Meta-Analysis Review
This study aims to investigate the impact of antithrombotic agents and proton-pump inhibitors (PPIs) on fecal immunochemical test (FIT). PubMed, EMBASE, Web of Science, Cochrane Central, and Google Scholar were searched from inception until September 3, 2023. Studies comparing the diagnostic performance of FIT between medicine users and non-users in average-risk colorectal cancer screening populations were included. Pooled sensitivity, specificity, and positive predictive values (PPVs) for advanced neoplasia (AN) of FIT were compared by reporting pooled odds ratios (ORs) with 95% confidence intervals (CIs) using a random-effects model. Twenty-two studies enrolling 5,572,367 individuals were included. For aspirin, pooled sensitivity and specificity for AN were 57.2% and 88.4% in users versus 60.2% and 93.2% in non-users; while pooled ORs were 1.49 (95% CI 0.89-2.48, P = 0.13) and 0.72 (95% CI 0.62-0.83, P < 0.001), respectively. In subgroup analysis, there was no difference in sensitivity and specificity between the two groups at the cutoff of 20 μg Hb/g (P = 0.57 and 0.29, respectively) but a significantly lower specificity in users compared with non-users at lower cutoffs (P < 0.001). Moreover, a significantly lower PPV in users compared with non-users was observed after matching age and sex confounders (P = 0.001). Warfarin had no significant influence on PPV of FIT (P = 0.43). PPIs were associated with a significantly lower PPV in users (P < 0.001). Aspirin use was associated with lower specificity and PPV of FIT. Aspirin discontinuation before FIT to reduce false-positive results should be interpreted with caution given concerns about cardiovascular events. Increasing cutoff values of FIT in aspirin users may be another possible approach. Additionally, warfarin withdrawal before FIT is unnecessary but PPIs withdrawal before FIT is recommended to reduce false-positive results.

Meta-Analysis
BACKGROUND AND AIMS
Acid-suppressive drugs (ASDs) are widely used in many gastric acid-associated diseases. Nocturnal acid breakthrough has been a common problem of many ASDs, such as proton-pump inhibitors (PPIs) and H -receptor antagonists (H2RAs). Potassium-competitive acid blockers (P-CABs) are expected to solve this continuing conundrum. This article examined major ASDs and compared them with placebo in terms of nocturnal acid-inhibitory effects, using a network meta-analysis of randomized controlled trials (RCTs).
METHODS
To compare the effectiveness of major ASDs, a Bayesian network meta-analysis (NMA) was applied to process data extracted from RCTs. The plausible ranking for each regimen and some subgroups were assessed by surface under the cumulative ranking curves (SUCRA).
RESULTS
Fifty-five RCTs were conducted with 2015 participants. In terms of nocturnal acid-inhibitory effects, the overall results showed that tegoprazan (SUCRA 91.8%) and vonoprazan (SUCRA 91.0%) had the best performance, followed by new PPIs (including tenatoprazole and ilaprazole) (SUCRA 76.6%), additional H2RAs once at bedtime (AHB) (SUCRA 61.3%), isomer PPIs (including esomeprazole and dexlansoprazole) (SUCRA 38.6%), revaprazan (SUCRA 34.7%), traditional PPIs (including omeprazole, rabeprazole, pantoprazole, lansoprazole) (SUCRA 32.6%), H2RAs (SUCRA 23.1%), and placebo (SUCRA 0.3%). In some subgroups, the nocturnal acid-inhibitory effect of vonoprazan or tegoprazan was better than most of the other regimens, even new PPIs and AHB.
CONCLUSIONS
This is the first study to compare the effect of ASDs on inhibiting nocturnal acid breakthrough. Overall, in terms of nocturnal acid-inhibitory effect, vonoprazan and tegoprazan had an advantage against other regimens including H2RAs, isomer PPIs, traditional PPIs, AHB, and new PPIs. Even in some subgroups, such as language classification (English), types of study design (crossover-RCT), age (≤40 years), BMI (18.5-24.9 kg/m ), continent (Asia and North America), disease status (health), the duration of therapy (2 weeks), and time of administration (at daytime or at night-time), the nocturnal acid-inhibitory effect of vonoprazan or tegoprazan were better than most regimens, even AHB and new PPIs.

INTRODUCTION
Head and neck cancer ranks as the seventh most common cancer worldwide. Proton therapy is widely used in head and neck cancer. Osteoradionecrosis(ORN) is currently a commonly investigated side effect of proton therapy. A meta-analysis is needed to investigate this topic.
MATERIAL/METHODS
Two authors searched three databases, including PubMed, Embase, and Cochrane Library; the search period was from inception to June 2023. The search keyword was set to be ((("osteoradionecrosis") OR ("osteonecrosis")) AND ("proton")).
RESULTS
We initially collected 410 articles, and after article selections, 22 articles remained in our systematic reviews. Due to the overlapping of patient populations, 17 studies were finally included in our meta-analysis. The pooled grade 3 or more ORN rate is 0.01(95 % CI = 0.01-0.03). Subgroup analysis showed that IMPT didn't reduce grade 3 or more ORN compared with 3DCPT (p = 0.15).
CONCLUSIONS
Our meta-analysis showed that severe ORN rarely occurred in proton therapy for head and neck cancer patients.

Meta-Analysis
BACKGROUND
Several studies have suggested that the mucosal protective effects of proton pump inhibitors (PPIs) do not extend beyond the duodenum; however, PPIs may cause lower gastrointestinal (LGI) injury, although these relationships have not yet been fully elucidated.
METHODS
We searched all the relevant studies published until September 2022 that examined the risk of PPIs for LGI bleeding. We performed a meta-analysis of the risk of LGI bleeding (small bowel (SB) or colorectal bleeding) between PPI users and non-users. A subgroup analysis of patients consuming aspirin or nonsteroidal anti-inflammatory drugs (NSAIDs) was also performed.
RESULTS
Twelve studies with 341,063 participants were included in this meta-analysis. The use of PPIs was associated with the risk of LGI bleeding (odds ratio [OR] [95% confidence interval [CI]] = 1.42 [1.16-1.73]; hazard ratio [HR] [95% CI] = 3.23 [1.56-6.71]). An association between PPI use and the risk of LGI bleeding was also identified in the subgroup of aspirin or NSAID users (OR [95% CI] = 1.64 [1.49-1.80]; HR [95% CI] = 6.55 [2.01-21.33]). In the bleeding site-specific analyses, the risk of SB bleeding was associated with PPI use (OR [95% CI] = 1.54 [1.30-1.84]).
CONCLUSIONS
PPI use was associated with an increased risk of LGI bleeding, particularly SB bleeding. This association was particularly pronounced among aspirin and NSAID users. Inappropriate PPI prescriptions should be avoided in patients with LGI bleeding and a low risk of upper gastrointestinal disease.

Meta-Analysis
BACKGROUND
() infects over half the global population, causing gastrointestinal diseases like dyspepsia, gastritis, duodenitis, peptic ulcers, G-MALT lymphoma, and gastric adenocarcinoma. Eradicating is crucial for treating and preventing these conditions. While conventional proton pump inhibitor (PPI)-based triple therapy is effective, there's growing interest in longer acid suppression therapies. Potassium competitive acid blocker (P-CAB) triple and dual therapy are new regimens for eradication. Initially used in Asian populations, vonoprazan (VPZ) has been recently Food and Drug Administration-approved for eradication.
AIM
To assess the efficacy of regimens containing P-CABs in eradicating infection.
METHODS
This study, following PRISMA 2020 guidelines, conducted a systematic review and meta-analysis by searching MEDLINE and Scopus libraries for randomized clinical trials (RCTs) or observational studies with the following command: [("" OR "H pylori") AND ("Treatment" OR "Therapy" OR "Eradication") AND ("Vonaprazan" OR "Potassium-Competitive Acid Blocker" OR "P-CAB" OR "PCAB" OR "Revaprazan" OR "Linaprazan" OR "Soraprazan" OR "Tegoprazan")]. Studies comparing the efficacy of P-CABs-based treatment to classical PPIs in eradicating were included. Exclusion criteria included case reports, case series, unpublished trials, or conference abstracts. Data variables encompassed age, diagnosis method, sample sizes, study duration, intervention and control, and eradication method were gathered by two independent reviewers. Meta-analysis was performed in R software, and forest plots were generated.
RESULTS
A total of 256 references were initially retrieved through the search command. Ultimately, fifteen studies (7 RCTs, 7 retrospective observational studies, and 1 comparative unique study) were included, comparing P-CAB triple therapy to PPI triple therapy. The intention-to-treat analysis involved 8049 patients, with 4471 in the P-CAB intervention group and 3578 in the PPI control group across these studies. The analysis revealed a significant difference in eradication between VPZ triple therapy and PPI triple therapy in both RCTs and observational studies [risk ratio (RR) = 1.17, 95% confidence interval (CI): 1.11-1.22, < 0.0001] and (RR = 1.13, 95%CI: 1.09-1.17, < 0.0001], respectively. However, no significant difference was found between tegoprazan (TPZ) triple therapy and PPI triple therapy in both RCTs and observational studies (RR = 1.04, 95%CI: 0.93-1.16, = 0.5) and (RR = 1.03, 95%CI: 0.97-1.10, = 0.3), respectively.
CONCLUSION
VPZ-based triple therapy outperformed conventional PPI-based triple therapy in eradicating , positioning it as a highly effective first-line regimen. Additionally, TPZ-based triple therapy was non-inferior to classical PPI triple therapy.

Meta-Analysis Review
BACKGROUND
Advances in cancer treatments, particularly the development of radiation therapy, have led to improvements in survival outcomes in children with brain tumors. However, radiation therapy is associated with significant long-term neurocognitive morbidity. The present systematic review and meta-analysis aimed to compare the neurocognitive outcomes of children and adolescents with brain tumors treated with photon radiation (XRT) or proton therapy (PBRT).
METHODS
A systematic search was conducted (PubMed, Embase, Cochrane, and Web of Science from inception until 02/01/2022) for studies comparing the neurocognitive outcomes of children and adolescents with brain tumors treated with XRT vs. PBRT. The pooled mean differences (expressed as Z scores) were calculated using a random effects method for those endpoints analyzed by a minimum of three studies.
RESULTS
Totally 10 studies (n = 630 patients, average age range: 1-20 years) met the inclusion criteria. Patients who had received PBRT achieved significantly higher scores (difference in Z scores ranging from 0.29-0.75, all P < 0.05 and significant in sensitivity analyses) after treatment than those who had received XRT for most analyzed neurocognitive outcomes (i.e., intelligence quotient, verbal comprehension and perceptual reasoning indices, visual motor integration, and verbal memory). No robust significant differences (P > 0.05 in main analyses or sensitivity analyses) were found for nonverbal memory, verbal working memory and working memory index, processing speed index, or focused attention.
CONCLUSIONS
Pediatric brain tumor patients who receive PBRT achieve significantly higher scores on most neurocognitive outcomes than those who receive XRT. Larger studies with long-term follow-ups are needed to confirm these results.

Review
AIMS
Aim of the present analysis was to report results of a systematic review of the literature in the setting of patients treated with hypoF PT for benign lesions of the central nervous system (CNS).
METHODS
The methodology complied with the PRISMA recommendations. PubMed, EMBASE and Scopus databases were interrogated in September 2022.
RESULTS
Twelve papers have been selected including patients treated for base of the skull meningiomas (6 papers), vestibular schwannoma (3 papers) and pituitary adenomas (3 papers). Clinical outcomes were evaluated with both radiologic images and clinical parameters. Long-term toxicity was reported in all but one series with an incidence ranging from 2 % to 7 % in patients treated for base of skull meningioma and 1-9 % for schwannoma.
CONCLUSIONS
HypoF PT is a safe and effective treatment in selected benign tumors of the CNS. Further dosimetric and clinical comparisons are required to better refine the patients' selection criteria.

Meta-Analysis
BACKGROUND
Over the last few decades, reflux diseases, such as laryngopharyngeal reflux (LPR) and gastroesophageal reflux disease (GERD), have been identified as significant contributors to inflammatory upper aerodigestive tract diseases. Establishing a direct relationship between reflux disease and chronic rhinosinusitis (CRS) is challenging due to the high prevalence of both diseases and their potential for independent coexistence.
OBJECTIVE
The purpose of this study is to review the existing literature and evaluate the evidence of an association between reflux diseases and CRS.
METHODS
A comprehensive electronic search was conducted across multiple databases to identify all studies that investigated the relationship between LPR, GERD, and CRS from January 1, 1950, to June 16, 2022. Only studies with English manuscripts involving adult populations were included, while case series, case reports, and in vitro studies were excluded. The risk of bias was evaluated using The Newcastle-Ottawa Scale for case-control studies and the NIH quality assessment tool for observational cohort and cross-sectional studies.
RESULTS
The search strategy yielded a total of 427 articles, out of which 25 studies examined the correlation between reflux diseases and CRS. The meta-analysis indicated a significant association between the presence of GERD and CRS compared to control groups ( < .001; CI 3.56 [2.25, 5.65]), as well as significantly higher pH values and pepsin detection in CRS patients when compared to healthy individuals ( = .003). Furthermore, all studies that evaluated proton pump inhibitor (PPI) therapy in CRS patients reported positive outcomes, with 93% of CRS patients showing improvement on PPIs.
CONCLUSION
The existing literature provides suggestive evidence of an association between reflux diseases and CRS, with regards to both prevalence and treatment. Nonetheless, further studies are required to confirm this relationship.

Review
The increasing number of MRI studies focused on prodromal Parkinson's Disease (PD) demonstrates a strong interest in identifying early biomarkers capable of monitoring neurodegeneration. In this systematic review, we present the latest information regarding the most promising MRI markers of neurodegeneration in relation to the most specific prodromal symptoms of PD, namely isolated rapid eye movement (REM) sleep behavior disorder (iRBD). We reviewed structural, diffusion, functional, iron-sensitive, neuro-melanin-sensitive MRI, and proton magnetic resonance spectroscopy studies conducted between 2000 and 2023, which yielded a total of 77 relevant papers. Among these markers, iron and neuromelanin emerged as the most robust and promising indicators for early neurodegenerative processes in iRBD. Atrophy was observed in several regions, including the frontal and temporal cortices, limbic cortices, and basal ganglia, suggesting that neurodegenerative processes had been underway for some time. Diffusion and functional MRI produced heterogeneous yet intriguing results. Additionally, reduced glymphatic clearance function was reported. Technological advancements, such as the development of ultra-high field MRI, have enabled the exploration of minute anatomical structures and the detection of previously undetectable anomalies. The race to achieve early detection of neurodegeneration is well underway.

Review
BACKGROUND
Proton-pump inhibitors (PPI) are frequently used in the emergency and general practice settings in several clinical presentations linked to acute upper gastro-intestinal tract disorders as abdominal or chest pain without recommendations.
OBJECTIVE
The aim of this scoping review was to assess pain reduction, diagnostic performance, and safety in the first 24 h-management in primary care or emergency medicine.
METHODS
Search was realized by 2 independent reviewers in PubMed, Embase, and Web of Science following PRISMA-ScR guidelines. Only original articles or systematic reviews in English were included. Studies about chronic and/or bleeding conditions, therapeutic cocktails and studies without pain evaluation were excluded. Two methodologies were used for bias estimation.
RESULTS
From 4442 titles, 79 full-text articles were assessed, and 9 were included. There is no strong evidence supporting the use of PPI as a first line analgesic or diagnostic test in acute syndromes linked to acute upper gastro-intestinal tract disorder. A small effect in pain reduction was retrieved in patients with low pain scores. A poor additional value in patients with gastric reflux, and a low specificity compared to other diagnostic tests were observed. A short-term PPI administration appears to be safe with low risk of serious allergic reactions, and poor adverse effects (moderate evidence).
CONCLUSION
Although PPIs may contribute to the multimodal analgesia in acute settings, with few and/or minor side effects, no recommendation can be drawn for their use as a primary analgesic. Data regarding the relevance of the PPI test are much less clear, no data regarding care pathways are available.
