Abstract
Background
The aim was to assess the association between levels of advanced glycation endproducts (AGEs) in the gingival crevicular fluid (GCF) and periodontal parameters among cigarette-smokers and waterpipe-users.

Methods
Self-reported cigarette-smokers; waterpipe-users and never-smokers were included. Demographic data was recorded using a questionnaire. Periodontal parameters (plaque index [PI], gingival index [GI], clinical attachment loss [AL], probing depth [PD], and marginal bone loss [MBL]) were assessed in all groups. The GCF samples were collected using standard techniques and assessed for AGEs levels using enzyme-linked immunosorbent assay. Sample-size estimation was done and group-comparisons were done. Correlation between levels of GCF AGEs levels and periodontal parameters was assessed using a logistic regression model. Level of significance was set at P < 0.01.

Results
Eighty-two individuals (28 cigarette-smokers, 28 waterpipe-users and 26 never-smokers) were included. There was no difference in mean ages of all patients. Cigarette-smokers had a smoking history of 5.1 ± 0.2 pack years and waterpipe-users were using waterpipe for 4.4 ± 0.6 years. There was no statistically significant difference in PI, GI, clinical AL, PD and MBL in all groups. Levels of AGEs were significantly higher among cigarette-smokers (P < 0.001) and waterpipe-users (P < 0.001) than never-smokers. There was no significant correlation between levels of GCF AGEs levels and periodontal parameters in all groups.

Conclusion
Clinical periodontal status of individuals with a short history of cigarette-smoking and waterpipe-usage may appear similar to never-smokers. On a molecular level, cigarette-smoking and waterpipe-users express raised levels of AGEs than never-smokers that sirens about the ongoing yet latent periodontal inflammatory process.

Abstract
Objective
We aimed to evaluate the hysteroscopic management of first-trimester pregnancy loss compared to surgical evacuation either blind or under ultrasonographic guidance‎.

Methods
This clinical trial included ‎315 women with first-trimester pregnancy loss, divided equally into three groups. Group 1 underwent traditional blind surgical evacuation, group 2 underwent ultrasound-guided evacuation, and group 3 underwent hysteroscopic management. All women were assessed for retained products, surgical complications, the need for further management, and pregnancy occurrence after evacuation within 2 years of follow up.

Results
The rate of presence of conception remnants and the need for further ‎treatment was significantly higher in group 1 compared to groups 2 and 3 (4.8% vs. 0% vs. 0%, P = 0.012). The conception rate within 2 years was significantly lower in group 1 compared to groups 2 and 3 (57.4% vs. 73.2% vs. 82.7%, P = 0.002), and the duration needed to conceive was significantly prolonged in group 1 compared to groups 2 and 3 (9.8 vs. 8.3 vs. 6.9 months, P < 0.001). Interestingly, women who underwent hysteroscopic management needed a significantly shorter time to conceive than those who underwent ultrasound-guided evacuation‎ (6.9 vs. 8.3 months, P = 0.006).

Conclusions
Hysteroscopic management of first-trimester pregnancy loss was superior to ultrasound-guided surgical evacuation regarding the time interval to conceive. Both techniques were superior to the blind evacuation technique regarding removal of the whole conception remnants, need for further treatment and fertility outcomes.

Authors: Konje Eveline T. , Msuya Itikija E. , Matovelo Dismas , Basinda Namanya , Dewey Deborah 
Published: May 2022

Abstract
Background
Most (94%) of global maternal deaths occur in low- and middle-income countries due to preventable causes. Maternal health care remains a key pillar in improving survival. Antenatal care (ANC) guidelines recommend that pregnant women should be provided with information about postnatal care in the third trimester. However, the utilization of postnatal care services is limited in developing countries including Tanzania. The aim of this study was to investigate the practice of health care workers in providing information on postnatal care to pregnant women during antenatal care visits.

Methods
A cross sectional study was conducted among health care workers from 27 health facilities that offer reproductive and child health services in Busega district Northwest Tanzania. A simulated client approach was utilized to observe quality of practice among health care workers with minimal reporting bias (i.e., the approach allows observing participants at their routine practices without pretending). Selected pregnant women who were trained to be simulated clients from the community within facility catchment area attended antenatal care sessions and observed 81 of 103 health care workers. Data analyses were carried out using STATA 13.

Results
Only 38.73% (95% CI; 28.18–49.49%) of health care workers were observed discussing subtopics related to postnatal care during the ANC visit. Few health care workers (19.35%), covered all eight subtopics recommended in the ANC guidelines. Postnatal danger signs (33.33%) and exclusive breast feeding (33.33%) were mostly discussed subtopics by health care workers. Being a doctor/nurse/clinical officer is associated by provision of postnatal education compared to medical attendant, aOR = 3.65 (95% CI; 1.21–12.14).

Conclusion
The provision of postnatal education during ANC visits by health care workers in this district was limited. This situation could contribute to the low utilization of postnatal care services. Health care workers need to be reminded on the importance of delivering postnatal education to pregnant women attending ANC clinic visits. On job training can be used to empower health care workers of different cadres to deliver postnatal health education during ANC visits. These efforts could increase women’s utilization of postnatal care and improve outcomes for mothers and newborns.

Published: May 2022

AbstractThe isotopic fractionation factor and element partition coefficient can be calculated only after the geometric optimization of the molecular clusters is completed. Optimization directly affects the accuracy of some parameters, such as the average bond length, molecular volume, harmonic vibrational frequency, and other thermodynamic parameters. Here, we used the improved volume variable cluster model (VVCM) method to optimize the molecular clusters of a typical oxide, quartz. We documented the average bond length and relative volume change. Finally, we extracted the harmonic vibrational frequencies and calculated the equilibrium fractionation factor of the silicon and oxygen isotopes. Given its performance in geometrical optimization and isotope fractionation factor calculation, we further applied the improved VVCM method to calculate isotope equilibrium fractionation factors of Cd and Zn between the hydroxide (Zn–Al layered double hydroxide), carbonate (cadmium-containing calcite) and their aqueous solutions under superficial conditions. We summarized a detailed procedure and used it to re-evaluate published theoretical results for cadmium-containing hydroxyapatite, emphasizing the relative volume change for all clusters and confirming the optimal point charge arrangement (PCA). The results showed that the average bond length and isotope fractionation factor are consistent with those published in previous studies, and the relative volume changes are considerably lower than the results calculated using the periodic boundary method. Specifically, the average Si–O bond length of quartz was 1.63 Å, and the relative volume change of quartz centered on silicon atoms was − 0.39%. The average Zn–O bond length in the Zn–Al-layered double hydroxide was 2.10 Å, with a relative volume change of 1.96%. Cadmium-containing calcite had an average Cd–O bond length of 2.28 Å, with a relative volume change of 0.45%. At 298 K, the equilibrium fractionation factors between quartz, Zn–Al-layered double hydroxide, cadmium-containing calcite, and their corresponding aqueous solutions were $$\Delta ^{30/28} {\text{Si}}_{{{\text{Qtz-H}}_{4} {\text{SiO}}_{4} }} = 2.20{\permil} $$

Authors: Kim Si Hyoung , Cho Yun Kyung , Kim Ye-Jee , Jung Chang Hee , Lee Woo Je , Park Joong-Yeol , Huh Ji Hye , Kang Jun Goo , Lee Seong Jin , Ihm Sung-Hee 
Published: May 2022

Abstract
Background
The atherogenic index of plasma (AIP) is composed of triglycerides and high-density lipoprotein cholesterol and is a novel marker for assessing the risk of atherogenicity and cardiometabolic health. An association between AIP and greater frequency of major adverse cardiovascular events (MACEs) in patients with type 2 diabetes mellitus and high cardiovascular (CV) disease risk has been reported. However, only few studies have examined the correlation between AIP and CV risk in general populations. We thus aimed to evaluate the relationship between AIP and CV diseases using a large-scale population dataset from the Korean National Health Insurance Service-National Health Screening Cohort (NHIS-HEALS).

Methods
A total of 514,866 participants were enrolled from the NHIS-HEALS and classified according to the AIP quartiles. We performed univariate and multivariate Cox proportional hazards regression analyses to determine the association between AIP and MACEs, CV events, and CV mortality.

Results
During follow-up, we documented 12,133, 11,055, and 1942 cases of MACEs, CV events, and CV mortality, respectively. The multivariate-adjusted hazard ratios [HRs; 95% confidence interval (CI)] for MACEs gradually and significantly increased with the AIP quartiles [1.113 (1.054–1.175) in Q2, 1.175 (1.113–1.240) in Q3, and 1.278 (1.209–1.350) in Q4], following an adjustment for the conventional CV risk factors, including age, sex, body mass index, smoking, alcohol drinking, physical activities, household income, fasting glucose, systolic blood pressure, low-density lipoprotein cholesterol, and estimated glomerular filtration rate. In subgroup analyses, the association of AIP with MACEs and CV events was particularly outstanding in patients with diabetes.

Conclusions
AIP was significantly associated with CV risks after adjusting for the traditional risk factors. Therefore, it may be used as an effective mass screening method to identify patients at a high risk of CV events.
LINC01806 mediated by STAT1 promotes cell proliferation, migration, invasion, and stemness in non-small cell lung cancer through Notch signaling by miR-4428/NOTCH2 axis
Authors: Huang Shangxiao , Liang Shixiong , Huang Jianfeng , Luo Penghui , Mo Dunchang , Wang Hanlei 
Published: May 2022

Abstract
Background
Non-small cell lung cancer (NSCLC), the most primary lung cancer subtype, threatens human health globally. Long non-coding RNAs (lncRNAs) have been uncovered to affect multiple cancers progression. Nevertheless, the specific function of long intergenic non-protein coding RNA 1806 (LINC01806) in NSCLC remains elusive.

Methods
RT-qPCR and western blot were involved in this study. The influence of LINC01806 on NSCLC was assessed by in vitro and in vivo assays. Via ChIP, RNA pull down, RIP, and luciferase reporter assays, the in-depth cellular mechanisms of LINC01806 in NSCLC were explored.

Results
LINC01806 expression was high in NSCLC cell lines. Functionally, LINC01806 knockdown impeded cell proliferation, migration, invasion, and stemness, along with tumor growth. As for its mechanism, signal transducer and activator of transcription 1 (STAT1) activated LINC01806 transcription in NSCLC. Furthermore, LINC01806 sequestered microRNA-4428 (miR-4428) to enhance notch receptor 2 (NOTCH2) expression, thus activating Notch signaling pathway. Finally, in vitro and in vivo assays jointly validated that LINC01806 exerted its function in NSCLC development via miR-4428/NOTCH2 pathway.

Conclusion
LINC01806 enhanced NOTCH2 expression to stimulate Notch signaling via sponging miR-4428, thereby facilitating NSCLC progression, which provided a novel mechanism for NSCLC therapeutic approaches.

AbstractCancer can be induced by a variety of possible causes, including tumor suppressor gene failure and proto-oncogene hyperactivation. Tumor-associated extrachromosomal circular DNA has been proposed to endanger human health and speed up the progression of cancer. The amplification of ecDNA has raised the oncogene copy number in numerous malignancies according to whole-genome sequencing on distinct cancer types. The unusual structure and function of ecDNA, and its potential role in understanding current cancer genome maps, make it a hotspot to study tumor pathogenesis and evolution. The discovery of the basic mechanisms of ecDNA in the emergence and growth of malignancies could lead researchers to develop new cancer therapies. Despite recent progress, different aspects of ecDNA require more investigation. We focused on the features, and analyzed the bio-genesis, and origin of ecDNA in this review, as well as its functions in neuroblastoma and glioma cancers.

Published: May 2022

Abstract
Background
Machine learning, especially deep learning, is becoming more and more relevant in research and development in the medical domain. For all the supervised deep learning applications, data is the most critical factor in securing successful implementation and sustaining the progress of the machine learning model. Especially gastroenterological data, which often involves endoscopic videos, are cumbersome to annotate. Domain experts are needed to interpret and annotate the videos. To support those domain experts, we generated a framework. With this framework, instead of annotating every frame in the video sequence, experts are just performing key annotations at the beginning and the end of sequences with pathologies, e.g., visible polyps. Subsequently, non-expert annotators supported by machine learning add the missing annotations for the frames in-between.

Methods
In our framework, an expert reviews the video and annotates a few video frames to verify the object’s annotations for the non-expert. In a second step, a non-expert has visual confirmation of the given object and can annotate all following and preceding frames with AI assistance. After the expert has finished, relevant frames will be selected and passed on to an AI model. This information allows the AI model to detect and mark the desired object on all following and preceding frames with an annotation. Therefore, the non-expert can adjust and modify the AI predictions and export the results, which can then be used to train the AI model.

Results
Using this framework, we were able to reduce workload of domain experts on average by a factor of 20 on our data. This is primarily due to the structure of the framework, which is designed to minimize the workload of the domain expert. Pairing this framework with a state-of-the-art semi-automated AI model enhances the annotation speed further. Through a prospective study with 10 participants, we show that semi-automated annotation using our tool doubles the annotation speed of non-expert annotators compared to a well-known state-of-the-art annotation tool.

Conclusion
In summary, we introduce a framework for fast expert annotation for gastroenterologists, which reduces the workload of the domain expert considerably while maintaining a very high annotation quality. The framework incorporates a semi-automated annotation system utilizing trained object detection models. The software and framework are open-source.

AbstractBackgroundLow-energy diets (LEDs) comprise commercially formulated food products that provide between 800 and 1200 kcal/day (3.3–5 MJ/day) to aid body weight loss. Recent small-scale studies suggest that LEDs are associated with marked changes in the gut microbiota that may modify the effect of the LED on host metabolism and weight loss. We investigated how the gut microbiota changed during 8 weeks of total meal replacement LED and determined their associations with host response in a sub-analysis of 211 overweight adults with pre-diabetes participating in the large multicentre PREVIEW (PREVention of diabetes through lifestyle intervention and population studies In Europe and around the World) clinical trial.MethodsMicrobial community composition was analysed by Illumina sequencing of the hypervariable V3-V4 regions of the 16S ribosomal RNA (rRNA) gene. Butyrate production capacity was estimated by qPCR targeting the butyryl-CoA:acetate CoA-transferase gene. Bioinformatics and statistical analyses, such as comparison of alpha and beta diversity measures, correlative and differential abundances analysis, were undertaken on the 16S rRNA gene sequences of 211 paired (pre- and post-LED) samples as well as their integration with the clinical, biomedical and dietary datasets for predictive modelling.ResultsThe overall composition of the gut microbiota changed markedly and consistently from pre- to post-LED (P= 0.001), along with increased richness and diversity (bothP< 0.001). Following the intervention, the relative abundance of several genera previously associated with metabolic improvements (e.g.,AkkermansiaandChristensenellaceaeR-7 group) was significantly increased (P< 0.001), while flagellatedPseudobutyrivibrio, acetogenicBlautiaandBifidobacteriumspp. were decreased (allP< 0.001). Butyrate production capacity was reduced (P< 0.001). The changes in microbiota composition and predicted functions were significantly associated with body weight loss (P< 0.05). Baseline gut microbiota features were able to explain ~25% of variation in total body fat change (post–pre-LED).ConclusionsThe gut microbiota and individual taxa were significantly influenced by the LED intervention and correlated with changes in total body fat and body weight in individuals with overweight and pre-diabetes. Despite inter-individual variation, the baseline gut microbiota was a strong predictor of total body fat change during the energy restriction period.Trial registrationThe PREVIEW trial was prospectively registered at ClinicalTrials.gov (NCT01777893) on January 29, 2013.
Squamous cell carcinoma of verrucous type in the setting of prior pyoderma gangrenosum: a case report
Authors: Morrison Amy , Waters-Hollingsworth Carlene , Gamboa G. Mabel 
Published: May 2022

Abstract
Introduction
Pyoderma gangrenosum and cutaneous squamous cell carcinoma are two conditions well reported in the literature and may exist concurrently in the same patient. In fact, there have been reports of misdiagnosis of one for the other. The two conditions occurring in the same location, however, has not yet been reported.

Case description
We report the case of a 57-year-old Caucasian male with history of pyoderma gangrenosum of the right lateral tibial area who developed squamous cell carcinoma of verrucous type at the same site. Excisional surgery was considered to treat this patient, but he was ultimately managed with radiation therapy to the affected area due to the size of the lesion and the risk of triggering proliferation of the pyoderma gangrenosum.

Conclusions
We hope that this case report will add to the literature of both conditions, show a unique presentation of both conditions, and emphasize the inclusion of both pyoderma gangrenosum and squamous cell carcinoma when developing a differential diagnosis of a chronic, nonhealing wound.

AbstractThe structure and types of rumen microbes are closely related to host health. This study aimed to evaluate the effect of Broussonetia papyrifera silage (BPS) gradually replacing the whole crop maize silage (WCMS) on total tract digestibility, rumen fermentation parameters, serum biochemical indicators, and rumen microbes of Holstein heifers. The diet treatment consisted of four proportions of BPS (0%, 25%, 50% and 75%) as substitute for WCMS (designated as T0, T25, T50 and T75, respectively). Twenty heifers (body weight = 245 ± 24 kg) were randomly divided into four groups of five heifers, and randomly received one diet. The feeding adaption period was 7 days, and the experiment period was 30 days. Our findings suggested that the digestibility of neutral detergent fiber and crude protein increased linearly with the increased in BPS (P < 0.05). The concentrations of total protein and albumin increased quadratically with the increased in BPS (P < 0.05). The 16s high-throughput sequencing showed that feeding BPS did not change the diversity and structure of the rumen microbes of heifers. However, the relative abundances of Tenericutes and SR1–Absconditabacteria increased linearly with the increased in BPS (P < 0.05). The Weighted Correlation Network Analysis results suggested that ALT concentration was positively correlated with the abundance of Prevotella-1 (r = 0.73; P = 0.007). In general, Holstein heifers fed with BPS did not change the diversity and uniformity of rumen microbes, and enhanced the body protein metabolism.
