Bing-Neel syndrome, a rare manifestation of WM; a case report and review of literature.

Bing-Neel syndrome (BNS) is a rare manifestation in individuals suffering from Waldenström macroglobulinemia (WM). Neurological signs and symptoms in this syndrome are almost difficult to be differentiated from other common neurological manifestations of hyper-viscosity or Waldenström-associated polyneuropathy. In this paper, we report a new case of WM with concurrent BNS, then review the clinical picture and treatment of this syndrome.

Xenopus as a model system for studying pigmentation and pigmentary disorders.

Human pigmentary disorders encompass a broad spectrum of phenotypic changes arising from disruptions in various stages of melanocyte formation, the melanogenesis process, or the transfer of pigment from melanocytes to keratinocytes. A large number of pigmentation genes associated with pigmentary disorders have been identified, many of them awaiting in vivo confirmation. A more comprehensive understanding of the molecular basis of pigmentary disorders requires a vertebrate animal model where changes in pigmentation are easily observable in vivo and can be combined to genomic modifications and gain/loss-of-function tools. Here we present the amphibian Xenopus with its unique features that fulfill these requirements. Changes in pigmentation are particularly easy to score in Xenopus embryos, allowing whole-organism based phenotypic screening. The development and behavior of Xenopus melanocytes closely mimic those observed in mammals. Interestingly, both Xenopus and mammalian skins exhibit comparable reactions to ultraviolet radiation. This review highlights how Xenopus constitutes an alternative and complementary model to the more commonly used mouse and zebrafish, contributing to the advancement of knowledge in melanocyte cell biology and related diseases.

Delving into the Metabolism of Sézary Cells: A Brief Review.

Primary cutaneous lymphomas (PCLs) are a heterogeneous group of lymphoproliferative disorders caused by the accumulation of neoplastic T or B lymphocytes in the skin. Sézary syndrome (SS) is an aggressive and rare form of cutaneous T cell lymphoma (CTCL) characterized by an erythroderma and the presence of atypical cerebriform T cells named Sézary cells in skin and blood. Most of the available treatments for SS are not curative, which means there is an urgent need for the development of novel efficient therapies. Recently, targeting cancer metabolism has emerged as a promising strategy for cancer therapy. This is due to the accumulating evidence that metabolic reprogramming highly contributes to tumor progression. Genes play a pivotal role in regulating metabolic processes, and alterations in these genes can disrupt the delicate balance of metabolic pathways, potentially contributing to cancer development. In this review, we discuss the importance of targeting energy metabolism in tumors and the currently available data on the metabolism of Sézary cells, paving the way for potential new therapeutic approaches aiming to improve clinical outcomes for patients suffering from SS.

The effect of conjugated linoleic acid supplementation in comparison with omega-6 and omega-9 on lipid profile: a graded, dose-response systematic review and meta-analysis of randomized controlled trials.

Conjugated linoleic acid (CLA) is a geometrical isomer of linoleic acid, which has anti-inflammatory, anti-diabetic, anti-cancer, and anti-obesity properties. However, the studies reported inconstant results about the CLA-related effects on lipid profiles. As a result, meta-analysis and systematic review were performed to survey the CLA supplementation-related effect on lipid profile including high-density lipoprotein (HDL), low-density lipoprotein (LDL), total cholesterol (TC), and triglycerides (TG). To identify the relevant research, a systematic comprehensive search was initiated on the medical databases such as Scopus and PubMed/Medline until December 2022. The overall effect size was estimated by weighted mean difference (WMD) and 95% confidence interval (CI) in a random effect meta-analysis. In the final quantitative analysis, the meta-analysis considered 35 randomized controlled trials (RCTs) with 1,476 participants (707 controls and 769 cases). The pooled results demonstrated that CLA supplementation, compared with olive oil, significantly increased serum TG levels (WMD: 0.05 mmol/L; 95% CI: 0.01 to 0.1; p = 0.04; I2 = 0.0%, p = 0.91). With regard to TC level, CLA supplementation compared with placebo significantly reduced TC concentrations (WMD: -0.08 mmol/L; 95% CI: -0.14 to -0.02; p < 0.001; I2 = 82.4%). Moreover, the non-linear dose-response analysis indicated a decreasing trend of TC serum level from the 15th week of CLA supplementation compared with olive oil (Pnon-linearity = 0.01). The present meta-analysis and systematic review of 35 RCTs showed that the CLA intervention was able to raise the level of TG in comparison to olive oil; however, it can decrease TC level compared with placebo and olive oil.

Investigation of Fibroblast Growth Factor Peptide Antagonist on Mouse Model Breast Tumor through ERK/MAPK and PI3K/AKT Signaling Pathways.

BACKGROUND: In the majority of cancers, metastasis of tumor cells is the main cause of treatment failure. This study intended to investigate the effectiveness of basic fibroblast growth factor (bFGF) peptide designed to inhibit tumor growth in 4T1 metastatic breast cancer through the PI3K/AKT and ERK/MAPK signal transduction pathways. METHODS: The tumor was induced through 4T1 tumor graft in BALB/c mice. The designed peptide was injected intraperitoneal at three selected doses after two weeks for 14 days. The PBS and doxorubicin were used as the negative and positive control groups, respectively. Tumor size was measured and after the treatment period, the mice underwent a surgery and tumors were used for the western blot examinations. RESULTS: the peptide injection was effective in reducing or inhibiting tumor growth in mice model and in vitro. The western blot analysis results showed that the p-AKT and p-ERK levels in peptide treated tumors were reduced (p<0.05). CONCLUSION: The peptide injection was effective in mice model. Findings showed that in the two signal transduction pathways, the p-AKT and p-ERK levels were significantly different from the negative control group.

A new eco-friendly and water-resistant sunscreen agent: Lecithin-based multilamellar liposomes.

BACKGROUND: UV skin exposure is an important matter of public health, as the worldwide rising prevalence of skin cancers indicates. However, a wide majority of commercially available sunscreens are responsible for ocean ecosystem damages such as coral reef degradation and phytoplankton mortality. AIMS: To answer the urge for new eco-friendly UV filters, we studied the use of lecithin-based multilamellar liposomes (MLLs) of controlled size and elasticity as a bio-sourced and biodegradable alternative to classic sunscreens. These parameters control allows different skin layers targeting. METHODS: The performance of two different MLLs compositions and a commercially available SPF50+ water-resistant liposomal sunscreen was compared on skin explants. SC-MLLs target the stratum corneum and Epi-MLLs the whole epidermis. Preparations were applied prior to skin irradiation. Their efficiencies were evaluated histologically (hematoxylin and eosin staining plus cyclobutane pyrimidine dimer [CPD] immunostaining) and by skin barrier quality assessment (trans-epithelial electrical resistance). Adhesiveness to the skin was also investigated. RESULTS: Altogether, ex vivo results indicate MLLs offer a solar protection as effective as a SPF50+ water-resistant liposomal sunscreen but with a better skin adhesiveness and an improved skin barrier function. CONCLUSION: Lecithin-based MLLs of controlled physicochemical parameters can be used as a new eco-friendly and water-resistant agent for solar protection. The stratum corneum targeted action of SC-MLLs appears to be more interesting, as SC-MLLs exhibit an overall better performance than Epi-MLLs at a lower cost. The skin barrier improvement showcased could be of interest to people suffering from dry skin or skin barrier impairment related disease.

Maintenance therapy with Everolimus in patients with refractory or relapsing Hodgkin lymphoma after autologous stem cell transplantation.

Introduction: Patients with relapsing or primary refractory Hodgkin lymphoma, still have unsatisfactory outcomes after high dose chemotherapy followed by autologous stem cell transplantation (ASCT). Brentuximab Vedotin (BV) is the only approved agent for maintenance therapy for up to one year in these patients, however, this agent is often not available or affordable for many patients, especially in the developing countries. In this study, we used Everolimus as maintenance therapy after ASCT among patients with relapsing/refractory Hodgkin lymphoma. Materials and Methods: We collected the data of 20 patients with primary refractory or relapsing Hodgkin lymphoma who had undergone ASCT between June 2016 and June 2021. Everolimus was started at 10 mg daily on day +90 after ASCT for at least two years in patients with stable disease status, confirmed by imaging modalities. Patients were followed for disease status and drug side effects every 3 months. Results: In our single-arm case-series study, the median duration of treatment was 22.95 months. Except for three patients, who had progression, others had no progression and are still receiving Everolimus (85%). No serious side effect was seen. We had no mortality due to disease recurrence. Conclusion: Until now, results showed promising effects of Everolimus in patients with relapsing or primary refractory Hodgkin lymphoma as maintenance therapy after ASCT.

Neoadjuvant chemotherapy outcome with taxane-based versus non-taxane protocols in gastric cancer.

BACKGROUND: Gastric cancer is the fifth most common cancer worldwide. One of the chemotherapy agents, taxanes is important in increasing patients' survival. The purpose of this study is to assess the efficacy of taxane-based drugs versus non-taxanes in neoadjuvant chemotherapy in non-metastatic gastric adenocarcinoma (GA) in Iranian patients. MATERIALS AND METHODS: In a historical cohort method, 65 patients between 18 and 75 years old who suffered from non-metastatic GA were included. Nineteen and 21 and 25 patients, had undergone DCF (docetaxel, cisplatin, 5fluorouracil) and FLOT (5fluorouracil, leucovorin, oxaliplatin, docetaxel) and FOLFOX6 (oxaliplatin, leucovorin, 5fluorouracil) regimens, respectively, between 2018 and 2021. Survival criteria consisting of progression-free survival (PFS), overall survival (OS), progression rate, and mortality rate were evaluated using the Kaplan-Meier method, in a three-year follow-up period. RESULTS: The majority of patients were male (72.3%), with a median age of 65 years. Most of the patients had lesions with tumor, node, metastasis (TNM) stage IIIb (27.7%) and poor differentiated pathological grade (49.2%). OS time had a significant correlation with the low TNM stage (P = 0.01), well-differentiated pathological grade (P = 0.005), and FLOT vs. FOLFOX protocol (20.3 vs. 12.2 months, respectively. P =0.04). FLOT regimen had significantly better OS survival vs. DCF regimen (20.3 vs. 15.4 months, respectively, P = 0.03). No significant correlation was observed between survival criteria and other factors like gender, age, past medical history, Karnofsky scale, and tumor location in the stomach. The taxane-based arm (sum of DSF and FLOT) had no superiority over the non-taxane arm in survival criteria. CONCLUSION: FLOT protocol, as a taxane-based regimen had better survival compared to FOLFOX protocol in neoadjuvant chemotherapy in gastric non-metastatic adenocarcinoma.

The E3 ubiquitin ligase FBXL6 controls the quality of newly synthesized mitochondrial ribosomal proteins.

In mammals, about 99% of mitochondrial proteins are synthesized in the cytosol as precursors that are subsequently imported into the organelle. The mitochondrial health and functions rely on an accurate quality control of these imported proteins. Here, we show that the E3 ubiquitin ligase F box/leucine-rich-repeat protein 6 (FBXL6) regulates the quality of cytosolically translated mitochondrial proteins. Indeed, we found that FBXL6 substrates are newly synthesized mitochondrial ribosomal proteins. This E3 binds to chaperones involved in the folding and trafficking of newly synthesized peptide and to ribosomal-associated quality control proteins. Deletion of these interacting partners is sufficient to hamper interactions between FBXL6 and its substrate. Furthermore, we show that cells lacking FBXL6 fail to degrade specifically mistranslated mitochondrial ribosomal proteins. Finally, showing the role of FBXL6-dependent mechanism, FBXL6-knockout (KO) cells display mitochondrial ribosomal protein aggregations, altered mitochondrial metabolism, and inhibited cell cycle in oxidative conditions.

Retroperitoneal lymphangioma as the final diagnosis of a middle-aged woman with abdominal pain: a case report.

BACKGROUND: Lymphangiomas are lesions attributed to congenital malformations of the lymphatic system, or acquired chronic obstruction of the lymphatic network due to trauma, radiation, surgical manipulation, inflammation, or infection. Overall, lymaphangiomas are rare, and particularly, retroperitoneal lymphangiomas are far more uncommon per reported cases. CASE PRESENTATION: A 49-year-old Iranian woman presented with a progressive abdominal pain since approximately 1 month before admission. She was found to have a retroperitoneal lymphangioma after a precise radiological and surgical workup. CONCLUSION: Retroperitoneal lymphangiomas are rare lesions, sometimes indistinguishable from malignant lesions originating from pancreas and adjacent organs. Complete surgical removal and histologic evaluation of the lesion is the gold standard of treatment and diagnosis.

Xenopus: An in vivo model for studying skin response to ultraviolet B irradiation.

Ultraviolet B (UVB) in sunlight cause skin damage, ranging from wrinkles to photoaging and skin cancer. UVB can affect genomic DNA by creating cyclobutane pyrimidine dimers (CPDs) and pyrimidine-pyrimidine (6-4) photoproducts (6-4PPs). These lesions are mainly repaired by the nucleotide excision repair (NER) system and by photolyase enzymes that are activated by blue light. Our main goal was to validate the use of Xenopus laevis as an in vivo model system for investigating the impact of UVB on skin physiology. The mRNA expression levels of xpc and six other genes of the NER system and CPD/6-4PP photolyases were found at all stages of embryonic development and in all adult tissues tested. When examining Xenopus embryos at different time points after UVB irradiation, we observed a gradual decrease in CPD levels and an increased number of apoptotic cells, together with an epidermal thickening and an increased dendricity of melanocytes. We observed a quick removal of CPDs when embryos are exposed to blue light versus in the dark, confirming the efficient activation of photolyases. A decrease in the number of apoptotic cells and an accelerated return to normal proliferation rate was noted in blue light-exposed embryos compared with their control counterparts. Overall, a gradual decrease in CPD levels, detection of apoptotic cells, thickening of epidermis, and increased dendricity of melanocytes, emulate human skin responses to UVB and support Xenopus as an appropriate and alternative model for such studies.

Does folic acid supplementation have a positive effect on improving memory? A systematic review and meta-analysis of randomized controlled trials.

Introduction: The results of randomized controlled trials (RCTs) on the effect of folic acid supplementation on memory status due to various heterogeneity, dosage, duration, and cognitive function assessments were inconclusive. Therefore, we have performed a systematic review and meta-analysis to investigate the effect of folic acid supplementation on memory in RCTs. Method: Comprehensive computerized systematic searches were conducted throughout Scopus, PubMed/Medline, and Google Scholar from inception until February 2022 to investigate the effect of folic acid supplementation memory levels in RCTs. The standardized mean difference (SMD) and 95% confidence interval (CIs) were used to estimate the overall effect size using random-effects meta-analyses. Results: The overall results of nine trials with 641 participants, revealed that folic acid supplementation did not significantly change memory score compared to placebo (SMD: 0.12; 95% CI: -0.17, 0.40, p = 0.418; I 2 = 62.6%). However, subgroup analyses showed that supplementation with folic acid had favorable effects on memory levels considering the following conditions: (1) doses lower than 1 mg/day, (2) treatment lasting more than 6 months, (3) conducted in eastern countries, and (4) in participants equal to or older than 70 years old. The dose-response analysis suggested a significant favorable effect on memory status at doses of 6-11 mg/d and a significant decline at doses of 17-20 mg/d. Discussion: Although we did not find a significant effect of folic acid supplementation on memory, there were some suggestions of beneficial effects in the subgroup analyses.

The nine-month PFS was 69.2%. Total survival was 16.7 months (CI95%:13.5-19.9). Conclusion: Ultimately, according to the obtained results, it may be concluded that the therapeutic response to ramucirumab + folfiri in a patient with metastatic gastric cancer is good, and the use of this regimen is recommended.

Predictors of Weight Regain and Insufficient Weight Loss According to Different Definitions After Sleeve Gastrectomy: a Retrospective Analytical Study.

BACKGROUND: Weight regain (WR) and insufficient weight loss (IWL) after sleeve gastrectomy (SG) are challenging issues. This study aimed to evaluate the predictors of WR and IWL after SG. METHODS: In this retrospective analytical study, 568 patients who underwent SG at Hazrat-e Rasool General Hospital, Tehran, Iran, between January 2015 and April 2022 were evaluated. A total of 333 patients were included. WR and IWL were evaluated by multiple criteria such as a BMI of > 35 kg/m2, an increase in BMI of > 5 kg/m2 above nadir, an increase in weight of > 10 kg above nadir, percentage of excess weight loss (%EWL) < 50% at 18 months, an increase in weight of > 25% of EWL from nadir at 36 months, and percentage of total weight loss (%TWL) < 20% at 36 months. All participants were followed up for 36 months. RESULT: The univariate analysis showed that preoperative BMI, obstructive sleep apnea, metformin consumption, and grades 2 and 3 fatty liver disease were associated with WR and IWL (P < 0.05). WR or IWL incidence varied (0-19.3%) based on different definitions. The multivariate analysis showed that a preoperative BMI of > 45 kg/m2 [odds ratioAdjusted (ORAdj) 1.77, 95% CI: 1.12-4.11, P = 0.038] and metformin consumption [ORAdj: 0.48, 95% CI: 0.19-0.78, P = 0.001] were associated with WR and IWL after SG, regardless of the definition of WR or IWL. CONCLUSION: This study showed that preoperative BMI of > 45 kg/m2, obstructive sleep apnea, metformin consumption, and grades 2 and 3 of fatty liver disease were associated with WR or IWL.

Thoracic Sarcoma: A New Glance at the Epidemiological Characteristics of Disease in Iran from 2009 to 2014.

Background: The heterogeneity, high rate of mortality and lack of comprehensive diagnostic methods have categorized primary sarcomas of the thorax as a malignancy with dismal outcomes and unknown etiology. Given the fundamental role of epidemiological analysis in establishing management strategies, we designed a study with focus on the epidemiological characteristics of primary thoracic sarcomas in Iran. Methods: This national population-based cancer study was conducted on patients with histologically confirmed sarcoma of the thorax referred to the Iranian National Cancer Registry between 2009 and 2014. The incidence was calculated as number of cases per 100,000 person-years and was age-adjusted by the direct method using the weight of the 1960 world standard population. Results: Over a 6-year period, 1477 cases with pathologically confirmed thoracic sarcomas were registered in Iran, of which 896 were male and 581 were female. Khuzestan Province had the highest incidence of thoracic sarcomas as compared to other provinces. Malignant mesothelioma was the most common histological subtype (20.85%). Moreover, the age-standardized incidence rate (ASR) of the disease was 1.94 per 100,000 which was more common in males than females with the highest incidence rate in men aged more than 65 years. Conclusion: Our study provided valuable epidemiologic data on characteristics of thoracic sarcomas. This data can be used for strategizing preventive measures.

Does Ashwagandha supplementation have a beneficial effect on the management of anxiety and stress? A systematic review and meta-analysis of randomized controlled trials.

Clinical trial studies revealed conflicting results on the effect of Ashwagandha extract on anxiety and stress. Therefore, we aimed to evaluate the effect of Ashwagandha supplementation on anxiety as well as stress. A systematic search was performed in PubMed/Medline, Scopus, and Google Scholar from inception until December 2021. We included randomized clinical trials (RCTs) that investigate the effect of Ashwagandha extract on anxiety and stress. The overall effect size was pooled by random-effects model and the standardized mean difference (SMD) and 95% confidence interval (CIs) for outcomes were applied. Overall, 12 eligible papers with a total sample size of 1,002 participants and age range between 25 and 48 years were included in the current systematic review and meta-analysis. We found that Ashwagandha supplementation significantly reduced anxiety (SMD: -1.55, 95% CI: -2.37, -0.74; p = .005; I2  = 93.8%) and stress level (SMD: -1.75; 95% CI: -2.29, -1.22; p = .005; I2  = 83.1%) compared to the placebo. Additionally, the non-linear dose-response analysis indicated a favorable effect of Ashwagandha supplementation on anxiety until 12,000 mg/d and stress at dose of 300-600 mg/d. Finally, we identified that the certainty of the evidence was low for both outcomes. The current systematic review and dose-response meta-analysis of RCTs revealed a beneficial effect in both stress and anxiety following Ashwagandha supplementation. However, further high-quality studies are needed to firmly establish the clinical efficacy of the plant.

XPC multifaceted roles beyond DNA damage repair: p53-dependent and p53-independent functions of XPC in cell fate decisions.

Xeroderma pigmentosum group C protein (XPC) acts as a DNA damage recognition factor for bulky adducts and as an initiator of global genome nucleotide excision repair (GG-NER). Novel insights have shown that the role of XPC is not limited to NER, but is also implicated in DNA damage response (DDR), as well as in cell fate decisions upon stress. Moreover, XPC has a proteolytic role through its interaction with p53 and casp-2S. XPC is also able to determine cellular outcomes through its interaction with downstream proteins, such as p21, ARF, and p16. XPC interactions with effector proteins may drive cells to various fates such as apoptosis, senescence, or tumorigenesis. In this review, we explore XPC's involvement in different molecular pathways in the cell and suggest that XPC can be considered not only as a genomic caretaker and gatekeeper but also as a tumor suppressor and cellular-fate decision maker. These findings envisage that resistance to cell death, induced by DNA-damaging therapeutics, in highly prevalent P53-deficent tumors might be overcome through new therapeutic approaches that aim to activate XPC in these tumors. Moreover, this review encourages care providers to consider XPC status in cancer patients before chemotherapy in order to improve the chances of successful treatment and enhance patients' survival.

Is Infantile Hemangioma a Neuroendocrine Tumor?

Infantile hemangioma (IH) is the most common infantile tumor, affecting 5-10% of newborns. Propranolol, a nonselective ß-adrenergic receptor (ADRB) antagonist, is currently the first-line treatment for severe IH; however, both its mechanism of action and its main cellular target remain poorly understood. Since betablockers can antagonize the effect of natural ADRB agonists, we postulated that the catecholamine produced in situ in IH may have a role in the propranolol response. By quantifying catecholamines in the IH tissues, we found a higher amount of noradrenaline (NA) in untreated proliferative IHs than in involuted IHs or propranolol-treated IHs. We further found that the first three enzymes of the catecholamine biosynthesis pathway are expressed by IH cells and that their levels are reduced in propranolol-treated tumors. To study the role of NA in the pathophysiology of IH and its response to propranolol, we performed an in vitro angiogenesis assay in which IH-derived endothelial cells, pericytes and/or telocytes were incorporated. The results showed that the total tube formation is sensitive to propranolol only when exogenous NA is added in the three-cell model. We conclude that the IH's sensitivity to propranolol depends on crosstalk between the endothelial cells, pericytes and telocytes in the context of a high local amount of local NA.

Post-Marketing Surveillance of a generic Oxaliplatin (AlvoxalⓇ) in Iranian Patients with Cancer.

BACKGROUND: CRC is the second and third most common cancer in women and men, respectively. The national comprehensive cancer network guidelines recommend oxaliplatin-based chemotherapy as a preferred regimen for patients with advanced or metastatic colon cancer. Oxaliplatin is also used in the off-label treatment of gastric cancer. FDA uses post-marketing study commitments to gather additional information about a product's safety, efficacy, or optimal use. It is necessary to perform safety monitoring after marketing authorization is received; such monitoring can be done by means of characterizing the safety of drugs in patients being treated in real-world clinical practice settings. OBJECTIVES: This Phase IV study aimed to evaluate the safety profile of a brand-name formulation of the generic drug oxaliplatin (AlvoxalⓇ, NanoAlvand, Tehran, Iran) in Iranian patients diagnosed with either colorectal or other, different types of cancer. METHODS: Patients with colorectal cancer, gastric cancer, or other malignancies receiving oxaliplatin as a part of their treatment were included in this open-label, multicenter, observational Phase IV study. This study aimed to assess the safety profile of oxaliplatin in patients diagnosed with different cancers. FINDINGS: A total of 483 patients from 16 cities in Iran were enrolled. The most common malignancy was colorectal cancer (55.49%), followed by gastric cancer (28.16%). Based on the results, 405 patients experienced at least 1 adverse event. Most of these adverse events were grade 1 or 2, and the most commonly reported adverse event was anemia (60.66%). During the study, 26 serious adverse events occurred in 15 (3.11%) patients, which were perhaps related to oxaliplatin. There were no remarkable differences in the incidences of adverse events in the system organ classes of blood and lymphatic system disorders, gastrointestinal disorders, or nervous system disorders among patients with different malignancies (ie, colorectal cancer, gastric cancer, and other malignancies) or between genders. The results of this open-label, multicenter, observational, postmarketing surveillance study demonstrated no unexpected safety findings from the use of this oxaliplatin product (AlvoxalⓇ) in Iranian patients diagnosed with different types of cancer. CONCLUSIONS: This Phase IV study provides data on the safety profile of a number of chemotherapy regimens containing an oxaliplatin product given to Iranian patients diagnosed with different types of cancer.
