RESUMEN

Science is under attack and scientists are becoming more involved in efforts to defend it. The rise in science advocacy raises important questions regarding how science mobilization can both defend science and promote its use for the public good while also including the communities that benefit from science. This article begins with a discussion of the relevance of science advocacy. It then reviews research pointing to how scientists can sustain, diversify, and increase the political impact of their mobilization. Scientists, we argue, can build and maintain politically impactful coalitions by engaging with and addressing social group differences and diversity instead of suppressing them. The article concludes with a reflection on how the study of science-related mobilization would benefit from further research.

RESUMEN

A 59-year-old male with past medical history significant for non-Hodgkin's lymphoma status after chemotherapy presented with acute onset of neck pain, odynophagia, and dysphagia associated with subjective fever, chills, and dyspnea. Physical findings included a temperature of 38.4°C, hypertension, and tachycardia. Patient was found to have anterior neck tenderness. Laboratory evaluation revealed neutropenia. The patient was started on empiric antibacterial and antiviral therapy and continued on home prophylactic antifungal treatment. Thyroid function tests revealed overt hyperthyroidism. A thyroid ultrasound showed heterogeneous echotexture without discrete nodules. Subacute thyroiditis was treated with methylprednisolone, metoprolol, and opiate analgesics. Patient's antibacterial, antifungal, and antiviral treatments were broadened. A fine needle aspiration was not conducted. The patient's condition deteriorated rapidly over his brief hospital course and he expired. Autopsy showed fungal thyroiditis secondary to disseminated invasive Aspergillus. This report describes the presentation of fungal thyroiditis secondary to disseminated invasive Aspergillus originating from the respiratory tract. The authors review the diagnostic challenges, pathophysiology, and treatment of this condition.

RESUMEN

BACKGROUND: Trauma during pregnancy places two lives at risk. Knowledge of risk factors for trauma during pregnancy may improve outcomes. METHODS: We reviewed the charts of 188 such patients admitted to a Level I trauma center from 1996 to 2004. A comparison was made of injury severity and outcome from a cohort of nonpregnant female trauma patients selected with a similar temporal occurrence and age range. RESULTS: Motor vehicle collisions comprised 160 cases, 67 using a restraint device. Of 84 patients tested, 45 tested positive for intoxicants, 16 positive for 2 or more intoxicants. A significant trend toward less testing through the study period was observed (p = 0.0002). Injury severity was assessed by Revised Trauma Score (RTS). RTS <11 or admission to operating room or intensive care units (OR/ICU) classified patients as severely injured. The six maternal fatalities had an RTS <11 or OR/ICU disposition. Fetal outcomes included 155 live in utero, 18 live births, and 15 fatalities correlating with injury severity by either criteria (p < 0.0001). Of the fetal fatalities, 7 occurred with RTS = 12, but only 3 fatalities occurred in the 147 cases not admitted to OR/ICU. Gestational age correlated (p < 0.0001) with fetal outcomes. The 18 live births had mean gestational ages of 35 +/- 4 weeks as compared with fetal fatalities at 20 +/- 9 weeks, and fetuses alive in utero at 22 +/- 9 weeks gestation. Coagulation tests prothrombin time (PT), international normalized ratio (INR) (both p < 0.008), and partial thromboplastin time (PTT) (p < 0.0001) correlated with maternal outcome. A matched cohort of nonpregnancy trauma cases during the same time frame indicated that, despite a significantly higher percentage of severely injured patients, fewer fatalities occurred. This might reflect a greater risk for the pregnant trauma patient. CONCLUSIONS: This study of trauma in pregnancy cases revealed a high percentage with risk behaviors. There was a significant trend toward less intoxicant testing in recent years. Coagulation tests were the most predictive of outcomes. Lower gestational age correlated with fetal demise.

RESUMEN

The authors evaluated the correlation of post-cardiopulmonary bypass surgery bleeding, measured as 24-hour chest tube output/kilogram body weight, with platelet function tests using glass bead adhesion and Thrombelastograph Platelet Mapping (Haemoscope Corporation, Niles, Ill); coagulation tests; patient characteristics; surgery parameters; and visual assessment of surgical field bleeding before closure as not bleeding (code 1), oozing (code 2), and excessive bleeding (code 3). All platelet function and coagulation tests indicated significant dysfunction 15 minutes after protamine neutralization of heparin. With the exception of glass bead adherence, these assays indicated poor recovery of function 1 hour postoperatively. By multiple regression, the most significant predictors of postoperative bleeding were a low body mass index (BMI) (P < 0.0001), lowest core body temperature (P = 0.0006), and cross clamp time (P < 0.0001). Low core temperature was significantly (P < 0.0001) correlated with cross clamp time, which the authors believe is the most likely cause of coagulation and platelet dysfunction. None of the platelet function tests significantly correlated with bleeding. Looking at the highest quartile of chest tube output patients (n = 19) versus the upper and lower 50th percentile of coagulation and platelet function, bleeding could be explained for 11 patients by BMI plus surgery parameters along with coagulation and/or platelet dysfunction. In three cases without negative surgery parameters, coagulation dysfunction was observed. The remaining five cases did not give a clear indication of which parameters were primarily responsible for the bleeding.
