RESUMO

BACKGROUND: Knowledge of predictors of cognitive frailty (CF) trajectories is required to develop preventive strategies to delay or reverse the progression from CF to dementia and other adverse outcomes. This 2-year prospective study aimed to investigate factors affecting the progression and improvement of CF in older Taiwanese adults. METHODS: In total, 832 community-dwelling people aged ≥ 65 years were eligible. Fried's five frailty criteria were used to measure prefrailty and frailty, while cognitive performance was assessed by the Clinical Dementia Rating and Mini-Mental State Examination. Each component of reversible CF and potentially reversible CF was assigned a score, with a total score ranging 0 to 5 points. Two annual follow-up CF assessments were conducted. The group-based trajectory model was applied to identify latent CF trajectory groups, and a multinomial logistic regression was used to examine relationships of explanatory variables with CF trajectories. RESULTS: According to data on 482 subjects who completed the two annual follow-ups, three CF trajectories of robust, improvement, and progression were identified. After adjusting for the baseline CF state, CF progression was significantly associated with an older age (odds ratio [OR] = 1.08; 95% confidence interval [CI], 1.02 ~ 1.14), a lower Tinetti balance score (OR = 0.72; 95% CI, 0.54 ~ 0.96), a slower gait (OR = 0.98; 95% CI, 0.97 ~ 0.99), and four or more comorbidities (OR = 2.65; 95% CI, 1.19 ~ 5.90), while CF improvement was not significantly associated with any variable except the baseline CF state. In contrast, without adjusting for the baseline CF state, CF progression was significantly associated with an older age, female sex, balance scores, gait velocity, regular exercise, the number of comorbidities, and depression, while CF improvement was significantly associated with female sex, balance scores, and the number of comorbidities. CONCLUSIONS: The baseline CF state, an older age, poorer balance, slower gait, and a high number of comorbidities may contribute to CF progression, while the baseline CF state may account for associations of engaging in regular exercise and depression with CF development.

RESUMO

PURPOSE: This study aimed to investigate whether the return to level I sports, concomitant injuries, foot-related problems, and other factors would increase the risk of knee reinjury after anterior cruciate ligament reconstruction (ACLR). METHODS: This study used a prospective cohort study design. Online enrolment from August 2018 to January 2019 in ACL Community Indonesia recruited 148 patients who had undergone ACLR less than one month prior to injury. Knee injury occurrence after ACLR was diagnosed through a physical examination and positive MRI or arthroscopic findings. RESULTS: During the study, 55 knee reinjuries occurred. The proportional hazards model analysis revealed that the risk of knee reinjury at 12 and 24 months for patients who returned to level I sports (hazards ratio (HR)=3.17 and HR=3.90, respectively) was significantly higher than that of the patients who did not return to sports and that the risk for those who returned to level II/III sports did not significantly increase at 12 or 24 months. Patients with concomitant meniscus injury had a significantly higher risk of knee reinjury at 12 and 24 months (HR=3.33 and HR=2.25, respectively) than those without, and the risk of knee reinjury for patients with concomitant posterior cruciate ligament injury was significantly higher at 12 months (HR=3.05) but not at 24 months. Fewer knee symptoms after ACLR were significantly associated with a lower risk of knee reinjury (HR=0.98) at 12 and 24 months. CONCLUSIONS: The return to level I sports, concomitant meniscus and posterior cruciate ligament injury, and knee symptoms after ACLR may increase the risk of knee reinjury for post-ACLR patients.

RESUMO

The prolyl hydroxylation of hypoxia-inducible factor 1α (HIF-1α) mediated by the EGLN-pVHL pathway represents a classic signalling mechanism that mediates cellular adaptation under hypoxia. Here we identify RIPK1, a known regulator of cell death mediated by tumour necrosis factor receptor 1 (TNFR1), as a target of EGLN1-pVHL. Prolyl hydroxylation of RIPK1 mediated by EGLN1 promotes the binding of RIPK1 with pVHL to suppress its activation under normoxic conditions. Prolonged hypoxia promotes the activation of RIPK1 kinase by modulating its proline hydroxylation, independent of the TNFα-TNFR1 pathway. As such, inhibiting proline hydroxylation of RIPK1 promotes RIPK1 activation to trigger cell death and inflammation. Hepatocyte-specific Vhl deficiency promoted RIPK1-dependent apoptosis to mediate liver pathology. Our findings illustrate a key role of the EGLN-pVHL pathway in suppressing RIPK1 activation under normoxic conditions to promote cell survival and a model by which hypoxia promotes RIPK1 activation through modulating its proline hydroxylation to mediate cell death and inflammation in human diseases, independent of TNFR1.

RESUMO

BACKGROUND: A randomized trial was conducted to investigate the effects of computerized cognitive training (CCT) and tai chi exercise (TCE) vs. health education (HE) on cognitive functions in 189 older adults with mild cognitive impairment (MCI). METHODS: Cognitive functions were assessed by the five-domain Mattis Dementia Rating Scale (MDRS) (attention, initiation/perseveration, construction, conceptualization, and memory) and the modified Telephone Interview of Cognitive Status (TICS-M), while the timed up and go (TUG), Tinetti's balance, activities of daily living (ADLs), and Activities-specific Balance Confidence (ABC) were also evaluated. Each intervention was delivered once a week for 6 months. All outcomes were followed up at 6 and 12 months of the study. RESULTS: Compared to HE, CCT increased scores on the MDRS's total, initiation/perseveration, construction, and conceptualization domains and on the TICS-M at 6 months and those on the MDRS's total, attention, construction, conceptualization, and memory domains and on the TICS-M at 12 months; TCE increased scores on the MDRS's total and construction domains and on the TICS-M at 6 months and those on the MDRS's total, attention, initiation/perseveration, and conceptualization domains and on the TICS-M at 12 months. Moreover, CCT improved the TUG at 6 and 12 months and Tinetti's balance at 12 months, and TCE improved the TUG at 6 and 12 months, Tinetti's balance, and ABC at 6 and 12 months, and ADLs at 12 months. CONCLUSIONS: The effects of CCT and TCE on improving global cognition and certain cognitive domains for older MCI adults may have been small but they lasted for at least 12 months.

RESUMO

BACKGROUND: Few studies emphasize on predictors of incident cognitive frailty (CF) and examine relationships between various gait characteristics and CF. Therefore, we conducted a 2-year prospective study to investigate potential predictors, including gait characteristics, of incident reversible CF (RCF) and potentially RCF (PRCF) among Taiwanese older adults. METHODS: Eligible participants were individuals aged ≥ 65 years, who could ambulate independently, and did not have RCF/PRCF at the baseline. The baseline assessment collected information on physical frailty and cognitive measures, in addition to sociodemographic and lifestyle characteristics, preexisting comorbidities and medications, gait characteristics, Tinetti's balance, balance confidence as assessed by Activities-specific Balance Confidence (ABC) scale, and the depressive status as assessed by the Geriatric Depression Scale. The Mini-Mental State Examination (MMSE), Mattis Dementia Rating Scale, and Digit Symbol Substitution Test were used to evaluate cognitive functions. Incident RCF and PRCF were ascertained at a 2-year follow-up assessment. RESULTS: Results of the multinomial logistic regression analysis showed that incident RCF was significantly associated with older age (odds ratio [OR] = 1.05) and lower ABC scores (OR = 0.97). Furthermore, incident PRCF was significantly associated with older age (OR = 1.07), lower ABC scores (OR = 0.96), the presence of depression (OR = 3.61), lower MMSE scores (OR = 0.83), slower gait velocity (OR = 0.97), and greater double-support time variability (OR = 1.09). CONCLUSIONS: Incident RCF was independently associated with older age and lower balance confidence while incident PRCF independently associated with older age, reduced global cognition, the presence of depression, slower gait velocity, and greater double-support time variability. Balance confidence was the only modifiable factor associated with both incident RCF and PRCF.

RESUMO

Exposure to high concentrations of copper can cause toxic effects on the growth and development of organisms, but the relevant toxic mechanisms are far from fully understood. This study investigated the changes of metabolites, genes, and gut microorganisms in earthworms (Eisenia fetida) exposed to 0 (control), 67.58 (low), 168.96 (medium), and 337.92 (high) mg/kg of Cu in soil for 60 days. Differentially expressed genes (DEGs) and differential metabolites (DMs) at the low-, medium-, and high-level Cu exposure groups were identified and introduced into Kyoto Encyclopedia of Genes and Genomes (KEGG) pathways. Integrated metabolomic and transcriptomic analysis revealed that amino acid metabolism, lipid metabolism, and carbohydrate metabolism are the major metabolic pathways disturbed by Cu exposure. Furthermore, Cu exposure significantly decreased the diversity of the intestinal bacterial community and affected the relative abundance (increased or decreased) of intestinal colonizing bacteria. This resulted in high energy expenditure, inhibited nutrient absorption and fatty acid synthesis, and weakened antioxidant and detoxification abilities, ultimately inhibiting the growth of E. fetida. These findings offer important clues and evidence for understanding the mechanism of Cu-induced growth and development toxicity in E. fetida and provide further data for risk assessment in terrestrial ecosystems.

RESUMO

Objective: To investigate the associations of specific cognitive functions and with the frailty trajectory among older Taiwanese adults.Methods: At baseline, 730 community-dwelling older adults were recruited from outpatient clinics of a general hospital. Frailty status was defined using phenotype criteria. Global cognition was assessed using the modified Telephone Interview of Cognitive Status and Mini-Mental State Examination (MMSE). The Mattis Dementia Rating Scale (MDRS) and Digit Symbol Substitution Test were used to evaluate 6 cognitive domains: attention, initiation/perseveration, construction, conceptualization, memory, and processing speed. The group-based trajectory model was used to identify latent frailty trajectory groups and the multinomial logistic regression was to examine the relationships of specific cognitive functions with frailty trajectory.Results: Among 485 participants (168 men, 317 women, and mean age: 71.1 ± 5.5 years) completed 2 annual follow-up assessments, three frailty trajectory groups of improvement, no-change, and progression were identified. After adjusting for baseline frailty status, age, sex, global cognition, regular exercise habit, and number of comorbidities, higher scores on MDRS's initiation/perseveration (odds ratio [OR] = 0.85; 95% CI = 0.75-0.95) and attention (OR = 0.63; 95% CI = 0.38-1.00), respectively, were significantly associated with lower risk of frailty progression. Conversely, no significant association was detected between MMSE or TICSM scores and frailty improvement or progression.Conclusion: Specific cognitive functions of initiation/perseveration and attention, rather than global cognition, may be more useful to predict frailty progression, thus allowing the identification of at-risk older adults.

RESUMO

AIM: This matched case-control study investigated potentially inappropriate medication (PIM) use, polypharmacy, and other potential risk factors for falls among hospitalized older adults in Taiwan. METHODS: During an 18-month study period, 131 case patients who experienced a fall during hospitalization in an acute-care hospital were identified and matched by the time of day, hospital ward, and age to controls (five for each case) who were selected through random systematic sampling. Data on demographics, medical characteristics, and all orally and intravascularly administered medications during hospitalization prior to a fall were collected. PIMs were assessed using the 2019 Beers criteria. RESULTS: A conditional logistic regression analysis revealed that admission to the departments of internal medicine (odds ratio [OR] = 2.33; 95% confidence interval [CI] = 1.09-4.91) and neurology and rehabilitation (OR = 4.67; 95% CI = 2.08-10.5), diabetes with end-organ damage (OR = 2.07; 95% CI = 1.11-3.86), PIM use of central nervous system drugs (OR = 1.81; 95% CI = 1.15-2.86), use of colchicine (OR = 5.49; 95% CI = 1.34-22.5) and spironolactone (OR = 4.54; 95% CI = 1.31-15.8) for renal function impairment, and polypharmacy (≥5 medications; OR = 1.81; 95% CI = 1.05-3.10) significantly increased the risk of falls. By contrast, being overweight or obese (OR = 0.47; 95% CI = 0.29-0.78) was associated with a significantly lower risk of falls. CONCLUSIONS: PIM use may increase the risk of falls in hospitalized older patients, and PIM identification and evaluation can reduce this risk. Geriatr Gerontol Int 2022; 22: 857-864.

RESUMO

INTRODUCTION: Violence against women remains a major public health concern in African countries. We conducted a matched case-control study to identify risk factors for recurrent violent injuries among African women in The Gambia, a small West African country. METHODS: During the 12-month study period, we recruited study participants from eight emergency departments in the metropolitan areas of the municipality of Kanifing and the West Coast region. We selected women aged ≥15 years who sought medical treatment for an injury due to physical violence at least twice over the study period. Two control groups were used: violence controls (VC), which included those who had experienced a single violence-related injury in the prior 12 months; and nonviolence controls (NVC), which included those who had experienced a nonviolent injury. Control patients were matched based on gender, health facility, injury date, and age (±2 years). RESULTS: In total, 116 case patients and 232 control patients participated in the study. Results of the conditional logistic regression analyses of the VC and NVC control groups individually showed that women with recurrent violent injuries had a significantly higher likelihood of having a secondary education (odds ratio [OR]VC 6.47; ORNVC 4.22), coming from a polygamous family (ORVC 3.81; ORNVC 3.53), and had been raised by a single parent (ORVC 5.25; ORNVC 5.04). Furthermore, compared with the VC group, women with recurrent violent injuries had a significantly higher likelihood of living in a rented house (ORVC 4.74), living with in-laws (ORVC 5.98), and of having experienced childhood abuse (ORVC 2.48). Compared with the NVC group, women with recurrent violent injuries had a significantly higher likelihood of living in an extended family compound (ORVC 4.77), having more than two female siblings (ORVC 4.07), and having been raised by a relative (ORVC 3.52). CONCLUSION: We identified risk factors for recurrent injuries from physical violence among African women in The Gambia. Intervention strategies targeting these risk factors could be effective in preventing recurrent violence against African women.

RESUMO

Kynurenic acid (KynA) is tissue protective in cardiac, cerebral, renal, and retinal ischemia models, but the mechanism is unknown. KynA can bind to multiple receptors, including the aryl hydrocarbon receptor, the a7 nicotinic acetylcholine receptor (a7nAChR), multiple ionotropic glutamate receptors, and the orphan G protein-coupled receptor GPR35. Here, we show that GPR35 activation was necessary and sufficient for ischemic protection by KynA. When bound by KynA, GPR35 activated Gi- and G12/13-coupled signaling and trafficked to the outer mitochondria membrane, where it bound, apparantly indirectly, to ATP synthase inhibitory factor subunit 1 (ATPIF1). Activated GPR35, in an ATPIF1-dependent and pertussis toxin-sensitive manner, induced ATP synthase dimerization, which prevented ATP loss upon ischemia. These findings provide a rationale for the development of specific GPR35 agonists for the treatment of ischemic diseases.

RESUMO

Copper is a trace element that necessary for plant growth in the soil. However, in recent years, due to human activities, the content of copper in soil exceeds the standard seriously, which is threatening the safety of soil animals, plants and even human beings. In this study, we investigated the effects and molecular mechanisms of 60 days long-term copper exposure on earthworms (Eisenia fetida) at 67.58 mg/kg, 168.96 mg/kg and 337.92 mg/kg concentration by using transcriptome and metabolomics. Transcriptome analysis showed that the expression of energy metabolism related genes (LDH, GYS, ATP6N, GAPDH, COX17), immune system related genes (E3.2.1.14) and detoxification related genes (UGT, CYP2U1, CYP1A1) were down-regulated, the expression of antioxidant system related genes (GCLC, HPGDS) were up-regulated in copper exposure experiment of earthworms. Similarly, metabolomics analysis revealed that the expression of energy metabolism related metabolites (Glucose-1-phosphate, Glucose-6-phosphate), TCA cycle related metabolites (fumaric acid, allantoic acid, malate, malic acid) were down-regulated, digestion and immune system related metabolites (Trehalose-6-phosphate) were up-regulated. Integrating transcriptome and metabolomics data, it was found that higher antioxidant capacity and accelerated TCA cycle metabolism may be an adaptive strategy for earthworms to adapt to long-term copper stress. Collectively, the results of this study will greatly contribute to incrementally understand the stress responses on copper exposure to earthworms and supply molecular level support for evaluating the environmental effects of copper on soil organisms.

RESUMO

ABSTRACT: Adhitya, IPGS, Yu, W-Y, Bass, P, Kinandana, GP, and Lin, M-R. Effects of Kinesio taping and transcutaneous electrical nerve stimulation combined with active stretching on hamstring flexibility. J Strength Cond Res 36(11): 3087-3092, 2022-Active stretching (AS), Kinesio taping (KT), and transcutaneous electrical nerve stimulation (TENS) are frequently used to ameliorate pain and improve the ranges of motion (ROM) of athletes; however, the effectiveness of KT and TENS combined with AS in ameliorating short hamstring syndrome is yet to be determined. In this single-blinded randomized trial, 135 male soccer players with bilateral short hamstring syndrome were assigned to 3 intervention groups-AS, KT + AS, and TENS + AS-through block randomization. Each subject received the intervention twice per week for 4 weeks. The ROM of both legs was assessed through passive knee extension and straight leg raising tests at baseline and the end of the intervention. After the 4-week intervention, significant ROM changes in both legs were detected in the AS (9.5°-18.4°), KT + AS (14.9°-22.4°), and TENS + AS (14.9°-22.3°) groups. Compared with the AS group, both the KT + AS (3.8°-5.7°) and TENS + AS (3.9°-5.7°) groups showed significantly increased ROM in both legs over the intervention period, and no significant differences were observed in ROM changes between the KT + AS and TENS + AS groups. In conclusion, both KT and TENS in combination with AS may increase ROM more than AS alone, and the improvements obtained using KT with AS and TENS with AS may be similar.

RESUMO

OBJECTIVE: To investigate differences between older men and women in Taiwan in personal and situational risk factors for sustaining a traumatic brain injury (TBI) versus soft-tissue injury (STI) due to a fall. DESIGN: Matched case-control study. PARTICIPANTS AND SETTINGS: Cases were defined as patients with a primary diagnosis of TBI due to a fall and were identified from those 60 years or older who visited the emergency department (ED) of 3 university-affiliated hospitals in 2015. Matched by the same hospital ED, gender, and time of falling, 3 controls who had no TBI and who had sustained only soft-tissue injury (STI) due to falling were selected for comparison with each case. Personal factors and situational exposures were compared between the control and case groups. In total, 96 cases and 288 controls in men and 72 cases and 216 controls in women participated in this study. MAIN MEASURES: Personal factors (sociodemographic and lifestyle factors, medical characteristics, and functional abilities) and situational exposures (location, activities before the fall, center-of-mass change, type of fall, falling direction, protective response, and impact during the fall). RESULTS: In men, after adjusting for other variables, older age (odds ratio [OR] = 1.04), regular alcohol use (OR = 2.03), an indoor fall (OR = 1.92), activity of getting in/out of bed (OR = 2.56), a fall due to dizziness (OR = 4.09), and falling backward (OR = 2.95) were independently associated with a higher odds of TBI. In women, an older age (OR = 1.03), the presence of Parkinson disease (OR = 10.4), activities of toileting (OR = 2.50), getting in/out of bed (OR = 4.90), and negotiating stairs (OR = 7.13), a fall due to dizziness (OR = 5.05), and falling backward (OR = 2.61) were independently associated with a higher odds of TBI. CONCLUSIONS: Our results demonstrated similarities and differences in personal and situational risk factors for fall-related TBIs versus STIs between older men and women, and gender differences should be considered when developing intervention strategies.

RESUMO

BACKGROUND: Circular RNAs (CircRNAs) feature prominently in the progression of various cancers. However, the biological functions of many circRNAs in hepatocellular carcinoma (HCC) are far from fully clarified. This work is performed to decipher the function of circ_0000098 (circSLC30A7) in modulating the progression of HCC and its molecular mechanism. METHODS: Microarray data (GSE97332) were available from the Gene Expression Omnibus (GEO) database, and circRNA differentially expressed in HCC tissues was screened out by GEO2R tool. Circ_0000098, microRNA-1204 (miR-1204), and aristaless-like homeobox-4 (ALX4) mRNA expressions were detected by quantitative real-time polymerase chain reaction (qRT-PCR). Cell counting kit-8 (CCK-8), scratch wound healing, and Transwell assays were adopted to determine proliferation, migration, and invasion of HCC cells. ALX4 protein, E-cadherin, N-cadherin, and Vimentin expressions were evaluated by Western blot. In addition, the targeting relationship between miR-1204 and circ_0000098 or ALX4 was studied with dual-luciferase reporter assay and RIP assay. RESULTS: Circ_0000098 expression level was markedly declined in HCC tissues and cells, and its underexpression was associated with larger tumor size of HCC patients. Knocking down circ_0000098 observably promoted the multiplication, migration, invasion, and epithelial-mesenchymal transition (EMT) of Huh7 and SMMC-7721 cells. Additionally, circ_0000098 was mainly distributed in the cytoplasm of HCC cells, and up-regulated ALX4 expression through competitively decoying miR-1204. CONCLUSION: Circ_0000098, as a competitive endogenous RNA (ceRNA) of miR-1204, upregulates ALX4 expression and suppresses the growth, migration, invasion, and EMT of HCC cells.

RESUMO

BACKGROUND: This study aimed to examine the psychometric performance of the Foot and Ankle Outcome Score (FAOS) used in Indonesian patients with chronic lateral ankle instability (CLAI). METHODS: The FAOS was translated into Indonesian through standardized procedures. Among 224 patients with unilateral CLAI recruited from 14 physical therapy clinics during a 1-year period, reliabilities, construct validities, and responsiveness levels of the FAOS were examined. Active and passive range of motion of ankle dorsiflexion or plantiflexion, figure-of-eight, numeric pain rating scale (NPRS), and Short Form (SF)-36 were used to test the construct validities. RESULTS: The five subscales indicated adequate internal consistency (Cronbach's alpha, 0.74 ~ 0.96) and interrater test-retest reliabilities (interclass correlation coefficients, 0.80 ~ 0.94). Subscales of the FAOS moderately converged with those selected measures with similar constructs ([Formula: see text] values, 0.32 ~ 0.53), with the exception of the correlation of pain with the NPRS ([Formula: see text], -0.06). Results of the principal component analysis showed that the five-factor structure of the FAOS was appropriate for the Indonesian data, although six items (four in the pain and two in the other symptoms (OSs) subscales) did not perfectly fit their original subscales. Guyatt's responsiveness index for the FAOS's subscales changed in the SF-36's physical function over a 1-month period and ranged 0.37 to 1.27. CONCLUSIONS: The Indonesian version of the FAOS demonstrated acceptable reliabilities and responsiveness, and fair construct validities among CLAI patients, although certain items in the pain and OSs subscales may need to be further explored and improved.

RESUMO

BACKGROUND: Situational factors during a fall among three common types of fractures of the distal forearm, hip, and vertebrae among older women in Taiwan were investigated. METHODS: In 2016 ~ 2017, study participants were identified from those aged ≥65 years who visited emergency departments due to a fall in two university-affiliated hospitals in Taipei. In addition to individual characteristics, situational factors during the fall (location, activity, change of center of mass, fall mode, fall direction, initiating a protective response, and being hit) were collected. A sample of 203 distal-forearm fractures, 189 vertebral fractures, and 375 hip fractures was recruited, while 717 women with a soft-tissue injury were used as a control group. The identification of situational risk factors for each type of fracture was validated by using those who sustained one of the other two types of fracture as a control group. RESULTS: After adjusting for age and other individual characteristics, compared to soft-tissue injuries, distal-forearm fractures were significantly more likely to occur with slips (odds ratio [OR] = 11.0; 95% confidence interval [CI] = 4.76 ~ 25.4), trips (OR = 3.40; 95% CI = 1.42 ~ 8.17), step-downs (OR = 4.95; 95% CI = 2.15 ~ 11.4), and from sideways falls (OR = 1.73; 95% CI = 1.12 ~ 2.67) and significantly less likely to occur indoors (OR = 0.62; 95% CI = 0.42 ~ 0.90) or from backwards falls (OR = 0.62; 95% CI = 0.41 ~ 0.95). Hip fractures were significantly more likely to occur with step-downs (OR = 1.76; 95% CI = 1.13 ~ 2.75) and from backwards (OR = 3.16; 95% CI = 2.15 ~ 4.64) or sideways falls (OR = 5.56; 95% CI = 3.67 ~ 8.41) and significantly less likely when hitting an object (OR = 0.26; 95% CI = 0.13 ~ 0.52) or initiating a protective response (OR = 0.58; 95% CI = 0.36 ~ 0.93). Vertebral fractures were significantly more likely to occur with slips (OR = 2.42; 95% CI = 1.30 ~ 4.50), step-downs (OR = 2.53; 95% CI = 1.43 ~ 4.48), and backwards falls (OR = 2.15; 95% CI = 1.39 ~ 3.32). Similar results were found in the validation analyses. CONCLUSIONS: Large variations in situational risk factors for the three types of fracture in older women existed. A combination of individual and situational risk factors may display a more-comprehensive risk profile for the three types of fracture, and an intervention that adds training programs on safe landing strategies and effective compensatory reactions may be valuable in preventing serious injuries due to a fall.

RESUMO

The effect of spatial cueing on eye gaze has been confirmed by a large number of studies, but the effect of spatial cueing on face direction and the impact of eye gaze on this effect are less known. In four experiments, we investigated the attentional bias induced by face direction. A modified paradigm of spatial cueing was adopted with stimuli that were static faces rotated by 90 or 45° to the left or right from the frontal view. To control the effect of eyes, face stimuli with eyes open and those with eyes closed were both used in each experiment. In Experiment 1, the facial cue (face rotated by 90°) and target were presented simultaneously, and the stimulus onset asynchrony (SOA) between the facial cue and target was set to be 300, 600, and 900 ms in Experiments 2 (face rotated by 90°), 3 (inverted face rotated by 90°), and 4 (face rotated by 45°), respectively. The response time of detecting the target position was recorded. The spatial cueing effects were nonsignificant in Experiment 1, in which the cue and target were presented simultaneously. However, significant spatial cueing effects of face direction were found in Experiments 2 and 3, in which the upright and inverted faces rotated by 90° were adopted, respectively, in both the eyes open and eyes closed conditions. In addition, we did not find an effect of spatial cueing with the face rotated by 45° (Experiment 4). Our results indicate that face direction can bias visual attention. This effect might not be based on the holistic processing of faces.

RESUMO

BACKGROUND: Physical violence against women is a major public health problem in African countries; however, no studies have focused on factors associated with violent injuries to women in Africa. OBJECTIVES: A matched case-control study was conducted to investigate risk factors for injuries from physical violence against African women in The Gambia. METHODS: Over a 12-month study period, study participants were recruited from emergency departments of eight government-managed health care facilities. Cases were female patients aged ≥ 15 years who had been violently injured. Matched by the health facility, date of injury, sex, and age, a control patient for each case was selected from those injured due to nonviolent mechanisms. RESULTS: In total, 194 case-control pairs were recruited. Results of a conditional logistic regression showed that being a Fula (odds ratio [OR] 2.45; 95% confidence interval [CI] 1.06-5.66), living in an extended family compound (OR 3.07; 95% CI 1.22-7.72), having six or more female siblings (OR 3.10; 95% CI 1.38-6.97), having been raised by grandparents (OR 3.34; 95% CI 1.06-10.51), and having been verbally (OR 3.04; 95% CI 1.56-5.96) or physically abused (OR 3.36; 95% CI 1.34-8.39) in the past 12 months were significantly associated with injury from physical violence. CONCLUSION: Most risk factors identified for violent injury among African women are unique to the studied geography. Violence prevention programs, if designed based on these identified risk factors, may be more effective for this population.

RESUMO

OBJECTIVE: To compare the effects of computerized cognitive training (CCT) and tai chi (TC) with usual care (UC) on cognitive functions and secondary outcomes in older adults with traumatic brain injury. PARTICIPANTS AND SETTINGS: Ninety-six patients aged 55 years and older who had a diagnosis of traumatic brain injury requiring hospital admission. DESIGN: Randomized controlled trial. MAIN MEASURES: The Mattis Dementia Rating Scale (MDRS), Mini-Mental State Examination, modified Telephone Interview of Cognitive Status, and Trail Making Tests A and B. RESULTS: Compared with UC, CCT increased scores on the MDRS's total, attention, and memory and those on the Mini-Mental State Examination and Telephone Interview of Cognitive Status over the 6-month intervention; TC increased scores on the MDRS's total and conceptualization and those on the Mini-Mental State Examination over the 6-month intervention, while it also increased scores on the MDRS's total and initiation/preservation and those on the Telephone Interview of Cognitive Status and reduced the time to complete the Trail Making Test B over the 12-month study. Furthermore, compared with UC, CCT increased handgrip strength and TC reduced the time to complete 5 sit-to-stands over the 6-month intervention. CONCLUSION: Both CCT and TC may improve global cognition and different specific cognitive domains in older traumatic brain injury patients; the TC's effect may last for at least an additional 6 months.

RESUMO

An efficient and green aqueous-solid system was introduced for phospholipase D-mediated transphosphatidylation. γ-(2,3-epoxypropoxy) propytrimethoxysilane was covalently bound to silica and esterified by acetic acid, which acted as an anchor molecule to facilitate the adsorption of phosphatidylcholine (PC) in aqueous solutions. Obtained silica-adsorbed PC was successfully used for transphosphatidylation to produce phosphatidylserine (PS). The PC loading and PS yield reached 98.8 and 98.3%, respectively. A new model was proposed to illustrate the adsorption and enzymatic processes. Moreover, this aqueous-solid system provides a promising way for the continuous production. Four kinds of phospholipids were biosynthesized in the pack-bed reactor. The stability of the aqueous-solid system was excellent, as demonstrated by its use 30 times without any loss of the productivity. The product was eluted by coconut oil and manufactured into microcapsules. Toxic agents were completely avoided in the whole production process.
