Two by Two Factorial Design using Metformin and Curcumin for Second Primary Head and Neck Cancer Prevention Trial.

Objective: The 2x2 factorial design is an effective method that allows for multiple comparisons, especially in the context of interactions between different interventions, without substantially increasing the required sample size. In view of the considerable preclinical evidence for Curcumin and Metformin in preventing the development and progression of head and neck squamous cell carcinoma (HNSCC), this study describes the protocol of the clinical trial towards applying the drug combination in prevention of second primary tumors.

Methods: We have applied the trial design to a large phase IIB/III double-blind, multi-centric, placebo-controlled, randomized clinical trial to determine the safety and efficacy of Metformin and Curcumin in the prevention of second primary tumours (SPT) of the aerodigestive tract following treatment of HNSCC (n=1,500) [Clinical Registry of India, CTRI/2018/03/012274].

Aspergilloma in Non-tuberculous Cavities in the Lung: Not to Get Startled.

Aspergillus which is normally found as a colonizer in healthy individuals can manifest in various forms in patients with diseased lung or immunocompromised status. Aspergilloma is one such manifestation whereby the fungus makes its way into preexisting cavities in the lung, the most common underlying etiology being old tuberculous cavities, especially in countries with high TB prevalence. However, we hereby report two cases of Aspergillus infestation as aspergilloma in cavities because of extremely rare causes, namely pulmonary thromboembolism and idiopathic pulmonary fibrosis, respectively.

Near-Infrared Spectroscopy Monitoring in Pediatric Anesthesiology: A Pro-Con Discussion.

Near-infrared spectroscopy (NIRS) has been increasingly used as a non-invasive measurement of cerebral tissue oxygen saturation. The aim of this short review is to discuss the benefits and drawbacks of its use in the pediatric anesthesia population. In the context of cardiac surgery, lower intraoperative NIRS values have shown a modest association with neurodevelopmental outcomes while lower neonatal intensive care unit NIRS values have been correlated with reduced neurodevelopment in children.

Using a Student-Generated Mock Magazine Issue To Improve Students' Awareness of Diverse Scientists.

This study explores whether integrating multicultural content within a genetics laboratory course affected students' awareness of diversity and their perceptions of scientists' identities. Genetics laboratory curricula typically focus on content and experimental procedures, with cursory references to the scientists who made these discoveries. The resulting poor racial and gender representation in the curricula propagate biases about the abilities and contributions of scientists from underrepresented groups, which may adversely affect the retention and success of students in these groups.

Robust Selections of Various Hematopoietic Cell Fractions on the CliniMACS Plus Instrument.

Cell separation technologies play a vital role in the graft engineering of hematopoietic cellular fractions, particularly with the rapid expansion of the field of cellular therapeutics. The CliniMACS Plus Instrument (Miltenyi Biotec) utilizes immunomagnetic techniques to isolate hematopoietic progenitor cells (HPCs), T cells, NK cells, and monocytes. These products are ultimately used for HPC transplantation and for the manufacture of adoptive immunotherapies.

Primary tuberculous osteomyelitis of the mandible: A rare case report.

Tuberculosis (TB) has become a rare disease in the developed countries but it is still a serious problem in developing countries. Incidence of tuberculous osteomyelitis of the jaw bones is very low. This rare incidence is the primary reason that this lesion gets mis-diagnosed many times.

Validating an objective video-based dyskinesia severity score in Parkinson's disease patients.

Dyskinesia is a common side effect of prolonged dopaminergic therapy in Parkinson's disease patients. Assessing the severity of dyskinesia could help develop better pharmacological and surgical interventions. We have developed a semi-automatic video-based objective dyskinesia quantifying measure called the severity score (SVS) that was evaluated on 35 patient videos.

Quantifying drug induced dyskinesia in Parkinson's disease patients using standardized videos.

This paper presents a video based method to quantify drug induced dyskinesias in Parkinson's disease (PD) patients. Dyskinetic movement in standard clinical videos of patients is analyzed by tracking landmark points on the video frames using non-rigid image registration. The novel application of Point Distribution Models (PDM) allows geometric variations and covariations of the landmark points to be captured from each video sequence.
