RESUMO

BACKGROUND: Coronary Slow Flow Phenomenon (CSFP) is a well-recognized clinical entity characterized by delayed opacification of coronary arteries in the presence of a normal coronary angiogram. The objective of this study was determined and compared left ventricle (LV)strain in patients with CSFP before and after receiving a high-dose atorvastatin. MATERIALS AND METHODS: This cross-sectional study was conducted on 51 patients with CSFP from the beginning of 2021 to the end of September 2022. Trans-thoracic Echocardiogram (TTE) was performed by an echocardiography specialist. Thereafter, the patient's basic information was entered into the researcher's checklist after treatment with atorvastatin 40 mg daily for eight consecutive weeks. After eight weeks, the patients were subjected again to TTE. The data were analyzed in SPSS statistical software. RESULTS: The mean LV-GLS before taking atorvastatin was - 16.53%±3.63%. The mean LV-GLS after taking atorvastatin was 17.57%±3.53% (P.value = 0.01). The mean LV function before taking atorvastatin was 48.82%±9.19%. Meanwhile, the mean LV function after taking atorvastatin was 50.59%±7.91% (P = 0.01). There was no significantly change in left atrium volume (49.88 ± 0.68 vs. 49.9 + 0.67) after 8 weeks taking atorvastatin (P = 0.884). CONCLUSION: The plasma ET-1 levels are elevated in CSFP patients, and atorvastatin improves coronary flow and endothelial function. As evidenced by the results of this study, the daily intake of 40 mg of oral atorvastatin during eight consecutive weeks in patients with CSFP significantly improved LV strain and LV function, however atorvastatin does not have a significant effect on improving the right ventricular function and pulmonary artery systolic pressure.

RESUMO

BACKGROUND: Post COVID-19 syndrome, also known as "Long COVID," is a complex and multifaceted condition that affects individuals who have recovered from SARS-CoV-2 infection. This systematic review and meta-analysis aim to comprehensively assess the global prevalence of depression, anxiety, and sleep disorder in individuals coping with Post COVID-19 syndrome. METHODS: A rigorous search of electronic databases was conducted to identify original studies until 24 January 2023. The inclusion criteria comprised studies employing previously validated assessment tools for depression, anxiety, and sleep disorders, reporting prevalence rates, and encompassing patients of all age groups and geographical regions for subgroup analysis Random effects model was utilized for the meta-analysis. Meta-regression analysis was done. RESULTS: The pooled prevalence of depression and anxiety among patients coping with Post COVID-19 syndrome was estimated to be 23% (95% CI: 20%-26%; I2 = 99.9%) based on data from 143 studies with 7,782,124 participants and 132 studies with 9,320,687 participants, respectively. The pooled prevalence of sleep disorder among these patients, derived from 27 studies with 15,362 participants, was estimated to be 45% (95% CI: 37%-53%; I2 = 98.7%). Subgroup analyses based on geographical regions and assessment scales revealed significant variations in prevalence rates. Meta-regression analysis showed significant correlations between the prevalence and total sample size of studies, the age of participants, and the percentage of male participants. Publication bias was assessed using Doi plot visualization and the Peters test, revealing a potential source of publication bias for depression (p = 0.0085) and sleep disorder (p = 0.02). However, no evidence of publication bias was found for anxiety (p = 0.11). CONCLUSION: This systematic review and meta-analysis demonstrate a considerable burden of mental health issues, including depression, anxiety, and sleep disorders, among individuals recovering from COVID-19. The findings emphasize the need for comprehensive mental health support and tailored interventions for patients experiencing persistent symptoms after COVID-19 recovery.

RESUMO

BACKGROUND: Interpretable machine learning (ML) for early detection of cancer has the potential to improve risk assessment and early intervention. METHODS: Data from 261 proteins related to inflammation and/or tumor processes in 123 blood samples collected from healthy persons, but of whom a sub-group later developed squamous cell carcinoma of the oral tongue (SCCOT), were analyzed. Samples from people who developed SCCOT within less than 5 years were classified as tumor-to-be and all other samples as tumor-free. The optimal ML algorithm for feature selection was identified and feature importance computed by the SHapley Additive exPlanations (SHAP) method. Five popular ML algorithms (AdaBoost, Artificial neural networks [ANNs], Decision Tree [DT], eXtreme Gradient Boosting [XGBoost], and Support Vector Machine [SVM]) were applied to establish prediction models, and decisions of the optimal models were interpreted by SHAP. RESULTS: Using the 22 selected features, the SVM prediction model showed the best performance (sensitivity = 0.867, specificity = 0.859, balanced accuracy = 0.863, area under the receiver operating characteristic curve [ROC-AUC] = 0.924). SHAP analysis revealed that the 22 features rendered varying person-specific impacts on model decision and the top three contributors to prediction were Interleukin 10 (IL10), TNF Receptor Associated Factor 2 (TRAF2), and Kallikrein Related Peptidase 12 (KLK12). CONCLUSION: Using multidimensional plasma protein analysis and interpretable ML, we outline a systematic approach for early detection of SCCOT before the appearance of clinical signs.

RESUMO

INTRODUCTION: To compare data from preoperative positron emission tomography/computed tomography (PET/CT) with results of panscopy with biopsy and ultrasound with fine needle aspiration cytology (US-FNAC) on the same patients. METHODS: In this retrospective (2014-2016) study, we compared PET/CT results with the results from panscopy with biopsy and US-FNAC in patients suspected of head and neck malignancy treated at the University Hospital in Umeå, Sweden. RESULTS: A 91.3% concordance was seen between results from PET/CT and panscopy with biopsy, whereas between PET/CT and US-FNAC the concordance was 89.1%. CONCLUSIONS: The present data show the usefulness of PET/CT in the diagnosis of head and neck malignancies.

RESUMO

The p75 neurotrophin receptor (p75NTR, also known as tumor necrosis factor receptor superfamily member 16) is implicated in diverse cellular events, but fundamental aspects of its signaling mechanisms remain unclear. To address this, we have established a novel bioassay to characterize signaling cascades activated by p75NTR. We show that in COS7 cells, p75NTR expression causes a large increase in cell surface area that relies on the activation of Rac1, and we demonstrate that the p75NTR-dependent COS7 phenotype is dependent on ADAM17- and c-secretase-dependent cleavage of p75NTR and generation of the p75NTR intracellular domain (p75NTRICD). We show that the p75NTR adaptor protein NRAGE (also known as MAGED1) acts downstream of the p75NTRICD in this cascade and, through a yeast two-hybrid screen, identify NEDD9, a Cas family adaptor protein, as a novel NRAGE-binding partner that mediates p75NTR-dependent Rac1 activation and cell spreading. Our results demonstrate a crucial role for p75NTR cleavage in small GTPase activation and define a novel Rac1 activation pathway involving the p75NTRICD, NRAGE andNEDD9.

RESUMO

The charge and discharge of lithium ion batteries are often accompanied by electrochemically driven phase-transformation processes. In this work, two in situ and operando methods, that is, micro-Raman spectroscopy and X-ray diffraction (XRD), have been combined to study the phase-transformation process in LiFePO4 at two distinct length scales, namely, particle-level scale (∼1 µm) and macroscopic scale (∼several cm). In situ Raman studies revealed a discrete mode of phase transformation at the particle level. Besides, the preferred electrochemical transport network, particularly the carbon content, was found to govern the sequence of phase transformation among particles. In contrast, at the macroscopic level, studies conducted at four different discharge rates showed a continuous but delayed phase transformation. These findings uncovered the intricate phase transformation in LiFePO4 and potentially offer valuable insights into optimizing the length-scale-dependent properties of battery materials.

RESUMO

Ag:Au alloy nanoparticles were successfully synthesized through the new route using co-reduction method with silver nitrate, chloroauric acid, cetyl trimethyl ammonium bromide (CTAB) and sodium borohydride at room temperature. The Ag:Au alloy nanoparticles were then loaded within the phosphatidylcholine (97%) liposome structure. Various molar ratios of phosphotidylcholine and CTAB to the total metals were investigated showing its importance on the stability of nanocomposites suspension. The size distribution and morphology of encapsulated nanoparticles within the liposome structure were studied via ultraviolet (UV)-visible spectrum, transmission electron microscope (TEM) micrographs, and dynamic light scattering data. The synthesis of alloy nanoparticles were confirmed with formation of single band at 430, 465 and 500 nm for 75:25, 50:50 and 25:75 Ag:Au mole ratios, respectively. The TEM micrographs of different samples indicated formation of three various nanocomposite structures with size of 82-300 nm. The antibacterial activities of Ag:Au nanocomposites were studied against Pseudomonas aeruginosa through well-diffusion agar. The minimum inhibitory concentration (MIC) and minimum bactericidal concentration (MBC) were determined by Broth microdilution method. The results showed that 10 ppm nanocomposite reasonably killed the above bacteria.

RESUMO

Idiopathic hypertrophic pachymeningitis (IHP) is a rare disease with diffuse thickening of the dura mater that has no specific clinical symptoms and manifestations and it causes neurosurgeons to misdiagnose. A 4-year-old girl presented at the emergency room of our hospital with speech difficulty and severe headache. Head computed tomography scans (CT scan) on admission revealed a large fluid collection over the right temporoparietal region with mass effect, and the neurosurgeon drained it with the initial diagnosis of subdural hematoma. However, the postoperative CT scan demonstrated the failure of surgical drainage; therefore, magnetic resonance imaging (MRI) was requested for the patient. MRI identified diffuse nodular dural thickening with internal septations and different internal hemorrhagic stages on the right side with no evidence of brain parenchymal involvement and according to the serology and autoimmune screening tests, and IHP was diagnosed for the patient. The patient underwent craniotomy. There was an immediate improvement of neurologic symptoms. The patient had good clinical and radiologic outcome at 3 -months follow-up. IHP should be part of the differential diagnosis of some cases of noncommunicating hydrocephalus; however, the rarity of the disease and the absence of specific clinical symptoms make the diagnosis difficult.

RESUMO

In this paper, a Cluster-based Synthetic minority oversampling technique (SMOTE) Both-sampling (CSBBoost) ensemble algorithm is proposed for classifying imbalanced data. In this algorithm, a combination of over-sampling, under-sampling, and different ensemble algorithms, including Extreme Gradient Boosting (XGBoost), random forest, and bagging, is employed in order to achieve a balanced dataset and address the issues including redundancy of data after over-sampling, information loss in under-sampling, and random sample selection for sampling and sample generation. The performance of the proposed algorithm is evaluated and compared to different state-of-the-art competing algorithms based on 20 benchmark imbalanced datasets in terms of the harmonic mean of precision and recall (F1) and area under the receiver operating characteristics curve (AUC) measures. Based on the results, the proposed CSBBoost algorithm performs significantly better than the competing algorithms. In addition, a real-world dataset is used to demonstrate the applicability of the proposed algorithm.

RESUMO

BACKGROUND: Liraglutide is a glucagon-like peptide-1 (GLP-1) receptor agonist used for the treatment of type 2 diabetes mellitus (T2DM). So far, few severe side effects have been reported for it. CASE PRESENTATION: A 41-year-old woman was admitted to the Emergency Room with diffuse abdominal pain. The patient had a known case of T2DM, fatty liver disease, and hypertension and was treated with Metformin, Liraglutide, and Losartan. Her liver functional test (LFT) was consistent with hepatocellular injury; however, laboratory tests and abdominal ultrasound were used to rule out autoimmune hepatitis. Due to concerns for drug-induced liver injury (DILL), liraglutide was discontinued and N-acetyl cysteine was prescribed. On the fifth day of hospitalization, the patient's symptoms resolved and his LFT started to decrease on the sixth day after 2 months, the patient's liver enzyme levels returned to normal. CONCLUSION: Liraglutide is one of the most important drugs in the treatment of T2DM.The most common side effects of this drug are constipation, nausea, vomiting, diarrhea, indigestion, and loss of appetite. In rare cases, symptoms of thyroid cancer, pancreatitis, and hypoglycemia have been reported, however, DILL is one of the extremely rare side effect of Liraglutide. It is important to increase the awareness of physicians about the liver injury of Liraglutide.

RESUMO

Enterobius vermicularis is a common parasitic infection worldwide. Acute appendicitis (AA) is a frequently encountered condition in general surgery; however, its association with E. vermicularis remains controversial. AA caused by E. vermicularis is a relatively uncommon infection that primarily affects children. We reported a 21-year-old female who was admitted to our hospital due to right lower quadrant abdominal tenderness. Laboratory tests and imaging were not consistent with AA. She underwent a diagnostic laparoscopy and appendectomy. Histopathological examinations revealed the presence of E. vermicularis in the lumen of the appendix, which caused its obstruction without evidence of inflammatory cell infiltration or lymphoid hyperplasia.

RESUMO

The present umbrella review evaluated the environmental risk factors prior to conception associated with fetal macrosomia based on meta-analyses and systematic reviews. We systematically searched international databases, including PubMed, Scopus, and Web of Science, until April 2023 by using some relevant keywords. The quality of the included studies was assessed using the AMSTAR 2checklist. The risk factor of advanced maternal age 35-39 years compared with <30 years (OR 1·42, 95 % CI: 1·25, 1·60), prepregnancy obesity (OR 1.93, 95 % CI: 1.65, 2.27) and excessive weight gain before and during pregnancy (OR 2.35, 95 % CI: 1.95, 2.85) were graded as suggestive evidence (class III). Two risk factors of advanced maternal age >40 years compared with <30 years (OR 1.40, 95 % CI: 1.02, 1.78) and gestational diabetes mellitus (GDM) without insulin use (OR 1.70, 95 % CI: 1.23, 2.36) were graded as risk factors with weak evidence (class IV). Advanced maternal age, prepregnancy obesity, excessive weight gain before and during pregnancy, and GDM without insulin use were environmental risk factors for macrosomia.

RESUMO

INTRODUCTION: Curcumin is known as a bioactive component that is found in the rhizomes of Curcuma longa. Curcumin is well known for its chemo-preventive and anticancer properties. However, its anticancer mechanism in colorectal cancer treatment is unclear, and some studies have shown that many microRNAs (miRs) could be potential targets for curcumin in colorectal cancer (CRC) treatment, so there is a need for their integration and clarification. METHODS: We systematically searched international databases, including PubMed, Scopus, and Web of Science, until July 2021 by using some relevant keywords. RESULTS: The search resulted in 87 papers, among which there were 18 related articles. Curcumin was found to cause the upregulation of miR-497, miR-200c, miR-200b, miR-409-3p, miR-34, miR-126, miR-145, miR-206, miR-491, miR-141, miR-429, miR-101, and miR-15a and the downregulation of miR-21, miR-155, miR-221, miR-222, miR-17-5p, miR-130a, miR-27, and miR-20a. CONCLUSION: The present review study suggests that curcumin may be useful as a novel therapeutic agent for CRC by altering the expression level of miRs.

RESUMO

BACKGROUND: Helicobacter pylori [H. pylori] infection is the main cause of most PUD; therefore, the eradication of H. pylori is extremely important in the treatment of PUD. There are several recommended treatment regimens suggested to eradicate this organism. AIM: This study compared the efficacy of three anti-Helicobacter pylori regimens in patients with dyspepsia or peptic ulcer disease [PUD]. OBJECTIVE: The objective of this study was to assess the efficacy of three anti-H Pylori treatments in patients based on C14 urease breath test [C-UBT] results, drug compliance, and adverse effects. METHODS: This randomized, open-label clinical trial included 136 H. Pylori-infected patients without prior treatment. Patients were randomly divided into three groups. The OAC group received 20 mg Omeprazole capsules twice a day, two 500 mg Amoxicillin capsules twice a day, and 500 mg Clarithromycin capsules twice a day for 14 days. The OAL group received 20 mg Omeprazole capsules twice a day, two 500 mg Amoxicillin capsules twice a day, and Levofloxacin 500 mg capsules twice a day for 14 days. The OAMB group received 20 mg Omeprazole capsules twice a day, two 500 mg Amoxicillin capsules twice a day, Metronidazole 500mg three times a day, and Bismuth 240 mg twice a day for 14 days. Evaluation for compliance and drug-related adverse effects were assessed at the end of two weeks. H. Pylori eradication was evaluated eight weeks after treatment using the C-UBT. RESULTS: A total of 136 patients participated in this study, and their groups were matched based on age and sex. The results of the C-UBT test showed that the eradication rate of H. Pylori was 82.2%, 91.3%, and 97.3% for the three-drug OAC, OAMB, and OAL treatment regimens, respectively. Moreover, all the regimens showed high compliance among the patients. Only OAC and OAL showed a significant difference in the H. Pylori eradication rate, and no superiority was found between OAMB and OAL or OAC therapies. CONCLUSION: The regime of OAL achieved a satisfactory rate of H. pylori infection eradication with good tolerance in patients with PUD, without any acute side effects. CLINICAL TRIAL REGISTRATION NUMBER: IRCT201605189014N100.

RESUMO

OBJECTIVE: To evaluate intraoperative factors predicting appendiceal pathology during gynecologic oncology surgery for suspected mucinous ovarian neoplasms. METHODS: We conducted a retrospective study on 225 patients with mucinous ovarian neoplasms who underwent surgery for an adnexal mass with concurrent appendectomy between 2000 and 2018. Regression analyses were used to evaluate intraoperative factors, such as frozen section of the ovarian mass and surgeon's impression of the appendix in predicting appendiceal pathology. RESULTS: Most patients (77.8%) had a normal appendix on final pathology. Abnormal appendix cases (n = 26) included: metastasis from high-grade adenocarcinoma of the ovary (n = 1), neuroendocrine tumor of the appendix (n = 4), and low-grade appendiceal mucinous neoplasms (n = 26; 23 associated with a mucinous ovarian adenocarcinoma, 2 with a benign mucinous ovarian cystadenoma, and 1 with a borderline mucinous ovarian tumor). Combining normal intraoperative appearance of the appendix with benign or borderline frozen section yielded a negative predictive value of 85.1%, with 14.9% of patients being misclassified, and 6.0% having a neuroendocrine tumor or low-grade appendiceal neoplasm. CONCLUSION: Benign or borderline frozen section of an ovarian mucinous neoplasm and normal appearing appendix have limited predictive value for appendiceal pathology. Appendectomy with removal of the mesoappendix should be considered in all cases of mucinous ovarian neoplasm, regardless of intraoperative findings.

RESUMO

Background: Autism spectrum disorder (ASD) is a neurodevelopmental disorder characterized by severe social communication deficits and stereotypical repetitive behaviors. PURPOSE: This umbrella review assessed neonatal risk factors associated with ASD using meta-analyses and systematic reviews. METHODS: We conducted a systematic search of interna- tional databases including PubMed, Scopus, and Web of Science for studies published through April 2022 utilizing pertinent keywords. A random-effects model was used to calculate the odds ratio (OR) and 95% confidence interval (CI). Substantial heterogeneity was considered at values of I2≥50%. A quality assessment of the included studies was performed using the A MeaSurement Tool to Assess Systematic Reviews (AMSTAR2) checklist. RESULTS: A total of 207,221 children with ASD and 22,993,128 neurotypical children were included. Six meta- analyses were included in this umbrella review. The factors of congenital heart disease (OR, 1.35; 95% CI, 1.17-1.52), macrosomia (OR, 1.11; 95% CI, 1.05-1.18), low birth weight (OR, 1.63; 95% CI, 1.48-1.81), very low birth weight (OR, 2.25; 95% CI, 1.79-2.83), small for gestational age (OR, 1.17; 95% CI, 1.09-1.24), jaundice (OR, 1.74; 95% CI, 1.42- 2.12), male sex (OR, 1.47; 95% CI, 1.39-1.55) and 1-minute Apgar score <7 (OR, 1.40; 95% CI, 1.26-1.55) were graded as suggestive evidence (class III). Only 3 studies reported heterogeneity (I2<50%). Based on the AMSTAR2 analysis, the methodological quality was critically low in 3 meta- analyses, low in 2, and moderate in 1. CONCLUSION: Based on these results, clinicians should consider the risk factors for ASD and screen children in clinics.

RESUMO

AIMS: This study aimed to investigate the effects of genistein, swimming exercise, and their co-treatment on heart oxidative stress, inflammation, and cardiomyopathy in ovariectomized diabetic rats. BACKGROUND: It is well-established that diabetes is a major risk factor for cardiovascular disease in both young and postmenopausal women. Genistein is a natural phytoestrogen that has estrogenic effects. Studies have shown that genistein has a positive impact on menopause, cardiovascular dis-ease, and diabetes in women. However, the impact of genistein treatment alone and in combination with exercise training on the management of cardiac disease in diabetic women after ovarian hor-mone deprivation has not been fully explored. OBJECTIVE: The objective of this study was to evaluate the effect of genistein alone or in combination with exercise training on the cardiac expression of oxidative/inflammation biomarkers (MDA, OSI, TOS, TNF- α, and NF-κB) and miRNA-133, IGF-1, and Bcl-2 in the diabetic ovariectomized rats. METHODS: A group of Wistar rats were randomly divided into seven groups, with eight rats in each group. The groups were named control, sham, ovariectomized group (OVX), OVX +diabetes (OD), OD+ genistein (1 mg/kg, eight weeks; daily SC), OD+exercise (eight weeks), and OD+ genistein+exercise (eight weeks). The rats were given a high-fat diet and low-dose streptozotocin injection to induce diabetes. After eight weeks, the rats were anesthetized, and their hearts were removed. The study assessed the effects of treatment by measuring the expression of miRNA-133 using Real-time Polymerase Chain Reaction (PCR) and the protein levels of Bcl-2, Bax, and IGF-1 using Western blotting. The study also evaluated the levels of inflammation and oxidative stress markers using ELISA. Pathological changes were also assessed using periodic acid Schiff and he-matoxylin & eosin. RESULTS: After ovariectomy, the levels of cardiac miRNA-133, IGF-1, and Bcl-2 expression were down-regulated, and the levels of MDA, OSI, TOS, TNF-α, and NF-κB were increased, with a reduced total antioxidant capacity. Diabetes had an additive effect on these factors. Genistein was found to have a positive impact on oxidative and inflammation levels, and it also increased the expression of miRNA-133, Bcl-2, and IGF-1 in rats with OD. Furthermore, the combination of genistein and exercise had a positive effect on miRNA-133, Bcl-2, and IGF-1 expression in the heart, leading to a decrease in Bax levels. The combined intervention showed a noticeable improve-ment in oxidative and inflammation conditions. Histological examination revealed some abnormal-ities in cardiac tissue, which were found to be improved with genistein and/or exercise treatments. CONCLUSION: Genistein or/and exercise as a natural replacement therapy could improve diabetic-induced cardiac complications in ovariectomized rats' hearts.

RESUMO

INTRODUCTION: The constellation of pre and perinatal predictors are introduced as predictor for autism spectrum disorders (ASD), however, the information about the direction and strength of these predictors are lacking in Western, Iran. The current study aimed to determine the pre and perinatal predictors of ASD among children in this region. METHODS: This case-control study was conducted in Hamadan, Western Iran during January to March 2022. The study included 100 children with ASD who referred to the autism center as case group. Hundred children without ASD from registration system of health service centers were selected as control group and were matched (1:1) to cases by age and place of residency. A structured questionnaire about pre and perinatal predictors of ASD was developed by an expert panel. The questionnaire was administered by interviewing the mothers of children. RESULTS: Boy gender (OR: 3.51, 95% CI: 1.74-7.10, p-value < 0.001), small for gestational age (SGA) (3.92, 1.64-9.39, 0.002), maternal diabetes (3.51, 1.03-24.95, 0.04) and family history of mental disorders (3.64, 1.18-11.27, 0.04) were identified as significant predictors in a multivariable analysis. CONCLUSION: Our study emphasizes on the importance of screening and monitoring for ASD in the boys, those with history of SGA, from mothers with history of diabetes and with family history of mental disorders. Proposing the replication of findings emphasizes the necessity of conducting studies with larger sample sizes.

RESUMO

In the present work, we used treated domestic wastewater with different pHs in self-compacting concrete (SCC) to find the effect of treated wastewater with different pHs on the workability, mechanical, and durability properties of SCC. Eight different SCC mixtures were designed, including two control samples using tap water with a water-to-cement ratio (W/C) of 0.5 with 400 kg/m3 of cement and W/C of 0.36 with 440 kg/m3 of cement. Six SCC samples with the same characteristics as control samples except using treated domestic treated wastewater with different pHs. The results indicate that the workability of the SCC sample using the treated domestic wastewater in acidic pH was higher than the alkalinity state. Using treated domestic wastewater instead of tap water in SCC samples decreased compressive, flexural strength, and fracture toughness by less than 10%. Also, carbonation, 30-min water adsorption, and capillary water adsorption of SCC samples increased when treated domestic wastewater was used. The compressive strength of SCC samples made with treated domestic wastewater in an acidic state is less than about 5% in an alkaline state. The energy dispersive spectroscopy and the scanning electron microscope images confirmed that using treated wastewater instead of tap water, in SCC samples, reduced compressive strength because the Ca/Si ratio increased when treated domestic wastewater was used. The SCC samples with treated domestic wastewater in the alkaline state have a lower Ca/Si ratio. The higher compressive strength belongs to concrete samples that used treated domestic wastewater in an alkaline environment with a lower Ca/Si ratio.

RESUMO

Locoregional recurrences and distant metastases are major problems for patients with squamous cell carcinoma of the head and neck (SCCHN). Because SCCHN is a heterogeneous group of tumours with varying characteristics, the present study concentrated on the subgroup of squamous cell carcinoma of the oral tongue (SCCOT) to investigate the use of machine learning approaches to predict the risk of recurrence from routine clinical data available at diagnosis. The approach also identified the most important parameters that identify and classify recurrence risk. A total of 66 patients with SCCOT were included. Clinical data available at diagnosis were analysed using statistical analysis and machine learning approaches. Tumour recurrence was associated with T stage (P=0.001), radiological neck metastasis (P=0.010) and diabetes (P=0.003). A machine learning model based on the random forest algorithm and with attendant explainability was used. Whilst patients with diabetes were overrepresented in the SCCOT cohort, diabetics had lower recurrence rates (P=0.015 after adjusting for age and other clinical features) and an improved 2-year survival (P=0.025) compared with non-diabetics. Clinical, radiological and histological data available at diagnosis were used to establish a prognostic model for patients with SCCOT. Using machine learning to predict recurrence produced a classification model with 71.2% accuracy. Notably, one of the findings of the feature importance rankings of the model was that diabetics exhibited less recurrence and improved survival compared with non-diabetics, even after accounting for the independent prognostic variables of tumour size and patient age at diagnosis. These data imply that the therapeutic manipulation of glucose levels used to treat diabetes may be useful for patients with SCCOT regardless of their diabetic status. Further studies are warranted to investigate the impact of diabetes in other SCCHN subtypes.
