3D-printed orthoses and prostheses for people with physical disability in rehabilitation centers: a scoping review.

AIMS: The World Health Organization points out that, by 2030, two billion people will need at least one assistive product. 3D printing can be used to meet the demands when dispensing these products. PURPOSE: This review aims to map the use of 3D printing in the manufacture of orthoses and prostheses for people with physical disability at rehabilitation centers. METHODS: Publications that deal with the use of 3D printing for the manufacture of orthoses and prostheses were used, preferably studies from 2012 to 2022. RESULTS: The majority of studies, 56.25%, were quantitative and 46.25% were evaluative research. None of the studies were characterized as developed at rehabilitation centers. 75% of them had the participation of people with physical disability. The use of 3D printing was, for the most part, for the development of assistive technologies for the upper limbs at 56.25%, while 31.25% were for the lower limbs. CONCLUSION: The assistive products developed were orthoses and prostheses for the wrist, hands, fingers, upper limbs, writing devices, sockets, knees, and feet. Although there were positive results in their performance, some limitations related to strength, stiffness, and resistance were observed.

Variation in a Darwin Wasp (Hymenoptera: Ichneumonidae) Community along an Elevation Gradient in a Tropical Biodiversity Hotspot: Implications for Ecology and Conservation.

Understanding how biodiversity varies from place to place is a fundamental goal of ecology and an important tool for halting biodiversity loss. Parasitic wasps (Hymenoptera) are a diverse and functionally important animal group, but spatial variation in their diversity is poorly understood. We survey a community of parasitic wasps (Ichneumonidae: Pimplinae) using Malaise traps up a mountain in the Brazilian Atlantic Rainforest, and relate the catch to biotic and abiotic habitat characteristics. We find high species richness compared with previous similar studies, with abundance, richness, and diversity peaking at low to intermediate elevation. There is a marked change in community composition with elevation. Habitat factors strongly correlated with elevation also strongly predict changes in the pimpline community, including temperature as well as the density of bamboo, lianas, epiphytes, small trees, and herbs. These results identify several possible surrogates of pimpline communities in tropical forests, which could be used as a tool in conservation. They also contribute to the growing evidence for a typical latitudinal gradient in ichneumonid species richness, and suggest that low to medium elevations in tropical regions will sometimes conserve the greatest number of species locally, but to conserve maximal biodiversity, a wider range of elevations should also be targeted.

The Effect of Pretreatments on the Physical Properties and Starch Structure of Potato Chips Dried by Microwaves under Vacuum.

Native potato starch has a semi-crystalline structure associated with a low glycemic index. Microwave vacuum drying (MWVD) produces crispy snacks under mild temperatures, reducing starch structural changes. However, blanching pretreatment gelatinizes starch, reducing crystallinity. A promising alternative is drying raw or blanched-then-cooled potatoes by MWVD. Cooling the blanched potato before MWVD aims to promote the partial return of the crystalline structure. Thus, this study evaluated how different pretreatments affect potato chips' starch structure and physical properties. Three samples were dried by MWVD: (i) raw (MWVD-RW), (ii) blanched (MWVD-BL), and (iii) blanched followed by cooling (4 °C for 48 h) (MWVD-BLC) potatoes. MWVD-RW samples presented a higher starch crystallinity (16.9%), which disappeared in MWVD-BL samples and partially returned in MWVD-BLC (8.7%). MWVD-BL and MWVD-BLC samples presented lower bulk (<0.338 g cm−3) density and higher porosity (>74%) and crispness. On the other hand, MWVD-BLC samples presented intermediate characteristics for color, true density, and porous distribution compared to others. All samples showed high porosity (>69%) and crispy texture. Therefore, based on the quality assessment, the MWVD-RW and MWVD-BLC produced healthy and crispy oil-free chips with a potentially lower glycemic index.

G protein-coupled oestrogen receptor stimulation ameliorates iron- and ovariectomy-induced memory impairments through the cAMP/PKA/CREB signalling pathway.

Iron accumulation in the brain has been associated with neurodegenerative disorders, and imaging studies in humans indicate that iron content in brain regions correlates with poor performance in cognitive tasks. In rats, iron overload impairs memory retention in a variety of memory tasks. Although the effects of iron on cognition in rodents are extensively reported, no previous study has been conducted in female rats. The incidence of certain dementias, such as Alzheimer's disease, is higher in women after menopause compared to aged-matched men. The role of oestrogen depletion in memory deficits in menopausal women is still a matter of debate. The present study aimed to characterise the effects of iron overload on memory in female rats by investigating the effects of ovariectomy (OVX, an experimental model of oestrogen depletion) in rats submitted to iron overload, as well as examining the effects of G protein-coupled oestrogen receptor (GPER) agonism on memory impairments induced by iron and OVX. Female rats received iron (30 mg kg-1 , orally) or vehicle at postnatal days 12-14 and were submitted to OVX in adulthood. Results showed that either iron or OVX impaired memory for object placement and inhibitory avoidance. The selective GPER agonist G1, administered immediately after training, reversed both iron- and OVX-induced memory impairments. G1 effects were abolished by protein kinase A (PKA) inhibition, suggesting the involvement of the cAMP/PKA/CREB signalling pathway. The search for novel oestrogen agonists with positive effects on cognition may be promising for the development of treatments for memory disorders.

Satisfaction with care in a Brazilian psychiatric inpatient unit: differences in perceptions among patients according to type of health insurance.

INTRODUCTION: User satisfaction assessment in mental health services is an important indicator of treatment quality. The objective of this study was to evaluate treatment satisfaction in a sample of inpatients with mental disorders and the associations between levels of satisfaction and clinical/sociodemographic variables. METHODS: This exploratory study investigated 227 psychiatric inpatients who answered the Patient Satisfaction with Mental Health Services Scale (SATIS-BR) and the Perception of Change Scale (EMP). SATIS scores were analyzed according to associations with clinical and sociodemographic data. Pearson correlations were used to correlate SATIS scores with other variables. RESULTS: We found a high degree of satisfaction with care at the psychiatric inpatient unit assessed. In general, patients rated maximum satisfaction for most items. The highest satisfaction scores were associated with patients receiving treatment through the Brazilian Unified Health System (SUS) and with less education. SATIS showed a moderate positive correlation with EMP. The worst evaluated dimension was physical facilities and comfort of the ward. CONCLUSION: Patients treated via SUS may be more satisfied than patients with private health insurance when treated in the same facility. The evaluation of treatment satisfaction can be used to reorganize services at psychiatric inpatient units.

Evaluation of DSM-5 and ICD-11 personality traits using the Personality Inventory for DSM-5 (PID-5) in a Brazilian sample of psychiatric inpatients.

OBJECTIVE: The objective of this study was to test if the Personality Inventory for DSM-5 (PID-5) is an adequate instrument to evaluate psychiatric inpatients' pathological personality traits. METHODS: Inpatients (n = 130; mean age: 38.5 years; 62.3% female; 63.9% single) answered the PID-5 after clinical improvement of their psychiatric symptoms. The mean scores of the DSM-5 personality domains, facets and profiles, and ICD-11 domain traits were compared with the mean scores of a Brazilian normative sample (n = 656). We investigated the diagnostic performance of the scales to identify individuals with and without psychopathology. RESULTS: The final sample included mainly diagnoses of mood disorders. Except for Antagonism and Disinhibition, all DSM-5 personality domains and most facets as well as almost all DSM-5 personality disorder profiles (except Narcissist) and ICD-11 trait domains (except Detachment and Dissociality) of the inpatients presented high differences compared with the normative sample. In general, the PID-5 scales presented a high negative predictive value and a low positive predictive value to identify individuals with severe psychopathology. DISCUSSION: This study found high scores of pathological personality traits in a sample of Brazilian psychiatric inpatients. The PID-5 may be a promising instrument to measure pathological personality traits among psychiatric inpatients. Methodological and sample size limitations may have influenced the results. © 2018 John Wiley & Sons, Ltd.

Sexual behaviors: study in the youth.

OBJECTIVE: To characterize sexual behaviors in a sample of adolescents and youth. METHODS: An analytical descriptive study using a questionnaire about sexual behaviors, adapted from the World Health Organization. It was distributed to students from a Portuguese city aged 14-24 years, during two months. Two age groups were defined: G1 - students aged 14-19 years; G2 - aged 20-24 years. RESULTS: The sample included 2,369 students, 61% females and 70% in G1. The mean age of first sexual intercourse was 16.4±1.8 years; 93% used some contraceptive method in the first sexual intercourse. Out of those who did not use contraception in the first sexual intercourse, 83% were in G1 (p<0.001). Emergency contraception was used at least once by 54% (63% in G2, p<0.001). Among those who had unprotected sexual intercourses, 9% were under the influence of alcohol, 53.6% were female and 53.4% were in G2 (p<0.001). Homosexual contacts occurred in 21% of cases; in that, 62% in G1 and 84% among females (p<0.001). CONCLUSION: The use of contraceptionin the first sexual intercourse was common in our sample. However, the number of adolescents not using any contraceptive method in subsequent sexual intercourses, and the high percentage of them who consider it unnecessary, are a concern. Unprotected sexual intercourses, as well as unplanned intercourses and under influence of alcohol or drugs, especially in the youngest, urge the need for intervention regarding sexual education.

Antiapoptotic effects of cannabidiol in an experimental model of cognitive decline induced by brain iron overload.

Iron accumulation in the brain has been recognized as a common feature of both normal aging and neurodegenerative diseases. Cognitive dysfunction has been associated to iron excess in brain regions in humans. We have previously described that iron overload leads to severe memory deficits, including spatial, recognition, and emotional memory impairments in adult rats. In the present study we investigated the effects of neonatal iron overload on proteins involved in apoptotic pathways, such as Caspase 8, Caspase 9, Caspase 3, Cytochrome c, APAF1, and PARP in the hippocampus of adult rats, in an attempt to establish a causative role of iron excess on cell death in the nervous system, leading to memory dysfunction. Cannabidiol (CBD), the main non-psychotropic component of Cannabis sativa, was examined as a potential drug to reverse iron-induced effects on the parameters analyzed. Male rats received vehicle or iron carbonyl (30 mg/kg) from the 12th to the 14th postnatal days and were treated with vehicle or CBD (10 mg/kg) for 14 days in adulthood. Iron increased Caspase 9, Cytochrome c, APAF1, Caspase 3 and cleaved PARP, without affecting cleaved Caspase 8 levels. CBD reversed iron-induced effects, recovering apoptotic proteins Caspase 9, APAF1, Caspase 3 and cleaved PARP to the levels found in controls. These results suggest that iron can trigger cell death pathways by inducing intrinsic apoptotic proteins. The reversal of iron-induced effects by CBD indicates that it has neuroprotective potential through its anti-apoptotic action.

Iron chelator deferiprone rescues memory deficits, hippocampal BDNF levels and antioxidant defenses in an experimental model of memory impairment.

Brain-derived neurotrophic factor (BDNF) plays a key role in neural development and physiology, as well as in pathological states. Post-mortem studies demonstrate that BDNF is reduced in the brains of patients affected by neurodegenerative diseases. Iron accumulation has also been associated to the pathogenesis of neurodegenerative diseases. In rats, iron overload induces persistent memory deficits, increases oxidative stress and apoptotic markers, and decreases the expression of the synaptic marker, synaptophysin. Deferiprone (DFP) is an oral iron chelator used for the treatment of systemic iron overload disorders, and has recently been tested for Parkinson's disease. Here, we investigated the effects of iron overload on BDNF levels and on mRNA expression of genes encoding TrkB, p75NTR, catalase (CAT) and NQO1. We also aimed at investigating the effects of DFP on iron-induced impairments. Rats received iron or vehicle at postnatal days 12-14 and when adults, received chronic DFP or water (vehicle). Recognition memory was tested 19 days after the beginning of chelation therapy. BDNF measurements and expression analyses in the hippocampus were performed 24 h after the last day of DFP treatment. DFP restored memory and increased hippocampal BDNF levels, ameliorating iron-induced effects. Iron overload in the neonatal period reduced, while treatment with DFP was able to rescue, the expression of antioxidant enzymes CAT and NQO1.
