Fathers of children with autism spectrum disorder: Their perceptions of paternal role a predictor of caregiving satisfaction,self-efficacy and burden

BackgroundThe positive effect of a father’s involvement in children’s upbringing is now recognised. However, research on fathers raising children with autism spectrum disorder (ASD) are still few. This study examines the relationship between the perception, fathers of children with ASD have of the importance of their role in the development of their children and the feelings (self-efficacy, caregiving burden, satisfaction) they express about their parenting experience.MethodSixty-three Swiss Italian fathers of children with ASD completed The Role of the Father Questionnaire (ROFQ), three sub-scales of the Caregiver Survey, a subtest of the Child Adjustment and Parent Efficacy Scale and a home-made questionnaire measuring Perceived Social Support.ResultsThe results from hierarchical multiple regression analyses show that the importance that fathers attach to the paternal role predicts positively their caregiving satisfaction and their feeling of self-efficacy. The children’s challenging behaviours predict positively the caregiving burden whereas the assessment of social support predicts it negatively.ConclusionsThe perception of the importance of the paternal role needs to be considered in the support offered to families with a child with ASD. A better understanding of the fathers’ feelings could be of value for the programmes.     

Intravenous Thrombolysis Is Safe and Effective for the Cryptogenic Stroke in China: Data From the Thrombolysis Implementation and Monitor of Acute Ischemic Stroke in China (TIMS-China)

Background

The intravenous thrombolysis (IVT) with recombinant tissue plasminogen activator (rt-PA) therapy is safe and efficient during the treatment of acute ischemic stroke. Nonetheless, the different outcomes among various stroke subgroups have limited data with regard to the safety and efficacy of cryptogenic stroke (CS). The present study compared the safety and efficacy when IVT with rt-PA was used for the treatment of CS and the other stroke subtypes.

Everyday footwear: An overview of what we know and what we should know on ill-fitting footwear and associated pain and pathology

Footwear has been used to protect feet for millennia with socially exclusive population adopting stylish and fashionable shoes with expensive materials. In terms of historic timeline, only more recently footwear has been worn by all classes in the western world as an integral part of their apparel. Traditionally, footwear has been constructed from natural materials, mainly leather, but has recently benefitted from the flexibility that technology has provided with a plethora materials and new design innovations. Although it has expanded the availability for a variety of consumers, the choice and fit continue to be problematic with many individuals wearing shoes that are ill-fitting. Provision of specific footwear advice for problem feet is poorly evidenced and is heavily practitioner dependant limiting its efficacy. There is limited understanding as to the changes that can occur from regularly wearing footwear that is unsuitable in shape, style and construction which is referred to as ill-fitting. Current research on the effect that everyday footwear has on foot function and pain focuses mainly on women’s shoes, particularly high heels. Defining what is a good fitting shoe, that does not damage the foot or mechanics of walking, may need to be individualised, but best fit is based on loose historical parameters rather than research evidence. The aim of this overview is to highlight aspects of current research, establishing what is known about the effect’s shoes have on the feet as well as exploring the mythology around footwear fit and advice that is often historical in nature.     

Association of genetic variants at MYP10 and MYP15 with high myopia in a Han Chinese population

Background: Previous genome-wide association study (GWAS) has revealed the association between MYP10 at 8p23 and MYP15 at 10q21.1 and high myopia (HM) in a French population. This study is managed to discover the connection between some single nucleotide polymorphism (located at MYP10 and MYP15) and Han Chinese HM.

Methods and Results: This case-control association study contained 1673 samples, including 869 ophthalmic patients and 804 controls. Twelve tag SNPs have been selected from the MYP10 and MYP15 loci and genotyped by SNaPshot method. Among 12 SNPs, rs4840437 and rs6989782 in TNKS gene were found significant association with HM. Carriers of rs4840437G allele and rs4840437GG genotype created a low risk of high myopia (P = .036, OR = 0.81, 95%CI = 0.71–0.93; P = .016, OR = 0.73, 95%CI = 0.56–0.96; respectively). Carriers of rs6989782T allele and rs6989782TT+CT genotype also had a decreased risk of high myopia (P = .048, OR = 0.82, 95%CI = 0.71–0.94; P = .006, OR = 0.74, 95%CI = 0.59–0.92; respectively). Other 10 SNPs displaced nonsignificant association with HM. Additionally, the risk haplotype AC and the protective haplotype GT, generated by two SNPs in TNKS, were considerably more likely to be association with HM (for AC, P = .002 and OR = 1.26; for GT, P = .027 and OR = 0.84).

Conclusions: Our results demonstrated that some heritable variants in the TNKS gene are associated with HM in the Han population. The possible functions of TNKS in the development and pathogenesis of hereditary high myopia still require further researches to identify.     

Investigation of non-linear Mate1-mediated efflux of trimethoprim in the mouse kidney as the mechanism underlying drug-drug interactions between trimethoprim and organic cations in the kidney

The purpose of this study was to elucidate the involvement of Mate1 in the tubular secretion of trimethoprim and saturation of Mate1-mediated efflux to address the mechanisms underlying the pharmacokinetic drug interactions with trimethoprim. Trimethoprim is a more potent inhibitor of MATE2-K than MATE1 with K_i values (μM) of 0.030–0.28 and 2.4–5.9, respectively. Trimethoprim is a substrate of human MATE1 and MATE2-K with K_m values of 2.3 ± 0.9 and 0.018 ± 0.004 μM, and mouse Mate1, but not human OCT2, mouse Oct1 and Oct2. Pyrimethamine significantly reduced the renal clearance (CL_R) of trimethoprim (mL/min/kg) from 40.0 ± 5.1 to 20.1 ± 3.7 (p < 0.05). Trimethoprim was given to mice at three infusion rates (150, 500, and 1500 nmol/min/kg). Together with an increase in the plasma concentrations of trimethoprim, the CL_R (mL/min/kg) of trimethoprim decreased to 25.9 ± 3.2, 13.5 ± 5.7, and 8.92 ± 1.50 at the respective rates. Trimethoprim decreased the CL_R of rhodamine 123 in an infusion rate-dependent manner: 11.5 ± 1.3 (control), 5.17 ± 1.55, 1.31 ± 0.50, and 0.532 ± 0.180. These results suggest that Mate1 mediates the tubular secretion of trimethoprim, and at therapeutic doses, MATEs-mediated efflux can be saturated, and thereby, cause drug interactions with other MATE substrates.     

Pharmacokinetics and brain penetration study of chlorogenic acid in rats

1. The present study is designed to investigate the brain distribution and plasma pharmacokinetics profiles of chlorogenic acid (CGA) after intranasal administration in Charles–Foster rats to evaluate whether the CGA molecules are transported directly via the nose-to-brain path.

2. The CGA is administered intravenously (IV) and intranasally (IN) at the dose of 10?mg/kg. Further, its concentration in the plasma, cerebrospinal fluid (CSF) and the whole brain is analyzed by HPLC-UV method.

3. The study observes that CGA is rapidly absorbed in plasma with t_max of 1?min similar to IV route after IN administration. The peak plasma concentration and AUC_0–24 are higher by 3.5 and 4.0 times respectively in IV administration, compared to IN delivery that represents the significant less systemic exposure of CGA in IN route.

4. However, the concentration of CGA in the brain is 4, 6.5, 5.3, 5.2 and 4.5 times higher at 30, 60, 120, 240 and 360?min, respectively in IN administration compared to IV administration. The exposure of CGA in the brain after IN administration (AUC_{brain, IN}) was significantly greater (4 times) as compared to the exposure of CGA in the brain (AUC_{brain, IV}) after IV administration reflecting significant brain uptake of CGA through nasal route. Therefore, IN delivery of CGA can be a promising approach for the treatment of stroke and neurodegenerative disorders.     

Effect of group reminiscence therapy on depression and perceived meaning of life of veterans diagnosed with dementia at veteran homes

ABSTRACT

Most senior veterans who live in veteran homes in Taiwan have few interpersonal relationships. Aging is often accompanied by solitude and illness, which causes senior veterans to doubt the meaning of life and to lose confidence in the value of life. This study tested the effectiveness of a group reminiscence therapy protocol on the depression and meaning of life among elderly institutionalized veterans. A quasi-experimental design was applied. A convenience sample of older adults was drawn from two veteran homes in southern Taiwan. Participants were assigned to intervention or control groups based on the veterans' homes they attended. The participants in the intervention group carried out group reminiscence therapy for 8 weeks in addition to their daily activities. The participants in the comparison group maintained their daily activities. Both groups were evaluated using the GDS-SF and MLS scale including two aspects of depression mood and meaning of life in weeks 1 and 8. The overall life satisfaction increased significantly over time for the intervention group compared to the comparison group from week 1 to week 8. The group reminiscence therapy programs showed promising effects in improving the depression and meaning of life of older veterans living in veteran homes.
