Young psychopathology along with subconscious well-being: a network evaluation approach.
INTRODUCTION This study aimed to determine the impact of FOLFIRINOX neoadjuvant therapy on patients with non-metastatic borderline/locally advanced (BL/LA) pancreatic ductal adenocarcinoma (PDAC), in current practice. MATERIAL AND METHODS From 2010 to 2017, 258 patients with BL/LA PDAC from a single high-volume institution received FOLFIRINOX neoadjuvant treatment. RESULTS The 258 patients received a median number of 6 cycles of FOLFIRINOX (range, 3-16); 98 (38%) patients underwent curative surgery, and 160 (62%) continued medical treatment. A venous resection was performed in 57 patients (58%), and an arterial resection in 12 (12%). The postoperative 30- and 90-day mortality rates were 6.1% and 8.2%, respectively. Adjuvant chemotherapy was performed in 57 patients (59%). The median overall survival (OS) in patients who did (n = 98) or did not (n = 160) undergo surgical resection were 39 months and 19 months, respectively (P less then 0.001). In resected patients, the ASA 3 score (P less then 0.01), venous resection (P less then 0.01), hemorrhage (P less then 0.01), and R1 margin status (P = 0.03) were found to negatively influence the OS. The median OS was significantly higher in patients who did not require a venous resection (not reached vs. 26.5 months, P less then 0.001). CONCLUSIONS Neoadjuvant FOLFIRINOX provided a survival benefit in BL/LA PDAC patients, particularly in those who did not ultimately require venous resection. BACKGROUND Clinical factors, such as tumor thickness, ulceration and growth phase have a role as prognostic factors for stage I melanoma. GSK J4 in vivo However, it is still under debate whether these variables influence the related direct costs. We aimed to investigate which clinical factors represent direct health care "cost drivers" for stage I melanoma. MATERIALS AND METHOD Analyses were conducted on a cohort of patients diagnosed with stage I melanoma. Differences in the costs incurred by different groups of patients were examined using Mann-Whitney or Kruskal-Wallis non-parametric tests. Log linear multivariate analysis was used to identify the clinical drivers of the total direct costs one and two years after diagnosis. The study was conducted from the perspective of Italy's National Health care System. RESULTS One year after diagnosis, patients whose melanomas had a Breslow thickness ≥0.8 mmin (compared with those with lower thickness) and a vertical growth phase (compared with those with radial growth) incurred higher costs for hospitalization, as well as higher overall costs. One year after their diagnosis, treatment of patients with stage I melanoma in the vertical growth phase costs 50% more (95% CI 22-85%) than their counterparts with a radial growth pattern, resulting in an estimated absolute increase of € 256.23. Having a tumor thicker than 0.8 mm prompted an increase of 91% (95% CI 43-155%) in the costs (€955.24 in absolute terms). CONCLUSION Our data indicate a heterogeneity in the direct costs of stage I melanoma patients during the first year after diagnosis, which can be partly explained by clinical prognostic factors, like tumor thickness and growth pattern. New therapies for treating drug-resistant pneumococcal infections are urgently needed. The novel scaffold 6-hydroxy-4-oxo-1,2-dihydro-4H-quinoline was shown to have similar efficacies against all three different serotypes of S. pneumoniae, ATCC 49617™ (19F), ATCC BAA-1663™ (15B), and ATCC 700904™ (19A), in a resazurin-based high-throughput screen using the Korea Chemical Bank library. Further studies to identify a new lead with this scaffold, including tricyclic pyrrolo[3,2,1-ij]quinolone and pyrido[3,2,1-ij]quinolone derivatives, led to the identification of 6d, 7d and 12a. Compound 6d (IC50 = 0.92, 0.75, and 0.77 µM), 7d (IC50 = 0.57, 0.66, and 0.38 µM) and 12a (IC50 = 0.27, 1.03, and 0.62 µM) showed submicromolar IC50 values against 19F, 15B, and 19A, respectively, and thus serve as a starting point for further optimization. While some of compounds in this series exhibited acceptable pharmacokinetic profiles in preliminary in vivo rat experiments, the most active compound 12a showed poor solubility and high plasma protein binding. Our current research efforts are focused on optimizing compounds to improve physicochemical properties as well as potency. Hereditary predispositions are responsible for more than 30% of or paraganglioma. Their identification is essential to optimize medical care and to offer an appropriate screening to relatives. To date, there are more than 15 known paraganglioma/pheochromocytoma predisposing genes. The most frequently involved are those encoding the succinate dehydrogenase (SDHx), accounting for half of cases and the VHL gene, causing the Von Hippel Lindau syndrome and representing approximately 20% of genetically determined cases. Patients with SDHB genes mutations have a higher risk of metastatic disease. An oncogenetic counseling is recommended to all patients developing one or several paragangliomas, isolated or associated with other tumors. Apart from the clinical presentation and in particular the syndromic forms characterized by specific tumor spectra, there is no validated morphological criterion allowing to suspect a hereditary form. On the other hand, pathologists have now access to several immunohistochemical tools allowing the identification of some hereditary forms, in particular those linked to the SDHx, VHL and FH genes. Thus, the loss of expression in immunohistochemistry of the SDHB or FH proteins orientates respectively, towards SDHx and FH genes, while the membrane expression of carbonic anhydrase IX (CA-IX) is a sensitive and specific tool pointing towards a VHL anomaly. Other immunohistochemical markers are under evaluation. A systematic SDHB immunohistochemical staining is recommended on all paragangliomas/pheochromocytomas in order to allow an early detection of the most common hereditary forms and to contribute to the interpretation of the genetic results in these patients seen in oncogenetics consultation. Starch agricultural leftover is a potential substrate for photosynthetic bacteria to produce hydrogen. In this work, the effect of initial pH on photo-fermentation biohydrogen production process and electron balance were investigated. The modified Gompertz model was adopted, and hydrogen yield, sugar consumption and metabolite evolution were monitored with initial pH varying from 5 to 9. Results showed that hydrogen was produced mainly through acetic acid and butyric acid metabolism pathways when starch taken as carbon source. It was found that the maximum hydrogen yield (642 ± 22 mL) and highest hydrogen production rate (77.78 mL/(L·h)) were obtained at initial pH of 7. 37.65% substrates electrons diverted towards hydrogen. Lower hydrogen yield, hydrogen production rate and lower electrons diversion were obtained at other initial pH levels. Also, the lag phase time was 0.04 h when pH was 7, which was significantly lower than other levels.
