Intracoronary shunt reduces postoperative troponin leaks: a prospective randomized study.

OBJECTIVE: The purpose of this study was to evaluate whether intracoronary shunt usage reduced the myocardial damage on the basis of the cardiac markers when compared with the shuntless anastomosis in off-pump coronary artery bypass grafting (OPCABG) surgery of isolated left anterior descending artery lesions. METHODS: Forty patients who had stable angina with isolated left anterior descending (LAD) coronary artery lesion undergoing OPCABG surgery were randomized into two groups. Shunt group consisted of 20 patients who had OPCABG using intracoronary shunt, whereas the shuntless group consisted of 20 patients who underwent OPCABG without using intracoronary shunt. Cardiac troponin I, CK, and CK-MB before and 24h after the surgery were assessed in the groups. RESULTS: There were no deaths in the study. The two groups were similar with respect to sex and age. Duration of LIMA-LAD anastomosis was significantly higher in the shunt group (p=0.01). There was no significant difference between the groups concerning the preoperative and postoperative CK and CK-MB levels. The preoperative troponin I levels of the groups were not different (p=0.238; NS), whereas postoperative levels of this marker was significantly higher in the shuntless group (p=0.003). CONCLUSION: Intracoronary shunt reduced the postoperative troponin I levels significantly, so it may be indicated in the patients who are thought to be susceptible to transient ischemia.     

The clinical impact of Prostate Imaging–Reporting and Data System classification in patients with haemospermia undergoing multiparametric magnetic resonance imaging of the prostate

In this study, we evaluated the role of the Prostate Imaging–Reporting and Data System (PI-RADS) classification of multiparametric magnetic resonance imaging (mpMRI) to determine the likelihood of prostate cancer (PCa) in patients with haemospermia. Fifty-one patients presenting with haemospermia between 2018 and 2020 were included in this retrospective study. Forty-two of the patients (82.4%) were over 40 years, and the median prostate-specific antigen (PSA) level was 1.4 ng/ml. Fourteen of the patients (27.5%) had recurrent haemospermia. All patients underwent mpMRI, and assessments were classified according to PI-RADS v2. The mpMRI revealed PI-RADS one to four lesions in 10 (19.6%), 30 (58.8%), 6 (11.8%) and 5 (9.8%) patients respectively. One patient with PI-RADS 3 and five with PI-RADS 4 lesions underwent cognitive fusion prostate biopsy depending on MRI findings, and two patients with PI-RADS 4 lesions were diagnosed with PCa. Patients with haemospermia and risk factors, that is aged over 40 years, a high PSA level or familial history of PCa, need a more thorough evaluation with mpMRI.     

Modified Delphi Study on Nursing Practice and Science in Fetal Care

ObjectiveTo identify essential structures, processes, outcomes, and challenges of nursing practice in fetal care and to identify research priorities for nurses in fetal care.DesignWe used a modified Delphi method to achieve consensus.SettingA secure online survey platform.ParticipantsThe expert panel included nurses from the Fetal Therapy Nurse Network. In addition, a multidisciplinary research jury included members of the North American Fetal Therapy Network (NAFTNet).MethodsWe collected data in three consecutive rounds with online questionnaires that were e-mailed to panelists. We used content analysis to generate statements from an initial round of open-ended questions. Statements met consensus if 75% of the panelists ranked it as greater than or equal to 6 on a 1-to-7 Likert scale.ResultsThe 48 nurse panelists and 11 multidisciplinary jury members described a range of nursing processes. Consensus was reached on 96 statements related to the structure, processes, outcomes, and research priorities of nurses in fetal care.ConclusionThe participants agreed that an expert fetal care nursing team is necessary to provide care to women and families during fetal diagnosis and treatment. Ideally, these nurses should coordinate care and provide direct clinical care (e.g., patient counseling) in outpatient prenatal settings and inpatient settings when fetal surgery is involved. Nurses should be supported to take on leadership roles in program development, research, quality improvement, and professional development with relevant professional organizations.     

Rehabilitation of visually handicapped persons (author's transl)]

Appropriate measures of rehabilitation are needed not only persons having lost their sight but also by those who have become severely visually handicapped through illness or injury and thereby have difficulties in carrying out their occupation and in everyday life. The way of proceeding depends on the general factors of the country in question and on the special situation of the individual. Besides Medical care retraining is most important in a general and special way. In order to attain these objectives the supply also of technical aids of various character necessary. The person afflicted should be rehabilitated in a complete way, which means he should be re-introduced into employment as well as into the society and his personal sphere of life. The body responsible for carrying the cost, which is not low, of all measures of rehabilitation is determined by the cause of sight loss or of the handicap.     

The role of hypoxia in pancreatic cancer: a potential therapeutic target?

One of the key factors that correlates with poor survival of patients with pancreatic cancer is the extent of hypoxic areas within the tumor tissue. The adaptation of pancreatic cancer cells to limited oxygen delivery promotes the induction of an invasive and treatment-resistant phenotype, triggering metastases at an early stage of tumor development, which resist in most cases adjuvant therapies following tumor resection. In this article, the authors summarize the evidence demonstrating the significance of hypoxia in pancreatic cancer pathogenesis and discuss the possible hypoxia-induced mechanisms underlying its aggressive nature. We then conclude with promising strategies that target hypoxia-adapted pancreatic cancer cells.     

Chronic hepatitis C responds poorly to combination therapy in chronic hepatis B carriers

BACKGROUND: The effect of conventional interferon-based therapy of hepatitis B virus (HBV) and hepatitis C virus (HCV) dual infection is controversial. Yet, no studies have been carried out into pegylated interferon treatment for chronic HBV/HCV coinfection. We aimed to evaluate the response rate and side effects of conventional or pegylated interferon combined with ribavirin on chronic HBV/HCV coinfection therapy. METHODS: The study included 36 chronic hepatitis patients (M/F: 28/8, mean age 47+/-12 years) who were positive for HBsAg and anti-HCV. They were tested for the presence of HBV-DNA by hybridisation assay, and the samples giving negative results were retested by polymerase chain reaction (PCR). All patients were tested for HCV-RNA using PCR, and the HCV genotype was determined. RESULTS: Nineteen patients were given standard interferon either alone or in combination with ribavirin, whereas 17 were given pegylated interferon and ribavirin combination therapy. None of the patients had HBV-DNA positivity; however, all had HCV-RNA detectable by PCR. All the patients had HCV genotype 1b. The mean alanine aminotransferase and aspartate aminotransferase levels were 118+/-65 U/l and 90+/-95 U/l respectively. Five patients in each group discontinued the treatment due to side effects. Only two patients (one from each group) reached sustained virological response. CONCLUSION: Neither pegylated nor conventional interferon based regimes were effective for HBV/HCV coinfection, in which the dominant virus was HCV. Pegylated interferon and ribavirin therapy was not superior to conventional interferon based regimes in the treatment of HBV/HCV coinfection.     

Long-Term Effect of Interferon Therapy in Patients with HBeAg Positive Chronic Hepatitis B Infection

Introduction  

Several studies have reported that interferon therapy increases elimination rate of HBeAg and anti-HBe seroconversion in chronic hepatitis B (CHB) patients. We aimed to evaluate long-term results of interferon-α treatment in HBeAg positive CHB patients in a country with exclusively D genotype.
