    The aim of this study was to investigate the biological outcomes of bone-level implants restored with long vs. short abutments, with regard to the 'one abutment at one time' protocol. The systematic search was performed in five databases: MEDLINE (PubMed), EMBASE, Web of Science, Scopus, and CENTRAL for randomized controlled trials up to January 14, 2023. Data were collected for marginal bone loss, bleeding on probing, and probing pocket depth by two reviewers. As effect size measure, mean difference (MD), and risk ratio (RR) were used for continuous and categorical outcomes, R-statistics software was used for conducting statistical analyses. For quality and certainty assessment, Risk of Bias Tool 2, ROBINS-I, and GRADE approach were used. The search resulted in 4055 records without any duplicates. After title, abstract, and full-text analysis, eight articles were found eligible for inclusion. Bone-level and platform-switched implants presented less marginal bone loss after 6 months and 1 year as well, when long abutments were used (MD 0.63, 95% CI: [-0.16; 1.42]) and (MD 0.26, 95% CI: [-0.02; 0.53]). However, subgroup analysis revealed no difference in marginal bone loss when applying 'one abutment at one time' protocol (p = 0.973). Bleeding on probing and probing pocket depth presented similarly good results in both groups without almost any differences (RR 0.97, 95% CI: [0.76; 1.23]) and (MD -0.05, 95% CI: [-1.11; 1.01]). Longer abutments on bone-level implants seem to be a favorable choice for decreasing early marginal bone loss, irrespective of connection timing

It does not influence the initiation of adjuvant therapy and radiological control, and results in favourable cosmetic outcome. Aim: Assessing the Hungarian data of immediate postmastectomy breast reconstructions, and comparing them to international findings. Method: Between May, 2011 and September, 2014 121 therapeutic and prophylactic, postmastectomy immediate breast reconstructions were performed in 100 patients. The clinico-pathological findings were assessed retrospectively, and surgical, oncological and cosmetic outcomes were evaluated statistically. Results: The mean age of patients was 42.6 years, the follow up time was 29.4 months, and the duration of operation was 132 minutes. Skin-sparing mastectomy was performed most commonly (64%) with submuscular tissue expander placement (70%). Early postoperative complication was identified in 18 patients, and loco-regional recurrence in 1 patient. Most patients (89%) were satisfied with the cosmetic outcome. The average initiation time of adjuvant therapy was 4.8 weeks. Conclusions: Immediate breast reconstruction is a safe and effective option in line with international findings. Orv.

    The significant need for breast reconstruction resulting from the spread of oncoplastic breast surgery raises a number of systemic issues. Clarification and regulation of the indications are needed for aesthetic changes of the reconstructed breast due to oncotherapy treatments, ageing and technical problems of implants; a number of operations, targeted aesthetic goals as well as surgical capacities and financial background should also be determined.Our aim was to conduct a survey on the opinions and needs of the Hungarian breast cancer population about a modern breast reconstruction system.A study was conducted enrolling 500 patients who underwent mastectomy with immediate or delayed reconstruction. A structured questionnaire containing eleven questions was used to measure the attitude for loss and reconstruction of breast, the expectation of cosmetic outcome and qualification of the operating surgeon and the needs relating to the health system and funding.The median age was 47 years (min.-max.: 26-73), 59% (n = 294) was married and 52% (n = 260) had graduated in university. The majority of women (70%; n = 348) would like to have nakedly also similar breasts after the reconstruction process. To achieve this, 43% (n = 217) and 37% (n = 184) would undergo maximum two or four procedures, respectively, supported by the national health insurance company. 86% (n = 430) would like to choose qualified breast surgeon for her treatment.The modern oncoplastic treatment raises complex, systemic issues. Women with breast cancer would like to have qualified breast surgeons restoring their breasts by two operations, all funded by the national health insurance company.

    Background: Acute pancreatitis (AP) is one of the most common cause of hospitalization among gastrointestinal diseases worldwide. Although most of the cases are mild, approximately 10–20% of patients develop a severe course of disease with higher mortality rate. Scoring systems consider age as a risk factor of mortality and severity (BISAP; >60 years, JPN>70 years, RANSON; >55 years, APACHE II >45 years). If there is a correlation between aging and the clinical features of AP, how does age influence mortality and severity?Aim: This study aimed to systematically review the effects of aging on AP.Methods: A comprehensive systematic literature search was conducted in the Embase, Cochrane, and Pubmed databases. A meta-analysis was performed using the preferred reporting items for systematic review and meta-analysis statement (PRISMA). A total of 1,100 articles were found. After removing duplicates and articles containing insufficient or irrelevant data, 33 publications involving 194,702 AP patients were analyzed. Seven age categories were determined and several mathematical models, including conventional mathematical methods (linear regression), meta-analyses (random effect model and heterogeneity tests), meta-regression, funnel plot and Egger's test for publication bias were performed. Quality assessment was conducted using the modified Newcastle–Ottawa scale. The meta-analysis was registered in the PROSPERO database (CRD42017079253).Results: Aging greatly influences the outcome of AP. There was a low severe AP incidence in patients under 30 (1.6%); however, the incidence of severe AP showed a continuous, linear increase between 20 and 70 (0.193%/year) of up to 9.6%. The mortality rate was 0.9% in patients under 20 and demonstrated a continuous linear elevation until 59, however from this age the mortality rate started elevating with 9 times higher rate until the age of 70. The mortality rate between 20 and 59 grew 0.086%/year and 0.765%/year between 59 and 70. Overall, patients above 70 had a 19 times higher mortality rate than patients under 20. The mortality rate rising with age was confirmed by meta-regression (coefficient: 0.037 CI: 0.006–0.068, p = 0.022; adjusted r2: 13.8%), and severity also (coefficient: 0.035 CI: 0.019–0.052, p < 0.001; adjusted r2: 31.6%).Conclusion: Our analysis shows a likelihood of severe pancreatitis, as well as, pancreatitis-associated mortality is more common with advanced age. Importantly, the rapid elevation of mortality above the age of 59 suggests the involvement of additional deteriorating factors such as co-morbidity in elderly

    Eosinophil Counts in the Small Intestine and Colon of Children Without Apparent Gastrointestinal Disease: a Meta-analysis

    Get PDF
    OBJECTIVES: The aim of the current study was to review the available data regarding eosinophil density in healthy tissue specimen originating from lower gastrointestinal segments to support suggested diagnostic cut-offs widely used in clinical practice. METHODS: A systematic search was performed in three different databases. Calculations were made with Comprehensive MetaAnalysis software using random effects model. Cell number measurements were pooled using the random effects model and displayed on forest plots. Summary point estimations, 95% Confidence Intervals (CIs), and 95% Prediction Intervals (PIs) were calculated. RESULTS: The cumulative mean cell numbers were 8.26 (95% CI: 3.49, 13.03) with PI of 0-25.32 for the duodenum, 11.51 (95% CI: 7.21, 15.82) with PI of 0-60.59 for the terminal ileum, and 11.10/HPF (95% CI: 9.11, 13.09) with PI of 0.96-21.23 in the large intestine and the rectum (HPF area = 0.2 mm). Previous studies included control patients with irritable bowel syndrome (IBS) and functional GI disorders. As mucosal eosinophils have a role in their pathomechanism, those patients should have been excluded. A critical point of interpreting reported data is that HPF is relative to the technical parameters of the microscopes, therefore it is important to report findings in cell/mm. CONCLUSIONS: The present meta-analysis does not support the higher (>20) or lower (<10) cut-off values for healthy tissue eosinophil number. In contrast to the esophagus, there is no normal cut-off eosinophil density in the small intestine and the colon. A prospective, multi-center study to establish normal mucosal eosinophil density is clearly needed

    BACKGROUND: Benign biliary stricture is a rare condition and the majority of the cases are caused by operative trauma or chronic inflammation based on various etiology. Although the initial results of endoscopic, percutaneous and surgical treatment are impressive, no comparison about long term stricture resolution is available. AIMS: The goal of this study was to compare the long term disease free survival in benign biliary strictures with various etiology after surgery, percutaneous transhepatic-and endoscopic treatment. METHODS: PubMed, Embase, and Cochrane Library were searched by computer and manually for published studies. The investigators selected the publications according to the inclusion and exclusion criteria, processed the data and assessed the quality of the selected studies. Meta-analysis of data of 24 publications was performed to compare long term disease free survival of different treatment groups. RESULTS: Compared the subgroups surgery resulted in the highest long term stricture resolution rate, followed by the percutaneous transhepatic treatment, the multiple plastic stent insertion and covered self-expanding metal stents (SEMS), however the difference was not significant. All compared methods are significantly superior to the single plastic stent placement. Long term stricture resolution rate irrespectively of any therapy is still not more than 84%. CONCLUSIONS: In summary, the use of single plastic stent is not recommended. Further randomized studies and innovative technical development are required for improving the treatment of benign biliary strictures

    Compared efficacy of preservation solutions on the outcome of liver transplantation: Meta-analysis

    Get PDF
    AIM: To compare the effects of the four most commonly used preservation solutions on the outcome of liver transplantations. METHODS: A systematic literature search was performed using MEDLINE, Scopus, EMBASE and the Cochrane Library databases up to January 31(st), 2017. The inclusion criteria were comparative, randomized controlled trials (RCTs) for deceased donor liver (DDL) allografts with adult and pediatric donors using the gold standard University of Wisconsin (UW) solution or histidine-tryptophan-ketoglutarate (HTK), Celsior (CS) and Institut Georges Lopez (IGL-1) solutions. Fifteen RCTs (1830 livers) were included; the primary outcomes were primary non-function (PNF) and one-year post-transplant graft survival (OGS-1). RESULTS: All trials were homogenous with respect to donor and recipient characteristics. There was no statistical difference in the incidence of PNF with the use of UW, HTK, CS and IGL-1 (RR = 0.02, 95%CI: 0.01-0.03, P = 0.356). Comparing OGS-1 also failed to reveal any difference between UW, HTK, CS and IGL-1 (RR = 0.80, 95%CI: 0.80-0.80, P = 0.369). Two trials demonstrated higher PNF levels for UW in comparison with the HTK group, and individual studies described higher rates of biliary complications where HTK and CS were used compared to the UW and IGL-1 solutions. However, the meta-analysis of the data did not prove a statistically significant difference: the UW, CS, HTK and IGL-1 solutions were associated with nearly equivalent outcomes. CONCLUSION: Alternative solutions for UW yield the same degree of safety and effectiveness for the preservation of DDLs, but further well-designed clinical trials are warranted

    Gender difference in the effects of interleukin-6 on grip strength - a systematic review and meta-analysis

    Get PDF
    BACKGROUND: Aging sarcopenia characterized by low muscle mass with low muscle strength affects men and women differently. The contribution of interleukin-6 (IL-6) to sarcopenia has been suggested based on a negative correlation between plasma IL-6 and muscle function described by some studies. However, no consensus regarding clinically relevant cut-off criteria has been reached. Another question arises whether pooling male and female data is an accurate way to determine the predictive value of IL-6 in sarcopenia. The present meta-analysis was designed to assess: (1) whether plasma IL-6 in aged populations in fact correlates negatively to muscle strength; (2) whether such a correlation exists both in men and in women; and (3) whether plasma IL-6 shows a gender difference in old age. METHODS: We applied the preferred reporting items for systematic review and meta-analysis protocols (PRISMA). We searched PubMed and Embase for papers that reported data on individuals over 65 without inflammatory diseases. We extracted either separate male and female data on plasma IL-6 along with at least one muscle parameter or correlation coefficient between plasma IL-6 and these parameters. Random effect models calculated with DerSimonian and Laird weighting methods were applied to analyze correlation coefficients and gender difference in plasma IL-6. Egger's test was used to assess the small study effect. RESULTS: Twenty articles out of 468 records identified were suitable for analyses. Plasma IL-6 correlates negatively with grip strength in mixed populations and also separately in men [- 0.25 with 95% confidence interval (CI): - 0.48, - 0.02] and in women (- 0.14 with 95% CI: - 0.24, - 0.03). However, contrary to expectations, men with better muscle condition have higher plasma IL-6 than women of similar age with worse muscle condition (plasma IL-6 male-female difference: 0.25 pg/mL with 95% CI: 0.15, 0.35). CONCLUSION: This is the first study to demonstrate that a higher predictive IL-6 cut-off level should be determined for aging sarcopenia in men than in women

    Noninvasive ventilation improves the outcome in patients with pneumonia-associated respiratory failure: Systematic review and meta-analysis

    Get PDF
    Noninvasive ventilation (NIV) is beneficial in exacerbations of chronic obstructive pulmonary disease (COPD), but its effectiveness in pneumonia-associated respiratory failure is still controversial. In the current meta-analysis, we aimed to investigate whether the use of NIV before intubation in pneumonia improves the mortality and intubation rates of respiratory failure as compared to no use of NIV in adults.We searched three databases from inception to December 2019. We included studies, in which pneumonia patients were randomized initially into either NIV-treated or non-NIV-treated groups. Five full-text publications, including 121 patients, reported eligible data for statistical analysis.With NIV the overall hospital mortality rate seemed lower in patients with pneumonia-associated respiratory failure, but this was not significant [odds ratio (OR) = 0.39; 95% confidence interval (CI): 0.13-1.14; P = 0.085]. In the intensive care unit, the mortality was significantly lower when NIV was applied compared to no NIV treatment (OR = 0.22; 95% CI: 0.07-0.75; P = 0.015). NIV also decreased mortality compared to no NIV in patient groups, which did not exclude patients with COPD (OR = 0.25; 95% CI: 0.08-0.74; P = 0.013). The need for intubation was significantly reduced in NIV-treated patients (OR = 0.22; 95% CI: 0.09-0.53; P = 0.001), which effect was more prominent in pneumonia patient groups not excluding patients with pre-existing COPD (OR = 0.13; 95% CI: 0.03-0.46; P = 0.002).NIV markedly decreases the death rate in the intensive care unit and reduces the need for intubation in patients with pneumonia-associated respiratory failure. The beneficial effects of NIV seem more pronounced in populations that include patients with COPD. Our findings suggest that NIV should be considered in the therapeutic guidelines of pneumonia, given that future clinical trials confirm the results of our meta-analysis.All data and materials generated during the current study are available from the corresponding author on reasonable request
