RESUMEN
This study aimed to evaluate the association between the questionnaires SARC-F and SARC-CalF with risk of mortality in patients undergoing hemodialysis (HD). A cohort study, with patients on HD age ≥ 18 years, both sex, between June 2019 and April 2023. Body composition (anthropometry and bioelectrical impedance), muscle functional (handgrip strength and gait speed), screening of sarcopenia using the SARC-F and SARC-CalF, nutritional status and laboratory data were assessed. Follow-up for mortality up to 47 months. The sample consisted of 243 participants and the prevalence of risk of sarcopenia using SARC-F and SARC-CalF were 30% and 45%, respectively; 65 died for all reasons and three patients were censored due to transplantation. Multivariate analysis identified SARC-CalF as predictor of mortality in HD patients [hazard ratio 1.96; 95% CI (1.01-3.79); p = 0.04]. The survival analysis showed that there was a significant difference in the survival curves among the groups stratified by SARC-F and SARC-CalF for log-rank test. A higher specificity was found for SARC-CalF than SARC-F (80% vs. 77%) in receiver operating characteristic (ROC) curve. Both questionnaires were associated with anthropometric, parameters of body composition, physical measurements, and SARC-CalF was predictor of risk for mortality in HD patients.

BACKGROUND: Respiratory sarcopenia is characterized by the weakness of respiratory muscles associated with sarcopenia due to aging or systemic diseases such as chronic kidney disease (CKD). Patients with CKD undergoing dialysis are particularly susceptible to respiratory muscle weakness caused by factors such as fluid overload and electrolyte imbalance. This weakness not only affects ventilation but also impairs oxygen uptake and delivery to muscle tissue, potentially leading to severe sarcopenia. Thus, the objective of this study is to conduct a respiratory sarcopenia screening in patients with CKD undergoing haemodialysis (HD) and peritoneal dialysis (PD). METHODS: This is an observational, cross-sectional and multicentre study conducted between March 2023 and March 2025. The study was approved by the Research Ethics Committee at two centres. Sarcopenia diagnosis is determined based on low handgrip strength and amount of appendicular skeletal muscle mass, assessed through bioelectrical impedance analysis. Respiratory sarcopenia is diagnosed in patients with sarcopenia who have low inspiratory muscle strength, evaluated through a manovacuometry test. The severity of sarcopenia and respiratory sarcopenia is defined, respectively, by low physical performance (measured using the Short Physical Performance Battery and Timed-Up and Go test) and pulmonary performance (measured through spirometry). Thus, this study will include 81 patients undergoing dialysis (41 on HD and 40 on PD) from three participating centres. DISCUSSION: The literature has been focused on respiratory function in CKD; however, the relationship with sarcopenia remains understudied. We believe that, similar to appendicular skeleton muscles, the axial skeleton muscles are also likely to weaken with the presence of chronic disease, such as CKD.

In the present work, composites with non-toxic metal oxides, such as TiO2 and ZnO, and a natural red clay (taua) reach in hematite were used in the photocatalytic degradation of Fenthion. The composite TiO2/Taua (0.5:1â wt. ratio) and pure TiO2 were prepared by sol-gel method while ZnO/Taua (0.5:1â wt. ratio) and pure ZnO were prepared by Pechini method. The materials were characterized by XRD, SEM, EDX, and DRS. The anatase phase was formed in both pure TiO2 and TiO2/Taua, while the hexagonal phase was formed in pure ZnO and ZnO/Taua. The bandgap energies for the two composites were narrowed compared to the respective pure oxides as consequence of the hematite (α-Fe2O3, Eg = 2.1â eV) in the red clay, reaching 2.1â eV for TiO2/Taua and 2.0â eV for ZnO/Taua, while the bandgap energies for pure TiO2 and ZnO were 3.2 and 3.0â eV, respectively. Fenthion was not degraded in the dark, but the concentration droped 20% after 180 min under visible light irradiation without photocatalyst and 60% after 210â min in the presence of the pure red clay. Both TiO2/Taua and ZnO/Taua composites were also photocatalytic active to degrade Fenthion (λ > 420â nm), with degradation of 78% (in 180â min) and 85% (in 210â min) respectively. In the optimized conditions (pH 2, 100â mgâ L-1 of H2O2 and 30â mgâ L-1 of Fenthion), the ZnO/Taua composite was the most efficient, reaching 89% degradation in up to 30â min, with Fenthion sulfoxide as the degradation product.

Association between cognitive impairment and gait performance occurs in mild cognitive impairment (MCI) and Alzheimer's disease (AD), particularly under "divided attention" conditions, leading to a greater risk of falls. We studied 36 controls, 42 MCI, and 26 mild AD patients, using the Timed Up-and-Go test (TUG) under four conditions: TUG single - TUG1; TUG cognitive - TUG2; TUG manual -TUG3; TUG cognitive and manual - TUG4. Cognition was assessed using the MMSE, SKT, Exit25, and TMT (A and B). We found significant correlations between cognitive scores and TUG2 [r values (MMSE: -0.383, TMT-A: 0.430, TMT-B: 0.386, Exit25: 0.455, SKT: 0.563)] and TUG4 [(MMSE: -0.398, TMT-A: 0.384, TMT-B: 0.352,Exit25: 0.466, SKT: 0.525)] in the AD group, and between all TUG modalities and SKT in MCI and AD. Our results revealed that functional mobility impairment in cognitive dual tasks correlated to cognitive decline in AD patients and to attention and memory impairment in MCI.

OBJECTIVES: Identify barriers and strategies for implementation of the protocol for managing tuberculosis/ human immunodeficiency virus (TB/HIV) coinfection in specialized care services in Ceará state, through evaluation research. METHODS: The study followed iPIER methodology, a new initiative to help improve the implementation of health programs through the use of research that is conducted as a part of the implementation process. Data were collected on the structure and processes of 22 services and barriers were explored in four focus groups with 28 participants, from the standpoint of the health team, administrators, and users. The discussions were transcribed and interpreted with regard to the objectives of the study. RESULTS: The information on structure and process revealed that six services manage TB/HIV coinfection and 16 do not. The barriers were: team members were unaware of the protocol; lack of clinical practice guidelines in the services; specialized care services working at all three levels of the health system; inadequate spaces for treatment of airborne diseases; and lack of communication with primary health care sectors for patient transfers. The results were discussed with teams and administrators in seminars held in the services and with program managers for sexually transmitted infections, human immunodeficiency virus, AIDS, hepatitis, and tuberculosis. CONCLUSIONS: Direct dialogue between administrators, implementers, users, and researchers generated knowledge about the services and led to joint preparation of modifications in workflow aimed at acceptance and use of the protocol; however, users continue to resist adherence to treatment.

OBJETIVOS: Avaliar e comparar a percepção da funcionalidade de idosos com doença de Alzheimer (DA) em relação à percepção de seus cuidadores, bem como avaliar e comparar essa relação de acordo com o grau de comprometimento cognitivo desses idosos. MÉTODOS: Foi realizado estudo transversal em 20 idosos com DA e seus cuidadores, sendo aplicada a Medida de Independência Funcional (MIF) para avaliar a percepção da funcionalidade de acordo com o relato do idoso com DA e seu cuidador; foi aplicada a escala de avaliação clínica da demência (CDR) para avaliar o estadiamento clínico da demência, sendo considerados idosos com DA leve (CDR 1) e DA moderada (CDR 2). RESULTADOS: Comparada a percepção da funcionalidade da amostra total de idosos com DA e seus respectivos cuidadores, a média da MIF foi de 116,5 (dp=9,8) pontos, segundo a visão dos idosos, e a média foi de 88,5 (dp=19,0) pontos nas tarefas avaliadas pela MIF, de acordo com seus cuidadores (p<0,001). O mesmo padrão foi observado na comparação entre os idosos com DA leve e seus cuidadores, embora os itens "autocuidados" e "mobilidade da MIF" não tenham sido estatisticamente significativos. Já nos idosos com DA moderada, houve diferença significativa em todas as dimensões da MIF quando comparada a seus cuidadores. CONCLUSÃO: Idosos com DA subestimam suas dificuldades quando comparados com a percepção de seus cuidadores e, à medida que a gravidade da doença aumenta, há piora progressiva da percepção da sua funcionalidade.
OBJECTIVES: Evaluate and compare of the perception of functionality in elderly with Alzheimer´s disease (AD) with the functionality they present according with the perception of their caregivers, as well as evaluate this relationship according to the degree of cognitive problems in this population METHODS: Cross-sectional study in 20 older people with AD and their caregivers, applying the Functional Independence Measures (FIM) to evaluate the perception of functionality according to the report of the elderly with AD and their caregiver; it was used the Clinical Dementia Rating Scale (CDR) to evaluate the clinical staging of the dementia, considering elderly with mild AD (CDR 1) and moderate AD (CDR 2). RESULTS: When comparing the perception of the functionality of the total sample of older person with AD and their caregivers, the mean of FIM was 116.5 (sd=9.8) points, reported by patients with AD, and mean of 88.5 (sd=19.0) points according to their caregivers (p<0.001). The same pattern was observed in the comparison between the elderly with mild AD and their caregivers, although self-care and mobility FIM's items have not been statistically significant. In the elderly with moderate AD, there were significant differences in all dimensions of the FIM, when compared to their caregivers. CONCLUSION: Older patients with AD underestimate their difficulties as compared to the perception of their caregivers and this perception of functionality is worse according with progression of AD.

Motor disorders may occur in mild cognitive impairment (MCI) and at early stages of Alzheimer's disease (AD), particularly under divided attention conditions. We examined functional mobility in 104 older adults (42 with MCI, 26 with mild AD, and 36 cognitively healthy) using the Timed Up and Go test (TUG) under 4 experimental conditions: TUG single task, TUG plus a cognitive task, TUG plus a manual task, and TUG plus a cognitive and a manual task. Statistically significant differences in mean time of execution were found in all four experimental conditions when comparing MCI and controls (p < .001), and when comparing MCI and AD patients (p < .05). Receiver-operating characteristic curve analyses showed that all four testing conditions could differentiate the three groups (area under the curve > .8, p < .001 for MCI vs. controls; area under the curve > .7, p < .001 for MCI vs. AD). The authors conclude that functional motor deficits occurring in MCI can be assessed by the TUG test, in single or dual task modality.

Cognitive impairment and fear of falling are risk factors for falls in older adults. Recurrent falls are more prevalent in older adults with cognitive impairment. We examined the number of previous falls, self-reported fear of falling, and the Falls Efficacy Scale-International (FES-I) in 104 older adults [26 with mild Alzheimer's disease (AD), 42 with mild cognitive impairment (MCI) and 36 cognitively healthy]. Older adults with AD and MCI had a higher number of falls (1.1 ± 1.2 and 1.5 ± 1.5, respectively) compared to the control group (0.3 ± 0.5, P < .001). Older adults with MCI more often reported fear of falling (74%) than patients with AD (31%) (P ≤ .002) and scored higher on the FES-I (29.7 and 23.8, respectively, P ≤ .01). The prevalence of falls in older adults with MCI and AD is higher than in subjects cognitively healthy. Older adults with MCI and AD differ in terms of reported fear of falling and falls self-efficacy.

The aim of this research was to evaluate the fractions obtained from the leaf, stem and roots of Allamanda schottii Pohl, Apocynaceae, responsible for the cytotoxicity, using several cell lines. Cytotoxicity was correlated with the season the part of the plant, and the major compounds were assessed. The ethanol extracts of leaves, stems and roots obtained at different seasons were evaluated in the human erythromyeloblastoid leukemia cell line (K562). Subsequently the ethanol extracts and dichloromethane fractions collected in winter were evaluated in mouse fibroblast cell line (Mus musculus) (L929), cervix adenocarcinoma (HeLa), human pre-B leukemia (Nalm6), as well as K562 cell line. The compounds plumericin, plumieride and ursolic acid isolated from ethanol extracts of the stems were evaluated in the same cell lines, as well as on breast adenocarcinoma cell line (MCF-7), and Mus musculus skin melanoma cell line (B16F10). The chromatographic profiles of the dichloromethane fractions were obtained by high performance liquid chromatography. The results revealed that the season during which A. schottii was collected, and the part of the plant analyzed, influence the cytotoxicity on the K562 cells tested. On the other hand the dichloromethane fractions, mainly from the stems and roots, are responsible for the cytoxicity on the cells tested. These results may be associated with the seasonal variation of plumericin in these parts of the plant. This information is in accordance with the HPLC analysis. The results clearly show the potential for the phytotherapeutic use of this species, and suggest that the cytotoxic activity observed may be due to the presence of plumericin, or to minor compounds not yet identified. The seasonal influence on the production of secondary metabolites was verified.
RESUMEN
Paracoccidioidomycosis (PCM) is a systemic mycosis endemic to Latin America. Brazil accounts for approximately 80% of cases, where it represents a major public health issue due to its disabling impact and the number of premature deaths it causes. We present a retrospective cohort study that was conducted in order to better understand factors that relate to cure of the infection in the treatment of 200 patients with PCM. We evaluated the influence of sociodemographic and clinical factors as well as therapeutic regimen (trimethoprim-sulfamethoxazole [TMP-SMX] and itraconazole) on the progress of PCM (cure and noncure). There was a higher incidence of cure (83%) among patients who regularly received treatment for their infections and completed the treatment protocol. Moreover, itraconazole (86.4%) was significantly superior to TMP-SMX (51.3%) in terms of cure rate and had a median treatment period that was significantly shorter (12 months) than that for TMP-SMX (23 months). A Cox proportional hazard regression model showed that use of itraconazole increased the hazard of cure, regardless of sex, age, education, clinical form, completion of treatment, and regularity. Although the results of this study show that itraconazole was the best treatment option for PCM patients, a double-blind, randomized, controlled trial is necessary to confirm this conclusion.

OBJECTIVE: To evaluate the effects of a multidisciplinary rehabilitation program on cognition, quality of life, and neuropsychiatry symptoms in patients with mild Alzheimer's disease. METHOD: The present study was a single-blind, controlled study that was conducted at a university-based day-hospital memory facility. The study included 25 Alzheimer's patients and their caregivers and involved a 12-week stimulation and psychoeducational program. The comparison group consisted of 16 Alzheimer's patients in waiting lists for future intervention. INTERVENTION: Group sessions were provided by a multiprofessional team and included memory training, computer-assisted cognitive stimulation, expressive activities (painting, verbal expression, writing), physiotherapy, and physical training. Treatment was administered twice a week during 6.5-h gatherings. MEASUREMENTS: The assessment battery comprised the following tests: Mini-Mental State Examination, Short Cognitive Test, Quality of Life in Alzheimer's disease, Neuropsychiatric Inventory, and Geriatric Depression Scale. Test scores were evaluated at baseline and the end of the study by raters who were blinded to the group assignments. RESULTS: Measurements of global cognitive function and performance on attention tasks indicated that patients in the experimental group remained stable, whereas controls displayed mild but significant worsening. The intervention was associated with reduced depression symptoms for patients and caregivers and decreased neuropsychiatric symptoms in Alzheimer's subjects. The treatment was also beneficial for the patients' quality of life. CONCLUSION: This multimodal rehabilitation program was associated with cognitive stability and significant improvements in the quality of life for Alzheimer's patients. We also observed a significant decrease in depressive symptoms and caregiver burden. These results support the notion that structured nonpharmacological interventions can yield adjunct and clinically relevant benefits in dementia treatment.
