RESUMO
BACKGROUND: The projected increase in the prevalence of dementia has sparked interest in understanding the pathophysiology and underlying causal factors in its development and progression. Identifying novel biomarkers in the preclinical or prodromal phase of dementia may be important for predicting early disease risk. Applying metabolomic techniques to prediagnostic samples in prospective studies provides the opportunity to identify potential disease biomarkers. OBJECTIVE: The objective of this systematic review was to summarize the evidence on the associations between metabolite markers and risk of dementia and related dementia subtypes in human studies with a prospective design. DESIGN: We searched PubMed, PsycINFO, and Web of Science databases from inception through December 8, 2023. Thirteen studies (mean/median follow-up years: 2.1-21.0 y) were included in the review. RESULTS: Several metabolites detected in biological samples, including amino acids, fatty acids, acylcarnitines, lipid and lipoprotein variations, hormones, and other related metabolites, were associated with risk of developing dementia. Our systematic review summarized the adjusted associations between metabolites and dementia risk; however, our findings should be interpreted with caution because of the heterogeneity across the included studies and potential sources of bias. Further studies are warranted with well-designed prospective cohort studies that have defined study populations, longer follow-up durations, the inclusion of additional diverse biological samples, standardization of techniques in metabolomics and ascertainment methods for diagnosing dementia, and inclusion of other related dementia subtypes. CONCLUSIONS: This study contributes to the limited systematic reviews on metabolomics and dementia by summarizing the prospective associations between metabolites in prediagnostic biological samples with dementia risk. Our review discovered additional metabolite markers associated with the onset of developing dementia and may help aid in the understanding of dementia etiology. The protocol is registered in the International Prospective Register of Systematic Reviews (PROSPERO) database (https://www.crd.york.ac.uk/prospero/; registration ID: CRD42022357521).

BACKGROUND: Studies investigating the relationship between food insecurity and sleep among older populations are limited. This study aimed to cross-sectionally examine the associations between food sufficiency status and sleep outcomes in a nationally representative sample of older adults. METHODS: Our study included 1,665 older adults (≥ 65 years), using data from the 2013 and 2014 National Health and Aging Trends Study (NHATS). Food insufficiency was determined via participants' experience and utilization of food assistance programs (FAP). Sleep outcomes, including nighttime and total sleep hours, sleep latency, and sleep quality, were derived from self-reported data. Multivariable linear regression and logistic regression models were used to estimate the associations between food sufficiency status and sleep outcomes. RESULTS: In 2013-2014, 86.1% of older adults were classified as food sufficient without FAP, 9.85% as food sufficient with FAP, and 4.08% as food insufficient. Adjusting for sociodemographic characteristics, food sufficient older adults with FAP reported more total sleep hours (ð½ = 0.31, 95% CI: -0.02, 0.64) than those participants who are food sufficient without FAP. Further adjusting for health factors, food sufficient participants with FAP had more nighttime sleep hours and greater total sleep hours compared to those participants food sufficient without FAP. Compared to those deemed as food sufficient without FAP, food sufficient participants with FAP had lower odds of having longer sleep latency (OR = 0.50, 95% CI: 0.28, 0.89), after further adjusting for physical function performance. CONCLUSIONS: Among older adults, food sufficiency with FAP is associated with greater total sleep hours, greater nighttime sleep hours, and lower odds of longer sleep latency. Our findings may help inform nutrition food assistance programs targeting older populations.

OBJECTIVE: The current observational study examined shared decision-making (SDM) with caregivers of Latinx youth within the delivery of multiple evidence-based practices (EBPs) in community mental health services. The aims of the study were to (1) Identify therapist and client factors associated with increased SDM within EBP sessions and (2) Examine the association between SDM and therapeutic alliance between community therapists and Latinx caregivers. METHOD: The Observing Patient Involvement in Decision-Making (OPTION) instrument measured SDM in 210 audio-recorded therapy sessions with 62 community therapists (91.94% female; 69.35% Latinx) and 109 Latinx caregivers (91.43% female) of youth who were an average age of 8.26 years (SD = 3.59). We used the Therapy Process Observational Coding System for Child Psychotherapy-Alliance scale to measure the caregiver-therapist alliance observationally. Multilevel linear regressions were conducted to examine research questions. RESULTS: Greater SDM was observed within sessions where therapists targeted conduct problems versus trauma (B = -8.79, 95% CI[-14.09, -3.49], p = .001). There was a trend that SDM was higher in English-language sessions compared to Spanish. We found that the global measurement of SDM (B = .04, 95% CI[.01, .08], p = .03) and the OPTION item Integrate Preferences (B = .69, 95% CI[.07, 1.32], p = .03) were positively associated with alliance. CONCLUSIONS: SDM may help foster Latinx caregiver engagement within EBP delivery. Provider training in SDM may be warranted with consideration of the specific clinical contexts (e.g., by presenting problem) that are appropriate for collaborative treatment planning. More research is needed to further establish the benefits of SDM in youth psychotherapy.
RESUMO
Pragmatic measures of evidence-based practice (EBP) implementation can support and evaluate implementation efforts. We examined the predictive validity of therapist reports of EBP strategy delivery for children's mental health outcomes. Data were obtained from 1,380 sessions with 248 children delivered by 76 therapists in two county systems. Children (Mage=11.8 years, SD = 3.7) presented with internalizing (52%), externalizing (27%), trauma (16%), and other (5%) concerns. Therapists reported their delivery of EBP strategies on a revised version of the EBP Concordant Care Assessment (ECCA; Brookman-Frazee, et al., Administration and Policy in Mental Health and Mental Health Services Research, 48, 155-170, 2021) that included 25 content (e.g., parenting, cognitive behavioral) and 12 technique strategies (e.g., modeling, practice/role-play). On average, 5.6 ECCA session reports (SD = 2.3) were obtained for each client, and caregivers reported symptoms on the Brief Problem Checklist (Chorpita, et al., Journal of Consulting and Clinical Psychology, 78(4), 526-536, 2010) at baseline, weekly over two months, and again at four months. Multilevel models examined whether the mean extensiveness of each EBP strategy predicted trajectories of child outcomes. More individual technique (6 of 12) than content strategies (1 of 25) were associated with outcome trajectories. For techniques, more extensive use of Performance Feedback and Live Coaching and less extensive use of Addressing Barriers were associated with greater declines in total symptoms, and more extensive use of Establishing/Reviewing Goals, Tracking/Reviewing Progress, and Assigning/Reviewing Homework was associated with declines in externalizing symptoms. For content, more extensive use of Cognitive Restructuring was associated with declines in total symptoms. In addition, higher average extensiveness ratings of the top content strategy across sessions was associated with greater declines in total and externalizing symptoms. Therapist-reported delivery of some EBP strategies showed evidence of predictive validity and may hold utility in indexing quality of care.
RESUMO
PURPOSE: Since Food and Drug Administration approval of collagenase Clostridium histolyticum for Peyronie's disease, there has been significant debate regarding its role and comparable efficacy to surgery. MATERIALS AND METHODS: A randomized, controlled trial was performed of Peyronie's disease men treated with either collagenase C histolyticum + RestoreX penile traction therapy + sildenafil or penile surgery + RestoreX penile traction therapy + sildenafil, with 3-month data presented. Primary objectives were overall satisfaction, subjective changes in erectile function, penile sensation, penile length, and changes in the International Index of Erectile Function-Erectile Function Domain score. Secondary outcomes included objective changes in length, curve, adverse events, and other standardized and nonstandardized questionnaires. RESULTS: A total of 40 men were enrolled, with 38 (collagenase C histolyticum group = 19, surgery group = 19) completing treatment and having 3-month data available. All demographic and clinicopathological variables were similar between groups. Following treatment, 50% of men in the collagenase C histolyticum group reported being very satisfied (vs 21% in the surgery group, P = .08) and noted better subjective erectile function (100% vs 68%, P = .03) and penile length (88% vs 16%, P < .0001), lesser impacts on penile sensation (75% vs 11% no change, P < .001), and similar International Index of Erectile Function-Erectile Function Domain changes (+1.5 vs +2.5, P = .91). Objectively, men in the surgery group had greater curve improvements (84% vs 54%, P < .01) and higher rates of adverse events (50 vs 13 events, P < .001) but decreased penile length (-0.5 cm vs +1.0 cm, P < .01). CONCLUSIONS: At 3 months posttreatment, collagenase C histolyticum + RestoreX penile traction therapy + sildenafil results in lesser curve improvements but greater penile length and fewer adverse events, including impacts on subjective erectile function and sensation, than men treated with surgery.

BACKGROUND: Collagenase Clostridium histolyticum (CCH) has been proven effective in multiple subpopulations of PD men; however, no studies have evaluated its role with congenital penile curvature (CPC). AIM: To evaluate the safety and efficacy of CCH in men with CPC. METHODS: A prospective registry was queried of men undergoing CCH injections at our institution. Beginning in 2016, CCH was administered to CPC men using a similar protocol to PD. A comparative analysis was performed between cohorts to evaluate the safety and efficacy of therapy. OUTCOMES: Objective measures included penile length and curvature, while subjective outcomes included standardized (International Index of Erectile Function and Peyronie's Disease Questionnaire) and non-standardized assessments. Curvature outcomes were categorized as follows: 1 - included all men, with the most recent assessment considered final, and 2 - only men who had completed eight CCH injections or stopped early due to satisfaction. RESULTS: From 2014 to Oct 2021, a total of 453 men (408 PD, 45 CPC) underwent one or more CCH injections. In comparing cohorts, CPC men were younger (33 vs 58 years, p<0.0001), had lesser baseline curvatures (52.5 vs 65°, p<0.01), more ventral curves (25.7 vs 9.2%, p<0.01), and longer penile lengths (12.5 vs 12.0 cm, p=0.04). Following treatment, both cohorts experienced similar curvature improvements. Specifically, PD men experienced 20-25° or 33-35% improvements depending on definition compared to 25-30° or 40-50% in CPC men (all p-values >0.05). CPC and PD men also demonstrated similar changes on standardized questionnaires, with the exception of the Psychological and Physical subdomain, which was more improved in CPC men (-11 vs -4, p<0.01). Baseline curvature was positively correlated with greater absolute (degree) and relative (percent) improvements. Adverse events were similar between groups after controlling for confounders. CLINICAL IMPLICATIONS: CCH may be safely and effectively administered in men with CPC. These data provide the first evidence for the efficacy of a non-surgical therapeutic option in this cohort. STRENGTHS AND LIMITATIONS: Strengths - large, prospective series with standardized assessments; Limitations - non-randomized study, short-term follow-up, and lack of standardized method to differentiate CPC from PD. CONCLUSIONS: CCH may be safely and effectively administered to men with CPC, with similar success rates compared to PD. Increasing curvature was associated with greater absolute (degree) and relative (percent) improvements, supporting the role for CCH in men with mild, moderate, or severe curvatures. External validation is warranted prior to routine implementation.

Flexible synthetic routes to crystalline metal-rich to phosphorus-rich nickel phosphides are highly desired for comparable electrocatalytic HER studies. This report details solvent-free, direct, and tin-flux-assisted synthesis of five different nickel phosphides from NiCl2 and phosphorus at moderate temperatures (500 °C). Direct reactions are thermodynamically driven via PCl3 formation and tuned through reaction stoichiometry to produce crystalline Ni-P materials from metal-rich (Ni2P, Ni5P4) to phosphorus-rich (cubic NiP2) compositions. A tin flux in NiCl2/P reactions allows access to monoclinic NiP2 and NiP3. Intermediates in tin flux reactions were isolated to help identify phosphorus-rich Ni-P formation mechanisms. These crystalline micrometer-sized nickel phosphide powders were affixed to carbon-wax electrodes and investigated as HER electrocatalysts in acidic electrolyte. All nickel phosphides show moderate HER activity in a potential range of -160 to -260 mV to achieve current densities of 10 mA/cm2 ordered as c-NiP2 ≥ Ni5P4 > NiP3 > m-NiP2 > Ni2P, with NiP3 activity showing some particle size influence. Phosphorus-rich c/m-NiP2 appears most stable under acidic conditions during extended reactions. The HER activity of these different nickel phosphides appears influenced by a combination of factors such as particle size, phosphorus content, polyphosphide anions, and surface charge.
RESUMO
Recent surveys of pediatric audiologists have highlighted the need for improved understanding of pediatric loudness perception and their role in the hearing device fitting process. The purpose of this article is to provide a brief overview of methods used to measure loudness perception and summarize the existing literature exploring loudness perception in children. A narrative literature review was conducted and 29 articles were reviewed to (1) provide evidence for or against developmental differences, (2) describe variability across listeners of the same age, and (3) discuss evaluations of test-retest reliability on measures of loudness discomfort levels (LDLs), loudness growth, and loudness balancing. A wide variety of methods have been used to measure loudness perception in children. Results of existing studies point to potential developmental differences in LDLs but relatively consistent growth of loudness across age. Considerable across-child variability of loudness perception suggests that estimating LDLs from hearing thresholds could introduce error into the hearing device fitting/mapping process. Additional areas in need of research include work using loudness balancing measures, improved understanding of how variations in clinical loudness scaling measures could influence measured loudness perception, and examination of the benefit of individually-measured loudness perception during pediatric hearing device fitting.

BACKGROUND: Vegetarian-type dietary patterns have been associated with reducing the risk of developing diabetes and may function as an effective strategy for diabetes management. OBJECTIVES: We aimed to examine the associations between adherence to plant-based diet indices and the risk of developing diabetes in the Boston Puerto Rican Health Study. METHODS: Puerto Rican adults (n = 646), aged 45-75 y and free of diabetes at baseline, were included. Dietary intake was assessed via a validated FFQ. Three plant-based dietary indices were calculated: an overall plant-based diet index (PDI), a healthful plant-based diet index (hPDI), and an unhealthful plant-based diet index (uPDI). Incident diabetes was defined as fasting plasma glucose ≥ 126 mg/dL (7.0 mmol/L), glycated hemoglobin ≥ 6.5% (48 mmol/mol), or use of hypoglycemic agents during follow-up. Cox proportional hazards were used to evaluate associations between the dietary patterns and incidence of diabetes, adjusting for potential confounders, such as age, sex, socioeconomic status, lifestyle factors, obesity, total energy intake, depressive symptomatology, and plasma concentrations of lipids. RESULTS: During a mean of 4.2 y of follow-up, we identified 134 diabetes cases. After adjustment for covariates, higher hPDI was associated with lower risk of developing diabetes (adjusted HR for the highest compared with the lowest tertile: 0.54; 95% CI: 0.31, 0.94; P-trend = 0.03). In contrast, the PDI and uPDI were not significantly associated with the risk of diabetes (P-trend > 0.3 for both). CONCLUSIONS: The healthful plant-based dietary index, but not the total plant-based dietary index, was inversely associated with diabetes risk. These findings suggest that the quality of plant-based diets must be considered when recommending plant-based diets for the prevention of diabetes.This trial was registered at clinicaltrials.gov as NCT01231958.

This study examined the associations between overall diet quality and the risk of dementia in a rural cohort among the oldest old. Included in this prospective cohort study were 2232 participants aged ≥ 80 years and dementia-free at the baseline according to the Geisinger Rural Aging Study (GRAS), a longitudinal cohort in rural Pennsylvania. In 2009, diet quality was assessed by a validated dietary screening tool (DST). Incident cases of dementia during 2009-2021 were identified using diagnosis codes. This approach was validated by a review of electronic health records. Associations between diet quality scores and the incidence of dementia were estimated using the Cox proportional hazards models, adjusted for potential confounders. Across a mean of 6.90 years of follow-up, we identified 408 incident cases of all-cause dementia. Having a higher diet quality was not significantly associated with a lower risk for incidents of all-cause dementia (adjusted HR for the highest compared with the lowest tertile: 1.01, 95% CI: 0.79, 1.29, P-trend = 0.95). Similarly, we did not observe a significant association between diet quality and altered risks of Alzheimer's disease and other forms of dementia. Overall, having a higher diet quality was not significantly associated with a lower risk of dementia among the oldest old during the full follow-up.

PURPOSE: Obtaining a patient's loudness discomfort level (LDL) can assist the audiologist in defining their dynamic range so that the hearing device fitting can ensure that low-level sounds are audible, average-level sounds are comfortable, and more intense sounds are loud but not too loud. A 2016 survey showed that 67.5% of 350 pediatric audiologist reported to never or rarely measure LDLs with pediatric patients. The purpose of this study was to identify factors influencing this previously reported limited use of LDL measures. METHOD: Sixty-two pediatric audiologists in the United States were surveyed using a questionnaire that sought to improve our understanding of the (non)use of loudness perception measures with pediatric patients and to assess familiarity with various loudness perception measurements. In addition, the questionnaire gathered information about the needs of pediatric audiologists in relation to LDL measures. RESULTS: Audiologist report being largely unfamiliar with methods of assessing loudness perception in children, with categorical loudness scaling being the method with which they are most familiar. In addition, audiologists reported being more willing and able to measure LDLs in older compared to younger pediatric patients. Limited use of pediatric loudness perception measures appears to be driven by a lack of familiarity with measurement methods and the belief that loudness perception measures may not be useful for clinical practice. CONCLUSIONS: Findings highlight audiologists' need for further information regarding the relevance of loudness perception measurements with pediatric patients and the need for easy-to-implement LDL measurement procedures for pediatric patients of all ages.

OBJECTIVE: To report outcomes of a novel collagenase clostridium histolyticum (CCH) injection protocol. METHODS: A prospective, sequential database was maintained of all Peyronie's men undergoing CCH injections since 2015. Our protocol has evolved to include changes with injection technique, timing, aggressive modeling/traction, and wrapping. Results of the "traditional" and "novel" techniques were compared using two definitions: "most recent" assessment and final assessments among men who "completed eight (injections) or were satisfied." RESULTS: A total of 509 men underwent greater than or equal to 1 CCH series (traditional, n = 280; novel n = 229). Baseline demographic/clinicopathologic characteristics were similar between groups. Results demonstrated significantly greater curve improvements with the novel technique ("most recent" median 30° vs 20° or 46% vs 28%; "completed eight or satisfied" 34° vs 20° or 58% vs 30%). Using the "completed eight or satisfied" definition, 94% vs 66% of men achieved greater than or equal to 20% improvement (odds ratio 7.6), and 60% vs 24% achieved greater than or equal to 50% improvements (odds ratio 5.0) in the novel cohort (all P < .0001). Importantly, the International Index of Erectile Function Erectile Function Domain score was unchanged, and subjective erectile function (50% vs 5%, P < .0001) and sensation improved (17% vs 8% improved, P = .01) with the new protocol. The novel cohort also reported higher rates of surgery prevention (53% vs 18%), restored/facilitated penetration (57% vs 21%), and hematomas (56% vs 26%), necessitating changes to wrapping procedures (all P < .0001). CONCLUSIONS: Use of the novel CCH protocol results in significant improvements with curvature without negatively impacting erectile function or sensation. Given its specialized nature, it is not recommended for low-volume CCH injectors.

BACKGROUND: Transmission of hepatitis E virus (HEV) within the healthcare setting is extremely rare. Additionally, the development of chronic HEV infection in association with severe acute respiratory syndrome coronavirus disease 2 (SARS-CoV-2) infection and/or its immunomodulatory therapy has not been reported previously. AIMS: To describe the investigation and management of a nosocomial HEV transmission incident during the coronavirus disease 2019 (COVID-19) pandemic. METHODS: Epidemiological and molecular investigation of two individuals hospitalised with COVID-19 who were both diagnosed with HEV infection. RESULTS: Findings from our investigation were consistent with transmission of HEV from one patient with a community-acquired HEV infection to another individual (identical HEV sequences were identified in the two patients), most likely due to a breach in infection control practices whilst both patients shared a bed space on the intensive care unit (ICU). Chronic HEV infection requiring treatment with ribavirin developed in one patient with prolonged lymphopaenia attributable to COVID-19 and/or the immunomodulators received for its treatment. Further investigation did not identify transmission of HEV to any other patients or to healthcare workers. CONCLUSIONS: The extraordinary demands that the COVID-19 pandemic has placed on all aspects of healthcare, particularly within ICU settings, has greatly challenged the ability to consistently maintain optimal infection prevention and control practices. Under the significant pressures of the COVID-19 pandemic a highly unusual nosocomial HEV transmission incident occurred complicated further by progression to a chronic HEV infection in one patient.

BACKGROUND: Studies have found that inappropriate use of non-sterile gloves (NSG) can affect hand hygiene compliance; the main risks are missing opportunities for hand hygiene and gloves being a vector for microbial transmission. AIM: The aims of this study were to explore the accuracy of healthcare worker (HCW) risk assessment and decision making regarding the use of NSG. METHODS: The study was conducted in two acute NHS Trusts and a community social enterprise. A cross-sectional survey was carried out, followed by qualitative semi-structured interviews. FINDINGS: There were highly significant differences at the 95% probability level between staff groups, unqualified staff being significantly more likely than qualified staff to report NSG use when not indicated (P < 0.0001). The primary motivating factor for staff to wear NSG was for personal protection; the secondary factor being the protection of patients. Staff were also motivated by a desire to create an image of professionalism. Respondents were more likely to follow the lead of seniors in their own profession. DISCUSSION: The results suggest a necessity for change interventions aimed at unqualified staff such as healthcare assistants (HCAs). It would be beneficial to review the indications for glove use and amend organisational policies accordingly. Leaders in each professional staff group would be required to influence practice across organisations, taking into account motivating factors, and in association with multi-modal interventions to improve practice.
RESUMO
BACKGROUND: Catheter-associated urinary tract infection (CAUTI) is common in both hospitals and the community. AIM: To investigate the prevalence of indwelling urinary catheters on district nursing caseloads in the UK. METHODS: Participants were recruited through the Infection Prevention Society (IPS). An electronic survey was undertaken on a single day between November 2017 and January 2018. Data were analysed using descriptive statistics. FINDINGS: A total of 49,575 patients were included in the survey, of whom 5352 had an indwelling urinary catheter. This gave a point prevalence of 10.8% (95% confidence interval [CI] = 10.53-11.07), which varied between organisations, ranging from 2.36% (95% CI = 2.05-2.73) to 22.02% (95% CI = 20.12-24.05). Of catheters, 5% were newly placed (within four weeks). Of these, most (77%) had a documented indication for insertion. Only half of patients with a newly placed catheter had a plan for its removal. This varied between organisations in the range of 20%-96%. Only 13% of patients had a patient-held management plan or 'catheter passport' but these patients were significantly more likely to also have an active removal plan (28/36 [78%] vs. 106/231 [46%]; P < 0.0001). Alternative bladder management strategies had been considered for 70/267 (26%) patients. DISCUSSION: The management of patients with an indwelling urinary catheter represents a significant component of district nursing caseloads. Given the high proportion of newly catheterised patients without an active management plan for removal of the catheter, the establishment of an optimal management pathway should be the focus of future prevention efforts.
RESUMO
There is evidence indicating that improvements in infection control practice can reduce the incidence of healthcare-associated infection. This article explores the evidence base for glove use and aseptic technique. There is a lack of evidence regarding the influence of sterile versus clean gloves in clinical care. Therefore in practice, clean and aseptic techniques are often used interchangeably. Nurses must learn to select clean or aseptic technique, and therefore clean or sterile gloves, using a risk assessment protocol. Regular audits of aseptic technique and education are needed to improve care.
