- Dental fear is a common and widespread problem, which can cause severe stress. Even so, most patients with dental fear undergo regular dental treatment in spite of their fear and many enjoy good oral health. The aim of this study was to obtain a deeper understanding of how patients with dental fear manage to undergo dental treatment. Fourteen patients with dental fear, who undergo regular dental care, were interviewed. Qualitative analysis of the transcribed interviews was performed according to the principles of grounded theory. A conceptual framework was generated, and the main concern was identified as 'making dental care possible - a mutual affair'. Four additional categories explained how patients handled their dental fear and how dental care became possible. The strategies were labelled 'taking part in a mental wrestling match', 'trust-filled interaction with dental staff', 'striving for control' and 'seeking and/or receiving social support'. The results showed that making dental care possible for patients with dental fear is a mutual challenge that requires interplay between dental staff and patients, involving verbal and non-verbal communication reflecting respect, attention, and empathy. Moreover, a balance between nearness and distance and between professional and personal treatment is required.

- IMPORTANCE Lack of arachidonic acid (AA) and docosahexaenoic acid (DHA) after extremely preterm birth may contribute to preterm morbidity, including retinopathy of prematurity (ROP). OBJECTIVE To determine whether enteral supplementation with fatty acids from birth to 40 weeks' postmenstrual age reduces ROP in extremely preterm infants. DESIGN, SETTING, AND PARTICIPANTS The Mega Donna Mega trial, a randomized clinical trial, was a multicenter study performed at 3 university hospitals in Sweden from December 15, 2016, to December 15, 2019. The screening pediatric ophthalmologists were masked to patient groupings. A total of 209 infants born at less than 27 weeks' gestation were tested for eligibility, and 206 infants were included. Efficacy analyses were performed on as-randomized groups on the intention-to-treat population and on the per-protocol population using as-treated groups. Statistical analyses were performed from February to April 2020. INTERVENTIONS Infants received either supplementation with an enteral oil providing AA (100mg/kg/d) and DHA (50mg/kg/d) (AA:DHA group) or no supplementation within 3 days after birth until 40 weeks' postmenstrual age. MAIN OUTCOMES AND MEASURES The primary outcomewas severe ROP (stage 3 and/or type 1). The secondary outcomes were AA and DHA serum levels and rates of other complications of preterm birth. RESULTS A total of 101 infants (58 boys [57.4%]; mean [SD] gestational age, 25.5 [1.5] weeks) were included in the AA:DHA group, and 105 infants (59 boys [56.2%]; mean [SD] gestational age, 25.5 [1.4] weeks) were included in the control group. Treatment with AA and DHA reduced severe ROP compared with the standard of care (16 of 101 [15.8%] in the AA:DHA group vs 35 of 105 [33.3%] in the control group; adjusted relative risk, 0.50 [95% CI, 0.28-0.91]; P =.02). The AA:DHA group had significantly higher fractions of AA and DHA in serum phospholipids compared with controls (overall mean difference in AA:DHA group, 0.82 mol% [95% CI, 0.46-1.18 mol%]; P <.001; overall mean difference in control group, 0.13 mol% [95% CI, 0.01-0.24 mol%]; P =.03). There were no significant differences between the AA:DHA group and the control group in the rates of bronchopulmonary dysplasia (48 of 101 [47.5%] vs 48 of 105 [45.7%]) and of any grade of intraventricular hemorrhage (43 of 101 [42.6%] vs 42 of 105 [40.0%]). In the AA:DHA group and control group, respectively, sepsis occurred in 42 of 101 infants (41.6%) and 53 of 105 infants (50.5%), serious adverse events occurred in 26 of 101 infants (25.7%) and 26 of 105 infants (24.8%), and 16 of 101 infants (15.8%) and 13 of 106 infants (12.3%) died. CONCLUSIONS AND RELEVANCE This study found that, compared with standard of care, enteral AA:DHA supplementation lowered the risk of severe ROP by 50% and showed overall higher serum levels of both AA and DHA. Enteral lipid supplementation with AA:DHA is a novel preventive strategy to decrease severe ROP in extremely preterm infants.

Mitochondrial function and membrane integrity: an in vitro comparison between six commonly used opioids
-
Other publication (other academic/artistic)abstract
- Introduction: There is an ongoing opioid crisis in the United States where the illicit and non-medical use of prescription opioids is associated with an increasing number of overdose deaths. Few studies have investigated the effects of opioid-induced effects on cell viability, and comparative studies are scarce. Here we examine the toxic effect on cell viability from six commonly used opioids; methadone, morphine, oxycodone, hydromorphone, ketobemidone, and fentanyl with respect to mitochondrial and membrane function in vitro. Methods: The opioids were tested in four different cell cultures; primary cortical cell cultures, human neuroblastoma SH-SY5Y cells, and both differentiated and undifferentiated neuroblastoma/glioma hybrid NG108-15 cells. Results: The six different opioids displayed the same trend of reduced cell viability in all four cell cultures. The ranking of opioids, with respect to reduced cell viability were as follows; methadone, fentanyl, ketobemidone, oxycodone, hydromorphone, and morphine. Conclusion: Methadone was ranked as the most toxic opioid closely followed by fentanyl. Ketobemidone and oxycodone had modest effects while both hydromorphone and morphine only displayed little to no negative impact on cell viability.
