RESUMO
Optimising decision-making in elderly patients is becoming increasingly urgent. We analysed treatment decisions and course of therapy for patients with lung cancer in different age categories: <65, 65-75, and 75 years and older. About 349 patients with lung cancer (median age 67.8 years), discussed at the multidisciplinary team meeting in the Diakonessenhuis Utrecht, the Netherlands, were reviewed. Multidisciplinary decision-making and subsequent clinical course were extracted from medical files. We found that 39% of eligible patients older than 75 years of age started treatment with chemotherapy compared to 80% of the younger patients (<65 and 65-75). When patients did receive chemotherapy, primary and secondary treatment adaptations were effectuated in 58%: for patients aged <65 in 49%, for patients aged 65-75 and >75 years in 66%. For 44% of all patients treated with chemotherapy, unplanned hospital admissions were required: in 42% for the patients <65, in 52% for those aged 65-75 and in 27% for >75 years. The decision-making process and course of treatment for lung cancer vary per age category. In particular, patients between 65 and 75 years of age might be more frail than initially thought. Age and frailty are important characteristics that need more attention.

The quality of medical care delivered to patients with cancer near the end of life is a significant issue. Previous studies have defined several areas suggestive of aggressive cancer treatment as potentially representing poor quality care. The primary objective of current analysis was to examine chemotherapy and healthcare utilisation in the last 3 months of life among patients with cancer that received palliative chemotherapy. Patients were selected from the hospital administration database of the Diakonessenhuis Utrecht, the Netherlands. Data were extracted from the medical files. A total of 604 patients were included for analysis (median age: 64 years). For 300 patients (50%) chemotherapy was given in the last 3 months (CT+). For 76% (n = 229) of CT+ patients unplanned hospital admissions were made in these last 3 months, compared to 44% (n = 133) of CT- patients (p < .001). Visits to the emergency room in last 3 months were made by 67% (n = 202) of CT+ patients compared to 43% (n = 132) of CT- patients (p < .001). Healthcare consumption was significantly higher in patients who received chemotherapy in the last 3 months of life. Being able to inform our patients about these aspects of treatment can help to optimise both the quality of life and the quality of dying in patients with cancer.

BACKGROUND: With the development of new antiviral agents for influenza, the urge for rapid and reliable diagnosis of influenza becomes increasingly important. Respiratory virus infections are difficult to distinguish on clinical grounds. General practitioners (GPs) however, still depend on their clinical judgement. AIM: To evaluate the importance of clinical symptoms in the diagnosis of influenza virus infection. DESIGN OF STUDY: A multicentre questionnaire study. SETTING: Eighty-one patients from 14 general practices. METHOD: Patients with fever and at least one constitutional symptom and one respiratory symptom were included. A questionnaire with the medical history and clinical symptoms was completed and a combined nose-throat swab was taken. Virus culture, rapid culture, and polymerase chain reaction (PCR) amplification were performed on each specimen. Multivariate analysis was used to obtain the best predictive model. RESULTS: By using PCR, an increase was seen in the detection of the viral pathogens compared with the results of culture. In 42 out of 81 patients PCR was positive for influenza. A positive predictive value (PPV) of 75% was observed for the combination of headache at onset, feverishness at onset, cough, and vaccination status during the period of increase influenza activity. Criteria used by the ICHPPC-2 resulted in a PPV of 54%. The PPV for diagnosis made by the GP was 76%. CONCLUSION: Although influenza is difficult to diagnose on clinical grounds, the GPs in this study were able to diagnose influenza as such more accurately on their judgement than by the other criteria.

Since influenza viruses can cause severe illness, timely diagnosis is important for an adequate intervention. The available rapid detection methods either lack sensitivity or require complex laboratory manipulation. This study describes a rapid, sensitive detection method that can be easily applied to routine diagnosis. This method simultaneously detects influenza viruses A and B in specimens of patients with respiratory infections using a TaqMan-based real-time PCR assay. Primers and probes were selected from highly conserved regions of the matrix protein gene of influenza virus A and the hemagglutinin gene segment of influenza virus B. The applicability of this multiplex PCR was evaluated with 27 influenza virus A and 9 influenza virus B reference strains and isolates. In addition, the specificity of the assay was assessed using eight reference strains of other respiratory viruses (parainfluenza viruses 1 to 3, respiratory syncytial virus Long strain, rhinoviruses 1A and 14, and coronaviruses OC43 and 229E) and 30 combined nose and throat swabs from asymptomatic subjects. Electron microscopy-counted stocks of influenza viruses A and B were used to develop a quantitative PCR format. Thirteen copies of viral RNA were detected for influenza virus A, and 11 copies were detected for influenza virus B, equaling 0.02 and 0.006 50% tissue culture infective doses, respectively. The diagnostic efficacy of the multiplex TaqMan-based PCR was determined by testing 98 clinical samples. This real-time PCR technique was found to be more sensitive than the combination of conventional viral culturing and shell vial culturing.

Respiratory syncytial virus (RSV) accounts for the majority of respiratory virus infections, producing high mortality rates in immunocompromised patients with hematologic malignancies. The available methods for the rapid detection of RSV by antigen detection or PCR either lack sensitivity, require complex laboratory manipulation, or have not been evaluated in this patient population. To assess the applicability of a TaqMan-based real-time PCR technique for the detection of RSV A and B in immunocompromised adults, we developed a rapid, sensitive detection method that simultaneously detects RSV A and B and can be applied in routine diagnostics. The specificity of the assay was assessed using a panel of reference strains of other respiratory viruses and RSV. Electron microscopy-counted stocks of RSV A and B were used to develop a quantitative PCR format. Eleven copies of viral RNA could be detected for RSV A strain Long, and 14 copies could be detected for RSV B strain 9320, corresponding to 50% tissue culture infective doses of 0.86 and 0.34, respectively. The assay was evaluated on 411 combined nose and throat swabs derived from immunocompromised adults with or without signs of respiratory tract infection. The diagnostic efficacy of the TaqMan PCR determined on the clinical samples showed that this real-time PCR technique was substantially more sensitive than the combination of conventional viral culture and shell vial culture. None of the clinical specimens derived from patients without signs of respiratory illness were found to be positive for RSV by real-time TaqMan PCR.
