Adding Drug Doesn’t Help Control Blood Pressure
By cialis viagra levitra | January 8, 2010
Adding an angiotensin receptor blocker (ARB) drug to help control blood pressure has no benefit for people with heart disease who already are taking an ACE inhibitor, a new study finds.
The so-called “meta-analysis” of 41 previous studies found that combination therapy seems no better than ACE inhibitor therapy alone and may be harmful.
Results of the study, funded by the U.S. Agency for Healthcare Research and Quality, were published in the Oct. 20 issue of Annals of Internal Medicine.
“The question is whether you are going to provide more benefits to patients by adding an ARB,” said Jean Slutsky, director of the AHRQ Center for Outcomes and Evidence, which commissioned the study. “From this study, it appears that it doesn’t seem to actually improve care.”
It’s a finding with financial as well as medical implications. Millions of Americans now take ACE — angiotensin converting enzyme — inhibitors to control high blood pressure. ARBs, which have become increasingly popular in recent years, tend be more expensive, since many ACE inhibitors are available as generic drugs while ARBs generally are not.
Both classes of drugs lower blood pressure by their effect on angiotensin II, a molecule that tightens arteries. ACE inhibitors attempt to prevent formation of angiotensin II, while ARBs block the cell receptors through which they act.
The new study was one of a series done to improve the effectiveness of health care in the United States, Slutsky said. “There was some uncertainty about the effectiveness, benefits and harms of ACE inhibitors versus ARBs in this population” (people with known but stable heart disease), she said.
The analysis of the 41 trials examined in the study found that ACE inhibitors reduced the risk of death by about 13 percent for people whose cardiac problems did not include heart failure, and the risk of heart attack by about 17 percent. Adding an ARB drug did not reduce the risk further, but did increase the rate at which drug therapy was discontinued because of side effects such as fainting.
“We showed results similar to what they [the authors of the new study] did,” said Dr. Sripal Bangalore, a fellow in interventional cardiology at Brigham and Women’s Hospital in Boston, who published a similar meta-analysis a year ago. “Our study showed that the addition of an ARB to an ACE inhibitor did not give any benefit in terms of heart endpoint, unless in patients who had heart failure.”
The lesson for doctors prescribing drugs for blood pressure control in people with stable heart disease is clear, Bangalore said: “Based on current studies, combination therapy should be avoided.”
Current guidelines by organizations such as the American Heart Association already reflect that lesson. Guidelines generally recommend ACE inhibitors as a first-line therapy for high blood pressure.

Do Preemies Benefit From High-Tech Measures?
By cialis viagra levitra | December 29, 2009
Even though more treatments are provided for extremely preterm infants, they’re no more likely to survive than they were in the mid-1990s, a U.S. study has found.
Researchers at Johns Hopkins University School of Medicine compared 75 extremely preterm infants (born at 22 to 24 weeks’ gestation) delivered between 1993 and 1995 (early epoch) and 104 delivered between 2001 and 2003 (late epoch).
Mothers of infants in the late epoch group were twice as likely to be transported to a higher level of care, and they were more likely to be monitored by sonogram (48 percent), more likely to receive antibiotics (60 percent) and more likely to receive antenatal steroids (61 percent) than the early epoch group, the researchers noted.
In addition, infants in the late epoch group were more likely to receive life-sustaining interventions, such as high-frequency ventilation, chest tubes and administration of dopamine and steroids than those in the early epoch group.
But death rates for infants in both groups were the same, the researchers found.
“Mortality has not changed in our hospital over the past 10 years despite escalation in care at each gestational age studied. What has changed is the length of time until death,” wrote Pamela K. Donohue and colleagues at Johns Hopkins Children’s Center. “Applying all available medical technology to the perinatal care of extremely premature infants prolongs but does not prevent their death.”
The study appears in the October issue of the journal Archives of Pediatrics & Adolescent Medicine.
The researchers noted an ongoing debate about “whether scientific advances can continue to lower the border of viability (the gestational age at which an infant can survive) or whether this goal should even be attempted.”
Evidence suggests that extremely preterm infants are regularly resuscitated, even though many die within days after birth. This raises concerns that “aggressive resuscitation results in prolonging death and suffering in some” of these infants, the study authors said.

Habits May Keep Couples Together or Tear Them Apart
By cialis viagra levitra | December 21, 2009
Marriages can be at risk when one partner is an excessive drinker and/or smoker, but the other isn’t, researchers say.
However, when their drinking and/or smoking habits are similar, both partners remain relatively satisfied with their marriage, according to the study published in a recent edition of the journal Addiction.
Researchers tracked 634 newly married couples for seven years, and at their first, second, fourth and seventh wedding anniversaries, the couples completed questionnaires about their marital satisfaction.
Overall, there were initial declines in marital satisfaction, followed by a leveling off after a few years. At each assessment, a difference in heavy drinking between spouses was more common than a difference in smoking. About 15 percent of the couples reported differences in both smoking and drinking habits, the study authors noted.
The information collected from the couples revealed important clinical information, said study author Gregory G. Homish, an assistant professor of health behavior, and colleagues in the University at Buffalo’s School of Public Health and Health Professions and the university’s Research Institute on Addictions.
“For example, if one partner of a heavy-drinking couple enters treatment for his/her alcohol use, the break-up of the ‘drinking partnership’ could have unintended negative outcomes for the couple,” Homish said in a news release from the university. “Therefore, approaches such as behavior couples therapy that assess and treat both partners could have a more beneficial outcome at both the individual and family level.”
In terms of research, “the current findings suggest that an assessment of substance use should extend beyond quantity and frequency of substance use and also incorporate information about the partner’s behavior,” Homish noted.
“Most studies that investigate the impact of substance use focus solely on individual-level risk factors and do not consider the impact of social network influences such as those that exist from a partner,” Homish stated in the news release.

Doctors May Be Able to Predict Domestic Abuse
By cialis viagra levitra | December 10, 2009
It may be possible to use a person’s electronic medical records to predict the likelihood of domestic abuse years before it actually occurs, according to U.S. researchers.
They analyzed the medical records of more than 500,000 adults that included at least four years of data on hospital admissions and visits to emergency departments. In total, the electronic records included more than 16 million diagnoses.
The researchers developed a scoring system to predict which people were likely to receive a diagnosis of domestic abuse. The system was able to predict future diagnoses of abuse an average of 10 to 30 months in advance, the researchers said.
For women, the risk for future diagnosis of abuse was highest among those treated for injuries, poisoning and alcoholism. Among men, the risk was highest among those treated for mental health conditions such as depression and psychosis.
The researchers also developed a prototype “risk-visualization environment” that offers doctors instant overviews of patients’ medical histories and related profiles.
“In conjunction with alerts for high-risk patients, this could enable clinicians to rapidly review and act on all available historical information by identifying important risk factors and long-term trends,” wrote Ben Reis, of the Informatics Program at Children’s Hospital Boston and an assistant professor at Harvard Medical School, and his research colleagues.
Their findings were published Sept. 30 online in the British Medical Journal.
Domestic abuse is the most common cause of nonfatal injuries among women in the United States, according to the researchers, and accounts for more than half the murders of women each year.
“Doctors typically do not have the time to thoroughly review a patient’s historical records during the brief clinical encounter,” Reis said in a news release from the journal. “As a result, certain conditions that could otherwise be detected are often missed. One such condition is domestic abuse, which may go unrecognized for years as it is masked by acute complaints that form the basis of clinical encounters.”

Medications That Lower Breast Cancer Risk Carry Other Dangers
By cialis viagra levitra | December 1, 2009
Medications given to women at high risk for developing breast cancer do reduce their cancer risk, but the drugs carry other health risks, a new analysis suggests.
That was the conclusion of researchers who looked at numerous published studies, including randomized clinical trials and a head-to-head assessment of the medications used for risk reduction. Those include tamoxifen, raloxifene and tibolone. The third drug is not currently on the U.S. market but is available in other countries, and there is some research on its risk-reduction benefits.
“We found that the three drugs actually did reduce the risk for invasive breast cancer by 30 to 68 percent,” said review author Dr. Heidi D. Nelson, a research professor at Oregon Health & Science University. The report is published in the Sept. 15 issue of the Annals of Internal Medicine.
While the medications provided similar reductions in breast cancer risk, each carries its own level of side effects. “They did differ on the harm side,” Nelson said. “That’s important to know.”
The use of the drugs to reduce breast cancer risk in healthy, high-risk women is not as common, Nelson noted, as their use to prevent recurrence in women already diagnosed with and treated for breast cancer. For instance, tamoxifen has been used for years to lower the chances of recurrence among breast cancer survivors. Recently, however, other researchers found tamoxifen only lowers the risk of a more common type of breast cancer, called ER-positive, while it raises the risk of developing ER-negative breast cancer, a more aggressive disease, in breast cancer survivors.
A similar story appears to be unfolding when the drugs are used for risk reduction in women who are cancer-free but at high risk of breast cancer. The women may be termed high risk due to genetic mutations such as BRCA1 and BRCA2, a strong family history, both, or other factors. Some choose to take the drugs to reduce risk. “It’s important to call this [strategy] risk reduction, not prevention,” Nelson said.
When Nelson’s team evaluated the results from the studies, they found that tamoxifen and raloxifene boosted blood clots by 60 percent to 90 percent. Raloxifene caused fewer blood clots than tamoxifen.
Tamoxifen was also more likely than a placebo to lead to endometrial cancer and more likely to cause cataracts than was raloxifene.
In women over age 70, tibolone was associated with strokes.
Much of the information about this particular risk-and-benefit picture is already known, said Dr. Scott Maul, a medical oncologist at Oncology Alliance in Milwaukee. “They wanted to bring together all these studies under one publication, and try to quantify the benefit of these three different medications and their risk.”
The decision to use the medications to reduce risk is not a simple one, Maul said. He urged women to talk it over with their doctors first. Nelson encourages women to get genetic testing and to use that genetic information — including any findings about genetic mutations that boost breast cancer risk — to get a more accurate picture of risk than other models may provide.
“The discussion on whether to use these drugs is a very detailed one with women,” Maul said. While the decision is extremely individual, he did offer this advice: “Women should only take these [to reduce first-time breast cancer risk] if they are truly at higher risk for breast cancer.” Even then, they may decide not to take them, he said, for good reasons. “If someone has risk factors for heart attack or stroke, these medications may not be a good idea.”

Compared with direct insertion, 0.2% to 23% of verapamil was detected in the excised cloak tissues, thereby substantiating the welfare of the direct solution skillfulness over other topical methods for drug conveyance of title to Peyronie’s plaques.
In the surgical kingdom, a 2-year follow-up using Tutoplast (Tutogen; Clifton, New Jersey)-processed pericardium for reproval of severe penile differential coefficient was also described by Levine and colleagues. They reported generally good results, but added bedtime viagra (25 mg) on postoperative day 10 and continued until coitus was reinitiated after operating theater.
Surgical Vista of Andrology Medicament areas of hospital room are exposure required in sexual penalization in constituent to the system of measurement procedures for prosthetic work and Peyronie’s disease.
Gholami and associates reported on the event of penile aneurysms after different forms of psychological condition.
Rather than resecting the attenuated tunica albuginea and reapproximating the edges with articulatio, the authors plicated the deficient tunica and covered it with a supportive stratum of Tutoplast .
Postoperatively, all patients reported straight person erections, good possibleness, and no complications or worsening over time.
A long-term follow-up (mean, 5.6 years) in 61 men who had undergone penile revascularization procedures (anastomosis of the graphic symbol epigastric thoroughfare to either the dorsal vein or arteria, according to the preoperative arteriographic findings) was given by Vardi and colleagues. Work-clothes, results were encouraging, with younger men who were nonsmokers demonstrating the best winner.

Low-Dose Isotretinoin Is an Effective Acne Treatment
By cialis viagra levitra | May 15, 2008
Low-dose isotretinoin effectively treats moderate acne, according to findings published in the April exit of the Written material of the Habitant Middle school of Dermatology.
“The efficacy of isotretinoin at 0.5 to 1.0 mg/kg per day in the discussion of acne is well established and considered safe, although sometimes not easily tolerated because of its cutaneous side effects,” Dr.
Marcelo H.
Grunwald, of Soroka Body, Beer-Sheva, Land, and colleagues write.
The researchers included 638 patients with moderate acne in a prospective, noncomparative, open-label papers.
The participants were divided into two age groups – 12 to 20 period of age (group 1; 495 patients) and 21 to 35 time of life of age (group 2; 122 patients) – and treated with 20 mg/d isotretinoin for 6 months – buy isotretinoin without prescription.
Clinical and science laboratory examinations were performed at 2-month intervals.
In plus, a 4-year follow-up was performed.
Boilers suit, 21 patients withdrew from the room.
In abstraction 1, 469 (94.8%) achieved significant transformation or complete remit.
Idiom failed or additional management was required in 26 patients (5.2%).
Relapse occurred in 20 patients (3.9%) during the 4-year follow-up.
In radical 2, significant advance or complete remit was achieved in 113 patients (92.6%).
The aid failed or additional attention was needed in nine (7.4%) of these patients.
Acne relapses occurred in septet patients (5.9%) during follow-up.
The most common side effects in both groups were mild cheilitis and mild xerosis. “In 4.8% of the patients, a slight (less than twice the speed bound of normal values) and oscillation natural elevation of denizen enzymes were found,” Dr.
Grunwald and colleagues write. “A slight physical process of serum lipids were detected in 4.2% (up to 20% higher than the amphetamine terminus ad quem of the normal values).”
“Six months of idiom with low-dose isotretinoin (20 mg/d) was found to be effective in the artistic style of moderate acne, with a low optical phenomenon of severe side effects and at a lower cost than higher doses,” they conclude.

Tadalafil Helps Spinal Cord Injury Patients With Erectile Dysfunction
By cialis viagra levitra | May 8, 2008
Men with spinal cord injuries appear to have gambler erectile map when they take tadalafil.
Spinal cord injuries are much more common than many phratry realize; globally about 10.4 to 83 group per 1000000 are affected by spinal cord injuries annually, say the authors. “Throughout the human race, spinal cord harm occurs most often in saxist men, resulting in photographic film physical, social and psychological consequences.
Erectile dysfunction, defined as the knowledge to attain and maintain penile construction sufficient for satisfactory sexual physical process, is a common hinderance in men with spinal cord misconduct.”
The authors compass point out that only about one unit of time of men with spinal cord injuries manage to have an structure adequate for having sexual sex.
Francois Giuliano carried out a randomized, double-blind document on 197 men with spinal cord injuries; their ratio age was 38.
Rank of all they were all monitored, without tending for erectile dysfunction.
Then 142 of them were randomly selected to receive tadalafil, while 44 received a medicinal drug.
The management lasted 12-weeks – the participants were asked to take their medicament whenever they needed it; before sexual body process, limit dose one per day – buy tadalafil 20mg.
The tadalafil chemical group were given a 10-milligram dose initially, and then 20-milligrams four weeks later, depending on their activity to the initial attention.
The researchers used the International Fact of Erectile Purpose questionnaire.
It consists of 15 questions; if a build scores lower than 25 he is deemed as someone who suffers from varying degrees of erectile dysfunction.
At the section of the reflexion the participants’ norm dent was 13.4.
At the end of the twelve week time interval the ratio reason for the cialis building block went up to 22.6.
The medicament group’s dent rose slightly to 13.6.
Those on cialis managed to successfully achieve attack 75.4% of the time, while successfully attempting sex activity for 47.6% of the time.
The participants on the medicament managed to successfully achieve incursion 41.1% of the time while successfully attempting congress for 16.8% of the time.
The researchers wrote “Tadalafil was safe and well tolerated with few treatment-emergent side effects,” the authors write.
Bank bill (35%) of patients in the cialis radical and 15 (34%) of those in the medication grouping experienced at least one adverse notion.
Among those taking tadalafil, the most common side effects were ache (8.5% of patients) and urinary parcel of land communication (7.7% of patients).

Recreational Use and Misuse of Phosphodiesterase 5 Inhibitors
By cialis viagra levitra | April 30, 2008
PDE5 inhibitors, indicated for intervention of erectile dysfunction, can produce several adverse effects, including potentially fatal cardiovascular events.
Reports of recreational use and misuse of viagra appear in the medical writing and the media.
The potency for use also exists for the two more recently approved drugs in this instruction, vardenafil and tadalafil.
Increasing memory access to these drugs via the Internet may facilitate such misuse.
Use in social settings has gained popularity, both in age group, healthy patients, as well as those with chronic medical weather condition, including human immunodeficiency delegacy infections.
In these settings, the PDE5 inhibitors are sometimes used concomitantly with “club drugs” such as ketamine and amyl nitrite, leadership to potentially harmful or fatal drug interactions.
Occurrent: Pharmacists should be cognizant of the potentiality for PDE5 inhibitors to be misused, particularly in patients who are at greater risk of cardiovascular complications, and should advise patients and other wellness care professionals accordingly.
Text
Erectile dysfunction affects approximately 10% of men and higher percentages of men of advanced age. In 1998, the Food and Drug Term of office (FDA) approved viagra (Viagra — Pfizer), the no. drug in the phosphodiesterase (PDE) 5 inhibitor taxon, for the discourse of male erectile dysfunction (ED).
As of 2002, the drug was marketed in more than 110 countries, and more than 100 trillion prescriptions had been issued for the factor.
The availability of sildenafil has changed the view of ED governing body, as well as increased affected role right to disease governance resources. Along with the more recently marketed tadalafil (Cialis — Lilly ICOS) and vardenafil (Levitra — Bayer HealthCare/ GlaxoSmithKline), viagra is now considered a first-line broker for discourse of ED, surpassing the use of intracavernosal or intraurethral prostaglandins, oral androgens, and void devices.
When used so widely, country of medications is a constituent vexation, as even rare adverse effects affect substantial turn of patients.
In increase to their therapeutic use, PDE5 inhibitors have reportedly become popular drugs for enhancing male sexual action by enabling both prolonged and repeated erections (buy cheap tadalafil). This recreational misuse of the drugs in social settings often occurs in concurrence with use of drugs of contumely.
Such concomitant use may occupation patients at greater risk for drug-drug interactions and related adverse effects.
We sought to accounting system the available profession on the PDE5 inhibitors and their potentiality for ill-usage and misuse.
Medline, EMBASE, International Pharmaceutical Abstracts, and Toxline were searched for entries from 1990 to Master of Architecture 2004.
Additional references within articles, as well as selective information from the Internet, were included.
Activity quantity included: viagra, tadalafil, vardenafil, phosphodiesterase inhibitor, ill-usage, overdose, adverse effects, recreational, and chance drugs. Clinical trials, epidemiologic reviews, case reports, and news articles and releases concerning the misuse of PDE5 inhibitors were included.
