Well-designed evaluation involving co-expression cpa networks associated with zebrafish ace2 reveals enrichment associated with path ways associated with improvement along with disease.
Background Pediatric outcomes after flexor tendon repairs are variable, and evidence in the literature remains scarce. Methods Repair of pediatric flexor tendon injuries was reviewed over a 10-year period (2005-2015). Data collection consisted of patient demographics, injury characteristics, anesthetic choice, repair technique, rehabilitation protocol, American Society for Surgery of the Hand Total Active Motion (TAM) scores, and complications. Results There were 109 patients included in our study, with a total of 162 digits injured and 235 flexor tendon injuries. The mean age was 12 ± 4.6 years. The small finger (48 of 162; 30%) and the flexor digitorum profundus tendon (126 of 235) were the most commonly injured. The mechanism of injury was mainly from a knife (46 of 109; 42.2%) in zone II (82 of 159; 52%). Injuries were mostly repaired under general anesthetic (61 of 104; 56%). The Kessler technique was the predominant repair mechanism (111 of 225 repairs; 49%). Most patients (103 of 109; 95%) had excellent or good TAM scores with 5 postoperative ruptures reported. The most common complication was stiffness (17 of 121 complications; 14%), with most patients having no complications ( 74 of 109 patients; 68%). Patients were commonly immobilized (mean 8.4 ± 10.3 weeks) with a splint (93 of 109; 85%). There were 85 patients who followed a postoperative rehabilitation protocol for 12 ± 18 weeks. Patient demographics, time of repair, injury characteristics, anesthetic choice, and rehabilitation protocol were not significantly correlated with TAM scores or complication rates. Conclusions Pediatric tendon injuries have good outcomes with no predictive factors identified. Surgical repairs performed under local anesthetic have similar outcomes without increased rates of complications, but remain underused in the pediatric population.Background This study aimed to describe the epidemiology of pediatric upper extremity injury secondary to nonballistic firearms in the United States. Methods The National Electronic Injury Surveillance Survey (NEISS) database was queried between 2000 and 2017 for injuries to the upper extremity from nonballistic firearms in patients aged ≤18 years. In total, 1502 unique cases were identified. Using input parameters intrinsic to the NEISS database, national weighted estimates were derived using Stata/IC 15.1 statistical software (StataCorp LLC, College Station, Texas), which yielded an estimate of 52 118 cases of nonballistic firearm trauma to the upper extremity who presented to US emergency departments over the study period. Descriptive statistics were performed using NEISS parameters. Results An average of 2895 annual pediatric upper extremity nonballistic firearm injuries were identified between 2000 and 2017. Over 91% were sustained by men, and adolescents aged 12 to 18 were the most commonly injured (69.8%). Only 3.5% of all injuries required inpatient admission, and the most common sites of injury were the hand (41.1%), followed by fingers (35.9%). Conclusions We conclude that nonballistic firearm injuries represent a significant burden of disease to adolescent men in the United States.Introduction The aim of this study was to assess the relationship between polymorphisms of genes encoding enzymes involved in arsenic metabolism and urinary arsenic concentration in people occupationally exposed to arsenic. Materials and methods The data from 113 employers directly exposed to lead, cadmium, and arsenic in copper smelter in Legnica and Glogow were collected. Urinary arsenic concentration was measured. In addition, blood level of cadmium, lead, and zinc protoporphyrins was assayed. Genetic analyses included polymorphism of PNP (rs 1130650), GSTO-1 (rs 4925), AS3MT (rs 11191439), and ADRB3 (rs4994) genes. Results Individuals occupationally exposed to arsenic compounds, who have allele T in homozygous constellation in locus rs 1130650 of PNP gene, are predisposed to lower urinary arsenic concentration, while AA homozygosity in locus rs 4925 of GSTO-1 gene may result in statistically significant higher urinary arsenic concentration. Polymorphisms of AS3MT and ADRB3 genes showed no statistically significant correlation with urinary arsenic, however, there was a tendency to higher arsenic concentration in allele A carriers in locus rs4994 of ADRB3 gene and in allele T carriers in rs 11191439 of AS3MT gene. Conclusion This study indicates that arsenic absorption and metabolism depend on polymorphisms of genes encoding PNP and GSTO-1. Individuals with disadvantageous constellation of polymorphisms are more susceptible to harmful effects of arsenic exposure.Culturally specific beliefs about mental illnesses influence people's experience of mental illnesses and their likelihood of seeking help. This study explores how mothers in China understand the causes of postpartum depression (PPD) and their preferred coping strategies through semi-structured interviews. It finds that these mothers often take a situational approach to PPD, attributing it to external factors that could be changed (e.g., lack of support from in-laws) or to internal factors that will disappear over time (e.g., hormonal fluctuation). As a result, these mothers often choose to cope with their PPD symptoms through self-help strategies such as talking to someone, enlisting help, and positive thinking. Seeking professional help is not a preferred coping strategy. Furthermore, participants often make different attributions about the PPD experiences of themselves and the experiences of others. In explaining other women's PPD symptoms, they are more likely to evoke the myths about gender and motherhood in the Chinese culture and blame PPD on these mothers' personality flaws, husbands' affairs, and financial hardships. Practically, our findings provide baseline data for the promotion of professional mental health care among mothers experiencing PPD in China.Purpose To evaluate the morphological, clinical, and tomographic characteristics of focal choroidal excavation in the context of concomitant retinal pathologies. Methods This case series included 13 eyes of 13 patients with focal choroidal excavation diagnosed by spectral-domain optical coherence tomography. Morphologic characteristics of excavation and quantitative thicknesses of retinal layers and choroid were analyzed in excavation area, area adjacent to excavation, and fellow eye without focal choroidal excavation by spectral-domain optical coherence tomography. Results At the initial examinations, one eye had a history of blunt trauma, three eyes were diagnosed with choroidal neovascularization, one with choroidal osteoma, one with angioid streaks, one with retinal detachment, one with diabetic macular edema, one with optic pit, one with torpedo maculopathy, and the rest three with idiopathic focal choroidal excavation. SC75741 The mean choroidal thickness in the area of focal choroidal excavation was statistically significantly thinner compared to in the area adjacent to focal choroidal excavation and fellow eye (p less then 0.001) and total average outer nuclear layer thickness was statistically significantly thicker in the area of excavation compared with fellow eye (p = 0.007). Conclusion This study confirmed the presence of focal choroidal excavation in various ocular diseases and the evaluation of focal choroidal excavation using the spectral-domain optical coherence tomography demonstrated choroidal thinning and outer nuclear layer thickening in the area of the excavation.Introduction A significant proportion of patients with advanced primary or metastatic intrathoracic malignancy will eventually develop central airway obstruction. The morbidity associated with malignant airway obstruction (MAO) is considerable and the management is difficult. Our aim was to evaluate the outcomes of tracheobronchial stenting in patients with MAO and its role in palliative care. Material and methods This retrospective study involved a consecutive case series of patients with advanced cancer with MAO who underwent tracheobronchial stenting between August 2014 and August 2019. The European Cooperative Oncology Group (ECOG) scale was used to evaluate patient functional status before and after tracheobronchial stenting. Univariate survival analysis included Kaplan-Meier curves with Log-Rank test, while Cox regression was used as a multivariate analysis. Results We included 28 patients with median age of 55.0 years (interquartile range = 49.3-66.5) and 89.3% male. The most frequent primary tumour was the esophagus followed by lungs. The majority of the patients (75%) expressed immediate symptom relief after stenting and there was a significant improvement in the mean ECOG performance status (PS; P = .005). There was no intraprocedure mortality and complications were observed in 6 patients. The median survival after airway stenting was 39.0 days (95% CI = 32.2-45.8) with poorer PS after stent insertion associated with lower overall survival (hazard ratio = 2.3 [95% CI = 1.1-4.9], P = .030) on multivariate analysis. Conclusion Airway stent is a safe and effective procedure that offers rapid palliation of symptoms with no major complications. Therefore, stent placement should be considered as part of the treatment of patients with terminal cancer.Mesenchymal stem cells (MSCs) are thought to have great potential in the therapy of acute liver injury. It is possible that these cells may be regulated by the stromal cell-derived factor-1 (SDF-1)/CXC chemokine receptor-4 (CXCR4) signaling axis, which has been shown to promote stem cells migration in the inflammation-associated diseases. However, the effects of SDF-1/CXCR4 axis on the MSCs-transplantation-based treatment for acute liver injury and the underlying mechanisms are largely unknown. In this study, we sought to determine whether SDF-1/CXCR4 would augment the therapeutic effect of bone marrow mesenchymal stem cells (BMSCs) by promoting their migration, which may result from activating the phosphoinositide 3-kinase (PI3K)/Akt signaling pathway, in a rat acute liver injury model induced by lipopolysaccharide (LPS). We found that BMSCs transplantation markedly attenuated liver injury and improved the survival of LPS-treated rats. Of interest, overexpression of CXCR4 in BMSCs could substantially promote their migration both in vitro and in vivo, and result in even better therapeutic effects. This might be attributed to the activation of PI3K/Akt signaling pathway in BMSCs that is downstream of CXCR4, as demonstrated by the use of the CXCR4 antagonist AMD3100 and PI3K pathway inhibitor LY294002 assays in vitro and in vivo. Together, our results unraveled a novel molecular mechanism for the therapeutic effect of BMSCs for the treatment of acute liver injury, which may shed a new light on the clinical application of BMSCs for acute liver failure.Head and neck squamous cell carcinoma (HNSCC) is a malignant tumor of the upper aerodigestive tract affecting the oral cavity, lips, paranasal sinuses, larynx, and nasopharynx. Proteogenomics combines proteomics and genomics and employs mass spectrometry and high-throughput sequencing technologies to identify novel peptides. The aim of this study was to identify potential protein biomarkers for clinical treatment of HNSCC. To achieve this, we utilized two sets of data, one on proteins from The Cancer Proteome Atlas (TCPA) and the other on gene expression from The Cancer Genome Atlas (TCGA) database, to evaluate dysfunctional proteogenomics microenvironment. Univariate Cox regression analysis was performed to examine the relationship between protein signatures and prognosis. A total of 19 proteins were significantly associated with overall survival (OS) of patients, of which E2F transcription factor 1 (E2F1; HR = 4.557, 95% CI = 1.810 to 11.469) and enhancer of zeste homolog 2 (EZH2; HR = 0.430, 95% CI = 0.187 to 0.
