Acceptability and Feasibility of a Meaning-Based Intervention for Patients With Advanced Cancer and Their Spouses A Pilot Study

Background: Constructing meaning in cancer leads to improved psychosocial outcomes for patients and survivors. Aim: We tested the feasibility and preliminary efficacy of a meaning-based intervention for couples. Design: The single-arm pilot study tested a 4-session, tailored, activities-based couple’s intervention. Setting/Participants: Twelve adults with incurable cancer and their partners participated either in a university office or at the couple’s home. Results: The study showed good feasibility. One of the two patients depressed at baseline was no longer depressed at postintervention. Patients’ threat appraisals decreased and transcendence increased. In partners, depression, anxiety, and challenge appraisal decreased; threat and secondary appraisals and peace with illness increased. Conclusions: Our findings suggest feasibility and efficacy, and further research and continued evaluation of this intervention are warranted

The impact of seasonal variability in wildlife populations on the predicted spread of foot and mouth disease

Modeling potential disease spread in wildlife populations is important for predicting, responding to and recovering from a foreign animal disease incursion such as foot and mouth disease (FMD). We conducted a series of simulation experiments to determine how seasonal estimates of the spatial distribution of white-tailed deer impact the predicted magnitude and distribution of potential FMD outbreaks. Outbreaks were simulated in a study area comprising two distinct ecoregions in South Texas, USA, using a susceptible-latent-infectious-resistant geographic automata model (Sirca). Seasonal deer distributions were estimated by spatial autoregressive lag models and the normalized difference vegetation index. Significant (P < 0.0001) differences in both the median predicted number of deer infected and number of herds infected were found both between seasons and between ecoregions. Larger outbreaks occurred in winter within the higher deer-density ecoregion, whereas larger outbreaks occurred in summer and fall within the lower deer-density ecoregion. Results of this simulation study suggest that the outcome of an FMD incursion in a population of wildlife would depend on the density of the population infected and when during the year the incursion occurs. It is likely that such effects would be seen for FMD incursions in other regions and countries, and for other diseases, in cases in which a potential wildlife reservoir exists. Study findings indicate that the design of a mitigation strategy needs to take into account population and seasonal characteristics

M87: A Misaligned BL LAC?

The nuclear region of M87 was observed with the Faint Object Spectrograph (FOS) on the Hubble Space Telescope (HST) at 6 epochs, spanning 18 months, after the HST image quality was improved with the deployment of the corrective optics (COSTAR) in December 1993. From the FOS target acquisition data, we have established that the flux from the optical nucleus of M87 varies by a factor ~2 on time scales of ~2.5 months and by as much as 25% over 3 weeks, and remains unchanged (<= 2.5%) on time scales of ~1 day. The changes occur in an unresolved central region <= 5 pc in diameter, with the physical size of the emitting region limited by the observed time scales to a few hundred gravitational radii. The featureless continuum spectrum becomes bluer as it brightens while emission lines remain unchanged. This variability combined with the observations of the continuum spectral shape, strong relativistic boosting and the detection of significant superluminal motions in the jet, strongly suggest that M87 belongs to the class of BL Lac objects but is viewed at an angle too large to reveal the classical BL Lac properties.Comment: 12 pages, 3 Postscript figure

Families in Transition: The Lived Experience of Parenting a Transgender Child

This qualitative study explored parent’s experiences of their child undergoing gender transition. Data analysis yielded themes that begin to identify the complex nature and struggles parents face as they encounter the emotional and physical aspects of this transition. The focus is on the context of the family rather than the broader social context of school or community. The central question is: “What is the experience of parenting a transgender child?

Microtubules in Bacteria: Ancient Tubulins Build a Five-Protofilament Homolog of the Eukaryotic Cytoskeleton

Microtubules play crucial roles in cytokinesis, transport, and motility, and are therefore superb targets for anti-cancer drugs. All tubulins evolved from a common ancestor they share with the distantly related bacterial cell division protein FtsZ, but while eukaryotic tubulins evolved into highly conserved microtubule-forming heterodimers, bacterial FtsZ presumably continued to function as single homopolymeric protofilaments as it does today. Microtubules have not previously been found in bacteria, and we lack insight into their evolution from the tubulin/FtsZ ancestor. Using electron cryomicroscopy, here we show that the tubulin homologs BtubA and BtubB form microtubules in bacteria and suggest these be referred to as “bacterial microtubules” (bMTs). bMTs share important features with their eukaryotic counterparts, such as straight protofilaments and similar protofilament interactions. bMTs are composed of only five protofilaments, however, instead of the 13 typical in eukaryotes. These and other results suggest that rather than being derived from modern eukaryotic tubulin, BtubA and BtubB arose from early tubulin intermediates that formed small microtubules. Since we show that bacterial microtubules can be produced in abundance in vitro without chaperones, they should be useful tools for tubulin research and drug screening

Randomized Controlled Pilot Trial of Mindfulness-Based Stress Reduction Compared to Psychoeducational Support for Persistently Fatigued Breast and Colorectal Cancer Survivors

Purpose Cancer-related fatigue (CRF) is a disruptive symptom for many survivors. Despite promising evidence for efficacy of Mindfulness-Based Stress Reduction (MBSR) in reducing CRF, no trials comparing it to an active comparator for fatigued survivors have been published. The purpose of this trial was to compare MBSR to psychoeducation for CRF and associated symptoms. Methods Breast (n=60) and colorectal (n=11) cancer survivors (stage 0–III) with clinically significant CRF after completing chemotherapy and/or radiation therapy an average of 28 months prior to enrollment were randomized to MBSR or psychoeducation/support groups (PES). MBSR focused on mindfulness training; PES focused on CRF self-management. Outcomes included CRF interference (primary), CRF severity and global improvement, vitality, depression, anxiety, sleep disturbance, and pain. Outcomes were assessed at baseline (T1), post-intervention (T2), and 6-month follow-up (T3) using intent-to-treat analysis. Results Between-group differences in CRF interference were not significant at any time point; however, there was a trend favoring MBSR (d=−0.46, p=0.073) at T2. MBSR participants reported significantly greater improvement in vitality (d=0.53, p=0.003) and were more likely to report CRF as moderately-to-completely improved compared to the PES group (χ2 (1)=4.1765, p=0.041) at T2. MBSR participants also reported significantly greater reductions in pain at T2 (d=0.53, p=0.014). In addition, both MBSR and PES produced moderate-to-large and significant within-group improvements in all fatigue outcomes, depression, anxiety, and sleep at T2 and T3 compared to T1. Conclusion MBSR and PES appear efficacious for CRF and related symptoms. Larger trials including a usual care arm are warranted

The state of the Martian climate

60°N was +2.0°C, relative to the 1981–2010 average value (Fig. 5.1). This marks a new high for the record. The average annual surface air temperature (SAT) anomaly for 2016 for land stations north of starting in 1900, and is a significant increase over the previous highest value of +1.2°C, which was observed in 2007, 2011, and 2015. Average global annual temperatures also showed record values in 2015 and 2016. Currently, the Arctic is warming at more than twice the rate of lower latitudes

Trends in Depression and Antidepressant Prescribing in Children and Adolescents: A Cohort Study in The Health Improvement Network (THIN)

In 2003, the Committee on Safety of Medicines (CSM) advised against treatment with selective serotonin reuptake inhibitors (SSRIs) other than fluoxetine in children, due to a possible increased risk of suicidal behaviour. This study examined the effects of this safety warning on general practitioners' depression diagnosing and prescription behaviour in children
