TL;DR: Routine use of this assay should be considered because it may allow earlier discharge of the normocalcemic patient and earlier identification of patients requiring treatment of postthyroidectomy hypocalcemia.
Abstract: BACKGROUND: Monitoring for hypocalcemia after thyroidectomy, using only symptoms and serum calcium levels, can delay the discharge of patients who will remain normocalcemic and can delay the treatment of hypocalcemic patients. STUDY DESIGN: We conducted a systematic search for articles describing use of parathyroid hormone (PTH) assay, checked within hours of completing thyroidectomy, to predict postoperative symptomatic hypocalcemia. Studies were excluded if all patients were treated with postoperative calcium, or if early PTH values were used to alter management of the patient. Individual patient data (perioperative PTH and calcium levels, development of hypocalcemia) were obtained for 457 patients from the corresponding authors of 9 studies and pooled to yield the following results. RESULTS: PTH, checked at three time periods after removal of the thyroid gland (0 to 20 minutes, 1 to 2 hours, and 6 hours), was substantially lower in patients who became hypocalcemic compared with those who remained normocalcemic. The accuracy of PTH in determining hypocalcemia increased with time and was excellent when checked 1 to 6 hours postoperatively. A single PTH threshold (65% decrease compared with preoperative level), checked 6 hours after completing thyroidectomy, had a sensitivity of 96.4% and specificity of 91.4% in detecting postoperative hypocalcemia. CONCLUSIONS: PTH assay, when checked 1 to 6 hours after thyroidectomy, has excellent accuracy in determining which patients will become symptomatically hypocalcemic. Routine use of this assay should be considered because it may allow earlier discharge of the normocalcemic patient and earlier identification of patients requiring treatment of postthyroidectomy hypocalcemia.

TL;DR: The mechanisms linking defective MQC to organelle dysfunction in the context of cardiac ageing are discussed and how these pathways might be targeted for the prevention and treatment of age-related heart dysfunction are considered.
Abstract: Cardiovascular disease is the leading cause of morbidity and mortality worldwide. Advancing age is a major risk factor for developing cardiovascular disease because of the lifelong exposure to cardiovascular risk factors and specific alterations affecting the heart and the vasculature during ageing. Indeed, the ageing heart is characterized by structural and functional changes that are caused by alterations in fundamental cardiomyocyte functions. In particular, the myocardium is heavily dependent on mitochondrial oxidative metabolism and is especially susceptible to mitochondrial dysfunction. Indeed, primary alterations in mitochondrial function, which are subsequently amplified by defective quality control mechanisms, are considered to be major contributing factors to cardiac senescence. In this Review, we discuss the mechanisms linking defective mitochondrial quality control mechanisms (that is, proteostasis, biogenesis, dynamics, and autophagy) to organelle dysfunction in the context of cardiac ageing. We also illustrate relevant molecular pathways that might be exploited for the prevention and treatment of age-related heart dysfunction.

TL;DR: This study suggests that the short-term negative impact of exposure to air pollutants on respiratory volume and flow is limited to individuals with already impaired respiratory function.
Abstract: Adverse health effects at relatively low levels of ambient air pollution have consistently been reported in the last years. We conducted a time-series panel study of subjects with chronic obstructive pulmonary disease (COPD), asthma, and ischemic heart disease (IHD) to evaluate whether daily levels of air pollutants have a measurable impact on the lung function of adult subjects with pre-existing lung or heart diseases. Twenty-nine patients with COPD, asthma, or IHD underwent repeated lung function tests by supervised spirometry in two one-month surveys. Daily samples of coarse (PM10–2.5) and fine (PM2.5) particulate matter were collected by means of dichotomous samplers, and the dust was gravimetrically analyzed. The particulate content of selected metals (cadmium, chrome, iron, nickel, lead, platinum, vanadium, and zinc) was determined by atomic absorption spectrometry. Ambient concentrations of nitrogen dioxide (NO2), carbon monoxide (CO), ozone (O3), and sulphur dioxide (SO2) were obtained from the regional air-quality monitoring network. The relationships between concentrations of air pollutants and lung function parameters were analyzed by generalized estimating equations (GEE) for panel data. Decrements in lung function indices (FVC and/or FEV1) associated with increasing concentrations of PM2.5, NO2 and some metals (especially zinc and iron) were observed in COPD cases. Among the asthmatics, NO2 was associated with a decrease in FEV1. No association between average ambient concentrations of any air pollutant and lung function was observed among IHD cases. This study suggests that the short-term negative impact of exposure to air pollutants on respiratory volume and flow is limited to individuals with already impaired respiratory function. The fine fraction of ambient PM seems responsible for the observed effects among COPD cases, with zinc and iron having a potential role via oxidative stress. The respiratory function of the relatively young and mild asthmatics included in this study seems to worsen when ambient levels of NO2 increase.

TL;DR: The role of ZAP-70 in BCR signaling is quite distinct from its role in TCR signaling and is likely mediated by inhibition of events that terminate the signaling response.

TL;DR: In this article, the authors compared the performance and risk of 181 large banks from 15 European countries over the 1999-2004 period and evaluated the impact of alternative ownership models, together with the degree of ownership concentration, on their profitability, cost efficiency and risk.
Abstract: We compare the performance and risk of a sample of 181 large banks from 15 European countries over the 1999-2004 period and evaluate the impact of alternative ownership models, together with the degree of ownership concentration, on their profitability, cost efficiency and risk. Three main results emerge. First, after controlling for bank characteristics, country and time effects, mutual banks and government-owned banks exhibit a lower profitability than privately-owned banks, in spite of their lower costs. Second, public sector banks have poorer loan quality and higher insolvency risk than other types of banks while mutual banks have better loan quality and lower asset risk than both private and public sector banks. Finally, while ownership concentration does not significantly affect a bank's profitability, a higher ownership concentration is associated with better loan quality, lower asset risk and lower insolvency risk. These differences, along with differences in asset composition and funding mix, indicate a different financial intermediation model for the different ownership forms.
