Less frequent body weight gain in elderly type 2 diabetic patients treated with glimepiride

Background:   The purpose of the present paper was to study the effect of a new sulfonylurea, glimepiride, which has an extra-pancreatic action that improves insulin resistance, on glycemic control and body weight gain in elderly patients with type 2 diabetes mellitus (DM).
Methods:   Thirty-seven type 2 diabetic patients being treated with either gliclazide or glibenclamide were switched to glimepiride for 6 months and clinical parameters were compared between elderly (≥ 65 years old, n  = 9) and non-elderly (< 65 years old, n  = 28) patients.
Results:   There was no significant difference between the two groups in baseline characteristics, or in changes in fasting plasma glucose (FPG) and HbA1c. For body weight change, however, none of the elderly patients (0/9) exhibited an increase, but 9 of 28 (32%) non-elderly subjects showed body weight gain ( P  < 0.05).
Conclusions:   Body weight gain with glimepiride treatment is less frequent in elderly patients with type 2 DM than in non-elderly patients with the disease. These data together with the recent increase in obese elderly patients with diabetes suggest that glimepiride is recommended for treatment of type 2 diabetes in this age group.     

不同年龄冠状动脉旁路移植术患者的代谢性危险因素特征分析

目的探讨不同年龄行冠状动脉旁路移植术(CABG)的冠心病患者代谢性危险因素特征。方法回顾性分析199例行CABG的冠心病患者的临床资料,根据年龄分为中青年组(年龄34～65岁,124例)和老年组(年龄≥65岁,75例),又根据冠状动脉病变程度分为多支病变亚组(病变支数≥3支)和非多支病变亚组(病变支数<3支),比较两组及亚组的代谢性危险因素特征。结果(1)中青年组高密度脂蛋白胆固醇(HDL-C)水平低于老年组,体质指数(BMI)、舒张压(DBP)高于老年组(均为P<0.05);老年组血肌酐(Cr)水平、高血压患病比例高于中青年组(均为P<0.05)。(2)中青年多支病变亚组空腹血糖(FPG)(7.21±3.44)mmol/L、DBP(79±10)mm Hg高于老年多支病变亚组(6.26±1.41)mmol/L、(75±11)mm Hg(P=0.034、0.03);HDL-C(1.07±0.26)mmol/L低于老年多支病变亚组(1.19±0.26)mmol/L(P=0.011)。(3)中青年非多支病变亚组的BMI、DBP高于老年组(均为P<0.05)。结论与老年组相比,低HDL-C、高BMI、高DBP是中青年冠心病CABG患者的代谢特征;高FPG是中青年冠心病多支病变CABG患者的代谢特征。

Bone lesions in elderly multiple myeloma

We investigated the incidence of bone lesions in elderly cases of multiple myeloma (MM) and the course of those lesions, and also evaluated the relationships of skeletal symptoms with prognostic factors, and prognosis. The subjects were 146 patients, aged 65 years or more (median age 74, range 65-97 year), who were admitted to 11 institutions between January, 1988 and December, 1997. They consisted of 64 men and 82 women. The disease type was IgG type in 88 patients, IgA type in 37 patients, Bence-Jones (BJ) type in 17 patients, IgD type in three patients, and non-secretory type in one patient. Bone lesions in elderly MM patients were compared with those in 65 non-elderly MM patients. Skeletal symptoms were noted in 104 patients, and bone pain in 75 patients at the time of diagnosis. The bone lesions were evaluated as only osteolytic lesions in 26 patients, osteolytic lesions + osteoporosis in 23 patients, only osteoporosis in 2 patients and pathologic bone fractures in 53 patients. The occurrence rate of osteoporosis plus osteolytic lesion was higher in elderly patients (63.5%) than that in non-elderly patients (NE-MM group) (28.3%) (p < 0.0001). The bone lesions were most often observed in lumbar vertebrae (58.7%), cranial bone (56.7%), thoracic vertebrae (40.4%) and ribs (27.9%). The occurrence rate of bone lesion in lumbar vertebrae was higher in elderly patients (58.7%) than that in non-elderly patients (22.6%) (p < 0.0001). The life activities were limited in 71 patients because of the bone lesions. The relationship between the prognostic factors of MM and bone lesions was evaluated. There was a significant difference in the serum Ca level between patients with and without bone pain (P < 0.0001) and between those with and without pathologic bone fracture (P < 0.01). There was a significant difference in the appearance rate of plasma cells in the bone marrow between the patients with and without bone lesions (P < 0.05), between those with and without bone pain (P < 0.01), and between those with and without pathologic fracture (P < 0.05). There was a significant difference in the serum beta 2-microglobulin level between the patients with and without bone pain, and between those with and without pathologic fracture. There were no significant differences in survival times between elderly MM patients with and without bone lesions, bone pain and pathological bone fractures, while significant differences of survival times were found between non-elderly MM patients with and without bone lesions, bone pain and pathological bone fractures (P < 0.05, each). These data suggest that there are some differences in bone lesions between elderly and non-elderly MM patients.     

Osteoporotic hip fractures in non-elderly patients: relevance of associated co-morbidities

Osteoporotic hip fractures (OHF) are not limited to elderly; however, studies in non-elderly are scarce. Thus, the aim of this study was to evaluate co-morbidities in non-elderly patients with OHF in a Community Teaching Hospital. All hospitalizations due to OHF during a 3-year period in a Community Teaching Hospital were retrospectively evaluated for co-morbidities, and patients 18-64?years old were compared with those ≥65?years old. Of all hospitalizations, 232 (0.73%) were due to hip fractures, and 120/232 (51.7%) patients had OHF. The comparison of the 13 (10.8%) OHF patients <65?years old (47.3?±?9.7?years) with 107 (89.2%) ≥65?years old (80.4?±?7.7?years) revealed a male predominance (61.5 vs. 27.1%, P?=?0.022) and a distinct ethnic distribution with a lower proportion of Caucasians in the former (61.5 vs. 86.9%, P?=?0.033). Moreover, non-elderly OHF patients had higher frequencies of insulin-dependent DM (38.5 vs. 3.7%, P?=?0.001) and alcoholism (38.5 vs. 4.7%, P?=?0.001) than aged patients. In contrast, rates of age-related co-morbidities such as stroke (7.7 vs. 18.7%, P?=?0.461), heart failure (23.1 vs. 14.0%, P?=?0.411), and dementia (7.7 vs. 15.9%, P?=?0.689) were comparable in both groups. Logistic regression analysis demonstrated that insulin-dependent DM (OR?=?25.4, 95% CI?=?4.7-136.8, P?相似文献   

Problems and therapeutic strategy for emergency operation of the abdomen in the aged

AIM: To study the problems and therapeutic strategies for emergency abdominal operations in elderly patients by comparing aged and non-aged who underwent an emergency operations for abdominal diseases. MATERIALS AND METHODS: The patients were divided into two groups: those 70 years old or more (85 cases, elderly) and those under 70 years old (228 cases, non-elderly). The type of disease, preoperative complications, postoperative course and outcome of main diseases such as ileus and perforation peritonitis were investigated. RESULTS: Regarding emergency diseases in the aged group, ileus, peritonitis and acute appendicitis were frequently found, in that order, and accounted for 79% of the cases. Incarceration of hernia was more frequently found than in the non-elderly group. On the contrary, acute appendicitis was more frequently found in the non-elderly group. Preoperative complications were found in 46 cases (54%), and were most prevalent in hypertension, cardiac diseases, and diabetes mellitus in this order. In the non-elderly group, preoperative complications were found in 59 cases (26%). Postoperative complications were found in 52 cases (61%) in the elderly group and in 21 (9%) in the non-elderly group. Respiratory complications were found most frequently, and were seen in 32% of the elderly cases. Respiratory complications were significantly more frequent in the elderly group than in the non-elderly group. Death following the operation was found in 9% in the aged group which was mostly due to ileus and peritonitis. CONCLUSION: With regard to the acute abdominal diseases in the elderly patients, both diagnosis and indications of surgery for ileus and peritonitis should be adequately done. Preparation for postoperative respiratory complications and cardiovascular diseases might help to save lives of the elderly.

Hepatocellular carcinoma in extremely elderly patients： An analysis of clinical characteristics, prognosis- and patient survival

AIM:To identify the clinical and prognostic features ofpatients with hepatocellular carcinoma (HCC) aged 80years or more.METHODS:A total of 1310 patients with HCC wereincluded in this study.Ninety-one patients aged 80 yearsor more at the time of diagnosis of HCC were defined asthe extremely elderly group.Two hundred and thirty-fourpatients aged≥50 years but less than 60 years wereregarded as the non-elderly group.RESULTS:The sex ratio (male to female) wassignificantly lower in the extremely elderly group (0.90:1)than in the non-elderly group (3.9:1,P<0.001).The positive rate for HBsAg was significantly lower in theextremely elderly group and the proportion of patientsnegative for HBsAg and HCVAb obviously increased inthe extremely elderly group (P<0.001).There wereno significant differences in the following parameters:diameter and number of tumors,Child-Pugh grading,tumor staging,presence of portal thrombosis or ascites,and positive rate for HCVAb.Extremely elderly patientsdid not often receive surgical treatment (P<0.001) andthey were more likely to receive conservative treatment(P<0.01).There were no significant differences insurvival curves based on the Kaplan-Meier methods incomparison with the overall patients between the twogroups.However,the survival curves were significantlyworse in the extremely elderly patients with stage Ⅰ/Ⅱ,stage Ⅰ/Ⅱ and Child-Pugh grade A cirrhosis in comparisonwith the non-elderly group.The causes of death did notdiffer among the patients,and most cases died of liver-related diseases even in the extremely elderly patients.CONCLUSION:In the patients with good liver functionsand good performance status,aggressive treatment forHCC might improve the survival rate,even in extremelyelderly patients.     

Percutaneous transluminal coronary angioplasty in patients over the age of 65 years.

PTCA performed in 672 patients (646 patients < 65 years and 26 patients > or = 65 years) from March 1986 to September 1990 consisting of 619 males and 53 females are being discussed for the purpose of comparison of the results between patients in the < 65 years and > or = 65 years age groups. It was found that diabetes mellitus (50 vs 24.4.%, P < 0.01), obesity (46.1 vs 26%, P < 0.05), and hyperlipidaemia (66 vs 37.1%, p < 0.01) had a higher incidence among the elderly. Of the total 1047 lesions observed, 662 lesions in the < 65 years age group and 37 lesions in the > or = 65 years age group were dilated by PTCA (1.02 lesions/patient and 1.4 lesions/patient respectively). The lesion morphology showed higher degree of irregular contour in the < 65 years age group (23.6 vs 8.1%, p < 0.05), though the number of lesions with PTCA attempted in all age groups were almost similar. Major complications included one MI (3.8%) and two deaths (7.6%) in the > or = 65 years age group. During followup (mean duration: 8.2 months > or = 65 years and 13.5 months < 65 years age group) significantly higher percentage of patients < 65 years were asymptomatic when compared to elderly (50.2 vs 15.4% p < 0.05). Angina status was same more often in the elderly (23.1 vs 2.8% p < 0.01). The cumulative rate for repeat PTCA was similar for elderly and younger patients.

Combined ERCP and EUS in One Session Is Safe in Elderly Patients When Compared to Non-elderly Patients: Outcomes in 206 Combined Procedures

Aims

Combined ERCP/EUS is becoming common. Combined procedures are frequently performed in elderly patients. We hypothesized that combined ERCP/EUS is equally safe in elderly patients when compared to non-elderly patients.

Methods

This was a retrospective single-center study comparing outcomes in elderly and non-elderly patients undergoing combined ERCP/EUS.

Results

A total of 206 patients were included. Mean age was 65 years (M:F 113:93); 99 were <65 years and 107 were >65. Indications included: jaundice (51 %), abnormal imaging (17 %), pancreatic tumor (11 %), abdominal pain (5 %), stent placement/change (5 %), acute or chronic pancreatitis (5 %), other (6 %). Fine needle aspiration was performed in 134 (65 %) procedures. Malignancy was identified in 142/206 (69 %) patients. Mean Charlson Comorbidity Index (CCI) was 7.5 (range 0–22). Among patients <65 years old there were no immediate adverse events. Long-term adverse events in patients <65 (within 30 days) included cholangitis (1), increasing abdominal pain (4), post-ERCP pancreatitis (3), nausea/vomiting (1), increasing fatigue (1), and increasing jaundice (1). A subgroup analysis among geriatric patients (>65) was performed. Mean CCI was 8.2 (range 0–22). There was one immediate adverse event of non-sustained ventricular tachycardia in a 76-year old. Long-term adverse events included increasing fatigue (1), nausea/vomiting (2), increasing abdominal pain (2), urosepsis (1), fever (2) and dehydration (1). There were no statistically significant differences in outcomes in elderly compared to non-elderly patients. Elderly patients had higher CCI scores (p = 0.04).

Conclusion

Combined ERCP/EUS in one session is safe in the general population and elderly patients, with no more adverse events than in non-elderly patients.     

Treatment of small cell lung cancer in the elderly: the progress and limitation of chemotherapy]

In order to assess the progress and limitation of chemotherapy in the treatment of small cell lung cancer in the elderly, we analyzed 218 patients who had entered into protocol studies between 1982 and 1990. Among those, there were 101 elderly patients (age of greater than or equal to 66 years) and 117 non-elderly patients (age of less than or equal to 65 years). Response to chemotherapy with or without chest irradiation was almost comparable for the elderly and the non-elderly; complete response rate was 52% for limited disease (LD) and 33% for extensive disease (ED) in the elderly, and it was 68% for LD and 23% for ED in the non-elderly. Survival figures of the two groups were quite similar: The median survival time was 12.6 months for the elderly and 14.5 months for the non-elderly, and the 3-year survival rate was 14% for both groups. An improvement of patient survival was observed along with the chronology of the protocols, i.e., with a escalation of dose intensity. Of interest, the improvement was rather evident in the elderly than in the non-elderly. Hematologic toxicity was considerable more frequent and severe in the elderly than in the non-elderly with non-significant statistics. The incidense of fever episodes while neutropenic was significantly more frequent in the elderly. Non-hematologic toxicity was almost comparable for the two groups, with a exception that the elderly showed a trend being predisposed to renal toxicity. In conclusion, such elderly patients as eligible for entry into a protocol study can benefit from intensive treatment as equally as non-elderly patients can.

Tuberculosis in the elderly

Recently, the proportion of the elderly in the newly registered TB patients has increased. Not only the relative increase, but the newly registered TB patients older than 70 years is leveling off, and the number of smear positive TB patients among the elderly is obviously on the increase. The rapid aging of the population and the blunting of the decreasing speed of the TB patients percentage in the elderly may be accountable for the increase in the elderly TB patients. Elderly TB patients often have complications. Particularly noticeable is the high percentage of complications by cardiovascular diseases, malignant tumor, central nervous diseases and digestive tract diseases. However, the proportion of complications by diabetes was higher in the non-elderly persons (younger than 64 years). The frequency of pyrazinamide being used was extremely low in the elderly, particularly in the late cases of the elderly. In elderly TB patients, there were many cases of death and moving out, and the clinical results were poor. Of the female elderly TB patients, many were the late cases of the elderly and cases of moving out after discharge. Of the male elderly TB patients, there were many cases of death, which was conspicuous particularly in the late cases of the elderly. As the measures to counter the elderly TB patients who continue to increase in number, mention can be made of the early discovery of elderly TB patient, measures to prevent the development of TB in the elderly and support to hospital treatment of elderly TB patients. In the future, taking measures is needed so that the development of TB in the elderly be suppressed and that TB treatment of the elderly be carried out smoothly.     

Long-term prognosis after reperfusion therapy for acute myocardial infarction in elderly patients

Although it has been well demonstrated that TIMI grade 3 flow is associated with improved survival after acute myocardial infarction in non-elderly patients, its implication in elderly patients has not been clarified. To assess this issue, 1,115 patients with acute myocardial infarction who underwent coronary angiography within 24 hours after the onset of chest pain were studied: there were 131 elderly patients (age > or = 75 years) and 984 non-elderly patients (age < 75 years). Follow-up was achieved for 1,092 patients (98%). Elderly patients were associated with more female, Killip class > or = 2, 3 vessel disease and non-smokers. Although modality of reperfusion therapy was not different, final TIMI flow grade was less frequently obtained in elderly patients (53% vs 65%, p = 0.005). Elderly patients were associated with higher in-hospital mortality (25% vs 9%, p < 0.001) and lower 10 years cardiac death free rate (p < 0.001). Cox proportional hazards model showed that final TIMI flow grade 3 was an independent predictor of 10 years cardiac death free in elderly patients (odds ratio (OR) = 0.39, 95% confidence interval (CI) = 0.20-0.74, p = 0.004) as well as non-elderly patients (OR = 0.41, 95% CI = 0.29-0.58, p < 0.001). In conclusion, our data suggest that final TIMI grade 3 flow is an important determinant to improve short- and long-term survival after acute myocardial infarction in elderly patients as well as in non-elderly patients.

Elderly patients (≥ 80 years) with acute calculous cholangitis have similar outcomes as non-elderly patients (< 80 years): Propensity score-matched analysis

BACKGROUNDAcute cholangitis (AC) is a disease spectrum with varying extent of severity. Age ≥ 75 years forms part of the criteria for moderate (Grade II) severity in both the Tokyo Guidelines (TG13 and TG18). Aging is associated with reduced physiological reserves, frailty, and sarcopenia. However, there is evidence that age itself is not the determinant of inferior outcomes in elective and emergency biliary diseases. There is a paucity of reports comparing clinical outcomes amongst elderly patients vs non-elderly patients with AC.AIMTo investigate the effect of age (≥ 80 years) on AC''s morbidity and mortality using propensity score matching (PSM).METHODSThis is a single-center retrospective cohort study of all patients diagnosed with calculous AC (January 2016 to December 2016) and ≥ 80 years old (January 2012 to December 2016) at a tertiary university-affiliated teaching hospital. Inclusion criteria were patients who were treated for suspected or confirmed AC secondary to biliary stones. Patients with AC on a background of hepatobiliary malignancy, indwelling permanent metallic biliary stents, or concomitant pancreatitis were excluded. Elderly patients were defined as ≥ 80 years old in our study. A 1:1 PSM analysis was performed to reduce selection bias and address confounding factors. Study variables include comorbidities, vital parameters, laboratory and radiological investigations, and type of biliary decompression, including the time for endoscopic retrograde cholangiopancreatography (ERCP). Primary outcomes include in-hospital mortality, 30-d and 90-d mortality. Length of hospital stay (LOS) was the secondary outcome.RESULTSFour hundred fifty-seven patients with AC were included in this study (318 elderly, 139 non-elderly). PSM analysis resulted in a total of 224 patients (112 elderly, 112 non-elderly). The adoption of ERCP between elderly and non-elderly was similar in both the unmatched (elderly 64.8%, non-elderly 61.9%, P = 0.551) and matched cohorts (elderly 68.8% and non-elderly 58%, P = 0.096). The overall in-hospital mortality, 30-d mortality and 90-d mortality was 4.6%, 7.4% and 8.5% respectively, with no statistically significant differences between the elderly and non-elderly in both the unmatched and matched cohorts. LOS was longer in the unmatched cohort [elderly 8 d, interquartile range (IQR) 6-13, vs non-elderly 8 d, IQR 5-11, P = 0.040], but was comparable in the matched cohort (elderly 7.5 d, IQR 5-11, vs non-elderly 8 d, IQR 5-11, P = 0.982). Subgroup analysis of patients who underwent ERCP demonstrated the majority of the patients (n = 159/292, 54.5%) had delayed ERCP (> 72 h from presentation). There was no significant difference in LOS, 30-d mortality, 90-d mortality, and in-hospital mortality in patients who had delayed ERCP in both the unmatched and matched cohort (matched cohort: in-hospital mortality [n = 1/42 (2.4%) vs 1/26 (3.8%), P = 0.728], 30-d mortality [n = 2/42 (4.8%) vs 2/26 (7.7%), P = 0.618], 90-d mortality [n = 2/42 (4.8%) vs 2/26 (7.7%), P = 0.618], and LOS (median 8.5 d, IQR 6-11.3, vs 8.5 d, IQR 6-15.3, P = 0.929).CONCLUSIONMortality is indifferent in the elderly (≥ 80 years old) and non-elderly patients (< 80 years old) with AC.
