S. aureus and IgE-mediated diseases: pilot or copilot? A narrative review.

Introduction: is a major opportunistic pathogen that has been implicated in the pathogenesis of several chronic inflammatory diseases including bronchial asthma, chronic rhinosinusitis with nasal polyps (CRSwNP), chronic spontaneous urticaria (CSU), and atopic dermatitis. can induce the production of both polyclonal and specific IgE that can elicit an inflammatory cascade.

Areas Covered: The link between the sensitization to enterotoxins and the severity of several chronic inflammatory diseases is reviewed in detail, as well as its therapeutic implications.

Indacaterol/glycopyrronium/mometasone fixed dose combination for uncontrolled asthma.

Introduction: Asthma symptoms can be relieved through a maintenance treatment combining long-acting β-agonist and inhaled corticosteroids (LABA/ICS). However, for patients with inadequately controlled asthma, the LABA/ICS combination might not be sufficient, and clinical guidelines recommend the administration of inhaled long-acting muscarinic antagonists (LAMA) as an add-on therapy to better control asthma and improve lung function. For nearly two decades, the only LAMA to be approved on the market has been tiotropium.

Not one, but many "publics": public engagement with global development in France, Germany, Great Britain, and the United States.

Using new panel data from the Aid Attitudes Tracker (2013-18), this article draws on a set of 18 actions to map public engagement with global poverty in France, Germany, Great Britain and the United States. It introduces a new engagement segmentation comprised of five distinct groups - the totally disengaged, marginally engaged, informationally engaged, behaviourally engaged, and fully engaged. The data provide evidence of both aggregate and individual-level change in engagement over time but with an important distinction: respondents in less engaged groups are less likely to move out of these groups and tend to stay unengaged.

Self-administration of omalizumab: why not? A literature review and expert opinion.

: Omalizumab is used to treat severe uncontrolled allergic asthma and chronic spontaneous urticaria (CSU), and is approved for self-administration in prefilled syringes. It is thus important to understand the advantages, critical issues, and indications for home administration.: The present review summarizes the available evidence on home administration of omalizumab in asthma and CSU to illustrate the advantages derived from self-administration of patients in this setting.

New equations to estimate resting energy expenditure in obese adults from body composition.

Aims: The aims of this study were: to develop new equations for predicting resting energy expenditure (REE) in obese Italian subjects according to body composition parameters; to compare them with predicted values estimated by other REE prediction equations; and to cross-validate our equations using a validation set cohort.

Methods: Four hundred patients were enrolled and divided into three groups. Besides anthropometry and REE (indirect calorimetry), total body fat and lean were evaluated by dual X-ray absorptiometry, and fat mass and fat-free mass by bioelectrical impedance analysis.

Direct spectroscopic (FTIR) detection of intraspecific binary contaminations in yeast cultures.

Fourier transform infrared spectroscopy has proved to be a good method to identify and characterize microorganisms. This technique has been proposed as a tool to determine the level of contamination in binary mixtures of strains belonging to different species and even to diverse kingdoms, showing a good linear relationship between spectral outputs and contamination levels. The monitoring of intraspecific contamination is a critical point in both laboratory practice and industrial monitoring, but it is challenged by the difficulty to discriminate between very similar cultures belonging to the same species.

Feasibility of air plethysmography (BOD POD) in morbid obesity: a pilot study.

The assessment of body composition (BC) in morbidly obese patients is a difficult procedure. Air-displacement plethysmography (ADP), which measures body density, is a very promising technique for BC assessment in health and disease. However, there are very few data about the feasibility of applying ADP on morbidly obese patients, which theoretically could be affected by large body size and difficulty in lung volume measurements.

Assessment by bioimpedance of forearm cell mass: a new approach to calibration.

Objective: Changes in skeletal muscle mass are involved in several important clinical disorders including sarcopenia and obesity. Unlike body fat, skeletal muscle is difficult to quantify in vivo, particularly without highly specialized equipment. The present study had a two-fold aim: to develop a regional (40)K counter for non-invasively estimating cell mass in the arm, mainly skeletal muscle cell mass, without radiation exposure; and to test the hypothesis that cell mass in the arm is highly correlated with electrical impedance after adjusting for the arm's length.

Use of quality control indices in moderately hypocaloric Mediterranean diet for treatment of obesity.

A large number of studies have been published on very-low calorie diets and markedly hypocaloric dietary regimens for treatment of obesity. However, scanty data are available on moderately hypocaloric diets based on the Mediterranean diet model. We evaluated the efficacy and safety of a moderately hypocaloric Mediterranean diet (MHMD) by assessing changes in body composition and in metabolic profile in 19 obese women, aged 32+/-4 years, body weight 84.

Is body mass index a measure of adiposity in elderly women?

Objective: To evaluate the accuracy of body mass index (BMI) as a predictor of body fat in elderly women.

Research Methods And Procedures: A total of 1423 women aged 67 +/- 5 (mean +/- SD, range: 60 to 88) years were consecutively enrolled into the study. Fat mass (FM) was measured using DXA.

Changes of bioelectrical impedance after a body weight reduction program in highly obese subjects.

We used bioelectrical impedance analysis (BIA) as an exploratory tool to monitor the changes in body composition induced by a short-term (3-wk) weight reduction (energy-restricted diet, moderate aerobic exercise conditioning and psychological counselling) in 175 highly obese subjects (body mass index, BMI=41.7+/-5.8 kg/m2).

[Craniosynostosis: is prenatal diagnosis possible?].

The authors report a case which demonstrates how an interdisciplinary collaboration between the obstetrician and pediatrician may be activated in the event of a suspected fetal malformation, in this case craniosynostosis, although it is important to recognise the diagnostic limitations of ultrasonography regarding this type of pathology.

Appendicular skeletal muscle mass: prediction from multiple frequency segmental bioimpedance analysis.

Objectives: Bioimpedance analysis (BIA) methods have potential to predict appendicular skeletal muscle mass (SM), although available 50 kHz prediction models include, in addition to impedance (Z), an independent age term. An age term in models is undesirable as it reflects incomplete understanding of underlying conduction physiology. This study tested the hypothesis, based on fluid distribution models related to aging, that appendicular SM bioimpedance analysis (BIA) prediction models would no longer include an independent age term, after first controlling for stature-adjusted appendicular impedance (height2/Z), at injected frequencies greater than 50 kHz.

Anthropometric characteristics of healthy Italian nonagenarians and centenarians.

Available anthropometric reference values for elderly people do not include specific norms for over-90-year-old subjects despite their increasing number. In the present study, weight, height and a number of anthropometric variables related to body muscle and fat mass were collected from fifty-seven nonagenarian and forty-one centenarian healthy, non-institutionalized subjects living in an Italian area. Recumbent anthropometry was used to avoid errors associated with impaired mobility.

Coenzyme Q10 plasma levels and body composition in elderly males.

Male aging is associated with alterations in plasma levels of antioxidants such as Coenzyme Q(10) (CoQ(10)) , and with a decrease of the fat-free body mass (FFM). In order to reveal, whether these changes can affect CoQ(10) metabolism, 73 non-obese, healthy males were studied, in age range 22-100 years, divided in 4 age groups: 20-55 (n = 23); 56-70 (n = 20); 71-90 (n = 8) and 91-100 (n =22). Serum CoQ(10) was measured by HPLC technique.

Microvascular capillaroscopic abnormalities in rheumatoid arthritis patients.

Microvascular circulation was investigated by nailfold capillaroscopy in 32 patients affected by rheumatoid arthritis (RA). In all the patients elongated and tiny capillaries as well as tortuousity were the main shape abnormalities of the capillary loops. Higher subpapilar venous plexus (SPVP) visibility was evidentiated in patients presenting antinuclear and anti-RANA antibodies.

The prediction of total body water from body impedance in young obese subjects.

Almost all formulae for the prediction of total body water (TBW) from body impedance are based on the assumption of a constant conductor configuration--i.e. a constant subject section.

Differential action of thyroid hormones on the activity of certain enzymes in rat kidney and brain.

In rat kidney several mitochondrial and soluble enzyme activities are stimulated by thyroid hormones and the mitochondrial membrane fluidity is also increased. However, the ketone metabolism enzyme activities of D-3-hydroxybutyrate dehydrogenase and of 3-oxoacid CoA-transferase are not significantly affected by the hyperthyroid state and the ketone body concentration is not greatly changed. Therefore, in hyperthyroid rats the response of the kidney, as far as the ketone bodies and their metabolizing enzymes are concerned, is at variance with that of the liver and the heart.

The response of rat liver lipid peroxidation, antioxidant enzyme activities and glutathione concentration to the thyroid hormone.

1. In liver microsomes from hyperthyroid rats NADPH-dependent lipid peroxidation induces a hydroperoxide formation 56% higher than that in euthyroid ones. 2.

Lipid peroxidation in rat liver microsomes. II. Response of hydroperoxide formation to iron concentration.

When rat liver microsomes were incubated with NADPH, the major products were hydroperoxides which increased with time indicating that endogenous iron content is able to promote lipid peroxidation. The addition of either 5 microM Fe2+ or Fe3+ ions strongly enhanced the hydroperoxide formation rate. However, due to the hydroperoxide breakdown, hydroperoxide concentration decreased with time in this case.

Concerning the decreased D-3-hydroxybutyrate dehydrogenase activity in the liver and heart of hyperthyroid rats.

Whereas in rat liver mitochondria the hyperthyroid state causes an increase both in fatty acid unsaturation and in the Ea of D-3-hydroxybutyrate dehydrogenase and a decrease in phase transition temperature, in hyperthyroid rat heart mitochondria these changes are negligible. D-3-hydroxybutyrate dehydrogenase in both the liver and the heart mitochondria of hyperthyroid rats is reduced by about 35% [12] but this reduction is not due to changes in membrane fluidity in either tissue. Hypothyroidism, on the other hand, affects BDH activity in neither heart nor liver.

Lipid peroxidation in rat liver microsomes. I. Stimulation of the NADPH-cytochrome P-450 reductase-dependent process in hyperthyroid state.

The effect of hyper- and hypothyroidism on lipid peroxidation has been studied in rat liver microsomes under three different experimental conditions. Under none of these conditions was the formation of TBA-reactive substances affected by either of these two pathological states. On the contrary, with NADPH as the only peroxidation inducer, hydroperoxide concentration increased some three fold in microsomes from hyperthyroid rats, while a small decrease was measured in those from hypothyroid animals.

[Comparison between serum ferritin and induced sideruria in the diagnosis of disorders of iron metabolism].

The A. compare the values of serum ferritin and Desferrioxamine (DFO)-induced sideruria on 73 patients affected by different diseases. The results may be divided into three groups: a first one concerning patients with low serum ferritin and low DFO-induced sideruria, a second one of patients with normal serum ferritin and normal DFO-induced sideruria; in the third group of patients the A.
