Summary: While advancing age is the primary risk factor for Alzheimer's disease, approximately one third of dementia cases can be attributed to modifiable risk factors. Recent research has found a link between oral health, the oral microbiome, and the risk and pathophysiology of Alzheimer's disease. The oral microbiome plays a role in the cerebrovascular and neurodegenerative pathology of Alzheimer's disease through inflammatory, vascular, neurotoxic, and oxidative stress pathways. The oral microbiome may have interactions with certain lifestyle risk factors of dementia. Future clinical studies may identify specific oral microbial targets and optimal oral health practices to reduce the risk of dementia.

Summary: There were significant differences in both the structural composition and reaction of the oral microbiota to periodontal treatment between periodontitis patients with and without T2DM. Nonsurgical periodontal treatment can improve metabolic control, decrease the proportion of periodontal pathogens in oral conditions, and help stabilize microbial communities in patients with periodontitis and T2DM. Furthermore, nonsurgical periodontal treatment may be a potential supplementary approach for managing T2DM.

Summary: The success rates of dental implants at 5 and 10 years are nearly 90%. The prevalence of peri-implant diseases, such as peri-implantitis and peri-implant mucositis, is significant. Recent studies using new generation sequencing methods have compared the microbiota of healthy and diseased periodontal and peri-implant sites, revealing distinct differences in diversity and composition. Understanding the characteristics of the peri-implant microbiota can optimize therapeutic strategies for peri-implant diseases.

Summary: Nonsurgical periodontal therapy can result in iatrogenic complications, including operator-dependent harms and errors, as well as adverse effects following the procedures. Soft and hard tissues can be damaged during the treatment, and there is a low risk of bleeding that can be easily controlled. Cervicofacial subcutaneous emphysema is a rare extraoral intraoperative complication, and side effects like pain and dentine hypersensitivity are frequently reported.

Summary: The oral microbiota during pregnancy remains relatively stable but differs significantly from postpartum/non-pregnant status. Pregnancy influences the composition and abundance of oral microorganisms, which are also affected by oral and systemic conditions. Prenatal dental care can reduce the carriage of oral pathogens, while Porphyromonas gingivalis in subgingival plaque is more abundant in women with preterm birth. More future studies are necessary to clarify the association between pregnancy oral microbiota and maternal oral/systemic health as well as birth outcomes due to inconclusive results from meta-analyses.

Summary: There is an urgent need to understand the coupled relationship between belowground microbes and aboveground plants in response to temperature under climate change. The metabolic theory of ecology (MTE) provides a way to predict the metabolic rate and species diversity, but the spatial scale dependence and connections between plants and microorganisms are still unclear. This study used two independent datasets to address this question, and found that the spatial turnover of bacterial communities and microbial functional genes increased with temperature and fitted MTE. Through meta-analysis, this temperature-dependent spatial pattern was further extended to the global scale, indicating a close linkage between belowground microorganisms and aboveground plants.

Summary: The widespread use of the antimicrobial substance triclocarban (TCC) has raised concerns about its impacts on wastewater treatment systems, the environment, and human health. This study investigated the adsorption of TCC by sludge and extracellular polymeric substances (EPS) in a multistage biological process. The results showed that EPS had a higher adsorption capacity for TCC than sludge, potentially due to its loose multilayer structure and abundant functional groups. TCC also had adverse effects on the biological removal of ammonia nitrogen. Our study provides molecular-level insights into the interaction between TCC and activated sludge, and evaluates the risks associated with its presence in wastewater treatment systems through computational modeling.

Summary: Global climate models predict an increase in frequency and intensity of precipitation events worldwide. However, the biosphere-climate feedback to elevated precipitation (eP) is not well understood. This study reports on a long-term experiment assessing the effects of eP, alone or in combination with other climate change drivers, on plants and soil. It was found that eP induced soil C loss and decreased plant root production, possibly due to changes in microbial community composition. The study highlights the importance of the biosphere-climate feedback in water-limited ecosystems.

Summary: Microeukaryotes and bacteria play important roles in aquaculture ecosystems. This study examined their co-occurrence relationships using high-throughput sequencing data. The networks showed dominant phyla of Chlorophyta and fungi in water and sediment, respectively. Most microeukaryotes and bacteria were classified as generalists and had symmetric connections. Some microeukaryotes had asymmetric connections in water. Four microeukaryotes and twelve uncultured bacteria were identified as potential keystone taxa. The microeukaryotic-bacterial bipartite network in sediment had more nestedness compared to water. Loss of microeukaryotes and generalists could lead to the collapse of positive co-occurrence relationships in both water and sediment. This study provides insights into the structure and function of microeukaryotic-bacterial networks in aquaculture ecosystems.
