Adverse Events Reported in Trials Assessing Manual Therapy to the Extremities: A Systematic Review.

Objective: This review aimed to describe the quality and comprehensiveness of adverse event (AE) reporting in clinical trials incorporating manual therapy (MT) as an intervention for extremity conditions using the Consolidated Standards of Reporting Trials (CONSORT)-Harms extension as the benchmark. The secondary aim was to determine whether the quality of AE reporting improved after the availability of the CONSORT reporting checklist. Design: Systematic review. Methods: A literature search was conducted using multiple databases to identify trials where MT was used to treat extremity conditions. Studies that reported AEs were identified and evaluated using the CONSORT-Harms extension. The frequency of trials reporting study AEs before and after the publication of the updated 2010 CONSORT statement was calculated, along with the categorization of how study AEs were reported. Results: Of the 55,539 studies initially identified, 220 trials met all inclusion criteria. Eighty trials (36.4%) reported AE occurrence. None of the studies that reported AEs adhered to all 10 criteria proposed by the 2010 CONSORT-Harms extension. The most commonly reported criterion was number four, which clarified how AE-related information was collected (30% of trials). The least reported criterion was number six, which describes the participant withdrawals for each arm due to AEs and the experience with the allocated treatment (1.3% of trials). The nomenclature used to describe AEs varied substantially. Fifty-nine of 76 trials (33.3%) were published after the updated CONSORT Harms-checklist was available, compared to 21 of 44 trials (46.7%) published before it was available. Conclusion: Reporting of AEs in trials investigating MT for extremity conditions is poor. Every included trial lacked adherence to all 10 criteria proposed by the CONSORT-Harms Extension. The quality and comprehensiveness of AE reporting did not improve after the most recent CONSORT update recommending AE reporting. Clinicians must obtain informed consent before performing any intervention, including MT, which requires disclosing potential risks, which could be better known with improved tracking, analyzing, and reporting of AEs. The authors recommend improved adherence to best practices for adequately tracking and reporting AEs in future MT trials.

Predicting the geographic distribution of ancient Amazonian archaeological sites with machine learning.

Amazonia has as least two major centers of ancient human social complexity, but the full geographic extents of these centers remain uncertain. Across the southern rim of Amazonia, over 1,000 earthwork sites comprised of fortified settlements, mound villages, and ditched enclosures with geometric designs known as geoglyphs have been discovered. Qualitatively distinct and densely located along the lower stretches of major river systems and the Atlantic coast are Amazonian Dark Earth sites (ADEs) with deep anthropogenic soils enriched by long-term human habitation. Models predicting the geographic extents of earthworks and ADEs can assist in their discovery and preservation and help answer questions about the full degree of indigenous landscape modifications across Amazonia. We classify earthworks versus ADEs versus other non-earthwork/non-ADE archaeological sites with multi-class machine learning algorithms using soils, climate, and distances to rivers of different types and sizes as geospatial predictors. Model testing is done with spatial cross-validation, and the best model at the optimal spatial scale of 1 km has an Area Under the Curve of 0.91. Our predictive model has led to the discovery of 13 new geoglyphs, and it pinpoints specific areas with high probabilities of undiscovered archaeological sites that are currently hidden by rainforests. The limited, albeit impressive, predicted extents of earthworks and ADEs means that other non-ADE/non-earthwork sites are expected to predominate most of Western and Northern Amazonia.

Feeling exhausted: How outpatient physical therapists perceive and manage job stressors.

PURPOSE: Burnout is identified as a workplace problem rather than a worker problem. However, it remains unclear what job stressors are associated with burnout among outpatient physical therapists. Thus, the primary objective of this study was to understand the burnout experiences of outpatient physical therapists. The secondary aim was to identify the relationship between physical therapist burnout and the work setting. METHODS: One-on-one interviews based on hermeneutics were used for qualitative analysis. Quantitative data was collected using the Maslach Burnout Inventory-Health Services Survey (MBI-HSS) and the Areas of Worklife Survey (AWS). RESULTS: Qualitative analysis found participants interpreted an increased workload with no increase in wages, loss of control, and a mismatch between organizational culture and values as the main drivers of organizational stress. Professional issues such as high debt burden, low salaries, and declining reimbursement emerged as stressors. Participants showed moderate to high emotional exhaustion per the MBI-HSS. There was a statistically significant association between emotional exhaustion and workload and control (p < 0.001). For every one-point increase in workload, emotional exhaustion increased by 6.49 while for every one-point increase in control, emotional exhaustion decreased by 4.17. CONCLUSION: Outpatient physical therapists in this study felt that increased workload with a lack of incentives and inequity, coupled with a loss of control, and a mismatch between personal and organizational values were significant job stressors. Creating awareness of outpatient physical therapist's perceived stressors may play an important role in developing strategies to diminish or prevent burnout.

Late Pleistocene pottery production and exchange: Provenance studies of hunter-gatherer wares from southern Kyushu, Japan by neutron activation analysis.

Late Pleistocene hunter-gatherers in East Asia adopted pottery, yet the ability to reconstruct circulation, mobility, and exchange has been hampered, in part, due to problematic regional geochronology. The driving forces behind pottery adoption is unclear. The purpose of this study is to test our results of the first systematic petrographic pottery sourcing from the pre-Younger Dryas by utilizing neutron activation analysis. We examine samples from the Sankauyama I site on Tanegashima Island, southern Japan, dating to the Incipient Jomon, ca. 14,000/13,500-12,800 cal BP, with a well-defined geochronology. Our NAA results corroborate with the petrographic study suggesting that pottery was mainly produced in-situ, but some vessels were transported long distances from another island. Changing from high mobility, sedentary Incipient Jomon foragers made pottery, occasionally investing in long-distance ceramic vessel transportation and exchange likely involving ocean crossing. This may be associated with a risk-buffering strategy in the context of rising sea levels and isolation of Tanegashima.

Evaluation of prehospital hydroxocobalamin use in the setting of smoke inhalation.

BACKGROUND: The indications for prehospital hydroxocobalamin are not well defined. The aim of this study was to evaluate prehospital signs and symptoms in patients who received hydroxocobalamin to improve future use. METHODS: In this retrospective study, all patients who received prehospital Hydroxocobalamin at a tertiary care burn center from December 2012 to March 2018 were reviewed. Each case was evaluated for evidence of suspected cyanide toxicity: hypotension, syncope, CNS depression/altered mentation, seizures, respiratory or cardiac arrest. A determination was made whether or not hydroxocobalamin was indicated. RESULTS: In this study, EMS providers administered hydroxocobalamin to 42 patients between December 2012 and March 2018. The majority (71%) of suspected cyanide exposures were from house fires. The most common prehospital findings were coma or depressed CNS (36%), followed by hypotension (16%) and cardiac arrest (12%). Sixty percent of patients treated with hydroxocobalamin had none of the six clinical indicators for potential cyanide toxicity. Carboxyhemoglobin and serum lactate were significantly different in patients that had a clinical indication for hydroxocobalamin compared to those who did not. CONCLUSIONS: Prehospital hydroxocobalamin was used empirically however, indications are unclear. Using defined clinical indications may provide greater clarity for providers and reduce unnecessary use of hydroxocobalamin.

Clinical outcomes in men with prostate cancer who selected active surveillance using a clinical cell cycle risk score.

Aim: To evaluate active surveillance (AS) selection, safety and durability among men with low-risk prostate cancer assessed using the clinical cell cycle risk (CCR) score, a combined clinical and molecular score. Patients & methods: Initial treatment selection (AS vs treatment) and duration of AS were evaluated for men with low-risk prostate cancer according to the CCR score and National Comprehensive Cancer Network guidelines. Adverse events included biochemical recurrence and metastasis. Results: 82.4% (547/664) of men initially selected AS (median follow-up: 2.2 years), 0.4% (2/547) of whom experienced an adverse event. Two-thirds of patients remained on AS for more than 3 years; patient choice was the most common reason for leaving AS. Conclusion: The CCR score may aid in the identification of men who can safely defer prostate cancer treatment.

Bathroom Entrapment Leading to Cardiac Arrest From Crush Syndrome.

Crush injuries have the potential to cause life-threatening systemic effects such as hyperkalemia, dysrhythmias, acute kidney injury, and renal failure. Systemic involvement is known as crush syndrome (CS) and results from tissue ischemia and muscle necrosis. This is a report of a 76-year-old female who developed a fatal dysrhythmia following release of her extremity from prolonged entrapment in bathroom safety equipment. Hyperkalemia should be presumed in any crush injury and be treated empirically and aggressively. Although tourniquet application prior to extrication is not widely recommended to prevent CS, it should be considered in prolonged extremity entrapment.

Intubation Success after Introduction of a Quality Assurance Program Using Video Laryngoscopy.

OBJECTIVE: The deployment of video laryngoscopy devices that include recording capability presents a new and unique opportunity for medical directors to review prehospital patient encounters. We sought to evaluate the effect of introducing a video laryngoscope and video quality assurance program to an air medical program on measures of intubation success including overall success, first-pass success, success within 2 attempts, and the total number of attempts. METHODS: This was a retrospective review of data collected on intubations by nurses and paramedics of the Virginia State Police Med-Flight 1 air medical program. RESULTS: After introduction of the video laryngoscope and quality assurance program, the overall intubation success improved to 100% but did not reach statistical significance (95% confidence interval [CI], -4.40 to 12.57; P = .25). First-pass success improved from 76.19% to 92.86% (CI, 1.14-33.14; P = .02), whereas the average attempts declined from 1.31 to 1.09 per patient encounter (CI, -.41 to -.03; P = .02). Success within 2 attempts was 92.86% before the intervention and 98.21% after (CI, 4.25-17.82; P = .19). CONCLUSION: Video laryngoscopy and a robust means for medical director oversight are important components of a high-performance airway management program and demonstrably improve intubation first-pass success.

Long-distance stone transport and pigment use in the earliest Middle Stone Age.

Previous research suggests that the complex symbolic, technological, and socioeconomic behaviors that typify Homo sapiens had roots in the middle Pleistocene <200,000 years ago, but data bearing on human behavioral origins are limited. We present a series of excavated Middle Stone Age sites from the Olorgesailie basin, southern Kenya, dating from ≥295,000 to ~320,000 years ago by argon-40/argon-39 and uranium-series methods. Hominins at these sites made prepared cores and points, exploited iron-rich rocks to obtain red pigment, and procured stone tool materials from ≥25- to 50-kilometer distances. Associated fauna suggests a broad resource strategy that included large and small prey. These practices imply notable changes in how individuals and groups related to the landscape and to one another and provide documentation relevant to human social and cognitive evolution.

Observational Multicenter Study of a Direct-to-CT Protocol for EMS-transported Patients with Suspected Stroke.

OBJECTIVE: In an effort to decrease door-to-needle times for patients with acute ischemic stroke, some hospitals have begun taking stable EMS patients with suspected stroke directly from the ambulance to the CT scanner, then to an emergency department (ED) bed for evaluation. Minimal data exist regarding the potential for time savings with such a protocol. The study hypothesis was that a direct-to-CT protocol would be associated with decreases in both door-to-CT-ordered and door-to-needle times. METHODS: An observational, multicenter before/after study was conducted of time/process measures at hospitals that have implemented direct-to-CT protocols for patients transported by EMS with suspected stroke. Participating hospitals submitted data on at least the last 50 "EMS stroke alert" patients before the launch of the direct-to-CT protocol, and at least the first 50 patients after. Time elements studied were arrival at the ED, time the head CT was ordered, and time tPA was started. Data were submitted in blinded fashion (patient and hospital identifiers removed); at the time of data analysis, the lead investigator was unaware of which data came from which hospital. Simple descriptive statistics were used, along with the Mann-Whitney test to compare time medians. RESULTS: Seven hospitals contributed data on 1040 patients (529 "before" and 511 "after"); 512 were male, and 627 had final diagnoses of ischemic stroke, of whom 275 received tPA. The median door-to-CT-ordered time for all patients was 7 minutes in the before phase, and 4 minutes after (difference 3 minutes, p = < 0.0001); similarly, the median door-to-CT-started time was 6 minutes "before" and 10 minutes after (p < 0.0001). The median door-to-needle time for all patients given tPA was 42 minutes before, and 44 minutes after (p = 0.78). Four hospitals had modest decreases in door-to-CT-ordered time (of 2, 4, 2, and 5 minutes), and only one hospital had a decrease in door-to-needle time (32 min vs 26 min, p = 0.012). CONCLUSIONS: In this sample from seven hospitals, a minimal reduction in door-to-CT-ordered and door-to-CT-started time, but no change in door-to-needle time, was found for EMS patients with suspected stroke taken directly to the CT scanner, compared to those evaluated in the ED prior to CT.

Allergic Reaction to Ketamine as Monotherapy for Procedural Sedation.

BACKGROUND: Ketamine is a cyclohexamine derivative that acts as a noncompetitive N-methyl D-aspartate receptor antagonist. Its use for procedural sedation is recommended by national clinical policy. However, its immunogenic potential is not well documented. CASE REPORT: We report a case of allergic reaction associated with the administration of intravenous ketamine for procedural sedation in a 16-year-old male. Minutes after administration, the patient developed a morbilliform, erythematous rash that extended to the upper and lower torso and resolved with intravenous diphenhydramine. It is most likely that this allergic reaction was caused by a ketamine-induced histamine release that has been described in vitro. WHY SHOULD AN EMERGENCY PHYSICIAN BE AWARE OF THIS?: This is the first case report in which ketamine was used as monotherapy in the emergency department for the facilitation of procedural sedation that resulted in an allergic reaction. Supportive measures, including advanced airway procedures and hemodynamic support, may be necessary in more severe anaphylactic cases. Providers should be aware of this potential adverse effect when using ketamine for procedural sedation.

Cardiac arrest in special populations.

In certain cardiac arrest situations, modifications to current cardiac resuscitation algorithms may improve patient outcome. These situations are often rare, but when they occur they house the potential for severe time and resource use, and in some cases specialized skill sets. The decision to apply these modifications to standard care for the cardiac arrest patient may be obvious in some cases or may be applied due to suspicion from the presenting medical history, history of present illness, or physical examination. However, with rare exception, general care of any cardiac arrest patient should include continuous high-quality chest compressions and appropriate airway and ventillatory management.

Freedom, equality, race.

This essay explores come of the reasons for the continuing power of racial categorization in our era, and thus offers some friendly amendments to the more optimistic renderings of the term post-racial. Focusing mainly on the relationship between black and white Americans, it argues that the widespread embrace of universal values of freedom and equality, which most regard as antidotes to racial exclusion, actually reinforce it. The internal logic of these categories requires the construction of the "other." In America, where freedom and equality still stand at the contested center of collective identity, a history of racial oppression informs the very meaning of these terms. Thus the irony: much of the effort exerted to transcend race tends to fuel continuing division.

Part 1: executive summary: 2010 American Heart Association Guidelines for Cardiopulmonary Resuscitation and Emergency Cardiovascular Care.

The goal of therapy for bradycardia or tachycardia is to rapidly identify and treat patients who are hemodynamically unstable or symptomatic due to the arrhythmia. Drugs or, when appropriate, pacing may be used to control unstable or symptomatic bradycardia. Cardioversion or drugs or both may be used to control unstable or symptomatic tachycardia. ACLS providers should closely monitor stable patients pending expert consultation and should be prepared to aggressively treat those with evidence of decompensation.
