Combined effect of physical exercise and hormone replacement therapy on cardiovascular and metabolic health in postmenopausal women: A systematic review and meta-analysis.

The cardioprotective effect of postmenopausal hormone replacement therapy (HRT) has been demonstrated in several studies. Similarly, physical exercise has yielded positive results. However, the effects of their combination remain inconclusive. This review describes the combined effects of physical exercise and hormone therapy on cardiovascular and metabolic health in postmenopausal women. We searched the Scopus, Web of Science, PubMed, and Embase databases and included randomized controlled trials published up to December 2021 on the combined effects of physical exercise and hormone therapy on cardiovascular and metabolic health in postmenopausal women. We identified 148 articles, of which only seven met the inclusion criteria (386 participants; 91 [23%] HRT + exercise; 104 [27%] HRT; 103 [27%] exercise; 88 [23%] placebo). The combined treatment further decreased systolic blood pressure (SBP) compared to the isolated effect of aerobic training (AT) (mean difference [MD]=-1.69; 95% confidence interval [CI]=-2.65 to -0.72, n=73). Nevertheless, it attenuated the decrease in diastolic blood pressure (DBP) (MD=0.78; 95%CI: 0.22-1.35, n=73), and the increase in peak oxygen consumption (VO2 peak) promoted by exercise (AT + HRT=2.8±1.4 vs AT + placebo=5.8±3.4, P=0.02). The combination of AT and oral HRT improved SBP. However, AT alone seemed to have a better effect on physical fitness and DBP in postmenopausal women.

Role of aerobic physical training on cardiac autonomic and morphophysiological dysfunction in hypertensive rats subjected to ovarian hormone deprivation.

Here we investigated the effects of physical training on cardiovascular autonomic control and cardiac morphofunctional parameters in spontaneously hypertensive rats (SHRs) subjected to ovarian hormone deprivation. Forty-eight 10-week-old SHRs were divided into two groups: ovariectomized (OVX, n=24) and sham (SHAM, n=24). Half of each group (n=12) was trained by swimming for 12 weeks (OVX-T and SHAM-T). Cardiac morphology and functionality were assessed using echocardiography, and autonomic parameters were assessed using double pharmacological autonomic block, baroreflex sensitivity (BRS), and analyses of heart rate variability (HRV) and blood pressure variability (BPV). Ovariectomy did not influence the cardiac autonomic tonus balance unlike physical training, which favored greater participation of the vagal autonomic tonus. Ovariectomy and aerobic physical training did not modify HRV and BRS, unlike BPV, for which both methods reduced low-frequency oscillations, suggesting a reduction in sympathetic vascular modulation. Untrained ovariectomized animals showed a reduced relative wall thickness (RWT) and increased diastolic and systolic volumes and left ventricular diameters, resulting in increased stroke volume. Trained ovariectomized animals presented reduced posterior wall thickness and RWT as well as increased final diastolic diameter, left ventricular mass, and stroke volume. Ovarian hormone deprivation in SHRs promoted morphofunctional adaptations but did not alter the evaluation of cardiac autonomic parameters. In turn, aerobic physical training contributed to a more favorable cardiac autonomic balance to the vagal autonomic component and promoted morphological adaptations but had little effect on cardiac functionality.

Five-year follow-up of patients with chronic C hepatitis and sustained virological response.

OBJECTIVE: to assess persistence of sustained viral response at 5 years of follow-up in patients with chronic viral hepatitis C treated with pegylated interferon and ribavirin. DESIGN: a descriptive study. PATIENTS: from August 2001 to May 2004, all patients treated at our center with pegylated interferon and ribavirin who achieved a sustained viral response were consecutively enrolled (93 patients). Demographic, histological, biochemical, and virological data were collected during treatment and 5 years after achievement of the sustained viral response. Eighty-six percent of patients enrolled (n = 80) attended the control visit at 5 years. RESULTS: mean age of enrolled patients was 41 years (standard deviation = 10 years), and 30.1% (n = 28) were women. Liver biopsy had been performed before treatment in 68.8% of patients (n = 64), showing no or mild fibrosis in 62.3% (F0 and F1) and significant fibrosis and cirrhosis in 37.7% (F ≥ 3). Genotype distribution was: 58.1% genotype 1 (n = 54); 8.6% genotype 2 (n = 8); 24.7% genotype 3 (n = 23); 7.5% genotype 4 (n = 7), and indeterminate in one patient. Only one patient experienced virological recurrence. All other patients had negative HCV RNA levels and, in the absence of other liver diseases, normal ALT levels. CONCLUSION: in patients treated with pegylated interferon and ribavirin with sustained viral response, long-term recurrence rate was very low.

Usefulness of a delayed test for the diagnosis of Helicobacter pylori infection in bleeding peptic ulcer.

AIM: To evaluate (i) the diagnostic usefulness of a delayed test in initially negative patients; and (ii) the reliability of the rapid urease test, histology or a combination of the two to diagnose Helicobacter pylori during emergency endoscopy in a large clinical practice series. PATIENTS AND METHODS: Records of patients with ulcer bleeding from 1995 to 2000 were reviewed. Patients with initially negative tests were retested 4-8 weeks after the bleeding episode. Sensitivity of urease, histology or a combination of the two to detect H. pylori at initial endoscopy and the efficacy of delayed Urea Breath Test in detecting missed infection was determined. RESULTS: The study included 429 patients. A delayed second test detected H. pylori infection in 57 out of 72 (79%) of initially negative patients. The sensitivity for detecting H. pylori was 76%, 78% and 86% for urease, histology and their combination, respectively. The prevalence of H. pylori was 95% in duodenal and 88% in gastric ulcer. In addition, only one test was performed in 17 of the 32 patients who were considered negative. CONCLUSION: Not even the combination of a negative urease and histology in the initial endoscopy is able to rule out infection in bleeding ulcer patients. A delayed test should be performed to rule out Helicobacter pylori infection completely.

[Autoimmune hemolytic anemia associated with ulcerative colitis]. / Anemia hemolítica autoinmunie asociada a colitis ulcerosa.

The incidence of immunological disorders has been reported to be greater in patients with inflammatory bowel disease than among the general population. The association of ulcerative colitis (UC) and autoimmune hemolytic anemia (AIHA) was first described in the early 1950s but no more than 50 cases have been described in the international literature. Detailed description of the pathogenic mechanisms involved in this association is lacking. The clinical course of AIHA and treatment response in these patients seems to be independent of UC, sometimes requiring immunosuppressive treatment and even surgery. We present 2 cases of AIHA associated with UC with distinct response to conventional treatment. We also review the literature on the subject.

High-dose, ten-day esomeprazole, amoxicillin and metronidazole triple therapy achieves high Helicobacter pylori eradication rates.

BACKGROUND: Strong acid inhibition using esomeprazole increases cure rates with triple therapy and 10-day treatments are more effective than 7-day ones. The combination of amoxicillin plus metronidazole at full doses, and using a physiologically-correct schedule three times a day, and has been shown to overcome metronidazole resistance and to achieve good eradication rates. AIMS: To assess the eradication rate of a new first-line treatment regimen associating strong acid inhibition, amoxicillin and metronidazole and to evaluate tolerance. METHODS: Patients from eight hospitals were included. Helicobacter pylori status was assessed by at least one of the following: histology, culture, rapid urease test or urea breath test (UBT). Ten-day treatment was prescribed comprising esomeprazole 40 mg twice a day plus amoxicillin 1 g and metronidazol 500 mg both three times a day. Helicobacter pylori cure was assessed by UBT. RESULTS: A hundred and thirty-six patients were enrolled. Mean age was 52.6 ± 16 years and 59.6% of patients were men. Main indications for treatment were: uninvestigated dyspepsia (13.6%); functional dyspepsia (18.2%); gastric ulcer (21.8%); and duodenal ulcer (39.8%). Helicobacter pylori eradication was achieved in 112 of the 127 patients who returned for follow-up. Eradication rates were 82.4% (95% CI: 74.7-88.1) by intention-to-treat analysis and 88.2% (95% CI: 81.2-92.8) by per protocol. Treatment was well tolerated and no major side effects were reported. Nine patients complained of mild side effects. CONCLUSIONS: Cure rates of the combination of esomeprazole, amoxicillin and metronidazole are high and the treatment was well tolerated. This pilot study warrants the comparison of this schedule with current standards.
