BACKGROUNDAsthma is a chronic airway disease with inflammation characterized by physiological changes (airway hyper-responsiveness, AHR) and pathological changes (inflammatory cells infiltration and mucus production). Eosinophils play a key role in the allergic inflammation. But the causative relationship between eosinophils and airway inflammation is hard to prove. One of the reasons is lack of activation marker of murine eosinophils. We investigated the expression of CD69 on murine eosinophils in vitro, the relationship between the expression of CD69 on eosinophils from peripheral blood and bronchoalveolar lavage fluid and on airway inflammation in asthmatic mice.

METHODSEosinophils from peripheral blood of IL-5 transgenic mice (NJ.1638) were purified. Mice were divided into five groups: wild type mice sensitized and challenged with saline (WS group), wild type mice sensitized and challenged with ovalbumin (WO group), IL-5(-/-) mice sensitized and challenged with saline and transferred with purified eosinophils (ISE group), IL-5(-/-) mice sensitized and challenged with OVA and transferred with purified eosinophils (IOE group), IL-5(-/-) mice sensitized and challenged with OVA and transferred with purified eosinophils, pretreated with anti CD4 monoclonal antibody (IOE+antiCD4mAb group). IL-5(-/-) mice were sensitized with OVA at day 0 and day 14, then challenged with OVA aerosol. On days 24, 25, 26 and 27 purified eosinophils were transferred intratracheally to IL-5(-/-) mice. On day 28, blood and BALF were collected and CD69 expression on eosinophils measured by flowcytometry.

RESULTSPurified eosinophils did not express CD69. But eosinophils cultured with PMA + MA, IFN-gamma, IL-5 or GM-CSF expressed CD69 strongly. Eosinophils from blood of WO, WS group did not express CD69 at all. The numbers of eosinophils in BALF of WO group, IOE group, ISE group and IOE + antiCD4mAb group were significantly higher than in mice of WS group which did not have eosinophils at all. CD69 expression on eosinophils in BALF of IOE and WO groups was strong. Eosinophils in BALF of ISE and IOE + antiCDmAb groups did not express CD69. The mucus production result was similar to CD69 expression. There were eosinophils infiltration in lung slides of all groups except WS group.

CONCLUSIONActivation in airway of eosinophils could directly lead to airway inflammation.

Objective: Recently, burnout and mental health issues regarding nurses are reported increasingly. This study aimed to investigate the prevalence of anxiety symptoms among hospital nurses and determine their association with psychological and job-related factors. Methods: Data on demographics, job-related characteristics, burnout, Type A behavior patterns, self-esteem, and happiness were collected from 515 nurses working at a university hospital in Korea. Anxiety symptoms were assessed using the anxiety subscale of the Hospital Anxiety and Depression Scale, with scores of 8 or higher indicating the presence of anxiety symptoms. Demographic, job-related, and psychological factors were compared according to the presence of anxiety. Logistic regression was conducted to identify factors associated with anxiety symptoms. Results: Two hundred and four (39.6%) participants had anxiety symptoms. Self-esteem and happiness were associated with a lower risk of anxiety symptoms, whereas burnout was associated with a higher risk of anxiety symptoms. Furthermore, being female, having a career of less than five years, and requiring counseling due to stress were associated with a higher risk of anxiety symptoms. Being younger, female, or a basic nurse; having a career of less than five years; partaking in shift work; experiencing job dissatisfaction; requiring counseling due to stress; being exposed to higher levels of burnout; and having lower levels of self-esteem and happiness were all found to be significantly correlated with anxiety symptoms. Conclusion These findings suggest that promoting self-esteem and happiness while reducing burnout may be beneficial in preventing and managing anxiety symptoms among hospital nurses.

Objective: The optimal sequence of adjuvant chemoradiation in the treatment of advanced endometrial carcinoma (EC) remains unclear. We sought to evaluate the outcomes of patients treated with chemoradiation in sandwich fashion (chemotherapy-radiotherapychemotherapy; CRC), versus those treated sequentially (chemotherapy-radiotherapy; CR) (radiotherapy-chemotherapy; RC), to determine if there is a survival advantaged associated with a particular treatment sequence. Methods: A multicenter retrospective analysis of patients with stage III and IV EC from 2000-2018 was conducted. Inclusion criteria were patients who had undergone comprehensive surgical staging/tumor debulking; followed by adjuvant chemoradiation. Differences in the frequencies of adverse events were evaluated using Pearson's χ 2 test. Progression free survival (PFS) and overall survival (OS) rates were calculated using Kaplan-Meier estimates. Results: Final analysis included 152 patients; 36.8% (n=56) CRC, 28.9% (n=44) CR, and 34.2% (n=52) RC. Histology included 44.0% endometrioid, 47.5% serous and 8.5% clear cell tumors. There was no difference in the frequency of histology (p=0.973), stage (p=0.143), cytoreduction status (p=0.932), or treatment delays (p=0.571) between adjuvant therapy sequences. The most frequent location of disease recurrence was abdomen. The median PFS favored CRC versus CR or RC (36-months vs. 22-months and 24-months, respectively) (p=0.038), as did the median OS (48-months vs. 28-months and 34-months, respectively) (p=0.003). CRC demonstrated superiority over CR and RC sequencing in terms 3-year PFS (55% vs. 34% and 37%, respectively) and 3-year OS (71% vs. 50% and 52%, respectively). Conclusions Adjuvant chemoradiation delivered in CRC sequence was associated with improvements in both PFS and OS compared to alternant therapy sequencing.

Despite significant regional and risk factor-related variations, the overall mortality rate in patients suffering from aneurysmal subarachnoid hemorrhage (SAH) remains high. Compared to ischemic stroke, which is typically irreversible, hemorrhagic stroke tends to carry a higher mortality, but patients who do survive have less disability. Technologies to monitor and treat complications of SAH have advanced considerably in recent years, but good long-term functional outcome still depends on prompt diagnosis, early aggressive management, and avoidance of premature withdrawal of support. Endovascular procedures and open craniotomy to secure a ruptured aneurysm represent some of the numerous critical steps required to achieve the best possible result. In this review, we have attempted to provide a contemporary, evidence-based outline of the perioperative critical care management of patients with SAH. This is a challenging and potentially fatal disease with a wide spectrum of severity and complications and an often protracted course. The dynamic nature of this illness, especially in its most severe forms, requires considerable flexibility in clinician management, especially given the panoply of available treatment modalities. Judicious hemodynamic monitoring and adaptive therapy are essential to respond to the fluctuating nature of cerebral vasospasm and the varying oxygen demands of the injured brain that may readily induce acute or delayed cerebral ischemia.

INTRODUCTIONUnderstanding baseline epidemiology of intussusception (IS) in different geographical settings is important for the safety assessment of rotavirus vaccines. This paper presents IS surveillance data from Singapore between 1997 and 2007, including the period between November 2005 and December 2007 when rotavirus vaccines (primarily Rotarix) were available to newborns in Singapore.

MATERIALS AND METHODSCase ascertainment, collection, analyses and presentation of IS data was done as per recommendations of the Brighton Collaboration Working Group. For estimating the IS incidence rate in infants, live births for the years of the study were used as denominators, while for incidence in children age <2 years, the expected numbers of infant deaths occurring between 1 and 2 years of age was deducted from the combined live births for the 2 years, to obtain the denominator.

RESULTSThe incidence of IS among children aged <1 year throughout this 10-year period was higher than the incidence of IS in children between 1 and 2 years of age. In 2005, 2006 and 2007, the incidence of IS per 100,000 was 39.9, 26.4 and 35.6 in children aged <1 year and 26.2, 23.8 and 28.7 in children <2 years.

CONCLUSIONThis IS surveillance study provides reassuring preliminary evidence that there is no increase in the incidence of IS in Singapore after the introduction of rotavirus vaccines (including Rotarix) in Singapore.

PURPOSE: To assess the prevalence of lower urinary tract symptoms (LUTS) and erectile dysfunction (ED) and the relationships between LUTS, ED, depression, and other factors in Korean men with type 2 diabetes mellitus (T2DM). METHODS: This cross-sectional study included 124 male patients with T2DM who attended a university hospital diabetes clinic between October 2010 and April 2012. Data were collected using structured interviews and chart reviews. LUTS were measured using the International Prostate Symptom Score (IPSS), ED using the five-item Korean version of the International Index of Erectile Function (IIEF), depression using the Center for Epidemiologic Studies Depression Scale, and glycosylated hemoglobin level from clinical data. RESULTS: The IPSS score was 9.2+/-6.6. The total IPSS scores indicated that 53.3% of the subjects had either moderate or severe symptoms. The mean IIEF score was 7.3+/-8.6, indicating the severity of ED to be mild, mild to moderate, moderate, and severe in 10.5%, 9.7%, 1.6%, and 66.9% of the participants, respectively. LUTS showed a significant negative correlation with ED (r=-0.26, P=0.003) and a significant positive correlation with depression (r=0.33, P<0.001). ED was negatively correlated with age (r=-0.44, P<0.001), duration of diabetes (r=-0.26, P=0.004), and depression (r=-0.24, P=0.008). CONCLUSIONS: LUTS and ED were found to have a high prevalence among Korean men with T2DM. More severe ED was associated with worse LUTS, whereas more severe depressive symptoms were found to be associated with more severe ED and LUTS.

Objectives: This study aimed to determine the motivating and hindering factors affecting the Infant and Young Child Feeding (IYCF) practices of Muslim mothers in select municipalities of Maguindanao. Methods: A pretested questionnaire was administered through face-to-face interviews conducted among 320 randomly selected Muslim mothers with a child aged 6-23 months. Results : Results revealed that prelacteal feeding was practiced by 16.6% of the Muslim mothers, giving mostly plain water. Solid/semi-solid foods were introduced at a mean age of 6.1 ± 1.4 months, with home-cooked lugao (porridge) (55.0%) and commercial baby food (31.3%) as the top foods introduced. The majority of Muslim mothers (82.5%) fed processed foods as complementary food to their children, including instant noodles (85.2%) and canned goods (51.5%). Conclusion The results revealed suboptimal practices in prelacteal feeding and the reliance on processed foods among Muslim mothers, with economic factors, availability, and convenience as motivating factors in complementary feeding practices. Challenges such as household duties, low milk output, and financial constraints hinder breastfeeding and nutritious food provision for infants and young children. The study reinforced the necessity for holistic strategies in IYCF promotion among Muslim mothers.
