Summary
Text messages can improve adherence to online smoking cessation programs. This study tested features like personalization and dynamic tailoring to optimize text message interventions for smokers seeking to quit.
Area of Science:
- Digital Health
- Behavioral Science
- Public Health
Background:
- Internet-based smoking cessation interventions have low engagement.
- Mobile devices and text messaging offer potential to improve adherence.
- Text messages can proactively encourage use of web-based cessation programs.
Purpose of the Study:
- To test features of text message interventions for smoking cessation adherence.
- To compare a web-based program with and without optimized text messaging for smoking abstinence.
Main Methods:
- Phase I: Factorial design to test personalization, integration, dynamic tailoring, and message intensity (N=860).
- Phase II: Randomized trial comparing web-based program alone vs. with optimized text messages (N=600).
- Primary outcome: Composite adherence metric; Secondary outcome: 30-day point prevalence abstinence.
Main Results:
- (Results not yet available as study is in progress)
Conclusions:
- Optimized text messaging interventions may enhance adherence and efficacy of internet-based smoking cessation programs.
- Further research is needed to confirm the impact of specific text message features on smoking cessation outcomes.

2.1K
Adrenergic agonists have diverse therapeutic uses across various medical conditions and emergencies.
Emergency and Intensive Care Unit (ICU) applications: Pressor agents increase blood pressure, heart rate, and contractility in shock and organ failure situations. Dopamine can induce vasodilation and stimulate adrenoceptors. Endogenous catecholamines are effective in treating cardiogenic shock. α2-agonists like clonidine can reverse anesthesia-induced hypertension.

Focusing involves centering a conversation on a message's critical elements or concepts. Focusing is valuable if the talk is vague or patients begin to repeat themselves. Sometimes, when patients are asked about their symptoms, they may go off-topic and try to tell their entire life story. Respectfully, the nurse should bring the conversation back into focus.
This therapeutic technique can also be used when a patient brings up pertinent information during a health-related conversation. The...

Managing Chronic Obstructive Pulmonary Disease (COPD) involves a multifaceted approach to reduce symptoms, prevent exacerbations, improve overall health status, and slow disease progression. Key strategies include lifestyle modifications, pharmacotherapy, supportive therapies, and, in some cases, surgery. Here is an overview of the primary COPD management strategies:

Adrenergic agonists can be classified based on their therapeutic uses and mechanisms of action. They serve various purposes in clinical applications.
Vasopressor or pressor agents: They increase blood pressure and function as cardiac stimulants. Examples include endogenous catecholamines (norepinephrine and dopamine) and synthetic agents (phenylephrine).
Bronchodilators: β2-agonists can relax bronchial muscles and widen airways. They are commonly used for treating obstructive pulmonary...
