Published: March 2021

ObjectiveDistinguishing benign from malignant adult neck masses can be challenging because data to guide risk assessment are lacking. We examined patients with neck masses from an integrated health system to identify patient and mass factors associated with malignancy.Study DesignRetrospective cohort.SettingKaiser Permanente Northern California.MethodsThe medical records of adults referred to otolaryngology in 2017 for a neck mass were evaluated. Bivariate and multivariable logistic regression analyses were performed.ResultsMalignancy was found in 205 (5.0%) of the cohort’s 4103 patients. Patient factors associated with malignancy included sex, age, and race/ethnicity. Males had more than twice the odds of malignancy compared with females (adjusted odds ratio [aOR] = 2.38). Malignancy rates increased with age, ranging from 2.1% for patients younger than 40 years to 8.4% for patients 70 years or older. White non‐Hispanic patients had 1.75 times the risk of malignancy compared with patients of other race/ethnicities. The percentage of patients with malignancy increased with increasing minimum mass dimension, from 3.0% in patients with mass size <1 cm to over 31% in patients with mass sizes 2 cm or larger (P <. 0001). Imaging‐based mass factors most highly predictive of malignancy included larger minimum mass dimension (≥1.5 cm vs <1.5 cm: aOR = 3.87), multiple masses (2 or more vs 1: aOR = 5.07), and heterogeneous/ill‐defined quality (aOR = 2.57).ConclusionMost neck masses referred to otolaryngology were not malignant. Increasing age, male sex, white non‐Hispanic ethnicity, increasing minimum mass dimension, multiple neck masses, or heterogeneous architecture/ill‐defined borders were associated with malignancy.

Authors: Mittal Niti , Mittal Rakesh , Gupta M. C. 
Published: March 2021

Background: Being a nonbenzodiazepine, zolpidem is believed to have a favorable side-effect profile and is widely prescribed for insomnia. However, in the past few years, numerous neuropsychiatric adverse reactions, particularly complex sleep behaviors (CSBs), have been reported with zolpidem. Objective: To conduct a systematic review of zolpidem-associated CSBs. Data Sources: An electronic search was conducted using MEDLINE, Embase, PubMed, and Cochrane database of systematic reviews to extract relevant articles till July 2020. Study Eligibility Criteria: Any type of literature article (case report, case series, and observational or interventional study) reporting CSBs associated with zolpidem. Results: In this review, we present aggregate summarized data from 148 patients presenting with zolpidem-induced CSBs (79 patients from 23 case reports and 5 case series; 69 patients out of 1454 taking zolpidem [4.7%] from three observational clinical studies). Various types of CSBs associated with zolpidem were reported, most common being sleepwalking/somnambulism and sleep-related eating disorder. On causality assessment, around 88% of cases were found to have a probable association with zolpidem. Limitations: Extraction of data from observational studies and spontaneous reports, due to nonavailability of any randomized controlled trials relevant to the study objective. Conclusion and Implication of Key Findings: Zolpidem-induced CSBs, although not very common, may develop when the drug is used at therapeutic doses for insomnia. Doctors need to be alert to monitor such adverse effects of zolpidem and exercise caution while prescribing it.

Published: March 2021

Background: Mortality attributable to coronavirus disease-19 (COVID-19) 2 infection occurs mainly through the development of viral pneumonia-induced acute respiratory distress syndrome (ARDS). Research Question: The objective of the study is to delineate the clinical profile, predictors of disease progression, and 30-day mortality from ARDS using the Veterans Affairs Corporate Data Warehouse. Study Design and Methods: Analysis of a historical cohort of 7,816 hospitalized patients with confirmed COVID-19 infection between January 1, 2020, and August 1, 2020. Main outcomes were progression to ARDS and 30-day mortality from ARDS, respectively. Results: The cohort was comprised predominantly of men (94.5%) with a median age of 69 years (interquartile range [IQR] 60-74 years). 2,184 (28%) were admitted to the intensive care unit and 643 (29.4%) were diagnosed with ARDS. The median Charlson Index was 3 (IQR 1-5). Independent predictors of progression to ARDS were body mass index (BMI) ≥40 kg/m2, diabetes, lymphocyte counts <700 × 109/L, LDH >450 U/L, ferritin >862 ng/ml, C-reactive protein >11 mg/dL, and D-dimer >1.5 ug/ml. In contrast, the use of an anticoagulant lowered the risk of developing ARDS (OR 0.66 [95% CI 0.49-0.89]. Crude 30-day mortality rate from ARDS was 41% (95% CI 38%-45%). Risk of death from ARDS was significantly higher in those who developed acute renal failure and septic shock. Use of an anticoagulant was associated with 2-fold reduction in mortality. Survival benefit was observed in patients who received corticosteroids and/or remdesivir but there was no advantage of combination therapy over either agent alone. Conclusions: Among those hospitalized for COVID-19, nearly 1 in 10 progressed to ARDS. Septic shock, and acute renal failure are the leading causes of death in these patients. Treatment with either remdesivir and corticosteroids reduced the risk of mortality from ARDS. All hospitalized patients with COVID-19 should be placed at a minimum on prophylactic doses of anticoagulation.

Background and Objective: The causal role of maternal nutrition in orofacial clefts is uncertain. We tested hypotheses that low maternal vitamin B12 and low folate status are each associated with an increased risk of isolated cleft lip with or without cleft palate (CL±P) in a case–control study in Tamil Nadu state, India. Methods: Case-mothers of CL±P children (n = 47) and control-mothers of unaffected children (n = 50) were recruited an average of 1.4 years after birth of the index child and plasma vitamin B12, methylmalonic acid (MMA), total homocysteine (tHcy), and folate were measured at that time. Logistic regression analyses estimated associations between nutrient biomarkers and case–control status. Results: Odds ratios (ORs) contrasting biomarker levels showed associations between case-mothers and low versus high plasma vitamin B12 (OR = 2.48, 95% CI, 1.02-6.01) and high versus low plasma MMA, an indicator of poor B12 status (OR = 3.65 95% CI, 1.21-11.05). Case–control status was not consistently associated with folate or tHcy levels. Low vitamin B12 status, when defined by a combination of both plasma vitamin B12 and MMA levels, had an even stronger association with case-mothers (OR = 6.54, 95% CI, 1.33-32.09). Conclusions: Mothers of CL±P children in southern India were 6.5 times more likely to have poor vitamin B12 status, defined by multiple biomarkers, compared to control-mothers. Further studies in populations with diverse nutritional backgrounds are required to determine whether poor maternal vitamin B12 or folate levels or their interactions are causally related to CL±P.

Background: This retrospective study evaluates the clinical outcomes of two heparin-bonded expanded polytetrafluoroethylene grafts, PROPATEN and ACUSEAL (W. L. Gore & Associates, Flagstaff, AZ, USA), for forearm loop vascular access. Methods: We prospectively collected data on 60 patients who had undergone arteriovenous graft of the forearm loop type between January 2015 and December 2019. The primary endpoints were graft primary, assisted primary, and secondary patency rates. Secondary endpoints were time to first cannulation and postoperative complications. Results: We enrolled 36 patients in the PROPATEN group (Group P) and 24 in the ACUSEAL group (Group A). All procedures were successful without any 30-day mortality. The median times to first cannulation were 16.5 days and 3 days in Groups P and A, respectively ( p < 0.001). Mean follow-up periods were 13.4 ± 14.5 and 17.3 ± 9.3 months, respectively. Primary patency rates were 81% and 64%, respectively, at 6 months, and 60% and 40%, respectively, at 12 months ( p = 0.008). Assisted primary patency rates were 96% and 83% at 6 months, 91% and 73% at 12 months, and 81% and 35% at 24 months ( p = 0.044). Secondary patency rates were 96% and 81% at 12 months, and 87% and 62% at 24 months ( p = 0.207). As a remote-period complication, disruption of the luminal layer of the graft was observed in two patients (4.2%) in Group A due to puncture and thrombectomy. Conclusions: Although the ACUSEAL graft offers the advantage of early cannulation, its primary and assisted primary patency outcomes were inferior to those of the PROPATEN graft. It is important for physicians to be aware of the different characteristics of each graft to select the best option for each patient.

Published: March 2021

Background We are trying to evaluate silver nanoparticles’ effectiveness (SilvrSTAT Gel) in accelerating healing rate of nonischemic diabetic foot ulcers (DFUs). Methods This prospective, double-blind, randomized, controlled study includes 80 patients with nonischemic DFUs classified into 2 groups. Group A was subjected to SilvrSTAT Gel dressing, and group B was subjected to conventional dressing (wet-to-moist dressing with or without povidone-iodine). All cases had minimal debridement before treatment. In both groups, all cases were nonischemic after successful revascularization either by bypass surgery or endovascular therapy. Results The healing rate of the SilvrSTAT group was significantly higher than that of the conventional group. The healing rate per week of the SilvrSTAT group was considerably higher than that of the conventional group ( P < .0001). The rate of complete healing for ulcers in group A was achieved in 22 patients (55%) by the 6th week, while 29 (72.5%), 34 (85%), and 36 (90%) patients were healed entirely by the 8th, 10th, and 12th weeks, respectively. In group B: 20 (50%), 27 (67.5%), and 30 (75%) patients were completeley healed by the 8th, 10th, and 12th weeks, respectively. Conclusions SilvrSTATGel is effective in the treatment of DFU.

Background Human twin studies and other studies have indicated that chronic pain has heritability that ranges from 30% to 70%. We aimed to identify potential genetic variants that contribute to the susceptibility to chronic pain and efficacy of administered drugs. We conducted genome-wide association studies (GWASs) using whole-genome genotyping arrays with more than 700,000 markers in 191 chronic pain patients and a subgroup of 89 patients with postherpetic neuralgia (PHN) in addition to 282 healthy control subjects in several genetic models, followed by additional gene-based and gene-set analyses of the same phenotypes. We also performed a GWAS for the efficacy of drugs for the treatment of pain. Results Although none of the single-nucleotide polymorphisms (SNPs) were found to be genome-wide significantly associated with chronic pain ( p ≥ 1.858 × 10−7), the GWAS of PHN patients revealed that the rs4773840 SNP within the ABCC4 gene region was significantly associated with PHN in the trend model (nominal p = 1.638 × 10−7). In the additional gene-based analysis, one gene, PRKCQ, was significantly associated with chronic pain in the trend model (adjusted p = 0.03722). In the gene-set analysis, several gene sets were significantly associated with chronic pain and PHN. No SNPs were significantly associated with the efficacy of any of types of drugs in any of the genetic models. Conclusions These results suggest that the PRKCQ gene and rs4773840 SNP within the ABCC4 gene region may be related to the susceptibility to chronic pain conditions and PHN, respectively.

Abstract
Mutations in the transcription factors GATA binding factor 1 (GATA1), growth factor independence 1B (GFI1B), and Runt-related transcription factor 1 (RUNX1) cause familial platelet and bleeding disorders. Mutant platelets exhibit common abnormalities including an α-granule reduction resulting in a grayish appearance in blood smears. This suggests that similar pathways are deregulated by different transcription factor mutations. To identify common factors, full platelet proteomes from 11 individuals with mutant GATA1R216Q, GFI1BQ287*, RUNX1Q154Rfs, or RUNX1TD2-6 and 28 healthy controls were examined by label-free quantitative mass spectrometry. In total, 2875 platelet proteins were reliably quantified. Clustering analysis of more than 300 differentially expressed proteins revealed profound differences between cases and controls. Among cases, 44 of 143 significantly downregulated proteins were assigned to platelet function, hemostasis, and granule biology, in line with platelet dysfunction and bleedings. Remarkably, none of these proteins were significantly diminished in all affected cases. Similarly, no proteins were commonly overrepresented in all affected cases compared with controls. These data indicate that the studied transcription factor mutations alter platelet proteomes in distinct largely nonoverlapping manners. This work provides the quantitative landscape of proteins that affect platelet function when deregulated by mutated transcription factors in inherited bleeding disorders.
Genome-wide analysis of spatiotemporal expression patterns during rice leaf development
Authors: Miya Masayuki , Yoshikawa Takanori , Sato Yutaka , Itoh Jun-Ichi 
Published: March 2021

Abstract
Background
Rice leaves consist of three distinct regions along a proximal-distal axis, namely the leaf blade, sheath, and blade-sheath boundary region. Each region has a unique morphology and function, but the genetic programs underlying the development of each region are poorly understood. To fully elucidate rice leaf development and discover genes with unique functions in rice and grasses, it is crucial to explore genome-wide transcriptional profiles during the development of the three regions.

Results
In this study, we performed microarray analysis to profile the spatial and temporal patterns of gene expression in the rice leaf using dissected parts of leaves sampled in broad developmental stages. The dynamics in each region revealed that the transcriptomes changed dramatically throughout the progress of tissue differentiation, and those of the leaf blade and sheath differed greatly at the mature stage. Cluster analysis of expression patterns among leaf parts revealed groups of genes that may be involved in specific biological processes related to rice leaf development. Moreover, we found novel genes potentially involved in rice leaf development using a combination of transcriptome data and in situ hybridization, and analyzed their spatial expression patterns at high resolution. We successfully identified multiple genes that exhibit localized expression in tissues characteristic of rice or grass leaves.

Conclusions
Although the genetic mechanisms of leaf development have been elucidated in several eudicots, direct application of that information to rice and grasses is not appropriate due to the morphological and developmental differences between them. Our analysis provides not only insights into the development of rice leaves but also expression profiles that serve as a valuable resource for gene discovery. The genes and gene clusters identified in this study may facilitate future research on the unique developmental mechanisms of rice leaves.

AbstractBackgroundTartary buckwheat seed development is an extremely complex process involving many gene regulatory pathways. MicroRNAs (miRNAs) have been identified as the important negative regulators of gene expression and performed crucial regulatory roles in various plant biological processes. However, whether miRNAs participate in Tartary buckwheat seed development remains unexplored.ResultsIn this study, we first identified 26 miRNA biosynthesis genes in the Tartary buckwheat genome and described their phylogeny and expression profiling. Then we performed small RNA (sRNA) sequencing for Tartary buckwheat seeds at three developmental stages to identify the miRNAs associated with seed development. In total, 230 miRNAs, including 101 conserved and 129 novel miRNAs, were first identified in Tartary buckwheat, and 3268 target genes were successfully predicted. Among these miRNAs, 76 exhibited differential expression during seed development, and 1534 target genes which correspond to 74 differentially expressed miRNAs (DEMs) were identified. Based on integrated analysis of DEMs and their targets expression, 65 miRNA-mRNA interaction pairs (25 DEMs corresponding to 65 target genes) were identified that exhibited significantly opposite expression during Tartary buckwheat seed development, and 6 of the miRNA-mRNA pairs were further verified by quantitative real-time polymerase chain reaction (qRT-PCR) and ligase-mediated rapid amplification of 5′ cDNA ends (5′-RLM-RACE). Functional annotation of the 65 target mRNAs showed that 56 miRNA-mRNA interaction pairs major involved in cell differentiation and proliferation, cell elongation, hormones response, organogenesis, embryo and endosperm development, seed size, mineral elements transport, and flavonoid biosynthesis, which indicated that they are the key miRNA-mRNA pairs for Tartary buckwheat seed development.ConclusionsOur findings provided insights for the first time into miRNA-mediated regulatory pathways in Tartary buckwheat seed development and suggested that miRNAs play important role in Tartary buckwheat seed development. These findings will be help to study the roles and regulatory mechanism of miRNAs in Tartary buckwheat seed development.

Published: March 2021

Abstract
Background
The literature on workplace interventions focusing on recovery is scarce; hence this study intends to expand that knowledge. An intervention was run for one year, aiming at increasing the experience of recovery during the workday among primary health care employees. During the intervention, different forms of recovery activities were integrated into the daily work at six primary health care centres. The aim of this study was to explore the intervention process and its effects.

Methods
After completion of an intervention, 39 employees in seven focus groups were interviewed about their experiences of the intervention. A semi-structured interview guide was used, and the qualitative analysis was conducted by systematic text condensation.

Results
Despite different conditions and attitudes when the project was launched, the participants portrayed a positive outcome of the intervention at all six workplaces. Four promoting factors for intervention success were identified: support, legitimacy, customization, and simplicity. Also, three areas of improvement during the intervention period were described: the workplace climate, employee well-being, and recovery awareness, which in turn became promoting factors.

Conclusions
An intervention aiming at increasing workplace recovery can be promoted by support, legitimacy, customization, and simplicity. By using these promoting factors, health care workplaces can implement activity models which could increase employees’ experiences of recovery during the workday. Positive effects on workplace climate and employee well-being can also be achieved.
Does self-reported symptom questionnaire play a role in nonadherence to colonoscopy for risk-increased population in the Tianjin colorectal cancer screening programme?

Published: March 2021

Abstract
Background
A colorectal cancer screening programme (CCSP) was implemented from 2012 to 2017 in Tianjin, China. Residents with a positive faecal immunochemical test (FIT) or positive self-reported symptom questionnaire (SRSQ) were recommended to undergo colonoscopy. The objective was to investigate the potential factors associated with nonadherence to colonoscopy among a risk-increased population.

Methods
Data were obtained from the CCSP database, and 199,522 residents with positive FIT or positive SRSQ during two screening rounds (2012–2017) were included in the analysis. Logistic regression analysis was performed to assess the association between nonadherence to colonoscopy and potential predictors.

Results
A total of 152,870 (76.6%) individuals did not undergo colonoscopy after positive FIT or positive SRSQ. Residents with positive SRSQ but without positive FIT were more likely not to undergo colonoscopy (negative FIT: OR, 2.35; 95% CI, 2.29–2.41, no FIT: OR, 1.27; 95% CI, 1.24–1.31). Patients without a cancer history were less likely to undergo colonoscopy even if they received risk-increased reports based on the SRSQ.

Conclusion
In the CCSP, seventy-seven percent of the risk-increased population did not undergo colonoscopy. FIT should be recommended since positive FIT results are related to improved adherence to colonoscopy. Residents with negative FIT but positive SRSQ should be informed of the potential cancer risk to ensure adherence to colonoscopy.
