Using telehealth to support lifestyle changes in cancer treatment: this article details the advantages and obstacles encountered. learn more Two recent telehealth lifestyle interventions, GO-EXCAP and weSurvive, are highlighted as case studies for underserved populations, including older adults and rural cancer survivors, and practical implementation strategies are presented for future endeavors. Telehealth's innovative application in lifestyle interventions for cancer survivors offers great promise in lessening the overall cancer burden.
Intermittent fasting involves limiting food consumption during designated periods, such as specific hours, days, religious observances, or circumstances with clinical significance. The mechanisms of metabolic and circadian rhythm underlying the purported benefits of intermittent fasting for those with cancer are presented. Published cancer studies, spanning epidemiological, preclinical, and clinical investigations from January 2020 to August 2022, are reviewed and avenues for future research are discussed. The use of intermittent fasting among cancer patients raises a serious concern regarding the frequent caloric restriction that fasting often entails, placing patients already vulnerable to malnutrition, cachexia, or sarcopenia in a compromised state. While clinical trials haven't yet furnished enough evidence to endorse intermittent fasting in standard medical care, this overview might prove helpful for patients, their support systems, and healthcare professionals who are researching intermittent fasting as part of their cancer treatment strategies for enhanced outcomes and symptom alleviation.
The life-threatening complication of cachexia is found in up to 80% of patients diagnosed with advanced cancer. Skeletal muscle wasting and unintended weight loss are key features of cachexia, a systemic consequence of cancer. Cancer-related mortality is exacerbated by cachexia, which compromises cancer treatment tolerance and diminishes quality of life. learn more Effective treatments for cancer cachexia are sadly absent, despite the numerous decades dedicated to research efforts. The expanding utilization of high-throughput omics technologies is significantly impacting various fields, including cancer cachexia, to facilitate the discovery of disease biology and the selection of targeted therapies. Selected omics technologies are presented in this paper, focusing on their utility in evaluating skeletal muscle alterations during cancer cachexia. A comprehensive analysis of omics-derived molecular profiles was performed to identify the muscle loss patterns in cancer cachexia, differentiating it from other muscle-wasting conditions, further delineating it from treatment-related muscle changes, and uncovering disease-severity-dependent mechanisms during cancer cachexia progression from its initial to its advanced stage.
The Biology of Aging fourth-year course, during the pandemic, was effectively redesigned with a comprehensive flipped classroom strategy, leading to heightened student engagement levels. Students' ability to connect through Zoom facilitated meaningful in-class learning experiences, fostering engagement and knowledge acquisition. The incorporation of pre-recorded lectures as supplemental learning materials, coupled with the use of Brightspace forums for post-class discussion, further augmented the educational experience. Student satisfaction and the educational experience were both enhanced by these changes. Adopting an active, student-centric approach to learning and facilitation created a dynamic and well-received teaching environment. The catch was that students had to produce weekly content; many course members considered this a substantial yet manageable chore. learn more These format alterations can be adapted for employment in other online educational courses.
While protein consumption demonstrably boosts body temperature and energy expenditure, the underlying biological mechanism is still not entirely understood. Protein consumption concurrently and strongly incites the secretion of glucagon-like peptide-1 (GLP-1). Using rodents, we assessed the impact of GLP-1 on the thermic effects of dietary proteins. This involved measuring rectal temperature and energy expenditure, and altering GLP-1 signaling. Thermocouple thermometers were employed to measure the rectal temperatures of rats or mice that had fasted for four or five hours, both before and after oral nutrient administration. Rats were also observed for oxygen consumption levels following oral protein intake. Analysis of rectal temperature in rats, after refeeding, highlighted a rise in core body temperature, with the oral administration of protein generating a greater thermic effect compared to carbohydrates or lipids. Of the five dietary proteins—casein, whey, rice, egg, and soy—soy protein exhibited the greatest thermic effect. By demonstrating an elevation in oxygen consumption, the thermic effect of soy protein was highlighted. Researchers employed a nonselective -adrenergic receptor blocking agent and a thermal camera to determine whether brown adipose tissue played a role in the rise of rectal temperature following soy protein ingestion. In addition, the thermic impact of soy protein was completely suppressed by blocking and removing the GLP-1 receptor, however, it was intensified through raising intact GLP-1 levels by inhibiting dipeptidyl peptidase-4. The thermic effects of dietary protein in rats and mice are demonstrably contingent on GLP-1 signaling, as these results show, broadening the metabolic actions of GLP-1, originating from nutrient intake, to now encompass the thermic response induced by protein.
Among individuals afflicted by alcohol use disorder (AUD), a considerable proportion encounter persistent sleep impairments, for which existing medication options remain scarce. We aimed to critically evaluate cannabidiol's (CBD) capacity to treat sleep difficulties resulting from alcohol use disorder. The notable side effects and the potential for abuse linked to existing medications for AUD-induced sleep disturbance ultimately diminish their clinical usefulness. CBD's impact on the endocannabinoid system, and its generally favorable safety profile, have generated considerable enthusiasm for its potential use as a therapeutic agent for a variety of medical conditions. Research across preclinical and clinical settings suggests the possibility of CBD in restoring the natural sleep-wake cycle and improving sleep quality for individuals affected by Alcohol Use Disorder. Based on its pharmacological properties and the available scientific literature, predominantly from preclinical studies and indirect observations, CBD emerges as a potential remedy for sleep disruption caused by alcohol consumption. Comprehensive randomized controlled trials are needed to determine its potential efficacy in managing this intricate element of AUD.
The study investigated whether the effect of internet engagement on the mental well-being of older Chinese adults was contingent on the strength of their intergenerational relationships and if this moderating influence differed across various age groups.
Survey data was collected from a group of 1162 individuals, all of whom were 60 years old or older. For the evaluation of loneliness, the Chinese version of the De Jong Gierveld Loneliness Scale, along with the Satisfaction with Life Scale (SWLS) to measure life satisfaction, and the Intergenerational Relationship Quality Scale for Aging Chinese Parents (IRQS-AP) to assess intergenerational relationship quality are used. To assess the moderating effect of intergenerational relationships on the relationship between internet engagement and mental well-being, two-stage least squares regression with interaction terms was employed in different age cohorts.
Older adults, specifically the young-old, displayed a statistically significant connection between greater internet engagement and both higher life satisfaction and less loneliness. Furthermore, a heightened positive association emerged between internet participation and mental health amongst older adults experiencing conflicted or disconnected family ties.
Encouraging internet usage in older adults to shrink the digital divide, creating a solid internet infrastructure, providing low-cost internet services, especially for the elderly with complex or distant family ties, and the oldest old.

This investigation scrutinized the ability of microorganisms, isolated from oil-contaminated soil, to degrade low-density polyethylene (LDPE) film, further analyzing the morphological and chemical composition of the treated LDPE film after the period of biodegradation. Utilizing standardized bacterial strains, isolated from oil-contaminated soil, pretreated LDPE films were degraded within mineral salt media. Incubation in a shaking incubator at 37°C for 78 days was followed by quantitative and qualitative analysis of the degraded LDPE films, using scanning electron microscopy (SEM) images and energy-dispersive X-ray (EDX) spectrometry. Isolates A32 and BTT4, alongside other bacterial isolates, were found to possess remarkable LDPE film degradation capabilities, resulting in weight reductions of 7180% and 8972% respectively. This was confirmed by 16S rRNA sequencing. The EDX measurements indicated a substantial reduction in carbon and nitrogen levels (238% and 449%, respectively) in LDPE film exposed to A32 compared to the control.
