Aims: Landfill leachate contains many pollutants including chemical oxygen demand (COD), biological oxygen demand, ammonia nitrogen, organic matter, minerals, and toxins. Given the importance of COD removal from landfill leachate, this study was conducted to evaluate and compare different methods used for the removal of COD from leachate. Materials and Methods: This study was conducted as a narrative review using keywords of leachate, COD, landfill in related journals issued in scientific databases such as Web of Science, PubMed, SID, and Google Scholar. We reviewed different aspects of COD removal from leachate to find better options in this respect. Results: The highest rate of COD removal was observed for batch reactor methods of anaerobic and aerobic granular activated carbon and electro Fenton by 98.4% COD removal, and the lowest one was 22.7% for the electro-Fenton method. The most commonly used methods for removing COD from solidwaste leachate have been physical and chemical methods. Conclusion: This study showed that a wide range method has been used to remove COD from leachate. It seems that combined methods are more effective to reduce the content of leachate COD. Besides, methods such as Fenton and absorption are more preferable because of simple application and low energy consumption.

Aims: Latex sensitivity has been a concern for health-care workers in recent years. Due to the excessive exposure to latex products in the operating room, the personnel of this department are exposed to high sensitivity to these products. Therefore, the present study was conducted to investigate the prevalence of latex sensitivity among operating room personnel. Materials and Methods: This systematic review and meta-analysis conducted based on a Preferred Reporting Items for Systematic Reviews and Meta-Analysis checklist. The present study researchers explored four international databases, namely Medline/PubMed, ProQuest, Scopus, and Embase in February 2020. The selected keywords for international databases were classified into three categories (a) operating room personnel, (b) latex sensitivity, and (c) prevalence. The collected data were entered into the EndNote X8 software and analytical analysis was performed by STATA statistical software version 12. Results: Seventy-five articles were found by searching for databases. After several screening steps, 12 articles entered the final analysis. The results show that the prevalence of latex sensitivity in total is 14.76 (confidence interval 95%: 9.27–20.25). Meta-regression results showed that the relationship between the years of study and the prevalence of latex sensitivity is not statistically significant (P = 0.222). Conclusion: The results of the present study showed that sensitivity to latex is significantly prevalent among operating room staff. Due to the importance of sterility and sensitive working conditions in the operating room, as well as frequent contact with latex products, it is important to pay attention to the side effects caused by latex powder.

Nazila Esmaeili, Parviz Asgari, Naser Seraj Khorami, Saeed Bakhtiarpour
Aims: According to the World Health Organization, migraine is the twentieth rank among all disability-causing disorders. The present study aimed to evaluate the effectiveness of acceptance and commitment therapy (ACT) on perfectionism and resilience in migraine patients. Materials and Methods: The research method was semi-experimental with a pretest–posttest design and a control group. The statistical population of the study included all patients with migraine who presented to neurologists in Tehran in the fall of 2018, from which thirty patients were selected using convenience sampling method and randomly assigned to experimental and control groups. The data were collected by the Connor-Davidson Resilience Scale and Ahvaz Perfectionism Scale (APS). The experimental group received ACT in eight weekly sessions, while the control group was on the waiting list. The data were analyzed using the multivariate analysis of covariance. Results: Findings showed that there was a difference between the control and experimental groups in perfectionism and resilience means at the posttest level. Regarding the means of the variables after the intervention, results showed that those patients who received the intervention had more resilience and lower perfectionism than those who were in the waitlist control group. Therefore, the ACT was effective on perfectionism (P < 0.001) and resilience (P < 0.001) of migraine patients. Conclusion: Given the effectiveness of ACT, it is recommended to use the ACT as a supplementary therapy with medical treatments for migraine patients. Theoretical and practical implications are discussed in the discussion section.

Aim: This study aimed to compare family planning (FP) services in urban and rural health facilities in Nigeria. Materials and Methods: The study is a cross-sectional study conducted in 204 rural and 198 urban health facilities comprising 182 primary and 216 secondary facilities in Nigeria. A FP client was randomly selected from each of the facilities, and structure questionnaires were used to collect information from them. Data collected include the various types of contraception available, waiting time, and satisfaction with services. Data were analyzed with IBM-SPSS Statistics Version 25.0. Results: The most requested contraceptives methods were injectables (48.2%) and oral contraceptives (22.6%). Most clients in both the rural (76.0%) and urban (76.3%) waited <30 min to see health providers. However, 20.1% of clients in urban health facilities waited for 30–60 min compared to 15.2% in rural areas (P < 0.05). The overall quality of service was 90.0% in rural and 92.9% in urban areas (P < 0.05). Over 90% of both rural and urban clients were satisfied with how providers received them, cleanliness of the facilities, and time spent with care providers but less than half (<50%) were satisfied with the services they received. Significantly higher quality of services was reported by clients in the northern parts of Nigeria (6.74/7) (P < 0.001), whereas client's satisfaction was slightly higher in the South (6.56/7) (P > 0.05). Conclusion: There is a need for an improvement in waiting time and quality of services offered in health facilities. Policymakers should to carry out regular supervision of health facilities and ensure availability of contraceptives in the health facilities at affordable prices in order to improve FP uptake in Nigeria.

Mahdi Malakoutikhah, Hadiseh Rabiei, Asma Zare, Amir Omidvar
Aims: Environmental conditions affect workers health and performance. The present study aimed to investigate the simultaneous effect of ambient temperature and light intensity on human error. Materials and Methods: This cross-sectional study was conducted on 50 students from Shiraz University of Medical Sciences. Each participant performed 9 tests in 5 min at 3 different temperatures (20°C, 25°C, and 30°C) and 3 lighting conditions (50, 500, and 1000 lux). The participants were asked to select a text randomly. Participants asked to read the text in just 6 min and identify the mistakes. In each step, the number of remaining lines, number of spelling mistakes found, and task completion time were estimated. Results: There was no significant relationship between the temperature and the number of remaining lines, the number of spelling mistakes, and the task completion time (P > 0.05). However, the relationship between different light intensity and the number of remaining lines and number of spelling mistakes was statically significant (P < 0.05). At a lighting of 500, 1000 lux, and a temperature of 25°C, male subjects performed better. Unlike men, women's performance was not affected that much by the light intensity and only declined slightly in the 1000 lux and at 20°C. Conclusions: The results showed that light intensity could be important to create a suitable environment for reducing human error. If the temperature could not increase in an environment due to the nature of a job or economic issues, reducing human errors could achieve by increasing light intensity.

Fatemeh Hosseini, Alireza Khodavandi, Fahimeh Alizadeh
Aim: The aim of this study was to develop combination approach for the treatment of Escherichia coli-producing extended-spectrum β-lactamases (ESBLs) isolated from intensive care unit (ICU)-acquired urinary tract infections (UTIs). Materials and Methods: The observational study was conducted between January 5, 2018- June 5, 2019 to isolate and detect E. coli from UTI patients admitted to ICUs in Shahid Rajaee hospital, Gachsaran, Iran. Morphological, biochemical and molecular methods were conducted to identify E. coli isolates. Phenotypic confirmation of E. coli producing ESBL was performed using ESBL disc diffusion test according to the Clinical and Laboratory Standards Institute (CLSI) guidelines. The combination index assay set-up was based on CLSI guidelines to investigate antibacterial susceptibilities to vancomycin alone and in combination with trimethoprim and interpreted with the fractional inhibitory concentration (FIC) index. Eventually, the expression levels of blaCTX-M-33 gene were determined by real-time quantitative reverse transcription–polymerase chain reaction. Results: A total of 90 ICU-acquired UTIs occurred among 255 patients. The combination index assay results showed that vancomycin/trimethoprim combination would be reduced its minimal inhibitory concentration90 value. The vancomycin/trimethoprim combination revealed partial synergistic and indifferent effects (FIC = 0.52–1.50) in the isolates of E. coli-producing ESBL. The results of gene expression analysis indicated that vancomycin/trimethoprim combination caused downregulation of blaCTX-M-33 gene at negligible levels by 55.56–58.82-fold and stopped drug resistant. Conclusion: Vancomycin/trimethoprim combination may diminish resistance in the E. coli-producing ESBL isolated from ICU-acquired UTI patients.

Alok Kumar, Janine Taitt, Prerna Singh
Aims: In this study, we aim to describe the impact of COVID-19 pandemic on the burden and pattern of hospitalization from the COVID-19-unrelated illnesses among children in Barbados. Materials and Methods: This is a population-based prospective clinical audit. It included children (Age <16 years) admitted for COVID-19-unrelated illnesses to the only tertiary care hospital in this country during the ongoing COVID-19 pandemic. This audit covers the period extending from April to July 2020. The audit data for the corresponding period in 2019 and and 2018, which were also collected prospectively, was used as historical control. Results: There were a total of 178 pediatric medical admissions (PMAs) in this country from April to July 2020. This was a decline of 47.2% (95% confidence interval [CI] = 41.6%, 52.5%) compared to the 336 PMA during the corresponding period in 2019 and 2018. The decline in the number of admissions from asthma phenotypes, respiratory infections, and gastrointestinal infections accounted for 88.0% (95% CI – 78.6%, 94.8%) of the total decline in PMA during the pandemic-related lockdown period when compared with the corresponding period in 2019. The difference in the proportion of children who required transfer to the pediatric intensive care unit during the pandemic and the corresponding period in 2019 and 2018 was statistically not significant (P = 0.8234). Conclusions: A sharp decline in the admissions from asthma phenotypes and those from the respiratory tract and gastrointestinal tract infections resulted in a close to 50% decline in hospitalizations from COVID-19-unrelated illnesses among children in this population.
