Lactobacillus can lead to serious infection in individuals with multiple predisposing factors. Therefore, individuals with risk factors, including steroid use, and those harboring immunocompromised conditions such as hypothyroidism and cancer, should be promptly evaluated and appropriate treatment should be initiated without delay if the culture test is positive for Lactobacillus.

Objective To investigate whether the implementation of a Children’s Hospital in the Home (CHITH) service affects clinical and service outcomes for children with chronic respiratory conditions including cystic fibrosis and non-CF bronchiectasis. Study Design A non-contemporary retrospective cohort comparison study. Setting/Patients Children aged between 1 and 17.99 years who were admitted to Gold Coast University Hospital (GCUH) with a chronic respiratory condition for pulmonary optimisation were eligible. Methods A clinical audit was utilised to compare children with chronic respiratory conditions who were admitted to GCUH in (a) the 12 months prior to implementation of CHITH and (b) the 12-month period following the implementation of CHITH. Outcomes of interest included lung function; inpatient length of stay (days); duration on intravenous antibiotics and weight gain. Normally distributed data was compared using the t-test, while non-parametric data was analysed with the Mann-Whitney test. Results Data was analysed from 58 admissions, 27 (46.55%) of which occurred in the 12 months of traditional management and 31 (53.45%) in the 12 months following the implementation of the CHITH service. A statistically significant reduction in inpatient length of stay was noted following implementation of the CHITH service: 14.25 versus 6.0 days (p-value=0.0001). The pre-CHITH cohort had a non-significant mean improvement of 7.625% in their FEV1 (pred%) compared to 9.75% in the CHITH cohort (p-value=0.44). There was no significant difference in the secondary clinical outcomes. Conclusion The CHITH service provided equitable clinical outcomes for children with a chronic respiratory condition whilst significantly reducing inpatient length of stay.

Inferior epigastric artery pseudoaneurysm is a rare complication following abdominal wall procedures near the artery. This is a case of Inferior epigastric artery pseudoaneurysm after therapeutic paracentesis for large volume ascites caused by chronic kidney failure. The patient was operated on, and the artery was ligated.

Lynch syndrome (LS) is an autosomal dominant hereditary disease, which is caused by mismatch repair (MMR) gene mutations in the germline of MLH1, MSH2, MSH6 and PMS2. LS patients can develop colorectal cancer, endometrial cancer (EC), etc, at the same or different time, so their prognosis are poor.

This clinical image presents an unusual report of simultaneous laparoscopic resection of a hydrocele of the canal of Nuck and an ovarian tumor. Laparoscopic treatment with a proper approach is a useful technique in some cases.

Background: CO2 laser and the 532-nm potassium titanyl phosphate laser (KTP) were developed to treat Laryngeal papillomatosis (LP); however, the difference in their outcomes remains unclear. Methods: A systematic review was conducted through a comprehensive search of three databases. Results: Overall, the cure rates were 87.25% in the KTP group and 75.98% in the CO2 group (p＜0.05). The complications rates were significantly different between the two groups (p<0.0001). In addition, there was no significant difference between the recurrence rates of the CO2 group and the KTP group (10% vs 9.8%). The risks of bias were 13.1±1.45 and 13.6±1.52 for CO2 group and KTP group respectively, which indicated the fair quality of evidence. Conclusions: The available fair-quality evidence suggested that KTP laser excision may be a better choice for LP. Following evaluations on the benefits of the two surgical techniques with more high-quality randomized controlled studies are needed.

This paper reports on the scaling-up of a one-step methanol production process from the laboratory scale to the pilot scale. This lays the foundation for the industrialization of a one-step process for preparing DMM from methanol. After a long period of operation in the circulating fluidized bed, the Fe-Mo/HZSM-5 catalyst was shown to have high stability and carbon deposition resistance, and the regeneration effect of the circulating regeneration fluidized bed was better. In addition, in-situ DRIFTS was used to explore the effects of reaction time, the Mo-Fe ratio and carrier Si-Al ratio on the reaction and product distribution. It was found that the synergistic effect of oxidation centers and acid centers was the fundamental reason for the excellent catalytic performance of the Fe-Mo/HZSM-5 catalyst. And proposed the reaction mechanisms in the one-step synthesis of methylal via methanol oxidation.

Giant Cell Tumor of Bone is an uncommon aggressive benign neoplasm that frequently affecting the epiphysis of long bones especially around the knee. This is a singular rare case of GCTB in the right maxillary sinus implicated in a process coincidentally or casually with another type of lesion primarily developed.

A 56-year-old female with pulmonary Mycobacterium avium complex disease started to inhale of liposomal amikacin. One month later, she developed hoarseness and was diagnosed with laryngitis. The laryngitis healed immediately after discontinuing the treatment, and no recurrence occurred even after resuming intermittent inhalation.

A 68-year-old female was operated for a giant dedifferentiated retroperitoneal liposarcoma (RLS) encasing entirely the right kidney. She had an en-bloc resection of the tumor with right nephrectomy. The en-bloc resection should avoid R1 resection margins. Renal conservation is suggested if the kidney is widely displaced and for elderly patient.

Percutaneous endoscopic gastrostomy (PEG) tube is a common procedure. This discusses the rare complication of acute pancreatitis, due to tube migration, causing obstruction of the ampulla of Vater. Radiological confirmation of tubes prior to usage may aid in preventing this reversible complication.

We study the following coupled fractional Schrödinger system: $$ \bcs (-\De)^s u=\la_1 u+\mu_1|u|^{p-2}u+\beta r_1|u|^{r_1-2}u|v|^{r_2}\quad &\hbox{in}\;\mathbb{R}^N, \\ (-\De)^s v=\la_2 v+\mu_2|v|^{q-2}v+\beta r_2|u|^{r_1}|v|^{r_2-2}v\quad &\hbox{in}\;\mathbb{R}^N, \\ %\int_{\mathbb{R}^N} u^2=a\quad and\quad \int_{\mathbb{R}^N} v^2=b, \ecs $$ with prescribed mass \[ \int_{\mathbb{R}^N} u^2=a\quad \hbox{and}\quad \int_{\mathbb{R}^N} v^2=b. \] Here, $a, b>0$ are prescribed, $N>2s, s>\frac{1}{2}$, $2+\frac{4s}{N}0$ sufficiently large, a mountain pass-type normalized solution exists provided $2\leq N\leq 4s$ and $ 2+\frac{4s}{N}

Objective To study pain symptoms and their correlation with the anatomical location (and extent) of deep endometriosis lesion(s) classified by the Enzian score. Design Prospective multi-centre study Setting Web-based application called EQUSUM (www.equsum.org) to classify and report surgical procedures Population or Sample A total of 419 surgical DE (deep endometriosis) cases Methods Collection of surgical data in DE cases and their endometriosis classification and pain scores. Main Outcome Measures Preoperative reported pain scores in each domain (dysmenorrhea, dyschezia, dysuria, dyspareunia, chronic pelvic pain) were collected along with the Enzian classification. Baseline characteristics, pain scores, surgical procedure and extent of the disease were also collected. Results In general, more extensive involvement of DE does not lead to an increase in numerical rating scale for pain measures. However, dysuria and bladder involvement do show a clear correlation AUC 0.62 (SE 0.04, CI 0.54-0.71, p< 0.01). Regarding the predictive value of dyschezia, we found a weak, but significant correlation with ureteric involvement; AUC 0.60 (SE 0.04, CI 0.53-0.67, p< 0.01). Conclusions Pain symptoms poorly correlate with anatomical locations of deep endometriosis in almost all pain scores, with the exception of bladder involvement and dysuria which did show a correlation. Also dyschezia seems to have predictive value for DE ureteric involvement and therefore MRI or ultrasound imaging (ureter and kidney) is recommended in the preoperative workup in these patients.

Introduction- Markers predicting AF termination and freedom from AF/atrial tachycardia (AT) has been proposed. The role of CS electrogram characteristics has not yet been evaluated. Methods- Patients undergoing ablation for persistent AF as part of the Stochastic Trajectory Analysis of Ranked signals mapping study were included. Novel CS electrogram characteristics including CS cycle length variability (CLV) and CS activation pattern stability (APS) and proportion of low voltage zones (LVZs) were reviewed as potential predictors for AF termination on ablation and freedom from AF/AT during follow-up. The relationship between localized driver characteristics and CS electrogram characteristics were also assessed. Results- Sixty-five patients were included. AF termination was achieved in 51 patients and 80% of patients were free from AF/AT during a follow-up of 29.5±3.7 months. CS CLV of <30ms, CS APS of ≥30% and proportion of LVZ <30% showed a high diagnostic accuracy in predicting AF termination on ablation and freedom from AF/AT during follow-up (CS CLV OR 25.6, AUC 0.91; CS APS OR 15.9, AUC 0.94; proportion of LVZs OR 21.4, AUC 0.88). These markers were independent predictors of AF termination on ablation and AF/AT recurrence during follow-up. Ablation of a smaller number of drivers that demonstrate greater dominance strongly correlate with greater CS organization. Conclusions- Novel CS electrogram characteristics were independent predictors of AF termination and AF/AT recurrence during follow-up. These markers can potentially aid in predicting outcomes and guide ablation and follow-up strategies.

Aim: To evaluate the prognostic utility of red blood cell distribution width (RDW) and left ventricular mass index (LVMI) in patients with hypertrophic cardiomyopathy (HCM). Patients & methods: This study is a retrospective cohort analysis. Patients diagnosed with hypertrophic cardiomyopathy at the First Affiliated Hospital of Sun Yat-sen University from March 2014 to March 2019 were included . HCM patients were stratified into two groups based on the occurrence of major adverse cardiac events (MACE).Receiver operator characteristic (ROC) curves were then constructed and Cox regression models were employed to gauge the prognostic relevance of RDW and LVMI for HCM patients. Kaplan-Meier analysis evaluated the survival and MACE-free rate in patients with different level of RDW and LVMI. Results: A total of 300 patients with HCM were enrolled in this study and followed up for 40.56±18.33 months. Among them, 117 MACE (39.00%), 40 all-cause deaths (13.33%), 29 cardiovascular deaths (9.67%). The level of RDW, LVMI, creatinine (Cr) and B-type pro-brain natriuretic peptide (NT-ProBNP) were statistically different between the MACE group and Non-MACE group ( P<0.05). Multivariate analysis showed that after adjusting for confounding factors, RDW and LVMI were independent predictors of all-cause mortality and MACE in HCM patients. ROC showed that RDW>0.13 and LVMI>181g/m 2 are the cut-off value to predict all-cause mortality and MACE. The AUC of the combination predicting the occurrence of all-cause mortality and MACE are 0.890 and 0.885 respectively. Kaplan-Meier analysis showed that the survival rate and MACE-free survival rate of group 1 (RDW≦0.13 and LVMI≦181g/m 2) were significantly higher than group 2 (RDW>0.13 or LVMI>181g/m 2), and group 3 (RDW >0.13 and LVMI>181g/m 2) ( P=0.000). Conclusion: We determined that increased RDW and LVMI was independently associated with MACE incidence and risk of mortality in HCM patients. Combined evaluation of RDW and LVMI yielded a more accurate predictive model of HCM patient outcomes relative to the use of either of these metrics in isolation. Our research can provide a theoretical basis in the occurrence of MACE for the high-risk HCM and intervene them properly and timely.

Background: Foreign body aspiration (FBA) in the tracheobronchial tree is a common problem in the pediatric population. Rigid bronchoscopic procedure is currently the gold standard method for treatment in pediatric patients, whereas recent reports present flexible bronchoscopy as an alternative method. The aim of this study was to summarize all available evidence regarding the application and the success rate of flexible bronchoscopy in foreign body (FB) removal. Methods: Systematic review of the use of flexible bronchoscopy as the first-line treatment in FBA cases in PubMed from 2001 to 2021. Results: Out of 243 citations, 23 studies were included on the use of flexible bronchoscopic procedure as a treatment of choice in 2,587 children with FBA. The FBs were successfully removed in 2,254/2,587 (87.1%) patients with a low complication rate. The majority of FBs retrieved were organic materials 1,073/1,370 (78.3%), and they were most commonly lodged in the right bronchial tree 708/1,401 (50.5%). General anesthesia was applied in most studies (14/23) before proceeding to a flexible bronchoscopy and laryngeal mask airways (LMAs) were mostly used (10/23 studies) to secure the airway during the procedure. Ancillary equipment, usually forceps 1,544/1808 (85.4%) assisted in the FB retrieval. Conclusion: The use of flexible bronchoscopy is shown to be a feasible and safe alternative therapeutic procedure in FBA cases. There is a need for development of extraction equipment and techniques to assist the procedure. Finally, future studies focusing on the comparison between clinical outcomes of flexible and rigid bronchoscopies are necessary.

Background: Tetralogy of Fallot (TOF) is the most common combined the deformity of unilateral absence of the pulmonary artery (UAPA). The treatment strategy of TOF combined with UAPA is still very controversial. In this study, we analyzed the effect of the bilateral pulmonary reconstruction for patients with TOF combined with UAPA. Methods: A single-institution, retrospective review of all 1713 patients with TOF between January 2009 to November 2021. Eight patients were diagnosed with TOF combined with UAPA, and 7 patients underwent the surgery. Three patients underwent one-stage TOF correction with bilateral pulmonary artery reconstruction. Three patients underwent bilateral pulmonary artery reconstruction, followed by two-stage TOF correction after several months. One patient underwent 2 procedures of left pulmonary artery reconstruction, and the VSD remained open. Results: All 7 patients survived during the postoperative follow-up and showed good cardiac function and normal oxygen saturation >97%. During the follow-up with echocardiograms, it was found that the left pulmonary arteries that were reconstructed with Goretex vessel or direct anastomosis had thrombosis or stenosis. The left pulmonary artery reconstructed with the modified autologous tissue extension technique was unobstructed. Conclusions: In patients with TOF and UAPA, if there is a pulmonary confluence in the affected hilum, it is feasible to implement bilateral pulmonary artery reconstruction for one-stage TOF correction. The use of pulmonary artery extension technique and autologous tissue to bilateral pulmonary reconstruct could reduce the incidence of anastomotic stenosis.

Robotic totally endoscopic techniques to perform the LITA to LAD graft, coupled with PCI, provides the least invasive option to achieve hybrid coronary revascularization (HCR). Shorter hospital stay and reduced need for blood transfusions have been consistently being reported by several studies along with similar long-term outcomes. Considerable variations exist in the definition of HCR which can be single or two-staged with surgical revascularization being carried out after PCI or vice versa. Variations also exist with respect to usage of cardiopulmonary bypass, surgical incisions, and use of minimally invasive robotic techniques. The different strategies of HCR do not lead to similar outcomes and the findings of one strategy cannot be extrapolated to the entire group. Studies reporting different strategies of HCR, should ideally provide more granular data when reporting outcomes.

Patients with a bicuspid aortic valve (BAV) are at increased risk of valvular regurgitation compared to their counterparts with a tri-leaflet aortic valve. There is now increasing emphasis to offer BAV repair to mitigate the risks of prosthesis-related complications, including thromboembolism, haemorrhage and endocarditis, as well as structural valve deterioration and future re-operation with conventional valve replacement, particularly in younger populations. Furthermore, over the preceding two decades, our greater understanding of the functional anatomy of the BAV, pathophysiological mechanisms of BAV insufficiency and the development of a functional classification of aortic regurgitation have significantly contributed to the evolution of aortic valve reconstructive surgery. In this commentary, we discuss a recent article from the Journal of Cardiac Surgery comparing external annuloplasty and subcommissural annuloplasty as techniques for BAV repair.

Multisystemic Inflammatory Syndrome in Children (MIS-C) has emerged as a challenging entity during the COVID-19 era. Here, we present the first case of MIS-C comprised of acute appendicitis and myocarditis in Iran. Unfortunately, the diagnosis was made late, and the patient died following an appendectomy and extensive fluid therapy.

The fractional derivatives are not equal for different expressions of the same piecewise function, which caused that the equivalent integral equations of impulsive fractional order system (IFrOS) proposed in existing papers are incorrect. Thus we reconsider two generalized IFrOSs that both have the corresponding impulsive Caputo fractional order system and the corresponding impulsive Riemann-Liouville fractional order system as their special cases, and discover that their equivalent integral equations are two integral equations with some arbitrary constants, which reveal the non-uniqueness of solution of the two generalized IFrOSs. Finally, two numerical examples are offered for explaining the non-uniqueness of solution to the two generalized IFrOSs.

We focus on a new type of nonlinear integro-differential equations with nonlocal integral conditions. The considered problem has one nonlinearity with time variable singularity. It involves also some convergent series combined to Riemann-Liouville integrals. We prove a uniqueness of solutions for the proposed problem, then, we provide some examples to illustrate this result. Also, we discuss the Ulam-Hyers stability for the problem. Some numerical simulations, using Rung Kutta method, are discussed too. At the end, a conclusion follows.

We investigate the fractional order love dynamic model with time delay for synergic couples in this manuscript. The quantitative analysis of the model has been done where the asymptotic stability of the equilibrium points of the model have been analyzed. Under the impact of time delay, the Hopf bifurcation analysis of the model has been done. The stability analysis of the model has been studied with the reproduction number less than or greater than 1. By using Laplace transformation, the analysis of the model has been done. The analysis shows that the fractional order model with a time delay can sufficiently improve the components and invigorate the outcomes for either stable or unstable criteria. In this model, all unstable cases are converted to stable cases under neighbourhood points. For all parameters, the reproduction ranges have been described. Finally, to illustrate our derived results numerical simulations have been carried out by using MATLAB. Under the theoretical outcomes from parameter estimation, the love dynamical system is verified.

In this paper, we study the long-time dynamical behavior of the non-autonomous velocity-vorticity-Voigt model of the 3D Navier-Stokes equations with damping and memory. We first investigate the existence and uniqueness of weak solutions to the initial boundary value problem for above-mentioned model. Next, we prove the existence of uniform attractor of this problem, where the time-dependent forcing term $f \in L^2_b(\mathbb{R}; H^{-1}(\Omega))$ is only translation bounded instead of translation compact. The results in this paper will extend and improve some results in Yue, Wang (Comput. Math. Appl., 2020) in the case of non-autonomous and contain memory kernels which have not been studied before.
