CR significantly improved the participants adherence to healthy lifestyle behaviors and decreased the cardiac risk factors in patients with coronary artery disease.
Much research has found that smoking is one of the major risk factors for a variety of physical diseases and mental disorders; however, few studies have been conducted on smoking in Egypt. Furthermore, to the researcher's best knowledge, no study in Egypt has compiled data on smoking prevalence, motives, and levels of nicotine dependency. In order to fill in this gap, the current study has attempted to summarize the situation and construct an accurate picture of smoking in Egypt.
This cross-sectional study included 2000 Egyptian adults in Fayoum through a multistage cluster sampling technique. For data collection, the Socioeconomic Status Scale was deployed. In addition, Depression, Anxiety, Stress Scale (DASS), the Modified Reasons for Smoking Scale (MRSS), and Fagerstrom Test for Nicotine Dependence (FTND) were used. Data analysis performed using SPSS version 22.0. For qualitative data, Chi-square test was used to determine statistical significance. Bivariate Pearson correlation was used to test for thews a moderate to high level of nicotine dependence, with a higher level of dependency, smoking pleasure, stress reduction/ relaxation, and hand-mouth movement as motives for smoking. Furthermore, there was a correlation between nicotine dependence, on one hand, and depression and stress on the other.
Road traffic injuries (RTIs) are the second leading cause of mortality in Saudi Arabia. The high rate of RTIs puts a strain on rehabilitation services. Yet, little is known of the economic burden of nonfatal RTIs and rehabilitation services. This study, therefore, aims to describe the annual rehabilitation costs associated with RTIs at a local trauma center.
This study was conducted among all the 17 years or older patients hospitalized at King Abdulaziz Medical City in Riyadh following RTIs and required rehabilitation care. We included 299 patients who met the inclusion criteria and were followed for one year after discharge from the index hospital. The data was abstracted through retrospective review of patients' medical records. Selleck STAT3-IN-1 All rehabilitative services utilized by the healthcare system were recorded. To describe the economic burden, the mean, median, standard deviation, and interquartile range (IQR) were calculated. Total costs were aggregated for all patients to estimate overall costs.
The study he economic burden of rehabilitation services resulting from RTIs. Public health interventions are needed to reduce the burden of RTIs by dealing with their preventable causes and improving road safety measures. These findings may be useful to policymakers and researchers to support and improve rehabilitation services in Saudi Arabia.A new species of Goodyera (Orchidaceae) from Tibet, China, G.medogensis, is described and illustrated here. Molecular phylogenetic results based on one nuclear (ITS) and two plastid markers (matK and trnL-F) support the recognition of G.medogensis as a new species in GoodyerasubsectionReticulum. Morphologically, the novelty is most similar to G.biflora, G.vittata and especially to G.hemsleyana, but differs by the thick grid lines of the reticulations with a diffused margin on the adaxial surface of the leaf blades, the inflorescence with more flowers, the obliquely obovate-rhombic petals, the yellow or yellowish labellum without a lamella on the blade, and the shorter trichomes on the floral bracts, sepals and ovary. Finally, a key to the species of Goodyerasubsect.Reticulum in China is also provided.Pitcairniaabscondita sp. nov., known until now only from the Municipalities of Cabo Corrientes, Mascota, Puerto Vallarta, San Sebastián del Oeste and Talpa de Allende in the State of Jalisco, Mexico, is here described and illustrated. The new taxon was confused with P.imbricata for long time, but differs from this species by its green floral bracts with the apex divergent to spreading (vs. red and appressed) and by the appendiculate at the base chartreuse-green petals (vs. not appendiculate yellow petals). Images and a distribution map of the taxa are presented.Multisystem Inflammatory Syndrome in Children (MIS-C), representing a new entity in the spectrum of manifestations of COVID-19, bears symptomatic resemblance with Kawasaki Disease (KD). This review explores the possible associations between KD and the human coronaviruses and discusses the pathophysiological similarities between KD and MIS-C and proposes implications for the pathogenesis of MIS-C in COVID-19. Since 2005, when a case-control study demonstrated the association of a strain of human coronavirus with KD, several studies have provided evidence regarding the association of different strains of the human coronaviruses with KD. Thus, the emergence of the KD-like disease MIS-C in COVID-19 may not be an unprecedented phenomenon. KD and MIS-C share a range of similarities in pathophysiology and possibly even genetics. Both share features of a cytokine storm, leading to a systemic inflammatory response and oxidative stress that may cause vasculitis and precipitate multi-organ failure. Moreover, antibody-dependent enhancement, a phenomenon demonstrated in previous coronaviruses, and the possible superantigenic behavior of SARS-CoV-2, possibly may also contribute toward the pathogenesis of MIS-C. Lastly, there is some evidence of complement-mediated microvascular injury in COVID-19, as well as of endotheliitis. Genetics may also represent a possible link between MIS-C and KD, with variations in FcγRII and IL-6 genes potentially increasing susceptibility to both conditions. Early detection and treatment are essential for the management of MIS-C in COVID-19. By highlighting the potential pathophysiological mechanisms that contribute to MIS-C, our review holds important implications for diagnostics, management, and further research of this rare manifestation of COVID-19.
Pembrolizumab is widely used in advanced non-small-cell lung cancer (NSCLC) patients with positive programmed death-ligand 1 (PD-L1). However, efficacy evaluation along treatment by serial monitoring of circulating tumor DNA (ctDNA) using next-generation sequencing remained to be well studied.
Nine PD-L1 positive advanced NSCLC patients were prospectively enrolled and received pembrolizumab monotherapy. Pretreatment tissue and/or plasma samples were collected as baseline reference. Serial plasma samples were collected after 3 and 6 weeks of treatment as well as at disease progression. All samples underwent targeted next-generation sequencing.
The median progression-free survival (mPFS) and median overall survival (mOS) were 4.43 and 25.53 months, respectively. In total, 3 patients achieved partial response (PR) or stable disease (SD) for more than 6 months and were thus classified into the durable clinical benefit (DCB) group, whereas the rest 6 were grouped as nondurable benefit (NDB) patients. Molecular profiling of baseline samples revealed that
and
were the 2 most frequently mutated genes in all patients, whereas
and
mutations were enriched in DCB and NDB groups, respectively. Higher tumor mutational burden (TMB) was observed in DCB patients than NDB group. During serial ctDNA monitoring, 2 DCB patients showed a dramatic ctDNA reduction while 75% of NDB patients' ctDNA concentration increased at week 6. Several acquired mutations might contribute to the pembrolizumab resistance, including
frameshift and
nonsense mutations.
Genomic profiling of peripheral blood samples can be applied to dynamically monitor disease progression. The reduction in ctDNA concentration during treatment implied DCBs.

The incidence of small renal mass (SRM) increases, and the prognosis of SRM is poor once metastasized. Therefore, we conducted this study to assess the clinical and pathological characteristics of SRM to determine the risk factors that influence the metastasis and prognosis of SRM.
A small renal mass is defined as a solid tumor mass with the largest diameter of 4 cm or less on the pathological diagnosis. The metastasis is confirmed by imaging or pathological examination. We retrospectively included 40 patients with metastatic SRM (mSRM) treated in the department of urology of Peking University Third Hospital from October 2002 to October 2020. Meanwhile, 358 patients with nonmetastatic SRM treated in our hospital from January 2015 to December 2017 were selected as controls. Clinicopathologic features were compiled.
Multivariate logistic regression analysis showed that age (
 = .027, odds ratio [OR] = 1.037, 95% confidence interval [CI] 1.004-1.070), clinical symptoms (
 < .001, OR = 4.311, 95% CI 1.tastasis. And SRM with older age, poor preoperative basic renal function, pathological vascular invasion, and metastasis have worse OS.
SRM with advanced age, clinical symptoms, high pathological nuclear grade, and lymphatic invasion are more likely to have distant metastasis. And SRM with older age, poor preoperative basic renal function, pathological vascular invasion, and metastasis have worse OS.There is growing awareness of the need for mathematics and computing to quantitatively understand the complex dynamics and feedbacks in the life sciences. Although several institutions and research groups are conducting pioneering multidisciplinary research, communication and education across fields remain a bottleneck. The opportunity is ripe for using education research-supported mechanisms of cross-disciplinary training at the intersection of mathematics, computation, and biology. This case study uses the computational apprenticeship theoretical framework to describe the efforts of a computational biology lab to rapidly prototype, test, and refine a mentorship infrastructure for undergraduate research experiences. We describe the challenges, benefits, and lessons learned, as well as the utility of the computational apprenticeship framework in supporting computational/math students learning and contributing to biology, and biologists in learning computational methods. We also explore implications for undergraduate classroom instruction and cross-disciplinary scientific communication.Using calculations, we show that a proposed Cu(I)-mediated deconstructive fluorination of N-benzoylated cyclic amines with Selectfluor® is feasible and may proceed through (a) substrate coordination to a Cu(I) salt, (b) iminium ion formation followed by conversion to a hemiaminal, and (c) fluorination involving C-C cleavage of the hemiaminal. The iminium ion formation is calculated to proceed via a F-atom coupled electron transfer (FCET) mechanism to form, formally, a product arising from oxidative addition coupled with electron transfer (OA + ET). The subsequent β-C-C cleavage/fluorination of the hemiaminal intermediate may proceed via either ring-opening or deformylative fluorination pathways. The latter pathway is initiated by opening of the hemiaminal to give an aldehyde, followed by formyl H-atom abstraction by a TEDA2+ radical dication, decarbonylation, and fluorination of the C3-radical center by another equivalent of Selectfluor®. In general, the mechanism for the proposed Cu(I)- mediated deconstructive C-H fluorination of N-benzoylated cyclic amines (LH) by Selectfluor® was calculated to proceed analogously to our previously reported Ag(I)-mediated reaction.
