A subclassification of TNBC has been proposed into four subgroups, one of which is the luminal androgen receptor. The objective of this work was to determine the expression of the androgen receptor (AR) in women with TNBC, diagnosed by immunohistochemistry, at the Hospital Metropolitano del Norte, Valencia, Venezuela. The sample consisted of 191 pa-tients who met the inclusion criteria. The mean age of the patients at the time of diagnosis was 54.91 years. Histologically, the majority of the tumors were moderately differentiated or undifferentiated. The percentage of AR expres-sion was 22% (42 of 191). In the association between AR expression and the Ki-67 proliferative index, a greater number of AR positive cases was observed in tumors with Ki-67 expression of less than 40%. The AR positivity found in this study represents an intermediate frequency in relation to other investigations. No statistically significant differences were found with the age of the patients and histological grade of the tumors, while the Ki-67 proliferative index was lower for AR+ tumors, compared to TNBC in general.","PeriodicalId":14515,"journal":{"name":"Investigación Clínica","volume":"229 ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-02-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140453272","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Abdominal ultrasound helps diagnose it and differentiate it from other causes of abdominal pain. This study aimed to evalu-ate the diagnostic value of abdominal ultrasound in acute appendicitis (AA) and assess inflammatory factor levels in different types of appendicitis. One hundred patients with AA were selected as the observation group, and 30 pa-tients with simple abdominal pain as the control group. Among the 100 AA patients, 37 (37%) cases had blurred appendiceal boundaries, 24 (24%) cases had fecal calculus in the appendix cavity, 13 (13%) cases had enhanced echo intensity of surrounding fat, 15 (15%) cases presented enlarged outer diameter of the appendix (> 6mm), one (1%) case had peripheral lymphadenopathy, and one (1%) case had peripheral effusion. None of the cases (0%) presented a pe-ripheral mass. The levels of white blood cells (WBC) and inflammatory factors: C-reactive protein (CRP), interleukin-6 (IL -6), and tumor necrosis factor α(TNF-α)) patients with uncomplicated appendicitis were lower than those with suppurative appendicitis, gangrenous appendicitis, or peri-appendiceal abscess (p <0.05). The blurred boundary of the appendix, fecal stones in the appendix cavity, an enlarged outer diameter of the appendix (> 6mm), and an enhanced echogenicity of the surrounding fat are the most common ultrasonic signs of AA. Abdominal ultrasound has an excellent diagnostic value on pathological types of AA. The increase in the level of inflammatory factors can indicate the severity of the disease to a certain extent.","PeriodicalId":14515,"journal":{"name":"Investigación Clínica","volume":"118 ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-02-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140453290","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The rejection percentage was 36%. The evaluation of the work of the members of the Editorial Committee had the collaboration of external referees from national and foreign institutions, especially Venezuelans living abroad. The magazine fulfilled its frequency of four issues with 41 communications in 559 pages, exceeding the number of pages from the previous year. Among the 41 works, the original works in English predominated, both from Venezuela and Latin America and countries on other continents. In evaluating the magazine by international indices, the increase in the Copernicus Index score stands out due to excellent compliance with their classification patterns. There were discrepancies between the different indexes in the citations; Clarivate reported 204, and Sco-pus only 20. Scopus recognizes only 44 citations in the four years (2019-2022), and Scielo recognizes 498 in that same period. The Crossref report was of more than 13,000 accesses in 2023, with Spanish-language Reviews being the most frequent, which suggests that Latin America is the primary source of readers for the magazine. This observation corroborates the results of our website, where the main accesses come from American countries. We hope that in 2024, Investigación Clínica will increase its national and international recognition; it would be a gift to the memory of its founder, Américo Negrette, who would be celebrating the centenary of his birth in 2024.","PeriodicalId":14515,"journal":{"name":"Investigación Clínica","volume":"58 14","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-02-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140453751","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Favipiravir is used in high doses to treat COVID-19 but has a side effect on humans at high doses. The side effects of favipiravir have been associated with oxidative stress in the literature. In this trial, we investigated the biochemical and histopathological effects of lacidip-ine, thiamine pyrophosphate (TTP), and adenosine triphosphate (ATP), drugs with antioxidant properties, on the lung toxicity caused by high-dose favipiravir in rats. The rats were classified into five groups: healthy (HG), favipiravir alone (Fav), lacidipine+favipiravir (LFav), TPP+favipiravir (TFav), and ATP+favipiravir (AFav). Favipiravir (800 mg/kg) was administered twice daily for seven days. Laci-dipine (4 mg/kg), TPP (20 mg/kg), and ATP (25 mg/kg) were administered once daily for seven days. Oxidant (malondialdehyde), non-enzymatic (total glutathi-one), and enzymatic (superoxide dismutase and catalase) antioxidant levels were measured in the excised lung tissues. Furthermore, the tissues were histopatho-logically examined. The systemic administration of high doses of favipiravir in-creased oxidant levels and decreased antioxidant levels in the lung tissue of rats. In parallel, the histopathological examination of the lung tissue revealed the presence of severe mononuclear cell infiltrations in interstitial areas and pronounced lymphoid hyperplasia. Lacidipine exhibited superior efficacy in mit-igating oxidative stress and preventing the decline of antioxidants induced by favipiravir compared with TPP and ATP. Histopathologically, the lacidipine admin-istration significantly reduced lung oxidative damage. TTP moderately reduced severe favipiravir-associated lung injury. However, ATP was ineffective against fa-vipiravir-associated lung injury. Lacidipine offers more therapeutic benefits than TPP in treating oxidative lung injury caused by high doses of favipiravir.","PeriodicalId":14515,"journal":{"name":"Investigación Clínica","volume":"65 7","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-02-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140453574","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This article aimed to investigate the fractional exhaled carbon monoxide (FeCO) expression level in obstructive sleep apnea-hypopnea syndrome (OSAHS) and its correlation with disease indicators. Subjects with OSAHS, asthma, chronic obstructive pulmonary disease (COPD), and healthy subjects were selected to collect clinical data. FeCO concentration, eosinophil (Eos), erythrocyte sed-imentation rate (ESR), C-reactive protein (CRP), FEV1, and FEV1/FVC were measured. The Pearson correlation coefficient and receiver operating charac-teristic (ROC) curve were used for statistical analysis. The FeCO concentra-tion, Eos count, ESR and CRP levels, and lung function in the OSAHS group were higher than the healthy and COPD groups (p<0.05) and slightly lower than the asthma group. FeCO was positively correlated with Eos, ESR, and CRP (p<0.05), but there was no apparent correlation between FeCO and lung func-tion. FeCO has a high sensitivity and specificity in the diagnosis of OSAHS. There is chronic airway inflammation and systemic inflammation in patients with OSAHS. Lung function impairment in patients with OSAHS is mild, but some limitations remain.

This study aimed to investigate the effect of experimental folic acid administration on N-methyl-N’-nitro-N-nitrosoguanidine (MNNG)-induced CAG through the PI3K/Akt pathway in rats. The rats were divided into a Model Group, a Folic Acid Group and a Blank Group. Rats in the Model Group were induced by MNNG and given 10 mL/kg/d distilled water by gavage, while rats in the Folic Acid Group were induced by MNNG and given 5 mg/kg/d folic acid suspension by gavage. As a control, rats in the Blank Group were given the same amount of distilled water as MNNG and 10 mL/kg/d distilled water by gavage. The levels of gastrin (GAS) and motilin (MTL) in serum were measured by enzyme-linked immunosorbent assay (ELISA), and the mRNA and protein ex-pressions were detected by quantitative polymerase chain reaction (q-PCR) and Western blot. According to hematoxylin and eosin (H&E) pathological analysis, there were inflammatory factors infiltration and derangement of mucosal epi-thelial cells in the model group, while the gastric tissue injury in the folic acid group was improved. Folic acid could decrease the content of GAS, increase the content of MTL in the serum of the rats, and regulate the expression of PI3K and AKT signal pathways. Folic acid can have a therapeutic effect on CAG by reducing the concentration of GAS in serum and increasing the concentration of MLT in serum. Our study would lay a theoretical foundation for using folic acid to investigate new therapies for CAG in humans.","PeriodicalId":14515,"journal":{"name":"Investigación Clínica","volume":"384 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-02-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140453715","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Seventy TBI patients admitted between January 2020 and January 2021 were catego-rized into good prognosis (n=42) and poor prognosis (n=28) groups according to the Glasgow Outcome Scale (GOS) score upon discharge. Factors affecting prognosis were analyzed, and differences in intracranial pressure and coagula-tion between the two groups were compared. The receiver operating charac-teristic curve (ROC) was used to calculate the predictive value of intracranial pressure-related parameters and coagulation function on prognosis. Within 24 h postoperatively, the good prognosis group had lower levels of intracra-nial pressure (ICP) and partial pressure of oxygen in brain tissue (PbtO2) and higher cerebral perfusion pressure (CPP) and cerebral hemodynamic param-eters than the poor prognosis group (p<0.05). The good prognosis group had significantly lower prothrombin time (PT), activated partial thromboplastin time (aPTT),and prothrombin time (TT) levels and higher platelets (PLT) and fibrinogen (Fib) levels than the poor prognosis group (p<0.05). Regression analysis revealed that CPP, systolic blood flow velocity (Vs), end-diastolic blood flow velocity (Vd), mean blood flow velocity (Vm), PLT, Fib were independent protective factors for the prognosis, and ICP, PbtO2, PT, APTT, and TT were risk factors for prognosis. The ROC revealed that ICP, CPP, PbtO2, Vs, Vd, Vm, APTT, PLT, Fib exhibited high diagnostic value for poor prognosis (AUC=0.732, 0.940, 0.796, 0.706, 0.914, 0.729, 0.876, 0.709, 0.866), with ICP showing the highest diagnostic sensitivity and Vd showing the highest diagnostic specificity.
