Published: July 2023

Introduction: Firefighters are often placed in situations that require high levels of physical exertion, leading to significant strain on firefighters’ musculoskeletal system, predisposing them to musculoskeletal discomfort (MSD) and/or musculoskeletal injury (MSI). Physical fitness programs are often recommended and justified, in part, to prevent injuries. The aim of this study was to determine the association between physical fitness and musculoskeletal health (MSH) in firefighters.Methods: A total of 308 full-time firefighters took part in the study conducted in Cape Town, South Africa. Physical fitness tests encompassed a non-exercise estimation for cardiorespiratory fitness, grip and leg strength for upper and lower body strength, push-ups and sit-ups for muscular endurance, and sit-and-reach for flexibility. The Nordic Musculoskeletal Questionnaire and Cornell Musculoskeletal Discomfort Questionnaire were used to determine MSIs and MSD, respectively. A p-value &lt;0.05 indicated statistical significance.Results: Every one-unit increase in AbVO2max, push-ups, sit-ups, and sit-and-reach decreased the odds of firefighters reporting MSIs by 5% (p = 0.005), 3% (p = 0.017), 3% (p = 0.006), and 3% (p = 0.034), respectively. Every one repetition increase in push-up capacity increased the odds of firefighters reporting neck, elbow and forearm, wrist and hand, and thigh discomfort by 3% (p = 0.039), 4% (p = 0.031), 5% (p = 0.002), and 5%` (p = 0.007), respectively. Every one repetition increase in sit-up capacity increased the odds of firefighters reporting upper back discomfort and thigh discomfort by 5% (p = 0.045) and 7% (p = 0.013), respectively.Conclusion: Maintenance of physical fitness is likely beneficial in reducing MSIs, which, however, may increase the feeling of MSD in firefighters. In addition, it may be noticed that there is an ideal level of physical fitness that is conducive to the reduction of MSIs and should be studied further.

IntroductionDue to the shortage of land and water resource, optimization of systems for production in commercial greenhouses is essential for sustainable vegetable supply. The performance of lettuce productivity and the economic benefit in greenhouses using a soil-based system (SBS) and a hydroponic production system (HPS) were compared in this study.MethodsExperiments were conducted in two identical greenhouses over two growth cycles (G1 and G2). Three treatments of irrigation volumes (S1, S2, and S3) were evaluated for SBS while three treatments of nutrient solution concentration (H1, H2, and H3) were evaluated for HPS; the optimal levels from each system were then compared.Results and discussionHPS was more sensitive to the effects of environmental temperature than SBS because of higher soil buffer capacity. Compared with SBS, higher yield (more than 134%) and higher water productivity (more than 50%) were observed in HPS. We detected significant increases in ascorbic acid by 28.31% and 16.67% and in soluble sugar by 57.84% and 32.23% during G1 and G2, respectively, compared with SBS. However, nitrate accumulated in HPS-grown lettuce. When the nutrient solution was replaced with fresh water 3 days before harvest, the excess nitrate content of harvested lettuce in HPS was removed. The initial investment and total operating cost in HPS were 21.76 times and 47.09% higher than those in SBS, respectively. Consideration of agronomic, quality, and economic indicators showed an overall optimal performance of the H2 treatment. These findings indicated that, in spite of its higher initial investment and requirement of advanced technology and management, HPS was more profitable than SBS for commercial lettuce production.

BackgroundDengue fever is a rapidly emerging infection worldwide with a high public health burden. Adequate training of healthcare workers is essential to warrant the timely provision of health services to improve the outcome of dengue management.MethodsThis is an analytical cross-sectional study, conducted to assess the knowledge, attitudes and practice (KAP) of healthcare workers regarding dengue from April 2021 to March 2022 in Mazandaran Province, northern Iran. Data was collected using a researcher-made structured questionnaire, prepared as Google Forms, and sent to target groups through social media and email. Data analysis was performed by SPSS 22 software using descriptive and inferential statistics (Chi-square) at a significant level of 5%.ResultsMost of the respondents had heard about dengue (83.8%); media (32.7%) and academic education (25%) were the main sources of information. Respondents had less knowledge associated with dengue symptoms (52%) than prevention and control (69%), transmission (72.2%) and clinical management (81%). Based on the 70% cut-off point, the majority of the participants had a good attitude (81%) and practice (73%). However, only 49.6% of the respondents showed good practice regarding dengue local transmission. A significant difference was observed between participants knowledge on clinical management with occupation; attitude with gender and occupation; and practice with gender (p &lt; 0.05).ConclusionThe results of this study revealed gaps in some dimensions of KAP in healthcare workers, therefore, a greater focus should be placed on future training programs to raise knowledge and attitude leading to sound practice and behavior for adequate management of dengue.

IntroductionDuring the COVID-19 pandemic, sleep problems were highly prevalent. However, few studies assess sleep quality among parents and caregivers with young children. This study aimed to describe the impacts of the COVID-19 pandemic on sleep patterns among parents and caregivers with young children (&lt;6 years) and identify the factors associated with insomnia and sleep efficiency.MethodsAn internet sample of 136 caregivers (age: 35 ± 9.7 y, 70.6% female) were recruited internationally from May 21, 2020 to July 1, 2020. Participants completed the Center for Epidemiological Studies–Depression Scale-10 (CES-D-10), Sleep Hygiene and Practices Scale (SHPS), Coronavirus Impact Scale (CIS), Insomnia Severity Index (ISI), and sleep patterns prior to and during the pandemic. Hierarchical regressions were conducted to examine the factors associated with insomnia and sleep efficiency.ResultsNearly 40% of the caregivers reported household incomes &lt;$10,000. More than half reported clinical levels of depressive symptoms (59.2%) and low sleep efficiency (65.8%). Approximately 90% reported that their sleep-wake routine was altered with delayed bedtime and midpoint, and more naps and nightmares. Almost half (51.5%) were experiencing clinically meaningful insomnia symptoms. Greater insomnia symptom severity was independently associated with lower income, greater depressive symptoms, poor sleep hygiene behaviors, altered sleep-wake routine, and greater COVID-related disruptions in daily life. The predictors associated with poor sleep efficiency during the pandemic were lower income and poor sleep efficiency before the pandemic.DiscussionThe study highlighted the factors associated with insomnia and poor sleep efficiency during the COVID-19 pandemic. Interventions are needed to support caregivers' sleep during global crises.

Published: July 2023

IntroductionIndigenous Wild edible plants (IWEPs) are consumed daily in some form by at least one in seven people worldwide. Many of them are rich in essential nutrients with the potential for dietary and nutrition improvement particularly for poor households. They are, however, often overlooked. This study investigated diversity, consumption frequency, and perceptions of IWEPs and the contribution they make to the food security of communities in Turkana County, northern Kenya. Our findings are aimed at stimulating targeted discussions among stakeholders involved in food security programs on best way to overcome the poverty stigma associated with IWEPs consumption and to promote their utilization for food security, nutritional and dietary improvement, and enhanced community resilience.MethodsApplying a mixed-methods approach, we collected data using 12 gender-disaggregated focus group discussions and a questionnaire applied to a random sample of 360 households.Results and DiscussionParticipants identified 73 IWEPs, of which 24 were consumed in the preceding six months by 48.5% of households. Almost all surveyed households (96%) were classified as severely food insecure, and food insecurity did not differ significantly between households that consumed IWEPs and those that did not. Our results indicate that more IWEPs consumers than non-consumers reported eating foods they had not wanted to consume to cope with food scarcity, as well as having to eat fewer meals than normal. Just over half of the respondents (57.1%) held positive attitudes towards IWEPs, which was positively associated with a higher likelihood of IWEPs consumption. Long distances to harvest sites, lack of knowledge about the plants, their seasonality, and how to cook them appetizingly, coupled with overall unfavorable perceptions, are probable reasons for non-consumption of IWEPs among the survey respondents. In line with other studies cited on wild foods, we conclude that IWEPs have the potential to bridge food and nutritional deficits in food insecure households in the study area, although currently their consumption remains limited. Given this potential, further analysis of IWEPs’ nutritional composition and restoration of wild edible foods to local areas should be given priority, as well as interventions that help to overcome the challenges to their consumption and promote their wider use.

The cytochrome P450 monooxygenases (CYP450) are the largest enzyme family in plant metabolism and widely involved in the biosynthesis of primary and secondary metabolites. Foxtail millet (Setaria italica (L.) P. Beauv) can respond to abiotic stress through a highly complex polygene regulatory network, in which the SiCYP450 family is also involved. Although the CYP450 superfamily has been systematically studied in a few species, the research on the CYP450 superfamily in foxtail millet has not been completed. In this study, three hundred and thirty-one SiCYP450 genes were identified in the foxtail millet genome by bioinformatics methods, which were divided into four groups, including forty-six subgroups. One hundred and sixteen genes were distributed in thirty-three tandem duplicated gene clusters. Chromosome mapping showed that SiCYP450 was distributed on seven chromosomes. In the SiCYP450 family of foxtail millet, 20 conserved motifs were identified. Cis-acting elements in the promoter region of SiCYP450 genes showed that hormone response elements were found in all SiCYP450 genes. Of the three hundred and thirty-one SiCYP450 genes, nine genes were colinear with the Arabidopsis thaliana genes. Two hundred SiCYP450 genes were colinear with the Setaria viridis genes, including two hundred and forty-five gene duplication events. The expression profiles of SiCYP450 genes in different organs and developmental stages showed that SiCYP450 was preferentially expressed in specific tissues, and many tissue-specific genes were identified, such as SiCYP75B6, SiCYP96A7, SiCYP71A55, SiCYP71A61, and SiCYP71A62 in the root, SiCYP78A1 and SiCYP94D9 in leaves, and SiCYP78A6 in the ear. The RT-PCR data showed that SiCYP450 could respond to abiotic stresses, ABA, and herbicides in foxtail millet. Among them, the expression levels of SiCYP709B4, SiCYP71A11, SiCYP71A14, SiCYP78A1, SiCYP94C3, and SiCYP94C4 were significantly increased under the treatment of mesotrione, florasulam, nicosulfuron, fluroxypyr, and sethoxydim, indicating that the same gene might respond to multiple herbicides. The results of this study will help reveal the biological functions of the SiCYP450 family in development regulation and stress response and provide a basis for molecular breeding of foxtail millet.

Published: July 2023

Relevance. The need for functional restoration in young children is a sufficiently common problem in modern pediatric dentistry due to the behaviour characteristics of a child under three years old, which hinder dental treatment. Prefabricated zirconia crowns for children appeared relatively recently and have high aesthetic and functional properties. Purpose. To analyze the application of zirconia crowns for functional rehabilitation and periodontal disease prevention in young children, exemplified by clinical cases.Clinical case description. The study presents a clinical case of functional and aesthetic restoration with zirconia crowns in a child under three years old.Conclusion. Zirconia crowns are a promising alternative to other methods of restoring anterior teeth in a toddler. The clinical case shows that zirconia crowns look natural, fully compensate for the defect, restore the lost function without long-term complications and do not adversely affect the periodontium.

Цель. Изучение частоты колонизации полости носа Staphylococcus aureus у детей с рецидивирующими носовыми кровотечениями неясной этиологии. Материалы и методы. Исследованы 28 детей в возрасте от 4 до 12 лет, страдающих рецидивирующими носовыми кровотечениями (НК) неясной этиологии. Помимо общеклинического исследования, позволившего исключить наличие нарушений гемостаза и патологии сосудистой стенки, произведено бактериологическое исследование передних отделов полости носа. Контрольную группу составили 28 детей, поступивших на плановое хирургическое лечение в лор-отделение, не страдающих носовыми кровотечениями. Результаты. При осмотре полости носа у детей с рецидивирующими НК отмечено более частое присутствие корок и видимой сети сосудов в передних отделах перегородки носа, чем в контрольной группе. При бактериологическом исследовании у детей с рецидивирующими НК у 64,28% обнаружен S. aureus, в то время как в контрольной группе он присутствовал у 17,85% детей. Заключение. Колонизация полости носа S. aureus вызывает вялотекущее воспаление, стимулирующее новообразование патологических сосудов в СОН, что приводит к возникновению НК.
Purpose. To study the incidence of nasal colonization by Staphylococcus aureus in children with recurrent epistaxis of unclear etiology. Materials and methods. The study involved 28 children aged 4 to 12 years suffering from idiopathic recurrent epistaxis. Along with common clinical examination allowing excluding hemostasis disorders and vascular wall pathology, bacteriological examinations of the nasal cavity were performed. The control group consisted of 28 children admitted for surgical treatment in the ENT department, who did not suffer from epistaxis. Results. When examining the nasal cavity in children with recurrent epistaxis, a more frequent presence of crusts and a visible network of vessels in the anterior region of the nasal septum were noted than in the control group. Bacteriological examination of children with recurrent epistaxis revealed S. aureus in 64.28%, while in the control group it was present in 17.85% of children. Conclusion. Colonization of the nasal cavity with S. aureus causes low-grade inflammation stimulating the angiogenesis of pathological vessels in the nasal mucosa, which leads to the development of epistaxis.

Aim: This study evaluates the association between health-promoting lifestyles and diabetes knowledge with glycemic control in adults with type 2 diabetes.
Methods: This cross-sectional study employed convenience sampling and a structured interview questionnaire consisting of the following measures: demographic and clinical characteristics, Health Promotion Lifestyle Profile II, diabetes knowledge questionnaire, and laboratory measurements. Descriptive and inferential statistics were used to analyze the data.
Results: The study included 248 participants recruited from four public hospitals. The results indicated a deficit in several aspects of diabetes knowledge and a suboptimal adoption of health-promoting lifestyles. The findings showed that 81.5% of the sample had non-optimal glycemic control as measured by glycosylated hemoglobin (HbA1c) level. Health-promoting lifestyles predicted optimal glycemic control, while insulin use was a statistically significant predictor for non-optimal glycemic control.
Conclusion: Most participants did not have their diabetes controlled and their diabetes knowledge and health-promoting lifestyles were suboptimal. Health promotion education and strategies to enhance health-promoting lifestyles and diabetes management are essential to patients so that they become confident about managing their diabetes.

Published: July 2023

ABSTRACT

The purpose of this study is to determine the effect of shading and mulching on microclimates in tomato plants. This study used a Randomized Block Design (RBD) method with shade and mulch treatment consisting of 6 levels of treatment namely shade without mulch (NTM), plastic mulch shade (NMP), straw mulch shade (NMJ) and without shade without mulch (TNTM) , without plastic mulch shade (TNMP), without straw mulch shade (TNMJ). Each treatment was repeated three times so that there were 18 experimental units. The parameters observed in this study are plant parameters including plant height, number of branches, age of flowering, number of fruit plants and plant fruit weight. Microclimate observations include measurements of soil moisture, soil temperature, ambient temperature and humidity, wind speed and light absorption. Soil physical and chemical properties observed included soil texture, volume weight, specific gravity, soil pH, available K, porosity, organic matter, total N, field capacity and withering point. The results showed that the use of shade and mulch affected the soil moisture content. Shade can also reduce air temperature and can increase humidity. At the soil temperature the use of shade is very influential because it can reduce soil temperature, while the use of mulch also affects because it can reduce the radiation received and absorbed by the soil so that it can reduce soil temperature. Shade affects the speed of the wind and the absorption of light, where the speed of the wind and the absorption of light that is in the shade is lower than in the shade. Data on growth and production of tomato plants were analyzed using variance and tested further using a BNT advanced level of 5%. The use of shade and mulch has a very significant effect on the plant height observation variable at the age of 52 days after planting, but it does not have a significant effect on the observed variables of the number of branches, flowering age, number of fruits and fruit weight in tomato plants (Lycopersicum esculentum Mill). A good mulch for tomato plant growth is silver black plastic mulch, while a good mulch for tomato plant production is rice straw mulch.
