Human cystic echinococcosis (CE) is a parasitic infection caused by the larval stage of the tapeworm Echinococcus granulosus sensu lato, primarily affecting the liver and lungs. Although the heart is affected in only 0.02-2% of all CE cases, a considerable number of cases have been, and continue to be, published. However, due to the rare occurrence of cardiac CE and the resulting lack of clinical trials, knowledge about various aspects of the disease remains limited. To obtain a clearer picture of anatomical, clinical, diagnostic as well as therapeutic aspects of cardiac CE, we systematically reviewed the literature published between 1965 and 2022. The anatomical pattern of the affected cardiac structures follows the extension of the supplying capillary bed. The majority of patients (82.7%) are symptomatic and present with prolonged non-specific symptoms such as dyspnoea, chest pain and palpitations. Acute complications generally derive from cyst rupture, occur in 18.3% of cases and manifest as embolism, pericardial tamponade, or anaphylactic reaction in 83.2%, 17.8% and 10.9% of these cases, respectively. As for CE cysts localized in other organs, the diagnosis of cardiac CE is made by imaging. Serology plays a minor role due to its limited sensitivity. Unlike abdominal CE cysts, cardiac CE cysts are usually resected independent of their stage (active/inactive), because their presence impairs cardiac performance and carries the risk of long-term sequelae. More than 80% of patients are treated with a single surgical intervention. We found a disease-related case fatality rate of 11.1%. Since local recurrence was reported up to 108 months and secondary CE up to 72 months after surgery, patients should be followed up for a minimum of 10 years.

Meta-Analysis
IMPORTANCE
Early-onset colorectal cancer (EOCRC), defined as a diagnosis at younger than age 50 years, is increasing, and so-called red flag signs and symptoms among these individuals are often missed, leading to diagnostic delays. Improved recognition of presenting signs and symptoms associated with EOCRC could facilitate more timely diagnosis and impact clinical outcomes.
OBJECTIVE
To report the frequency of presenting red flag signs and symptoms among individuals with EOCRC, to examine their association with EOCRC risk, and to measure variation in time to diagnosis from sign or symptom presentation.
DATA SOURCES
PubMed/MEDLINE, Embase, CINAHL, and Web of Science were searched from database inception through May 2023.
STUDY SELECTION
Studies that reported on sign and symptom presentation or time from sign and symptom presentation to diagnosis for patients younger than age 50 years diagnosed with nonhereditary CRC were included.
DATA EXTRACTION AND SYNTHESIS
Data extraction and quality assessment were performed independently in duplicate for all included studies using Preferred Reporting Items for Systematic Reviews and Meta-analyses reporting guidelines. Joanna Briggs Institute Critical Appraisal tools were used to measure risk of bias. Data on frequency of signs and symptoms were pooled using a random-effects model.
MAIN OUTCOMES AND MEASURES
Outcomes of interest were pooled proportions of signs and symptoms in patients with EOCRC, estimates for association of signs and symptoms with EOCRC risk, and time from sign or symptom presentation to EOCRC diagnosis.
RESULTS
Of the 12 859 unique articles initially retrieved, 81 studies with 24 908 126 patients younger than 50 years were included. The most common presenting signs and symptoms, reported by 78 included studies, were hematochezia (pooled prevalence, 45% [95% CI, 40%-50%]), abdominal pain (pooled prevalence, 40% [95% CI, 35%-45%]), and altered bowel habits (pooled prevalence, 27% [95% CI, 22%-33%]). Hematochezia (estimate range, 5.2-54.0), abdominal pain (estimate range, 1.3-6.0), and anemia (estimate range, 2.1-10.8) were associated with higher EOCRC likelihood. Time from signs and symptoms presentation to EOCRC diagnosis was a mean (range) of 6.4 (1.8-13.7) months (23 studies) and a median (range) of 4 (2.0-8.7) months (16 studies).
CONCLUSIONS AND RELEVANCE
In this systematic review and meta-analysis of patients with EOCRC, nearly half of individuals presented with hematochezia and abdominal pain and one-quarter with altered bowel habits. Hematochezia was associated with at least 5-fold increased EOCRC risk. Delays in diagnosis of 4 to 6 months were common. These findings highlight the need to identify concerning EOCRC signs and symptoms and complete timely diagnostic workup, particularly for individuals without an alternative diagnosis or sign or symptom resolution.

BACKGROUND
Pembrolizumab is associated with the development of gastritis, but its clinical features have not been characterized. To explore the clinical features of pembrolizumab induced gastritis and provide reference for the prevention and treatment of gastritis.
METHODS
Case reports and case series related to pembrolizumab induced gastritis were retrospectively analyzed by searching the database from inception to September 30, 2023.
RESULTS
Thirty-nine patients with gastritis entered the study with a median age of 63 years (range 34, 81). The median time to gastritis was 11.1 months (range 0.3, 60) and 7 cycles (range 1, 27) after administration. Epigastric pain (24 cases, 61.5%), nausea (17 cases, 43.6%), and vomiting (16 cases, 41.0%) were the most frequently complained symptoms. Esophagogastroduodenoscopy mainly showed erythematous (16 cases, 41.0%), hemorrhage (14 cases, 35.9%) and erosions (11 cases, 28.2%). Gastric mucosal biopsy shows chronic active gastritis with lymphocytic infiltration. These patients' symptoms and gastric mucosa improved or recovered after receiving systemic steroid and proton pump inhibitor therapy regardless of whether pembrolizumab was discontinued. These patients' symptoms and gastric mucosa improved or recovered after treatment with systemic steroids, proton pump inhibitors, and biological agents.
CONCLUSIONS
Gastritis is an extremely rare adverse effect of pembrolizumab. When patients receiving pembrolizumab complain of abdominal symptoms, endoscopy, tissue biopsy, and immunohistochemical staining should be actively performed for early identification and diagnosis of gastritis.

BACKGROUND
Acute appendicitis remains as a differential diagnosis in older patients with abdominal pain. The Alvarado scale may assist to guide the diagnosis and treatment of this entity. The operative characteristics of the scale are little known in this population.
METHOD
We conducted a systematic review of original studies published between 1986 and 2022 evaluating the diagnostic performance of the Alvarado scale in older adults with suspected acute appendicitis. The review was conducted according to the PRISMA statement. The evaluation of the methodological quality of the studies was performed according to the ROBINS-I criteria.
RESULTS
Four original studies of retrospective design including 480 patients were identified. The heterogeneity and poor methodological quality limited an aggregate statistical analysis (meta-analysis). The value of the ROC curve of the scale varies between 0.799 and 0.969. From the available studies, the value of the ROC curve is lower in comparison to the RIPASA scale and comparable to the Lintula scale.
CONCLUSIONS
The evidence on the diagnostic performance of the Alvarado scale in older adults is limited. The poor methodological quality of the available studies calls for a prudent use of this tool in this population. Our findings offer opportunities for future research.

BACKGROUND
Endoscopic ultrasound-guided portal pressure gradient measurement (EUS-PPG) is a new modality where the portal pressure is measured by directly introducing a needle into the hepatic vein and portal vein. This is the first systematic review and meta-analysis to evaluate the efficacy and safety of EUS-PPG.
METHODS
A comprehensive literature search was performed to identify pertinent studies. The primary outcomes assessed were the technical and clinical success of EUS-PPG. Technical success was defined as successful introduction of the needle into the desired vessel, while clinical success was defined as the correlation of the stage of fibrosis on the liver biopsy to EUS-PPG, or concordance of HVPG and EUS-PPG. The secondary outcomes were pooled rates for total and individual adverse events related to EUS-PPG. Pooled estimates were calculated using random-effects models with a 95% confidence interval (CI).
RESULTS
Eight cohort studies with a total of 178 patients were included in our analysis. The calculated pooled rates of technical success and clinical success were 94.6% (95%CI 88.5-97.6%; P=<0.001; =0) and 85.4% (95%CI 51.5-97.0%; P=0.042; =70), respectively. The rate of total adverse events was 10.9% (95%CI 6.5-17.7%; P=<0.001; =4), and 93.7% of them were mild, as defined by the American Society for Gastrointestinal Endoscopy. Abdominal pain (11%) was the most common adverse event, followed by bleeding (3.6%). There were no cases of perforation or death reported in our study.
CONCLUSIONS
EUS-PPG is a safe and effective modality for diagnosing portal hypertension. Further randomized controlled trials are needed to validate our findings.

BACKGROUND & AIMS
Some brain-gut behavioral treatments (BGBTs) are beneficial for global symptoms in irritable bowel syndrome (IBS). United States management guidelines suggest their use in patients with persistent abdominal pain, but their specific effect on this symptom has not been assessed systematically.
METHODS
We searched the literature through December 16, 2023, for randomized controlled trials (RCTs) assessing efficacy of BGBTs for adults with IBS, compared with each other or a control intervention. Trials provided an assessment of abdominal pain resolution or improvement at treatment completion. We extracted data as intention-to-treat analyses, assuming dropouts to be treatment failures and reporting pooled relative risks (RRs) of abdominal pain not improving with 95% confidence intervals (CIs), ranking therapies according to the P score.
RESULTS
We identified 42 eligible randomized controlled trials comprising 5220 participants. After treatment completion, the BGBTs with the largest numbers of trials and patients recruited demonstrating efficacy for abdominal pain, specifically, included self-guided/minimal contact cognitive behavioral therapy (CBT) (RR, 0.71; 95% CI, 0.54-0.95; P score, 0.58), face-to-face multicomponent behavioral therapy (RR, 0.72; 95% CI, 0.54-0.97; P score, 0.56), and face-to-face gut-directed hypnotherapy (RR, 0.77; 95% CI, 0.61-0.96; P score, 0.49). Among trials recruiting only patients with refractory global IBS symptoms, group CBT was more efficacious than routine care for abdominal pain, but no other significant differences were detected. No trials were low risk of bias across all domains, and there was evidence of funnel plot asymmetry.
CONCLUSIONS
Several BGBTs, including self-guided/minimal contact CBT, face-to-face multicomponent behavioral therapy, and face-to-face gut-directed hypnotherapy may be efficacious for abdominal pain in IBS, although none was superior to another.

Review
BACKGROUND
Various exercise programs are used to treat lateral abdominal muscle (LAM) impairments in people with low back pain. Factors comprising these programs include exercise type, session time, frequency, and program duration. However, specific clinical guidance about optimal exercise prescription is lacking.
OBJECTIVES
To perform a dose-response analysis on exercise prescription variables for LAM thickness and activation as measured by ultrasound imaging.
DESIGN
Systematic review METHOD: Databases were searched from their inception for studies examining the association between exercise interventions and LAM thickness/activation measured by ultrasound imaging in healthy individuals. Risk of bias was assessed using the Joanna Brigg's Institute critical appraisal tools. For each muscle, subgroup analyses were performed to determine the dose response of exercise prescription variables for LAM thickness and activation. Where there was insufficient data for subgroup analyses, data was narratively synthesised.
RESULTS
Fourteen studies comprising 395 participants were included. Statistical and narrative synthesis revealed specific local abdominal exercises, programs from four weeks duration, three sessions per week and sessions of ≥30 min were associated with greatest improvements to LAM thickness. Only the variables exercise type, program duration and session frequency showed a significant between groups difference for the subgroup analysis. The main limitation was inability to perform subgroup analyses for all variables across all muscles measured at rest and during contraction, due to non-reporting of data.
CONCLUSION
This review provides preliminary guidance to practitioners on how the LAM respond to different exercise dosages. Future research should trial these findings.

BACKGROUND
Abdominal compartment syndrome (ACS) is typically attributed to critically unwell patients with trauma, burns, post surgery, and massive ascites. A rare but fatal cause of ACS is bulimia nervosa (BN), which is an eating disorder characterized by bingeing, followed by methods to avoid weight gain, including purging.
CASE REPORT
We present a case of a 20-year-old woman who presented with abdominal pain and distension after consuming a large quantity of food the previous night and was unable to purge. She was initially managed conservatively and discharged home, but returned subsequently on the same day with clinical features of ACS secondary to acute gastric distension. Decompression resulted in life-threatening reperfusion injury with critical electrolyte abnormalities and fatal cardiac arrest in the operating theatre. WHY SHOULD AN EMERGENCY PHYSICIAN BE AWARE OF THIS?: A systematic review of the literature found only 11 case reports of ACS secondary to BN, of which only 6 patients survived due to early diagnosis and decompression. Inability to purge and lower limb ischemia appeared to be associated with increased mortality. As BN is a common emergency presentation, the case and systematic review highlights the need to consider ACS as a potentially life-threatening complication of binge eating, particularly when there is unsuccessful purging.

Meta-Analysis Comparative Study
BACKGROUND
The efficacy of fascia iliaca block (FIB) versus quadratus lumborum block (QLB) remains controversial for pain management of hip arthroplasty. We conduct a systematic review and meta-analysis to explore the influence of FIB versus QLB on the postoperative pain intensity of hip arthroplasty.
METHODS
We have searched PubMed, EMbase, Web of Science, EBSCO, and Cochrane Library databases through July 2023 for randomized controlled trials assessing the effect of FIB versus QLB on pain control of hip arthroplasty. This meta-analysis is performed using the random-effect model or fixed-effect model based on the heterogeneity.
RESULTS
Four randomized controlled trials and 234 patients were included in the meta-analysis. Overall, compared with QLB for hip arthroscopy, FIB was associated with substantially lower pain scores at 2 hours (mean difference [MD] = -0.49; 95% CI = -0.63 to -0.35; P < .00001) and pain scores at 12 hours (MD = -0.81; 95% CI = -1.36 to -0.26; P = .004), but showed no impact on pain scores at 24 hours (MD = -0.21; 95% CI = -0.57 to 0.15; P = .25), time to first rescue analgesia (standard mean difference = 0.70; 95% CI = -0.59 to 1.99; P = .29), analgesic consumption (MD = -4.80; 95% CI = -16.57 to 6.97; P = .42), or nausea and vomiting (odd ratio = 0.66; 95% CI = 0.32-1.35; P = .25).
CONCLUSIONS
FIB may be better than QLB for pain control after hip arthroplasty, as evidenced by the lower pain scores at 2 and 24 hours.

Review
Epiploic appendagitis (EA) is an essential cause of abdominal pain that can be confused with more typical causes such as acute diverticulitis and appendicitis. Epiploic appendagitis accounts for 1% of all cases of abdominal pain in adults. The scarcity of information has limited its recognition as an essential nonsurgical cause of acute abdominal pain. We performed a systematic review of all EA cases published. We searched Scopus, Medline, Web of Science, and Google Scholar to retrieve all available studies from January 2000 to November 2023. 196 case reports and case series were analyzed, with 371 patients with EA included. The mean age at the time of diagnosis was 39 years. Most patients were male (59%). The primary presenting symptoms were pain (100%), tenderness (59.5%), and rebound tenderness (27.4%). The left abdomen was the most common localization of pain (53%). The most frequently identified differential diagnoses were acute appendicitis (26.4%) and acute diverticulitis (16.1%). Most patients (53%) were treated conservatively, and 98 (26.4%) underwent surgical treatment. A significant difference in the choice of treatment was found for signs and symptoms such as rebound tenderness, nausea, anorexia, and diarrhea. Acute EA is an essential clinical condition of rare occurrence that might present a diagnostic challenge, as it can masquerade as another acute abdominal pain etiology. The optimal management of EA is conservative, so a higher recognition by surgeons and emergency physicians is essential to avoid unnecessary surgical interventions and their associated consequences.
