All collected data were verified and analyzed using the Statistical Package for Social Sciences (SPSS). <strong>Results: </strong>Our findings revealed that 64.1% of the respondents had poor knowledge regarding plastics and phthalates with gender being a significant factor (p=0.0003). The usage rate of plastic material was found to be remarkably high with 38.2% keeping the purchased cheese either in its original plastic wrapping or placed inside plastic boxes. Moreover, 53.6% never viewed the safe plastic number before purchasing the food products. However Interestingly enough, the type of plastics did not influence participant’s decision-making process when it came down to purchasing or consuming cheese (45.1% &amp; 46.2%, respectively). Respondents who had poor practice represented up to 85 %, while those with poor knowledge and practice constituted 65.1%. However, no significant link between these two factors could be established.<strong> Conclusions: </strong>Poor awareness levels concerning phthalates along with imprudent usage rates for plastics were observed among adults living within Jeddah city's boundaries; thus, appropriate interventions aimed at raising awareness need implementation so as minimize exposure risks associated with this issue.</p> <p><strong>Keywords: </strong>Phthalate, Plastic use, Cheese, Knowledge, Practice, Saudi Arabia.</p> Rowida Allily Haneen H.

It is characterized by an increase in the size of the prostate, which can lead to urinary issues. In the past, the treatment of BPH was limited to surgery. However, the introduction of drugs such as Permixon, based on saw palmetto extract, has revolutionized the management of this disease. This natural plant extract is effective in relieving the symptoms of BPH and can also slow the progression of the disease. The Algerian population consumes several plants for this purpose, such as nettle, galangal, pumpkin seeds, and doum palm. The doum palm (<em>Chamaerops humilis</em>) is a bushy plant with fan leaves that is widely distributed in the Mediterranean region. The terminal bud of this species is edible, however the doum palm has been appreciated by several societies throughout time for its multiple traditional uses and is primarily exploited for its fibers. In addition, this plant has aroused growing interest for its properties, especially in the treatment of benign prostatic hyperplasia. <strong>Aims: </strong>This study aimed to evaluate the in vitro anti-inflammatory activity of the aqueous extract of the doum palm by the protein denaturation method comparing it to Permixon extracts and corticosteroids in order to valorize this species and confirm its traditional use. <strong>Material and Methods: </strong>The fruits of<em> Chamaerops humilis</em> L. were dried, powdered, and extracted with aqueous water then screened by various chemical tests. The anti-inflammatory activity was estimated after dilution of each extract using the human serum albumin. <strong>Results: </strong>When evaluating the anti-inflammatory effect, we observed that the fruit extract exhibited significantly higher activity, with an IC<sub>50</sub> of 446,02 mg/mL, too close to that of Permixon (IC<sub>50</sub>= 423.17 μg/mL) and exceeding that of corticosteroids (IC<sub>50</sub>= 602,21 mg/mL). All three extracts clearly demonstrated their ability to reduce inflammation. <strong>Conclusion: </strong>The aqueous extract was found to be an effective anti-inflammatory agent. These results offer promising novel perspectives in the treatment of inflammation-related diseases, especially benign prostatic hyperplasia.</p> <p><strong>Keywords: </strong>anti-inflammatory activity, benign prostatic hyperplasia, doum palm, Permixon, secondary active metabolites.</p> Nazim Bellifa Ismail Abedlhak Benhaddou Abedallah Berber Adil Selka Houari Toumi Copyright (c) 2024 Nazim Bellifa, Ismail Abedlhak Benhaddou, Abedallah Berber, Adil Selka, Houari Toumi https://creativecommons.org/licenses/by/4.0 2024-02-26 2024-02-26 8 17 44 51 10.51745/najfnr.8.17.44-51 Prognostic performance of serum protein markers in assessing mortali-ty risk for North African pediatric population hospitalized with com-plicated severe acute malnutrition https://najfnr.com/home/article/view/399 <p><strong>Background: </strong>Complicated severe acute malnutrition (SAM) continues to kill numerous pediatric populations at the global level. Yet, significant progress has been achieved in the clinical management and treatment of this lethal condition in the pediatric population. <strong>Aims: </strong>To determine the prognostic performance of selected serum protein markers in predicting high-risk mortality in a pediatric population with complicated SAM. <strong>Subjects and Methods: </strong>This non-interventional cohort prognostic accuracy study included 59 pediatric patients (aged 6 – 60 months) with complicated SAM admitted to Moulay Ali Cherif Regional Hospital, Errachidia, Morocco, during the period from 01.02.2021 to 02.11.2022. Only the SAM pediatric population with medical complications were included in the study. SAM was defined as weight-for-height or weight-for-length z-score &lt; -3 standard deviations, bilateral edema of nutritional origin, or mid-upper arm circumference &lt; 11.5 cm. The enrolled pediatric population received standard inpatient care as per World Health Organization protocols for nutritional rehabilitation of SAM. The pediatric population was divided into two groups, deceased (n=10) and survivors (n=49), based on their outcomes during their hospital stay. Blood samples upon admission were obtained to assess levels of transthyretin, transferrin, albumin, retinol-binding protein, fibronectin, and C-reactive protein. Diagnostic accuracy was assessed using the area under the curve (AUC), the sensitivity, specificity, positive predictive value, and negative predictive value. <strong>Results: </strong>At a threshold of (≤ 0.13 g/L), transthyretin displayed the best performance of all nutritional markers, with an AUC of 0.71, good sensitivity (80.4%), and specificity (73%). While transferrin, albumin, retinol-binding protein, fibronectin, and C-reactive protein presented good to excellent sensitivity and negative predictive value, their performance was rated “fail” to “poor” (0.5 ≤ AUC &lt; 0.7) with a “poor” positive predictive value. <strong>Conclusion: </strong>Low levels of transthyretin (≤ 0.13 g/L) demonstrated a prognostic advantage compared to other biomarkers such as transferrin, albumin, retinol-binding protein, fibronectin and C-reactive protein suggesting transthyretin's potential as a prognostic marker for predicting pediatric population with complicated SAM at high mortality risk.</p> <p><strong>Key-words: </strong>biochemical markers; death; predictive accuracy; undernutrition.</p> Hassan Barouaca Copyright (c) 2024 Hassan Barouaca https://creativecommons.org/licenses/by/4.0 2024-02-19 2024-02-19 8 17 11 20 10.51745/najfnr.8.17.11-20 Investigating bacterial gastroenteritis prevalence in the population of Tizi-Ouzou city under the context of social distancing and barrier measures https://najfnr.com/home/article/view/385 <p><strong>Background: </strong>Epidemics of gastroenteritis are responsible for more than one million consultations in general medicine each year. <strong>Aims: </strong>This study aimed to isolate and identify the main bacteria at the origin of gastroenteritis, and to follow the distribution of these pathogenic bacteria within the population to predict hygiene conditions in the city of Tizi-ouzou. <strong>Material and Methods: </strong>Our study was conducted during the summer of 2022 on 106 liquid and semi-liquid stool samples. <strong>Results: </strong>The results of direct examination and fecal culture revealed the absence of pathogenic organisms, which constitutes a promising result. <strong>Conclusions: </strong>The findings correlate with a rise in COVID-19 cases during the survey period. Hence, the probable reason for the absence of pathogenic germs is the efficacy of social distancing and barrier measures, specifically in curbing the transmission of fecal-oral contaminations.</p> <p><strong>Keywords: </strong>Bacterial gastroenteritis, stool culture, diarrhea, COVID pandemic.</p> Khalef Lefsih Yasmine Cherifi Nesrine Cherfi Dyhia Lakrouz Copyright (c) 2023 Khalef Lefsih, Yasmine Cherifi, Nesrine Cherfi, Dyhia Lakrouz https://creativecommons.org/licenses/by/4.0 2023-12-15 2023-12-15 8 17 146 155 10.51745/najfnr.7.16.146-155 Impact of deep-fat frying cycles on the physicochemical characteristics of two edible vegetable oils marketed in Algeria https://najfnr.com/home/article/view/383 <p><strong>Background: </strong>Vegetable oils containing polyunsaturated fatty acids are prone to oxidation when exposed to high-temperature frying processes. <strong>Aims: </strong>This study aims to follow the changes that occur in frying oil when used to fry potatoes. <strong>Material and Methods: </strong>The impact of the ratio of potatoes (g) to oil (g) as well as the number of frying cycles on the quality of two commonly marketed oils in Algeria: 100% soybean oil (oil A) and a blend of 60% soybean, 20% sunflower, and 20% corn oil (oil B) was assessed. The quality of these oils throughout repeated frying cycles was monitored by analyzing pH, density, color, moisture, acidity, peroxide value, saponification value, and acid index. <strong>Results: </strong>The results of the present study revealed that both oils experienced deterioration as the frying cycles were repeated, with more significant degradation observed with the 1/5 ratio of fries to oil compared to the 1/8 ratio. Remarkably, the 100% soybean oil deteriorated more rapidly than the oil blend. <strong>Conclusion: </strong>Based on the observed changes in physicochemical parameters and chemical indices, the use of frying oils beyond the third cycle significantly compromises their quality and safety. This not only impacts the consumer’s health but also the organoleptic properties of fried foods. Therefore, it is highly recommended to refrain from exceeding this limit to ensure optimal frying practices and protect consumer health.</p> <p><strong>Keywords: </strong>Vegetable oils, deep-fat frying, ratio of fries/volume of oil, physical quality, chemical indices.</p> Farida Benmeziane, Khawla Araba Amina Belahcene Copyright (c) 2024 Farida Benmeziane,, Khawla Araba, Amina Belahcene https://creativecommons.org/licenses/by/4.0 2024-02-12 2024-02-12 8 17 21 31 10.51745/najfnr.8.17.21-31
