An optimal amount of labile zinc (Zn ) is essential for proliferation of human cells, where Zn levels that are too high or too low cause cell cycle exit. Tumors of the breast have been characterized by high levels of total Zn . Given the role of Zn in proliferation of human cells and elevation of zinc in breast cancer tumors, we examined the concentration of total and labile Zn across a panel of 5 breast cancer cell lines, compared to the normal MCF10A cell line.

Objective: Previous research has shown that experiencing an acute cardiac event, such as a myocardial infarction (MI), can lead to lifestyle changes. This study aimed to explore the potential of a MI as a 'teachable moment' (TM) for positive lifestyle changes and to identify psychosocial sensemaking processes that facilitate or hinder the presence of a TM.

Method: We conducted semi-structured interviews with 14 patients who suffered their first MI and were hospitalized in a larger Dutch city.

Objectives: Envisioning one's (non)smoking future may make (un)desired future identities more accessible, salient, and personally relevant and facilitate smoking cessation. The current study assessed whether a future-self intervention can weaken smoker self-identity and expected identity loss when quitting smoking, and strengthen quitter- and nonsmoker self-identity, while accounting for personal factors-socioeconomic position, nicotine dependence, consideration of future consequences, and clarity of the envisioned future-self. Additionally, it examined the association between smoking-related identity and quitting intention and behavior.

Identity, or 'who I am', is important for smoking behaviour. Identity constructs (parts of a person's identity) are typically examined as separate entities, but emerging evidence suggests that the multifaceted nature of identity is relevant in the context of smoking. This cross-sectional study examined how smoking-related self- and group-identity constructs cluster within adult daily smokers (N = 231), whether classes of smokers can be distinguished based on clusters of identity constructs, and which factors explain class membership.

Introduction: Smoking and insufficient physical activity (PA), independently but especially in conjunction, often lead to disease and (premature) death. For this reason, there is need for effective smoking cessation and PA-increasing interventions. Identity-related interventions which aim to influence how people view themselves offer promising prospects, but an overview of the existing evidence is needed first.

Better conceptually-driven research is necessary to learn more about 1) the characteristics of life events as teachable moments (TMs) and 2) the potential of life events to evoke lifestyle change intention (LCI). This study aimed to develop and validate two scales for the purposes of TM research in the context of cardiovascular disease (CVD): the and scales. After the initial development of items based on a theoretical framework and literature search, six experts rated the content validity of both scales as sufficient.

Background: Adolescents and young adults frequently post alcohol-related content (ie, alcoholposts) on social media. This is problematic because both social norms theory and social learning theory suggest that viewing alcoholposts of peers could increase drinking behavior. It is therefore paramount to understand the effects of exposure to alcoholposts on viewers.

When lifestyle changes are needed, life events or crises such as COVID-19 may function as "teachable moments". This study aimed to explore whether the pandemic can provoke a teachable moment regarding lifestyle change in cardiovascular disease patients. In this cross-sectional survey study, 830 cardiovascular disease patients reported their intentions to change lifestyle, instigated by the corona crisis, together with risk perception, affective impact, and changed self-concept, based on a "teachable moments" framework.

Purpose: This study focusses on identifying values and preferences of patients, caregivers and healthcare professionals who have dealt with lower limb amputation for no-option chronic limb threatening ischemia. No-option chronic limb threatening ischemia is defined as limb ischemia for which no treatment options exist and where lower limb amputation is necessary in the short term. The values and preferences identified in this study can help improve decision-making processes.

Healthcare professionals can play a significant role in the prevention of lifestyle-related diseases. Yet there is still relatively little attention to lifestyle counseling, partly because of limited available time and doubts about its effectiveness. During so-called 'teachable moments', patients may be more receptive towards lifestyle advices and more motivated to change their lifestyle.

Article Synopsis
  • NCAM1 (CD56) is found in about 20% of acute myeloid leukemia (AML) patients and is used as a marker for minimal residual disease, but its specific function in AML is not fully understood.
  • The study reveals that NCAM1 is crucial for cell survival and stress resistance in AML, as its disruption leads to increased cell death and makes leukemic cells more sensitive to treatments.
  • Additionally, high NCAM1 expression correlates with active MAPK signaling and plays a role in maintaining leukemia stem cells, suggesting that targeting the MEK1/2 pathway could enhance chemotherapy efficacy in NCAM1-positive AML patients.

Background: Support staff of adults with intellectual disability (ID) play an important role in promoting independence in home and community settings. However, little is known about the types of behaviours staff should use to promote independence and instruments that assess such behaviour do not yet exist. The aim of this study was therefore to develop and initially validate a reliable questionnaire that measures the degree to which support staff display behaviours that promote independence in people with ID.

The pharmaceutical valsartan is classified as a trace organic compound and is released into wastewater from human consumption. Trace organic compounds are not completely removed during conventional wastewater treatment. In order to prevent their release into the aquatic environment, advanced wastewater treatment technologies such as ozonation are currently implemented.

Young people frequently display alcohol-related posts ("alcoholposts") on social networking sites such as Facebook and Instagram. Although evidence exists that such posts may be linked with increases in alcohol consumption, hardly any studies have focused on the content of such posts. This study addresses this gap by applying and extending the alcoholpost-typology previously proposed by Hendriks, Gebhardt, and van den Putte.

Background: Recent developments in drug use patterns call for an investigation of current party-drug use and associated problems among college students, who appear to be an important target population for harm reduction interventions.

Objectives: In addition to reporting on party-drug use prevalence, we investigated whether initial use and continuation of party-drug use among students was associated with demographic, personality and psychosocial factors.

Methods: An online questionnaire was administered to 446 students from a Dutch university, inquiring about party-drug use, demographic characteristics, social norms and personality (big five, impulsiveness, aggression).
