RESUMO
OBJECTIVES: To examine the moderating effect of daylight exposure on physical activity and objective sleep quality, using wearable actigraph devices. METHODS: We recruited 324 patients with either gastric or esophageal cancer. Actigraphs were used to measure all objective data including daylight exposure, physical activity, and sleep quality. Pearson's correlation coefficients were used to examine the relationships among demographic data, disease attributes, physical activity, daylight exposure, and sleep. The Hayes PROCESS macro with the regression bootstrapping method was employed to analyze the moderating effect of daylight exposure on the relationship between physical activity and sleep. RESULTS: Sleep efficiency correlated positively with physical activity, while "wake after sleep onset" correlated negatively with physical activity and mean lux. Mean lux and light >500 lux significantly moderated the association between physical activity and sleep efficiency (Pâ¯=â¯.002 in both cases). Similarly, mean lux and light >500 lux significantly moderated the association between physical activity and "wake after sleep onset" (Pâ¯=â¯.002 and .001, respectively). CONCLUSION: Both average daylight exposure and time of exposure to >500 lux act as moderators of physical activity and objective sleep quality in patients with gastric or esophageal cancer. Healthcare practitioners should encourage patients with cancer to engage in daily outdoor physical activity. Further intervention studies are needed to verify the combined effect of daytime light exposure and physical activity on improving sleep quality. IMPLICATIONS FOR NURSING PRACTICE: Healthcare practitioners should encourage patients with cancer to engage in daily outdoor physical activity. Further intervention studies are needed to verify the combined effect of daytime light exposure and physical activity on improving sleep quality.

BACKGROUND: Although rest-activity circadian rhythm (RACR) disruption is associated with mortality in patients with cancer, few studies have examined the effect of RACR on patients with esophageal and gastric cancer. OBJECTIVE: The aim of this study was to identify the predictors of RACR. METHODS: This cross-sectional, single-site study included 276 patients with esophageal and gastric cancer recruited from chest-surgery and general-surgery outpatient departments. Actigraphy was used to assess objective physical activity (PA), daylight exposure, and RACR, and 3-day PA was used to indicate the subjective amount of PA. The parameter of objective PA was the up activity mean; the parameter of daylight exposure was >500 lx, and the parameters of RACR were the 24-hour correlation coefficient, in-bed less than out-of-bed dichotomy index, midline estimating statistic of rhythm, and amplitude. The subjective amount of PA was calculated as the sum of mild, moderate, and vigorous PA. RESULTS: The up activity mean predicted 24-hour correlation coefficient. The PA amount and up activity mean predicted in-bed less than out-of-bed dichotomy index. The up activity mean and >500-lx daylight exposure predicted midline estimating statistic of rhythm. Finally, the PA amount and up activity mean predicted the amplitude. CONCLUSIONS: Increased PA and daylight exposure may improve RACR. IMPLICATIONS FOR PRACTICE: Patients with esophageal and gastric cancer should be encouraged to engage in outdoor PA during the daytime as part of their regular lifestyle to maintain a robust circadian rhythm.

Alzheimer's disease is characterized by the accumulation of amyloid-ß plaques, aggregation of hyperphosphorylated tau (pTau), and microglia activation. Galectin-3 (Gal3) is a ß-galactoside-binding protein that has been implicated in amyloid pathology. Its role in tauopathy remains enigmatic. Here, we showed that Gal3 was upregulated in the microglia of humans and mice with tauopathy. pTau triggered the release of Gal3 from human induced pluripotent stem cell-derived microglia in both its free and extracellular vesicular-associated (EV-associated) forms. Both forms of Gal3 increased the accumulation of pathogenic tau in recipient cells. Binding of Gal3 to pTau greatly enhanced tau fibrillation. Besides Gal3, pTau was sorted into EVs for transmission. Moreover, pTau markedly enhanced the number of EVs released by iMGL in a Gal3-dependent manner, suggesting a role of Gal3 in biogenesis of EVs. Single-cell RNA-Seq analysis of the hippocampus of a mouse model of tauopathy (THY-Tau22) revealed a group of pathogenic tau-evoked, Gal3-associated microglia with altered cellular machineries implicated in neurodegeneration, including enhanced immune and inflammatory responses. Genetic removal of Gal3 in THY-Tau22 mice suppressed microglia activation, reduced the level of pTau and synaptic loss in neurons, and rescued memory impairment. Collectively, Gal3 is a potential therapeutic target for tauopathy.

BACKGROUND: Physical activity and daylight exposure predict rest-activity circadian rhythm (RACR) in patients with cancer. However, whether daylight exposure mediates the relationship between physical activity and RACR and the optimal amounts of physical activity and daylight that benefit RACR remain unclear. OBJECTIVES: This study investigated the mediating role of daylight exposure and determined the dose-response relationship among daylight exposure, physical activity, and RACR in patients with cancer. METHODS: This cross-sectional exploratory study recruited 319 patients with esophageal and gastric cancer from 2 surgery outpatient departments in Taiwan. Daylight exposure (>500 lux), physical activity (up activity mean), and RACR (midline estimating statistic of rhythm) were measured through actigraphy. Regression was performed, and the receiver operating characteristic curve was plotted. RESULTS: Daylight exposure (>500 lux) partially mediated the relationship between physical activity (up activity mean) and RACR (midline estimating statistic of rhythm). The optimal cutoffs for discriminating between satisfactory and poor RACR were 187.43 counts/min for physical activity (sensitivity, 90.3%; specificity, 84.4%) and 35.71 min/d for daylight exposure (sensitivity, 55.9%; specificity, 78.2%). CONCLUSIONS: Participants who engaged in physical activity were more likely to receive daylight exposure and experience improved RACR. The optimal level of daylight exposure and frequency of physical activity that can improve RACR in patients with esophageal and gastric cancer are 36 min/d and 187 counts/min, respectively. IMPLICATIONS FOR PRACTICE: Healthcare professionals should encourage patients to engage in exercise or physical activity during the daytime to improve their circadian rhythm.
RESUMO
OBJECTIVES: Neisseria meningitidis is one of the major pathogens of meningitis in children worldwide and causes invasive meningococcal disease (IMD), which is a critical illness that mainly presents as meningitis and/or septicemia in children. Identification of N. meningitidis in cerebrospinal fluid (CSF) is the gold standard for the diagnosis of meningococcal meningitis, but antigen tests have advantages such as timely results, relatively low cost, and convenience. Yet, the diagnostic accuracy of antigen tests remains uncertain. Therefore, the aim of this meta-analysis was to evaluate the diagnostic accuracy of antigen tests for N. meningitidis in CSF. METHODS: We searched the PubMed, Embase, and Cochrane Library databases for studies evaluating the diagnostic accuracy of antigen tests for N. meningitidis in CSF. We included studies that provided sufficient data to construct a 2 × 2 table on a per-sample basis. To determine the overall sensitivity and specificity of the antigen tests, we used polymerase chain reaction (PCR) as the reference standard and employed the hierarchical summary receiver operating characteristic model. RESULTS: Nine studies with 4533 CSF samples were included. The meta-analysis yielded a pooled sensitivity of 91.2% (95% confidence interval [CI]: 80.0%-100.0%) and a pooled specificity of 93.8% (95% CI: 83.9%-100.0%). A subgroup analysis of 2 studies that reported the outcomes of MeningoSpeed yielded a pooled sensitivity of 93.4% (95% CI: 90.0%-95.8%) and a pooled specificity of 91.9% (95% CI: 88.6%-94.4%). Antigen testing for the N. meningitidis serogroup X had a pooled sensitivity of 92.4% (95% CI: 85.2%-96.2%) and a pooled specificity of 99.2% (95% CI: 78.7%-100.0%). CONCLUSIONS: The studied antigen tests had high sensitivity and specificity for the diagnosis of meningococcal meningitis in CSF specimens. Antigen testing could serve as an accurate diagnostic method for assessing patients who have a suspected N. meningitidis infection.
RESUMO
Microbiota-gut-brain axis signaling plays a pivotal role in mood disorders. The communication between the host and the gut microbiota may involve complex regulatory networks. Previous evidence showed that host-fecal microRNAs (miRNAs) interactions partly shaped gut microbiota composition. We hypothesized that some miRNAs are correlated with specific bacteria in the fecal samples in patients with major depressive disorder (MDD), and these miRNAs would show enrichment in pathways associated with MDD. MDD patients and healthy controls were recruited to collect fecal samples. We performed 16S ribosome RNA sequence using the Illumina MiSeq sequencers and analysis of 798 fecal miRNAs using the nCounter Human-v2 miRNA Panel in 20 subjects. We calculated the Spearman correlation coefficient for bacteria abundance and miRNA expressions, and analyzed the predicted miRNA pathways by enrichment analysis with false-discovery correction (FDR). A total of 270 genera and 798 miRNAs were detected in the fecal samples. Seven genera (Anaerostipes, Bacteroides, Bifidobacterium, Clostridium, Collinsella, Dialister, and Roseburia) had fold changes greater than one and were present in over 90% of all fecal samples. In particular, Bacteroides and Dialister significantly differed between the MDD and control groups (p-value < 0.05). The correlation coefficients between the seven genera and miRNAs in patients with MDD showed 48 pairs of positive correlations and 36 negative correlations (p-value < 0.01). For miRNA predicted functions, there were 57 predicted pathways with a p-value < 0.001, including MDD-associated pathways, axon guidance, circadian rhythm, dopaminergic synapse, focal adhesion, long-term potentiation, and neurotrophin signaling pathway. In the current pilot study, our findings suggest specific genera highly correlated with the predicted miRNA functions, which might provide clues for the interaction between host factors and gut microbiota via the microbiota-gut-brain axis. Follow-up studies with larger sample sizes and refined experimental design are essential to dissect the roles between gut microbiota and miRNAs for depression.

The kidney has large regenerative capacity, but this is compromised when kidney damage is excessive and renal tubular epithelial cells (TECs) undergo SNAI1-driven growth arrest. Here we investigate the role of IL11 in TECs, kidney injury and renal repair. IL11 stimulation of TECs induces ERK- and p90RSK-mediated GSK3ß inactivation, SNAI1 upregulation and pro-inflammatory gene expression. Mice with acute kidney injury upregulate IL11 in TECs leading to SNAI1 expression and kidney dysfunction, which is not seen in Il11 deleted mice or in mice administered a neutralizing IL11 antibody in either preemptive or treatment modes. In acute kidney injury, anti-TGFß reduces renal fibrosis but exacerbates inflammation and tubule damage whereas anti-IL11 reduces all pathologies. Mice with TEC-specific deletion of Il11ra1 have reduced pathogenic signaling and are protected from renal injury-induced inflammation, fibrosis, and failure. In a model of chronic kidney disease, anti-IL11 therapy promotes TEC proliferation and parenchymal regeneration, reverses fibroinflammation and restores renal mass and function. These data highlight IL11-induced mesenchymal transition of injured TECs as an important renal pathology and suggest IL11 as a therapeutic target for restoring stalled endogenous regeneration in the diseased kidney.

BACKGROUND: The Mild Behavioral Impairment Checklist (MBI-C) has been developed to assess mild behavioral impairment (MBI). However, no study has validated the use of MBI-C using a promising translation method in Taiwan. Thus, consistency and discrepancy between informant-rated and self-rated scores have not been extensively researched. OBJECTIVE: This study validated and compared the informant- and self-rated versions of the MBI-C among community-dwelling people in Taiwan. METHOD: We recruited 202 pairs of individuals without dementia aged ≥50 years and their cohabitating informants. The participants completed the MBI-C (MBI-C-self), and the informants completed the MBI-C (MBI-C-informant) and the Neuropsychiatric Inventory Questionnaire (NPI-Q) independently. Internal consistency, inter-rater reliability, and convergent validity were examined. RESULTS: Both MBI-C-self and MBI-C-informant exhibited satisfactory Cronbach's α values (0.92 and 0.88, respectively). The MBI-C-informant total scorewas correlated with the NPI-Q total score (r = 0.83, p < 0.001). Inter-rater reliability between the two versions, as represented by the inter-rater correlation coefficient, was 0.57 (p < 0.001). The prevalence of MBI based on the MBI-C-informant scores was 1.5% higher than that based on the MBI-C-self scores according to the suggested cut-off score of 8.5. The affective dysregulation domain score of MBI-C-informant was significantly lower than that of MBI-C-self. CONCLUSION: MBI-C-informant exhibited both high reliability and validity. Discrepancies between MBI-C-informant and MBI-C-self related to the detection rates and affective dysregulation domain scores were noted. The level of consistency and discrepancy between these two versions provide implications for the use of MBI-C in clinical practice and future research.

BACKGROUND: Huntington's disease (HD) is a neurodegenerative disease caused by CAG-repeat expansions (>36) in exon 1 of HTT, which dysregulates multiple cellular machineries. Translin-associated protein X (TRAX) is a scaffold protein with diverse functions, including suppressing the microRNA (miRNA)-mediated silencing by degrading pre-miRNA. To date, the role of TRAX in neurodegenerative diseases remains unknown. OBJECTIVES: We delineated the role of TRAX upregulation during HD progression. METHODS: Expression of TRAX in the brains of humans and three mouse models with HD were analyzed by immunohistochemistry staining, western blot, and quantitative reverse transcription-polymerase chain reaction. Adeno-associated viruses harboring TRAX short hairpin RNA were intrastriatally injected into HD mice to downregulate TRAX. HD-like symptoms were analyzed by behavioral and biochemical assessments. The miRNA-sequencing and RNA-sequencing analyses were used to identify the TRAX- regulated miRNA-messenger RNA (mRNA) axis during HD progression. The identified gene targets were validated biochemically in mouse and human striatal cells. RESULTS: We discovered that TRAX was upregulated in the brains of HD patients and three HD mouse models. Downregulation of TRAX enhanced 83 miRNAs (including miR-330-3p, miR-496a-3p) and subsequently changed the corresponding mRNA networks critical for HD pathogenesis (eg, DARPP-32 and brain-derived neurotrophic factor). Disruption of the TRAX-mediated miRNA-mRNA axis accelerated the progression of HD-like symptoms, including the degeneration of motor function, accumulation of mHTT aggregates, and shortened neurite outgrowth. CONCLUSIONS: We demonstrated that TRAX upregulation is authentic and protective in HD. Our study provides a novel layer of regulation for HD pathogenesis and may lead to the development of new therapeutic strategies for HD. © 2022 International Parkinson and Movement Disorder Society.

BACKGROUND: Up to 90% of patients still experience pain after abdominal surgery, which also affects their physical recovery and psychological anxiety. AIM: To evaluate the effects of guided imagery meditation on ameliorating anxiety, improving the quality of sleep, and relieving postoperative pain in patients after laparoscopic cholecystectomy surgery. METHOD: In the general surgical ward of a teaching hospital, patients were randomly assigned to usual care (n = 34) and guided imagery meditation intervention (n = 34) groups, using the method. The measuring outcomes included their anxiety score, quality of sleep, and pain control. RESULTS: In terms of the anxiety difference, the experimental group scored 0.42 (standard deviation [SD] = 0.97), while the control group scored 4.79 (SD = 7.56), which indicates a statistically significant difference (F = 8.04, p = .01, partial eta2 = 0.11). In terms of quality of sleep, the mean score of the experimental group was 2.67 (SD = 1.96), while the control group scored 7.55 (SD = 3.81), which indicates a significant difference (F = 39.99, p = .001, partial eta2 = 0.39). The mean of the degree of postoperative pain was 2.11 points (SD = 1.39), and the score of the control group was 4.00 points (SD = 1.62), which indicates a significant difference (p = .001). CONCLUSIONS: Guided imagery meditation is a simple, non-invasive, non-pharmacologic intervention measure. It can reduce anxiety and postoperative pain, and improve the quality of sleep. Thus, it should be promoted in clinical practice.

OBJECTIVES: In this study, we examined predictors of exercise adherence, contamination and dropout in lung and oesophageal cancer patients who participated in two randomised controlled trials. METHODS: We used data on 188 lung and oesophageal cancer patients from two previous studies (intervention: moderate-intensity walking for 12 weeks). Baseline measurements included demographic variables, disease characteristics, Hospital Anxiety and Depression Scale and Bouchard 3-day physical activity (PA) record. We used multiple linear and logistic regressions to analyse predictors of exercise adherence in the walking group, contamination in the control group and dropout in both groups. RESULTS: Pre-intervention exercise habits and baseline depression scores predicted adherence, with an explanatory power of 16.7% (p < 0.0001). Pre-intervention exercise habits (odds ratio [OR] 19.65, 95% confidence interval [CI] 2.76-139.97), baseline moderate PA (min/day) (OR 1.03, 95% CI 1.01-1.05) and baseline vigorous PA (min/day) (OR 1.09, 95% CI 1.01-1.18) predicted contamination. Baseline mild PA (10 min/day) (OR 0.94, 95% CI 0.89-0.99) predicted dropout. CONCLUSIONS: Pre-intervention exercise habits and baseline depression levels predicted exercise adherence in the walking group. In the control group, pre-intervention exercise habits and baseline moderate and vigorous PA predicted contamination. Baseline mild PA predicted dropout rates in both groups.

BACKGROUND: Computerized cognitive training (CCT) is an emerging alternative intervention for stroke survivors. OBJECTIVE: This study investigated the effects of CCT on the cognition, activity, and participation of stroke survivors and compared the findings with those of match-dosed conventional cognitive training. METHODS: This randomized controlled trial included 39 patients with stroke who were divided into the intervention group (nâ=â19; receiving CCT with Lumosity software) and the control group (nâ=â20; receiving conventional cognitive training). Both the groups were trained for 20 min, twice a week, for 12 weeks. Participants were evaluated at pretest, posttest, and 4-week follow-up. Outcome measures included various cognitive function tests and the Stroke Impact Scale scores. RESULTS: The CCT group exhibited significant improvement in global cognitive function (evaluated using the Mini-Mental State Examination and Montreal Cognitive Assessment) and specific cognitive domains: verbal working memory (backward digit span test), processing speed (Symbol Digit Modalities Test), and three MoCA subtests (attention, naming, and delayed recall). CCT exerted no significant effect on activities and participation. No significant between-group differences in changes in cognitive function were noted. However, CCT significantly improved cognitive function domains immediately after training, and these effects were sustained at the 4-week follow-up. CONCLUSIONS: Cognitive function of individuals with chronic stroke could improve after administration of CCT. However, future studies with a more rigorous design and higher training dose are warranted to validate our findings.

The purpose of this study is to investigate the relationships among disease knowledge, self-efficacy, and quality of life in patients with hypertensive nephropathy. A cross-sectional and correlational design is employed in this study, and a total of 213 participants are collected by convenience sampling from the outpatient Department of Nephrology of a regional teaching hospital in Taiwan. The research instruments include the Hypertensive Nephropathy Knowledge Instrument, the Chronic Kidney Disease Self-Efficacy Instrument, and the Medical Outcome Study Short Form-12, and stepwise multiple regression analysis is used to test the explanatory power of each significantly-correlated independent variable regarding the quality of life. The results show that the higher the disease knowledge, the better the self-efficacy, and the better the quality of life, and self-efficacy is the most important predictor of the quality of life.

BACKGROUND: Polyglutamine (polyQ) diseases are dominant neurodegenerative diseases caused by an expansion of the polyQ-encoding CAG repeats in the disease-causing gene. The length of the CAG repeats is the major determiner of the age at onset (AO) of polyQ diseases, including Huntington's disease (HD) and spinocerebellar ataxia type 3 (SCA3). OBJECTIVE: We set out to identify common genetic variant(s) that may affect the AO of polyQ diseases. METHODS: Three hundred thirty-seven patients with HD or SCA3 were enrolled for targeted sequencing of 583 genes implicated in proteinopathies. In total, 16 genes were identified as containing variants that are associated with late AO of polyQ diseases. For validation, we further investigate the variants of PIAS1 because PIAS1 is an E3 SUMO (small ubiquitin-like modifier) ligase for huntingtin (HTT), the protein linked to HD. RESULTS: Biochemical analyses revealed that the ability of PIAS1S510G to interact with mutant huntingtin (mHTT) was less than that of PIAS1WT , resulting in lower SUMOylation of mHTT and lower accumulation of insoluble mHTT. Genetic knock-in of PIAS1S510G in a HD mouse model (R6/2) ameliorated several HD-like deficits (including shortened life spans, poor grip strength and motor coordination) and reduced neuronal accumulation of mHTT. CONCLUSIONS: Our findings suggest that PIAS1 is a genetic modifier of polyQ diseases. The naturally occurring variant, PIAS1S510G , is associated with late AO in polyQ disease patients and milder disease severity in HD mice. Our study highlights the possibility of targeting PIAS1 or pathways governing protein homeostasis as a disease-modifying approach for treating patients with HD. © 2021 International Parkinson and Movement Disorder Society.

BACKGROUND: Esophageal cancer patients experience severe symptoms and poor quality of life. OBJECTIVE: We examined the effects of a rehabilitation program on quality of life, sleep, rest-activity rhythms, anxiety, and depression of esophageal cancer patients. METHODS: Forty-four patients with esophageal cancer were randomly assigned to an experimental group, which underwent a 12-week brisk walking and diet education program, or a control group, which received standard care. Health-related quality of life, subjective and objective sleep quality, rest-activity rhythms, anxiety, and depression were assessed at baseline and post intervention. RESULTS: A generalized estimating equation analysis revealed that, after intervention, compared with the control group, the experimental group exhibited significantly improved reflux (P = .022; effect size, 0.32) and marginally improved emotional (P = .069; effect size, 0.27) and social (P = .069; effect size, 0.27) functions; constipation (P = .050; effect size, 0.29), eating difficulty (P = .058; effect size, 0.27), anxiety (P = .050; effect size, 0.29), and total sleep time (P = .068; effect size, 0.39). CONCLUSIONS: The rehabilitation program may improve health-related quality of life and sleep and alleviate anxiety in patients with esophageal cancer. IMPLICATIONS FOR PRACTICE: A rehabilitation program comprising exercise and diet education is a feasible and low-cost intervention for improving quality of life of patients with esophageal cancer. Healthcare team members may consider it as a nonpharmacological treatment option for patients.

Recent studies have suggested that gut-brain axis may be one of the mechanisms of major depression disorder (MDD). The current study aimed to investigate the effects of Lactobacillus plantarum PS128 (PS128) on psychophysiology in patients with MDD. We recruited 11 patients with MDD and gave them PS128 for 8 weeks. We compared depression symptoms, serum markers of inflammation and gut permeability, and gut microbiota before and after 8-week intervention and also explored the correlations among symptoms, biomarkers, and gut microbiota. After 8-week PS128 intervention, scores of Hamilton Depression Rating Scale-17 and Depression and Somatic symptoms Scale significantly decreased. Serum levels of high sensitivity c-reactive protein, interluekin-6, and tumor necrosis factor-α, zonulin and intestinal fatty acid binding protein, and the composition of gut microbiota did not significantly change after 8-week PS128 intervention. However, we found changes of some genera were correlated with changes of symptoms and biomarkers. In conclusion, this is an open trial with small sample size and has several limitations. The results need to be verified by randomized, double-blind, placebo-controlled trial with larger sample size.

Tau pathology is instrumental in the gradual loss of neuronal functions and cognitive decline in tauopathies, including Alzheimer's disease (AD). Earlier reports showed that adenosine metabolism is abnormal in the brain of AD patients while consequences remained ill-defined. Herein, we aimed at investigating whether manipulation of adenosine tone would impact Tau pathology, associated molecular alterations and subsequent neurodegeneration. We demonstrated that treatment with an inhibitor (J4) of equilibrative nucleoside transporter 1 (ENT1) exerted beneficial effects in a mouse model of Tauopathy. Treatment with J4 not only reduced Tau hyperphosphorylation but also rescued memory deficits, mitochondrial dysfunction, synaptic loss, and abnormal expression of immune-related gene signatures. These beneficial effects were particularly ascribed to the ability of J4 to suppress the overactivation of AMPK (an energy reduction sensor), suggesting that normalization of energy dysfunction mitigates neuronal dysfunctions in Tauopathy. Collectively, these data highlight that targeting adenosine metabolism is a novel strategy for tauopathies.

AIM AND OBJECTIVES: To evaluate the effect of patient-centred self-management programme on mental health, self-efficacy and self-management of patients with hypertensive nephropathy. BACKGROUND: If the symptoms of hypertension are not well-controlled, deterioration of renal function will accelerate and evolve into hypertensive nephropathy. DESIGN: A randomised single-blind trial. This article follows the requirements of CONSORT statement. METHODS: The experimental group (n = 35) after pre-test used patient-centred self-management programme once a week for a total of 4 weeks and the intervention effect was measured after 3 months for post-test. Contrarily, the traditional care was employed for the control group (n = 35). The measuring outcomes included mental health, self-efficacy and self-management. Trial registry is listed under https://clinicaltrials.gov/ with Identifier No. NCT04633993. RESULTS: After the intervention, the average score of mental health for the experimental group was 20.79 (SD = 0.82) which was higher than the 19.27 points for the control group (SD = 0.77) and showed a significant difference (F = 8.31, p = .005, partial eta2 = 0.133). In terms of self-efficacy, the average score for the experimental group was 214.13 (SD = 6.40), which was higher than the 189.58 points for the control group (SD = 6.03) and exhibited a significant difference (F = 11.82, p = .001, partial eta2 = 0.197). Regarding self-management, the average score of the experimental group was 75.12 (SD = 2.29) which was significantly higher than the 68.80 points of the control group (SD = 2.43) (F = 11.17, p = .001, partial eta2 = 0.190). CONCLUSIONS: In addition to promoting mental health of individual cases, this intervention also increases their self-confidence in disease control and improves their self-management on diseases. RELEVANCE TO CLINICAL PRACTICE: The intervention provides an effective option for clinical care workers as a replacement for or supplement to the traditional care.

OBJECTIVES: To identify factors associated with mammography screening behaviour and its predictors among rural Vietnamese women. METHOD: A predictive correlational study involving 120 women aged ≥ 40 years was conducted in the suburbs of Hanoi, Vietnam, in July 2018 by using Breast Cancer Awareness Measurement and the Champion Health Beliefs Model Scale. Mammography screening behaviour was assessed by asking participants about their previous mammography experience. RESULTS: Only 16.7% of participants had undergone mammography screening. High education levels, high monthly family income, having family members or friends with breast cancer, and receiving physicians' recommendations increased the likelihood of participants screening for breast cancer. Mean scores on perceived susceptibility and perceived barriers differed significantly between participants who had and those who had not undergone screening (t = 4.31; p < .001; t = -5.05; p < .001, respectively). Perceived susceptibility and perceived barriers significantly increased the predictive power of the hierarchical logistic model (critical value = 6.16; [df = 2]; p = .046). Perceived barriers were the most significant predictors of screening behaviour (odds ratio 0.84; 95% CI, 0.71-0.99; p = .039). CONCLUSION: Efforts are necessary to increase mammography awareness in the community and promote screening rates in Vietnam.

About one-third of admissions to the surgical unit annually are diabetes foot infections in need of amputation In St. Kitts and Nevis. However, the risk factors related to diabetes foot and amputation remain unknown. This study investigated factors associated with diabetic foot and amputation (DFA). Retrospective case control study design, and purposive and quota sampling method was used to recruit the participants. Patients with and without DFA were interviewed at two main hospitals, several primary health centres, and a private doctor's office during July and August 2018. Self-development questionnaires were applied to assess patients' demographic, physical and behaviour, foot care knowledge, attitudes, and practices related to DFA. Chi-square, t-test, and multiple logistic regressions were used to analyse the data. A total of 210 patients were evaluated, 89 had DFA, while 121 did not, with a mean age of 61.10 (SD = 11.85). Participants' responses indicated good knowledge, favourable attitudes, and adequate practices related to foot care. The two items of the questionnaire, ways to maintain blood flow in the lower extremities and wash their feet daily, had significant lower score in DFA group. In multiple logistic regression, knowledge, attitudes, and practices related to foot care were not a significant predictor of DFA. Being male was a predictor of DFA than female (OR = 3.53; 95% CI = 1.65-7.57; P < .01). Participants who were currently unemployed were less likely to have DFA than those who were employed (OR = 0.38; 95% Cl = 0.17-0.86; P < .05). Comparing patients with the longest experience of diabetes mellitus (31 years or more) with those who had diabetes for the shortest period of time (between 1 and 10 years) was less likely to have DFA (OR = 0.38; 95% CI = 0.15-0.97; P = <.05). The combination of these independent variables could explain 29% of the variance in DFA. Based on these findings, strategies to prevent diabetic foot and amputation should focus on male and outdoor heavy worker, and longer duration of diabetes patients which are identified in this study.
