The use of miR-324-5p in diagnosing metabolic syndrome is worth investigating and may benefit patients. The structures and cytotoxic activities of water-soluble polysaccharides were investigated to search for biologically active polysaccharides from the fruit bodies of quinine conks (Fomitopsis officinalis). The decoctions of this medical fungus are actively used in folk medicine in many countries and traditional Chinese medicine. From the fungal extract we prepared, only branched β-glucan had cytotoxic activity among all the water-soluble polysaccharides. This glucan is characterized by a regular structure. Its backbone is formed by 1,3-linked β-D-Glcp residues, of which every third residue is substituted at O-6 by a single β-D-Glcp residue. It has a triple helix conformation according to the data obtained from a colorimetric assay with Congo red dye and is characterized by a high-weight average molar mass (Mw > 800 kDa). β-Glucan possessed cytotoxic activity against HeLa cells (IC50 = 318 ± 47 μg/mL) and induced the formation of apoptotic bodies around most cancer cells at a concentration of 200 μg/mL. It should be noted that extraction with boiling water, which is usually used to obtain extracts and decoctions, is unable to isolate active β-glucan. Active β-glucan can be obtained in an individual state by cold alkali extraction after dehydration of the fruit bodies and removal of the components extractable by boiling water. OBJECTIVE The aim of this study was to analyse the epidemiological impact of murine typhus in patients who required hospitalization in the National Health System (SNS) in Spain between 1997 and 2015. BACKGROUND Murine typhus (MT) is a zoonosis caused by Rickettsia typhi. MT is transmitted from rats, cats, dogs and opossums to humans by their fleas. The clinical picture is characterized by headache, fever, rash and liver function alteration. The prevalence of MT is considered underestimated since most cases are mild and self-limited. However, up to 10% of patients develop serious complications such as pneumonia or acute kidney injury and may even need admission to intensive care units. METHODS This was a retrospective longitudinal descriptive study of inpatients diagnosed with Rickettsia typhi infection (International Classification of Diseases, Ninth Revision, Clinical Modification [ICD-9-CM], 081.0) in Spanish public hospitals between January 1, 1997, and December 31, 2015. Data were obtained from the Minimu Canary Islands and Andalusia registered the highest number of cases. The MBDS is a good approach to study MT hospital management. OBJECTIVES This study aimed to compare clinical courses and outcomes between pregnant and reproductive-aged non-pregnant women with COVID-19, and to assess the vertical transmission potential of COVID-19 in pregnancy. METHODS Medical records of pregnant and reproductive-aged non-pregnant women hospitalized with COVID-19 from January 15 to March 15, 2020 were retrospectively reviewed. The severity of disease, virus clearance time, and length of hospital stay were measured as the primary objective, while the vertical transmission potential of COVID-19 was also assessed. RESULTS Eighty-two patients (28 pregnant women, 54 reproductive-aged non-pregnant women) with laboratory-confirmed COVID-19 were enrolled in this study. Univariate regression indicated no association between pregnancy and severity of disease (OR 0.73, 95% CI 0.08-5.15; p=0.76), virus clearance time (HR 1.16, 95% CI 0.65-2.01; p=0.62), and length of hospital stay (HR 1.10, 95% CI 0.66-1.84; p=0.71). Of the pregnant women, 22 delivered 23 live births, either by cesarean section (17, 60.7%) or vaginal delivery (5, 17.9%), and no neonate was infected with SARS-CoV-2. CONCLUSIONS Pregnant women have comparable clinical courses and outcomes with reproductive-aged non-pregnant women when infected with SARS-CoV-2. No evidence supported vertical transmission of COVID-19 in the late stage of pregnancy, including vaginal delivery. OBJECTIVES We aimed to study Mycobacterium tuberculosis (MTB)-secreted MPT64 as a surrogate of bacterial viability for the diagnosis of active pulmonary tuberculosis (PTB) and for follow-up treatment. METHODS In our proof-of-concept prospective study, 50 PTB patients in Tokyo metropolitan region between 2017 and 2018 were included consecutively and 30 healthy individuals were included. Each PTB patient submitted sputum on Days 0, 14, and 28 for diagnosis and follow-up, and each healthy individual submitted one sputum sample. We performed smear microscopy, Xpert MTB/RIF, MGIT and solid culture, and MPT64 detection on the sputum samples. Ultrasensitive ELISA (usELISA) was used to detect MPT64. The receiver operating characteristic analyses for diagnosis and follow-up revealed the optimal cutoff value of MPT64 absorbance for detecting culture positivity at multiple intervals. RESULTS The sensitivity of MPT64 for diagnosing PTB was 88.0% [95% CI 75.7-95.5] and the specificity was 96.7% [95% CI 82.8-99.9]. The specificity of MPT64 for predicting negative culture results on Day 14 was 89.5% [95% CI 66.9-98.7]. The sensitivity of MPT64 for predicting positive culture results on Day 28 was 81.0% [95% CI 58.1-94.6]. CONCLUSIONS This study revealed that MPT64 is useful for diagnosing active PTB in patients and predicting treatment efficacy at follow-up. BACKGROUND Coronavirus disease 2019 (COVID-19), which was previously known as 2019-novel coronavirus (2019-nCoV), was first reported in Wuhan, China in December 2019. The disease evolved into a serious global emergency, leading to its declaration as a pandemic. DISCUSSION On the African continent, Nigeria is just experiencing the direct effects of this pandemic, having recorded her index case in February 2020, with an increasing number of cases every day and a current case fatality ratio of 0.03 as at 13 April 2020. Although the recorded cases may seem low, it has been forecast that Africa will have some of the worst effects of this disease by the end of the pandemic. Generally, African countries have fragile health systems and this remains a source of concern, especially in the event of increased outbreaks. Nigeria's current national health systems cannot effectively respond to the growing needs of already infected patients requiring admission into intensive care units for acute respiratory diseases and severe acute respiratory syndrome (SARS COV-2) pneumonia. This has grim implications for Nigeria, especially as increased cases loom that may require critical care. Provision of quarantine or isolation facilities and availability of rapid diagnostic kits for fast and reliable testing and diagnosis of the disease can also be a challenge in Africa. CONCLUSION There is an urgent need to put into perspective these realities peculiar to Africa including Nigeria and explore available collective measures and interventions to address the COVID-19 pandemic. OBJECTIVES Numerous studies investigate the advantages of rapid molecular drug susceptibility testing (DST) in comparison to phenotypic DST, but the clinical impact on treating multi/extensively drug resistant TB(M/XDR-TB) is less studied. Therefore, we examined how molecular DST testing may improve MDR-TB treatment management and outcome in Chinese settings. METHODS We performed a comparative study of patient cohorts before and after the implementation of molecular DST diagnosis with Genotype MTBDRsl/MTBDRplus assay in two Chinese hospitals. We collected clinical information including time to sputum culture conversion and final treatment outcome. RESULTS Totally 242 MDR-TB patients were studied including 114 before (pre-implementation group) and 128 after the implementation (post-implementation group) of molecular DST. Time to MDR-TB diagnosis was significantly reduced for patients in the post-implementation group, as compared to the pre-implementation group (median,16 vs 62 days; P  less then  0.001). Patients with early available molecular DST results had a more rapid culture conversion (aHR1.94 95% CI 1.37-2.73; median,12 vs 24 months, respectively; P  less then  0.001) and higher rate of treatment success (68% vs 47%, P  less then   0.01). CONCLUSIONS The use of molecular DST in routine care for MDR-TB diagnosis as compared to phenotypic DST was associated with a decreased time to culture conversion and improved treatment outcome, highlighting its important clinical value. The current reports of COVID-19 focus on the respiratory system, but intestinal infections caused by SARS-CoV-2 are also worthy of attention. Here we report persistence of intestinal SARS-CoV-2 infection in three cases with COVID-19 leads to re-admission after pneumonia resolved. Opioid use disorder (OUD) in pregnant women has increased significantly in recent years. Maintaining these women on sublingual (SL) buprenorphine (BUP) is an evidence-based practice but BUP-SL is associated with several disadvantages that an extended-release (XR) BUP formulation could eliminate. The National Drug Abuse Treatment Clinical Trials Network (CTN) is conducting an intent-to-treat, two-arm, open-label, pragmatic randomized controlled trial, Medication treatment for Opioid-dependent expectant Mothers (MOMs), to compare mother and infant outcomes of pregnant women with OUD treated with BUP-XR, relative to BUP-SL. A second aim is to determine the relative economic value of utilizing BUP-XR. Approximately 300 pregnant women with an estimated gestational age (EGA) of 6-30 weeks, recruited from 12 sites, will be randomized in a 11 ratio to BUP-XR or BUP-SL, balancing on site, EGA, and BUP-SL status (taking/not taking) at the time of randomization. Participants will be provided with study medication and attend weekly medication visits through 12 months postpartum. Participants will be invited to participate in two sub-studies to evaluate the 1) mechanisms by which BUP-XR may improve mother and infant outcomes; and 2) effects of prenatal exposure to BUP-XR versus BUP-SL on infant neurodevelopment. This paper describes the key design decisions for the main trial made during protocol development. This Investigational New Drug (IND) trial uniquely uses pragmatic features where feasible in order to maximize external validity, hence increasing the potential to inform clinical practice guidelines and address multiple knowledge gaps for treatment of this patient population. Recently, there is significant interest in understanding the cost-effectiveness of treatments in spine surgery as healthcare systems in the United States move towards value-based care and alternative payment models. Previous studies have demonstrated comparable outcomes of cervical disc arthroplasty (CDA) and anterior cervical discectomy fusion (ACDF); however, there is a lack of consensus on the cost-effectiveness of CDA to support full adoption. NVP-BSK805 cost Limitations of these cost-analysis studies also exist in the literature including industry-funding, potential selection bias, and varying methods of calculating value. The goal of this narrative review is to provide an overview of the cost-effectiveness of CDA compared to ACDF and potential limitations with cost-analysis studies in spine surgery.
