Breast carcinoma of the triple-negative subtype (TNBC) does not express estrogen, progesterone or human epidermal growth factor recep-tor 2 (HER2) receptors. 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.
三阴性亚型乳腺癌(TNBC)不表达雌激素、孕激素或人类表皮生长因子受体 2(HER2)受体。有人提出将 TNBC 划分为四个亚组,其中一个是腔内雄激素受体亚组。这项研究的目的是确定在委内瑞拉巴伦西亚北大都会医院(Hospital Metropolitano del Norte)通过免疫组化确诊的 TNBC 女性患者中雄激素受体(AR)的表达情况。样本包括191名符合纳入标准的患者。患者确诊时的平均年龄为 54.91 岁。从组织学角度来看,大多数肿瘤属于中度分化或未分化。AR表达率为22%(191例中有42例)。在AR表达与Ki-67增殖指数之间的关系中,Ki-67表达低于40%的肿瘤中AR阳性病例较多。与其他研究相比,本研究发现的 AR 阳性率属于中等水平。与一般TNBC相比,AR+肿瘤的Ki-67增殖指数较低,但与患者的年龄和肿瘤的组织学分级没有统计学差异。

Appendicitis is an inflammation of the appendix that, if left un-treated, can be life-threatening. 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.
阑尾炎是阑尾的一种炎症,如果不及时治疗,可能会危及生命。腹部超声波有助于诊断阑尾炎,并将其与其他原因引起的腹痛区分开来。本研究旨在评估腹部超声波对急性阑尾炎(AA)的诊断价值,并评估不同类型阑尾炎的炎症因子水平。研究选取 100 名急性阑尾炎患者作为观察组,30 名单纯腹痛患者作为对照组。在 100 例 AA 患者中,37 例(37%)阑尾边界模糊,24 例(24%)阑尾腔内有粪便结石,13 例(13%)阑尾周围脂肪回声强度增强,15 例(15%)阑尾外径增大(> 6 毫米),1 例(1%)阑尾周围淋巴结肿大,1 例(1%)阑尾周围渗液。没有一个病例(0%)出现阑尾肿块。白细胞(WBC)和炎症因子的水平:无并发症阑尾炎患者的白细胞(WBC)和炎症因子:C 反应蛋白(CRP)、白细胞介素-6(IL-6)和肿瘤坏死因子α(TNF-α)的水平低于化脓性阑尾炎、坏疽性阑尾炎或阑尾周围脓肿患者(P 6mm),周围脂肪的回声增强是 AA 最常见的超声波征象。腹部超声对病理类型的 AA 有很好的诊断价值。炎症因子水平的升高可在一定程度上显示疾病的严重程度。

This narrative review analyzed the relationship between cervical cancer and the vaginal microbiome. It has been estimated that viruses and bac-teria cause 15% of all cancers. The development of molecular biology, genetics, and the use of high-throughput genomic sequencing techniques has allowed us not only to know the phenotypic component but also the genetic component of the vaginal microbiome and obtain a better knowledge and understanding of the behavior of the vaginal flora that was previously impossible to determine. The relation of the alterations in the vaginal flora by women’s habits, immunological status, and socioeconomic level has been established. Literature searches were performed electronically in PubMed, Medline, ISI, DOAJ, Springer, Embase, Web of Knowledge, and Google Scholar for original articles written in English and Sci-elo, Latindex, Imbiomed-L, Redalyc, and Google Scholar for original articles writ-ten in Spanish. The objective of this narrative review was to examine and analyze the literature on the alterations in the vaginal microbiome, their local protective effect and their possible contribution to the development of cervical cancer.
这篇叙述性综述分析了宫颈癌与阴道微生物组之间的关系。据估计,15% 的癌症是由病毒和细菌引起的。分子生物学、遗传学的发展以及高通量基因组测序技术的使用,使我们不仅能够了解阴道微生物组的表型成分,还能了解其遗传成分,并对以前无法确定的阴道菌群行为有了更好的认识和理解。阴道菌群的改变与妇女的生活习惯、免疫状态和社会经济水平之间的关系已经确定。通过电子方式在 PubMed、Medline、ISI、DOAJ、Springer、Embase、Web of Knowledge 和 Google Scholar 搜索英文原文,并在 Sci-elo、Latindex、Imbiomed-L、Redalyc 和 Google Scholar 搜索西班牙文原文。这篇叙述性综述的目的是研究和分析有关阴道微生物组的改变、其局部保护作用以及可能导致宫颈癌发生的文献。

The main achievement of the journal in 2023 was an increase in the number of works received, mainly of foreign origin. 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.
