As aging comes, an increased prevalence of medical maladies and chronic pain independently or interactively disrupt sleep, which in turn can exacerbate either one. Furthermore, anxiety about pain can further negatively impact sleep. Fortunately, good quality sleep can improve pain management. Because benzodiazepine receptor agonists (including the “Z” drugs) can reduce anxiety and improve sleep, they seem a convenient choice. However, their use in this population, particularly for more than short-term (guidelines range from 2 to 6 weeks max), is not recommended because of increased likelihood of falls, further disruption of sleep, dependence, and problems with discontinuation (withdrawal). Besides, this population is often likely to take concomitant medication for pain or other central nervous system depressants leading to potentially serious and even life-threatening interactions involving synergistic amplification of respiratory depression (opioids being a particularly dangerous interaction). Therefore, insomnia in older adults should ideally be treated with a non-benzodiazepine receptor agonist;if indicated, they may be used, but should be closely monitored and tapered to avoid long-term adverse problems (direct or from withdrawal). Older adult patients with insomnia may be more optimally treated with sleep aids that do not interact with the GABAA receptor.

Opioids are a treatment option for a variety of chronic pain conditions. But long-term opioid use can be associated with side effects, including hypogonadism. Opioid-induced hypogonadism (OIhG) is associated with the alteration of the hypothalamic-pituitary-gonadal axis (HPG). In males, hypogonadism can result in erectile dysfunction, reduced libido, fatigue, worsening mood, and increased risk of osteoporosis;in females, it can result in changes in the menstrual cycle and reduced libido, among other effects. A current treatment option for these patients is hormone replacement therapy. In this report, we discuss the problem of opioid-induced hypogonadism, and the therapeutic approach and the potential complications of treating pain patients using hormone replacement therapy.

The response of an optical strain sensor based on the fiber Bragg grating is theoretically analyzed with a different approach of that found usually in the literature. In this model, geometrical changes suffered by the grating itself are taken into account. The results are compared with those from experiments, showing very good agreement.

The scope of the present research aims at demonstrating the 3D printing use in the manufacturing of microchannels for chemical process applications. A comparison among digital model processing applications for 3D print(slicers) and a print layer thickness analysis were performed. The 3D print fidelity was verified in several devices, including the microchannels’ printing with and without micromixer zones. In order to highlight the 3D print potential in Chemical Engineering, the biodiesel synthesis was also carried out in a millireactor manufactured by 3D printing. The millireactor operated under laminar flow regime with a total flow rate of 75.25 ml·min^-1(increment of about 130 times over traditional microdevices used for biodiesel production).The printed millireactor provided a maximum yield of Ethyl Esters of 73.51% at 40 ℃, ethanol:oil molar ratio of7 and catalyst concentration of 1.25 wt% and residence time about 10 s. As a result of flow rate increment attained in the millireactor, the number of required units for scaling-up the chemical processes is reduced. Using the approach described in the present research, anyone could produce their own millireactor for chemical process in a simple way with the aid of a 3D printer.
