Unveiling the Therapeutic Potential of Vitamin-E in Preventing Inflammation and Stromal Congestion in Alcoholic Liver Injury.

OBJECTIVES: The objective of the research was to investigate and assess how effective Vitamin E is in preventing or reducing liver inflammation and stromal congestion associated with alcoholic liver injury. STUDY DESIGN: This is a laboratory-based experimental study. METHODOLOGY: A total of 18 domestic rabbits were divided into groups A, B, and C. Group A was the control group and treated with normal saline as a placebo. Groups B and C were given 30% ethanol in a daily dose of 30 ml/kg/day. Additionally, group C was treated with vitamin E at 50 mg/kg/day. All three groups were sub-divided into two sub-groups I and II on the basis of experimental duration of eight weeks and four weeks respectively. The subgroups with eight weeks of experimental time duration were categorized as "category E8" and subgroups with an experimental duration of four weeks were categorized as "category E4". Liver tissue samples from each animal were subjected to staining using hematoxylin and eosin (H&E) stain for histological staining in order to assess portal inflammation and to measure the sizes of hepatic sinusoids and central veins to evaluate hepatic congestion. RESULTS: A statistically significant variance was observed in the size of central veins, hepatic sinusoids, and invasion of inflammatory cells in portal areas across and between the groups within categories E4 and E8. Animals treated with vitamin E exhibited lower invasion of inflammatory cells and larger central veins and sinusoids compared to those not treated with vitamin E. CONCLUSION: Vitamin E may have a significant role in reducing or limiting the infiltration of inflammatory cells and could help prevent hepatic congestion in cases of alcoholic liver injury.

Functional and radiological outcomes of atypical femur fractures among elderly in Karachi, Pakistan.

OBJECTIVE: To assess the functional and radiological outcomes in a unique class of fractures i.e. atypical femur fractures and to assess the effects of osteoblastic agents in healing. METHODS: It is a retrospective observational study conducted at Aga Khan University Hospital, Karachi, Pakistan. All patients with atypical femur fractures who were surgically managed with intramedullary nailing from January, 2013 to June, 2017 and with a follow-up till December 2019, were included in the study. Radiological outcomes were expressed as mean healing time and functional outcomes were recorded as mean Short Musculoskeletal Functional Assessment (SMFA) score. RESULTS: A total of twenty-four patients were included in this study. Mean age of patients was 65.8 ± 8 years. Mean healing time was 10 ±3.2 months post operatively. Two patients underwent redo procedures. No other complications like paresthesia or weakness was observed in any patients. All the patients reported a good score on SMFA ranging from 19% to 31%. CONCLUSION: Intra-medullary nailing shows a promising result in treatment of atypical femur fractures. Use of post-operative osteoblastic supplements showed statistically significant results with early healing time (p=0.008 [95% CI]).

Self-healing epoxy coating synthesis by embedment of metal 2-methyl imidazole and acetylacetonate complexes with microcapsules.

The restoration of mechanical properties is desired for creating the self-healing coatings with no corrosion capabilities. The encapsulation of epoxy resins is limited by various factors in urea and melamine formaldehyde microcapsules. An improved method was developed, where epoxy resin was encapsulated by individual wrapping of poly(melamine-formaldehyde) and poly(urea-formaldehyde) shell around emulsified epoxy droplets via oil-in-water emulsion polymerization method. The synthesized materials were characterized analytically. The curing of the epoxy was achieved by adding the [Ni/Co(2-MI)6].2NO3 as a latent hardener and iron acetylacetonate [Fe(acac)3] as a latent accelerator. Isothermal and non-isothermal differential scanning calorimetric analysis revealed lower curing temperature (Tonset = 116 °C) and lower activation energies (Ea ≈ 69-75 kJ/mol). The addition of microcapsules and complexes did not adversely alter the flexural strength and flexural modulus of the epoxy coatings. The adhesion strength of neat coating decreased from 6310.8 ± 31 to 4720.9 ± 60 kPa and percent healing increased from 50.83 to 67.45% in the presence of acetylacetonate complex at 10 wt% of microcapsules.

Developments in hybrid operating room, neurointensive care unit, and ward composition and organization for stroke management.

Stroke is the leading cause of adult disability in the US. Rapid diagnosis and treatment of stroke, in addition to efficacious rehabilitation, is invaluable. The present review aims to report the recent improvements in hybrid operating rooms (hybrid ORs), and in the organization of Neurological intensive care unit (NICUs) and dedicated stroke wards (SWs), which contribute to enhanced stroke treatment. A PubMed literature review was conducted in addition to the collection of other online media releases regarding recent organizational advances in stroke care. PubMed keywords included but were not limited to "neurological intensive care unit," "hybrid operating room," and "stroke ward," while all other online information regarding recent advances in the physical organization was selected and synthesized in accord with its relevance. The current research indicates that hybrid ORs facilitate surgical innovation and improved patient care through the colocation of advanced imaging modalities and surgical capabilities. Moreover, the recent reorganization of NICUs and SWs may lead to better-quality initial treatment and rehabilitation. The present review also considers the current ER triage protocol for stroke patients, and it concludes with relevant considerations relating to the role of the physical hospital structure and organization in stroke care.
