Lifestyle Modification Advice for Lowering or Controlling High Blood Pressure: Who's Getting It?

Lifestyle modifications (LSMs) are important in hypertension management. Using data from a population-based sample of hypertensive adults (N=28,457), the authors examined variations in reports of receipt of LSM advice by patient characteristics. Most adults (90.3%) with known hypertension reported receiving some type of advice. Exercise advice was reported most frequently (74.6%), followed by advice to reduce salt intake (69.3%), change eating habits (61.9%), and reduce alcohol intake (43.5%). Compared with adults aged 60 years or older, persons aged 18 to 39 years were more likely to report receipt of advice (odds ratio [OR], 1.42; 95% confidence interval [CI], 1.11-1.81). Overweight persons (OR, 1.64; 95% CI, 1.40-1.93) and obese persons (OR, 2.75; 95% CI, 2.28-3.31) were more likely to report receipt of advice. Persons receiving antihypertensive medication were also more likely to report receiving advice (OR, 2.35; 95% CI, 1.98-2.81). This study demonstrates that older persons, persons not taking antihypertensive medication, and individuals who are not overweight or obese are less likely to report receiving LSM advice.     

Asking the Patient or Measuring Blood Pressure in the Emergency Department: Which One is Best?

Blood pressure (BP) is obtained at the emergency department (ED) in the vast majority of patients; irrespective of chief complaint, and elevated BP, above the threshold for hypertension, is a common observation. In this review, we address the predictive value of measured BP in the ED compared to that of a history of hypertension in patients with chief complaints related to cardiovascular disease. In chest pain patients, a high BP at the ED is associated to a good prognosis, whereas the history of hypertension is associated to a poor prognosis. In heart failure, a high admission BP is consistently linked to a good prognosis, whereas the clinical value of history of hypertension in the ED is unknown. In stroke, there is a U-shaped relation between admission BP and outcome. A history of hypertension is common among stroke patients but does not seem to provide any predictive value in the ED.     

Mortality Amongst Patients of the Glasgow Blood Pressure Clinic was High in the 1970s and 80s but has Fallen Since,Why?

Established in 1968 the Glasgow Blood Pressure Clinic has over 11,000 patients on its computer record. Up to 1980, mortality from all-causes and from cardiovascular causes was high: relative risks compared with two local control populations were greater than 2.0. Since 1980, all-cause mortality has decreased to 1.31 (859 deaths, CI 1.23–1.39). Lower mortality from cardiovascular causes, particularly coronary heart disease, contributes to the decrease. Reasons for the decrease are under investigation currently. Referral of patients with slightly lower blood pressure contributes, as may better blood pressure control with newer antihypertensive drugs. ACE inhibitors and calcium channel blockers were introduced in 1980 and during the 16-year period to 1995, all-cause mortality has decreased most in patients taking ACE inhibitor. A decrease also occurred in patients taking antihypertensive drugs other than ACE inhibitor.     

Relationship of Hypertension,Blood Pressure,and Blood Pressure Control With White Matter Abnormalities in the Women’s Health Initiative Memory Study (WHIMS)—MRI Trial

J Clin Hypertens (Greenwich). 2010;12:203–212. ^©2010 Wiley Periodicals, Inc. This paper evaluates the relationship of blood pressure (BP) levels at Women’s Health Initiative (WHI) baseline, treatment of hypertension, and white matter abnormalities among women in conjugated equine estrogen (CEE) and medroxyprogesterone acetate and CEE-alone arms. The WHI Memory Study—Magnetic Resonance Imaging (WHIMS-MRI) trial scanned 1424 participants. BP levels at baseline were significantly positively related to abnormal white matter lesion (WML) volumes. Participants treated for hypertension but who had BP ≥140/90 mm Hg had the greatest amount of WML volumes. Women with untreated BP ≥140/90 mm Hg had intermediate WML volumes. Abnormal WML volumes were related to hypertension in most areas of the brain and were greater in the frontal lobe than in the occipital, parietal, or temporal lobes. Level of BP at baseline was strongly related to amount of WML volumes. The results of the study reinforce the relationship of hypertension and BP control and white matter abnormalities in the brain. The evidence to date supports tight control of BP levels, especially beginning at younger and middle age as a possible and perhaps only way to prevent dementia.     

Lifestyle Modifications to Lower or Control High Blood Pressure: Is Advice Associated With Action? The Behavioral Risk Factor Surveillance Survey

Routine lifestyle modification advice for managing high blood pressure (BP) is of questionable effectiveness. Using data from the 2005 Behavior Risk Factor Surveillance System, we examined whether receipt of advice is associated with reported adoption of lifestyle modifications. We determined proportions of hypertensive adults taking action to change eating habits, reduce salt intake, exercise, or decrease alcohol consumption to control high BP. We then determined associations between reports of advice given and corresponding actions being taken: 70.1% of respondents reported changing eating habits, 78.7% reported reducing salt intake, 67.1% reported exercising, and 57.9% of those who drank alcohol reported decreasing their consumption. Compared with those who did not recall being given advice, hypertensive adults who recalled being given advice were more likely to change their eating habits (prevalence ratio [PR], 1.62; 95% confidence interval [CI], 1.56-1.67), reduce salt (PR, 1.53; 95% CI, 1.48-1.58), exercise (PR, 1.41; 95% CI, 1.36-1.47), and reduce alcohol consumption (PR, 1.78; 95% CI, 1.70-1.87).     

Changing Guidelines for Metabolic Surgery: Now It’s the Time!

The governing criteria for bariatric surgery dates back from 1991 and is based solely on body mass index (BMI) as the primary operative criterion, restricting surgery to severely obese patients. Although this was a tremendous step forward in standardizing practice, these guidelines now have important limitations. During the two decades since they were crafted, bariatric surgery has evolved. Also, new procedures are now being performed, as demonstrated by level-1 evidence from randomized controlled trials comparing surgical versus clinical approaches to obesity and related diseases. Although simple and inexpensive, BMI is not a good tool to choose the best treatment option. There is little doubt that BMI alone is not an appropriate indication for surgery and could exclude many patients who could benefit from this life-saving treatment, especially patients with T2DM and lower BMIs. In this matter, new guidelines are urgently needed in order to guarantee, regulate, and reimburse metabolic surgery.     

Let’s (Not) Twist Again: Laparoscopic-Assisted Percutaneous Endoscopic Gastrostomy in Paediatric Gastric Volvulus

Introduction

In the setting of intermittent abdominal pain accompanied by gastro-intestinal obstruction, gastric volvulus should be suspected.

Areas Covered

A 10-year-old girl was admitted to our hospital for intermitted abdominal pain associated with recurrent non-bilious vomiting and acute weight loss. The radiological images performed at the district general hospital were reported as negative. After careful review of the imaging, a gastric volvulus was suspected. Exploratory laparoscopy confirmed the diagnosis; laparoscopic-assisted percutaneous endoscopic gastrostomy was performed. The postoperative upper gastro-intestinal study showed stomach in its normal shape and position.

Expert Commentary

Gastric volvulus is a potential life-threatening condition with a good outcome when promptly recognized. Laparoscopic-assisted percutaneous endoscopic gastrostomy is a safe and curative procedure in the case of suspected gastric volvulus, avoiding the need for a secondary procedure. In pediatric patients, it facilitates direct inspection of the stomach and abdominal cavity, reducing the need for a second procedure. This procedure may emerge as a ‘gold standard’ for gastric volvulus treatment.

     

From the Patient’s Perspective: The Impact of Training on Resident Physician’s Obesity Counseling

BACKGROUND

It is uncertain whether training improves physicians’ obesity counseling.

OBJECTIVE

To assess the impact of an obesity counseling curriculum for residents.

DESIGN

A non-randomized, wait-list/control design.

PARTICIPANTS

Twenty-three primary care internal medicine residents; 12 were assigned to the curriculum group, and 11 were assigned to the no-curriculum group. Over a 7-month period (1–8 months post-intervention) 163 of the residents’ obese patients were interviewed after their medical visits.

INTERVENTION

A 5-hour, multi-modal obesity counseling curriculum based on the 5As (Assess, Advise, Agree, Assist, Arrange) using didactics, role-playing, and standardized patients.

MAIN MEASURES

Patient-report of physicians’ use of the 5As was assessed using a structured interview survey. Main outcomes were whether obese patients were counseled about diet, exercise, or weight loss (rate of counseling) and the quality of counseling provided (percentage of 5As skills performed during the visit). Univariate statistics (t-tests) were used to compare the rate and quality of counseling in the two resident groups. Logistic and linear regression was used to isolate the impact of the curriculum after controlling for patient, physician, and visit characteristics.

KEY RESULTS

A large percentage of patients seen by both groups of residents received counseling about their weight, diet, and/or exercise (over 70%), but the quality of counseling was low in both the curriculum and no curriculum groups (mean 36.6% vs. 31.2% of 19 possible 5As counseling strategies, p?=?0.21). This difference was not significant. However, after controlling for patient, physician and visit characteristics, residents in the curriculum group appeared to provide significantly higher quality counseling than those in the control group (std β?=?0.18; R ² change?=?2.9%, P?<?0.05).

CONCLUSIONS

Residents who received an obesity counseling curriculum were not more likely to counsel obese patients than residents who did not. Training, however, is associated with higher quality of counseling when patient, physician, and visit characteristics are taken into account.
