Phase II trial of fortnightly irinotecan (CPT-11) in the treatment of colorectal cancer patients resistant to previous fluoropyrimidine-based chemotherapy

Introduction This phase II study investigated the anti-tumour activity and toxicity of CPT-11 (250 mg/m2 i.v. infusion over 60 minutes) administered every 2 weeks as second-line chemotherapy in patients with advanced colorectal cancer (CRC). Material and methods Patients (n=63) with histology diagnosis of advanced CRC and proven resistance to previous fluoropyrimidine therapy were enrolled. Results A total of 510 CPT-11 cycles were administered, with a mean of 8 cycles per patient (range: 1–32). The median relative dose intensity was 93%. Partial response (PR) was obtained in 11 patients (17.5%; 95%CI: 8.1%–26.7%) and 29 patients (46.0%) showed stable disease (clinical benefit of 63.5%). The median duration of response was 6.8 months (95%CI: 6.1–7.5 months), median survival was 8.8 months (95%CI: 6.3–11.5 months) and median time to disease progression was 4.5 months (95%CI: 3.9–5.0 months). Overall, this schedule of CPT-11 chemotherapy was well tolerated by the patient. Neutropenia was the most frequent grade 3/4 haematological toxicity (20.6% of patients and 4.1% of cycles). Neutropenia with concurrent fever or infection occurred in 7 patients (11.1%). Late onset diarrhoea was the most frequent grade 3/4 non-haematological toxicity (19.0% of patients and 2.3% of cycles). Other, lower-incidence, toxicities were anaemia, fever, infection, mucositis, nausea and vomiting. There were no toxic deaths. Conclusions We found that CPT-11, administered as 250 mg/m² i.v. infusion over 60 minutes every 2 weeks, was active and well tolerated schedule in the second-line chemotherapy of advanced CRC patients. This bi-weekly scheme could be used as an alternative to the weekly or the every-three-week schedule as well as in combined therapies with other chemotherapeutic agents for the treatment of advanced, metastatic, CRC.     

Takotsubo Syndrome during COVID-19 Pandemic in the Veneto Region,Italy

Background: During the COVID-19 pandemic, the risk of SARS-CoV-2 infection, the public health measures of social distancing, the freedom limitations, quarantine, and the enforced homeworking under the lockdown period, as well as medical causes including COVID-19 infection per se, may have caused major emotional distress, especially in the most vulnerable patients. We aimed to evaluate the variations in the number of admissions due to Takotsubo syndrome (TTS) during the COVID-19 pandemic in the Veneto region. Methods: We retrospectively reviewed and analyzed the number of admissions because of TTS in 13 Divisions of Cardiology located in the Veneto region, the northeastern area of Italy, covering a population of more than 2.5 million inhabitants, during the two major pandemic waves of COVID-19 (the first between 15 March and 30 April 2020 and the second between 15 November and 30 December 2020) that occurred in 2020. Results: In total, 807 acute coronary syndromes were admitted in the 13 enrolling hospitals. Among these, 3.9% had TTS. Compared to the corresponding 2018 and 2019 time periods, we observed a significant increase in the number of TTS cases (+15.6%, p = 0.03 and +12.5%, p = 0.04, comparing 2018 to 2020 and 2019 to 2020, respectively). Geographical distribution of the TTS cases reflected the broad spread of the SARS-CoV-2 infection with a significant direct relationship between TTS incidence and the number of COVID-19 infections according to Pearson’s correlation (r = 0.798, p < 0.001). Conclusions: The higher incidence of TTS during the 2020 COVID-19 pandemic waves, especially in the areas that were hit hardest in terms of morbidity and mortality by the SARS-CoV-2 infection, suggest a strong direct and/or indirect role of COVID-19 in the pathogenesis of TTS.     

The Relationship between Serum Adipokines,miR-222-3p,miR-103a-3p and Glucose Regulation in Pregnancy and Two to Three Years Post-Delivery in Women with Gestational Diabetes Mellitus Adhering to Mediterranean Diet Recommendations

The San Carlos Gestational Diabetes Mellitus (GDM) prevention study, a nutritional intervention RCT based on a Mediterranean Diet (MedDiet), has been shown to reduce the incidence of GDM. The objective of this study is to investigate the relationship of leptin, adiponectin, interleukin-6 (IL-6), tumour necrosis factor-alpha (TNF-α), insulin and HOMA-IRand circulating miRNAs (miR-29a-3p, miR-103a-3p, miR-132-3p, miR-222-3p) with the appearance of GDM and with MedDiet-based nutritional intervention, at 24–28 gestational weeks (GW), and in glucose regulation 2–3 years post-delivery (PD). A total of 313 pregnant women, 77 with GDM vs. 236 with normal glucose tolerance (NGT), 141 from the control group (CG, MedDiet restricting the consumption of dietary fat including EVOO and nuts during pregnancy) vs. 172 from the intervention group (IG, MedDiet supplemented with extra virgin olive oil (EVOO) and pistachios during pregnancy) were compared at Visit 1 (8–12 GW), Visit 2 (24–28 GW) and Visit 3 (2–3 years PD). Expression of miRNAs was determined by the Exiqon miRCURY LNA RT-PCR system. Leptin, adiponectin, IL-6 and TNF-α, were measured by Milliplex^® immunoassays on Luminex 200 and insulin by RIA. Women with GDM vs. NTG had significantly higher leptin median (Q1–Q3) levels (14.6 (9.2–19.4) vs. 9.6 (6.0–15.1) ng/mL; p < 0.05) and insulin levels (11.4 (8.6–16.5) vs. 9.4 (7.0–12.8) µUI/mL; p < 0.001) and lower adiponectin (12.9 (9.8–17.2) vs. 17.0 (13.3–22.4) µg/mL; p < 0.001) at Visit 2. These findings persisted in Visit 3, with overexpression of miR-222-3p (1.45 (0.76–2.21) vs. 0.99 (0.21–1.70); p < 0.05)) and higher levels of Il-6 and TNF-α. When the IG is compared with the CG lower levels of insulin, HOMA-IR-IR, IL-6 levels at Visit 2 and 3 and leptin levels only at Visit 2 were observed. An overexpression of miR-222-3p and miR-103a-3p were also observed in IG at Visit 2 and 3. The miR-222-3p and miR103a-3p expression correlated with insulin levels, HOMA-IR, IL-6 and TNF-α at Visit 2 (all p < 0.05). These data support the association of leptin, adiponectin and insulin/HOMA-IR with GDM, as well as the association of insulin/HOMA-IR and IL-6 and miR-222-3p and miR-103a-3p expression with a MedDiet-based nutritional intervention.     

Depressive symptoms and their correlates among immigrant Mexican women in the United States

Correlates of depressive symptomatology and caseness are examined for a survey sample of N = 1825 poor Mexican immigrant women in San Diego County, California. The Center for Epidemiologic Studies--Depression (CES--D) checklist is tested against a variety of demographic variables as well as health status and service utilization rates. Statistically significant associations were found between CES--D and education, years in the United States, income, marital status and number of adults in household. Also significant were associations with health status, confidant support and recent, traumatic life event. Utilization rates point to medical doctors as the major source of formal treatment and a heavy reliance on family and friends. The implications of the high disorder rates for diagnosis and treatment among immigrants are discussed.     

Efficacy of a Fibrin Sealant (Tissucol Duo) for the Preventionof Lymphocele after Laparoscopic Pelvic Lymphadenectomy:A Randomized Controlled Trial

Study ObjectiveTo assess the efficacy of Tissucol Duo (Baxter AG, Vienna, Austria) fibrin sealant in decreasing the incidence of lymphocele (LC) after pelvic laparoscopic lymph node dissection using harmonic shears.DesignRandomized controlled trial (Canadian Task Force classification level I).SettingTertiary referral and educational center.PatientsSeventy-four patients randomized to the use of sealant per hemipelvis.InterventionFibrin sealant.Measurements and Main ResultsAfter bilateral pelvic lymphadenectomy a fibrin sealant was used in 1 hemipelvis but not the other, applied in 41 patients (55.4%) to the left and 33 patients (44.6%) to the right hemipelvis. The primary outcome was the incidence of LC after surgery in symptomatic and asymptomatic patients. Imaging (ultrasound, computed tomography, and magnetic resonance) was performed to detect LC at 3, 6, and 12 months after surgery. Overall, 26 patients (35.1%) developed LC, and 4 were symptomatic (5.4%). Allowing patients to serve as their own treatment group and control, the hemipelvis treated with Tissucol Duo corresponding to the treatment group and that not treated to the control group, LCs were found in 17 (23%) and 14 (19%) cases, respectively, but the difference was not significant. The mean initial LC maximum diameter was 27.1 mm (standard deviaiotn, 35.2), and LCs tended to decrease in size during the first year to a mean of 8.7 mm.ConclusionApplication of Tissucol Duo fibrin sealant after laparoscopic pelvic lymphadenectomy using ultrasonic shears does not decrease the occurrence of symptomatic or asymptomatic LC.     

Experiencia y tratamiento anestésico en el implante transcatéter de la prótesis valvular aórtica autoexpandible CoreValve®

ObjectiveTo analyze the experience and anesthetic management in the transcatheter implantation of the CoreValve^® self-expanding aortic valve, in a university tertiary hospital.Material and methodsObservational analytical review of data incorporated into a prospectively maintained database of 142 patients diagnosed with severe aortic stenosis who underwent implantation of a CoreValve^® aortic self-expanding aortic valve between December 2007 and December 2012.ResultsThe mean age of patients was 82.5 ± 6.1 years and the logistic EuroSCORE was 14.9 ± 11.2. General anesthesia was used in 107 patients (75.3%), with local anesthesia with sedation in 35 (24.6%). Local anesthesia and sedation was associated with a lower requirement of vasoactive drugs (P = .003) during implantation. No statistically significant differences were found between the 2 anesthetic techniques in the duration of the procedure, hospital stay, or morbimortality. The success rate was 97.1%. The most common complication was conduction disorders that required implantation of a permanent pacemaker in 46 patients (32.3%). There was no intraoperative mortality, and all-cause mortality at 30 days was 6.3%, with a one-year survival estimated by the Kaplan-Meier of 83.1%.ConclusionsThis study confirms that in patients with severe aortic stenosis and high surgical risk, transcatheter implantation of aortic valve is a safe and effective alternative. Both, general anesthesia and local anesthesia with sedation are valid options, depending on the experience of the team.
