ABSTRACT

The rise in cancer rates in Sub-Saharan Africa (SSA), combined with limited access to Western pharmaceuticals, has sparked growing adoption of traditional and complementary medicine (T&CM) for cancer treatment in the region. However, many challenges exist, including the lack of reliable evidence-based research on these products, scarcity of standardized documentation as part of cancer registries, limited physician expertise, and negative effects on mortality. Nonetheless, herbal medicines also present opportunities for further research, development, and stakeholder education, potentially benefiting the regional healthcare systems in SSA countries and global health as whole. Recent trends highlight the willingness of patients to use mobile-based applications that provide accurate information on herbal therapeutics, reflecting the increasing adoption of internet and smart/mobile phone services in SSA. To maximize the potential benefits of traditional and complementary medicine, it is necessary to bridge the trust gap between the public, local practitioners, and Western healthcare providers. Sustained funding and policy support are needed to complement these initiatives. Our preliminary survey hopes to inspire the community and policymakers to embrace innovative solutions, fostering a forward-looking approach to cancer care in SSA.

ABSTRACT

BACKGROUND/AIM: Due to still unresolved questions regarding viruses as either a primary cause or a comorbidity in cancer, we examined a potential immune response to cytomegalovirus (CMV) in the renal cell carcinoma (RCC) setting using genomics and bioinformatics approaches. MATERIALS AND METHODS: Specifically, we assessed chemical complementarity scores (CSs) for solid tissue normal resident, T-cell receptor (TCR) complementarity determining region 3 (CDR3s) and CMV antigens and determined whether higher or lower CS groups were associated with a higher or lower survival probability. RESULTS: This was indeed the case, with all such analyses consistently indicating a lower overall and progression-free survival for the cases representing the higher TCR CDR3-CMV antigen chemical CSs. This basic result was obtained for two separate RCC datasets and multiple CMV antigens. CONCLUSION: The results raise the question, to what extent a systemic CMV infection may represent an important co-morbidity for RCC.

ABSTRACT

Malignant melanoma is the most aggressive form of skin cancer. Standard treatment options include surgery, radiation therapy, systemic chemotherapy, targeted therapy, and immunotherapy. Combining these modalities often yields better responses. Surgery is suitable for localized cases, sometimes involving lymph node dissection and biopsy, to assess the spread of the disease. Radiation therapy may be sometimes used as a standalone treatment or following surgical excision. Systemic chemotherapy, while having low response rates, is utilized as part of combination treatments or when other methods fail. The development of resistance to systemic chemotherapies and associated side effects have prompted further research and clinical trials for novel approaches. In the case of advanced-stage melanoma, a comprehensive approach may be necessary, incorporating targeted therapies and immunotherapies that demonstrate significant antitumor activity. Targeted therapies, including inhibitors targeting BRAF, MEK, c-KIT, and NRAS, are designed to block the specific molecules responsible for tumor growth. These therapies show promise, particularly in patients with corresponding mutations. Combination therapy, including BRAF and MEK inhibitors, has been evidenced to improve progression-free survival; however, concerns about resistance and cutaneous toxicities highlight the need for close monitoring. Immunotherapies, leveraging tumor-infiltrating lymphocytes and CAR T cells, enhance immune responses. Lifileucel, an FDA-approved tumor-infiltrating lymphocyte therapy, has demonstrated improved response rates in advanced-stage melanoma. Ongoing trials continue to explore the efficacy of CAR T-cell therapy for advanced melanoma. Checkpoint inhibitors targeting CTLA-4 and PD-1 have enhanced outcomes. Emerging IL-2 therapies boost dendritic cells, enhancing anticancer immunity. Oncolytic virus therapy, approved for advanced melanoma, augments treatment efficacy in combination approaches. While immunotherapy has significantly advanced melanoma treatment, its success varies, prompting research into new drugs and factors influencing outcomes. This review provides insights into current melanoma treatments and recent therapeutic advances.

ABSTRACT

Copy number variation (CNV) of certain genes in pediatric Acute Lymphoblastic Leukemia (ALL) impacts gene expression levels. Here, we aimed to investigate the potential prognostic utility of CNVs in pediatric B-ALL and T-ALL. Using genomics files representing cases from the TARGET-ALL-P2 dataset, genes commonly involved in ALL development were analyzed for CNVs. Case IDs representing increased copy numbers for SOX11, PDGFRB, and MDK represented a worse overall survival probability specifically for B-ALL (logrank p=0.021, p=0.0052, p=0.019, respectively). These data support the continued investigation of using CNVs for clinical prognostic biomarkers for pediatric B-ALL.

ABSTRACT

Hypoxia has established associations with aggressive tumor phenotypes in many cancers. However, it is not currently understood whether tumor hypoxia levels map to distinct immune infiltrates in cutaneous melanoma, potentially unveiling novel therapeutic targets. To this end, we leveraged a previously identified seven-gene hypoxia signature to grade hypoxia levels of 460 cutaneous melanomas obtained from the Broad Institute GDAC Firehose portal. CIBERSORTx ( https://cibersortx.stanford.edu/ ) was employed to calculate the relative abundance of 22 mature human hematopoietic populations. Clinical outcomes and immune cell associations were assessed by computational means. Results indicated that patients with high-hypoxia tumors reported significantly worse overall survival and correlated with greater Breslow depth, validating the in-silico methodology. High-hypoxia tumors demonstrated increased infiltration of activated and resting dendritic cells, resting mast cells, neutrophils, and resting NK cells, but lower infiltration of gamma-delta T cells. These data suggest that high tumor hypoxia correlates with lower survival probability and distinct population differences of several tumor-infiltrating leukocytes in cutaneous melanomas.

ABSTRACT

BACKGROUND: Preoperative anemia is common in patients undergoing total hip arthroplasty (THA) and total knee arthroplasty (TKA). Several definitions of anemia have been described, with no clear consensus on the optimal one for preoperative screening. We hypothesized that depending on the definition used preoperatively, the proportion of anemic patients identified who would require a postoperative allogeneic blood transfusion would vary significantly. METHODS: A total of 681,141 patients were identified in a national database who underwent either THA or TKA. Preoperative anemia was classified according to the World Health Organization (WHO) definition, Cleveland Clinic (CC) definition, or race, age, and sex-specific definition described by Beutler et al in 2006. The optimal preoperative (OP) hemoglobin thresholds to predict perioperative transfusions were also calculated using receiver operating characteristic curves. RESULTS: When using the WHO definition, 18% of anemic patients required a transfusion versus 14% (OP definition), 12% (CC definition), and 16% (Beutler definition). Similarly, 0.69% of anemic patients sustained a periprosthetic joint infection within 30 days using the WHO definition versus 0.59% (OP definition), 0.60% (CC definition), or 0.66% (Beutler definition). Using the WHO definition, 5.3% of patients would have sustained a major complication versus 4.5% (OP definition), 4.4% (CC definition), and 5.0% (Beutler definition). CONCLUSIONS: Variation in the definition of anemia for preoperative screening in THA and TKA results in substantial differences in discriminative ability to predict perioperative transfusions. The WHO definition identified the largest proportion of patients who ultimately received a perioperative transfusion.

ABSTRACT

BACKGROUND: Social media platforms are often used for research dissemination and collaboration. Given the increased prevalence of online-only publications, understanding what drives research dissemination is important. Here, we analyzed factors associated with increased social media attention among peer-reviewed publications in total knee arthroplasty, total hip arthroplasty, and unicompartmental knee arthroplasty. METHODS: We analyzed publications about total knee arthroplasty, total hip arthroplasty, or unicompartmental knee arthroplasty from 2010 to 2022 using a national database. We analyzed a weighted count of social media mentions, using negative binomial regressions adjusting for days since publication. Publications on "hot topics" in arthroplasty were examined including navigation/robotics, COVID-19, race/ethnicity, body mass index, and reimbursement. There were 9,542 publications included, 4,216 (44%) were open access (OA), 338 (3.5%) included navigation, 32 (0.34%) discussed race/ethnicity, 20 (0.2%) discussed COVID-19, 3,840 (40%) were randomized studies, 30 (0.3%) discussed reimbursement, and 2,867 (30%) were in top-10 orthopaedic journals. RESULTS: Factors associated with higher weighted score included studies about COVID-19 (50 versus 6.0, P < .001), race/ethnicity (15.8 versus 6.0, P < .001), OA status (6.3 versus 5.8, P = .001), and randomized studies (6.5 versus 5.7, P < .001). Studies from top-10 journals had a lower score (5.8 versus 6.2, P = .025), as did studies about body mass index (3.4 versus 6.1, P = .001). Studies about navigation and reimbursement did not have significantly different scores. CONCLUSIONS: Studies on COVID-19, race/ethnicity, randomized studies, and OA publication were associated with increased social media while those in top-10 orthopaedic journals had lower scores. LEVEL OF EVIDENCE: Level IV, Prognostic Study.
