Review
As the global incidence of idiopathic pulmonary fibrosis (IPF) is on the rise, there is a need for better diagnostic criteria, better treatment options, early and appropriate diagnosis, adequate care, and a multidisciplinary approach to the management of patients. This systematic review explores the role of proton pump inhibitors (PPIs) in IPF and answers the question, "Does proton pump inhibitor improve only the prognosis of gastroesophageal associated idiopathic pulmonary fibrosis or for other types of idiopathic pulmonary fibrosis too?" We used PubMed (PMC) and Google Scholar for data collection for this systematic review and followed the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines for conducting this review. After in-depth literature screening and quality appraisal, 12 articles were selected for this systematic review. On the one hand, the efficacy of PPI therapy is supported by research such as the CAPACITY and ASCEND trials, a pilot randomized control trial (RCT) investigating the role of omeprazole in IPF and a bidirectional two-sample Mendelian randomization (MR) study, respectively. On the other hand, a systematic review and meta-analysis on antacid and antireflux surgery in IPF negate these results and show no statistical significance. Questions regarding the efficacy of PPI therapy must be dealt with in an adequately powered multicenter and double-blinded randomized control trial. The anti-inflammatory properties of antacids can serve as the cornerstone for future trials. In the following systematic review, antacid, antireflux therapy, omeprazole, and proton pump therapy are synonymous with stomach acid suppression therapy.

Meta-Analysis
BACKGROUND
Around 5-20% of patients who undergo surgery for advanced gastric cancer (AGC), which invades into the muscularis propria or beyond, have peritoneal carcinomatosis. The peritoneal recurrence rate is 10-54%, which is associated with a poor prognosis. The role of hyperthermic intraperitoneal chemotherapy (HIPEC) in AGC with and without peritoneal carcinomatosis is not clearly defined.
METHODS
The authors conducted a meta-analysis, in accordance with the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines, of the clinical trials and high-quality nonrandomized studies evaluating the role of HIPEC in AGC over the last 10 years. The studies were searched in PubMed, EMBASE, MEDLINE, and Cochrane databases between January 2011 to December 2021. Clinical data including overall survival, recurrence free survival, overall recurrence rate, peritoneal recurrence rate, and complications analyzed using RevMan 5.4.
RESULTS
Six randomized controlled trials and 10 nonrandomized studies, comprising a total of 1700 patients were included. HIPEC was associated with significantly improved OS at 3 [odd ratio (OR) 1.89, 95% CI: 1.17-3.05] and 5 years (OR 1.87, 95% CI: 1.29-2.71). HIPEC was associated with reduced overall recurrence (OR 0.49, 95% CI: 0.31-0.80) and peritoneal recurrence (OR 0.22, 95% CI: 0.11-0.47). HIPEC was not associated with increased complications. The occurrence of postoperative renal dysfunction was significantly higher in the HIPEC group (OR 3.94, 95% CI: 1.85-8.38).
CONCLUSION
The role of HIPEC in AGC has evolved over the past decade. HIPEC may improve survival rates and reduce recurrence rates in patients with AGC, without significant increase in complications and with a favorable impact on 3 and 5-year survival.

Meta-Analysis Review
BACKGROUND
Postoperative pancreatic fistula (POPF) is a common and serious consequence of gastrectomy. The prevalence of POPF among patients with gastric cancer varies greatly, and the risk factors and outcomes of POPF are also controversial. The meta-analysis aims to comprehensively assess the risk factors for POPF in gastric cancer patients.
METHODS
PubMed, Web of Science, the Cochrane Library, Embase, and Chinese databases (SinoMed, CNKI, WanFang, and VIP Databases) were searched to identify relevant studies (from inception to May 2023). Two researchers evaluated the literature quality and extracted data individually. The Review Manager 5.4 program was used to analyze all of the data.
RESULTS
In our meta-analysis, 22 studies totaling 11,647 patients were analyzed. Male sex (OR = 3.06), older age (OR = 3.22), body mass index (BMI) ≥ 25 kg/m (OR = 2.58), visceral fat area (VFA) ≥ 100 cm (OR = 3.65), pTNM Ⅲ-Ⅳ (OR = 2.47), the number of lymphlode dissections (OR = 1.04), neoadjuvant chemotherapy (NAC) (OR = 2.91), the application of LigaSure (OR = 3.30), open surgery (OR = 3.23), intraoperative combined organ resection (OR = 4.11), drainage amylase concentration on the first postoperative day (OR = 5.73) and C-reactive protein on the 3rd postoperative day ≥20 mg/dL (OR = 7.29) were the risk factors for POPF in gastric cancer patients. On the other hand, the operation time (OR = 1.34) was not a risk factor for POPF.
CONCLUSION
The frequency of POPF in people undergoing gastrectomy was determined by a variety of risk factors. Medical professionals should identify risk factors early and impose interventions to prevent them to lower the incidence of POPF in gastric cancer patients.

Review
BACKGROUND
Oesophago-gastric cancer is an aggressive disease with a high rate of recurrence and mortality across the disease trajectory. Reduced psychosocial functioning has been evidenced amongst those with advanced disease, however little is known about the contributing factors. Determining these factors is an important clinical consideration to inform assessment and intervention. This review aimed to synthesise the available evidence on the psychosocial functioning of individuals with advanced oesophago-gastric cancer and their carers.
METHODS
A JBI mixed-methods systematic review. Four bibliographic databases, MEDLINE, Embase, PsycINFO, and CINAHL, were searched. Quantitative and qualitative studies were screened for inclusion and critically appraised for methodological quality. Both types of data were extracted using JBI tools for mixed-methods systematic reviews. A convergent segregated approach to synthesis and integration was used. The findings of the synthesis have been configured according to JBI methodology.
RESULTS
A total of 12 studies were included in this review, including 6 quantitative studies and 6 qualitative studies. The quantitative results provide preliminary indication of several physical, biological, psychological and macro-level contextual factors associated with psychosocial functioning in this clinical population. The qualitative findings shed light on a range of physical, psychosocial, and existential challenges faced by advanced oesophago-gastric cancer patients. These multiple and often persistent challenges appear to cause considerable distress; however, patients describe the importance of maintaining a sense of normality and control over their illness and its effects. Patients value continuity and structure, however many report shortcomings when accessing care. No findings reporting the experiences from the perspective of carers were found, therefore all findings represent the perspective of the patient.
CONCLUSIONS
Further high-quality research is needed to understand how best to support and manage the palliative care needs of individuals living with advanced oesophago-gastric cancer. Implications for practice are discussed, suggesting that psychosocial interventions, complex symptom management and continuity of care could improve the psychosocial functioning of individuals in this setting.
PRE-REGISTRATION

Review
PURPOSE
This systematic review and meta-analysis aimed to examine the impact of global quality of life (QOL) on mortality risk in patients with cancer, considering cancer type and timepoint of QOL assessment.
METHODS
A systematic search was conducted using Cumulated Index to Nursing and Allied Health Literature, PubMed/MEDLINE, and Scopus databases from inception to December 2022. Observational studies that assessed QOL and examined mortality risk in patients with cancer were extracted. Subgroup analyses were performed for cancer types and timepoints of QOL assessment.
RESULTS
Overall, global QOL was significantly associated with mortality risk (hazard ratio: 1.06, 95% confidence interval: 1.05-1.07; p < 0.00001). A subgroup analysis based on cancer type demonstrated that lung, head and neck, breast, esophagus, colon, prostate, hematologic, liver, gynecologic, stomach, brain, bladder, bone and soft tissue, and mixed type cancers were significantly associated with mortality risk; however, melanoma and pancreatic cancer were not significantly associated with mortality risk. Additionally, global QOL was associated with mortality risk at all timepoints (pretreatment, posttreatment, and palliative phase); pretreatment QOL had the largest impact, followed by posttreatment QOL.
CONCLUSION
These findings provide evidence that QOL is associated with mortality risk in patients with cancer at any timepoint. These results indicate the importance of evaluating the QOL and supportive interventions to improve QOL in any phase.

Review
BACKGROUND
Stomach diseases have become global health concerns. Protoberberine alkaloids (PBAs) are a group of quaternary isoquinoline alkaloids from abundant natural sources and have been shown to improve gastric disorders in preclinical and clinical studies. The finding that PBAs exhibit low oral bioavailability but potent pharmacological activity has attracted great interest.
PURPOSE
This review aims to provide a systematic review of the molecular mechanisms of PBAs in the treatment of gastric disorders and to discuss the current understanding of the pharmacokinetics and toxicity of PBAs.
METHODS
The articles related to PBAs were collected from the Web of Science, Pubmed, and China National Knowledge Infrastructure databases using relevant keywords. The collected articles were screened and categorized according to their research content to focus on the gastroprotective effects, pharmacokinetics, and toxicity of PBAs.
RESULTS
Based on the results of preclinical studies, PBAs have demonstrated therapeutic effects on chronic atrophic gastritis and gastric cancer by activating interleukin-4 (IL-4)/signal transducer and activator of transcription 6 (STAT6) pathway and suppressing transforming growth factor-beta 1 (TGF-β1)/phosphoinositide 3-kinase (PI3K), Janus kinase-2 (JAK2)/signal transducers and activators of transcription 3 (STAT3), and mitogen-activated protein kinase (MAPK) pathways. The major PBAs exhibit similar pharmacokinetic properties, including rapid absorption, slow elimination, and low bioavailability. Notably, the natural organ-targeting property of PBAs may account for the finding of their low blood levels and high pharmacological activity. PBAs interact with other compounds, including conventional drugs and natural products, by modulation of metabolic enzymes and transporters. The potential tissue toxicity of PBAs should be emphasized due to their high tissue accumulation.
CONCLUSION
This review highlights the gastroprotective effects, pharmacokinetics, and toxicity of PBAs and will contribute to the evaluation of drug properties and clinical translational studies of PBAs, accelerating their transfer from the laboratory to the bedside.

Review
The appropriate host cell immune responses for the progression of several diseases, including gastric or stomach cancer (GC), are significantly influenced by HLA polymorphisms. Our objective was to systematically review the evidence linking HLA polymorphisms with the risk of Helicobacter. pylori related GC. We conducted a comprehensive literature search to identify studies published between 2000 and April 2023 on the association of HLA polymorphisms with H. pylori related GC using databases such as Medline through PubMed, Embase, Web of Science (core collection), The Cochrane Library, and Scopus. Two authors independently screened articles, extracted data, and assessed the risk of bias using the Risk of Bias Assessment tool for Non-randomized Studies. From 7872 retrieved studies, 19 met inclusion criteria, encompassing 1656 cases and 16,787 controls across four World Health Organization regions, with Japan contributing the most studies. We explored HLA-A/B/C, HLA-DRB1/DQA1/DQB1, HLA-G, and MICA alleles. Of 29 significant HLA polymorphisms identified, 18 showed a positive association with GC, whereas 11 were negatively associated. HLA-DQB1*06 allele was most frequently associated to susceptibility, as reported in four studies, followed by HLA-DRB1*04 and HLA-DQA1*01, each reported in two studies. Conversely, HLA-G*01, HLA-DQA1*01, HLA-DQA1*05, and HLA-DQB1*03 were identified as protective in two studies each. Additionally, five genotypes and six haplotypes were reported as positive, whereas three genotypes and two haplotypes were negative factors for the disease incidence or mortality. Despite heterogeneity in the study population and types of HLA polymorphisms examined, our analysis indicates certain polymorphisms are associated with H. pylori related GC progression and mortality in specific populations.

Meta-Analysis Review
OBJECTIVE
Extensive research has explored the link between saturated fatty acids (SFAs) and cardiovascular diseases, alongside other biological dysfunctions. Yet, their association with cancer risk remains a topic of debate among scholars. The present study aimed to elucidate this association through a robust meta-analysis.
METHODS
PubMed, Embase, Cochrane Library, and Web of Science databases were searched systematically to identify relevant studies published until December 2023. The Newcastle-Ottawa Scale was used as the primary metric for evaluating the quality of the included studies. Further, fixed- or random-effects models were adopted to determine the ORs and the associated confidence intervals using the Stata15.1 software. The subsequent subgroup analysis revealed the source of detection and the cancer types, accompanied by sensitivity analyses and publication bias evaluations.
RESULTS
The meta-analysis incorporated 55 studies, comprising 38 case-control studies and 17 cohort studies. It revealed a significant positive correlation between elevated levels of total SFAs and the cancer risk (OR of 1.294; 95% CI: 1.182-1.416; P-value less than 0.001). Moreover, elevated levels of C14:0, C16:0, and C18:0 were implicated in the augmentation of the risk of cancer. However, no statistically significant correlation of the risk of cancer was observed with the elevated levels of C4:0, C6:0, C8:0, C10:0, C12:0, C15:0, C17:0, C20:0, C22:0, and C24:0. Subgroup analysis showed a significant relationship between excessive dietary SFA intake, elevated blood SFA levels, and heightened cancer risk. Increased total SFA levels correlated with higher risks of breast, prostate, and colorectal cancers, but not with lung, pancreatic, ovarian, or stomach cancers.
CONCLUSION
High total SFA levels were correlated with an increased cancer risk, particularly affecting breast, prostate, and colorectal cancers. Higher levels of specific SFA subtypes (C14:0, C16:0, and C18:0) are also linked to an increased cancer risk. The findings of the present study would assist in providing dietary recommendations for cancer prevention, thereby contributing to the development of potential strategies for clinical trials in which diet-related interventions would be used in combination with immunotherapy to alter the levels of SFAs in patients and thereby improve the outcomes in cancer patients. Nonetheless, further high-quality studies are warranted to confirm these associations.

Review
, a plant in the Orchidaceae family, has been used in traditional Chinese medicine for thousands of years. Sweet and slightly cold in nature, it can invigorate the stomach, promote fluid production, nourish Yin, and dissipate heat. Over the past decade, more than 60 compounds have been derived from , including flavonoids, bibenzyl, and phenanthrene. Various studies have explored the underlying pharmacological mechanisms of these compounds, which have shown antitumor, hypoglycemic, hypertensive, gastrointestinal-regulatory, visceral organ protection, antiaging, and neurorestorative effects. This paper presents a systematic review of the structural classification, biological activity, and pharmacological mechanisms of different chemical components obtained from over the past decade. This review aims to provide a reference for future study and establish a foundation for clinical applications. Furthermore, this review identifies potential shortcomings in current research as well as potential directions and methodologies in future plant research.

Review
From a global perspective, gastric cancer (GC) persists as a significant healthcare issue. In the Western world, the majority of cases are discovered at late stages, when the treatment is generally unsuccessful. There are no organized screening programs outside of Asia (Japan and Republic of Korea). Traditional diagnosis techniques (such as upper endoscopy), conventional tumor markers (CEA, CA19-9, and CA72-4), radiographic imaging, and CT scanning all have drawbacks. The gold standard for the earliest detection of cancer and related premalignant lesions is still endoscopy with a proper biopsy follow-up. Since there are currently no clinically approved biomarkers for the early diagnosis of GC, the identification of non-invasive biomarkers is expected to help improve the prognosis and survival rate of these patients. The search for new screening biomarkers is currently underway. These include genetic biomarkers, such as circulating tumor cells, microRNAs, and exosomes, as well as metabolic biomarkers obtained from biofluids. Meanwhile, cutting-edge high-resolution endoscopic technologies are demonstrating promising outcomes in the visual diagnosis of mucosal lesions with the aid of linked color imaging and machine learning models. Following the PRISMA guidelines, this study examined the articles in databases such as PubMed, resulting in 167 included articles. This review discusses the currently available and emerging methods for diagnosing GC early on, as well as new developments in the endoscopic detection of early lesions of the stomach.
