Mifepristone Increases Life Span in Female Drosophila Without Detectable Antibacterial Activity

Mifepristone dramatically increases the life span of mated female Drosophila while reducing the expression of innate immune response genes. Previous results indicated that mifepristone also reduced the load of aero-tolerant bacteria in mated females. Experiments were conducted to further investigate the possible role of bacteria in mifepristone life span effects. Life span was assayed in flies grown from sterilized eggs on autoclaved media and in normally cultured controls in two independent assays. Sterilization increased mated female life span (+8.3% and +57%, respectively), and the effect of mifepristone was additive (+53% and +93%, respectively). High-throughput sequencing of 16S sequences revealed that sterilization reduced the abundance of multiple species and the classes Bacteroidia, Bacilli, Actinobacteria, and Cytophagia. By contrast, mifepristone caused no decreases and instead increased the abundance of three species. Five aero-tolerant bacterial species were cultured from extracts of mated female flies, including both Gram-positive and Gram-negative species (Acetobacter sicerae, Enterococcus faecalis, Lactobacillus plantarum, Serratia rubidea, and Paenibacillus glucanolyticus). There was no detectable effect of mifepristone on the growth of these bacteria in vitro, indicating that mifepristone does not have a direct antibiotic effect. To test if antibiotics could mimic the effects of mifepristone in vivo, mated female flies were treated throughout adult life span with high concentrations of the individual antibiotics doxycycline, ampicillin, kanamycin, and streptomycin, in replicate experiments. No significant effect on life span was observed for ampicillin, kanamycin, or streptomycin, and an inconsistent benefit was observed for doxycycline. Finally, supplementation of media with Enterococcus faecalis did not alter adult female life span in the presence or absence of mifepristone. Taken together, the results indicate the life span benefits of mifepristone are not due to an antibiotic effect

Dealing with symptoms and issues of hospitalized patients with cancer in indonesia: the role of families, nurses, and physicians

Item does not contain fulltextOBJECTIVE: Patients with cancer often face physical, psychological, social, spiritual, and emotional symptoms. Our aim was to study symptoms and issues of hospitalized patients with cancer in Indonesia, a country with strong family ties, and how family members, nurses, and physicians deal with them. METHODS: In 2011, 150 hospitalized cancer patients in 3 general hospitals in Indonesia were invited to fill in a questionnaire, which was based on the validated Problems and Needs of Palliative Care (short version) questionnaire. Descriptive statistics were performed. RESULTS: Of 119 patients (79%) who completed the questionnaire, 85% stated that their symptoms and issues were addressed. According to these patients, financial (56%), autonomy (36%), and psychosocial (34%) issues were most often addressed by the family alone. Physical symptoms (52%) and spiritual issues (33%) were addressed mainly by a combination of family, nurses, and physicians. CONCLUSIONS: Hospitalized patients with cancer in Indonesia felt that most of their symptoms and issues had been addressed, and the family was highly involved. The strong family ties in Indonesian culture may have contributed to this family role. More research is needed to clarify how this influences patient outcome, quality of care, and quality of life of both the patients and their families, along with the degree of partnership between families and professionals. This information might help answer the question what advantages and disadvantages the family role in caring for a hospitalized patient with cancer generates for the patient, the family, and professional caregivers

Short-term immobilization after eccentric exercise. Part II : creatine kinase and myoglobin

BACKGROUND: Patients with advanced cancer experience problems and unmet needs. However, we assume that patients with advanced cancer will have more problems and unmet needs in a country with a lower economic status than in an economically stronger country. We studied whether patients with advanced cancer in Indonesia have more problems and unmet needs than a similar group of patients in the Netherlands. METHODS: We performed a cross-sectional survey. We compared the data for 180 Indonesian and 94 Dutch patients relating to 24 items of the Problems and Needs in Palliative Care-short version questionnaire. We performed descriptive and chi(2) analysis with Bonferroni correction. RESULTS: The prevalence of most physical problems, including pain, was similar in the 2 groups. In Indonesia, financial problems were the most common: 70 to 80% vs. 30 to 42% in the Netherlands. In Indonesia, 25 to 50% of the patients reported psychological and autonomy problems versus 55 to 86% in the Netherlands. The Indonesian group had many more unmet needs for each problem (> 54%) than the Dutch group (< 35%). CONCLUSION: Apparently, economic and cultural differences hardly influence physical problems. Nonetheless, fewer Indonesian patients reported psychological and autonomy problems than Dutch patients. This difference contradicts our hypothesis. However, we found more unmet needs for professional attention in Indonesia than in the Netherlands, which is compatible with our hypothesis. These simple comparative data provide interesting insights into problems and unmet needs and give rise to our new hypothesis about cultural influences. This hypothesis should be studied in more depth

Family caregivers' involvement in caring for a hospitalized patient with cancer and their quality of life in a country with strong family bonds

Item does not contain fulltextBACKGROUND: Being involved in caring for family members during illness is part of the Indonesian culture, even during hospitalization. It is unknown which factors influence the quality of life (QoL) of family members taking care of their loved ones. The present study aims to identify factors influencing the QoL of family caregivers of hospitalized patients with cancer in Indonesia. METHODS: A cross-sectional survey was performed. Data were collected in a general hospital in Yogyakarta from September to December 2011. Family caregivers of patients with cancer were invited to participate. Regression analysis was used to determine which aspects of caring and which demographic characteristics influenced their QoL. The Caregiver QoL Index-Cancer questionnaire was used to measure the QoL. RESULTS: One hundred of 120 invited caregivers (83%) completed the questionnaire. Being involved in psychological issues in caring (beta = 0.374; p = 0.000), younger age (beta = -0.282; p = 0.003), no previous caring experience (beta = -0.301; p = 0.001), and not being the spouse (beta = -0.228; p = 0.015) negatively influenced the QoL and explained 31% of the variation (adjusted R(2) = 0.312; F = 12.24; p = 0.000). Gender, education level, and time spent on caring did not influence the QoL of family caregivers. CONCLUSIONS: Our findings identified modifiable factors such as dealing with psychological issues and lack of experience in caring that negatively influenced the QoL of family caregivers. These factors are potential targets for intervention strategies. Education and intervention programs focusing on dealing with psychological problems in cancer care might improve the QoL of both patients and their families
