ABSTRACT
OBJECTIVE: A normal age-adjusted sagittal alignment is an important factor in achieving long-term functional results after lumbar spinal fusion. We aim to determine if the changes in spino-pelvic alignment (SPA) correlate with post-operative functional outcomes in patients who underwent instrumented lumbar spine surgery when the parameters were not measured before. METHOD: A retrospective review of medical records from 2012 to 2016, and radiographs of the patients who underwent instrumented fusion of the lumbar spine. The X-rays of the available preoperative lumbar spine were reviewed for SPA and compared with the last follow-up postoperative images. The patients were contacted by telephone to complete the EuroQoL 5 Dimensions 5-level questionnaire and visual analog scale for evaluation of their functional outcomes during 2017. Correlation studies were performed using Pearson's coefficient. RESULTS: Forty-six patients were included with a mean age of 53 years and a follow-up of 47 months. There was a significant improvement in the functional outcomes and pain in the whole group. All the patients showed improvement in their SPA, and those who underwent more than two levels of fusion showed a significant improvement (P<0.05). Lumbar lordosis and sacral slope had a significant correlation with postoperative clinical improvement (R=0.8). CONCLUSION: The study showed that single or double fusion has significant improvement in pain and functional outcome with a significant change in SPA.
ABSTRACT
OBJECTIVES: To investigate prevalence and association between iron deficiency anemia (IDA) and Helicobacter pylori (H. pylori). METHODS: This cross-sectional study included 79 participants with unexplained IDA. The study was carried out between November 2018 to April 2020 in the College of Medicine, Umm Al-Qura University in collaboration with Al-Noor Specialist Hospital, Makkah, Saudi Arabia. Complete blood count (CBC), serum iron, and ferritin levels were measured. Anti-H. pylori antibody was detected using anti-H. pylori immunoglobulin G enzyme-linked immunosorbent assay (ELISA). RESULTS: The prevalence of H. pylori infection among IDA patients was 62%. There was a significant difference between female and male subjects with a positive H. pylori status (p=0.001). There was also a significant difference between females and males with a positive H. pylori infection according to red blood cell count, hematocrit, mean corpuscular volume, and mean cor-puscular hemoglobin (p=0.001). CONCLUSION: The current study shows an association between H. pylori infection and unexplained IDA with significant difference between postmenopausal Saudi females and males. This will lead to more effective treatment in IDA and the eradication of H. pylori, as well as the prevention of recurrence, which are necessary and may provide a significant reduction in the overall disease burden.

BACKGROUND: Coronavirus disease-19 (COVID-19) manifested by a broad spectrum of symptoms, ranging from asymptomatic manifestations to severe illness and death. The purpose of the study was to extensively describe the clinical features and outcomes in critically ill patients with COVID-19 in Saudi Arabia. METHOD: This was a multicenter, non-interventional cohort study for all critically ill patients aged 18 years or older, admitted to intensive care units (ICUs) between March 1 to August 31, 2020, with an objectively confirmed diagnosis of COVID-19. The diagnosis of COVID-19 was confirmed by Reverse Transcriptase-Polymerase Chain Reaction (RT-PCR) on nasopharyngeal and/or throat swabs. Multivariate logistic regression and generalized linear regression were used. We considered a P value of <0.05 statistically significant. RESULTS: A total of 560 patients met the inclusion criteria. An extensive list of clinical features was associated with higher 30-day ICU mortality rates, such as requiring mechanical ventilation (MV) or developing acute kidney injury within 24 hours of ICU admission, higher body temperature, white blood cells, blood glucose level, serum creatinine, fibrinogen, procalcitonin, creatine phosphokinase, aspartate aminotransferase, and total iron-binding capacity. During ICU stay, the most common complication was respiratory failure that required MV (71.4%), followed by acute kidney injury (AKI) and thrombosis with a proportion of 46.8% and 11.4%, respectively. CONCLUSION: Among patients with COVID-19 who were admitted to the ICU, several variables were associated with an increased risk of ICU mortality at 30 days. Respiratory failure that required MV, AKI, and thrombosis were the most common complications during ICU stay.
