ABSTRACT

BACKGROUND: Some evidence about the role of the androgen receptor (AR) in pathogenesis of glioblastoma have been reported, but no study has focused on measuring the activity of the AR in GB. Therefore, the aim of this work is to study the role of AR and its activity as prognostic biomarkers in glioblastoma (GB).

METHODS: Molecular and clinical data from The Cancer Genome Atlas database were used. The AR-expression at protein-level was obtained from reversed phase protein array (RPPA) assays. The AR-activity was determined by calculating the AR-score, an index calculated by using the expression (at RNA-level) of 13 androgen-responsive-genes. Univariate and multivariate Cox-regression analyses were performed. Finally, a correlation analysis was conducted between protein expression data and the AR-score.

RESULTS: Two-hundred and thirty-three patients were included. RPPA data showed a mean AR abundance of 0.027(Statistical Deviation = 0.38) in GB. The univariate Cox-regression analysis showed that the AR-Score was associated with a worse prognosis (Hazard Ratio (HR) = 1.070) while the AR-expression did not show any relationship with survival (HR = 0.869). The association of the AR-score with worse overall survival (OS) was still significant in the multivariate analysis (HR = 1.054). The highest correlation coefficients between the AR-score and RPPA were identified in a group of proteins involved in apoptotic process regulation.

CONCLUSIONS: GB patients with a high AR-activity present a worse prognosis in terms of OS. Thus, the activity of the AR may have a pathogenic role in GB. In this regard, the activation of the AR in GB may be associated with a dysregulation of apoptosis.

ABSTRACT

BACKGROUND: Sleep disturbance is one of the most common non-motor symptoms of Parkinson’s disease (PD). However, the confounding effects of dopaminergic medication on sleep are a major challenge in understanding the impact of sleep disturbance in PD. We investigated the sleep disturbance and associated clinical features in patients with de novo, untreated PD.

METHODS: One-hundred-eight patients with de novo, untreated PD were included. Night sleep disturbance was evaluated using the night sleep subscale of the Scales for Outcomes in Parkinson’s Disease (SCOPA-Sleep). Depression, anxiety, and apathy were assessed using the Geriatric Depression Scale (GDS), Beck Anxiety Inventory (BAI), and Apathy Evaluation Scale (AES), respectively. Early perfusion and dopamine transporter imaging of F-18 FP-CIT PET/CT were performed together with statistical parametric mapping analysis.

RESULTS: The night sleep SCOPA-Sleep sub-score was correlated with the AES (p = 0.014), BAI (p = 0.014), and GDS (p = 0.023) scores. Patients with poor night sleep were more apathetic (p = 0.013). Additionally, there was increased perfusion in the left posterior cingulate in patients with sleep disturbance and apathy compared to those with sleep disturbance only.

CONCLUSIONS: Night sleep disturbance was related to mood disorders, particularly apathy, in patients with de novo, untreated PD.

ABSTRACT

AIM: This study aimed to assess patient-safety principles in ICUs.

DESIGN: This is a descriptive-comparative study.

METHODS: The research environment includes ICUs of hospitals affiliated to the two universities of medical sciences in Tehran. Sampling was done by census using Time and Event Sampling methods. Research instrument was “Patient Safety Principles Checklist”. Data analysis was performed using SPSS-20 and descriptive-inferential statistics with a significance level of 0.05.

RESULTS: There is no significant difference (p-value = .15) in the level of observance of patient-safety principles in two university-affiliated hospitals A (133.26 ± 9.14) and B (128.16 ± 18.01). Evaluation of the mean scores obtained in each dimension and in each of the ICUs was showed that only in dimension No.3 the difference was significant (F[68,2] = 5.20, p-value = .008) and in the AICUs (16.13 ± 1.8) (p-value = .04), it was significantly lower than other ICUs. Identifying risk factors for the patient’s immunity reduces the side effects of patient care.

ABSTRACT

Aim To analyse biochemical markers as possible predictors of death before discharge in cooled newborns following perinatal asphyxia. Methods A total of 91 infants that underwent therapeutic hypothermia after perinatal asphyxia were included. Inclusion criteria for therapeutic hypothermia were Sarnat stage 2 or 3. Data were collected from medical histories regarding gender, gestational age, birth weight, Apgar and Sarnat score; additionally, gas analyses, liver and cardiac enzymes before, and in the first 12 hours after starting therapeutic hypothermia, were evaluated. The patients’ characteristics were compared between two groups, survivors and non-survivors. Results Statistical difference was not found between groups regarding gender, gestational age, birth weight, delivery type, 1st and 5th minute Apgar score, seizures, alanine aminotransferase (ALT), creatine kinase (CK), troponin and fibrinogen level. Groups were significantly different regarding acid-base balance (p=0.012), base excess (BE) (p=0.025), lactate (p=0.002), aspartate aminotransferaze (AST), (p=0.011), lactate dehydrogenase (LDH) (p=0.006), activated partial thromboplastin clotting time (aPTT) (p=0.001) and international normalized ratio (INR) (p=0.001). Conclusion Acid-base balance, BE, lactate, AST, LDH, aPTT and INR were significantly higher in the group of cooled newborns after perinatal asphyxia (non-survivors), and can serve as predictors of death before discharge. Combining diagnostic modalities raises a chance for accurate prediction of outcomes of asphyxiated infants.

ABSTRACT

Aim To determine the value of IFN (intzerferon)-α in the patients with systemic lupus erythematosus (SLE) and to correlate IFN-α with values of non-specific biochemical parameters of inflammation (C-reactive protein, leukocytes values, erythrocyte sedimentation rate, albumins and globulins). Methods Research included 55 patients with SLE diagnosis and a control group consisted of 25 healthy subjects (during period 2019-2020). IFN (Interferon)-α and non-specific biochemical parameters of inflammation were obtained using standard protocols. Results IFN-α values were independent of gender (p=0.95). The difference in serum IFN-α values in relation with the age in the SLE group was statistically significant (p=0.036). Only serum globulin was significantly higher (p=0.0023) in IFN-α positive compared to IFN-α negative SLE patients. A statistically significant correlation between the values of IFN-α and globulin was proved (r=0.315; p=0.019). No significant correlation was found between other non-specific biochemical parameters and IFN-α values. Conclusion Increased IFN-α values were observed in younger patients, and the correlation between IFN and globulin was proved.

ABSTRACT

Aim To evaluate the efficacy (rate of recanalization) of therapy with novel oral anticoagulants (NOAC; rivaroxaban, apixaban) compared to conventional treatment (low molecular weight heparin – LMWH and vitamin K antagonist) in the treatment of deep vein thrombosis (DVT) of the proximal segments of lower extremities. Methods The first group consisted of patients diagnosed with DVT and treated with NOAC (n = 100), while the second group consisted of patients diagnosed with DVT, who were treated by conventional treatment (low molecular weight heparin and vitamin K antagonists) (n = 100). In the first group, NOAC was included in the initial treatment. Patients in the second group were treated with LMWH for four days, and on the fifth day vitamin K antagonist was included in therapy, international ratio (INR) was titrated to therapeutic values (2.0-3.0), and then low molecular weight heparin was excluded from the therapy. Results There was a statistically significant difference in the estimated values of free lumen of the blood vessel between the examined groups after 30 days (p=0.0001), after 90 days (p=0.0001) and after 180 days (p=0.0001). After 180 days, the average free lumen values in the NOAC group were 85% (81-89%), which was significantly higher than the free lumen values in the second group, 73% (69-79%). Conclusion The use of NOAC represents more efficient treatment of DVT comparing to vitamin K antagonists.

ABSTRACT

Aim To investigate infl uence of neutrophil-to-lymphocyte ratio (NLR) and proatherogenic risk factors to improve the accuracy of pneumonia severity index (PSI) in the prediction of community acquired pneumonia (CAP) outcome in healthy individuals. Methods A retrospective observational cross-sectional study conducted at the Clinic for Pulmonary Diseases and Tuberculosis “Podhrastovi”, University Clinical Centre Sarajevo, included 83 patients with the diagnosis of CAP during the period March 2019-March 2021. Once diagnosed with CAP, PSI score was calculated and according to its value the need for hospital treatment was identifi ed. Patients were divided in two groups: low risk of CAP (PSI <90), and high risk of CAP (PSI> 90). Results The overall average hospital stay was 22.76±10.154 days. In the patients diagnosed with CAP, a positive correlation was established between the following parameters PSI score and age (r=0.670; p<0.01), C-reactive protein-CRP (rho=0.287; p<0.01), leukocytes (rho=0.406; p<0.01), NLR (rho=0.313; p<0.01) and platelet to lymphocyte ratio (PLR) (0.296; p<0.05). CRP, leukocytes, NLR and PLR were statistically signifi cantly higher in patients with high risk of CAP compared to patients with low risk of CAP. Diastolic blood pressure, lymphocytes, eosinophils were signifi cantly lower in patients with high risk of CAP (p<0.05;) compared to patients with low risk of CAP (p<0.01). The optimal cut-off value of NLR for CAP patients was 3.089 with an estimated area under curve (AUC) of 0.664. Conclusion Proatherogenic parameters such as age, systolic blood pressure and leukocytes in combination with neutrophil-lymphocyte count ratio could improve accuracy of the pneumonia severity index in community acquired pneumonia outcome.

ABSTRACT

WHAT IS KNOWN AND OBJECTIVE: Augmented renal clearance is prevalent in trauma patients and leads to subtherapeutic levels of renally eliminated medications with potentially unfavourable clinical outcomes. The Augmented Renal Clearance of Trauma in Intensive Care (ARCTIC) score has been developed to predict augmented renal clearance in critically ill trauma patients. Our primary objective was to validate this score among the trauma subgroup of a mixed intensive care patient cohort.

METHODS: This single-centre, retrospective, observational cohort study assessed augmented renal clearance using a timed 24-h urine collection performed weekly. ARC was defined as a measured creatinine clearance of ≥130 ml/min/1.73 m² . ARCTIC score performance was evaluated through a receiver operator characteristic curves and analysis of sensitivities and specificities for the trauma subgroup, the medical/surgical subgroup and the pooled cohort.

RESULTS AND DISCUSSION: Augmented renal clearance was observed in 33.9% (n = 58) of trauma patients (n = 171) and 15.7% (n = 24) of medical/surgical patients (n = 153). Examination of different cutoffs for the ARCTIC score in our trauma population confirmed that the optimal cutoff score was ≥6. Comparison between ROC curves for ARCTIC score and for regression model based upon our data in trauma patients indicated validation of the score in this subgroup. Comparison of sensitivities and specificities for ARCTIC score between trauma (93.1% and 41.6%, respectively) and medical/surgical subjects (87.5% and 49.6%, respectively) showed no clinical nor statistical difference, suggesting validation for the medical/surgical subgroup as well.

WHAT IS NEW AND CONCLUSION: In our mixed ICU population, the ARCTIC score was validated in the trauma subgroup. We also found that the score performed well in the medical/surgical population. Future studies should assess the performance of the ARCTIC score prospectively.

ABSTRACT

OBJECTIVE: To explore whether modified Chevron osteotomy together with distal soft tissue release would correct moderate to severe HV deformity and what is the minimal clinical important difference (MCID) for objective and subjective evaluating parameters.

METHODS: From March 2018 to January 2019, 40 hallux valgus patients (including moderate to severe) were enrolled in this retrospective study. The cohort included four males and 36 females. The average age at surgery was 50.95 (range 22-75) years. All patients underwent modified Chevron osteotomy together with distal soft tissue release and completed at least one follow-up at clinic. The American Orthopaedic Foot and Ankle forefoot score (AOFAS, forefoot), Visual Analog Scale (VAS), and Foot Function Index (FFI) were all collected before and after surgery. Besides, the hallux valgus angle (HVA), 1st-2nd intermetatarsal angle (IMA) and distal metatarsal articular angle (DMAA) were measured both before surgery and at last follow-up. All MCID values were calculated by employing distribution-based method.

RESULTS: Thirty-seven patients (92.5%) showed satisfied result at a mean 14.3-month follow-up (range 13-22 month). Two patients complained about residual pain at the bunion, and overcorrection (hallux varus) occurred in one patient. Meanwhile, no patient observed nonunion. Being female, age more than 60, residual HVA deformity (>15°), and post IMA more than 9° showed no statistical relationship with the post-operation residual pain (P > 0.05). However, high VAS score before surgery (more than 7) showed strong correlation with residual pain (P < 0.01). The subjective MCID value was 9.50 for AOFAS, 18.92 for FFI, and 1.27 for VAS, respectively.

CONCLUSION: The modified Chevron osteotomy together with distal soft tissue release could achieve a satisfied result for moderate to severe HV deformity at early follow-up. The residual pain was associated with severe pain before surgery (VAS more than 7).

ABSTRACT

Approximately 80% of primary healthcare facilities in China were ready to deliver hepatitis care services by 2021. This study aimed to assess hepatitis B and C test uptake, identify the factors associated with testing, and determine the predictors of hepatitis stigma among primary care patients. We conducted a cross-sectional survey among patients seeking care in the family medicine and primary care unit of the University of Hong Kong-Shenzhen Hospital, China. Participants were 30 years or older and had not tested for HBV and HCV in the preceding 12 months. Test uptake was defined as self-reported previous HBV and HCV testing. Descriptive statistics, Chi-square test, forward multivariable logistic regression, and stepwise multiple linear regression were conducted and a p-value <0.05 was deemed statistically significant. A total of 750 eligible patients completed the survey, and 54.5% (404±0.9) were between 30~40 years old. Most participants were heterosexuals 98.0% (n=735), female 57.5% (n=431), married 78.3% (587), and earned ≤1500 USD per month 54.4% (n=408). A 66.1% (n=496) and 13.7% (n=103) self-reported previous HBV and HCV testing respectively, and 62% (n=468) were vaccinated. HCV testing was associated with HBV testing (aOR= 13.7, 95% CI:2.1~91.5); and HBV testing was associated with family history of HBV (aOR=2.4, 95%CI:1.1~5.5). Overall hepatitis stigma was about average and decreased with family history of HBV (p=0.017). In conclusion, HCV testing uptake among primary care patients was low and needs to be further promoted. Integrating HBV and HCV testing interventions and fostering family-based support for disclosure could effectively improve testing uptake.
