Abstract
Background: In the present study, we hypothesized that conditioned medium (CM) derived from mesenchymal stem cells attenuates the brain oxidative stress in sepsis induced by the cecal ligation and puncture (CLP) model.
Methods: This study was performed in the Department of Physiology at Tehran University of Medical Sciences from August 2018 to April 2019. Conditioned medium was collected from mesenchymal stem cells isolated from rat's adipose tissues at the second culture passage. Male Wistar rats weighting (220-250 g) were randomly divided into three experimental groups (n=8 each): Sham, Sepsis and CM. Sepsis was induced by cecal ligation and puncture model in the Sepsis and CM groups. Animals in the CM group received the conditioned medium from 5×105 mesenchymal stem cells (2 h after sepsis induction, i. p., 3-5 mL). The systolic blood pressure and O2 saturation were measured 24 h after the treatment. The plasma and brain tissue samples were taken for inflammatory and oxidative stress assessment, respectively.
Results: Septic rats showed a significantly lower systolic blood pressure and O2 saturation level. They also had a significant increase in the plasma inflammatory indices (tumor necrosis factor-alpha [TNF-α], interleukin-6 [IL-6]) and brain malondialdehyde (MDA) content as well as a significant reduction in the brain superoxide dismutase (SOD) activity compared to the Sham group. The CM group had significantly higher systolic blood pressure and O2 saturation level compared to the septic rats. The animals in the CM group showed a significant attenuation in the plasma inflammatory indices (TNF-α and IL-6) and brain MDA content while having a significantly higher brain SOD activity compared to the Sepsis group.
Conclusion: Our findings showed that conditioned medium derived from mesenchymal stem cells has protective effects in preventing the inflammatory and oxidative stress status and may be suggested as a promising treatment in patients suffering from sepsis and septic shock.

Abstract
Background: Neonatal sepsis is a severe systemic bacterial infection that affects on premature neonates prognosis. Therefore, the aim of this study was to evaluate the short-term prognosis of neonate's infection.
Methods: The present study is a cross-sectional study that was performed on 729 neonates suspected of infection, in neonatal ward in Ghaem Hospital of Mashhad since May 2015 to May 2022 by available sampling. The data collection tool was a researcher-made checklist containing neonatal characteristics (gestational age, birth weight, first and fifth minute Apgar score, and neonatal status at discharge) and laboratory information (White Blood Cell, Platelet (PLT), C-reactive Protein, Blood culture, Cerebrospinal fluid culture). Infants with congenital infection, congenital anomaly and positive blood cultures without clinical and laboratory symptoms were excluded from the study. Neonatal prognosis was compared in terms of death or discharge among neonates with and without definitive infection. First, we described the results using statistical tables and graphs, and then, data were analyzed by Kolmogorov-Smirnov, T test and SPSS software, version 26 (IBM SPSS, Armonk, NY, USA). P<0.05 considered as significant.
Results: According to the results of this study, low birth weight and lower gestational age and lower Apgar score increase the risk of neonatal death. About one-fifth of infants died of definitive infection. The cases of death due to infection in the group of deceased infants were about 4 times higher than in the group of discharged infants. About one third of the babies with sepsis and half of the babies with meningitis died. Forty-four percent of infants with early sepsis and 40% of infants with late sepsis died. In cases of neonatal death due to sepsis, the most common gram-negative infectious agent was Acinetobacter and the most common gram-positive infectious agent was Enterococcus.
Conclusion: Neonatal definitive infection worsens their prognosis. So, the risk of neonatal death increases by 5 times. The probability of death in meningitis is more than sepsis and in early sepsis is more than late sepsis and in sepsis due to gram-negative is more than gram-positive.

Abstract
Background: One of the major challenges in intensive care unit (ICU) patients is sepsis. The incidence of sepsis in patients admitted to the ICU has been reported from 13.6-39.3%. Many factors affect patient mortality, including acute phase proteins such as albumin.
Methods: The present study was a retrospective study in which patients with a diagnosis of sepsis referred to Golestan Hospital in Ahvaz from March to August were collected. In the present study, patients with sepsis admitted to the ICU who did not show improvement for more than 7 days were evaluated for length of hospital stay, survival and the relationship with albumin levels. During the study, albumin was checked every 72 hours and its validation was done. Based on albumin levels less than 2.6, they were treated with albumin. The patients who did not have an increase in the level of albumin remained in the study.
Results: 124 patients including 64 women (51.6) and 60 men (48.4) with a mean age of 66.4±15.4 were included in the study. The mean duration of hospitalization was 31.4±18.9 days, in which 24 patients (19.4%) died and 100 patients (80.6%) were discharged. Age, albumin and protein levels were associated with disease prognosis (P<0.001). Also, the duration of hospitalization in the deceased patients was longer than the recovered patients (27.7±25 vs. 32±17.1) (P=0.04). After further investigations, it was found that there is no difference between the deceased people (66±15.7) and the recovered people (67.7±14.1) (P=0.7).
Conclusion: The results of the present study showed that albumin has a direct effect on the severity of sepsis and this issue affects older patients more. Therefore, it is recommended that albumin be considered as a risk factor and one of the influential factors in choosing the best treatment strategy, which is associated with a reduction in mortality, hospitalization and treatment costs.
