Long-term treatment for emotional distress in women with breast cancer

Purpose: Breast cancer patients have many needs, including strategies to cope with the associated distress, during and after cancer treatment. Establishing and implementing adequate social and emotional support for these women, to reduce the detrimental effects of stress resulting from their treatment and disease, is the need of the hour. This study aims to assess how women, diagnosed and treated for breast cancer, combat emotional stress using mechanisms of coping and control and emotional defense, as well as to identify potential groups among them, with different long-term patterns and needs. Methods: 98 patients belonging to a local breast cancer support association (ALMOM), were enrolled in this study. A questionnaire specifically designed for them was administered, and its internal consistency and reliability assessed. A hierarchical clustering was employed to classify the women. The questionnaire focused on four sections, including personal feelings, coping strategies, environmental influences and maladaptive coping. Results: An adequate internal reliability was obtained with Cronbach's α near or greater than 0.60. Personal feelings were significant and clearly correlated with coping strategies and maladaptive coping. Three groups of women with different patterns of emotional characteristics and needs were identified: positivist, unsafe, and hopeless women, with different long-term emotional needs to be satisfied. Conclusions: Psychological therapeutic interventions should be maintained in many breast cancer patients over time, even after treatment completion, in order to consolidate adaptive and sustainable responses

Distribution of Flumequine in Intestinal Contents and Colon Tissue in Pigs after Its Therapeutic Use in the Drinking Water

Flumequine concentrations in plasma, colon tissue and intestinal contents were evaluated in 12 healthy pigs after oral administration (12 mg/kg every 24 h for 5 consecutive days in drinking water). Plasma, colon tissue and intestinal content samples were collected from animals sacrificed on days 3, 6 and 7. Concentrations were measured by high performance liquid chromatography after having validated the method, following the European Medicines Agency (EMA) requirements. The drug was not detected in any plasma sample. In colon tissue, concentrations were higher on day 3 (0.230 ± 0.033 µg/g, descending colon; 0.156 ± 0.093 µg/g, ascending colon) than on day 6 (0.187 ± 0.123 µg/g, descending colon; 0.107 ± 0.007 µg/g, ascending colon). Concentrations were considerably higher in intestinal contents, again on day 3 (1.349 ± 1.401 µg/g, descending colon; 0.591 ± 0.209 µg/g, ascending colon) than on days 6 (0.979 ± 0.346 µg/g, descending colon; 0.595 ± 0.075 µg/g, ascending colon) and 7 (0.247 ± 0.172 µg/g, descending colon; 0.172 ± 0.086 µg/g, ascending colon). Measured concentrations were lower than those effective against the most common intestinal pathogenic microorganisms in swine and, more specifically, Brachyspira hyodysenteriae

Influence of Plantago ovata husk (dietary fiber) on the bioavailability and other pharmacokinetic parameters of metformin in diabetic rabbits

Abstract Background Metformin is an oral hypoglycemic agent frequently used in patients with type 2 diabetes. In this study, we have investigated the influence of the dietary fiber Plantago ovata husk on the pharmacokinetics of this drug when included in the diet, as well as when administered at the same time as metformin. Methods Six groups of 6 rabbits were used. Groups 1 to 3 were fed with standard chow and groups 4 to 6 with chow supplemented with fiber (3.5 mg/kg/day). Groups 1 and 4 received metformin intravenously (30 mg/kg). Groups 2 and 5 received metfomin orally (30 mg/kg), and number 3 and 6 were treated orally with metformin (30 mg/kg) and fiber (300 mg/kg). Results The changes caused by the inclusion of fiber in the feeding were more important in groups that received oral metformin. In this way, metformin oral bioavailability showed an increase of 34.42% when rabbits were fed with supplemented chow. Conclusions Plantago ovata husk increased the amount of absorbed metformin when included in the diet (significant increase in AUC), and delayed its absorption when administered at the same time (significant increase in tmax)

Improvement of Albendazole Bioavailability with Menbutone Administration in Sheep

The pharmacokinetic interaction between a benzimidazole (albendazole, ABZ) and a choleretic drug (menbutone, MEN) was evaluated in sheep. The plasma disposition of albendazole sulfoxide (ABZSO, active metabolite) and albendazole sulfone (ABZSO2, inactive metabolite) was investigated following an oral administration of albendazole (ABZ) (5 mg/kg) alone or with menbutone (MEN) (intramuscular, 10 mg/kg). Blood samples were collected over 3 days post-treatment, and drug plasma concentrations were measured by high performance liquid chromatography (HPLC). ABZSO was measured from 0.5 to 48 h, and ABZSO2 from 2 to 60 h. No parent drug was detected at any sampling time. Mean maximum plasma concentration (Cmax) and the area under the plasma concentration-time curve (AUC) were 12.8% and 21.5% higher for ABZSO when ABZ and MEN were administered together, which indicates a significant increase in the amount absorbed. The rate of absorption was not modified, with similar values for the time to reach Cmax (tmax) (11.5 h with ABZ + MEN and 10.7 h with ABZ treatment), although no significant differences were observed for these latter pharmacokinetic parameters. Regarding ABZSO2, Cmax, AUC and tmax values were similar after both treatments (ABZ or ABZ + MEN). The results obtained indicate that co-administration of ABZ and MEN may be an interesting and practical option to increase the efficacy of this anthelmintic

Assessing the Expression of Emotions in Breast Cancer Survivors during the Time of Recovery: Perspective from Focus Groups

Breast cancer has major public health implications, as it is the most frequent malignant tumor and the leading cause of cancer death in women. Survivors have many needs, including strategies to cope with the associated distress. We explore whether focus groups are useful for nurses to obtain information about the emotional state of breast cancer women, and develop strategies for coping with the stress that this disease entails. A qualitative study was carried out, involving 25 focus groups with 83 women treated for breast cancer, recruited from the local Breast Cancer Association (ALMOM). Four open-ended questions were employed, and 60-min discussions were carried out. They were transcribed, analyzed, coded, and the themes identified. Four major themes emerged, including “complex emotional evolution”, “emotional isolation”, “lack of information” and “inability to give advice”. Women admitted that this disease had been a stressful factor for them, causing emotional (anxiety, irritability, anger or guilt) and cognitive disorders (confusion, lack of concentration, forgetfulness). The use of focus groups in breast cancer survivors allows nurses to evaluate the expression of emotions in these women, and collect and share information about their feelings, thoughts and experiences, so that survivors can cope more easily with the stress related to their illness

Face-to-face and online teaching experience on experimental animals and alternative methods with nursing students: a research study

Abstract Background Animal models are increasingly used in Nursing science to study care approaches. Despite the scientific relevance and the ethical debate surrounding the use of experimental animals, there is a scarcity of scholarly literature exploring this topic in Nursing Schools. Aim To evaluate perceptions and attitudes of nursing students enrolled in a Pharmacology course on the use of experimental animals and implementation of alternative methods, by comparing the experience for two academic years. An interdisciplinary collaboration has also been developed. Methods A descriptive cross-sectional, quantitative study was developed. Undergraduate nursing students were enrolled in the Pharmacology subject at the University of Leon (Spain). The study was carried out in the Pharmacology facilities. Students followed a two-session practical class regarding experimental animals and alternative methods in the Pharmacology course (Degree in Nursing) in two different academic years (2019–20/2020–21). At the end of the activity, they answered a questionnaire to assess their opinions on the use of experimental animals and alternative methods in Pharmacology and the 3Rs principle. Results A comparison of the students’ perception with and without direct participation in the evaluation of promazine effects in mice was made. A total of 190 students participated in the teaching experience, providing high scores in all items (4–5 out of 5 points) regarding the teaching experience. Students became also aware of the advantages and disadvantages on the use of experimental animals, as well as the ethical considerations to bear in mind for their use and the need for alternative methods. Conclusions In the students’ opinion, the total replacement of animals by alternative techniques was very difficult, and they preferred to do the practice face-to-face. The alternative method designed was useful for the students to accept the employment of experimental animals in biomedical research and education, and know the legislation applied in the protection of animals
