The effect of an emergency department clinical “triggers” program based on abnormal vital signs

AbstractObjectiveTo determine the effect of a clinical triggers program in the Emergency Department (ED) setting that utilized predetermined abnormal vital signs to activate a rapid assessment by an emergency physician led multidisciplinary team.MethodsA retrospective, separate sample, pre-post intervention study following implementation of an ED triggers program. Abnormal vital sign criteria that warranted a trigger response included: heart rate <40 or >130 beats/min, respiratory rate <8 or >30 respirations/min, systolic blood pressure <90 mm Hg, or oxygen saturation <90% on room air. The primary outcome investigated was time to physician evaluation with secondary outcomes being the time to disposition decision and time to first critical therapeutic intervention.ResultsThe median time to physician evaluation was reduced by 25% from 28 min to 21 min (P<0.05). The median time to disposition decision was decreased by 12% from 154 minutes to 135 minutes (P<0.05). The median time to first intervention was 46 min and 43 min (P=0.33) in the before and after groups, which did not represent a statistically significant difference.ConclusionsIn our model, the implementation of an ED triggers program resulted in a modest decreased time to physician evaluation and disposition decision but not time to intervention

Malignant Acute Disseminated Encephalomyelitis (ADEM) Presenting as a Stroke Alert: A Case Report.

Acute disseminated encephalomyelitis (ADEM) is a rare illness. Generally characterized by encephalopathy and non-specific, heterogeneous neurological deficits depending on the location of the demyelinated lesions, ADEM is considered a clinical diagnosis with radiological findings that may or may not have supportive features based on the temporal relationship of an inciting factor and symptom onset. Even rarer, hyperacute or malignant ADEM can be defined by rapid symptom onset followed by catastrophic brain edema and its sequelae. We present a case of a patient who presented with an acute stroke with activation of a rapid sequence care pathway (stroke alert protocol) to mobilize resources that could expedite his care to determine eligibility for thrombolysis. ADEM was the definitive diagnosis with a subsequent rapid and treatment-refractory decline

Discrepant Prevalence and Incidence of Leishmania Infection between Two Neighboring Villages in Central Mali Based on Leishmanin Skin Test Surveys

Leishmaniasis is a vector-borne disease transmitted to humans by the bite of an infected sand fly. Leishmaniasis is present in more than 88 countries and affects more than 12 million people. Depending on the species of Leishmania, the host can develop cutaneous leishmaniasis (CL), which is characterized by skin ulcers in uncovered parts of the body or a more severe form, visceral leishmaniasis, which affects the liver and spleen and is fatal if not treated. This study aims to establish the past and present infection with Leishmania parasites in two villages where recent cases have been diagnosed by the dermatology center (CNAM) in Bamako. This was achieved using a Leishmania-specific skin test that was administered annually to permanent residents of Kemena and Sougoula villages from 2006 to 2008. The results show that transmission of Leishmania is active and stable in these two villages. Moreover, despite sharing similar cultural and environmental features, the individuals from Kemena presented three times the risk of Leishmania infection compared with those from Sougoula. Our findings raise awareness of the continued presence of CL in Mali

African Bush Viper Envenomation: A Case Report

Atheris squamigera envenomation is an infrequently documented occurrence in the United States (US). Cases of envenomation may induce severe coagulopathies, renal failure, and potentially life-threatening hemorrhage. Currently, there are no antivenoms specific to the Atheris genus, but there have been documented cases of the use of antivenoms for other species. A 26-year-old man presented to the emergency department (ED) complaining of swelling and discomfort in his left foot after being bitten by an Atheris squamigera that he kept as a pet.After performing a physical exam, it was noted that the patient’s envenomation was likely mild. Throughout his hospital stay, he developed lab abnormalities, most notably an elevated D-dimer and low fibrinogen. His clinical symptoms improved after a short stay, and he did not require antivenom treatment. This case highlights a rare, but potentially life-threatening envenomation that may be encountered in the US due to the continued practice of exotic pet ownership and sales. Moreover, procurement of antivenom for non-native species poses a unique challenge to US physicians responsible for treating these patients

The quality of surgical pathology care for men undergoing radical prostatectomy in the U.S.

BACKGROUND. The authors assessed adherence with the College of American Pathologists (CAP) radical prostatectomy (RP) practice protocol in a national sample of men who underwent RP for early-stage prostate cancer. METHODS. Using the National Cancer Data Base, the authors identified a nationally representative sample of 1240 men (unweighted) who underwent RP. For each patient, local cancer registrars performed an explicit medical record review to assess patient-level compliance with surgical pathology report documentation of 7 morphologic criteria (ie, quality indicators). Applying the CAP prognostic factor classification framework, composite measures and all-or-none measures of quality indicator compliance were calculated for the following analytic categories: 1) a strict subset of CAP category I prognostic factors (3 indicators), 2) a broad subset of CAP category I factors (6 indicators), and 3) the full set of 7 indicators. RESULTS. Among a weighted sample of 24,420 patients who underwent RP, compliance with documentation of the CAP category I factors varied from 54% (95% confidence interval [95% CI], 50–58%) for pathologic tumor, lymph node, metastases classification (according to the American Joint Committee on Cancer staging system) to 97% (95% CI, 96–99%) for Gleason score. In composite, RP pathology reports contained 83% (95% CI, 81–84%), 85% (95% CI, 84–87%), and 79% (95% CI, 78–80%) of the recommended data elements measured by the strict CAP category I subset, the broad CAP category I subset, and the full set of 7 indicators, respectively. In contrast to the generally higher composite scores, only 52% (95% CI, 48–56%) and 41% (95% CI, 37–45%) of men who underwent RP had complete documentation in their pathology reports for the strict and broad CAP category I subsets, respectively. CONCLUSIONS. RP surgical pathology reports contained most of the recommended data elements; however, the frequent absence of pathologic stage provides an opportunity for quality improvement.

Activation of a non-neuronal cholinergic system in visceral white adipose tissue of obese mice and humans

Background and objectives: Since white adipose tissue (WAT) lacks parasympathetic cholinergic innervation, the source of the acetylcholine (ACh) acting on white adipocyte cholinergic receptors is unknown. This study was designed to identify ACh-producing cells in mouse and human visceral WAT and to determine whether a non-neuronal cholinergic system becomes activated in obese inflamed WAT. Methods: Mouse epididymal WAT (eWAT) and human omental fat were studied in normal and obese subjects. The expression of the key molecules involved in cholinergic signaling was evaluated by qRT-PCR and western blotting whereas their tissue distribution and cellular localization were investigated by immunohistochemistry, confocal microscopy and in situ hybridization. ACh levels were measured by liquid chromatography/tandem mass spectrometry. The cellular effects of ACh were assessed in cultured human multipotent adipose-derived stem cell (hMADS) adipocytes. Results: In mouse eWAT, diet-induced obesity modulated the expression of key cholinergic molecular components and, especially, raised the expression of choline acetyltransferase (ChAT), the ACh-synthesizing enzyme, which was chiefly detected in interstitial macrophages, in macrophages forming crown-like structures (CLSs), and in multinucleated giant cells (MGCs). The stromal vascular fraction of obese mouse eWAT contained significantly higher ACh and choline levels than that of control mice. ChAT was undetectable in omental fat from healthy subjects, whereas it was expressed in a number of interstitial macrophages, CLSs, and MGCs from some obese individuals. In hMADS adipocytes stressed with tumor necrosis factor a, ACh, alone or combined with rivastigmine, significantly blunted monocyte chemoattractant protein 1 and interleukin 6 expression, it partially but significantly, restored adiponectin and GLUT4 expression, and promoted glucose uptake. Conclusions: In mouse and human visceral WAT, obesity induces activation of a macrophage-dependent non-neuronal cholinergic system that is capable of exerting anti-inflammatory and insulin-sensitizing effects on white adipocytes.
