Background: Early referral to palliative care services in patients with advanced cancer is widely accepted. In addition, the use of futile intervention at the end of life is a pivotal aspect of assessing quality of care at that time.

Objectives: To evaluate the use of palliative care and aggressive treatments during the last month of life in women with gynecological malignancies.

Methods: The study was designed in two steps. The first step included a retrospective analysis of a gynecologic oncology cohort that underwent end-of-life (EOL) care. In the second part, a questionnaire regarding EOL care was completed by family members. Since our palliative care service became more active after 2014, we compared data from the years 2013–2014 to the years 2015–2019.

Results: We identified 89 patients who died from gynecological malignancy during study period; 21% received chemotherapy and 40% underwent invasive procedures during their last month of life. A palliative care consultation was documented for 49% of patients more than one week before their death. No statistical difference was achieved between the two time periods regarding the use of chemotherapy or invasive procedures in the last month of life. Nonetheless, after the incorporation of palliative medicine more women had palliative care consultations and had EOL discussions. Most of the patients’ relatives were satisfied with EOL care.

Conclusions: Many aggressive interventions were given during the last month of life. EOL discussions were documented in the medical charts of most patients and the rates increased with time.

Background: Leptin is a 16 kDa hormone synthesized by adipocytes and involved in body weight regulation.

Objectives: To determine serum leptin concentrations in heart, liver and kidney transplant recipients.

Methods: We investigated 57 patients: 18 male heart transplant recipients (age 25-69 years) at 1-66 months after transplantation, 6 female and 8 male liver transplant recipients (age 33-70) at 11-73 months after transplantation, and 10 female and 15 male kidney transplant recipients (age 20-61) at 3-138 months after transplantation. All recipients were receiving immunosuppressive therapy, including prednisone 0-20 mg/day, azathioprine 75-125 mg/day, cyclosporin 100-250 mg/day or tacrolimus 2-10 mg/day. The results were compared to those of 10 female and 10 male healthy controls. Morning serum concentrations of leptin were measured with a commercial radioimmunoassay (Linco Research Inc., USA), and serum insulin and cortisol levels were measured by radioimmunoassay.

Results: Patients (both men and women) after heart, liver and kidney transplantation exhibited significantly higher serum concentrations of leptin and leptin/body mass index ratios than controls. Serum leptin concentrations were significantly higher in women than in men and correlated very significantly with BMI[1] in all cases. The multivariate stepwise analyses showed that among parameters including BMI, gender, age, time after transplantation, prednisone dose, hematocrit, serum concentrations of glucose, albumin, creatinine, cortisol and insulin, only BMI, gender, cortisol and insulin were significant independent determinants of serum leptin levels in these patients.

Conclusions: This is the first report showing that, in addition to body mass index and gender, basal cortisol and insulin levels affect the hyperleptinemia in transplant patients. The clinical relevance of hyperleptinemia in these patients will require further investigation.
