We investigated whether the longitudinal relation between cognitive reserve accumulated across the lifespan and rate of cognitive decline over 6 years differed by the individual's degree of functional impairment.

We analyzed longitudinal data from 897 older adults (M = 74.33 years) tested on the Trail Making Test (TMT) in 2 waves 6 years apart.

There was a significant interaction of functional impairment with cognitive reserve on latent change in cognitive functioning. Specifically, with no functional impairment in the first wave of assessment, greater cognitive reserve accumulated across the lifespan significantly predicted a reduced cognitive decline over 6 years (i.e., smaller increase in TMT completion time). In contrast, with certain functional impairment (in at least some activities) in the first wave, greater cognitive reserve build-up predicted a steeper cognitive decline (i.e., larger increase in TMT completion time).

Individuals with greater cognitive reserve accumulated across the lifespan show a reduced cognitive decline if they still have relatively little functional impairment, while they will show a steeper decline (compared to individuals with less cognitive reserve) as soon as functional impairment becomes substantial.

The main aim of the fetal surgery of myelomeningocele (MMC) is the improvement in prognosis for children with this defect and at the same time high safety of the procedure for mother and fetus.

The aim of the study was to determine the effectiveness of alternative hysterotomy technique for fetal surgery of MMC in prevention of essential perinatal complications.

Forty-nine pregnant women diagnosed with fetal MMC (fMMC) who underwent classic hysterotomy without the use of stapler formed the study cohort. Two cases of intrauterine fetal death or neonatal death in the immediate perioperative period in the study group (SG) were excluded from further analyses. In the historical control group (46 patients) from our center hysterotomy was performed according to Management of Myelomeningocele Study (MOMS) protocol. The study cohort's outcomes were compared with the historical controls and with post-MOMS results in Children's Hospital of Philadelphia (CHOP) and Vanderbilt University Medical Center (VUMC).

In the SG we did not observe delivery before 30 weeks of gestation (0/47; 0%) and the incidence of chorionamniotic membrane separation (CMS, 3/47; 6%) and preterm premature rupture of membranes (PPROM, 7/47; 15%) was lower compared to the other groups. Preterm delivery as a result of uterine contractions occurred significantly less frequently in the SG (8/47; 17%). Fetal surgery with classic hysterotomy resulted in rare use of magnesium sulfate (3/47; 6%).

The alternative hysterotomy technique for fetal surgery of MMC results in low occurrences of CMS, PPROM, preterm delivery, and the rare use of tocolytics.

Asleep deep brain stimulation (DBS) for Parkinson's disease (PD) is being performed more frequently; however, motor outcomes and safety of asleep DBS have never been assessed in a prospective randomized trial.

We conducted a prospective, randomized, noncomparative trial to assess the motor outcomes of asleep DBS. Leads were implanted in the subthalamic nucleus (STN) according to probabilistic stereotactic coordinates with a surgical robot under O-arm© imaging guidance under either general anesthesia without microelectrode recordings (MER) (20 patients, asleep group) or local anesthesia with MER and clinical testing (9 patients, awake group).

The mean motor improvement rates on the Unified Parkinson's Disease Rating Scale Part III (UPDRS-3) between OFF and ON stimulation without medication were 52.3% (95% CI 45.4-59.2%) in the asleep group and 47.0% (95% CI 23.8-70.2%) in the awake group, 6 months after surgery. Except for a subcutaneous hematoma, we did not observe any complications related to the surgery. Three patients (33%) in the awake group and 8 in the asleep group (40%) had at least one side effect potentially linked with neurostimulation.

Owing to its randomized design, our study supports the hypothesis that motor outcomes after asleep STN-DBS in PD may be noninferior to the standard awake procedure.

Analysis of macroscopic, histopathological findings with clinical features was performed. All 3 deceased patients were Caucasian males (average age 61 years, range from 56 to 68 years). XL092 in vitro Using real-time polymerase chain reaction assay, the patients were confirmed (antemortem) to have severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection. Two patients were obese, and 1 patient had type 2 diabetes mellitus. The medical history of 1 patient included hemorrhagic pancreatitis, gangrenous cholecystitis, Acinetobacter baumanii sepsis, and cholecystectomy. Pulmonary embolism was diagnosed in 2 patients. At autopsy, in 1 case, the lungs showed bilateral interstitial pneumonia with diffuse alveolar damage (DAD), while in another case, interstitial pulmonary lymphoid infiltrates and enlarged atypical pneumocytes were present but without DAD. Microthrombi in lung vessels and capillaries were observed in 2 cases. This study revealed thrombotic complications of COVID-19 and interstitial pneumonia with DAD presence as the main autopsy findings in patients with SARS-CoV-2 infection that was confirmed antemortem with molecular tests. Autopsy studies using tissue sections handled in accordance with SARS-CoV-2 biosafety guidelines are urgently needed, especially in the case of subjects who were below the age of 60.
