The proposed framework can also be used to assess individual patient's risk and thus assisting in delivering personalized medicine.Extensive-stage small-cell lung cancer (ES-SCLC) is an aggressive cancer that remains very hard to treat. The life expectancy of a patient diagnosed with this disease has not changed over the past three decades. Recently, three large clinical studies showed a survival benefit by adding an anti-programmed death (ligand) 1 (PD-(L)1 antibody to the current chemotherapy regimen. Although significant and important, the benefit seems less than what has been achieved in patients with non-small-cell lung cancer treated with chemoimmunotherapy. A number of hypotheses have been explored to explain this discrepancy. find more Here, we hypothesise that the current chemotherapy backbone in ES-SCLC does not contain the optimal drugs to trigger immunogenic cell death and therefore does not induce a synergy between chemotherapy and immune checkpoint inhibitor therapy. Thereby, we advocate that doxorubicin treatment instead of etoposide should be reconsidered as standard-of-care (SoC) first-line treatment of SCLC.

Sentinel lymph node biopsy (SNB) still remains a key procedure to appropriately stage melanoma patients and to select those who are candidate to novel treatments with immunotherapy and targeted therapy in the adjuvant setting. The impact of timing of SNB on disease-free survival (DFS) and overall survival (OS) is still unclear.

The study was conducted at 6 Italian Melanoma Intergroup (IMI) centres and included 8953 consecutive clinical stage I-II melanoma patients who were diagnosed, treated, and followed up between November 1997and March 2018. All patients were prospectively included in dedicated IMI database. Multivariable Cox regression analyses were performed to investigate how baseline characteristics and time interval until SNB are related to DFS and OS.

Considering the whole population, at multivariable analysis, after adjusting for age, gender, Breslow thickness, site, ulceration, and the SNB status, a delay in the timing of SNB was associated with a better DFS (adjusted hazard ratio [aHR, delayed versus early SNB] 0.98, 95% confidence interval [CI] 0.97-0.99, p<0.001) and OS (aHR 0.98, 95% CI 0.97-0.99, p=0.001). Specifically, in patients with a negative SNB status, a beneficial impact of delayed SNB (i.e. at least 32 days after primary excision) was confirmed for DFS (aHR 0.70, 95%CI 0.63-0.79, p<0.001) and OS (aHR 0.69, 95%CI 0.61-0.78, p<0.001), whereas in those with a positive SNB status, DFS (aHR 0.96, 95%CI 0.84-1.09, p=0.534) and OS (aHR 0.94 95%CI 0.81-1.08, p=0.374) were not significantly different in patients with early or delayed SNB.

Our study does not support a strict time interval for SNB. These results may be useful for national guidelines, for counselling patients and reducing the number of high urgency referrals.

Objectives were to characterize the role of serotonin in glucose and insulin metabolism in dairy calves with increased serotonin bioavailability. Milk replacer was supplemented with saline, 5-hydroxytryptophan (90 mg/d), or fluoxetine (40 mg/d) for 10-d (n = 8/treatment). Blood was collected daily during supplementation and on days 2, 7, and 14 during withdrawal. Calves were euthanized after 10-d supplementation or 14-d withdrawal periods to harvest liver and pancreas tissue. 5-hydroxytryptophan increased circulating insulin concentrations during the supplementation period, whereas both treatments increased circulating glucose concentration during the withdrawal period. The liver and pancreas of preweaned calves express serotonin factors (ie, TPH1, SERT, and cell surface receptors), indicating their ability to synthesize, uptake, and respond to serotonin. Supplementation of 5-hydroxytryptophan increased hepatic and pancreatic serotonin concentrations. After the withdrawal period, fluoxetine cleared from the pancreas but not liver tissue. Supplementation of 5-hydroxytryptophan upregulated hepatic mRNA expression of serotonin receptors (ie, 5-HTR1B, -1D, -2A, and -2B), and downregulated pancreatic 5-HTR1F mRNA and insulin-related proteins (ie, Akt and pAkt). Fluoxetine-supplemented calves had fewer pancreatic islets per microscopic field with reduced insulin intensity, whereas 5-hydroxytryptophan supplemented calves had increased islet number and area with greater insulin and serotonin and less glucagon intensities. After the 14-d withdrawal of 5-hydroxytryptophan, hepatic mRNA expression of glycolytic and gluconeogenic enzymes were simultaneously downregulated. Improving serotonin bioavailability could serve as a potent regulator of endocrine and metabolic processes in dairy calves.Inadequate milk production by sows often limits the growth of piglets. A successful lactation requires prolactin (PRL)-induced differentiation of the alveolar epithelium within the mammary glands of sows between days 90-110 of gestation. We hypothesized that induction of late gestational hyperprolactinemia in primiparous sows by oral administration of the dopamine antagonist metoclopramide (MET) would enhance mammary epithelial differentiation, milk yield, and piglet growth rate and that these effects would carry over into a subsequent lactation. Twenty-six gilts were assigned to receive either MET (n = 13, 0.8 mg/kg) or vehicle (CON, n = 13) twice daily from days 90-110 of gestation. The same sows were followed into their second lactation without additional treatment. On day 90 of gestation, circulating PRL concentrations peaked 45 min after feeding MET (P less then 0.001) and then returned to baseline 3 h later. This response occurred daily out to day 104 of gestation (P less then 0.05). Compared with CON, MET-treated gilts had enlarged alveoli on gestation day 110 (P less then 0.
