Perinatal malnutrition is a critical cause of diseases in offspring. Based on the different rates of organ development, we hypothesised that malnutrition at varying early life stages would have a differential impact on cardiovascular disease in middle-aged and older adults. This study sought to assess the long-term impact of exposure to the 1959-1961 Great Chinese Famine (GCF) during early developmental periods on risks of cardiovascular diseases in the late middle-aged offspring. A total 6, 662 individuals, born between 1958 and 1964, were divided into six groups according to the birth date. The generalised line model was used to control age and estimate differences with 95% confidence interval (CI) in blood pressure. Binary logistic regression was applied to evaluate the association between famine exposure and cardiovascular diseases. Compared to the unexposed late middle-aged persons, blood pressure was elevated in the entire gestation exposure group, regardless of postnatal exposure to GCF. Increased blood pressure was also found in the female offspring exposed to GCF during early and middle gestation. The early-childhood exposure was associated with the risk of bradycardia in the offspring. The risks of vertebral artery atherosclerosis were elevated in GCF famine-exposed groups except first trimester exposed group. The chronic influence of GCF in early life periods was specific to the developmental timing window, sexesand organs, suggesting an essential role of interactions among multiple factors and prenatal malnutrition in developmentally "programming" cardiovascular diseases.

Plasma levels of branched-chain amino acids (BCAA) and their metabolites, branched-chain ketoacids (BCKA), are increased in insulin resistance. We previously showed that ketoisocaproic acid (KIC) suppressed insulin-stimulated glucose transport in L6 myotubes, especially in myotubes depleted of branched-chain ketoacid dehydrogenase (BCKD), the enzyme that decarboxylates BCKA. This suggests that upregulating BCKD activity might improve insulin sensitivity. We hypothesised that increasing BCAA catabolism would upregulate insulin-stimulated glucose transport and attenuate insulin resistance induced by BCKA. L6 myotubes were either depleted of BCKD kinase (BDK), the enzyme that inhibits BCKD activity, or treated with BT2, a BDK inhibitor. Myotubes were then treated with KIC (200 μM), leucine (150 μM), BCKA (200 μM), or BCAA (400 μM) and then treated with or without insulin (100 nM). BDK depletion/inhibition rescued the suppression of insulin-stimulated glucose transport by KIC/BCKA. This was consistent with the attenuation of IRS-1 (Ser612) and S6K1 (Thr389) phosphorylation but there was no effect on Akt (Ser473) phosphorylation. The effect of leucine or BCAA on these measures was not as pronounced and BT2 did not influence the effect. Induction of the mTORC1/IRS-1 (Ser612) axis abolished the attenuating effect of BT2 treatment on glucose transport in cells treated with KIC. Surprisingly, rapamycin co-treatment with BT2 and KIC further reduced glucose transport. Our data suggests that the suppression of insulin-stimulated glucose transport by KIC/BCKA in muscle is mediated by mTORC1/S6K1 signalling. This was attenuated by upregulating BCAA catabolic flux. Thus, interventions targeting BCAA metabolism may provide benefits against insulin resistance and its sequelae.

Obesity rates in Colombia are increasing, with variations among racial and ethnic groups. Studies on adult obesity often address socio-economic status, gender, and education but neglect racial-ethnic influences, notably in areas like Quibdó. Therefore, based on the theory of triadic influence, we conducted a qualitative study to identify biobehavioural, social, and cultural phenomena that, from the perspectives of the participants, influence the onset of obesity in Afro-Colombian and indigenous in Quibdó in 2022. The stratification variables were race, ethnicity (Afro-Colombian and Indigenous), and educational level (secondary or higher). Based on a literature review of qualitative studies that commonly explored food culture, nutritional status, and physical activity in analysing obesity within racial and ethnic populations, we incorporated these categories into our research methodology through semi-structured interviews. A framework analysis was used as a qualitative methodology to organise and analyse the collected data. We conducted 21 semi-structured interviews, 13 with the Afro-Colombian population and eight with indigenous inhabitants. The results indicate that cultural beliefs, forced displacement/migration, and alterations in public order have resulted in changes in food security, food culture, and physical activity practices, affecting the onset of obesity. Notably, distinctions in cultural beliefs regarding food culture and health as factors influencing obesity were observed between Afro-Colombians and the Indigenous populations; however, educational differences within the same racial ethnic group were not predominant. Findings indicate obesity is influenced by cultural, social, and biobehavioural factors, especially in regions with racial-ethnic communities facing complex conditions, necessitating targeted racial-ethnic public health policies.

The developmental origins of health and disease hypothesis have highlighted the link between early life environment and long-term health outcomes in offspring. For example, maternal protein restriction during pregnancy and lactation can result in adverse metabolic and cognitive outcomes in offspring postnatal. Hence, in the present study, we assess whether an isocaloric low-protein diet (ILPD) affects the fatty acid profile in breast milk, the hippocampal synaptophysin (Syn) ratio, and the oxidative stress markers in the neonatal stage of male and female offspring. The aim of this work was to assess the effect of an ILPD on the fatty acid profile in breast milk, quantified the hippocampal synaptophysin (Syn) ratio and oxidative stress markers in neonatal stage of male and female offspring. Female Wistar rats were fed with either a control diet or an ILPD during gestation to day 10 of lactation. Oxidative stress markers were assessed in serum and liver. All quantifications were done at postnatal day 10. The results showed: ILPD led to decreases of 38.5% and 17.4% in breast milk volume and polyunsaturated fatty acids content. Significant decreases of hippocampal Syn ratio in male offspring (decreases of 98% in hippocampal CA1 pyramidal and CA1 oriens, 83%, stratum pyramidal in CA3, 80%, stratum lucidum in CA3, and 81% stratum oriens in CA3). Male offspring showed an increase in pro-oxidant status in serum and liver. Thus, the data suggest that male offspring are more vulnerable than females to an ILPD during gestation and lactation.

There has been limited focus placed on exploring food insecurity within the UK-ex-Armed Forces population. The present study aims to build on initial work by investigating the prevalence and associated factors of food insecurity within UK veterans and their families and their current health status. 881 veterans (or a family member) who previously served in the Royal Navy and Royal Marines, Army and the Royal Air Force completed an online survey to explore health status, food insecurity and receipt of benefits. In total, 16.9% of survey respondents were part of food-insecure households, with 12% of these also experiencing some element of hunger. Working age, non-officer rank at the time of service discharge, not being married, living in rented accommodation, having at least one medical condition and in receipt of other benefits were significant risk factors associated with food insecurity. Understanding the specific risk factors associated with food insecurity is vital to develop personalised interventions and policies, such as income support programmes and affordable housing initiatives. However, more work is needed to further explore the factors associated with food insecurity, particularly in the long term.

Online food delivery applications (OFDAs) have seen a surge in popularity during the COVID-19 Pandemic, particularly among young adults. This study aimed to assess the use of OFDAs and the perception of food healthiness and safety among university students in the United Arab Emirates (UAE). A web-based cross-sectional study was conducted among university students in the UAE via snowball sampling (n = 1096). Sociodemographic characteristics, OFDAs usage, and perceptions toward food healthiness and safety were investigated. Chi-square analysis was used to determine the association between categorical variables and healthy food choices. Mann-Whitney U and Kruskal-Wallis H tests were used to determine differences between different groups and perception statements. Over half (52%) of the students were frequent users of OFDAs with fast food being the most popular choice (88.4%). Older participants, those living in the university dorms, and those with higher allowances used the OFDAs more frequently (P < 0.05). Price (78.0%) and food appearance (65.7%) had the highest impact on food selection. Most subjects (69.3%) reported looking for healthy food but were worried about affordability (43.1%) and taste (27.1%). Most participants (57.8%) agreed that OFDAs increased their appetite and food intake. Participants believed that having a hygiene rating system in OFDAs would give them the chance to make informed decisions (82.3%). Unhealthy food options were popular among university students. The study highlights the need to provide more affordable and appealing healthy food options and suggests that improved nutrition information and hygiene standards could help to promote healthy food choices among university students.
在线食品配送应用程序(OFDAs)在 COVID-19 大流行期间大受欢迎,尤其是在年轻人中。本研究旨在评估阿拉伯联合酋长国(UAE)大学生对在线食品配送应用程序的使用情况以及对食品健康和安全的看法。通过滚雪球式抽样(n = 1096),在阿联酋的大学生中开展了一项基于网络的横断面研究。研究调查了社会人口特征、OFDA 的使用情况以及对食品健康和安全的看法。采用卡方分析确定分类变量与健康食品选择之间的关系。Mann-Whitney U 和 Kruskal-Wallis H 检验用于确定不同群体和认知陈述之间的差异。超过一半(52%)的学生经常使用开放式自助餐厅,其中快餐是最受欢迎的选择(88.4%)。年龄较大、住在大学宿舍和津贴较高的参与者更经常使用开放式自助餐厅(P < 0.05)。价格(78.0%)和食物外观(65.7%)对食物选择的影响最大。大多数受试者(69.3%)表示要寻找健康食品,但担心负担能力(43.1%)和口味(27.1%)。大部分受访者(57.8%)同意开放式食物局能增加他们的食欲和食物摄入量。參加者認為在自助售賣機設立衞生評級制度可讓他們作出明智的決定(82.3%)。不健康的食物在大学生中很受欢迎。这项研究强调,有必要提供更多经济实惠、更具吸引力的健康食品选择,并建议改善营养信息和卫生标准,有助于促进大学生选择健康食品。

This research validated an Arabic version of the Psychological General Well-being Index-Short version (PGWB-S) and examined the relationship between perceived psychological well-being, and food insecurity, academic achievement, and other risk factors in a sample of university students in Amman, Jordan, during COVID-19. A cross-sectional study was conducted in two phases. Phase 1 translated and validated the Arabic copy of the PGWB-S in 122 students from the University of Jordan. In Phase 2, 414 students completed the demographic questionnaire, Arabic versions of the PGWB-S, the Ryff Psychological Well-being Scale, and the Individual Food Insecurity Experience Scale. The participants had a mean PGWB-S score of 15.82 ± 0.34, and 41.3% had a mean score below 15. Psychological well-being was better in students younger than 21 and/or who had a GPA ≥3.0, were of normal weight or overweight, physically inactive, and food secure, did not drink coffee or smoke, as well as in those whose neighbourhood contained grocery stores and/or public transportation (P < 0.05). In conclusion, during the pandemic, perceived mental well-being was moderate in a Jordanian sample of university students. Perceived psychological well-being was also positively associated with food security and academic performance. These findings suggest that improving food security and academic achievement may contribute to enhanced psychological well-being among university students. Therefore, higher education institutions with the help of the government are encouraged to facilitate the provision of mental health care services to students, mainly post the coronavirus, which according to our knowledge is limited.

The aim of this study was to explore the associations between diet quality, socio-demographic measures, smoking, and weight status in a large, cross-sectional cohort of adults living in Yorkshire and Humber, UK. Data from 43, 023 participants aged over 16 years in the Yorkshire Health Survey, 2nd wave (2013-2015) were collected on diet quality, socio-demographic measures, smoking, and weight status. Diet quality was assessed using a brief, validated tool. Associations between these variables were assessed using multiple regression methods. Split-sample cross-validation was utilised to establish model portability. Observed patterns in the sample showed that the greatest substantive differences in diet quality were between females and males (3.94 points; P < 0.001) and non-smokers vs smokers (4.24 points; P < 0.001), with higher diet quality scores observed in females and non-smokers. Deprivation, employment status, age, and weight status categories were also associated with diet quality. Greater diet quality scores were observed in those with lower levels of deprivation, those engaged in sedentary occupations, older people, and those in a healthy weight category. Cross-validation procedures revealed that the model exhibited good transferability properties. Inequalities in patterns of diet quality in the cohort were consistent with those indicated by the findings of other observational studies. The findings indicate population subgroups that are at higher risk of dietary-related ill health due to poor quality diet and provide evidence for the design of targeted national policy and interventions to prevent dietary-related ill health in these groups. The findings support further research exploring inequalities in diet quality in the population.

The neutropenic diet (ND) is often recommended to people with cancer to reduce infection risk despite recommendations of clinical guidelines advising against its use. While recent literature suggests the ND does not reduce infection risk, other outcomes related to health, nutrition, and lifestyle are unknown. The aim of this review is to systematically scope the literature on the ND in people with cancer for all outcomes related to clinical health, nutrition, and lifestyle. Scientific databases were systematically searched. Eligible studies were in English, people with any cancer type, consuming an ND, any age group, date, or setting. Eligible study types were randomised control trials, observational studies, systematic reviews, and meta-analyses. Twenty-one studies met the inclusion criteria. Outcomes of interest found were infection rates, fever, mortality, antibiotic use, gastrointestinal side effects, comorbidities, biochemistry, hospitalisation, nutritional status, quality of life (QoL), well-being, and financial costs. Most research has focused on infection and mortality rates with few assessing hospitalisation rates, nutritional status, financial costs, and QoL. Most included studies found no significant differences between ND and comparator diet for mortality, antibiotics use, comorbidities, and QoL; however, several studies reported the ND significantly increased the risk of infection. Gaps in the literature included effect of ND on QoL in an adult population, microbiome, lifestyle changes, and financial burden. Further research is needed regarding how the ND affects the microbiome and QoL of its consumers, but in the interim, it is important for hospitals providing an ND to their patients to liberalise the ND wherever possible.
尽管临床指南建议不要使用中性粒细胞饮食(ND),但为了降低感染风险,人们还是经常向癌症患者推荐这种饮食。虽然最近的文献表明 ND 不会降低感染风险,但与健康、营养和生活方式相关的其他结果尚不清楚。本综述旨在系统地研究有关癌症患者使用 ND 的文献,以了解与临床健康、营养和生活方式相关的所有结果。我们系统地搜索了科学数据库。符合条件的研究为英文研究,研究对象为任何癌症类型、食用 ND、任何年龄段、任何日期或任何环境的癌症患者。符合条件的研究类型包括随机对照试验、观察性研究、系统综述和荟萃分析。21 项研究符合纳入标准。所发现的相关结果包括感染率、发热、死亡率、抗生素使用、胃肠道副作用、合并症、生化、住院、营养状况、生活质量(QoL)、幸福感和经济成本。大多数研究侧重于感染率和死亡率,很少有研究对住院率、营养状况、经济成本和 QoL 进行评估。大多数纳入的研究发现,在死亡率、抗生素使用、并发症和 QoL 方面,玖龙纸业与对比饮食之间没有明显差异;但有几项研究报告称,玖龙纸业会显著增加感染风险。文献中的空白包括 ND 对成年人群 QoL 的影响、微生物组、生活方式的改变以及经济负担。关于玖龙牌如何影响其消费者的微生物组和 QoL,还需要进一步研究,但在此期间,为患者提供玖龙牌的医院必须尽可能放开玖龙牌。

Maternal malnutrition is pervasive throughout the world, notably in sub-Saharan Africa, including Ethiopia. This study examined the effect of community-based iron-folic acid supplementation (IFAS) nutrition education on IFAS knowledge and attitude among pregnant women in urban settings in South Ethiopia. A community-based quasi-experimental study was conducted among 198 randomly selected pregnant women attending antenatal care (ANC) (99 intervention and 99 control). We used a multistage sampling technique followed by systematic sampling to select the pregnant women. Pregnant women who participated in the intervention arm received six nutrition education sessions and counselling using a health belief model (HBM), while the control group received only routine ANC services. Baseline and endline data were collected during the ANC and compared. The data was analysed using statistical package for social sciences. Analyses of the effect of the intervention were done using difference-in-difference and generalised estimation equation to allow correlation of repeated observations over time. The results indicated a significant effect of intervention on maternal knowledge towards IFAS; with intervention, group levels increased by 35 percentage points (P < 0.001). The odds of being knowledgeable at the endpoint in the intervention group were 2.6 times higher than baseline (OR = 2.67, 95% CI 1.88-3.80). There was a significant (P = 0.001) change in proportion with a favourable attitude towards IFAS between the two time points. The community-based nutrition education intervention approach has significantly improved maternal knowledge and a favourable attitude towards IFAS among pregnant women. The HBM is effective in improving knowledge and attitude among pregnant women.
