Although oxygen added to nonaqueous lithium-mediated electrochemical ammonia synthesis (LiMEAS) enhances Faradaic efficiency, its effect on chemical stability and byproducts requires understanding. Therefore, standardized high-resolution gas chromatography-mass spectrometry and nuclear magnetic resonance were employed. Different volatile degradation products have been qualitatively analyzed and quantified in tetrahydrofuran electrolyte by adding some oxygen to LiMEAS. Electrodeposited lithium and reduction/oxidation of the solvent on the electrodes produced organic byproducts to different extents, depending on the oxygen concentration, and resulted in less decomposition products after LiMEAS with oxygen. The main organic component in solid-electrolyte interphase was polytetrahydrofuran, which disappeared by adding an excess of oxygen (3 mol %) to LiMEAS. The total number of byproducts detected was 14, 9, and 8 with oxygen concentrations of 0, 0.8, and 3 mol %, respectively. The Faradaic efficiency and chemical stability of the LiMEAS have been greatly improved with addition of optimal 0.8 mol % oxygen at 20 bar total pressure.In patients with heart failure (HF) with reduced ejection fraction (HFrEF), malnutrition can be associated with intestinal congestion and systemic inflammation. These relationships have not been fully investigated in HF with mildly reduced EF (HFmrEF) and with preserved EF (HFpEF). We analyzed 420 patients with HF who underwent right heart catheterization. The relationships between hemodynamic parameters, C-reactive protein, and the controlling nutritional (CONUT) score were investigated in HFrEF, HFmrEF and HFpEF. The CONUT score of all patients was 2 [1, 4] (median [interquartile range]), and was not significantly different between the left ventricular EF (LVEF) categories (2 [1, 3] for HFrEF, 2 [1, 3] for HFmrEF, and 3 [1, 4] for HFpEF, p = 0.279). In multivariate linear regression analyses, there was a significant association between CRP and the CONUT score in HFmrEF and HFpEF, while brain natriuretic peptide and right atrial pressure were significantly associated with the CONUT score in HFrEF. Higher CONUT scores predicted a higher incidence of the composite endpoint of death or HF hospitalization within 12 months without an interaction with LVEF (p = 0.980). The CONUT score was an independent predictor of the composite endpoint, death, and HF hospitalization after adjustment for confounders in the multivariate analysis. In conclusion, inflammation was associated with malnutrition in HFmrEF and HFpEF, while congestion was an independent predictor of malnutrition in HFrEF. Malnutrition predicted worse outcomes regardless of LVEF.

Overactive bladder (OAB) and urinary incontinence (UI) are prevalent in older women. We investigated relations of toileting behaviors and urinary urge cues to OAB and UI in women ≥ 65 years. We tested mediation hypotheses that toileting behaviors lead to higher sensitivity to urinary urge cues (the mediator), which leads to both OAB and UI.

An e-panel was recruited to respond to an electronic survey that included demographic information, Urinary Cues Scale version 2, Toileting Behaviors-Women's Elimination Behaviors (TB-WEB) scale, and the International Consultation on Incontinence Questionnaire Short Forms for Urinary Incontinence (ICIQ-SF-UI) and Overactive Bladder (ICIQ-SF-OAB). Descriptive statistics were conducted; correlation matrices were created to explore relationships among major variables. Regression analyses were conducted to test our mediation hypotheses.

There were 338 respondents with average age 70.9 (SD + 5.55) years. Most were white, overweight or obese, and had UI. Urinary urge cues fully mediated the relationship of TB-WEB with OAB. Urinary urge cues partially mediated the relationship of TB-WEB with UI; the direct effect of toileting behaviors on UI remained significant. Age and body mass index had significant partial correlations with UI but not with OAB.

Toileting behaviors appear to contribute to sensitivity to urinary cues, which are related to both OAB and UI. Toileting behaviors have indirect effects on OAB and both indirect and direct effects on UI. Interventions to change toileting behaviors and extinguish urinary cues are needed.

Behavioral and conditioning factors contribute to UI in older women.

Vaginal laxity (VL) can impair women´s quality of life and there are not many tools aimed at quantitatively addressing this complaint. Sexual distress can be present within this group of patients. The aim of our study is to carry out the cross-cultural adaptation/translation and validation of the Female Sexual Distress Scale-Revised (FSDS-R) for Brazilian Portuguese women with VL.

Women age ≥ 18 years, with VL (n=82), and without VL (n=53) were included. Continuous variables were described in the form of mean/standard deviation or median/range, and Student's t test was used. The Chi-squared test was used for dichotomous variables. Cronbach's alpha coefficient was used for internal consistency and Spearman's correlation was used to assess construct validity (FSDS-R, Female Sexual Function Index [FSFI], and Incontinence Questionnaire Vaginal Symptoms [ICIQ-VS]). A significance level of 5% was established using a two-tailed test.

Women with VL presented more anal/vaginal sexual intercourse than women without VL (p=0.030). All three instruments (FSDS-R, FSFI, and ICIQ-VS) presented discriminant validity between women with and without VL (p<0.001). A high internal consistency (Cronbach´s alpha =0.887) was found in women with VL and without VL (0.917). Regarding construct validity (n=82), there was a strong positive correlation between FSDS-R score and ICIQ-VS scales, except for a weaker correlation between the ICIQ-VS vaginal symptoms subscale (r +0.2788; p=0.013). A moderate negative correlation was found between FSDS-R and all FSFI domains (p<0.001), except for pain (p<0.062).

The Brazilian version of the FSDS-R showed adequate internal consistency and discriminant validity, and a correlation was found with other instruments such as FSFI and ICIQ-VS.

The objective was to examine knowledge regarding pelvic floor disorders (PFDs) among women during the third trimester of pregnancy.

A cross-sectional study was conducted at a large teaching medical center in Israel between June and September 2020. Bozitinib cell line Women in their third trimester (N = 649) were asked to complete the validated Hebrew and Arabic versions of the Prolapse and Incontinence Knowledge Questionnaire (PIKQ). The PIKQ instrument examines the knowledge of two major PFDs urinary incontinence (UI) and pelvic organ prolapse (POP). The study population included women over 18years of age, in the third trimester, who speak and read Hebrew or Arabic fluently. Two separate scores were calculated, one for each section of the PIKQ. The association of questionnaire scores with the different independent variables was examined using Student's t test or one-way ANOVA. Correlations were examined using Pearson's or Spearman's correlation coefficient.

The Hebrew version was filled out by 405 women, and 244 women completed the Arabic version. The average questionnaire scores were 7.65 ± 2.8 and 5.32 ± 2 for the UI and POP sections respectively. Significantly higher average scores in both the UI and the POP sections were noted among health care workers (UI 10.19 ± 2.3 vs 7.34 ± 2.6, p < 0.001; POP 8.27 ± 2.7 vs 4.97 ± 2.6, p < 0.001), women with higher education (p < 0.001 in both parts) and those with higher incomes (p < 0.001 for both parts).

Knowledge of PFD among women in the third trimester of pregnancy in Israel was found to be low. Founding educational programs for targeted groups may improve both the knowledge of PFD and the quality of life for these women.

Intrathecal (IT) idursulfase-IT for the treatment of cognitive impairment is being investigated in pediatric patients with neuronopathic mucopolysaccharidosis II (MPS II) in addition to intravenous idursulfase. In this article, we report the findings for 54 months of idursulfase-IT treatment in an ongoing phase I/II extension trial (NCT01506141).

A total of 15 male participants with neuronopathic MPS II (aged 3-11 years at enrollment) who were previously treated with intravenous idursulfase entered the extension study. Idursulfase-IT 10 mg or 30 mg was administered monthly via an IT drug delivery device or lumbar puncture, if indicated. The primary endpoint was safety and tolerability; secondary endpoints included pharmacokinetics, cerebrospinal fluid glycosaminoglycan levels, and cognitive function.

In total, 15 participants received a median (range) of 50 (18-55) idursulfase-IT doses. Idursulfase-IT was generally well tolerated; there were no life-threatening adverse events (AEs) or deaths. Most serious AEs were related to the IT drug delivery device; only 2 serious AEs were related solely to idursulfase-IT. After treatment with idursulfase-IT, cerebrospinal fluid glycosaminoglycans were decreased in all participants; these decreases were maintained. Cognitive function was stabilized in 3 of 4 testable participants at month55.

These long-term results support the clinical development of idursulfase-IT for patients with MPS II with cognitive impairment.

Desalination using flow electrode capacitive deionization (FCDI) needs to explore the role of ion exchange membranes (IEM) of FCDI. In this study, brackish water was desalinated using FCDI, and anion exchange membranes with different characteristics were used in the FCDI cell to investigate their influence. The result showed that the membrane polymer matrix was the main influencing factor for ion transport. Ion exchange capacity (IEC) has a huge impact that low IEC made the various ion transport priority. Low IEC not only limits ion transport but also leads to ion leakage in seawater. Resistance had a significant blockage to the effect with weak intensity.

Digital health interventions enable services to support people living with dementia and Mild Cognitive Impairment (MCI) remotely. This literature review gathers evidence on the effectiveness of digital health interventions on physical, cognitive, behavioural and psychological outcomes, and Activities of Daily Living in people living with dementia and MCI.

Searches, using nine databases, were run in November 2021. Two authors carried out study selection/appraisal using the Critical Appraisal Skills Programme checklist. Study characteristics were extracted through the Cochrane handbook for systematic reviews of interventions data extraction form. Data on digital health interventions were extracted through the template for intervention description and replication (TIDieR) checklist and guide. Intervention effectiveness was determined through effect sizes. Meta-analyses were performed to pool data on intervention effectiveness.

Twenty studies were included in the review, with a diverse range of interventions, modes of delivery, activities, duration, length, frequency, and intensity.
