Food Insecurity and Health-Related Quality of Life: A Cross-Sectional Analysis of Older Adults in Florida, U.S.

Individuals 65 years or older will comprise an estimated 20.0% of the U.S. population by 2030. This study investigated the association between food insecurity and health-related quality of life (HRQoL) among an older adult population (n = 234). HRQoL was measured using Healthy Days, a validated survey tool developed by the Centers of Disease Control and Prevention. Food-insecure individuals were more likely to report ≥14 physically unhealthy days (OR = 1.49, 95% CI 0.47-4.78) and ≥14 days with activity limitations (OR = 4.07, 95% CI 0.68-24.1). Although nonsignificant, the findings highlight food insecurity as a potentially important social determinant of health throughout the life course, including at an older age.

Antimicrobial-resistant Faecal Organisms in Algae Products Marketed as Health Supplements.

Dietary supplements are increasingly popular in Irish society. One of these is blue-green algae which is used with a variety health benefits in mind. A batch of Chlorella powder was found to be contaminated with Salmonella species in Ireland in 2015. This prompted additional testing of a total of 8 samples of three different products (Chlorella, Spirulina and Super Greens), for other faecal flora and antimicrobial resistance in any bacteria isolated. All 8 samples cultured enteric flora such as Enterococci, Enterobacteriaceae and Clostridium species. Antimicrobial susceptibility testing revealed one isolate with extended-spectrum ?-lactamase (ESBL) activity and one with carbapenemase activity. Clinicians caring for vulnerable patients should be aware of the potential risk of exposure to antimicrobial resistant bacteria associated with these products.

Dissemination of clonally related multidrug-resistant Klebsiella pneumoniae in Ireland.

In October 2012, an outbreak of gentamicin-resistant, ciprofloxacin non-susceptible extended-spectrum ß-lactamase (ESBL)-producing Klebsiella pneumoniae occurred in a neonatal intensive care unit in Ireland. In order to determine whether the outbreak strain was more widely dispersed in the country, 137 isolates of K. pneumoniae with this resistance phenotype collected from 17 hospitals throughout Ireland between January 2011 and July 2013 were examined. ESBL production was confirmed phenotypically and all isolates were screened for susceptibility to 19 antimicrobial agents and for the presence of genes encoding bla TEM, bla SHV, bla OXA, and bla CTX-M; 22 isolates were also screened for bla KPC, bla NDM, bla VIM, bla IMP and bla OXA-48 genes. All isolates harboured bla SHV and bla CTX-M and were resistant to ciprofloxacin, gentamicin, nalidixic acid, amoxicillin-clavulanate, and cefpodoxime; 15 were resistant to ertapenem, seven to meropenem and five isolates were confirmed as carbapenemase producers. Pulsed-field gel electrophoresis of all isolates identified 16 major clusters, with two clusters comprising 61% of the entire collection. Multilocus sequence typing of a subset of these isolates identified a novel type, ST1236, a single locus variant of ST48. Data suggest that two major clonal groups, ST1236/ST48 (CG43) and ST15/ST14 (CG15) have been circulating in Ireland since at least January 2011.

Twenty years of SHIELD: decreasing incidence of occupational asthma in the West Midlands, UK?

INTRODUCTION: Since 2000 a decline in the incidence of occupational asthma (OA) has been reported in the UK and Europe. We aimed to describe and account for trends in the incidence of OA in the West Midlands, UK using annual notification data from the SHIELD voluntary surveillance scheme over the period 1991-2011. METHODS: All notifications to the SHIELD database between January 1991 and December 2011 were identified, along with patients' demographic data, occupations, causative agents and confirmatory tests. Annual notifications were scaled to give an annual count per million workers, giving a measure of incidence, and also standardised against those of bakers' asthma. Non-parametric analyses were undertaken between annual incidence and time (years) for common causative agents using (1) a negative binomial regression univariate model and (2) a logistic regression model calculating annual reporting ORs. A step-change analysis was used to examine time points at which there were marked reductions in incidence. RESULTS: A decrease in annual incidence of OA was observed over the study period (incident rate ratio=0.945; 95% CI 0.933 to 0.957; p<0.0001), an effect that was lost after standardising for bakers' asthma. Decreases in incidence were seen for most common causative agents, with only cleaning product-related OA increasing over 21 years. Marked fall in incidence was seen in 2004 for isocyanates, and in 1995 for latex. Most notifications came from a regional specialist occupational lung disease unit, with notifications from other sites falling from 16 cases/million workers/annum in 1995 to 0 in 2004. CONCLUSIONS: Reporter fatigue and increasing under-recognition of OA are both factors which contribute to the apparent fall in incidence of OA in the West Midlands. There is a future need for interventions that enable health professionals to identify potential cases of OA in the workplace and in healthcare settings.

Dermatological postoperative patient information leaflets: is it time for more uniformity?

INTRODUCTION: Patient information leaflets (PILs) are an important source of information for patients postoperatively. There are currently no nationally agreed standards by dermatologists for postoperative advice following skin surgery. AIM: To assess the common themes and areas of variation in advice given in PILs after skin surgery across all National Health Service (NHS) hospitals in England and Wales. METHODS: All acute trusts in England (n = 159) and local health boards in Wales (n = 7) were requested to provide their postoperative dermatological PILs for general sutured wound care or excision biopsy. Eight preselected parameters were assessed: minimum dressing duration, duration of pressing on a bleeding wound, postoperative analgesia, explanation of infection signs, application of petroleum jelly, scarring, whom to contact if there is a problem, and the recommended postoperative time for abstaining from active exercise. RESULTS: PILs were received from 137 different dermatology departments belonging to 127/166 (76.5%) organisations across England and Wales. Of these, 102 PILs gave a specific duration for dressings: 45/102 (44.1%) advised a minimum of 48 h, but 28/102 (27.5%) recommended leaving dressings in place until suture removal. Regarding duration of pressing on a bleeding wound, 117 PILs gave advice, with the most common recommendation being 15 min (30/117, 25.6%), followed closely by 10 min (26/117, 22.2%). Of the 137 PILs received, 125 gave advice regarding postoperative analgesia, with paracetamol alone being the most common recommendation (24/125, 19.2%). For the remaining parameters, 111/137 (81.0%) PILs described ≥ 2 signs of infection, 42/137 (30.7%) recommended the application of petroleum jelly, 65/137 (47.4%) mentioned scarring, 137/137 (100%) highlighted whom to contact if there were postoperative problems and 87/137 (63.5%) PILs gave advice regarding postoperative abstinence from active exercise. CONCLUSIONS: The advice given in dermatology postoperative PILs across England and Wales is highly variable. A nationally agreed template or set of postoperative advice should be considered to improve consistency.

Therapeutic and prophylactic ethanol lock therapy in patients with bleeding disorders.

Obtaining a reliable venous access is a limiting factor for early initiation of clotting factor prophylaxis and immune tolerance induction. To circumvent this issue, central venous access devices (CVADs) are increasingly being used. Catheter-related infections (CRIs) remain the primary complication of insertion of CVAD. Thus, newer strategies for treatment and prevention of CRI are needed. Ethanol lock therapy (ELT) has been used to treat and prevent CRI in non-bleeding disorder patients. The aim of this study was to assess the efficacy of ELT in treating and preventing CRI in bleeding disorder patients. The medical charts of patients with bleeding disorders who underwent ELT for antimicrobial resistant CRIs were reviewed and data were analysed. ELT was effective in catheter salvage in 87% of patients with antimicrobial resistant CRI by a wide variety of pathogens. Prophylactic therapy with ethanol lock was associated with catheter dysfunction especially in mediports. ELT should be considered prior to removal of catheters in bleeding disorder patients with resistant CRIs. Further studies are needed for using prophylactic ethanol lock in prevention of CRIs in bleeding disorder patients.

First report of IMI-1-producing colistin-resistant Enterobacter clinical isolate in Ireland, March 2013.

We report the first case in Ireland of an IMI-1 carbapenemase-producing Enterobacter asburiae, which was resistant to both colistin and fosfomycin. The circumstances under which this isolate was acquired were unclear. Several reports of IMI-producing Enterobacter spp. have emerged in recent years, and colistin resistance in Enterobacteriaceae is also increasingly reported. Laboratories should be aware of the unusual antibiograms of IMI-producing isolates.

Agents and trends in health care workers' occupational asthma.

BACKGROUND: There is a disproportionately high number of cases of work-related asthma occurring in health care occupations due to agents such as glutaraldehyde, latex and cleaning products. AIMS: To understand the causes and measure trends over time of occupational asthma (OA) in health care workers (HCWs). METHODS: We reviewed OA notifications from the Midland Thoracic Society's Surveillance Scheme of Occupational Asthma (SHIELD) database in the West Midlands, UK, from 1991 to 2011 and gathered data on occupation, causative agent and annual number of notifications. RESULTS: There were 182 cases of OA in HCWs (median annual notifications = 7; interquartile range [IQR] = 5-11), representing 5-19% of annual SHIELD notifications. The modal annual notification was 20 (in 1996); notifications have declined since then, in line with total SHIELD notifications. The majority of cases (136; 75%) occurred in nursing, operating theatre, endoscopy and radiology staff. The most frequently implicated agents were glutaraldehyde (n = 69), latex (n = 47) and cleaning products (n = 27), accounting for 79% of the 182 cases. Cleaning product-related OA was an emerging cause with 22 cases after 2001 and only 5 cases between 1991 and 2000. CONCLUSIONS: Control measures within the UK National Health Service have seen a decline in OA in HCWs due to latex and glutaraldehyde, though OA remains a problem amongst HCWs exposed to cleaning products. Continuing efforts are required to limit the number of cases in this employment sector.

Audit of the recording of occupational asthma in primary care.

BACKGROUND: Occupational asthma (OA) remains common; 1 in 10 cases of adult-onset asthma is due to work. Health outcomes are better with early diagnosis, but there is considerable delay, largely due to lack of enquiry about work effect in primary care. National guidelines (2008) recommend asking two screening questions, which together have a high sensitivity in identifying OA. AIMS: To audit how working-age asthmatics are currently screened for OA in a local primary care population. METHODS: An audit of the electronic patient records of working-age asthmatics, from four Birmingham primary care practices was undertaken. Practice-level data (list size, gender, prevalence of asthma and OA and socio-economic status) and patient-level data (gender, age, onset, occupation and work-effect enquiry and lung function) were collected. RESULTS: The total practice population was 27,295 of which 17,564 (64%) were of working age. The audit sample was 396 of whom 49% were male. The prevalence of asthma in working-age adults was 12% (8-15%) and the prevalence of OA in working-age asthmatics was 0.3% (0-0.8%). Occupation was recorded in only 55/396 (14%) cases with very few (2) documented within the asthma-review template. Occupation was only recorded in 13/55 adult-onset asthmatics in high-risk occupations. Of 396, 9 (2%) had any work-effect enquiry and 4 patients had work-effect enquiry at diagnosis in those with traceable notes (n = 117). CONCLUSIONS: The prevalence of OA was low, suggesting under-diagnosis plus under-reporting in primary care. Occupation and work-effect enquiry is lacking despite guidelines for identifying OA. Existing electronic templates for recording asthma review could be modified to include these elements.

A prospective trial of the effects of isotretinoin on quality of life and depressive symptoms.

BACKGROUND: Isotretinoin is an efficacious treatment for acne, but has been controversially linked with depression. OBJECTIVES: This study aimed to examine the effects of isotretinoin on quality of life(QoL) and depression using a prospective design. METHODS: The WHOQOL-BREF QoL measure and Centre for Epidemiological Studies Depression Scale were administered to consecutive outpatients with acne who were prescribed either isotretinoin (n = 65) or antibiotic treatment (n = 31).Patients and physicians rated acne severity independently. Groups were compared at baseline with a matched community sample (n = 94) and measurements repeated at 3 months for treatment groups. RESULTS: There were no differences between the three groups at baseline in terms of age, gender, depression or overall QoL. Acne was more severe in the treatment groups (P < 0·001). Depression was negatively correlated with QoL (P < 0·001)and hence was included as a covariate in repeated-measures analyses of QoL.Acne improved over time in both treatment groups (F = 48·2, P < 0·001). There was no detectable deterioration in depression score in either group (F = 1·1, not significant). QoL in the physical and social domains improved (P < 0·001) while psychological and environmental QoL was unchanged over time. The improvement in social QoL was greater in the isotretinoin group (P < 0·05). Those patients with higher baseline depression scores showed greater improvements in physical, psychological and social QoL (P < 0·001). CONCLUSIONS: Treatment of acne improves QoL, particularly in those with more depressive symptoms at the outset. Mood deterioration was not detected, but the possibility of subtle or rare mood effects of isotretinoin cannot be ruled out.

Diagnostic tests for tuberculous pleural effusion.

The investigation of pleural effusion has been greatly assisted by advancements in pleural fluid analysis. In the case of tuberculous pleural effusion, diagnosis traditionally requires the demonstration of acid fast bacilli in the pleural space using microbiological or histological techniques. In recent years, there has been progress in pleural fluid analysis in suspected tuberculous effusions, with particular interest in adenosine deaminase and interferon-γ. These individual tests are quite sensitive and specific; however, data are sparse on the benefits that multiple-parameter testing may have when analysed in combination. We reviewed the literature to investigate the evidence for multiple-parameter testing, both biochemical and clinical, in the evaluation of tuberculous effusion.

Quantification of wound oedema after dermatological surgery.

BACKGROUND: Postoperative wound oedema causing increased suture tension is thought to be a possible cause of scars known as suture marks. Quantification of such oedema has not previously been reported in the literature. Measures to accommodate wound oedema may include the adoption of alternative suture techniques and the use of more elastic suture materials. OBJECTIVES: To quantify wound expansion after skin surgery and to identify any contributory factors, and to determine the ability of eight commonly used skin suture materials to stretch under increasing tension. METHODS: Forty consecutive adult patients attending a dermatology department for routine skin surgery in December 2002 were recruited. Details including body site, nature of the lesion excised and dimensions of the open wound were recorded. The distance between entry and exit points of an untied suture at the time of skin surgery was measured and then repeated 24 h postoperatively. The ability of eight different suture materials to stretch when an increasing force was applied was measured by hanging standard weights from the sutures and measuring the suture length for each force applied. RESULTS: Thirty-nine patients completed the study. All wounds expanded postoperatively, with a mean lateral expansion of 1.0 mm. There was a strong association between the width of the unsutured wound after excision and the subsequent wound expansion. Commonly used sutures in skin surgery were found to be relatively inelastic at forces under 0.2 kg. The monofilament Novofil (Davis & Geck, Danbury, CT, U.S.A.) exhibited the greatest degree of stretch of those tested. CONCLUSIONS: There is considerable oedema in the first 24 h after skin surgery, particularly with wider excisions. This needs to be considered when choosing suturing materials and techniques to avoid excessive suture tension.

A systematic approach to the investigation and diagnosis of a unilateral pleural effusion.

Fluid in the pleural space is a common sequela of a wide range of diseases which may be pulmonary, pleural or extrapulmonary. As the differential diagnosis is wide, a systematic approach to investigation and diagnosis is recommended. This review highlights the important features and recommendations for the investigation of a unilateral pleural effusion, a common condition encountered by the general physician. The aim of this study was to assist with a speedy diagnosis of the underlying pathology, using appropriate investigative techniques, while minimising the use of invasive procedures.

Altered natural killer cell subset distributions in resolved and persistent hepatitis C virus infection following single source exposure.

BACKGROUND: Natural killer (NK) cells may be impaired in patients with persistent hepatitis C virus (HCV) infection, but studies to date have yielded inconsistent findings due to patient and virus heterogeneity and difficulties obtaining appropriate controls. AIMS: To overcome these variables, we have examined numbers, phenotypes, cytotoxic activities and cytokine profiles of circulating NK cells from Irish women who acquired infection through administration of HCV genotype 1b-contaminated anti-D immunoglobulin from a single source and matched controls. RESULTS: Comparing 29 women who developed persistent infection with 21 who spontaneously resolved infection and 26 controls, we found that NK cell numbers were consistently lower in the persistently infected group (p = 0.02 and 0.002). This decrease was due to depletions of NK cells expressing low levels of CD56 (CD56(dim) NK cells; p = 0.004 and 0.0001), whilst CD56(bright) NK cells were expanded (p = 0.004 and 0.0001). Compared to HCV resolvers, CD56(dim) NK cells from persistently infected patients less frequently expressed CD16 and more frequently expressed NKG2A/C/E. These phenotypic changes did not significantly affect natural or interleukin-2-induced cytotoxicity by peripheral blood mononuclear cells against K562 and Daudi targets. Greater frequencies of CD56(bright) NK cells from chronic HCV patients produced interferon-gamma compared with HCV responders (p = 0.05) and controls (p = 0.0001) after phorbol ester stimulation in vitro. CONCLUSIONS: Alterations in NK subset distributions in chronic HCV infection may explain why previous reports of impaired NK cell functions were difficult to confirm. Altered NK cell functions may contribute to impaired cellular immune responses and chronicity of disease following HCV infection.

Guidelines on the diagnosis and treatment of pulmonary non-tuberculous mycobacteria infection.

While the prevalence of Mycobacterium tuberculosis continues to decline in the developed world, the same cannot be said for non-tuberculous mycobacteria (NTM). These organisms are increasing in incidence and prevalence throughout the world. This is probably because of a combination of increased exposure, improved diagnostic methods and an increase in the prevalence of risk factors that predispose individuals to infection. Considerable confusion can arise in determining in the wide range of species whether an isolated NTM is in fact a contaminant or a pathogenic organism when isolated in sputum or bronchoalveolar lavage. This confusion combined with increasing requests for advice on the treatment of disease has led to the development of guidelines to assist the clinician in diagnosing and treating infection accurately.

Current status of JACIE accreditation in Europe: a special report from the Joint Accreditation Committee of the ISCT and the EBMT (JACIE).

JACIE (Joint Accreditation Committee of the ISCT and the EBMT) launched its first official inspection programme in January 2004. Since then, 35 centres in Europe have been inspected. Almost all were found to be functioning at a high level of excellence, with the majority having only minor deficiencies in compliance with the standards. In one-third of centres there were more significant deficiencies. The most common deficiencies were in quality management, and a survey of the applicant centres confirmed this was the area where centres experienced most difficulty in preparation for accreditation. Following correction of deficiencies, 28 centres have at the time of writing achieved full accreditation. Implementation of JACIE required a significant investment of time and resources by applicant centres. The majority required at least 18 months to prepare for accreditation and 85% needed to employ a quality manager and/or data manager on an ongoing basis. However, all centres felt their programme had benefited from the implementation of JACIE. In addition to the inspection and accreditation of individual centres, JACIE maintains an educational programme including training courses for inspectors and for centre preparation. JACIE is also working closely with other international organisations working in cellular therapy to develop international standards for all aspects of stem cell transplant. The recent implementation of Directive 2004/23/EC has provided an impetus for the implementation of JACIE in EU member states and in particular the requirements for safety of imported tissues and cells have emphasised the need for global harmonisation.
