Published: May 2021

AbstractNonalcoholic fatty liver disease (NAFLD) denotes a condition with excess fat in the liver. The prevalence of NAFLD is increasing, averaging > 25% of the Western population. In 25% of the patients, NAFLD progresses to its more severe form: nonalcoholic steatohepatitis and >25% of these progress to cirrhosis following activation of inflammatory and fibrotic processes. NAFLD is associated with obesity, type 2 diabetes, and the metabolic syndrome and represents a considerable and increasing health burden. In the near future, NAFLD cirrhosis is expected to be the most common cause for liver transplantation. NAFLD patients have an increased risk of developing cardiovascular disease as well as liver-related morbidity. In addition, hepatic steatosis itself appears to represent an independent cardiovascular risk factor. In the present review, we provide an overview of the overlapping mechanisms and prevalence of NAFLD and cardiovascular disease.

AbstractChronic liver injury results in cirrhosis and end-stage liver disease (ESLD) which represents a leading cause of death worldwide, affecting people in their most productive years of life. Medical therapy can extend life, but the only definitive treatment is liver transplantation (LT). However, LT remains limited by access to quality donor organs and suboptimal long-term outcomes. The degeneration from healthy-functioning livers to cirrhosis and ESLD involves a dynamic process of hepatocyte damage, diminished hepatic function, and adaptation. However, the mechanisms responsible for deterioration of hepatocyte function and ultimately hepatic failure in man are poorly understood. We review the current understanding of cirrhosis and ESLD as a dynamic process and outline the current mechanisms associated with the development of hepatic failure from the clinical manifestations to energy adaptations, regeneration, and regulation of nuclear transcription factors. A new generation of therapeutics could target stabilization of hepatocyte differentiation and function to avoid the need for transplantation in patients with cirrhosis and ESLD.

AbstractRecovery of normal knee kinematics is critical for improving functional outcomes and patient satisfaction after total knee arthroplasty (TKA). The kinematics pattern after TKA varies from case to case, and it remains unclear how to reproduce normal knee kinematics. The present study aimed to evaluate rotational knee kinematics and soft-tissue balance using a navigation system and to assess the influence of intraoperative soft-tissue balance on the rotational knee kinematics. We evaluated 81 osteoarthritic knees treated with TKA using a posterior stabilized (50 knees) or cruciate retaining (31 knees) prosthesis. Rotational kinematics were assessed at 0, 30, 45, 60, and 90 degrees flexion angles by using a computer-assisted navigation system. Correlation between femorotibial rotational position and measured soft tissue balance was assessed by using Spearman's rank correlation coefficient. Rotational soft-tissue balance (the median angle of rotational stress) was significantly correlated with rotational kinematics (rotational axis of the femur relative to the tibia throughout the range of motion) at all measured angles after TKA. The correlation coefficients between the median angle of rotational stress and rotational kinematics were 0.97, 0.80, 0.74, 0.71, and 0.70 at 0, 30, 45, 60, and 90 degrees of flexion, respectively (p-values <0.0001 in all measured angles). The correlation coefficient increased as the knee approached full extension. Our findings suggest that soft-tissue balance is a key factor for rotational kinematics, following both cruciate-retaining and posterior-stabilized TKA.

AbstractNovel medial preserving gap technique (MPGT) focuses on medial compartment stability and allows lateral physiological laxity. This study aimed to compare the MPGT with the measured resection technique (MRT) to determine which provides better postoperative knee stability after posterior-stabilized total knee arthroplasty (PS-TKA). Primary PS-TKA, using either MPGT (n = 65) or MRT (n = 65), was performed in 130 patients with varus knee osteoarthritis. Postoperative knee stabilities at extension and flexion were assessed using varus–valgus stress radiographs and stress epicondylar view, respectively (at 1 month, 6 months, 1 year, and 3 years postoperatively). The distance between the femoral prosthesis and polyethylene insert was measured on each medial and lateral side, defined as the medial joint opening (MJO) and lateral joint opening (LJO), respectively. Decreasing MJO or LJO translated to increasing postoperative stability. The femoral external rotation angle was compared between the two surgical techniques; postoperative knee stability was also compared between the medial and lateral compartments, as well as the surgical techniques. A significant difference was found in the femoral external rotation angle between MPGT (4.2 ± 0.2 degrees) and MRT (3.6 ± 0.1 degrees, p < 0.01). Postoperative MJOs both at extension and flexion were significantly smaller than LJOs using MPGT and MRT at all time points (p < 0.05). MJOs and LJOs at extension using MPGT were significantly smaller than those when using MRT, at 1 and 3 years postoperatively (p < 0.05). Furthermore, MJOs at flexion using MPGT were significantly smaller than those when using MRT at 6 months, 1 year, and 3 years postoperatively (p < 0.05). MPGT provided higher postoperative medial knee stability than MRT both at extension and flexion, even at 3 years after PS-TKA. This suggests that this newly developed surgical technique is a more feasible option than MRT for the preservation of postoperative medial knee stability.
Clerodendrum chinense (Chinese glory bower).
Authors: Rojas-Sandoval Julissa , Acevedo-Rodríguez Pedro 
Published: May 2021

Abstract

C. chinense is a highly invasive weed in tropical and subtropical ecosystems. This species has the capacity to move into a habitat and reproduce aggressively by root suckers. C. chinense is classified as a "major weed" in Hawaii, Fiji, Western Samoa, and America Samoa (PIER, 2012) where it grows commonly along roadsides and as an ornamental shrub in gardens. This species rapidly invades pastures and plantations wherever it is planted forming dense thickets that exclude other species (Space and Flynn, 2002; Motooka et al., 2003). In the West Indies, C. chinense is included in lists of invasive species in Cuba, Puerto Rico, and US Virgin Islands (Acevedo-Rodríguez and Strong, 2012; González et al., 2012) and is classified as a widespread exotic plant in the Lesser Antilles (including Antigua, Barbados, Dominica, Grenada, Guadeloupe, Martinique, Montserrat, St. Lucia, and St. Vincent; Broome et al., 2007).

Published: May 2021

Abstract

F. convolvulus is a weedy species of gardens, cultivated fields, open habitats, orchards, non-crop areas, waste areas, and disturbed sites. It is well-adapted to a wide range of climatic conditions and soils. This species is a prolific seed producer and has the potential to produce up to 30,000 seeds/plant. Seeds can be dispersed by farm machinery, and water. It is also a common contaminant of wheat and other cereal crops. F. convolvulus is often a serious weed in cereals, vegetables and horticultural crops (FAO, 2015). Currently, it is listed as invasive in the Dominican Republic, Cuba, Australia, New Caledonia, and New Zealand (Webb et al., 1988; MacKee, 1994; Wilson, 2008; Acevedo-Rodriguez and Strong, 2012), but it is also ranked as a serious weed in 20 crops in more than 41 countries around the world (Holm et al., 1991).

Abstract

Thecaphora frezii is the causal agent of peanut smut. The disease was first reported in 1962 in wild peanuts from Aquidauana, Mato Grosso do Sul, Brazil. It was first detected in commercial crops in 1995 in the central-northern area of Córdoba province, Argentina. The prevalence of peanut smut has gradually increased. In the 2011/12 growing season, the disease was found in all production fields in Córdoba province and, two years later, it was found in all peanut production areas of Argentina. The increase in the intensity of peanut smut in Argentina has been accompanied by increasing yield losses.

Published: May 2021

Abstract

Background
Cognitive behavioral therapy for targeted-therapy related fatigue (CBT-TTF) has demonstrated preliminary efficacy in reducing fatigue in patients treated with tyrosine kinase inhibitors (TKIs) for chronic myeloid leukemia (CML).

Purpose
The aim of the current analyses was to explore whether fatigue perpetuating factors (disturbed sleep/wake cycle, dysregulated activity patterns, maladaptive cognitions about fatigue and cancer, insufficient processing of cancer and treatment, inadequate social support and interactions, heightened fear of cancer progression) changed over time in patients receiving CBT-TTF, and whether the effect of CBT-TTF on fatigue was mediated by these factors.

Methods
Secondary data analyses were conducted from a pilot randomized controlled trial. Patients with CML treated with a TKI who reported moderate to severe fatigue were randomized 2:1 to CBT-TTF delivered via FaceTime for iPad or a waitlist control condition (WLC). Self-report measures of fatigue and fatigue perpetuating factors were obtained before randomization and post-intervention (i.e., approximately 18 weeks later). Mixed model and mediation analyses using bootstrap methods were used.

Results
A total of 36 participants (CBT-TTF n = 22, WLC n = 14) who had baseline and 18-week follow-up data and attended &gt;5 sessions for CBT-TTF were included. Participants randomized to CBT-TTF reported improvements in activity (mental, physical, social, p’s ≤ .023) and cognitions (helplessness, catastrophizing, focusing on symptoms, self-efficacy, p’s ≤ .003) compared to WLC. Mental activity, social activity, self-efficacy, helplessness, and focusing on symptoms, as well as sleep and insufficient processing (avoidance) mediated the relationship between treatment group and fatigue.

Conclusions
CBT-TTF appears to improve TKI-related fatigue in CML patients through changes in behavior (sleep, activity patterns) and cognitions about fatigue and cancer. A larger randomized controlled trial is warranted to confirm these findings.

AbstractBackground and PurposeVirus mitigation strategies such as adhering to stay-at-home orders, practicing social distancing, and engaging in personal protective behaviors are central to slowing the spread of COVID-19. This population-based cohort study sought to identify sociodemographic characteristics and Health Belief Model factors that are associated with nonadherence to COVID-19 mitigation strategies with the goal of informing public health messaging campaigns.MethodsAn online population-based survey was distributed via social media over an 8-week period from April 13, 2020, to June 8, 2020.ResultsData were derived from 2,222 adults (57% female; 40% racial/ethnic minorities). Univariate analyses revealed that men, younger aged (18–30 years) and unmarried adults, and noncollege educated individuals had lower levels of perceived threat, control, and knowledge about COVID-19 (p ≤ .001). Multivariable linear regression models further revealed that male gender was significantly associated with reporting lower levels of adherence to COVID-19 mitigation strategies (p &lt; .001), and that higher levels of perceived threat, perceived control, and knowledge about how to keep oneself and others safe from COVID-19 were significantly associated with reporting higher levels of adherence to COVID-19 mitigation strategies (p &lt; .01).ConclusionsFindings suggest that public health appeals that target men, emphasize individual risk, and provide clear, consistent guidance on what individuals can do to decrease their risk for COVID-19 may be effective in motivating increased mitigation adherence.
Spring 2020 COVID-19 Surge: Prospective Relations between Demographic Factors, Personality Traits, Social Cognitions and Guideline Adherence, Mask Wearing, and Symptoms in a U.S. Sample
Authors: Milad Elizabeth , Bogg Tim 
Published: May 2021

Abstract

Background
To date, much of the research on individual difference correlates of coronavirus guideline adherence is cross-sectional, leaving prospective associations between these factors unaddressed. Additionally, investigations of prospective predictors of mask-wearing, COVID-19 symptoms, and viral testing remain wanting.

Purpose
The present study examined prospective relations between demographic factors, personality traits, social cognitions and guideline adherence, mask-wearing, symptoms, and viral testing in a U.S. sample (N = 500) during the initial surge of COVID-19 deaths in the United State between late March and early May 2020.

Methods
Guided by a disposition-belief-motivation framework, correlational analyses, and path models tested associations among baseline personality traits, guideline adherence social cognitions, health beliefs, guideline adherence and follow-up guideline adherence, mask-wearing, symptom counts, and 30-day viral testing.

Results
Modeling results showed greater baseline agreeableness, conscientiousness, and extraversion were associated with more frequent baseline guideline adherence. More liberal political beliefs, greater guideline adherence intentions, and more frequent guideline adherence at baseline predicted more frequent mask-wearing at follow-up. Sex (female), lower perceived health, and greater neuroticism at baseline predicted greater symptom counts at follow-up. Reports of viral testing were quite low (1.80%), yet were consistent with concurrent national reporting and limited availability of testing.

Conclusions
Results show how inconsistencies and politicization of health policy communication were concomitant with the effects of individual-level political beliefs on mask-wearing during the initial surge. The results further clarify how personality traits related to social responsibility (i.e., agreeableness, conscientiousness) are associated with following new norms for prescribed behaviors and how symptom reporting can be as much a marker of perceived health as emotional stability.

Abstract

Background
Few studies have comprehensively evaluated the association of depression with sleep disturbance using a controlled twin study design.

Purpose
To cross-sectionally evaluate the association of depression with both objective and subjective sleep disturbance.

Methods
We studied 246 members of the Vietnam Era Twin Registry. We measured depressive symptoms using the Beck Depression Inventory-II (BDI) and assessed major depression using structured clinical interviews. Twins underwent one-night polysomnography and 7-day actigraphy to derive measures of objective sleep and completed the Pittsburgh Sleep Quality Index for subjective sleep. Multivariable mixed-effects models were used to examine the association.

Results
Twins were all male, mostly white (97%), with a mean (SD) age of 68 (2). The mean (SD) BDI was 5.9 (6.3), and 49 (20%) met the criteria for major depression. For polysomnography, each 5-unit higher BDI, within-pair, was significantly associated with 19.7 min longer rapid eye movement (REM) sleep latency, and 1.1% shorter REM sleep after multivariable adjustment. BDI was not associated with sleep architecture or sleep-disordered breathing. For actigraphy, a higher BDI, within-pair, was significantly associated with lower sleep efficiency, more fragmentation and higher variability in sleep duration. BDI was associated with almost all dimensions of self-reported sleep disturbance. Results did not differ by zygosity, and remained consistent using major depression instead of BDI and were independent of the presence of comorbid posttraumatic stress disorder and antidepressant use.

Conclusions
Depression is associated with REM sleep disruption in lab and sleep fragmentation and sleep variability at home, but not with sleep architecture or sleep-disordered breathing.
DITHER: an algorithm for Defining IntraTumor Heterogeneity based on EntRopy
Authors: Li Lin , Chen Canping , Wang Xiaosheng 
Published: May 2021

AbstractIntratumor heterogeneity (ITH) is associated with tumor development, prognosis, immune evasion and therapeutic effects. We proposed the Defining ITH based on EntRopy (DITHER) algorithm for evaluating ITH. We first evaluated the entropies of somatic mutation profiles and copy number alteration (CNA) profiles in a tumor, respectively, and defined their average as the ITH level for the tumor. Using DITHER, we analyzed 33 cancer types from The Cancer Genome Atlas (TCGA) program. We demonstrated that the ITH defined by DITHER had the typical properties of ITH, namely its strong correlations with tumor progression, unfavorable phenotype, genomic instability and immune evasion. Compared with two other ITH evaluation methods: MATH and PhyloWGS, the DITHER ITH had more prominent characteristics of ITH. Moreover, different from MATH and PhyloWGS, DITHER scores were positively correlated with tumor purity, suggesting that DITHER tends to capture the ITH between tumor cells. Interestingly, microsatellite instability (MSI)-high tumors had significantly lower DITHER scores than microsatellite stability (MSS)/MSI-low tumors, although the former had significantly higher tumor mutation loads than the latter. It suggests that the hypermutability of MSI is homogeneous between different cellular populations in bulk tumors. The DITHER ITH may provide novel insights into tumor biology and potential clinical applications.
More practical differentially private publication of key statistics in GWAS
Authors: Yamamoto Akito , Shibuya Tetsuo 
Published: May 2021

Abstract Motivation: Analyses of datasets that contain personal genomic information are very important for revealing associations between diseases and genomes. Genome-wide association studies, which are large-scale genetic statistical analyses, often involve tests with contingency tables. However, if the statistics obtained by these tests are made public as they are, sensitive information of individuals could be leaked. Existing studies have proposed privacy-preserving methods for statistics in the χ2 test with a 3 × 2 contingency table, but they do not cover all the tests used in association studies. In addition, existing methods for releasing differentially private P-values are not practical.Results: In this work, we propose methods for releasing statistics in the χ2 test, the Fisher’s exact test and the Cochran–Armitage’s trend test while preserving both personal privacy and utility. Our methods for releasing P-values are the first to achieve practicality under the concept of differential privacy by considering their base 10 logarithms. We make theoretical guarantees by showing the sensitivity of the above statistics. From our experimental results, we evaluate the utility of the proposed methods and show appropriate thresholds with high accuracy for using the private statistics in actual tests.Availability and implementationA python implementation of our experiments is available at https://github.com/ay0408/DP-statistics-GWAS.Supplementary informationSupplementary data are available at Bioinformatics Advances online.
Brighter is darker: the Hamilton–Zuk hypothesis revisited in lizards
Authors: Megía-Palma Rodrigo , Barrientos Rafael , Gallardo Manuela , Martínez Javier , Merino Santiago 
Published: May 2021

Abstract
Several studies of lizards have made an erroneous interpretation of negative relationships between spectral brightness and parasite load, and thus provided misleading support for the Hamilton–Zuk hypothesis (HZH). The HZH predicts that infected hosts will produce poorer sexual ornamentation than uninfected individuals as a result of energetic trade-offs between immune and signalling functions. To test whether there is a negative relationship between spectral brightness and pigment content in the skin of lizards, we used spectrophotometry to quantify the changes in spectral brightness of colour patches of two species after chemically manipulating the contents of orange, yellow and black pigments in skin samples. Carotenoids were identified using high-performance liquid chromatography. In addition, we compared the spectral brightness in the colour patches of live individuals with differential expression of nuptial coloration. Overall, the analyses demonstrated that the more pigmented the colour patch, the darker the spectrum. We provide a comprehensive interpretation of how variation in pigment content affects the spectral brightness of the colour patches of lizards. Furthermore, we review 18 studies of lizards presenting 24 intraspecific tests of the HZH and show that 14 (58%) of the tests do not support the hypothesis.
