Zinc associated nanomaterials and their intervention in emerging respiratory viruses: Journey to the field of biomedicine and biomaterials.

Respiratory viruses represent a severe public health risk worldwide, and the research contribution to tackle the current pandemic caused by the SARS-CoV-2 is one of the main targets among the scientific community. In this regard, experts from different fields have gathered to confront this catastrophic pandemic. This review illustrates how nanotechnology intervention could be valuable in solving this difficult situation, and the state of the art of Zn-based nanostructures are discussed in detail. For virus detection, learning from the experience of other respiratory viruses such as influenza, the potential use of Zn nanomaterials as suitable sensing platforms to recognize the S1 spike protein in SARS-CoV-2 are shown. Furthermore, a discussion about the antiviral mechanisms reported for ZnO nanostructures is included, which can help develop surface disinfectants and protective coatings. At the same time, the properties of Zn-based materials as supplements for reducing viral activity and the recovery of infected patients are illustrated. Within the scope of noble adjuvants to improve the immune response, the ZnO NPs properties as immunomodulators are explained, and potential prototypes of nanoengineered particles with metallic cations (like Zn2+) are suggested. Therefore, using Zn-associated nanomaterials from detection to disinfection, supplementation, and immunomodulation opens a wide area of opportunities to combat these emerging respiratory viruses. Finally, the attractive properties of these nanomaterials can be extrapolated to new clinical challenges.

Aspects of Multicomponent Integrated Care Promote Sustained Improvement in Surrogate Clinical Outcomes: A Systematic Review and Meta-analysis.

OBJECTIVE: The implementation of the Chronic Care Model (CCM) improves health care quality. We examined the sustained effectiveness of multicomponent integrated care in type 2 diabetes. RESEARCH DESIGN AND METHODS: We searched PubMed and Ovid MEDLINE (January 2000-August 2016) and identified randomized controlled trials comprising two or more quality improvement strategies from two or more domains (health system, health care providers, or patients) lasting ≥12 months with one or more clinical outcomes. Two reviewers extracted data and appraised the reporting quality. RESULTS: In a meta-analysis of 181 trials (N = 135,112), random-effects modeling revealed pooled mean differences in HbA1c of -0.28% (95% CI -0.35 to -0.21) (-3.1 mmol/mol [-3.9 to -2.3]), in systolic blood pressure (SBP) of -2.3 mmHg (-3.1 to -1.4), in diastolic blood pressure (DBP) of -1.1 mmHg (-1.5 to -0.6), and in LDL cholesterol (LDL-C) of -0.14 mmol/L (-0.21 to -0.07), with greater effects in patients with LDL-C ≥3.4 mmol/L (-0.31 vs. -0.10 mmol/L for <3.4 mmol/L; Pdifference = 0.013), studies from Asia (HbA1c -0.51% vs. -0.23% for North America [-5.5 vs. -2.5 mmol/mol]; Pdifference = 0.046), and studies lasting >12 months (SBP -3.4 vs. -1.4 mmHg, Pdifference = 0.034; DBP -1.7 vs. -0.7 mmHg, Pdifference = 0.047; LDL-C -0.21 vs. -0.07 mmol/L for 12-month studies, Pdifference = 0.049). Patients with median age <60 years had greater HbA1c reduction (-0.35% vs. -0.18% for ≥60 years [-3.8 vs. -2.0 mmol/mol]; Pdifference = 0.029). Team change, patient education/self-management, and improved patient-provider communication had the largest effect sizes (0.28-0.36% [3.0-3.9 mmol/mol]). CONCLUSIONS: Despite the small effect size of multicomponent integrated care (in part attenuated by good background care), team-based care with better information flow may improve patient-provider communication and self-management in patients who are young, with suboptimal control, and in low-resource settings.

Pooling and expanding registries of familial hypercholesterolaemia to assess gaps in care and improve disease management and outcomes: Rationale and design of the global EAS Familial Hypercholesterolaemia Studies Collaboration.

BACKGROUND: The potential for global collaborations to better inform public health policy regarding major non-communicable diseases has been successfully demonstrated by several large-scale international consortia. However, the true public health impact of familial hypercholesterolaemia (FH), a common genetic disorder associated with premature cardiovascular disease, is yet to be reliably ascertained using similar approaches. The European Atherosclerosis Society FH Studies Collaboration (EAS FHSC) is a new initiative of international stakeholders which will help establish a global FH registry to generate large-scale, robust data on the burden of FH worldwide. METHODS: The EAS FHSC will maximise the potential exploitation of currently available and future FH data (retrospective and prospective) by bringing together regional/national/international data sources with access to individuals with a clinical and/or genetic diagnosis of heterozygous or homozygous FH. A novel bespoke electronic platform and FH Data Warehouse will be developed to allow secure data sharing, validation, cleaning, pooling, harmonisation and analysis irrespective of the source or format. Standard statistical procedures will allow us to investigate cross-sectional associations, patterns of real-world practice, trends over time, and analyse risk and outcomes (e.g. cardiovascular outcomes, all-cause death), accounting for potential confounders and subgroup effects. CONCLUSIONS: The EAS FHSC represents an excellent opportunity to integrate individual efforts across the world to tackle the global burden of FH. The information garnered from the registry will help reduce gaps in knowledge, inform best practices, assist in clinical trials design, support clinical guidelines and policies development, and ultimately improve the care of FH patients.

[Drink consumption for a healthy life: recommendations for the general population in Mexico]. / Consumo de bebidas para una vida saludable: recomendaciones para la población mexicana.

The Expert Committee in charge of developing the Beverage Consumption Recommendations for the Mexican Population was convened by the Ministry of Health with the aim of drafting evidence-based guidelines for consumers, health professionals, and government officials. The prevalence of overweight, obesity and diabetes have dramatically increased in Mexico; beverages contribute a fifth of all calories consumed by Mexicans. Extensive research has documented that caloric beverages increase the risk of obesity. Taking into consideration multiple factors, including health benefits, risks, and nutritional implications associated with beverage consumption, as well as consumption patterns in Mexico, the committee classified beverages in six categories. Classifications were made based on caloric content, nutritional value, and health risks associated with the consumption of each type of beverage. Ranges included healthier (level 1) to least healthy (level 6) options as follows: Level 1: water; Level 2: skim or low fat (1%) milk and sugar free soy beverages; Level 3: coffee and tea without sugar; Level 4: non-caloric beverages with artificial sweeteners; Level 5: beverages with high caloric content and limited health benefits (fruit juices, whole milk, and fruit smoothies with sugar or honey; alcoholic and sports drinks), and Level 6: beverages high in sugar and with low nutritional value (soft drinks and other beverages with significant amounts of added sugar like juices, flavored waters, coffee and tea). The committee recommends the consumption of water as a first choice, followed by no or low-calorie drinks, and skim milk. These beverages should be favored over beverages with high caloric value or sweetened beverages, including those containing artificial sweeteners. Portion size recommendations are included for each beverage category together with healthy consumption patterns for men and women.

Consumo de bebidas para una vida saludable: recomendaciones para la población mexicana / Drink consumption for a healthy life: recommendations for the general population in Mexico

El Secretario de Salud convocó al Comité de Expertos para la elaboración de las “Recomendaciones sobre el consumo de bebidas para la población mexicana”; la finalidad fue desarrollar lineamientos basados en evidencia científica para los consumidores, los profesionales de la salud y el sector gubernamental. Las prevalencias de sobrepeso, obesidad y diabetes han aumentado con rapidez en México y las bebidas representan la quinta parte de la energía que consumen los mexicanos. La evidencia señala que las bebidas con aporte energético incrementan el riesgo de obesidad. Considerando los beneficios y riesgos para la salud y nutrición, así como el patrón de consumo de las bebidas en México, el Comité clasificó las bebidas en seis categorías de acuerdo con su contenido energético, valor nutricio y riesgos a la salud, en una escala que clasifica las bebidas de la más (nivel 1) a la menos (nivel 6) saludable. Nivel 1: agua potable; nivel 2: leche baja en grasa (1%) y sin grasa y bebidas de soya sin azúcar; nivel 3: café y té sin azúcar; nivel 4: bebidas no calóricas con edulcorantes artificiales; nivel 5: bebidas con alto valor calórico y beneficios a la salud limitados (jugos de fruta, leche entera, licuados de fruta con azúcar o miel, bebidas alcohólicas y bebidas deportivas); y nivel 6: bebidas con azúcar y bajo contenido de nutrimentos (refrescos y otras bebidas con altas cantidades de azúcares agregadas como jugos, aguas frescas, café y té). El Comité recomienda el consumo de agua en primer lugar, seguido de bebidas sin o con bajo aporte energético y leche descremada. Éstas deben tener prioridad sobre las de mayor aporte energético o endulzadas, incluso con edulcorantes artificiales. Se presentan cantidades recomendadas para cada categoría de bebidas y se ilustran patrones de consumo saludable para adultos de ambos sexos.

Soy protein reduces hepatic lipotoxicity in hyperinsulinemic obese Zucker fa/fa rats.

Hepatic steatosis is commonly present during the development of insulin resistance, and it is a clear sign of lipotoxicity attributable in part to an accelerated lipogenesis. There is evidence that a soy protein diet prevents the overexpression of hepatic sterol-regulatory element binding protein-1 (SREBP-1), decreasing lipid accumulation. Therefore, the aim of the present work was to study whether a soy protein diet may prevent the development of fatty liver through the regulation of transcription factors involved in lipid metabolism in hyperinsulinemic and hyperleptinemic Zucker obese fa/fa rats. Serum and hepatic cholesterol and triglyceride levels, as well as VLDL-triglyceride and LDL-cholesterol, were significantly lower in rats fed soy protein than in rats fed a casein diet for 160 days. The reduction in hepatic cholesterol was associated with a low expression of liver X receptor-alpha and its target genes, 7-alpha hydroxylase and ABCA1. Soy protein also decreased the expression of SREBP-1 and several of its target genes, FAS, stearoyl-CoA desaturase-1, and delta5 and delta6 desaturases, decreasing lipogenesis even in the presence of hyperinsulinemia. Reduction in SREBP-1 was not associated with the presence of soy isoflavones. Finally, soy protein reduced SREBP-1 expression in adipocytes, preventing hypertrophy, which also helps prevent the development of hepatic lipotoxicity.
