the daily recommended allowance. Changes in dietary fiber intake affect human health not only through the uptake of nutrients directly but also indirectly through changes in the microbial community and their associated metabolism. Here, we conducted a 2-week diet intervention in healthy young adults to investigate the impact of fiber consumption on the gut microbiome. Participants increased their average fiber consumption by 25 g/day on average for 2 weeks. The high-fiber diet intervention altered the gut microbiome of the study participants, including increases in known fiber-degrading microbes, such as Bifidobacterium and Lactobacillus.Glucose-6-phosphate dehydrogenase (G6PDH) is widely distributed in nature and catalyzes the first committing step in the oxidative branch of the pentose phosphate (PP) pathway, feeding either the reductive PP or the Entner-Doudoroff pathway. Besides its role in central carbon metabolism, this dehydrogenase provides reduced cofactors, thereby affecting redox balance. Although G6PDH is typically considered to display specificity toward NADP+, some variants accept NAD+ similarly or even preferentially. Furthermore, the number of G6PDH isozymes encoded in bacterial genomes varies from none to more than four orthologues. On this background, we systematically analyzed the interplay of the three G6PDH isoforms of the soil bacterium Pseudomonas putida KT2440 from genomic, genetic, and biochemical perspectives. P. putida represents an ideal model to tackle this endeavor, as its genome harbors gene orthologues for most dehydrogenases in central carbon metabolism. We show that the three G6PDHs of strain KT2440 have diffely unexplored. We have adopted the metabolically versatile soil bacterium Pseudomonas putida KT2440 as a model to interrogate the physiological and evolutionary significance of coexisting glucose-6-phosphate dehydrogenase (G6PDH) isozymes. Our results show that each of the three G6PDHs in this bacterium display distinct biochemical properties, especially at the level of cofactor preference, impacting bacterial physiology in a carbon source-dependent fashion. Furthermore, the presence of multiple G6PDHs differing in NAD+ or NADP+ specificity in bacterial species strongly correlates with their predominant metabolic lifestyle. Our findings support the notion that multiplication of genes encoding cofactor-dependent dehydrogenases is a general evolutionary strategy toward achieving redox balance according to the growth conditions.
To evaluate the proportion of patients with symptoms suggestive of asthma and normal lung function who exhibit airway hyperreactivity with methacholine challenge testing (MCT) in primary care.

Retrospective chart review.

Primary care lung clinic in Toronto, Ont.

A total of 69 patients presenting to the lung clinic who had symptoms compatible with asthma, normal spirometry test results, and were referred for MCT.

Descriptive statistics, frequency counts, independent
tests, and
tests were used to examine differences in the proportion of clinical and demographic variables identified in patients with or without a positive MCT result. Effect size was determined between MCT-positive and MCT-negative patients for both categorical ( coefficient) and continuous (Hedges
) data.

Twenty-one patients (30.4%) had positive MCT results, and 48 patients (69.6%) had negative MCT results. Family history of asthma and reduced baseline and postbronchodilator forced expiratory volume in 1 second were associated with a positive MCT result.

The findings of this study provide insight into the utility of simple spirometry for asthma diagnosis and the need to further clarify the role of MCT in the primary care setting.

To determine the mean number of chronic diseases in Canadians aged 45 to 85 years who are living in the community, and to characterize the association of multimorbidity with age, sex, and social position.

An analysis of data from the Canadian Longitudinal Study on Aging. The number of self-reported chronic diseases was summed, and then the mean number of chronic health problems was standardized to the 2011 Canadian population. Analyses were conducted stratified on sex, age, individual income, household income, and education level.

Canada.

A total of 21 241 community-living Canadians aged 45 to 85 years.

Overall, 31 chronic diseases (self-reported from a list) were considered, as were risk factors that were not mental health conditions or acute in nature. Age, sex, education, and household and individual incomes were also self-reported.

Multimorbidity was common, and the mean number of chronic illnesses was 3.1. Women had a higher number of chronic illnesses than men. Those with lower income and less education had more chronic conditions. The number of chronic conditions was strongly associated with age. selleck chemicals llc The mean number of conditions was 2.1 in those aged 45 to 54; 2.9 in those 55 to 64; 3.8 in those aged 65 to 74, and 4.8 in those aged 75 and older (
< .05, ANOVA [analysis of variance]).

Multimorbidity is common in the Canadian population and is strongly related to age.

I frequently encounter infants with symptoms suggestive of allergy after being introduced to standard cow's milk formula. Parents are concerned and ask for recommendations regarding formula alternatives. Which formulas are best for children with cow's milk allergy?

Cow's milk allergy is common, and the criterion standard for diagnosis is elimination, provocation (with a double-blind, placebo-controlled food challenge protocol), and re-elimination. The allergy is treated by eliminating cow's milk protein from the diet. Formula alternatives include hydrolyzed cow's milk formula, rice-based formula, soy-based formula, and amino acid-based formula, which are all nutritionally adequate alternatives to cow's milk formula. Symptom severity, patient preference, cost, and efficacy are factors to be considered when choosing an alternative.
