Reference ranges of uterine artery pulsatility index from first to third trimester based on serial Doppler measurements: longitudinal cohort study.

To provide gestational-age (GA)-specific reference ranges for mean uterine artery (UtA) pulsatility index (PI) based on longitudinal data assessment throughout pregnancy. This was a prospective longitudinal cohort study of singleton low-risk pregnancies with adequate health and nutritional status at the time of enrolment and without fetal anomaly, receiving prenatal care between January 2018 and July 2021 at the Maternal Fetal Medicine Unit of IRCCS San Raffaele Scientific Institute, Milan, Italy. Women were recruited at ≤ 12 + 6 weeks' gestation and underwent serial standardized ultrasound monitoring, including UtA-PI measurement, by experienced certified operators until delivery. Association of UtA-PI with GA was modeled with fractional polynomial regression. Equations for mean ± SD of the estimated curves were calculated, as well as GA-specific reference charts of centiles for UtA-PI from 10 + 0 to 39 + 0 gestational weeks. We included 476 healthy, low-risk pregnant women and a total of 2045 ultrasound scans (median, 4 (range, 3-9) per patient) were available for analysis. Mean UtA-PI was 1.84 ± 0.55, 1.07 ± 0.38 and 0.78 ± 0.23 in the first, second and third trimesters of pregnancy, respectively. Goodness-of-fit assessment revealed that second-degree smoothing was the most accurate fractional polynomial for describing the course of UtA-PI throughout gestation; therefore, it was modeled in a multilevel framework for the construction of UtA-PI curves. We observed a rapid and substantial decrease in mean UtA-PI before 16 weeks, with subsequent smoother decrement of the slope and more stable values from 20 until 39 weeks. The 3rd , 5th , 10th , 25th , 50th , 75th , 90th , 95th and 97th centiles according to GA for UtA-PI are provided, as well as equations to allow calculation of any value as a centile. UtA-PI shows a progressive non-linear decrease throughout pregnancy. The new reference ranges for GA-specific mean UtA-PI constructed using rigorous methodology may have a better performance compared with previous models for screening for placenta-associated diseases in the early stages of pregnancy and for evaluating the potential risk for pregnancy-induced hypertension and/or small-for-gestational age later in pregnancy. © 2022 The Authors.

Prevalence of Malnutrition in Hospitalized Patients in Lebanon Using Nutrition Risk Screening (NRS-2002) and Global Leadership Initiative on Malnutrition (GLIM) Criteria and Its Association with Length of Stay.

(1) Background: Prevalence studies on hospital malnutrition are still scarce in the Middle East region despite recent global recognition of clinical malnutrition as a healthcare priority. The aim of this study is to measure the prevalence of malnutrition in adult hospitalized patients in Lebanon using the newly developed Global Leadership Initiative on Malnutrition tool (GLIM), and explore the association between malnutrition and the length of hospital stay (LOS) as a clinical outcome. (2) Methods: A representative cross-sectional sample of hospitalized patients was selected from a random sample of hospitals in the five districts in Lebanon. Malnutrition was screened and assessed using the Nutrition Risk Screening tool (NRS-2002) and GLIM criteria. Mid-upper arm muscle circumference (MUAC) and handgrip strength were used to measure and assess muscle mass. Length of stay was recorded upon discharge. (3) Results: A total of 343 adult patients were enrolled in this study. The prevalence of malnutrition risk according to NRS-2002 was 31.2%, and the prevalence of malnutrition according to the GLIM criteria was 35.6%. The most frequent malnutrition-associated criteria were weight loss and low food intake. Malnourished patients had a significantly longer LOS compared to patients with adequate nutritional status (11 days versus 4 days). Handgrip strength and MUAC measurements were negatively correlated with the length of hospital stay. (4) Conclusion and recommendations: the study documented the valid and practical use of GLIM for assessing the prevalence and magnitude of malnutrition in hospitalized patients in Lebanon, and highlighted the need for evidence-based interventions to address the underlying causes of malnutrition in Lebanese hospitals.

Mobile health technology, exercise adherence and optimal nutrition post rehabilitation among people with Parkinson’s Disease (mHEXANUT) – a randomized controlled trial protocol

BackgroundAlthough it is well known that regular physical activity and exercise, as well as maintaining adequate nutritional status is important to delaying symptom development and maintaining physical capacity and function in people with Parkinson’s Disease (PD), many are unable to follow self-management recommendations. Active interventions have shown short-term effects, but there is a need for interventions that facilitate self-management over the course of the disease. Until now, no studies have combined exercise and nutritional interventions with an individual self-management approach in PD. Thus, we aim to examine the effect of a six-month mobile health technology(m-health)-based follow-up programme, focusing on self-management in exercise and nutrition, after an in-service interdisciplinary rehabilitation programme.MethodsA single-blinded, two-group randomised controlled trial. Participants are Adults aged 40 or older, with idiopathic PD, Hoehn and Yahr 1–3, living at home. The intervention group receives a monthly, individualized, digital conversation with a PT, combined with use of an activity tracker. People at nutritional risk get additional digital-follow-up from a nutritional specialist. The control group receives usual care. The primary outcome is physical capacity, measured by 6-min walk test (6MWT). Secondary outcomes are nutritional status, Health related quality of life (HRQOL), physical function and exercise adherence. All measurements are performed at baseline, after 3 months and after 6 months. Sample size, based on primary outcome, is set at 100 participants randomized into the two arms, including an estimated 20% drop out.DiscussionThe increasing prevalence of PD globally makes it even more important to develop evidence-based interventions that can increase motivation to stay active, promote adequate nutritional status and improve self-management in people with PD. The individually tailored digital follow-up programme, based on evidence-based practice, has the potential to promote evidence-based decision-making and to empower people with PD to implement exercise and optimal nutrition in their daily lives and, hopefully, increase adherence to exercise and nutritional recommendations.Trial registrationClinicalTrials.gov (NCT04945876).

Iodine status in pregnant women in northern Spain. Effect of iodised salt and iodine supplements on thyroid function

IntroductionIodine deficiency is linked to thyroid dysfunction, particularly in pregnant women. The objective of this study was to ascertain the iodine levels of women in the second trimester of pregnancy, analysing the influence of iodine ingestion on urinary iodine concentration (UIC) and maternal thyroid function. MethodsA prospective observational study of pregnant women from Health Area IV of Asturias (northern Spain) recruited before 13 weeks of gestation between May and June 2017. A questionnaire on iodine intake was completed at the first visit, and urine and serum samples were collected at baseline and again during the second trimester. UIC, thyroid stimulating hormone (TSH) and free thyroxine (FT4) obtained in the second trimester of gestation were analysed and related to iodine intake. Thyroid autoimmunity was also analysed in half of the pregnant women at baseline. ResultsA total of 241 pregnant women were studied. Of these, 56.7% used iodised salt, 46.7% consumed ≥2 servings of dairy products daily and 88.1% took iodine supplements. Median UIC was 191μg/l (135.3–294μg/l), with 68.1% of the women having UIC ≥150μg/l. Only iodised salt consumption provided protection against iodine deficiency (odds ratio 0.35 [0.20–0.63], p=0.001). In women with no autoimmune thyroid disease (n=88), mean levels of TSH were lower in those that consumed iodised salt than in those that did not (respectively, 2.08±0.89mIU/l vs. 2.56±1.02mIU/l, p=0.025). In women with autoimmune thyroid disease (n=30), mean levels of TSH were higher in those that took iodine supplements than in those that did not (respectively, 2.97±1.25mIU/l vs. 1.16±0.41mIU/l, p=0.002). ConclusionsThe pregnant women studied from Health Area IV in Asturias maintain adequate nutritional iodine status in the second trimester of gestation. In our sample, only the consumption of iodised salt was associated with adequate iodine nutrition, without affecting maternal thyroid function. Most of the women used iodine supplements, which was linked to higher levels of TSH in pregnant women with autoimmune thyroid disease.

Body Composition and Nutritional Status of the Spanish National Breaking Team Aspiring to the Paris 2024 Olympic Games

Breaking is a sports dance modality that will debut for the first time at the Paris 2024 Olympic Games. This dance form combines street dance steps with acrobatics and athletic elements. It complies with gender equality, maintains aesthetic appeal, and is practised indoors. The objective of this study is to assess the characteristics of body composition and nutritional status of the athletes that make up the Breaking national team. This national team was recruited, and they underwent an analysis of body composition using bioimpedance measurement and a nutritional interview status with the completion of a survey on the frequency of the consumption of sports supplements and ergogenic aids. In addition, they completed a consumption questionnaire for a series of food groups with specified protein, lipid, and carbohydrate content. After that, parameters were analyzed in relation to their nutritional status during a complete medical examination at the Endocrinology and Nutrition Service of the Sports Medicine Center of CSD. A descriptive analysis of the results obtained was carried out to find the mean values of the variables analyzed. The analytical parameters described an adequate nutritional status, except for the mean capillary determination of 25-OH-vitamin D3, which was 24.2 ng/dL (SD: 10.3). Bone mineral density values were higher than those of the general population. This is the first time that a study of these characteristics has been carried out on Breakers, so it is highly relevant to increase knowledge in this area in order to conduct nutritional interventions aimed at improving the sports performance of these athletes.

Dietary practices and nutritional status of children served in a social program for surrogate mothers in Colombia

BackgroundDietary practices are acquired in the family context and in turn can affect the health of family members, especially the nutritional status of children. The objective of this study was to determine the relationship between nutritional status and feeding practices in children from foster families served by the SOS Children's Villages program in Cartagena, Colombia.MethodsThe study had a cross-sectional design. Through a non-probabilistic purposive sampling, 139 children from 0 to 5 years of age from the SOS Children's Villages Cartagena program were involved. The sociodemographic background of the participants was recorded and the nutritional status of the children was evaluated through anthropometric and biochemical measurements. Dietary practices were measured by means of a standardized questionnaire. Analyses were performed with Poisson regression models with robust variance. These regression models provided prevalence ratios (PR) with their respective 95% confidence intervals (95%CI).ResultsAmong dietary practices, it was observed that most families eat together at home (63.3%), watch television when they eat (55.4%), and have dietary norms (80.6%). Consumption of plant foods was predominantly high, especially vegetables (86.3%), fruits (92.1%), cereals (84.9%), root vegetables, and bananas (93.5%). Consumption < 4 times/week of soft drinks and industrialized juices increases 14.3 times the probability of low weight-for-height in the study population compared to the group that does not consume them. On the other hand, watching television while eating (PR: 2.82, 95%CI 1.32—4.69) and consumption of sweet snacks (PR: 2.24, 95%CI 1.03—4.87) increased the probability of low height-for-age; while having eaten norms at home decreased the probability of low height-for-age in the study population by 50%.ConclusionIt is necessary to develop and implement interventions such as preventive measures and early diagnosis of inappropriate feeding behaviors to ensure adequate nutritional status among children under 5 years of age.

Impact of malnutrition on postoperative outcomes of patients undergoing gastrectomy for gastric cancer: A nationwide analysis between 2012 and 2017.

315 Background: Gastrectomy offers a curative treatment option for non-metastatic gastric cancers (GC). Unfortunately, cancer associated malnutrition is a common and potentially actionable problem in GC patients. In this nationwide study, we analyzed the impact of malnutrition on outcomes of patients undergoing gastrectomy for GC. Methods: The Nationwide inpatient Sample database (NIS) was used to identify patients who underwent gastrectomy for gastric cancer from 2012-2017 using ICD 9 and ICD 10 codes. The population was then divided into patients with or without PEM (Protein energy malnutrition) to compare their outcomes. Univariate and Multivariable logistic and linear regression models were used to analyze mortality and healthcare resource utilization. Results: Of the 6,620 patients identified, 4,607 (69.6%) patients were ≥ 60 years old and 3,972 (60%) were males. Majority were White (49.1%) followed by Asians (20.3%). 2,052 (31%) patients were malnourished. Patients with PEM had higher rates of sepsis [adjusted Odds ratio (aOR) 3.6(2.4-5.4), p =0.000], shock [aOR 2.9(1.9-4.5), p =0.000], acute kidney injury [aOR 2.1(1.5-2.9), P&lt;0.001], ICU admissions [ aOR 1.9(1.3-2.9), p =0.001], and higher post operative mortality [aOR 2.5 (1.5-4.3), p =0.001]. Mean Length of stay was longer in PEM patients as compared to non-PEM patients (16.2 vs 9.4 days). On survival analysis, overall survival (OS) was significantly worse for patients with PEM undergoing gastrectomy [HR adj: 1.14 (p=0.04)]. A comparison of these outcomes has been detailed in the table. Conclusions: In this analysis, we highlight the importance of nutrition for gastric cancer patients undergoing gastrectomy. Ensuring adequate nutritional status prior to surgery can improve patient outcomes and decrease health care costs.[Table: see text]

Association of pre-pregnancy maternal overweight/obesity and dietary intake during pregnancy with the concentrations of persistent organic pollutants in the human milk of women from Rio de Janeiro, Brazil.

Persistent organic pollutants (POPs) are toxic chemical compounds that can bioaccumulate, adhere to lipid matrices, and affect human health. This study aimed to investigate the association between maternal pre-pregnancy overweight/obesity and dietary intake during pregnancy and POP concentrations in the human milk of women from Rio de Janeiro, Brazil. One hundred and forty-seven women were followed from the third trimester of pregnancy until 119days postpartum, and 77 human milk samples were analyzed between 2 and 119days postpartum. POP concentrations were analyzed using gas chromatography-triple quadrupole mass spectrometry. Pregnancy dietary intake was estimated using a semi-quantitative food frequency questionnaire, and pre-pregnancy body mass index at baseline was classified as normal or overweight/obesity. Multiple logistic and linear regression models were performed to investigate the association between pre-pregnancy overweight/obesity, dietary intake during pregnancy, and POP concentrations in human milk. The models were adjusted for maternal age, maternal schooling, total cholesterol serum concentrations, and time postpartum. The analyses were corrected for multiple comparisons using the Benjamini-Hochberg test. Significant associations were observed between pre-pregnancy overweight/obesity and dichlorodiphenyldichloroethane (ppDDE), polychlorinated biphenyl (PCB)74, PCB138, PCB153, PCB170, PCB180, total PCBs, total 4PCBs, total 2 organochlorine pesticides (OCPs), and total POP concentrations. Higher daily lipid intake during pregnancy increased human milk hexachlorobenzene (HCB). This study showed that pre-pregnancy overweight/obesity and total lipid intake during pregnancy were associated with POP concentrations in the milk of women from Rio de Janeiro, Brazil. To promote adequate nutritional status since preconception and surveillance and control of POP in the environment could be essential to ensure binomial mother-infant health and biomonitoring studies and programs for these POPs should be stimulated.

ALAD and APOE polymorphisms are associated with lead and mercury levels in Italian pregnant women and their newborns with adequate nutritional status of zinc and selenium

The impacts of single-nucleotide polymorphisms (SNPs) in ALAD and VDR genes on Pb health effects and/or kinetics are inconclusive at low exposure levels, while studies including APOE SNPs are rare. In this study, we examined the associations of ALAD, VDR and APOE SNPs with exposure biomarkers of Pb and other trace elements (TEs) in Italian pregnant women (N = 873, aged 18–44 years) and their newborns (N = 619) with low-level mixed-element exposure through diet, the environment or endogenously. DNA from maternal peripheral venous blood (mB), sampled during the second and third trimesters, was genotyped for ALAD (rs1800435, rs1805313, rs1139488, rs818708), VDR (rs2228570, rs1544410, rs7975232, rs731236) and APOE (rs429358, rs7421) using TaqMan SNP assays. Personal and lifestyle data and TE levels (mB, maternal plasma, hair and mixed umbilical cord blood [CB]) from the PHIME project were used. Multiple linear regression models, controlling for confounding variables, were performed to test the associations between SNPs and TEs. The geometric means of mB-Pb, mB-Hg, mB-As and mB-Cd (11.0 ng/g, 2.16 ng/g, 1.38 ng/g and 0.31 ng/g, respectively) indicated low exposure levels, whereas maternal plasma Zn and Se (0.72 μg/mL and 78.6 ng/g, respectively) indicated adequate micronutritional status. Variant alleles of ALAD rs1800435 and rs1805313 were negatively associated with mB-Pb levels, whereas a positive association was observed for rs1139488. None of the VDR SNPs or their haplotypes had any association with Pb levels. Regarding APOE, the ϵ4 allele was associated with lower mB-Hg and CB-Hg, while a positive association was found with the ϵ2 allele and CB-Pb when the model included only newborn girls. The observed associations indicate possible modification effects of ALAD and APOE SNPs on Pb or Hg kinetics in women and their newborns with low exposure to non-essential TEs, as well as an adequate nutritional status of Zn and Se.

Effects of Chromium, Inositol and Resistant Starch Supplementation In Pcos

Polycystic ovary syndrome (PCOS) is a diverse condition that has distinct signs and symptoms such as hyperandrogenism and chronic anovulation. It is a major hormonal disorder that affects the health-related quality of life and mental health of young women. The etiology of PCOS still remains uncertain but insulin resistance is one of the major factors seen in PCOS individuals which are characterized by the presence of acanthosis nigricans. Dietary interventions and lifestyle modification are being considered to be a first-line treatment for women with PCOS. Proper diet, adequate nutritional status, and following a physical activity routine help in alleviating the symptoms of PCOS. Dietary interventions should focus on weight management and insulin regulation. An abnormal gut microbiome function results in ovarian dysfunction, immune changes, insulin resistance, and disruption in bile synthesis. Therefore, gut health of women suffering from PCOS should be prioritized and interventions that improve the gut health should be followed. This systematic review is performed to investigate the association between micronutrient supplementation and PCOS. The related articles were searched using the databases PubMed, Science Direct, and Google Scholar. All the studies involving micronutrient supplementation and PCOS were included in this systematic review. Micronutrient supplementation was significantly inversely associated with improving PCOS prognosis. The main finding of the systematic review is that it concludes there is a direct association between micronutrient supplementation as it helps in alleviating the symptoms and maintaining a proper lifestyle in women with PCOS.

SADI-S with Extended Duodeno-Bulb Preservation: Case Report

Obesity has been growing in Brazil and in the world. It is reaching epidemic proportions, and bariatric surgery is the most effective treatment for patients with this disease. Among the procedures described in the literature, ileal surgeries such as biliopancreatic diversion with duodenal switch (BPD-DS) and single-anastomosis duodeno-ileal bypass with sleeve gastrectomy (SADI-S) present better long-term results in terms of weight loss and comorbidities control. However, there are concerns regarding long term nutritional problems with these procedures. In this case report the aim is to demonstrate the technical feasibility of preserving an extended duodenal bulb segment, in the SADIS-S procedure, when there are difficulties in dissecting the retrobulbar region, as occurred here, due to fibrosis in this area. This assures the maintenance of the proposed surgical technique, in such a situation. The dissection and transection of the duodenum was done 7 cm distally to the pylorus, under endoscopic view, proximally to the papillae, where the tissue was normal. Additionally, due the importance of the duodenal mucosa on minerals and trace elements absorption and the release of important hormones in this region, this case report elicits the evaluation of the impact of this technical modification, which occurred casually, in the nutritional, hormonal and metabolic results, long term. In this case report, the extended duodenal length has demonstrated reasonable weight loss, adequate comorbidities control and good nutritional status, so far. These aspects must be evaluated in the long term, by clinical trials.

Association of anemia with BMI in paramedical students of the remote and rural high land of Mid-Western Nepal

Background and Objectives: Anemia is a widespread public health issue. It impairs immune systems and is linked to an increase in morbidity. Additional factors linked to lower hemoglobin (Hb) levels in adolescents include lack of awareness, low educational status, poor dietary practices, and unhealthy eating habits, low iron bioavailability of the diet, decreased physical activity, malaria, and parasite infestations. Studies on the incidence and severity of anemia among Nepali college students are extremely rare. The significance of research on the prevalence of anemia among college students cannot be underestimated. The study's objective was to evaluate the relationship between anemia and BMI in paramedical students from the isolated, rural highlands of Midwestern Nepal. Materials and Methods: A quantitative cross-sectional study was conducted among the paramedical students of KAHS. A total of 96 students from paramedical students were participated in this study. Before collecting the data, the consent was taken from students. Data were collected from a semi-structured questionnaire and analyze by using SPSS software (20.0 Version). A chi square test was used to show the relationship between demographic variables and anemia. Results: The prevalence of anemia was 20.8% (male=6.1% and female=53.3%) among the 96 students. There was no significant association between anemia and BMI (P&gt;0.05). Conclusion: The anemic status of students was significantly associated with gender but BMI and age where not the factors of anemic status in this Therefore, there should be adequate diet and nutritional status needs to be emphasized for paramedical students who are well educated and well oriented about nutrition and its ill effect on health.

Immunonutrition Associated with the Protein Module in the Nutritional Evolution of Lung Cancer Patients Undergoing Systemic Treatment: Case Report

Background: Lung cancer patients are at high risk of malnutrition. Methods: Case report of two elderly patients diagnosed with lung cancer were followed up during chemotherapy and/or immunotherapy. Patients used nutritional supplementation combined with immunonutrition and Whey Protein module alone during 4 treatment cycles. For nutritional and functional assessment, the following were used: Body Mass Index, percentage of weight loss, calf circumference, Patient Generated Subjective Global Assessment, muscle strength by dynamometer, SARC-F, Barthel Index, biochemical tests and food recall of 24 hours. Results: During follow-up, patients were able to maintain adequate nutritional status, as well as functionality, and were not at risk for sarcopenia. Muscle strength varied, but not significantly. Conclusion: Immunonutrition associated with the protein module appears to be beneficial in cancer patients during systemic treatment.

Assessment of Eating Habits and Preconception and Gestational Nutritional Status of Women Who Attended the Prenatal Service of a Brazilian University Hospital

Introduction Adequate nutritional status should be seen as a fundamental point of prenatal care to avoid obstetric complications and promote the baby’s health. This study aimed to compare prenatal body mass index (BMI) and BMI for gestational age (GA) and lifestyle habits of high-risk and low-risk pregnant women at a Brazilian University Hospital. Methodology This is a descriptive cross-sectional study with a quantitative approach using a questionnaire. Statistical analyzes were performed using Statistical Package for Social Sciences (SPSS) version 26.0. The significance level adopted was 5% (p&lt;0.05). Results The present research involved 78 pregnant women, 51.3% of whom were low-risk. Most pregnant women (73.1%) did not practice physical activity and, among those who did, most reported practicing between 2 and 3-hours per week of light activity. In addition, most (57.7%) interviewees reported sleeping more than 7-hours a night. The pre-pregnancy BMI was adequate in only 34.6% of the patients, while 59% were overweight (overweight or obese); at the time of the interview, BMI for gestational age was normal in only 28.2%, and 66.7% had a BMI reflecting overweight. Consumption of sweets during the week showed significant variation: the high-risk group had a higher percentage of patients who did not consume sweets during the week (44.7%) compared to the low-risk group (20%). Furthermore, while in the high-risk group, only 7.9% consumed sweets 5 to 7 times a week, 30% of the low-risk group consumed sweets 5 to 7 times a week. Conclusion The evaluated pregnant women have a prevalence of excess weight of 66.6%, higher than that of Brazilian women (53.9%). Comparison between preconception BMI and BMI for GA showed a tendency to persist in the pre-pregnancy classification; when there was a change in the distribution of the BMI classification, this occurred with a reduction in the number of underweight, eutrophic, and overweight women and an increase in the percentage of pregnant women with obesity. The diet, in general, was sufficient in terms of micronutrients and fiber, but with high consumption of sweets by low-risk pregnant women. In addition, the proportion of sedentary pregnant women is extremely high. Our study shows the importance of promoting healthy habits during prenatal care to improve pregnant women’s nutritional diagnosis

Iodine status in pregnant women in northern Spain. Effect of iodised salt and iodine supplements on thyroid function

IntroductionIodine deficiency is linked to thyroid dysfunction, particularly in pregnant women. The objective of this study was to ascertain the iodine levels of women in the second trimester of pregnancy, analysing the influence of iodine ingestion on urinary iodine concentration (UIC) and maternal thyroid function. MethodsA prospective observational study of pregnant women from Health Area IV of Asturias (northern Spain) recruited before 13 weeks of gestation between May and June 2017. A questionnaire on iodine intake was completed at the first visit, and urine and serum samples were collected at baseline and again during the second trimester. UIC, thyroid stimulating hormone (TSH) and free thyroxine (FT4) obtained in the second trimester of gestation were analysed and related to iodine intake. Thyroid autoimmunity was also analysed in half of the pregnant women at baseline. ResultsA total of 241 pregnant women were studied. Of these, 56.7% used iodised salt, 46.7% consumed ≥2 servings of dairy products daily and 88.1% took iodine supplements. Median UIC was 191μg/l (135.3–294μg/l), with 68.1% of the women having UIC ≥150μg/l. Only iodised salt consumption provided protection against iodine deficiency (odds ratio 0.35 [0.20–0.63], p=0.001). In women with no autoimmune thyroid disease (n=88), mean levels of TSH were lower in those that consumed iodised salt than in those that did not (respectively, 2.08±0.89mIU/l vs. 2.56±1.02mIU/l, p=0.025). In women with autoimmune thyroid disease (n=30), mean levels of TSH were higher in those that took iodine supplements than in those that did not (respectively, 2.97±1.25mIU/l vs. 1.16±0.41mIU/l, p=0.002). ConclusionsThe pregnant women studied from Health Area IV in Asturias maintain adequate nutritional iodine status in the second trimester of gestation. In our sample, only the consumption of iodised salt was associated with adequate iodine nutrition, without affecting maternal thyroid function. Most of the women used iodine supplements, which was linked to higher levels of TSH in pregnant women with autoimmune thyroid disease.

Evaluation of a Dietary Supplementation Combining Protein and a Pomegranate Extract in Older People: A Safety Study

Malnutrition is a highly prevalent condition in older adults. It is associated with low muscle mass and function and increased occurrence of health problems. Maintaining an adequate nutritional status as well as a sufficient nutrient intake in older people is therefore essential to address this public health problem. For this purpose, protein supplementation is known to prevent the loss of muscle mass during aging, and the consumption of various pomegranate extracts induces numerous health benefits, mainly through their antioxidant properties. However, to our knowledge, no study has to date investigated the impact of their combination on the level of malnutrition in older people. The objective of this preliminary study was thus to evaluate the safety of a combination of protein and a pomegranate extract in healthy subjects aged 65 years or more during a 21-day supplementation period. Thirty older participants were randomly assigned to receive protein and a pomegranate extract (Test group) or protein and maltodextrin (Control group) during a 21-day intervention period. The primary outcomes were the safety and tolerability of the supplementation defined as the occurrence of adverse events, and additional secondary outcomes included physical examination and hematological and biochemical parameters. No serious adverse events were reported in any group. Changes in physical, hematological, and biochemical parameters between the initial screening and the end of the study were equivalent in both groups, except for glutamate-pyruvate transaminase (GPT) and prealbumin, for which a decrease was observed only in the Test group. Our initial findings support the safety of the combination of protein and a pomegranate extract in healthy elderly people. Future clinical trials on a larger sample and a longer period are needed to determine the efficacy of this combination.

Percutaneous trans-stomal jejunostomy: a new technique.

We propose a new technique for feeding a malnourished patient with a "high" double-barrel jejunostomy (at about 60cm from the Treitz Ligament). The procedure aims to restore an adequate nutritional state maintaining a correct diet for 24h a day, without complications and without interfering with the normal activity of the nurses caring for the stoma. Using local anesthesia, we introduced a Reverdin needle through the efferent loop of jejunostomy and externalized it through the skin, medially from jejunostomy of about 10cm. Using this guide, we inserted an enteral feeding tube with a blunt tip and then introduced it through the efferent loop to reach about 40cm distantly into the bowel. The stoma output decreased from 3 to 1.5L/day; kidney status was restored to normal function. The main advantages are the minimal invasiveness of the implantation procedure, the possibility of nutrition during all 24h, and the easy management by nurses.

Variability and Seasonal Change of Urinary Selenium, Molybdenum, and Iodine Excretion in Healthy Young Japanese Adults.

Selenium (Se), molybdenum (Mo), and iodine (I) are essential trace elements or nutrients and their adequate intake is essential for human health. These elements in foods are easily absorbed from the digestive tract and excreted predominantly into the urine, and their nutritional status is reflected in urinary excretion; however, information on the variability of urinary excretion is limited. To characterize the urinary Se, Mo, and I concentrations and their intra- and inter-individual coefficients of variation (CV), correlation, and seasonal change, spot urine samples were collected from 24 healthy university students, 10 males and 14 females, with the mean age of 20.6years, for 10 consecutive days in each of the four seasons according to a defined schedule of an interval of 3months throughout 1year. The median Se, Mo, and I concentrations for all urine samples (n = 947) were 52.8, 127.0, and 223μg/L, respectively. The Se and Mo intakes were highest in summer and lowest in spring, while the I intake was highest in autumn and lowest in summer. In all three elements, the intra-individual CVs were smaller than their inter-individual CVs. The log-transformed intra- and inter-individual CVs were 10.5 and 14.7% for Se, 12.3 and 15.1% for Mo, and 15.5 and 18.1% for I. There was no gender difference in Se and I concentrations, while Mo and Mo/Cr values in males were higher than those in females. Our results suggest adequate nutritional status of Se, Mo, and I with a relatively smaller variability of dietary intake except for I in this population.

Nutritional Support in Pancreatic Diseases.

This review summarizes the main pancreatic diseases from a nutritional approach. Nutrition is a cornerstone of pancreatic disease and is sometimes undervalued. An early identification of malnutrition is the first step in maintaining an adequate nutritional status in acute pancreatitis, chronic pancreatitis and pancreatic cancer. Following a proper diet is a pillar in the treatment of pancreatic diseases and, often, nutritional counseling becomes essential. In addition, some patients will require oral nutritional supplements and fat-soluble vitamins to combat certain deficiencies. Other patients will require enteral nutrition by nasoenteric tube or total parenteral nutrition in order to maintain the requirements, depending on the pathology and its consequences. Pancreatic exocrine insufficiency, defined as a significant decrease in pancreatic enzymes or bicarbonate until the digestive function is impaired, is common in pancreatic diseases and is the main cause of malnutrition. Pancreatic enzymes therapy allows for the management of these patients. Nutrition can improve the nutritional status and quality of life of these patients and may even improve life expectancy in patients with pancreatic cancer. For this reason, nutrition must maintain the importance it deserves.
