RESUMO
OBJECTIVE: Accurate and up-to-date figures of the cost of community-acquired pneumonia (CAP) hospitalization are needed to understand the associated economic burden for public health decision-makers. Recent estimates are lacking, and previously published estimates differ markedly. Our objective was to estimate the current mean cost to the UK National Health Service (NHS) for adult hospitalized CAP. METHODS: All CAP hospitalizations in 2019 for those aged ≥18 years were identified from English Hospital Episode Statistics (HES). Each hospitalization was mapped to the tariff cost paid to the care provider within the NHS, including critical care costs and accounting for length of stay and complexity of the case. Mean hospitalization costs were estimated in total and in individuals with defined underlying comorbidities. RESULTS: A mean cost of £3,904 was estimated for 187,251 CAP admissions providing a total cost of approximately £731 million per annum. The mean cost was £3,402, excluding critical care costs, and £11,654 for critical care episodes in the 4.4% of admissions receiving this care. Groups at high risk of CAP had higher mean costs, ranging from £4,458 for people with diabetes to £5,215 for those with heart disease aged <65 years and £4,356 for those with heart disease to £4,751 for those with liver disease aged >65 years who comprised 74.3% of admissions overall. CONCLUSION: This estimate of the cost of hospitalization for CAP from the total population and in those with certain underlying comorbidities will allow a valid understanding of the cost-benefit of vaccination and evidence-based prioritization of pneumococcal vaccination to those at highest risk.
Community-acquired pneumonia (CAP) is a disease that is most commonly caused in England by the bacterium Streptococcus pneumoniae, which infects patients outside of a hospital. Patients who suffer from CAP often require hospitalization, which incurs a cost to the UK National Health Service (NHS). The goal of this study was to establish the annual cost of hospitalized CAP.The researchers used England's national healthcare database, known as Hospital Episodes Statistics (HES), to select all adults in England who were hospitalized for CAP in 2019. For the 187,251 patients hospitalized, an average cost of £3,904 per person was estimated, amounting to a total cost of £731 million per year to the NHS. Most people admitted to hospital with CAP were at risk for the disease (due to factors such as increased age or presence of another disease) and the cost of treatment for this subgroup was disproportionately larger than that for treatment of patients not at risk. Furthermore, while approximately 5% of patients admitted for CAP received critical care during treatment, the average cost for these patients was over £8,000 higher than for those outside this subsection.The costs of hospitalization reported in this analysis were higher than previously estimated. The researchers highlighted weaknesses in other studies and limitations of the current study which could explain the difference. This work provides up-to-date figures for the cost of treating CAP in hospital in England. Public health decision-makers can use these estimates to determine the cost-benefit of vaccines that can help protect against important causes of CAP, particularly vaccines that target S. pneumoniae.

The incidence of metastases following neck dissection in the apparent lymph node negative neck in oral cancer is between 7% and 33%; early resection of cervical metastases may well increase survival. Modern imaging techniques can reduce the yield of previously undiagnosed metastatic nodes in elective neck dissection (END). An audit of 112 consecutive cases was conducted to determine the proportion of undiagnosed nodal metastases, after END. There were neck metastases in 10 cases (9%), which were mainly (but not all) micrometastic. The 20% likelihood of nodal metastases was only apparent in primary tumours greater than 6 mm thick. The length of inpatient stay was increased from 3.7 to 16.5 days with free vascularised transfer. There were complications including cranial nerve damage. There were two peri-operative deaths. No ipsilateral neck failures occurred, median follow up was 937 days. To reduce unnecessary END, resection can be undertaken as a prior procedure, subsequently only carrying out END on tumours greater than 6 mm, or with unfavourable tumour characteristics.

BACKGROUND: Sentinel lymph node (SLN) biopsy is an accurate staging modality in early oral squamous cell carcinoma (OSCC), but its accuracy relies on labor-intensive histopathology protocols. We sought to determine whether serial step sections with immunohistochemistry (SSSIHC) at narrow intervals of the entire SLN are required to accurately exclude metastasis. METHODS: Consecutive SLN biopsies over a 13-year period were retrospectively evaluated. If the index section was negative for carcinoma, the entire SLN was subjected to SSSIHC at 150 µm intervals. The first section level and total number of section levels to contain carcinoma were recorded. RESULTS: One hundred and eighteen SLN+ from 90 patients were included. SSSIHC upstaged the nodal status in 19.5% of patients. Metastasis was identified in 16.7% and 10.2% beyond section levels 4 and 6, respectively. Among SLNs requiring SSSIHC, 47.5% contained carcinoma in a single section level. CONCLUSION: SSSIHC of the entire SLN at 150 µm intervals are required to identify occult metastasis in OSCC.

BACKGROUND: We conducted a large international study to estimate fractions of head and neck cancers (HNCs) attributable to human papillomavirus (HPV-AFs) using six HPV-related biomarkers of viral detection, transcription, and cellular transformation. METHODS: Formalin-fixed, paraffin-embedded cancer tissues of the oral cavity (OC), pharynx, and larynx were collected from pathology archives in 29 countries. All samples were subject to histopathological evaluation, DNA quality control, and HPV-DNA detection. Samples containing HPV-DNA were further subject to HPV E6*I mRNA detection and to p16(INK4a), pRb, p53, and Cyclin D1 immunohistochemistry. Final estimates of HPV-AFs were based on HPV-DNA, HPV E6*I mRNA, and/or p16(INK4a) results. RESULTS: A total of 3680 samples yielded valid results: 1374 pharyngeal, 1264 OC, and 1042 laryngeal cancers. HPV-AF estimates based on positivity for HPV-DNA, and for either HPV E6*I mRNA or p16(INK4a), were 22.4%, 4.4%, and 3.5% for cancers of the oropharynx, OC, and larynx, respectively, and 18.5%, 3.0%, and 1.5% when requiring simultaneous positivity for all three markers. HPV16 was largely the most common type. Estimates of HPV-AF in the oropharynx were highest in South America, Central and Eastern Europe, and Northern Europe, and lowest in Southern Europe. Women showed higher HPV-AFs than men for cancers of the oropharynx in Europe and for the larynx in Central-South America. CONCLUSIONS: HPV contribution to HNCs is substantial but highly heterogeneous by cancer site, region, and sex. This study, the largest exploring HPV attribution in HNCs, confirms the important role of HPVs in oropharyngeal cancer and drastically downplays the previously reported involvement of HPVs in the other HNCs.

The management of pain is an important aspect of an orthopaedic nurse's role. The aim of this paper is to use an individual case study to demonstrate the role of an out-patient orthopaedic nurse in the identification, assessment and management of pain. This paper describes how pain was identified and managed for a patient in the orthopaedic outpatient department, highlighting that pain and its management are not isolated to the in-patient setting. The case study illustrates the importance of recognising pain and taking into account the numerous factors that can influence pain perception. The assessment of an individual patient's pain led to obtaining help from the Acute Pain Team which led to improvement in the patient's pain management and quality of life. The nursing team reflected and discussed the issues identified by this case study which led to changes in practice being introduced. This has resulted in an increased knowledge of and confidence in pain management within the nursing team and development and improvement of pain management practice within the orthopaedic out-patient department.

BACKGROUND AND PURPOSE: Tumour hypoxia is associated with a poor prognosis in head and neck squamous cell carcinoma (HNSCC), however there is no accepted method for assessing hypoxia clinically. We aimed to conduct a technical validation of a hypoxia gene expression signature using the TaqMan Low Density Array (TLDA) platform to investigate if this approach reliably identified hypoxic tumours. MATERIALS AND METHODS: Tumour samples (n=201) from 80 HNSCC patients were collected prospectively from two centres. Fifty-three patients received pimonidazole prior to surgery. TaqMan Low Density Array-Hypoxia Scores (TLDA-HS) were obtained by quantitative real-time PCR (qPCR) using a 25-gene signature and customised TLDA cards. Assay performance was assessed as coefficient of variation (CoV). RESULTS: The assay was sensitive with linear reaction efficiencies across a 4 log(10) range of inputted cDNA (0.001-10 ng/µl). Intra- (CoV=6.9%) and inter- (CoV=2.0%) assay reproducibility were excellent. Intra-tumour heterogeneity was lower for TLDA-HS (23.2%) than for pimonidazole (67.2%) or single gene measurements of CA9 (62.2%), VEGFA (45.0%) or HIG2 (39.4%). TLDA-HS in HNSCC cell lines increased with decreasing pO(2). TLDA-HS correlated with Affymetrix U133 Plus 2.0 microarray HS (p<0.01) and positive pimonidazole scores (p=0.005). CONCLUSIONS: Gene expression measurements of hypoxia using a 25-gene signature and TLDA cards are sensitive, reproducible and associated with lower intra-tumour heterogeneity than assaying individual genes or pimonidazole binding. The approach is suitable for further assessment of prognostic and predictive capability in clinical trial material.

BACKGROUND: Shiga toxin-producing Escherichia coli (STEC) are an important cause of gastroenteritis in Australia and worldwide and can also result in serious sequelae such as haemolytic uraemic syndrome (HUS). In this paper we describe the epidemiology of STEC in Australia using the latest available data. METHODS: National and state notifications data, as well as data on serotypes, hospitalizations, mortality and outbreaks were examined. RESULTS: For the 11 year period 2000 to 2010, the overall annual Australian rate of all notified STEC illness was 0.4 cases per 100,000 per year. In total, there were 822 STEC infections notified in Australia over this period, with a low of 1 notification in the Australian Capital Territory (corresponding to a rate of 0.03 cases per 100,000/year) and a high of 413 notifications in South Australia (corresponding to a rate of 2.4 cases per 100,000/year), the state with the most comprehensive surveillance for STEC infection in the country. Nationally, 71.2% (504/708) of STEC infections underwent serotype testing between 2001 and 2009, and of these, 58.0% (225/388) were found to be O157 strains, with O111 (13.7%) and O26 (11.1%) strains also commonly associated with STEC infections. The notification rate for STEC O157 infections Australia wide between 2001-2009 was 0.12 cases per 100,000 per year. Over the same 9 year period there were 11 outbreaks caused by STEC, with these outbreaks generally being small in size and caused by a variety of serogroups. The overall annual rate of notified HUS in Australia between 2000 and 2010 was 0.07 cases per 100,000 per year. Both STEC infections and HUS cases showed a similar seasonal distribution, with a larger proportion of reported cases occurring in the summer months of December to February. CONCLUSIONS: STEC infections in Australia have remained fairly steady over the past 11 years. Overall, the incidence and burden of disease due to STEC and HUS in Australia appears comparable or lower than similar developed countries.

Nutritious, safe, affordable, and enjoyable food is a fundamental prerequisite for health. As a nation, Australia is currently classified as food secure with the domestic production exceeding domestic consumption of most major food groups. The domestic system is almost self-sufficient in terms of nutritious plant foods, although these foods have seen steady higher price increases relative to other foods, with nutrition equity implications. However, the viability of Australia's food security sits counter to the continued presence of a stable and supportive climate. This article reviews the current state of science concerning the interface between climate change, food systems, and human health to reveal the key issues that must be addressed if Australia is to advance human health and sustainable food systems under a changing climate.

BACKGROUND: Early identification in primary care settings of individuals with, or at-risk of, developing persistent pain, is important to limit development of disability. There is little information to assist primary care providers to choose or deliver relevant, efficient, and soundly constructed assessment instruments for this purpose. OBJECTIVE: We recently published the findings of a literature review, which produced a compendium of assessment instruments to identify adults with, or at-risk of developing, persistent pain of noncancer origin. This paper reports on instruments opportunistically identified during this review which may be appropriate to primary health care settings for early identification of such patients. RESULTS: One hundred sixteen potentially useful instruments were initially identified in the review, measuring pain severity, psychological distress, functional capacity, quality of life or multidimensional constructs of persistent pain. Following a series of steps, 45 instruments were shortlisted, with sound clinical utility and strong psychometric properties. Of these, 16 instruments were appropriate to primary health care settings because of simple wording, brief items, short administration time, and ease of scoring. CONCLUSION: No one assessment instrument captured all constructs of persistent pain. The 16 instruments provide a broad choice for primary care clinicians to assist with early identification of adults at risk of, or with persistent pain.
RESUMO
BACKGROUND: Early identification of individuals at risk of developing persistent pain is important to decrease unnecessary treatment costs and disability. However there is scant comprehensive information readily available to assist clinicians to choose appropriate assessment instruments with sound psychometric and clinical properties. OBJECTIVE: A national insurer commissioned the development of a compendium of assessment instruments to identify adults with, or at-risk of developing, persistent pain. This paper reports on the instrument identification and review process. METHODS: A comprehensive systematic literature review was undertaken of assessment instruments for persistent pain of noncancer origin, and their developmental literature. Only assessment instruments which were developed for patients with pain, or tested on them, were included. A purpose-built 'Ready Reckoner' scored psychometric properties and clinical utility. RESULTS: One hundred sixteen potentially useful instruments were identified, measuring severity, psychological, functional and/or quality of life constructs of persistent pain. Forty-five instruments were short-listed, with convincing psychometric properties and clinical utility. There were no standard tests for psychometric properties, and considerable overlap of instrument purpose, item construct, wording, and scoring. CONCLUSION: No one assessment instrument captured all the constructs of persistent pain. While the compendium focuses clinicians' choices, multiple instruments are required for comprehensive assessment of adults with persistent pain.
