Objective: Sponges (phylum Porifera) are sessile marine invertebrates and are known to be the richest source of pharmacologically-active compounds. This work was taken to investigate the antibacterial, antifungal activity and cytotoxicity from marine sponge. Method: In this study the marine sponge Spongosorites halichondrioides crude extracts were investigated for three bioassays. The first is an antimicrobial test against Proteus vulgaris, Bacillus subtilis, Staphylococcus aureus, Salmonella typhi, Klebsiella pneumonia, Escherichia coli, P. aeruginosa and the second is an antifungal test against three pathogenic fungi, Aspergillus flavus, Aspergillusniger and Metarhizium anisopliae. The third is a cytotoxicity test using larva of Artemia salina, for detection of cytotoxic activity in the extracts. Result: For all the three bioassays, extracts were found to be bioactive. This result suggests that this marine sponge is able to produce biologically active agents required for an overall defense against their predators. Conclusions: Further GC MS was done and the fragmentation pattern, showed the presence of sterol esters and terpenoids in the active extracts.

Background/Aims:
We aim to assess the influence of obesity on gastroparesis (GP) hospitalizations in the United States (US).
Methods:
The National Inpatient Sample was analyzed from 2007-2017 to identify all adult hospitalizations with a primary discharge diagnosis of GP. They were subdivided based on the presence or absence of obesity (body mass index > 30). Hospitalization characteristics, procedural differences, all-cause inpatient mortality, mean length of stay (LOS), and mean total hospital charge (THC) were identified and compared.
Results:
From 2007-2017, there were 140 293 obese GP hospitalizations accounting for 13.75% of all GP hospitalizations in the US. Obese GP hospitalizations were predominantly female (76.11% vs 64.36%, P < 0.001) and slightly older (51.9 years vs 50.8 years, P < 0.001) compared to the non-obese cohort. Racial disparities were noted as Blacks (25.49% vs 22%, P < 0.001) had higher proportions of GP hospitalizations with obesity compared to the non-obese cohort. Furthermore, we noted higher rates of inpatient upper endoscopy utilization (6.05% vs 5.42%, P < 0.001), longer mean LOS (5.71 days vs 5.32 days, P < 0.001), and higher mean THC ($53 373 vs $45 040, P < 0.001) for obese GP hospitalizations compared to the non-obese group. However, obese GP hospitalizations had lower rates of inpatient mortality (0.92% vs 1.33%, P < 0.001), and need for nutritional support with endoscopic jejunostomy (0.25 vs 0.56%, P < 0.001) and total parenteral nutrition (1.46% vs 2.33%, P < 0.001) compared to the non-obese cohort.
Conclusions
In the US, compared to non-obese, a higher proportion of obese GP hospitalizations were female and Blacks. Obese GP hospitalizations also had higher THC, LOS, and rates of upper endoscopy.

The study aimed to compare and correlate serum levels of IL-6, 10, and 25-hydroxycholecalciferol
in individuals with asthma with and without post-COVID condition (PCC). The study was designed
to investigate the inflammatory response and serum 25-hydroxycholecalciferol status in asthmatics
with and without PCC. A cross-sectional study of 252 subjects (128 asthmatics and 124 non-asthmatic
subjects) was carried out. Interleukins and 25-hydroxycholecalciferol levels were estimated on ELISA.
The principle findings were that IL-6 and 25-hydroxycholecalciferol levels were significantly increased
(p<0.001), while IL-10 levels were non-significant in asthmatics with PCC compared to those without PCC.
However, 25-hydroxycholecalciferol levels were significantly increased, but no significant change was
observed in IL-6, and IL-10 levels in non-asthmatics with and without chronic PCC. A significant positive
correlation (r = 0.258) was found between 25-hydroxycholecalciferol and IL-6 but a significant negative
correlation (r = -0.227) with IL-10 in asthmatics with PCC. Similarly, a significant negative correlation (r
= -0.285) was found between 25-hydroxycholecalciferol and IL-10 but was non-significant with IL-6 in
asthmatics without PCC. The correlation of 25-hydroxycholecalciferol with IL-10 was significant (0.683),
but IL-6 was non-significant in non-asthmatics with PCC. Multiple regression analysis showed that age,
IL-6, gender, and PCC were significantly related in adjusted values to 25-hydroxycholecalciferol. This
study sheds light on the complex liaison between 25-hydroxycholecalciferol levels and inflammatory
responses in asthmatics, especially those with PCC. The findings suggest that although asthmatics with
PCC maintain sufficient levels of 25-hydroxycholecalciferol, they show a substantial increase in the proinflammatory response. This suggests that PCC exacerbates the pro-inflammatory response in asthma.
Moreover, the study reveals that asthmatics, whether with or without PCC, display a negative correlation
between 25-hydroxycholecalciferol and the anti-inflammatory response. This emphasizes the main
influence of asthma on the overall inflammatory response. These findings reveal a complex interplay
between vitamin D levels and inflammatory mediators in asthmatic individuals with and without PCC.
