Phospho-regulated Bim1/EB1 interactions trigger Dam1c ring assembly at the budding yeast outer kinetochore.

Kinetochores form the link between chromosomes and microtubules of the mitotic spindle. The heterodecameric Dam1 complex (Dam1c) is a major component of the Saccharomyces cerevisiae outer kinetochore, assembling into 3 MDa-sized microtubule-embracing rings, but how ring assembly is specifically initiated in vivo remains to be understood. Here, we describe a molecular pathway that provides local control of ring assembly during the establishment of sister kinetochore bi-orientation. We show that Dam1c and the general microtubule plus end-associated protein (+TIP) Bim1/EB1 form a stable complex depending on a conserved motif in the Duo1 subunit of Dam1c. EM analyses reveal that Bim1 crosslinks protrusion domains of adjacent Dam1c heterodecamers and promotes the formation of oligomers with defined curvature. Disruption of the Dam1c-Bim1 interaction impairs kinetochore localization of Dam1c in metaphase and delays mitosis. Phosphorylation promotes Dam1c-Bim1 binding by relieving an intramolecular inhibition of the Dam1 C-terminus. In addition, Bim1 recruits Bik1/CLIP-170 to Dam1c and induces formation of full rings even in the absence of microtubules. Our data help to explain how new kinetochore end-on attachments are formed during the process of attachment error correction.

Effect of the DASH diet on the sodium-chloride cotransporter and aquaporin-2 in urinary extracellular vesicles.

The dietary approach to stop hypertension (DASH) diet combines the antihypertensive effect of a low sodium and high potassium diet. In particular, the potassium component of the diet acts as a switch in the distal convoluted tubule to reduce sodium reabsorption, similar to a diuretic but without the side effects. Previous trials to understand the mechanism of the DASH diet were based on animal models and did not characterize changes in human ion channel protein abundance. More recently, protein cargo of urinary extracellular vesicles (uEVs) has been shown to mirror tissue content and physiological changes within the kidney. We designed an inpatient open label nutritional study transitioning hypertensive volunteers from an American style diet to DASH diet to examine physiological changes in adults with stage 1 hypertension otherwise untreated (Sacks FM, Svetkey LP, Vollmer WM, Appel LJ, Bray GA, Harsha D, Obarzanek E, Conlin PR, Miller ER 3rd, Simons-Morton DG, Karanja N, Lin PH; DASH-Sodium Collaborative Research Group. N Engl J Med 344: 3-10, 2001). Urine samples from this study were used for proteomic characterization of a large range of pure uEVs (small to large) to reveal kidney epithelium changes in response to the DASH diet. These samples were collected from nine volunteers at three time points, and mass spectrometry identified 1,800 proteins from all 27 samples. We demonstrated an increase in total SLC12A3 [sodium-chloride cotransporter (NCC)] abundance and a decrease in aquaporin-2 (AQP2) in uEVs with this mass spectrometry analysis, immunoblotting revealed a significant increase in the proportion of activated (phosphorylated) NCC to total NCC and a decrease in AQP2 from day 5 to day 11. This data demonstrates that the human kidney's response to nutritional interventions may be captured noninvasively by uEV protein abundance changes. Future studies need to confirm these findings in a larger cohort and focus on which factor drove the changes in NCC and AQP2, to which degree NCC and AQP2 contributed to the antihypertensive effect and address if some uEVs function also as a waste pathway for functionally inactive proteins rather than mirroring protein changes.NEW & NOTEWORTHY Numerous studies link DASH diet to lower blood pressure, but its mechanism is unclear. Urinary extracellular vesicles (uEVs) offer noninvasive insights, potentially replacing tissue sampling. Transitioning to DASH diet alters kidney transporters in our stage 1 hypertension cohort: AQP2 decreases, NCC increases in uEVs. This aligns with increased urine volume, reduced sodium reabsorption, and blood pressure decline. Our data highlight uEV protein changes as diet markers, suggesting some uEVs may function as waste pathways. We analyzed larger EVs alongside small EVs, and NCC in immunoblots across its molecular weight range.

Hypothetical 22-Year Intervention With the Dietary Approaches to Stop Hypertension and Risk of Heart Failure in a General Population.

We used design principles of target trial methodology to emulate the effect of sustained adherence to the Dietary Approaches to Stop Hypertension (DASH) diet on the 22-year risk of heart failure. Women and men aged 45-83 years without previous heart failure, who answered questionnaires in 1997 from the Swedish Mammography Cohort and the Cohort of Swedish Men, were eligible. Follow-up questionnaires were sent in 2008-2009. Incidence of heart failure was ascertained using the Swedish Patient Register, updated until December 31, 2019. The parametric g-formula was used to estimate the 22-year risk of heart failure under sustained adherence to a population-adapted DASH diet compared with no intervention. Intakes before 1997 for before-baseline adjustment was available only for women. In total, 31,238 women and 34,939 men were eligible. The 22-year risk of heart failure was 14.5% with long-term adherence to the DASH diet compared with 15.2% with no intervention (risk difference = -0.7%, 95% confidence interval: 1.6, 0.0%) in women and correspondingly in men 15.3% vs. 16.2% (risk difference = -0.9%, 95% confidence interval: -1.6, -0.2%). Our hypothetical intervention suggests that sustained adherence to the population-adapted DASH diet may reduce risk of heart failure in middle-aged and elderly Swedish women and men.

Rapidly-manufactured CD276 CAR-T cells exhibit enhanced persistence and efficacy in pancreatic cancer.

BACKGROUND: Pancreatic cancer is one of the most lethal malignancies and the lack of treatment options makes it more deadly. Chimeric Antigen Receptor T-cell (CAR-T) immunotherapy has revolutionized cancer treatment and made great breakthroughs in treating hematological malignancies, however its success in treating solid cancers remains limited mainly due to the lack of tumor-specific antigens. On the other hand, the prolonged traditional manufacturing process poses challenges, taking 2 to 6 weeks and impacting patient outcomes. CD276 has recently emerged as a potential therapeutic target for anti-solid cancer therapy. Here, we investigated the efficacy of CD276 CAR-T and rapidly-manufactured CAR-T against pancreatic cancer. METHODS: In the present study, CD276 CAR-T was prepared by CAR structure carrying 376.96 scFv sequence, CD8 hinge and transmembrane domain, 4-1BB and CD3ζ intracellular domains. Additionally, CD276 rapidly-manufactured CAR-T (named CD276 Dash CAR-T) was innovatively developed by shortening the duration of ex vitro culture to reduce CAR-T manufacturing time. We evaluated the anti-tumor efficacy of CD276 CAR-T and further compared the functional assessment of Dash CAR-T and conventional CAR-T in vitro and in vivo by detecting the immunophenotypes, killing ability, expansion capacity and tumor-eradicating effect of CAR-T. RESULTS: We found that CD276 was strongly expressed in multiple solid cancer cell lines and that CD276 CAR-T could efficiently kill these solid cancer cells. Moreover, Dash CAR-T was successfully manufactured within 48-72 h and the functional validation was carried out subsequently. In vitro, CD276 Dash CAR-T possessed a less-differentiated phenotype and robust proliferative ability compared to conventional CAR-T. In vivo xenograft mouse model, CD276 Dash CAR-T showed enhanced anti-pancreatic cancer efficacy and T cell expansion. Besides, except for the high-dose group, the body weight of mice was maintained stable, and the state of mice was normal. CONCLUSIONS: In this study, we proved CD276 CAR-T exhibited powerful activity against pancreatic cancer cells in vitro and in vivo. More importantly, we demonstrated the manufacturing feasibility, acceptable safety and superior anti-tumor efficacy of CD276 Dash CAR-T generated with reduced time. The results of the above studies indicated that CD276 Dash CAR-T immunotherapy might be a novel and promising strategy for pancreatic cancer treatment.

Adherence to the Dietary Approaches to Stop Hypertension (DASH) and Serum Urate Concentrations: A Longitudinal Analysis from the Brazilian Longitudinal Study of Adult Health (ELSA-Brasil).

BACKGROUND: Increased serum urate (SU) and hyperuricemia (HU) are associated with chronic noncommunicable diseases and mortality. SU concentrations are affected by several factors, including diet, and are expected to rise with age. We investigated whether the Dietary Approaches to Stop Hypertension (DASH) diet alter this trend. OBJECTIVE: The objective was to assess whether adherence to the DASH diet predicts a longitudinal change in SU concentrations and risk of HU in 8 y of follow-up. METHODS: Longitudinal analyses using baseline (2008-2010, aged 35-74 y), second (2012-2014), and third (2016-2018) visits data from the Brazilian Longitudinal Study of Adult Health (ELSA-Brasil). The inclusion criteria were having complete food frequency questionnaire (FFQ) and urinary sodium measurement, in addition to having SU measurement at the 1st visit and at least 1 of the 2 follow-up visits. For the HU incidence analyses, participants had also to be free from HU at baseline. The final samples included 12575 individuals for the SU change analyses and 10549 for the HU incidence analyses. Adherence to DASH diet was assessed as continuous value. HU was defined as SU>6.8 mg/dL and/or urate-lowering therapy use. Mixed-effect linear and Poisson regressions (incidence rate ratio [IRR] and 95% confidence interval [CI]) were used in the analyses, adjusted for confounders. RESULTS: The mean age was 51.4 (8.7) y, and 55.4% were females. SU means (standard deviation) were 5.4 (1.4) at 1st visit, 5.2 (1.4) at 2nd visit, and 5.1(1.3) mg/dL at 3rd visit. The HU incidence rate was 8.87 per 1000 person-y. Each additional point in adherence to the DASH diet accelerated SU decline (P< 0.01) and lowered the incidence of HU by 4.3% (IRR: 0.957; 95% CI: 0.938,0.977) in adjusted model. CONCLUSION: The present study findings reinforce the importance of encouraging the DASH diet as a healthy dietary pattern to control and reduce the SU concentrations and risk of HU.

Diet Quality, Sedentary Time, and Blood Pressure in the POUCHmoms Study.

BACKGROUND: Elevated blood pressure (BP) is a major contributor to cardiovascular disease in womens; diet and sedentary time (ST) are modifiable lifestyle factors thought to influence BP. OBJECTIVES: The aim of this study was to examine 2 diet-quality measures and ST in relation to BP among parous womens. METHODS: This cross-sectional analysis uses data from 677 womens (age 25-55 y) enrolled in the Pregnancy Outcomes and Community Health (POUCH) Study and followed up in the POUCHmoms study 7-15 y after delivery (2011 and 2014). Follow-up measures included a food-frequency questionnaire (FFQ), self-report of ST (occupational and leisure), and systolic and diastolic blood pressure (SBP and DBP, respectively). The FFQ was used to calculate 2 diet-quality measures, Alternative Healthy Eating Index-2010 (AHEI) and Dietary Approaches to Stop Hypertension (DASH). Total ST h/wk was dichotomized at the median and labeled "low" or "high." In weighted unadjusted and adjusted regression models, BP was assessed in relation to diet scores (linear and threshold associations) and combinations of dichotomized diet-quality scores ("poor" = lowest quartile compared with "not poor" = upper 3 quartiles) and ST. RESULTS: Higher mean SBP and DBP occurred mainly in women with a '"poor" diet-quality score (AHEI and DASH). Among womens with a "poor"-quality diet (on the basis of the AHEI score) and "high" ST, (N = 93) adjusted mean SBP and DBP were 4.5 mmHg and 4.4 mmHg higher, respectively, than that of the counterparts who did not have a poor-quality diet and had "low" ST (N = 275). Results were similar in analyses using the DASH diet score. CONCLUSIONS: Women with poor-quality diets and more ST may need closer BP monitoring. Even modest improvements in womens' diet quality and reductions in ST might help lower their BP, but this observation needs testing in prospective studies..

Dietary patterns and cardiorespiratory fitness in midlife and subsequent all-cause dementia: findings from the cooper center longitudinal study.

BACKGROUND: Identifying lifestyle factors that independently or jointly lower dementia risk is a public health priority given the limited treatment options available to patients. In this cohort study, we examined the associations between Mediterranean or Dietary Approaches to Stop Hypertension (DASH) diet adherence and cardiorespiratory fitness (CRF) with later-life dementia, and assessed whether the associations between dietary pattern and dementia are modified by CRF. METHODS: Data are from 9,095 adults seeking preventive care at the Cooper Clinic (1987-1999) who completed a 3-day dietary record and a maximal exercise test. Alzheimer's disease and related disorders or senile dementia (i.e., all-cause dementia) was identified from Medicare administrative claims (1999-2019). Illness-death models were used to estimate hazard ratios (HRs) and 95% confidence intervals (CIs) for the associations between Mediterranean or DASH diet adherence (primary exposure), CRF (secondary exposure), and all-cause dementia, adjusted for demographic and clinical factors. An interaction term was included between diet score and CRF to assess effect modification by CRF. RESULTS: The mean age at baseline was 50.6 (standard deviation [SD]: 8.4) years, and a majority of the study sample were men (77.5%) and White (96.4%). 1449 cases of all-cause dementia were identified over a mean follow-up of 9.2 (SD: 5.8) years. Neither Mediterranean nor DASH diet adherence was associated with dementia risk in fully adjusted models (HR per SD of Mediterranean diet score: 1.00, 95% CI: 0.94, 1.05; HR per SD of DASH diet score: 1.02, 95% CI: 0.96, 1.08). However, participants with higher CRF had a decreased hazard of dementia (HR, per metabolic equivalent of task [MET] increase, Mediterranean model: 0.95, 95% CI: 0.92, 0.98; HR, per MET increase, DASH model: 0.96, 95% CI: 0.92, 0.97). No effect modification by CRF was observed in the association between diet and dementia. CONCLUSIONS: In this sample of apparently healthy middle-aged adults seeking preventive care, higher CRF at midlife was associated with a lower risk of all-cause dementia, though adherence to a Mediterranean or DASH diet was not, and CRF did not modify the diet-dementia association. CRF should be emphasized in multimodal interventions for dementia prevention and investigated among diverse samples.

The blood pressure control effect of the sodium-restricted dietary approaches to stop hypertension diet: a systematic review.

The Dietary Approaches to Stop Hypertension (DASH) diet is highly effective in controlling blood pressure (BP). Although Na restriction is not a primary focus within the DASH diet, it is recommended that it be added to control BP. Therefore, we aimed to systematically review the characteristics and BP-lowering effects of Na-restricted DASH diet interventions. We searched thirteen databases, namely, MEDLINE, Embase, Cochrane Central Register of Controlled Trials, KoreaMed, KISS, KMbase, RISS, CINAHL, Scopus, ClinicalTrials.gov, Grey Literature Report, OpenGrey and PQDT Global, for articles published through May 2023. The randomised controlled trials assessing the BP-lowering effect of the Na-restricted DASH diet in adults aged 18 years and older were included. The study protocol was registered in the PROSPERO registry (CRD42023409996). The risk of bias in the included studies was also assessed. Nine articles were included in this review. Interventions were categorised into three types: feeding, provision and education, and the study results were compared by intervention type. BP was significantly reduced in two of the three feeding studies, one of the three provisional studies and none of the educational studies. In eight studies, effect sizes varied among both systolic BP (-7·7 to -2·4) and diastolic BP (-8·3 to 0·1). Six studies showed an overall high risk of bias. In conclusion, Na-restricted DASH may have beneficial effects on BP control. Additionally, compared with control interventions, feeding interventions appeared to have a greater BP-lowering effect. Further high-quality studies are needed to improve the quality of the evidence.

Towards consistency in dietary pattern scoring: standardising scoring workflows for healthy dietary patterns using 24-h recall and two variations of a food frequency questionnair.

Healthy dietary patterns such as the Mediterranean diet (MeDi), Dietary Approaches to Stop Hypertension (DASH) and the Mediterranean-DASH Intervention for Neurodegenerative Delay (MIND) have been evaluated for their potential association with health outcomes. However, the lack of standardisation in scoring methodologies can hinder reproducibility and meaningful cross-study comparisons. Here we provide a reproducible workflow for generating the MeDi, DASH and MIND dietary pattern scores from frequently used dietary assessment tools including the 24-h recall tool and two variations of FFQ. Subjective aspects of the scoring process are highlighted and have led to a recommended reporting checklist. This checklist enables standardised reporting with sufficient detail to enhance the reproducibility and comparability of their outcomes. In addition to these aims, valuable insights in the strengths and limitations of each assessment tool for scoring the MeDi, DASH and MIND diet can be utilised by researchers and clinicians to determine which dietary assessment tool best meets their needs.

Dietary approaches to stop hypertension (DASH) diet improves hepatic fibrosis, steatosis and liver enzymes in patients with non-alcoholic fatty liver disease: a randomized controlled trial.

PURPOSE: Recent evidence suggests that adherence to dietary approaches to stop hypertension (DASH) diet can be effective in managing non-alcoholic fatty liver disease (NAFLD). We investigated the effect of DASH diet on hepatic fibrosis, steatosis and liver enzymes in patients with NAFLD. METHODS: This 12-week randomized controlled trial was conducted among seventy patients with NAFLD who were randomly assigned into two groups including intervention group (DASH diet containing 50-55% carbohydrate, 15-20% protein, and 30% total fat) and the control group (a healthy diet containing 50-55% carbohydrate, 15-20% protein, and 30% total fat). Both diets were calorie-restricted (500-700 kcal lower than the energy requirement). The primary outcomes included hepatic fibrosis, hepatic steatosis, alanine transaminase (ALT), aspartate transaminase (AST) and gamma-glutamyl transpeptidase (GGT). RESULTS: At the baseline, there was no significant difference between two groups in the level of hepatic fibrosis (P = 0.63), hepatic steatosis (P = 0.53), ALT (P = 0.93), AST (P = 0.18) and GGT (P = 0.76). A significant reduction was found in the intervention group compared to the control group in hepatic fibrosis (23 grades reduction vs. 7 grades reduction; P = 0.008) and hepatic steatosis (31 grades reduction vs. 9 grades reduction; P = 0.03) after intervention. In addition, a significant change was observed in the intervention group compared to control group in ALT ( - 8.50 ± 8.98 vs. - 2.09 ± 7.29; P = 0.002), and AST ( - 5.79 ± 6.83 vs. - 0.51 ± 6.62; P = 0.002). CONCLUSIONS: Adherence to DASH diet may be effective in management of NAFLD. TRIAL REGISTRATION: The trial was registered on 06 February 2022 at Iranian Registry of Clinical Trials (IRCT20170117032026N3) with URL: https://www.irct.ir/trial/60887 .

Chinese-modified MIND Diet and subjective well­being in adults aged 60 years or older in China: a national community-based cohort study.

OBJECTIVE: Observing the dietary principles of the Mediterranean-DASH Intervention for Neurodegenerative Delay (MIND) diet has exhibited an association with a diminished occurrence of diverse ailments, enhanced mental well-being, and extended longevity. Nevertheless, current literature is deficient in terms of investigating the link between the MIND diet and subjective well-being (SWB) specifically in older adults. Hence, this study endeavors to examine the correlation between adhering to a Chinese-modified Mediterranean-DASH Intervention for Neurodegenerative Delay (cMIND) diet and SWB in the older Chinese adults, taking into account the unique dietary attributes of the Chinese population. METHODS: Using data from the latest four waves of the Chinese Longitudinal Healthy Longevity Survey. Multiple linear regression and multinomial ordered logistic regression were employed to examine the relationship between the duration of adherence to cMIND diet and SWB in Chinese older adults. RESULTS: The results indicated a significant association between the duration of adherence to cMIND diet and SWB (1 ∼ 6 years: B = 0.907, 95%CI = 0.508 ∼ 1.307, P < 0.001; 7 ∼ 9 years: B = 1.286, 95%CI = 0.767 ∼ 1.805, P < 0.001; 10 years and above: B = 2.320, 95%CI = 1.677 ∼ 2.963, P < 0.001). The longer the duration of adherence to cMIND diet, the higher the scores for life satisfaction (B = 0.184, 95%CI = 0.110 ∼ 0.259; B = 0.312, 95%CI = 0.217 ∼ 0.407; B = 0.321, 95%CI = 0.193 ∼ 0.448), positive affect (B = 0.434, 95%CI = 0.209 ∼ 0.658; B = 0.701, 95%CI = 0.400 ∼ 1.003; B = 1.167, 95%CI = 0.775 ∼ 1.559), and negative affect (B = 0.289, 95%CI = 0.078 ∼ 0.500; B = 0.832, 95%CI = 0.479 ∼ 1.185), suggesting a higher SWB score. Sensitivity analysis further supports our findings. CONCLUSION: Considering the poor knowledge, attitudes, and behaviors related to diet among Chinese adults, especially older adults, it is imperative to implement dietary policies that promote SWB in older adults to enhance their happiness in later life.

The effect of dietary approaches to stop hypertension (DASH) diet on fatty liver and cardiovascular risk factors in subjects with metabolic syndrome: a randomized controlled trial.

BACKGROUND: Metabolic syndrome (MetS) as a multifactorial disorder is associated with non-communicable diseases. The dietary approaches to stop hypertension (DASH) diet is a healthy dietary pattern. We investigated the effect of the DASH diet on fatty liver and cardiovascular risk factors in subjects with MetS. METHODS: 60 Subjects with MetS were assigned into the intervention group (DASH diet) or the control group (a healthy diet). Fatty liver index (FLI), hepatic steatosis index (HSI), waist circumference (WC), weight, body mass index (BMI), triglyceride (TG), total cholesterol (TC), low-density lipoprotein cholesterol (LDL-c) and high-density lipoprotein cholesterol (HDL-c) were evaluated at the beginning and after intervention. Equations of fatty liver indices such as FLI and HSI are based on liver enzymes, anthropometric variables, sex and having diabetes. RESULTS: 30 subjects in the intervention group and 29 subjects in the control group completed the study. We found a significant reduction in the intervention group compared to the control group in FLI (-13.06 ± 10.03 vs. -2.90 ± 6.82;P < 0.001), HSI (-2.72 ± 2.59 vs. -0.81 ± 3.80;P = 0.02), WC (-6.02 ± 4.24 vs. -2.24 ± 4.28;P = 0.001), weight (-3.39 ± 2.53 vs. -1.51 ± 2.72;P = 0.008), BMI (-1.25 ± 0.93 vs. -0.56 ± 1.01;P = 0.008), DBP (-5.16 ± 3.92 vs. -1.50 ± 7.04;P = 0.01), SBP (-6.97 ± 8.21 vs. -1.36 ± 6.83;P = 0.006), TG (-18.50 ± 14.32 vs. 0.60 ± 23.81;P < 0.001), TC (-16.10 ± 17.94 vs. -5.07 ± 23.62;P = 0.04) and LDL-c (-13.50 ± 9.58 vs. -4.90 ± 18.28;P = 0.02). These results remained significant after adjusting for confounding factors, except for TC (P = 0.25). CONCLUSIONS: The DASH diet was more effective than the control diet in managing fatty liver and cardiovascular risk factors. TRIAL REGISTRATION: The trial was registered on 21 October 2022 at Iranian Registry of Clinical Trials (IRCT20180201038585N12, URL: https://irct.behdasht.gov.ir/trial/66161 ).

The relation of adherence to the DASH diet with migraine attack frequency and pain intensity in Iranian women: a cross-sectional study.

BACKGROUND: Migraine is a debilitating neurological discomfort characterized by moderate to severe unilateral headaches. Adherence to healthy dietary patterns like the DASH diet has been considered a complementary solution to migraine management. OBJECTIVE: In this study, we assessed the relation of adherence to the DASH diet with migraine attack frequency and pain intensity in women with migraine. METHODS: 285 female women with migraine were recruited in the current study. Migraine was diagnosed by a single neurologist based on the third edition of the International Classification of Headache Disorders (ICHD-III). Migraine attack frequency was determined based on the number of attacks per month. Pain intensity was assessed by the Visual Analogue Scale (VAS) and migraine index. Last year dietary intakes of women were collected using a semi-quantitative food frequency questionnaire (FFQ). RESULTS: Almost 91% of the women had migraine without aura. Most of the participants reported more than 15 attacks per month (40.7%) and pain intensity in the range of 8-10 in every attack (55.4%). Based on the ordinal regression, those in the first tertile of the DASH score had significantly higher odds for attack frequency (OR = 1.88; 95% CI: 1.11-3.18; P = .02) and migraine index score (OR = 1.69; 95% CI: 1.02-2.79; P = .04, respectively) than those in the third tertile. CONCLUSION: This study showed that a higher DASH score is associated with a lower migraine attack frequency and migraine index score in female sufferers.

Associations of adherence to the DASH diet and Mediterranean diet with maternal c-reactive protein levels during pregnancy.

BACKGROUND AND AIMS: Elevated C-reactive protein (CRP) during pregnancy, a marker of inflammation, is associated with adverse outcomes. Better understanding the relationship between CRP and modifiable factors, including diet, is essential to assist early pregnancy lifestyle interventions. The aim of this study was to assess the relationship between adherence to the Dietary Approaches to Stop Hypertension diet (DASH-diet) and the Mediterranean diet (MED-diet) during pregnancy with maternal plasma CRP in early and late pregnancy. METHODS AND RESULTS: Secondary analysis of the Creatine and Pregnancy Outcomes (CPO) study was undertaken. Women (n = 215) attending antenatal clinics through Monash Health, Melbourne were recruited at 10-20 weeks gestation. Medical history and blood samples were collected at 5 antenatal visits. Adapted DASH-diet and MED-diet scores were calculated from Food Frequency Questionnaires completed at early ([mean ± SD]) (15 ± 3 weeks) and late (36 ± 1 week) pregnancy. CRP was measured in maternal plasma samples collected at the same time points. Adjusted linear regression models assessed associations of early-pregnancy DASH and MED-diet scores with early and late pregnancy plasma CRP. There were no statistically significant changes in DASH-diet score from early (23.5 ± 4.8) to late (23.5 ± 5.2) pregnancy (p = 0.97) or MED-diet score from early (3.99 ± 1.6) to late pregnancy (4.08 ± 1.8) (p = 0.41). At early-pregnancy, there was an inverse relationship between DASH-diet scores and MED-diet scores with plasma CRP; (ß = -0.04 [95%CI = -0.07, -0.00], p = 0.044), (ß = -0.12 [95%CI = -0.21, -0.02], p = 0.023). CONCLUSION: Adherence to the DASH-diet and MED-diet during early pregnancy may be beneficial in reducing inflammation. Assessment of maternal dietary patterns may assist development of preventive strategies, including dietary modification, to optimise maternal cardiometabolic health in pregnancy.

Association of dietary patterns with diabetes-related comorbidities varies among diabetes endotypes.

BACKGROUND AND AIMS: Differences of dietary pattern adherence across the novel diabetes endotypes are unknown. This study assessed adherence to pre-specified dietary patterns and their associations with cardiovascular risk factors, kidney function, and neuropathy among diabetes endotypes. METHODS AND RESULTS: The cross-sectional analysis included 765 individuals with recent-onset (67 %) and prevalent diabetes (33 %) from the German Diabetes Study (GDS) allocated into severe autoimmune diabetes (SAID, 35 %), severe insulin-deficient diabetes (SIDD, 3 %), severe insulin-resistant diabetes (SIRD, 5 %), mild obesity-related diabetes (MOD, 28 %), and mild age-related diabetes (MARD, 29 %). Adherence to a Mediterranean diet score (MDS), Dietary Approaches to Stop Hypertension (DASH) score, overall plant-based diet (PDI), healthful (hPDI) and unhealthful plant-based diet index (uPDI) was derived from a food frequency questionnaire and associated with cardiovascular risk factors, kidney function, and neuropathy using multivariable linear regression analysis. Differences in dietary pattern adherence between endotypes were assessed using generalized mixed models. People with MARD showed the highest, those with SIDD and MOD the lowest adherence to the hPDI. Adherence to the MDS, DASH, overall PDI, and hPDI was inversely associated with high-sensitivity C-reactive protein (hsCRP) among people with MARD (ß (95%CI): -9.18 % (-15.61; -2.26); -13.61 % (-24.17; -1.58); -19.15 % (-34.28; -0.53); -16.10 % (-28.81; -1.12), respectively). Adherence to the PDIs was associated with LDL cholesterol among people with SAID, SIRD, and MOD. CONCLUSIONS: Minor differences in dietary pattern adherence (in particular for hPDI) and associations with markers of diabetes-related complications (e.g. hsCRP) were observed between endotypes. So far, evidence is insufficient to derive endotype-specific dietary recommendations. TRIAL REGISTRATION: Clinicaltrials.gov: NCT01055093.

Diet quality from mid to late life and its association with physical frailty in late life in a cohort of Chinese adults.

BACKGROUND: It is unclear if improving diet quality after midlife could reduce the risk of physical frailty at late life. We aimed to associate changes in diet quality after midlife with physical frailty at late life. METHODS: Diet quality in 12,580 participants from the Singapore Chinese Health Study was assessed with the Dietary Approaches to Stop Hypertension (DASH) scores at baseline (1993-1998; mean age 53 years) and follow-up 3 (2014-2016; mean age 73 years). Physical frailty was assessed using the modified Cardiovascular Health Study phenotype at follow-up 3. Multivariable logistic regressions examined associations between DASH scores and physical frailty. RESULTS: Comparing participants in extreme quartiles of DASH scores, the odds ratios (OR) [95% confidence interval (CI)] for physical frailty were 0.85 (0.73,0.99) at baseline and 0.49 (0.41, 0.58) at follow-up 3. Compared to participants with consistently low DASH scores, participants with consistently high scores (OR 0.74, 95% CI: 0.59, 0.94) and those with > 10% increase in scores (OR 0.78, 95% CI: 0.64, 0.95) had lower odds of frailty. Compared to those in the lowest DASH tertiles at both time-points, significantly lower odds of physical frailty were observed in those who were in the highest DASH tertiles at both time points [0.59 (0.48, 0.73)], and in those who improved their scores from the lowest [0.68 (0.51, 0.91)] or second tertile at baseline [0.61 (0.48, 0.76)] to the highest tertile at follow-up 3. CONCLUSIONS: Maintaining a high diet quality or a substantial improvement in diet quality after midlife could lower the risk of physical frailty at late life.

Concurrent validity study of QuickDASH with respect to DASH in patients with traumatic upper extremity amputation.

BACKGROUND: The Disability of the Arm, Shoulder and Hand Outcome Measure (DASH) is a validated patient-reported outcome measure (PROM) for many upper extremity musculoskeletal disorders. In patients with severe traumatic conditions, limited evidence exists regarding the equivalence between DASH and its shortened version, QuickDASH, which is more feasible in clinical practice. The rationale of this study was to analyze the concurrent validity of QuickDASH with respect to DASH in patients with traumatic upper extremity amputation. METHODS: This study is based on a consecutive cohort of traumatic upper extremity amputation patients treated with replantation or revision (completion) amputation at Tampere University Hospital between 2009 and 2019. We estimated the concurrent validity of QuickDASH with respect to DASH by correlation coefficients, mean score differences, Bland-Altman plots, and distribution density. Additionally, we assessed internal reliability with Cronbach's alpha coefficients and item-total correlations. RESULTS: We found a very strong linear correlation between DASH and QuickDASH scores (r = 0.97 [CI 95% 0.97-0.98], p < 0.001). The mean difference between DASH and QuickDASH was minor (MD = -1, SD 4 [CI95% from -1 to 0] p = 0.02). The mean sub-score for the activity domain was higher for QuickDASH than DASH (MD = -3 [CI95% from -4 to -3] p < 0.000) and lower for the symptom domain (MD = 7 [CI95% from 6 to 9] p < 0.000). The Bland and Altman plot showed good agreement between DASH and QuickDASH scores, but there was measurement error in QuickDASH with high scores (r = -0.20, [CI95% from -0.31 to -0.09], p = 0.001). CONCLUSION: QuickDASH demonstrates higher total scores than the full DASH and emphasizes rating of activity over symptoms. Still, on average the differences in total scores are likely less than the MCID of DASH, and consequently, this study shows that QuickDASH can be recommended instead of the full DASH when assessing a traumatic condition. TRIAL REGISTRATION: Retrospectively registered.

Associations between diet quality and dietary patterns and gestational diabetes mellitus in a low-risk cohort of pregnant women in Australia: a cross-sectional study.

INTRODUCTION: Evidence of associations between the Mediterranean Diet Score (MDS) and Dietary Approaches to Stop Hypertension (DASH) score and gestational diabetes mellitus (GDM) in pregnant women is limited. This study examined changes in MDS and DASH and dietary patterns in Australian pregnant women between early and late pregnancy and their associations with GDM. METHODS: The data from n = 284 participants were analysed. Diet quality indices and empirical dietary patterns were determined in early (15 ± 3 weeks gestation) and late pregnancy (35 ± 2 weeks gestation). Paired t-tests were used to examine changes in scores for diet quality indices and dietary patterns from early to late pregnancy. Logistic regression analysis was used to examine associations between GDM, diet quality indices and dietary patterns. RESULTS: Three major dietary patterns were identified at early pregnancy. The first and second dietary patterns included unhealthier and healthier food groups, respectively, and the third comprised mixed food groups. Although diet quality scores did not change over time, consumption of the first dietary pattern increased (p = 0.01), and consumption of the second dietary pattern decreased by late pregnancy in women without GDM (p < 0.001). CONCLUSION: No associations between DASH score, MDS and GDM were found; however an inverse association was observed between the first dietary pattern and GDM in late pregnancy (p = 0.023). Longitudinal studies are needed to examine diet quality and dietary patterns at early and late pregnancy to inform the development of tailored dietary advice for GDM.

Relation between the dash score and radiographic evaluation of the wrist in patients with wrist fracture.

Traditionally, the assessment of distal radius fracture outcomes has been based on radiological measurements and self-evaluation scores. However, there is uncertainty regarding how accurately these measurements reflect the patient's perception of their outcome. In this study, we examined the correlation between radiological measurements and patient-perceived outcomes using the Disabilities of the Arm, Shoulder, and Hand outcome (DASH) score. 140 individuals who had recovered from a distal radius fracture. and had been treated with DVR, Kapandji, percutaneous pinning or closed reduction were included in the study. The retrospective assessment included 78 females and 62 males, with a mean DASH score of 3.54 points.Except for the ulnar variance, the study found little to no significant association between the DASH score and the final radiological measurement.In summary, the DASH score did not always indicate that a superior radiological result translated into a better patient-perceived outcome.

Comparison of the low-calorie DASH diet and a low-calorie diet on serum TMAO concentrations and gut microbiota composition of adults with overweight/obesity: a randomized control trial.

This study compares two diets, Dietary Approaches to Stop Hypertension (DASH) and a Low-Calorie Diet on Trimethylamine N-oxide (TMAO) levels and gut microbiota. 120 obese adults were randomly allocated to these three groups: a low-calorie DASH diet, a Low-Calorie diet, or a control group for 12 weeks. Outcomes included plasma TMAO, lipopolysaccharides (LPS), and gut microbiota profiles. After the intervention, the low-calorie DASH diet group demonstrated a greater decrease in TMAO levels (-20 ± 8.1 vs. -10.63 ± 4.6 µM) and a significant decrease in LPS concentration (-19.76 ± 4.2 vs. -5.68 ± 2.3) compared to the low-calorie diet group. Furthermore, the low-calorie DASH diet showed a higher decrease in the Firmicutes and Bactericides (F/B) ratio, which influenced TMAO levels, compared to the Low-Calorie diet (p = 0.028). The current study found the low-calorie DASH diet improves TMAO and LPS in comparison to a Low-Calorie diet.
