Study finds that genetically determined milk intake does not increase type-2 diabetes risk SyddanskUni research diabetes typetwodiabetes T2D type2diabetes geneticdisposition
By Dr. Chinta SidharthanJul 3 2023Reviewed by Lily Ramsey, LLM In a recent study published in the Nutrition, Metabolism and Cardiovascular Diseases Journal, researchers systematically reviewed various Mendelian randomization studies to investigate the association between the genetic basis of milk consumption and type 2 diabetes risk.
Milk consumption is a dietary exposure that has been extensively investigated regarding type 2 diabetes risk, with various studies finding no correlation between the consumption of milk and type 2 diabetes risk but finding a negative correlation between total dairy consumption and diabetes risk. Related StoriesThe lactase enzyme breaks down the lactose in milk into galactose and glucose, which are absorbed into the bloodstream. The transcriptional activation of the gene coding for the lactase enzyme, LCT, is influenced by a variant in the intronic region of a neighboring gene.
Studies that did not use the Mendelian randomization approach or included other exposures apart from milk consumption were excluded from the review, as were studies that did not examine type 2 diabetes as an outcome.

Dysregulation of iron homeostasis in airways associated with persistent preschool wheezing - Respiratory ResearchBackground Currently, there are no reliable clinical tools available to identify persistent asthma symptoms among preschool children with recurrent wheezing. We investigated iron homeostasis in the airways of preschoolers with recurrent wheezing and assessed whether iron homeostasis-related indices may reliably predict persistent wheezing. Methods Iron levels and mRNA expression levels of iron homeostasis molecules were examined in bronchoalveolar lavage samples from 89 preschoolers with recurrent wheezing and 56 controls, with a 12-month follow-up conducted. Risk factors for persistent wheezing were identified using least absolute shrinkage and selection operator and multivariate logistic regression. The addition of predictive values of iron indices to the modified Asthma Predictive Index (mAPI) or clinical predictors was determined using area under receiver operating characteristic curves (AUC). Results Preschoolers with recurrent wheezing had reduced iron levels in their airways, associated with significantly decreased expression of iron export molecule SLC40A1 and increased expression of iron intake factor TFR1 and iron storage factors FTH and FTL. Risk factors for persistent wheezing included mAPI positivity, iron predictors (lower expression of SLC40A1 and higher expression of FTL), and clinical predictors (aeroallergen sensitivity, shorter breastfeeding duration, and earlier age of first wheezing episode). The addition of information on iron predictors significantly enhanced the power of clinical predictors (AUC: 84%, increase of 12%) and mAPI (AUC: 81%, increase of 14%). Conclusions Iron homeostasis is altered in the airways of preschoolers with recurrent wheezing. Adding information on iron-related indices to clinical information significantly improves accurate prediction of persistent wheezing in preschool-aged children.

“They want you to know who they really are inside of the old visage”—biographical storytelling as a methodological tool to explore emotional challenges in old age - BMC GeriatricsBackground Growing older is often associated with resilience, contentedness and inner growth. Older people however are also at risk of confronting unique emotional challenges as a result of varied ageing-related experiences. By employing a biographical lens, we aim to introduce storytelling as a methodological tool to more holistically explore older people’s emotional challenges and to improve their wellbeing. Methods Building upon theoretical understandings about the narrative construction of identity across the life span, we draw upon a qualitative study about older people’s loneliness as an example to showcase the methodological value and feasibility of biographical storytelling. We aim to better understand the nuanced and sometimes painful emotional experiences that can be encountered alongside ageing. Results Findings from the qualitative study we showcase, highlight that unique emotional pains and the (in)ability to deal with such in old age could be deeply rooted in older people’s earlier lives. These findings contextualise people’s emotional challenges and needs within their identity, as a narrative thread that links their past, present and expected future. As such, our example study shows that emotional challenges in old age are not only ageing-related, but can be more fundamentally connected to disruptions to the ongoing flow of narrative identity construction. Conclusion The highly retrospective and reflexive nature of these findings illustrates the methodological merit of biographical storytelling. We argue that the impact of biographical storytelling can go further than both conventional semi-structured narrative interviews and existing interventional tools. Instead, it is a particularly useful research methodology to explore human experiences and needs in the unique context of ageing. This methodological development thus provides an insightful analytical lens to explore how older people’s earlier life experiences may be carried forward and confronted t

Determinants of health-related quality of life among patients with systemic lupus erythematosus in Hanoi, Vietnam - BMC RheumatologyBackground Systemic lupus erythematosus (SLE) is a chronic autoimmune disease which impacts patients’ lives. Many studies in high-income countries have focused on their health-related quality of life (HRQoL). However, evidence of awareness of SLE and HRQoL in low- and middle-income countries is lacking. Therefore, this study aimed to identify the determinants of HRQoL of SLE patients in Vietnam, a lower-middle income country. Methods This cross-sectional study was conducted at the National Hospital of Dermatology and Venereology in 2019. A pre-tested structured questionnaire was used to collect data. It consisted of Short Form-36 to assess HRQoL which comprised physical and mental component summaries, Multidimensional Scale of Perceived Social Support, Satisfaction with Life Scale, and Mental Adjustment to SLE. Multiple linear regression was used to identify the determinants of HRQoL. Results One hundred thirty four patients with SLE participated in this study. The majority of the patients were women (n = 126, 94.0%). The mean age of all participants was 37.9 years old (standard deviation [SD] 12.5). Of 134 participants, 104 (77.6%) were married. Older patients were more likely to have a lower score of mental component summary (B=-0.45, 95% CI -0.73, -0.17). Patients with more children were more likely to have a lower score of physical component summary (B=-5.14, 95% CI -9.27, -1.00). Patients who felt more helplessness or hopelessness were more likely to have lower scores of physical and mental component summaries (B=-1.85, 95% CI -2.80, -0.90; B=-1.69, 95% CI -2.57, -0.81). Also, patients who felt more anxious were more likely to have a lower score of mental component summary (B=-1.04, 95% CI -1.77, -0.32). Patients who were more satisfied with their lives were more likely to have higher scores of physical and mental component summaries (B = 1.07, 95% CI 0.50, 1.64; B = 1.08, 95% CI 0.55, 1.61). Conclusion Factors associated with lower HRQoL in Vietnam were feelin
