Abstract

Introduction: Increasing firefighters’ occupational resilience promotes their safety and safe performance in hazards. Despite its significance, no instrument has so far been developed to assess firefighters’ occupational resilience. The present study, therefore, aimed to design such an instrument.
Material and methods: Firefighter’s occupational resilience indicators were first extracted through a systematic review and a qualitative study to develop the preliminary items. The face and content validity of the items were then examined. The remaining items underwent an exploratory factor analysis (EFA), test-retest reliability, and finally a confirmatory factor analysis (CFA).
Results: After content validity, 49 out of the 94 preliminary items were assessed in terms of construct validity. EFA and rotation revealed that five factors explained 42.477% of the total variance of the questionnaire. The 42 items were categorized into five domains of self-efficacy (20 items), legality (7 items), organizational trust (6 items), self-regulation (5 items), and job satisfaction (4 items). The instrument was finalized with a CFA of the final model and test-retest reliability assessment.
Conclusion: All the personal, organizational, and environmental aspects related to firefighters must be considered for resilience evaluation. This instrument can facilitate firefighters’ resilience assessment. With the outcome of this instrument, firefighters and fire department managers can identify weaknesses, strengths, and assess the effectiveness of interventions to improve firefighters’ occupational resilience.

Abstract

A curcumin-conjugated MgO nanostructure (Cur/MgO NPs) was synthesized, and its composition was verified. XRD and a particle size analyzer were used to determine the average crystalline and particle sizes. Morphological studies were conducted using FE-SEM. UV-Vis was also employed to examine absorption patterns, and FT-IR spectroscopy analyzed the functional groups involved in the reaction. The following protocol evaluated the effectiveness of Cur/MgO NPs in ketamine-treated male BALB/c mice. Group 1 received 0.2 mL of normal saline. Group 2 animals received Ket (25 mg/kg). Group 3 animals received 40 mg/kg Cur and 25 mg/kg Ket. Groups 4–6 received Ket (25 mg/kg) and Cur/MgO N.P.s (10, 20, or 40 mg/kg). Group 7 received 5 mg/kg MgO and Ket (25 mg/kg). Mice were injected ip daily for two weeks. The hippocampal tissue was analyzed for oxidative stress, inflammation, apoptotic markers, and mitochondrial quadruple complex enzymes. The Cur/MgO N.P.s were neuroprotective against the inflammation, apoptosis, and oxidative stress induced by Ket.

Abstract

Water utilities are facing significant challenges, such as supplying more water (due to population growth) with fewer water resources, amid the current scenario of climate change. In this context, urban water systems represent a crucial component of global public infrastructure for water utilities, with municipalities entrusted with the responsibility of managing and enhancing them for both current and future generations. The main challenge arises when these infrastructures inevitably age and deteriorate, significantly increasing water losses. Since it is unrealistic and unnecessary to rehabilitate and/or replace all pipes in an existing water distribution system, this manuscript is focused on identifying the independent key parameters to detect reinforced concrete pipe deterioration. To this end the variables that affect mechanical properties are narrowed down the most significant factors crucial for pipe failure are identified. In this process, reinforced concrete pipe samples were collected to characterize them based on a set of potential key parameters. All potential key parameters were analyzed with the objective of identifying which key parameters were independent. All data were stored in a dataset which was used to generate a predictive model to estimate average concrete strength and pipe condition assessment versus independent key parameters. The predictive model could estimate the average concrete strength with an accuracy of around 90%, and the external porosity was found to be the main factor. On the other hand, it was also possible to estimate a range of porosity values for maintaining the reinforced concrete pipe in optimal conditions.

Abstract
Passive radiative cooling spontaneously emits thermal radiation into the cold universe, providing an environment-friendly solution for cooling. Unlike the mature methods for annual performance evaluation of solar energy harvesting, appropriate long-term radiative cooling performance simulation methods that can be used across different cities in the world are still missing. The main reason is that the spectral distribution of atmospheric radiation varies sensitively with sky status (e.g., cloudy, humid, etc.), while the normalized solar radiation spectrum is relatively stable regardless of weather conditions. Currently reported atmospheric radiation models in radiative cooling field, including the effective sky emissivity model and Modtran model, cannot simultaneously meet the spectral, spatial, and temporal requirements. Herein, we propose an accurate long-term radiative cooling simulation method by developing a novel black-gray (BG) body atmospheric radiation model based on the atmospheric spectral properties and the measured atmospheric radiative power. Experimental validation has been performed in cities with different climate styles and results show superior accuracy than reported methods. The proposed radiative cooling simulation method is well-suited for diverse environmental conditions, encompassing different weather conditions, climate styles, and seasons. It is also applicable for both spectral broadband and selective coolers, particularly for recently proposed selective coolers. To further apply the proposed method, we propose a concept of atmospheric spectral energy databases for the first time and provide a demo case study in Hefei, China, which aims to guide the accurate long-term radiative cooling simulation analysis.

Abstract

Background and Aims
Soil organic carbon (SOC) is the biggest uncertainty when estimating the global C budget. Fine root turnover is the main source of SOC, but it exhibits significant spatio-temporal variation. Therefore, understanding the complex interactions of fine roots is essential for assessing soil carbon dynamics in forest ecosystems.
Methods
Fine root dynamics were investigated in adjacent evergreen pine (TCK) and deciduous oak (TBK) forests. Minirhizotron images were taken over two years to analyze root production, mortality, turnover, and longevity. Sequential coring was used to assess root biomass and morphological characteristics, as well as soil chemical properties at different depths.
Results
Although TCK roots had larger diameters compared to TBK, TCK unexpectedly showed higher turnover rates. Additionally, TCK exhibited a bimodal phenological pattern while TBK exhibited a unimodal pattern. Across different soil depths, TBK had a higher length (SRL) compared to TCK, while root tissue density was similar. Regarding soil depth, TBK had concentrated biomass in shallow soils with significantly higher SRL and faster turnover rates compared to deeper soils, whereas TCK displayed similar values across soil depths. These differences in root characteristics were evident in higher soil carbon in TCK compared to TBK. In TCK, carbon was evenly distributed throughout the soil depth, whereas TBK had more carbon in shallow soils.
Conclusion
These findings emphasize the importance of adopting spatio-temporally comprehensive approaches to evaluate fine root dynamics, providing better insights into the belowground portion of terrestrial biosphere models and forest ecosystem carbon cycling.

Abstract

Background and Aims: Omega 3 polyunsaturated fatty acids (n3 PUFAs) may exert beneficial effects on the immune system of patients with viral infections. This paper aimed to examine the effect of n3 PUFA on severity and symptoms in critically ill patients with COVID 19Methods In a cross-sectional study, 250 COVID-19 patients between the ages of 18 and 65 were enrolled. To gauge dietary omega-3 consumption, a validated 168-item online food frequency questionnaire (FFQ) was used. The severity of COVID-19 was determined using the COVID-19 Treatment Guidelines, and symptoms were assessed using a common questionnaire. Crude and modified analyses were carried out. (Model 1: age, sex, and energy intake; Model 2: Model 1 + physical activity, supplements, corticosteroids, and antiviral drugs; Model 3: Model 2 + body mass index).Results The mean age of participants was 44.06 ± 11.84 years, and 46% of them had severe COVID-19. Patients at the highest tertile of dietary omega-3 intake had lower serum levels of inflammatory biomarkers, including CRP (10.25 ± 13.12 vs. 25.20 ± 24.89 mg/L, p < 0.001) and ESR (14.55 ± 15.02 vs. 29.13 ± 2.26 mm/hr, p < 0.001), than those at the lowest tertile. After controlling for potential confounders, we observed that a higher dietary omega-3 intake was associated with a lower odds of severe COVID-19 (OR: 0.42; 95% CI: 0.22–0.79).Conclusion We found that higher intake of dietary omega-3 was inversely associated with COVID-19 severity and symptoms.

Abstract

Standard Crs reference values (50–70 ml/cmH2O) lack population-specific data and might be influenced by anthropometry. This study aimed to establish practical Crs values, explore the Crs/Predicted Body Weight (PBW) relationship, and develop a predictive model for Crs. A multicenter, cross-sectional study involving mechanically ventilated patients was conducted across Brazil. Patients with hemodynamic instability, chest wall deformities, or intrathoracic limitations were excluded. Data collected included PBW, plateau pressure, Crs, and Driving Pressure (DP). Patients were categorized into three PBW groups (G1 < 59kg, G2 59-68kg, G3 > 68kg) and further stratified by the presence/absence of pulmonary disease. The study included 159 patients with median values of Crs (38.0 ml/cmH2O), DP (9.0 cmH2O), and Crs/PBW (0.65 ml/cmH2O/kg). Statistically significant differences in Crs were observed between G1 vs. G2 (p = 0.03) and G1 vs. G3 (p < 0.01). However, the presence/absence of pulmonary disease did not significantly affect Crs (p = 0.59). The formulated predictive model for Crs yielded an R² of 0.157. Our study indicated that Crs in mechanically ventilated patients with near-normal elastance appears influenced by anthropometric data, particularly height and sex. A Crs/PBW cutoff of 0.6 ml/cmH2O/kg was established. The study also presents a preliminary model for Crs prediction.
Cities as a threshold to Circularity; a Case Study on Urban Fashion and Textile Networks
Authors: Samie Yasaman 
Published: March 2024

Abstract

The Circular Economy (CE) counters linearity by optimising resource consumption, a concept applied in the Fashion and Textile (F&T) industry for decades. However, F&T systems persist as linear. This study identifies two research gaps: the underexplored mesoscopic context linking micro to macro F&T systems and the absence of a theoretical approach to comprehend F&T complexities. It employs a network-based theoretical approach, utilising Actor-Network Theory, lifecycle thinking, and CE concepts to investigate how the city functions as a linking mesoscopic context to enact CE in F&T systems. Conducting a case study in metropolitan Melbourne, Australia, through 19 semi-structured interviews, this study identifies seven key urban F&T networks shaping unwanted textile flows: Production, Consumption, End-of-Consumption, Domestic Reuse, Domestic Recycling, Exports, and Landfill. Recommendations for reshaping these flows and promoting CE include alternative urban F&T networks of Prosumption, Expanded Domestic Reuse, Expanded Domestic Recycling, Shrunk Exports, and Recover. This study concludes emphasising the boundaries of a city, offers a tangible way to harmonise the F&T systems on micro to macro scales and finds the connection between the place and practice pivotal in systemic transition.
A Unique Case of Wilkie Syndrome Reported in a Middle-Aged Female with Posterior Nutcracker Syndrome
Authors: Mirică Roxana Elena , Apan Bogdan 
Published: March 2024

Abstract

Nutcracker and Wilkie syndromes are rarely encountered, often being diagnosed incidentally during imaging investigations for other conditions. In this paper, we present the case of a 36-year-old patient with quasi-permanent symptoms characterized by epigastralgia, loss of appetite, early satiety, left lumbar colic pain, and dysuria. The clinical examination revealed a supple abdomen, sensitivity to palpation in the epigastrium and hypogastrium, frequent urination, and severe protein-caloric malnutrition body mass index (BMI = 15 kg/m2). Laboratory tests indicated a persistent microscopic hematuria without proteinuria and repeated urinary infections. Abdominal-pelvic ultrasound with Doppler showed a dilated left renal vein(LRV) up to 10 mm left of the paraaortic (Nutcracker syndrome) and duodenal obstruction with distension at this level, also confirmed by gastroduodenoscopy (EGD) (Wilkie syndrome). Abdominal-pelvic angioCT results indicated a malformation of the left renal vein dilated by compression in the aorto-mesenteric clamp and communicating with an aberrant left paravertebral and paraspinal network extending to L1 and L5 and a thrombosis of the left ovarian vein. The patient benefited from conservative treatment.

Published: March 2024

Abstract

Background
Osteoarthritis (OA) is a primary cause of disability among the elderly, and its pathogenesis is unclear. This study explores the correlations of different meteorological factors to characteristics and outcomes of knee osteoarthritis (KOA) patients through a 2-year follow-up.
Methods
The study enrolled 70 participants with KOA from Shanghai, China and conducted a follow-up assessment 2 years later. Assessment parameters included knee pain score, bone marrow abnormality (BMA) score, and levels of proinflammatory cytokine interleukin-1β (IL-1β) and IL-6. Additionally, meteorological data on temperature, wind speed, and relative humidity were collected from local meteorological stations. At baseline, meteorological factors were discretized into binary variables using their respective median values. The analysis of the associations between these meteorological factors and pain scores, BMA scores, and proinflammatory cytokines levels were conducted through the Mann-Whitney U test. Longitudinally, the associations between these meteorological factors and the mentioned KOA indicators were determined using multivariate linear regression models.
Results
At baseline, the average age of individuals is 60.6 years old. In the low temperature group individuals had higher WOMAC pain scores (p = 0.022), increased levels of IL-1β (p < 0.001) and IL-6 (p = 0.047) compared to those in the high temperature group. In longitudinal analysis, there were notable associations between temperature fluctuations and alterations in the pain scores (β=-0.916, p < 0.001), IL-1β (β=-0.859, p < 0.001) and IL-6 levels (β=-0.577, p = 0.006).
Conclusion
These findings provide evidence that temperature has a significant impact on the pain and inflammatory levels in patients with KOA. Conversely, wind speed and relative humidity do not exhibit such effects.

Authors: Rezaei Ali , Yazdi Hassan Sharifi , Rakhshandehroo Ehsan , Yaghoobpour Tina , Derakhshandeh Nooshin 
Published: March 2024

Abstract

Background
Dogs may be infected with species of leishmania parasites that are disseminated through the body by blood circulation and invade the internal organs. Therefore, in this study, we attempted to find out the parasite in the blood of dogs in an area where the disease is more identified as the cutaneous type of leishmaniasis. A total of 135 blood samples were taken from dogs (50 Anaemic and 85 normal) and subjected to PCR reaction using ITS-1 and ITS-2 regions of the ribosomal gene.
Results
Totally, seven samples (5.1%) were positive, six were identified as L. tropica and one sample was L. major. This result was interesting because we did not find any case of L. infantum which is always known for visceral infection. In addition, no sign of cutaneous lesions or a significant disease was seen in the animals infected with both species. From 48 dogs suffered from anemia, 2 cases were Leishmania positive. The mean value of hematological parameters in the infected dogs was within the normal range except for a significant reduction in the platelet measures (p < 0.05).
Conclusions
Our data revealed that both Leishmania species, tropica and major, may manifested by viscerotropic leishmaniasis. More investigations are needed to find the conditions that those species decide to select the type of infection. Moreover, our data emphasize the role of asymptomatic dogs to carry the Leishmania parasite.

Abstract
Diarrhoeal diseases and intestinal helminthiasis are major health problems, especially in rural areas with poor hygiene conditions. This study was conducted to determine the relationship between diarrhoeal diseases and intestinal parasitic infections. In November 2017, we conducted a cross-sectional parasitological survey in thirteen (13) localities in the Taabo sub-prefecture which hosts a Health and Demographic Surveillance System. Study participants were asked to provide a stool sample. These samples were examined macroscopically and microscopically for diarrhoea and intestinal parasite infections, respectively. Overall, 690 participants were included in this study. The prevalence of diarrhoeal disease was 15.9% (110/690). In addition, stool analysis by Kato-Katz method revealed prevalence of 15.5% and 3.2% for Ancylostoma spp. and Trichuris trichiura, respectively; 0.1% for Ascaris lumbricoides and Schistosoma mansoni. Of these parasite species, a significant association was observed between cases of diarrhoea and T. trichiura (X2 = 6.443; P = 0.011). This study showed relatively high prevalence of diarrhoeal diseases and hookworm infestation in Taabo sub-prefecture. However, parasitic diseases were found at significantly lower prevalence than in previous studies. These results underscore the need for integrated interventions for effective and efficient control of these diseases to alleviate their burden among vulnerable groups.
