Systematic review on buparvaquone resistance associated with non-synonymous mutation in drug binding genes site of Theileria annulate.

Theileria annulata (T. annulata) is intra-erythrocytic protozoan parasite which is more prevalent in tropical and sub-tropical countries. It has a significant economic impact on the productivity of the dairy industry, and buparvaquone is used to treat infected animals in the prevalent regions of the world. Systematically, buparvaquone targets the cyto-b gene to break the electron transport chain (ETC) and Theileria annulata peptidyl-prolyl isomerase 1 (TaPIN1) gene to destabilize transcription factor JUN (c-JUN) to inhibit proliferation of infected cells, which ultimately leads to the death of T. annulata. The reported studies on drug resistance is due to inappropriate drug application, evolutionary characteristics of the cytochrome b (cyto-b) gene and oncogenic signaling pathways gene (TaPIN1) make the parasite resistant against buparvaquone. Hence, this systematic review was designed to find out non-synonymous mutation in genes (cyto-b and TaPIN1) responsible for drug resistance reported from Tunisia, Turkey, Egypt, Sudan, Iran, Pakistan, China and Germany with reference to the T. annulata Ankara strain of cyto-b (accession no. XM_949625.1) and TaPIN1 (accession no. TA18945) wild type genes. Non-synonymous point mutations were found in cyto-b (Q01 at 130-148 and Q02 at 253-262 regions) and TaPIN1 (A53P and A53T) genes. These point mutations are responsible for developing buparvaquone resistance against T. annulata infection. These genes can be used as biomarkers for the identification of drug resistance in any endemic area. To avoid the complication of drug resistance, development of genetically resistant cattle breeds, potent vaccines and anti-theilerial drugs (Trifloxystrobin and anti-cancerous) are currently required to control proliferating economically important T. annulata parasites.

Mitral valve repair and replacement in infectious endocarditis: a systematic review and meta-analysis of clinical outcome.

BACKGROUND: Infective endocarditis (IE) poses significant clinical challenges, often necessitating surgical intervention for improved patient outcomes. The choice between mitral valve repair (MVP) and mitral valve replacement (MVR) is crucial in managing IE. This systematic review and meta-analysis aims to compare the effectiveness of MVP and MVR in treating IE, focusing on outcomes such as postoperative bleeding, mortality, recurrent endocarditis, and stroke. MAIN TEXT: A comprehensive literature search was conducted following PRISMA guidelines. Studies directly comparing MVP and MVR in IE patients were included. Data extraction and quality assessment were performed, and meta-analysis was conducted using RevMan software. Thirty-two studies involving 82,123 patients were included. MVP was associated with significantly lower rates of postoperative bleeding (OR: 0.58, 95% CI: 0.40-0.84) and reduced long-term mortality (OR: 0.40, 95% CI: 0.32-0.51) compared to MVR. However, MVR showed lower rates of recurrent endocarditis. MVP was also associated with a decreased likelihood of postoperative stroke (OR: 0.52, 95% CI: 0.40-0.68).2, 4 CONCLUSIONS: MVP demonstrates advantages over MVR in reducing postoperative bleeding, long-term mortality, and stroke risk in IE patients. However, individual patient factors and surgical expertise must be considered in treatment decisions. Further research, including randomized controlled trials, is needed to validate these findings and refine treatment algorithms for IE management.

Exploring customer retention dynamics: A comparative investigation of factors affecting customer retention in the banking sector using mediation-moderation approach.

The purpose of this research is to explore the impact of service quality, customer trust, and cultural disparities on customer satisfaction within the banking sector. Additionally, the study examined the mediating effect of customer satisfaction and the moderating effect of financial technology. Data for this investigation were gathered from customers utilizing services offered by public banks in Pakistan and China. The analysis was conducted using the Smart-PLS software, with 281 samples from Pakistan and 312 samples from China being included in the study. Results show that service quality, customer trust, and cultural differences positively affect customer satisfaction in the context of Pakistan and China. Results also reveal that service quality and customer trust have a positive effect on customer retention behavior in China, but customer trust has an insignificant impact on customer retention behavior in Pakistan. Analysis specifies that customer satisfaction positively mediated the relationship between service quality, customer trust, cultural differences, and customer retention behavior in Pakistan and China. More importantly, financial technology moderated the relationship between customer satisfaction and customer retention behavior, but it was insignificant in the context of China and Pakistan. The study seeks to provide significant insights for strategic decision-making and improve customer relationship management techniques in the dynamic field of financial services by including mediating and moderating elements.

Comparative effectiveness of metabolic and bariatric surgeries: a network meta-analysis.

Bariatric surgery is recommended for patients with unhealthy weight. Our study aim to compare and rank different bariatric surgical approaches in reducing weight parameters. We searched MEDLINE, Cochrane CENTRAL, Scopus, and Web of Science databases from inception to September 2023. We extracted all outcomes as mean change from the baseline. The mean difference and 95% confidence interval were used as a summary measure. All analysis was conducted with R version 4.2.2 (2022-10-31) and R Studio version 2022.07.2 (2009-2022) (RStudio, Inc.). Included surgeries were: Biliopancreatic diversion (BPD-RYGB), Roux-en-Y Gastric Bypass (RYGB), Laparoscopic Gastric Plication (LGP), Duodenal-Jejunal Bypass Sleeve (DJBS), Single-anastomosis gastric bypass (SAGB), Laparoscopic vertical banded gastroplasty (LVBG), Sleeve Gastrectomy (SG), Laparoscopic adjustable gastric banding (LAGB), Gastric plication, Biliopancreatic diversion (BPD), and Intra-gastric balloon (IGB). Only clinical trials were included, with outcomes focused on weight parameters such as reductions in BMI (kg/m²), weight (kg), waist circumference (cm), fat mass (kg), and excess weight loss (EWL) (%). Our analysis of 67 studies showed that SADI-S was the best surgical technique in decreasing BMI (kg/m2) (MD = -18.06; 95% CI [-25.31; -10.81]) and DS follows in efficacy with a P-score (MD = -18.88; 95% CI [-31.15; -6.62]) however the pooled analysis was heterogeneous (I2 = 98.5%). For weight (kg), waist circumference (cm), and fat mass (kg), BPD-RYGB was the best surgical technique to reduce these parameters (MD = -41.48; 95% CI [-47.80, -35.51], MD = -29.08; 95% CI [-37.16, -21.00], and MD = -31.11; 95% CI [-38.77, -23.46]; respectively). The pooled analysis was heterogeneous except in fat mass (I2 = 0%, p-value = 0.8). Our network meta-analysis showed that the best surgical technique in increasing EWL (%) was RY-DS (MD = -61.27; % CI [-91.72; -30.82]) the next one in efficacy according to P-score was LVBG (MD = -59.03; % CI [-84.47; -33.59]). SADI-S is most effective in reducing BMI followed by RYGB. DS was associated with most estimated weight loss %.

Diuretic and Anti-hyperuricemic Effects of Geranyl Acetate in Rats.

BACKGROUND: Geranyl acetate, a compound found in plant oils, has been studied for its potential effects on renal and cardiovascular ailments. OBJECTIVE: This study aimed to investigate the diuretic and anti-hyperuricemic properties of geranyl acetate in male Wistar rats using a hyperuricemia-induced rat model. METHODS: Molecular docking studies were conducted to assess geranyl acetate's interactions with various targets. in vitro studies were performed to evaluate its scavenging ability and inhibition of xanthine oxidase, urease, and acetylcholinesterase. Subsequently, we administered different doses of geranyl acetate (25, 50, and 100 mg/kg) and a reference drug (furosemide) to the rats to assess their acute and repeated dose diuretic effects over seven days. To understand the diuretic mechanism, we used inhibitors, such as L-- NAME, indomethacin, and atropine, prior to administering geranyl acetate. We also tested the anti-hyperuricemic potential of geranyl acetate on hyperuricemic rats. RESULTS: Molecular docking suggested strong binding between geranyl acetate and nitric oxide synthase. in vitro studies showed significant free radical scavenging activity and and inhibition of acetylcholinesterase, xanthine oxidase, and urease. The 100 mg/kg dose exhibited the most promising diuretic effects, with nitric oxide appearing to influence its action. Uric acid excretion increased at this dose, resembling allopurinol effects. CONCLUSION: Geranyl acetate has demonstrated significant diuretic and anti-hyperuricemic effects, likely influenced by nitric oxide release and inhibition of enzymes, like xanthine oxidase and urease. The findings have suggested potential benefits for individuals with kidney ailments, hypertension, and gout.

Kawasaki disease with profound systemic vascular involvements: An insightful pediatric case.

Key Clinical Message: Kawasaki disease (KD), a self-limiting vasculitis, can present with a broader spectrum of vascular involvements, necessitating early recognition and prompt management. This case exemplifies the importance of involving multiple teams on board in managing complex presentations of KD. It also highlights the importance of close monitoring for the progression of the disease spectrum as well as family education to ensure favorable outcomes. The case also emphasizes the importance of long-term follow-up and further research to understand the prognosis, early screening tools, and possible complications due to multi-organ involvement in KD along with their management strategies. Abstract: Kawasaki disease (KD) is a multisystem vascular inflammatory syndrome, which predominantly affects the small and medium vessels in children within the age group of less than 5 years. The most threatened complication is the development of coronary artery aneurysms (CAAs). We present an extremely rare case of KD in a 2-month, 21-day-old male infant with extensive vascular involvement, expanding the disease spectrum beyond the involvement of coronary arteries. These included aneurysmal dilatations of both internal carotid arteries, the descending aorta, bilateral multilevel intercostal arteries, coeliac artery, superior mesenteric artery, and both renal arteries. Implementing a multidisciplinary approach with early treatment via intravenous immunoglobulin (IVIG) and dexamethasone proved to be most effective in the patient's management. Despite unique challenges such as severe coronary dilation and pseudomonas sepsis during the special care, the patient was stabilized and discharged after 11 days of hospital stay, highlighting the importance of early prompt management and a centered approach to evaluate in a broader spectrum. This case emphasizes the importance of long-term follow-up and further research to understand the prognosis, early screening tools, and possible complications due to multi-organ involvement in KD along with their management strategies.

Exploring the hepatoprotective properties of citronellol: In vitro and in silico studies on ethanol-induced damage in HepG2 cells.

Citronellol (CT) is a monoterpene alcohol present in the essential oil of plants of the genus Cymbopogon and exhibits diverse pharmacological activities. The aim of the current study was to investigate the hepatoprotective potential of CT against ethanol-induced toxicity in HepG2 cell lines. Silymarin (SIL) was used as a standard drug. MTT, crystal violet assay, DAPI, and PI staining were carried out to assess the effect of ethanol and CT on cell viability. RT-PCR determined the molecular mechanisms of hepatoprotective action of CT. CT ameliorated cell viability and restricted ethanol-induced cell death. DAPI and PI staining showed distinct differences in cell number and morphology. Less cell viability was observed in the diseased group obviously from strong PI staining when compared to the CT- and SIL-treated group. Moreover, CT showed downregulation of interleukin (IL-6), transforming growth factor-beta 1 (TGF-ß1), collagen type 1 A 1 (COL1A1), matrix metalloproteinase-1 (MMP-1), tissue inhibitor of metalloproteinase-1 (TIMP-1) and glutathione peroxidase-7 (GPX-7) levels. Molecular docking studies supported the biochemical findings. It is concluded that the cytoprotective activity of CT against ethanol-induced toxicity might be explained by its anti-inflammatory, immunomodulatory, and collagen-regulating effects.

Extensive intraoperative peritoneal lavage with surgery, compared to surgery alone, for patients diagnosed with gastric cancer: A systematic review and meta-analysis of randomized controlled trials.

BACKGROUND: Gastric cancer ranks as the fifth most frequently diagnosed cancer and the seventh most prevalent overall. The lifetime risk of developing gastric cancer is 1.87% for males and 0.79% for females worldwide. AIM: This systematic review and meta-analysis aimed to determine whether Extensive Intraoperative Peritoneal Lavage (EIPL) provides short-term benefits or improved survival outcomes for patients undergoing gastrectomy. METHODS: A comprehensive search spanned PubMed, Embase, Cochrane Library, clinicaltrials.gov, and Web of Science, from their inception up to October 2023, adhering to predefined inclusion and exclusion criteria. The quality of the studies was analyzed using the Cochrane Collaboration Risk of Bias Tool. Data analysis was done using Review Manager 5.3, utilizing a random-effects model. RESULTS: Our analysis incorporated seven randomized controlled trials with 2602 patients. The follow-up time for all outcomes varied from 30-60 months. For our primary outcomes, EIPL demonstrated a significant benefit over surgery alone in terms of recurrence (RR=0.73; 95% CI: 0.65 to 0.83, P<0.00001) and postoperative complications (RR=0.67; 95% CI: 0.51 to 0.87, P=0.003). For our secondary outcomes, postoperative hospital stay (MD=-0.35; 95% CI: -1.11 to 0.41; P-value=0.37), 3-year overall survival (OR=1.44; 95% CI 0.84 to 2.47; P-value=0.19), 3-year disease-free survival (HR=0.93; 95% CI: 0.78 to 1.13; P-value=0.48), and time to first flatus (MD=-0.17; 95% CI: -0.35 to 0.01; P-value=0.06), no statistically significant differences were observed between the EIPL and control groups. CONCLUSION: While there is a marginal difference in survival outcomes, EIPL holds promise in significantly reducing overall cancer recurrence and suggests an enhancement in postoperative recovery.

VesiMCNN: Using pre-trained protein language models and multiple window scanning convolutional neural networks to identify vesicular transport proteins.

Vesicular transport is a critical cellular process responsible for the proper organization and functioning of eukaryotic cells. This mechanism relies on specialized vesicles that shuttle macromolecules, such as proteins, across the cellular landscape, a process pivotal to maintaining cellular homeostasis. Disruptions in vesicular transport have been linked to various disease mechanisms, including cancer and neurodegenerative disorders. In this study, we present vesiMCNN, a novel computational approach that integrates pre-trained protein language models with a multi-window scanning convolutional neural network architecture to accurately identify vesicular transport proteins. To the best of our knowledge, this is the first study to leverage the power of pre-trained language models in combination with the multi-window scanning technique for this task. Our method achieved a Matthews Correlation Coefficient (MCC) of 0.558 and an Area Under the Receiver Operating Characteristic (AUC-ROC) of 0.933, outperforming existing state-of-the-art approaches. Additionally, we have curated a comprehensive benchmark dataset for the study of vesicular transport proteins, which can facilitate further research in this field. The remarkable performance of our model, combined with the comprehensive dataset and novel deep learning model, marks a significant advancement in the field of vesicular transport protein research.

Genetic variation and population structure of Taenia multiceps (Coenurus cerebralis) based on mitochondrial cox1 gene: A comprehensive global analysis.

Taenia multiceps is a neglected parasite having veterinary and public health importance. The predilection sites of the parasite larva (Coenurus cerebralis) are brain (cerebral coenurosis) and subcutaneous (non-cerebral coenurosis). There is a dearth of data regarding molecular characterization of T. multiceps and even fewer population structure-based studies on T. multiceps. The current study was conducted to provide epidemiological information regarding the global population structure of the parasite. The NCBI GenBank database was accessed to download the sequences of cox1 gene, which were further subjected to PopArt software to construct median-joining networks. The DnaSp software was used to compute neutrality and diversity indices. Host and region-wise indices of neutrality and diversity were also computed. There were 166 gene sequences found in the NCBI database. Followed by removal of short gene sequences, 143 were considered to perform bioinformatic analyses. A total of 30 haplotypes with 46 mutations and 23 parsimony informative sites were found. High diversity (Hd = 0.889, π = 0.01186) and negative but statistically insignificant neutrality indices (Tajima's D = -1.57659, Fu's Fs = -10.552) were found. Region-wise results revealed highest haplotype diversities in isolates from KSA (Hd = 1.00) followed by Greece and Italy (Hd = 0.962), and China (Hd = 0.931). Host-wise data analysis showed an overall negative Tajima's D value and there exists highest haplotype diversity in cattle (Hd = 1.00) followed by dogs (Hd = 0.833), sheep (Hd = 0.795) and goats (Hd = 0.788). The findings of the study indicate that the population diversity of T. multiceps will increase worldwide as shown by high diversity and negative neutrality indices. The findings of the study significantly add-in to the existing bank of knowledge about population structure of T. multiceps. We recommend conducting more studies employing different genetic markers to better comprehend the epidemiology of the parasite.

Enhancement in the antibacterial activity of Rifaximin by delivery through gelatin nanoparticles.

OBJECTIVES: Bacterial infections are a noteworthy global health concern that necessitates the development of new strategies to enhance the potency and efficacy of antibiotics. Rifaximin (RFX), a broad-spectrum antibiotic, exhibits promising antibacterial activity against several bacterial strains. However, its insolubility and impermeability impede the exploitation of its full potential. The objective of the current study is to overcome the inherent caveats of RFX to exploit its maximum potential. SIGNIFICANCE: The exploitation of the full potential of antibiotics is necessary for reduction in their dosage and to minimize antibiotic pollution. This is a preliminary study aiming for maximum utilization of RFX at the target site and reduction in its release in unmetabolized form. METHODS: Gelatin is a biopolymer that has gained significant attention for biomedical applications owing to its inherent biocompatibility and biodegradability. In this study, bovine gelatin nanoparticles (BGNPs) were fabricated by the self-assembly method for their application as a carrier of RFX to enhance its antibacterial activity. The study employs a comprehensive range of experimental techniques to characterize the fabricated BGNPs such as DLS, Zeta Potential, FT-IR, AFM, SEM-EDX, and UV-Vis spectrophotometry. RESULTS: The average size of the fabricated BGNPs was 100 nm with a zeta potential value of -15.3 mV. The loading of RFX on BGNPs rendered an increase in its size to 136 nm with a zeta potential value of -16 mV. In-vitro assays and microscopic analyses were conducted to compare the antibacterial efficacy of RFX and RFX@BGNPs. An excellent loading capacity followed by sustained release of RFX from RFX@BGNPs rendered a significant enhancement in its pharmaceutical efficacy. The release of RFX from RFX@BGNPs followed the Higuchi and Korsmeyer-Peppas models. The antibacterial efficacy of RFX against Staphylococcus aureus has doubled by delivery through RFX@BGNPs, assessed by inhibitory and biofilm inhibitory assays. The enhancement in the antibacterial efficiency was further endorsed by SEM and microscopic imaging of the control and treated bacterial colonies. CONCLUSION: The study demonstrates an enhancement in the antimicrobial efficacy of RFX by its delivery in the form of RFX@BGNPs to exploit its full potential for practical applications.

Thriving among Pakistani physicians: A qualitative study.

OBJECTIVE: Burnout among physicians negatively impacts the quality of patient care and provider's mental health. While many studies have evaluated burnout, factors associated with physician thriving are not well-defined. This study involved a qualitative exploration of thriving and career satisfaction among physicians in Pakistan. METHODS: A snowball sampling technique was used to recruit participants who completed a measure of job satisfaction, life satisfaction, and burnout between December 2022 and February 2023. Semi-structured interviews were conducted to explore factors associated with burnout and thriving. Participants were physicians working in public and private hospitals in North Punjab. RESULTS: Twenty-four physicians were interviewed. Six themes emerged that might help to explain factors involved in thriving: patient's affirmation, serving humanity, social support, spiritual connection, occupational prestige, and activities outside of work. Two themes were identified as challenges to thriving: excessive workload and lack of resources. CONCLUSION: Improving the well-being of primary care practitioners requires a multi-modal approach, which includes cultivating intrinsic virtues, such as resilience and spiritual resources, as well as improving social support and the workplace environment.

Genetic diversity and population structure of Echinococcus multilocularis: An in-silico global analysis.

Objective: Alveolar echinococcosis is caused by Echinococcus multilocularis, a parasite of zoonotic significance with a wide range of intermediate and final hosts, and the parasite survives successfully in diversified conditions. Plentiful studies have been done to study the genetic structure of the population of the parasite and the level of intimate kinship using mitochondrial (mt) DNA. The present study was conducted to investigate the population structure, genetic variation, and phylogenetic relationship of various isolates of E. multiocularis submitted to GenBank worldwide. Sequences of mt genes (mt-cytochrome c oxidase (cox1), mt-NADH dehydrogenase (nad1)) of E. multilocularis were analyzed to achieve the set goals. Materials and Methods: A total of 275 and 124 gene sequences of mt-cox1 and mt-nad1 belonging to E. multilocularis, respectively, were retrieved from the National Center for Biotechnology Information GenBank. The retrieved sequences were subjected to alignment with respective reference sequences using MEGA software. The PopArt software was used to establish median-joining networks, while DnaSp was used to calculate neutrality and diversity indices. MrBayes software was used to investigate the phylogenetic association between haplotypes based on Bayesian phylogeny. Results: Approximately 13 and 20 distinctive haplotypes of nad1 and cox1 genes, respectively, were observed in the present study. In both of the mt genes, diversity indices indicated low haplotype (mt-cox1 = 0.140; mt-nad1 = 0.374) and nucleotide (mt-cox1 = 0.00111; mt-nad1 = 0.00287) diversities. The values of Tajima's D and Fu Fs for a population of both of the genes under study were found to be negative. Conclusion: This study is a maiden attempt to provide insights into the population structure and genetic variation of E. multilocularis on a global scale. However, it is suggested that to better understand the population structure and genetic diversity of E. multilocularis, more geographical locations and amplifications of full-length gene sequences should be considered, which could be helpful in widening the insights into the genetic diversity of E. multilocularis.

Food temperature altered macronutrients induced changes in satiety hormones; glucagon - like peptide -1 and cholecystokinin and their correlation with subjective satiety.

BACKGROUND: The benefits of dietary macronutrients for weight management depend on the integrity of gut hormones. The role of food temperature in the release of satiety hormones and satiety needs elucidation. We aimed to determine the impact of different food temperatures with varying macronutrient compositions on satiety-related gut hormones glucagon-like peptide-1 (GLP-1) and cholecystokinin (CCK) and find the correlation of satiety hormones with appetite scores and remainder-day food (energy) intake. MATERIALS AND METHODS: Thirteen healthy participants (eight males and five females) aged 25-35 years with body mass index 18.5-24.9 kg/m2 with no medical illnesses or eating disorders consumed three compositions of meals (high carbohydrate, high fat, and high protein meals) each at three temperatures (cold, warm, and hot) in a randomized, double-blinded, controlled crossover design. Plasma concentrations of peptide hormones were determined at 0, 30, and 240 minutes by enzyme-linked immunosorbent assay, and 24-hours food recall was used for remainder-day food intake (remainder energy). Data were analyzed using SPSS version 27.0. The change in plasma levels of gut hormones with time was assessed using Friedman test; Kruskal-Wallis test was employed to compare GLP-1 and CCK hormonal levels across nine meals. RESULTS: A comparison of the three meals at the three temperatures (total of nine groups), showed that the GLP-1 and CCK plasma concentrations were significantly different (P < 0.001). GLP-1 and CCK responses increased more after hot meals than cold meals. Overall, high-fat meals had more effective gut hormone secretions. The area under the curve was increased for GLP-1 in high-fat meals and for CCK in hot meals. The peptide hormones (GLP-1 and CCK) were positively correlated with satiety scores and inversely with remainder food intake. CONCLUSION: The temperature of food was found to be an effective stimulus for the regulation of CCK and GLP-1 secretion. Hot food temperature increased satiety hormones (CCK and GLP-1), independent of food macronutrient composition.

Effects of betaine supplementation on dry matter intake, milk characteristics, plasma non-esterified fatty acids, and ß-hydroxybutyric acid in dairy cattle: a meta-analysis.

Betaine supplementation in dairy cattle has gained attention due to its potential benefits to production and health as a methyl donor, which can play a crucial role in the metabolism of dairy cows. The objective of the current meta-analysis was to quantify the effects of betaine supplementation on milk production, composition, ß-hydroxybutyric acid (BHBA), and non-esterified fatty acids (NEFA). A systematic literature search was carried out, all relevant studies were retrieved, and the meta-analysis was carried out. The mean difference (MD) for dry matter intake (DMI) using the random-effects model was 0.499 kg/d (P < 0.0001). The subgroup analysis indicated that supplementing betaine in heat-stressed cows increased DMI by 0.584 kg/d (P < 0.001), while in cows not exposed to heat stress, DMI was increased by 0.381 kg/d (P = 0.007). The energy-corrected milk (ECM) increased by 1.36 kg/d (P < 0.0001). The milk fat yield was significantly increased in betaine-supplemented cows (MD = 0.040 kg/d, 95% CI = 0.015 to 0.065). The milk protein yield (kg/d) (MD = 0.014, P = 0.138) was increased (MD = 0.035, P = 0.0005) by betaine supplementation. The lactose yield (kg/d) was also significantly higher (MD = 0.055, P = 0.020) in betaine-supplemented cows. The standardized mean difference (SMD) for NEFA (SMD = - 0.447, 95% CI = - 1.029 to 0.135, P = 0.114) and BHBA (SMD = - 0.130, 95% CI = - 0.491 to 0.234). In conclusion, the findings from this meta-analysis suggest that betaine supplementation positively influences DMI, ECM, milk fat yield, milk lactose yield, and milk protein yield. Subgroup analysis further indicated that the positive effects on DMI are greater in heat-stressed cows compared to those not exposed to heat stress. The analysis did not find significant effects on the levels of NEFA or BHBA, suggesting that betaine supplementation may not directly influence these metabolic parameters.

The aim of this meta-analysis was to examine the effects of dietary betaine supplementation on dairy cows' dry matter intake, milk production, milk composition, non-esterified fatty acids, and ß-hydroxybutyric acid. The results indicated that the supplementation of betaine increased dry matter intake (+0.584 kg/d/cow), energy-corrected milk (+1.36 kg/d), milk fat yield (+ 0.040 kg/d), milk protein yield (+ 0.014 kg/d), and lactose yield (+ 0.055 kg/d). ß-Hydroxybutyric acid and plasma non-esterified fatty acids were not influenced by betaine supplementation in dairy cattle.

Three layered sparse dictionary learning algorithm for enhancing the subject wise segregation of brain networks.

Independent component analysis (ICA) and dictionary learning (DL) are the most successful blind source separation (BSS) methods for functional magnetic resonance imaging (fMRI) data analysis. However, ICA to higher and DL to lower extent may suffer from performance degradation by the presence of anomalous observations in the recovered time courses (TCs) and high overlaps among spatial maps (SMs). This paper addressed both problems using a novel three-layered sparse DL (TLSDL) algorithm that incorporated prior information in the dictionary update process and recovered full-rank outlier-free TCs from highly corrupted measurements. The associated sequential DL model involved factorizing each subject's data into a multi-subject (MS) dictionary and MS sparse code while imposing a low-rank and a sparse matrix decomposition restriction on the dictionary matrix. It is derived by solving three layers of feature extraction and component estimation. The first and second layers captured brain regions with low and moderate spatial overlaps, respectively. The third layer that segregated regions with significant spatial overlaps solved a sequence of vector decomposition problems using the proximal alternating linearized minimization (PALM) method and solved a decomposition restriction using the alternating directions method (ALM). It learned outlier-free dynamics that integrate spatiotemporal diversities across brains and external information. It differs from existing DL methods owing to its unique optimization model, which incorporates prior knowledge, subject-wise/multi-subject representation matrices, and outlier handling. The TLSDL algorithm was compared with existing dictionary learning algorithms using experimental and synthetic fMRI datasets to verify its performance. Overall, the mean correlation value was found to be 26 % higher for the TLSDL than for the state-of-the-art subject-wise sequential DL (swsDL) technique.

Relationship between sarcopenia and metabolic dysfunction-associated steatotic liver disease (MASLD): A systematic review and meta-analysis.

INTRODUCTION AND OBJECTIVES: Metabolic dysfunction-associated steatotic liver disease (MASLD) formerly known as Nonalcoholic fatty liver disease (NAFLD) is a common chronic disease. Identifying MASLD risk factors could help early intervention and reduce the burden of the disease. Previous studies investigated the association between sarcopenia and NAFLD. Several trials were published after the last meta-analysis with indecisive results. This is an updated meta-analysis which aims to assess the association between sarcopenia, MASLD, and MASLD-related fibrosis. MATERIALS AND METHODS: Relevant trials published on PubMed, Web of Science, Scopus, and Cochrane Library databases until October 2022 were included. We included studies in which skeletal mass index (SMI) or sarcopenia was compared between patients with and without NAFLD now MASLD. Also, studies comparing fibrosis between MASLD patients with and without sarcopenia were included. Data were pooled as odds ratios (ORs) and 95 % confidence intervals (CIs) using Review Manager Software. RESULTS: A total of 25 studies were included. The incidence of sarcopenia was significantly higher in MASLD than controls (OR, 1.25; 95 % CI, 1.08-1.44; P = 0.003). SMI odds showed no significant difference between MASLD patients and controls (OR, 1.02; 95 % CI, 0.91-1.15; P = 0.7). MASLD patients with sarcopenia had higher odds of fibrosis than MASLD patients without sarcopenia (OR, 1.49; 95 % CI, 1.03-2.14; P = 0.03). CONCLUSIONS: Sarcopenia increased MASLD's probability and was associated with a higher probability of liver fibrosis in MASLD patients. However, SMI had no predictive value of MASLD occurrence.
