Chronic kidney disease (CKD) is characterized by persistent low-grade inflammation. Soluble CD14 (sCD14) is involved in many pathological conditions including inflammation and atherosclerosis. The present study aimed to assess the relation between sCD14 levels, subclinical atherosclerosis (SCA), inflammation and mortality in Egyptian hemodialysis (HD) patients.
The present longitudinal study included 62 HD patients. All patients were submitted to careful history taking, thorough clinical examination and laboratory assessment for high-sensitivity C-reactive protein (hsCRP) and sCD14. Carotid intima-media thickness (CIMT) was also assessed. Patients were followed for a maximum of 18 months. The primary outcome is patients' mortality. Data were statistically analyzed using standard descriptive, comparative, correlative and regression methods.
The present study was conducted on 62 HD patients. They comprised 34 males and 28 females with an age of 54.6 ± 9.0 years. At the end of follow up, 12 patients (19.4 %) died. It was shown that survivors had significantly lower hsCRP levels (104.2 ± 38.2 versus 134.1 ± 15.3 mg/dL, p <0.001), lower sCD14 levels (32.7 ± 10.3 versus 47.4 ± 18.4 µg/mL, p=0.02) and lower CIMT (1.32 ± 0.5 versus 1.5 ± 0.2 mm, p=0.049). sCD14 levels were significantly correlated with hsCRP (r=0.4, p=0.001) and CIMT (r=0.31, p=0.013). Multivariate analysis identified HD duration [HR (95% CI) 1.02 (1.0-1.04), p= 0.021] and sCD14 levels [HR (95% CI) 1.06 (1.0-1.12), p= 0.026] as significant predictors of patients' survival.
sCD14 levels in this cohort of HD patients are well-correlated with hsCRP levels and CIMT. In addition, they are significant predictor of patients' mortality.

Allergic rhinoconjunctivitis and asthma are the most common IgE-mediated diseases worldwide. Allergen-specific immunotherapy (AIT) is currently the only modifying treatment for these IgE-mediated diseases, in both children and adults. Subcutaneous immunotherapy is widely used, but in patients over 65 years old there may be an increased risk of adverse reactions and a worse response to treatment. Oral immunotherapy (OIT) has been proved to be effective and safe, but currently, in most countries, it has been licensed only for patients up to 65 years old based on its technical datasheet. No studies into the efficacy and safety of this type of immunotherapy in patients older than 65 years old have been published.
We present four patients older than 65 years old with a diagnosis of moderate seasonal rhinoconjunctivitis and moderate-persistent seasonal pollen-induced asthma. Off-label use of oral immunotherapy (OIT) for grass pollen was prescribed, due to the severity of their rhinoconjunctivitis symptoms and worsening of asthma symptoms during the spring. Improvement in the rhinoconjunctivitis and asthma symptoms was reported by all patients since the first spring season and was maintained during the following two years of follow-up. There were no systemic reactions and only two patients initially had self-limiting oral pruritus Conclusion Oral immunotherapy for pollens appears to be a convenient, effective, and safe option in older patients (>65 years) with comorbidities after a three-year treatment. This is, to the best of our knowledge, the first report of the off-label use of OIT in patients over 65 years old with symptoms of allergic rhinoconjunctivitis and asthma.

COVID-19 vaccines are now accessible to all Indian citizens. Infection with COVID-19, on the other hand, continues to spread constantly. Our study aimed to determine the number of persons who had COVID-19 infections despite receiving the recommended number of doses of the COVID-19 vaccination at AIIMS Rishikesh, a tertiary care facility in Uttarakhand, India.
We analysed meticulously preserved data regarding COVID-19 vaccination, COVID-19 infection, clinical symptoms, and RT-PCR testing among all HCWs in our healthcare institution from 16 January 2021 to 30th June 2021.
During this period, 5273 (90.3%) HCWs received two doses of the COVID-19 vaccine, while 566 (9.7%) received only one dose. 628 HCWs (10.8%) were BBV152 recipients and 5211 (89.2%) were AZD1222 (ChAdOx1-S) recipients. 423 HCWs (7.2%, confidence interval of 95% - 13.8, 22.0) reported COVID-19 infections. 274 (5.19% of total vaccinated HCWs) breakthrough infections and 149 non-breakthrough COVID-19 infections were reported in HCWs who had previously received a single dose of the COVID-19 vaccination.
Viral infections, especially breakthrough infections, following adequate vaccination, are a cause for concern, but there is a lack of data on these infections in the actual world. Therefore, the primary focus of research should be on the emergence of illness in India following the completion of a full vaccine course.

These scaffolds have led to prominent applications in designing advanced soft materials, 3D printing, ion sensing, drug delivery, photonics, separation, and purification. In this review, we mainly emphasize on the different mechanistic aspects of triazole formation which includes synthesis of sugar-based and non-sugar-based triazoles, and their gel applications reported in the literature for the past ten years, as well as the upcoming scope in different branches of applied sciences.Cancer is the second most source of cessation of life globally with 9.6 million expirations each stage around the globe. The resistance to the current chemotherapies urges the researchers to develop new drugs to be available in the market. Among the wide range of drugs synthesized, heterocyclic compounds play a major role due to the abundance of heterocyclic rings in biological substances. In medicinal chemistry, benzimidazole is an important pharmacophore and a privileged structure. This bicyclic compound is made up of the fusion of a six-membered benzene ring and a five-membered imidazole ring with two nitrogen atoms at 1,3-positions. The benzimidazole ring has a great deal of stability. Many strong acids and alkalis do not affect benzimidazoles. Only under extreme conditions does benzimidazoles benzene ring cleave. Except in certain circumstances, the benzimidazole ring is also quite resistant to reduction. It is the most popular nucleus to study because of its wide range of biological functions. The recently developed methods for preparing benzimidazoles, such as condensation of o-phenylene diamines (OPDs) with aldehydes and many others using a wide range of nano, metal-based catalysts under solvent-free conditions, are discussed in detail in the current studies.
A simple pH and redox dual stimuli-responsive diketopyrrolopyrrole (DPP)-Cu2+ complexes gated mesoporous silica nanoparticles (MSN) were prepared for precise drug delivery and controlled drug release.
MSN was prepared by sol-gel method and then laminated. Carboxylic acid (CA)-Pyrrolo[3,4-c] pyrrole-1,4-dione, 2,5-dihydro-3,6-di-2-pyridinyl (PyDPP) was grafted onto the surface of amino-functionalized MSN (MSN-NH2) through a simple amide reaction and then complexed with Cu2+ to form gated molecules after doxorubicin (DOX) loading.
Scanning electron microscopy (SEM), transmission electron microscopy (TEM), and Low-angle X-ray diffraction (XRD) showed that MSN with uniform particle size (100 nm) and porous structure was successfully prepared. The prepared MSN, MSN-NH2, and MSN-DPP were fully characterized by Zeta potential, Fourier transforms infrared spectroscopy (FTIR), X-ray photoelectron spectroscopy (XPS) and nitrogen adsorption-desorption. High DOX-loading capacity (18.22%) and encapsulation efficiencture.
Synovial chondromatosis is an uncommon benign condition characterized by synovial membrane proliferation and metaplasia. Synovial chondromatosis cases in patients with rheumatoid arthritis have been reported. However, involvement of the glenohumeral joint is rare.
We herein report a case of a rare association of synovial chondromatosis involving the shoulder in a rheumatoid arthritis patient. The symptoms have improved with anti-tumor necrosis factor drugs. Consequently, there was no need for invasive therapy for treating synovial chondromatosis.
Synovial chondromatosis can be aggressive and destructive. More trials are needed to establish a better clinical diagnostic strategy and pharmacological management.

Air pollution is one of the environmental factors that influences the pathogenesis of systemic autoimmune diseases, followed by the development and spread of inflammation and increased oxidative damage. Only a few studies have been conducted on the impact of air pollution on disease activity in patients with lupus, which mostly have focused on PM2.5 particles.
We longitudinally studied 50 patients with lupus bimonthly in a 6-month period in Mashhad; one of the polluted cities of Iran. Disease activity and quality of life were examined according to SLEDAI2K, SLEQOL, and VAS criteria. The outdoor air pollutant was measured by monitoring the average concentration of nitrogen dioxide (NO2), carbon monoxide (CO), some particles less than 10 and 2.5 micrometers in diameter (PM <10, PM <2.5) and the level of temperature and humidity which were taken from the Meteorological Organization of Mashhad. Confounding factors such as medications were investigated by univariate and multivariate statistical analysis, specifically by GEE method.
The possible relation among various factors to SLEDAI, SLEQOL and VAS by two different univariate and multivariate analysis were studied. Our analysis indicated that spring season, decreased temperature, increased air pollutants including (PM2.5, and NO2) and increased humidity increase SLEDAI2K. Furthermore, the percent of polluted days directly correlates with Anti-dsDNA and NO2 significantly increases SLEQOL.
Based on our findings, air pollution (particularly NO2 and PM2.5) has affected at least some aspects of the disease and the health-related quality of life (HRQL) of lupus patients. Further research is needed to confirm these findings.
