Comparative analysis of diagnostic methods and risk factors for Aelurostrongylus abstrusus infection in brazilian cats.

This study aimed to prospectively evaluate the risk factors of infection by Aelurostrongylus abstrusus in Brazilian cats with cough and/or radiographic changes, using as diagnostic tools the Baermann method (BM), polymerase chain reaction (PCR) of feces, bronchoalveolar lavage fluid (BALF), and cytology. Forty-three cats that were presented with cough or lung radiographic abnormalities compatible with bronchoalveolar disease were included in the study. After clinical evaluation, feces samples were collected to investigate lungworm parasitism through BM and PCR. BALF was performed to provide samples for cytology, bacteriology, and fungal culture. Stool PCR was considered the gold standard for diagnosis tests, and the other methods were evaluated by their agreement. PCR presented 74% (32/43) of positivity for A. abstrusus, while in the BM, 41% (18/43) were positive. BM showed sensitivity of 56.25% and specificity of 100% when compared with PCR. No larva was found in the cytological evaluation of 21 BALF samples. Lungworm is an important cause of bronchopulmonary disease in domestic cats in Brazil and should be included as a differential diagnosis when a cat is presented with cough or radiographic abnormalities. BM is a sensitive, non-invasive, and cheap technique to diagnose the disease, but it is not as sensitive as PCR.

Antimicrobial resistance of Pseudomonas aeruginosa isolated from patients with pneumonia during the COVID-19 pandemic and pre-pandemic periods in Northeast Brazil.

Healthcare-related infections caused by resistant microorganisms are a severe public health problem and are becoming increasingly prevalent in the hospital environment, especially Pseudomonas aeruginosa. This work aimed to evaluate the resistance profile of Pseudomonas aeruginosa to antimicrobials before the COVID-19 pandemic and during the pandemic period. Bacteria strains were obtained from tracheal aspiration, sputum, and bronchoalveolar lavage for diagnosis and phenotypic characterization. Matrix assisted laser-desorption ionization-time of flight mass spectrometry (MALD-TOF MS) was used to identify strains. Automated Phoenix and VITEK® 2 Compact system and the disc diffusion method were performed to determine the antimicrobial susceptibility profile. A total of 41,000 medical reports from adult patients with pneumonia were analyzed. Of these, 951 patients were positive for P. aeruginosa, of which 373 were related to the pre-pandemic period and 578 to the pandemic period. Older men (≥60 years) were more prevalent in both periods. P. aeruginosa strains were resistant to imipenem in both periods: 38.8 and 42.5%, respectively, followed by meropenem (34.2 and 39.2%), ciprofloxacin (33.6 and 36.7%), and levofloxacin (34.9 and 43.5%). Intensive care units had the highest percentage of affected patients (62 and 65%) compared with other sectors, with a prevalence of 71% in the public network before COVID-19 and 59% during the pandemic. Our data showed a prevalence of P. aeruginosa in elderly patients in both the pre-pandemic and pandemic periods. In addition, an increase in P. aeruginosa resistance to beta-lactams, quinolones, carbapenems, and cephalosporins was observed during the COVID-19 pandemic compared with the period before the pandemic, especially in ICUs.

Literature review and development of pictorial action plan to promote self-management of chronic obstructive pulmonary disease.

OBJECTIVE: This study aimed to review relevant literature and develop a pictorial action plan (PAP) to enhance self-management among older patients with chronic obstructive pulmonary disease (COPD). METHODS: In Stage 1, an integrative review was conducted to identify key elements of respiratory self-management action plans. In Stage 2, cartoon pictograms with plain descriptions were designed. In Stage 3, the PAP was validated by 40 older patients with COPD and an expert panel. RESULTS: While the eight included studies demonstrated positive effects on knowledge and quality of life, key elements identified included: traffic light motif, plain and explicit language, and several action plan topics. The final PAP comprises three traffic light-coloured zones and 24 pictograms that introduce self-management strategies for normal, decreasing, and severely decreased airflow. After revising the cartoon characters, all of the pictograms received guessability ratings above 70% and acceptable mean translucency ratings. DISCUSSION: The integrative review provides evidence about the effectiveness and key elements of PAPs. The PAP developed was found to be valid and feasible for use among older patients with chronic respiratory conditions. PRACTICE IMPLICATIONS: This study offered an example of translating evidence into patient education practice to enhance self-management in older patients with COPD.

Financial well-being as a mediator of the relationship between multimorbidity and health-related quality of life in people with cancer.

BACKGROUND: It is unknown whether financial well-being mediates the impact of multimorbidity on the health-related quality of life (HRQoL) of cancer patients. METHODS: Participants were recruited from three outpatient oncology clinics of Hong Kong public hospitals. Multimorbidity was assessed using the Charlson Comorbidity Index. Financial well-being, the mediator of the association between multimorbidity and HRQoL outcomes, was assessed using the Comprehensive Score for Financial Toxicity Functional Assessment of Chronic Illness Therapy. The HRQoL outcomes were assessed using the Functional Assessment of Cancer Therapy - General (FACT-G) and its four sub-dimensions. Mediation analyses were conducted using SPSS PROCESS v4.1. RESULTS: Six-hundred and forty cancer patients participated in the study. Multimorbidity had a direct effect on FACT-G scores independent of financial well-being (ß for path c' = -0.752, p < 0.001). In addition, multimorbidity had an indirect effect on FACT-G scores through its effect on financial well-being (ß for path a = -0.517, p < 0.05; ß for path b = 0.785, p < 0.001). Even after adjustments were made for the covariates, the indirect effect of multimorbidity on FACT-G via financial well-being remained significant, accounting for 38.0% of the overall effect, indicating partial mediation. Although there were no statistically significant associations between multimorbidity, social well-being, and emotional well-being, the indirect effects of multimorbidity on physical and functional well-being through financial well-being remained significant. CONCLUSIONS: Poor financial well-being attributable to multimorbidity partially mediates the direct impact of chronic conditions on HRQoL in Chinese cancer patients, particularly their physical and functional well-being.

Hypoglycemic effect of Coffea arabica leaf extracts and major bioactive constituents.

The present study focused on investigating the antioxidant, antiglycation activity, digestive enzymes inhibition, bioaccessibility and hypoglycemic effect of C. arabica leaves extracts. The extracts deactivated the O2•-, ROO•, H2O2, HOCl reactive oxygen species. Coffee leaves showed strong inhibition of α-glucosidase (IC50 = 40.30 µg mL-1) greater than the isolated metabolites and acarbose. There was also inhibition of pancreatic lipase (IC50 = 56.43 µg mL-1) in addition to a hypoglycemic effect in zebrafish similar to acarbose and metformin. With the exception of rutin, all biocompounds were detected at all stages of in vitro digestion. Finally, these results suggest that C. arabica leaf extracts possess antidiabetic and anti-obesity properties that can be attributed to the main metabolites and the synergistic action between them.Communicated by Ramaswamy H.

The Feasibility and Acceptability of a Needs-Oriented Psychoeducational Intervention Among Caregivers of Adolescent and Young Adult Cancer Patients: A Pilot Randomized Controlled Trial.

BACKGROUND: Little is known about the psychoeducational interventions for caregivers of adolescent and young adult (AYA) cancer patients. OBJECTIVE: To evaluate the feasibility and acceptability of a needs-oriented psychoeducational intervention among caregivers of AYA cancer patients. METHODS: In this 2-arm (parallel-group), pilot randomized controlled trial, participants were randomized to the intervention or control group. Participants in the control group received usual care, whereas those in the intervention group received a needs-oriented psychoeducational intervention via WeChat as well as the usual care. Feasibility was evaluated on recruitment, attrition, and adherence rates and the data collection process. Acceptability was assessed based on participants' satisfaction with and perceived usefulness of the intervention, collected using a questionnaire. In addition, a semistructured interview was conducted to explore their experiences. RESULTS: Twenty-four caregivers of AYA cancer patients were recruited, with a consent rate of 61.5%. The attrition and response rates 5 weeks after baseline were 8.3% and 91.7%. Among the 12 participants in the intervention group, 10 (83.3%) completed all of the 5 weekly sessions. Most of the participants were satisfied with the program and perceived its usefulness. The semistructured interviews revealed 3 major categories: facilitators of participation, perception of the intervention, and perceived benefits. CONCLUSIONS: The needs-oriented psychoeducational intervention delivered through WeChat is feasible for and acceptable to caregivers of AYA cancer patients. A full-scale study is warranted to examine the effects of this intervention on caregivers' health outcomes. IMPLICATIONS FOR PRACTICE: The WeChat-based, needs-oriented psychoeducational intervention may be beneficial to improve caregivers' health outcomes.

Retraining programme for older patients undergoing peritoneal dialysis: A randomised controlled trial.

BACKGROUND: Peritonitis is a common cause of hospitalisation and death among patients undergoing peritoneal dialysis. Periodic retraining is recommended to prevent peritonitis, especially in older adults. OBJECTIVES: We evaluated the effectiveness of a retraining programme for reducing peritonitis and exit site infection rates in older adults on peritoneal dialysis. The cost-benefit ratio was also calculated. DESIGN: A two-arm prospective randomised controlled trial. PARTICIPANTS: One hundred and thirty patients aged 55 years or older were recruited. Participants were randomly assigned to the intervention or control group. While both groups received usual care, the intervention group received a retraining programme (a knowledge and practical assessment and a one-on-one retraining session) 90 days after starting home-based continuous ambulatory peritoneal dialysis therapy. MEASUREMENTS: The outcomes included peritonitis rate, exit site infection rate and direct medical costs at 180, 270, and 360 days after starting home-based continuous ambulatory peritoneal dialysis therapy. RESULTS: No significant differences were found in the baseline characteristics between groups. The peritonitis rates were 0.11 episodes per patient-year in the intervention group versus 0.13 in the control group. The incidence of exit site infection was 20.0% in the intervention group and 12.3% in the control group. The cost-benefit ratio of retraining was 1:9.6. None of the results were statistically significant. CONCLUSIONS: The absence of statistical significance may be partly explained by the premature termination of the study. Large-scale multi-centre trials are warranted to examine the effectiveness of retraining. The timing and long-term effects of retraining also need to be examined.

Unmet needs, anxiety, depression, and quality of life among caregivers of adolescents and young adults with cancer: A cross-sectional study.

Objective: To assess unmet needs, anxiety, depression, and quality of life of caregivers of adolescents and young adults with cancer and examine their associations. Methods: A total of 282 caregivers of adolescents and young adults with cancer were recruited by convenience sampling at a tertiary cancer hospital in Chinese Mainland. The participants' unmet needs, anxiety, depression, and quality of life were assessed using self-reported questionnaires. Hierarchical regression analyses were conducted to examine associations between unmet needs and health outcomes. Results: The five most prevalent high unmet needs were related to 'worries about future' and 'information', including dealing with not knowing what lies in the future (n â€‹= â€‹161, 57.1%), dealing with worry about the cancer getting worse (n â€‹= â€‹151, 53.5%), dealing with worry about the cancer coming back (n â€‹= â€‹147, 52.1%), finding information about complementary or alternative therapies (n â€‹= â€‹137, 48.6%), and finding information about the long-term side effects of treatments and medicines (n â€‹= â€‹126, 44.7%). Around 40% of the caregivers reported moderate to severe anxiety and depression. After adjusting for sociodemographic and clinical characteristics, personal and emotional needs, healthcare access and continuity, and financial needs remained significantly associated with anxiety, depression, or quality of life. Conclusions: Nurses need to be aware of the unmet needs of caregivers of adolescents and young adults with cancer. More effort is needed to identify services and interventions that address the unmet needs, particularly personal and emotional, healthcare access and continuity, and financial needs, to improve the caregivers' health outcomes.

Psychometric validation of the Chinese version of the M. D. Anderson Symptom Inventory-Head and Neck Module in patients with nasopharyngeal carcinoma.

Objective: The Chinese version of the M. D. Anderson Symptom Inventory-Head and Neck Module (MDASI-HN-C) has been linguistically validated. However, its psychometric properties have not been established yet. The purpose of the study was to psychometrically validate the MDASI-HN-C in patients with nasopharyngeal carcinoma (NPC). Methods: 130 Chinese NPC patients who were undergoing radiotherapy (RT) participated in this cross-sectional study. The content, convergent, and construct validity of the MDASI-HN-C were examined. The reliability of the instrument was tested by examining the internal consistency and test-retest reliability. Results: Cronbach's α coefficients ranged from 0.85 to 0.91 for the three subscales of the MDASI-HN-C. The 3-day test-retest reliability was acceptable with intraclass correlation coefficients (ICC) ranged from 0.52 to 0.71. The scale content validity index (S-CVI) was satisfactory (0.97). Subscale scores of the MDASI-HN-C were negatively correlated with the total score of the Chinese version of the Functional Assessment of Cancer Therapy-Head and Neck Scale (FACT-H&N-C) as hypothesized (r â€‹= â€‹-0.484 to -0.563, all P â€‹< â€‹0.01). Exploratory factor analysis (EFA) revealed two factors for the 13 core and another two for the nine HNC-specific items. Only one factor was generated for the six interference items. Conclusions: The MDASI-HN-C shows desirable psychometric properties for evaluating symptom burden in NPC patients, which can be used in both clinical and research contexts.

Needs assessment instruments for family caregivers of cancer patients receiving palliative care: a systematic review.

PURPOSE: Family caregivers of palliative cancer patients experience various supportive care needs. Appropriate self-reported instruments with robust psychological properties are required to identify these needs of family caregivers. Therefore, we conducted a systematic review to identify self-reported supportive care needs assessment instruments for family caregivers of palliative cancer patients and assess their contents, psychometric properties, and applicability. METHODS: Systematic searches were conducted in six English databases and four Chinese databases from inception to October 2020 and updated in June 2021. The instruments identified were evaluated using an 18-item checklist consisting of six domains: conceptual model, content validity, reliability, construct validity, scoring and interpretation, and respondent burden and presentation. RESULTS: Six articles, describing four self-reported needs assessment instruments, were included in the review. These instruments varied significantly in terms of contents, constructs, scoring methods, and applicability. Three of these instruments were developed to assess the comprehensive supportive care needs of family caregivers, while one was specifically developed to assess the spiritual needs of family caregivers. With respect to psychometric properties, none of the instruments identified met all the criteria. Three major shortcomings were identified, namely, lack of longitudinal validity, lack of a strategy for interpreting missing data, and lack of a description of the literacy level required to understand the questions. Additionally, the instrument development processes assessed in this study lacked qualitative elements. CONCLUSIONS: End-users need to consider contents, psychometric properties, and applicability when choosing an appropriate needs assessment instrument according to individual purpose and context. Further evaluation or development of needs assessment for the family caregivers of palliative cancer patients is needed, with a particular emphasis on caregivers' perspectives.

Oocyte ERM and EWI Proteins Are Involved in Mouse Fertilization.

In mammalian fertilization, the link between the oocyte plasma membrane and underneath cytoskeleton has often been associated to key elements of successful gamete fusion, like microvilli shaping or CD9 function, but its effective role has poorly been studied. EWI-2 and EWI-F as cis partners of CD9, and ERM proteins (Ezrin, Radixin and Moesin) that both attach to the actin cytoskeleton and to the EWI are part of the molecules that make the link between the oocyte membrane and its cytoskeleton. This study aims to assay through siRNA inhibition, the involvement of these ERM and EWI molecules in mouse fertilization, their role in the microvilli morphology of the egg but also their possible contribution to the cortical tension, a parameter that reflects the mechanical behavior of the oocyte cortex. Whereas inhibiting separately the expression of each protein had no effect on fertilization, the combined inhibition of either EWI-2/EWI-F or the three ERM triggered a significant decrease of the fertilization index. This inhibition seems to correlate with an increase in the radius of curvature of the oocyte microvilli. It also causes a decrease of the oocyte cortical tension. These results show the importance of EWI-2 and EWI-F and ERM proteins in the smooth running of a fertilization event and support their involvement in the microvilli architecture of the oocyte and in its mechanical properties.

Effectiveness of psychoeducational interventions among caregivers of patients with cancer: A systematic review and meta-analysis.

BACKGROUND: Many of the needs of caregivers of patients with cancer are unmet, particularly their informational and psychological needs. Psychoeducational interventions that focus on providing caregivers with information, and on meeting their emotional and psychosocial needs, may therefore be effective. OBJECTIVE: To evaluate the effectiveness of psychoeducational interventions on the outcomes of caregivers of patients with cancer and identify characteristics of effective psychoeducational interventions. DESIGN: A systematic review and meta-analysis of randomised controlled trials. DATA SOURCES: The databases of PubMed, Embase, the Cochrane Central Register of Controlled Trials, Cumulative Index to Nursing and Allied Health Literature Complete, the British Nursing Index, PsycINFO, Ovid Emcare, Scopus, Chinese Journal Net, and Wan Fang Data were searched in December 2020. Clinical trial registers, related websites and reference lists of included studies were also examined. REVIEW METHODS: The Cochrane Risk of Bias Tool was used to appraise the quality of included studies. Meta-analysis was conducted, and narrative syntheses were performed where meta-analysis was inappropriate. RESULTS: Fourteen articles describing 12 studies were included. The results of the meta-analysis showed that psychoeducational interventions have short-term (immediately post-intervention) positive effects on relieving anxiety [SMD: -0.50, 95%CI: (-0.97, -0.02), p = 0.04], depression [SMD: -0.54, 95%CI: (-0.76, -0.32), p < 0.00001] and caregiver burden [SMD: -0.57, 95%CI: (-0.87, -0.27), p = 0.0002] and improving their quality of life [SMD: 0.42, 95%CI: (0.23, 0.62), p < 0.0001) and self-efficacy [SMD: 0.31, 95%CI: (0.09, 0.53), p = 0.006] in the caregivers of patients with cancer. They also showed long-term (at least 3 months post-intervention) positive effects on improving physical health [SMD: 0.26, 95%CI: (0.05, 0.47), p = 0.02]. The types of psychoeducational interventions varied in the 12 studies. However, the main contents of effective psychoeducational interventions included tasks related to health care provisions for patients, caregiver self-care and stress management, and relationship and coping skills. In general, most studies had short follow-up periods and involved caregivers of older patients with cancer (>40 years old). CONCLUSIONS: Psychoeducational interventions may have short-term desirable effects on caregivers' anxiety, depression, quality of life, burden and self-efficacy and long-term desirable effects on physical health. Individual psychoeducational intervention varied in contents, delivery mode, dosage and format. Research is needed to further specify the optimal combination of contents. Further high-quality RCTs are warranted, with longer follow-up periods, for caregivers of patients with cancer, especially caregivers of younger patients with cancer.

Psychological Wellbeing and Associated Factors Among Ethnic Minorities During the COVID-19 Pandemic.

This study assessed the psychological wellbeing and its associated factors amongst ethnic minorities during the coronavirus disease 2019 (COVID-19) pandemic. A total of 310 Hong Kong South Asians aged 41.3 (SD 13.7) years completed an anonymous online survey between July 2020 and February 2021. The results showed an overall moderate level of stress and high levels of depression, anxiety and post-traumatic stress disorder (PTSD) symptoms amongst South Asian minorities. Multivariable regression analyses suggested that being single/divorced, following Hinduism or other non-Muslim religions, having lower perceived knowledge of COVID-19 and having worried about losing job were significant predictors of higher levels of depression, anxiety and/or stress; additionally, being male, having a low monthly household income, having worried about losing job and healthcare collapse were significant predictors of a higher level of PTSD symptoms. The findings suggest an urgent need to alleviate the psychological impacts of the COVID-19 pandemic on ethnic minorities, specifically for those most vulnerable to these impacts.

Discrepancies between nurses' current and perceived necessary practices of family-centred care for hospitalised children and their families: A cross-sectional study.

PURPOSE: This study investigated (1) the discrepancies between the nurses' current and perceived necessary practices of family-centred care (FCC), and (2) the nurses' demographic characteristics associated with current and perceived necessary practices of FCC for hospitalised children and their families in Malawi. DESIGN AND METHODS: A cross-sectional study involving 444 nurses was conducted. The Family-Centred Care Questionnaire-Revised was used to examine the discrepancies between the nurses' current and perceived necessary practices of FCC. Univariate and multivariate statistical analyses were performed to identify the nurses' demographic characteristics associated with current and perceived necessary practices of FCC. RESULTS: The total mean score of the nurses' current practices of FCC (M = 34.78, SD = 7.06) was significantly lower than that of the nurses' practices of FCC that were perceived as necessary (M = 38.63, SD = 5.60, p < 0.001). The nurses who were over 40 years of age (regression coefficient, ß = 9.162, p = 0.014), had a postgraduate qualification (ß = 23.314, p < 0.001), were separated or widowed (ß = 9.661, p = 0.029), had a Tumbuka cultural background (ß = 12.984, p < 0.001), were Seventh-day Adventist members (ß = 8.863, p = 0.026), and worked in mission hospitals (ß = 16.401, p = 0.021) were more likely to implement current practices of FCC. Conversely, the nurses who were members of the Moslem, Buddhist, or Hindi religious denomination (ß = 6.587, p = 0.040), had a Tonga or Ngonde cultural background (ß = 6.625, p = 0.046), and were nurse midwife technicians (ß = -23.528, p = 0.012) were more likely to implement practices of FCC that they perceived as necessary. CONCLUSION: Significant differences between the nurses' current and perceived necessary practices of FCC suggested that there were barriers to implementing necessary practices of FCC. The nurses' cultural and religious backgrounds were predictors of current practices of FCC, and this finding could direct the future development and testing of FCC interventions in Malawi. PRACTICE IMPLICATIONS: Continued educational activities and research on the factors that contributed to the discrepancies between the nurses' current and perceived necessary practices of FCC and their impact on FCC in Malawi are critical.

MC3T3-E1 cell response to microporous tantalum oxide surfaces enriched with Ca, P and Mg.

The formation of a porous oxide surface doped with osteoconductive elements, Ca, P and Mg, to enhance osseointegration, was achieved through micro arc oxidation. Micro arc oxidation parameters, such as electrolyte composition, concentration and applied voltage, were studied to understand their effect on the morphology and chemical composition of the samples surface. Considering the optimum atomic concentration reported in literature for each osteoconductive element, microporous Ta anodic oxide samples treated with calcium acetate (CaA) and ß-glycerophosphate (ß-GP) revealed that an increase of ß-GP molarity in the electrolyte boosts Ca incorporation, as well as, increasing the porosity. In adding magnesium acetate (MgA) to the electrolyte, when composed by CaA + ß-GP, both addition and variation of MgA did not affect the surface morphology along the samples, being incorporated into the oxide layer for 0.1 M. Finally, in vitro tests were carried out to study the biocompatibility of Ta, to verify the cytotoxicity of the samples and their behavior towards cells, by performing adhesion and differentiation tests with the MC3T3-E1 cell line. Cytotoxicity tests revealed that the samples were non-toxic. Despite none of the samples having been raised up through cell adhesion tests, cell differentiation revealed promising results for the Ta-CaP.

The cross-lagged association between depressive symptoms and health-related quality of life in patients receiving maintenance hemodialysis: a three-wave longitudinal study.

PURPOSE: To examine the cross-lagged relationship between depressive symptoms and health-related quality of life (HRQoL) in patients receiving maintenance hemodialysis. METHODS: A longitudinal, observational study was conducted in two public hospitals in Shanghai, China. The sample consisted of 204 patients at baseline (T1). Of these, 144 completed the 12-month follow-up survey (T2), and 135 completed the 24-month follow-up survey (T3). Depressive symptoms were assessed using the depression subscale of the Hospital Anxiety and Depression Scale, and HRQoL was assessed using the Kidney Disease Quality of Life 36 short form. Cross-lagged path analysis was used to examine the temporal relationship between depressive symptoms and domains of health-related quality of life. RESULTS: Lower levels of three out of five domains of HRQoL (physical functioning, burden of kidney disease, and symptoms of kidney disease) at T1 were associated with increases in depressive symptoms at T2. Moreover, higher depressive symptoms at T2 were associated with decreases in four domains of HRQoL (mental functioning, burden of kidney disease, symptoms of kidney disease, and effects of kidney disease) at T3. CONCLUSIONS: Patients who had poor HRQoL were more likely to report more subsequent depressive symptoms, which in turn predict lower HRQoL over time. It indicates a need to break this cycle in patients receiving maintenance hemodialysis.

Association of single nucleotide polymorphisms of cytochrome P450 enzymes with experience of vasomotor, vaginal and musculoskeletal symptoms among breast cancer patients: a systematic review.

BACKGROUND: Adjuvant endocrine therapies are known to induce undesirable adverse effects such as vasomotor, vaginal and musculoskeletal symptoms among breast cancer patients. Drugs used in these therapies are often metabolised by cytochrome P450 (CYP) enzymes, in which their metabolising activities can be modified by single nucleotide polymorphisms (SNP) in CYP genes and CYP genotypes. This review aims to explore whether SNPs or genotypes of CYP are associated with the occurrence, frequency and severity of vasomotor, vaginal and musculoskeletal symptoms in breast cancer patients on adjuvant endocrine therapies. METHODS: A literature review was conducted using five electronic databases, resulting in the inclusion of 14 eligible studies, and their findings were presented narratively. Selected items from the Strengthening the Reporting of Observational Studies in Epidemiology (STROBE) checklist were used for critical appraisal of the reporting quality of the included studies. RESULTS: Most of the included studies showed that SNPs or genotypes of CYP that modify its metabolising activity have no effect on the occurrence, frequency or severity of vasomotor symptoms, including hot flashes. One study showed no correlation of these genetic variations in CYP with musculoskeletal symptoms, and no data were available on the association between such genetic variations and vaginal symptoms. CONCLUSIONS: Overall, genetic variations in CYP have no effect on the experience of hot flashes among breast cancer patients. We recommend exploration of the link between the active metabolites of chemotherapeutic drugs and the molecules shown to affect the occurrence or severity of hot flashes, and the establishment of the relationship between such genetic variations and patients' experience of musculoskeletal and vaginal symptoms. Subgroup analyses based on patients' duration of adjuvant endocrine therapies in such studies are recommended.

A Dance Program to Manage A Fatigue-Sleep Disturbance-Depression Symptom Cluster among Breast Cancer Patients Receiving Adjuvant Chemotherapy: A Feasibility Study.

OBJECTIVE: Fatigue, sleep disturbance, and depression (FSD) are highly prevalent among breast cancer (BC) patients undergoing adjuvant chemotherapy, constituting a common symptom cluster (i.e., FSD cluster). Exercise is effective in relieving fatigue, alleviating sleep disturbance, and improving the quality of life (QoL) during adjuvant chemotherapy among these women. Therefore, this study aimed to assess the feasibility and acceptability of a dance program with social support elements for managing this symptom cluster. METHODS: A prospective randomized controlled design combined with a semi-structured interview was utilized. Twenty consented eligible participants were randomly assigned to a dance group or an attention control group after baseline assessment but before chemotherapy. The feasibility of recruitment, retention, intervention, and data collection procedures and the acceptability of exercise modality, hospital-based instruction, and home-based practice were collected by retrieving information from research documents and interviews by the principal investigator 4 weeks after the start of intervention. RESULTS: The recruitment and retention rates were 86.96% and 100.00%, respectively. Participants took about 30-40 min to complete the questionnaire. All the items were comprehensible. The baseline characteristics were comparable between groups, indicating that randomization was successful. The implementation procedure progressed smoothly. Dancing was considered interesting and easy, and participants would like to practice at home. Only minor adjustments would be needed for future studies. CONCLUSIONS: This study demonstrated that the proposed dance program was feasible and acceptable for BC patients in hospital and home settings. A full-scale study is warranted to examine its effects on managing the FSD cluster and promoting QoL.

How patients with cancer experience dignity: An integrative review.

BACKGROUND: A diagnosis of cancer and its treatments can be associated with a prominent issue of loss of dignity or an undermined sense of dignity for patients. Research is increasingly being conducted into how patients with cancer experience dignity, with the aim to build clinical foundations for care that preserves patients' sense of dignity. AIM: This review summarises and synthesises the available empirical literature on the experience of dignity in patients with cancer regarding both the perception of dignity and associated factors. METHOD: An integrative review method was used. A literature search was conducted in 11 databases using the search terms 'dignity' OR 'existential' OR 'existentialism' combined with 'cancer'. The Mixed Methods Appraisal Tool (version 2011) was adopted to appraise the methodological quality of the included studies. RESULTS: Nine qualitative studies and 13 quantitative studies met the selection criteria and were included in the review. The ways that patients with cancer perceived dignity include autonomy/control, respect, self-worth, family connectedness, acceptance, hope/future and God/religious. Factors associated with dignity include demographics, physical and psychosocial distress, experiences of suffering and coping strategies. CONCLUSION: Dignity-conserving care should respect patients' human autonomy to strengthen their sense of self-worth, acceptance, hope, reinforce family connectedness, and foster coping strategies to control the physical, psychosocial factors and experience of sufferings that threaten their sense of dignity.
