Purpose: Childhood cancer survivors are at increased lifetime risk of morbidity and mortality, but adherence to periodic surveillance is suboptimal. One of the reasons that adult survivors of childhood cancer do not complete the recommended surveillance is that their parents may not have disclosed their cancer history to them. We sought to identify key barriers and enablers to talking to children about their cancer history.

Objective: The pressure pain threshold is commonly employed to assess pain in various conditions. Despite its widespread use, the measurement of pressure pain thresholds is not consistently described across studies. Therefore, this review aimed to systematically examine the evidence regarding the assessment of pressure pain thresholds in patients with low back pain, including the protocols and body sites employed.

Bone and dental lesions have been documented in various deer species globally, affecting the efficiency of ingestion and digestion, consequently influencing their general health and leading to a decline in survival and reproductive performance. The present study aimed to characterize bone and dental lesions in the dry skulls of individual deer, estimate the prevalence of these lesions, and assess potential risk factors associated with the development of bone and dental alterations. This study assessed bone and dental lesions in 180 dry skulls of eleven neotropical deer species, originating from both captivity and wildlife conditions, through direct visual inspection.

Specialty coffee beans are those produced, processed, and characterized following the highest quality standards, toward delivering a superior final product. Environmental, climatic, genetic, and processing factors greatly influence the green beans' chemical profile, which reflects on the quality and pricing. The present study focuses on the assessment of eight major health-beneficial bioactive compounds in green coffee beans aiming to underscore the influence of the geographical origin and post-harvesting processing on the quality of the final beverage.

Objective: To explore the available knowledge on the application of biopsychosocial model (BPS) in patients with chronic low back pain (CLBP).

Methods: A scoping review, including 32 papers that used a BPS to manage adult patients with CLBP, published in any language. Six different databases were searched.

Background: The prevalence of moderate to high levels of fear of cancer recurrence (FCR) in cancer survivors may vary from 22% to 87%, although most are not usually referred to psychosocial support. The After Cancer Treatment Transition (ACTT) clinic in Women's College Hospital (Toronto) provides follow-up care to cancer survivors but in a sample of 2893 patients seen April 2019 to March 2022, only 1.5% were referred to a social worker for psychosocial needs.

Background: Childhood-onset Systemic Lupus Erythematosus (cSLE) is an autoimmune disease associated with fatigue, mood symptoms, and pain. Fortunately, these symptoms are potentially modifiable with psychological intervention such as cognitive-behavioral therapy (CBT). The Treatment and Education Approach for Childhood-onset Lupus (TEACH) program is a CBT intervention developed to target these symptoms for adolescents and young adults with cSLE.

COVID-19 changed the context for Information and Communication Technology (ICT) use globally. With face-to-face practice restricted, almost all communication with clients shifted to ICTs. Starting in April 2019, we conducted semi-structured interviews with social workers from four agencies serving diverse populations in a large urban centre, with the aim of exploring social workers' informal ICT use with clients.

Objective: The aim of this study was to analyze the reproducibility of a protocol using the maximal isometric strength test of the trunk in elderly women aged above 60 years, without low back pain.

Methods: Twenty-one physically inactive elderly women, who had not engaged in any activity or exercise program in the past three months, participated in the cross-sectional study that consisted of two days of evaluations for the maximal isometric strength of the extensor and flexor muscles of the trunk, with a 48 h interval between the sessions. A platform with fixed seating was used, which allowed the fixation of the hip and lower limbs, with a load cell connected to a linear encoder.

The effects of hydroethanolic extract of Yacon leaves (HEYL) on antioxidant, glycemic, and inflammatory biomarkers were tested in diabetic rats. Outcome parameters included glucose, insulin, interleukin-6 (IL-6), and hydrophilic antioxidant capacity (HAC) in serum and IL-6, HAC, malondialdehyde (MDA), superoxide dismutase (SOD), catalase (CAT), and glutathione peroxidase (GPx) in soleus. The rats (10/group) were divided as follows: C, controls; C + Y, HEYL treated; DM, diabetic controls; and DM + Y, diabetic rats treated with HEYL.

Aims: Myocardial perfusion scintigraphy (MPS) is an important diagnostic tool in the management of patients with suspected coronary artery disease (CAD). However, the presence of mild-moderate perfusion defects can be challenging and may lead to unnecessary cardiac catheterization. Coronary computed tomography angiography (CCTA) is a method with excellent accuracy in the evaluation of CAD, but its role in this setting of patients has not been fully defined.

Background: The absence of nocturnal blood pressure dipping (ND) identified by 24-h ambulatory blood pressure monitoring (ABPM) correlates with a worse cardiovascular prognosis. The renin-angiotensin system influences blood pressure levels and the occurrence of target organ damage (TOD). Thus, the aim of this study was to correlate the angiotensin-converting enzyme gene (ACE) insertion/deletion (I/D) polymorphism with the 24-h blood pressure profile and TOD in hypertensive individuals.

Different brain areas seem to be involved in the cardiovascular responses to stress. The medial amygdala (MeA) has been shown to participate in cardiovascular control, and acute stress activates the MeA to a greater extent than any of the other amygdaloid structures. It has been demonstrated that the brain histaminergic system may be involved in behavioral, autonomic and neuroendocrine responses to stressful situations.

We previously showed that a single intrapleural dose of an adenoviral vector expressing interferon-beta (Ad.IFN-beta) in patients with malignant pleural mesothelioma (MPM) or malignant pleural effusions (MPE) resulted in gene transfer, humoral antitumor immune responses, and anecdotal clinical responses manifested by modified Response Evaluation Criteria in Solid Tumors (RECIST) disease stability in 3 of 10 patients at 2 months and an additional patient with significant metabolic response on positron emission tomography (PET) imaging. This phase I trial was conducted to determine whether using two doses of Ad.

Lung cancer is the leading cause of cancer deaths in the United States. Current therapies are inadequate. Histone deacetylase inhibitors (HDACi) are a recently developed class of anticancer agents that cause increased acetylation of core histones and nonhistone proteins leading to modulation of gene expression and protein activity involved in cancer cell growth and survival pathways.
