Alternate Day Oral Iron Replacement Versus Daily Intake In Women With Iron-Deficiency Anemia In Basrah, Muntadar Jafar Mawla, Mohammed A. Al-Anssari, Qutaiba M. Dawood, Murtadha A. Jeber, Asaad A. Khalaf

Iraqi National Journal of Medicine

Background: Iron-deficiency anemia (IDA) remains a major global health concern, disproportionately affecting women of reproductive age. Conventional daily iron supplementation, though effective, is often associated with poor adherence due to gastrointestinal side effects. Emerging evidence suggests that alternate-day dosing may enhance iron absorption and tolerability, but comparative efficacy data in clinical settings remain limited. Aim: This study aimed to compare the hematological and iron store responses of women with IDA in Basrah, Iraq, between alternate-day and daily oral iron supplementation regimens. Methods: A total of 97 women with confirmed IDA (hemoglobin [Hb] < 12 g/dL, serum ferritin < 15 ng/mL) were enrolled in a prospective follow-up cohort study. The participants were divided into two groups: Group B (n = 48) received 100 mg of elemental iron daily, while Group A (n = 49) received the same dose every other day. Serum ferritin and hematological parameters (Hb, red blood cell [RBC] count, hematocrit) were assessed at baseline, three weeks, six weeks, and three months. ANOVA and paired t-tests were used for statistical analysis, with a significance level of P < 0.05. Results: Compared to the daily group, the alternate-day group exhibited a significantly higher mean increase in serum ferritin (28.6 ± 4.2 ng/mL vs. 22.3 ± 3.8 ng/mL, P = 0.001) and hemoglobin (2.8 ± 0.5 g/dL vs. 2.1 ± 0.4 g/dL, P = 0.001) at three months. The alternate-day group demonstrated earlier and more sustained improvements in iron reserves (P < 0.01 at all follow-ups), but both regimens increased RBC counts. Conclusion: In women with IDA, alternate-day iron supplementation is more effective in restoring hemoglobin and iron stores than daily dosing, possibly due to improved absorption and reduced hepcidin inhibition. These findings suggest potential benefits for patient adherence and clinical outcomes, supporting the use of alternate-day regimens as a superior therapeutic approach. To validate these results, further randomized controlled trials are necessary.

Idiopathic scoliosis (IS) is the most common form of spinal deformity with unclear pathogenesis. In this study, we first reanalyzed the loci associated with IS, drawing upon previous studies. Subsequently, we mapped these loci to candidate genes using either location-based or function-based strategies. To further substantiate our findings, we verified the enrichment of variants within these candidate genes across several large IS cohorts encompassing Chinese, East Asian, and European populations. Consequently, we identified variants in the EPHA4 gene as compelling candidates for IS. To confirm their pathogenicity, we generated zebrafish mutants of epha4a. Remarkably, the zebrafish epha4a mutants exhibited …

Cancer Vaccination And Immune-Based Approaches In Pancreatic Cancer, Matthew D. Bloom, Ali Raza Shaikh, Zhengyang Sun, Babar Bashir, Adam E. Snook

Department of Medical Oncology Faculty Papers

Pancreatic ductal adenocarcinoma (PDAC) is an aggressive malignancy with high recurrence rates even after curative resection and adjuvant chemotherapy. Although immunotherapeutic approaches, such as immune checkpoint blockade (ICB), have revolutionized the treatment of some solid tumor malignancies, this has not been the case for PDAC. Several characteristics of PDAC, including its distinctive desmoplastic tumor microenvironment (TME), intratumor heterogeneity, and poor antigenicity and immune cell infiltration, contribute to its dismal immunotherapeutic landscape. Cancer vaccines offer one approach to overcoming these barriers, particularly in the resectable or borderline resectable settings, where tumor burden is low and immunosuppression is less pronounced. Various vaccination …

Poly(ADP-ribose) polymerase (PARP) inhibitors (PARPis) are used to treat BRCA-mutated (BRCAm) cancer patients; however, resistance has been observed. Therefore, biomarkers to indicate PARPi resistance and combination therapy to overcome that are urgently needed. We identified a high prevalence of activated FGF receptor 3 (FGFR3) in BRCAm triple-negative breast cancer (TNBC) cells with intrinsic and acquired PARPi resistance. FGFR3 phosphorylated PARP1 at tyrosine 158 (Y158) to recruit BRG1 and prolong chromatin-loaded MRE11, thus promoting homologous recombination (HR) to enhance PARPi resistance. FGFR inhibition prolonged PARP trapping and synergized with PARPi in vitro and in vivo. High-level PARP1 Y158 phosphorylation (p-Y158) positively …
