Knowledge of the prevalence and distribution of multidrug-resistant tuberculosis (MDR-TB) genotypes in northern Thailand is still limited. An accurate, rapid, and cost-effective diagnostic of MDR-TB is crucial to improve treatment and control of increased MDR-TB.
The molecular diagnostic assays named "RIF-RD" and "INH-RD" were designed to detect rifampicin (RIF) and isoniazid (INH) resistance based on real-time PCR and high-resolution melting curve analysis. BLU9931 Applying the ∆T
cutoff values, the RIF-RD and INH-RD were evaluated against the standard drug susceptibility testing (DST) using 107 and 103 clinical
(Mtb) isolates from northern Thailand. DNA sequence analysis of partial
, and
promoter of 73 Mtb isolates, which included 30 MDR-TB, was performed to elucidate the mutations involved with RIF and INH resistance.
When compared with the phenotypic DST, RIF-RD targeting
showed sensitivity, specificity, positive predictive value (PPV), and negative predictive value (NPV) of 83.9, 98.6, 96.9, a, emphasizing its usefulness as a low unit price assay for rapid screening of MDR-TB, with confirmation of INH resistance in low and middle-income countries. The MDR-TB genotypes provided will be beneficial for TB control and the development of drug-resistant TB diagnostic technology in the future.
This study aimed to evaluate the impacts of deep surgical site infections (dSSIs) regarding hospital readmissions, prolonged length of stay (LoS), and estimated costs.
We designed and applied a matched case-control observational study using the electronic health records at the University Medical Center Groningen in the Netherlands. We compared patients with dSSI and non-SSI, matched on the basis of having similar procedures. A prevailing topology of surgeries categorized as clean, clean-contaminated, contaminated, and dirty was applied.
Out of a total of 12,285 patients, 393 dSSI were identified as cases, and 2864 patients without SSIs were selected as controls. A total of 343 dSSI patients (87%) and 2307 (81%) controls required hospital readmissions. The median LoS was 7 days (P
-P
2.5-14.5) for dSSI patients and 5 days (P
-P
1-9) for controls (
-value <0.001). The estimated mean cost per hospital admission was €9,016 (SE±343) for dSSI patients and €5,409 (SE±120) for controls (p<0.001). Independent variables associated with dSSI were patient's age ≥65 years (OR 1.334; 95% CI 1.036-1.720), the use of prophylactic antibiotics (OR 0.424; 95% CI 0.344-0.537), and neoplasms (OR 2.050; 95% CI 1.473-2.854).
dSSI is associated with increased costs, prolonged LoS, and increased readmission rates. Elevated risks were seen for elderly patients and those with neoplasms. Additionally, a protective effect of prophylactic antibiotics was found.

In this review, we summarize the current evidence for the effects of gut microbes on the integrity of the cerebral blood-brain barrier (BBB), focusing on the pathogenic impact of gut microbiota disorders. Based on our description and summarization of the effects of the gut microbiota and its metabolites on the nervous, endocrine, and immune systems and related signaling pathways and the resulting destruction of the BBB, we suggest that regulating and supplementing the intestinal microbiota as well as targeting immune cells and inflammatory mediators are required to protect the BBB.
The aim of this study is to apply the advanced error-trend-seasonal (ETS) framework to forecast the prevalence and mortality series of COVID-19 in the USA, the UK, Russia, and India, and the predictive performance of the ETS framework was compared with the most frequently used autoregressive integrated moving average (ARIMA) model.
The prevalence and mortality data of COVID-19 in the USA, the UK, Russia, and India between 20 February 2020 and 15 May 2020 were extracted from the WHO website. Then, the data subsamples between 20 February 2020 and 3 May 2020 were treated as the training horizon, and the others were used as the testing horizon to construct the ARIMA models and the ETS models.
Based on the model evaluation criteria, the ARIMA (0,2,1) and ETS (M,MD,N), sparse coefficient ARIMA (0,2,(1,6)) and ETS (A,AD,M), ARIMA (1,1,1) and ETS (A,MD,A), together with ARIMA (2,2,1) and ETS (A,M,A) specifications were identified as the preferred ARIMA and ETS models for the prevalence data in the USA, the UK, d mortality in the USA, the UK, Russia, and India, and which provides a notable performance improvement over the most frequently used ARIMA model. Our findings can aid governments as a reference to prepare for and respond to the COVID-19 pandemic both in restricting the transmission of the disease and in lowering the disease-related deaths in the upcoming days.
In the present study, we aimed to describe the clinical features, diagnosis, treatment, and prognosis of spinal epidural abscess (SEA).
The complete clinical data of 11 SEA patients who were treated in our hospital system from January 2015 to June 2018 were retrospectively analyzed. Moreover, the clinical features, diagnosis, treatment, and prognosis of 642 SEA cases collected from the foreign literature from 2010 to 2019 were also investigated.
Among our 11 SEA patients, nine cases had purulent inflammation, two cases had tuberculosis, two cases had infection caused by
, one case had infection caused by
, one case had infection caused by
, five cases showed negative bacterial culture, and two cases had
. All 11 cases showed focal spinal pain, eight cases exhibited neurological deficits, and six cases experienced fever. Nine of the 11 cases involved the lumbosacral spine, one case involved the thoracic spine, and one case involved the cervical spine. Eight patients had a longer course of diseasetive culture results (

Urinary tract infection (UTI) is one of the most common bacterial infections in childhood, and the increasing rate of antibiotic resistance to the commonly prescribed antimicrobial agents against it has become a major concern. The aim of this study was to determine the antibiotic resistance and genotyping of bacteria isolated from urine cultures in patients referred to the Children's Medical Center, Tehran, Iran.
During the 1-year period, antimicrobial susceptibility profiles of strains isolated from patients with UTI were determined. Typing of the isolates causing nosocomial infections was performed by random amplified polymorphic DNA (RAPD) analysis, and the results were analyzed by Gelcompar II software.
In this study, 203 children (130 girls and 73 boys) were included. The patients' age ranged from 1 day to 16 years (IQR average=4 months to 4 years). The most frequent isolated organisms were
(118 isolates, 58%), followed by
(30 isolates, 15%). Sixty-two strains (18 strains of

her or one ward to another is probable.
The most frequent isolated pathogen was E. coli, and an increasing rate of antibiotic resistance to the commonly prescribed antimicrobial agents such as trimethoprim/sulfamethoxazole and cephalosporins was observed. Moreover, the results of this study showed the presence of clones with ≥80% similarity in E. coli, K. pneumoniae, E. faecium, and B. cepacia complex isolates; therefore, the transmission of nosocomial infections from one patient to another or one ward to another is probable.
The selective Janus-activated kinase inhibitor ruxolitinib (rux) is now widely used to treat myelofibrosis and polycythemia vera due to its remarkable effect of reducing splenomegaly and improving constitutional symptoms. With opportunistic infections secondary to rux constantly reported; however, an increasing number of studies have begun to investigate the mechanism and underlying immunosuppressive effect of rux.
We report two cases of tuberculosis (TB) in primary myelofibrosis patients during rux therapy. The first patient received rux soon after diagnosis, and tracheobronchial TB (TBTB) and bronchoesophageal fistula were found after 4 months. After discontinuation of rux, antituberculosis therapy (ATT) was introduced. The second patient initiated rux due to progressive splenomegaly after 7.5 years of interferon therapy and was diagnosed with disseminated TB after 2 months. He received ATT as well. His rux was maintained due to the high burden of systematic symptoms and splenomegaly. Both myelofibrosisng treatment, rux is recommended to be stopped and active ATT should begin quickly.
The GenoType MTBDR
V2 line-probe assay (LPA) is routinely used in clinical patient management to characterise the susceptibility of
complex to rifampicin (Rif) and isoniazid (INH) directly from sputum and cultured isolates. The laboratory workflow requires skill and three separate areas to minimize contamination and banding pattern interpretation requires experienced laboratory personnel. We explored the use of the RT MTB RIF/INH assay performed on the Abbott
2000 platform as an alternative laboratory platform.
Isolates (n=93) consisting of fully susceptible, Rif- or INH-mono-resistant and multi-drug resistant (MDR) strains were tested on both MTBDR
v2 and RT MTB RIF/INH assays. Both assays target the
and
genes for resistance-detection mutations. Concordance was assessed using percent agreement and the kappa statistic. Those specimens with discordant results were further assessed using Sanger sequencing.
A total of 89% (83/93) of cultured isolates generated successful results on the RT MTB/RIF-INH assay and MTBDR
assays. Of the 10 discordant results, where sequencing was used as the reference method, the RT MTB RIF/INH assays misclassified six resistance isolates, while the LPA misclassified seven.
Overall, the RT MTB RIF/INH demonstrated good agreement with the LPA, and a better correlation with sequencing on discrepant isolates specifically with mutations occurring in codon 511 of the
. The RT MTB RIF/INH therefore can be used to complement existing laboratory algorithms determining Rif and INH resistance profiles, with less emphasis on manual laboratory processing.

COVID-19 (coronavirus disease 2019) has become a global public health emergency since patients were first detected in Wuhan, China, in December 2019. Currently, there are no satisfying antiviral medications and vaccines available.
We reported the treatment process and clinical outcome of a 48-year-old man critically ill COVID-19 patient who received transfusion of allogenic human umbilical cord mesenchymal stem cells (UC-MSCs).
We proposed that UC-MSC transfusion might be a new option for critically ill COVID-19. Although only one case we were shown, more similar clinical cases are inquired for further evidence providing the potential effectiveness of UC-MSC treatment.
