Outcomes for adults with anorexia nervosa who do not respond early to outpatient treatment
2021
Objective: To better understand those patients with anorexia nervosa who do not show early response to treatment and are likely to have poorer outcome. Method: From an existing data set of 187 patients with anorexia nervosa across 22 eating disorder outpatient services in the United Kingdom, participants who had started treatment and had at least one body mass index (BMI) observation in the first 6 weeks of treatment were eligible for these secondary analyses (N = 65), a latent class analysis of BMI change over the first 6 weeks of treatment. Fifty-six patients showed no early change in BMI. We used logistic regression to examine predictors of good outcome in the 40 participants who had 12-…
Changes in the sense of agency: Implications for the psychotherapy of bulimia nervosa- A case study.
2019
A sense of agency is a transtheoretical concept that increases our understanding of important processes in psychotherapy. Agency can be described in terms of how strongly the person believes that she can have an impact on her problematic experiences and behaviors. In this case study, a patient's sense of agency in relation to symptoms of bulimia nervosa was assessed during 3 years of psychotherapy. Five distinct phases of agency in relation to eating disorder symptoms were identified: A false sense of agency or no agency at all, a weak sense of agency, a nascent sense of agency, a wavering sense of agency, and a strong sense of agency. A better understanding of patient agency can facilitate…
Memory bias for schema-related stimuli in individuals with bulimia nervosa
2010
This study investigates whether individuals with bulimia nervosa (BN) have a memory bias in relation to explicit memory (cued and free recall vs. verbal and pictorial recognition tasks). Twenty-five participants diagnosed with BN and 27 normal controls (NC) were exposed to body-related, food-related, and neutral TV commercials, and then recall and recognition rates were assessed. Poorer recognition and recall of body-related stimuli was found for BN in comparison to NC, suggesting a memory bias. Results are discussed in relation to previous studies, along with suggestions as to how future studies can gain more insight into dysfunctions in information processing that can lead to the maintena…
Sexual disorders and dyspnoea among women with obstructive sleep apnea
2020
Abstract Purpose We aimed to assess sexual function, sexual distress and the prevalence of female sexual dysfunction (FSD) among women with obstructive sleep apnea syndrome (OSA), and to assess if the presence of OSA and dyspnea influences the prevalence of FSD, body image during sexual activity and sexual function. Methods We assessed 23 women with new OSA diagnosis and 23 healthy age and body mass index (BMI) matched controls. Sexual functions were evaluated by Changes in Sexual Functioning Questionnaire (CSFQ), sexual dysfunction was diagnosed based on DSM-5 criteria during the semi-structured sexual interview, whereas body image was evaluated by Body Exposure during Sexual Activities Qu…
FOCAL ACTIVE COLITIS AS A PREDICTOR OF INFLAMMATORY BOWEL DISEASE: RESULTS FROM A SINGLE-CENTER EXPERIENCE.
2017
The term focal active colitis (FAC) is conventionally used to describe the presence of isolated cryptitis, characterized by an inflammatory infiltrate consisting of intraepithelial neutrophils and/or neutrophils invading the lumen of the criptae, with no other microscopic alteration of the colonic mucosa and, in particular, without the presence of signs of chronic inflammation. To date, only four studies, including one conducted in a pediatric population, have been performed to evaluate the clinical significance of this disease. The aim of this retrospective study on prospectively-collected data is to evaluate the clinical implications of the focal active colitis, since there still remains …
Havep53 gene mutations and protein expression a different biological significance in colorectal cancer?
2002
p53 alterations are considered the most common genetic events in many types of neoplasms, including colorectal carcinoma (CRC). These alterations include mutations of the gene and/or overexpression of the protein. The aim of our study was to assess whether in 160 patients undergoing resective surgery for primary operable CRC there was an association between p53 mutations and protein over-expression and between these and other biological variables, such as cell DNA content (DNA-ploidy) and S-phase fraction (SPF), and the traditional clinicopathological variables. p53 mutations, identified by PCR-SSCP-sequencing analysis, were found in 68/160 patients (43%) and positive staining for p53 prote…
Prevalence and distribution of oral mucosal non-malignant lesions in the western Sicilian population.
2016
BACKGROUNG: The aim of the present study was to determine the prevalence of oral mucosal non-malignant lesions in the Sicilian population. In addition, we evaluated the association between each oral lesion and its risk factors. METHODS: This study analyzed a total of 2539 consecutive patients, attending the Department of Surgical, Oncological and Stomatological Disciplines of Palermo University, who were examined for the presence of various oral lesions during the period from January 2012 and February 2015. RESULTS: The sample consisted of 1330 (52%) female and 1209 (48%) male. The age ranged from 13-86 years with a mean age of 47.16 years. Among these subjects 1495 (58%), presented one or …
Thymidylate synthase gene promoter polymorphisms are associated with TSmRNA expressions but not with microsatellite instability in colorectal cancer
2005
Abstract BACKGROUND: Microsatellite instability (MSI) is a biological characteristic of most tumours, being involved in 85% of hereditary non-polyposis colorectal cancer (HNPCC). It also occurs in 10-15% of sporadic colorectal cancers (CRC). HNPCC appears to be caused by germline mutations in mismatch repair (MMR) genes, which are responsible for repairing single base-pair mismatches. MSI is also associated with a better response of CRC to adjuvant chemotherapy with fluoropyrimidines. We investigated any relationship between the MSI status and the TSmRNA expression, the polymorphisms of 5-Fluorouracil (5-FU cellular target, the enzyme thymidylate synthase (TS) and TS expression evaluated by…
β-Adrenoceptor stimulation up-regulates phosphodiesterase 4 activity and reduces prostaglandin E 2 -inhibitory effects in human neutrophils
2000
Human neutrophils were treated for 4 h with a combination of salbutamol (1 µM), a β2-adrenoceptor agonist, and rolipram (30 µM), a selective phosphodiesterase 4 inhibitor, to investigate whether this treatment produces up-regulation of phosphodiesterase activity with functional consequences. Anion-exchange chromatography coupled with the use of selective activators and inhibitors demonstrated that a phosphodiesterase activity with characteristics of the isoenzyme type 4 was increased in drug-treated cells. Kinetic analysis showed a ~1.5-fold increase in V max without alteration of K m values. The augmented phosphodiesterase activity in drug-treated cells was abolished by actinomycin D. Cycl…
15-Lipoxygenase expression and 15(S)-hydroxyeicoisatetraenoic acid release and reincorporation in induced sputum of asthmatic subjects
2000
Recent evidence shows that 15(S)-hydroxy-eicoisatetraenoic acid (15[S]-HETE) can be released and rapidly reincorporated into cellular lipids. These mechanisms exert several immunoregulatory functions that may be relevant in airway inflammation.Our purpose was to evaluate the levels of both soluble and cell-associated 15(S)-HETE and to examine 15-lipoxygenase (15-LO) messenger RNA (mRNA) expression in sputum samples obtained from 10 control and 18 asthmatic subjects.Levels of 15(S)-HETE were measured by reverse-phase HPLC separation followed by RIA in supernatants and in cell membrane-extracted phospholipids after acid hydrolysis. 15-LO mRNA was evaluated by primed in situ hybridization (PRI…
