Hydatidosis; is a zoonotic disease caused by Echinococcus granulosus and characterized by
infiltration of inflammatory cells. This study was investigated the hematological and
histopathological changes in the hearts of rats injected with protoscoleces. Rats were injected
with protoscoleces collected from either liver of sheep, goats, and cows (from the abattoir of
Al-Muthanna province, south of Iraq) or isolated from infected humans from Al-Hussein
Teaching Hospital. Sheep protoscoleces showed a significant increase of lymphocytes that
refer to the induction of a high response of the immune system in rats. The numbers of WBC,
RBCs, and platelets were generally increased in rats injected with protoscoleces isolated
from sheep and goats. These changes could refer to the activation of defense mechanisms
against the hydatid injected materials. However, the levels of MCV, MCH, MCHC, MPV and
PDW were less than normal values. Heart sections of rats injected with protoscoleces isolated
from humans showed clear histological changes. While TSP, TGP and TCP exhibited variant
histopathological changes such as infiltration of inflammatory cells, pink glass appearance
and congestion of arteries. Thus, these alterations can be considered as additional evidence
of how the immune response reacts against the injected materials in the heart.

Understanding the normal physiology of the body is the key to study the changes that occur due to any
infection. It is known that enteric infections play a considerable role in affecting normal body status.
Thus, this study was designed for investigating the enteric infections in Arabian camels in Al-Muthanna
Province. In this investigation, 588 fecal and blood serum samples (for diarrheic camels only) were
collected from the camels in different areas of Al-Muthanna Province, Iraq from both sexes of different
ages during the period from October 2020 up to the end of August 2021. The samples were examined
using routine microscopic examination techniques, hematological techniques, and ELISA for parasitic
and viral identification. Eimeria rajasthani, Isospora orlovi were recorded for the first time in Iraqi
camels with clinical signs of diarrhea, dehydration, and emaciation. The study recorded four types of
protozoa: Eimeria spp., Isospora, Cryptosporidium and Balantidium coli. The recorded types of Eimeria
were E. dromedarii, E. cameli, and E. rajasthani. There was a significant effect of age on infection rates
with Eimeria spp. as the highest Eimeria ratio was in ages of less than two years animals. The infection
rates were also affected with months which reached the highest ratios of Eimeria in October while the
lowest ratio of Eimeria was recorded in July. BVDV infection rate was found in camels that suffered from
diarrhea. There is no significant effect of sex on the onset of the viral disease in camels. For hematological
parameters, there were significant differences in RBCs, WBCs, Hb, and PCV values in protozoal and BVDV
infections. In conclusion, different kinds of protozoal and viral infections were recorded. Some of the
recorded infections were associated with acute clinical signs and have zoonotic importance.

The aim of this study was to study the genotype of a hospital collection of Group B
Streptococcus (GBS) from invasive and non-invasive sites. Fifty-one pre-characterised human
of GBS were re-identified and further analysed by multilocus sequence typing (MLST) in relation
to previously published serotypes. Fifteen sequence types (ST) were found with ST1 being the
most predominant. ST1 was also associated with majority of the invasive isolates. The genotypic
distribution patterns of GBS in this study were largely in agreement with previous reports from
other countries indicating the tendency of certain genotypes to prevail in human infection settings.

Diabetes mellitus is associated with inadequate bone health and quality and heightened susceptibility to fractures, even in patients with normal or elevated bone mineral density. Elevated advanced glycation end-products (AGEs) and a suppressed incretin pathway are among the mechanisms through which diabetes affects the bone. Accordingly, the present review aimed to investigate the effects of antidiabetic medications on bone quality, primarily through AGEs and the incretin pathway. Google Scholar, Cochrane Library, and PubMed were used to examine related studies until February 2024. Antidiabetic medications influence AGEs and the incretin pathway directly or indirectly. Certain antidiabetic drugs including metformin, glucagon-like peptide-1 receptor agonists (GLP-1RA), dipeptidyl-peptidase-4 (DDP-4) inhibitors, α-glucosidase inhibitors (AGIs), sodium-glucose co-transporter-2 inhibitors, and thiazolidinediones (TZDs), directly affect AGEs through multiple mechanisms. These mechanisms include decreasing the formation of AGEs and the expression of AGEs receptor (RAGE) in tissue and increasing serum soluble RAGE levels, resulting in the reduced action of AGEs. Similarly, metformin, GLP-1RA, DDP-4 inhibitors, AGIs, and TZDs may enhance incretin hormones directly by increasing their production or suppressing their metabolism. Additionally, these medications could influence AGEs and the incretin pathway indirectly by enhancing glycemic control. In contrast, sulfonylureas have not demonstrated any obvious effects on AGEs or the incretin pathway. Considering their favorable effects on AGEs and the incretin pathway, a suitable selection of antidiabetic drugs may facilitate more protective effects on the bone in diabetic patients.

Local malaria transmission in the United Arab Emirates (UAE) came to an end in 1997. Nevertheless, UAE has been subjected to substantial importation of malaria cases from abroad, concerning both UAE nationals and immigrants from malarious countries with a total number of 2,119 cases in 2007. To evaluate a new DNA extraction technique using nested PCR, blood samples were collected from 132 individuals who presented to Infectious Diseases Department in Rashid Hospital, Dubai, and Central Department of Malaria Control with fever and persistent headache. Giemsa-stained blood films and ELISA test for malaria antibodies were carried out for detection of Plasmodium infection. Plasmodium infections were identified with the genus-specific primer set and species differentiation using nested PCR. A rapid procedure for diagnosis of malaria infections directly from dried blood spots using for the first time DNA extract from FTA Elute cards was evaluated in contrast to extraction techniques using FTA classic cards and rapid boiling technique. Our new simple technique for DNA extraction using FTA Elute cards was very sensitive giving a sensitivity of 100% compared to 94% using FTA classic cards and 62% in the rapid boiling technique. No complex preparation of blood samples was required prior to the amplification. The production cost of DNA isolation in our PCR assay was much less in comparable to that of other DNA extraction protocols. The nested PCR detected plasmodial infection and could differentiate P. falciparum from P. vivax, and also detected the mixed infection.

Objectives:
Fatigue is the most frequently reported symptom experienced by cancer patients and has a profound effect on their quality of life (QOL). The study aimed to determine the impact of fatigue on QOL among breast cancer patients receiving chemotherapy and to identify the risk factors associated with severe fatigue incidence.
Methods:
This was an observational prospective study carried out at multiple centers. In total, 172 breast cancer patients were included. The Functional Assessment of Chronic Illness Therapy-Fatigue Questionnaire was used to measure QOL, while the Brief Fatigue Inventory (BFI) was used to assess the severity of fatigue.
Results:
The total average mean and standard deviation of QOL were 84.58±18.07 and 4.65±1.14 for BFI scores, respectively. A significant association between fatigue and QOL was found in linear and multiple regression analyses. The relationships between fatigue severity and cancer stage, chemotherapy dose delay, dose reduction, chemotherapy regimen, and ethnicity were determined using binary logistic regression analysis.
Conclusion
The findings of this study are believed to be useful for helping oncologists effectively evaluate, monitor, and treat fatigue related to QOL changes.
