Chronic lung diseases, such as chronic obstructive pulmonary disease (COPD) and idiopathic pulmonary fibrosis (IPF) are linked to several mitochondrial alterations. Cigarette smoke (CS) alters the structure and function of mitochondria. OPA1 is the main inner mitochondrial GTPase responsible for the fusion events. OPA1 undergoes proteolytic cleavage from long to short forms during acute stress and mitophagy. However, the exact role of OPA1 isoforms and related proteins during CS-induced mitophagy and COPD is not clear.

Lung tissues from non-smokers, smokers, COPD and IPF were used to determine the relative expression of OPA1 and related proteins. Additionally, we used mouse lungs from chronic (6 months) CS exposure to evaluate the status of OPA1. Primary lung fibroblasts from normal and COPD patients and naked mole rat (NMR) lung fibroblasts, human fetal lung fibroblast (HFL1), mouse embryonic fibroblast from wild type (WT), OPA1
, MFN1 and MFN2
were used to determine the effect of CS on OPA1 isoforms.tophagy/mitochondrial dysfunction in COPD, which may be used as a novel therapeutic target in COPD.
The long OPA1 isoform along with SLP2 and prohibitins play a crucial role in CS-induced lung damage, causing mitophagy/mitochondrial dysfunction in COPD, which may be used as a novel therapeutic target in COPD.
Dual amylin and calcitonin receptor agonists (DACRAs) are novel therapeutic agents that not only improve insulin sensitivity but also work as an adjunct to established T2DM therapies. DACRAs are currently administered once daily, though it is unknown whether DACRAs with increased plasma half-life can be developed as a once-weekly therapy.

The invitro potencies of the KBP-066A and KBP-066 (non-acylated) were assessed using reporter assays. Acylation functionality was investigated by a combination of pharmacokinetics and acute food intake in rats. invivo efficacies were investigated head-to-head in obese (HFD) and T2D (ZDF) models.

In invitro, KBP-066A activated the CTR and AMY-R potently, with no off-target activity. Acylation functionality was confirmed by acute tests, as KBP-066A demonstrated a prolonged PK and PD response compared to KBP-066. Both compounds induced potent and dose-dependent weight loss in the HFD rat model. In ZDF rats, fasting blood glucose/fasting insulin levels (tAUC) were reduced by 39%/50% and 36%/47% for KBP-066 and KBP-066A, respectively. This effect resulted in a 31% and 46% vehicle-corrected reduction in HbA1c at the end of the study for KBP-066 and KBP-066A, respectively.

Here, we present pre-clinical data on an acylated DACRA, KBP-066A. The invivo efficacy of KBP-066A is significantly improved compared to its non-acylated variant regarding weight loss and glycemic control in obese (HFD) and obese diabetic rats (ZDF). This compendium of pre-clinical studies highlights KBP-066A as a promising, once-weekly therapeutic agent for treating T2DM and obesity.

Exclusive enteral nutrition (EEN) is used to treat pediatric Crohn's disease (CD), but therapeutic benefits are variable, and EEN can lead to microbial dysbiosis. Because of reported lower efficacy EEN is not routinely used to treat pediatric ulcerative colitis (UC). Inulin-type fructans (IN) beneficially modulate the gut microbiome and promote expansion of anti-inflammatory immune cells. We hypothesized that enriching EEN with IN (EEN IN) would enhance treatment efficacy. To test this, we examined the effects of EEN IN on colitis development, the gut microbiome, and CD4
T cells using an adoptive T-cell transfer model of colitis.

TCR-β deficient (
) mice were randomized to 1 of 4 groups (1) Control, (2) Chow, (3) EEN, and (4) EEN IN, and naive CD4
T cells were adoptively transferred into groups 2-4, after which mice were monitored for 5 weeks before experimental endpoint.

Mice fed EEN IN showed greater colitis protection, with colonic shortening, goblet cell, and crypt density loss reduced compared with EEN fed mice and reduced disease activity and immune cell infiltration compared with chow fed mice, and less crypt hyperplasia and higher survival compared with both groups. EEN IN mice had less deterioration in the colonic mucus layer and had increased levels of Foxp3
IL-10
and Rorγt
IL-22
and reduced levels of Tbet
IFNγ
and Tbet
TNF
CD4
T cells. EEN IN also led to higher butyrate concentrations, Bifidobacterium spp. and Anaerostipes caccae relative abundance, and lower [Clostridium] innocuum group spp. and Escherichia-Shigella spp relative abundance.

The EEN IN group showed reduced colitis development as compared with the chow and EEN groups. This highlights the potential benefits of EEN IN as a novel induction therapy for pediatric CD and UC patients.

Reduced forced expiratory flow between 25% and 75% of vital capacity percent predicted (FEF
%) representing small airway dysfunction (SAD) was associated with asthma development and progression.

To investigate whether FEF
% was superior to forced expiratory volume in 1 second in predicted (FEV
%) in reflecting asthma features in adult patients.

A retrospective spirometry dataset comprising 1801 adult patients with confirmed asthma and a subgroup of 332 patients having detailed clinical data were used to explore the association of FEF
% and/or FEV
% with clinical features of asthma.

Of the 1801 subjects, FEV
% and FEF
% ranged from 136.8% to 10.2% and 127.3% to 3.1%, respectively. FEF
% < 65% was present in 1,478 (82.07%) of patients. FEF
% was strongly correlated with matched FEV
% (r=0.900, P < .001). FEF
% and FEV
% were both correlated with airway hyperresponsiveness (r= 0.436, P<.001; r= 0.367, P < .001), asthma control test score (r=0.329, P < .001; r= 0.335, P < .00.
FEF25-75% represented small airway function and was more sensitive at reflecting airway hyperresponsiveness, inflammation, and disease severity as compared with FEV1% in patients with asthma. Our data suggest further assessment of FEF25-75% in asthma management, particularly for those with SAD who present normal FEV1%.
Rapid drug desensitization (RDD) becomes a crucial procedure to allow treatment continuation in patients who suffer drug hypersensitivity reactions (DHRs) tochemotherapeutic (CMT) and biological agents (BA).

The aim of the study was to compare the efficacy and safety of a one-bag dilution protocol (1DP) with a conventional three-bag dilution protocol (3DP) for desensitization of patients with CMT or BA hypersensitivity.

Retrospective analysis of patients with immediate DHRs to CMT or BA who underwent at least 1 RDD procedure in our department between 2014 and 2019 was performed. Demographical data, clinical history, skin tests, tryptase levels, and risk assessment were registered. The safety, tolerability, occurrence, and severity of breakthrough reactions (BTR) with 3DP and 1DP were compared.

After the allergy workup, 157 patients fulfilled criteria to undergo RDD (137 females, mean age 60.44 ± 12.6 years). A total of 639 RDDs (543 CMT and 96 BA) were performed using 3DP in 205 (48 patients) and 1DP in 434 (109 patients). Almost all procedures (636) were completed successfully. No BTR occurred in the first RDD in 52% and 51% of the 3DP and 1DP, respectively. see more Most BTR were mild. Moderate-severe BTR occurred in 17% with 3DP and 9% with 1DP. There were no statistical differences between protocols regarding the rate and severity of BTR.

RDD with 1DP to CMT and BA has equivalent outcomes to a 3DP desensitization in a selected population of patients in terms of efficacy, tolerability, and safety. Moreover, 1DP reduces the time required for RDD and simplifies the logistics.

Eosinophilic esophagitis (EoE) has increased rapidly and has been well characterized. However, no nationwide survey has been conducted regarding non-esophageal eosinophilic gastrointestinal disorders (non-EoE EGIDs), and they remain poorly understood.

To compare the clinical features and natural histories of non-EoE EGIDs and EoE by using the same questionnaire, for all ages.

We conducted a nationwide hospital-based survey of patients who visited hospitals from January 2013 through December 2017. We randomly selected 10,000 hospitals that perform endoscopy. We analyzed the demographics, symptoms, gastrointestinal histology, treatments, and natural histories of EoE and non-EoE EGIDs.

A total of 2906 hospitals responded to the questionnaire. We identified 1542 patients and obtained detailed data for 786 patients, consisting of 39% EoE and 61% non-EoE EGIDs. The clinical characteristics were analyzed for patients who met the "definite" criteria that excluded comorbidities. Non-EoE EGIDs showed no gender difference, whereas EoE was male-predominant. Tissue eosinophilia was often seen in the small intestine (62%) and stomach (49%). The frequency of hypoproteinemia was high (27%) in childhood. Children also had more serious symptoms and complications than adults restriction of daily life activity (P= .009), failure to grow/weight loss (P= .008), and surgery (P= .01). For both diseases, the most common natural history was the continuous type 66% (95% confidence interval [CI] 58-74) in EoE and 64% (95% CI 55-72) in non-EoE EGIDs.

The percentage of persistent patients with non-EoE EGIDs was almost the same as those with EoE. Complications were more frequent in children than in adults.

In this paper, we review the current literature on localized cutaneous argyria, highlight its clinical and histologic diagnostic features, and then discuss the clinical and histological differential diagnoses for blue-gray skin and black dermal pigment, respectively. We also discuss the utility of ancillary techniques, such as deeper histologic levels, special stains, darkfield microscopy, and advanced micro-analytical techniques in helping diagnose localized cutaneous argyria. Furthermore, we emphasize that a thorough clinical history and astute clinico-pathologic correlation can be the most important diagnostic techniques in correctly diagnosing this rare disorder. Our review aims serve as a reminder to clinicians and pathologists of the importance of including localized cutaneous argyria in the clinical and histological differential diagnosis of pigmented lesions.
