Medium-term mortality after hip fractures and COVID-19: A prospective multi-centre UK study / 中华创伤杂志(英文版)

PURPOSE@#The COVID-19 pandemic has caused 1.4 million deaths globally and is associated with a 3-4 times increase in 30-day mortality after a fragility hip fracture with concurrent COVID-19 infection. Typically, death from COVID-19 infection occurs between 15 and 22 days after the onset of symptoms, but this period can extend up to 8 weeks. This study aimed to assess the impact of concurrent COVID-19 infection on 120-day mortality after a fragility hip fracture.@*METHODS@#A multi-centre prospective study across 10 hospitals treating 8% of the annual burden of hip fractures in England between 1st March and 30th April, 2020 was performed. Patients whose surgical treatment was payable through the National Health Service Best Practice Tariff mechanism for "fragility hip fractures" were included in the study. Patients' 120-day mortality was assessed relative to their peri-operative COVID-19 status. Statistical analysis was performed using SPSS version 27.@*RESULTS@#A total of 746 patients were included in this study, of which 87 (11.7%) were COVID-19 positive. Mortality rates at 30- and 120-day were significantly higher for COVID-19 positive patients relative to COVID-19 negative patients (p < 0.001). However, mortality rates between 31 and 120-day were not significantly different (p = 0.107), 16.1% and 9.4% respectively for COVID-19 positive and negative patients, odds ratio 1.855 (95% CI 0.865-3.978).@*CONCLUSION@#Hip fracture patients with concurrent COVID-19 infection, provided that they are alive at day-31 after injury, have no significant difference in 120-day mortality. Despite the growing awareness and concern of "long-COVID" and its widespread prevalence, this does not appear to increase medium-term mortality rates after a hip fracture.

Epidemiology of urinary tract infections in the children in zagazig university children's hospital

Background: The most common bacterial infection among children is Urinary Tract Infection (UTI). Early diagnosis and good treatment of UTI is very important as the risk of renal damage is increased in children below the age of five years which result of morbidity. The aim of this study was to estimate the prevalence of urinary tract infection (UTI) in children attending Pediatric outpatient clinic in Zagazig University Children's Hospital. Also to determine related risk factors, isolate the organisms that cause UTI in children and antibiotics susceptibility patterns. Methods: This Cross sectional descriptive study, was conducted on 600 children, (377 males and 223 females) from two to seven years old attending to pediatric outpatient clinic ZUH , All patient groups were exposed to full medical history, physical examination, Dipstick analysis by using both nitrite and leukocyte esterase detector, Microscopic examinations and urine culture for positive cases.Results: The prevalence of UTI between children included in the current study was (7%). LE positive were 56 (9.3%), Nitrite positive were 47 (7.8%) and both LE and Nitrite positive were 17 (2.8%). Conclusion: The prevalence of UTI was 7 % in our study, E - Coli was detected to be the most common organism, Cefotaxime and Amikacin were detected to be the most common antibiotic sensitive to the isolates

Eeffect of melatonin on cerulein-induced pancreatitis in adult male albino rats: histological and histochemical study

Acute pancreatitis [AP] is a complex disease associated with significant complications and a high rate of mortality. The aim of this work was to study the effect of the antioxidant melatonin on cerulein-induced pancreatitis in adult male albino rats. Thirty two adult male albino rats were used and randomly divided into four groups: first group [control]; second group [melatonin treated]; third group [cerulein treated] and fourth group [melatonin and cerulein treated group]. At sacrifice, blood samples were drawn for biochemical study and pancreas specimens were prepared for histological, and histochemical study. Melatonin reduced serum amylase and lipase activities, which were highly significantly elevated in cerulein induced pancreatitis. Histologically there was wide separation between pancreatic lobules, the acinar cells showed degeneration and vacuolation and lost their zymogen granules. There was dilatation and congestion of blood vessels, interstitial hemorrhage and cellular infiltration. Ultrastructurally, there was disorganized dilated rough endoplasmic reticulum [RER], marked decrease in zymogen granules, mitochondrial damage and cytoplasmic vacuoles. Immunohistochemically, pancreatic sections of cerulein treated rats showed a strong immune reaction for transforming growth factor-beta [TGF-beta] and vascular endothelial growth factor [VEGF]. Melatonin improved the biochemical, histological, and histochemical picture of pancreas. In conclusion, melatonin was found to be effective in cerulein-induced acute pancreatitis by preventing oxidative stress so prevents other pathological mechanisms of AP from being developed inside acinar cells
