Abstract
Objective
To explore the relationship of MRI morphology of primary rectal cancer with extramural vascular invasion (EMVI), metastasis and local recurrence.

Materials and methods
This retrospective study included 153 patients with rectal cancer. Imaging factors and histopathological index including nodular projection (NP), cord sign (CS) at primary tumor margin, irregular nodules (IN) of mesorectum, MRI-detected peritoneal reflection invasion (PRI), range of rectal wall invasion (RRWI), patterns and length of tumor growth, maximal extramural depth (EMD), histologically confirmed local node involvement (hLN), MRI T stage, MRI N stage, MRI-detected extramural vascular invasion (mEMVI) and histologically confirmed extramural vascular invasion (hEMVI) were evaluated. Determining the relationship between imaging factors and hEMVI, synchronous metastasis and local recurrence by univariate analysis and multivariable logistic regression, and a nomogram validated internally via Bootstrap self-sampling was constructed based on the latter.

Results
Thirty-eight cases of hEMVI, fourteen cases of synchronous metastasis and ten cases of local recurrence were observed among 52 NP cases. There were 50 cases of mEMVI with moderate consistency with hEMVI (Kappa = 0.614). NP, CS, EMD and mEMVI showed statistically significant differences in the negative and positive groups of hEMVI, synchronous metastasis, and local recurrence. Compared to patients with local mass growth, the rectal tumor with circular infiltration had been found to be at higher risk of synchronous metastasis and local recurrence (P < 0.05). NP and IN remained as significant predictors for hEMVI, and mEMVI was a predictor for synchronous metastasis, while PRI and mEMVI were predictors for local recurrences. The nomogram for predicting hEMVI demonstrated a C-index of 0.868, sensitivity of 86.0%, specificity of 79.6%, and accuracy of 81.7%.

Conclusion
NP, CS, IN, large EMD, mEMVI, and circular infiltration are significantly associated with several adverse prognostic indicators. The nomogram based on NP has good predictive performance for preoperative EMVI. mEMVI is a risk factor for synchronous metastasis. PRI and mEMVI are risk factors for local recurrence.

Abstract
Background
Functional dyspepsia (FD) as a type of disorders of brain-gut interaction (DBGI), patient self-reporting of its symptoms becomes an important component of clinical outcome assessment. We performed a systematic review using Consensus Based Standards for the Selection of Health Measurement Instruments (COSMIN) guidelines to identify the best available patient-reported outcome measure (PROM) of FD.

Methods
The study was conducted according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA). We searched four databases with no date limit, looking for previously confirmed PROMs for evaluating FD symptoms. An overall rating was then assigned based upon COSMIN guidelines, and the Grading of Recommendations Assessment, Development, and Evaluation (GRADE) approach was used to assess the level of evidence for psychometric properties of included PROMs.

Results
Thirty articles covering outcome indicators of 24 patient reports were included. The Leuven Postprandial Distress Scale (LPDS) showed adequate content validity and moderate quality evidence of adequate internal consistency to generate an A recommendation.

Conclusion
LPDS is currently the most recommended PROM for patient self-reported FD symptoms. However, it fails to assess two important areas of cross-cultural validity/ measurement invariance and measurement error. Future research can be continuously improved on this basis.

Published: September 2023

Abstract
Background
There are few studies on acute-on-chronic liver failure (ACLF) in patients with recompensated cirrhosis. This study was aimed to investigate the clinical features of ACLF patients with recompensated cirrhosis.

Methods
A total of 461 ACLF patients were enrolled and divided into three groups: compensated, recompensated, and decompensated cirrhosis with ACLF. The baseline clinical data and 1-year survival rates were compared among the three groups.

Results
Compared with the decompensated group, in the recompensated group, the levels of hemoglobin, albumin, and serum sodium were significantly higher and the white blood cell count, international normalized ratio, and incidence of respiratory failure were significantly lower; there were no evident differences in other organ failures. The proportion of patients with ACLF grade 3 and 1-year survival rates significantly differed between the two groups. Conversely, compared with the compensated group, in the recompensated group, the platelet and total bilirubin levels were significantly lower and the proportion of patients with ACLF grade 1 was significantly higher. However, other clinical indicators or 1-year survival rates did not significantly differ between the two groups.

Conclusions
Compared with patients who developed ACLF with decompensated cirrhosis, those who developed ACLF with recompensated cirrhosis had a less severe condition, lower incidence of respiratory failure, and better 1-year prognosis. However, the baseline clinical features and prognosis were similar between ACLF patients with recompensated and compensated cirrhosis.

Dialister pneumosintes and aortic graft infection – a case report
Authors: Patel Rachel , Chong Debra S. T. , Guy Alison J. , Kennedy Matthew 
Published: September 2023

Abstract
Background
Dialister pneumosintes is an anaerobic, Gram negative bacillus, found in the human oral cavity and associated with periodontitis. It has also been isolated from gastric mucosa and stool samples. Recent case reports implicate D. pneumosintes in local infection such as dental root canals, sinusitis, Lemierres syndrome and brain abscesses, as well as distal infections of the liver and lung through haematogenous spread.

Case presentation
We present a novel case of aortic graft infection and aortoenteric fistula (AEF) in a 75 year old Caucasian male, associated with D. pneumosintes bacteraemia. Microbiological evaluation of septic emboli in the lower limbs revealed other gastrointestinal flora. This suggests either AEF leading to graft infection and subsequent distal emboli and bacteraemia, or a dental origin of infection which seeded to the graft, resulting in AEF and systemic infection. To our knowledge this is the first report of D. pneumosintes associated aortic graft infection. The patient underwent surgical explantation, oversew of the aorta and placement of extra-anatomical bypass graft in conjunction with antimicrobial therapy, making a good recovery with discharge home after a 35-day hospital admission.

Conclusion
We report a case of Dialister pneumosintes bacteraemia associated with aortic graft infection. To our knowledge, vascular graft-associated infection with D. pneumosintes has not been reported before.

Published: September 2023

AbstractBackgroundTransgender (TG) people are key drivers for sexually transmitted infections (STIs) all over the world. There is substantial evidence that STIs are associated with an increased likelihood of risky sexual behavior however little is known about the prevalence of STIs (HIV, HBV, HCV, and Syphilis) among HIV infected transgender population in Pakistan.MethodsThe current study investigated the seroprevalence of four STIs and associated socio-demographic risk factors among TGs of Punjab, Pakistan from July 2019 to June 2021. The samples were tested serologically and final confirmation was done through PCR for HIV, HBV, and HCV.ResultsA total of 1,562 transgenders cross-sectional descriptive records of the Punjab AIDS Control Program (PACP) were reviewed during the period from July 2019 to June 2021. The serological results evidenced that 533 (34.1%) had one pathogen, 309 (19.8%) had two or more (multiple) infections. The most predominant mono-infection among the transgender population was Syphilis 324 (20.7%) followed by HCV 114 (7.3%), HIV 69 (4.4%), and HBV 26 (1.7%). The highest proportions of Infections were found in TG residing in urban areas (68.6%) as compared to rural areas (31.4%). The seropositivity of all STIs was predominantly increased in Sex worker TGs i-e 55%, 46.5%, 38.5%, and 41.8% in HIV, HBV, HCV, and Syphilis respectively. Among 280 HIV-infected Transgender, 177 (63.2%) had Syphilis co-infections. While 87 (31%) and 47 (16.8%) HIV-infected individuals had HC and HBV co-infection respectively.ConclusionTransgender is neglected population group in society. All STIs were predominantly common among sex worker transgenders, Illiterate educational groups, and TGs residing in urban areas. There is a need to spread awareness about STIs, preventive strategies, and facilitation to health care programs in this high-risk population group.

Published: September 2023

Abstract
Background
The gastrointestinal tract contains a massive microbiota, and targeting the gut could be a potential intervention for sepsis. However, the interaction between sepsis and the intestinal microbiota is defined as an “incompletely understood bidirectional relationship”.

Methods
This retrospective observational cohort study investigated the fecal microbiota of sepsis patients admitted to the Department of Critical Care Medicine of the Central Hospital of Wuhan, China, from May 2019 to January 2020. 14 septic patients were divided into the non-severe group and the severe group according to the Acute Physiology and Chronic Health Evaluation II (APACHE II) score. Herein, fecal samples were serially collected on admission, the third, fourth, and fifth days, and ICU discharge. The fecal microbiota was analyzed by 16S rRNA gene sequencing and its correlation with clinical parameters was evaluated.

Results
Bacteroidetes, Firmicutes, and Proteobacteria were dominant phyla at ICU admission, and fecal biodiversity was not significantly different between the non-severe group (APACHE II < 15) and the severe group (APACHE II > 15). However, the diversity of the gut microbiota was significantly lower at ICU discharge than that at ICU admission with the extension of treatment time. Further significant difference flora analysis (LEfSe) showed that the genera Veillonella and Ruminococcus were the most discriminant biomarkers at ICU admission in non-severe and severe patients, respectively, while Enterococcus was the most discriminant biomarker at ICU discharge in all septic patients. Of note, liver function tests, including ALT, AST, TBIL, and DBIL correlated with the prevalence of various bacterial genera.

Conclusions
The diversity of the gut microbiota in patients with sepsis decreases dramatically during ICU stay, and there are distinct dynamic changes in gut microbiota among patients with different severity in sepsis.

Authors: Hornstrup Bodil G. , Hoffmann-Petersen Nikolai , Lauridsen Thomas Guldager , Bech Jesper N. 
Published: September 2023

Abstract
Purpose
Patients with treatment resistant hypertension (TRH) are at particular risk of cardiovascular disease. Life style modification, including sodium restriction, is an important part of the treatment of these patients. We aimed to analyse if self-performed dietary sodium restriction could be implemented in patients with TRH and to evaluate the effect of this intervention on blood pressure (BP). Moreover, we aimed to examine if mechanisms involving nitric oxide, body water content and BNP, renal function and handling of sodium were involved in the effect on nocturnal and 24-h BP. Also, measurement of erythrocyte sodium sensitivity was included as a possible predictor for the effect of sodium restriction on BP levels.

Patients and methods
TRH patients were included for this interventional four week study: two weeks on usual diet and two weeks on self-performed sodium restricted diet with supplementary handed out sodium-free bread. At the end of each period, 24-h BP and 24-h urine collections (sodium, potassium, ENaC) were performed, blood samples (BNP, NOx, salt blood test) were drawn, and bio impedance measurements were made.

Results
Fifteen patients, 11 males, with a mean age of 59 years were included. After sodium restriction, urinary sodium excretion decreased from 186 (70) to 91 [51] mmol/24-h, and all but one reduced sodium excretion. Nocturnal and 24-h systolic BP were significantly reduced (− 8 and − 10 mmHg, respectively, p < 0.05). NOx increased, BNP and extracellular water content decreased, all significantly. Change in NOx correlated to the change in 24-h systolic BP. BP response after sodium restriction was not related to sodium sensitivity examined by salt blood test.

Conclusion
Self-performed dietary sodium restriction was feasible in a population of patients with TRH, and BP was significantly reduced. Increased NOx synthesis may be involved in the BP lowering effect of sodium restriction.

Trial registration
The study was registered in Clinical trials with ID: NCT06022133.

Published: September 2023

Abstract
Background
Uterine arteriovenous malformation (UAVM) is a relatively rare but potentially life-threatening situations abnormal vascular connections between the uterine arterial and venous systems. Lack of recognized guidelines and clinic experience, there is a lot of clinic problems about diagnosis and treatment. By analyzing the clinical data of patients with pregnancy-related UAVM, we aim to confirm the safety of direct surgeries and the benefit of pretreatment (uterine artery embolization or medical therapy) before surgery, and to explore more optimal therapies for patients with pregnancy-related UAVM.

Methods
A total of 106 patients in Qilu Hospital of Shandong University from January 2011 to December 2021 diagnosed of pregnancy-related UAVM were involved in this study. Depending on whether preoperative intervention was performed, the patients were divided into direct surgery group and pretreatment group (uterine artery embolization or medical management). Clinical characteristics, operative related factors and prognosis were analyzed.

Results
The most common symptom of pregnancy-related UAVM was vaginal bleeding (82.5%), which could also be accompanied by abdominal pain. Pretreatments (uterine artery embolization or medical therapy) had no obvious benefit to the subsequent surgeries, but increased the hospital stay and hospital cost. Direct surgery group had satisfactory success rate and prognosis compared to pretreatment group.

Conclusion
For pregnancy-related UAVM, direct surgery has good effects and high safety with shorter hospital stays and less hospital cost. What is more, without uterine artery embolization and other medical therapy, patients could remain better fertility in future.

Published: September 2023

Abstract
Background
The aim of this study was to assess the effect of intensive nutrition education and counseling on hemoglobin level during pregnancy.

Methods and materials
The study was a one year two-arm parallel design cluster randomized controlled trial in East Shoa zone, Ethiopia. End-line data were collected from 163 intervention and 163 control group pregnant women. The intervention was a three consecutive trimester based counseling sessions using health belief model, weekly regular SMS sent on mobile phone containing core message and providing leaflet with food menu of Iron rich diet. The women in the control group received routine nutrition education from facilities. After adjusting for potential confounders, a linear mixed-effects model was used to assess the intervention effect.

Results
There was a significant change in both hemoglobin level and proportion of anemia in the intervention group. The mean hemoglobin level within intervention group before and after intervention was (12.08± 1.15, 12.53± 1.18) with p value of 0.01. The prevalence of anemia among intervention group declined from 14.7 % at the baseline to 9.2% after intervention. At the end of the trial, women in the intervention group had significantly better hemoglobin level than women in the control group (β = 0.50, p < 0.01).

Conclusion
The intervention was effective in improving the hemoglobin level and consumption of iron rich diet among pregnant women. Therefore, employing trimester based counseling by using HBM constructs and regular reminding messages have to be provided to pregnant women as part of the regular antenatal care service.

AbstractBackgroundPhysical activity has been utilized as an effective strategy to prevent gestational diabetes mellitus (GDM). However, most pregnant women with high risk for GDM did not achieve the recommended physical activity level. Furthermore, relevant physical activity protocols have varied without theory-guided and evidence-based tailored to pregnant women with high risk for GDM. This study aimed to develop and pilot test a theory-guided and evidence-based physical activity intervention protocol for pregnant women with high risk for GDM.MethodsThe study design was guided by the Medical Research Council Framework for Developing and Evaluating Complex Intervention (the MRC framework). The preliminary protocol for physical activity intervention was developed based on self-efficacy theory, research evidence identified from systematic reviews and clinic trials, stakeholder engagement, context, and economic considerations. The preliminary intervention protocol was validated through a content validity study by an expert panel of 10 experts. A single-blinded randomized controlled trial (RCT) was designed to test the feasibility and acceptability of the intervention.ResultsThe validity of the preliminary intervention protocol was excellent as consensus was achieved. The final 13 sessions of self-efficacy enhancing physical activity intervention protocol were developed, including knowledge education, exercise clinic visits and video, and group discussions with face-to-face and online blended sessions. In the feasibility study, 34 pregnant women with high risk for GDM were randomized for the intervention (n = 17) or the control group (n = 17). The recruitment and retention rates were 82.9% and 58.9%, respectively. Women in the intervention group had a lower incidence of GDM (26.7% vs. 36.5%) than the control group (P>0.05). All participants were satisfied with the intervention and agreed that the intervention was helpful.ConclusionsThe developed self-efficacy-enhancing physical activity intervention is a feasible and acceptable intervention for enhancing physical activity among pregnant women with high risk for GDM and is ready to be tested in a more extensive RCT study.Trial registrationThe study was registered on 4 February 2022 (ChiCTR2200056355) by the Chinese Clini Trial Registry (CHiCTR).

Published: September 2023

Abstract
Purpose
Thyroid cancer (TC) is one of the most common endocrine malignancies, and its morbidity continues to rise. N6-methyladenosine (m6A) RNA methylation, an epigenetic modification, is an important regulator of gene expression in TC. Therefore, it’s worth finding the characteristics and predictive value of the m6A RNA methylation regulators in thyroid cancer (TC).

Method
RNA-seq data of TC was downloaded from the Cancer Genome Atlas (TCGA) database to screen out the differential expressed regulators. The absolute contraction selection operator (Lasso) Cox regression was used to construct the risk model of m6A methylation regulators. The predictive value of the risk scoring model was evaluated by Kaplan Meier (K-M) analysis and receiver operating characteristic (ROC) curves. The underlying mechanism of m6A methylation regulators in TC was predicted by gene set enrichment analysis (GSEA). Further validation was performed by using immunohistochemistry (IHC) and q-PCR. The correlation between risk-related gene and immune infiltration was evaluated by Tumour Immune Estimation Resource (TIMER).

Results
IGF2BP2, YTHDF1 and YTHDF3 were screened out as strong independent prognostic factors of TC. Then a risk score model was established to further screen the predictors. Finally, according to the results of overall survival (OS) and clinical characteristics of TC, YTHDF3 was screened out as a potential predictor. Meanwhile, IHC and qPCR confirmed that YTHDF3 was expressed differential in TC. The expression of YTHDF3 was positively associated with the infiltration level of CD4+ T cells and macrophages. It was strongly correlated with a variety of immune markers in TC.

Conclusion
We confirmed that YTHDF3 can be used as a potential prognostic biomarker of TC. It not only plays a decisive role in the initiation and development of TC, but also provides a new perspective for understanding the modification of m6A RNA in TC.
