ange in the choroidal thickness. Further studies are essential to evaluate choroidal changes after the cataract surgery in diabetic eyes.BACKGROUND Exposures to perfluoroalkyl substances (PFAS) have shown positive associations with serum lipids in previous studies. While many studies on lipids investigated associations with perfluorooctane sulfonic acid (PFOS) and perfluorooctanoic acid (PFOA), there are only a few studies regarding other PFAS, such as perfluorohexane sulfonic acid (PFHxS). The purpose of the current study is to investigate if associations with serum lipids were present, not only for serum PFOS and PFOA, but also for PFHxS, and if the associations with PFAS remained also in a comparison based only on residency in areas with contrasting exposure to PFAS. METHODS 1945 adults aged 20-60 were included from Ronneby, Sweden, a municipality where one out of two waterworks had been heavily contaminated from aqueous fire-fighting foams, and from a nearby control area. The exposure was categorized based on either been living in areas with contrasting PFAS exposure or based on the actual serum PFAS measurements. Regression analyses of serum lipids were fitted against serum PFAS levels, percentile groups, smooth splines and between exposed and reference areas, adjusting for age, sex and BMI. RESULTS Drinking water contamination caused high serum levels of PFOS (median 157 ng/ml) and PFHxS (median 136 ng/ml) and PFOA (median 8.6 ng/ml). These serum PFAS levels in the exposed groups were 5 to 100-fold higher than in the controls. In this population with mixed PFAS exposure, predominantly PFOS and PFHxS, PFAS exposure were positively associated with serum lipids. This was observed both when quantifying exposure as contrast between exposed and controls, and in terms of serum PFAS. Due to high correlations between each PFAS, we cannot separate them. CONCLUSIONS In conclusion, the present study provides further evidence of a causal association between PFAS and serum lipids, especially for PFHxS.BACKGROUND Down syndrome is characterized by a variety of dysmorphic features and congenital malformations, such as congenital heart disease, gastrointestinal disease, and other conditions like leukemia and autoimmune disorders. Patients with Down syndrome are highly prone to respiratory tract infections, which might be fatal to them. However, there are only few available data on patients diagnosed with Down syndrome and agammaglobulinemia. In this report, we describe a case of successful prevention of post-dental treatment complications (e.g., pneumonia and other bacterial infections) in a patient with Down syndrome and agammaglobulinemia. CASE PRESENTATION A 43-year-old man with Down syndrome, untreated agammaglobulinemia, and a history of recurrent pneumonia, was referred to our clinic for tooth mobility. To reduce the risk of post-operative infections, gammaglobulin treatment and prophylactic administration of antibiotics was scheduled before the dental procedure. Furthermore, the dental treatment, which included a filling and extractions, was conducted under general anesthesia and with the supervision of a hematologist. The dental procedures were successfully performed without any post-operative infection, and the patient is undergoing follow-up care. CONCLUSIONS The purpose of this case report was to recommend a close liaison between physicians and dentists who may encounter a similar case, and to emphasize the importance of improving oral health of immunodeficient patients to prevent infections caused by oral microbial flora.BACKGROUND HIV viral suppression is associated with health benefits for people living with HIV and a decreased risk of HIV transmission to others. The objective was to identify demographic, psychosocial, provider and neighborhood factors associated with sustained viral suppression among gay, bisexual, and other men who have sex with men. METHODS Data from adult men who have sex with men (MSM) enrolled in the Miami-Dade County Ryan White Program (RWP) before 2017 were used. Sustained viral suppression was defined as having an HIV viral load less then  200 copies/ml in all viral load tests in 2017. Three-level (individual, medical case management site, and neighborhood) cross-classified mixed-effect models were used to estimate adjusted odds ratios (aOR) and 95% confidence intervals (CI) for sustained viral suppression. click here RESULTS Of 3386 MSM, 90.8% were racial/ethnic minorities, and 84.4% achieved sustained viral suppression. The odds of achieving sustained viral suppression was lower for 18-24 and 25-34 year-olfurther.BACKGROUND Cell-free protein expression has become a widely used alternative of in vivo, cell-based systems in functional and structural studies of proteins. The wheat germ-based method outstands from the commercially available eukaryotic in vitro translation systems by its flexibility, high translation efficiency and success rate of properly folded eukaryotic protein synthesis. The original T7 promoter containing pEU3-NII vector was improved previously by addition of a ligation-independent cloning site, His6- and GST-tags, and a TEV protease cleavage site to facilitate the creation of recombinant plasmids, permit affinity purification, and enable production of purified, tag-free target proteins, respectively. RESULTS Here, we describe a further development of pEU3-NII vector by inserting the rare-cutting, NotI restriction enzyme cleavage site to simplify vector linearization step prior to in vitro transcription. Additionally, His12, FLAG, and Halo affinity tag coding vectors have been created to increase detection sensitivity, specificity of interaction studies, and provide covalently linkable ligands for pull-down assays, respectively. Finally, the presented GST-His6, and GST-biotin double-tagging vectors could broaden the range of possibilities of protein-protein interaction studies. CONCLUSIONS The new generation of pEU3-NII vector family allows a more rapid production of translationally active mRNA and wheat germ cell-free expression of target proteins with a wide variety of affinity tags thus enables designing flexible and diverse experimental arrangement for in vitro studies of proteins.
