ABSTRACT

Background and objective Given its ever-increasing burden, chronic kidney disease (CKD) represents a significant public health threat. CKD is characterized by a gradual alteration in the kidney's normal glomerular filtration rate, which results in the progressive loss of kidney function over a period of time ranging from a few months to years. Diabetes mellitus (DM) and hypertension (HTN) are well-known risk factors for developing CKD and end-stage renal failure. In light of this, this study aimed to assess the awareness, prevalence, and risk factors of CKD in patients with diabetes and those with HTN in the Aseer region, the Kingdom of Saudi Arabia. Methods A correlational cross-sectional study was conducted among a sample of people across Saudi Arabia. The data collection was conducted via an online questionnaire circulated on social media platforms. The study questionnaire included socioeconomic and demographic information and medical history of DM, HTN, and CKD. Also, patients' awareness of and attitude towards CKD were assessed. Results A total of 301 diabetic or hypertensive patients fulfilling the inclusion criteria completed the study questionnaire. Of them, 174 (57.8%) were aged less than 55 years, while 127 (42.2%) were aged more than 55 years; 200 (66.4%) patients were males. A total of 94 (31.2%) study patients were diabetic, 64 (21.3%) were hypertensive, and 143 (47.5%) were both diabetic and hypertensive; 226 (75.1%) study patients had an overall good awareness of CKD while only 75 (24.9%) showed a poor awareness level. Higher awareness was associated with patients' age, education, and having CKD, DM, or HTN (p<0.05). Conclusion Our findings revealed that CKD was not common among study patients, and its prevalence was found to be less than estimated based on many studies in the literature. Also, diabetic and hypertensive patients showed a higher than satisfactory level of awareness of CKD, especially young patients with high levels of education.

ABSTRACT

INTRODUCTION: Oxaliplatin utilized in colorectal neoplasms treatment could induce acute peripheral neuropathy (APN) which is a dreadful and frequent adverse event. The objective of this study is to estimate incidence of APN induced by oxaliplatin cumulative incidence in cancer patients colorectal and to describe the distribution of the APN incidence according to demographic and clinical characteristics, as well as according to oxaliplatin cumulative dose. MATERIAL AND METHODS: This is a prospective descriptive study which took place from June to December 2018 at the Salah Azaiz Institute, Tunis. Demographic data, clinical data and data on oxaliplatin administration were collected from patient interview, medical files and pharmaceutical databases. RESULTS: The APN (grade 1, grade 2 and grade 3) cumulative incidence during the period of six months of follow up was 86% (95% CI [0.7815-0.9132]). While 38.3% (95% CI [0.29-0.48]) of the patients had grade 2 or 3 neuropathy. The search for factors associated with the risk of grade 2 and 3 NAP revealed trend significant association with diabetes (adjusted RR = 5.7 (IC95% [0.9- 37.3]; p = 0.07). Moreover, there was significant association with oxaliplatin cumulative dose (≥421 mg/m2) to increase the risk of APN grade 2 and 3 (adjusted RR = 7.8; [2.7-22.7]; p = 0.0001). Furthermore, significant association with obesity to increase the risk of APN grade 2 and 3 (adjusted RR = 5.3 [1.1- 25.4]; p = 0.04) was found. Among the patients included, 31.1% experienced oxaliplatin dose reduction and in the majority of cases this reduction is due to neurotoxicity (90.9%). CONCLUSION: The high incidence of oxaliplatin-induced APN remains an embarrassing and handicapping side effect. Our study has shown that oxaliplatin cumulative dose (≥421 mg/m2), diabetes and obesity are risk factor for the development of grade 2 and 3 APN.

ABSTRACT

INTRODUCTION: Cardiotoxicity is the most important side effect of Trastuzumab treatment. The purpose of this study is to evaluate the prevalence of Trastuzumab induced cardiotoxicity and to analyze risk factors associated with this side effect. MATERIALS AND METHODS: A retrospective institutional study was carried out from June 2018 to December 2018 at the department of Medical Oncology of Salah Azaiz institute, Tunis, Tunisia. Demographic, clinical characteristics (menopausal status, breast cancer stage, anthracyclines exposure, comorbidities presence…) and left ventricular ejection function (LVEF) measurements, were collected from patient records. RESULTS: Twenty-three women (20%) had Trastuzumab induced cardiotoxicity.65.2% (N = 15) experienced a decrease in LVEF more than 10% with a decrease below normal value and 34.8% (N = 8) experienced a decrease in LVEF more than 20%. Obesity is a risk factor for the occurrence of Trastuzumab induced cardiotoxicity (adjusted odds ratio (OR) = 2.919 (95% confidence interval (CI) [1.0411-8.186]; p = 0.042). CONCLUSION: Our study highlighted that obesity is associated with a high risk of cardiotoxicity in women treated with Trastuzumab. Therefore, close monitoring of cardiac function is recommended especially for obese women during Trastuzumab administering.

ABSTRACT

INTRODUCTION: The use of complementary and alternative medicine (CAM) among cancer patients is prevalent worldwide as cancer patient are perpetually seeking for a way to improve their quality of life and to cure their disease. Unfortunately, the majority ignore the danger that can resort when they use CAM currently with conventional therapies. The purpose of this study is to assess prevalence and predictors of CAM use in cancer patients. METHODS: Cross-sectional study using a questionnaire administered to cancer patients, who were attending Salah Azaiz institute, Tunis, Tunisia. The study took place from September to December 2018. RESULTS: In 222 cancer patients, the overall prevalence of CAM use was 40.54%. On univariate analysis, patients who had university education level were less likely to use CAM (p = 0.05). Based on multivariate analysis, CAM users had more likely metastatic tumor (p = 0.047; OR = 1.913).It is reported that the majority of the population used herbal medicine. The most common herbal products consuming by patients, included Ephedra foeminea (51.8%), Annona muricata (12%) and Curcuma longa L. (10.84%).The main source of information was entourage (family, friends, hospital entourage) (74.44%).The majority of CAM users (61.11%) reported to consume CAM currently with conventional therapies. CONCLUSION: This survey revealed a high prevalence of CAM use. The most common type of CAM use is herbal products. Some of the used herbal products are known to interact with conventional anticancer medication. This emphasizes the importance of patients disclosure of CAM use to health professionals in order to avoid herb-medications interactions.

ABSTRACT

BACKGROUND: Osteosarcoma is the most frequent bone cancer occurring in children and adolescents aged 10-20 years. Several prognostic factors have been identified by studies done at western centers. The aim of our study was to identify the prognostic factors in Tunisian patients in order to improve their management. METHODS: We reviewed the data of localized limb osteosarcoma patients treated in Salah Azaïz Institute from January 1980 to December 2018. Patient's treatment and survival variables were assessed. Patients received a neoadjuvant chemotherapy and underwent surgery in an expert center. They received afterward an adjuvant chemotherapy depending on the tumor necrosis assessed by Huvos. RESULTS: Eighty-five patients were enrolled. Mean duration of follow-up was 30 months (range 1-297 months). Males were 1.6 times more frequent, median age was 17 (from 1 to 62 years). Conventional osteoblastic osteosarcoma was the most frequent histological subtype (77%). Median tumor size was 10 cm. Femoral location was the most frequent (60%). The overall average history of symptoms was 103 days (4 to 423 days). The 5-year overall-survival was 38% and the event free survival 32%. Tumor site, lactate dehydrogenase levels, high methotrexate levels at 24 h, clinical evaluation of the tumor perimeter, surgery type and delay of relapse were found to affect overall survival. Tumor site, Lactate dehydrogenase levels and clinical evaluation of the tumor perimeter affected the progression free survival. CONCLUSION: Demographic characteristics of Tunisian patients are mainly the same than worldwide. Femoral site, normal level of lactate dehydrogenase, a clinical response during neoadjuvant treatment, an R0 surgery, a delay of relapse over 2 years and Median H24 Methotrexate level superior to 4.4 µmol/l were associated with a better prognosis in our study.

ABSTRACT

COVID-19 is an exceptional public healthcare emergency that affected all countries. The corona virus pandemic has made the treatment of all cancers difficult. This international phenomenon represents an outbreak in medicine and this situation is a major issue for all patients, whether they are infected with the virus or not. Colorectal cancer is one of the most common malignant tumors of the digestive tract which needs special multidisciplinary care. Treatment modalities including chemotherapy and targeted therapies can weaken the immune system and then cause serious or lethal coronavirus infections. This document gives an idea about how we dealt to protect patients with colorectal cancer at Salah Azaiez Institute during COVID 19 pandemic.

ABSTRACT

Cancer patients are at higher risk to be infected with COVID-19 and to develop a more severe form. Breast cancer (BC) treatments, including chemotherapy (CT), targeted therapy and immunotherapy can weaken the immune system and possibly cause lung problems. For all these reasons Salah Azaiez Institute's department of Medical Oncology took drastic actions to protect patients. In this article we will discuss protocol adjustments taken during the COVID-19 pandemic for breast cancer patients.

ABSTRACT

BACKGROUND AND PROPOSE: Cisplatin is a cytotoxic drug that triggers several toxicities. However, nephrotoxicity and ototoxicity remain major clinical limitations. The aim of our study was to evaluate the incidence of chemotherapy toxicity induced by cisplatin and to analyze the influence of risk factors in the Tunisian population. METHODS: We performed a prospective descriptive study in a period of four months. Patients were eligible if they had pathologically confirmed malignancies and treated with cisplatin-regimen chemotherapy. Nephrotoxicity and digestive toxicity were graded according to the World Health Organization toxicity scale and ototoxicity was scored clinically according to the Common Terminology Criteria for Adverse Events (CTCAE). Multivariate logistic regression analysis was performed to evaluate the influence of clinical variables on cisplatin-induced toxicity. RESULTS: A total of 150 patients were included. Forty-four percent of patients developed cisplatin-regimen toxicity: 15% developed cisplatin-induced nephrotoxicity, 9% cisplatin-induced ototoxicity and 27% digestive toxicity. In the multivariate analysis, age >65 years (OR= 6.129, p = 0.010), metastatic cancer (OR = 0.171, p = 0.007) and cumulative dose (OR= 1.004 mg/m2; p = 0.042) were strong predisposing factors for CDDP-induced nephrotoxicity. The cumulative dose was an independent prognostic indicator for digestive toxicity (OR = 0.997, p = 0.002). CONCLUSION: In our study, age >65 years and metastatic cancer were risk factors for cisplatin-induced nephrotoxicities. We also found the correlation between cumulative dose and nephrotoxicity or digestive toxicity.

ABSTRACT

The macroscopic behaviour of rubber-modified polymethyl methacrylate (PMMA) was investigated by taking into account the microdeformation mechanisms of rubber cavitation. The dependence of the macroscopic stress-strain behaviour of matrix deformation on the cavitation of rubber particles was discussed. A phenomenological elastic-viscoplastic model was used to model the behaviour of the matrix material, while the rubber particles were modelled with the hyperelasticity theory. A two-phase composite material with a periodic arrangement of reinforcing particles of a circular unit cell section was considered. Finite-element analysis was used to determine the local stresses and strains in the two-phase composite. In order to describe the cavitation of the rubber particles, a criterion of void nucleation is implemented in the finite-element (FE) code. A comparison of the numerically predicted response with experimental result indicates that the numerical homogenisation analysis gives satisfactory prediction results.
