A comparison of characteristics and outcomes of patients with community-acquired and hospital-acquired COVID-19 in the United Kingdom: An observational study.

BACKGROUND AND OBJECTIVES: Reports comparing the characteristics of patients and their clinical outcomes between community-acquired (CA) and hospital-acquired (HA) COVID-19 have not yet been reported in the literature. We aimed to characterise and compare clinical, biochemical and haematological features, in addition to clinical outcomes, between these patients. METHODS: This multi-centre, retrospective, observational study enrolled 488 SARS-CoV-2 positive patients - 339 with CA infection and 149 with HA infection. All patients were admitted to a hospital within the University Hospitals of Morecambe Bay NHS Foundation Trust between March 7th and May 18th, 2020. RESULTS: The CA cohort comprised of a significantly younger population, median age 75 years, versus 80 years in the HA cohort (P = 0·0002). Significantly less patients in the HA group experienced fever (P = 0·03) and breathlessness (P < 0·0001). Furthermore, significantly more patients had anaemia and hypoalbuminaemia in the HA group, compared to the CA group (P < 0·0001 for both). Hypertension and a lower median BMI were also significantly more pronounced in the HA cohort (P = 0·03 and P = 0·0001, respectively). The mortality rate was not significantly different between the two cohorts (34% in the CA group and 32% in the HA group, P = 0·64). However, the CA group required significantly greater ICU care (10% versus 3% in the HA group, P = 0·009). CONCLUSION: Hospital-acquired and community-acquired COVID-19 display similar rates of mortality despite significant differences in baseline characteristics of the respective patient populations. Delineation of community- and hospital-acquired COVID-19 in future studies on COVID-19 may allow for more accurate interpretation of results.

Challenges of training and delivery of pediatric surgical services in developing economies: a perspective from Pakistan.

BACKGROUND: As the pediatric population requiring health services rises globally, developing countries are struggling to cater to the growing burden of non-communicable diseases - particularly those requiring specialized surgical care. MAIN BODY: Despite the literature supporting specialized pediatric surgical care, the developing world is far from meeting the American Pediatric Surgical Association (APSA) Manpower taskforce recommendation of at least 1 qualified pediatric surgeon per 100,000 patients (0-15 years-old). In Pakistan, there is an unmet surgical need in the pediatric population due to a multitude of short shortcomings, notably in quality and quantity of the training programs on offer, and urgent short- and long-term steps are needed to improve this dire situation. CONCLUSION: It is crucial for the global surgical community to take steps, especially with regards to pediatric surgical training, to ensure delivery of accessible and quality surgical care to the world's children.

Primary intracranial extraosseous Ewing's sarcoma.

INTRODUCTION: Common sites of occurrence of extraosseous Ewing's sarcoma include the soft tissues and bones of the lower extremity, 12 paravertebral, and retroperitoneal regions. Primary intracranial Ewing's sarcoma/pPNET is usually intraparenchymal located 13 when supratentorially, and an extraaxial epidural tumor radiographically mimicking a meningioma is extremely rare. CASE PRESENTATION: A 20-year14 old male presented to the emergency department with a 1-day history of drowsiness, headache, and fever. Neurological exam15 ination revealed decreased muscle strength (4/5) in the left lower limb. Head computed tomography scan showed an epidural 16 space-occupying lesion in the right temporoparietal region, which was assumed to be a meningioma by radiographic criteria. However, the surgical specimen was diagnosed as Ewing's sarcoma. CONCLUSION: Primary intracranial extraosseous Ewing's sarcoma is a rare condition that may mimic a meningioma on imaging. Physicians must be cognizant of this possibility, particularly in any young individual with a solitary contrast-enhancing dural-based lesion.
