Abstract
The escalating presence of microplastics (MPs) in wastewater necessitates the investigation of effective tertiary treatment process. Forward osmosis (FO) emerges as an effective non-pressurized membrane process, however, for the effective implementation of FO systems, the development of fouling-resistance FO membranes with high-performance is essential. This study focuses on the integration of MWCNT/UiO-66-NH2 as metal-organic frameworks (MOFs) and multi-wall carbon nanotubes (MWCNT) nanocomposites in thin film composite (TFC) FO membranes, harnessing the synergistic power of hybrid nanoparticles in FO membranes. The results showed that the addition of MWCNT/UiO-66-NH2 in the aqueous phase during polyamide formation changed the polyamide surface structure, and enhanced membranes' hydrophilicity by 44%. The water flux of the modified FO membrane incorporated with 0.1 wt.% MWCNTs/UiO-66-NH2 increased by 67% and the reverse salt flux decreased by 22% as in comparison with the control membrane. Moreover, the modified membrane showed improved antifouling behavior against both organic foulant and MPs. The MWCNT/UiO-66-NH2 membrane experienced 35% flux decline while the control membrane experienced 65% flux decline. This proves that the integration of MWCNT/UiO-66-NH2 nanoparticles into TFC FO membranes is a viable approach in creating advanced FO membranes with high antifouling propensity with potential to be expanded further to other membrane applications.

Abstract
Widespread contamination by heavy metals (HMs) and dyes poses a major health risk to people and ecosystems requiring effective treatment. In this work, rice husk (RH) and shrimp shells were extracted to obtain amorphous silica and chitosan, respectively, which were utilized to produce nano-chitosan-coated silica (NCCS). To ensure the stability of the nanoparticles, silica was freeze-dried after being coated with nano-chitosan. Functional groups (-NH2, -OH, P]O) from chitosan nanoparticles (CNPs) were introduced to the surface of silica during this process. Dyes such as brilliant green (BG), methylene blue (MB) and reactive brown (RB) as well as HMs (Cr6+, Pb2+, Cd2+, Ni2+) were removed by adsorbents. CNPs showed the highest adsorption capacity for RB (59.52 mg/g) among dyes and Cr6+ (42.55 mg/g) among HMs. CNPs showed the highest adsorption capacity for HMs among different adsorbents. Although NCCS and CNPs showed similar adsorption capabilities for HMs and dyes, NCCS showed the best stability. The adsorption performance decreased as RB > Cr6+ > MB > BG > Pb2+ > Cd2+ > Ni2+. The adsorption reactions followed both pseudo-first-order and second-order kinetics, and was spontaneous from thermodynamic analysis. In summary, the waste-derived adsorbents demonstrated excellent potential for removing HMs and dyes from water, while supporting effective management solid waste.

Abstract
The development of biodegradable active packaging films with hydrophobic characteristics is vital for extending the shelf life of food and reducing the reliance on petroleum-based plastics. In this study, novel hydrophobic cerium-based metal-organic framework (Ce-MOF) nanoparticles were successfully synthesized. The Ce-MOF nanoparticles were then incorporated into the cassava starch matrix at varying concentrations (0.5 %, 1.5 %, 3 %, and 4 % w/w of total solid) to fabricate cassava-based active packaging films via the solution casting technique. The influence of Ce-MOF on the morphology, thermal attributes, and physicochemical properties of the cassava film was subsequently determined through further analyses. Biomedical analysis including antioxidant activity and the cellular morphology evaluation in the presence of the films was also conducted. The results demonstrated that the consistent dispersion of Ce-MOF nanofillers within the cassava matrix led to a significant enhancement in the film's crystallinity, thermal stability, antioxidant activity, biocompatibility, and hydrophobicity. The introduction of Ce-MOF also contributed to the film's reduced water solubility. Considering these outcomes, the developed cassava/Ce-MOF films undoubtedly have significant potential for active food packaging applications.

Abstract
The aim of this work was to fabricate an intelligent film using sago starch incorporated with the natural source of anthocyanins from the Bauhinia Kockiana flower and use it to monitor the freshness of coconut milk. The films were developed using the casting method that included the addition of the different concentrations (0, 5, 10, 15 mg) of Bauhinia Kockiana extract (BKE) obtained using a solvent. The anthocyanin content of Bauhinia Kockiana was 262.17 ± 9.28 mg/100 g of fresh flowers. The spectral characteristics of BKE solutions, cross-section morphology, physiochemical, barrier, and mechanical properties, and the colour variations of films in different pH buffers were investigated. Films having the highest BKE concentration demonstrated the roughest structure and highest thickness (0.16 mm), moisture content (9.72 %), swelling index (435.83 %), water solubility (31.20 %), and elongation at break (262.32 %) compared to the other films. While monitoring the freshness of coconut milk for 16 h, BKE15 showed remarkable visible colour changes (from beige to dark brown), and the pH of coconut milk dropped from 6.21 to 4.56. Therefore, sago starch film incorporated with BKE has excellent potential to act as an intelligent pH film in monitoring the freshness of coconut milk.

Abstract
The recent advancements in fabricating forward osmosis (FO) membranes have shown promising results in desalination and water treatment. Different methods have been applied to improve FO performance, such as using mixed or new draw solutions, enhancing the recovery of draw solutions, membrane modification, and developing FO-hybrid systems. However, reliable methods to address the current issues, including reverse salt flux, fouling, and antibacterial activities, are still in progress. In recent decades, surface modification has been applied to different membrane processes, including FO membranes. Introducing nanochannels, bioparticles, new monomers, and hydrophilic-based materials to the surface layer of FO membranes has significantly impacted their performance and efficiency and resulted in better control over fouling and concentration polarization (CP) in these membranes. This review critically investigates the recent developments in FO membrane processes and fabrication techniques for FO surface-layer modification. In addition, this study focuses on the latest materials and structures used for the surface modification of FO membranes. Finally, the current challenges, gaps, and suggestions for future studies in this field have been discussed in detail.

Abstract
Non-biodegradability and disposal problems are the major challenges associated with synthetic plastic packaging. This review article discusses a new generation of biodegradable active and smart packaging based on porous nanomaterials (PNMs), which maintains the quality and freshness of food products while meeting biodegradability requirements. PNMs have recently gained significant attention in the field of food packaging due to their large surface area, peculiar structures, functional flexibility, and thermal stability. We present for the first time the recently published literature on the incorporation of various PNMs into renewable materials to develop advanced, environmentally friendly, and high-quality packaging technology. Various emerging packaging technologies are discussed in this review, along with their advantages and disadvantages. Moreover, it provides general information about PNMs, their characterization, and fabrication methods. It also briefly describes the effects of different PNMs on the functionality of biopolymeric films. Furthermore, we examined how smart packaging loaded with PNMs can improve food shelf life and reduce food waste. The results indicate that PNMs play a critical role in improving the antimicrobial, thermal, physicochemical, and mechanical properties of natural packaging materials. These tailor-made materials can simultaneously extend the shelf life of food while reducing plastic usage and food waste.

Abstract
Microplastics (MPs) are emerging contaminants that are abundantly present in the influent and effluent of wastewater treatment plants (WWTPs). Forward osmosis (FO) is an advanced treatment technology with potential applications in WWTPs. The presence of MPs in WWTP effluents can contribute to FO fouling and performance deterioration. This study focuses on FO membrane fouling by MPs of different sizes, and the interactional impacts of MPs and Humic acid (HA) (as the most common organic foulant in WWTPs) on FO membrane performance. The synergistic effect of combined MPs and HA fouling is shown to cause higher flux decline for FO membranes than that of HA or MPs alone. Reverse salt flux increased in the presence of MPs, and decreased when HA was present. Further, full flux recovery was obtained for all fouled membranes after hydraulic cleaning. This indicates the efficiency of FO systems for treating wastewater with high fouling potential. This study highlights the necessity of considering MPs in studying fouling behaviour, and for mitigation strategies of membranes used in WWT. The fundamentals created here can be further extended to other membrane-assisted separation processes.

Abstract
Canine parvovirus infection is the most highly infectious in dogs younger than six months. Our study aimed to design and optimize an In-house PCR Assay for Rapid Detection of parvovirus type 2 and compares it with REAL-TIME PCR and LAMP Assay and phylogenetic analysis. The virulence gene selected for the categories was vp2 for CPV-2. PCR products were cloned in pTZ57R/T plasmid for preparation of positive control. Determination of the specificity of primers was done with the negative control virus genomes, and the limit of detection was determined for the Homemade PCR, REAL-TIME PCR, LAMP, and to perform a phylogenetic study using partial vp2 gene sequences. Added analysis of PCR products using agarose gel electrophoresis for the vp2 gene showed 485bp, and GAPDH 900 bp bands, respective amplification using negative control genomes as template was negative. The least detectable copy number for the vp2 gene in a 25 µl PCR reaction equals 19 copies by homemade PCR, LAMP, and REAL-TIME PCR 25 and 21 copies, respectively. The phylogenetic analysis for the five field sequences formed three distinct clusters. The in-house PCR has advantages such as high specificity, sensitivity, and the ability to detect major CPV-2 pathogens. This assay may replace the previous laboratory methods and work as an essential supplement to the more time-consuming assays. Phylogenetic analysis is necessary for epidemiological studies to control and prevent disease.

Abstract
Consumer demands to utilize environmentally friendly packaging have led researchers to develop packaging materials from naturally derived resources. In recent years, plant protein-based films as a replacement for synthetic plastics have attracted the attention of the global food packaging industry due to their biodegradability and unique properties. Biopolymer-based films need a filler to show improved packaging properties. One of the latest strategies introduced to food packaging technology is the production of nanocomposite films which are multiphase materials containing a filler with at least one dimension less than 100 nm. This review provides the recent findings on plant-based protein films as biodegradable materials that can be combined with nanoparticles that are applicable to food packaging. Moreover, it investigates the characterization of nanocomposite plant-based protein films/edible coatings. It also briefly describes the application of plant-based protein nanocomposite films/coating on fruits/vegetables, meat and seafood products, and some other foods. The results indicate that the functional performance, barrier, mechanical, optical, thermal and antimicrobial properties of plant protein-based materials can be extended by incorporating nanomaterials. Recent reports provide a better understanding of how incorporating nanomaterials into plant protein-based biopolymers leads to an increase in the shelf life of food products during storage time.

Abstract
Recently, the research and innovation to produce raw materials from microbial processes has gained much attention due to their economic and environmental impacts. Lactic acid is a very important microbial product due to its wide application in the food, pharmaceutical, cosmetic, and chemical industries. In the current study, poly (L-lactic acid) (PLLA) was produced by the ring opening polymerization (ROP) technique of L-lactic acid recovered from whey fermentation, and was used for the production of nanocomposites films reinforced with chitosan nanoparticles (CNPs) (average diameter ca. 100–200 nm). Three different CNPs concentrations, namely 1, 3, and 5% w/w, were tested, and their influence on the physical, mechanical, thermal, antibacterial and structural attributes of PLLA film was assessed. The results showed that the addition of CNPs up to 3% caused a significant improvement in water vapor permeability, appearance, tensile strength and elongation at break. The antibacterial properties of nanocomposites followed a dose-depended pattern as a result of CNPs addition. Therefore, the best inhibitory effects on Escherichia coli and Staphylococcus aureus was made by the addition of 5% of CNPs and lower dosages slightly affected the growth of pathogens or didn't cause any inhibitory effects (in 1% of CNPs). It can be concluded that the incorporation of CNPs into the PLLA matrix allows to improve the structural, thermal, physical, mechanical and antibacterial properties of the polymer, generating promising systems for food packaging and biomedical applications.

Abstract
The emergence and accumulation of microplastics (MPs) in various aquatic environments have recently raised significant concerns. Wastewater treatment plants (WWTPs) have been identified as one of the major sources of MPs discharge to the environment, implying a substantial need to improve advanced techniques for more efficient removal of MPs. Polymeric membranes have been proven effective in MPs removal. However, fouling is the main drawback of membrane processes and MPs can foul the membranes due to their small size and specific surface properties. Hence, it is important to investigate the impacts of MPs on membrane fouling to develop efficient membrane-based techniques for MPs removal. Although membrane technologies have a high potential for MPs removal, the interaction of MPs with membranes and their fouling effects have not been critically reviewed. The purpose of this paper is to provide a state-of-the-art review of MPs interaction with membranes and facilitate a better understanding of the relevant limitations and prospects of the membrane technologies. The first section of this paper is dedicated to a review of recent studies on MPs occurrence in WWTPs aiming to determine the most frequent MPs. This is followed by a summary of recent studies on MPs removal using membranes and discussions on the impact of MPs on membrane fouling and other probable issues (abrasion, concentration polarisation, biofouling, etc.). Finally, some recommendations for further research in this area are highlighted. This study serves as a valuable reference for future research on the development of anti-fouling membranes considering these new emerging contaminates.

Abstract
In this study, hematite graphene oxide (αFe2O3-GO) powder nanocomposites and thin-film hematite graphene oxide (αFe2O3-GO) were synthesized for application in the removal of Rhodamine B (RhB) from textile wastewater. αFe2O3-GO nanomaterials were placed onto the FTO substrate to form a thin layer of nanocomposites. Different analysis including XRD, FTIR, Raman spectra, XPS, and FESEM were done to analyze the morphology, structure, and properties of the synthesized composites as well as the chemical interactions of αFe2O3 with GO. The photocatalytic performance of two synthesized composites was compared with different concentrations of αFe2O3-GO. The results showed that powder nanocomposites are more effective than thin-film composites for the removal of RhB dye. αFe2O3-GO-5% powder nanocomposites removed over 64% of dye while thin-film nanocomposites had less removal efficiencies with just under 47% removal rate. The reusability test was done for both materials in which αFe2O3-GO-5% powder nanocomposites removed a higher rate of dye (up to 63%) in more cycles (6 cycles).

Abstract
Abstract
Introduction
Kashmir is a resource limited, region of India having its own distinctive regional challenges, operational limitations and poor accessibility of remote areas to health care. Utilizing smart phones as a medium for providing access to the optimum cardiac care in the remotest of the areas of our region served as a platform for SAVE HEART INITIATIVE (SHI) launched in the form of Social Media Whatsapp Group connecting peripheral hospitals (spokes) in the Kashmir region to experts (Hub).
Material and methods
SHI, a novel initiative was started voluntarily by a team of cardiologists and physicians. All the government hospitals along with their Emergency (ER) teams were roped in, integrated with expert physicians and cardiologists via whats app based technology creating a virtual cardiac ER facility and a CYBER HUB where teams of experts lended optimum support to all the peripheral hospitals of the region which acted as CYBER SPOKES of the initiative. Simultaneously all the peripheral hospitals upgraded to a functional Emergency room with all the emergency drugs available including the clot busters as streptokinase and vital anti arrhythmic drugs free of cost. Emergency room proformas, algorithms, protocols were created and standardized to aid in management. CME's regarding cardiac emergencies and response workshops were organized at regional institutes regularly for capacity building locally. The decision to use whatsapp as technology in medical care was taken due to its unique features of being readily available, handy technology, and as it could transfer all data in form of text, images, audios, visuals to and from the cyber spokes and cyber hubs respectively.
Results
Within 500 days of the initiative about 130 hospitals and 1200 doctors were taken on board. A total of 38000 ECGs were analyzed till date wherein the average response time in this social media group to any case was 1–2 minutes mostly and the diagnostic delays decreased to minimum. This initiative managed 950 STEMI's with thrombolysis, 2723 NSTEMI, 5320 arrhythmias, 345 heart blocks, 16 pulmonary thrombo-embolisms, 53 PCI decisions.
Conclusion
Our experiment demonstrated the feasibility of the approach adopted for better cardiac care that reached the poorest living in far flung area without any extra burden to the state exchequer. SHI reduced morbidity, mortality; CCU occupancy rate in tertiary care brought down undue referrals and established a vibrant patient tracking system in the region depicting its success. Using Smartphone based technology in time sensitive cardiac events seems to be the most vibrant, novel and viable option being available, portable, efficient, and cost-effective, with least technical glitches. It seems to be the way forward in providing optimum and timely treatment in all acute cardiac emergencies in resource deficient regions as Kashmir.

Abstract
Background Evidence from a retrospective analysis of multiple large phase iii trials suggested that primary tumour location (ptl) in RAS wild-type metastatic colorectal cancer (wtRAS mcrc) might have predictive value with respect to response to drug therapies. Recent studies also show a potential preferential benefit for epidermal growth factor inhibitors (egfris) for left-sided tumours. In the present study, we aimed to determine the incremental cost-effectiveness ratio (icer) for the first-line use of an egfri for patients with left-sided wtRAS mcrc. Methods We developed a state-transition model to determine the cost effectiveness of alternative treatment strategies in patients with left-sided mcrc:■ Standard of care■ Use of an egfri in first-line therapyThe cohort for the study consisted of patients diagnosed with unresectable wtRAS mcrc with an indication for chemotherapy and previously documented ptl. Model parameters were obtained from the published literature and calibration. The perspective was that of a provincial ministry of health in Canada. We used a 5-year time horizon and an annual discount rate of 1.5%. Results Selecting patients for first-line egfri treatment based on left-sided location of their colorectal primary tumour was more effective than the standard of care, resulting in an increase in quality-adjusted life-years (qalys) of 0.226 (or 0.644 life-years gained). However, the strategy was also more expensive, costing an average of $60,639 more per patient treated. The resulting icer was $268,094 per qaly. A 35% price reduction in the cost of egfri would be needed to make this strategy cost-effective at a willingness-to-pay threshold (wtp) of $100,000 per qaly. Conclusions Selective use of an egfri based on ptl was more cost-effective than unselected use of those agents; however, based on traditional wtp thresholds, it was still not cost-effective. While awaiting the elucidation of more precise predictive biomarkers that might improve cost-effectiveness, the price of egfris could be reduced to meet the wtp threshold.

Abstract
Interferon lambda 3 (IFNL3) and epidermal growth factor receptor (EGFR) single nucleotide polymorphisms (SNPs) may play a key role in the spontaneous clearance of hepatitis C virus (HCV) and treatment responses. The aim of this study was to evaluate the effect of IFNL3 SNPs and EGFR rs11506105 on treatment outcomes in patients with chronic HCV (CHC). IFNL3 SNPs and EGFR rs11506105 were genotyped by PCR-restriction fragment length polymorphism and PCR-sequencing, respectively, in 235 naïve patients with CHC infection. The frequency of rapid virologic response (RVR), complete early virologic response (cEVR) and sustained virologic response (SVR) were 52.3%, 76.2% and 64.7% respectively. The results of this study showed that RVR was associated with ALT (P=0.015), AST (P=0.020), IFNL3 rs12979860 (CC) (P=0.043), rs12980275 (AA) (P=1 × 10-4), and EGFR rs11506105 (AA) (P=0.010), and IFNL3 rs12979860 (CC) (P=0.048), rs12980275 (AA) (P=0.022), and EGFR rs11506105 (AA) (P=0.006) were correlated with cEVR. HCV genotype (P=0.007), IFNL3 rs12979860 (CC) (P=0.023), IFNL3 rs12980275 (AA) (P=1 × 10-4), EGFR rs11506105 (AA) (P=0.005), RVR (P=1 × 10-4), and cEVR (P=0.003) were significant predictors for SVR. These results, for the first time, revealed that beside IFNL3 SNPs, EGFR rs11506105 is strongly associated with RVR, cEVR and SVR. EGFR rs11506105 besides IFNL3 SNPs could predict treatment responses in CHC patients.

Abstract
Thermoresponsive microgels with carboxylic acid functionalization have been recently introduced as an attractive draw agent for forward osmosis (FO) desalination, where the microgels showed promising water flux and water recovery performance. In this study, various comonomers containing different carboxylic acid and sulfonic acid functional groups were copolymerized with N-isopropylacrylamide (NP) to yield a series of functionalized thermoresponsive microgels possessing different acidic groups and hydrophobicities. The purified microgels were examined as the draw agents for FO application, and the results show the response of water flux and water recovery was significantly affected by various acidic comonomers. The thermoresponsive microgel with itaconic acid shows the best overall performance with an initial water flux of 44.8 LMH, water recovery up to 47.2% and apparent water flux of 3.1 LMH. This study shows that the incorporation of hydrophilic dicarboxylic acid functional groups into the microgels leads to the enhancement on water adsorption and overall performance. Our work elucidates in detail on the structure-property relationship of thermoresponsive microgels in their applications as FO draw agents and would be beneficial for future design and development of high performance FO desalination.

Abstract
This study was conducted to assess the effect of melatonin on the structure of testis and spermatogenesis dynamics in neonate vitrified testis grafts. Neonate vitrified testes, candidates for transplantation heterotopically to experiment or control groups, were warmed in thawing media which had or did not have a supplement of 100 μM melatonin, respectively. Following transplantation, melatonin (20 mg/ /kg/day) or saline solution was intraperitoneally injected into the treated and the non-treated groups, respectively. The initiating spermatogenesis, spermatogonia survival, and structure of tissue in the testis graft were examined. Cell apoptosis (TUNEL assay) and proliferation (Brdu assay) in germ cells were determined. Histological studies revealed the dynamic of the spermatogenesis process in the vitrified testis graft. However, dilation of the lumen accompanied by a disorganised epithelium in the non-treated group was higher than in the treated group. Furthermore, the proportion of apoptotic germ cells together with a reduced proportion of proliferated germ cells was higher in the non-treated group than in the treated group. Overall, the number of seminiferous tubules in the testes grafts of both groups remained steady. However, the non-treated testes grafts contained more damaged seminiferous tubules than the treated ones. The thickness of the seminiferous tubules was greater in the melatonin treated group than in the non-treated group. In fact, the thickness of germinal epithelium was significantly higher in the treated group than in the non-treated group. The study may show a positive effect from melatonin resulting in more grafts restoring puberty. Furthermore, the associated increase in the healthy number of seminiferous tubules suggests that melatonin may have a preventative ischaemia/antioxidant role and in fact may be useful to initiate the spermatogenesis process.

Abstract
BACKGROUND Although in the last few years there has been an increasing attention to the problem of landmines, to date, the implications of women being victims of landmine has not been duly dealt with in the world including Iran, which is estimated to be the second most landmine infested country in the world. Still, provinces by the west border of Iran, 18 years after cessation of Iraq-Iran war suffer from the burden of vast areas, highly infested with landmines. This study aimed to provide a gender focused insight into landmine accidents in Iran METHODS In this retrospective study, women with documented deaths or injuries due to landmine and/or unexploded ordnances (UXO) explosions as documented in their medical records between Jul 1988 (after ceasefire) and Feb 2003 were studied in 5 western provinces of Iran. Data was analyzed by SPSS for Windows Version 11. P value under 0.05 was considered statistically significant RESULTS During the 14-year study period, 252 women from 5 western provinces of Iran were reported to have injuries or death due to landmine and UXOs. All of the victims were civilians and the majority of them (47.6%) had one or more amputations. Most of them were injured in the period between1994 and 1998. The majority of the patients were young. CONCLUSION Women who should take care of themselves as well as their families are more prone to sufferings inflicted by landmines and UXO.

Abstract
We studied motorcycle-related injuries in Tehran from 23 August 1999 to 21 September 2000 in 6 hospitals. Data were obtained from the trauma registry and questionnaires completed by trained physicians. Of a total of 8500 patients with trauma injuries, 1332 were motorcyclists, with a male to female ratio of 15:1. Of these, 1226 patients were driving the motorcycle at the time of the accident and 75 were pillion passengers. Crashes involving another vehicle were the commonest kind of accident (72.5%). Helmet use was noted in only 8.6% of cases. There were 28 fatalities and head injuries were the prominent cause of death. Of those who died, none had been wearing a helmet at time of the crash. Only 2.7% of helmeted riders sustained a head injury, compared with 11.2% of riders without a helmet. The commonest musculoskeletal injury was fracture: tibial fracture with 509 cases (49.8%) comprised the largest proportion.

Abstract
Although falls from trees are rare, the consequences can be severe. Over 13 months in 6 hospitals in Tehran 49 (0.57%) of 8500 registered trauma patients had fallen from trees. The mean age was 31 years (range 6 to 74 years) and 21 (42.9%) were aged < 20 years. Home and recreational/sports grounds were the most common sites of trauma. Most falls occurred during leisure time; only 3 (6.1%) were occupation-related. Eleven patients (22.4%) sustained a fracture of the spinal column; 2 of them became permanently paraplegic and 2 others who had severe thoracic vertebral fractures and paraplegia on first observation were transferred to other hospitals for treatment. Due to the severity of this type of injury, especially among the young, effective preventive efforts may be necessary.

Abstract
Trauma now attracts more attention than ever before as a major cause of death and disability in developed and developing countries. To describe the characteristics and outcome of injuries in our environment, and to identify and discuss possible preventative and management protocols that may also be adopted in developing countries, we designed a prospective study on all trauma patients consecutively attending three emergency departments over a period of 1 year in Tehran, Iran. Among the total of 58013 patients studied, workers were the most vulnerable occupational group and deserve special preventative measures. The high frequency of traffic (especially pedestrian) accidents suggests that considerable progress is required in preventing these injuries. Our hospitalized patients were comparable with patients in the Major Trauma Outcome Study (m=0.890), and the z (-15.485) and w (-2.447) statistics showed an unsatisfactory quality of care, which may partly be due to less usage of ambulances, the long time of transportation to hospital, frequent referrals between centres, and delayed and inadequate resuscitation by the emergency services. Based on our findings and the fact that the positive effect of trauma systems on outcome has been well documented, we suggest that an integrated trauma system be established in Tehran to improve the quality of trauma care.
