Osteoarthritis (OA) and rheumatoid arthritis (RA) are both debilitating diseases that cause significant morbidity and disability globally. This study aims to investigate the causal effects of varying blood levels of five minerals -- iron, zinc, copper, calcium, and magnesium, on OA and RA.

We performed two-sample Mendelian randomization (MR) analyses to assess the associations of five circulating minerals with OA and RA. Single nucleotide polymorphisms (SNPs) serving as genetic instruments for the circulating mineral levels were selected from large genome-wide association studies of European-descent individuals. The associations of these SNPs with OA and RA were evaluated in UK Biobank participants. Multiple sensitivity analyses were applied to detect and correct for the presence of pleiotropy.

Genetically determined copper and zinc status were associated with OA, but not with RA. Per standard deviation (SD) increment in copper increases the risk of OA (OR=1.07, 95% CI 1.02-1.13) and one of its subtypes, localized OA (OR=1.08, 95% CI 1.03-1.15). Per SD increment in zinc is positively associated with risks of OA (OR=1.07, 95% CI 1.01-1.13), generalized OA (OR=1.18, 95% CI 1.05-1.31), and unspecified OA (OR=1.21, 95% CI 1.11-1.31). Additionally, per SD increment in calcium decreases the risk of localized OA (OR=0.83, 95% CI 0.69-0.98).

Genetically high zinc and copper status were positively associated with OA, but not with RA. Given the modifiable nature of circulating mineral status, these findings warrant further investigation for OA prevention strategies.

This study aimed to identify regional asymmetry in dopaminergic and serotoninergic dysfunction in degenerative parkinsonisms, using dopamine transporter single-photon emission computed tomography images.

This study included 213 consecutive participants (Parkinson's disease [n=111], dementia with Lewy bodies [n=64], progressive supranuclear palsy with Richardson's syndrome [n=18], and healthy participants [n=20]) who underwent both magnetic resonance imaging and
I-labelled 2β-carbomethoxy-3β-(4-iodophenyl)-N-(3-fluoropropyl) nortropane single-photon emission computed tomography/computed tomography. Using normalized specific binding ratio images, we created voxel-wise regional asymmetry index images to identify the regional specific pattern of regional asymmetries in degenerative parkinsonisms.

Compared with healthy controls, patients with Parkinson's disease showed a regional asymmetry index increase in the nigrostriatal dopaminergic pathway, and those with dementia with Lewy bodies showed a regional asymmetry index increase confined to the bilateral caudate. Individuals with progressive supranuclear palsy exhibited a distinct regional asymmetry index increase in the pallido-subthalamic pathway. CCS-1477 manufacturer Notably, the regional asymmetry index increase in the subthalamic nucleus was significantly greater in progressive supranuclear palsy than in Parkinson's disease.

The current study revealed distinctive regional asymmetry in dopaminergic and serotoninergic dysfunction in degenerative parkinsonisms. The present findings highlight the potential application of visual diagnosis in degenerative parkinsonisms.

To evaluate the association between malignancy and frequently positive paraneoplastic antibodies.

A retrospective cohort study was carried out for all patients who received paraneoplastic antibody testing in 2013-2014 at a tertiary referral center. Available medical records on included patients were reviewed through July 2020. Patients were divided into antibody positive and negative subgroups. Focused analysis was performed on the subgroup of patients who received testing via a commonly used antibody panel.

A total of 1860 patients (the full cohort) received 19,323 antibody testing via panel or individual antibody testing, and were followed-up for a mean period of 36.2months (range 0-83months). Altogether 229 antibodies in 196 patients were positive, and 9 (3.9%) in 7 patients were against onconeuronal antigens. The remaining 220 (96.1%) were positive for mostly antibodies against cell surface or synaptic antigens. A total of 1161 patients received Mayo Clinic paraneoplastic antibody panel tests (the panel cohort), and 14.9% (173) of these patients possessed one or more positive antibodies. For the panel cohort, no difference was found between antibody positive and negative groups with respect to the prevalence of previously existing malignancy (15.6% versus 16.6%, p=0.745) or incidence of new malignancy (4.0% vs. 3.7%, p=0.848) during the follow-up period. No difference was observed in the incidence of new malignancy during follow-up between the antibody positive and negative groups for the 7 most frequently positive antibodies.

The presence of frequently positive antibodies, mostly to cell surface or synaptic antigens, is not clearly associated with the development of malignancy in the subsequent three years.

To determine the feasibility of pre-treatment primary tumor FDG-PET and DWI-MR imaging parameters in predicting HPV status and the second aim was to assess the feasibility of those imaging parameters to predict response to therapy.

We retrospectively analyzed primary tumors in 33 patients with proven OPSCC. PET/MRI was performed before and 6months after chemo-radiotherapy for assessing treatment response. PET Standardized uptake value (SUVmax), total lesion glycolysis (TLG), metabolic tumor volume (MTV), and apparent diffusion coefficient (ADC) from pre-treatment measurements were assessed and compared to the clinicopathological characteristics (T stages, N stages, tumor grades, HPV and post-treatment follow up). HPV was correlated to the clinicopathological characteristics.
