The new criteria for classification of rheumatoid arthritis: what we need to know for clinical practice.
2011
The new criteria for classification of Rheumatoid Arthritis have been recently released. They incorporate the anti-Citrullinated Protein antibody testing and the other classic criteria in a score system (the diagnosis of definite rheumatoid arthritis is made by a total score ≥6). These criteria try to meet the pressing needs to gain sensitivity in early disease. Symptoms, elevated acute-phase response, serologic abnormality, joint involvement were all considered for scoring after confirming the presence of synovitis in at least 1 joint in the absence of an alternative diagnosis that better explains the synovitis. However, no sensitivity and specificity has been showed. Moreover, Area Under …
Heart involvement in rheumatoid arthritis: systematic review and meta-analysis.
2013
Abstract Objective The aim of our study was to conduct a systematic review with meta-analysis of the current case–control studies about the valvular and pericardial involvement in patients with Rheumatoid Arthritis (RA), asymptomatic for cardiovascular diseases. Methods Case–control studies were identified by searching PubMed (1975–2010) and the Cochrane Central Register of Controlled Trials (CENTRAL) (1975–2010). Participants were adult patients with RA asymptomatic for cardiovascular diseases, and the outcome measure was the presence of cardiac involvement. Results Quantitative synthesis included 10 relevant studies out of 2326 bibliographic citations that had been found. RA resulted sign…
Halitosis: new insight into a millennial old problem.
2011
The problem of halitosis has been reported since ancienttimes. References have been found in papyrus manuscriptsdating back to 1550 BC. Hippocrates advised that any girlshould have pleasant breath, making sure always to washher mouth with wine, anise and dill seeds [1].More than50 years ago, Blackburn [2] investigated halitosis in a case-series of 73 patients affected by leukemia. He found apeculiar odor of the breath resembling that of a freshlyopened corpse. This characteristic smell is not associatedwith clinical involvement of the gum, mouth, or upperrespiratory or alimentary tract. He associated this particularsmell with the hematologic disease. Nearly 15 years ago,the role of cadaveri…
An uncommon clinical picture: Wellens’ syndrome in a morbidly obese young man
2010
A 39-year-old man presented to the emergency department (ED) of the ‘‘Paolo Giaccone’’ Academic Hospital, Palermo (Italy). He had anterior chest pain that did not radiate to the neck or arms. The patient came from home where the chest pain initiated. The patient was morbidly obese (BMI 54 kg/m). At the ED, the patient’s blood pressure was 120/80 mmHg, the serum troponin I concentration was 0.029 ng/ml (normal values \ 0.034, borderline 0.034–0.12), myoglobin 45 ng/ml (normal values \ 120). While experiencing chest pain, the patient underwent a standard 12 lead electrocardiogram (ECG) that was normal. An echocardiogram, also during the chest pain, excluded the presence of hypo-akinetic left …
Validation of two short questionnaires assessing physical activity in colorectal cancer patients
2018
Background In order to investigate the impact of adherence to recommendations of physical activity and sedentary time on health outcomes in clinical trials, there is a need for feasible tools such as questionnaires that can give representative estimates of these measures. The primary aim of the present study was to validate two such questionnaires and their ability to estimate adherence to the recommendations of physical activity defined as moderate-to- vigorous physical activity or moderate physical activity of at least 150 min/week in colorectal cancer patients. Secondarily, self-reported sedentary time from the HUNT-PAQ was also evaluated. Methods Participants from 'The Norwegian dietary…
Patterns of rapid weight loss in elite sambo athletes
2021
Abstract Background Rapid weight loss (RWL) is commonly practiced in combat sports. Both magnitude and methods used to induce RWL are largely similar among combat sports, but currently, there is no data on RWL methodology used by sambo athletes. Therefore, the aim of this study was to determine RWL procedures sambo athletes apply to lose weight rapidly. Methods The sample consisted of 199 participants, of which 132 males and 67 females who participated in the World Sambo Championship 2020 held in Novi Sad, Serbia. Each participant received RWL questionnaire that was available in multiple languages, and every participant was instructed how to fill it out. Results Almost 87% of sambo particip…
Comparison between logbook-reported and objectively-assessed physical activity and sedentary time in breast cancer patients: an agreement study
2017
BACKGROUND: Increasing physical activity (PA) and decreasing sedentary time (ST) have important health effects among breast cancer patients, a growing population group. PA and sedentary behaviors are complex multi-dimensional behaviors and are challenging to monitor accurately. To date few studies have compared self-reports and objective measurement in assessing PA and ST in women undergoing breast cancer treatments. The aim of the present study was to compare self-reports and objective measures for assessing daily time spent in moderate-intensity physical activity (MPA), vigorous-intensity physical activity (VPA) and ST in women undergoing breast cancer treatments. METHODS: Baseline data f…
Effect of CYP1A1 Gene Polymorphisms on Estrogen Metabolism and Bone Density
2004
UNLABELLED: In this study, we evaluated the effect of polymorphisms of the CYP1A1 gene, linked to hormone-related cancers, on estrogen metabolism and BMD. We found that variants carrying the A allele (CA and AA) for the C4887A polymorphism have a significantly higher degree of estrogen catabolism and lower femoral BMD. INTRODUCTION: Polymorphisms of the CYP1A1 gene, one of the key enzymes that metabolize estrogen, have been linked with hormone-related cancers. We investigated the impact of these polymorphisms on estrogen metabolism and BMD, which is another hormone-dependent health issue. MATERIALS AND METHODS: One hundred seventy postmenopausal women (mean age, 63.5 +/- 0.6 years) particip…
The induction of hepatic microsomal metabolism in rats following acute administration of a mixture of polybrominated biphenyls.
1976
Abstract Firemaster BP6, a mixture of polybrominated biphenyls (PBBs), was administered to female Sprague-Dawley rats (170–180 g) as a single ip injection at 25 and 150 mg/kg. Other animals received phenobarbital (PB), 3-methylcholanthrene (3MC), or PB and 3MC together. Animals were killed at intervals of 12, 24, 48, 192, and 336 hr after treatment with PBBs, or 24 hr after PB, MC, or PB-MC, and various hepatic microsomal parameters were measured. After 150 mg/kg of PBBs, cytochrome P450 concentrations reached a maximum by 48 hr (225% of control), then remained elevated through 336 hr. A similar pattern of induction was observed for epoxide hydratase and aniline hydroxylase activities. In c…
Progestogens reduce thromboxane production by cultured human endothelial cells.
2011
Objectives Progestogens have been poorly studied concerning their roles in endothelial physiology. Prostanoids are vasoactive compounds, such as thromboxane A2, a potent vasoconstrictor, and prostacyclin, a vasodilator. We examined the effects of two progestogens used clinically, progesterone and medroxyprogesterone acetate, on thromboxane A2 production by cultured human umbilical vein endothelial cells (HUVEC) and investigated the role of progesterone receptors and the enzymes involved in production of thromboxane A2 and prostacyclin. Methods Cells were exposed to 1‐100 nmol/l of either progesterone or medroxyprogesterone acetate, and thromboxane A2 production was measured in culture mediu…
