OBJECTIVE: To assess the differences in the blood concentration levels of the thyroid stimulating hormone and their possible use as an indicator of iodine sufficiency, in a sample of Mexican newborns. MATERIAL AND METHODS: A cross-sectional study was conducted from September 1999 to August 2000, among 25,427 Mexican newborns in the Ministry of Health clinics from 5 states. A total of 8,095 heel-prick and 17,332 umbilical cord blood samples were analyzed. Blood samples were collected in filter paper and processed by enzyme-linked immunosorbent assay. The Mann-Whitney U test and the Kruskal-Wallis test were used for statistical analyses. RESULTS: Hyperthyrotropinemia was found in 9.95% of heel samples and in 24.27% of umbilical cord samples (TSH > 5 microUl/ml). CONCLUSIONS: The percentage of hyperthyrotropinemia observed in this study was higher than that expected in a population with sufficient iodine intake; these findings could be due to poor maternal iodine intake. 相似文献

For some time, anomalous serological reactions have been observed when the same anti-Swa sera are tested against red cells from different individuals reported as Sw(a+). A comparative collaborative study using the same collection of Sw(a+) cells and anti-Swa sera was undertaken by 4 reference laboratories, and it was found that Swa represents a heterogeneous group of antigens that can be subdivided into two categories. Both categories, Sw(a+) 700:41 and Sw(a+) 700:-41, were shown to be inherited. 相似文献

BACKGROUND/AIMS: The aim of this prospective study was to characterize gastric myoelectrical activity in patients with Roux-en-Y reconstruction after previous Billroth gastrectomy. METHODOLOGY: Thirteen patients entered the study (6 men and 7 women, aged 35-57). The mean time from Roux-en-Y reconstruction to electrogastrography (EGG) recording was 5 years. Surface cutaneous EGG was recorded using a Digitrapper EGG in the morning both fasting and after a standard solid test meal. All patients assessed their dyspeptic symptoms at the time of EGG in a semi-quantitative subjective scale. RESULTS: EGG was abnormal in all studied patients (but one postprandial recording). Dyspepsia was not meal-related and was not more severe in Helicobacter pylori positive patients. There was a significant negative correlation between time from Roux-en-Y reconstruction to EGG recording and bradygastria percent activity, both fasted and postprandial (r = -0.576; p = 0.0022). There was an inverse trend between severity of dyspepsia and normal slow-wave rhythm percent activity. Older patients tended to have more severe dyspepsia. CONCLUSIONS: The results of this study suggest that abnormal EGG recording is associated with dyspepsia in patients after Roux-en-Y reconstruction. 相似文献

Noradrenergic deficits have been described in the hippocampus and the frontal cortex of Alzheimer's disease brains, which are secondary to locus coeruleus degeneration. Locus coeruleus is the brain stem nucleus responsible for synthesis of noradrenaline and from where all noradrenergic neurons project. In addition, it has been suggested that noradrenaline might play a role in modulating inflammatory responses in Alzheimer's disease. In this study we aimed to investigate the effect of various agonists and antagonists for adrenergic receptors on amyloid precursor protein processing. Among them, we found that prazosin, an α1-adrenoceptor antagonist, was able to reduce the generation of amyloid β in N2a cells. Treatment of transgenic APP23 mice with prazosin prevented memory deficits over time. Although prazosin did not influence amyloid plaque load, it induced astrocytic proliferation and increased the release of apolipoprotein E and anti-inflammatory cytokines. These findings suggest that chronic treatment with prazosin leads to an anti-inflammatory response with potential beneficial effects on cognitive performance. 相似文献

The pandemic caused by severe acute respiratory syndrome coronavirus 2 (SARS‐Cov‐2) has led to the elaboration of multiple studies to increase knowledge and understanding, hence, having the ability to accomplish an adequate and timely diagnosis and give an optimal treatment according to the patient's condition. The clinical manifestations of COVID‐19 pose a series of challenges both in understanding and delimiting the disease secondary to the SARS‐CoV‐2 infection. This is due to the fact that the main axis of this disease is the endothelial compromise and the production of a “cytokine storm,” triggering multiple organ failure and death. Given that a complete understanding of its pathophysiology and clinical behavior has not yet been achieved, we wondered if coinfection with other respiratory viruses modifies its performance and outcomes described so far. A literature search was performed, obtaining 68 articles, of which 25 were analyzed. The analysis showed us that there is a high variety both in the types of associated infections and in the clinical behavior of patients and their outcomes. Therefore, we consider that the search for other infections should be performed exhaustively, especially in those cases that may be susceptible to treatment such as Influenza A, human immunodeficiency virus, or bacterial infections. As well as optimize the analysis of these cases and establish if there are characteristics that allow establishing the possibility of carrying an additional infection to that of SARS‐CoV‐2 and the implications for the management and prognosis of the patient. 相似文献
