RESUMEN

Singlet fission (SF) is a promising approach in quantum information science because it can generate spin-entangled quintet triplet pairs by photoexcitation independent of temperature. However, it is still challenging to rationally achieve quantum coherence at room temperature, which requires precise control of the orientation and dynamics of triplet pairs. Here we show that the quantum coherence of quintet multiexcitons can be achieved at room temperature by arranging two pentacene chromophores in parallel and in close proximity within a macrocycle. By making dynamic covalent Schiff-base bonds between aldehyde-modified pentacene derivatives, macrocyclic parallel dimer-1 (MPD-1) can be selectively synthesized in a high yield. MPD-1 exhibits fast subpicosecond SF in polystyrene film and generates spin-polarized quintet multiexcitons. Furthermore, the coherence time T2 of the MPD-1 quintet is as long as 648 ns, even at room temperature. This macrocyclic parallel dimer strategy opens up new possibilities for future quantum applications using molecular multilevel qubits.

RESUMEN

Background: The involvement of Wnt-1-induced secreted protein-1 (WISP1/CCN4) in several inflammatory reaction has recently been proposed. Nevertheless, this protein's involvement in rheumatoid arthritis (RA) remains debated. Associations between poorly diagnosed RA and several classical markers derived from demography and biochemistry have been reported. Aim: We sought to investigate the reliability and effectiveness of serum concentrations of CCN4, vascular cell adhesion molecule-1 (VCAM-1), matrix melloprotenase-3 (MMP-3), and granulocyte-macrophage colony-stimulating factor (GM-CSF) in monitoring and predicting RA and bone damage, and their correlation with RA disease course. Methods: The study analyzed 128 patients with RA, comprising 68 newly diagnosed and 60 previously diagnosed patients, as well as 60 controls. Biomarker levels were measured with enzyme linked immuno-sorbent assays. Routine laboratory parameters such as serological, clinical, biochemical, and hematological parameters were additionally measured. Demography, anthropometry, and clinical symptom data were collected through interviews and a questionnaire. The joint disease activity score 28 (DAS28) was used to determine disease activity. Results: Concentrations of four biomarkers were significantly higher in the RA group than the healthy controls. Elevated biomarker concentrations were also observed in patients with high, rather than moderate or low, DAS28-ESR activity status, except for monocyte count, hematocrit (%), and urea level. Furthermore, CCN4 level positively correlated with VCAM-1, MMP-3, and GM-CSF levels, DA-S28-CRP and DAS28-ESR. The levels of three predictive markers, CCN4, VCAM-1, and MMP-3, were elevated in non-treated patients, whereas GM-CSF level showed no difference. The highest area under the curve was 73.3% for CCN4, with 93.3% sensitivity and 64.7% specificity. Conclusion: Our data suggest that CCN4 can be reliably used to indicate activity and therapeutic response associated with RA, thus facilitating earlier RA diagnosis.

RESUMEN

Ovarian cancer is the second most common and lethal gynecologic malignancy. Among natural product-based therapy, the honeybee products, particularly propolis, serve a valuable source contributing directly to human nutrition and health.In the present study, we determined the chemical composition of different types of propolis originating from Egypt, Germany and France using liquid chromatography-tandem mass spectrometry. The compounds identified belong to different metabolite classes, including flavonoids, cinnamic acid, chalcones, terpenoids, phenolic lipids, stilbenes, phenolic compounds, carbohydrates, vitamins, coumarins, polyprenylated benzophenone, benzoic acids, fatty acid methyl ester, and coumaric acid, and their derivatives. The most active extract is from France then Egypt and Germany.Afterwards, we treated the human ovarian cancer cells, OVCAR4, with different concentrations (1-400 µg/mL) of variable propolis types supplemented or not with vitamin D (0.0015-0.15 µg/mL) in order to evaluate the efficacy and the cytotoxic activities of our local P as compared to other types collected from different geographic regions. Importantly, the combinatorial treatment of OVCAR4 cancer cells with propolis and vitamin D in the same concentration ranges resulted in enhanced cell viability inhibition. Furthermore, such co-supplementation with vitamin D inhibits predominately the proliferative activity of cell population with the French propolis type as manifested by Ki67 expression, while it reduces considerably its expression, particularly with the German type, followed by the Egyptian one.Nowadays, scientists are interested by natural products which have risen to the forefront of drug discovery. Chemically characterized propolis showing cell viability inhibition and antiproliferative potential seems a valuable extract for further consideration as anti-carcinogenic agent.

RESUMEN

Background: Valvular heart disease (VHD) represents a spectrum of cardiac conditions, including valvular stenosis, valvular regurgitation, or mixed lesions affecting single or multiple valves. The severity of VHD has emerged as a major cause of cardiovascular (CV) morbidity and mortality among the older population in the United States (U.S). Objective: To evaluate temporal trends in mortality associated with VHD in the elderly U.S population between 1999 and 2019. Methods: We utilized the CDC WONDER database for VHD mortality in adults ≥75 from 1999 to 2019, using ICD-10 codes. Age-adjusted mortality rates (AAMR) per 100,000 people with associated annual percentage change (APC) were calculated. Joinpoint regression was used to assess the overall trends and trends for demographic, geographic, and type of valvular disease subgroups. Results: A total of 666,765 VHD deaths in older adults from 1999 to 2019 was identified, with an initial decline in AAMR until 2007 with an APC: 0.62, 95 % CI (-1.66-0.33), stability until 2014, and a significant decrease until 2019 (APC: 1.47, 95 % CI [-2.24-1.04], P < 0.0001). Men consistently had higher AAMRs compared to women (overall AAMR men: 173.6; women: 138.2). The AAMRs were found to be highest in the White (166.5), followed by American Indian or Alaska Native population at (93.8) Hispanic or Latino at (80.7), Black or African American populations at (74.1) and lastly Asian or Pacific Islander (73.4). Non-metropolitan areas manifested higher AAMRs for deaths related to VHD than metropolitan areas (overall AAMRs 160.5 vs 149.5) respectively. State-wide AAMRs varied, with the highest in Vermont at 324.2 (95 % CI [313.0-335.4], P < 0.0001) and the lowest in Mississippi at 88.0 (95 % CI [85.0-91.0], P < 0.0001). Non-rheumatic and aortic valve disorders in adults ≥75 years had higher mortality rates compared to rheumatic or mitral valve conditions in those <75 years. Conclusion: Our study showed a decline in U.S. VHD mortality from 1999 to 2019 but found persistent disparities by gender, race, age, region, and VHD type. Targeted policies for prevention and early diagnosis are needed to address these inequalities.

RESUMEN

INTRODUCTION: An unusual association between thyroid dysfunction and autoimmune encephalitis (AE) was noticed when patients presented with low free triiodothyronine (fT3) levels and antithyroid antibodies. We conducted a meta-analysis to investigate whether thyroid dysfunction, that is, lower fT3 levels are associated with worsening clinical manifestations and prognosis in patients with AE. METHODS: Literature search of five electronic databases was performed till April 5, 2023. Inclusion criteria were as follows: Observational studies reporting patients with all subtypes of AE and assessing thyroid dysfunction categorized as low fT3 and non-low fT3. Primary endpoints included modified Rankin scale (mRS) at admission, abnormal magnetic resonance imaging, length of stay, seizures, and consciousness declination. RESULTS: Comprehensive literature search resulted in 5127 studies. After duplicate removal and full-text screening, six observational studies were included in this analysis. Patients with low fT3 were 2.95 times more likely to experience consciousness declination (p = .0003), had higher mRS at admission (p < .00001), had 3.14 times increased chances of having a tumor (p = .003), were 3.88 times more likely to experience central hypoventilation, and were 2.36 times more likely to have positivity for antithyroid antibodies (p = .009) as compared to patients with non-low fT3. CONCLUSION: The findings of our study suggest that low fT3 levels might be related to a more severe disease state, implying the significance of thyroid hormones in AE pathogenesis. This finding is crucial in not only improving the early diagnosis of severe AE but also in the efficient management of the disease.

RESUMEN

Two chitosan Schiff bases were synthesized by condensation of chitosan with 2-(4-formylphenoxy)-N-phenylacetamide and N-(4-bromophenyl)-2-(4-formylphenoxy) acetamide denoted as Cs-SBA and Cs-SBBr, respectively. The molecular structures of the resulting chitosan derivatives were characterized using FTIR and 1HNMR and their thermal properties were investigated by TGA. These derivatives were treated with sodium tripolyphosphate (TPP) to produce Cs Schiff base nanoparticles. The nanoparticles physicochemical properties were determined by FTIR, XRD, TEM, and zeta potential analysis. The antimicrobial action against Helicobacter pylori (H. pylori) was evaluated and the results indicated that the anti-H. pylori activity had minimal inhibitory concentration MIC values of 15.62 ± 0.05 and 3.9 ± 0.03 µg/mL for Cs-SBA and Cs-SBBr nanoparticles (Cs-SBA NPs and Cs-SBBr NPs), respectively. The better biologically active nanoparticles, Cs-SBBr NPs, were tested for their cyclooxygenases (COX-1 and COX-2) inhibitory potential. Cs-SBBr NPs demonstrated COX enzyme inhibition activity against COX-2 (IC50 4.5 ± 0.165 µg/mL) higher than the conventional Indomethacin (IC50 0.08 ± 0.003 µg/mL), and Celecoxib (IC50 0.79 ± 0.029 µg/mL). Additionally, the cytotoxicity test of Cs-SBBr NPs showed cytotoxic effect on Vero cells (CCL-81) with IC50 = 17.95 ± 0.12 µg/mL which is regarded as a safe compound. Therefore, Cs-SBBr NPs may become an alternative to cure H. pylori and prevent gastric cancer.

RESUMEN

AIM: This study aimed to investigate the feasibility of implementing a psychological first aid intervention for psychological distress, resilience capacity, quality and meaning of life among survivors affected by earthquake adversity in Northern Syria. METHODS: A quasi-experimental, pre-posttest, two-group research design was utilized. A convenience sample of 95 survivors (46 in the study group and 49 in the control group) was recruited for the psychological First Aid intervention at a 1:1 ratio. The psychological first aid intervention was delivered in 10 sessions, twice weekly, followed by 3-month follow-up. RESULTS: A statistically significant improvement in the mean scores of resilience capacity, quality and meaning of life among survivors, along with a significant reduction in psychological distress, was registered among the study group compared with the control group. CONCLUSION: Our work verified the suitability of implementing psychological first aid following the catastrophic temblors which struck Northern Syria. Given that the psychological first aid intervention is grounded in psychological safety, cognitive reframing, mobilization of social support and installation of hope, the feasibility of its path following public health emergency, traumatic events or even a personal crisis can be favourable.

RESUMEN

A new series of chromone and furochromone-based sulfonamide Schiff's base derivatives 3-12 were synthesized and evaluated for their antimicrobial activity against S. aureus, E. coli, C. albicans, and A. niger using agar diffusion method. Compound 3a demonstrated potent antimicrobial activities with MIC values of 9.76 and 19.53 µg/mL against S. aureus, E. coli and C. albicans, which is 2-fold and 4-fold more potent than neomycin (MIC = 19.53, 39.06 µg/mL respectively). To improve the effectiveness of 3a, it was encapsulated into chitosan nanoparticles (CS-3aNPs). The CS-3aNPs size was 32.01 nm, as observed by transmission electron microscope (TEM) images and the zeta potential value was 14.1 ± 3.07 mV. Encapsulation efficiency (EE) and loading capacity (LC) were 91.5 % and 1.6 %, respectively as indicated by spectral analysis. The CS-3aNPs extremely inhibited bacterial growth utilizing the colony-forming units (CFU). The ability of CS-3aNPs to protect skin wounds was evaluated in vivo. CS-3aNPs showed complete wound re-epithelialization, hyperplasia of the epidermis, well-organized granulation tissue formation, and reduced signs of wound infection, as seen through histological assessment which showed minimal inflammatory cells in comparison with untreated wound. Overall, these findings suggest that CS-3aNPs has a positive impact on protecting skin wounds from infection due to their antimicrobial activity.

RESUMEN

Aging-related sarcopenia is a degenerative loss of strength and skeletal muscle mass that impairs quality of life. Evaluating NUDT3 gene and myogenin expression as new diagnostic tools in sarcopenia. Also, comparing the concomitant treatment of resistance exercise (EX) and creatine monohydrate (CrM) versus single therapy by EX, coenzyme Q10 (CoQ10), and CrM using aged rats. Sixty male rats were equally divided into groups. The control group, aging group, EX-treated group, the CoQ10 group were administered (500 mg/kg) of CoQ10, the CrM group supplied (0.3 mg/kg of CrM), and a group of CrM concomitant with resistance exercise. Serum lipid profiles, certain antioxidant markers, electromyography (EMG), nudix hydrolase 3 (NUDT3) expression, creatine kinase (CK), and sarcopenic index markers were measured after 12 weeks. The gastrocnemius muscle was stained with hematoxylin-eosin (H&E) and myogenin. The EX-CrM combination showed significant improvement in serum lipid profile, antioxidant markers, EMG, NUDT3 gene, myogenin expression, CK, and sarcopenic index markers from other groups. The NUDT3 gene and myogenin expression have proven efficient as diagnostic tools for sarcopenia. Concomitant treatment of CrM and EX is preferable to individual therapy because it reduces inflammation, improves the lipid serum profile, promotes muscle regeneration, and thus has the potential to improve sarcopenia.

RESUMEN

BACKGROUND: Emphasizing the crucial significance of maintaining a national nursing workforce well-prepared with the necessary knowledge, skills, and abilities to respond effectively is the growing frequency of natural and environmental disasters, coupled with public health emergencies such as the COVID-19 pandemic. So, the study aimed to explore pediatric nurses' preparedness to monkeypox outbreak, and their stress during this outbreak in Egypt. METHODS: A cross-sectional study was conducted on a 416 nurses direct care for children at selected governmental hospitals in Egypt. Demographic form, Questionnaire for Infectious Disease Outbreak Readiness & Preparedness, factors affecting nurses' preparedness, and the generalized anxiety disorders scale-7 were the tools of the study. RESULTS: (81.5%) of studied nurses had unsatisfactory level of preparedness to monkeypox outbreak. (96.4%) and (95.4%) of them were affected their preparedness by high workload and inconsistent income with the of risk of infection factors. Also, (57.2%) of them had high stress level. CONCLUSIONS: The study revealed the importance of ensuring adequate supplies of PPE are available and provided, and protocols must be implemented to ensure availability in case of an outbreak. Moreover, nurse staffing levels and workload distribution should be regularly reviewed to create reasonable nurse-patient ratios.

RESUMEN

Designing highly adsorptive materials for wastewater treatment via facile approaches is still challenging. To boost the recovery of heavy metals from wastewater, surface and structure modification are considered a successful route. Herein, we report the design of ZnO nanoparticles by a simple thermal decomposition method followed by grafting Cu nanoparticles (Cu NPs) over the ZnO surface. Cu/ZnO was prepared with different Cu ratios, 0.01 and 1%. It was found that incorporating Cu into ZnO improved the porosity and surface area of ZnO. The adsorption ability of Cu/ZnO compared with bare ZnO was studied towards removing manganese ions from wastewater. The effects of several parameters, such as pH, temperature, contact time, and initial ion concentrations, were studied. The maximum removal of manganese was found at pH 2, 20 °C after 60 min in the presence of 1 g/L adsorbent. The role of Cu grafted on the surface of ZnO was discussed. The rates of adsorption were found to follow the pseudo-second-order model. The results showed better fitting to Freundlich isotherm. The thermodynamic study revealed that the sorption process is spontaneous, exothermic, and favorable at low temperatures. The free energy (ΔG°), enthalpy (ΔH°), and entropy (ΔS°) changes were calculated to predict the nature of adsorption.

RESUMEN

INTRODUCTION: Cariprazine is an orally active dopamine D3-preferring D3/D2 receptor and serotonin 5-HT1A receptor partial agonist, being considered as a treatment for refractory MDD. Therefore, we aim to perform the first meta-analysis of current literature, to collate changes in depression from baseline and assess tolerability of adjunctive cariprazine in MDD populace. METHODS: PubMed, Embase, Google Scholar, ClinicalTrials.Gov, and Cochrane Library were searched from inception till 1st September 2023. RCTs of adult patients with refractory MDD under adjunctive cariprazine vs. placebo were included. Primary outcomes included improvement in MADRS, CGI-S, and HAM-D 17 scores. Secondary outcomes included treatment-emergent adverse events. The statistical analysis was performed using generic inverse variance with random-effects model. The overall risk ratios (RR) were calculated for dichotomous outcomes. RESULTS: A total of five RCTs were analysed, enrolling 2013 participants (cariprazine: 959 participants, Placebo: 1054). Supplementation of ADT with cariprazine demonstrated a significant improvement in MADRAS, CGI-S and HAMD-17 scores from baseline (LSMD: -1.88, 95% CI [-2.94, -0.83], p=0.0005), (LSMD: -0.18, 95% CI [-0.29, -0.07], p=0.002), and (LSMD: -0.96, 95% CI [-1.70, -0.21], p=0.01) respectively. Treatment with adjunctive cariprazine therapy demonstrated significantly increased incidence of akathisia, nausea, dizziness, fatigue, restlessness, somnolence, and tremors when compared with placebo. CONCLUSION: Our meta-analysis provides evidence supporting the efficacy of adjunctive cariprazine in patients with refractory MDD. However, it is essential to consider the safety profile of cariprazine, particularly the increased risk of adverse events. The vigilant monitoring and management of these side effects should be integrated into clinical practice to minimize discontinuation rates and optimize patient outcomes.

RESUMEN

INTRODUCTION: In patients with non-valvular atrial fibrillation (NVAF), mechanical occlusion of the left atrial appendage (LAA) using a permanently implanted device may be an effective alternative to oral anti-coagulants (OAC). To facilitate left atrial appendage closure (LAAC), multiple percutaneous devices have been proposed. Watchman Generation 2.5 and Amplatzer Amulet are the two most popular used devices for preventing stroke in patients with NVAF. We sought to compare safety and efficacy outcomes between Watchman 2.5 and Amplatzer Amulet in patients undergoing LAAC procedure. METHODS: We carried out a comprehensive and systematic search of the databases PubMed and Scopus, for all studies that compared the safety and efficacy of Watchman 2.5 and Amplatzer Amulet devices, from inception, till June 2023. We performed the statistical analysis using Review Manager (V.5.4.1 Cochrane Collaboration, London, United Kingdom). The safety outcomes of interest included device success, device-related thrombus, device embolization perioperatively and at follow-up, perioperative pericardial perfusion events, and perioperative cardiac tamponade events. Efficacy outcomes were all-cause mortality perioperatively and at follow-up, cardiovascular (CV) mortality at follow-up, stroke, major and minor bleeding events at follow-up, transient ischemic attack (TIA) in follow-up period, thromboembolic events in follow-up period, and peri-device leakage in perioperative period. All data was analysed using a random-effects model, and presented as risk ratios (RRs) with 95% confidence intervals (95%CIs). RESULTS: Regarding safety outcomes, device success was non-significantly reduced in Watchman group when compared with Amulet (RR 0.99, p = 0.57; I2 = 34%). In contrast, device-related thrombus was non-significantly increased in Watchman 2.5 group in comparison to Amulet (RR 1.44, p = 0.11; I2 = 0%). There was no significant difference between the devices in terms of device embolization in the perioperative (RR 0.36, p = 0.38; I2 = 22%) and follow-up (RR 2.24, p = 0.13; I2 = 0%) periods. Likewise, there was no significant difference in the risks of pericardial effusion (RR 0.98, p = 0.98; I2 = 0%), and cardiac tamponade (RR 0.65, p = 0.76; I2 = 62%) perioperatively. Regarding efficacy outcomes, no significant difference was observed in all-cause mortality between devices perioperatively (RR 0.51, p = 0.32; I2 = 0%) and at follow-up (RR 1.08, p = 0.56; I2 = 0%). CV-mortality was non-significantly reduced in Watchman group when compared with Amulet (RR 0.57, p = 0.20; I2 = 0%). The Amulet device was not superior to the Watchman device in terms of stroke at follow-up (RR 1.13, p = 0.63; I2 = 0%). Sub-group analysis showed comparable ischaemic and haemorrhagic stroke events between two devices. Furthermore, at follow-up, there was no significant difference in major (RR 1.06, p = 0.63; I2 = 0%) and minor bleeding events (RR 1.81, p = 0.17; I2 = 0%) between the two devices. No difference was observed for trans-ischemic attack (RR 1.89, p = 0.24; I2 = 0%) and thromboembolic events (RR 0.96, p = 0.96; I2 = 0%) at follow-up. No significant difference was observed between devices for peri-device leakage in perioperative period (RR 2.16, p = 0.05; I2 = 0%). CONCLUSION: The data suggested that LAAC is safe and efficacious procedure irrespective of device used, with generally low complication rates. Watchman generation 2.5 remains non-superior to Amplatzer Amulet in terms of safety and efficacy outcomes.

RESUMEN

AIMS: Motivational interviewing (MI) has been recognized as highly effective for treating chronic diseases and various conditions, with encouraging results demonstrating its effectiveness in promoting health behaviour change. The current study was proposed to evaluate the feasibility of MI on adherence to care practices, emotional intelligence (EI), and dispositional optimism among patients with permanent pacemakers. METHODS AND RESULTS: This study was a parallel arm randomized controlled trial. Seventy clients with permanent pacemakers were randomly allocated to a six-session MI intervention (n = 35) or a waiting list control group (n = 35). A statistically significant improvement in the mean scores of adherence to care practices, EI, and dispositional optimism, along with a significant reduction in pessimism, was registered among the study group compared with the control group. CONCLUSION: Following the intervention for 1- and 2-month follow-up measurements, there were statistically significant improvements in self-care practice adherence. After 1 month of intervention, there were statistically significant gains in EI and dispositional optimism, but at the 2-month follow-up measurement, this improvement had somewhat lessened. The findings suggest that MI may be a feasible and practical approach for improving adherence to care practices, EI, and dispositional optimism in patients with permanent pacemakers.

RESUMEN

Hepatocyte injury is assessed by serum aspartate transaminase and alanine transaminase estimation. In psychiatric populations, antipsychotic drugs (AD) are culprit in hepatic dysfunction. To assess transaminitis among psychiatric patients treated by AD. This cross-sectional study was conducted in Zagazig University Hospitals in Egypt, from December 2022 to February 2023. A total of 135 adult patients aged ≥ 18 years, were diagnosed with psychiatric disorders after exclusion of patients receiving any hepatotoxic drugs, viral hepatitis, having chronic liver or kidney diseases, diabetes mellitus, mental retardation, and pregnant females. Among the 135 patients, 104 (77.0%) were males. Their age was 32 ±â€…9, The most popular used class of AD was atypical AD 84 (62.2%). The overall incidence of transaminitis among patients receiving AD was 23/135 (17.04%) of patients; 13 (56.5%) were on atypical AD compared to 10 (43.5%) patients receiving combined AD, without any statistically significant difference. The use of AD in patients with psychiatric disorders is potentially safe with minimal transaminitis (
