A prospective study evaluating the relationship between fatigue and patient satisfaction in advanced cancer

16025

Background: Fatigue is the most common and disabling symptoms experienced by cancer patients. No study has prospectively quantified the relationship between fatigue and patient satisfaction (PS) in advanced cancer. We therefore assessed this relationship before the start of chemotherapy and at 3 and 6 months after treatment at our integrative cancer treatment center. Methods: 294 cancer patients treated at Cancer Treatment Centers of America between 04/01 and 11/04. Of 954 patients at baseline, only 294 were available for follow-up at 6 months. Fatigue was measured using the EORTC QLQ-C30 3-item fatigue subscale. Scores ranged from 0–100, higher scores indicating more fatigue. PS was measured using Ferrans & Powers Quality of Life Index (QLI). Scores ranged from 0–30, higher scores indicating better QoL. The mean fatigue scores were compared using ANOVA across the 3 time periods at baseline, 3 and 6 months. The relationship between fatigue and QLI was evaluated using multiple linear regression at all 3 time points. Results: Of 294 patients, 106 were males and 188 females. 91 had breast ca, 52 colorectal, 43 lung, 25 pancreas, 13 prostate, and 70 had other cancers. 112 were newly diagnosed and 182 had received prior treatment elsewhere. The mean fatigue scores at baseline, 3 and 6 months were 43.6, 37.3, and 41.8 respectively; the scores at baseline and 3 months were significantly different (p = .009). At baseline, after controlling for age, gender, prior treatment history, and tumor stage at diagnosis, every 10 unit increase in fatigue was significantly associated with 1.3 units decrease in QLI health subscale. Similarly at 3 and 6 months after treatment, every 10 unit increase in fatigue was significantly associated with 1.2 and 1.4 units decrease in QLI health subscale. Conclusions: In our study, we found that fatigue is a strong correlate of PS independent of the effects of age, gender, prior treatment history and tumor stage at diagnosis during the first 6 months of treatment. Interestingly, fatigue showed a significant improvement after 3 months of treatment and returned back to baseline levels at 6 months. This finding needs to be investigated further to evaluate the impact of integrative cancer care services on PS.

Mucosal tear in the oropharynx leading to pneumopericardium and pneumomediastinum: An unusual complication of blunt trauma to the face and neck

Pneumomediastinum and pneumopericardium are very rare complications resulting from blunt trauma to the head and neck. We report the case of a 40-year-old male who had been assaulted. He presented to the Emergency Department with bruises to the face and neck and complained of dysphagia. He was found to have extensive subcutaneous emphysema of the face and neck. Imaging revealed the presence of a mucosal tear in the oropharynx leading to pneumomediastinum and pneumopericardium. He was managed conservatively and made an uneventful recovery. This is a very rare but potentially life-threatening complication of blunt trauma to the head and neck. It poses diagnostic difficulties and treatment dilemmas, which are discussed.

Ketamine for treatment of catheter related bladder discomfort: a prospective, randomized, placebo controlled and double blind study

BACKGROUND

Intraoperative urinary catheterization might cause postoperative catheter related bladder discomfort (CRBD). We evaluated the efficacy of ketamine as a treatment modality for CRBD.

METHODS

Fifty-four, ASA physical status I and II, male and female adult patients, having CRBD after elective percutaneous nephrolithotomy were randomized into two equal groups of 27 each. In the postoperative period, patients who complained of CRBD received medication depending upon group allocation. Group 1 (Control) received placebo, Group II (Ketamine) received i.v. ketamine 250 microg kg(-1). After induction of anaesthesia patients were catheterized with a 16 Fr Foley's catheter and the balloon was inflated with 10 ml distilled water. Grading of CRBD was done as none, mild, moderate and severe by a blinded observer at 0, 1, 2 and 6 h after operation.

RESULTS

Ketamine reduced the incidence of CRBD (P<0.001) at 2 and 6 h along with reduction in severity (P<0.05) at 1 h compared with control. Higher incidence of mild sedation was observed in the ketamine group (P<0.05) which was not associated with any untoward effects. Operative time and intraoperative fentanyl requirement were similar in both the groups.

CONCLUSION

I.V. ketamine (250 microg kg(-1)) is an effective treatment for reducing the incidence and severity of postoperative CRBD.

Failure of NIV in acute asthma: case report and a word of caution

Noninvasive ventilation (NIV) is the provision of ventilatory support without the need for an invasive airway, and has revolutionized the management of patients with diverse forms of respiratory failure. The advantages of NIV include improved patient comfort and reduced need for sedation, while avoiding the complications of endotracheal intubation, including upper airway trauma, sinusitis, otitis, and nosocomial pneumonia. In selected patients, NIV has also been shown to improve survival. The role of NIV in acute severe asthma is at best controversial. In this case report, we describe a patient with acute severe asthma who was initially managed and failed with NIV, and was successfully managed with invasive ventilation. We also review the pathophysiological mechanisms of benefit of NIV in acute severe asthma, and the current literature on the use of NIV in acute asthma. In conclusion, a trial of NIV in acute asthma may be justified in carefully selected and monitored patients who do not respond to initial medical therapy. However, as its role is not clear and as the condition of an asthmatic patient may deteriorate abruptly, extreme caution is advisable to recognize failure of NIV as in the case presented here. Facilities for immediate endotracheal intubation and next level of treatment should be readily available.

Non-invasive ventilation in acute cardiogenic pulmonary oedema

Non-invasive ventilation (NIV) is the delivery of assisted mechanical ventilation to the lungs, without the use of an invasive endotracheal airway. NIV has revolutionised the management of patients with various forms of respiratory failure. It has decreased the need for invasive mechanical ventilation and its attendant complications. Cardiogenic pulmonary oedema (CPO) is a common medical emergency, and NIV has been shown to improve both physiological and clinical outcomes. From the data presented herein, it is clear that there is sufficiently high level evidence to favour the use of continuous positive airway pressure (CPAP), and that the use of CPAP in patients with CPO decreases intubation rate and improves survival (number needed to treat seven and eight respectively). However, there is insufficient evidence to recommend the use of bilevel positive airway pressure (BiPAP), probably the exception being patients with hypercapnic CPO. More trials are required to conclusively define the role of BiPAP in CPO.

Flexible naso-endoscopic decontamination—rationalizing the next step forward

Naso-endoscopes are important tools in the everyday practice of otolaryngology. However, cleaning methods have not yet been standardized. The aims of this article are to assess the degree of variation in practice both within and outside the UK, and to propose explanations why standard national and international guidelines have not been forthcoming. It is hoped that the systematic identification of the problems facing health authorities will lead to a better understanding of the task at hand, and bring us closer to drawing up a more specific standard for 'best possible' practice.

Circadian function in patients with advanced non-small-cell lung cancer

This study aimed to evaluate whether patients with advanced non-small-cell lung cancer experience disrupted rest–activity daily rhythms, poor sleep quality, weakness, and maintain attributes that are linked to circadian function such as fatigue. This report describes the rest–activity patterns of 33 non-small-cell lung cancer patients who participated in a randomised clinical trial evaluating the benefits of melatonin. Data are reported on circadian function, health-related quality of life (QoL), subjective sleep quality, and anxiety/depression levels prior to randomisation and treatment. Actigraphy data, an objective measure of circadian function, demonstrated that patients' rest–activity circadian function differs significantly from control subjects. Our patients reported poor sleep quality and high levels of fatigue. Ferrans and Powers QoL Index instrument found a high level of dissatisfaction with health-related QoL. Data from the European Organization for Research and Treatment for Cancer reported poor capacity to fulfil the activities of daily living. Patients studied in the hospital during or near chemotherapy had significantly more abnormal circadian function than those studied in the ambulatory setting. Our data indicate that measurement of circadian sleep/activity dynamics should be accomplished in the outpatient/home setting for a minimum of 4–7 circadian cycles to assure that they are most representative of the patients' true condition. We conclude that the daily sleep/activity patterns of patients with advanced lung cancer are disturbed. These are accompanied by marked disruption of QoL and function. These data argue for investigating how much of this poor functioning and QoL are actually caused by this circadian disruption, and, whether behavioural, light-based, and or pharmacologic strategies to correct the circadian/sleep activity patterns can improve function and QoL.

Evaluation of self-care manual in bronchial asthma

BACKGROUND

Asthma continues to be a substantial cause of morbidity. Various educational programmes have shown an increase in knowledge and self-management skills of asthmatic patients and also revealed a reduction of severe attacks, hospitalisations and days lost from work.

METHODS

A self-care manual on bronchial asthma was prepared. A total of 523 bronchial asthma patients were enrolled in the study. Out of these, 260 patients were included in the study group to whom self-care manual was provided and 263 were included in the control group to whom no specific instructions were given. After the initial interview (0 week), follow up of all the patients was carried out at two weeks, six months and at one year.

RESULTS

Out of the enrolled patients, 240 (92.31%) and 240 (91.25%), 212 (81.54%) and 210 (79.85%), and 204 (78.46%) and 194 (73.76%) patients completed the follow up at two weeks, six months and one year in the two groups, respectively. Various parameters analysed were knowledge of the patients, their symptomatology, various triggering factors which were inducing and/or precipitating symptoms, the self-care measures they adopted at the time of acute attacks and the indices of asthma morbidity during the last one year. The knowledge scores were significantly higher at all the three follow up visits (F = 633. 98, p < 0.001) as compared to the baseline in the study group patients. In both the groups, the symptom scores decreased at all the follow up visits (F = 71.78, p < 0.001 in the study group and F = 24.19, p < 0.001 in the control group). Multiple logistic regression analysis showed a significant improvement in knowledge and symptoms in the study group as compared to controls after adjusting for various confounding variables (p < 0.001). The number of patients whose symptoms were induced and/or precipitated by exposure to various triggering factors was significantly reduced in study group for all the triggers. There was a statistically significant decrease in the number of severe attacks, number of emergency visits and need of injections during last one year in both the groups, though the differences were more marked in the study group. However, there was a significant decrease in hospital admissions and absence from school/or job in the study group at one year as compared to the control group.

CONCLUSION

The self-care manual was effective in self-management of bronchial asthma.

A multicentric study on epidemiology of chronic obstructive pulmonary disease and its relationship with tobacco smoking and environmental tobacco smoke exposure

INTRODUCTION

Population prevalence of chronic obstructive pulmonary disease (COPD) and its relationship with tobacco smoking, environmental tobacco smoke (ETS) exposure and other variables were studied in adult subjects of 35 years and above at four different centres in India. Question-items for the diagnosis of COPD were included in the questionnaire used for the field study on asthma epidemiology.

METHODS

Field surveys were conducted in both the urban and the rural populations at Bangalore, Chandigarh, Delhi and Kanpur with the help of a structured and validated questionnaire for diagnosis of asthma and COPD. Separate sets of questions were used for the diagnoses of the two diseases. A two-stage stratified sample design was employed where a village or an urban locality formed the first stage unit and a household formed the second stage unit. A uniform methodology was used at all the four centres and the analyses were done at the central coordinating centre--Chandigarh. Chronic obstructive pulmonary disease, defined by chronic bronchitis (CB) criteria, was diagnosed from the presence of cough and expectoration on most of the days for at least three months in a year for two consecutive years or more.

RESULTS

Chronic obstructive pulmonary disease was diagnosed in 4.1% of 35295 subjects, with a male to female ratio of 1.56:1 and a smoker to nonsmoker ratio of 2.65: 1. Prevalence among bidi and cigarette smokers was 8.2% and 5.9%, respectively. Odds ratio (OR) for COPD was higher for men, elderly individuals, lower socio-economic status and urban (or mixed) residence. Environmental tobacco smoke exposure among nonsmokers had an OR of 1.4(95% CI 1.21-1.61). Combined exposure to both ETS and solid fuel combustion had higher OR than for ETS exposure alone.

CONCLUSIONS

Population prevalence of COPD is very high in India with some centre to centre differences. Smoking of both bidis and cigarettes, and ETS exposure among nonsmokers, were two important risk factors at all centres. It is important to employ uniform methodology for assessment of national burden and disease-surveillance programme.

Tobacco smoking in India: prevalence, quit-rates and respiratory morbidity

BACKGROUND

Population prevalence of tobacco smoking especially with reference to detailed habits such as the amount smoked, the smoking forms, quit-rates and relationship with demographic variables were studied at four different centres in India along with the study on epidemiology of asthma and chronic obstructive pulmonary disease.

METHODS

The study population included adults of over 15 years of age selected with two-stage stratified random sample design. A specifically designed questionnaire was used for the study.

RESULTS

There were 11496 (15.6%) ever smokers in the study sample of 73605 subjects. Among 37682 males, 10756 (28.5%) were ever smokers and among 35923 females, 740 (2.1%) were ever smokers. Bidi was the commonest form of smoking, more so in the rural areas. The mean number of cigarettes/bidis smoked per day was 14 (+/- 11.5) and the mean age of starting smoking was 20.5 (+/- 20.0) years. Increasing age, low socio-economic status and rural residence were important factors associated with smoking. Vigorous anti-tobacco measures under the tobacco control programmes yielded only a quit-rate of 10 percent. Nearly 14% of ever smokers had some respiratory symptoms.

CONCLUSIONS

A substantial proportion of population in India has current or past smoking habit with higher prevalence among males than females. The quit-rates have been low in spite of the various anti-tobacco measures. There is a significant respiratory morbidity associated with smoking.

Prevalence and risk factors for bronchial asthma in Indian adults: a multicentre study

BACKGROUND

There is limited information on field epidemiology of bronchial asthma in Indian adults.

OBJECTIVES

To estimate prevalence of bronchial asthma in different regions of India and to define risk factors influencing disease prevalence.

METHODS

A field study was conducted at Chandigarh, Delhi, Kanpur and Bangalore through a two stage stratified (urban/ rural) sampling and uniform methodology using a previously validated questionnaire. Asthma was diagnosed if the respondent answered affirmatively both to (a) whistling sound from chest, or chest tightness, or breathlessness in morning, and (b) having suffered from asthma, or having an attack of asthma in the past 12 months, or using bronchodilators. Besides demographic data, information on smoking habits, domestic cooking fuel used, atopic symptoms, and family history suggestive of asthma was also collected. Univariate and multivariate logistic regression modelling was performed to calculate odds ratio of various potential risk factors.

RESULTS

Data from 73605 respondents (37682 men, 35923 women) were analysed. One or more respiratory symptoms were present in 4.3-10.5% subjects. Asthma was diagnosed in 2.28%, 1.69%, 2.05 and 3.47% respondents respectively at Chandigarh, Delhi, Kanpur and Bangalore, with overall prevalence of 2.38%. Female sex, advancing age, usual residence in urban area, lower socio-economic status, history suggestive of atopy, history of asthma in a first degree relative, and all forms of tobacco smoking were associated with significantly higher odds of having asthma.

CONCLUSION

Prevalence estimates of asthma in adults in this study, although lower than several previously reported figures, point to a high overall national burden of disease.

Household environmental tobacco smoke exposure, respiratory symptoms and asthma in non-smoker adults: a multicentric population study from India

BACKGROUND

Exposure to environmental tobacco smoke (ETS) is a risk factor for childhood asthma. Its association with asthma in adults is less clear.

METHODS

In a multicentric population study on asthma prevalence in adults, specific enquiries were made into childhood and adulthood exposure to household ETS, and its relationship with asthma diagnosis were analysed.

RESULTS

From a total of 73605 respondents, 62109 were studied after excluding current or past smokers. Overall observed prevalence of asthma was 2.0% (men 1.5%,women 2.5%, p < 0.001). Of all asthma patients, history of ETS exposure was available in 48.6 percent. Prevalence of asthma in the ETS exposed subjects was higher compared to non-exposed individuals (2.2% vs 1.9%, p < 0.05). Multiple logistic regression analysis showed a higher risk of having asthma in persons who were exposed to ETS compared to those not exposed (odds ratio [OR] 1.22, 95% CI 1.08-1.38) after adjusting for age, gender, usual residence, exposure to biomass fuels and atopy. Stratification of ETS exposure revealed that exposure during childhood and both during childhood and adulthood were significantly associated with asthma prevalence. Exposure only in adulthood was not a significant risk factor (OR 1.13, 95% CI 0.95-1.33). Persons reporting combined environmental tobacco smoke exposure from parents during childhood and spouse during adulthood had highest risk of having asthma (OR 1.69, 95% CI 1.38-2.07). Environmental tobacco smoke exposure was also significantly associated with prevalence of respiratory symptoms such as wheezing, cough and breathlessness.

CONCLUSIONS

Environmental tobacco smoke exposure during childhood is an important risk factor for asthma and respiratory symptoms in non-smoking adults.

Pulmonary mucormycosis: two of a kind

Mucormycosis is an uncommon infection caused by fungi of the class Zygomycetes, suborder Mucorales. It occurs predominantly in the immunodeficient host, the most common risk factor being diabetes mellitus. Pulmonary mucormycosis is a disease that is localized in the lungs or mediastinum. It usually presents in a fulminant manner, although a chronic presentation can also occur. We describe two cases of pulmonary mucormycosis in patients with diabetes mellitus, one with an acute and the other with a chronic presentation. A high level of clinical suspicion, combined surgical and medical therapy, and control of patient's underlying immunosuppression are the key to a successful outcome.

Opioid sparing during endotracheal intubation using McCoy laryngoscope in neurosurgical patients: the comparison of haemodynamic changes with Macintosh blade in a randomized trial

BACKGROUND

There is conflicting data in literature to show that the McCoy laryngoscope is less stressful and opioids can actually be avoided during laryngoscopy and intubation with the use of this laryngoscope.

AIM

A comparison of hemodynamic changes with McCoy vs Macintosh laryngoscope..

SETTINGS AND DESIGN

180 ASA I and II neurosurgical patients undergoing elective surgery for space occupying lesions were recruited. The study was was prospective, randomized and blinded in the setting of neurosurgical perioperative services.

METHODS AND MATERIALS

The patients were divided into four groups (Gr.1 McCoy and fentanyl; Gr. 2 McCoy and no fentanyl; Gr. 3 Macintosh and fentanyl; Gr. 4 Macintosh and no fentanyl). In Gr. 2 and 4 equivalent volume of saline was given in place of fentanyl as placebo. Heart rate, systolic and diastolic blood pressure were measured after laryngoscopy, after intubation and subsequently every minute for the next five minutes. The incidence of cough due to fentanyl treatment was observed.

STATISTICAL ANALYSIS

Haemodynamic changes were compared between and within groups using oneway ANOVA and repeated measures ANOVA. All analysis included 95% CI at 5% significance. The Mann Whitney U test was used for comparing incidence of cough.

RESULTS

No difference was found between McCoy laryngoscopy when done with or without fentanyl pretreatment (HR p=0.848, sys BP p=0.229 and diastolic blood pressure p=0.981). Significant changes in haemodynamic parameters were seen between Macintosh and McCoy laryngoscopy without fentanyl pretreatment (p<0.001) whereas changes were blunted with fentanyl pretreatment in Macintosh laryngoscopy (p<0.05).

CONCLUSIONS

McCoy laryngoscope blade is less stressful and fentanyl pretreatment is not necessary to attenuate haemodynamic responses with its use in ASA I and II patients.
