Adaptive metabolic response towards a low oxygen environment is essential to maintain rapid tumour proliferation and progression. The vascular network that surrounds the tumour develops an intermittent hypoxic condition and stimulates hypoxia-inducing factors. Baeckea frutescens is used in traditional medicine and known to possess antibacterial and cytoprotective properties. In this study, the cytotoxic effect of B. frutescens leaves and branches extracts against hypoxic human breast cancer (MCF-7) was investigated.
The extracts were prepared using Soxhlet apparatus for ethanol and hexane extracts while the water extracts were freeze-dried. In vitro cytotoxic activities of B. frutescens extracts of various concentrations (20 to 160 μg/mL) at 24, 48, and 72 hours time points were studied using MTT in chemically induced hypoxic condition and in 3-dimensional in vitro cell culture system. An initial characterisation of B. frutescens extracts was carried out using Fourier-transform Infrared- Attenuated Total ons defines a new role of natural product that can be utilised as an effective agent that regulates metabolic reprogramming in breast cancer.
Adaptation of tumour cells to hypoxia significantly contributes to the aggressiveness and chemoresistance of different tumours. The identification of B. EPZ011989 frutescens and its possible role in eliminating breast cancer cells in hypoxic conditions defines a new role of natural product that can be utilised as an effective agent that regulates metabolic reprogramming in breast cancer.
Physical activity (PA) may play a key role in healthy aging and thus in promoting health-related quality of life (HRQoL). However, longitudinal studies on the association between PA and HRQoL are still scarce and have shown inconsistent results. In this study, we aimed to examine the longitudinal association between frequency of moderate PA and physical and mental HRQoL. Secondly, to assess the association between a 12-month change in frequency of moderate PA and HRQoL.
A 12-month longitudinal study was conducted in Spain, Greece, Croatia, the Netherlands, and the United Kingdom with 1614 participants (61.0% female; mean age = 79.8; SD = 5.2) included in the analyses. Two categories of the self-reported frequency of moderate PA including 1) 'regular frequency' and 2) 'low frequency' were classified, and four categories of the change in frequency of moderate PA between baseline and follow-up including 1) 'continued regular frequency', 2) 'decreased frequency', 3) 'continued low frequency' and 4) 'increasedaining or increasing to a regular frequency of PA are associated with maintaining or improving physical and mental HRQoL. Our findings support the development of health promotion and long-term care strategies to encourage older adults to maintain a regular frequency of PA to promote their HRQoL.

This study aimed to evaluate the feasibility, safety, and efficacy of postoperative adjuvant chemotherapy with docetaxel/cisplatin/S-1 (DCS) following S-1 therapy in patients with stage III gastric cancer after curative gastrectomy.
Patients with stage III gastric cancer who underwent D2 gastrectomy were enrolled. Adjuvant chemotherapy was initiated within 8 weeks of gastrectomy. The first cycle of chemotherapy consisted of S-1 monotherapy (day 1-14), followed by a 7-day rest period. Cycles 2 and 3 consisted of the following S-1 (day 1-14) administration, followed by a 14-day rest period, and an intravenous infusion of cisplatin and docetaxel on days 1 and 15. After two cycles, S-1 was administered for up to 1 year.
Thirty patients were enrolled between 2014 and 2017. Febrile neutropenia of grade 3 or higher was the most common hematological toxicity with 4 patients (13.3%). Other hematological toxicities of grade 3 or higher were as follows neutropenia in 3 (10.0%), leukopenia in 3 (10.0%), and anemia in 2 (6.7%) patients. Most frequent non-hematological toxicity of grade 3 was anorexia (n = 4, 13.3%) and general fatigue (n = 3, 10.0%); no grade 4 non-hematological toxicities were observed. Twenty-five patients (83.3%) completed two cycles of DCS treatment and 18 (60.0%) completed subsequent S-1 treatment for 1 year. The relative dose intensity of docetaxel and cisplatin was 0.86 and that of S-1 was 0.88.
The DCS regimen can be acceptable as an adjuvant chemotherapy and offers an effective postoperative treatment option for stage III gastric cancer patients.

Given high rates of mental health and substance challenges among youth and substantial system access barriers, system innovation is required. Integrated youth services (IYS) models aim to transform youth mental health and substance use services by creating integrative, collaborative models of care in youth-friendly settings. This study examines service provider perspectives on the key service components to include in IYS models.
A discrete choice experiment modeled service provider preferences for the service components of IYSs. The sample includes 388 service provider/agency leader participants (age 18+) from youth-serving organizations in Ontario. Importance scores and utility values were calculated for 12 attributes represented by four levels each. Latent class analysis identified subgroups of participants with different preferences.
The majority of participants were direct service providers working in larger organizations in the mental health and/or substance use sectors in large urban centers. Partected to facilitate development, implementation and scaling of IYS models. Hearing stakeholder perspectives, including those of service providers, youth, and caregivers, is essential to developing, effectively implementing, and scaling effective youth services.
Reduced falls and fall risks have been observed among older adults referred to the HOP-UP-PT (Home-based Older Persons Upstreaming Prevention-Physical Therapy) program. The purpose of this study was to describe outcomes of HOP-UP-PT program participants and then to compare these outcomes to non-participants.
Six Michigan senior centers referred adults ≥65 years who were at-risk for functional decline or falls. 144 participants (n = 72 per group) were randomized to either the experimental group (EG) or the control group (CG). Physical therapists (PTs) delivered physical, environmental, and health interventions to the EG over nine encounters (six in-person, three telerehabilitation) spanning seven months. The CG participants were told to continue their usual physical activity routines during the same time frame. Baseline and re-assessments were conducted at 0-, 3-, and 7-months in both groups. Descriptions and comparisons from each assessment encounter were analyzed.
Participants ages were EG = 76.6 (7.0)ll risk demonstrated a significant decrease in falls. A collaboration between PTs and community senior centers resulted in upstreaming care delivery that may reduce both the financial and personal burdens associated with falls in an older adult population.

Systemic manifestations and comorbidities are characteristics of chronic obstructive pulmonary disease (COPD) and are probably due to systemic inflammation. The histone methyltransferase SUV39H1 controls the Th1/Th2 balance. We previously reported that reduced SUV39H1 expression contributed to abnormal inflammation in COPD. Here, we aimed to determine whether impaired SUV39H1 expression in COPD patients associated with neutrophilic/eosinophilic inflammation responses and comorbidities.
A total of 213 COPD patients and 13 healthy controls were recruited from the Shuang Ho Hospital, Taipei Medical University. SUV39H1 levels in peripheral blood mononuclear cells (PBMCs) from 13 healthy and 30 COPD participants were measured by immunoblotting. We classified the patients into two groups based on low (fold change, FC < 0.5) and high SUV39H1 expression (FC ≥ 0.5) compared to normal controls. Clinical outcomes including neutrophil or eosinophil counts associated with SUV39H1-related inflammation were evaluatedxacerbation) in numbers of WBC and proportion of neutrophils, eosinophils or eosinophil/neutrophil. Finally, patients with high comorbidities had lower SUV39H1 levels in their PBMCs than did those with low comorbidities.
Blood neutrophil counts are associated with comorbidities in COPD patients. Impaired SUV39H1 expression in PBMCs from COPD patients are correlated with neutrophilic inflammation and comorbidities.

Timely presentation and diagnosis of cervical cancer (CC) are crucial to decrease its mortality especially in low- and middle-income countries like Palestine. This study aimed to evaluate the knowledge of Palestinian women about CC warning signs and determine the factors associated with good knowledge.
This was a national cross-sectional study conducted between July 2019 and March 2020 in Palestine. Stratified convenience sampling was used to recruit adult women from hospitals, primary healthcare centers, and public spaces of 11 governorates. A translated-into-Arabic version of the validated CC awareness measure (CeCAM) was used to assess women's knowledge of 12 CC warning signs.
Of 8086 approached, 7223 participants completed the CeCAM (response rate = 89.3%). A total of 7058 questionnaires were included in the analysis 2655 from the Gaza Strip and 4403 from the West Bank and Jerusalem (WBJ). The median age [interquartile range] for all participants was 34.0 [24.0, 42.0] years. Participants recruited from the WBJ were older, getting higher monthly income, and having more chronic diseases than those recruited from the Gaza Strip. The most frequently identified warning sign was 'vaginal bleeding after menopause' (n = 5028, 71.2%) followed by 'extreme generalized fatigue' (n = 4601, 65.2%) and 'unexplained weight loss' (n = 4578, 64.9%). Only 1934 participants (27.4%) demonstrated good knowledge of CC warning signs. Participants from the Gaza Strip were slightlymore likely than participants from the WBJ to have a good level of knowledge. Factors associated with having good knowledge included having a bachelor or postgraduate degree, being married, divorced, or widowed as well as knowing someone with cancer.
The overall awareness of CC warning signs was low. Educational interventions are needed to increase Palestinian women's awareness of CC warning signs.
