Effectiveness

How Cardura Affects Patients

Doxazosin is used to lower blood pressure and treat symptoms of an enlarged prostate. Taking this drug can cause dizziness or lightheadedness, especially when you first start taking it or if there are long breaks between doses. It is important to slowly increase the dose, beginning with the lowest (1 mg). Doxazosin can also have positive effects on cholesterol levels, reducing LDL and triglycerides and increasing HDL. Rarely, doxazosin may cause priapism, a painful condition of long-lasting erections that can eventually lead to impotence. If you suspect you have priapism,

How Cardura works in the body

Doxazosin works by blocking receptors in blood vessels, reducing the amount of pressure in your blood. It also relaxes the muscles around your prostate and bladder neck, helping to reduce symptoms of Benign Prostatic Hyperplasia (BPH). Although it can help with BPH, there is a risk of heart failure associated with doxazosin use.

Cardura for High Blood Pressure

I was treated for prostate cancer in 1996. After treatment I experienced urination frequency and voiding problems. I have been on 4 to 8 milligrams of Cardura per day ever since. I have not noticed any severe side effects, but am more tired than I think I should be.

BPCARE Intervention for High Blood Pressure

18+
All Sexes
San Diego, CA

The goal of this randomized clinical trial is to determine whether a community health worker-delivered, multi-component behavioral intervention can improve antihypertensive medication adherence and blood pressure control among adult refugees with hypertension who are prescribed antihypertensive medications. The main questions it aims to answer are: 1. Does participation in the BPCARE intervention improve antihypertensive medication adherence compared to enhanced usual care? 2. Does participation in the BPCARE intervention improve blood pressure control and persistence over time compared to enhanced usual care? Researchers will compare participants randomized to the BPCARE intervention to those receiving enhanced usual care (hypertension information and a home blood pressure monitor) to determine the effects on medication adherence, blood pressure control, and persistence. Participants will: * Be randomly assigned to either the BPCARE intervention or enhanced usual care * Receive hypertension education and a home blood pressure monitor * Participate in community health worker-delivered sessions that include hypertension and medication education, motivational interviewing, problem-solving, and action planning (intervention arm only) * Complete questionnaires assessing medication adherence and related psychosocial factors * Have blood pressure monitored using connected home blood pressure devices * Complete pill counts to assess medication adherence over a nine-month follow-up period

Fayetteville, AR

In this study, the investigators are testing the effectiveness and implementation of the Community Health Workers (CHW)-delivered PILI Pasifika Program (PPP) Standard Facilitation or Enhanced Facilitation across 3 regions, the U.S. Affiliated Pacific Islands (USAPI), the continental U.S., and Hawai'i, among 600 Native Hawaiian and Pacific Islander (NHPI) participants in two settings, (clinical and non-clinical) over a 3-year period. The PPP is a 3-month lifestyle intervention that includes a Social Determinants of Health (SDOH) component and was NHPI-adapted from the Diabetes Prevention Program's Lifestyle Program, renamed to the PILI Lifestyle Program (PLP), which demonstrated effectiveness in improving weight, blood pressure, physical activity, and diet among NHPIs. The PPP consists of 8 lifestyle lessons and 4 SDOH activities delivered over a 3-month period. The investigators will conduct an effectiveness-implementation hybrid type 2 trial using a 3 (Region) x 2 (Setting) x 2 (Delivery Mode) factorial design. The long-term objective of this study is threefold: 1. To conduct an effectiveness-implementation hybrid 2 trial to test the effects of the PPP implementation strategies across different settings and modes of delivery among 600 NHPIs at risk for cardiometabolic-related conditions using an NHPI-approved and adapted evaluation framework. The investigators will also assess and compare the cost-effectiveness of the CHW-delivered PPP-Standard Facilitation and PPP-Enhanced Facilitation to support long-term sustainability. 2. To conduct a longitudinal Social Determinants of Health (SDOH) survey embedded within the trial to examine the reliability and validity of indices from 5 adapted SDOH instruments and to assess the associations between SDOH variables and chronic disease risk among NHPIs. 3. To implement and evaluate the contextually-based CHW training program on PPP delivery.

Dietary Interventions for Hypertension

18+
All Sexes
Birmingham, AL

Natriuretic peptides (NPs) are hormones produced by the heart and play an important role in maintaining cardiovascular health and have favorable metabolic benefits. Low NP levels are associated with an increased likelihood of the development of cardiometabolic diseases like diabetes and hypertension. NP levels are known to be highly heritable, with up to half of the differences in NP levels being explained by genetics. The investigators aim to describe the genetic architecture of NPs by examining the genetic variants associated with NPs, and generate and validate a polygenic score (PGS) for NPs. The investigators will use this NP PGS to examine the association of genetically determined NP levels with cardiometabolic and cardiovascular outcomes. The investigators will conduct a genotype-guided physiological clinical trial that aims to assess the genetic factors affecting NP levels and their impact on blood pressure and NP response to saline infusion, high-salt diet, and low-salt diet. These findings will help support personal medicine approaches to lower the increasing burden of hypertension in the United States.

Optilume vs Rezum for Enlarged Prostate

18+
Male
Montréal, Canada

Lower urinary symptoms (LUTS) affect older men and their frequency and severity increase with age. According to Berry et al., the histological diagnosis of benign prostatic hyperplasia (BPH) increases from 25% in the group age between 40 to 49 years to 80% in the group age between 70 to 79 years (1). However, this hyperplasia can lead to a bladder outlet obstruction (BOO) secondary to benign prostatic enlargement (BPE), causing storage and voiding symptoms, associated with a considerable impairment of the quality of life (2). Surgical therapy of BPH has continuously evolved in recent years. The current gold standard for the endoscopic treatment of BPH is the transurethral resection of the prostate (TURP). Other innovative techniques were developed including Urolift, transurethral laser enucleation (holmium, thulium) and Aquablation therapy. One of the latest technologies for the management of BPH are Optilume BPH Catheter System (Optilume®, Urotronic Inc, Minneapolis, USA) and Rezum Water Vapor Therapy (Rezum System, Bostocn Scientific, Marlborough, MA). The purpose of the present study is to compare between patient experience, symptom relief and functional improvement when using the Optilume BPH Catheter System (Optilume®, Urotronic Inc, Minneapolis, USA) and Rezum Water Vapor Therapy (Rezum System, Boston Scientific, Marlborough, MA).
