Background: Docetaxel is one of the standard treatments for advanced non-small cell lung cancer. Docetaxel is usually administered in a 3-week schedule, but there is significant toxicity. In this phase II clinical study, we investigated the efficacy and safety of a 4-weekly schedule of docetaxel monotherapy, as first-line chemotherapy for advanced squamous cell carcinoma in elderly lung cancer patients. Methods: Patients with stage IIIB/ IV lung squamous-cell carcinoma age 70 or older, that had not undergone cytotoxic chemotherapy were enrolled. Patients received docetaxel $25mg/m^2$ on days 1, 8, and 15, every 4 weeks. Primary endpoint was the objective response rate (ORR). Secondary endpoints were progression-free survival (PFS), overall survival (OS), and toxicity profiles. Results: A total of 19 patients were enrolled. Among 19 patients, 17 were for evaluated efficacy and safety. In the intent-to-treat population, ORR and disease control rate (DCR) were 11.8% and 47.1%, respectively. In the response evaluable population, ORR was 16.7% and DCR was 66.7%. Median PFS and OS were 3.1 months and 3.3 months, respectively. There were three adverse grade 3/4 events. Grade 1 neutropenia was reported in one patient. Conclusion: Our data failed to demonstrate efficacy of a 4-weekly docetaxel regimen, in elderly patients with a poor performance status. However, incidence of side effects, including neutropenia, was lower than with a 3-week docetaxel regimen, as previously reported.

연구배경: 폐암의 발생은 접점 증가추세로 65세 이상환자가 전체 폐암의 50% 정도를 차지하지만, 잦은 만성 질환의 동반, 각종 장기의 기능저하로 수술, 방사선치료나 항암화학요법과 같은 적극적 치료를 감당하지 못할 것을 우려하여 적절한 치료를 받지 못하고 있어 노령 폐암환자의 임상적 특성의 분석을 통하여 향후 이들에 대한 대책수립하고자 본 연구를 시행하였다. 방 법: 1994년 9월부터 1998년 8월사이에 서울특별시립 보라매 병원에 입원하여 폐암으로 진단받은 환자 207명을 대상으로, 65세이상의 I군과 65세미만의 II군으로 분류하여 후향적 분석을 하였다. 결 과: 60대에서 36.2%로 가장 높은 발병률을 보였고, 65세 이상의 남자환자가 전체환자의 42%였다. I군에서 호흡곤란을 주소로 하는 환자가 유의하게 많았으나, 이외의 증상이나 병기, 조직학적 분류상두군간에 유의한 차이는 없었다. ECOG기준 활동도 3, 4인 환자가 II군의 12.9%에 비해 I군에서는 35.2%로 많았다. 소세포폐암의 치료는 두 군간에 차이가 없었으나, 비소세포폐암 환자는 II군의 35%에 비해 I군 환자의 74%가 보존적 치료만을 받았고, 수술이나 근치적 방사선치료를 받은 환자는 I군에서 14%에 불과하였다. 두 군간에 생존을 비교하면 I군의 중앙생존기간이 10개월로 II군의 17.4개월에 비해 떨어지지만, 보존적 치료외에 어떠한 치료라도 받았던 환자에서는 두군간에 차이를 보이지 않았다. 활동도, 병기, 조직학적 아형만이 다변량분석시 생존에 영향을 미치는 유의한 인자였고 연령은 생존과 무관한 인자였다. 결 론: 폐암은 노령환자의 질환이라고 할만큼 65세 이상에서 호발하며, 환자의 연령에 의해서 예후가 결정되는 것이 아니므로 노령환자라 하더라도 폐암에 대한 적극적 진단 및 치료가 필하다고 하겠다.

In general the prevalence of old people is high and frequently have multiple diseases and symtoms requiring treatment. The nature of illness in the elderly has to be faced, and drugs do have an important part in the treatment of that illness. The purpose of this study were to describe health status and medication, and to provide some basic data for elderly's health education, especially for the right medication. Body mass index, self perceived health status, activities of daily living, disease and experience of past operation were surveyed to recognize the 249 elderly's actual health status. The degree of the elderly's understanding the way of medication, experience of side effects, experience of drug combination and incidence of drug adverse reaction along with drug combination were examined for medication. The aged $women(BMI; 10.7\pm13.3\%)$ overweighed the aged $men(BMI; 4.0\pm10.4\%)$. $69.0\%$ of them recognized their health good. Their activities of daily living were diminished following by the age group(p=0.0068) and relationship with self perceived health status were very significant(p=0.0005). They(192 elderly) suffered from multiple disease such as $osteoarthritis(49.5\%)$, $hypertension(32.0\%)$, gastric $disorder(16.1%)$, $diabetes(14.6\%)$, $osteomalacia(10.9\%)$, cardiovascular $disease(9.9\%)$, senile $cataract(5.7\%)$, skin $rash(5.2\%)$, liver $disease(4.2\%)$, kidney $disease(3.6\%)$, spinal cord $problem(3.6\%)$, respiratory $disease(2.1\%)$ $tuberculosis(1.0\%)\;etc(1.0\%).$ $28.3\%$ of them replied that they had an operation for appendictis senile cataract, peptic ulcer, spinal cord problem, pleurisy, hemorrhoid and the rest. Most of $them(87.4\%)$ knew the way very well how to use drugs, and $21.6\%$ of the replied 171 elderly experienced adverse drug reaction. Drug compliance rate were $high(83.6\%)$. In our study 56.9% of the 167 elderly took several medicine together. And $18.9\%$ of the 95 elderly who did drug combination had an experience of drug interaction. One person kept average 5.5 kinds of drugs at home among 243 elderly. They kept $digestives(79.4\%)$, $ointments(68.7\%)$, $vitamins(59.7\%)$, $analgesics(59.7\%)$, cold $medicines(45.3\%)$ antiarthritic $drugs(33.3\%)$, health $foods(27.7\%)$, antihypertensive $drugs(25.1\%)$, anti peptic ulcer $drugs(24.7\%)$, $laxatives(19.8\%)$, $antacids(16.5\%),\;antibiotics(l6.5\%)$, hypoglycemic $agents(10.3\%)$, cardiac $stimulants(7.0\%)$, $diuretics(4.5\%)$, antiarrhythmic $drugs(4.9\%)$, anti anginal $drugs(4.1\%)$, $hypnotics(3.3\%)$, $etc(38.3\%)$. With this result, we ascertain that polypharmacy in the elderly caused by multiple disease is common, which lead to drug interaction. So our task is to educate elderly how to use drugs in order to maximize their efficiency and to minimize their adverse effects.

Background: More than half of cases for advanced non-small-cell lung cancer (NSCLC) occur in elderly patients with a median age at diagnosis of 70 years. The aim of our study was to examine the clinical features and prognostic factors contributing to mortality in elderly patients with advanced NSCLC. Methods: Following a retrospective review of clinical data, 122 patients aged 70 years and over with a histopathological diagnosis of locally advanced (stage IIIB, n=32) and metastatic (stage IV, n=90) NSCLC between 2005 and 2011 were enrolled. Results: The median age was 76 years (interquartile range, [IQR], 72-80 years), and 85 (70%) patients were male. Fifty-seven (46%) patients had never smoked, and 17 (19%) were in a malnourished state with a body mass index (BMI) of <$18.5kg/m^2$. The initial treatments included chemotherapy (40%) and radiotherapy (7%), but 57% of the patients received supportive care only. The 1-year survival rate was 32%, and the 3-year survival rate was 4%, with a median survival duration of 6.2 months (IQR, 2.5-15.3 months). Male gender (hazard ratio [HR], 2.2; 95% confidence interval [CI], 1.3-3.9; p=0.005), low BMI (HR, 2.3; 95% CI, 1.3-3.9; p=0.004), and supportive care only (HR, 1.9; 95% CI, 1.2-2.9; p=0.007) were independent predictors of shorter survival based on a Cox proportional hazards model. Conclusion: Elderly patients with advanced NSCLC had a poor prognosis, particularly male patients, those with a low BMI, and those who received supportive care only.

Background: The purpose of this study was to evaluate the long-term survival rates of very elderly (age ≥80) critically ill patients admitted to a medical intensive care unit (MICU) at a regional tertiary-care hospital in Korea. Methods: We retrospectively analyzed data from patients who survived after discharged from the MICU of our hospital. Survival rates at 90 days, 1 year, 2 years, and 3 years were assessed between patients age ≥80 and those age <80. Survival status was evaluated using the National Health Insurance Service data. Results: A total of 468 patients were admitted, 286 (179 males, 97 females; mean age, 70.18±13.2) of whom survived and were discharged soon after their treatment. Among these patients, 69 (24.1%) were age ≥80 and 217 (75.9%) were age <80. The 90-day, 1-year, 2-year, and 3-year survival rates of patients age ≥80 were significantly lower than those in patients age <80 (50.7%, 31.9%, 15.9% and 14.5% vs. 68.3%, 54.4%, 45.6%, and 40.1%, respectively) (p<0.01). The Kaplan-Meier survival curves showed significantly lower survival rates in patients age ≥80 than in those age <80 (p=0.001). Conclusion: The poor rates of long-term survival in very elderly (age ≥80) and critically ill patients admitted to an ICU should be considered while managing and treating them.

Background: Efficacy and safety of tiotropium bromide, a muscarinic receptor antagonist, in treatment of asthma have been reported. However, its effect on airway remodeling in chronic asthma of the elderly has not been clearly verified. The objective of this study was to investigate the effect of tiotropium and expression of muscarinic receptors as its related mechanism in an aged mouse model of chronic asthma with airway remodeling. Methods: BALB/c female mice age 6 weeks, 9 and 15 months were sensitized and challenged with ovalbumin (OVA) for three months. Tiotropium bromide was administered during the challenge period. Airway hyperresponsiveness (AHR) and pulmonary inflammation were measured. Parameters of airway remodeling, and expression levels of $M_2$ and $M_3$ receptors were examined. Results: Total cell with eosinophils, increased in the OVA groups by age, was decreased significantly after treatment with tiotropium bromide, particularly in the age group of 15 months. AHR and levels of interleukin (IL)-4, IL-5, and IL-13 were decreased, after tiotropium administration. In old aged group of 9- and 15-months-treated groups, hydroxyproline contents and levels of ${\alpha}$-smooth muscle actin were attenuated. Tiotropium enhanced the expression of $M_2$ but decreased expression of $M_3$ in all aged groups of OVA. Conclusion: Tiotropium bromide had anti-inflammatory and anti-remodeling effects in an aged mouse model of chronic asthma. Its effects seemed to be partly mediated by modulating expression $M_3$ and $M_2$ muscarinic receptors. Tiotropium may be a beneficial treatment option for the elderly with airway remodeling of chronic asthma.

Background: The most consistently identified mortality determinants for the new coronavirus 2019 (COVID-19) infection are aging, male sex, cardiovascular/respiratory diseases, and cancer. They were determined from heterogeneous cohorts that included patients with different disease severity and previous conditions. The main goal of this study was to determine if activities of daily living (ADL) dependence measured by Barthel's index could be a predictor for COVID-19 mortality. Methods: A prospective cohort study was performed with a consecutive sample of 340 COVID-19 patients representing patients from all over the northern region of Portugal from October 2020 to March 2021. Mortality risk factors were determined after controlling for demographics, ADL dependence, admission time, comorbidities, clinical manifestations, and delay-time for diagnosis. Central tendency measures were used to analyze continuous variables and absolute numbers (proportions) for categorical variables. For univariable analysis, we used t test, chi-square test, or Fisher exact test as appropriate (α=0.05). Multivariable analysis was performed using logistic regression. IBM SPSS version 27 statistical software was used for data analysis. Results: The cohort included 340 patients (55.3% females) with a mean age of 80.6±11.0 years. The mortality rate was 19.7%. Univariate analysis revealed that aging, ADL dependence, pneumonia, and dementia were associated with mortality and that dyslipidemia and obesity were associated with survival. In multivariable analysis, dyslipidemia (odds ratio [OR], 0.35; 95% confidence interval [CI], 0.17-0.71) was independently associated with survival. Age ≥86 years (pooled OR, 2.239; 95% CI, 1.100-4.559), pneumonia (pooled OR, 3.00; 95% CI, 1.362-6.606), and ADL dependence (pooled OR, 6.296; 95% CI, 1.795-22.088) were significantly related to mortality (receiver operating characteristic area under the curve, 82.1%; p<0.001). Conclusion: ADL dependence, aging, and pneumonia are three main predictors for COVID-19 mortality in an elderly population.

본 논문은 만성질환으로 응급실에 내원한 노인 환자의 응급의료 이용 변화 추이를 알아보고자 하였다. 2014년 1월 1일부터 2019년 12월 31일까지의 국가응급진료정보망 자료에서 응급실 퇴실 주 진단 상병코드가 8개 만성질환에 해당하는 환자를 선택하여 응급실 이용 현황 및 응급실 내원과 입원의 변화 추이를 살펴보았다. 2014년을 기준으로 만성질환으로 응급실을 내원한 노인 환자는 지속 증가하였고, 특히 85세 이상의 환자가 급격히 증가하였다. 만성질환별 응급실 내원 비율 변화추이에서는 대부분 질환에서 증가세를 보였고(P<0.001), 그 중 허혈성심장질환, 관절병증에서 높은 증가율을 보였으나 고지혈증은 전 연령에서 감소세를 보였다(P<0.001). 응급실 입원율 변화 추이에서는 고지혈증, 고혈압, 결핵을 제외한 만성질환에서 지속적으로 증가세를 보였다(P<0.001). 만성질환을 가진 노인 환자의 응급실 내원 및 입원율의 지속적인 증가는 응급의료자원의 점유 및 의료 소비량 증가 문제를 가속시킬 수 있는 원인으로 작용할 수 있으므로 적절한 만성질환 관리가 필요하다.

Coronavirus disease 2019 (COVID-19) has become a major health burden worldwide, with over 600 million confirmed cases and 6 million deaths by 15 December 2022. Although the acute phase of COVID-19 management has been established, the long-term clinical course and complications due to the relatively short outbreak is yet to be assessed. The current COVID-19 pandemic is causing significant morbidity and mortality around the world. Interestingly, epidemiological studies have shown that fatality rates vary considerably across different countries, and men and elderly patients are at higher risk of developing severe diseases. There is increasing evidence that COVID-19 infection causes neurological deficits in a substantial proportion to patients suffering from acute respiratory distress syndrome. Furthermore, lack of physical activity and smoking are associated with severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) susceptibility. We should therefore explore why lack of physical activity, smoking, etc causing a population more susceptible to SARS-CoV-2 infection, and mechanism involved. Thus, in this review article, we summarize epidemiological evidence related to risk factors and lifestyle that affect COVID-19 severity and the mechanism involved. These risk factors or lifestyle interventions include smoking, cardiovascular health, obesity, exercise, environmental pollution, psychosocial social stress, and diet.
