We studied the value of serum interleukin-8 (IL-8) and procalcitonin (PCT) in the early diagnosis of early severe bacterial infection in 58 critically ill ventilated neonates. ELISA was used for determining IL-8 and immunoluminometric assay for PCT. IL-8 and PCT were compared with routinely used serum C-reactive protein (CRP). Neonates were divided into four groups: Ia - proven severe bacterial infection (n = 9), Ib - clinical sepsis (n = 16), II - respiratory distress without bacterial infection (n = 12), and III - various types of neonatal distress (n = 21). Sera were collected on admission, at 24 h and 48 h after admission. There was no significant difference between groups Ia and Ib for either parameter at any time interval. Significant difference was found between group Ia+b (septic neonates) and group II for PCT and CRP at 24 and 48 h, but not for IL-8. There was no difference between group Ia+b and group III except for CRP at 24 h. Diagnostic accuracy was best for PCT on admission and for CRP at 24 h. Serum PCT and IL-8 are not specific markers for early severe bacterial infection in critically ill neonates and are not better than CRP.

Acute rhinosinusitis causes more than 30 million patients to seek health care per year in the United States. Respiratory tract infections, including bronchitis and sinusitis, account for 75% of outpatient antibiotic prescriptions in primary care. Sinusitis is a clinical diagnosis; the challenge lies in distinguishing between the symptoms of bacterial and viral sinusitis.

Dysuria, a feeling of pain or discomfort during urination, is often caused by urinary tract infection but can also be due to sexually transmitted infection, bladder irritants, skin lesions, and some chronic pain conditions. History is most often useful for finding signs of sexually transmitted infection, complicated infections, lower urinary symptoms in males, and noninfectious causes. Most patients presenting with dysuria should have a urinalysis performed.

Tick-borne spotted fever rickettsioses (SFRs) continue to cause severe illness and death in otherwise-healthy individuals due to lack of a timely and reliable diagnostic laboratory test. We recently identified a diagnostic biomarker for SFRs, the putative N-acetylmuramoyl-l-alanine amidase RC0497. Here, we developed a prototype laboratory test that targets RC0497 for diagnosis of SFRs.

Background: Maternal tetanus toxoid (MTT) vaccination during pregnancy remains an important factor for reducing infant mortality globally, especially in developing nations, including Bangladesh. Despite commendable progress in reducing child mortality through widespread MTT vaccination during pregnancy, the issue still exists. This analysis explores the impact of MTT vaccination on neonatal mortality in Bangladesh and identifies associated factors.

Macrophages express pattern recognition and cytokine receptors that mediate proinflammatory signal transduction pathways to combat microbial infection. To retaliate against such responses, pathogenic microorganisms have evolved multiple strategies to impede innate immune signaling. Recent studies demonstrated that YopJ suppression of TAK1 signaling during Yersinia pseudotuberculosis infection promotes the assembly of a RIPK1-dependent death-inducing complex that enables caspase-8 to directly cleave and activate gasdermin D (GSDMD).
