Objective: Bedside ultrasonography (US) is a new imaging modality that has begun to be used in the Pediatric Emergency Unit to evaluate inferior vena cava (IVC) diameter for intravascular volume status. In this article, we aimed to evaluate IVC diameter with bedside US before and after the fluid therapy in dehydrated children.
Methods: A total of 124 dehydrated patients were enrolled, aged 8 months to 17 years. The maximum diameters of the IVC and aorta (AO) were measured. IVC/AO ratio and IVC collapsibility index IVC-CI were calculated before and after the fluid therapy and correlation with the degree of dehydration and laboratory parameters was investigated.
Results: Of the 124 patients, 49.2% ( = 61) were male, the mean age was 7.5 ± 4.94 years. The IVC/AOs ratio was increased in mild and moderate/severe groups after fluid therapy compared to before fluid administration. While the mean rate of heart rate, blood urea nitrogen (BUN), creatinine, and uric acid values were higher in the moderate/severe group, potassium and HCO were lower. There was no significant change in AO diameter and IVC-CI after fluid therapy in all groups. When the factors affecting the IVC/AOs ratio were analyzed with the logistic regression backward model; the IVC/AO ratio was found to increase as the degree of dehydration decreased (Adj. = -0.318) and as the age (Adj. = 0.242) and CRP (Adj. = 0.186) value increased.
Conclusion: The IVC/AO ratio can be a promising index for the assessment and grading of dehydration in children, and cutoff values that vary according to age are necessary for a more objective assessment of dehydration.

Introduction-Aim: Spontaneous bacterial peritonitis (SBP) is a common complication in cirrhotic patients and is associated with a high mortality rate. The aim of this study is to determine the epidemiological and bacteriological profile of spontaneous bacterial peritonitis, as well as antibiotic resistance among hospitalized patients at CHU Mohammed VI, in order to guide empirical antibiotic choices for better management. Methods: This is a prospective study conducted over a period of 12 months, from January to December 2023, focusing on all requests for bacteriological examination of ascitic fluid samples.

Division of Division of Rhinology & Skull Base Surgery Department of Otolaryngology, University of Florida, Gainesville, Florida, USA.
Rationale: Smoking has been shown to be associated with circulating deficiencies in 25(OH)D3 and reduced sinonasal tissue levels of the active form of vitamin D, 1,25(OH)2D3. Given vitamin D's ability to reduce inflammation, we sought to examine if intranasal (IN) delivery of calcitriol [clinical analog of 1,25(OH)2D3] could reduce inflammation and improve disease severity in a murine model of chronic cigarette smoke-induced sinonasal inflammation (CS-SI).
Methods: Mice were exposed to CS 5 h/day, 5 days/week for 9 months, and then began IN calcitriol three times per week for 4 weeks.
Inhaled alpha-1 antitrypsin (AAT) restores lower respiratory tract protease-antiprotease homoeostasis and reduces inflammation in AAT-deficient individuals: a randomised phase 2 study.

Background: Alpha-1 antitrypsin (AAT)-deficient individuals have a greater risk for developing COPD than individuals with normal AAT levels.
Methods: This was a double-blind, randomised, parallel group, placebo-controlled trial to examine the safety and tolerability of "Kamada-AAT for Inhalation" (inhaled AAT) in subjects with AAT deficiency, and to explore its effect on AAT and biomarkers in the lung epithelial lining fluid (ELF). 36 patients with severe AAT deficiency were randomised 2:1 to receive 80 mg or 160 mg inhaled AAT or placebo once daily for 12 weeks.

Background: In cases of maternal primary infection with cytomegalovirus (CMV-MPI) maternal treatment with oral valaciclovir 8 g/day has been shown to reduce the risk of fetal infection. The pharmacological profile of this high dosage during pregnancy is not yet known.
Objectives: To quantify maternal-fetal exposure to valaciclovir 8 g/day in a population pharmacokinetic (popPK) study.
Asymptomatic lung abscess of aspergillus in a female without previous lung diseases or immunocompromise: a case report.

Background: Chronic pulmonary abscess usually results from bacterial or mycobacterium infection, but rarely from aspergillosis. Chronic pulmonary aspergillosis is usually found in a person with structural lung disease or immunocompromise. Here, we report a case of chronic lung abscess of aspergillosis without immunocompromise, structural lung diseases or even clinical symptoms.
