High S100B Levels Predict Antidepressant Response in Patients With Major Depression Even When Considering Inflammatory and Metabolic Markers

BackgroundThe relationship between antidepressant response and glial, inflammatory, and metabolic markers is poorly understood in depression. This study assessed the ability of biological markers to predict antidepressant response in major depressive disorder (MDD).MethodsWe included 31 MDD outpatients treated with escitalopram or sertraline for 8 consecutive weeks. The Montgomery-Åsberg Depression Rating Scale (MADRS) was administered at baseline and at week 4 and 8 of treatment. Concomitantly, blood samples were collected for the determination of serum S100B, C-reactive protein (CRP), and high-density lipoprotein cholesterol (HDL)-C levels. Treatment response was defined as ≥50% improvement in the MADRS score from baseline to either week 4 or 8. Variables associated with treatment response were included in a linear regression model as predictors of treatment response.ResultsTwenty-seven patients (87%) completed 8 weeks of treatment; 74% and 63% were responders at week 4 and 8, respectively. High S100B and low HDL-C levels at baseline were associated with better treatment response at both time points. Low CRP levels were correlated with better response at week 4. Multivariate analysis showed that high baseline S100B levels and low baseline HDL-C levels were good predictors of treatment response at week 4 (R^2 =0.457, P = .001), while S100B was at week 8 (R² = 0.239, P = .011). Importantly, baseline S100B and HDL-C levels were not associated with depression severity and did not change over time with clinical improvement.ConclusionsSerum S100B levels appear to be a useful biomarker of antidepressant response in MDD even when considering inflammatory and metabolic markers.     

Extracorporeal membrane oxygenation support in carinal resection for recurrent chondrosarcoma after previous distal tracheal resection

Carinal re-resection for tumour recurrence is rarely performed due to increased difficulty in airway reconstruction. We reported a successful case of carinal resection and reconstruction for recurrent chondrosarcoma after previous distal tracheal resection. Due to the technical complexity of the reconstruction and the poor respiratory reserve of the patient, the veno-venous extracorporeal membrane oxygenation support was used.     

Contemporary outcomes of cardiac surgery patients supported by the intra-aortic balloon pump

Open in a separate window OBJECTIVESAlthough the intra-aortic balloon pump (IABP) has been the most widely adopted temporary mechanical support device in cardiac surgical patients, its use has declined. The current study aimed to evaluate the occurrence and predictors of early mortality and complication rates in contemporary cardiac surgery patients supported by an IABP.METHODSA multicentre, retrospective analysis was performed of all consecutive cardiac surgical patients receiving perioperative balloon pump support in 8 centres between January 2010 to December 2019. The primary outcome was early mortality, and secondary outcomes were balloon-associated complications. A multivariable binary logistic regression model was applied to evaluate predictors of the primary outcome.RESULTSThe study cohort consisted of 2615 consecutive patients. The median age was 68 years [25th percentile 61, 75th percentile 75 years], with the majority being male (76.9%), and a mean calculated 30-day mortality risk of 10.0%. Early mortality was 12.7% (n = 333), due to cardiac causes (n = 266), neurological causes (=22), balloon-related causes (n = 5) and other causes (n = 40). A composite end point of all vascular complications occurred in 7.2% of patients, and leg ischaemia was observed in 1.3% of patients. The most important predictors of early mortality were peripheral vascular disease [odds ratio (OR) 1.63], postoperative dialysis requirement (OR 10.40) and vascular complications (OR 2.57).CONCLUSIONSThe use of the perioperative IABP proved to be safe and demonstrated relatively low complication rates, particularly for leg ischaemia. As such, we believe that specialists should not be held back to use this widely available treatment in high-risk cardiac surgical patients when indicated.     

Molecular diagnostic tools for the detection of nodal micrometastases in prostate cancer patients undergoing radical prostatectomy with extended pelvic lymph node dissection: a prospective study

Background: Routine pathological examination can miss micro-metastatic tumor foci in the lymph nodes (LN) of patients with prostate cancer (PCa) that undergo radical prostatectomy and pelvic lymph node dissection (PLND). The aim of the present prospective study was to evaluate the impact of micrometastases assessed by serial section (SS), immunohistochemistry (IHC), and Real-time Polymerase Chain Reaction (RT-PCR) in patients undergoing radical prostatectomy with extended PLND. Materials and methods: 32 consecutive patients who underwent radical prostatectomy with extended PLND (obturator, internal/external and distal 2cm common iliac lymph-nodes (LN)) for intermediate (clinical T1c-T2 and PSA:10-20 ng/mL and clinical Gleason Score = 7) or high (clinical stage T3 or PSA>20 or clinical Gleason Score = 8-10) PCa were enrolled. The nodes were processed by the one uropathologist, both according to the routine pathological examination (analysis of the central section for 4 mm nodes or every 2 mm for LN>4 mm), which served as comparative method, both according to SS, IHC with antibodies against PSA and broad-spectrum Cytokeratins (BSCK), and quantitative RT-PCR targeting PSA, PSMA (PS Membrane Antigen), and Glucuronidase-S-Beta (GUSB) mRNA, that are over-expressed in prostatic cancer cells. Results: A total of 628 LN were analyzed, with a mean number of LN removed of 19.6 (SD = 7.2). Applying the routine pathological examination, 10 (31.2%) patients and 23 (3.9%) LN resulted positive for nodal involvement, with mean positive LN of 2.2 (SD = 1.4). After applying the SS and the molecular method of analysis (IHC and RT-PCR), micrometastases were found in 7 LN (SS showed micrometastases in 3 of them, IHC in 6 of them and RT-PCR in 7 of them); a total of 3 (9.3%) node-negative patients showed micrometastases at routine pathological examination (in 2 patients with RT-PCR and in 1 with IHC). Conclusions: The significance of micrometastases in PCa and the potential therapeutic role of PLND is not yet clarified, but the molecular analysis of the LN can detect a significant percentage of patients who harbor micro-metastatic PCa missed at routine pathological examination, and can enhance the accuracy of lymphadenectomy as a staging method.     

Association between trauma and cancer of the testis: the importance of self-palpation of the testis for the early detection: two case reports

introduction: Cancer of the testis is not always early detected and recognised, both by the physician and by the patient: sometimes physicians do not make an accurate genitals exam while patients often underestimate this problem. Case reports: Case I: 42-year-old man accepted from another hospital's Emergency, because of pain and edema of the right testis after a recent trauma on the gonad. At US, evidence of increased volume of the right testis with a large intraparenchymal hematoma. The markers were higher than normal. We performed a right orchiecthomy. The pathologist noted the presence of a mixed cancer of the testis (95% embryonal, 5% seminoma). Case II: 49-year-old man with hematuria, accepted from Emergency. The abdominal US revealed the presence of a voluminous neoformation (diameter of 12 cm) of the right kidney with neoplastic thrombosis of the right kidney vein. At the general physical exam, we detected the presence of an increased right testis, that at the US appared to be suspicious for cancer. Tumor markers were normal with the exception of αFP. We performed right nephro-adrenalectomy, right orchiectomy and removal of local nodes. The definitive histological examination demonstrated the presence of a seminoma of the testis and papillary carcinoma of the kidney with node metastasis. Discussion: Current studies showed an association between trauma and cancer of the testis, even if some authors did not find this association because they consider that patients with trauma undergo US and in that occasion cancer is incidentally detected. Conclusions: The association between trauma and cancer of the testis is controversial in current studies. Furthermore screening for the cancer of the testis does not seem to be useful, even if the self- and the physician's palpation of the testis seem to be very important because in these two cases they should allow the early detection of the condition, with a resulting better prognosis.
