Indicator Of Worse Prognosis Research Articles

Survival outcomes according to the tumor location and prognostic factor in metastatic rectal cancer: a multicenter retrospective cohort study.

Prognostic factors of metastatic rectal cancer are not well known. We aim to determine prognostic factors affecting survival for metastatic rectal cancer patients and also to investigate the effect of tumor localization on overall survival. Metastatic rectal cancer patients who received treatment in 5 different centers between 2012 and 2022 were included. Prognostic factors for survival were evaluated using univariate and multivariate analysis. The statistical methods included Pearson's chi-square test, Fisher exact test, Log-rank test, and Cox regression model. A total of 283 patients with metastatic rectal cancer were included in the study. The median OS was not significantly different among the three groups (upper rectum 30.1 months, middle rectum 28.3 months, and low rectum cancer 24.8 months; log-rank p = 0.25). In univariate analysis, Grade 3, ECOG performance status 2, the presence of multiple metastatic sites, the presence of KRAS mutation, the presence of liver metastases, the presence of nonregional lymph node metastases, and the presence of bone metastases were significant predictors of poor survival. In multivariate analysis, Grade 3, ECOG performance status 2, and the presence of multiple metastatic sites were determined as indicators of worse prognosis. Our findings, primary tumor location did not affect survival in metastatic rectal cancer. The most important factors affecting survival were multiple metastatic sites, tumor grade, and ECOG performance status.

Clinical Evaluation of Hospitalized Cases of Acute Febrile Illness with Thrombocytopenia in North - West Zone of Rajasthan

Background: Thrombocytopenia has been recognized as an important manifestation of acute febrile illness caused by various types of. Early diagnosis of aetiology is very important to reduce morbidity and mortality. This study was planned to evaluate clinical profile, aetiology, differential diagnosis, clinical course and outcome of such patients. Methods: Present prospective cross-sectional study was conducted on 400 consecutive patients of fever with thrombocytopenia admitted during 1st May 2022 to 31st October 2022 in the Department of Medicine, S.P. Medical College & Associated Group of P.B.M. Hospitals, Bikaner. All patients were evaluated as per proforma including detail clinical history and physical examination. Laboratory evaluation including CBC, RFT, LFT, blood sugar, LDH, Rapid diagnostic test for malaria, PBF for MP, test for dengue, HBsAg, Anti HCV, HIV, PBF detail, Blood culture, D–dimer, test for Scrub typhus and leptospirosis, Ultrasonography and chest X-Ray was done in all cases. Other investigations were done as per requirement. All patients were treated as per guidelines and followed-up during hospitalization. Results: Out of 400 patients 227 were males (age ranging 15-87 years, mean 35.46 ±15.63) and 173 females (age ranging 15-92 years, mean 39.75 ± 17.36). Dengue fever was found to be the commonest cause (29.5%) followed by Malaria, COVID-19 infection (0.75%) and one each HIV and Hepatitis B. In 54.25% of the cases definite etiological diagnosis could not be ascertained. 14.25% patients were having life threatening thrombocytopenia, 45% severe grade, 21.75% moderate and 19% mild thrombocytopenia. Severity of thrombocytopenia was associated with longer duration of illness (p<0.02). Bleeding manifestations were observed in 5.75% but did not corelated with severity of thrombocytopenia. Mean duration of hospital stay was found to be inversely proportion to total platelet count on admission. Conclusion: Acute Febrile illness patients should be investigated for platelet count irrespective of the bleeding manifestations as decreased platelet count could be severe without external manifestations and could be an indicator of bad prognosis.

A High Copy Number from a Pharyngeal Swab Is Not Associated with Different Presenting Features in 100 Children with Acute Adenovirus Infection from a Cluster in Italy.

Human mastadenoviruses, frequently denominated adenoviruses (HAdVs), may cause respiratory tract, gastrointestinal or, less frequently, other involvements. Epidemics of HAdV infections occur globally, in communities, and in closed or crowded settings. In our institution, a cluster of infants and children admitted for HAdV infection was recently observed. The aim of this study was to describe the pattern of their presenting features and investigate the possible correlation between the HAdV copy number and the clinical picture. Two main patterns of clinical presentation were observed: 68 patients had mainly respiratory symptoms (pharyngitis n = 67, cough n = 44; tonsillar exudate n = 17; other respiratory signs n = 4) while 26 patients showed prevalent gastrointestinal involvement (diarrhea n = 26, vomiting n = 8). Patients with respiratory symptoms had a significantly higher count of WBC, PMN, and platelets, while CRP level approached statistical significance (p = 0.07) for higher values in the patients with diarrhea. In order to explore the impact of selected presenting features, the possible association between the level of CRP and the presence of pharyngeal exudate, cough, vomiting, diarrhea, duration of fever, number of neutrophils, and administration of antibiotics was analyzed. Patients falling in the tertile with more elevated CRP values had tonsillar exudate and diarrhea significantly more often, while those in the lower tertile had a 4.4-day duration fever vs. ≥5.0 days in the remaining patients. Antibiotic therapy was administered more frequently to patients with higher values of CRP (p = 0.006). The duration of hospitalization was not associated with the CRP level. The median time from the receipt of a positive HAdV PCR test result to patient discharge was 1 day in 73% of cases. The number of copies of HAdV detected via PCR ranged between 47 million and 15/μL. Falling in the highest tertile of copy number was significantly associated with pharyngitis. The 24 patients with evidence of viral coinfection had no difference in the demographics or presenting features, with the only exception being a significantly higher leukocyte count. The rapid turn-around of the results of the molecular testing of the HAdV genome on a pharyngeal swab allowed us to rapidly diagnose HAdV infection, allowing us to stop antibiotic therapy and immediately discharge the patients, with reduced discomfort for the families and more appropriate use of hospital beds. A high copy number of HAdV from a pharyngeal swab should not be taken as an indicator of worse prognosis, thus allowing for the preferential use of qualitative rather than quantitative assay.

The significance of peri-neural invasion in patients with gallbladder carcinoma after curative surgery: a 10year experience in China.

The significance of peri-neural invasion (PNI) in patients with gallbladder carcinoma (GBC) after curative surgery remains unknown. Current study was performed to evaluate the significance of PNI in resected GBC patients in terms of tumor-related biological features and long-term survival. Patients with GBC between September 2010 and September 2020 were reviewed and analyzed. SPSS 25.0 software were used for statistical analysis. A total of 324 resected GBC patients were identified (No. PNI: 64). An elevated preoperative Ca19.9 level (P = 0.001), obstructive jaundice (P = 0.001), liver invasion (P < 0.0001), lymph-vascular invasion (P < 0.0001), lymph-node metastasis (P < 0.0001), and poor or moderate differentiation status (P = 0.036) were more frequently detected in patients with PNI. Major hepatectomy (P = 0.019), bile duct resection (P < 0.0001), combined multi-visceral resections (P = 0.001), and combined major vascular resections and reconstructions (P = 0.002) were also more frequently detected. However, a significantly lower R0 rate (P < 0.0001) was acquired in patients with PNI. Patients with PNI were generally more advanced disease and shared a much worse prognosis even after matching. PNI was an independent prognostic factor of disease-free survival as well as an independent predictor of early recurrence. Postoperative adjuvant chemotherapy has brought an obvious survival benefit in resected GBC patients with PNI. PNI could be regarded as an indicator of worse prognosis and could serve as an independent predictor of early recurrence. Postoperative adjuvant chemotherapy was correlated with an improved survival for resected GBC patients with PNI. Upcoming multicenter studies covering various races are warranted for further validation.

Measurement of skeletal muscle volume is useful for predicting prognosis in patients with liver cirrhosis.

Hepatic venous pressure gradient (HVPG) and the model for end-stage liver disease (MELD) score were previously reported as prognostic factors for outcome in patients with liver cirrhosis (LC), and recently, the presence of sarcopenia was reported to be an indicator of worse prognosis in these patients. This retrospective study aimed to clarify the importance of sarcopenia as a prognostic factor in patients with LC. The MELD-Na score, HVPG, and skeletal muscle index (SMI) were measured in 202 patients between January 2013 and August 2020. We performed linear regression analysis between HVPG and SMI and calculated suitable cutoff values of HVPG for predicting presarcopenia and of HVPG, ΔSMI (i.e. the decrease in SMI per year, for predicting survival). Overall survival rates with the HVPG and ΔSMI cutoff values were compared by Kaplan-Meier estimates and log-rank tests. Prognostic factors for survival were analyzed by Cox regression univariate and multivariate analyses. In total, 71% (143/202) of patients presented with presarcopenia. Linear regression showed a significantly negative correlation between HVPG and SMI. Survival was significantly worse in the group with presarcopenia than in the group without. Survival was worse also in the group with an HVPG value ≥ 15 and ΔSMI ≥ -2.4. Cox regression multivariate analyses showed that MELD-Na score, HVPG, HVPG ≥ 15, ΔSMI, and ΔSMI ≥ -2.4 were independent prognostic factors. Skeletal muscle volume, especially ΔSMI, has a prognostic value equivalent to that of the MELD-Na score and HVPG.

Assessment of tumor extension to the ductal system of submucosal glands in patients with superficial esophageal squamous neoplasms: Implications for endoscopic resection.

Endoscopic submucosal dissection (ESD) has become the standard treatment for superficial esophageal squamous cell neoplasia (SESCN); however, local recurrence still occurs occasionally even in patients who meet the current curative criteria. Esophageal ducts of the submucosal gland may serve as a pathway for the spread of SESCN to a deeper layer. However, the clinical impact of ductal involvement (DI) in patients undergoing ESD has yet to be investigated. We consecutively enrolled patients with SESCN who were treated with ESD. The resected specimens were meticulously reviewed in multiple section slices for the presence and resected margins of DI, and their correlations with clinical factors were evaluated. A total of 210 lesions were analyzed, of which 78 (37.1%) presented with DI. The presence of submucosal invasion, lymphovascular invasion (LVI), and DI were indicators of worse prognosis (P<.05). Deep extended DIs were misdiagnosed as deep submucosal invasive cancer in 4 cases (2%). Of the 185 patients who met the criteria for curative ESD (ie, R0 resection and no deep submucosal invasion or LVI), 11 (5.9%) developed local recurrence/metastasis during a mean follow-up of 55.2months (range, 6 to 140) months. Compared with patients with without DI, patients with DI had worse recurrence-free survival (P=.008, log-rank test) and a higher local risk of recurrence (12.7% vs 2.5%) after curative ESD (hazard ratio, 4.20; P=.038). A precise histological assessment of DI in SESCN is crucial after ESD, given that DI is common and associated with worse outcome. Whether total removal of esophageal glands/ducts can improve outcome requires future study.

High frequency of PDGFRA and MUC family gene mutations in diffuse hemispheric glioma, H3 G34-mutant: a glimmer of hope?

BackgroundDiffuse hemispheric glioma H3 G34-mutant (G34-DHG) is a new type of pediatric-type diffuse high-grade glioma in the fifth edition of the WHO Classification of Tumors of the Central Nervous System. The current treatment for G34-DHG involves a combination of surgery and conventional radiotherapy or chemotherapy; however, the therapeutic efficacy of this approach is not satisfactory. In recent years, molecular targeted therapy and immunotherapy have achieved significant benefits in a variety of tumors. In-depth understanding of molecular changes and immune infiltration in G34-DHGs will help to establish personalized tumor treatment strategies. Here, we report the clinicopathological, molecular and immune infiltration characteristics of G34-DHG cases from our center along with cases from the HERBY Trial and the Chinese Glioma Genome Atlas database (CGGA).MethodsHematoxylin–eosin (HE) and immunohistochemistry (IHC) staining were used to present the clinicopathological characteristics of 10 Chinese G34-DHG patients treated at our institution. To address the molecular characteristics of G34-DHG, we performed whole-exome sequencing (WES) and RNA sequencing (RNA-seq) analyses of 5 patients from our center and 3 Chinese patients from the Chinese Glioma Genome Atlas (CGGA) database. Additionally, 7 European G34-DHG patients from the HERBY Trail were also subjected to analyses, with 7 cases of WES data and 2 cases of RNA-seq data. Six G34-DHG patients from another organization were used as external validation.ResultsWES showed a high frequency of PDGFRA mutation in G34-DHGs (12/15). We further identified frequent mutations in MUC family genes in G34-DHGs, including MUC16 (8/15) and MUC17 (8/15). Although no statistical difference was found, PDGFRA mutation tended to be an indicator for worse prognosis whereas MUC16/MUC17 mutation indicated a favorable prognosis in G34-DHGs. RNA sequencing results revealed that most G34-DHG are considered to be immune cold tumors. However, one patient in our cohort with MUC16 mutation showed significant immune infiltration, and the total overall survival of this patient reached 75 months.ConclusionsOur results demonstrate that G34-DHG is a new high-grade glioma with high frequency of PDGFRA and MUC gene family mutations. PDGFRA may serve as an indicator of poor prognosis and an effective therapeutic target. Moreover, MUC16 tends to be a favorable prognostic factor and indicates high immune infiltration in certain patients, and these findings may provide a new direction for targeted therapy and immunotherapy of patients with G34-DHGs.

Exploring CT Texture Parameters as Predictive and Response Imaging Biomarkers of Survival in Patients With Metastatic Melanoma Treated With PD-1 Inhibitor Nivolumab: A Pilot Study Using a Delta-Radiomics Approach.

In the era of artificial intelligence and precision medicine, the use of quantitative imaging methodological approaches could improve the cancer patient’s therapeutic approaches. Specifically, our pilot study aims to explore whether CT texture features on both baseline and first post-treatment contrast-enhanced CT may act as a predictor of overall survival (OS) and progression-free survival (PFS) in metastatic melanoma (MM) patients treated with the PD-1 inhibitor Nivolumab. Ninety-four lesions from 32 patients treated with Nivolumab were analyzed. Manual segmentation was performed using a free-hand polygon approach by drawing a region of interest (ROI) around each target lesion (up to five lesions were selected per patient according to RECIST 1.1). Filtration-histogram-based texture analysis was employed using a commercially available research software called TexRAD (Feedback Medical Ltd, London, UK; https://fbkmed.com/texrad-landing-2/) Percentage changes in texture features were calculated to perform delta-radiomics analysis. Texture feature kurtosis at fine and medium filter scale predicted OS and PFS. A higher kurtosis is correlated with good prognosis; kurtosis values greater than 1.11 for SSF = 2 and 1.20 for SSF = 3 were indicators of higher OS (fine texture: 192 HR = 0.56, 95% CI = 0.32–0.96, p = 0.03; medium texture: HR = 0.54, 95% CI = 0.29–0.99, p = 0.04) and PFS (fine texture: HR = 0.53, 95% CI = 0.29–0.95, p = 0.03; medium texture: HR = 0.49, 209 95% CI = 0.25–0.96, p = 0.03). In delta-radiomics analysis, the entropy percentage variation correlated with OS and PFS. Increasing entropy indicates a worse outcome. An entropy variation greater than 5% was an indicator of bad prognosis. CT delta-texture analysis quantified as entropy predicted OS and PFS. Baseline CT texture quantified as kurtosis also predicted survival baseline. Further studies with larger cohorts are mandatory to confirm these promising exploratory results.

Metabolic, Affective and Neurocognitive Characterization of Metabolic Syndrome Patients with and without Food Addiction. Implications for Weight Progression.

According to the food addiction (FA) model, the consumption of certain types of food could be potentially addictive and can lead to changes in intake regulation. We aimed to describe metabolic parameters, dietary characteristics, and affective and neurocognitive vulnerabilities of individuals with and without FA, and to explore its influences on weight loss progression. The sample included 448 adults (55–75 years) with overweight/obesity and metabolic syndrome from the PREDIMED-Plus cognition sub-study. Cognitive and psychopathological assessments, as well as dietary, biochemical, and metabolic measurements, were assessed at baseline. Weight progression was evaluated after a 3-year follow up. The presence of FA was associated with higher depressive symptomatology, neurocognitive decline, low quality of life, high body mass index (BMI), and high waist circumference, but not with metabolic comorbidities. No differences were observed in the dietary characteristics except for the saturated and monounsaturated fatty acids consumption. After three years, the presence of FA at baseline resulted in a significantly higher weight regain. FA is associated with worse psychological and neurocognitive state and higher weight regain in adults with metabolic syndrome. This condition could be an indicator of bad prognosis in the search for a successful weight loss process.

Ping-pong gaze in a refractory focal status epilepticus

An 83-year-old woman presented to emergency department with fever, low level of consciousness and right deviation in the conjugate gaze. Neurological examination revealed a spontaneous, slow, horizontal and continuous conjugate eye deviation alternating every 2 to 3 seconds. An electroencephalogram revealed periodic paroxysmal activity with a frequency of 2-3 Hz in left frontal hemispheric. Neuroimaging didn’t show pathological findings. Polymorphonuclear leukocytes were observed in CSF without evidence of microorganisms. Antiepileptic therapy was started without improvement. Finally, the patient died because of refractory focal status. Ping Pong Gaze (PPG) is a slow and rhythmical horizontal abnormal eye movement with a fixed frequency that is observed in comatose states and indicates diffuse structural brain lesions with preserved brainstem functions. PPG presence is an indicator of bad prognosis. We describe a PPG case with a synchronous eye movement with the electroencephalogram activity. Keywords: Ping-pong gaze; status epilepticus; electroencephalography; epilepsy; seizure.

Loss of p21ras, p53, and Mdm2 Protein Expression Is Indicative of Worse Prognosis in Myelodysplastic Syndromes.

Myelodysplastic syndromes (MDS) comprise a group of clonal disorders of the hematopoietic stem cell characterized by ineffective hematopoiesis and refractory cytopenias that can progress to acute leukemia. In order to identify molecular events implicated in the pathogenesis of MDS, we analyzed the bone marrow expression and mutational status of ras, p53 and mdm2 genes in a cohort of 25 patients with MDS. The expression of p21ras, p53, and Mdm2 proteins was studied in marrow cytopins stained by APAAP (alkaline phosphatase anti-alkaline phosphatase procedure) using monoclonal antibodies Y13-219, PAb 1801 and 2A10 to detect p21ras, p53 and mdm2 proteins, respectively. N-, K-, H-ras and p53 gene mutations were assessed by PCR-SSCP (polymerase chain reaction/single strand conformation polymorphism) and DNA sequencing to exclude the presence of gene mutations. The quantitative wild-type expression of p21ras, p53 and mdm2 proteins in patient samples (combination of number of cells and staining intensity) was compared to the values of expression of these proteins in 7 normal bone marrow samples. We found overexpression of p21ras and p53 proteins in 12/22 (55%) and 7/23 (30%) of the patients. Five of 7 patients who overexpressed wt-p53 also co-overexpressed wt-p21ras protein. We observed absence of expression of p21ras, p53 and mdm2 in 4/22, 4/23 and 9/19 cases, respectively. Overall survival of patients with absence of p21ras and p53 expression was considerably worse than that of patients with normal expression of these proteins (p=0.0006 to p21ras and p=0.004 to p53 by Log-Rank test; p=0.02 to p21ras and p=0.01 to p53 by Cox proportional hazards model after age, neutrophil and platelet count, and hemoglobin adjustment). We also observed that the patients who exhibited hypoexpression (p=0.055) and absence of mdm2 expression (p=0.07) demonstrated a tendency to have worse prognosis (Log-Rank). There was no correlation between variables p21ras, p53 and mdm2 versus hemoglobin, platelet and neutrophil counts and no association between FAB SMD subcategories and absence of p53 and mdm2 expression by Fisher test (two-tailed), but there was a strong over-representation between absence of p21ras expression and MDS with excess of blasts (p=0.0006). There was a significant correlation between p53 and mdm2 gene expression (p=0.03, Pearson). Only one patient harbored one transversion mutation in codon 12 of K-ras gene and did not correlate with p53 overexpression, but with worse prognosis. No p53 mutation was found. Overall, these findings suggest that the via of signal transduction p21ras/p53 and the auto-regulatory genes p53/mdm2 may be active and play a pivotal role in the pathogenesis of MDS. Hence, loss of bone marrow expression of p21ras, p53 and/or mdm2 proteins is an indicator of worse prognosis in MDS and may serve as early markers of leukemic transformation.

Sustained ventricular tachycardia in cardiogenic shock

Abstract Funding Acknowledgements Type of funding sources: None. Introduction Cardiogenic shock (CS) and the presence of sustained ventricular tachycardia (VT) are indicators of worse prognosis in hospitalized patients. In patients severely ill, like patients with CS, the registration of VT can be a stressful situation as well a life threatening condition. Purpose Evaluate the impact of cardiovascular previous history, clinical signs and diagnosis procedures at admission as predictors of VT in CS patients. Methods Single-centre retrospective study, engaging patients hospitalized for CS between 1/01/2014-30/10/2018. 222 patients with CS are included, 19 of them presented VT. Chi-square test, T-student test and Mann-Whitney U test were used to compare categorical and continuous variables. Multiple linear regression analysis was performed to evaluate predictors of new-onset AF in CS patients. Results CS patients without VT and with VT presented similar age, sex, cardiovascular history (namely arterial hypertension, diabetes, dyslipidemia, obesity, smoker status, alcohol intake, previous acute coronary syndrome, history of angina, previous cardiomyopathy), neoplasia history, cardiac arrest during the CS, clinical signs at admission (like heart rate, blood pressure, respiratory rate), blood results (hemoglobin, leucocytes, troponin, creatinine, C-Reactive protein), left ventricular ejection fraction and the culprit lesion. Curiously, history of previous stroke was higher in the group of VT in CS patients with a 6.9% (p = 0.021). Curiously, VT in CS patient had not impact in mortality rates. Multiple logistic regression reveals that previous stroke was a predictor of VT in CS patients (odds ratio 4.337, confident interval 1.363-13.799, p = 0.013). Conclusions History of previous stroke was a predictor of sustained VT in CS patients. The presence of this ventricular arrhythmia can have a hemodynamic impact, however, seems not influenced mortality rates.

Increased Expression of Type-I Collagen in Malignant Colorectal Lesion and Positive Correlations with Clinical Factors

Abstract Objective Type-I collagen (Col-I) is one of the main macromolecules of the extracellular matrix, and it is involved in the desmoplastic stromal reaction, an indicator of worse prognosis in cases of colorectal cancer (CRC). The purpose of the present study was to investigate Col-I expression in cases of CRC and adenoma and to correlate with the clinical data and the data regarding the lifestyle of the patients. Methods A retrospective study including 22 patients with adenoma and 15 with CRC treated at a coloproctology service. The clinical and lifestyle data were obtained through medical records, and Col-I expression was investigated by immunohistochemistry. Results Women represented most cases of adenoma (63.64%), whereas CRC was found mainly in men (73.33%) (p = 0.0448). Immunoexpression of Col-I showed a basement membrane thickening in areas of lining of epithelium and around the glands in both lesions. The cases of CRC had a quite evident fibrosis process in the stroma. The quantitative analysis demonstrated a higher protein expression in CRCs compared to adenomas (p = 0.0109), as well as in female patients (p = 0.0214), patients aged ≥ 50 years (p = 0.0400), and in those with a positive family history of colorectal disease (p = 0.0292). These results suggested a remodeling of the microenvironment of the tumor in CRC carcinogenesis. Importantly, the clinicopathologic positive correlations showed a plausible link between the patient's profile and the immunohistochemical findings, which indicate a possible form of patient stratification. Conclusion The immunohistochemical analysis encourages the performance of more comprehensive studies to ascertain if our results could be a tool for the diagnosis and monitoring of the patients.

Prognostic implication and functional exploration for microRNA-20a as a molecular biomarker of gastrointestinal cancer

BackgroundIt is generally accepted that microRNA-20a (miR-20a) is aberrantly expressed in gastrointestinal cancer (GIC), and may be associated with the prognosis of GIC patients. Nevertheless, the clinical prognostic value of miR-20a expression in GIC remains controversial.MethodsWe first conducted a comprehensive literature search of the clinical data and pooled them for evidence in assessing prognostic significance of miR-20a expression in GIC. Afterwards, we applied some bioinformatic analysis methods to explore the biological function of miR-20a and explain why miR-20a could act as an effective biomarker.ResultsThe pooled results showed that enhanced miR-20a expression was significantly associated with poor survival in GIC patients (HR: 1.36; 95%CI: 1.21–1.52; P < 0.001). According to the subgroup analysis, the ethnicity, cancer type, sample source, and sample size may have an impact on the predictive roles for miR-20a. The gene ontologies enriched by the predicted miR-20a targets were highly associated with some important biological processes, cell components and molecular functions. Moreover, a series of prominent pathways linked with GIC carcinogenesis were identified. Ultimately, the crucial targets and modules were identified by constructing the protein-protein interaction network of miR-20a targets, which were highly associated with the initiation and progression of GIC according to previous molecular biology experiments.ConclusionsOur results indicated that high expression of miR-20a may be a credible indicator of worse prognosis in GIC. Further studies involving biological experiments and larger sample sizes should be performed to validate these findings.

Comparison of schizophrenia outpatients in residential care facilities with those living with someone: Study of mental and physical health, cognitive functioning, and biomarkers of aging

This paper aims to compare mental and physical health, cognitive functioning, and selected biomarkers of aging reflecting metabolic pathology and inflammation, in outpatients with schizophrenia from two residential settings: residential care facilities (RCFs) and living with someone in a house/apartment. This cross-sectional study examined community-dwelling adults with schizophrenia either in RCFs (N = 100) or in a house/apartment with someone (N = 76), recruited for two NIH-funded studies in San Diego. Assessments included measures of mental/physical health, cognitive function, and metabolic (glycosylated hemoglobin, cholesterol) and inflammatory (C-Reactive Protein, Tumor Necrosis Factor-alpha, Interleukin-6) biomarkers of aging. General logistic models were used to analyze factors associated with residential status.RCF residents had several indicators of worse prognosis (never being married, higher daily antipsychotic dosages, increased comorbidities and higher Framingham risk for coronary heart disease) than individuals living with someone. However, RCF residents had better mental well-being and lower BMI, as well as comparable biomarkers of aging as those living with someone. While the cross-sectional nature of the study does not allow us to infer causality, it is possible that the supportive environment of RCFs may have a positive impact on mental and physical health of persons with schizophrenia. Longitudinal follow-up studies are needed to test this hypothesis.

Demographic profile and ocular characteristics of stage 5 retinopathy of prematurity at a referral center in Northwest China: implications for implementation

BackgroundSevere retinopathy of prematurity (ROP) with extremely unfavorable prognosis among infants can do great damage to individuals and bring tremendous social-economic burden. The purpose of this study is to describe the demographic and ocular characteristics of infants who presented with stage 5 ROP in order to identify reasons why they have become blind, and to identify contributing factors in order to focus great attention on the current ROP program and to inspire more effort in ROP screening in middle income countries.MethodsA retrospective review of consecutive infants with stage 5 ROP from December 2010 to December 2016 in Department of Ophthalmology, Xijing Hospital. Various parameters retrieved included birthweight, gestational age, age at initial examination, postmenstrual age, screening details, check-up details and reasons for consultation. Ocular findings were recorded and also detected by ultrasonography.ResultsA retrospective review of 20 consecutive infants with stage 5 ROP are included. Mean birthweight was1712.3 ± 512.97 g and mean gestational age at birth was 32.1 ± 2.21 weeks. Median age at first consultancy was 9.7 month. Median postmenstrual age first consultancy was 52 weeks. All infants were never screened for ROP before they came to the referral center. Of twenty stage 5 ROP infants, 13 cases presented with bilateral stage 5 features. Of the 40 eyes of 20 infants, 33 eyes were diagnosed as stage 5. Leukocoric pupil, closed funnel configuration of retinal detachment (RD), posterior synechia, extraretinal fibrovascular proliferation and retinal folds were the most significant indicators of bad prognosis. Ten eyes appeared no fixation to light, while 30 eyes exhibited following to light or following to toys.ConclusionsOur study shows that in relatively less-developed regions of China, more needs to be done to spread awareness about the disease among pediatricians, neonatologists and ophthalmologists as well as parents of premature infants. Thus, a comprehensive control system which is a whole network of propaganda, screening, treatment and follow-up are encouraged especially in less developed areas in China as well as worldwide.

The prognostic value of long noncoding RNA ZEB1-AS1 on clinical outcomes in human cancer.

Background: Although growing evidence have demonstrated that long non-coding RNA ZEB1-AS1 was aberrantly expressed in various types of cancers and can be used as a prognostic marker in cancer, the results remain inconclusive. Therefore, we performed this meta-analysis to evaluate the prognostic value of ZEB1-AS1 in human cancer.Methods: A literature survey was conducted for all eligible studies by searching the following online databases: PubMed and Embase. The pooled odds ratios (ORs) or hazard ratios (HRs) with a 95 % confidence interval (95 % Cl) were computed to demonstrate its prognostic value.Results: A total of 14 studies with 1096 individuals were included to evaluate the association of ZEB1-AS1 with clinicopathological features and overall survival (OS). In the pooled analyses stratified by clinicopathological features, ZEB1-AS1 expression was significantly related to depth of tumor (OR=2.92, 95% CI 1.22-7.02), poor histological differentiation (OR=2.72, 95% CI: 1.92-3.86), lymph node metastasis (OR=3.93, 95% CI: 2.65-5.84), distant metastasis (OR=5.34, 95% CI: 2.85-10.02) and tumor stage (OR=2.46, 95% CI 1.42-4.24), but not to tumor size (OR=1.25, 95% CI 0.79-1.96). Altered ZEB1-AS1 expression was found to be an indicator of worse prognosis in OS (HR = 1.94, 95% CI: 1. 66-2.22) among tumor patients.Conclusions: High ZEB1-AS1expression was associated poor clinical outcome and it can serve as a novel predictive biomarker in various cancers.

A retrospective comparison of survivors and non-survivors of massive pulmonary embolism receiving veno-arterial extracorporeal membrane oxygenation support

IntroductionWhile the optimal care of patients with massive pulmonary embolism (PE) is unclear, the general goal of therapy is to rapidly correct the physiologic derangements propagated by obstructive clot. Extracorporeal membrane oxygenation (ECMO) in this setting is promising, however the paucity of data limits its routine use. Our institution expanded the role of ECMO as an advanced therapy option in the initial management of massive PE. The purpose of this project was to evaluate ECMO-treated patients with massive PE at an academic medical center and report shortterm mortality outcomes. MethodsThirty-two patients placed on ECMO for confirmed, massive PE from January 2012 to December 2015 were retrospectively analyzed. All patients had PE confirmed by computerized tomography and/or invasive pulmonary angiography. ResultsIn our population of patients managed with ECMO, 21 (65.6%) patients survived to decannulation and 17 (53.1%) survived index hospitalization. Baseline characteristics and clinical variables showed no difference in age, gender, right ventricular-to-left ventricular ratios, or peak troponin-T between survivors and non-survivors. Non-survivors tended to have a previous history of malignancy. Cardiac arrest prior to ECMO cannulation was associated with worse outcomes. All 5 patients who received concomitant systemic thrombolysis died, while 11 of 15 patients who received catheter-directed thrombolysis survived. A lactic acid level ≤6mmol/L had an 82.4% sensitivity and 84.6% specificity for predicting survival to discharge. ConclusionThe practical approach of utilizing ECMO for massive PE is to reserve it for those who would receive the greatest benefit. Patients with poor perfusion, for example from cardiac arrest, may gain less benefit from ECMO. Our findings indicate that a serum lactate >6mmol/L may be an indicator of worse prognosis. Finally, in our patient population, catheter-directed thrombolytics was effectively combined with ECMO.

CT‐determined pulmonary artery to aorta ratio as a predictor of elevated pulmonary artery pressure and survival in idiopathic pulmonary fibrosis

Elevated mean pulmonary artery pressure (mPAP) is a significant prognostic indicator in idiopathic pulmonary fibrosis (IPF). It has been reported that the computed tomography-determined ratio of the diameter of the pulmonary artery to the aorta (PA:A) is correlated with mPAP in various respiratory diseases. However, in patients with IPF, whether the PA:A can be used to predict elevated mPAP and the prognostic value of the PA:A has not been fully evaluated. We conducted a single-centre, observational study of 177 consecutive IPF patients who underwent right heart catheterization. We examined the association between the PA:A and mPAP in these patients, and performed a receiver operating characteristic (ROC) analysis to test the diagnostic accuracy of the PA:A in predicting mPAP > 20 mm Hg (pulmonary hypertension (PH) or borderline PH) in relation to survival. In a multivariate linear regression analysis, the PA:A, 6-min walk distance and diffusion capacity for carbon monoxide (DLCO ) % predicted were independent explanatory variables of elevated mPAP (P < 0.0001, P = 0.009 and P = 0.002, respectively). ROC analysis revealed a PA:A > 0.9 to be optimal for predicting mPAP > 20 mmHg (area under the curve (AUC) = 0.75; 95% CI: 0.65-0.84). Patients with a PA:A > 0.9 also had a worse prognosis (P = 0.009). Measurement of the PA:A is a useful and convenient method to predict elevated mPAP in IPF at initial evaluation. Moreover, a PA:A >0.9 was found to be an indicator of worse prognosis.
