Effectiveness of physical rehabilitation on physical functioning and quality of life for long-term care residents with dementia: a systematic review and meta-analysis.

OBJECTIVE: The objective of this review was to evaluate the effectiveness of physical rehabilitation versus non-rehabilitation comparators on physical functioning and quality of life for long-term care (LTC) residents with dementia. INTRODUCTION: LTC residents living with dementia often have impaired physical functioning and quality of life. Physical rehabilitation can improve physical functioning and quality of life for individuals living with dementia; however, many LTC residents with dementia do not receive physical rehabilitation and providers are unsure what interventions to employ. A synthesis of studies examining physical rehabilitation will help guide practice in the LTC sector where most residents live with dementia. Previous syntheses have focused on all residents in LTC, specific professions, interventions, or people with dementia in the community. Our review focuses on LTC residents with dementia and a broader definition of physical rehabilitation. INCLUSION CRITERIA: This review includes studies that evaluate physical rehabilitation in comparison with non-rehabilitation controls among LTC residents with any severity of dementia. We included studies that measure the effect on activities of daily living, performance-based physical functioning, and self- or proxy-rated quality of life. METHODS: Searches were conducted in APA PsycINFO (EBSCOhost), CINAHL (EBSCOhost), PubMed (National Library of Medicine), Embase, Scopus, and the Cochrane CENTRAL database with no date or language limitations. Two independent reviews assessed the studies against the inclusion criteria. Two independent reviewers extracted data and conducted a quality assessment using a structured extraction form. Certainty of evidence was ascertained using the Grading of Recommendations, Assessment, Development and Evaluation (GRADE) approach. Where possible, studies were pooled in meta-analyses; otherwise, a narrative synthesis was performed. RESULTS: Thirty-three studies were included (n = 3072 participants); 27 were randomized control trials and the remaining 6 were non-randomized trials. The overall risk of bias of the included studies was low to unclear. Many of the included studies focused on increasing activity or walking, while few were individually tailored or at an intensity appropriate to induce therapeutic effects on physical function. Physical function was also measured via several outcome measures, limiting our ability to pool results. There was low certainty evidence that physical rehabilitation improved activities of daily living (12 RCTs, 1348 participants, SMD 0.78; 95% CI 0.27 to 1.30) and the Short Physical Performance Battery Score (3 RCTs, 258 participants, MD 3.01 points; 95% CI 1.37 to 4.66) compared with non-rehabilitation interventions. There was low to moderate certainty evidence that physical rehabilitation demonstrated no change in the 30-Second Sit to Stand Test (2 RCTs, 293 participants, MD 0.79 repetitions; 95% CI -0.45 to 2.03), 6-Minute Walk Test (4 RCTs, 363 participants, MD 17.32 meters; 95% CI -29.41 to 64.05), gait speed (4 RCTs, 400 participants, MD 0.10 meters/seconds; 95% CI -0.02 to 0.22), Timed Up and Go Test (3 studies, 275 participants, MD -2.89 seconds; 95% CI -6.62 to 0.84), or quality of life (4 RCTs, 419 participants, SMD 0.20; 95% CI -0.08 to 0.47). CONCLUSIONS: This review demonstrates that physical rehabilitation may improve activities of daily living for LTC residents living with dementia, though the evidence is of low certainty. The effect of physical rehabilitation on specific functional tasks, like gait speed and quality of life, are less clear. Future research should examine the effects of individualized, progressive interventions on outcome measures that reflect the capacity and preferences of LTC residents with more advanced dementia.

Effectiveness of physical rehabilitation in improving physical functioning and quality of life for long-term-care residents with dementia: a systematic review protocol.

OBJECTIVE: The objective of this review is to evaluate the effectiveness of physical rehabilitation versus non-rehabilitation control in improving physical functioning and quality of life in long-term care residents with dementia. INTRODUCTION: Many long-term-care residents live with dementia and have impaired physical function and poor quality of life. Physical rehabilitation can improve physical function and quality of life for people living with dementia, yet many long-term-care residents with dementia do not receive this intervention, and health care providers are unsure of which rehabilitation interventions are effective. Studies synthesizing effective rehabilitation programs are needed to guide practice in the long-term-care sector where many residents live with dementia. Previous studies have focused broadly on long-term care, specific professions, interventions or outcomes, or people with dementia in the community. Our review will focus on long-term-care residents living with dementia and a broader definition of physical rehabilitation. INCLUSION CRITERIA: This review will include studies that evaluate physical rehabilitation in comparison with non-rehabilitation controls among long-term-care residents with any severity of dementia. We will include studies that measure the effect on performance-based physical functioning and self- or proxy-reported quality of life. METHODS: Searches will be conducted in APA PsycINFO (EBSCO), CINAHL (EBSCO), MEDLINE (Ovid), Embase, Scopus, and the Cochrane CENTRAL database with no date or language limitations. Two independent reviewers will conduct a critical appraisal of eligible studies, assess methodological quality, and extract the data. Where possible, studies will be pooled in a statistical meta-analysis. SYSTEMATIC REVIEW REGISTRATION NUMBER: PROSPERO CRD42022308444.

Secondary osteon variants and remodeling in human bone.

Histomorphometric analysis of human cortical bone has documented the occurrence of secondary osteon variants. These include drifting osteons which form tails as they move erratically through the cortex and Type II osteons which show partial resorption and redeposition within the cement line of the osteon. Little is known about the biological significance of these variants. Prior studies suggested correlations with age, biomechanics, diet, and mineral homeostasis. No study has yet tested for osteon variant associations with static measures of bone remodeling. In this study, thin sections (n = 112) of the posterior femur representing a late English Medieval adult human osteological collection, subdivided by age, sex, and socio-economic status, were examined to determine whether remodeling indicators reconstructed from osteon parameters (area, diameter, area ratios) and densities differed between categories of presence or absence of Type II and drifting osteon variants. Of the 112 sections, 33 presented with Type II osteons, and 38 had drifting osteons. Sporadic statistically significant results were identified. Haversian canal:osteon area ratio differed (p = 0.017) with Type II osteon presence, Type II osteons were more prevalent in males than females (p = 0.048), and drifting osteons were associated with smaller osteon (p = 0.049) and Haversian canal area (p = 0.05). These results may be explained through some biological (sex) and social (status) processes such as a period of physiological recovery (e.g., following lactation, malnutrition). However, the general lack of consistent relationships between osteon variants and remodeling indicators suggests they occur as a result of natural variation.

Position effects on promoter activity in Escherichia coli and their consequences for antibiotic-resistance determinants.

The activity of any bacterial promoter is generally supposed to be set by its base sequence and the different transcription factors that bind in the local vicinity. Here, we review recent data indicating that the activity of the Escherichia coli lac operon promoter also depends upon its chromosomal location. Factors that affect promoter activity include the binding of nucleoid-associated proteins to neighbouring sequences, supercoiling and the activity of neighbouring promoters. We suggest that many bacterial promoters might be susceptible to similar position-dependent effects and we review recent data showing that the expression of mobile genes encoding antibiotic-resistance determinants is also location-dependent, both when carried on a bacterial chromosome or a conjugative plasmid.

Aboriginal Australian mitochondrial genome variation - an increased understanding of population antiquity and diversity.

Aboriginal Australians represent one of the oldest continuous cultures outside Africa, with evidence indicating that their ancestors arrived in the ancient landmass of Sahul (present-day New Guinea and Australia) ~55 thousand years ago. Genetic studies, though limited, have demonstrated both the uniqueness and antiquity of Aboriginal Australian genomes. We have further resolved known Aboriginal Australian mitochondrial haplogroups and discovered novel indigenous lineages by sequencing the mitogenomes of 127 contemporary Aboriginal Australians. In particular, the more common haplogroups observed in our dataset included M42a, M42c, S, P5 and P12, followed by rarer haplogroups M15, M16, N13, O, P3, P6 and P8. We propose some major phylogenetic rearrangements, such as in haplogroup P where we delinked P4a and P4b and redefined them as P4 (New Guinean) and P11 (Australian), respectively. Haplogroup P2b was identified as a novel clade potentially restricted to Torres Strait Islanders. Nearly all Aboriginal Australian mitochondrial haplogroups detected appear to be ancient, with no evidence of later introgression during the Holocene. Our findings greatly increase knowledge about the geographic distribution and phylogenetic structure of mitochondrial lineages that have survived in contemporary descendants of Australia's first settlers.

Using mixed methods for evaluating an integrative approach to cancer care: a case study.

OBJECTIVE: To evaluate the impact of participating in an integrative cancer care program at the Centre for Integrated Healing in Vancouver, British Columbia, on patients' lifestyle, quality of life, and overall well-being. STUDY DESIGN: A mixed-methods case study with a pre- and posttest design. No control group was utilized. METHODS: All new patients starting at the Centre for Integrated Healing between May and September of 2004 were invited to join the study. Forty-six of 77 new patients agreed to participate. Quantitative data measuring quality of life, social support, anxiety and depression, locus of control, and hope were assessed at baseline (pre-program start) and at 6 weeks and 5 months from the start of the program. Qualitative data in the form of focus groups and interviews were collected midway through the follow-up period to further explore program impacts. RESULTS: No statistically significant improvements or declines were noted on the quantitative measures between baseline and the 5-month follow-up point. The qualitative findings revealed a theme of patients' active engagement in their cancer care involving empowered decision making and creating personal change. Facilitators of active patient engagement in their own care from the integrative program included healing partnerships with practitioners, information and resources, managing the integration of complementary and conventional therapies, emotional support, and a sense of hope. DISCUSSION: This case study was a first attempt at documenting the impact of an integrative cancer care program at the Centre for Integrated Healing. Study limitations included a small sample size, which limited power to detect quantitative changes on the questionnaires and a lack of a control group. Qualitative findings indicated that patients found value in the "person-oriented" holistic approach to care, which encouraged patients to take an active role in decision making and self-care. The use of a mixed-methods research design proved to be an effective approach to not only evaluating outcomes but also examining process issues of the experience. Additional research is greatly needed to better understand potential impacts of integrative approaches to cancer care.

Seeking Mind, Body and Spirit Healing-Why Some Men with Prostate Cancer Choose CAM (Complementary and Alternative Medicine) over Conventional Cancer Treatments.

UNLABELLED: Little is known about men with prostate cancer who decline conventional treatment and use only complementary and alternative medicine (CAM). OBJECTIVES: To 1) explore why men decline conventional prostate cancer treatment and use CAM 2) understand the role of holistic healing in their care, and 3) document their recommendations for health care providers. METHODS: Semi-structured interviews and follow-up focus groups. SAMPLE: Twenty-nine men diagnosed with prostate cancer who declined all recommended conventional treatments and used CAM. RESULTS: Based on strong beliefs about healing, study participants took control by researching the risks of delaying or declining conventional treatment while using CAM as a first option. Most perceived conventional treatment to have a negative impact on quality of life. Participants sought healing in a broader mind, body, spirit context, developing individualized CAM approaches consistent with their beliefs about the causes of cancer. Most made significant lifestyle changes to improve their health. Spirituality was central to healing for one-third of the sample. Participants recommended a larger role for integrated cancer care. CONCLUSION: Men who decline conventional prostate cancer treatment and use CAM only may benefit from a whole person approach to care where physicians support them to play an active role in healing while carefully monitoring their disease status.
