Effectiveness of Fortified Garlic Extract Oral Capsules as Adjuvant Therapy in Hospitalized Patients with Coronavirus Disease 2019: A Triple-Blind Randomized Controlled Clinical Trial.

Background: Herbal medicines have been extensively used to treat coronavirus disease 2019 (COVID-19). Garlic, known to exert antiviral and anti-inflammatory effects, can be coadministered with standard treatments to combat COVID-19. Objectives: The aim of the study was to evaluate the efficacy and safety profile of Gallecina oral capsules (Samisaz Pharmaceutical Company, Mashhad, Iran), a fortified garlic extract, as adjunctive therapy to improve the clinical status and symptoms in noncritically ill patients hospitalized for COVID-19. Methods: This triple-blind randomized, placebo-controlled clinical trial was conducted on noncritically ill patients with COVID-19 hospitalized in the nonintensive care wards of Imam Hassan Hospital. Patients received remdesivir plus 90 mg Gallecina capsule or a placebo every 8 hours for 5 days or until discharge. The clinical status, respiratory symptoms, and laboratory parameters were recorded during the study period. Results: Patients were enrolled between April 24 and July 18, 2021. Data from 72 patients in the Gallecina group and 69 patients in the placebo group were analyzed. Oxygen saturation, C-reactive protein levels, and the distribution of respiratory distress and cough were similar between groups on the day of discharge. Although body temperature was significantly lower in the Gallecina group than that in the placebo group on the day of discharge (P = 0.04), it was within the normal range for both groups. The proportion of patients requiring supplemental oxygen for at least 1 day during the study was significantly reduced in the Gallecina group on days 3 and 4 and the day of discharge (P < 0.05). Gastrointestinal complaints were more prevalent in the Gallecina group than in the placebo group but the difference was not statistically significant (P = 0.12). Conclusions: There was no significant effect on the primary outcome of clinical status on study day 6. Although the proportion of Gallecina-treated patients who needed supplemental oxygen significantly decreased on days 3 and 4 and the day of discharge, there was no significant difference between the groups on other days. The possible beneficial effects on oxygen requirements in noncritically ill COVID-19 patients may warrant further investigation. (Curr Ther Res Clin Exp. 2023; 84:XXX-XXX).

Development of quality indicators to measure pre-hospital emergency medical services for road traffic injury.

BACKGROUND: Pre-Hospital Emergency Care (PEC) is a fundamental property of prevention of Road Traffic Injuries (RTIs). Thus, this sector requires a system for evaluation and performance improvement. This study aimed to develop quality indicators to measure PEC for RTIs. METHODS: Following the related literature review, 14 experts were interviewed through semi-structured interviews to identify Quality Measurement Indicators (QMIs). The extracted indicators were then categorized into three domains: structure, performance, and management. Finally, the identified QMIs were confirmed through two rounds of the Delphi technique. RESULTS: Using literature review 11 structural, 13 performance, and four managerial indicators (A total of 28 indicators) were identified. Also, four structural, four performance, and three managerial indicators (A total of 11indicators) were extracted from interviews with experts. Two indicators were excluded after two rounds of Delphi's technics. Finally, 14 structural, 16 performance and, seven managerial indicators (A total of 37indicators) were finalized. CONCLUSION: Due to the importance and high proportion of RTIs compared to other types of injuries, this study set out to design and evaluate the QMIs of PEC delivered for RTIs. The findings of this research contribute to measuring and planning aimed at improving the performance of PEC.

Single Free Flap for Large Defects in Head and Neck Reconstruction, Double Paddle Anterolateral Thigh Flap.

ABSTRACT: The purpose of the study is to evaluate the efficacy of double skin paddle anterolateral thigh flap (ALT) to reconstruction of through and through oral cavity defect due to cancer surgery.A prospective review was performed of patients referred to Firoozgar and Erfan hospitals with oral cavity defects with two or more oral cavity subunits and skin simultaneously involvement and immediate reconstruction using double-skin paddle ALT flap at the same time of tumor ablation from January 2019 to November 2020.A total number of 6 patients was evaluated. The mean area of skin paddle was 110.4 cm2 and 92.8 cm2 in distal and proximal paddle respectively. Except one patient was complicated and expired in hospital admission, the remaining 5 patients got fully oral intake and completely survived flaps with primarily closed donor site. Tumor recurrence was not found in the mean follow-up time of 12 months.The double skin paddle anterolateral thigh flap serves as an efficient reconstruction technique in complex and perforating oral cavity defects with the same functional outcome and the same flap related complications as conventional ALT flap.

Local tissue reaction and histopathological characteristics of three different bulking agents: a rabbit model.

PURPOSE: We assessed the efficacy and safety of a single injection of three bulking agents over the short- and long-term follow-ups in rabbits. Dermal and preputial matrices were compared with Deflux (DxHA) injection. MATERIAL AND METHODS: Twenty-four rabbits were divided into three groups. Group I (n=8) underwent the injection of a lyophilized dermal matrix (LDM) beneath the seromuscular layer of the bladder wall. Rabbits in group II (n=8) were injected with lyophilized preputial matrix (LPM). Rabbits of group III (n=8) were injected with DxHA as the control group. They were followed up for 1 and 6 months after the injection. Subcutaneous injection of all bulking agents was also performed in nude mice. Biopsies were stained with LCA (leukocyte common antibody), CD68, CD31, and CD34. Scanning electron microscopy (SEM) and MTT assay were also performed. RESULTS: Immunohistochemistry staining with CD68 and LCA revealed higher inflammation grade in LDM as compared with LPM and DxHA. Fibrosis grade was also higher in LDM both in short- and long-term follow-ups. However, no significant difference was detected in CD31 and CD34 staining between control and experimental groups. SEM analysis showed that the particle size of LPM was more similar to DxHA. MTT assay revealed that cell proliferation was similar in DxHA, LDM, and LPM. In-vivo assay in nude mice model showed more promising results in LPM as compared with LDM. CONCLUSION: The long-term results demonstrated that LPM was more similar to Deflux with the least local tissue reaction, inflammation, and fibrosis grade.

Developing a model for prevention of malnutrition among children under 5 years old.

BACKGROUND: Serious consequences leading to the increase of infectious diseases and mortality of children justifies the importance of interventions for eradication of malnutrition. Thus, this study aimed to provide a model for the prevention of malnutrition among children under 5 years old (CU5) in Iran. METHODS: This paper is part of a bigger study, conducted in 2017 using a mixed methods approach. A model for prevention of malnutrition in CU5 was proposed based on the earlier steps, with the cooperation and consultation of experts and specialists. In the final step, a Delphi method was used to determine the validity of the proposed model. RESULTS: The main dimensions of the prevention model of malnutrition for CU5 in Iran included four level: basic causes, interventions, outcomes and impact. The proposed interventions are presented based on twelve areas: structural, intersectoral, political, economic, sanitary, health-oriented, research, educational/cultural, evaluation related, production, infrastructures and legal. Based on these areas, 118 solutions were finally selected for the final model. This model is designed based on the current conditions in different regions of Iran, the factors related to child malnutrition, affective context on policy making, the content of previous policies, the process of policy making in Iran, and key stakeholders and actors in policy making. CONCLUSION: In order to prevent malnutrition, the causing factors should be identified and resolved. The adopted policies should be, more seriously, based on the presence of key stakeholders and actors. Most of the existing nutritional problems among children are because of inappropriate consumerism culture and habits in families and its transfer to children.

Challenges of managing diabetes in Iran: meta-synthesis of qualitative studies.

BACKGROUND: Although several diabetes management and control programmes are introduced in Iran, many patients do not achieve diabetes-related clinical goals as recommended. The aim of this study was to identify the qualitative evidence for the challenges regarding diabetes management. METHODS: A systematic review of qualitative studies following PRISMA guidelines was undertaken. Scopus, PubMed, Science Direct, and Web of Knowledge were searched as well as Persian databases including Magiran, Irandoc and SID from inception to August 2019. The included Studies were either in English- or Persian-language qualitative studies reporting the perspectives of patients, their relatives, or healthcare service providers. Content of the findings were analysed and organized according to Chronic Care Model framework. RESULTS: Twelve studies met the inclusion criteria. Six main themes were identified including holistic understanding of patients, leadership and governance difficulties, service delivery, workforce, financing, and information and research. CONCLUSION: Challenges regarding the management of diabetes in Iran is multifaceted. Reforming the health care system or developing complementary strategies is essential to improve suitable health care model for patients with chronic conditions such as diabetic patients.

Experts' perspectives on the application of public-private partnership policy in prevention of road traffic injuries.

PURPOSE: Successful application experiences on public-private partnership (PPP) in different countries, suggest that PPP could be an option in road traffic injury (RTI) prevention. The present study aims at investigating the applicability of PPP policy in RTI prevention in Iran based on the experts' perspectives. METHODS: This is a qualitative study with grounded theory approach which has been conducted in Tabriz University of Medical Sciences, Iran in 2018. The participants were 22 experts in the field of RTIs selected using purposive sampling method. Data were collected by semi-structured interviews and analyzed with content-analysis method. RESULTS: The results were classified under 5 main themes (applicability, scopes and services, challenges, advantages, and strategies) for applying PPP policy and 37 sub-themes. Due to the prevalence of RTIs, the present challenges in public sector, existence of qualified private sector, and successful experiences in other areas, there are opportunities for private sector partnership in prevention of RTIs. Private sector could participate in different scopes and services regarding RTI prevention, including road construction and maintenance, maintenance and provision of vehicles safety and public education. The main challenges including legislation issues, ambiguities in collaboration, political and organizational unsustainability, government's financial hardship and lack of experienced experts in the field of RTI. However, there are significant advantages including high efficiency in program implementation, covering the weaknesses of public sector, effective and efficient management on application of PPP in RTI prevention. The strategies include identifying and prioritizing the assignable activities, identifying the qualified private sector, developing PPP policies and legal frameworks, creating a common language between public and private parties, trying to meet the expectations of the private sector by public sector, developing a comprehensive and sound contract, and cultivating public culture to accept private sector in the field of RTI prevention. CONCLUSION: This study sought to determine whether PPP could be used as strategy to reduce the burden of RTIs in Iran. But it requires a lot of preliminary studies to provide the context and conditions for applying this policy.

Impact of varicocelectomy on urine dopamine value in patients with premature ejaculation and varicocele.

Dopamine is an important regulator of male sexual function and behaviour. Decreased levels of this substance have been observed in blood and seminal plasma of infertile men. Hence, this study was carried out to determine the impact of varicocelectomy on 24-hr urine dopamine values in patients with both premature ejaculation (PE) and varicocele. In this prospective study, 55 consecutive patients with premature ejaculation and grade 2 or 3 varicocele were enrolled. The urine dopamine level was measured in a 24-hr sample by HPLC method in a single laboratory centre. Two samples were gathered from each patient, one before and the other 1 month after varicocelectomy. The mean initial and final 24-hr urine dopamine levels were 259.6 ± 86.3 and 602.9 ± 88.4 micrograms, respectively, showing statistically significant increase (p = .0001), while there was no statistically significant difference between urine volume and creatinine. However, the change in intravaginal ejaculation latency time value was not statistically significant at this short time visit. According to our findings, varicocelectomy results in a significant increase in 24-hr urine dopamine levels in patients with premature ejaculation and varicocele. However, the effect of this change on premature ejaculation in the long term has yet to be determined.

Application of Human Acellular Breast Dermal Matrix (ABDM) in Implant-Based Breast Reconstruction: An Experimental Study.

BACKGROUND: The use of acellular dermal matrices (ABDM) has become more common for breast reconstruction to improve postoperative outcomes. We evaluated the efficacy of breast reconstruction by the application of human ABDM in a sheep model. METHODS: The sheep in group I (GI) (N = 4) underwent the following procedures on the right side: (1) breast reconstruction using human ABDM after total mastectomy, (2) human ABDM under the skin, near the breast area and on the left side, (3) fat injection and human ABDM after partial mastectomy, and (4) replacement of ABDM in the abdominal wall far from the breast. Sheep in group II (GII) (N = 4) underwent the following procedures. On the right side: (1) breast reconstruction using ABDM after total mastectomy, (2) replacement of ABDM under the skin, near the breast area, and on the left side, (3) application of vicryl synthetic mesh after partial mastectomy and (4) replacement of mesh under the skin, near the breast area. RESULTS: Histological evaluations of decellularized skin scaffolds demonstrated a collagen-based matrix with preserved ECM and complete nuclear removal. Histological evaluations of implanted ABDM demonstrated a viable matrix with fibroblast infiltration and revascularization in all follow-ups. The overall surgical complication rate was significantly lower in the ABDM implant under the skin and near the breast in both short- and long-term follow-ups. CONCLUSION: The results of this study demonstrated that the application of novel prepared ABDMs has promising outcomes for breast reconstruction to provide total coverage without the need for breast expansion before implant placement.

In-vivo trachea regeneration: fabrication of a tissue-engineered trachea in nude mice using the body as a natural bioreactor.

PURPOSE: To investigate the outcomes of implanting rat decellularized trachea scaffold (DTS) between the paravertebral muscles of nude mice using the body as a bioreactor for total graft recellularization. METHODS: The tracheas of four rats were aseptically resected and decellularized. To assess the efficiency of the decellularization procedure, all decellularized scaffolds and native control tissues were evaluated with scanning electron microscopy (SEM), DAPI staining, DNA quantification, biomechanical analyses and hydroxyproline measurement. They were then implanted between the paravertebral muscles of four nude mice. The biopsies were precisely evaluated at 1, 3, 6 and 12 months postoperatively for tracheal cartilage and soft tissue recellularization by staining for TTF1, CD34, S100 and leukocyte common antibody. RESULTS: Hematoxylin and eosin (H&E) staining, SEM and the tensile test confirmed the preservation of the tissue structure and the biophysical and biochemical properties of the DTS. The present study clearly demonstrated that the hydroxyproline content of the DTS was similar to that of the native tissue. On the other hand, in biopsy samples obtained after 12 months, histological evaluation showed superior organization and cell seeding in both the cartilage and connective tissues. CONCLUSION: This study demonstrated the feasibility of using a natural bioreactor for recellularizing DTS; this may have the potential to facilitate homologous transplantation for repairing segmental trachea defects.

Attitudes and Knowledge of Iranian Nurses about Hospice Care.

CONTEXT: Due to expansion of chronic diseases and increase of health care costs, there is a need for planning and delivering hospice care for patients in their final stages of life in Iran. The aim of the present study is to investigate the knowledge and attitudes of nurses about delivering hospice care for End of Life (EOL) patients. MATERIALS AND METHODS: This cross-sectional study was conducted in 2012 with a sample size of 200 nurses that were selected by convenient (available) sampling. The data collection instrument was a self-administered questionnaire whose validity was approved by experts' opinions and its reliability was approved by test-retest method. RESULTS: Among all participants of this study, 87% were female. The mean age of nurses was 32.00 ± 6.72. From all respondents 62% stated that they have no knowledge about hospice care and 80% declared that need for hospice care is increasing. Most of the participants felt that, appropriate services are not presented to patients in the final stages of their lives. About 80% believed that hospice care leads to reduction of health care costs, improvement of physical, mental and social health of patients and finally improvement of the quality of health care services. There was a significant relationship between age, employment history and level of education of nurses and their attitude and knowledge about how this service is provided. CONCLUSION: In view of the increase in chronic illnesses and the costs of caring, the need for provision of hospice care is felt more and more every day. However the awareness level of nurses about these services is low. Therefore the need for including these issues in nursing curriculum and holding scientific courses and seminars in this field is needed.

Electrochemical detection of the MT-ND6 gene and its enzymatic digestion: application in human genomic sample.

A simple electrochemical biosensor was developed for the detection of the mitochondrial NADH dehydrogenase 6 gene (MT-ND6) and its enzymatic digestion by BamHI enzyme. This biosensor was fabricated by modification of a glassy carbon electrode with gold nanoparticles (AuNPs/GCE) and a probe oligonucleotide (ssDNA/AuNPs/GCE). The probe, which is a thiolated segment of the MT-ND6 gene, was deposited by self-assembling immobilization on AuNPs/GCE. Two indicators including methylene blue (MB) and neutral red (NR) were used as the electroactive indicators and the electrochemical response of the modified electrode was measured by differential pulse voltammetry. The proposed biosensor can detect the complementary sequences of the MT-ND6 gene. Also the modified electrode was used for the detection of an enzymatic digestion process by BamHI enzyme. The electrochemical biosensor can detect the MT-ND6 gene and its enzymatic digestion in polymerase chain reaction (PCR)-amplified DNA extracted from human blood. Also the biosensor was used directly for detection of the MT-ND6 gene in all of the human genome.

One shot tract dilation for percutaneous nephrolithotomy: is it safe and effective in preschool children?

OBJECTIVE: To evaluate the safety and feasibility of percutaneous tract dilation by the one-stage method in preschool children. METHODS: Between April 2009 and February 2013, all preschool (<6 years) children who were candidates for percutaneous nephrolithotomy were enrolled in this prospective study. Patients were randomly assigned to dilation by serial metallic dilators (group I, 31 patients) or dilation by one-stage Amplatz according to Frattini et al. [J Endourol 2001;15:919-923] (group II, 31 patients). The primary endpoint of interest was fluoroscopy time. Secondary endpoints included tract creation and dilation time, success rate and complications. Stone-free status was defined as residuals ≤3 mm. RESULTS: Age, stone size, operation success and operation time were not significantly different between the studied groups. The most common stone composition was calcium oxalate in both groups. The mean ± standard deviation of access and fluoroscopy times in groups I and II were 7.3 ± 1.2 min vs. 5.9 ± 1.5 min (p > 0.05) and 70.0 ± 8.9 s vs. 22.0 ± 5.6 s (p < 0.001), respectively. Postoperative complications included one case of postoperative fever lasting less than 48 h in group I. CONCLUSIONS: Percutaneous tract dilation by the one-stage method is safe and effective. Also, it is associated with considerably less radiation exposure in preschool children.

Health system-related barriers to prenatal care management in low- and middle-income countries: a systematic review of the qualitative literature.

BACKGROUND: Appropriate prenatal care (PNC) is essential for improving maternal and infant health; nevertheless, millions of women in low- and middle-income countries (LMICs) do not receive it properly. The objective of this review is to identify and summarize the qualitative studies that report on health system-related barriers in PNC management in LMICs. METHODS: This systematic review was conducted in 2022. A range of electronic databases including PubMed, Web of Knowledge, CINHAL, SCOPUS, Embase, and Science Direct were searched for qualitative studies conducted in LMICs. The reference lists of eligible studies also were hand searched. The studies that reported health system-related barrier of PNC management from the perspectives of PNC stakeholders were considered for inclusion. Study quality assessment was performed applying the Critical Appraisal Skills Programme (CASP) checklist, and thematic analyses performed. RESULTS: Of the 32 included studies, 25 (78%) were published either in or after 2013. The total population sample included 1677 participants including 629 pregnant women, 122 mothers, 240 healthcare providers, 54 key informed, 164 women of childbearing age, 380 community members, and 88 participants from other groups (such as male partners and relatives). Of 32 studies meeting inclusion criteria, four major themes emerged: (1) healthcare provider-related issues; (2) service delivery issues; (3) inaccessible PNC; and (4) poor PNC infrastructure. CONCLUSION: This systematic review provided essential findings regarding PNC barriers in LMICs to help inform the development of effective PNC strategies and public policy programs.

Comparison of Combined Guidance of Fluoroscopy and Ultrasonography in Total Tubeless Percutaneous Nephrolithotomy with the Standard Method: A Randomized Clinical Trial.

OBJECTIVE: utilizing the combination of fluoroscopy and ultrasonography during Percutaneous Nephrolithotomy (PCNL) to minimize radiation exposure. METHODS: In this randomized clinical trial, 118 patients with urinary stones who were candidates for PCNL surgery in the prone position were selected and divided into two groups (with an allocation ratio of 1:1). Cases were grouped according to whether ultrasonography was used for renal tract dilation and Amplatz sheath placement. The number of attempts to establish proper renal access, the time interval between access to the targeted calyx and nephroscope entrance, and the Clavien-Dindo score were collected. RESULTS: The mean age of all patients was 46.12±11.28 (45.6±11.2 in the total fluoroscopy group and 46.5±11.4 in the combined group) years (20-66). The intergroup differences in the baseline features were not significant. The mean duration of fluoroscopy time was significantly reduced in the combined guidance group (36.22±10.73 vs. 23.05±8.94 seconds, [P-value = 0.001]). Moreover, the difference in the distribution of Amplatz location on the nephroscopy time was meaningful (P-value = 0.016). However, intergroup differences in the number of attempts to successful puncture, length of hospitalization, recovery time, and postoperative complications, including gross hematuria duration, blood loss volume, pack cells requirement, pain score immediately and 6 hours after the surgery, and Clavien-Dindo score were not meaningful. CONCLUSION: It can be concluded that the use of ultrasound with X-ray in prone PCNL compared to the use of X-rays alone can significantly reduce the duration of radiation without increasing the risk of intra-operative and postoperative detrimental events.

Comparative Efficacy of Different Classes of Antiemetic Medications for the Prevention of Nausea and Vomiting in Cesarean Section: A Network Meta-Analysis.

Background: Antiemetic medications have been associated with the prevention of nausea and vomiting in cesarean section, although less is known about the comparative efficacy of different medication classes. Methods: We conducted a systematic review with network meta-analyses to compare and rank antiemetic medication classes (5-HT3 receptor antagonists, dopamine receptor antagonists, corticosteroids, antihistamines, anticholinergic agents, sedatives, and opioid antagonists or partial agonists) in terms of preventing intra- and postoperative nausea and vomiting among patients undergoing cesarean section. We included all randomized controlled trials (RCTs) that evaluated any antiemetic medication classes' treatment for target outcomes. Network meta-analysis was conducted with a frequentist approach using the R netmeta package. A total of 58 trials were included (6,665 women undergoing cesarean section; mean age, 28.1 years). Results: Compared with placebo, all interventions reduced the odds of intraoperative nausea (except antihistamines), intraoperative vomiting (except antihistamines), postoperative nausea (except anticholinergic agents and opioid antagonists), and postoperative vomiting (except opioid antagonists). In terms of intraoperative nausea and both intra- and postoperative vomiting, sedatives ranked first among other medication classes. Conclusions: The relative effect sizes for various classes of antiemetic medication in preventing nausea and vomiting in the cesarean section were modeled using the principles of network meta-analysis which may facilitate informed clinical decision-making.

Application of nanosized MCM-41 to fabrication of a nanostructured electrochemical sensor for the simultaneous determination of levodopa and carbidopa.

A novel carbon paste electrode modified with nanosized mesoporous MCM-41 was prepared, and used as an electrochemical sensor to study the electro oxidation of levodopa (LD), carbidopa (CD) and their mixtures. Using differential pulse voltammetry (DPV), a highly selective and simultaneous determination of LD and CD has been explored at the modified electrode. The electrochemical sensor displayed a good resolving function for the overlapping voltammetric responses of LD and CD into two separate peaks with a potential difference of 370 mV. DPV peak currents of LD increased linearly with concentration over the 0.13 µM to 1250.00 µM range and exhibited a detection limit of 0.072 µM. Also, the proposed electrochemical sensor was used for the determination of LD and CD in some real samples, using the standard addition method.

A Systematic Review and Meta-Analysis of the Prevalence of Malnutrition Among 6-14-Year-Old Children in Iran.

Background: Malnutrition is a major public health issue worldwide. It has significant consequences, including weakened immune systems, which may lead to increased incidences of infectious disease and higher mortality, particularly in children. A systematic review and meta-analysis were conducted to estimate the overall prevalence of malnutrition (wasting, underweight, and stunting) among children of 6-14 years of age in Iran. Methods: Data were collected in 2018 based on searches of the PubMed, Science Direct, Scopus, Google Scholar, Science Information Database (SID), Magiran, Irandoc, and Iranmedex databases using the following keywords: childhood, childhood malnutrition, children, nutrition, malnutrition, wasting, underweight, stunting, child, student, boy, girl, cause, prevalence, and Iran, in order to identify studies eligible for inclusion in the review. Comprehensive Meta-Analysis, version 2 (CMA: 2) was used to estimate the overall prevalence of malnutrition. Results: Nine out of 328 articles were included in our analyses. The overall of wasting among children of 6-14 years of age in Iran based on the random-effects model (according to nine studies and 18,296 participants) was 12.5% (95% Confidence Interval, 7.1-21.2). The overall prevalence of underweight based on the random-effects model (according to 10 studies and 19,185 participants) was 19% (95% CI, 8.1-38.6). Also, the overall prevalence of stunting based on the random-effects model (according to 10 studies and 19,185 participants) was 20% (95% CI, 9.4-37.8). Conclusions: The results of this study show that the prevalence of malnutrition among 6-14-year-old children in Iran is similar to the global average. We need solutions that can be used for both prevention and reduction of malnutrition, especially in areas with middle or low socioeconomic status. It is necessary to identify factors associated with malnutrition in various geographic regions in order to implement appropriate programs based on factors with the highest impact in each region.
