METHODS: The data of 27 consecutive patients who underwent percutaneous transhepatic cholecystostomy for the management of acute cholecystitis from January 1999 to June 2003 was retrospectively evaluated. All of the patients had both clinical and sonographic signs of acute cholecystitis and had comorbid diseases. RESULTS: Ultrasound revealed gallbladder stones in 25 patients and acalculous cholecystitis in two patients. Cholecystostomy catheters were removed 14-32 d (mean 23 d) after the procedure in cases where complete regression of all symptoms was achieved. There were statistically significant reductions in leukocytosis, (13.7 × 103 ± 1.3 × 103 μg/L vs 13 × 103 ± 1 × 103 μg/L, P < 0.05 for 24 h after PC; 13.7 × 103 ± 1.3 × 103 μg/L vs 8.3 × 103 ± 1.2 × 103 μg/L, P < 0.0001 for 72 h after PC), C -reactive protein (51.2 ± 18.5 mg/L vs 27.3 ± 10.4 mg/L, P < 0.05 for 24 h after PC; 51.2 ± 18.5 mg/L vs 5.4 ± 1.5 mg/L, P < 0.0001 for 72 h after PC), and fever (38 ± 0.35℃ vs 37.3 ± 0.32℃, P < 0.05 for 24 h after PC; 38 ± 0.35℃ vs 36.9 ± 0.15℃, P < 0.0001 for 72 h after PC). Sphincterotomy and stone extraction was performed successfully with endoscopic retrograde cholangio-pancreatography (ERCP) in three patients. After cholecystostomy, 5 (18%) patients underwent delayed cholecystectomy without any complications. Three out of 22 patients were admitted with recurrent acute cholecystitis during the follow-up and recoveredwith medical treatment. Catheter dislodgement occurred in three patients spontaneously, and two of them were managed by reinsertion of the catheter. CONCLUSION: As an alternative to surgery, percutan- eous cholecystostomy seems to be a safe method in critically ill patients with acute cholecystitis and can be performed with low mortality and morbidity.

The aim of this study was to describe the therapeutic profile and outcome of patients suffering from upper digestive haemorrhage. Methodology: This was a prospective study carried out in the internal medicine department of the Sikasso Regional Hospital from August 2022 to July 2023. All adult patients presenting with upper digestive haemorrhage and having given their consent, were included. Data were analyzed using SPSS version 21 software. Results: Sixty-three patients were enrolled. The mean age was 49.7 ± 18.99 years, with a male-female sex ratio of 2.2. Ruptured esophageal varices (37.5%) and peptic ulcer (25%) were the main etiologies. Pharmacological treatment was dominated by proton pump inhibitors (85.7%). Hemostasis endoscopy accounted for 3.17%. The evolution was marked by hemorrhagic arrest (69.84%), recurrence of hemorrhage (11.11%) and death (19.04%), the main cause of which was hemorrhagic shock (58.3%). We found no statistically significant relationship between prognosis and etiologies (P = 0.11), and length of hospital stay (P = 0.18). Conclusion: Hemostasis endoscopy remains a challenge for Sikasso Hospital. A holistic strategy of communication and community awareness-raising, combined with adequate technical facilities, will help to improve patient care and outcomes.展开更多

Understanding the embryological processes of the intestinal tract assists in the interpretation of abnormal sonographic findings. In general terms, the examination principally comprises interrogation of the colon, mesentery and small intestine using both lowfrequency and high-frequency probes. Interpretation of findings on GIUS includes assessment of bowel wall thickness, symmetry of this thickness, evidence of transmural changes, assessment of vascularity using Doppler imaging and assessment of other specific features including lymph nodes, mesentery and luminal motility. In addition to B-mode imaging, transperineal ultrasonography, elastography and contrast-enhanced ultrasonography are useful adjuncts. This supplement expands upon these features in more depth.展开更多

Given this observation, what are the population’s attitudes towards LLINs that could explain the high endemicity of malaria in Dimbokro? The aim of this study is to assess the knowledge, attitudes and practices of people in the health area of Nofou, one of the villages in the Dimbokro health district where malaria is most prevalent, with a view to strengthening malaria control strategies. A collection of historical health data (malaria cases and LLIN usage rates) and a cross-sectional questionnaire survey was carried out from July 20 to August 03, 2022 in 400 households selected by systematic random sampling. Data were entered using Epi Info 7 and multivariate statistical analyses were performed using IBM SPSS 22 software. In the Dimbokro health district, the rate of LLIN use was negatively correlated (r = -0.771) with malaria incidence over the six years of historical data collection. Households had an average of 53% good knowledge, 68.6% good practices and 28.4% good attitudes towards LLINs. The study also revealed that the main factors explaining LLIN use in the Nofou health area are mosquito bite (ORa = 5.29 (1.12 - 25.04)), age of household members (ORa = 1.07 (1.01 - 1.14)) and marital status (ORa = 8.45 (1.70 - 45.02)). Awareness-raising on the use of LLINs should be intensified in the Dimbokro health district. Other control strategies, such as vector control and environmental sanitation, should be considered to combat malaria.展开更多

The aim of this study was to investigate morbidity and factors associated with mortality in children aged 1 month to 15 years. Methodology: This was a cross-sectional study which took place from January 1 to December 31, 2020 covering children aged 1 month to 15 years hospitalized at the Kalaban-Coro CSRéf. Data were entered into Excel and analyzed using SPSS version 20 software. Results: Five hundred children aged 1 months to 15 years were included. The age range 1 to 5 years (53.6%) and male sex (58.2%) were the most represented. Malaria (72.2%), acute respiratory infections (6.2%) and diarrhea/dehydration (3%) were the main morbidities. Mortality was estimated at 10.6%, and the two main causes of death were malaria (56.6%) and acute respiratory infections (7.54%). Univariate analysis revealed a statistically significant association between the dependent variable (death) and age (p Conclusion: This study confirms the high rate of infant and child morbidity and mortality in our health facilities. Strengthening human resources and intensifying behavior-change communication can help reverse the trend.展开更多

However, transport networks are influenced by meteorological hazards, such as rainstorms,hurricanes, and fog. Adverse weather impacts can easily spread over a network. Existing models evaluating such impacts usually neglect the transdisciplinary nature of approaches for dealing with this problem. In this article, a mesoscopic mathematical model is proposed to quantitatively assess the adverse impact of rainstorms on a regional transport network in northern China by measuring the reduction in traffic volume. The model considers four factors: direct and secondary impacts of rainstorms, interdependency between network components, and recovery abilities of cities. We selected the Beijing-Tianjin-Hebei region as the case study area to verify our model.Socioeconomic, precipitation, and traffic volume data in this area were used for model calibration and validation.The case study highlights the potential of the proposed model for rapid disaster loss assessment and risk reduction planning.展开更多

Methodology: This was a prospective observational study of the descriptive type over a period of 12 months from January 01 to December 31, 2020 in the surgical emergency room at the CHU Ignace Deen. Included in the study were all patients admitted for peritonitis aged greater than or equal to 18 years. The parameters were epidemiological, clinical and anesthetic. Results: Of the 653 admissions to surgical emergencies in 2020, 185 cases presented with peritonitis, i.e. 29.3%. The average age was 38.6 ± 16.64 years with extremes of 18 and 90 years. The sex ratio was 1.89. The comorbidities were dominated by gastritis and hypertension, i.e. 22%. The patients were classified as ASA 3U (52.4%), ASA2 U (39.5%) and ASA 4 U (8.1%). Preoperative resuscitation was provided only with 100% saline. 25.5% of patients had received a blood transfusion. The response time was less than 48 hours, i.e. 77.6%. General anesthesia was performed for all patients. Ketamine was the most used IV hypnotic (56.3%) combined with 100% halothane. The curares used were suxamethonium at (81.6%), Atracurium (81.6%) and rocuronium at (18.3%). Fentanyl was the only morphine used. Senior anesthesia technicians provided anesthesia in (63.2%). Intraoperative incidents were dominated by hypotension, difficult intubation, cardiac arrest, respectively 10.3%, 8% and 0.5%. The immediate postoperative incidents were arterial hypotension, nausea and desaturation, respectively 52.9%, 80% and 32.4%. Mortality was 3.4%. Conclusion: The perioperative management of peritonitis in the emergency room must be as early as possible in order to reduce morbidity and mortality.展开更多

Patients and Methods: Observational descriptive and analytical study with prospective collection of data over a period of one year from January 1 to December 31, 2021. Patients aged 65 or over were included. Abstract: During the study period, 223 cases were collected out of 587 patients admitted, giving a prevalence of 37.9%. The average age was 74.127.39 ± years with extremes of 65 and 96 years and a male predominance (58.7%). The comorbidities were dominated by arterial hypertension (71.3%). The patients were: transferred from medical and surgical emergencies (75.8%). The average admission time was 48.8 ± 29.8 hours. One hundred and eight patients had a Glasgow score between 3 and 7. The reasons for admission were dominated by vascular causes (51.6%). Strokes of any type accounted for 43.9% of these reasons for admission. The average time for carrying out the biological assessments and imaging was 41.8 ± 27.3 hours with the extremes of 3 and 89 hours, 37.2% had a complete assessment within 24 hours. The average duration of hospitalization was 7.10 ± 8.87 days with extremes of 1 and 72 days. The mortality rate was 71.7%. Conclusion: This study has made it possible to take stock of the reasons for the admission of elderly subjects to intensive care. It appears that vascular causes are the main reasons for admission with heavy comorbidities which results in high mortality.展开更多

This disease is also an important public health problem. Clinical manifestations can be classified as cutaneous, mucocutaneous, and visceral leishmaniasis, depending on the species of parasite and the host’s immune status. Although the cutaneous form is not fatal, it often causes disfiguring scars on the skin[1].展开更多
文摘AIM: To assess the efficacy and safety of ultrasound guided percutaneous cholecystostomy (PC) in the treatment of acute cholecystitis in a well-defined high risk patients under general anesthesia. METHODS: The data of 27 consecutive patients who underwent percutaneous transhepatic cholecystostomy for the management of acute cholecystitis from January 1999 to June 2003 was retrospectively evaluated. All of the patients had both clinical and sonographic signs of acute cholecystitis and had comorbid diseases. RESULTS: Ultrasound revealed gallbladder stones in 25 patients and acalculous cholecystitis in two patients. Cholecystostomy catheters were removed 14-32 d (mean 23 d) after the procedure in cases where complete regression of all symptoms was achieved. There were statistically significant reductions in leukocytosis, (13.7 × 103 ± 1.3 × 103 μg/L vs 13 × 103 ± 1 × 103 μg/L, P < 0.05 for 24 h after PC; 13.7 × 103 ± 1.3 × 103 μg/L vs 8.3 × 103 ± 1.2 × 103 μg/L, P < 0.0001 for 72 h after PC), C -reactive protein (51.2 ± 18.5 mg/L vs 27.3 ± 10.4 mg/L, P < 0.05 for 24 h after PC; 51.2 ± 18.5 mg/L vs 5.4 ± 1.5 mg/L, P < 0.0001 for 72 h after PC), and fever (38 ± 0.35℃ vs 37.3 ± 0.32℃, P < 0.05 for 24 h after PC; 38 ± 0.35℃ vs 36.9 ± 0.15℃, P < 0.0001 for 72 h after PC). Sphincterotomy and stone extraction was performed successfully with endoscopic retrograde cholangio-pancreatography (ERCP) in three patients. After cholecystostomy, 5 (18%) patients underwent delayed cholecystectomy without any complications. Three out of 22 patients were admitted with recurrent acute cholecystitis during the follow-up and recoveredwith medical treatment. Catheter dislodgement occurred in three patients spontaneously, and two of them were managed by reinsertion of the catheter.

文摘Background:Systematic evaluation of the successful heartbeat recovery rate(HRR)in patients during the platinum ten minutes after cardiac arrest.Methods:The databases of CNKI(January 1979–March 2019),Chongqing VIP(January 1989–March 2019),Wanfang(January 1990–March 2019)and Web of Science(January 1900-May 2020)were searched.To collect the clinical data of patients with cardiac arrest before hospitalization and analyze the cardiopulmonary resuscitation(CPR)at different times.Literature selection and data extraction were carried out by two researchers independently,and the meta package of R software(version 3.61)was used for analysis.Results:A total of 116 papers met the inclusion criteria,including 37,181 patients.Of these patients,3367 had their heartbeats successfully restored.The results showed a high degree of heterogeneity(χ2=6999.21,P<0.01,I2=97.6%).The meta-analysis was conducted using a random-effects model.The combined effect size was 0.199(0.157–0.250).(1)According to the five CPR groups(International Cardiopulmonary Resuscitation Guide 2000,2005,2010,2015 and other versions),the HRR of other versions[0.264(0.176–0.375)]was higher than the International Cardiopulmonary Resuscitation 2005 edition[0.121(0.092–0.158)].(2)The rescue time was divided into the 0 to≤5 min group,the 5 to≤10 min group,the 10 to≤15 min group,and the>15 min group.The HRR were 0.417(0.341–0.496),0.143(0.104–0.193),0.049(0.034–0.069),and 0.022(0.009–0.051),respectively.The HRR was higher in the 0 to≤5 min group than in the 5 to≤10 min group,the 10 to≤15 min group and the>15 min group.There was no difference between the 10 to≤15 min group and the>15 min group.(3)When the groups were stratified with the cutoff of 10 min,the≤10 min group HRR[0.250(0.202–0.306)]was higher than the>10 min group rate[0.041(0.029–0.057)].(4)The HRR of the telephone guidance group was[0.273(0.227–0.325)]lower than that of the 0 to≤5 min group[0.429(0.347–0.516)]but higher than that of the 5 to≤10 min group,the
文摘脓毒症是一种由感染引起的异质性疾病,感染触发了一系列复杂的局部或者全身的免疫炎症反应,引起多器官功能衰竭,发病率和病死率显著升高。由于至今仍然没有诊断脓毒症的金标准,所以脓毒症的临床诊断仍是一个难题。因此,脓毒症的临床诊断需要不断改变来满足临床和研究的要求。然而,尽管有许多新型的生物标记和筛选工具去预测脓毒症发生的风险,但是这些措施的诊断价值和有效性不足以让人满意,并且没有充分的证据去建议临床使用这些新技术。因此,脓毒症的临床诊断标准需要定期更新去适应不断产生的新证据。这篇综述旨在呈现当前脓毒症的诊断和早期识别方面的最新研究证据。临床运用不同的诊断方法的推荐意见依赖于推荐、评价、发展和评估分级体系(Grades of Recommendation Assessment,Development and Evaluation,GRADE),因为大部分的研究是观察性研究,并没有对这些方法进行可靠评估,采用的是两步推理方法。未来需要更多研究来确认或者反驳某一特殊的指标检测,同时应该直接采用相关病人的结果数据。

文摘The COVID-19 pandemic has emerged as a global health emergency due to its association with severe pneumonia and relative high mortality.However,the molecular characteristics and pathological features underlying COVID-19 pneumonia remain largely unknown.To characterize molecular mechanisms underlying COVID-19 pathogenesis in the lung tissue using a proteomic approach,fresh lung tissues were obtained from newly deceased patients with COVID-19 pneumonia.After virus inactivation,a quantitative proteomic approach combined with bioinformatics analysis was used to detect proteomic changes in the SARS-CoV-2-infected lung tissues.We identified significant differentially expressed proteins involved in a variety of fundamental biological processes including cellular metabolism,blood coagulation,immune response,angiogenesis,and cell microenvironment regulation.Several inflammatory factors were upregulated,which was possibly caused by the activation of NF-κB signaling.Extensive dysregulation of the lung proteome in response to SARS-CoV-2 infection was discovered.Our results systematically outlined the molecular pathological features in terms of the lung response to SARS-CoV-2 infection,and provided the scientific basis for the therapeutic target that is urgently needed to control the COVID-19 pandemic.
文摘Introduction: Upper digestive hemorrhage is one of the main digestive emergencies and remains a major cause of morbidity and mortality in Mali. The aim of this study was to describe the therapeutic profile and outcome of patients suffering from upper digestive haemorrhage. Methodology: This was a prospective study carried out in the internal medicine department of the Sikasso Regional Hospital from August 2022 to July 2023. All adult patients presenting with upper digestive haemorrhage and having given their consent, were included. Data were analyzed using SPSS version 21 software. Results: Sixty-three patients were enrolled. The mean age was 49.7 ± 18.99 years, with a male-female sex ratio of 2.2. Ruptured esophageal varices (37.5%) and peptic ulcer (25%) were the main etiologies. Pharmacological treatment was dominated by proton pump inhibitors (85.7%). Hemostasis endoscopy accounted for 3.17%. The evolution was marked by hemorrhagic arrest (69.84%), recurrence of hemorrhage (11.11%) and death (19.04%), the main cause of which was hemorrhagic shock (58.3%). We found no statistically significant relationship between prognosis and etiologies (P = 0.11), and length of hospital stay (P = 0.18). Conclusion: Hemostasis endoscopy remains a challenge for Sikasso Hospital. A holistic strategy of communication and community awareness-raising, combined with adequate technical facilities, will help to improve patient care and outcomes.
文摘BACKGROUND:There are several reasons why resuscitation measures may lead to inferior results:difficulties in team building,delayed realization of the emergency and interruption of chest compression.This study investigated the outcome of a new form of in-hospital cardiopulmonary resuscitation(CPR) training with special focus on changes in self-assurance of potential helpers when faced with emergency situations.METHODS:Following a 12-month period of CPR training,questionnaires were distributed to participants and non-participants.Those non-participants who intended to undergo the training at a later date served as control group.RESULTS:The study showed that participants experienced a significant improvement in selfassurance,compared with their remembered self-assurance before the training.Their self-assurance also was significantly greater than that of the control group of non-participants.CONCLUSION:Short lessons in CPR have an impact on the self-assurance of medical and non-medical personnel.
文摘Gastrointestinal ultrasound is a practical, safe, cheap and reproducible diagnostic tool in inflammatorybowel disease gaining global prominence amongst clinicians. Understanding the embryological processes of the intestinal tract assists in the interpretation of abnormal sonographic findings. In general terms, the examination principally comprises interrogation of the colon, mesentery and small intestine using both lowfrequency and high-frequency probes. Interpretation of findings on GIUS includes assessment of bowel wall thickness, symmetry of this thickness, evidence of transmural changes, assessment of vascularity using Doppler imaging and assessment of other specific features including lymph nodes, mesentery and luminal motility. In addition to B-mode imaging, transperineal ultrasonography, elastography and contrast-enhanced ultrasonography are useful adjuncts. This supplement expands upon these features in more depth.
文摘The Dimbokro health district has one of the highest incidences of malaria in Côte d’Ivoire, despite numerous campaigns to distribute Long-Acting Impregnated Mosquito Nets (LLINs). Given this observation, what are the population’s attitudes towards LLINs that could explain the high endemicity of malaria in Dimbokro? The aim of this study is to assess the knowledge, attitudes and practices of people in the health area of Nofou, one of the villages in the Dimbokro health district where malaria is most prevalent, with a view to strengthening malaria control strategies. A collection of historical health data (malaria cases and LLIN usage rates) and a cross-sectional questionnaire survey was carried out from July 20 to August 03, 2022 in 400 households selected by systematic random sampling. Data were entered using Epi Info 7 and multivariate statistical analyses were performed using IBM SPSS 22 software. In the Dimbokro health district, the rate of LLIN use was negatively correlated (r = -0.771) with malaria incidence over the six years of historical data collection. Households had an average of 53% good knowledge, 68.6% good practices and 28.4% good attitudes towards LLINs. The study also revealed that the main factors explaining LLIN use in the Nofou health area are mosquito bite (ORa = 5.29 (1.12 - 25.04)), age of household members (ORa = 1.07 (1.01 - 1.14)) and marital status (ORa = 8.45 (1.70 - 45.02)). Awareness-raising on the use of LLINs should be intensified in the Dimbokro health district. Other control strategies, such as vector control and environmental sanitation, should be considered to combat malaria.
文摘Introduction: Infant and child mortality is a worldwide concern, but developing countries such as Mali are more affected. The aim of this study was to investigate morbidity and factors associated with mortality in children aged 1 month to 15 years. Methodology: This was a cross-sectional study which took place from January 1 to December 31, 2020 covering children aged 1 month to 15 years hospitalized at the Kalaban-Coro CSRéf. Data were entered into Excel and analyzed using SPSS version 20 software. Results: Five hundred children aged 1 months to 15 years were included. The age range 1 to 5 years (53.6%) and male sex (58.2%) were the most represented. Malaria (72.2%), acute respiratory infections (6.2%) and diarrhea/dehydration (3%) were the main morbidities. Mortality was estimated at 10.6%, and the two main causes of death were malaria (56.6%) and acute respiratory infections (7.54%). Univariate analysis revealed a statistically significant association between the dependent variable (death) and age (p Conclusion: This study confirms the high rate of infant and child morbidity and mortality in our health facilities. Strengthening human resources and intensifying behavior-change communication can help reverse the trend.

文摘Grassland fire is one of the most important disturbance factors in the natural ecosystems.This paper focuses on the spatial distribution of long-term grassland fire patterns in the Hulun Buir Grassland located in the northeast of Inner Mongolia Autonomous Region in China.The density or ratio of ignition can reflect the relationship between grassland fire and different ignition factors.Based on the relationship between the density or ratio of ignition in different range of each ignition factor and grassland fire events,an ignition probability model was developed by using binary logistic regression function and its overall accuracy averaged up to 81.7%.Meanwhile it was found that daily relative humidity,daily temperature,elevation,vegetation type,distance to county-level road,distance to town are more important determinants of spatial distribution of fire ignitions.Using Monte Carlo method,we developed a time-dependent stochastic ignition probability model based on the distribution of inter-annual daily relative humidity and daily temperature.Through this model,it is possible to estimate the spatial patterns of ignition probability for grassland fire,which will be helpful to the quantitative evaluation of grassland fire risk and its management in the future.

文摘Cities are centers of socioeconomic activities,and transport networks carry cargoes and passengers from one city to another. However, transport networks are influenced by meteorological hazards, such as rainstorms,hurricanes, and fog. Adverse weather impacts can easily spread over a network. Existing models evaluating such impacts usually neglect the transdisciplinary nature of approaches for dealing with this problem. In this article, a mesoscopic mathematical model is proposed to quantitatively assess the adverse impact of rainstorms on a regional transport network in northern China by measuring the reduction in traffic volume. The model considers four factors: direct and secondary impacts of rainstorms, interdependency between network components, and recovery abilities of cities. We selected the Beijing-Tianjin-Hebei region as the case study area to verify our model.Socioeconomic, precipitation, and traffic volume data in this area were used for model calibration and validation.The case study highlights the potential of the proposed model for rapid disaster loss assessment and risk reduction planning.

文摘Background：Metabolic syndrome （MS） is a risk factor for stroke and thromboembolism event.Left atrial or LA appendage （LA/LAA） thrombus is a surrogate of potential stroke.The relationship between MS and atrial thrombus remains unclear.In this study,we sought to investigate the effect of MS on risk stratification of LA/LAA thrombus formation in patients with nonvalvular atrial fibrillation （NVAF）.Methods：This cross-sectional study enrolled 294 consecutive NVAF patients without prior anticoagulant and lipid-lowering therapies.LA/LAA thrombus was determined by transesophageal echocardiography.Risk assessment of LA/LAA thrombus was performed using the CHADS2,CHA2DS2-VASc,MS,CHADS2-MS,and CHA2DS2-VASc-MS scores.Logistic regression analyses were performed to determine which factors were significantly related to LA/LAA thrombus.Odds ratio （OR） including 95% confidence interval was also calculated.The predictive powers of different scores for the risk of LA/LAA thrombus were represented by C-statistics and compared by receiver operating characteristic （ROC） analysis.Results：LA/LAA thrombi were identified in 56 patients （19.0%）.Logistic analysis showed that MS was the strongest risk factor for LA/LAA thrombus in NVAF patients （OR =14.698,P 〈 0.001）.ROC curve analyses revealed that the C-statistics of CHADS2-MS and CHA2DS2-VASc-MS was significantly higher than those of CHADS2 and CHA2DS2-VASc scores （CHADS2-MS vs.CHADS2,0.807 vs.0.726,P=0.0019）.Furthermore,MS was helpful for identifying individuals with a high risk of LA/LAA thrombus in the population with a low risk of stroke （CHADS2 or CHA2DS2-VASc score =0）.Conclusions：MS is associated with LA/LAA thrombus risk in patients with NVAF.In addition to the CHADS2 and CHA2DS2-VASc scores,the CHADS2-MS and CHA2DS2-VASc-MS scores provide additional information on stroke risk assessment.
文摘Background:Cardiopulmonary resuscitation(CPR)strategies in COVID-19 patients differ from those in patients suffering from cardiogenic cardiac arrest.During CPR,both healthcare and non-healthcare workers who provide resuscitation are at risk of infection.The Working Group for Expert Consensus on Prevention and Cardiopulmonary Resuscitation for Cardiac Arrest in COVID-19 has developed this Chinese Expert Consensus to guide clinical practice of CPR in COVID-19 patients.Main recommendations:1)A medical team should be assigned to evaluate severe and critical COVID-19 for early monitoring of cardiac-arrest warning signs.2)Psychological counseling and treatment are highly recommended,since sympathetic and vagal abnormalities induced by psychological stress from the COVID-19 pandemic can induce cardiac arrest.3)Healthcare workers should wear personal protective equipment(PPE).4)Mouth-to-mouth ventilation should be avoided on patients suspected of having or diagnosed with COVID-19.5)Hands-only chest compression and mechanical chest compression are recommended.6)Tracheal-intubation procedures should be optimized and tracheal-intubation strategies should be implemented early.7)CPR should be provided for 20-30 min.8)Various factors should be taken into consideration such as the interests of patients and family members,ethics,transmission risks,and laws and regulations governing infectious disease control.Changes in management:The following changes or modifications to CPR strategy in COVID-19 patients are proposed:1)Healthcare workers should wear PPE.2)Hands-only chest compression and mechanical chest compression can be implemented to reduce or avoid the spread of viruses by aerosols.3)Both the benefits to patients and the risk of infection should be considered.4)Hhealthcare workers should be fully aware of and trained in CPR strategies and procedures specifically for patients with COVID-19.
文摘Objective: Describe the perioperative management of peritonitis in surgical emergencies. Methodology: This was a prospective observational study of the descriptive type over a period of 12 months from January 01 to December 31, 2020 in the surgical emergency room at the CHU Ignace Deen. Included in the study were all patients admitted for peritonitis aged greater than or equal to 18 years. The parameters were epidemiological, clinical and anesthetic. Results: Of the 653 admissions to surgical emergencies in 2020, 185 cases presented with peritonitis, i.e. 29.3%. The average age was 38.6 ± 16.64 years with extremes of 18 and 90 years. The sex ratio was 1.89. The comorbidities were dominated by gastritis and hypertension, i.e. 22%. The patients were classified as ASA 3U (52.4%), ASA2 U (39.5%) and ASA 4 U (8.1%). Preoperative resuscitation was provided only with 100% saline. 25.5% of patients had received a blood transfusion. The response time was less than 48 hours, i.e. 77.6%. General anesthesia was performed for all patients. Ketamine was the most used IV hypnotic (56.3%) combined with 100% halothane. The curares used were suxamethonium at (81.6%), Atracurium (81.6%) and rocuronium at (18.3%). Fentanyl was the only morphine used. Senior anesthesia technicians provided anesthesia in (63.2%). Intraoperative incidents were dominated by hypotension, difficult intubation, cardiac arrest, respectively 10.3%, 8% and 0.5%. The immediate postoperative incidents were arterial hypotension, nausea and desaturation, respectively 52.9%, 80% and 32.4%. Mortality was 3.4%. Conclusion: The perioperative management of peritonitis in the emergency room must be as early as possible in order to reduce morbidity and mortality.
文摘Objective: To determine the reasons for admission of elderly subjects and the prognosis in general intensive care. Patients and Methods: Observational descriptive and analytical study with prospective collection of data over a period of one year from January 1 to December 31, 2021. Patients aged 65 or over were included. Abstract: During the study period, 223 cases were collected out of 587 patients admitted, giving a prevalence of 37.9%. The average age was 74.127.39 ± years with extremes of 65 and 96 years and a male predominance (58.7%). The comorbidities were dominated by arterial hypertension (71.3%). The patients were: transferred from medical and surgical emergencies (75.8%). The average admission time was 48.8 ± 29.8 hours. One hundred and eight patients had a Glasgow score between 3 and 7. The reasons for admission were dominated by vascular causes (51.6%). Strokes of any type accounted for 43.9% of these reasons for admission. The average time for carrying out the biological assessments and imaging was 41.8 ± 27.3 hours with the extremes of 3 and 89 hours, 37.2% had a complete assessment within 24 hours. The average duration of hospitalization was 7.10 ± 8.87 days with extremes of 1 and 72 days. The mortality rate was 71.7%. Conclusion: This study has made it possible to take stock of the reasons for the admission of elderly subjects to intensive care. It appears that vascular causes are the main reasons for admission with heavy comorbidities which results in high mortality.

文摘Most commercially available herbicides contain surfactants as co-formulants to increase adhesion and absorption by plant leaves.Ethoxylated amines,one of the most used surfactants,are non-ionic and derived from animal fats.They represent a class of surfactants with similar structural features,including polyethoxylated tallow amine(POEA).POEA is widely used in glyphosate,glufosinate-containing herbicides.In 2015,the European Food Safety Society(EFSA)concluded that POEA was more toxic than glyphosate when tested in glyphosate-based formulations.[1]They also attributed the poisoning following ingestion by humans to the presence of POEA.
文摘Leishmaniasis is a serious parasitic disease caused by Leishmania species transmitted by the bite of sandflies. This disease is also an important public health problem. Clinical manifestations can be classified as cutaneous, mucocutaneous, and visceral leishmaniasis, depending on the species of parasite and the host’s immune status. Although the cutaneous form is not fatal, it often causes disfiguring scars on the skin[1].
