Pegfilgrastim is a granulocyte colony-stimulating factor used in non-myeloid cancer patients to prevent infections and neutropenic fevers. Although this medication is widely used to induce granulocytosis in pancytopenia patients, there are certain instances where such a situation can cause severe side effects. In this case, we present a patient with a history of metastatic colon cancer who is currently taking pegfilgrastim to counter the agranulocytosis caused by his chemotherapy treatment.

Structured frameworks and theoretical strategies are required to facilitate successful service implementation processes, outcomes and sustainability. This commentary discusses the considerations of what framework (adoption versus adaptation) would be suitable when implementing a new professional pharmacy service to a new environment.

Accumulation of amyloid-beta (Aß) proteins in the ganglion cell layer (GCL) and subsequent retinal ganglion cell (RGC) loss is an established pathological hallmark of the disease. The mechanism through which Aß provokes RGC loss remains unclear.

The immunomodulatory protein macrophage migration inhibitory factor (MIF) promotes neutrophil recruitment to the lung and antagonises responses to glucocorticoids. We hypothesised that MIF promotes glucocorticoid resistance of neutrophilic inflammation in severe asthma.

The receptor for advanced glycation end-products (RAGE) has been implicated in the pathophysiology of chronic obstructive pulmonary disease (COPD). However, it is still unknown whether RAGE directly contributes to alveolar epithelial damage and abnormal repair responses. We hypothesize that RAGE activation not only induces lung tissue damage but also hampers alveolar epithelial repair responses.

MASs are delivered by community pharmacists and non-pharmacist staff. Limited information exists regarding education, training, assessment requirements, and suitability of existing processes to support MAS delivery.

This raises a question of whether poor HRV can predict abnormal elective coronary angiography (ECA).
Aim: The aim of this study was to compare HRV in patients with typical chest pain when they are classified according to ECA outcomes.
Background Minor ailments services are structured pharmacy-based primary health care services that manage minor conditions. Limited training, education and assessment exists to promote the delivery of minor ailments services by pharmacy staff and it is unclear if the existing training and education processes meet professional requirements. Objective To explore the views and experiences of health professional stakeholders such as community pharmacists, intern pharmacists, medicines counter assistants and general medical practitioners with regards to minor ailments services education, training and assessment practices and preferences.
View Article and Find Full Text PDFBackground: The receptor for advanced glycation end products (RAGE) and Toll-like receptor 4 (TLR4) is implicated in COPD. Although these receptors share common ligands and signalling pathways, it is not known whether they act in concert to drive pathological processes in COPD. We examined the impact of RAGE and/or TLR4 gene deficiency in a mouse model of COPD and also determined whether expression of these receptors correlates with airway neutrophilia and airway hyperresponsiveness (AHR) in COPD patients.

Community pharmacy staff may benefit from education and training to deliver MASs. Our objective was to examine the evidence regarding training, education, and assessment requirements associated with the delivery of MASs by community pharmacists and other community pharmacy staff.

Severe respiratory viral infections in infancy predispose to later asthma, however, the processes that mediate tissue damage-induced type-2 inflammation and the origins of airway remodelling remain ill-defined. Here, using a preclinical mouse model of viral bronchiolitis, we find that increased epithelial and mesenchymal high-mobility group box 1 (HMGB1) expression is associated with increased numbers of IL-13-producing type-2 innate lymphoid cell (ILC2s) and the expansion of the airway smooth muscle (ASM) layer.

Activation of the renin-angiotensin-aldosterone system (RAAS) in adipose tissue may represent an important link between obesity and hypertension. This study investigates the effects of oral intake of glucose with and without NaCl on angiotensin II (AngII) and aldosterone in obese and nonobese patients with essential hypertension.

Using mouse models of ovalbumin-induced asthma, previous investigators have established a crucial role for MIF in the development of type 2-mediated eosinophilic asthma. Surprisingly, however, the role of MIF in other phenotypes of asthma has received little attention.

Leukostasis refers to symptomatic hyperleukocytosis and is considered a medical emergency. In pediatric practice, hyperleukocytosis is most commonly described in leukemia and other myeloproliferative disorder, but other etiologies, such as infection, are less commonly mentioned.

Material And Methods: One hundred and fifty-four ECA candidates with a history of typical chest were seen on the same day intended for ECA in the cardiac centre of AlShaab Teaching Hospital, Khartoum, Sudan. The details of the present complaints, characteristics of chest pain, past medical and socioeconomic history were recorded from each subject guided by a questionnaire.
The release of damage-associated molecular patterns (DAMPs) by airway epithelial cells is believed to play a crucial role in the initiation and development of chronic airway conditions such as asthma and chronic obstructive pulmonary disease (COPD). Intriguingly, the classic DAMP high-mobility group box-1 (HMGB1) is detected in the culture supernatant of airway epithelial cells under basal conditions, indicating a role for HMGB1 in the regulation of epithelial cellular and immune homeostasis. To gain contextual insight into the potential role of HMGB1 in airway epithelial cell homeostasis, we used the orthogonal and complementary methods of high-resolution clear native electrophoresis, immunoprecipitation, and pull-downs coupled to liquid chromatography-tandem mass spectrometry (LC-MS/MS) to profile HMGB1 and its binding partners in the culture supernatant of unstimulated airway epithelial cells.

Objective: The aim of this work was to develop an amorphous solid dispersions/solutions (ASD) of a poorly soluble drug, budesonide (BUD) with a novel polymer Soluplus (BASF, Germany) using a freeze-drying technique, in order to improve dissolution and absorption through the nasal route.
Significance: The small volume of fluid present in the nasal cavity limits the absorption of a poorly soluble drug. Budesonide is a corticosteroid, practically insoluble and normally administered as a suspension-based nasal spray.
Autophagy is a ubiquitous cellular mechanism for the targeted lysosomal degradation of various cytosolic constituents, from proteins to organelles. As an essential homeostatic mechanism, autophagy is upregulated in response to numerous environmental and pharmacological stimuli, including starvation, where it facilitates the recycling of essential amino acids. In addition, autophagy plays specific roles within the immune system; it serves as a source of peptides for antigen presentation, a mechanism for the engulfment and degradation of intracellular pathogens and as a key regulator of inflammatory cytokines.

Although many patients with asthma develop type-2 dominated eosinophilic inflammation, a number of individuals develop paucigranulocytic asthma, which occurs in the absence of eosinophilia or neutrophilia. The aetiology of paucigranulocytic asthma is unknown.

However, such effects are extremely elusive via the conventional oral administration. The purpose of the present study was to prepare and characterize the physicochemical properties and the in vivo biodistribution of simvastatin-loaded lecithin/chitosan nanoparticles (SVT-LCNs) suitable for nasal administration in view of an improved delivery of the statins to the brain.
