AI Article Synopsis
- The study investigates the impact of obesity on COVID-19 morbidity among patients with pneumonia.
- Patients with obesity exhibited worse respiratory function, higher inflammatory markers, longer hospital stays, and required increased oxygen support compared to non-obese patients.
- However, obesity did not correlate with higher mortality rates in the patients studied.
Article Abstract
Introduction: On the last three months the new SARS-COV-2 coronavirus has created a pandemic, rapidly spreading all around the world. The aim of the study is to investigate whether obesity impacts on COVID-19 morbidity.
Methods: One hundred consecutive patients with COVID-19 pneumonia admitted in our Medical Unit were evaluated. Anthropometric parameters and past medical history were registered. Nasopharyngeal swab samples and biochemical analysis were obtained at admission and during hospital stay.
Results: Patients with (OB, 29) and without obesity (N-OB, 71) were similar in age, gender and comorbidities, with the exception of hypertension that was more frequent in OB group. At admission, inflammatory markers were higher in OB than N-OB group. OB group showed a worse pulmonary clinical picture, with lower PaO2 (57 ± 15 vs. 68 ± 14 mmHg, p = 0.042), and SaO2 (88 ± 6 vs. 92 ± 5%, p = 0.049) at admission consequently requiring higher volumes of oxygen (Fi02: 38 ± 15 vs. 29 ± 19%, p = 0.047) and a longer period to achieve oxygen weaning (10 ± 6 vs. 15 ± 7 days, p = 0.03). OB group also had positive swabs for longer time (19 ± 8 vs. 13 ± 7, days, p = 0.002), and required longer hospital stay (21 ± 8 vs. 13 ± 8, days, p = 0.0008). Partial least square regression analysis showed that BMI, age and CRP at admission were related to longer length of hospital stay, and time for negative swab. On the contrary, in this cohort, obesity did not predict higher mortality.
Conclusions: Subjects with obesity affected by COVID-19 require longer hospitalization, more intensive and longer oxygen treatment, and they may have longer SARS-COV-2 shedding.

Objective: The aim of this study was to evaluate the association of neighborhood-level and individual-level measures of socioeconomic status with readmission, complication rates, and postoperative length of stay of patients with cervical spondylotic myelopathy (CSM) in the Deep South.
Methods: The authors identified all patients undergoing surgical intervention for the treatment of CSM from November 2010 to February 2022 using Current Procedural Terminology and ICD-9/ICD-10 codes. Patient demographic, socioeconomic, perioperative, and postoperative data for each patient were collected via review of the electronic medical record.

Objective: Pediatric traumatic brain injury (TBI) represents a significant public health concern and source of resource utilization. The aim of this study was to establish the ability of the previously published pediatric Brain Injury Guidelines (pBIG) to identify patients with traumatic intracranial hemorrhage (ICH) who might not require routine repeat neuroimaging, neurosurgical consultation, or hospital admission in a large level I and level II trauma cohort.
Methods: Pediatric patients who presented with traumatic ICH between 2018 and 2022 at the included institutions were retrospectively reviewed and sorted into pBIG categories using clinical and radiographic criteria.

Objective: This retrospective study aimed to explore the association and clinical value of sequential organ failure assessment (SOFA) score on the predictors of adverse events in patients with unruptured abdominal aortic aneurysms (AAA).
Methods: A total of 322 patients from Medical Information Mart for Intensive Care IV database were enrolled. Logistic regression was conducted to explore the association between SOFA and primary outcome (need for surgery, NFS).

Background: 22q11 deletion syndrome consists of a variable grouping of phenotypic features and immunological defects secondary to the loss of genetic material located in the 22q11.2 band. The 22q11 deletion spectrum encompasses different syndromes related to the same etiology and with overlapping anomalies, including DiGeorge syndrome, velocardiofacial syndrome, among others.

Background: Solid pseudopapillary neoplasms (SPNs) arising in the body or tail of the pancreas can be amenable to laparoscopic distal pancreatectomy with or without concomitant splenectomy. The purpose of this study was to evaluate laparoscopic distal pancreatectomy for SPN using the Warshaw technique as a means to preserve spleens in children.
Methods: We reviewed our database of SPN patients 19 years and younger (January 2006-December 2023).
