AI Article Synopsis
- The study focuses on using electrospinning to create superhydrophobic fibers by optimizing various parameters, like voltage and flow rate.
- The work specifically applies this technique to coat aluminum alloy (60661T6) with polyvinyl chloride (PVC), which is naturally hydrophobic.
- It is notable for being the first to use a design of experiments (DoE) approach to enhance the performance of superhydrophobic and anticorrosive surfaces created from PVC through detailed analysis of coating characteristics such as fiber diameter and surface roughness.
Article Abstract
In this work, the electrospinning technique is used for the fabrication of electrospun functional fibers with desired properties in order to show a superhydrophobic behavior. With the aim to obtain a coating with the best properties, a design of experiments (DoE) has been performed by controlling several inputs operating parameters, such as applied voltage, flow rate, and precursor polymeric concentration. In this work, the reference substrate to be coated is the aluminum alloy (60661T6), whereas the polymeric precursor is the polyvinyl chloride (PVC) which presents an intrinsic hydrophobic nature. Finally, in order to evaluate the coating morphology for the better performance, the following parameters-such as fiber diameter, surface roughness (Ra, Rq), optical properties, corrosion behavior, and wettability-have been deeply analyzed. To sum up, this is the first time that DoE has been used for the optimization of superhydrophobic or anticorrosive surfaces by using PVC precursor for the prediction of an adequate surface morphology as a function of the input operational parameters derived from electrospinning process with the aim to validate better performance.

Division of Neurosurgery, Tohoku Medical and Pharmaceutical University, Sendai, Japan.
Background: The authors report the first case of thoracic interdural spinal cysts presenting as radiculopathy attributed to overdrainage-related cervical venous plexus enlargement. This case emphasizes the importance of considering interdural spinal cysts and cerebrospinal fluid overdrainage in the differential diagnosis of radiculopathy.
Observations: A 37-year-old male patient with a history of orthostatic headache presented with bilateral deltoid muscle atrophy consistent with C5 radiculopathy.

Pain Catastrophizing and Substance Misuse: A Scoping Review of the Literature.
Harv Rev Psychiatry
January 2025
From McLean Hospital (Drs. Bailey and McHugh, and Mss. Bichon and Friree Ford), Belmont, MA; Harvard Medical School (Drs. Bailey and McHugh); Brandeis University (Ms. Lesser).
Background: Pain catastrophizing, or the interpretation of pain as unbearable or intolerable, can increase pain-related anxiety and severity. High levels of pain catastrophizing have also been linked to substance use, particularly for substances with analgesic properties. Importantly, behavioral treatments can reduce pain catastrophizing, making them promising interventions for mitigating pain-related substance use.

Learning Objective: After participating in this CME activity, the psychiatrist should be better able to:• Explain current understanding of the relationship between chronic benzodiazepine use and dementia.
Background: Chronic use of benzodiazepines (BZ) for managing conditions such as anxiety disorders, depression, sleep disorders, and other chronic diseases is widespread; yet, there is considerable controversy regarding its potential links to dementia risk. This systematic review and meta-analysis aims to clarify this relationship by synthesizing and analyzing the available evidence to provide a clearer understanding of whether prolonged BZ use contributes to developing dementia.

Purpose: We aimed to clarify how the horizontal force-velocity (Fvh) relationship during over-ground sprint running differs with horizontal resistance loads and profiling methods (multiple- and single-trial methods).
Methods: Twelve males performed sprint running (one unresisted and five resisted) using a motorized loading device. During the trials, the ground reaction forces at every step were obtained using a 50 m force plate system.
