Rationale:Central nervous system(CNS)actinomycosis is rare,spreading hematogenously from distant infections.Cutaneous actinomycosis with skull/meninges spread is especially unusual.Patient concerns:A 57-year-old man presented with complaints of discharge from the back of his scalp for six months,an ataxic gait,and bilateral upper and lower limb weakness and numbness over the past 4-5 months.Diagnosis:CNS actinomycosis.Interventions:Intravenous injection of ceftriaxone followed by oral amoxicillin-clavulanic acid therapy.Outcomes:The patient was able to walk without support,with complete resolution of sinus discharge.Lessons:In patients presenting with discharging sinuses especially when accompanied by CNS symptoms,actinomycosis should be considered as a differential,along with tuberculosis,non-tubercular mycobacterial infection,and aspergillosis.Microbiological confirmation should be attempted wherever possible,for accurate diagnosis and treatment,as clinic-radiological picture alone may not differentiate these infections,as treatment of each is diametrically opposite and patients can be cured with timely and appropriate treatment. 展开更多

BACKGROUND Post-transplant diabetes mellitus(PTDM)adversely affects graft survival and is an independent predictor of adverse cardiovascular events.Observational studies in the general population as well as the post-transplant setting suggest an association between the plasma 25-hydroxyvitamin D[25(OH)D]level and onset of type 2 diabetes mellitus.Literature is very limited in the context of PTDM.AIM To study the relationship between vitamin D deficiency at the time of kidney transplant and PTDM in the post-transplant period.METHODS In this single center study,72 patients who underwent kidney transplant were included.Blood samples for serum vitamin D level were collected on the day of transplant and analyzed at the end of study.The LIAISON®25(OH)D assay was used for quantitative estimation of total 25(OH)D in the serum.PTDM was diagnosed by either fasting plasma glucose(>126 mg/dL),2-h post prandial plasma glucose(>200 mg/dL),or 2-h oral glucose tolerance test after 45 days post-transplant.Hemoglobin A1c was not used to diagnose PTDM.Vitamin D levels were labeled as sufficient(≥30.0 ng/mL),insufficient(20.0-29.9 ng/mL),and deficient(<20.0 ng/mL).Patients were reviewed at 45 days and 1 year post transplant for the occurrence of PTDM.RESULTS In our study cohort 72 patients completed the study.Overall,32(43.8%)patients developed PTDM during the follow up of 1 year,44(61.1%)patients had deficient(<20 ng/mL)25(OH)D levels.Twenty-six(81.2%)patients with PTDM had deficient vitamin D levels as compared with 18(45.0%)patients without PTDM(P=0.007).This association was also significant when univariable[odds ratio(OR)=5.3,95%confidence interval(CI):1.79-15.67,P=0.003)]and multivariable(OR=8.21,95%CI:2.19-30.75,P=0.002)regression analysis was performed.A higher proportion of subjects having PTDM(15.6%)had a positive family history of diabetes mellitus than the controls(2.5%)(P=0.045).However,this association did not persist in the multivariable regression analysis(OR=12.6,95%CI:0.86-185.4,P=0.065).CONCLUSION Deficient vitamin D levels(<20 ng/mL)were significantly associated with PTDM in the post kidney transplant setting.Further studies are needed to see the effect of vitamin D replacement on PTDM. 展开更多

Herein,we report the multi-metal atomic catalysts for solid-state dehydrogenation of MgH_(2).It aims to reveal the multi-element synergy in catalysts for solid-state hydrogen storage.The kinetic measurements and fitting reveal two mechanisms:one shows a maximum rate at the early stage,such as V and Cr;the other needs a temperature-sensitive preparation time for its maximum rate,such as Ni.The combina-tion of two catalyst components demonstrates the best kinetics:V and Cr boost the initial dehydrogena-tion,and Ni benefits the further hydrogen transfer which alleviates the rate of decay.This work provides guidelines for the design of multi-element doped catalysts for MgH_(2) dehydrogenation. 展开更多

Objectives:The objective of this study was to assess the impact of two relaxation techniques,the Jacobson’s progressive muscle relaxation technique(JPMR),and the Benson’s relaxation technique(BRT),on the levels of stress and anxiety experienced by patients undergoing coronary angioplasty.Materials and Methods:Quantitative research approach with quasi-experimental pre-test and posttest control group design was conducted with seventy coronary angioplasty patients from the Institute of Medical Science,and SUM Hospital,Bhubaneswar,Odisha.The participants were purposively selected and divided into Experimental Group 1(n=35)and Experimental Group 2(n=35).Each group received either BRT or JPMR for three consecutive days.Pretest and posttest data were collected using a structured demographic questionnaire and the modified depression anxiety stress scale-21.Results:Both BRT and JPMR significantly decreased the levels of stress and anxiety among patients undergoing angioplasty compared to baseline(P<0.05).However,there was no significant difference between the two techniques based on Fisher’s exact P value.This suggests that both interventions are effective in reducing stress and anxiety among angioplasty patients.Conclusion:BRT or JPMR are noninvasive,nonpharmacological interventions that effectively reduce stress and anxiety in patients undergoing angioplasty.These findings underscore the importance of incorporating relaxation techniques into nursing practice and hospital programs to enhance patient care and promote holistic well-being post-angioplasty. 展开更多

Aqueous-electrolyte-based zinc-ion batteries(ZIBs),which have significant advantages over other batteries,including low cost,high safety,high ionic conductivity,and a natural abundance of zinc,have been regarded as a potential alternative to lithium-ion batteries(LIBs).ZIBs still face some critical challenges,however,especially for building a reversible zinc anode.To address the reversibility of zinc anode,great efforts have been made on intrinsic anode engineering and anode interface modification.Less attention has been devoted to the electrolyte additives,however,which could not only significantly improve the reversibility of zinc anode,but also determine the viability and overall performance of ZIBs.This review aims to provide an overview of the two main functions of electrolyte additives,followed by details on six reasons why additives might improve the performance of ZIBs from the perspectives of creating new layers and regulating current plating/stripping processes.Furthermore,the remaining difficulties and potential directions for additives in aqueous ZIBs are also highlighted. 展开更多

Obesity,a global health concern,is associated with severe health issues like type 2 diabetes,heart disease,and respiratory complications.It also increases the risk of various cancers,including melanoma,endometrial,prostate,pancreatic,esophageal adenocarcinoma,colorectal carcinoma,renal adenocarcinoma,and pre-and post-menopausal breast cancer.Obesity-induced cellular changes,such as impaired CD8^(+)T cell function,dyslipi-demia,hypercholesterolemia,insulin resistance,mild hyperglycemia,and fluctuating levels of leptin,resistin,adiponectin,and IL-6,contribute to cancer development by promoting inflammation and creating a tumor-promoting microenvironment rich in adipocytes.Adipocytes release leptin,a pro-inflammatory substance that stimulates cancer cell proliferation,inflammation,and invasion,altering the tumor cell metabolic pathway.Adiponectin,an insulin-sensitizing adipokine,is typically downregulated in obese individuals.It has antipro-liferative,proapoptotic,and antiangiogenic properties,making it a potential cancer treatment.This narrative review offers a comprehensive examination of the molecular interconnections between obesity and cancer,draw-ing on an extensive,though non-systematic,survey of the recent literature.This approach allows us to integrate and synthesize findings from various studies,offering a cohesive perspective on emerging themes and potential therapeutic targets.The review explores the metabolic disturbances,cellular alterations,inflammatory responses,and shifts in the tumor microenvironment that contribute to the obesity-cancer link.Finally,it discusses poten-tial therapeutic strategies aimed at disrupting these connections,offering valuable insights into future research directions and the development of targeted interventions. 展开更多

Facial nerve schwannoma occurring within the parotid gland is a rare tumour. We report a case of schwannoma within the parotid gland in a young female patient, who underwent ultrasound and magnetic resonanceimaging(MRI) and subsequent surgical excision of the lesion. The lesion showed hyperintensity on T2-weighted and diffusion-weighted MRI. There was no adjacent lymphadenopathy. Although hyperintensity on diffusionweighted MRI could suggest malignant tumours, the characteristic "string sign" provided the clue for the diagnosis of schwannoma. 展开更多

Crystal planes of a catalyst play crucial role in determining the electrocatalytic performance for CO2 reduction.The catalyst SnO2 can convert CO2 molecules into valuable formic acid(HCOOH).Incorporating heteroatom N into SnO2 further improves its catalytic activity.To understand the mechanism and realize a highly efficient CO2-to-HCOOH conversion,we used density functional theory(DFT)to calculate the free energy of CO2 reduction reactions(CO2RR)on different crystal planes of N-doped SnO2(N-SnO2).The results indicate that N-SnO2 lowered the activation energy of intermediates leading to a better catalytic performance than pure SnO2.We also discovered that the N-Sn O2 (211)plane possesses the most suitable free energy during the reduction process,exhibiting the best catalytic ability for the CO2-to-HCOOH conversion.The intermediate of CO2RR on N-SnO2 is HCOO*or COOH* instead of OCHO*.These results may provide useful insights into the mechanism of CO2RR,and promote the development of heteroatomdoped catalyst for efficient CO2RR. 展开更多
