Background And Objective: The authors compare low fluence photodynamic therapy (PDT) against graded subthreshold transpupillary thermotherapy (TTT) for chronic central serous chorioretinopathy (CSC).
Patients And Methods: Forty-two eyes of 42 patients with chronic CSC were included in this prospective, nonrandomized, interventional trial. All patients were offered PDT as an initial intervention. If they declined PDT, TTT was offered.
Results: Twenty patients underwent PDT and 22 underwent TTT. The difference in best-corrected visual acuity between the TTT and PDT groups at baseline and at 6 months after treatment was not significant (P = .728). The mean foveal thickness decreased significantly in both groups (P = .001). However, patients in the TTT group required more treatments (P = .013) and longer time for resolution of the CSC (P = .013).
Conclusions: Both PDT and TTT may be equally effective in the treatment of chronic CSC. Graded subthreshold TTT may be a cost-effective and safe alternative for PDT. [Ophthalmic Surg Lasers Imaging Retina. 2017;48:334-338.].

Objective: This study aimed to analyze the effects of physical activity (PA), sleep quality, and sedentary behavior on subthreshold depression (StD) among undergraduates.
Methods: This study included 834 undergraduates and assessed the impact of PA time, sleep quality, and sedentary behavior on depression. The receiver operating characteristic (ROC) analysis was performed to determine cut-off values for StD risk, while the isochronous substitution analysis was performed to evaluate the effects of different activities on depression regulation.

Article Synopsis
- Researchers developed a new genetically encoded voltage indicator (GEVI) called ASAP5, which offers improved detection of excitatory postsynaptic potentials (EPSPs) and action potentials (APs) with better signal quality compared to previous indicators.
- ASAP5 was able to detect both spiking and subthreshold neuronal activities in real-time, showing its effectiveness in both animal models and cultured human neurons, even capturing small EPSPs of about 1-mV.
- The study revealed that EPSP amplitudes decrease as they move away from the source, with further implications for using voltage imaging in studying neuronal dysfunction related to diseases, including those affecting human neurons.
The effect of intermittent theta burst stimulation for cognitive dysfunction: a meta-analysis.

Background: Growing evidence suggests that cognitive dysfunction significantly impacts patients' quality of life. Intermittent theta burst stimulation (iTBS) has emerged as a potential intervention for cognitive dysfunction. However, consensus on the iTBS protocol for cognitive impairment is lacking.

Several in vivo studies have shown that systemic inflammation, mimicked by LPS, triggers an inflammatory response in the CNS, driven by microglia, characterized by an increase in inflammatory cytokines and associated sickness behavior. However, most studies induce relatively high systemic inflammation, not directly compared with the more common low-grade inflammatory events experienced in humans during the life course. Using mice, we investigated the effects of low-grade systemic inflammation during an otherwise healthy early life, and how this may precondition the onset and severity of Alzheimer's disease (AD)-like pathology.

Background: Traumatic brain injury (TBI) adversely affects both young and old and is a growing public health concern. The common functional, psychological, and cognitive changes associated with TBI and recent trends in its management, such as recommending sub-threshold aerobic activity, and multi-modal treatment strategies including vestibular rehabilitation, suggest that Tai Chi/Qigong could be beneficial for TBI. Tai Chi and Qigong are aerobic mind-body practices with known benefits for maintaining health and mitigating chronic disease.
