Resilience level and its relationship with hypochondriasis in nurses working in COVID-19 reference hospitals
Introduction: A new coronavirus, called COVID-19, is an acute respiratory disease, which may arouse many psychological disorders since there is no specialized knowledge about it. The present study aimed to investigate the level of resilience and its relationship with hypochondriasis in nurses working in a COVID-19 reference hospital in south of Iran.
Methods: This cross-sectional study was conducted in 2020, in which 312 nurses participated using the census method. Data collection tools were the Conker-Davidson standard resilience scale (CD-RISC) and the Evans Hypoglycaemia Awareness Questionnaire. Data were analyzed using t-test, ANOVA, Pearson correlation coefficient, and multiple linear regression using SPSS software version 23.
Results: The mean scores of resilience and hypochondriasis were 72.38 ± 7.11 and 49.75 ± 8.13, respectively, indicating the moderate level of these two variables among nurses. Hypochondriasis in 18.91, 61.22, and 1.28% of the nurses was mild, moderate, and severe, respectively. There was a significant negative correlation between resilience and hypochondriasis (r = − 0.214 and P < 0.001). In this regard, control (P < 0.001), positive acceptance of change (P < 0.001), spiritual effects (P = 0.001), trust in individual instincts (P = 0.001), and perception of competence (P = 0.002) were detected as the predictors of nurses’ hypochondriasis.
Conclusion: The nurses had moderate levels of resilience and hypochondriasis. Promoting knowledge about COVID-19and increasing information on how to protect oneself and others against the disease along with supportive packages from their managers are thus recommended
Reducing the environmental impact of surgery on a global scale: systematic review and co-prioritization with healthcare workers in 132 countries
Background
Healthcare cannot achieve net-zero carbon without addressing operating theatres. The aim of this study was to prioritize feasible interventions to reduce the environmental impact of operating theatres.
Methods
This study adopted a four-phase Delphi consensus co-prioritization methodology. In phase 1, a systematic review of published interventions and global consultation of perioperative healthcare professionals were used to longlist interventions. In phase 2, iterative thematic analysis consolidated comparable interventions into a shortlist. In phase 3, the shortlist was co-prioritized based on patient and clinician views on acceptability, feasibility, and safety. In phase 4, ranked lists of interventions were presented by their relevance to high-income countries and low–middle-income countries.
Results
In phase 1, 43 interventions were identified, which had low uptake in practice according to 3042 professionals globally. In phase 2, a shortlist of 15 intervention domains was generated. In phase 3, interventions were deemed acceptable for more than 90 per cent of patients except for reducing general anaesthesia (84 per cent) and re-sterilization of ‘single-use’ consumables (86 per cent). In phase 4, the top three shortlisted interventions for high-income countries were: introducing recycling; reducing use of anaesthetic gases; and appropriate clinical waste processing. In phase 4, the top three shortlisted interventions for low–middle-income countries were: introducing reusable surgical devices; reducing use of consumables; and reducing the use of general anaesthesia.
Conclusion
This is a step toward environmentally sustainable operating environments with actionable interventions applicable to both high– and low–middle–income countries

Evaluation and Comparison of Geostatistical Methods to Generating Digital Management Map of CyanazineVariable Rate Cyanazine Application
In this study evaluation and comparison of various interpolation approaches for estimation un-sampled values of soil Organic Matter Content (OMC) and soil texture is presented. The main objective is to develop a precision method for generation of management maps for variable rate application of herbicide that eventuate to save herbicide application and to reduce adverse impact on the environment. For this purpose after sampling of 42 points on the test field and generation of local and global grid of sample points on a PC, various interpolation methods were applied to estimate soil OMC and texture on un-sampled points by Surfer software. Inverse distance to a power, Kriging, minimum curvature, weighed moving average and radial basis function were used as interpolators. To evaluate the mentioned methods, cross-validation approach and two statistical parameters MAE and MBE were used. The results showed that minimum curvature method with MAE equal to 1.31 has the minimum error than other methods. In this method MAE value for sand, silt and clay was equal to 1.6, 1.18 and 0.59, respectively. In comparison with other methods, this approach had the minimum error. It was demonstrated that minimum curvature method was the best approach to estimate grid point values at un-sampled points. Finally after selection of appropriate method and using considered manufacturer recommendations of herbicide application based on OMC and soil texture, a digital management map of Cyanazine variable rate application in a corn field was generated. Based on this map and considering the herbicide uniform application in the farm as 1.7, 2.9 and 4 Lha-1, herbicide application rate compared with 1.8 Lha-1, decreases 39% and increases 4 and 50% respectively. This means that if the entire field is sprayed with the uniform rate of 1.7 Lha-1, Compared with1.8 Lha-1 which is obtained using management map, herbicide application will be saved 39 %. Similarly, if herbicide is applied 2.9 and 4 Lha-1 uniformly, compared to the amount 1.8 Lha-1, 4 and 50% of herbicide application will increase respectively

Responsiveness level and its effect on services quality from the viewpoints of the older adults hospitalized during COVID-19 pandemic
BACKGROUND: Aging is a sensitive period of life. Attention to the needs of this stage is considered a social necessity. This study is conducted to investigate the responsiveness level and its effect on service quality from the hospitalized older adults’ viewpoints during the COVID-19 pandemic in the south of Iran. METHODS: It was a cross-sectional descriptive-analytic study that was conducted on 386 old patients. The study instrument was a standard questionnaire that includes three sections of demographic information, World Health Organization Responsiveness, and SERVQUAL. Data were analyzed applying descriptive and inferential statistics the same as Independent T-test, ANOVA, Pearson correlation, and multiple linear regression. RESULTS: The mean levels of responsiveness and service quality were 90.72 ± 9.38 (from 160) and 68.01 ± 8.51 (from 110) respectively. This indicates the average level of these variables from the old patients’ viewpoints. There was a significant positive correlation between responsiveness and service quality (r = 0.585). According to the results of multiple linear regression, the dimensions of communication, dignity, prompt attention, primary facilities, social support, information confidentiality, right to choose, and autonomy were identified as the predictors of service quality. CONCLUSION: The average level of responsiveness and service quality perceived from the old patients’ viewpoints during the COVID-19 pandemic can be considered a necessity for supportive planning among the older adults. Meanwhile, according to the impacts of responsiveness on service quality, educational programs are recommended to promote the level of healthcare providers’ responsiveness
Effect of General Anesthesia with Thiopental Sodium and Propofol on the 1- and 5 Minute Apgar Newborns by Cesarean
Background: The Apgar score of newborn babies is a determining factor involved with mortality of newborns after birth. Regarding the disagreement on advantages and possible disadvantages of propofol and thiopental in the available references, the study was triggered with the aim of analyzing effects of two mentioned drugs on babies’ Apgar score.
Methods: In this double-blind clinical trial, a total of 100 healthy women who volunteered to undertake cesarean operation were selected and then divided randomly into two equal groups using statistical blocking. One group was treated by propofol while other one was treated by thiopental. The prescribed drugs for both groups were identical. Babies’ Apgar score 1 and 5 minutes after birth and recovery period and some of the critical maternal parameters after operation were recorded. The obtained data were analyzed by SPSS 19 software.
Results: Apgar score I minute 1 (p=0.317) and Apgar score in minute 5 (p=1.00) for propofol group were not different meaningfully. The groups had significant differences in the indices such as first systolic (P=0.00) and diastolic (P=0.00) pressure in recovery, last diastolic pressure in recovery (P=0.001) and duration of postoperative recovery (P=0.001). Statistical analysis of nausea and vomit in both groups showed that they are lower in propofol group rather than the thiopental group (p=0.000).
Conclusion: Propofol and thiopental did not differ significantly in Apgar score, but it seems that propofol can be a better option to induce anesthesia for an elective cesarean operation
The Incidence of Co-occurrence of Chlamydial Cervicitis with Bacterial Vaginosis
Background and Objectives: Bacterial vaginosis is caused by an imbalance in normal vaginal bacterial flora mainly caused by the introduction of pathogenic bacteria. Failure to properly treat this condition can not only induce abortion but also increase the chance of acquiring other serious infections such as AIDS, gonorrhea and chlamydiosis. Chlamydia trchomatis is one of the causative agents of cervicitis of which 70% is totally asymptomatic. Untreated cases can lead to salpengititis, pelvic inflammatory diseases, infertility, pelvic area pains and other complications. The purpose of this study was to determine the co-occurrence of these two conditions.Methods: A total of 137 patients were examined for both Chlamydial cervicitis and for bacterial vaginosis. Gram stain was used to detect bacterial vaginosis and anti-chlamydial antibodies were titered by microimmunofluoresence (MIF) assay. Results: According to the MIF results, 10 patients(7.3%) had elevated anti-chlamydial IgG and 3 patients (2.2%) showed high IgM titers. Gardnerella vaginalis was detected in 6 patients(4.7%) as the causative agent of vaginosis. There were 3 cases of co-occurrence of chlamydial cervicitis and bacterial vaginosis (30%). Conclusion: Due to the fact that bacterial vaginosis can provide the pre-disposing conditions for cervicitis and its chronicity and the similarity of the cilinical singns of these two conditions, Infections with Chlamydia are often overlooked. It therefore seems necessary to check any patient with bacterial vaginosis for chlamydial co-infection
5-Fluorouracil encapsulated chitosan-cellulose fiber bionanocomposites: synthesis, characterization and in vitro analysis towards colorectal cancer cells
Cellulose and chitosan with remarkable biocompatibility and sophisticated physiochemical characteristics can be a new dawn to the advanced drug nano-carriers in cancer treatment. This study aims to synthesize layer-by-layer bionanocomposites from chitosan and rice straw cellulose encapsulated 5-Fluorouracil (CS-CF/5FU BNCs) using the ionic gelation method and the sodium tripolyphosphate (TPP) cross-linker. Data from X-ray and Fourier-transform infrared spectroscopy showed successful preparation of CS-CF/5FU BNCs. Based on images of scanning electron mi-croscopy, 48.73 ± 1.52 nm was estimated for an average size of the bionanocomposites as spherical chitosan nanoparticles mostly coated rod-shaped cellulose reinforcement. 5-Fluorouracil indicated an increase in thermal stability after its encapsulation in the bionanocomposites. The drug encapsulation efficiency was found to be 86 ± 2.75%. CS-CF/5FU BNCs triggered higher drug release in a media simulating the colorectal fluid with pH 7.4 (76.82 ± 1.29%) than the gastric fluid with pH 1.2 (42.37 ± 0.43%). In in vitro cytotoxicity assays, cellulose fibers, chitosan nanoparticles and the bionanocomposites indicated biocompatibility towards CCD112 normal cells. Most promisingly, CS-CF/5FU BNCs at 250 µg/mL concentration eliminated 56.42 ± 0.41% of HCT116 cancer cells and only 8.16 ± 2.11% of CCD112 normal cells. Therefore, this study demonstrates that CS-CF/5FU BNCs can be considered as an eco-friendly and innovative nanodrug candidate for potential colorectal cancer treatment
Anticancer activity of 5-fluorouracil-loaded nanoemulsions containing fe3o4/au core-shell nanoparticles
Nanoemulsions (NEs) as multi-compartmentalized systems are extensively considered as versatile drug delivery systems, due to their multifunctional and tuneable physicochemical properties. Here, water-in-oil-in-water (WOW) NEs were formulated using Juglans regia-based Fe3O4/Au-core-shell nanoparticles to encapsulate 5-Fluorouracil (5-FU) for potential colorectal cancer treatment. Response surface methodology, FTIR, TGA, TEM, DLS, VSM, UV-vis spectroscopy, and viscosity measurements were used to characterize the fabricated samples. The analysis confirmed the successful synthesis of Au, Fe3O4, and Fe3O4/Au core-shell nanoparticles with the Juglans regia (J. regia) extract as a green stabilizer and also reducing agent. The NE displayed a spherical-shape and TEM size of~30 nm. It also exhibited good colloidal stability and multifunctional features related to its components. TGA data indicated that 5-FU increased thermal stability after its loading into the nanoemulsion as a drug carrier. 5-FU release from the NE carrier presented a time-delayed behavior and higher release dosage in media at pH 4 compared to pH 7 within 48 h. When tested against colorectal-derived cell lines, 0.78 µg/mL of 5-FU-loaded Fe3O4/Au core-shell NEs showed potent anticancer activity against HCT116 cancerous cells, while exhibiting low toxicity towards CCD112 normal cells. In conclusion, the synthesized 5-FU-loaded NEs can be potently used as an anticancer drug carrier model, owing to its nano-scale size and other functionalities, which should be further studied
Green synthesis of Fe3O4 nanoparticles for hyperthermia, magnetic resonance imaging and 5-fluorouracil carrier in potential colorectal cancer treatment
Magnetite nanoparticles (Fe3O4 NPs) have received considerable attention in various biomedical applications due to their fascinating properties and multiple functionalities. In this multidisciplinary study, Fe3O4 NPs were produced by an inexpensive co-precipitation technique and using four different weight percentages of Punica granatum fruit peel extract as a green stabilizer. From the image of transmission electron microscopy, the NPs showed spherical shapes with an average size of 14.38 nm. Results of UV–VIS spectroscopy and bandgap indicated successful preparation of the Fe3O4 NPs stabilized with the extract. Adding the stabilizer concentration improved the particle zeta potential from −29.24 to −35.62 mV. Thermoresponsive performance of the Fe3O4 nanofluids with the green extract could render a remarkable heating capability under the hyperthermia condition. Magnetic resonance imaging (MRI) analysis presented that the samples possessed acceptable MRI signals. An anticancer drug 5-fluorouracil was successfully loaded onto the Fe3O4 NPs containing 2 weight percentage of the extract, which indicated a maximum release of 79% in a media with pH 7.4. In cytotoxicity assays, the drug-loaded Fe3O4 NPs at 15.62 and 31.25 µg.ml−1 concentration eliminated 29% and 35% of HCT116 colorectal cancer cells, respectively. This study, therefore, introduced that the green-synthesized Fe3O4 NPs can be a promising candidate for magnetic hyperthermia therapy, MRI nanoagents and drug delivery in colorectal cancer
