Chronic obstructive pulmonary disease (COPD) accounts for the majority of deaths from chronic lower respiratory diseases, the third leading cause of death in the United States in 2015 and the fourth leading cause in 2016.* Major risk factors include tobacco exposure, occupational and environmental exposures, respiratory infections, and genetics.† State variations in COPD outcomes (1) suggest that it might be more common in states with large rural areas. To assess urban-rural variations in COPD prevalence, hospitalizations, and mortality; obtain county-level estimates; and update state-level variations in COPD measures, CDC analyzed 2015 data from the Behavioral Risk Factor Surveillance System (BRFSS), Medicare hospital records, and death certificate data from the National Vital Statistics System (NVSS)...

<p>BACKGROUND: Many patients with moderate plaque psoriasis are undertreated despite broadening treatment options. In the phase IV UNVEIL study, oral apremilast demonstrated efficacy and safety in systemic-naive patients with chronic moderate plaque psoriasis with lower psoriasis-involved body surface area (BSA; 5%-10%) during the 16-week, double-blind, placebo-controlled phase. We describe efficacy and safety of apremilast in this population through week 52 in UNVEIL.</p> <p>METHODS: Patients with moderate plaque psoriasis (BSA 5%-10%; static Physician's Global Assessment [sPGA] score of 3 [moderate]) and naive to systemic therapies for psoriasis were randomized (2:1) to receive apremilast 30 mg twice daily or placebo for 16 weeks...

The purpose of this study was to examine the neuronal expression of apoptotic markers in the rostral medulla of a newly characterized dataset of sudden unexpected death in infancy (SUDI), and to determine the impact of diagnostic groupings on these findings and whether they pertain to the intrinsic apoptotic pathway. Immunohistochemical staining was quantified to determine the percentage of neurons positive for active caspase-9 (specific to the intrinsic apoptotic pathway), active caspase-3 (common to the intrinsic and extrinsic apoptotic pathways) and Terminal deoxynucleotidyl transferase mediated dUTP nick-end labelling (TUNEL) (labels DNA fragmentation) in nine nuclei of the rostral medulla...

DNases are abundant among the pathogenic streptococci, with most species harbouring genes for at least one. Despite their prevalence, however, the role for these extracellular enzymes is still relatively unclear. The DNases of the Lancefield group A Streptococcus, S. pyogenes are the best characterized, with a total of eight DNase genes identified so far. Six are known to be associated with integrated prophages. Two are chromosomally encoded, and one of these is cell-wall anchored. Homologues of both prophage-associated and chromosomally encoded S...

BACKGROUND: Respiratory tract infections (RTIs) are a major morbidity factor contributing largely to health care costs and individual quality of life. The aim of the study was to test whether obesity (BMI ≥ 30 kg/m2 ) is one of the risk factors underlying frequent RTIs in the German adult population. METHODS: We recruited 1455 individuals between 18 to 70 years from a cross-sectional survey on airway infections in Germany and invited them to self-report in diaries incident RTIs experienced during three consecutive winter/spring seasons...

Suttonella indologenes is a Gram-negative, aerobic coccobacillus of Cardiobacteriaceae family and its natural habitat is the mucous membranes of the upper respiratory system. The literature includes limited number of case reports concerning fatal endocarditis due to infection in the prosthetic heart valves caused by the aforementioned microorganism. However, there is no information on extracardiac involvement due to this microorganism. Here, we present a peritonitis case caused by Suttonella indologenes in a patient receiving continuous ambulatory peritoneal dialysis...

BACKGROUND: Fever is among the most common symptoms of people living in Africa, and clinicians are challenged by the similar clinical features of a wide spectrum of potential aetiologies. AIM: To summarise recent studies of fever aetiology in sub-Saharan Africa focusing on causes other than malaria. SOURCES: A narrative literature review by searching the MEDLINE database, and recent conference abstracts. CONTENT: Studies of multiple potential causes of fever are scarce, and for many participants the infecting organism remains unidentified, or multiple co-infecting microorganisms are identified, and establishing causation is challenging...

Postnasal drip (PND)-related cough is a very common symptom in patients with upper respiratory tract infections (URTIs). At present, there is not a standard treatment for postnasal drip and postnasal drip-related cough. The aim of this pilot study was to evaluate the efficacy of a specific salso-bromo-iodine thermal water containing hyaluronic acid and grapefruit seed extract (SBI-H-GSE) comparing it with a normal saline solution in children with URTIs who refer PND-related symptoms. The study was randomized, single-blind, and controlled...

Sinus infections can be complicated by ocular infections and, in late phases, by brain parenchyma infection. The article debates the case of a 12-year-old patient suffering from paucisymptomatic maxillo-spheno-ethmoidal rhinosinusitis, which was later complicated by orbital cellulitis, ending with the development of a brain abscess. The treatment is complex, initially targeting the source of the infection through draining the collection by middle maxillary antrostomy and anterior posterior ethmoidectomy, then the ablation of the brain abscess and postoperatively with prolonged massive antibiotherapy...

BACKGROUND Systemic capillary leak syndrome (SCLS) (Clarkson's disease) is a rare disorder of unknown etiology, characterized by transient episodes of hypotension, and the microvascular leak of fluids into the peripheral tissues, resulting in edema. Between 80-90% of patients with SCLS have a concomitant monoclonal gammopathy. Although translational in vitro studies have implicated vascular endothelial barrier dysfunction in the etiology of SCLS, the etiology and disease associations in clinical cases remain unknown...

BACKGROUND: Acute asthma exacerbations and pneumonia are important causes of morbidity and mortality in children and may coexist in the same children, although symptom overlap may lead to difficulties in diagnosis. Microbial and viral diversity and differential abundance of either may play an important role in infection susceptibility and the development of acute and chronic respiratory diseases. OBJECTIVES: To describe the virome and bacteriome present in the upper respiratory tract of hospitalized children with a clinical diagnosis of asthma and pneumonia during an acute exacerbation and an acute respiratory illness ARI episode respectively...

Human influenza viruses preferentially bind to sialic acid-α2,6-galactose (SAα2,6Gal) receptors, which are predominant in human upper respiratory epithelia, whereas avian influenza viruses preferentially bind to SAα2,3Gal receptors. However, variants with amino acid substitutions around the receptor-binding sites of the hemagglutinin (HA) protein can be selected after several passages of human influenza viruses from patients' respiratory samples in the allantoic cavities of embryonated chicken eggs. In this study, we detected an egg-adapted HA S190R mutation in the pandemic H1N1 virus 2009 (pdmH1N1), and evaluated the effects of this mutation on receptor binding affinity and pathogenicity in mice...

Some considerations will be expressed in consideration of the commentary previously published. In particular, we underline that no other medications were administered to the patients during the study period and any clinical evaluation was postponed in case of acute upper respiratory tract infection in the previous 14 days. We strongly advocate antibiotic treatment during any acute otitis media episode, and we agree that topically administered hyaluronic acid should be considered as a supporting treatment, "complementary to traditional therapies" in children with recurrent disease...
