Meta-Analysis Review
INTRODUCTION
Obesity is a risk factor for chronic diseases and premature mortality, but the extent of these associations among the elderly is under debate. The aim of this systematic literature review (SR) is to collate and critically assess the available information of the impact of obesity on mortality in the elderly.
METHODS
In PubMed, there are three-hundred twelve papers on the relationship between obesity and mortality among older adults. These papers were analysed on the basis of their abstracts, and sixteen studies were considered suitable for the purpose of the study. It was possible to perform a pooled estimate for aggregated data in three different studies.
CONCLUSION
The results of this SR document that an increased mortality in obese older adults. The limitation of BMI to index obesity and the noted protective action of a moderate increase in BMI on mortality are highlighted. Waist circumference is an indicator of central adiposity and potentially as good a risk factor for mortality as BMI in obese elderly adults.

The Impact of Ready-to-Eat Cereal Intake on Body Weight and Body Composition in Children and Adolescents: A Systematic Review of Observational Studies and Controlled Trials.
Results from observational studies suggest that children and adolescents consuming ready-to-eat cereals (RTECs) have a healthier BMI and lower odds of overweight and obesity than consumers of other breakfasts or breakfast skippers. However, randomized controlled trials in children and adolescents are few and have been inconsistent in demonstrating a causal relationship between RTEC intake and body weight or body composition. The objective of this study was to evaluate the effect of RTEC intake on body weight and body composition outcomes in children and adolescents. Prospective cohort, cross-sectional and controlled trials in children or adolescents were included. Retrospective studies and studies in subjects with disease, other than obesity, type-2 diabetes (T2D), metabolic syndrome, or prediabetes, were excluded. A search in PubMed and CENTRAL databases yielded 25 relevant studies, which were qualitatively analyzed. Fourteen of the 20 observational studies demonstrated that children and adolescents consuming RTEC have a lower BMI, lower prevalence and odds of overweight/obesity and more favorable indicators of abdominal obesity than nonconsumers or less frequent consumers. Controlled trials were few and only one reported a loss of 0.9 kg in overweight/obese children with RTEC consumption when accompanied by nutrition education. The risk of bias was low for most studies, but six had some concerns or high risk. The results were similar with presweetened and nonpresweetened RTEC. No studies reported a positive association of RTEC intake with body weight or body composition. Although controlled trials do not show a direct effect of RTEC consumption on body weight or body composition, the preponderance of observational data supports the inclusion of RTEC as part of a healthy dietary pattern for children and adolescents. Evidence also suggests similar benefits on body weight and body composition regardless of the sugar content. Additional trials are needed to determine the causality between RTEC intake and body weight and body composition outcomes. PROSPERO REGISTRATION: CRD42022311805.

Review
A mesenteric cyst is defined as a cyst that is located in the mesentery of the gastrointestinal tract and may extend from the base of the mesentery into the retroperitoneum. A case report of a patient with mesenteric cyst is presented. In addition, a systematic review was performed of English language literature on chylous mesenteric cysts in adult humans. Of the 18 articles included in the review, there were 19 cases of chylous mesenteric cysts reported. Male to female ratio was 1.4:1 with a median age of 46 years. A preoperative diagnosis of mesenteric cyst was made in four patients based on computed tomography. All patients underwent surgery and there were no reports of recurrence on follow up. Chylous mesenteric cyst is a rare entity that needs to be recognized whenever a preliminary diagnosis of intra-abdominal cystic mass is made.

Review
Which preoperative assessment modalities best identify patients who are suitable for enhanced recovery after liver transplantation? A systematic review of the literature and expert panel recommendations.
BACKGROUND
To implement Enhanced Recovery After Surgery (ERAS) protocols for liver transplant (LT) candidates, it is essential to identify tools that can help risk stratify patients by their risk of early adverse post-LT outcomes.
OBJECTIVE
We aimed to identify pre-LT tools that assess functional capacity, frailty, and muscle mass that can best risk stratify patients by their risk of adverse post-LT outcomes.
METHODS
We first conducted a systematic review following PRISMA guidelines, expert panel review and recommendations using the GRADE approach (PROSPERO ID CRD42021237434). After confirming there are no studies evaluating assessment modalities for ERAS protocols for LT recipients specifically, the approach of the review focused on pre-LT modalities that identify LT recipients at higher risk of worse early post-LT outcomes (≤90 days), considering that this is particularly pertinent when evaluating candidates for ERAS.
RESULTS
Twenty-two studies were included in the review, encompassing three different types of pre-LT modalities: evaluation of physical function (including frailty and general physical scores like the Karnofsky Performance Status (KPS), assessment of cardiopulmonary capacity, and estimation of muscle mass and composition. The majority of studies evaluated frailty assessment and muscle mass. Most studies, except for liver frailty index (LFI), were retrospective and single-center. All assessment modalities could identify, in different grade, LT recipients with higher risk of early post-LT mortality, length of stay or postoperative complications.
CONCLUSIONS
We identified four pre-LT assessment tools that could be used to identify patients who are suitable for ERAS protocols: (1) KPS (quality of evidence moderate, grade of recommendation strong); (2) LFI (quality of evidence moderate, grade of recommendation strong); (3) abdominal muscle mass by CT (quality of evidence moderate, grade of recommendation strong); and (4) cardiopulmonary exercise testing (CPET) (quality of evidence moderate, grade of recommendation weak). We recommend that selection of the appropriate tool depends on the specific clinical setting and available resources to administer the tool, and that use of a tool be incorporated into the routine preoperative assessment when considering implementation of ERAS protocols for LT.

BACKGROUND
The diagnosis of B-cell lymphoma, one of the commonest cancers seen in childhood and adolescence, is challenging. There is a crucial need to identify and delineate the prevalence of associated symptoms in order to improve early diagnosis.
AIMS
To identify clinical presentations associated with childhood and adolescent B-cell lymphomas and estimate symptom prevalence.
METHODS
A systematic review of observational studies and meta-analysis of proportions was carried out. Medline and EMBASE were systematically searched, with no language restrictions, from inception to 1st August 2022. Observational studies with at least 10 participants, exploring clinical presentations of any childhood and adolescent lymphoma, were selected. Proportions from each study were inputted to determine the weighted average (pooled) proportion, through random-effects meta-analysis.
RESULTS
Studies reported on symptoms, signs and presentation sites at diagnosis of 12,207 children and adolescents up to the age of 20. Hodgkin's lymphoma most frequently presented with adenopathy in the head-and-neck region (79% [95% CI 58%-91%]), whilst non-Hodgkin's lymphoma presented abdominally (55% [95% CI 43%-68%]). Symptoms associated with lymphoma included cervical lymphadenopathy (48% [95% CI 20%-77%]), peripheral lymphadenopathy (51% [95% CI 37%-66%]), B-symptoms (40% [95% CI 34%-44%]), fever (43% [95% CI 34%-54%]), abdominal mass (46% [95% CI 29%-64%]), weight loss (53% [95% CI 39%-66%]), head-and-neck mass (21% [95% CI 6%-47%]), organomegaly (29% [95% CI 23%-37%]), night sweats (19% [95% CI 10%-32%]), abdominal pain (28% [95% CI 15%-47%]), bone pain (17% [95% CI 10%-28%]) and abnormal neurology (11% [95% CI 3%-28%]).
CONCLUSION
This systematic review and meta-analysis of proportions provides insight into the heterogeneous clinical presentations of B-cell lymphoma in childhood and adolescence and provides estimates of symptom prevalence. This information is likely to increase public and clinical awareness of lymphoma presentations and aid earlier diagnosis. This review further highlights the lack of studies exploring childhood and adolescent lymphoma presentations in primary care, where patients are likely to present at the earliest stages of their disease.

Meta-Analysis
BACKGROUND
Higher body mass index and waist circumference have been associated with increased risk of pancreatitis in several prospective studies; however, the results have not been entirely consistent.
AIMS
We conducted a systematic review and dose-response meta-analysis of prospective studies on adiposity and risk of pancreatitis to clarify this association.
METHODS
PubMed and Embase databases were searched for studies on adiposity and pancreatitis up to January 27, 2020. Prospective studies reporting adjusted relative risk (RR) estimates and 95% confidence intervals (CIs) for the association between adiposity and risk of pancreatitis were included, and summary RRs (95% CIs) were calculated using a random effects model.
RESULTS
Ten prospective studies with 5129 cases and 1,693,657 participants were included. The summary RR (95% CI) of acute pancreatitis was 1.18 (95% CI: 1.03-1.35, I = 91%, n = 10 studies) per 5 kg/m increase in BMI and 1.36 (95% CI: 1.29-1.43, I = 0%, n = 3) per 10 cm increase in waist circumference. There was evidence of a nonlinear association between BMI and acute pancreatitis, p < 0.0001, with a steeper association at higher levels of BMI, but not for waist circumference, p = 0.19. Comparing a BMI of 35 with a BMI of 22, there was a 58% increase in the RR and there was a fourfold increase in the RR comparing a waist circumference of 110 cm with 69 cm. There was no evidence of publication bias.
CONCLUSIONS
This meta-analysis suggests that both increasing BMI and waist circumference are associated with a dose-response-related increase in the risk of acute pancreatitis.

Meta-Analysis Review
BACKGROUND
Single-incision laparoscopic surgery has gained widespread attention because of its potential benefits such as less skin incision and faster recovery. Up to now, only one meta-analysis (performed in 2013; including 9 studies, a total of 585 cases) compared single-incision laparoscopic right colectomy (SILRC) with conventional laparoscopic right colectomy (CLRC). An updated meta-analysis was undertaken to explore more convinced comparative findings between SILRC and CLRC.
MATERIALS AND METHODS
The search for studies that compared SILRC with CLRC was done on PubMed, Embase, Web of Science, and the Cochrane Library. A total of 17 studies (including 1778 cases) were identified, the data of appointed outcomes were extracted and analyzed.
RESULTS
Patient demographics (age, gender, body mass index and previous abdominal operation) did not differ significantly. No significant differences were found between SILRC and CLRC in operative time, conversion, reoperation, perioperative complications, postoperative mortality, and 30-days readmission. Pathological outcomes, including lymph nodes harvested, proximal resection margin, and distal resection margin, were similar. SILRC showed less estimated blood loss (weighted mean difference [WMD]: -15.67 ml; 95% confidence interval [CI], -24.36 to -6.98; p = 0.0004), less skin incisions (WMD: -1.56 cm; 95%CI, -2.63 to -0.49; p = 0.004) and shorter hospital stay (WMD: -0.73d; 95%CI, -1.04 to -0.41; p < 0.00001), without publication bias.
CONCLUSION
SILRC may provide a safe and feasible alternative to CLRC with similar short-term outcomes and aesthetic advantage of less skin incision. Well-designed randomized controlled trials, involving large cases and carrying long-term outcomes, are needed.

OBJECTIVE
Spontaneous iliac vein rupture (SIVR) is a rare but life-threatening condition with limited understanding regarding its clinical presentation, pathogenesis, diagnosis, management, and risk factors for mortality. This study aims to address this gap by providing comprehensive insights into SIVR through personal case reports and a systematic review of previous cases.
METHODS
We detail a case of right SIVR caused by inappropriate positioning of the stent in the inferior vena cava and systematically reviewed previous cases. Logistic regression analysis was used to identify risk factors for mortality.
RESULTS
Our SIVR case was successfully managed with percutaneous mechanical thrombectomy and covered stent placement. In the systematic review, 68 patients were included in the analysis with an average age of 62.01 ± 13.25 years; 86.76% were female, 91.17% had left iliac vein rupture, 55.88% presented hemodynamic instability, 76.47% had lower abdomen or iliac fossa pain, 67.64% had deep venous thrombosis (DVT), and 32.35% had May‒Thurner syndrome (MTS). The mortality rates of conservative treatment and open surgery were 2.94% and 17.65%, respectively. All 12 patients receiving endovascular treatment survived. The factors associated with a worse outcome were younger age (52.86 ± 12.96 years, OR: 1.085, 95% CI: 1.002-1.174) and SIVR patients without DVT (OR:10.111, 95% CI: 1.637-62.443).
CONCLUSION
This first systematic review on SIVR shows that SIVR should be highly suspected in elderly females who develop lower extremity DVT and concurrent lower abdominal pain, particularly those with a retroperitoneal mass and unstable hemodynamics. Thrombosis secondary to MTS may be the main cause of SIVR. Angiography and endovascular therapy should be prioritized for DVT patients with unexplained retroperitoneal hematoma. This study classifies SIVR into two types: iliac vein rupture alone and iliac vein rupture with DVT. These findings provide critical insights for clinicians to accurately diagnose and manage SIVR, thereby improving patient outcomes.

Review
Results from observational studies indicate that consumption of ready-to-eat cereal (RTEC) is associated with higher diet quality and lower incidence of overweight and obesity in adults compared with other breakfasts or skipping breakfast. However, randomized controlled trials (RCTs) have had inconsistent results regarding effects of RTEC consumption on body weight and composition. This systematic review aimed to evaluate the effect of RTEC intake on body weight outcomes in observational studies and RCTs in adults. A search of PubMed and Cochrane Central Register of Controlled Trials (CENTRAL) databases yielded 28 relevant studies, including 14 observational studies and 14 RCTs. Results from observational studies demonstrate that frequent RTEC consumers (usually ≥4 servings/wk) have lower BMI, lower prevalence of overweight/obesity, less weight gain over time, and less anthropometric evidence of abdominal adiposity compared with nonconsumers, or less frequent consumers. RCT results suggest that RTEC may be used as a meal or snack replacement as part of a hypocaloric diet, but this approach is not superior to other options for those attempting to achieve an energy deficit. In addition, RTEC consumption was not associated with significantly less loss of body weight, or with weight gain, in any of the RCTs. RTEC intake is associated with favorable body weight outcomes in adults in observational studies. RTEC does not hinder weight loss when used as a meal or snack replacement within a hypocaloric diet. Additional long-term RCTs (≥6 mo) in both hypocaloric and ad libitum conditions are recommended to evaluate further the potential effects of RTEC consumption on body weight outcomes.

Meta-Analysis Review
BACKGROUND
This systematic review aims to evaluate the effects of exercise combined with diet (ECWD), exercise alone, diet alone, and no intervention on body composition and serum biochemical markers in adolescents with obesity to provide reference for solving the metabolic disorders of adolescents caused by obesity.
CONTENTS
Studies published before January 5, 2021 were retrieved from PubMed, Web of Science, Ovid, Cochrane Library, China National Knowledge Infrastructure (CNKI), Wanfang data, VIP database, and SinoMed. Randomized controlled trials with an age between 10 and 20 years, body mass index (BMI) ≥28 kg/m or ≥95th percentiles, no history of endocrine and metabolic diseases, heart disease, hematologic disease, and so on before the trial were included.
SUMMARY
Fifteen of the 50,155 studies met the criteria. Meta-analysis showed that ECWD was more effective in reducing BMI (kg/m) (-2.45 kg/m, 95% CI: -3.06; -1.85) and fat thickness of back (-13.77 mm, 95% CI: -15.92; -11.62), abdomen (-11.56 mm, 95% CI: -14.04; -9.09), and upper arm (-14.81 mm, 95% CI: -16.74; -12.89) than other interventions; in reducing body fat (-7.03 kg, 95% CI: -9.77; -4.29) and thigh circumference (-4.05 cm, 95% CI: -5.58; -2.52), ECWD and diet alone were more effective than exercise alone; ECWD and exercise alone were more effective in reducing waist circumference (-6.05 cm, 95% CI: -8.37; -3.72), waist-to-hip ratio (WHR; -0.06, 95% CI: -0.11; -0.01), upper arm circumference (-2.57 cm, 95% CI: -3.70; -1.45), triglycerides (TG; -0.30 mmol/L, 95% CI: -0.45; -0.14), total cholesterol (TC; -0.30 mmol/L, 95% CI: -0.59; -0.01), and low density lipoprotein (LDL; -0.22 mmol/L, 95% CI: -0.40; -0.04) than diet alone. ECWD also had effects on tumor necrosis factor-α (TNF-α), interleukin-6, leptin, and so on.
OUTLOOK
ECWD is more effective than exercise alone, diet alone, or no intervention in solving the problems of body shape and metabolic disorder of adolescents with obesity.
