Fabrication and characterizations of simvastatin-containing mesoporous bioactive glass and molybdenum disulfide scaffold for bone tissue engineering

Due to the limitations of the current treatment approaches of allograft and autograft techniques, treating bone disorders is a significant challenge. To address these shortcomings, a novel biomaterial composite is required. This study presents the preparation and fabrication of a novel biomaterial composite scaffold that combines poly (D, L-lactide-co-glycolide) (PLGA), mesoporous bioactive glass (MBG), molybdenum disulfide (MoS2), and simvastatin (Sim) to address the limitations of current bone grafting techniques of autograft and allograft. The fabricated scaffold of PLGA-MBG-MoS2-Sim composites was developed using a low-cost hydraulic press and salt leaching method, and scanning electron microscopy (SEM) analysis confirmed the scaffolds have a pore size between 143 and 240 μm. The protein adsorption for fabricated scaffolds was increased at 24 h. The water adsorption and retention studies showed significant results on the PLGA-MBG-MoS2-Sim composite scaffold. The biodegradation studies of the PLGA-MBG-MoS2-Sim composite scaffold have shown 54% after 28 days. In vitro, bioactivity evaluation utilizing simulated body fluid studies confirmed the development of bone mineral hydroxyapatite on the scaffolds, which was characterized using x-ray diffraction, Fourier transform infrared, and SEM analysis. Furthermore, the PLGA-MBG-MoS2-Sim composite scaffold is biocompatible with C3H10T1/2 cells and expresses more alkaline phosphatase and mineralization activity. Additionally, in vivo research showed that PLGA-MBG-MoS2-Sim stimulates a higher rate of bone regeneration. These findings highlight the fabricated PLGA-MBG-MoS2-Sim composite scaffold presents a promising solution for the limitations of current bone grafting techniques.

Understanding the Impact of Population and Cancer Type on Tumor Mutation Burden Scores: A Comprehensive Whole-Exome Study in Cancer Patients From India

PURPOSE

The purpose of this study was to understand the impact of population diversity and geographic variation on tumor mutation burden (TMB) scores across cancers and its implication on stratification of patients for immune checkpoint inhibitor (ICI) therapy.

MATERIALS AND METHODS

This retrospective study used whole-exome sequencing (WES) to profile 1,233 Indian patients with cancer across 30 different cancer types and to estimate their TMB scores. A WES-based pipeline was adopted, along with an indigenously developed strategy for arriving at true somatic mutations. A robust unsupervised machine learning approach was used to understand the distribution of TMB scores across different populations and within the population.

RESULTS

The results of the study showed a biphasic distribution of TMB scores in most cancers, with different threshold scores across cancer types. Patients with cancer in India had higher TMB scores compared with the Caucasian patients. We also observed that the TMB score value at 90th percentile (predicting high efficacy to ICI) was high in four different cancer types (sarcoma, ovary, head and neck, and breast) in the Indian cohort as compared with The Cancer Genome Atlas or public cohort. However, in lung and colorectal cancers, the TMB score distribution was similar between the two population cohorts.

CONCLUSION

The findings of this study indicate that it is crucial to benchmark both cancer-specific and population-specific TMB distributions to establish a TMB threshold for each cancer in various populations. Additional prospective studies on much larger population across different cancers are warranted to validate this observation to become the standard of care.

An assembly of TROP2-mediated signaling events

Trophoblast cell surface antigen 2 (TROP2) is a calcium-transducing transmembrane protein mainly involved in embryo development. The aberrant expression of TROP2 is observed in numerous cancers, including triple-negative breast cancer, gastric, colorectal, pancreatic, squamous cell carcinoma of the oral cavity, and prostate cancers. The main signaling pathways mediated by TROP2 are calcium signaling, PI3K/AKT, JAK/STAT, MAPKs, and β-catenin signaling. However, collective information about the TROP2-mediated signaling pathway is not available for visualization or analysis. In this study, we constructed a TROP2 signaling map with respect to its role in different cancers. The data curation was done manually by following the NetPath annotation criteria. The described map consists of different molecular events, including 8 activation/inhibition, 16 enzyme catalysis, 19 gene regulations, 12 molecular associations, 39 induced-protein expressions, and 2 protein translocation. The data of the TROP2 pathway map is made freely accessible through the WikiPathways Database ( https://www.wikipathways.org/index.php/Pathway:WP5300 ). Development of TROP2 signaling pathway map.

Management strategies for the painless foot drop: a systematic review of the literature

PURPOSE

Foot drop can uncommonly be a painless presenting symptom of degenerative spinal disorders. This systematic review aimed to summarise the literature on the management and outcomes of patients with a painless foot drop.

METHODS

We performed a systematic review of PubMed, EMBASE and Medline according to PRISMA guidelines. All studies published after 1980 in English referring to adult patients with a painless foot drop were included. Exclusion criteria included opinion based reports, review articles and articles in which foot drop was not caused by degenerative pathology of the thoracolumbar spine.

RESULTS

Of 62 included patients, 30 (48.4%) were male with an average age of 48.7 years (range 27-84). The mean duration of symptoms was 69.0 days (1-700). 98.8% were managed operatively. 46 (74.2%) patients had symptomatic improvement, with 41 (66.1%) having a post-intervention MRC power grading of 3 or above. Patients with a pre-procedure MRC 0 had a higher median increase in MRC post-procedure than those with MRC > 0. Of two studies comparing painful and painless symptoms, painless foot drop patients were less likely to recover to MRC equal to or over 3 than those with painful symptoms OR 0.31 (95% CI 0.04-2.65).

CONCLUSION

This systematic review and meta-analysis demonstrates a role for surgery in facilitating the neurological recovery of patients with a painless foot drop. Large randomised controlled studies are required to characterise the role of operative intervention in these patients and compare outcomes between patients with painless and painful foot drop.

Cohort profile: the ESC EURObservational Research Programme Non-ST-segment elevation myocardial infraction (NSTEMI) Registry

AIMS

The European Society of Cardiology (ESC) EURObservational Research Programme (EORP) Non-ST-segment elevation myocardial infarction (NSTEMI) Registry aims to identify international patterns in NSTEMI management in clinical practice and outcomes against the 2015 ESC Guidelines for the management of acute coronary syndromes in patients presenting without ST-segment-elevation.

METHODS AND RESULTS

Consecutively hospitalised adult NSTEMI patients (n = 3620) were enrolled between 11 March 2019 and 6 March 2021, and individual patient data prospectively collected at 287 centres in 59 participating countries during a two-week enrolment period per centre. The registry collected data relating to baseline characteristics, major outcomes (in-hospital death, acute heart failure, cardiogenic shock, bleeding, stroke/transient ischaemic attack, and 30-day mortality) and guideline-recommended NSTEMI care interventions: electrocardiogram pre- or in-hospital, pre-hospitalization receipt of aspirin, echocardiography, coronary angiography, referral to cardiac rehabilitation, smoking cessation advice, dietary advice, and prescription on discharge of aspirin, P2Y12 inhibition, angiotensin converting enzyme inhibitor (ACEi)/angiotensin receptor blocker (ARB), beta-blocker, and statin.

CONCLUSION

The EORP NSTEMI Registry is an international, prospective registry of care and outcomes of patients treated for NSTEMI, which will provide unique insights into the contemporary management of hospitalised NSTEMI patients, compliance with ESC 2015 NSTEMI Guidelines, and identify potential barriers to optimal management of this common clinical presentation associated with significant morbidity and mortality.

Omics Data Mining for multiPTMs in Oral Cancer: Cellular Proteome and Secretome of Chronic Tobacco-Treated Oral Keratinocytes

Oral cancer is common worldwide but lacks robust diagnostics and therapeutics. Lifestyle factors, such as tobacco chewing and smoking, are significantly associated with oral cancers. Mapping the changes in the global proteome, secretome and post-translational modifications (PTMs) during tobacco exposure of oral keratinocytes hold great potential for understanding the mechanisms of oral carcinogenesis, not to mention for innovation toward clinical interventions in the future. On the other hand, although advances in mass spectrometry (MS)-based techniques have enabled the deep mining of complex proteomes, a large portion of the mass spectrometric data remains unassigned. These unassigned spectral data can be researched for multiple post-translational modifications (multiPTMs). Using data mining of publicly available proteomics data, we report, in this study, a multiPTM analysis of high-resolution MS-derived datasets on cellular proteome and secretome of chronic tobacco-treated oral keratinocytes. We identified 800 PTM sites in 496 proteins. Among them, 43 PTM sites in 37 proteins were found to be differentially expressed, accounting for their protein-level expression. Enrichment analysis of the proteins with altered phosphosite expression and the known kinases of these phosphosites discovered the overrepresentation of certain biological processes such as splicing and hemidesmosome assembly. These findings contribute to a deeper understanding of omics level changes in chronic tobacco-treated oral keratinocytes, and by extension, pathophysiology of oral cancers.

Effect of prosthetic framework material, cantilever length and opposing arch on peri-implant strain in an all-on-four implant prostheses

Aim

To evaluate the effect of prosthetic framework material and cantilever length on peri-implant strain in mandibular all-on-four implant-supported prostheses with different types of arch antagonist forces.

Materials and Methods

Models simulating a completely edentulous mandibular arch fabricated in heat-cured acrylic resin were used. On the acrylic models, four implants were placed at regions 34, 32, 42, and 44 simulating all-on-four implant placements. Implant-supported screw-retained fixed prosthesis frameworks were fabricated using three different materials (cobalt-chromium, zirconia, and polyetheretherketone) and with three different cantilever lengths (zero mm, 15 mm, and 25 mm). Strain gauges were attached on the model at the buccal and lingual positions of each implant. Forces simulating opposing natural dentition, conventional complete denture, and the parafunctional habit were applied to the models. The peri-implant strain in each strain gauge was recorded.

Results

Least peri-implant strains (67 microstrains) were observed when forces simulating conventional complete dentures were applied on the models and the highest peri-implant strains (9091 microstrains) were observed when forces simulating parafunctional habit were applied. One-way ANOVA test followed by Tukey's post hoc analysis was performed to compare the mean deformation scores between different materials at 50 N load. The level of significance [P-value] was set at P < 0.05. Tests showed significant differences between zero mm and the other types in all the different materials, and also between 1.5 x AP and 2.5 x AP for Zirconia and Peek material at P = 0.02 & P = .008, respectively. The results showed that the type of framework material, cantilever length, and occlusal forces from the opposing arch influence the peri-implant strain in the bone in all-on-four implant-supported prostheses.

Conclusion

Rehabilitation of a single, completely edentulous arch with implant-supported prostheses should consider the situation of the opposing arch. The choice of framework material, as well as the cantilever length, should be altered based on the forces from the opposing arch.

Proteogenomic examination of esophageal squamous cell carcinoma (ESCC): new lines of inquiry

Introduction: Esophageal squamous cell carcinoma (ESCC), a histopathologic subtype of esophageal cancer is a major cause of cancer-related morbidity and mortality worldwide. This is primarily because patients are diagnosed at an advanced stage by the time symptoms appear. The genomics and mass spectrometry-based proteomics continue to provide important leads toward biomarker discovery for ESCC. However, such leads are yet to be translated into clinical utilities. Areas covered: We gathered information pertaining to proteomics and proteogenomics efforts in ESCC from the literature search until 2020. An overview of omics approaches to discover the candidate biomarkers for ESCC were highlighted. We present a summary of recent investigations of alterations in the level of gene and protein expression observed in biological samples including body fluids, tissue/biopsy and in vitro-based models. Expert opinion: A large number of protein-based biomarkers and therapeutic targets are being used in cancer therapy. Several candidates are being developed as diagnostics and prognostics for the management of cancers. High-resolution proteomic and proteogenomic approaches offer an efficient way to identify additional candidate biomarkers for diagnosis, monitoring of disease progression, prediction of response to chemo and radiotherapy. Some of these biomarkers can also be developed as therapeutic targets.

A network map of netrin receptor UNC5B-mediated signaling

UNC-5 Homolog B (UNC5B) is a member of the dependence receptor family. This family of receptors can induce two opposite intracellular signaling cascades depending on the presence or absence of the ligand and is thus capable of driving two opposing processes. UNC5B signaling has been implicated in several cancers, where it induces cell death in the absence of its ligand Netrin-1 and promotes cell survival in its presence. In addition, inhibition of Netrin-1 ligand has been reported to decrease invasiveness and angiogenesis in tumors. UNC5B signaling pathway has also been reported to be involved in several processes such as neural development, developmental angiogenesis and inflammatory processes. However, literature pertaining to UNC5B signaling is scarce and scattered. Considering the importance of UNC5B signaling, we developed a resource of signaling events mediated by UNC5B. Using data mined from published literature, we compiled an integrated pathway map consisting of 88 UNC5B-mediated signaling events and 55 proteins. These signaling events include 27 protein-protein interaction events, 33 catalytic events involving various post-translational modifications, 9 events of UNC5B-mediated protein activation/inhibition, 27 gene regulation events and 2 events of translocation. This pathway resource has been made available to the research community through NetPath ( http://www.netpath.org /), a manually curated resource of signaling pathways (Database URL: http://www.netpath.org/pathways?path_id=NetPath_172 ). The current resource provides a foundation for the understanding of UNC5B-mediated cellular responses. The development of resource will serve researchers to explore the mechanisms of UNC-5B signaling in cancers.

A Comparative Evaluation of Risk Factors and Various Antibiotic Regimens in Postoperative Neurosurgical Infections: A Prospective Randomized Controlled Study

Introduction Postoperative neurosurgical infections are a major problem, and the importance of keeping them to an absolute minimum cannot but be overemphasized. In this prospective study, we plan to evaluate the efficacy of three antibiotic regimens designed keeping the availability, affordability, and efficacy upon the common bacterial flora isolated at our center. We will also analyze the incidence and evaluate the risk factors of surgical site infections following clean, nonimplant, fresh, elective craniotomies.

Material and Methods This prospective randomized control study was conducted at our institute, a tertiary referral center, for a period of 2 years. The study cohort included all patients undergoing clean, nonimplant, fresh, elective craniotomies at our institute. The antibiotic protocol was chosen according to the current bacterio-epidemiological data based on the prevalence of infectious agent. One of the three drug regimens was chosen.

Results The results of univariate analysis revealed that there are multiple factors that are significantly associated with postoperative surgical site infection. In the multivariate analysis, only the presence of cerebrospinal fluid leak was the most significant factor associated with postoperative infections. Among the three different antibiotic regimens, cefazolin and amoxicillin–clavulanic acid were much better prophylactic agents for preventing surgical site infections when compared with cefotaxime.

Conclusion The present study has provided an insight into the incidence and risk factors contributing to surgical site infections as well as the efficacious antibiotic regimen protocols. The present study is one of the few studies to compare the efficacy of different antibiotic regimen protocols and also prospectively analyze the factors contributing to postoperative infections. This study will help us in optimizing the prophylaxis protocols and prevent emergence of multidrug-resistant strains, especially in a country like India.

Leiomyosarcoma : Case Report of a Rare Primary Smooth Muscle Tumour of the Thyroid Gland

Primary smooth muscle tumours of the thyroid gland are extremely rare neoplasms. There are concerns regarding the management of such disease due to its rarity. Around 22 cases have been reported in the literature till date. In this study, the case of a 63year old female patient who presented with a rapidly enlarging anterior neck mass over the period of 3 months is reported. The patient underwent thyroidectomy with tracheostomy and radiotherapy for the treatment of primary leiomyosarcoma of thyroid gland. Due to similar clinical presentation as anaplastic carcinoma, diagnosis of primary thyroid leiomyosarcomas is difficult and maybe misdiagnosed. Hence the combined assessment of clinical, imaging and pathological data is required.Immunohistochemical analysis is a gold standard for diagnosis. Diagnosis and treatment of the current patient with primary thyroid leiomyosarcomaand a comprehensive review of the relevant literature are presented herein

Increase in oxidative stress and mitochondrial impairment in hypothalamus of streptozotocin treated diabetic rat: Antioxidative effect of Withania somnifera

Hypothalamus, the primary brain region for glucose sensing, is severely affected by oxidative stress in diabetes mellitus. Oxidative stress in this region of brain may cause severe impairment in neuronal metabolic functions. Mitochondria are prominent targets of oxidative stress and the combination of increased oxidative stress and mitochondrial dysfunctions may further decline hypothalamic neuronal functions. In the present study we examined the oxidative damage response, antioxidative responses and mitochondrial membrane permeability transition in hypothalamus of streptozotocin-treated diabetic rats. Our results show that streptozotocin significantly increases hypothalamic lipid peroxidation, protein carbonyl content while glutathione peroxidase and reduced glutathione were declined. Mitochondrial impairment marked by an increase in mitochondrial membrane permeabilization was seen following streptozotocin treatment in the hypothalamus. The oral administration of Withania somnifera root extract stabilized mitochondrial functions and prevented oxidative damage in the hypothalamus of diabetic rat. These findings suggest an increase in the oxidative stress and decline in antioxidative responses in the hypothalamus of streptozotocin treated diabetic rats. Withania somnifera root extract was found useful in reducing oxidative stress and mitochondrial impairment in hypothalamus of diabetic rat.

Retrospective surveillance for intussusception in children aged less than five years at two tertiary care centers in India

BACKGROUND

A rotavirus vaccine could soon become part of India's national immunization program. However the occurrence of intussusception due to rotavirus vaccine is a potential safety concern. This surveillance aimed at the collection of baseline data on childhood intussusception which would facilitate the monitoring of intussusception cases after the introduction of rotavirus vaccines.

METHODS

We retrospectively reviewed medical records of confirmed intussusception cases in children under the age of five, treated during 2007-2012 at two tertiary care hospitals attached to medical schools in India. Demographic, clinical, diagnostic and treatment practices data were obtained from hospital records.

RESULTS

Over a five to six year observation period, we identified 187 confirmed cases of intussusception, of which 75% were males. The median age of intussusception was 8 months, and we observed a possible trend in the distribution of cases with the highest number of cases being reported in the month of April and lowest in the month of October. The most common diagnostic methods used were ultrasonography and abdominal radiography with most cases being treated surgically (71%). The median length of hospital stay was 8 days (range 1-40) and mean was 10.2 days. Records of any fatality due to intussusception were not found during the review of the records.

CONCLUSIONS

This analysis provides an estimate of the baseline data of childhood intussusception prior to the introduction of the rotavirus vaccination as a part of routine immunization in India. A prospective surveillance system using a standardized case definition is needed in order to better examine the incidence of intussusception in developing countries.

Variations in the cone packing density with eccentricity in emmetropes

AIM

To describe the parafoveal cone arrangement in emmetropic subjects and its variations with eccentricity, meridians and change in axial length in Indian eyes.

METHODS

We imaged 25 subjects using compact adaptive optics (AO) retinal camera prototype, the rtx1. Imaging was done at 1, 2, and 3° eccentricity from the fovea in four meridians: nasal, temporal, superior, and inferior.

RESULTS

A statistically significant drop in the cone packing density was observed from 2 to 3° (2° eccentricity=25 350/mm(2) (5300/mm(2), 8400-34 800/mm(2)) 3° eccentricity=20 750/mm(2) (6000 mm(2), 9000-33 670/mm(2))) P<0.05. The spacing correspondingly increased with increase in distance from the fovea (2° eccentricity=6.9 μm (0.70 μm, 5.95-11.6 μm)) and 3°eccentricity=7.80 μm (1.00 μm, 6.5-13.5 μm) P<0.05. As the axial length increases, the cone density significantly decreases. Interocular variations were noted.

CONCLUSION

With the advent of AO, visualization at the cellular level is now possible. Understanding the photoreceptor mosaic in the parafoveal space in terms of its density, spacing, and arrangement is crucial so as to detect early pathology and intervene appropriately. Newer therapeutic modalitites that are targeted at the cellular level like yellow micropulse laser, stem cells, gene therapy and so on may be better monitored in terms of safety and efficacy.

Wetting characteristics of addition silicon materials subjected to immersion disinfection--an in-vitro study

An in-vitro study was conducted to assess wetting characteristic of four brands of addition silicon materials subjected to immersion disinfection using four different disinfectants. Among the non-disinfected specimens, the lowest contact angle was recorded for Aquasil ultra (21.63), followed by Imprint II (29.06), Aquasil LV (44.10) and Take 1 (44.55). While 5.25% phenol increased the contact angle of all the silicon materials; 0.05% iodophor increased the angle of Take 1 and Imprint II and 0.5% sodium hypochlorite increased the angle of Imprint II and decreased for Aquasil ultra. However, 2% glutaraldehyde did not significantly change the contact angle of any of the four impression materials.

Pharmaceutical care: need of the hour in India

Pharmaceutical care signifies a shift of practice in pharmacy from being drug product-oriented to the one that is patient-oriented to achieve definite outcomes that improves patients’ quality of life. In order to achieve pharmaceutical care, pharmacists have to assume the role of caregiver, communicator, decision-maker, teacher, researcher, life-long learner, leader, and manager, which will help him to provide individualized care. As the patients visit community pharmacists more often, they can play a major role in providing individual care to the patients especially in the management of chronic noncommunicable diseases (NCDs). Community pharmacists have to upgrade their expertise in drug product orientation to that of clinical orientation to provide patient oriented care. Hence pharmacists have a larger role to play in managing NCDs which are rapidly increasing in India.

AGGRESSIVE MESENTRIC FIBROMATOSIS: A RARE CASE REPORT AND REVIEW OF LITERATURE

XERODERMA PIGMENTOSA WITH MULTIPLE CUTANEOUS MALIGNANCIES– A RARE CASE REPORT AND REVIEW OF LITERATURE

Xeroderma pigmentosa is a rare autosomal recessive disorder, characterized by photosensitivity, pigmentary changes, premature skin aging, and marked increase in risk of developing malignant neoplasms of the skin and eyes. Here we present a 13 year old girl with xeroderma pigmentosa who developed multiple cutaneous malignancies in the face and upper limb.

Physician perceptions and practices in management of diabetes in India: Results from the IMPROVE Control program

INTRODUCTION

The impact of IMPROVE Control Training program was evaluated by a non-interventional study and validated by a physician perception questionnaire. From a survey on 1086 physicians providing diabetes care in India, we report their practices and perceptions about diabetes care and insulin therapy.

MATERIALS AND METHODS

The responses were collected using a questionnaire validated by the IMPROVE Control Steering Committee.

RESULTS

Majority [558 (51.4%)] of the physicians accepted the ADA defined HbA1c target of <7% as the standard for good glycemic control in their practice. However, 541 (49.8%) of the physicians agreed that only 20-40% of their patients were able to achieve this target. For patients who do not achieve the glycemic control with oral anti-diabetic drugs (OADs) within 6 months of initiation of therapy, initiation of an optimal insulin regimen was the preferred choice for 492 (45.3%) of the participating physicians. Premixed insulin was preferred for initiating insulin therapy in patients with type 2 diabetes, by 676 (62.2%) of the participants [as compared to basal by 375 (34.5%) participants]. Once daily premixed insulin, intensified to twice daily was preferred as most optimal insulin regimen for initiation and subsequent intensification of insulin therapy [487 (44.8%) participants]. Most of the participants preferred adopting a multi-targeted approach for treating diabetes, hypertension, and dyslipidemia.

CONCLUSIONS

Physicians prefer treatment goals similar to those recommended in the current guidelines of the American Diabetes Association for managing their patients with diabetes. Premixed insulin is preferred for initiation and intensification of insulin therapy.

Physicians' perceptions of a national consensus guideline on insulin therapy: Data from the IMPACT study

INTRODUCTION

The effectiveness and impact of the Indian insulin guideline in clinical practice was evaluated by the Improving Management Practices and Clinical Outcomes in Type 2 Diabetes (IMPACT) Study. The study also evaluated the participating physicians' perceptions on the use of IIG versus RCP for management of diabetes.

MATERIALS AND METHOD

This 26 week multicenter, open label, randomized, prospective study aimed to evaluate effectiveness of Indian insulin guideline (IIG) versus routine clinical practice (RCP) in patients with type 2 diabetes (T2D).

RESULTS

Out of 426 physicians who completed the physicians' perception questionnaire, 189 (44.4%) felt that it was "easy" to initiate insulin in their patients using IIG. Cost of therapy (52.3%), followed by poor adherence (40.3%), and lack of motivation among physicians (40.4%) were the most important reasons cited for delay in initiation of insulin therapy. Two hundred and thirty three (54.7%) physicians felt that insulin titration was made "easy" in their patients using IIG, while 104 (24.4%) had a neutral approach. A total of 222 physicians (52.1%) felt it was "convenient" applying IIG in their practice, and 239 (67.8%) physicians felt "satisfied" with using IIG for achieving the targeted HbA1c <7%. One hundred and seventy seven (41.5%) physicians felt that there was scope for improving the IIG further by simplifying and revising the titration charts [117 (27.5%)].

CONCLUSION

Primary care physicians in India have perceived the IIG to be easy algorithm to initiate and titrate insulin therapy. These results will encourage the use and facilitate future revision of the guideline.

Baseline results indicate poor glycemic control and delay in initiation and optimization of insulin therapy: results from the improving management practices and clinical outcomes in type 2 diabetes study

INTRODUCTION

Improving management practices and clinical outcomes in type 2 diabetes (IMPACT), was a prospective, open-label, 26- week, comparative, multi-center study to compare efficacy and safety of the Indian insulin guideline (IIG) group versus routine clinical practice (RCP) group in patients with type 2 diabetes.

MATERIALS AND METHODS

A total of 20,653 patients from 885 centers across India were enrolled and treated with premixed insulin therapy as per IIG or routine care.

RESULTS

Most of the participating centers (81.7%) reported following a diabetes guideline in their practice routinely but only 20.4% targeted HbA1c <7%. Very few of the physicians (2.7%) reported that most of their patients (>75%) achieved an HbA1c <7%. Most of the physicians (39.8%) also agreed that only 10-25% of the patients agree to start insulin therapy at the first counseling. Mean duration of diabetes before initiating insulin in patients using oral anti-diabetic drugs (OADs) was 7 years, indicating a delay in initiating insulin therapy. The difference in mean daily dose of insulin at initiation vs. at 26 weeks was only 0.8 U (25.8 ± 11.3 at initiation compared to 26.6 ± 9.5, respectively, p = ns) suggesting lack of treatment optimization. Weekly titration till achieving HbA1c <7% was done in 51.1% of the patients and only 8.9% performed self-titration.

CONCLUSION

Baseline glycemic control in these patients was poor and reflects a delay in initiating insulin therapy. Data also reflect a lack of optimization of insulin doses.

Improving management practices and clinical outcomes in type 2 diabetes study: Prevalence of complications in people with type 2 diabetes in India

INTRODUCTION

Diabetes is the fourth leading cause of disease-related death and almost 80% of diabetes-related deaths occur in developing countries. Optimal glycemic control, in particular HbA1c level less than 7% with effective management of dyslipidemia and hypertension can reduce development of diabetes-related complications. Delay in initiating/or optimizing appropriate anti-diabetic therapy including insulin could be a possible cause of the increase in complications.

METHOD

Improving management practices and clinical outcomes in type 2 diabetes (IMPACT) was a prospective, open-label, 26-week, comparative, multi-center study to compare efficacy and safety of the Indian insulin guideline (IIG) group versus routine clinical practice (RCP) group in type 2 diabetes patients. A total of 20,653 subjects from 885 centers across India were enrolled.

RESULTS

A total of 4695 patients (22.7%) (IIG, 4113 [22.6%]; RCP, 582 [23.5%]) had macrovascular complications and 8640 patients (41.8%) (IIG, 7486 [41.2%]; RCP, 1154 [46.6%]) had microvascular complications. Of 4695 patients with macrovascular complications, 2850 patients (60.7%) had coronary heart disease followed by 1457 patients (31.0%) with peripheral vascular disease. Of all the microvascular complications recorded, 5627 patients (65.1%) had peripheral neuropathy followed by 3313 patients (38.3%) with retinopathy.

CONCLUSION

The rates of complications were high in patients with type 2 diabetes at the time of being initiated on insulin therapy in India.

Baseline characteristics of the IMPROVE control study population: A study to evaluate the effectiveness of a standardized healthcare professionals training program

INTRODUCTION

The IMPROVE Control Training program was designed by Indian Academy of Diabetes (IAD), and a non-intervention study was conducted to evaluate the effectiveness of this standardized healthcare professionals (HCPs) training program on achieving treatment goals in patients with diabetes mellitus and its impact on standard of care.

MATERIALS AND METHODS

This multi-center, parallel group, open-label, non-randomized, non-intervention study included patients with type 2 diabetes who had an HbA1c >9 at time of diagnosis or an HbA1c >7% even after 6 months of initiation of therapy with anti-diabetic agents (Oral anti diabetic agents (OADs) and/or insulin). The data recorded at baseline included demographic characteristics, medical history, and the treatment regimens.

RESULTS

The study included 20,493 patients with diabetes, of which 13,295 (64.9%) were men. The mean [standard deviation (SD)] duration of diabetes was 6.4 (4.2) years and 6608 (32.2%) reported complications of diabetes. Poor glycemic control [HbA1c = 9.4 (1.3), FPG (mg/dl) = 181.2 (45.7); mean (SD)] was observed. The postprandial glucose was also high [post-breakfast, lunch, and dinner values in mg/dl were 263.6 (68.5), 278.1 (69.6), and 250.2 (63.7), respectively] in these patients. Failure of OADs was the most common reason cited for initiation of insulin. Premixed insulin was rated the regimen of choice for initiating therapy by the physicians (62.2% vs. 34.5% who preferred basal insulin).

CONCLUSION

The baseline results confirm the poor glycemic control and the delayed initiation and/or inadequacy of treatment in subjects with type 2 diabetes. These results also highlight the need for early and optimal insulin-based therapy.

ANCIENT SCHWANNOMA OF THE CHEST WALL DIAGNOSED BY FINE NEEDLE ASPIRATION CYTOLOGY- A RARE CASE REPORT

Schwannomas are benign peripheral nerve sheath tumors. Ancient schwannoma is an uncommon variant of schwannoma, which is usually located in the retroperitoneum. Those located in the chest wall are extremely rare. We report a case of ancient schwannoma in a 34 yr old male who presented with left sided chest pain, found to have a mass lesion in the chest wall radiologically. CT guided fine needle aspiration cytology showed features of ancient schwannoma which was confirmed on histopathology. Cytological findings in correlation with long standing nature and well defined borders on radiological examination of the lesion will aid in the preoperative diagnosis and proper management.

SCROTAL CALCINOSIS - RARE CASE REPORTS OF TWO CASES

Scrotal calcinosis is a benign disease characterized by multiple calcified scrotal nodules. The nodules develop slowly over many years and patients usually do not seek for treatment, until they grow to large size. Histopathological examination shows deposition of basophilic amorphous material surrounded by giant cell granulomatous reaction. We report two cases of scrotal calcinosis occurring in 27 year and 45 year old males who presented with multiple scrotal swellings. Clinical diagnosis was multiple sebaceous cysts. On histopathology, excised swellings showed deposition of calcium with giant cell reaction. On regular follow up both are doing fine without any recurrence.
