Insights into the Role of Bioactive Food Ingredients and the Microbiome in Idiopathic Pulmonary Fibrosis.

Idiopathic pulmonary fibrosis (IPF) is a chronic disease mainly associated with aging and, to date, its causes are still largely unknown. It has been shown that dietary habits can accelerate or delay the occurrence of aging-related diseases; however, their potential role in IPF development has been underestimated so far. The present review summarizes the evidence regarding the relationship between diet and IPF in humans, and in animal models of pulmonary fibrosis, in which we discuss the bioactivity of specific dietary food ingredients, including fatty acids, peptides, amino acids, carbohydrates, vitamins, minerals and phytochemicals. Interestingly, many animal studies reveal preventive and therapeutic effects of particular compounds. Furthermore, it has been recently suggested that the lung and gut microbiota could be involved in IPF, a relationship which may be linked to changes in immunological and inflammatory factors. Thus, all the evidence so far puts forward the idea that the gut-lung axis could be modulated by dietary factors, which in turn have an influence on IPF development. Overall, the data reviewed here support the notion of identifying food ingredients with potential benefits in IPF, with the ultimate aim of designing nutritional approaches as an adjuvant therapeutic strategy.

Systemic contact dermatitis: sometimes it is the food.

Systemic contact dermatitis (SCD) represents a unique pattern of allergic contact dermatitis that may cause a symmetric eruption involving intertriginous skin, genitals, eyelids, and/or hands. Common culprits known to elicit SCD for some patients include preservatives, metals, and fragrances. Certain medications including steroids and antihistamines can cause SCD. For patients who do not improve with skin allergen avoidance alone and who have a pattern of dermatitis suggestive of SCD, counseling on allergen avoidance through oral, parenteral, and inhaled routes is indicated.

Antinutritional factors and hypocholesterolemic effect of wild apricot kernel (Prunus armeniaca L.) as affected by detoxification.

The present investigation was aimed to study the effect of detoxification on the nutrients and antinutrients of wild apricot kernel followed by its hypocholesterolemic effect in male Wistar albino rats. The results revealed a non-significant (p > 0.05) effect of detoxification on the proximate composition except total carbohydrates and protein content. However, detoxification led to a significant (p < 0.05) decrease in l-ascorbic acid (76.82%), ß-carotene (25.90%), dietary fiber constituents (10.51-28.92%), minerals (4.76-31.08%) and antinutritional factors (23.92-77.05%) (phenolics, tannins, trypsin inhibitor activity, saponins, phytic acid, alkaloids, flavonoids, oxalates) along with the complete removal (100%) of bitter and potentially toxic hydrocyanic acid (HCN). The quality parameters of kernel oil indicated no adverse effects of detoxification on free fatty acids, lipase activity, acid value and peroxide value, which remained well below the maximum permissible limit. Blood lipid profile demonstrated that the detoxified apricot kernel group exhibited significantly (p < 0.05) increased levels of HDL-cholesterol (48.79%) and triglycerides (15.09%), and decreased levels of total blood cholesterol (6.99%), LDL-C (22.95%) and VLDL-C (7.90%) compared to that of the raw (untreated) kernel group. Overall, it can be concluded that wild apricot kernel flour could be detoxified efficiently by employing a simple, safe, domestic and cost-effective method, which further has the potential for formulating protein supplements and value-added food products.

An Overview of Novel Dietary Supplements and Food Ingredients in Patients with Metabolic Syndrome and Non-Alcoholic Fatty Liver Disease.

Metabolic syndrome (MetS) is characterized by interconnected factors related to metabolic disturbances, and is directly related to the occurrence of some diseases such as cardiovascular diseases and type 2 diabetes. MetS is described as one or both of insulin resistance and visceral adiposity, considered the initial causes of abnormalities that include hyperglycemia, elevated blood pressure, dyslipidemia, elevated inflammatory markers, and prothrombotic state, as well as polycystic ovarian syndrome in women. Other than in MetS, visceral adiposity and the pro-inflammatory state are also key in the development of non-alcoholic fatty liver disease (NAFLD), which is the most prevalent chronic liver disease in modern society. Both MetS and NAFLD are related to diet and lifestyle, and their treatment may be influenced by dietary pattern changes and the use of certain dietary supplements. This study aimed to review the role of food ingredients and supplements in the management of MetS and NAFLD specifically in human clinical trials. Moreover, bioactive compounds and polyunsaturated fatty acids (PUFAs) may be used as strategies for preventing the onset of and treatment of metabolic disorders, such as MetS and NAFLD, improving the inflammatory state and other comorbidities, such as obesity, dyslipidemias, and cardiovascular diseases (CVD).

Childhood and Adolescent Cancer in the State of Pernambuco, Brazil: Incidence, Geographical Distribution, and Association With Environmental Health Indicators.

Cases of childhood and adolescent cancer diagnosed from 2009 to 2012 in the state of Pernambuco, Brazil, were analyzed considering the patients' sex and age, the type of cancer and the municipality of living to determine the incidence, geographical distribution, and association with environmental health indicators. The spatial distribution pattern of the cancer incidence was estimated using the Global Moran's index. The association between environmental health indicators and cancer incidence was evaluated by multiple regression. From 2009 to 2012, 1261 new cases of cancer were diagnosed in patients younger than 20 years old in the state of Pernambuco. Leukemia/lymphoma were the most common type of cancer contemplating 45.28% of the cases. The average age-adjusted incidence rate was 113 cases per million with no spatial distribution pattern. The municipalities were clustered according to their degree of inequality (P=0.017), human development index (P=0.001), population growth rate (P=0.008), urbanization level (P=0.001), number of agricultural crops per capita (P=0.001), and number of industries per capita (P=0.030). However, only urbanization level was positive correlated with incidence of pediatric cancer (P=0.009) likely because in more developed cities, people are more exposed to potential oncogenic factors, such as air and water pollution and processed and ultraprocessed food. The better access to specialized health services, which increases the chances of early diagnosis, may also contributes for a higher number of cases in more developed cities.

Safety assessment of powdered Cistanche deserticola Y. C. Ma by a 90-day feeding test in Sprague-Dawley rats.

Cistanche deserticola (C. deserticola), a holoparasitic plant widely distributed in arid or semi-arid areas in Eurasia and North Africa, has been used as an important tonic in traditional Eastern medicine for centuries. However, little information on the systemic toxicity and safety evaluation of it is available. The purpose of this study was to investigate the potential toxicity of powdered C. deserticola as a novel food ingredient by use of a subchronic toxicity study in Sprague-Dawley (SD) rats. A total of 80 male and female rats were fed with diets containing 8, 4, 2 and 0% (control) powdered C. deserticola for 90 days. A toxicological assessment was performed including mortality, body and organ weight, food consumption, blood biochemistry, hematology, gross necropsy and histopathological examinations. There were no signs of toxicity and treatment-related changes in rats treated with powdered C. deserticola. The no-observed-adverse-effect level (NOAEL) of powdered C. deserticola was 7.8 g kg-1 body weight for males and 8.0 g kg-1 body weight for females of rats under the experimental conditions of this study.
