Clinical observation of preemptive analgesia with pentazocine for perioperative pain management in partial splenectomy / 中国基层医药

Objective:To investigate the clinical effect of preemptive analgesia with pentazocine on perioperative pain management in partial splenectomy.Methods:A total of 100 patients with traumatic splenic rupture who underwent partial splenectomy at Yiwu Central Hospital between October 2019 and November 2021 were randomly assigned to either the control group or the study group, with 50 patients in each group using the random number table method. Both groups received patient-controlled analgesia postoperatively. Additionally, the study group received intravenous pentazocine administration before surgery. The amount of anesthetic used during surgery, postoperative anesthesia recovery indices, postoperative pain response, serum inflammatory factor levels, and the number of effective patient-controlled analgesia pump presses within 48 hours postoperatively were recorded and evaluated. Any adverse drug reactions were also monitored.Results:The dosages of propofol [(462.24 ± 27.13) mg] and remifentanil [(365.98 ± 26.78) μg] in the study group were significantly lower than those in the control group [(511.82 ± 26.32) mg, (406.86 ± 26.08) μg, t = 14.49, 12.63, both P < 0.001). The recovery time of spontaneous breathing [(6.86 ± 0.97) minutes], anesthesia recovery time [(13.24 ± 0.82) minutes] and extubation time [(17.14 ± 1.07) minutes] were significantly shorter than those in the control group [(7.62 ± 0.90) minutes, (14.32 ± 0.84) minutes, (18.22 ± 1.06) minutes, t = 5.80, 8.58, 6.93, all P < 0.001]. The Visual Analogue Scale (VAS) scores in the study group were significantly lower than those in the control group at 24 and 48 hours after surgery, both in resting and coughing state ( t = 7.82, 9.31, 4.95, 8.47, all P < 0.001). The serum levels of tumor necrosis factor-alpha, interleukin-1, and interleukin-6 were significantly lower in the study group than in the control group ( t = 21.53, 25.61, 18.45, 16.90, 17.33, 14.86, all P < 0.001), while the serum level of interleukin-10 was significantly higher in the study group than in the control group ( t = -20.85, -19.61, both P < 0.001). The number of effective patient-controlled pump analgesia presses within 48 hours postoperatively in the study group [(6.24 ± 1.17) times] was significantly lower than that in the control group [(10.26 ± 1.34) times, t = 12.95, P < 0.05). In addition, the overall incidence of adverse drug reactions in the study group [4.00% (2/50)] was significantly lower than that in the control group [18.00% (9/50), χ2 = 5.01, P < 0.05]. Conclusion:Preemptive analgesia with pentazocine for patients undergoing partial splenectomy can effectively reduce the dosage of anesthetics during surgery and the dosage of analgesics after surgery, enhance the recovery from postoperative anesthesia, suppress postoperative inflammatory reactions, alleviate pain responses, and minimize the risk of adverse drug reactions.

Are monocyte-to-HDL and C-reactive protein-to-albumin ratios useful for the diagnosis and follow-up of Takayasu arteritis?

SUMMARY OBJECTIVE: In this study, we aimed to investigate the role of erythrocyte sedimentation rate, C-reactive protein, neutrophil/lymphocyte ratio, platelet/lymphocyte ratio, monocyte/lymphocyte ratio, red blood cell distribution width, mean platelet volume, monocyte/HDL ratio, and C-reactive protein/albumin ratio in the diagnosis and treatment follow-up of active and remission Takayasu arteritis patients compared with healthy control group. METHODS: This is a retrospective case-control study in which 56 Takayasu arteritis patients and 40 age- and sex-matched healthy control were included. The blood values of Takayasu arteritis patients were analyzed during their active period and post-treatment remission periods, after comparing them with the healthy control. Furthermore, all parameters were evaluated by receiver operating characteristic analysis. RESULTS: Erythrocyte sedimentation rate, C-reactive protein, neutrophil/lymphocyte ratio, platelet/lymphocyte ratio, monocyte/lymphocyte ratio, monocyte/HDL ratio, and C-reactive protein/albumin ratio values were significantly higher in active Takayasu arteritis patients compared with healthy control and remission Takayasu arteritis groups. In the receiver operating characteristic analysis performed in active Takayasu arteritis and Takayasu arteritis patients in remission, C-reactive protein had the highest power to indicate disease activity, followed by C-reactive protein/albumin ratio, erythrocyte sedimentation rate, and monocyte/HDL ratio. When Takayasu arteritis in remission was compared with the healthy control, a significant difference was found between erythrocyte sedimentation rate, C-reactive protein, red blood cell distribution width, and C-reactive protein/albumin ratio, while no significant difference was found between monocyte/HDL ratio values. CONCLUSION: C-reactive protein/albumin ratio and red blood cell distribution width can be used in the diagnosis of Takayasu arteritis, and C-reactive protein/albumin ratio, red blood cell distribution width, and monocyte/HDL ratio measurements can be used in the follow-up. As C-reactive protein/albumin ratio is more powerful than C-reactive protein in differentiating the Takayasu arteritis group from the healthy control group, evaluation of C-reactive protein/albumin ratio together with albumin instead of evaluation of C-reactive protein alone when diagnosing the disease may help us to obtain more accurate results in daily practice.

Correlation between inflammatory mediators and biochemical markers in patients with active pulmonary tuberculosis / Correlação entre mediadores inflamatórios e marcadores bioquímicos em pacientes com tuberculose pulmonar ativa

Objective: Correlate inflammatory mediators and biochemical parameters in patients with active pulmonary tuberculosis (TB) treated at a public hospital in São Luís, MA. Methods: This is a case-control study of patients with a positive diagnosis of active pulmonary TB. Serum samples from patients and the control group were collected for the clinical trials, and epidemiological data were collected through medical records and interviews. The control group consisted of healthy volunteers with no previous contact with TB cases, matched by age and sex to the clinical group. To measure inflammatory cytokines, we used the Human IL-6 ELISA Set and Human IFN-γ ELISA Set kits. Oxidative stress was measured by quantification of thiobarbituric acid reactive substances (TBARS) and nitric oxide (NO). In biochemistry, the levels of uric acid, antistreptolysin "O" (AEO), alanine aminotransferase (ALT), amylase, aspartate aminotransferase (AST), calcium, total cholesterol, gamma-glutamyl transferase (Gamma GT), glucose, alkaline phosphatase, high-density lipoprotein (HDL), C-reactive protein (CRP) and triglycerides were measured. Results: The clinical group consisted of 53 patients. There was a substantial decrease in IFN-γ (p<0.0001) and a significant increase in IL-6 (p<0.0001).

Diagnostic value of systemic immune inflammation index in acute appendicitis

SUMMARY OBJECTIVE: Clinical diagnosis of acute appendicitis is often difficult and involves a synthesis of clinical, laboratory, and radiological findings. The aim of this study was to investigate whether the systemic immune inflammation index can be used as an effective parameter in the diagnosis of acute appendicitis and its reliability in the differentiation of complicated vs. non-complicated appendicitis. METHODS: The study was conducted retrospectively with patients admitted to the emergency department with abdominal pain and diagnosed with acute appendicitis. In total, 150 patients and 150 control cases were included in the study. Demographic data, medical history, white blood cell count, platelet count, neutrophil count, systemic immune inflammation index values, Alvarado score, adult appendicitis score, and pathology result of appendectomy material were retrieved from the hospital automation system and recorded in the data form. RESULTS: Neutrophil-lymphocyte ratio and systemic immune inflammation index were significantly higher, and platelet-neutrophil ratio and lymphocyte-neutrophil ratio were significantly lower in the patient group compared to the control group (p<0.001). Receiver operating characteristic analysis revealed that the sensitivity and specificity of systemic immune inflammation index with a cutoff value of 840.13 was 82 and 66.7%, respectively, for the diagnosis of acute appendicitis. Correlation analysis revealed that systemic immune inflammation index, Alvarado score, and adult appendicitis score were positively correlated, and this correlation was statistically significant. CONCLUSION: Systemic immune inflammation index may be used to promote the diagnosis of acute appendicitis and may reduce the need for radiation exposure and diagnostic imaging tests such as contrast-enhanced abdominal computed tomography. It can also be used to differentiate between complicated and non-complicated acute appendicitis cases.

Objective:To investigate the efficacy of montelukast sodium combined with methylprednisolone in the treatment of pediatric allergic purpura and its effects on inflammatory factors and immune function.Methods:A total of 94 children with allergic purpura who received treatment in Taizhou Women and Children's Hospital and Taizhou Hospital Medical Center (Group) Enze Hospital from March 2019 to March 2021 were included in this study. They were randomly divided into observation and control groups ( n = 47/group). The control group was treated with methylprednisolone. The observation group was treated with montelukast sodium combined with methylprednisolone. The course of treatment was 2 weeks in both groups. Efficacy and changes in inflammatory factors and immune function post-treatment relative to those pre-treatment were compared between the two groups. Results:Total response rate in the observation group [93.62% (44/47)] was significantly higher than that in the control group [74.47% (35/47), Z = 2.15, P < 0.05)]. After treatment, interleukin (IL-4), IL-6, and IL-18 levels in each group were significantly decreased compared with those before treatment ( tobservation group = 21.19, 22.26, 27.20, tcontrol group = 11.10, 13.21, 14.86, all P < 0.05). After treatment, IL-4, IL-6, and IL-8 levels in the observation group were (48.98 ± 5.21) ng/L, (34.10 ± 6.42) ng/L, and (53.29 ± 5.67) ng/L, respectively, which were significantly lower than (65.38 ± 7.08) ng/L, (47.83 ± 4.71) ng/L, (67.83 ± 7.10) ng/L in the control group ( t = 12.79, 11.82, 10.97, all P < 0.05). After treatment, CD3 +, CD4 +, and CD4 +/CD8 + in each group were significantly increased compared with those before treatment ( tobservation group = 14.27, 14.41, 17.61, tcontrol group = 6.90, 5.12, 7.40, all P < 0.05). After treatment, CD3 +, CD4 +, and CD4 +/CD8 + in the observation group were (68.94 ± 2.89)%, (39.94 ± 2.15)%, and (1.79 ± 0.13), respectively, which were significantly higher than (63.86 ± 3.28)%, (35.65 ± 2.31)%, and (1.53 ± 0.16) in the control group ( t = 7.96, 9.32, 8.64, all P < 0.05). After treatment, serum IgG and IgM levels in each group were significantly decreased compared with those before treatment ( tobservation group = 21.00, 7.99, tcontrol group = 8.38, 5.76, both P < 0.05). After treatment, serum IgG and IgM levels in the observation group were (1.43 ± 0.19) g/L and (9.74 ± 0.78) g/L, respectively, which were significantly lower than (1.95 ± 0.37) g/L and (10.89 ± 0.85) g/L in the control group ( t = 8.57, 6.83, both P < 0.05).

Correlation of probiotic consumption with serum inflammatory cytokines, endotoxin and post-stroke depression severity in patients with ischemic stroke / 国际脑血管病杂志

Objective:To investigate the correlation of probiotic consumption level with serum inflammatory cytokines, endotoxin and post-stroke depression (PSD) severity in patients with ischemic stroke.Methods:Patients with ischemic stroke visited the Department of Neurology, the Third Affiliated Hospital of Naval Medical University from May 2021 to June 2022 were prospectively included. At 6 months after discharge, the outpatient follow-up was conducted to investigate the consumption of probiotic products in the past six months, and depression was evaluated using the Self-rating Depression Scale (SDS). Multiple linear regression analysis was used to determine the correlation of consumption levels of probiotic products and serum inflammatory cytokines, endotoxin, and PSD severity.Results:A total of 168 patients with ischemic stroke were included, including 74 patients (44.0%) in the probiotic product high consumption group and 94 (56.0%) in the low consumption group. The incidence of PSD in the high consumption group was significantly lower than that in the low consumption group (22.97% vs. 38.30%; χ2=6.551, P=0.036). The serum pro-inflammatory cytokine interleukin-6 (IL-6) and endotoxin levels at the follow-up in the high consumption group were significantly lower than those in the low consumption group, while the anti-inflammatory cytokine IL-10 was significantly higher than that in the low consumption group (all P<0.05). Multiple linear regression analysis shows that the probiotic consumption level was significantly negatively correlated with the serum IL-6 ( β=-0.178, P=0.001) and endotoxin ( β=-0.107, P=0.035) at follow-up. PSD severity (SDS score) was negatively correlated with probiotic consumption level ( β=-0.309, P=0.001), and was positively correlated with IL-6 ( β=0.306, P=0.027) and endotoxin ( β=0.360, P=0.017) at follow-up. Conclusion:Probiotic products can reduce the severity of serum pro-inflammatory cytokines, endotoxin and PSD, and may be a non-drug treatment direction for PSD.

Clinical effects of stereotactic-guided endoscopic hematoma removal combined with early systematic rehabilitation training on hypertensive intracerebral hemorrhage in the basal ganglia / 中国基层医药

Objective:To investigate the clinical effects of stereotactic-guided endoscopic hematoma removal combined with early systematic rehabilitation training on hypertensive intracerebral hemorrhage in the basal ganglia.Methods:A total of 130 patients with hypertensive intracerebral hemorrhage in the basal nucleus who received treatment in Zhejiang Veteran Hospital from June 2019 to December 2021 were included in this randomized control study. They were randomly divided into a control group and a study group ( n = 65 per group). The control group received minimally invasive hematoma puncture. The study group received stereotactic-guided neuroendoscopic hematoma removal. After surgery, early systematic rehabilitation training was carried out, and surgical indicators were recorded. The levels of serum inflammatory factors and stress factors were determined. The recurrence, death, and complications as well as prognosis of cerebral hemorrhage were recorded in each group. Results:The operative time in the study group was (85.39 ± 5.24) minutes, which was significantly longer than (64.17 ± 4.31) minutes in the control group ( t = -14.56, P < 0.001). Hematoma clearance rate in the study group was (94.66 ± 5.18) %, which was significantly higher than (76.82 ± 5.39) % in the control group ( t = -17.63, P < 0.001). At 24 hours after surgery, tumor necrosis factor-α, interleukin-1, norepinephrine, and hydrocortisone levels in the study group were (68.29 ± 5.36) ng/L, (237.62 ± 13.87) ng/L, (75.39 ± 5.82) μg/L, and (30.96 ± 2.97) μg/L, respectively, which were significantly lower than (74.61 ± 5.62) ng/L, (295.47 ± 14.69) ng/L, (91.62 ± 6.41) μg/L, and (38.25 ± 3.16) μg/L in the control group ( t = 7.95, 18.42, 16.84, 11.75, all P < 0.001). There was no significant difference in the 6-month mortality rate between the two groups ( P > 0.05). The recurrence rate of cerebral hemorrhage and the overall incidence of complications in the study group were (1.54% (1/65) and (10.77% (7/65) in the study group, respectively, which were significantly lower than 12.31% (8/65) and 27.69% (18/65) in the control group ( χ2 = 4.30, 5.99, both P < 0.05). The overall excellent and good prognosis rate within 6 months in the study group was 86.15% (56/65), which was significantly higher than 67.69% (44/65) in the control group ( χ2 = 6.24, P < 0.05). Conclusion:Compared with minimally invasive hematoma puncture and drainage surgery, stereotactic-guided neuroendoscopic hematoma removal takes longer time, but it can better effectively increase hematoma removal rate and alleviate stress and inflammatory reactions in patients with hypertensive intracerebral hemorrhage in the basal ganglia. Early systematic rehabilitation training combined with stereotactic guided neuroendoscopic hematoma removal can help reduce the risk of recurrence and complications of cerebral hemorrhage and improve prognosis.

Naringenin attenuates cerebral ischemia/reperfusion injury by inhibiting oxidative stress and inflammatory response via the activation of SIRT1/FOXO1 signaling pathway in vitro

Purpose: To explore the protection of naringenin against oxygen-glucose deprivation/reperfusion (OGD/R)-induced HT22 cell injury, a cell model of cerebral ischemia/reperfusion (I/R) injury in vitro, focusing on SIRT1/FOXO1 signaling pathway. Methods: Cytotoxicity, apoptosis, reactive oxygen species (ROS) generation, malondialdehyde (MDA) content, 4-hydroxynonenoic acid (4-HNE) level, superoxide dismutase (SOD), glutathione peroxidase (GSH-Px) and catalase (CAT) activities were measured by commercial kits. Inflammatory cytokines levels were determined by enzyme-linked immunosorbent assay (ELISA). The protein expressions were monitored by Western blot analysis. Results: Naringenin significantly ameliorated OGD/Rinduced cytotoxicity and apoptosis in HT22 cells. Meanwhile, naringenin promoted SIRT1 and FOXO1 protein expressions in OGD/R-subjected HT22 cells. In addition, naringenin attenuated OGD/R-induced cytotoxicity, apoptosis, oxidative stress (the increased ROS, MDA and 4-HNE levels, and the decreased SOD, GSH-Px and CAT activities) and inflammatory response (the increased tumor necrosis factor-α, interleukin [IL]-1ß, and IL-6 levels and the decreased IL-10 level), which were blocked by the inhibition of the SIRT1/FOXO1 signaling pathway induced by SIRT1-siRNA transfection. Conclusion: Naringenin protected HT22 cells against OGD/R injury depending on its antioxidant and anti-inflammatory activities via promoting the SIRT1/FOXO1 signaling pathway.

A novel predictor in patients with coronary chronic total occlusion: systemic immune-inflammation index: a single-center cross-sectional study

SUMMARY OBJECTIVE: Severe inflammation is reportedly associated with subsequent cardiovascular events, including in patients with coronary artery disease. This study aimed to examine the prognostic value of systemic immune-inflammation index and determine mortality and clinical outcomes in patients with chronic coronary total occlusion. METHODS: Our study evaluated 366 consecutive coronary total occlusion patients. The clinical end points were all-cause mortality and major adverse cardiovascular events, which include target vessel revascularization, myocardial infarction, and cerebrovascular events during 105 months follow-up. RESULTS: The study findings showed 59 (16.1%) all-cause death, 22 (6%) target vessel revascularization cases, 32 (8.7%) myocardial infarction cases, and 13 (3.6%) cerebrovascular events cases, with a median follow-up of 49 months (26-74). Multivariate logistic regression analysis showed that systemic immune-inflammation index was not associated with target vessel revascularization, myocardial infarction, and cerebrovascular events. Multivariate Cox regression analysis found systemic immune-inflammation index to be associated with all-cause death. Kaplan-Meier analysis showed a lower survival rate and myocardial infarction-free survival time in patients with higher systemic immune-inflammation index scores. CONCLUSION: Although systemic immune-inflammation index is a preferable tool for the detection of mortality, it failed to give adverse outcomes. Larger multicenter studies are thus warranted to investigate the effect of systemic immune-inflammation index on clinical outcomes.

Objective:To investigate the predictive value of inflammatory markers for the risk of stroke-associated infection (SAI) in patients with anterior circulation large vessel occlusive stroke who received endovascular therapy.Methods:Patients with anterior circulation large vessel occlusive stroke received endovascular treatment in Nanjing First Hospital, Nanjing Medical University from 2016 to 2020 were retrospectively enrolled. The clinical data of SAI group and non-SAI group were compared. Multivariate logistic regression analysis was used to screen the independent influencing factors of SAI, and then the predictive nomogram was established according to these influencing factors to verify its clinical application efficiency. Results:A total of 409 patients were enrolled during the study. Their age was 71.3±11.7 years, and 250 were male (61.1%). The median baseline Naitonal Institutes of Health Stroke Scale (NIHSS) score was 16. One hundred and nineteen patients (29.1%) received intravenous thrombolysis, 376 (91.9%) were successfully recanalized after endovascular therapy, and 293 (71.6%) developed SAI. Univariate analysis showed that age, atrial fibrillation ratio, NIHSS score at admission, fasting blood glucose, triglyceride, high sensitivity C reactive protein (hs-CRP), leukocyte count, neutrophil count, neutrophil to lymphocyte ratio (NLR) and platelet to lymphocyte ratio (PLR) were significantly higher than those in the non-SAI group (all P<0.05). Multivariate logistic regression analysis showed that age, NIHSS score at admission, fasting blood glucose, hs-CRP, leukocyte count, neutrophil count and NLR were the independent influencing factors of SAI ( P<0.05). Receiver operating characteristics curve analysis showed that the predictive value of multiple inflammatory markers (hs-CRP, leukocyte count, neutrophil count and NLR) for SAI was significantly better than that of the single inflammatory marker ( P<0.01). The area under the curve was 0.782 (95% confidence interval 0.719-0.846), and the predictive sensitivity and specificity were 80.6% and 64.5% respectively. Decision curve analysis showed that compared with the traditional indicators, the predictive nomogram based on inflammation related indicators (hs-CRP, leukocyte count and NLR) had a higher net profitability for predicting SAI. Conclusion:The hs-CRP, leukocyte count and NLR can be used to predict the risks of SAI in patients with acute ischemic stroke receiving endovascular therapy.

The correlation analysis between plasma sclerostin levels and bone turnover markers and inflammation factors in hemodialysis patients / 中国医师进修杂志

Objective:To explore the correlation between plasma sclerostin (SOST) and bone turnover markers and inflammatory factors in hemodialysis patients.Methods:One hundred and eight patients admitted to Changsha Central Hospital Affiliated to Nanhua University from January 2018 to May 2019 were selected. The levels of plasma SOST at admission and at 3, 6 and 12 months of dialysis were determined by enzyme-linked immunosorbent assay. They were divided into low- SOSTgroup (56 cases) and high- SOSTgroup (52 cases) based on the mean value of SOST. The levels of serum bone turnover markers β-Ⅰ collagen carboxy-terminal peptide (β-CTX) and osteocalcin (OC), propeptide of type Ⅰ procollagen (PINP), full parathyroid hormone (iPTH), N-terminal osteocalcin (N-MID-OC), inflammatory factors interleukin-1β (IL-1β), interleukin-6 (IL-6), C-reactive protein (CRP), tumor necrosis factor-α (TNF-α) were compared between the two groups, abdominal aortic calcification (ACC) score was performed, and Pearson linear correlation analysis was used to analyze the relationship between SOST level of hemodialysis patients and bone turnover markers, inflammatory factors and ACC scores.Results:The baseline levels of β-CTX, OC, PINP, iPTH, and N-MID-OC in the low- SOST group were higher than those in the high- SOST group: (976.03 ± 205.27) ng/L vs. (781.34 ± 150.45) ng/L, (175.31 ± 50.49) ng/L vs. (125.75 ± 40.17) ng/L, (321.45 ± 82.14) μg/L vs. (259.41 ± 75.36) μg/L, (345.26 ± 102.65) ng/L vs. (198.52 ± 45.71) ng/L, (19.96 ± 5.01) μg/L vs. (17.41 ± 4.23) μg/L, the differences were statistically significant ( P<0.05). The baseline levels of IL-1β, IL-6, CRP, TNF-α and ACC scores in the low- SOST group were higher than those in the high- SOST group: (19.31 ± 6.01) ng/L vs. (15.23 ± 4.75) ng/L, (76.85 ± 20.34) ng/L vs. (57.98 ± 15.02) ng/L, (8.15 ± 2.36) mg/L vs. (7.23 ± 1.79) mg/L, (178.37 ± 55.52) ng/L vs. (157.42 ± 10.15) ng/L, (5.96 ± 1.78) scores vs. (5.11 ± 1.15) scores, the differences were statistically significant ( P<0.05). After treated for 3, 6 and 12 months, the levels of β-CTX, OC, PINP, iPTH, N-MIC-OC in hemodialysis patients were increased, the level of SOST was decreased, the levels of IL-1β, IL-6, CRP, TNF-α increased and ACC scores were increased, the differences were statistically significant ( P<0.05). The Pearson linear correlation analysis showed that SOST level and bone turnover markers β-CTX ( r = -0.465, P<0.001), OC( r = -0.498, P<0.001), PINP( r = -0.511, P<0.001), iPTH ( r = -0.396, P = 0.012), N-MID -OC ( r = -0.323, P = 0.031) and inflammatory factors IL-1β( r = -0.305, P = 0.046), IL-6( r = -0.318, P = 0.041), CRP( r = -0.327, P = 0.034) and TNF-α( r = -0.378, P = 0.024) in hemodialysis patients were negatively correlated, and negatively correlated with abdominal aortic calcification scores ( r = -0.301, P = 0.048). Conclusions:Plasma SOST level in hemodialysis patients is lower, which is negatively correlated with bone turnover markers, inflammatory factors, and calcification scores. Low SOST level can induce vascular calcification by mediating bone metabolism disorders and aggravating the body′s inflammatory response, and increase the risk of hemodialysis vascular calcification.

Association of inflammatory markers and thromboinflammatory factors before and after thrombolytic intervention with functional outcomes in elderly patients with acute cerebral infarction / 中华老年医学杂志

Objective:To explore the association of inflammatory markers and thromboinflammatory factors before and after thrombolytic intervention with functional outcomes in elderly patients with acute cerebral infarction.Methods:392 patients with acute cerebral infarction admitted to our hospital were randomly selected as study subjects and divided into an observation group(196 cases)treated with arterial thrombolytic therapy and a control group(196 cases)treated with intravenous thrombolysis.Functional outcomes of patients were assessed 72 hours after thrombolysis using the activities of daily living(ADL)scale and, based on the results, patients were divided into a poor functional outcome group and a good functional outcome group.Inflammatory markers such as neutrophil-to-lymphocyte ratio(NLR)and platelet-to-lymphocyte ratio(PLR)and thromboinflammatory factors such as monocyte chemoattractant protein-1(MCP-1), tissue plasminogen activator(t-PA), soluble CD40 ligand(sCD40L)and P-selectin before and after thrombolysis were measured.The relationship of these inflammatory markers and thromboinflammatory factors before thrombolysis with functional outcomes 72 hours after thrombolysis was analyzed.Results:NLR and PLR levels in the two groups after thrombolysis were significantly lower than those before thrombolysis(all P<0.05); Their levels in the observation group were lower than those in the control group(all P<0.05). After thrombolysis, MCP-1 levels in both groups were significantly higher and t-PA, sCD40L, P-selectin levels were significantly lower than pre-thrombolysis levels(all P<0.05); After thrombolysis, the observation group had better results than the control group(all P<0.05). Correlation analysis showed that NLR, PLR, MCP-1 and t-PA were positively correlated with NIHSS score( r=0.336, 0.264, 0.483, 0.549, all P<0.05). NLR, PLR, MCP-1, t-PA and sCD40L levels were significantly lower and P-selectin levels were significantly higher in the good functional outcome group than in the poor functional outcome group both before and 72 hours after thrombolysis( t=13.850, 18.208, 23.636, 22.371, 59.868, 96.646, 378.112, 141.213, 131.160, 110.039, 10.716, 11.108, P<0.05 for all). Logistic regression analysis showed that abnormal levels of NLR, PLR, MCP-1 and t-PA before and after thrombolysis were risk factors for adverse outcomes with thrombolytic intervention( P<0.05). ROC curves showed that the levels of NLR, PLR, MCP-1, t-PA, sCD40L and P-selectin before thrombolysis had a certain predictive value for the risk of adverse functional outcomes with thrombolysis. Conclusions:The levels of these inflammatory markers and thromboinflammatory factors before and after thrombolytic intervention have varying degrees of correlation with functional outcomes in elderly patients with acute cerebral infarction.

Características del SARS-CoV-2, COVID-19 y su diagnóstico en el laboratorio / Characteristics of SARS-CoV-2, COVID-19, and laboratory diagnosis

La enfermedad COVID­19 es causada por el virus SARS-CoV-2, descrito por primera vez en diciembre del 2019 en Wuhan, China, y declarada en marzo del 2020 como una pandemia mundial. Actualmente existen diversos métodos diagnósticos para COVID-19, siendo el estándar de oro la detección del material genético mediante la reacción en cadena de la polimerasa (PCR), en su variante, la RT-PCR, que detecta el material genético de tipo ARN presente en el virus. Sin embargo, es necesario disponer de pruebas rápidas con alta sensibilidad y precisión para realizarlas a gran escala y brindar un diagnóstico oportuno. Adicionalmente, se debe disponer de otras herramientas que, si bien no van a establecer un diagnóstico, le van a permitir al profesional brindar un mejor manejo clínico y epidemiológico que ayuden a predecir el agravamiento del paciente y su posible ingreso a UCI, destacando entre estas los niveles de dímero D, linfocitos, ferritina, urea y creatinina, entre otras. En esta revisión se evalúa la utilidad y limitaciones de los diferentes métodos diagnósticos para COVID-19, al igual que las características, fisiopatología y respuesta inmune al SARS-CoV-2, así como algunos aspectos preanalíticos de importancia que ayudan a minimizar errores en el diagnóstico como consecuencia de procedimientos incorrectos en la toma, transporte y conservación de la muestra, y que permiten al profesional emitir resultados veraces y confiables. Lo anterior se realizó basado en artículos originales, revisiones y guías clínicas

COVID­19 is caused by the SARS-CoV-2 virus, first described in December 2019 in Wuhan, China, and declared a global pandemic in March 2020. Currently there are various diagnostic methods for COVID-19, the gold standard is the detection of genetic material through polymerase chain reaction (PCR) in its variant, RT-PCR, which detects RNA-type genetic material present in the virus. However, it is necessary to have rapid tests with high sensitivity and precision to be performed on a large scale and provide timely diagnosis. Furthermore, other tools must be available, and although they will not establish the diagnosis, will allow the professional to provide better clinical and epidemiological management that will help predict the worsening of the patient and possible admission to the ICU. Among these, levels of D-dimer, lymphocytes, ferritin, urea and creatinine. In this review, the usefulness and limitations of the different diagnostic methods for COVID-19 are evaluated, as well as the characteristics, pathophysiology and immune response to SARS-CoV-2, and some important preanalytical aspects that allow minimizing diagnostic errors as a consequence of incorrect procedures in the collection, transport and conservation of the sample, that allow the professional to yield accurate and reliable results.
