We previously reported that high levels (≥50%) of black soldier fly larvae meal (BSFLM) reduced growth and altered organs morphology in broiler chickens. Herein we further examined gastrointestinal, breast, bone, plasma, and litter attributes in broiler chickens fed partial to complete replacement of soybean meal (SBM) with BSFLM. A total of 1152 day-old Ross × Ross 708 male chicks ( n = 8) were allocated to 48 pens and assigned one of six diets: a basal corn-SBM diet (0BSFLM), four diets in which SBM in 0BSFLM was replaced with BSFLM at 12.5%, 25%, 50%, and 100% (12.5BSFLM, 25BSFLM, 50BSFLM, and 100BSFLM) and a final diet (0 + AGP) in which 0BSFLM was fed with coccidiostat and antibiotic. Birds were bled for plasma and necropsied for samples. Litter samples were collected on days 45 to 47. Breast weight, woody breast, and hardness scores and tibia morphometry reduced linearly in response to BSFLM inclusion ( P < 0.001). BSFLM linearly increased plasma Lys, Met, Thr, uric acid, creatine kinase and decreased Arg and potassium ( P < 0.05). Litter ammonium nitrogen and potassium decreased linearly in response to BSFLM ( P < 0.001). In conclusion, the data suggested physiological and metabolic inefficiencies in broiler chickens fed isocaloric and isonitrogenous diets with ≥50% BSFLM replacement of SBM.

Abstract Background: Precision medicine has the potential to improve cardiovascular disease (CVD) risk prediction in individuals with type 2 diabetes (T2D). Methods: We conducted a systematic review and meta-analysis of longitudinal studies to identify potentially novel prognostic factors that may improve CVD risk prediction in T2D. Out of 9380 studies identified, 416 studies met inclusion criteria. Outcomes were reported for 321 biomarker studies, 48 genetic marker studies, and 47 risk score/model studies. Results: Out of all evaluated biomarkers, only 13 showed improvement in prediction performance. Results of pooled meta-analyses, non-pooled analyses, and assessments of improvement in prediction performance and risk of bias, yielded the highest predictive utility for N-terminal pro b-type natriuretic peptide (NT-proBNP) (high-evidence), troponin-T (TnT) (moderate-evidence), triglyceride-glucose (TyG) index (moderate-evidence), Genetic Risk Score for Coronary Heart Disease (GRS-CHD) (moderate-evidence); moderate predictive utility for coronary computed tomography angiography (low-evidence), single-photon emission computed tomography (low-evidence), pulse wave velocity (moderate-evidence); and low predictive utility for C-reactive protein (moderate-evidence), coronary artery calcium score (low-evidence), galectin-3 (low-evidence), troponin-I (low-evidence), carotid plaque (low-evidence), and growth differentiation factor-15 (low-evidence). Risk scores showed modest discrimination on internal validation, with lower performance on external validation. Conclusions: Despite high interest in this topic, very few studies conducted rigorous analyses to demonstrate incremental predictive utility beyond established CVD risk factors for T2D. The most promising markers identified were NT-proBNP, TnT, TyG and GRS-CHD, with the highest strength of evidence for NT-proBNP. Further research is needed to determine their clinical utility in risk stratification and management of CVD in T2D.

A young male labourer developed pain at the site of blunt trauma over back of chest followed by fever, cough with expectoration, breathlessness and hemorrhagic pleural effusion in the side of injury. What could have been passed as a sequel of trauma turned out to be the consequences of an underlying rare and aggressive malignant tumor of the chest wall known as Askin tumor or Primitive Neuroectodermal Tumor (PNET). CT thorax with guided FNAC, debulking operation, histopathological examination followed by immunohistochemistry of the tumor tissue led to the final diagnosis. Chemotherapy was administered following surgical resection. The patient died within nine months after diagnosis.

Mutations of the SQSTM1/p62 gene are commonly observed in PDB. Screening an updated sample from Quebec and using previously published data from other populations, we compared frequency estimates for SQSTM1/p62 mutations and haplotype distribution. The P392L mutation was the most prevalent, embedded in two different haplotypes, possibly shared by other populations. We also examined the phenotype and penetrance of P392L. There is accumulating evidence that supports a contribution of genetic factors in the etiology of Paget's disease of bone (PDB), and several genetic loci have been suggested for the disorder. The sequestosome1/p62 (SQSTM1/p62) gene was the first gene identified to have a role in PDB, with 14 mutations reported to date. To evaluate the importance of the SQSTM1/p62 mutations in PDB, we recruited, sequenced, and genotyped a total of 123 carriers from 20 families in addition to 214 unrelated PDB patients. We compared the frequency of SQSTM1/p62 mutations in familial and unrelated cases among different populations. Finally, we examined the phenotypic expression and penetrance of the P392L mutation in the Quebecois families. The 14 mutations reported in SQSTM1/p62 all affect the ubiquitin-associated domain of the protein. The P392L mutation is the most commonly observed mutation in PDB patients and was consistently found in unrelated and familial PDB cases in the populations tested. Analysis of adjacent polymorphisms suggests that P392L is associated with two different haplotypes in the Quebecois patients, similar to what has been observed in European populations. In Quebec, both haplotypes had similar frequencies in unrelated P392L carriers, whereas one haplotype was predominant in the other populations studied. These data suggest that these two haplotypes, possibly introduced by European founders in the Quebecois population, were equally distributed in the succeeding generations. Finally, the P392L mutation is transmitted as an autosomal dominant trait in the Quebecois families, with a high but incomplete penetrance peaking after age 60. The large phenotypic variability and similarity between unrelated and familial cases, respectively, remain unexplained and require further research.

Europe has long provided bus lanes and on-street bus priority measures.High Occupancy Vehicle (HOV) programs expand that practice to include private shared-ride vehicles (carpools) and other priority vehicles.There are a few HOV lanes in operation in Europe, and interest is growing in their potential applicability in congested urban roadways.With over 200 HOV lane projects now in use on streets and highways around the world, there are useful lessons to be learned by those considering the HOV option in the European context.The reasons for project successes and failures are outlined, with particular attention paid to the constraints and operational issues prevalent in the European environment.Critical issues such as enforcement, conversion from general purpose use, design, and underutilization are explored.The documented effectiveness of HOV facilities in influencing mode choice is summarized.Finally, the future of HOV priority within the urban transport system is discussed, touching on high-tech enforcement solutions, HOV priority within tolled facilities, and the integration of HOV initiatives within broader Transportation Demand Management programmes.

In monkeys, long-term strontium ranelate administration results in a dose-dependent bone strontium uptake (mainly into newly formed bone) that preserves the degree of mineralization of bone and the bone mineral at the crystal level, showing its safety at bone mineral level. Strontium ranelate simultaneously increases bone formation and decreases bone resorption, leading to prevention of bone loss and increase in bone mass and bone strength in normal and ovariectomized rats. This study investigated the interactions of stable strontium (Sr) with bone mineral in monkeys after long-term strontium ranelate treatment and after a period of treatment withdrawal. Iliac bone was obtained from untreated monkeys, monkeys at the end of a 52-week strontium ranelate administration (200, 500, 1250 mg/kg/day orally), and in parallel groups 10 weeks after the end of strontium ranelate administration (same three doses; n = 3-7). Sr uptake and distribution in bone mineral were quantified by X-ray microanalysis, changes at the crystal level by X-ray diffraction, and the degree of mineralization of bone (DMB) by quantitative microradiography. After strontium ranelate administration, dose-dependent Sr uptake occurred into cortical and cancellous bone, with higher content (1.6 times) in new than in old bone. This Sr uptake decreased (50%) 10 weeks after treatment withdrawal; the decrease occurred almost exclusively in new bone. At the end of strontium ranelate treatment and after its withdrawal, a preservation of crystal characteristics was observed, suggesting that Sr was only faintly linked to crystals by ionic substitution and of DMB. These results show the absence of a deleterious effect of long-term strontium ranelate treatment on bone mineralization, confirming the histomorphometric observations made in postmenopausal osteoporotic women treated with strontium ranelate.
