Investigation on the Effect of Sacoglottis gabonensis on Blood Glucose, Body Weight and Behavioural Changes of Mice Exposed to Non-nutritive Sweeteners during Gestation Period

Aim: Aim of this research was to investigate the role of Sacoglotts gabonensis on blood sugar, body weight and behavioural changes of mice exposed to artificial sweeteners. Study Design: A total of 16 female mice (mean weight 18.6±2.32g) divided into four groups were used in this study. Methodology: Group A received no sweeteners or S. gabonensis, B received 50mg of sweeteners only, C received 50mg of sweeteners and 250mg/kg/bw of S. gabonensis, D received 250mg/kg/bw of S. gabonensis only for 8weeks. Results: show that group A and D had significant (p<0.05) decrease in blood glucose concentration with 7.27±3.53 mmol/L and 8.22±1.87 mmol/L respectively compared to group B and C with 9.12±1.03 mmol/L and 8.22±1.87 mmol/L. There was a significant (p<0.05) increase in body weight in groups A 32.60±7.34g and B 31.38±4.53g compared to groups C, 22.45±15.49g and D, 24.00±14.71g. Gestation length was between 19 and 20 days for the different groups and behavioural changes such as climbing, running, nesting and restlessness were observed in all the groups. Conclusion: The administration of S. gabonensis did not alter gestation length and behavioural changes during gravid period in experimental animals but altered the blood glucose concentrations However, administration of S. gabonensis is recommended for individuals who are at risk of developing high blood glucose concentration and increased body weight as it has shown modulatory effect on blood glucose and body weight gain.

Ketogenic Food Ameliorates Activity-Based Anorexia of Adult Female Mice.

Genome-wide association studies implicate metabo-psychiatric origins for anorexia nervosa (AN). There are two case reports totaling six adult females who experienced complete remission of AN following a treatment comprised of ketogenic diet (targeting metabolism) with ketamine infusions (targeting psychiatric origins), but no study has determined the efficacy of ketogenic diet, alone. We addressed this gap in knowledge, with exploration of potential molecular mechanisms, using an animal model. Adult C57BL6 female mice underwent 2 or 3 cycles of activity-based anorexia (ABA1, ABA2, ABA3), an animal model of AN relapse, in which AN-like maladaptive behaviors of hyperactivity and voluntary food restriction are elicited when wheel access is combined with food restriction. ABA was categorized as severe, based on weight loss ≥ 20%, food restriction-evoked increase in wheel counts > 10,000/6 h, and crouching/grimace, and compared across two groups: (1) KG, fed ketogenic food continuously (N = 25); and (2) CON, fed standard diet (N = 28). 86% of CON versus none of the KG were crouching with grimace during ABA1. 93% of CON versus 11% of KG lost weight severely during ABA2 (p < 0.001, 8% difference of group mean weights). Severe hyperactivity was prevalent among CON (86%) and rare for KG (4%) during ABA2 (p < 0.001 on all food-restricted days). ABA up-regulated BDNF (brain-derived neurotrophic factor) in the hippocampus of both groups but ketone body, β-hydroxybutyrate, in urine was increased only among KG. Ketogenic diet may reduce severity of AN relapse through reduction of compulsive exercise, via mechanisms that are in addition to BDNF up-regulation and involve β-hydroxybutyrate.

Impact of Land Use Conversion on Soil Structure and Hydropedological Functions in an Arid Region

ABSTRACTLand use conversion critically affects soil structure and associated functions. This study investigated variations in soil structure and hydropedological characteristics across different land use types, that is, uncultivated, cultivated, and abandoned land under an arid condition. Water‐stable aggregates in the uncultivated land were 15.4%–37.1% of those in the cultivated and abandoned lands at depths of 0–60 cm. Reclamation of the uncultivated land enhanced soil aggregate stability, while prolonged tillage led to the loss of binding organic matter, breakdown of large aggregates and decrease in aggregate stability. The mean weight diameter of aggregates at 0–40 cm depth in the cultivated land was 39.0% lower than in the abandoned land. The volume fraction of micropores (&lt; 100 μm) in the cultivated soils was 3.7%–39.7% of that in the uncultivated soils, whereas macropores (&gt; 1000 μm) was 1.4–1.8 times greater. Following the abandonment, soil pore diversity recovered and a hierarchical structure developed. In the abandoned land, the volume fraction of micropores (&lt; 100 μm) was 2.4–18.9 times that of the cultivated lands, while macropores (&gt; 1000 μm) constituted 81.4%–93.9% of those in the cultivated lands. The permeability and longitudinal dispersivity of soils in the cultivated land were significantly lower than in the uncultivated and abandoned lands, particularly at deeper soil layers. The increase in large pores in the abandoned land, important for water movement and solute transport, resulted in an order‐of‐magnitude rise in both permeability and longitudinal dispersivity compared with the cultivated lands. Overall, the abandoned land showed potential for rehabilitation from the perspectives of soil aggregates and pore structure. The findings may provide reference for land reclamation and management in arid regions.

Clinical and laboratory antenatal profile screening and its associate factors among pastoralist women in Northern Part of Kenya

IntroductionAll pregnant women are encouraged to visit Antenatal Care (ANC) during pregnancy to ensure their wellbeing and that of their unborn baby. World Health Organization (WHO) recommends that all pregnant women attend antenatal clinics for care at least eight times during pregnancy. During antenatal care a series of essential tests are done for pregnant women, both clinical examination and laboratory screenings to detect potential issues which will guide clinicians on management. This study aims to investigate the clinical examination and laboratory screening profile results of pastoralist pregnant women and its associated factors during their first ANC visit in Marsabit County, Kenya.MethodsA cross-sectional study was conducted among pregnant women who attended Integrated Maternal Mobile (IMMH) outreach clinics for ANC in 10 mobile pastoralist communities. Data were collected on demographic information, clinical examination information, and laboratory profile screening outcomes. Frequency and percentages were used to describe the categorical variables and means and standard deviations were used to describe the continuous variables. Bivariate and multivariate analysis was conducted using IBM SPPS 27.0 following STROBE guidelines. The level of significance was set at p &amp;lt; 0.05.ResultsData (N = 237) were extracted, the mean age was 26.62 ± 5.371, of which the majority were in the age group of 20–29, 212 (89.5%) were married 180 (75.9%) and multigravida, 27 (11.4%) visited ANC and 121 (51.1%) traveling more than 15 km to seek healthcare services. The mean weight was 55.56 ± 9.019 kg, mean blood pressure systolic was 118.94 ± 19.95 mmHg, and diastolic was 73.87 ± 13.46 mmHg. Out of all specimens processed and tested, 135 (57%) were anaemic with Hgb &amp;lt;11.5 g/dL), 6 (2.5%) had malaria, 8 (3.4%) were hepatitis B positive, and 21 (8.9%) showed intestinal infection. Those women who are illiterate displayed a 12-fold higher likelihood of becoming anaemic during pregnancy (OR 11.50, 95% CI: 2.47–53.47), and those who didn’t attend ANC also have a 5-fold higher likelihood of being anaemic (OR 5.43, 95% CI: 2.52–11.70).ConclusionAnaemia, hepatitis B, syphilis, malaria parasites, intestinal parasites, and urinary tract infections were observed among the study participants. Integrated outreach programs with laboratory screening and health education should be enhanced, and women within pastoralist communities should be empowered through health education.

Risk Factors Associated with Weight Gain during Treatment with Dupilumab among Patients with Moderate to Severe Atopic Dermatitis.

This cohort study used prospectively collected data from the Swedish national quality registry, SwedAD, to investigate weight gain as a possible side effect of dupilumab treatment for atopic dermatitis. Patients on dupilumab were compared with patients on other systemic medications, e.g., methotrexate, cyclosporine, or Janus kinase inhibitors, and possible risk factors for weight change during treatment with dupilumab were analysed. All patients aged 18 years or above, included in SwedAD between March 2018 and April 2023, who initiated systemic treatment at or after inclusion and had data on weight at baseline and at least 1 follow-up weight measurement were included (n = 157). After 2 years on dupilumab, patients had a mean weight gain of 1.6 kg (p = 0.007, 95% confidence interval [CI] 0.4-2.7). In the multivariable analysis, controlling for age at start, sex, asthma, and body mass index at start, dupilumab was associated with higher weight gain than other systemic treatments (3.3 kg, p = 0.005 [95% CI1.0-5.6]). Asthma was associated with weight loss; male sex tended to be associated with weight gain.

BS O05 - Prevalence and Patterns of Iron Deficiency in Patients Living with Obesity: Insights from Bariatric Surgery Candidates

Abstract Background Iron deficiency anaemia (IDA) is a recognised complication of obesity, and its associated co-morbidities. Iron deficiency has been implicated in immunologic dysfunction in obesity. However, the patterns of iron deficiency in people with obesity, independent of IDA, and its implications for patients with obesity remain unclear. This study aimed to investigate potential causes of iron deficiency, including relationship with glycaemic control and relationship with systemic inflammation. Relationship between iron deficiency and body mass index (BMI) was also considered. Method A retrospective review of a prospectively maintained database of consecutive patients undergoing bariatric surgery was performed. Pre-operative haematologic assessments were reviewed, and linear regression models were used to identify the associations of iron deficiency in patients with obesity. Statistical analysis was performed using SPSS. 384 consecutive patients over a 2-year time period were included in the analysis. 72.1% of patients were female and the mean age was 49.44±10.2. The mean weight of included patients was 144.1±31.02 kg, and the mean BMI was 50.66±9.61 kg/m2 Results ​2.45% of patients met the criteria for iron deficiency anaemia. However, 15.49 % had low serum iron(&amp;lt;9 mmol/L), 12.1% had low ferritin(&amp;lt;30mg/L), 1.38% had low transferrin(&amp;lt;2g/L), 15.17% had high Total Iron Binding Capacity(&amp;gt;71.6mmol/L), 37.93% had low transferrin saturation(&amp;lt;20%). High BMI was a significant predictor of low serum iron(β=-0.206, p=0.031). Dysregulated glycaemic metabolism(HbA1c and glucose) was not a significant predictor of iron deficiency. Baseline inflammation (elevated CRP) was associated with low serum iron(β=-0.320, p=&amp;lt;0.001) and low transferrin(β=-0.205, p=0.028). Conclusion Iron deficiency in patients with obesity is common, but not iron deficiency anaemia dependent. It does not appear to be linked to patients’ glycaemic regulation, as previously thought. Our findings suggest it may instead be attributable to the systemic inflammation caused by obesity.

Effect of feeding guava agroindustrial waste on nutrient utilization, lamb performance and economic analysis

Abstract. Our study sought to investigate the impact of incorporating guava agroindustrial waste (GAW) at varying concentrations on nutrient utilization, lamb performance and economic viability. Forty non-castrated, 4-month-old Santa Inês lambs with an initial mean weight of 21.3 ± 2.18 kg were utilized in a confined setting. These lambs were allocated randomly to five treatment groups, each consisting of eight replicates, and were subjected to diets containing increasing levels of GAW (0 %, 7.5 %, 15 %, 22.5 % and 30 % based on dry matter). The feed formulation also included Tifton hay, corn, soybean and mineral salt. Throughout the trial period, parameters such as dry matter intake (DMI), nutrient digestibility and economic metrics were meticulously evaluated. Notably, the performance metrics among the different GAW treatments did not exhibit statistically significant differences (p &gt; 0.05), with an average daily gain of 328 g d−1 observed across all the groups. However, there was a discernible positive effect on the intake of ether extract (p &gt; 0.05). Regarding nutrient digestibility, only the crude protein digestibility demonstrated no significant variance (p &gt; 0.001) among the treatments. Consequently, our findings suggest that GAW can be effectively integrated into sheep diets at levels of up to 30 % without compromising lamb performance. Moreover, from an economic standpoint, this incorporation proves to be the most financially viable and cost-effective option among the evaluated treatments.

Abstract 4120229: Shift in body mass index category and associated cardiometabolic risk factors: a post hoc analysis from the SURMOUNT-4 trial

Background: In SURMOUNT-4, participants with obesity demonstrated a mean weight reduction of 21% during the 36-week lead-in with the maximum tolerated dose (MTD) of tirzepatide (TZP). During the 52-week double-blind period, participants who switched to placebo (PBO) experienced a 14% weight regain, while those who continued TZP achieved an additional 6% weight reduction. This post hoc analysis assessed whether participants who shifted to a lower BMI category had improved cardiometabolic factors. Methods: Shift in BMI category (&lt;25 kg/m 2 , 25 to &lt;30 kg/m 2 , 30 to &lt;35 kg/m 2 , 35 to &lt;40 kg/m 2 , and ≥40 kg/m 2 ) from baseline (week 0) during the lead-in period (week 36) and at the primary endpoint (week 88) and from week 36 to week 88 was assessed in participants from SURMOUNT-4 randomized to TZP MTD (N=332) or PBO (N=329). BMI shifts were grouped into “improved” (shift to ≥1 lower category) or “not improved” (stable/attenuated [no change/shift to a higher category]). Changes from baseline in waist circumference, fasting insulin, fasting glucose, HbA1c, vitals and lipid profile were assessed. Results: From weeks 0 to 36, 296 (89%) participants improved in BMI category with TZP, and none had attenuated (Table). From weeks 36 to 88, 130 (39%) participants improved in BMI category with TZP, while the majority (99%) randomized to PBO did not. Overall, from weeks 0 to 88, 304 (92%) vs 189 (57%) participants improved in BMI category with TZP vs PBO, respectively, where the improvements observed in the PBO group originated from the 36-week lead-in period. In general, participants who improved in BMI category at week 88 were noted to have greater improvements in cardiometabolic parameters with TZP vs PBO, including decreases from baseline in waist circumference, fasting insulin, fasting glucose, HbA1c, blood pressure, triglycerides, and cholesterol (total, non-HDL-c, LDL-c, and VLDL-c). Conclusions: In this post hoc analysis of SURMOUNT-4, the majority of TZP-treated participants shifted to lower “improved” BMI categories. Shift to an improved BMI category was accompanied by improved cardiometabolic risk factors, suggesting that TZP treatment may lower further cardiovascular outcomes. Relevant outcomes trials are ongoing.

Thoracotomy patch repair of large diaphragmatic herniae in a porcine model: a tale of two patches.

Congenital diaphragmatic herniae (CDH) may require patch closure in 50% of the cases. We assessed a biologic and composite mesh in aporcineCDH model. Left sided thoracotomy was performed in 20 pigs. Approximately, 30% of the diaphragm was excised and the patch (Surgisis® or Parietex®) inserted to close this defect. The pigs were killed at 6months and the diaphragm was harvested for biomechanical and histological assessment. The mean weight of the pigs at surgery and killing were 6.1kg (4.2-8.4kg) and 94.1kg (80-131kg), respectively. There were two recurrences and three eventrations, all with Surgisis®. There were less dense lung and abdominal adhesions in the Parietex group (P < 0.0001 and 0.025, respectively). The tensile strength of the Surgisis®, the Parietex® groups and controls were similar. There was significantly more muscle in-growth in the Parietex® patch over Surgisis® (p = 0.016). Parietex® and Surgisis® patches at 6months have a similar tensile strength to normal tissue. All recurrences and eventrations were in the Surgisis® group. Parietex® patches demonstrated more muscle in-growth into the patch compared to Surgisis®. This is the first study utilising Parietex® composite patch in the repair of large diaphragmatic defects in a porcine model.

Age Structure, Body Size, and Sexual Dimorphism in a High-Altitude Population of Pelophylax ridibundus (Pallas, 1771)

This study aimed to describe the morphological characteristics and age structure of a P. ridibundus population sampled from a high altitude. For this purpose, a total of 54 adult frogs (33 males and 21 females) were collected from Şavşat district, Artvin province, Türkiye. The samples were aged based on skeletochronology method. Furthermore, von Bertalanffy growth curve models were constructed using SVL and weight data. To assess sexual size and shape dimorphism, the measurements of 23 different morphological characters were analyzed using univariate and multivariate statistical techniques. The mean SVL and weight were found to be 78.05 mm and 60.87 g for males and 93.95 mm and 109.61 g for females. The mean age was 3.67 years and 4.05 years for males and females, respectively. The maximum age was found to be 6 years for both sexes. Growth curve models revealed a significant relationship between age, SVL, and weight. A clear female-biased sexual size dimorphism was found in all morphological characters. However, SVL-adjusted values indicated that males had larger head and limb structures resulting from evolutional and sexual pressures associated with reproduction and male–male competition. The shape dimorphism was found only in forelimbs, and it was male-biased and was related to clasping in amplexus.

Comparison of Necrotizing Enterocolitis After Surgical Norwood versus Hybrid Stage 1 Palliation.

Hybrid stage 1 palliation (HS1P) is used as an alternative to the surgical Norwood for single ventricle patients and specific other conditions. Necrotizing enterocolitis (NEC) occurs in 5%-18% of infants after surgical Norwood, contributing to significant morbidity. We sought to compare the NEC incidences in HS1P versus Norwood patients. A single-center retrospective cohort study of all infants undergoing HS1P or Norwood over a 12-year period. Demographics, underlying cardiac diagnosis, surgical details, and NEC episodes were queried for each patient. The cumulative incidences of NEC between HS1P and Norwood patients were compared. A total of 305 infants were included; 200 Norwood and 105 HS1P. HS1P infants were more often premature (gestational age < 37weeks; 23.8% vs 1.5%) and had lower birth weight (mean 2.8 ± 0.66kg versus 3.3 ± 0.47kg) than their Norwood counterparts. Most infants who underwent the Norwood procedure had hypoplastic left heart syndrome (79.5%), with variable underlying cardiac diagnosis for those who underwent HS1P. Incidence of NEC was significantly higher in the HS1P group (53.3% versus 37.0%, p = 0.01), with increased risk independent of birth weight or underlying cardiac diagnosis (adjusted odds ratio 1.8, p = 0.03). Infants after HS1P had a median of 2 episodes of NEC (interquartile range [IQR] 1-3) versus 1 episode in the Norwood group (IQR 1-2). Infants after HS1P are at higher risk of NEC in comparison to infants after the Norwood procedure. More studies are needed to help predict which infants after HS1P are at highest risk for NEC.

Spatial Distribution and Temporal Variation of Megafauna in Circalittoral and Bathyal Soft Bottoms of the Westernmost Biodiversity Hotspot of the Mediterranean Sea: The Alboran Ridge

The Alboran Sea is the westernmost sub-basin of the Mediterranean Sea, and it is connected to the Atlantic Ocean through the Strait of Gibraltar. The Alboran Ridge is located in the middle of the Alboran Sea and represents a hotspot of biodiversity in the Mediterranean Sea. Besides their critical importance, there are few studies on the communities and changes in biodiversity, and they mostly concentrate on infralittoral and circalittoral bottoms. In this work, the composition, structure and bathymetric and temporal changes of megafauna of the Alboran Ridge were examined. Samples were collected from MEDITS surveys carried out between 2012 and 2022 at depths ranging from 100 to 800 m. Analyses were performed separately for each of the taxonomic groups: osteichthyes, chondrichthyes, crustaceans, molluscs, echinoderms and “other groups”. There was no common spatial organization for each of the faunistic groups studied, although most of them displayed differences between the shelf and the slope. The continental shelf was characterized by the highest values of community metrics such as abundance, biomass, species richness and mean weight of species for all groups except for chondrichthyes and crustaceans. Decreasing trends of some community metrics were detected in some of the faunistic groups throughout the study period.

The Effect of the Construction of a Tillage Layer on the Infiltration of Snowmelt Water into Freeze–Thaw Soil in Cold Regions

The snow melting and runoff process in the black soil area of Northeast China has led to soil quality degradation in farmland, posing a threat to sustainable agricultural development. To investigate the regulatory effect of tillage layer construction on the infiltration characteristics of snowmelt water, a typical black soil in Northeast China was selected as the research object. Based on field experiments, four protective tillage treatments (CK: control treatment; SB: sub-soiling treatment; BC: biochar regulation treatment; SB + BC: sub-soiling tillage and biochar composite treatment) were set up, and the evolution of soil physical structure, soil thawing rate, snow melting infiltration characteristics, and the feedback effect of frozen layer evolution on snowmelt infiltration were analyzed. The research results indicate that sub-soiling and the application of biochar effectively regulate soil aggregate particle size and increase soil total porosity. Among them, at the 0–10 cm soil layer, the soil mean weight diameter (MWD) values under SB, BC, and SB + BC treatment conditions increased by 6.25%, 16.67%, and 19.35%, respectively, compared to the CK treatment. Sub-soiling increases the frequency of energy exchange between the soil and the environment, while biochar enhances soil heat storage performance and accelerates the melting rate of frozen soil layers. Therefore, under the SB + BC treatment conditions, the maximum soil freezing rate increased by 21.92%, 5.67%, and 25.12% compared to the CK, SB, and BC treatments, respectively. In addition, sub-soiling and biochar treatment effectively improved the penetration performance of snowmelt water into frozen soil layers, significantly enhancing the soil’s ability to store snowmelt water. Overall, it can be concluded that biochar regulation has a good improvement effect on the infiltration capacity of surface soil snowmelt water. Sub-soiling can enhance the overall snowmelt water holding capacity, and the synergistic effect of biochar and deep tillage is the best. These research results have important guiding significance for the rational construction of a protective tillage system model and the improvement of the utilization efficiency of snowmelt water resources in black soil areas.

Correlation of Lipid Profile and BMI with Fasting Blood Glucose

The prevalence in Libya of overweight people has more than tripled from 19.5% in 1984 to 63.5% in 2009, while the rate of obesity has more than doubled over the past three decades leading to a much higher incidence of Type 2 diabetes T2DM. This makes investigation of links between BMI and lipid profiles in Libyan T2DM patients of vital importance. This study was conducted to determine the cor-relation between body mass index (BMI) and lipid profiles in patients with T2DM attending outpatient clinics in the Diabetes and Endocrinology Centre (Ibn Al-Nafees Hospital) Tripoli, Libya. The second objective was to compare BMI, FBS and lipid profiles between T2DM patients and a control group. The study was carried out during the period of June and July 2024 included 122 T2DM patients and 55 healthy subjects. The subject’s serum was analysed for total cholesterol (TC), triglyceride (TG), high density lipoprotein cholesterol (HDL-C) and low-density lipoprotein cholesterol (LDL-C). The possible correlation of BMI with lipid values were analysed. The Pearson’s co-efficient between the BMI and the lipid parameters did not show any significant correlation in T2DM patients. Comparisons of various parameters between T2DM patients and the control group showed that the mean values of fasting glucose levels, weight, BMI, TG, HDL-C and LDL-C were significantly higher in the T2DM group than the control group. There was no correlation found between BMI and lipid profiles in T2DM patients. Type 2 diabetic patients have significantly higher mean weight, BMI, FBS, TG, HDL-C and LDL-C compared with healthy controls

Zeolites – tabletting ibuprofen with and without zeolites as an excipient

Abstract Introduction Drug delivery via the oral route is a patient and industry-preferred approach. However, maintaining plasma concentrations of the active pharmaceutical ingredient (API) within the therapeutic window can be challenging with immediate-release (IR) tablets. To avoid the plasma peaks and troughs associated with IR tablets, sustained release (SR) formulations have been investigated. Zeolites are microporous aluminosilicate minerals that represent a novel tabletting material with the potential for modifying drug release due to their unique adsorption and ion exchange properties1. Aim This study will investigate the potential for inclusion of zeolites within orally disintegrating tablets (ODTs) and assessment of their ability to modify API release. Methods In-house, 50%w/w ibuprofen (IBU)-loaded ODTs (IHODTs) were prepared from Pearlitol® Flash, magnesium (Mg) stearate and 2 different zeolites (CP814C and CP814E), incorporated at 5%w/w each, using a manual tablet press. Formulations were prepared and mixed for 10 minutes in a cube mixer prior to direct compression (DC) into tablets. Physical characteristics of the tablets were assessed by hardness and friability measurements. Tablet quality was assessed by disintegration and dissolution analysis to British Pharmacopeia (BP) standards2. Release profiles were assessed against various models to determine the effect of zeolites on the release of IBU. Formulations were further examined and characterised using scanning electron microscopy (SEM) and energy-dispersive x-ray (EDX) spectroscopy. An ethics evaluation was completed, and the study was identified as not having any ethical considerations by the University of South Wales. Results The mean weight of blank ODTs was found to be 225.3mg, with a mean thickness of 3.65mm, diameter of 8.10mm, hardness of 43.9±9.2N (mean±SD, n=5) and friability of 0.2±0.2% (mean±SD, n=3). The hardness of IHODTs was found to be 59.98±1.6N, reducing to 54.9±4.3N and 43.4±0.7N (mean±SD, n=3) with the inclusion of CP814C and CP814E, respectively. The friability of IHODTs containing zeolites was 1.76±0.4% and 1.91±0.9N (mean±SD, n=3), for CP814C and CP814E, respectively; conforming to BP specification2. The disintegration time for all in-house tablets, both with and without a zeolite included, was found to be an order of magnitude greater than commercial ODTs (CT) controls, but all remained within the BP specification2. The release of IBU from IHODTs and CTs showed good correlation to the first-order release model (R2 = 0.96 and 0.98, respectively), indicating IR behaviour. Similarly, the release of IBU from IHODTs containing zeolites was shown to correlate best with the first-order release model, R2 = 0.91 for CP814C and R2 = 0.90 for CP814E, respectively. SEM analysis suggested a homogeneous blend of components within IHODTs, whilst EDX analysis indicated the presence of silicon and aluminium from zeolites, and Mg and carbon from Mg stearate and IBU, respectively. Discussion / Conclusion This study investigated the effect of zeolite inclusion on the release properties of ODTs containing IBU. Although the quality of ODTs containing zeolites was not compromised, this study suggests that inclusion of a zeolite by DC only, does not significantly modify the release profile. Future studies are required to ascertain whether zeolites can achieve SR from ODTs using alternative API loading approaches, such as solvent loading1.

Trajectory Analysis of the Four-Year Changes in Body Composition and Bone Mineral Characteristics Among Highly Competitive Male University Long-Distance Runners.

This study examined long-term changes in body composition and bone mineral characteristics among male long-distance runners from a high-profile university team, focusing on concerns about impaired musculoskeletal development due to extreme leanness and weight management practices in this population. Trajectory analyses were performed using multilevel modeling of 608 dual-energy x-ray absorptiometry datasets from 109 runners (mean age, height, and weight of 18.0 years, 171.4 cm, and 56.8 kg at baseline, respectively) collected biannually over 4 years. Linear increases in total and regional lean mass (LM) were observed on average, with the increase in leg LM being double that of arm LM (0.07 vs. 0.03 kg per occasion, respectively). Similarly, total bone mineral density (BMD) and content (BMC) exhibited linear growth on average, with BMD accrual being greater in the legs than in the arms (0.004 vs. 0.001 g/cm2 per occasion, respectively). However, rib BMD and BMC were predicted to decrease. Individually predicted growth rates in total LM were significantly associated with those in total BMD (r = 0.347, p < 0.001) and BMC (r = 0.424, p < 0.001). These results indicate site-specific musculoskeletal adaptations to intensive long-distance running training. Moreover, a random slope model accurately captured the trajectories of most dependent variables, highlighting the heterogeneity of training responses. The predictive models developed in this study offer practical strategies for identifying runners at risk of suboptimal physical development, thereby facilitating the development of personalized conditioning programs.

The Agreement of Intraocular Pressure Measurement in Healthy Merinos Sheep Using Rebound Tonometer (Tonovet®) and Applanation Tonometer (Tono-Pen VetTM)

The assessment of intraocular pressure (IOP) holds significant importance in ophthalmology as a crucial diagnostic tool for various ocular disorders. In the realm of comparative ophthalmology research, investigating ocular examination in sheep, particularly Merinos, is of considerable interest. This study aimed to evaluate the agreement between rebound (TonoVet®, TV) and applanation (Tono-Pen Vet™, TPV) tonometers in measuring IOP in healthy Merino sheep. 155 healthy Merinos (80 males, 75 females) with a mean weight of 54.4 ± 8.7 kg, aged 24 ± 6 months, were included in the study. IOP was measured between 9:00 and 11:00 am using both the rebound and applanation tonometers. The rebound tonometer was utilized first, followed by the applanation tonometer. A total of 620 readings (310 readings per eye) were obtained from the two devices. No statistical differences were noted between the mean IOP measurements of the right and left eyes for both tonometers (P &gt; 0.05). However, there was a significant difference in the mean IOP measurements between the TV (11.8 ± 2.3 mmHg) and the TPV (13.9 ± 2.9 mmHg) tonometers (P &lt; 0.001). The concordance correlation coefficient indicated weak agreement strength (ρc = 0.319, CI 95% = -0.169 to 0.455) between the TV and TPV. The mean difference in bias and the 95% limits of agreement for the differences between TV and TPV were -2.1 mmHg (-9.0 to 3.5 mmHg). The regression equation derived from a Bland-Altman plot, describing the relationship between the two tonometers, was Y = 1.43 - 0.33X (Y = TV and X = TPV). In conclusion, the TPV measured higher IOP values compared to the TV, and due to the significant bias and limits of agreement, the two tonometers should not be used interchangeably for IOP measurement in Merino sheep.

The Optimal Dosage and Duration of Metformin for Prevention and Treatment of Antipsychotic-Induced Weight Gain: An Updated Systematic Review and Meta-Analysis.

Weight gain and metabolic complications are substantial adverse effects associated with second-generation antipsychotics. However, comprehensive guidelines for managing antipsychotic-induced weight gain are lacking. This review included all double-blind, placebo-controlled studies investigating metformin's effectiveness in addressing antipsychotic-related weight gain. We systematically searched PubMed, Embase, the Cochrane Central Register of Controlled Trials, Google Scholar, and ClinicalTrials.gov for relevant studies from the inception to 2024. A random-effects model was used for the meta-analysis. This meta-analysis, including 20 studies with 1070 patients, revealed that metformin significantly surpassed placebo in attenuating weight gain in patients receiving antipsychotics. The mean weight change with metformin was -3.32kg [95% confidence interval (CI): -4.57 to -2.07]. Additionally, metformin use resulted in a marked decrease in body mass index [-1.24kg/m2 (95% CI: -1.70 to -0.77)]. Metformin could maintain the effects from 12 to 24 weeks. This updated meta-analysis investigated the durations and dosages of metformin use in patients with schizophrenia experiencing antipsychotic-induced weight gain. The findings highlight the need for additional large-scale research to validate our findings.

Effect of Glycated Haemoglobin (HBA1c) on Cardiorespiratory Fitness (CRF) in a Population with Type 2 Diabetes Mellitus (T2DM): A Cross-Sectional Study

Background and Objective: The aim of this study was to evaluate cardiorespiratory fitness (CRF) measures, maximal oxygen consumption (VO2 max), and minute ventilation/carbon dioxide production (VE/VCO2 slope and others) among the T2DM population based on glycated haemoglobin (HBA1c). Material and Methods: The present study comprised a cross-sectional design, with two groups, based on HbA1c values (≤7 and ≥7.1). Laboratory samples were taken to evaluate glycated haemoglobin and fasting blood glucose (FBS). Cardiopulmonary exercise testing was performed to calculate various fitness-related parameters. Data analysis: An independent t-test was used to analyse the outcomes in the two groups. p &lt; 0.05 was considered significant. Linear regression was used to examine the influence of predictor variables on dependent variables. Results: A total of 70 patients agreed to participate in the study, with 19 females and 51 males. The mean (standard deviation) BMI (body mass index) of all participants was 29.7(5.2), the mean (SD) weight was 84.4 (18.9) kg, and the mean height was 167.4 (23) cm. The average age of the individuals was 52 ± 8 years. The independent t-test revealed a significant difference between the two groups in terms of CRF measures. Conclusions: The current research identified the presence of poor glycaemic control and cardiorespiratory fitness measures among the Brazilian population with T2DM. HBA1c, duration of diabetes, age, and BMI can be employed to predict the ventilatory threshold (VT) and VO2 max.

Evaluation of Ethanolic Extract of Red Seaweed (Gracilariopsis lemaneiformis) on Growth and Haematological Parameters of Nile Tilapia (Oreochromis niloticus)

ABSTRACTSeaweed is multicellular marine macroalgae that enhances the immunity of aquatic organisms. The study was designed to assess the ethanolic extract (EtOH) extracted from red seaweed (Gracilariopsis lemaneiformis) on Nile tilapia (Oreochromis niloticus) to evaluate growth, immunity and haematological parameters. The EtOH was applied with fish feed in four treatments such as T1‐control (0% EtOH), T2 (5% w/v EtOH), T3 (10% w/v EtOH) and T4 (15% w/v EtOH) each with three replicates. The initial average weight of the fish was 17.53 ± 2.1 g. Results showed that the growth increased gradually with the percentage of red seaweed extract, whereas the mean weight gain was found significantly higher in T4 (51.5 ± 4.2) than in the control. The specific growth rate (%) and survival rate (%) were found higher in T4 at the lowest FCR compared to other treatments (p &lt; 0.05). The blood haemoglobin level of Nile tilapia was higher in T4 (11.5 g/dL) and lowest recorded in T1 (7.5 g/dL). However, the level of blood glucose interacted inversely with blood haemoglobin. The plasma protein level was also varied among the treatments (p &gt; 0.05). The blood parameters, refractive index (RI) and spleen somatic index (SSI) were significantly different among the treatments. The RI of blood plasma and SSI were found to be better in T4 treatment. The research indicated that red seaweed extracts significantly enhanced the growth and boosted the immunity level of Nile tilapia.
