A 44-year-old Saudi female presented with poor right eye vision for 3 years. Visual acuity (VA) was 20/400 in the right eye and 20/20 in the left eye. Examination and imaging showed all the typical features of retinitis pigmentosa in the right eye associated with full thickness macular hole (FTMH) and an essentially normal left eye. The case underwent pars plana vitrectomy with internal limiting membrane peeling and gas tamponade that resulted in anatomical closure of the FTMH, but VA remained the same.

Heart failure has emerged as a disease with significant public health implications. Following progression of heart failure, heart and liver dysfunction are frequently combined in hospitalized patients leading to increased morbidity and mortality. Here, we investigated the underlying pathological alterations in liver injury following heart failure. Heart failure was induced using a modified infrarenal aortocaval fistula (ACF) in male Wistar rats. Sham operated and ACF rats were compared for their morphometric and hemodynamic data, for histopathological and ultrastructural changes in the liver as well as differences in the expression of apoptotic factors...

BACKGROUND: Locally advanced esophageal carcinoma (LAEC) represents less than 30% of all diagnosed esophageal carcinoma worldwide. The standard of care for resectable tumours consists of preoperative chemoradiotherapy (CRT) followed by surgery. Despite the curative intent, the prognosis is still poor mainly due to relapse. A multidisciplinary approach is required in order to optimize the therapeutic strategy and follow-up. Differences in outcomes between the two main histological subtypes, adenocarcinoma (ADC) and squamous cell carcinoma (SCC), have been reported...

BACKGROUND: Multiple clinical guidelines are available to improve and standardize the delivery of nutrition support. However, recommendations are not being universally applied at the bedside due to challenges of resources and barriers of knowledge. Assessing the current level of nutrition support practice is the first step to understand the barriers and ultimately implement potential strategies to increase guideline adherence and promote quality nutrition support in hospitals. There are no published data concerning the practice of nutrition support in Lebanese hospitals...

There are several second-line treatment options for patients with renal cell carcinoma after first-line failure of a tyrosine kinase inhibitor, especially with the recent approvals of cabozantinib, nivolumab, and the lenvatinib plus everolimus combination. A lack of reliable biomarkers and an overall lack of prospective head-to-head comparisons make it a challenge to choose a second-line treatment in the clinic. Areas covered: In this review/meta-opinion, we describe the safety profile of the lenvatinib plus everolimus combination in renal cell carcinoma...

Food and nutrition insecurity becomes increasingly worse in areas affected by armed conflict. Children affected by conflict, or in war-torn settings, face a disproportionate burden of malnutrition and poor health outcomes. As noted by humanitarian response reviews, there is a need for a stronger evidence-based response to humanitarian crises. To achieve this, we systematically searched and evaluated existing nutrition interventions carried out in conflict settings that assessed their impact on children's nutrition status...

Gut microbiota dysbiosis has been associated with inflammatory bowel diseases (IBD). In colorectal cancer, the gut microbiota has also been recognized as potentially involved in aggravating or favoring the tumor development. However, very little is known on the structure and role of the microbiota in colitis associated cancer (CAC), an important complication of IBD in human. Here we analyzed the bacterial and fungal composition of the mucosa associated microbiota of patients suffering CAC, sporadic cancer (SC) and of healthy subjects (HS) by barcode sequences analysis on the following cohort: 7 CAC patients, 10 SC patients and 10 HS using 16S (MiSeq) and ITS2 (pyrosequencing) sequencing, for bacteria and fungi respectively...

Exploring the molecular mechanisms that drive the maturation of oligodendrocyte progenitor cells (OPCs) during the remyelination process is essential to develop new therapeutic tools to intervene in demyelinating diseases such as Multiple Sclerosis. To determine whether L-type voltage-gated calcium channels (L-VGCCs) are required for OPC development during remyelination, we have generated an inducible conditional knockout mouse in which the L-VGCC isoform Cav1.2 was deleted in NG2 positive OPCs (Cav1.2(KO))...

Glutathione (GSH) biosynthesis is essential for cellular redox homeostasis and antioxidant defense. The rate-limiting step requires glutamate-cysteine ligase (GCL), which is composed of the catalytic (GCLc) and the modulatory (GCLm) subunits. To evaluate the contribution of GCLc to endothelial function we generated an endothelial-specific Gclc haplo-insufficient mouse model (Gclc e/+ mice). In murine lung endothelial cells (MLEC) derived from these mice we observed a 50% reduction in GCLc levels compared to lung fibroblasts from the same mice...

This study compared the physicochemical and technological properties of the IRGA 410 rice cultivar, obtained from organic and conventional cropping systems, and showed its susceptibility to changes during storage at 0, 6, and 12 mo. The rice conventional cropping system exhibited greater protein, lipids, and ash levels, and a head rice yield. However, organic rice presented greater total carbohydrates, soluble protein, amylose content, 33% greater free phenolics, and phenolic acids, but exhibited a greater percentage of stained grains during the storage period...

Brain-derived neurotrophic factor (BDNF) is abundant in the hippocampus and plays critical roles in memory and synapse formation, as well as exerting antidepressant-like effects in psychiatric disorders. We previously reported that BDNF is expressed in salivary glands and affects blood BDNF content. However, the function of salivary BDNF remains unclear. The aim of this study was to generate transgenic mice overexpressing BDNF in the salivary glands. Hence, we used the Lama construct (hemagglutinin (HA)-tagged mouse Bdnf cDNA) to specifically express BDNF in mouse salivary glands...

RATIONALE: Primary graft dysfunction (PGD) is a form of acute lung injury that occurs after lung transplantation. The definition of PGD was standardized in 2005. Since that time, clinical practice has evolved and this definition is increasingly used as a primary endpoint for clinical trials; therefore, validation is warranted. OBJECTIVE: We sought to determine whether refinements to the 2005 consensus definition could further improve construct validity. METHODS: Data from the Lung Transplant Outcomes Group multi-centered cohort was used to compare variations to the PGD definition, including alternate oxygenation thresholds, inclusion of additional severity groups, and effects of procedure type and mechanical ventilation...

Boron neutron capture therapy (BNCT) is based on selective accumulation of B-10 carriers in tumor followed by neutron irradiation. We demonstrated, in 2001, the therapeutic effect of BNCT mediated by BPA (boronophenylalanine) in the hamster cheek pouch model of oral cancer, at the RA-6 nuclear reactor. Between 2007 and 2011, the RA-6 was upgraded, leading to an improvement in the performance of the BNCT beam (B2 configuration). Our aim was to evaluate BPA-BNCT radiotoxicity and tumor control in the hamster cheek pouch model of oral cancer at the new "B2" configuration...

REVIEW
Emma R McIvor, R Andrew McIvor
Tiotropium is a long-acting muscarinic antagonist (LAMA) that exerts its bronchodilatory effect by blocking endogenous acetylcholine receptors in the airways. Its safety and efficacy are well established for the treatment of COPD, and it is now being recognized for its role in improving lung function and control in asthma. This review discusses the evolving role of tiotropium delivered by the Respimat(®) in patients across the range of asthma severities and ages, and provides an overview of safety and efficacy data...

Chronic obstructive pulmonary disease (COPD), a complex progressive disease, is currently the third leading cause of death worldwide. One recommended treatment option is fixed-dose combination therapy of an inhaled corticosteroid (ICS)/long-acting β-agonist. Clinical trials suggest pressurized metered-dose inhalers (pMDIs) and dry powder inhalers (DPIs) show similar efficacy and safety profiles in COPD. Real-world observational studies have shown that combination therapy has significantly greater odds of achieving asthma control when delivered via pMDIs...
