Meningeal Lymphangiogenesis and Enhanced Glymphatic Activity in Mice with Chronically Implanted EEG Electrodes

Chronic electroencephalography (EEG) is a widely used tool for monitoring cortical electrical activity in experimental animals. Although chronic implants allow for high-quality, long-term recordings in preclinical studies, the electrodes are foreign objects and might therefore be expected to induce a local inflammatory response. Chronic electroencephalography (EEG) is a widely used tool for monitoring cortical electrical activity in experimental animals. Although chronic implants allow for high-quality, long-term recordings in preclinical studies, the electrodes are foreign objects and might therefore be expected to induce a local inflammatory response. We here analyzed the effects of chronic cranial electrode implantation on glymphatic fluid transport and in provoking structural changes in the meninges and cerebral cortex of male and female mice. Immunohistochemical analysis of brain tissue and dura revealed reactive gliosis in the cortex underlying the electrodes and extensive meningeal lymphangiogenesis in the surrounding dura. Meningeal lymphangiogenesis was also evident in mice prepared with the commonly used chronic cranial window. Glymphatic influx of a CSF tracer was significantly enhanced at 30 d postsurgery in both awake and ketamine-xylazine anesthetized mice with electrodes, supporting the concept that glymphatic influx and intracranial lymphatic drainage are interconnected. Altogether, the experimental results provide clear evidence that chronic implantation of EEG electrodes is associated with significant changes in the brain's fluid transport system. Future studies involving EEG recordings and chronic cranial windows must consider the physiological consequences of cranial implants, which include glial scarring, meningeal lymphangiogenesis, and increased glymphatic activity. SIGNIFICANCE STATEMENT This study shows that implantation of extradural electrodes provokes meningeal lymphangiogenesis, enhanced glymphatic influx of CSF, and reactive gliosis. The analysis based on CSF tracer injection in combination with immunohistochemistry showed that chronically implanted electroencephalography electrodes were surrounded by lymphatic sprouts originating from lymphatic vasculature along the dural sinuses and the middle meningeal artery. Likewise, chronic cranial windows provoked lymphatic sprouting. Tracer influx assessed in coronal slices was increased in agreement with previous reports identifying a close association between glymphatic activity and the meningeal lymphatic vasculature. Lymphangiogenesis in the meninges and altered glymphatic fluid transport after electrode implantation have not previously been described and adds new insights to the foreign body response of the CNS.
Does spatial awareness training affect anatomy learning in medical students?

Spatial ability (SA) is the cognitive capacity to understand and mentally manipulate concepts of objects, remembering relationships among their parts and those of their surroundings. Spatial ability provides a learning advantage in science and may be useful in anatomy and technical skills in health care. This study aimed to assess the relationship between SA and anatomy scores in first‐ and second‐year medical students. The training sessions focused on the analysis of the spatial component of objects' structure and their interaction as applied to medicine; SA was tested using the Visualization of Rotation (ROT) test. The intervention group (n = 29) received training and their pre‐ and post‐training scores for the SA tests were compared to a control group (n = 75). Both groups improved their mean scores in the follow‐up SA test (P < 0.010). There was no significant difference in SA scores between the groups for either SA test (P = 0.31, P = 0.90). The SA scores for female students were significantly lower than for male students, both at baseline and follow‐up (P < 0.010). Anatomy training and assessment were administered by the anatomy department of the medical school, and examination scores were not significantly different between the two groups post‐intervention (P = 0.33). However, participants with scores in the bottom quartile for SA performed worse in the anatomy questions (P < 0.001). Spatial awareness training did not improve SA or anatomy scores; however, SA may identify students who may benefit from additional academic support.
Real‐world data on incidence, clinical characteristics and outcome of patients with macrofocal multiple myeloma (MFMM) in the era of novel therapies: A study of the Greco‐Israeli collaborative myeloma working group

We investigated incidence, characteristics and outcome of patients with macrofocal multiple myeloma (MFMM) treated mainly with novel therapies. Based on definition (BMPCs <20% and lytic lesions/plasmacytomas, without anemia, renal insufficiency or hypercalcemia) we identified 140 patients with MFMM, among 4650 myeloma patients (3%). Twice the number of patients with typical myeloma were used as controls; 60% were <65 years and 70% had advanced bone disease. Plasmacytomas were more frequent in MFMM compared with standard myeloma (68% vs 15%, P < .05). Adverse prognostic parameters (high lactate dehydrogenase, advanced stage, high risk cytogenetics, immunoparesis) were less common in patients with MFMM compared with controls (P < .05); 90% received novel agents and 47% underwent autologous transplantation upfront; 90% achieved an objective response; 70% had at least very good partial response which was significantly higher compared with controls (P < .05). After a median follow‐up of 52 months, 33 patients have died. Early death (<12 months) was infrequent in MFMM. Median progression‐free survival and overall survival (OS) were 46 and 129 months respectively, both significantly longer compared with controls (P < .001). Proteasome inhibitor (PI)‐based therapy was the only independent predictor for OS in the multivariate analysis (HR: 3.9; P < .001). In conclusion, MFMM is a distinct entity presented in young and elderly subjects, characterized by limited bone marrow infiltration, advanced bone disease and frequent presence of plasmacytomas; MFMM patients have less often adverse prognostic features and achieve excellent responses and prolonged OS especially when treated with PI‐based therapies. Novel imaging will help in a more accurate classification of this entity.
Sodium ion capacitors: materials, mechanism and challenges.

Sodium ion capacitors (SICs), as designed to deliver high energy density, rapid energy delivery, and long lifespan, have attracted much attention because of their comparable performance to lithium ion capacitors (LICs), albeit with abundant sodium sources. The conventional SICs design is based on battery-like anode and capacitive cathode, in which the battery-like anode materials involve various reactions such as inserted reaction, alloying reaction and conversion reaction, and the capacitive cathode materials usually depend on activated carbon (AC). However, researchers attempted to construct SICs based on battery-like cathode and capacitive anode or a combination of both in recent years. Here, the charge storage mechanism and material design strategies in SICs are summarized, with a focus on battery-like anode materials from inorganic to organic materials. Additionally, the challenges in the fabrication of SICs and future research directions are discussed.
Thyroid dysfunction and cancer incidence: a systematic review and meta-analysis.

In this study, we aimed to evaluate site-specific cancer risks associated with hyperthyroidism or hypothyroidism. We performed a systematic review of observational studies reporting associations between hyperthyroidism or hypothyroidism and subsequent site-specific cancer incidence, in MEDLINE and the COCHRANE library (inception-28/01/2019) (PROSPERO: CRD42019125094). We excluded studies with thyroid dysfunction evaluated as a cancer biomarker or after prior cancer diagnosis, and those considering transient thyroid dysfunction during pregnancy or severe illnesses. Risk of bias was assessed using a modified Newcastle-Ottawa scale. Risk estimates were pooled using random-effects models when ≥5 studies reported data for a specific cancer site. Twenty studies were included, of which 15 contributed to the meta-analysis. Compared to euthyroidism, hyperthyroidism was associated with higher risks of thyroid (pooled risk ratio: 4.49, 95%CI: 2.84-7.12), breast (pooled risk ratio: 1.20, 95%CI: 1.04-1.38), and prostate (pooled risk ratio: 1.35, 95%CI: 1.05-1.74), but not respiratory tract (pooled risk ratio: 1.06, 95%CI: 0.80-1.42) cancers. Hypothyroidism was associated with a higher risk of thyroid cancer within the first 10 years of follow-up only (pooled risk ratio: 3.31, 95%CI: 1.20-9.13). There was no or limited evidence of thyroid dysfunction-related risks of other cancer sites. In conclusion, thyroid dysfunction was associated with increased risks of thyroid, breast, and prostate cancers. However, it remains unclear whether these findings represent causal relationships because information on treatments and potential confounders was frequently lacking.
Diagnostic accuracy of three ultrasonography strategies for deep vein thrombosis of the lower extremity: A systematic review and meta-analysis

Background Compression ultrasonography (CUS) is the first-line imaging test in the diagnostic management of suspected deep vein thrombosis (DVT) of the lower extremity. Three CUS strategies are used in clinical practice. However, their relative diagnostic accuracy is uncertain. Objectives This systematic review and meta-analysis aimed to summarize and compare the diagnostic accuracy of single limited, serial limited, and whole-leg CUS for DVT. Methods MEDLINE, Embase, and CENTRAL were searched from January 1st, 1989 to July 23rd, 2019 for studies assessing at least one of the CUS strategies in adults with suspected DVT of the lower extremity, using clinical follow-up for venous thromboembolism or contrast venography as the reference standard. Study selection, data extraction, and risk of bias assessment were performed in duplicate by independent authors. A bivariate random-effects model was used to compute diagnostic accuracy summary estimates. Results Forty studies (n = 21,250) were included. The venous thromboembolic event rate after a negative CUS (failure rate) of single limited (1.4%; 95% CI, 0.83–2.5), serial limited (1.9%; 95% CI, 1.4–2.5), and whole-leg CUS (1.0%; 95% CI, 0.6–1.6) did not differ significantly. The proportion of positive results was lower with single limited CUS, as was DVT prevalence in this group. Conclusions The failure rates of single limited, serial limited, and whole-leg CUS for DVT appeared to be quite comparable. The relative failure rate of single limited CUS remains uncertain, as the DVT prevalence was lower in these studies. Therefore, this CUS strategy may only be safe in a selected group of low-risk patients. Preference for one of the strategies may be based on pretest probability assessment, feasibility, expertise, and perceived clinical relevance of isolated distal DVT.
Computed tomography‐derived left atrial volume index, sex, and age to predict the presence and the extent of left atrial low‐voltage zones in patients with atrial fibrillation: The ZAQ score

Pulmonary vein isolation is the cornerstone of catheter ablation in patients with atrial fibrillation (AF). However, with advanced left atrial (LA) structural changes, additional targeted catheter ablation of low‐voltage zones (LVZs) has produced favorable results. Therefore, with the advent of single‐shot techniques, it would be helpful to predict the presence of LVZs before an ablation procedure.
Risk factors for loneliness: The high relative importance of age versus other factors

Loneliness is a potent predictor of negative health outcomes, making it important to identify risk factors for loneliness. Though extant studies have identified characteristics associated with loneliness, less is known about the cumulative and relative importance of these factors, and how their interaction may impact loneliness. Here, 4,885 individuals ages 10–97 years from the US completed the three-item UCLA Loneliness Survey on TestMyBrain.org. Using census data, we calculated the population and community household income of participants’ census area, and the proportion of individuals in the participant’s census area that shared the participant’s demographic characteristics (i.e., sociodemographic density). We evaluated the relative importance of three classes of variables for loneliness risk: those related to the person (e.g., age), place (e.g., community household income), and the interaction of person X place (sociodemographic density). We find that loneliness is highly prevalent and best explained by person (age) and place (community household income) characteristics. Of the variance in loneliness accounted for, the overwhelming majority was explained by age with loneliness peaking at 19 years and declining thereafter. The congruence between one’s sociodemographic characteristics and that of one’s neighborhood had no impact on loneliness. These data may have important implications for public health interventions.
Do ground-glass opacity-dominant features have prognostic significance in node-negative adenocarcinomas with invasive components of similar sizes?

OBJECTIVES The purpose of this study was to analyse the prognostic significance of the dominant features of ground-glass opacities (GGOs) in part-solid node-negative adenocarcinomas with invasive components of similar sizes. METHODS From 2004 to 2017, a total of 544 patients with a diagnosis of part-solid pathological node-negative adenocarcinoma with an invasive component <20 mm in size were selected. The enrolled patients were categorized into 2 groups: a GGO-dominant [50% < GGO (%) < 100%, n = 245] group (group 1) and a solid-dominant [0% < GGO (%) ≤ 50%, n = 299] group (group 2). To analyse the prognostic significance of GGO-dominant features, propensity score matching incorporating variables such as age, sex, preoperative pulmonary function, operation methods and size of the solid component was performed. RESULTS Propensity score matching produced 92 patients in each group for the prognostic analysis. The mean size of the solid part was 8.8 mm in the GGO-dominant group and 9.0 mm in the solid-dominant group (P = 0.34); the mean size of the total lesion was 22.2 mm in the GGO-dominant group and 14.9 mm in the solid-dominant group (P < 0.001). The 5-year overall survival rates were 96.7% in group 1 and 96.2% in group 2 (P = 0.52), and the 5-year disease-free survival rates were 96.7% in group 1 and 94.3% in group 2 (P = 0.48). CONCLUSIONS Although the total sizes of the GGO-dominant lesions were larger than those of the solid-dominant lesions, the prognosis of patients with GGO-dominant lesions was not significantly different from that of patients with solid-dominant lesions in node-negative adenocarcinomas with a similar invasive component size <20 mm.
Processed Food Additive Microbial Transglutaminase and Its Cross-Linked Gliadin Complexes Are Potential Public Health Concerns in Celiac Disease

Microbial transglutaminase (mTG) is a survival factor for microbes, but yeasts, fungi, and plants also produce transglutaminase. mTG is a cross-linker that is heavily consumed as a protein glue in multiple processed food industries. According to the manufacturers’ claims, microbial transglutaminase and its cross-linked products are safe, i.e., nonallergenic, nonimmunogenic, and nonpathogenic. The regulatory authorities declare it as “generally recognized as safe” for public users. However, scientific observations are accumulating concerning its undesirable effects on human health. Functionally, mTG imitates its family member, tissue transglutaminase, which is the autoantigen of celiac disease. Both these transglutaminases mediate cross-linked complexes, which are immunogenic in celiac patients. The enzyme enhances intestinal permeability, suppresses mechanical (mucus) and immunological (anti phagocytic) enteric protective barriers, stimulates luminal bacterial growth, and augments the uptake of gliadin peptide. mTG and gliadin molecules are cotranscytosed through the enterocytes and deposited subepithelially. Moreover, mucosal dendritic cell surface transglutaminase induces gliadin endocytosis, and the enzyme-treated wheat products are immunoreactive in CD patients. The present review summarizes and updates the potentially detrimental effects of mTG, aiming to stimulate scientific and regulatory debates on its safety, to protect the public from the enzyme’s unwanted effects.
Physician and behavioral health provider diagnostic agreement in a general hospital setting

Objective Behavioral health providers are often employed in inpatient settings. However, it is unclear if there is mental health diagnosis agreement between referring physicians and behavioral health providers. The purpose of this study is to assess for referring physician and behavioral health provider mental health diagnostic agreement in a general hospital setting. Method An analysis of 60 consecutive inpatient referrals to a behavioral health provider in a general hospital setting was conducted. The initial referral diagnosis from referring internal medicine physicians was compared with the diagnosis made by the behavioral health provider. Results Kappa statistics indicated good diagnostic agreement for substance abuse (.79), anxiety disorders (.82), adjustment disorders (.88), relational conflict (.88), and “other” (.74). There was less agreement for depressive disorders (.55). Conclusions Diagnostic agreement was good overall, suggesting that referrals to inpatient behavioral health providers are often appropriate. Results indicated that depression was underdiagnosed by physicians in the study sample. This is problematic given that depression can be successfully treated through the use of medication and psychotherapy.
Combined transepicardial and transseptal implantation of autologous CD 133+ bone marrow cells during bypass grafting improves cardiac function in patients with low ejection fraction

Autologous CD133+ bone marrow stem cells may improve cardiac function. This randomized, single‐blind clinical trial inquired whether a combined transepicardial and transseptal implantation of CD133+ stem cells during coronary artery bypass grafting (CABG) improve cardiac function with ejection fraction (EF) changes as a primary endpoint in patients with low EF.
Development of Coumarin-Based Hydroxamates as Histone Deacetylase Inhibitors with Antitumor Activities

Histone deacetylases (HDACs) have been proved to be promising targets for the treatment of cancer, and five histone deacetylase inhibitors (HDACis) have been approved on the market for the treatment of different lymphomas. In our previous work, we designed a series of novel coumarin-containing hydroxamate HDACis, among which compounds 6 and 7 displayed promising activities against tumor growth. Based on a molecular docking study, we further developed 26 additional analogues with the aim to improve activity of designed compounds. Several of these new derivatives not only showed excellent HDAC1 inhibitory effects, but also displayed significant growth inhibitory activities against four human cancer cell lines. Representative compounds, 13a and 13c, showed potent anti-proliferative activities against solid tumor cell lines with IC50 values of 0.36–2.91 µM and low cytotoxicity against Beas-2B and L-02 normal cells. Immunoblot analysis revealed that 13a and 13c dose-dependently increased the acetylation of histone H3 and H4. Importantly, the two compounds displayed much better anti-metastatic effects than SAHA against the MDA-MB-231 cell line. Moreover, 13a and 13c arrested MDA-MB-231 cells at G2/M phase and induced MDA-MB-231 cell apoptosis. Finally, the molecular docking study rationalized the high potency of compound 13c.
Percepção e atitudes do ser humano sobre guarda responsável, zoonoses, controle populacional e cães em vias públicas* Perception and attitudes of the sample population on responsible custody, zoonosis and stray dogs

This study aimed to evaluate the perception of responsible custody, zoonosis, population control of cats and dogs and the situation of stray dogs in a sample of people belonging to the Pontifical Catholic University of Parana. For this online questionnaires with 22 questions was sent. 239 people participated in this survey, the majority were female, aged between 25-35 years with complete living mainly in Curitiba / PR higher education. They had a dog or cat as a pet, 57% of respondents, and relative to the amount of animals responding by, the average number of dogs was 2.62 ± 1.35 and 1.56 ± 1.07 for cats. Both dog owners like cats, practicing regularly said vaccination administration of wormers and vet care for their animals. The access of the street dogs was held with collar and leash by 50.53% of respondents. Regarding zoonosis, 62% claimed to know what it is and managed to cite an example. About the presence of loose animals in your neighborhood, 78% of respondents said yes, 49% noted that there stray dogs that are kept by someone, and 71% stated that the responsibility for controlling these animals should be the government and society. Given the responses, we found that this sample population recognized six types of zoonosis, realized the importance of responsible dog guard and cats and stated that there is no single responsible for stray dogs.
To strive, to seek, to find, and not to yield: Narratives on the road to asylum

This study aimed to explore the ecological influences on subjective well-being identified by current and former community-dwelling asylum seekers engaged in the process of Refugee Status Determination in Australia. This article presents the qualitative component of a prospective mixed-methods study of 131 asylum seekers and refugees (T1, N = 131; T2, N = 56). The Framework Analysis method was employed to qualitatively analyse the narrative data derived from 187 semi-structured interviews documenting pre-, peri-, and post-migration experiences, and the impact of Australia’s asylum policies and procedures. Four overarching themes comprising 15 sub-themes emerged: The Refugee Status Determination process (Waiting; Uncertainty; Worry); Psychosocial factors (Un/employment & gainful activity; Medicare; Accommodation; Family separation & loneliness; Loss); Health and well-being (Mental health; Physical health & somatic issues; Hopelessness; Helplessness); and Protective factors (Hope; Support & social connectivity; Religion). The complex interface between the Refugee Status Determination process, un/employment, and mental health concerns was the most salient finding. Policy implications are discussed in relation to the application of the Convention and Protocol Relating to the Status of Refugees and the Guidelines on the Judicial Approach to Expert Medical Evidence.
