RESUMO

Prehabilitation aims to increase the endurance capacity of patients who are awaiting major surgery. However, there are no studies investigating the implementation of this demanding and expensive intervention in low-income countries. This study aimed to assess the impact of a 4-week trimodal prehabilitation program on the physical and psychological health of patients waiting for colorectal surgery compared with a control group managed according to enhanced recovery after surgery principles supplemented by nutritional care. This study was a single-centre, randomised controlled trial. The primary outcome measures for the physical aspects were 6-minute walking distance (6MWD) and incentive spirometry, whereas the psychological elements were measured using the 36-item short form survey questionnaire and the hospital anxiety and depression score. In total, data from 149 patients were analysed (77 in the prehabilitation group and 72 in the control group). At the time of surgery, patients in the prehabilitation group had improved 6MWD and incentive spirometry compared with the control group (median (IQR [range]) percentage improvement 131% (112-173 [68-376]) vs. 107% (99-120 [63-163]); p < 0.001 and 113% (100-125 [75-200]) vs. 100% (100-112 [86-167]); p < 0.001 respectively). Patients in the prehabilitation group also had reduced anxiety scores compared with the control group (mean (SD) anxiety score (4 (3) vs. 5 (3) respectively; p = 0.032). However, these effects did not translate into improvements in postoperative mortality and morbidity, or a reduction in duration of hospital stay. Trimodal (physical, emotional and nutritional) prehabilitation is able to improve functional status as well as some parameters of emotional and physical well-being of patients waiting for colorectal surgery.

RESUMO

OBJECTIVE: The incidence of inflammatory bowel disease (IBD) is increasing in Eastern Europe. The reasons for these changes remain unknown. The aim of this study was to investigate whether an East-West gradient in the incidence of IBD in Europe exists. DESIGN: A prospective, uniformly diagnosed, population based inception cohort of IBD patients in 31 centres from 14 Western and eight Eastern European countries covering a total background population of approximately 10.1 million people was created. One-third of the centres had previous experience with inception cohorts. Patients were entered into a low cost, web based epidemiological database, making participation possible regardless of socioeconomic status and prior experience. RESULTS: 1515 patients aged 15 years or older were included, of whom 535 (35%) were diagnosed with Crohn's disease (CD), 813 (54%) with ulcerative colitis (UC) and 167 (11%) with IBD unclassified (IBDU). The overall incidence rate ratios in all Western European centres were 1.9 (95% CI 1.5 to 2.4) for CD and 2.1 (95% CI 1.8 to 2.6) for UC compared with Eastern European centres. The median crude annual incidence rates per 100,000 in 2010 for CD were 6.5 (range 0-10.7) in Western European centres and 3.1 (range 0.4-11.5) in Eastern European centres, for UC 10.8 (range 2.9-31.5) and 4.1 (range 2.4-10.3), respectively, and for IBDU 1.9 (range 0-39.4) and 0 (range 0-1.2), respectively. In Western Europe, 92% of CD, 78% of UC and 74% of IBDU patients had a colonoscopy performed as the diagnostic procedure compared with 90%, 100% and 96%, respectively, in Eastern Europe. 8% of CD and 1% of UC patients in both regions underwent surgery within the first 3 months of the onset of disease. 7% of CD patients and 3% of UC patients from Western Europe received biological treatment as rescue therapy. Of all European CD patients, 20% received only 5-aminosalicylates as induction therapy. CONCLUSIONS: An East-West gradient in IBD incidence exists in Europe. Among this inception cohort--including indolent and aggressive cases--international guidelines for diagnosis and initial treatment are not being followed uniformly by physicians.

RESUMO

BACKGROUND: DLG5 p.R30Q has been reported to be associated with Crohn disease (CD), but this association has not been replicated in most studies. A recent analysis of gender-stratified data from two case-control studies and two population cohorts found an association of DLG5 30Q with increased risk of CD in men but not in women and found differences between 30Q population frequencies for males and females. Male-female differences in population allele frequencies and male-specific risk could explain the difficulty in replicating the association with CD. METHODS: DLG5 R30Q genotype data were collected for patients with CD and controls from 11 studies that did not include gender-stratified allele counts in their published reports and tested for male-female frequency differences in controls and for case-control frequency differences in men and in women. RESULTS: The data showed no male-female allele frequency differences in controls. An exact conditional test gave marginal evidence that 30Q is associated with decreased risk of CD in women (p = 0.049, OR = 0.87, 95% CI 0.77 to 1.00). There was also a trend towards reduced 30Q frequencies in male patients with CD compared with male controls, but this was not significant at the 0.05 level (p = 0.058, OR = 0.87, 95% CI 0.74 to 1.01). When data from this study were combined with previously published, gender-stratified data, the 30Q allele was found to be associated with decreased risk of CD in women (p = 0.010, OR = 0.86, 95% CI 0.76 to 0.97), but not in men. CONCLUSION: DLG5 30Q is associated with a small reduction in risk of CD in women.

RESUMO

General transcription factors TFIIA, B, D, E, F, H, and RNA polymerase II (Pol II) are required for accurate initiation of Pol II transcription. The TATA binding protein (TBP), a subunit of TFIID, is responsible for recognition of the TATA box, a core element shared by a category of class II promoters [1]. Recently, novel TBP-like factors (TLFs) have been described in metazoan organisms [2]. In spite of the numerous in vitro studies describing the general role of TBP in RNA polymerase II (Pol lI) transcription initiation, the precise function of TBP and the newly described TLF is poorly understood in vivo. We inhibited TBP and TLF function in zebrafish embryos to study the role of these factors during zygotic transcription. A dominant-negative variant of TLF mRNA and a TBP morpholino antisense oligo was used to block either TLF or TBP function. Both TBP- or TLF-blocked embryos developed normally until the midblastula stage; however, they then failed to gastrulate. Several zygotic regulatory genes were downregulated by a block in either TBP or TLF function, while others were differentially affected. These results suggest that TBP is not universally required for Pol II transcription in vertebrates and that there is a differential requirement for TBP and TLF during early embryogenesis.

RESUMO

BACKGROUND: NOD1/CARD4, a member of the pattern-recognition receptor family, is a perfect candidate as a susceptibility gene for Crohn's disease. Since only limited and conflicting data are available on G796A polymorphisms in inflammatory bowel disease patients, we set out to study the effect of this polymorphism on the susceptibility and course of Crohn's disease in the Hungarian population. METHODS: Four hundred thirty-four unrelated Crohn's disease patients (age at presentation: 28.6+/-9.6 years, female/male: 210/224, duration of Crohn's disease: 8.2+/-6.9 years) and 200 healthy subjects (blood donors) and 136 non-inflammatory bowel disease gastrointestinal controls with chronic gastritis were investigated. NOD1 G796A was detected by using polymerase chain reaction/restriction fragment length polymorphism. Detailed clinical phenotypes were determined by reviewing the medical charts. RESULTS: The frequencies of the variant alleles of NOD1 G796A differed significantly between the Crohn's disease patients and both healthy (GG 49.5% vs. 67%; AG 41.5% vs. 28%; and AA 9.0% vs. 5.2%; p<0.0001) and non-inflammatory bowel disease controls with chronic gastritis. Carriage of the single nucleotide polymorphism of NOD1 G796A proved to be a highly significant risk factor for Crohn's disease compared to both healthy (p<0.0001, OR: 2.1, 95% CI: 1.5-2.9) and non-inflammatory bowel disease controls with chronic gastritis (p=0.008). Significant associations were not found between the different genotypes and the demographic data on the patients or the clinical characteristics of Crohn's disease. The different polymorphisms of pattern-recognition receptors (e.g. NOD2/CARD15 SNP8, SNP12 and SNP13 mutations, the TLR4 D299G polymorphism and NOD1 G796A) did not reveal a mutual basis. CONCLUSIONS: Our results suggest that carriage of the NOD1 G796A mutation increases susceptibility for Crohn's disease in the Hungarian population.

RESUMO

Limited data are available on the frequency of inflammatory bowel diseases in East European countries. A recent study from Hungary reported an increasing incidence rate for ulcerative colitis (from 1.6 to 11.0) and for Crohn's disease (from 0.4 to 4.7) from 1977 to 2001. A similar trend was seen in Croatia. In contrast, other countries (for example, Czech Republic, Poland, Romania, Slovakia, and Baltic countries) reported low incidence and prevalence rates. This review will discuss the available data on the epidemiology of inflammatory bowel diseases in Eastern Europe, as well as consider the possible factors responsible for the differences seen between countries and epidemiological trends.

RESUMO

Limited data are available on the management of inflammatory bowel diseases (IBD) in East European countries. The diagnostic tools and most treatment options are also available in Eastern Europe. The diagnostic procedures commonly used became more sophisticated in the past few years, with a greater use of computed tomography/magnetic resonance imaging and serology testing; however, double contrast barium enema, enteroclysis, and endoscopy remained standard. The medical therapy and surgical strategies are also somewhat different from those applied in Western countries. In ulcerative colitis, besides mesalazine, the use of sulphasalazine is still frequent, while azathioprine is only used in a minority of patients. The use of conventional corticosteroids is common and the rate of non-colorectal cancer associated colectomies is low. In contrast, 5-aminosalicylates are still used for maintenance in Crohn's disease and azathioprine is generally less frequently given compared with Western Europe. Biological agents have also become available about five years ago, yet their use is restricted mainly to specialised centres.

RESUMO

Calcium-dependent protein kinases (CDPKs) in plants are characterized by a four-domain structure including conserved sequences in the catalytic domain, and in the C-terminal calmodulin-like domain. Based on this conservation we have PCR-amplified and isolated a potato cDNA clone (StCPK1) from a library representing an early stage of tuber development. DNA sequence analysis revealed that in the catalytic domain, StCPK1 shares more homology with CDPK-related kinases than with CDPKs; however, like CDPKs, it possesses canonical EF-hands at the calmodulin-like 3' end. StCPK1 exists in a few copies in the potato genome and is abundantly expressed in the sepals of mature flowers. Floral expression of genes homologous to StCPK1 appears to be widespread in the family Solanaceae.

RESUMO

BACKGROUND AND AIMS: The ECCO-EpiCom study investigates the differences in the incidence and therapeutic management of inflammatory bowel diseases [IBD] between Eastern and Western Europe. The aim of this study was to analyse the differences in the disease phenotype, medical therapy, surgery, and hospitalization rates in the ECCO-EpiCom 2011 inception cohort during the first year after diagnosis. METHODS: Nine Western, five Eastern European centres and one Australian centre with 258 Crohn's disease [CD], 380 ulcerative colitis [UC] and 71 IBD unclassified [IBDU] patients [female/male: 326/383; mean age at diagnosis: 40.9 years, SD: 17.3 years] participated. Patients' data were registered and entered in the web-based ECCO-EpiCom database [www.epicom-ecco.eu]. RESULTS: In CD, 36 [19%] Western Europe/Australian and 6 [9%] Eastern European patients received biological therapy [p = 0.04], but the immunosuppressive [IS] use was equal and high in these regions [Eastern Europe vs Western Europe/Australia: 53% vs 45%; p = 0.27]. Surgery was performed in 17 [24%] CD patients in Eastern Europe and 13 [7%] in Western Europe/Australia [p < 0.001, pLogRank = 0.001]. Of CD patients from Eastern Europe, 24 [34%] were hospitalized, and 39 [21%] from Western Europe/Australia, [p = 0.02, pLogRank = 0.01]. In UC, exposure to biologicals and colectomy rates were low and hospitalization rates did not differ between these regions during the 1-year follow-up period [16% vs 16%; p = 0.93]. CONCLUSIONS: During the first year after diagnosis, surgery and hospitalization rates were significantly higher in CD patients in Eastern Europe compared with Western Europe/Australia, whereas significantly more CD patients were treated with biologicals in the Western Europe/Australian centres.

RESUMO

Studying in vitro stem cuttings of Solanum tuberosum induced for tuberization and those of a non-tuberizing Solanum species, differences both in morphology and in gene expression were detected. Stolon formation essentially depended on light while tuberization was triggered by the elevated level of sucrose in the medium. Genes involved in starch synthesis were induced by sucrose in both species, however, starch granules were detected only in potato. A new tuber specific cDNA clone, GM7, encoding a putative metallocarboxypeptidase inhibitor and the cDNA of a proline rich cell wall protein with S. brevidens specific expression were isolated by differential screening. Sucrose mediated transcription of the tuber storage proteins like patatin and proteinase inhibitors (Kunitz-type, winI, GM7) failed in S. brevidens.

RESUMO

BACKGROUND: This section is under preparation and will be included in the next issue. OBJECTIVES: To answer the question: Among very low birth weight infants, what is the effect of prophylactic administration of d-penicillamine on the incidence of acute ROP or severe ROP, and side effects including death? SEARCH STRATEGY: Searches were made of multiple electronic databases, previous reviews including cross references, abstracts, conference/symposia proceedings, and expert informants. SELECTION CRITERIA: Randomized or quasi-randomized controlled trials that administered d-penicillamine to infants less than 2000g birth weight within the day following birth were considered relevant to this review. Additional case series were examined for potential side effects. DATA COLLECTION AND ANALYSIS: Data on clinical outcomes were excerpted by 3 reviewers independently, and consensus reached. Data analysis was conducted according to the standards of the Neonatal Cochrane Review Group. MAIN RESULTS: Two randomized trials on the effects on ROP were identified. When combined, they showed a significantly lower incidence of acute ROP in the treated infants, relative risk of 0.09, 95% CI [0.01,0.71]. Severe stages of ROP could not be analyzed. There was no effect on death rates, relative risk 0.99 95% CI [0.70,1.39]. No side effects were reported, and follow up at one year revealed no significant differences in spasticity or developmental delay, although there were more rehospitalizations among the controls. In other reports of using d-penicillamine in over 140 infants for hyperbilirubinemia, skin rashes were reported in 2 infants and one had vomiting that may have been related. REVIEWER'S CONCLUSIONS: D-penicillamine is unlikely to affect survival, and may reduce the incidence of acute ROP among survivors. Studies to date justify further investigation of this drug in a broader population; careful attention to possible side effects is needed.

RESUMO

BACKGROUND: Retinopathy of prematurity remains a common problem. A low rate of this disorder was unexpectedly observed among infants treated with intravenous d-penicillamine to prevent hyperbilirubinemia. This observation led to the investigation of its use to prevent retinopathy of prematurity. OBJECTIVES: To answer the question: Among very low birth weight infants, what is the effect of prophylactic administration of d-penicillamine on the incidence of acute ROP or severe ROP, and side effects including death? SEARCH STRATEGY: Searches were made of multiple electronic databases, previous reviews including cross references, abstracts, conference/symposia proceedings, and expert informants. The search was updated to November 2000. SELECTION CRITERIA: Randomized or quasi-randomized controlled trials that administered d-penicillamine to infants less than 2000g birth weight within the day following birth were considered relevant to this review. Additional case series were examined for potential side effects. DATA COLLECTION AND ANALYSIS: Data on clinical outcomes were excerpted by 3 reviewers independently, and consensus reached. Data analysis was conducted according to the standards of the Neonatal Cochrane Review Group. MAIN RESULTS: Two randomized trials on the effects on ROP were identified. When combined, they showed a significantly lower incidence of acute ROP in the treated infants, relative risk of 0.09, 95% CI [0.01,0.71]. Severe stages of ROP could not be analyzed.

RESUMO

An ABO-incompatible term infant girl born to parents who are Jehovah's Witnesses was admitted to our neonatal unit with a high serum bilirubin level necessitating exchange transfusion. The parents signed a request that blood should not be administered under any circumstances. However, they authorized us to apply the possible alternative treatments of orally administered D-penicillamine (300 mg/kg per day divided in three doses for 3 days), phototherapy, intravenous fluids, and recombinant human erythropoietin (200 U/kg subcutaneously on every second day for 2 weeks). Herein, we report the outcome of this baby, who was discharged from the our unit in good condition after treatment. Her physical growth and motor milestones at 14 months of age revealed no red flags for neurodevelopmental maturation. To our knowledge, this is the first case of an infant who received such a combined alternative (and "bloodless") treatment of serious ABO hemolytic disease of the newborn.

RESUMO

A method for synchronized in vitro tuber induction in a Hungarian cultivar of Solanum tuberosum designated "Keszthelyi 855" has been developed. It was shown that in this system tuberization and stolon elongation primarily depend on the level of sucrose in the medium. The cytokinin, 6-bensylaminopurine (BAP), also enhances the efficiency of tuber formation, however, only at sucrose concentration above 4% (w/v). The synchronized plant culture provided starting material for isolation of genes specifically expressed in tuberizing Solanum species during the early stage of tuber development. In comparison with the non-tuberizing Solanum brevidens, three types of specific transcripts have been obtained by differential screening. Based on DNA sequence analysis the genes isolated code for the major tuber proteins, patatin and proteinase inhibitors.

RESUMO

UNLABELLED: During a 15-month period 8 patients (1 male, 7 females, mean age 49 years) admitted from different institutions were treated with bile leaks after laparoscopic cholecystectomy. The diagnosis was established by endoscopic retrograde cholangiography. The site of the leakage was the cystic duct in five cases, the common bile duct in one case, the hepatic "bed" in one case and it was undetectable in one case. Five patients had common bile duct stone and one patients also had common bile duct stricture. Endoscopic sphincterotomy was performed in all cases with stone extraction if needed, and stent insertion (7 or 10 Fr straight endoprosthesis) in six cases. The stents were removed after 4-16 weeks in all cases, except the patients with common bile duct stricture, in whom the stent was exchanged for two other endoprostheses to prevent restricture after three months, she is still under treatment. Endoscopic sphincterotomy, stone removal and stent placement were successful in all cases. Symptoms resolved in hours, and the bile leakage stopped in days. Apart from transient serum amylase level elevation in one patient no other complication was observed. CONCLUSION: The endoscopic treatment of bile leakage after laparoscopic cholecystectomy has proved to be a safe and effective method. It may be considered the method of choice in the management of this complication.

RESUMO

UNLABELLED: Endoscopic sphincterotomy for removal of stones from the common bile duct is an established procedure. Large stones, however, can be unavailable for basket trapping and/or extraction in some cases. In these patients, which are at high risk for surgery, endoscopic insertion of biliary endoprosthesis seems to be an alternative approach to dissolution therapy or ESWL. During the last 5 year, among 4081 ERCP-s 879 examinations demonstrated common bile duct (CBD) stones in our institutions. In 81 of these cases, an endoprosthesis was inserted into the CBD after extended endoscopic sphincterotomy because of failure of extraction of the large stones. Also ursodeoxycholic-acid treatment was initiated thereafter. Mean age of patients was 76 yrs (range 46-95 yrs), 51 females and 30 males. Acute complications after procedure were: mild bleeding not requiring transfusion, and 1 perforation treated surgically some days after prosthesis placement. Late complications until now included: peritonitis in 1 case, and recurrent jaundice due to drain clogging in 12 patients. These patient were treated with replacement of endoprosthesis. Remaining patients are well since the procedure and in 26 cases controlled about 17 months after endoprosthesis placement endoscopy verified significantly smaller or no stones in the common bile duct and in 4 cases even the endoprosthesis has disappeared. CONCLUSION: endoscopic insertion of a biliary endoprosthesis is a safe and effective treatment for the huge CBD stones in high risk patients in whom endoscopic sphincterotomy and attempts to remove the stones are not successful. In more than 30% of cases dissolution of stones with ursodeoxycholic acid may be expected.

RESUMO

Thirty-four long-term survivors of a five-year period (1977-1981) weighing 1000 g or less at birth were followed-up at 8-11 years of age. Fifty per cent of this population was qualified as normal. The great majority of the children (24) attended normal school but 7 (20.6%) with need of special help. There were only three children (8.8%) with severe functional impairment. The rate of survival was 30% at the Neonatal Intensive Care Unit of the Department of Pediatrics, University Medical School, Debrecen at that period of time. The authors analyze in detail the connections of the perinatal events and the outcome. While survival was influenced primarily by hemorrhagic complications beyond immaturity, the long-term prognosis depended on birth asphyxia, recurrent apneic spells and requirements for oxygen therapy.

RESUMO

The (re)discovery of the gastric pathogen Helicobacter pylori almost one and a half decade ago completely changed our conception on gastroduodenal ulcer disease and gastric cancer. The most important issue is that Helicobacter pylori induces a mild, antrum dominant chronic pangastritis without increased risk of severe diseases in most of the cases. A smaller part of the infected develops antrum dominant gastritis with increased risk of duodenal ulcer. In a few cases the corpus is also affected, pangastritis occurs with increased risk to develop gastric ulcer and gastric cancer. Until now it is not quite obvious why some of the infected patients get ill while others not, and why different diseases develop in different patients. 1. From the bacterial point of view it is ascertained that toxin-producing strains (VacA, CagA positive) are more likely to induce ulcer formation and gastric carcinoma. 2. Genetic phenotype of the infected patients (blood-group and HLA antigens) may also be of importance. 3. Environmental factors may affect (promote or inhibit) disease development. All of these factors determine the complex immunological, functional and morphological changes characteristic for the developing disease.

RESUMO

Although the incidence of gastric cancer has declined in the past few decades in developed countries, it has remained one of the most frequent malignomas with high mortality. Epidemiological, clinical and basic research studies confirm the role of Helicobacter pylori in the pathogenesis of the tumors of the distal stomach and low-grade MALT lymphomas. On the contrary more and more data suggest a possible protective role of the infection in the gastro-oesophageal reflux disease, tumors of the cardia and adenocarcinoma of the distal oesophagus. The intensive research being done in the past few years prove our previous concept, that the pathogenesis of gastric cancer is a multifactorial process, which is affected by Helicobacter pylori ("a major environmental factor") together with distinct environmental, social and genetic factors. The interaction of these factors and the importance of them urge further investigations, which may differ in different populations.
