Electroconvulsive therapy (ECT) is indicated for various mental disorders (e.g., major depressive disorder, schizophrenia, and bipolar disorder) and the behavioral and psychological symptoms of dementia in elderly patients. Furthermore, ECT is a useful first-line treatment in emergency and crisis situations such as suicide risk, violent behavior, catatonia, and food refusal, which are more frequent in elderly patients. ECT is also effective in the treatment of the motor symptoms of neurological disorders, such as Parkinson's disease and Huntington's disease. Due to the high risk of various physical diseases, the comorbid physical conditions of elderly patients should be individually controlled to optimize ECT treatment. Compared to young adults, in elderly patients the seizure threshold is higher, the seizure duration is shorter, and the anesthetic dose is lower. On the contrary, the response rate in the elderly is both faster and higher. Considering potential cognitive decline and the prevention of further deterioration of cognitive function in elderly patients, in the absence of significant comorbidities, twice weekly sessions and right unilateral electrode placement with a lower seizure threshold and less cognitive effect are preferred to bilateral electrode placement, which has a high risk of adverse cognitive effects. After an acute course of ECT, continuation and maintenance of ECT, combined with prescription of therapeutic drugs, may prevent possible relapse or recurrence of mental disorders. In conclusion, ECT can be used to treat mental disorders in elderly adults, with safety and effectiveness comparable to that in young adults.

Purpose: As the rate of endoscopic resection for early gastric cancer (EGC) has increased in patients with comorbid diseases, it is necessary to elucidate the efficacy of endoscopic submucosal dissection (ESD) for EGC in patients with comorbidities. This study aimed to analyze the clinical outcomes of ESD for EGC in patients with comorbidities. Materials and Methods: A total of 969 patients with 1,015 lesions who underwent ESD for EGC at Seoul National University Hospital between 2010 and 2014 were analyzed. The short- and long-term clinical outcomes were evaluated according to the comorbidity status. Results: Comorbidities were observed in 558 patients (57.6%). The comorbidity group had a higher proportion of patients using antithrombotic agents (29.5% vs. 0.9%; P<0.0001). Although procedure-related complications (bleeding and perforation) were not significantly different between the two groups, the length of hospital stay was significantly longer (1.8 vs. 1.4 days, P=0.023), while survival was significantly shorter in the comorbidity group (5-year overall survival rate: 90.5% vs. 97.2%, P<0.0001; 5-year disease-specific survival rate: 97.9% vs. 100%, P=0.018; 5-year disease-free survival rate: 83.4% vs. 89.2%, P=0.007). Conclusions: Gastric ESD can be performed in patients with comorbidities without increasing the risk of complications.

Patients with Pressure injuries (PIs) may have pain and discomfort, which results in poorer patient outcomes and additional cost for treatment. This study was a part of larger research project that aimed at prediction modeling using a big data. The purpose of this study were to describe the characteristics of patients with PI in critical care; and to explore comorbidity and diagnostic and interventive procedures that have been done for patients in critical care. This is a secondary data analysis. Data were retrieved from a large clinical database, MIMIC-III Clinical database. The number of unique patients with PI was 2,286 in total. Approximately 60% were male and 68.4% were White. Among the patients, 9.9% were dead. In term of discharge disposition, 56.2% (33.9% Home, 22.3% Home Health Care) where as 32.3% were transferred to another institutions. The rest of them were hospice (0.8%), left against medical advice (0.7%), and others (0.2%). The top three most frequently co-existing kinds of diseases were Hypertension, not otherwise specified (NOS), congestive heart failure NOS, and Acute kidney failure NOS. The number of patients with PI who have one or more procedures was 2,169 (94.9%). The number of unique procedures was 981. The top three most frequent procedures were 'Venous catheterization, not elsewhere classified,' and 'Enteral infusion of concentrated nutritional substances.' Patient with a greater number of comorbid conditions were likely to have longer length of ICU stay (r=.452, p<.001). In addition, patient with a greater number of procedures that were performed during the admission were strongly tend to stay longer in hospital (r=.729, p<.001). Therefore, prospective studies focusing on comorbidity; and diagnostic and preventive procedures are needed in the prediction modeling of pressure injury development in ICU patients.

Background: Acute respiratory distress syndrome (ARDS) is related to high mortality and morbidity. There are no proven therapeutic measures however, to improve the clinical course of ARDS, except using low tidal volume ventilation. Metformin is known to have pleiotropic effects including anti-inflammatory activity. We hypothesized that pre-admission metformin might alter the progress of ARDS among intensive care unit (ICU) patients with diabetes mellitus (DM). Methods: We performed a retrospective cohort study from January 1, 2005, to April 30, 2005 of patients who were admitted to the medical ICU at Seoul National University Hospital because of ARDS, and reviewed ARDS patients with DM. Metformin use was defined as prescribed within 3-month pre-admission. Results: Of 558 patients diagnosed with ARDS, 128 (23.3%) patients had diabetes and 33 patients were treated with metformin monotherapy or in combination with other antidiabetic medications. Demographic characteristics, cause of ARDS, and comorbid conditions (except chronic kidney disease) were not different between metformin users and nonusers. Several severity indexes of ARDS were similar in both groups. The 30-day mortality was 42.42% in metformin users and 55.32% in metformin nonusers. On multivariable regression analysis, use of metformin was not significantly related to a reduced 30-day mortality (adjusted ${\beta}-coefficient$, -0.19; 95% confidence interval, -1.76 to 1.39; p=0.816). Propensity score-matched analyses showed similar results. Conclusion: Pre-admission metformin use was not associated with reduced 30-day mortality among ARDS patients with DM in our medical ICU.

본 논문에서는 우울증과 관상동맥 질환의 연관성에 대해 병태생리학적 기전을 중심으로 고찰하였다. 현재까지 선행 연구들을 통해 제시된 주요 병태생리학적 기전으로는 우울증에서의 증가된 혈액 응고 경향, HPA 축 기능 및 ANS 조절 이상, 상승된 염증 반응 상태 등과 더불어 관상동맥 질환과 우울증이 공통된 유전적 위험 인자를 공유하고 있을 가능성 등이 있다. 혈액 응고와 관련되어서는 혈소판의 활성 및 반응성 증가, 혈관 내피 기능 이상, 혈액 응고 인자의 증가 등이 구체적인 병리 기전으로 제시 되었으며, HPA 축 및 ANS 기능 이상과 관련되어서는 혈장내 카테콜라민의 증가와 이와 연관된 심박수 증가 및 심박 변이성의 감소, 기타 혈역학적 스트레스의 증가 등으로 인한 부정맥 및 죽상경화증의 촉진이 주요한 기전으로 제시되었다. 또한 CRP 등과 같은 염증 표지자 연구를 통해 우울증에서의 증가된 염증 반응이 죽상경화증이나 혈전 형성과 관계 되어있을 가능성 역시 제시되었다. 하지만 역으로 관상동맥 질환과 우울증의 동반 이환율이 높다는 사실은 잘 알려져 있음에도 불구하고 관상동맥 질환에서의 어떤 병태생리적 변화가 우울증의 발병 및 경과와 관련되어 있는지에 대해서는 체계적인 연구가 매우 적은 것이 사실이다. 이 이외에도 우울증과 관상동맥 질환 외의 제3의 요인 즉, 유전적 위험 인자가 두 질환에 선행함을 제시하여 우울증과 관상동맥 질환이 공통된 유전적 취약성을 공유하고 있을 가능성을 제기한 연구들도 있다. 그 밖에도 우울증과 대사 증후군과의 연관성에 기반한 연구나 ${\Omega}$-3 지방산, homocystein 수준에 주목한 일부 연구들이 존재하며, 관상동맥 질환을 가진 환자는 뇌혈관에도 죽상경화증이 있을 가능성이 높고 이로 인해 뇌의 특정 부위에 혈류장애가 있을 가능성이 높아서 이것이 혈관성 우울증을 야기할 가능성이 있다는 보고를 한 연구들도 있다. 우울증이 관상동맥 질환의 발생 및 경과에 부정적인 영향을 끼친다는 많은 연구 결과들은 우울증과 관상동맥 질환의 원인적 연관성에 대한 연구를 지속적으로 촉진시키고 있다. 하지만 우울증이라는 대상 질환 자체의 이질성과 관상동맥 질환을 가지고 있는 환자들은 대부분 항응고제 등의 약물을 투여하고 있다는 사실 등이 병태생리 규명 연구에 어려움을 주고 있는 것이 사실이다. 우울증과 관상동맥 질환의 병태생리적 연관성에 대한 지속적이고 다각적인 연구는 향후 관상동맥 질환 환자에서의 우울증의 중요성을 치료자에게 인식시키는 계기가 될 수 있으며 더 나아가 관상동맥 질환의 치료 예후의 개선으로 이어질 수 있는 통로를 제공할 것이다.

Physical inactivity may an important outcome in the prognosis of breast cancer. Physical activity levels decrease significantly for breast cancer patients following the treatment and remain low after oncology treatment is completed. The aim of this study was to determine physical activity levels and to examine associations among physical activity, comorbidity, functional capacity, peripheral muscle strength, and psychosocial status in breast cancer patients. Forty breast cancer survivors were included in this study. Demographic and clinical characteristics were recorded. Physical activity was assessed with a short form of the International Physical Activity Questionnaire (IPAQ). We defined comorbid diseases according to the Charlson Comorbidity Index (CCI). Functional capacity was evaluated with a six-minute walk test (6MWT). Peripheral muscle strength was measured for quadriceps femoris muscle with a hand-held dynamometer. Psychosocial status was measured with the Hospital Anxiety Depression Scale (HADS). Forty percent of patients were inactive. The IPAQ total score was significantly related with quadriceps muscle strength (r=0.492; p<0.001) and HADS depression score (r=0.341; p<0.05). Marked correlations were also observed between IPAQ walking score and quadriceps muscle strength (r=0.449; p<0.001), HADS depression score (r=0.341; p<0.05), and CCI (r=-0.433; p<0.001). The CCI score was also markedly associated with quadriceps muscle strength (r=-0.413; p<0.001). 6MWT distance was not significantly correlated with any of the parameters. Regression analyses revealed that psychosocial status and peripheral muscle strength were significant predictors of physical activity estimated with the IPAQ short form and when combined, they explained 35% of the variance. Comorbidities, peripheral muscle strength and psychosocial status partially explain the variability of physical activity level in breast cancer survivors. These results suggest that physical inactivity contributes to worsening health in breast cancer survivors.

Hypertension is one of the most common chronic diseases and it causes cardiovascular and cerebrovascular disease. While antihypertensive drug use increased, it took 15% of national health insurance drug expenditure. This study aimed to examine the pattern of antihypertensive drug prescription using National Health Insurance claims database and compare it with recommendations of Korea Hypertension Treatment Guidelines. Among the antihypertensive drugs, calcium channel blocker(64.4%) was most commonly prescribed class, and diuretics(44.6%), angiotensin II receptor blocker(33.3%), angiotensin converting enzyme inhibitor(11.7%) was followed. Approximately 81% of antihypertensives prescription were without cardiovascular or cerebrovascular disease, and among the comorbid conditions, diabetes(10.7%) was most common. calcium channel blocker(62.3%) was mostly prescribed class for hypertension with angina pectoris, angiotensin receptor blocker(45.3%) with myocardial infarction, diuretics(70.2%) and calcium channel blocker(49.5%) with congestive heart failure. For Hypertension with cerebrovascular disease, calcium channel blocker(68.0%) and angiotensin receptor blocker(43.3%) were prescribed mainly. When it comes to diabetes, calcium channel blocker(57.2%) was still mostly prescribed and angiotensin receptor blocker(45.9%) followed. But in hospitals and tertiary hospitals, angiotensin receptor blocker(65.7, 66.1%) was mostly prescribed for the patients with diabetes. For Hypertension with chronic renal disease, angiotensin receptor blocker(59.5%), calcium channel blocker(56.5%), diuretics(54.6%) were mainly used. Average number of classes per prescribing was $1.89{\pm}0.89$ class, average days per prescribing was $33{\pm}19$ day. Among the hypertension without comorbidity, 40.5% of prescription was monotherapy and 58.8% of polytherapy included diuretics. Among the outpatient prescriptions, calcium channel blocker was the most commonly used class, and the prescription pattern in clinic did not closely followed recommendations of Hypertension Treatment Guidelines.

Purpose: This study was conducted to investigate the characteristics of drug induced anaphylactis and anaphylactic shock in patients who were admitted to the emergency department Methods: We retrospectively collected the data on patients with drug induced anaphylaxis and who were admitted to the emergency department from January 2001 to June 2009. The study group was divided into the non-shock and shock groups according to whether the systolic blood pressure more than 90mmHg. The initial demographic data, the causes of drug-induced anaphylaxis, the clinical manifestations, the treatment and the prognosis were reviewed for 72 patients. Results: The mean age of the study subjects was $47.9P{\pm}14.2$ years old and there were 40 male patients and 32 female patients. There were 26 patients in the non-shock group and 46 in the shock group. The mean age was older in the shock group than in the non-shock group ($51.5{\pm}15.1$ vs $42.5{\pm}10.6$, p-0.002). A history of drug allergy was more common in the shock group, but no difference was found for the comorbid chronic diseases between the two groups. Radio-contrast media was the most common cause, followed non-steroidal anti inflammatory drugs and antibiotics, but there is no difference in the causes between the two groups. The symptoms of cyanosis, syncope, sweating and dizziness were more frequently manifested in the shock group. The administration of intravenous fluid and injection of subcutaneous epinephrine at the emergency department were more frequent in the shock group than in the non-shock group. Conclusion: For the patients who were admitted to the emergency department with drug induced anaphylaxis, the mean age was older and the symptoms of cyanosis, syncope, sweating, dizziness were more frequent in the anaphylactic shock patients than in the non-shock group. More treatments were given at the emergency department to the anaphylactic shock patients.
