ABSTRACT

Due to political conflict, insurgency, and the COVID-19, the number of displaced households in need of humanitarian support in Iraq has increased. This study investigated factors related to desire of displaced households to receive humanitarian information. Data from the eighth round of the Iraq Multi-Cluster Needs Assessment was used. We classified the household displacement status, identifying levels and types of humanitarian information that the households sought, together with whether the households were impacted by COVID-19. We identified safety and security, housing, water and electricity services, education, health care, and levels of humanitarian assistance resulted in significant differences between internally displaced person (IDP) and returnee households in terms of interest in receiving humanitarian information. The desire to receive humanitarian information was related to whether household members were unemployed due to COVID-19, displacement status, and walking time to reach the nearest health care facility and marketplace. Returnees and IDPs in Iraq are facing a new crisis. Their individual, structural, and environmental vulnerabilities are increasing commensurately. New strategies such as strategies using online or mobile communication that provide humanitarian information are needed to provide humanitarian information to vulnerable groups such as those who have lost jobs due to COVID-19, female heads of households, and those with health problems. In addition to traditional cash and voucher support, the use of the latest technologies such as smartphones and mobile clinics in humanitarian settings would be new strategies.

ABSTRACT

OBJECTIVES: The purpose of this study was to evaluate a partially purified extract (elm extract) from the Ulmi cortex (Ulmi macrocarpa Hance) and its active ingredient, a mix of procyanidin oligomers (3 to 12 flavan-3-ol monomers, an average molecular weight of 1,518 with an average polymerization degree of 5.3) for a possible inhibitory effect against proteases. BACKGROUND: Host-derived matrix metalloproteinases (MMPs) and bacterial proteases play important roles in the gingival tissue destruction that is a characteristic of periodontitis. The inhibitors of these proteases may be developed into therapeutic agents against periodontitis. METHODS: The inhibitory effects were assessed by gelatin zymography. The MMPs tested were originated from the gingival crevicular fluid (GCF) of adult periodontitis patients and from the conditioned media of cultured periodontal ligament (PDL) cells, which provided the proMMP-2 and activated MMP-2 when treated with a periodontopathogen, Treponema lecithinolyticum. Bacterial enzymes tested were secreted forms from two major periodontopathogens, Porphyromonas gingivalis and Treponema denticola. In addition, the inhibitory effects on trypsin-like enzymes from these two periodontopathogens were assayed by the n-benzoyl-DL-arginine-naphthylamide (BANA) test. RESULTS: The elm extract and the procyanidin oligomer (100-1,000 microg/ml) exhibited potent inhibitory effects on the MMPs in GCF (chiefly MMP-8 and MMP-9), the pro and active forms of MMP-2, and secreted and trypsin-like enzymes from T. denticola and P. gingivalis. CONCLUSIONS: These results suggest that elm cortex should be considered as a potential agent against periodontal diseases, due to its inhibitory action on MMPs and the proteases of periodontopathogens.
