La viruela de mono. ¿Una zoonosis emergente? / Monkeypox virus. An emergent zoonosis?

Resumen La viruela de mono es una enfermedad zoonótica propia de roedores y primates no humanos que producen casos esporádicos de monopox, el cual se caracteriza por lesiones exantemáticas en la piel. La viruela del mono es endémica en países del África Central y del Oeste, especialmente en la República Democrática del Congo. En 2003 se detectó por primera vez en el occidente y en el 2022 reaparece en Estados Unidos y otros países del mundo. Aunque cualquier persona que se exponga al virus puede desarrollar la enfermedad, este brote se ha caracterizado por presentar características epidemiológicas distintas ya que los grupos de riesgo más frecuente son los de los hombres que tienen sexo con hombres. Los nuevos brotes de esta enfermedad se han caracterizado por cambios importantes en la presentación clínica ya que el exantema no se presenta generalizado. Por el contrario, ha mostrado muchas variantes como la presentación de lesiones vesiculares únicas en la región genital, lo que hace difícil su diagnóstico clínico. Por ser una enfermedad emergente y presentar cambios en su comportamiento es importante estar consultando las recomendaciones de las organizaciones competentes para el manejo, tratamiento y diagnóstico de esta enfermedad.

Abstract Human monkeypox is a rare viral zoonosis endemic to central and western Africa. It was detected for the first time in the western Hemisphere in 2003. Recently it has re-emerged in USA and has spread rapidly to many countries of the world. Even though any person could contract the disease if expose to it, the populations most vulnerable to the infection are homosexuals, bisexuals and men that have sex with men. The virus produces an exanthem in the skin, which is clinically indistinguishable from other pox-like illnesses, particularly smallpox and chickenpox. Furthermore, clinical findings in recent studies have reported single vesicular lesions in the anogenital areas making the laboratory diagnosis an essential tool to be able to differentiate it from other venereal diseases. Since Human monkeypox is an emergent disease that presents very important epidemiological and clinical features, different from past outbreaks, it is recommended to be in constant communication with the competent health organizations and be aware of changes in case definitions, treatment and diagnostic procedures.

Blasting the myth of predictive INR changes related to plasma transfusion: an academic institution's experience

Abstract Introduction Plasma transfusion is a common therapeutic strategy used to lower international normalized ratio (INR) values in the non-emergent setting. However, due to lack of evidence of its efficacy, standardized guidelines for this practice have not been well established. Methods This retrospective observational cohort study analyzed 276 inpatient encounters that involved plasma transfusions focusing on change in INR values from pre- to post-transfusion, with respect to the following predictor variables: vitamin K co-administration, number of plasma units transfused, order indication and body mass index (BMI). Results The overall average change in the INR was 1.35. Patients who received vitamin K showed an average change of 2.51, while patients that did not receive vitamin K demonstrated an average change of 0.70. Increased numbers of plasma units transfused showed benefit up to three-unit orders. Greater decreases in the INR were observed for patients requiring plasma for anticoagulation reversal or active bleeding. There was no significant difference in the change in INR based on the BMI. By multivariate and regression analyses, the stepwise addition of each successive predictor variable demonstrated an increase in the shared variance in the outcome of the post-transfusion INR: the pre-transfusion INR and vitamin K co-administration alone was not significant (p= 0.45); the additional number of plasma units transfused was significant (R² = 0.13, p < 0.001), and; the subsequent additional plasma order indications (R² = 0.19, p < 0.001) and BMI (R² = 0.18, p < 0.001) were increasingly significant. Conclusion Taking into consideration the combination of multiple predictive factors may aid in a more efficient use of plasma products.

Animal model-based simulation training for three emergent and urgent operations of penetrating thoracic injuries / 中华创伤杂志(英文版)

PURPOSE@#To develop animal models of penetrating thoracic injuries and to observe the effects of the animal model-based training on improving the trainees' performance for emergent and urgent thoracic surgeries.@*METHODS@#With a homemade machine, animal models of lung injuries and penetrating heart injuries were produced in porcine and used for training of chest tube drainage, urgent sternotomy, and emergent thoracotomy. Coefficient of variation of abbreviated injury scale and blood loss was calculated to judge the reproducibility of animal models. Five operation teams from basic-level hospitals (group A) and five operation teams from level III hospitals (group B) were included to be trained and tested. Testing standards for the operations were established after thorough literature review, and expert questionnaires were employed to evaluate the scientificity and feasibility of the testing standards. Tests were carried out after the training. Pre- and post-training performances were compared. Post-training survey using 7-point Likert scale was taken to evaluate the feelings of the trainees to these training approaches.@*RESULTS@#Animal models of the three kinds of penetrating chest injuries were successfully established and the coefficient of variation of abbreviated injury scale and blood loss were all less than 25%. After literature review, testing standards were established, and expert questionnaire results showed that the scientific score was 7.30 ± 1.49, and the feasibility score was 7.50 ± 0.89. Post-training performance was significantly higher in both group A and group B than pre-training performance. Post-training survey showed that all the trainees felt confident in applying the operations and were generally agreed that the training procedure were very helpful in improving operation skills for thoracic penetrating injury.@*CONCLUSIONS@#Animal model-based simulation training established in the current study could improve the trainees' performance for emergent and urgent thoracic surgeries, especially of the surgical teams from basic-level hospitals.

Análisis retrospectivo de un protozoo emergente en México: Blastocystis spp

Blastocystis spp. es el protista intracelular que en los últimos años ha infectado a más de mil millones de personas a nivel mundial. Sin embargo, el aumento en la prevalencia en México y su potencial patógeno son inciertos, por lo que este microorganismo aún se encuentra bajo investigación. Principalmente a nivel pediátrico, la blastocistosis es estudiada con mayor atención, debido a que destaca sobre otros agentes en diversos estudios realizados mundialmente y en México. El objetivo de este trabajo fue mediante revisión bibliográfica, evidenciar la frecuencia y su transición parasitaria como el agente más prevalente en la actualidad, pese a que no se asocia a sintomatología clínica.

Blastocystis spp. is the intracellular protist that in recent years has infected more than a billion people worldwide. However, the increase in prevalence in Mexico and its pathogenic potential are uncertain, so this microorganism is still under investigation. Mainly at the pediatric level, blastocystosis is studied with greater attention, due to the fact that it stands out over other agents in various studies carried out worldwide and in Mexico. The objective of this work was to show the frequency and its parasitic transition as the most prevalent agent today through a bibliographic review, despite the fact that it is not associated with clinical symptoms.

Perioperative Outcomes in Pregnant Women Who Underwent Surgery for Adnexal Torsion / Resultados perioperatórios em mulheres grávidas submetidas a cirurgia para torção anexial

Abstract Objective To evaluate clinical characteristics, maternal and fetal outcomes in pregnant women who underwent surgery for adnexal torsion (AT). Methods All patients, who underwent surgical operation due to AT during pregnancy at the Department of Obstetrics and Gynecology, School of Medicine, Ege University between 2005 and 2020 were retrospectively investigated. Main clinical and perioperative outcomes were evaluated. Results A total of 21 patients who underwent surgery due to AT during pregnancy were included. Of all patients, 61.9% underwent laparoscopy and the remaining 38.1% underwent laparotomy. The most common surgical procedure was adnexal detorsion in both groups (48%). Mean gestational age at the time of diagnosis, duration of surgery and hospitalization were significantly lower in the laparoscopy group, when compared with the laparotomy group (p=0.006, p=0.001, and p=0.001, respectively.) One of the patients had an infection during the postoperative period. Spontaneous abortion was only observed in one case. Conclusion It can be concluded that the surgical intervention implemented for the exact diagnosis and treatment of AT (laparotomy or laparoscopy) did not have an unfavorable effect on pregnancy outcomes such as abortion, preterm delivery, and fetal anomaly. However, laparoscopy may be superior to laparotomy in terms of advantages.

Clinical practice and prognosis of emergent transcatheter aortic valve replacement / 中华急诊医学杂志

Objective:To evaluate the effectiveness and prognosis of emergent transcatheter aortic valve replacement (TAVR) and to provide standardized procedural suggestion for the development of emergent TAVR in China.Methods:From January 2020 to April 2021, 12 patients who underwent emergent or salvage TAVR in the Second Affiliated Hospital Zhejiang University School of Medicine were retrospectively enrolled from the TORCH registry (Transcatheter Aortic Valve Replacement Single Center Registry in Chinese Population, a prospective cohort study; NCT02803294). Baseline, periprocedural and 30-day follow up data were collected. Post-operative data were compared with pre-operative data using Paired-Samples test.Results:Patients’ median Society of Thoracic Surgeons score (STS score) was 15.432%. There was a significant decrease of mean gradient after emergent TAVR procedure (1.69 m/s vs. 4.90 m/s, P<0.01). During the 30-day follow up, there were 1 patient (8.3%) died and 2 patients received permanent pacemaker implantation. No disabling stroke, acute kidney injury, major vascular complication occurred during the first month after emergent TAVR. Among the survival patients, there was a significant releasing of heart failure symptoms to New York Heart Association function stage Ⅰ/Ⅱ in 81.8% patients at 30-day follow up. Left ventricular ejection fraction also improved significantly from (47.4±9.5)% to 58.8±8.0% ( P= 0.026). The mean gradient were (1.57±0.30) cm 2 and no patients had a moderate or severe paravalvular leakage. Besides, a significant decrease of pro-B-type natriuretic peptide (1 089.9 pg/mL vs. 12 215.5 pg/mL , P=0.001) and troponin T (0.020 ng/mL vs. 0.337 ng/mL, P=0.003) were found at 30 days after emergent TAVR. Conclusions:For patients with severe aortic stenosis and acute cardiac decompensated, emergent TAVR is a safe and effective rescue treatment.

El desafío de las enfermedades (re)emergentes, los límites de la respuesta biomédica y el nuevo paradigma de salud global / The challenge of (re)emerging diseases, the limits of the biomedical response and the new paradigm of global health

Resumen Las "enfermedades infecciosas emergentes y reemergentes" constituyen una creciente amenaza para la hegemonía de la biomedicina, al suscitar no pocos interrogantes sobre la idoneidad de su discurso y prácticas para afrontar el desafío global que representan. Se analiza el proceso de construcción de esta nueva categoría nosológica, y se examinan ejemplos destacados del impacto de las enfermedades (re)emergentes en la salud pública, la seguridad alimentaria y el desarrollo humano a escala global. Se refiere a prácticas irresponsables de sectores de la industria farmacéutica y agropecuaria, determinantes en su desencadenamiento y diseminación; y a algunos fallos cruciales de enfoque y manejo de los tiempos en las políticas de salud global en relación al VIH/sida con desastrosas consecuencias para el África subsahariana.

Abstract "Emerging and reemerging infectious diseases" pose a growing threat to the hegemony of biomedicine, raising questions about whether its discourse and practices can handle the global challenge they represent. The construction of this new nosological category is analyzed in this article, which examines some notable examples of the impact of (re)emerging diseases on public health, food security and human development on a global scale. It discusses irresponsible practices by sectors of the pharmaceutical and agricultural industries which led to the emergence and spread of these diseases; and points to some crucial failures of approach and time management in global health policies on HIV/AIDS, with disastrous consequences for sub-Saharan Africa.

Clinical characteristics of critically ill pregnant women with different admission methods to intensive care unit: data analysis from 2006 to 2019 in the university hospital / 中华危重病急救医学

Objective:To compare the clinical characteristics of critically ill pregnant women admitted to the intensive care unit (ICU) with different admission methods, in order to make more effective and rational use of ICU resources.Methods:A retrospective study was conducted. The clinical data of critically ill pregnant women admitted to ICU of Peking University Third Hospital from January 2006 to July 2019 were analyzed. According to the admission mode to ICU, the pregnant women were divided into emergency admission group (transferred to ICU on the same day or the next day due to critical illness) and planned admission group (transferred to ICU 2 days after admitting in obstetric ward). The clinical characteristics of ICU critical pregnant women, such as the incidence, causes of admission, severity of the disease, main treatment measures, mortality, and medical expenses were collected, and a comparative analysis between the two groups was performed.Results:During the nearly 14 years, a total of 576 critical pregnant women in ICU were enrolled, accounting for 0.8% (576/71 790) of the total number of obstetric inpatients and 4.6% (576/12 412) of the total number of ICU inpatients. Seven maternal deaths accounted for 1.2% of all critically pregnant women transferred to ICU, and the overall mortality of pregnant women was 10/100 thousand. Of the 576 critically pregnant women, there were 327 patients (56.8%) in the emergency admission group and 249 patients (43.2%) in the planned admission group. Compared with the planned admission group, the proportion of elective cesarean section in the emergency admission group was significantly lower (17.7% vs. 94.0%, P < 0.01), and the proportion of emergency cesarean section was significantly higher (65.1% vs. 2.4%, P < 0.01), the acute physiology and chronic health evaluation (APACHE Ⅱ, APACHE Ⅲ) scores, simplified acute physiology score Ⅱ (SAPS Ⅱ) and Marshall score were significantly higher [APACHE Ⅱ score: 6.0 (4.0, 9.8) vs. 4.0 (3.0, 7.0), APACHE Ⅲ score: 14.0 (11.0, 20.3) vs. 12.0 (9.0, 16.0), SAPS Ⅱ score: 8 (0, 12) vs. 3 (0, 8), Marshall score: 2 (1, 4) vs. 1 (1, 3), all P < 0.01]. The length of ICU stay in the emergency admission group was significantly longer than that in the planned admission group [days: 2 (1, 5) vs. 2 (1, 3), P < 0.01], and the total length of hospital stay was significantly shorter [days: 9 (7, 13) vs. 13 (10, 18), P < 0.01]. Both in the emergency admission group and the planned admission group, obstetric factors were the main reason for admission, 60.9% (199/327) and 70.3% (175/249), respectively. The proportion of postpartum hemorrhage was the highest [35.2% (115/327) and 57.0% (142/249)], followed by preeclampsia/eclampsia [7.0% (23/327) and 7.6% (19/249)]. Only 7 of the 19 critically pregnant women with puerperal infection were planned admission. All 21 patients with acute fatty liver of pregnancy (AFLP) during pregnancy were emergency admission. Among the emergency and planned admission patients, 73 patients (22.3%) and 42 patients (16.9%) required mechanical ventilation (duration of mechanical ventilation > 24 hours), 99 patients (30.3%) and 35 patients (14.1%) needed vasoactive agents, 67 patients (20.5%) and 20 patients (8.0%) received hemodynamic monitoring, and 123 patients (37.6%) and 154 patients (61.8%) were given anticoagulation therapy, respectively. In terms of severity score of critical pregnant women, there were significant differences in APACHE Ⅱ, APACHE Ⅲ, SAPS Ⅱ and Marshall scores of pregnant women with different diseases. Among them, the APACHE Ⅲ, SAPS Ⅱ and Marshall scores of AFLP were the highest [21.0 (15.0, 32.5), 12.0 (6.0, 16.5) and 6.0 (3.5, 8.0), respectively]. The APACHE Ⅱ and APACHE Ⅲ scores of postpartum hemorrhage were the lowest [4.0 (3.0, 7.0), 12.0 (10.0, 16.0)]. The SAPS Ⅱ score of pneumonia was the lowest [2.0 (0, 14.0)]. The Marshall score for puerperal infection was the lowest [1.0 (0, 3.0)]. In terms of the total medical expenses, the cost in the emergency admission group was significantly lower than that in the planned admission group [10 thousand Yuan: 3.1 (2.0, 4.7) vs. 4.1 (2.9, 5.8), P < 0.05]. Conclusions:Compared with the critically ill pregnant women who planned to be admitted to ICU, the patients emergency admitted to ICU were more complicated and urgent, and the severity of the condition was scored higher. At present, the severity scoring system commonly used in ICU can only partly evaluate the severity of critically ill pregnant women, therefore, it is necessary to design the specific severity scoring system for critically ill pregnant women to effectively and rationally use the precious ICU resources.

Comparison of clinical results of decompression/fusion surgery for paralysis caused by metastatic spinal tumors of unknown versus known origin / Journal of Rural Medicine

Objective: Whether or not emergent decompression/fusion surgery for paralysis caused by metastatic spinal tumors of unknown origin improves patient neurological outcome and survival remains unclear. This study aimed to evaluate the clinical outcomes of emergent decompression/fusion surgery for paralysis caused by spinal tumors of unknown or not previously diagnosed origin.Patients and Methods: Data from the medical records of 11 patients with spinal tumors of unknown origin (study group) were compared with those of 15 patients with metastatic spinal tumors of known origin (control group). The outcome measures were postoperative performance status, motor function evaluated with the Frankel grade, and actual survival after surgery as compared with the estimated survival calculated using the Tokuhashi score. χ2 analyses were performed to evaluate differences between the groups.Results: The mean performance status was 3.6 preoperatively, which improved to 2.9 postoperatively (P<0.05), in the unknown origin group and 3.6 preoperatively, which improved to 2.7 postoperatively (P<0.05), in the control group. Seven patients (64%) in the unknown origin group showed improvement in paralysis by ≥1 Frankel grade. By contrast, only 4 patients (27%) in the control group showed improvement in paralysis. The unknown origin group tended to show better improvement (P=0.05). All the patients in the unknown origin group underwent adjuvant therapy after definitive diagnosis following surgery. The unknown origin group showed a slight tendency toward better survival than toward the estimated survival.Conclusion: Emergent decompression/fusion surgery for patients with paralysis caused by metastatic tumors of unknown origin is potentially useful for diagnosing tumor origin and improving neurological outcomes and performance status, and thus for extending survival.

Mayaro fever: A brief review on the immune profile

Mayaro virus is an emergent alphavirus that infects humans, leading to Mayaro fever. Approximately fifty percent of infected patients develop arthritis symptoms in the recovery phase, a phase that can last up to a year. The literature about Mayaro virus infection and its immune response is scarce, which may hamper the development of treatment strategies. We summarize changes in cytokines and chemokines in the acute and recovery phase in Mayaro virus infected patients, and relate this molecular characterization with the immune response. VEGF and IL-12/p70 show pronounced changes in patients in the acute phase, suggesting the development of cellular immunity and Th1 response. IL-6, IL-7, CXCL8/IL-8, IL-13, IL-17, and IFN-γ are elevated in patients with arthritis symptoms in the long-term recovery phase, which may be related to the continuous inflammatory process, a possible Th2 inhibiting and promoting Th17 process. Although few studies discuss the issue, with a small number of patients and different backgrounds, inflammatory and immune response and manifestations seem to be closely linked. This information may help to develop the appropriate treatment strategies in Mayaro virus infection. Therefore, we analyzed and summarized data available in literature.

Experimental Frog Virus 3 infection using Brazilian strain: amphibians susceptibility / Infecção experimental utilizando estirpe brasileira de Frog Virus 3: suceptibilidade de anfíbios

An alarming number of global warnings concerning amphibian mortality outbreaks have been released in recent years. Emerging diseases stand out as the main potential causes. Ranavirus is a worldwide-spread highly infectious disease capable of affecting even other ectothermic animals such as fish and reptiles. One major issue regarding this pathology is the lack of clinical signs before it leads up to death. Aiming at having a better understanding of anurans susceptibility, this study analyzed bullfrog (Lithobates catesbeianus) survival rate, when challenged with three doses of a Brazilian strain of Frog Virus 3 (FV3). The qPCR analysis indicated a low infectivity rate in these animals both as larvae and as adults. To elucidate the results, the following hypothesis was performed: 1) The amount of inoculum used on the frogs was insufficient to trigger an infection; 2) For the FV3 to produce clinical signs in this species, there is the need for a cofactor; 3) The animals did undergo FV3 infection but recovered in the course of the experiment, and 4) The inoculum utilized might have been low-virulence. Finally, the presence of actual clinical signs of ranavirus is discussed, with the more likely hypothesis.(AU)

Um número alarmante de notificações globais sobre surtos de mortalidade de anfíbios tem sido realizado nos últimos anos. As doenças emergentes destacam-se como as principais causas potenciais. O ranavírus é uma doença altamente infecciosa disseminada em todo o mundo, capaz de afetar até outros animais ectotérmicos como peixes e répteis. Uma questão importante em relação a essa patologia é a falta de sinais clínicos antes de levar à morte. Com o objetivo de compreender melhor a suscetibilidade dos anuros, o presente trabalho analisou a taxa de sobrevivência de rãs-touro (Lithobates catesbeianus), desafiadas com três doses de uma estirpe brasileira do Frog virus 3 (FV3). A análise de qPCR indicou baixa taxa de infectividade nesses animais, tanto como larvas quanto como adultos. Procurando esclarecer os resultados, foram formuladas as seguintes hipóteses: 1) A quantidade de inóculo aplicada nas rãs foi insuficiente para desencadear uma infecção; 2) Para que o FV3 dê sinais clínicos nesta espécie, é necessário um cofator; 3) Os animais sofreram infecção por FV3, mas se recuperaram no decorrer do experimento, e 4) O inóculo utilizado pode ter sido de baixa virulência. Finalmente, foi discutida a presença de sinais clínicos reais de ranavírus e levantada a hipótese mais provável(AU)

The Contribution of Emergent Literacy Skills for Early Reading and Writing Achievement / Contribuição das Habilidades de Letramento Emergente para as Competências Iniciais de Leitura e Escrita / Contribución de las Habilidades de Alfabetización Temprana a las Competencias Iniciales de Lectura y Escritura

Abstract Studies in the English language suggest that emergent literacy skills promote success in literacy. This longitudinal study investigated whether and which emergent literacy skills contribute to initial reading and writing performance in a sample of 34 Brazilian children from public schools. The participants underwent tests on phonological awareness, oral comprehension, vocabulary and knowledge of letters at the end of Early Childhood Education. The participants' skills in writing and reading words as well as reading comprehension were evaluated in the 1st year of elementary school. Data were analyzed using correlation and regression analysis. Results showed that emergent literacy skills presented significant positive correlations with reading and writing performance. Multiple regression analyses indicated significant and independent contributions of phonological awareness and knowledge of letters for writing, however, only phonological awareness significantly and independently contributed to reading of words and reading comprehension skills. It was concluded that emergent literacy skills related to the coding domain are the most important for literacy.

Resumo Estudos em língua inglesa sugerem que as habilidades de letramento emergente favorecem o sucesso na alfabetização. Este estudo longitudinal investigou se e quais habilidades de letramento emergente contribuem para as competências iniciais de leitura e escrita de uma amostra de 34 crianças brasileiras, alunas da rede pública de ensino. Ao final da Educação Infantil, as crianças foram submetidas a testes de consciência fonológica, compreensão oral, vocabulário e conhecimento das letras. No 1º ano do Ensino Fundamental, foram avaliadas as competências de escrita e leitura de palavras, bem como de compreensão em leitura dos participantes. Os dados foram analisados através de técnicas correlacionais e de análise de regressão. Os resultados mostraram que todas as habilidades de letramento emergente avaliadas apresentaram correlações positivas significativas com o desempenho nos testes de leitura e escrita. Contudo, análises de regressão múltipla indicaram contribuição significativa e independente apenas da consciência fonológica e do conhecimento de letras para a escrita; para as habilidades de leitura de palavras e compreensão em leitura, somente a consciência fonológica contribuiu de forma significativa e independente. Conclui-se que as habilidades de letramento emergente relacionadas ao domínio do código são as mais importantes para a alfabetização.

Blunt cardiac injury:experience in 43 cases treated operatively / 中华胸心血管外科杂志

Objective To explore early diagnosis， surgical intervention and efficacy for blunt cardiac injury. Methods 43 patients with blunt cardiac injury treated operatively were studied retrospectively in respect of sex, age, cause of injury, pre-operative diagnosis, operative time from injury, surgical procedures, and therapeutic efficacy. The study lasted for 15 years be-tween September 2003 and August 2018. The main cause of injury is road traffic accident with a rate of 48. 8％(21/43);and steering wheel injury accounted for 71. 4％(15/21). Preoperative diagnosis was based on computer scaning, echocardiography in 26 cases. In remaining 17, initial judgement of cardiac wound was done because of obvious cardiac tamponade, or massive hemothorax with shock;and was proved during emergent thoracotomy. Surgical intervention was started within one hour in cases of 27. 9％(12/43). Main procedures included pericardial decompression, clear off hemopericardium, and cardiorrhaphy in 36 cases;relief of pericardial herniation with strangulation of the heart in 3 cases, and repair of diaphragmatic hernia involving pericardium in 4 cases. Of all 43 cases, 7 cases underwent Emergent Department Thoracotomy( EDT) with a resuscitative rate of 42. 9％(3/7). Results Overall mortality rate was 32. 6％(14/43);4 cases died at EDT, 5 cases intraoperatively, and 5 cases postoperatively. The cause of deaths was directly related to BCI in 9 cases( associated with transected aorta in 1 case);and associated injuries in 5 cases including liver trauma ( 3 cases ) , brain trauma ( 1 case ) , and cervical spinal trauma ( 1 case) . In 4 of 29 survivors, intracardiac injury was proved by echocardiography postoperatively, including mitral valve in 2 ca-ses, tricuspid in 1 case, and ventricular septum in 1 case. Of these 4 cases 2 received valvuloplasty 2 weeks and 3 months after initial operation respectively;and other 2 restored spontaneously which were ensured by echocardiography. Postoperative com-plications included atelectasis in 3 and infectious endocarditis in 1 respectively. They were cured . All survivors were followed up from 6 to 36 months, with a normal cardiac function and healthy condition. Conclusion Early diagnosis and emergent tho-racotomy in time are essential to improve survival rate. Preoperative massive transfusion and pericardiocentesis are not advoca-ted. If it is necessary, EDT should be exercised decidedly.

Blunt cardiac injury: analysis of 348 patients / 中华急诊医学杂志

Objective@#To explore the early diagnosis, therapeutic methods and efficacy for blunt cardiac injury (BCI).@*Methods@#All BCI patients from September 2003 to August 2018 were studied retrospectively in respect of sex, age, cause of injury, diagnostic methods, therapeutic procedures, and outcome. The patients were divided into two groups: nonoperative group (n=305) and operative group (n=43). The two groups were compared and analyzed.@*Results@#Totally 348 BCI patients accounted for 18.3% of 1 903 patients with blunt thoracic injury (BTI), and the mortality rate was 10.1%. The main cause of injury was traffic accident with an incidence of 48.3%. The diagnostic methods included electrocardiogram (ECG), enzymes and troponin I, echocardiography, and CT scanning, or confirmed by emergency thoracatomy. In the nonoperative group, patients were mainly myocardial contusion, with a mortality rate of 6.9%. In the operative group, patients were mainly cardiac rupture and pericardial hernia, and the mortality was 32.6%. The incidence of negative ECG between the two groups was not significantly different (16.7% vs 11.6%, P>0.05). The incidence of shock and mortality in the operative group were significantly higher than those in the the nonoperative group (P<0.01). The number of death directly resulted from BCI in the operative group was greater than that in the nonoperative group (P<0.05).@*Conclusions@#For BTI patients, BCI must be highly suspected, and necessary examinations should be given. To manage myocardial contusion without surgery, it is necessary to protect the heart, alleviate edema of myocardium, and control arrhythmia with drugs. To deal with those patients requiring operation, early recognition and expeditious thoracotomy are essential.

Effects of cardiac rehabilitation combined with psychological invention on clinical efficacy in high-risk patients with acute myocardial infarction after emergent percutaneous coronary intervention / 中华行为医学与脑科学杂志

Objective@#To investigate the effects of stage I cardiac rehabilitation combined with structural psychological invention high-risk patients with acute myocardial infarction (AMI) treated by emergent percutaneous coronary intervention (PCI).@*Methods@#Totally 120 patients with AMI that received emergent PCI were randomized into experimental group(n=60) and control group(n=60). The experimental group started stage I cardiac rehabilitation combined with structural psychological invention after emergency PCI.The control group received routine treatment.Self-rating Anxiety Scale (SAS) and Self-rating depression Scale (SDS) scores were compared in both groups at before PCI and 1 week after PCI.Left ventricular ejection fraction (LVEF) and left ventricular end-diastolic diameter (LVEDD) were compared in both groups at before PCI and 1 week, 1 month and 6 months after PCI.The incidence of adverse cardiac events including cardiac death and recurrence myocardial infarction were compared between the two groups at 6 months after PCI.@*Results@#The SAS score in the experimental group (36.38±5.15) was lower than that in the control group (42.10±5.79) in 1 week after PCI (t=2.313, P<0.05). The SDS score in the experimental group(37.09±5.56) was lower than that in the control group (43.85±5.33) in 1 week after PCI (t=2.330, P<0.05). The LVEF in the experimental group( (45.08±4.41)%) was significantly higher than that in the control group ((42.81±3.83)%) in 1 week after PCI ( t=2.209, P<0.05). The LVEF in the experimental group ((48.93±4.39)%) was significantly higher than that in the control group ((44.61±4.35)%) in 1 month after PCI (t=2.224, P<0.05). The LVEDD in the experimental group ((54.74±4.01)mm) was significantly lower than that in the control group ((57.81±4.49)mm) in 1 month after PCI (t=2.413, P<0.05). The LVEDD in the experimental group ((52.21±2.82)mm) was significantly lower than that in the control group ((55.65±3.88)mm) in 6 month after PCI (t=2.297, P<0.05). And there were no significant difference between the two groups at other time point(all P>0.05). The follow-up results after 6 months showed that the experimental group (8.9%) had lower incidence of cardiac death than that in the control group (24.1%) (HR(95%CI): 0.317(0.128-0.835), P<0.05). The follow-up results after 6 months showed that the experimental group (14.2%) had lower incidence of recurrence myocardial infarction than that in the control group (42.2%) (HR(95%CI): 0.263(0.125-0.548), P<0.05).@*Conclusion@#Stage I cardiac rehabilitation improved the cardiac function in high-risk patients with AMI treated by emergent PCI and reduced the incidence of cardiac death and recurrence myocardial infarction.

Blunt cardiac injury: experience in 43 cases treated operatively / 中华胸心血管外科杂志

Objective@#To explore early diagnosis, surgical intervention and efficacy for blunt cardiac injury.@*Methods@#43 patients with blunt cardiac injury treated operatively were studied retrospectively in respect of sex, age, cause of injury, preoperative diagnosis, operative time from injury, surgical procedures, and therapeutic efficacy. The study lasted for 15 years between September 2003 and August 2018. The main cause of injury is road traffic accident with a rate of 48.8%(21/43); and steering wheel injury accounted for 71.4%(15/21). Preoperative diagnosis was based on computer scaning, echocardiography in 26 cases. In remaining 17, initial judgement of cardiac wound was done because of obvious cardiac tamponade, or massive hemothorax with shock; and was proved during emergent thoracotomy. Surgical intervention was started within one hour in cases of 27.9%(12/43). Main procedures included pericardial decompression, clear off hemopericardium, and cardiorrhaphy in 36 cases; relief of pericardial herniation with strangulation of the heart in 3 cases, and repair of diaphragmatic hernia involving pericardium in 4 cases. Of all 43 cases, 7 cases underwent Emergent Department Thoracotomy(EDT) with a resuscitative rate of 42.9%(3/7).@*Results@#Overall mortality rate was 32.6%(14/43); 4 cases died at EDT, 5 cases intraoperatively, and 5 cases postoperatively. The cause of deaths was directly related to BCI in 9 cases(associated with transected aorta in 1 case); and associated injuries in 5 cases including liver trauma(3 cases), brain trauma(1 case), and cervical spinal trauma(1 case). In 4 of 29 survivors, intracardiac injury was proved by echocardiography postoperatively, including mitral valve in 2 cases, tricuspid in 1 case, and ventricular septum in 1 case. Of these 4 cases 2 received valvuloplasty 2 weeks and 3 months after initial operation respectively; and other 2 restored spontaneously which were ensured by echocardiography. Postoperative complications included atelectasis in 3 and infectious endocarditis in 1 respectively. They were cured . All survivors were followed up from 6 to 36 months, with a normal cardiac function and healthy condition.@*Conclusion@#Early diagnosis and emergent thoracotomy in time are essential to improve survival rate. Preoperative massive transfusion and pericardiocentesis are not advocated. If it is necessary, EDT should be exercised decidedly.

Blunt cardiac injury: analysis of 348 patients / 中华急诊医学杂志

Objective To explore the early diagnosis,therapeutic methods and efficacy for blunt cardiac injury (BCI).Methods All BCI patients from September 2003 t9 August 2018 were studied retrospectively in respect of sex,age,cause of injury,diagnostic methods,therapeutic procedures,and outcome.The patients were divided into two groups:nonoperative group (n=305) and operative group (n=43).The two groups were compared and analyzed.Results Totally 348 BCI patients accounted for 18.3％ of 1 903 patients with blunt thoracic injury (BTI),and the mortality rate was 10.1％.The main cause of injury was traffic accident with an incidence of 48.3％.The diagnostic methods included electrocardiogram (ECG),enzymes and troponin I,echocardiography,and CT scanning,or confirmed by emergency thoracatomy.In the nonoperative group,patients were mainly myocardial contusion,with a mortality rate of 6.9％.In the operative group,patients were mainly cardiac rupture and pericardial hernia,and the mortality was 32.6％.The incidence of negative ECG between the two groups was not significantly different (16.7％ vs 11.6％,P＞0.05).The incidence of shock and mortality in the operative group were significantly higher than those in the the nonoperative group (P＜0.01).The number of death directly resulted from BCI in the operative group was greater than that in the nonoperative group (P＜0.05).Conclusions For BTI patients,BCI must be highly suspected,and necessary examinations should be given.To manage myocardial contusion without surgery,it is necessary to protect the heart,alleviate edema of myocardium,and control arrhythmia with drugs.To deal with those patients requiring operation,early recognition and expeditious thoracotomy are essential.

Characteristics of Psychiatric Patients Referred by Police to an Emergency Department / 신경정신의학

OBJECTIVES: This study compared the demographic and clinical characteristics of police referrals with referrals from other sources to a psychiatric emergency department. METHODS: A retrospective cross-sectional study was conducted on the data from the psychiatric emergency department of Ulsan University Hospital from January 2014 to October 2017. The study sample consisted of 79 psychiatric patients who were referred by police, and the characteristics of this group were compared with those of 240 psychiatric patients who were referred by other sources. The collected data were analyzed using a chi-square, Fisher's exact test, and independent sample t-tests. RESULTS: Among the 1768 psychiatric emergency visits, 89 (5.0%) were referred by police, and among the 79 referrals by police chosen as the study group, there were 4(5.1%) cases of emergent psychiatric admission. These patients referred by police were more likely to be male and in a lower socio-economic status. Police referrals were more likely to exhibit violent behavior, be restrained, and more likely to visit after working hours. They were notified more rapidly to the psychiatric department, less notified to other departments, and visited the psychiatric outpatient clinics less after discharge from the emergency department. CONCLUSION: The study results highlight the importance of understanding the characteristics of psychiatric emergency patients referred by police and identifying the problems of the current psychiatric emergency services. Systems need to be developed that clarify the roles of police in psychiatric emergencies and facilitate collaboration between police and mental health institutions.

Hafnia alvei: uma revisão sistemática de literatura / Hafnia alvei: a review systems of literature

A presença de Enterobacteriaceae indica a qualidade higiênica dos produtos alimentícios. Dentro do grupo das bactérias que fazem parte dessa família está Hafnia alvei. Estudo bibliométrico é uma importante ferramenta metodológica de revisão sistemática para reunir e sintetizar as diversas informações que surgem sobre um tema, inclusive sobre os estudos relativos a micro- -organismos. O objetivo deste trabalho foi realizar um estudo bibliométrico sobre este agente. Para tal foi utilizada a base de dados Web of Science usando o nome do agente e o termo food para a busca e limitando a pesquisa entre 2007 e 2017. As informações principais dos documentos foram registradas, bem como a característica principal das publicações sobre o tema. Foram encontrados 42 artigos científicos que contemplaram os termos de busca. A maioria das publicações ocorreu em países e períodos onde ocorreram surtos alimentares e há uma grande pesquisa relacionada à genoma e resistência a antimicrobianos. Avalia-se que ainda existem várias oportunidades de pesquisa sobre os micro-organismos, visto que eles são pouco estudados, principalmente em nosso país.

The presence of Enterobacteriaceae indicates the hygienic quality of food products. As a part of this family, there is an emergent pathogen: Hafnia alvei. Bibliometrics appears as an important tool to gather and synthesize all the information that appears about the new microorganisms. The objective of this paper is to perform a systematic review of literature with bibliometric analysis in order to know the evolution of these bacteria and seek opportunities for new research. To do this, the Web of Science database was searched, individually searching for Hafnia alvei refining for "food". The articles found were analyzed from the annual production, countries, institutions, areas of knowledge, authors who produced the most and periodicals most used. A total of 42 articles were selected for Hafnia alvei. Most publications have occurred in countries and periods where there have been food outbreaks and there is great genomerelated research and antimicrobial resistance. It is evaluated that there are still several research opportunities on microorganisms, since they are little studied, mainly in our country.

Prevalence of Guillain-Barré syndrome among Zika virus infected cases: a systematic review and meta-analysis

ABSTRACT Zika virus (ZIKV) is an emergent flavivirus transmitted mainly through Aedes spp. mosquitoes that is posing challenge to healthcare services in countries experiencing an outbreak. Usually ZIKV infection is mild, but in some cases it has been reported to progress into neurological diseases such as microcephaly in infants and Guillain-Barré syndrome (GBS) in adults. GBS is a debilitating autoimmune disorder that affects peripheral nerves. Since ZIKV caused massive outbreaks in South America in the past few years, we aimed to systematically review the literature and perform a meta-analysis to estimate the prevalence of GBS among ZIKV-infected individuals. We searched PubMed and Cochrane databases and selected three studies for a meta-analysis. We estimated the prevalence of ZIKV-associated GBS to be 1.23% (95% CI = 1.17-1.29%). Limitations include paucity of data regarding previous flavivirus infections and ZIKV-infection confirmation issues. Our estimate seems to be low, but cannot be ignored, since ZIKV outbreaks affects an overwhelming number of individuals and GBS is a life-threatening debilitating condition, especially in pregnant women. ZIKV infection cases must be closely followed to assure prompt care to reduce the impact of GBS associated-sequelae on the quality of life of those affected.
