Yersinia spp. are non-spore-forming Gram-negative bacilli. They comprise only three species known to cause disease in humans, namely Y. pestis, Y. enterocolitica and Y. pseudotuberculosis. Since infective endocarditis (IE) is rarely caused by Yersinia, the management of these infections can be problematic due to the lack of experience. The purpose of this study was to systematically review all published cases of IE by Yersinia species in the literature. A systematic review of PubMed, Scopus and Cochrane Library (through 1 November 2020) for studies providing epidemiological, clinical and microbiological information as well as data on treatment and outcomes of IE caused by Yersinia species was performed. A total of 12 studies, containing data of 12 patients, were included. A prosthetic valve was present in 17% of patients. The mitral valve was the most commonly infected site, followed by the aortic valve. Fever, sepsis and embolic phenomena were common clinical signs, followed by heart failure. Aminoglycosides, cephalosporins and quinolones were the most commonly used antimicrobials. Clinical cure was noted in 83%, while overall mortality was 17%. This systematic review describes IE by Yersinia and provides information on patients’ epidemiology, clinical signs and the related therapeutic strategies and outcomes.

Infective Endocarditis (IE) is associated with significant mortality. Interestingly, IE in patients with liver transplantation has not been adequately described. The aim of this review was to systematically review all published cases of IE in liver transplant recipients and describe their epidemiology, microbiology, clinical characteristics, treatment and outcomes. A systematic review of PubMed, Scopus and Cochrane Library (through 2nd January 2021) for studies providing epidemiological, clinical, microbiological, treatment data and outcomes of IE in liver transplant recipients was conducted. A total of 39 studies, containing data for 62 patients, were included in the analysis. The most common causative pathogens were gram-positive microorganisms in 69.4%, fungi in 25.8%, and gram-negative microorganisms in 9.7% of cases, while in 9.3% IE was culture-negative. The aortic valve was the most commonly infected valve followed by mitral, tricuspid and the pulmonary valve. Aminoglycosides, vancomycin and aminopenicillins were the most commonly used antimicrobials, and surgical management was performed in half of the cases. Clinical cure was noted in 57.4%, while overall mortality was 43.5%. To conclude, this systematic review thoroughly describes IE in liver transplant recipients and provides information on epidemiology, clinical presentation, treatment and outcomes.

Abstract Background: Extracorporeal membrane oxygenation (ECMO) has been increasingly used for severe neonatal respiratory failure refractory to conventional treatments. To systematically evaluate the complications and mortality of venovenous ECMO in the treatment of neonatal respiratory failure, we performed a systematic review and meta-analysis of all the related studies. Methods: PubMed, Embase, and Cochrane Library were searched. The retrieval period was from the establishment of the database to February 2019. Two investigators independently screened articles according to the inclusion and exclusion criteria. The quality of article was assessed by the Newcastle-Ottawa scale (NOS). The meta-analysis was performed by Stata 15.0 software. Results: Four observational studies were included, with a total of 347 newborns. The overall mortality at hospital charge was 12% (5% - 18%) with a heterogeneity of I2 = 73.8% (p = 0.01). Two studies reported mortality during ECMO and after decannulation, with 10% (0.8% -19.2%) and 6.1% (2.6% - 9.6%) respectively. The most common complications associated with venovenous ECMO were: pneumothorax (20.6%), hypertension (20.4%), cannula dysfunction (20.2%), seizure (14.9%), renal failure requiring hemofiltration (14.7%), infectious complications (10.3%), thrombi (7.4%), intracranial hemorrhage or infarction (6.6%), hemolysis (5.3%), cannula site bleeding (4.4%), gastrointestinal bleeding (3.7%), oxygenator failure (2.8%), other bleeding events (2.8%), brain death (1.9%), and myocardial stun (0.9%). Conclusion: The overall mortality at discharge of venovenous ECMO in the treatment of neonatal respiratory failure was 12%. Although complications are frequent, the survival rate during hospitalization is still high. Further larger samples and higher quality of randomized controlled trials (RCT) are needed to clarify the efficacy and safety of this technique in the treatment of neonatal respiratory failure.

Abstract Background: Extracorporeal membrane oxygenation (ECMO) has been increasingly used for severe neonatal respiratory failure refractory to conventional treatments. To systematically evaluate the complications and mortality of venovenous ECMO (VV ECMO) in the treatment of neonatal respiratory failure, we performed a systematic review and meta-analysis of all the related studies. Methods: PubMed, Embase, and Cochrane Library were searched. The retrieval period was from the establishment of the database to February 2019. Two investigators independently screened articles according to the inclusion and exclusion criteria. The quality of article was assessed by the Newcastle-Ottawa scale (NOS). The meta-analysis was performed by Stata 15.0 software. Results: Four observational studies were included, with a total of 347 newborns. VV ECMO was used for neonates with refractory respiratory failure unresponsive to maximal medical therapy. Median ages of the newborns at cannulation were 43.2 hours, 23 hours, 19hours, and 71 hours in the included four studies, respectively. The overall mortality at hospital charge was 12% (5%-18%) with a heterogeneity of I 2 =73.8% (p=0.01). Two studies reported mortality during ECMO and after decannulation, with 10% (0.8%-19.2%) and 6.1% (2.6%-9.6%), respectively. The most common complications associated with VV ECMO were: pneumothorax (20.6%), hypertension (20.4%), cannula dysfunction (20.2%), seizure (14.9%), renal failure requiring hemofiltration (14.7%), infectious complications (10.3%), thrombi (7.4%), intracranial hemorrhage or infarction (6.6%), hemolysis (5.3%), cannula site bleeding (4.4%), gastrointestinal bleeding (3.7%), oxygenator failure (2.8%), other bleeding events (2.8%), brain death (1.9%), and myocardial stun (0.9%).

This systematic review aims to provide an overview of the diagnostic methods, preventive strategies, and therapeutic approaches for cyclists suffering from pudendal neuropathy. The study defines a guide in delineating a diagnostic and therapeutic protocol using the best current strategies. Pubmed, EMBASE, the Cochrane Library, and Scopus Web of Science were searched for the terms: “Bicycling” OR “Bike” OR “Cyclists” AND “Neuropathy” OR “Pudendal Nerve” OR “Pudendal Neuralgia” OR “Perineum”. The database search identified 14,602 articles. After the titles and abstracts were screened, two independent reviewers analyzed 41 full texts. A total of 15 articles were considered eligible for inclusion. Methodology and results of the study were critically appraised in conformity with PRISMA guidelines and PICOS criteria. Fifteen articles were included in the systematic review and were used to describe the main methods used for measuring the severity of pudendal neuropathy and the preventive and therapeutic strategies for nerve impairment. Future research should determine the validity and the effectiveness of diagnostic and therapeutic strategies, their cost-effectiveness, and the adherences of the sportsmen to the treatment.

Brachial mycotic pseudoaneurysms (BMPA) are a rare complication of infective endocarditis (IE), but potentially could be a limb-threatening condition. We present the case of a 38-year-old male referred to our department, complaining of the sudden onset of a painful pulsatile mass 5 x 10 cm in the right antecubital fossa that slowly progressed over time. Two years before this, he underwent aortic and mitral valve replacement with mechanical prosthetic valves and tricuspid annuloplasty for IE with methicillin-susceptible Staphylococcus aureus after a six-week course of intravenous antibiotherapy with oxacillin. Clinical examination of the right upper limb revealed a pulsatile and compressible mass with a normal temperature and without other clinical signs of inflammation. Pulse of the axillary artery, brachial and radial arteries were palpable. He was diagnosed by Doppler ultrasonography and digital subtraction angiography with BMPA. Furthermore, transesophageal echocardiography (TEE) revealed normal function of the aortic and mitral prosthetic valve with no signs of prosthetic valve endocarditis and no feature of congestive heart failure. Considering these clinical findings, surgical treatment was planned. He underwent re-section of the brachial pseudoaneurysm and arterial reconstruction. One year after the pseudoaneurysm resection, evolution was excellent. This manuscript presents this rare, uncommon complication after IE and also reviews the available surgical management strategies for this pathology.

Probiotics have aroused great interest as an adjunctive treatment to periodontal therapy, due to the frequent colonisation by periodontopathogens after therapy. The aim of this systematic review was to analyse in the scientific literature, evidence of the microbiological effects of probiotics as an adjunct to periodontal therapy in the treatment of periodontal diseases (PD). Only randomised controlled trials (RCT), evaluating the microbiological effect of probiotics as an adjunct to periodontal therapy. The authors conducted a search in PubMed/MEDLINE, LILACS, ScienceDirect, Web of Science and Cochrane Library to identify articles published in English until February 2020. The quality of the studies was assessed using the JADAD scale and the risk of bias was assessed according to the Cochrane Collaboration assessment tool. Of the 265 articles potentially relevant to this review, 10 studies were included. The most frequently used probiotic bacteria were those of the genus Lactobacillus spp. and the time of administration of the probiotics was between 14 days to 3 months. Most studies have shown that the adjuvant use of probiotics reduces the total mean counts of gram-negative anaerobic species (Porphyromonas gingivalis, Tannerella forsythia, Treponema denticola and Prevotella intermedia) and gram-negative coccobacillus (Aggregatibacter actinomycetemcomitans) of subgingival plaque samples. Probiotics adjuvant to periodontal therapy reduces periodontopathogenic species in a greater proportion, compared only to periodontal therapy. Especially the Lactobacillus reuteri strain, without combination with other strains, offered a greater reduction in pathogenic bacteria associated with greater destruction of periodontal tissues and deep periodontal pockets. Researchers should perform high-quality RCT, evaluating single strains without combinations, in order to observe the microbiological benefits as adjunctive treatment of PD.

Objective: The aim of this systematic review was to determine whether the smear layer (SL) removal procedure influences the outcome of root canal treatment. Study design: We performed a search on Pubmed, Scopus, ISI Web of Science, Cochrane Library, Lilacs and SIGLE. We included randomized controlled clinical trials (RCT), with clinical and radiographic outcomes, conducted on subjects who had undergone root canal therapy. The protocol differed only in the SL removal or maintenance procedure. We evaluated the papers for risk of bias according to the Cochrane assessment tool. Results: A total of 1,983 articles were found, after removal of duplicates, 892 remained. We included two studies in this review. One study revealed a low risk of bias and a high success rate for the SL removal group compared to the non SL removal group (P = 0.04), while the other study had a high risk of bias and found no difference between the SL removal and non SL removal groups (P = 1.00). Conclusion: We concluded that the SL removal for root canal treatment of primary teeth with initial clinical signs and symptoms or pulpal necrotic status, could benefit the outcome, although further RCT should be performed to achieve evidence.

Abstract Background The effects of thymectomy on late-onset non-thymomatous myasthenia gravis (NTMG) remain controversial. The objective of this study was to conduct a systematic review in order to answer two questions pertinent to late-onset NTMG: (1) do patients with late-onset NTMG experience the same effects from thymectomy as their early-onset counterparts? (2) Compared with conservative treatment, does thymectomy have any benefits for late-onset NTMG patients? Methods We searched the PubMed, EMBASE, and Cochrane Library databases for studies published from January 1, 1950 to March 10, 2021. Outcomes were measured via clinical stable remission/pharmacological remission (CSR/PR) and improvement rates. We used Stata software to analyze the data. Results We ultimately included a total of 12 observational articles representing the best evidence answering the questions of our study objective. Of these, nine studies, which included 896 patients overall (766 early-onset and 230 late-onset), compared postoperative outcomes between early- and late-onset NTMG. The remaining three articles, which included 216 patients (75 in the thymectomy group and 141 in the conservative-treatment group), compared thymectomy with conservative treatment for late-onset NTMG. The early- versus late-onset NTMG studies demonstrated that patients in the former category were 1.95× likelier than their late-onset counterparts to achieve clinical remission (odds ratio [OR] 1.95; 95% confidence interval [CI] 1.39–2.73; I2 = 0%). No difference was seen in improvement or remission + improvement rates between these two groups. When comparing thymectomy with conservative treatments in late-onset NTMG patients, neither did we observe any difference in CSR/PR. Conclusion We found that late-onset NTMG patients had a lower chance of achieving CSR after thymectomy than early-onset patients. Thymectomy in late-onset NTMG also yielded no benefit to CSR or PR compared with conservative treatments. In late-onset NTMG patients, thymectomy should therefore be performed with caution, and the appropriate cutoff between early- and late-onset MG should be further explored in order to tailor and execute the proper therapeutic strategies.

Background: Intensive care patients with nonocclusive mesenteric ischemia (NOMI) show mortality rates of 70% to 90%. Besides emergency surgery, different interventional local vasodilatory treatment (LVT) attempts have been described. We performed a systematic review and a meta-analysis to evaluate feasibility, efficacy, and tolerability of LVT in patients with life-threatening NOMI. Methods: Searches of PubMed, EMBASE, Web of Science, and Cochrane Library databases were performed until February 2019. Measured outcomes included immediate technical success rates (as indicated by mesenteric vasodilation on angiography or clinical improvement) and adverse events (AEs). Therapeutic efficacy was measured by the assessment of overall mortality. Results: Twelve studies (335 patients, 245 received LVT) from 1977 to 2018 were included. All studies were retrospective (4 comparative and 8 noncomparative). Different intra-arterial vasodilators (4× papaverine, 6× prostaglandin E1, 1× tolazoline/heparin, 1× tolazoline + iloprost) were reported. Initial technical success rate was 75.9% (95% confidence interval [CI], 55.1%-89%, P = .017) with an AE rate of 2.9% (95% CI: 1.3%-6.6%; P = .983). Overall mortality in LVT patients was 40.3% (95% CI: 28.7%-53%, P = .134). In 4 studies, outcomes were compared between patients receiving LVT to those who received standard of care (odds ratio for death in LVT patients was 0.261 [95% CI: 0.095-0.712, P = .009]). Conclusions: Local vasodilatory treatment appears to be safe in patients with NOMI and might have the potential to at least partially reverse mesenteric vasoconstriction features in control angiographies. However, with no randomized and prospective studies available yet, the overall quality of published studies has to be considered as low; therefore, it is not possible to draw generalizable conclusions from the present data concerning clinical end points. Its application might hold promise as a rescue treatment strategy and deserves further evaluation in randomized controlled trials.
