A Growing Troubling Triad: Diabetes, Aging, and Falls
Ryan T. Crews,Sai V. Yalla,Adam E. Fleischer,Stephanie C. Wu
Journal of Aging Research , 2013, DOI: 10.1155/2013/342650
Abstract: There is a significant and troubling link between diabetes (DM) and falls in the elderly. Individuals with DM are prone to fall for reasons such as decreased sensorimotor function, musculoskeletal/neuromuscular deficits, foot and body pain, pharmacological complications, and specialty (offloading) footwear devices. Additionally, there is some concern that DM patients are prone to have more severe problems with falls than non-DM individuals. Fractures, poorer rehabilitation, and increased number of falls are all concerns. Fortunately, efforts to mitigate falls by DM patients show promise. A number of studies have shown that balance, strength, and gait training may be utilized to successfully reduce fall risk in this population. Furthermore, new technologies such as virtual reality proprioceptive training may be able to provide this reduced risk within a safe training environment. 1. Introduction From 2000 to 2010 the elderly (65+ years) population in the USA has continued its upward trend, increasing by 5.25 million (15%) to a total of 40.26 million [1]. This amounts to 13% of the entire population [1]. Thanks to the aging baby boomers population, by the year 2050 the elderly population is expected to reach 88.5 million, which would represent 20% of the total population [2]. One of the greatest health challenges facing this population is falls. In 2000 there were a reported 10,300 fatal falls by the elderly in the USA that incurred $179 million in direct medical costs [3]. There were an additional 2.6 million medically treated falls that cost $19 billion in medical costs. Other western nations report similar significant burdens with the United Kingdom reporting £981 million (US $1.9 billion) in costs for falls in those 60 or more years old in 1999 [4], and in 2001 the annual cost of care attributable to falls in those 65 or older in Australia was $86.4 million (US $66.1 million) [5]. While the cause of falls is often multifactorial, diabetes mellitus (DM) has been shown to be a significant factor. The significance of the relationship between aging, DM, and falls has been highlighted by previous work that found the annual incidence of falls in elderly individuals with DM to be 39% [6]. This paper will review the association of fall occurrence and diabetes, the association of fall severity and diabetes, and efforts to limit diabetes associated risks for falls. 2. Association between Diabetes and Falls Falls are a major concern for elderly adults with DM [7]. The high prevalence of falls in ambulatory elderly individuals with DM is well established with

Survey on Diabetes and Standardization of Polyherbal Formulation
Sai Saraswathi V
Journal of Biomedical and Pharmaceutical Research , 2012,
Abstract: Standardization of polyherbal formulation is important to validate the quality of drugs and to ensure that the consumers are getting medication which guarantees purity, safety, potency and efficacy. The present paper reports standardization of traditional ayurvedic liquid polyherbal antidiabetic formulation (Sucrogen) and diabetes survey for retrieving the information on medication along with the lifestyle of diabetic population. Sucrogen was standardized based on ayurvedic pharmacopeia physico-chemical properties, preliminary phytochemical tests, organoleptic characters, stability studies, microbial studies, TLC, HPLC, heavy metal estimation by AAS and flame photometry to fix the quality standard of this drug. Invitro anti-diabetics activity of the drug was determined using alpha amylase Inhibitory method. These studies resulted in a set of diagnostic characters essential for its standardization. The phytochemical constituents found to be present in raw materials used for the preparation of Sucrogen possibly helps in achieving the desirable therapeutic efficacy of the ayurvedic formulation.
Urodynamics of Overactive Bladder Syndrome: Pro and Con
Yalla SV,Sullivan M
Journal für Urologie und Urogyn?kologie , 2007,
Abstract: Die überaktive Blase wird mit einer Detrusor-überaktivit t in Zusammenhang gebracht und wird allgemein empirisch als solche behandelt. Allerdings bleiben Unsicherheiten bestehen im Hinblick auf die Rolle der Urodynamik in der Evaluierung von Patienten mit dieser weitverbreiteten St rung. Die urodynamische Verifizierung einer Detrusor-überaktivit t mag bei neurologisch intakten jungen Frauen mit Dranginkontinenz nicht erforderlich sein, doch ist bei lteren Personen und bei jenen, die auf konventionelle Anti-Muskarin-Therapien nicht ansprechen, irgendeine Form einer funktionalen Bewertung n tig. Ferner ist eine urodynamische Bewertung unverzichtbar für den Ausschlu von Krankheiten, die sich mit OAB hinsichtlich der Symptome und der klinischen Anzeichen überschneiden, aber auch zur pr zisen Beschreibung der vesikourethralen Dysfunktion.
Functional Studies to Assess Bladder Contractility
Sullivan M,Yalla SV
Journal für Urologie und Urogyn?kologie , 2007,
Abstract: Die Blasenkontraktilit t betrifft die intrinsische Eigenschaft der Blasenglattmuskulatur, auf eine bestimmte L nge zu kontrahieren. Intuitiv steht sie nicht nur für die St rke der Detrusorkontraktion, sondern auch für die F higkeit, eine Kontraktion ad quat aufrecht zu erhalten. Geeignete Methoden zum Messen der Blasenkontraktilit t und Methoden zur Quantifizierung dieser Messungen sind unabdingbar für eine genaue Beschreibung von Entleerungsdysfunktionen. Zahlreiche Techniken zur funktionalen Bewertung der Blasenkontraktilit t auf Basis anerkannter biomechanischer Prinzipien wurden beschrieben. Dementsprechend ist die Wahl des methodologischen Ansatzes von den Zielen der Evaluation abh ngig zu machen.

X-ray Peak Broadening Analysis and Optical Studies of ZnO Nanoparticles Derived bySurfactant Assisted Combustion Synthesis
V.?Sesha?Sai?Kumar,K.?Venkateswara?Rao
Journal of Nano- and Electronic Physics , 2013,
Abstract: In this paper, synthesis of ZnO nanoparticles is done by a simple and facile surfactant assisted combustion synthesis. The synthesis of ZnO nanoparticles has been prepared using Zinc nitrate as a precursor material, glycine as a fuel with the support of non-ionic surfactant TWEEN 80. The obtained ZnO nanoparticles have been studied using characterization techniques like X-ray diffraction (XRD), Transmission Electron Microscopy (TEM), and UV-Vis Spectroscopy. XRD results reveal that the sample is crystalline with a hexagonal wurtzite phase. X-ray peak broadening analysis was used to evaluate the crystallite sizes and lattice strain by the Williamson-Hall (W-H) analysis. Further appropriate physical parameters such as strain, stress, and energy density values were also calculated using W-H analysis with different models, viz, uniform deformation model, uniform deformation stress model and uniform deformation energy density model. Transmission electron microscopy (TEM) result reveals that the ZnO nanoparticles sample is spherical in shape showing particle sizes less than 40 nm. The optical properties of ZnO nanoparticles were studied by UV-Vis spectroscopy.
Effect of Added Arabinoxylans Isolated from Good and Poor Chapati Making Wheat Varieties on Rheological Properties of Dough and Chapati Making Quality  [PDF]

Abstract:

Arabinoxylans are the major non-starch polysaccharides in wheat and are reported to influence quality of bakery products. Arabinoxylans were isolated from good and poor chapati making varieties, added them at different levels (0.25 and 0.5 g/100g) to the same flour, interchanged with other varieties and determined the effect of arabinoxylans on rheological properties of dough and chapati making quality. Rheological properties were improved upon adding isolated arabinoxylans of good chapati making varieties to flours. Interestingly, addition of isolated arabinoxylans of good chapati making varieties to poor chapati making varieties had significantly improved the chapati quality. Sensory studies showed that chapatis prepared from flour added with arabinoxylans of good chapati varieties had soft texture and high overall quality scores. These changes are attributed to differences in their arabinose/xylose ratio. Thus, results indicated that addition of isolated arabinoxylans of good chapati making flour improved the chapati quality of poor chapati making flour.

Primary Oropharyngeal Tuberculosis—A Differential Diagnosis to Malignancy  [PDF]
Swati D. Lambor, Dheeraj V. Lambor, Sai Spoorthi R. Nayak, Archan D. Naik
International Journal of Otolaryngology and Head & Neck Surgery (IJOHNS) , 2014, DOI: 10.4236/ijohns.2014.33023
Abstract:

Tuberculosis is a communicable disease manifesting as pulmonary and extra pulmonary infection. Extra pulmonary tuberculosis involving pharynx is usually secondary to active pulmonary tuberculosis. Primary oropharyngeal tuberculosis is rare and has been reported in association with immunocompromised states like HIV-AIDS and chronic alcoholism. It has very unusual clinical presentation and sometimes mimics malignancy. We report herewith two cases of primary oropharyngeal tuberculosis, clinically mimicking a malignancy, in immunocompetent adult patients. A high index of suspicion is required to diagnose pharyngeal tuberculosis in patients presenting with ulceroproliferative mass in oropharynx. Histopathological findings of characteristic tuberculous granuloma are confirmatory. Anti-tuberculous therapy gives excellent results within two months of commencing the treatment.
