Radioulnar synostosis (RUS) is a rare, congenital bone anomaly characterized by fusion of the radius and the ulna. RUS occurs more often in males than in females and is bilateral in 50% of the cases. More than 400 cases of RUS have been described since 1793. In the literature, seven cases with RUS and hematologic problems were reported, including the newly named radioulnar synostosis-hematology syndrome. Globally, this is the first reported case of RUS associated with malignancy, that is, acute lymphoblastic leukemia, in a 3-year-old male child.

Essentials Cancer patients receiving anticoagulants for venous thromboembolism have an elevated bleeding risk. This secondary analysis of CATCH assessed characteristics of clinically relevant bleeding (CRB). CRB occurs in 15% of cancer patients with thrombosis using therapeutic doses of anticoagulation. After multivariate analysis, risk factors for CRB were age >75 years and intracranial malignancy. Summary Background Cancer patients with acute venous thromboembolism (VTE) receiving anticoagulant treatment have an increased bleeding risk. Objectives We performed a prespecified secondary analysis of the randomized, open-label, Phase III CATCH trial (NCT01130025) to assess the rate and sites of and the risk factors for clinically relevant bleeding (CRB). Patients/Methods Patients with active cancer and acute, symptomatic VTE received either tinzaparin 175 IU kg-1 once daily or warfarin (target International Normalized Ratio [INR] of 2.0-3.0) for 6 months. Fisher's exact test was used to screen prespecified clinical risk factors; those identified as being significantly associated with an increased risk of CRB then underwent competing risk regression analysis of time to first CRB. Results Among 900 randomized patients, 138 (15.3%) had 180 CRB events. CRB occurred in 60 patients (81 events) in the tinzaparin group and in 78 patients (99 events) in the warfarin group (hazard ratio [HR] 0.64; 95% confidence interval [CI] 0.45-0.89). Common bleeding sites were gastrointestinal (36.7%; n = 66), genitourinary (22.8%; n = 41), and nasal (10.0%; n = 18). In multivariate analysis, the risk of CRB increased with age > 75 years (HR 1.83, 95% CI 1.14-2.94) and intracranial malignancy (HR 1.97, 95% CI 1.07-3.62). In the warfarin group, 40.4% of CRB events occurred in patients with with an INR of 75 years and intracranial malignancy.

- Abstract
The Middle Eastern prevalence of sickle cell anemia, a genetic disorder that affects red blood cells, necessitates additional research. On a molecular level, we sought to identify and sort the oral microbiota of healthy individuals and those with sickle cell anemia. Furthermore, it is crucial to comprehend how changes in the genetic makeup of the oral microbiota impact the state of sickle cell anemia. Using next-generation sequencing, the 16S rRNA amplicon was examined using saliva samples from 36 individuals with sickle cell anemia and healthy individuals. These samples were obtained from sickle cell anemia patients (18 samples) and healthy control participants (controls, 18 samples). Various analyses are conducted using bioinformatic techniques to identify distinct species and their relative abundance. Streptococcus , followed by Fusobacterium nucleatum , Prevotella , and Veillonella were the most prevalent genera of bacteria in the saliva of the SCA and non-SCA individuals according to our findings. Rothia mucilaginosa , Prevotella scoposa , and Veillonella dispar species were the dominant species in both sickle cell anemia and non-sickle cell anemia subjects. Streptococcus salivarius , Actinomyces graevenitzii , Actinomyces odontolyticus , and Actinomyces georgiae spp. were the most prevalent bacterial spp. in the studied SCA cases. The sequencing of the 16S rRNA gene yielded relative abundance values that were visualized through a heatmap analysis. Alterations in the oral microflora's constitution can significantly affect the susceptibility of sickle cell anemia patients to develop more severe health complications. Salivary diagnosis is a potential tool for predicting and preventing oral microbiome-related diseases in the future.

- Abstract
Background: It is well-established that specific herbal plants contain natural active ingredients that have demonstrated anti-cancer potential. Therefore, they are considered highly beneficial as a potential adjuvant, alternative or complementary agent in anti-cancer therapy. However, the low chemical stability and limited bioavailability of 3, 3'-Diindolylmethane (DIM), a plant-derived compound used in clinical settings, limit its therapeutic applications. To overcome this challenge, researchers have focused on developing innovative approaches to improve DIM's biological activity, such as utilizing nanoformulations. Here, we investigated the potential benefits of coating DIM nanoparticles (DIM-NPs) with PEG/chitosan in the treatment of breast cancer. Our results demonstrate the molecular mechanism underlying the activity of DIM-NPs, highlighting their potential as an effective therapeutic strategy for breast cancer treatment., Methods: DIM-PLGA-PEG/chitosan NPs were synthesised and characterised using dynamic light scattering (DLS) and evaluated the impact of these NPs on two breast cancer cell models., Results: DIM-NPs had an average diameter of 102.3 nm and a PDI of 0.182. When treated with DIM-NPs for 48 h, both MCF7 and MDA-MB-231 cells displayed cytotoxicity at a concentration of 6.25 g/mL compared to untreated cells. Furthermore, in MDA-MB-231 cells, treatment with 2.5 μg/mL of DIM-NPs resulted in a significant decrease in cell migration, propagation, and angiogenesis which was further enhanced at 10 μg/mL. In chicken embryos, treatment with 5 μg/mL of DIM-NPs on day 2 led to a significant reduction in angiogenesis. Furthermore, this treatment induced cell death through a regulatory pathway involving the upregulation of Bax and p53, as well as the downregulation of Bcl-2. These results were supported by in-silico analysis of DIM's binding affinity to key proteins involved in this pathway, namely Bax, Bcl-2, and p53., Conclusion: Our findings show that DIM-NPs induces apoptosis, inhibit migration, and reduce angiogenesis in breast cancer. However, further research using a preclinical cancer model may be necessary to determine the pharmacokinetics of DIM-NPs and ensure their safety and efficacy in vivo., Competing Interests: The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (© 2023 The Authors.)

- Abstract
Background: Curcumin has been used in the treatment of several diseases; however, its low pharmacologic profile reduces its therapeutic use. Towards improving its biological activity, nanoformulations have emerged. Thus, we aimed to determine whether curcumin nanoparticles (Cur-NPs) coated with PEG/chitosan improve the treatment of liver cancer (LC) cells and underpin the molecular mechanisms underlying their anti-cancer activity., Methods: Cur-NPs were synthesised in the form of Cur-PLGA-PEG/chitosan NPs. The effect of Cur-NPs was assessed in HepG2 and Huh 7 LC cells and THLE-2 normal liver cells., Results: The size of synthesised Cur-NPS was determined in the standard range of 141.2 ± 47.5 nm. Compared to THLE-2 cells, LC cells treated with Cur-NPs exerted cytotoxicity at 6.25 µg/mL after 48h. Treatment of HepG-2 cells with 2.5 µg/mL of Cur-NPs inhibited cell migration and this inhibition was augmented at 10 µg/mL ( p < 0.001). Treatment of chicken embryo with 5 µg/mL Cur-NPs reduced angiogenesis ( p < 0.001) of 4-day-old embryos. The nanoformulation upregulated Bax and p53 and downregulated Bcl-2 in a concentration-dependent manner and subsequently induce apoptosis in HepG-2 cells., Conclusion: Treatment of LC cells with Cur-NPs decreased cell proliferation, migration, and angiogenesis, and induced cell death by promoting the proapoptotic pathway.

- Abstract
trans-Anethole a valuable compound derived from star anise widely used by ethnic tribals to manage numerous human diseases. In this study antiproliferative activities of trans-Anethole towards human liver cancer (HepG2), cervical cancer (HeLa) and breast cancer (MCF-7) cells were explored. trans-Anethole showed free radical scavenging potential as assessed by DNA nicking assay. trans-Anethole exhibited strong antiproliferative potential towards HepG2 cells compared to other cell lines. trans-Anethole strongly induced apoptosis in HepG2 cells by significantly upregulating the protein expressions of p53, Caspase-3 and Caspase-9 were assessed by western blotting analysis which highlighted apoptosis-inducing capacity of trans-Anethole against HepG2 cells. Rt-qPCR analysis revealed that trans- Anethole upregulated p53, caspase - 3 and - 9 in comparison to untreated HepG2 cancer cells. Moreover, trans-Anethole provoked the generation of ROS and disruption of MMP. Our research suggests that trans-Anethole may have a significant anticancer therapeutic potential for treating liver cancer., Competing Interests: Declaration of Competing Interest The authors declare that they have no known competing for financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2023 The Authors.

- Abstract
This nonrandomized controlled trial determined the effects of Phoenix dactylifera palm date (Ajwa) intake on the number of infections and hospitalizations associated with fever, neutropenia, and mortality of pediatric cancer patients admitted between 2008 and 2017 to King Abdulaziz University Hospital (Jeddah, Saudi Arabia). Patients were eligible to be enrolled if they fulfilled the inclusion criteria, were not allergic to Ajwa, and were not enrolled in another study. Of 200 screened patients, 56 were included and 144 were excluded. Of the 56, 26 agreed to take Ajwa, and 30 served as controls. Both groups were assessed based on infection rates, frequency of hospital admissions for fever and neutropenia, and mortality rate. Background information regarding demographics, clinicopathological data, and treatment options was documented. Supplementation of Ajwa significantly reduced hospital admissions (for fever-associated neutropenia) and infections ( P = .009 and P < .001, respectively). Off-treatment did not significantly differ between the Ajwa and control groups. The Ajwa group had a better survival rate in comparison to the non-Ajwa group (stratified log-rank P = .005), where the main cause of death of patients in the non-Ajwa group was disease progression associated with infections (77%). In summary, Ajwa intake during the standard treatment of pediatric cancer patients improved their treatment outcome.

- Abstract
Honey exhibits antimicrobial activities against a wide range of bacteria in different milieu. This study aims to compare the effects of five types of honey (both imported and local Saudi honey) against Staphylococcus aureus . The five types of honey (Manuka Honey UMF +20, Manuka Honey UMF +16, Active +10 Manuka Honey, Sidr honey and Nigella sativa honey) were evaluated for their bactericidal/bacteriostatic activities against both methicillin resistant and sensitive S. aureus . The inhibitory effect of honey on bacterial growth was evident at concentrations of 20% and 10% (v/v). Manuka Honey showed the best results. Manuka Honey UMF +20 had a bactericidal effect on both methicillin resistant and sensitive S. aureus . However, Sidr and N. sativa honey exerted only a bacteriostatic effect. The efficacy of different types of honey against S. aureus was dependent on the type of honey and the concentration at which it was administered. Manuka Honey had the best bactericidal activity. Future experiments should be conducted to evaluate the effects of honey on bacterial resistance.

- Abstract
Sickle cell disease (SCD) is an autosomal recessive inherited hemoglobinopathy, characterized by chronic hemolysis and recurrent vaso-occlusive crisis (VOC). This study investigates changes in leucocyte subsets and the relationship between cell adhesion molecule expression and disease manifestations in patients during steady state and acute VOC. We compared soluble E-selectin and P-selectin levels in 84 SCD patients, in steady state and during VOC to 84 healthy controls. Using immunophenotyping, we also compared lymphocyte subsets in these three groups. Further, we compared E-selectin and P-selectin levels in patients of Saudi ethnicity to non-Saudi patients, in all three groups. Lymphocyte subsets showed high percentages of total T lymphocytes, T helper and suppressor lymphocytes, B lymphocytes as well as NK cells in patients with SCD during steady state, while B lymphocytes and NK cells were significantly higher during acute VOC crisis. High levels of both soluble E-selectin (sE-selectin) and soluble P-selectin (sP-selectin) markers were demonstrated in the serum of patients with SCD during both steady state and acute VOC. Levels of selectins were significantly higher in acute VOC. The immunophenotypic expression of L-selectin, on leucocytes, was high in SCD both during steady state and during acute VOC in comparison to normal control subjects. There was no significant difference in all three study groups between Saudi and non-Saudi patients. These findings suggest that patients with SCD have increased expression of adhesion molecules: E-selectin and P-selectin, which play an important role in the pathogenesis of VOC. Despite the distinct phenotype of Saudi patients with SCD, there was no significant difference in levels of soluble E-selectin and soluble P-selectin between Saudi and non-Saudi patients in all three groups. While sickle cell disease is a well-recognized state of chronic inflammation, the role of specific adhesion molecules is steadily unraveling. Studies are underway to investigate the potential role of selectin antagonists, for prevention and reversal of acute vascular occlusions in SCD patients.

- Abstract
Background. Besides lipid-lowering effect of statins, they have been shown to have nonlipid lowering effects, such as improving bone health. An improvement in bone mineral density (BMD) has been indicated in some studies after the use of statins, in addition to an increase in 25-hydroxyvitamin D (25OHD) level. The aim of this study is to explore the association between statins and bone health taking into consideration 25OHD level and BMD. Methods. This is a randomized, cross-sectional comparative study. Subjects were divided into two groups, hypercholesterolemic participants taking simvastatin or atorvastatin as the study group and a matched control group not taking statins. All participants were assessed for serum 25OHD and BMD at lumbar spine and femoral neck. Results. A total of 114 participants were included in the study, 57 participants in each group. Results of serum 25OHD showed no significant difference between study and control groups (P = 0.47), while BMD results of lumbar spine and femoral neck showed significant difference (P = 0.05 and 0.03, resp.). Conclusion. Simvastatin and atorvastatin, at any dose for duration of more than one year, have no additive effect on 25OHD level but have a positive effect on the BMD.

- Abstract
Osteoporosis is a complicated and preventable disease with major morbidity complications that affects millions of people. In the last 15 years, there have been numerous studies and research in the new fields of pharmacogenetics and pharmacogenomics related to osteoporosis. Numerous "candidate genes" have been identified and have been found to be associated with osteoporosis as well as the treatment of osteoporosis. Many studies have found conflicting results on different polymorphisms and whether or not they are related to bone mineral density and osteoporosis. There is a need for larger and better designed pharmacogenomic studies related to osteoporosis incorporating a greater variety of candidate genes. The evaluation of osteoporosis and fracture risk is moving from a risk stratification approach to a more individualized approach, in which an individual's absolute risk of fracture is evaluable as a constellation of the individual's environmental exposure and genetic makeup. Therefore, the identification of gene variants associated with osteoporosis phenotypes or response to therapy might help individualize the prognosis, treatment, and prevention of fracture. This review focuses on major candidate genes and what needs to be done to take the genetics of osteoporosis and incorporate them into the pharmacogenomics of the management of osteoporosis.
