The aim of this study was to determine the concentrations of alpha- and gamma-tocopherols in human breast milk samples from different periods of lactation and to compare them with tocopherol content in commercially available formulas for infants at corresponding ages. The study included 93 breast milk samples obtained on the 2nd (colostrum, n = 17), 14th (n = 30), 30th (n = 27) and 90th day of lactation (n = 19), along with 90 samples of commercially available initial and follow-on infant formulas. Concentrations of tocopherols were determined using normal-phase high-performance liquid chromatography. Depending on the stage of lactation, human breast milk contained 2.07-9.99 mg L⁻¹ of alpha-tocopherol and 0.22-0.60 mg L⁻¹ of gamma-tocopherol. Breast milk concentrations of alpha-tocopherol decreased with the time of lactation, while significant differences in gamma-tocopherol concentration were observed only between the 14th and 30th day of lactation. There was no significant correlation between the dietary intake of vitamin E and its estimated breast milk concentration, also in women who declared vitamin supplementation. Compared with colostrum, infant formulas were characterised by significantly lower concentrations of alpha-tocopherol and vitamin E. This finding indicates the need of additional vitamin E supplementation of bottle-fed infants during the initial 2-3 days of life.
Introduction?We present the experiences from two European centers performing the Foker technique (FT) of esophageal lengthening by axial traction and the Kimura advancement (KA) method of lengthening the upper pouch by extrathoracic resiting a spit fistula (SF) in children with long-gap esophageal atresia (LGEA, gap length?>?5 cm). Materials and Methods?A total of 15 children were treated (8 pure EA, 6 lower tracheoesophageal fistula [TEF], and 1 upper TEF). Gaps ranged from 5 to 14 cm. Nine children already had a SF. Patients were grouped according to the presence of a SF and the subsequent surgical strategy: Group A (no SF, n?=?6) received FT on both pouches. Group B (with SF, n?=?6) received KA of SF and FT of the lower pouch. Group C (with SF, n?=?3) received closure of the SF and subsequent Foker traction (CSFT) on both pouches. Results?Group A: Primary repairs for all six children (mean age 3 months, gap length 6.5 cm) after a mean traction time of 3 weeks and a mean of 2.1 thoracotomies (range 2 to 3). Dilations were required in three out of six for anastomotic strictures with one perforation during the second dilation. Group B: All six children (mean age 16.4 months, gap length 9.5 cm) had a primary anastomosis, although for two it was significantly delayed (48 and 143 weeks traction time) because of infections. The number of thoracotomies ranged from 2 to 8 (mean 3.6). Leaks occurred in five out of six anastomoses (responsive to conservative management). Two children developed severe strictures, which required the anastomosis to be redone. In group C (mean age 10.6 months, gap length 6.5 cm), several major complications occurred. The three SF closures leaked (one iatrogenic) causing severe mediastinitis. CSFT was successful in only one case and the other two children had an esophageal replacement (stomach, jejunum). No deaths occurred in the series. Conclusion?FT of both pouches (group A) resulted in primary repairs of all six LGEA patients. The combination of KA and FT (group B) resulted in an equivalent rate of primary repairs, but with an increased number of thoracotomies and rate of complications compared with group A. CSFT (group C) resulted in a high failure rate. More data are needed (we propose a multicenter registry) to elucidate the safety and efficacy of each elongation technique and to establish an algorithm with clearer inclusion and exclusion criteria.
Published epidemiologic data on the administration rates of enteral/parenteral home nutrition is very limited. The aim of this first nationwide study was to assess the availability of pediatric home enteral nutrition (HEN) services in Poland. The questionnaire was sent to all regional centers providing pediatric HEN services in Poland (n = 14). The analysis included the number of pediatric patients who received HEN in 2010, their demographic characteristics and geographical distribution. Furthermore, the distributions of indications and methods of enteral nutrition administration were analyzed, along with the reasons of withdrawal from the HEN program. The number and fraction of children receiving HEN increased in 2010, from 433 (11.34 per 1 million inhabitants) on January 1st to 525 (13.75) on December 31st. Marked differences were observed in geographical distribution of this parameter, from zero to up to 30 pediatric patients per 1 million inhabitants. Median age of patients was 6 years (range: 9 months–18 years). In most cases, HEN was prescribed due to neurological disorders (n = 337, 64.2%), and administered by means of gastrostomy (n = 450, 85.71%). This study revealed the dynamic development of pediatric HEN services in Poland but also documented their potential regional shortages.
BackgroundObesity is associated not only with an array of metabolic disorders (e.g. insulin resistance, hiperinsulinemia, impaired tolerance of glucose, lipid disorders) but also skeletal and joint abnormalities. Recently, a pleiotropic role of vitamin D has been emphasized. Obese children frequently present with vitamin D deficiency, and greater fat mass is associated with lower serum concentration of this vitamin. Although some evidence suggests that weight loss may affect vitamin D status, this issue has not been studied extensively thus far. The aim of a double-blind placebo-controlled study is to assess long-term health effects of vitamin D supplementation in vitamin D deficient obese children participating in an integrated weight-loss programme.MethodsA randomized double-blind, placebo-controlled trial analysing the effects of vitamin D3 supplementation in overweight or obese vitamin D deficient (<30 ng/ml) children participating in an integrated weight-loss programme. Children are randomized to receive either vitamin D (1200 IU) or placebo for 26 weeks. Primary endpoints include changes in BMI (body mass index), body composition and bone mineral density at the end of the study period, and secondary endpoints – the changes in laboratory parameter reflecting liver and kidney function (transaminases, creatinine) and glucose homeostasis (glucose and insulin levels during oral glucose tolerance test).DiscussionThe effects of vitamin D supplementation in obese individuals, especially children, subjected to a weight-loss program are still poorly understood. Considering physiological processes associated with puberty and adolescent growth, we speculate that supplementation may enhance weight reduction and prevent bone loss in obese children deficient in this vitamin.Trial registration NCT 02828228; Trial registration date: 8 Jun 2016; Registered in: ClinicalTrials.gov. The trial was registered retrospectively.
Background: The population of patients on home parenteral nutrition (HPN) worldwide is growing. Since only a few counties provide data from national registries long-term observations are valuable to address this specific area of nutrition support. This study is a nationwide analysis determining the trends in the epidemiology of HPN (prevalence, age distribution, death rates), indications for HPN, causes for hospitalizations, and cost analysis of HPN reimbursement in Poland between 2010–2020. Methods: A retrospective analysis of data obtained from the national health fund (NHF) of Poland on adult patients on HPN. Results: The prevalence of adult patients on HPN in Poland in 2020 was 53.26 per million citizens with a 2.99-fold increase and a growing trend observed from 2010. Significant decrease in the percentage of patients between 18–34, 45–54 and an increase in patients between 65–74 and patients over 75 years old was observed. Trend analysis showed an increase in new patients between 65–74 and a decrease between 35–54. Malnutrition (34.28%), postprocedural disorders of the GI tract (19.61%), intestinal malabsorption/other intestinal diseases (20.41%) and GI obstruction due to cancer (17.36% as primary and 23.16% as secondary diagnosis) were mostly reported as the primary indications for HPN. Cancer patients were mostly gastric, ovarian and colon cancer (34.74%, 17.83% and 12.3%). HPN and total health cost reimbursement increase was 2.6 and 2.57—fold respectively. Costs of HPN and total health care costs in 2020 per patient were € 10,015 and € 16,038, respectively. Overall death risk rate during the first year of nutrition was 0.59 with a significant increase in the observation period p-trend < 0.004. A significant increase in the death rate was observed in patients above 75 years old (estimate 1.629, p-trend < 0.030). Cancer, infection, malnutrition and GI symptoms were the most common indications for hospitalizations of HPN patients. The rate of patients with a maximal length of HPN of 5 months in 2010 was 54.9% and was growing up to 78.1% in 2020. Conclusions: The prevalence of HPN in Poland is growing. Trends of age distribution show increasing numbers of patients with more advanced age and shorter survival. Costs of HPN are comparable with other European data.
Background: While in the general paediatric population the presence of abnormal lipid values is estimated at 8-20%, depending on the population, accepted norms and age, it was shown that in the population of lean children the prevalence of dyslipidemia is lower than in obese children, in whom it ranges from 20 to over 40%. Until now, however, no results of similar studies on a large sample of children form a Central or Eastern European country have been published. The aim of this study was to evaluate the prevalence of lipid disorders in overweight and obese children and adolescents participating in an integrated weight reduction programme. Methods: According to the "6-10-14 for Health" programme implementation schedule, the programme accepted patients living in Gdańsk, aged 6, 9-11 and 14 years old, with BMI above the 85th percentile for age and sex, according to the Polish percentile charts. During the first visit, each of the participants underwent basic anthropometric examinations-body weight, body height, waist and hip circumference, blood pressure and body composition by bioelectrical impedance were measured. Blood samples were taken to assess lipid, glucose and insulin levels as well as alanine transaminase (ALT) and thyroid stimulating hormone (TSH) activity. Results: 1948 patients underwent full anthropomethric and blood work measurements. At least one of the lipid disorders occurred in 38.23% of girls and 40.51% of boys with overweight and obesity. The most common lipid disorderswere decreased high-density lipoprotein cholesterol (HDL-C) levels (present in 20.55% of the girls and 23.79% of the boys) and elevated low-density lipoprotein cholesterol (LDL-C) (present in 15.31% of the girls and 14.25% of the boys). There was no strong association between lipid disorders and age, sex, birth weight, gestational age at birth or body composition. Conclusions: Such a frequent occurrence of lipid disorders in the population of children and adolescents should be an important warning signal both at the individual and population level. Not only effective screening methods for overweight and obese children should be implemented from an early age but also therapeutic measures are required.
To determine transforming growth factor (TGF) beta(1), interleukin (IL) 4, and IL-10 concentrations in human milk and to assess the relationship between allergic disorders in mothers and the content of the interleukins in their milk. Thirty allergic and 46 healthy mothers were included in the study. Colostrum was collected 2-3 days after delivery. Cytokine concentrations were determined with commercial enzyme-linked immunosorbent systems. TGF-beta(1)was found in milk from 23 women in the control group (53.49%) and 11 in the allergy group (37.93%). When TGF-beta(1) was present, the median concentration was higher in the allergy group than in the control (61.5 and 30.4 pg/mL, respectively; P < 0.004). IL-10 was present in the colostrum of all the women and the median IL-10 concentration did not differ between the allergy (50.5 pg/mL) and control (51.5 pg/mL) groups. The probability of occurrence of a positive IL-4 value in the allergy group was greater than in the control group (chi-squared [df=1] = 2.60, P < 0.053). Median IL-4 level did not differ significantly between the two groups (0.5 and 0.5 pg/mL respectively). TGF-beta(1) was detected less often in the colostrum of allergic mothers than in that of mothers without allergy (but the difference was not statistically significant). IL-4 was found more often in the colostrum of allergic mothers than nonallergic ones. The allergy status did not correlate with IL-10 concentration.
