A Novel Human Microbe-Disease Association Prediction Method Based on the Bidirectional Weighted Network

Conclusion Human microbiome is normal flora for humans, which has been proved to be of symbiotic relationship with humans and harmless to humans. If the microbes that breed in the human body become “unhealthy,” it will definitely affect the host's physical condition. People are continuing to explore the pathologic relationship between microorganisms and the human body through high-throughput sequencing technologies and analysis systems. However, it is a pity that their pathogenesis cannot be fully understood as yet. Considering that relying only on conventional experimental methods is time-consuming and laborious, in this article, we proposed a novel prediction model called BWNMHMDA to accelerate the process of inferring potential microbe-disease associations, in which, the core idea is to construct a weighted bidirectional microbe-disease association network and then convert it into a matrix for correlation probability calculation. While constructing the prediction model BWNMHMDA, we first downloaded known microbe-disease associations from the HDMDA database, and then, based on these downloaded associations, we constructed a heterogeneous network through adopting the Gaussian interaction profile kernel similarity to calculate the weights of nodes in the heterogeneous network. Moreover, based on the heterogeneous network, we further constructed a weighted bidirectional network by standardizing the weights of edges in the heterogeneous network and introduc...

ConclusionOverall, these guidelines provide consistent recommendations on who should receive breast reconstruction education, who is a candidate for postmastectomy breast reconstruction, and the appropriate timing of reconstruction and extent of mastectomy. Future updates from all should focus on expanding to include alloplastic and autologous forms of reconstruction and should include a broad scope of relevant questions.

Hello all, I have a question I'm not sure about the answer or where to post on the forum. Patient is going to have knee replacement and has penicillin allergy, although he is stable on cephalexin. What would be the best antibiotic to use peri-operatively? Choice of antibiotics: cefazolin, vancomycin, clindamycin. I was thinking cefazolin because it's a 1st gen like cephalexin, but a friend argued for vancomycin. What do you guys think?

This study, therefore, aims to investigate the effects of generalised trust and happiness on all-cause and cause-specific mortality. The distinction between different causes of death (i.e. cardiovascular vs. cancer-related mortality) allowed us to assess if psychosocial mechanisms could account for associations between generalised trust, happiness and mortality. The study sample was derived from US General Social Survey data from 1978 to 2010 (response rates ranged from 70 to 82 per cent), and combined with death records from the National Death Index. The analytical sample comprised 23,933 individuals with 5382 validated d...

Authors: Lin WC, Tsai JP, Lai YH, Lin YL, Kuo CH, Wang CH, Hsu BG Abstract Osteoprotegerin (OPG) is a potential biomarker of cardiovascular disease complications and severity. Peripheral arterial disease (PAD) is associated with an increased risk of death in patients on peritoneal dialysis (PD). Therefore, this study aimed to evaluate the relationship between serum OPG levels and PAD by measuring the ankle-brachial index (ABI) of patients on PD. A commercial enzyme-linked immunosorbent assay kit was used to measure OPG values. Left or right ABI values of

The relateddata were derived from The Cancer Genome Atlas (TCGA), and then, analyzed by Weightedgene co-expression network analysis (WGCNA). The correlation between each module andthe clinical traits were analyzed by Pearson's correlation analysis. Pathway analysis wasconducted to reveal potential mechanisms. Hub genes within each module were screenedby intra-module analysis, and vis...

This study has important implications for the future investigations of prevention of periprosthetic infection. The nomogram model identifies high-risk patients for whom attached prophylaxis measures are required. Future studies regarding reduction of incidence of periprosthetic infection should pay close attention to these high-risk patients.Level of evidenceIV, retrospective, cohort study.

We report a unique case of a 60-year-old woman developing endometrial cancer in a uterine deposit 18 years after she had undergone laparoscopic subtotal hysterectomy with morcellation for benign pathology. She had used unopposed estrogen as menopausal hormone therapy. She presented with a pelvic mass that was causing pressure symptoms. On imaging, the mass had an enhancing vascular nodular component and appeared to abut normal ovaries and the residual cervix. She proceeded to laparotomy, where a 12 cm pelvic mass was found morbidly adherent to the bladder anteriorly and to the cervical stump. The pelvic mass was excise...
