The aim of this systematic review and meta-analysis was to evaluate the efficacy of indocyanine green-mediated photodynamic therapy (ICG-PDT) as an adjunct to non-surgical periodontal therapy (NSPT), in the management of chronic periodontitis.
Four electronic databases (PubMed, Cochrane Central Register of Controlled Trials, Embase via OVID, Web of Science) were searched for randomised controlled trials comparing NSPT with ICG-PDT to NSPT without laser therapy. Primary outcome measures were changes in probing pocket depth (PPD) and clinical attachment level (CAL). Clinical outcomes were extracted and pooled from 7 eligible trials and meta-analyses conducted using mean difference with standard deviations.
For PPD, adjunctive ICG-PDT resulted in a mean additional reduction of 1.17 mm (95% CI 0.67-1.66 mm) at 3 months and a mean additional reduction of 1.06 mm (95% CI 0.54-1.57 mm) at 6 months. For CAL, adjunctive ICG-PDT resulted in a mean additional gain of 0.70 mm (95% CI 0.17-1.23 mm) at 3 months and a mean additional gain of 1.03 mm (95% CI 0.83-1.24 mm) at 6 months. No adverse events were reported in any studies.
The adjunctive use of ICG-PDT in NSPT results in improved treatment outcomes at 3 and 6 months post-therapy. Further investigation is needed to evaluate variables such as different photosensitiser concentrations and adjusting parameters associated with the light source.
Indocyanine green-based photosensitisers may be a novel, clinically efficacious agent for use in the management of periodontitis.

This study aimed to assess whether the emergency service of a major Swiss dental institution faced different demands (patient volume, treatment needs, dental care characteristics) during a lockdown, issued to mitigate the COVID-19 pandemic, compared with the weeks before and after.
Data of patients receiving urgent care at a university center for dental medicine (Basel, Switzerland) during the 6-week lockdown, pre-lockdown, and post-lockdown periods were retrospectively evaluated. Statistical analysis involved tests for equal proportions and logistic regression models. The level of significance was set at α=0.05.
The study comprised 3109 dental emergency visits in the period from February 2 to June 5, 2020. Daily caseloads increased during lockdown. Abscesses, orthodontic emergencies, and surgical follow-ups were more common during lockdown, whereas the number of dento-alveolar injuries declined (≤0.048). Urgent dental care provision involved intraoral radiographs more frequently in the pre-lockdown period compared with the following weeks (p<0.001). Among all treatments, aerosol-generating procedures dropped from 56.1% (pre-lockdown) to 21.3% during lockdown (p<0.001), while teledentistry follow-ups became more frequent (p<0.001). selleckchem Patients with comorbidities sought urgent dental care less frequently during the post-lockdown period (p=0.004).
The lockdown significantly impacted the dental emergency service in terms of patients' diagnoses, treatment needs, and the characteristics of the urgent care that was delivered.
Access to essential dental care must be monitored and safeguarded throughout the COVID-19 pandemic and beyond as deferred care entails risks for serious sequelae and persons with comorbidities may change their dental care-seeking behavior.

Patients with neurogenic orthostatic hypotension in the setting of Lewy body diseases (LBnOH) typically have baroreflex failure and peripheral noradrenergic deficiency. Either or both of these abnormalities might determine the magnitude of OH in individual patients. We retrospectively correlated the orthostatic fall in systolic blood pressure (∆BPs) during active standing or 5min of head-up tilt at 90° from horizontal as a function of several baroreflex and sympathetic noradrenergic indices.
Physiological, neurochemical, and sympathetic neuroimaging data from the Valsalva maneuver, head-up tilt table testing, and thoracic
F-dopamine positron emission tomographic scanning (
F-DA PET) were analyzed from 72 patients with LBnOH [44 with Parkinson disease (PD) and nOH, 28 with pure autonomic failure]. Comparison subjects had PD without OH (N = 44) or PD risk factors without parkinsonism or OH (N = 28) or were healthy volunteers (N = 8). Indices of baroreflex function included the Valsalva maneuver-associate of OH, even under controlled laboratory conditions.Compost has been widely used in agriculture in recent years, but the nutrients it provides are far from enough for plant growth. Therefore, it is necessary to systematically explore the fermentation process of composting. In this study, the succession of microbial community and metabolite characteristics in compost were analyzed by using microbial sequencing and metabolomics techniques. The results showed that compared with mesophilic phase and cooling phase, the richness and diversity of bacterial community decreased in thermophilic phase. At the genus level, Pseudomonas (8.90%), Lactobacillus (3.99%), Bacteroidetes (3.39%), Flavobacterium (3.25%) and Prevotella (Prevotella_9, 2.33%, Prevotellaceae_NK3B31_group, 2.44%) were the dominant genera in the pig manure composting. The abundance of Pseudomonas and Flavobacterium increased significantly while Lactobacillus and Prevotella were significantly decreased after composting, and the abundance of Bacteroidetes increased first and then decreased. Fatty acyls, sterol lipids, glycerophospholipids, polyketides and prenol lipids were common microbial metabolites in compost. Moreover, the linoleic acid metabolic pathway was significantly enriched in the three stages of composting, and linoleic acid metabolism might be the primary function of the microbial community in composting. The network analysis showed that between the microbial communities or between the microbial community and metabolites were closely related to each other.selleckchem
