Summary: The study aimed to identify specific tear biomarkers for dry eye disease (DED) through tear proteomic analysis and clinical parameters. The results showed improvements in tear break-up time, corneal erosion, conjunctival erosion, and symptom assessment scores after treatment. However, no significant differences were found among the different drug groups, except for corneal erosion score. Useful tear protein biomarkers, clinically acceptable biomarker combinations, and adequate levels of specificity and sensitivity were not identified.

Summary: With changing lifestyles and increasing use of digital screens, dry eye disease has become more common. Despite various diagnostic and treatment options, patient satisfaction remains varied. Understanding the molecular basis of the disease may help customize treatment. We propose a stepwise protocol to incorporate biomarker assays in dry eye management.

Summary: This study compares different methods of extracting tear proteins from the Schirmer's strip and finds that the highest protein yield is obtained by incubating the strip in 100 mM ammonium bicarbonate (ABC) with 0.25% Nonidet P-40 (NP-40) at 4 degrees Celsius for an hour. Mass spectrometry analysis reveals unique protein signatures in tear samples from Stevens-Johnson syndrome (SJS) and dry eye disease (DED) patients. This study will contribute to the better design of tear protein-based experimental studies.

Summary: This study compared tear film viscosity in Sjogren and non-Sjogren dry eye diseases. They found that Sjogren patients had lower tear film viscosity indices and higher symptom severity. The researchers concluded that tear film viscosity indices can be useful in early detection of Sjogren dry eye disease.

Summary: Dry eye disease is a chronic ophthalmological disease for which current therapy focuses on symptom suppression. Polyphenols have shown potential in improving dry eye disease therapy. This study aimed to target pathophysiological mechanisms by adding fisetin to the cyclosporine treatment protocol, but it was found that fisetin did not restore tear production but influenced molecular pathological events through MMP-9.

Summary: This study aims to measure the tear flow changes evoked by controlled sensory stimulation of the eye surface using i-Onion (TM), a new stimulation device, in healthy subjects and dry eye disease (DED) patients. The results showed that CO2 stimulation significantly increased tear volume in 78% of control subjects, while DED patients had lower basal tear volume (BTV) and stimulated tear volume (STV) compared to healthy controls.

Summary: The endocrine system plays a role in influencing all tissues and cells in the human body, including the ocular surface. Dry eye disease is a multifactorial disorder, and endocrine anomalies are one of the contributing factors. This review examines the impact of various hormones, such as androgens, estrogens, progesterone, insulin, and thyroid hormones, on the ocular surface and the implications for dry eye disease. The potential use of hormonal therapies in the management of dry eye disease is also discussed.

Summary: Dry eye disease is a multifactorial disorder characterized by tear fluid imbalance. In Asia, the focus of treatment is on tear film stabilization. Traditional therapies like artificial tears and steroids have limitations, while new generation therapies have shown to be more effective in Asia.

Summary: This study investigates the validity and reliability of the German Multidimensional Fatigue Inventory in spinal muscular atrophy and evaluates the presence of clinically relevant fatigue. The results show that the questionnaire has good internal consistency and convergent validity, and can effectively assess different dimensions of fatigue. Fatigue is a significant problem in spinal muscular atrophy and should be incorporated into standard care.

Summary: This study investigated the molecular landscape of Parkinson's disease (PD) in human post-mortem midbrains and identified multiple molecular targets and networks that are relevant to the disease mechanism. The findings suggest that neuroinflammation, immune response activation, mitochondrial dysfunction, and defects in synaptic function could be potential therapeutic targets for advanced PD.

Summary: Parkinson's disease (PD) is a common neurodegenerative disease with a rising prevalence. Infection with SARS-CoV-2 can lead to a complicated disease course for PD patients. Currently, there is a lack of guidelines for managing outpatient PD patients during times of increased infection risk. However, measures such as mask-wearing, hand hygiene, social distancing, and appropriate testing strategies can minimize exposure risk. Telemedicine consultations can be used for low urgency visits, while in-person presentation is required for moderate and high urgency visits. Vaccination against SARS-CoV-2 is safe and effective for PD patients, playing a key role in reducing infection risk.

Summary: Several studies have explored the differences in serum levels of alpha-synuclein autoantibodies (alpha-syn AAb) in Parkinson's disease (PD) patients and healthy subjects, but the results have been inconclusive. In this study, with the largest sample size examined so far, the researchers aimed to validate the use of serum alpha-syn AAb levels as a biomarker for PD and investigate the presence of other synuclein antibodies. The results showed that while the levels of alpha- and beta-syn AAb were significantly reduced in PD patients and other neurodegenerative disorder patients compared to controls, there was high variability in the AAb levels. Furthermore, the alpha-syn AAb levels did not correlate with clinical parameters such as age, disease duration, disease severity, and gender. In conclusion, serum synuclein AAb levels may distinguish PD from healthy subjects but not from other neurodegenerative disorders, indicating that they cannot be regarded as a reliable biomarker for PD.

Summary: This study investigated the prevalence of SARS-CoV-2 infection in hospital staff in Munich, Germany and found that staff engaged in direct patient care had a similar probability of being seropositive as non-patient-facing staff. Increased risk of infection was observed in staff who had interactions with infected coworkers or private contacts, as well as those who had exposure to COVID-19 patients without appropriate personal protective equipment. The study also identified that the infection hotspots for SARS-CoV-2-positive staff and patients only partially overlapped.

Summary: Using the novel data-driven method DEBM, this study determined the sequence of several common biomarker changes in Parkinson's disease (PD). The left putamen was found to be the earliest biomarker to become abnormal, followed by the right putamen, CSF alpha-synuclein, right caudate, left caudate, and serum NfL. The estimated disease stages showed significant differences between PD and healthy controls, and achieved a high accuracy for distinguishing PD from HC.

Summary: This study aimed to investigate the incidence and risk factors for institutionalisation in Parkinson's disease (PD) and atypical parkinsonism (AP). The study found that institutionalisation was more frequent in AP compared to PD and controls. Age, poorer cognition, and more-severe parkinsonian impairment were independent predictors of institutionalisation.
