Expanding sacrificially printed microfluidic channel-embedded paper devices for construction of volumetric tissue models in vitro

We report a method for expanding microchannel-embedded paper devices using a precisely controlled gas-foaming technique for the generation of volumetric tissue models in vitro. We successfully fabricated hollow, perfusable microchannel patterns contained in a densely entangled network of bacterial cellulose nanofibrils using matrix-assisted sacrificial three-dimensional printing, and demonstrated the maintenance of their structural integrity after gas-foaming-enabled expansion in an aqueous solution of NaBH4. The resulting expanded microchannel-embedded paper devices showed multilayered laminar structures with controllable thicknesses as a function of both NaBH4 concentration and expansion time. With expansion, the thickness and porosity of the bacterial cellulose network were significantly increased. As such, cellular infiltration was promoted comparing to as-prepared, non-expanded devices. This simple technique enables the generation of truly volumetric, cost-effective human-based tissue models, such as vascularized tumor models, for potential applications in preclinical drug screening and personalized therapeutic selection.
Serial Assessment of Depression and Anxiety by Patients and Providers in Women Receiving Chemotherapy for Early Breast Cancer.

BACKGROUND Depression and anxiety are common in patients with breast cancer and associated with worse quality of life and treatment outcomes. Yet, these symptoms are often underrecognized and undermanaged in oncology practice. The objective of this study was to describe depression and anxiety severity and associated patient factors during adjuvant or neoadjuvant chemotherapy in women with early breast cancer using repeated single-item reports. MATERIALS AND METHODS Depression and anxiety were measured from consecutive patients and their clinicians during chemotherapy infusion visits. Associations between psychiatric symptoms and patient characteristics were assessed using Fisher's exact tests for categorical variables and t tests for continuous variables. The joint relationship of covariates significant in unadjusted analyses was evaluated using log-binomial regression. Cohen's kappa was used to assess agreement between patient- and clinician-reported symptoms. RESULTS In a sample of 256 patients, 26% reported at least moderately severe depression, and 41% reported at least moderately severe anxiety during chemotherapy, representing a near doubling in the prevalence of these symptoms compared with before chemotherapy. Patient-provider agreement was fair (depression: κ = 0.31; anxiety: κ = 0.28). More severe psychiatric symptoms were associated with being unmarried, having worse function, endorsing social activity limitations, using psychotropic medications, and having a mental health provider. In multivariable analysis, social activity limitations were associated with more severe depression (relative risk [RR], 2.17; 95% confidence interval [CI], 1.36-3.45) and anxiety (RR, 1.48; 95% CI, 1.05-2.09). CONCLUSION Oncologists frequently underestimate patients' depression and anxiety and should consider incorporating patient-reported outcomes to enhance monitoring of mental health symptoms. IMPLICATIONS FOR PRACTICE In this sample of 256 patients with breast cancer, depression and anxiety, measured using single-item toxicity reports completed by patients and providers, were very common during adjuvant or neoadjuvant chemotherapy. Patient-reported depression and anxiety of at least moderate severity were associated with multiple objective indicators of psychiatric need. Unfortunately, providers underrecognized the severity of their patients' mental health symptoms. The use of patient-reported, single-item toxicity reports can be incorporated into routine oncology practice and provide clinically meaningful information regarding patients' psychological health.
Clinical Evidence for Targeting NAD Therapeutically

Nicotinamide adenine dinucleotide (NAD) pharmacology is a promising class of treatments for age-related conditions that are likely to have a favorable side effect profile for human use, given the widespread use of the NAD precursor vitamin B3 supplements. However, despite several decades of active investigation and numerous possible biochemical mechanisms of action suggested, only a small number of randomized and adequately powered clinical trials of NAD upregulation as a therapeutic strategy have taken place. We conducted a systematic review of the literature, following the PRISMA guidelines, in an attempt to determine whether or not the human clinical trials performed to date support the potential benefits of NAD supplementation in a range of skin, metabolic and age-related conditions. In addition, we sought medical indications that have yielded the most promising results in the limited studies to date. We conclude that promising, yet still speculative, results have been reported for the treatment of psoriasis and enhancement of skeletal muscle activity. However, further trials are required to determine the optimal method of raising NAD levels, identifying the target conditions, and comparisons to the present standard of care for these conditions. Lastly, pharmacological methods that increase NAD levels should also be directly compared to physiological means of raising NAD levels, such as exercise programs and dietary interventions that are tailored to older individuals, and which may be more effective.
Microstructural, Tribology and Corrosion Properties of Optimized Fe3O4-SiC Reinforced Aluminum Matrix Hybrid Nano Filler Composite Fabricated through Powder Metallurgy Method

Hybrid reinforcement’s novel composite (Al-Fe3O4-SiC) via powder metallurgy method was successfully fabricated. In this study, the aim was to define the influence of SiC-Fe3O4 nanoparticles on microstructure, mechanical, tribology, and corrosion properties of the composite. Various researchers confirmed that aluminum matrix composite (AMC) is an excellent multifunctional lightweight material with remarkable properties. However, to improve the wear resistance in high-performance tribological application, hardening and developing corrosion resistance was needed; thus, an optimized hybrid reinforcement of particulates (SiC-Fe3O4) into an aluminum matrix was explored. Based on obtained results, the density and hardness were 2.69 g/cm3, 91 HV for Al-30Fe3O4-20SiC, after the sintering process. Coefficient of friction (COF) was decreased after adding Fe3O4 and SiC hybrid composite in tribology behaviors, and the lowest COF was 0.412 for Al-30Fe3O4-20SiC. The corrosion protection efficiency increased from 88.07%, 90.91%, and 99.83% for Al-30Fe3O4, Al-15Fe3O4-30SiC, and Al-30Fe3O4-20SiC samples, respectively. Hence, the addition of this reinforcement (Al-Fe3O4-SiC) to the composite shows a positive outcome toward corrosion resistance (lower corrosion rate), in order to increase the durability and life span of material during operation. The accomplished results indicated that, by increasing the weight percentage of SiC-Fe3O4, it had improved the mechanical properties, tribology, and corrosion resistance in aluminum matrix. After comparing all samples, we then selected Al-30Fe3O4-20SiC as an optimized composite.
Intraperitoneal rupture of the hydatid cyst disease: Single-center experience and literature review.

BACKGROUND The primary aim of this study was to present our experience on intraperitoneal rupture of the hydatid cyst in guidance of literature data. METHODS Demographical, clinical, radiological and postoperative follow-up data of 29 patients who underwent surgical treatment in our institution with an indication of intraperitoneal rupture of the hydatid cyst from January 2003 to July 2020 were analysed retropectively. RESULTS Among the 29 patients with an age range of from 16 to 79 years ( median= 39, IQR=25.5), 16 were male (55.2%) and 13 were female (44.8%). Intraperitoneal rupture of the hydatid cyst was spontaneous in 21 (72.4%), traumatic in 7 (24.13%) (2 of them were iatrogenic) and was due to shotgun in one patient. Vast majority of the patients were admitted to the emergency department in the first 24 hours after the onset of sign and symptoms. WBC varied from 8.600 to 30.900/mm3 (median=12.100, IQR=5.7). Ruptured cysts were localised in liver (n=25, 86.2%), in spleen (n=2, 6.89%) or in pelvis (n=2, 6.89%) and diameter varied from 40 to 200 mm (median= 90, IQR=50). Among the cysts ruptured in liver, 19 (76%) of them were localised in right lobe. Among the ruptured cysts of liver, 20 (80%) of them underwent conservative surgery (partial pericystectomy etc), remaining 5 patients (20%) underwent a radical surgical treatment (pericystectomy etc). A biliary orifice was diagnosed during surgical exploration in either cyst cavity or cut surface of liver in 12 (48%) of the patients. Patients with a dilated common bile duct or a visible biliary duct orifice in cystic cavity underwent common bile duct exploration and T-tube drainage procedure (n=6, 24%). One patient died on postoperative day one, due to cardiopulmonary complications secondary to cyst rupture. All along the postopeartive follow-up of median 1416 days, seven (24.1%) patients were diagnosed for diseased recurrence. CONCLUSION Intraperitoneal rupture of the hydatid cyst is a life-threatening complication of hydatid cyst disease, for which diagnosis without delay and timing of surgical treatment is essential. Anaphylactic shock cases require rapidly initiation of medical treatment against allergic reactions. Despite scolocidal agents, vesicular spread into peritoneal cavity account for the major risk factor for disease recurrence. Hence, abdominal cavity should be explored cautiously.
Exhaustion of tumour‐infiltrating T‐cell receptor repertoire diversity is an age‐dependent indicator of immunological fitness independently predictive of clinical outcome in Burkitt lymphoma

Burkitt lymphoma (BL) is an aggressive B‐cell‐malignancy derived from germinal‐centre B‐cells. Curative therapy traditionally requires intensive immunochemotherapy. Recently, immuno‐oncological approaches, modulating the T‐cell tumour response, were approved for the treatment of a variety of malignancies. The architecture of the tumour‐infiltrating T‐cell receptor (TCR) repertoire in BL remains insufficiently characterized. We therefore performed a large‐scale, next‐generation sequencing study of the complimentary‐determining region (CDR)‐3 region of the TCRβ chain repertoire in a large cohort of all epidemiological subtypes of BL (n = 82) and diffuse large B‐cell lymphoma (DLBCL; n = 34). Molecular data were subsequently assessed for correlation with clinical outcome. Our investigations revealed an age‐dependent immunoprofile in BL as in DLBCL. Moreover, we found several public clonotypes in numerous patients suggestive of shared tumour neoantigen selection exclusive to BL and distinct from DLBCL regardless of Epstein–Barr virus and/or human immunodeficiency virus status. Compared with baseline, longitudinal analysis unveiled significant repertoire restrictions upon relapse (P = 0·0437) while productive TCR repertoire clonality proved to be a useful indicator of both overall and progression‐free‐survival [OS: P = 0·0001; hazard ratio (HR): 6·220; confidence interval (CI): 2·263–11·78; PFS: P = 0·0025; HR: 3·086; CI: 1·555–7·030]. Multivariate analysis confirmed its independence from established prognosticators, including age at diagnosis and comorbidities. Our findings establish the clinical relevance of the architecture and clonality of the TCR repertoire and its age‐determined dynamics in BL.
Exploring Health Literacy in Individuals with Alcohol Addiction: A Mixed Methods Clinical Study

This mixed methods research paper explores health literacy (HL) in individuals with alcohol addiction by using the 47-item version of the European Health Literacy Survey Questionnaire (HLS-EU-Q47) and semi-structured interviews concerning health-related competencies (access, understand, appraise, and apply health information), and determines the limitations of the HLS-EU-Q47 when used under specific conditions of clinical practice. The questionnaire survey and the interviews were conducted with individuals of different health literacy levels who were undergoing inpatient alcohol addiction treatment. The findings indicate that individuals with alcohol addiction might require different types of health information according to their health literacy level in terms of quantity and quality of information to recover from alcohol addiction and improve their overall health. The implications for the clinical practice of addiction treatment as well as recommendations for national and regional policy are also discussed.
Laterality in Children: Evidence for Task-Dependent Lateralization of Motor Functions

The behavioral preference for the use of one side of the body starts from pre-natal life and prompt humans to develop motor asymmetries. The type of motor task completed influences those functional asymmetries. However, there is no real consensus on the occurrence of handedness during developmental ages. Therefore, we aimed to determine which motor asymmetries emerged differently during childhood. A total sample of 381 children in grades 1 to 5 (6–11 years old) of primary school were recruited and tested for two fine coordination tasks (Floppy, led by dexterity, and Thumb, led by speed-dominated skills) and handgrip strength (HS). Data about their handedness, footedness and sports participation were also collected. Children performed better with their dominant side, especially for the Floppy and HS tests. The asymmetries were more marked in right-handed children and did not differ by age, gender or type of sport. Our findings support the thesis of a functional lateralization in complex coordinative tasks and in maximal strength during developmental ages. Furthermore, our findings extend the evidence of a stronger lateralization in right-handed individuals, demonstrating it at a functional level in primary school children performing motor tasks. Fine motor skills allow a “fine” understanding of developmental trajectories of lateralized behavior.
Wolbachia affects reproduction in the spider mite Tetranychus truncatus (Acari: Tetranychidae) by regulating chorion protein S38‐like and Rop

Wolbachia‐induced reproductive regulation in hosts has been used to control pest populations, but little is known about the molecular mechanism underlying Wolbachia regulation of host genes. Here, reproductive regulation by Wolbachia in the spider mite Tetranychus truncatus was studied at the molecular level. Infection with Wolbachia resulted in decreasing oviposition and cytoplasmic incompatibility in T. truncatus. Further RNA‐seq revealed genes regulated by Wolbachia in T. truncatus. Real‐time quantitative polymerase chain reaction (qPCR) showed that genes, including chorion protein S38‐like and Rop were down‐regulated by Wolbachia. RNA interference (RNAi) of chorion protein S38‐like and Rop in Wolbachia‐uninfected T. truncatus decreased oviposition, which was consistent with Wolbachia‐induced oviposition decrease. Interestingly, suppressing Rop in Wolbachia‐infected T. truncatus led to increased Wolbachia titres in eggs; however, this did not occur after RNAi of chorion protein S38‐like. This is the first study to show that chorion protein S38‐like and Rop facilitate Wolbachia‐mediated changes in T. truncatus fertility. In addition, RNAi of Rop turned the body colour of Wolbachia‐uninfected T. truncatus black, which indicates that the role of Rop is not limited to the reproductive regulation of T. truncatus.
Glycolytic and immunological alterations in human U937 monocytes in response to H1N1 infection

We monitored changes that took place in glycolytic enzymes, the pyruvate end product of glycolysis, tumor necrosis factor α (TNFα), and toll‐like receptors (TLRs) both at the transcriptional and translational levels upon direct interaction between PR8‐H1N1 and the human monocytes U937 in vitro system. U937 were first treated with H1N1 infectious viral particles or phorbol‐12‐myristate‐13‐acetate (PMA) or left untreated and later infected with the H1N1 virus. Levels of phosphofructokinase 1 (PFK1) and pyruvate were biochemically quantified. In addition, levels of TNFα, TLR3, and TLR7 were measured by ELISA. The transcriptional profiles of PFKs, inflammatory cytokines, TLR3 and TLR7 were relatively quantified by qRT‐PCR. The results generally revealed significant changes in both the transcriptional and translational profiles of the studied biochemical and immunological parameters upon influenza infection in a time‐dependent manner. In conclusion, H1N1 infection triggers transcriptional and translational changes in immortalized human monocytes, which might serve as markers for infection subject for further validation for their specificities.
Prevalence of Multiple Chronic Conditions Among US Adults, 2018

This analysis provides prevalence estimates of diagnosed single and multiple (≥2) chronic conditions among the noninstitutionalized, civilian US adult population. Data from the 2018 National Health Interview Survey (NHIS) were used to estimate percentages for US adults by selected demographic characteristics. More than half (51.8%) of adults had at least 1 of 10 selected diagnosed chronic conditions (arthritis, cancer, chronic obstructive pulmonary disease, coronary heart disease, current asthma, diabetes, hepatitis, hypertension, stroke, and weak or failing kidneys), and 27.2% of US adults had multiple chronic conditions.
Antibiogram, Prevalence of OXA Carbapenemase Encoding Genes, and RAPD-Genotyping of Multidrug-Resistant Acinetobacter baumannii Incriminated in Hidden Community-Acquired Infections

Acinetobacter spp. has gained fame from their ability to resist difficult conditions and their constant development of antimicrobial resistance. This study aimed to investigate the prevalence, susceptibility testing, OXA carbapenemase-encoding genes, and RAPD-genotyping of multidrug resistant Acinetobacter baumannii incriminated in hidden community-acquired infections in Egypt. The antimicrobial susceptibility testing was assessed phenotypically using Kirby–Bauer disk diffusion method. Also, Modified-Hodge test (MHT) was carried out to detect the carbapenemases production. Multiplex-PCR was used to detect the carbapenemase-encoding genes. Furthermore, the genetic relationship among the isolated strains was investigated using RAPD fingerprinting. The bacteriological examination revealed that, out of 200 Gram-negative non-fermentative isolates, 44 (22%) were identified phenotypically and biochemically as Acinetobacter spp. and 23 (11.5%) were molecularly confirmed as A. baumannii. The retrieved A. baumannii strains were isolated from urine (69%), sputum (22%), and cerebrospinal fluid (csf) (9%). The isolated A. baumannii strains exhibited multidrug resistance and the production rates of carbapenemases were 56.5, 60.9, and 78.3% with meropenem, imipenem, and ertapenem disks, respectively. The blaOXA-24-like genes were the most predominant among the tested strains (65.2%), followed by blaOXA-23 (30.4%) and blaOXA-58 (17.4%), in addition, the examined strains are harbored IMP, VIM, and NDM genes with prevalence of 60.9, 43.5, and 13%, respectively, while KPC and GES genes were not detected. RAPD-PCR revealed that the examined strains are clustered into 11 different genotypes at ≥90% similarity. Briefly, to the best of our knowledge, this study is the first report concerning community-associated A. baumannii infections in Egypt. The high prevalence of hidden multidrug-resistant (MDR) and extensively drug-resistant (XDR) A. baumannii strains associated with non-hospitalized patients raises an alarm for healthcare authorities to set strict standards to control the spread of such pathogens with high rates of morbidity and mortality.
StainedView: Variable-Intensity Light-Attenuation Display with Cascaded Spatial Color Filtering for Improved Color Fidelity

We present StainedView, an optical see-through display that spatially filters the spectral distribution of light to form an image with improved color fidelity. Existing light-attenuation displays have limited color fidelity and contrast, resulting in a degraded appearance of virtual images. To use these displays to present virtual images that are more consistent with the real world, we require three things: intensity modulation of incoming light, spatial color filtering with narrower bandwidth, and appropriate light modulation for incoming light with an arbitrary spectral distribution. In StainedView, we address the three requirements by cascading two phase-only spatial light modulators (PSLMs), a digital micromirror device, and polarization optics to control both light intensity and spectrum distribution. We show that our design has a 1.8 times wider color gamut fidelity (75.8% fulfillment of sRGB color space) compared to the existing single-PSLM approach (41.4%) under a reference white light. We demonstrated the design with a proof-of-concept display system. We further introduce our optics design and pixel-selection algorithm for the given light input, evaluate the spatial color filter, and discuss the limitation of the current prototype.
Circulating miR‐155, let‐7c, miR‐21, and PTEN levels in differential diagnosis and prognosis of idiopathic granulomatous mastitis and breast cancer

This study investigates whether the circulating miR‐155, let‐7c, miR‐21, and PTEN levels to be used in the differential diagnosis of patients with idiopathic granulomatous mastitis (IGM) and breast cancer (BC). Forty‐five patients with BC, 50 patients with IGM, and 48 healthy volunteers were included in the study. Serum miR‐21 expression was significantly higher in BC (fold change = 2.42) and IGM group (fold change = 1.33) compared to control (p < .001). Serum miR‐155 and let‐7c expression levels were significantly lower in both groups compared to the control group (p < .001). miR‐21 expression in BC was significantly higher than IGM (fold change = 1.976; p < .001). PTEN levels in BC were significantly higher than IGM (p < .001) and significantly lower than the control group (p < .001); the IGM group was significantly lower than the control group (p < .001). In addition to radiological data, serum miR‐21 and PTEN levels may be noninvasive biomarkers that can help differentiate IGM from BC. The results of the study will lead to future studies in the differential diagnosis of IGM and BC.
