    In conclusion, T. canis larval migration activated the MMPs and caused pulmonary pathogenesis.

    These phenomena subsequently induced the activities of MMPs in parallel with the pathological changes in early stage pulmonary inflammation. In conclusion, T. canis larval migration activated the MMPs and caused pulmonary pathogenesis.

    Respiratory viruses (RVs) are among the most common pathogens for both upper and lower respiratory tract infections (RTIs). However, the viral epidemiology of RV-associated RTIs in adults has long been under-recognized. Through a sensitive molecular assay, it would be possible to have a better understanding of the epidemiology of RV-associated RTIs.

    Respiratory tract (RT) specimens from adults hospitalized due to RTIs were tested for RVs, using the multiplex PCR-based Luminex xTAG® Respiratory Viral Panel assay. A total of nineteen RVs, including influenza viruses and non-influenza respiratory viruses (NIRVs) were detected. Positive rates were compared using a chi-square test.

    A total of 2292 samples from adult patients hospitalized with RTIs were screened for RVs. The overall positive rate was 22%, with 17.8% samples positive for at least one NIRV. NIRVs had a higher positive rate in non-winter seasons. As many as 12.7% (46/363) of the samples collected through broncho-alveolar lavage and 20.5% (176/859) of the samples collected in ICUs were positive for RVs. Distribution of corona virus (CoV), human metapneumovirus (hMPV) and parainfluenza virus (PIV) demonstrated seasonal variation. Also, temperature was associated with the positive rates of specific viruses, including CoV, respiratory syncytial virus (RSV), hMPV and PIV.

    Respiratory viruses, notably NIRVs, were frequently detected in adults hospitalized with RTIs. selleck chemical Several RVs were detected with distinctive seasonal variations. A substantial number of RVs were identified in lower RT specimens or from patients admitted to ICU, highlighting their important role in causing severe respiratory infection.

    Group B streptococcus (GBS) is a leading cause of serious infection in infants. Understanding its regional molecular epidemiology is helpful for regulating efficient prevention practice.

    A retrospective study was conducted to collected data from infants and pregnant women with culture-proven GBS disease in the largest women and children’s medical center in Shanxi between January 2017 and September 2019. All GBS isolates were analyzed by multi-locus sequence typing (MLST) as well as distribution of pilus island (PI) genes.

    A total of 54 GBS isolates were obtained from 36 (66.7%) pregnant women and 18 (33.3%) infants with invasive disease. Among invasive GBS strains, the most common sequence type was ST10 (72.2%, P<0.05), followed by ST23 and ST19. The ST10 strain was also the leading sequence type in colonizing pregnant women (44.4%, P<0.05). All of the isolates carried at least one pilus island. The most frequently detected pilus island was PI-1+PI-2a (85.2%, P<0.05), followed in turn by PI-2a and PI-2b.

    Our study demonstrates that one hypervirulent clone, sequence type 10, accounts for a large proportion of invasive GBS disease in infants and colonizing pregnant women, and the PI-1+PI-2a sub-lineages should be noted in infant infections.

    Clostridium difficile infections (CDIs) cause significant mortality and morbidity. Critically ill patients are susceptible to CDIs and tend to have severe CDIs, and their clinical presentations are not merely diarrhea.

    From September 2017 to March 2018, the adults with CDIs in the ICUs were included. Fecal specimens with positive results of glutamate dehydrogenase assay were cultured for C. difficile, and toxinotyping and ribotyping for available C. difficile isolates were done. The CDI cases were categorized into the diarrheal group and ileus group. Difficult-to-treat cases with the presentations of life-threatening complications (bowel perforation or bacteremia), toxic megacolon, and refractory diarrhea, were analyzed.

    Totally 23 cases, including 6 cases of ileus and 17 of diarrhea, were included. Overall, the incidence of CDI in the ICUs was 10.7 cases per 10,000 patient-days. The ileus group tended to have more severe presentation, shorter ICU stay, higher ICU mortality, and receive initial intravenous metronidazole therapy. Severe and fulminant CDIs accounted for 65.2% (15 cases). The ICU mortality rate was 39.1%, but only one death was directly related to CDI (4.3%). Of nine (39.1%) difficult-to-treat cases, there was only one isolate of RT611 with tcdC deletion and cdtA/cdtB from a case with toxic megacolon. No hypervirulent isolates of RT027 or 078 were detected.

    Severe CDIs in the ICU were not rare. Clinicians should be aware of abdominal symptoms and signs other than diarrhea, such as ileus, to make timely diagnosis and management of CDI.

Oral semaglutide is the first oral GLP-1RA. In clinical trials, oral semaglutide 14 mg reduced mean HbA1c by approximately 1.1-1.5% and reduced body weight by up to 5 kg. These changes were significantly greater compared with empagliflozin, sitagliptin and liraglutide (p less then 0.05 for estimated treatment differences at 52 weeks in patients on treatment without rescue medication use). The most common side effects were gastrointestinal, mainly mild-to-moderate and transient nausea. Oral semaglutide may change the paradigm of T2D treatment in primary care.
