Summary: Current research on Parkinson's disease is focusing on identifying objective markers for assessing therapy effects and disease progression. This study found that step length has a significant impact on PD progression, while step time shows minimal change, emphasizing the importance of evaluating quantitative gait parameters for making assumptions about disease progression in chronic progressive diseases like PD.

Summary: This study inferred the progression of Parkinson's disease through MRI observations and found that white matter disintegrity tends to occur earlier than cortical thinning. The staging of structural alterations indicates that these alterations mostly happen before major disease complications, and subsequent alterations are related to more severe clinical symptoms.

Summary: This study examined sex associations to PD phenotypes cross-sectionally and longitudinally in large-scale data. Female PD patients were found to have a higher risk of developing dyskinesia early during the follow-up period, with slower progression in daily living difficulties, and a lower risk of developing cognitive impairments compared with male patients. The findings were consistent in both longitudinal, clinic-based cohorts and an online-only cohort.

Summary: In many communities, speech to infants and small children has distinct features compared to speech to adults, which can also be observed in speech directed to foreigners. This study examines the vowel acoustics in the Nungon language of Papua New Guinea, specifically in child-directed speech, conversational speech, and monologues directed towards a non-native speaker. The findings show that Nungon child-directed speech lacks vowel hyper-articulation but displays other prosodic traits common to child-directed speech. Furthermore, the vowel patterns in Nungon foreigner-directed speech are significantly different from those in child-directed speech and conversational speech. This study contributes to the understanding of speech variation and its cultural implications in different linguistic communities.

Summary: Longitudinal PD CSF samples were analyzed using ICP-MS to quantify the total amount of iron and other bioelements. In addition, ferritin and protein biomarkers of neurodegeneration were measured. Over time, mean iron levels significantly increased while ferritin levels decreased.

Summary: Objective: GBA variants and onset age significantly affect clinical phenotype and progression in Parkinson's disease (PD). This study compared clinical characteristics and cognitive and motor progression among GBA-PD, early-iPD, and late-iPD patients. Results showed that GBA-PD patients had more severe symptoms and faster progression compared to early-iPD and late-iPD patients. However, onset age did not have a significant impact on clinical features and progression in GBA-PD patients.

Summary: Asymmetric hemispheric loss of dopaminergic neurons in Parkinson's disease affects cognitive and motor performance differently, with greater motor severity associated with predominant right hemisphere nigrostriatal dopaminergic loss and more pronounced left hemisphere denervation affecting cognitive manifestations at onset and progression.

Summary: This study summarizes the literature on speech and voice in detecting and assessing the severity of Parkinson's disease (PD). Speech and voice may be valuable markers for PD, but there are differences between datasets and limitations in analysis methods.

Summary: This study investigated gait impairment in the early and progressive stages of Parkinson's disease using a wearable sensor-based gait analysis system. The results showed significant differences in gait parameters such as stride length, gait velocity, and joint range of motion between Parkinson's disease patients and healthy controls at different stages. These gait parameters were also found to be correlated with Parkinson's disease rating scales and questionnaires.

Summary: Phosphorus is a crucial nutrient for cell and tissue function, but excess intake can lead to adverse medical consequences, particularly in chronic kidney disease and diabetic kidney disease patients. High levels of phosphorus may impact cardiovascular health and exacerbate mineral and bone disorders.

Summary: Periodontal disease is a chronic oral inflammatory disorder caused by pathobiontic bacteria in dental plaques, which, if untreated, can lead to periodontitis and tooth loss. Current diagnosis relies on obvious tissue damage, highlighting the need for improvements in diagnostic methods. Recent research indicates that specific lipids derived from periodontal pathogens could serve as biomarkers for periodontal disease and other chronic inflammatory conditions.

Summary: This study conducted a meta-analysis on PD-MCI patients and found significant differences in cognitive test performance, with cognitive screeners showing the most pronounced effect. In the progression from PD-MCI to PDD, executive dysfunction exhibits a significant impact.

Summary: This study evaluated the trend of Immature Platelet Fraction (IPF) as an early recovery indicator of platelets in dengue patients with thrombocytopenia, and its relationship with severe dengue in conjunction with reticulocyte count. The results showed that IPF% increased significantly in severe dengue patients on days 3-5 after the onset of fever, and reticulocyte count also increased significantly on day 5. IPF can be utilized as an early recovery indicator of platelets in patients with dengue and thrombocytopenia.

Summary: This study aims to detect early, subclinical speech biomarkers of dysarthria in Parkinson's disease (PD), which are systematic atypicalities in speech that are not easily detectible by clinicians. The study found that vowel articulation, assessed by three acoustic metrics, can be used as an early indicator of speech difficulties associated with PD.
