Comparative StudyComparison of recommendations for radiotherapy from two contemporaneous thoracic multidisciplinary meeting formats: co-located and video conference.
Thoracic multidisciplinary meetings (TMDM) are a key component of lung cancer patient management. The optimal design, organisation and function of TMDM are uncertain, and different models may serve different purposes. In the Auckland/Northland region, there are two contemporaneous weekly TMDM using different formats; one is a co-located TMDM (C-TMDM), and the other is a video conference TMDM (V-TMDM) connecting different locations. ⋯ The similar results from the different formats of TMDM indicate that cases discussed with the use of e-health technologies are not disadvantaged with respect to recommended therapy nor in the appropriateness of decisions of the TMDM. Use of such technology may reduce the existing disparities in health outcomes between urban and rural patients.

Nutritional status of long-term patients in the acute care setting.
The nutritional status of 926 patients (51.4% female) at an acute tertiary private hospital with a length of stay ≥14 days was assessed using Subjective Global Assessment. The prevalence of malnutrition was 42.5% (37.2% length of stay of 14-27 days, 51.6% ≥28 days). From logistic regression analysis, length of stay and age were independent predictors of malnutrition. It is important that the nutritional status of longer stay patients is monitored and appropriate nutrition support is commenced.

SPECT ventilation perfusion scanning with the addition of low-dose CT for the investigation of suspected pulmonary embolism.
Single-photon emission computed tomography (SPECT) ventilation perfusion (V/Q) scanning with low-dose computed tomography (LDCT) is an emerging imaging technique for investigation of suspected pulmonary embolism (PE). We aimed to estimate diagnostic utility of the combined technique using results from all patients referred in 2009 compared with final diagnosis and 6-month follow-up status. ⋯ LDCT was abnormal in 43 (41%) patients, including 41 patients who had negative SPECT V/Q. In 29 (27%) patients, LDCT provided information on alternative pathologies that accounted for presenting symptoms, and the combined technique had a diagnostic yield of 52%.

Blastocystis subtypes in symptomatic and asymptomatic family members and pets and response to therapy.
Blastocystis is a common, enteric parasite. The pathogenicity of the organism is uncertain, but subtypes (ST) 1 and 3 have been reported more likely to cause irritable bowel-like symptoms. ⋯ Conventional therapy is ineffective for symptomatic Blastocystis infection. The high prevalence of Blastocystis infection within households suggested transmission between humans and their pets. Subtyping analysis of SSU rDNA alone in Blastocystis does not appear to predict pathogenicity.
