Objective We have analyzed short- and long-term variations of pulmonary function in locally advanced non–small cell lung cancer after induction chemoradiotherapy. Methods Twenty-seven patients with ...stage IIIA (N2) non–small cell lung cancer underwent resection with radical intent after induction chemoradiotherapy in the period 2003 to 2006. Pulmonary function has been evaluated by spirometry, diffusing capacity of the lung for carbon monoxide, and blood gas analysis before induction chemoradiotherapy (T0), 4 weeks after induction chemoradiotherapy and before surgery (T1), and 1 (T2), 3 (T3), 6 (T4), and 12 months (T5) after surgery. Results A 22.80% decrease of diffusing capacity of the lung for carbon monoxide ( P < .001) was observed at T1. At T2 significant decreases in the following were present: vital capacity, −20.50% ( P < .001); forced vital capacity, −22.50% ( P < .001); forced expiratory volume in 1 second, −23.00% ( P < .001); peak expiratory flow, −29.0 ( P < .001); forced expiratory flow 25% to 75%, −13.7% ( P = .005); and diffusing capacity of the lung for carbon monoxide, 43.6% ( P < .001). However, in the interval between T2 and T5, a progressive improvement of lung function in most parameters was observed, but only diffusing capacity of the lung for carbon monoxide presented a significant increase ( P < .001). Within the same time gap (T2 to T5), subjects 65 years of age or younger showed an increasing trend for vital capacity, forced expiratory volume in 1 second, total lung capacity, and residual volume significantly different from that of elderly patients, in whom a decrease in these parameters is reported. Conclusions An impairment of respiratory function is evident in the immediate postoperative setting in patients with non–small cell lung cancer receiving induction chemoradiotherapy. In the long-term period, a general recovery in diffusing capacity of the lung for carbon monoxide was found, whereas an improvement of forced expiratory volume in 1 second, vital capacity, total lung capacity, and residual volume was detected in the younger population only.
Background The use of small-bore wire-guided chest drains for pleural effusions and pneumothorax has become popular; however, limited data are available on its efficacy and morbidity. The aim of this ...retrospective study is to measure, via the analysis of the so far largest reported cohort, the efficacy, safety, and tolerability of this approach in different clinical conditions. Methods In the period from January 2002 to December 2008, 1092 patients have undergone the positioning of a small-bore wire-guided chest drain (12F) for the evidence of pneumothorax or pleural effusion and have been monitored over time for morbidity, pain at the time of insertion (measured via the visual analogue scale), and drain failure for misplacement or blockage. Patients with trauma were excluded from this study. Results Male/female ratio and mean age were respectively 418:674 and 55.85 ± 18.6. Three-hundred ninety-nine (36.5%) drains were inserted for pneumothorax, 324 (29.7%) for malignant effusion, 97 (8.9%) for empyema, and 272 (24.9%) for nonmalignant effusion. The pain experience was on average “very mild” (mean visual analogue scale = 4.6 mm). The overall drain failure rate was 12.9%. The percentage of successful cases was 93.8% in malignant effusion, 93% in pneumothorax, and 92.3% in nonmalignant effusion; in the cases of pathologically diagnosed empyema, drains were more likely to get blocked (74.2%). We recorded 1 serious complication within the malignant effusion group. Conclusions Wire-guided 12F Seldinger-type drains are a well-tolerated and effective method of treating pneumothorax and uncomplicated pleural effusions (malignant and nonmalignant) with acceptable morbidity. The use of 12F small-bore chest drain is not indicated for the treatment of empyema.
Background The impact of myasthenia gravis on patients with thymoma is still controversial when perioperative and long-term outcomes are analyzed. With the unique opportunity of a 35-year follow-up ...in a single institution, thymomatous myasthenia gravis cohort, we investigated the influence of early and long-term clinical predictors. Methods We reviewed a surgical series of 317 (1972 to 2007) patients with thymoma: clinical and pathologic features were analyzed as prognostic factors matched against the short- and long-term survival and recurrence rates. Results Male to female ratio was 153:164; median age, 49 years. Myasthenia gravis coexisted in 276 patients (87.1%). Thymomas were classified according to the Masaoka (42.0% stage I, 32.2% stage II, 21.5% stage III, and 4.4% stage IV) and the World Health Organization (3.5% type A, 9.5% type AB, 19.2% type B1, 57.7% type B2, 8.2% type B3, and 1.9% thymic carcinoma) staging systems. The resection was complete in 295 patients (93.1%). Operative mortality and morbidity were respectively 1.6% and 7.6%. No differences were recorded in postoperative outcome stratifying for myasthenia gravis or comorbidities. Mean follow-up was 144.7 ± 104.4 months. The overall 5-, 10-, 20-, and 30-year survival rates were 89.9%, 84.1%, 73%, and 58.6%, respectively. The completeness of resection ( p < 0.001), the Masaoka staging ( p = 0.010), and the World Health Organization classification ( p < 0.001) all significantly influenced the long-term survival (univariate analysis). Only completeness of resection was significantly correlated with a better prognosis ( p < 0.001) in multivariate analysis. Masaoka staging ( p < 0.001) and World Health Organization classification ( p < 0.001) significantly correlated with the disease-free survival in the univariate and multivariate analyses as significant prognostic factors (Masaoka, p < 0.001; World Health Organization, p = 0.011). Myasthenia gravis patients showed a better prognosis in terms of long-term survival ( p = 0.046) and disease-free survival ( p = 0.012) in the univariate analysis. Conclusions We confirm the evidence that the clinical staging and the histologic classification influence long-term survival. The presence of myasthenia gravis was not significantly related to operative outcome, but prolongs both long-term survival and disease-free survival.
In older adults co-occurrence of multiple diseases often leads to use of multiple medications (polypharmacy). The aim of the present study is to describe how prescription of medications varies across ...age groups, with specific focus on the oldest old.
We performed a cross-sectional study using 2013 data from the OsMed Health-DB database (mean number of medicines and defined daily doses prescribed in 15,931,642 individuals). There were 3,378,725 individuals age 65 years or older (21.2% of the study sample).
The mean number of prescribed medications progressively rose from 1.9 in the age group <65 years to 7.4 in the age group 80-84 years and then declined, with a more marked reduction in the age group 95 years or older with a mean number of 2.8 medications. A similar pattern was observed for the mean number of defined daily doses. Among participants age ≥65 years, proton pump inhibitors were the most commonly prescribed medication (40.9% of individuals ≥65 years), followed by platelet aggregation inhibitors (32.8%) and hydroxy-methylglutaryl-coenzyme A reductase inhibitors (26.1%). A decline in prescription was observed among individuals age 90 years or older, but this reduction was less consistent for medications used to treat acute conditions (ie, antibiotics and glucocorticoids) rather than preventive medicines commonly used to treat chronic diseases (ie, antihypertensive medications and hydroxy-methylglutaryl-coenzyme A reductase inhibitors).
The burden of medication treatment progressively increases till age 85 and substantially declines after age of 90 years. Patterns of medication prescription widely vary across age groups.
Abstract Objectives To explore temporal trends, geographic distribution, and socioeconomic determinants of scientific production in the field of cerebrovascular and cardiovascular disease (CCD) ...rehabilitation. Data Sources Citations from 1967 to 2008 were downloaded from the PubMed database. Core of the search strategy was the key word cardiovascular diseases in the Medical Subject Headings major field with the subheading rehabilitation. Journal Citation Reports was used to assign an impact factor (IF). Demographic and economic data were retrieved from the International Monetary Fund. Study Selection All articles retrieved were included in the bibliometric analysis. Data Extraction The search strategy was validated on a random sample of the articles retrieved. The search quality reflected the level of error of the PubMed database. Data Synthesis Publications retrieved were 10,379 and have grown 8.6 times in 40 years, faster than the all-diseases rehabilitation field (7.8 times), with a particularly steep growth for cerebrovascular diseases in the last 15 years (5 times). However, in the last decade, the articles’ quality (IF) decreased. From 1994 to 2008, 3466 citations were retrieved; 44.4% came from the European Union and 30.3% from the United States. The highest mean IF was reported for France (4.127). The United Kingdom and some relatively small northern European Union countries had the best ratio of IF (sum) to resident population or to gross domestic product. The most frequently used key word was stroke , and 3 journals ( Archives of Physical Medicine and Rehabilitation, Clinical Rehabilitation, and Stroke ) published one quarter of the articles. Conclusions The overall scientific production in the field of CCD rehabilitation showed a steep growth in the last decade, especially because of cerebrovascular research. In the same period, a decrease in the overall IF was observed. The European Union and the United States contributed 3 of every 4 articles in the field, although some Asian countries showed promising performance.
To assess the association of the anticholinergic medication burden with hospitalization and mortality in nursing home elderly patients and to investigate the role of coronary artery disease (CAD).
...Longitudinal (5-year) retrospective observational study.
Nursing homes in Italy.
A total of 3761 nursing home older residents.
A comprehensive clinical and functional assessment was carried out through the interRAI long-term care facility instrument. The anticholinergic burden was assessed through the anticholinergic cognitive burden (ACB) scale. Occurrence of hospitalization/all-cause mortality was the primary composite outcome. First hospitalization and all-cause mortality were the secondary outcomes of the study. Hazard ratios (HRs) and subdistribution HRs were obtained through Cox and competing risk (death as competing event for hospitalization) models.
Within the sample (mean age 83 ± 7 years; 72% females) the incidence rate of the primary outcome was 10/100 person-year. After adjusting for potential confounders and compared with participants with an ACB of 0, those with an ACB of 1 HR 1.46; 95% confidence interval (CI) 1.12-1.90 and ABC of 2+ (HR 1.41; 95% CI 1.11-1.79) presented an increased risk of developing the primary outcome. After stratification, the risk for the primary outcome increased along with the anticholinergic burden, only for participants affected by CAD (HR 1.53; 95% CI 0.94-2.50 and HR 1.71; 95% CI 1.09-2.68 for the ACB of 1 and ACB of 2+ groups). An ACB score of 2+ was marginally associated with first hospitalization, considering death as a competing risk, only for those with CAD (subdistribution HR 3.47; 95% CI 0.99-12.3).
Anticholinergic medication burden is associated to hospitalization and all-cause mortality in institutionalized older adults. CAD increases such risk. The effectiveness and safety profile of complex drug regimens should be reconsidered in this population.
