Neurogenic lower urinary tract dysfunction (NLUTD) represents a severe burden for patients with open spina bifida (OSB). The effect of fetal OSB repair on the urological outcome remains unclear, as controversial data exist. The aim of this study was to further increment existing outcome data and to demonstrate that our earlier published positive preliminary results are not erratic.

Data from standardized urological follow-up appointments of patients with fetal OSB repair operated at our center were analyzed. Data were obtained from urodynamic studies (UDSs) and radiologic exams performed in the newborn (gestational age 37-39 weeks), at ages of 6, 12, 18, and 24 months, and then at yearly intervals.

Of 82 patients (mean age 2.6 years, range 6 months to 7 years), 26 (32%) had a normal bladder function as demonstrated by UDSs. Of the 56 (68%) patients with NLUTD, 29 (51%) patients showed initially a normal UDS, but developed NLUTD in the follow-up, 19 (66%) of them spontaneously and another 10 (34%) in association with growth and development, or surgery of inclusion cysts. Radiologic abnormalities (upper tract dilatation and vesico-uretero-renal reflux) were seen in 15%, mainly patients with NLUTD.

Our results add an important set of information to the existing body of evidence. The data reconfirm our earlier published favorable preliminary results and support other studies that show a possible benefit of prenatal OSB repair on the urological outcome, but they also demonstrate that the positive effect remains limited.

In triple negative breast cancer (TNBC) patients receiving neoadjuvant chemotherapy (NACT), pre-treatment predictors for pathological complete response (pCR) have been reported; however, those for progressive disease (PD) remain unidentified.

We investigated pre-treatment clinicopathological predictors associated with pCR and PD by retrospectively reviewing data for 165 patients treated between 2015 and 2018. Patients with pCR and PD were compared to those without pCR and PD, respectively, using logistic regression and Kaplan-Meier methods.

Lack of androgen receptor (AR) was an independent predictor of pCR, while high histological grade, low Ki-67 index, and incomplete NACT courses were independent predictors of PD. Mean disease-free survival and overall survival were significantly poorer in PD patients than in pCR patients (15.7, 21.3 vs. 52.4, 56.3 months).

Insights into the chemo-resistance mechanisms and exploration of novel targeted agents in subgroups as per AR and Ki-67 status are needed to improve survival outcomes in TNBC patients.

Acute exacerbations of idiopathic pulmonary fibrosis (AE-IPF) are episodes of acute respiratory worsening characterized by diffuse alveolar damage superimposed on usual interstitial pneumonia. Direct hemoperfusion with a polymyxin B-immobilized fiber column (PMX-DHP) is reported to have beneficial effects on the respiratory status and outcome in patients with AE-IPF although its mechanism of action is not fully elucidated.

To investigate whether and how the PMX-immobilized fiber (PMX-F) adsorbs cytokines because reduction of the serum levels of various cytokines has been noted in AE-IPF patients receiving PMX-DHP.

The propensity of recombinant cytokines for adsorption onto PMX-F was examined by incubating cytokines with heparin-coated or uncoated PMX-F for 2 h at 37°C. Cytokines were quantitated by multiplex bead array assay or ELISA.

Interleukin (IL)-8, RANTES, platelet-derived growth factor-bb, and transforming growth factor-β were substantially adsorbed onto PMX-F without heparin coating. The adsorimpacts of PMX-DHP in patients with AE-IPF.

While cochlear implantation may have a positive effect on tinnitus, it is not effective in reducing tinnitus in all patients. This may be due to different patients requiring different strategies of electrical stimulation in order to obtain a positive effect on tinnitus. It is, therefore, important to identify the most effective stimulation strategies to reduce tinnitus. The simplest possible strategy is stimulation by only one electrode. In this study, we investigated tinnitus suppression by electrical stimulation via a single electrode of the cochlear implant.

We performed a listening experiment in 19 adult participants, who had received a unilateral cochlear implant (CI) because of severe bilateral hearing loss. All of these patients had indicated that they suffered from tinnitus. During a 300-s interval, patients listened to blocks of single-electrode stimulation and rated the loudness of the stimulus and any effects on their tinnitus. The 300-s interval included a block of single-electrode stimulationall effect of cochlear implantation on tinnitus, that is, the effect with full-array stimulation, was not correlated with the effectiveness of the single-electrode stimulation on tinnitus.

In conclusion, the effect of single-electrode stimulation on tinnitus is relatively insignificant in comparison to the effect of full-array stimulation. However, in some individual cases, sustained single-electrode stimulation may be beneficial for tinnitus management.

Tobacco use is the leading cause of preventable morbidity and mortality. Existing evidence-based treatments are underutilized and have seen little recent innovation. The success of personal biofeedback interventions in other disease states portends a similar opportunity in smoking cessation. The Pivot Breath Sensor is a personal interactive FDA-cleared (over-the-counter) device that measures carbon monoxide (CO) in exhaled breath, enabling users to link their smoking behavior and CO values, and track their progress in reducing or quitting smoking.

The objective of this study is to assess the Pivot Breath Sensor in people who smoke cigarettes, evaluating changes in attitudes toward quitting smoking, changes in smoking behavior, and use experience.

US adults (18-80 years of age, ≥10 cigarettes per day [CPD]) were recruited online for this remote 12-week study. Participants completed a screening call, informed consent, and baseline questionnaire, and then were mailed their sensor. Participants were asked tor biofeedback via personal CO breath sampling in smoking cessation.

The early neonatal period is the most critical for the newborn’s life. The autopsy is important to understand the cause of death, and find other diagnoses not clinically identified. However, the rate of neonatal autopsy is declining worldwide. This study aims to characterize early neonatal death and the clinical importance of the autopsy, evaluating the concordance between clinical and pathological diagnosis.

Retrospective study of the clinical records of all neonates admitted to a level III Neonatal Intensive Care unit in Portugal who died during the first week of life in 10 consecutive years (2008 – 2017). In order to classify the concordance found between clinical and pathological diagnoses, the modified Goldman classification was used.

During the first week of life, 76 newborns died. The main causes of death were complications related with prematurity and congenital malformations. The autopsy was performed in 50 newborns. Additional findings were found in 62% of the cases, and in 12% findings with important implications for genetic counseling of future pregnancies. There was concordance between the clinical and pathological findings in 38% of cases.

An autopsy was performed more frequently in newborns with greater gestational age. The number of additional diagnoses found at autopsy, including diagnoses with implications for genetic counseling, confirm the importance of performing them.

An autopsy should be proposed to all parents after early neonatal death, given its importance in clarifying the cause of death.

The ability of weakly charged heteroaggregates to adsorb to the oil-water interface favors the formation of highly stable emulsions. A control over the microstructure and rheology of the Pickering emulsion is demonstrated by tuning parameters such as composition, pH, and total concentration of particles. The Pickering emulsions formed under optimal conditions are found to be gel-like and are excellent templates for the fabrication of porous ceramics. Furthermore, the porous mullite ceramic structure which has exceptional thermal and chemical resistance under harsh environments is obtained by drying and sintering of the emulsion template. The phase evolution, microstructure, and porosity of the resulting ceramic are characterized.WD40-repeat (WDR)-containing proteins constitute an evolutionarily conserved large protein family with a broad range of biological functions. In human proteome, WDR makes up one of the most abundant protein-protein interaction domains. Members of the WDR protein family play important roles in nearly all major cellular signalling pathways. Mutations of WDR proteins have been associated with various human pathologies including neurological disorders, cancer, obesity, ciliopathies and endocrine disorders. This review provides an updated overview of the biological functions of WDR proteins and their mutations found in congenital disorders. We also highlight the significant role of WDR proteins in ciliopathies and endocrine disorders. The new insights may help develop therapeutic approaches targeting WDR motifs.Ulcerative colitis (UC) is a major type of inflammatory bowel disease (IBD) and significantly impacts patient quality of life. Previous research revealed that the guanylate cyclase-C (GC-C) signaling pathway is associated with the severity of UC. We aimed to investigate the effect of the GC-C agonist, guanylin (Gn), on inflammatory injury in mice with colitis. An experimental UC model was established in Balb/c mice. Mesalamine served as a positive control. The Gn overexpression vector was administered once per day for 1 week. Intestinal permeability of the mice was measured using fluorescein isothiocyanate-dextran after the treatment. Histopathologic grading was estimated to assess the inflammatory injury of the colon. The expression level of crucial mediators of the GC-C signaling pathway (Gn, Ugn and GC-C) and tight junction proteins (occludin, claudin-1 and ZO-1) was measured in the colon. Additionally, the level of pro-inflammatory cytokines (IL-8 and TNF-α) in serum was measured. After injecting the UC mice with the Gn overexpression vector, the body weight increased, and the frequency of loose stools and bloody stools was decreased.
