Authors: Raniga Sumit , Cadman Joseph , Dabirrahmani Danè , Bui David , Appleyard Richard , Bokor Desmond 
Published: January 2021

Background: Suture pullout during rehabilitation may result in loss of tension in the inferior glenohumeral ligament (IGHL) and contribute to recurrent instability after capsular plication, performed with or without labral repair. To date, the suture pullout strength in the IGHL is not well-documented. This may contribute to recurrent instability. Purpose/Hypothesis: A cadaveric biomechanical study was designed to investigate the suture pullout strength of sutures in the IGHL. We hypothesized that there would be no significant variability of suture pullout strength between specimens and zones. Additionally, we sought to determine the impact of early mobilization on sutures in the IGHL at time zero. We hypothesized that capsular plication sutures would fail under low load. Study Design: Descriptive laboratory study. Methods: Seven fresh-frozen cadaveric shoulders were dissected to isolate the IGHL complex, which was then divided into 18 zones. Sutures in these zones were attached to a linear actuator, and the resistance to suture pullout was recorded. A suture pullout strength map of the IGHL was constructed. These loads were used to calculate the load applied at the hand that would initiate suture pullout in the IGHL. Results: Mean suture pullout strength for all specimens was 61.6 ± 26.1 N. The maximum load found to cause suture pullout through tissue was found to be low, regardless of zone of the IGHL. Calculations suggest that an external rotation force applied to the hand of only 9.6 N may be sufficient to tear capsular sutures at time zero. Conclusion: This study did not provide clear evidence of desirable locations for fixation in the IGHL. However, given the low magnitude of failure loads, the results suggest the timetable for initiation of range-of-motion exercises should be reconsidered to prevent suture pullout through the IGHL. Clinical Relevance: From this biomechanical study, the magnitude of force required to cause suture pullout through the IGHL is met or surpassed by normal postoperative early range-of-motion protocols.

Published: January 2021

Introduction: Linear morphea is an inflammatory condition that is often treated with systemic glucocorticoids and methotrexate, with mycophenolate mofetil being used as an alternative agent. However, there are few published reports on beneficial effect of abatacept for refractory disease. We present a case of a woman in her 30s who presented with linear morphea on her scalp, with a notable response following the addition of subcutaneous abatacept. Methods: Computational analysis was performed comparing the immune cell scores of skin biopsies from five morphea skin biopsies from three additional unique patients and 15 healthy control skin biopsies. Value of p < 0.05 was considered statistically significant. Results: Immune cell scores demonstrated a statistically significant enrichment of activated CD4 memory T cells, M1 macrophages, monocytes, and memory B cells comparing skin biopsies of morphea versus healthy controls (p < 0.05 for all). Discussion: Abatacept may be considered for recalcitrant cases of morphea. Our computational analysis supports a well-designed study is needed to assess abatacept as first-line therapy.

Published: January 2021

ObjectiveMolecular similarities of grass pollen antigens have led to the view that cross‐reactivity exists within members of the Pooideae subfamily of grasses. This has resulted in testing for only the most antigenically representative member of Pooideae, Timothy grass (Phleum pratense), despite little literature to support the claim that Phleum is the most representative member or that in vitro cross‐reactivity correlates with in vivo cross‐reactivity. The aim of the study was to determine if patients with allergic rhinitis symptoms and positive skin prick test results to meadow fescue (Festuca pratensis) also have positive results to Timothy grass.Study DesignRetrospective cross‐sectional study.SettingTertiary care center in middle Missouri.MethodsA retrospective chart review identified patients ≥12 years old with a diagnosis of allergic rhinitis who underwent skin prick testing between March 2016 and July 2018, by using a search with CPT code 95004 (Current Procedural Terminology). Positive skin prick test results were based on wheal produced ≥3 mm than the negative control.ResultsAfter review of 2182 charts, 1587 patients met criteria to test for Phleum and Festuca. In total, 1239 patients had a positive result for Phleum or Festuca. Of these, 479 (38.6%) tested positive for Festuca alone, while 342 (27.6%) and 418 (33.7%) tested positive for Phleum alone and Phleum+Festuca, respectively.ConclusionClinical cross‐reactivity among Pooideae members may not be as complete as traditionally thought. P pratense may not be the most antigenically representative subfamily member, and other grasses may need to be included in skin prick testing.

Published: January 2021

Objective: The purpose of our study was to determine the 4-year visual and anatomic outcomes of intravitreal aflibercept treatment for neovascular age-related macular degeneration (AMD) using a treat-and-extend (TAE) regimen. Methods: We retrospectively reviewed the medical records of 39 patients with neovascular AMD who were treated continuously with intravitreal aflibercept injections using the TAE regimen for at least 4 years. The outcome measures were the best-corrected visual acuity (BCVA) and central macular thickness (CMT) on spectral-domain optical coherence tomography. The BCVAs were measured as decimal values and converted to the corresponding Early Treatment Diabetic Retinopathy Study (ETDRS) letter scores for statistical analysis. The Wilcoxon signed-rank test was used to compare the differences in BCVAs and CMTs. Results: The mean ETDRS letter scores improved significantly from 63.9 at baseline to 70.4, 67.8, 67.2, and 67.3 at 1, 2, 3, and 4 years, respectively. The mean baseline CMT was 380 µm, which decreased significantly to 229, 231, 221, and 210 µm at 1, 2, 3, and 4 years, respectively. The mean numbers of injections were 7.9, 6.0, 5.5, and 5.4 at 1, 2, 3, and 4 years, respectively. The percentages of patients with a treatment interval of 12 weeks or more were 46.2%, 46.2%, 43.6%, and 46.2% at 1, 2, 3, and 4 years, respectively. At year 4, 30.8% of the patients had a treatment interval of 7 weeks or less, whereas 25.6% had 16 weeks or more. Conclusion: Intravitreal aflibercept TAE treatment may be an effective and efficient method for treating patients with neovascular AMD up to 4 years of follow-up. The TAE regimen is a potential tool to optimize appropriate treatment intervals, avoiding both undertreatment and overtreatment of neovascular AMD.

Abstract
Axicabtagene ciloleucel (axi-cel) is a chimeric antigen receptor (CAR) T-cell therapy for relapsed or refractory large B-cell lymphoma (LBCL). This study evaluated whether immune dysregulation, present before CAR T-cell therapy, was associated with treatment failure. Tumor expression of interferon (IFN) signaling, high blood levels of monocytic myeloid-derived suppressor cells (M-MDSCs), and high blood interleukin-6 and ferritin levels were each associated with a lack of durable response. Similar to other cancers, we found that in LBCL tumors, IFN signaling is associated with the expression of multiple checkpoint ligands, including programmed cell death–ligand 1, and these were higher in patients who lacked durable responses to CAR-T therapy. Moreover, tumor IFN signaling and blood M-MDSCs associated with decreased axi-cel expansion. Finally, patients with high tumor burden had higher immune dysregulation with increased serum inflammatory markers and tumor IFN signaling. These data support that immune dysregulation in LBCL promotes axi-cel resistance via multiple mechanistic programs: insufficient axi-cel expansion associated with both circulating M-MDSC and tumor IFN signaling, which also gives rise to expression of immune checkpoint ligands.
Accucopy: accurate and fast inference of allele-specific copy number alterations from low-coverage low-purity tumor sequencing data
Authors: Fan Xinping , Luo Guanghao , Huang Yu S. 
Published: January 2021

Abstract
Background
Copy number alterations (CNAs), due to their large impact on the genome, have been an important contributing factor to oncogenesis and metastasis. Detecting genomic alterations from the shallow-sequencing data of a low-purity tumor sample remains a challenging task.

Results
We introduce Accucopy, a method to infer total copy numbers (TCNs) and allele-specific copy numbers (ASCNs) from challenging low-purity and low-coverage tumor samples. Accucopy adopts many robust statistical techniques such as kernel smoothing of coverage differentiation information to discern signals from noise and combines ideas from time-series analysis and the signal-processing field to derive a range of estimates for the period in a histogram of coverage differentiation information. Statistical learning models such as the tiered Gaussian mixture model, the expectation–maximization algorithm, and sparse Bayesian learning were customized and built into the model. Accucopy is implemented in C++ /Rust, packaged in a docker image, and supports non-human samples, more at http://www.yfish.org/software/.

Conclusions
We describe Accucopy, a method that can predict both TCNs and ASCNs from low-coverage low-purity tumor sequencing data. Through comparative analyses in both simulated and real-sequencing samples, we demonstrate that Accucopy is more accurate than Sclust, ABSOLUTE, and Sequenza.
Multi-trait GWAS using imputed high-density genotypes from whole-genome sequencing identifies genes associated with body traits in Nile tilapia
Authors: Yoshida Grazyella M. , Yáñez José M. 
Published: January 2021

Abstract
Background
Body traits are generally controlled by several genes in vertebrates (i.e. polygenes), which in turn make them difficult to identify through association mapping. Increasing the power of association studies by combining approaches such as genotype imputation and multi-trait analysis improves the ability to detect quantitative trait loci associated with polygenic traits, such as body traits.

Results
A multi-trait genome-wide association study (mtGWAS) was performed to identify quantitative trait loci (QTL) and genes associated with body traits in Nile tilapia (Oreochromis niloticus) using genotypes imputed to whole-genome sequences (WGS). To increase the statistical power of mtGWAS for the detection of genetic associations, summary statistics from single-trait genome-wide association studies (stGWAS) for eight different body traits recorded in 1309 animals were used. The mtGWAS increased the statistical power from the original sample size from 13 to 44%, depending on the trait analyzed. The better resolution of the WGS data, combined with the increased power of the mtGWAS approach, allowed the detection of significant markers which were not previously found in the stGWAS. Some of the lead single nucleotide polymorphisms (SNPs) were found within important functional candidate genes previously associated with growth-related traits in other terrestrial species. For instance, we identified SNP within the α1,6-fucosyltransferase (FUT8), solute carrier family 4 member 2 (SLC4A2), A disintegrin and metalloproteinase with thrombospondin motifs 9 (ADAMTS9) and heart development protein with EGF like domains 1 (HEG1) genes, which have been associated with average daily gain in sheep, osteopetrosis in cattle, chest size in goats, and growth and meat quality in sheep, respectively.

Conclusions
The high-resolution mtGWAS presented here allowed the identification of significant SNPs, linked to strong functional candidate genes, associated with body traits in Nile tilapia. These results provide further insights about the genetic variants and genes underlying body trait variation in cichlid fish with high accuracy and strong statistical support.
Post-status epilepticus treatment with the Fyn inhibitor, saracatinib, improves cognitive function in mice
Authors: Luo Xin-Ming , Zhao Jing , Wu Wen-Yue , Fu Jie , Li Zheng-Yu , Zhang Ming , Lu Jie 
Published: January 2021

AbstractBackgroundStatus epilepticus (SE) is a life-threatening neurological disorder. The hippocampus, as an important area of the brain that regulates cognitive function, is usually damaged after SE, and cognitive deficits often result from hippocampal neurons lost after SE. Fyn, a non-receptor Src family of tyrosine kinases, is potentially associated with the onset of seizure. Saracatinib, a Fyn inhibitor, suppresses epileptogenesis and reduces epileptiform spikes. However, whether saracatinib inhibits cognitive deficits after SE is still unknown.MethodsIn the present study, a pilocarpine-induced SE mouse model was used to answer this question by using the Morris water maze and normal object recognition behavioral tests.ResultsWe found that saracatinib inhibited the loss in cognitive function following SE. Furthermore, we found that the number of hippocampal neurons in the saracatinib treatment group was increased, when compared to the SE group.ConclusionsThese results showed that saracatinib can improve cognitive functions by reducing the loss of hippocampal neurons after SE, suggesting that Fyn dysfunction is involved in cognitive deficits after SE, and that the inhibition of Fyn is a possible treatment to improve cognitive function in SE patients.

Published: January 2021

Abstract
Background
‘Regal Splendour’ (Hosta variety) is famous for its multi-color leaves, which are useful resources for exploring chloroplast development and color changes. The expressions of chlorophyll biosynthesis-related genes (HrHEMA, HrPOR and HrCAO) in Hosta have been demonstrated to be associated with leaf color. Herein, we isolated, sequenced, and analyzed HrHEMA, HrPOR and HrCAO genes. Subcellular localization was also performed to determine the location of the corresponding enzymes. After plasmid construction, virus-induced gene silencing (VIGS) was carried out to reduce the expressions of those genes. In addition, HrHEMA-, HrPOR- and HrCAO-overexpressing tobacco plants were made to verify the genes function. Changes of transgenic tobacco were recorded under 2000 lx, 6000 lx and 10,000 lx light intensity. Additionally, the contents of enzyme 5-aminolevulinic acid (5-ALA), porphobilinogen (PBG), chlorophyll a and b (Chla and Chlb), carotenoid (Cxc), superoxide dismutase (SOD), peroxidase (POD), malondialdehyde (MDA), proline (Pro) and catalase (CAT) under different light intensities were evaluated.

Results
The silencing of HrHEMA, HrPOR and HrCAO genes can induce leaf yellowing and chloroplast structure changes in Hosta. Specifically, leaves of Hosta with HrCAO silencing were the most affected, while those with HrPOR silencing were the least affected. Moreover, all three genes in tobacco were highly expressed, whereas no expression was detected in wild-type (WT). However, the sensitivities of the three genes to different light intensities were different. The highest expression level of HrHEMA and HrPOR was detected under 10,000 lx of illumination, while HrCAO showed the highest expression level under 6000 lx. Lastly, the 5-ALA, Chla, Cxc, SOD, POD, MDA, Pro and CAT contents in different transgenic tobaccos changed significantly under different light intensities.

Conclusion
The overexpression of these three genes in tobacco enhanced photosynthesis by accumulating chlorophyll content, but the influential level varied under different light intensities. Furthermore, HrHEMA-, HrPOR- and HrCAO- overexpressing in tobacco can enhance the antioxidant capacity of plants to cope with stress under higher light intensity. However, under lower light intensity, the antioxidant capacity was declined in HrHEMA-, HrPOR- and HrCAO- overexpressing tobaccos.

Authors: Mortazavi Forough , Mehrabadi Maryam , KiaeeTabar Roya 
Published: January 2021

Abstract
Background
COVID-19 caused some worries among pregnant women. Worries during pregnancy can affect women’s well-being. We investigated worry and well-being and associated factors among pregnant women during the COVID-19 pandemic.

Methods
This descriptive cross-sectional study was conducted on 484 pregnant women using an online questionnaire. Sampling was performed in a period between May 5 and Aug 5, 2020. Inclusion criteria were having a single healthy fetus and having no significant psychological disorder. We collected the data using the Persian versions of the World Health Organization’s Well-Being Index (WHO-5 Well-Being Index) and the Cambridge Worry Scale. We used univariate and multivariate logistic regression analyses to identify predictors of women’s worry and well-being.

Results
The mean total scores of the WHO-5 Well-Being Index and the percentage of WHO-5 score < 50 were 64.9 ± 29.0 and 24.4%, respectively. Predictors of women’s worry are the increased level of fear of COVID-19 (OR = 6.40, p <  0.001), a low family income (OR = 3.41, p <  0.001), employment status (OR = 1.86, p = 0.019), nulliparity (OR = 1.68, p = 0.024), having a COVID-19 infected person among relatives (OR = 2.45, p = 0.036), having a history of abortion (OR = 1.86, p = 0.012), having participated in the study after the first wave of COVID-19 outbreak (OR = 2.328, p = 0.003), and women’s age < 30 year (OR = 2.11, p = 0.002). Predictors of low level of well-being in pregnant women are worry about their own health and relationships (OR = 1.789, p = .017), worry about fetus health (OR = 1.946, p = 0.009), and having at least one infected person with COVID-19 among relatives (OR = 2.135, p = 0.036).

Conclusions
The percentage of women experiencing a low well-being state was relatively high. This result is worthy of attention by health care providers and policy makers. Providing care and support to pregnant women should have high priority during the COVID-19 pandemic.

Published: January 2021

Abstract
Background
Breast cancer is the second most common causes of women’s death, worldwide. Data on risk factors associated with female breast cancer in the Afghan population is very limited. The aim of our study was to identifying risk factor associated with female breast cancer in Afghanistan.

Methods
A retrospective case-control study was conducted with inclusion of 201 cases and 201 controls. Patient information was collected by interviewing the patient through a structured questionnaire. Histopathological information was collected from the hospital integrated laboratory management system. The data was analyzed by using logistic regression with univariate and multivariable analyses to determine the association between breast cancer and predictors.

Results
The results of the current study showed that factors such as: age (OR = 1.02; 95%CI: 0.99–1.04; p-0.148); age at menarche (OR = 0.83; 95%CI: 0.72–0.92; p-0.008); age at first baby (OR = 1.14; 95%CI: 1.07–1.20; p- < 0.001); illiteracy (OR = 1.93; 95%CI: 1.16–3.22; p-0.011); smoking (OR = 2.01; 95%CI: 1.01–3.99; p-0.04) and family history of cancer (OR = 1.98; 95%CI: 1.18–3.32; p-0.009) were significantly associated with breast cancer. However, our study did not demonstrate any statistically significant correlation between breast cancer and some of the predictors that were previously highlighted in literature, such as: marital status, Body Mass Index (BMI), use of hormonal contraceptive, breastfeeding and exercise.

Conclusion
Our study demonstrated that age at menarche, and age at first baby birth, illiteracy, smoking and family history of cancer were significant risk factors associated with development of breast cancer among women in Afghanistan. Health education of women regarding aforementioned predisposing factors are therefore, expected to be valuable in decreasing the burden of breast cancer with reduction of its burden on the healthcare system in Afghanistan.

Abstract
Background
Residential mobility during childhood increases risk of psychopathology in adulthood and is a common experience among Chinese children. This study investigated associations between number and age of first move, etiological risk factors for psychopathology, and common mental disorders in adolescence and early adulthood.

Methods
The sample included 39,531 undergraduates (84.5% completion rate) age 15–34 years in their first year at a Chinese comprehensive university in annual cross-sectional surveys during 2014–2018. Common mental disorders measured using standardised self-report instruments. Data analysed using logistic regression models and interaction analysis.

Results
Half of all students experienced one or more moves of residence before age 15 years. Outcomes of Depression, Somatisation, Obsessive-compulsive disorder, Hallucinations and Delusions, and Suicide attempts showed dose-response relationships with increasing number of moves. Other etiological risk factors, including childhood disadvantage and maltreatment, showed similar dose response relationships but did not confound associations with mobility. We found interactions between reporting any move and being a left-behind child on depression and somatisation; number of moves and younger age at first move on depression, somatisation, suicide attempts and hallucinations and delusions.

Conclusions
Residential mobility in childhood is associated with psychopathology in adulthood and this association increases with increasing number of moves. Mobility is also associated with childhood disadvantage and maltreatment but associations with psychopathology are independent of these factors. Multiplicative effects were shown for multiple moves starting at a younger age and if the participant had been a left-behind child.
