Turnaround Time of the Hematology Results of Cancer Patients During the COVID-19 Pandemic: An Opportunity to Initiate a Quality Improvement Process.

INTRODUCTION: Turnaround time (TAT) is a crucial clinical parameter that reflects the performance of a laboratory especially in the context of oncology and the COVID-19 pandemic. Based on the Lean Six Sigma methodology, we performed a retrospective analysis of the TAT of the complete blood count (CBC) of cancer patients with the aim of reducing this delay in the future. MATERIALS AND METHODS: Over one month of the COVID-19 pandemic, a retrospective evaluative audit was carried out on the TAT of the CBC in an oncology department. The root causes of failures of the overall analysis process were detected. The initiation of an improvement approach was implemented through the creation of an improvement flowchart and a new request form. The hospital information system (HIS) data were exported to Microsoft Excel® (Microsoft Corporation, Redmond, Washington, United States). Using the collected data, the mean, standard deviation, median, and interquartile range were calculated using IBM SPSS Statistics for Windows, Version 23, (Released 2015; IBM Corp., Armonk, New York, United States). All time intervals were expressed in minutes. RESULTS: Among 263 intra-laboratory TATs analyzed, the median intra-lab TAT was 56 minutes (interquartile range (IQR): 36-80 minutes). A total of 82% of the analyses were performed in less than 90 minutes with a predominance of the interval 30-59 at 42.9%. The main causes of failures were essentially the lack of time stamping of the samples as well as the lack of real-time communication between the biologists and the clinicians. The proposed improvement model is currently being approved by all practitioners whose main items are as follows: At the clinical department level, distinguish the request forms but also the labels of the samples of the oncology hospital by a particular color, indication of clinical signs and sampling time on the request forms and on the HIS. At the laboratory level, create a specific chain for oncology department samples, alarm notification on the HIS, and rapid telecommunication of results for vital situations. CONCLUSION: The intra-lab TAT of our study is biologically acceptable. Because our work is limited by the phases outside the control of the laboratory, it should lead to a continuous improvement project.

This research article provides a concise synthesis of current knowledge in the field of galenic pharmacy focused on targeted drug delivery in oncology. This research article synthesizes current knowledge in galenic pharmacy, focusing on targeted drug delivery in oncology and reviewing recent advancements in nanopharmaceuticals for cancer treatment. DATA SOURCE: The data for this review are derived from a comprehensive analysis of the most cited scientific literature (Pubmed). Recent studies, clinical trials, and technological breakthroughs related to nanopharmaceuticals have been rigorously examined. This diverse source ensures a comprehensive representation of the latest developments in the field. SUMMARY OF DATA: The results highlight the emergence of nanopharmaceuticals as a promising approach to cancer treatment. The most common in oncology remain liposomes, nanopolymers, and nanocrystals. From a galenic point of view, these three forms offer a wide range of improvements compared to conventional forms such as improvement in solubility as well as stability. The same observation is in the clinic where treatment response rates are significantly improved. The most advantageous form will depend on the specific characteristics of each patient and each type of cancer. The precise design of nanocarriers allows for targeted drug delivery, enhancing therapeutic efficacy while reducing side effects. Concrete examples of clinical applications are presented, illustrating the practical potential of these advancements. CONCLUSION: In conclusion, this review provides a holistic overview of recent developments in galenic pharmacy for targeted drug delivery in oncology. The stability of nanocarriers is a crucial challenge because it conditions the effectiveness and safety of the drugs transported. Environmental and biological variations encountered in the body can compromise this stability, jeopardizing the therapeutic effectiveness and safety of treatments. Likewise, personalized approaches are essential to address interindividual variations in treatment response, as well as patients' pharmacogenomic profiles, in order to optimize therapeutic effectiveness and minimize adverse effects.

Manual versus automated chemotherapy preparation: A retrospective pharmaco-economic analysis.

INTRODUCTION: The National Oncology Institute of Morocco's (NIO) shift to an automated cytotoxic drug preparation system (PHARMODUCT®) has prompted an evaluation of its economic and clinical impacts compared to traditional manual methods. METHODS: A retrospective cost-benefit analysis over six months, extrapolated to annual projections, assessed initial investments, labour, equipment, drugs and consumables. Four commonly used chemotherapy drugs were analyzed, with a focus on the cost implications of drug waste in manual preparation versus the efficiency of vial-sharing in automated methods. RESULTS: The automated system incurred a higher initial cost $2,934,098.74, but reduced annual drug consumption costs by 19.74% and drug-related expenses by $41,228.27. It also decreased personnel costs by $48,073.35. Despite the upfront investment, the system is projected to break even within two years, with no medication waste due to its vial-sharing capability. CONCLUSION: The initial higher investment in pharmaceutical automation promises considerable long-term savings and efficiency gains. Despite the study's limited scope and duration, the findings endorse the adoption of automated systems in oncology pharmacy settings for sustainable financial management and improved clinical outcomes.

Optimizing chemotherapy medication leftover management circuit in a centralized chemotherapy preparation unit: A comprehensive FMECA risk analysis and continuous improvement approach.

OBJECTIVE: Chemotherapy medications are usually having high costs, and new targeted drugs can be especially expensive, representing a challenge on healthcare, particularly in low- and middle-income countries. As cytotoxic leftover management is crucial for reducing medication wastage, the aim of this study is to evaluate and optimize leftover management circuit in NIO'S Pharmacy Centralized Chemotherapy Preparation Unit (CCPU) through a Failure Mode, Effects and Criticality Analysis (FMECA), and propose continuous improvement element to enhance the security of the process. METHOD: The FMECA were conducted in NIO's CCPU from March to May 2023, then continuous improvement plan was established to enhance the security of the process. The failure modes, their causes, impact, and criticality were assessed through criticality index calculation (CI = severity × frequency × detectability), and the risk concerned safety and effectiveness disruptions in chemotherapy preparation circuit using cytotoxic leftover. RESULTS: Leftover management circuits were described in flowchart form, where 18 failure modes were detected in four different steps of the process from chemotherapy preparation to disposal. Failure with highest critical index were detected in the case of equipment malfunction, improper storage temperature, and humidity. Continuous improvement recommendations were proposed in a table form. CONCLUSION: FMECA analysis applied to NIO's chemotherapy leftover management process allowed us to evaluate, secure, and optimize the circuit, and to propose several actions to implement in a perspective of continuous improvement.

Retrospective and FMECA analysis of failures in closed-system devices.

INTRODUCTION: Cytotoxic drugs can be hazardous to healthcare workers involved in their preparation and/or administration. Exposure occurs during routine handling of drug vials and ampoules, preparation, administration and disposal of cytotoxic waste. The use of closed-system devices provides protection against exposure to cytotoxics, but these devices are the subject of numerous incidents. Given the nature of the drugs they contain, these incidents can be dangerous for the personnel handling them. OBJECTIVE: The aim of our study is to analyze material vigilance data relating to problems frequently encountered with the various consumables of the closed system and to assess the risk of exposure of personnel to cytotoxic drugs when using these using the Failure Mode and Criticality Analysis (FMECA) method. MATERIALS AND METHODS: Our study was conducted at the pharmacy of the National Institute of Oncology, the closed system drug transfer device (CSDT) used is a ChemoClave-ICU®, This device is mechanical and needleless For the materiovigilance study we carried out a retrospective study over the period from 2019 to 2022, analyzing materiovigilance data collected by National Institute of Oncology's materiovigilance and pharmacovigilance cell. Our team, trained in the FMECA method, conducted the study over a three-month period, between September and November 2022. The method was used to assess the risks incurred by staff when using the CSDT device to prepare cytotoxic drugs. CONCLUSION: Our study revealed that the most frequent incident was linked to a manufacturing defect in the device in question. According to the FMECA analysis, this incident represents a major risk, as its occurrence hampers the cytotoxic preparation process. CSDT have the advantage of being easy to use and acceptable to staff, but standards need to be developed and validated to assess the performance of these devices.

Evaluating cost savings in cytotoxic leftover management: A prospective study of vial sharing and dose rounding techniques in the Moroccan National Institute of Oncology.

OBJECTIVE: Most intravenous anticancer drugs are administered in a dose per unit area or body weight, if not promptly administered to another patient cytotoxic leftover would be destroyed. To contain wastage, low-cost measures are highly desirable to contain and reduce expenditures without impairing the quality of care. The objective of the study is to evaluate the cost saved through the use of the two cytotoxic waste management techniques implemented in National Institute of Oncology's centralized chemotherapy preparation unit, vial sharing and dose rounding. METHOD: A 6-month prospective single centre study from 1 February to 1 August 2023 at the National Institute of Oncology of Rabat in Morocco. The number of prepared preparations and amount of drug saved by both vial sharing and dose rounding was collected using the centralized chemotherapy preparation unit's 'leftover tracking file', the corresponding cost saved were calculated and then compared for each technique and with 2018 results. RESULTS: In total, 18,218 preparations were considered in the 6-month study. With the vial sharing technique 636,524.5 mg were saved corresponding to 246,031.4 (USD) saved cost, against 212,838.4 mg by dose rounding corresponding to 75,598.5 (USD) saved cost. This saving corresponded to a total of 321,629.4 (USD). Compared to the 2018 results leftovers costs saved by vial sharing corresponded to 289,972.05 (USD) by vial sharing technique for 1-year extrapolated period, and this study shows a saved cost of 321,629.9 (USD) by both vial sharing and dose rounding techniques. CONCLUSION: Dose rounding technique combined with vial sharing allowed National Institute of Oncology's centralized chemotherapy preparation unit to limit expensive cytotoxic cost wastage, highlighting these technique benefits.

Assessment of patients' knowledge of their treatment with capecitabine at the National Institute of Oncology in Rabat.

INTRODUCTION: Capecitabine is a molecule of choice in the therapeutic arsenal of anticancer drugs used in Morocco for the treatment of breast cancer and colorectal cancer. Its frequent use imposes a follow-up and a post-prescription monitoring of the treatment modalities as well as the adverse events that may occur following its administration. OBJECTIVE: The objective of this study is to evaluate the level of knowledge of patients in the day hospital of an oncology facility about their treatment with capecitabine. MATERIALS AND METHODS: This is a prospective study conducted over a period of 2 months (January-February 2022) at the day hospital in the National Institute of Oncology in Rabat, and it was conducted using a questionnaire in order to evaluate patients' knowledge about their treatment with capecitabine. RESULTS: This study involved 95 patients, 76% claimed to have ever received pharmaceutical advice on capecitabine treatment. The main indications were colorectal and breast cancer. Ninety seven percent knew the indication for capecitabine and the action of the molecule on the relevant tumor. Eighty three percent receiving capecitabine therapy reported the occurrence of side effects and hand-foot syndrome was the most reported in 31.2% of the total listed side effects. DISCUSSION: Capecitabine is an oral treatment of choice for colorectal and breast cancer in Morocco. Therapeutic education happens to be an effective tool in order to guarantee the best effectiveness and manage the possible side effects that can occur during the treatment.

Risk assessment of personnel exposure in a central cytotoxic preparation unit using the FMECA method.

INTRODUCTION: Personnel involved in the preparation of cytotoxics are exposed to them and the resulting risks. To protect themselves, many means of protection are currently implemented. Nevertheless, the exposure of these manipulators remains a possibility to be considered. MATERIALS AND METHODS: The study was conducted during the period (October-November 2022) in the pharmacy of the National Institute of Oncology (INO), a hospital structure specializing in cancer care. The Failure Mode, Effects and Criticality Analysis method was used to assess the risks of exposure of personnel in a central cytotoxic preparation unit and then calculate the criticality index (CI = severity × frequency × detectability). The risks were classified into toxic, traumatic, chemical, and environmental risks. We have cited 12 failure modes of which nine are minor and three are major. The three major modes cited are essentially related to the particulate environment, direct contact and daily passive inhalation of handling. CONCLUSION: Our study shows that in our institution, the analysis of the risk of exposure of personnel to cytotoxics remains important, hence the interest of automaton in charge of preparations and which will gradually take charge of all the preparations. The existing procedures and the pharmacotechnical equipment used also contribute to protection and risk reduction.

Retrospective analysis of failures of ambulatory elastomeric pumps containing 5-FU in a hospital pharmacy unit.

INTRODUCTION: Ambulatory chemotherapy is an important and major advance in clinical oncology practice since it allows the administration of chemotherapy in the comfort of the patient's home without the assistance of a health professional by means of an elastomeric pump. However, these pumps are not without risks and can be the cause of incidents due to technical failures. Our objective is to study the technical failures of elastomeric pumps in the Cytotoxic Preparation Unit and in the patient's home, to evaluate the possible impact of these failures on the patient and on the staff and to propose measures to reduce them. MATERIALS AND METHODS: This is a retrospective study conducted at the pharmacy of the National Institute of Oncology in Rabat. It gathered all the specific reports on elastomeric pumps issued during the period (January 2017-May 2021) by the cytotoxic preparation unit to the materiovigilance cell via a notification form. RESULTS: 205 cases of elastomeric pump materialovigilance were identified during the study period. The main technical failures were: chemotherapy product leakage (44%), flow rate anomalies (30%) and injection difficulties (20%). Following these incidents, certain actions were undertaken such as alerts sent to the supplier and letters sent to the competent health authorities. CONCLUSION: Despite the failures that may have occurred, elastomeric pumps have revolutionized home chemotherapy delivery. They are considered reliable, consistent, easy to use and handle, and are well accepted in the population.

CASE REPORT: A 57-year-old woman, followed for invasive ductal carcinoma of the left breast under tamoxifen for 7 years, presenting joint pain with deformities in her fingers. MANAGEMENT & OUTCOME: Following the appearance of the adverse effect, tamoxifen was stopped. A series of biologic and radiologic analysis were performed in order to explain the appearance of this event. A substitution treatment was discussed and a rheumatologist's opinion was requested. DISCUSSION: Tamoxifen appears to be associated with the development of inflammatory osteoarthritis resembling rheumatoid arthritis. Possible mechanisms of such an effect are discussed.

Contribution of an anticancer drug compounding robot in reducing the risks of manual preparation in a hospital pharmacy unit specialized in oncology.

INTRODUCTION: In the last few years, pharmaceutical technology has evolved. In the field of oncology pharmacy, robots for the preparation of anti-cancer drugs have appeared to progressively replace manual preparation. The objective of this study is to evaluate the contribution of the robot in reducing the risk of manual preparation. METHODS: The study was conducted at the pharmacy of the National Institute of Oncology in Rabat (May-August 2021). The method used to compare the two types of preparation is the method of analysis of failure modes, their effects and their criticality (FMECA). It will calculate the criticality index (CI = severity × frequency × detectability). The risks have been categorized into human, technical, and environmental risks. RESULTS: The anticancer drugs reconstitution step was the most critical in manual preparation (CI = 126.7) and robotic preparation (CI = 40.7). The robot has made it possible to reduce several CIs of manual preparation including: musculoskeletal disorders of pharmacy operators -93 (89%), error in cancer drug and diluent selection -72 (60%), as well as lack of traceability -145 (97%). CONCLUSION: The preparation robot has made it possible to reduce many of the risks of manual preparation, and constitutes an important advance in the field of oncology pharmacy.

Economic impact of implementation of an automated drug supplying and management system in a Central Chemotherapy Preparation Unit in a Moroccan hospital.

OBJECTIVE: Automated Drug Supplying and management System (ADS) are effective devices that secure drug's circuit and reduce hospital's expenses. The purposes of this study are to estimate the earnings made from ADS through a cost-benefit medical economic study, to highlight its impact on Central Chemotherapy Preparation Unit's (CCPU) global organization, its ergonomy and staff's satisfaction. METHOD: Measurement of cytotoxic drug's consumption, expiration losses, pharmacy staff's working time, drugs stock-out before and after the implementation of ADS on the one hand, and assess its ergonomy and acceptability by users on the other hand. RESULTS: After the implementation of ADS, cytotoxic drug's consumption decreased by 9 (%), expiration losses by 98.3 (%), and we could see a gain in working time among CCPU'S technicians of 1.32 (h/day) and pharmacist of 0.67 (h/day), in contrast to the stock manager who increased his working time by 0.95 (h/day). Stock-out have decreased by 41.1 (%). The cost-benefit analysis has shown a net benefit of 67,437 between the two six-month phases, which corresponds to an economy of 134,874 (USD) over one year. The ADS was generally appreciated by the CCPU and pharmaceutical staff and 93(%) don't want to return to the old system. CONCLUSION: ADS implementation within CCPU led to financial savings in the hospital, an optimization of expenses and better pharmaceutical management.

Impact of clinical pharmacy services in a hematology/oncology ward in Morocco.

BACKGROUND: Clinical pharmacists are contributing to safe medication use by providing comprehensive management to patients and medical staff. The aim of this study is to document and evaluate the role of clinical pharmacy services in oncology department. PATIENTS AND METHODS: A prospective, descriptive, observational study was carried out from July 2018 through June 2019 at the Department of Medical Oncology at the National Institute of Oncology, Morocco. Medication reviews concerning hospitalized adult cancer patients were performed every day by the clinical pharmacist assigned to the department. RESULTS: A total of 3542 prescriptions of 526 adult cancer patients were analyzed. The pharmacist identified 450 drug-related problems (12.7% of the prescriptions) primarily related to the analgesics (31.5%). Medication problems included mostly untreated indications (31.3%), overdosing (17.1%), drug-drug interactions (12.4%), underdosing (11.1%), administration omissions (6.7%), drug not indicated (6.0%), and contraindication (5.3%). Interventions (n = 450) led to drug additions (30.7%), drug dosing adjustments (27.1%), treatment discontinuations (20.0%), recall of the treatment (6.2%), replacement of a drug with another one (5.1%), administration optimization (4.0%), therapeutic drug monitoring (3.1%), alternate routes of administration (2.5%), and extension of treatment duration (1.3%). Most (98%) of the interventions were accepted and implemented by the medical staff-172 (38.2%) having a significant clinical impact on the patient, 88 (19.6%) as having a very significant clinical impact, and 71(15.8%) as having a potential vital impact. CONCLUSION: This work highlights the positive clinical relevance of pharmacists' interventions in oncology and the importance of medicopharmaceutical collaboration to prevent medication error.

Risk reduction in a cancer chemotherapy production unit: Contribution of an automated drug dispensing system.

OBJECTIVE: The purpose of our study was to evaluate the contribution of an automated drug dispensing system in securing cancer chemotherapy production process at the pharmacy of the National Institute of Oncology in Rabat. METHODS: The failure modes and effects analysis method was applied to the chemotherapy production process in two phases: Phase 1, using an open shelf for storage then phase 2, using an automated drug dispensing system. The failure modes were defined and their criticality indexes was calculated on the basis of the likelihood of occurrence, the potential severity for the patients and/or the impact on the process and the detection probability. The criticality indexes of the two phases were prioritized and compared. RESULTS: We identified 35 failure modes for phase 1 and 37 for phase 2. The sum of criticality indexes was 5957 and 4586, respectively, for phase 1 and phase 2, corresponding to a criticality reduction of -23%. The greatest improvements concerned that the needed drug is missing during the picking, storage of potential expired drugs, and double compounding. CONCLUSION: Our study highlighted the contribution of automated drug dispensing system in risk minimization. The use of automated drug dispensing system is a part of security improvement in chemotherapy production unit.

Frequency and types of EGFR mutations in Moroccan patients with non-small cell lung cancer.

BACKGROUND: Mutations in the epidermal growth factor receptor (EGFR) gene are commonly observed in non-small cell lung cancer (NSCLC), particularly in adenocarcinoma histology. The frequency of EGFR mutations is ethnicity-dependent, with a higher proportion reported in Asian populations than Caucasian populations. There is a lack of data on these mutations in north Africa. METHODS: Tumor specimens from Moroccan patients with NSCLC were collected from five pathology laboratories between November 2010 and December 2017 to determine frequency and types of EGFR mutations. Tumors were tested in a reference center for EGFR by polymerase chain reaction and sequencing of exons 18, 19, 20, and 21. RESULTS: A total of 334 patients were enrolled: 242 (72.5%) males and 92 females (27.5%). A total of 56.9% had a history of smoking. EGFR testing of the 334 lung adenocarcinoma samples demonstrated a wild-type EGFR in 261 (78.1%) and mutated EGFR in 73 (21.9%). Mutations were mainly detected in the exon 19 deletion (65.8%), followed by exon 21 L858 (17.8%) and other exon 21 codon mutations (5.5%) and exon 18 (6.8%), whereas primary mutations of exon 20 were less frequent (4.1%). In patients with advanced NSCLC, the detection of EGFR mutation was independently associated with sex (41.3% female vs 14.5% male; p < 0.001) and smoking status (34.8% nonsmokers vs 12.9% active smokers; p < 0.001). The mean age was significantly different between the two groups (p = 0.041). CONCLUSION: Our findings confirm the genetic heterogeneity of NSCLC worldwide, reporting frequency of EGFR mutations in Moroccan patients with NSCLC between those of Asian and Caucasian populations.

Centralization impact and cost-saving study in a Moroccan hospital's centralized unit of chemotherapy preparation.

PURPOSE: The purpose of this study was to assess the cost saved and the amount of drug wasted when compounding anticancer drugs in the centralized unit for chemotherapy preparation. A secondary objective was to estimate the centralization impact of activities related to the preparation of chemotherapies. METHODS: This was a two-month, single-centre, prospective study conducted at the National Oncology Institute in Rabat. The cost saved and the amount of drug wasted were calculated using a standardized data collection sheet (the prescribed dose, the amount of drug deployed, the amount remaining after compounding, the amount of drug saved and the drug wastage). The centralization impact was calculated using the amount of drug wasted in the centralized unit for chemotherapy preparation and a theoretical amount of drug wasted without centralization of preparation. RESULTS: During the study period, the total amount of drug saved was 249,959.5 mg (7.2% of drug used), which represented 96,657 USD. The amount of drug wasted was 89,290.5 mg or 42275.5 USD. The drug waste per dilution and per drug was 6.4 mg [1.6-16.1]. While the potential savings over one year (580,000 USD) reached 13.9% of the cytostatic drugs budget for 2018, the potential drug waste cost reached 6.1%. The centralization impact is estimated at an average of 79.5% ± 13.7% waste reduction. CONCLUSION: The outcome of our study showed that the grouping of prescriptions in centralized unit for chemotherapy preparation could result in significant savings on the amount of drugs deployed. The centralization of cytostatic preparations is of economic interest.

Interactions between injectable anticancer drugs and polyvinyl chloride bags: Evaluation of the adsorption phenomenon after reconstitution.

INTRODUCTION: During the reconstitution of a drug and during its storage, there are risks of interactions between the drug and the bag used for the preparation. Polyvinyl chloride is a material used in the manufacture of a large part of chemotherapy infusion bags. It is subject to many interactions like sorption of drugs and release of phthalate additives. MATERIAL AND METHODS: Seven anticancer drugs used in pediatric oncology were involved in our study. After reconstitution of the anticancer agents in polyvinyl chloride bags, the adsorption phenomenon between the container and the contents is evaluated by infrared spectroscopy by analyzing the inner surface of the polyvinyl chloride. Subsequently, for the anticancer agents which exhibited an adsorption-container-content, the analysis was carried out by ultraviolet-visible spectrophotometry in order to examine the kinetics of the concentration of reconstituted anticancer drugs. RESULTS: All the polyvinyl chloride bags gave a spectrum identical to the spectrum of the reference bag, except the bags used to reconstitute etoposide whose spectra showed 12 additional peaks. With the absorbances measured by ultraviolet-visible spectrophotometry at different times, the analysis of variance statistical analysis shows that there is a significant difference in absorbances between t0 and all the other measurement times. CONCLUSION: This study testifies to the existence of a container-content interaction between etoposide and polyvinyl chloride. Thus, reconstitution of etoposide for intravenous infusion into a polyvinyl chloride bag should be used immediately. For etoposide preparations intended for storage beyond 24 h, it is recommended to use a container other than the polyvinyl chloride bag.

Skin hydration in postmenopausal women: argan oil benefit with oral and/or topical use.

THE AIM OF THIS STUDY: The aim of this study was to evaluate the effect of daily consumption and/or application of argan oil on skin hydration in postmenopausal women. MATERIAL AND METHODS: Sixty postmenopausal women consumed butter during the stabilization period and were randomly divided into two groups for the intervention period: the treatment group absorbed alimentary argan oil (n = 30) and the control group olive oil (n = 30). Both groups applied cosmetic argan oil in the left volar forearm during a sixty days' period. Evaluation of skin hydration, i.e. transepidermal water loss (TEWL) and water content of the epidermis (WCE) on both volar forearms of the two groups, were performed during three visits at D0, D30 and after sixty days (D60) of oils treatment. RESULTS: The consumption of argan oil has led to a significant decrease in TEWL (p = 0.023) and a significant increase in WCE (p = 0.001). The application of argan oil has led to a significant decrease in TEWL (p = 0.01) and a significant increase in WCE (p < 0.001). CONCLUSIONS: Our findings suggest that the daily consumption and application of argan oil have improved the skin hydration by restoring the barrier function and maintaining the water-holding capacity.
