Objectives: The aim of this study is to provide relevant and accurate information on prevalence and treatment patterns of anaemia in Belgian cancer patients. Methods The Anaemia Day 2008 survey was a single visit, multi-centre, non-interventional study in adult cancer patients under systemic therapy (chemotherapy, hormonal, immunological and/or targeted therapy) and/or radiotherapy. Efforts were made to enrol the maximum number of patients seen in each centre that day. Patients signed an informed consent and relevant data were collected from their files, i.e. disease and disease stage, cancer therapy and anti-anaemic treatment, including transfusions and the use of erythropoietin stimulating agents (ESA). A blood count of each included patient was performed. Haemoglobin (Hb) values (grams per decilitre) were classified into four categories to assess the severity of anaemia, as defined byWHO: no anaemia: Hb≥12 g/dL; mild 10≤Hb≤11.9 g/dL; moderate 8≤Hb≤9.9 g/dL; severe Hb< 8 g/dL. Univariate and multivariate analyses were carried out with anaemia as the dependent variable. Results A total of 1,403 eligible patients aged 63±13 years (mean age±SD) were enrolled in 106 oncology or haematology centres. The mean Hb level (±SD) was 11.6 g/dL (±1.8 g/dL) and the prevalence of anaemia (Hb<12 g/dL) was 55.7% (95% CI, 53.1–58.3%), respectively, 35.9% mild, 17.8% moderate and 2.1% severe anaemia. Anaemia was more frequent in females than in males, and in patients with haematological malignancies (73.4%) than in those with solid tumours (51.4%; p<0.001). Anaemia prevalence was higher in hospitalised patients (75.5%) compared to those seen in one-day-clinic (54.3%) or in consultation (33.9%; p<0.001), and in patients treated with chemotherapy (61.3%) compared to those receiving radiotherapy (34.4%) or hormonal therapy (19.5%; p<0.001). There was a clear correlation between severity of anaemia and WHO performance status (p< 0.001). Among anaemic patients, 53.1% received no treatment (mean Hb 10.8±0.9 g/dL). Among the anaemic patients who received therapy for their anaemia (mean Hb 9.7±1.1 g/dL), the most frequent treatments were RBC transfusions (42%), ESA (34.6%), transfusions+ESA (12%), ESA+iron (7.9%) and iron alone (3.5%). Comparison to the ECAS survey shows that there has been no major change in attitude towards anaemia management in the last decade. Conclusion This survey shows that cancer-related anaemia is still frequently observed in cancer patients. Even if in our study ESA were used more frequently than about 10 years ago, still a large amount of anaemic patients who could be treated for anaemia according to EORTC guidelines, were not.

AIMS: To estimate viral seroprevalences for HCV, HBV and HIV among belgian intravenous (IVDU) and non intravenous (non-IVDU) drug users; to assess risk factors for HCV infection in IVDU; to assess feasibility of chronic hepatitis C follow-up in this population. DESIGN: Cross-sectional study. Demographic and behavioural characteristics were obtained by a standardized questionnaire. Serum samples were tested for HCV, HBV and HIV. SUBJECTS AND SETTING: 329 patients (244 IVDU and 85 non-IVDU) attending ten general practitioners in 1995. RESULTS: HCV seroprevalence was 78.3%; it was 35.7% for HBV and 0.9% for HIV in IVDU, vs 2.4%, 8.3% and 0%, respectively, in non-IVDU. In logistic regression analysis, independent risk factors for HCV infection were: 1/sharing of syringes and/or of "cottons" used as filters (adjusted prevalence odds ratio [POR] = 31.7; 95% confidence interval [CI] = 9.8-102.5), 2/duration of injecting upper than one month (adjusted POR = 8.6; CI = 3.0-24.7) and 3/age (adjusted POR = 1.2 by year of difference; CI = 1.0-1.3). A biochemical follow-up was obtained in 70% of HCV seropositive users; 79.5% of them had chronic hepatitis C (mean value of ALT = 3.5 times upper normal value, range 1.1-23.0). Among these, 24.7% went through liver biopsy during the three years follow-up period of the study. CONCLUSIONS: HCV seroprevalence is very high among belgian IVDU. Prevention strategies have to focus on neophytes injectors. They must be urgently revisited for what concern needles/syringes exchange programs: "cottons" must be included. Follow-up and treatment of chronic hepatitis C seem to be poorly effective among drug users. [less ▲]

OBJECTIVE: The aim of this study was to determine the prevalence of human papillomavirus (HPV) in 80 tumor-free tonsils from healthy children and adults using a sensitive E6/E7 type-specific polymerase chain reaction (PCR). STUDY DESIGN: Cross-sectional study. SETTING: Ear, nose, and throat department, university hospital. SUBJECTS AND METHODS: Paraffin-embedded tissues from tumor-free tonsils (TFTs) were evaluated for HPV DNA using GP5+/6+ consensus PCR and subsequent genotyping using E6/E7 type-specific PCR for HPV types 6, 11, 16, 18, 31, 33, 35, 39, 45, 51, 52, 53, 56, 58, 59, 66, and 68. The immunohistochemical expression of p16 and p53 was also assessed. RESULTS: In 80 TFTs, the authors identified 10 (12.5%) that tested positive for the following high-risk HPV types: HPV 16 (8 cases), 18 (1 case), and 31 (1 case). Twelve patients (15%) tested positive for HPV infection using the GP5+/GP6+ consensus primers but were negative using quantitative PCR. These patients were considered infected with low-risk HPV types. Fifty-eight TFTs (72.5%) tested negative for both GP5+/GP6+ and type-specific HPV PCR analysis (HPV negative). Among patients infected with HPV, the authors observed a slight increase in frequency with age. CONCLUSION: In TFTs, oncogenic and nononcogenic HPVs were present at a relatively high frequency in children and adults. The presence of high-risk HPV DNA in young children supports the horizontal transmission hypothesis and argues in favor of HPV vaccination at birth. [less ▲]

Background: Inadequate serum vitamin D is associated with secondary hyperparathyroidism, increased bone turnover, and bone loss, which increase fracture risk. Osteomalacia has also been observed in severe cases. Indeed, vitamin D and calcium are essential components of management strategies for the prevention and treatment of osteoporosis. Despite this, many people currently do not have adequate vitamin D levels. This problem has been documented in many studies around the world, regardless of age, health status, or latitude, and is especially common among older adults, who are also likely to have osteoporosis. Factors that contribute to low vitamin D include low exposure to sunlight, decreased synthesis in skin and reduced intestinal absorption related to aging, and limited dietary sources. Supplementation is the most effective means of correcting poor vitamin D nutrition. However, few patients with osteoporosis currently take sufficient vitamin D supplements. Scope: This review article discusses the role of vitamin D in osteoporosis and skeletal health, and summarizes what is known about the high prevalence of inadequate serum vitamin D and recommendations for supplementation. Conclusion: Greater awareness of the importance of vitamin D for skeletal health and more aggressive supplementation efforts are urgently needed to address this important public health problem.

The present study was designed to visit elderly women living in nursing homes and to compare their femoral neck bone mineral density (BMD) and circulating levels of parathyroid hormone (PTH) and 25-OH vitamin D (25-OHD) with those of subjects living at home, in the immediate vicinity of the nursing homes. Of 1483 women, aged 70 years and older, who were selected, 993 agreed to participate in this trial. Their femoral neck BMD (n = 993) was measured by dual-energy X-ray absorptiometry, with a specific device installed in a mobile truck. The circulating levels of 25-OHD and PTH were assessed after an overnight fast (n = 748). After stratification for age, there were no significant differences in mean femoral neck BMD values, prevalence of femoral neck osteoporosis, mean serum 25-OHD and prevalence of absolute or relative 25-OHD deficiency between the two groups. Serum levels of PTH were significantly higher in women over 80 years old living in nursing homes, compared with the community-dwelling women. After adjustment for age, a significant relation was found between femoral neck BMD and PTH levels in the whole population (p = 0.004) and in community-dwelling subjects (p = 0.039). When stratifying our population by quartiles of serum PTH values, the odds ratios for femoral neck osteoporosis were significantly increased for the top two quartiles compared with the lowest one both before (p = 0.00146) and after (p = 0.0013) adjustment for age and type of housing. From this study we conclude that femoral osteoporosis is largely underestimated in European women. Living in a nursing home is not, per se, a risk factor for decreased femoral BMD, and circulating PTH levels are a key determinant of low femoral bone density and osteoporosis. [less ▲]

Context: Prevalence data are important for assessing the burden of disease on the health care system; data on pituitary adenoma prevalence are very scarce. Objective: The objective of the study was to measure the prevalence of clinically relevant pituitary adenomas in a well-defined population. Design: This was a cross-sectional, intensive, case-finding study performed in three regions of the province of Liège, Belgium, to measure pituitary adenoma prevalence as of September 30, 2005. Setting: The study was conducted in specialist and general medical practitioner patient populations, referral hospitals, and investigational centers. Methods: Three demographically and geographically distinct districts of the province of Liège were delineated precisely using postal codes. Medical practitioners in these districts were recruited, and patients with pituitary adenomas under their care were identified. Diagnoses were confirmed after retrieval of clinical, hormonal, radiological, and pathological data; full demographic and therapeutic follow-up data were collected in all cases. Results: Sixty-eight patients with clinically relevant pituitary adenomas were identified in a population of 71,972 individuals; the mean (± SD) prevalence was 94 ± 19.3 cases per 100,000 population (95% confidence interval, 72.2 to 115.8). The group was 67.6% female and had a mean age at diagnosis of 40.3 yr; 42.6% had macroadenomas and 55.9% underwent surgery. Prolactinomas comprised 66% of the group, with the rest having nonsecreting tumors (14.7%), somatotropinomas (13.2%), or Cushing’s disease (5.9%); 20.6% had hypopituitarism. Conclusion: The prevalence of pituitary adenomas in the study population (one case in 1064 individuals) was more than 3.5–5 times that previously reported. This increased prevalence may have important implications when prioritizing funding for research and treatment of pituitary adenomas. [less ▲]

Malaria remains a major public health problem in the Democratic Republic of Congo (DRC) with 14 million cases reported by the WHOMalaria Report in 2014. Asymptomaticmalaria cases are known to be prevalent in endemic areas and are generally untreated,resulting in a significant source of gametocytes that may serve as reservoir of disease transmission. Considering that microscopycertainly underestimates the prevalence of Plasmodium infections within symptomatic carriers and that PCR assays are currentlyrecognized as the most sensitive methods for Plasmodium identification, this study was conducted to weigh the asymptomatic carriage in DRC by a molecular method. Six provinces were randomly selected for blood collection in which 80 to 100 individuals were included in the study. Five hundred and eighty blood sampleswere collected andmolecular diagnosiswas performed. Globally, almost half of the samples collected from asymptomatic individuals (280/580; 48.2%) had Plasmodium infections and the most species identified was P. falciparum alone in combination with P. malariae. The high prevalence reported here should interpellate the bodies involved in malaria control in DR Congo to take into account asymptomatic carriers in actions taken and consider asymptomatic malaria as a major hurdle for malaria elimination.

Abstract Production of SPARC/osteonectin/BM-40 was determined in mouse B16 melanoma clones BL6 and F10 (high metastatic) and F1 (low metastatic). SPARC was produced greater amount in BL6 and F10 than in F1 cells, showing a good agreement with their metastatic potentials. Moreover, SPARC production was not influenced by culture pH, even in the acidic conditions (= pH 5.9). Although tumor tissues show often low pH due to excessive amount of acidic metabolites such as lactate, most studies have been done in neutral pH. High SPARC production in the acidic medium, therefore, is thought to be an important potential for tumor invasive behaviour. [less ▲]

Dietary composition affects body composition; the role of fat and carbohydrates is well documented. Proteins are more satiating than carbohydrates, may produce different effects on glycemia , and are more thermogenic. Indeed the efficiency of cellular conversion of energy to high-energy yielding phosphate bonds from fatty acids is 90%, from carbohydrates 75%, but only 55% for amino acids. High-protein diets produced greater weight loss in some studies of obese humans but not others. Other human studies found that although the high-protein diet did not promote weight loss in excess of control diets, it did preserve lean tissue mass and promoted the loss of fat tissue . Companion animals also suffer from obesity , and a high-protein, energy-restricted diet was successful in reducing the body weight and body fat of overweight dogs and cats , and in conserving lean body mass of dogs . However, there have been few studies of the effects of protein intake on the body composition in normal-weight individuals of any species. The current study aimed to determine the effect of a limited energy intake of a high-protein diet on the body composition and least observed metabolism (LOM)5 of adult neutered cats. [less ▲]
