1. The management of hypertension in overweight subjects has been studied. 2. Sixty-three patients were randomly allocated into a ‘dietary management’ or ‘treatment’ group; the sixty-four controls were told of their hypertension and instructed to seek advice from their usual medical attendant. Reassessment was at 1 year. 3. Treated patients consumed a 700 calorie, 1 g NaCl diet daily. 4. Weight loss was greater in the ‘treated’ group. 5. The average fall of blood pressure was slightly greater in the ‘treated’ group.

Obesity is endemic in human populations in the western society, and with mounting evidence that the intestinal ecological environment plays a major role in its pathogenesis, identification of therapies based on intestinal microbiota modulation are gaining attention. Obesity in companion animals is also a common clinical problem. We set out using a multidimensional approach, to determine the effectiveness and safety of a weight loss program for horses incorporating diet restriction and exercise. In addition, we aimed to investigate the effect of this program on the overall intestinal health of overweight sedentary horses. The investigation comprised of a randomized, controlled, 6-week study of 14 overweight sedentary horses and ponies who were blocked for age, gender, and breed (controls n = 7, treatment n = 7). The treatment group were fed a restricted diet (1.4% of body weight dry matter intake) and the control group a maintenance diet (2% of body weight as dry matter intake) over the study period. The treatment group were subjected to a prescribed exercise regime, while the control group were exercised to mimic foraging conditions. Several clinical measurements were taken at the start and end of the study, including morphological parameters, ultrasound measurements of subcutaneous fat, and blood pressure. Fecal microbiota analysis was performed using 16S rRNA gene sequence analysis, and fecal metabolome was analyzed using NMR spectroscopy, on samples taken at weeks 1, 3, and 6 of the study. All horses completed the study period successfully. However, two of the treatment group had to have modified exercise regimes. The treatment group showed significant weight loss (p < 0.00001) and an associated decrease in waste circumference (p < 0.0001) when compared with the control group. The alpha-diversity of the fecal microbiota in the treatment group showed a significant increase from the start to the end of the study period (p < 0.05); however, there was no significant difference between groups at any sampling point. There were significant changes (p < 0.05) in the metabolome in both groups between the start and end of the study, but not between groups at any sampling point. Finally, the resting blood pressure of all horses was significantly lower by the end of the study.

The ketone body precursor 1,3-Butanediol (BD) has been reported to lower blood pressure in male Dahl Salt-sensitive rats fed a 2% NaCl diet and female S.SHR(11) rats on a 0.3% NaCl diet. Treatment in female S.SHR(11) was also associated with weight loss and suppression of renal injury. The present study tested whether BD attenuates hypertension and renal injury in male S.SHR(11) rats. The S.SHR(11) rat is a congenic strain generated from genetic modification of the Dahl S rat. Previously, we demonstrated that the S.SHR(11) rat fed a 0.3% NaCl diet exhibits earlier onset of kidney injury, a greater decline in kidney function compared to the Dahl S rat despite having similar blood pressure, thus providing a better model to test potential therapeutic interventions. Rats (7 -18 weeks old) were divided into two groups: the treatment group that received BD (20%) for 10 weeks via drinking water and controls on ad libitum water and both maintained on a low-salt rodent chow (Teklad 7034, 0.3% NaCl; n=5-6/group). Systolic blood pressure was measured after 9 weeks by tail-cuff plethysmography. After 10 weeks of BD treatment, 24h urine was collected and tissues were harvested. Treated rats were smaller than controls (330.2 ± 14.2 vs. 449.8 ± 22.9 g, p= 0.001). Urine excretion rate was lower in treated rats (11.3± 1.1 vs. 19.6 ± 3.8 ml/day, p=0.047) whereas kidney weight normalized to body weight was higher in this group (0.95 ± 0.04 vs. 0.77 ± 0.03 %, p=0.011). BD did not lower systolic blood pressure (157.0 ±14.0 vs. 163.9 ±14.6 mmHg, p=0.740). Proteinuria was diminished in the treated group, although not significant (135 ± 51 vs. 311 ± 67 mg/day, p= 0.064). Renal fibrosis (7.6 ± 0.61 vs. 9.4 ± 0.95 %, p=0.139), plasma creatinine (0.46 ±0.03 vs. 0.49 ± 0.01 mg/dL, p=0.466), and creatinine clearance normalized to kidney weight (0.57 ±0.05 vs. 0.67 ± 0.02 ml/min, p= 0.138) were not changed by treatment. Blood urea nitrogen was similar between groups (30.7 ± 2.57 vs. 27.4 ± 2.25mg/dL, p= 0.367). The current data demonstrate that BD does not mitigate hypertension nor improve renal function in male S.SHR(11) rats suggesting potential sex differences in the antihypertensive effects of BD. However, weight loss which has been associated with ketogenic interventions such as BD was still observed in this study.

Introduction Intraventricular pressure gradient is regarded as a non-invasive indicator of diastolic function. Salvianolic acid B (Sal-B), a traditional Asian medicine, revealed its usefulness in myocardial infarction models; however, the hemodynamic effect of salvianolic acid B is still unknown. The present study aimed to investigate the intraventricular pressure gradient changes during the development of left ventricular hypertrophy with or without salvianolic acid B and a beta-blocker. Methods In total, 48 rats were divided into four groups; Sham, Non-treatment, salvianolic acid B, and Carvedilol. Aortic coarctation-induced left ventricular hypertrophy was done in three groups and the treatment was started from the third to the sixth week. Blood pressure, conventional echocardiography, and color M-mode echocardiography for measurement of intraventricular pressure gradient were carried out for six consecutive weeks. Results At 4.5 weeks, the LV mass was elevated in the coarctation groups but the blood pressure was significantly lower in salvianolic acid B and Carvedilol groups ( P < 0.05). In the Non-treatment group, the total intraventricular pressure gradient was increased at 4.5 and 6 weeks (2.60 and 2.65, respectively). Meanwhile, the basal intraventricular pressure gradient was elevated at 3 and 6 weeks (1.67 and 1.75) compared with the Sham group. Salvianolic acid B and Carvedilol significantly reduced the basal intraventricular pressure gradient at six weeks compared with the Non-treatment group (1.52 and 1.51 vs 1.75, respectively). Conclusions Salvianolic acid B and Carvedilol promote cardiac function by decreasing the elevated basal intraventricular pressure gradient. The current preclinical results revealed the efficacy of salvianolic acid B as a potential therapy for left ventricular hypertrophy because of the non-blood pressure lowering effect.

Purpose. To determine if a mailed health promotion program reduced outpatient visits while improving health status. Design. Randomized controlled trial. Setting. A midsized, group practice model, managed care organization in Ohio. Subjects. Members invited (N = 3214) were high utilizers, 18 to 64 years old, with hypertension, diabetes, or arthritis (or all). A total of 886 members agreed to participate, and 593 members returned the initial questionnaires. The 593 members were randomized to the following groups: 99 into arthritis treatment and 100 into arthritis control, 94 into blood pressure treatment and 92 into blood pressure control, and 104 into diabetes treatment and 104 into diabetes control. Measures. Outpatient utilization, health status, and self-efficacy were followed over 30 months. Interventions. Health risk appraisal questionnaires were mailed to treatment and control groups before randomization and at 1 year. The treatment group received three additional condition-specific (arthritis, diabetes, or hypertension) questionnaires and a health information handbook. The treatment group also received written health education materials and an individualized feedback letter after each returned questionnaire. The control group received condition-specific written health education materials and reimbursement for exercise equipment or fitness club membership after returning the 1-year end of the study questionnaire. Results. Changes in visit rates were disease specific. Parameter estimates were calculated from a Poisson regression model. For intervention vs. controls, the arthritis group decreased visits 4.84 per 30 months (p < 0.00), the diabetes group had no significant change, and the hypertension group increased visits 2.89 per 30 months (p < 0.05), the overall health status improved significantly (−6.5 vs. 2.3, p < 0.01) for the arthritis group but showed no significant change for the other two groups, and coronary artery disease and cancer risk scores did not change significantly for any group individually. Overall self-efficacy for intervention group completers improved by −8.6 points (p < 0.03) for the arthritis group, and the other groups showed no significant change. Conclusions. This study demonstrated that in a population of 18 to 64 years with chronic conditions, mailed health promotion programs might only benefit people with certain conditions.

A number of studies have established a close association between increased body mass and elevated blood pressure. The presence of obesity in hypertensive subjects is associated with some hemodynamic, metabolic, and endocrinic characteristics: an increased intravascular volume with a high intracellular body water/interstitial fluid volume ratio, increased cardiac output, stroke volume, and left ventricular work while peripheral resistance was reduced or normal. Weight loss of at least 10 kg can reduce blood pressure independently of changes in sodium intake in obese persons of both sexes with mild, moderate, or severe high blood pressure. The fall in arterial pressure in obese hypertensives after weight loss may reverse many of the previously mentioned altered findings and underscore previous epidemiological studies that have shown that weight control could be an important measure in the treatment of hypertension.

AbstractThe therapeutic effectiveness of a chitosan encapsulated bacteriophage cocktail as a smart biocontrol agent was evaluated in this study to be used as a preventative and treatment option for gastrointestinal infections. To evaluate the effect of the bacteriophage formulation on the treatment of gastrointestinal infection, rats were infected with Salmonella enterica, Shigella flexneri, and Escherichia coli. The rats were weighed and their stools cultured. The results showed that the group which had the chitosan encapsulated bacteriophage cocktail did not lose weight after 3 days and had significantly lower group weight changes. Weight loss was significant in the rats that had cefixime administered instead. Positive cultured stools were reduced after 4 days compared to 2 days in the treated group with the chitosan encapsulated bacteriophage cocktail. The chitosan encapsulated bacteriophage cocktail can therefore be effective in the treatment of gastrointestinal infections.

Of 12 overweight women half received 10 wk. of self-control training and the rest received an equal period aimed at increasing determination to lose weight. Half of each treatment group had expressed a preference for the type of treatment they received and half for the other type of treatment. Both groups lost a statistically significant amount of weight, and at a 3-mo. follow-up there was still a significant weight loss. Follow-up at 6 mo. on 9 of the 12 original subjects indicated both groups regained much of their lost weight. There was no evidence that either type of treatment or receiving one's preferred type of treatment was related to weight loss.
