Impurity profiling has a rising importance nowadays due to the increased health problems associated with impurities and degradation products found in several drug substances and formulations. Three advanced, accurate and precise chemometric methods were developed as impurity profiling methods for a mixture of bisoprolol fumarate (BIS) and perindopril arginine (PER) with their degradation products which represent drug impurity or a precursor to such impurity. The methods applied were Partial Least Squares (PLS-1), Multivariate Curve Resolution-Alternating Least Squares (MCR-ALS) and Artificial Neural Networks (ANN). Genetic Algorithm (GA) was used as a variable selection tool to select the most significant wavelengths for the three chemometric models. For proper analysis, a 5-factor 5-level experimental design was used to establish a calibration set of 25 mixtures containing different ratios of the drugs and their degradation products (impurities). The validity of the proposed methods was assessed using an independent validation set. The designed models were able to predict the concentrations of the drugs and the degradation products/impurities in the validation set and pharmaceutical formulation. The proposed methods presented a powerful alternative to traditional and expensive chromatographic methods as impurity profiling tools.Glasses with the formula [80B2O3-4.0La2O3-(16-x) PbO-xNiO, (x ranged from 0.0 to 4.0 mol%)], were produced by the standard quenching method. XRD, SEM and EDAX analysis established the success of the obtained samples preparation. Density measurements and FT-IR analysis confirmed the structural modifications emerging by the entry of Ni2+ ions as a network modifier, where the structural unit's ratio of BO3 (BO4) was affirmed to increase (decrease) with a gradual rise of NBO's number. The semiconducting behavior of the current glassy samples was verified by the role of the structural modifications in decreasing the gap energy and increasing both Urbach and mineralization criterion. Ligand field analysis applied to the absorption spectra exhibited the covalent nature of the Ni2+ bonds. The behavior of electronic polarizability supported the gradual increases of the linear and non-linear refractive index of the samples. These properties qualify the present glasses as an optically active material for the devices operated in the visible-NIR regions.Genetic testing using reverse transcriptase real-time polymerase chain reaction (rRT-PCR) is the mainstay of diagnosis of COVID-19. However, it has not been fully investigated whether infectious viruses are contained in SARS-CoV-2 genome-positive specimens examined using the rRT-PCR test. In this study, we examined the correlation between the threshold Cycle (Ct) value obtained from the rRT-PCR test and virus isolation in cultured cells, using 533 consecutive clinical specimens of COVID-19 patients. The virus was isolated from specimens with a Ct value of less than 30 cycles, and the lower the Ct value, the more efficient the isolation rate. A cytopathic effect due to herpes simplex virus type 1 contamination was observed in one sample with a Ct value of 35 cycles. In a comparison of VeroE6/TMPRSS2 cells and VeroE6 cells used for virus isolation, VeroE6/TMPRSS2 cells isolated the virus 1.7 times more efficiently than VeroE6 cells. There was no significant difference between the two cells in the mean Ct value of the detectable sample. In conclusion, Lower Ct values in the PCR test were associated with higher virus isolation rates, and VeroE6/TMPRSS2 cells were able to isolate viruses more efficiently than VeroE6 cells.
The value of bilateral ureteral reimplant (BUR) at the time of complete primary repair of bladder exstrophy (CPRE) has been suggested, however, outcomes are poorly characterized in current medical literature. We hypothesize that BUR at time of CPRE will decrease the rate of recurrent pyelonephritis, post-operative vesicoureteral reflux (VUR), and the need for subsequent ureteral surgery.
We analyzed 64 consecutive patients with a diagnosis of classic bladder exstrophy (BE) who underwent CPRE at three institutions from 2013 to 2019.15 patients underwent cephalotrigonal BUR-CPRE and 49 patients underwent CPRE alone. Our primary outcome was >1 episode of pyelonephritis as documented in the medical record. Secondary outcomes were persistent vesicoureteral reflux (VUR), with a sub-analysis of number of refluxing renal units and presence of dilating VUR, and the need for subsequent ureteral surgery. Descriptive statistics in addition to standard, two tailed univariate statistics, were used to compare the gro and provides additional detail about need for subsequent ureteral surgeries and increased long term follow-up of these complex patients. Limitations of the study include male predominance of the cohort and lack of randomization of BUR-CPRE.
BUR-CPRE decreases postoperative VUR and the need for additional ureteral surgery in select BE patients; it should be considered when technically feasible. While results continue to suggest a trend toward decreased recurrent pyelonephritis and dilating reflux, further longitudinal follow-up in our cohort will be needed.

The complex and dynamic situation in the current pandemic requires a regionally coordinated and interconnected cooperation between the different stakeholders within the health care system, such as the inpatient sector or the public health service. The aim of this study is to analyze health care management during the COVID-19 pandemic in 2020 with a focus on regional networking and communication structures.
As part of the BMBF-funded project "egePan Unimed", an online questionnaire on pandemic management was sent to the boards of all 35 German university hospitals in November 2020. The questionnaire focused on the core topics of regional networking, crisis management, data exchange, and communication with political stakeholders. The questionnaire consisted of 37 closed and three open-ended questions. After piloting, the invitation to the survey was extended three times by mail and once by telephone.
The results (n=25, response 71.4%) show that 68% of the clinics surveyed were connected to representativesex pandemic care process. There were often structured collaborations with regional clinics and health departments and comparatively few cooperations with the outpatient care sector. However, this cooperation has the potential to prevent overcrowding in hospitals.
To assess changes in self-efficacy and attitudes related to healthy eating and cooking in Cooking Matters for Kids participants.
Prepost study design.
Cooking Matters for Kids programs offered by 35 organizations.
Predominantly third- to fifth-grade children participating in Cooking Matters for Kids lessons during fiscal years 2012-17 with matched presurvey and postsurveys (n = 18,113).
Cooking Matters for Kids consists of six 2-hour experiential nutrition and cooking education lessons.
Self-efficacy related to healthy eating and cooking and attitudes toward healthy foods assessed through the Cooking Matters for Kids Participant Survey.
Changes from the presurvey to postsurvey were assessed using mixed models and repeated measures ordered logistic regression accounting for clustering by course. Effect sizes were calculated using Cohen d for repeated measures. A Bonferroni adjustment was used to correct for multiple comparisons (α = 0.025).
Both overall and individual self-efficacy and attitude scores improved from presurvey to postsurvey (P < 0.0001). The effect sizes were 0.35 for overall self-efficacy score and 0.17 for overall attitude score.
Participation in Cooking Matters for Kids was associated with improvements in self-efficacy and attitudes related to healthy eating and cooking.

This study investigated if the coronavirus disease (COVID-19) pandemic influenced college student food insecurity and factors that might contribute to a student becoming newly food insecure.
A convenience sample was assessed using a cross-sectional survey.
Online.
College students (n = 2,018) enrolled at a land-grant institution in Appalachia.
Food insecurity was assessed using the Hunger Vital Sign with reference before COVID-19 and since COVID-19. Demographic and pandemic-specific questions and their associations with food insecurity status were assessed.
Students were categorized as food secure (food secure before and since COVID-19 or food insecure in the year before COVID-19 but not food insecure since COVID-19), consistently food insecure (food insecure before and since COVID-19), and newly food insecure (food secure before but food insecure since COVID-19). Multivariate logistic regression was used to investigate the relationship between new food insecurity and contributing factors.
Of respondents, 68.4% were food secure, 16.5% were consistently food insecure, and 15.1% were newly food insecure. Loss of employment, increased grocery expenditure, anxiety, and a perceived threat posed by COVID-19 were significant indicators of students being newly food insecure.
More students were facing food insecurity as a result of the COVID-19 pandemic. Continued advocacy for sustainable solutions to college food insecurity is needed.

Specifically-designed community pharmacy-based services represent opportunities to support people with their mental health. As few such services exist worldwide, the Advancing Mental HeaLth Provision In PharmacY (AMPLIPHY) was designed with stakeholders. The purpose was to support people with their mental health when initiated on new prescription or change in drug, dose or quantity of antidepressant, through a series of consultations (up to 3 months).
The aim was to evaluate the feasibility of the AMPLIPHY service. The objectives were to i) pilot the service; ii) examine anonymous consultation data to understand patients' characteristics, priorities and consultation focus and iii) Evaluate pharmacists' experiences.
This service evaluation involved a concurrent mixed methods design. learn more Patient characteristics were extracted from consultation notes and descriptive statistics applied. Content analysis was used to summarise consultation foci and comparisons between patients' priorities with consultation contene service developments.
Pharmacists were motivated to deliver this novel service and some patients were willing to join the service. Analysis of patient demographics, consultation notes and interviews provide insight into the strengths and challenges of the service and provides a blueprint for future service developments.
