This study examines the distribution and trends in suicide death rates among male adults aged ≥65 years in the U.S. from 1999 to 2018.

Suicide mortality data were derived from Multiple Cause of Death from the Center for Disease Control and Prevention's Wide-ranging Online Data for Epidemiologic Research database. Suicides were identified from the underlying causes of death. Joinpoint regression examined the distribution and shift in suicide age-adjusted death rates overall and by age groups, race/ethnicity, method of suicide, and urbanicity. Analyses were conducted in 2020.

Between 1999 and 2018, a total of 106,861 male adults aged ≥65 years died of suicide (age-adjusted rate=31.4 per 100,000 population, 95% CI=31.2, 31.6). Suicide rates showed a V-shaped trend. They were declining annually by 1.8% (95% CI= -2.4, -1.2); however, starting in 2007, there was a shift upward, increasing significantly by 1.7% per year for the next decade (95% CI=1.0, 1.6). Suicide rates were highest among those aged ≥85 years (48.8 per 100,000 population with an upward shift in 2008), Whites (35.3 per 100,000 population with an upward shift in trend in 2007), and the most rural communities (39.0 per 100,000 population). Most suicides were due to firearms (78.3% at a rate of 24.7 per 100,000 population), especially in rural areas, and shifted upward after 2007.

Increases in suicide rates among male older adults in the U.S., particularly after the 2007-2008 economic recession, are concerning. Tailored suicide prevention intervention strategies are needed to address suicide-related risk factors.

This systematic review aimed to evaluate the epidemiologic profile, screen for possible risk factors, and evaluate the spectrum of clinical characteristics of oral squamous cell carcinoma (OSCC) around dental implants (DIs).

The systematic review was performed according to the Preferred Reporting Items for Systematic Reviews and Meta- Analyses statement.

Thirty-three articles met the eligibility criteria. In total, the sample consisted of 63 patients, and women comprised the majority (55.5%). The mean age of patients was 66.7 years. Oral potentially malignant disorders were reported in 46% of patients, of which 65.5% occurred in women. The most common lesion found in women was oral lichen planus (52.6%). In 88.8% of patients OSCC around DIs occurred in the mandible, and the most common clinical appearance of the lesions was an exophytic mass (46%). Most of these lesions were initially treated as peri-implantitis.

Most patients with OSCC around DIs were women without known risk factors. It is important to emphasize that these lesions may present clinical and radiographic features that could resemble peri-implantitis, which can lead to delay in the diagnosis and subsequent treatment.

The aim of this study was to compare the diagnostic performance of convolutional neural networks (CNNs) with the performance of human observers for the detection of simulated periapical lesions on periapical radiographs.

Ten sockets were prepared in bovine ribs. Periapical defects of 3 sizes were sequentially created. Periapical radiographs were acquired of each socket with no lesion and with each lesion size with a photostimulable storage phosphor system. Radiographs were evaluated with no filter and with 6 image filter settings. A CNN architecture was set up using Keras-TensorFlow. Separate CNNs were evaluated for randomly sampled training/validation data and for data split up by socket (5-fold cross-validation) and filter (7-fold cross-validation). CNN performance on validation data was compared with that of 3 oral radiologists for sensitivity, specificity, and area under the receiver operating characteristic curve (ROC-AUC).

Using random sampling, the CNN showed perfect accuracy for the validation data. When data were split up by socket, the mean sensitivity, specificity, and ROC-AUC values were 0.79, 0.88, and 0.86, respectively; when split up by filter, they were 0.87, 0.98, and 0.93, respectively. For radiologists, the values were 0.58, 0.83, and 0.75, respectively.

CNNs show promise in periapical lesion detection. The pretrained CNN model yielded in this study can be used for further training on larger samples and/or clinical radiographs.

However, pancytopenia represents a rare but serious complication from SARS-CoV2 infection. While lymphopenia is a common finding, concomitant acute anemia and thrombocytopenia are not commonly reported. We describe a novel case of SARS-CoV2 pancytopenia in a 40-year-old male without active risk factors for cell line derangements but subsequent critical illness.
After experiencing an unexpected slip perturbation, individuals' behavioral performance can be classified into three categories recovery, feet-forward fall, and split fall. Researchers are uncertain whether these differences in slip outcomes are due to distinct strategies or part of a single strategy.

Whether older adults with different behavioral outcomes during their novel slip have different kinematic synergies?

The kinematic synergies were extracted from segment angles in 87 participants using principal component analysis (PCA). The first two principal components (PC1 and PC2) in pre-slip, early-reactive, and late-reactive phases were compared across different slip outcomes.

Results showed that the kinematic synergies in pre-slip and early-reactive phases are highly consistent among the three outcomes (recovery, split fall, and feet-forward fall). For the late-reactive phase, both split falls and feet-forward falls showed different kinematics synergies from recoveries.

Our findings indicated that a single strategy might be used for different slip outcomes in the pre-slip and early-reactive phases, while distinct strategies were used by fallers compared to recovered individuals.
