Review
BACKGROUND
Neonatal jaundice is a prevalent disease that causes many complications, including kernicterus and even death. Previous studies have shown that clofibrate as an aryloxy isobutyric acid derivate can be effectively applied for the treatment of neonatal jaundice. Thus, this review was carried out to investigate the effects and mechanism of action of clofibrate on neonatal jaundice.
METHODS
The keywords such as "Clofibrate" in combination with "Neonatal jaundice" or "Neonatal hyperbilirubinemia" or "Newborn Jaundice" were used to search for relevant publications indexed in the Institute for Scientific Information (ISI), Scopus, PubMed, and Google Scholar databases. Finally, after reviewing the studies, 24 papers were included in this study.
RESULTS
Results showed that the processes of albumin-bound bilirubin transfer to the hepatocytes, hepatic uptake, and storage via ligandin, hepatic conjugation via uridine diphosphate glucuronosyltransferase 1A1 (UGT1A1), conjugation into the bile via MRP2 represent the main action mechanism of clofibrate that turns it into the bilirubin conjugates and expels it from the bile. Besides, clofibrate has been shown to reduce the level of Total Serum Bilirubin (TSB) in infants even at a dosage of 25 mg/kg without leaving side effects.
CONCLUSIONS
The results of this review revealed that clofibrate effectively reduces TSB in short-term usage and can even have a promising effect at the dosage of 25 mg/kg in full-term infants. Most studies have shown this property over a short period in term infants, and there is no evidence about long-term usage in this regard.

Review
This research presents a systematic review focusing on rituximab's therapeutic applications in immunoglobulin G4 (IgG4)-related disease (IgG4-RD), a rare condition characterized by immune-mediated systemic inflammation and tissue fibrosis, as well as the clinical features of IgG4-RD. While the disease commonly affects organs such as the bile ducts, lymph nodes, retroperitoneum, pancreas, and salivary glands, it can potentially involve other organs. This intricacy often leads to diagnostic challenges due to clinical overlaps with cancer, infections, and other autoimmune disorders. The diagnosis of IgG4-RD necessitates a comprehensive approach involving laboratory tests, imaging studies, and clinical assessments. Symptoms can vary, ranging from lymphadenopathy to jaundice, affecting multiple organs. Although elevated blood IgG4 levels and findings of tissue involvement and fibrosis on imaging can be suggestive, they lack the specificity for a definitive diagnosis. Early diagnosis is crucial for initiating corticosteroids and immunosuppressive to prevent further damage from IgG4-RD. This study highlights the therapeutic role of rituximab in managing this condition. Adhering to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) criteria, the research identifies and evaluates relevant literature across various electronic databases, including PubMed, ScienceDirect, and Google Scholar. This review includes 14 selected publications, comprising three systematic reviews, three observational studies, four narrative reviews, and four case reports. The study design ensures a comprehensive evaluation of rituximab's potential efficacy in treating IgG4-RD and its associated clinical characteristics. Based on this study, it can be concluded that IgG4-RD can potentially be treated with rituximab, particularly in cases of relapse and maintaining remission.

Review
ERCP is the current procedure of choice for patients with jaundice caused by biliary obstruction. EUS-guided biliary drainage (EUS-BD) has emerged as an alternative to ERCP in patients requiring biliary drainage. The aim of the study was to conduct a systematic review and meta-analysis to report the overall efficacy and safety of EUS-BD. We conducted a comprehensive search of several databases including PubMed, EMBASE, Web of Science, Google Scholar, and LILACS databases (earliest inception to June 2018) to identify studies that reported EUS-BD in patients. The primary outcome was to look at the technical and clinical success of the procedure. The secondary analysis focused on calculating the pooled rate of re-interventions and all adverse-events, along with the commonly reported adverse-event subtypes. Twenty-three studies reporting on 1437 patients were identified undergoing 1444 procedures. Majority of the patient population were male (53.86%), with an average age of 67.22 years. The pooled technical success rates and clinical success rates were 91.5% (95% confidence interval [CI]: 87.7-94.2, I = 76.5) and 87% (95% CI: 82.3-90.6, I = 72.4), respectively. The total adverse event rates were 17.9% (95% CI: 14.3-22.2, I = 69.1). Subgroup analysis of three major individual adverse events was bile leak: 4.1% (2.7-6.2, I = 46.7), stent migration: 3.9% (2.5-6.2, I = 43.5), and infection: 3.8% (2.8-5.1, I = 0) Substantial heterogeneity was noted in the analysis. EUS-BD has high technical and clinical success rate and hence a very effective procedure. Concerns about publication bias exist. Careful consideration should be given to the adverse events and weighing the risks and benefits of the alternative nonsurgical/surgical approaches.

Journal of Clinical Gastroenterology Jan 2022We aimed to extract the percent of signs and symptoms at the time of diagnosis from published studies and to pool these using meta-analytic techniques.
GOAL
We aimed to extract the percent of signs and symptoms at the time of diagnosis from published studies and to pool these using meta-analytic techniques.
BACKGROUND
Delayed or misdiagnosis of chronic pancreatitis may occur because the signs and symptoms are nonspecific and varied.
STUDY
We performed a systematic review of studies reporting the signs and symptoms of chronic pancreatitis at diagnosis. The percentage of patients with each sign and symptom was extracted and random-effects meta-analyses used to calculate pooled percentages.
RESULTS
In total, 22 observational studies were included. Across 14 studies, 55% of chronic pancreatitis patients were classified as having alcoholic etiology. Abdominal pain was the most common symptom (76%), and weight loss was reported in 22% of patients. Jaundice occurred in 11% of patients and steatorrhoea in 3%. Half of the patients had a history of acute pancreatitis, and 28% had diabetes mellitus at diagnosis. Heterogeneity between the studies was high for all signs and symptoms.
CONCLUSIONS
This research has identified some common features of patients with chronic pancreatitis, but the high heterogeneity makes it difficult to draw solid conclusions. Carefully designed studies to examine the signs and symptoms leading up to a diagnosis of chronic pancreatitis, and common combinations, are required. These would enable the development of a tool to aid in the early identification of chronic pancreatitis in the primary care setting, with potential for improved short-term and long-term outcomes for patients.

Meta-Analysis
OBJECTIVES
This systematic review and meta-analysis study aimed to estimate the overall prevalence of Glucose-6-phosphate dehydrogenase (G6PD) deficiency in neonates with jaundice who were admitted to hospitals in Iran.
MATERIALS AND METHODS
In this systematic review and meta-analysis, we searched PubMed/Medline, Scopus, ISI Web of Sciences, and Iranian Local databases up to December 2019.We calculated Prevalence and 95% Confidence Interval (95% CI) of G6PD deficiency as summary measures. We conducted subgroup analysis based on the sex and quality of studies, while meta-regression were applied for investigating the effect of years of studies and years of publication on the pooled prevalence. We applied sensitivity analysis to investigate the effect of excluding each study on the pooled prevalence estimation.
RESULTS
The total sample size was 9799 people. The pooled prevalence of G6PD deficiency among neonates with jaundice in Iran was 7.0% (95% CI: 5.5-8.5%). The results of subgroup analysis showed that, pooled prevalence of G6PD deficiency among male neonate (12.1%, 95%CI: 7.6-16.7%) was more prevalent that female (3.00%, 95%CI: 1.1-4.9%). Based on the sensitivity analysis, lower and higher pooled prevalence of G6PD deficiency was observed 5.8% (95%CI: 4.7-6.9%) and 7.3% (95%CI: 5.7-8.8%) respectively by excluding each study.
CONCLUSION
The overall prevalence of G6PD deficiency was 7% in Iranian neonates with Jaundice. Prevalence was high in male and early hours of life. We recommend screening test for G6PD deficiency in neonates to prevent its complications.

Review
BACKGROUND
Glucose-6-phosphate dehydrogenase (G6PD) deficiency is a genetic disorder caused by a structural abnormality in the enzyme. G6PD deficiency is most prevalent among African, Asian, and Mediterranean people. This study aimed to investigate how prevalent G6PD deficiency is in African neonates with jaundice.
METHODS
The public sources, such as PubMed, Science Direct, Google Scholar, and Africa Journal Online were searched for articles that reported the prevalence of G6PD deficiency published before March 21st, 2022. The Joanna Briggs Institute's (JBI) critical assessment checklist was used to evaluate the quality of individual studies. STATA-17 was used to do the statistical analysis. The pooled prevalence of G6PD deficiency in neonates with jaundice in Africa was calculated using a forest plot and a random effects model. I statistics and Galbraith plots were used to assess heterogeneity. Publication bias was assessed using a funnel plot and Egger's statistical test.
RESULTS
Ten studies involving 1555 neonates with jaundice were involved in the study. G6PD deficiency was prevalent in 24.60% of African neonates with jaundice (95% CI:12.47-36.74) with considerable heterogeneity (I = 100%). Nigerian neonates with jaundice had the highest G6PD deficiency (49.67%), whereas South Africans had the lowest (3.14%).
CONCLUSION
G6PD deficiency has been implicated in a significant portion of African neonates with jaundice, notwithstanding the need for greater research on predisposing variables from other countries. Therefore, it should be thought of performing screening and diagnostic laboratory tests for G6PD deficiency.

Meta-Analysis
OBJECTIVE
Myelomeningocele (MMC), the most severe form of spina bifida, is characterized by protrusion of the meninges and spinal cord through a defect in the vertebral arches. The management and prevention of MMC-associated hydrocephalus has evolved since its initial introduction with regard to treatment of MMC defect, MMC-associated hydrocephalus treatment modality, and timing of hydrocephalus treatment.
METHODS
The Nationwide Inpatient Sample (NIS) database from the years 1998-2014 was reviewed and neonates with spina bifida and hydrocephalus status were identified. Timing of hydrocephalus treatment, delayed treatment (DT) versus simultaneous MMC repair with hydrocephalus treatment (ST), and treatment modality (ETV vs ventriculoperitoneal shunt [VPS]) were analyzed. Yearly trends were assessed with univariable logarithmic regression. Multivariable logistic regression identified correlates of inpatient shunt failure. A PRISMA systematic literature review was conducted that analyzed data from studies that investigated 1) MMC closure technique and hydrocephalus rate, 2) hydrocephalus treatment modality, and 3) timing of hydrocephalus treatment.
RESULTS
A weighted total of 10,627 inpatient MMC repairs were documented in the NIS, 8233 (77.5%) of which had documented hydrocephalus: 5876 (71.4%) were treated with VPS, 331 (4.0%) were treated with ETV, and 2026 (24.6%) remained untreated on initial inpatient stay. Treatment modality rates were stable over time; however, hydrocephalic patients in later years were less likely to receive hydrocephalus treatment during initial inpatient stay (odds ratio [OR] 0.974, p = 0.0331). The inpatient hydrocephalus treatment failure rate was higher for patients who received ETV treatment (17.5% ETV failure rate vs 7.9% VPS failure rate; p = 0.0028). Delayed hydrocephalus treatment was more prevalent in the later time period (77.9% vs 69.5%, p = 0.0287). Predictors of inpatient shunt failure included length of stay, shunt infection, jaundice, and delayed treatment. A longer time between operations increased the likelihood of inpatient shunt failure (OR 1.10, p < 0.0001). However, a meta-analysis of hydrocephalus timing studies revealed no difference between ST and DT with respect to shunt failure or infection rates.
CONCLUSIONS
From 1998 to 2014, hydrocephalus treatment has become more delayed and the number of hydrocephalic MMC patients not treated on initial inpatient stay has increased. Meta-analysis demonstrated that shunt malfunction and infection rates do not differ between delayed and simultaneous hydrocephalus treatment.

Meta-Analysis Review
BACKGROUND
Hyperbilirubinemia following cardiac surgery is a common phenomenon and is of emerging interest in prognostic factor research. This systematic review and meta-analysis evaluated the association between post-operative hyperbilirubinemia (PH) and mortality and morbidity in cardiac surgery patients.
METHODS
Ovid Medline and Ovid Embase were searched from inception to July 2020 for studies evaluating the prognostic significance of PH following cardiac surgery. Maximally adjusted odds ratios (OR) with associated confidence intervals were obtained from each study and pooled using random effects inverse variance modelling to assess in-hospital mortality. Standardised mean differences were pooled to assess Intensive Care Unit (ICU) and hospital length of stay (LOS). Qualitative analysis was performed to assess ventilation requirements and long-term mortality. Meta-regression was used to assess inter- and intra-study heterogeneity.
RESULTS
3251 studies satisfied the selection criteria, from which 12 studies incorporating 3876 participants were included. PH significantly predicted in-hospital mortality with a pooled OR of 7.29 (95% CI 3.53, 15.09). Multiple pre-defined covariates contributed to the prognostic significance of PH, however only aortic cross-clamp time (p < 0.0001) and number of transfusions (p = 0.0001) were significant effect modifiers. PH significantly predicted both ICU LOS (Mean difference 1.32 [95% CI 0.04-2.6]) and hospital LOS (Mean difference 1.79 [95% CI 0.36-3.21]). Qualitative analysis suggested PH is associated with increased post-operative ventilation requirements and reduced long-term survival rates.
CONCLUSIONS
Hyperbilirubinemia is a cost-effective, widely available prognostic marker of adverse outcomes following cardiac surgery, albeit with residual sources of heterogeneity.

Meta-Analysis
BACKGROUND
Leptospirosis, an important zoonotic bacterial disease, commonly affects resource-poor populations and results in significant morbidity and mortality worldwide. The value of antibiotics in leptospirosis remains unclear, as evidenced by the conflicting opinions published.
METHODS
We conducted a search in the PubMed, Web of Science, and Cochrane Library databases for studies. These studies included clinical trials and retrospective studies that evaluated the efficacy or safety of antibiotics for leptospirosis treatment. The primary outcomes assessed were defervescence time, mortality rate, and hospital stays. Subgroup analyses were performed based on whether there were cases involving children and whether there were cases of severe jaundice. Safety was defined as the prevalence of adverse events associated with the use of antibiotics. p scores were utilized to rank the efficacy of the antibiotics.
RESULTS
There are included 9 randomized controlled trials (RCTs), 1 control trial (CT), and 3 retrospective studies (RS) involving 920 patients and 8 antibiotics. Six antibiotics resulted in significantly shorter defervescence times compared to the control, namely cefotaxime (MD, - 1.88; 95% CI = - 2.60 to - 1.15), azithromycin (MD, - 1.74; 95% CI = - 2.52 to - 0.95), doxycycline (MD, - 1.53; 95% CI = - 2.05 to - 1.00), ceftriaxone (MD, - 1.22; 95% CI = - 1.89 to - 0.55), penicillin (MD, - 1.22; 95% CI = - 1.80 to - 0.64), and penicillin or ampicillin (MD, - 0.08; 95% CI = - 1.01 to - 0.59). The antibiotics were not effective in reducing the mortality and hospital stays. Common adverse reactions to antibiotics included Jarisch-Herxheimer reaction, rash, headache, and digestive reactions (nausea, vomiting, diarrhea, abdominal pain, and others).
CONCLUSIONS
Findings recommend that leptospirosis patients be treated with antibiotics, which significantly reduced the leptospirosis defervescence time. Cephalosporins, doxycycline, and penicillin are suggested, and azithromycin may be a suitable alternative for drug-resistant cases.

Meta-Analysis
BACKGROUND
Jaundice is a life-threatening disorder in the neonates. In the present study, we aimed to assess systematically available evidence on causes and management of jaundice in Iranian newborn patients.
METHODS
We searched the databases of PubMed, Web of Sciences, Scopus and Google Scholar for English articles published since inception until May 2019. A search was also done for Persian articles in Magiran and Scientific Information Database. Studies were evaluated based on predefined criteria by two reviewers. Data analysis was performed by STATA software.
RESULTS
A total of 33 articles were finally included. The overall pooled prevalence of causes of jaundice among Iranian neonates was as follows: ABO blood groups incompatibility, 16.9% [95% confidence interval (CI) 10.9-22.8]; Rh blood group incompatibility, 4% (95% CI 2.5-5.5); ABO and Rh blood groups incompatibility, 3.6% (95% CI 0-7.7); glucose-6-phosphate dehydrogenase (G6PD) deficiency, 6.3% (95% CI 5.1-7.5); infection, 6.6% (95% CI 5.2-8.1); hypothyroidism, 4.2% (95% CI 0.1-8.3); infant of diabetic mother: 2.3% (95% CI 0.1-4.5); unknown, 50.7% (95% CI 33.4-68); cephalohematoma, 0.6% (95% CI 0.3-0.9). Regarding treatment of icterus, seven and eight articles were found on phototherapy and exchange transfusion, respectively. In five studies, all patients underwent phototherapy, but rate of exchange transfusion use was between 6.6% and 50.9%.
CONCLUSIONS
According to the results, unknown factors were the most common causes of icterus in Iranian neonates, followed by ABO blood groups incompatibility, infections and G6PD deficiency. By the way, phototherapy and exchange transfusion were found as therapeutic choices of neonatal jaundice.
