A Review Of Consanguinity In The Iraqi Population: A Call To Action To Prevent A Future Health Catastrophe, Zaid Ali Hawi, Kealan Pugsley, Atefeh Namipashaki, Walied Samarrai, Ziarih Hawi

Publications and Research

Although not uncommon worldwide, consanguinity has been a part of Arab culture and tradition as a means to strengthen tribal blood relations. However, this type of union has been linked to inherited diseases, particularly those of a recessive nature (e.g., hemoglobinopathies). Furthermore, several recent studies have documented highly significant associations between consanguineous parentage and common multifactorial diseases, including but not limited to hypertension, mental disorders, and several cardiovascular diseases. In Iraq, the prevalence of consanguinity is very high and still on the rise. This has resulted in an increased prevalence of inherited diseases and has significant negative impacts on Iraq’s …

Introduction: COVID-19 affects the hematologic system. This article evaluated the impact of hematologic involvement of different blood cell line parameters of white blood cells including absolute neutrophil count (ANC), hemoglobin, and platelets in COVID-19 patients and their association with hospital mortality and length of stay (LOS).

Methods: This was a retrospective study of 475 patients with con- firmed positive COVID-19 infection and hematologic abnormalities in the metropolitan New York City area.

Results: Elevated absolute neutrophil count (OR: 1.20; 95% CI: 1.02-1.42; p < 0.05) increased days of hematologic involvement (OR: 4.44; 95% CI: 1.42-13.90; p < 0.05), and persistence of hematologic involvement at discharge (OR: 2.87; 95% CI: 1.20-6.90; p < 0.05) was associated with higher mortality. Higher hemoglobin at admission (OR: 0.77; 95% CI:0.60-0.98; p < 0.001) and platelets peak (OR: 0.995; 95% CI: 0.992-0.997; p < 0.001) were associated with decreased mor- tality. Patients with higher white blood cell peak (B = 0.46; SE = 0.07; p < 0.001) and higher hemoglobin at admission (B = 0.05; SE = 0.01; p < 0.001) were associated with higher LOS. Those with higher hemo- globin nadir (B = -0.06; SE = 0.01; p < 0.001), higher platelets nadir (B = -0.001; SE = < 0.001; p < 0.001), and hematologic involvement at discharge or death (B = -0.06; SE = 0.03; p < 0.05) were associated with lower LOS.

Conclusions: These findings can be used by clinicians to better risk- stratify patients with hematologic involvement in COVID-19 …

Publications and Research

Acute ischemic stroke (AIS) is a common devastating disease that has increased yearly in absolute number of cases since 1990. While mechanical thrombectomy and tissue plasminogen activator (tPA) have proven to be effective treatments, their window-of-efficacy time is very short, leaving many patients with no viable treatment option. Over recent years there has been a growing interest in stimulating the facial nerves or ganglions to treat AIS. Pre-clinical studies have consistently demonstrated an increase in collateral blood flow (CBF) following ganglion stimulation, with positive indications in infarct size and neurological scores. Extensive human trials have focused on trans-oral electrical stimulation …

Publications and Research

Botanical therapeutics possess a unique potential in the treatment of viral diseases. The pharmacological base and clinical use of botanical therapeutics have been extensively reviewed. The mode of action(s) may be built either on the direct interference with the virus's ability to enter human cells, virus replication, or exerting immune-modulatory and anti-inflammatory effects. The adjuvant treatment with botanical therapeutics has the potential to result in advances in symptom resolution, decrease in disease burden and shortening its duration.

The gram-negative bacterium Vibrio cholerae is the causative agent of the diarrhoeal disease cholera and is responsible for seven recorded pandemics. Several factors are postulated to have led to the decline of 6th pandemic classical strains and the rise of El Tor biotype V. cholerae, establishing the current 7th pandemic. We investigated the ability of classical V. cholerae of the 2nd and 6th pandemics to engage their type six secretion system (T6SS) in microbial competition against non-pandemic and 7th pandemic strains. We report that classical V. cholerae underwent sequential mutations in T6SS genetic determinants that initially exposed 2nd pandemic strains …

Publications and Research

Alzheimer’s Disease (AD), the most common type of dementia, is a neurodegenerative disease characterized by plaques of amyloid-beta (Aβ) peptides found in the cerebral cortex of the brain. The pathological mechanism by which Aβ aggregation leads to neurodegeneration remains unknown. Interestingly, genetic mutations do not explain most AD cases suggesting that other mechanisms are at play. Epigenetic mechanisms, such as histone post-translational modifications (PTMs), may provide insight into the development of AD. Here, we exploit a yeast Aβ overexpression model to map out the histone PTM landscape associated with AD. We find a modest decrease in the acetylation levels on …

Intangible Cultural Heritage: A Benefit To Climate-Displaced And Host Communities, Gül Aktürk, Martha B. Lerski

Publications and Research

Climate change is borderless, and its impacts are not shared equally by all communities. It causes an imbalance between people by creating a more desirable living environment for some societies while erasing settlements and shelters of some others. Due to floods, sea level rise, destructive storms, drought, and slow-onset factors such as salinization of water and soil, people lose their lands, homes, and natural resources. Catastrophic events force people to move voluntarily or involuntarily. The relocation of communities is a debatable climate adaptation measure which requires utmost care with human rights, ethics, and psychological well-being of individuals upon the issues …

Vascular calcification predicts atherosclerotic plaque rupture and cardiovascular events. Retrospective studies of women taking bisphosphonates (BiPs), a proposed therapy for vascular calcification, showed that BiPs paradoxically increased morbidity in patients with prior acute cardiovascular events but decreased mortality in event-free patients. Calcifying extracellular vesicles (EVs), released by cells within atherosclerotic plaques, aggregate and nucleate calcification. We hypothesized that BiPs block EV aggregation and modify existing mineral growth, potentially altering microcalcification morphology and the risk of plaque rupture. Three-dimensional (3D) collagen hydrogels incubated with calcifying EVs were used to mimic fibrous cap calcification in vitro, while an ApoE−/− mouse was used …

When The Pandemic Opts For The Lockdown: Secretion System Evolution In The Cholera Bacterium, Francis J. Santoriello, Stefan Pukatzki

Publications and Research

Vibrio cholerae, the causative agent of the diarrheal disease cholera, is a microbe capable of inhabiting two different ecosystems: chitinous surfaces in brackish, estuarine waters and the epithelial lining of the human gastrointestinal tract. V. cholerae defends against competitive microorganisms with a contact-dependent, contractile killing machine called the type VI secretion system (T6SS) in each of these niches. The T6SS resembles an inverted T4 bacteriophage tail and is used to deliver toxic effector proteins into neighboring cells. Pandemic strains of V. cholerae encode a unique set of T6SS effector proteins, which may play a role in pathogenesis or pandemic …

Publications and Research

Bisphosphonates (BPs) are a mainstay of osteoporosis treatment; however, concerns about bone health based on oversuppression of remodeling remain. Long-term bone remodeling suppression adversely affects bone material properties with microdamage accumulation and reduced fracture toughness in animals and increases in matrix mineralization and atypical femur fractures in patients. Although a “drug holiday” from BPs to restore remodeling and improve bone quality seems reasonable, clinical BPs have long functional half-lives because of their high hydroxyapatite (HAP) binding affinities. This places a practical limit on the reversibility and effectiveness of a drug holiday. BPs with low HAP affinity and strong osteoclast inhibition …
