Background: UJVIRA is the first DCGI approved biosimilar of trastuzumab emtansine (Kadcyla) which may offer an alternative cost-effective treatment option for HER2-positive metastatic breast cancer patients in India. This article summarizes the available clinical evidence supporting the biosimilarity of UJVIRA and Kadcyla with respect to efficacy, pharmacokinetic, safety, and immunogenicity. Methods: A phase 3, randomized, open-label, active-controlled study was conducted at 31 sites across India. A total of 168 patients were enrolled and randomized to receive either UJVIRA or Kadcyla. Of which, only first 50 patients were included in pharmacokinetic assessment. UJVIRA or Kadcyla were administered at a dose of 3.6 mg/kg by intravenous infusion every 3 weeks (21 days) for 8 cycles or until disease progression or unmanageable toxicity, whichever was earlier. The study assessed efficacy (ORR), safety, pharmacokinetics, and immunogenicity. Results: The ORR at the end of Week 24 was 37.76% in the UJVIRA and 33.33% in the Kadcyla group. The risk difference was 4.42% [-12.01, 20.85]. It met non-inferiority margin of -15%. The pharmacokinetic parameters were comparable between groups. No anti-drug antibody was detected in any of the treatment groups. The overall safety profile in terms of TEAEs and laboratory abnormalities was also comparable between the treatment groups. Conclusion: Results demonstrated biosimilarity between UJVIRA and Kadcyla in terms of efficacy, safety, pharmacokinetics, and immunogenicity. Therefore, UJVIRA could prove to be a cost-effective treatment alternative for HER2-positive metastatic breast cancer patients in India.

The study aimed to determine clinical presentation, contributing factors, medical and surgical management, and outcome of patients with coronavirus disease 2019 (COVID-19)-associated mucormycosis (CAM). A cross-sectional, single-center study was conducted on patients receiving multidisciplinary treatment for mucormycosis following the second wave of COVID-19 pandemic from April to June 2021 in India. Clinicoepidemiological factors were analyzed, 30-day overall survival and disease-specific survival were determined, and t-test was used to determine the statistical significance. A total of 215 patients were included in the study, the cases were stratified into sino-nasal 95 (44.2%), sino-naso-orbital 32 (14.9%), sino-naso-palatal 55 (25.6%), sino-naso-cerebral 12 (5.6%), sino-naso-orbito-cerebral 16 (7.4%), and sino-naso-orbito-palato-cerebral 5 (2.3%) based on their presentation. A multidisciplinary team treated patients by surgical wound debridement and medical therapy with broad-spectrum antibiotics and amphotericin B. Across all disease stages, cumulative 30-day disease-specific survival is 94% (p

The era of information and communication technologies has created many opportunities in every aspect. The field that has been benefitted the most from these recent developments in the financial and business sector. The scope and speed of evolution in technology, customer perception, and wide acceptance indicate that these technologies and disruptions will transform the finance and banking sector as we know it, providing both opportunities and challenges to financial institutions. Systems that have traditionally been used for savings, investments are not well suited given the scale and agility required for the digital age. Keeping in mind this array, financial institutions are responding with new digitization and innovation initiatives, using analytics, cloud technologies, and other new alternatives to respond to customer expectations. In a country like India, with a large economy and a despotic regime, the country shows decent economic growth even after having a complex system of arbitrary rules and regulations. Amidst all the growth, there is a huge scope of transforming the investment and lending patterns, with the help of technologies becoming more customer-centric and efficient. So, the technologies like blockchain are looking to drive innovation across various industries in India. In the era of blockchain, cryptocurrencies are the main part of it. They are said to be the most disruptive technologies in this area. This paper is an attempt to find the future of digital currency in India from the international experience.

Background: Prevalence of diabetes mellitus and impaired fasting glucose are reported to be highly variable among rural and urban population in India. Objective: To estimate the prevalence of diabetes mellitus among adult slum people. Methods: A cross sectional analytical study was carried in the field practice of tertiary health care center on adult slum dwellers on sample of 2919 by door to door survey provided they fulfill the inclusion criteria. 18 years and above both the gender was included in the study. Surveyed population is divided into three groups on the basis of Random Capillary Blood Glucose Level. (Group I -79-160mg/dl, Group II- 161-200mg/dl, Group III- >200mg/dl). Result: The prevalence of Diabetes mellitus is 9.28%. Out of 271, the maximum numbers of confirmed diabetic cases were falling in the age group of 51-60 years. The minimum number observed in the 3rd decades. A total 149 (28.27%) were male and 122 (27.3%) were female are diabetics. and non-diabetics. Conclusion: Individual with confirmed diagnosis is at the risk of musculoskeletal symptoms.

Oral cancers are amongst the most common cancers in the Indian subcontinent; in India alone, an estimated 1.2 lakh new patients were diagnosed with it. Reconstruction with free flaps slowly gained popularity over time to become the standard for care for treating large head and neck defects. Flap selection is a complex process; more specifically, the preoperative conditions of patients, the extent of the disease, and the resources available are critical considerations to consider when selecting the best reconstructive technique. It is very well established that certain parts of India, especially the tribal area of Central and southern India, have high prevalence of sickle cell trait (SCT) and sickle cell disease compared to the rest of the country. The sickle cell trait poses a potential increase in morbidity in the perioperative care due to surgical stress. Unfortunately, there are no published articles on the management of a free flap in a case of SCT. Here, in this article, we investigate the issues encountered during the perioperative care in a patient who undergone oral cavity composite resection with free fibula reconstruction. SCT screening must be undertaken mainly to identify, mitigate, and manage the adverse events in the perioperative period. The screening test is very inexpensive and has good sensitivity to detect the heterozygous and homozygous disease. We would recommend screening of all the patients hailing from high-risk endemic areas. The free flap in a case of sickle cell trait is not a contraindication, but a surgeon must understand the nuances in the management of complications in such case. Screening for sickle cell trait followed by perioperative blood transfusions, anticoagulation seems beneficial in a patient undergoing free flaps with sickle cell trait.

Rituximab biosimilars are a cornerstone of treatment of advanced-stage follicular lymphoma (FL). This double-blind, parallel-group, phase 3 trial randomized (1:1) adults (≥18 years) with stage III to IV indolent B-cell lymphoma, including grades 1 to 3a FL, to receive CT-P10 or rituximab (375 mg/m2 IV), with cyclophosphamide, vincristine, and prednisone, every 3 weeks for 8 cycles (induction period). Patients achieving complete response (CR), unconfirmed CR, or partial response (PR) received CT-P10 or rituximab maintenance for 2 years (375 mg/m2, every 8 weeks). Primary end points were previously reported, proving noninferiority of efficacy and pharmacokinetic equivalence of CT-P10 to rituximab. Secondary end points included overall response rate (PR+CR) during the induction period per 2007 International Working Group (IWG) criteria, survival analyses, and overall safety. Between 28 July 2014 and 29 December 2015, 140 patients were randomized (70 per group). Median follow-up was 39.9 months (interquartile range, 36.7-43.5). Per 1999 IWG criteria, 4-year Kaplan-Meier estimates (95% confidence interval [CI]) for CT-P10 and rituximab were 61% (47% to 73%) and 55% (36% to 70%) for progression-free survival (hazard ratio, 1.33 [95% CI, 0.67-2.63]; P=.409), respectively, and 88% (77% to 94%) and 93% (83% to 97%) for overall survival (5.29 [0.84-33.53]; P=.077). Overall, 90% (CT-P10) and 86% (rituximab) of patients experienced treatment-emergent adverse events. Long-term safety profiles were similar between groups. Findings confirm favorable outcomes for CT-P10–treated patients with advanced-stage FL and demonstrate comparable long-term efficacy and overall safety between CT-P10 and rituximab. This trial was registered at www.clinicaltrials.gov as #NCT02162771.

Background Hepatocellular carcinoma (HCC) is a highly malignant tumor, causing both intrahepatic and extrahepatic metastases. The extrahepatic metastasis occurs in one-third of patients with HCC and it is associated with a poor prognosis. The most common sites of extrahepatic metastasis are lung, regional lymph nodes, bone, adrenal glands, and peritoneum/omentum. Detection of such extrahepatic metastasis plays a vital role in the staging and treatment planning of HCC. Case presentation A 60-year-old man was presented to our centre with loss of apetite, generalised weakness, and weight loss. Abdominal examination revealed a firm lump in the right hypochondrium. CT findings revealed a large well-defined hypodense mass in almost entire right lobe of the liver. A well-defined oval, heterogeneously enhancing soft tissue mass lesions were also noted in both adrenal glands and psoas muscles. For histopathological diagnosis, percutaneous ultrasound-guided truecut biopsy was done from right lobe liver mass confirming well differentiated HCC. Conclusions In the present case report, we present an extremely rare and unique case of HCC with disseminated skeletal muscle metastasis with concomitant bilateral axillary lymph node metastasis. It is crucial for radiologists to detect such extrahepatic sites of metastasis initially at the time of diagnosis for accurate staging and treatment planning for a better prognosis.

To analyse and identify possible outcomes of elective cancer surgeries performed at a tertiary cancer centre during COVID19 pandemic. This is a retrospective study including patients that underwent surgery at HCG Manavata cancer centre, Nashik, Maharashtra, India, from 15 March 2020 to 15 June 2020. Among the 458 patients that underwent elective surgeries, 54% were male and 46% were female, with a median age of 50.57 years. The most common sites of cancer distribution were head and neck (24.67%), colorectal (11.57%), gynaecological (11.35%), and breast (10.26%). Of the included patients, 92% were of American Society of Anaesthesiologists (ASA) II with comorbidities such as hypertension, and 64% underwent major surgeries with a mortality rate of 1.52% (n = 7). Average duration of surgery and hospital stay was observed to be 168.43 min and 4.4 days, respectively. Post-operatively, 7 patients were tested COVID positive and their recovery was uneventful. Despite the difficulty that set in because of COVID19 pandemic, it was proven from our study that elective cancer care surgeries can be successfully performed by following all the set guidelines.

The COVID 19 pandemic continues its havoc over the last six months in India. The present study of the initial phase of illnesses in mild to moderate cases of SARS-COVID is the rampant community transmission. This observational and cross-sectional study aimed to analyse and correlate the socioeconomic and demographic parameters with clinical and psychosocial presentations of the COVID disease through a questionnaire-based interaction Mild and moderate COVID positive patients with stable hemodynamic were enrolled for the study. The findings revealed that of the 179 patients, the majority of patients were adults below 60 years of age group, followed by the older age group above 60. Males had a slightly higher preponderance than females. The majority of people in their families were medium to big and overcrowded, lacked social distance and poor hygiene practises were partially attributable to bad social economic conditions. Most of the patients originated from the red area, i.e. high-risk zone, as well as the high level of transmission of COVID illnesses to human beings. The majority of patients were in the poor and lower middle classes (Kuppuswamy modified scale).Most of the occupations of COVID patients involved the lower strata labour jobs. Fifty percent of patients had no symptoms at onset and remained asymptomatic throughout the illness. There were many issues and insecurities in most patients relating to the current illness, future well-being of families, job and financial concerns that warrant strategies to be implemented during and in post COVID era.

Primary liposarcoma at vallecula is an extremely rare tumor in hypopharyngeal region. Vallecular liposarcoma shares both clinical and imaging features with other common lesions at this site such as benign lipoma, mucus retention cysts, fibrovascular/ inflammatory polyp and epithelial malignancies extending from adjacent anatomical structures. The two closest mimickers in laryngeal region, atypial lipoma and well differentiated liposarcoma are very difficult to differentiate on laryngoscopic examination and radiological investigations. Dedifferentiation; a poor prognostic histological feature can rarely occur after multiple recurrences but liposarcoma with de novo de-differentiation in larynx is very rare. Herein, we describe a case of liposarcoma with de novo de-differentiation originating from vallecula in a 66 years old male with review of literatures.

Parathyroid glands, minute endocrine glands, located in posterior aspect of thyroid glands secrete parathormone which plays an important role in maintaining calcium homeostasis in the body. The superior and inferior parathyroid glands originate from the 4th and 3rd branchial pouches respectively and migrate to occupy their normal positions in relation to the thyroid gland.1 Hyperparathyroidism is defined as hyper functioning of parathyroid gland and can be primary, secondary or tertiary. Primary hyperparathyroidism is due to parathyroid gland proliferative disorders which include parathyroid adenoma, parathyroid hyperplasia, parathyroid carcinoma or in association with other conditions in MEN syndrome. In more than 90 % patients, primary hyperparathyroidism is caused by a single parathyroid adenoma. Very rarely double parathyroid adenomas are seen. Secondary Hyperparathyroidism is caused in response to any chronic hypocalcaemic conditions like renal failure, gastrointestinal malabsorption, dietary rickets & drugs, like phenytoin, phenobarbital & laxative. Prolonged secondary hyperparathyroidism leads to tertiary hyperparathyroidism due to autonomous secretion. The clinical presentation of hyperparathyroidism is classically described as kidney stones, abdominal groans, painful bones, psychic moans, and fatigue overtones. In the initial course of the disease, the patients present with vague symptoms of fatigue, muscle and joint pain, frequent urination, nausea, constipation, and decreased appetite. If high index of suspicion is maintained, they can be conveniently diagnosed by routine blood tests which show increased calcium levels. However, in India still majority of people are diagnosed when they present with palpable neck mass, skeletal manifestations or deranged renal function. We hereby present 5 cases of parathyroid adenoma managed at our centre over a period of 2 years. P

Dealing with disaster could be a human process that requires public support for coming up with. It needs to be property within the lightweight of challenges expose by non-renewable resource utilization, global climate change, growth and imbalances of wealth. Emergency, not only includes nephrotoxic spills and industrial explosions however conjointly the floods, storms and earthquakes. Disaster management essentially deals with the management of resources and knowledge towards a disastrous event and is measured by however efficiently, effectively and seamlessly one coordinates these resources. the power to effectively traumatize disasters has become a challenge to fashionable technology. Disasters maybe divided into fast disasters and continuing disasters. Earthquakes, floods and tsunamis are thought of as fast onset disasters whereas civil wars, droughts, famines and epidemics are the continued or future disasters.

In India, newborn hearing screening programs have been implemented as a part of research studies since early 1970s. Amongst the previously reported programs most are from the southern region and very few are from the west and the northern region of the country. There is a lack of evidence of such program in other region of the country. 1. To study the outcome, experience, and challenges faced during the implementation of the universal newborn hearing screening program in a medical college set up of Raipur, Chhattisgarh. 2. To determine the prevalence of hearing impairment with a two tier screening protocol with Otoacoustic emission and Auditory Brainstem Response. The Prospective Non randomised study was carried out between December 2017 and December 2019. A total of 1200 neonates delivered at the medical college, Raipur were screened using the two tier screening protocol. In our study, the prevalence of hearing loss was 2 per 1000 live births for bilateral hearing loss and 1 per 1000 live births for unilateral hearing loss. Implementing universal newborn screening in a vast country like India is a challenging task because of a high birth rate, diverse socio-economic and cultural background with limited resources. Though several hospitals and clinics have implemented the UNHS program, yet there is a dearth of literature regarding the program outcome, success, challenges, and lessons learnt. Therefore best practices of such evolved programs should be in public domain.

The aim of the present study was to evaluate the prognostic value of the inflammatory response biomarkers and their impact on survival outcomes in the patients with sarcomatoid carcinoma (SC) of oral cavity, a rare variant of squamous cell carcinoma (SqC). Seventeen patients diagnosed with SC of oral cavity without metastases treated between Jan 2017 to June 2020 were identified and included in the present study. Pre- and post-operative inflammatory biomarkers and other prognostic markers were evaluated and their impact on disease-free survival (DFS) and overall survival (OS) was studied. Seventeen patients (16 males and one female) were included in the present study with a median age of 42 years (IQR: 26–76 years). With the median follow-up of 15 months, nine of 17 patients had developed recurrence and were succumbed to either locoregional recurrence or distant progression. One-year Kaplan–Meier estimates of DFS and OS were 57% and 58.3% respectively. On univariate analysis, baseline NLR, PLR, and pathological bone/skin involvement were identified to be significant prognostic factors affecting the patient’s DFS and OS. On multi-variate analysis, baseline NLR > 3 and pathological bone or skin involvement by tumour were emerged as some independent significant predictors. For the first time, the predictive role of inflammatory markers is studied and proven significant affecting patients’ survival outcomes. Hence, these inflammatory biomarkers may be considered for routine clinical use as reliable and low-cost prognostic markers to tailor the management of SC of oral cavity.

BACKGROUND: Immune thrombocytopenia (ITP) is an autoimmune hemorrhagic disorder, where autoreactive T-cells and/or autoantibodies destroy platelets and megakaryocytes in the spleen and bone marrow, respectively. To the best of our knowledge, this is the largest cohort of cases wherein patients were treated with novel combination therapy of a corticosteroid with an adjunct immunosuppressive agent for the treatment of ITP in adults. In cohort of 23 patients, 11 patients have no response and 12 patients have shown partial to complete response (CR) to the treatment. The primary aim of the present study was to explore the safety and efficacy of combination therapy in chronic ITP along by evaluating the toxicity associated with prolonged steroid exposure. The secondary aim was to compare the cost benefit with other available modalities for chronic ITP treatment. MATERIALS AND METHODS: A retrospective observational study was carried out by collecting data from electronic medical records of all the ITP patients treated at HCG Manavata Cancer Centre, India, between May 1, 2019, and April 30, 2020. Inclusion and exclusion criteria were strictly followed for data collection and analysis. RESULTS: Twelve (52%) of the 23 patients have shown response to the combinational therapy; 5 (22%) patients achieved a partial response (PR) and 7 (30%) achieved a CR. In the PR group, 3 patients developed thrombocytopenia and 1 switched to thrombopoietin receptor agonists, whereas in 7 CR patients, 6 have maintained it until end and 1 patient was switched to maintenance therapy. CONCLUSION: A combination of immunosuppressant and corticosteroid on ITP patients appeared to be effective, tolerable, with minimal adverse side effects, and an economical alternative. Therefore, this novel combination therapy may be an excellent alternative for the treatment of patients with ITP in clinical settings.

Background To evaluate patterns of blood pressure (BP) changes in patients with head and neck cancer (HNC) receiving radiation (RT)/chemo-radiation (CRT) METHODS: This study included data collection, compilation, and analysis of 451 consecutive HNC patients who underwent RT/CRT. Results Out of 451 patients, 376 (82%) were male and 75 (18%) were female with a median age of 52 years. Patients receiving 3DCRT experienced greater fall in BP, including for SBP and MAP, compared to those receiving IMRT-IGRT. Female patients experienced greater fall in diastolic BP as compared to male patients (p: 0.03). At the end of treatment, we observed a significant association between a fall in systolic BP (decrease by 10% of baseline) and weight loss of more than 10% of baseline weight (p: 0.03). Conclusion Fall in BP during RT/CRT is significantly affected by treatment technique and sex and is strongly associated with significant weight loss.

Periampullary adenocarcinomas are rare neoplasm that originates from the pancreatic head, the ampulla of vater, the distal bile duct or the duodenum. Surgical resection followed by adjuvant therapy is considered as the standard of care treatment for these carcinomas. Despite several advances in diagnostics and therapeutics, only 5% of these patients have an overall survival of five years or more. Currently, there is a dearth of viable therapeutic targets for this disease. The role of HER2 in cancer biology has been studied extensively in several tumour subtypes, and HER2 based targeted therapies have shown to have therapeutic benefits on different cancers. In this case report, we present a case of HER2 positive distal common bile duct carcinoma - a subtype of periampullary carcinoma with multiple relapses where multi-analyte testing with Encyclopedic Tumor Analysis (ETA) (Exacta®) identified amplification and over expression of HER2 gene which was used as a potential target to treat the patient with trastuzumab. Synchronous in vitro chemosensitivity profiling on Circulating Tumor Asscociated Cells (C-TACs) isolated from blood aided us to design the personalized chemotherapeutic regimen with cyclophosphamide and methotrexate. The combination of trastuzumab with cyclophosphamide and methotrexate yielded excellent treatment response with the patient remaining in complete response till the last follow-up. Our study suggests HER2 directed therapy as a potent pathway for treatment in the subset of HER-2 amplified distal common bile duct carcinomas.

High-resolution neutron imaging is difficult, due to the low-light output of neutron scintillators, and the spread of light within common neutron-sensitive scintillators as well as the spread of intermediate particles occurring during the detection process. To address this issue, we have developed a high-resolution scintillator for neutron imaging by combining enriched 10B with the well-known CsI:Tl scintillator films. CsI:Tl has excellent properties for X-ray imaging applications, due to a high light yield of 60 000 photons/MeV, and high spatial resolution, which derives from its microcolumnar structure, which channels scintillation light to the photodetector. To enable CsI:Tl to detect neutrons, 10B (96% enriched) was deposited by electron beam directly onto the CsI:Tl film, making a layered scintillator structure in which the alphas produced by the neutron interaction with 10B are detected in the CsI:Tl. The 10B layer was approximately $3~\mu \text{m}$ thick, while the thickness of the CsI:Tl film was $11~\mu \text{m}$ . These novel layered scintillators were integrated into the high-resolution neutron imaging detector [“Paul Scherer Institute (PSI) Neutron Microscope”] at the Pulse OverLap DIffractometer (POLDI) beamline at the PSI. With our 10B/CsI:Tl scintillator, we were able to achieve a spatial resolution down to $9~\mu \text{m}$ . To demonstrate the effectiveness of the layered scintillator, we present results obtained by thermal neutron imaging as well as high-resolution neutron-computed tomography. Finally, we believe there is considerable scope for future optimization of the performance of this system.

A 17-year-old female patient who came to the Otorhinolaryngology and Head and Neck Surgery department with chief complaints of bilateral ear discharge and hearing loss Since 1 year. She was diagnosed as a case of Turner syndrome based on Cardic-CT, USG-pelvis, CT-MRI Pelvis with Abdomen Screening, and Chromosomal analysis revealed 45, X pattern in all the metaphases. In the Preoperative investigations, Pure tone audiometry shows left ear (83dB HL) severe mixed hearing loss and right ear has (63dB HL) with moderately severe mixed hearing loss and in HRCT-Temporal bone features suggesting the most possibility of bilateral Cholesteatoma. Pre operatively Left ear soft tissue Histopathological examination was showed Cholesteatoma with active inflammation. Tympanomastoidectomy was planned for left ear and performed the procedure was Canal wall down mastoidectomy with type 3 tympanoplasty. Intraoperatively findings were thick KORNER'S septum, full of pale non bleeding granulations in antrum, aditus and around ossicles were observed in the middle ear. After surgery, Postoperative histopathology report showed necrotizing granulomatous inflammation consistent with tuberculosis (special stain for AFB is positive). In conclusion primarily this is a very rare case of Tuberculous Otitis Media. In such type of cases there are more chances of misdiagnosing by many clinicians as Tuberculosis was rarely occur in the ear and most of the findings are also absent as seen in our case. It is difficult to identify and diagnose the case at initial stages of a disease. In such type of cases outcome of patients is poor due to delayed diagnosis.

Scintillation detectors exhibiting high spatial resolution and fast timing capabilities are of vital importance for synchrotron sources. These detectors may be exposed to a variety of X-ray energies (up to 140 keV) and used in high frame rate applications. Here, we describe the advances in the development of thin-film LuI3:Ce scintillators for higher energy X-ray imaging, with fast timing and high spatial resolution. When grown in a single crystalline form, these scintillators are bright, producing 115 000 photons/MeV. However, to achieve high spatial resolution, these scintillators are grown in thin-film form with a microcolumnar structure, controllable to column diameters of $30~\mu \text{m}$ . Thus, a much thicker scintillator layer ( $10~\mu \text{m}$ –3 mm or higher) may be grown, providing superior X-ray absorption while achieving high resolutions of $50~\mu \text{m}$ or better, at the cost of reduced light yield. To study the timing characteristics of the scintillator, time-resolved X-ray excited optical luminescence (TR-XEOL) was performed on two different sets of three samples of LuI3 at the 1-BM beamline of the Advanced Photon Source at Argonne National Laboratory. Besides, we report timing measurements obtained using a photomultiplier tube (PMT) and oscilloscope at Radiation Monitoring Devices (RMD) Inc. Using the TR-XEOL, we determined the decay constants of LuI3 as a function of Ce doping, recording a fast decay component as low as 3.6 ns (39%), one of the fastest values recorded in inorganic scintillators. This fast decay opens up numerous novel applications, where ultrahigh frame rates are important using synchrotron X-rays. This article will discuss fabrication, characterization, and potential applications for this novel scintillator.

Fiber-reinforced composites have become the material of choice for aerospace structures because of their favorable strength-to-weight ratio. Given the increasing amounts of counterfeit composite parts showing up in the complex aerospace supply chain, it is absolutely vital to track a composite part throughout its lifecycle-from production to usage and to disposal. Existing barcoding methods are invasive, affect the structural properties of composites, and/or are vulnerable to tampering. We describe a universal method to store information in fiber-reinforced composites based on solid-state in situ reduction leading to embedded nanoparticles with controlled morphologies. This simple, cost-effective, mild, surfactant-free, and one-step protocol for the fabrication of embedded platinum nanostructures leads to morphology-based barcodes for polymeric composites. We also describe a coding methodology wherein a 1 × 1 cm code can represent 3.4 billion parts to 95 trillion parts, depending on the resolution required along with access to morphology-based chemical encryption systems.

Background Radiation therapy (RT) has remained the mainstay treatment approach for head and neck cancers. Weight loss due to tumor or tumor-related factors remains a major health issue among head and neck cancer patients. Methods A total of 357 patients were identified for the study. Possible weight-loss predictors were determined in the patients undergoing RT based on the patient demographics, tumor site, and treatment characteristics. Results The mean age of patients was 52 years, whereas the median age was 51 years (range, 18-87). Two hundred and thirteen (66%) patients had oral cavity cancers, 43 (14%) had oropharyngeal cancer, 26 (8%) had hypopharyngeal cancer, 13 (6%) had larynx cancer, and 19 (6%) had other site involvement. A total of 192 patients received 3-dimensional conformal radiation therapy (3DCRT), whereas 127 patients received intensity modulated radiation therapy-image guided radiation therapy (IMRT-IGRT), 212 (66%) received concurrent chemotherapy, and 107 (34%) patients did not receive concurrent chemotherapy. A total of 127 (40%) of the patients gained weight during the first week of RT; on the other hand, maximum weight loss among patients was occurred during the third and fourth weeks of RT. Conclusion Analysis by logistic regression determined there is significant weight loss (>10%) in patients receiving radical RT as compared with adjuvant RT. Better outcomes were observed in patients receiving RT by IMRT-IGRT technique as compared with 3DCRT technique.

Objective The aim of the study was to analyze the prevalence of molecular subtypes of all breast cancer patients treated at tertiary cancer centre in West India in 12 years. Materials and methods A retrospective observational study carried out in Tertiary Cancer Care Centre in Western India. Electronic medical records of all breast cancer patients were retrieved from the hospital database between March 2007 to March 2019. Patient's characteristic, histological features and molecular subtypes were collected and analyzed. Results A total of 2062 women fulfilled the criteria for this study and were analyzed. The median age of study population was 51 years (range 22-100 years). Among these, 1357 (65.8%) were of ≤55 years and 705 (34.2%) were over 55 years. The overall incidence of Hormonal Receptor-positive patients (either estrogen-receptor (ER) or progesterone-receptor (PR) or both) was 1162 (56.4%). The Mean tumor size was 3.8cm (range 0-18cm). The most common histology was IDC (96%). Axillary nodes were positive in 62.5%. Luminal type A was positive in 762 (37%) patients while Luminal type B was present in 157 (7.6%) patients. Basal-like subtype was observed in 537 (26%) patients while HER2 rich subtype was seen in 229 (11.1%). The incidence of Luminal A subtype increased with age. The highest observed among patients (72%) aged 70 years or more. Incidence of Basal like subtype was highest in patients less than 30 years (52%). Conclusion Luminal-like disease is the most common molecular subtype in India. Identification of Basal like breast cancer, a highly aggressive, biologically and clinically distinct subtype different than its non-basal variant, is important for treatment planning and target therapy.

Neuroauditory-toxicity should always be borne in mind prior to treatment of severe conditions like cerebral-malaria and due attention should be paid to auditory monitoring. Artemisinin-based combination therapy is the best available treatment for cerebral malaria however its attribution to hearing loss remains undetermined. This report manifests ototoxic effect of artemisinin.

Conclusion The results of the study showed that the disease was associated with the male gender, young and middle age, low socioeconomic status, rural background, pond bathing and O+ blood group.

Sinonasal mucormycosis is a deadly fungal illness that primarily affects diabetics who are uncontrolled. Numerous cranial nerves can be involved; however, facial nerve palsy has only been observed in a few cases. The main objective of this research is to highlight facial nerve involvement as a clinical sign of sinonasal mucormycosis. Nasal stuffiness, headaches, eye pain, orbital edema, ophthalmoplegia, and vision loss are common symptoms in these mucormycosis patients. The study was done in the Department of Otolaryngology & Head and Neck Surgery, All India Institute of Medical Sciences (AIIMS), Raipur, India. Nevertheless, 17 patients with facial nerve palsy (lower motor nerve palsy) and sinonasal mucormycosis arrived at our department. All patients were diabetic, and a majority of patients got Schirmer's test positive with severe stage. In the case of mucormycosis, facial nerve palsy is an unusual but noteworthy symptom. This could be misinterpreted as a cerebrovascular accident (CVA), causing the therapy to be delayed. This is critical as early identification, surgical debridement, and adequate therapy of the underlying metabolic imbalance, as well as amphotericin B, are critical for a successful treatment outcome in mucormycosis.

This paper discusses the reasons for emergence of predatory publications in India, engendered by mandates of higher educational institutions: that require stipulated number of research publications for employment and promotions. Predatory journals have eclipsed the merits of open access publishing, compromised ethical practices, and left the research community groping for benchmarks of research integrity and publication ethics. To fight back the menace of predatory publications, University Grants Commission, India has established “Consortium for Academic Research and Ethics” (UGC-CARE) in 2018 to promote and benchmark research integrity and publication ethics among the Indian academia. The present paper discusses the UGC-CARE initiative, its structure, objectives and specifically, “UGC-CARE Reference List of Quality Journals” (UGC-CARE list) and finally, the challenges it faces.

The extraction of scintillation light from an inorganic scintillator is one of the major bottlenecks in time-of-flight positron emission tomography (ToF-PET) because it directly affects the energy and time resolution of the gamma detector. To increase the light extraction efficiency, we use photonic crystal slabs (PCS), defined as thin dielectric layers structured with a 2-D, or 3-D, periodic pattern. A higher light output, combined with a reduction of the average path length traversed by the photons in the crystal before extraction, leads to a more precise evaluation of the particle time detection. This also implies a better coincidence time resolution (CTR). These improvements translate to ToF-PET reconstructed images with a higher signal-to-noise ratio and lead to more accurate diagnoses, faster exams, and possibly a reduced patient radiation dose. In this paper, we present the results obtained using lutetium-yttrium oxyorthosilicate, Lu2(1-x)Y2xSiO5 samples patterned with nanoimprinted PCS. Comparative light yield (LY) measurements show an improvement of a factor 1.68 for a naked configuration, whereas CTR goes from 535 to 315 ps.

Permanent Magnet Synchronous Motors (PMSM) are known to be preferred over other motors in electric vehicle (EV) application. However, due to over-dependence of expensive rare-earth magnets in these motors, lookout for alternate motors is on the anvil. In this paper, an optimized rotor design of Synchronous Reluctance Motor (SynRM) that is devoid of rare-earth materials is proposed in order to demonstrate its suitability in the EV category. Firstly, an analytical design method to determine the dimension of the stator and rotor structure of the SynRM is introduced. Without altering the stator design, an optimized design of rotor structure using the unit-less variables is proposed in this paper with the dual aim of maximizing the electromagnetic torque of the SynRM and minimizing torque ripple in it. Finite element analysis (FEA) is used to verify the analytical design and optimization of the rotor structure. The results of the SynRM design and optimization are presented to showcase the effectiveness of the envisaged design methodology.

The report evaluates the effect of coronavirus disease (COVID-19) pandemic on breast cancer treatment and management at a single-surgeon cancer care unit in one of the hotspots of COVID-19 in India. In response to the pandemic, the adjustments were made in the clinical practice to accommodate social distancing. Patient consultations were done over phone call or in-clinic visit with prior appointment to reduce the risk of exposure to COVID-19. Total number of patients that were treated at the clinic and the essential surgeries performed during the pandemic phases are summarized in the report. The methodology adopted here for care and management of the cancer patients can serve as a guiding principle for cancer care units in the country.

BackgroundPrecise prediction of residual tumour size following neoadjuvant systemic therapy for breast cancer is crucial in assessing response and surgical decision making. Our study is aimed at assessing the performance of conventional imaging modalities like ultrasound and mammography in predicting the residual tumour size after neoadjuvant systemic therapy and in evaluating the impact of imaging on the surgical outcomes.MethodsWe retrospectively compared the tumour size measured by ultrasonography and mammography and the residual tumour size on final histopathology in 109 patients. Concordance was defined as a size difference within 25% of the histopathology size. We also looked at the distribution of concordance between different T status and molecular subtypes, accuracy of USG in predicting pathological complete response and axillary lymph nodal metastasis and also surgical outcomes in the discordant cases.ResultsThe concordance rates of mammography and ultrasonography were 68.2% and 52.3% respectively without statistically significant difference between the two modalities (p = 0.081). Combination of both the modalities had a concordance rate of 57.8%. Ultrasonography had accuracy of 81.7% for predicting pathological complete response and 79.8% for predicting axillary nodal metastasis. We did not identify any influence of histologic subtype on the associations between preoperative measurements and pathology size or the accuracy for detecting pathological complete response (p values 0.43 and 0.46 respectively). In 12 cases, the radiology-pathology discordance could have led to large excision volume surgeries. In the overall cohort, recurrence free survival and overall survival rates at median follow up of 19.1 month were 87.2% and 95.4% respectively.ConclusionsUltrasound and mammography showed moderate concordance with pathology for estimation of the residual tumour size without any significant difference in the performance between the two. Despite the moderate concordance, surgical outcomes were fairly well managed in the discordant cases with the oncoplastic surgical techniques. Our study highlights the usefulness of the cheaper and widely available conventional imaging modalities in the developing countries where the cost of treatment is to be contained.

Tension pneumatocele is a very rare but potentially fatal complication of transsphenoidal surgery that can result from an influx of air into the intracranial cavity through the cerebrospinal fluid fistula. Although transsphenoidal surgeries for pituitary adenomas are very commonly performed procedures, this complication is extremely rare. We report a case of tension pneumatocele after transsphenoidal resection of a pituitary macroadenoma. After a second endoscopic transsphenoidal procedure to remove the air and repair of the sella floor, visual acuity recovered dramatically. Tension pneumatocele is an uncommon but potentially lethal complication of transsphenoidal pituitary surgery, which can present anytime, even after years postoperatively. It is important for all skull base surgeons to be aware of this condition so that prompt treatment can be instituted.

Sarcomatoid squamous cell carcinomas are extremely rare, high grade, aggressive variant of penile cancers. Sarcomatoid carcinoma are biphasic neoplasms with a combination of both sarcomatoid components and carcinomatous elements. These neoplasms are very rare in the urogenital system. We report a 53-year-old male presented with an ulcerated lesion on the glans penis. The rarity of this case reiterates the importance of thorough morphological and histological examination along with immunohistochemistry in diagnosing, staging, treatment and follow up of patients.

PURPOSE We sought to compare the pharmacokinetics (PKs) of DRL-rituximab (DRL_RI; potential biosimilar) and innovator rituximab MabThera (Roche, Grenzach-Wyhlen, Germany; reference medicinal product [RMP]) in patients with diffuse large B-cell lymphoma (DLBCL). Efficacy, pharmacodynamics (PDs), safety, and immunogenicity were also compared. PATIENTS AND METHODS We conducted a double-blind, parallel-group study in patients with untreated DLBCL who were eligible to receive cyclophosphamide, doxorubicin, vincristine, and prednisone (CHOP) therapy. Patients were randomly assigned at a one-to-one ratio to receive DRL_RI or RMP for six 21-day cycles of rituximab plus CHOP, with 18 months of follow-up after day 1, cycle 6 (C6). Primary end point was C1 PKs, measured as area under the plasma concentration–time curve from day 0 to 21 (AUC0-21 days) and maximum plasma concentration (Cmax). Equivalence was defined as 90% CIs for the DRL_RI/RMP geometric mean ratios (GMRs) within 80% and 125%. Secondary end points included efficacy noninferiority measured by objective response rate (ORR) at C6 and event-free survival and overall survival at 87 weeks, PK equivalence at C6 and PD equivalence (rate of B-cell depletion and repletion), safety, and immunogenicity. The trial was stopped after sufficient patients for primary end point evaluation were enrolled. Secondary end points are reported as observed. RESULTS A total of 151 patients were randomly assigned (DRL_RI, n = 76; RMP, n = 75). DRL_RI/RMP GMRs for AUC0-21 days and Cmax in C1 were 99.77 (90% CI, 87.60 to 113.63) and 96.19 (90% CI, 88.65 to 104.38), respectively. ORR at C6 for DRL_RI and RMP were 82.0% and 84.8%, respectively. Rates of B-cell depletion/repletion, immunogenicity, and adverse events were comparable in both groups. CONCLUSION DRL_RI and RMP had equivalent PKs, with comparable efficacy, PDs, safety, and immunogenicity.

Purpose:To determine the frequency, factors and reasons of patient non-adherence to radiotherapy (RT) in a tertiary cancer centre.Background:Inadvertent treatment interruptions often lead to prolongation of planned treatment time. In the case of RT with a curative intent, prolongation of planned treatment has been associated with inferior clinical outcomes. Delay or prolongation of treatment is associated with a relative risk of local recurrence by up to 2% per day for specific malignancies. Thus, it is critical to understand key factors that influence non-adherence to RT.Methods and Materials:A retrospective observation audit was conducted comprising patients treated with radical, adjuvant or palliative RT at our centre from January 2018 to December 2018. Non-adherence was defined as premature permanent termination of planned treatment by the patient without recommendation or consultation from the treating clinician. All data were collected and analysed (retrospectively) with the help of Statistical Package for the Social Sciences (SPSS) version 22.Results:A total of 1,548 patients were included in the study of which 105 (6·7%) were non-adherent to planned RT. Of the total 105 patients, 44 (42%) were elderly (60 years and above). Treatment non-adherence was predominant in males (male:female = 1·85:1). More than 90% of non-adherent patients had stage III and IV cancer. A total of 77 patients (74%) out of 105 were more than 50 km away from our centre. A total of 66 (63%) out of 105 patients had completed more than 2 weeks of radiation (40% of planned RT) and then defaulted for radiation due to acute toxicities.Conclusion:Treatment adherence is a major factor in determining successful outcomes among cancer patients treated with RT. This study reveals several factors that contribute to non-adherence to treatment.

In this paper, an “embedded chip” packaging platform using POL-kW packaging for use with High Power LED devices is presented. Prototype samples have been fabricated and tested. The authors will describe thermal modeling analysis as well as experimental results from the prototype samples. A thermal simulation model has been developed to look at the thermal properties and attributes of the POL-kW LED structure and will be compared to conventional AlN and IMS based LED packages. The process flow and fabrication details of a POL-kW LED package will be summarized to provide a better understanding of the technical and performance advantages. Initial results have shown that the presence of POL vias directly connected to the LED chip reduce the thermal path and, thereby, the thermal resistance of the package. Furthermore, the POL-kw LED package offers a thinner profile and smaller form factors which allows higher integration density.

We have developed a novel scintillator for neutron imaging by combining enriched 6LiF with the well-known CsI:Tl scintillator screens. The CsI:Tl scintillator is attractive for imaging applications due to its high light yield (60 000 photons/MeV) and its columnar form that provides a high spatial resolution by collimating the scintillation light to the detector. To make the scintillator sensitive to neutrons, the powdered 6LiF (95% enriched) was applied to the surface of the columnar CsI:Tl screen. Further studies to optimize performance are underway, varying the thickness of both layers. These screens can be produced with excellent uniformity over large areas. The samples were tested by coupling to charge-coupled device (CCD) cameras at the high-flux isotope reactor (HFIR) CG-1D neutron imaging beamline at the Oak Ridge National Laboratory (ORNL). Excellent quality images were acquired with an observed spatial resolution of 7 lp/mm. When coupled to a photomultiplier tube (PMT), a gamma equivalent energy (GEE) of 2.1 MeV was obtained, indicating a light signal of ~100 000 photons/neutron. In addition, the neutron and gamma signals were well-separated by pulse shape discrimination (PSD). The details of the radiographic results, including tomographic imaging, are presented here.

RESILIENT (CTRI/2018/02/011808) was a single arm, open label, phase II/III study to test if label agnostic therapy regimens guided by Encyclopedic Tumor Analysis (ETA) can offer meaningful clinical benefit for patients with relapsed refractory metastatic (r/r-m) malignancies. Patients with advanced refractory solid organ malignancies where disease had progressed following ≥2 lines of systemic treatments were enrolled in the trial. Patients received personalized treatment recommendations based on integrational comprehensive analysis of freshly biopsied tumor tissue and blood. The primary end points were Objective Response Rate (ORR), Progression Free Survival (PFS) and Quality of Life (QoL). Objective Response (Complete Response + Partial Response) was observed in 54 of 126 patients evaluable per protocol (ORR = 42.9%; 95% CI: 34.3%–51.4%, p < 0.0001). At study completion, Disease Control (Complete Response + Partial Response + Stable Disease) was observed in 114 out of 126 patients evaluable per protocol (CBR = 90.5%; 95% CI: 83.9% - 95.0%, p < 0.00001) and Disease Progression in 12 patients. Median duration of follow-up was 138 days (range 31 to 379). Median PFS at study termination was 134 days (range 31 to 379). PFS rate at 90 days and 180 days were 93.9% and 82.5% respectively. The study demonstrated that tumors have latent vulnerabilities that can be identified via integrational multi-analyte investigations such as ETA. This approach identified viable treatment options that could yield meaningful clinical benefit in this cohort of patients with advanced refractory cancers.

The aim of this study was to conduct a retrospective analysis of modalities of airway management and its impact on patients undergoing head and neck cancer surgeries. A retrospective review of the medical record of 500 patients operated from January 2008 to December 2013 was conducted at our institute. Patients were reviewed for a mode of airway management, a total length of post-operative hospital stay (PLOS), and incidence of elderly patients in the total number of head and neck cancer surgeries posted for various diagnostic and definitive treatments. Out of 500 patients, 462 patients (92.4%) underwent nasal intubation, of which 320 underwent fiberoptic (FO) intubation (64%), 7 underwent tracheotomies after completion of surgery (1.4%), and 3 underwent at the beginning of surgery (0.6%). The remaining 38 patients (7.6%) underwent oral intubation. Nasotracheal intubation using fiberoptic bronchoscopy is the most preferred technique for the management of a difficult airway. Efficient airway management during the perioperative period significantly reduces the post-operative length of hospital stay and morbidity.

BACKGROUND Third epidermoid tumors are a rare finding. The appearance of these tumors often makes them difficult to diagnose, and thus they require multimodality imaging. CASE SUMMARY A 48-year-old male patient reported to our hospital with complaints of vomiting and severe headache. The patient also complained of involuntary micturition for the past five days. We used a combination of computed tomography (CT) and magnetic resonance imaging (MRI) imaging modalities to confirm the presence of a malignant epidermoid cyst arising from the third ventricle. A contrast-enhanced CT of the head demonstrated minimal perilesional enhancement while an MRI revealed a large, lobulated and septated T2 hyperintense mass arising from the third ventricle. The maximum size of the lesion measured 73 mm × 65 mm × 64 mm in size. CONCLUSION Malignant epidermoid arising from the third ventricle in an adult male was reported using a combination of CT, MRI, and MR spectroscopy.

The present paper aims to understand the fear of falling (FOF) and risk factors associated with FOF in community-dwelling individuals aged over 60 years in Pune, India. The study examined a random sample of 351 community-dwelling older adults. Data on demographic characteristics, health conditions, history of falls, and psychological factors were collected using a pre-tested, structured questionnaire. The Falls Efficacy Scale International (FES-I) was used to measure FOF. Univariate and bivariate logistic regression analyses were carried out to examine associations between various factors and FOF. A high FES-I score was significantly associated with older age, females, unmarried status, education less than 6 years, living alone, unstable balance and gait, hypertension, arthritis, previous falls, self-reported loss of confidence, and depression. Adults older than 70 years of age (odds ratio, OR = 2.411), those with a history of falls (OR = 2.285), those reporting loss of confidence in the past 6 months (OR = 6.766), who had answered yes to the direct question of FOF (OR = 4.632), and had unstable balance (OR = 2.522) were also more likely to have higher FES-I values. A large number of older adults expressed concerns about falling and we also found several factors to be associated with developing FOF, supporting the need for screening. Thus, further research is needed in order to understand the relationship between severity of FOF and actual fall events for developing preventive measures which can be implemented before FOF becomes a problem.

Patient: Female, 71 Final Diagnosis: Anaplastic thyroid carcinoma Symptoms: Breathlessness Medication: — Clinical Procedure: Total thyroidectomy along with left modified radical neck dissection Specialty: Oncology Objective: Unusual clinical course Background: Anaplastic thyroid carcinoma (ATC) is an uncommon and aggressive form of human cancer. Despite advancement in multimodal therapy for patients with ATC, the prognosis remains poor. Most patients presenting with ATC have metastasis to the lungs and regional lymph nodes. Gastrointestinal tract metastasis is a rare entity observed among patients with ATC. We report a case of ATC with gastrointestinal metastasis. Case Report: A 72-year-old euthyroid female with hypertension presented to the clinic with swelling of the neck and breathlessness. Fine needle aspiration cytology revealed colloid goiter. Positron emission tomography and computed tomography revealed hypermetabolic, lobulated mass in left hemi-thyroid, displacing trachea, and hypermetabolic lymph nodes on the left side. The patient underwent total thyroidectomy along with left modified radical neck dissection. Histopathology and immunochemistry were suggestive of ATC with thyroid transcription factor 1 (TTF-1), cytokeratin, Pax8, and C53 positive while calcitonin and thyroglobulin were negative. The patient presented with persistent nausea and vomiting during adjuvant radiation therapy. After radiation therapy, the patient underwent upper gastrointestinal endoscopy that revealed large polypoidal lesions in the stomach. No active bleeding was observed. Biopsy results confirmed it to be metastasis from ATC. Conclusions: ATC can spread to distant sites including the gastrointestinal tract. Patients with ATC metastasis have a poor prognosis despite multimodal therapy. This is the first case of ATC with gastrointestinal metastasis reported in India.
