RESUMEN
PURPOSE: Vitamin D deficiency is related to metabolic disturbances. Indeed, a poor vitamin D status has been usually detected in patients with cardiovascular disease (CVD). However, the relationship between vitamin D and CVD risk factors in young adults remains controversial at present. This study aimed to examine the association between circulating 25-hydroxivitamin D (25(OH)D) and CVD risk factors in young adults. METHODS: The present cross-sectional study included a cohort of 177 young adults aged 18-25 years old (65% women). 25(OH)D serum concentrations were assessed using a competitive chemiluminescence immunoassay. Fasting CVD risk factors (i.e., body composition, blood pressure, glucose metabolism, lipid profile, liver, and inflammatory markers) were determined by routine methods. A panel of 63 oxylipins and endocannabinoids (eCBs) was also analyzed by targeted metabolomics. RESULTS: Circulating 25(OH)D concentrations were inversely associated with a wide range of CVD risk factors including anthropometrical (all P ≤ 0.005), body composition (all P ≤ 0.038), glucose metabolism (all P ≤ 0.029), lipid profile (all P < 0.035), liver (all P ≤ 0.011), and pro-inflammatory biomarkers (all P ≤ 0.030). No associations of serum 25(OH)D concentrations were found with pro-inflammatory markers (all P ≥ 0.104), omega-6 and omega-3 oxylipins, nor eCBs concentrations or their analogs (all P ≥ 0.05). CONCLUSION: The present findings support the idea that 25(OH)D could be a useful predictor of CVD risk in young individuals.

BACKGROUND AND AIMS: Accomplishing a high day-to-day reproducibility is important to detect changes in resting metabolic rate (RMR) and respiratory exchange ratio (RER) that may be produced after an intervention or for monitoring patients' metabolism over time. We aimed to analyze: (i) the influence of different methods for selecting indirect calorimetry data on RMR and RER assessments; and, (ii) whether these methods influence RMR and RER day-to-day reproducibility. METHODS AND RESULTS: Twenty-eight young adults accomplished 4 consecutive RMR assessments (30-min each), using the Q-NRG (Cosmed, Rome, Italy), the Vyntus CPX (Jaeger-CareFusion, Höchberg, Germany), the Omnical (Maastricht Instruments, Maastricht, The Netherlands), and the Ultima CardiO2 (Medgraphics Corporation, St. Paul, Minnesota, USA) carts, on 2 consecutive mornings. Three types of methods were used: (i) short (periods of 5 consecutive minutes; 6-10, 11-15, 16-20, 21-25, and 26-30 min) and long time intervals (TI) methods (6-25 and 6-30 min); (ii) steady state (SSt methods); and, (iii) methods filtering the data by thresholding from the mean RMR (filtering methods). RMR and RER were similar when using different methods (except RMR for the Vyntus and RER for the Q-NRG). Conversely, using different methods impacted RMR (all P ≤ 0.037) and/or RER (P ≤ 0.009) day-to-day reproducibility in all carts. The 6-25 min and the 6-30 min long TI methods yielded more reproducible measurements for all metabolic carts. CONCLUSION: The 6-25 min and 6-30 min should be the preferred methods for selecting data, as they result in the highest day-to-day reproducibility of RMR and RER assessments.
RESUMEN
BACKGROUND: The ageing process can be influenced by energy intake and different macronutrients within the diet. The soluble form of the α-Klotho gene (called S-Klotho) is widely considered as a powerful anti-ageing biomarker. OBJECTIVE: To analyze the association of energy, dietary energy density and macronutrient intake with S-Klotho plasma levels in middle-aged sedentary adults. METHODS: A total of 72 (52.8% women) middle-aged sedentary adults (53.7 ± 5.2 years old) participated in the study. Energy and macronutrients intake (i.e. fat, carbohydrate and protein) were assessed using three non-consecutive 24-h recalls. S-Klotho plasma levels were measured in the Ethylenediaminetetraacetic acid (EDTA) plasma using a solid-phase sandwich enzyme-linked immunosorbent assay. RESULTS: No association was observed between energy, dietary energy density or macronutrient intake and S-Klotho plasma levels in men (all P≥ 0.1). We found an inverse association between energy, protein and carbohydrate intake with S-Klotho plasma levels in women (all P≤0.043), which disappeared after controlling for age, lean mass index and sedentary time. An inverse association was observed between dietary energy density and S-Klotho plasma levels in women after controlling for covariates (all P≤0.05). CONCLUSION: In summary, the present study showed an inverse association of dietary energy density with S-Klotho plasma levels in middle-aged women. In addition, our data suggest that the associations between energy and macronutrient intake could be highly dependent on lean mass and sedentary time.

BACKGROUND & AIMS: The validity of most commercially available metabolic cart is mostly unknown. Thus, we aimed to determine the accuracy, precision, within-subject reproducibility, and concordance of RMR and RER measured by four commercially available metabolic carts [Cosmed Q-NRG, Vyaire Vyntus CPX, Maastricht Instruments Omnical, and Medgraphics Ultima CardiO2]. Further, we studied whether a previously proposed simulation-based post-calorimetric calibration of cart readouts [individual calibration control evaluation (ICcE)] modify the RMR and RER reproducibility and concordance. METHODS: Three experiments simulating different RMR and RER by controlled pure gas (N2 and CO2) infusions were conducted on 5 non-consecutive days. Moreover, 30-min methanol burns were performed on 3 non-consecutive days. Lastly, the RMR and RER of 29 young non-ventilated adults (11 women; 25 ± 4 years-old; BMI: 24.1 ± 3.2 kg/m2) were assessed twice using each instrument, 24 hours apart, under standardized conditions. RESULTS: The Omnical presented the lowest measurement error for RER (Omnical = 1.7 ± 0.9%; Vyntus = 4.5 ± 2.0%; Q-NRG = 6.6 ± 1.9%; Ultima = 6.8 ± 6.5%) and EE (Omnical = 1.5 ± 0.5%; Q-NRG = 2.5 ± 1.3%; Ultima = 10.7 ± 11.0%; Vyntus = 13.8 ± 5.0%) in all in vitro experiments (controlled pure gas infusions and methanol burns). In humans, the 4 metabolic carts provided discordant RMR and RER estimations (all P < 0.001). No differences were detected in RMR within-subject reproducibility (P = 0.058; Q-NRG inter-day coefficient of variance = 3.6 ± 2.5%; Omnical = 4.8 ± 3.5%; Vyntus = 5.0 ± 5.6%; Ultima = 5.7 ± 4.6%), although the Ultima CardiO2 provided larger RER inter-day differences (4.6 ± 3.5%) than the others carts (P = 0.001; Omnical = 1.9 ± 1.7%; Vyntus = 2.1 ± 1.3%; Q-NRG = 2.4 ± 2.1%). The ICcE procedure did not modify the RMR or RER concordance and did not reduce the inter-day differences in any of the carts. CONCLUSIONS: The 4 metabolic carts provided discordant measurements of RMR and RER. Overall, the Omnical provides more accurate and precise estimations of RMR and RER than the Q-NRG, Vyntus and Ultima CardiO2, and might be considered the best for assessing RMR and RER in non-ventilated humans. Finally, our results do not support the use of an ICcE procedure.

BACKGROUND: Exercise could influence energy and macronutrient intake, which could have an important role on body composition changes in response to exercise. The present study aimed to investigate the effects of different training modalities in energy and macronutrient intake, and whether changes in energy and macronutrient intake influences changes in body composition in response to different training modalities. METHODS: A 12-week randomised controlled trial was conducted. Eighty middle-aged sedentary adults were randomised to: (i) a control group; (ii) physical activity recommendation from the World Health Organization; (iii) high-intensity interval training; and (iv) whole-body electromyostimulation training. Dietary intake was assessed using the average of three 24-h recalls. RESULTS: High-intensity interval training and whole-body electromyostimulation training groups showed lower fibre intake and higher dietary energy density. Our results showed a negative association was found between changes in energy intake and changes in lean mass index. No association was found between changes in protein intake and changes in lean mass index. CONCLUSIONS: In conclusion, we observed a higher dietary energy density and lower fibre intake in high-intensity training groups.

This study aimed to investigate the effects of different training modalities on the soluble Klotho (S-Klotho) plasma levels in sedentary middle-aged adults. A total of 74 middle-aged adults (53.4 ± 5.0 years old; 52.7% women) were enrolled in the FIT-AGEING study. We conducted a 12-week randomised controlled trial. The participants were randomly assigned to 4 different groups: (i) a control group (no exercise), (ii) a physical activity recommendation from the World Health Organization group (PAR), (iii) a high intensity interval training group (HIIT), and (iv) a high intensity interval training group adding whole-body electromyostimulation training group (HIIT-EMS). S-Klotho plasma levels, anthropometric measurements, and body composition variables were measured before and after the intervention programme. All exercise training modalities induced an increase in the S-Klotho plasma levels (all P ≤ 0.019) without statistical differences between them (all P ≥ 0.696). We found a positive association between changes in lean mass index and changes in the S-Klotho plasma levels, whereas a negative association was reported between changes in fat mass outcomes and changes in the S-Klotho plasma levels after our intervention study. In conclusion, our results suggest that the link between exercise training and the increase in S-Klotho plasma levels could be mediated by a decrease of fat mass and an increase of lean mass.

UNLABELLED: Imperforate anus represents a wide spectrum of anorectal malformations associated with urologic, neurologic and orthopedic malformations. The outcome from the various corrective measures has improved due to new surgical techniques as well as to a better understanding of the pathology. Other factors which influence the overall outcome include the degree of patient acceptance, family support as well as the ability of the health care structure to support the patient's needs on a clinical, functional and psychologic level. AIM OF THE STUDY: Assess (with the new techniques available) the quality of life in the adult patient with ARM and compare it to that experienced by a younger patient; also we wish to determine the correlation between the observed abnormalities with the functional, neurologic and urologic outcome. MATERIALS & METHODS: Sixty-six patients were subjected to PSARP (36 M; 30 F). Six presented with cloaca and 60 with ARM (23 high and 37 low). All patients underwent the same workup to include L/S MRI diagnostics, evaluation for incontinence (urinary and bowel), a urology screening, and if required, a subsequent urodynamic study with rehabilitation and/or bowel management. All answered questionnaires (AIMAR: Italian parent's association of ARM) in order to assess their satisfaction with the current health condition, with the information received and with the treatment and follow-up sessions. The patients were classified into one of two groups. Group A, totaled 33 patients (4 cloacae) with an age range between 2 and 12 years who were operated after 1995. The second, group B, was made up of 33 patients who had been surgically treated before 1995 (age range 15-41 years), had followed the study protocol and had also a neuropsychiatry consult. RESULTS: Overall fecal continence was 69% and of this number 37% were clean without constipation. Twe2nty-one patients (32%) suffered from some form of constipation. Constipation was the most common functional disorder observed in patients who have undergone PSARP. The highest incidence of constipation was found in the ARM (low type), a favorable prognostic group with 43% constipation. Patient with "high" defects and a cloaca had a lower incidence of constipation (18%). Of the 59 patients evaluated, 85% were urinary continent and 15% were incontinent. All of the incontinent patients were in the unfavorable prognostic group of malformations. Urodynamic studies showed 7 neurogenic bladders (NB) and 2 patients with a neurovescical dysfunction (NVD). Of the 50 "dry" patients. 20 had voiding disturbances due to a voiding dysfunction, in the absence of neurologic abnormalities, and presented occasional daytime or nighttime wetting. There was no correlation between the level of the anatomic defect and the urodynamic patterns in the group. Abnormal MRI findings were observed in thirty out of fifty-two patients evaluated. The MRI findings were classified as follows. Severe abnormalities: 7 patients (13%) presented with a combination of skeletal (sacral/lumbar) and spinal cord anomalies. Only spinal cord abnormalities: 12 patients (21%). Only skeletal abnormalities: 11 (19%) patients. Patients were divided into high, low and cloacal malformations. A high degree of statistical correlation was noted between the patients belonging to the cloacae and high defect groups and the abnormal MRI findings. No significant correlation was found between the low defect group and dysrafism, abnormal MRI results and the severity of the malformation. The incidence of Tethered Cord (TC) in our limited number of patients was limited in our study (9% in the high and 7% in the low defect group) when compared to the current literature. Furthermore there was no statistically conclusive evidence that TC by itself affects the urinary or fecal control in our patients. Our recommendation is nevertheless to obtain an MRI study in all patients with ARM. CONCLUSION: All patients 17 and older reported a "good quality of life". Four are married, two with children. Aclose working relationship with the medical personnel is not only necessary but is also well received by the family particularly when younger patients are involved. The adult patient easily adapts even when information is initially scarce. He quickly reaches autonomy with personalized solutions but prefers a longer follow-up time during which, specialized medical facilities will play an important role in the treatment of ARM. Our findings illustrate the importance of both global disease-specific functioning and perceived psychosocial competencies for enhancing the QL of these patients.

Gallbladder polypoid lesions are rare in the pediatric patient and sometimes represent an incidental finding. A 13 year old male was referred to the Padua Hospital Pediatric Department for an obesity. A routine abdominal ultrasound (US) detected a gallbladder polypoid lesion 6 mm in diameter, initially considered a gallbladder adenoma. Investigation did not detect any other biliary tract abnormality. After seven months, the asymptomatic patient underwent a follow-up US which revealed the disappearance of the polypoid mass. The following concerns are raised: what is the size of the polypoid mass that should be considered for surgery? How does the presence of symptoms worsen the diagnosis and lead to preferring a surgical approach (cholecystectomy) over an echographic follow-up?

The authors reports their experience on 248 patients affected by minctional disorders isolated or related to UTI (upper tract infections) and VUR (vesico-ureteral reflux). All the patients were assessed throught a predominantly non invasive diagnostic approach which included: pediatric urologic examination with aimed anamnestic and clinical freaming, functional examination of the lower urinary tract using uroflowmetry + EMG of the perineal plane muscles (UR + EMG), kidney and bladder ultrasound. This methodology has permitted a widening of the indications in the study of vesical function as well as limiting the selected cases (hight UTI, uncertain diagnosis) of mini-invasive examination, such as flow pressure study, minctional cystourethrogram (MC) and or renal scintigraphy. An MNR of the lumbo-sacral medulla (cord) and a neurological and/or neurosurgery evaluation were only carried out were there was a suspected occult neurological pathology. The clinical sintomatogy was as follows: approximately 70% of the patients suffered from partial diurnal incontinence, 42% were affected by secondary nocturnal enuresis while 58.6% suffered from recurrent UTI. In those patients with UTI, 11% (16 patients, 24 ureteral units) suffered from associated VUR while 3.5% suffered from either congenital or acquired urethral stenosis. From the urodynamic examination, we determined the presence of detrusorial instability in 158 patients (64%) and lazy bladder or vescical hypotonia in 84 patients (34%). The suggested therapy foresees the use of: hospital home-based uroriabilitation (minctional biofeedback), endoscopic therapy (sub-ureteral bulking, urethral dilatation) and corrective VUR surgery (only in those cases that did not respond to medical treatment). The percentage of total recovery in patients with detrusorial instability was 80%, the minctional biofeedback both associated and unassociated with drug therapy lead to complete recovery in 66% of patients with lazy and uncordinated bladder, wile 26% showed improvement and 7 patients (8.4%) did not respond. All the patients with VUR (24 reflux units) recovered; and endoscopic therapy and or surgery (12 reflux units) was carried out in some of this patients.

BACKGROUND/PURPOSE: Thomsen-Friedenreich cryptantigen activation (TCA) exposes neonates with necrotizing enterocolitis NEC to the risk of hemolysis after transfusion of blood products. The authors aimed to determine the prevalence of TCA in neonates with NEC and to correlate TCA with severity of disease and outcome. METHODS: One hundred four neonates with NEC were tested for TCA on admission. Patients with TCA requiring transfusion were given packed red cells, low-titer anti-T fresh frozen plasma, and washed platelets to avoid hemolysis. RESULTS: Twenty-three infants had TCA, and 96% of these had stage III disease. The incidence of TCA was significantly higher in infants with stage III disease compared with those with stage II (30% v 4%; P <.01). A total of 91% of infants with TCA required laparotomy compared with 81% of those with no activation. At laparotomy, widespread disease was more common in the TCA group (71% v 55%). TCA did not significantly increase mortality rate (TCA, 39% v no TCA, 28%); this may reflect the transfusion policy of our unit. CONCLUSIONS: Twenty-two percent of neonates with NEC referred to our unit had TCA. There is an association between TCA and advanced NEC. Screening of neonates with advanced NEC for TCA is advised to identify those at risk of hematologic complications.

OBJECTIVE: To evaluate whether critically ill children with systemic inflammatory response syndrome (SIRS) or sepsis have altered resting energy expenditure (REE) and substrate utilization. SUMMARY BACKGROUND DATA: Studies in adults with sepsis have shown increased energy expenditure and mobilization of endogenous fat. In infants and children, energy metabolism and substrate utilization during sepsis have not been characterized. METHODS: Metabolic studies were performed in 21 critically ill children with SIRS or sepsis. Twenty-one stable control children, matched for weight, were also studied. Seven patients required inotropic support and 17 received mechanical ventilation. Fifteen patients with SIRS had evidence of bacterial, fungal, or viral infection and were considered septic. Respiratory gas exchange was measured by computerized indirect calorimetry for 1 to 2 hours continuously. RESULTS: The REE of patients with SIRS or sepsis was not different from that of controls. Similarly, there were no differences in carbon dioxide production and oxygen consumption. Resting energy metabolism was not different between patients with SIRS and patients with sepsis. In addition, the presence of low platelet count or inotropic support did not affect resting energy metabolism. The median respiratory quotient of patients with SIRS or sepsis was 0.88 (range 0.75-1.12), indicating mixed utilization of fat and carbohydrate; this was not significantly different from that of controls. The Pediatric Risk of Mortality Score was not significantly correlated with REE or respiratory quotient. CONCLUSIONS: The energy requirements of children with SIRS or sepsis are not increased. Their resting metabolism is based on both carbohydrate and fat utilization. The authors speculate that these children divert the energy for growth into recovery processes.

PURPOSE: The aim of this study was to evaluate the results of surgical treatment of necrotizing enterocolitis (NEC) according to the extent of disease and to establish if resection of the ileocecal valve represents a poor prognostic factor. METHODS: The authors reviewed all cases of NEC (n = 161) treated in our hospital during the last 11 years; of these, 83 required surgical intervention. Definitions used by the authors include isolated, disease in a single intestinal segment; multifocal, disease in two or more intestinal segments; and pan-intestinal, majority of small and large bowel involved. RESULTS: Twenty-five neonates had isolated NEC, 46 neonates had multifocal NEC, and 12 had pan-intestinal involvement. Survival rate was affected by the extent of intestinal involvement, the lowest survival rate (33%) being noticed in neonates with pan-intestinal involvement. In patients with isolated NEC, postoperative complications and survival rate were not affected by the modality of operative treatment. Conversely, in patients with multifocal NEC, survival rate was higher (85%) after resection and primary anastomosis compared with enterostomy (50%; P =.03). Resection of the ileocecal valve was not associated with increased morbidity and mortality. CONCLUSIONS: (1) Resection and primary anastomosis is a valid treatment option in both isolated and multifocal NEC. (2) Neonates with NEC adapt rapidly to the loss of the ileocecal valve.

A benign neoplastic lesion of the skin originating from cystic proliferation of apocrine secretory glands is defined as an apocrine hidrocystoma or cystadenoma. The tumor usually occurs in adults as a solitary cystic lesion; it is commonly found on the periorbital region, neck, upper torso and limbs. The case presented is unusual because of the age of the patient--cystadenoma is very rare in childhood--and the localization of the lesion. From a literature review and to the best of our knowledge, a scrotal cyst has never been previously described. Surgical excision is the treatment of choice since the lesion does not tend to recur.

Vas deferens anomalies have been observed with high incidence in cystic fibrosis patients, whereas the overall incidence in the general population is estimated less than 0.05%. Vas deferens anomalies are sometimes associated with renal abnormalities and they are due to a damage occurring within the first weeks of gestational age. In other cases they can be the expression of a mild form of cystic fibrosis. The authors report on 7 patients with 10 anomalies of vas deferens: 2 patients with cystic fibrosis; 3 patients with urinary tract anomalies; 2 patients with no evidence of cystic fibrosis and without urinary tract anomalies. It is suggested that every patient presenting with vas deferens anomalies and no evidence of cystic fibrosis should be further evaluated with renal ultrasound; moreover all patients without evidence of both cystic fibrosis and renal anomalies should have genetic investigations.

The acutely painful scrotum may be due to testicular torsion, twisted testicular appendages, twisted spermatic cord or epididymitis. Most rarely it occurs as a result of a testicular trauma, orchitis, idiopathic scrotal edema, idiopathic infarction of testis and vaginalis tunica or testicular neoplasm; a spontaneous thrombosis of the spermatic vein vessels is quite unusual. A rare case of thrombosis of a dilated pampiniform plexus which occurred in a 6 year-old child is reported and its clinical presentation, diagnosis and treatment is discussed. The difficulty in making such a diagnosis is stressed since thrombosis of the spermatic vein is quite a rare entity; a conservative approach is suggested as a treatment of choice whenever a definite diagnosis is made, otherwise surgical intervention (ligation of the spermatic vein, if necessary) is required in order to rule out any other urologic emergency.

BACKGROUND: Meconium ileus (MI) is a form of neonatal intestinal obstruction due to an abnormal thickened meconium within the terminal ileum. The aim of this retrospective paper is to review our experience with neonates affected from MI treated at our institute over a twenty year period. METHODS: This report deals with 23 neonates with MI: 14 newborns had uncomplicated MI due to obstruction of the terminal ileum with meconium pellets, while 9 presented with complications (intestinal atresia, volvulus, pseudocyst, peritonitis). RESULTS: A water soluble contrast enema (Gastrografin) was attempted in 12 cases with a success rate of 7/12 (58%). The remaining sixteen neonates underwent laparotomy, with 4 treated by resection and primary anastomosis, 7 by enterostomy (chimney or double-barrelled) and 5 managed with T-tube enterostomy. Survival rate was 93% in uncomplicated MI and 67% in complicated forms. CONCLUSIONS: On the basis of personal experience the authors suggest that the treatment of choice for uncomplicated MI is Gastrografin enema, with T-tube enterostomy to be reserved for enema failure. The surgical treatment of the complicated forms depends on the intra-abdominal findings; nowadays chimney or double barrelled enterostomy is to be reserved in cases where peritonitis, late diagnosis, prematurity or associated anomalies complicate the disease.

Congenital mesoblastic nephroma is a relatively rare infantile renal tumor. It comprises 3-6% of renal masses in childhood and 50% during the neonatal period. Most mesoblastic nephroma occur in the newborn period, with 80% of the cases being reported within the first month of life. Macroscopically the tumor is composed of a solid mass of different sizes tending to invade the surrounding structures and renal parenchyma. The authors report a case of cystic mesoblastic nephroma of the cellular subtype, with diffuse areas of hemorrhage and necrosis. The tumor was treated by surgical excision with radical nephrectomy and the child is doing well 4 years after the operation.

The assessment of energy expenditure is valuable for the management of children with various conditions such as obesity and failure to thrive. Total daily energy expenditure (TDEE) includes resting energy expenditure (REE), energy expenditure during physical activity, dietary thermogenesis and growth. TDEE can be assessed by using the double-labelled water technique, but it has complex pitfalls and potential sources of errors and is impractical for everyday use. As REE is a substantial part of TDEE (65%-70%) and computerised indirect calorimeters have become recently available, this non-invasive, relatively cheap and easy to use technique is valuable for the assessment of short-term changes in energy metabolism. This can be used to assess REE of children with inborn errors of metabolism, whilst well and during episodes of metabolic decompensation and therefore to accurately determine energy intake.
