RESUMO

AIM: In the present study, the effect of chemo and radio therapies on serum trace elements content and antioxidant activity in blood serum of cervical cancer patients was evaluated. METHODS: Among 104 cervical cancer patients selected for the present study, 54 and 50 patients were treated with chemo- and radiotherapy respectively. Plasma Se, Zn, Cu and some enzymatic antioxidants activities were estimated in serum before and after the treatment. RESULTS: The decreased levels of serum trace elements, glutathione peroxidase activity and total antioxidant capacity, and increased malondialdehyde, glutathion reductase was observed in cervical cancer patients when compared to healthy controls. The increased concentration of serum Se, Zn was observed in patients treated with chemotherapy. Simultaneously there was a significant (P < 0.001) increase in glutathione peroxidase and total antioxidant capacity, and significant decrease (P < 0.05) in malondialdehyde and glutathion reductase levels in the serum of patients treated with chemotherapy compared to the patients treated with radiotherapy. CONCLUSION: The results demonstrated that chemotherapy but not radiotherapy results in significant increase in the trace elements levels and antioxidant activities in blood serum of cervical cancer patients.

RESUMO

INTRODUCTION: the UK has one of the highest rates of self harm in Europe, around 400 per 100,000 people (Horrocks et al. 2002). It accounts for 150,000 attendances to the Emergency department each year and is one of the top five causes of acute medical admissions in the UK (NICE 2002). AIMS: objectives included to explore the method of self harm and the demographic factors of those presenting the Emergency department with self harm. In addition we wanted to review the exploration of suicide risk factors and suicide intent by the Emergency department doctor and ascertain whether a psychiatric assessment with full mental state examination had been conducted with referral to psychiatric services if deemed necessary. We wanted to explore the current practice around self harm presentations in the Emergency department accordance with NICE guidelines. METHODS: data was collected retrospectively from February to August 2009. Twenty-five sets of medical notes were collated at random for patients who had presented with self harm to the Emergency department. Notes were reviewed for evidence of exploration of the event, psychiatric assessment, risk factors for suicide and further referral. RESULTS: 14 of the 25 patients presented having taken an overdose. 9 had inflicted some other form of self injury, namely lacerations to self. In 2 cases a mixed presentation was found. Previous psychiatric history was documented in 16 cases. 11 had a previous history of depression or anxiety disorder; 1 was known to have bipolar affective disorder; 1 was diagnosed in the past with borderline personality disorder; and 3 patients had no previous history. In 9 cases previous history was not documented. DISCUSSION: twenty-five sets of medical notes were reviewed from February to August 2009 for individuals presenting to the Emergency department with self harm. Of those, 12 fell into the over 25 age group. 17 were female and 8 were male. The majority of patients were of white British ethnicity. 14 had taken an overdose; 9 had inflicted some other form of self injury; and 2 had a mixed presentation. Suicide risk factors and suicidal intent was poorly documented with mental state examination found not to be documented in all 25 cases reviewed. 18 were deemed medically fit in the Emergency department and were referred for psychiatric review. These unfortunate findings may be a reflection on the time pressures faced by Emergency department doctors, namely the four hour targets, and perhaps lack of adequate training in psychosocial risk assessment. With such poor documentation made by the Emergency department doctors, a proforma was produced which incorporates suicide risk factors and assessment of suicide intent in addition to a brief version of the mental state examination. CONCLUSION: concerns have been raised by the recent Royal College of Psychiatrists report on self harm, that current level of care provided to service users fall short of the standards set out in policies and guidelines, with poor assessments, unskilled staff and insufficient care pathways (Royal College of Psychiatrists. Report CR 158. 2010). Indeed evidence suggest that appropriate training and intervention given to A&E staff can lead to improvements in the quality of psychosocial assessment of patients with deliberate self harm (Crawford et al. 1998).

RESUMO

The detection of intracellular forms of Notch1 in human cervical cancers more than a decade ago prompted an investigation into the possible role of this pathway in driving these cancers. These tumors are consistently characterized by features of deregulated ligand-dependent signaling. Although Notch signaling complements the function of papillomavirus oncogenes in transformation assays of human keratinocytes, there are dose-dependent effects, which inhibit growth of established cervical cancer cell lines. Two pro-oncogenic effector mechanisms that have been suggested to operate in this context by Notch signaling are the activation of PI3K/Akt pathway and the upregulation of c-Myc. Collectively, there is a complex interplay between Notch signaling and papillomaviruses in the context of cervical carcinogenesis. Better animal model systems and identification of human cervical cancer stem cells should help clarify the possible stage specific and pleiotropic effects and regulation of Notch signaling.

RESUMO

In our endeavor to design and synthesize novel anticancer agents, a new series of indoloquinazoline compounds were prepared and tested initially for anticancer activity in vitro against a panel of human cancer cell lines. Most of these compounds exhibited cytotoxic activity in in vitro screens. Compounds were selected and further evaluated using a modified Hollow Fiber Assay for their preliminary in vivo activity against 12 cell lines implanted in the subcutaneous and intraperitoneal compartments in mice. The results indicate that these compounds may constitute a new class of anticancer agents.
