Health-related quality-of-life trajectories during/after surgery and adjuvant chemotherapy in patients with colon cancer.

PURPOSE: This study aims to evaluate quality of life trajectory during the first year after surgical treatment in patients with resectable primary colon cancer. METHODS: Patients with resectable primary colon cancer diagnosed between 2013 and 2019 who received surgical treatment and adjuvant chemotherapy if indicated were selected from the Prospective Dutch ColoRectal Cancer cohort study (PLCRC). Health-related quality of life (HR-QoL) was assessed using EORTC-QLQ-C30 questionnaire before surgery, and three and twelve months after surgery. HR-QoL scores varied between 0 and 100 and outcomes were compared according to age (< 70 years, ≥ 70 years), comorbidity (yes, no) and treatment type (adjuvant chemotherapy, surgical treatment only). The extent of resilience, defined as a recovery of HR-QoL to baseline level after a clinically relevant decline in HR-QoL at months, was calculated twelve months post-surgery. RESULTS: For all 458 patients, the mean age was 66.4 years (SD 9.5), 40% were aged 70 years and older and 68% were men. Baseline level of HR-QoL summary score was relatively high with a mean of 87.9 (SD 11.5), and did not significantly differ between older and younger patients. The strongest decline of HR-QoL compared to baseline was observed at three months with a gradual recovery over time. Fourteen percent of all patients were non-resilient or showed a late decline at twelve months post-surgery. Compared to younger patients, older patients who received adjuvant chemotherapy were less resilient (respectively, 53 and 32%, p = 0.07) and at risk of a late decline in HR-QoL 1 year post-surgery (respectively, 3% versus 16%, p = 0.02). Comorbidity status had no significant impact on the HR-QoL trajectory. CONCLUSION: Colon cancer treatment was associated with a decline in HR-QoL three months post-surgery, but most patients return to baseline level within twelve months. Still, particularly older patients who received adjuvant chemotherapy were less resilient and at risk of a late decline in HR-QoL. These data could help in patients counselling regarding colon cancer treatment.

Study objectives in clinical trials in older patients with solid malignancies: do we measure what matters?

PURPOSE: We set out to determine study objectives of clinical trials which included older patients with the four most common malignancies, to assess the extent to which the inclusion of patient-related outcomes (PROs) has changed over the last fifteen years. METHOD: A search of the National Institutes of Health clinical trial registry was performed to identify currently recruiting or completed phase II or III clinical trials started between 2005 and 2020, which addressed chemotherapy or immunotherapy in patients aged > 65 years with the four most common solid malignancies. Trial characteristics and study objectives were extracted from the registry website. RESULTS: Compared to disease- and treatment-related outcomes, PROs were the least measured outcomes. Of the 1,663 trials, PROs were addressed in only 21% of all trials, in which quality of life as primary objective was found in less than 1% of all trials. Compared to all trials, trials exclusively for older patients addressed more often PROs (respectively, 30% vs 21%, p < 0.001). Over the last fifteen years, there was an incremental trend in the reporting of PROs from 17 to 24% of all trials (p = 0.007). CONCLUSION: Despite a slight incremental trend over the past 15 years, PROs appear to be underrepresented in clinical trials which include patients with a solid malignancy. In order to provide physicians and older patients with cancer realistic information about the impact of chemo- or immunotherapy on quality of life or functioning, researchers should strongly consider including PROs in their future clinical trials.

Treatment patterns and primary reasons for adjusted treatment in older and younger patients with stage II or III colorectal cancer.

OBJECTIVE: This study aims to assess age-related treatment patterns and primary reasons for adjusted treatment in patients with colorectal cancer. METHODS: Patients with colorectal cancer stage II or III diagnosed between 2015 and 2018 in the Netherlands were eligible for this study. Data were provided by the Netherlands Cancer Registry and included socio-demographics, clinical characteristics, treatment patterns and primary reasons for adjusted treatment. Treatment patterns and reasons for adjusted treatment were analysed according to age groups. RESULTS: Of all 29,620 patients, 30% were aged <65 years (n = 8994), 34% between 65 and 75 years (n = 10,173), 27% between 75 and 85 years (n = 8102) and 8% were ≥85 years (n = 2349). Irrespective of cancer location or stage, older patients received less frequently a combination of surgery and (neo)adjuvant therapy compared to younger patients (decreasing from 55% to 1% in colon cancer patients, and from 71% to 23% in rectal cancer patients aged <65 years and ≥85 years respectively). Omission of surgical treatment increased with age in both patients with colon cancer (ranging from 1% in patients aged <65 years to 16% in those ≥85 years) and rectal cancer (ranging from 12% in patients aged <65 years to 56% in those ≥85 years). The most common reasons for adjusted treatment were patient preference (27%) and functional status (20%), both reasons increased with advancing age. CONCLUSIONS: Guideline non-adherence increased with advancing age and omission of standard treatment was mainly based on patient preference and functional status. These findings provides insight in the treatment decision-making process in patients with colorectal cancer. Future research is necessary to further assess patient's role in the treatment decision-making process.

Perceived social support in patients with endometrial or ovarian cancer: A secondary analysis from the ROGY care study.

OBJECTIVE: Social support may reduce the amount of psychological distress and increase quality of life. This study assessed whether socio-demographic, personality, and clinical characteristics predict the level of perceived social support in patients with endometrial or ovarian cancer. METHODS: Patients with endometrial or ovarian cancer who participated in the ROGY Care study and completed the Multidimensional Scale of Perceived Social Support(MSPSS) 12 months after inclusion were eligible for this study (n=238). Logistic regression analysis was conducted to determine the predictive value of socio-demographic characteristics, personality and clinical characteristics after initial treatment on the perceived level of social support after 12 months. RESULTS: Of the 238 patients (mean age 64.8 ± 9.4 years), 139 patients had endometrial cancer (58%) and 99 patients had ovarian cancer (42%). One year after inclusion, the level of perceived social support was high in 79% of all patients (n=189). Patients experiencing low level of perceived social support (n=49) less often had a partner (69% versus 83% in patients with high level of perceived social support; p=0.029), had a higher education level (24% versus 15% respectively; p=0.013) and a distressed (type D) personality was more common (40% versus 16% respectively; p<0.001). In multivariable analysis, a type D personality, characterized by negative affect and social inhibition, was the only independent predictor of a low level of perceived social support (OR 2.96; 95% CI 1.37-6.37; p=0.006). CONCLUSIONS: In patients with endometrial or ovarian cancer, the level of perceived social support is mainly associated with a distressed (type D) personality. Those patients can be at risk of experiencing less social support. Future research is needed to assess whether they might benefit from additional support during cancer diagnosis and treatment.

Influence of disease process and duration on acute phase proteins in serum and peritoneal fluid of horses with colic.

BACKGROUND: The acute phase proteins (APP) serum amyloid A (SAA), haptoglobin, and fibrinogen are valuable blood biomarkers in equine inflammatory diseases, but knowledge of factors influencing their concentrations in blood and peritoneal fluid (PF) of horses with colic is needed. OBJECTIVES: The objective of this study was to investigate the influence of demographics (age, sex, breed), disease process (simple obstruction, strangulating obstruction, inflammatory), disease location, disease duration, hypovolemia, and admission hospital on concentrations of APP, lactate and white blood cell counts (WBC) in horses with colic admitted to 2 referral hospitals. ANIMALS: The study included 367 horses with colic admitted at 2 referral hospitals. METHODS: Prospective multicenter observational study of clinical data, as well as blood and PF biomarkers. Associations between biomarker concentrations and clinical variables were analyzed using multivariate linear regression analysis. RESULTS: Increasing pre-admission duration of colic was associated with increased concentrations of APP in blood and PF. Blood concentrations of SAA and fibrinogen were associated with disease process (inflammatory, strangulations, simple obstructions) in more colic duration groups (5-12 and >24 hours) than any of the other biomarkers. No relevant associations between demographic factors, hospital, or hydration status and the measured biomarkers were found. CONCLUSIONS AND CLINICAL IMPORTANCE: In horses with colic, concentrations of APP are associated mainly with disease process and duration of colic and may thus be used for assessment of disease independently of demographic or geographic factors. Serum amyloid A may be a diagnostic marker for use in colic differential diagnosis, but further evaluation is needed.

An evaluation of the impact of a community-based adherence support programme on ART outcomes in selected government HIV treatment sites in South Africa.

This study assessed the impact of a community-based adherence support service on the outcomes of patients on antiretroviral therapy (ART). The evaluation was a retrospective study based on patient clinical records. This study noted that a significantly higher proportion of patients with a community-based adherence supporter (also known as a patient advocate, PA) had viral load (VL) of less than 400 copies/ml at six months of treatment (70%, p=0.001); a significantly higher proportion of patients with PAs (89%) attained a treatment pickup rate of over 95% (67%; p=0.021). Patients at health facilities with PA services maintained a suppressed VL for a longer period as opposed to patients at health facilities without PA services (p=0.001), also patients at health facilities with PA services remained in care for longer periods (p=0.001). Therefore, the study concludes that integrated community-based adherence support is crucial in ensuring that patients remain in care, regularly pickup their treatment from ART clinics and are virologically suppressed. The study also underscores the importance of access to health services and the presence of an enabling environment in the treatment of AIDS.

Serial haematology results in transfused and non-transfused dogs naturally infected with Babesia rossi.

This prospective longitudinal study investigated the progression of haematological changes in 32 transfused and 54 non-transfused dogs naturally infected with Babesia rossi over the 1st 6 days following diagnosis and treatment. The effect of patient age on the results of complete blood counts was determined. Haematology data were analysed at presentation and at 24 hours, 3 days and 6 days after presentation. Dogs were treated with diminazene aceturate at diagnosis and a blood transfusion was given if deemed clinically required. Mildly to moderately regenerative normocytic normochromic anaemia was observed in all dogs throughout the study period. Transfused dogs more often had an inflammatory leukogram at presentation and at 24 hours, than dogs that were not transfused. In dogs with a left shift, a concurrent normal or decreased segmented neutrophil count was found more commonly than neutrophilia. Severe thrombocytopenia that resolved within a week was common. Blood transfusion alleviated the anaemia, but had no significant effect on white blood cell or platelet responses. Blood cell responses were not significantly influenced by age. In conclusion, the red blood cell and white blood cell responses were less than expected in dogs with babesiosis, given the degree of anaemia and inflammation present. The magnitude of thrombocytopenia and rapid return of the platelet count to normal suggested a possible immune-mediated mechanism for the thrombocytopenia.

Interference detection in implantable defibrillators induced by therapeutic radiation therapy.

BACKGROUND: Electromagnetic fields and ionising radiation during radiotherapy can influence the functioning of ICDs. Guidelines for radiotherapy treatment were published in 1994, but only based on experience with pacemakers. Data on the influence of radiotherapy on ICDs is limited. OBJECTIVES: We determined the risk to ICDs of interference detection induced by radiotherapy. METHODS: In our study we irradiated 11 ICDs. The irradiation was performed with a 6 megavolt photon beam. In each individual device test, a total of 20 Gray was delivered in a fractionated fashion. During each irradiation the output stimulation rate was monitored and electrogram storage was activated. In case of interference the test was repeated with the ICD outside and the lead(s) inside and outside the irradiation field. RESULTS: With the ICD inside the irradiation field, interference detection was observed in all ICDs. This caused pacing inhibition or rapid ventricular pacing. Ventricular tachycardia (VT) or ventricular fibrillation (VF) detection occurred, which would have caused tachycardia-terminating therapy. If the ICD was placed outside the irradiation field, no interference was observed. CONCLUSION: Interference by ionising radiation on the ICDs is demonstrated both on bradycardia and tachycardia therapy. This can have consequences for patients. Recommendations for radiotherapy are presented in this article.

Achieving social change on gender-based violence: a report on the impact evaluation of Soul City's fourth series.

The Soul City Institute for Health and Development Communication--a South African multi-media health promotion project--together with the National Network on Violence Against Women, formulated an intervention to address domestic violence. Recognising that behavioural change interventions aimed solely at individuals have limited impact, the intervention was designed to impact at multiple mutually reinforcing levels; individual, community and socio-political environment. The intervention and its evaluation results are presented. Soul City successfully reached 86%, 25% and 65% of audiences through television, print booklets and radio, respectively. On an individual level there was a shift in knowledge around domestic violence including 41% of respondents hearing about the helpline. Attitude shifts were also associated with the intervention, with a 10% increase in respondents disagreeing that domestic violence was a private affair. There was also a 22% shift in perceptions of social norms on this issue. Qualitative data analysis suggests the intervention played a role in enhancing women's and communities' sense of efficacy, enabling women to make more effective decisions around their health and facilitating community action. The evaluation concluded that implementation of the Domestic Violence Act can largely be attributed to the intervention. While demonstrating actual reductions in levels of domestic violence was not possible, the evaluation shows a strong association between exposure to intervention components and a range of intermediary factors indicative of, and necessary to bring about social change. This paper reports on the evaluation, discusses its limitations and challenges as well as lessons learned regarding multi-level interventions on domestic violence.

The acceptability of the female condom: perspectives of family planning providers in New York City, South Africa, and Nigeria.

This article seeks to fill the gap in female condom acceptability research by examining family planning (FP) providers' attitudes and experiences regarding the female condom in three countries (South Africa, the US, and Nigeria) to highlight providers' potential integral role in the introduction of the female condom. The case studies used data drawn from three independent projects, each of which was designed to study or to change FP providers' attitudes and practices in relation to the female condom. The case study for New York City used data from semistructured interviews with providers in one FP consortium in which no special female condom training had been undertaken. The data from South Africa were drawn from transcripts and observations of a female condom training program and from interviews conducted in preparation for the training. The Nigerian study used observations of client visits before and after providers were trained concerning the female condom. In New York City, providers were skeptical about the contraceptive efficacy of the female condom, with only 8 of 22 providers (36%) reporting they would recommend it as a primary contraceptive. In South Africa, providers who had practiced insertion of the female condom as part of their training expressed concern about its physical appearance and effects on sexual pleasure. However, they also saw the female condom as a tool to empower clients to increase their capacity for self-protection. Structured observations of providers' counseling interactions with clients following training indicated that Nigerian providers discussed the female condom with clients in 80% of the visits observed. Despite the lack of a uniform methodology, the three case studies illuminate various dimensions of FP providers' perceptions of the acceptability of the female condom. FP providers must be viewed as a critical factor in female condom acceptability, uptake, and continued use. Designing training programs and other interventions that address sources of provider resistance and enhance providers' skills in teaching female condom negotiation strategies may help to increase clients' use of the female condom.

Introducing the female condom through the public health sector: experiences from South Africa.

The successful implementation of new public health policy is influenced by provider preparedness and user acceptability of the new intervention. This paper describes the development and implementation of a participatory Training of Trainers (TOT) programme as a precursor to launch the South African government's female-initiated HIV prevention strategies in public health clinics. Three hundred peer-trainees from throughout South Africa were trained through a comprehensive, modular and interactive three-day workshop. The workshop content included: HIV/AIDS knowledge, beliefs and attitudes; values clarification regarding HIV infection and sexuality; sexual desensitization; 'hands-on' training in the use of and introduction of the female condom; and counselling, communication and programme planning skills. The TOT generated a cadre of knowledgeable health care workers for training others and provided a support structure at the service delivery level for ensuring potential users' access to the female condom within each province. Qualitative assessments of the training and trainer debriefing sessions suggest that the training was successful in increasing knowledge and promoting positive attitudes about female condoms. In addition, the expanded repertoire of problem-solving approaches left providers feeling confident about recommending this method to clients.

[Interaction between the veterinarian, the client and the patient]. / Interaksies tussen veearts, kliënt en pasiënt.

From the literature it has been established that pets can fulfill specific functions with regard to their owners. The purpose of this investigation is to highlight the interaction which takes place between pet owners and their pets as observed during consultations with veterinarians. The emphasis is however on the meaning of the emotional content of the interaction rather than on the actual functioning of the interaction. The interactions were monitored by means of natural observation, information gained through the completion of questionnaires, information about the client obtained from the veterinarian and content analysis of taped conversations which took place during consultations. The results indicate that the interaction between a pet owner and a pet is one of need fulfillment. Content analysis indicated that the owners attempt to fulfill certain needs through their pets, or conversely attempt to project their own emotions onto their pets. Loneliness and aggression are typical examples of this. A veterinarian who is able to identify his client's emotional needs, can alleviate his problems by giving unconditional support, referring the client with serious emotional problems to a psychologist or consulting a psychologist on behalf of the client.
