Minimal Clinically Important Differences (MCID) for the Functional Assessment of Chronic Illness Therapy Fatigue Scale in Patients with Systemic Sclerosis

(1) Background: Systemic sclerosis (SSc) is characterized by significant fatigue, causing diminished quality of life (QoL). The aim of this study was to examine fatigue levels and their associations with clinical factors and determine the minimal clinically important difference (MCID) value for the Functional Assessment of Chronic Illness Therapy Fatigue Scale (FACIT-FS). (2) Methods: A total of 160 SSc patients and 62 individuals without SSc were followed-up over a 12-month period by measuring the FACIT-FS and the Visual Analogue Scale and the Short Form 36 Vitality Score analyzing changes in exhaustion. (3) Results: Fatigue was strongly correlated with HRQoL, level of pain, emotional disorders, physical capability and functionality. The MCID values for FACIT-FS were calculated as -3 for deterioration and +4 for improvement after a 12-month follow-up. The predictors of improvement of fatigue from baseline parameters were the significant disease activity, the patients' poorer functionality and the short disease duration. Patients with scleroderma-related interstitial lung disease at baseline had approximately tripled risks for worsening fatigue. The independent influential factors regarding the changing of FACIT-FS were improving or worsening in the same direction in reference to physical condition, gastrointestinal and emotional factors. (4) Conclusions: Fatigue is a multi-dimensional symptom, which is strongly correlated to HRQoL. MCID values of FACIT-FS can be useful tools in monitoring the changes of HRQoL in clinical trials and in daily practice among patients with SSc.

The risk of postoperative respiratory complications following adenotonsillar surgery in children with or without obstructive sleep apnea: A systematic review and meta-analysis

OBJECTIVES

Obstructive sleep apnea (OSA) appears in 2%-5% of children, with first-line treatment being adenotonsillar (AT) surgery. Our aim was to examine the risk of postoperative respiratory complications (PoRCs) in non-OSA and the different OSA severity (mild, moderate, severe) groups.

STUDY DESIGN

We conducted a systematic review and meta-analysis of studies comparing PoRCs following AT surgery in children with and without OSA.

METHODS

Nineteen observational studies were identified with the same search key used in MEDLINE, Embase, and CENTRAL. The connection between PoRCs, the presence and severity of OSA, and additional comorbidities were examined. Odds ratios (OR) were calculated with 95% confidence intervals (CI).

RESULTS

We found that PoRCs appeared more frequently in moderate (p = 0.048, OR: 1.79, CI [1.004, 3.194]) and severe OSA (p = 0.002, OR: 4.06, CI [1.68, 9.81]) compared to non-OSA patients. No significant difference was detected in the appearance of major complications (p = 0.200, OR: 2.14, CI [0.67, 6.86]) comparing OSA and non-OSA populations. No significant difference was observed in comorbidities (p = 0.669, OR: 1.29, CI [0.40, 4.14]) or in the distribution of PoRCs (p = 0.904, OR: 0.94, CI [0.36, 2.45]) between the two groups.

CONCLUSION

Uniform guidelines and a revision of postoperative monitoring are called for as children with moderate and severe OSA are more likely to develop PoRCs following AT surgery based on our results, but no significant difference was found in mild OSA. Furthermore, the presence of OSA alone is not associated with an increased risk of developing major complications.

Inflammatory bowel disease does not alter the clinical features and the management of acute pancreatitis: A prospective, multicentre, exact-matched cohort analysis

OBJECTIVE AND AIMS

Acute pancreatitis in inflammatory bowel disease occurs mainly as an extraintestinal manifestation or a side effect of medications. We aimed to investigate the prognostic factors and severity indicators of acute pancreatitis and the treatment of patients with both diseases.

DESIGN

We performed a matched case-control registry analysis of a multicentre, prospective, international acute pancreatitis registry. Patients with both diseases were matched to patients with acute pancreatitis only in a 1:3 ratio by age and gender. Subgroup analyses were also carried out based on disease type, activity, and treatment of inflammatory bowel disease.

RESULTS

No difference in prognostic factors (laboratory parameters, bedside index of severity in acute pancreatitis, imaging results) and outcomes of acute pancreatitis (length of hospitalization, severity, and local or systemic complications) were detected between groups. Significantly lower analgesic use was observed in the inflammatory bowel disease population. Antibiotic use during acute pancreatitis was significantly more common in the immunosuppressed group than in the non-immunosuppressed group (p = 0.017). However, none of the prognostic parameters or the severity indicators showed a significant difference between any subgroup of patients with inflammatory bowel disease.

CONCLUSION

No significant differences in the prognosis and severity of acute pancreatitis could be detected between patients with both diseases and with pancreatitis only. The need for different acute pancreatitis management is not justified in the coexistence of inflammatory bowel disease, and antibiotic overuse should be avoided.

Geno- and phenotypic characteristics and clinical outcomes of CACNA1C gene mutation associated Timothy syndrome, “cardiac only” Timothy syndrome and isolated long QT syndrome 8: A systematic review

Background

Mutations in the CACNA1C gene–encoding for the major Ca2+ channel of the heart–may exhibit a variety of clinical manifestations. These include typical or atypical Timothy syndromes (TS) which are associated with multiple organ manifestations, and cardiac involvement in form of malignant arrhythmias, QTc prolongation, or AV block. “Cardiac only” Timothy syndrome (COTS) shows no extracardiac manifestation, whereas some CACNA1C gene mutations are associated with QTc prolongation alone (isolated long QT syndrome 8, LQT8).

Methods

A systematic search of the literature reporting cases of CACNA1C gene mutation associated syndromes, including TS, COTS and isolated LQT8 via major databases published from 2004 through 2019 was performed. Detailed patient-level phenotypic and genotypic characteristics, as well as long-term outcome measures were collected and compared between pre-specified patient groups, defined both on phenotype and genotype.

Results

A total of 59 TS, 6 COTS, and 20 isolated LQT8 index cases were identified. Apart of syndactyly or baldness, there were no major differences regarding clinical manifestations or outcome measures between TS subtypes, either defining TS subtypes on the genotype or based on the phenotype. Both subtypes were characterized by an extreme degree of QTc prolongation (median ≥600 ms) which were reflected in high major adverse cardiac event rate. On the other hand, there were marked differences between TS, COTS, and isolated LQT8. Timothy syndrome was characterized by a much earlier disease onset, much more pronounced QTc prolongation and much higher mortality rate than COTS or isolated LQT8. Similar differences were observed comparing CACNA1C exon 8/8A vs. non-exon 8/8A mutation carriers. TS showed a high degree of genetic homogeneity, as the p.Gly406Arg mutation either in exon 8 or exon 8A alone was responsible for 70% of the cases.

Conclusions

Clinical phenotypes associated with mutations in the CACNA1C gene show important clinical differences. Timothy syndrome is associated with the most severe clinical phenotype and with the highest risk of morbidity and mortality. However, distinguishing TS subtypes, in any form, are not supported by our data.

Increased arterial stiffness predict major adverse cardiovascular events in post-infarcted patients. Do parameters and methods matter?

Introduction

According to recent 2021 ESC prevention guidelines arterial stiffness (aortic pulse wave velocity – PWV, augmentation index - Aix) predicts future major adverse cardiovascular events (MACE). Both parameters have a prognostic relevance, however due to the various technical approaches the level of high stiffness values show significant differences and resulting an argue against widespread use.

Purpose

We evaluated the cut-off PWV and Aix values for MACE prediction using cardiac magnetic resonance imaging (CMR) and oscillometric methods for validating the prognostic value of high stiffness parameters in post-infarcted patients.

Methods

CMR phase contrast imaging (Siemens Avanto, 1,5 T CMR device) and an invasively validated oscillometric based Arteriograph (AG) method were compared in this 6 years follow-up study, including 49 patients suffered previous ST-elevation myocardial infarction (STEMI). Patients received follow-up for MACE comprising all-cause death, non-fatal MI, ischemic stroke, hospitalization for heart failure and coronary revascularization.

Results

49 patients (37 male, average age: 57±8 years) were investigated. An acceptable agreement and significant correlation (Spearman's rho: 0.332, p<0,01) was found between AG and CMR derived PWV values. Bland Altman plot was created to test for methods' agreement. The bias showed that in general the mean difference between the two measures was 3.6 m/s (upper and lower limit of agreement: –0.2 and 7.5 m/s). The coefficient of variation was 43.9%. Totally 51 MACE events occurred during the 6 years follow-up period. Hospitalisation for coronary revascularisation (55%), all-cause death (15%), non-fatal MI (12%), heart failure (12%) exposed the majority of MACE events. Optimized PWV and Aix cut-off values for MACE prediction were calculated (PWVCMR: 6,47 m/s; PWVAG: 9,625 m/s; AixAG: 34,22%) by receiver operating characteristic analysis (Figure 1). Kaplan-Meier analysis in all parameters showed a significantly lower event-free survival in case of high PWV and Aix values (Figure 2). Multivariate Cox regression analysis revealed PWV and Aix as a predictor of MACE (PWVCMR hazard ratio (HR): 1.31 (CI: 1.1–1.7), PWVAG HR: 1.24 (CI: 1.0–1.5), AixAG HR: 1,043 (CI: 1,01–1,08), p<0,05 respectively).

Conclusions

Arterial stiffness, particularly elevated PWV predicts MACE in postinfarcted patients. Our study showed both CMR and oscillometric techniques are feasible for MACE prediction, however, adjusted cut-off values of PWV are recommended for different methods to improve individual risk stratification. All these findings emphasize the clinical relevance for the future measurement of arterial stiffness might contribute to improved risk stratification after MI, which is crucial for the assessment of prognosis and guidance of secondary prevention treatment.

Pancreatic family history does not predict disease progression but connotes alcohol consumption in adolescents and young adults with acute pancreatitis: Analysis of an international cohort of 2,335 patients

Background

In pediatric acute pancreatitis (AP), a family history of pancreatic diseases is prognostic for earlier onset of recurrent AP (ARP) and chronic pancreatitis (CP). No evidence supports the same association in adult-onset pancreatitis. Age-specific reasons for familial aggregation are also unclear. We aimed to examine the prognostic role of pancreatic family history for ARP/CP and observe possible underlying mechanisms.

Methods

We conducted a secondary analysis of the Hungarian Pancreatic Study Group’s (HPSG) multicenter, international, prospective registry of patients with AP, both children and adults. We compared the positive family history and the negative family history of pancreatic diseases, in different age groups, and analyzed trends of accompanying factors. Chi-square and Fisher exact tests were used.

Results

We found a higher rate of ARP/CP in the positive pancreatic family history group (33.7 vs. 25.9%, p = 0.018), peaking at 6–17 years. Idiopathic AP peaked in childhood in the positive family history group (75% 0–5 years) and was consistently 20–35% in the negative group. A higher rate of alcohol consumption/smoking was found in the positive groups at 12–17 years (62.5 vs. 15.8%, p = 0.013) and 18–29 years (90.9 vs. 58.1%, p = 0.049). The prevalence of diabetes and hyperlipidemia steadily rose with age in both groups.

Conclusion

Positive family history most likely signifies genetic background in early childhood. During adolescence and early adulthood, alcohol consumption and smoking emerge—clinicians should be aware and turn to intervention in such cases. Contrary to current viewpoints, positive pancreatic family history is not a prognostic factor for ARP and CP in adults, so it should not be regarded that way.

90Y-ibritumomab Tiuxetan in B-cell Non-Hodgkin Lymphomas: Real-world Data From the United Arab Emirates

Purpose

B-cell non-Hodgkin lymphomas (NHLs) are significant contributors to cancer-related mortality. In this single-arm, retrospective cohort study, we aimed to examine the outcomes of a radioimmunotherapeutic modality, ⁹⁰Y-labeled ibritumomab tiuxetan (⁹⁰YIT) in B-cell NHLs.

Methods and Materials

We conducted this study based on data from the United Arab Emirates lymphoma registry. All patients with NHL subjected to ⁹⁰YIT were eligible for inclusion. The country of research lacked a national autologous stem cell transplantation (ASCT) center, but many ASCT-eligible patients received ⁹⁰YIT. We investigated overall survival (OS) and event-free survival (EFS), as well as safety outcomes.

Results

Between 2004 and 2008, 54 of 111 patients with B-cell NHL received radioimmunotherapy. The therapy was applied as first-line treatment in 18 cases (33.3%) and second- or later-line treatment in 36 cases (66.7%). All patients were evaluable for response. The first-line group consisted mainly of follicular lymphoma cases, and 3 of 18 patients died (16.7%) during the follow-up (range, 22-67 months). Median OS was not reached. No progression occurred after treatment (median EFS, 36.5 months [Q₁-Q₃ range, 30.5-44 months]). The second- or later-line group consisted mainly of diffuse large B-cell lymphoma cases, and 3 of 36 patients died (8.3%) during the follow-up (range, 4-68 months). Median OS was not reached. One case of progression was registered (median EFS: 33 months [Q₁-Q₃ range, 30.5-44 months]). ⁹⁰YIT had acceptable short- and long-term safety profiles.

Conclusions

The findings suggest that patients with NHL may benefit from ⁹⁰YIT as salvage treatment if ASCT is not available; however, this should be validated in randomized studies.

Network meta-analysis of randomized controlled trials on esophagectomies in esophageal cancer: The superiority of minimally invasive surgery

BACKGROUND

Previous meta-analyses, with many limitations, have described the beneficial nature of minimal invasive procedures.

AIM

To compare all modalities of esophagectomies to each other from the results of randomized controlled trials (RCTs) in a network meta-analysis (NMA).

METHODS

We conducted a systematic search of the MEDLINE, EMBASE, Reference Citation Analysis (https://www.referencecitationanalysis.com/) and CENTRAL databases to identify RCTs according to the following population, intervention, control, outcome (commonly known as PICO): P: Patients with resectable esophageal cancer; I/C: Transthoracic, transhiatal, minimally invasive (thoracolaparoscopic), hybrid, and robot-assisted esophagectomy; O: Survival, total adverse events, adverse events in subgroups, length of hospital stay, and blood loss. We used the Bayesian approach and the random effects model. We presented the geometry of the network, results with probabilistic statements, estimated intervention effects and their 95% confidence interval (CI), and the surface under the cumulative ranking curve to rank the interventions.

RESULTS

We included 11 studies in our analysis. We found a significant difference in postoperative pulmonary infection, which favored the minimally invasive intervention compared to transthoracic surgery (risk ratio 0.49; 95%CI: 0.23 to 0.99). The operation time was significantly shorter for the transhiatal approach compared to transthoracic surgery (mean difference -85 min; 95%CI: -150 to -29), hybrid intervention (mean difference -98 min; 95%CI: -190 to -9.4), minimally invasive technique (mean difference -130 min; 95%CI: -210 to -50), and robot-assisted esophagectomy (mean difference -150 min; 95%CI: -240 to -53). Other comparisons did not yield significant differences.

CONCLUSION

Based on our results, the implication of minimally invasive esophagectomy should be favored.

O013 The increasing burden of the two-week wait colorectal cancer pathway within a single centre

Introduction

Increasing demand has placed colorectal cancer (CRC) two-week wait (TWW) pathways under pressure. The primary aims of this paper are to review TWW referral numbers and CRC diagnoses within our centre over the past 3 years (before, during and in recovery from the COVID-19 pandemic) and compare outcomes to our previously published data (2009–18). This incorporates the introduction of FIT into our clinical practice.

Methods

TWW CRC referral data from 1st July 2018–31st July 2021 was analysed. Parameters assessed; monthly TWW referrals, CRC detection, % of TWW referrals seen <14 days and investigations utilised. Data from January 2009 to 31 June 2018 was combined. Unpaired t-test was used to compare group means.

Results

TWW referrals have increased 360% from 2009 to 2020. The proportion of TWW referrals with CRC has decreased from 8.87% to 3.24% over this period, whilst the incidence of CRC remained static (mean 58.7 per annum). From 2009–18, TWW referrals=8921, CRC diagnoses=533, mean monthly CRC detection rate=4.7, ratio of referrals to CRC=16.7:1. From 2018–21, TWW referrals= 6523, CRC diagnoses=232, mean monthly CRC detection rate=6.3, ratio of referrals to CRC=28.4:1. There was a statistically significant difference in mean monthly referrals (p-value<0.00001) between the two periods.

Conclusion

Despite ever-increasing TWW referral numbers, no significant change in CRC diagnoses has occurred. We find our service under ever-increasing strain. Additional strategies and guidance are required to help address this. Further studies evaluating FIT and repeat FIT in the symptomatic TWW cohort may have a role in generating such a consensus.

Take-home message

Two week wait colorectal cancer referrals have increased 360% in 12 years. Colorectal cancer detection rate remains static over this timeframe.

Effect of HEAT therapy in patiEnts with type 2 Diabetes mellitus (HEATED): protocol for a randomised controlled trial

INTRODUCTION

The burden of type 2 diabetes mellitus (T2DM) is increasing worldwide. Heat therapy has been found effective in improving glycaemic control. However, to date, there is a lack of randomised controlled studies investigating the efficacy of heat therapy in T2DM. Therefore, we aim to investigate whether heat therapy with natural thermal mineral water can improve glycaemic control in patients with T2DM.

METHODS AND ANALYSIS

The HEAT therapy in patiEnts with type 2 Diabetes mellitus (HEATED) Study is a single-centre, two-arm randomised controlled trial being conducted at Harkány Thermal Rehabilitation Centre in Hungary. Patients with T2DM will be randomly assigned to group A (bath sessions in 38°C natural thermal mineral water) and group B (baths in thermoneutral water (30°C-32°C)). Both groups will complete a maximum of 5 weekly visits, averaging 50-60 visits over the 12-week study. Each session will last 30 min, with a physical check-up before the bath. At baseline, patients' T2DM status will be investigated thoroughly. Possible microvascular and macrovascular complications of T2DM will be assessed with physical and laboratory examinations. The short form-36 questionnaire will assess the quality of life. Patients will also be evaluated at weeks 4, 8 and 12. The primary endpoint will be the change of glycated haemoglobin from baseline to week 12. An estimated 65 patients will be enrolled per group, with a sample size re-estimation at the enrolment of 50% of the calculated sample size.

ETHICS AND DISSEMINATION

The study has been approved by the Scientific and Research Ethics Committee of the Hungarian Medical Research Council (818-2/2022/EÜIG). Written informed consent is required from all participants. We will disseminate our results to the medical community and will publish our results in peer-reviewed journals.

EASY-APP: An artificial intelligence model and application for early and easy prediction of severity in acute pancreatitis

Background

Acute pancreatitis (AP) is a potentially severe or even fatal inflammation of the pancreas. Early identification of patients at high risk for developing a severe course of the disease is crucial for preventing organ failure and death. Most of the former predictive scores require many parameters or at least 24 h to predict the severity; therefore, the early therapeutic window is often missed.

Methods

The early achievable severity index (EASY) is a multicentre, multinational, prospective and observational study (ISRCTN10525246). The predictions were made using machine learning models. We used the scikit‐learn, xgboost and catboost Python packages for modelling. We evaluated our models using fourfold cross‐validation, and the receiver operating characteristic (ROC) curve, the area under the ROC curve (AUC), and accuracy metrics were calculated on the union of the test sets of the cross‐validation. The most critical factors and their contribution to the prediction were identified using a modern tool of explainable artificial intelligence called SHapley Additive exPlanations (SHAP).

Results

The prediction model was based on an international cohort of 1184 patients and a validation cohort of 3543 patients. The best performing model was an XGBoost classifier with an average AUC score of 0.81 ± 0.033 and an accuracy of 89.1%, and the model improved with experience. The six most influential features were the respiratory rate, body temperature, abdominal muscular reflex, gender, age and glucose level. Using the XGBoost machine learning algorithm for prediction, the SHAP values for the explanation and the bootstrapping method to estimate confidence, we developed a free and easy‐to‐use web application in the Streamlit Python‐based framework (http://easy‐app.org/).

Conclusions

The EASY prediction score is a practical tool for identifying patients at high risk for severe AP within hours of hospital admission. The web application is available for clinicians and contributes to the improvement of the model.

End-range Maitland mobilization decreasing pain sensitivity in knee osteoarthritis: randomized, controlled clinical trial

BACKGROUND

Pressure pain threshold (PPT) is a widely applied method for measuring the magnitude of increased peripheral and central pain sensitivity causing hyperalgesia in knee osteoarthritis (OA). Although manual therapy techniques effects positively PPT, the effect of end-range Maitland mobilization has not been evaluated in knee OA.

AIM

The aim of this study was to investigate the effect of end-range Maitland mobilization compared to sham manual therapy technique on PPT and function-related measures.

DESIGN

The design of the study was of a randomized, controlled clinical trial.

SETTING

Outpatient setting.

POPULATION

Forty women with moderate-to-severe knee OA.

METHODS

Twenty patients (N.=20) were randomly assigned to Maitland group (MG) and twenty patients (N.=20) to control group (CG). Patients in MG received single end-range Maitland mobilization while patients in CG received sham manual therapy technique. Assessment was performed at baseline, 30 minutes and after 1-week period. Outcome measures were PPT locally at knee and distant at ipsilateral extensor carpi radialis longus muscle, general pain during the previous week using the Visual Analogue Scale (VAS), Timed Up and Go Test (TUG) time associated with pain measured with Numerating Pain Rating Scale (NPRS) and strength of passive resistance of knee at onset of pain.

RESULTS

Despite all outcome measures improved significantly postintervention, no changes were detected after 1-week period compared to postintervention in MG. No change of outcome measures was found also postintervention and after 1-week period compared to postintervention in CG. All postintervention results showed significant improvement in between-group comparison in favor of MG. However, after 1-week period, only strength of passive resistance revealed significant difference in between-group comparison in favor of MG (P<0.001).

CONCLUSIONS

Although end-range Maitland mobilization has an immediate effect on decreasing peripheral and central pain sensitivity and improving function-related measures in knee OA, these changes may not cause clinically relevant effect based on data measured after 1-week period.

CLINICAL REHABILITATION IMPACT

Investigating the time-course of end-range Maitland mobilization for determining the optimal treatment frequency during rehabilitation is suggested in knee OA.

Early prediction of acute necrotizing pancreatitis by artificial intelligence: a prospective cohort-analysis of 2387 cases

Pancreatic necrosis is a consistent prognostic factor in acute pancreatitis (AP). However, the clinical scores currently in use are either too complicated or require data that are unavailable on admission or lack sufficient predictive value. We therefore aimed to develop a tool to aid in necrosis prediction. The XGBoost machine learning algorithm processed data from 2387 patients with AP. The confidence of the model was estimated by a bootstrapping method and interpreted via the 10th and the 90th percentiles of the prediction scores. Shapley Additive exPlanations (SHAP) values were calculated to quantify the contribution of each variable provided. Finally, the model was implemented as an online application using the Streamlit Python-based framework. The XGBoost classifier provided an AUC value of 0.757. Glucose, C-reactive protein, alkaline phosphatase, gender and total white blood cell count have the most impact on prediction based on the SHAP values. The relationship between the size of the training dataset and model performance shows that prediction performance can be improved. This study combines necrosis prediction and artificial intelligence. The predictive potential of this model is comparable to the current clinical scoring systems and has several advantages over them.

Preoperative Serum Carbohydrate Antigen 19-9 Levels Cannot Predict the Surgical Resectability of Pancreatic Cancer: A Meta-Analysis

Background and Aims: Pancreatic ductal adenocarcinoma has one of the worst prognosis of all malignancies. This investigated the relationship between the preoperative serum carbohydrate antigen 19-9 and surgical resectability. Methods: A systematic search was performed in three databases (MEDLINE, EMBASE, and Web of Science) to compare the surgical resectability of pancreatic ductal adenocarcinoma in patients with high and low preoperative serum carbohydrate antigen 19-9 values. The receiving operating characteristic curves were constructed and the weighted mean differences for preoperative serum carbohydrate antigen 19-9 levels of resectable and unresectable groups of patients were calculated. The PROSPERO registration number is CRD42019132522. Results: Results showed that there was a significant difference in resectability between the low and high carbohydrate antigen 19-9 groups. Six out of the eight studies utilised receiver operating characteristic curves in order to find the cut-off preoperative carbohydrate antigen 19-9 levels marking unresectability. The overall result from the pooled area under curve values from the receiver operating characteristic curves was 0.794 (CI: 0.694-0.893), showing that the preoperative carbohydrate antigen 19-9 level is a "fair" marker of resectability. The result of the pooled weighted mean differences was 964 U/ml (p < 0.001) showing that there is a significant carbohydrate antigen 19-9 difference between the resectable and unresectable groups. Based on the results of the I-squared test, the result was 87.4%, accounting for "considerable" heterogeneity within the population. Conclusion: Carbohydrate antigen 19-9 is not a reliable marker of unresectability, it should not be used on its own in surgical decision-making.

Goal-Directed Fluid Therapy Enhances Gastrointestinal Recovery after Laparoscopic Surgery: A Systematic Review and Meta-Analysis

(1) Background: Whether goal-directed fluid therapy (GDFT) provides any outcome benefit as compared to non-goal-directed fluid therapy (N-GDFT) in elective abdominal laparoscopic surgery has not been determined yet. (2) Methods: A systematic literature search was conducted in MEDLINE, Embase, CENTRAL, Web of Science, and Scopus. The main outcomes were length of hospital stay (LOHS), time to first flatus and stool, intraoperative fluid and vasopressor requirements, serum lactate levels, and urinary output. Pooled risks ratios (RRs) with 95% confidence intervals (CI) were calculated for dichotomous outcomes and weighted mean difference (WMD) with 95% CI for continuous outcomes. (3) Results: Eleven studies were included in the quantitative, and fifteen in the qualitative synthesis. LOHS (WMD: −1.18 days, 95% CI: −1.84 to −0.53) and time to first stool (WMD: −9.8 h; CI −12.7 to −7.0) were significantly shorter in the GDFT group. GDFT resulted in significantly less intraoperative fluid administration (WMD: −441 mL, 95% CI: −790 to −92) and lower lactate levels at the end of the operation: WMD: −0.25 mmol L−1; 95% CI: −0.36 to −0.14. (4) Conclusions: GDFT resulted in enhanced recovery of the gastrointestinal function and shorter LOHS as compared to N-GDFT.

Assessment of the potential impacts of the Chernobyl nuclear disaster on maternal and fetal health in Hungary

Objective: Radiation exposure is known to be mutagenic and teratogenic. The aim of this study was to analyze the effects of the increased ionizing radiation emitted by the Chernobyl nuclear disaster on maternal and fetal outcomes in Hungary.Methods: A retrospective analysis of abortion, stillbirth, and congenital anomaly data for pregnancies in Hungary between 1 January 1981 and 31 December 1991 was conducted.Results: Trend analysis revealed increasing trends in spontaneous and voluntary abortion rates in Hungary during the study time period, while late pregnancy losses showed a decreasing trend. Overall, there were generally decreasing incidence rates for birth defects throughout the 1980s. Increased voluntary abortions over the study period might reflect, at least in part, maternal anxiety in the post-Chernobyl years. Decreased late pregnancy loss over the same period may be attributable to improvements in prenatal diagnostics. A notable weakness of this study is that missing data could not be complemented due to the decades that have passed since the incident.Conclusions: In conclusion, the present data suggest that the nuclear catastrophe in 1986 did not cause a significant increase in pregnancy loss or congenital malformations in Hungary.

Efficacy of Treatments in Nonarteritic Ischemic Optic Neuropathy: A Systematic Review and Meta-Analysis

Background: Nonarteritic Anterior Ischemic Optic Neuropathy (NAION) is the second most common cause of optic nerve-related permanent visual loss in adults. Aim: We aimed to analyze the efficacy of the noninvasive and minimally invasive therapeutic options of NAION. Methods: We performed a systematic literature search in MEDLINE, EMBASE, and CENTRAL from inception to 10 June 2019 to identify the studies that report on the effect of different therapies on visual acuity (VA) and visual field (VF). Weighted mean difference (WMD) with 95% confidence interval (CI) was calculated for these outcomes. The efficacy of steroids was investigated in quantitative, oxygen, steroid plus erythropoietin (EPO), levodopa/carbidopa, memantine, and heparin-induced extracorporeal LDL/fibrinogen precipitation (HELP) therapies and other therapeutic modalities in qualitative synthesis. Results: Thirty-two studies were found to be eligible. We found that steroid therapy compared to control did not improve VA (p = 0.182, WMD = 0.14, 95% CI: −0.07, 0.35) or VF (p = 0.853, WMD = 0.16, 95% CI: −1.54, 1.86). Qualitative analysis could be performed for oxygen, steroid plus EPO, and HELP as well, however, none of them showed VA and VF benefit. Two individual studies found memantine and levodopa beneficial regarding VA. Conclusion: Our systematic review did not reveal any effective treatment. Further investigations are needed to find therapy for NAION.

current acute pancreatitis prevention by the elimination of alcohol and cigaette smoking (REAPPEAR): protocol of a randomised controlled trial and a cohort study

BACKGROUND/OBJECTIVES

Acute recurrent pancreatitis (ARP) due to alcohol and/or tobacco abuse is a preventable disease which lowers quality of life and can lead to chronic pancreatitis. The REAPPEAR study aims to investigate whether a combined patient education and cessation programme for smoking and alcohol prevents ARP.

METHODS AND ANALYSIS

The REAPPEAR study consists of an international multicentre randomised controlled trial (REAPPEAR-T) testing the efficacy of a cessation programme on alcohol and smoking and a prospective cohort study (REAPPEAR-C) assessing the effects of change in alcohol consumption and smoking (irrespective of intervention). Daily smoker patients hospitalised with alcohol-induced acute pancreatitis (AP) will be enrolled. All patients will receive a standard intervention priorly to encourage alcohol and smoking cessation. Participants will be subjected to laboratory testing, measurement of blood pressure and body mass index and will provide blood, hair and urine samples for later biomarker analysis. Addiction, motivation to change, socioeconomic status and quality of life will be evaluated with questionnaires. In the trial, patients will be randomised either to the cessation programme with 3-monthly visits or to the control group with annual visits. Participants of the cessation programme will receive a brief intervention at every visit with direct feedback on their alcohol consumption based on laboratory results. The primary endpoint will be the composite of 2-year all-cause recurrence rate of AP and/or 2-year all-cause mortality. The cost-effectiveness of the cessation programme will be evaluated.

A systematic review of symptomatic hamartomas of the jejunum and ileum

INTRODUCTION

Gastrointestinal hamartomas are rarely encountered benign growths made of an abnormal mixture of tissues normally found in the body where the growth occurs. Most hamartomas are asymptomatic and diagnosed incidentally. Evidence regarding symptomatic hamartomas of the jejunum and ileum is limited and restricted to anecdotal case reports. We aim to provide a contemporary overview to clarify various aspects linked to symptomatic hamartomas, helping aide management and clinical decision-making.

METHODS

The search terms 'small bowel', 'small intestine', 'jejunum' and 'ileum' were combined with 'hamartoma'. Embase, Medline, PubMed searches and Google Scholar hand-searches were conducted. All English language papers from 1 January 2000 to 1 June 2020 were included.

RESULTS

In total 39 cases were reviewed: 29 adults and 10 paediatric (0-16 years). Presenting symptoms included abdominal pain (87%), vomiting (56%), gastrointestinal bleeding (20.5%) and weight loss (5%); 36 of 39 cases (92%) presented as emergencies. Diagnostic investigations included: abdominal x-ray (49%), endoscopy (38%), computed tomography (56%), magnetic resonance imaging (5%), contrast study (15%) and video capsule endoscopy (5%). Initial management strategy was either open (30) or laparoscopic (7) surgery or endoscopy (2). All cases required surgery for definitive management. Twenty-five cases recorded hamartoma size, and mean maximum diameter was 3.56cm (1.2-8cm) with stricturing in seven cases. Nine of the 39 cases were associated with hamartomatous syndromes. Two mortalities were recorded.

CONCLUSIONS

This is the first published review addressing symptomatic hamartomas of the jejunum and ileum. New data relating to demographic cohort, symptom profile, investigations, management strategies, and morbidity and mortality provide greater insight to those encountering this challenging clinical finding in the future.

The EFFect of dietary fat content on the recurrence of pancreaTitis (EFFORT): Protocol of a multicenter randomized controlled trial

BACKGROUND

Around 20% of patients with acute pancreatitis (AP) will develop acute recurrent pancreatitis (ARP) and 10% will progress to chronic pancreatitis. While interventions to avoid recurrences exist for the two most common causes - abstinence for alcoholic and cholecystectomy for biliary pancreatitis - the are no known preventive measures in idiopathic ARP. Though it is not included in any of the guidelines, a low-fat diet is often recommended. Our aim is to test dietary fat reduction's effect on AP recurrence in a randomized controlled setting, in order to provide high-quality evidence for the validity of such an intervention.

METHODS, DESIGN

Participants with at least 2 episodes of AP in the preceding 2 years of which the last episode was idiopathic will be randomized to one of two diets with different fat contents: a 'reduced fat diet' (15% fat, 65% carbohydrate, 20% protein) and a 'standard healthy diet' (30% fat, 50% carbohydrate, 20% protein; based on WHO recommendations). Participants will be followed-up for 2 years (visits will be scheduled for months 3, 6, 12, 18 and 24) during which they will receive a repeated session of nutritional guidance, complete food frequency questionnaires and data on relapse, mortality, BMI, cardiovascular parameters and serum lipid values will be collected.

DISCUSSION

This study will determine the effect of modifying the dietary fat content on AP recurrence, mortality, serum lipids and weight loss in idiopathic cases.

Influence of COVID-19 pandemic and vaccination on the menstrual cycle: A retrospective study in Hungary

Observations of women and clinicians indicated that the prevalence of menstrual cycle problems has escalated during the COVID-19 pandemic. However, it was not clear whether the observed menstrual cycle changes were related to vaccination, the disease itself or the COVID-19 pandemic-induced psychological alterations. To systematically analyze this question, we conducted a human online survey in women aged between 18 and 65 in Hungary. The menstrual cycle of 1563 individuals were analyzed in our study in relation to the COVID-19 vaccination, the COVID-19 infection, the pandemic itself and the mental health. We found no association between the COVID-19 vaccination, the vaccine types or the COVID-19 infection and the menstrual cycle changes. We also evaluated the menstrual cycle alterations focusing on three parameters of the menstrual cycle including the cycle length, the menses length and the cycle regularity in three pandemic phases: the pre-peak, the peak and the post-peak period in Hungary. Our finding was that the length of the menstrual cycle did not change in any of the periods. However, the menses length increased, while the regularity of the menstrual cycle decreased significantly during the peak of the COVID-19 pandemic when comparing to the pre- and post-peak periods. In addition, we exhibited that the length and the regularity of the menstrual cycle both correlated with the severity of depression during the post-peak period, therefore we concluded that the reported menstrual cycle abnormalities during the peak of COVID-19 in Hungary might be the result of elevated depressive symptoms.

Evaluation of pulse wave velocity for predicting major adverse cardiovascular events in post-infarcted patients; comparison of oscillometric and MRI methods

Increased aortic pulse wave velocity (PWV) has been proved as a strong predictor of major adverse cardiovascular events (MACE) in patients after myocardial infarction (MI). Due to the various technical approaches the level of high PWV values show significant differences. We evaluated the cut-off PWV values for MACE prediction using cardiac magnetic resonance imaging (CMR) and oscillometric methods for validating the prognostic value of high PWV in post-infarcted patients. Phase contrast imaging (PCI) and oscillometric based Arteriograph (AG) were compared in this 6 years follow-up study, including 75 consecutive patients of whom 49 suffered previous ST-elevation myocardial infarction (STEMI). Patients received follow-up for MACE comprising all-cause death, non-fatal MI, ischemic stroke, hospitalization for heart failure and coronary revascularization. An acceptable agreement and significant correlation (rho: 0.332, p < 0.01) was found between AG and CMR derived PWV values. The absolute values, however, were significantly higher for AG (median (IQR): 10.4 (9.2-11.9) vs 6.44 (5.64-7.5) m/s; p < 0.001). Totally 51 MACE events occurred during the 6 years follow-up period in post-infarcted patients. Kaplan-Meier analysis in both methods showed significantly lower event-free survival in case of high PWV (CMR: >6.47 m/s, AG: >9.625 m/s, p < 0.001, respectively). Multivariate Cox regression revealed PWV as a predictor of MACE (PWV CMR hazard ratio (HR): 1.31 (CI: 1.1-1.7), PWV AG HR: 1.24 (CI: 1.0-1.5), p < 0.05, respectively). Increased PWV derived by AG and CMR methods are feasible for MACE prediction in post-infarcted patients. However, adjusted cut-off values of PWV are recommended for different techniques to improve individual risk stratification.

Heat therapy shows benefit in patients with type 2 diabetes mellitus: a systematic review and meta-analysis

AIMS

Type-2 diabetes mellitus (T2DM) is a common health condition which prevalence increases with age. Besides lifestyle modifications, passive heating could be a promising intervention to improve glycemic control. This study aimed to assess the efficacy of passive heat therapy on glycemic and cardiovascular parameters, and body weight among patients with T2DM.

METHODS

A systematic review and meta-analysis were reported according to PRISMA Statement. We conducted a systematic search in three databases (MEDLINE, Embase, CENTRAL) from inception to 19 August 2021. We included interventional studies reporting on T2DM patients treated with heat therapy. The main outcomes were the changes in pre-and post-treatment cardiometabolic parameters (fasting plasma glucose, glycated plasma hemoglobin, and triglyceride). For these continuous variables, weighted mean differences (WMD) with 95% confidence intervals (CIs) were calculated. Study protocol number: CRD42020221500.

RESULTS

Five studies were included in the qualitative and quantitative synthesis, respectively. The results showed a not significant difference in the hemoglobin A1c [WMD -0.549%, 95% CI (-1.262, 0.164), p = 0.131], fasting glucose [WMD -0.290 mmol/l, 95% CI (-0.903, 0.324), p = 0.355]. Triglyceride [WMD 0.035 mmol/l, 95% CI (-0.130, 0.200), p = 0.677] levels were comparable regarding the pre-, and post intervention values.

CONCLUSION

Passive heating can be beneficial for patients with T2DM since the slight improvement in certain cardiometabolic parameters support that. However, further randomized controlled trials with longer intervention and follow-up periods are needed to confirm the beneficial effect of passive heat therapy.

Percutaneous transhepatic drainage is safe and effective in biliary obstruction-A single-center experience of 599 patients

BACKGROUND

Historically, surgical bilioenteric bypass was the only treatment option for extrahepatic bile duct obstruction, but with technological advancements, percutaneous transhepatic drainage (PTD) and endoscopic solutions were introduced as a less invasive alternative. Endoscopic methods may lead to a decreasing indication of PTD in the future, but today it is still the standard treatment method, especially in hilar obstructions.

METHODS

In our retrospective data analysis, we assessed technical success rate, reintervention rate, morbidity, mortality, and the learning curve of patients treated with PTD over 12 years in a tertiary referral center.

RESULTS

599 patients were treated with 615 percutaneous interventions. 94.5% (566/599) technical success rate; 2.7% (16/599) reintervention rate were achieved. 111 minor and 22 major complications occurred including 1 case of death. In perihilar obstruction, cholangitis were significantly more frequent in cases where endoscopic retrograde cholangiopancreatography had also been performed prior to PTD compared to PTD alone, with 39 (18.2%) and 15 (10.5%) occurrences, respectively.

DISCUSSION

The results and especially the excellent success rates demonstrate that PTD is safe and effective, and it is appropriate for first choice in the treatment algorithm of perihilar stenosis. Ultimately, we concluded that PTD should be performed in experienced centers to achieve low mortality, morbidity, and high success rates.
