Background Previous research indicates low disposal rates of excess postoperative narcotics, leaving them available for diversion or abuse. This study examined the effect of introducing a portable disposal device on excess opiate opioid disposal rates after lower extremity orthopaedic surgery. Methods This was a single site randomized control trial within an outpatient orthopaedic clinic. All patients 18 years or older, undergoing outpatient foot and ankle surgery between December 1, 2017 and August 1, 2018 were eligible. Patients were prospectively enrolled and randomized to receive standard opioid disposal instructions or a drug deactivation device at 2-week postoperative appointments. Participants completed an anonymous survey at 6-week postoperative appointments. Results Of the 75 patients surveyed, 68% (n = 26) of the experimental group and 56% (n = 21) of the control group had unused opioid medication. Of these, 84.6% of patients who were given Deterra Drug Deactivation System deactivation pouches safely disposed of excess medication, compared with 38% of controls (P = .003). When asked if they would use a disposal device for excess medication in the future, 97.4% (n = 37) of the experimental and 83.8% (n = 31) of the control group reported that they would. Conclusions Providing a portable disposal device with postoperative narcotic prescriptions may increase safe disposal rates of excess opioid medication following lower extremity orthopaedic surgery.

<b><i>Background:</i></b> There is still no clinical evidence available to support or to oppose corticosteroid treatment for coronavirus disease 2019 (COVID-19) pneumonia. <b><i>Objective:</i></b> To investigate the efficacy and safety of corticosteroid given to the hospitalized patients with COVID-19 pneumonia. <b><i>Methods:</i></b> This was a prospective, multicenter, single-blind, randomized control trial. Adult patients with COVID-19 pneumonia who were admitted to the general ward were randomly assigned to either receive methylprednisolone or not for 7 days. The primary end point was the incidence of clinical deterioration 14 days after randomization. <b><i>Results:</i></b> We terminated this trial early because the number of patients with COVID-19 pneumonia in all the centers decreased in late March. Finally, a total of 86 COVID-19 patients underwent randomization. There was no difference of the incidence of clinical deterioration between the methylprednisolone group and control group (4.8 vs. 4.8%, <i>p</i> = 1.000). The duration of throat viral RNA detectability in the methylprednisolone group was 11 days (interquartile range, 6–16 days), which was significantly longer than that in the control group (8 days [2–12 days], <i>p</i> = 0.030). There were no significant differences between the 2 groups in other secondary outcomes. Mass cytometry discovered CD3<sup>+</sup> T cells, CD8<sup>+</sup> T cells, and NK cells in the methylprednisolone group which were significantly lower than those in the control group after randomization (<i>p</i> &#x3c; 0.05). <b><i>Conclusions:</i></b> From this prematurely closed trial, we found that the short-term early use of corticosteroid could suppress the immune cells, which may prolong severe acute respiratory syndrome coronavirus 2 shedding in patients with COVID-19 pneumonia. <b><i>Trial Registration:</i></b> ClinicalTrials.gov, NCT04273321.

This non-randomized control group intervention study was conducted to determine the effect of preoperative video based pain training on postoperative pain and analgesic use in patients undergoing total knee arthroplasty. During the study, the patients in the control ( n = 40) received routine care and the patients in the intervention group ( n = 40) received video based pain training. İt was determined that the mean postoperative pain scores of the intervention group were significantly lower and their pain management was better compared to the control group ( p < .05). The intervention group was found to use significantly less paracetamol on operation day compared to the control group ( p < .05). The intervention group was determined to benefit from non-pharmacological methods more than the control group did ( p < .05). Providing video based pain training to patients undergoing total knee arthroplasty is recommended since it reduces postoperative pain levels and increases the use of non-pharmacological pain control methods.

Undernutrition and hidden hunger threaten the survival, growth, and development of children, young people, economies, and nations. Inappropriate complementary feeding practice due to poor maternal knowledge and awareness in combination with low income and infectious disease is the contributing factor for child undernutrition. Hence, this study was aimed at determining the effect of nutrition education on improving the knowledge and practice of complementary feeding of the mothers with 6- to 23-month old children in daycare centers of Hawassa Town, Southern Ethiopia. An institution-based randomized control trial design was employed. Daycare centers were randomly allocated for the intervention group and the control group. Among the total daycare centers in the town, five were assigned to receive nutrition education and the rest five for the control group (CG). The simple random sampling technique used to select individual participants from each daycare center. Two hundred (200) mother-child pairs (100 for each group) were recruited. Sociodemographic and economic variables were collected by the structured questionnaire. Knowledge of appropriate complementary feeding was assessed by seven knowledge questions. Appropriate complementary feeding practice was assessed by adapting Alive and Thrive Infant and Young Child Feeding (IYCF) practice guidelines. Nutrition education was given for four consecutive months by using Alive and Thrive IYCF guidelines. Data were analyzed by the SPSS software program version 20. The chi-squared test was used to test the significant differences in the proportion of good knowledge and good practice of complementary feeding and good dietary diversity between two groups. The independent t test was used to test the significant differences in mean dietary diversity between two groups. At 95% confidence interval, p<0.05 was considered statistically significant. The results revealed that the proportion of mothers with good knowledge of appropriate complementary feeding was increased from 59% at pretest to 96% at posttest and the appropriate complementary feeding practice was improved from 54% at pretest to 86% at posttest in IG. There was no change in the knowledge and practice of complementary feeding practice in CG after four months. The proportion of mothers with good complementary knowledge was 54% both at pretest and at posttest and good complementary feeding practice was 51% and 52% at pre- and posttest in CG, respectively. There was no significant difference (p>0.05) on complementary feeding knowledge and practice between two groups at pretest, while the difference was highly significant (p<0.05) at the posttest. In conclusion, providing nutrition education improved the appropriate complementary feeding knowledge and practice of mothers. In recommendation, government and other partners working on sustainable child nutrition reduction should focus on the nutrition education to improve the knowledge and appropriate complementary feeding practice including daycare centers.
