BACKGROUND: Over 38,000 new cases of lung cancer occur each year in the UK. Most are diagnosed after initial presentation to primary care, but the relative importance of the various clinical features is largely unknown. METHODS: A population based case-control study was undertaken in all 21 general practices in Exeter, Devon, UK (population 128 700). 247 primary lung cancers were studied in subjects aged over 40 years diagnosed between 1998 and 2002 and 1235 controls matched by age, sex and general practice. The entire primary care record for 2 years before diagnosis was coded using the International Classification of Primary Care-2. Univariable and multivariable conditional logistic regression analyses were used to identify and quantify clinical features independently associated with lung cancer. The main outcome measures were odds ratios and positive predictive values for these variables. RESULTS: Seven symptoms (haemoptysis, loss of weight, loss of appetite, dyspnoea, thoracic pain, fatigue and cough), one physical sign (finger clubbing), and two abnormal investigation results (thrombocytosis and abnormal spirometry) were associated with lung cancer in multivariable analyses, as was cigarette smoking. After excluding variables reported in the final 180 days before diagnosis, haemoptysis, dyspnoea and abnormal spirometry remained independently associated with cancer. CONCLUSIONS: This study provides an evidence base for selection of patients for investigation of possible lung cancer, both for clinicians and for developers of guidelines.
Despite doctors' expectations, non-compliance is common in short-term antibiotic therapy of respiratory tract infections (RTIs). This phenomenon has profound practical implications. It leads to ineffective management, the deterioration of patients' health, hospital admissions, additional costs and the emergence of antibiotic-resistant microorganisms. This article reviews methods of measuring compliance with antibiotics in the outpatient-based management of RTIs and research results. Causes of non-compliance are also discussed. Factors influencing compliance are analysed, as well as practical strategies for addressing non-compliance with antibiotic therapies for RTIs. The influence of the frequency of doses on compliance is particularly stressed, as it has been observed that once daily dosing has almost a 100% compliance rate. As a number of once-daily antibiotic preparations are available now, the possibility of using once-daily schedules for improving compliance in RTI cases is stressed.
BACKGROUND: Influenza vaccination is recommended for asthmatic patients in many countries as observational studies have shown that influenza infection can be associated with asthma exacerbations. However, influenza vaccination has the potential to cause wheezing and adversely affect pulmonary function. While an overview concluded that there was no clear benefit of influenza vaccination in patients with asthma, this conclusion was not based on a systematic search of the literature. OBJECTIVES: The objective of this review was to assess the efficacy and safety of influenza vaccination in children and adults with asthma. SEARCH METHODS: We searched the Cochrane Airways Group trials register and reviewed reference lists of articles. The latest search was carried out in November 2012. SELECTION CRITERIA: We included randomised trials of influenza vaccination in children (over two years of age) and adults with asthma. We excluded studies involving people with chronic obstructive pulmonary disease. DATA COLLECTION AND ANALYSIS: Inclusion criteria and assessment of trial quality were applied by two review authors independently. Data extraction was done by two review authors independently. Study authors were contacted for missing information. MAIN RESULTS: Nine trials were included in the first published version of this review, and nine further trials have been included in four updates. The included studies cover a wide diversity of people, settings and types of influenza vaccination, and we pooled data from the studies that employed similar vaccines. PROTECTIVE EFFECTS OF INACTIVATED INFLUENZA VACCINE DURING THE INFLUENZA SEASON: A single parallel-group trial, involving 696 children, was able to assess the protective effects of influenza vaccination. There was no significant reduction in the number, duration or severity of influenza-related asthma exacerbations. There was no difference in the forced expiratory volume in one second (FEV) although children who had been vaccinated had better symptom scores during influenza-positive weeks. Two parallel-group trials in adults did not contribute data to these outcomes due to very low levels of confirmed influenza infection. ADVERSE EFFECTS OF INACTIVATED INFLUENZA VACCINE IN THE FIRST TWO WEEKS FOLLOWING VACCINATION: Two cross-over trials involving 1526 adults and 712 children (over three years old) with asthma compared inactivated trivalent split-virus influenza vaccine with a placebo injection. These trials excluded any clinically important increase in asthma exacerbations in the two weeks following influenza vaccination (risk difference 0.014; 95% confidence interval -0.010 to 0.037). However, there was significant heterogeneity between the findings of two trials involving 1104 adults in terms of asthma exacerbations in the first three days after vaccination with split-virus or surface-antigen inactivated vaccines. There was no significant difference in measures of healthcare utilisation, days off school/symptom-free days, mean lung function or medication usage.EFFECTS OF LIVE ATTENUATED (INTRANASAL) INFLUENZA VACCINATION: There were no significant differences found in exacerbations or measures of lung function following live attenuated cold recombinant vaccine versus placebo in two small studies on 17 adults and 48 children. There were no significant differences in asthma exacerbations found for the comparison live attenuated vaccine (intranasal) versus trivalent inactivated vaccine (intramuscular) in one study on 2229 children (over six years of age). AUTHORS' CONCLUSIONS: Uncertainty remains about the degree of protection that vaccination affords against asthma exacerbations that are related to influenza infection. Evidence from more recently published randomised trials of inactivated split-virus influenza vaccination indicates that there is no significant increase in asthma exacerbations immediately after vaccination in adults or children over three years of age. We were unable to address concerns regarding possible increased wheezing and hospital admissions in infants given live intranasal vaccination.
Large vertebrates affect fire regimes in several ways: by consuming plant matter that would otherwise accumulate as fuel; by controlling and varying the density of vegetation; and by engineering the soil and litter layer. These processes can regulate the frequency, intensity and extent of fire. The evidence for these effects is strongest in environments with intermediate rainfall, warm temperatures and graminoid-dominated ground vegetation. Probably, extinction of Quaternary megafauna triggered increased biomass burning in many such environments. Recent and continuing declines of large vertebrates are likely to be significant contributors to changes in fire regimes and vegetation that are currently being experienced in many parts of the world. To date, rewilding projects that aim to restore large herbivores have paid little attention to the value of large animals in moderating fire regimes. Rewilding potentially offers a powerful tool for managing the risks of wildfire and its impacts on natural and human values.
BACKGROUND: There is increasing evidence that the substantial global burden of disease for tuberculosis unfolds in concert with dimensions of common mental disorders. Person-centred care holds much promise to ameliorate these comorbidities in low-to-middle income countries (LMICs) and emerging economies. Towards this end, this paper aims to review 1) the nature and extent of tuberculosis and common mental disorder comorbidity and 2) person-centred tuberculosis care in low-to-middle income countries and emerging economies. MAIN TEXT: A scoping review of 100 articles was conducted of English-language studies published from 2000 to 2019 in peer-reviewed and grey literature, using established guidelines, for each of the study objectives. Four broad tuberculosis/mental disorder comorbidities were described in the literature, namely alcohol use and tuberculosis, depression and tuberculosis, anxiety and tuberculosis, and general mental health and tuberculosis. Rates of comorbidity varied widely across countries for depression, anxiety, alcohol use and general mental health. Alcohol use and tuberculosis were significantly related, especially in the context of poverty. The initial tuberculosis diagnostic episode had substantial socio-psychological effects on service users. While men tended to report higher rates of alcohol use and treatment default, women in general had worse mental health outcomes. Older age and a history of mental illness were also associated with pronounced tuberculosis and mental disorder comorbidity. Person-centred tuberculosis care interventions were almost absent, with only one study from Nepal identified. CONCLUSIONS: There is an emerging body of evidence describing the nature and extent of tuberculosis and mental disorders comorbidity in low-to-middle income countries. Despite the potential of person-centred interventions, evidence is limited. This review highlights a pronounced need to address psychosocial comorbidities with tuberculosis in LMICs, where models of person-centred tuberculosis care in routine care platforms may yield promising outcomes.
BACKGROUND: Pyrazinamide (PZA) is crucial for tuberculosis (TB) treatment, given its unique ability to eradicate persister bacilli. The worldwide burden of PZA resistance remains poorly described. METHODS: Systematic PubMed, Science Direct and Scopus searches for articles reporting phenotypic (liquid culture drug susceptibility testing or pyrazinamidase activity assays) and/or genotypic (polymerase chain reaction or DNA sequencing) PZA resistance. Global and regional summary estimates were obtained from random-effects meta-analysis, stratified by presence or risk of multidrug resistant TB (MDR-TB). Regional summary estimates were combined with regional WHO TB incidence estimates to determine the annual burden of PZA resistance. Information on single nucleotide polymorphisms (SNPs) in the pncA gene was aggregated to obtain a global summary. RESULTS: Pooled PZA resistance prevalence estimate was 16.2% (95% CI 11.2-21.2) among all TB cases, 41.3% (29.0-53.7) among patients at high MDR-TB risk, and 60.5% (52.3-68.6) among MDR-TB cases. The estimated global burden is 1.4 million new PZA resistant TB cases annually, about 270,000 in MDR-TB patients. Among 1,815 phenotypically resistant isolates, 608 unique SNPs occurred at 397 distinct positions throughout the pncA gene. INTERPRETATION: PZA resistance is ubiquitous, with an estimated one in six incident TB cases and more than half of all MDR-TB cases resistant to PZA globally. The diversity of SNPs across the pncA gene complicates the development of rapid molecular diagnostics. These findings caution against relying on PZA in current and future TB drug regimens, especially in MDR-TB patients.
Pulmonary hypertension (PH) is highly heterogeneous and despite treatment advances it remains a life‐shortening condition. There have been significant advances in imaging technologies, but despite evidence of their potential clinical utility, practice remains variable, dependent in part on imaging availability and expertise. This statement summarizes current and emerging imaging modalities and their potential role in the diagnosis and assessment of suspected PH. It also includes a review of commonly encountered clinical and radiological scenarios, and imaging and modeling‐based biomarkers. An expert panel was formed including clinicians, radiologists, imaging scientists, and computational modelers. Section editors generated a series of summary statements based on a review of the literature and professional experience and, following consensus review, a diagnostic algorithm and 55 statements were agreed. The diagnostic algorithm and summary statements emphasize the key role and added value of imaging in the diagnosis and assessment of PH and highlight areas requiring further research.
BACKGROUND: Respiratory symptoms such as cough and wheeze are associated with significant morbidity, including school absenteeism. METHODS: A respiratory questionnaire was sent to the parents of all 5727 children aged 7-9 years of age registered with 95 general practitioners in the Southampton area to determine (a) the prevalence of asthma, cough and wheeze, (b) the effects of respiratory symptoms on school absenteeism, and (c) the use of anti-asthma medication. RESULTS: A total of 4830 parents replied (response rate 86%). The 12 month prevalence of wheeze in the absence of cough was 5.5%, cough in the absence of wheeze was 10.0%, and 7.6% reported cough and wheeze; 15.2% of children had been diagnosed. Of the 4830 who replied, 12.7% were receiving bronchodilators, 0.6% xanthine derivatives, 1.7% sodium cromoglycate, and 4.1% inhaled corticosteroids. In all, 348 (7.2%) children had missed more than five days of schooling in the preceding year for respiratory symptoms, while 43 children (0.9%) had missed more than 20 days of schooling in the preceding year. Of the children who had missed more than five days of schooling, 43% reported cough and wheeze, 33% cough alone, and 16% wheeze alone in the preceding year. Compared with children who coughed, those who wheezed were significantly more likely to be diagnosed as asthmatic and to be receiving bronchodilators or inhaled corticosteroids. CONCLUSIONS: In this study, cough was the most frequently reported symptom amongst children missing more than five days of schooling per year.
The majority of Mycobacterium tuberculosis isolates resistant to isoniazid harbour a mutation in katG. Since these mutations cause a wide range of minimum inhibitory concentrations (MICs), largely below the serum level reached with higher dosing (15 mg/L upon 15-20 mg/kg), the drug might still remain partly active in presence of a katG mutation. We therefore investigated which genetic mutations predict the level of phenotypic isoniazid resistance in clinical M. tuberculosis isolates. To this end, the association between known and unknown isoniazid resistance-conferring mutations in whole genome sequences, and the isoniazid MICs of 176 isolates was examined. We found mostly moderate-level resistance characterized by a mode of 6.4 mg/L for the very common katG Ser315Thr mutation, and always very high MICs (≥19.2 mg/L) for the combination of katG Ser315Thr and inhA c-15t. Contrary to common belief, isolates harbouring inhA c-15t alone, partly also showed moderate-level resistance, particularly when combined with inhA Ser94Ala. No overt association between low-confidence or unknown mutations, except in katG, and isoniazid resistance (level) was found. Except for the rare katG deletion, line probe assay is thus not sufficiently accurate to predict the level of isoniazid resistance for a single mutation in katG or inhA.
Introduction: Climate change may worsen existing indoor air problems and create new problems by altering outdoor conditions that affect indoor conditions. Since climate change is due to both natural variability and human-induced contributions, public health professionals through their expertise in health promotion and behavior change can play a vital role in promoting lifestyle choices that will decrease greenhouse gas emissions. This study, therefore, aims at presenting the health effects of indoor air pollutants from biomass use. Methods: A cross sectional study involving 1,170 consenting women was conducted in Masaiti and Ndola districts of Zambia. Data collection tools included a structured questionnaire; foobot (indoor air quality monitoring device) and spirometer (lung function test device). Data was analyzed using SPSS version 16 and analyses were done at Univariate, bivariate and multivariate level at 5% statistical significant level. Results: Population using biomass as cooking fuel was 69.2%. Indoor particulate (PM2.5) overall median (Q1, Q2) distribution during cooking period was 501(411, 686) ?g/m3 and daily average was 393(303,578) ?g/m3 while VOC daily average was 343(320, 363) ppb. The proportion of women with respiratory symptoms and impaired lung functions was higher in households with high levels of indoor pollutants. There was a statistically significant association between mean indoor particulate concentration levels and the number of maternal respiratory symptoms. There was a significant association between indoor VOC and forced vital capacity (p=0.011). Conclusion: The results contribute to the growing evidence regarding the effect of biomass use on indoor air quality and consequent adverse respiratory health outcomes.
Sarcoidosis is a multisystem granulomatous disorder invariably affecting the lungs. It is a disease with noteworthy variations in clinical manifestation and disease outcome and has been described as an "immune paradox" with peripheral anergy despite exaggerated inflammation at disease sites. Despite extensive research, sarcoidosis remains a disease with undetermined aetiology. Current evidence supports the notion that the immune response in sarcoidosis is driven by a putative antigen in a genetically susceptible individual. Unfortunately, there currently exists no reliable biomarker to delineate the disease severity and prognosis. As such, the diagnosis of sarcoidosis remains a vexing clinical challenge. In this review, we outline the immunological features of sarcoidosis, discuss the evidence for and against various candidate etiological agents (infective and noninfective), describe the exhaled breath condensate, a novel method of identifying immunological biomarkers, and suggest other possible immunological biomarkers to better characterise the immunopathogenesis of sarcoidosis.
Treatment failure is a serious problem facing some national tuberculosis (TB) control programmes. Irregularity of treatment is a factor that can lead to treatment failure. A case-control study was carried out in TB centres in Egypt during April 2001-December 2002 aimed at investigating the predictors of treatment failure. We interviewed 119 people with treatment failure and an equal number of cured cases (controls) and their families regarding sociodemographic characteristics, information about TB, information about drugs, treatment compliance, family support and patient-family interaction. Significant risk factors for treatment failure were non-compliance to treatment, deficient health education to the patient, poor patient knowledge regarding the disease and diabetes mellitus as co-morbid condition.
BACKGROUND: Role confusion is hampering the development of nurses' capacity for health promotion and prevention. Addressing this requires discussion to reach agreement among nurses, managers, co-workers, professional associations, academics and organisations about the nursing activities in this field. Forming a sound basis for this discussion is essential. AIMS AND OBJECTIVES: To provide a description of the state of nursing health promotion and prevention practice expressed in terms of activities classifiable under the Ottawa Charter and to reveal the misalignments between this portrayal and the ideal one proposed by the Ottawa Charter. METHODS: A critical interpretive synthesis was conducted between December 2018 and May 2019. The PubMed, CINAHL, Scopus, PsychINFO, Web of Science and Dialnet databases were searched. Sixty-two papers were identified. The relevant data were extracted using a pro-forma, and the reviewers performed an integrative synthesis. The ENTREQ reporting guidelines were used for this review. RESULTS: Thirty synthetic constructs were developed into the following synthesising arguments: (a) addressing individuals' lifestyles versus developing their personal skills; (b) focusing on environmental hazards versus creating supportive environments; (c) action on families versus strengthening communities; (d) promoting community partnerships versus strengthening community action; and (e) influencing policies versus building healthy public policy. CONCLUSIONS: There are notable misalignments between nurses' current practice in health promotion and prevention and the Ottawa Charter's actions and strategies. This may be explained by the nurses' lack of understanding of health promotion and prevention and political will, research methodological flaws, the predominance of a biomedical perspective within organisations and the lack of organisational prioritisation for health promotion and prevention.
Background. Since the end of December 2019, novel coronavirus- (SARS-CoV-2-) infected pneumonia (COVID-19) has spread rapidly in China. The study was designed to describe the clinical characteristics of COVID-19 patients with and without diabetes in Wuhan. Methods. 199 COVID-19 patients were admitted to Wuhan Red Cross Hospital in China from January 24th to March 15th. The cases were divided into the diabetic and nondiabetic groups according to the history of taking antidiabetic drugs or by plasma fasting blood glucose level at admission, and the differences between the groups were compared. A multivariable analysis of independent risk factors for in-hospital death was performed. Results. Among 199 COVID-19 patients, 76 were diabetic and 123 were nondiabetic. Compared with nondiabetics, patients with diabetes were older and had high levels of fasting plasma glucose (FPG), D-dimer, white blood cells, blood urea nitrogen (BUN), and total bilirubin (TBIL) and lower levels of lymphocytes, albumin and oxygen saturation (SaO2), and higher mortality ( <a:math xmlns:a="http://www.w3.org/1998/Math/MathML" id="M1"> <a:mi>P</a:mi> <a:mo><</a:mo> <a:mn>0.05</a:mn> </a:math> ). The two groups showed no difference in clinical symptoms. Diabetes (odds ratio (OR): 10.816, 95% CI (confidence interval): 1.895-61.741, <c:math xmlns:c="http://www.w3.org/1998/Math/MathML" id="M2"> <c:mi>P</c:mi> <c:mo>=</c:mo> <c:mn>0.007</c:mn> </c:math> ), higher level of D-dimer at admission (OR: 1.094, 95% CI: 1.017-1.178, <e:math xmlns:e="http://www.w3.org/1998/Math/MathML" id="M3"> <e:mi>P</e:mi> <e:mo>=</e:mo> <e:mn>0.016</e:mn> </e:math> ), and a <g:math xmlns:g="http://www.w3.org/1998/Math/MathML" id="M4"> <g:mtext>lymphocyte</g:mtext> <g:mtext> </g:mtext> <g:mtext>count</g:mtext> <g:mo><</g:mo> <g:mn>0.6</g:mn> <g:mo>×</g:mo> <g:msup> <g:mrow> <g:mn>10</g:mn> </g:mrow> <g:mrow> <g:mn>9</g:mn> </g:mrow> </g:msup> <g:mo>/</g:mo> <g:mtext>L</g:mtext> </g:math> at admission (OR: 7.609, 95% CI: 1.087-32.049, <i:math xmlns:i="http://www.w3.org/1998/Math/MathML" id="M5"> <i:mi>P</i:mi> <i:mo>=</i:mo> <i:mn>0.006</i:mn> </i:math> ) were associated with increasing odds of death. Antidiabetic drugs were associated with decreasing odds of death. Treatment with low molecular weight heparin was not related to odds of death. Conclusion. The mortality rate of COVID-19 patients with diabetes was significantly higher than those without diabetes. Diabetes, higher level of D-dimer, and a <k:math xmlns:k="http://www.w3.org/1998/Math/MathML" id="M6"> <k:mtext>lymphocyte</k:mtext> <k:mtext> </k:mtext> <k:mtext>count</k:mtext> <k:mo><</k:mo> <k:mn>0.6</k:mn> <k:mo>×</k:mo> <k:msup> <k:mrow> <k:mn>10</k:mn> </k:mrow> <k:mrow> <k:mn>9</k:mn> </k:mrow> </k:msup> <k:mo>/</k:mo> <k:mtext>L</k:mtext> </k:math> at admission were the risk factors associated with in-hospital death.
PURPOSE: The aim of the study was to assess QoL and identify and analyse its determinants in women with endometriosis. METHODS: The study was performed in 2019 in health centres in Lublin (Poland) on 309 women with diagnosed endometriosis. In order to verify which factors affect QoL of the study participants, regression for qualitative variables (CATREG) was used. The applied research instruments included the WHOQOL-BREF quality of life questionnaire, the Acceptance of Illness Scale (AIS), the Laitinen Pain Scale, and a general questionnaire. RESULTS: The overall QoL score of the respondents was 3.30, whereas their overall perceived health score was 2.37. The highest QoL scores were found for the psychological domain 13.33, whereas the lowest QoL were found for the physical domain 11.52. Women with endometriosis have a moderate level of illness acceptance (24.64) and experience daily pain of moderate intensity (5.83). CONCLUSION: Women with endometriosis rate their overall QoL higher than their overall perceived health. Perceived QoL in women with endometriosis is most commonly associated with their acceptance of illness, BMI, negative impact of symptoms on the relationship with the partner, and dyspareunia. To improve these women's lives, care should also respond to the social, emotional, and sexual issues resulting from the illness. Such interventions will contribute to improved comfort and QoL among these women.
Leptin is a product of the obese (OB) gene secreted by adipocytes in proportion to fat mass. It decreases food intake and increases energy expenditure by affecting the balance between orexigenic and anorexigenic hypothalamic pathways. Low leptin levels are responsible for the compensatory increase in appetite and body weight and decreased energy expenditure (EE) following caloric deprivation. The anorexia-cachexia syndrome is a complication of many chronic conditions including cancer, chronic obstructive pulmonary disease, congestive heart failure, chronic kidney disease, and aging, where the decrease in body weight and food intake is not followed by a compensatory increase in appetite or decreased EE. Crosstalk between leptin and inflammatory signaling known to be activated in these conditions may be responsible for this paradox. This manuscript will review the evidence and potential mechanisms mediating changes in the leptin pathway in the setting of anorexia and cachexia associated with chronic diseases.
