Multicriteria Measures to Assess the Sustainability of Diets: A Systematic Review.

CONTEXT: Assessing the overall sustainability of a diet is a challenging undertaking requiring a holistic approach capable of addressing the multicriteria nature of this concept. OBJECTIVE: The aim was to identify and summarize the multicriteria measures used to assess the sustainability characteristics of diets reported at the individual level by healthy adults. DATA SOURCES: Articles were identified via PubMed, Scopus, and Web of Science. The search strategy consisted of key words and MeSH terms, and was concluded in September 2022, covering references in English, Spanish, and Portuguese. DATA EXTRACTION: This systematic review followed the PRISMA guidelines. The search identified 5663 references, from which 1794 were duplicates. Two reviewers independently screened the titles and abstracts of each of the 3869 records and the full-text of the 144 references selected. Of these, 7 studies met the inclusion criteria. DATA ANALYSIS: A total of 6 multicriteria measures were identified: 3 different Sustainable Diet Indices, the Quality Environmental Costs of Diet, the Quality Financial Costs of Diet, and the Environmental Impact of Diet. All of these incorporated a health/nutrition dimension, while the environmental and economic dimensions were the second and the third most integrated, respectively. A sociocultural sustainability dimension was included in only 1 of the measures. CONCLUSION: Despite some methodological concerns in the development and validation process of the identified measures, their inclusion is considered indispensable in assessing the transition towards sustainable diets in future studies.

Barriers and facilitators to implementation of point-of-care lung ultrasonography in a tertiary centre in Benin: a qualitative study among general physicians and pneumologists.

OBJECTIVES: Owing to its ease-of-use and excellent diagnostic performance for the assessment of respiratory symptoms, point-of-care lung ultrasound (POC-LUS) has emerged as an attractive skill in resource-low settings, where limited access to specialist care and inconsistent radiology services erode health equity.To narrow down the research to practice gap, this study aims to gain in-depth insights in the perceptions on POC-LUS and computer-assisted POC-LUS for the diagnosis of lower respiratory tract infections (LRTIs) in a low-income and middle-income country (LMIC) of sub-Saharan Africa. DESIGN AND SETTING: Qualitative study using face-to-face semi-structured interviews with three pneumologists and five general physicians in a tertiary centre for pneumology and tuberculosis in Benin, West Africa. The center hosts a prospective cohort study on the diagnostic performance of POC-LUS for LRTI. In this context, all participants started a POC-LUS training programme 6 months before the current study. Transcripts were coded by the interviewer, checked for intercoder reliability by an independent psychologist, compared and thematically summarised according to grounded theory methods. RESULTS: Various barriers- and facilitators+ to POC-LUS implementation were identified related to four principal categories: (1) hospital setting (eg, lack of resources for device renewal or maintenance-, need for POC tests+), (2) physician's perceptions (eg, lack of opportunity to practice-, willingness to appropriate the technique+), (3) tool characteristics (eg, unclear lifespan-, expedited diagnosis+) and (4) patient's experience (no analogous image to keep-, reduction in costs+). Furthermore, all interviewees had positive attitudes towards computer-assisted POC-LUS. CONCLUSIONS: There is a clear need for POC affordable lung imaging techniques in LMIC and physicians are willing to implement POC-LUS to optimise the diagnostic approach of LRTI with an affordable tool. Successful integration of POC-LUS into clinical routine will require adequate responses to local challenges related to the lack of available maintenance resources and limited opportunity to supervised practice for physicians.

The Influence of Serious Games in the Promotion of Healthy Diet and Physical Activity Health: A Systematic Review.

(1) Background: serious games seem to show promising strategies to promote treatment compliance and motivate behavior changes, and some studies have proven to contribute to the literature on serious games. (2) Methods: this systematic review aimed to analyze the effect of serious games in promoting healthy eating behaviors, effectively preventing childhood obesity, and improving physical activity in children. Five electronic bibliographic databases-PubMed, ACM Digital Library, Games for Health Journal, and IEEE Xplore were used to conduct a systematic literature search based on fixed inclusion and exclusion criteria. Peer-reviewed journal articles published between 2003 and 2021 were selected for data extraction. (3) Results: a total of 26 studies were identified, representing 17 games. Half of the studies tested interventions for healthy eating and physical education. Most of the intervention's games were designed according to specific behavioral change theories, predominantly the social cognitive theory. (4) Conclusions: studies confirmed the potential of serious games for obesity prevention but considering the restrictions encountered, we exhort for novel designs with different theoretical perspectives.

Serine Is an Essential Metabolite for Effector T Cell Expansion.

During immune challenge, T lymphocytes engage pathways of anabolic metabolism to support clonal expansion and the development of effector functions. Here we report a critical role for the non-essential amino acid serine in effector T cell responses. Upon activation, T cells upregulate enzymes of the serine, glycine, one-carbon (SGOC) metabolic network, and rapidly increase processing of serine into one-carbon metabolism. We show that extracellular serine is required for optimal T cell expansion even in glucose concentrations sufficient to support T cell activation, bioenergetics, and effector function. Restricting dietary serine impairs pathogen-driven expansion of T cells in vivo, without affecting overall immune cell homeostasis. Mechanistically, serine supplies glycine and one-carbon units for de novo nucleotide biosynthesis in proliferating T cells, and one-carbon units from formate can rescue T cells from serine deprivation. Our data implicate serine as a key immunometabolite that directly modulates adaptive immunity by controlling T cell proliferative capacity.

Burnout at Work in Modern Times.

The theme of this research is burnout at work in modern times. The main objective is to analyze aspects of mental health worker. The specific objectives are to evaluate the issue of health and mental illness in the workplace, to understand the field of psychodynamics of work, and to analyze the work and the mental strain. The methodology used is the literature review. We conclude that is not the hostile environment that directly causes burnout and other conditions, but the inability to deal with the powerlessness of the working conditions.

Opiate- and cocaine-related fatal overdoses in Luxembourg from 1985 to 2011: a study on gender differences.

BACKGROUND/AIM: We analysed gender differences in national fatal overdose (FOD) cases related to opiates and cocaine use between 1985 and 2011 (n = 340). METHODS: Cross-examination of national data from law enforcement and drug use surveillance sources and of forensic evidence. Bivariate and logistic regression analysis of male/female differences according to sociodemographics, forensic evidence and drug use trajectories. RESULTS: The burden of deaths caused by FOD on the general national mortality was higher for men (PMR/100=0.55) compared with women (PMR/100=0.34). Compared with their male peers, women were younger at the time of death (t=3.274; p=0.001) and showed shorter drug use careers (t=2.228; p=0.028). Heroin use was recorded more frequently in first drug offences of female victims (AOR=6.59; 95% CI 2.97-14.63) and according to forensic evidence, psychotropic prescription drugs were detected to a higher degree in females (AOR=2.019; 95% CI 1.065-3.827). CONCLUSION: The time window between the onset of illicit drug use and its fatal outcome revealed to be shorter for women versus men included in our study. Early intervention in female drug users, routine involvement of first-line healthcare providers and increased attention to use of poly- and psychotropic prescription drugs might contribute to prevent premature drug-related death and reduce gender differences.
