Caffeine-Containing Energy Shots Cause Acute Impaired Glucoregulation in Adolescents

Caffeine-containing, nutritionally fortified energy shots are consumed at high rates by adolescents, yet little is known about their metabolic impact. The purpose of this study was to examine the consequences of small format, caffeinated energy shots on glucose metabolism and gastrointestinal hormone secretion in adolescents. Twenty participants aged 13–19 years participated in a double-blind, randomized cross-over study consisting of two trials separated by 1–4 weeks. Participants consumed a volume-matched caffeinated energy shot (CAF, 5 mg/kg) or a decaffeinated energy shot (DECAF) followed by a 2 h oral glucose tolerance test. Blood samples were collected and area under the curve (AUC) calculated for glucose, insulin and gut and metabolic hormones. Consumption of CAF resulted in a 25% increase in glucose and a 26% increase in insulin area under the curve (AUC, p = 0.037; p < 0.0001) compared to DECAF. No impact on gut hormones was observed. To further characterize responses, individuals were classified as either slow or fast caffeine metabolizers based on an allele score. Glucose intolerance was greater in genetically fast vs. slow caffeine metabolizers and differences between groups were supported by distinct serum metabolomics separation. Consumption of caffeine-containing energy shots results in acute impaired glucoregulation in healthy adolescents as characterized by hyperinsulinemia following an oral glucose challenge.
Various Aspects of a Gene Editing System—CRISPR–Cas9

The discovery of clustered, regularly interspaced short palindromic repeats (CRISPR) and their cooperation with CRISPR-associated (Cas) genes is one of the greatest advances of the century and has marked their application as a powerful genome engineering tool. The CRISPR–Cas system was discovered as a part of the adaptive immune system in bacteria and archaea to defend from plasmids and phages. CRISPR has been found to be an advanced alternative to zinc-finger nucleases (ZFN) and transcription activator-like effector nucleases (TALEN) for gene editing and regulation, as the CRISPR–Cas9 protein remains the same for various gene targets and just a short guide RNA sequence needs to be altered to redirect the site-specific cleavage. Due to its high efficiency and precision, the Cas9 protein derived from the type II CRISPR system has been found to have applications in many fields of science. Although CRISPR–Cas9 allows easy genome editing and has a number of benefits, we should not ignore the important ethical and biosafety issues. Moreover, any tool that has great potential and offers significant capabilities carries a level of risk of being used for non-legal purposes. In this review, we present a brief history and mechanism of the CRISPR–Cas9 system. We also describe on the applications of this technology in gene regulation and genome editing; the treatment of cancer and other diseases; and limitations and concerns of the use of CRISPR–Cas9.
An observational retrospective study of odontogenic cyst´s and tumours over an 18-year period in a Portuguese population according to the new WHO Head and Neck Tumour classification

Background Odontogenic cysts and tumours of the jaws represent one of the most prevalent groups of oral-maxillofacial lesions. We aimed to evaluate the clinical and pathological characteristics of a cohort of odontogenic cysts (OC) and odontogenic tumours (OT) of the jaws in a Portuguese population. Material and Methods This observational retrospective study analysed patients diagnosed with either an OC or OT of the jaws at a central hospital of Oporto, Portugal, between 1988 and 2006. Data collected from patients’ files included demographic, clinical, radiological and histopathological information. Recurrence was evaluated using univariate and multivariate analysis. Results The sample consisted of 397 patients, 231 males (58.2%) and 166 females (41.8%), with a mean-age of 36.7±17 years. Twenty-seven patients (6.8%) presented with more than one lesion providing a total of 433 lesions. There were 396 (91.5%) OC, mostly represented by radicular cysts (n=257;59.4%), dentigerous cysts (n=79;18.2%), or odontogenic keratocysts (n=50;11.5%). There were 37 (8.5%) OT, mostly represented by ameloblastomas (n=16;3.7%), and odontomas (n=9;2.1%). The most common initial clinical manifestation was swelling (n=224;51.7%). Recurrence was observed in 30 cases (6.9%), mostly in ameloblastomas (n=6;37.5%) and odontogenic keratocysts (n=12;24%). In the multivariate analysis the diagnosis classification of the lesion was the only independent and significant variable related with the recurrence (P=0.04). Conclusions Radicular cysts were the most commonly occurring type of OC and ameloblastomas the most commonly occurring OT. Amelobastomas and odontogenic keratocysts were the lesions with the highest rates of recurrence. This large sample provides useful information about the frequency profile and characteristics of OC and OT over a period of 18 years, allowing valuable comparison with data from other countries. Key words:Odontogenic cysts and tumours, radicular cyst, dentigerous cyst, odontogenic keratocyst, ameloblastoma, recurrence.
Novel Medicine for Endometriosis and Its Therapeutic Effect in a Mouse Model

Current therapeutic medicines for endometriosis cannot be administered during assisted reproductive technology (ART) because they have bad effects during pregnancy. In this study, we created an animal model of endometriosis and evaluated the therapeutic effect of progestin (Dienogest), dopamine agonist (Cabergoline), and their combination (Dienogest + Cabergoline). We established a mouse model mimicking human endometriosis. The mice with endometriosis were then treated with a single drug (Dienogest or Cabergoline) or both drugs (Dienogest + Cabergoline) for 14 days. An immunohistological study was then performed to analyze inflammatory lesions in the recipient mice. Real-time polymerase chain reaction (RT-PCR) and Western blotting were also performed to determine the levels of genes and proteins in inflammatory lesions to assess the recovery of endometriosis. Histologic staining showed that all medication groups showed a clear decrease in the inflammatory phenotype in the uterus, peritoneum, and intestine. Gene and protein expression analysis showed a therapeutic effect in all medication groups. In conclusion, Cabergoline had a therapeutic effect similar to that of Dienogest and could be used as an alternative to Dienogest during ART for patients with infertility; compared to the individual drugs, the combination treatment has a synergistic effect on endometriosis.
The Prognostic Impact of Circulating Tumour DNA in Melanoma Patients Treated with Systemic Therapies—Beyond BRAF Mutant Detection

Simple Summary Circulating tumour DNA (ctDNA) has been shown to be an informative biomarker in melanoma. Here we analysed plasma ctDNA in a real-world metastatic melanoma cohort. We found the kinetics of ctDNA decline are delayed in patients treated with immunotherapy compared to those receiving MAPK inhibitors. Nonetheless, decreasing ctDNA levels within 12 weeks of immunotherapy or BRAF/MEK inhibitors was strongly concordant with treatment response and significantly associated with longer progression-free survival (PFS). Furthermore, exploratory analysis of nine patients commencing anti-PD-1 therapy showed a trend of high tumour mutational burden and neoepitope load in responders compared to non-responders. The results support the use of ctDNA as a dynamic biomarker for assessment of response in melanoma patients. Abstract In this study, we evaluated the predictive value of circulating tumour DNA (ctDNA) to inform therapeutic outcomes in metastatic melanoma patients receiving systemic therapies. We analysed 142 plasma samples from metastatic melanoma patients prior to commencement of systemic therapy: 70 were treated with BRAF/MEK inhibitors and 72 with immunotherapies. Patient-specific droplet digital polymerase chain reaction assays were designed for ctDNA detection. Plasma ctDNA was detected in 56% of patients prior to first-line anti-PD1 and/or anti-CTLA-4 treatment. The detection rate in the immunotherapy cohort was comparably lower than those with BRAF inhibitors (76%, p = 0.0149). Decreasing ctDNA levels within 12 weeks of treatment was strongly concordant with treatment response (Cohen’s k = 0.798, p < 0.001) and predictive of longer progression free survival. Notably, a slower kinetic of ctDNA decline was observed in patients treated with immunotherapy compared to those on BRAF/MEK inhibitors. Whole exome sequencing of ctDNA was also conducted in 9 patients commencing anti-PD-1 therapy to derive tumour mutational burden (TMB) and neoepitope load measurements. The results showed a trend of high TMB and neoepitope load in responders compared to non-responders. Overall, our data suggest that changes in ctDNA can serve as an early indicator of outcomes in metastatic melanoma patients treated with systemic therapies and therefore may serve as a tool to guide treatment decisions.
Impacts of Bovine Trace Mineral Supplementation on Maternal and Offspring Production and Health

Simple Summary The objective of this review is to address the importance of trace minerals in maternal and offspring health and production. Several specific trace minerals are discussed in the review, but many trace minerals are lacking research in the area of health, more specifically, maternal trace mineral impacts on offspring health. Much of the research focuses on production and growth and there is limited information regarding the impacts of maternal trace mineral supplementation and offspring health. Selenium, copper, zinc, and manganese have been researched more readily than others, such as cobalt and iron, which have had minimal research conducted. Abstract Nutritional status can have major implications for animal health and production. Energy balance is easily determined using a body condition scoring system. This allows producers to readily adjust diets to meet an animal’s needs. Far less obvious is an animal’s trace mineral status, which is typically not assessed until an animal’s performance falls below expectation or illness is detected. Trace mineral toxicities and deficiencies can manifest as reduced thriftiness and/or poor reproductive performance, resulting in economic consequences for producers. Maternal mineral status not only impacts dam heath, but also the health of subsequent offspring. Both the oocyte and embryo are susceptible to changes in maternal mineral status. This susceptibility is maintained throughout fetal development via placental control of nutrient transfer to the fetal system. Furthermore, maternal mineral status continues to impact offspring health via colostrum and milk quality. Herein we discuss the roles of trace minerals in bovine reproductive performance, maternal health, colostrum and milk quality, and offspring health.
Characterizing Natural Recovery after Traumatic Spinal Cord Injury.

The predominant tool used to predict outcomes after traumatic spinal cord injury (SCI) is the International Standards for Neurological Classification of Spinal Cord Injury (ISNCSCI), in association with the American Spinal Injury Association (ASIA) Impairment Scale (AIS). These measures have evolved based on analyses of large amounts of longitudinal neurologic recovery data published in numerous separate studies. This article reviews and synthesizes published data on neurological recovery from multiple sources, only utilizing data in which the sacral sparing definition was applied for determination of completeness. Conversion from a complete to incomplete injury is more common in tetraplegia than paraplegia. The majority of AIS conversion and motor recovery occurs within the first 6-9 months, with the most rapid rate of motor recovery occurring in the first 3 months after injury. Motor score changes, as well as recovery of motor levels, are described with the initial strength of muscles as well as the levels of the motor ZPP influencing the prognosis. Motor recovery is greater for patients with initial AIS B than AIS A and greater after initial AIS C than with motor complete injuries. Older age has a negative impact on neurological and functional recovery after SCI; however, the specific age (whether > 50 or > 65 years) and underlying reasons for this impact are unclear. Penetrating injury is more likely to lead to a classification of a neurological complete injury as compared with blunt trauma and reduces the likelihood of AIS conversion at 1 year. There is insufficient data to support gender having a major effect on neurological recovery after SCI.
Multimodal imaging improves brain age prediction and reveals distinct abnormalities in patients with psychiatric and neurological disorders

Abstract The deviation between chronological age and age predicted using brain MRI is a putative marker of overall brain health. Age prediction based on structural MRI data shows high accuracy in common brain disorders. However, brain aging is complex and heterogenous, both in terms of individual differences and the underlying biological processes. Here, we implemented a multimodal model to estimate brain age using different combinations of cortical area, thickness and sub‐cortical volumes, cortical and subcortical T1/T2‐weighted ratios, and cerebral blood flow (CBF) based on arterial spin labeling. For each of the 11 models we assessed the age prediction accuracy in healthy controls (HC, n = 750) and compared the obtained brain age gaps (BAGs) between age‐matched subsets of HC and patients with Alzheimer's disease (AD, n = 54), mild (MCI, n = 90) and subjective (SCI, n = 56) cognitive impairment, schizophrenia spectrum (SZ, n = 159) and bipolar disorder (BD, n = 135). We found highest age prediction accuracy in HC when integrating all modalities. Furthermore, two‐group case–control classifications revealed highest accuracy for AD using global T1‐weighted BAG, while MCI, SCI, BD and SZ showed strongest effects in CBF‐based BAGs. Combining multiple MRI modalities improves brain age prediction and reveals distinct deviations in patients with psychiatric and neurological disorders. The multimodal BAG was most accurate in predicting age in HC, while group differences between patients and HC were often larger for BAGs based on single modalities. These findings indicate that multidimensional neuroimaging of patients may provide a brain‐based mapping of overlapping and distinct pathophysiology in common disorders.
Effects of Konjac, Isolated Soy Protein, and Egg Albumin on Quality Properties of Semi-dried Chicken Jerky

The objective of this study was to examine the effect of adding various humectants (konjac, egg albumin, and isolated soy protein) on the properties of semi-dried chicken jerky. Jerky samples were prepared as follows: control with no humectants and treatments with 0.05, 0.1, and 0.2% of added humectants. Adding the humectants influenced the increase in pH, processing yields, moisture contents, water activity, mechanical tenderness, and sensorial properties (tenderness, juiciness, and overall acceptability) of chicken jerky. Additionally, the konjac treatment most improved the yields, tenderness, and sensorial traits, among the humectant treatments tested. Furthermore, adding 0.1% konjac during jerky manufacture resulted in similar quality properties as adding 0.2% konjac.
Randomized Clinical Trial of Inreach With or Without Mailed Outreach to Promote Hepatitis C Screening in a Difficult-to-Reach Patient Population

INTRODUCTION: Hepatitis C virus (HCV) treatment can significantly reduce the risk of liver-related mortality; however, many patients remain unaware of their infection in clinical practice. The aim of this study is to compare the effectiveness of inreach, with and without mailed outreach, to increase HCV screening and follow-up in a large, difficult-to-reach patient population. METHODS: We conducted a pragmatic randomized clinical trial from August 2018 to May 2019 in a large safety-net health system. Patients born between 1945 and 1965 were randomly assigned (1:1) to inreach with an electronic health record reminder to providers (n = 6,195) or inreach plus mailed HCV screening outreach (n = 6,191) to complete HCV antibody screening. Outreach also included processes to promote HCV RNA testing among those with a positive HCV antibody and linkage to care among those with positive HCV RNA. The primary outcome was completion of HCV antibody testing within 3 months of randomization (ClinicalTrials.gov NCT03706742). RESULTS: We included 12,386 eligible patients (median age 60 years; 46.5% Hispanic, 33.0% Black, and 16.0% White). In intent-to-treat analyses, HCV screening completion was significantly higher among inreach-plus-outreach patients than inreach-alone patients at 3 months (14.6% vs 7.4%, P < 0.001) and 6 months (17.4% vs 9.8%, P < 0.001) after randomization. Among those who completed HCV screening within 6 months, a higher proportion of inreach-plus-outreach patients with positive antibody results completed RNA testing within 3 months than inreach-alone patients (81.1% vs 57.1%, respectively, P = 0.02); however, linkage to care within 3 months of HCV infection confirmation did not significantly differ between the 2 groups (48.1% vs 75.0%, respectively, P = 0.24). DISCUSSION: Among difficult-to-reach patients, a combination of inreach and mailed outreach significantly increased HCV screening compared with inreach alone. However, HCV screening completion in both arms remained low, highlighting a need for more intensive interventions.
Fitness effects of mutation in natural populations of Arabidopsis thaliana reveal a complex influence of local adaptation

Little is empirically known about the contribution of mutations to fitness in natural environments. However, Fisher's Geometric Model (FGM) provides a conceptual foundation to consider the influence of the environment on mutational effects. To quantify mutational properties in the field, we established eight sets of MA lines (7‐10 generations) derived from eight founders collected from natural populations of Arabidopsis thaliana from French and Swedish sites, representing the range margins of the species in Europe. We reciprocally planted the MA lines and their founders at French and Swedish sites, allowing us to test predictions of FGM under naturally occurring environmental conditions. The performance of the MA lines relative to each other and to their respective founders confirmed some and contradicted other predictions of the FGM: the contribution of mutation to fitness variance increased when the genotype was in an environment where its fitness was low, that is, in the away environment, but mutations were more likely to be beneficial when the genotype was in its home environment. Consequently, environmental context plays a large role in the contribution of mutations to the evolutionary process and local adaptation does not guarantee that a genotype is at or close to its optimum.
Completeness of Intervention Reporting of Clinical Trials Published in Highly Ranked Obesity Journals

Randomized controlled trials (RCTs) play a crucial role in the research and advancement of medical treatment. A cross‐sectional study design was utilized to analyze the completeness of intervention reporting using the Template for Intervention Description and Replication (TIDieR) checklist and to evaluate factors associated with intervention reporting. A comparison of the completeness of intervention reporting before and after the publication of TIDieR was sought.
Early childhood caries in multilingual community.

OBJECTIVE The aim of the study was to determine the prevalence and severity of early childhood caries (ECC) among different social groups of preschool children in ethnic and multilingual diverse community such as South Backa District (SBD), Republic of Serbia. METHODS This survey was a cross-sectional analytical study and sample type has been projected by simple random choice of 13-71 months old children together with their parents of varied socioeconomic status (SES) and nationality in SBD. Preschool children were randomly selected through a two-stage cluster sampling procedure and parents were invited to answer the questionnaire regarding SES, native language, education, and income issues. The WHO caries diagnostic criterion was used and the severity of ECC was defined by Wine's modified criteria. The data was further analyzed using the SPSS for Windows Microsoft Excel, version 21. The percentage of caries-free children was compared using the χ2 test, and one-way ANOVA was used to compare the mean disease indices at the 5% significance. RESULTS A total of 341 children were examined and the prevalence of ECC was 30.5%. "White spot" initial caries lesions were the most prevalent form and the highest disease frequency was found in male children (p = 0.038), who did not speak official Serbian language (p = 0.009), in children of the part-time employed parents (p < 0.001), with elementary education (p = 0.001), in low monthly income families (p = 0.023), and Roma ethnic group. CONCLUSIONS The complex interaction of risk factors like social environment along with ethnicity and Serbian language ignorance had a significant influence on the prevalence and severity of ECC in preschool children of this multi-ethnic region.
Nonlinear Vibration Study Based on Uncertainty Analysis in MEMS Resonant Accelerometer

This paper aims to develop a resonant accelerometer for high-sensitivity detection and to investigate the nonlinear vibration of the MEMS resonant accelerometer driven by electrostatic comb fingers. First, a nonlinear vibration model of the resonator with comb fingers in a MEMS resonant accelerometer is established. Then, the nonlinear and nonlinear stiffness coefficients are calculated and analyzed with the Galérkin principle. The linear natural frequency, tracking error, and nonlinear frequency offset are obtained by multi-scale method. Finally, to further analyze the nonlinear vibration, a sample-based stochastic model is established, and the uncertainty analysis method is applied. It is concluded from the results that nonlinear vibration can be reduced by reducing the resonant beam length and increasing the resonant beam width and thickness. In addition, the resonant beam length and thickness have more significant effects, while the resonant beam width and the single concentrated mass of comb fingers have little effect, which are verified by experiments. The results of this research have proved that uncertainty analysis is an effective approach in nonlinear vibration analysis and instructional in practical resonant accelerometer design.
History of premorbid depression is a risk factor for COVID-related mortality: Analysis of a retrospective cohort of 1,387 COVID+ patients

Background: The goal of the present work was to examine risk factors for mortality in a 1,387 COVID+ patients admitted to a hospital in Suffolk County, NY. Methods: Data were collated by the hospital epidemiological service for patients admitted from 3/7/2020-9/1/2020. Time until final discharge or death was the outcome. Cox proportional hazards models were used to estimate time until death among admitted patients. Findings: In total, 99.06% of cases had resolved leading to 1,179 discharges and 211 deaths. Length of stay was significantly longer in those who died as compared to those who did not p=0.007). Of patients who had been discharged (n=1,179), 54 were readmitted and 9 subsequently died. Multivariable-adjusted Cox proportional hazards regression revealed that in addition to older age, male sex, and heart failure, a history of premorbid depression was a risk factor for COVI-19 mortality. Interpretation: While an increasing number of studies have shown effects linking cardiovascular risk factors with increased risk of mortality in COVID+ patients, this study reports that history of depression is a risk factor for COVID mortality.
