This investigation seeks to scrutinize the relationships between body composition metrics and the clinical outcomes observed in patients with cholangiocarcinoma (CCA). A comprehensive exploration was conducted across three prominent online databases: Embase, PubMed, and the Cochrane Library. This endeavor spanned the entirety of each database up to the cutoff date of September 29, 2023. To evaluate the quality of the included studies, the Newcastle-Ottawa scale was employed. This comprehensive analysis included a total of 26 articles with a combined patient cohort of 4398 individuals. The results demonstrated that CCA patients with low skeletal muscle index (SMI) had significantly inferior OS (HR: 1.93, p < 0.001) and RFS (HR: 2.02, p < 0.001), as well as a higher incidence of postoperative complications (OR: 1.69, 95% CI: 1.20-2.38, p < 0.001) compared to those with high SMI. The presence of sarcopenia in CCA patients was significantly related to poorer OS (HR: 1.96, p < 0.001) and RFS (HR: 2.05, p < 0.001), and a higher rate of postoperative complications (OR: 1.39, p = 0.049) in comparison to those without sarcopenia. Moreover, lower psoas muscle index (PMI) and myosteatosis were associated with shorter OS (PMI, HR: 1.56, p < 0.001; myosteatosis, HR: 1.49, p = 0.001) and RFS (PMI, HR: 2.16, p < 0.001; myosteatosis, HR: 1.35, p = 0.023). Our findings highlight incorporating body composition screening into clinical practice can help develop treatment strategies and optimize perioperative care, potentially improving patient outcomes.

Background: Consumption of locally produced foods is generally perceived as being part of a healthy dietary pattern. Accordingly, in 2020, the provincial government of Québec (Canada) promoted the purchase of local foods for economic and health benefits. The present cross-sectional study aimed to document the association between the behavior of local food procurement and overall diet quality in a sample of adults from the province of Québec.

Methods: Data were collected in a sample of 834 adults (86.6% females) from the NutriQuébec project, a web-based longitudinal population study that aims to document the lifestyle and eating habits of adults in Québec, Canada. Dietary intakes were measured using a validated web-based 24-h recall tool and diet quality was assessed using the Healthy Eating Food Index (HEFI-2019), which measures adherence to the 2019-Canada's Food Guide recommendations on healthy food choices. Local food procurement behavior was measured using the Locavore-I-SF score, which assesses the frequency of short food supply chain use as well as the geographical origin of three locally produced foods.

Results: The Locavore-I-SF score was weakly correlated with the HEFI-2019 score (r = 0.08, p < 0.02). Positive correlations were observed for the Vegetables and fruits (r = 0.09, p = 0.005), Beverages (r = 0.08, p = 0.04) and Free sugars (r = 0.14, p < 0.001) components of the HEFI-2019. Associations between the Locavore-I-SF and the HEFI-2019 scores were found in specific subgroups of participants: males (r = 0.33, p < 0.001), participants aged between 50 and 70 years (r = 0.16, p = 0.003), participants with a greater education level (r = 0.13, p = 0.003) and higher income (r = 0.12, p = 0.02), non-vegetarian participants (r = 0.10, p = 0.008) and participants living in Census Metropolitan Areas (r = 0.11, p = 0.004).

Conclusion: These results suggest that the behavior of local food procurement is only weakly associated with better overall diet quality among a sample of adults from Québec, raising doubts on the relevance of promoting local food procurement as an effective public health measure for improving diet quality in Québec.

Background: Capsaicin is the main component of chili peppers and is believed to have antidiabetic effects. However, the association between spicy food consumption and the incidence of diabetes remains unclear.

Methods: A cohort of 20,490 Han residents aged 30-79 without diabetes at baseline were followed from enrollment to June 2, 2023. The consumption of spicy food was obtained through face-to-face surveys conducted during the baseline survey from October 2018 to February 2019. The definition of type 2 diabetes onset was based on the ICD-10 code of E11 in the diabetes case reporting system and death system; Additionally, self-reported diagnosis of diabetes by a physician in active follow-ups, or a fasting blood glucose level of ≥ 7 mmol/L or a glycated hemoglobin percentage of ≥ 6.5% found on-site during the resurvey. Both Cox proportional hazard regression and competing risk regression were used to calculate hazard ratios (HRs) and confidence intervals (CIs).

Results: During the follow-up period (53.5 ± 3.0 months), 182 individuals (1.1%) were newly diagnosed with T2D with an incidence rate of 246.2 per 100,000 person-years. Cox regression analyses revealed that spicy food consumers had a 34% reduced risk of developing type 2 diabetes (HR: 0.66, 95% CI: 0.48, 0.91) compared to non-consumers. The HRs (95% CIs) for participants consuming spicy food 3-5 days/week, 6-7 days/week, and with weak pungency were 0.45 (95% CI: 0.25, 0.81), 0.69 (0.49, 0.98), and 0.64 (0.46, 0.90), respectively. However, little significant protective effect was observed among those who consumed spicy food for 1-2 days/week, with moderate pungency, or with strong pungency (all P > 0.05).

Conclusions: Consuming spicy food may lower the risk of developing type 2 diabetes, particularly at a frequency of 3-5 days/week, and with weak pungency. Further multicenter prospective studies or interventional studies are needed to confirm these findings.

Background: Less is known whether the amino acid composition of dietary protein sources effects on long-term health outcomes. We aimed to evaluate the association between dietary amino acid composition and all-cause and cause-specific mortality.

Methods: This study used data from the Golestan Cohort Study, which was performed in the Golestan Province of Iran from January 2004 to June 2008. Mortality, which was the primary outcome, was ascertained through September 2022. The Cox proportional hazards regression models were used to determine the adjusted hazard ratios (HR) and 95% confidence intervals (CI) for mortality according to the quintiles of amino acid consumption, taking the third quintile as the reference.

Results: A total of 47,337 participants (27,293 [57.7%] women) with a mean (standard deviation) age of 51.9 (8.9) years were included. During a median follow-up of 15 years, 9,231 deaths were documented. Regarding essential amino acid intakes, the HRs of all-cause mortality were 1.16 (95% CI, 1.07-1.26) in the first quintile, compared with the reference group (P for non-linear trend < 0.001). Similarly, non-linear associations were observed between risk of all-cause mortality and intake of branched-chain, aromatic, sulfur-containing, or non-essential amino acids (P for non-linear trend < 0.001 for all comparisons), with higher HRs for participants in the first quintiles. There was an age interaction for the associations between dietary amino acids and mortality (P for interaction ˂0.05). While high amino acid diets were detrimental in middle-aged adults (< 65 years), increased hazards of mortality were observed among older adults (≥ 65 years) with low amino acid intake.

Conclusions: This study showed the non-linear trend between amino acids intake and risk of mortality in the middle-aged and older Iranian population. Overall, our findings suggest that diets lower in amino acids were associated with increased hazards of mortality, particularly among older adults.

Background: Iron is critical for maternal and fetal health; however, the effect of iron nutrition on fetal intrauterine growth remains unclear. This study aimed to investigate the associations of maternal iron nutrition during pregnancy with fetal intrauterine growth parameters among the Chinese population.

Methods: This retrospective birth cohort study included 482 pregnant women. Maternal information was collected by standard questionnaires. Maternal concentrations of serum ferritin and hemoglobin were detected. Fetal ultrasound examinations in the second and third trimesters were conducted. Quantile regression or linear regression models were applied to assess the associations.

Results: Participants took iron supplementation in early, mid, and late pregnancy accounted for 19.1%, 40.3%, and 37.8%, respectively. Iron supplementation in the first and second trimesters and total iron intake in pregnancy were positively associated with fetal intrauterine growth parameters at some percentiles. Compared with those without iron supplementation in the second trimester, women with iron supplementation in the second trimester had 0.37 (95%CI = 0.24-0.49), 0.37 (95%CI = 0.26-0.48), 0.15 (95%CI = 0.04-0.26), and 0.52 (95%CI = 0.42-0.61) higher z-scores in fetal biparietal diameter, femur length, abdominal circumference, and estimated fetal weight at the 50th percentile in the second trimester, respectively. Maternal serum ferritin and hemoglobin concentrations in the first and second trimesters were positively correlated with several fetal growth parameters.

Conclusions: Fetal intrauterine growth may benefit from maternal iron nutrition in the first and second trimesters.

Background: Sulfur microbial diet (SMD) is a dietary pattern closely related to the intestinal load of sulfur-metabolizing microbes in humans. Diet and microbes may play an important role in the carcinogenesis of esophagus. However, epidemiological studies on SMD and esophageal cancer (EC) risk are scarce. Here, we evaluated this association based on a large American cohort.

Methods: In the cohort of the Prostate, Lung, Colorectal, and Ovarian (PLCO) Cancer Screening Trial, a SMD score was calculated to evaluate participants' compliance of SMD pattern, with higher scores presenting greater adherence. Cox hazards regression model was used to explore the association between the SMD score and the incidence of EC, esophageal squamous cell carcinoma (ESCC), and esophageal adenocarcinoma (EA). Subgroup analyses were conducted to figure out potential modifiers interacting with SMD on EC. Sensitivity analyses were used to testify the robustness of our main result.

Results: Among 101,752 participants, 154 EC cases, consisted of 41 ESCC cases and 97 EA cases, were identified with mean follow-up of 8.9 years. In the fully adjusted model, the highest versus the lowest quartiles of the SMD score were found to be associated with an increased risk of EC and ESCC (EC: HR_{Q4 vs. Q1}: 1.64; 95% CI: 1.05, 2.56; P = 0.016 for trend; ESCC: HR_{Q4 vs. Q1}: 2.37; 95% CI: 1.02, 5.47; P = 0.031 for trend), while not significantly associated with increases risk of EA (HR_{Q4 vs. Q1}: 1.41; P = 0.144 for trend). The main result remained through a series of sensitivity analyses. Subgroup analyses showed a stronger association between SMD and EC in participants with no regular consumption of aspirin (HR_{Q4 vs. Q1}: 1.90; 95% CI: 1.04, 3.47) than in those using aspirin regularly (HR_{Q4 vs. Q1}: 1.37; 95% CI: 0.71, 2.66) (P = 0.008 for interaction).

Conclusion: Adherence to the SMD pattern may be associated with increased risks of EC and ESCC, particularly for EC in individuals who do not regularly consume aspirin.

Background: Higher consumption of sugary beverages (SB) has been associated with type 2 diabetes (T2D), but whether these associations are modified by physical activity remains unclear. This study aimed to examine the associations of SB intake, including sugar-sweetened beverages (SSB), artificially sweetened beverages (ASB), and natural juices (NJ) with the risk of incident T2D, and the potential role of physical activity.

Methods: We included 153,862 diabetes-free participants in the UK Biobank who completed both the International Physical Activity Questionnaire at recruitment (2006-2010) and at least one 24-h dietary recall questionnaire in 2009-2012. We assessed the associations of each SB with the risk of incident T2D using Cox proportional hazard models, and explored the interactions between each SB and physical activity.

Results: During a median follow-up of 11.8 years, 6631 participants developed incident T2D. Participants consuming more SSB and ASB (comparing > 2 to 0 unit/d) had a higher hazard of T2D (hazard ratio [HR]: 1.17, 95% confidence interval [CI]: 1.05-1.31 for SSB; 1.54, 1.37-1.74 for ASB), while medium intake of NJ showed an inverse association (HR_{> 0-1 vs. 0 unit/d}: 0.87, 95% CI: 0.82-0.92; HR_{> 1-2 vs. 0 unit/d}: 0.88, 95% CI: 0.81-0.97) with incident T2D. No significant interactions between physical activity and SSB/ASB were found (P-interaction=0.204 for SSB, 0.926 for ASB), but the protective association of medium NJ intake with T2D was stronger among participants with higher level of physical activity (P-interaction = 0.043).

Conclusions: Higher intake of SSB and ASB was related to higher risks of T2D. Medium NJ intake was associated with a lower risk of T2D, particularly among individuals with higher physical activity level. These findings emphasized the importance of healthy beverage intake and adequate physical activity in diabetes prevention.

Background: The initiation time and formula for supplemental parenteral nutrition after surgery require optimization, especially in older patients undergoing major gastrointestinal surgery. This study aimed to assess the effect of early supplementation with a branched-chain amino acid (BCAA)-enriched formula (BAF) on short-term postoperative outcomes in older patients undergoing gastric surgery.

Methods: This single-center, prospective, double-blinded, randomized clinical trial was conducted from March 10, 2020, to September 15, 2022. Patients aged 65-80 years with gastric cancer scheduled for curative resection were assessed for eligibility and randomly allocated to a high-proportion BCAA (HBCAA) (early supplementation with the BAF) or control (routine nutrition) group. The primary outcome was the standardized length of hospital stay (LOS).

Results: A total of 150 patients were randomized. Thirteen patients were excluded due to the resection of other organs, presence of metastasis, or withdrawal of consent. Finally, we included 70 and 67 patients in the HBCAA and control groups, respectively (mean age: 70.5 ± 4.2 years; 96 men [70.1%]). The standardized LOS was significantly shorter in the treatment group than in the control group (median [interquartile range]: 8.0 [7.8, 8.0] vs. 8.5 [8.0, 9.0] days; mean difference, 0.38; 95% confidence interval [CI], 0.02-0.74 days; P < .001). Patients in the HBCAA group showed better gastrointestinal function with faster defecation (4.0 [3.6, 5.0] vs. 5.0 [4.0, 5.5] days; mean difference, 0.6 days; 95% CI, 0.26-0.94 days; P < .001) and semi-liquid diet initiation (8.0 [7.5, 8.0] vs. 8.0 [8.0, 8.8] days; mean difference, 0.36 days; 95% CI, 0.03-0.7 days; P < .001) and had lesser weight loss at postoperative day 5 than those in the control group did (3.5 [2.7, 6.5] vs. 4.9 [3.3, 7.6]%; mean difference, 1.23%; 95% CI, 0.27-2.19%; P = .011).

Conclusions: In this randomized clinical trial, compared with routine nutrition, early supplementation with a BAF was associated with a shorter standardized LOS in older patients undergoing gastric surgery, suggesting that it may be a favorable strategy for patients with a poor tolerance to external nutrition who are undergoing major surgery.

Background: Oral sensory hypersensitivity has been linked with fussy eating predominantly in non-typically developing children. We hypothesized that child 'Oral' (touch, smell and taste in the mouth) and 'Social-Emotional' (response to social expectations) sensory processing are associated with child appetitive traits in typically developing preteen children. Additionally, we explored relationships between maternal sensory profiles and their offspring's sensory profile.

Methods: This is secondary analysis of 130 mother-child dyads from the 9-11-year-old follow-up of the ROLO longitudinal birth cohort study. The Dunn Sensory Profile (Adolescent/Adult) and the Dunn Child Sensory Profile 2 were used to assess maternal and child sensory profiles, respectively. The Children's Eating Behaviour Questionnaire was used to assess child appetitive traits. Multiple linear regression examined associations between 'Oral' and 'Social-Emotional' segments of the child sensory profile and child appetitive traits. Associations between maternal and child sensory profiles were examined using sensory profile quadrants (Dunn's sensory processing framework). These refer to four distinct patterns of sensory processing that indicate how an individual responds to sensory input.

Results: In total, 130 mother-child dyads were included. In adjusted analysis child 'Oral' sensory processing was associated with higher mean scores in the appetitive traits 'Desire to Drink' (B = 0.044, 95% CI = 0.025,0.062) and 'Food Fussiness' (B = 0.080, 95% CI = 0.059,0.101) and with lower mean scores in 'Enjoyment of Food' (B=-0.038, 95% CI -0.055,-0.022). Child 'Social-Emotional' responses were associated with higher mean scores in 'Desire to Drink' and 'Food Fussiness'. Higher scores in the maternal sensory profile quadrants of 'Sensitivity', 'Avoiding' and 'Registration' were positively associated with higher scores in the corresponding child sensory profile quadrants.

Conclusion: Our findings suggest that in typically developing children presenting with fussy eating, oral sensory hypersensitivity and higher scores in social-emotional responses to sensory processing may be an underlying determinant. The relationship observed between 'Oral' and 'Social-Emotional' sensory processing segments and 'Desire to Drink' requires further research to ascertain the type of drinks being consumed and how this impacts appetite. Further research is also required to explore the influence of maternal sensory profile on their offsprings response to sensory input.
