ABSTRACT
Background: The ulnar and radial arteries are the major source of blood supply in the hand, as they form the superficial and deep palmar arches. Arterial hand circulation is one of the most complicated arterial trees and connections in the body, with tremendous variations in its structure. This study aimed to evaluate whether the ulnar artery or radial artery is the dominant artery in hand circulation among plastic surgery patients at King Khalid University Hospital and to correlate the arterial hand dominance with handedness and gender. Methods: This is an analytical cross-sectional study conducted at King Khalid University Hospital in Riyadh, Saudi Arabia, on plastic surgery patients. The sampling method is purposive sampling. The calculated sample size is 28; however, 100 participants have been enlisted in the study. The data have been collected using the modified Allen test with a pulse oximeter. Results: The collective prevalence of dual arterial dominance in our study was 69% compared with 56% and 30% for Little et al (P = 0.013) and Fuhrman et al (P < 0.001), respectively. With regard to gender, women were more likely to have a dual arterial blood supply than men, with the frequency values of 85% and 58.3% for women and men, respectively (P = 0.017). Conclusions: Our study found that dual arterial supply is predominant among our participants, with 69% of our participants possessing a dual arterial supply, while 18% and 13% constitute the prevalence of radial and ulnar dominance, respectively. This contrasts with what has been reported previously in the literature.
ABSTRACT
Objective: According to findings from the previous studies, quitting smoking can significantly reduce mortality from all causes and is linked to better treatment results. Even though quitting smoking has many benefits, little is known about the evidence supporting the particular quit services offered to smokers after a cancer diagnosis. Methods: To find the articles related to area in question, different electronic databases including PubMed/Medline, Google Scholar, and EBSCO were searched on April 1st, 2023. All full text randomized controlled trials with one or more intervention and control groups that assessed the outcomes of smoking cessation interventions were included. Participants of included studies were adults diagnosed with head and neck cancer (HNC) and current smokers or those who had recently quit. There were interventions (pharmacological and/or pharmacological) that aimed to help patients with HNC succeed in quitting smoking. Results: We identified 15352 papers from the initial search from different electronic databases, 2560 remained after excluding duplicates. After screening titles and abstracts for relevance, 2345 articles were removed. Full text articles of remaining 215 papers were assessed in depth by two reviewers for their eligibility, amongst which, 210 articles were excluded. Finally, we included five papers that met the inclusion criteria in the present systematic review. Conclusion: According to the findings of this review, a multi - component strategy might very well benefit patients with HNC who smoke cigarettes after diagnosis. More studies with high methodological quality and standardized outcome measures must be conducted in this population to inform the development of smoking cessation program.
ABSTRACT
Objectives: This study assessed the prevalence of restless leg syndrome (RLS) among patients with multiple sclerosis (pwMS) and the association between RLS and MS disease duration, sleep disturbance, and daytime fatigue. Methods: In this cross-sectional study, we interviewed 123 patients via phone calls using preset questionnaires containing the International Restless Legs Syndrome Study Group (IRLSSG) diagnostic criteria, Pittsburgh Sleep Quality Index (PSQI), and Fatigue Severity Scale (FSS) diagnostic criteria validated in both Arabic and English. The prevalence of RLS in MS was compared to a group of healthy controls. Results: The prevalence of RLS in pwMS, defined by meeting all four requirements included in the IRLSSG diagnostic criteria, was 30.3% compared to 8.3% in the control group. About 27.3% had mild RLS, 36.4% presented with moderate, and the remaining had severe or very severe symptoms. Patients with MS who experience RLS had a 2.8 times higher risk of fatigue compared to pwMS without RLS. pwMS with RLS had worse sleep quality, with a mean difference of 0.64 in the global PSQI score. Sleep disturbance and latency had the most significant impact on sleep quality. Conclusion: The prevalence of RLS among MS patients was significantly higher compared to the control group. We recommend educating neurologists and general physicians to increase their awareness of the increasing prevalence of RLS and its association with fatigue and sleep disturbance in patients with MS.
