Neurocognitive outcomes in pediatric hematological cancer survivors post-HSCT: A systematic review.

BACKGROUND: Pediatric hematological cancer survivors who undergo hematopoietic stem cell transplantation (HSCT) may experience long-term neurocognitive impairments. This systematic review aims to assess the neurocognitive outcomes in pediatric hematological cancer survivors at least 5 years post-HSCT. METHODOLOGY: A comprehensive search was conducted in multiple databases, including PubMed, ScienceDirect, Cochrane Library, and ClinicalTrials.gov, until October 2022. Relevant studies assessing the neurocognitive affect after 5 years of HSCT were identified and included in the review. The quality of included studies was assessed using the ROBINS-I tool to evaluate the risk of bias. RESULTS: A total of five studies met the inclusion criteria and were included in the review. The studies consistently demonstrated adverse effects of HSCT on neurocognitive outcomes in pediatric hematological cancer survivors after 5 years of the treatment. The most prominent impact was observed on global cognitive outcomes, including intelligence, attention, memory, and executive functioning. Specific cognitive domains, such as processing speed and academic achievement, were also significantly affected. Several studies reported a relationship between HSCT-related factors (e.g., age at transplantation, radiation therapy, graft-versus-host disease) and neurocognitive impairments. CONCLUSION: This systematic review provides evidence of the adverse impact of HSCT on neurocognitive outcomes in pediatric hematological cancer survivors at least 5 years post-transplantation. The findings highlight the importance of long-term monitoring and intervention strategies to mitigate these neurocognitive sequelae. Future research should focus on identifying risk factors and developing targeted interventions to optimize the neurocognitive functioning of this vulnerable population. Healthcare professionals involved in the care of pediatric hematological cancer survivors should be aware of these potential long-term neurocognitive effects and incorporate appropriate assessments and interventions into survivorship care plans.

Network pharmacology and molecular docking analysis on potential molecular targets and mechanism of action of BRAF inhibitors for application in wound healing.

Topical application of BRAF inhibitors has been shown to accelerate wound healing in murine models, which can be extrapolated into clinical applications. The aim of the study was to identify suitable pharmacological targets of BRAF inhibitors and elucidate their mechanisms of action for therapeutic applicability in wound healing, by employing bioinformatics tools including network pharmacology and molecular docking. The potential targets for BRAF inhibitors were obtained from SwissTargetPrediction, DrugBank, CTD, Therapeutic Target Database, and Binding Database. Targets of wound healing were obtained using online databases DisGeNET and OMIM (Online Mendelian Inheritance in Man). Common targets were found by using the online GeneVenn tool. Common targets were then imported to STRING to construct interaction networks. Topological parameters were assessed using Cytoscape and core targets were identified. FunRich was employed to uncover the signaling pathways, cellular components, molecular functions, and biological processes in which the core targets participate. Finally, molecular docking was performed using MOE software. Key targets for the therapeutic application of BRAF inhibitors for wound healing are peroxisome proliferator-activated receptor γ, matrix metalloproteinase 9, AKT serine/threonine kinase 1, mammalian target of rapamycin, and Ki-ras2 Kirsten rat sarcoma viral oncogene homolog. The most potent BRAF inhibitors that can be exploited for their paradoxical activity for wound healing applications are Encorafenib and Dabrafenib. By using network pharmacology and molecular docking, it can be predicted that the paradoxical activity of BRAF inhibitors can be used for their potential application in wound healing.

Metformin alone and in combination with sitagliptin induces depression and impairs quality of life in type 2 diabetes mellitus patients: An observational study.

BACKGROUND: Various studies have reported the association of cognition and depression with diabetes. Literature suggests that metformin and sitagliptin used to control hyperglycemia in type 2 diabetes mellitus (T2DM) possess a beneficial effect on neurological symptoms associated with diabetes. However, there are scarce data in the clinical setting. Thus, this study aims to compare depression, cognitive impairment, and quality of life (QoL) of newly diagnosed T2DM patients with those of healthy individuals. Further, the impact of metformin alone or in combination with dipeptidyl peptidase-4 inhibitors on cognition, depression, and QoL of T2DM patients was also compared with newly diagnosed T2DM patients. MATERIALS AND METHODS: This was a prospective observational study in 120 subjects. The subjects were equally divided into four groups: healthy controls, newly diagnosed T2DM patients, and T2DM patients taking either metformin alone or in combination with sitagliptin. We assessed cognition using Mini-Mental State Examinations (MMSE), depression using Hamilton Depression Rating Scale (HAM-D), and health status using Short-Form Health Survey-36 (SF-36). RESULTS: No significant change in MMSE score was observed among the groups. However, a significant increase in the HAM-D score of newly diagnosed patients (p < 0.001), T2DM patients receiving metformin alone (p < 0.05), and in combination with sitagliptin (p < 0.001) was observed as compared to healthy controls (p < 0.001). Also, a statistically significant increase in HAM-D score was observed in patients receiving sitagliptin in combination with metformin as compared to metformin alone (p < 0.01). A decrease in SF-36 scores was observed in all groups as compared to healthy controls. CONCLUSION: To conclude, this preliminary study indicates that T2DM patients are most likely to suffer from depression and impaired QoL. Moreover, both the conventional and recent antidiabetic agents might lead to neurobehavioral complications and adverse impact on the QoL of these patients. Thus, we warrant the assessment of cognitive functions, depression, and QoL in patients receiving metformin and sitagliptin.

Subfoveal Choroidal Thickness and Associated Changes of Angiogenic Factors in Women with Severe Preeclampsia.

OBJECTIVE: Severe preeclampsia complicates roughly 1% of all pregnancies. One defining feature of severe preeclampsia is new onset visual disturbance. The accessibility of the choroid to high-resolution, noninvasive imaging makes it a reasonable target of investigation for disease prediction, stratification, or monitoring in preeclampsia. This study aimed to compare subfoveal choroidal thickness between women with severe preeclampsia and those with normotensive pregnancies, and to investigate associations between such findings and other indicators of disease severity, including gestational age and serum angiogenic factors. STUDY DESIGN: We designed a case-control study comprised of 36 women diagnosed with severe preeclampsia (cases) matched to 37 normotensive women (controls) by race/ethnicity and parity, all diagnosed in the postpartum period. All patients underwent enhanced depth imaging spectral-domain optical coherence tomography and serum analysis. RESULTS: Cases showed no difference in subfoveal choroidal thickness compared with controls (p = 0.65). Amongst cases, subfoveal choroidal thickness and gestational age at delivery were inversely related (r = 0.86, p < .001). There was a positive association of placental growth factor with subfoveal choroidal thickness amongst cases (r = 0.54, p = 0.002). CONCLUSION: This study suggests a relationship between the degree of disease severity and the magnitude of choroidal thickening. We also show an association between this index and placental growth factor level in the postpartum period.

Reagent-Controlled Divergent Synthesis of 2-Amino-1,3-Benzoxazines and 2-Amino-1,3-Benzothiazines.

A reagent-controlled chemoselective process has been devised for the synthesis of 4H-1,3-benzoxazines and related biologically important heterocycles in high yields under mild conditions. These scaffolds could be efficiently constructed using two different chemoselective reactions that rely on the choice of reagents and reaction conditions. The treatment of various 2-amino-arylalkyl alcohols with isothiocyanates afforded thiourea intermediates, which were reacted in situ with molecular iodine in the presence of triethylamine to give 2-amino-4H-1,3-benzoxazines, whereas the corresponding 2-amino-4H-1,3-benzothiazines were obtained by the reaction of thiourea intermediates in the presence of T3P (a mild cyclodehydrating agent) and triethylamine as the base. The described protocol represents the first example for the synthesis of 4H-1,3-benzoxazines via the dehydrosulfurization method using molecular iodine as the reagent.

Artificial intelligence in glaucoma.

PURPOSE OF REVIEW: The use of computers has become increasingly relevant to medical decision-making, and artificial intelligence methods have recently demonstrated significant advances in medicine. We therefore provide an overview of current artificial intelligence methods and their applications, to help the practicing ophthalmologist understand their potential impact on glaucoma care. RECENT FINDINGS: Techniques used in artificial intelligence can successfully analyze and categorize data from visual fields, optic nerve structure [e.g., optical coherence tomography (OCT) and fundus photography], ocular biomechanical properties, and a combination thereof to identify disease severity, determine disease progression, and/or recommend referral for specialized care. Algorithms have become increasingly complex in recent years, utilizing both supervised and unsupervised methods of artificial intelligence. Impressive performance of these algorithms on previously unseen data has been reported, often outperforming standard global indices and expert observers. However, there remains no clearly defined gold standard for determining the presence and severity of glaucoma, which undermines the training of these algorithms. To improve upon existing methodologies, future work must employ more robust definitions of disease, optimize data inputs for artificial intelligence analysis, and improve methods of extracting knowledge from learned results. SUMMARY: Artificial intelligence has the potential to revolutionize the screening, diagnosis, and classification of glaucoma, both through the automated processing of large data sets, and by earlier detection of new disease patterns. In addition, artificial intelligence holds promise for fundamentally changing research aimed at understanding the development, progression, and treatment of glaucoma, by identifying novel risk factors and by evaluating the importance of existing ones.

PROPHYLACTIC PREOPERATIVE LASER RETINOPEXY DOES NOT REDUCE THE OCCURRENCE OF RHEGMATOGENOUS RETINAL COMPLICATIONS IN MACULAR SURGERY.

PURPOSE: Knowledge on the utility of prophylactic 360° laser retinopexy before pars plana vitrectomy in the absence of peripheral retinal pathology is limited. This study compares the occurrence of rhegmatogenous events in the setting of small-gauge pars plana vitrectomy with and without prophylactic preoperative laser. METHODS: Our multicenter, retrospective case-control analysis reviewed patients who underwent epiretinal membrane removal or macular hole repair through 23- or 25-gauge pars plana vitrectomy: 205 controls who did not receive prophylactic laser and 176 cases who received preoperative prophylactic laser retinopexy anterior to the equator. Main outcome measures were the rate and characteristics of postoperative retinal tears and detachments. Patients with previous pars plana vitrectomy or significant retinal disease were excluded. RESULTS: Of those patients with prophylactic laser and those without, there was no significant difference in the number of retinal breaks (1.7% vs. 0.49%, respectively; P = 0.339) or retinal detachments (0% vs. 0.49%, respectively; P = 1.00). Of the lasered group, there was one sclerotomy-related retinal break and two non-sclerotomy-related retinal breaks. Of the nonlasered group, there was one non-sclerotomy-related retinal break and one sclerotomy-related retinal detachment. CONCLUSION: Preoperative prophylactic peripheral laser retinopexy does not seem to offer an added benefit in the prevention of intraoperative and postoperative rhegmatogenous events.

Coincidental Optic Nerve Meningioma and Thyroid Eye Disease.

A 57-year-old woman with diabetes mellitus, hypertension, obesity, and Graves disease presented with clinical evidence of thyroid eye disease (TED) and optic neuropathy. She was referred when a tapered dose of steroids prompted worsening of her TED. CT and MRI were consistent with TED and bilateral optic nerve meningioma. To the authors' knowledge, this is the first reported case of concurrent TED and unsuspected bilateral optic nerve meningioma. When investigating the etiology of TED-associated optic neuropathy, careful attention to orbital imaging is required because coexisting pathology may exist.

Bilateral Orbital Abscesses After Strabismus Surgery.

Infectious orbital complications after strabismus surgery are rare. Their incidence is estimated to be 1 case per 1,100 surgeries and include preseptal cellulitis, orbital cellulitis, subconjunctival and sub-Tenon's abscesses, myositis, and endophthalmitis. This report describes the case of an otherwise healthy 3-year-old boy who underwent bilateral medial rectus recession and disinsertion of the inferior obliques. A few days after surgery, the patient presented with bilateral periorbital edema and inferotemporal chemosis. A series of CT scans with contrast revealed inferotemporal orbital collections OU. The patient immediately underwent transconjunctival drainage of fibrinous and seropurulent collections in the sub-Tenon's space and experienced rapid improvement a few days later. The patient is reported to be in stable condition in a follow-up examination performed more than a year after the reported events.

A Systematic Review of the Impact of Benzimidazole-based Anthelmintics on Lung Cancer in Animal Models.

BACKGROUND: Emerging studies have reported the potential anticancer activity of FDA-approved benzimidazole-based anthelmintics against lung cancer. Therefore, the current systematic review aimed to explore the anticancer activity of benzimidazole-based anthelmintics in lung cancer animal models. METHOD: The databases including Pubmed, ScienceDirect, and Google Scholar were searched till April 2024 for the animal studies evaluating the anticancer activity of benzimidazole-based anthelmintics against lung cancer. The relevant data was extracted in the prepared format in Microsoft Excel. Systematic Review Center for Laboratory Animal Experimentation (SYRCLE) risk of bias (RoB) was used to assess the quality of included studies. The protocol for this study has been registered in PROSPERO (Registration number: CRD42022352141). RESULTS: Initially, we obtained 4150 articles, and finally eight articles were included in the current study. The information in the included studies was a bit diversified including different benzimidazole-based anthelmintics, dosage, route of administration, and duration of experiments. However, all studies reported that exposure to benzimidazole-based anthelmintics decreased tumor size and tumor volume in animal models of lung cancer. CONCLUSION: In conclusion, benzimidazole-based anthelmintics have the potential to treat lung cancer. However, more controlled and thorough preclinical studies are required to evaluate its efficacy, safety, and mechanism of anticancer activities.

Nanomedicine for the eradication of Helicobacter pylori: recent advances, challenges and future perspective.

Helicobacter pylori infection is linked to gastritis, ulcers and gastric cancer. Nanomedicine offers a promising solution by utilizing nanoparticles for precise drug delivery, countering antibiotic resistance and delivery issues. Nanocarriers such as liposomes and nanoparticles enhance drug stability and circulation, targeting infection sites through gastric mucosa characteristics. Challenges include biocompatibility, stability, scalability and personalized therapies. Despite obstacles, nanomedicine's potential for reshaping H. pylori eradication is significant and showcased in this review focusing on benefits, limitations and future prospects of nanomedicine-based strategies.

Helicobacter pylori is associated with stomach problems like gastritis, ulcers and cancer. The use of tiny particles, called nanomedicine, may help to precisely deliver drugs to treat these bacterial infections. Using nanomedicine can help to combat drug resistance and drug-delivery issues by making drugs more stable and specifically targeting the infection site. However, there are challenges such as making sure it is safe, stable and can be scaled up for many people. This review discusses the potential of nanomedicine to fight H. pylori infection, its advantages and disadvantages, and how it could be used in the future.

The anti-seizure potential of cysteine leukotriene receptor antagonists: A systematic review of animal studies.

BACKGROUND: Emerging literature has suggested the antiepileptic activity of cysteine leukotriene receptor (CysLTR) antagonists in experimental animals of epilepsy. Leukotrienes are substances that cause inflammation and affect brain activity, blood flow, oxidation, and inflammation in the brain. These processes are related to epilepsy and its complications. CysLTR antagonists are drugs that prevent leukotrienes from working. They may be useful for treating epilepsy, especially for people who do not respond to other drugs. Therefore, the current study aims to systematically review the potential anti-seizure effect of CysLTR antagonists in experimental studies. METHOD: We systematically reviewed the online databases using online databases such as Google Scholar, science direct, and PubMed until December 2022 to identify experimental studies assessing the anti-seizure activity of CysLTR antagonists. The Systematic Review Centre for Laboratory Animal Experimentation (SYRCLE) was used to evaluate the risk of bias (RoB) of the included studies. RESULTS: Initially we identified 3823 studies. After screening using inclusion and exclusion criteria, 8 studies were finally included in the current study. All included studies, reported that CysLTR antagonists reduced the intensity of seizures in animal models of epilepsy. CONCLUSION: In conclusion, CysLTR antagonists could be a potential therapeutic approach for the treatment of epilepsy. However, further preclinical and clinical studies are required to confirm their efficacy, safety, and mechanism of anti-seizure activity.

Short-Term Impact of Hematopoietic Stem Cell Transplantation on Depressive Behavior, Cognition and Quality of Life in Leukemia Patients.

Hematopoietic stem cell transplantation (HSCT) or Bone Marrow Transplantation (BMT) has significantly improved the survival rates of patients suffering from hematological malignancies. However, the cure can only be achieved at the price of morbidity and long-term complications. Thus, this study aimed to evaluate the short-term effect of HSCT on depressive behavior, cognition, and quality of life (QoL) in leukemia patients. Sixty patients were included in this prospective observational study. The current study assessed depression using Patient Health Questionnaire (PHQ-9) scale, cognition using Montreal Cognitive Assessment (MOCA) scale and QoL using European Organization for the Research and Treatment of Cancer Quality of Life Questionnaire (EORTC QLQ C30) before 7 days of the therapy i.e., preconditioning/baseline (TP1) and after 30 days of the treatment (TP2) in leukemia patients undergoing HSCT. At TP2, there was a significant improvement in PHQ-9 (p = 0.001), MOCA (p < 0.0001), functional scale (p < 0.0001) and global health & QoL scale (p = 0.001) of EORTC QLQ C30 scores whereas there was a significant decrease in symptom scale of EORTC QLQ C30 score (p = 0.005). Furthermore, at TP2 a statistically significant (p < 0.05) negative correlation was observed between MOCA and symptom scale of EORTC QLQ C30 after Pearson correlation analysis. In conclusion, post-30 days of HSCT there was alleviation in depressive behavior, cognition, and QoL in leukemia patients compared to before therapy.

The prevalence of multidrug resistance in uropathogens of patients admitted in the intensive care unit of a tertiary care hospital.

Urinary tract infections (UTIs) are among the most common bacterial infections, posing significant public health challenges due to increasing antimicrobial resistance (AMR). This study aims to assess the prevalence, demographic characteristics, microbial profile, and antimicrobial resistance patterns in Indian patients with UTIs admitted to intensive care unit. A total of 154 patients with positive UTIs were included in this cross-sectional study. The prevalence data including demographics, microbial isolates, and antimicrobial susceptibility patterns were collected. Additionally, risk factors for multidrug resistance uropathogens were assessed using multivariate analyses. The patient cohort had diverse demographic, with a slight male predominance of 52.6% (n = 81). The most common comorbidities were hypertension 59.1% (n = 91) and diabetes mellitus 54.5% (n = 84). The microbial profile was dominated by gram-negative bacteria, particularly Escherichia coli 26.62% (n = 41) and Klebsiella pneumoniae 17.53% (n = 27). The predominant gram-positive and fungal isolate was Enterococcus faecium 7.14% (n = 11) and Candida spp. 18.83% (n = 29), respectively. Substantial resistance was noted against common antimicrobials, with variations across different pathogens. Gram-negative bacteria, particularly Escherichia coli and Klebsiella pneumoniae, exhibited high MDR rates, emphasizing the challenge of antimicrobial resistance. Multivariate logistic regression identified age groups 50-65 and over 65, and prolonged catheterization as significant risk factors for MDR infections. A significantly high resistance rate among pathogens emphasizes the need for judicious antimicrobial use. Our findings emphasize the necessity of ongoing surveillance and tailored interventions based on local pathogen prevalence and antibiogram data to effectively address the threat of AMR threat for better management of UTI management in ICU settings.

Unilateral retinopathy secondary to occult primary intraocular lymphoma.

PURPOSE: The purpose of the study is to report the clinical case of a 53-year-old woman whose presenting manifestation of primary intraocular lymphoma (PIOL) was unilateral retinal degeneration. METHOD: A case report was created with review of clinical, imaging, electrophysiologic, and pathological investigations. RESULTS: A 53-year-old woman with a distant history of ocular herpes simplex developed progressive central visual loss and intermittent photopsia over 4 years in her right eye. Ophthalmic examination revealed reduced visual acuity OD, central scotoma, and minimal ocular findings. Autofluorescence and infrared imaging revealed mild reflectance changes in the temporal macula, and spectral-domain optical coherence tomography identified mild disruptions of inner segment/outer segment junctions in the subfoveal region of the right eye. A mild window defect was seen on fluorescein angiography. Electrophysiology with multifocal electroretinogram (ERG) revealed evidence of unilateral macular dysfunction. Full-field ERGs revealed progressive global retinal dysfunction over 6 months, with unilateral decreases in amplitude and implicit time shifts, as seen in cases of autoimmune retinopathies. The eye eventually exhibited mild vitreous cellular infiltration on ophthalmoscopic examination, and vitrectomy diagnosed B cell non-Hodgkin's lymphoma. Further evaluation revealed no evidence of central nervous system or systemic disease, consistent with occult PIOL. CONCLUSIONS: This case illustrates an atypical presentation of PIOL characterized by unilateral retinal disease presenting with symptoms and signs of macular dysfunction. Clinical and ERG features evolved into an acute zonal occult outer retinopathy (AZOOR)-like phenotype. PIOL should be considered in atypical cases of AZOOR with vitreal reactions, and some cases of AZOOR may be related to B cell lymphocyte disorders.

Diabetes and deaths of COVID-19 patients: Systematic review of meta-analyses.

Background: COVID-19 is affecting all kinds of patients including diabetics. This article provides an overview of conducted meta-analyses regarding the effect of diabetes on the deaths of COVID-19 patients. Methodology: The study was conducted as per preferred reporting items for systematic reviews and meta-analysis (PRISMA) statement. Data sources: The relevant meta-analyses were searched on PubMed till April 2021 and data was extracted from 24 relevant meta-analyses. The overall estimate was calculated in terms of odds ratio or relative risk with a 95% confidence interval. Results: A total of 09 meta-analyses showed the association of diabetes with the death of COVID-19 patients and 15 meta-analyses have reported the association of diabetes with other comorbidities in the death of COVID-19 patients. The pooled odds ratio or relative risk has shown a significant association of diabetes alone or its associated comorbidities with deaths of COVID-19 patients. Conclusion: Patients with diabetes and its associated comorbidities need more monitoring if get SARS-Cov-2 infection to reduce deaths.

Network pharmacology and molecular docking study-based approach to explore mechanism of benzimidazole-based anthelmintics for the treatment of lung cancer.

Emerging studies have reported the potential anticancer activity of benzimidazole-based anthelmintics (BBA) against lung cancer (LC). However, mechanism underlying the anticancer activity of BBA is unclear. Therefore, in the current study, network pharmacology and molecular docking-based approach were used to explore the potential molecular mechanism for the treatment of LC. The potential targets for BBA were obtained from multiple databases including SwissTargetPrediction, Drug Bank, Therapeutic Target Database, and Comparative Toxicogenomics Database while LC targets were collected from DisGeNet gene discovery platform, Integrated Genomic Database of NSCLC, Catalogue of Somatic Mutations in Cancer and Online Mendelian Inheritance in Man database. Protein-protein interaction (PPI) diagram of common targets was constructed using STRING online platform. Topological analysis was performed using Cytoscape and gene enrichment analysis was conducted using FunRich software. Highest degree targets were then confirmed using molecular docking and molecular dynamics simulations. The BBA were prioritized according to their S scores, with ricobendazole ranking highest followed by flubendazole, fenbendazole, mebendazole, triclabendazole, albendazole, oxibendazole, parbendazole, thiabendazole and oxfendazole. The potential targets of BBA identified using topological analysis and molecular docking were found to be CCND1 (cyclin D1), EGFR (Epidermal Growth Factor Receptor), ERBB2 (Erb-B2 Receptor Tyrosine Kinase 2/CD340), PTGS2 (Prostaglandin-endoperoxide synthase 2), and SRC (Proto-oncogene tyrosine-protein kinase). Furthermore, molecular dynamics confirmed that CCND1 and EGFR are the potential targets of ricobendazole for the treatment of LC. BBA can be further explored as a therapeutic strategy for the treatment of lung cancer under in vitro and in vivo studies.Communicated by Ramaswamy H. Sarma.

A Systematic Review on Interferon Alpha-Induced Cognitive Impairment in Hepatitis C Patients.

OBJECTIVE: Interferon-alpha (IFN-α) is an important treatment modality for the hepatitis C virus (HCV). However, treatment with IFN-α is often associated with cognitive difficulties in HCV patients. Thus, this systematic review was performed to assess the effects of IFN-α on cognitive functioning in patients suffering from HCV. METHODS: Relevant literature was identified by performing a comprehensive literature search in major databases including PubMed, clinicaltrials.gov, and Cochrane Central using a combination of suitable keywords. We retrieved studies that were published from the start of each database until August 2021. RESULTS: Out of 210 articles, 73 studies were selected after removing the duplicates. In the first pass, 60 articles were excluded. Out of 13 full-text articles, only 5 articles qualified for qualitative analyses in the second pass. We observed conflicting results concerned with the use of IFN-α and the risk of neurocognitive impairment in HCV patients. CONCLUSION: In conclusion, we have observed conflicting results regarding the impact of INF-α treatment on the cognitive functioning of patients suffering from HCV. Thus, there is an urgent need for an extensive study to evaluate the exact association between INF-αtherapy and cognitive functioning in HCV patients.

Role of Cytokines in Chemotherapy-related Cognitive Impairment of Breast Cancer Patients: A Systematic Review.

BACKGROUND: Cognitive impairment is one of the most common problems experienced by patients receiving chemotherapy, and evidence suggests that cytokines might play an important role. Various studies were conducted to evaluate the role of cytokines in chemotherapy-related cognitive impairment (CRCI). However, the association between CRCI due to cytokines is not well-established. Thus, this systematic review aims to assess the role of cytokines in CRCI in breast cancer patients. METHODS: This systematic review was conducted according to the Preferred Reporting Item for Systematic Review and Meta-analysis (PRISMA) guidelines. An intense literature search was carried out for inclusion criteria in major databases, including PubMed and Clinicaltrials.gov, in August 2021. Studies assessing cognitive parameters through objective and subjective assessment in breast cancer patients receiving chemotherapy were included. RESULTS: A total of 4052 studies were identified, and 15 studies were included in this systematic review. We found that IL-6, IL-1ß, and TNF-α were associated with varying degrees of cognitive impairment in breast cancer patients receiving chemotherapy. CONCLUSION: This systematic review showed a correlation between various cytokines and chemotherapy- associated cognitive decline in breast cancer patients.
