Objectives: To address controversies regarding target volume delineation for adjuvant intensity-modulated radiation therapy for oral cavity squamous cell carcinoma with pedicled flap reconstruction and elective nodal irradiation (ENI).

Materials And Methods: During target volume delineation, the primary tumor bed was the pre-surgical gross tumor volume with an additional isotropic margin of 5-10 mm. Additionally, the flap and body tissue junction were given a margin of 5-10 mm (if not already given).

Incidence and clinical profile of brain metastasis treated with whole brain radiotherapy in a tertiary hospital in eastern India: A retrospective audit.

Introduction: Management of brain metastases (BM) is witnessing marked advancement worldwide and modern technologies with better outcomes are gradually being adopted in developing countries. However, data regarding current practice in this field is lacking from the Indian subcontinent prompting us to plan the current study.

Materials And Methods: A retrospective, single institutional audit was performed on 112 patients with solid tumors metastasizing to the brain treated over the last 4 years at a tertiary care center in eastern India, of which 79 were ultimately evaluable.

Cytogenetic Abnormalities in Multiple Myeloma: Incidence, Prognostic Significance, and Geographic Heterogeneity in Indian and Western Populations.

Multiple myeloma (MM) is a genetically complex and heterogeneous neoplasm in which cytogenetics is a major factor playing an important role in the risk stratification of disease. High-risk MM based upon cytogenetic classification includes primary IGH translocations t(4;14), t(14;16), t(14;20), and secondary progressive aberrations such as gain/amp(1q), 1p deletion, del(17p), and hypodiploidy. Several studies have proved that interphase FISH can detect primary as well as secondary cryptic aberrations very efficiently in lowest 5-10% abnormal plasma cell population.

Epidemiological challenges in pandemic coronavirus disease (COVID-19): Role of artificial intelligence.

World is now experiencing a major health calamity due to the coronavirus disease (COVID-19) pandemic, caused by the severe acute respiratory syndrome coronavirus clade 2. The foremost challenge facing the scientific community is to explore the growth and transmission capability of the virus. Use of artificial intelligence (AI), such as deep learning, in (i) rapid disease detection from x-ray or computed tomography (CT) or high-resolution CT (HRCT) images, (ii) accurate prediction of the epidemic patterns and their saturation throughout the globe, (iii) forecasting the disease and psychological impact on the population from social networking data, and (iv) prediction of drug-protein interactions for repurposing the drugs, has attracted much attention.

Impact of maternal substance use on offspring's cardiovascular health.

Substance use (SU) during pregnancy is on the rise, posing significant risks to the developing fetus. The adverse impact of maternal alcohol and nicotine use during the perinatal period on offspring health has been well established, including their associations with adverse cardiovascular health in offspring. However, limited studies examine the impact of other well-known SU utilized during pregnancy on offspring's cardiovascular health.

SUMO fosters assembly and functionality of the MutSγ complex to facilitate meiotic crossing over.

Crossing over is essential for chromosome segregation during meiosis. Protein modification by SUMO is implicated in crossover control, but pertinent targets have remained elusive. Here we identify Msh4 as a target of SUMO-mediated crossover regulation.

Noncovalent Association and Partitioning of Some Perfume Components at Infinite Dilution with Myelin Basic Protein Pseudophase in Normal Saline.

Myelin basic protein (MBP), one of the major protein constituents of the myelin sheath, possesses unique ligand-binding features. We present a novel equilibrium headspace gas chromatographic technique to examine the thermodynamics of noncovalent interactions between common perfume components: Lilial, Hedione, Hexylcinnamic aldehyde, and Versalide with MBP monomers and its hexameric MBP-pseudophase. A general theoretical model is used to calculate the critical aggregation concentration (cac) of MBP, perfume component binding constants with monomeric MBP, , and MBP as pseudophase, , and free energies for perfume component binding with monomeric MBP, Δ, and MBP as pseudophase, Δ.

A new open-access platform for measuring and sharing mTBI data.

Despite numerous research efforts, the precise mechanisms of concussion have yet to be fully uncovered. Clinical studies on high-risk populations, such as contact sports athletes, have become more common and give insight on the link between impact severity and brain injury risk through the use of wearable sensors and neurological testing. However, as the number of institutions operating these studies grows, there is a growing need for a platform to share these data to facilitate our understanding of concussion mechanisms and aid in the development of suitable diagnostic tools.

Efficacy of Chronomodulated Chemotherapy for Palliation of Hematemesis in Inoperable Gastric Cancer: A Single-Institutional Retrospective Study.

Context: Aside abdominal discomfort and pain, upper gastrointestinal bleeding (UGIB) significantly disgraces the quality of life (QoL), especially in inoperable gastric cancer patients. Although, in early stages, it is infrequent and often ignored, but in advanced stages, its aggressiveness often deteriorates patient's hemoglobin (Hb) level and performing status.

Aim: The aim of this study is to correlate the change in (1) the frequency of episodes of UGIB, (2) its severity in terms of Common Terminology Criteria for Adverse Events (CTCAE) grade for UGIB, and (3) Hb level with the successful completion of successive cycles of palliative chemotherapy where it becomes invariably the only modality to palliate the cancer disease.

Achieving Perfect Hand Washing: an Audit Cycle with Surgical Internees.

The aim of this study is to achieve 100% compliance in surgical hand antisepsis along with identification of areas of worst compliance and efficacies of various interventions best suited to deal with them. This audit was performed over 6 days in a tertiary care hospital in Calcutta, India, with 42 surgical internees. Compliance to ideal hand washing technique was recorded after each attempt with the first attempt as baseline.

Perception of Oncology Evaluated by Medical Students (P.O.E.M.S)-a Single Institutional Study.

Rising incidence of cancer coupled with lack of structured oncology teaching in the undergraduate (UG) medical curriculum could be detrimental by generating unmet needs in the proper care of cancer patients in the future. To determine the orientation amongst undergraduate medical students regarding Oncology as a specialization and future career option, a cross-sectional, single institutional study was conducted amongst 950 undergraduate students by using an online survey over 2 months. The perception of the subject of Oncology as a career option and the opinion regarding the need for inclusion in the undergraduate curriculum were assessed.

Sexual functioning in females with depression in remission receiving escitalopram.

Background & Objectives: Sexual functioning is a strong determinant of quality of life. Sexual dysfunction has been widely reported due to depressive disorder as well as selective serotonin reuptake inhibitors. Thus, treatment with antidepressants can culminate in a double-edged sword, leading to drug discontinuation and symptom relapse.

A Field Fire Ulcer.

Basal cell carcinoma (BCC) is the most common skin cancer, mostly affecting areas of the skin exposed to UV radiation. Though metastasis is rare, the tumour may be locally invasive with a high recurrence rate. Pathophysiology involves neoplastic transformation of the pluripotent cells of the epidermis and follicular epithelium.

Stratification of phaco-trabectome surgery results using a glaucoma severity index in a retrospective analysis.

Background: To stratify the outcomes of phacoemulsification combined with trabectome surgery using a new glaucoma severity index.

Methods: This is a retrospective, observational cohort study that included open angle glaucoma patients with visually significant cataract that had phacoemulsification combined with trabectome surgery. Exclusion criteria were follow-up less than 12 months, any other surgeries or diagnosis of neovascular or active uveitic glaucoma.

Differential Canalograms Detect Outflow Changes from Trabecular Micro-Bypass Stents and Ab Interno Trabeculectomy.

Recently introduced microincisional glaucoma surgeries that enhance conventional outflow offer a favorable risk profile over traditional surgeries, but can be unpredictable. Two paramount challenges are the lack of an adequate training model for angle surgeries and the absence of an intraoperative quantification of surgical success. To address both, we developed an ex vivo training system and a differential, quantitative canalography method that uses slope-adjusted fluorescence intensities of two different chromophores to avoid quenching.

Steroid-induced glaucoma treated with trabecular ablation in a matched comparison with primary open-angle glaucoma.

Background: To evaluate the outcomes of trabectome-mediated ab interno trabeculectomy in patients with steroid-induced glaucoma (SIG).

Design: A retrospective, observational cohort study performed in the Department of Ophthalmology, University of Pittsburgh Medical Center.

Participants: The data of 60 patients with SIG and 484 controls with primary open-angle glaucoma (POAG) matched by age, gender and glaucoma index were collected from the Trabectome Study Group database.

Combined analysis of trabectome and phaco-trabectome outcomes by glaucoma severity.

Prior glaucoma severity staging systems were mostly concerned with visual field function and retinal nerve fiber layer, but did not include intraocular pressure or medications to capture resistance to treatment. We recently introduced a simple index that combines pressure, medications, and visual field damage and applied it to stratify outcomes of trabectome surgery. In the analysis presented here, we combined data of trabectome alone and trabectome with same session cataract surgery to increase testing power and chances of effect discovery.

Gene transfer to the outflow tract.

Elevated intraocular pressure is the primary cause of open angle glaucoma. Outflow resistance exists within the trabecular meshwork but also at the level of Schlemm's canal and further downstream within the outflow system. Viral vectors allow to take advantage of naturally evolved, highly efficient mechanisms of gene transfer, a process that is termed transduction.
