BACKGROUND: Identifying potentially treatable risk factors for the progression of keratoconus is of great importance. The purpose of this study was to determine the association between blepharitis and keratoconus. METHODS: In this prospective, comparative, observational study, 50 keratoconus participants from the central district of the Clalit Health Services Health Maintenance Organization in Israel underwent comprehensive eye examination. Seventy-two healthy medical personnel of similar ages were randomly chosen as a control group...

Background Treatment of neovascular age-related macular degeneration (nvAMD) under real life conditions may differ from controlled prospective trials with respect to the number of injections and long term preservation of visual acuity. In many instances, intervals for controls and re-injection cannot be maintained as frequently as required. This case series examines actual intervals for control and re-injection visits, in order to estimate how prolonged intervals have an impact on momentary visual acuity and how long term visual outcome is affected...

Background Controlled prospective clinical trials on the treatment of diabetic macular oedema (DME) using anti-VEGF compounds show very good results in visual acuity gain over several years. To date, only limited data are available from comparable studies under real-life settings in clinical routine. However, real-life data from other indications for anti-VEGF treatment suggest that, in clinical routine, gain in visual acuity is less pronounced and cannot be maintained over a longer period of time, which is related to the significantly lower number of injections administered in clinical routine...

Background The evaluation of relationships in clinical case series is complicated by statistical pitfalls, one of which is spurious correlation. In this case, one or more potential factors are actually not related to a target measure, yet it may be wrongly inferred that they are. This may be due to either coincidence or the presence of a one or more confounding unregarded factors. In randomised clinical trials, it is attempted to eliminate such confounding factors or to control them by randomisation. However, this approach is not applicable in retrospective case series, and other statistical methods must be applied, such as multivariate analyses, taking into account all known variables...

Background The posterior tibial plateau is often affected in intra-articular tibial fractures. Moreover, treating these posterior fractures is recognised as an important prognostic factor. Open reduction and internal fixation of lateral and posterior two column tibial plateau fractures can be achieved via a combined reversed L-shape approach and an anterolateral approach in the floating position without intraoperative repositioning of the patient. Material and Methods The operative procedure starts in the posterior position with visualisation of the posterior column after lateral retraction of the medial head of the M...

Urodilatin (UD) and uroguanylin (UGN) have been implicated in the regulation of salt and water homeostasis, particularly in the balance handling of salt intake. In this sense, the aim of the present work was to study the main effects of these peptides in kidneys from animals subjected to high NaCl (2%) intake, during 10 days in metabolic cages. The control group received only normal water, whereas the treated group drank 2% solution of NaCl (NaCl 2%). In addition, we studied effect of subthreshold UD (0.14 nM) and UGN (0...

Neprilysin (NEP, CD10) acts to limit excessive inflammation partly by hydrolyzing neuropeptides. Although deletion of NEP exacerbates intestinal inflammation in animal models, its role in ulcerative colitis (UC) is not well explored. Herein, we aimed to demonstrate changes in NEP and associated neuropeptides at the same time in colonic tissue. 72 patients with UC and 27 control patients were included. Patients' demographic data and laboratory findings, five biopsy samples from active colitis sites and five samples from uninvolved mucosa were collected...

Allostery is a regulatory mechanism in proteins where an effector molecule binds distal from an active site to modulate its activity. Allosteric signaling may occur via a continuous path of residues linking the active and allosteric sites, which has been suggested by large conformational changes evident in crystal structures. An alternate possibility is that the signal occurs in the realm of ensemble dynamics via an energy landscape change. While the latter was first proposed on theoretical grounds, increasing evidence suggests that such a control mechanism is plausible...

INTRODUCTION: Cardiovascular diseases (CVDs) are the most common cause of non-communicable disease mortality in sub-Saharan African (SSA) countries. Gaps in knowledge of CVD conditions and their risk factors are important barriers in effective prevention and treatment. Yet, evidence on the awareness and knowledge level of CVD and associated risk factors among populations of SSA is scarce. This review aimed to synthesize available evidence of the level of knowledge of and perceptions towards CVDs and risk factors in the SSA region...

We studied the effects of various assay temperatures, representing hypothermia (25°C), normothermia (35°C), and hyperthermia (42°C), on the oxidation of lipid-derived fuels in rat skeletal muscle mitochondria of untrained and endurance-trained rats. Adult 4-month-old male Wistar rats were assigned to a training group (rats trained on a treadmill for 8 weeks) or a sedentary control group. In skeletal muscle mitochondria of both control and trained rats, an increase in the assay temperature from 25°C to 42°C was accompanied by a consistent increase in the oxidation of palmitoylcarnitine and glycerol-3-phosphate...

Unlike the fibroblast-like cells formed upon monolayer culture of human mesenchymal stem cells, the natural stem cell niche of the bone marrow and other types of tissues favours the formation of 3-dimensional (3D) cell clusters. The structuring and biological activity of these clusters are regulated by the contacts established by cells with both the basement membrane and neighbour cells and results in their asymmetric division and the consequent maintenance of both a stem population and a committed progeny...

Candida albicans is a virulent human opportunistic pathogen. It evades innate immune surveillance by masking an immunogenic cell wall polysaccharide, β-glucan, from recognition by the immunoreceptor Dectin-1. Glucan unmasking by the antifungal drug caspofungin leads to changes in the nanostructure of glucan exposure accessible to Dectin-1. The physical mechanism that regulates glucan exposure is poorly understood, but it controls the nanobiology of fungal pathogen recognition. We created computational models to simulate hypothetical physical processes of unmasking glucan in a biologically realistic distribution of cell wall glucan fibrils...

BACKGROUND: Long-term non-invasive ventilation (NIV) is an established and increasingly used treatment option for patients with chronic hypercapnic chronic obstructive pulmonary disease (COPD). Following inpatient NIV establishment, inpatient control visits regularly occur thereafter. However, it remains unclear whether such control visits can also be performed in an outpatient setting, which, in turn, would reduce costs, patient burden and the complications related to hospitalization...

BACKGROUND AND OBJECTIVES: The rarity of duodenal gastrointestinal stromal tumors (DGIST) led to only limited data being available on their management and prognosis. We retrospectively analyzed the clinicopathological features, surgical treatments, adjuvant therapy, and prognosis of DGIST. METHODS: Sixty-one patients were identified at diagnosis of primary DGIST from February 2005 to December 2015. One hundred twenty six patients with small intestinal gastrointestinal stromal tutors (GIST) were selected as control groups...

Abdominal aortic aneurysm (AAA) is a silent, progressive disease with a high mortality and an increasing prevalence with aging. Smooth muscle cell (SMC) dysfunction contributes to gradual dilatation and eventual rupture of the aorta. Here we studied phenotypic characteristics in SMC cultured from end-stage human AAA (≥5 cm) and cells cultured from a porcine carotid artery (PCA) model of early and end-stage aneurysm. Human AAA-SMC presented a secretory phenotype and expressed elevated levels of the differentiation marker miR-145 (2...

We investigated the anticaries properties of an adhesive containing dimethylaminododecyl methacrylate (DMADDM) in vivo via a secondary caries animal model. Cavities were prepared in the maxillary first molars of Wistar rats. DMADDM-containing adhesives were applied on one side and commercial adhesives on the opposite side as a control. After a 3-week feeding period to induce secondary caries, the molars were harvested for the evaluation of the secondary caries. Lesion depth (LD) and mineral loss (ML) were measured via a micro-CT method, and a modified Keyes scoring method yielded scores for the caries lesions...

Studies using videotape recordings and respiratory function monitoring have shown that both face mask (FM) application and endotracheal tube (ETT) placement represent a challenge for resuscitators. Hence, there is a strong need for devices that can largely be used independently of individual operator training levels, in order to ensure more reliable support in time-critical situations, such as neonatal resuscitation. The laryngeal mask airway device (LMA) has evolved as a potentially very valuable tool. We conducted a systematic review of studies evaluating the use of the LMA in neonatal resuscitation...
