The Role of Dosage and Family Profiles in a Child Welfare Home Visiting Program

Abstract Background Among the different modalities of family support, home visiting programs have proved to be one of the most effective secondary prevention models for families involved in child welfare services. Despite the promising outcomes and the extensive available literature, further research is needed to investigate target population characteristics and implementation factors that may explain the heterogeneity in the outcomes of these programs for families receiving child welfare services. Objective This longitudinal study explored the role of dosage and family characteristics related to the effectiveness of the Family Intervention Program (FIP), which is a home-based Spanish child welfare service for supporting families at psychosocial risk. Method To this end, a quasi-experimental design was followed, including a time-series evaluation of the 289 families receiving the FIP. In order to examine the impact of the FIP, the evolution of child well-being (CWB) was evaluated with Child Well-Being Scales every 6 months. Results The results showed that the highest average CWB score was observed after 39 months of intervention, observing no improvements in CWB from that point. Similarly, the results showed that the FIP was more effective for single parent families at higher socioeconomic levels. Conclusions This article provides new knowledge for the understanding of home visiting programs success, concluding that the programs are not equally effective for all family profiles, and that it is necessary to adjust each program to the specific characteristics of the target population.

Exploring Diversity of Hispanic Health Outcomes Through Prism of Environmental Justice

In environmental economics studies US Hispanics are frequently depicted as one large homogeneous group, despite diversity in their countries’ cultural traditions, genetic background and socioeconomic status (SES). This study aimed to compare Florida’s very diverse Hispanic population of Caribbean, Mexican, Central, and South American ancestry.Twelve independent variables were selected from environmental pollution, geospatial challenges, and SES categories. Dependent variables included the relative prevalence of three major chronic diseases: asthma, diabetes, and heart disease. Analysis of pairs correlations was supplemented by multi-variable linear regression. Majority-Hispanic areas have higher than average pollution, diabetes, proximity to disadvantaged neighborhoods, and lower SES. Despite lower pollution than in urban areas, Florida’s inland rural areas had higher rates of all major diseases and lower life expectancies. Cuban and Puerto Rican populations of Miami and Orlando metro areas, respectively, have less favorable SES outcomes and higher diabetes. Columbian and Venezuelan communities have significantly higher education levels than other Hispanic cohorts, and they have the best relative outcome among US Hispanics in SES and health, although still lagging US averages. African-American community in Miami-Dade County was by far the most disadvantaged, with significantly lower SES and health outcomes than any other group in the study, including the nearby Cuban-majority community. Our results confirmed the view that Hispanics are environmentally disadvantaged in Florida, with worse outcomes than the US and Florida average in health and economic factors. Furthermore, the study highlighted significant differentiation of SES and health outcomes among various regional Hispanic cohorts.

Comparison between Liquid and Tablet Formulations in the Treatment of Congenital Hypothyroidism up to 3 Years of Age: The First Italian Study

Background/Objectives: Levothyroxine (L-T4) is available for use in congenital hypothyroidism (CH) in three formulations: tablets, drops, and oral solution. This study aims to compare the efficacy and safety of all three L-T4 formulations. Methods: We enrolled 63 children born between January 2019 and April 2023 in the Emilia-Romagna Region (Italy) and diagnosed with CH by newborn screening. They were divided according to the L-T4 formulation used: drops (Group D), oral solution (Group S), and tablets (Group T). Clinical and laboratory data were collected up to 3 years after the start of replacement therapy. Results: Serum-free thyroxine (sFT4) and thyroid stimulating hormone (sTSH) normalization occurred within the first month of treatment in most patients of all groups. No negative effects on growth and cognitive development were observed. At 7–15 days we found higher median sTSH levels (p = 0.031) and a greater percentage of patients with sTSH > 5 µU/mL (p = 0.011) in Group S than in Group T, but comparable sFT4 levels. At 12 months, a greater percentage of patients of Group D showed sFT4 values below the normal range than Group S (p = 0.011) and Group T (p = 0.038); Conclusions: Overall, our study reported an equal efficacy of the L-T4 oral solution compared to drops and tablets in CH treatment. A larger series of patients and a long-term follow-up are needed.

SARS-CoV2 pneumonia patients admitted to the ICU: Analysis according to clinical and biological parameters and the extent of lung parenchymal lesions on chest CT scan, a monocentric observational study

Background CT-scan and inflammatory and coagulation biomarkers could help in prognostication of COVID-19 in patients on ICU admission. Objective The objectives of this study were to measure the prognostic value of the extent of lung parenchymal lesions on computed tomography (CT) and of several coagulation and inflammatory biomarkers, and to explore the characteristics of the patients depending on the extent of lung parenchymal lesions. Design Retrospective monocentric observational study achieved on a dataset collected prospectively. Setting Medical ICU of the university hospital of Clermont-Ferrand, France. Patients All consecutive adult patients aged ≥18 years admitted between 20 March, 2020 and 31 August, 2021 for COVID-19 pneumonia. Interventions Characteristics at baseline and during ICU stay, and outcomes at day 60 were recorded. The extent of lung parenchyma lesions observed on the chest CT performed on admission was established by artificial intelligence software. Measurements Several clinical characteristics and laboratory features were collected on admission including plasma interleukin-6, HLA-DR monocytic–expression rate (mHLA-DR), and the extent of lung parenchymal lesions. Factors associated with day-60 mortality were investigated by uni- and multivariate survival analyses. Results 270 patients were included. Inflammation biomarkers including the levels of neutrophils, CRP, ferritin and Il10 were the indices the most associated with the severity of the extent of the lung lesions. Patients with more extensive lung parenchymal lesions (≥ 75%) on admission had higher CRP serum levels. The extent of lung parenchymal lesions was associated with a decrease in the PaO2/FiO2 ratio(p<0.01), fewer ventilatory-free days (p = 0.03), and a higher death rate at day 60(p = 0.01). Extent of the lesion of more than 75% was independently associated with day-60 mortality (aHR = 1.72[1.06; 2.78], p = 0.03). The prediction of death at day 60 was improved when considering simultaneously biological and radiological markers obtained on ICU admission (AUC = 0.78). Conclusions The extent of lung parenchyma lesions on CT was associated with inflammation, and the combination of coagulation and inflammatory biomarkers and the extent of the lesions predicted the poorest outcomes.

Comparative Studies of Some Biochemical and Toxicological Investigations of Chromolaena odorata and Ipomoea involucrata from Lagos Suburb in Nigeria

The search for plants and plants products of medicinal potentials cannot be underestimated. Hence this study sought to investigate some parameters of medicinal importance.The phytochemical constituents, proximate and mineral composition, anti-nutrient contents, and acute toxicity of Chromolaena odorata and Ipomoea involucrata were analyzed using standard analytical methods. Phytochemical screening revealed the presence of reducing sugars, flavonoids, saponins, and alkaloids in both plants. Notably, Ipomoea involucrate exhibited higher saponin levels, suggesting potential unique medicinal properties. Proximate and mineral composition analysis indicated that both plants have low moisture content, which helps in preserving the active compounds by minimizing chemical degradation. Additionally, the plants were found to be rich in crude fiber, protein, and nutritionally valuable elements. Anti-nutrient assessments showed that Chromolaena odorata had the lowest cyanide (5.45mg/100 g) and phytate (0.23mg/100 g) levels, while Ipomoea involucrate had the lowest oxalate content (0.40 mg/100 g). Furthermore, no mortality was observed in tested animals following oral treatment with 2000 mg/kg body weight, indicating a high margin of safety. This study highlights that both Chromolaena odorata and Ipomoea involucrate possess beneficial phytochemical and nutritional profiles. The low moisture content in these plants contributes to the stability of their active compounds, enhancing their potential medicinal value. Ipomoea involucrata stands out for its higher saponin content, which may offer distinctive therapeutic benefits. The minimal presence of anti-nutrients andless lethal effectsfurther support their safety and efficacy as medicinal plants. The findings in this study however underscore the therapeutic potential of these plants and their suitability for use in drug development and their application in therapeutic products.

Association of Gene Polymorphisms and Serum Levels of ALAS1 with the Risk of Anti‐Tuberculosis Drug‐Induced Liver Injury

AbstractThe accumulation of protoporphyrin IX in the liver caused by isoniazid and rifampicin through the disorder of heme biosynthesis was considered an important mechanism of anti‐tuberculosis drug‐induced liver injury (ATLI). Alanine synthase 1 (ALAS1) is a rate‐limiting enzyme in the process of heme synthesis. This study aimed to investigate the association between ALAS1 gene polymorphism, serum ALAS1 level, and the risk of ATLI. This study was a case‐control study including 58 ATLI cases and 192 controls. Four single nucleotide polymorphisms (SNPs) of the ALAS1 gene were selected for genotyping and serum ALAS1 concentrations were detected using ELISA kits. There was no significant difference in the genotype distribution of four SNPs between the ATLI cases and the controls under different genetic models. Patients carrying the GG genotype of SNP rs352163 in controls had higher baseline ALAS1 levels than those in ATLI cases (243.6 vs 290.2 ng/L, P = .034), and patients with baseline ALAS1 < 337.85 ng/L had a higher risk of ATLI than those with ALAS1 ≥ 337.85 ng/L (HR = 2.679, 95% CI: 1.360‐5.278, P = .004). Our findings indicated that the serum ALAS1 concentrations in the ATLI cases were lower than those in the controls, and the lower baseline ALAS1 levels can be associated with higher ATLI risk.

Perceived stress and burnout syndrome in chiropractic students at a South African university during the COVID-19 pandemic: A cross-sectional study.

Higher stress levels may be associated with decreased academic success and physical and psychological well-being in chiropractic students. This study aimed to determine the perceived stress and burnout of chiropractic students at the University of Johannesburg during the COVID-19 pandemic. This was a quantitative, exploratory study utilizing a self-administered online questionnaire distributed to chiropractic students (n = 246) at the university. The questionnaire consisted of 3 main components: demographics, the Perceived Stress Scale (PSS-10), and the Maslach Burnout Inventory-Student Survey (MBI-SS). Data were analyzed utilizing exploratory factor analysis, Cronbach alpha for reliabilities, and descriptive statistics for mean scores being interpreted using subscales pertaining to the 2 survey tools. The response rate was 63.82% (n = 157) with the PSS-10 indicating participants obtained a total mean score of 25.08 (average stress). For the MBI-SS categories, participants scored 18.96 out of 30 for exhaustion, 10.31 out of 30 for cynicism, and 22.46 out of 36 for professional efficiency; higher scores of exhaustion and cynicism and lower scores of professional efficiency are indicative of higher degrees of burnout. Statistically significant differences for both tools were noted in relation to age and academic year with higher values indicated with increased age and progression in the program. The results indicate that chiropractic students experienced moderate levels of stress but higher burnout than other health sciences student populations when compared to current literature. Age and progression in the program appear to have a negative influence on both these factors.

Association between Higher Expression of Vav1 in Hepatocellular Carcinoma and Unfavourable Clinicopathological Features and Prognosis

Objective: The aim was to investigate the potential relationship between Vav1 protein and prognosis in patients with hepatocellular carcinoma (HCC). Methods: Samples were collected from 96 patients with HCC. For each patient, cancerous tissue and adjacent non-cancerous tissue were obtained. The Vav1 expression levels in these tissues were determined using immunohistochemistry. Chi-square and Fisher's exact tests were used to analyse the associations between Vav1 expression and clinicopathological characteristics. Kaplan– Meier analysis was used to assess the relationship between Vav1 expression and 5-year overall survival (OS). Results: The expression level of Vav1 protein in primary tumour samples (64.46%; 59/96) was higher (33.33%; 32/96; P<0.001). Moreover, the high expression rate of Vav1 was correlated with tumour differentiation, TNM stage, and tumour recurrence (P<0.05). Univariate and multivariate Cox analysis further demonstrated that tumour differentiation, TNM stage, vascular invasion, tumour recurrence and Vav1 expression were independent prognostic factors for 5-year OS. Notably, follow-up analysis determined that patients with HCC with higher Vav1 expression levels have lower survival rates (P<0.05). Conclusion: Vav1 may serve as a promising molecular prognostic biomarker for patients diagnosed with HCC.

Pericentriolar material 1 promotes intestinal inflammation in ulcerative colitis by activating NLRP3/gasdermin D‐mediated macrophage pyroptosis

AbstractExcessive proinflammatory cytokine release induced by pyroptosis plays a vital role in intestinal mucosal inflammation in ulcerative colitis (UC). Several pyroptosis‐related factors are regulated by the centrosome. Pericentriolar material 1 (PCM1) is a primary component of centriolar satellites that is present as cytoplasmic granules around the centrosome. Our previous study revealed that PCM1 was highly expressed in UC patients, but the role of PCM1 in UC remains unknown. This study aimed to elucidate the role of PCM1 in the development of UC, especially the mechanism in pyroptosis process of UC. Clinical mucosal sample and dextran sulfate sodium (DSS)‐induced colitis mouse were used to reveal the association between PCM1 and intestinal inflammation. Intestinal epithelial cell‐specific PCM1‐knockout mice were constructed to determine the role of PCM1 in colitis. Finally, PCM1 RNA interference and overexpression assays in THP1 cells were employed to study the molecular mechanisms of PCM1 in inflammatory responses and pyroptosis. We found that PCM1 expression was upregulated in the colonic mucosa of UC patients and positively correlated with inflammatory indicators. PCM1 expression was elevated in DSS‐induced colitis mice and was reduced after methylprednisolone treatment. In the DSS colitis model, intestinal‐specific PCM1‐knockout mice exhibited milder intestinal inflammation and lower pyroptosis levels than wild‐type mice. In cell level, PCM1 exerted a proinflammatory effect by activating the NLRP3 inflammasome and triggering subsequent gasdermin D‐mediated pyroptosis to release IL‐1β and IL‐18. In conclusion, PCM1 mediates activation of the NLRP3 inflammasome and gasdermin D‐dependent pyroptosis, ultimately accelerating intestinal inflammation in UC. These findings revealed a previously unknown role of PCM1 in initiating intestinal mucosal inflammation and pyroptosis in UC, and this factor is expected to be a regulator in the complex inflammatory network of UC.

Drying–Wetting Correlation Analysis of Chloride Transport Behavior and Mechanism in Calcium Sulphoaluminate Cement Concrete

In response to rising CO2 emissions in the cement industry and the growing demand for durable offshore engineering materials, calcium sulphoaluminate (CSA) cement concrete, known for its lower carbon footprint and enhanced corrosion resistance compared to Ordinary Portland Cement (OPC), is increasingly important. However, the chloride transport behavior of CSA concrete in both laboratory and marine environments remains underexplored and controversial. Accordingly, the chloride ion transport behaviors and mechanisms of CSA concrete in laboratory-accelerated drying-wetting cyclic environments using NaCl solution and seawater, as well as in marine tidal environments, were characterized using the rapid chloride test (RCT), X-ray diffraction (XRD), mercury infiltration porosimetry (MIP), and thermogravimetric analysis (TGA). The results reveal that CSA concrete accumulates more chloride ions in NaCl solution than in seawater, with concentrations 2–3.5 times higher at the same water–cement ratio. Microscopic analysis indicates that calcium and sulfate ions present in seawater facilitate the regeneration of ettringite, thereby increasing the density of the surface pore structure. The hydration and repair mechanisms of CSA concrete under laboratory conditions closely resemble those in marine tidal conditions when exposed to seawater. Additionally, this study found that lower chloride ion concentrations and pH levels inhibit the formation of Friedel’s salt. Therefore, laboratory experiments with seawater can effectively simulate CSA concrete’s chloride transport properties in marine tidal environments, whereas NaCl solution does not accurately reflect actual marine conditions.

Evaluation of serum irisin level and severity of erectile dysfunction in diabetic males: a cross sectional prospective study

BackgroundIrisin is an exercise-induced myokine that alleviates endothelial dysfunction and reduces insulin resistance in type 2 diabetes mellitus (T2DM). The current study aimed to assess the serum level of irisin in T2DM men with erectile dysfunction (ED) compared to T2DM patients with normal erectile function and healthy controls, as well as investigate the association between serum irisin level and the severity of ED in T2DM patients.Patients and methodsA cross-sectional study was conducted on 90 males, divided into three groups: 32 T2DM patients with ED, 24 T2DM patients without ED, and 34 healthy controls. Socio-demographic characteristics and scores of the validated Arabic version of the international Index of Erectile Function-5 (ArIIEF-5), Generalized Anxiety Disorder-7 (GAD-7) and Patient Health Questionnaire-9 (PHQ-9) were obtained. Furthermore, routine laboratory tests employed for diabetes monitoring and serum levels of total testosterone and irisin were assessed within these groups.ResultsT2DM men with ED had significantly lower serum levels of irisin and testosterone, as well as a lower ArIIEF-5 score, but their GAD-7 and PHQ-9 scores were significantly higher than those without ED or controls (p < 0.001). Among T2DM men, serum irisin levels positively associated with ArIIEF-5 scores and serum testosterone (r = 0.413, p = 0.002; r = 0.936, p < 0.001, respectively) but negatively associated with glycosylated hemoglobin levels (r = -0.377, p = 0.004). Multivariate regression analysis to predict ED in T2DM patients found that GAD-7 score was the only most significant predictor for ED (ꞵ = − 1.176, standard error = 0.062, p < 0.001).ConclusionThe current study had demonstrated that irisin positively correlated with the ArIIEF-5 and serum testosterone but negatively correlated with HbA1c in T2DM men. Nevertheless, further validation of these findings is necessary through cohort studies.

A Medicago truncatula HD-ZIP gene MtHB2 is involved in modulation of root development by regulating auxin response

HD-Zip proteins are plant-specific transcription factors known for their diverse functions in regulating plant growth, development, and responses to environmental stresses. Among the Medicago truncatula HD-Zip II genes, MtHB2 has been previously linked to abiotic stress responses. In this study, we conducted a functional characterization of MtHB2 in the regulation of root growth and development. Upon auxin stimulation, expression of MtHB2 was promptly up-regulated. Overexpression of MtHB2 in Arabidopsis thaliana led to reduced primary root growth and inhibited lateral root formation. Interestingly, the transgenic plants expressing MtHB2 exhibited differential responses to three types of auxins (IAA, NAA, and 2,4-D) in terms of root growth and development compared to the wild-type plants. Specifically, primary root growth was less affected, and lateral root formation was enhanced in the transgenic plants when exposed to auxins. This differential response suggests a potential role for MtHB2 in modulating auxin transport and accumulation, as evidenced by the reduced sensitivity of the transgenic plants to the auxin transport inhibitor NPA and lower expression levels of auxin-related reporters such as PIN-FORMED (PIN1)::PIN1-GFP, PIN3::PIN3-GFP, PIN7::PIN7-GFP, and DR5::GFP compared to wild-type plants. Additionally, microarray analysis of the root tissues revealed down-regulation of several auxin-responsive genes in transgenic seedlings compared to wild-type plants. These findings collectively indicate that MtHB2 plays a critical regulatory role in root growth and development by modulating auxin accumulation and response in the roots.

Impact of peer-to-peer online experience on cultural tourism marketing

Peer-to-peer (P2P) online experience offers low-cost immersive cultural experiences, but enterprises fear that it will negatively affect local tourism marketing. This study proposes a sequential mediation model to explore how P2P online experience stimulates travel intentions and attraction recommendations. We find that P2P online experience increases cultural presence, which in turn leads to higher situational empathy. This increased empathy then contributes to predicted tourism experience, which ultimately shapes behavioral intentions toward travel and attraction recommendations. Furthermore, the study finds that the impact of P2P online experience on behavioral intentions is stronger for consumers with lower cultural cognitive levels of tourist attractions. Our findings demonstrate the importance of P2P online experience on cultural presence and situational empathy in shaping travel behavior.

Clinical Comparison of Stain Removal Efficacy between Glycine Powder Air Polishing System and Ultrasonic Scaling in Removing Dental Plaque and Stains: A Split-mouth Randomized Clinical Trial

Abstract Introduction: Glycine powder air polishing (GPAP) has emerged as a less invasive option for periodontal maintenance therapy. This study aims at comparing the efficacy of GPAP in removing plaque and stains as compared to conventional ultrasonic scaling (USS). Materials and Methods: The present split-mouth randomised clinical trial recruited 20 adults with healthy gingiva or mild gingivitis. Removal of plaque and stains was performed by USS in one maxillary quadrant and by GPAP in the other. Clinical parameters assessed included stain scores by Lobene Stain Index, plaque level by Silness-Loe plaque Index, and pain scores using the Visual Analog Scale. The assessments were performed before and after the treatment and at a 15-day follow-up visit. Results: Significantly lower (P &lt; 0.05) levels of plaque and stains were achieved by both interventions as compared to those before the treatment. While immediate postoperative plaque levels were significantly (P &lt; 0.05) lower following USS, the difference failed to reach statistical significance (P &gt; 0.05) 1 week after the treatment. On the contrary, the stain scores were significantly lower after treatment and at the 7th-day follow-up after GPAP as compared to USS. A significantly greater number of patients (P &lt; 0.05) reported pain to be absent or only mild following GPAP, while those treated with USS experienced pain of severe intensity. Conclusion: Both GPAP and USS are effective in stain and plaque removal. However, GPAP achieved superior stain removal outcomes and was associated with significantly lower pain scores, suggesting it was more comfortable for patients compared to USS.

The potential benefit of artificial intelligence regarding clinical decision-making in the treatment of wrist trauma patients

PurposeThe implementation of artificial intelligence (AI) in health care is gaining popularity. Many publications describe powerful AI-enabled algorithms. Yet there’s only scarce evidence for measurable value in terms of patient outcomes, clinical decision-making or socio-economic impact. Our aim was to investigate the significance of AI in the emergency treatment of wrist trauma patients.MethodTwo groups of physicians were confronted with twenty realistic cases of wrist trauma patients and had to find the correct diagnosis and provide a treatment recommendation. One group was assisted by an AI-enabled application which detects and localizes distal radius fractures (DRF) with near-to-perfect precision while the other group had no help. Primary outcome measurement was diagnostic accuracy. Secondary outcome measurements were required time, number of added CT scans and senior consultations, correctness of the treatment, subjective and objective stress levels.ResultsThe AI-supported group was able to make a diagnosis without support (no additional CT, no senior consultation) in significantly more of the cases than the control group (75% vs. 52%, p = 0.003). The AI-enhanced group detected DRF with superior sensitivity (1.00 vs. 0.96, p = 0.06) and specificity (0.99 vs. 0.93, p = 0.17), used significantly less additional CT scans to reach the correct diagnosis (14% vs. 28%, p = 0.02) and was subjectively significantly less stressed (p = 0.05).ConclusionThe results indicate that physicians can diagnose wrist trauma more accurately and faster when aided by an AI-tool that lessens the need for extra diagnostic procedures. The AI-tool also seems to lower physicians' stress levels while examining cases. We anticipate that these benefits will be amplified in larger studies as skepticism towards the new technology diminishes.

Evaluation of Maternal Ischemia-Modified Albumin Levels during Pregnancy and Their Effect on Fetal Birth Weight

Background and Objectives: The purpose of this study is to evaluate the impact of maternal ischemia-modified albumin (IMA) levels on pregnancy-related complications, fetal growth, and development over time. Materials and Methods: The prospective longitudinal and single-center study included 43 pregnant women ages 18 to 43. Routine pregnancy follow-up began at the first antenatal examination for all pregnant women before 14 weeks gestation, with IMA levels measured during the first, second, and third trimesters. The albumin cobalt binding test was used to determine the amount of ischemia-modified albumin (IMA). The patients’ medical, sociodemographic, and nutritional data were analyzed. The primary outcome was to investigate how changes in maternal ischemia affected albumin levels during pregnancy and the relationship between these changes and newborn weight. Results: This study included 43 cases with a mean age of 28.5 ± 5.2 years and a mean gestation period of 39.2 ± 1.3 weeks. The mean IMA levels for cases in the first trimester, second trimester, and third trimester were 0.53 ± 0.06, 0.64 ± 0.11, and 0.64 ± 0.06, respectively. The second and third trimesters showed significantly higher levels of ischemia-modified albumin (IMA) than the first trimester (p &lt; 0.01). There was no statistically significant difference in IMA levels between the second and third trimesters (p = 1.000; p &gt; 0.05). There was no statistically significant correlation between fetal birth and percentage changes in IMA measurements between the first and second trimesters, the first and third trimesters, or the second and third trimesters (p &gt; 0.05). Conclusions: Our study determined that maternal ischemia-modified albumin levels during pregnancy did not correlate with fetal birth weight. Our findings revealed that age, sociodemographic changes, BMI, weight gain, and pregnancy complications had no effect on the change in IMA levels during pregnancy. We believe that this result will serve as a benchmark for future studies on IMA levels during pregnancy.

Influence of Combined Supplemental Lighting and Nutrient Solution Concentration on Fruit Production and Quality of Cherry Tomato

We conducted an analysis on the combined effects of two light conditions (L1: greenhouse natural lighting; L2: greenhouse natural lighting plus supplemental lighting (SL)) and three nutrient solution concentrations (EC, NS1: 3.2 dS/m; NS2: 3.7 dS/m; NS3: 4.2 dS/m) on the growth, fruit production, and quality of two cherry tomato cultivars with different fruit coloring (‘Baiyu’ and ‘Qianxi’). The plants subjected to NS2 exhibited enhanced growth, photosynthetic parameters, and fruit production. The utilization of SL further enhanced stem diameter, leaf number, and single fruit weight, resulting in higher fruit weight per plant in ‘Baiyu’, which was not observed in ‘Qianxi’. The growth, fruit size, and fruit weight of both cultivars cultivated under NS3 conditions were suppressed, while these fruits exhibited elevated levels of total soluble solids (TSS), soluble sugars, vitamin C, polyphenols, fructose, glucose, sucrose, citric acid, and carotenoids. These levels were further enhanced by SL treatment. The improvement of fruit quality through the application of SL was found to be cultivar and EC dependent. In ‘Baiyu’, SL at NS1 significantly enhanced the accumulation of fruit water, minerals (N, P, K, Ca, and Mg), TSS, vitamin C, fructose, sucrose, and carotenoids. However, this effect was not observed in ‘Qianxi’. The combination of SL and EC 4.2 dS/m (NS3) generally contributes to the enhancement of fruit quality, while SL and EC 3.7 dS/m can ensure consistent fruit production. The yellowish-white fruit cultivar exhibited higher levels of soluble sugars, vitamin C, and polyphenols under L2NS3 conditions compared to the red fruit cultivar, whereas the carotenoid content showed an opposite trend. The findings are anticipated to establish a theoretical foundation for the consistent annual cultivation of cherry tomatoes in protected horticultural settings.

The Use of Horse and Donkey Meat to Enhance the Quality of the Traditional Meat Product (Kaddid): Analysis of Physico-Chemical Traits

The aim of this study was to evaluate the use of horse and donkey meat in the production of kaddid—a traditional dish typically not made with these meats—from a physical and chemical perspective. The results showed that both meats exhibit similar water retention during cooking, contributing to comparable tenderness and juiciness, with no significant differences in pH values, indicating similar quality (p &gt; 0.05). However, their amino acid profiles differ: horse meat contains lower levels of glutamate (p &lt; 0.05), methionine (p &lt; 0.01), isoleucine (p &lt; 0.05), and leucine (p &lt; 0.05), but higher levels of proline (p &lt; 0.05), histidine (p &lt; 0.01), and lysine (p &lt; 0.001) compared to donkey meat. Both meats provide essential amino acids. Horse meat is richer in saturated and monounsaturated fatty acids (32.44% and 39.58%, respectively), while donkey meat has a higher content of polyunsaturated fatty acids (31.51%), with a more favorable PUFA/SFA ratio, suggesting better cardiovascular health benefits. In terms of dried meat, donkey kaddid has a higher protein (17.45 g/100 g) and lower fat content (2.1 g/100 g) compared to horse kaddid (16.7 g/100 g, and 3.5 g/100 g, respectively) (p &lt; 0.05). These findings inform consumer choices and production practices, promoting the use of horse and donkey meat for kaddid production.

Posttraumatic growth among Israeli female combat veterans: The mediating roles of posttraumatic stress symptoms and self‐efficacy

AbstractPosttraumatic growth (PTG) is a possible common reaction to exposure to potentially traumatic events (PTEs) during military service. However, knowledge about correlates of PTG among female combat veterans is sparse. This study examines associations between combat exposure, posttraumatic stress symptoms (PTSS), general self‐efficacy (GSE), and PTG among Israeli female veterans. This is a cross‐sectional studyA volunteer sample of female Israeli combat veterans (n = 616) and non‐combat veterans (n = 484) responded to self‐report questionnaires. Combat veterans reported higher levels of combat exposure, PTSS, GSE, and PTG, as compared to non‐combat veterans. Among combat veterans, combat exposure and GSE were associated with greater PTG. Importantly, PTSS and GSE mediated the link between combat exposure and PTG. The study's findings are among the first to report about possible psychological growth outcomes among Israeli combat veterans. Clinicians treating female veterans coping with combat trauma should be aware of the heterogeneity of reactions to military service challenges and the importance of enhancing veterans' GSE to facilitate PTG.

Polyphenolic Screening and the Antioxidant Activity of Grape Pomace Extracts of Romanian White and Red Grape Varieties

Due to its valuable organic compounds, grape pomace represents a valuable resource in the creation of value-added food products. In this study, we investigated grape pomace hydroalcoholic extracts obtained by ultrasonication from two white and two red Romanian grape varieties. The phytochemical parameters, i.e., polyphenolics, flavonoids, anthocyanins, condensed tannins content, and antioxidant activity, were determined by UV-Vis spectrometry. The statistical analysis revealed that Tămâioasă Românească and Negru de Drăgășani, respectively, and Fetească Albă and Fetească Neagră are similar to each other. Significant differences among the pomaces obtained from different grape varieties were noticed in terms of their phenolic contents. The red varieties (Fetească Neagră and Negru de Drăgășani) were richest in terms of total phenolics and total anthocyanins, respectively. The antioxidant activity of extracts obtained from grape pomace showed that Negru de Drăgășani had the higher value due to its high amounts of polyphenols, followed by Fetească Neagră, Fetească Albă, and Tămâioasă Românească. Higher levels of bioactive polyphenolic substances, i.e., catechin, myricetin, resveratrol, and vanillic acid, were found in the pomace of Negru de Drăgășani extracts using high-performance liquid chromatography. These results emphasize the potential of the Negru de Drăgășani variety to be further exploited for nutritional and functional applications.
