Diabetic wounds or ulcers are major complication of diabetes mellitus. Diabetes is a metabolic disorder that impedes the normal steps of wound healing process Major increase in morbidity in diabetic patients is due to macro and micro vascular complications including failure of wound healing process. Diabetes is the cause for more than 3/4 th lower limb amputation Increased glucose in the tissue precipitates infection. The aim of this study is to establish whether topical application of human epidermal growth factor enhance wound healing better than conventional povidone-iodine dressing in diabetic wounds. For one group of patients, topical application of recombinant human epidermal growth factor gel over the wound and wound dressing was done twice daily For other group of patients, topical application of povidone-iodine over the wound and wound dressing done twice daily. The Human Epidermal Growth Factor Application group patients equally belonged to the male gender class interval (n=15, 50%). In the Conventional Povidone Iodine Dressing group patients, majority belonged to the male gender class interval (n=15, 50%). The association between the intervention groups and gender distribution is considered to be not statistically significant since p > 0.05 as per fishers exact test. The results of the study conclude that the topical application of human epidermal growth factor enhances wound healing significantly and is better than conventional povidine iodine dressing.
images, computed tomography (CT) images plays two vital roles, namely defining pretreatment tumor and tumor responses to treatment, of which the later impacts greatly the treatment decision. However, the recent modern advancements in imaging analysis, namely radiomics, extracts additional quantitative features from medical images, such as CT, positron emission tomography (PET), and magnetic resonance imaging (MRI), to uncover patient's response to treatment as well as the chance of developing side effects (Gillies et al., 2016). CT radiomics is a conventionally practiced prognostic feature in radiation therapy. Various clinical, phantom, and texture analysis of CT radiomics have discussed both its reliability in assessing tumor response to treatment and its limitations. However, such limitations outweigh the established purpose of CT radiomics (Nardone et al.,
Background: Bile acids (BAs), which act in the liver-brain axis, are liver-derived signaling molecules found in the brain. However, how they modulate neurological function remains largely unknown. Methods: To assess the role of BAs in the brain, we generated mice with absent 12-αhydroxylase (Cyp8b1), a BA synthesis enzyme, and determined if brain BA levels were altered in these mice, and if and how this may modulate neuronal function. Results: The absence of CYP8B1 increased brain levels of the primary BA chenodeoxycholic acid (CDCA), and decreased ischemic stroke infarct area. Furthermore, CDCA administration reduced ischemic stroke lesion area in wild-type mice. Excitotoxicity due to elevated extra-cellular glutamate contributes to neuronal death in ischemic stroke. Neurons from Cyp8b1-/- mice showed reduced susceptibility to glutamate-induced toxicity, and exogenous CDCA reduced glutamate-induced toxicity in neurons from wild-type mice. These data suggest that CDCA-mediated decreases in excitotoxic neuronal death contributes to the reduced stroke lesion area in Cyp8b1-/- mice. Aberrant N-methyl-D-aspartate receptor (NMDAR) over-activation contributes to excitotoxicity. CDCA decreased NMDAR-mediated excitatory post-synaptic currents (EPSCs) in wild-type brain slices, by reducing over-activation of the NMDAR subunit GluN2B. In line with this, synaptic NMDAR activity was also decreased in Cyp8b1-/- brain slices. Expression level and synaptic distribution of GluN2B were unaltered in Cyp8b1-/- mice, suggesting that CDCA may directly antagonize GluN2B-containing NMDARs. Conclusions: Our data suggests that CDCA acts in the liver-brain axis and decreases the aberrant over-activation of neuronal GluN2B-containing NMDARs, contributing to neuroprotection.
Primary localized cutaneous amyloidosis is a group of rare conditions where amyloid deposition is limited to the skin without systemic manifestations. Most cases are sporadic; however, mutations in the oncostatin M receptor (OSMR) and interleukin-31 receptor A (IL31RA) genes can cause a familial form of the condition in up to 10% of cases. Here, we describe a family in which 8 female individuals are affected by either macular amyloidosis or amyloidosis cutis dyschromica. To the best of our knowledge, a sex-specific expression or the coexistence of 2 different phenotypes of primary localized cutaneous amyloidosis in 1 pedigree has not yet been reported.
Purpose:The purpose of this present work was to fabricate an in‐house software based respiratory monitoring, controlling and breath‐hold device using computer software programme which guides the patient to have uniform breath hold in response to request during the gated radiotherapy.Methods:The respiratory controlling device consists of a computer, inhouse software, video goggles, a highly sensitive sensor for measurement of distance, mounting systems, a camera, a respiratory signal device, a speaker and a visual indicator. The computer is used to display the respiratory movements of the patient with digital as well as analogue respiration indicators during the respiration cycle, to control, breath‐hold and analyze the respiratory movement using indigenously developed software.Results:Studies were conducted with anthropomophic phantoms by simulating the respiratory motion on phantoms and recording the respective movements using the respiratory monitoring device. The results show good agreement between the simulated and measured movements. Further studies were conducted for 60 cancer patients with several types of cancers in the thoracic region. The respiratory movement cycles for each fraction of radiotherapy treatment were recorded and compared. Alarm indications are provided in the system to indicate when the patient breathing movement exceeds the threshold level. This will help the patient to maintain uniform breath hold during the radiotherapy treatment. Our preliminary clinical test results indicate that our device is highly reliable and able to maintain the uniform respiratory motion and breathe hold during the entire course of gated radiotherapy treatment.Conclusion:An indigenous respiratory monitoring device to guide the patient to have uniform breath hold device was fabricated. The alarm feature and the visual waveform indicator in the system guide the patient to have normal respiration. The signal from the device can be connected to the radiation unit in near future to carry out the gated radiotherapy treatment.
