RESUMEN

PURPOSE: The intravenous (IV) medication compounding workflow has long been associated with preventable medication errors. This has led to the development of technologies designed to enhance the safety of IV compounding workflows. Digital image capture is a component of this technology about which there is relatively limited published literature. This study evaluates image capture implemented within an electronic health record's existing first-party IV workflow solution. METHODS: A retrospective case-control study was conducted to measure IV preparation times before and after digital imaging implementation. Preparations during 3 periods (preimplementation, ≤1 month post implementation, and >1 month post implementation) were matched for 5 variables. A less stringent analysis with matching for 2 variables, as well as an unmatched analysis, were performed post hoc. An employee survey assessed satisfaction with the digital imaging workflow, and revised orders were reviewed to identify new problems introduced by image capture. RESULTS: A total of 134,969 IV dispenses were available for analysis. Median preparation time in the preimplementation and >1 month post implementation cohorts was unchanged in the 5-variable matched analysis (6.87 minutes vs 6.58 minutes, P = 0.14) and increased in the 2-variable matched analysis (6.98 minutes vs 7.35 minutes, P < 0.001) and unmatched analysis (6.55 minutes vs 8.02 minutes, P < 0.001). A large majority of survey respondents (92%) felt that image capture improved patient safety. Of the 105 postimplementation preparations identified as requiring revisions by the checking pharmacist, 24 (22.9%) required revisions directly related to camera functionality. CONCLUSION: Implementation of digital image capture likely increased preparation times. Most IV room staff felt that image capture increased preparation times and were satisfied with how the technology improved patient safety. Image capture introduced camera-specific issues that led to preparations requiring revisions.

RESUMEN

OBJECTIVE: To determine the association between cervical nonorganic pain signs and epidural corticosteroid injection outcomes and coexisting pain and psychiatric conditions. PATIENTS AND METHODS: Seventy-eight patients with cervical radiculopathy who received epidural corticosteroid injection were observed to determine the effects that nonorganic signs have on treatment outcome. A positive outcome was a decrease of 2 or more points in average arm pain, coupled with a score of 5 on a 7-point Patient Global Impression of Change scale 4 weeks after treatment. Nine tests in 5 categories (abnormal tenderness, regional disturbances deviating from normal anatomy, overreaction, discrepancies in examination findings with distraction, and pain during sham stimulation) were modified from previous studies and standardized. Other variables examined for their association with nonorganic signs and outcomes included disease burden, psychopathology, coexisting pain conditions, and somatization. RESULTS: Of the 78 patients, 29% (n=23) had no nonorganic signs, 21% (n=16) had signs in 1 category, 10% (n=8) had signs in 2 categories, 21% (n=16) had signs in 3 categories, 10% (n=8) had signs in 4 categories, and 9% (n=7) had signs in 5 categories. The most common nonorganic sign was superficial tenderness (44%; n=34). Mean number of positive nonorganic categories was higher in individuals with negative treatment outcomes (2.5±1.8; 95% CI, 2.0 to 3.1) compared with those with positive outcomes (1.1±1.3; 95% CI, 0.7 to 1.5; P=.0002). Negative treatment outcomes were most strongly associated with regional disturbances and overreaction. Positive associations were noted between nonorganic signs and multiple pain (P=.011) and multiple psychiatric (P=.028) conditions. CONCLUSION: Cervical nonorganic signs correlate with treatment outcome, pain, and psychiatric comorbidities. Screening for these signs and psychiatric symptoms may improve treatment outcomes. TRIAL REGISTRATION: ClinicalTrials.gov identifier: NCT04320836.

RESUMEN

BACKGROUND: Medical affirmation, including gender-affirming hormones, is an essential component in the treatment of many transgender and gender-diverse youth. The risk of venous thromboembolism (VTE) during testosterone therapy for gender-affirming care is not fully elucidated. OBSERVATION: The case describes a 17-year-old transgender male treated with testosterone therapy who presented with an occlusive deep vein thrombosis of right axillary and subclavian veins. Testosterone level was 920 ng/dL at the time of the deep vein thrombosis, and he had no risk factors for VTE. A complete hypercoagulable workup was negative. CONCLUSIONS: The possibility of testosterone therapy as a risk factor for VTE may suggest the need to include this information during informed consent discussions. Long-term anticoagulation may be considered for those restarting testosterone therapy.

RESUMEN

Complex regional pain syndrome (CRPS) is a relatively rare, but debilitating condition that may occur after limb or peripheral nerve trauma. Typical symptoms of CRPS include swelling, allodynia, hyperalgesia, and skin temperature changes. Although a variety of pharmacological and non-pharmacological approaches are commonly used in caring for individuals with CRPS, they are frequently ineffective and often associated with side effects and/or additional risks. Previously, elastomeric orthotic garments have been shown to decrease neuropathic pain, reduce edema, and increase proprioception, but no previous reports have described their use in treating CRPS. Accordingly, this case series describes our experiences using a Lycra-based, custom-fabricated Dynamic Movement Orthosis (DMO) as a novel treatment to reduce the symptoms of CRPS and promote function. Four patients were included in this case series, all of whom had very different causes for their CRPS, including a combat-related gunshot injury resulting in multiple foot fractures with a partial nerve injury, a post-metatarsophalangeal fusion, an L5 radiculopathy, and a case of post-lower leg fasciotomies. These four patients all reported subjective improvement in their pain, function, and exercise tolerance in association with their DMO use. All patients demonstrated reduced use of analgesic medications. The pre- and post-DMO lower extremity functional scale showed clinically significant improvement in the two patients for which it was obtained.

RESUMEN

Bone marrow-derived mesenchymal stem and stromal cells (BM-MSCs) protect malignant cells from chemotherapy and are important potential therapeutic targets. Isolating primary BM-MSCs for research traditionally requires the sacrifice of valuable cell populations from within the same sample. To avoid this, we report here a resource for isolating patient-derived BM-MSCs from the red blood cell layer of ficoll gradients of bone marrow aspirates, a resource that has until now been universally discarded. This resource yields BM-MSCs nearly identical to those obtained conventionally and includes cells with a more stem-cell like nature. Obtaining primary BM-MSCs in this way will likely expand opportunities to study this important cell population.

RESUMEN

The purpose of this article is to provide information on the history, accomplishments, and future direction of the Bt brinjal (eggplant) program in Bangladesh, formerly under the Agricultural Biotechnology Support Project II, now the South Asia Eggplant Improvement Partnership (SAEIP). The India-based Maharashtra Hybrid Seed Company (Mahyco) developed an eggplant expressing Cry1Ac (EE-1) for control of the eggplant fruit and shoot borer (EFSB). In a partnership among Mahyco, USAID, Sathguru Management Consultants and Cornell University EE-1 was provided to the Bangladesh Agricultural Research Institute (BARI) who bred it into local varieties. After regulatory approval, four varieties were distributed to 20 farmers who harvested Bt brinjal in 2014. Adoption in subsequent years has increased rapidly so that, in 2018, 27,012 farmers used this technology. This article provides background information on the process leading up to current adoption levels, the level of control of EFSB achieved and the economic benefits of Bt brinjal. Efforts on stewardship, farmer training and communication are discussed. In order to ensure the long-term future of the partnership, we discuss the need to enhance involvement of the private sector in the production and stewardship of Bt eggplant. Bt brinjal is the first genetically engineered crop to be commercially released in Bangladesh, and other GE crops are in the pipeline. Hence, success of the Bt brinjal partnership is likely to affect the future of other GE crops in Bangladesh, as well as other parts of the world where biotechnology is needed for food security and environmental safety.

RESUMEN

DNA methylation of the Fragile X mental retardation 1 (FMR1) exon 1/intron 1 boundary has been associated with executive dysfunction in female carriers of a FMR1 premutation (PM: 55-199 CGG repeats), whereas neuroanatomical changes have been associated with executive dysfunction in PM males. To our knowledge, this study for the first time examined the inter-relationships between executive function, neuroanatomical structure and molecular measures (DNA methylation and FMR1 mRNA levels in blood) in PM and control (<44 CGG repeats) females. In the PM group, FMR1 intron 1 methylation was positively associated with executive function and cortical thickness in middle and superior frontal gyri, and left inferior parietal gyrus. By contrast, in the control group, FMR1 intron 1 methylation was negatively associated with cortical thickness of the left middle frontal gyrus and superior frontal gyri. No significant associations were revealed for either group between FMR1 mRNA and neuroanatomical structure or executive function. In the PM group, the lack of any significant association between FMR1 mRNA levels and phenotypic measures found in this study suggests that either FMR1 expression is not well conserved between tissues, or that FMR1 intron 1 methylation is linked to neuroanatomical and cognitive phenotype in PM females via a different mechanism.

RESUMEN

High-dose melphalan with stem cell transplantation (HDM/SCT) extends survival and induces hematologic and clinical responses in patients with light chain (AL) amyloidosis. Eighty percent of melphalan is bound to plasma proteins (60% albumin-bound). We hypothesized that patients with profound hypoalbuminemia have a greater free melphalan fraction and more toxicity. Patients with AL amyloidosis treated with HDM/SCT between 2011 and 2014 with severe hypoalbuminemia (SH), defined as serum albumin ⩽2 g/dL were studied retrospectively. Sixteen patients with SH were identified. Forty-one patients without severe hypoalbuminemia (WSH) treated between 2011 and 2012 served as control. The incidence of acute renal failure requiring hemodialysis was 25% among patients with SH, compared with 5% among patients WSH (P=0.05). Not all patients who needed dialysis required it long term; 6.25% for SH and 2.44% for WSH (P=0.49). The rates of grade 3 or 4 febrile neutropenia and gastrointestinal toxicities were not significantly different between the groups. Engraftment kinetics were similar for both groups. Grade 4 renal toxicity and grade 3 lightheadedness were more frequent in patients with SH undergoing HDM/SCT for AL amyloidosis. Further studies into the mechanism of increased renal toxicity in patients with SH are warranted.

RESUMEN

We describe a novel, interprofessional educational intervention pilot used to orient new health profession employees through the simulation laboratory. Health profession employees were recruited to engage in a simulation training session that focused on communication, collaboration, and healthcare roles and responsibilities. Learners (N = 11) were divided into two groups with representation from various health disciplines. Each group participated in a simulated patient scenario while the other group actively observed in another classroom. At the end of both sessions, the group reconvened for a debriefing session. Participants were given a survey before and after the training session, to evaluate the content, experience, and value to their practice. The pre- and post-evaluation survey analysis showed improvement in all objectives with a mean (SD) pre-evaluation score of 4.10 (0.40-1.01) and mean (SD) post-evaluation score of 4.73 (0.30-0.81). Results were favourable, and plans to expand this project are under way.

RESUMEN

OBJECTIVES: To develop a questionnaire to assess the psychosocial aspects which orthognathic patients considered important regarding their dento-facial deformity. SETTING AND SAMPLE POPULATION: A multicentre, prospective, questionnaire development and validation study based in the UK. MATERIAL AND METHODS: Questionnaire development involved item (question) selection through literature review, consultation and feedback from a questionnaire development group and semi-structured interviews. A 'final' questionnaire was tested on a cross-sectional sample of 110 pre-operative and 74 post-operative orthognathic patients and a longitudinal sample of 23 orthognathic patients. Validity was tested using Rasch analysis. RESULTS: Reliability for the Hospital Anxiety and Depression Scale (HADS) section was unsatisfactory (ICC = 0.232-0.829, Cronbach alpha = 0.625-0.670), but for the well- being (ICC = 0.857, Cronbach alpha = 0.827-0.895) and expectations (ICC = 0.861, Cronbach alpha = 0.804-0.882) sections were satisfactory. The well-being section was the only section found to be valid for the pre-and post-operative samples. Responsiveness was satisfactory for the well-being scale (p = 0.001). CONCLUSIONS: A new condition-specific orthognathic questionnaire has been developed which has been shown to be reliable, valid and responsive for the well-being scale. The HADS, as tested by Rasch analysis, was found not to be valid for this orthognathic population.

RESUMEN

Onion thrips, Thrips tabaci Lindeman (Thysanoptera: Thripidae), is an important pest on onion and cabbage. Two reproductive modes--arrhenotoky and thelytoky--are found in this species and co-occur in the field. We compared life table traits between arrhenotokous and thelytokous T. tabaci on cabbage and onion. Experiments were conducted in cages to determine which reproductive mode is more competitive. Additionally, host adaption of the arrhenotokous and thelytokous T. tabaci between onion and cabbage was investigated. On onion, arrhenotokous T. tabaci performed better than thelytokous T. tabaci, while on cabbage the opposite occurred. When comparing life table and demographic growth parameters (net reproductive rates R(o), mean generation time T, the intrinsic rate of natural increase r(m), finite rate of increase A, and population doubling time T(d)) on different host plants, we found that arrhenotokous T. tabaci performed better on onion than on cabbage, whereas thelytokous T. tabaci performed better on cabbage than on onion. Host-related performance differences in this species suggest that the divergence between two reproductive modes might be associated with host adaption. Pest management strategies for this global pest should recognize that the two reproductive modes can impact population dynamics on different crops.

RESUMEN

Field tests in 2010-2011 were performed in New York, Minnesota, Maryland, Ohio, and Georgia to compare Bt sweet corn lines expressing Cry1A.105 + Cry2Ab2 and Cry1Ab with their non-Bt isolines, with and without the use of foliar insecticides. The primary insect pest in all locations during the trial years was Heliocoverpa zea (Boddie), which is becoming the most serious insect pest of sweet corn in the United States. At harvest, the ears were measured for marketability according to fresh market and processing standards. For fresh market and processing, least squares regression showed significant effects of protein expression, state, and insecticide frequency. There was a significant effect of year for fresh market but not for processing. The model also showed significant effects of H. zea per ear by protein expression. Sweet corn containing two genes (Cry1A.105 + Cry2Ab2) and a single gene (Cry1Ab) provided high marketability, and both Bt varieties significantly outperformed the traditional non-Bt isolines in nearly all cases regardless of insecticide application frequency. For pest suppression of H. zea, plants expressing Bt proteins consistently performed better than non-Bt isoline plants, even those sprayed at conventional insecticide frequencies. Where comparisons in the same state were made between Cry1A.105 + Cry2Ab2 and Cry1Ab plants for fresh market, the product expressing Cry1A.105 + Cry2Ab2 provided better protection and resulted in less variability in control. Overall, these results indicate Cry1A.105 + Cry2Ab2 and Cry1Ab plants are suitable for fresh market and processing corn production across a diversity of growing regions and years. Our results demonstrate that Bt sweet corn has the potential to significantly reduce the use of conventional insecticides against lepidopteran pests and, in turn, reduce occupational and environmental risks that arise from intensive insecticide use.

RESUMEN

Co-management and critical care outreach for high risk surgical patients have been proposed to decrease postoperative complications and mortality. We proposed that a clinical project with postoperative comanagement and critical care outreach, the Post Operative Surveillance Team: (POST), would be associated with decreased hospital length of stay. We conducted a retrospective before (control group) and after (POST group) audit of this hospital program. POST was staffed for four months in 2010 by two intensive care nurses and two senior registrars who conducted daily ward rounds for the first five postoperative days on high risk patients undergoing inpatient general or urological surgery. The primary endpoint was length of hospital stay and secondary endpoints were Medical Emergency Team (MET) calls, cardiac arrests and in-hospital mortality. There were 194 patients in the POST group and 1,185 in the control group. The length of stay in the POST group, median nine days (Inter-quartile range [IQR]: 5 to 17 days), was longer than the control group, median seven days (IQR: 4 to 13 days): difference two days longer (95.0% confidence interval [95.0% CI]: 1 to 3 days longer, P <0.001). There were no important differences in the proportion of patients having MET calls (16.0% POST versus. 13% control (P=0.25)) or mortality (2.1% POST versus 2.8% Control (P=0.82)). Our audit found that the POST service was not associated with reduced length of stay. Models of co-management, different to POST, or with different performance metrics, could be tested.

RESUMEN

INTRODUCTION: The purpose of this study was to evaluate the use of a patient-directed static progressive stretch orthosis for the treatment of shoulder stiffness. METHODS: Twenty-three patients who had limitations in range of motion of the shoulder and who had failed conventional physical therapy methods were studied. This cohort included 15 women and 8 men with a mean age of 53 years. Treatment comprised one to three 30- to 60-minute sessions per day with a patient-controlled orthosis utilizing static progressive stretch. The patients adjusted the degree of stretch at 5-minute intervals as tolerated. Compliance, range of motion, patient satisfaction, and complications were assessed, and a two-way repeated measure ANOVA was performed to assess the effects of age or gender. RESULTS: After a mean treatment duration of 10 weeks (range, 4 to 19 weeks), the patients gained a mean of 22° (range, -47 to 57°) of external rotation, 18° (range, -19 to 55°) of internal rotation, 46° (range, 3 to 97°) of abduction, and 23° (range, 3 to 40°) of forward flexion. In total, 22 of 23 patients (96%) experienced increases in range of motion that were maintained at 1 year following treatment. Statistically significant increases in range of motion and clinical function scores were noted; age and gender did not appear to influence the outcomes. DISCUSSION: This device compared favorably to other treatment methods for shoulder stiffness. An orthosis utilizing static progressive stretch was a useful adjunct for the treatment of shoulder stiffness refractory to conventional therapy.

RESUMEN

Dietary CLA has been reported to decrease backfat and increase marbling in pigs. Our objective was to determine whether the increase in marbling involved changes in intramuscular adipocyte number or size or both. Twenty barrows (53 kg) were penned in pairs and pens were randomly assigned to receive diets containing either 1% soybean oil (SBO) or CLA (60% CLA isomers) for 6 wk. Body weight and feed intake were determined weekly. At slaughter, loin samples were obtained and flash frozen for RNA extraction and real-time reverse-transcription PCR analysis of gene expression. After a 24-h chill, loin eye area and backfat depth were measured and subjective marbling and color scores were assigned. Loin, backfat, and belly fat samples were obtained for fatty acid analysis by gas chromatography. Loin samples were also frozen in ice-cold isopentane for histological analysis of intramuscular adipocytes. Dietary CLA did not affect BW or feed intake at any point (P > 0.10), nor did treatment groups differ in HCW (P = 0.417) or loin color (P = 0.500). The CLA-fed pigs did have less (P = 0.018) backfat and smaller (P = 0.047) loin eye area than SBO-fed pigs and had a trend for an increase (P = 0.069) in marbling score. Relative gene expression for markers of preadipocytes (preadipocyte factor 1; Pref-1), differentiating adipocytes (PPARγ), and mature adipocytes [fatty acid binding protein 4 (FABP4) and perilipin (PLIN)] were determined and normalized to the expression of acidic ribosomal phosphoprotein. No significant differences were detected, but the expression of PPARγ (P = 0.265), PLIN (P = 0.265), and FABP4 (P = 0.148) was numerically greater in CLA-fed pigs than in SBO-fed pigs. Loin samples were stained with Oil Red O to identify intramuscular adipocytes. The average cell area was increased (P = 0.030) in CLA-fed pigs. The cis-9,trans-11 and trans-10,cis-12 CLA isomers were incorporated (P = 0.006) into backfat and belly fat, but only trans-10,cis-12 CLA was increased in the loin (P = 0.004) of CLA-fed pigs. The proportion of SFA was increased (P = 0.006) by CLA in all tissues. These results indicate that the increase in marbling in pigs fed CLA may be related to increased intramuscular adipocyte size, and the combination of increased marbling and degree of saturation could improve the eating quality of CLA-fed pork.

RESUMEN

BACKGROUND CONTEXT: Nonbattle illnesses and injuries are the major causes of unit attrition in modern warfare. Spine-area pain is a common disabling injury in service members associated with a very low return-to-duty (RTD) rate. PURPOSE: To provide an overview of the current understanding of epidemiology, possible causes, and relative prognosis of spine-area pain syndromes in military personnel, including a discussion of various treatment options available in theaters of operation. STUDY DESIGN: Literature review. METHODS: Search focusing on epidemiology, etiology and associative factors, and treatment of spinal pain using electronic databases, textbooks, bibliographic references, and personal accounts. RESULTS: Spine-area pain is the most common injury or complaint "in garrison" and appears to increase during training and combat deployments. Approximately three-quarters involve low back pain, followed by cervical and midback pain syndromes. Some predictive factors associated with spine-area pain are similar to those observed in civilian cohorts, such as psychosocial distress, heavy physical activity, and more sedentary lifestyle. Risk factors specific to military personnel include concomitant psychological trauma, g-force exposure in pilots and airmen, extreme shock and vibration exposure, heavy combat load requirements, and falls incurred during airborne, air assault, and urban dismounted ground operations. Effective forward-deployed treatment has been difficult to implement, but newer strategies may improve RTD rates. CONCLUSIONS: Spine-area pain syndromes comprise a major source of unit attrition and are often the result of duty-related burdens incurred during combat operations. Current strategies in theaters of operation that may improve the low RTD rates include individual and unit level psychological support, early resumption of at least some forward-area duties, multimodal treatments, and ergonomic modifications.
