The prevalence of allergic reaction in acute complications of injection of packed red blood cell in patients hospitalized in Sina Hospital, Kamyaran City, Iran, during the years 2014-2018

BACKGROUND: Acute complications are among the most common complications in blood transfusion reactions and one of the leading causes of death. The reduction in acute complications as well as blood safety and health of patients should be considered. The aim of this short report study is to determine the prevalence of allergic reactions in acute complications of packed red blood cell (RBC) injections in patients hospitalized in Sina Hospital, Kamyaran City, Iran, from 2014 to 2018.METHODS: This was a retrospective cross-sectional study with the statistical population including all patients who required blood transfusion in Sina hospital in Kamyaran City since 2014 to 2018. The standard checklist called "A form of reporting unwanted complications after blood transfusions and its related products" was used in this study. Data were entered into the SPSS statistical software. Descriptive statistics were analyzed as mean and standard deviation (SD) and analytical results were analyzed using Fisher's exact test.RESULTS: In this study, the prevalence of transfusion complications during this period was 0.016. 5 (29%) and 12 (71%) of the patients were men and women, respectively. The most common sign of blood transfusion included restlessness and tachycardia. The most common acute complication of blood transfusions was allergic reaction (47%). Based on the Fisher's exact test, a statistically significant relationship was found between the blood group, sex, and history of injection with the diagnosis of transfusion (P < 0.001).CONCLUSION: Registering the complications of blood transfusion is always a concern and important for the blood transfusion organization. In this study, it was found that the most common acute complication of blood transfusions was allergic reactions (8 out of 17)

Physiological and biochemical responses of basil (Ocimum basilicum) seedlings to different concentrations of zinc

Zinc (Zn 2+ ) is one of the essential micronutrient elements for plant growth. In the present study, effect of different concentrations of zinc on some physiological and biochemical properties of basil (Ocimum basilicum) was investigated. Basil seedlings were exposed to six zinc (ZnSO 4 ) levels (0, 50, 100, 200, 400, and 800 mg/L) in 3 days’ intervals for a period of 30 days. The root and shoot growth, leaf number and area, photosynthetic pigments content, total soluble sugars and proteins, phenolic compounds, antioxidant power and mineral elements contents including zinc and potassium were significantly increased in effect of zinc levels up to 200 mg/L. Inversely, ferrous and calcium contents was drastically decreased concomitant with increasing zinc concentration but magnesium content remained unchanged. Our results indicated a dual role of zinc with optimum concentration of 200 mg/L, and a decrease in the root and shoot growth, pigment and phenolic contents under and over optimum concentration, whereas sugars and protein accumulation were occurred concomitantly with increasing zinc in the medium. However, the decrease of these parameters at the highest zinc concentration did not reach the level of control plants, which means that this species has a high resistance against zinc metal stress and because of the relative accumulation of zinc in polluted areas may has an important role for human nutrition. In general, the results point to important role of zinc in maintaining and protecting of basil seedlings against radical oxygen species

Cellular uptake and anti-tumor activity of gemcitabine conjugated with new amphiphilic cell penetrating peptides

Gemcitabine (Gem) is used as a single agent or in combination with other anticancer agents to treat many types of solid tumors. However, it has many limitations such as a short plasma half-life, dose-limiting toxicities and drug resistance. Cell-penetrating peptides (CPPs) are short peptides which may deliver a large variety of cargo mole- cules into the cancerous cells. The current study was designed to evaluate the antiproliferative activity of gemcita- bine chemically conjugated to CPPs. The peptides were synthesized using solid phase synthesis procedure. The uptake efficiency of CPPs into cells was examined by flow cytometry and fluorescent microscopy. The synthesized peptides were chemically conjugated to Gem and the in vitro cytotoxicity of conjugates was tested by MTT assay on A594 cell line. According to the obtained results, cellular uptake was increased with increasing the concentra- tion of CPPs. On the other hand the coupling of Gem with peptides containing block sequence of arginine (R5W3R4) and some alternating sequences (i.e. [RW]6 and [RW]3) exhibited improved antitumor activity of the drug. The findings in this study support the advantages of using cell-penetrating peptides for improving intracellular delivery of Gem into tumor as well as its activity

Spironolactone loaded nanostructured lipid carrier gel for effective treatment of mild and moderate acne vulgaris: a randomized, double-blind, prospective trial

Spironolactone (SP) known as an anti-androgen drug, has been proven to be effective in treatment of acne. The quest to minimize the unnecessary systemic side effects associated with the oral drug administration of spironolactone, has led to a growing interest of loading SP on lipid nanoparticles to deliver the drug in a topical formulation. The aim of the current investigation was to prepare and compare the performance of SP loaded nanostructured lipid carrier (SP-NLC) and SP alcoholic gels (SP-ALC) on two groups of respective patient populations, group A and group B in the treatment of mild to moderate acne vulgaris. The results showed that SPNLCs were spherical in shape with an average diameter of ~240 nm. The polydispersity index (PI) and zeta potential of these nanoparticles were 0.286 and -21.4 respectively. The gels showed non-Newtonian independent pseudoplastic and shear thinning behavior. The SP-NLCs was not toxic to fibroblast cell strains at the 24 and 48 h periods. Results showed that the mean number of total lesions (37.66 ± 9.27) and non-inflammatory lesions (29.26 ± 7.99) in group A significantly decreased to 20.31 ± 6.58 (p<0.05) and to 13.95 ± 5.22 (p<0.05) respectively. A similar pattern was observed for group B where the mean number of total lesions and non-inflammatory lesions reduced from 33.73 ± 9.40 to 19.13 ± 5.53 (p<0.05) and from 25.65±8.12 to 13.45 ± 4.48 (p<0.05) respectively. The total lesion count (TLC) was significantly decreased from 37.16 ± 9.28 to 19.63 ± 6.36 (for group A; p<0.071) and 32.60 ± 9.32 to 18.33 ± 5.55 (for group B; p<0.05) respectively. After treatment with SP-NLC for 8 weeks, the water content of the skin significantly (p<0.05) increased from 37.44 ± 8.85 to 45.69 ± 19.34 instrumental units. Therefore, the SP-NLC gel may help in controlling acne vulgaris with skin care benefits

Global, regional, and national incidence of six major immune-mediated inflammatory diseases: findings from the global burden of disease study 2019

BACKGROUND: The causes for immune-mediated inflammatory diseases (IMIDs) are diverse and the incidence trends of IMIDs from specific causes are rarely studied. The study aims to investigate the pattern and trend of IMIDs from 1990 to 2019. METHODS: We collected detailed information on six major causes of IMIDs, including asthma, inflammatory bowel disease, multiple sclerosis, rheumatoid arthritis, psoriasis, and atopic dermatitis, between 1990 and 2019, derived from the Global Burden of Disease study in 2019. The average annual percent change (AAPC) in number of incidents and age standardized incidence rate (ASR) on IMIDs, by sex, age, region, and causes, were calculated to quantify the temporal trends. FINDINGS: In 2019, rheumatoid arthritis, atopic dermatitis, asthma, multiple sclerosis, psoriasis, inflammatory bowel disease accounted 1.59%, 36.17%, 54.71%, 0.09%, 6.84%, 0.60% of overall new IMIDs cases, respectively. The ASR of IMIDs showed substantial regional and global variation with the highest in High SDI region, High-income North America, and United States of America. Throughout human lifespan, the age distribution of incident cases from six IMIDs was quite different. Globally, incident cases of IMIDs increased with an AAPC of 0.68 and the ASR decreased with an AAPC of −0.34 from 1990 to 2019. The incident cases increased across six IMIDs, the ASR of rheumatoid arthritis increased (0.21, 95% CI 0.18, 0.25), while the ASR of asthma (AAPC = −0.41), inflammatory bowel disease (AAPC = −0.72), multiple sclerosis (AAPC = −0.26), psoriasis (AAPC = −0.77), and atopic dermatitis (AAPC = −0.15) decreased. The ASR of overall and six individual IMID increased with SDI at regional and global level. Countries with higher ASR in 1990 experienced a more rapid decrease in ASR. INTERPRETATION: The incidence patterns of IMIDs varied considerably across the world. Innovative prevention and integrative management strategy are urgently needed to mitigate the increasing ASR of rheumatoid arthritis and upsurging new cases of other five IMIDs, respectively.

Global, regional, and national burden of disorders affecting the nervous system, 1990–2021: a systematic analysis for the Global Burden of Disease Study 2021

BACKGROUND: Disorders affecting the nervous system are diverse and include neurodevelopmental disorders, late-life neurodegeneration, and newly emergent conditions, such as cognitive impairment following COVID-19. Previous publications from the Global Burden of Disease, Injuries, and Risk Factor Study estimated the burden of 15 neurological conditions in 2015 and 2016, but these analyses did not include neurodevelopmental disorders, as defined by the International Classification of Diseases (ICD)-11, or a subset of cases of congenital, neonatal, and infectious conditions that cause neurological damage. Here, we estimate nervous system health loss caused by 37 unique conditions and their associated risk factors globally, regionally, and nationally from 1990 to 2021. METHODS: We estimated mortality, prevalence, years lived with disability (YLDs), years of life lost (YLLs), and disability-adjusted life-years (DALYs), with corresponding 95% uncertainty intervals (UIs), by age and sex in 204 countries and territories, from 1990 to 2021. We included morbidity and deaths due to neurological conditions, for which health loss is directly due to damage to the CNS or peripheral nervous system. We also isolated neurological health loss from conditions for which nervous system morbidity is a consequence, but not the primary feature, including a subset of congenital conditions (ie, chromosomal anomalies and congenital birth defects), neonatal conditions (ie, jaundice, preterm birth, and sepsis), infectious diseases (ie, COVID-19, cystic echinococcosis, malaria, syphilis, and Zika virus disease), and diabetic neuropathy. By conducting a sequela-level analysis of the health outcomes for these conditions, only cases where nervous system damage occurred were included, and YLDs were recalculated to isolate the non-fatal burden directly attributable to nervous system health loss. A comorbidity correction was used to calculate total prevalence of all conditions that affect the nervous system combined. FINDINGS: Globally, the 37 conditions affecting the nervous system were collectively ranked as the leading group cause of DALYs in 2021 (443 million, 95% UI 378–521), affecting 3·40 billion (3·20–3·62) individuals (43·1%, 40·5–45·9 of the global population); global DALY counts attributed to these conditions increased by 18·2% (8·7–26·7) between 1990 and 2021. Age-standardised rates of deaths per 100 000 people attributed to these conditions decreased from 1990 to 2021 by 33·6% (27·6–38·8), and age-standardised rates of DALYs attributed to these conditions decreased by 27·0% (21·5–32·4). Age-standardised prevalence was almost stable, with a change of 1·5% (0·7–2·4). The ten conditions with the highest age-standardised DALYs in 2021 were stroke, neonatal encephalopathy, migraine, Alzheimer's disease and other dementias, diabetic neuropathy, meningitis, epilepsy, neurological complications due to preterm birth, autism spectrum disorder, and nervous system cancer. INTERPRETATION: As the leading cause of overall disease burden in the world, with increasing global DALY counts, effective prevention, treatment, and rehabilitation strategies for disorders affecting the nervous system are needed

Physiological and biochemical responses of Hibiscus sabdariffa to drought stress in the presence of salicylic acid

Abstract Salicylic acid (SA) is one of the important signal molecules, which modulates plant responses to environmental stress. In the present work, impact of exogenous SA on some physiological and biochemical traits of Hibiscus sabdariffa in response to drought stress was studied. Hibiscus sabdariffa seedlings were exposed to six drought levels (0, -0.05, -0.1, -0.5, -0.75, and 1 MPa) with two SA concentrations (0 and 500 µM) in 5 days intervals up to 20 days in a factorial design. During drought stress period, the root and shoot growth, relative water content, pigments content, non-reducing sugar and starch content was significantly decreased. SA treatment cause prevention of the growth reduction and improvement of relative water content. Protein concentration was roughly unchanged during drought stress with SA, while, reducing sugars accumulates and non-reducing sugars and starch significantly decreases. The results show that exogenous SA application on leaves during drought stress can ameliorate detrimental effects of stress through reducing water loss and accumulating reducing sugars, which cause preserving turgor pressure of the cells
