Sex differences in the factors that affect medical lethality in elderly suicide attempters

ObjectivesThis study aimed to identify sex differences in the factors that affect medical lethality in elderly suicide attempters.MethodsA total of 253 elderly suicide attempters and 351 middle-aged attempters (comparison group) who visited the emergency room at a general hospital were included. The sociodemographic and clinical characteristics of the patients were investigated. The Chi-squared test and logistic regression analysis were performed. And Spearman’s correlation coefficient was calculated.ResultsIn older males, the risk of high lethality was lower when attempting suicide due to the loss of family members [adjusted odds ratio (AOR): 0.08]. The risk increased as the intent to die became more certain (some AOR: 11.31, certain AOR: 28.75), and this association became more pronounced with age (rho middle-aged: 0.329; young-old: 0.387; old-old: 0.415). In older females, the risk was lower when employed (AOR: 0.28). The method of suicide attempt also affected lethality (agricultural chemicals AOR: 3.71; psychiatric medication AOR: 0.31).ConclusionSex differences in the factors that affect medical lethality were identified among elderly suicide attempters. In particular, medical lethality can be predicted by the degree of suicide intention in older males. These findings will help to establish more efficient preventive strategies with specific targets

THE EFFECTS OF WEARING ROLLER SHOES ON GROUND REACTION FORCE CHARACTERISTICS DURING WALKING

Roller shoes have become increasingly popular among children and it features retractable wheels which allowing the user to walk or roll without changing the footwear. Maintaining balance during forward walking with roller shoes is not an easy task. To prevent falling backward, the user needs to lock the knees and tighten the ankles and thighs while the upper body is slightly leaning forward. Constant walking with roller shoes forces the user to walk in a manner much different from normal gait. Prolonged exposure to un-natural stresses on human body forces our body to evolve by strengthening those incorrect, and temporary functions (Clement et aI., 1981). For children, the chronic stress may lead to serious injuries in the lower extremity later in life. If any potential' of injury exists in a movement it is critical to examine the associated forces that may lead to injury. To the best of our knowledge, the effects of wearing roller shoes on ground reaction forces (GRF) characteristics have rarely been studied, especially in the youth population. Thus, the purpose of this study was to compare GRF characteristics during walking wearing jogging and roller shoes

Fever-Induced QTc Prolongation and Ventricular Fibrillation in a Healthy Young Man

Long QT syndrome is associated with lethal tachyarrhythmia that can lead to syncope, seizure, and sudden death. Congenital long QT syndrome is a genetic disorder, characterized by delayed cardiac repolarization and prolongation of the QT interval on the electrocardiogram (ECG). Type 2 congenital long QT is linked to mutations in the human ether a go-go-related gene (HERG). There are environmental triggers of adverse cardiac events such as emotional and acoustic stimuli, but fever can also be a potential trigger of life-threatening arrhythmias in long QT syndrome type 2 patients. Herein, we report a healthy young man who experienced fever-induced polymorphic ventricular tachycardia and QT interval prolongation

A Pulmonary Nodule due to Pulmonary Infarction Diagnosed by Video-Assisted Thoracoscopy

We report a pulmonary infarction in 68-year-old man who was referred for an asymptomatic pulmonary nodule in chest radiography. Computed tomography (CT), positron emission tomography (PET), and transthoracic needle aspiration suggested suspicion for malignancy. Video-assisted thoracoscopic surgery (VATS) was performed for histologic diagnosis. Our case is a pulmonary nodule due to pulmonary infarction diagnosed by VATS in Korea

Inflammatory pseudotumor of eyelid: a probable IgG4-related sclerosing disease clinically mimicking eyelid pilomatrixoma

It is characterized by stromal sclerosis and an infiltration of mass-forming lymphoplasmic cells containing many IgG4-positive plasma cells. Although ocular adnexal tissue involvement has been increasingly reported, a focal nodular sub-brow mass is not typical in an IgG4-SD presentation. We report a rare case of probable ocular adnexal IgG4-SD that clinically mimicked eyelid pilomatrixoma. Case presentation A 42-year-old woman presented with a nodular mass in her left sub-brow area. The initial clinical impression of her lesion was eyelid pilomatrixoma. However, the final pathologic diagnosis was IgG4–SD, but extranodal marginal zone B-cell lymphoma could not be excluded. The patient underwent testing to determine tumor malignancy and systemic IgG4-SD involvement. Laboratory testing showed normal IgG and IgG4 serum levels and imaging revealed no remarkable findings. Oral prednisolone was administered and slowly tapered to manage the possible remnant lesion and to prevent disease recurrence. Two years after initiating therapy, there was no evidence of relapse. The patient is under close surveillance for signs of recurrence, systemic involvement, and potential malignant transformation. Conclusions We found an unusual case of probable ocular adnexal IgG4-SD, which presented as a unilateral restricted mass involving the sub-brow area. Although the mass was surgically removed, systemic steroid treatment and long-term surveillance were initiated due to the possibility of recurrence, the potential association with systemic disease, and the potential development of extranodal mucosa-associated lymphoid tissue (MALT) lymphoma

Salivary flow rate and the risk of cognitive impairment among Korean elders: a cross-sectional study

Background Salivary function has been suggested to be associated with cognitive impairment. However, the effect of salivary flow rate (SFR) on cognitive impairment remains unclear. This study aimed to investigate whether SFR is associated with cognitive impairment among Korean elders. Methods This cross-sectional study included 649 elders aged 65 and older in the Korean community-dwelling population. Cognitive impairment was assessed using the Mini-Mental Status Examination. Unstimulated SFR was measured and dichotomized. Denture status, age, sex, education level, smoking, drinking, diabetes, hypertension, and obesity were considered confounders. Multivariable logistic regression analysis was applied to assess the adjusted association. Stratified analysis by sex and denture status was performed to clarify the effect modification. Results Participants without cognitive impairment showed a higher SFR level than those with cognitive impairment (0.81 mL/min for non-cognitive impairment versus 0.52 mL/min for cognitive impairment, p < 0.001). After controlling for confounders, participants with low SFR (< 0.3 mL/min) were more likely to have cognitive impairment by 1.5 times than participants with normal SFR (odds ratio [OR] = 1.5, confidence interval [CI] = 1.05–2.10). The association of low SFR with cognitive impairment was higher in women and dentate participants: about 10% higher in women (OR = 1.63, CI = 1.07–2.50) and about 22% higher in dentate participants (OR = 1.82, CI = 1.41–2.90). Conclusions Salivary flow rate is independently associated with cognitive impairment among Korean elders. The association was modified in females and dentate elders. Physicians and dentists should consider low SFR and cognitive impairment as a risk factor between them in clinics.This study had financial support through HDK from the National Research Foundation (NRF) of the Ministry of Science and ICT, Korea (NRF2017M3A9B6062986) and the Korea Centers for Disease Control and Prevention (2018P330400) that did not do anything for the submitted wor

Factors associated with satisfaction with pediatric emergency department services in Korea: analysis of Korea Health Panel Data 2010 to 2012

Objective We aimed to investigate the factors related to satisfaction with the pediatric emergency department service in Korea. Methods This study examined data from the Korea Health Panel Data from 2010 to 2012. Pediatric patients who visited the emergency department at least once between 2010 and 2012 in Korea were included. Data were collected on patient satisfaction with the emergency department service, and factors related to the patient characteristics, emergency department service process, and medical institution. We compared the dissatisfied and satisfied groups, and calculated the odds ratios for satisfaction according to each variable. Results A total of 1,505 emergency department visits from 947 pediatric patients during the 3-year period were analyzed. We estimated that about 79.5% of patients in the population were satisfied. The odds of expressing satisfaction were higher among males than in females, and among patients who were hospitalized after emergency department treatment compared to those who were transferred to another hospital. Conversely, the odds of expressing satisfaction were lower among patients who had a chronic disease, a financial source other than National Health Insurance, experienced hospitalization within 1 year. Conclusion Our study results might be helpful for establishing a satisfactory pediatric emergency medical service system. In the future, further prospective studies evaluating the causal relationships between the relevant factors and patient satisfaction are warranted
