract
OBJECTIVE To identify the association between glycemia control with level of diabetes knowledge, diabetes education, and lifestyle variables in patients with type 2 diabetes. DESIGN Cross-sectional analytical study. SITE: Clinics of the Mexican Institute of Social Security (IMSS), Mexico. PARTICIPANTS Patients with type 2 diabetes. MAIN MEASUREMENTS Glycated hemoglobin (HbA1c), glucose, and lipid profile levels were measured from fasting venous blood samples. Assessment of disease knowledge was performed using the Diabetes Knowledge Questionnaire (DKQ-24). Systolic and diastolic blood pressure was measured. Weight and abdominal circumference were measured, as well as body composition using bioimpedance. Sociodemographic, clinical, and lifestyle variables were obtained. RESULTS A total of 297 patients were included, sixty-seven percent (67%) were women with a median of six years since the diagnosis of diabetes. Only 7% of patients had adequate diabetes knowledge, and 56% had regular knowledge. Patients with adequate diabetes knowledge had a lower body mass index (p=0.016), lower percentage of fat (p=0.008), and lower fat mass (p=0.018); followed a diet (p=0.004) and had received diabetes education (p=0.002), and to obtain information about their illness (p=0.001). Patients with low levels of diabetes knowledge had a higher risk of HbA1c≥7% (OR: 4.68; 95% CI: 1.48,14.86; p=0.009), as well as those who did not receive diabetes education (OR: 2.17; 95% CI: 1.21-3.90; p=0.009) and those who did not follow a diet (OR: 2.37; 95% CI: 1.01,5.55; p=0.046). CONCLUSION Inadequate knowledge of diabetes, lack of diabetes education, and dietary adherence are associated with poor glycemia control in patients with diabetes.

Effectiveness of App-Based Intervention to Improve Health Status of Sedentary Middle-Aged Males and Females. INTERNATIONAL JOURNAL OF ENVIRONMENTAL RESEARCH AND PUBLIC HEALTH 2022; 19:ijerph19105857. [PMID: 35627392 PMCID: PMC9141809 DOI: 10.3390/ijerph19105857] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 04/05/2022] [Revised: 05/09/2022] [Accepted: 05/10/2022] [Indexed: 01/27/2023]
Abstract
BACKGROUND Adherence to a nutritional program and physical activity are the fundamental aspects of treatment for weight loss and associated problems. Previous research has shown that self-monitoring using a mobile device improves self-management. METHODS A total of 35 subjects (40.6 ± 9.24 years) participated in the study. During the control period (3 months), they received physical exercise guidelines and a personalized nutritional program, with the aim of promoting health status. In the experimental period (3 months), there was also a connection between the physical world (health care processes) and the digital world (app). All participants had their body composition and cardiovascular variables measured. They also underwent calcaneal densitometry to determine bone quality. Descriptive statistics, correlations and analysis of variance were performed (by a researcher who was not involved in the data collection) to study the changes between before and after interventions, as well as to make a comparison between treatments. RESULTS The use of an app, in which there exist a prediction of the evolution, messages of results and advice, among others, mediated by the assistance of dietitians/nutritionists and sports scientists, had a positive impact on the improvement of health parameters, showing significant differences in all variables except troponin. CONCLUSIONS The combination of healthy habits with the use of the app provided benefits, improving health.

Abstract
BACKGROUND Coronavirus disease 2019 (COVID-19) causes a mild illness in most cases; forecasting COVID-19-associated mortality and the demand for hospital beds and ventilators are crucial for rationing countries' resources. OBJECTIVE To evaluate factors associated with the severity of COVID-19 in Mexico and to develop and validate a score to predict severity in patients with COVID-19 infection in Mexico. DESIGN Retrospective cohort. PARTICIPANTS We included 1,435,316 patients with COVID-19 included before the first vaccine application in Mexico; 725,289 (50.5%) were men; patient's mean age (standard deviation (SD)) was 43.9 (16.9) years; 21.7% of patients were considered severe COVID-19 because they were hospitalized, died or both. MAIN MEASURES We assessed demographic variables, smoking status, pregnancy, and comorbidities. Backward selection of variables was used to derive and validate a model to predict the severity of COVID-19. KEY RESULTS We developed a logistic regression model with 14 main variables, splines, and interactions that may predict the probability of COVID-19 severity (area under the curve for the validation cohort = 82.4%). CONCLUSIONS We developed a new model able to predict the severity of COVID-19 in Mexican patients. This model could be helpful in epidemiology and medical decisions.

Ther Adv Endocrinol Metab 2022; 13:20420188211072704. [PMID: 35070258 PMCID: PMC8777321 DOI: 10.1177/20420188211072704] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/15/2021] [Accepted: 12/17/2021] [Indexed: 12/15/2022] Open
Abstract
INTRODUCTION Currently, only glucocorticoids have proved to impact adverse outcomes in COVID-19. However, their risk/benefit balance remains inconclusive and populations' characteristics should be considered. OBJECTIVE The objective was to evaluate the real-life use of glucocorticoids in patients with severe COVID-19 hospitalized in a third-level referral center and to determine the type, accumulated doses, and the in-hospital outcomes related with their use. METHODS We evaluated a retrospective cohort of 737 patients with criteria for severe COVID-19 and a positive polymerase chain reaction (PCR) test for SARS-CoV-2. We extracted data for epidemiological analysis, medical history, and medications, as well as baseline laboratory tests. Data were analyzed using SPSS 21.0 and nonparametric tests, medians, and interquartile ranges (IQR). A p < 0.05 was considered significant. RESULTS A total of 65.3% were men, with a median age of 59 years (IQR 46-70) and a median of 10 days of hospital stay (IQR 6-16), more than 40% had diabetes, hypertension, and/or obesity, and 0.8% used steroids chronically. At the time of the study, 54.0% had been discharged due to improvement and 40.8% died. The most common treatment used was dexamethasone 6 mg/day/10 days (46.6%). Patients with a complete dexamethasone scheme [as proposed by the Randomized Evaluation of COVID-19 Therapy (RECOVERY) study] had a lower mortality risk [hazard ratio (HR) 0.441, 95% confidence interval (CI) 0.232-0.840] in comparison with patients with lower doses (HR 1.803, 95% CI 1.080-3.012). Patients with methylprednisolone or several steroids tended to have higher cumulative doses (equivalent to >675 mg of prednisolone). CONCLUSION The use of steroids in severe COVID-19 reduces mortality only at the dose proposed in the RECOVERY study in the younger population. No benefit of the use of steroids was observed in patients with older age or higher number of comorbidities.

Abstract
Dexamethasone implementation for COVID-19 management represented a milestone but data regarding its impact and safety have not been consistently reproduced. We aimed to evaluate in-hospital mortality before and after the implementation of corticosteroid treatment (CS-T) for severe and critical COVID-19. We conducted a cohort study that included patients admitted with severe and critical COVID-19. The primary outcome was death during hospitalization. Secondary outcomes included the length of stay (LOS), need for invasive mechanical ventilation (IMV), time to IMV initiation, IMV duration, and development of hospital-acquired infections (HAIs). Bivariate, multivariate, and propensity-score matching analysis were performed. Among 1540 patients, 688 (45%) received CS-T. Death was less frequent in the CS-T group (18 vs 31%, p < .01). Among patients on IMV, death was also less frequent in the CS-T group (25 vs 55%, p < .01). The median time to IMV was longer in the CS-T group (5 vs 3 days, p < .01). HAIs occurred more frequently in the CS-T group (20 vs 10%, p < .01). LOS, IMV, and IMV duration were similar between groups. Multivariate analysis revealed an independent association between CS-T and lower mortality (aOR 0.26, 95% CI 0.19-0.36, p < .001). Propensity-score matching analysis revealed that CS-T was independently associated with lower mortality (aOR 0.33, 95% CI 0.22-0.50, p < .01). Treatment with corticosteroids was associated with reduced in-hospital mortality among patients with severe and critical COVID-19, including those on IMV.

Abstract
Background The intervention in the Lifestyle Medicine Clinic from La Carlota Hospital gives an opportunity to assess the clinical effect of a healthy lifestyle in an inpatient setting with emphasis in a plant-based diet, supervised daily exercise, sleep hygiene, psychological and optional spiritual therapies. This work evaluated the effect of short-term therapy on biometrics and blood profiles’ risk factors for non-communicable diseases (NCDs). Methods Twenty-five patients were enrolled in the intervention, 12 for the 10-day intervention and 13 for the 21-day intervention. Results The intervention improved most of the NCDs risk factors for the 10-day intervention weight decreased by -4.3% (p < .001), BMI -4.1% (p < .001), SBP -16.3% (p = .002), DBP -11.8% (p = .004), fasting glucose -31.3% (p = .041), total cholesterol -12.8% (p < .001), LDL -13.9 (p = .017), triglycerides and HDL lack statistical significance, however, there was a reduction of -7.7% and -9% respectively. For the 21-day intervention weight decreased by -8.3% (p = .016), SBP -11.2% (p = .005), DBP -11.4% (p = .022), triglycerides -39.5% (p = .034), total cholesterol -23.6% (p < .000), HDL -14.7% (p = .038), LDL -27.3% p < .000), BMI and fasting glucose presented a -15.2% and -21.2% reduction respectively without statistical significance. Conclusion The present study confirms that short-term lifestyle interventions effectively reduce the risk factors associated with NCD’s.

Abstract
Introduction Obesity has been linked with an increased incidence of melanoma; however, there are few data about its impact on melanoma prognosis. We aimed to determine if there is an association between body mass index (BMI) and overall survival (OS) in 707 patients with melanoma. Material and methods A retrospective study of 707 patients with melanoma collected consecutively from 2005 to 2015 with a diagnosis of melanoma, who were been diagnosed and treated in our institution and who had clinical follow-up was carried out. Survival analysis was performed comparing patients according to their BMI. Results In a multivariate analysis, factors influencing the 5-year OS were a positive margin (HR = 3.475, 95% CI: 1.829–6.600), the clinical-stage (HR = 2.565, 95% CI: 2.020–3.257, per switch to the upper stage), ulceration (HR = 3.475, 95% CI: 1.829–6.600), and BMI (HR .905, p = 0.018 for the overweight group; HR = 0.663, p = 0.021 for obesity grade I). Conclusions Patients who had a BMI between 25 and 34.9 kg/m2 had better survival.

Abstract
Immigration can improve economic status and access to education compared to the country of origin, but it challenges access to health and preventive care. Assess Brazilian immigrants' overall health conditions and dietary intake in New Jersey (US). This pilot study assessed health conditions and dietary intake. Brazilians immigrants were interviewed through their communities. Trained dietitians interviewed them using a questionnaire and three days of 24H recall. Dietary intake was analyzed using the Nutrition Data System for Research software. A sample of 118 individuals completed the protocol, majority female and overweight/obese, living in the US for 11.3 years with 21.1% declaring having Noncommunicable Diseases. The average number of daily meals was 2.20 ± 1.04. Energy intake does not correlate with time in the US. Obesity, dyslipidemia, and hypertension are the most prevalent Noncommunicable Diseases, demanding interventions that include managing saturated fat, cholesterol, and sodium intake.

Abstract
Background The first case of coronavirus 2019 (COVID-19) in Latin America was detected on February 26th, 2020, in Brazil. Later, in June, the World Health Organization announced that the focus of the outbreak had shifted to Latin America, where countries already had poor control of indicators of noncommunicable diseases (NCDs). Concerns about coronavirus infection led to a reduced number of visits and hospitalizations in patients with NCDs, such as cardiovascular disease, diabetes, and cancer. There is a need to determine the impact of the COVID-19 pandemic on patients who have cardiometabolic diseases but do not have clinical evidence of COVID-19 infection. Methods The CorCOVID LATAM is a cross-sectional survey of ambulatory cardiometabolic patients with no history or evidence of COVID-19 infection. The study will be conducted by the Interamerican Society of Cardiology. An online survey composed of 38 questions using Google Forms will be distributed to patients of 13 Latin American Spanish-speaking countries from June 15th to July 15th, 2020. Data will be analyzed by country and regions. Seven clusters of questions will be analyzed: demographics, socioeconomic and educational level, cardiometabolic profile, lifestyle and habits, body-weight perception, medical follow-up and treatments, and psychological symptoms. Results Final results will be available upon completion of the study. Conclusions The present study will provide answers regarding the impact of the COVID-19 pandemic on noninfected cardiometabolic patients. Data on this topic are scarce, as it is an unprecedented threat, without short-term solutions.

Abstract
BACKGROUND Hemodynamic response to supplemental oxygen in idiopathic pulmonary fibrosis (IPF) is still not well known. OBJECTIVE To determine and compare the effect of low-flow acute supplemental oxygen on the hemodynamics of IPF patients and matched healthy subjects. METHODS Descriptive and comparative study in 20 IPF-patients and 19 Control-subjects, (60-80 years old) breathing ambient air followed by acute nasal low-flow (3 L/min) supplemental oxygen. Non-invasive methods were used during the supine position to evaluate oxygen saturation, heart rate, stroke volume index, cardiac output index, total peripheral resistance and arterial blood pressure. RESULTS Breathing ambient air, IPF (vs. Control) presented lower values in stroke volume index (38.7 [29.4-43.2] vs. 45.4 [38.4-50.9] mL•kg-1•m2; p=0.009) and cardiac output index (2.484 [2.268 - 2.946] vs. 2.857 [2.628 - 3.054] L•min-1•m-2; p=0.028), with higher total peripheral resistance (1644 [1559-2076] vs. 1505 [1366-1784] dyne•s•cm-5; p=0.017). During supplemental oxygen (vs. ambient air), both groups increased oxygen saturation above 94% (p<0.001) while heart rate decreased about 6 to 8% (p<0.001); stroke volume index increased around 7% in the Control-group (p=0.004) but only 1% in the IPF-group (p=0.017). In addition, IPF showed increments in total peripheral resistance (1644 [1559-2076] vs. 1706 [1554-2278] dyne•s•cm-5; p=0.017) with subsequent decrements in cardiac output index (2.484 [2.268 - 2.946] vs. 2.362 [2.139 - 2.664] L•min-1•m-2; p<0.001). CONCLUSION Low-flow acute supplemental oxygen in IPF causes a meaningful decrement in cardiac output due to greater reduction in heart rate and increment in total peripheral resistance than matched healthy subjects. Knowing the hemodynamic profile of IPF patients may be helpful in determining their management with supplemental oxygen.

BACKGROUND Non-communicable diseases, such as obesity, diabetes, and hypertension, can be prevented and treated through a balanced nutrient-rich diet. Nutrition labels have been recognized as crucial to preventing obesity and non-communicable diseases through a healthier diet. OBJECTIVE Our aim was to examine the association between nutrition label use and chronic conditions (overweight, obesity, previously diagnosed diabetes, and hypertension) among an adult Mexican population. DESIGN This was a cross-sectional study that used data from the Mexican National Health and Nutrition Survey of 2016 (ENSANUT MC 2016). PARTICIPANTS/SETTING The participants were 5,013 adults aged 20 to 70 years old. Older adults (>70 years), illiterate participants, pregnant women, and participants with implausible blood pressure data were excluded from the sample. The survey was conducted from May to August 2016 in the participants' households. MAIN OUTCOME MEASURES We measured chronic conditions (overweight, obesity, previously diagnosed diabetes, and hypertension). STATISTICAL ANALYSES PERFORMED Pearson χ2 test was used to examine the associations among the use of nutrition labels and sociodemographic characteristics and chronic conditions. Multiple logistic regression was used to determine the association between nutrition label use and chronic conditions adjusting for the effect of confounding variables like sex, age, body mass index, education level, marital status, ethnicity, residence area, region, and socioeconomic status. RESULTS From the total sample, 40.9% (95% CI 38.4% to 43.8%) reported using nutrition labeling. Respondents with overweight or obesity were less likely to use nutrition labels (odds ratio 0.74; P<0.05). Participants who self-reported diabetes had significantly lower odds of nutrition label use than participants who did not report to have diabetes (odds ratio 0.66; P<0.05). Participants having 3 chronic conditions had lower odds of nutrition label use (odds ratio 0.34; P<0.01) relative to having zero chronic conditions. CONCLUSIONS This study suggests an association between nutrition label use and chronic conditions (obesity and diabetes). These findings demonstrate that people with obesity, diabetes, and a combination of chronic conditions were less likely to use nutrition labels than people without these conditions.

Protein Expression Profile of Twenty-Week-Old Diabetic db/db and Non-Diabetic Mice Livers: A Proteomic and Bioinformatic Analysis. Biomolecules 2018; 8:biom8020035. [PMID: 29857581 PMCID: PMC6023011 DOI: 10.3390/biom8020035] [Citation(s) in RCA: 9] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/13/2018] [Revised: 05/27/2018] [Accepted: 05/29/2018] [Indexed: 02/08/2023] Open
Abstract
Type 2 diabetes mellitus is characterized by insulin resistance in the liver. Insulin is not only involved in carbohydrate metabolism, it also regulates protein synthesis. This work describes the expression of proteins in the liver of a diabetic mouse and identifies the metabolic pathways involved. Twenty-week-old diabetic db/db mice were hepatectomized, after which proteins were separated by 2D-Polyacrylamide Gel Electrophoresis (2D-PAGE). Spots varying in intensity were analyzed using mass spectrometry, and biological function was assigned by the Database for Annotation, Visualization and Integrated Discovery (DAVID) software. A differential expression of 26 proteins was identified; among these were arginase-1, pyruvate carboxylase, peroxiredoxin-1, regucalcin, and sorbitol dehydrogenase. Bioinformatics analysis indicated that many of these proteins are mitochondrial and participate in metabolic pathways, such as the citrate cycle, the fructose and mannose metabolism, and glycolysis or gluconeogenesis. In addition, these proteins are related to oxidation⁻reduction reactions and molecular function of vitamin binding and amino acid metabolism. In conclusion, the proteomic profile of the liver of diabetic mouse db/db exhibited mainly alterations in the metabolism of carbohydrates and nitrogen. These differences illustrate the heterogeneity of diabetes in its different stages and under different conditions and highlights the need to improve treatments for this disease.
