The annual reproduction cycle of gilt sardine, Sardinella aurita, based on gonad maturity stages, gonad weight and gonadosomatic index was the subject of this study. A total of 2033 gilt sardines (983 males, 1021 females and 29 undetermined) were analysed. Fish were collected monthly from commercial purse seiners between November 2007 and January 2009 in the eastern middle Adriatic Sea (mesh size 8 mm/bar length/;sampling: five boats per month). Based on the monthly evolution of gonad maturation stages, gonad weights and gonadosomatic index, the peak spawning season was determined to be from June to August. Variations in sea surface temperature (SST) coincided with monthly variations of the gonadosomatic index. Highest monthly average values for both analysed parameters were recorded in July (GSI = 3.38;T = 26.5 degrees C). Fifty per cent (L-50) of males and females reached sexual maturity at TL 15.8 cm and at 16.6 cm, respectively. Absolute fecundity ranged from 8458 to 48 032 (mean 34 565 +/- 10 310), whereas relative fecundity was from 171 to 722 (mean 385 +/- 104.35). Mean value of the oocyte size was 0.53 +/- 0.10 mm.

Background. Disruption of the endothelial glycocalyx (EG) is associated with a poor prognosis in various clinical settings. This study aimed to determine the association between immediate postoperative serum syndecan-1 levels, a representative marker for EG degradation, and major postoperative morbidity and mortality in patients undergoing robot-assisted esophagectomy. Methods. Patients who underwent robot-assisted esophagectomy between 2018 and 2022 were prospectively enrolled. The primary outcome was the association between immediate postoperative syndecan-1 levels and the occurrence of major postoperative morbidity and mortality within 30 days of surgery. Patients were classified into low and high syndecan-1 groups based on the optimal cut- off value of syndecan-1 for predicting major morbidity and mortality. A multivariable logistic regression analysis was performed to investigate the risk factors for major morbidity and mortality. Results. A total of 207 patients were analyzed. Patients with high syndecan-1 levels (>= 48 ng/mL) showed a significantly greater incidence of unexpected returns to the operating room and anastomotic leaks and longer durations of hospital and intensive care unit stays than patients with low syndecan-1 levels (<48 ng/mL). Immediate postoperative syndecan-1 levels >= 48 ng/mL ( odds ratio [OR] 2.32, 95% confidence interval [ CI] 1.23-4.76), American Society of Anesthesiologists physical status >= III (OR 3.36, 95% CI 1.56-7.22), and current smoker (OR 4.02, 95% CI 1.5210.61) were independently associated with major morbidity and mortality within 30 days of esophagectomy. Conclusions. Immediate postoperative syndecan-1 levels >= 48 ng/mL could be used for the early detection of patients at high risk of complications after robot-assisted esophagectomy.
