Background: In tandem with the rise in numbers of older adults in the general population, more people with schizophrenia (PwS) are also living longer. This vulnerable population has several trajectories of ageing driven by a number of social determinants of health, including the experience of loneliness and they may be more at risk of experiencing loneliness.
Aim: This study aimed to examine demographic, psychosocial and clinical variables and their relative contribution to the loneliness of older PwS (OPwS) in a large New Zealand community sample.
Despite diagnostic and therapeutic advances, infective endocarditis (IE) is still associated with high mortality rates. Currently, there are no good prognostic tools for the risk assessment of patients with IE. The CHADS-VASc score, used to estimate the risk of ischemic stroke in patients with non-valvular atrial fibrillation (AF), has been shown to be a powerful predictor of stroke and death in patients without known AF associated with other cardiovascular conditions.

The measured contact angles rely on visible means and are different from their nanoscopic thermodynamic values. This compromises the surface-energy predictions so much that the surface energy-values can be hundreds of percentages higher than expected based on comparisons with different methods as reported in several studies.

Despite some morphological variability posing challenges to training artificial intelligence (AI)-based solutions, these structures are favored potential targets, enabling the recruitment of promising AI-based technologies. Herein, we present a novel AI solution for identifying skin fungal infections, potentially providing a decision support system for pathologists.

Despite these horrific statistics, EA remains largely undetected and under-reported. Available screening methods and tools fail to accurately identify the phenomenon's true prevalence.

Patients with neovascular age-related macular degeneration. With subfoveal, juxtafoveal, or extrafoveal choroidal neovascularization were aged 50 years or older.

Accordingly, an ever-increasing body of research is focusing on understanding the effects of current and future space expeditions on human physiology in health and disease. Yet the complex experimental environment, the small number of participants, and the high cost of space missions are among the primary factors that hinder a better understanding of the impact of space missions on human physiology.

Background: The concept of recovery for people with schizophrenia (PwS) is still a matter of debate. Growing numbers of PwS living to older age calls for examination of their disease trajectories with a focus on recovery.
Aim: To compare two groups of PwS (good wellbeing; poor wellbeing) on several psychosocial variables associated with social wellbeing to identify interventions that support functional recovery.
The combined effects of the cellular environment on proteins led to the definition of a fifth level of protein structural organization termed quinary structure. To explore the implication of potential quinary structure for globular proteins, we studied the dynamics and conformations of Escherichia coli (E. coli) peptidyl-prolyl cis/trans isomerase B (PpiB) in E.

A circuit operating on a single DNA implies that genetically encoded proteins localize during coupled transcription-translation to DNA, but a single-molecule measurement demonstrating this has remained a challenge. Here, we use a genetically encoded fluorescent reporter system with improved temporal resolution and observe the synthesis of individual proteins tethered to a DNA molecule by transient complexes of RNA polymerase, messenger RNA, and ribosome.

There is growing recognition that older persons, both male and female, may experience sexual assault. One clearly identified gap in the body of scientific literature is examination of the criminal justice response for older adults who have been sexually assaulted. This retrospective age-group comparative data analysis examines publicly available population and police statistics for 2018 to describe rates (per 100,000) of reported sexual assault across adult age categories (young adult, = 748; adult, = 1,478; middle age, = 290; older adult, = 58) and compare (using Chi-square bivariate analysis) the criminal justice response to sexual assault for these adult age categories in New Zealand (NZ).

The magnetic ions within the host semiconductor experience spin-exchange interactions with photogenerated carriers and are often involved in the recombination routes, stimulating special magneto-optical effects. The current account presents a comparative study, emphasizing the impact of engineering nanostructures and selecting magnetic ions in shaping carrier-magnetic ion interactions.

Past studies have shown that GroEL undergoes large allosteric conformational changes during its reaction cycle. Here, we report single-molecule Förster resonance energy transfer measurements that directly probe the conformational transitions of one subunit within GroEL and its single-ring variant under equilibrium conditions.

Objective: The primary objective was to survey the Psychiatry of Old Age (POA) service resources in New Zealand: number of psychiatrists, inpatient beds, and community psychogeriatric beds. A secondary objective was to compare the POA service resources reported by frontline clinicians with official government data.
Methods: The New Zealand Branch of Faculty of POA collected information from a POA representative in each of the 20 districts, along with official government data.
Objectives: Clozapine, an atypical antipsychotic used to treat people with schizophrenia, has been proposed as a possible treatment for salivary gland hypofunction. This scoping review investigated the available literature on clozapine's impact on salivary flow, in order to determine whether it could be used by dental practitioners in low doses as a treatment for dry mouth.
Data Sources: An electronic search was completed using Ovid MEDLINE (1996 to Nov 2021).
Objectives: The number of older adults suffering from schizophrenia is increasing. Despite this, less than 1% of published studies about schizophrenia focus on those older than 65 years. Research indicates these individuals may age differently from the general population due to lifestyle, medication factors, and effects of the disease itself.

Yet it remains unknown how often the placenta is at the root of congenital heart defects (CHDs), and what the cellular mechanisms are that underpin this connection. Here, we selected three mouse mutant lines, Atp11a, Smg9 and Ssr2, that presented with placental and heart defects in a recent phenotyping screen, resulting in embryonic lethality.

Background: Modifiable risk factors affect 40% of dementia risk thus creating an opportunity for prevention or delay. The risk factor life-course model of dementia prevention by the Lancet Commission has yet to be tested in the general populations. We aimed to assess the model's assumptions in a large national dataset of older adults assessed for support services.

Copper-doped II-VI and copper-based I-III-VI colloidal quantum dots (CQDs) have been at the forefront of interest in nanocrystals over the past decade, attributable to their optically activated copper states. However, the related recombination mechanisms are still unclear. The current work elaborates on recombination processes in such materials by following the spin properties of copper-doped CdSe/CdS (Cu@CdSe/CdS) and of CuInS and CuInS/(CdS, ZnS) core/shell CQDs using continuous-wave and time-resolved optically detected magnetic resonance (ODMR) spectroscopy.
