Introducción. El melanoma es la proliferación maligna de melanocitos asociado a un comportamiento agresivo. El objetivo de este estudio fue determinar las variables histológicas del melanoma cutáneo. Métodos. Estudio observacional retrospectivo, transversal descriptivo, realizado con reportes de patologías de pacientes con diagnóstico de melanoma cutáneo en un laboratorio de patología en Cali, Colombia, entre 2016-2021. Se incluyeron las variables edad, sexo, localización, subtipo, espesor de Breslow, ulceración, márgenes, mitosis, invasión linfovascular, neurotrofismo, regresión tumoral, nivel de Clark e infiltración tumoral por linfocitos. Resultados. Se obtuvieron 106 reportes y fueron excluidos 54 por duplicación. Se incluyeron 52 registros, la media de edad fue de 61 años, con una mayor frecuencia de mujeres (55,8 %). De los 33 casos donde se especificó el subtipo histológico, el más frecuente fue el de extensión superficial (66,6 %), seguido del acral lentiginoso (18,1 %) y nodular con (15,2 %). La localización más frecuente fue en extremidades (61,5 %). El espesor de Breslow más común fue IV (34,6 %) y el nivel de Clark más frecuente fue IV (34,6 %). La ulceración estuvo en el 40,4 %. El subtipo nodular fue el de presentación más agresiva, donde el 100 % presentaron espesor de Breslow IV. Conclusiones. El subtipo de melanoma más común en nuestra población fue el de extensión superficial; el segundo en frecuencia fue el subtipo acral lentiginoso, que se localizó siempre en extremidades. Más del 50 % de los melanomas tenían espesor de Breslow mayor o igual a III, lo que impacta en el pronóstico.

Background. Melanoma is the malignant proliferation of melanocytes associated with aggressive behavior. The objective of this study was to determine the histological variables of cutaneous melanoma. Methods. Observational, cross-sectional, descriptive, retrospective study carried out with reports of pathologies with a diagnosis of cutaneous melanoma in a pathology laboratory in Cali between 2016-2021. The variables were age, sex, location, subtype, Breslow thickness, ulceration, margins, mitosis, lymphovascular invasion, neurotropism, tumoral regression, Clark level and tumor infiltration by lymphocytes. Results. One hundred and six reports were obtained and 54 were excluded due to duplication. A descriptive analysis was made on the 52 records that were included, the mean age was 61 years, with a higher frequency in women with 55.8%. Of the 33 cases where the histological subtype was specified, the most frequent was superficial extension with 66.6%, followed by acral lentiginous with 18.1% and nodular with 15.2%. The most frequent location was in the extremities (61.5%); the most common Breslow was IV (34.6%), and the most frequent Clark was IV (34.6%). Ulceration was in 40.4%. The nodular subtype was the most aggressive presentation where 100% presented Breslow IV. Conclusions. The most common subtype of melanoma was that of superficial extension. In our population, the second most frequent was the acral lentiginous subtype, which was always located on the extremities. More than 50% of the melanomas had Breslow greater than or equal to III, which affects the prognosis.

Chromophobe renal cell carcinoma with rare distant metastasis

Metastasis accounts for the most common tumor of the central nervous system (CNS) in adults. Renal cell carcinoma (RCC) is one of the common carcinoma showing brain metastasis, with a predilection for clear cell variant. Chromophobe RCC (ChRCC) in contrast to clear cell RCC shows far less common distant metastasis. When they metastasize, commonly involve the liver, lungs, and lymph nodes. ChRCC metastasizing to the brain is extremely rare. Isolated brain metastasis from RCCs is also uncommon. We report an unusual case of a 54-year-old woman with ChRCC with isolated metastasis to the brain, 2 years after radical nephrectomy for renal mass.

Normalizing Arterial Blood Pressure in Patients with Aortic Stenosis Does Not Prevent Grading Discrepancies Between Pre?Cardiopulmonary Bypass Transesophageal Echocardiography and Transthoracic Echocardiography

Background: Aortic stenosis (AS) grading discrepancies exist between pre?cardiopulmonary (pre?CPB) transesophageal echocardiography (TEE) and preoperative transthoracic echocardiography (TTE). Prior studies have not systematically controlled blood pressure. Aims: We hypothesized that normalizing arterial blood pressure during pre?CPB TEE for patients undergoing valve replacement for AS would result in equivalent grading measurements when compared to TTE. Setting: Single University Hospital Design: Prospective, Interventional Methods: Thirty?five adult patients underwent procedures for valvular AS between February 2017 and December 2020 at Medical University of South Carolina. Study participants had a TTE within 90 days of their procedure that documented blood pressure, peak velocity (Vp ), mean gradient (PGm), aortic valve area (AVA), and dimensionless index (DI). During pre?CPB TEE, if a patient抯 mean arterial pressure (MAP) fell more than 20% below their baseline blood pressure obtained during TTE, measurements were recorded as 搊ut of range.� Phenylephrine was administered to restore MAP to the baseline range and repeat TEE measurements were recorded as 搃n?range.� Statistical Analysis: Differences between imaging modalities and grading parameters were examined using a series of linear mixed models. P values were Bonferroni?adjusted to account for multiple comparisons. Main Results: Significant discrepancies between TEE and TTE were observed for Vp , PGm, and DI despite blood pressure normalization across all subjects and for out?of?range measures and corrected measures. There were no statistically significant differences between TEE and TTE for AVA. Conclusions: Blood pressure normalization during pre?CPB TEE is not sufficient to avoid AS grading discrepancies with preoperative TTE.

Oral Submucous Fibrosis: Clinical Stage, Functional Stage, and Histopathological Grade Correlation

Background- Oral submucosal fibrosis (OSMF) is a common precancerous condition predominantly affecting the oral cavity. There are several contributing factors to its pathogenesis, areca nut chewing being the primary culprit. OSMF reversal is difficult once the disease sets in. Hence, after its diagnosis, staging becomes imperative as it affects the treatment plan. Several classification methods have been developed by various authors to categorize the disease based on its clinical, functional, and Histopathological characteristics. The main aim to conduct this study was to correlate clinical and histopathological staging. Materials & Methods- This study involved 30 patients who had been diagnosed with OSMF both Clinically and Histopathologically. All 30 patients were classified and were categorized according to their clinical and functional stages after inspection. Following this, histopathological grading was done. Results- The statistical analysis showed that there was a wide similarity between the clinical and functional staging. However, no significant similarity or correlation was found between the clinical and functional staging with its corresponding histopathological grades. Conclusions- Our study concluded that there is strong correlation between clinical and functional grading.

Evaluation of the ocular surface in asymptomatic glaucoma patients on topical medications and following trabeculectomy - A cross-sectional study

Purpose: This present prospective, cross-sectional study aims to comprehensively evaluate the ocular surface in asymptomatic patients with diffuse blebs after trabeculectomy versus chronic anti?glaucoma medication use and compare it with the age?matched normal population. Methods: Objective clinical evaluation was done by tear film break?up time (TBUT) and Schirmer’s test (ST) in the three groups– trabeculectomy >6 months with a diffuse bleb (Wurzburg bleb classification score ?10), chronic anti?glaucoma medication (AGM >6 months) group, and normal population. In all groups, tear film osmolarity was checked with the TearLab® device (TearLab Corp., CA, USA), and subjective evaluation was performed by administering Ocular Surface Disease Index (OSDI) questionnaire. Patients already on chronic lubricants or any other drug for the treatment of dry eyes (viz. steroids, cyclosporin) or having symptoms suggestive of an abnormal ocular surface, who had undergone refractive or intraocular surgery, and contact lens users were excluded. Results: In total, 104 subjects/eyes were recruited over 6 weeks. Thirty?six eyes recruited in the trab group were compared with 33 eyes studied in the AGM group, and both these groups were compared to 35 normal eyes. When compared to normals, TBUT and ST were significantly lower (P = 0.003 and 0.014) and osmolarity and OSDI were statistically significantly higher (P = 0.007 and 0.003) in the AGM group, whereas only TBUT was statistically significantly different (P = 0.009) when the trab group was compared to normals. Also, when the trab group was compared to the AGM group, ST was found to be higher (P = 0.003) and osmolarity was lower (P = 0.034). Conclusion: To conclude, ocular surface is affected even in asymptomatic patients on AGM but near normalcy is possible following trabeculectomy when blebs are diffuse.

Comparison between Anneroth’s & Broder’s Grading Systems in Oral Squamous Cell Carcinoma in Relation to Histopathological Prognostic Factors

Background: Oral squamous cell carcinoma (OSCC) is a commonly occurring head and neck cancer. It has a high prevalence, and is associated with a high mortality rate. OSCC occurs due to many etiological factors, but smoking and alcohol remain the most common risk factors. The histological grading of tumors has been used to predict the clinical behaviour of OSCC. Broder’s initiated quantitative grading in cancer. Anneroth’s and Hansen developed another grading system for grading of OSCC’s. With this background, a study was undertaken to compare between Anneroth’s & Broder’s grading systems in oral squamous cell carcinoma in relation to histopathological prognostic factors. Material & Methods: A retrospective study was carried out on 50 formalin fixed paraffin embedded tissue blocks of the confirmed cases of Oral squamous cell carcinoma in the archives of department of oral pathology, Govt. Dental College & Hospital, Srinagar. The cases were evaluated on the basis of Broder’s & Anneroth’s grading systems for OSCC & the comparison of the systems was made pertaining to histopathological prognostic parameters. Results: In our study according to Anneroth’s system maximum cases comes under grade III while in Broder’s system maximum cases are in grade I & II. Conclusion: Anneroth’s classification provides us a detailed analysis of grading the cases according to scoring of each parameter. Thus, it is more informative than Broder’s grading system.

Application and validation of a novel inflammatory score in the clinical grading of infectious endophthalmitis: The endophthalmitis management study – Report 2

Purpose: This study was conducted to describe and validate a novel inflammatory score (IS) system in the management of infectious endophthalmitis. Methods: This was a prospective comparative non?interventional observational study. The study included the patients with clinical signs and symptoms of acute post?cataract surgery endophthalmitis (surgery within 6 weeks) with visual acuity from 6/18 to light perception. IS was scored by the clinical picture at two?levels of four ocular tissues on a scale of 0 (normal) to 4 (severe). Four masked graders of different levels of experience evaluated slit?lamp photographs. The concordance correlation coefficient was assessed between the slit?lamp clinical grading and photographic grading. We measured the concordance correlation coefficient, Pearson’s correlation (indicating precision), and the bias correction factor (indicating the accuracy). Results: The study included 43 eyes of 43 patients. The concordance correlation coefficient was 0.99 (95% CI 0.995 to 0.998). Both Pearson’s correlation coefficient and the bias correction were 0.99. The interclass correlation coefficient (ICC) was measured. The intra?rater ICC was 0.833 with good agreement (95% CI, 0.711 to 0.906; P < 0.001). Inter?rater ICC for consistency was 0.92 (95% CI 0.87 to 0.95). Inter?rater ICC for absolute agreement was 0.86 (95% CI 0.66 to 0.93). Conclusion: Currently used IS scoring in the study is a reliable, reproducible, and easy?to?apply scale to measure inflammation severity in endophthalmitis. We propose that it can have applications in decision?making for primary treatment and monitoring progression in acute infectious endophthalmitis

Value of Gd-EOB-DTPA-enhanced MRI for prediction of the pathological grade and early recurrence rate of hepatocellular carcinoma / 中国基层医药

Objective:To investigate the value of gadolinium ethoxybenzyl diethylenetriaminepentaacetic acid (Gd-EOB-DTPA)-enhanced MRI in predicting the pathological grade and early recurrence rate of hepatocellular carcinoma.Methods:The imaging data, pathological data, and follow-up data of 90 patients with hepatocellular carcinoma who underwent Gd-EOB-DTPA-enhanced MRI examination and surgical treatment in People's Hospital of Baise from January 2016 to October 2017 were retrospectively analyzed. The correlation between the signal intensity of contrast-enhanced MRI and postoperative pathological grade was analyzed. Kaplan-Meier survival analysis was performed to investigate the effects of the signal characteristics of hepatobiliary lesions on the early recurrence rate of hepatocellular carcinoma.Results:A total of 59 (65.56%) patients showed low-intensity signals and 31 (34.44%) patients showed mixed-intensity signals. High-intensity signal was not found in any patients. The signal intensity of the hepatobiliary phase was significantly correlated with the pathological grade of the tumor ( χ2 = 2.26, P = 0.040) and tumor size ( t = 3.10, P = 0.033). The early recurrence rate of hepatocellular carcinoma was significantly higher in patients exhibiting mixed-intensity signals than that in patients exhibiting low-intensity signals ( χ2 = 2.25, P = 0.041). Conclusion:Gd-EOB-DTPA-enhanced MRI in the hepatobiliary phase with different signal intensities has the potential to predict the pathological grade and early recurrence rate of hepatocellular carcinoma.

Pathologic assessment of esophageal cancer following neoadjuvant therapy / 中国胸心血管外科临床杂志

@#China is a country with a high incidence of esophageal cancer. Most patients are already in the locally advanced stage when first diagnosed. Preoperative neoadjuvant therapy followed by surgery has become the standard treatment mode for them. Closely related to prognosis, the evaluation of tumor response is essential. Response evaluation criteria in solid tumors is the gold standard to evaluate tumor response, but the lesions must meet the measurement standards. Tumor regression grading (TRG) systems are designed to classify regressive changes after neoadjuvant treatment based on histopathological results to reveal prognostic information. Concentrating on pathologic assessment of esophageal cancer following neoadjuvant therapy, this article reviews histopathological changes, commonly used TRG systems and current debate.

Practice of two methods in occupational health risk grading and classification management in petroleum refining enterprises / 环境与职业医学

Background Most of the studies on grading and classification of occupational health compre-hensive risks for specific employers still remain in the establishment and description of methodology, and practical application studies are rarely reported. Objective To explore the application of an occupational disease hazards comprehensive risk assessment method issued by the National Disease Control and Prevention Bureau in conjunction with the National Health Commission and a self-developed occupational health grading and classification method in petroleum refining enterprises, and to provide practical experience for the implementation of differentiated law enforcement by relevant regulatory authorities. Methods Two occupational health grading and classification methods were practiced in three petroleum refining enterprises in Guangdong Province. The occupational hazards comprehensive risk assessment method was provided by the Notice on Carrying out Pilot Work of Occupational Health Classification Supervision and Law Enforcement of the National Disease Control and Prevention Bureau and the National Health Commission. The principle was to derive the occupational health risk level according to nature of occupational hazards, exposure level, and number of workers exposed to them in an employer, and then to classify them into Class A, Class B, and Class C by combining with local occupational health management status level. The occupational health grading and classification method was self-developed according to available domestic and foreign occupational health risk assessment methods. Its principle was to calculate the risk level of each workstation in an employer based on published carcinogenicity classification or LD50/LC50 of chemical toxicants, level of noise, exposure parameters such as exposure level and exposure frequency, estimate the comprehensive risk Ro of the target employer by the Romanian comprehensive risk calculation method, and then calculate a comprehensive risk Ro' weighted by the occupational health management index of the target employer and classify it into class A, class B, and class C. Finally, assessment results, scope of application, inquired indicators, advantages,disadvantages and professional competence requirements of the two grading and classification methods were compared. Results The occupational hazards that were evaluated in three enterprises in this study were benzene, toluene, xylene, gasoline, hydrogen sulfide, and noise. The exposure levels of benzene, toluene, xylene, and gasoline were all below 10% OEL (occupational exposure limit), and hydrogen sulfide and noise were disqualified. Occupational hazards such as benzene and hydrogen sulfide were serious occupational hazards in the three enterprises, and the number of workers exposed was 461, 912, and 224, respectively; the HRs (hazard ratings) of benzene, toluene, xylene, gasoline, hydrogen sulfide, and noise were level 5, 3, 2, 3, 5, and 3 respectively. The occupational health management status of the three enterprises was graded as B, A, and B, respectively by the occupational disease hazards comprehensive risk assessment method. The occupational health management index of the three enterprises was graded as B, A, and A, respectively by the occupational health grading and classification method. The comprehensive risk assessment results showed that two enterprises classified into as the highest class C and one into class B by the occupational disease hazards comprehensive risk assessment method, while all three enterprises were classified into class B by the occupational health grading and classification method. Conclusion The two grading and classification methods are not consistent in the evaluation results of petroleum refining enterprises, and there are differences in the evaluation scope, indicators to be collected, and professionalism. It is recommended that occupational health regulators should fully consider the advantages and disadvantages of the two methods and choose the appropriate assessment method according to the actual regulatory purpose.

Thoughts on improving comprehensive risk assessment method of occupational disease hazards of employers / 环境与职业医学

The National Disease Control and Prevention Bureau and the National Health Commission jointly issued an announcement on Notice on Carrying out Pilot Work of Occupational Health Classification Supervision and Law Enforcement, which presented a method of comprehensive risk assessment method of occupational disease hazards of employers. This method embraces relevant factors at full scale and is simple in operation, but its applicability and accuracy of assessment results need further practical study. Based on the steps of occupational health risk assessment and proven occupational health risk assessment methods available at home and abroad, this paper proposed improvements and discussed the comprehensive risk assessment method of occupational disease hazards of employers, so as to provide a technical basis to implement the occupational disease hazard classification management of employers for relevant government supervision departments.

Development and present situation of occupational health grading and classification supervision methods of employers in China / 环境与职业医学

In the face of a serious occupational disease prevention and control situation, the lack of efficient supervision and regulation methods has become a prominent contradiction. This paper reviewed the progress and application of occupational health grading and classification supervision methods for employers in China in recent years, and analyzed the characteristics and limitations of selected methods. The grading and classification supervision methods have gradually developed from considering only inherent health risk of occupational disease hazards, to considering both inherent attributes of occupational disease hazards and exposure duration. Some regional authorities introduced trial measures for grading and classification of occupational health supervision by embracing exposure level of an occupational disease hazard of interest, associated outcome severity, and occupational health management situation of targeted employers. In October 2022, the National Disease Control and Prevention Bureau issued the Notice on Carrying out Pilot Work of Occupational Health Classification Supervision and Law Enforcement, which further promoted the establishment of a differentiated occupational health supervision model. Grading and classification of occupational health supervision can improve the supervision efficiency of public health administration departments and promote employers to fulfill the main responsibility of occupational disease prevention and control.

Correlation between body mass index and elbow vein grading in patients with metabolic syndrome based on superficial vein evaluation / 中国实用护理杂志

Objective:To analyze the correlation between body mass index (BMI) and the graded expression, subcutaneous depth, and diameter of elbow veins (cephalic vein, median vein, basilic vein) in patients with metabolic syndrome, to provide a method and theoretical basis for precise puncture of peripheral veins in obese patients.Methods:From January to October 2021, a total of 767 patients with metabolic syndrome with gastric volume reduction were selected as the study subjects by retrospective cohort study from the first Affiliated Hospital of Nanjing Medical University. According to the quartile Q1, M and Q3 of BMI level, they were divided into four groups: group A, group B, group C and group D. The subcutaneous depth and diameter of the cephalic vein, median vein and basilic vein were measured by B-ultrasound, and the three veins were evaluated and graded according to the grading criteria of superficial veins.The correlation between BMI and the subcutaneous depth and diameter of the three elbow veins was analyzed, and collected data such as puncture method and puncture times. Results:There was no significant correlation between BMI and subcutaneous depth and vessel diameter of the basilic vein ( r = 0.041 and 0.046, both P>0.05), the level of BMI was positively correlated with the subcutaneous depth and diameter of cephalic vein ( r = 0.275 and 0.117, both P<0.05) and median vein ( r = 0.236 and 0.148, both P<0.05), and a linear regression relationship was found ( OR values were 1.013-1.031, all P<0.05). 187 cases had direct puncture conditions under direct vision, and the success rate of one puncture was 86.63%(162/187).Venipuncture was completed under the guidance of B-mode ultrasound for 25 cases with failure under direct vision and 580 cases without direct puncture conditions under direct vision, the success rate of one puncture was 98.51% (596/605). Conclusions:With the increase of BMI level in patients with metabolic syndrome, the depth and diameter of both cephalic vein and median vein increase, venous exposure is difficult to express. The visual vein puncture guided by B-ultrasound is more accurate and catheterization is more reliable.

Quantitative grading evaluation of the therapeutic efficacy of asymmetric bilateral lateral rectus recession in type Ⅲ Duane retraction syndrome / 国际眼科杂志(Guoji Yanke Zazhi)

AIM: To quantitatively evaluate the therapeutic efficacy of the asymmetric recession of bilateral lateral rectus in patients with unilateral type III Duane retraction syndrome.METHOD:Retrospective analysis of clinical data. The clinical data of 12 cases of type III Duane retraction syndrome with unilateral lateral rectus recession were analyzed. All subjects had restricted internal rotation, with narrowing of the palpebral fissure and vertical deviation, and restricted external rotation with widening of the palpebral fissure. All patients had abnormal head positions. The degree of strabismus was measured while maintaining the head in a neutral position. Asymmetric recession of bilateral lateral rectus was selected based on the degree of strabismus of affected eye or 1～3mm longer, with a smaller recession and Y-splitting in the affected eye and a larger recession in the healthy eye.RESULT:The difference in the degree of strabismus in the healthy eyes before and after surgery was statistically significant(Z=-4.158, P&#x003C;0.01), as was the difference in the degree of restricted internal rotation(Z=-2.640, P=0.008). The difference in the degree of restricted external rotation was not statistically significant(Z=-1.732, P=0.083). The difference in abnormal head position was statistically significant(Z=-4.181, P&#x003C;0.01), while the difference in eyeball recession was not statistically significant(Z=-1.414, P=0.157). The difference in vertical deviation was statistically significant(Z=-3.115, P=0.002). A total of 10 patients(83%)had stereoscopic vision before surgery, and 11 patients(92%)had recovered stereoscopic vision after surgery, with a further improvement in stereoacuity in 50% of patients.CONCLUSION:Asymmetric recession of bilateral lateral rectus combined with Y-splitting of the affected lateral rectus can effectively improve the degree of strabismus, abnormal head position, vertical deviation and stereoacuity without aggravating the degree of restriction of external rotation or eyeball recession.

Re-evaluation of systematic reviews of acupuncture and moxibustion for childhood autism / 中国针灸

OBJECTIVE@#To re-evaluate the systematic review/Meta-analysis of acupuncture and moxibustion for childhood autism (CA), aiming to provide decision-making basis for clinical diagnosis and treatment.@*METHODS@#The systematic review and/or Meta-analysis of acupuncture and moxibustion for CA were searched in PubMed, EMbase, Cochrane Library, SinoMed, CNKI and Wanfang databases. The retrieval time was from the database establishment to May 5th, 2022. PRISMA (preferred reporting items for systematic reviews and Meta-analyses) was used to evaluate the report quality, and AMSTAR 2 (a measurement tool to assess systematic reviews 2) was used to evaluate the methodological quality, bubble map was used to construct the evidence map and GRADE was used to evaluate the quality of evidence.@*RESULTS@#A total of 9 systematic reviews were included. The PRISMA scores ranged from 13 to 26. The report quality was low, and there was a serious lack in the aspects of program and registration, search, other analysis and funding. The main problems in methodology included not making prespecified protocol, incomplete retrieval strategy, not providing a list of excluded literatures, and incomplete explanation on heterogeneity analysis and bias risk. The evidence map showed that 6 conclusions were valid, 2 conclusions were possible valid and 1 conclusion was uncertain valid. The overall quality of evidence was low, and the main factors leading to the downgrade were limitations, followed by inconsistency, imprecision and publication bias.@*CONCLUSION@#Acupuncture and moxibustion has a certain effect for CA, but the quality of reporting, methodology and evidence in included literature need to be improved. It is suggested to perform high-quality and standardized research in the future to provide evidence-based basis.

Overview of systematic reviews of Chinese herbal injections for sepsis / 中国中药杂志

In this study, an overview of systematic reviews/Meta-analysis(SR/MA) of Chinese herbal injections for sepsis was performed to provide references for clinical practice and promote the quality improvement of clinical evidence. Eight Chinese and English databases such as CNKI, Medline, and EMbase were electronically searched for SR/MA of Chinese herbal injections for sepsis from database inception to June 2022. AMSTAR 2, PRISMA 2020, and GRADE system, combined with Recommendations for Clinical Evidence Grading on Traditional Chinese Medicine Based on Evidence Body, were applied to evaluate the methodological quality, reporting quality, and evidence quality of the included articles. Twenty-seven articles of SR/MA were included, containing four Chinese herbal injections(Xuebijing Injection, Shenfu Injection, Shenmai Injection, and Shengmai Injection). AMSTAR 2 checklist showed that the methodological quality of the SR/MA ranged from moderate to very low. Item 2(prior study design) was the critical item with poor scores, and the non-critical items with poor scores were items 3(explain the selection of the study designs), items 10(report on the sources of funding), and items 16(conflicts of interest stated). In terms of PRISMA 2020, items in eight topics with complete reporting of missing>50%, including search strategy, certainty assessment, results of syntheses, certainty of evidence, registration and protocol, support, competing interests, availability of data, code and other materials. The included SR/MA involved 30 outcome indicators. Evidence quality of mortality, APACHE Ⅱ, and safety, the top three outcome indicators, was evaluated, and all of them were graded as the medium level. The lack of random allocation sequence, allocation concealment mechanism, blinding, and trial sample size was the main reason for the reduction of the evidence level. The available evidence shows that Chinese herbal injections can serve as an effective and safe adjunctive treatment for sepsis, which can reduce mortality, inhibit inflammation, improve coagulation function, and regulate immune function, tissue perfusion, and oxygenation in patients with sepsis. However, the quality of SR/MA was suboptimal, and more high-quality SR/MA is needed to provide evidence to support the efficacy and safety of Chinese herbal injections in the treatment of sepsis.

La intensidad de la captación intraprostática del PSMA como predictor de cáncer de próstata clínicamente significativo / The intensity of PSMA intraprostatic uptake as a predictor of clinically significant prostate cancer

Resumen Introducción: La tomografía por emisión de positrones (PET) con antígeno de membrana específico de próstata (PSMA) mejora la estadificación del cáncer de próstata. Además, la intensidad de captación intraprostática del PSMA puede predecir resultados oncológicos clínicamente relevantes. Nuestro objetivo fue evaluar si la intensidad de captación de PSMA se asocia con el cáncer de próstata clínicamente significativo y poder conocer qué valor de captación de PSMA discrimina mejor esta relación. Métodos: Se realizó un estudio de cohorte de 40 pacientes con cáncer de próstata comprobado por biopsia previo a la realización de radioterapia externa. Se evaluó correlación entre intensidad de captación del PSMA intraprostático y los resulta dos patológicos adversos en la biopsia prostática. Se estudió qué valor de captación de PSMA discrimina mejor el cáncer de próstata clínicamente significativo utilizando curvas ROC. Resultados: El 40% de los pacientes tuvieron un cáncer de próstata clínicamente significativo, el maximum standardized uptake value (SUV max) tuvo una media de 11.5 (DE ± 7). La muestra arrojó un coeficiente de correlación Spearman de 0.4 (p = 0.007). El área bajo la curva (AUC) fue de 0.73, mostrando el punto de corte un SUV max ≥ 9.5, sensibilidad 0.81 y especificidad 0.71 en la detección de cáncer de próstata clínicamente significativo. Conclusión: la intensidad de captación del PSMA intraprostático puede ser una nueva herramienta diagnóstica en la detección del cáncer de próstata clínicamente significativo. Una intensidad de captación ≥ 9.5 tuvo una buena correlación con el cáncer de próstata clínicamente significativo.

Abstract Introduction: Positron emission tomography (PET) with prostate-specific membrane antigen (PSMA) improves prostate cancer staging. Furthermore, the intensity of intraprostatic uptake of PSMA can predict clinically relevant oncologic outcomes. The objective of this study is to evaluate whether the intensity of PSMA uptake is associated with clinically significant prostate cancer and to determine which value of PSMA uptake best dis criminates this relationship. Methods: A cohort study of 40 patients with biopsy-proven prostate cancer prior to external radiotherapy was conducted. The correlation between intraprostatic PSMA uptake intensity and adverse pathological findings in prostate biopsy was evaluated. Which PSMA uptake value better discriminates clinically significant prostate cancer was assessed using ROC curves. Results: Forty percent of the patients had a clinically significant prostate cancer and the maximum standardized uptake value (SUV max) had a mean of 11.5 (SD ± 7). The sample showed a Spearman correlation coefficient of 0.4 (p = 0.007). The area under the curve (AUC) was 0.73 and a SUV max ≥ 9.5 showed a sensitivity of 0.81 and a specificity of 0.71 in the detection of clinically significant prostate cancer. Conclusion: Intraprostatic PSMA uptake intensity can be a new diagnostic tool in the detection of clinically significant prostate cancer. An uptake intensity equal or greater than 9.5 is correlated with clinically significant prostate cancer.
