Differences in thyroid function between small for gestational age and those with appropriate weight for gestational age. Is thyroid function normal in small for gestational age newborns?

INTRODUCTION: Several studies conclude that small for gestational age (SGA) children have a higher number of comorbidities, as well as a different hormonal profile compared to those with appropriate weight for gestational age (AGA). Thyroid hormones play an important role in growth and neurocognitive development. Thyroid function in SGA children is still not completely known. OBJECTIVES: To compare the thyroid function of SGA children during the first 2 years of life with that in publications on thyroid function in other groups of infants, such as AGA and premature children, using the same methodology. METHODS: A cohort of 38 SGA children was obtained, in which the thyrotropin (TSH) values in blood were measured at different points in the development of the SGA child. The results were compared with a population of AGA children from Zaragoza and a population of premature children from Barcelona by comparing the means using a 2-tailed test. RESULTS: A statistically significant difference (P < 0.05) was observed between the SGA children in our study and the AGA children older than 6 months, but not between the SGA children of the study and the population of premature infants. CONCLUSIONS: SGA children have higher TSH values compared to AGA children older than 6 months. Therefore, it seems reasonable to establish a screening and a follow-up protocol in those SGA with high risk to develop thyroid dysfunction.

Extraintestinal Manifestations in Patients with Inflammatory Bowel Disease: Study Based on the ENEIDA Registry.

BACKGROUND: Patients with inflammatory bowel disease (IBD) may present extraintestinal manifestations (EIMs) that affect the joints, skin, eyes, and hepatobiliary area, among others. AIMS: Our aim was to analyse the prevalence and characteristics of EIMs in patients with IBD and to identify the possible risk factors associated with the development of EIMs in the largest series published to date. METHODS: Observational, cross-sectional study including patients from the Spanish ENEIDA registry promoted by GETECCU. We retrospectively identified all cases of EIMs in the ENEIDA registry until January 2018. RESULTS: The study included 31,077 patients, 5779 of whom had at least one EIM (global prevalence 19%; 95% CI 18.2-19.0). Among the different types of EIMs, rheumatic manifestations had a prevalence of 13% (95% CI 12.9-13.7; 63% of EIMs), with a prevalence of 5% (95% CI 4.7-5.2) for mucocutaneous manifestations, 2.1% (95% CI 1.9-2.2) for ocular manifestations, and 0.7% (95% CI 0.6-0.8) for hepatobiliary manifestations. The multivariable analysis showed that the type of IBD (Crohn's disease, p < 0.001), gender (female, p < 0.001), the need for an immunomodulator (p < 0.001) or biologic drugs (p < 0.001), a previous family history of IBD (p < 0.001), and an extensive location of IBD (p < 0.001) were risk factors for the presence of EIMs. CONCLUSIONS: One-fifth of patients with IBD may have associated EIMs, with rheumatic manifestations as the most frequent (> 60% of EIMs). Female patients with severe Crohn's disease represent the group with the highest risk of developing EIMs. These patients should therefore be specially monitored and referred to the corresponding specialist when suggestive symptoms appear.

[Impact of the incorporation of a nurse in an inflammatory bowel disease unit]. / Impacto de la incorporación de la enfermera a una unidad de enfermedad inflamatoria intestinal.

INTRODUCTION: Multidisciplinary units are needed because of the growing complexity and volume of patients with inflammatory bowel disease (IBD). OBJECTIVES: To evaluate the healthcare, economic and research impact of incorporating a nurse into the IBD unit of the Puerta de Hierro Majadahonda University Hospital. METHODS: We prospectively recorded the activity carried out by the nurse of the IBD unit from March 2010 to December 2014. RESULTS: During this period, healthcare demand progressively increased, with 1,558 patients being attended by our unit. The healthcare provided by the nurse included 5,293 electronic mails and 678 telephone calls. We estimated that this activity represented a saving of 3,504 in-person medical consultations and 852 accident and emergency department visits. Other activities consisted of monitoring treatments with biological and non-biological agents (8,371 laboratory tests), extraction of 342 blood samples, follow-up of 1047 diagnostic tests and consultations with other medical specialties, health education in self-administration of drugs in 114 patients, the performance of 158 granulocyte apheresis procedures, and participation in 25 research projects. CONCLUSION: The incorporation of a specialised nurse in an IBD unit had major economic, healthcare and research benefits.

Impact of endoscopic monitoring in postoperative Crohn's disease patients already receiving pharmacological prevention of recurrence.

BACKGROUND: Current guidelines address the initiation of treatment to prevent postoperative recurrence (PR) after ileo-cecal resection in Crohn's disease (CD), but appropriate management of postoperative CD patients who are already receiving treatment to prevent PR is yet to be defined. Usefulness of endoscopic monitoring in this scenario remains uncertain. AIMS: To evaluate the usefulness of endoscopy-based management of postoperative CD patients who are already under pharmacological prevention of PR. METHODS: Retrospective review of clinical outcome of all CD patients with ileo-cecal resection who underwent postoperative colonoscopy between 2004 and 2013 at our centre. Postoperative endoscopic findings were classified as no endoscopic recurrence (Rutgeerts i0-i1) or endoscopic recurrence (Rutgeerts i2-i4). Patients with endoscopic recurrence were classified as "endoscopy-based management (EBM)" if treatment step-up after endoscopy, or "non EBM (N-EBM)". Clinical recurrence was considered if re-operation, CD related hospitalization or treatment change. Time until clinical recurrence or the end of the follow up was considered. RESULTS: One hundred sixty six patients initially identified. One hundred twenty nine (77%) under pharmacological prevention of PR at the time of colonoscopy were analyzed: 34% were receiving aminosalicylates, 50% thiopurines, 11% anti-TNF, 5% combo. Colonoscopy showed endoscopic recurrence in 57% of patients; those with N-EBM were more likely to have clinical recurrence than patients with EBM along the follow up (p = 0.01). Conclussions: Endoscopic monitoring could be useful in postoperative CD patients also in patients already receiving pharmacological treatment to prevent PR.

Mucosal healing in Crohn's disease: relevance and controversies in real life clinical practice.

Mucosal healing is a recent and emerging concept in Crohn's disease management that has been associated to a good prognosis and therefore it has been also proposed to be a clinically relevant therapeutic endpoint. On the other hand, there are many controversial aspects about this concept, and some clinically relevant difficulties that may preclude clinicians from moving this concept from clinical trials to clinical practice in many cases. This review is focused on both aspects of mucosal healing in day-to-day real life clinical practice.

Antioxidants and ecto-5'-nucleotidase are not involved in the training-induced cardioprotection against ischaemia-reperfusion injury.

Isolated Langendorff-perfused hearts from sedentary and prolonged (24 weeks) treadmill-trained rats were subjected to 30 min of normoxic perfusion either alone or followed by 20 min of global ischaemia, or by 20 min of global ischaemia and 15 min of normoxic reperfusion. Pre-ischaemic values of antioxidant enzyme activities and ecto-5'-nucleotidase activity were not different in sedentary and trained hearts but a 5-fold increase of 72-kDa heat shock protein (HSP72) levels was detected in trained myocardium. After ischaemia and reperfusion (I/R), metabolic recovery was better in trained than in sedentary hearts as indicated by higher ATP and creatine phosphate levels. However, antioxidant enzymatic activities, glutathione reductase, and total and mitochondrial superoxide dismutase decreased in trained rats after I/R, whereas they remained unchanged in the sedentary ones. Ecto-5'-nucleotidase activity was modified by I/R in sedentary as well as in trained hearts while HSP72 content did not change. Ecto-5'-nucleotidase activity and HSP72 content increased in parallel by the 30-min perfusion period. In conclusion, the cardioprotection induced by long-term training could be mediated by the exercise-induced increase in HSP72 levels and is not related to enhanced antioxidant systems or ecto-5'-NT activity.

Effects of prolonged stanozolol treatment on antioxidant enzyme activities, oxidative stress markers, and heat shock protein HSP72 levels in rat liver.

The abuse of anabolic-androgenic steroids (AAS) to enhance physical performance is widespread in sport communities despite their reported side effects. Since the biochemical bases for the hepatotoxic effects of these compounds are largely unknown, this investigation was aimed at testing whether prolonged (8 weeks) treatment with high doses (2 mg kg(-1) body weight; 5 d wk(-1)) of stanozolol (ST), either alone or in conjunction with treadmill-exercise training, induced changes in oxidative stress biomarker levels and antioxidant defence systems in rat liver. After ST oral administration, the mean values of serum parameters related to hepatic function were within normal ranges. No changes in protein carbonyl content and in the reduced to oxidized glutathione (GSH/GSSG) ratio were detected in liver homogenates of ST-treated rats, whereas thiobarbituric acid-reactive substances (TBARS) levels resulted increased (P<0.05). Total superoxide dismutase (SOD), catalase (CAT), and glutathione peroxidase (GPX) activities were higher (P<0.05) in the liver of treated rats but mitochondrial SOD and glutathione reductase (GR) activities, and the 72 kDa heat shock protein (HSP72) level were not modified. Chronic exercise alone did not change any of the above parameters except for a remarkable enhancement of HSP72 expression; in no case training modified the effects of ST treatment. The present data show that 8 wk ingestion of ST, either with or without concurrent exercise training, can induce oxidative stress in rat liver despite the up-regulation of enzymatic antioxidant activities.
