Modern Plastic Surgery (MPS) , 2012, DOI: 10.4236/mps.2012.23015
Abstract: A 45-year-old woman underwent a delayed breast reconstruction with a free Deep Inferior Epigastric Perforator Flap (DIEP flap) with total flap failure on the fourth postoperative day. Hematological investigation to exclude thrombofilia revealed a resistance to activated protein C (APC) with a factor V Leiden heterozygous mutation. The postoperative course was further complicated by delayed wound healing probably due to ascorbic acid (Vitamin C) related cytotoxic activity to fibroblasts. The surgeon must be aware of the use of preoperative nutritional supplement administration among patients. Future cost-effectiveness analyses should be made to warrant preoperative thrombophilia screening to prevent free flap failures.

Abstract: Pyrolysis temperature and feedstock type used to produce biochar influence the physicochemical properties of the obtained product, which in turn display a range of results when used as soil amendment. From soil carbon (C) sequestration strategy to nutrient source, biochar is used to enhance soil properties and to improve agricultural production. However, contrasting effects are observed from biochar application to soil results from a wide range of biochar’s properties in combination with specific environmental conditions. Therefore, elucidation on the effect of pyrolysis conditions and feedstock type on biochar properties may provide basic information to the understanding of soil and biochar interactions. In this study, biochar was produced from four different agricultural organic residues: Poultry litter, sugarcane straw, rice hull and sawdust pyrolysed at final temperatures of 350°C, 450°C, 550°C and 650°C. The effect of temperature and feedstock type on the variability of physicochemical properties of biochars was evaluated through measurements of pH, electrical conductivity, cation exchange capacity, macronutrient content, proximate and elemental analyses, Fourier transform infrared spectroscopy (FTIR) and thermogravimetric analyses. Additionally, an incubation trial was carried under controlled conditions to determine the effect of biochar stability on CO2-eq emissions. Results showed that increasing pyrolysis temperature supported biochar stability regardless of feedstock, however, agricultural properties varied widely both as an effect of temperature and feedstock. Animal manure biochar showed higher potential as nutrient source rather than a C sequestration strategy. Improving the knowledge on the influence of pyrolysis temperature and feedstock type on the final properties of biochar will enable the use of better tailored materials that correspond to the expected results while considering its interactions with environmental conditions.

Pharmacology & Pharmacy (PP) , 2013, DOI: 10.4236/pp.2013.41012
Abstract: Human and animal studies have shown that some drugs and chemical agents have potential hepatotoxic effects. The hepatotoxic effect of drugs and some chemical agents is reported to be associated with the generation of reactive oxygen species (ROS). These ROS are reported to be associated with lipid peroxidation in the liver. This mechanism has led to continuous evaluation of the hepatoprotective effect of antioxidants in humans and animals. Among the antioxidants been evaluated is vitamin C which is a water soluble antioxidant. Reports have linked vitamin C with hepatoprotective property in animals and humans. It synergistic hepatoprotective effect with other antioxidants was also reported. Due to these reports a comprehensive literature review on the hepatoprotective property of vitamin C in humans and animals was performed. It was observed that vitamin C exhibited a reputable hepatoprotective effect in humans and animals. Research showed that vitamin C inhibited hepatotoxicity induced by drugs, heavy metals, organophosphate insecticides and some chemical agents. Vitamin C was reported to normalized levels of serum alanine aminotransferase, aspartate aminotransferase, gamma glutamine, alkaline phosphatase, lactate dehydrogenase and malondialdehyde and serum bilirubin in intoxicated animals. It potentiates the activities of free radical scavengers, superoxide dimutase, and catalase glutathione peroxidase thereby preventing microsomal lipid peroxidation, liver fibrosis, liver necrosis and hepatic inflammation. In humans vitamin C was reported to be beneficial in non alcoholic steatohepatitis and in patients with fatty liver disease. Hepatoprotective property of vitamin C is attributed to it antioxidant property. Vitamin C (ascorbic acid) which is a major water-soluble antioxidant is believed to decrease lipid peroxidation either directly or indirectly by regenerating vitamin E. Vitamin C is an important free radical scavenger in extracellular fluids, trapping radicals and protecting biomembranes from peroxide damage. Vitamin C effectively scavenges singlet oxygen, superoxide, hydroxyl, water soluble peroxyl radical and hypochlorous acid. It is also reported to be an excellent source of electrons and therefore can donate electrons to free radicals such as hydroxyl and super oxide radicals and quench their activity. Vitamin C is an essential co-factor involved in many biochemical functions and acts as an electron donor or reducing agent. In this review it is observe that vitamin C has hepatoprotective effect which increases

Case Reports in Clinical Medicine (CRCM) , 2013, DOI: 10.4236/crcm.2013.21020

This is a case of 52 years old male patient with chronic obstructive pulmonary disease (COPD) who developed semi-invasive pulmonary aspergillosis while on pegylated-interferon alpha-2a and for chronic hepatitis C infection. This complication is very rarely seen during interferon therapy for other any purposes. Pulmonary aspergillosis in particular group of chronic hepatitis C patients under immunosupressive therapy should also be in mind and interdisciplinary medical cooperation might be needed during the treatment for immune-suppressed patients. Pulmonary aspergillosis is also discussed from many aspects in the light of the literature.

Abstract: Summary: There is no evidence for comorbidity diabetes and hepatitis C virus infection in the Congo. The aim of this work was to determine the seroprevalence and molecular biodiversity of HCV in order to contribute to improving the management of Congolese diabetics. Patients and methods: It was a cross-sectional study that took place from 1 February to 30 September 2018 at the Brazzaville University Hospital, the Diabcare Health Center and the Adolphe Cissé Hospital in Pointe-Noire. It concerned diabetic patients followed in Brazzaville and Pointe-Noire agreeing to the study, after obtaining the opinion of the ethics committee of the research in health science. All samples collected were screened for the presence of anti HCV Ab using a rapid ALERE HCV test and the Monolisa HCV Ag-Ab ultra test for confirmation in Congo. Detection of the viral RNA was done by PCR retrotranscription and genotyping was performed according to the reverse hybridization technique in France. Data analysis was done with EpiInfo 6.0 software (2016); the proportions were compared using the Chi-square test or the Fisher test at the significance level of 5%. Results: Of 447 patients with diabetes mellitus, 49 had HCV positive serology and the sex ratio was 0.63. Seroprevalence of AC anti HCV was 11% (49/447); HCV RNA was detectable in 71.4% (n = 35) patients. The average age of the population was 62 ± 10 years with extremes ranging from 26 to 82 years. The circulating genotypes were 4 (97.1%) and 1 (2.8%). Subtyping was defined in 17.64% (n = 6) of genotype 4 patients; undefined in 82.36% (n = 28) of Genotype 4 patients, and in one of genotype 1 patients. The subtypes identified were subtype 4e (60%), subtype 4e (8.8%), subtype 4a/4c/4d (5.8%), and subtype 4h (2.9%). Conclusion: The prevalence of HCV is high in our study. These are important data for the improvement of the management of diabetics.

Abstract: Dyslipidemia, including low levels of high-density lipoprotein cholesterol (HDL-C), is a relatively well-established risk factor for cardiovascular disease. However, the independent association between changes in HDL-C and the subsequent risk of cardiovascular events has not been well studied. The retrospective cohort analysis was conducted to evaluate the association between changes in HDL-C and cardiovascular (CV) and/or cerebrovascular (CB) events among statin-treated patients. Patient demo-graphics, clinical characteristics, laboratory data, and CV/CB events, were collected from the UK General Practice Research Database. The association between the risk of an incident event and changes in patients’ HDL-C was estimated using multivariate Cox pro-portional hazards models. Among 17,923 statin-treated patients with an average follow-up of 1.9 years, there were 815 CV events and 220 CB events. The average change in HDL-C experienced was 0.4 mg/dL, ranging from 11 mg/dL average decrease in the lowest change quartile to 12 mg/dL average increase in the highest change quartile. CV events occurred at an average overall rate of 21 per 1000 person-years and 17 per 1000 person-years among individuals in the highest quartile of change in HDL-C levels. Fully adjusted Cox regression estimated a 6% decrease in hazards (HR, 0.94; 95% CI, 0.90, 0.98) of a subsequent CV event associated with each 5 mg/dL increase in HDL-C. Similar results (HR: 0.95, 95% CI, 0.92, 0.98) were observed when assessing the association with changes in HDL-C and the composite outcome of CV/CB event. Among statin-treated patients from UK clinical practices, increases in HDL-C were associated with a significantly decreased relative risk of experiencing CV/CB events with a more pronounced effect on CV events. Therefore, a more aggressive treatment to increase HDL-C could benefit patients by reducing the risk of CV/CB events.
