RESUMO

The aim of this study was to measure the prevalence of FCR among a sample of French lymphoma survivors and to determine factors associated with clinical levels of FCR. The study was conducted with two cross-sectional measures: sociodemographic and anxiety, depression as well as health-related quality of life (HRQoL) scores were measured at the baseline of the post-cancer period and FCR was evaluated during the first 3 years of survivorship. The prevalence of clinical levels of FCR (≥13) was evaluated by the Fear of Cancer Recurrence Inventory - Short Form (FCRI-SF) among non- and Hodgkin lymphoma survivors undergoing prior first-line chemotherapy. Among 108 lymphoma survivors with an average follow-up of 1.6 years (range 0.3-3.0 years), clinical levels of FCR (≥13) were observed for 44.4% (n = 48). Multivariate analysis indicated that baseline anxiety and low quality of life were related to clinically significant FCR levels.

RESUMO

OBJECTIVES: Assessing the quality of the clinical management of prostate cancer in the Midi-Pyrenean region in 2011. METHODS: The study population was randomly selected among new cases of prostate cancer presented in Multidisciplinary Team Meeting (MTM) in 2011. The indicators defined with the professionals have evaluated the quality of the diagnostic care, when treatment started and at the time of the MTM. RESULTS: Six hundred and thirty-three new patients were included (median age at diagnosis=69years, min: 48; max: 93). In diagnostic period, 92% of patients had a prostate biopsy. Performing a pelvic MRI, an abdomino-pelvic CT and bone scintigraphy concerned respectively 53%, 55% and 61% of intermediate or high-risk patients. The Gleason score, surgical margins and pathological stage were included in over 98% patient records treated by radical prostatectomy. A PSA assay in 3months after prostatectomy was found in 59% of surgical patients. The MTM was performed before treatment to 83% of patients. About three-quarters of surgical patients with stage pT≥3 or pN1 or with no healthy margins were discussed in MTM after surgery. CONCLUSION: Most of the studied indicators reach a high level. However, the lower level of realization of complementary examinations may question about their real place, accessibility and traceability. LEVEL OF EVIDENCE: 4.

RESUMO

BACKGROUND: Healthcare providers-related disparities in adherence to the treatment plan among lymphoma patients are found even in a universal healthcare system, but the mechanism remains unclear. We investigated the association between the type of care center and the relative dose intensity and determined whether it persists after adjustment for patients' recruitment differences. METHODS: Prospective observational cohort study of 294 patients treated with standard protocols for diffuse large B-cell lymphoma (DLBCL) in teaching or community public hospitals or in private centers in the French Midi-Pyrénées region from 2006-2013. To test our assumptions, we used multinomial and mixed-effect logistic models progressively adjusted for patients' biomedical characteristics, socio-spatial characteristics and treatment-related toxicity events. RESULTS: Patients treated using standard protocols in the teaching hospital had more advanced stage and poorer initial prognosis without limitation regarding the distance from the residence to the care center. Patients' recruitment profile across the different types of care center failed to explain the difference in relative dose intensity. Low relative dose intensity was less often observed in teaching hospital than elsewhere. CONCLUSION: We showed that even in a universal healthcare system, disparities in the management of DLBCL patients' do exist according to the types of care center. A main issue may be to find and diffuse the reasons of this benefit in cancer management in the teaching hospital to the other centers.

RESUMO

In the field of health, evidence-based medicine and associated methods like randomised controlled trials (RCTs) have become widely used. RCT has become the gold standard for evaluating causal links between interventions and health results. Originating in pharmacology, this method has been progressively expanded to medical devices, non-pharmacological individual interventions, as well as collective public health interventions. Its use in these domains has led to the formulation of several limits, and it has been called into question as an undisputed gold standard. Some of those limits (e.g. confounding biases and external validity) are common to these four different domains, while others are more specific. This paper describes the different limits, as well as several research avenues. Some are methodological reflections aiming at adapting RCT to the complexity of the tested interventions, and at overcoming some of its limits. Others are alternative methods. The objective is not to remove RCT from the range of evaluation methodologies, but to resituate it within this range. The aim is to encourage choosing between different methods according to the features and the level of the intervention to evaluate, thereby calling for methodological pluralism.

RESUMO

BACKGROUND: Substance use has increased worldwide. Based on these data, we may think that substance use has also increased during pregnancy, but epidemiological data are scarce in this population. The potential consequences of tobacco, cocaine or cannabis use during pregnancy are a major public health concern. The combined use of different substances during pregnancy may have serious consequences on the pregnancy and on child development. METHODS: In this paper, we will describe the potential consequences for the newborn, child and adolescent after being exposed to tobacco, cannabis and cocaine in utero. For this purpose, we will review all retrospective and prospective studies (in English and French) referenced in PubMed reporting on the somatic or psychiatric consequences of alcohol, tobacco and drug consumption by pregnant women on newborn and children. Consumption during pregnancy was assessed in these studies using simple questionnaires, biomarkers analysis or both. RESULTS: Generally speaking, these pregnancies are at high risk for both the mother and the foetus: for example, an increased risk of miscarriage or of reduced length of gestation, an increased risk of uterine apoplexy and placenta praevia, more premature births and/or hypotrophy were reported. The occurrence of a newborn's withdrawal syndrome may be misdiagnosed. Many consequences on child development may be observed such as growth disorders, learning or motor disorders, language disorders, cognitive disorders (attention, memory, executive functions), attention deficit disorders with impulsivity or with hyperactivity (ADHD), and memory disorders. The prevalence of depressive or anxiety disorders may also be increased in these children. The risk of addictive disorders or schizophrenia in children exposed in utero to illicit drugs or tobacco is still unknown. The combined use of different substances increases, consequently it is difficult to disentangle the consequences on child development of each of the drugs used during pregnancy owing to potential interactions between these drugs. The consequences on child development will also depend on the dose and on the time of drug use during pregnancy. DISCUSSION: The National Institute of Drug Abuse reported that 75% of the infants exposed in utero to one or more substances will present medical problems during childhood, as compared to only 27% of the non-exposed infants. However, the medical consequences are still a matter of controversies. Methodological biases, such as the use of different rating scales among studies, and the heterogeneity of the populations included are main limitations. Further studies are needed using larger cohorts and longer follow-up periods.

RESUMO

The population hospitalised in psychiatry seems more exposed to traumatic events than the French general population, with particularly more sexual aggressions. The aim of this study is to describe the population hospitalised in psychiatry and more precisely the traumatic history of these patients, their comorbidities (mental diseases and addictions), and socio economical level. This descriptive, cross sectional and retrospective study took place in the Crisis Center in the University Hospital in Martinique (French West Indies), from February to July 2013. A socio-demographic information, the Mini International Neuropsychiatric Interview 5.0, the Trauma History Questionnaire and the Impact Events Scale-Revised were realised with 49 of the 143 patients admitted during this period (34.3%). In this population, we found a mean of 6.5 (standart-deviation=4.2) different types of traumatic event, with 38.8% patients reporting a natural disaster, and 38.8% declaring at least one sexual aggression. In the 25 patients suffering from post-traumatic stress disorder, 66.7% underwent a sexual aggression, significatively during childhood (before 10 years old, P=0.01), and during adolescence (between 10 to 18 years old, P=0.01). These results underline the importance of a systematic screening of the traumatic profile: the characteristics of the traumatic events and its clinical impact.

RESUMO

Prostate cancer incidence has tripled in Luxembourg as in many other western countries. From 1982 to 2006, new cases increased from 80 to 309 per year, while the incidence (world stand.pop.) rose from 29.5 to 85 per 100 000 men. Since 1991 prostate cancer is the most frequent male cancer in Luxembourg, exceeding colo-rectal, lung and stomach cancer. Prostate cancer deaths have diminished from 64 in 1982 to 45 in 2006. This represents less than 10% of male cancer related deaths; it represents the third most frequent cancer death, behind lung and colo-rectal cancers. Annual mortality rate has decreased from 29 to 10 per 100 000 men during the same period, this difference between incidence and mortality is explained on the one hand by the widespread use of PSA since the 1990's and on the other hand by a better local control as well as a multidisciplinary approach of advanced disease. The increase of the incidence is particularly important in the 60 to 70 age group, while for men older than 70, the peak incidence was reached in 2002. A lowering of the age at diagnosis is confirmed by the 5-year age group analysis. The hospital cohort consists of 628 patients from the urological department of the Centre Hospitalier de Luxembourg diagnosed with prostate cancer between 1st January 1982 and 31st December 2006; follow-up ended 31st December 2011. During this period, age at diagnosis decreased from 71.5 to 68.9 years whereas the proportion of localized clinical stages increased from 44 to 70%. Median PSA dropped from 14.5 to 9 ng/ml. Furthermore the analysis of cancer specific mortality confirms the negative effects of an advanced clinical stage (10-year survival: 90% for localized disease, 60% for advanced disease) or a high PSA level at diagnosis (10-year survival: 97% if PSA < 4 ng/nl, 94% if 4 < PSA < 10, and 72% if PSA > 10 ng/ml), as well as a poor differentiation (60% 10-year survival compared to 90% for differentiated tumors). Kaplan-Meier curves show that long term surveillance is necessary as even tumors with a good initial prognosis may relapse after 10-12 years.

RESUMO

Biocides are added to biodiesels to inhibit and remove microbial growth. The effects of 5-chloro-2-methyl-4-isothiazolin-3-one (CMIT), a candidate biodiesel biocide, were studied using freshly isolated rat alveolar macrophages (AM) and NR8383 cell line. CMIT markedly inhibited phagocytic oxidative burst as measured by zymosan-induced chemiluminescence, and cellular cytokine secretion as measured by zymosan-induced TNF-α secretion. The 50% inhibition concentration (LC(50)) for CMIT was 0.002-0.004 mM for both cellular functions. AM exposed to CMIT for as little as 2 min showed markedly inhibited functions that persisted for at least 5 h. Sodium metabisulfite was able to partially neutralize the inhibitory activity of CMIT. Cysteine and glutathione, when present at a molar ratio of 2-1 or higher against CMIT, were effective neutralizers, while serine, histidine, alanine, and albumin were without effect. When the AM testing system was used to compare the toxicity of CMIT against three other candidate biodiesel biocides, methylene dithiocyanate (MDC) was found to be of comparable toxicity to CMIT, 2-methyl-4-isothiazolin-3-one (MIT) was much less toxic, and dimethyl acetylenedicarboxylate (DMAD) was non-toxic. Because AM is among the first cell-type exposed to inhaled biodiesel aerosols, the result suggested that CMIT present in biodiesel may produce respiratory effects, and further investigations including animal studies are warranted.

RESUMO

All around the world, the potential consequences of the increasing use of psychoactive substances during pregnancy are a major public health concern. It is estimated that 20 to 30% of pregnant women use tobacco, 15% use alcohol, 3 to 10% use cannabis and 0.5 to 3% use cocaine. The estimation of tobacco consumption during pregnancy is better known as compared with alcohol and substance use prevalence during pregnancy, which remains under estimated or unknown. For example, in France, the prevalence of cannabis and cocaine use during pregnancy is unknown. In general, the prevalence of drug or alcohol use during pregnancy is estimated by extrapolating data from epidemiological studies conducted in the general population (in France or in other countries). However, drug or alcohol use in the general population may dramatically vary from one country to another. Even if some studies have reported the prevalence of alcohol or substance use in different countries around the world, most of them were based on the mother's interview. In most cases, the mother did not report exactly the amount of drugs or alcohol used. Further studies measuring alcohol or substance use in the mother's blood, hair or in the newborn's meconium are needed. In addition, different methodologies have been used in the literature (different types of interview, with or without biological measurements; different subjects included (in- or out-pregnant women, psychiatric comorbidities or not, different economic status, etc). Despite these methodological biases, the prevalence of drug or alcohol use increases in pregnant women, and in most cases, several drugs are associated. Most of the studies have used structured or semi-structured interviews such as the addiction severity index (ASI) or the alcohol use disorders identification test (AUDIT) to assess alcohol or drug consumption. In addition, the identification of risk factors for substance or alcohol use during pregnancy would allow the early detection of these high-risk pregnancies. Environmental factors such as low economic status or marital status may play an important role. Personality disorders may also contribute to substance or alcohol use during pregnancy. In fact, in most studies the quality of the obstetrical survey is lower in pregnant women using drugs or alcohol but it remains difficult to describe a specific at-risk profile in these pregnant women. Consumption of alcohol or of one or more psychoactive substances during pregnancy may have serious consequences on the pregnancy and on the child's development. Fetal alcoholism syndrome is the main etiology of mental retardation in France. We need to improve our knowledge of alcohol and substance use during pregnancy in order to target information for prevention campaigns and to implement specific mother and child medical care in high-risk populations.

RESUMO

BACKGROUND: Studies have shown clinical practices variation between centers in colorectal cancer (CRC) management. After the implementation of national cancer plans, we tested for differences in center and patients' socioeconomic position (SEP)-related variation in CRC guidelines. METHODS: All patients aged 18 years and over, cared for a first CRC in 2010 in Southwest of France. We used mixed effect model to test for center-related heterogeneity (CRH) in recommendation, from the oldest to the more recent: (1) at least 12 lymph nodes analysed for stage II, (2) the prescription of adjuvant chemotherapy stage III and (3) the assessment of CRC molecular phenotype regarding KRAS status for stage IV. Patients' SEP was approached by an ecological social deprivation index. RESULTS: We found: higher adherence for the oldest than for the most recent recommendations; no CRH in recommendation No. 2 but lower adherence in academic centers; a CRH for recommendations No. 1 and 3; no SEP-related differences in clinical practices. CONCLUSION: Results showed that older recommendations have higher adherence but did not support increasing influence of centers characteristics and CRH as recommendations are more recent.

RESUMO

In 2003, the PHDG (Prevalence of Hypertension among Disadvantaged Guadeloupeans) study highlighted poor management of hypertension in an unemployed French Caribbean population. New processes of health-care coordination and a pay-for-performance system have since been developed. We aimed to assess changes in hypertension characteristics in disadvantaged French Caribbean populations in the last 10 years. Using PHDG 2003 data, in 2014 we undertook a cross-sectional study with identical methods. The source population comprised all Guadeloupeans having undergone periodic heath checks offered by the Social Security insurance at these dates. Only universal health coverage beneficiaries (i.e. in situations of poverty) aged 18-64 were included (2014 in 2014, 1868 in 2003). Hypertension was defined by antihypertensive treatment or a mean of two blood pressure measures ⩾140/90 mm Hg. The 2003 and 2014 data were age adjusted; comparative morbidity factors (CMF) and 95% confidence intervals were calculated to assess changes over time. Hypertension prevalence decreased from 38.3 to 34.5% (CMF 95% CI: 0.83-0.97). The increase in hypertension awareness was greater for women (from 48.3 to 55.3%, CMF 95% CI: 1.00-1.31) than for men (from 28 to 31.1%, NS). Among hypertensive individuals aware of their condition, proportions of those treated increased for women (from 83.1 to 88.3%, NS) but decreased for men (from 80.2 to 75.8%, NS). Controlled hypertension among treated patients increased in women (from 35.2 to 49.2%, CMF 95% CI: 1.07-1.82) and men (from 12.9 to 30.1%, CMF 95% CI: 1.30-4.21). In conclusion, in these poor French Caribbean populations with theoretically adequate access to care, hypertension control remained far below national goals. Neither awareness nor treatment had improved in men.

RESUMO

Short-term reactions of young turkeys to changes in the physical characteristics of their feed sometimes give rise to problems of adaptation in the field. Specific feeders were designed for this study to automatically count the number of pecks given at feed by 4-wk-old male turkeys during 95-min sessions. The lighting program was intermittent (0140L:0100D). In experiment 1, 4 series of 12 birds were tested 4 times/day from 28 to 31 d of age. Four control turkeys were consistently tested with 1 feed, and 8 experimental turkeys ate 1 of 32 commercial feeds (30 as pellets and 2 as crumbs) with a distinct feed for each test (16 replicates/experimental feed). Feed intake, total number of pecks, and pecking efficiency (mg/peck) were recorded for each test and normalized for each turkey. The effects of series, day, and test were not significant for controls. The number of pecks and pecking efficiency differed among feeds (P < 0.001) but not feed intake. Hierarchical Cluster Analysis for these variables distinguished 3 groups of feed: group 3 (6 crumb and small pellets) resulted in high pecking and low efficiency. However, group 1 (10 feeds) were pecked at less but more efficiently than group 2 (16 feeds) for similar feed intake, although the average sizes of the pellets were similar (6.23 and 6.16 mm, respectively), as were the average bulk density, hardness, resistance to abrasion, and color characteristics of the pellets for both groups. Two feeds of each of these 2 groups were compared in a second experiment for 12 turkeys receiving the 4 feeds successively each day over 4 d in varying order. The turkeys consistently pecked the feeds of group 1 less and less efficiently compared with group 2. The automated measurement of pecking, combined with a more detailed image analysis of feed particles, might enhance the evaluation of the effects of feed technology on the behavior of turkeys and thus become a useful tool for the feed industry.

RESUMO

BACKGROUND: Prostate Specific Antigen (PSA) is widely used for the detection and monitoring of prostate cancer (CAP) but PSA is elevated in many patients with benign prostatic hyperplasia (BPH). The measurement of free PSA may improve the discrimination between CAP and BPH. MATERIAL AND METHODS: Free PSA (F-PSA) and total PSA (T-PSA) were measured using kits based on the Enzymun-Test principle. The patient population was composed of 38 untreated CAP patients, 76 BPH patients and 29 prostatitis patients. RESULTS: At cut-off levels of 0.15 for the F-PSA/T-PSA ratio and 10 ng/ml for T-PSA the specificity and sensitivity for detecting CAP were respectively 87% and 84% for F-PSA/T-PSA ratio and 80% and 63% for T-PSA. CONCLUSION: The F-PSA/T-PSA ratio is more powerful at discriminating between CAP and BPH than T-PSA alone and may contribute to a reduction in unnecessary invasive techniques.

RESUMO

Musty, earthy odors are highly detrimental to the aromatic quality of wines. A characteristic aroma of freshly tilled earth, damp cellar was studied in some red and white wines of different origins. The extraction and purification of the wines marked by this odor have shown after analysis by gas chromatography-olfactometry a unique strong odorous zone having the same odor as the one perceived at tasting. The compound responsible for this odorous zone was identified by gas chromatography-mass spectrometry as geosmin (trans-1,10-dimethyl-trans-9-decalol), which possesses a distinctive earthy odor. Geosmin may be present in wines at levels higher than the racemic geosmin olfactory perception threshold, thus suggesting its contribution to their off-aroma. Moreover, the presence of this compound in juice taken from freshly crushed grapes suggests that microorganisms that develop on the grapes may contribute to the presence of this compound in wines.

RESUMO

PAN is one of a class of common air pollutants formed by the action of sunlight on volatile organic compounds and nitrogen oxides. No toxicokinetic studies have been found in the available literature. The acute toxicity of PAN is less than that of ozone, similar to NO2 and higher than SO2. The LC30, in mice and rats were 718-743 mg/m3 (for 2 h) and 470 mg/m3 (for 4 h), respectively. Following acute exposure, severe lung lesions and, at the higher levels, damage to the epithelium of upper parts of the respiratory tract were found in animals. It seems that concentrations of 1.19-1.49 mg/m3 lie not far from the threshold required for pulmonary function effects in sensitive individuals. However, these PAN concentrations are well above the maximum ambient concentrations usually experienced within the USA and Canada (0.003-0.078 mg/m3). It appears unlikely that present ambient PAN concentrations would affect pulmonary functions responses to ambient ozone. In human, the lowest level causing eye irritations was 0.64 mg/m3 for 2 h. Concentrations of 0.99 and 4.95 mg/m3 were identified as no-observed-effect level (NOEL) and no-observed-adverse-effect level (NOAEL) for pathological and histological changes in the respiratory system (nasal passages) of rats during subchronic exposures to PAN, but were not considered to be relevant to derivation of a RfC for chronic inhalation exposure. PAN is a weak point mutagen or clastogen. The data are not sufficient to evaluate its carcinogenicity. No study was found which could be used for the derivation of a RfC for acute or chronic inhalation exposure to PAN.

RESUMO

We reviewed the trends in prostate cancer incidence and mortality in Luxembourg between 1983 and 1995 to discuss the importance of total and free PSA in early detection. The study was performed on all the new cases recorded by the National Cancer Registry (Registre Morphologique des Tumeurs). Total and free PSA were measured with the automated Immulite System (DPC, Los Angeles) using a chemoluminescent immunometric assay. The performance of free-to-total serum PSA was analysed by a hospital based study of 113 patients (55 PC, 58 BPH). The age standardized incidence rate increased from 29.3/100,000 in 1983 to 71.5/100,000 in 1995. Mortality rates only changed slightly. The widespread use of PSA testing from 1988 on is probably the main cause of this incidental increase; however no major changes in the age-specific-incidence have been found suggesting the absence of a systematic screening policy by the PSA. The superiority of free-to-total serum PSA ratio in discriminating between cancer and benign condition was confirmed. Early health-conscious man over 50 should be proposed prostate cancer screening by digital rectal examination and PSA. However a systematic screening policy cannot been recommended since a benefit in survival after early treatment has not yet been proven.

RESUMO

Spontaneous regression of lung-metastases in kidney cancer (a case report) A case is reported of a 56-year old woman with renal cell carcinoma operated and treated adjuvantly for a year with Interferon alpha. Ten months thereafter the patient had histologically proven a large pulmonary metastatic disease that regressed spontaneously. Duration of the spontaneous remission was 8 months.

RESUMO

The authors report the importance of not only all over the world but also in Portugal and, particularly, in Dona Estefânia Hospital. Some considerations are made about the usefulness of molecular biology methods in prenatal diagnosis. With this tool can also be do the origins and migrations of populations, which contributes to the knowledge of aspects of our history. Finally, they present consensual attitudes which should adopt regarding these chronic diseases, with special emphasis to the prophylactic aspects.

RESUMO

A case of cystic fibrosis presented in the neonatal period with respiratory symptomatology associated with early pancreatic insufficiency is reported. The CFTR gene molecular analysis was found to be a compound heterozygotes for delta F508 and G542X. The rarity of this mode of presentation and the inclusion of this entity in the differential diagnosis for neonatal respiratory distress syndrome is emphasised. The pathogenesis and some therapeutic aspects carried out in our patient, which might have improved the life expectancy of patients with this disease, are discussed.
