Unprecedented iron-assisted room temperature synthesis of AgCN using acetonitrile.

A straightforward and convenient approach for producing AgCN at room temperature using acetonitrile as a source has been developed, employing various iron salts. To date, there have been no prior studies documenting the synthesis of AgCN by cleaving the C-CN bond in acetonitrile with the use of iron salts. The resulting highly crystalline material was subjected to characterization through XRD and FT-IR analysis. Additionally, the same process was used for C-CN bond breaking using Ag2S or via the formation of an AgSxOy composite. Consequently, this report is primarily dedicated to exploring the efficacy of different iron salts in breaking the C-CN bond in CH3CN. A theoretical investigation of the proposed experimental scheme has also been performed to confer the feasibility of the reaction.

Expert eValuation of Efficacy and Rationality of Vildagliptin "EVER-Vilda": An Indian Perspective.

Vildagliptin, a dipeptidyl peptidase-4 (DPP-4) inhibitor is effective in reducing HbA1c levels in patients with type 2 diabetes (T2DM) when administered as monotherapy, dual or triple combination therapy. In India, Vildagliptin is commonly prescribed in T2DM patients because it reduces mean amplitude of glycemic excursion (MAGE), has lower risk of hypoglycemia and is weight neutral. Early combination therapy with vildagliptin and metformin is effective and well-tolerated in patients with T2DM, regardless of age or ethnicity. In view of already existing data on vildagliptin and the latest emerging clinical evidence, a group of endocrinologists, diabetologists and cardiologists convened for an expert group meeting to discuss the role and various combinations of vildagliptin in T2DM management. This practical document aims to guide Physicians and Specialists regarding the different available strengths and formulations of vildagliptin for the initiation and intensification of T2DM therapy.

An Integrative Approach to Study the Inhibition of Providencia vermicola FabD Using C2-Quaternary Indolinones.

Background: The present study investigates the potential bioactivity of twelve experimentally designed C-2 quaternary indolinones against Providencia spp., a bacterial group of the Enterobacteriaceae family known to cause urinary tract infections. The study aims to provide insights into the bioactive properties of the investigated compounds and their potential use in developing novel treatments against Providencia spp. The experimental design of indolinones, combined with their unique chemical structure, makes them attractive candidates for further investigation. The results of this research may contribute to the development of novel therapeutic agents to combat Providencia spp. infections. Methods: The synthesized indolinones (moL1-moL12) are evaluated to identify any superior activity, particularly focusing on moL12, which possesses aza functionality. The antimicrobial activities of all twelve compounds are tested in triplicates against six different Gram-positive and Gram-negative organisms, including P. vermicola (P<0.05). Computational methods have been employed to assess the pharmacokinetic properties of the compounds. Results: Among the synthesized indolinones, moL12 exhibits superior activity compared to the other compounds with similar skeleton but different functional moieties. All six strains tested, including P. vermicola, demonstrated sensitivity to moL12. Computational studies support the pharmacokinetic properties of moL12, indicating acceptable absorption, distribution, metabolism, excretion, and toxicity characteristics. Conclusion: Utilizing the PPI approach, we have identified a promising target, FabD, in Gram-negative bacteria. Our analysis has shown that moL12 exhibits significant potential in binding with FabD, thereby, might inhibit cell wall formation, and display superior antimicrobial activity compared to other compounds. Consequently, moL12 may be a potential therapeutic agent that could be used to combat urinary tract infections caused by Providencia spp. The findings of this research hold significant promise for the development of new and effective treatments for bacterial infections.

Diabetes in India's North East Study: Prevailing Insulin Usage and Insulin Injection Practices amongst Type 2 Diabetes Mellitus Patients.

OBJECTIVE: Insulin therapy is mostly advised in patients with poorly controlled type 2 diabetes mellitus (T2DM). However, wide variation exists in insulin practice and usage across the Indian geography. MATERIALS AND METHODS: In this cross-sectional study, a retrospective audit of the medical records of T2DM patients who were receiving insulin and attending an urban referral clinic in Northeast India during the period from 2006 to 2017 was conducted to analyze the insulin utilization pattern and injection technique variation. A total of 1,454 patients were included, 60% were male and 40% were female. RESULTS: At presentation, the mean duration of T2DM was 12.13 (7.45) years. Insulin with or without oral anti-diabetic (OADs) was received by 52.27% and 47.73% of patients, respectively. The majority (62.93%) used a pen device for insulin administration. The patient-reported reasons for insulin therapy initiation were OAD failure (33.15%), glucotoxicity (30.26%) and diabetesassociated complications (20.36%). The mean ± standard deviation (SD) total daily dose (TDD) of insulin was 33.05 ± 17.09 (0.53 ± 0.30 units/kg/day). The breakup for the number of injection(s) per day was one (234,16.09%), two (970,66.71%), three (166,11.42%), four (78, 5.36%), and five (6, 0.41%). The majority (67.88%) used premixed insulin, while 10.90% used basal insulin alone. Compared to those without lipohypertrophy (LH), patients with LH were less likely to rotate the site of injection (0.85 vs 17.90%; p = 0.000), space the injections (10.71 vs 23.91%; p = 0.000), injected less often in correct site (7.81 vs 29.0%; p = 0.000), more likely to use wrong angles (10.08 vs 22.73%; p = 0.000) and reuse the needles (5.63 vs 14.86%; p = 0.000). Also, 34.87% of patients were not storing their insulin device at the right temperature and 8.87% experienced at least one episode of a hypoglycemic event. CONCLUSION: This audit depicts important attributes of current injection practices amongst T2DM patients on insulin and suggests the possible benefits of adopting correct practices for avoiding complications such as LH and hypoglycemia.

The Bariatric Pyramid: A framework for therapeutic targets.

The Bariatric Pyramid is a model which serves to explain the goals of obesity management, act as a milestone for monitoring of therapy, and to benchmark the utility of various anti-obesity medications and interventions. Built upon a base of sustainability, it lists three more desired aspects of care: sufficiency (sufficient strength) safety and security. Each of the four aspects of the pyramid: sustainability, sufficiency safety and security have three angles, which allows the reader to understand them easily. The model that we propose is useful in training health care professionals, in therapeutic patient education, for assessing various anti-obesity therapies, and in reaching the right decision while managing obesity.

Addendum 1: Forum for Injection Technique and Therapy Expert Recommendations, India.

With the emerging complexities in chronic diseases and people's lifestyles, healthcare professionals (HCPs) need to update their methods to manage and educate patients with chronic lifestyle disorders, particularly diabetes. The insulin injection technique (IIT), along with various parameters, must also be updated with newer methods. Forum for Injection Technique and Therapy Expert Recommendations (FITTER), India, has updated its recommendations to cover newer ways of detecting hypoglycaemia and lipohypertrophy, preventing needlestick injuries (NSIs), discouraging the reuse of insulin needles and encouraging good disposal. FITTER, India, is also introducing recommendations to calculate insulin bolus dose. These updated recommendations will help HCPs better manage patients with diabetes and achieve improved outcomes.

C-Reactive Protein Level can be a Better Indicator than Erythrocyte Sedimentation Rate in Assessing the Severity of Inflammation and Guiding Glucocorticoid Therapy in Subacute Thyroiditis.

Background: Despite the widespread use of several diagnostic tests in subacute thyroiditis (SAT), their usage remains largely subjective. C-reactive protein (CRP) and erythrocyte sedimentation rate (ESR) are useful indicators of inflammation in patients with SAT. The purpose of this study was to compare the scope for utilising CRP and ESR objectively in deciding the requirement of glucocorticoid therapy. Methods: A total of 28 patients with SAT were included in this study. Serum CRP and ESR were measured in all the patients. The characteristics of these tests were assessed firstly by using previously accepted positivity criterion for the particular diagnostic test. The area under the receiver operating characteristics (ROC) curve was obtained to provide an index of the overall discriminative ability of both tests. Results: Fifteen out of 28 patients were found to have features of significant thyroid inflammation eventually requiring glucocorticoid based on the current recommendations. The mean CRP value was significantly higher in patients requiring glucocorticoids. The ROC curves indicated that the optimal positivity criterion was 19.3 mg/L for the CRP level and 46 mm at the 1st hour for ESR. CRP with a sensitivity of 0.67, a specificity of 0.92, a positive likelihood ratio of 8.67, and an accuracy of 0.64 appeared better than ESR, which showed a sensitivity of 0.93, a specificity of 0.53, a positive likelihood ratio of 2.02, and an accuracy of 0.60. Conclusions: The serum CRP level provided a clear advantage over ESR in the assessment of the severity of inflammation before initiation of glucocorticoid therapy in SAT. However, a well-powered study is needed to examine the clinical relevance of such a role for CRP in thyroidology.

Incorporating Integrated Personalised Diabetes Management (iPDM) in Treatment Strategy: A Pragmatic Approach.

Diabetes is a global public health concern. Vigilant monitoring and effective management of glycaemic variations are essential to prevent complications of diabetes. Effectively incorporating monitoring strategies in management of diabetes is a serious challenge. Patient-centered approach is necessary to customise monitoring and therapy of diabetes. This has been made possible by integrating technology with personalised therapeutic strategy. The integrated personalised diabetes management (iPDM) is a holistic, patient-centered approach that focuses on personalising diabetes management to streamline therapy and improve outcome. iPDM helps strengthen the care process, facilitates communication between patients and their healthcare team, and integrates digital tools that visualise and analyse data. The five E's which includes enthusiasm, education, expertise, empathy and engagement are the key pillars of a strong foundation for the iPDM model. iPDM model is a convenient and easily accessible tool that shifts the management paradigm from an "algorithmic" to "personalized" care to optimise treatment outcomes. Structured self-monitoring of blood glucose (SMBG) should be available as part of the self-management process for people with sub-optimally controlled type 2 diabetes, including those not on insulin therapies. Different SMBG regimens should be followed based on factors such as diabetes type, treatment approach (diet, oral antidiabetic medication, or insulin), glycaemic control, available resources, and patient's level of education.

An Expert Group Consensus Statement on "Approach and Management of Prediabetes in India".

The prevalence of prediabetes, a forerunner of diabetes is very high, and its conversion to diabetes is also more rapid among Asian Indians. Prediabetes also predisposes to the development of macrovascular and to a lesser extent of microvascular complications of diabetes. In a large community-based epidemiological study, the Indian Council of Medical Research-India Diabetes (ICMR-INDIAB), data reported an overall prevalence of prediabetes of 10.3%, derived from 15 Indian states. This shows that the diabetes epidemic is far from over as many of them may soon convert to diabetes. Prediabetes, however, should not be considered a path to diabetes rather it should be a window of opportunity for the prevention of diabetes. This early screening, detection, and treatment of prediabetes should be made a national priority. Several countries have introduced lifestyle programs to prevent diabetes and, when indicated, pharmacological intervention with metformin as well. This consensus statement outlines the approaches to screening and lifestyle and pharmacological management of prediabetes in Asian Indians.

Human centered diabetes care.

This communication describes the concept of human centred diabetes care. It makes a distinction between patient centred and person centred care on one hand, and human centred care on the other. Human centred diabetes care is a grounded concept, which encompasses the philosophy of patient centred care, and blends it with a humanistic approach to management. It encourages the health care provider to view the person, living with diabetes, as a human being, and as part of a family, community and society. It also reminds the provider about his or her strengths and shortcomings, both of which are part of being human, and encourages him or her to strive towards becoming a better diabetes care provider, as well as human being. The human care model is relevant to all health delivery, and especially to chronic care such as diabetes management.

Chirally modified cobalt-vanadate grafted on battery waste derived layered reduced graphene oxide for enantioselective photooxidation of 2-naphthol: Asymmetric induction through non-covalent interaction.

The cobalt oxide-vanadium oxide (Co3O4-V2O5) combined with reduced graphene oxide (rGO) having band gap of âˆ¼ 3.3 eV appeared as a suitable photocatalyst for selective oxidation of 2-naphthol to BINOL. C2-symmetric BINOL was achieved with good yield using hydrogen peroxide as the oxidant under UV-light irradiation. The same catalyst was chirally modified with cinchonidine and a newly synthesized chiral Schiff base ligand having a sigma-hole center. The strong interaction of the chiral modifiers with the cobalt-vanadium oxide was truly evident from various spectroscopic studies and DFT calculations. The chirally modified mixed metal oxide transformed the oxidative CC coupling reaction with high enantioselectivity. High enantiomeric excess upto 92 % of R-BINOL was obtained in acetonitrile solvent and hydrogen peroxide as the oxidant. A significant achievement was the formation of S-BINOL in the case of the cinchonidine modified catalyst and R-BINOL with the Schiff base ligand anchored chiral catalyst. The UV-light induced catalytic reaction was found to involve hydroxyl radical as the active reactive species. The spin trapping ESR and fluorescence experiment provided relevant evidence for the formation of such species through photodecomposition of hydrogen peroxide on the catalyst surface. The chiral induction to the resultant product was found to induce through supramolecular interaction like OH…π, H…Br interaction. The presence of sigma hole center was believed to play significant role in naphtholate ion recognition during the catalytic cycle.

SGLT2-inhibition and Vascular Euphoria a Reconciliation of Vascular Health and Disease Homeostasis.

The concept of SGLT2-inhibition, once regarded as a non-physiological approach to glycemia control, now finds a foundational relevance in risk-modification for cardiovascular, kidney, and metabolic outcomes, spanning beyond type-2 diabetes. Major studies have proven meaningful improvements in various clinical outcomes, with different SGLT2-i agents. Apart from glycosuria, SGLT2-inhibition is associated with several patho-physiological effects, which may contribute to the clinical benefits seen with these agents. This narrative review is an attempt to appraise the different patho-physiological effects mediated by SGLT2-inhibition, based on contemporary evidence. The review classifies these effects in the acronym of EUPHORIA, and grades the possible relevance of each effect, in improving clinical outcomes.

Consensus on Medical Nutrition Therapy for Diabesity (CoMeND) in Adults: A South Asian Perspective.

Diabetes and obesity are both increasing at a fast pace and giving rise to a new epidemic called diabesity. Lifestyle interventions including diet play a major role in the treatment of diabetes, obesity and diabesity. There are many guidelines on dietary management of diabetes or obesity globally and also from South Asia. However, there are no global or South Asian guidelines on the non-pharmacological management of diabesity. South Asia differs from the rest of the world as South Asians have different phenotype, cooking practices, food resources and exposure, medical nutrition therapy (MNT) practices, and availability of trained specialists. Therefore, South Asia needs its own guidelines for non-pharmacological management of diabesity in adults. The aim of the Consensus on Medical Nutrition Therapy for Diabesity (CoMeND) in Adults: A South Asian Perspective is to recommend therapeutic and preventive MNT in the South-Asians with diabesity.

Metabolic and Energy Imbalance in Dysglycemia-Based Chronic Disease.

Metabolic flexibility is the ability to efficiently adapt metabolism based on nutrient availability and requirement that is essential to maintain homeostasis in times of either caloric excess or restriction and during the energy-demanding state. This regulation is orchestrated in multiple organ systems by the alliance of numerous metabolic pathways under the master control of the insulin-glucagon-sympathetic neuro-endocrine axis. This, in turn, regulates key metabolic enzymes and transcription factors, many of which interact closely with and culminate in the mitochondrial energy generation machinery. Metabolic flexibility is compromised due to the continuous mismatch between availability and intake of calorie-dense foods and reduced metabolic demand due to sedentary lifestyle and age-related metabolic slowdown. The resultant nutrient overload leads to mitochondrial trafficking of substrates manifesting as mitochondrial dysfunction characterized by ineffective substrate switching and incomplete substrate utilization. At the systemic level, the manifestation of metabolic inflexibility comprises reduced skeletal muscle glucose disposal rate, impaired suppression of hepatic gluconeogenesis and adipose tissue lipolysis manifesting as insulin resistance. This is compounded by impaired ß-cell function and progressively reduced ß-cell mass. A consequence of insulin resistance is the upregulation of the mitogen-activated protein kinase pathway leading to a pro-hypertensive, atherogenic, and thrombogenic environment. This is further aggravated by oxidative stress, advanced glycation end products, and inflammation, which potentiates the risk of micro- and macro-vascular complications. This review aims to elucidate underlying mechanisms mediating the onset of metabolic inflexibility operating at the main target organs and to understand the progression of metabolic diseases. This could potentially translate into a pharmacological tool that can manage multiple interlinked conditions of dysglycemia, hypertension, and dyslipidemia by restoring metabolic flexibility. We discuss the breadth and depth of metabolic flexibility and its impact on health and disease.

Clinical practice recommendations for the detection and management of hyperglycemia in pregnancy from South Asia, Africa and Mexico during COVID-19 pandemic.

The human coronavirus disease 2019 (COVID-19) pandemic has affected overall healthcare delivery, including prenatal, antenatal and postnatal care. Hyperglycemia in pregnancy (HIP) is the most common medical condition encountered during pregnancy. There is little guidance for primary care physicians for providing delivery of optimal perinatal care while minimizing the risk of COVID-19 infection in pregnant women. This review aims to describe pragmatic modifications in the screening, detection and management of HIP during the COVID- 19 pandemic. In this review, articles published up to June 2021 were searched on multiple databases, including PubMed, Medline, EMBASE and ScienceDirect. Direct online searches were conducted to identify national and international guidelines. Search criteria included terms to extract articles describing HIP with and/or without COVID-19 between 1st March 2020 and 15th June 2021. Fasting plasma glucose, glycosylated hemoglobin (HbA1c) and random plasma glucose could be alternative screening strategies for gestational diabetes mellitus screening (at 24-28 weeks of gestation), instead of the traditional 2 h oral glucose tolerance test. The use of telemedicine for the management of HIP is recommended. Hospital visits should be scheduled to coincide with obstetric and ultrasound visits. COVID-19 infected pregnant women with HIP need enhanced maternal and fetal vigilance, optimal diabetes care and psychological support in addition to supportive measures. This article presents pragmatic options and approaches for primary care physicians, diabetes care providers and obstetricians for GDM screening, diagnosis and management during the pandemic, to be used in conjunction with routine antenatal care.

Impact of Anti-Diabetic Medications on Quality of Life in Persons with Type 2 Diabetes Mellitus.

Introduction: Type 2 diabetes mellitus (T2DM) has been found to be associated with poor quality of life (QOL). The aim of this study was to measure QOL in T2DM patients and examine if the patients' socio demographic, diabetes-related clinical characteristics and insulin usage are associated with better quality of life. Materials and Methods: This clinic based cross-sectional study analyzed data from outpatients with T2DM attending a referral clinic between January and June 2016. Association between Diabetes Attitudes, Wishes and Needs (DAWN) QOL and few demographic, socioeconomic, clinical and biochemical predictors were examined using multivariate logistic regression model. A total of 518 patients completed the interview. Results: The HbA1c level of insulin ± oral anti-diabetic (OAD) cohort was significantly lower (7.89 ± 1.98) than the OAD cohort (8.79 ± 1.96), P < 0.001. Compared to their counterparts in the OAD cohort, patients on insulin were older with longer duration of diabetes mellitus. Co-morbid confounders like obesity, hypoglycemia, and blood pressure control or socio demographic confounders like income, education were almost similar in both the cohorts. The incidence of hypertension, coronary artery disease (CAD) and statin usage was significantly higher in the insulin cohort. The overall composite DAWN QOL scores of the insulin ± OAD cohort (25.42 ± 4.35) was marginally higher than that of the OAD cohort (23.62 ± 5.06) (P = 0.067). Analog insulin users were also found to have significantly higher composite DAWN QOL scores compared to human insulin users (25.77 ± 5.73 vs.24.13 ± 4.88, P = 0.037). Conclusions: The insulin cohort, despite being older and having longer duration of diabetes, had significantly higher diet compliance score, and enhanced QOL owing to better diabetes-related knowledge and treatment adherence characteristics than non-insulin users. Questionnaires-based evaluation of QOL can provide better understanding of the patient's experience of the illness, self-care, psychological and emotional functioning, and choice of therapeutic modality enhancing the quality of care.

Cardiometabolic vigilance in COVID-19 and resource husbandry in resource-challenged times: Clinical practice- based expert opinion.

BACKGROUND AND AIMS: The ongoing pandemic of coronavirus disease 2019 (COVID-19) is rapidly evolving, thereby posing a profound challenge to the global healthcare system. Cardiometabolic disorders are associated with poor clinical outcomes in persons with COVID-19. Healthcare challenges during the COVID-19 pandemic are linked to resource constraints including shortage of Personal Protective Equipment's (PPE), laboratory tests and medication. In this context, a group of clinical experts discussed the endocrine and cardiology vigilance required in times of COVID-19. Further, the group proposed certain resource husbandry recommendations to be followed during the pandemic to overcome the constraints. METHOD: The clinical experts discussed and provided their inputs virtually. The expert panel included clinical experts comprising endocrinologists, Consultant Physicians and cardiologists from India. The panel thoroughly reviewed existing literature on the subject and proposed expert opinion. RESULTS: The expert panel put forward clinical practice-based opinion for the management of cardiometabolic conditions including diabetes mellitus and hypertension. As these conditions are associated with poor clinical outcomes, the expert panel recommends that these persons be extra-cautious and take necessary precautions during the ongoing pandemic. Further, experts also provided appropriate, affordable, available and accessible solution to the resource constraint situations in times of COVID-19 pandemic. CONCLUSION: The clinical expert opinion put forward in this article will serve as a reference for clinicians treating diabetes and cardiovascular disease during the COVID-19 pandemic.
