Helicobacter pylori (H. pylori) infection can cause multiple secondary digestive disorders. Some studies have found that polymorphisms in Toll-like receptor (TLR) genes, including TLR10 rs10004195, may be associated with increased susceptibility to H. pylori infection. Despite conflicting reports, we conducted a meta-analysis to clarify the relationship between these factors.

We conducted an exhaustive review, encompassing all relevant literature up to February 2024, using databases such as PubMed, Embase, Web of Science, and the China National Knowledge Infrastructure. We screened studies based on specific criteria and evaluated their quality using the Newcastle-Ottawa scale. Heterogeneity testing and meta-analysis were performed using Stata 17.0 software, and SPSSAU was used for publication bias evaluation and sensitivity analysis.

Eight of the 487 identified studies met the inclusion criteria, comprising 3,004 and 2,140 individuals in the H. pylori-positive and negative control groups, respectively. Our results demonstrated that individuals carrying the AA genotype at the TLR10 rs10004195 locus had a significantly increased likelihood of H. pylori infection when analyzed using the recessive genetic model (OR: 1.64, CI: 1.04–2.58, p = 0.034). No statistically significant associations were found in the other four genetic models.

Our findings suggest that carrying the TLR10 rs10004195 AA genotype is associated with a significantly elevated risk of H. pylori infection. This information could be used to assess future risk of H. pylori infection in healthy individuals and provide personalized health guidance based on individual genetic polymorphisms.

Balamuthia mandrillaris is a free-living amoeba that can cause granulomatous amoebic encephalitis, a lethal neurological condition in humans. This pathogen infects not only immunocompromised hosts but, more commonly, immunocompetent individuals. Balamuthia mandrillaris mainly infects the skin and nervous system. When it affects the nervous system, it can manifest as Balamuthia mandrillaris encephalitis (BAE). This article presents a case of BAE in central China, diagnosed through next-generation sequencing and histopathology. The patient is a 64-year-old male who was admitted to the Department of Neurosurgery with a one-week history of headache. Magnetic resonance imaging scans revealed a mass in the right temporal-occipital region, and postoperative pathological examination confirmed that the lesion was BAE. We will detail the clinical course of this disease in this patient, aiming to enhance clinicians’ understanding of Balamuthia mandrillaris infections.

Gastrointestinal endoscopy has revolutionized the entire practice of gastroenterology worldwide, including Nigeria. Endoscopy was introduced in Nigeria more than four decades ago, and it has been a story of varying successes and challenges. This study explored the various experiences of endoscopists, the challenges they face, and the efforts put in place to maintain the practice in Nigeria.

This cross-sectional survey was conducted from October to December 2023 among endoscopists practicing in Nigeria. It involved a 30-part self-administered online questionnaire that inquired about individual experiences in endoscopy practice. These included qualifications, competency, facility settings, challenges faced, and innovations employed to address them. At the end of the survey, responses were analyzed using descriptive statistics, Chi-square, and likelihood ratios at the 0.05 level of significance.

A total of 41 respondents participated in the survey from 19 states across the six geopolitical zones of Nigeria, with a mean age ± standard deviation of 43 ± 7 years. Male respondents made up 80.5%, with Nigerian-trained gastroenterologists via the residency program constituting the predominant population, and an average endoscopy experience of five to nine years (39.02%). Most of the respondents work in public institutions (73.17%), with 43.9% working in at least two centers. There was an average of five endoscopists and three to seven endoscopy centers per state. Most centers perform 11–12 upper and four to five lower GI endoscopies per week, respectively, with a predominance of diagnostic procedures. The most common endoscopic intervention was variceal band ligation. The most common challenge faced was the high cost of procedures, accessories, and maintenance of endoscopes.

Endoscopy practice cuts across all the zones and most states of the federation. Both diagnostic and therapeutic procedures are available in most centers. However, the practice is faced with a myriad of challenges, mainly poor financing and inadequate training, among others. As a result, some innovations were locally developed to ease the practice and prevent it from collapsing.

Mitochondria are highly dynamic organelles that adapt to cellular stress and metabolic demands through processes such as fission, fusion, mitophagy, and transport, all of which are vital for maintaining cellular signaling and metabolic homeostasis. Fission facilitates mitochondrial division and biogenesis, while fusion enhances mitochondrial fitness and metabolic flexibility by mitigating damage. Together, these processes play a critical role in regulating cellular stress responses and apoptosis. Dysregulation of mitochondrial dynamics has been linked to impaired development and cancer progression, including breast cancer metastasis. A comprehensive understanding of mitochondrial dynamics in breast cancer progression is essential for advancing precision medicine. This review delves into the intricate molecular mechanisms governing mitochondrial biogenesis, fission, fusion, and mitophagy, with a particular focus on the role of mitophagy in maintaining mitochondrial homeostasis and its connection to metastasis progression. Furthermore, it discusses potential therapeutic strategies targeting mitochondrial dynamics and highlights the critical steps necessary to translate these approaches into clinical trials.

Intrahepatic cholangiocarcinoma (iCCA) is the second most prevalent primary liver cancer, characterized by insidious onset and high malignancy. Many patients are diagnosed at an inoperable stage, and the effectiveness of chemotherapy and radiotherapy remains limited. This study aimed to provide a comprehensive review of the histological classification, genetic alterations, molecular subtypes, and corresponding imaging signatures of iCCA, highlighting its heterogeneity and offering insights into targeted therapy and personalized treatment. The heterogeneity of iCCA poses significant challenges to both targeted therapy and immunotherapy, necessitating in-depth exploration at the molecular and subtyping levels. Investigating genetic variations, signaling pathway alterations, and molecular subtypes can aid in patient stratification. Stratifying iCCA patients allows for more precise treatment selection, ultimately improving survival outcomes. Imaging, as a non-invasive tool, holds substantial potential for predicting subtypes and molecular profiles. It is possible to infer histological and molecular features from imaging, or to interpret imaging signatures in light of known histological and molecular data. This integrative approach, combining external imaging with internal molecular insights, fosters a comprehensive understanding of iCCA’s characteristics and enhances clinical management.

Paget’s disease of the esophagus is extremely rare, with few cases reported. In this report, we describe a case of recurrent esophageal Paget’s disease coexisting with small cell carcinoma. A 63-year-old man presented with the chief complaint of a rediscovered early esophageal cancer. Endoscopic examination revealed two separate superficial flat tumors in the upper and mid esophagus. Endoscopic submucosal dissection was performed, diagnosing diffuse Paget’s disease (5.5 × 3.5 cm) and a small focus on intramucosal squamous cell carcinoma, respectively. Paget’s cells were also found in the distal and right margins of the first specimen of endoscopic submucosal dissection. Immunohistochemical analysis showed that Paget’s disease diffusely expressed cytokeratin 7 (CK7), CK18, and mucin 6 (MUC6), and focally expressed CD56 and chromogranin A, but not CK5/6, p63, p40, MUC5AC, MUC2, or synaptophysin. A complete absence of p53 and Rb1 was observed in Paget’s disease. However, overexpression of p53 and retention of Rb1 were seen in squamous cell carcinoma. Approximately 27 months later, a prominent tumor was found at the same location as the previous Paget’s disease. Subsequently, radical surgery was performed, and the final pathological evaluation revealed esophageal small cell carcinoma coexisting with Paget’s disease. Moreover, both p53 and Rb1 were completely absent in both Paget’s disease and the small cell carcinoma. This suggests that esophageal Paget’s disease may dedifferentiate and develop into small cell carcinoma. In conclusion, esophageal Paget’s disease can co-occur with invasive carcinomas, including small cell carcinoma, and should be completely resected endoscopically, with close follow-up.

Proper nutritional management has been shown to reduce complications and lead to better clinical outcomes. However, inaccurate nutritional screening and assessment, inappropriate nutrition support, and deviations from suggested guidelines were observed in clinical practice. We aimed to investigate the nutritional status and support of hospitalized patients with neurological diseases to identify deficiencies in nutritional assessment and treatment.

A self-designed questionnaire, developed through a literature review, group discussions, and expert consultation, was converted into an electronic form to conduct a cross-sectional survey in a tertiary-level general hospital. The patients’ basic information and the first nutrition assessment were filled out upon admission. The final nutrition assessment were logged at discharge, transfer out, or death. Two-person cross-entry was used to ensure the accuracy of data input.

A total of 620 patients were enrolled in this study. Of these, 24.4% were at nutritional risk upon admission, and 22.7% were identified as at nutritional risk in the final assessment. There were no statistically significant differences in nutritional status between the first and final assessments, except for serum albumin concentration. A total of 118 patients (19.0%) received nutrition therapy. Complications occurred in 35 (45.5%) patients treated with enteral nutrition and 29 (30.5%) patients treated with parenteral nutrition.

The incidence of nutritional risk in inpatients with neurological diseases enrolled in this study was relatively low. However, nutritional treatment in this study was not sufficiently standardized. Nurses are needed to receive relevant professional training to improve quality of nutritional interventions.

Diagnosing and treating cytopenic myelofibrosis in children is challenging due to the wide spectrum of clinical and pathological features, underlying etiologies, and variable therapeutic responses. In this review, we summarize the related literature and present our diagnostic algorithm to differentiate pediatric myelofibrosis and guide therapy. In brief, primary myelofibrosis is extremely rare in children, while myelofibrosis secondary to non-neoplastic or neoplastic disorders should be thoroughly ruled out in ambiguous cases. Moreover, it is reasonable to closely follow up patients and repeat bone marrow biopsy before reaching a definitive diagnosis.

Escalating antimicrobial resistance is a global threat, emphasizing the need to explore alternative treatment options. Hence, we aimed to explore the in-vitro activity of ceftazidime-avibactam (CAZ-AVI) in clinical isolates of carbapenem-resistant gram-negative bacteria.

This was an observational, cross-sectional study conducted at the Microbiology Department of Indus Hospital, Karachi, Pakistan, from January 2023 to October 2024. Carbapenem-resistant gram-negative rods isolated from clinical specimens received from the outpatient, emergency, and inpatient departments were included. Consecutive, non-probability sampling was employed for the collection of isolates. Identification of the organisms was confirmed using API® ID strips, and antimicrobial susceptibility for carbapenems and CAZ-AVI was determined via the Kirby-Bauer disc diffusion method.

A total of 158 bacterial isolates were characterized as carbapenem-resistant. Of these, 92 (58%) were Enterobacterales, and 66 (42%) were Pseudomonas aeruginosa. CAZ-AVI was susceptible in 17 (11%) of the isolates, of which four (24%) were Klebsiella spp. and Escherichia coli each, and nine (52%) were P. aeruginosa. CAZ-AVI-susceptible strains were predominant among patients aged 26–50 years (n = 6; 35%), most of whom were females (n = 10; 59%) and inpatients (n = 8; 47%). Clinical samples from patients with urinary tract infections grew the most CAZ-AVI-susceptible strains (n = 9; 53%).

Our study demonstrated low CAZ-AVI susceptibility in our carbapenem-resistant gram-negative bacterial strains. Understanding regional antimicrobial patterns in multidrug-resistant bacteria is crucial for the effective use of CAZ-AVI, along with the strict implementation of strategies for controlling antimicrobial resistance.

China has made remarkable progress in controlling chronic hepatitis B virus (HBV) infection over the past three decades. The prevalence of hepatitis B surface antigen has declined from 9.72% in 1992 to 5.86% in 2020, with a striking reduction from 9.67% to 0.30% among children under five. Universal hepatitis B vaccination has been pivotal, preventing more than 40 million infections and seven million HBV-related deaths since 1992. Nevertheless, an estimated 75 million individuals are currently living with chronic HBV infection in China. Among them, only 59.78% are aware of their infection status, and about 30 million remain undiagnosed. Of those diagnosed, 38.25% (approximately 17 million) meet the criteria for antiviral treatment, yet only 17.33% (about three million) are receiving treatment. To accelerate progress toward the World Health Organization’s elimination targets, China has updated its clinical guidelines to expand treatment eligibility and improve diagnosis and treatment coverage. Moreover, Chinese pharmaceutical companies and academic institutions are actively engaged in developing novel therapies with promising efficacy, aiming to achieve a functional cure. China’s holistic approach, combining evidence-based public health interventions with active clinical management and innovative pharmaceutical development, provides valuable experience for global HBV elimination initiatives. This review aimed to summarize China's progress in HBV control, identify remaining gaps in diagnosis and treatment, and highlight strategic approaches, including public health interventions, clinical policy updates, and pharmaceutical innovation, toward achieving HBV elimination.
