Rebozo Technique for Fetal Malposition in Labor

Fetal occiput posterior position is associated with increased maternal and fetal morbidities. Currently, clinicians have limited evidence‐based techniques or tools to remedy fetal occiput posterior position. The traditional Mexican rebozo technique of pelvic massage, sifting, or jiggling offers a potentially valuable tool to help correct fetal malposition. This article reviews the adaptation of 3 rebozo techniques that can be used in labor to encourage optimum fetal positioning; outlines hospital considerations for safety, fetal heart rate monitoring, and universal precautions; and reviews the implementation plan to introduce and sustain use of the rebozo in a large academic medical center.     

Gastroduodenal cytomegalovirus infection is common in kidney transplantation patients

OBJECTIVE: Cytomegalovirus (CMV) infection is known to cause ulcerations, erosion and mucosal haemorrhage in the gastrointestinal tract. The aim of this study was to report the CMV findings in the gastroduodenal mucosa of kidney transplantation patients and immunocompetent controls. MATERIAL AND METHODS: Forty-six kidney transplant patients with upper gastrointestinal symptoms and 43 immunocompetent, dyspeptic patients (controls) prospectively underwent oesophagogastroduodenoscopies (OEGDs), with biopsies from the duodenum and stomach. CMV was demonstrated by immunohistochemistry, both in frozen sections using a monoclonal antibody against CMV-specific antigens (pp65 matrix protein) and in paraffin sections by means of a monoclonal antibody against the delayed early protein (p52). RESULTS: CMV was detected in the gastric mucosa in 30% of the kidney transplant patients and in 9% of the controls (p<0.05) and in the duodenal mucosa in 70% and 35%, respectively (p<0.01). The total frequency of CMV findings was similar in patients who underwent OEGDs <1 year and >1 year after transplantation. CMV inclusions were found only in transplantation patients <1 year after transplantation (n=9). CMV findings, especially inclusions, in the gastric biopsies were associated with nausea and upper gastric pain. Histopathological findings in CMV-positive samples were non-specific, focal inflammation in haematoxylin-eosin-stained preparations, while CMV p52 staining showed inclusions in either the epithelial or endothelial cells. CONCLUSIONS: CMV could be detected in the gastroduodenal mucosa in 74% of kidney transplantation patients and in 40% of immunocompetent controls (p<0.01). CMV diagnostics are always recommended when gastroduodenal biopsies of kidney transplantation patients are performed.     

Association analysis of the polymorphism T1128C in the signal peptide of neuropeptide Y in a Swedish hypertensive population

OBJECTIVE: The neuropeptide Y (NPY) signal peptide polymorphism T1128C has been linked to several risk factors for cardiovascular disease. The aim of the present study was to evaluate the significance of this polymorphism for cardiovascular and cerebrovascular disease outcome. DESIGN: In a prospective study cohort, 1032 hypertensive patients (174 myocardial infarction and 170 stroke patients and 688 matched controls) were analysed for the T1128C polymorphism in the NPY gene. METHODS: The dynamic allele specific hybridization (DASH) method was used for genotyping. Serum from the same participants was analysed for total cholesterol, high-density lipoprotein (HDL), low-density lipoprotein (LDL) and triglycerides. RESULTS: The frequency of the NPY T1128C polymorphism was 8.4% among patients with a myocardial infarction or stroke, as compared to 5.1% in the control group (P = 0.040). The difference remained significant after adjustment for the cardiovascular risk factors age, sex, smoking status, body mass index, systolic and diastolic blood pressure, presence of diabetes, total cholesterol, HDL, LDL and triglycerides. CONCLUSIONS: The present study indicates that the NPY T1128C polymorphism is an independent predictor for myocardial infarction and stroke in a Swedish hypertensive population.     

Pulmonary Arterial Wedge Pressure at Rest and During Exercise in Healthy Adults: A Systematic Review and Meta-analysis

Background

The pulmonary arterial wedge pressure (PAWP) response to exercise may unmask latent heart failure with preserved ejection fraction. There remains a lack of consensus over threshold values for PAWP during exercise. A systematic review of studies examining PAWP by means of right heart catheterization at rest and during exercise in healthy individuals was performed.

Long-term outcomes of optimized medical management of outpatients with stable coronary artery disease

The objective of this study was to assess long-term clinical outcomes and their correlates in medically managed outpatients with stable angina pectoris, healed myocardial infarction (MI), or documented asymptomatic coronary artery disease (CAD). Management strategy emphasized maximally tolerated medical therapy and modification of coronary risk factors. Referral to invasive coronary interventions followed stricter criteria than standard published guidelines. Primary study outcomes were all-cause mortality or nonfatal myocardial infarction. Secondary study outcomes included cardiac death, unstable angina, or coronary revascularization. A total of 693 men and women with proved CAD (mean age 67 years at entry, 85% men, 41% with history of MI) were enrolled. The annual incidence of nonfatal MI, cardiac mortality, and total mortality was 2.2%, 0.8%, and 1.4%, respectively, during an average follow-up of 4.6 years. Coronary revascularization was performed in 24% of subjects; unstable or progressive anginal symptoms were the most common reasons for revascularization. In patients with documented stable CAD, a management strategy based on intensive medical therapy and modification of established coronary risk factors was associated with excellent long-term outcomes. Thus, coronary interventions can be safely delayed until clinical instability ensues, without increased risk of MI or death. This treatment approach represents a viable alternative to invasive strategies.
