South African consumers’ knowledge, opinions and awareness of whole grains and their health benefits : a cross-sectional online survey
DATA AVAILABILITY STATEMENT : The de-identified data is available on request.SUPPLEMENTARY MATERIALS : S1 Whole grains survey questions.Evidence indicates that whole-grain food consumption reduces the risk of cardiovascular
disease, type-2 diabetes, and some cancers. Increasing whole-grain consumption in developing
countries is likely to significantly benefit the health of the population. However, there is very limited
information on consumer whole-grain knowledge, attitudes, and behaviors in developing countries.
An online cross-sectional survey was conducted among 1000 South African consumers with sufficient
income to make food purchase choices and who were generally representative in terms of gender,
age, and ethnicity. Most respondents (64%) were confident of their whole-grain knowledge. However,
60% of all participants selected incorrect definitions of whole grains. Whilst most correctly identified
common cereals as whole grains, at most 50% of participants correctly identified common whole-grain
foods. Also, whilst most (67%) thought that they were consuming enough whole grains, the majority
(62%) underestimated the recommended level of consumption. Furthermore, respondent knowledge
regarding whole-grain food attributes and the health benefits of whole-grain consumption was
generally poor. Clearly, consumer-focused strategies are needed in developing countries to increase
whole-grain food consumption to help the broader population achieve a healthy and sustainable
diet. Actions proposed include: simple-to-understand information on whole-grain content relative
to recommendations on food product labels, the provision of whole-grain foods in school nutrition
schemes, and coordinated social and behavior change communication initiatives.Pepsico SSA.https://www.mdpi.com/journal/nutrientsam2024Consumer ScienceSDG-02:Zero HungerSDG-03:Good heatlh and well-bein
Comparative Study of the Sensitivity of Different Diagnostic Methods for the Laboratory Diagnosis of Buruli Ulcer Disease
Background. Several diagnostic laboratory methods are available for case confirmation of Buruli ulcer disease. This study assessed the sensitivity of various diagnostic tests in relation to clinical presentation of the disease, type of diagnostic specimen, and treatment history. Methods. Swab samples, 3-mm punch biopsy tissue specimens, and surgically excised tissue specimens from 384 individuals with suspected Buruli ulcer disease were obtained at 9 different study sites in Ghana and were evaluated with dry reagent-based polymerase chain reaction (PCR), microscopic examination, culture, and histopathological analysis. The study subjects presented with nonulcerative and ulcerative lesions and were divided into 3 treatment groups: (1) previously untreated patients scheduled for antimycobacterial treatment, (2) patients treated with surgery alone, and (3) patients treated with surgery in combination with previous antimycobacterial treatment. Results. Of 384 suspected cases of Buruli ulcer disease, 268 were confirmed by at least 1 positive test result. The overall sensitivity of PCR (85%) was significantly higher than that of microscopic examination (57%) and culture (51%). After data were stratified by treatment group, type of lesion, and diagnostic specimen type, analysis revealed that PCR of 3-mm punch biopsy tissue specimens (obtained from previously untreated nonulcerative lesions) and of swab samples (obtained from previously untreated ulcers) had the highest diagnostic sensitivity (94% and 90%, respectively). Although duration of the disease did not significantly influence the sensitivity of any test, previous antimycobacterial treatment was significantly associated with decreased sensitivity of PCR and culture. Conclusions. Across all subgroups, PCR had the highest sensitivity. PCR assessment of 3-mm punch biopsy tissue specimens proved to be the best diagnostic tool for nonulcerative lesions, and PCR assessment of swab samples was the best diagnostic tool for ulcerative lesions. For monitoring of antimycobacterial treatment success within controlled trials, however, only culture is appropriat
An eIF3d-dependent switch regulates HCMV replication by remodeling the infected cell translation landscape to mimic chronic ER stress
Regulated loading of eIF3-bound 40S ribosomes on capped mRNA is generally dependent upon the translation initiation factor eIF4E; however, mRNA translation often proceeds during physiological stress, such as virus infection, when eIF4E availability and activity are limiting. It remains poorly understood how translation of virus and host mRNAs are regulated during infection stress. While initially sensitive to mTOR inhibition, which limits eIF4E-dependent translation, we show that protein synthesis in human cytomegalovirus (HCMV)-infected cells unexpectedly becomes progressively reliant upon eIF3d. Targeting eIF3d selectively inhibits HCMV replication, reduces polyribosome abundance, and interferes with expression of essential virus genes and a host gene expression signature indicative of chronic ER stress that fosters HCMV reproduction. This reveals a strategy whereby cellular eIF3d-dependent protein production is hijacked to exploit virus-induced ER stress. Moreover, it establishes how switching between eIF4E and eIF3d-responsive cap-dependent translation can differentially tune virus and host gene expression in infected cells
Garnering Partnerships to Bridge Gaps Among Mental Health, Health Care, and Public Health
Integrating mental health and public health chronic disease programs requires partnerships at all government levels. Four examples illustrate this approach: 1) a federal partnership to implement mental health and mental illness modules in the Behavioral Risk Factor Surveillance System; 2) a state partnership to improve diabetes health outcomes for people with mental illness; 3) a community-level example of a partnership with local aging and disability agencies to modify a home health service to reduce depression and improve quality of life among isolated, chronically ill seniors; and 4) a second community-level example of a partnership to promote depression screening and management and secure coverage in primary care settings. Integration of mental health and chronic disease public health programs is a challenging but essential and achievable task in protecting Americans’ health
Targeting the m(6)A RNA modification pathway blocks SARS-CoV-2 and HCoV-OC43 replication
N-6-methyladenosine (m(6)A) is an abundant internal RNA modification, influencing transcript fate and function in uninfected and virus-infected cells. Installation of m(6)A by the nuclear RNA methyltransferase METTL3 occurs cotranscriptionally; however, the genomes of some cytoplasmic RNA viruses are also m(6)A-modified. How the cellular m(6)A modification machinery impacts coronavirus replication, which occurs exclusively in the cytoplasm, is unknown. Here we show that replication of SARS-CoV-2, the agent responsible for the COVID-19 pandemic, and a seasonal human beta-coronavirus HCoV-OC43, can be suppressed by depletion of METTL3 or cytoplasmic m(6)A reader proteins YTHDF1 and YTHDF3 and by a highly specific small molecule METTL3 inhibitor. Reduction of infectious titer correlates with decreased synthesis of viral RNAs and the essential nucleocapsid (N) protein. Sites of m(6)A modification on genomic and subgenomic RNAs of both viruses were mapped by methylated RNA immunoprecipitation sequencing (meRIP-seq). Levels of host factors involved in m(6)A installation, removal, and recognition were unchanged by HCoV-OC43 infection; however, nuclear localization of METTL3 and cytoplasmic m(6)A readers YTHDF1 and YTHDF2 increased. This establishes that coronavirus RNAs are m(6)A-modified and host m(6)A pathway components control beta-coronavirus replication. Moreover, it illustrates the therapeutic potential of targeting the m(6)A pathway to restrict coronavirus reproduction
