Previous studies indicated that single-nucleotide polymorphisms (SNPs) of genes coding for toll-like receptors (TLRs) and toll-interacting protein (TOLLIP) may be involved in the pathogenesis of pulmonary tuberculosis (PTB). This study was designed to investigate potential associations between the polymorphisms in TLR2, TLR4, and TOLLIP and susceptibility to latent tuberculosis infection (LTBI) or subsequent PTB in a Chinese Han population. A total of 209 PTB and 201 LTBI patients and 204 healthy control subjects (HCS) were enrolled in our study...

Background: Prematurity is one of the leading causes of neonatal and under-five mortalities globally and also in India. It is an important determinant of short- and long-term morbidities in infants and children. Unfortunately, risk factors of majority of preterm births (PTBs) remain unexplained which calls for appropriate action. There is a dearth of community-based research on PTB and its risk factors, especially in high burden countries like India. Objectives: The objective of the study was to explore different risk factors for PTB...

BACKGROUND: Preterm birth (PTB) is one of the leading causes of perinatal morbidity and mortality. Clinical data suggests that low dose aspirin may decrease the rate of overall PTB, but investigators have speculated that this is likely due to a decrease in medically indicated PTB through its effect on the incidence of preeclampsia and other placental disease. We hypothesized that low dose aspirin may also impact the mechanism of spontaneous preterm labor. OBJECTIVE: Our objective was to determine whether low dose aspirin reduces the rate of spontaneous PTB in nulliparous women without medical co-morbidities...

PROBLEM: Oxidative stress (OS)-induced, p38 mitogen-activated protein kinase (p38MAPK)-mediated chorioamniotic senescence and inflammation (senescence-associated secretory phenotype [SASP]) are associated with parturition. In response to OS-inducing risk factors, premature senescence contributes to preterm premature rupture of the membranes (pPROM) and spontaneous preterm birth (PTB). We determined the effect of simvastatin, rosuvastatin, and progesterone in downregulating p38MAPK-mediated senescence and SASP...

BACKGROUND: The treatment success rate of pulmonary tuberculosis (PTB) patients aged 64 years and below in Japan, a tuberculosis (TB) middle-burden country with a notification of 13.9 per 100,000 populations in 2016, has been fluctuating around 70% for some years. In order to improve treatment outcome, it is critical to address those lost to follow-up (LTFU). The objective of the study therefore was to describe the characteristics of, and analyze the risk factors for those LTFU among pulmonary TB patients aged between 15 and 64, and discuss policy implications...

Simulation models can predict the outcome of different strategies for the control and eradication of paratuberculosis (PTB) in dairy herds. Two main transmission modes have previously been used to simulate the spread of PTB: direct (contact between animals) and indirect (through the environment). In addition, previous models were calibrated to either low or high within-herd prevalence levels, which we refer to as normal and low hygiene levels, respectively. We simulated both direct and indirect transmission with the same model in both normal and low hygiene level scenarios...

Human immunodeficiency virus (HIV) infection is a major risk factor for the development of active tuberculosis (TB), one of the deadliest infectious diseases globally. The high mortality associated with the disease can be reduced by early diagnosis and prompt antituberculous treatment initiation. Facilities in TB-endemic regions are increasing the use of nucleic acid amplification (e.g., GeneXpert), which provides rapid results but may have suboptimal sensitivity in HIV-associated TB. Our objective was to evaluate the current practices for TB diagnosis at Edendale Hospital, a large regional hospital in KwaZulu-Natal, South Africa-a TB-endemic region with high HIV prevalence...

Vaccination against paratuberculosis (PTB) in goats is a cost-effective control strategy, and is also effective as regards preventing the onset of clinical cases. However, it causes interference in the diagnostic tests used in the control of tuberculosis (TB). A group of 99 goats from a herd with no history of TB or PTB infection was vaccinated against PTB at seven months of age. They then underwent consecutive intradermal tests [single (SIT) and comparative (CIT) intradermal tuberculin tests), interferon-gamma release assays (IGRA) and two serological tests (p22_CE and DR-ELISA) every three months, until the interference disappeared...

Few studies have examined contributions of paternal factors to birth outcomes. Weathering is a pattern of increasing rates of adverse birth outcome with increasing maternal age. This study evaluates for an association between paternal involvement and weathering in the context of preterm birth (PTB, <37 weeks) among non-Hispanic African-American and non-Hispanic White women with and without lifelong exposure to neighborhood poverty. Using the Illinois transgenerational dataset with appended US census income information of infants (1989-1991) and their mothers (1956-1976), we compared infants of women by degree of paternal involvement: married, unmarried with father named on birth certificate, and unnamed father...

The frequently applied narrow and non-standard transverse dose profiles of intensity modulated photon-beam radiotherapy, lacking lateral secondary electron equilibrium, require the use of high-resolution dosimetry detectors, and small air-filled detectors are recommended as the reference detectors for cross-calibration of the high-resolution detectors. The present study focuses on the dosimetric properties of a novel cylindrical ionization chamber, the PTW Semiflex 3D 31021. The chamber's effective point of measurement was found to lie at (0...

BACKGROUND: IL-10 family cytokines are associated with the host immune response to pulmonary tuberculosis (PTB), but their association with host response in tuberculous lymphadenitis (TBL) is not known. METHODS: Hence, we examined the circulating levels of the whole panel of IL-10 family cytokines in TBL (n = 44) and compared them to the levels in PTB (n = 44) and healthy control (HC, n = 44) individuals. We also assessed the pre and post-treatment cytokine levels in TBL individuals following the completion of anti-tuberculosis treatment (ATT)...

Preterm birth (PTB) is the leading cause of newborn deaths around the world. Spontaneous preterm birth (sPTB) accounts for two-thirds of all PTBs; however, there remains an unmet need of detecting and preventing sPTB. Although the dysregulation of the immune system has been implicated in various studies, small sizes and irreproducibility of results have limited identification of its role. Here, we present a cross-study meta-analysis to evaluate genome-wide differential gene expression signals in sPTB. A comprehensive search of the NIH genomic database for studies related to sPTB with maternal whole blood samples resulted in data from three separate studies consisting of 339 samples...

SETTING: Pre-diabetes mellitus (pre-DM) and DM increase the risk of developing tuberculosis (TB). Screening contacts of TB patients for pre-DM/DM and linking them to care may mitigate the risk of developing TB and improve DM management. OBJECTIVE: To measure the prevalence of pre-DM/DM and associated factors among the adult household contacts (HHCs) of pulmonary TB patients. METHODS: Between August 2014 and May 2017, adult HHCs of newly diagnosed adult PTB patients in Pune and Chennai, India, had single blood samples tested for glycosylated haemoglobin (HbA1c) at enrolment...
