Background: The use of anticholinergics has been on the rise. With the increase in population longevity, more medication-related cognitive impairments (ACIs) have been reported. These impairments result in significant morbidities. We present a case that stresses on the importance of being vigilant when prescribing anticholinergic medications, especially in the elderlies. Case Report: A case of ACIs related to the use of tiotropium bromide/olodaterol (Stiolto Respimat) is being reported in a 71-year-old white man with COPD. Treatment with budesonide 180 mcg/actuation, and tiotropium bromide/olodaterol (Stiolto Respimat) inhalers was initiated. Two days after initiating treatment, the patient developed ACIs which manifested by gait imbalance, short-term memory dysfunction, inability to remember his family members, or to take his medications. Tiotropium bromide/olodaterol (Stiolto Respimat) was discontinued. After three days, a full recovery of ACIs was reported. A month later, due to worsening dyspnea, the patient self-resumed the medicine. Similar ACIs were reported within two days of resuming treatment. Tiotropium bromide/olodaterol (Stiolto Respimat) was discontinued indefinitely. Full recovery of ACIs was reported. Conclusion: ACIs should be noted as a significant side effect of tiotropium bromide/olodaterol. Clinicians should be vigilant, when prescribing anticholinergic medications to elderlies.

Background: Varenicline, which is derived from the cytisine compound, is used to assess in smoking cessation. Sleep driving (SD) is often classified as a variant of somnambulism. Although, somnambulism has been reported as a side effect of varenicline, varenicline-induced sleep driving (VISD) has not been reported. Case Report: A 56-year-old man with a history of 35 pack year smoking who presented for smoking cessation counseling. Treatment with varenicline was initiated. In the following night, the patient drove to a shopping center and woke up in his car. Varenicline was discontinued. SD has not been reported in the following nights. In a repeated attempt to stop smoking, treatment with varenicline was resumed by the patient. SD reoccurred in the following night. Varenicline was discontinued indefinitely, and SD has not been reported.

For unachievable tracking problems, where the system output cannot precisely track a given reference, achieving the best possible approximation for the reference trajectory becomes the objective. This study aims to investigate solutions using the Ptype learning control scheme. Initially, we demonstrate the necessity of gradient information for achieving the best ***, we propose an input-output-driven learning gain design to handle the imprecise gradients of a class of uncertain systems. However, it is discovered that the desired performance may not be attainable when faced with incomplete *** address this issue, an extended iterative learning control scheme is introduced. In this scheme, the tracking errors are modified through output data sampling, which incorporates lowmemory footprints and offers flexibility in learning gain *** input sequence is shown to converge towards the desired input, resulting in an output that is closest to the given reference in the least square sense. Numerical simulations are provided to validate the theoretical findings.
