Frailty does not affect prognostic markers in patients with acute coronary syndrome: results from a Brazilian university hospital

OBJECTIVE: To evaluate frailty and its relationship with prognostic markers in hospitalized patients with acute coronary syndrome. METHODS: This cross-sectional study with a prospective variable analysis (prognostic markers) involved adults of both sexes aged ≥ 50 years with acute coronary syndrome. Patients with ≥ 3 of the following criteria were considered frail: 1) unintentional weight loss; 2) exhaustion (assessed by self-reported fatigue); 3) low handgrip strength; 4) low physical activity level; and 5) low gait speed. The included prognostic markers were: metabolic changes (lipid and glycemic profile), changes in inflammatory status (C-reactive protein), thrombolysis in myocardial infarction risk score, troponin level, angioplasty or surgery, hospitalization in the intensive care unit, length of hospital stay, and hospital outcome. RESULTS: The sample consisted of 125 patients, whose mean age was 65.5 (SD, 8.7) years. The prevalence of frailty was 48.00%, which was higher in women (PR = 1.55; 95%CI 1.08­2.22; p = 0.018) and patients with systemic arterial hypertension (PR = 2.18; 95%CI 1.01­5.24; p = 0.030). Frailty was not associated with age, cardiac diagnosis, or prognostic markers (p > 0.05). CONCLUSIONS: Frailty was highly prevalent in patients with acute coronary syndrome, affecting almost half of the sample, particularly women and patients with hypertension, irrespective of age. However, despite its high prevalence, frailty was not associated with markers of metabolic change or poor prognosis.

Clinical diagnosis， treatment， and prognosis of gallbladder sarcomatoid carcinoma： An analysis of 16 cases / 临床肝胆病杂志

ObjectiveTo investigate the clinicopathological features， diagnosis and treatment methods， and prognosis of gallbladder sarcomatoid carcinoma （GBSC）. MethodsA retrospective analysis was performed for the clinical data of 16 patients with GBSC who were admitted to The First Affiliated Hospital of Zhengzhou University from January 2015 to April 2023， including general information， clinical manifestations， imaging features， pathological features， and treatment modality， and follow-up was performed for all patients. The Kaplan-Meier method was used to perform the survival analysis and plot the survival curve， and the Log-rank test was used for comparison between groups. ResultsAmong the 16 patients， there were 6 male patients and 10 female patients， with a mean age of 62.9±8.4 years. The main clinical manifestations were right upper abdominal pain in 13 patients （81.3%）， nausea in 5 patients （31.3%）， abdominal distension in 4 patients （25.0%）， poor appetite in 3 patients （18.8%）， weakness in 2 patients （12.5%）， fever in 2 patients （12.5%）， and jaundice in 1 patient （6.3%）， and 3 patients were asymptomatic and were found to have this disease by physical examination. Of all patients， 81.3% （13/16） were in the advanced stage （stage Ⅲ/Ⅳ） at the time of initial diagnosis. Histopathological examination showed that some cancer cells were spindle-shaped under the microscope， with marked nuclear division and noticeable heteromorphism. Immunohistochemistry showed a positive expression rate of 100% （16/16） for Vimentin， AE1/AE3， and CK8/18， and Ki-67 proliferation index was highly expressed in 81.3% （13/16） of the patients （≥50%）， with a median of 70% （range 20%‍ ‍—‍ ‍90%）. All 16 patients underwent surgical treatment， with radical surgery in 11 patients and palliative surgery in 5 patients， among whom 9 received R0 resection， 2 received R1 resection， and 5 received R2 resection， and 7 patients received adjuvant therapy after surgery. Effective follow-up was achieved for all 16 patients， with a follow-up time of 0.5‍ ‍—‍ ‍26.0 months and a median follow-up time of 11.0 months. By the end of follow-up， 2 patients survived and 14 patients died due to tumor recurrence or metastasis， with a median survival time of 10.0 months， and the 1- and 2-year cumulative survival rates after surgery were 31.3% and 8.3%， respectively. The prognostic analysis showed that TNM stage （χ2=6.727， P=0.009）， surgical approach （χ2=7.508， P=0.006）， margin condition （χ2=7.934， P=0.005）， and adjuvant therapy （χ2=4.608， P=0.032） were associated with the prognosis of patients. ConclusionThe clinical manifestations of GBSC lack specificity， and a confirmed diagnosis relies on immunohistochemical analysis. Most patients are in the advanced disease at the time of initial diagnosis and tend to have a poor prognosis. There are currently no targeted therapies for this disease， and radical surgery with negative margins and adjuvant therapy can improve the survival rate of patients.

@#Objective To summarize and analyze the clinical diagnosis, surgical treatment and prognosis of multiple pulmonary nodules (MPNs). Methods The clinical data of lung cancer patients who received surgical treatment in our hospital from 2018 to 2020 were collected. The short-term efficacy of surgical treatment for MPNs was analyzed. Results A total of 97 patients were enrolled, including 30 males and 67 females with an average age of 56.1±10.0 years at onset ill. There were 62 patients with double lesions, 22 patients with three lesions, 4 patients with four lesions, and 9 patients with more than four lesions. A total of 213 lesions were surgically treated, including 88 pure ground-glass nodules, 81 partially solid nodules, and 7 solid nodules. There were 87 simultaneous surgeries and 10 staged surgeries, with an average operation interval of 5.2 months. The pathological combination type included adenocarcinoma-adenocarcinoma in 96 (99.0%) patients, squamous cell carcinoma-squamous cell carcinoma in 1 (1.0%) patient, and no lymph node metastasis was found. The 2-year disease-free survival (DFS) rate was 92.1%, and the overall survival (OS) rate was 100.0%. Univariate analysis showed that high-risk lesion size>2 cm (P=0.316), residual lesions (P=0.782) and pathological combination type (P=0.913) had statistical effect on the 2-year DFS rate. Conclusion MPNs are mainly diagnosed with multiple primary lung cancers, and the pathological combination is mostly adenocarcinoma-adenocarcinoma combination. Imaging examination is of great help to the surgical approach selection, diagnosis and differential diagnosis of MPNs. During the operation, maximal preservation of lung function and complete resection of high-risk nodules should be taken as the principle, and the prognosis is satisfactory.

Chronic hepatitis B virus infection and metabolic associated fatty liver disease： The known and unknown aspects / 临床肝胆病杂志

Chronic hepatitis B virus （HBV） infection is the main cause of the disease burden of viral hepatitis worldwide， and meanwhile， due to changes in lifestyle and dietary habits， the incidence rate of metabolic associated fatty liver disease （MAFLD） is constantly increasing， making MAFLD the leading chronic liver disease around the world. Chronic HBV infection comorbid with MAFLD is becoming more and more common in clinical practice. Metabolic factors， rather than viral factors， are the main cause of chronic HBV infection comorbid with MAFLD. During disease progression， steatohepatitis and fibrosis， rather than steatosis， are the main influencing factors for the progression to liver cirrhosis and hepatocellular carcinoma. For patients with chronic HBV infection and MAFLD， integrated management of virus and metabolic factors is of great importance. This article reviews the tissues regarding the interaction， prognosis， and clinical management of chronic HBV infection and MAFLD.

Objective To explore the imaging features, clinical outcome, and prognosis of indeterminate pulmonary nodules (IPN) in patients with high-grade soft tissue sarcoma. Methods A retrospective study of 82 patients with high-grade soft tissue sarcoma who have IPNs. The clinical characteristics, imaging features of IPN, and survival of patients were analyzed with statistical software. Results The IPN size of 82 patients was 6.453±0.864 mm. IPN diameter, shape, density, and nodule discovery interval may be CT imaging features related to malignancy tendency. Age (HR=1.047, 95%CI: 1.007-1.088) and interval between each nodule discovery (HR=3.194, 95%CI: 1.052-9.694) are independent factors that affect the survival of patients with malignant IPN. Conclusion The imaging features of chest CT may provide important guidance for determining the nature and survival prognosis of benign and malignant nodules.

Expression and Clinical Significance of MKI67 in Pancreatic Cancer / 肿瘤防治研究

Objectives To explore the expression, biological function, and mechanism of MKI67 in pancreatic cancer and its clinical significance. Methods The expression level, diagnosis, and prognostic value of MKI67 in pancreatic cancer were analyzed using public databases. We also investigated the association between the MKI67 with immune cell infiltration and immune checkpoint molecules. We analyzed the functional pathway enrichment to uncover the possible molecular mechanisms. qRT-PCR and Western blot assay were used to verify the expression of MKI67 mRNA and protein. Immunohistochemistry staining was used to detect the expression of MKI67 in tissue protein. Results The high expression of MKI67 was significantly associated with high histological grades and poor outcomes in pancreatic cancer. High MKI67 expression was correlated with poor prognosis of pancreatic cancer patients (P=0.009). MKI67 was an independent risk factor for the patient outcome (95%CI: 1.084-1.743, P<0.05). The MKI67 expression was positively correlated with the helper T cell 2 levels but negatively correlated with plasmacytoid DC, NK cells, mast cells, the T follicular helper, immune DC, and CD8 T cells. Conclusion MKI67 may serve as a biomarker for the diagnosis and prognosis of pancreatic cancer and the mechanism might be associated with immune escape or immunosuppression.

Combined Therapies of Traditional Chinese Medicine Treat Low-prognosis Patients Undergoing IVF-ET Again / 中国实验方剂学杂志

ObjectiveTo objectively evaluate the clinical efficacy of multiple therapies of traditional Chinese medicine （TCM） in low-prognosis patients who received antagonist protocol for in vitro fertilization and embryo transfer （IVF-ET） again. MethodA total of 128 patients with kidney Yin deficiency， liver depression， and blood stasis who planned to receive antagonist protocol for IVF-ET in the West China Second Hospital of Sichuan University were enrolled and assigned into two groups by random number table method. The observation group （64 casces） was treated by oral administration of Chinese medicine decoction + enema of kidney-tonifying and blood-activating method + auricular point sticking + oral administration of dehydroepiandrosterone （DHEA）， while the control group （64 casces） was treated by only oral administration of DHEA. After treatment for three menstrual cycles， both groups received the antagonist protocol for IVF-ET. The TCM syndrome scores， basic sex hormone levels， antral follicle count （AFC）， the usage of gonadotropin （Gn）， endometrial receptivity indicators， embryo quality indicators， and pregnancy outcomes were compared between the two groups. ResultAfter treatment， the observation group showed decreased follicle-stimulating hormone （FSH）/luteinizing hormone （LH） ratio， lowered level of estradiol （E2）， increased AFC， decreased amount and days of Gn usage， improved endometrial receptivity indicators （endometrial thickness on trigger and ET days， proportion of endometrial type A in endometrial types and the level of E2 on trigger day） and embryo quality indicators （the rates of mature follicles， fertilization， normal fertilization， and premium embryos）， and decreased TCM syndrome scores （P<0.05， P<0.01）. Moreover， the observation group had lower FSH/LH ratio， E2 level， and amount of Gn usage， higher AFC， poorer endometrial receptivity and embryo quality indicators， and lower TCM syndrome scores than the control group after treatment （P<0.05， P<0.01）. In addition， except for 3 cases of natural pregnancy， the observation group outperformed the control group in terms of improving the clinical pregnancy rates during initiation cycle and transplantation cycle and clinical pregnancy rate and decreasing biochemical pregnancy rate and early abortion rate （P<0.05）. ConclusionCombined therapies of TCM can alleviate the clinical symptoms， reduce TCM syndrome scores， reduce the Gn usage amount， improve the number and quality of embryos and endometrial receptivity， and coordinate the synchronous development of endometrium and embryo. In this way， they can increase the clinical pregnancy rate and reduce biochemical pregnancy rate and early abortion rate in the low prognosis patients with kidney yin deficiency， liver depression， and blood stasis who are undergoing IVF-ET again.

Construction of a Prognostic Prediction Model of Patients with Pathologic N0 in Resected Invasive Mucinous Adenocarcinoma of the Lung / 中国肺癌杂志

BACKGROUND@#Invasive mucinous adenocarcinoma (IMA) was a rare and specific type of lung adenocarcinoma, which was often characterized by fewer lymphatic metastases. Therefore, it was difficult to evaluate the prognosis of these tumors based on the existing tumor-node-metastasis (TNM) staging. So, this study aimed to develop Nomograms to predict outcomes of patients with pathologic N0 in resected IMA.@*METHODS@#According to the inclusion criteria and exclusion criteria, IMA patients with pathologic N0 in The Affiliated Lihuili Hospital of Ningbo University (training cohort, n=78) and Ningbo No.2 Hospital (validation cohort, n=66) were reviewed between July 2012 and May 2017. The prognostic value of the clinicopathological features in the training cohort was analyzed and prognostic prediction models were established, and the performances of models were evaluated. Finally, the validation cohort data was put in for external validation.@*RESULTS@#Univariate analysis showed that pneumonic type, larger tumor size, mixed mucinous/non-mucinous component, and higher overall stage were significant influence factors of 5-year progression-free survival (PFS) and overall survival (OS). Multivariate analysis further indicated that type of imaging, tumor size, mucinous component were the independent prognostic factors for poor 5-year PFS and OS. Moreover, the 5-year PFS and OS rates were 62.82% and 75.64%, respectively. In subgroups, the survival analysis also showed that the pneumonic type and mixed mucinous/non-mucinous patients had significantly poorer 5-year PFS and OS compared with solitary type and pure mucinous patients, respectively. The C-index of Nomograms with 5-year PFS and OS were 0.815 (95%CI: 0.741-0.889) and 0.767 (95%CI: 0.669-0.865). The calibration curve and decision curve analysis (DCA) of both models showed good predictive performances in both cohorts.@*CONCLUSIONS@#The Nomograms based on clinicopathological characteristics in a certain extent, can be used as an effective prognostic tool for patients with pathologic N0 after IMA resection.

Neonatal lupus erythematosus (NLE) is caused by the transmission of maternal anti-Ro/SSA antibodies, anti-La/SSB antibodies, and other autoantibodies to the fetus through the placenta. Usually, with the disappearance of autoantibodies in the children's body, abnormal changes in the mucocutaneous, blood system, and digestive system can spontaneously subside, but the damage to various systems caused by autoantibodies may persist for a long time. This article provides a comprehensive review of the manifestations and prognosis of NLE in various systems, including mucocutaneous, blood system, circulatory system, nervous system, digestive system, respiratory system, aiming to provide reference for clinical work.

Discovery of A New Prognostic Molecular Marker NKX2-3 for Acute Myeloid Leukemia / 中山大学学报(医学科学版)

ObjectiveTo analyze the expression of molecular marker affecting the prognosis of acute myeloid leukemia （AML） patients from bioinformatics database， thus providing an experimental basis for further exploration of a novel molecular marker for the prognosis of AML. MethodsThe prognostic data of 179 AML patients from The Cancer Genome Atlas （TCGA） database were examined for differential gene analysis and survival analysis. The bone marrow samples of 74 healthy individuals （HI） and 542 de novo AML patients in the dataset GSE13159 downloaded from the Gene Expression Omnibus （GEO） database were analyzed to detect the difference in the expression levels of differential target genes. Peripheral blood and bone marrow samples were collected from 18 de novo AML patients and 20 age- and gender-matched healthy controls， and real-time fluorescent quantitative PCR was used to validate the expression levels of the differential genes in the AML patients. ResultsBioinformatics data analysis showed that the optimal cut-off value of Homo sapiens NK2 homeobox 3 （NKX2-3） calculated by R language was 0.051. Survival analysis revealed a statistically poorer overall survival in de novo AML patients with high NKX2-3 expression than in those with low NKX2-3 expression （P = 0.0036）. NKX2-3 was highly expressed in patients with de novo AML than in HI and the difference was statistically significant （P < 0.001）. Real-time fluorescence quantitative PCR verified the expression levels of the NKX2-3 gene in AML patients and confirmed that compared with those in HI， in the de novo AML patients， NKX2-3-1 and NKX2-3-2 were highly expressed and were significantly correlated （P = 0.000， P = 0.000）. ConclusionNKX2-3 is highly expressed in de novo AML patients， and the AML patients with high NKX2-3 expression have poor overal survival. NKX2-3 may be closely related to the clinical outcome and prognosis of AML.
