Spotlight on the Compositional Quality of Probiotic Formulations Marketed Worldwide

On the worldwide market, a great number of probiotic formulations are available to consumers as drugs, dietary supplements, and functional foods. For exerting their beneficial effects on host health, these preparations should contain a sufficient amount of the indicated living microbes and be pathogen-free to be safe. Therefore, the contained microbial species and their amount until product expiry are required to be accurately reported on the labels. While commercial formulations licensed as drugs are subjected to rigorous quality controls, less stringent regulations are generally applied to preparations categorized as dietary supplements and functional foods. Many reports indicated that the content of several probiotic formulations does not always correspond to the label claims in terms of microbial identification, number of living organisms, and purity, highlighting the requirement for more stringent quality controls by manufacturers. The main focus of this review is to provide an in-depth overview of the microbiological quality of probiotic formulations commercialized worldwide. Many incongruences in the compositional quality of some probiotic formulations available on the worldwide market were highlighted. Even if manufacturers carry at least some of the responsibility for these inconsistencies, studies that analyze probiotic products should be conducted following recommended and up-to-date methodologies.

Employing Position Generators to Assess Social Capital and Health: A Scoping Review of the Literature and Recommendations in Future Population Health Surveillance

Beneficial social connections are critical to individual-level health. These connections increase access to social support/resources that can be used to avoid or minimize the risks and consequences associated with diseases. How to best measure beneficial social connections to inform social network-level health interventions remains poorly understood. A scoping review of empirical health research studies was conducted to highlight the utility of employing position generators to assess how access to beneficial social connections was associated with population health and disparities. Our review yielded 39 articles of studies conducted between 2006-2018 across 14 predominantly high-income countries. Most studies (77%) with composite measures for beneficial social connections exhibited health-protective associations. Of the remaining articles, half found that greater diversity within one's network was associated with positive health outcomes. Only eight articles accounted for differences by advantaged statuses, indicating that beneficial connections elicited greater health-protective associations among disadvantaged groups. Employing position generators may inform interventions that seek to reduce health disparities by enhancing social capital in individuals from disadvantaged backgrounds.

The impact of handwriting difficulties on compositional quality in children with developmental coordination disorder

Introduction

There is substantial evidence to support the relationship between transcription skills (handwriting and spelling) and compositional quality. For children with developmental coordination disorder, handwriting can be particularly challenging. While recent research has aimed to investigate their handwriting difficulties in more detail, the impact of transcription on their compositional quality has not previously been examined. The aim of this exploratory study was to examine compositional quality in children with developmental coordination disorder and to ascertain whether their transcription skills influence writing quality.

Method

Twenty-eight children with developmental coordination disorder participated in the study, with 28 typically developing age and gender matched controls. The children completed the ‘free-writing’ task from the detailed assessment of speed of handwriting tool, which was evaluated for compositional quality using the Wechsler objective language dimensions.

Results

The children with developmental coordination disorder performed significantly below their typically developing peers on five of the six Wechsler objective language dimensions items. They also had a higher percentage of misspelled words. Regression analyses indicated that the number of words produced per minute and the percentage of misspelled words explained 55% of the variance for compositional quality.

Conclusion

The handwriting difficulties so commonly reported in children with developmental coordination disorder have wider repercussions for the quality of written composition.
