Using electronic health record data to link families: an illustrative example using intergenerational patterns of obesity. J Am Med Inform Assoc 2023; 30:915-922. [PMID: 36857086 PMCID: PMC10114127 DOI: 10.1093/jamia/ocad028] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/14/2022] [Revised: 02/03/2023] [Accepted: 02/16/2023] [Indexed: 03/02/2023] Open
Abstract
OBJECTIVE Electronic health record (EHR) data are a valuable resource for population health research but lack critical information such as relationships between individuals. Emergency contacts in EHRs can be used to link family members, creating a population that is more representative of a community than traditional family cohorts. MATERIALS AND METHODS We revised a published algorithm: relationship inference from the electronic health record (RIFTEHR). Our version, Pythonic RIFTEHR (P-RIFTEHR), identifies a patient's emergency contacts, matches them to existing patients (when available) using network graphs, checks for conflicts, and infers new relationships. P-RIFTEHR was run on December 15, 2021 in the Northwestern Medicine Electronic Data Warehouse (NMEDW) on approximately 2.95 million individuals and was validated using the existing link between children born at NM hospitals and their mothers. As proof-of-concept, we modeled the association between parent and child obesity using logistic regression. RESULTS The P-RIFTEHR algorithm matched 1 157 454 individuals in 448 278 families. The median family size was 2, the largest was 32 persons, and 247 families spanned 4 generations or more. Validation of the mother-child pairs resulted in 95.1% sensitivity. Children were 2 times more likely to be obese if a parent is obese (OR: 2.30; 95% CI, 2.23-2.37). CONCLUSION P-RIFTEHR can identify familiar relationships in a large, diverse population in an integrated health system. Estimates of parent-child inheritability of obesity using family structures identified by the algorithm were consistent with previously published estimates from traditional cohort studies.

Abstract
Rosmarinic acid (RA) is a natural phenolic compound present in culinary herbs of the Boraginaceae, Lamiaceae/Labiatae, and Nepetoideae families. While the medicinal applications of these plants have been known for ages, RA has only been relatively recently established as an effective ameliorative agent against various disorders including cardiac diseases, cancer, and neuropathologies. In particular, several studies have confirmed the neuroprotective potential of RA in multiple cellular and animal models, as well as in clinical studies. The neuroprotective effects mediated by RA stem from its multimodal actions on a plethora of cellular and molecular pathways; including oxidative, bioenergetic, neuroinflammatory, and synaptic signaling. In recent years, RA has garnered tremendous interest as an ideal therapeutic candidate for treating neurodegenerative diseases. This review first briefly discusses the pharmacokinetics of RA and then proceeds to detail the neuroprotective mechanisms of RA at the molecular levels. Finally, the authors focus on the ameliorative potential of RA against several central nervous system (CNS) disorders, ranging from neuropsychological stress and epilepsy to neurodegenerative diseases such as Alzheimer's disease, Huntington's disease, Parkinson's disease, Lewy body dementia, and amyotrophic lateral sclerosis.

Abstract
PURPOSE The study aims to describe the quality of life (QoL) in Omani children with epilepsy at Sultan Qaboos University Hospital, Oman. METHODS One hundred and one Omani children, with an age range from 5 to 18 years, diagnosed with epilepsy were enrolled in the study over 3 months. Descriptive epidemiology was used to characterize QoL in these children. QoL was measured using the PedsQL (4.0) questionnaire, a 23-item child and parent report questionnaire. Analysis of variance (ANOVA) was used to compare mean QoL scores, and agreement between the QoL reports of children and parents was evaluated using Spearman's rho; while, Multivariate analysis of variance (MANOVA) was performed to determine differences in subscale ratings. RESULTS Factors affecting QoL included family status, income level, social security coverage, type of treatment, seizure frequency, age of onset, and seizure-free duration in years. Children between 5 and 7 years and females, in general, were most affected, as reflected by the overall QoL subscale. Consistency between the children's self-reports and parent proxy reports on the PedsQL™ was moderate to low. CONCLUSION Omani children with epilepsy have poor QoL, and their psychosocial function is severely affected. Therefore, QoL should be an important outcome measure in managing children with epilepsy rather than just seizure control.

Abstract
Despite the emergence of novel targeted treatments for atopic dermatitis (AD), there is a lack of guidelines on standardizing analysis of clinical trial data. To define and estimate meaningful treatment comparisons, several factors, including intercurrent events, must be taken into account. Intercurrent events are defined as events occurring after treatment initiation that affect either the interpretation or existence of the measurements associated with clinical questions of interest. Due to the relapsing, unpredictable nature of AD, intercurrent events frequently occur in AD trials, such as use of rescue therapy for intense itch and sleep deprivation. Despite the impact of intercurrent events in AD, they are often handled in an inconsistent manner across trials, which limits results interpretation. The estimand framework is increasingly used to estimate treatment effects while accounting for intercurrent events. This review explores how guidance from the International Council for Harmonization of Technical Requirements for Pharmaceuticals for Human Use (ICH) on the use of estimands can be applied to support AD clinical trial design and analysis. We propose that estimands are used in AD trials and defined early during trial design. The use of estimands can provide clinicians with interventional trial results that are more reflective of clinical practice, help facilitate comparisons across clinical trials, and are more informative to enable improved treatment selection for patients.

Abstract
Mitochondria regulate multiple aspects of neuronal development, physiology, plasticity, and pathology through their regulatory roles in bioenergetic, calcium, redox, and cell survival/death signalling. While several reviews have addressed these different aspects, a comprehensive discussion focussing on the relevance of isolated brain mitochondria and their utilities in neuroscience research has been lacking. This is relevant because the employment of isolated mitochondria rather than their in situ functional evaluation, offers definitive evidence of organelle-specificity, negating the interference from extra mitochondrial cellular factors/signals. This mini-review was designed primarily to explore the commonly employed in organello analytical assays for the assessment of mitochondrial physiology and its dysfunction, with a particular focus on neuroscience research. The authors briefly discuss the methodologies for biochemical isolation of mitochondria, their quality assessment, and cryopreservation. Further, the review attempts to accumulate the key biochemical protocols for in organello assessment of a multitude of mitochondrial functions critical for neurophysiology, including assays for bioenergetic activity, calcium and redox homeostasis, and mitochondrial protein translation. The purpose of this review is not to examine each and every method or study related to the functional assessment of isolated brain mitochondria, but rather to assemble the commonly used protocols of in organello mitochondrial research in a single publication. The hope is that this review will provide a suitable platform aiding neuroscientists to choose and apply the required protocols and tools to address their particular mechanistic, diagnostic, or therapeutic question dealing within the confines of the research area of mitochondrial patho-physiology in the neuronal perspective.

Abstract
Purple sweet potato is commonly cooked by boiling, steaming, baking and microwaving.
However, information on the effects of cooking methods on the physicochemical
properties, antioxidants properties and sensory acceptability is limited. In this study, the
effect of cooking methods (boiling, steaming, baking and microwaving) on the
physicochemical properties, antioxidant properties and sensory acceptability of purple
sweet potato were investigated. The results showed that the boiled sample was the softest
(hardness of 933.39 g) and also had the highest total colour difference (18.56), while the
steamed sample was the most adhesive (-92.35 g.s) and least cohesive (0.41). An
increased moisture content caused a decrease in other proximate compositions in the
samples. The baked sample had the highest antioxidant properties, with 232.20 mg
GAE/100 g of total phenolic content, 2.05 mg cyaniding-3-glucoside/L of total
anthocyanins, 61.95% of DPPH and 79.20% of ABTS radical-scavenging activity. The
steamed sample was rated most acceptable by the panellists.

Abstract
Additive manufacturing (AM) highlights developing complex and efficient parts for various uses. Fused deposition modelling (FDM) is the most frequent fabrication procedure used to make polymer products. Although it is widely used, due to its low characteristics, such as weak mechanical properties and poor surface, the types of polymer material that may be produced are limited, affecting the structural applications of FDM. Therefore, the FDM process utilises the polymer composition to produce a better physical product. The review's objective is to systematically document all critical information on FDMed-polymer composite processing, specifically for part fabrication. The review covers the published works on the FDMed-polymer composite from 2011 to 2021 based on our systematic literature review of more than 150 high-impact related research articles. The base and filler material used, and the process parameters including layer height, nozzle temperature, bed temperature, and screw type are also discussed in this review. FDM is utilised in various biomedical, automotive, and other manufacturing industries. This study is expected to be one of the essential pit-stops for future related works in the FDMed-polymeric composite study.

Abstract
OBJECTIVE The ensuing ischemia due to the disruption of blood supply to the brain is one of the most common causes of stroke. Evidence suggests a clear association of the ischemic injury with vascular dementia and Alzheimer's disease (AD). In response to the brain ischemia, a cascade reaction starts leading to neuronal damage due to oxidative stress and other inflammatory mediators. A pilot study was done, which showed that following stroke, monomeric-C-reactive protein (mCRP) is expressed in large quantities around the infarcted zone and this CRP is able to induce neurodegeneration and inflammation potentially perpetuating dementia. MATERIALS AND METHODS We examined both patient brain samples and excised mouse brain tissue, previously injected with 1.75 mg/mL mCRP into the CA1 area of the hippocampus through the stereotactic surgical procedures and followed them over a period of over 6 months. The distribution of mCRP was examined through immunohistochemistry (mouse anti-human mCRP-specific antibodies 8C10). RESULTS We observed a novel finding: those micro vessels close to the injection location were strongly stained with mCRP only in the mice that had been injected with mCRP, indicating that this small blood vessel can spread it throughout the brain. CONCLUSIONS mCRP found in the brain after a hemorrhagic stroke promotes damage over a large area via the induction of inflammation and degeneration of perivascular compartments.

Abstract
Simple Summary Brain metastases are amongst the most invasive and lethal cancers. Yet, effective methods for their diagnosis and therapy have remained elusive. While several factors are responsible for this, the primary hurdle has been the absence of an appropriate delivery strategy for the diagnostic/therapeutic agents to the brain. Fortunately, the advent of nanobiotechnology and the advances in bioengineering techniques have provided some hope to circumvent this hurdle. The aim of this review is to evaluate the suitability of novel smart nanobiotechnological approaches in brain cancer therapy. We discuss several state-of-the-art strategies for specific delivery of drugs to brain cancer sites with minimal side effects. We further delineate several classes of nanoplatforms that have generated tremendous interest among contemporary scientists as potential agents for brain cancer therapy. In doing so, the authors hope that the review will serve as a platform for further studies for the discovery of brain cancer strategies. Abstract Despite their low prevalence, brain tumors are among the most lethal cancers. They are extremely difficult to diagnose, monitor and treat. Conventional anti-cancer strategies such as radio- and chemotherapy have largely failed, and to date, the development of even a single effective therapeutic strategy against central nervous system (CNS) tumors has remained elusive. There are several factors responsible for this. Brain cancers are a heterogeneous group of diseases with variable origins, biochemical properties and degrees of invasiveness. High-grade gliomas are amongst the most metastatic and invasive cancers, which is another reason for therapeutic failure in their case. Moreover, crossing the blood brain and the blood brain tumor barriers has been a significant hindrance in the development of efficient CNS therapeutics. Cancer nanomedicine, which encompasses the application of nanotechnology for diagnosis, monitoring and therapy of cancers, is a rapidly evolving field of translational medicine. Nanoformulations, because of their extreme versatility and manipulative potential, are emerging candidates for tumor targeting, penetration and treatment in the brain. Moreover, suitable nanocarriers can be commissioned for theranostics, a combinatorial personalized approach for simultaneous imaging and therapy. This review first details the recent advances in novel bioengineering techniques that provide promising avenues for circumventing the hurdles of delivering the diagnostic/therapeutic agent to the CNS. The authors then describe in detail the tremendous potential of utilizing nanotechnology, particularly nano-theranostics for brain cancer imaging and therapy, and outline the different categories of recently developed next-generation smart nanoformulations that have exceptional potential for making a breakthrough in clinical neuro-oncology therapeutics.

Abstract
Growth assessment is an essential component of child health surveillance. The most influential tool in the growth assessment is the growth chart. Growth parameters of children are usually interpreted in relation to international standards like the NCHS/1977, CDC/2000 and WHO/2007 growth charts. This comparative study was carried out in the Department of Paediatrics, Mymensingh Medical College, Mymensingh, Bangladesh from November 2014 to October 2015 to compare the growth parameters of children using 2000 CDC standards and 2007 WHO standards. A total of five hundred healthy school children, aged 6 to 10 years were randomly selected proportionately from each class of five government primary schools from Mymensingh city area. Children with physical deformities and acutely ill and those with chronic debilitating diseases were excluded from the study. The mean and median weight, height and BMI were calculated for each age and sex. The median weight, height and BMI were then standardized by converting them to Z-scores (SD) for comparing against known reference values of 2000 CDC and 2007 WHO charts. Among 500 children, 252(50.4%) were boys and 248(49.6%) were girls. The mean age was found 8.0±1.42 years in boys and 8.04±1.42 years in girls. The mean weight was found 24.4±6.36kg in boys and 24.08±6.35kg in girls. The mean height was 125.90±10.16cm in boys and 125.38±10.74cm in girls. The mean weight, height and BMI of boys and girls were found to be lower in all age groups with compared to 2000 CDC standard and 2007 WHO standard but were closer to the WHO standards compared to the CDC standards. According to CDC and WHO in the study it was observed that underweight was found 16.3% and 14.7%, stunting 7.1% and 6.7%, overweight 6.7% and 8.7%, and obese 2.8% and 4.0% respectively in male subjects. On the other hand, in female subjects it was observed that according to CDC chart and WHO chart underweight was found 19.4% and 13.3%, stunting 6.0% and 4.8%, overweight 7.3% and 8.1% and obese 2.0% and 2.0% respectively. The findings in this study imply that growth pattern of Bangladeshi school children is closer with WHO standards and wider from CDC standards.

Abstract
Tissue biopsy analysis has conventionally been the gold standard for cancer prognosis, diagnosis and prediction of responses/resistances to treatments. The existing biopsy procedures used in clinical practice are, however, invasive, painful and often associated with pitfalls like poor recovery of tumor cells and infeasibility for repetition in single patients. To circumvent these limitations, alternative non-invasive, rapid and economical, yet sturdy, consistent and dependable, biopsy techniques are required. Liquid biopsy is an emerging technology that fulfills these criteria and potentially much more in terms of subject-specific real-time monitoring of cancer progression, determination of tumor heterogeneity and treatment responses, and specific identification of the type and stages of cancers. The present review first briefly revisits the state-of-the-art technique of liquid biopsy and then proceeds to address in detail, the advances in the potential clinical applications of four major biological agencies present in liquid biopsy samples (circulating tumor DNA (ctDNA), circulating tumor cells (CTCs), exosomes and tumor-educated platelets (TEPs)). Finally, the authors conclude with the limitations that need to be addressed in order for liquid biopsy to effectively replace the conventional invasive biopsy methods in the clinical settings.

Abstract
BACKGROUND Patients with prurigo nodularis (PN) have multiple itchy nodules, impaired quality of life and sleep deprivation. Prurigo nodularis patients have a high burden of disease, primarily due to the intensity of the itch. It is reasonable to expect that rapid relief of itch - and associated improvement of sleep - are highly valued clinical outcomes for patients. Nemolizumab is an IL-31A-receptor inhibitor that modulates the neuroimmune response with reported positive efficacy and safety data in a phase 2 study of PN. OBJECTIVES To evaluate the onset of action of nemolizumab on itch and sleep disturbances. METHODS Post hoc analysis of a phase 2 trial of nemolizumab 0.5 mg/kg SC vs. placebo in patients (n = 70) with moderate-to-severe PN (≥20 nodules) and severe pruritus (NRS ≥ 7). Time to significant reduction was assessed for peak pruritus (PP) and sleep disturbance (SD) using numerical rating scales (NRS), also assessed was scratching time during sleep. RESULTS Nemolizumab significantly reduced itch vs. placebo within 48 h (PP NRS -19.5% vs. -5.8%, respectively, P = 0.014). Significant difference between nemolizumab and placebo in reducing itch by ≥4 on PP NRS was achieved at Day 3 (23.5% vs. 0%, P < 0.001). A significant difference in SD NRS was reported by Day 4 (-24.0% vs. -4.3% placebo, P = 0.012). In addition, there was a separation between groups in SD responders (decrease of ≥4 points) in favour of nemolizumab by Day 2 (8.8% vs. 0%, P = 0.037). Sleep continued improving through Week 4, when there was a -56.0% reduction in SD NRS vs. -22.9% placebo (P < 0.001). Actigraphy data showed improvement in scratch/sleep duration for nemolizumab vs. placebo, respectively, by Week 1 (-32.15 vs. +28.15 min/h, P = 0.001). CONCLUSION Nemolizumab has a rapid and robust onset of action in PN with itch reduction and improvement of sleep within 48 h.

Abstract
Fish sauce is a well-known condiment for its delicious flavour developed through a
fermentation process. It is generally used as an additive for flavour enhancement in
cooking. The fish sauce comes in several appearances, ranging from a clear liquid with
light colour and texture to a dark and cloudy liquid. This product is produced by a longduration of fermentation process by the combination of fish and salt. This high salt
fermentation began with the action of enzymes from fish muscle and its digestive tracts,
then continued with halophilic bacteria activity to further break down fish proteins in
producing a liquid product with a mixture of soluble proteins, peptides and amino acids.
This review is comprised of two sections, the first section covers various processing
methods of fish sauces, mainly in the Asia region, namely Nam-pla, Nuoc-mam, Yu-lu,
Ishiru, Shottsuru, Bakasang and Budu. These fish sauces roughly involve applying salt for
fermentation, with different fish species, salt concentration, fermentation duration and
processing techniques. The later section covers taste-contributing components of fish
sauces in the scope of amino acids and peptides. Five of the major amino acids found to
taste in the fish sauce, glutamic acid, threonine, alanine, methionine and histidine, are also
reviewed in this paper. Sensory peptides in fish sauces shown in this paper are peptides
with salt taste enhancement properties and peptides exhibiting sweet, sour, bitter, umami
and kokumi tastes.

Scoping Review of Existing Evaluations of Smokeless Tobacco Control Policies: What Is Known About Countries Covered, Level of Jurisdictions, Target Groups Studied, and Instruments Evaluated? Nicotine Tob Res 2022; 24:1344-1354. [PMID: 35428887 DOI: 10.1093/ntr/ntac102] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/12/2020] [Revised: 03/17/2022] [Accepted: 04/12/2022] [Indexed: 11/13/2022]
Abstract
OBJECTIVE The implementation of smokeless tobacco control policies lags behind those for smoking. This scoping review summarizes the studies that evaluated public policies on smokeless tobacco regulation (SLT) and provides an overview of the jurisdictional level, target groups, and policy instruments. METHODS Seven databases were systematically searched for studies reporting on public policies regulating SLT. Two reviewers independently screened all studies. Data extraction was performed using a predefined extraction form. Extraction was replicated for 10% of the identified studies for quality assurance. A narrative synthesis of the included studies was used to analyze and interpret the data. The protocol was published beforehand with the Open Science Foundation (OSF). RESULTS Fourty articles comprising 41 studies were included. Most of the studies reported in the articles were conducted in the United States (n = 17) or India (n = 14). Most studies reported outcomes for students (n = 8), retailers/sellers (n = 8), and users/former users (n = 5). The impact of public policies on smokeless tobacco use, in general, was most frequently assessed (n = 9), followed by the impact of taxes (n = 7), product bans (n = 6), sales/advertising bans near educational institutions (n = 4), and health warnings (n = 3) on consumer behavior. CONCLUSIONS There are significant gaps in the evaluation of smokeless tobacco regulation studies that need to be filled by further research to understand the observed outcomes. WHO reporting on Framework Convention on Tobacco Control (FCTC) implementation should be linked to studies evaluating smokeless tobacco control measures at all levels of jurisdictions and in countries not members of the WHO FCTC or do not provide data. IMPLICATION Large gaps in the evaluation of SLT control policies exist. For some countries, WHO FCTC evaluations are available for different levels of jurisdictions. In countries with a strong federal structure, there is a lack of data beyond the national level to provide a more detailed look at compliance, indirect effects, or implementation gaps. More research is needed at all levels of jurisdictions, which add to the work of the WHO to understand what works for which target group, how the different levels of jurisdiction interact, how the real-world context can be incorporated, and what indirect effects may occur.

anchovy: a review. FOOD RESEARCH 2022. [DOI: 10.26656/fr.2017.6(4).419] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Indexed: 11/12/2022] Open
Abstract
Anchovies are the small pelagic fish that belongs to the family of Engraulidae dominant
all over the Indo-Pacific region, which account for human consumption and as feed for
other larger fish. Anchovies are rich in macronutrients and micronutrients such as protein,
carbohydrate, fat and amino acids. In addition, anchovy is composed of well-balanced
amino acid compositions containing eight essential amino acids and eight non-essential
amino acids. The nutritive value of anchovies has become the reason for numerous food
applications. Proximate analysis is vital in the food industry for the development and
quality controls of food products. Knowledge and information regarding the proximate
composition of fish are essential in the food processing technology of fish products at
commercial and industrial scales. Additionally, this review highlights both conventional
and innovative anchovy-based food items. The review demonstrated that anchovies have
several possible breakthroughs in the food industry, as shown by their proximate
composition and the amino acid profiles used in various food items.

[PMID: 35750772 PMCID: PMC9232500 DOI: 10.1038/s41598-022-14428-y] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/20/2022] [Accepted: 06/07/2022] [Indexed: 11/09/2022] Open
Abstract
The present study aims to investigate the performance of microchannel heat sink via numerical simulations, based on the first and second law of thermodynamics. The heat transfer and flow characteristics of rectangular microchannel heat sinks have been improved by adding six different types of surface enhancers. The cross-sections include rectangular, triangular, and hexagonal-shaped ribs and cones. The cones have been created from the same cross-sections of ribs by drafting them at an angle of 45° orthogonal to the base, which is expected to decrease the pressure drop, dramatically. The performance of ribs and cones has been evaluated using different parameters such as friction factor, wall shear stress, entropy generation rate, augmentation entropy generation number, thermal resistance, and transport efficiency of thermal energy. The results of the present study revealed that the novel effect of coning at an angle of 45° reduces frictional losses (Maximum pressure drop reduced is 85%), however; a compromise on thermal behavior has been shown (Maximum Nusselt number reduced is 25%). Similarly, the application of coning has caused a significant reduction in wall shear stress and friction factor which can lead to reducing the pumping power requirements. Moreover, triangular ribs have more ability to transfer thermal energy than rectangular and hexagonal ribs. Furthermore, it has been examined in the present study that the trend of total entropy generation rate for triangular ribs decreases up to Re = 400 and then increases onwards which means that thermal losses are more significant than frictional losses at lower Reynolds number. However, frictional losses dominate over thermal losses at higher Reynolds numbers, where vortex generation takes place, especially in triangular ribs.

[PMID: 35813825 PMCID: PMC9263924 DOI: 10.3389/fmolb.2022.906387] [Citation(s) in RCA: 4] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/28/2022] [Accepted: 05/30/2022] [Indexed: 11/13/2022] Open
Abstract
Mycobacterium tuberculosis (M. tb) gene Rv1515c encodes a conserved hypothetical protein exclusively present within organisms of MTB complex and absent in non-pathogenic mycobacteria. In silico analysis revealed that Rv1515c contain S-adenosylmethionine binding site and methyltransferase domain. The DNA binding and DNA methyltransferase activity of Rv1515c was confirmed in vitro. Knock-in of Rv1515c in a model mycobacteria M. smegmatis (M. s_Rv1515c) resulted in remarkable physiological and morphological changes and conferred the recombinant strain with an ability to adapt to various stress conditions, including resistance to TB drugs. M. s_Rv1515c was phagocytosed at a greater rate and displayed extended intra-macrophage survival in vitro. Recombinant M. s_Rv1515c contributed to enhanced virulence by suppressing the host defense mechanisms including RNS and ROS production, and apoptotic clearance. M. s_Rv1515c, while suppressing the phagolysosomal maturation, modulated pro-inflammatory cytokine production and also inhibited antigen presentation by downregulating the expression of MHC-I/MHC-II and co-stimulatory signals CD80 and CD86. Mice infected with M. s_Rv1515c produced more Treg cells than vector control (M. s_Vc) and exhibited reduced effector T cell responses, along-with reduced expression of macrophage activation markers in the chronic phase of infection. M. s_Rv1515c was able to survive in the major organs of mice up to 7 weeks post-infection. These results indicate a crucial role of Rv1515c in M. tb pathogenesis.

[PMID: 35682712 PMCID: PMC9181759 DOI: 10.3390/ijms23116039] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/28/2022] [Revised: 05/21/2022] [Accepted: 05/25/2022] [Indexed: 02/04/2023] Open
Abstract
Altered arginine metabolism (including the polyamine system) has recently been implicated in the pathogenesis of tauopathies, characterised by hyperphosphorylated and aggregated microtubule-associated protein tau (MAPT) accumulation in the brain. The present study, for the first time, systematically determined the time-course of arginine metabolism changes in the MAPT P301S (PS19) mouse brain at 2, 4, 6, 8 and 12 months of age. The polyamines putrescine, spermidine and spermine are critically involved in microtubule assembly and stabilization. This study, therefore, further investigated how polyamine biosynthetic and catabolic enzymes changed in PS19 mice. There were general age-dependent increases of L-arginine, L-ornithine, putrescine and spermidine in the PS19 brain (particularly in the hippocampus and parahippocampal region). While this profile change clearly indicates a shift of arginine metabolism to favor polyamine production (a polyamine stress response), spermine levels were decreased or unchanged due to the upregulation of polyamine retro-conversion pathways. Our results further implicate altered arginine metabolism (particularly the polyamine system) in the pathogenesis of tauopathies. Given the role of the polyamines in microtubule assembly and stabilization, future research is required to understand the functional significance of the polyamine stress response and explore the preventive and/or therapeutic opportunities for tauopathies by targeting the polyamine system.

Abstract
BACKGROUND Our March 2021 edition of this review showed thoracic imaging computed tomography (CT) to be sensitive and moderately specific in diagnosing COVID-19 pneumonia. This new edition is an update of the review. OBJECTIVES Our objectives were to evaluate the diagnostic accuracy of thoracic imaging in people with suspected COVID-19; assess the rate of positive imaging in people who had an initial reverse transcriptase polymerase chain reaction (RT-PCR) negative result and a positive RT-PCR result on follow-up; and evaluate the accuracy of thoracic imaging for screening COVID-19 in asymptomatic individuals. The secondary objective was to assess threshold effects of index test positivity on accuracy. SEARCH METHODS We searched the COVID-19 Living Evidence Database from the University of Bern, the Cochrane COVID-19 Study Register, The Stephen B. Thacker CDC Library, and repositories of COVID-19 publications through to 17 February 2021. We did not apply any language restrictions. SELECTION CRITERIA We included diagnostic accuracy studies of all designs, except for case-control, that recruited participants of any age group suspected to have COVID-19. Studies had to assess chest CT, chest X-ray, or ultrasound of the lungs for the diagnosis of COVID-19, use a reference standard that included RT-PCR, and report estimates of test accuracy or provide data from which we could compute estimates. We excluded studies that used imaging as part of the reference standard and studies that excluded participants with normal index test results. DATA COLLECTION AND ANALYSIS The review authors independently and in duplicate screened articles, extracted data and assessed risk of bias and applicability concerns using QUADAS-2. We presented sensitivity and specificity per study on paired forest plots, and summarized pooled estimates in tables. We used a bivariate meta-analysis model where appropriate. MAIN RESULTS We included 98 studies in this review. Of these, 94 were included for evaluating the diagnostic accuracy of thoracic imaging in the evaluation of people with suspected COVID-19. Eight studies were included for assessing the rate of positive imaging in individuals with initial RT-PCR negative results and positive RT-PCR results on follow-up, and 10 studies were included for evaluating the accuracy of thoracic imaging for imagining asymptomatic individuals. For all 98 included studies, risk of bias was high or unclear in 52 (53%) studies with respect to participant selection, in 64 (65%) studies with respect to reference standard, in 46 (47%) studies with respect to index test, and in 48 (49%) studies with respect to flow and timing. Concerns about the applicability of the evidence to: participants were high or unclear in eight (8%) studies; index test were high or unclear in seven (7%) studies; and reference standard were high or unclear in seven (7%) studies. Imaging in people with suspected COVID-19 We included 94 studies. Eighty-seven studies evaluated one imaging modality, and seven studies evaluated two imaging modalities. All studies used RT-PCR alone or in combination with other criteria (for example, clinical signs and symptoms, positive contacts) as the reference standard for the diagnosis of COVID-19. For chest CT (69 studies, 28285 participants, 14,342 (51%) cases), sensitivities ranged from 45% to 100%, and specificities from 10% to 99%. The pooled sensitivity of chest CT was 86.9% (95% confidence interval (CI) 83.6 to 89.6), and pooled specificity was 78.3% (95% CI 73.7 to 82.3). Definition for index test positivity was a source of heterogeneity for sensitivity, but not specificity. Reference standard was not a source of heterogeneity. For chest X-ray (17 studies, 8529 participants, 5303 (62%) cases), the sensitivity ranged from 44% to 94% and specificity from 24 to 93%. The pooled sensitivity of chest X-ray was 73.1% (95% CI 64. to -80.5), and pooled specificity was 73.3% (95% CI 61.9 to 82.2). Definition for index test positivity was not found to be a source of heterogeneity. Definition for index test positivity and reference standard were not found to be sources of heterogeneity. For ultrasound of the lungs (15 studies, 2410 participants, 1158 (48%) cases), the sensitivity ranged from 73% to 94% and the specificity ranged from 21% to 98%. The pooled sensitivity of ultrasound was 88.9% (95% CI 84.9 to 92.0), and the pooled specificity was 72.2% (95% CI 58.8 to 82.5). Definition for index test positivity and reference standard were not found to be sources of heterogeneity. Indirect comparisons of modalities evaluated across all 94 studies indicated that chest CT and ultrasound gave higher sensitivity estimates than X-ray (P = 0.0003 and P = 0.001, respectively). Chest CT and ultrasound gave similar sensitivities (P=0.42). All modalities had similar specificities (CT versus X-ray P = 0.36; CT versus ultrasound P = 0.32; X-ray versus ultrasound P = 0.89). Imaging in PCR-negative people who subsequently became positive For rate of positive imaging in individuals with initial RT-PCR negative results, we included 8 studies (7 CT, 1 ultrasound) with a total of 198 participants suspected of having COVID-19, all of whom had a final diagnosis of COVID-19. Most studies (7/8) evaluated CT. Of 177 participants with initially negative RT-PCR who had positive RT-PCR results on follow-up testing, 75.8% (95% CI 45.3 to 92.2) had positive CT findings. Imaging in asymptomatic PCR-positive people For imaging asymptomatic individuals, we included 10 studies (7 CT, 1 X-ray, 2 ultrasound) with a total of 3548 asymptomatic participants, of whom 364 (10%) had a final diagnosis of COVID-19. For chest CT (7 studies, 3134 participants, 315 (10%) cases), the pooled sensitivity was 55.7% (95% CI 35.4 to 74.3) and the pooled specificity was 91.1% (95% CI 82.6 to 95.7). AUTHORS' CONCLUSIONS Chest CT and ultrasound of the lungs are sensitive and moderately specific in diagnosing COVID-19. Chest X-ray is moderately sensitive and moderately specific in diagnosing COVID-19. Thus, chest CT and ultrasound may have more utility for ruling out COVID-19 than for differentiating SARS-CoV-2 infection from other causes of respiratory illness. The uncertainty resulting from high or unclear risk of bias and the heterogeneity of included studies limit our ability to confidently draw conclusions based on our results.

Abstract
Mycobacterium tuberculosis (Mtb) is the causative agent of human tuberculosis (TB) which primarily infects the macrophages. Nearly a quarter of the world's population is infected latently by Mtb. Only around 5%-10% of those infected develop active TB disease, particularly during suppressed host immune conditions or comorbidity such as HIV, hinting toward the heterogeneity of Mtb infection. The aerosolized Mtb first reaches the lungs, and the resident alveolar macrophages (AMs) are among the first cells to encounter the Mtb infection. Evidence suggests that early clearance of Mtb infection is associated with robust innate immune responses in resident macrophages. In addition to lung-resident macrophage subsets, the recruited monocytes and monocyte-derived macrophages (MDMs) have been suggested to have a protective role during Mtb infection. Mtb, by virtue of its unique cell surface lipids and secreted protein effectors, can evade killing by the innate immune cells and preferentially establish a niche within the AMs. Continuous efforts to delineate the determinants of host defense mechanisms have brought to the center stage the crucial role of macrophage phenotypical variations for functional adaptations in TB. The morphological and functional heterogeneity and plasticity of the macrophages aid in confining the dissemination of Mtb. However, during a suppressed or hyperactivated immune state, the Mtb virulence factors can affect macrophage homeostasis which may skew to favor pathogen growth, causing active TB. This mini-review is aimed at summarizing the interplay of Mtb pathomechanisms in the macrophages and the implications of macrophage heterogeneity and plasticity during Mtb infection.

Abstract
BACKGROUND With the aging population and rising rates of cardiovascular disease (CVD), cardiologists and cardiac surgeons are encountering a growing number of frail older patients that have complex cardiac and non-cardiac issues. Measuring frailty provides valuable prognostic information to help personalize treatment decisions. However, there is minimal evidence on multicomponent frailty interventions in this setting. The TARGET-EFT (The MulTicomponent Acute Intervention in FRail GEriatric PaTients with cardiovascular disease using the Essential Frailty Toolset) trial aims to target physical and non-physical frailty deficits to improve health-related quality of life and hospital-acquired disability in frail patients hospitalized with CVD. METHODS The TARGET-EFT trial is a single-center parallel-group randomized clinical trial in frail and pre-frail older adults ≥65 years admitted to the cardiovascular unit (CVU) at the Jewish General Hospital, Montreal, Quebec. The trial will compare usual inpatient care to a multicomponent intervention targeting physical weakness, cognitive impairment, malnutrition, and anemia. Outcomes of interest in both groups will be assessed at three time points: (1) study enrollment, (2) discharge from the CVU, and (3) 30 days after hospital discharge. CONCLUSIONS The overarching goal is to treat patients' frailty in parallel with their CVD, and in doing so, optimize patient functional losses while in-hospital and shortly thereafter. The results of this trial will inform best practices for patient-centered care in this vulnerable patient group.
