Psychosexual health in gynecologic cancer
More people are living with the long-term effects of cancer owing to improvements in cancer treatments and an aging population. Many people diagnosed with cancer report a negative impact on sexual identity, sexual functioning, and their sexual relationship. Gynecologic cancer survivors are often the most severely affected. These cancers involve cancers of the ovaries, uterus, cervix, vagina, and vulva. The impact of these cancers on sexual health results not only from the disease process itself, but may also be due to the necessary treatments required. These can have a profound impact on psychological, physiological, and social well-being both in the short and long term, which may result in negative impact on the quality of life of the patient as well as her partner. Although most patients express that they would like to be more informed about sexual health and would like to have the opportunity to discuss these issues with their therapeutic team, sexual health is often not discussed with the patient

Inventariação e propagação de Thymus mastichina na Beira Interior
Integrado no Programa Agro, Medida 8.1, Projecto nº 800, foram elaborados
estudos de distribuição e propagação da espécie Thymus mastichina L., existentes
espontaneamente na Beira Interior. Foram avaliadas seis zonas ecológicas distintas
denominadas Vale do Tejo, Beira Interior Sul, Cova da Beira, Beira Interior Norte,
Serra da Estrela e Serra da Gardunha.
Durante dois anos fez-se prospecção no campo em cada zona ecológica e
recolheu-se material vegetal. Realizaram-se ensaios de germinação em laboratório em
condições de temperatura alterna 10º/20ºC (dia) e temperatura constante 23ºC (dia),
com fotoperíodo de 8 e 16 horas/dia, respectivamente. Testou-se ainda a capacidade
germinativa em estufa, na Primavera e efectuaram-se ensaios de enraizamento, com
estacas terminais, em condições de Outono/Inverno e Primavera/Verão.
Na Beira Interior foram encontrados 36 locais onde se verificou a ocorrência de
Thymus mastichina. Em cada zona ecológica onde foram encontrados indivíduos da
espécie em estudo, foi seleccionado um local para recolha de 20 plantas-mãe, que foram
posteriormente instaladas no campo de caracterização/demonstração da ESACB.
Nos ensaios de germinação verificaram-se taxas entre os 80% e 94% em
laboratório e entre os 76% e 84%, em viveiro. Nos ensaios de propagação vegetativa de
estacas terminais obtiveram-se taxas de enraizamento entre os 20% e 100%
South African women’s perspectives on self-sampling for cervical cancer screening: A mixed-methods study
Background. Self-sampling as a method of screening for cervical cancer and its precursors is an attractive option for low-resource settings. However, to allow successful integration of self-sampling into national screening programmes, it is necessary to understand women’s perceptions and beliefs surrounding this method of sampling the cervix.Objectives. To explore women’s attitudes to self-collection of samples for cervical screening in a low-resource setting in South Africa (SA).Methods. Mixed methods were used to meet the study objectives. We recruited women aged 30 - 65 years into a study in Cape Town, SA, to participate in a cross-sectional survey. All women collected a vaginal self-sample, and underwent visual inspection with acetic acid, colposcopy, and collection of cervical samples and appropriate histology specimens by a doctor. Women had a quantitative questionnairebased exit interview. A subset of these women participated in focus group discussions (FGDs).Results. A total of 822 women answered the exit survey questionnaire and 41 women participated in the FGDs. Most women from the survey had a positive perception of self-sampling, with 93.6% of the women reporting not feeling embarrassed and 89.4% reporting experiencing no discomfort at all when taking a self-sample. This was corroborated by the FGD participants, who found self-sampling easier, more comfortable and less embarrassing than clinician sampling. However, many women (64.7%) felt more confident when the sample was taken by a clinician, despite having a positive attitude towards self-sampling. In most cases this was because they thought that the clinician would take a better sample, as explained by the FGD participants. Although 93.9% of the women were willing to collect a selfsample, the women in the FGDs expressed a preference for doing so at the health facility rather than at home. There were many reasons for this, including the cost of returning to the clinic with the sample.Conclusions. Attitudes regarding self-sample collection were positive in this study population. Participants were willing to perform selfsampling, but expressed concerns regarding the quality of the specimen and the financial implications of returning to the clinic with it. Pilot implementation studies will be useful before this method of sampling is adopted and integrated into screening programmes
The HealtheSteps™ lifestyle prescription program to improve physical activity and modifiable risk factors for chronic disease: a pragmatic randomized controlled trial.
BACKGROUND: Our objective was to determine the influence of the HealtheSteps™ lifestyle prescription program on physical activity and modifiable risk factors for chronic disease in individuals at risk.
METHODS: One hundred eighteen participants were recruited from 5 sites in Southwestern Ontario, Canada and randomized to either the intervention (HealtheSteps™ program, n = 59) or a wait-list control group (n = 59). The study comprised three phases: an Active Phase (0 to 6 months) consisted of bi-monthly in-person lifestyle coaching with access to a suite of eHealth technology supports (Heathesteps app, telephone coaching and a private HealtheSteps™ social network) followed by a Minimally-Supported Phase I (6 to 12 months), in which in-person coaching was removed, but participants still had access to the full suite of eHealth technology supports. In the final stage, Minimally-Supported Phase II (12 to 18 months), access to the eHealth technology supports was restricted to the HealtheSteps™ app. Assessments were conducted at baseline, 6, 12 and 18 months. The study primary outcome was the 6-month change in average number of steps per day. Secondary outcomes included: self-reported physical activity and sedentary time; self-reported eating habits; weight and body composition measures; blood pressure and health-related quality of life. Data from all participants were analyzed using an intent-to-treat approach. We applied mixed effects models for repeated measurements and adjusted for age, sex, and site in the statistical analyses.
RESULTS: Participants in HealtheSteps™ increased step counts (between-group [95% confidence interval]: 3132 [1969 to 4294], p \u3c 0.001), decreased their sitting time (- 0.08 [- 0.16 to - 0.006], p = 0.03), and improved their overall healthful eating (- 1.5 [- 2.42 to - 0.58], p = 0.002) to a greater extent compared to control at 6 months. Furthermore, exploratory results showed that these individuals maintained these outcomes 12 months later, after a minimally-supported phase; and retained improvements in sedentary time and improved healthful eating after 18 months. No differences in self-reported physical activity, health-related quality of life, weight, waist circumference or blood pressure were observed between groups at 6 months.
CONCLUSIONS: Our findings suggest that HealtheSteps™ is effective at increasing physical activity (i.e., step counts per day), decreasing weekday sitting time, and improving healthful eating in adults at increased risk for chronic disease after 6 months; however, we did not see change in other risk factors. Nonetheless, the maintenance of these behaviours with minimal support after 12 and even 18 months indicates the promise of HealtheSteps™ for long-term sustainability.
TRIAL REGISTRATION: The trial was registered on April 6, 2015 with ClinicalTrials.gov (identifier: NCT02413385 )
Synthesis of a Graphene-Encapsulated Fe 3 C/Fe Catalyst Supported on Sporopollenin Exine Capsules and Its Use for the Reverse Water–Gas Shift Reaction
Bioderived materials have emerged as sustainable catalyst supports for several heterogeneous reactions owing to their naturally occurring hierarchal pore size distribution, high surface area, and thermal and chemical stability. We utilize sporopollenin exine capsules (SpECs), a carbon-rich byproduct of pollen grains, composed primarily of polymerized and cross-linked lipids, to synthesize carbon-encapsulated iron nanoparticles via evaporative precipitation and pyrolytic treatments. The composition and morphology of the macroparticles were influenced by the precursor iron acetate concentration. Most significantly, the formation of crystalline phases (Fe3C, α-Fe, and graphite) detected via X-ray diffraction spectroscopy showed a critical dependence on iron loading. Significantly, the characteristic morphology and structure of the SpECs were largely preserved after high-temperature pyrolysis. Analysis of Brunauer–Emmett–Teller surface area, the D and G bands from Raman spectroscopy, and the relative ratio of the C═C to C–C bonding from high-resolution X-ray photoelectron spectroscopy suggests that porosity, surface area, and degree of graphitization were easily tuned by varying the Fe loading. A mechanism for the formation of crystalline phases and meso-porosity during the pyrolysis process is also proposed. SpEC-Fe10% proved to be highly active and selective for the reverse water–gas shift reaction at high temperatures (>600 °C)
