Background: Hepatitis B virus infection is a major public health problem among pregnant women worldwide. Hepatitis B virus is highly infectious and is the most common cause of morbidity and mortality among pregnant women, and evidence is scarce on the pooled seroprevalence of hepatitis B virus in Ethiopia. Objectives: This study aimed to investigate the pooled seroprevalence of hepatitis B virus infection and factors associated with pregnant women in Ethiopia. Design: A systematic review and meta-analysis was employed in accordance with the Preferred Reporting Items for Systematic Reviews. Data sources: Searches were carried out in biomedical databases such as PubMed/Medline, Science Direct, Web of Science, Google Scholar, Hinari, and the Cochrane Library published in English until June 2023. Methods: Observational study designs were selected. Endnote citation manager was used to collect and organize the search outcomes and remove duplicate articles. The data were extracted using a Microsoft Excel spreadsheet and exported to STATA 16.0 software for the analysis. Results: A total of 48 research articles were included in the final analysis. The pooled estimated sero prevalence of hepatitis B virus infection among pregnant women in Ethiopia was 5.78% (95% confidence interval = 5.14, 6.43). History of abortion (odds ratio = 6.56, 95% confidence interval = 4.88, 8.90), history of blood transfusion (odds ratio = 5.74, 95% confidence interval = 4.04, 8.16), history of hospitalization (odds ratio = 5.40, 95% confidence interval = 3.68, 7.94), history of multiple sexual partner (odds ratio = 5.80, 95% confidence interval = 3.71, 9.05), history of surgical procedure (odds ratio = 7.39, 95% confidence interval = 4.16, 13.14), history of tattooing (odds ratio = 4.59, 95% confidence interval = 2.83, 7.43), and history of tooth extraction (odds ratio = 4.46, 95% confidence interval = 2.42, 8.22) were significantly associated with hepatitis B virus infection among pregnant women in Ethiopia. Conclusion: The overall pooled prevalence of hepatitis B virus infection among pregnant women in Ethiopia is relatively high. Having a history of abortion, blood transfusion, hospitalization, multiple sexual partners, surgical procedures, tattooing, and tooth extraction were found to be risk factors for hepatitis B virus. Therefore, extensive screening programs for hepatitis B virus in all pregnant women in Ethiopia are needed to prevent further infection and decrease the vertical transmission caused by the disease.

Objectives: Quality of surgery has recently become an essential topic in the prognosis of colon cancer. Complete mesocolic excision for colon cancer has recently gained popularity with high-quality surgery. Patient specimens after complete mesocolic excision with central vessel ligation procedures have an integrity of the mesocolon and the yield of three fields of lymph node harvest. We apply the glacial acid, absolute ethanol, water, and formaldehyde solution to each specimen based on the Japanese classification of lymph node groups and station numbers. We aim to identify the distribution and status of lymph node metastasis according to each tumor site and some pathological characteristics related to this disease. Methods: A prospective cohort study was performed on 45 laparoscopic complete mesocolic excision surgery patients. Results: 2791 lymph nodes were harvested after complete mesocolic excision surgery. The average number was 62.0 ± 22.3 nodes. The mean tumor size (in the largest dimension) was 4.2 ± 1.8 cm. The average length of the resected bowel segments was 29.1 ± 7.7 cm. There are 63 (2.3%) node metastases in 2791 lymph nodes, in which 17/45 (37.8%) patients had pN(+). The minimum positive node size was 1 mm. The positive pericolic lymph nodes (station 1) accounted for the highest rate, with 53 nodes (1.9%). The number of lymph nodes in young age ⩽60 is more significant than in older. The results were similar, with a more significant node retrieval in the group with a tumor size >4.5 cm and specimen length >25 cm. The number of lymph nodes in lower tumor invasive (pT1,3) was smaller than pT4. Our research shows that the cecum, ascending, and descending colon had greater nodes than others, with a mean number of 78.6, 74.2, and 71.3, respectively. Conclusions: The metastasis and harvested lymph nodes accounted for the highest rate of colon cancer in station 1 and the lowest rate in station 3. The number of retrieved lymph nodes was significantly associated with tumor location, size, specimen length, and patient age.
Effects of semi-immersive virtual reality exercise on the quality of life of community-dwelling older adults: Three-month follow-up of a randomized controlled trial
Authors: Wang Li-Ting 
Published: March 2024

Objective This study aimed to examine the effects of semi-immersive virtual reality (VR)-based exercise on the quality of life of older adults. Methods It used a randomized controlled trial design. Older adults (mean age: 72.16 ± 4.9 years) were randomly assigned to experimental ( n = 48) and control ( n = 50) groups. The experimental group engaged in semi-immersive VR exercise for 75–90 min, twice a week, for 12 weeks and partook in no other intervention between the end of the exercise intervention and follow-up. Control group members did not participate in any similar program during the intervention or follow-up periods. Both groups completed three assessments: at baseline (pre-test), post-intervention (post-test), and 3 months later (follow-up). Quality of life was assessed using the World Health Organization Quality of Life Instrument-Older Adults Module. Results Generalized estimating equation analyses indicated that the experimental group exhibited significant post-intervention improvements in quality of life in terms of sensory ability, autonomy, social participation/isolation, death and dying domain, and overall quality of life scores. However, none of these significant effects were maintained 3 months after exercise intervention cessation. Conclusions Semi-immersive VR exercise may be a feasible strategy toward enhancing the quality of life of older adults. However, the participants’ quality of life was not maintained upon exercise cessation, indicating that older adults need to be encouraged to exercise regularly to maintain a good quality of life. VR may need to be combined with other modes of intervention in the future to facilitate long-term quality-of-life improvement in older adults.

Published: March 2024

Objective: This study aimed to investigate sonographic parameters that could predict 1-month mortality in patients with acute kidney injury (AKI). Materials and Methods: This study was a post-hoc analysis of multi-organ sonographic examinations conducted between August 2020 and July 2021. Adult patients who presented to the emergency department (ED) with AKI were recruited. Multi-organ (lung, cardiac, inferior vena cava, kidney, and bladder) sonographic examinations were performed by emergency physicians and evaluated by a radiologist, cardiologist, and another emergency physician, while being anonymized to the results. Results: There were 165 patients with AKI enrolled in the study, and 40 (24.2%) of them experienced 1-month mortality. Following univariate analyses of 23 sonographic parameters, multivariate regression analysis revealed that diffuse ascites (odds ratio [OR], 3.67; 95% confidence interval [CI]: 1.27–10.61) and left ventricular basal diameter (OR, 0.93; 95% CI: 0.87–0.99) were related with 1-month mortality in patients with AKI. Conclusion: In this cohort of AKI patients, the most powerful sonographic parameter, as a predictor of 1-month mortality, was diffuse ascites. Further clinical studies are needed to validate and refine these diagnostic findings.
Long noncoding RNA GATA2AS influences human erythropoiesis by transcription factor and chromatin landscape modulation

Published: March 2024

Abstract
Long noncoding RNAs (lncRNAs) are extensively expressed in eukaryotic cells and have been revealed to be important for regulating cell differentiation. Many lncRNAs have been found to regulate erythroid differentiation in the mouse. However, given the low sequence conservation of lncRNAs between mouse and human, our understanding of lncRNAs in human erythroid differentiation remains incomplete. lncRNAs are often transcribed opposite to protein coding genes and regulate their expression. Here, we characterized a human erythrocyte-expressed lncRNA, GATA2AS, which is transcribed opposite to erythroid transcription regulator GATA2. GATA2AS is a 2080-bp long, primarily nucleus-localized noncoding RNA that is expressed in erythroid progenitor cells and decreases during differentiation. Knockout of GATA2AS in human HUDEP2 erythroid progenitor cells using CRISPR-Cas9 genome editing to remove the transcription start site accelerated erythroid differentiation and dysregulated erythroblast gene expression. We identified GATA2AS as a novel GATA2 and HBG activator. Chromatin isolation by RNA purification showed that GATA2AS binds to thousands of genomic sites and colocalizes at a subset of sites with erythroid transcription factors including LRF and KLF1. RNA pulldown and RNA immunoprecipitation confirmed interaction between GATA2AS and LRF and KLF1. Chromatin immunoprecipitation sequencing (ChIP-seq) showed that knockout of GATA2AS reduces binding of these transcription factors genome wide. Assay for transposase-accessible chromatin sequencing (ATAC-seq) and H3K27ac ChIP-seq showed that GATA2AS is essential to maintain the chromatin regulatory landscape during erythroid differentiation. Knockdown of GATA2AS in human primary CD34+ cells mimicked results in HUDEP2 cells. Overall, our results implicate human-specific lncRNA GATA2AS as a regulator of erythroid differentiation by influencing erythroid transcription factor binding and the chromatin regulatory landscape.
DVA: predicting the functional impact of single nucleotide missense variants
Authors: Wang Dong , Li Jie , Wang Edwin , Wang Yadong 
Published: March 2024

Abstract
Background
In the past decade, single nucleotide variants (SNVs) have been identified as having a significant relationship with the development and treatment of diseases. Among them, prioritizing missense variants for further functional impact investigation is an essential challenge in the study of common disease and cancer. Although several computational methods have been developed to predict the functional impacts of variants, the predictive ability of these methods is still insufficient in the Mendelian and cancer missense variants.

Results
We present a novel prediction method called the disease-related variant annotation (DVA) method that predicts the effect of missense variants based on a comprehensive feature set of variants, notably, the allele frequency and protein–protein interaction network feature based on graph embedding. Benchmarked against datasets of single nucleotide missense variants, the DVA method outperforms the state-of-the-art methods by up to 0.473 in the area under receiver operating characteristic curve. The results demonstrate that the proposed method can accurately predict the functional impact of single nucleotide missense variants and substantially outperforms existing methods.

Conclusions
DVA is an effective framework for identifying the functional impact of disease missense variants based on a comprehensive feature set. Based on different datasets, DVA shows its generalization ability and robustness, and it also provides innovative ideas for the study of the functional mechanism and impact of SNVs.

Published: March 2024

Abstract
Background
Quality traits are essential determinants of consumer preferences. Dioscorea alata (Greater Yam), is a starchy tuber crop in tropical regions. However, a comprehensive understanding of the genetic basis underlying yam tuber quality remains elusive. To address this knowledge gap, we employed population genomics and candidate gene association approaches to unravel the genetic factors influencing the quality attributes of boiled yam.

Methods and Results
Comparative genomics analysis of 45 plant species revealed numerous novel genes absent in the existing D. alata gene annotation. This approach, adding 48% more genes, significantly enhanced the functional annotation of three crucial metabolic pathways associated with boiled yam quality traits: pentose and glucuronate interconversions, starch and sucrose metabolism, and flavonoid biosynthesis. In addition, the whole-genome sequencing of 127 genotypes identified 27 genes under selection and 22 genes linked to texture, starch content, and color through a candidate gene association analysis. Notably, five genes involved in starch content and cell wall composition, including 1,3-beta Glucan synthase, β-amylase, and Pectin methyl esterase, were common to both approaches and their expression levels were assessed by transcriptomic data.

Conclusions
The analysis of the whole-genome of 127 genotypes of D. alata and the study of three specific pathways allowed the identification of important genes for tuber quality. Our findings provide insights into the genetic basis of yam quality traits and will help the enhancement of yam tuber quality through breeding programs.

Abstract
Background and aim
This study aims to examine the mortality rate and trend of gastrointestinal cancers, particularly gastric cancer, as the leading cause of death among cancers in northern Iran over a 9-year period. In light of the changing incidence and mortality rates of cancer in Iran and around the world, the importance of these diseases in people’s lives, and the necessity of updating and monitoring the trend of cancer mortality, we have decided to report on the mortality trend of gastrointestinal cancers, based on crude and age-standardized rates.

Method
This study is a cross-sectional examination of deaths caused by gastrointestinal cancers in Babol city, Iran, between 2013 and 2021. Data was collected from the cause of death registration and classification system of Babol University of Medical Sciences. Population estimation was obtained from the latest census reports. The crude and age-standardized mortality rates and trends of the cancers were calculated.

Results
Overall, there were 1345 deaths from gastrointestinal cancers with an average age of 69.11 ± 14.25 years. The crude and age-standardized rates of these cancers rose from 24.1 to 20.1 per hundred thousand people in 2012 to 29.5 and 25.5 per hundred thousand people, respectively. This trend became more prevalent significantly with the increase of each decade of age for both men (P-value Trend = 0.002) and women (P-value Trend = 0.012). An analysis of gastrointestinal cancers revealed a decreasing trend for cancers of the small intestine, an increasing trend for cancers of the colon, pancreas, and gallbladder, and a stable trend for the remaining cancers over the study period.

Conclusion
The age-standardized rate and the number of gastrointestinal cancers is rising, highlighting the importance of preventative measures such as screening, increasing public awareness, and appropriate diagnostic methods.
Chronic disseminated candidiasis in a patient with acute leukemia - an illustrative case and brief review for clinicians
Authors: Graeter Allison , Lee Dasom , Handley Guy , Baluch Aliyah , Klinkova Olga 
Published: March 2024

AbstractChronic disseminated candidiasis (CDC) is a severe but rarely seen fungal infection presenting in patients with hematologic malignancies after a prolonged duration of neutropenia. A high index of suspicion is required to diagnose CDC as standard culture workup is often negative. While tissue biopsy is the gold standard of diagnosis, it is frequently avoided in patients with profound cytopenias and increased bleeding risks. A presumptive diagnosis can be made in patients with recent neutropenia, persistent fevers unresponsive to antibiotics, imaging findings of hypoechoic, non-rim enhancing target-like lesions in the spleen and liver, and mycologic evidence. Here, we describe the case of an 18-year-old woman with relapsed B-cell acute lymphoblastic leukemia treated with re-induction chemotherapy who subsequently developed CDC with multi-organ involvement. The diagnosis was made based on clinical and radiologic features with positive tissue culture from a skin nodule and hepatic lesion. The patient was treated for a total course of 11 months with anti-fungal therapy, most notably amphotericin B and micafungin, and splenectomy. After initial diagnosis, the patient was monitored with monthly CT abdomen imaging that showed disease control after 5 months of anti-fungal therapy and splenectomy. The diagnosis, treatment, and common challenges of CDC are outlined here to assist with better understanding, diagnosis, and treatment of this rare condition.

Abstract
Background
Coronavirus disease 2019 (COVID-19) has become a global health issue with various effects on the physical and mental state of the societies. The aim of this study was to identify the demographic characteristics and mental health condition of Tehran Municipality employees during the COVID-19 pandemic.

Methods
This cross-sectional study was performed on Tehran Municipality employees in 2020–2021. Participants were selected using stratified random sampling and were divided into COVID-19 and uninfected groups. Demographic characteristics, COVID-19 risk behaviors, General Health Questionnaire-28 (GHQ-28), and Well- Being Social Inventory were filled for all participants.

Results
A total of 510 participants (363 uninfected participants and 147 participants with COVID-19) were evaluated. The prevalence of female gender was significantly higher in COVID-19 group compared to uninfected group (p < 0.001). There was a significant difference between groups in terms of education level (p < 0.001), prevalence of excess weight (p < 0.001), and working sector (p < 0.001). The uninfected group mainly had low contact with clients (p < 0.001) and few underlying diseases (p = 0.004) compared to the COVID-19 group. The mean GHQ-28 and Well- Being Social Inventory were significantly higher in the uninfected group compared to the COVID-19 group (p = 0.002 and p < 0.001, respectively). The prevalence of no and low contact level was significantly higher in the high infection cluster compared to moderate and low infection clusters (p = 0.024).

Conclusions
The findings of this study indicated that all workers should be educated about the significance of social distancing and follow the recommendations regardless of their level of contact with clients.

Authors: Ruan Wenjing , Xu Jing , Yang Fan , Wu Xiaohong , Ying Kejing 
Published: March 2024

Abstract
Background
Immune dysregulation in individuals with long COVID has been detected. Differential diagnosis of diffuse infiltration on chest CT in long COVID is challenging.

Case presentation
A 62-year-old man presented with a 10-month history of dyspnea after COVID-19 infection. Dyspnea became worse in the one month preceding presentation. The chest CT showed multifocal, subpleural, bilateral opacities due to long-COVID, and infiltration around the bronchovascular bundle in the bilateral lower lung field. The pathology for the transbronchial cryobiopsy (TBCB) first reported chronic inflammation (mainly interstitial pneumonia). The patient had positive results on tests for the antibody, RO-52+, EJ+. The presumptive diagnosis of connective tissue disease-interstitial lung disease was made. Prednisone and cyclophosphamide were given. At follow-up one month later, the chest CT showed new diffuse ground-glass infiltration. The previous TBCB specimen was re-evaluated. Foamy macrophages were found in the alveolar air space. Periodic acid-Schiff (PAS) staining was performed. Numerous intracytoplasmic organisms were detected, with morphologic features consistent with those of Tropheryma whipplei. The patient recovered after intravenous ceftriaxone and oral trimethoprim-sulfamethoxazole. The final diagnosis was lung T. whipplei infection and long COVID-19.

Conclusion
This is the first case report of Tropheryma whipplei infection in the lung of a patient with long COVID-19. T. whipplei should be considered as a potential pathogen for diffuse lung infiltration in the post-COVID-19 era.
