Epidemiology and Clinical Outcomes of Infections: A Six-Year Retrospective Study.

: Anaerobic bacteria like can lead to severe and life-threatening infections. The inherent complexities in the isolation of these bacteria may result in diagnostic and therapeutic delays, thereby escalating both morbidity and mortality rates. We aimed to examine data from patients with infections due to to gain insights into the epidemiology and clinical outcomes of patients with these infections.

The use of selexipag, a prostacyclin receptor analog, for treatment of severe pulmonary artery hypertension during pregnancy, a case report.

Pregnancy in patients with pulmonary artery hypertension (PAH) is associated with high mortality and morbidity. Despite the risks, more patients with PAH are becoming pregnant. Case reports and case series have described the use of IV epoprostenol in these patients with some success.

Ototoxicity monitoring through the eyes of the treating physician: Perspectives from pulmonology and medical oncology.

Objectives: Integrating audiological management into the care pathways of clinical specialties that prescribe ototoxic medications for essential, often life-preserving medical care that is critical for early hearing loss identification and remediation. Research shows that successful implementation of a new health service or intervention requires alignment of goals among provider groups, institutional leadership and patients. Thoughtful consideration of the physician's viewpoints about ototoxicity and its implications for treatment planning is, therefore, important for the implementation and enduring success of an ototoxicity monitoring programme (OMP).

Lung function and gas exchange in Eisenmenger syndrome and their impact on exercise capacity and survival.

Background: Eisenmenger physiology may contribute to abnormal pulmonary mechanics and gas exchange and thus impaired functional capacity. We explored the relationship between lung function and gas exchange parameters with exercise capacity and survival.

Methods: Stable adult patients with Eisenmenger syndrome (N=32) were prospectively studied using spirometry, lung volumes, diffusion capacity, and blood gas analysis, as well as same day measurement of 6-minute walk distance and cardiopulmonary maximal treadmill exercise.

An opportunistic infection associated with ruxolitinib, a novel janus kinase 1,2 inhibitor.

We report a case of Cryptococcus neoformans pneumonia in a patient taking ruxolitinib, a janus kinase 1,2 inhibitor approved for the treatment of myelofibrosis. We hypothesize that ruxolitinib contributed to this infection through its effects on cell-mediated immunity. Clinicians should be aware of the potential for intracellular or opportunistic infections associated with this novel drug class.

Association of interleukin 23 receptor gene with sarcoidosis.

Interleukin 23 receptor (IL23R) gene has been reported as a genetic factor strongly associated with inflammatory bowel disease, psoriasis, and ankylosing spondylitis. We investigated the association between IL23R gene single nucleotide polymorphisms (SNPs) and susceptibility to sarcoidosis, including the clinical manifestation of uveitis. Ninety-one sarcoidosis subjects (58 with and 33 without uveitis) and 104 healthy controls were genotyped for eleven IL23R SNPs.

Instantaneous within-patient diversity of Pseudomonas aeruginosa quorum-sensing populations from cystic fibrosis lung infections.

In the opportunistic pathogen Pseudomonas aeruginosa, acyl-homoserine lactone (acyl-HSL) quorum sensing (QS) regulates biofilm formation and expression of many extracellular virulence factors. Curiously, QS-deficient variants, often carrying mutations in the central QS regulator LasR, are frequently isolated from infections, particularly from cystic fibrosis (CF) lung infections. Very little is known about the proportion and diversity of these QS variants in individual infections.
