Background: Zinc is an essential micronutrient for human beings and its deficiency affects their normal growth and development. Objective: The main aim was to evaluate the effect of two doses of zinc supplementation (ZS) on the nutritional status in chronic kidney disease (CKD) children. Methods: A randomized-trial multicentric study was conducted in 48 CKD (23 females) patients under 18-years-old, for a year. At random, participants took 30 or 15 mg/day of ZS, respectively. Anthropometric measurements and biochemical analysis were performed. Hypozincemia was determined by serum zinc concentration (SZC) using atomic absorption spectrophotometry. The positive or negative change in patients’ body mass index (BMI) Z-score, serum albumin, zinc and C-reactive protein (CRP) levels were used to evaluate the effect of ZS. Results: Mean SZC was normal before and after ZS. Despite ZS, there were no significant changes in serum albumin, zinc and CRP levels. A positive and significant association was observed between SZC and serum albumin before (p = 0.000) and after (p = 0.007) ZS. In both groups of ZS, there was a small but positive and significant change in body mass and normalization in BMI Z-score, hypoalbuminemia, hypozincemia and high CRP, especially with 30 mg/day of ZS. Conclusions: Zinc supplementation may be beneficial for nutritional status in children and adolescents with CKD.
Introduction: care overload, aging of population, and increased chronic diseases lead to increased referrals from primary care, which may sometimes overload the health system. Thus, different interventions have been carried out attempting to improve these aspects.Objectives: to assess the most frequent causes of consultation of general physicians, both in joint consultations and clinical sessions held jointly with specialist consultant in primary care, in the urban and rural setting, and the influence on referrals to first consultations of gastroenterology.Material and methods: a mainly training type of intervention was carried out, consisting of regular meetings in both urban and rural primary care center, to perform joint consultations and clinical sessions on patients and topics related to the specialty of gastroenterology. The intervention period (divided in two subperiods) was compared with a control period.Results: most reasons for consultation were those corresponding to lower gastrointestinal tract, followed by liver disease and upper gastrointestinal tract. Significant differences were only found in distribution of diagnoses between the two centers in joint consultations. There was a relative (percent) decrease in referrals at the global level in both subperiods, only significant in the first (51.45 %), as well as in rural setting (45.24 %).Conclusion: common consultations motifs were similar in urban and rural settings, with some relevance of lower gastrointestinal tract disease. Most of them can be solved at primary care, with the help of consultant specialist. There is impact on referrals to the outpatient first consultations of gastroenterology, mainly in rural setting.
We present the electromyographic (EMG) results ten years after open decompression of the median nerve at the wrist and compare them with the clinical and functional outcomes as judged by Levine's Questionnaire. This retrospective study evaluated 115 patients who had undergone carpal tunnel decompression at a mean of 10.47 years (9.24 to 11.36) previously. A positive EMG diagnosis was found in 77 patients (67%), including those who were asymptomatic at ten years.It is necessary to include both clinical and functional results as well as electromyographic testing in the long-term evaluation of patients who have undergone carpal tunnel decompression particularly in those in whom revision surgery is being considered. In doubtful cases or when there are differing outcomes, self-administered scales such as Levine's Questionnaire should prevail over EMG results when deciding on the need for revision surgery.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
