Abstract 4141442: The Feasibility and Adherence of Online Intensive Cardiac Rehabilitation Program for Coronary Artery Disease-A pilot Study

Introduction/Background: Remote cardiac rehabilitation is becoming more popular, but most are exercise-based cardiac rehabilitation programs, and online intensive cardiac rehabilitation (ICR) programs that include not only exercise training but also dietary guidance, stress management, and group support have not been widespread. Research Questions/Hypothesis: Whether high adherence and improvement of CAD risk factors demonstrated for the online ICR program. Goals/Aims: We assessed the program adherence by participation rate as the primary endpoint and physical findings, typical CAD risks and nutritional indices as the secondary endpoint. Methods/Approach: The J-ICR program provides online instruction using Zoom (San Jose, CA: Zoom Video Communications Inc.). The program consisted of four parts: aerobic exercise training, dietary education for the Japan diet, stress management training through mindfulness, and group support (10 participants per group) for 3 hours per session, once a week for 12 weeks (36 hours total). Twenty-two patients were enrolled and adherence to the program was examined. Changes in CAD risk factors were also analyzed. Results/Data: After excluding 3 patients who withdrew consent before the program, the current study population consisted of 19 male participants. The mean age was 66 years old, 95% had hypertension, 37% had diabetes mellites and all had hyperlipidemia. Eight patients had myocardial infarction and 15 cases of angina pectoris. The average participation rate of the program was 90.2% and there was no drop out during the program. As the secondary endpoint, body weight （69.2kg vs. 68.2kg; p=0.02), systolic and diastolic blood pressure (126.8mmHg vs. 121.4mmHg; p<0.01 and 79.5mmHg vs. 77.6mmHg; p=0.18), LDL cholesterol (78.9mg/dl vs 77.6mg/dl; p=0.68), HbA1c (6.3% vs. 6.4%; p=0.39), and amount of sodium intake (9.5 g/day vs. 9.5g/day; p=0.68) and total energy intake (2,137kcal/day vs. 2,076kcal/day; p=0.25). Conclusion: The J-ICR program is feasible and may yield improvements in CAD risk factors such as body weight and systolic blood pressure. Since this is a pilot study to explore the feasibility of the online J-ICR, its secondary prevention effect should be verified with appropriately powered randomized trials at multiple centers.

Abstract 4136294: Carbohydrate intakes and cardiovascular disease risk factors in South Asians: Results from 56,024 participants in Bangladesh, India, Pakistan, and Sri Lanka

Background: Evidence on effects of carbohydrate intake with cardiovascular disease risk factors is inconsistent and has limited generalizability to diverse populations such as South Asians, whose carbohydrate intakes are typically high. Aims: We examined the association of the quantity and types of carbohydrate intake with two risk factors for major cardiovascular events– hypertension (HT) and hypercholesterolemia (HC). Methods: We analyzed cross-sectional data from participants aged ≥18 years in the South Asia Biobank in Bangladesh, India, Pakistan, and Sri Lanka. Using dietary data assessed with interviewer-led 24h diet recalls, we calculated intakes of total and subtypes of carbohydrates and several indices of carbohydrate quality. Primary outcomes were HT and HC, defined by medication use, doctor diagnosis, blood pressure and blood lipid levels. With mixed effects Poisson regression, HT and HC was regressed on quantiles of carbohydrate intakes by country to estimate prevalence ratios (PR) and 95% confidence intervals (CI), followed by meta-analysis pooling country-specific estimates. We examined interactions by diabetes status and adiposity. Results: Of 56,024 adults, 36.6% had HT, 16.1% had HC. In pooled multivariable analyses comparing extreme quantiles, total carbohydrate intake was not associated with HT or HC prevalence. Fructose, free sugar and free sugar-to-fiber ratio were associated with higher prevalence of HT (PRs Q5vsQ1 : 1.03-1.15). Higher intakes of cereal fiber (PR Q4vsQ1 : 0.96, 95% CI: 0.95-0.98) and legume fiber (PR Q4vsQ1 : 0.98, 95% CI: 0.97-0.98) were associated with lower prevalence of HT and higher cereal fiber intake with lower HC prevalence (PR Q5vsQ1 : 0.80, 95% CI: 0.75-0.85). Diabetes and adiposity were observed as effect-modifiers (p<0.001). There were null associations in adults with diabetes but in non-diabetic adults, free sugar intake was related positively with HT (PR Q5vsQ1 : 1.07, 95% CI: 1.05-1.09) while fiber intake was inversely related (PR Q5vsQ1 : 0.98, 0.95-0.97). Starch, sugar and free sugar intake were associated positively with HT prevalence in adults with high body fat (≥20% for men; ≥30% for women) and visceral fat (≥10%) levels (PRs Q5vsQ1 : 1.03-1.20); associations were null for low body and visceral fat levels. Associations varied by country (between-country heterogeneity I 2 >60%). Conclusion: Associations of dietary carbohydrates with HT and HC depended on the quality and type of intake in South Asians.

Vegetable Salad Improves Lipid and Glucose Metabolism and Enhances Absorption of Specific Nutrients in Vegetables

Vegetables are low in energy and rich in vitamins, minerals, and dietary fiber; various health benefits associated with their intake have been reported. Salads are one of the most convenient ways to consume vegetables and can be made simply by pouring mayonnaise, dressing, olive oil, or other condiments over a selection of vegetables. There are also many reports on the ways in which vegetable intake can improve health. However, there is no comprehensive review summarizing the health functions of vegetables when consumed as a salad. The effects of vegetable salads on amounts of vegetable intake, lifestyle-related diseases, and the absorption of specific nutrients through mayonnaise, as well as the effects of the order in which vegetable salad and carbohydrates are consumed, have been reported. In this review, the health functions of vegetable salad consumption are reported.

Non-fermented and fermented milk intake in relation to risk of ischemic heart disease and to circulating cardiometabolic proteins in swedish women and men: Two prospective longitudinal cohort studies with 100,775 participants

BackgroundThe effect of milk on the risk of ischemic heart disease (IHD) and acute myocardial infarction (MI) is unclear. We aimed to examine the association between non-fermented and fermented milk consumption on these endpoints and investigate the relationship between milk intake and cardiometabolic-related proteins in plasma.MethodsOur study is based on two Swedish prospective cohort studies that included 59,998 women and 40,777 men without IHD or cancer at baseline who provided repeated measures of diet and lifestyle factors and plasma proteomics data in two subcohorts. Through registry linkage, 17,896 cases with IHD were documented during up to 33 years of follow-up, including 10,714 with MI. We used time-updated multivariable Cox regression analysis to examine non-fermented or fermented milk intake with time to IHD or MI. Using high-throughput multiplex immunoassays, 276 cardiometabolic plasma proteins were measured in two subcohorts. We applied multivariable-adjusted regression models using a discovery-replication design to examine protein associations with increasing consumption of non-fermented or fermented milk.ResultsThe results for non-fermented milk differed by sex (p-value for interaction = 0.01). In women, we found a pattern of successively greater risk of IHD and MI at non-fermented milk intake levels higher than 1.5 glasses/day. Compared with an intake of 0.5 glass/day (100 mL/day), non-fermented milk intake of 2 glasses/day in women conferred a multivariable-adjusted hazard ratio (HR) of 1.05 (95% CI 1.01–1.08) for IHD, an intake of 3 glasses/day an HR of 1.12 (95% CI 1.06–1.19), and an intake of 4 glasses/day an HR of 1.21 (95% CI 1.10–1.32). Findings were similar for whole, medium-fat, and low-fat milk. We did not detect higher risks of IHD with increasing milk intakes in men. Fermented milk intake was unrelated to the risk of IHD or MI in either sex. Increasing non-fermented milk intake in women was robustly associated with a higher concentration of plasma ACE2 and a lower concentration of FGF21.ConclusionsWe show a positive association between high amounts of non-fermented milk intake and IHD in women but not men. We suggest metabolic pathways related to ACE2 and FGF21 potentially underlie the association.Graphical abstractOur analysis of two large cohort studies involving 100,775 participants and 17,896 clinically confirmed IHD events supports a dose–response positive association between non-fermented milk intake higher than 300 mL/day with higher rates of IHD (and acute MI specifically) in women, but not in men. The higher risk of IHD with high milk intake in women was evident, irrespective of the fat content of the milk. Fermented milk intake was unrelated to the risk of IHD in both women and men. Non-fermented milk intake was associated in different directions with circulating levels of ACE2 and FGF21 in women—two essential cardiometabolic proteins, also related to IHD in women in our study.

Quantitative relationship between free sugars intake and early childhood caries among preschoolers in Sri Lanka

IntroductionBefore implementing the WHO sugar recommendations, more studies are needed concerning its application to given contexts. ObjectiveTo identify free sugars intake levels associated with a minimum caries risk in primary dentition MethodsUsing probability proportionate to size technique and cluster sampling, 813 children aged 4-5-years were selected from preschools in the Colombo district, Sri Lanka. A 67-item quantitative food frequency questionnaire was developed and validated to evaluate free sugars intake. Dental caries was assessed clinically using dmft index. For the selection of cut-off values for free sugars intake levels, ROC curves were used. ResultsThe median (IQR) amount of free sugars intake was 57.9 (33.2 -95.8) g/day or 21.1% (12.5%-35.9%) of total energy requirement, with a frequency of 4.0 (2.7-6.1) times/day. Dental caries prevalence was 42.9% (n=349). Among all possible risk factors, free sugars intake as a percentage of total energy requirement (p<0.001) and frequency of free sugars intake (p<0.001) were significantly associated with the presence of dental caries. The percentage of free sugars that discriminates against a possible highest number of children with dental caries (99%) was determined as 4%, of the total energy requirement of a child, which is approximately 12g/day (3 level teaspoons/day). Sugar intake once a day has a 97% sensitivity in identifying children with dental caries. These cut-off values do not differ among the group who brush twice a day with fluoridated toothpaste. ConclusionFor optimal caries prevention, children's free sugar intake to less than 5% of their total energy intake or consume less frequently than once daily.

Mathematical Modeling of Gas-phase Mass Transfer in Hydrous Materials for a Total Heat Exchange Ventilator

Total heat exchange ventilation systems are effective in achieving energy savings by reducing the ventilation load in buildings, while maintaining a certain amount of fresh outdoor air intake. As the system's elemental materials exchange both latent and sensible heat, hydrophilic chemical compounds may be exchanged simultaneously. Proper control of the exchange of hazardous chemicals and pollutants via these heat exchange elements is an important issue in the development of total heat exchange ventilation systems. In this respect, the development of a numerical model that facilitates repeated sensitivity analysis is important in the development of a new total heat exchanger that has high heat exchange efficiency and suppresses the exchange of polluting chemicals. This study proposes new hygrothermal and chemical compound transfer models for paper-based hydrous materials, which are the main components of total heat exchangers in indoor ventilation systems. Through a series of numerical analyses and experimental measurements, the prediction accuracy of the mathematical model was compared with experimental results for the gas transfer rate in hydrous materials and a building-sized total heat exchanger. The results demonstrated that an increase in water content in hydrous material has a significant impact on the permeability of water-soluble gases, with NH3 and HCHO permeability coefficients increasing by factors of 250 and 20 respectively. Conversely, for low-solubility gases such as CO2, the permeability coefficient only slightly increased at low humidity and remained largely unaffected thereafter. These findings contribute to the advancement of more efficient and safer total heat exchange ventilation systems.

Association between dietary supplements and frailty by sex: a cross-sectional study in South Korea

Abstract Background Evidence regarding the benefits of dietary supplements against frailty is lacking. Therefore, we aimed to examine the association between the use of dietary supplements and frailty. The analyses were stratified by sex to consider the sexual dimorphism in frailty. Methods This study used national, cross-sectional survey data from South Korea, namely the Korea National Health and Nutrition Examination Survey (KNHANES, 2018-2020). Adults aged 50 years were included. Data for up to four supplements were collected for each participant. A 46-item frailty index was constructed to assess frailty. All percentages (%) were weighted to represent the national population. The association between the use of dietary supplements and frailty was investigated using a linear regression analysis with socioeconomic/lifestyle factors and the amount of nutrient intake from diet included as covariates. Results Of the included 27,384 older adults, 57.28% were women. The proportion of supplement users was significantly higher in women (64.31% vs. 77.71%, p &amp;lt; 0.001). Any supplement use was negatively associated with frailty (B = -0.015, p &amp;lt; 0.001), and the association was more significant in women (Any supplement use * women: B = -0.012, p = 0.002). From the multivariable regression analysis stratified by sex, the use of red ginseng (men: B = -0.019, women: B = -0.015) and calcium (B = -0.027, women: B = -0.012) were negatively associated with frailty in both sexes while the statistical significance for vitamin C was found only in men (B = -0.020) (all p &amp;lt; 0.05). Conclusions Our findings demonstrated a significant negative association between the use of dietary supplements and frailty. The associations varied by type of supplements and by sex. The findings should be validated using prospective data. Key messages • Red ginseng and calcium supplements were negatively associated with frailty in both sexes. • We assessed frailty using frailty index which highlights the potential role of dietary supplements beyond the context of physical or musculoskeletal function.

The Relationship of Dietary Pattern and Physical Activity on Cholesterol Level in Young Adults

High blood cholesterol levels are a serious problem because they are one of the risk factors for degenerative diseases such as cardiovascular. Research data shows that in Ambon City, 32.49% of the population has the habit of consuming fatty/cholesterol/fried foods ≥1 time per day. The purpose of this study was to determine the relationship between dietary habit and physical activity with blood cholesterol levels. The type of research used was quantitative, sampling technique used was convenience sampling for 30 people. The independent variables in this study were dietary intake (amount, frequency, and type) measured using a semi-quantitative FFQ and physical activity measured using the IPAQ questionnaire and dependent variable was cholesterol level. The limiting variable was blood cholesterol levels taken through skin pricks. The results showed no relationship between diet and physical activity and blood cholesterol levels.

Early Life Energy Balance: The Development of Infant Energy Expenditure and Intake in the Context of Obesity.

This review aims to provide a summary of the current knowledge on measurement tools and most recent evidence for prenatal and postnatal modulators of energy balance in young infants. The prevention of pediatric obesity depends upon curating the perfect imbalance of energy intake to energy expenditure, taking into consideration the energy needs for healthy growth. We summarize the recent evidence for the programming of fetal and infant metabolism influenced by maternal preconception health, prenatal metabolic milieu, and physical activity behaviors. In the early postnatal environment, caregiver feeding behaviors shape the extent of energy imbalance through dictating quantity and modality of infant energy intake. There are biological and behavioral contributors to improper infant energy imbalance. Furthermore, caregiver and clinician education on overfeeding and clinical tools to prescribe and monitor infant overgrowth are absent. Ultimately, the lack of high-quality and modern research of infant energy expenditure underpins the lack of advancement in clinical guidelines and the needed prevention of pediatric obesity.

Bioactive compounds delivery and bioavailability in structured edible oils systems.

The health benefits of bioactive compounds are dependent on the amount of intake as well as on the amount of these compounds that become bioavailable and bioaccessible. Various systems have been developed to deliver and increase the bioaccessibility of bioactive compounds. This review explores the impact of gelled (oleogels, bigels, emulgels, emulsions, hydrogels, and hydrogel beads), micro-(gels, particles, spheres, capsules, emulsions, and solid lipid microparticles) and nanoencapsulated systems (nanoparticles, solid lipid nanoparticles, nanostructured lipid carriers, nanoemulsions, liposomes, and nanoliposomes) on the digestibility and bioavailability of lipophilic and hydrophilic bioactives. Structurant molecules, the oil type, antioxidants, emulsifiers, and coatings in delivery systems with promising potential in food applications are critically discussed. The release and bio-accessibility of bioactive compounds in gelled systems are influenced by various factors, such as the type and concentration of gelators, the gelator-to-oil ratio, the type of antioxidant, the network of the system, and its hydrophobicity. The stability, bioaccessibility, and controlled release of bioactives were improved in structured emulsions. Several variables, including wall material, oil/water ratios, encapsulation process, and pH conditions, can affect the bioactives release in microencapsulated systems. Factors like coating type and core-to-wall ratio impact the stability and release of core components. The encapsulating material, the encapsulation technology, and the nature of the nanomaterials all have an impact on the bioaccessibility of nanoencapsulated systems. Nanoliposomes provide enhanced stability and absorption. In general, all encapsulated systems have shown great potential in improving the distribution and availability of bioactive compounds.

The Relationship of the Level of Nutritional Knowledge and Fat Intake to Cholesterol Levels in PT Employees Bolaang Mongondow District Tourism Management

Background: The quality of human resources is the main factor required for the successful implementation of business in the company. Labour productivity has a very important role in the development of human resources in the company. Empirical evidence shows that the quality of human resources can be determined by good nutritional status, and good nutritional status is determined by nutritional knowledge, the amount of food intake consumed and a person's physical activity. Objective: The aim of this research was to determine the relationship between the level of nutritional knowledge and cholesterol levels and fat intake among employees of PT Tata Wisata JRBM Bakan, Bolaang Mongondow Regency. Study Design: This type of research is analytical with a cross sectional approach. Place and Duration of Study: The research was conducted at PT. Bakan Village Tourism Arrangement, Bolaang Mongondow Regency in November 2023. Methods: The population in this study were all employees of PT. Tata Wisata – JRBM Bakan Regency. Bolaang Mongondow aged 20-49 years, a total of 49 people. The samples in this study were 33 samples which were determined using the Slovin formula.Data collection was obtained from measuring cholesterol levels, fat intake using a 24-hour food recall form and nutritional knowledge by giving questionnaires to the sample. Results: The results of research and data analysis of a large sample with high category nutritional knowledge were 20 samples (60.6%). The fat intake of most samples was in the category above requirements for 18 samples (33%). Most of the cholesterol levels were at the threshold of high cholesterol levels in 14 samples (42.4%) and high cholesterol in 4 samples (12.1%). There is no relationship between nutritional knowledge and fat intake with a p value of (0.629). There is a relationship between fat intake and cholesterol levels with a p value (0.000). There is no relationship between nutritional knowledge and cholesterol levels with a p value of (0.882). From this research it can be concluded that of the 3 variables tested, namely nutritional knowledge, cholesterol levels and fat intake, only fat intake and cholesterol levels have a relationship.

Changes in the frequency and amount of alcohol intake before and during the COVID-19 pandemic.

Concerns have been raised regarding the impact of the COVID-19 pandemic on alcohol consumption patterns, which can have implications for public health. In this descriptive study, we aimed to show the change of the frequency and amount of alcohol consumption in Japan before and during the COVID-19 pandemic periods. We analysed data from annual health-check-ups among Japanese workers from April 2018 to March 2021. Changes in the frequency (daily, occasionally, rarely/never) and amount per one-time (four categories by Japanese alcohol unit) of alcohol consumed among 331,200 participants were summarised by sex as 1-year changes in the periods before (FY2018 to FY2019) and during (FY2019 to FY2020) the COVID-19 pandemic. Among daily drinkers and rarely/never drinkers, overall, 1-year changes in the frequency of alcohol consumption during the pandemic were mostly consistent compared with changes before the pandemic, for both sexes. The number of occasional drinkers who drank less frequently a year later increased during the pandemic compared with before the pandemic (from 9.6% to 11.6% among men and 12.9% to 16.5% among women); however, occasional drinkers who drank more frequently showed a small increase. Collectively, both men and women showed a slight decrease in both the frequency and amount of alcohol consumption during the pandemic among occasional drinkers. No major shifts in alcohol consumption habits occurred during the pandemic in our study population. Occasional drinkers tended to drink less during the pandemic, suggesting that initial concerns about increased alcohol consumption owing to the pandemic were unfounded.

Association of omega-3 polyunsaturated fatty acids intake and cognitive function in middle-aged and older adults

ABSTRACT Objective Omega-3 polyunsaturated fatty acids (PUFAs) play a crucial role in maintaining and improving cognitive function and brain health. The aim of this study was to assess the association between omega-3 PUFA intake and cognitive function in middle-aged and older adults in Saudi Arabia. Methods Cognitive function was assessed using the Montreal Cognitive Assessment (MoCA). The frequency and quantity of omega-3 PUFA intake were assessed using an omega-3 food frequency questionnaire. Results A total of 175 participants were recruited for this study. Participants in the lowest omega-3 PUFA tertile group scored significantly lower in the visuospatial/executive and attention cognitive domains (p < 0.05). After adjusting for confounders, the higher intake of alpha-linolenic acid (ALA) was significantly associated with higher scores in the visuospatial/executive domain (p = 0.02) and the higher intake of docosahexaenoic acid (DHA) was significantly associated with higher scores in the attention domain (p = 0.04). The participants who did not consume walnuts showed a significant lower MoCA score than those who did (p = 0.005). No significant differences were found with other omega-3 PUFA sources. Conclusion Higher intake of omega-3 PUFAs was positively associated with visuospatial/executive and attention cognitive functions in middle-aged and older adults.

WATER INTAKE PATTERNS

The current research titled, “Water Intake Patterns” is a comparative study aged 16-25 between girls and boys pertaining to overall effects due to inadequate quantity of water intake

Evaluation of TRPM2 Channel-Mediated Autophagic Signaling Pathway in Hippocampus and Cortex Tissues of Rat Offspring Following Prenatal Exposure to Elevated Alcohol Levels.

Fetal alcohol syndrome (FAS) can occur because of high amount of alcohol intake during pregnancy and is characterized by both physical and neurological problems. Children diagnosed with FAS have difficulties in learning, memory, and coordination. Hippocampus has a major role in memory and learning. We aimed to determine whether alcohol exposure during pregnancy had any effect on offspring by evaluating learning ability as well as oxidative stress and autophagy in the hippocampus and cortex tissues of litters. Attention was also paid to sex differences. To do so, TRPM2, Beclin1, p62, LC3B, IBA1, parvalbumin, GAD65, and mGluR5 expression levels were evaluated by immunohistochemistry. Lactate dehydrogenase (LDH), and malondialdehyde (MDA) levels, as well as total oxidant (TOS) and total antioxidant (TAS) status were determined by ELISA. Learning experiments were evaluated by the Morris water maze (MWM) test. Our findings demonstrated that IBA1, LC3B, GAD65, and mGluR5 expression levels were higher in female rats of the chronic alcohol exposure (CAE) model. Our IHC results revealed that TRPM2 expression levels were significantly increased in both males and females in the CAE group. Likewise, TAS was lower, and TOS was higher in CAE animals. Moreover, MWM outcomes supported a learning deficiency in CAE litters compared to controls and indicated that female offspring outperformed males in learning experiments. Therefore, our results revealed the detrimental effects of alcohol exposure during pregnancy on autophagy signaling in the hippocampus and cortex tissue of litters, which could affect the learning ability of animals.

Real meat shows good performance in maintaining colonic barrier function at a recommended amount of intake in mice

AbstractThis study aimed to investigate the effects and underlying mechanisms of real meat and plant‐based meat analogs on intestinal barrier function. Methods including PacBio sequencing, HPLC, histological observation, western blotting, and RT‐qPCR were jointly applied. The results indicated that the 20‐day intake of real meat and plant‐based meat analogs did not induce pathological changes in the colon of mice. However, when the feeding period was extended to 68 days, inflammatory infiltration was observed in the colon tissue of mice fed plant‐based meat analogs. In contrast, the intake of real meat for 68 days performed better in maintaining colonic barrier function by reducing cell apoptosis, increasing the number of goblet cells and mucin secretion, and upregulating the expression of tight junction proteins. High‐throughput sequencing revealed that the intake of real meat significantly altered the composition of the gut microbiota, reducing pro‐inflammatory bacteria (such as Bacteroides, Desulfovibrio, or Colidextribacter) or pathogenic bacteria (such as Mucispirillum and Helicobacter) while increasing beneficial bacteria (such as Lactobacillus, Bifidobacterium, or Roseburia). Additionally, the consumption of real meat markedly decreased protein fermentation in the colon, leading to lower levels of cadaverine, putrescine, and spermine. These changes associated with real meat consumption reduced the activation of the pro‐inflammatory pathway (lipopolysaccharide/Toll‐like receptor 4/nuclear factor kappa B), ultimately maintaining colonic homeostasis in mice. Collectively, the findings suggest that the proper intake of real meat is more beneficial for colon health in mice compared to plant‐based meat analogs.

Longitudinal comparison of the relationship of energy intake with body composition and physical performance in elite female basketball and volleyball players

Abstract Purpose To maximise sporting success, disciplines such as basketball and volleyball need to improve their methods of analysing the sporting performance and fitness of their athletes. Although energy intake quantities have been established at a theoretical level for women to perform at a sporting level, it has been found that these energy intake levels are not met or followed and that, despite this, the performance of female players is not diminished. Thus, the purpose of this research study was to describe and compare the anthropometric characteristics of these two disciplines and to identify the differences in actual and theoretical energy intake, as well as to observe physical performance in both disciplines. Methods Anthropometric data, continuous quantitative data, training time and characteristics, and energy intake data were collected. Performance tests included upper and lower body strength, speed, agility, and endurance tests. Dietary monitoring showed lower intakes of total energy, carbohydrate and protein than theoretically recommended. However, the athletes experienced overall improvements in performance and body composition. Results The mean total energy intake was 20.2 ± 4.3 kcal·kg−1·day−1. The minimum individual mean intake was 9.8 kcal·kg−1·day−1 and the maximum was 25.95 kcal·kg−1·day−1. Carbohydrates accounted for 54.3% ± 8.8% of the energy intake; 20.3% ± 6.5% from fats; 25.4% ± 5.7% from proteins. Conclusions Current data suggest that, although a cause-effect relationship between dietary intake and BC performance cannot be determined, elite athletes in these sports disciplines may experience beneficial outcomes despite having lower total energy, CHO, protein, and fat intakes than previously recommended in the literature.

Effect of educational intervention based on the theory of planned behavior (TPB) on amount of salt intake in pregnant women with PreHypertension

BackgroundPrehypertension is one of the common disorders during pregnancy. Reducing salt intake is among the best cost-effective interventions to reduce the risk of hypertension. The present study aimed to explore the effect of an educational intervention based on the Theory of Planned Behavior (TPB) on amount of salt consumed by prehypertensive pregnant women.MethodsThe present quasi-experimental study was conducted in 2022 on 61 prehypertensive pregnant women visiting the Comprehensive Health Services Centers in Birjand, Iran. Pregnant women were selected through a convenience sampling method and randomly assigned to intervention and control groups. A blood pressure test and a 24-hour urine test were taken in 3 stages (before, immediately after, and one month after the intervention). A reliable and valid questionnaire based on the TPB was used to measure the cognitive variables. The intervention program included three training sessions based on the TPB held on an online platform (WhatsApp social network). Data were analyzed using repeated measures ANOVA and longitudinal marginal model with the GEE approach in SPSS19. The significance level for all statistical tests was set at p < 0 0.05.ResultsAfter intervention, the mean score of perceived behavioral control (p = 0.02), intention (p = 0.004), and salt consumption behavior (p = 0.03) increased significantly in the intervention group, and the mean score of systolic blood pressure (p < 0.001) and diastolic blood pressure (P < 0.01) decreased significantly in this group. In the control group, a statistically significant difference was observed in the systolic and diastolic blood pressure of the subjects (p < 0.01). However, the score of attitude, subjective norms, perceived behavioral control, intention, salt consumption behavior and the daily salt intake did not show a statistically significant difference over time (P < 0.05).ConclusionThe present findings showed that the perceived behavioral control, intention, behavior, systolic and diastolic blood pressure can be modifiable variables to improve the amount of salt consumed by pre-hypertensive pregnant women. Therefore, we recommend that the present model be used to develop interventions to improve health indicators in pregnant women as a highly susceptible group in society.

Application and Enlightenment of High Frequency Pressure Monitoring in Fracturing of Fengxi Block

Abstract Volumetric fracturing of large-scale horizontal Wells is one of the important techniques for unconventional oil and gas production. However, there are no effective quantitative methods to describe key parameters such as fracture size and formation flow parameters. The high frequency pressure monitoring technology is to install a high frequency pressure gauge at the wellhead, and obtain the fracture initiation position and the sealing property of the bridge plug through monitoring and analysis of the water hammer wave during the period of pump shutdown. At the same time, the fracturing scale, permeability and the original formation pressure are obtained by combining the analysis of seepage pressure. On the basis of quantitative monitoring results, the relationship between fracture parameters and geological and engineering factors is deeply analyzed, and the following conclusions are obtained. (1) The number of fractures opened is mainly affected by the physical properties of the reservoir, which in turn affects the amount of liquid intake and sand of the single cluster opened, and finally affects the length and height of fractures in the core area. (2) The fracture morphology is affected by the construction scale and reservoir mechanical properties of a single cluster, while the SRV of the core area and the overall SRV are more affected by the overall construction scale.
