Understanding the Perspectives and Needs of Latinx Caregivers of Persons with Alzheimer's Disease in the Appalachians: An Interpretive Phenomenological Approach.

Background: Alzheimer's disease and related dementias (ADRD) disproportionately impact Latinx and other communities of color in the United States. The challenges for patients with ADRD and their informal caretakers can be attributed, in part, to the gaps that exist within health care services and systems. Objective: To understand the perspectives of barriers, beliefs, knowledge, and needs for the Latinx informal caregivers that take care of relatives with ADRD in the Upstate of South Carolina, region of Appalachia. Methods: This study was approved by the GHS-Prisma Health and Clemson University IRB, Study #Pro00086707. In-depth phone interviews were conducted with a sample of Latinx informal caregivers. A descriptive and interpretive phenomenological approach was used for analysis. Participants were recruited through community partnerships with local organizations. Results: Salient themes identified in this study included the relevance of caregiver's degree of awareness about the disease and a perspective of Alzheimer's disease as a progressive and degenerative disease. Critical moments identified encompassed challenges related to patient engagement with the outside world, their attitudes, and behaviors, as well as caregiver-related challenges with access to culturally and linguistically relevant resources needed to provide proper care. Caregivers identified several culturally relevant coping strategies used and motivators in providing care for their relatives with ADRD. Conclusions: Linguistically and culturally sensitive programs and resources that account for knowledge, assets, and needs of Latinx informal caregivers of ADRD patients are needed to improve the quality of care and decrease disparities in health outcomes for Latinx older adults.

Weight Loss Is a Strong Predictor of Memory Disorder Independent of Genetic Influences.

BACKGROUND: Past studies identified a link between weight loss and dementia, but lacked consistent conclusions. We sought to establish this link by examining the weight change profiles before and after dementia diagnosis. METHODS: Using data from the Health and Retirement Study (1996-2020), we examined 13,123 participants. We conducted a nested case-control analysis to assess differences in biennial weight change profile while controlling for BMI, longevity polygenic risk scores, and APOE gene variants. RESULTS: Participants with a memory disorder lost weight (-0.63%) biennially, whereas those without a diagnosis did not (+0.013%, p-value < 0.0001). Our case-control study shows a significant difference (p-value < 0.01) in pre-dementia % weight changes between the cases (-0.29%) and controls (0.19%), but not in post-dementia weight changes. The weight loss group have the highest risk (OR = 2.01; p-value < 0.0001) of developing a memory disorder compared to the stable weight and weight gain groups. The observations hold true after adjusting for BMI, longevity polygenic risk scores, and APOE variant in a multivariable model. CONCLUSIONS: We observe that weight loss in dementia is a physiological process independent of genetic factors associated with BMI and longevity. Pre-dementia weight loss may be an important prognostic criterion to assess a person's risk of developing a memory disorder.

Exploring Constraints to Well-Being for Older Adults in Transition Into an Assisted Living Home: A Qualitative Study.

Transitions into an assisted living home (ALH) are difficult and may impact the well-being of older adults. A thematic analysis guided by grounded theory was employed to better understand how a transition into an ALH influenced older adults' overall well-being. Individual, face-to-face interviews were conducted with a convenience sample of 14 participants at an ALH in the rural, southeastern U.S. Two central findings that influenced well-being during the transition process were revealed: loss of independence (sub-themes include loss of physical and mental health and loss of driving) and downsizing in space and possessions. The themes support and broaden the Hierarchical Leisure Constraints Theory, a Modified Constraints to Wellbeing model is proposed, and implications for older adult health care practitioners in ALHs are recommended. Further research is needed on the Modified Constraints to Wellbeing model and how to better describe these constraints to older adults' well-being when relocating into ALHs.

Genetic Factors That Contribute to Antibiotic Resistance through Intrinsic and Acquired Bacterial Genes in Urinary Tract Infections.

The overprescribing and misuse of antibiotics have led to the rapid development of multidrug-resistant bacteria, such as those that cause UTIs. UTIs are the most common outpatient infections and are mainly caused by Escherichia coli and Klebsiella spp., although some Gram-positive bacteria, such as Pseudomonas aeruginosa, have been isolated in many cases. The rise of antimicrobial-resistant bacteria is a major public health concern, as it is predicted to lead to increased healthcare costs and poor patient outcomes and is expected to be the leading cause of global mortality by 2050. Antibiotic resistance among bacterial species can arise from a myriad of factors, including intrinsic and acquired resistance mechanisms, as well as mobile genetic elements, such as transposons, integrons, and plasmids. Plasmid-mediated resistance is of major concern as drug-resistance genes can quickly and efficiently spread across bacterial species via horizontal gene transfer. The emergence of extended-spectrum ß-lactamases (ESBLs) such as NDM-1, OXA, KPC, and CTX-M family members has conferred resistance to many commonly used antibiotics in the treatment of UTIs, including penicillins, carbapenems, cephalosporins, and sulfamethoxazole. This review will focus on plasmid-mediated bacterial genes, especially those that encode ESBLs, and how they contribute to antibiotic resistance. Early clinical detection of these genes in patient samples will provide better treatment options and reduce the threat of antibiotic resistance.

TOMM40 genetic variants associated with healthy aging and longevity: a systematic review.

INTRODUCTION: Healthy aging relies on mitochondrial functioning because this organelle provides energy and diminishes oxidative stress. Single nucleotide polymorphisms (SNPs) in TOMM40, a critical gene that produces the outer membrane protein TOM40 of mitochondria, have been associated with mitochondrial dysfunction and neurodegenerative processes. Yet it is not clear whether or how the mitochondria may impact human longevity. We conducted this review to ascertain which SNPs have been associated with markers of healthy aging. METHODS: Using the PRISMA methodology, we conducted a systematic review on PubMed and Embase databases to identify associations between TOMM40 SNPs and measures of longevity and healthy aging. RESULTS: Twenty-four articles were selected. The TOMM40 SNPs rs2075650 and rs10524523 were the two most commonly identified and studied SNPs associated with longevity. The outcomes associated with the TOMM40 SNPs were changes in BMI, brain integrity, cognitive functions, altered inflammatory network, vulnerability to vascular risk factors, and longevity. DISCUSSIONS: Our systematic review identified multiple TOMM40 SNPs potentially associated with healthy aging. Additional research can help to understand mechanisms in aging, including resilience, prevention of disease, and adaptation to the environment.

Navigating through incontinence: A qualitative systematic review and meta-aggregation of the experiences of family caregivers.

BACKGROUND: Community dwelling older adults who are care dependent are highly affected by incontinence, resulting in substantial informal caregiver burden. Understanding the experiences of these caregivers is needed to develop supportive programs that reduce caregiver burden and rates of institutionalization for care recipients. OBJECTIVES: This systematic review aimed to critically appraise and synthesize the qualitative literature on the perceptions, experiences, and consequences of informal caregivers managing incontinence in community dwelling older adults. DESIGN: A qualitative evidence synthesis using meta-aggregation. DATA SOURCES: CINAHL, Embase, Ovid Medline, PsycInfo, Scopus, and ProQuest Dissertations and Theses. REVIEW METHODS: A comprehensive search was conducted to identify qualitative studies of all designs, published in English from January 1970 to November 2020, reporting on the experiences of unpaid adult family members or friends providing care at home to an adult aged 60 or older with urinary and/or fecal incontinence. Screening, data extraction, and quality appraisal were conducted independently by two reviewers, with disagreements resolved by consensus with all team members. Joanna Briggs Institute (JBI) processes were used to assess study quality, and the dependability and credibility of both study findings and synthesized findings. All articles included met predetermined criteria. RESULTS: Database searches yielded 1165 references, of which 117 full-text documents were screened. Seven articles of moderate to high methodological quality met eligibility criteria and were included. Studies occurred in nine countries with 134 participants who were mostly female spouses of the care recipient. From these eligible studies, 49 findings were extracted with 35 equivocal or credible findings eligible for meta-aggregation. Findings were synthesized into the following four categories: 1) emotional responses, 2) physical, financial, and social consequences, 3) family roles and caregiver support, and 4) management and coping strategies. CONCLUSIONS: Informal caregivers experience many physical, psychosocial, and financial challenges in caring for an older family member with incontinence. Educational and supportive programs for managing incontinence should be multi-component and tailored to meet the individual needs of informal caregivers. Future research should incorporate strategies to cope with emotional responses and offer practical strategies for managing incontinence. PROSPERO REGISTRATION: CRD42017069185.

Burdens and Educational Needs of Informal Caregivers of Older Adults With Urinary Incontinence: An Internet-Based Study.

PURPOSE: The purpose of this study was to describe the burden and educational needs of informal caregivers of care-dependent older adults with urinary incontinence (UI). DESIGN: A cross-sectional, descriptive survey of informal caregivers recruited through Google Ads was performed. METHODS: An online survey, including the Overactive Bladder-Family Impact Measure, was used to assess five areas of the experience of the informal caregiver that may be affected by caring for a person with UI and their educational needs. FINDINGS: Respondents (n = 77) reported a substantial impact of their care recipients' UI on their lives, with concern, travel, and social subscales most affected. However, 42% never sought treatment on behalf of their care recipient. Educational needs included UI treatment strategies and guidance to select appropriate supplies. CONCLUSIONS: Caregivers underreported their care recipient's UI and need substantially more support from healthcare providers to manage the condition. CLINICAL RELEVANCE: Nurses should assess for UI among care-dependent older adults and, if present, provide information and strategies to lessen the impact on caregiver lives.

Trends in Poor Health Indicators Among Black and Hispanic Middle-aged and Older Adults in the United States, 1999-2018.

Importance: Adults who belong to racial/ethnic minority groups are more likely than White adults to receive a diagnosis of chronic disease in the United States. Objective: To evaluate which health indicators have improved or become worse among Black and Hispanic middle-aged and older adults since the Minority Health and Health Disparities Research and Education Act of 2000. Design, Setting, and Participants: In this repeated cross-sectional study, a total of 4 856 326 records were extracted from the Behavioral Risk Factor Surveillance System from January 1999 through December 2018 of persons who self-identified as Black (non-Hispanic), Hispanic (non-White), or White and who were 45 years or older. Exposure: The 1999 legislation to reduce racial/ethnic health disparities. Main Outcomes and Measures: Poor health indicators and disparities including major chronic diseases, physical inactivity, uninsured status, and overall poor health. Results: Among the 4 856 326 participants (2 958 041 [60.9%] women; mean [SD] age, 60.4 [11.8] years), Black adults showed an overall decrease indicating improvement in uninsured status (ß = -0.40%; P < .001) and physical inactivity (ß = -0.29%; P < .001), while they showed an overall increase indicating deterioration in hypertension (ß = 0.88%; P < .001), diabetes (ß = 0.52%; P < .001), asthma (ß = 0.25%; P < .001), and stroke (ß = 0.15%; P < .001) during the last 20 years. The Black-White gap (ie, the change in ß between groups) showed improvement (2 trend lines converging) in uninsured status (-0.20%; P < .001) and physical inactivity (-0.29%; P < .001), while the Black-White gap worsened (2 trend lines diverging) in diabetes (0.14%; P < .001), hypertension (0.15%; P < .001), coronary heart disease (0.07%; P < .001), stroke (0.07%; P < .001), and asthma (0.11%; P < .001). Hispanic adults showed improvement in physical inactivity (ß = -0.28%; P = .02) and perceived poor health (ß = -0.22%; P = .001), while they showed overall deterioration in hypertension (ß = 0.79%; P < .001) and diabetes (ß = 0.50%; P < .001). The Hispanic-White gap showed improvement in coronary heart disease (-0.15%; P < .001), stroke (-0.04%; P < .001), kidney disease (-0.06%; P < .001), asthma (-0.06%; P = .02), arthritis (-0.26%; P < .001), depression (-0.23%; P < .001), and physical inactivity (-0.10%; P = .001), while the Hispanic-White gap worsened in diabetes (0.15%; P < .001), hypertension (0.05%; P = .03), and uninsured status (0.09%; P < .001). Conclusions and Relevance: This study suggests that Black-White disparities increased in diabetes, hypertension, and asthma, while Hispanic-White disparities remained in diabetes, hypertension, and uninsured status.

Feasibility of Tele-Prompt: A tablet-based prompted voiding intervention to support informal caregivers of older adults with urinary incontinence.

Urinary incontinence (UI) is a highly prevalent condition, burdening older adults and their informal caregivers. This study explored the development and feasibility of a 6-week evidence-based, educational/skill building program delivered via tablet-personal computer aimed at developing informal caregiver UI knowledge; and enhancing informal caregiver skill set in prompted voiding and toileting strategies. Caregivers also received individualized weekly coaching sessions from a nurse expert. Feasibility and preliminary efficacy were tested in three caregiver/care-recipient dyads. Recruitment of eligible participants through community-based resources was a challenge to feasibility. Most caregivers found the technology acceptable, but adherence to prompted voiding was inconsistent. All caregivers rated the intervention highly, reported improvements in their care-recipient's urine leakage, found access to a UI expert beneficial, and would recommend it to a friend. The results suggest that the tablet-facilitated intervention was feasible and acceptable to informal caregivers and showed promise for improving both caregiver and care recipient outcomes.

De- and repolarization mechanism of flagellar morphogenesis during a bacterial cell cycle.

Eukaryotic morphogenesis is seeded with the establishment and subsequent amplification of polarity cues at key times during the cell cycle, often using (cyclic) nucleotide signals. We discovered that flagellum de- and repolarization in the model prokaryote Caulobacter crescentus is precisely orchestrated through at least three spatiotemporal mechanisms integrated at TipF. We show that TipF is a cell cycle-regulated receptor for the second messenger--bis-(3'-5')-cyclic dimeric guanosine monophosphate (c-di-GMP)--that perceives and transduces this signal through the degenerate c-di-GMP phosphodiesterase (EAL) domain to nucleate polar flagellum biogenesis. Once c-di-GMP levels rise at the G1 → S transition, TipF is activated, stabilized, and polarized, enabling the recruitment of downstream effectors, including flagellar switch proteins and the PflI positioning factor, at a preselected pole harboring the TipN landmark. These c-di-GMP-dependent events are coordinated with the onset of tipF transcription in early S phase and together enable the correct establishment and robust amplification of TipF-dependent polarization early in the cell cycle. Importantly, these mechanisms also govern the timely removal of TipF at cell division coincident with the drop in c-di-GMP levels, thereby resetting the flagellar polarization state in the next cell cycle after a preprogrammed period during which motility must be suspended.

Caffeine intake and its association with urinary incontinence in United States men: results from National Health and Nutrition Examination Surveys 2005-2006 and 2007-2008.

PURPOSE: Epidemiological studies in women have revealed an association between caffeine intake and urinary incontinence, although evidence among men is limited. Therefore, we evaluated the association between caffeine intake and urinary incontinence in United States men. MATERIALS AND METHODS: Data were used from male NHANES (National Health and Nutrition Examination Surveys) 2005-2006 and 2007-2008 participants. Urinary incontinence was defined using a standard questionnaire with Incontinence Severity Index scores 3 or greater categorized as moderate to severe. Structured dietary recall was used to determine caffeine consumption (mg per day), water intake (gm per day) and total dietary moisture (gm per day). Stepwise multivariable logistic regression models were used to assess the association between caffeine intake at or above the 75th and 90th percentiles and moderate to severe urinary incontinence, controlling for potential confounders, urinary incontinence risk factors and prostate conditions in men age 40 years or older. RESULTS: Of the 5,297 men 3,960 (75%) were 20 years old or older with complete data. Among these men the prevalence of any urinary incontinence was 12.9% and moderate to severe urinary incontinence was 4.4%. Mean caffeine intake was 169 mg per day. Caffeine intake at the upper 75th percentile (234 mg or more daily) and 90th percentile (392 mg or more per day) was significantly associated with having moderate to severe urinary incontinence (1.72, 95% 1.18-2.49 and 2.08, 95% 1.15-3.77, respectively). In addition, after adjusting for prostate conditions, the effect size for the association between caffeine intake and moderate to severe urinary incontinence remained. CONCLUSIONS: Caffeine consumption equivalent to approximately 2 cups of coffee daily (250 mg) is significantly associated with moderate to severe urinary incontinence in United States men. Our findings support the further study of caffeine modification in men with urinary incontinence.

Supportive approaches for Alzheimer disease.

Alzheimer disease (AD) accounts for most dementia diagnoses. Acetylcholinesterase inhibitors and antipsychotics are first-line drug therapies for cognitive decline and to manage neuropsychiatric symptoms, respectively. Because AD is relentlessly progressive, NPs will need to provide long-term support to patients and their caregivers.

Probing flagellar promoter occupancy in wild-type and mutant Caulobacter crescentus by chromatin immunoprecipitation.

In the asymmetric predivisional cell of Caulobacter crescentus, TipF and TipN mark the cellular pole for future flagellar development. TipF is essential for motility and contains a cyclic-di-GMP phosphodiesterase-like (EAL) domain that is necessary for proper function. TipN is localized to the flagellar pole before TipF and is essential for the proper placement of the flagellum in C. crescentus. Using ß-galactosidase promoter-probe assays and quantitative chromatin immunoprecipitation, we investigated the influence of the C. crescentus flagellar assembly regulator TipF on flagellar gene transcription. We compared the transcriptional activity of class II-fliF-lacZ, class III-flgE-lacZ, and class IV-fljL-lacZ fusions in a ΔtipF mutant with that of other flagellar mutants and the wild-type strain. We subsequently verified the in vivo occupancy of the fliF, flgE, and fljL flagellar promoters by the flagellar regulators CtrA, FlbD, and FliX in addition to RNA polymerase. We deduce that TipF contributes to proper expression of flagellar genes in C. crescentus by acting both within and outside of the canonical flagellar gene expression hierarchy.
