Novel digital-based approach for evaluating wine components' intake: A deep learning model to determine red wine volume in a glass from single-view images.

Estimation of wine components' intake (polyphenols, alcohol, etc.) through Food Frequency Questionnaires (FFQs) may be particularly inaccurate. This paper reports the development of a deep learning (DL) method to determine red wine volume from single-view images, along with its application in a consumer study developed via a web service.

Composition of the microbiota in patients with growth hormone deficiency before and after treatment with growth hormone.

Introduction: Growth hormone (GH) and insulin-like growth factor-1 (IGF-1) have modulatory effects on bowel function and its microbiota. Our aim was to investigate whether low levels of GH and IGF-1 in patients with GH deficiency are associated with changes in gut physiology/integrity as well as in the composition of the gut microbiota.

Materials And Methods: We conducted a case-control study in 21 patients with GH deficiency, at baseline and after 6 months of GH treatment, and in 20 healthy controls.

Beyond the effects of HIV infection and integrase inhibitors-based therapies on oral bacteriome.

Oral microbiome is the second largest microbial community in humans after gut. Human immunodeficiency virus (HIV) infection triggers an impairment of the immune system which could favour the growth and the colonization of pathogens in the oral cavity, and this dysbiosis has been associated with oral manifestations that worsen the quality of life of these patients. Antiretroviral therapy (ART) could also drive changes in specific oral bacterial taxa associated with such periodontal diseases.

IGF1R is a mediator of sex-specific metabolism in mice: Effects of age and high-fat diet.

Objective: We aimed to investigate the short and long-term metabolic consequences of IGF1R systemic gene deficiency in mice.

Methods: mutant mice were used to suppress IGF1R signaling in adult tissues by inducing postnatal generalized deletion with tamoxifen. Animals were analyzed at two different ages: ) 13-weeks old young mice, and ) 12-months old middle-aged mice.

Integrase Inhibitors Partially Restore Bacterial Translocation, Inflammation and Gut Permeability Induced by HIV Infection: Impact on Gut Microbiota.

Introduction: Human immunodeficiency virus (HIV) infection can be considered a chronic disease thanks to the extended use of antiretroviral treatment (ART). In this context, low-grade chronic inflammation related to gut microbiota (GM) dysbiosis and bacterial translocation (BT) among other factors has been observed despite the use of ART. In addition, different ART regimens have demonstrated differential impacts on GM.

Corrigendum: ACE Gene Variants Rise the Risk of Severe COVID-19 in Patients With Hypertension, Dyslipidemia or Diabetes: A Spanish Pilot Study.

ACE Gene Variants Rise the Risk of Severe COVID-19 in Patients With Hypertension, Dyslipidemia or Diabetes: A Spanish Pilot Study.

Coronavirus disease 19 (COVID-19) caused by the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection continues to scale and threaten human health and public safety. It is essential to identify those risk factors that lead to a poor prognosis of the disease. A predisposing host genetic background could be one of these factors that explain the interindividual variability to COVID-19 severity.

Autologous fecal transplantation from a lean state potentiates caloric restriction effects on body weight and adiposity in obese mice.

Autologous fecal transplantation (FT-A) emerges as a promising strategy to modulate gut microbiota with minimal side effects since individual´s own feces are transplanted. With the premise of improving obesity and its associated disorders, we investigated if fecal microbiota transplantation (FMT), heterologous and autologous, potentiates the effects of a moderate caloric restriction (CR) in high-fat diet (HFD)-induced obese mice. Mice were randomized into control, HFD, CR (12 weeks on HFD and 6 weeks under CR), FT-H (similar to CR and FMT carried out with feces from controls, weeks 17 & 18), and FT-A (administration of their own feces before developing obesity at weeks 17 & 18).

Short-term effects of direct-acting antiviral agents on inflammation and gut microbiota in hepatitis C-infected patients.

Liver damage is associated with gut dysbiosis. New direct-acting antiviral agents (DAAs) are able to eradicate hepatitis C virus (HCV) from the body. However, the short and medium-term effects of DAAs at gut level before advanced liver damage occurs have not been evaluated yet.

Characterization of gut microbiota composition in HIV-infected patients with metabolic syndrome.

The presence of metabolic syndrome (MS) per se or its separated components in HIV-infected patients contributes to an accelerated aging and increased cardiovascular risk. Gut microbiota (GM) dysbiosis has been linked with chronic inflammation associated with MS in a general non-infected population. However, no studies concerning GM have been performed in HIV-infected patients with MS.

Agaricus bisporus supplementation reduces high-fat diet-induced body weight gain and fatty liver development.

Obesity is a global epidemic characterized not only by excessive fat deposition but also by important complications such as nonalcoholic liver steatosis. Beneficial antiobesogenic effects have been described for some mushrooms. The current study aimed to demonstrate the protective effect of Agaricus bisporus (AB) supplementation against the metabolic alterations induced by high-fat-diet (HFD) feeding.

Differential effects of antiretrovirals on microbial translocation and gut microbiota composition of HIV-infected patients.

Introduction: Increased bacterial translocation and alterations to gut microbiota composition have been described in HIV infection and contribute to immune activation and inflammation. These effects persist despite combined antiretroviral therapy (cART). However, the contribution of different cART combinations has not yet been investigated.

Deciphering the molecular mechanisms involved in HIV-associated lipoatrophy by transcriptomics: a pilot study.

HIV-associated lipoatrophy (LA) has considerable implications for risk of metabolic diseases, quality of life, and adherence to treatments. Although it has decreased in high-income countries, it is still very common in resource-limited countries. Understanding the pathophysiological mechanisms of LA can open the possibility to explore new ways to treat or prevent this condition.

Lack of Adrenomedullin Results in Microbiota Changes and Aggravates Azoxymethane and Dextran Sulfate Sodium-Induced Colitis in Mice.

The link between intestinal inflammation, microbiota, and colorectal cancer is intriguing and the potential underlying mechanisms remain unknown. Here we evaluate the influence of adrenomedullin (AM) in microbiota composition and its impact on colitis with an inducible knockout (KO) mouse model for AM. Microbiota composition was analyzed in KO and wild type (WT) mice by massive sequencing.

Maraviroc ameliorates the increased adipose tissue macrophage recruitment induced by a high-fat diet in a mouse model of obesity.

Background: Any strategy designed to decrease the macrophage content in adipose tissue (AT) is of great value as a way to decrease inflammation in this fat depot and also as a way to prevent or treat obesity and associated disorders. Maraviroc (MVC), a CCR5 antagonist approved for the treatment of HIV-infected patients, has beneficial effects on metabolism. The objective of this study was to investigate the effects of MVC on AT macrophage recruitment in a mouse model of obesity.
