The effectiveness of treatment for depression/depressive symptoms in adults with cancer: a systematic review.

Depression is common in cancer patients, and this often remains undetected and untreated. Depression has been associated with poorer quality of life, in addition to increased impairment of immune response and poorer survival in cancer patients. Previous systematic reviews and meta-analyses of the efficacy of interventions for cancer patients with depression have failed to distinguish between caseness for depression and depressive symptoms. The findings from this systematic review show that there is limited trial data on the efficacy of prescribed antidepressants in reducing the incidence of major depression and depressive symptoms in cancer patients. Contrary to previous reviews that failed to distinguish between depressive symptoms and depression, this review found very little data from clinical trials (without the possibility of confounding factors) to demonstrate that psychotherapeutic interventions are effective in reducing depression in cancer patients. A number of small-scale, single-centre trials indicated that psychotherapeutic interventions (especially cognitive behavioural therapy) can have effects on depressive symptoms in cancer patients. However, given the methodological limitations of studies to date, lack of evidence should not be interpreted as implying lack of efficacy. In conclusion, there is a need for adequately powered studies of pharmacological and psychotherapeutic studies, which are targeted at cancer patients with a diagnosis of depression and include monitoring of the use of other pharmacological/psychotherapeutic and complementary and alternative medicine interventions.

Advances in molecular classification of renal neoplasms.

Kidney neoplasms are classified by light microscopy using the World Health Organization (WHO) system. The WHO system defines histopathologic tumor subtypes with distinct clinical behavior and underlying genetic mutations. In adults, the common malignant subtypes are variants of renal cell carcinoma (RCC). Histopathologic classification is critical for clinical management of RCC, but is becoming more complex with recognition of novel tumor subtypes, development of procedures yielding small diagnostic biopsies, and emergence of molecular therapies directed at tumor gene activity. Therefore, classification systems based on gene expression are likely to become essential for diagnosis, prognosis and treatment of kidney tumors. Recent DNA microarray studies have shown that clinically relevant renal tumor subtypes are characterized by distinct gene expression profiles, which are useful for discovery of novel diagnostic and prognostic biomarkers. In this review, we summarize the WHO classification system for renal tumors, general applications of microarray technology in cancer research, and specific microarray studies that have advanced knowledge of renal tumor diagnosis, prognosis, therapy and pathobiology.

Gaps between policy, protocols and practice: a qualitative study of the views and practice of emergency ambulance staff concerning the care of patients with non-urgent needs.

AIM: To describe emergency ambulance crews' views about (1) how they make decisions on whether to convey patients to hospital; (2) an intervention enabling them to triage patients to non-conveyance; and (3) their experience of using new protocols for undertaking such triage. METHODS: Two focus groups were held at the outset of an evaluation of Treat and Refer (T&R) protocols: one with staff based at an ambulance station who were to implement the new service (intervention station), and the other with staff from a neighbouring station who would be continuing their normal practice during the study (control station). A third session was held with staff from the intervention station following training and 3 months' experience of protocol usage. RESULTS: Before the introduction of the T&R protocols, crews reported experience, intuition, training, time of call during shift, patient preference, and home situation as influencing their decisions concerning conveyance. Crews were positive about changing practice but foresaw difficulties with advising patients who wanted to go to hospital, and with referral to other agencies. Following experience of T&R protocol use, crews felt they had needed more training than had been provided. Some felt their practice and job satisfaction had improved. Problems with referral and with persuading some patients that they did not need to go to hospital were discussed. There was consensus that the initiative should be introduced across the service. CONCLUSIONS: With crews generally positive about this intervention, an opportunity to tackle this difficult area of emergency care now exists. This study has, however, highlighted the complexity of the change in practice and service delivery, and professional and organisational constraints that need to be considered.

On-scene alternatives for emergency ambulance crews attending patients who do not need to travel to the accident and emergency department: a review of the literature.

With rising demand and recognition of the variety of cases attended by emergency ambulance crews, services have been considering alternative ways of providing non-urgent care. This paper describes and appraises the research literature concerning on-scene alternatives to conveyance to an emergency department, focusing on the: (1) profile and outcomes of patients attended but not conveyed by emergency crews; (2) triage ability of crews; (3) effectiveness and safety of protocols that allow crews to convey patients to alternative receiving units or to self care. The literature search was conducted through standard medical databases, supplemented with manual searches. Very few "live" studies were identified, and fewer still that included a control group. Findings indicated a complex area, with the introduction of protocols allowing crews to leave patients at scene carrying clinical risk. Robust research evidence concerning alternatives to current emergency care models is needed urgently to inform service and practice development.

Safety of telephone consultation for "non-serious" emergency ambulance service patients.

OBJECTIVE: To assess the safety of nurses and paramedics offering telephone assessment, triage, and advice as an alternative to immediate ambulance dispatch for emergency ambulance service callers classified by lay call takers as presenting with "non-serious" problems (category C calls). DESIGN: Data for this study were collected as part of a pragmatic randomised controlled trial reported elsewhere. The intervention arm of the trial comprised nurse or paramedic telephone consultation using a computerised decision support system to assess, triage, and advise patients whose calls to the emergency ambulance service had been classified as "non-serious" by call takers applying standard priority dispatch criteria. A multidisciplinary expert clinical panel reviewed data from ambulance service, accident and emergency department, hospital inpatient and general practice records, and call transcripts for patients triaged by nurses and paramedics into categories that indicated that dispatch of an emergency ambulance was unnecessary. All cases for which one or more members of the panel rated that an emergency ambulance should have been dispatched were re-reviewed by the entire panel for an assessment of the "life risk" that might have resulted. SETTING: Ambulance services in London and the West Midlands, UK. STUDY POPULATION: Of 635 category C patients assessed by nurses and paramedics, 330 (52%) cases that had been triaged as not requiring an emergency ambulance were identified. MAIN OUTCOME MEASURES: Assessment of safety of triage decisions. RESULTS: Sufficient data were available from the routine clinical records of 239 (72%) subjects to allow review by the specialist panel. For 231 (96.7%) sets of case notes reviewed, the majority of the panel concurred with the nurses' or paramedics' triage decision. Following secondary review of the records of the remaining eight patients, only two were rated by the majority as having required an emergency ambulance within 14 minutes. For neither of these did a majority of the panel consider that the patient would have been at "life risk" without an emergency ambulance being immediately dispatched. However, the transcripts of these two calls indicated that the correct triage decision had been communicated to the patient, which suggests that the triage decision had been incorrectly entered into the decision support system. CONCLUSIONS: Telephone advice may be a safe method of managing many category C callers to 999 ambulance services. A clinical trial of the full implementation of this intervention is needed, large enough to exclude the possibility of rare adverse events.

Towards primary care for non-serious 999 callers: results of a controlled study of "Treat and Refer" protocols for ambulance crews.

OBJECTIVE: To develop and evaluate "Treat and Refer" protocols for ambulance crews, allowing them to leave patients at the scene with onward referral or self-care advice as appropriate. METHODS: Crew members from one ambulance station were trained to use the treatment protocols. Processes and outcomes of care for patients attended by trained crews were compared with similar patients attended by crews from a neighbouring station. Pre-hospital records were collected for all patients. Records of any emergency department and primary care contacts during the 14 days following the call were collected for non-conveyed patients who were also followed up by postal questionnaire. RESULTS: Twenty three protocols were developed which were expected to cover over 75% of patients left at the scene by the attending crew. There were 251 patients in the intervention arm and 537 in the control arm. The two groups were similar in terms of age, sex and condition category but intervention cases were more likely to have been attended during daytime hours than at night. There was no difference in the proportion of patients left at the scene in the intervention and control arms; the median job cycle time was longer for intervention group patients. Protocols were reported as having been used in 101 patients (40.2%) in the intervention group; 17 of the protocols were recorded as having been used at least once during the study. Clinical documentation was generally higher in the intervention group, although a similar proportion of patients in both groups had no clinical assessments recorded. 288 patients were left at the scene (93 in the intervention group, 195 in the control group). After excluding those who refused to travel, there were three non-conveyed patients in each group who were admitted to hospital within 14 days of the call who were judged to have been left at home inappropriately. A higher proportion of patients in the intervention arm reported satisfaction with the service and advice provided. CONCLUSIONS: "Treat and Refer" protocols did not increase the number of patients left at home but were used by crews and were acceptable to patients. The protocols increased job cycle time and some safety issues were identified. Their introduction is complex, and the extent to which the content of the protocols, decision support and training can be refined needs further study.

Attitudes of GPs towards the provision of acupuncture on the NHS.

OBJECTIVE: To investigate the attitudes of General Practitioners (GPs) to acupuncture, whether they think it should be available on the NHS and, if so, how it should be provided. DESIGN: Attitudinal postal survey. SETTING: All 65 practising GPs in the 12 GP practices of the Melton Rutland & Harborough Primary Care Group, UK. RESULTS: A response rate of 83% was achieved. The main findings show that 59% of GPs agreed that acupuncture should be available on the NHS, 83% agreed that it can be clinically useful and 72% that it can be cost effective. Among GPs who acknowledged the potential for an increased role for acupuncture on the NHS there was support for the provision of treatment from either medical or non-medical practitioners, delivered at either NHS or non-NHS premises, and with the NHS providing some, or all, of the required funding. CONCLUSION: The findings suggest that a majority of GPs are in favour of acupuncture being more widely available on the NHS.

Computer assisted assessment and advice for "non-serious" 999 ambulance service callers: the potential impact on ambulance despatch.

OBJECTIVE: To investigate the potential impact for ambulance services of telephone assessment and triage for callers who present with non-serious problems (Category C calls) as classified by ambulance service call takers. DESIGN: Pragmatic controlled trial. Calls identified using priority dispatch protocols as non-serious were allocated to intervention and control groups according to time of call. Ambulance dispatch occurred according to existing procedures. During intervention sessions, nurses or paramedics within the control room used a computerised decision support system to provide telephone assessment, triage and, if appropriate, offer advice to permit estimation of the potential impact on ambulance dispatch. SETTING: Ambulance services in London and the West Midlands. SUBJECTS: Patients for whom emergency calls were made to the ambulance services between April 1998 and May 1999 during four hour sessions sampled across all days of the week between 0700 and 2300. MAIN OUTCOME MEASURES: Triage decision, ambulance cancellation, attendance at an emergency department. RESULTS: In total, there were 635 intervention calls and 611 controls. Of those in the intervention group, 330 (52.0%) were triaged as not requiring an emergency ambulance, and 119 (36.6%) of these did not attend an emergency department. This compares with 55 (18.1%) of those triaged by a nurse or paramedic as requiring an ambulance (odds ratio 2.62; 95% CI 1.78 to 3.85). Patients triaged as not requiring an emergency ambulance were less likely to be admitted to an inpatient bed (odds ratio 0.55; 95% CI 0.33 to 0.93), but even so 30 (9.2%) were admitted. Nurses were more likely than paramedics to triage calls into the groups classified as not requiring an ambulance. After controlling for age, case mix, time of day, day of week, season, and ambulance service, the results of a logistic regression analysis revealed that this difference was significant with an odds ratio for nurses:paramedics of 1.28 (95% CI 1.12 to 1.47). CONCLUSIONS: The findings indicate that telephone assessment of Category C calls identifies patients who are less likely to require emergency department care and that this could have a significant impact on emergency ambulance dispatch rates. Nurses were more likely than paramedics to assess calls as requiring an alternative response to emergency ambulance despatch, but the extent to which this relates to aspects of training and professional perspective is unclear. However, consideration should be given to the acceptability, reliability, and cost consequences of this intervention before it can be recommended for full evaluation.

A survey of current consultant practice of treatment of severe ankle sprains in emergency departments in the United Kingdom.

OBJECTIVE: To determine current consultant practice in larger UK emergency departments in the management of severe ankle sprains. DESIGN: Questionnaire study to all UK emergency departments seeing more than 50 000 new patients per year. RESULTS: 70% response rate. Most popular treatment was ice, elevation, Tubigrip, and exercise, each of which was reported as used in most cases by over 70% of respondents. Crutches, early weight bearing, and non-steroidal anti-inflammatory drugs were each reported as used in most cases at over half of responding departments. Physiotherapy was usually only used in selected cases. Rest was usually advised for one to three days (35%). Follow up was only recommended for selected patients. CONCLUSIONS: The results of this survey suggest that there is considerable variation in some aspects of the clinical approach (including drug treatment, walking aids, periods of rest) taken to the management of severe ankle sprains in the UK, although in some areas (for example, not routinely immobilising, early weight bearing as pain permits, use of physiotherapy, use of rest, ice, and elevation) there was concordance.

Weight gain following treatment of hyperthyroidism.

OBJECTIVE: Patients frequently express concern that treating hyperthyroidism will lead to excessive weight gain. This study aimed to determine the extent of, and risk factors for, weight gain in an unselected group of hyperthyroid patients. DESIGN AND SUBJECTS: We investigated 162 consecutive hyperthyroid patients followed for at least 6 months. Height, weight, clinical features, biochemistry and management were recorded at each clinic visit. RESULTS: Documented weight gain was 5.42 +/- 0.46 kg (mean +/- SE) and increase in BMI was 8.49 +/- 0.71%, over a mean 24.2 +/- 1.6 months. Pre-existing obesity, Graves' disease causing hyperthyroidism, weight loss before presentation and length of follow-up each independently predicted weight gain. Patients treated with thionamides or radioiodine gained a similar amount of weight (thionamides, n = 87, 5.16 +/- 0.63 kg vs. radioiodine, n = 62, 4.75 +/- 0.57 kg, P = 0.645), but patients who underwent thyroidectomy (n = 13) gained more weight (10.27 +/- 2.56 kg vs. others, P = 0.007). Development of hypothyroidism (even transiently) was associated with weight gain (never hypothyroid, n = 102, 4.57 +/- 0.52 kg, transiently hypothyroid, n = 29, 5.37 +/- 0.85 kg, on T4, n = 31, 8.06 +/- 1.42 kg, P = 0.014). This difference remained after correcting for length of follow-up. In the whole cohort, weight increased by 3.95 +/- 0.40 kg at 1 year (n = 144) to 9.91 +/- 1.62 kg after 4 years (n = 27) (P = 0.008), representing a mean weight gain of 3.66 +/- 0.44 kg/year. CONCLUSION: We have demonstrated marked weight gain after treatment of hyperthyroidism. Pre-existing obesity, a diagnosis of Graves' disease and prior weight loss independently predicted weight gain and weight continued to rise with time. Patients who became hypothyroid, despite T4 replacement, gained most weight.

What is chronic fatigue syndrome? Heterogeneity within an international multicentre study.

OBJECTIVE: We sought to compare the characteristics of patients presenting with chronic fatigue (CF) and related syndromes in eight international centres and to subclassify these subjects based on symptom profiles. The validity of the subclasses was then tested against clinical data. METHOD: Subjects with a clinical diagnosis of CF completed a 119-item self-report questionnaire to provide clinical symptom data and other information such as illness course and functional impairment. Subclasses were generated using a principal components-like analysis followed by latent profile analysis (LPA). RESULTS: 744 subjects returned complete data sets (mean age 40.8 years, mean length of illness 7.9 years, female to male ratio 3:1). Overall, the subjects had a high rate of reporting typical CF symptoms (fatigue, neuropsychological dysfunction, sleep disturbance). Using LPA, two subclasses were generated. Class one (68% sample) was characterized by: younger age, lower female to male ratio; shorter episode duration; less premorbid, current and familial psychiatric morbidity; and, less functional disability. Class two subjects (32%) had features more consistent with a somatoform illness. There was substantial variation in subclass prevalences between the study centres (Class two range 6-48%). CONCLUSIONS: Criteria-based approaches to the diagnosis of CF and related syndromes do not select a homogeneous patient group. While substratification of patients is essential for further aetiological and treatment research, the basis for allocating such subcategories remains controversial.

Patient-perceived benefits of and barriers to using out-of-hours primary care centres.

BACKGROUND: The rapid growth of GP co-operatives has encouraged the development of primary care centres, but little is known about patients' views and experiences of these new forms of out-of-hours service delivery. OBJECTIVES: This study was designed to understand patients' views, expectations and experiences of attending an out-of-hours primary care centre which was part of an inner London GP co-operative. METHODS: Systematic samples of patients using the out-of-hours service received semi-structured interviews covering the decision to contact the service, expectations and experience of the service and, if relevant, the experience of travelling to the primary care centre. Interviews were conducted by telephone between 7 and 10 days after patient contact. RESULTS: Interviews were completed with 55.4% (72/130) of sampled patients who were primary care centre attenders, 50.0% (47/94) of those receiving telephone advice and 45.3% (53/117) of those receiving a home visit. Most attenders of the primary care centre said that they were satisfied with the consultation (90.0%, 65) and were able to get all the help they needed (83%, 60). The speed of being seen and the opportunity of having a face-to-face consultation were key benefits identified. For some, this outweighed difficulties experienced in attending the centre, including arranging transport, caring for other children, managing several children on the journey and travelling while ill. The main barriers patients identified for not wanting to attend the primary care centre included feeling too ill to travel, having other dependants to care for or lacking transportation. CONCLUSIONS: While primary care centres offer patients speedy access to face-to-face consultations, there are a range of obstacles which are encountered. Those who are socially disadvantaged appear likely to experience greatest difficulty, raising concerns about equity in access to services. Out-of-hours services may need to give consideration to patient transport and a more flexible approach to visiting at home if such inequities are to be avoided.

Patients' experiences of receiving telephone advice from a GP co-operative.

BACKGROUND: The use of the telephone to deliver health care advice has increased considerably in recent years. Little research has been carried out to explore the experience of patients who receive such advice and its acceptability. OBJECTIVES: The aim of this study is to describe the expectations of patients, or third party callers, who had contacted a GP out-of-hours co-operative and their satisfaction with telephone advice received. METHODS: Semi-structured interviews were conducted by telephone 7-10 days after contact with one inner city GP co-operative. RESULTS: A total of 47 telephone consultations were followed up with an interview. Of these, 23 (48.9%) callers had expected to be offered a home visit when they called. Reasons for wanting a home visit were either to do with the nature of the condition and its perceived severity, problems in being able to attend the primary care centre and the risks of travel, or because of problems in communicating over the telephone. Satisfaction with telephone consultations centred mostly on the doctor being able to provide reassurance and give adequate time to allay concerns. The most common reasons given for dissatisfaction were the caller feeling that the doctor could not make a correct diagnosis without having seen the patient, or the caller being made to feel that they were wasting the doctor's time. Many patients were anxious about their ability to describe symptoms over the telephone, or understand and follow the advice that they received. CONCLUSIONS: There appears to be a need for patients to be better informed about the service they can expect to receive from GP co-operatives. Recent developments such as NHS Direct may have an influence on the telephone consultation rate to GP co-operatives.

A qualitative study of older people's views of out-of-hours services.

BACKGROUND: Out-of-hours primary care services continues to change with the growth of general practitioner (GP) co-operatives and the more recent development of NHS Direct. While older people are more likely to have increased needs for such services, evidence suggests that they are reluctant users of GP out-of-hours services. AIM: To explore older people's experiences and perceptions of different models of general practice out-of-hours services. DESIGN OF STUDY: Focus group methodology, with qualitative data analysis undertaken using a grounded theory (Framework) approach. SETTING: Thirty people aged between 65 and 81 years old from community groups based in south east London. METHOD: Four focus groups were held, each with between five and 12 participants. Each focus group session lasted 90 minutes and was audiotape-recorded with the permission of the participants. The tapes were transcribed verbatim. RESULTS: Two related themes were identified. First, attitudes to health and healthcare professionals with reference to the use of health services prior to the establishment of the NHS, a stoical attitude towards health, and not wanting to make excessive demands on health services. Second, the experience of out-of-hours care and the perceived barriers to its use, including the use of the telephone and travelling at night. Participants preferred contact with a familiar doctor and were distrustful of telephone advice, particularly from nurses. CONCLUSIONS: Older people appear reluctant to make use of out-of-hours services and are critical of the trend away from out-of-hours care being delivered by a familiar GP. With increasing numbers of older people in the population it is important to consider steps to address their reluctance to use out-of-hours and telephone advice services, particularly those based around less personal models of care.

Ornamental plumage does not signal male quality in red-billed queleas.

Sexually selected ornaments often function as condition-dependent signals of quality (or 'indicators'). When ornamentation is costly, only high-quality individuals can afford to produce the most elaborate signals. The plumage ornamentation of male red-billed queleas, Quelea quelea, is an ideal candidate for an indicator because it is continuously variable, conspicuous, sexually dimorphic, is displayed only during breeding and is partially based on carotenoid pigmentation. However, I show here that quelea plumage is not an indicator because first, plumage colour is not correlated with physical condition or age; second, plumage colour is a genetically determined phenotype that is unresponsive to environmental variation; third, different plumage characters have bimodal distributions; fourth, plumage characters vary independently of one another; and finally, plumage colour is not correlated with reproductive success. To my knowledge, this is the first demonstration of non-condition dependence in colourful and sexually dimorphic breeding ornamentation. Instead, plumage variation may function as a sexually selected signal of individual identity among territorial males that nest in huge, densely packed and highly synchronized colonies.

Sexual harassment in the veterinary academic environment.

OBJECTIVE: To survey faculty and house officers of clinical departments of colleges of veterinary medicine (CVM) to identify characteristics of sexual harassment (SH) in the veterinary academic environment, to report the opinions of survey respondents on how SH is being handled, and to determine how the process can be improved at veterinary academic institutions. PROCEDURE: On the basis of lists obtained from 25 CVM, a survey was mailed to 1,294 academic veterinarians. Four hundred seventy-eight completed surveys were returned. RESULTS: The prevalence of SH in the population of respondents was 31%. Nonphysical forms of SH were reported 6 times as often as physical forms of harassment, with the most common type reported being offensive sexual comments and unwanted attention. Fear of reprisal was the most prevalent reason cited by respondents for not confronting the harasser. Survey respondents rated the following as very important to improve the system of dealing with SH at their academic institution: guarantee of protection from retaliation, assurance of confidentiality, clear explanation of what will happen to you, and a clearer definition of SH. CONCLUSION: A clear definition of SH is the first step in preventing SH. Other cited steps include professional development programs to educate the academic population as to what constitutes SH, inform the entire academic population what the institution's SH policy is, and enforce this policy with sensitivity, fairness, confidentiality, and quick resolve to protect the victim.
