RESUMEN
BACKGROUND: An accurate weight is critical for dosing medications in children. Weight errors can lead to medication-dosing errors. OBJECTIVES: This study examined the frequency and consequences of weight errors occurring at 1 children's hospital and 2 general hospitals. METHODS: Using an electronic medical record database, 79,000 emergency department encounters of children younger than 5 years were analyzed. Extreme weights were first identified using weight percentiles. Encounters with potential weight errors were further evaluated using a retrospective chart review to determine whether a weight error and medication-dosing error occurred. RESULTS: The percentage of weight errors of total encounters at all 3 institutions was low (0.63% on average), but a large proportion of weight errors led to subsequent medication-dosing errors (34% on average). The children's hospital did not have clinically significantly lower occurrences of weight errors or weight-based medication errors. Common weight errors included the weight in pounds being substituted for the weight in kilograms and decimal placement errors. CONCLUSIONS: Weight errors were uncommon at the 3 emergency departments that we studied, but they led to weight-based medication-dosing errors that had the potential to cause harm.

Introduction: Burnout syndrome (BS) is a prevalent occupational health problem in health professionals. To describe the prevalence and factors associated with BS in Peruvian health professionals. Method: A systematic review and meta-analysis were performed. The key terms "burnout" and "professional exhaustion" were used with words related to Peru. The databases consulted were LILACS/Virtual Health Library, Medline/PubMed, Science Direct, EBSCO, Scopus, SciELO, and RENATI-SUNEDU; articles published between January 2000 to December 2020 were considered for inclusion. Methodological quality was evaluated using the Newcastle-Ottawa scale. Results: Thirty studies were identified (8 scientific articles and 22 graduate theses). The median sample size was 78, with an interquartile range of 50-110. A meta-analysis was performed to calculate a dichotomic prevalence of burnout syndrome in health professionals of 25 % (95%CI: 9 %-45 %; I2 = 97.14 %; 5 studies). Also, our meta-analysis estimated the overall prevalence of mild burnout (27 %; 95%CI: 16%-41 %; I2 = 96.50 %), moderate burnout (48 %; 95%CI: 32%-65 %; I2 = 97.54 %), and severe burnout (17 %; 95%CI: 10%-24 %; I2 = 92.13 %; 18 studies). We present meta-analyses by region, profession, hospital area, and by dimension of the Maslach Burnout Inventory. Overall, the studies presented adequate levels of quality in 96.7 % of the included studies (n = 29). In addition, our narrative review of factors associated with BS and its three dimensions identified that different studies find associations with labor, socio-demographic, individual, and out-of-work factors. Conclusions: There is a higher prevalence of moderate BS in Peruvian health professionals at MINSA and EsSalud hospitals in Peru, with severity differing by region of Peru, type of profession, work area, and dimensions of BS.
RESUMEN
Although receiving adjuvant chemotherapy after radical surgery, a disappointing proportion of patients with colorectal cancer will develop tumor recurrence. Probability of relapse is currently predicted from pathological staging, there being a need for additional markers to further select high-risk patients. This study was aimed to identify a gene-expression signature to predict tumor recurrence in patients with Stages II and III colon cancer treated with 5'fluoruracil (5FU)-based adjuvant chemotherapy. Two-hundred and twenty-eight patients diagnosed with Stages II-III colon cancer and treated with surgical resection and 5FU-based adjuvant chemotherapy were included. RNA was extracted from formalin-fixed, paraffin-embedded tissue samples and expression of 27 selected candidate genes was analyzed by RT-qPCR. A tumor recurrence predicting model, including clinico-pathological variables and gene-expression profiling, was developed by Cox regression analysis and validated by bootstrapping. The regression analysis identified tumor stage and S100A2 and S100A10 gene expression as independently associated with tumor recurrence. The risk score derived from this model was able to discriminate two groups with a highly significant different probability of tumor recurrence (HR, 2.75; 95%CI, 1.71-4.39; p = 0.0001), which it was maintained when patients were stratified according to tumor stage. The algorithm was also able to distinguish two groups with different overall survival (HR, 2.68; 95%CI, 1.12-6.42; p = 0.03). Identification of a new gene-expression signature associated with a high probability of tumor recurrence in patients with Stages II and III colon cancer receiving adjuvant 5FU-based chemotherapy, and its combination in a robust, easy-to-use and reliable algorithm may contribute to tailor treatment and surveillance strategies.

The endocannabinoid system is a key regulator of the response to psychological stress. Inhibitors of monoacylglycerol lipase (MGL), the enzyme that deactivates the endocannabinoid 2-arachidonoyl-sn-glycerol (2-AG), exert anxiolytic-like effects in rodent models via 2-AG-dependent activation of CB1 cannabinoid receptors. In the present study, we examined whether the MGL inhibitor JZL184 might modulate persistent predator-induced fear in rats, a model that captures features of human post-traumatic stress disorder. Exposure to 2,5-dihydro-2,4,5-trimethylthiazoline (TMT), a volatile chemical that is innately aversive to some rodent species, produced in male rats a long-lasting anxiety-like state that was measured 7 days later in the elevated plus maze test. Systemic administration of JZL184 [4, 8 and 16 mg/kg, intraperitoneal (IP)] 4 h before testing caused dose-dependent inhibition of MGL activity and elevation of 2-AG content in brain tissue. Concomitantly, the inhibitor suppressed TMT-induced fear behaviors with a median effective dose (ED50) of 4 mg/kg. A similar behavioral response was observed with another MGL inhibitor, KML29 (4 and 16 mg/kg, IP). Surprisingly, the effect of JZL184 was prevented by co-administration of the CB2 inverse agonist AM630 (5 mg/kg, IP), but not the CB1 inverse agonist rimonabant (1 mg/kg, IP). Supporting mediation of the response by CB2 receptors, the CB2 agonist JWH133 (0.3, 1 and 3 mg/kg, IP) also produced anxiolytic-like effects in TMT-stressed rats, which were suppressed by AM630. Notably, (i) JWH133 was behaviorally ineffective in animals that had no prior experience with TMT; and (ii) CB2 mRNA levels in rat prefrontal cortex were elevated 7 days after exposure to the aversive odorant. The results suggest that JZL184 attenuates the behavioral consequences of predator stress through a mechanism that requires 2-AG-mediated activation of CB2 receptors, whose transcription may be induced by the stress itself.

RATIONALE: The endocannabinoid neurotransmitter, anandamide, has been implicated in the central modulation of stress responses. Previous animal experiments have shown that inhibitors of the anandamide-degrading enzyme, fatty acid amide hydrolase (FAAH), enhance the ability to cope with acute and chronic stress. OBJECTIVES: Here, we investigated the effects of the globally active FAAH inhibitor URB597 in a rat model of predator stress-induced long-term anxiety. RESULTS: Rats exposed to 2,5-dihydro-2,4,5-trimethylthiazoline (TMT), a chemical constituent of fox feces, developed a persistent anxiety-like state, which was assessed 7 days after exposure using the elevated plus maze (EPM) test. Systemic administration of URB597 [0.03-0.1-0.3 mg/kg, intraperitoneal (ip)] 2 h before testing suppressed TMT-induced behaviors with a median effective dose (IC50) of 0.075 mg/kg. This effect was strongly correlated with inhibition of brain FAAH activity (r2 = 1.0) and was accompanied by increased brain levels of three FAAH substrates: the endocannabinoid anandamide and the endogenous peroxisome proliferator-activated receptor-α (PPAR-α) agonists, oleoylethanolamide (OEA), and palmitoylethanolamide (PEA). The anxiolytic-like effects of URB597 were blocked by co-administration of the CB1 receptor antagonist rimonabant (1 mg/kg, ip), but not of the PPAR-α antagonist GW6471 (1 mg/kg, ip). Finally, when administered 18 h after TMT exposure (i.e., 6 days before the EPM test), URB597 (0.3 mg/kg, ip) prevented the consolidation of anxiety-like behavior in a CB1-dependent manner. CONCLUSIONS: The results support the hypothesis that anandamide-mediated signaling at CB1 receptors serves an important regulatory function in the stress response, and confirm that FAAH inhibition may offer a potential therapeutic strategy for post-traumatic stress disorder.

OBJECTIVES: The differences between pediatric (< or = 17 years of age) and adult clinical field encounters were analyzed from four deployments of Disaster Medical Assistance Teams (DMATs). METHODS: A retrospective cohort review of all patients who presented to DMAT field clinics during two hurricanes, one earthquake, and one flood was conducted. Descriptive statistics were used to analyze: (1) age; (2) gender; (3) severity category level; (4) chief complaint; (5) treatments provided; (6) discharge diagnosis; and (7) disposition. Five subsets of pediatric patients were analyzed further. RESULTS: Of the 2,196 patient encounters reviewed, 643 (29.5%) encounters were pediatric patients. Pediatric patients had a greater number of blank severity category levels than adults. Pediatric patients also were: (1) more likely to present with chief complaints of upper respiratory infections or wounds; (2) less likely to present with musculoskeletal pain or abdominal pain; and (3) equally likely to present with rashes. Pediatric patients were more likely to receive antibiotics, pain medication, and antihistamines, but were equally likely to need treatment for wounds. Dispositions to the hospital were less frequent for pediatric patients than for adults. CONCLUSIONS: Pediatric patients represent a substantial proportion of disaster victims at DMAT field clinics. They often necessitate special care requirements different from their adult counterparts. Pediatric-specific severity category criteria, treatment guidelines, equipment/medication stocks, and provider training are warranted for future DMAT response preparations.

To aid disaster planning, a retrospective review of patients seen by New Mexico 1 Disaster Medical Assistance Team (NM-1 DMAT) after four disasters was conducted. Data analyzed included age, gender, past medical history, chief complaint, diagnosis, diagnostic testing, treatment, triage category, disposition, and time to presentation after the disaster. Data were analyzed for differences between patients presenting early vs. late after a disaster and to test if availability of diagnostic testing changed patient disposition. The results showed that the majority of patients presented with upper respiratory tract infection symptoms, wounds, and musculoskeletal pain. The needs of patients were similar whether they presented early or late. The same proportion of patients was transferred to hospitals when diagnostic testing was available vs. not available, despite a higher level of acuity when diagnostic testing was available. In conclusion, DMATs should be prepared to see high volumes of low acuity patients. Patient needs do not change with time. Diagnostic testing may be useful.

OBJECTIVES: The New Mexico-1 Disaster Medical Assistance Team (NM-1 DMAT) has responded to more disasters due to hurricanes than disasters from any other type of event. To assess whether defined patient needs may be applied to future hurricanes, the patient needs after Hurricanes Andrew and Iniki were compared. The study question was, "Did patient medical needs differ after these hurricanes?" DESIGN: Retrospective cohort review. SUBJECTS: All patients evaluated by NM-1 DMAT following Hurricanes Andrew and Iniki. OBSERVATIONS: Age, past medical history, chief complaint, diagnosis, diagnostic tests, treatments, triage level, and disposition. Age was analyzed using Student's t-test, other data were analyzed using the chi-square test. RESULTS: A total of 1,056 patients were evaluated. Age distributions did not differ between events. More patients had co-morbidities after Hurricane Andrew. The only difference in chief complaint was that more patients complained of "cold" symptoms following Hurricane Iniki. The only differences in diagnoses were for upper respiratory infections, which were diagnosed more often after Hurricane Iniki. There were no differences in the administration of tetanus toxoid, antibiotics, or analgesics. Patients evaluated after Hurricane Andrew had more diagnostic tests performed and a higher illness/injury acuity. The proportion of the total number of patients conveyed to a hospital did not differ. CONCLUSION: Patient needs were similar after Hurricane Andrew and Hurricane Iniki and may be applicable for predicting the needs of patients for future hurricanes.

PURPOSE: Transfusion of blood components is common in patients admitted to the intensive care unit (ICU) for gastrointestinal (GI) bleeding, yet the incidence and risk factors for development of transfusion-related acute lung injury (TRALI) in these patients are unknown. METHODS: Patients admitted to a medical ICU for GI bleeding (n = 225) were analyzed for patient- and transfusion-specific risk factors for development of TRALI. RESULTS: In transfused patients (n = 150), the incidence of TRALI was 15% [95% confidence interval (CI), 10-21%] and accounted for 76% (22/29) of all acute lung injury (ALI) cases. Transfused patients with end-stage liver disease (ESLD) (n = 72) developed TRALI more frequently than those without ESLD (29% versus 1%, p < 0.01). Fresh frozen plasma (FFP) was temporally associated with TRALI in 86% of cases. Transfusion-specific risk factors for development of TRALI included number of transfused units of FFP and nonleukoreduced red blood cells. Patient-specific risk factors included Model for End-Stage Liver Disease (MELD) score, admission serum albumin level, and presence of ALI risk factors. CONCLUSIONS: TRALI is common in critically ill ESLD patients with gastrointestinal bleeding. Nonleukoreduced red blood cells and FFP are significant transfusion-specific risk factors and their use should be re-evaluated in bleeding patients with ESLD.

OBJECTIVE: Through the review of patient records seen by the New Mexico-1 Disaster Medical Assistance Team (NM-1DMAT) after various disasters, we hoped to find patterns that might help in disaster planning. Our hypothesis was that flood and hurricane victims have different medical conditions and needs. METHODS: We conducted a retrospective review of patient records for NM-1DMAT deployments to Hurricane Andrew in Florida (August 1992) and the Houston, TX flood caused by Tropical Storm Allison (June 2001). We compared age, gender, chief complaint, medical history, diagnosis, diagnostic testing, treatment rendered, triage category, and patient disposition. RESULTS: We found several differences between the patients presenting after Hurricane Andrew and those presenting after Tropical Storm Allison. The chief complaint, diagnosis, presence of medical history, diagnostic testing, treatment rendered, triage category, and disposition all differed between the 2 disasters. The mean ages in both groups were similar. CONCLUSIONS: The needs of the patients differed in several areas between Hurricane Andrew and the Houston flood. This information should be tested in a future hurricane or flood and taken into account when planning for deployments.

Se presenta a un paciente de 63 años que en junio de 1991se le realizó desarticulación de ambas muñecas, amputación sobre rodilla derecha y bajo rodilla izquierda debido a una complicación de su patología de base: crioaglutininemia primaria Ig M a Frigori. Por su nivel socioeconómico de extrema pobreza y antecedentes de alcoholismo desde su infancia sumado a su patología se decidió independizarlo en silla de ruedas con adaptaciones y derivarlo a un centro geriátrico, objetivos que se cumplieron en siete semanas de hospitalización
