Nutritional interventions and BMI dynamics: A comprehensive analysis of growth outcomes in pediatric populations

Introduction: This review article emphasizes the significance of Body Mass Index (BMI) and insulin-like growth factor-1 (IGF1) in evaluating pediatric growth outcomes, particularly for those at risk of undernutrition. The review explores the long-term health consequences of early BMI trajectories, especially their association with cardiometabolic profiles in adulthood. The article also examines the correlation between BMI, insulin-like growth factor 1 (IGF-1), and growth velocity, focusing on their complex interactions in malnourished and obese pediatric populations. Methods: A comprehensive literature search was conducted using PubMed, Google Scholar, and Scopus from 1985 to 2024, focusing on BMI, height growth velocity, IGF1 levels, and the effects of nutritional interventions on pediatric growth outcomes. Studies were included if they focused on children aged 0-18 years and evaluated the impact of BMI and/or nutritional interventions on growth outcomes, with English language articles being prioritized. Review Results: A total of 15 studies involving 4737 participants were analyzed. The review highlights significant findings including the normalization of growth hormone (GH)-IGF axis post nutritional rehabilitation in malnourished children, the rapid response of IGF-1 levels to nutritional interventions, and the influence of protein-rich diets on catch-up growth. Studies also showed that early nutritional support, particularly through human milk, significantly affects IGF-1 levels and that dietary protein intake correlates with IGF-I concentrations and growth in toddlers. Long-term studies indicated that severe malnutrition can have enduring metabolic effects, necessitating sustained nutritional strategies. Discussion: The review highlights the significance of early nutritional support and its impact on IGF-1 levels, which are crucial for healthy growth trajectories. The findings advocate for careful monitoring of early growth rates to optimize long-term health outcomes and stress the importance of adequate protein intake during early childhood. Conclusions: A balanced approach to nutrition, focusing on the interplay between BMI, growth velocities, and IGF1 levels, is crucial in pediatric care. Strategic nutritional interventions, especially those rich in protein, can effectively manage growth outcomes across different BMI categories and improve health trajectories in pediatric populations. This review underscores the need for comprehensive strategies to address nutritional deficiencies and manage growth effectively from infancy through adolescence

Plant diversity on the edge: floristics, phytogeography, fire responses, and plant conservation of Two Peoples Bay Nature Reserve in the context of OCBIL theory

Context There have been few long-term studies of the flora, phenology, and ecology of specific reserves in the species-rich flora of the Southwest Australian Floristic Region. Aims This project, extending over five decades, aimed to develop an authoritative flora list and acquire data on phenology, threatened species, endemism, old and young landscapes, phytogeography, old lineages, and fire responses at Two Peoples Bay Nature Reserve. Methods The study used botanical collection on repeat surveys, herbarium studies, granite outcrop surveys and comparative phytogeographic analyses from maps on the Western Australian Herbarium’s Florabase. Key results Floristic survey recovered 853 taxa, 26% of those known in the Albany local government area. Possibly as many as 950–1000 taxa will be found in the future. The herbarium collections are the second largest of any conservation reserve in the Albany area. Flowering was most evident in spring and least in autumn. Three declared rare species and 20 conservation priority species were identified, as were short-range endemics, old clades, and natural hybrids. Conclusions The flora is dominated by species predominantly from wetter forest regions. Consequently, Two Peoples Bay Nature Reserve is correctly placed within the Bibbulmun Botanical Province. Several hypotheses of OCBIL theory (which addresses old, climatically-buffered, infertile landscapes) were supported, with increased local endemism, ancient clades, and reduced rates of natural hybridisation identified for the granite inselberg OCBIL Maardjitup Gurlin/Mt Gardner. Implications Long term studies are invaluable for plant inventory. Continuing the minimal use of prescribed burning is advocated from plant data, in support of approaches to help conserve threatened animals.

No lasting effects of a severe drought event on plant community composition in experimental grassland

AbstractThe effect of severe drought in the summer 2018 on the plant community composition and overall diversity was investigated in a replicated long-term grassland experiment where nitrogen availability was manipulated. The possible plant community response to the drought and the possible role of selected plant traits were investigated using model-based ordination techniques, which were tailored to the sampled pin-point cover data. Contrary to our prior expectation, that the severe drought had lasting effects on the plant community, we could not detect any significant effects of the severe drought on the plant community composition or Hill–Shannon diversity the following year and 3 years later. Furthermore, we did not detect any significant mediating effect of nitrogen on the possible effects of severe drought. The possible reasons for the observed high resistance of the grassland community to the severe drought event are discussed. Lasting effects of drought on plant communities cannot be predicted from observations during or immediately after the drought.

The Long-Term Agroecosystem Research cropland common experiment at Northern Plains.

Cropland agriculture in the northern Great Plains is challenged by variable weather, agricultural intensification, and competing use for energy development. Innovative cropland practices that address these challenges are needed to ensure regional agriculture can sustainably meet future food, fuel, and fiber demand. In response to this need, the Northern Plains Long-Term Agroecosystem Research Network site established a cropland experiment in 2019 that contrasts prevailing and alternative practices at plot and field scales over a proposed 30-year time frame. The experimental site is located on the Area IV Soil Conservation Districts Cooperative Research Farm near Mandan, ND. Cropping practices for the first 6 years of the experiment were developed with input from stakeholders and include a 3-year crop rotation of spring wheat (Triticum aestivum L.), corn (Zea mays L.), and soybean (Glycine max L.) with cover crops (alternative practice) and without (prevailing practice). The prevailing practice also involves the removal of crop residue, while a second alternative practice of perennial forages is included in the plot-scale experiment. Biophysical measurements are made at both spatial scales at frequencies aligned with approved methods for each agronomic and environmental metric. Findings from the first 6 years of the experiment will help identify tradeoffs associated with cover crop use and residue removal in dryland cropping systems. In the future, the experiment will adopt a knowledge co-production approach whereby researchers and stakeholders will work collaboratively to identify problems, implement research, and interpret results.

The influence of connective tissue grafting on the reconstruction of a missing facial bone wall using immediate implant placement and simultaneous bone reconstruction: a retrospective long-term cohort study

PurposeThis retrospective cohort study evaluates the influence of connective tissue grafts (CTG) on bone regeneration at implant sites with total loss of the buccal bone wall treated with flapless immediate implant placement (IIP) and reconstruction with autogenous bone chips (AB) within a follow-up of up to 13 years.MethodsSixty implants were inserted in 55 patients in sites with total loss of the buccal bone wall between 2008 and 2021. The implants were inserted and the buccal gaps were grafted by AB. A subgroup of 34 sites was grafted additionally with CTG using tunnel technique. Primary outcome was the vertical bone regeneration in height and thickness. Secondary outcome parameters were interproximal marginal bone level, recession, soft tissue esthetics (PES), width of keratinized mucosa (KMW) and probing depths (PPD).ResultsMean follow-up period was 60.8 months. In 55 sites a complete vertical bone regeneration was documented. The mean buccal bone level increased by 10.6 mm significantly. The thickness of the buccal bone wall ranged between 1.7 and 1.9 mm, and was significantly thicker in sites without CTG. Interproximal marginal bone level was at implant shoulder level. The mean recession improved significantly by 1.2 mm. In sites with CTG, recessions and PES improved significantly more.ConclusionsAdditional CTG in extraction sites with total buccal bone loss followed by IIP with simultaneous AB grafting led to improved PES and recession, but also to a thinner buccal bone wall compared to sites grafted just with AB.Graphical

Insights into Nimbolide molecular crosstalk and its anticancer properties.

Nimbolide, one of the main ingredients constituent of Azadirachta indica (neem) leaf extract, has garnered attention for its potential as an anticancer agent. Its efficacy against various cancers and chemopreventive action has been demonstrated through numerous in vivo and in vitro studies. This updated review aims to comprehensively explore the chemopreventive and anticancer properties of nimbolide, emphasizing its molecular mechanisms of action and potential therapeutic applications in oncology. The review synthesizes evidence from various studies that examine nimbolide's roles in apoptosis induction, anti-proliferation, cell death, metastasis inhibition, angiogenesis suppression, and modulation of carcinogen-metabolizing enzymes. Nimbolide exhibits multifaceted anticancer activities, including the modulation of multiple cell signaling pathways related to inflammation, invasion, survival, growth, metastasis, and angiogenesis. However, its pharmacological development is still in the early stages, mainly due to limited pharmacokinetic and comprehensive long-term toxicological studies. Nimbolide shows promising anticancer and chemopreventive properties, but there is need for systematic preclinical pharmacokinetic and toxicological research. Such studies are essential for establishing safe dosage ranges for first-in-human clinical trials and further advancing nimbolide's development as a therapeutic agent against various cancers. The review highlights the potential of nimbolide in cancer treatment and underscores the importance of rigorous preclinical evaluation to realize its full therapeutic potential.

Human Health Risk Assessment of Radionuclide Contamination in Drinking Water

This study investigates the human health risks of uranium, radium, radon, and other drinking water radionuclides and their mitigation strategies. It was implemented through literature review, field sampling, and analytical methods. Samples were taken from various sources, including groundwater, surface water, municipal supplies, and private wells. ICPI-MS and liquid scintillation counters were used for radiation measurements. Statistical analysis and risk assessment models were used to measure health risks and treatment effectiveness. Groundwater sources were the main sources of radionuclides, with private wells being the main sources. The elimination efficiencies of reverse osmosis were exceptional, reaching up to 99%. The elderly population (60+ years) were the most likely to have cancer, with the highest risks for bladder cancer, lung cancer, kidney cancer, and leukemia. The frequency of radionuclide contamination in drinking water sources varied, with the U.S. Environmental Protection Agency, Nigerian EPA, and Canada having the strictest schedules. The results emphasize the urgent need for monitoring programs, effective treatment technologies, and targeted risk management strategies to cope with radionuclide contamination. Government advice includes improving the regulatory system, developing advanced treatment methods, long-term epidemiological studies, public awareness, interdisciplinary collaboration, scientific exploration of alternative water sources, and prioritizing interventions for vulnerable populations.

Long-term Effects of Iron Deficiency in Early Infancy on Neurodevelopment

Introduction and Purpose: Iron deficiency alongside anaemia is one of the most significant global health concerns with potentially long-lasting implications on child development and health outcomes. The period of infancy represents a crucial phase of central nervous system maturation, rendering infants particularly susceptible to the adverse effects of iron deficiency. It is therefore crucial to pay close attention to this issue. The aim of this review is to elucidate the neurological implications of iron deficiency in infancy and emphasize the necessity of implementing preventive strategies to safeguard child development. State of Knowledge: Iron deficiency in infancy can result in impairments of brain development. Extensive research highlights the influence of this micronutrient on various physiological processes, including the synthesis of neurotransmitters, neuronal metabolism, myelination, synaptogenesis and gene expression. Furthermore, iron deficiency during infancy is associated with adverse developmental outcomes, including cognitive, motor, and socioemotional deficits. Long-term follow-up studies have elucidated the enduring neurological consequences of iron deficiency in infancy, with effects extending into childhood and beyond. Summary: Given that the changes that occur during the infantile period are often irreversible and have long-lasting implications for future development, it is of the utmost importance to prioritize prevention strategies.

Review of foodborne helicobacteriosis

Helicobacteriosis is a common bacterial infection caused by Helicobacter pylori. It affects the stomach and small intestines, leading to inflammation. Bacteria can spread through contaminated food or water. This review explores the role of food in the transmission of H. pylori, drawing on research from the past three decades. People commonly acquire the infection during childhood, often from close family members. Crowded living conditions can also contribute to the spread. This review also discusses various risk factors and highlights the challenges of detecting H. pylori, particularly in its dormant form. Techniques like ribotyping and restriction fragment length polymorphism hold promise for tracing transmission routes, but more long-term studies are needed to account for potential confounding factors.

Effect of Soil Acidification on Temperature Sensitivity of Soil Respiration

Soil pH significantly impacts microbial activity and community assembly, which in turn determines the temperature sensitivity (Q10) of soil respiration. Due to the high soil acidification in China, it is necessary to understand how soil acidification impacts Q10. Here, the Q10 of soil respiration was examined in a long-term field experiment (1982–present) with different soil pH caused by fertilization management. In this experiment, we selected treatments with neutral pH: (1) no crops and fertilization (CK); (2) crops without fertilization (NF); low pH with (3) crops with chemical fertilization (NPK); and (4) crops with chemical fertilization combined with wheat straw incorporation (WS). Under natural soil temperature changes, we observed that soil acidification lowered the Q10 value of soil respiration. Considering only temperature changes, the Q10 of soil respiration was strongly associated with microbial community composition, alpha diversity, and soil ammonium nitrogen. Considering the interaction between soil pH and temperature, warming strengthened the negative effect of soil pH on the Q10 of soil respiration, and the pathway through which soil pH mediated Q10 included not only microbial community composition, alpha diversity, and biomass but also the soil’s available phosphorus. This work enhanced our insights into the relationships between Q10, temperature, and soil pH by identifying important microbial properties and key soil environmental factors.

Magnetic voluntary head-fixation in transgenic rats enables lifespan imaging of hippocampal neurons

The precise neural mechanisms within the brain that contribute to the remarkable lifetime persistence of memory are not fully understood. Two-photon calcium imaging allows the activity of individual cells to be followed across long periods, but conventional approaches require head-fixation, which limits the type of behavior that can be studied. We present a magnetic voluntary head-fixation system that provides stable optical access to the brain during complex behavior. Compared to previous systems that used mechanical restraint, there are no moving parts and animals can engage and disengage entirely at will. This system is failsafe, easy for animals to use and reliable enough to allow long-term experiments to be routinely performed. Animals completed hundreds of trials per session of an odor discrimination task that required 2–4 s fixations. Together with a reflectance fluorescence collection scheme that increases two-photon signal and a transgenic Thy1-GCaMP6f rat line, we are able to reliably image the cellular activity in the hippocampus during behavior over long periods (median 6 months), allowing us track the same neurons over a large fraction of animals’ lives (up to 19 months).

Natural History and Outcomes of Individuals with Functional Bowel Disorder: a 9-year Population-based Longitudinal Study.

Long-term studies characterizing the natural history of functional bowel disorder (FBD) from community-based settings and exploring association with psychological factors are sparse. We aimed to evaluate the evolution of symptoms, health outcomes, and association of FBD with psychological disorders in Chinese population. Individuals identified from random sampling of residents of Hangzhou, China participated in a baseline survey in January of 2010. Follow-up phone survey was conducted in December of 2018. FBD was diagnosed based on Rome III criteria. Among 452 individuals (mean age 44.6±15.3 years, 174 (38%) male) who completed the study, the prevalence of FBD was 36.3% (95%CI 32.6-40.0%) at enrollment and 36.1% (95%CI 32.3-39.8%) at follow-up survey (p=0.94). However, 214 (47%) individuals had interval change in diagnosis. Although no difference in incidence of organic disease or death was observed, a higher proportion of patients with FBD (16/164, 9.8% vs. 9/288, 3.1%; p=0.003) compared to those without FBD received non-cancer-related abdominal and/or pelvic surgery during follow-up. FBD was associated with anxiety and/or depression at initial (AOR=1.7, 95%CI 1.7-2.7, p=0.02) and follow-up (AOR=8.0, 95%CI 3.2-20.0, p<0.001) surveys. Diagnosis of FBD at baseline was associated with new-onset anxiety and/or depression at follow-up (OR=3.2, 95%CI 1.2-8.3, p=0.01). Although the prevalence of FBD remained stable, transformation of symptoms was common over time. Patients with FBD may have increased risk of receiving non-cancer related abdominal and/or pelvic surgery. FBD symptoms at baseline increased the risk of new-onset anxiety and/or depression by 3.2-fold over the next 9 years.

Comparative efficacy and safety of alpha-blockers as monotherapy for benign prostatic hyperplasia: a systematic review and network meta-analysis

Despite the availability of various drugs for benign prostatic hyperplasia (BPH), alpha(α)-blockers are the preferred first-line treatment. However, there remains a scarcity of direct comparisons among various α-blockers. Therefore, this network meta-analysis (NMA) of randomized controlled trials (RCTs) aimed to evaluate the efficacy and safety of α-blockers in the management of BPH. A comprehensive electronic search covered PubMed, Embase, Ovid MEDLINE, and Cochrane Library until August 2023. The primary endpoints comprised international prostate symptom score (IPSS), maximum flow rate (Qmax), quality of life (QoL), and post-void residual volume (PVR), while treatment-emergent adverse events (TEAEs) were considered as secondary endpoints. This NMA synthesized evidence from 22 studies covering 3371 patients with six kinds of α-blockers with 12 dose categories. IPSS has been considerably improved by tamsulosin 0.4 mg, naftopidil 50 mg and silodosin 8 mg as compared to the placebo. Based on the p-score, tamsulosin 0.4 mg had the highest probability of ranking for IPSS, PVR, and Qmax, whereas doxazosin 8 mg had the highest probability of improving QoL. A total of 297 adverse events were reported among all the α-blockers, silodosin has reported a notable number of TEAEs. Current evidence supports α-blockers are effective in IPSS reduction and are considered safer. Larger sample size with long-term studies are needed to refine estimates of IPSS, QoL, PVR, and Qmax outcomes in α-blocker users.

Effects of Maize/Peanut Intercropping and Nitrogen Fertilizer Application on Soil Fungal Community Structure

Maize/peanut intercropping may improve soil health through reducing nitrogen (N) fertilization. However, the effects of maize/peanut intercropping combined with reduced N fertilization on the soil fungal community structure have not been well reported. Using a long-term localized micro-zone experiment, we investigated the combined effects of intercropping and N fertilizer application on soil fungal community diversity and composition. Three cropping patterns (maize/peanut intercropping, maize monoculture, and peanut monoculture) and three N application levels (0 kg·hm−2, 150 kg·hm−2, and 300 kg·hm−2) were assessed. The results showed that the total numbers of fungal species and unique species (operational taxonomic units, OTUs) in both maize and peanut soils tended to first increase and then decrease with increasing N application. Compared with monoculture, the numbers of total OTUs and unique OTUs in intercropped maize soil decreased by 4.14% and 12.79%, respectively, but the total numbers of OTUs and unique OTUs in peanut soil increased by 1.08% and 3.78%, respectively. With increasing N application, the soil fungal Ace and Chao indices of maize soil first increased and then decreased, while the fungal Shannon, Ace, and Chao indices of peanut soil decreased. Compared with the monoculture system, intercropping significantly reduced the maize soil fungal Ace and Chao indices but increased the peanut soil fungal Shannon, Ace, and Chao indices. Nitrogen application and intercropping significantly altered the fungal community structure of maize soil, while N application had no significant effect on the fungal community structure of peanut soil, though intercropping significantly changed the fungal community structure of peanut soil. At the phylum level, Ascomycota, Basidiomycota, Mortierellomycota, unclassified_k_Fungi, and Chytridiomycota were the dominant taxa. Redundancy analysis (RDA) showed that soil nitrate (NO3−) content was the main environmental factor shaping the soil fungal community. In conclusion, excessive N fertilization (300 kg·hm−2) can reduce soil fungal community diversity; maize/peanut intercropping reversed the negative effect of N application on fungal community of peanut soil, but not that of maize soil. Soil NO3− content is the primary environmental driver of soil fungal communities.

Utilization of graphene as an alternative sustainable amendment in improving soil health through accelerated decomposition of oil palm mulch and enhanced nutrient availability

Graphene has unique properties for improving soil health properties such as nutrient availability, soil physical and chemical properties, and controlled release of essential elements. This research aimed at determining the impact of graphene amendment on the decomposition of oil palm frond mulching and on soil health status. The study was conducted using a factorial experiment in completely randomized design with two main factors: (i) covering conditions: cover with plastic sheet and no cover, and (ii) graphene application that included T1 (control): oil palm frond mulching (OFM), T2: OFM + graphene (G), T3: OFM + G + chemical fertilizer, and T4: OFM + G + goat manure. The results indicated that there were significant differences among graphene applications, between cover conditions, and in interactions between graphene applications and cover conditions for all soil characteristics in the most observed month. In the third month of soil analysis, the treatment of graphene applications showed higher electrical conductivity (T2: 151.7 ± 6.8 µS cm−1), available phosphorus (T3: 9.0 ± 6.7 mg kg−1), exchangeable potassium (T2: 67.1 ± 24.9 mg kg−1), and exchangeable calcium (T3: 95.4 ± 5.1 mg kg−1), compared to control. The cover condition showed suitable soil pH (5.0 ± 0.2), higher soil available phosphorus (7.1 ± 5.0 mg kg−1), and exchangeable calcium (599.1 ± 235.2 mg kg−1), but the no-cover condition presented higher soil organic matter (0.7% ± 0.2%), exchangeable potassium (60.3 ± 19.1 mg kg−1), and exchangeable magnesium (96.7 ± 11.4 mg kg−1). Correlation results indicated that most soil characteristics were correlated under graphene applications. Principal component analysis showed that the treatments of graphene application dominated most soil characteristics. The results suggest that graphene has potential for improving soil health properties and can be applied as an alternative sustainable amendment to accelerate the decomposition of oil palm frond mulch and enhance nutrient availability for oil palm. In addition, the authors suggest that further investigations should consider more soil health parameters in long-term field studies for a better understanding and to provide recommendations to farmers.

Comparison of traditional growth rods and magnetically controlled growing rods in early-onset scoliosis: a case-matched mid term follow-up study.

Early-onset scoliosis (EOS) has always been a challenging situation for spine surgeons. The aim of treatment is to control the direction of curve progression to allow for the complete development of lungs. Among all the growth constructs available, traditional growth rods (TGR) and magnetically controlled growth rods (MCGR) are most widely used. The MCGR has been introduced a few years back and there is a dearth of long-term follow-up studies. The purpose of this study is to compare the effectiveness of TGR and MCGR for the treatment of EOS. All patients of EOS managed with either TGR or MCGR were included in the study. The patients managed with other methods or having follow-up < 2-years were excluded from the study. A total of 20 patients were recruited in the MCGR group and 28 patients were recruited in the TGR group. Both groups were matched by etiology, gender, pre-operative radiological parameters, and complications including unplanned surgeries. The mean age in our study was 7.90years in the MCGR group and 7.46years in the TGR group. The mean duration of follow-up in the MCGR group was 50.89months and in the TGR group 94.2months. Pre-operative cobb's angle in the coronal plane and T1-S1 were comparable in both groups with a mean cobb's angle of 65.4 in MCGR and 70.5 in TGR. The mean T1-S1 length in the MCGR group was 36.1cms and in the TGR group was 35.2cms (p = 0.18). The average increase in T1-S1 length was 1.3cm/year in the TGR group and 1.1cm/year in the MCGR group (p > 0.05). The TGR patients underwent 186 open lengthening surgeries and 11 unplanned surgeries for various complications. The MCGR group has 180 non-invasive lengthening with only 4 unplanned returns to OT for various causes. The curve correction was similar in both TGR and MCGR groups. The average T1-S1 length achieved on final follow-up was similar in both groups. The MCGR patients have attained similar correction with fewer invasive procedures and lesser complications compared to the TGR group.

Thermal assessment of cylindrical parabolic integrated collector storage using input-output and dynamic system testing procedures: Experimental and numerical study

The main limitation of Integrated Collector Storage systems lies in their low efficiencies and high loss coefficients. In this paper, experimental and numerical setups are conducted to assess the thermal performances of low cost Cylindrical Parabolic Integrated Collector storage (CP-ICS). The conceived system has two aluminum plates in parabolic form serving as reflectors, each with a surface area of 2 m2. The storage tank has a volume of 160 L covered with a layer of black paint with single and double transparent insulations. Results of the experimental tests using Input-Output method showed that the daily thermal efficiency ηd of the developed systems is equal to 48.21% and 49.46% for single and double insulation cover configurations, respectively. The total store heat capacity Cs, the useful collector surface Ac* and the storage tank heat losses coefficient Us of the system found using Dynamic System Testing procedure are equal to 0.56 MJ/K, 0.74 m2 and 1.59 W/K, respectively. Even if the energy efficiency of the system is slightly lower than that recorded in conventional systems, numerical results of long-term study using TRNSYS software showed that the system provides a reasonable solar fraction for the needs of a family in Tunisian climate. A comparative assessment of the developed solar collector performances in different representative climates showed that the use of the CP-ICS system presents a promising solution for countries with annual ambient temperatures fluctuating from 13°C to 33°C, such as Araxos with a solar coverage of 30.65% for a daily supply volume of 160 L. More importantly, in Faya-Largeau location, presenting Chadian climate data, the solar fraction is found to be the highest and reached an average of 67.25%.

Evaluation of antioxidant enzyme levels, oxidative stress markers and serum prolidase activity in testicular cancer.

Testicular cancer is a significant malignancy affecting males, and understanding the underlying biochemical changes associated with the disease is essential for improved management and treatment strategies. Prolidase enzyme, has been implicated in various disease processes. The assessment of serum prolidase activity and its relationship with testicular cancer can provide valuable insights into the pathophysiology of the disease. The objective of this study was to investigate serum prolidase activity, oxidative stress markers, and antioxidant enzyme levels in patients with testicular cancer and evaluate their potential associations, aiming to enhance our understanding of the biochemical alterations and potential implications for testicular cancer management. A total of 33 male patients diagnosed with testicular cancer were included, along with 35 age-matched male volunteers as the control group. Serum samples were collected and stored at -20°C until analysis. The measurement of superoxide dismutase (SOD), glutathione peroxidase (GSHPx), glutathione-S-transferase (GST), malondialdehyde (MDA), glutathione (GSH), and prolidase levels was performed. The findings demonstrated significantly elevated serum prolidase activity and malondialdehyde (MDA) levels in testicular cancer patients compared to the control group (all, p < 0.05). Conversely, superoxide dismutase (SOD), glutathione peroxidase (GSHPx), and glutathione-S-transferase (GST) levels were significantly lower in testicular cancer patients (p < 0.05). In this study, serum prolidase activity and biochemical markers associated with oxidative stress were investigated in testicular cancer patients. Oxidative stress markers and serum prolidase activity were found to be elevated in testicular cancer. Long-term prospective studies are needed to determine the effectiveness of antioxidant use in cancer treatment.

Enteral nutrition compared with corticosteroids in children with Crohn's disease: A long-term nationwide study from the epi-IIRN.

Both corticosteroids and exclusive enteral nutrition (EEN) have been used as induction therapy in children with Crohn's disease (CD). To compare in a nationwide studythe long-term outcomes of children with CD receiving either EEN or corticosteroids as induction therapy. We retrieved data of all children diagnosed with CD (2005-2020) from the epi-IIRN cohort covering 98% of the Israeli population. The primary outcome was time to complicated disease course (i.e., surgery, steroid-dependency, or at least 2 biologic class). Patients were matched individually utilising propensity score adjustments. We included 410 children treated with EEN and 375 with corticosteroids without other treatments (median follow-up, 4.73 [IQR: 2.2-7.2] years [1433 patient-years]). For 274 matched children, the probability of a complicated course was higher with corticosteroids than EEN at 0.5, 3 and 5 years (14% vs. 4%, 42% vs. 27% and 54% vs. 41%, respectively, p = 0.0066), despite similar use of biologics. Steroid-dependency (10% vs. 2%, 15% vs. 3%, and 20% vs. 5%, respectively, p = 0.00018), and hospitalisations (20% vs. 11%, 37% vs. 26%, and 55% vs. 38%, respectively, p = 0.002) were higher with corticosteroids. During follow-up, children receiving corticosteroids as induction treatment were more often further exposed to corticosteroids, and those on EEN were more often further exposed to nutritional treatment (p < 0.001). Induction with EEN had no advantage over corticosteroids regarding survival probability of surgeries, biologic use and growth. EEN in paediatric CD is associated with lower long-term risks of corticosteroid dependency and hospitalisation than corticosteroids. These results may lend support to favouring nutritional therapy in paediatric CD.

Adaptive potential of winter common wheat varieties in the Penza region

The current paper has presented the results of long-term study (2014–2023) of productivity, adaptability parameters and correlation between a genotype and environment of winter common wheat varieties in the forest-steppe conditions of the Penza region. The purpose of the study was to determine the response of winter common wheat varieties in changing agroclimatic conditions according to productivity. The vegetation conditions during the years of study varied in temperature and amount of precipitation, which served as a good background for conducting research on the issue in question. The objects for the study were 9 zoned varieties approved for cultivation in the Middle Volga region and 5 winter common wheat varieties developed by the FSBRI CBFC. The zoned winter common wheat variety ‘Fotiniya’ was used as a standard. The years of the varieties’ study were divided into favorable, typical (mean) and unfavorable (dry, excessively wet). Winter common wheat productivity in favorable years averaged 5.68 t/ha, in typical years it was 4.32 t/ha and 2.19 t/ in unfavorable years. As a result of determining the response of winter common wheat varieties in changing agroclimatic conditions according to productivity, there was proven a strong effect of environmental conditions and genotype. There have been proposed for breeding use such valuable and stable genotypes of winter common wheat as ‘Biryuza’, ‘Skipetr’, ‘Don-eko’, ‘Alyonushka’, ‘Pamyati Krivobocheka’, ‘Surskaya Nika’, ‘Dargo’, which should be placed on a high and medium agricultural background. The varieties ‘Fotiniya’ and ‘Klavdiya 2’ are highly adaptable to unfavorable cultivation conditions and will have an advantage over other varieties in medium and low agricultural backgrounds.
