Alterations of absolute number or percentage of circulating white blood cell (WBC) subsets are associated with psychological and physical stress. Gender effects on the changes of circulating WBC subsets following surgical treatment have not been determined. Therefore, the current study aimed to determine whether circulating neutrophils, lymphocytes and monocytes, and neutrophil-lymphocyte ratio (N/L) are different following major surgery according to the gender. We studied 409 male patients and 212 female patients who underwent total or subtotal gastrectomy due to stomach cancer, from 1 January to 31 December in 2005. The WBC count and percentage of its subsets were obtained from database and N/L was directly calculated from the full blood count preoperatively, immediate postoperatively, and postoperative day 1, 3, 5 in a retrospective manner. Compared to preoperative values, neutrophilia, lymphopenia, monocytopenia, and increased N/L were associated with gastrectomy in all patients. In the comparison study between genders, there were significantly increased proportion of neutrophils, decreased lymphocytes and monocytes, and higher N/L in female patients than in male patients after gastrectomy. These findings indicate that female patients showed more immune-compromised response to gastrectomy than male patients.
Background: Restless legs syndrome (RLS) is a common sleep disorder, although it has a low prevalence in Asian populations. However, the reported RLS prevalence in Korean adults is mostly 4.5–12.1%, which is higher than that reported in other Asian populations. This study aimed to diagnose RLS and exclude mimicking conditions in 2 independent samples of Korean adults, and to compare its prevalence to that from previous studies performed in Asian countries. Methods: Study populations included a (1) nationwide stratified random sample (n = 2,824; age 19–79 years) and (2) community-based cohort (n = 2,685; age 47–79 years). We applied the Cambridge-Hopkins diagnostic questionnaire to diagnose RLS and differentiate it from RLS mimics. Sleep-related symptoms, mood, and medical conditions were compared between the RLS and non-RLS groups. Prior studies of the RLS prevalence in Asia were systematically reviewed and compared to our findings. Results: The adjusted RLS prevalence was 0.4 and 1.3% in populations 1 and 2, respectively. In both populations, subjects with RLS had more depression. The prevalence of RLS mimics was 5.1 and 2.6%, in populations 1 and 2, respectively. The RLS prevalence in Asia was higher when RLS was defined by the presence of essential clinical features and lower when a differential diagnosis was additionally implemented. Conclusions: The RLS prevalence in Korean adults considering RLS mimics is comparable to that in adults from other Asian countries (< 2%). The reported RLS prevalence varies depending on the diagnostic method employed.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
