- Department of Occupational and Environmental Medicine, Lund University, Sweden. Methylmercury in serum (S-MeHg) was assessed from serum concentrations of total (S-TotHg) and inorganic mercury (S-InoHg), determined by cold vapor-atomic absorption spectrometry. The samples were collected from 135 women on two occasions, in 1968-1969 and 1980-1981. In a subgroup of 29 women, an association was found between S-MeHg and the amount of fish consumed in 1968-1969 (r = 0.38, P = 0.04). The association was stronger (r = 0.50; P = 0.006) when the individuals' mean S-MeHg from 1968-1969 and 1980-1981 were plotted vs fish consumption 1968-1969. In the group, as a whole, there was an association between S-InoHg and number of dental amalgam surfaces, in both 1968-1969 (r = 0.48, P = 0.0001) and 1980-1981 (r = 0.57, P < 0.0001). The S-InoHg increased by approximately 0.1 nmol/L per amalgam tooth surface, corresponding to an uptake of approximately 0.2 microgram/day per amalgam surface, but with considerable interindividual differences. The levels were lower in 1980-1981 than in 1968-1969 for both MeHg and InoHg. The medians and ranges (nmol/L) were for MeHg 1968-1969: 3.6 (0.3-11.9); MeHg 1980-1981, 2.0 (-0.4-8.7); InoHg 1968-1969, 3.3 (0.7-11.8); InoHg 1980-1981, 1.7 (0.1-11.8); TotHg 1968-1969, 7.2 (1.9-18.8); and TotHg 1980-1981, 3.9 (1.0-14.2). The decrease in S-MeHg is probably due to a decreased consumption of MeHg via contaminated fish. The decrease in S-InoHg may reflect a decrease in environmental exposure, but the possibility of contamination of the 1968-1969 samples at sampling and/or storage cannot be excluded.

- OBJECTIVE: Atherosclerotic lesions have regions that are hypoxic. Because the lesion contains macrophages that are loaded with lipid, we investigated whether hypoxia can influence the accumulation of lipids in these cells. METHODS AND RESULTS: Exposure of human macrophages to hypoxia for 24 hours resulted in an increased formation of cytosolic lipid droplets and an increased accumulation of triglycerides. Exposure of the macrophages to oxidized low-density lipoprotein (oxLDL) increased the accumulation of cytosolic lipid droplets because of an increase in cellular cholesterol esters. The accumulation of lipid droplets in oxLDL-treated cells was further increased after hypoxia, caused by an increased level of triglycerides. Expression analyses combined with immunoblot or RT-PCR demonstrated that hypoxia increased the expression of several genes that could promote the accumulation of lipid droplets. Hypoxia increased the mRNA and protein levels of adipocyte differentiation-related protein (ADRP). It is well known that an increased expression of ADRP increases the formation of lipid droplets. Hypoxia decreased the expression of enzymes involved in beta-oxidation (acyl-coenzyme A synthetase and acyl-coenzyme A dehydrogenase) and increased the expression of stearoyl-coenzyme A desaturase, an important enzyme in the fatty acid biosynthesis. Moreover, exposure to hypoxia decreased the rate of beta-oxidation, whereas the accumulation of triglycerides increased. CONCLUSIONS: The results demonstrate that exposure of human macrophages to hypoxia causes an accumulation of triglyceride-containing cytosolic lipid droplets. This indicates that the hypoxia present in atherosclerotic lesions can contribute to the formation of the lipid-loaded macrophages that characterize the lesion and to the accumulation of triglycerides in such lesions.

- Background Electroconvulsive therapy (ECT) effectively treats severe depression, but not all patients remit. The aim of the study was to identify clinical factors that associate with ECT-induced remission in a community setting. Methods Depressed patients who underwent ECT in 2011–2014 were identified from the Swedish National Quality Register for ECT. Remission was defined as self-rated Montgomery-Åsberg Depression Rating Scale scores of 0–10 after ECT. Other registers provided data on previous antidepressant use, comorbidities, and demographics. Results Of 1671 patients fulfilling the inclusion criteria, 42.8% achieved remission. Older age, education length over 9 years, psychotic symptoms, shorter duration of preceding antidepressant use, pulse width stimulus ≥ 0.50 ms, absence of substance use disorders, anxiety diagnosis, lamotrigine, and benzodiazepines, were associated with remission. Conclusions This study shows that psychotic subtype of depression and older age are clinically relevant predictors of a beneficial ECT effect. Additionally, ECT outcomes can be further improved by optimizing the treatment technique and concomitant medication. © 2017 The Author(s)
