Concomitant Potentially Contagious Factors Detected in Poland and Regarding Strains, Etiological Agents of Keratitis in Humans.

Background: Diseases in humans caused by amphizoic amoebae that can result in visual impairment and even blindness, have recently been identified more frequently worldwide. Etiologically complex incidents of keratitis, including those connected with strains detected in Poland, were evaluated in this study.

Methods: Corneal samples from cases resistant to antimicrobial therapy assessed for epidemiological, microbiological and parasitological aspects were investigated by phase-contrast microscope, slit lamp and by confocal microscopy.

Canadian Clinical Guidelines on Social Isolation and Loneliness in Older Adults.

Background: Preventing and addressing social isolation and loneliness among older adults is important because of the known associations with negative health outcomes. The Canadian Coalition for Seniors' Mental Health (CCSMH) took on the task of creating clinical guidelines.

Method: A multidisciplinary working group was established.

Embracing Connection: A Review of First-Ever Clinical Guidelines on Social Isolation and Loneliness in Older Adults.

Social isolation and loneliness are major public health concerns and are associated with morbidity and mortality. As this is an increasing issue in older adults, guidance for healthcare providers is a priority. The Canadian Coalition for Senior's Mental Health (CCSMH) has developed the first Canadian social isolation and loneliness guidelines to help providers recognize, assess, and manage social isolation and loneliness among older adults.

Can 'What Is Known' about Social Isolation and Loneliness Interventions Sufficiently Inform the Clinical Practice of Health Care and Social Service Professionals Who Work with Older Adults? Exploring Knowledge-to-Practice Gaps.

Establishing intervention effectiveness is an important component of a broader knowledge translation (KT) process. However, mobilizing the implementation of these interventions into practice is perhaps the most important aspect of the KT cycle. The purpose of the current study was to conduct an umbrella review to (a) identify promising interventions for SI&L in older adults, (b) interpret (translate) the findings to inform clinical knowledge and practice interventions in different settings and contexts, and (c) highlight research gaps that may hinder the uptake of these interventions in practice.

Evaluating the impact of a national geriatric mental health ECHO educational program on healthcare providers' practice.

Project Extension for Community Healthcare Outcomes (ECHO) enables healthcare providers to share knowledge and best practices via telementoring. The ECHO model builds provider capacity and improves care for patients with a variety of health conditions. This study describes a Canada-wide National ECHO pilot project in the area of geriatric mental health and reports on the program's impact on providers' care practices.

Timely Yet Long Overdue: Canadian Standards for Long-Term Care Homes.

The impact of the COVID-19 pandemic highlighted systemic problems in Canadian long-term care (LTC). While high mortality rates in LTC received significant attention, the pandemic also took an enormous toll on mental health of LTC residents, where mental health conditions, including cognitive disorders, are already much higher than in other community settings. The pandemic resulted in a renewed interest in improving quality of care in LTC and led to the recent development of several National Standards of Canada.

Tannic Acid-Modified Silver Nanoparticles in Conjunction with Contact Lens Solutions Are Useful for Progress against the Adhesion of spp. to Contact Lenses.

spp. are amphizoic amoebae that are widely distributed in the environment and capable of entering the human body. They can cause pathogenic effects in different tissues and organs, including keratitis (AK), which may result in a loss of visual acuity and blindness.

ULTRASTRUCTURE AND CYTOCHEMISTRY OF LATE EMBRYOS AND COTYLOCIDIUM LARVAE OF ROHDELLA AMAZONICA (TREMATODA: ASPIDOGASTREA), FROM THE TROPICAL ESTUARINE FISH, COLOMESUS PSITTACUS.

Developmental ultrastructure of late embryos and cotylocidium larval morphogenesis of Rohdella amazonica, an aspidogastrean parasite of fish, were studied to reveal the functional aspects of larvigenesis within the egg as well as phylogenetically relevant characteristics of the embryos and larvae in this basal trematode group. Gravid worms were removed from the intestine of naturally infected banded puffer fish Colomesus psittacus, collected from the Bay of Marajó, Paracauari River (Pará, Brazil) and processed by standard methods of transmission electron microscopy (TEM) and cytochemistry. During late cleavage and rearrangement of the blastomeres, the vitelline syncytium that plays a role in eggshell formation and nutrient provision to the embryo completes its apoptotic degeneration as the embryonic mass grows substantially.

ULTRASTRUCTURE OF EGG ENVELOPES AND EARLY EMBRYOS OF ROHDELLA AMAZONICA (TREMATODA: ASPIDOGASTREA) PARASITIC IN BANDED PUFFER FISH, COLOMESUS PSITTACUS.

Egg structure and early embryonic development of the aspidogastrean, Rohdella amazonica, a basal trematode, were studied by transmission electron microscopy (TEM) to gain insight into functional, developmental, and phylogenetic characteristics. Gravid worms were removed from the intestine of naturally infected banded puffer fish Colomesus psittacus, collected from the Bay of Marajó, Paracauari River (Pará, Brazil) and processed by standard TEM methods. By the time of pronuclear fusion, the fertilized zygote was already enclosed in a thick, electron-dense pre-operculate eggshell and an underlying layer of vitellocytes that fused into a vitelline syncytium as they were still secreting their shell granules.

Position Statement for Mental Health Care in Long-Term Care During COVID-19.

COVID-19 has disproportionately impacted older adults in long-term care (LTC) facilities in Canada. There are opportunities to learn from this crisis and to improve systems of care in order to ensure that older adults in LTC enjoy their right to the highest attainable standard of health. Measures are needed to ensure the mental health of older adults in LTC during COVID-19.

Infection of Mammary Glands of Small Mammals in Eastern North America by Helminths.

To determine whether small mammals living in natural settings harbor helminth infections in their mammary glands, we conducted a survey of helminths infecting rodents and soricimorphs in three widespread locations in the eastern United States: states of New York, Tennessee, and Georgia. We examined all the primary organs in all hosts, and identified all helminths. We also excised the complete mammary glands within their subcutaneous fat pads, then stained and mounted each whole mammary gland set for microscopical examination.

Primary Progressive Aphasia Presenting With Neuropsychiatric Symptoms.

We describe a case of primary progressive aphasia (PPA) with an underlying neurodegenerative motor disorder (possible ALS or PSP), presenting with symptoms of irritability and frustration, that were misdiagnosed and treated as a primary psychiatric disorder, i.e. depression.

ECHO Care of the Elderly: Innovative Learning to Build Capacity in Long-term Care.

Background: Older adults are entering long-term care (LTC) homes with more complex care needs than in previous decades, resulting in demands on point-of-care staff to provide additional and specialty services. This study evaluated whether Project ECHO (Extension for Community Healthcare Outcomes) Care of the Elderly Long-Term Care (COE-LTC)-a case-based online education program-is an effective capacity-building program among interprofessional health-care teams caring for LTC residents.

Methods: A mixed-method, pre-and-post study comprised of satisfaction, knowledge, and self-efficacy surveys and exploration of experience via semi-structured interviews.

Building Long-Term Care Staff Capacity During COVID-19 Through Just-in-Time Learning: Evaluation of a Modified ECHO Model.

Objectives: The onset of the COVID-19 pandemic significantly challenged the capacity of long-term care (LTC) homes in Canada, resulting in new, pressing priorities for leaders and health care providers (HCPs) in the care and safety of LTC residents. This study aimed to determine whether Project ECHO (Extension for Community Healthcare Outcomes) Care of the Elderly Long-Term Care (COE-LTC): COVID-19, a virtual education program, was effective at delivering just-in-time learning and best practices to support LTC teams and residents during the pandemic.

Design: Mixed methods evaluation.

Comparing a clinician-assisted and app-supported behavioral activation intervention to promote brain health and well-being in frontline care.

Background: Positive psychiatry offers an unique approach to promote brain health and well-being in aging populations. Minimal interventions through behavioral activation to promote wellness are increasingly available using self-guided apps, yet little is known about the effectiveness of app technology or the difference between clinician-supported behavioral activation versus self-guided app methodologies.

Objectives: Investigate the difference in users and outcomes between two methods of the Fountain of Health (FoH) positive psychiatry intervention for behavioral activation to promote brain health and well-being: (1) clinician-assisted and (2) independent app use for behavioral self-management.

Canadian Guidelines on Benzodiazepine Receptor Agonist Use Disorder Among Older Adults Title.

Background: Benzodiazepine receptor agonist (BZRA) use disorder among older adults is a relatively common and challenging clinical condition.

Method: The Canadian Coalition for Seniors' Mental Health, with financial support from Health Canada, has produced evidence-based guidelines on the prevention, identification, assessment, and management of this form of substance use disorder.

Results: Inappropriate use of BZRAs should be avoided by considering non-pharmacological approaches to the management of late life insomnia, anxiety, and other common indications for the use of BZRA.

Effects of medical and non-medical cannabis use in older adults: protocol for a scoping review.

Introduction: With its legalisation and regulation in Canada in 2018, the proportion of Canadians reporting cannabis use in 2019 increased substantially over the previous year, with half of new users being aged 45+ years. While use in older adults has been low historically, as those born in the 1950s and 1960s continue to age, this demographic will progressively have more liberal attitudes, prior cannabis exposure and higher use rates. However, older adults experience slower metabolism, increased likelihood of polypharmacy, cognitive decline and chronic physical/mental health problems.

Ultrastructure and cytochemistry of intrauterine embryonic and larval stages of Ityogonimus lorum (Digenea: Brachylaimidae) involving transitory development of ciliated miracidia.

Results of the present study provide ultrastructural evidence that miracidial morphogenesis is fully completed within the intrauterine eggs while in the most posterior uterine regions of Ityogonimus lorum, a digenean parasite of an Iberian mole, Talpa occidentalis (Eulipotyphla, Talpidae). Using transmission electron microscopy (TEM), the ultrastructural characteristics of diverse cell types and their organelles of these developing embryos and fully formed miracidia within the eggshell were examined. The eggshell and embryonic envelopes are similar to those described previously by many authors for other digeneans.

Examination of oral biofilm microbiota in patients using fixed orthodontic appliances in order to prevent risk factors for health complications.

Introduction And Objective: In recent decades the use of orthodontic appliances in Poland has increased; however, data on their influence on changes of components of the microbiome connected with oral biofilm are scarce. The objective of this study was to evaluate oral microbiota in terms of their role as risk factors for health complications.

Material And Methods: The study included 100 patients treated with removable or fixed appliances.

Effect of povidone iodine, chlorhexidine digluconate and toyocamycin on amphizoic amoebic strains, infectious agents of keratitis - a growing threat to human health worldwide.

Introduction: Free-living amoebae, ubiquitous in outer environments, in predisposing circumstances may exist as parasites, infectious agents of Acanthamoeba keratitis. In recent decades, the vision-threatening corneal infection is a growing human health threat worldwide, including Poland. The applied therapy is often ineffective due to diagnostic mistakes, various pathogenicity of Acanthamoeba strains and high resistance of cysts to drugs; many agents with possible anti-amoebic activity are still being tested.
