Hemoglobinopathies are major health problems among Iraqi Kurds, who are a distinct ethnic group inhabiting North and Northeastern Iraq. We reviewed published literature on these disorders in this part of the world, and it was revealed that the most prevalent is β-thalassemia with carrier rates of 3.7-6.9%. Alpha thalassemia is less prevalent with carrier rates of 0.03-1.22%, while the sickle cell gene is variably distributed with carrier rates of 0.06-1.2%. Other structural hemoglobinopathies and δβ-thalassemia are sporadic. selleck Twenty-seven different β-thalassemia mutations were identified, with seven constituting 82% of 1039 chromosomes characterized, namely IVS-II-1 (G>A), IVS-I-6 (T>C), IVS-I-I (G>A), codon 8 (-AA), codon 8/9 (+G), IVS-I-110 (G>A), and codon 5 (-CT). There were notable regional variations in the distribution of β-thalassemia mutations, with Cd44 being mainly prevalent in the North, while IVS-I-110 is mainly prevalent in the East. In relevance to α-thalassemia, ten different mutations were detected, with the four most frequent constituting 92.4% of 262 alleles characterized being -α3.7, --MED, α-5ntα, and αPolyA1α. In relevance to sickle cell gene, it is seen in the northern part of the region bordering Turkey, with comparable prevalence rates, and is associated, similar to Turkey, mainly with the Benin haplotype, unlike that in Southern Iraq where it is associated with the Arab-Indian haplotype, similar to Eastern Arabian Peninsula. Given the high prevalence of hemoglobinopathies in the region, and the high rates of consanguineous marriages, a preventive program was initiated in 2008, and results of its first 5 years were promising, though there are still many outstanding challenges that require addressing.Hereditary hemoglobin disorders are among the most common inherited diseases globally. In Oman, the burden of hereditary hemoglobin disorders has long been recognized as a major public health problem. In Oman, the prevalence of SCD ranges between 0.2 and 0.3% and of homozygous B-thalassemia was 0.07-0.08% while the prevalence of sickle cell trait and B-thalassemia trait reached up to 4.8-6% and 2-2.6% respectively. Glucose-6-phosphate dehydrogenase (G6PD) had a high prevalence in Oman, being 25% in males and 10% in females. The premarital screening and counseling (PMSC) program is an important preventative service for the most common hereditary hemoglobin disorders in Oman. The aim of this research is to study the attitude of those with abnormal premarital screening results and the impact of these results. This cross-sectional study was carried out in all primary healthcare centers in the Muscat governorate in 2018 to analyze abnormal premarital screening (PMS) tests results which mainly include sickle cell d is needed to raise public awareness regarding early PMS. Additionally, further genetic counseling before and after PMS testing is essential for the program's success.The dual inhibition of adenosine receptors A1 (A1 AR) and A2 (A2A AR) has been considered as an efficient strategy in the treatment of Parkinson's disease (PD). This led to the recent development of a series of methoxy-substituted benzofuran derivatives among which compound 3j exhibited dual-inhibitory potencies in the micromolar range. Therefore, in this study, we seek to resolve the mechanisms by which this novel compound elicits its selective dual targeting against A1 AR and A2A AR. Unique to the binding of 3j in both proteins, from our findings, is the ring-ring interaction elicited by A1Phe275 (→ A2Phe170) with the benzofuran ring of the compound. As observed, this π-stacking interaction contributes notably to the stability of 3j at the active sites of A1 and A2A AR. Besides, conserved active site residues in the proteins such as A1Ala170 (→ A2Ala65), A1Ile173 (→ A2Ile68), A1Val191 (→ A2Val86), A1Leu192 (→ A2Leu87), A1Ala195 (→ A2Ala90), A1Met284 (→ A2Met179), A1Tyr375 (→ A2Tyr369), A1Ile378 (→ A2Ile372), and A1His382 (→ A2His376) were commonly involved with other ring substituents which further complement the dual binding and stability of 3j. This reflects a similar interaction mechanism that involved aromatic (π) interactions. Consequentially, vdW energies contributed immensely to the dual binding of the compound, which culminated in high ΔGbinds that were homogenous in both proteins. Furthermore, 3j commonly disrupted the stable and compact conformation of A1 and A2A AR, coupled with their active sites where Cα deviations were relatively high. Ligand mobility analysis also revealed that both compounds exhibited a similar motion pattern at the active site of the proteins relative to their optimal dual binding. We believe that findings from this study with significantly aid the structure-based design of highly selective dual-inhibitors of A1 and A2A AR.While survival for children with hypoplastic left heart syndrome (HLHS) has improved, compromised cardiac output and oxygen delivery persist, and children show cognitive deficits. Most research has assessed young children on broad cognitive indices; less is known about specific indices in older youth. In this pilot study, cognitive function and attention in youth ages 8 to 16 years with HLHS (n = 20) was assessed with the Wechsler Intelligence Scale for Children - Fifth Edition (WISC-V) and NIH Toolbox Cognition Battery (NTCB); parents completed the Child Behavior Checklist. Children scored significantly lower than normative means on the WISC-V Full Scale IQ, Verbal Comprehension, Visual Spatial, Working Memory, and Processing Speed indices, and the NTCB Fluid Cognition Composite; effect sizes ranged from medium to large. Attention problems had a large significant effect. Child age corresponded to lower visual spatial scores. Findings highlight the importance of assessing multiple cognitive indices for targeted intervention and investigating age and disease factors as potential correlates in larger samples.
Clinical Treatment Score at 5years (CTS5) is a prognostic tool to estimate distant recurrence (DR) risk after 5years of endocrine therapy for postmenopausal women with oestrogen receptor-positive (ER-positive) breast cancer.

The validity of CTS5 was tested in a retrospective cohort of patients diagnosed with early ER-positive breast cancer. The primary endpoint was DR in years 5-10. The primary analysis cohort consisted of postmenopausal women, with premenopausal women as a secondary analysis cohort. Cox regression models were used to determine the prognostic value of CTS5 and Kaplan-Meier curves were used with associated 10-year DR risks (%).

2428 women were included with a median follow-up of 13.4years. The CTS5 was significantly prognostic in both postmenopausal (N=1662, HR =2.18 95% CI (1.78-2.67)) and premenopausal women (N=766, HR =1.84 95% CI (1.32-2.56)). The 10-year DR risks were 2.9% (1.9-4.5), 7.2% (5.3-9.9), and 12.9% (10.0-16.7) for low, intermediate and high risk in postmenopausal women and 3.
