RESUMO

Endometrial cancer and uterine sarcoma represent the two major types of uterine cancer. In advanced stages, both cancer entities are challenging to treat and correlate with a meagre survival and prognosis. Hyperthermic Intraperitoneal Chemotherapy (HIPEC) is a form of localized chemotherapy that is heated to improve the chemotherapeutic effect on peritoneal metastases. The aim of the current review is to study the role of HIPEC in the treatment of uterine cancer. A literature review was conducted using the MEDLINE and LIVIVO databases with a view to identifying relevant studies. By employing the search terms "hyperthermic intraperitoneal chemotherapy", "uterine cancer", "endometrial cancer", and/or "uterine sarcoma", we managed to identify 26 studies published between 2004 and 2023. The present work embodies the most up-to-date, comprehensive review of the literature centering on the particular role of HIPEC as treatment modality for peritoneally metastasized uterine cancer. Patients treated with cytoreductive surgery, alongside HIPEC, seem to profit from not only higher survival but also lower recurrence rates. Factors such as the completeness of cytoreductive surgery, the peritoneal cancer index, the histologic subtype, or the applied chemotherapeutic agent, all influence HIPEC therapy effectiveness. In summary, HIPEC seems to represent a promising treatment alternative for aggressive uterine cancer.

RESUMO

Unresectable hepatocellular carcinoma (HCC) is an advanced primary liver malignancy with a poor prognosis. The Food and Drug Administration (FDA) has, to date, approved nivolumab, pembrolizumab, ramucirumab, nivolumab/ipilimumab, atezolizumab/bevacizumab, as well as tremelimumab/durvalumab, as first- or second-line monoclonal antibodies (mAbs) for unresectable HCC. The present review examines the current state of knowledge, and provides a useful update on the safety and efficacy of these therapeutic agents, thus attempting to define the suitability of each mAb for different patient subgroups.

RESUMO

OBJECTIVES: The aim of this study was to investigate the impact of breast reconstruction time (immediate/at a later time) on women's quality of life, self-esteem, feelings of guilt, and shame. In addition, the study aimed to investigate the association between time till reconstruction in women with later reconstruction on these parameters. METHODS: Data collection for the study was conducted from a sample of 150 women with breast cancer who had undergone reconstruction. Breast-Q, Rosenberg Self-Esteem Scale, and State Shame and Guilt Scale questionnaires were used to study the above variables. RESULTS: Immediate reconstruction was associated with higher psychosocial and sexual well-being scores (p = 0.014 and 0.016, respectively). No other quality of life parameters, neither self-esteem, nor feelings of guilt, shame, and pride, were associated with having a mastectomy and reconstruction at the same time or not. Furthermore, for women who did not have immediate reconstruction, the time elapsed until reconstruction was not associated with quality of life, self-esteem, feelings of guilt, shame, and pride. SIGNIFICANCE OF RESULTS: This study highlights the importance of simultaneous mastectomy and breast reconstruction, as it is associated with higher psychosocial and sexual quality of life. Therefore, simultaneous breast reconstruction is imperative to be provided by health systems.

RESUMO

Peritoneal adhesions are responsible for several and sometimes severe clinical phenotypes remaining a major problem for many patients today. Adhesions are formed within the peritoneal cavity as a result of surgery, inflammation, or injury and can cause a range of clinical symptoms, including abdominal pain, small bowel obstruction, infertility, and other complications. The incidence of peritoneal adhesions remains high as it is estimated that more than 50% of patients who undergo abdominal surgery will develop adhesions. Although advancements in surgical techniques and perioperative management have been developed, the risk of adhesion formation cannot be eliminated, and thus, the development of effective prevention strategies and treatments remains a priority in the field of surgery. In this review, we summarize the cellular and molecular mechanisms involved in the peritoneal adhesions, but also the experimental therapy approaches that have been investigated toward a solution to their possible clinical phenotypes.

RESUMO

Hepatocellular carcinoma (HCC) remains one of the most common malignancies and the third cause of cancer-related death worldwide, with surgery being the best prognostic tool. Among the well-known causative factors of HCC are chronic liver virus infections, chronic virus hepatitis B (HBV) and chronic hepatitis virus C (HCV), aflatoxins, tobacco consumption, and non-alcoholic liver disease (NAFLD). There is a need for the development of efficient molecular markers and alternative therapeutic targets of great significance. In this review, we describe the general characteristics of HCC and present a variety of targeted therapies that resulted in progress in HCC therapy.

RESUMO

Background and Objectives: This study was designed to evaluate platelet-rich plasma (PRP) as a method of pleurodesis in a rabbit model. Pleurodesis with PRP was compared against the gold-standard use of talc. The secondary evaluation assessed the ideal time for achieving pleurodesis. Materials and Methods: 25 healthy New Zealand white rabbits were assigned to three groups, as follows: 12 animals in the first and second groups, as well as one animal with no intervention in the final group, which was used as a control. The talc pleurodesis group (baseline) underwent pleurodesis with sterile talc, which is the gold-standard sclerosing agent used for pleurodesis. The PRP group underwent pleurodesis using autologous PRP. The last group had one rabbit with no intervention. A total of 12 rabbits (n = 6 for the talc pleurodesis group and n = 6 for the PRP group) were sacrificed 3 days (72 h) after the intervention, and 12 rabbits (n = 6 for the talc pleurodesis group and n = 6 for the PRP group) were sacrificed 6 days (144 h) after the intervention. In both the talc and PRP group, FBC and CRP were measured before the intervention and in 3 or 6 days afterwards, respectively. The pleura and the lungs were evaluated histopathologically. Results: Macroscopically, there were no statistically significant differences between the two groups. In terms of microscopic findings, there were no statistically significant differences in inflammatory reactions provoked in the visceral and parietal pleura between the PRP and talc. In addition, with talc pleurodesis, a foreign-body reaction was observed in about 50% of the cases, which was not observed with PRP. In terms of inflammation between 3 and 6 days, there were no statistically significant differences with PRP, there was only a statistically significant difference between 3 and 6 days regarding the parietal pleura in the talc group. Conclusions: The instillation of autologous PRP in the pleural cavity shows promise in achieving pleurodesis. The efficacy of PRP as a pleurodesis agent should be examined further.

RESUMO

Background: Intra-abdominal adhesion formation is still unavoidable and a cause of significant morbidity in abdominal surgery. Platelet-rich plasma gel and hyaluronic acid have been studied for their protective of therapeutic effects on adhesions. The aim of the present study is to compare Platelet-rich plasma and hyaluronic acid in adhesion prevention. Material and method: Twenty-seven Sprague-Dawley rats were randomly allocated into three equal groups(n=9). Surgical trauma was used to induce adhesion formation. After trauma, 1 ml normal saline was instilled in the peritoneal cavity in control group (n=9), 1 ml liquid Hyaluronic acid (25 mg/ml) was instilled in group A (n= 9) and 1 ml of platelet-rich plasma was instilled in group B (n = 9). Four weeks after the laparotomy, a repetitive laparotomy was performed and adhesions were examined microscopically and macroscopically. Results: Platelet-rich plasma gel and hyaluronic acid both reduce the extent and grade of adhesions macroscopically. Interestingly, PRP turns out to be superior in the reduction of tenacity and adhesion area. Moreover, platelet-rich plasma ameliorates abdominal adhesion formation by reducing neutrophils, fibrosis, and inflammation. Conclusion: The results indicate that platelet-rich plasma gel surpasses hyaluronic acid in abdominal adhesion prevention.

RESUMO

BACKGROUND: Fascin is the main actin cross-linker protein that regulates adhesion dynamics and stabilizes cell protrusion, such as filopodia. In human cancer, fascin expression correlates with aggressive clinical features. This study aimed to determine the expression patterns of fascin-1 and assessed its prognostic significance in colorectal cancer. METHODS: One hundred eleven specimens of patients with primary resectable colorectal cancer were examined via immunohistochemistry for the expression of fascin-1, and the results were correlated with clinicopathological characteristics and survival data. RESULTS: Fascin-1 staining displayed strong intensity in the cytoplasm of the colorectal cancer cells and endothelial cells of tumor blood vessels. Moderate to high fascin-1 expression was associated with progressive anatomic disease extent (p < 0.001), higher T classification (p = 0.007), the presence of lymph node (p < 0.001) and distant metastasis (p = 0.002), high grade tumors (p = 0.002) and vascular invasion (p < 0.001). Patients displaying moderate and high fascin-1 expression demonstrated a significantly worse 5-year overall survival [HR; 3.906, (95%CI) = 1.250-12.195] and significantly worse 3-year progression-free survival [HR; 3.448, (95%CI) = 1.401-8.475] independent of other clinicopathological characteristics. Besides, high fascin-1 expression in early-stage cancer only was associated with a dismal prognosis. CONCLUSIONS: High fascin-1 expression in colorectal cancer is an independent negative prognostic factor for survival, increasing the risk for disease recurrence or death almost by sevenfold. Fascin-1 expression could be potentially utilized to identify high-risk patients prone to metastasis already in early-stage disease.

RESUMO

OBJECTIVES: Autosomal dominant polycystic kidney disease (ADPKD) is characterised by increased rates of cardiovascular complications leading to significant morbidity and mortality. This meta-analysis aims to evaluate whether the disease is linked to endothelial dysfunction and arterial stiffness during its early stages. METHODS: Medline, Scopus, CENTRAL, Web of Science, Clinicaltrials.gov and Google Scholar databases comparing ADPKD patients with preserved renal function to healthy controls were included. The outcomes of interest were brachial flow-mediated dilatation, carotid-femoral pulse wave velocity, augmentation index, carotid intima-media thickness and central systolic blood pressure, plasma ADMA or homocysteine levels. Standardised mean differences (SMDs) were estimated by a random-effects model in R-3.6.3. RESULTS: A total of 27 studies were included, comprising 1967 individuals. ADPKD was linked to significantly lower flow-mediated dilatation (SMD: -1.44, 95% CI: [-2.35, -0.53]) and higher pulse wave velocity (SMD: 1.44, 95% CI: [0.22, 2.66]) and carotid intima-media thickness (SMD: 1.02, 95% CI: [0.57, 1.47]). No significant associations were noted regarding augmentation index (SMD: 0.62, 95% CI: [-0.19, 1.43]) and central systolic blood pressure (SMD: 1.84, 95% CI: [-0.12, 3.80]). Plasma homocysteine was significantly higher in ADPKD (SMD: 0.81, 95% CI: [0.16, 1.45]), while no difference was calculated for ADMA levels (SMD: 1.14, 95% CI: [-0.25, 2.53]). CONCLUSIONS: Early-stage ADPKD patients present increased vascular stiffness and endothelial dysfunction, as reflected by low flow-mediated dilatation and elevated values of pulse wave velocity, carotid intima-media thickness and plasma homocysteine. The exact effects of early arterial stiffness on long-term outcomes remain to be elucidated.

RESUMO

AIMS/HYPOTHESIS: SGLT-2 inhibitors (SGLT-2i) have been studied as potential treatments against NAFLD, showing varying beneficial effects. The molecular mechanisms mediating these effects have not been fully clarified. Herein, we investigated the impact of empagliflozin on NAFLD, focusing particularly on ER stress, autophagy and apoptosis. METHODS: Five-week old ApoE(-/-) mice were switched from normal to a high-fat diet (HFD). After five weeks, mice were randomly allocated into a control group (HFD + vehicle) and Empa group (HFD + empagliflozin 10 mg/kg/day) for five weeks. At the end of treatment, histomorphometric analysis was performed in liver, mRNA levels of Fasn, Screbp-1, Scd-1, Ppar-γ, Pck-1, Mcp-1, Tnf-α, Il-6, F4/80, Atf4, Elf2α, Chop, Grp78, Grp94, Χbp1, Ire1α, Atf6, mTor, Lc3b, Beclin-1, P62, Bcl-2 and Bax were measured by qRT-PCR, and protein levels of p-EIF2α, EIF2a, CHOP, LC3II, P62, BECLIN-1 and cleaved CASPASE-8 were assessed by immunoblotting. RESULTS: Empagliflozin-treated mice exhibited reduced fasting glucose, total cholesterol and triglyceride serum levels, as well as decreased NAFLD activity score, decreased expression of lipogenic enzymes (Fasn, Screbp-1c and Pck-1) and inflammatory molecules (Mcp-1 and F4/80), compared to the Control group. Empagliflozin significantly decreased the expression of ER stress molecules Grp78, Ire1α, Xbp1, Elf2α, Atf4, Atf6, Chop, P62(Sqstm1) and Grp94; whilst activating autophagy via increased AMPK phosphorylation, decreased mTOR and increased LC3B expression. Finally, empagliflozin increased the Bcl2/Bax ratio and inhibited CASPASE-8 cleavage, reducing liver cell apoptosis. Immunoblotting analysis confirmed the qPCR results. CONCLUSION: These novel findings indicate that empagliflozin treatment for five weeks attenuates NAFLD progression in ApoE(-/-) mice by promoting autophagy, reducing ER stress and inhibiting hepatic apoptosis.

RESUMO

OBJECTIVES: Colistin represents a polypeptide used for the treatment of MDR microorganisms, although the optimal dosing strategy is under investigation. The present meta-analysis aims to determine whether the administration of a colistin loading dose in patients receiving high-dose maintenance regimens changes the rates of treatment success and the risk of nephrotoxicity. METHODS: Medline, Scopus, CENTRAL, Clinicaltrials.gov and Google Scholar were systematically searched from inception to 18 November 2019. Studies were considered eligible if they reported clinical outcomes among patients receiving high-dose colistin therapy with and without the administration of a loading dose. Meta-analysis was performed by fitting a random-effects model. RESULTS: Eight (three prospective and five retrospective cohort) studies were included, comprising 1115 patients. The administration of a colistin loading dose was associated with significantly higher microbiological [risk ratio (RR) = 1.23, 95% CI = 1.10-1.39] but not clinical (RR = 1.04, 95% CI = 0.87-1.24) success. No significant associations were calculated for nephrotoxicity (RR = 1.31, 95% CI = 0.90-1.91) and mortality (RR = 1.03, 95% CI = 0.82-1.29) risk. The results remained stable after adjustments for small sample size, credibility ceilings, publication bias and risk of bias. CONCLUSIONS: Observational evidence suggests that the administration of a colistin loading dose in patients receiving high maintenance dosage regimens is significantly associated with higher rates of microbiological response, but does not change clinical cure, mortality or nephrotoxicity risk. The dosing regimen that would provide the optimal balance between treatment efficacy and safety needs to be determined by future randomized controlled trials.

RESUMO

Background: Metastatic disease in colorectal cancer represents a major cause of significant cancer-associated morbidity and mortality. L1CAM is a stem cell marker, cell adhesion molecule, belongs to the immunoglobulin superfamily of cell adhesion molecules (IgCAM) and it is aberrantly expressed in several different types of human solid tumors. The aim of the present study was to assess the expression patterns of L1CAM and its clinical significance in colorectal cancer.Patients and methods: Surgical specimens of 109 patients with primary resectable colorectal cancer were examined for L1CAM expression via immunohistochemistry and the results were correlated with clinical and survival data.Results: L1CAM expression was significantly correlated with advanced stage of disease (p < .001), higher T classification (p = .040), the presence of lymph node (p < .001) and distant metastasis (p = .011). Patients displaying high L1CAM expression demonstrated a dismal three-year progression free survival (29.7% vs 87.1%, p < .001) and five-year overall survival (39.9% vs 87.7%, p < .001). Multivariate analysis using Cox proportional hazard models revealed high L1CAM expression as a prognostic marker of dismal progression free (HR 0.187, 95%CI = 0.075-0.467, p < .0001) and overall survival (HR 0.154, 95%CI = 0.049-0.483, p = .001) independent of other clinicopathological characteristics. Subgroup analysis comprised of patients with early stage disease only presented as well significantly worse progression free and overall survival when L1CAM exhibited high expression.Conclusions: Colorectal cancer patients displaying high expression of L1CAM harbor high risk for metastasis already in early stage disease identifying therefore a group of patients prone to dismal prognosis.

RESUMO

BACKGROUND AND AIMS: Refractory ascites represents a significant complication of decompensated cirrhosis, associated with increased mortality rates. The aim of this meta-analysis was to evaluate whether response to treatment with tolvaptan is associated with improved overall survival in cirrhotic patients with refractory ascites. METHODS: Medline, Scopus, Cochrane Central Register of Controlled Trials, Clinicaltrials.gov, and Google Scholar databases were systematically searched from inception to April 11, 2019. All studies that assessed the overall survival of patients with ascites depending on their response to tolvaptan were held eligible. RESULTS: Nine studies were included, with a total of 736 patients with cirrhosis and ascites. Response to tolvaptan was estimated to be linked to significantly improved overall survival (hazard ratio [HR] 0.42, 95% CI [0.31-0.58]). Subgroup analysis indicated that the same outcome was present when tolvaptan responsiveness was defined either as effective body weight loss (HR 0.44, 95% CI [0.30-0.63] or as effective sodium restoration (HR 0.35, 95% CI [0.20-0.61]. Sensitivity analysis suggested that the presence of hepatocellular carcinoma, the sample size, and the quality of the studies did not significantly affect the overall result of the meta-analysis. CONCLUSIONS: The outcomes of the meta-analysis support the prognostic role of tolvaptan response in patients with cirrhosis and refractory ascites, as it was shown to lead to significantly improved overall survival. These findings should be confirmed by future large-scale studies, while efficient biomarkers should be identified in order to accurately predict response to tolvaptan and discriminate patients that would benefit from its administration.

RESUMO

BACKGROUND AND AIM: Tolvaptan represents an oral V2 -receptor antagonist, which has been suggested as a promising add-on diuretic treatment for refractory ascites. The present meta-analysis aims to accumulate current evidence and identify which clinical and laboratory factors are linked to short-term response to tolvaptan therapy. METHODS: Medline, Scopus, Cochrane Central Register of Controlled Trials, Clinicaltrials.gov, and Google Scholar databases were searched from inception. All observational studies reporting the correlation of patients' characteristics with tolvaptan response were selected. RESULTS: Tolvaptan response was associated with significantly higher baseline body weight (mean difference: 4.59 kg, 95% confidence interval [CI]: [3.58, 5.61]), presence of hepatitis C (odds ratio: 1.59 95% CI: [1.18, 2.14]), lower blood urea nitrogen (BUN) (mean difference: -6.88 mg/dL, 95% CI: [-8.13, -5.63]), lower serum creatinine (mean difference: -0.17 mg/dL, 95% CI: [-0.30, -0.05]), lower C-reactive protein (mean difference: -1.43 mg/dL, 95% CI: [-2.52, -0.35]), and higher sodium levels (mean difference: 1.00 mEq/L, 95% CI: [0.45, 1.55]). The outcomes of bodyweight, hepatitis C, BUN, and C-reactive protein remain significant independently of response definition and risk of bias. CONCLUSIONS: The present findings suggest bodyweight, BUN, C-reactive protein, and hepatitis C as potential predictive factors of tolvaptan short-term response in patients with refractory ascites. Future studies are needed to introduce cut-off values and construct an optimal combined screening model.

RESUMO

INTRODUCTION: Recent studies have indicated that the damaging effects of stroke are not only limited to the brain. We sought to examine the changes of liver and renal enzymes in the acute phase of ischemic stroke and to investigate possible explanations and therapeutic options, concerning in particular the functional alterations of peripheral organs after administration of an anti-inflammatory agent. MATERIAL/METHODS: Twelve-week-old Wistar male rats were randomly divided into control and Cyclosporine groups (n = 10 each). Cyclosporine was given orally by gavage for 5 days prior to cerebral ischemia at a total volume of 15 mg/kg/day. All animals were subjected to 60 minutes focal ischemia by filament occlusion of the middle cerebral artery. Serum concentrations of Creatinine, Urea, SGOT, SGPT, and γGT were determined at the time before surgery and after 60 minutes brain ischemia. RESULTS: Comparing data of 2 time-points, in both groups the serum liver enzyme levels increased progressively during the ischemic period. The liver enzymes and Urea were significantly lower in the Cyclosporine group than in the control group and the levels of Creatinine were slightly higher in the Cyclosporine group, in both time-points. CONCLUSIONS: The detection of high liver enzyme serum levels in the acute phase of ischemic stroke implies the secondary effect of cerebral infraction on the peripheral organs and particularly on the liver function. Cyclosporine seems to exhibit a protective activity and to affect both liver and renal function after ischemic stroke.

RESUMO

BACKGROUND: Despite improvements in therapy of colorectal cancer, some patients will present occurrence of recurrence either locally or distantly. Tumor metastasis constitutes the major cause of cancer-associated morbidity and mortality. Nectin-1 belongs to the family of immunoglobulin-like cell adhesion molecules that contribute to the formation of cell-cell adhesions and regulate a series of cellular activities including cell polarization, differentiation, movement, proliferation, and survival. Expression of Nectin-1 in malignant tumors has been associated with aggressive tumor phenotypes. OBJECTIVES: The aim of the present study was to assess Nectin-1 expression patterns in colorectal cancer and to investigate its clinical significance. METHODS: Nectin-1 expression was assessed via immunohistochemistry in surgical specimens of a cohort comprised of 111 patients with primary resectable colorectal cancer. Results were correlated with clinicopathological characteristics and survival data. Progression-free survival was defined as the primary outcome of the present study. RESULTS: Nectin-1 was strongly expressed in the cytoplasm of colorectal cancer cells. High Nectin-1 expression was associated with advanced stage of disease (p = 0.012) and lymph node metastasis (p = 0.007). Progression-free survival of patients exhibiting high expression of Nectin-1 in the first 36 months after surgery was significantly worse compared to patients with low expression of Nectin-1 (55.7%, 95% CI = 47-70, vs. 82.1%, 95% CI = 69-93, p = 0.014) and independent of other clinicopathological characteristics (HR = 0.389, 95% CI = 0.156-0.972, p = 0.043). CONCLUSION: Nectin-1 expression in colorectal cancer is associated with a significantly worse 3-year progression-free survival identifying therefore a group of patients with high risk for early disease recurrence.

RESUMO

BACKGROUND: Sunitinib plays an important role in managing the metastatic renal cell cancer (mRCC). Sunitinib-induced hypothyroidism is a common side-effect of the drug. There have been attempts to link hypothyroidism with a better clinical outcome in sunitinib-treated (mRCC) patients. Our aim was to relate the impact of hypothyroidism to the survival of these patients. METHODS: We have evaluated 70 patients with mRCC that received sunitinib as a first line treatment. Thyroid-stimulating hormone (TSH) was measured at baseline, after 15 days of treatment (day-15) and at the end of the second cycle (day-75). Biomarker data and correlations with response were analysed with Microsoft Excel. Comparison results from Student's t-test with a p less than 0.05 were considered statistically significant. Kaplan-Meyer and log-rank tests were performed using GraphPad Prism 5 for Windows. RESULTS: Regarding the response to treatment, a progression-free survival (PFS) of 9.47 months and an overall survival (OS) of 22.03 months were demonstrated. Our data are consistent with published data by other authors. On day-15 from the beginning of the treatment an important number of patients exhibited a TSH elevation. On day-15 42.86% had a TSH over the upper normal limit and 50.0% at the end of the second cycle (day-75). TSH increased earlier in patients that exhibited an objective response (× 3.33 times the baseline values on day-15) than patients that exhibited disease stabilisation (× 2.18) or disease progression (× 1.59). Early increases in TSH were associated with a longer PFS (11.92 vs. 8.82 months, p = 0.0476) and a longer OS (3.10 vs. 1.08 years, p = 0.0011). CONCLUSIONS: Early TSH-increase is associated with a clinical benefit. The patients that showed at least a twofold increase of their baseline TSH, responded to therapy by stabilisation or by regression of disease. This is the only study to our knowledge which shows that early increases - 2 weeks from starting the treatment - in TSH levels have a prognostic value. Both PFS and OS of the patients who demonstrated a higher than a twofold rise were significantly longer than the PFS and the OS of the patients that presented a lower or no TSH-increase.

RESUMO

BACKGROUND Accumulating evidence has indicated that S100B protein may be involved in the pathophysiology of ischemia-reperfusion brain injury. Cyclosporine has been shown to have neuroprotective functions. This study investigated the effect of cyclosporine on S100B serum levels and the severity of brain tissue damage in a rat model of cerebral ischemia-reperfusion (I/R). MATERIAL AND METHODS Twelve-week-old Wistar male rats were randomly divided into Control I/R and Cyclosporine I/R groups (n=10 each). Cyclosporine was given orally by gavage for 5 days prior to cerebral I/R, at a total volume of 15 mg/kg/day. The Control group received an equal volume of saline. Body weight was measured and all animals were subjected to 60-min focal ischemia by filament occlusion of the middle cerebral artery. ELISA was used to assess the concentrations of serum S100B and development of brain infarct size and neurological outcomes were determined at 2 and 24 h after occlusion withdrawal. RESULTS Cyclosporine improved the neurological deficit score and decreased the cerebral infarct size and body weight. S100B serum levels were significantly elevated in Cyclosporine-treated rats compared with untreated Control rats during the reperfusion phase. Total infarct size was positively associated with S100B serum levels in the Control I/R group, but no significant correlation was observed in the Cyclosporine I/R group. CONCLUSIONS Cyclosporine seems to affect both ischemia-reperfusion brain tissue damage and S100B protein serum levels. S100B serum level appears to be a state marker for the severity of the cerebral ischemia-reperfusion, rather than a trait marker for Cyclosporine responsiveness.

RESUMO

WHAT IS KNOWN AND OBJECTIVE: Tumour lysis syndrome is an oncological emergency, characterized by rapid cytolysis leading to an abrupt rise of serum uric acid levels. The aim of the present meta-analysis is to evaluate the efficacy and safety of febuxostat as a preventive measure in patients at risk of tumour lysis syndrome development, by comparing it with allopurinol administration. METHODS: MEDLINE, Scopus, Cochrane Central Register of Controlled Trials, Clinicaltrials.gov and Google Scholar databases were searched from inception to 15 December 2018. All studies evaluating the effectiveness of febuxostat in preventing tumour lysis syndrome were held eligible. RESULTS AND DISCUSSION: Six studies were included with a total of 658 patients. Compared to allopurinol, febuxostat achieved a similar response rate (OR: 1.39, 95% CI: [0.55, 3.51]) and tumour lysis syndrome incidence (OR: 1.01, 95% CI: [0.56, 1.81]). Serum uric acid levels did not differ between the investigated groups at the second (MD: -0.21 mg/dL, 95% CI: [-1.30, 0.88]) and seventh (MD: -0.43 mg/dL, 95% CI: [-1.38, 0.51]) day of treatment. Elevation of liver function tests was the most common adverse effect, although its incidence was similar among patients treated with allopurinol and febuxostat. WHAT IS NEW AND CONCLUSIONS: The present meta-analysis suggests that febuxostat may serve as an effective alternative to allopurinol in the prevention of tumour lysis syndrome. Future large-scale studies should define the optimal febuxostat dosage, explore the most appropriate population for its administration and better define its safety profile.

RESUMO

PURPOSE: To report a single surgeon series of consecutive robotic right colectomies (RRC) performed for non-metastatic right colon cancer. METHODS: A retrospective review of a prospectively maintained database of patients who underwent elective robotic right colectomy for right colon adenocarcinoma was conducted. Patients with stage 0-III disease were included in the study. Outcomes evaluated included operative time, number of lymph nodes harvested, estimated blood loss, time to return of bowel function, length of hospital stay, complications and a minimum of 6-month follow up. RESULTS: Forty-five consecutive patients were included in this study. The mean operative time was 175 min, the mean lymph nodes harvested were 22 and the mean length of hospital stay was 5 days. The mean time to normal bowel function restoration and to discontinuation of patient-controlled analgesia was 2 days. The hospital post-operative courses were complicated in two patients by ileus and fever due to pulmonary atelectasia, respectively. No conversions to laparotomy, reoperations or 90-day deaths were recorded. CONCLUSIONS: Robotic colorectal surgery has gained a lot of supporters through the years although a debate still exists concerning the outcomes. The present study is one of the largest evaluating short-term results of RRCs performed by a single surgeon. We believe we demonstrated the safety and efficacy of RRC in the treatment of right colon nonmetastatic adenocarcinoma.
