Network meta-analysis comparing the efficacy of biologic treatments for achieving complete resolution of nail psoriasis

Abstract Background Nail psoriasis (NP) is common and of high importance in patients with psoriasis. Complete resolution of NP at week 24‒26 is an unambiguous nail outcome accessible for indirect treatment comparison of biologics. Objective To evaluate the comparative efficacy of approved biologics in achieving complete resolution of NP at week 24‒26. Methods A network meta-analysis (NMA) was conducted to indirectly compare the efficacy of six biologics in achieving complete resolution of NP at week 24‒26 in patients with moderate-to-severe psoriasis and concomitant NP. Complete resolution of NP was defined as a score of zero on the Nail Psoriasis Severity Index (NAPSI), modified NAPSI (mNAPSI) or Physician’s Global Assessment of Fingernails (PGA-F). Results The probability of achieving complete resolution of NP was highest for ixekizumab (46.5%; 95% credibility interval [CrI] 35.1‒58.0; Surface Under the Cumulative RAnking curve [SUCRA] 97%), followed by brodalumab (37.0%; 17.0‒61.0; 79%), adalimumab (28.3%; 24.4‒32.4; 62%), guselkumab (27.7%; 21.1‒35.1; 58%), ustekinumab (20.8%; 10.2‒35.2; 37%), and infliximab (0.8%; 0.0‒8.9; 17%). Conclusion In patients with moderate-to-severe psoriasis and concomitant NP, ixekizumab has the greatest likelihood among approved biologics of achieving complete resolution of NP at week 24‒26. Findings should be interpreted carefully because of inherent study limitations.
Clinical outcomes of percutaneous debulking of tricuspid valve endocarditis in intravenous drug users

A retrospective case series of a percutaneous approach to debulk tricuspid valve endocarditis (TVE) using an 8 French mechanical aspiration system in patients with a history of intravenous drug use (IVDU) was reported. IVDU associated TVE is increasing in the United States and is associated with high mortality despite early surgical debridement. Patients with advanced disease, shock, and respiratory failure may not be candidates for surgical debridement or replacement. These patients have recurrent events despite medical therapy
Carbazole effect on ground- and excited-state properties of rhenium(I) carbonyl complexes with extended terpy-like ligands.

The ground- and excited-state properties of three novel complexes [ReCl(CO)3(Ln-κ2N)] bearing 2,2':6',2''-terpyridine, 2,6-di(thiazol-2-yl)pyridine and 2,6-di(pyrazin-2-yl)pyridine functionalized with 9-carbazole attached to the central pyridine ring of the triimine core via phenylene linkage were investigated by spectroscopic and electrochemical methods and were simulated using density functional theory (DFT) and time-dependent DFT. To get a deeper and broader understanding of structure-property relationships, the designed Re(i) carbonyl complexes were compared with previously reported analogous systems - without any groups attached to the phenyl ring and bearing pyrrolidine instead of 9-carbazole. The results indicated that attachment of the N-carbazolyl substituent to the triimine core has less influence on the nature of the triplet excited state of [ReCl(CO)3(Ln-κ2N)] than the pyrrolidine group. Additionally, the impact of the ligand structural modifications on the light emission of the Re(i) complexes under external voltage was preliminarily examined with electroluminescence spectra of diodes containing the synthesized new molecules in an active layer.
Frequency of Zygosity in Jak-2 Positive Patients with Polycythemia Vera-Pakistan’s Perspective

Background: Estimation of JAK2V617F mutational load in Polycythemia Vera (PV) helps to determine the severity of the disease phenotype, the risk of thrombotic events, progression to post-PV myelofibrosis and survival. Amplification Refractory Mutation Screening (ARMS) PCR or Allele Specific (AS) PCR is a simple easy method with a reasonable sensitivity for screening of zygosity.The purpose of this study was to see the frequency of disease burden and phenotypic characteristics in Pakistani patients diagnosed with JAK2V617F mutation positive PV. Materials and Methods: A cross-sectional study using non probability consecutive sampling was conducted at Hematology Department, Liaquat National Hospital Karachi from October 2018 to July 2019.Adult newly diagnosed JAK2V617F positive PV patients of either gender were included. Patients’ demographics, clinical characteristics and baseline CBC were noted. JAK2V617F zygosity was qualitatively analyzed by ARMS-PCR technique. Age and gender were stratified to see to see the result of qualitative and quantitative effect modifiers on these patients using Chi Square and fisher exact test as appropriate while mean comparison was done by independent t-test and one way ANOVAtest. P value of ≤0.05 was considered as significant. Results: Fifty one patients were included in the study with an average age of 59.60±14.29years. 90.2% of patients had hypertension.All patients tested positive for heterozygous state. Significant association of gender was found with smoking (p=0.001) while age was significantly linked with hypertension (p-0.033). Conclusion: JAK2V617F positive PV patients are mainly heterozygous males showing significant association with smoking and hypertension. ARMS-PCR is a robust technique to determine zygosity which can be used for screening purposes.
Knockout of Ajuba Attenuates the Growth and Migration of Hepatocellular Carcinoma Cells

Ajuba has been found to be mutated or aberrantly regulated in several human cancers and plays important roles in cancer progression via different signaling pathways. However, little is known about the role of Ajuba in hepatocellular carcinoma (HCC). Here, we found an upregulation of Ajuba expression in HCC tissues compared with normal liver tissues, while a poor prognosis was observed in HCC patients with high Ajuba expression. Knockout of Ajuba in HCC cells inhibited cell growth in vitro and in vivo, suppressed cell migration, and enhanced the cell apoptosis under stress. Moreover, re-expression of Ajuba in Ajuba-deficient cells could restore the phenotype of Ajuba-deficient cells. In conclusion, these results indicate that Ajuba is upregulated in HCC and promotes cell growth and migration of HCC cells, suggesting that Ajuba could possibly be a new target for HCC diagnosis and treatment.
Suicide prevention in childhood and adolescence: a narrative review of current knowledge on risk and protective factors and effectiveness of interventions

Suicide is a global mental health problem for people of all ages. While rates of suicide in children and adolescents are reported as lower than those in older populations worldwide, they represent the third leading cause of death in 15–19‐year‐olds. The rates are higher among boys than girls worldwide, though the death rates for girls exceed those for boys in Bangladesh, China, India, and Nepal. There has been a general decrease in adolescent suicide rates over recent decades. However, increases are reported in South East Asia as well as South America over the same time period.
Effectiveness of Allopurinol in Reducing Mortality: Time‐Related Biases in Observational Studies

The treatment of gout with allopurinol is effective at reducing urate levels and the frequency of flares. Several observational studies have shown important reductions in mortality with allopurinol use, with wide variations in results. We undertook this review to assess the extent of bias in these studies, particularly time‐related biases such as immortal time bias.
New anticancer Pd and Pt complexes of tertamyl dithiocarbamate and DACH ligands against HT29 and Panc1 cell lines

Abstract To investigate the reduction of side effects of commercial antitumor drugs such as cisplatin, two new platinum and palladium complexes with a formula of [M(DACH)(tertamyl.dtc)]NO3 were synthesized (DACH is 1R, 2R-diaminocyclohexane, tertamyl-dtc is tertpentyl dithiocarbamate, and M is palladium or platin ionic metals) and characterized by spectroscopic methods. The in vitro cytotoxicity of these compounds against HT29 and Panc1 cell lines showed that the IC50 values against Panc1 cell line of [Pt(DACH)(tertamyl.dtc)]NO3 and [Pd(DACH)(tertamyl.dtc)]NO3 were 263.1 and 198.7 µM, and also against HT29 cell line were 241.9 and 258.2 µM, respectively. They were similar to the value obtained for oxaliplatin and lower than cisplatin value. Thermal stability and circular dichroism results demonstrated that both metal complexes could bind to DNA via electrostatic bonds. Due to electrostatic interaction, the configuration of B-DNA to C-DNA changed, though the possibility of groove interaction may be strengthened. Furthermore, molecular docking simulation showed higher negative docking energy for [Pd(DACH)(tertamyl.dtc)]NO3 complex with a higher tendency for DNA interaction. In vitro cytotoxicity of two new Pt and Pd compounds have been studied against two cell lines (HT29 and Panc 1), which are almost equal to the value obtained for oxaliplatin and they are lower than cisplatin value. Thermal stability studies and CD results demonstrated that both complexes bind to DNA via electrostatic bonds. Further, molecular docking showed higher negative docking energy for [Pd(DACH)(tertamyl.dtc)]NO3 complex with a higher tendency for interaction. Communicated by Ramaswamy H. Sarma Graphical Abstract
Severity and 1-month outcome of SARS-CoV-2 infection in patients with solid cancers: a Danish nationwide cohort study

Abstract Background Cancer patients are vulnerable to infections, are older and often have comorbidities in comparison to the general population, which increases the risk for severe outcomes related to COVID-19 diagnosis. Methods This study is a prospective, nationwide study in patients with solid cancer and SARS-CoV-2 infection included between 10 March to 15 June 2020. Patient's baseline characteristics were collected. The study’s primary outcome was overall survival within 30 days of verified SARS-CoV-2 infection. Secondary outcomes were hospital admission, admission to an ICU, and need for supplemental oxygen. Results A total of 112 patients with a cancer diagnosis and verified SARS-CoV-2 infection were identified. After one month of follow up, hospitalization was required for 54% (n = 61) and 21% of the patients had died and 14 of the 23 deceased cancer patients were ≥70 years. Most patients were classified with mild COVID-19 symptoms (66%, n = 74); however, 48% (n = 23) of the ≥70-year-olds patients were classified with severe or critical COVID-19 symptoms. Among the total study population, 61% (n = 68) had comorbidities and comorbidity were more frequently observed among the deceased (91%, n = 21) and older cancer patients (≥70 years, 81%, n = 39). Conclusions Acknowledging the low sample size in this study, our work shows that age and comorbidities, but not recent cytotoxic therapy, are associated with adverse outcomes of SARS-CoV-2 infection for patients with solid cancer. Particularly, patients with progressive disease seem to be at greater risk of a fatal outcome from COVID-19. Highlights Age, performance status, and comorbidities are strong predictors of adverse outcome in cancer patients with SARS-CoV-2 infection. Patients with progressive cancer disease seem to be at greater risk of a fatal outcome from COVID-19. Recent cytotoxic therapy, however, did not seem to be associated with increased risk for adverse outcomes of SARS-CoV-2 infection for patients with solid cancer.
Effect of gamified perceptual learning on visual detection and discrimination skills in equine gait assessment.

BACKGROUND Visual assessment of equine lameness is an everyday veterinary task suffering from poor diagnostic accuracy. The aim of this study was to quantify the impact of the perceptual learning game 'LamenessTrainer' on skill development. METHODS Thirty-six undergraduate veterinary students engaged in four game modules teaching the assessment of fore- and hindlimb lameness. Computer animations of horses in this game displayed 0% (sound) to 70% (moderately lame) vertical movement asymmetry of head and pelvis. Performance, learning effects, diagnostic accuracy, detection thresholds and survey responses were analysed. RESULTS Following staircase learning, more than 80% of students reliably classified horses with ≥20% asymmetry for forelimb lameness, ≥40% asymmetry for simplified hindlimb lameness and ≥50% asymmetry for realistic hindlimb lameness. During random presentation, on average 82% of sound and 65% of lame horses were assessed correctly during forelimb lameness evaluation, dropping to 39% of sound and 56% of lame horses for hindlimb lameness. CONCLUSION In less than two hours, systematic perceptual learning through deliberate practice can develop visual assessment skills to an accuracy level comparable to expert assessors scoring the same animations. Skills should be developed further to improve misclassifications of sound and mildly lame horses, especially for hindlimb lameness evaluation.
Diacylphloroglucinol derivatives as antioxidant agents: green synthesis, optimisation, in vitro, and in silico evaluation

Abstract Several derivatives of diacylphloroglucinol (3a–3c and 5a–5b) as an analogue of natural product compound 2,4-diacetylphloroglucinol 3a, were successfully synthesised in an excellent yield via a greener Friedel–Craft acylation using methanesulfonic acid (MSA) as a catalyst under an ultrasound-assisted condition. Operational simplicity, excellent yield, expedient metal-free synthesis, energy-efficient and mild reaction conditions are the outstanding advantages in this procedure. A scaled-up reaction also revealed the practical suitability of this newly developed procedure. The effects of several process variables on 3a were carefully accomplished using response surface methodology (RSM). Moreover, the green credentials of the present protocol have been assessed using several established green metrics and compared to relevant procedures. Along with the monomers, dimeric diacylphloroglucinols (6a–6e) were also synthesised and their in vitro antioxidant activity of these species were carried out. Furthermore, drug-likeness, density functional theory (DFT), and molecular docking studies were also established. GRAPHICAL ABSTRACT
Physical activity and its association with cognitive function in middle- and older-aged Chinese: Evidence from China Health and Retirement Longitudinal Study, 2015

ABSTRACT Background Despite the known benefits of physical activity (PA) on cognitive function, the specific dimensions of PA that are associated with cognitive function require further research in China. We aimed to explore the patterns of PA and elucidate the association between cognitive function and different levels of PA in middle aged and elderly Chinese individuals. Methods A total of 8,023 participants aged ≥45 years were selected from the China Health and Retirement Longitudinal Study. The PA intensity was categorized as: vigorous (VPA), moderate (MPA), and light (LPA). The associations of frequency and duration of PA at different intensities with cognitive function were examined using the multivariable linear model, including all respondents and urban-rural subgroups. Results Compared with those who had no VPA, those who spent 6–7 days/week (β = −0.59, 95% CI: −1.10, −0.09) or more than 240 min/each time on VPA had poorer cognitive function among rural respondents, whereas cognitive function was only associated with the duration in urban respondents. Compared with those who had no MPA, the rural respondents who spent 1–5 days/week (β = 0.66, 95% CI: 0.12, 1.20) or 6–7days/week, or spent < 2 hours each time had better cognitive function. For LPA, frequency and duration were both positively associated with cognitive function, and were observed in both rural and urban sub-groups. Conclusions The association between cognitive function and PA depended largely on the intensity and area. Cultural context and geographical differences should be considered when designing intervention policies. Highlights The prevalence of PA increased as the intensity decreased and was higher in rural respondents than in urban respondents. Cognitive function was related to the intensity, frequency, and duration of PA. However, the magnitude and direction of the association depended mainly on the intensity and geographical area. VPA was negatively correlated with cognitive function, and the association was significant only in rural respondents. However, MPA and LPA were positively correlated with cognitive function, while the association between LPA and cognitive function was significant in both rural and urban respondents.
Sorting the File Drawer: A Typology for Describing Unpublished Studies

A typology of unpublished studies is presented to describe various types of unpublished studies and the reasons for their nonpublication. Reasons for nonpublication are classified by whether they stem from an awareness of the study results (result-dependent reasons) or not (result-independent reasons) and whether the reasons affect the publication decisions of individual researchers or reviewers/editors. I argue that result-independent reasons for nonpublication are less likely to introduce motivated reasoning into the publication decision process than are result-dependent reasons. I also argue that some reasons for nonpublication would produce beneficial as opposed to problematic publication bias. The typology of unpublished studies provides a descriptive scheme that can facilitate understanding of the population of study results across the field of psychology, within subdisciplines of psychology, or within specific psychology research domains. The typology also offers insight into different publication biases and research-dissemination practices and can guide individual researchers in organizing their own file drawers of unpublished studies.
Effects of intermittent pneumatic compression on femoral vein peak venous velocity during active ankle exercise

Introduction: The risk of developing deep vein thrombosis (DVT) is high even after the period of bed rest following major general surgery including total joint arthroplasty (TJA). Mobile intermittent pneumatic compression (IPC) devices allow the application of IPC during postoperative exercise. Although ambulation included ankle movement, no reports have been made regarding the effects of IPC during exercise, including active ankle exercise (AAE), on venous flow. This study was performed to examine whether using a mobile IPC device can effectively augment the AAE-induced increase in peak velocity (PV). Methods: PV was measured by Doppler ultrasonography in the superficial femoral vein at rest, during AAE alone, during IPC alone, and during AAE with IPC in 20 healthy subjects in the sitting position. PV in AAE with IPC was measured with a mobile IPC device during AAE in the strong compression phase. AAE was interrupted from the end of the strong compression phase to minimize lower limb fatigue. Results: AAE with IPC (76.2 cm/s [95%CI, 69.0–83.4]) resulted in a significant increase in PV compared to either AAE or IPC alone (47.1 cm/s [95%CI, 38.7–55.6], p < 0.001 and 48.1 cm/s [95%CI, 43.7–52.4], p < 0.001, respectively). Discussion: Reduced calf muscle pump activity due to the decline in ambulation ability reduced venous flow. Therefore, use of a mobile IPC device during postoperative rehabilitation in hospital and activity including self-training in an inpatient ward may promote venous flow compared to postoperative exercise without IPC. Conclusion: Use of a mobile IPC device significantly increased the PV during AAE, and simultaneous AAE with IPC could be useful evidence for the prevention of DVT in clinical settings, including after TJA.
Methylene blue enhances polyethylene glycol-fusion repair of completely severed rat sciatic nerves

Complete transection of peripheral mixed nerves immediately produces loss of sensory perception, muscle contractions and voluntary behavior mediated by the severed distal axons. In contrast to natural regeneration (~1 mm/d) of proximal axons that may eventually reinnervate denervated targets, re-innervation is restored within minutes by PEG-fusion that consists of neurorrhaphy and a sequence of well specified hypo- and isotonic calcium-free or calcium-containing solutions, the anti-oxidant methylene blue (MB) and the membrane fusogen polyethylene glycol (PEG). In this study, we examined the relative efficacy of PEG-fusion with no MB (0%), 0.5% MB, or 1% MB on the recovery of voluntary behaviors by female Sprague-Dawley rats with a complete mid-thigh severance of their sciatic nerve bathed in extracellular fluid or calcium-containing isotonic saline. The recovery of voluntary behaviors is the most relevant measure of success of any technique to repair peripheral nerve injuries. We assessed recovery by the sciatic functional index, a commonly used measure of voluntary hindlimb behaviors following complete sciatic transections. We reported that both 1% MB and 0.5% MB in sterile distilled water in our PEG-fusion protocol with neurorrhaphy significantly increased the rate and extent of behavioral recovery compared to PEG plus neurorrhaphy alone. Furthermore, 0.5% MB was as effective as 1% MB in voluntary behavioral recovery as assessed by the sciatic functional index. Since sterile 1% MB is no longer clinically available, we therefore recommend that 0.5% MB be included in upcoming human clinical trials to evaluate the safety and efficacy of PEG-fusion. All animal procedures were approved by the University of Texas Institutional Animal Care and Use Committee (AUP-2019-00225) on September 9, 2020.
Parathyroid hormone attenuates osteoarthritis pain by remodeling subchondral bone in mice

Osteoarthritis, a highly prevalent degenerative joint disorder, is characterized by joint pain and disability. Available treatments fail to modify osteoarthritis progression and decrease joint pain effectively. Here, we show that intermittent parathyroid hormone (iPTH) attenuates osteoarthritis pain by inhibiting subchondral sensory innervation, subchondral bone deterioration, and articular cartilage degeneration in a destabilized medial meniscus (DMM) mouse model. We found that subchondral sensory innervation for osteoarthritis pain was significantly decreased in PTH-treated DMM mice compared with vehicle-treated DMM mice. In parallel, deterioration of subchondral bone microarchitecture in DMM mice was attenuated by iPTH treatment. Increased level of prostaglandin E2 in subchondral bone of DMM mice was reduced by iPTH treatment. Furthermore, uncoupled subchondral bone remodeling caused by increased transforming growth factor β signaling was regulated by PTH-induced endocytosis of the PTH type 1 receptor–transforming growth factor β type 2 receptor complex. Notably, iPTH improved subchondral bone microarchitecture and decreased level of prostaglandin E2 and sensory innervation of subchondral bone in DMM mice by acting specifically through PTH type 1 receptor in Nestin+ mesenchymal stromal cells. Thus, iPTH could be a potential disease-modifying therapy for osteoarthritis.
