Plain English summary Involving stakeholders in research about dementia care is recognized as an important approach to develop findings that are relevant to individuals living with dementia, family care partners, and health and social professionals in dementia care. Still, this approach is not often used and there is a need for more information about how researchers can engage stakeholders in the research process and the impact of engagement from the perspectives of stakeholders. In this paper, we describe how a mixed group of stakeholders was engaged for a project to identify priorities for dementia care research and their perspectives of the experience. A Stakeholder Advisory Council (SAC) worked together to develop their skills in research and connected with their communities to determine what is most important to be studied in the field of dementia care research. To understand the perspectives of the stakeholders involved in this project, we conducted individual interviews with members of the SAC. This study will help researchers understand how they can collaborate with stakeholders in dementia care and the benefits of including individuals living with dementia, family care partners, and professional stakeholders in the research process.

BackgroundOlder Latino individuals are disproportionally affected by various chronic conditions including impairments in physical and cognitive functions, which are essential for healthy aging and independent living. ObjectiveThis study aimed to evaluate the feasibility and acceptability of FITxOlder, a 12-week mind-body exercise program, in community-dwelling low-income, predominantly older Latino individuals, and assess its preliminary effects on health parameters relevant to healthy aging and independent living. MethodsThis 12-week, single-arm, stage 1B feasibility study had a pre- and poststudy design. A total of 13 older adults (mean age 76.4, SD 7.9 years; 11/13, 85% Latino) of a congregate meal program in a senior center were enrolled. FITxOlder was a tailored Chinese mind-body exercise program using Five Animal Frolics led by a bilingual community health worker (CHW) participating twice a week at the senior center and facilitated by mobile health technology for practice at home, with incrementally increasing goals moving from once a week to at least 3 times a week. The feasibility and acceptability of the study were examined using both quantitative and qualitative data. Healthy aging–related outcomes (eg, physical and cognitive function) were assessed using paired 2-tailed t tests. Qualitative interview data were analyzed using thematic analysis. ResultsThe attendance rate for the 24 exercise sessions was high (22.7/24, 95%), ranging from 93% (1.8/2) to 97% (1.9/2) over the 12 weeks. Participants were compliant with the incremental weekly exercise goals, with 69.2% (9/13) and 75.0% (9/12) meeting the home and program goals in the last 4 weeks, respectively. Approximately 83% (10/12) to 92% (11/12) of the participants provided favorable feedback on survey questions regarding the study and program implementation, such as program content and support, delivery by the CHW, enjoyment and appeal of the Five Animal Frolics, study burden and incentives, and safety concerns. The qualitative interview data revealed that FITxOlder was well accepted; participants reported enjoyment and health benefits and the desire to continue to practice and share it with others. The 5-time sit-to-stand test (mean change at posttest assessment=−1.62; P

Glial cells play an important role in maintaining neuronal homeostasis and may thus influence excitability in epileptogenesis. These cells in the brain have glutamate (Glu) transporters, which remove this neurotransmitter from the extracellular space. Lack of negative (−) feedback makes local neuronal circuits more excitable and potentially contributing to epileptogenic phenomena. In this study, the role of glial cells in providing (−) feedback is shown through different models of brain cells in culture imaged for intracellular calcium concentration [(Ca2+)i]. Moreover, here we study the individual cells by putting them in categories. Neuronal networks with high and low (−) feedback were established by using anti-mitotics to deplete glial cells. Separate stimuli with very low subthreshold concentrations of Glu (250–750 nM) were added to cultures to test if the order of stimulations matter in regard to calcium dynamics outcomes. Additionally, KCl and ATP were used to stimulate glial cells. We found that for cultures high in (−) feedback, order of the stimulus was not important in predicting cellular responses and because of the complexity of networks in low (−) feedback cultures the order of stimulus matters. As an additional method for analysis, comparison of high (−) feedback cultures, and pure astrocytes was also considered. Glial cells in pure astrocyte cultures tend to be larger in size than glial cells in high (−) feedback cultures. The potential effect of (−) feedback at the blood brain barrier (BBB) was also considered for the inflammatory responses of nitric oxide (NO) production and [Ca2+]i regulation using brain microvascular endothelial cells (BMVECs). The inflammatory and calcium signaling pathways both indicate the negative feedback role of astrocytes, poised between the BBB and structures deeper within the brain, where neuronal synapses are homeostatically maintained by glial uptake of neurotransmitters.

Copper high aspect ratio structures (CuHARS) and silver cystine nanoparticles (AgCysNPs) are two unique micro/nano particles under study here that show extensive anti-cancer effects on a glioma tumor cell line. These micro/nano particles have shown potent toxicity in the presence of inflammatory stimulus (combination of tumor necrosis factor, [TNF] and lipo-polysaccharide, LPS). CuHARS with a concentration of 20 μg/ml uniquely increased the catalytic generation of nitric oxide (NO), an important contributor in the immune system. This NO was generated in a cell culture tumor microenvironment (TME) in the presence of 25 µM S-nitrosothiol (cysteine-NO) and the inflammatory stimulus. CuHARS increased the NO production by 68.75% when compared to untreated glioma cells with CysNO and inflammatory stimulus. The production of NO was significantly higher under similar circumstances in the case of normal primary structural cells like brain microvascular endothelial cells (BMVECs). The production of NO by BMVECs went up by 181.25% compared to glioma cells. This significant increase in the NO concentration could have added up to tumorigenesis but the anti-cancer effect of CuHARS was prominent enough to lower down the viability of glioma cells by approximately 20% and increased the metabolism of structural cells, BMVECs by approximately 200%. The immunomodulatory effect of NO in the TME under these circumstances in the presence of the novel micro/nano material, CuHARS has risen up compared to the effect of inflammatory stimulus alone. The potency and specific nature of these materials toward tumor cells may make them suitable candidates for cancer treatment. Successive treatment of CuHARS to glioma cells also proved to be an effective approach considering the decrease in the total count of cells by 11.84 fold in case of three successive treatments compared to a single dose which only decreased the cell count by 2.45 fold showing the dose-dependent increasing toxicity toward glioma cells. AgCysNPs are another potent nanomaterial which also proved its significant toxic nature toward tumor cell lines as demonstrated here, but their immunomodulatory response is still unclear and needs to be explored further.

Neurological disorders that are characterized by unpredictable seizures affect people of all ages. We proposed the use of nanocarriers such as halloysite nanotubes to penetrate the blood–brain barrier and effectively deliver the payload over an extended time period. These 50-nm diameter tubes are a natural biocompatible nanomaterial available in large quantities. We proved a prolonged gradual drug delivery mechanism by the nanotube encapsulating rhodamine isothiocyanate and then ionomycin into brain microvascular endothelial cells (BMVECs). Through delayed diffusion, the nanotubes effectively delivered the drug to the primary BMVECs without killing them, by binding and penetration in time periods of 1 to 24 h.

Abstract Although Kocho is a traditional fermented food widely consumed in Ethiopia, improper fermentation conditions continue to pose a significant challenge. This study aimed to examine the impact of fermentation temperature and duration on kocho quality, utilizing a completely randomized design (CRD). Standard methodologies were employed to evaluate the physicochemical properties, microbial composition, and sensory characteristics of kocho. Data analysis was conducted using Minitab software version 19.2. The fermentation conditions had a significant effect (p

Background: Immunobullous diseases are morphologically heterogeneous and the differentiation between various subtypes is essential for proper treatment and prognosis. Aim of our study was to analyze and correlate clinical, histopathological and immunofluorescence findings in autoimmune bullous diseases. Materials and Methods: A cross-sectional study was done over a period of two years (2010-2012) after approval of the ethics committee. Sixty patients, who met the inclusion criteria of immunobullous disease, were included in the study. Skin biopsy for histopathology and direct immunofluorescence (DIF) examination was taken. DIF using salt-split technique was done in few of the cases. The final diagnosis was based on clinical, histopathology and DIF findings. Pearson′s coefficient of correlation (r) was calculated. Statistical Analysis was done using Epi info version. 7.0. Results: Fifty-three cases with clinical diagnosis of autoimmune bullous diseases were evaluated. In 88.6% of cases, histopathology diagnosis was consistent with clinical diagnosis and in 75.5% of cases, DIF findings were consistent with clinical diagnosis. A positive relation was seen between clinical and DIF findings with r = 0.65 and between histopathology and DIF findings with r = 0.75. DIF positivity was seen in 100% cases of bullous pemphigoid (BP) and pemphigus foliaceous and 94.7% cases of pemphigus vulgaris, which was statistically significant with p < 0.05. In DIF salt-split test, deposition was seen on roof of blister in BP whereas on floor in epidermolysis bullosa acquisita. Conclusion: Our study provides evidence-based guidance for the diagnosis and classification of various immunobullous disorders. DIF test should be done in conjunction with histopathology for definitive diagnosis and to minimize both: False-positive and false-negative results.

The novel synthesis of metal-containing biohybrids using self-assembly methods at physiological temperatures (37 °C) was compared for copper and silver using the amino acid dimer cystine. Once assembled, the copper containing biohybrid is a stable, high-aspect ratio structure, which we call CuHARS. Using the same synthesis conditions, but replacing copper with silver, we have synthesized cystine-capped silver nanoparticles (AgCysNPs), which are shown here to form stable colloid solutions in contrast to the CuHARS, which settle out from a 1 mg/mL solution in 90 min. Both the copper and silver biohybrids, as synthesized, demonstrate very low agglomeration which we have applied for the purpose of applications with cell culture methods, namely, for testing as anti-cancer compounds. AgCysNPs (1000 ng/mL) demonstrated significant toxicity (only 6.8% viability) to glioma and neuroblastoma cells in vitro, with concentrations as low as 20 ng/mL causing some toxicity. In contrast, CuHARS required at least 5 μg/mL. For comparative purposes, silver sulfate at 100 ng/mL decreased viability by 52% and copper sulfate at 100 ng/mL only by 19.5% on glioma cells. Using these methods, the novel materials were tested here as metal−organic biohybrids (MOBs), and it is anticipated that the functionalization and dynamics of MOBs may result in building a foundation of new materials for cellular applications, including cell engineering of both normal and diseased cells and tissue constructs.

This study aimed to evaluate the traditional preparation practices and the proximate, physical, and microbial quality of chuko collected from the Hetosa district in the Arsi zone of Ethiopia. Chuko is a traditional snack food prepared from roasted barley flour, spice powders, and traditional ghees. In this study, 30 respondents from the Hetosa district were selected to assess the chuko preparation practices and cultural aspects of the chuko. Furthermore, 25 chuko samples were collected to determine physicochemical, proximate, and microbial quality. From the survey results, it is understood that chuko was mainly prepared for household consumption on special occasions, such as weddings, food for postnatal women, food in blessing ceremonies, food on holidays, and visiting relatives. The average moisture and ash contents of the collected chuko samples were observed as 2.52 ± 0.64% and 1.77 ± 68%, respectively. The mean fat, protein, fiber, and carbohydrate contents of the collected chuko samples were as 42.02 ± 9.89%, 5.82 ± 0.88%, 1.89 ± 0.72% & 45.98 ± 8.33%, respectively. The mean pH, water activity, and textural profile of the collected chuko were 5.11 ± 0.21, 0.22 ± 0.05 N, respectively. The total aerobic plate counts of the chuko samples ranged from 1.15 × 103 to 1.26 × 105 cfu/g, and the average coliform and yeast growth were 1.70 × 102 cfu/g and 4.90 × 101 cfu/g, respectively. This study concluded that Chuko preparation and consumption were traditionally performed. Chuko is a traditional low-moisture, high-fat, high-energy food product with a shelf life of one year. Furthermore, the value addition of Chuko, product diversification, and promotion of indigenous knowledge are recommended for future work.

Introduction: Earlier considered a rare disease, childhood herpes zoster is showing an increasing incidence. This study was con- ducted to study the clinical features of herpes zoster (HZ) in chil- dren below 12 years of age along with immune suppression status. Materials and Methods: The study was carried out in the Depart- ment of Dermatology at a Tertiary Care Centre in Gujarat for 4 years. Children aged ≤12 years with a diagnosis of HZ were en- rolled in a predesigned pro forma. Diagnosis was mainly clinical with use of Tzanck smears in difficult cases. ELISA for HIV was done in all cases. Results: Total of 51 children aged ≤12 years were enrolled in the study. Male predominance was seen. The mean age was 8.74 years. 72.5% patients had localized dermatomal involvement and dis- semination was not seen. Majority of patients (51%) did not have any preceding symptoms. Prior exposure to varicella was present in only 19 (37.3%) cases. Evidence of immunosuppression on his- tory, clinical examination, and investigations was present in 11(21.5%). Conclusion: Although childhood HZ is increasing, atypical pres- entations and dissemination are rare. Immunosuppression does not play a major role in these patients. We conclude that HZ in children follows a relatively benign course as compared to adults.

To determine the contribution of injectable iron administered to hemodialysis (HD) patients in causing oxidative stress and the beneficial effect of N-acetylcysteine (NAC) in re-ducing it, we studied in a prospective, double blinded, randomized controlled, cross over trial 14 adult HD patients who were randomized into two groups; one group received NAC in a dose of 600 mgs twice daily for 10 days prior to intravenous iron therapy and the other group received placebo. Both the groups were subjected to intravenous iron therapy, 100 mg of iron sucrose in 100 mL of normal saline given over a period of one hour. Blood samples for the markers of oxidative stress were taken before and after iron therapy. After the allowance of a week of wash out period for the effect of N-acetylcysteine we crossed over the patients to the opposite regimen. We measured the lipid peroxidation marker, malondiaaldehyde (MDA), to evaluate the oxidative stress and total anti-oxidant capacity (TAC) for the antioxidant level in addition to the highly sensitive C-reactive protein (HsCRP). Non-invasive assessment of endothelial dysfunction was measured by digital plethysmography before and after intravenous iron therapy. There was an increase of MDA (21.97 + 3.65% vs 7.06 + 3.65%) and highly sensitive C-reactive protein (HsCRP) (11.19 + 24.63% vs 13.19 + 7.7%) after iron administration both in the placebo and the NAC groups. NAC reduced the baseline acute systemic generation of oxidative stress when com-pared to placebo, which was statistically significant with MDA (12.76 + 4.4% vs 9.37 + 4.40%: P = 0.032) but not with HsCRP though there was a declining trend (2.85 + 22.75 % vs 8.93 + 5.19%: P = 0.112). Pre-treatment with NAC reduced the endothelial dysfunction when compared to placebo, but it was not statistically significant, except for reflection index (RI). We conclude that in our HD patients NAC reduced the oxidative stress before and after the administration of intravenous iron therapy in addition to the endothelial dysfunction induced by this treatment.

Background: COVID-19 screening testing (ST) can detect asymptomatic or pre-symptomatic cases, allowing for prompt identification of cases and close contacts. This study examined parents' and school staffs' knowledge and attitudes toward to a pilot school-based ST program in a school district in southern Arizona. Methods: In May 2021, online surveys to parents and school staff were administered to examine attitudes toward ST and impacts of the COVID-19 pandemic. Unweighted percent estimates were calculated, and bivariate differences were examined by demographics. Associations were assessed using chi-square tests and logistic regression. Results: The survey had response rates of 10% (606/6085) and 22% (187/849) among parents and staff, respectively. Approximately one-third of responding parents (35%) would or already allow their child to participate in school-based ST, 37% would not participate; 28% were unsure. Among responding staff, 46% would or already participate in ST, 33% would not; 21% were unsure. The top concern (38%) among responding staff was taking job-related leave if testing positive. Conclusion: Schools work to balance the needs of students, families, and staff by implementing supportive and flexible policies and practices founded on buy-in and acceptance from their communities.
