RESUMO
BACKGROUND: High-quality evidence for post-cardiotomy extracorporeal life support (PC-ECLS) management is lacking. This study investigated the real-world PC-ECLS clinical practices. METHODS: This cross-sectional, multi-institutional, international pilot survey explored center organization, anticoagulation management, left ventricular unloading, distal limb perfusion, PC-ECLS monitoring and transfusions practices. Twenty-nine questions were distributed among 34 hospitals participating in the Post-cardiotomy Extra-Corporeal Life Support Study. RESULTS: Of the 32 centers [16 low-volume (50%); 16 high-volume (50%)] that responded, 16 (50%) had dedicated ECLS specialists. Twenty-six centers (81.3%) reported using additional mechanical circulatory supports. Anticoagulation practices were highly heterogeneous: 24 hospitals (75%) reported using patient's bleeding status as a guide, without a specific threshold in 54.2% of cases. Transfusion targets ranged 7-10 g/dL. Most centers used cardiac venting on a case-by-case basis (78.1%) and regular distal limb perfusion (84.4%). Nineteen (54.9%) centers reported dedicated monitoring protocols including daily echocardiography (87.5%), Swan-Ganz catheterization (40.6%), cerebral near-infrared spectroscopy (53.1%) and multimodal assessment of limb ischemia. Inspection of the circuit (71.9%), oxygenator pressure drop (68.8%), plasma free hemoglobin (75%), d-dimer (59.4%), lactate dehydrogenase (56.3%) and fibrinogen (46.9%) are used to diagnose hemolysis and thrombosis. CONCLUSIONS: This study shows remarkable heterogeneity in clinical practices for PC-ECLS management. More standardized protocols and better implementation of available evidence are recommended.
RESUMO
Rationale: The role of and needs for extracorporeal membrane oxygenation (ECMO) at a population level during the coronavirus disease (COVID-19) pandemic have not been completely established. Objectives: To identify the cumulative incidence of ECMO use in the first pandemic wave and to describe the Nationwide Chilean cohort of ECMO-supported patients with COVID-19. Methods: We conducted a population-based study from March 3 to August 31, 2020, using linked data from national agencies. The cumulative incidence of ECMO use and mortality risk of ECMO-supported patients were calculated and age standardized. In addition, a retrospective cohort analysis was performed. Outcomes were 90-day mortality after ECMO initiation, ECMO-associated complications, and hospital length of stay. Cox regression models were used to explore risk factors for mortality in a time-to-event analysis. Measurements and Main Results: Ninety-four patients with COVID-19 were supported with ECMO (0.42 per population of 100,000, 14.89 per 100,000 positive cases, and 1.2% of intubated patients with COVID-19); 85 were included in the cohort analysis, and the median age was 48 (interquartile range [IQR], 41-55) years, 83.5% were men, and 42.4% had obesity. The median number of pre-ECMO intubation days was 4 (IQR, 2-7), the median PaO2/FiO2 ratio was 86.8 (IQR, 64-99) mm Hg, 91.8% of patients were prone positioned, and 14 patients had refractory respiratory acidosis. Main complications were infections (70.6%), bleeding (38.8%), and thromboembolism (22.4%); 52 patients were discharged home, and 33 died. The hospital length of stay was a median of 50 (IQR, 24-69) days. Lower respiratory system compliance and higher driving pressure before ECMO initiation were associated with increased mortality. A duration of pre-ECMO intubation ≥10 days was not associated with mortality. Conclusions: Documenting nationwide ECMO needs may help in planning ECMO provision for future COVID-19 pandemic waves. The 90-day mortality of the Chilean cohort of ECMO-supported patients with COVID-19 (38.8%) is comparable to that of previous reports.

Undergraduates in Spanish universities conclude their science degrees with a capstone project (CP) where they must apply the knowledge gained during their studies. In recent years, students in technical degrees often postponed this last step due to a fast entry into the labour market or disappointment about the development of their capstone projects. This article presents an approach that tries to overcome these challenges and avoid delays in project submission called Engagement capstone projects. The authors, supported by the French Company EOMYS, manage this educational project in which students become responsible for their contribution to a free and open software project called MOSQITO, which provides sound quality metrics based on psychoacoustics. A framework is provided to ensure involvement in the project by both students and academic/industrial supervisors to help avoid student discouragement. The proposed methodology is compared with the current program and the learning proposal, and the expected outcomes are extensively explained. The experience gathered to date is limited, but the results obtained show the potential application of the proposed Engagement capstone projects as a solution to late CP submission.

BACKGROUND: Because postlicensure surveillance determined that a previous rotavirus vaccine, RotaShield, caused intussusception in 1 of every 10,000 recipients, we assessed the association of the new monovalent rotavirus vaccine (RV1) with intussusception after routine immunization of infants in Mexico and Brazil. METHODS: We used case-series and case-control methods to assess the association between RV1 and intussusception. Infants with intussusception were identified through active surveillance at 69 hospitals (16 in Mexico and 53 in Brazil), and age-matched infants from the same neighborhood were enrolled as controls. Vaccination dates were verified by a review of vaccination cards or clinic records. RESULTS: We enrolled 615 case patients (285 in Mexico and 330 in Brazil) and 2050 controls. An increased risk of intussusception 1 to 7 days after the first dose of RV1 was identified among infants in Mexico with the use of both the case-series method (incidence ratio, 5.3; 95% confidence interval [CI], 3.0 to 9.3) and the case-control method (odds ratio, 5.8; 95% CI, 2.6 to 13.0). No significant risk was found after the first dose among infants in Brazil, but an increased risk, albeit smaller than that seen after the first dose in Mexico--an increase by a factor of 1.9 to 2.6 - was seen 1 to 7 days after the second dose. A combined annual excess of 96 cases of intussusception in Mexico (approximately 1 per 51,000 infants) and in Brazil (approximately 1 per 68,000 infants) and of 5 deaths due to intussusception was attributable to RV1. However, RV1 prevented approximately 80,000 hospitalizations and 1300 deaths from diarrhea each year in these two countries. CONCLUSIONS: RV1 was associated with a short-term risk of intussusception in approximately 1 of every 51,000 to 68,000 vaccinated infants. The absolute number of deaths and hospitalizations averted because of vaccination far exceeded the number of intussusception cases that may have been associated with vaccination.

BACKGROUND: Most patients who sustain a traumatic injury require outpatient follow-up. A common barrier to outpatient postadmission care is patient failure to follow-up. One of the most significant factors resulting in failure to follow-up is age more than 35 years. Recent work has shown that follow-up telephone calls reduce readmission rates. Our aim was to decrease no-show appointments by 10% in 12 months. STUDY DESIGN: The electronic medical records at our level I and II trauma centers were queried for all outpatient appointments for trauma between July 1, 2020, and June 9, 2021, and whether the patient attended their follow-up appointment. Patients with visits scheduled after August 1, 2021, received 24- and 48-hour previsit reminder calls. Patients with visits scheduled between July 1, 2020, and August 1, 2021, did not receive previsit calls. Both groups were compared using multivariable direct logistic regression models. RESULTS: A total of 1,822 follow-up opportunities were included in the study. During the pre-implementation phase, there was a no-show rate of 30.9% (329 of 1,064 visits). Postintervention, a 12.2% reduction in overall no-show rate occurred. A statistically significant 11.2% decrease (p < 0.001) was seen in elderly patients. Multivariate analysis showed standardized calls resulted in significantly decreased odds of failing to keep an appointment (adjusted odds ratio = 0.610, p < 0.001). CONCLUSIONS: Reminder calls led to a 12.2% reduction in no-show rate and were an independent predictor of a patient's likelihood of attending their appointment. Other predictors of attendance included insurance status and abdominal injury.

Hemodialysis treatment in specialized clinics within the same hospital significantly impacts environmental water health due to contaminated wastewater. The issues observed included changes in electrical conductivity, the presence of dangerous bacterial loads, toxicity from heavy metals, total cyanide content, and helminth parasite eggs. The level of damage is dependent on the patient's health under treatment. This research will use a modular system that employs electrocoagulation and electro-oxidation processes at the laboratory and pilot levels to treat hemodialysis wastewater using synthetically prepared and real samples extracted from local clinics. The results showed that these hybrid systems improved various physicochemical parameters. Specifically, decreases in electrical conductivity of 49 %, total suspended solids of 27-100 %, chemical oxygen demand of 49 %, biochemical oxygen demand of 49 %, and cation and anion loading were observed at 96-100 % and pHâ 8.13 UpH in accordance with the established standards. With these results and the experimental conditions used, the proposed treatment system was modeled using the GPS-X program, and it was concluded that the modular system used and the electrocoagulation/electro-oxidation/activated carbon configuration is suitable for treating wastewater from hemodialysis and that scaling up this process to facilities that have dialysate machines more advanced than those considered in this work is possible.

Background: Focused Assessment with Sonography in Trauma (FAST) examination is a point-of-care ultrasound study used to evaluate for abdominal hemorrhage, pneumothorax, or pericardial blood in trauma patients as an adjunct to their initial assessment. The quality of the image can be limited, and its diagnostic value is heavily dependent on operator skill. Our objective was to determine whether a standardized review process improved image quality and reduced incidence of nondiagnostic or insufficient imaging by 10% over a 6-month period. Study Design: Between July 1, 2021, and March 31, 2022, we evaluated 1106 trauma activations at our level II trauma center. Two exams per practitioner per month were reviewed by an emergency medicine trained traumatologist with specialized training in point-of-care ultrasound and board certification in echocardiography. Priority was given to exams on patients with known injuries identified on other studies. If there were no exams that matched these criteria, random exams were selected. Images were reviewed for image quality, diagnostic accuracy, and labeling with counseling given to the provider if indicated. Categorical variables were compared using chi squared analysis, while continuous non-normally distributed variables were compared using the Mann-Whitney U test. Results: A total of 305 FAST exams were reviewed (186 pre-intervention and 119 during intervention). Image quality improved from 46.3% (n = 31/65) to 79.0% (n = 94/119) (P < .01) with need for counseling falling from 63.1% (n = 41/65) pre-QI to 42.0% (n = 50/119) post-QI (P < .01). Incidence of detectable injury, BMI, ISS, and AIS body regions were consistent across the study period. This was seen in both the geriatric and non-geriatric cohorts despite a significant increase in ISS in the post-intervention geriatric patients.Discussion: A FAST review program is associated with improvement in image quality and decreased need for counseling of trauma providers.
RESUMO
BACKGROUND: Evaluation, development, and implementation of trauma systems in Latin America are challenging undertakings as no model is currently in place that can be easily replicated throughout the region. The use of teleconferencing has been essential in overcoming other challenges in the medical field and improving medical care. This article describes the use of international videoconferencing in the field of trauma and critical care as a tool to evaluate differences in care based on local resources, as well as facilitating quality improvement and system development in Latin America. MATERIALS AND METHODS: In February 2009, the International Trauma and Critical Care Improvement Project was created and held monthly teleconferences between U.S. trauma surgeons and Latin American general surgeons, emergency physicians, and intensivists. In-depth discussions and prospective evaluations of each case presented were conducted by all participants based on resources available. Care rendered was divided in four stages: (1) pre-hospital setting, (2) emergency room or trauma room, (3) operating room, and (4) subsequent postoperative care. Furthermore, the participating institutions completed an electronic survey of trauma resources based on World Health Organization/International Association for Trauma and Surgical Intensive Care guidelines. RESULTS: During a 17-month period, 15 cases in total were presented from a Level I and a Level II U.S. hospital (n=3) and five Latin American hospitals (n=12). Presentations followed the Advanced Trauma Life Support sequence in all U.S. cases but in only 3 of the 12 Latin American cases. The following deficiencies were observed in cases presented from Latin America: pre-hospital communication was nonexistent in all cases; pre-hospital services were absent in 60% of cases presented; lack of trauma team structure was evident in the emergency departments; during the initial evaluation and resuscitation, the Advanced Trauma Life Support protocol was followed one time and the Clinical Randomization of an Antifibrinolytic in Significant Hemorrhage protocol on two occasions; it was determined that imaging resources were adequately used in half of the cases; the initial care was mostly provided by emergency room physicians; and a surgeon, operating room, and intensive care unit were not readily available 83% of the time. The ease of patient flow was cumbersome because of a lack of a structured system for trauma care except for one academic urban center. Adequate trauma resources are present in less than 50% of the time. Multidisciplinary resources, quality improvement programs, protocols, and guidelines were deficient. CONCLUSIONS: A well-structured international teleconference can be used as a dynamic window of observation to evaluate and identify deficiencies in trauma care in the Latin American region. These findings can be used to formulate specific recommendations based on local resources. Furthermore, by raising local awareness, leaders could be identified to become the executors of more efficient healthcare policies that can potentially affect trauma care.

BACKGROUND: Early readmission (< 30 days) after percutaneous coronary intervention (PCI) is associated with a worse prognosis, but little is known regarding the causes and consequences of late readmission. The aim of the present study was to determine the incidence, causes, and prognosis of patients readmitted > 1 < 12-months after PCI (late readmission). METHODS: Single-center retrospective cohort study of 743 consecutive post-PCI patients. Patient characteristics and follow-up data were collected by reviewing their electronic medical records and from standardized telephone interviews performed at 1 year and at the end of follow-up. RESULTS: Of the 743 patients, 224 (30.14%) were readmitted 1-12 months after PCI, 109 due to chest pain (48.66%), and 115 for other reasons (51.34%). Hospital readmission was associated with lower survival rates of 77.6% vs. 98.3% at 24 months and 73.5% vs. 97.6% at 36 months (p < 0.001). Univariate predictors for late readmission were hypertension, older age, chronic kidney disease, lower left ventricular ejection fraction, and lower baseline hemoglobin concentration. Only baseline hemoglobin concentration was an independent predictor of late readmission (odds ratio: 0.867, 95% confidence interval: 0.778-0.966, p = 0.01). Readmission for chest pain portrayed a lower mortality rate compared to other causes, with survival rates of 90.2% vs. 50% at 36 months (p < 0.001). CONCLUSIONS: Late hospital readmission after PCI is associated with a worse prognosis and is related to patient comorbidities. Readmission for chest pain is common and portrayed a more favorable prognosis, similar to patients not readmitted. A readily available parameter, baseline anemia, was the main predictor of late readmission.

BACKGROUND: Nationally, the volume of geriatric falls with intracranial hemorrhage is increasing. Our institution began observing patients with intracranial hemorrhage, Glasgow Coma Scale of 14 or greater, and no midline shift or intraventricular hemorrhage with hourly neurologic examinations outside of the ICU in a high observation trauma (HOT) protocol. We first excluded patients on anticoagulants or antiplatelets (HOT I), then included antiplatelets and warfarin (HOT II), and finally, included direct oral anticoagulants (HOT III). Our hypothesis is that HOT protocol safely reduces ICU use and creates cost savings in this patient population. STUDY DESIGN: Our institutional trauma registry was retrospectively queried for all patients on HOT protocol. Patients were stratified based on date of admission (HOT I [2008-2014], HOT II [2015-2018], and HOT III [2019-2021]), and were compared for demographics, anticoagulant use, injury characteristics, lengths of stay, incidence of neurointervention, and mortality. RESULTS: During the study period, 2,343 patients were admitted: 939 stratified to HOT I, 794 to HOT II, and 610 to HOT III. Of these patients, 331 (35%), 554 (70%), and 495 (81%) were admitted to the floor under HOT protocol, respectively. HOT protocol patients required neurointervention in 3.0%, 0.5%, and 0.4% of cases in HOT I, II, and III, respectively. Mortality among HOT protocol patients was found to be 0.6% in HOT I, 0.9% in HOT II, and 0.2% in the HOT III cohort (p = 0.33). CONCLUSIONS: Throughout the study period ICU use decreased without an increase in neurosurgical intervention or mortality, indicating the efficacy of the HOT selection criteria in identifying appropriate candidates for stepdown admission and HOT protocol.

PURPOSE: To report modern outcomes of femtosecond laser-assisted cataract surgery (FS-LASIK) for the correction of moderate-to-high hyperopia (≥3.50 diopters [D] and ≤6.50 D), excluding low or very high hyperopia. SETTING: Vissum, Alicante, Spain. DESIGN: Monocentric retrospective case series study. METHODS: Visumax-500 kHz femtosecond laser and Amaris-750 excimer-laser were used. Eyes with at least 6 months of follow-up were included. 36-month data was collected when available. Primary outcome measure was short term efficacy and safety. Secondary outcome measure was long term stability. RESULTS: 6-month data of 92 eyes was collected (68 eyes at 36 months). Mean age was 34.6 ± 10.4 years. Mean treated sphere was 4.69 ± 0.87. Efficacy index was 0.91 and 0.90 at 6 months and 36 months respectively. Safety index was 1.00. Uncorrected distance visual acuity was 20/20 or better in 72%, postoperative spherical equivalent within 0.5 D in 80% (93% within 1 D), and loss of 1 line of corrected distance visual acuity (CDVA) occurred in 13% (2 or more lines in 0%). Gain of 1 or more CDVA lines occurred in 17%. A slight but significant regression was observed at 36 months. Postoperatively, 21.73% required flap lift for laser enhancement, and 11.95% an orthoptic visual rehabilitation due to accommodative disorders. CONCLUSIONS: Modern LASIK provides good efficacy and safety levels for the management of moderate to high hyperopia (up to +6.5 D), with levels close to those previously reported with refractive lens exchange for young hyperopia patients without presbyopia, where we defend the maintenance of LASIK as first line therapy. Risk of requiring a refractive enhancement or an orthoptic visual rehabilitation remains relevant and needs to be discussed with patients preoperatively.

PURPOSE: To evaluate clinical retinal optical image quality following implantation of an extended depth of focus intraocular lens (EDOF IOL) (Vivity; Alcon Laboratories, Inc), and to compare it with a monofocal and a trifocal IOL. METHODS: This prospective, comparative, case-control study included 88 eyes implanted with: (1) 19 monofocal IOLs (AcrySof SA60AT; Alcon Laboratories, Inc); (2) 38 EDOF IOLs (AcrySof IQ Vivity); and (3) 31 trifocal IOLs (AT LISA tri 839MP; Carl Zeiss Meditec AG). Total root mean square, ocular lower (LOA) and higher (HOA) order aberrations, point spread function (PSF) Strehl ratio (PSF with LOA), and PSF Strehl ratio excluding LOA (PSF without LOA) were analyzed using a Pyramidal WaveFront-based sensor aberrometer Osiris (Costruzione Strumenti Oftalmici) at two different pupil sizes (3 and 4 mm). RESULTS: The trifocal IOL showed the highest PSF without LOA at both pupil sizes (0.52 ± 0.12 and 0.31 ± 0.07, respectively), followed by the AcrySof SA60AT (0.39 ± 0.10 and 0.27 ± 0.07) and AcrySof IQ Vivity (0.34 ± 0.11 and 0.24 ± 0.09) (P < .001). The AcrySof IQ Vivity and monofocal IOLs were comparable (P > .05). Despite the comparable postoperative low spherical equivalent among the IOL groups, the AT LISA tri 839MP retinal image quality (PSF with LOA) was the most severely affected by such residual refractive errors (dropped to 0.26 ± 0.06 at 3 mm; P < .001) compared to the monofocal AcrySof SA60AT (0.24 ± 0.07 at 3 mm) and EDOF Acrysof IQ Vivity (0.23 ± 0.06 at 3 mm) groups. The PSF with LOA was comparable (P > .05) among the three groups at both the 3-and 4-mm pupil size. CONCLUSIONS: Although trifocal IOLs provided significantly better retinal image quality if influence of LOA is excluded, they also demonstrated to be the most sensitive to residual refractive errors. Both the EDOF Acrysof IQ Vivity and mono-focal AcrySof SA60AT IOLs showed a comparable retinal image quality, and they are also comparable with trifocal IOLs when considering the clinically real PSF (PSF with LOA).

Background: Intramural coronary hematoma (ICH) is an unusual cause of acute coronary syndrome, and it represents a diagnostic challenge, especially in young patients in which it is not considered among the differential causes of acute myocardial ischemia. Clinical case: 40-year-old female, with type 2 diabetes and no other cardiovascular risk factors, who assisted to the Emergency Room with chest pain. In her first evaluation, electrocardiographic abnormalities, and troponin I elevation were found. A cardiac catheterization was performed, in which a proximal obstruction of the left anterior descending artery was observed, and then an optical coherence tomography (OCT) confirmed the presence of an ICH without a dissection flap. A stent was implanted in the obstruction area, with adequate angiographic outcome. The patient had a satisfactory evolution and was discharged to home without evidence of systolic dysfunction and is free of cardiovascular symptoms at 6-month follow-up. Conclusions: ICH must be considered within the differential diagnosis of acute myocardial ischemia in young patients, especially females. Intravascular image diagnosis is essential for the adequate diagnosis and treatment. Treatment must be individualized considering the extent of ischemia.
Introducción: el hematoma intramural coronario (HIC) es una causa poco frecuente de síndrome isquémico coronario agudo y representa un reto diagnóstico, en especial en pacientes jóvenes en los que puede llegar a no ser contemplado dentro de las causas de isquemia cardiaca no ateroesclerótica. Caso clínico: mujer de 40 años, con diabetes tipo 2 y sin otro factor de riesgo cardiovascular, quien acudió al Servicio de Urgencias manifestando dolor torácico. En su evaluación inicial se encontraron alteraciones en el electrocardiograma y elevación de troponina I. Se decidió la realización de coronariografía donde se observó lesión severa de la arteria descendente anterior. El estudio fue complementado con una tomografía de coherencia óptica intracoronaria, la cual confirmó la presencia de HIC sin disección, por lo que se decidió implantar un stent en el segmento arterial afectado con resultado angiográfico exitoso. La convalecencia posterior evolucionó sin complicaciones, lo que posibilitó su egreso a domicilio sin disfunción sistólica en el ecocardiograma y con seguimiento sin eventualidades a los 6 meses. Conclusiones: el HIC es una entidad que debe ser considerada como una causa posible de isquemia miocárdica aguda en pacientes jóvenes y que requiere de la complementación diagnóstica con estudios de imagen intravascular. Su tratamiento debe ser individualizado en el contexto de la extensión de la isquemia.

BACKGROUND: Prehospital identification of the injured patient likely to require emergent care remains a challenge. End-tidal carbon dioxide (ETCO2) has been used in the prehospital setting to monitor respiratory physiology and confirmation of endotracheal tube placement. Low levels of ETCO2 have been demonstrated to correlate with injury severity and mortality in a number of in-hospital studies. We hypothesized that prehospital ETCO2 values would be predictive of mortality and need for massive transfusion (MT) in intubated patients. METHODS: This was a retrospective multicenter trial with 24 participating centers. Prehospital, emergency department, and hospital values were collected. Receiver operating characteristic curves were created and compared. Massive transfusion defined as >10 U of blood in 6 hours or death in 6 hours with at least 1 U of blood transfused. RESULTS: A total of 1,324 patients were enrolled. ETCO2 (area under the receiver operating characteristic curve [AUROC], 0.67; confidence interval [CI], 0.63-0.71) was better in predicting mortality than shock index (SI) (AUROC, 0.55; CI, 0.50-0.60) and systolic blood pressure (SBP) (AUROC, 0.58; CI, 0.53-0.62) (p < 0.0005). Prehospital lowest ETCO2 (AUROC, 0.69; CI, 0.64-0.75), SBP (AUROC, 0.75; CI, 0.70-0.81), and SI (AUROC, 0.74; CI, 0.68-0.79) were all predictive of MT. Analysis of patients with normotension demonstrated lowest prehospital ETCO2 (AUROC, 0.66; CI, 0.61-0.71), which was more predictive of mortality than SBP (AUROC, 0.52; CI, 0.47-0.58) or SI (AUROC, 0.56; CI, 0.50-0.62) (p < 0.001). Lowest prehospital ETCO2 (AUROC, 0.75; CI, 0.65-0.84), SBP (AUROC, 0.63; CI, 0.54-0.74), and SI (AUROC, 0.64; CI, 0.54-0.75) were predictive of MT in normotensive patients. ETCO2 cutoff for MT was 26 mm Hg. The positive predictive value was 16.1%, and negative predictive value was high at 98.1%. CONCLUSION: Prehospital ETCO2 is predictive of mortality and MT. ETCO2 outperformed traditional measures such as SBP and SI in the prediction of mortality. ETCO2 may outperform traditional measures in predicting need for transfusion in occult shock. LEVEL OF EVIDENCE: Diagnostic test, level III.

BACKGROUND: For hospital accreditation and health promotion reasons, we examined whether the 22-item Job Content Questionnaire (JCQ) could be applied to evaluate job strain of individual hospital employees and to determine the number of factors extracted from JCQ. Additionally, we developed an Excel module of self-evaluation diagnostic system for consultation with experts. METHODS: To develop an Excel-based self-evaluation diagnostic system for consultation to experts to make job strain assessment easier and quicker than ever, Rasch rating scale model was used to analyze data from 1,644 hospital employees who enrolled in 2008 for a job strain survey. We determined whether the 22-item Job Content Questionnaire (JCQ) could evaluate job strain of individual employees in work sites. The respective item responding to specific groups' occupational hazards causing job stress was investigated by using skewness coefficient with its 95% CI through item-by-item analyses. RESULTS: Each of those 22 items on the questionnaire was examined to have five factors. The prevalence rate of Chinese hospital workers with high job strain was 16.5%.

INTRODUCTION: Despite its shortcomings, trauma-related injury severity score (TRISS) correlates well with mortality in large trauma datasets. The aim of this study was to determine if TRISS correlates with morbidity and hospital lengths of stay using data from an institutional registry at a Level I Trauma Center. We hypothesized that higher TRISS correlates with increased complications and longer hospital stays. METHODS: A retrospective review of our institutional registry was performed, examining all trauma admissions between January 1999 and June 30, 2015. Out of a total of 32,026 patient records, TRISS data were available in 23,205 cases. Abstracted data included patient age, gender, ISS, TRISS, presence of complication, Glasgow Coma Scale (GCS), hospital length of stay, intensive care unit LOS, step-down unit LOS, functional independence measure, and 30-day mortality. RESULTS: TRISS was highly predictive of mortality, with the AUC value of 0.95 (95% confidence interval 0.936-0.954, P < 0.01) compared to ISS (AUC 0.794), GCS (AUC 0.827), and age (AUC 0.650). TRISS also performed better than the other variables in terms of the ability to predict morbidity events (AUC 0.813). TRISS was comparable to ISS in terms of prediction of ICU admission (AUC 0.801 versus 0.811, respectively). After correcting for patient age and gender, higher TRISS significantly correlated with longer hospital stays . CONCLUSIONS: Despite previous criticisms, we found that TRISS is superior to ISS for mortality and morbidity prediction. TRISS correlated significantly with a hospital, step down, and ICU lengths of stay using a large administrative dataset.
RESUMO
Severe COVID-19 disease is associated with an increase in pro-inflammatory markers, such as IL-1, IL-6, and tumor necrosis alpha, less CD4 interferon-gamma expression, and fewer CD4 and CD8 cells, which increase the susceptibility to bacterial and fungal infections. One such opportunistic fungal infection is mucormycosis. Initially, it was debated whether a person taking immunosuppressants, such as corticosteroids, and monoclonal antibodies will be at higher risk for COVID-19 or whether the immunosuppresive state would cause a more severe COVID-19 disease. However, immunosuppressants are currently continued unless the patients are at greater risk of severe COVID-19 infection or are on high-dose corticosteroids therapy. As understood so far, COVID-19 infection may induce significant and persistent lymphopenia, which in turn increases the risk of opportunistic infections. It is also noted that 85% of the COVID-19 patients' laboratory findings showed lymphopenia. This means that patients with severe COVID-19 have markedly lower absolute number of T lymphocytes, CD4+T and CD8+ T cells and, since the lymphocytes play a major role in maintaining the immune homeostasis, the patients with COVID-19 are highly susceptible to fungal co-infections. This report is intended to raise awareness of the importance of early detection and treatment of mucormycosis and other fungal diseases, such as candidiasis, SARS-CoV-2-associated pulmonary aspergillosis, pneumocystis pneumonia and cryptococcal disease, in COVID-19 patients, to reduce the risk of mortality.
RESUMO
BACKGROUND: Alcohol (EtOH) intoxication is common among trauma patients. While providers are familiar with the clinical aspects of acute EtOH intoxication, few studies have investigated the effects that EtOH levels may have on common laboratory markers. The aim of this study was to identify hematologic and serum chemistry parameters that may be affected by the blood alcohol concentration (BAC), hypothesizing that BAC influences both comprehensive blood count (CBC) and comprehensive serum chemistry (CSC) components. METHODS: We performed an IRB-exempt institutional registry review of all trauma patients who had serum EtOH levels measured between January 2009 and June 2015. Data for each patient included: patient demographics, BAC determinations (g/dL), injury mechanism/severity information (ISS), hematologic parameters included in a CBC (hemoglobin, hematocrit, white blood cell [WBC] count, and platelet count), and CSC panel components (sodium, potassium, chloride, bicarbonate, blood urea nitrogen [BUN], creatinine, glucose, and hepatic function tests). Laboratory markers were contrasted across predefined categories of BAC: <0.10%, 10%-15%, 15%-20%, and >20%. Statistical comparisons were performed using SPSS 18 Software, employing analysis-of-covariance with adjustments performed for the patient demographics and injury characteristics. Statistical significance was set at α = 0.005. RESULTS: A total of 2167 patient records were analyzed. After adjusting for patient age, gender, and ISS, increasing BAC correlated with 4.8% increase in hemoglobin and 32.5% higher hematocrit (both P < 0.001), as well as a 27.8% decrease in WBC count. There were also statistically significant differences between low (<0.10%) and high (>0.20%) BAC groups across multiple CSC parameters, with largest impact on BUN (32.2% decrease); creatinine (31.5% decrease); and glucose (13.6% decrease) values. Elevated BAC (>0.20 g/dL) was also associated with 81.8% increase in total bilirubin, and hepatic transaminases were elevated among patients with BAC >0.10. CONCLUSION: Due to the paucity of literature relating to the effects of BAC on serum hematologic and biochemical markers in acute trauma, this study provides a foundation for further exploration of these relationships and their clinical impact. More specifically, we found that BAC levels significantly influenced key laboratory markers, suggesting that acute EtOH intoxication may lead to hematologic and CSC changes that are potentially important in acute trauma management by frontline clinical staff.
RESUMO
Severe polytrauma involving multiple organ systems presents a significant challenge to any trauma center. We present a case of a patient presenting simultaneously with a type B aortic dissection, bilateral internal carotid dissections, a brachiocephalic artery dissection, and a splenic laceration among other injuries. In this patient with both solid organ injury and vascular trauma, we discuss how multidisciplinary collaboration was required to prioritize treatment goals and determine the proper initiation of antiplatelet and anticoagulation therapies.
RESUMO
Norovirus (NoV) is an important etiological agent of diarrhea in children and adults. In Mexico, NoV screening is not routinely performed. NoV is highly infectious and is responsible for massive outbreaks due to the consumption of contaminated food. The study was a cross-sectional design. Samples of diarrheal stools were collected from (62) children and (38) adults with acute gastroenteritis during 2013-2014. The circulating genogroups of NoV were detected by amplifying the RdRp gene fragment, and for the genotyping, the capsid and polymerase fragments were sequenced. Seventy-seven percent of the analyzed samples were positive for NoV. Genotyping was possible for 51 samples; for polymerase GII.P2, GII.P31, GII.P4, GII.P7, GII.P40, and GI.P14 were identified, whereas for capsid, genotypes GI.3, GII.2, GII.4, GII.5, GII.14, and GII.17. In conclusion, there is a high prevalence of gastroenteritis due to NoV in the northwest of Mexico, including genotypes that have not been reported previously in Mexico.
