Introduction—Aim: Agitation and aggression are common symptoms in people with Alzheimer’s disease and other dementias. This systematic review outlines the current evidence for the effect of antidementia treatments on agitation and aggression in patients with Alzheimer’s disease. Methods: The literature search was performed by manually checking articles published since 2000 in the following databases: PubMed, ResearchGate, and Google Scholar, following the PRISMA guidelines. Results: Nineteen double blinded placebo-controlled trials were included. Treatment with galantamine seems to provide more credible evidence for treating or preventing agitation/aggression. Studies on memantine often presented with an improvement of the neuropsychiatric inventory but not specifically on agitation/aggression. The trials on donepezil and rivastigmine either did not include enough information on agitation/aggression or did not provide compelling results. The incidence of agitation as an adverse event was not higher in antidementia treatments compared to placebo. Conclusions: Agitation and aggression are common symptoms of Alzheimer’s disease and have a significant impact on the patient, caregiver, and the broader healthcare system. The current literature lacks robust evidence on which of the antidementia treatments could be used to manage or prevent agitation and aggression in Alzheimer’s disease. In most included studies, no specific scores that assess those symptoms were used. Future research that specifically focuses on different disease phenotypes and behavioral profiles to enhance and facilitate the management of these symptoms is needed. Full article

Childhood glaucoma encompasses a group of rare but severe ocular disorders characterized by increased intraocular pressure (IOP), posing significant risks to vision and quality of life. Primary congenital glaucoma has a prevalence of one in 10,000–68,000 people in Western countries. More worryingly, it is responsible for 5–18% of all childhood blindness cases. According to the Childhood Glaucoma Research Network (CGRN), this spectrum of disease is classified into primary glaucoma (primary congenital glaucoma and juvenile open-angle glaucoma) and secondary glaucomas (associated with non-acquired ocular anomalies, non-acquired systemic disease, acquired conditions, and glaucoma after cataract surgery). They present very specific ocular characteristics, such as buphthalmos or progressive myopic shift, corneal modifications such as Haab striae, corneal edema or increased corneal diameter, and also glaucoma findings including high intraocular pressure, specific visual fields abnormalities, and optic nerve damage such as increased cup-disc ratio, cup-disc ratio asymmetry of at least 0.2 and focal rim thinning. Surgical intervention remains the cornerstone of treatment, and initial surgical options include angle surgeries such as goniotomy and trabeculotomy, aimed at improving aqueous outflow. For refractory cases, trabeculectomy and glaucoma drainage devices (GDDs) serve as second-line therapies. Advanced cases may require cyclodestructive procedures, including transscleral cyclophotocoagulation, reserved for eyes with limited visual potential. All in all, with appropriate management, the prognosis of PCG may be quite favorable: stationary disease has been reported in 90.3% of cases after one year, with a median visual acuity in the better eye of 20/30. Immediate recognition of the specific signs and symptoms by caregivers, primary care providers, and ophthalmologists, followed by prompt diagnosis, comprehensive surgical planning, and involving the caregivers in the follow-up schedule remain critical for optimizing outcomes in childhood glaucoma management.

Tactile maps designed for individuals with blindness can greatly improve their mobility, safety and access to new locations. While 3D-printed maps have already been demonstrated to be a powerful tool for delivering spatial information, they might not always be available. Alternatively, a combination of audio and haptic information can be used to efficiently encode 2D maps. In this paper, we discuss the development and user-testing of a novel audio-haptic map creator application. Maps created using this application can provide people with blindness with a tool for understanding the navigational routes and layouts of spaces before physically visiting the site. Thirteen people with blindness tested various components of the virtual map application, such as audio, haptic feedback and navigation controls. Participants’ data and feedback were collected and analyzed to determine the effectiveness of the virtual maps as it relates to this user group’s readability and usability. The study showed that it was easy to use and that it efficiently delivered information about travel routes and landmarks that the participants could successfully understand. Full article

Cataract is a major cause of blindness worldwide. In particular, in low-income countries, the burden of disease as well as its direct and indirect economic cost are a major challenge for the population and economy. In many cases, it would be possible to prevent or cure blindness with a comparably simple cataract surgery, but many countries lack the resources to strengthen healthcare systems and implement broad cataract surgery programs reaching, in particular, the rural poor. In this paper, we analyse whether such an intervention could be cost-effective or even cost-saving for the respective health systems. We calculate the net value of the lifelong costs of cataract with and without surgery. This calculation includes direct costs (e.g., treatment, glasses, surgery) as well as indirect cost of the caregiver and the patient. We total all costs from the year of onset of cataract until death and discount the respective values to the year of onset. We define the surgery as cost-saving if the net-value of costs with surgery is lower than without surgery. If the cost per quality adjusted life year is lower than one gross national product per capita, we define the intervention as highly cost-effective. We find that the cost-effectiveness of cataract surgery depends on the age of onset of the disease and the age of surgery. If the surgery is performed with the beginning of severe impairment, even surgery of a 78-year-old patient is still cost-saving. Almost all possible constellations are highly cost-effective, only for the very old it is questionable whether the surgery should be performed. The simulations show that cataract surgery is one of the most cost-effective interventions. However, millions of people in low-income countries still have no chance to prevent or cure blindness due to limited resources. The findings of this paper clearly call for a stronger effort to reach poor and rural populations with this cost-effective service. Full article

Female caregivers of people with disabilities are burdened physically and mentally. To improve these symptoms, an intervention that is easy to apply and has fewer side effects, such as natural healing, has been proposed, but the effect of healing using marine resources is unclear until now. The purpose of this study is to investigate the effect of meditation accompanied with stabilization exercise in the marine region on the improvement of pain, tactile sense, muscle characteristics, muscle strength, balance, quality of life, and depression in female caregivers of people with severe physical disabilities. Twenty-four female family caregivers were recruited and were randomly assigned to the marine therapy group (MTG, n = 12) and the control group (CG, n = 12). Both groups performed the same meditation (35 min) and stabilization exercise (25 min) twice a day for 3 nights and 4 days per session (total 8 sessions). The MTG performed these in the marine region, whereas the CG performed the interventions in the urban region. Pain (pain intensity and pain pressure threshold), tactile sense (tactile spatial acuity), muscle characteristics (stiffness, elasticity), muscle strength (hand and pinch grip strength), balance, quality of life, and depression were measured before and after the intervention and 4 weeks after the intervention. Both groups showed significant improvements in pain intensity (resting pain: f(2) = 72.719, p < 0.001; movement pain: f(2) = 24.952, p < 0.001), muscle strength (right pinch grip: f(2) = 15.265, p < 0.001), and depression (f(2) = 13.312, p < 0.001), while tactile spatial acuity (TSA) (upper part: f(2) = 14.460, p < 0.001; lower part: f(2) = 7.672, p = 0.002), dynamic balance (f(2) = 4.196, p = 0.024), and quality of life (overall quality of life & general health: f(2) = 5.443, p = 0.009; physical health: f(2) = 13.991, p < 0.001; psychological: f(2) = 9.946, p < 0.001; environmental: f(2) = 20.004, p < 0.001; total: f(2) = 11.958, p < 0.001) were significantly improved only in MTG. There was no significant change in pain pressure threshold (upper trapezius (UT): f(2) = 0.765, p = 0.473; levator scapula (LS): f(2) = 0.213, p = 0.809; splenius capitis (SC): f(2) = 0.186, p = 0.831) and muscle characteristics (UT stiffness: f(2) = 1.486, p = 0.241; UT elasticity: f(2) = 0.358, p = 0.702; LS stiffness: f(2) = 2.440, p = 0.102; LS elasticity: f(2) = 0.544, p = 0.585) in both groups. In comparison between groups, the MTG showed a significant difference in sensory function compared to the CG (resting pain: f(2) = 10.487, p = 0.005; lower part: f(2) = 5.341, p = 0.034 in TSA). Our findings suggest that meditation combined with stabilization exercise improved pain, muscle strength, and depression of female caregivers. In particular, greater benefits on tactile sense, balance, and quality of life were found in performing these in the marine region compared to the urban region. Full article

There are multiple studies demonstrating that 3D printed maps are important to people with blindness. When designed properly, they help users by improving safety and mobility and allow people with blindness to efficiently learn spatial information from the map and plan their travel prior to navigation. However, tactile maps are still not widely among people with blindness, as they are not readily available to them. Creating maps for each person needing a map of a certain location currently requires help from an individual with advanced technical training. They need to use specialized software for 3D models that personnel from disability services and family members of people with blindness usually have no experience with. The goal of this research is to design and implement software that can be used for the automatic generation of maps and be accessible to the general public. Our hypothesis is that by automating all the challenging steps (generation of the 3D model and drawing of optimally designed symbols), this will lead to increased usability and acceptance. Here, we demonstrated an early prototype and evaluated our hypothesis in a user study. To assess the success of this approach, participants answered questions about the process, usability, and social impacts of the software. Overall, participants liked the application because it was easy to use and allowed them to create custom maps with appropriate tactile-encoding features that provide meaningful information to the end user.

Facilitated self-help and problem-solving strategies can empower and support family carers to cope with caregiving for people with severe mental illnesses. This single-blind multi-site randomised controlled trial examined the effects of a five-month family-facilitated problem-solving based self-learning program (PBSP in addition to usual care), versus a family psychoeducation group program and usual psychiatric care only in recent-onset psychosis, with a six-month follow-up. In each of three study sites (integrated community centres for mental wellness), 114 people with early psychosis (≤5 years illness onset) and their family carers were randomly selected and allocated to one of three study groups (n = 38). Caregiving burden (primary outcome) and patients’ and carers’ health conditions were assessed at recruitment, and one-month and six-months post-intervention. Overall, 106 (94.7%) participants completed the assigned intervention and ≥1 post-test. Generalised estimating equations and subsequent contrast tests indicated that the PBSP participants showed significantly greater improvements in carers’ burden, caregiving experiences and problem-solving ability, and patients’ psychotic symptoms, recovery, and duration of re-hospitalisations over the six-month follow-up, compared with the other two groups (moderate to large effect size, η² = 0.12–0.24). Family-assisted problem-solving based self-learning programs were found to be effective to improve both psychotic patients’ and their carers’ psychosocial health over a medium term, thus reducing patients’ risk of relapse.
